Introduction: Self-managing organizations are a novel organizational form that radically decentralizes decision authority to adapt to the volatile business environment and the demands of knowledge work, resulting in new resources and demands for the employees. Therefore, building on the job demands-resources theory and the person-environment fit theory, the associations of self-managing organizations with higher perceived individual autonomy were tested. Additionally, the study investigated how job crafting and handling mistakes related to the relationship between job autonomy and work engagement/satisfaction. Method: A cross-sectional study was conducted to gather data from employees of different self-managing organizations and non-self-managing organizations, and group comparisons and path analyses were applied to test the preregistered hypotheses. Results: Increased method and decision autonomy, job crafting behaviors, error management orientation, work engagement, and job satisfaction were found in self-managing organizations. Additionally, a surplus of perceived autonomy compared to the ideal autonomy was associated with lower work engagement and job satisfaction compared to a fit between ideal and perceived autonomy. However, job crafting did not relate to a better fit between ideal and perceived autonomy. Decision autonomy predicted higher crafting of challenging demands and structural resources for employees with low error strain. Depending on the autonomy type, learning from errors enhanced or reduced the relationship between perceived autonomy and job crafting. Discussion: This study showed the importance of addressing the higher level of individual autonomy in self-managing organizations and offered starting points for interventions to support employees with handling high autonomy. Reducing error strain but increasing error learning and risking errors could help increase job crafting and work engagement, particularly in self-managing organizations. [ABSTRACT FROM AUTHOR]

The Heart and Flower task is used worldwide to measure age-dependent and individual differences in executive functions and/or cognitive control. The task reliably maps age and individual differences and these have consistently been found to be predictive for different aspects of school readiness and academic achievement. The idea has been put forward that there is a developmental shift in how children approach such a task. While 6-year-olds' tend to adapt their task strategy ad hoc and reactively, older children increasingly engage in proactive cognitive control. Proactive cognitive control entails finding the right response speed without risking errors, always dependent on the cognitive conflict. The main goal of the present contribution was to examine children's adjustments of response speed as a function of age and cognitive conflict by addressing RTs surrounding errors (i.e., errors and post-error trials). Data from a large sample with three age groups was used (N = 106 6-year-olds' with a mean age of 6 years; 3 months; N = 108 7-year-olds' with a mean age of 7 years; 4 months; N = 78 8-year-olds' with a mean age of 8 years; 1 month). Response speed adjustments and the development thereof were targeted both across the Flower and Mixed block, respectively, and within these blocks focusing on errors and post-error slowing. Results revealed evidence for a developmental shift toward more efficient proactive cognitive control between 6 and 8 years of age, with the older but not the younger children strategically slowing down in the Mixed block and smoother post-error slowing. At the same time, we found that even the youngest age group has emerging proactive cognitive control skills at their disposal when addressing post-error slowing in the Flower block. The present study thus tracks the early roots of later efficient executive functions and cognitive control, contributes to a better understanding of how developmental progression in cognitive control is achieved, and highlights new avenues for research in this domain.

The most popular instrument used to measure emotional regulation is the Emotion Regulation Questionnaire (ERQ), allowing researchers to study intergroup differences in emotional regulation across many different cultures. However, to make multi-group comparisons, factors within the measurement instrument must be invariant across groups. This invariance is necessary to ensure that any significant differences found between groups are due to group affiliation and not due to measurement errors in the instrument's factors. The study examined measurement invariance of the ERQ by gender using an Ecuadorian sample, where very few studies have previously investigated this issue. The sample included 815 college students. A confirmatory factor analysis indicated that the bi-factor model presented the best fit. The ERQ was invariant by gender at the strict level according to multi-group confirmatory factor analysis. The ERQ also presented good reliability scores for both men and women with no significant differences between genders. These results confirm that the ERQ is a reliable instrument and that it can detect differences in the use of emotional regulation strategies between men and women without risking errors caused by measurement variance.

