PROsetta: An R Package for Linking Patient-Reported Outcome Measures

A common problem when using a variety of patient-reported outcomes (PROs) for diverse populations and subgroups is establishing a harmonized scale for the incommensurate outcomes. The lack of comparability in metrics (e.g., raw summed scores vs. scaled scores) among different PROs poses practical challenges in studies comparing effects across studies and samples. Linking has long been used for practical benefit in educational testing. Applying various linking techniques to PRO data has a relatively short history; however, in recent years, there has been a surge of published studies on linking PROs and other health outcomes, owing in part to concerted efforts such as the Patient-Reported Outcomes Measurement Information System (PROMIS^®) project and the PRO Rosetta Stone (PROsetta Stone^®) project (www.prosettastone.org). Many R packages have been developed for linking in educational settings; however, they are not tailored for linking PROs where harmonization of data across clinical studies or settings serves as the main objective. We created the PROsetta package to fill this gap and disseminate a protocol that has been established as a standard practice for linking PROs.     

individual and work‐related factors influencing burnout of mental health professionals: a meta‐analysis

The current study identifies and assesses individual and work‐related factors as correlates of burnout among mental health professionals. Results of a meta‐analysis indicate that age and work setting variables are the most significant indicators of emotional exhaustion and depersonalization. In terms of level of personal accomplishment, the age and work hours variables were the most significant indicators with positive correlations. On the basis of these results, the authors seek to determine resources that can assist with developing programs for preventing and treating burnout syndromes of mental health professionals.     

Is compatibilism intuitive?

Eddy Nahmias, with various collaborators, has used experimental data to argue for the claim that folk intuition is generally compatibilist. We try to undermine this claim in two ways. First, we argue that the various formulations of determinism he uses are not conceptually equivalent, jeopardizing the kinds of conclusions that can be drawn from the resulting data. Second, prompted by these conceptual worries we supplement the typical quantitative surveys that dominate the extant literature with short qualitative interviews. This, in turn, guides us to make a minor modification to the quantitative survey that provides better access to the relevant folk intuitions.     

Unemployed and exhausted? Job-search fatigue and reemployment quality

Job loss and job search are particularly devastating and stressful events that individuals can experience in their careers. However, less research attention has been paid to fatigue or burnout in the context of unemployment and job search. Drawing from Conservation of Resources theory, this study highlights the role that fatigue plays during unemployment and job search among displaced employees — defined as individuals who have lost their jobs involuntarily and are currently not engaged in any form of paid employment. In a two-wave longitudinal study involving 89 displaced employees, we illustrate how financial difficulties and social exclusion can lead to job search fatigue, while psychological capital serves as a personal resource that reduces job seekers' fatigue. We also demonstrate how job search fatigue at Time 1 can lead to lower reemployment quality at Time 2, which, in turn, can lead to lower organizational commitment and increased turnover intentions. Our findings bring into attention the important role that fatigue can play in the context of unemployment and job search.     

The Relevance of Sociocultural Theory to Culturally Diverse Partnerships and Communities

The phenomenal growth of information technology and globalization promises a future where education about diversity and difference will be very significant. In this information age where existing knowledge and technology are constantly being replaced in an ever changing interdependent global environment, the fundamentals of education are also changing. Education will focus on building new knowledge rather than passing on existing knowledge. The increasing interconnectedness between cultures and their concomitant intermixing as a result of globalization requires that pedagogies about cultural diversity also focus on creating new knowledge and meanings about cultures as they change. In this article, we discuss sociocultural theory as an alternative educational pedagogy that situates the teaching and learning of cultural diversity within rapidly changing local and global conditions. We argue that features of this theory are especially relevant to providing a guiding pedagogy for valuing difference in inclusive environments. We engage the literature on cross-cultural communication and collaboration between culturally diverse professionals and parents of children with disabilities to illustrate sociocultural perspectives on conceptualizing cultural differences and their interaction, and the possibilities for creating culturally inclusive partnerships and communities.     

Focal dystonia: current theories.

Dystonia is a syndrome characterised by abnormal involuntary sustained muscle contractions that often result in twisted and abnormal positions. Focal dystonia affects only a single body part with symptoms varying from permanent (e.g., torticollis) to task-specific (e.g., musician's cramp). The exact causes of focal dystonia have yet to be determined. Possible causative factors have been identified at all levels along the sensorimotor pathway, including anatomical constraints of the hand (musicians), abnormal co-contractions of the muscles due to reciprocal inhibition in the spinal cord, subcortical and cortical remapping, deficiencies in sensorimotor integration and perceptual deficits. A review of the current literature on these topics is provided with a special focus on musicians with focal dystonia. Also reviewed are current treatments of focal dystonia in musicians. On the basis of the currently available evidence, certain risk factors are identified for the development of task-specific focal dystonia, including number of practice hours, personality, genetic predisposition, performance factors and sensory effects. In addition, it is highlighted that dystonic movements occur predominantly in the context of perceptual-motor tasks involving emotions. When emotional and motor traces have become associated, they are difficult to change; it is suggested that this mechanism plays an important role in the preservation of dystonic symptoms.     

Judgemental adjustment of initial forecasts: Its effectiveness and biases

Managers are often required to integrate their own forecasts with statistical forecasts. The studies reported in this paper examine the efficacy of allowing people to adjust their own forecasts in the light of statistical forecasts that are provided to them. Three experimental studies varied the reliability of the statistical forecasts and examined the performance of people over time. Issues of the form of the feedback and the use of decision support were also examined. The results unequivocally suggest that the effectiveness of judgemental adjustment depended on the statistical model's reliability and seasonally of time series. However, people had considerable difficulty placing less weight on their own forecasts (compared to the statistical forecasts) and this behaviour became more pronounced over time. Even provision of decision support did not improve performance at the task.     

Influence of extended practice on programming time, movement time, and transfer in simple target-striking responses

Two experiments describe the effects of extended practice on the development of motor control programs for simple target-striking responses. In Experiment 1,400 right-hand trials of simple one-target and two-target striking tasks were performed. In Experiment 2,600 practice trials were given. Overall reaction time (RT) was faster for the one-target condition in both experiments, supporting a response complexity effect. Movement time (MT) for both conditions improved linearly with practice, suggesting that development of the motor control programs was still occurring. Subjects then transferred to a three-target condition for 50 trials, performing the transfer task with the right hand in Experiment 1, and with right and left hands in Experiment 2. Transfer to the three-target conditions produced execution errors in the form of failure to contact the second target and repetitive tapping on the third target. These results suggest that extensive practice may serve to firmly entrench a response sequence, making it difficult to implement a similar, but unique, motor control program. An interpretation in terms of automaticity and enhanced priming of behavioral and neural pathways is offered to account for these results.
