Transformation and Closure for Anatomical Donor Families that Meet Medical Students

The University of Oklahoma College of Medicine has conducted an annual Anatomical Donor Luncheon where families of the anatomical donors met anatomy dissection groups of medical students. The luncheon presented an opportunity for donor family members to share the life story of their loved one with the medical students prior to the start of the anatomy course. This study was designed to understand the impact of the Anatomical Donor Luncheon on families of the donors. Seven families in two different focus groups were included to explore the reactions and attitudes of the donor families to meeting the medical students. Conversations were digitally recorded and transcribed. Qualitative analysis of textual data were coded by three investigators using the Constant Comparative Method. To provide evidence of validity, a form of member checking was utilized. For further triangulation, an analyst not involved in conducting the focus groups or analyzing the data, re-coded all data. This analyst used categories and themes identified by the original analysts, ensuring validity of the themes and any negative cases (data not supporting or contradictory of the established categories and themes). One meta-theme and three sub-themes were identified. The meta-theme was Donor Family Participants Experience Transformation and Closure, and sub-themes were Motivators for Participation, Optimal Venue Factors, and Optimal Medical Student–Anatomical Donor Family Interactions. Study findings indicated the Anatomical Donor Luncheon facilitated closure on the death of their loved one, and transformed their apprehension about the luncheon and body donation into an attitude of gratitude and appreciation.

情商理论在科技期刊编辑流程中的应用

随着社会的进步与发展,情商的重要性越来越引起人们的重视.在科技期刊的编辑流程中,编辑在与作者和审稿专家进行沟通和交流时,也应当注重情商理论的应用.编辑在不同的阶段,对不同的交流对象,应采用不同的交流方式,但都应以真诚和尊重为基础、有同理心、多进行换位思考,这样在获得对方肯定和认同的同时,也会得到对方的支持与信任.融洽的人际关系、高尚的职业道德、高度的责任感和良好的交流态度能够帮助编辑更好地发挥职业作用,实现职业价值,也更有利于期刊长期、健康、稳定的发展.     

Reexamining Fear Appeal Models from Cognitive Appraisal Theory and Functional Emotion Theory Perspectives

Recognizing inconsistencies between the extant fear appeal theories and emotion literature, this research integrated cognitive appraisal theory and functional emotion theory into a fear appeal literature and proposed a model that describes a process through which both fear and anxiety can contribute to adaptive responses. Findings from an experiment (N = 927) supported the predictions. Fear and anxiety emerged as distinct constructs. Perceived susceptibility was a stronger predictor of anxiety than fear, while perceived severity was a stronger predictor of fear than anxiety. In addition, greater fear and anxiety led to greater response efficacy through increased motivation to obtain protection-related information and heightened attention to such information, thus mediating the threat and coping appraisal processes. The SEM model testing the predictions showed that perceived susceptibility had the strongest total effects on protection intention, followed by anxiety, perceived severity, and fear.     

"科学发展观与媒介化社会构建"系列报告之三我国社会的媒介影响与媒介依赖

大众媒介的飞速发展使人类社会步入媒介化时代.如今,媒介已经成为人们社会政治生活和日常生活中不可缺少的东西,人们对大众传媒的依赖性越来越大.大众媒介具有巨大的影响,它缔造了人们所处的大众文化环境,制约了人们的认知与行为,这种无形的影响力被认为是产生媒介化的主要原因.伴随着媒介对社会无孔不入的渗透,受众对媒介的依赖也愈发增强,突出地表现为人对媒介的工具性依赖和内容依赖.     

家庭关系对流动儿童心理健康的影响

目前流动儿童的心理健康日益成为政策制定者和学者关注的焦点问题,而家庭环境是影响儿童心理健康的重要因素.本研究利用SDQ(Strengths and Diffficulties Questionaire)量表,通过OLS、Ordered Probit模型的回归分析,探析家庭关系(夫妻关系、亲子关系)对流动儿童心理健康状况的影响.结果发现,夫妻关系、亲子关系中的忽视、当着外面人的吼骂显著影响流动儿童的心理健康;家庭关系对儿童心理健康的不同维度(情绪症状、行为问题、多动注意不能、同伴交往)影响并不相同.此外,家庭社会经济地位(SES)与母亲受教育水平对流动儿童心理健康的影响并不显著,仅在特定维度有影响.农民工父母应正确处理好经济上的供养与精神上的抚慰之间的关系,努力提高自身教育能力,同时城市应实现公共服务的均等化,为流动儿童营造健康的成长环境.