Special education is losing its identity—its visibility, distinctiveness, budget, and basic functions are all at risk. Special education functions include (a) sorting, categorizing, and labeling students who need it; (b) making the right comparisons; (c) honoring diversity but changingparticulardifferences; (d) managing stigma; (e) making subjective judgments and risking errors; (f) dealing with students’ failures; and (g) adequate financing in addition to maintaining visibility and status and having its own budget and personnel. It cannot exist without these functions, all of which are criticized or on the decline. Special education must also be reconstructed on the basis of sound science, not alternative narratives or nonscientific ways of knowing that do not help students with disabilities learn all they can. The need for a scientific reconstruction and implications for special education’s future are discussed. [ABSTRACT FROM AUTHOR]

Shaking tables are widely used across numerous engineering research and industrial sectors, including mechanical (e.g. automotive and aerospace testing), electrical (e.g. instrumentation testing) and civil (e.g. structural and geotechnical testing) engineering. It is commonly required to replicate the shake table motions accurately and precisely. Iterative learning control algorithms can be used to complement traditional proportional–integral–differential feedback control algorithms to optimize drive signals using a test payload prior to the real experiment. Historically, the design of these test payloads has focused on matching the mass of the actual payload and neglected its dynamic response. In this study, experimental results from shake table tests using multiple geotechnical containers with dry and saturated beds that exhibit a range of stiffnesses and material damping when shaken are presented. Errors between the demanded and achieved motions are explored and compared to the changing secant stiffness abstracted from the dynamic shear stress–strain loops of the payload. A clear trend emerges that demonstrates increased errors as the payload stiffness deviates from the constant stiffness test payload originally used with the open loop iterative learning control, and further the errors are not necessarily bounded by test payloads significantly softer or stiffer than the actual specimen. The findings support that in cases where repeatable, accurate and precise shake table motions are required for payloads that exhibit a complex material response that is not readily modelled mathematically, it may be necessary to reproduce the specimen's overall dynamic response during the iterative learning control process.

Impostors, confidence artists, and artful deceivers seem to have achieved a strange kind of popularity and even prestige in our contemporary political landscape, for reasons that remain elusive, especially given how harmful and socially unwanted such behaviors ostensibly are. Herman Melville's 1857 novel, The Confidence-Man: His Masquerade, helps us shift our perspective on this seemingly irrational phenomenon because it points out how being susceptible to dupery is linked to the enjoyment of fiction itself. This insight also highlights the importance of epistemological failure in the recent "return to aesthetics" in literary studies, where the positive dimension of unconsciously "willing one's dupery" directly links aesthetic form to politics. The logic that connects aesthetics to unconscious enjoyment is then elaborated in the work of psychoanalytic thinkers such as Sigmund Freud, Jacques Lacan, Helene Deutsch and others to raise particular questions about how and why the enjoyment of being duped has been associated with feminine sexuality. Reading Melville's novel while considering psychoanalytic concepts such as the "as if" personality, imposture, and interpassivity illuminates how confidence games play upon the ruses of sexuality, which have profound implications for why the public remains in thrall to the workings of known deceivers.

Hyperhomocysteinemia (HHcy) is recognized as an independent risk factor for various significant medical conditions, yet controversy persists around its assessment and management. The diagnosis of disorders afffecting homocysteine (Hcy) metabolism faces delays due to insufficient awareness of its clinical presentation and unique biochemical characteristics. In cases of arterial or venous thrombotic vascular events, particularly with other comorbidities, it is crucial to consider moderate to severe HHcy. A nutritional approach to HHcy management involves implementing dietary strategies and targeted supplementation, emphasizing key nutrients like vitamin B6, B12, and folate that are crucial for Hcy conversion. Adequate intake of these vitamins, along with betaine supplementation, supports Hcy remethylation. Lifestyle modifications, such as smoking cessation and regular physical activity, complement the nutritional approach to enhance Hcy metabolism. For individuals with HHcy, maintaining a plasma Hcy concentration below 50 μmol/L consistently is vital to lowering the risk of vascular events. Collaboration with healthcare professionals and dietitians is essential for developing personalized dietary plans addressing the specific needs and underlying health conditions. This integrated approach aims to optimize metabolic processes and reduce the associated health risks. [ABSTRACT FROM AUTHOR]

Within the domain of architectural urban informatization, the automated precision recognition of two-dimensional paper schematics emerges as a pivotal technical challenge. Recognition methods traditionally employed frequently encounter limitations due to the fluctuating quality of architectural drawings and the bounds of current image processing methodologies, inhibiting the realization of high accuracy. The research delineates an innovative framework that synthesizes refined semantic segmentation algorithms with image processing techniques and precise coordinate identification methods, with the objective of enhancing the accuracy and operational efficiency in the identification of architectural elements. A meticulously curated data set, featuring 13 principal categories of building and structural components, facilitated the comprehensive training and assessment of two disparate deep learning models. The empirical findings reveal that these algorithms attained mean intersection over union (MIoU) values of 96.44% and 98.01% on the evaluation data set, marking a substantial enhancement in performance relative to traditional approaches. In conjunction, the framework's integration of the Hough Transform with SQL Server technology has significantly reduced the coordinate detection error rates for linear and circular elements to below 0.1% and 0.15%, respectively. This investigation not only accomplishes the efficacious transition from analog two-dimensional paper drawings to their digital counterparts, but also assures the precise identification and localization of essential architectural components within the digital image coordinate framework. These developments are of considerable importance in furthering the digital transition within the construction industry and establish a robust foundation for the forthcoming extension of data collections and the refinement of algorithmic efficacy.

