Background: When parents bring their child to appointments and then adhere to agreed speech and language therapy (SLT) recommendations, there is the potential to increase the intensity of the intervention, support generalization and improve outcomes. In SLT, however, little is known about factors that may promote attendance or adherence. Studies in other clinical areas such in medicine, psychology and physiotherapy have identified risk factors for non‐attendance or non‐adherence that are multifactorial and variable dependent on, for example, population and intervention. Aims: To identify rates of non‐attendance and non‐adherence, and to identify parent or child factors associated with parent involvement in intervention for children under 5 years of age receiving SLT. Methods: Parents completed questionnaires at two time points assessing the domains of parents' beliefs (problem perceptions, self‐efficacy), personal circumstances (socio‐demographics, family functioning), treatment experience and child factors. Predictors of parent attendance and adherence were identified through multiple regression analyses. Non‐attendance rates were identified via local health records and non‐adherence ascertained using a specific parent‐reported measure within the treatment experience domain. Results: Participants (N = 199) were predominantly mothers, and were ethnically and socio‐economically diverse, speaking a wide range of languages. Their children presented with a range of speech, language communication needs (SLCN). The rate of non‐attendance was 25% and the main predictors of non‐attendance were maternal age, education level and two factors within the parent beliefs domain. This model explained 40% of the variance in attendance. The rate of non‐adherence in this cohort was 26% with parental rating of the importance of a recommendation and self‐efficacy beliefs predicting adherence; this explained 56% of the variance in adherence to SLT recommendations at home. Conclusions & Implications: Our research has provided preliminary evidence of the influence of parents' beliefs, personal circumstances and treatment experiences on their involvement in their child's therapy. Speech and language therapists should consider factors impacting attendance and adherence to treatment and explore parental perceptions of their child's SLCN before embarking on an intervention, a foundation for collaborative practice. A possible limitation of this study is that the levels of attrition in our sample led to generally high measured rates of participation, which should be considered in future studies. Future research should explore adherence in treatments with varying doses, with different types of SLCN or interventions and in different settings. WHAT THIS PAPER ADDS: What is already known on the subject: It is acknowledged that parent involvement in their child's therapy, such as attending and adhering to recommendations, is important but little is known about the rates of involvement and what factors may be associated with attendance and adherence in SLT. Qualitative research has explored parental involvement suggesting that beliefs about an intervention may be pertinent. Extensive research in other clinical areas suggest multiple and varied factors are influential and further exploration of particular populations and interventions is necessary. What this paper adds to the existing knowledge: This study identified rates of parental non‐attendance and non‐adherence in a cohort of predominantly mothers of children under the age of 5 years. It is the first study to measure parent adherence in SLT and identify factors that are associated parental adherence to SLT recommendations. It adds to the small body of SLT specific research in understanding risk factors for non‐attendance. What are the potential or actual clinical implications of this work?: This study highlights the need for a speech and language therapist to consider and explore parents' perspectives of their child's SLCN as a part of achieving collaboration with a parent in order to achieve the best outcomes. It provides a foundation for further systematic research into parent involvement with the ultimate aim of enhancing outcomes for children with SLCN. [ABSTRACT FROM AUTHOR]

Background: As delays or disorders in early language and communication are the most prevalent symptom in children with disabilities, early screening is crucial to promote prevention, early diagnosis, and intervention. However, to the best of our knowledge, no screening tool is available for the joint assessment of early language and social communication skills in European Portuguese (EP)‐learning children, which is critical for screening, monitoring and enrolment in appropriate early intervention services. Aims: (1) To adapt and validate the EP version of the Communication and Symbolic Behaviour Scales Developmental Profile™ (CSBS DP™) Infant–Toddler Checklist, a parental report for the screening of early language and social communication skills. (2) To conduct a cross‐cultural comparison between the EP adaptation and the original US version. Methods & Procedures: A total of 611 EP‐learning children (ages 6–24 months) were assessed on the CSBS DP Infant–Toddler Checklist. Normative data, psychometric characteristics (i.e., internal consistency and test–retest reliability), and cross‐cultural comparison between the EP and the original version were explored. Outcomes & Results: Internal consistency ranged from good to excellent and the test–retest reliability was excellent. The performance of the EP and US samples matched on almost all scores. However, EP children performed significantly better than their American peers in the Social compositive at 22 months and in the Symbolic composite at 20 months. No further differences were found. Conclusions & Implications: These findings showed that the EP CSBS DP Infant–Toddler Checklist seems to be a reliable screening tool of communicative and symbolic behaviours for EP‐learning children, which can be particularly relevant for decision‐making in clinical practice. WHAT THIS PAPER ADDS: What is already known on the subject: Early communication skills are known to be related to later language outcomes. Thus, screening tools for the early identification of children at risk for language and communication impairments, which may lead to monitoring and early intervention, have the potential to promote better outcomes. However, to the best of our knowledge, no screening tool is available for the assessment of early communication abilities in EP‐learning children. What this paper adds to existing knowledge: This study adapted and validated the EP CSBS DP Infant–Toddler Checklist, the first published parental report checklist for the assessment of early communication skills in EP. It described the psychometric characteristics of the adapted checklist, summarized the newly available normative data for EP‐learning infants and toddlers, and compared the performance of EP‐learning children with the original standardization sample reported for American English. The results demonstrated that this tool is a reliable instrument for the early screening of language, communicative and symbolic behaviours for EP‐learning children between 6 and 24 months of age. What are the potential or actual clinical implications of this work?: Given that early screening is crucial to promote prevention, early diagnosis and intervention, the availability of this tool is particularly relevant for children monitoring and their enrolment in appropriate early intervention services, helping decision‐making in clinical practice, in line with current guidelines regarding early monitoring and intervention to promote and support better outcomes. Thus, the tool and related normative data will be useful for paediatricians, family doctors, primary healthcare providers, developmental psychologists and speech–language therapists, among other professionals in the healthcare and educational fields, concerned with speech, language, and communication development and impairments.

This paper studies density estimation and regression analysis with data observed on a general unit hypersphere and contaminated by measurement errors. We establish novel density and regression estimators, and study their asymptotic properties such as the rates of convergence and asymptotic normality. We also provide two types of asymptotic confidence intervals for both density and regression functions. One type is based on the asymptotic normality of their estimators and the other type is based on the empirical likelihood technique. We present practical details on the implementation of our method as well as simulation studies and real data analysis. [ABSTRACT FROM AUTHOR]

Background: Very young children from lower socioeconomic status (SES) backgrounds often show poorer language development. Whilst there have been attempts to provide early intervention programmes, these sometimes miss the most disadvantaged groups. Aims: This report presents preliminary feasibility and effectiveness data for a novel language intervention designed for parents of toddlers in the United Kingdom. Methods and Procedures: In total, 43 UK families of 2–4‐year‐olds were recruited to the study, half of whom completed an 8‐week course (Tots Talking) focussed on parent interaction, and half of whom acted as wait‐list controls. Results and Outcomes: Results suggest that such programmes are feasible for families with 86% staying in the intervention. In addition, greater changes in underlying communication skills such as joint attention and gesture were evident compared to wait‐list controls. Conclusions and Implications: We conclude that pre‐verbal skills may be more important to measure as initial outcomes than language or vocabulary change in this population. What This Paper Adds: What is already known on the subject: Children from lower socioeconomic status (SES) backgrounds are at higher risk of communication difficulties and there is a need for community intervention programmes for very young children. What this study adds: This study suggests that such programmes can be feasible and effective, but that very early/basic communicative skills (such as joint attention) may be boosted first rather than language or vocabulary. What are the clinical implications of this work?: Children's centres and other community services could feasibly run short parent facing courses emphasising contingent communication in low SES families and other diverse groups. These may be more successful run with younger preschoolers. Joint attention may be a better focus of intervention before expecting vocabulary or language change. Community health professionals may find this information useful in referring and supporting families in need. [ABSTRACT FROM AUTHOR]

Objective: To evaluate and compare performance in the modified shuttle walk test (MSWT) with cardiorespiratory parameters and respiratory muscle strength in children with cystic fibrosis (CF) and healthy controls. Methods: A cross‐sectional study with children divided into the CF group (CFG) and healthy control group (HCG). Two MSWTs were performed and the data from the test with the longest distance walked and its cardiorespiratory parameters (blood pressure, respiratory rate, heart rate (HR), oxygen saturation, and dyspnea sensation) were considered, the last three every 4 levels. Respiratory muscle strength was evaluated using a manometer. The Wilcoxon test was used to compare the parameters before and after the MSWT, and the Mann‐Whitney and independent t‐tests were applied to compare the data between the groups. The distance walked and its association with the variation in cardiorespiratory parameters and respiratory muscle strength were analyzed by Spearman's correlation. Results: Sixty‐two children (31 in each group) participated, with an average age of 10.2 (2.1) years. Children with CF had poorer performance in the average distance walked (CFG 716.7 (274.3)) when compared to the HCG (948.0 (202.8)). Both groups exhibited an increase in all the cardiorespiratory parameters at the end of the test, but the CFG displayed less variation in some parameters. Children with CF presented a positive correlation between distance walked and respiratory muscle strength, HR variation, and systolic blood pressure. Conclusions: There was no difference in respiratory muscle strength between the groups. In the CFG, the greater the respiratory muscle strength, the better the performance in the MSWT. The CFG exhibited less variation in cardiorespiratory parameters than the HCG. Implications for physiotherapy practice: Current knowledge Maximum Effort Tests provide detailed information on physiological health and enable exercise prescription.Exercise performance could be limited in children with cystic fibrosis (CF).Exercise performance is usually associated with obstruction to expiratory airflow in CF. What this paper contributes to our knowledgeChildren with CF show preserved respiratory muscles strengthPulmonary function and respiratory muscles strength were related to exercise performance by modified shuttle walk test (MSWT).Child collaboration influences test performance.

