Healthcare‐associated infections (HAIs) are a global public health threat. Italy is one of the countries with the highest prevalence of HAI. Hand hygiene (HH) is a pillar of infection prevention and control. Monitoring HH is necessary to improve HH compliance, and direct observation is considered the gold standard. Transcription and analysis of data collected during direct observation of HH compliance with the WHO paper form are time‐consuming. We collected, during a 9‐day observation period, HH opportunities and compliance both with a smartphone application (SpeedyAudit) and with the WHO paper form. Then, we investigated the difference in the required time for data transcription and analysis between the WHO paper form and the use of the app. The difference in the required time for data transcription and analysis was significant with a mean time of 2 s using the app and about 14–54 min/day using paper form (p =.004) while no significant difference was found in measured compliance rates between the two data collecting methods. HH monitoring with an app is time‐saving, and the app we used was easy to use. [ABSTRACT FROM AUTHOR]

BACKGROUND: Since the inception of the Youth Risk Behavior Surveillance System in 1991, all surveys have been conducted in schools, using paper and pencil instruments (PAPI). For the 2019 YRBSS, sites were offered the opportunity to conduct their surveys using electronic data collection. This study aimed to determine whether differences in select metrics existed between students who completed the survey electronically versus using PAPI. METHODS: Thirty risk behaviors were examined in this study. Data completeness, response rates and bivariate comparisons of risk behavior prevalence between administration modes were examined. RESULTS: Twenty‐nine of 30 questions examined had more complete responses among students using electronic surveys. Small differences were found for student and school response rates between modes. Twenty‐five of 30 adolescent risk behaviors showed no mode effect. CONCLUSIONS: Seven of 44 states and DC participated electronically. Because survey data were more complete; school and student response rates were consistent; and minor differences existed in risk behaviors between modes, the acceptability of collecting data electronically was demonstrated.

In recent years, the relationship of collaboration among scientists and the citation impact of papers have been frequently investigated. Most of the studies show that the two variables are closely related: An increasing collaboration activity (measured in terms of number of authors, number of affiliations, and number of countries) is associated with an increased citation impact. However, it is not clear whether the increased citation impact is based on the higher quality of papers that profit from more than one scientist giving expert input or other (citation-specific) factors. Thus, the current study addresses this question by using two comprehensive data sets with publications (in the biomedical area) including quality assessments by experts (F1000Prime member scores) and citation data for the publications. The study is based on more than 15,000 papers. Robust regression models are used to investigate the relationship between number of authors, number of affiliations, and number of countries, respectively, and citation impact-controlling for the papers' quality (measured by F1000Prime expert ratings). The results point out that the effect of collaboration activities on impact is largely independent of the papers' quality. The citation advantage is apparently not quality related; citation-specific factors (e.g., self-citations) seem to be important here. [ABSTRACT FROM AUTHOR]

To date, heat conduction from heat sources to tissue has been estimated by complex mathematical modeling. In the present study, we developed an intuitive in vitro skin burn model that illustrates heat conduction patterns inside the skin. This was composed of tightly compressed thermal papers with compression frames. Heat flow through the model left a trace by changing the color of thermal papers. These were digitized and three-dimensionally reconstituted to reproduce the heat conduction patterns in the skin. For standardization, we validated K91HG-CE thermal paper using a printout test and bivariate correlation analysis. We measured the papers' physical properties and calculated the estimated depth of heat conduction using Fourier's equation. Through contact burns of 5, 10, 15, 20, and 30 seconds on porcine skin and our burn model using a heated brass comb, and comparing the burn wound and heat conduction trace, we validated our model. The heat conduction pattern correlation analysis (intraclass correlation coefficient: 0.846, p < 0.001) and the heat conduction depth correlation analysis (intraclass correlation coefficient: 0.93, p < 0.001) showed statistically significant high correlations between the porcine burn wound and our model. Our model showed good correlation with porcine skin burn injury and replicated its heat conduction patterns. [ABSTRACT FROM AUTHOR]

Matrix population models (MPMs), which describe the demographic behaviour of a population based on age or stage through discrete time, are popular in ecology, evolutionary biology and conservation biology. MPMs provide a tool for guiding management decisions and can give insight into life history trade‐offs, patterns of senescence, transient dynamics and population trajectories. These models are parameterised with estimates of demographic rates (e.g. survival and reproduction) and can have multiple layers of underlying statistical analyses, all of which introduce uncertainty. For accurate and transparent results, this uncertainty should be propagated through to quantities derived from the MPMs, such as population growth rates (λ). However, full propagation is not always achieved, leading to omitted uncertainty and negative consequences for the reliability of inferences drawn.We summarised the contemporary standards regarding demographic rate uncertainty reporting and propagation, by reviewing papers using MPMs from 2010 to 2019. We then used reported uncertainties as the basis for a simulation study to explore the impact of uncertainty omission on inferences drawn from the analysis of MPMs. We simulated four scenarios of demographic rate propagation and evaluated their impact on population growth rate estimates.Although around 78% of MPM papers report some kind of uncertainty in their findings, only half of those report uncertainty in all aspects. Additionally, only 31% of papers fully propagate uncertainty through to derived quantities. Our simulations demonstrate that, even with moderate levels of uncertainty, incomplete propagation introduces bias. Omitting uncertainty may substantially alter conclusions, particularly for results showing small changes in population size. Biased conclusions were most common when uncertainty in the most influential demographic rates for population growth were omitted.We suggest comprehensive guidelines for reporting and propagating uncertainty in MPMs. Standardising methods and reporting will increase the reliability of MPMs and enhance the comparability of different models. These guidelines will improve the accuracy, transparency and reliability of population projections, increasing our confidence in results that can inform conservation efforts, ultimately contributing to biodiversity preservation.

Researchers need maps to effectively navigate increasingly voluminous literatures. This is no less the case in the field of problem structuring methods (PSMs). This paper offers an atlas of the journal literature of the theoretical development of, what are currently acknowledged to be, the four main PSMs up to their consolidation in 1989. A thorough contextual appreciation of the structure and dynamics of this literature sets the stage for addressing some of its specific aspects, for which an atlas is especially effective as an orientation device. Substantiated suggestions for exploratory excursions, as well as potential pitfalls, are accentuated, the overall aim being to provide researchers with navigational support that may assist their research objectives. Based on evidence uncovered from the atlas, a number of issues current in the PSM field are discussed, including the use of the collective descriptor 'family', the extent to which PSMs find their origins, and belong, in the wider field of operational research and the identification of sources that have hitherto received little or no acknowledgment but which merit attention as precursors and promising contributors to PSM research. The paper is accompanied by an electronic supplement containing the basic data of the atlas from which additional maps may be designed and constructed. [ABSTRACT FROM AUTHOR]

Background: Existing evidence suggests that clinician and organization engagement in research can improve healthcare processes of care and outcomes. However, current evidence has considered the relationship across all healthcare professions collectively. With the increase in allied health clinical academic and research activity, it is imperative for healthcare organizations, leaders and managers to understand engagement in research within these specific clinical fields. This systematic review aims to identify the effect of engagement in research by allied health professionals (AHPs) and organizations on healthcare performance. Methods: This systematic review has a two‐stage search strategy. The first stage will be to screen a previous systematic review examining the effectiveness of engagement in research in health and social care to identify relevant papers published pre‐2012. The search strategy used in the previous review will then be rerun, but with a specific focus on allied health. This multi‐database search will identify publications from 2012 to date. Only studies that assessed the effectiveness of allied health engagement in research will be included. All stages of the review will be conducted by two reviewers independently, plus documented discussions with the wider research team when discrepancies occur. This systematic review protocol follows the EQUATOR reporting guidelines of the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses for Protocols (PRISMA‐P). Discussion: The findings of this review will make a significant contribution to the evidence base around the effect of allied health engagement in research on healthcare performance. It will provide insights for clinicians and managers looking to understand the consequences of developing AHP research capability and capacity. The findings of this review will also aim to make recommendations for future evaluation approaches for engagement in research interventions. Trial registration: This systematic review protocol has been registered with PROSPERO, registration number CRD42021253461. What this paper adds: What is already known on the subject: This study will provide valuable evidence for professionals and policymakers seeking to understand engagement in research in the allied health disciplines. Where supported by the data, there may be recommendations for future research regarding specific variables to be considered when planning and evaluating engagement in research in allied health practice. What this paper adds to existing knowledge: A previous systematic review identified a positive association between clinician and organization engagement in research and improved processes of care and health outcomes. The reviews' findings have been used as a justification for clinicians and organizations to increase research capacity. That review evaluated literature published before 2012 and the studies that were identified predominantly reported on engagement in research by medics and nurses. An updated review is now required to include research published since 2012. This review will specifically focus on the effect of engagement in research within allied health disciplines. What are the potential or actual clinical implications of this work?: Research activity among AHPs is gaining momentum. Given this growth in AHP research activity and the rise in dedicated clinical academic roles, a contemporary review to identify the specific effect of AHP engagement in research on healthcare performance is prudent. The findings will inform clinicians, clinical managers and leaders of the potential impact of research activities by AHP clinicians and organizations. This will support the planning and development of initiatives focused on research capacity, capability and culture within allied health. [ABSTRACT FROM AUTHOR]