Background Healthcare leaders look to high-reliability organisations (HROs) for strategies to improve safety, despite questions about how to translate these strategies into practice. Weick and Sutcliffe describe five principles exhibited by HROs. Interventions aiming to foster these principles are common in healthcare; however, there have been few examinations of the perceptions of those who have planned or experienced these efforts. Objective This single-site qualitative study explores how healthcare professionals understand and enact the HRO principles in response to an HRO-inspired hospital-wide safety programme. Methods We interviewed 71 participants representing hospital executives, programme leadership, and staff and physicians from three clinical services. We observed and collected data from unit and hospital-wide quality and safety meetings and activities. We used thematic analysis to code and analyse the data. Results Participants reported enactment of the HRO principles 'preoccupation with failure', 'reluctance to simplify interpretations' and 'sensitivity to operations', and described the programme as adding legitimacy, training, and support. However, the programme was more often targeted at, and taken up by, nurses compared with other groups. Participants were less able to identify interventions that supported the HRO principles 'commitment to resilience' and 'deference to expertise' and reported limited examples of changes in practices related to these principles. Moreover, we identified inconsistent, and even conflicting, understanding of concepts related to the HRO principles, often related to social and professional norms and practices. Finally, an individualised rather than systemic approach hindered collective actions underlying high reliability. Conclusion Our findings demonstrate that the safety programme supported some HRO principles more than others, and was targeted at, and perceived differently across professional groups leading to inconsistent understanding and enactments of the principles across the organisation. Combining HRO-inspired interventions with more targeted attention to each of the HRO principles could produce greater, more consistent high-reliability practices. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this paper is to integrate research conducted on work values, political values and cultural values to develop a new heuristic model of values that can be applied to workplace outcomes. Design/methodology/approach: This is a conceptual paper that draws upon the work values, political values and cultural values literatures and the "similarity leads to attraction" and "dissimilarity leads to repulsion" hypotheses to advocate an integrative conceptual model spanning these constructs. Findings: Integrating the three types of values with the underlying hypotheses of "similarity leads to attraction" and "dissimilarity leads to repulsion", an internally consistent two-factor model of values is developed. This heuristic model argues that one set of factors causes value congruence and its associated outcomes and a different set of factors causes value incongruence and its associated outcomes. By conceptualizing value congruence and value incongruence as a two-factor theory, the idea is advanced that people do not assess value similarity and value dissimilarity unidimensionally, but these are two separate dimensions supported by different theoretical hypotheses and processes. Originality/value: Previous conceptual work on values has isolated different types of values and considered them separately. A contribution is made by integrating the three main streams of values research. The paper is the first to advocate a two-factor theory to values and the first to incorporate the "similarity leads to attraction" and "dissimilarity leads to repulsion" hypotheses. The model repositions the focus for future research on value congruence and incongruence. [ABSTRACT FROM AUTHOR]

Background: The Self-care of Diabetes Inventory (SCODI) is a theory-based tool that measures self-care, a key strategy in the appropriate treatment of diabetes. However, despite the clinical differences between people with Type 1 Diabetes Mellitus (T1DM) and Type 2 Diabetes Mellitus (T2DM), the psychometric properties of the SCODI were only tested in mixed samples.Purpose: This study aims to test the psychometric performances of the SCODI in two separate groups of adults with T1DM and T2DM.Methods: This is a secondary analysis from two previous multicentre cross-sectional observational studies involving patients with T1DM (n = 181) and T2DM (n = 540). We tested dimensionality with confirmatory factor analysis and reliability with a multidimensional model-based coefficient for every scale of the SCODI: self-care maintenance, self-care monitoring, self-care management, and self-care self-efficacy.Results: We found that the SCODI showed the same dimensionality, with minimal variation in factor loadings for each factor and each scale among T1DM and T2DM groups. High reliability for each scale in both groups was also found (self-care maintenance: T1DM = 0.86, T2DM = 0.83; self-care monitoring: T1DM = 0.84, T2DM = 1.00; self-care management: T1DM = 0.87, T2DM = 0.86; self-care self-efficacy: T1DM = 0.88; T2DM = 0.86).Conclusion: The SCODI can be used for measuring self-care in people with T1DM, T2DM, or mixed groups using identical scoring procedures. Considering the well-known differences between Type 1 and Type 2 diabetes diseases and patients' characteristics, our results support the generalizability of the self-care theory on which the instrument is based.

