We present a novel experiment demonstrating strategies selfish individuals utilize to avoid social pressure to be altruistic. Subjects participate in a trust game, after which they have an opportunity to state their beliefs about their opponent's actions. Subsequently, subjects participate in a task designed to “reveal” their true beliefs. Subjects who initially made selfish choices falsely state their beliefs about their opponent's kindness. Their “revealed” beliefs were significantly more accurate, which exposed subjects' knowledge that their selfishness was unjustifiable by their opponent's behavior. The initial false statements complied with social norms, suggesting subjects' attempts to project a more favorable social image. (JEL C9, D03, D83) 相似文献

ABSTRACT Online scambaiting problematises the identity of the 419 scammer whose virtual labours connect significantly to the digital dimensions of Afropolitanism. When examined through the photographic practices demanded of 419 scammers in several Internet communities, scambaiting, a form of Internet vigilantism that is targeted at online scammers to avert scam, produces epistemic violence which evacuates the black male body of human dignity. Although scambaiting is potentially an ethical project, it embeds a system of oppression that generates Afropolitan masculinities, caricatured performances of the bodies of 419 scammers exhibited online as objects of shame. As a philosophical and aesthetic response to translocality and mobility, Afropolitanism stresses the cultural experiences and agency of ordinary Africans who assert a global sense of awareness. As both the Afropolitan subject and the 419 scammer are entangled in the assertion of agency, the globalism of both is shown to converge at the intersection of the digital. Building on Lisa Nakamura's essay on dogshaming, I argue that the sexual exploitation of black bodies on scambaiting websites gestures at technology's complicity in interpellating digital subjects and circulating social injustices. Unlike Nakamura, I foreground the performative aspects of scambaiting and connect these to Afropolitanism's intrinsic digitality. 相似文献

Social media is now used as a forecasting tool by a variety of firms and agencies. But how useful are such data in forecasting outcomes? Can social media add any information to that produced by a prediction/betting market? We source 13.8 million posts from Twitter, and combine them with contemporaneous Betfair betting prices, to forecast the outcomes of English Premier League soccer matches as they unfold. Using a microblogging dictionary to analyze the content of Tweets, we find that the aggregate tone of Tweets contains significant information not in betting prices, particularly in the immediate aftermath of goals and red cards.

This national qualitative study explores recruitment and retention strategies within state child welfare agencies and the perceived effectiveness of these strategies. The study includes a national review of 50 state child welfare websites, and qualitative interviews with 18 individuals in 13 states. The findings highlight agencies' identification and investment of similar types of recruitment and retention efforts; yet agencies still grapple with elevated turnover rates despite continued efforts. This article comprehensively explored national utilized and underutilized strategies that have been employed to help alleviate child welfare recruitment and retention challenges. Further, mechanisms for overcoming and promoting innovation to understand the effectiveness of child welfare recruitment and retention strategies are addressed. 相似文献

AbstractFor authors, publishers, and researchers, the information roadmap charts and utilizes evolving technology. “Infomediary” is a new name for an old role, describing participation in both traditional and emerging ways to deliver information and publications. This article briefly defines the role of the infomediary and the types of services provided by companies such as Ingenta, ISI (Institute for Scientific Information), and Gale. The best infomediaries will provide rational order to the growing and changing base aggregation of published material as it moves from researcher to author to publisher to library and back to researcher, particularly as that material evolves from print to electronic form. 相似文献

This paper explores the cross-national challenges of integrating evidence-based interventions into existing services for high-resource-using children and youth. Using several North American model programme exemplars that have demonstrated efficacy, the paper explores multiple challenges confronting policy-makers, evaluation researchers and practitioners who seek to enhance outcomes for troubled children and youth and improve overall service effectiveness. The paper concludes with practical implications for youth and family professionals, researchers, service agencies and policy–makers, with particular emphasis on possibilities for cross-national collaboration. 相似文献

Public risk perceptions and demand for safer food are important factors shaping agricultural production practices in the United States. Despite documented food safety concerns, little attempt has been made to elicit consumers' subjective risk judgments for a range of food safety hazards or to identify factors most predictive of perceived food safety risks. In this study, over 700 conventional and organic fresh produce buyers in the Boston area were surveyed for their perceived food safety risks. Survey results showed that consumers perceived relatively high risks associated with the consumption and production of conventionally grown produce compared with other public health hazards. For example, conventional and organic food buyers estimated the median annual fatality rate due to pesticide residues on conventionally grown food to be about 50 per million and 200 per million, respectively, which is similar in magnitude to the annual mortality risk from motor vehicle accidents in the United States. Over 90% of survey respondents also perceived a reduction in pesticide residue risk associated with substituting organically grown produce for conventionally grown produce, and nearly 50% perceived a risk reduction due to natural toxins and microbial pathogens. Multiple regression analyses indicate that only a few factors are consistently predictive of higher risk perceptions, including feelings of distrust toward regulatory agencies and the safety of the food supply. A variety of factors were found to be significant predictors of specific categories of food hazards, suggesting that consumers may view food safety risks as dissimilar from one another. Based on study findings, it is recommended that future agricultural policies and risk communication efforts utilize a comparative risk approach that targets a range of food safety hazards. 相似文献
