Stories can be a valuable tool for the career researcher. Questions arise, though, about how best to approach stories analytically such that their insights can be fully realised. In this paper I apply cultural theorist Raymond Williams’ analysis of cultural processes as dominant, residual and emergent (1977) to the narratives generated in a recent study into the careers of research scientists. I examine how these overlapping meaning systems are elucidated in individuals’ career narratives and consider implications for developing understanding.  相似文献

论公共卫生决策的伦理模式   总被引:1,自引:1,他引:0  
公共卫生决策的伦理问题是公共卫生伦理研究的一个核心问题。近年来我国公共卫生领域出现了大量严重的伦理问题,其主要根源在于公共卫生决策的伦理缺失。强调指出公共卫生伦理决策应当树立科学健康观,并以此为基础,从转变政府职能、强化公共卫生信息系统和加大政府投入等方面详细论述了公共卫生伦理决策的一种新模式。  相似文献

We analyze recently proposed decision rules for three-class classification from the point of view of ideal observer decision theory. We consider three-class decision rules proposed by Scurfield, by Chan et al., and by Mossman. Scurfield's decision rule is shown to be a special case of the three-class ideal observer decision rule in three different situations. Chan et al. start with an ideal observer model and specify its decision-consequence utility structure in a way that causes two of the decision lines used by the ideal observer to overlap and the third line to become undefined. Finally, we show that, for a particular and obvious choice of ideal-observer-related decision variables, the Mossman decision rule cannot be a special case of the ideal observer decision rule. Despite the considerable difficulties presented by the three-class classification task, the three-class ideal observer provides a useful framework for analyzing a variety of three-class decision strategies.  相似文献

The necessity of retrieving complex attribute information from long‐term memory has been shown to elevate processing costs and boost the use of simple decision heuristics. This effect was confined to verbal as opposed to pictorial attribute information. In a large‐scale experiment (N = 151), either verbal or pictorial information for inferences had to be retrieved from long‐term memory. Concurrent secondary tasks either interfered with the Central Executive, the Phonological Loop, or the Visuo‐Spatial Sketchpad. These are hypothetical components of working memory responsible for processing different information formats. Whereas the information format massively affected strategy selection, there was an additive rather than interactive effect of secondary task, suggesting enhanced retrieval costs irrespective of the information format. An additional analysis in terms of a similarity match as proposed by exemplar‐based models did not enhance the explanation of the data. Copyright © 2006 John Wiley & Sons, Ltd.  相似文献

ABSTRACT— Decision making often occurs in the face of uncertainty about whether one's choices will lead to benefit or harm. The somatic-marker hypothesis is a neurobiological theory of how decisions are made in the face of uncertain outcome. This theory holds that such decisions are aided by emotions, in the form of bodily states, that are elicited during the deliberation of future consequences and that mark different options for behavior as being advantageous or disadvantageous. This process involves an interplay between neural systems that elicit emotional/bodily states and neural systems that map these emotional/bodily states.  相似文献

为了比较分析保乳术和根治术的治疗成本和对乳腺癌患者预后的影响,从2002年1月~2005年6月湘雅医院乳腺科的乳腺癌资料库中,随机抽取64例I~II期乳腺癌分为保乳治疗组(A组,32例)和根治术组(B组,32例),并随访。结果显示,A、B两组全部药品费用分别平均为32474.11±16126.00元、35107.30±19352.71元,总费用平均为53959.64±22033.28元、53382.10±24042.87元。两组药品费和总费用均无统计学差异(P=0.556、0.921)。中位随访时间30个月,两组病例均无局部复发。A、B组远处转移率分别为6.25%、9.38%,两组无明显差异(P=0.641);Kaplan-Meier生存分析表明A、B组生存率分别为96.88%、93.75%,两组无显著性差异(P=0.4566)。保乳术患者对残乳的满意率为90.61%,认为保留了乳房后其对家庭和社会生活仍充满自信的分别占75%和87.5%;相反,根治术者仅占28.13%和40.63%;A、B两组有显著性差异(P=0.000、0.000)。由此得出结论,保乳术和根治/改良根治术两种治疗方法对I~II期乳腺癌患者的预后无差异,成本亦无明显区别,而保乳术明显提高了患者的家庭、社会生活质量。  相似文献

正确、合理的临床决策为病人提供理想的诊疗方案。在急诊室濒死病人的诊治过程中,急诊医生应本着以人为本的原则,根据病情的轻重缓急,抓住重点进行紧急处理。其中,病人疾病的性质与预后、疾病严重程度、医生技术水平、医院护理水平、医院的医疗设备与管理水平、诊治费用、医患关系、家属对待诊治的态度、医德医风、政策法规等对医生的临床诊治决策均有不同程度的影响。  相似文献

大学生择业心理归因结构研究   总被引:1,自引:0,他引:1  
施章清  孙昕怡 《心理科学》2006,29(3):665-667
为了解大学生择业心理,根据归因理论编制了“大学生择业心理归因问卷”。该问卷包括原因源与可控性两个分量表。通过对596名大学生进行问卷调查,对该问卷的项目进行了筛选和修订,最后共保留了20个项目。研究结果表明:(1)分量表一可抽取负性情绪与择业目标两个因子,分量表二可抽取自身努力与社会支持两个因子;(2)问卷的信度与效度都达到了测量学的基本要求。  相似文献

In this study, we translated and localized the Adult Decision‐making Competence scale (A‐DMC) and tested its reliability and validity with large samples. Results show the Chinese A‐DMC has relatively good reliability (Cronbach's alpha above 0.6 and test–retest reliability coefficients ranging from 0.44 to 0.78 on all subscales), comparable with the original version. Regarding validity, results of exploratory factor analysis and confirmatory factor analysis support the one‐factor model, indicating the A‐DMC has good internal consistency and construct validity. A‐DMC scores correlated positively with cognitive ability, constructive decision‐making styles, and good decision outcomes. Additionally, individuals with higher A‐DMC scores were found to perform better on the Cambridge gambling task and Iowa gambling task. These results confirm the validity of the Chinese version of the A‐DMC, which is suitable for measuring decision‐making competence in Chinese adults.  相似文献