Aim: Bayesian statistical methods can allow for more complete and accurate incorporation of evidence in meta‐analyses. However, these methods remain under‐utilized. Methods: A scoping review was conducted to examine the proportion of biomedical meta‐analyses that used Bayesian methods in the period 2005–2016. The review also examined the reproducibility of the work, the cited sources, the reasons for it, its success or failure, the type of model and prior distributions, and whether a mixture of Bayesian and frequentist methods were employed. Results: We found that 1% of meta‐analyses are Bayesian and that the reporting and conduct of these were often poor. Data were published in 41% of analyses, and programs to run the analysis in 18%. Network meta‐analysis was the most common reason and became increasingly popular in recent years. In the majority of papers, models and distributions were either not reported or explained in such brief and ambiguous terms as to be uninformative. Conclusions: More use needs to be made of Bayesian meta‐analysis, and reporting needs to be improved. Greater awareness of these methods and access to training in them is essential.

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]

Generally, service interactions in dynamic environments comprising cloud computing, Internet of Things (IoT), and etc. occur in an unspecified situation causing trust management a significant aspect. The widespread usage of services in today's vastly high‐tech world reveals the rising necessity of trust management in terms of services. In dynamic environments, there are not enough confidences for users to recognize trustworthy service providers. Hence, evaluating and managing the trustworthiness of services is a vital challenge for enabling customers to select trustworthy resources in dynamic environments. To the extent of our knowledge, in spite of the vital role of Trust Management of Services (TMoS), there is not any thorough and systematic work in this scope with a specific focus on services. Thus, this research investigates the current methods of trust management in terms of services, which are published up to February 2020. We have identified 68 papers that are diminished to 22 mostly qualified papers through the article selection process. Also, we have examined and compared the selected papers in terms of their merits and demerits, considering the important parameters in this field. The investigation results point out that the security, scalability, and dynamicity are essential to almost all research. Furthermore, privacy and reliability are the most essential parameters in the field of TMoS. Moreover, the statistical results and information can contribute to future works; also, we have conducted some open issues and future work suggestions that could be an effective roadmap for future researchers in this area.

High resolution and high refresh rate increase the pressure of wide transmission. Usually, video compression is used to solve this problem. However, traditional video compression methods cannot be performed in bit‐plane, which will increase the cost of storage area. For this reason, this paper first introduces a bit just noticeable difference (BJND) model based on bit‐plane. By analyzing the relationship between the bit‐plane, frequency and eccentricity, the bit just noticeable difference threshold of viewpoint is calculated. Finally, the just noticeable difference model applied to bit‐plane is obtained. Then this paper proposes a video compression scheme based on bit motion estimation algorithm, which optimizes the search range of motion estimation into two small rhombuses of time dimension and gray‐scale dimension. According to human visual system and probability statistical analysis, supplementary matching blocks are added to replace residual data, so that the compression ratio will be constant. The experimental results show that the proposed scheme has the best comprehensive effect on the compression of the lower five‐bit plane. The compression ratio is 1.385, the data transmission is constant, and there is no obvious difference between the restored image and the original image, which conforms to the intuitive perception of the human eye.

Objective: To evaluate the impact of early treatment and IL1RN genetic variants on the response to anakinra in systemic juvenile idiopathic arthritis (JIA). Methods: Response to anakinra was defined as achievement of clinically inactive disease (CID) at 6 months without glucocorticoid treatment. Demographic, clinical, and laboratory characteristics of 56 patients were evaluated in univariate and multivariate analyses as predictors of response to treatment. Six single‐nucleotide polymorphisms (SNPs) in the IL1RN gene, previously demonstrated to be associated with a poor response to anakinra, were genotyped by quantitative polymerase chain reaction (qPCR) or Sanger sequencing. Haplotype mapping was performed with Haploview software. IL1RN messenger RNA (mRNA) expression in whole blood from patients, prior to anakinra treatment initiation, was assessed by qPCR. Results: After 6 months of anakinra treatment, 73.2% of patients met the criteria for CID without receiving glucocorticoids. In the univariate analysis, the variable most strongly related to the response was disease duration from onset to initiation of anakinra treatment, with an optimal cutoff at 3 months (area under the curve 84.1%). Patients who started anakinra treatment ≥3 months after disease onset had an 8‐fold higher risk of nonresponse at 6 months of treatment. We confirmed that the 6 IL1RN SNPs were inherited as a common haplotype. We found that homozygosity for ≥1 high‐expression SNP correlated with higher IL1RN mRNA levels and was associated with a 6‐fold higher risk of nonresponse, independent of disease duration. Conclusion: Our findings on patients with systemic JIA confirm the important role of early interleukin‐1 inhibition and suggest that genetic IL1RN variants predict nonresponse to therapy with anakinra.

Background: The use of e‐exams in higher education is increasing. However, the role of student diversity in the acceptance of e‐exams is an under‐researched topic. In the current study, we considered student diversity in terms of three sociodemographic characteristics (age, gender, and second language) and three dispositional student characteristics (computer anxiety, test anxiety, and technology openness). Objectives: The main objective of this study was to investigate the relationship between student diversity and acceptance of e‐exams. Methods: Our research combined cross‐sectional analyses (N = 1639) with data from a natural experiment on the introduction of e‐exams versus the established paper‐pencil exams (N = 626) and used both self‐report and institutional data. Sociodemographic and dispositional characteristics were indirectly related to pre‐exam acceptance via expectancy variables from the Technology Acceptance Model framework. Results and Conclusions: Comparisons of post‐exam acceptance showed that practical experience with the e‐exam led to a significant increase in e‐exam acceptance, and that students with low openness toward technology particularly benefited from this effect. Students' exam performance (i.e., grades) was unrelated to the exam format or their pre‐exam acceptance of the e‐exam format, and this was true across students' sociodemographic and dispositional characteristics. Takeaway: Student diversity plays a role in e‐exam acceptance, but its influence is mitigated by first‐hand experience with e‐exams. The practical implications for higher education institutions aiming to implement e‐exams are discussed. Lay Description: What is already known about this topic: The use of e‐exams in higher education is increasingThe role of student diversity for e‐exam acceptance is unclearTechnology acceptance is predicted by expectancies towards new system What this paper adds: We investigated students' sociodemographic and dispositional diversityDiversity predicted e‐exam acceptance via the expectanciesIn a natural experiment, first‐hand experience increased e‐exam acceptanceNo difference between performance in e‐exams and paper‐pencil‐exams found Implications of the study findings for practitioners: Higher education institutions implementing e‐exams should consider diversitySupport for older students and students with low technology openness neededNo student groups systematically disadvantaged by e‐exam implementationPractice rooms can increase experience with new system before exam [ABSTRACT FROM AUTHOR]

During the past few decades, the rate of publication retractions has increased dramatically in academia. In this study, we investigate retractions from a quantitative perspective, aiming to answer two fundamental questions. One, how do retractions influence the scholarly impact of retracted papers, authors, and institutions? Two, does this influence propagate to the wider academic community through scholarly associations? Specifically, we analyzed a set of retracted articles indexed in Thomson Reuters Web of Science (WoS), and ran multiple experiments to compare changes in scholarly impact against a control set of nonretracted articles, authors, and institutions. We further applied the Granger Causality test to investigate whether different scientific topics are dynamically affected by retracted papers occurring within those topics. Our results show two key findings: first, the scholarly impact of retracted papers and authors significantly decreases after retraction, and the most severe impact decrease correlates with retractions based on proven, purposeful scientific misconduct; second, this retraction penalty does not seem to spread through the broader scholarly social graph, but instead has a limited and localized effect. Our findings may provide useful insights for scholars or science committees to evaluate the scholarly value of papers, authors, or institutions related to retractions. [ABSTRACT FROM AUTHOR]

