大学生诚信水平与诚信态度分析

对大学生诚信水平和诚信态度的研究结果表明：大学生总体诚信水平较好,大学生的诚信水平在学科、性别、年级、生源地、是否独生子女、父母文化程度、月支出额等特征上存在差异,大学生的诚信水平与其对社会和谐的认识和信心呈正相关。     

博客共享性的传播心理学分析

近年来个性化网络出版形式--博客蓬勃发展。博客体现出来一种共享性与公共性的传播精神。博客使用者在网上的公开写作,表现出资讯共享、思想共享与情感共享的精神;而博客阅读者发表的评论也体现出提供更多资源与情感共鸣的共享性。现从传播心理学的角度,以利他性行为理论工具,对博客的共享性产生原因、过程进行分析。     

政府行为文明内涵的新发展：行政权力良性扩张

政府行为文明的本质是政府的现代化，政府现代化的本质则是政府发展和行政发展。作为一种抽象的政府行为，行政权力扩张有良性扩张和恶性扩张之分，分别体现着行政权力扩张的必然性与人为性。提出行政权力良性扩张是社会发展的需要，本质是政府发展和行政发展，其结果是政府行政能力的提升、行政能量的增强。无论是从良性扩张产生的原因还是实现的结果来看，行政权力良性扩张都体现着政府行为文明本质要求，是对政府行为文明内涵的发展。     

基于博弈分析的农村信用社产权改革路径选择

随着我国农村信用社改革的步步深化,新型产权组织模式与运行机制的构建已经走到了攻坚阶段。文章在归纳分析农村信用社改革与发展背景及基本现状的基础上,围绕政府与农村信用社双方的益损值,对政府推行农村信用社合作制规范进行了博弈分析,由最终的纳什均衡分析结果,得出了在现有农村信用社基础上搞统一的合作制规范不切实际,农村信用社改革必须走“多元化”产权组织模式道路的结论,并就新时期如何进一步发展与完善农村信用社“多元化”产权组织模式提出了几点政策性建议。     

Risk Factors for Chronic Posttraumatic Stress Symptoms and Behavior Problems in Children and Adolescents Following a Home Fire

Based on a model of (Posttraumatic Stress Disorder) PTSD by Green, Wilson and Lindy (1986), fifty-six children ages 6 to 17 years were interviewed at five months (T1) and 9 months (T2) after a fire in their homes. Outcome variables were PTSD and behavior problems. Major correlates of the outcome variables, include guilt at T1, worry about other family members at T2, and lack of satisfaction with family support at both times, as well as the attribution that another child did it. The stressor variable, present at the fire, became significant only at T2. The greatest variance in the PTSD scores occurred at T2 suggesting delayed onset or delayed reporting by children. Children may process traumatic events in a different cognitive fashion and in a different time frame than adults. Implications of these results are considered within the context of social work and nursing.     

The Dark Side of Information and Market Efficiency in E‐Markets*

Price dispersion reflects the differences in prices for identical products. While in physical markets such dispersion is prevalent due to high search costs, many researchers argue that search costs and price dispersion will be much lower in electronic markets (e‐markets). Empirical evidence does not support this contention, and researchers have studied search costs, market factors, and service‐quality factors to explain this dispersion. Previous research has largely assumed that more information is better. By ignoring the dark side of information, we argue that only a partial understanding of price dispersion is possible. In this article, information overload and equivocality are studied as two dark attributes of information that lead sellers to different pricing decisions in e‐markets. Hypotheses relating these attributes to price dispersion are supported through analysis of 161 product markets. This work opens up new avenues in the study of e‐markets and discusses the implications of these findings for research and practice on consumer and seller decisions.     

