AbstractThe present study, aligned with the structural approach on social representations (SR), aimed at comparing dichotomous (central vs. peripheral) and continuous models of structural status of SR elements. The sample was formed by 114 undergraduate students who completed context independence tasks and resistance to change evaluations related to 30 elements from 3 SR objects. Non-nested regression models having resistance to change as the criterion variable and dichotomous and continuous operationalizations of symbolic value as predictors were compared. Statistical results complemented by follow-up t-tests challenge the dichotomous model and support a continuous quadratic one. The curve is interpreted as being related to different evaluations when elements are attributed to a majority or a minority and point out to the need to employ within subjects designs in future research assessing more properties with composite measures.

Worry has been experimentally linked to a range of cognitive consequences, including impairments in working memory, inhibition, and cognitive control. However, findings are mixed, and the effects of worry on other phenomenologically-relevant constructs, such as sustained attention, have received less attention. Potential confounds such as speed-accuracy tradeoffs have also received little attention, as have psychometric and related design considerations, and potential moderators beyond trait worry. The present study investigated the effects of experimentally-induced worry versus a neutral control condition on speed-accuracy tradeoff-corrected performance on a validated measure of sustained attention (88 participants; within-subjects). Moderation by trait worry and trait mindfulness was probed in confirmatory and exploratory analyses, respectively. Worry led to faster and less accurate responding relative to the neutral comparison condition. There was no main effect of condition or trait worry on sustained attention after accounting for speed-accuracy tradeoffs. In exploratory analyses, higher trait mindfulness was robustly related to better post-worry performance, including after controlling for trait worry, general distress, and post-neutral performance, and correction for multiple comparisons. Follow-up analyses exploring dissociable mindfulness facets found a robust relationship between present-moment attention and post-worry performance. Future research should experimentally manipulate mindfulness facets to probe causality and inform treatment development.

Shed Light

Research methodology courses are challenging for students and instructors. They demand students and teachers to master abstract knowledge of the content. Therefore, the present study attempted to shed light on active teaching and learning—an instructional approach that engages learners in interactions and reflection on learning—of research methodology from the perspectives of undergraduates and the course instructor at Majmaah university. Classroom observations and follow-up interviews with 14 undergraduate students and the course instructor were conducted to achieve this. While the participants highlighted some benefits (learning about research methods, enhancing their assignments, raising their interests in research methodology, learning through group work, and discussions and feeling satisfied and self-confident), they also faced several challenges (content-related challenges, task-related challenges, and active learning-related challenges). Thus, the study offers useful theoretical and pedagogical implications for instructors and future research on circumventing challenging issues in such courses.

Background: In China, where follow-up with hospitalized attempters is generally lacking, there is a great need for inexpensive and effective means of maintaining contact and decreasing recidivism. Aims: Our objective was to test whether mobile telephone message contacts after discharge would be feasible and acceptable to suicide attempters in China. Methods: Fifteen participants were recruited from suicide attempters seen in the Emergency Department in Wuhan, China, to participate in a pilot study to receive mobile telephone messages after discharge. All participants have access to a mobile telephone, and there is no charge for the user to receive text messages. Results: Most participants (12) considered the text message contacts an acceptable and useful form of help and would like to continue to receive them for a longer period of time. Conclusions: This suggests that, as a low-cost and quick method of intervention in areas where more intensive follow-up is not practical or available, telephone messages contacts are accessible, feasible, and acceptable to suicide attempters. We hope that this will inspire future research on regular and long-term message interventions to prevent recidivism in suicide attempters.

Abstract. Evidence on the existence of the ego depletion phenomena as well as the size of the effects and potential moderators and mediators are ambiguous. Building on a crossover design that enables superior statistical power within a single study, we investigated the robustness of the ego depletion effect between and within subjects and moderating and mediating influences of the ego depletion manipulation checks. Our results, based on a sample of 187 participants, demonstrated that (a) the between- and within-subject ego depletion effects only had negligible effect sizes and that there was (b) large interindividual variability that (c) could not be explained by differences in ego depletion manipulation checks. We discuss the implications of these results and outline a future research agenda.

