当代中国医患关系的合理重构--论我国社会转型期医患利益的调节与平衡

我国社会转型,为当代中国医患关系的合理重构提供了平台,但社会转型期中出现的诸多医患利益冲突也向人们提出了严峻的挑战,亟需对其加以调节和平衡.这种调节与平衡,不能完全甚至不能主要地交由市场这双"看不见的手"去运作,不能完全任凭甚至不能主要地任凭医患双方自由地去博弈;政府必须明确并履行自己的职责,为正确调节与平衡我国社会转型期的医患利益创立一个全方位的合理的框架,使医患之间在有控制的理性的双赢的利益博弈中合理地重构当代中国医患关系的基本格局.     

Peer rejection, negative peer treatment, and school adjustment: Self-concept and classroom engagement as mediating processes

Data gathered from a short term longitudinal study within fifth grade classrooms (n = 378) were used to evaluate two process-oriented models linking peer rejection and negative peer treatment to children's self-concept, school engagement and adjustment. Both structural models linked peer rejection, victimization, and exclusion to children's self-concept, classroom engagement, and change in achievement (fall of fifth grade to the spring). The model evaluations indicated that peer rejection predicted both exclusion and victimization and that these forms of peer treatment, in turn, predicted academic self-competence. Academic self-competence, however, only partially mediated linkages to achievement change. Parallel (i.e. direct) linkages from exclusion and victimization to both academic self-competence and engagement were required for adequate model fit, as were direct links from academic self-concept and engagement to achievement change. An alternative model representing the hypothesis that academic self-concept fully mediated the relationships between the forms of negative peer treatment and children's engagement and achievement did not fit the data well.     

自我理论研究及其对教育的启示

自我理论是指人们关于自我的信念体系或内隐理论。德韦克等人自20世纪60年代末开始系统研究自我理论对人的认知、情感与行为的影响及其发生发展的机制,并构建了基于自我理论的动机模型。本文试图对其研究成果做一简要介绍,并浅析自我理论研究成果对教育工作的启示。     

反馈干预的内部机制研究

基于龙君伟的反馈干预作用的内部机制模型,本实验研究发现反馈效价、反馈提供方式及其交互作用对自我效能感、应对策略、内部目标三种内部调节变量具有主效应;三种内部调节变量之问存在显著的正相关,并对绩效具有显著积极效应。在实际的应用中,反馈干预如能使个体采取趋向型的应对策略、增强自我效能感、提高内部目标设置水平,就能有效地提高个体的绩效水平。     

角色目标对空间维度非线索更新的影响

采用实时窗口阅读技术,探讨文本阅读中角色目标在情境模型空间维度非线索更新中的作用。实验一结果表明,阅读中。如果文本叙述中的角色在一个目标指引下展开活动．那么可以促进相应空间设置内的物体的更新。实验二考察了不同性质的角色目标在空问信息加工中的作用,结果发现,相对于已经达成的目标,未达成的目标对情境模型空间维度非线索更新的影响更大。     

一个基于综合印象评分法的作文分事后调整模型

对大学英语四、六级考试作文评分进行了详细的描述,重点介绍了作文分的事后调整的原理和方法,并且给出了一个基于线性等值原理的数学推导。认为其数学模型主要是一个运用了“极大似然估计法”和“正态分”概念的统计模型。“评分标准的制定”、“用参照样卷来校准阅卷员对作文评分标准的掌握尺度”以及“阅卷员的培训和考核”构成了大学英语四、六级考试作文信度的基石;而作文分调整中基于“随机分发作文卷”、“客观题分数与作文分相关”以及“评分前后一致性”的统计方法则对出现系统性误差的阅卷员的评分结果进行了事后的校正。还提出如果拥有往次考试总体作文分均值数据,使用“加权移动平均法”可以实现对作文分的跨考次平衡。     

How does preference reversal appear and disappear? Effects of the evaluation mode

Preference reversal is a systematic change in the preference order between options when different response methods are used (e.g., choice vs. judgment). The present study focuses on procedures used to elicit preferences according to an evaluability hypothesis. Two experiments compared joint vs. separate evaluations and explicit vs. non‐explicit joint evaluations. Subjects had to express preferences between high‐variance gambles (HVGs) and low‐variance gambles (LVGs) either by choosing one gamble to play in a lottery or by assigning gambles minimum selling prices. We show that HVGs are preferred in both choice and pricing conditions when gambles are evaluated separately, and LVGs are preferred in both choice and selling conditions when gambles are evaluated in pairs: i.e., when the evaluation mode is held constant, classic preference reversal disappears. These results support the evaluability hypothesis, and suggest that preferences depend on whether subjects are allowed to compare the options they are asked to choose from or judge, independently of the nature of the scale (i.e., attractiveness vs. minimum selling price) they are required to adopt.

工作中心度的作用及其与领导行为的关系研究

本研究在理论分析的基础上,探讨了工作中心度对职业生涯规划的作用,并进一步分析了以工作中心度为因变变量(contingent variable)的领导行为的有效性。通过问卷调查法对233位企业员工进行测量。结果发现:工作中心度高的员工对于他们的职业生涯会有更好的规划;应根据员工不同程度的工作中心度采取不同的领导行为,后者有利于员工更好地规划自己的职业生涯。     

国外目标承诺研究进展

成就目标定向与学习策略、学业成绩的关系研究综述

成就目标理论整合了曾经分离的动机研究和认知研究,是社会认知取向在动机领域中的代表性课题。文章对近十年国内外成就目标定向与学习策略、学业成绩的关系研究进行了综述,认为研究所取得的成果加深了我们对学习内在机制的理解。同时,作者也提出了这一领域应改进测量工具、进行重复验证、跨文化研究以及干预研究的主张。
