Mediation Analysis in Social Psychology: Current Practices and New Recommendations

A key aim of social psychology is to understand the psychological processes through which independent variables affect dependent variables in the social domain. This objective has given rise to statistical methods for mediation analysis. In mediation analysis, the significance of the relationship between the independent and dependent variables has been integral in theory testing, being used as a basis to determine (1) whether to proceed with analyses of mediation and (2) whether one or several proposed mediator(s) fully or partially accounts for an effect. Synthesizing past research and offering new arguments, we suggest that the collective evidence raises considerable concern that the focus on the significance between the independent and dependent variables, both before and after mediation tests, is unjustified and can impair theory development and testing. To expand theory involving social psychological processes, we argue that attention in mediation analysis should be shifted towards assessing the magnitude and significance of indirect effects.     

Openness in the Social Sciences: Sharing Data

The sharing of research data is now mandated by some funders to encourage openness and integrity in science, to ensure efficient use of research funds, and to provide training resources. Although data sharing has a long history in some parts of science, the full range of possibilities and challenges it offers are only now becoming apparent in the social sciences. This article (a) examines what may be entailed in sharing documented data, (b) provides a historical perspective on data sharing, (c) describes some of the creative and successful data-sharing relationships that have occurred in the social sciences, and (d) discusses some of the main concerns of social scientists with respect to sharing their data and how these concerns might be resolved.

Assessment Centers: Current Practices in the United States

Purpose  

The goals of this investigation were to review current AC practices in the United States by evaluating whether they follow the Guidelines and Ethical Considerations for Assessment Center Operations (International Task Force on Assessment Centers, 2000). We both expanded upon and compared our results to a prior benchmarking study (Spychalski et al. in Personnel Psychol, 50:71–90, 1997), and investigated practices regarding job analysis, AC development, dimensions (i.e., job requirements), exercises, assessor characteristics and training, behavior recording, data integration, organizational policy, assessee rights, AC evaluation and AC technology. Data were collected via an online survey completed by individuals from human resource departments of organizations (N = 54) across the U.S; organizations to whom the survey was sent were selected by sampling Fortune 500 organizations based on economic sector.     

Historical and Philosophical Perspectives on Experimental Practice in Medicine and the Life Sciences

The aim of this paper is to discuss a key question in the history and philosophy of medicine, namely how scholars should treat the practices and experimental hypotheses of modern life science laboratories. The paper seeks to introduce some prominent historiographical methods and theoretical approaches associated with biomedical research. Although medical scientists need no convincing that experimentation has a significant function in their laboratory work, historians, philosophers, and sociologists long neglected its importance when examining changes in medical theories or progress in scientific knowledge. The reason appears to have been the academic influence of the then dominant tradition in the history of ideas, but was also due to a misconception of what could usefully be termed the view on “historical ontology.” During the last two decades, there have been many books and research articles that have turned towards the subject, so that the study of experimental practice has become a major trend in the contemporary history and philosophy of medicine. A closer look at the issue of laboratory research shows that concepts in medicine and the life sciences cannot be understood as historically constant, free-standing ideas, but have to be regarded as dependent on local research settings. They often carry particular “social memories” with them and thus acquire important ethical implications.     

Children's Social Skills: Assessment and Classification Practices

After defining social skills, the authors review recent advances in the assessment and classification of children's social skills. Social skills have been demonstrated to be critical prerequisites to academic and interpersonal success. Therefore, knowledge of recent advances in the evaluation of social skills is essential to the functioning of counselors in schools.     

Grounding Rights in Social Practices: A Defence

This paper defends a social practiceconception of moral rights possession againstwhat many of its critics take to be a decisiveobjection, namely that such a conceptionprevents us from using moral rights forcritical purposes.     

Responsible Authorship in Engineering Fields: An Overview of Current Ethical Challenges

The primary aim of this article is to identify ethical challenges relating to authorship in engineering fields. Professional organizations and journals do provide crucial guidance in this realm, but this cannot replace the need for frequent and diligent discussions in engineering research communities about what constitutes appropriate authorship practice. Engineering researchers should seek to identify and address issues such as who is entitled to be an author and whether publishing their research could potentially harm the public.

当前考试理论研究的进展

近二十年以来,考试理论(Testing Theories)的研究取得了长足进展,这种进展表现在两个方面一方面,在上个世纪六十年代由Lord提出的项目反应理论(Item Response Theory,IRT)得到了很大的扩展,出现了多维度项目反应理论(multi-dimensional IRT)、非参数项目反应理论(Nonparametric IRT)以及认知诊断理论(Cognitively Diagnostic Theory)等;另一方面,项目反应理论在考试实践中得到了广泛的应用,使考试实践产生了革命性的变化,出现了计算机自适应考试(Computerized Adaptive Testing,CAT).     

Constructing Virtual Worlds: Tracing the Historical Development of Learner Practices

This study explores learning and instruction within a technology-rich, collaborative, participatory learning environment by tracking the emergence of shared understanding and products through student and teacher practices. The focus is not only on the interactions among students or between students and teachers, but on student-resource interactions, especially student-technology interactions. In a 1-week camp, students worked in activity groups with 3-dimensional modeling software to develop virtual worlds. Holistic accounts of 2 activity groups in the camp are presented, emphasizing the focus of the activity, group dynamics including the role of the teacher, and the historical development of learner practices. Then, a network methodology is used to trace the history of interactions accounting for the emergence, evolution, and diffusion of learner practices. The findings suggest that becoming knowledgeably skillful with respect to a particular practice or concept is a multigenerational process, evolving in terms of contextual demands and available resources. The tracings further reveal the reciprocal nature of learning and doing, with building conceptual understanding occurring in relation to local conditions and practices, and doing practices being a part of student learning.