Peer review is the backbone of modern science. F1000Prime is a postpublication peer review system of the biomedical literature (papers from medical and biological journals). This study is concerned with the interrater reliability and convergent validity of the peer recommendations formulated in the F1000Prime peer review system. The study is based on about 100,000 papers with recommendations from faculty members. Even if intersubjectivity plays a fundamental role in science, the analyses of the reliability of the F1000Prime peer review system show a rather low level of agreement between faculty members. This result is in agreement with most other studies that have been published on the journal peer review system. Logistic regression models are used to investigate the convergent validity of the F1000Prime peer review system. As the results show, the proportion of highly cited papers among those selected by the faculty members is significantly higher than expected. In addition, better recommendation scores are also associated with higher performing papers. [ABSTRACT FROM AUTHOR]

Statistics can be intimidating for clinicians and reviewers. Statistics are often important and useful but can mislead. Elaborate statistics can support conclusions that contradict clinical experience. This article explores some statistically related insights. Statistical reasons for rejecting papers were collated, and the frequency and complexity of statistical tests in accepted, published papers in otolaryngology journals were then studied. Most statistical errors in papers are logical misinterpretations of information rather than lack of understanding of statistics. Otolaryngology papers tend to employ relatively straightforward statistics that should be useful for clinicians. Although evidence-based medicine has changed medical publishing, clinical knowledge is more important that statistical knowledge for clinical applications of statistics. [ABSTRACT FROM AUTHOR]

Given the popularity of Big Data (BD), there can be an impression that fields such as design of experiments (DOE) are now irrelevant. We would like to thank the authors for starting the conversation about the possible relationship between these two fields. A key contribution of this paper is in showing how DOE principles, as summarized under the name designed data collection (DDC), can be applied throughout the BD process. This name is quite appropriate, demonstrating that these principles apply not just to designed experiments, but to any form of data collection. This is especially important for situations where designed experiments are either impossible (i.e., assessing how a country's economy may impact certain responses) or unethical (i.e., certain sensitive types of medical studies). It shows that DOE is more than a particular choice of design type, but is rather a methodology for approaching data collection. One that seeks to extract the most relevant information from the data while also taking into account the various nuances and constraints of physical and social processes, which are ever present, even in massive datasets. The paper divides BD efforts into three general phases: Before BD, During BD, and After BD. As such, we have grouped our discussion accordingly, with general comments provided for the suggested contributions of DDC in each phase. We then close with some additional thoughts.

The article discusses the common statistical errors seen in published scientific studies or review papers. It highlights the two of the myriad problems identified in science reporting such as the misuse of statistics and the overinterpretation of data. The most often used statistical tests seen in the medical literature are also explored including the t-test and Chi-square test.

The aim of this paper is to extend our knowledge about the power-law relationship between citation-based performance and coauthorship patterns in papers in the natural sciences. We analyzed 829,924 articles that received 16,490,346 citations. The number of articles published through coauthorship accounts for 89%. The citation-based performance and coauthorship patterns exhibit a power-law correlation with a scaling exponent of 1.20 ± 0.07. Citations to a subfield's research articles tended to increase 2.1.20 or 2.30 times each time it doubled the number of coauthored papers. The scaling exponent for the power-law relationship for single-authored papers was 0.85 ± 0.11. The citations to a subfield's single-authored research articles increased 2.0.85 or 1.89 times each time the research area doubled the number of single-authored papers. The Matthew Effect is stronger for coauthored papers than for single-authored. In fact, with a scaling exponent <1.0 the impact of single-authored papers exhibits a cumulative disadvantage or inverse Matthew Effect. [ABSTRACT FROM AUTHOR]

Varietal studies of sedimentary provenance use the properties of individual minerals or mineral groups. These are recorded as lists of numerical tables that can be difficult to interpret. Multidimensional Scaling (MDS) is a popular multivariate ordination technique for analyzing other types of provenance data based on, for example, detrital geochronology or petrography. Applying MDS to varietal data would allow them to be treated on an equal footing with those other provenance proxies. MDS requires a method to quantify the dissimilarity between two samples. This paper introduces three ways to do so. The first method ("treatment‐by‐row") turns lists of (compositional) data tables into lists of vectors, using principal component analysis. These lists of vectors can then be treated as "distributional" data and subjected to MDS analysis using dissimilarity measures such as the Kolmogorov‐Smirnov statistic. The second method ("treatment‐by‐column") turns lists of compositional data tables into multiple lists of vectors, each representing a single component of the varietal data. These multiple distributional data sets are subsequently subjected to Procrustes analysis or 3‐way MDS. The third method uses the Wasserstein‐2 distance to jointly compare the rows and columns of varietal data. This arguably makes the best use of the data but acts more like a "black box" than the other two methods. Applying the three methods to a detrital titanite data set from Colombia yields similar results. After converting varietal data to dissimilarity matrices, they can be combined with other types of provenance data, again using Procrustes analysis or 3‐way MDS. Plain Language Summary: The source of modern or ancient sediment can be determined by examining either the overall characteristics of the sediment or the chemical composition of individual sediment particles. With the help of recent analytical advancements, geologists can now analyze the complete chemical makeup of single grains of sand or silt. These types of data sets, known as "varietal" data sets, have the ability to uncover differences between sediments that are not visible through traditional methods. However, varietal data are incompatible with the statistical methods that geologists typically use to determine the origin of sediment. This paper addresses this issue by presenting three methods for quantifying the differences between varietal data sets, which is a crucial step in any further statistical analysis. Testing these methods on a varietal data set from Colombia shows similar outcomes. By using the techniques described in this paper, varietal data can now be combined with other conventional methods for determining sediment origin. Key Points: Varietal data are defined as lists of compositional tablesGiven an appropriate dissimilarity measure, varietal data can be subjected to multidimensional scalingThis paper introduces three ways to quantify the pairwise dissimilarity of varietal data [ABSTRACT FROM AUTHOR]

The adoption of Information and Communication Technologies in early childhood education is crucial for adapting traditional classrooms to the digital era. Over time, young children are increasingly using touch screen technologies such as tablets at home and in early childhood settings. However, the literature shows that there is a significant gap in knowledge of using this technology in early childhood education. Most researchers have focused on the pedagogical theory behind using touch screen devices, but there have not been many empirical studies about how these technologies affect students' learning processes. This paper presents three learning experiences where early childhood students perform educational activities using tablet computers, interactive whiteboards, and paper cards. The results show that students who used the technology were more motivated and achieved better results that those who used paper cards. Lay Description: What is already known about this topic: The use of ICT in childhood education offers new possibilities for teachers to provide new and more visual digital learning content to their students.Touch technologies seem suitable for young students. Because their motor skills are not fully developed yet, interacting with computers through a mouse and a keyboard is more difficult than doing it through natural gestures.There are many studies in higher education levels that demonstrate that proper use of ICT in education can lead to an increase of the students' motivation and learning. What this paper adds: Three empirical studies in three different childhood education classrooms to shed some light about how ICT can impact positively students learning.A comparison of interactive whiteboards and tablet computers benefits regarding more traditional methodologies in childhood education.Insights about how hardware and software can be combined to provide students a suitable learning environment in childhood education classrooms. Implications for practice and/or policy: Teachers should consider how they will create the workgroups. It is highly advisable to create heterogeneous groups taking into account the students' skills. This way, members of the same group can help each other, creating a richer learning scenario.Several teachers who participated in our studies said that they were not able to use ICT in their classrooms because they did not have enough digital competences. Our studies and the results obtained led them consider integrating technology in their classrooms. The good results obtained by the students who worked with technology changed the teachers' perspective about the use of technology in the classroom.Students showed a great interest in the use of tablet computers and interactive whiteboards, which translated into higher motivation compared with the students who solved the activities on paper.