SummaryA high incidence of post-discharge venous thromboembolism in orthopaedic surgery patients has been recently reported drawing further attention to the unresolved issue of the optimal duration of the pharmacological prophylaxis. We performed an overview analysis in order to evaluate the incidence of late occurring clinically overt venous thromboembolism in major orthopaedic surgery patients discharged from the hospital with a negative venography and without further pharmacological prophylaxis. We selected the studies published from January 1974 to December 1995 on the prophylaxis of venous thromboembolism after major orthopaedic surgery fulfilling the following criteria: 1) adoption of pharmacological prophylaxis, 2) performing of a bilateral venography before discharge, 3) interruption of pharmacological prophylaxis at discharge in patients with negative venography, and 4) post-discharge follow-up of the patients for at least four weeks. Out of 31 identified studies, 13 fulfilled the overview criteria. The total number of evaluated patients was 4120. An adequate venography was obtained in 3469 patients (84.1%). In the 2361 patients with negative venography (68.1%), 30 episodes of symptomatic venous thromboembolism after hospital discharge were reported with a resulting cumulative incidence of 1.27% (95% C.I. 0.82-1.72) and a weighted mean incidence of 1.52% (95% C.I. 1.05-1.95). Six cases of pulmonary embolism were reported. Our overview showed a low incidence of clinically overt venous thromboembolism at follow-up in major orthopaedic surgery patients discharged with negative venography. Extending pharmacological prophylaxis in these patients does not appear to be justified. Venous thrombi leading to hospital re-admission are likely to be present but asymptomatic at the time of discharge. Future research should be directed toward improving the accuracy of non invasive diagnostic methods in order to replace venography in the screening of asymptomatic post-operative deep vein thrombosis.

Programming Errors

[This Proceedings paper was revised and published in the 2019 issue of the Journal of Information Technology Education: Innovations in Practice, Volume 18.] Aim/Purpose: The study examined types of errors made by novice programmers in different Java concepts with students of different ability levels in programming as well as the perceived causes of such errors. Background: To improve code writing and debugging skills, efforts have been made to taxonomize programming errors and their causes. However, most of the studies employed omnibus approaches, i.e. without consideration of different programing concepts and ability levels of the trainee programmers. Such concepts and ability specific errors identification and classifications are needed to advance appropriate intervention strategy. Methodology: A sequential exploratory mixed method design was adopted. The sample was an intact class of 124 Computer Science and Engineering undergraduate students grouped into three achievement levels based on first semester performance in a Java programming course. The submitted codes in the course of second semester exercises were analyzed for possible errors, categorized and grouped across achievement level. The resulting data were analyzed using descriptive statistics as well as Pearson product correlation coefficient. Qualitative analyses through interviews and focused group discussion (FGD) were also employed to identify reasons for the committed errors. Contribution:The study provides a useful concept-based and achievement level specific error log for the teaching of Java programming for beginners. Findings: The results identified 598 errors with Missing symbols (33%) and Invalid symbols (12%) constituting the highest and least committed errors respec-tively. Method and Classes concept houses the highest number of errors (36%) followed by Other Object Concepts (34%), Decision Making (29%), and Looping (10%). Similar error types were found across ability levels. A significant relationship was found between missing symbols and each of Invalid symbols and Inappropriate Naming. Errors made in Methods and Classes were also found to significantly predict that of Other Object concepts. Recommendations for Practitioners: To promote better classroom practice in the teaching of Java programming, findings for the study suggests instructions to students should be based on achievement level. In addition to this, learning Java programming should be done with an unintelligent editor. Recommendations for Researchers: Research could examine logic or semantic errors among novice programmers as the errors analyzed in this study focus mainly on syntactic ones. Impact on Society: The digital age is code-driven, thus error analysis in programming instruction will enhance programming ability, which will ultimately transform novice programmers into experts, particularly in developing countries where most of the software in use is imported. Future Research: Researchers could look beyond novice or beginner programmers as codes written by intermediate or even advanced programmers are still not often completely error free.