Background: Aims: To investigate the developmental trajectory of the rate and perceptual assessment of oral diadochokinesis (DDK) in typically developing children compared with adults. Also to examine the characteristics of DDK productions in children with speech sound disorders (SSD) and the relationship between DDK production and percentage of consonants correct (PCC). Methods & Procedures: Participants were 316 typically developing children and 90 children with SSD from 3 to 9 years old, as well as 20 adults with normal speech. The mono‐, bi‐ and trisyllabic nonsense strings containing Korean tense consonants and the vowel [a] were used for DDK tasks. The number of iterations per s was measured as the DDK rate for each stimulus. The perceptual assessment of DDK productions was also performed for regularity, accuracy and rate. Outcomes & Results: The DDK rates increased throughout childhood, but the oldest children, 9‐year‐olds in the current study, did not achieve adult‐like rates for all mono‐ and trisyllabic strings. Children with SSD also did not show significant differences from typically developing children when the DDK productions were analysed using only accurate tokens. The PCC of children with SSD showed higher correlations with regularity, accuracy and rate of perceptual ratings than the timed DDK rate. Conclusions & Implications: This study highlighted the fact that the comprehensive evaluation of DDK productions may provide even more useful information about children's oral motor skills. WHAT THIS PAPER ADDS: What is already known on the subject: Rates of DDK reflect the motor skills of the articulatory systems independently of phonological skills; therefore, the tasks are widely used in the diagnostic evaluations of speech disorders in both children and adult populations. However, a substantial number of studies have questioned the validity and usefulness of DDK rates for evaluating speech abilities. Also, the literature suggested that the measure of DDK rate alone does not provide a clear and useful indication of children's oral motor skills. DDK tasks should be analysed in terms of accuracy and consistency as well as rate. What this paper adds to the existing knowledge: The literature reporting normative DDK performance has mainly been based on English speakers. As different consonants have different temporal characteristics, the linguistic and segmental features of DDK tasks can impact the DDK rate. This study established a norm for DDK rate for Korean‐speaking children and investigated the developmental trajectory of DDK performance in typically developing children compared with adults. This study suggested that the comprehensive evaluation of DDK productions may provide even more useful information about children's oral motor skills by examining the characteristics of DDK productions in children with SSD. What are the potential or actual clinical implications of this work?: This study provided normative data of young Korean‐speaking children aged 3–9 years. Normative data in children under 5 years of age are valuable given that the majority of children referred for speech difficulty assessments are between 3 and 5 years of age, but only a few studies have provided the normative data in young children. This study showed that many children could not complete DDK tasks correctly and provided additional support for the notion that other aspects of DDK performance, including accuracy and regularity, may yield more useful diagnostic indications than timed DDK rates alone.

Background: Despite increasing knowledge of social communication skills of autistic peole, the interrelatedness of different skills such as non‐linguistic comprehension, social inference and empathizing skills is not much known about. A better understanding of the complex interplay between different domains of social communication helps us to develop assessment protocols for individuals with social communication difficulties. Aims: To compare the performances of autistic young adults, young adults with autistic traits identified in childhood and control young adults in social communication tasks measuring non‐linguistic comprehension, social inference and empathizing skills. In addition, to examine associations between the different social communication measures. Methods & Procedures: Autistic young adults (n = 34), young adults with autistic traits (n = 19) and control young adults (n = 36) completed the extra‐ and paralinguistic scales of the Assessment Battery for Communication (ABaCo), the Faux Pas Recognition Test, Social–Pragmatic Questions (SoPra) and the Empathy Quotient (EQ). Outcomes & Results: Group differences were found in the performance in the ABaCo, SoPra and EQ scores. Compared with the control young adults, autistic young adults scored lower. The performance of the young adults in the autistic traits group fell in between the other two groups. There were no group differences in the Faux Pas Recognition Test. The variability within the groups was large in all measurements. In the control group, there was a significant correlation between EQ and SoPra scores and between the Faux Pas and SoPra scores. In the autistic group, a significant correlation was found between Faux Pas and SoPra scores. Also, other patterns were observed but these were not statistically significant. Conclusions & Implications: The young adults with autistic traits fell in between the control and autistic young adults, highlighting the presence of the continuum in the terms of features of social communication. The results support other current research that suggests that theory of mind and other social communication skills may not be universally or widely impaired in all autistic individuals without cognitive deficits. Although all tasks examined social communication skills, only a small number of significant correlations were found between test scores. This highlights that clinical conclusions about a person's social communication should be based on the outcomes of different types of methods measuring different aspects of social communication. It is clear that the interrelatedness of different social communication skills needs further research. What This Paper Adds: What is already known on this subject: For successful communication, the ability to infer others' emotions, intentions and mental states is crucial. Autistic people have difficulty with many aspects of social communication. However, the associations between different aspects of social communication need to be better understood. What this paper adds to existing knowledge: The unique contribution of this study is to compare the performance of autistic people not only with that of a control group but also with people with childhood autistic traits. This provides an understanding of the interrelatedness of different social communication skills in people with varying degrees of autistic traits. This study used four assessment methods focusing on three different social communication elements (non‐linguistic comprehension, social inference and empathizing skills). These elements have complex relationships to one another, some being closely overlapping, some more distally related and some reflect more complex multifactorial elements. This study shows that although groups differ from each other in most of the assessments, the performance of different groups overlapped showing that many autistic young adults can perform well in non‐linguistic and social inference tasks in structured assessment contexts. What are the potential or actual clinical implications of this work?: Our findings suggest that in the assessment of social communication, self‐reports and clinical assessments can be used effectively together. They can complement each other, pointing out the strengths and weaknesses of a person, leading to more personalized therapeutic interventions. [ABSTRACT FROM AUTHOR]

Aims: Empirical investigations reveal that, in comparison to their typically developing peers, children with histories of prenatal alcohol exposure experience deficits in writing but not drawing skills, both of which require fine motor control. This study examines drawing skills in this clinical group by assessing simple free‐form spiral drawings with indices of spectral features and structural organization. Methods: Children with (n = 15) and without (n = 24) prenatal alcohol exposure used their dominant and nondominant hands to draw a series of spirals using a wireless pen stylus that either provided concurrent visual feedback in the form of a black ink trace or left no visible ink trace of each drawing. Spirals were drawn on a sheet of paper placed on a digitizing table, which facilitated online data acquisition. The data were assessed by power spectral density function analysis and sample entropy analysis. Results: In comparison to their typically developing peers, children with prenatal alcohol exposure produced spirals with a lower mean frequency and less spectral variability. Spirals in the prenatally exposed group were also lower in complexity and structural organization than in the control group. These results occurred independently of hand dominance or the availability of visual feedback. Conclusions: The drawing skills of children with prenatal alcohol exposure have inherent signal characteristics that differ significantly from those produced by typically developing peers. Simple tasks requiring fine motor control may be useful in identifying individuals with fetal alcohol spectrum disorders. [ABSTRACT FROM AUTHOR]

Citation counts are widely used as indicators of research quality to support or replace human peer review and for lists of top cited papers, researchers, and institutions. Nevertheless, the relationship between citations and research quality is poorly evidenced. We report the first large‐scale science‐wide academic evaluation of the relationship between research quality and citations (field normalized citation counts), correlating them for 87,739 journal articles in 34 field‐based UK Units of Assessment (UoA). The two correlate positively in all academic fields, from very weak (0.1) to strong (0.5), reflecting broadly linear relationships in all fields. We give the first evidence that the correlations are positive even across the arts and humanities. The patterns are similar for the field classification schemes of Scopus and Dimensions.ai, although varying for some individual subjects and therefore more uncertain for these. We also show for the first time that no field has a citation threshold beyond which all articles are excellent quality, so lists of top cited articles are not pure collections of excellence, and neither is any top citation percentile indicator. Thus, while appropriately field normalized citations associate positively with research quality in all fields, they never perfectly reflect it, even at high values. [ABSTRACT FROM AUTHOR]

Purpose: The aim of this study was a clinical validation of the NANDA‐I nursing diagnosis "Impaired Resilience (00210)" in people under fertility treatment and determination of the sensitivity, specificity, and predictive value of the defining characteristics. Methods: A cross‐sectional study was conducted between September 2019 and June 2020. A total of 104 patients were recruited through fertility‐related websites, and they answered an online questionnaire after giving informed consent. The Rasch model was used for statistical analysis. The study was approved by the Ethics Committee. Findings: The "Impaired Resilience (00210)" had a prevalence of 15.4% in the sample, and seven defining characteristics confirmed as representative are "decreased interest in vocational activities," "depression," "impaired health status," "ineffective coping strategies," "low self‐esteem," "renewed elevation of distress," and "social isolation." No item showed differential item functioning. "Renewed elevation of distress" and "low self‐esteem" were the most sensitive defining characteristics and had the highest negative predictive value. "Shame" was the most specific one. Conclusions: The nursing diagnosis "Impaired Resilience (00210)" was validated, and results may improve its accuracy in people going through fertility treatment. Implications for nursing practice: This paper contributes by raising knowledge regarding NANDA‐I nursing diagnosis and enhancing the quality of nurses' critical judgment and clinical reasoning. A more effective assessment will allow early recognition of patients struggling with adversity during fertility treatment and enhance a nursing resilience approach in the reproductive field.