Projectile technology is commonly viewed as a significant contributor to past human subsistence and, consequently, to our evolution. Due to the allegedly central role of projectile weapons in the food-getting strategies of Upper Palaeolithic people, typo-technological changes in the European lithic record have often been linked to supposed developments in hunting weaponry. Yet, relatively little reliable functional data is currently available that would aid the detailed reconstruction of past weapon designs. In this paper, we take a use-wear approach to the backed tool assemblages from the Recent and Final Gravettian layers (Levels 3 and 2) of Abri Pataud (Dordogne, France). Our use of strict projectile identification criteria relying on combinations of low and high magnification features and our critical view of the overlap between production and use-related fractures permitted us to confidently identify a large number of used armatures in both collections. By isolating lithic projectiles with the strongest evidence of impact and by recording wear attributes on them in detail, we could establish that the hunting equipment used during the Level 3 occupations involved both lithic weapon tips and composite points armed with lithic inserts. By contrast, the Level 2 assemblage reflects a heavy reliance on composite points in hunting reindeer and other game. Instead of an entirely new weapon design, the Level 2 collection therefore marks a shift in weapon preferences. Using recent faunal data, we discuss the significance of the observed diachronic change from the point of view of prey choice, seasonality, and social organisation of hunting activities. Our analysis shows that to understand their behavioural significance, typo-technological changes in the lithic record must be viewed in the light of functional data and detailed contextual information.

The article discusses the use of remote consultation in modern general practice. It highlights the heterogeneity in the delivery of general practice services across the UK due to the proliferation of consultation modalities and technologies. Remote consultations can be beneficial for clinically simple or acute problems, leading to speedy resolutions and efficient use of healthcare resources. However, there are risks involved, including errors and harm to patients, which can be mitigated through staff initiative and appropriate training. The article emphasizes the importance of understanding the specific needs and preferences of the local population and the skills required for remote care. It also addresses the training needs of different team members and the challenges faced by patients in navigating digital systems. The procurement process and relationships with suppliers can impact the adoption of new technologies, and equitable access to care should be designed into healthcare systems. The article acknowledges the isolating effects of digital technologies on both patients and the workforce, and the need to balance the benefits of remote care with in-person care. It emphasizes the importance of providing holistic care and the role of perceptual capacity in remote consultations. The article concludes by calling for policymakers to consider guidance that benefits both staff and patients and to avoid using the wrong modality, which can lead to safety incidents and poor patient experience.

A simulation model for nitrogen-fixing cyanobacteria was formulated to predict population and nutrient dynamics in water quality studies. The model tracks population biomasses of nitrogen and phosphorus, which potentially limit population growth. Lack of intracellular nitrogen cues the differentiation of specialised heterocysts for nitrogen fixation. Ecoevolutionary analysis presented here predicts that natural selection optimises heterocyst differentiation in relation to external supplies of nitrogen and phosphorus. Modelling the production of N-rich toxins (e.g. anatoxins, saxitoxins) suggests that both total biomass and the biomass N : P ratio can predict concentrations of toxins. The results suggest hypotheses that major taxa of nitrogen-fixing, nuisance cyanobacteria are differentially adapted to varying nitrogen and phosphorus supplies, and that biomass stoichiometry is related to toxins production in this major group of harmful algae. This approach can be extended into models of community and ecosystem dynamics to explore implications of nitrogen fixation for cyanobacterial biomass and toxins production. Cyanobacteria can cause water quality problems through excessive biomass and the production of toxins. Their ability to become abundant is aided by specialised cells (heterocysts) that obtain nitrogen from the atmosphere. A simulation model describes the dynamics of these specialised cells, of biomass and of the nutrients nitrogen and phosphorus. This model can be used to aid predictions of cyanobacterial biomass and toxins. [ABSTRACT FROM AUTHOR]

Assessing prisoners' risk of recidivism and making risk-management recommendations is central to the work of prison-based psychologists. Risk assessment is particularly crucial when it involves indeterminate sentenced prisoners: psychologists' recommendations have potentially significant consequences both for prisoners and the public. However, little is known about psychologists' experiences of conducting such high stakes risk assessments. This paper reports the results of an exploration of psychologists' experiences, via interviews and discussions with qualified, prison-based psychologists. Analysis using Grounded Theory methods identified one super-ordinate category of meaning, namely The Challenging Context of Risk Assessment, which comprised two sub-categories: (1) pressure of limited resources and (2) pressure of the environment. An additional major category, Risk Assessment as a Weighty Task, comprised three sub-categories: psychologists described (1) a weight of responsibility relating to the magnitude and range of their responsibilities; (2) a weight of expectation from colleagues to provide solutions, and (3) the trainee dilemma associated with the need to balance development of trainee psychologists' competence in risk assessment with being held accountable for their work. Understanding qualified psychologists' experiences of undertaking risk assessments with indeterminate sentenced prisoners can facilitate improvements and build on areas of existing good practice.

