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.     

Influences Between Online‐Exclusive,Conjoint and Offline‐Exclusive Friendship Networks: The Moderating Role of Shyness

Prior research has indicated that shy adolescents are more motivated to form friendships online than to form friendships offline. Little is known about whether having friendships found exclusively online may impact self‐esteem and forming offline friendships for these adolescents. This study therefore aimed to provide insight into the moderating role of shyness in the longitudinal interplay between friendships in online and offline contexts in early adolescence. Adolescents and their friends (193 girls, 196 boys; M_age = 13.29) were followed with three consecutive measurements with intervals of eight months. Results showed that particularly for shy adolescents, having friends exclusively online predicted increases in self‐esteem. Self‐esteem, in turn, was found to predict forming more friendships found both offline and online and forming more friendships found exclusively offline. Thus, findings supported the social compensation perspective that shy adolescents may benefit from having friends exclusively online, as these friendships may increase self‐esteem, thereby facilitating the formation of friendships found partially and completely offline.

Online disinhibition: heightened potential for professional conduct issues among clergy in the Church of England?

This article identifies the potential of online social networking encounters to heighten the risk of professional conduct issues among clergy in the Church of England. It first considers the difficulties in establishing what constitutes inappropriate conduct for clergy working in complex twenty-first century contexts, and then goes on to suggest that the online disinhibition effect might form a significant factor in problematic online encounters, drawing on the work of psychologist John Suler, and other previous research. It then considers the question of how online identity might mesh or jar with embodied identity for clergy, and concludes that awareness of the online disinhibition effect coupled with conscious integration of online involvements into their broader support networks, rather than compartmentalising them, form useful ways for clergy to undermine toxic online disinhibition.     

Two selves and online forums in China

Chinese society is characterized by emerging fragmentation and by the coexistence of traditional and Western values, goals and norms. In this multifaceted environment bi‐cultural selves, which encompass social and individual orientations, may emerge. The aim of this paper is to explore if features of bi‐cultural selves concerning interactions, emotions, and values are reflected in online public discussions in China. In order to address this question, we explored two of the most popular bulletin board systems (BBSs): Tian Ya and Feng Huang Forums. BBSs attract almost one third of Internet users in China and provide these users with a forum to carry out public dialogue; BBSs are thus an ideal place to study how the self is socially shaped in public communication. A sample of 6109 messages was subjected to quantitative content analysis. Results show that twofold self‐construal, corresponding to the individual‐ and social‐oriented self, are (also) detected in BBSs forum content: direct and polemic content coexist with conciliatory content; ego‐focused and other‐focused emotions are almost equally as frequent as one another; and traditional values are evoked together with the quest for truth and individual rights. Moreover, three typologies of Internet users (proactive, ambivalent, and follower), which were identified on the basis of the quality of their online interactions, show different patterns of emotions and values. We may thus conclude that alternative ways of constructing self‐other and self‐society relationships currently coexist in China and that these alternative views confront each other on BBS forums.