Background: Texture‐modified foods (TMF) is a common intervention for improving swallowing safety and efficiency for people with dysphagia. Non‐standardized texture classification (NSTC) of foods is used worldwide. However, as this study documents, it can introduce a lack of clarity and confusion over definitions that can potentially harm patients' safety. The International Dysphagia Diet Standardisation Initiative (IDDSI) framework offers international terminology and standardized methods for texture testing that can address this issue Aims: To document differences between NSTC and standardized texture classification (STC) of the IDDSI, to document changes in the STC in the 30 min following meal delivery, and to explore the relationship between food intake and texture level. Methods & Procedures: In this observational study, data were collected from 24 long‐term care departments during five meals served to 624 residents, including at least one breakfast, lunch and dinner. To document differences between NSTC and STC, all NSTC food textures used in the LTC facilities were reclassified to match the IDDSI texture level at the time food left the kitchen (n = 1276). To document time‐related changes in texture, the STC texture as food left the kitchen was compared with texture 30 min later (n = 1276). Finally, to explore the relationship between texture and consumption, estimates were made of single‐item food consumption (n = 3820) using a subjective evaluation of consumption percentage Outcomes & Results: A total of 1276 food items were classified over the course of five meal services (with at least one each from breakfast, lunch and dinner). Statistically significant differences in NSTC and STC texture levels were found that revealed that residents were consuming food that was more difficult to eat than intended by the TMF prescription. In addition, significant changes in food texture were found over time, with texture levels significantly increasing 30 min after food left the kitchen. Finally, greater consumption was found for softer textures in comparison with regular foods; moreover, food consumption was greatest during breakfast and lowest during lunch. Conclusions & Implications: Residents requiring TMF received harder textures than intended which required complex swallowing ability, thus introducing a choking risk. Using the STC as proposed by the IDDSI could improve patient safety, oral intake and nutritional status. Time‐related changes should also be considered in circumstances where patients do not consume food soon after service. Lastly, reduced food consumption during lunch might negatively impact overall nutrient intake, particularly in cultures where lunch is the main meal of the day. What this paper adds: What is already known on the subject: Despite widespread agreement on the importance of STC, institutional care providers widely use NSTC. The IDDSI framework offers international terminology and standardized methods for texture testing. The clinical importance of using STC is not well understood. What this paper adds to existing knowledge: This study found that residents who required texture‐modified foods were eating food textures that were more challenging to swallow than intended. Differences were found in food texture between when it left the kitchen compared with texture 30 min later. Pureed texture had greater consumption than regular textured food. Food consumption was found to be the highest during breakfast, and reduced during lunch, which might negatively impact overall nutrient intake. What are the potential or actual clinical implications of this work?: Accurate food texture prescription is the first step towards increasing patients' safety. However, food preparation and handling are also very important steps, not to be disregarded. Time‐related changes in food texture are remarkable and should be considered in circumstances where patients do not consume food soon after service, as these can compromise patients' safety.

Background: Skill integration is vital in students' mastery development and is especially prominent in developing code tracing skills which are foundational to programming, an increasingly important area in the current STEM education. However, instructional design to support skill integration in learning technologies has been limited. Objectives: The current work presents the development and empirical evaluation of instructional design targeting students' difficulties in code tracing particularly in integrating component skills in the Trace Table Tutor (T3), an intelligent tutoring system. Methods: Beyond the instructional features of active learning, step‐level support, and individualized problem selection of intelligent tutoring systems (ITS), the instructional design of T3 (e.g., hints, problem types, problem selection) was optimized to target skill integration based on a domain model where integrative skills were represented as combinations of component skills. We conducted an experimental study in a university‐level introductory Python programming course and obtained three findings. Results and Conclusions: First, the instructional features of the ITS technology support effective learning of code tracing, as evidenced by significant learning gains (medium‐to‐large effect sizes). Second, performance data supports the existence of integrative skills beyond component skills. Third, an instructional design focused on integrative skills yields learning benefits beyond a design without such focus, such as improving performance efficiency (medium‐to‐large effect sizes). Major Takeaways: Our work demonstrates the value of designing for skill integration in learning technologies and the effectiveness of the ITS technology for computing education, as well as provides general implications for designing learning technologies to foster robust learning. Lay Description: What is currently known about the subject matter?: Skill integration is vital in students' mastery development, and is especially prominent in developing coding tracing skills.Coding tracing skills are foundational to programming, an increasingly important area in the current STEM education, yet many novice students struggle with code tracing.Instructional design to support skill integration in learning technologies has been limited.One of the most effective technologies for skill mastery, intelligent tutoring systems (ITS), is underused or only used in a partial form in programming education. What our paper adds to this?: We present the development and empirical evaluation of instructional design targeting students' difficulties in code tracing particularly in integrating component skills in an ITS, the Trace Table Tutor.The instructional features of the ITS technology (e.g., active learning, step‐level support, individualized problem selection) support effective learning of code tracing.Students' performance data supports the existence of integrative skills beyond component skills.An instructional design that provides deliberate practice and focused practice on integrative skills yields learning benefits beyond a design without such features. The implications of study findings for practitioners: Designing for skill integration is valuable and should receive more attention in designing learning technologies to foster robust learning.The instructional features of full‐scale ITSs are effective in supporting learning and merit further application in learning technologies in computing education.

Background: The coronavirus pandemic has affected education worldwide. Estonian schools moved to distance learning on March 16. Objectives: This paper outlines the stages of unexpected and temporary changes affecting different stakeholders based on activity and content of the messages in the Facebook group 'Homeschooling with technology'. Also the applicability of the concerns‐based adoption model was explored to explain these changes. Methods: The investigated timespan includes the week before the emergency situation and the weeks of the school term and school holidays during the emergency situation, with 52 days in total, divided into seven periods. The 872 messages were coded by two researchers and changes were examined. Results and Conclusions: Four stages were identified, from low exposure and involvement with the change to focusing on collaboration and skipping the consequence stage. Furthermore, the new changes in the educational system might focus people again on personal concerns. Implications: The results help capture the changes in teaching and learning situation caused by the coronavirus pandemic in order to learn from these changes and be prepared for such situations in the future. Lay Description: What is already known about this topicIn the emergency situation, even well‐experienced teachers were not sure what and how to teach.There are several models and there are different models on handling the changes in education.Concerns‐based adoption model (CBAM) looks at how change affects people.Emotions have changed from negative to neutral in social media during school closures What this paper addsPrevious studies have been based mostly on surveys, but this paper adds an in‐depth analysis of messages from social media.Four stages describing how changes affect people have identified.New changes brought back personal concerns and no impact concerns raised.CBAM model is applicable in explaining unexpected temporary changes Implications for practice and/or policyIn teacher training, curricula courses about distance learning methodologies and tools should be added.National guidelines about the management of distance learning situations should be prepared.

Background & Aims: Given that standardized language measures alone are inadequate for identifying functionally defined developmental language disorder (fDLD), this study investigated whether non‐linguistic cognitive abilities (procedural learning, motor functions, executive attention, processing speed) can increase the prediction accuracy of fDLD in children in linguistically diverse settings. Methods & Procedures: We examined non‐linguistic cognitive abilities in mono‐ and bilingual school‐aged children (ages 8–12) with and without fDLD. Typically developing (TD) children (14 monolinguals, 12 bilinguals) and children with fDLD (28 monolinguals, 12 bilinguals) completed tasks measuring motor functions, procedural learning, executive attention and processing speed. Children were assigned as fDLD based on parental or professional concerns regarding children's daily language functioning. If no concerns were present, children were assigned as TD. Standardized English scores, non‐verbal IQ scores and years of maternal education were also obtained. Likelihood ratios were used to examine how well each measure separated the fDLD versus TD groups. A binary logistic regression was used to test whether combined measures enhanced the prediction of identifying fDLD status. Outcomes & Results: A combination of linguistic and non‐linguistic measures provided the best distinction between fDLD and TD for both mono‐ and bilingual groups. For monolingual children, the combined measures include English language scores, functional motor abilities and processing speed, whereas for bilinguals, the combined measures include English language scores and procedural learning. Conclusions & Implications: A combination of non‐linguistic and linguistic measures significantly improved the distinction between fDLD and TD for both mono‐ and bilingual groups. This study supports the possibility of using non‐linguistic cognitive measures to identify fDLD in linguistically diverse settings. What this paper adds: What is already known on the subject: Given that standardized English language measures may fail to identify functional language disorder, we examined whether supplementing English language measures with non‐linguistic cognitive tasks could resolve the problem. Our study is based on the hypothesis that non‐linguistic cognitive abilities contribute to language processing and learning. This is further supported by previous findings that children with language disorder exhibit non‐linguistic cognitive deficits. What this paper adds to existing knowledge: The results indicated that a combination of linguistic and non‐linguistic cognitive abilities increased the prediction of functional language disorder in both mono‐ and bilingual children. What are the potential or actual clinical implications of this work?: This study supports the possibility of using non‐linguistic cognitive measures to identify the risk of language disorder in linguistically diverse settings.

Background: Dysphagia is a highly prevalent condition and affects a wide range of cohorts. A common compensatory strategy to manage dysphagia is diet modification. However, this technique is often associated with poor patient quality of life and adverse long‐term effects. Carbonated liquids have shown promise as an alternative compensatory strategy for the management of dysphagia. Aims: To examine the effect of genetic taste status and intensity of carbonation on swallowing and palatability in a healthy young adult population. To examine the palatability of carbonated liquids over time. Methods & Procedures: A total of 35 healthy young adults were recruited for this prospective, quantitative cohort study. They each drank 150 ml of still water (SW), lightly carbonated water (LCW) and highly carbonated water (HCW). Swallow function, palatability and genetic taste status were assessed using the timed water swallow test, the hedonic general labelled magnitude scale and participant ratings of the bitterness of propylthiouracil strips, respectively. Participants were divided into groups of supertasters, moderate tasters and non‐tasters. Outcomes & Results: A significant difference was found between SW and HCW on three tests of swallow function. Average time per swallow increased (p = 0.03), average swallow velocity decreased (p = 0.001) and average volume per swallow decreased (p = 0.017) on HCW compared with SW. HCW had a greater impact on swallow function than LCW. A significant mean difference in palatability ratings was found across intensity levels of carbonated fluids (p = 0.002), specifically between SW and HCW (p = 0.001). HCW was less palatable than SW. The palatability of carbonated liquids, investigated within a subgroup of five participants, did not decrease after a 24‐h period during which participants only drank carbonated liquids (p = 0.102). A significant difference was found between supertasters' (n = 9) (mean = 13.33) and non‐tasters' (n = 20) (mean = –24.5) palatability ratings of HCW (p = 0.03). Despite differences in swallow function between SW and HCW, no differences were detected between supertasters' and non‐tasters' swallow function on SW, LCW or HCW. Conclusions & Implications: Carbonated liquids have the ability to alter swallow function in a healthy young adult population; however, liquids must be highly carbonated in order to have an effect. Additionally, highly carbonated liquids are less palatable than SW, but the palatability of carbonated liquids does not decrease over time. Furthermore, supertasters find HCW more palatable than non‐tasters. These findings suggest that carbonated liquids alter swallowing in a healthy population. Further research in a clinical population is needed to better understand the potential role of sensory stimulation as a dysphagia intervention. What this paper adds: What is already known on the subject: Several studies have found that carbonated liquids have the ability to alter swallow function in both healthy and clinical populations. However, there is a lack of evidence around the optimum intensity of CO2 in carbonated liquids and the palatability of carbonated liquids as well as the palatability of carbonated fluids over time. What this paper adds to existing knowledge: The findings from this study suggest that carbonated liquids can alter swallow function in a healthy young adult population, but liquids must be highly carbonated in order to have an effect. HCW is less palatable than SW, but the palatability of carbonated liquids does not decrease over time. Additionally, supertasters find HCW more palatable than non‐supertasters (non‐tasters). What are the potential or actual clinical implications of this work?: The findings from this study suggest that carbonated liquids may be suitable for use as a sensory stimulation technique for people with dysphagia, as their palatability does not decrease over time; however, further research in a clinical population is needed in order to determine this. Additionally, intensity of stimulus is an important factor to consider during dysphagia evaluation to identify what intensity is required to optimize swallowing. [ABSTRACT FROM AUTHOR]