Objectives: This paper discusses the phenomenon of re-disorganisation as it applies to publicly-funded mental health services. The term refers to the constant reorganisation of services in the absence of evidence and of unclear benefit. We illustrate the problems of re-disorganisation with some hypothetical examples, as well as discussing the context of these problems.Conclusions: The re-disorganisation of public mental health services may be considered a politically expedient administrative response resulting in the illusion of activity and progress. It may be intentional or unintentional. Re-disorganisation can detract from effective policy, planning and implementation of improvements in provision of public mental health services.

Background: The Global Code of Practice on the International Recruitment of Health Personnel focuses particularly on migration of doctors from low- and middle-income countries. Less is understood about migration from high-income countries. Recession has impacted several European countries in recent years, and in some cases emigration has reached unprecedented levels. This study measures and explores the predictors of trainee doctor emigration from Ireland.Methods: Using a partially mixed sequential dominant (quantitative) study design, a nationally representative sample of 893 trainee doctors was invited to complete an online survey. Of the 523 who responded (58.6% response rate), 423 were still in Ireland and responded to questions on factors influencing intention to practice medicine abroad and are the subjects of this study. Explanatory factors for intention to practice medicine in Ireland in the foreseeable future, the primary outcome, included demographic variables and experiences of working within the Irish health system. Associations were examined using univariable and multivariable logistic regression to estimate odds ratios for factors influencing the primary outcome. Qualitative interviews were conducted with 50 trainee doctors and analysed thematically, exploring issues associated with intention to practice medicine abroad.Results: There were high levels of dissatisfaction among trainee doctors around working conditions, training and career progression opportunities in Ireland. However, most factors did not discriminate between intention to leave or stay. Factors that did predict intention to leave included dissatisfaction with one's work-life balance (odds ratio (OR) 2.51; 95% confidence interval (CI) 1.53-4.10; P < 0.001); feeling that the quality of training in Ireland was poor (OR 1.82; 95% CI 1.09-3.05; P = 0.002) and leaving for family or personal reasons (OR 1.85; 95% CI 1.08-3.17; P = 0.027). Qualitative findings illustrated the stress of doing postgraduate training with inadequate supervision, lack of ring-fenced training time and pressures on personal and family life.Conclusions: Large-scale dissatisfaction with working, training and career opportunities point to systemic factors that need to be addressed by health workforce planners if Ireland is to retain and benefit from a motivated medical workforce, given trainees' perceptions that there are better opportunities abroad.

In social situations, skillful regulation of emotion and behavior depends on efficiently discerning others' emotions. Identifying factors that promote timely and accurate discernment of facial expressions can therefore advance understanding of social emotion regulation and behavior. The present research examined whether trait mindfulness predicts neural and behavioral markers of early top-down attention to, and efficient discrimination of, socioemotional stimuli. Attention-based event-related potentials (ERPs) and behavioral responses were recorded while participants (N = 62; White; 67% female; Mage = 19.09 years, SD = 2.14 years) completed an emotional go/no-go task involving happy, neutral, and fearful facial expressions. Mindfulness predicted larger (more negative) N100 and N200 ERP amplitudes to both go and no-go stimuli. Mindfulness also predicted faster response time that was not attributable to a speed-accuracy trade-off. Significant relations held after accounting for attentional control or social anxiety. This study adds neurophysiological support for foundational accounts that mindfulness entails moment-to-moment attention with lower tendencies toward habitual patterns of responding. Mindfulness may enhance the quality of social behavior in socioemotional contexts by promoting efficient top-down attention to and discrimination of others' emotions, alongside greater monitoring and inhibition of automatic response tendencies.

