刷屏的原理：在线内容的病毒式分享机制

通过社交网络发布优质在线内容以引发消费者的主动分享从而使该内容像病毒一样传播开来的营销方式被称为病毒式营销。在线内容的病毒式分享机制主要包括内容特征、心理动机、情绪反应、情境因素以及个体特征这五个方面, 可以为品牌和自媒体有效提高在线内容的分享转发率提供系统的理论指导。未来研究需要进一步探索某些具体情绪的作用机制, 识别出更多本土背景下的情境因素, 关注病毒式营销的效果评估和心理行为后果, 并采用更加多样化的研究方法。     

默认选项助推老年人意外伤害险在线购买

老年人意外伤害保险作为应对人口老龄化带来的意外风险的措施之一,能够有效缓解老年人意外伤害给其和家庭造成的经济负担。然而该险种购买不足的现状有可能影响其持续运营。本研究试图通过四个子研究探讨默认选项的助推方式是否能够促进老年人意外伤害险在线购买额。研究1通过实际销售数据分析,研究2~4通过实验发现:把默认选项设置在最高份数上能够有效地促进保险的购买份额。研究表明应用行为科学的发现可以有效促进公共政策的实施。     

网络募捐中求助者的面部表情对捐助意愿的影响：有中介的调节模型

基于框架效应和共情–助人行为假说,以82名大学生为被试,通过实验探讨了网络募捐中求助者的面部表情对捐助意愿的影响,并考察了目标框架的调节作用以及共情的中介作用。结果表明：目标框架调节了求助者的面部表情对捐助者的共情和捐助意愿的影响。在积极框架下,消极面部表情对捐助者的共情和捐助意愿的积极影响显著高于积极面部表情;而在消极框架下,两种面部表情对捐助者的共情和捐助意愿的影响均无显著差异。研究还发现了有中介的调节作用模型,共情在求助者的面部表情对捐助意愿的影响中发挥中介作用,而目标框架是有中介的调节变量。     

面部表情与捐赠者–受益者关系对网络慈善众筹捐赠行为的影响

网络慈善众筹是从在线社区获得财力捐助的行为。本研究通过3个实验,考察在线社交平台上受益者面部表情与捐赠者–受益者关系对慈善众筹捐赠行为的影响。结果发现,快乐的面部表情对捐赠金额和分享意愿的影响总体上比悲伤更大;捐赠者–受益者共有的熟人关系比陌生人关系对捐赠金额与分享意愿的影响更大;面部表情与捐赠者–受益者关系对慈善众筹的捐赠金额存在交互作用,但对分享意愿没有显著性影响。结果表明,在线社交平台的慈善众筹捐赠行为更偏好有快乐面部表情的受益者,并且更多地受到间接的、社会交换预期微弱的熟人共有关系的影响。     

Feedback and its effectiveness in a computer-aided personalized system of instruction course

In a computer-managed version of Keller's personalized system of instruction, students received frequent feedback from more advanced students within the course. Overall accuracy of student-provided feedback was 87%, and students complied with 61% of the feedback.     

Using electronic discussion boards to teach responsible conduct of research

This study presents the results of a survey of student satisfaction with electronic discussion boards in a course on the responsible conduct of research (RCR). On a 1–5 scale, the respondents stated that the use of the electronic discussion board was an effective teaching tool (4.71), that it enabled them to get feedback from their peers (4.43), that it helped promote discussion and debate (4.36), that it helped them learn how to analyze ethical dilemmas in research (4.36), and that they would consider using an electronic discussion board, if they ever taught a course themselves (4.76). In their written comments, the respondents indicated that electronic discussion boards are a convenient way of promoting debate and in-depth discussion. These results suggest, but do not prove, that discussion boards can promote debate and discussion in courses on research ethics. Instructors who teach RCR should consider using electronic discussion boards in regular or online courses, and they should consider studying the effectiveness of electronic discussion boards in research ethics education. Although electronic discussion boards cannot replace the face-to-face interaction that occurs in a classroom setting, they may provide a useful medium for the exchange of ideas and opinions online.     

PHILOSOPHICAL THEORIES OF PRIVACY: IMPLICATIONS FOR AN ADEQUATE ONLINE PRIVACY POLICY

Abstract: This essay critically examines some classic philosophical and legal theories of privacy, organized into four categories: the nonintrusion, seclusion, limitation, and control theories of privacy. Although each theory includes one or more important insights regarding the concept of privacy, I argue that each falls short of providing an adequate account of privacy. I then examine and defend a theory of privacy that incorporates elements of the classic theories into one unified theory: the Restricted Access/Limited Control (RALC) theory of privacy. Using an example involving data‐mining technology on the Internet, I show how RALC can help us to frame an online privacy policy that is sufficiently comprehensive in scope to address a wide range of privacy concerns that arise in connection with computers and information technology.     

Assessing students' use of optional online lecture reviews

Online practice quizzes can be used to supplement instruction in the classroom. Such quizzes can engage retrieval practice, thereby improving learning and retention. However, despite their potential benefits, recent work suggests that students typically underutilize online practice quizzes. This article reports an observational classroom study, in which students were provided optional online reviews throughout the semester. The reviews could be accessed in test format, in which students were given multiple-choice questions and provided correct answer feedback, or in read format in which students were given the same questions and were shown the correct answers. Students who used the test format performed better on exams than students who used the read format or did not use the reviews. Nevertheless, the massive majority of the online reviews (approximately 88%) were not completed, highlighting the tendency for students to underutilize optional online reviews.     

Cyber-bullying: An investigation of the psychological profile of university student participants

The present study investigated the psychological profile of 430 Greek university students who reported cyber-bullying/victimization experiences. Participants completed a self-report questionnaire, measuring cyber-bullying, cyber-victimization, Internet frequency and use, personality characteristics, and psychological symptoms. Results indicated that 58.4% of the sample had participated in a cyber-bullying incident assuming any role. Cyber bully/victims, the most common participant role, endorsed more psychological symptoms, more psychopathic traits, and were high sensation seekers, compared to the rest of the groups, whereas cyber-victims scored higher on empathy. Cyber-bullying was predicted by callous/unemotional and impulsive/irresponsible traits, depression, Internet use, as well as lack of social skills. The latter four variables also predicted cyber-victimization along with gender. Findings are discussed in terms of prevention and intervention strategies.