Nowadays, academic journals of high standing rarely accept a conceptual idea in a paper not instantly accompanied by econometric estimates. The idea would almost certainly get rejected. Empirical validation based on past statistical data has produced an unfortunate backward orientation in economics. While one can learn from the past, this approach fails when the underlying conditions strongly change. The paper suggests various possibilities to overcome the intense publication pressure in so‐called top journals and the overemphasis on instant empirical evidence. Academia is, however, unlikely to adapt. As economics is too backward oriented, other disciplines or cranks may well dominate future economic policy. [ABSTRACT FROM AUTHOR]

Aim: This study investigated the scientific research ability of Chinese specialist nurses (SNs) in the Guangxi Zhuang Autonomous Region and its influencing factors. Design: A cross‐sectional design. Methods: A total of 652 SNs in the Guangxi Zhuang Autonomous Region were investigated from March to October 2021. The nursing scientific research ability level was measured using the Nursing Research Competence of Nurses Self‐evaluation Scale. Descriptive statistics, univariate analysis and ordinal logistic regression analysis were used to evaluate factors affecting the scientific research ability of SNs. Results: The median score of scientific research ability of SNs was 31 (interquartile range: 19–41). Approximately 74.8% of clinical speciality nurses had low scientific research ability. Educational background, working hospital level, being the first author of a published paper and successful application for scientific research projects were identified as factors influencing scientific research ability score.

Comprehensive Summary: Xylan is the most abundant hemicellulose in nature. As a new type of green organic solvent, ionic liquid shows good preservation ability for the functional groups of hemicellulose. In this paper, a single molecule detection technology based on glass nanopore was established to analyze xylan dissolved in ionic liquid. Arabino‐xylan (AX) and beech xylan (BX) are respectively taken as the representatives of heterogeneous xylan and homogeneous xylan. Firstly, unmodified glass nanopore was used to detect the dissolved xylan in ionic liquid, and then poly(ethylene imine) (PEI) was used to modify the nanopore to change the surface charge in the nanopore and further enhance the interaction between the nanopore and the xylan molecule. It was found that before and after nanopore modification, at negative voltage and low positive voltage, AX didn't generate current blocking signal. On the contrary, BX didn't generate current blocking signal at positive voltage. This phenomenon may be due to the current disturbance driven by electrophoresis and electroosmosis of xylan molecules with weak negative charge. After statistics analysis, the current blocking signal of AX showed that the modified nanopore showed multiple peaks. It indicates that heterogeneous xylan and PEI modified nanopore had stronger interaction. The results show that the nanopore detection technology can show the structural difference of heterogenous branched chain and homogeneous straight chain based on the single characteristic current blocking signal and statistical information, providing a research basis for the structural analysis of water insoluble polysaccharides.

Rationale, aims and objectives Understanding the impact of health information technology on doctor-patient interaction is vital to designing better electronic health records ( EHRs). This article quantitatively examines and compares clinically experienced physicians' interactions with patients using paper or EHRs in ambulatory primary care settings. Methods Clinical encounters using paper or EHRs were recorded with high-resolution video cameras to capture physicians' interactions with the health records and patients. All videos were coded using quantified video coding methodology to understand how physicians interacted with EHRs and patients through measuring eye gaze durations. Statistical analysis was conducted to compare the results of the paper and EHR visits. Results Eight experienced family medicine physicians and 80 patients participated in the study. A total of 80 visits, 40 with paper and 40 with EHRs were recorded. The proportion of time physicians spent gazing at medical records during EHR visits was significantly more than in paper chart visits (35.2 versus 22.1%, P = 0.001). A significantly smaller proportion of physician time was spent gazing at the patient when using an EHR compared with when using a paper chart (52.6 versus 45.6%, P = 0.041). Conclusions For this group of family medicine physicians, more time was spent looking at the EHR screen than paper records and a little less time looking at the patient.

ABSTRACT In digital healthcare engineering (DHE) for aging monopile‐type offshore wind turbines, predictive health analysis is essential for robust future maintenance planning. This paper presents the development of a DHE module for the predictive health analysis of corroded monopile‐type offshore wind turbines, focusing on wind and rotor blade rotation effects. An empirical formula for predicting time‐variant corrosion wastage is derived from a statistical analysis of a decade‐long corrosion wastage database and applied to predict the corrosion depth of a 5 MW monopile‐type offshore wind turbine, serving as an illustrative example. Nonlinear finite element analyses using LS‐DYNA are performed on the corroded turbine tower under combined wind‐induced loads and rotor‐induced thrust forces. Two types of corrosion wastage, pitting, and uniform (general) corrosion, are considered. The health condition of the corroded tower is evaluated based on serviceability limit state and ultimate limit state criteria. The methodology developed in this paper will be integrated into the DHE system currently being developed by the authors for aging monopile‐type offshore wind turbines. [ABSTRACT FROM AUTHOR]

Background: Instructional videos constitute a pivotal component in flipped learning. Despite their significance, there is a dearth of research specifically dedicated to instructional videos within the context of flipped classrooms. This paucity has led to an empirical void in verifying the efficacy of instructional videos in flipped learning environments. Objectives: The present study endeavours to contribute to the extant literature on flipped pedagogical practices by providing empirical evidence regarding the effectiveness of instructional videos in flipped learning environments. Methods: This study employs a convergent mixed‐methods design. Forty‐five instructional videos in three subtypes were administered in two classes over a 15‐week semester. Data, both quantitative (log data from the learning management system) and qualitative (from focus group discussions at two time points), were concurrently collected from a flipped class (n = 25) and a blended class (n = 28) with the aim of gauging student engagement and learning outcomes in the flipped class and understanding video‐viewing features typical of the flipped class. Results: Both datasets corroborated that participants in the flipped class outperformed their counterparts in the blended class in terms of video‐watching, peer interaction, knowledge retention, and transfer skills. Conclusions: The instructional videos within the flipped classroom setting serve to enhance student engagement in the learning process and improve learning outcomes. The efficacy of these instructional videos in flipped learning can be further augmented through strategic approaches in both their design and implementation. Lay Description: What is currently known about this topic: The flipping pedagogy is conducive to learning.Videos play a crucial role in flipped learning.Videos prepared students for classroom activities.However, engaging students with pre‐class videos presents a challenge. What this paper adds: This paper furnishes direct empirical evidence supporting the effectiveness of instructional videos in flipped learning.It uncovers factors affecting student engagement with videos in flipped learning.It offers insights into the design and implementation of videos in flipped learning. Implications for practice: Considering facilitating conditions and affective factors when creating videos.Acknowledging learner characteristics when designing videos.Utilizing instructional strategies when implementing videos.

Background: Mindfulness practices enhance executive function skills and academic achievement, spurring interest in integrating mindfulness interventions into education. Embedding mindfulness practice into a digital math game may provide a low‐cost, scalable way to induce mindfulness and boost game‐based learning, yet this approach remains unexplored. Objectives: We investigated the learning benefits of integrating mindfulness exercises in a digital math learning game and examined how students' trait mindfulness might moderate the outcomes. Methods: Two classroom studies were conducted with 404 5th and 6th grade students from six public schools in the U.S. (nStudy 1 = 227, nStudy 2 = 177). The two randomized controlled experiments assigned students to one of the three conditions: passive control (playing the digital learning game Decimal Point), story‐enriched active control, or mindfulness‐enriched condition. Trait mindfulness, learning gains, and in‐game problem‐solving (including problem‐solving duration, error count and correctness after reminder) were assessed. Study 2 included a manipulation check to better understand the effects of the mindfulness intervention. Results: Findings showed no significant differences in learning gains, problem‐solving duration or error count among the conditions. Students' trait mindfulness did not moderate these outcomes. Mindfulness reminders in the mindfulness‐enriched game led to more correct answers after errors than jokes in the story‐enriched game. Study 2 revealed that we failed to induce higher state mindfulness through the mindfulness inductions. Conclusions: Mindfulness prompts could be especially beneficial for students experiencing frustration during gameplay, warranting more exploration for digital game‐based instruction. We highlight barriers and future directions for fostering mindfulness through computer‐based instruction in classrooms. Lay Description: What is currently known about this topic?: Researchers focus on digital games as productive learning environments for math, with potential for higher learning gains compared with traditional methods. However, results are mixed, and not all games lead to improved math outcomes.Executive function (EF) skills are crucial for math learning, and mindfulness‐based interventions show promise in enhancing EF skills in school‐aged students.Embedding mindfulness practice into a digital math game may provide a low‐cost, scalable way to induce mindfulness and, in turn, boost EF skills and game‐based learning, yet this approach remains unexplored What does this paper add?: This paper presents the results of two randomized control trials investigating the feasibility and benefits of incorporating mindfulness exercises into a digital math game designed for middle school students. Benefits are compared to those of a story‐enriched and regular version of the same digital math learning game.The paper also explores variations in the effects of the mindfulness‐enriched game based on students' initial trait mindfulness levels.We observe that listening to mindfulness inductions at the beginning of game sessions do not induce mindfulness, and therefore does not benefit math learning.We find that mindfulness prompts received after recurrent errors can be beneficial for students' problem solving. Implications of study findings for practitioners: Our study provides important information on how digital learning game designers should attempt to induce mindfulness in a digital game to promote learning.Digital learning game designers should consider incorporating mindfulness exercises into their games strategically. Presenting mindfulness inductions in audio format at the beginning of game sessions may not induce mindfulness or benefit math learning. Instead, designers should focus on integrating mindfulness prompts at moments when students encounter frustration within the learning game.Beyond embedding audio mindfulness exercises in the game, learning designers should also consider alternative technological and game features to induce mindfulness within a learning game.