Anthropogenic edge effects, whereby disturbance strength increases in proximity to ecotone boundaries, are known to strongly affect individual species but we lack a general understanding of how they vary by species, disturbance type and regional context. We deployed 46 camera-trap stations for a total of 3545 trap-days at two sites in Sulawesi, Indonesia, obtaining 937 detections of five vertebrate species. Anoa (Bubalus spp.) were more abundant near edges, booted macaque (Macaca ochreata) and red jungle fowl (Gallus gallus) were less abundant near edges, and edges did not impact Sulawesi warty pig (Sus celebensis) or Malay civet (Viverra tangalunga). But the relative importance of habitat disturbance from agriculture, roads and villages differed for each species, and edge-induced disturbances varied not only in magnitude but also in direction between the study areas. In the strongest instance, macaque local abundance was 3.5 times higher near villages than it was 3 km into the forest in one reserve, but 2.8 times higher 3 km into the forest than near villages in the other reserve. Our results suggest that responses to habitat edges among species and edge types are idiosyncratic, and that landscape-level context can strongly alter the influence of local disturbance on biodiversity.

The ORCID researcher identifier ensures that research outputs can always reliably be traced back to their authors. ORCID also makes it possible to automate the sharing of research information, thereby increasing data quality, reducing duplication of effort for academics and saving institutions money. In 2014, Imperial College London created ORCID identifiers (iDs) for academic and research staff. This article discusses the implementation project in the context of the role of ORCID in the global scholarly communications system. It shows how ORCID can be used to automate reporting, help with research data publication and support open access (OA). [ABSTRACT FROM AUTHOR]

Haavelmo was the first to recognize the capacity of economic models to guide policies. This paper describes some of the barriers that Haavelmo’s ideas have had (and still have) to overcome and lays out a logical framework that has evolved from Haavelmo’s insight and matured into a coherent and comprehensive account of the relationships between theory, data, and policy questions. The mathematical tools that emerge from this framework now enable investigators to answer complex policy and counterfactual questions using simple routines, some by mere inspection of the model’s structure. Several such problems are illustrated by examples, including misspecification tests, nonparametric identification, mediation analysis, and introspection. Finally, we observe that economists are largely unaware of the benefits that Haavelmo’s ideas bestow upon them and, to close this gap, we identify concrete recent advances in causal analysis that economists can utilize in research and education.

Since their inception in the early- to mid-2000s, social media sites (SMS) have burgeoned into a popular leisure pursuit with millions of users worldwide. Defined as Internet-based software programs that facilitate communication among individuals, members use them to exchange information, develop friendships, and find social support. Despite their rapid growth as a leisure time activity, there is a dearth of research exploring use of SMS. Using social identity theory as a framework, this study uses quantitative and qualitative data to explore how people who identified as “Penn Staters” used SMS to connect with others and exchange information during and in the wake of the breaking news of the Sandusky Scandal (SS). As predicted, highly identified Penn Staters used SMS to cope with news of the SS. However, interesting variations in usage based on demographic information are presented and discussed, providing greater insight into this increasingly popular leisure trend. [ABSTRACT FROM AUTHOR]

Background: For optimal treatment of patients with non-small cell lung carcinoma, it is essential to have physicians with competence in endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). EBUS training and certification requirements are under discussion and the establishment of basic competence should be based on an objective assessment of performance. Objectives: The aims of this study were to design an evidence-based and credible EBUS certification based on a virtual-reality (VR) EBUS simulator test. Methods: Twenty-two respiratory physicians were divided into 3 groups: experienced EBUS operators (group 1, n = 6), untrained novices (group 2, n = 8) and simulator-trained novices (group 3, n = 8). Each physician performed two standardized simulated EBUS-TBNA procedures. Simulator metrics with discriminatory ability were identified and reliability was explored. Finally, the contrasting-groups method was used to establish a pass/fail standard, and the consequences of this standard were explored. Results: Successfully sampled lymph nodes and procedure time were the only simulator metrics that showed statistically significant differences of p = 0.047 and p = 0.002, respectively. The resulting quality score (QS, i.e. sampled lymph nodes per minute) showed an acceptable reliability and a generalizability coefficient of 0.67. Reliability of 0.8 could be obtained by testing in 4 procedures. Median QS was 0.24 (range 0.21-0.26) and 0.098 (range 0.04-0.21) for groups 1 and 2, respectively (p = 0.001). The resulting pass/fail standard was 0.19. Group 3 had a median posttraining QS of 0.11 (range 0-0.17). None of them met the pass/fail standard. Conclusions: With careful design of standardized tests, a credible standard setting and appropriate transfer studies, VR simulators could be an important first line in credentialing before proceeding to supervised performance on patients.

