生涯适应力的作用：个体与组织层的跨层面分析*

生涯适应力(career adaptability)是生涯建构理论提出的自我职业生涯管理的核心概念,但国外理论和实践一直认为生涯适应力是一把双刃剑(生涯适应力高的员工工作绩效高,但其离职意向也高),本研究将对此进行检验;同时,生涯适应力作为个体职业生涯开发的核心变量,它在组织职业生涯管理跨层面作用中的价值也未曾研究。通过员工在两个时间点自评和管理者他评问卷,获得54家单位的485份有效调查问卷。结构方程模型分析的结果表明,生涯适应力不仅与工作绩效有显著正相关,而且也与离职意向有显著负相关。层次回归分析结果表明,工龄是生涯适应力与离职意向、工作绩效关系的调节变量;也就是说,工龄短员工的生涯适应力与工作绩效呈显著正相关,与离职意向呈显著负相关,但工龄长员工的生涯适应力与二者的关系都不显著。基于跨层面研究设计,多层线性模型(HLM)分析的结果表明,生涯适应力是组织职业生涯管理与个体工作绩效之间的完全中介变量,但在组织职业生涯管理与离职意向之间的中介作用不显著。这不但回答了生涯适应力对组织价值的管理困境问题,也解决了组织职业生涯管理与个体工作绩效的连接纽带问题。     

THE FIRST ‘DESIGNER BABY’: The Role of Narratives,Cliche´s and Metaphors in the Year 2000 Media Debate

The public do not like, and we do not like the idea of designer babies (Ruth Deech, then Chair of the Human Fertilisation and Embryology Authority, quoted in The Independent, 18 October 2000). We are all on the slippery slope-the question we should be asking is: skis or crampons (Professor John Harris, The Centre for Social Ethics and Policy, University of Manchester, in an interview with Susan Johnson). LINGUISTIC AND CULTURAL GROUNDING OF THE DESIGNER BABY DEBATE In October 2000, news was released of the world’s first ‘designer baby’—Adam Nash who was born on 29 August 2000 in the United States. He was chosen as a donor for his sister Molly, who suffered with Fanconi Anaemia, which is a rare genetic disease. Without a bone marrow transplant, Molly would have died before the age of 10. A suitable donor had not been found, so her parents decided to undergo in vitro fertilization (IVF), and preimplantation genetic diagnosis (PGD) to select an embryo that would not carry the disease-causing gene and would become a brother and a donor for Molly. At the time of his birth, Adam’s cord blood was collected and later transplanted into his sister. Initial reports suggest that the treatment has been successful.     

医患共同决策诊疗模式的现状分析

医患共同决策诊疗模式已经践行了许多年.系统检测,卓有成效.但是,在实践过程中仍然有很多问题存在.尽管许多医生认为自己已经使用了共同决策,但是研究显示出现实与感知的差异.由于我们的决策面对的是需要治疗的患者,而患者是存在个体差异的;同时,医学知识和技术是在不断发展和进步的,所以医生需要改变传统的决策方式,重视医学证据、可用资源和患者的价值取向.     

个体化喉部分切除术的思考

喉癌以手术为主要治疗方式,在现代功能性外科治疗理念的指导下,个体化喉部分切除术已被提出并逐渐推广应用,本文就这一术式展开哲学思考,认为个体化喉部分切除术提出及应用中遵循的哲学规律包括:矛盾对立统一规律;矛盾普遍性与特殊性规律;主要矛盾与次要矛盾关系的规律.     

胃肠道肿瘤的分子靶向治疗:未来的方向?

分子靶向治疗是这几年来消化道肿瘤治疗领域的热门话题.这类新一代的分子靶向生物治疗模式,将在临床治疗肿瘤实践中具有广阔的应用前景.从事肿瘤研究的临床医务人员需要综合归纳这些信息,融汇入自己的认知将之合理应用于患者.我们将真正进入传统的细胞毒性药物攻击与非细胞毒性靶向性药物相结合使用的时代,真正实现延长患者的生命,改善其生活质量的目标.     

糖尿病与乳腺癌关系研究进展

近年来随着生活水平的提高,饮食结构的改变,糖尿病的发病率不断升高,其并发症严重危害人们的健康.对于女性来说,乳腺癌发病率已上升为危害女性健康的首位恶性肿瘤,给女性带来了严重的心理压力.糖尿病与癌症相关性研究逐渐引起重视.有研究表明,糖尿病会增加乳腺癌的发病率,但也有研究表明二者之间的关系存在争议,所以需要进一步的流行病学调查研究.本文对近年来关于糖尿病与乳腺癌关系的流行病学调查以及糖尿病与乳腺癌之间可能的作用机制作一综述.     

间隔时间及记忆负荷对信息缺失错误记忆的影响

现场中的信息缺失会影响人类对事件的记忆,这对证人证言研究是非常重要的,但以往对之却鲜有研究.本研究以大学生为被试,运用信息缺失范式,采用视频录像材料,通过2个实验探讨了间隔时间和记忆负荷对错误记忆的影响.结果表明:(1)间隔时间没有影响真实记忆和错误记忆,但信心水平却随着间隔时间的延长而变化;(2)记忆负荷高低没有影响真实记忆却影响了错误记忆,在关键信息呈现条件下,降低记忆负荷可以减少错误记忆的发生;(3)信息性质会影响人们的记忆,关键信息呈现条件下的错误记忆和真实记忆均高于关键信息缺失的条件.     

Motivational Profiles and Psychological Skills Use within Elite Youth Sport

This study investigated associations between achievement goal orientations and reported psychological skill use in sport. Five hundred seventy three elite young athletes completed the Perceptions of Success Questionnaire (POSQ; Roberts, Treasure, & Balague, 1998 Roberts, G. C., Treasure, D. C. and Balague, G. 1998. Achievement goals in sport: The development and validation of the Perceptions of Success Questionnaire. Journal of Sport Sciences, 16: 337–347. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) and the Test of Performance Strategies (TOPS; Thomas, Murphy, & Hardy, 1999 Thomas, P. R., Murphy, S. M. and Hardy, L. 1999. Test of performance strategies: Development and preliminary validation of comprehensive measure of athletes' psychological skills. Journal of Sports Sciences, 17: 697–711. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]). Cluster analysis revealed three distinct goal profile groups: Cluster 1—Higher-task/Moderate-ego (n = 260); Cluster 2—Lower-task/Higher-ego (n = 120); and Cluster 3—Moderate-task/Lower-ego (n = 119). A MANOVA revealed a significant multivariate effect, Pillai's Trace = .11, F(16, 1076) = 3.75, p = .001, η² = .05, with post hoc tests determining that higher-task/moderate-ego athletes reported using significantly more Imagery, Goal setting, and positive Self-talk skills when compared with Lower-task/Higher-ego and/or Moderate-task/Lower-ego athletes. These findings are discussed with respect to the potential role that achievement goals play in the application and development of psychological skills in youth sport.
