Associations amongst disease severity,religious coping and depression in a cohort of Jamaicans with sickle-cell disease

The purpose of this study was to investigate the relationship between disease severity (sickle-cell type and hospital, emergency room and clinic emergency visits (CEU)), religious coping (positive and negative) and depression. This was accomplished through secondary analysis of a data set based on a Comprehensive Sickle Cell Standardized Questionnaire compiled by a multidisciplinary team of professionals from Duke University Medical Centre, and administered to persons with sickle-cell disease being treated at the Sickle Cell Unit on the University of the West Indies Campus between November 2008 and January 2009. Disease severity was not a good predictor of depression within the population. On the other hand, depression was found to correlate with positive and negative religious coping, such that increases in the former were associated with decreases in depression scores; while the reverse was noted for the latter (negative religious coping). The results shed light on issues that could possibly impact the treatment plan for such individuals.     

Qualitative elicitation of affective beliefs related to physical activity

ObjectivesBased on previous research that has identified affective attitude as a distinct predictor of physical activity (PA) behavior, the purpose of this pilot study was to elicit affective beliefs toward physical activity using qualitative data generated through specific open-ended questions.MethodsA sample of 126 undergraduate students participated in this study. Four open-ended questions based on the theory of planned behavior were posed to elicit affective beliefs. A content analysis was used to categorize and code data by theme based on common responses that emerged in the elicitation. A frequency count of the responses falling into each category was then conducted to establish which affective beliefs were the most common. The themes were established by two researchers and reviewed for internal homogeneity and external heterogeneity by a third party.ResultsThe results highlight key beliefs related to affective attitude. In descending rank order; Social Involvement, Pleasant Body States, Esteem, Improved Psychological Outcome, and General Enjoyment were the most common affective beliefs for PA involvement. Feelings arising from Time Issues/Conflict, Physical Unpleasantness, PA Environment, and Necessity/Obligation were the most common negative affective beliefs.ConclusionsThe results suggest that promoting enjoyment rather than necessity of PA and encouraging variety in PA may be effective. Addressing the importance of aesthetically pleasing environments and highlighting social interaction as a strategy rather than merely a norm or a form of support in behavioral research may be important.     

无医学指征剖宫产的影响因素及对策

无医学指征剖宫产是造成高剖宫产率的一个重要原因,也是公共卫生和全世界医疗机构关注的问题。事实上,许多潜在因素包括社会人口学、传统文化、家庭、法理及医源因素在无医学指征剖宫产形成中发挥了重要作用,并加剧了无医学指征剖宫产这一现象出现。更重要的是,通过构建和谐医疗环境、提高无痛分娩率、加强妊娠期健康宣教、规范产科管理、优化分娩环境和增加人文关怀等合理干预可有效降低无医学指征剖宫产。期望为卫生政策制定、临床指南和促进该领域未来的临床实践提供有意义的参考。

     

企业组织变革特征、人力资源策略与变革应对行为的实验研究：组织学习的视角

在快速发展的全球化和知识经济背景下,各类组织急需通过变革创新来适应动态环境和开拓发展。本研究使用基于多案例的实验学习技术,研究与检验了公司组织变革的关键特征和人力资源策略与变革策略,特别关注了组织学习的关键作用。基于110项组织变革案例情节的内容分析,本研究验证了变革的四项主要特征：风险创新性、动态整合性、网络互动性和文化多样性。组织变革过程的有效人力资源策略包括培训发展、招聘配置和绩效薪酬。统计分析结果表明,组织绩效受到多重因素影响和组织学习的中介效应,而组织学习各个维度中,实验尝试学习的效应最显著。组织学习促进了两种变革策略的效能期望,即文化学习策略和团队协同策略。     

Age-related differences in attentional networks of alerting and executive control in young, middle-aged, and older Chinese adults

Previous studies suggest that aging is associated with impairment of attention. However, it is not known whether this represents a global attentional deficit or relates to a specific attentional network. We used the attention network test to examine three groups of younger, middle-aged, and older participants with respect to the efficiency of three anatomically defined attentional networks: alerting network, orienting network, and executive control network. Age-related change was found to have the greatest effect on the executive network and the least effect on the alerting network as well as on overall mean response time. Impairment of the orienting network was found to be insignificant. Age-related deterioration of the prefrontal lobe, the dopaminergic system, and function of specific genes may explain the age-related changes in executive attention, which occur after the fourth decade of life.