Background: Learner profiles detected from digital trace data are typically triangulated with survey data to explain those profiles based on learners' internal conditions (e.g., motivation). However, survey data are often analysed with limited consideration of the interconnected nature of learners' internal conditions. Objectives: Aiming to enable a thorough understanding of trace‐based learner profiles, this paper presents and evaluates a comprehensive approach to analysis of learners' self‐reports, which extends conventional statistical methods with psychological networks analysis. Methods: The study context is a massive open online course (MOOC) aimed at promoting physical activity (PA) for health. Learners' (N = 497) perceptions related to PA, as well as their self‐efficacy and intentions to increase the level of PA were collected before and after the MOOC, while their interactions with the course were logged as digital traces. Learner profiles derived from trace data were further examined and interpreted through a combined use of conventional statistical methods and psychological networks analysis. Results and Conclusions: The inclusion of psychological networks in the analysis of learners' self‐reports collected before the start of the MOOC offers better understanding of trace‐based learner profiles, compared to the conventional statistical analysis only. Likewise, the combined use of conventional statistical methods and psychological networks in the analysis of learners' self‐reports before and after the MOOC provided more comprehensive insights about changes in the constructs measured in each learner profile. Major Takeaways: The combined use of conventional statistical methods and psychological networks presented in this paper sets a path for a comprehensive analysis of survey data. The insights it offers complement the information about learner profiles derived from trace data, thus allowing for a more thorough understanding of learners' course engagement than any individual method or data source would allow. Lay Description: What is already known about this topic: Researchers have made extensive use of data from online learning platforms—often referred to as learning trace data—to understand how learners engage in online learning activities.Surveys are often used to gather information about learners' motivation, perceptions, and other internal factors, to complement the insight gleaned from learning traces and thus create a more complete picture of the learning behaviour.When analysing survey data, the focus is usually on individual factors without considering how different factors are connected and affect one another.Psychological networks analysis is a novel analytic approach to studying complex phenomena both in psychology and education. What this paper adds: The paper uses psychological networks as a method for examining mutual relations among learners' internal factors (e.g., motivation, perceptions) measured through self‐reports before and after a course.By combining conventional statistical analysis of self‐reports with psychological networks analysis, the paper develops a comprehensive picture of learners' internal factors measured through self‐reports, one that accounts for both individual and interconnected nature of those factors.This comprehensive approach to information extraction from surveys allows for better understanding of trace‐based learner profiles, that is, profiles mined from data about learners' interaction with online learning activities. Implications for practice and/or policy: The presented method paves a way for a comprehensive analysis of the data collected from learners through surveys.It helps us gain a better understanding of learners' engagement with online learning activities.It can advance the evaluation of digital educational programs that aim to encourage changes in health‐related behaviour.

Background: With the growing integration of technology in education, the adoption of blended learning (b‐learning) has gained attention. B‐learning combines traditional classroom teaching with online components, holding potential to enhance student outcomes and educational efficiency. Yet, current research predominantly concentrates on higher education institutions in urban areas, creating a void in understanding its impact on K‐12 education, particularly in rural settings. Objectives: This qualitative study aims to propose recommendations for successful implementation of blended learning in rural K‐12 areas by addressing the key stakeholders influencing its adoption and identifying the main factors affecting its success. Methods: We performed a content analysis of grey literature documents detailing the implementation of b‐learning in K‐12 education. Additionally, interviews with crucial stakeholders such as teachers, principals, and experts in rural schools in South America provide insights into the challenges and prospects of b‐learning adoption in these contexts. Results and Conclusions: The study identifies pivotal stakeholders for effective b‐learning implementation, outlining their roles and addressing challenges inherent in rural settings. Recommendations for enhancing b‐learning's implementation in developing countries are also proposed. The research underscores the significance of involving diverse stakeholders such as governmental bodies, school leaders, educators, students, and families to ensure a holistic and efficient approach to blended learning. Lay Description: What is currently known about this topic: Blended Learning Definition and Benefits: Blended learning combines face‐to‐face and online instruction, enhancing student engagement and personalization by providing diverse learning pathways.Growth in K‐12 Implementation: Blended learning gained traction in K‐12 education, boosting academic outcomes, driven by recognition of learner diversity and potential in meeting students' needs.Contextual Challenges: Implementation challenges arise in low‐income households and rural areas, including limited access to technology and internet connectivity, impacting student engagement and success. What does this paper add: Focusing on Rural Dynamics: This study helps to fill a gap by investigating blended learning in rural K‐12 settings, spotlighting key players and success drivers in these unique contexts.Recommendations from Various Sources: By combining interviews and grey literature, this research generates comprehensive, practical recommendations grounded in both empirical insights and real‐world perspectives.Insights into Rural Hurdles: This paper extends the discussion on blended learning by addressing specific rural barriers, proposing family involvement, private sector partnerships for training, and tailored pedagogical strategies. Implications for practice or policy: Leadership and Collaboration: Effective school leadership and collaboration with local governments are pivotal for fruitful blended learning implementation, ensuring defined roles, responsibility, and accountability.Adaptable Curriculum Design: An adaptable, centralized curriculum aligns with recommendations, fostering efficient tracking of student progress and enabling customized learning.Engagement‐Centric Pedagogies: Recommendations spotlight interactive, student‐centered teaching methods, tailored to diverse student needs, nurturing active participation and elevated learning outcomes.

Background: Painting is the foundational expression across all art forms and is one of the key creative practices for fostering students' aesthetic ability and creativity within fine arts courses. Collaborative painting in the form of socially shared regulation of learning (SSRL) can be recognized as an effective strategy for enhancing creativity in both individual and group work. However, the absence of contextual experiences and collaborative spaces poses challenges for students in cultivating their creativity in painting. Objectives: The present study explores students' creativity, socially shared regulation (SSR) and positive painting behaviours using an SSRL‐based collaborative painting approach in the metaverse (Meta‐CP). Methods: Via a quasi‐experimental design, a total of 40 Chinese students in fifth grade were recruited and were randomly divided into an experimental group and a control group, with 20 students utilizing the Meta‐CP approach, while the remaining 20 students followed the conventional SSRL‐based paper‐and‐brush collaborative painting (C‐CP) approach. The Meta‐CP approach not only offers an authentic painting context and a collaborative space but also facilitates the collaborative process through the SSRL framework. The data collection included students' creative tendency, painting works and painting process. Results and Conclusions: The Meta‐CP approach effectively enhances students' creativity concerning adventure, curiosity and imagination, as well as results in the creation of more distinctive and logical artistic works. Furthermore, the approach significantly improved the quality of students' SSR. Additionally, students utilizing the Meta‐CP approach displayed more positive painting behaviours compared with those employing the C‐CP approach. Lay Description: What is already known about this topic:Collaborative painting is an effective strategy for enhancing creativity.Socially shared regulation of learning (SSRL) fosters collaborative learning.Students in collaborative painting may lack a contextual and synchronized painting space.The metaverse benefits in terms of contextual experiences and collaborative spaces. What this paper adds:Using an SSRL‐based collaborative painting approach in the metaverse (Meta‐CP) is effective in improving students' creativity.The Meta‐CP approach has the potential to improve students' quality of socially shared regulation (SSR), and positive painting behaviours. Implications for practice and/or policy:The metaverse provides an immersive synchronized painting space for art education to stimulate students' creative potential.The metaverse with proper learning strategies (e.g., SSRL) provides an effective collaborative learning environment for creation.