Background: Speech intelligibility is a global indicator of the severity of a speech problem. It is a measure that has been used frequently in research and clinical assessment of speech. Previous studies have shown that factors, such as measurement method and listener experience, can influence speech intelligibility scores. However, these factors of speech intelligibility assessment have not yet been investigated in people with Down syndrome (DS). Aims: To compare the speech intelligibility scores in speakers with DS measured using two methods: orthographic transcription and visual analogue scale (VAS), by two groups of listeners, experienced listeners and naïve listeners. Also, to examine the relationship across the four sets of speech intelligibility scores by means of correlational analysis. Methods & Procedures: A total of 30 adolescents and adults with DS read or repeated 12 sentences from a standardized test of intelligibility for adults with dysarthria. Each sentence was saved as a separate sound file and the 360 sentences were divided to form eight sets of stimuli. A total of 32 adults (16 experienced and 16 naïve) served as listeners of speech intelligibility. Each listener heard a single set of sentences and independently estimated the level of intelligibility for each sentence using a VAS in one task and wrote down the words perceived (i.e., orthographic transcription) in another task. The order of the two tasks was counterbalanced across listeners and the tasks were completed at least 1 week apart. Outcomes & Results: Repeated‐measures analysis of variance (ANOVA), confirmed by mixed‐methods analysis, showed that the scores obtained using orthographic transcription were significantly higher than those obtained using VAS; and the experienced listeners' scores were significantly higher than the naïve listeners' scores. Spearman rank correlation analysis showed that the four sets of scores across all conditions were strongly positively correlated with each other. Conclusions & Implications: Listeners, both experienced and naïve, may udge speech in DS differently when using orthographic transcription versus VAS as the method of measurement. In addition, experienced listeners can judge speech intelligibility differently compared with listeners who are less exposed to unclear speech, which may not represent 'real‐world' functional communicative ability. Speech and language therapists should be aware of the effect of these factors when measuring intelligibility scores and direct comparison of scores obtained using different procedures and by different groups of listeners is not recommended. What this paper addsWhat is already known on the subjectPrevious research on other clinical groups (e.g., Parkinson's disease) has shown that speech intelligibility scores can vary across different measurement methods and when judged by listeners with different experience. However, these factors have not yet been investigated in people with DS.What this paper adds to existing knowledgeSimilar to the findings reported for other clinical groups, using an impressionistic measurement method, such as VAS, can result in different speech intelligibility scores compared with scores obtained from orthographic transcription in speakers with DS. Furthermore, experienced listeners can perceive intelligibility as better compared with naïve (untrained) listeners for this group.What are the potential or actual clinical implications of this work?When measuring speech intelligibility, speech and language therapists should be aware that scores obtained using orthographic transcription can be higher than those obtained using VAS. They should also be aware that their increased exposure to hearing atypical speech may cause them to judge the speech difficulty as less severe and lead to an inaccurate representation of speech performance. Speech and language therapists should consider these factors when interpreting assessment results and especially when using intelligibility measures for treatment outcomes. [ABSTRACT FROM AUTHOR]

Background: There is a lack of critical or empirical work interrogating the nature and purpose of evaluating technology use in education. Objectives: In this study, we examine the values underpinning the evaluation of technology use in education through field specialist perceptions. The study also poses critical reflections about the rigour of evaluation instruments development in the educational technology field. Method: A total of 48 domain specialists were surveyed to investigate the face and content validity of 39 items under eight constructs, with both qualitative and quantitative data from the survey analysed. Results: There was an alignment between the constructs that the specialists felt were important and the constructs that have typically been the focus of empirical studies, with field specialists indicating high relevance scores for technology (M = 3.24/4), learning outcomes (M = 3.20/4), affective elements (M = 3.19/4), behaviour (M = 3.15/4), presence/community (M = 3.07/4), teaching/pedagogy (M = 3.01/4), design (M = 2.96/4), and institutional environment (M = 2.86/4). Only a minority of other studies were found to perform face and content validity checks and even then only with small samples of respondents (usually n ≤ 5). Implications: Specialists in educational technology research confirm that all eight dimensions are important to consider when evaluating the use of technology in education. Thorough face and content validity processes should be adopted when developing educational technology evaluation instruments. Further work has validated an eight factor 28 item instrument for evaluating the use of technology in education using a large sample of students from a global open learning online course. Lay Description: What is already known about this topic: Comprehensive evaluation of technology use is essential to make decisions on learning technology strategies.There is a lack of critical work interrogating how technology use is evaluated in education.There is a need for developing evaluation instruments in the educational technology field. What this paper adds: An examination of 48 field specialist perceptions of important constructs when evaluating technology use in education.Field specialists agreed that eight constructs identified in empirical studies were relevant to educational technology evaluation.Evidence of limited face and content validation processes based on previous empirical work.A comprehensive 39‐item instrument for evaluating technology use in education. Implications of study findings for practitioners: Adopt a broad range of constructs when evaluating the use of technology in education.Apply face and content validation processes involving a large sample of experts.Consider using the 39‐item instrument to evaluate educational technology use.

Background: A total of 68% of pre‐school children with cleft palate have speech problems requiring speech therapy. There is a lack of access to regular targeted therapy. Parent training leads to positive outcomes in early communication skills in cleft palate and non‐cleft speech disorders. Connected health has been used to address inadequate access to therapy, providing intervention to those who would not otherwise receive therapy. Aims: To evaluate the speech, activity and participation outcomes of Parent Led, Therapist Supervised, Articulation Therapy (PLAT) compared with routine speech therapy intervention in parent–child dyads. Methods & Procedures: A total of 44 children, aged 2.9–7.5 years, were included in a two‐centre, two‐phase randomized controlled trial. Informed consent and assent were obtained. Participants and speech and language therapists (SLTs) were unblinded to the groups. Parents, in the parent‐trained group (n = 23), attended 2 days' training, received a detailed speech therapy programme, and undertook intervention over 12 weeks supported by the cleft specialist SLT using FaceTime and one face‐to‐face session. In the control arm (n = 21), parent–child dyads received six therapy sessions over 12 weeks with a research SLT, comparable with usual care. Speech recordings were undertaken pre‐ and post‐intervention. Percent consonant correct (PCC) was analysed by external SLTs blinded to the time and group. Activity and participation were measured using the Intelligibility in Context Scale (ICS) and Focus on Outcomes for Children Under Six (FOCUS) questionnaire. Outcomes & Results: There was no evidence of an interaction between Time and Group or an overall statistical difference between groups for PCC scores. There was a statistically significant difference over time for both groups (words: p < 0.002; confidence interval (CI) = 9.38–16.27; d = 0.57; sentences: p < 0.002; CI = 16.04–25.97; d = 0.23). Effect sizes were medium for words and small for sentences. For intelligibility and participation, there was no evidence of an interaction between Time and Group or an overall statistical difference between groups. A statistically significant difference over time was found for intelligibility (F = 29.97, d.f. = 1, 42, p < 0.001, 95 % CI = 1.45–3.15 d = 0.46) and for participation (F = 14.19, d.f. = 1, 41, p < 0.001 95% CI = 7.63–25.03; d = 0.36) with FOCUS results indicating clinically meaningful (parent‐led group) and significant (control group) change in participation. Conclusions & Implications: PLAT can be as effective as routine care in changing speech, activity and participation outcomes for children with cleft palate, when supported by a specialist cleft SLT using connected health. What this paper addsWhat is already known on this subjectOver 50% of children with cleft palate require speech therapy. However, there is a lack of timely, accessible speech therapy services in the UK and Ireland. Previous studies have shown that parents can deliver therapy effectively, and that connected health can support the delivery of speech therapy. This study aims to provide evidence that parent‐led therapy with the supervision of a specialist cleft therapist using FaceTime is effective.What this paper adds to existing knowledgeThis randomized controlled trial indicates that parents can be trained to deliver therapy for children with cleft palate speech disorders, under the supervision of an SLT. This approach results in improved speech, activity and participation outcomes similar to routine care.What are the potential or actual clinical implications of this work?This study indicates that both parent‐led articulation therapy and routine care showed meaningful gains in speech, activity and participation, and that parent‐led articulation therapy when supported by a cleft SLT using connected health could be an additional service delivery model for children with cleft palate speech disorders.

Emotions are critical to learning. However, the function of emotions in the emerging context of massive open online courses (MOOCs) has been under‐researched. The present study complemented this line of research by modelling the relation between learner emotions, engagement with videos, engagement with assignments, and self‐perceived achievement in a small private online course—a localized instance of an extended MOOC. The results suggested that whereas enjoyment, excitement, boredom, and annoyance were all significant predictors of video engagement, only excitement and annoyance were significant predictors of assignment engagement. Excitement, in particular, was the strongest or stronger predictor of both types of engagement. In addition, both types of engagement predicted self‐perceived achievement, but video engagement predicted self‐perceived achievement via the mediation of assignment engagement. Implications for designing more effective MOOCs were proposed. Lay Description: What is currently known about the subject Emotions predict engagement in learning settings other than MOOCs.Engagement predicts achievement in learning settings including MOOCs.Assignment engagement predicts achievement in MOOCs better than video engagement. What this paper adds The two types of engagement are predicted by different sets of emotions.Engagement predicts self‐perceived achievement in the SPOC.Video engagement predicts self‐perceived achievement via the mediation of assignment engagement.The majority of systematic reviews did not evaluate the quality of the primary papers which they examined. Implications for practitioners MOOC researchers should pay more attention to the design of assignments.MOOC developers should try to build more emotionally‐sound courses and platforms.

