Gender related changes of work values were analyzed in a longitudinal questionnaire study of 173 male and 48 female engineers and 353 female and 31 male nurses at three measurement occasions covering about four and half years from the end of their vocational education. At all occasions, Social relations were rated as more important by women than by men and Altruism was given higher ratings by the nurses than by the engineers. Within both occupations women's mean Altruism ratings were higher than men's mean ratings, and in all groups except male engineers the mean ratings dropped between the three occasions. Women's ratings of Benefits and career and Influence were strengthened in both occupations, thereby eliminating an initial gender difference. The stability of work values is discussed in terms of challenges and norms in working life.  相似文献

The ability of welfare-to-work clients to leave the welfare rolls and stay in the labor force is often limited by the work barriers they face. Using a sample of 1,404 female welfare-to-work clients we first examined the structure of work barriers and then tested their contribution to current work status in the context of a structural equation model that incorporated other central pathways to employment. Whereas work barriers included diverse factors ranging from lack of transportation to low quality jobs, they were shown to constitute a uni-dimensional construct. Furthermore, work barriers had a net adverse effect on employment outcomes, controlling for job search self-efficacy and employment intention. We conclude with discussion of implications for the development of welfare-to-work programs and interventions that target low-income women.  相似文献

Ⅱ型糖尿病人认知功能特点   总被引:7,自引:0,他引:7  
综述了近10国内外关于Ⅱ型糖尿病人认知功能特点的研究。结果表明:(1)流行病学筛查因天花板效应难以发现认知损伤。(2)采用对年老化较敏感的行为学指标证实,60~70岁的糖尿病人认知能力显著低于对照组;但60岁以下或70以上病人则少有类似表现。认知阈限理论可解释这一年龄相关现象。(3)Ⅱ型糖尿病人认知功能损伤主要表现为语词记忆损伤、学习能力下降、脑电(P300)潜伏期延长等。(4)认知损伤程度与血糖和胰岛素水平相关,也受高血压等共病因素的影响。控制糖代谢可改善认知功能。糖尿病人的认知损伤与年龄相关,但其机制不同于正常年老化过程中的认知衰退  相似文献

For ten years, 1971–1981, the Institute onHuman Values in Medicine (IHVM) played a keyrole in the development of Bioethics as afield. We have written this history andanalysis to bring to new generations ofBioethicists information about the developmentof their field within both the humanitiesdisciplines and the health professions. Thepioneers in medical humanities and ethics cametogether with medical professionals in thedecade of the 1960s. By the 1980s Bioethics wasa fully recognized discipline. We show the rolethat IHVM programs played in defining thefield, training faculty and helping schools todevelop programs. We review the beginnings ofthe IHVM in the crucible of social andtechnological change that led to theestablishment of the IHVM's parentorganization, the Society for Health and HumanValues. We then turn to the IHVM programsthrough which Faculty members receivedfellowships to explore new crossovers betweenthe humanities and the health professions. Wehave not only described the Fellows Program asit existed in 1973–1980, but have completed asurvey of the fellows a quarter of a centuryafter they held their fellowships. We describeother IHVM programs designed to facilitate theinitiation and development of new humanitiesprograms, to explore conceptual issues betweenmedicine and five humanities fields, to conductissue driven or educational method conferencesand to advance humanities programs intograduate education through the Directors ofMedical Education.  相似文献

In mid‐June 2009, the Obama administration dissolved the President's Council on Bioethics (PCBE), a group established by President George W. Bush in August 2001 and whose nearly eight‐year life was marked from beginning to end by controversy. While some will regret the PCBE's passing, others will regard the Council as a failed experiment in doing public bioethics.  相似文献

独生与非独生儿童认知发展的比较研究(广州市)   总被引:1,自引:0,他引:1  
为了研究中国独生子女政策可能造成的独生和非独生儿童的认知能力的差别,分别在广州七所小学一年级和五年级中选择了146名和171名独生与非独生儿童。用11项认知能力测验对这些儿童进行测查。一年级独生儿童在言语记忆和一般常识项目上的成绩优于非独生儿童。研究认为,一年级独生儿童在与一般认知能力有关的项目上具有优势。而五年级的独生儿童在认知作业成绩上,没有表现出显著性的优势。另外,独生男童在一般常识方面优于独生女童。作者用独生儿童受到较大的父母关注和投资来解释一年级独生对非独生儿童在认知方面的优势。随着儿童的自然成熟和学业教育,两者之间的差距会逐渐缩小,从而使五年级独生儿童未能在认知方面表现出明显的优势。  相似文献

Deterministic Chaos: Some Interesting Points of View from the Philosophy of Science. A comparatively simple example is used to present some of the main features of deterministic chaos. From the point of view of the philosophy of science, three questions are dealt with: if the equations of motion of chaotic systems are falsifiable in a strict sense; whether experiments on chaotic systems are reproducible; to what extent the development of chaotic systems is predictable. It emerges that in these respects chaotic systems, though being deterministic, behave essentially in the same way as stochastic (indeterministic) systems do.  相似文献

This paper provides a Genzten style formulation of the game logic framework GLm (0 m ), and proves the cut-elimination theorem for GLm. As its application, we prove the term existence theorem for GL used in Part I.  相似文献