This paper critically examines the normative versus non‐normative distinction commonly used in collective action research. To explore the similarities and differences between antecedents of normative versus non‐normative actions, we conducted a systematic review on diverse predictors of non‐normative, radical and violent collective actions. We examined 37 social and political psychology studies published after 2010 and identified five recurring themes: identity, efficacy, injustice, emotions and norms. Findings exhibited significant overlaps with those predictors associated with normative collective action. Thus, a reconceptualization is needed to undermine the rigid boundaries between these action types, highlighting the intricate interplay of factors that transcend the conventional binary. Aiming to avoid conceptual ambiguity and challenge the perspective that associating particular collective actions with unwarranted violence using social norms as fixed and a priori, we propose the term 'confrontational collective action' to separate out form of action from societal approval. Through this reconceptualization, we discussed the main limitations in the literature, focusing on how studies approach normativity and efficacy and addressing the issue of decontextualization in the literature. This paper calls for a contextually informed understanding of confrontational collective action that recognizes what is seen as 'normative' can change over time through intra‐ and intergroup interactions.

Aim: Evidence shows that 20%–30% of patients who aspirate do so silently. Research to date has not demonstrated clear evidence to indicate which patients are at higher risk of silent aspiration. Our aim was to use univariate logistic regression analysis of retrospective case review to determine potential patterns of silent aspiration. Materials and methods: We conducted a retrospective analysis of 455 fiberoptic endoscopic evaluation of swallowing (FEES) reports. The patients were divided into four groups: G1 – neurological diseases (n = 93), G2 – head and neck surgery (n = 200), G3 – gastroenterological diseases (n = 94) and G4 – other patients (n = 68). Data included the occurrence or absence of saliva penetration or aspiration, of silent fluid/solid food penetration or aspiration, type of penetration or aspiration, occurrence of cranial nerve paresis, radiotherapy and tracheostomy. Univariate logistic regression was used to evaluate independent risk factors of silent aspiration in the study population. Three models with different independent variables were considered. Results: There is a statistically significant difference in the frequency of occurrence of silent penetration and aspiration within the groups (p < 0.001), with intraglutative being most frequent. Fluid and food penetration and aspiration correlated with saliva penetration and aspiration in all groups (p < 0.001). Cranial nerve paresis (IX and X), radiotherapy and tracheostomy correlate with saliva penetration and aspiration (p = 0.020 for cranial nerve paresis; p = 0.004 for radiotherapy; p < 0.001 for tracheostomy). One hundred and fifteen patients (45.81%) in the subgroup of patients with intraglutative aspiration had cranial nerve paresis (IX, X or IX–X). Conclusions: Patients who should be prioritised or considered to be at a higher need of instrumental swallowing evaluation are those with IX and X cranial nerve paresis, tracheostomy and those who have had radiotherapy, with saliva swallowing problems, especially after paraganglioma, thyroid and parathyroid glands and middle and posterior fossa tumour surgery. WHAT THIS PAPER ADDS: What is already known on the subject: Clinical signs of penetration or aspiration include coughing, throat clearing and voice changes, while silent penetration or aspiration patients aspirate without demonstrating any clinical symptoms. The most common consequences of silent aspiration include aspiration pneumonia, recurrent lower respiratory tract infections and respiratory failure. Additionally, malnutrition and dehydration can be indicators of silent aspiration. Patients may unknowingly reduce their oral intake and lose weight. Retrospective studies have shown that 20%–30% of patients aspirate silently (e.g. patients after stroke, acquired brain injury, head and neck cancer treatment, prolonged intubation). Clinical examination of swallowing can miss up to 50% of cases of silent aspiration. What this paper adds to existing knowledge: Currently, silent aspiration is often discussed in neurological literature, but its applications to head and neck surgery are limited. In this study, we identify head and neck surgery patients who should be prioritised or considered to be in higher need of instrumental swallowing evaluation due to a higher risk of silent aspiration. What are the potential or actual clinical implications of this work?: Post‐treatment structural changes can result in lower cranial nerve paresis (IX, X, XII) and face injury, in which vagus and glossopharyngeal nerves are injured. After tracheostomy and radiotherapy, patients with problems swallowing saliva need careful clinical examination, particularly cranial nerve examination. [ABSTRACT FROM AUTHOR]

Background: Endovascular clot retrieval (ECR) is known to reduce global disability at 3 months post stroke however limited research exists regarding the trajectory of specific clinical impairments including language, swallowing and cognitive deficits between onset and 3 months. Aims: To assess language, swallowing, and cognitive performance following ECR and explore whether impairment severity is correlated with modified Thrombolysis in Cerebral Infarction score (mTICI), stroke severity or quality of life (QoL). Methods: Assessment was completed within 7 days (T1), 1 month (T2) and 3 months (T3) post‐stroke. Performance was measured with the Functional Oral Intake Scale (FOIS), Repeatable Battery for Assessment of Neuropsychological Status (RBANS), Trail Making Test (TMT A and B) and Brixton Spatial Awareness Test. The Western Aphasia Battery (WAB) was used for left hemisphere stroke. QoL was measured with the Stroke and Aphasia Quality of Life Scale. Results: Twenty‐five participants (median 72 years; 64% male) were prospectively recruited following ECR. High reperfusion success (68% mTICI 3) and low stroke severity post ECR (median 24 h NIHSS = 3, IQR 7–18) were noted. At T1, 10 participants presented with aphasia, eight required a modified diet and 20 had impaired cognition. At T3 all had recovered to a normal oral diet, 39% had persistent cognitive impairment and 45% of patients with left hemisphere stroke remained aphasic. Performance on the WAB, FOIS, RBANS and TMT changed significantly over time (all p < 0.05). The severity score at T1 for all measures, excluding TMT B and Brixton, was significantly correlated with 24 h NIHSS. WAB scores at T3 were correlated with QoL (r = 0.618; p = 0.043). Conclusion: This exploratory study found the longitudinal performance of language, swallowing and cognition significantly improved over time and severity in the first‐week post‐ECR was correlated with 24 h NIHSS rather than the degree of reperfusion. WHAT THIS PAPER ADDS: What is already known on the subject: Randomised control trials have demonstrated the benefit of ECR in patients with ischemic stroke using global measures of disability and function. Limited research exists regarding the trajectory of specific clinical impairments including language, swallowing and cognitive deficits. There is also a reliance on screening assessments and a lack of consideration of the influence of co‐occurring impairments. What this paper adds to existing knowledge: This prospective study is amongst the first to explore the longitudinal trajectory of language, swallowing and cognitive impairment using a standardised assessment battery. Twenty‐four‐hour NIHSS was significantly correlated with language, swallowing, global cognition and some measures of executive function. Language performance post ECR was correlated with domain‐specific cognitive assessment of attention, immediate memory and delayed memory, which differed from swallowing performance post ECR that correlated with measures of executive function. What are the potential or actual clinical implications of this work?: It is important for speech‐language pathologists and the wider medical team to monitor language, swallowing and cognitive performance post ECR regardless of treatment success. Stroke severity at 24 h post‐ECR influences the severity of language, swallowing and cognitive impairments. [ABSTRACT FROM AUTHOR]