Objective: Two percent of the Japanese population is comprised of foreign residents with further increase expected due to immigration policy revisions. The purpose of this paper is to examine the healthcare needs and difficulties experienced by foreign residents in Japan by level of their Japanese language fluency. Design: A quantitative, descriptive design was used. Sample: We surveyed foreign residents in the greater Tokyo area (N = 209). Measurements: The research team created the survey questions and the contents of the survey include foreign residents' experiences during their visits or stays at medical and public health facilities in Japan. Results: More than 90% of the participants or their families visited medical facilities in Japan regardless of Japanese language fluency; however, those with less Japanese language fluency experienced statistically significant uneasiness or inconvenience concerning communication compared to those with native Japanese language fluency (p =.000). Conclusions: Nurses in Japan may benefit from additional training related to use of interpreters as well as education about diversity and cultural humility. Through better understanding of the specific communication barriers of foreign residents, nurses will be able to better anticipate difficulties and address them. [ABSTRACT FROM AUTHOR]

Serious games have proven to be a powerful tool in education to engage, motivate, and help students learn. However, the change in student knowledge after playing games is usually measured with traditional (paper) prequestionnaires–postquestionnaires. We propose a combination of game learning analytics and data mining techniques to predict knowledge change based on in‐game student interactions. We have tested this approach in a case study for which we have conducted preexperiments–postexperiments with 227 students playing a previously validated serious game on first aid techniques. We collected student interaction data while students played, using a game learning analytics infrastructure and the standard data format Experience API for Serious Games. After data collection, we developed and tested prediction models to determine whether knowledge, given as posttest results, can be accurately predicted. Additionally, we compared models both with and without pretest information to determine the importance of previous knowledge when predicting postgame knowledge. The high accuracy of the obtained prediction models suggests that serious games can be used not only to teach but also to measure knowledge acquisition after playing. This will simplify serious games application for educational settings and especially in the classroom easing teachers' evaluation tasks. Lay Description: What is currently known about the subject matter Serious games are a powerful tool to engage, motivate, and help students learn.Pre‐post experiments are commonly used to measure knowledge acquisition.Game learning analytics can be applied to interaction data from games. What this paper adds We present a two‐step approach combining game learning analytics and data mining to predict players' performance in serious games based on their interactions.The approach is tested in a case study with pre‐post experiments collecting interaction data with 227 students playing a serious game to determine if performance can be accurately predicted.The comparison of prediction models has helped to determine if pretest information is essential.The highly accurate prediction models obtained suggest that games can be used to teach and measure knowledge acquisition after playing. Implications of study findings for practitioners The approach aims to simplify the measurement of players' learning with serious games.It may be generalized at least to similar scenarios (e.g., games for procedural learning or game‐likesimulations) where similar interaction data are feasible.Game mechanics and educational design should define the interaction data to capture.Using an accepted standard tracking profile is a clear recommendation.

Background: Laryngeal dystonia (LD), or spasmodic dysphonia (SD), is a neurological disorder characterized by focal dystonia or involuntary spasms of the laryngeal muscles and associated voice symptoms. It is typically treated with injection of botulinum toxin (BoNT) that weakens the affected muscles. Aims: The primary purpose of this qualitative study was to explore participants' experience of living with LD and BoNT treatment. The secondary purpose was to examine those experiences as a function of participants' scores on the Communicative Participation Item Bank (CPIB). Results will enhance our understanding of restrictions in communicative participation, assist in planning intervention targeting these restrictions and aid in clinical interpretation of CPIB scores. Methods & Procedures: Semi‐structured interviews using a phenomenological tradition and focusing on BoNT treatment and communicative participation were conducted with 26 people with LD who are on established BoNT treatment regimens. Interviews were recorded, transcribed, coded and analysed inductively. Participants were categorized by CPIB scores into groups ranging from none to extensive participation restrictions. Both self‐ and expert ratings of voice were obtained. Outcomes & Results: Participants with different levels of CPIB scores had different experiences related to communicative participation in the context of BoNT treatment. These differences were organized into the following topics: BoNT and voice; attitudes toward participation; coping strategies; and advice. For all participants except those in the least restricted and most restricted groups, expert ratings of voice did not relate to CPIB scores. Conclusions & Implications: Although most participants report improved voice with BoNT treatment, many participants experienced lingering restrictions in communicative participation, some to a severe extent. Participants reported coping with these restrictions in many ways; some of these strategies were more successful than others. Those with restricted participation recommended more support for daily life and the emotional toll of LD, as well as support for family members. This support might be offered by speech–language pathologists. What this paper adds: What is already known on the subject: Participants with different levels of CPIB scores had different experiences related to communicative participation in the context of BoNT treatment. What this study adds to the existing knowledge: Although most participants report improved voice with BoNT treatment, many participants experienced lingering restrictions in communicative participation, some to a severe extent. What are the potential or actual clinical implications of this work?: SLP services that take a participation‐focused approach to intervention and use multi‐factorial approaches to help clients maximize their life participation in the context of LD are well within the SLP scope of practice. SLPs can help clients find and use their optimal voices within the constraints of the dystonia and BoNT effects. [ABSTRACT FROM AUTHOR]

Objectives: To highlight the experiences and challenges of international medical graduates (IMGs) living and working in rural and remote Tasmania, and how this informs their acculturation and retention in the state. Design: This paper reports the findings from the Tasmanian IMG questionnaire, which was administered both in hardcopy and online format to all known IMGs within the state. A total of 105 questionnaires were returned, representing a response rate of 30.0%. Results: IMGs were from the 30 countries and the majority were under 49 years of age, had migrated in the past 10 years, with over half having worked in the state for less than 2 years. Many IMGs indicated that they were satisfied with their current employment, the medical facilities, the friendliness of their patients and the friendliness of the community where they lived, and would like to stay much longer in Tasmania. Conclusions: Many IMGs have previously lived and worked in rural areas and are reasonably satisfied with their current employment and lifestyle in Tasmania. However, the following factors play an important part in their views and attitudes: employment satisfaction, access to schools, employment for spouse or partner and access to cultural or religious foods and goods. Nevertheless, beyond employment satisfaction, employment itself, coupled with career pathway and training opportunities, were highlighted as contributory factors for leaving Tasmania.

Summary: Differential privacy is a framework for data analysis that provides rigorous privacy protections for database participants. It has increasingly been accepted as the gold standard for privacy in the analytics industry, yet there are few techniques suitable for statistical inference in the health sciences. This is notably the case for regression, one of the most widely used modelling tools in clinical and epidemiological studies. This paper provides an overview of differential privacy and surveys the literature on differentially private regression, highlighting the techniques that hold the most relevance for statistical inference as practiced in clinical and epidemiological research. Research gaps and opportunities for further inquiry are identified. [ABSTRACT FROM AUTHOR]

Background: Comparative optimism, the belief that negative events are more likely to happen to others rather than to oneself, is well established in health risk research. It is unknown, however, whether comparative optimism also permeates people's health expectations and potentially behaviour during the COVID‐19 pandemic. Objectives: Data were collected through an international survey (N = 6485) exploring people's thoughts and psychosocial behaviours relating to COVID‐19. This paper reports UK data on comparative optimism. In particular, we examine the belief that negative events surrounding risk and recovery from COVID‐19 are perceived as more likely to happen to others rather than to oneself. Methods: Using online snowball sampling through social media, anonymous UK survey data were collected from N = 645 adults during weeks 5‐8 of the UK COVID‐19 lockdown. The sample was normally distributed in terms of age and reflected the UK ethnic and disability profile. Findings: Respondents demonstrated comparative optimism where they believed that as compared to others of the same age and gender, they were unlikely to experience a range of controllable (eg accidentally infect/ be infected) and uncontrollable (eg need hospitalization/ intensive care treatment if infected) COVID‐19‐related risks in the short term (P <.001). They were comparatively pessimistic (ie thinking they were more at risk than others for developing COVID‐19‐related infection or symptoms) when thinking about the next year. Discussion: This is one of the first ever studies to report compelling comparative biases in UK adults' thinking about COVID‐19. [ABSTRACT FROM AUTHOR]

Retrieval practice promotes retention more than restudying (i.e., the testing effect) and is applied to many educational settings. However, little research has investigated means to enhance this effect in educational settings. Theoretical accounts assume retrieval practice to be the most effective whenever retrieval is difficult but successful. Therefore, we developed a novel retrieval practice procedure, which adapts to learners' abilities and can be applied irrespective of learning content. This adaptive procedure aims to make retrieval gradually easier whenever students provide an incorrect answer. In a field experiment, students read book chapters as part of a weekly university course. In three consecutive weeks, they then practiced reading assignments by (a) adaptive testing, (b) non‐adaptive testing and (c) restudy. In Week 4, a surprise criterial test took place. Restudy outperformed both testing conditions, whereas adaptive testing performed equally well as non‐adaptive testing. However, exploratory analyses revealed that with increasing retention intervals, the superiority of restudy disappeared. Furthermore, whenever participants fully read the assignments and retention intervals increased, adaptive testing outperformed non‐adaptive testing. In sum, adaptive retrieval practice did not prove to be generally superior, but retention interval and students' preparation for class might be conditions rendering adaptive retrieval useful in educational settings. Lay Description: What is already known about this topic: Testing is a commonly used technique to assess progress in computer‐assisted learning environmentsStudents often benefit from the testing effect, that is practicing retrieval of information (testing) from memory benefits long‐term retention compared to restudyingCurrently, empirical evidence how to enhance the benefits of this technique in educational contexts is scarce What this paper adds: We propose a new approach to increase the benefit of the testing effect: For each question in retrieval practice the individual ability to retrieve this information from memory is consideredTo do so, cue informativeness of retrieval cues adapts to the individual ability level and thus makes the tests cognitively effortful but solvableThis adaptive approach is put to test in a higher education context and by using multiple‐choice questionsIn sum, adaptive retrieval practice did not prove to be generally superior to non‐adaptive retrieval practice or restudy However, retention interval and students' preparation for class might be conditions rendering adaptive retrieval useful in educational settings Implications for practice and/or policy: Findings can be implemented in educational contexts when multiple‐choice questions are used to enhance learningLearning can be optimized in computer‐assisted learning environments that allow adaptive testingWe advise adaptive retrieval only when students are well prepared for practice and when time between practice and final assessment exceeds two weeks [ABSTRACT FROM AUTHOR]

