Positive and negative implications of two types of college-age narcissism on psychosocial functioning at midlife were studied in a longitudinal sample of women. Both types were scored with self-report measures when the women were, on the average, age 21. Throughout the first half of their adult life, high scorers on covert narcissism presented themselves as lacking in confidence and having low morale; high scorers on overt narcissism described themselves as wanting admiration, being independent, and being forceful. Positive outcomes associated with covert narcissism included the development of insight and of a differentiated sense of the self and, in the case of overt narcissism, entailed an involvement in high-status and creative work careers. At midlife, high scorers on covert narcissism experienced negative affect and feelings of being neglected, whereas high scorers on overt narcissism experienced family conflict and problems with impulse control. The personality characteristics associated with both types of narcissism remained stable from the early 20s to early 50s.  相似文献

There are approximately one million cases oftype 1 diabetes in the US, and the incidenceis increasing worldwide. Given that two-thirdsof cases present in childhood, it is criticalthat prediction and prevention research involvechildren. In this article, I examine whethercurrent research methodologies conform to theethical guidelines enumerated by the NationalCommission for the Protection of Human Subjectsof Biomedical and Behavioral Research, andadopted into the federal regulations thatprotect research subjects. I then offer twopolicy recommendations to help researchersdesign studies that conform to these ethicalrequirements.  相似文献

At the beginning of the nineteenth century, the idea of reason began to lose its universal and absolute value, undermining the view of science as a form of objective knowledge that reveals a fundamental reality. These changes have also had an impact on psychoanalysis, leading to a proliferation of theories and the end of a positivistic approach, epitomized by a 'neutral' analyst who knows the contents of the patient's mind. Hermeneutic philosophy provides a tool with which to explore both theoretical multiplicity and the contribution of the analyst's subjectivity to the analytic process. Furthermore, a hermeneutic approach does not have to be hostile to empirical science, but can be integrated with it in a 'scientific-hermeneutic model' in which historical and biological principles are given equal value.  相似文献

There is a large and growing body of research to show that human resource (HR) practices affect individual performance, organisational productivity and organisational performance. Academic findings about effective HR practices, however, have not readily been adopted by practitioners. A variety of theoretical and practical explanations have been advanced about the research–practice gap. Research by Rynes, Colbert, and Brown (2002) suggested that the research–practice gap is due to a lack of knowledge, but the extent to which these findings apply to the Australian context is unknown. The sample consisted of 102 industrial/organisational (I/O) psychologists and 89 HR practitioners. The main aim of the present study was to replicate and extend the work of Rynes et al. by examining and comparing the knowledge of I/O psychologists and HR practitioners. It was found that overall I/O psychologists were better informed about HR research than HR practitioners; in particular, they were more knowledgeable about management practices and recruitment and selection. In both groups, of the five content areas examined (Management Practices; General Employment Practices; Training and Development; Recruitment and Selection; and Compensation and Benefits), the greatest gaps were in Recruitment and Selection.  相似文献

本文通过系统分析产后抑郁领域的国内研究现状,为研制针对性的干预策略奠定基础。研究遵循循证医学的理念,运用文献计量分析方法,对国内1998年~2007年间发表的111篇产后抑郁领域的研究文献进行分析。可见研究文献数量呈现逐年上升趋势,但研究范围主要局限于医学中心及区域范畴,研究内容主要涉及产后抑郁的评估与诊断、危险因素研究和预防干预方法的探索,但总体研究设计存在较大缺陷。可见亟需加强社区层面研究,提高研究设计的科学性,并将预防干预方法研究作为重点。  相似文献

This article summarizes what is known about the active management of affective organizational commitment (AOC) through a review of 58 studies employing longitudinal research designs. The review yields six broad categories of antecedents that have empirically demonstrated effects on AOC: socialization practices, organizational changes, human resource practices, interpersonal relations, employee–organizational relations, and a residual “other” category. Insights from the review include (a) that perceptions of personal attachment to the organization are among the most substantiated (but tenuous) strategies for enhancing AOC, (b) that theorizing and research efforts have focused almost exclusively on achieving high levels of AOC, and (c) organizations have been reticent to address situations when AOC is low. Implications and recommendations for the theoretical, research and practical advancement of AOC are offered.  相似文献