Background: Pictures drawn by people with aphasia (PWA) are often more challenging to understand than those drawn by healthy people. There are two types of objects: those that tend to be drawn symbolically (symbolically drawn objects—SOs) and those that are likely to be drawn realistically (realistically drawn objects—ROs). Aims: To compare the identification rate and number of misunderstanding types between SOs and ROs drawn by PWA and healthy controls (HCs). To reveal trends in the misunderstandings of drawings by PWA, and to identify the language or cognitive abilities related to the identification rate of pictures drawn by PWA. Methods & Procedures: We designed a drawing task involving SOs and ROs. A total of 18 PWA and 30 HCs completed the task, and respondents identified the drawings. The identification rate and number of misunderstandings were analysed with two‐way analysis of variance (ANOVA) including group (PWA and HCs) and object type (SOs and ROs). The misunderstandings were divided into four categories varying in semantic and morphological similarity; these ratios were examined with a chi‐square test. The relationships of language and cognitive abilities with the identification rate were investigated with multiple regression analyses. Outcomes & Results: There was a significant effect of the interaction between group and object type on the identification rate (F(1.1387) = 3.90, Mean Squared Error (MSE) = 4139.67, p = 0.04): the identification rates for ROs were lower in the PWA than in the HCs. For the number of misunderstanding types, an interaction was observed between group and object type (F(1.56) = 8.26, MSE = 26.93, p < 0.01): the number of misunderstanding types for ROs in the PWA was greater than that in the HCs. The misunderstanding patterns differed between ROs and SOs (χ2(3) = 694.30, p < 0.001, V = 0.37). ROs were semantically related, whereas SOs were morphologically related. The identification rates of ROs and SOs were correlated only with Kanji writing scores (ROs: β = 3.66, p = 0.01; SOs: β = 6.57, p < 0.01). Conclusions & Implications: In drawings by the PWA, SOs had a higher identification rate, while ROs had a lower identification rate and a greater variety of misunderstandings. SOs may increase drawing motivation. Interventions to improve the identifiability of SOs and ROs should reflect each character. Identification rates were correlated only with Kanji writing scores. The PWA, whose native language was Japanese and had preserved Kanji writing abilities, and their communication abilities may be increased through drawing. WHAT THIS PAPER ADDS: What is already known on the subject: PWA often have impaired drawing abilities and draw pictures that third parties misinterpret. Some objects tend to be drawn symbolically, and some are drawn realistically. However, it is not clear whether there is a difference between these types of drawings depicted by PWA in identifiability and the tendency to be misunderstood by ordinary people. In addition, the relationships between language or cognitive abilities and the identification rate of drawn pictures are not clear. What this paper adds to the existing knowledge: The identification rate differed between SOs and ROs. In drawings by PWA, SOs had a higher identification rate, while ROs had a lower identification rate and the greatest variety of misunderstandings. Approximately half of the misunderstandings were related to the target object. SOs tended to be confused with morphologically related objects, while ROs tended to be confused with semantically related objects. Identification rates were correlated only with Kanji writing scores. What are the potential or actual clinical implications of this work?: To motivate PWA's drawing, it is suitable to begin with SOs. Examining drawing ability from the perspective of SOs and ROs increases the chance of identifying drawing ability. PWA whose native language is Japanese and have preserved Kanji writing abilities may be able to increase their communication abilities through drawing. [ABSTRACT FROM AUTHOR]

This paper highlights the interest of using an Atmospheric Numerical Simulator (ANS) relying on a high resolution weather forecast model coupled with an ElectroMagnetic Module to compute Ka‐band rain attenuation statistics in an equatorial region. An optimization of the parametrization of the Weather Research and Forecasting meteorological model (WRF) is carried out using measurements collected from a propagation experiment carried out by Centre National d'Études Spatiales and Office National d'Études et de Recherches Aérospatiales near Kourou in French Guiana. Both simulated and experimental annual Complementary Cumulative Distribution Functions of rain attenuation are presented and compared. An additional comparison to the rain attenuation prediction method of Rec. ITU‐R P.618‐13 is presented to evaluate the potentialities of the WRF‐EMM ANS to produce synthetic propagation statistics in equatorial regions. Key Points: Simulation of rain attenuation statistics in an equatorial region based on a meteorological modelAn optimization of the meteorological model is presented to obtain a better reproduction of the propagation channelThe long term statistics of rain attenuation compare better than the method of reference to the experimental data [ABSTRACT FROM AUTHOR]

Deteriorated power system components have a higher probability of failure than new components. Still, the reliability of supply analyses traditionally models all components of the same type with the same probability of failure, and thus neglects the effect of deteriorated components. This paper presents a methodology to integrate a condition‐dependent component probability of failure model into a power system reliability analysis. The component state is described by a semi‐Markov process, and the paper shows how this, under reasonable assumptions, can be approximated by a Markov process. The Markov assumption simplifies the analysis and allows the model to include preventive retirement and be calibrated to statistical data. A case study using statistical data for Norwegian power transformers shows that, in the Norwegian power system, the proportion of failures that are due to the poor condition is small, partly due to the common strategy of preventive retirement. However, if the condition of the transformers were worse, the impact of poor conditions can be considerable. The methodology further enables the identification of the transformers that contribute most to the risk to the reliability of supply. The paper thus highlights the importance of accounting for the component condition in strategic decisions such as long‐term renewal planning [ABSTRACT FROM AUTHOR]

Performance assessment is ubiquitous and crucial in people analytics. Scientific impact, particularly, plays a significant role in the academia. This paper attempts to understand researchers' career trajectories by considering the research community as a social network, where individuals build ties with each other via coauthorship. The resulting linkage facilitates information flow and affects researchers' future impact. Consequently, we systematically investigate the career trajectories of researchers with respect to research impact using the social capital theory as our theoretical foundation. Specifically, for early‐stage and mid‐career academics, we find that connections with prominent researchers associate with greater impact. Brokerage positions, in addition, are beneficial to a researcher's research impact in the long run. For senior researchers, however, the only social network feature that significantly affects their future impact is the reputation of their recently built ties. Finally, we build predictive models on future research impact which can be leveraged by both organizations and individuals. This paper provides empirical evidence for how social networks provide signals on researchers' career dynamics guided by social capital theory. Our findings have implications for individual researchers to strategically plan and promote their careers and for research institutions to better evaluate current as well as prospective employees.

Purpose Although tablet computers offer advantages in data collection over traditional paper-and-pencil methods, little research has examined whether the 2 formats yield similar responses, especially with underserved populations. We compared the 2 survey formats and tested whether participants' responses to common health questionnaires or perceptions of usability differed by survey format. We also tested whether we could replicate established paper-and-pencil findings via tablet computer. Methods We recruited a sample of low-income community members living in the rural southern United States. Participants were 170 residents (black = 49%; white = 36%; other races and missing data = 15%) drawn from 2 counties meeting Florida's state statutory definition of rural with 100 persons or fewer per square mile. We randomly assigned participants to complete scales (Center for Epidemiologic Studies Depression Inventory and Regulatory Focus Questionnaire) along with survey format usability ratings via paper-and-pencil or tablet computer. All participants rated a series of previously validated posters using a tablet computer. Finally, participants completed comparisons of the survey formats and reported survey format preferences. Findings Participants preferred using the tablet computer and showed no significant differences between formats in mean responses, scale reliabilities, or in participants' usability ratings. Conclusions Overall, participants reported similar scales responses and usability ratings between formats. However, participants reported both preferring and enjoying responding via tablet computer more. Collectively, these findings are among the first data to show that tablet computers represent a suitable substitute among an underrepresented rural sample for paper-and-pencil methodology in survey research.

Summary: Autonomy is becoming a prime requirement for satellite mission control operations. Data‐driven methods like Machine Learning models are playing a key role in bringing in autonomy. Health keeping data from satellite telemetry is a key ingredient in these data‐driven methods. In real‐world satellite operations, the health‐keeping telemetry data gradually drifts due to adverse space weather effects and wear and tear of electronic and mechanical components. The key question that arises is how to detect and quantify the data drift which is generally a gradual phenomenon. This paper discusses a novel statistical method for detecting data drift occurring in satellite telemetry. For the purpose of experimental work in this paper, an actual telemetry data set of the BUS CURRENT sensor which is part of the Electrical Power System of a Low Earth Orbit Satellite was considered. Data drift detection test was carried out using this sensor data using the developed novel statistical method and with Kolmogorov Smirnov test which is a probabilistic method. Both results are analysed and compared. Thereafter novel statical method was used to check its efficacy using a synthetic data set with induced drift. [ABSTRACT FROM AUTHOR]

