基于SET和TAM的消费者在线评论的动因研究

基于SET和TAM,文章从社会-心理和技术的角度构建了消费者在线评论动因的影响因素模型,利用Amos22.0软件使用极大似然估计法就感知有用性、感知易用性、经济报酬、情感分享、评论成本、感知乐趣对消费者在线评论动因的影响进行研究。研究结果表明:感知有用性、经济报酬、情感分享显著影响消费者在线评论意愿,评论成本负向显著影响消费者在线评论意愿,而感知乐趣对其无显著影响。此外,感知易用性对消费者在线评论意愿无显著影响,但其对感知有用性呈显著影响。文章深入探讨消费者发表在线评论背后的动因,解决消费者在线发表评论意愿低等客观问题,对于互联网经济的长期发展具有非常重要的现实意义。      

略论社会资本视野下中国贫富差距拉大问题

以社会资本的网络特征为视角,从社会关系网络、体制对社会资源配置的影响等方面对当前我国社会贫富阶层社会资本的现状及其成因进行分析,可见,由于弱关系网络资源严重不足、现有管理制度和法律法规不健全以及民间组织缺乏等原因,弱势群体在社会资本方面处于劣势,贫富差距不断拉大。对此可考虑采取优化社会结构,尽力扩大社会中间阶层的规模;充分利用各种社会机构的作用;营造良好的制度环境等措施,以推动贫富差距逐步缩小,实现社会的真正和谐。     

读《马氏文通读本》札记

《马氏文通读本》是到目前为止最好的《马氏文通》版本之一,它已经成为"《马氏文通》研究"的经典之作。它的注释,评论者曾给予了很高的评价,但可商之处亦在,有观点主观并带臆断成分者,有证据不甚可靠而批评者,有解说不合原文旨意者,有分析不合原书体例者,有标点不当从而引起歧见者,因而需要加以讨论和澄清。     

基于在线评论的区域需求偏好识别方法

用户需求存在着区域差异，识别区域需求偏好是企业区域化经营策略的决策基础。为此，本文提出了一种基于在线评论的区域需求偏好识别框架。首先，从在线评论中提取产品特征，并判定产品特征的情感极性；然后，基于特征情感计算客户的产品满意度；最后，利用假设检验的方法识别特征情感极性和产品满意度的区域差异。为了验证框架的有效性，本文利用汽车之家网站上的汽车产品评论数据进行分析。实验结果表明，油耗、空间、外观和内饰等特征的情感极性以及产品满意度受区域因素的影响十分显著。研究结果建立起产品特征情感极性和产品满意度与区域特征的关联联系，为企业的区域化产品设计与营销策略提供理论支撑。     

A systematic review of psychosocial interventions for suicidal adolescents

Suicide is a leading cause of death for young people and rates of serious suicidal thoughts are even higher. Due to these high rates and potential harm to youth, effective interventions are necessary. The purpose of this systematic review was to determine the impact of interventions designed for suicidal adolescents. Both quasi-experimental and experimental designs in the published and unpublished literature were included, and a total of 17 studies were located. According to meta-analysis, intervention group participants were slightly less likely to have suicidal and self-harm events than control group participants. However, when studies assessed outcome at a later period than immediately after intervention, experimental group participants were slightly more likely to have suicidal and self-harm events than control group participants. For studies that measured suicidal ideation at posttest, intervention group participants were slightly less likely to report suicidal ideation than control group participants, both at posttest and at follow-up. These contradictory findings are explored and discussed.

国际政治经济学研究方法探析

国际政治经济学应综合运用西方经济学和马克思主义政治经济学的研究方法,将国内和国际政治因素纳入国际经济关系的研究。从总体上看,方法论的个人主义与整体主义相结合,是国际政治经济学研究方法所具有的基本特征。     

马克思"世界历史"理论的系统分析

马克思的“世界历史”理论把整个世界看作一个系统。马克思对人类社会发展规律的分析和研究体现了系统论的思想。作者运用系统分析的方法，对马克思的“世界历史”理论进行了初步的解读，认为马克思的“世界历史”理论具有系统的整体性、相关性和动态性特征。系统要素之间的冲突集中表现为东西方文明发展的不平衡性，这种不平衡性推动了世界历史的发展和进步。     

Reflections on rational choice—The existence of systematic irrationality

The behavioral challenge to the rational choice paradigm is oriented toward individual decision-making. Behavioral irrationality does not mean chaos. Most irrational behavior involves the exercise of reasoning. In reality, decision makers do not behave with full knowledge and/or optimal computational power in pursuit of maximizing expected utility. Besides reviewing critiques to the rationality paradigm for judgments and preferences and exploring the impact of culture on people's economic behavior, this paper is the first to call the attention of researchers to the phenomenon of systemic irrationality. Irrationality may exist at the aggregate or societal level, a conclusion based on the observation that large segments of the population are incapable of making decisions in accord with traditional rationality—groups such as those who have a psychiatric disorder, those who are taking medications, those with limited intelligence, those from the lower social classes, children and adolescents, and the elderly. Even those who are not included in the aforementioned groups, but who take medications for medical conditions may have their decision-making impaired to some extent. Therefore, it is argued that rationality in economic decision-making may be the exception rather than the norm.
