Measuring work styles: Towards an understanding of the dynamic components of the theory of work adjustment

Work styles are an important yet largely unexplored component of the theory of work adjustment (TWA), describing a dynamic component of how individuals maintain and adjust fit with their work environment. The active work style (AWS) scale is the first attempt to develop a specific self-report measure of work styles suitable for longitudinal research. Results from three studies support Dawis and Lofquist's (1984) proposed four factor structure, but these factors are related through a second-order factor describing a person's generalised level of work activity and effort across time. The AWS scale demonstrated good evidence for reliability and validity, and strong measurement invariance across time signifying its suitability for longitudinal research. In line with expectations, overall work style was positively related to conscientiousness and work engagement yet unrelated to stress. When controlling for these variables, AWS was positively related to demands–abilities fit, but not needs–supplies fit. Limitations and possibilities for future research are also discussed.     

Evaluating Arguments Based on Toulmin’s Scheme

Toulmin’s scheme for the layout of arguments (1958, The Uses of Argument, Cambridge University Press, Cambridge) represents an influential tool for the analysis of arguments. The scheme enriches the traditional premises-conclusion model of arguments by distinguishing additional elements, like warrant, backing and rebuttal. The present paper contains a formal elaboration of Toulmin’s scheme, and extends it with a treatment of the formal evaluation of Toulmin-style arguments, which Toulmin did not discuss at all. Arguments are evaluated in terms of a so-called dialectical interpretation of their assumptions. In such an interpretation, an argument’s assumptions can be evaluated as defeated, e.g., when there is a defeating reason against the assumption. The present work builds on recent research on defeasible argumentation (cf. e.g. the work of Pollock, Reiter, Loui, Vreeswijk, Prakken, Hage and Dung). More specifically, the author’s work on the dialectical logic DEFLOG and the argumentation tool ARGUMED serve as starting points.     

情绪作为道德判断的“催化剂”：道德判断中的评价倾向与特异性效应

在不同领域的道德判断中,情绪可能起着“催化剂”的作用。一种特定情绪对应一种核心评价;一种情绪只影响某一道德领域的判断,不同情绪的影响是特异性的;进化心理学和具身认知对道德判断中存在的评价倾向和特异性效应进行了解释。未来研究需要探索评价倾向与特异性效应的内在心理机制。以及进一步探讨文化等第三变量对不同情绪与特定领域道德判断的影响。     

混合模式调查下的测量不变性：跨文化视角

混合模式调查收集数据的有效性需以模式间测量等同为前提.以往调查模式间的测量等同研究尚未考虑文化因素的影响.本研究通过两个自我创新能力评价量表,基于中美两国数据,运用多组确认性因子分析法考察了将由网络调查和纸笔调查构成的混合调查模式应用于自我能力和行为评估时的测量等同问题.结果在美国的样本中发现创新能力评价量表在两种调查模式下具有测量不变性,而在中国的样本中只发现强因子测量不变性,提示混合模式调查下测量不等同的出现是调查模式和文化因素共同导致的结果.我们认为,集体主义文化扩大与强化了纸笔调查和网络调查之间的匿名感知差异,进而受访者可能在网络调查中呈现出“满意决策”作答行为或在线下的调查中呈现出“社会称许性作答行为”,从而增加了出现测量不等同的可能性.     

Faith,Fact, and Behaviorism

David Hume argued that ought cannot be derived from is. That is, no set of facts, no amount of scientific knowledge, is by itself sufficient to urge us to action. Yet generations of well-meaning scientists (more and more as secular influences grow in the West) seem to have forgotten Hume''s words of wisdom. All motivated action depends ultimately on beliefs that cannot be proved by the methods of science, that is, on faith.     