Fifty-eight porcelain samples in Guan ware style from the collections of the Palace Museum in Beijing were analysed using non-destructive ED-XRF. These included 40 vessels that were traditionally ascribed as Guan wares of the Song Dynasty, and 18 vessels traditionally ascribed as imitation Guan wares, made during the Ming and Qing Dynasties. The purposes of this study were: (1) to cross-check the traditional identification of these wares with the new classification based on their chemical compositions; and (2) to carry out a provenance study of the authentic Song Guan wares-that is, to compare the chemical compositions of the authentic Song Guan wares with those of the shards unearthed from the known Guan ware kilns of the Song Dynasty. This study shows that: (1) the chemical compositions of the glaze are significantly different between the Song Guan wares and the imitation wares-among the 58 wares tested, seven are likely to have been misidentified by the traditional method; and (2) the glaze compositions of the authentic Song Guan wares themselves are not homogeneous, and they can be divided into three groups. The provenance of these groups was briefly investigated. [ABSTRACT FROM AUTHOR]

This study examines the dynamics of cognitive processes during writing. Participants were 5th, 7th and 9th graders ranging in age from 10 to 15 years. They were shown a short silent video composed of clips illustrating conflictual situations between people in school, and were invited to produce a narrative text. Three chronometric measures of word n were analyzed using a Linear Mixed-Effects Model regression procedure: pause duration before word n, pause duration within word n, and writing rate of word n. The predictors were sublexical and lexical properties of word n, i.e., immediacy effects, word n − 1, i.e., delayed effects, and of word n + 1, i.e., anticipatory effects . The writing-rate and the intra-word-pause measures show both immediacy and anticipatory effects. However, the between-word-pause durations show only delayed effects, which has not been reported in previous studies. As far as we know, our study is the first investigation which reveals the occurrence of parallel and serial effects in written text production: preprocessing of word n + 1 occurs when word n is being written, and properties of word n − 1 still exert their influences while the pen has already moved to the next word.

Traditional models hold that the plastic reorganization of brain structures occurs mainly during childhood and adolescence, leaving adults with limited means to learn new knowledge and skills. Research within the last decade has begun to overturn this belief, documenting changes in the brain's gray and white matter as healthy adults learn simple motor and cognitive skills [Lövdén, M., Bodammer, N. C., Kühn, S., Kaufmann, J., Schütze, H., Tempelmann, C., et al. Experience-dependent plasticity of white-matter microstructure extends into old age.

Although the significance of these changes is not fully understood, they reveal a brain that remains plastic well beyond early developmental periods. Here we investigate the role of adult structural plasticity in the complex, long-term learning process of foreign language acquisition. We collected monthly diffusion tensor imaging scans of 11 English speakers who took a 9-month intensive course in written and spoken Modern Standard Chinese as well as from 16 control participants who did not study a language. We show that white matter reorganizes progressively across multiple sites as adults study a new language. Language learners exhibited progressive changes in white matter tracts associated with traditional left hemisphere language areas and their right hemisphere analogs. Surprisingly, the most significant changes occurred in frontal lobe tracts crossing the genu of the corpus callosum--a region not generally included in current neural models of language processing. These results indicate that plasticity of white matter plays an important role in adult language learning and additionally demonstrate the potential of longitudinal diffusion tensor imaging as a new tool to yield insights into cognitive processes.

Older adults adopt memory-based response strategies during consistent practice more slowly and less completely than younger adults. In two experiments, participants either prelearned all, half, or none of the noun-pair stimuli prior to the completion of a standard noun-pair lookup task. Higher proportions of prelearning generally led to a faster and more complete strategic shift from visual scanning to memory retrieval during the lookup task, and a strong prelearning criterion for all items eliminated the age-related slowing of retrieval shift. However, the 50% prelearned condition resulted in strategy shift that was inconsistent with simple mechanistic associative learning, revealing a strategic set that was retrieval-avoidant in older adults.

Objective: A qualitative study performed with a cross-sectional survey to report staff perceptions on emergency department (ED) communication while trialling a personal hands-free wireless communication device (WCD) between August and October 2008 in a busy inner city ED. Method: A survey of all Royal London Hospital ED staff was conducted pre and post-implementation of a personal WCD. The survey included responses to occupation, experience, communication modes, communication wait times, perceived interruptions at the bedside and general perceptions of communication efficiency. Results: No appreciable change in communication modes or perceived waiting times was reported No increase in bedside interruptions were reported. An overwhelming number of respondents considered the system had contributed significantly to improving the quality of the work environment, patient safety and care. Conclusion: This study correlated with others showing a very strong perception of improved communication and working environment: less noise, better handovers and improved staff resource use. The study adds to the limited number of published trials examining WCD in health care. Observational reports post-implementation were overwhelmingly positive. Quantitative studies measuring the impact on patient flow, safety and cost benefits should be considered. [ABSTRACT FROM AUTHOR]

An essay is presented on the ways in which heuristics and biases can influence the decisions of patients. It features clinical examples to show the effects of heuristics and biases and argues for the need of their understanding by physicians to rebias patients and promote their health and other values. It also describes techniques used by physicians in order to present health decisions which are likely to motivate patients towards less biased and more long term conducive decisions.