Online search involves multitasking and may demand better working‐memory capacities (WMC) and additional cognitive aids. Given the constraints of human cognition, we tested the effectiveness of note‐taking strategies on university students' online search performance. Also examined were the profile configurations of WMC tests in silence and in irrelevant speech as well as its interaction effects with note‐taking strategies on online search performance. Among the participants of 60 university students, we found a four‐group WMC profile composition that differed significantly across WMC scores in both silence and irrelevant speech. Results showed that WMC profiles, note‐taking groups and their interaction effect were significant factors on online search performance. Both Free Note and Matrix Note were beneficial for the students in low silent WMC profile groups. Study results have both theoretical and practical implications, advancing our understanding of the interrelationship of WMC under different conditions and informing instructional practice of online search performance. Lay Description: What is already known about this topicWorking memory capacity is fundamental to multitasking ability.Online search is a typical multitasking behavior that requires constant switching between different information sources.Students who take note perform better than those who do not while reading materials with seductive but irrelevant information.What this paper addsStudents working memory capacity is examined under silent and irrelevant speech conditions.Students exhibited different profile patterns in their working memory capacity under silent and irrelevant speech conditions.Taking note, either in matrix form or free form, can significantly improve students' online search performance for those with high WMC ONLY in irrelevant speech or for those with low WMC in both silent and irrelevant speech conditions.Implications for practiceNote‐taking as auxiliary support may facilitate students' integration and evaluation of the online information across multiple sources during their online search.Instructions on how to self‐construct matrix note are needed to help students develop advanced note‐taking skills for their learning involving online search.

Multiple imputation by chained equations (MICE) has emerged as a leading strategy for imputing missing epidemiological data due to its ease of implementation and ability to maintain unbiased effect estimates and valid inference. Within the MICE algorithm, imputation can be performed using a variety of parametric or nonparametric methods. Literature has suggested that nonparametric tree-based imputation methods outperform parametric methods in terms of bias and coverage when there are interactions or other nonlinear effects among the variables. However, these studies fail to provide a fair comparison as they do not follow the well-established recommendation that any effects in the final analysis model (including interactions) should be included in the parametric imputation model. We show via simulation that properly incorporating interactions in the parametric imputation model leads to much better performance. In fact, correctly specified parametric imputation and tree-based random forest imputation perform similarly when estimating the interaction effect. Parametric imputation leads to slightly higher coverage for the interaction effect, but it has wider confidence intervals than random forest imputation and requires correct specification of the imputation model. Epidemiologists should take care in specifying MICE imputation models, and this paper assists in that task by providing a fair comparison of parametric and tree-based imputation in MICE.

Wilks's theorem is useful for constructing confidence regions. When applying the popular empirical likelihood to data with nonignorable nonresponses, Wilks's phenomenon does not hold. This paper unveils that this is caused by the extra estimation of the nuisance parameter in the nonignorable nonresponse propensity. Motivated by this result, we propose an adjusted empirical likelihood for which Wilks's theorem holds. Asymptotic results are presented and supplemented by simulation results for finite sample performance of the point estimators and confidence regions. An analysis of a data set is included for illustration. [ABSTRACT FROM AUTHOR]

Citation data for institutes are generally provided as numbers of citations or as relative citation rates (as, for example, in the Leiden Ranking). These numbers can then be compared between the institutes. This study aims to present a new approach for the evaluation of citation data at the institutional level, based on regression models. As example data, the study includes all articles and reviews from the Web of Science for the publication year 2003 ( n = 886,416 papers). The study is based on an in-house database of the Max Planck Society. The study investigates how much the expected number of citations for a publication changes if it contains the address of an institute. The calculation of the expected values allows, on the one hand, investigating how the citation impact of the papers of an institute appears in comparison with the total of all papers. On the other hand, the expected values for several institutes can be compared with one another or with a set of randomly selected publications. Besides the institutes, the regression models include factors which can be assumed to have a general influence on citation counts (e.g., the number of authors). [ABSTRACT FROM AUTHOR]

Background Low levels of alcohol responses (low LRs) are genetically influenced phenotypes that are identified before alcohol dependence and predict future heavy drinking and alcohol problems. A recent paper described 13 LR-related blood oxygen level-dependent ( BOLD) response contrast patterns observed during an emotional face recognition task that might reflect cognitive processes contributing to LR and that might themselves predict adverse alcohol outcomes ( Paulus et al., Biol Psychiatry 2012; 72: 848). This paper evaluates the predictive implications of those functional magnetic resonance imaging (f MRI) patterns. Methods Of 120 subjects from Paulus and colleagues (2012), 114 (57 low and high LRs; ~50% females) were interviewed 5 years later at age 25. Correlations between baseline f MRI patterns and alcohol-related outcomes were evaluated, and regression analyses were used to determine if BOLD response contrasts incremented over LR in predicting outcomes. Results Baseline f MRI patterns in 5 of 13 baseline regions of interest correlated with adverse outcomes. Such patterns in insular regions, particularly the left anterior insula, and the right frontal gyrus, added to LR in predicting alcohol problems. The relationships remained robust when exact binomial procedures were used, but, reflecting the small sample size, it was not possible to adequately consider Bonferroni corrections. Conclusions The data suggest that f MRI BOLD response contrasts predicted heavier drinking and alcohol problems 5 years later, even after considering baseline low LRs. Future work will focus on whether f MRI results can predict outcomes in larger samples and among young nondrinkers, as well as how the imaging results increase understanding of the processes through which LR operates.

Abstract: The aim of this paper is to provide insights into differences between pre‐service teachers based on the areas of technological pedagogical content knowledge (TPACK) and the areas of theory of planned behaviour (TPB) in the context of using information and communication technology in education. The target group consisted of 267 first‐year pre‐service teachers at 3 Finnish universities. Differences between pre‐service teachers were outlined using cluster analysis based on their knowledge of different TPACK areas (the respondents' weak and strong areas). To see how the TPB areas aligned with the 4 TPACK clusters, 1‐way analysis of variance was used. Statistically significant differences between the 4 clusters were found in all the TPB areas except subjective norms. These results provide insights into the differences among pre‐service teachers in the context of TPACK and the TPB. They also suggest that instead of considering pre‐service teachers as one homogenous group, we need to understand the variations among their abilities and knowledge in order to be able to provide them with support they need within teacher education.

Abstract: Background and Purpose: Physiotherapy (PT) and occupational therapy (OT) are key professions providing treatment for the arm after stroke; however, knowledge about the content of these treatments is scant. Detailed data are needed to replicate interventions, evaluate their effective components, and evaluate PT and OT practice. This paper describes PT and OT treatment for the severely affected arm in terms of duration, content according to components and categories of the International Classification of Human Functioning, Disability and Health, and to analyze differences between professions. Methods: Design: This is a retrospective analysis of randomized trial data. Participants: 46 patients after stroke with poor arm motor control recruited from inpatient neurological units from three rehabilitation centers in the Netherlands. Procedure: PTs and OTs recorded duration and content of arm treatment interventions for 8 weeks using a bespoke treatment schedule with 15 International Classification of Human Functioning, Disability and Health categories. Results: PTs and OTs spent on average 4–7 min per treatment session (30 min) on arm treatment. OTs spent significantly more time providing arm treatment and treatment at the activities level than PTs. PTs spent 79% of their arm treatment time on body functions, OTs 41%. OTs spent significantly more time on “moving around using transportation,” “self care,” and “household tasks” categories. Conclusions: Patients after stroke with a severely affected arm and an unfavorable prognosis for arm motor recovery receive little arm‐oriented PT and OT. Therapists spent most arm treatment time on body functions. There was a considerable overlap in the content of PT and OT in 12 of the 15 categories. Results can be generalized only to patients with poor arm motor control and may not represent practice in other countries. [ABSTRACT FROM AUTHOR]

In clinical research, investigators are interested in inferring the average causal effect of a treatment. However, the causal parameter that can be used to derive the average causal effect is not well defined for ordinal outcomes. Although some definitions have been proposed, they are limited in that they are not identical to the well-defined causal risk for a binary outcome, which is the simplest ordinal outcome. In this paper, we propose the use of a causal parameter for an ordinal outcome, defined as the proportion that a potential outcome under one treatment condition would not be smaller than that under the other condition. For a binary outcome, this proportion is identical to the causal risk. Unfortunately, the proposed causal parameter cannot be identified, even under randomization. Therefore, we present a numerical method to calculate the sharp nonparametric bounds within a sample, reflecting the impact of confounding. When the assumption of independent potential outcomes is included, the causal parameter can be identified when randomization is in play. Then, we present exact tests and the associated confidence intervals for the relative treatment effect using the randomization-based approach, which are an extension of the existing methods for a binary outcome. Our methodologies are illustrated using data from an emetic prevention clinical trial. [ABSTRACT FROM AUTHOR]

Objective Despite increases in Commonwealth funded general practice (GP) Registrar training positions, workforce trends continue to show geographical maldistribution. This study aimed to identify Registrar attributes which describe a cohort choosing to work in rural practice. Design Cross-sectional self-report questionnaire for socio-demographics, prior training, current training pathway, measures of personality and resilience. Participants and Setting GP Registrars ( N = 452) training in either the general or rural pathways of three Registered Training Providers in three states, or training through the Australian College of Rural and Remote Medicine's independent pathway. Main outcome measure Ordinal logistic regression tested the impact of key variables on the likelihood that Registrars would settle in rural practice. Univariate analysis explored differences between groups and effects of variables. Results A significantly increased interest in rural practice was to found to exist among registrars who were male, identified themselves as being rural, had a partner who identified as being rural, were enrolled in a rural training pathway and had high levels of Cooperativeness. Conclusion We present a discriminating model combining socio-demographics, prior training and personality variables which challenges Australia to rethink Registrar attributes when training for rural general practice. With significant changes about to occur to GP training in Australia, this paper highlights the need for a more holistic approach which considers personal attributes such as Cooperativeness, rural identity and provision of geographically focused rural training pipelines to encourage Registrars to bond to individual rural communities and further develop their personal connectedness to country life and rural medical practice.