Background: A practical test that measures the information and communication technology (ICT) skills students need for effectively using ICT in primary education has yet to be developed (Oh et al., 2021). This paper reports on the development, validation, and reliability of a test measuring primary school students' ICT skills required for effectively using ICT (the ECC‐ICT test). Objectives: Based on existing literature, three ICT use domains were identified for effectively using ICT: Effective, collaborative, and creativeuse of ICT. For these three domains, 24 corresponding teaching objectives were identified from a widely used digital literacy framework. Thirty‐four test items cover these teaching objectives in an online test. Methods: A mixed‐method approach was used for the ECC‐ICT test. Four pilot rounds (n=25) implemented qualitative interviews for cognitive validity and refining the test items, followed by a qualitative usability study(n=6). Confirmatory factor analysis and ANOVA provided quantitative insight into the large‐scale test administration(n=575). Results and Conclusions: Composite reliability of our conceptual 3‐factor confirmatory model showed that the test reliably measured primary school effective use of ICT (ω = 0.82), collaborative use of ICT (ω = 0.80) and creative use of ICT (ω = 0.64). Convergent validity (ranging from 0.41 to 0.46) was acceptable. Internal consistency (ranging from 0.84 to 0.91) and discriminant validity (HTMT values below 0.90) are good. ANOVA results show that mean test scores are higher for students in higher grade levels (p < 0.001). The post hoc Bonferroni results show that most grade‐by‐grade comparisons are significant (p < 0.001). Lay Description: What is already known about this topic: Information and communication technology (ICT) skills are finding their way into national curriculums as teachers implement more digital learning environments.Teachers currently do not have a measurement instrument for the ICT skills primary education students need to learn in a personalised way. What this paper adds: This paper gives teachers a test that reliably measures the effective, collaborative, and creative ICT skills required for primary school students to learn using ICT.To our knowledge, this test is the first of its kind.Al materials to reproduce the test are available digitally for teachers. The implications of study findings for practitioners: For policy, this test can be used to check if a student is ready to use ICT in a self‐regulated setting.With this test, teachers can assess and support students' growth on the effective, collaborative, and creative ICT skills required for primary school students using ICT.

Background: Virtual reality (VR) offers much potential for learning, but it challenges learners' orientation. Objectives: This paper investigates whether it is possible to use light or movement cues to facilitate orientation in a search task in a desktop‐VR environment so that participants can better attend to the learning content presented simultaneously. Methods: In two pre‐registered online experiments, we investigated the effects of cueing (light and movement) on search time, learning, and several evaluation variables. Participants were asked to find tools in a virtual workshop, while information about the respective tool was narrated. Experiment 1 (N = 60) used a within‐subject design, that is, the objects were alternately highlighted by light, movement or not. For Experiment 2 (N = 159) the narration was substantially shortened, and a between‐subject design was used. Cognitive load and presence were measured additionally. Results and conclusions: In Experiment 1, only the movement cue decreased search time, indicating automatic guidance of learners' attention. There was no effect of cueing on learning, which may be due to the average search time being substantially shorter than the narration, leaving sufficient time to attend to the narration exclusively. In Experiment 2 search times were significantly faster for both cueing methods, but only the light cue resulted in better learning outcomes, which could be explained by the slightly lower presence in the movement cue condition. Implications: Results imply that it is important to develop cues that automatically guide attention without reducing presence. Lay Description: What is already known about this topic: Virtual reality (VR) offers a lot of opportunities for the integration of educational scenarios.VR is challenging for learners with regard to orientation in a 360° environment.Regarding learning outcomes, research on the effects of cues to highlight important content in a 360° environment is still rare.Presence, defined as the feeling of being there in a VR environment, is an important prerequisite for learning in VR. What this paper adds: The influence of light and movement cues on search times and learning outcomes in a desktop‐VR environment was tested.Movement cues can reliably reduce search times (indicating successful orientation), whereas light cues only reduced search times in predictable scenarios.In a predictable scenario, light cues enhanced learning outcomes compared with movement cues.Movement cues reduced presence, which is one potential reason why movement cues did not improve learning. Implications for practice and/or policy: Using light cues might assist orientation and enhance overall performance in predictable scenarios (i.e., when learners know what kind of cue to expect).In an unpredictable setting with variable cues, light cues did not facilitate orientation, whereas movement cues did.However, movement cues reduced presence, which may have negatively affected learning outcomes. It is important to develop cueing methods that also work in more unpredictable settings, but that do not reduce presence. [ABSTRACT FROM AUTHOR]

Background: Although existing studies have shown that both repetitive transcranial magnetic stimulation (rTMS) and music therapy have advantages in the treatment of non‐fluent aphasia, the efficacy of the combination of these two methods remains to be investigated. Aims: To investigate the clinical efficacy of low‐frequency rTMS combined with music therapy on language function and depression in patients with non‐fluent aphasia after stroke. Methods & Procedures: A single‐blind parallel randomised controlled trial was conducted. Sixty patients (mean duration = 93.78 days) with non‐fluent aphasia after stroke were randomly divided into a traditional therapy group (n = 20), a music therapy group (n = 20) and a combined therapy group (n = 20, 1 Hz). The language function and depression were evaluated before and 3 weeks after treatment with the Chinese version of the Western Aphasia Battery scale, Boston Diagnostic Aphasia Examination scale and Stroke Aphasic Depression Questionnaire Hospital Version scale. Outcomes & Results: The combined therapy group was significantly better in all outcomes than the traditional therapy group and was significantly better in depression than the music therapy group. The music therapy group was significantly better in repetition and depression than the traditional therapy group. Language improvement was positively correlated with depression improvement. For adverse events, only two patients in the combined therapy group showed slight dizziness during rTMS treatment and their symptoms improved after rest. Conclusions & Implications: Our preliminary randomised controlled study indicates that low‐frequency rTMS combined with music therapy is feasible and safe in improving language function and depression in non‐fluent aphasia patients after stroke. WHAT THIS PAPER ADDS: What is already known on this subject: Repetitive transcranial magnetic stimulation (rTMS) and music therapy respectively have advantages in the treatment of non‐fluent aphasia after stroke, but whether the combination of the two methods is more effective is still unknown. What this paper adds to the existing knowledge: This is one of the first randomised control trials to investigate whether the clinical efficacy of low‐frequency rTMS combined music therapy for non‐fluent aphasia is better. The findings show that low‐frequency rTMS combined music therapy is superior to traditional therapy in spontaneous speech, auditory comprehension, repetition, naming, aphasia quotient, functional language level and depression, and superior to music therapy in depression, while music therapy is superior to traditional therapy in repetition and depression. What are the potential or actual clinical implications of this work?: Low‐frequency rTMS combined music therapy may be a better method for treatment of non‐fluent aphasia. [ABSTRACT FROM AUTHOR]

Background: The Pediatric Eating Assessment Tool (PEDI‐EAT‐10) is a reliable and valid tool for rapid identification of dysphagia in patients aged 18 months to 18 years. Aims: To translate and adapt the PEDI‐EAT‐10 into the Italian language and evaluate its validity and reliability. Methods & Procedures: The translation and cross‐cultural adaptation of the tool consisted of five stages: initial translation, synthesis of the translations, back translation, expert committee evaluation and test of the prefinal version. The internal consistency of the translated tool was analysed in a clinical group composed of 200 patients with special healthcare needs aged between 18 months and 18 years. They were consecutively enrolled at the Rare Disease Unit, Paediatrics Department, Fondazione Policlinico Agostino Gemelli‐IRCCS, Rome. For test–retest reliability, 50 caregivers filled in the PEDI‐EAT‐10 questionnaire for a second time after a 2‐week period. Construct validity was established by comparing data obtained from patients with data from healthy participants (n = 200). The study was approved by the local ethics committee. Outcomes & Results: Psychometric data obtained from patients (104 M; mean age = 8.08 ± 4.85 years; median age = 7 years) showed satisfactory internal consistency (Cronbach's α = 0.89) and test–retest reliability (Pearson r = 0.99; Spearman r = 0.96). A total of 30% of children were classified as having a high risk of penetration/aspiration. The Italian PEDI‐EAT‐10 mean total score of the clinical group was significantly different from that resulting from healthy participants. Conclusions & Implications: The PEDI‐EAT‐10 was successfully translated into Italian, validated and found to be a reliable one‐page rapid screening tool to identify dysphagia in children and adolescents with special needs. What this paper adds: What is already known on the subject: The PEDI‐EAT‐10 is a valid and reliable quick discriminative paediatric tool for identifying penetration/aspiration risks. What this paper adds to the existing knowledge: In the present study we successfully translated and adapted the PEDI‐EAT‐10 into the Italian language. What are the potential or actual clinical implications of this work?: This translation and adaptation increase access to valid feeding and swallowing assessment for children of Italian‐speaking families. In addition, the I‐PEDI‐EAT‐10 can suggest further assessment of patients' swallowing abilities. [ABSTRACT FROM AUTHOR]