This is a pdf of the original typed manuscript of a lecture made in 2006. An annotated English translation will be published by the International Review of Social Psychology. I this text, Moscovici seeks to update his earlier work on the “conspiracy mentality” (1987) by considering the relationships between social representations and conspiracy mentality. Innovation in this field, Moscovici argues, will require a much thorough description and understanding of what conspiracy theories are, what rhetoric they use and what functions they fulfill. Specifically, Moscovici considers conspiracies as a form of counterfactual history implying a more desirable world (in which the conspiracy did not take place) and suggests that social representation theory should tackle this phenomenon. He explicitly links conspiracy theories to works of fiction and suggests that common principles might explain their popularity. Historically, he argues, conspiracism was born twice: First, in the middle ages, when their primary function was to exclude and destroy what was considered as heresy; and second, after the French revolution, to delegitimize the Enlightenment, which was attributed to a small coterie of reactionaries rather than to the will of the people. Moscovici then considers four aspects (“thematas”) of conspiracy mentality: 1/ the prohibition of knowledge; 2/ the duality between the majority (the masses, prohibited to know) and “enlightened” minorities; 3/ the search for a common origin, a “ur phenomenon” that connects historical events and provides a continuity to History (he notes that such a tendency is also present in social psychological theorizing); and 4/ the valorization of tradition as a bulwark against modernity. Some of Moscovici’s insights in this talk have since been borne out by contemporary research on the psychology of conspiracy theories, but many others still remain fascinating potential avenues for future research.

The purpose of this study was to explore recreational prescription drug use among undergraduate students. Although anecdotal accounts on this subject abound, empirical research is extremely limited. Data from a survey of a random sample of 734 students at a large public research university in the Northeast were examined. Results indicate that a substantial proportion of students reported having used prescription drugs for recreational purposes in the year prior to survey administration. Recreational prescription drug use was positively associated with the use of other substances including alcohol. Recreational prescription drug users were also more likely than other drug users to report negative consequences as a result of their drug use. Implications for future research and for student affairs are discussed.

Conceptual frameworks for racial/ethnic health disparities are abundant, but many have received insufficient empirical attention. As a result, there are substantial gaps in scientific knowledge and a range of untested hypotheses. Particularly lacking is specificity in behavioral and biological mechanisms for such disparities and their underlying social determinants. Alongside lack of political will and public investment, insufficient clarity in mechanisms has stymied efforts to address racial health disparities. Capitalizing on emergent findings from the Midlife in the United States (MIDUS) study and other longitudinal studies of aging, this chapter evaluates research on health disparities between black and white US adults. Attention is given to candidate behavioral and biological mechanisms as precursors to group differences in morbidity and mortality and to environmental and sociocultural factors that may underlie these mechanisms. Future research topics are discussed, emphasizing those that offer promise with respect to illuminating practical solutions to racial/ethnic health disparities.

The Relationship

The authors examined the acceptability ratings of positive reinforcement procedures recommended to parents seen in a pediatric behavior management outpatient clinic. Parental ratings of acceptability were obtained in the clinic and 1, 3, and 6 months following their initial clinic visit. Acceptability variables were examined by group (parents who rated the acceptability of treatments as high vs. low) and by severity (parents who rated their children's behavior problem as severe vs. mild). The relationship between these variables and reported compliance was also examined. Results show that the acceptability variables were useful in differentiating between parents who rated treatments to be more acceptable and parents who rated treatments to be less acceptable. Differences were also observed as a function of behavior problem severity. Significant correlations occurred between acceptability variables and compliance at each of the follow-up points. Results are discussed in relation to the clinical significance of these findings and the impetus they might serve for future research.