Objectives To assess the efficacy of comprehensive geriatric assessment ( CGA) in prevention of delirium after hip fracture. Design Systematic review and metaanalysis. Setting Ward based models on geriatrics wards and visiting team based models on orthopaedics wards were included. Participants Four trials (three European, one U.S.; 973 participants) were identified. Two assessed ward-based, and two assessed team-based interventions. Measurements MEDLINE, EMBASE, CINAHL and Psyc INFO databases; Clinicaltrials.gov; and the Central Register of Controlled Trials were searched. Reference lists from full-text articles were reviewed. Incidence of delirium was the primary outcome. Length of stay, delirium severity, institutionalization, long-term cognition and mortality were predefined secondary outcomes. Duration of delirium was included as a post hoc outcome. Results There was a significant reduction in delirium overall (relative risk ( RR) = 0.81, 95% confidence interval ( CI) = 0.69-0.94) in the intervention group. Post hoc subgroup analysis found this effect to be preserved in the team-based intervention group ( RR = 0.77, 95% CI = 0.61-0.98) but not the ward-based group. No significant effect was observed on any secondary outcome. Conclusion There was a reduction in the incidence of delirium after hip fracture with CGA. This is in keeping with results of non-randomized controlled trials and trials in other populations. Team-based interventions appeared superior in contrast to the Ellis CGA paper, but it is likely that heterogeneity in interventions and population studied affected this. [ABSTRACT FROM AUTHOR]

Objectives Obesity and dental caries have become increasingly prevalent challenges to public health. Research results into the relationship between obesity and dental caries in children have been mixed and inconclusive. The aim of this review and meta-analysis was to provide evidence to quantify the relationship between obesity and dental caries in children using a systematic approach. Methods A systematic search for papers between 1980 and 2010 addressing childhood obesity and dental caries was conducted and a random effects model meta-analysis applied. Results Fourteen papers met the selection criteria. Overall, a significant relationship between childhood obesity and dental caries (effect size = 0.104, P = 0.049) was found. When analysed by dentition type (primary versus permanent), there was a nonsignificant association of obesity and dental caries in permanent and primary dentitions, yet on accounting only for standardized definitions for assessment of child obesity using body mass index, a strong significant relationship was evident in children with permanent dentitions. Moderating for study country of origin (newly 'industrialized' versus industrialized) showed a significant relationship between obesity and dental caries in children from industrialized but not newly industrialized countries. Cofactors such as age and socioeconomic class were significant moderators. Conclusions Future analysis should investigate these confounding variables, helping shape the future of obesity management programmes and oral health interventions, through determining common risk factors.

The main aim of the Swedish physical activity and fitness cohort study ( SPAF-1958) was to describe physical fitness, physical activity, health, and lifestyle across part of the lifespan, and to assess the influences on these factors from the environment, personal factors, and genetics. There is inevitable dropout from longitudinal studies, and it may be systematic. The aim of this first paper of the second follow-up of SPAF-1958 was to provide a dropout analysis to consider to what extent the participants, at 52 years of age, remain a representative sample of the original adolescent study population. Additional aims were to provide an overview of the study protocol and the ongoing study population. Ongoing study participants in SPAF born in 1958 were, at the second follow-up at the age of 52, still representative of the study cohort in terms of sex, adolescent geographical area, upper secondary school program, adolescent body composition, muscular strength, and muscular endurance. However, a higher physical activity and, among women, a higher aerobic capacity in adolescence decreased the risk for dropout. It is important when interpreting results from longitudinal studies to adjust for the systematic dropout that could bias the conclusions drawn from the results. [ABSTRACT FROM AUTHOR]

The purpose of this study was twofold: (a) to investigate the prevalence of hip and groin pain in sub-elite male adult football in Denmark and (b) to explore the association between prevalence and duration of hip and groin pain in the previous season with the Copenhagen Hip and Groin Outcome Score ( HAGOS) in the beginning of the new season. In total 695 respondents from 40 teams (Division 1-4) were included. Players completed in the beginning of the new season (July-Sept 2011) a self-reported paper questionnaire on hip and/or groin pain during the previous season and HAGOS. In total 49% (95% CI: 45-52%) reported hip and/or groin pain during the previous season. Of these, 31% (95% CI: 26-36%) reported pain for >6 weeks. Players with the longest duration of pain during the previous season had the lowest HAGOS scores, when assessed at the beginning of the new season, P < 0.001. This study documents that half of sub-elite male adult football players report pain in the hip and/or groin during a football season. The football players with the longest duration of pain in previous season displayed the lowest HAGOS scores in the beginning of the new season. [ABSTRACT FROM AUTHOR]

What is already known about this subject There is an association between adiposity levels and physical activity guidelines for adolescents., Achieving physical activity recommendations helps adolescents to prevent obesity status., What this study adds This paper presents an association between physical activity levels and obesity status., This paper supports physical activity recommendations to avoid children's obesity levels., This paper emphasizes vigorous physical activity for this matter., Background There is no information about physical activity (PA) recommendations to avoid children's obesity levels and how much of vigorous PA (VPA) is included into the '60 minutes of MVPA 5 days a week' recommendation for children. Objective The aim of this study was to examine the association between PA and adiposity in children and to examine whether the current PA guidelines are associated with a low risk of having excess of body fat in children, with special focus on sex differences, and PA intensity. Methods A sample of 439 Spanish children aged 8-10 years from the European Youth Heart Study participated in the study. The variables measured were anthropometric characteristics (height, weight, body mass index [ BMI], skin-folds and waist circumference) and PA was measured during 6 consecutive days using the GT1M accelerometer. Results Receiver operating characteristic analysis showed significant cut-off points associated with non-overweight: 45 min d−1 of VPA and 67 min d−1 of moderate-to-vigorous physical activity ( MVPA) (using BMI categories); and non-fat: 41 min d−1 of VPA and 67 min d−1 of MVPA (using percentage of body fat) and 38 min d−1 of VPA and 47 min d−1 of MVPA (using waist circumference categories) for boys. For girls, the optimal cut-offs of moderate-to-vigorous activity and MVPA associated with non-overweight were 24 and 57 min d−1, respectively ( BMI). Boys who did not meet 67 min in MVPA had an increased risk of being overweight + obese and overfat + obese (odds ratio [ OR] = 2.48, 95% confidence interval [ CI] = 1.36, 4.53, and OR = 2.56, 95% CI = 1.12, 5.82). Conclusions The findings support current PA recommendations (60 min d−1 of MVPA) to avoid excess of body fat in Spanish children. However, VPA appears to be an important component for the prevention of obesity, and our findings suggest that PA recommendations should specify the dose of VPA required for optimal health. Therefore, public health PA recommendations should incorporate specifically a greater dose of VPA into the total amount of MVPA in 8- to 10-year-old boys. [ABSTRACT FROM AUTHOR]

Rationale, aims and objectives: Establishing the relationship between various doses of an exposure and a response variable is integral to many studies in health care. Linear parametric models, widely used for estimating dose–response relationships, have several limitations. This paper employs the optimal discriminant analysis (ODA) machine‐learning algorithm to determine the degree to which exposure dose can be distinguished based on the distribution of the response variable. By framing the dose–response relationship as a classification problem, machine learning can provide the same functionality as conventional models, but can additionally make individual‐level predictions, which may be helpful in practical applications like establishing responsiveness to prescribed drug regimens. Method: Using data from a study measuring the responses of blood flow in the forearm to the intra‐arterial administration of isoproterenol (separately for 9 black and 13 white men, and pooled), we compare the results estimated from a generalized estimating equations (GEE) model with those estimated using ODA. Results: Generalized estimating equations and ODA both identified many statistically significant dose–response relationships, separately by race and for pooled data. Post hoc comparisons between doses indicated ODA (based on exact P values) was consistently more conservative than GEE (based on estimated P values). Compared with ODA, GEE produced twice as many instances of paradoxical confounding (findings from analysis of pooled data that are inconsistent with findings from analyses stratified by race). Conclusions: Given its unique advantages and greater analytic flexibility, maximum‐accuracy machine‐learning methods like ODA should be considered as the primary analytic approach in dose–response applications.

Objective To examine urban-rural differences and individual risk factors for a late stage of breast cancer at diagnosis in Australian women. Design Individual-level longitudinal data were linked with cancer registry data from New South Wales (New South Wales Cancer Registry linked by the Centre for Health Record Linkage (CHeReL)), Queensland (Queensland Cancer Registry) and Victoria (The Cancer Council Victoria). Setting Participants were drawn from the Australian Longitudinal Study on Women's Health 1946-1951 cohort (n = 13 715). Participants The sample included 195 women identified from the linked cancer registry data with a breast cancer diagnosis. Interventions Rural or urban residence was measured using Accessibility/Remoteness Index of Australia Plus (ARIA+). Individual characteristics and socio-demographic variables examined included survey year, menopausal status, country of birth, education and marital status. Main outcome measures A late stage of breast cancer at diagnosis was defined based on the TNM Classification of Malignant Tumours. Results A late stage of breast cancer diagnosis was observed in 36% of women residing in urban areas and 40% of women residing in rural areas. After adjusting for individual characteristics, we found that obesity was the strongest risk factor for a late stage of breast cancer at diagnosis. Conclusions Given that women are becoming increasingly obese, and that the rate of obesity is higher in the Australian rural population, this paper provides further evidence for targeting interventions for obesity, particularly in rural Australia, as a public health priority.