How Much Distress Is Too Much on Deployed Operations? Validation of the Kessler Psychological Distress Scale (K10) for Application in Military Operational Settings

The aim of this study was threefold: (a) to assess the factor structure of the Kessler Psychological Distress Scale (K10) to determine whether interpreting the scale as a single dimensional measure of psychological distress is justified in military operational setting; (b) to validate the K10 for mental health surveillance in operational settings against self-reported occupational impairment; (c) to evaluate whether the K10 has better discriminatory power than de facto standards for mental health surveillance on deployment, namely the Patient Health Questionnaire and the Posttraumatic Stress Disorder Checklist, Civilian version. A convenience sample of Canadian Armed Forces personnel serving in Afghanistan (N = 1,264) completed self-report measures of psychological distress and occupational impairment. On examination of 6 competing models, the authors determined that interpreting the K10 as a measure of unspecified psychological distress is justified. Using receiver operating characteristic (ROC) curve analysis, they identified new cutoff values for dichotomous and polychotomous scoring methods. After comparing the area beneath the ROC curves for each of the 3 mental health surveillance questionnaires, the authors determined that all measures perform well as predictors of self-rated occupational impairment, with values ranging from .86 to .90. These results highlight the importance of cross-setting validation and demonstrate that validating psychological screening questionnaires against self-report measures of occupational impairment can be a useful strategy for understanding the manifestation of psychological distress on deployed military operations.     

Regional brain activity change predicts responsiveness to treatment for stuttering in adults

Developmental stuttering is known to be associated with aberrant brain activity, but there is no evidence that this knowledge has benefited stuttering treatment. This study investigated whether brain activity could predict progress during stuttering treatment for 21 dextral adults who stutter (AWS). They received one of two treatment programs that included periodic H₂¹⁵O PET scanning (during oral reading, monologue, and eyes-closed rest conditions). All participants successfully completed an initial treatment phase and then entered a phase designed to transfer treatment gains; 9/21 failed to complete this latter phase. The 12 pass and 9 fail participants were similar on speech and neural system variables before treatment, and similar in speech performance after the initial phase of their treatment. At the end of the initial treatment phase, however, decreased activation within a single region, L. putamen, in all 3 scanning conditions was highly predictive of successful treatment progress.     

Toward a Reconstruction of Medical Morality

At the center of medical morality is the healing relationship. It is defined by three phenomena: the fact of illness, the act of profession, and the act of medicine. The first puts the patient in a vulnerable and dependent position; it results in an unequal relationship. The second implies a promise to help. The third involves those actions that will lead to a medically competent healing decision. But it must also be good for the patient in the fullest possible sense. The physician cannot fully heal without giving the patient an understanding of alternatives such that he or she can freely arrive—together with the physician—at a decision in keeping with his or her personal morality and values. In today's pluralistic society, universal agreement on moral issues between physicians and patients is no longer possible. Nevertheless, a reconstruction of professional ethics based on a new appreciation of what makes for a true healing relationship between patient and physician is both possible and necessary.     

Exploring the determinants of dual goal facilitation in a rule discovery task

Wason's standard 2-4-6 task requires discovery of a single rule and leads to around 20% solutions, whereas the dual goal (DG) version requires discovery of two rules and elevates solutions to over 60%. We report an experiment that aimed to discriminate between competing accounts of DG facilitation by manipulating the degree of complementarity between the to-be-discovered rules. Results indicated that perfect rule complementarity is not essential for task success, thereby undermining a key tenet of the goal complementarity account of DG facilitation. The triple heterogeneity account received a good degree of support since more varied triple exploration was associated with facilitatory DG conditions, in line with this account's prediction that task success is associated with the creative search of the problem space. The contrast class account (an extension of Oaksford & Chater's, 1994, iterative counterfactual model) was also corroborated in that the generation of descending triples was demonstrated to be the dominant predictor of DG success. We focus our discussion on conceptual ideas relating to the way in which iterative counterfactual testing and contrast class identification may work together to provide a powerful basis for effective hypothesis testing.     

"旧人"的否弃和"新人"的形塑--论马克思对人的价值形象的设计

任何关于人的理论都有自己理想的人的价值形象。它既是观察和评价现实生活的标准,也是实践活动所追求的目标。本文旨在将马克思所设计的人的价值形象从他复杂的理论构造中剥离出来。马克思关于人的理论以批判性的建构为鲜明特色,他对理想的人的价值形象的设计跟他对人的实际生活状况的否定是相辅相成的,亦即对“旧人”的否弃和对“新人”的塑形是同时进行的。这个“新人”的主要内涵如下：人应该是民主制度下的人。应该是追求现实幸福的人,应该是自由地自觉地活动的人,应该是全面发展的人。
