Ethics in Research

Summary

This article presents an overview of the history of efforts to protect human subjects in research. It discusses the establishment of international, national, organizational, and institutional procedures designed to protect human participants. The article provides a detailed summary of the principal ethical codes for research and their origins. It includes discussions of the most frequently encountered ethical issues ranging from the initial decision to undertake the project, through the selection and application of the various research procedures, to the analysis and interpretation of the data.     

Memory modulated saliency: A computational model of the incremental learning of target locations in visual search

The top-down guidance of visual attention is one of the main factors allowing humans to effectively process vast amounts of incoming visual information. Nevertheless we still lack a full understanding of the visual, semantic, and memory processes governing visual attention. In this paper, we present a computational model of visual search capable of predicting the most likely positions of target objects. The model does not require a separate training phase, but learns likely target positions in an incremental fashion based on a memory of previous fixations. We evaluate the model on two search tasks and show that it outperforms saliency alone and comes close to the maximal performance of the Contextual Guidance Model (CGM; Torralba, Oliva, Castelhano, & Henderson, 2006; Ehinger, Hidalgo-Sotelo, Torralba, & Oliva, 2009), even though our model does not perform scene recognition or compute global image statistics. The search performance of our model can be further improved by combining it with the CGM.     

Variable- and person-centered approaches to examining temperament vulnerability and resilience to the effects of contextual risk

Using both variable- and person-centered approaches, this study examined the role of temperament in relation to children’s vulnerable or resilient responses to cumulative risk. Observed reactivity and regulation dimensions of temperament were tested as mediating and moderating the relation between family cumulative risk and teacher-reported adjustment problems in a sample of 259 preschool-age children. Further, latent profile analyses were used to examine whether profiles of temperament, accounting for multiple characteristics simultaneously, provided additional information about the role of temperament in children’s responses to risk. Results support a diathesis-stress model in which high frustration, low fear, and low delay ability confer particular vulnerability for children in high-risk contexts. Benefits of multiple approaches are highlighted.     

企业组织变革特征、人力资源策略与变革应对行为的实验研究：组织学习的视角

在快速发展的全球化和知识经济背景下,各类组织急需通过变革创新来适应动态环境和开拓发展。本研究使用基于多案例的实验学习技术,研究与检验了公司组织变革的关键特征和人力资源策略与变革策略,特别关注了组织学习的关键作用。基于110项组织变革案例情节的内容分析,本研究验证了变革的四项主要特征：风险创新性、动态整合性、网络互动性和文化多样性。组织变革过程的有效人力资源策略包括培训发展、招聘配置和绩效薪酬。统计分析结果表明,组织绩效受到多重因素影响和组织学习的中介效应,而组织学习各个维度中,实验尝试学习的效应最显著。组织学习促进了两种变革策略的效能期望,即文化学习策略和团队协同策略。     

Acceptance and values-based action in chronic pain: a three-year follow-up analysis of treatment effectiveness and process

Recent developments in CBT emphasize the promotion of psychological flexibility to improve daily functioning for people with a wide range of health conditions. In particular, one of these approaches, Acceptance and Commitment Therapy (ACT), has been studied for treatment of chronic pain. While trials have provided good support for treatment effectiveness through follow-ups of as long as seven months, the longer-term impact is not known. The present study of 108 participants with chronic pain examined outcomes three years after treatment completion and included analyses of two key treatment processes, acceptance of pain and values-based action. Overall, results indicated significant improvements in emotional and physical functioning relative to the start of treatment, as well as good maintenance of treatment gains relative to an earlier follow-up assessment. Effect size statistics were generally medium or large. At the three-year follow-up, 64.8% of patients had reliably improved in at least one key domain. Improvements in acceptance of pain and values-based action were associated with improvements in outcome measures. A “treatment responder” analysis, using variables collected at pre-treatment and shorter term follow-up, failed to identify any salient predictors of response. This study adds to the growing literature supporting the effectiveness of ACT for chronic pain and yields evidence for both statistical and clinical significance of improvements over a three-year period.     

Beauty is in the sex of the beholder: An examination of the effects of interviewer characteristics on assessments of respondent attractiveness

Research exploring the effects of physical attractiveness frequently assesses attractiveness by employing subjective appraisals by independent raters. However, there is reason to believe that rater characteristics – especially their sex – may systematically bias subjective ratings of physical attractiveness. The current study explores this possibility by analyzing data from the National Longitudinal Study of Adolescent Health (N = 13,330). Analyses of these data revealed that ratings of physical attractiveness are significantly influenced by the sex of the interviewer/rater. Specifically, male raters were significantly less likely than female raters to assess males as attractive, very attractive, and very unattractive. The results are explained within the context of evolutionary psychology and illustrate a methodological concern for research on physical attractiveness.     

生产型企业的工作自主性:概念、测量与相关研究

工作自主性作为工作特征的关键指标,是指员工在工作方法、工作安排和工作标准上能自行控制与自行决定的程度;包括方法自主、安排自主和标准自主三方面,分别构成工作自主性量表的三个测量维度.诸多实证研究及相关研究综述表明,工作自主性对员工的工作态度和工作绩效等结果变量具有显著效应.同时,工作自主性对其他变量之间的关系具有调节作用.今后应多开展在中国情景中的验证性研究及干预性实验研究.