Background: It has long been assumed that the development of childhood asthma is related to exposure to environmental chemicals, but it has thus far not been possible to unequivocally establish this suspected relationship using individual studies. Moreover, studies of children have been scanty and unreliable due to the large diversity of research environments and subject cohorts. The aim of the current study was to clarify this relationship for one factor by means of a meta-analysis of studies investigating the influence of NO2 exposure on symptomatology of childhood asthma. Methods: Two electronic databases (MEDLINE and EMBASE ) were searched for literature on relationships between environmental chemical exposure and development of childhood asthma using the MeSH terms 'nitrogen dioxide' and 'asthma'. This was done according to the MOOSE guidelines for meta-analyses of observational studies. Results: A total of 130 papers were retrieved, of which 12 met the selection criteria. These papers described observational studies from seven countries. Study subjects were 97 932 ordinary children aged 0-18 years. Using random model analysis, the odds ratio (OR) for asthma development due to an increment of 10 p.p.b. NO2 was 1.135 with a 95% confidence interval [CI] of 1.031-1.251 ( P= 0.01), while the OR for wheezing symptoms was 1.052 with a 95%CI of 1.020-1.085 ( P= 0.001). It is therefore evident that NO2 exposure does influence the development of asthma in ordinary children. Conclusions: Exposure to NO2 in the air significantly influences the development of childhood asthma and symptoms of wheezing. [ABSTRACT FROM AUTHOR]

Aim: This paper aims to assess the subjective quality of life (SQOL) and its correlates among older adults in rural communities of Vietnam and Indonesia. Methods: The paper uses the data from the INDEPTH/WHO Study on global aging and adult health (SAGE). The study was carried out in the FilaBavi Health and Demographic Surveillance System (HDSS) site in Vietnam and in Purworejo HDSS in Indonesia. All people aged 50 years and over who lived in these two HDSS areas were surveyed. Face-to-face household interviews were carried out by trained surveyors using the standardized summary version of the INDEPTH/WHO SAGE questionnaire. The SQOL was assessed by asking the respondents 'How would you rate your overall quality of life?' The response set was a five-point scale where 1 = Very good, 2 = Good, 3 = Moderate, 4 = Bad, 5 = Very bad. Results: In both countries, the SQOL was reported to be higher among (i) men; (ii) people with higher education; (iii) people who were in a marital partnership; (iv) people who lived with other family members; and (v) those with higher economic status, compared with that in those of other category(ies) of the same characteristic. In Vietnam, people who belonged to the second to fifth economic quintiles and had more than 6 years of education were sevenfold more likely to report very good/good quality of life compared with those who belonged to the first economic quintile (poorest) and had no formal education. The corresponding figure was 2.7 for Indonesia. Conclusions: The patterns of sociodemographic determinants of SQOL show that inequality in quality of life exists among older adults in the two study settings. Geriatr Gerontol Int 2012; 12: 397-404.

Rationale, aims and objectives Open-label extension (OLE) studies following blinded randomized controlled trials (RCTs) of pharmaceuticals are increasingly being carried out but do not conform to regulatory standards and questions surround the validity of their evidence. OLE studies are usually discussed as a homogenous group, yet substantial differences in study design still meet the definition of an OLE. We describe published papers reporting OLE studies focussing on stated objectives, design, conduct and reporting. Method A search of Embase and Medline databases for 1996 to July 2008 revealed 268 papers reporting OLE studies that met our eligibility criteria. A random sample of 50 was selected for detailed review. Results Over 80% of the studies had efficacy stated as an objective. The most common methods of allocation at the start of the OLE were for all RCT participants to switch to one active treatment or for only participants on the new drug to continue, but in three studies all participants were re-randomized at the start of the OLE. Eligibility criteria and other selection factors resulted in on average of 74% of participants in the preceding RCT(s) enrolling in the OLE and only 57% completed it. Conclusions Published OLE studies do not form a homogenous group with respect to design or retention of participants, and thus the validity of evidence from an OLE should be judged on an individual basis. The term 'open label' suggests bias through lack of blinding, but slippage in relation to the sample randomized in the preceding RCT may be the more important threat to validity.

This study compared higher education dental undergraduate student performance in online assessments with performance in traditional paper-based tests and investigated students' perceptions of the fairness and acceptability of online tests, and showed performance to be comparable. The project design involved two parallel cross-over trials, one in Year 3 ( n = 132) of the dental curriculum, one in Year 5 ( n = 134). A total of 266 students undertook related tests of the same knowledge base in both online and traditional paper formats. Order of presentation of the test form was randomized. One hundred and thirty-two students in Year 3 additionally completed questions concerning their perceptions of the acceptability and fairness of the online examination process. Focus group discussions were held with groups of students ( n = 30) from both Year 3 and 5 to explore their perceptions of the online format. The online tests were created using the commercial software package MaxExam (Bristol, UK). The results were analysed using repeated measures analysis of variance (ANOVA) with the order of presentation being entered as a variable in the analysis. The results of the study showed that for both Years 3 and 5 students there was a high degree of consistency in performance between the two versions of the tests, although a minority of students performed better in the online version of the test. Over 70% of students rated the online test as acceptable, and 90% felt that the online format did not disadvantage them even in a 'high-stakes' situation. From these results, we conclude that online assessment does not confer any disadvantage to students. Students perceive such assessment to be both fair and acceptable, and to have some advantages over the traditional paper-based methods of assessment. [ABSTRACT FROM AUTHOR]

OBJECTIVES This study aimed to investigate the relationship between the authenticity of instructional formats and outcome measures within a pre-clerkship clinical reasoning course. METHODS We conducted a randomised, prospective, crossover study with Year 2 medical students taking a pre-clerkship clinical reasoning course. Students were randomised to small groups and exposed to three formats of differing instructional authenticity (paper case, DVD presentation, standardised patient [SP] presentation) across three subject areas (abdominal pain, anaemia, polyuria). Three student cohorts were taught using one instructional format per subject area so that each cohort received a different instructional format for each of the three subject areas. Outcome measures (objective structured clinical examination, video quiz, written examination) were selected to determine the effect of each instructional format on the clinical reasoning of students. RESULTS Increasingly authentic instructional formats did not significantly improve clinical reasoning performance across all outcome measures and subject areas. However, the results of the video quiz showed significant differences in the anaemia subject area between students who had been instructed using the paper case and live SP-based formats (scores of 47.4 and 57.6, respectively; p = 0.01) and in the abdominal pain subject area, in which students instructed using the DVD format scored higher than students instructed using either the paper case or SP-based formats (scores of 41.6, 34.9 and 31.2, respectively; p = 0.002). CONCLUSIONS Increasing the authenticity of instructional formats does not appear to significantly improve clinical reasoning performance in a pre-clerkship course. Medical educators should balance increases in authenticity with factors such as cognitive load, subject area and learner experience when designing new instructional formats. [ABSTRACT FROM AUTHOR]

School-based risk behavior surveys traditionally have been administered via paper-and-pencil. This study assessed the feasibility of conducting in-class online surveys in US high schools. A paper-and-pencil questionnaire assessing computer availability and perceptions of online surveys was mailed to a nationally representative sample of public and private high school principals in fall 2008. Completed surveys were returned by principals from 580 of 704 selected schools. Prevalence and 95% confidence intervals were computed. Most high schools have at least 1 computer lab, most computers in computer labs are connected to the Internet, and just under half of schools with a stationary computer lab had a sufficient number of computers to accommodate an in-class online survey administration. The 2 most common problems associated with online surveys were logistics of providing enough computers for an entire class and rotating classes into computer labs. Nearly two thirds of principals preferred online to paper-and-pencil surveys when administered to 4 randomly selected classes that met at different times during the school day, but less than half reported this preference when administered to 4 randomly selected classes that met at the same time during the school day. Many schools do not have sufficient computer capacity to participate in a voluntary in-class online survey. An online survey could impose significant perceived and actual burden on schools and therefore could result in unacceptably low school participation rates. Online administration for in-class surveys of students in US high schools are not recommended. [ABSTRACT FROM AUTHOR]

We submit newly developed citation impact indicators based not on arithmetic averages of citations but on percentile ranks. Citation distributions are-as a rule-highly skewed and should not be arithmetically averaged. With percentile ranks, the citation score of each paper is rated in terms of its percentile in the citation distribution. The percentile ranks approach allows for the formulation of a more abstract indicator scheme that can be used to organize and/or schematize different impact indicators according to three degrees of freedom: the selection of the reference sets, the evaluation criteria, and the choice of whether or not to define the publication sets as independent. Bibliometric data of seven principal investigators (PIs) of the Academic Medical Center of the University of Amsterdam are used as an exemplary dataset. We demonstrate that the proposed family indicators [ R(6), R(100), R(6, k), R(100, k)] are an improvement on averages-based indicators because one can account for the shape of the distributions of citations over papers.

Objective Little is known about rural-urban cancer disparities, particularly in South Korea, and this study is to identify cancer-specific mortality inequalities between the rural and urban areas of the country. Design, setting, and participants For 11 specific cancer sites, age-standardised mortality rates were analysed for the rural and urban administrative districts of South Korea during 2006-2011. Main outcome measures The Poisson log linear regression models were employed to estimate cancer-specific mortality rates, and Bonferroni comparison method was used to identify rural-urban disparities. Results There were significant rural-urban disparities observed for all cancer sites except prostate, pancreas and leukaemia. The mortality rates of lung, liver and stomach cancers, the three most common cancers in the country, were observed to be significantly higher in rural areas than in metropolitan areas. In contrast, the reverse relationship was observed for the reproductive system (breast and uterus) and colon cancers. Central nervous system cancer mortality was observed to be significantly higher in rural areas than in non-metro urban areas. Conclusions For the first time ever, significant rural-urban disparity patterns in cancer mortality rates in South Korea have been identified in this paper. Future investigations on cancer risk factors for the country should address these disparity patterns. [ABSTRACT FROM AUTHOR]