The article presents information on the role of antitrust laws in controlling excessive pricing with reference to the court case in South Africa related to pricing practices of Mittal Steel South Africa Ltd. Execessive prices are defined as the price well above the level under viable competition. It is also said that excessive prices are not always self-correcting.

To evaluate the prescription writing skill of final year residents in a family practice residency programme (FPRP) in Bahrain, and to compare skill of residents who have graduated from medical schools with problem based learning (PBL) versus traditional (non-PBL) curricula. Prescriptions issued by the residents were prospectively collected for two consecutive cohorts in May 2004 and May 2005. Prescription errors were classified as errors of omission (minor and major), commission (incorrect information) and integration (drug-drug interactions). In 69.6% of medications with major omission errors, dosage form (39.4%) and length of treatment (18.5%) were not specified. In 24.7% of medications with commission errors, dosing frequency (19.9%) and incorrect strength/dose (2.2%) were the most common errors. Integration errors comprised 5.7% of all prescribing errors. No significant differences were observed between PBL and non-PBL graduates with regard to the total number of prescriptions with errors, drugs per prescription, polypharmacy, and the total number of drugs with errors. The proportion of prescriptions with a potential for drug-drug interactions was comparable between PBL and non-PBL graduates. PBL graduates prescribed medications using brand names at a rate greater than non-PBL, whereas non-PBL graduates prescribed medications on inappropriate "as required" basis, and injections at a rate greater than PBL residents. Prescription writing skill of the final year residents in an FPRP programme was suboptimal for both PBL and non-PBL graduates. Integration of prescription writing skill and a rational pharmacotherapeutic programme into the FPRP curriculum is recommended. [ABSTRACT FROM AUTHOR]

This paper discusses a chip that was designed to show how well different power-saving techniques work. The video, which played on a tiny display mounted on the chip's motherboard, showed faint wisps of smoke coming from the package as the device coughed into life for the first time. The chip came from the fab in full working order but a problem with the packaging meant performing a quick repair, which allowed the chip to boot up. The smoke came from the residue left by the fix rather than overactive transistors. It quickly dissipated. What the video did not show was what was happening on the chip that was playing it back. The processor was producing full-motion video with no jerks, stops or judders. Yet, in between each frame, the processor put itself to sleep in an attempt to save power. It was just one example of the intense focus that system-on-chip (SoC) designers now have to put on power - saving it wherever possible - to stop them leaching away the charge in a battery before the device does anything useful. The chip itself was the latest in a series of designs ARM has put together with tools supplier Synopsys to investigate different aspects of circuit design and system architecture.

This article describes the results of a broad reanalysis of factors shaping the prospects of countries making a transition to or from democracy using a new measure of regime type. While some of the results are consistent with prior quantitative and comparative research, others are not. For example, in line with other studies, the article finds that autocracies are more likely to make a transition to democracy when they offer broader protections for civil liberties, experience a change in political leadership, or suffer an economic downturn. At the same time, the analysis does not support the claim that transitions in neighbouring countries directly improve prospects for a transition to democracy, or that economic decline and presidential systems heighten the risk of democratic breakdown. Perhaps most intriguing, our model of transitions to democracy also identifies a new twist on old stories linking economic development to democratization. For countries under authoritarian rule that have attempted democracy before, the research here indicates that development does improve prospects for another attempt, as modernization theory suggests. For countries with no democratic experience, however, affluence conveys no direct democratizing benefit and appears, if anything, to help sustain authoritarian rule. [ABSTRACT FROM AUTHOR]

Following a summary of the American legal doctrine of informed consent and its ethical underpinnings and a description of the risk management reasons that health care providers should comply with the legal requirements associated with this doctrine, this article presents a preliminary argument for an additional incentive for such compliance. Specifically, this article enunciates the outline of a business case for informed consent in health care in the United States, urging by analogy to the widely advocated business case for quality and safety in health care that more conscientious adherence to the principles of informed consent will serve the self-interests of health care providers trying to maintain financial viability within an increasingly competitive marketplace for patients.
