Locus of control and other-regarding behavior: Experimental evidence from a large heterogeneous sample

This paper investigates the relationship between locus of control and other-regarding behavior in a large and heterogeneous sample of the French population. We relate locus of control with incentivized measures of other-regarding behavior in the dictator and ultimatum games. Participants with high internal locus of control offer comparatively less in situations with passive responders (dictator game) but tend to increase their offers when their counterparts have veto power (ultimatum game). Moreover, they appear better at anticipating responders’ behavior in the ultimatum game, which leads to offers with a higher probability of acceptance and higher expected payoff. Some results for the ultimatum game, however, are sensitive to model specification and sample composition. Our findings suggest that a high internal locus of control increases individuals’ ability to adapt to strategic and non-strategic settings.     

GENSI: A new graphical tool to collect ego-centered network data

This study (1) tested the effectiveness of a new survey tool to collect ego-centered network data and (2) assessed the impact of giving people feedback about their network on subsequent responses. The new tool, GENSI (Graphical Ego-centered Network Survey Interface), allows respondents to describe all network contacts at once via a graphical representation of their networks. In an online experiment, 434 American adults were randomly assigned to answer traditional network questions or GENSI and were randomly assigned to receive feedback about their network or not. The traditional questionnaire and GENSI took the same amount of time to complete, and measurements of racial composition of the network showed equivalent convergent validity in both survey tools. However, the new tool appears to solve what past researchers have considered to be a problem with online administration: exaggerated numbers of network connections. Moreover, respondents reported enjoying GENSI more than the traditional tool. Thus, using a graphical interface to collect ego-centered network data seems to be promising. However, telling respondents how their network compared to the average Americans reduced the convergent validity of measures administered after the feedback was provided, suggesting that such feedback should be avoided.     

A world without Down’s syndrome? Online resistance on Twitter: #worldwithoutdowns and #justaboutcoping

Presented by actress and comedian Sally Phillips, A World Without Down’s Syndrome has brought important ethical debates regarding prenatal screening into the public domain. By talking to people with Down’s syndrome, family members, and professionals, Sally has presented a nuanced and thorough examination of the type of world we are living in. Following the documentary, Twitter users have continued to engage with debates and have created a resilient platform for challenging public attitudes. This paper explores the ways in which Twitter hashtags have provided a space for such important and long overdue conversations. While it would not be possible to provide a full overview of the topical conversations that the two hashtags have provoked, I aim to focus on some of the most prominent topics. The following, then, will explore the potential of alternative narratives that resist, and disrupt, normative notions of the human using the hashtags #worldwithoutdowns and #justaboutcoping.     

Online public deliberation in China: evolution of interaction patterns and network homophily in the Tianya discussion forum

Internet discussion platforms in China provide a hugely interesting and relevant source for understanding dynamics of online discussions in a unique context. Adopting the theoretical lens of public deliberation, this paper investigates the evolution of patterns of similar-minded and different-minded interactions over time on a Chinese online discussion forum. We analyse the content and reply networks of 18,000+ messages on four highly debated topics on the Bulletin Board System (BBS) platform Tianya. Findings provide nuanced evidence to the phenomenon of increased network homophily over time, mitigated in discussions where the difference between opinion sides is smaller, and participants have positive opinions. Providing empirical foundation for testing and refining the tenets of public deliberation in the unique socio-cultural and institutional environment of China, this study lays ground for future investigation on independent variables for understanding dynamics of online discussions, and for studies comparing cases across different contexts.     

Online radio listening as ‘affective publics’? (Closeted) participation in the post-Umbrella Movement everyday

The porosity of the online media space blurs the boundary between the political, the popular and the social. While most media scholarship concentrates on the ‘DIY participation’ that the internet enables, it overlooks the fact that most of the users are just consumers of the array of political platforms. Employing Ranciere’s notion of the aesthetics of the everyday and using the case of online radio listening, the paper re-examines the politics of participatory practices in the politicized everyday, as the audience traverses fan practices and quotidian virtual activism. This paper focuses on elderly and female listener communities, to discuss how the porous social mediascape may foster a ‘participation of the sensible’, where ‘the ordinary’ engages in online radio listening as subversive act against the government, but also calculated political AND social strategy against the harshening political reality and social division. The case of Hong Kong would also hope to articulate the nuanced interplay between media participation and the politically divided juncture.     

Conflict of interest reporting in biomedical journals published in China

This study aimed to investigate the current status and policy of Conflict of interest (COI) reporting in biomedical journals in China. Thirty Chinese-language medical journals and 37 English-language biomedical journals indexed by Journal Citation Reports categories were included into this study. These 67 journals were all published in China. All articles published in the most recent two issues were checked for identifying the disclosure statement in the text or not. Twenty-one of 30 (70%) Chinese-language journals required a disclosure of author’s potential COI. No journals require editors or referees to disclose the conflicts of interest to the readers. In total, 1,212 publications in Chinese-language were evaluated. Only two journals reported COI in their publications. For the 37 English-language journals, 32 (86.5%) required author’s potential COI disclosure, and four of them required only research articles or original articles to disclose COI. A total of 1,170 publications were evaluated. Among them, 50% editorials, 79.3% review articles, and 73.6% original articles reported presence or absence of COI. In our studied journals, the percentage of the policies requiring author COI disclosure is still low. Biomedical journals published in China should enforce COI disclosure policies to authors, editors, and referees.

Managing Risks in Multiple Online Auctions: An Options Approach*

The scenario of established business sellers utilizing online auction markets to reach consumers and sell new products is becoming increasingly common. We propose a class of risk management tools, loosely based on the concept of financial options that can be employed by such sellers. While conceptually similar to options in financial markets, we empirically demonstrate that option instruments within auction markets cannot be developed employing similar methodologies, because the fundamental tenets of extant option pricing models do not hold within online auction markets. We provide a framework to analyze the value proposition of options to potential sellers, option‐holder behavior implications on auction processes, and seller strategies to write and price options that maximize potential revenues. We then develop an approach that enables a seller to assess the demand for options under different option price and volume scenarios. We compare option prices derived from our approach with those derived from the Black‐Scholes model ( Black & Scholes, 1973 ) and discuss the implications of the price differences. Experiments based on actual auction data suggest that options can provide significant benefits under a variety of option‐holder behavioral patterns.     

MSW Student Experiences in Online vs. Face-to-Face Teaching Formats?

Institutions of higher education have embraced online formats as a new form of teaching in order to reach more students. Like other disciplines, social work pedagogy has embraced the use of online technology in higher education. As a professional and ethical responsibility, it is imperative that social work online courses are of high quality and that they meet the stated objectives. The study presented here describes students' perceptions and experiences in online and in-classroom sections in the Theories and Practice with Communities and Agencies course at a large public university in Southeastern USA. A survey was administered to the students at the end of the semester. Qualitative themes show that method of instruction as it related to course content, comfort with the level of instruction, and role of instructor in online courses affected students' perceptions of both the course and method of instruction. Discussions are directed toward improving online instruction in social work education.