Mentoring At-Risk Latino Children and Their Parents: Impact on Social Skills and Problem Behaviors

The Family Mentoring Project, which provided approximately one year of mentoring for at-risk 10-year old Latino children and their parents, aimed to provide not only service but empirical evaluation of the program's impact. This University-community partnership offered individual mentoring, a group educational component for children and parents, and group social/recreational activities. A pre- and post-test analysis of 11 non-mentored and 20 mentored youth revealed positive gains on social skills for mentored children as reflected in self-ratings and mothers' ratings on the Social Skills Rating Scale (SSRS). Also based on the SSRS, mothers reported decreases in three problem behaviors for mentored children. In addition, by post-testing, the mentored children and their mothers compared very favorably with the SSRS standardized samples on both skills and problem behaviors. The findings suggest that bicultural competence may be fostered by programs that provide consistent and long-term mentoring, involve the children's families, include group educational components, and bring families and mentors together for social/recreational events.     

Gender differences in entrepreneurial intentions: A TPB multi-group analysis at factor and indicator level

Previous research suggests that diverse factors predict gender differences in entrepreneurial intent. Our paper integrates and expands on previous findings using the Theory of Planned Behavior (TPB), including the deeper-level measurement model, allowing for a better understanding of the origin of differences. The results of a survey with business students indicate that the effect of gender on entrepreneurial intentions is mediated via personal attitudes and perceived behavioral control but not social norms. More precisely, vis-à-vis their male counterparts, women are more driven toward entrepreneurship by motives to ‘get organized’ (balance) that are less dominant in predicting personal attitude. Moreover, female students are somewhat less driven toward entrepreneurship by beliefs of internal control that are more dominant in predicting perceived control. Finally, while female students are also more motivated to comply with normative role models, this did not influence their entrepreneurial intentions over and above perceived behavioral control and personal attitude. We discuss both practical and theoretical implications of our findings.     

Optimal Temporal Customer Purchasing Decisions Under Trade‐In Programs with Up‐Front Fees

To entice customers to purchase both current and new generation products over time, many firms offer different trade‐in programs including programs that require customers to pay an up‐front fee. To examine the effectiveness of the trade‐in programs, we develop a two‐period model in which a firm sells the first generation product in the first period and the second generation product in the second period; however, the firm offers a trade‐in program that customers can participate in when purchasing the first generation product in the first period. To participate, each customer has to pay a nonrefundable fee in the first period so that she has the option to trade‐in her first generation product and receive a prespecified trade‐in value to be used for the purchase of the second generation product in the second period. To capture market heterogeneity and market uncertainty, we examine the case when the valuation of the first generation product varies among customers and the valuation of the second generation product is uncertain a priori. By analyzing a two‐period game, we determine the optimal purchasing behavior of each rational customer, and we show that the firm is always better off by offering its own trade‐in programs. Also, our numerical analysis reveals that trade‐in programs can benefit the firm significantly especially when (i) the residual value of the first generation product is high; (ii) the expected incremental value of the second generation product is high; or (iii) the valuation of the second generation product is highly uncertain.     

The Importance of Social Embeddedness: Churn Models at Mobile Providers

This article argues the importance of social embeddedness at mobile providers by examining the effects of customers’ network topological properties on churn probability—the probability of a customer switching from one telecommunication provider to another. This article uses data from regional snowball sampling—the only practically feasible network sampling method—to identify groups with significantly different churn ratios for customers with different network topological properties. Clear evidence indicates that individual network characteristics (node‐level metrics) have considerable impact on churn probabilities. The inclusion of network‐related measures in the churn model allows a longer‐term projection of churners and improves the predictive power of the model. With no possibility to carry out repeated sampling, sample stability was checked through simulation results. On the one hand, this article highlights the importance and effectiveness of the provider's tailored marketing campaigns by showing that customers targeted by direct marketing campaigns are less threatened by churn than nontargeted customers. On the other, this article shows that social embeddedness blocks the impact of the very same marketing efforts. This article forwards the idea that social embeddedness, also prevalent in vendor switching, can be extended to understanding the development of professional societies threatened by membership churn.
