Informed by the Pathways Model, the current study utilized latent class analysis (LCA) to empirically derive subtypes of gamblers based on measures of impulsivity, anxiety, depression, drug use and alcohol dependence. The sample in this study (N = 566) was comprised of young adult gamblers (18–22 years of age) who participated in the Manitoba Longitudinal Survey of Young Adults (MLSYA). Multinomial regression was utilized to examine how demographic variables and participant scores on the Problem Gambling Severity Index (PGSI) predicted membership in gambler classes from the LCA. Results of the LCA revealed three classes of gamblers: emotionally vulnerable, non-problem and impulsive. Multinomial regression showed that older age (i.e. 20–22 years of age), lower income (< $20,000 per year), living independently and PGSI scores were associated with increased odds of being classified as an impulsive gambler. Identifying as European, living independently and PGSI scores were associated with increased odds of being grouped in the emotionally vulnerable class of gambler. These results suggest that young adult gamblers are not a homogeneous group but instead are best understood as falling into different subtypes based on shared characteristics outlined in the Pathways Model.  相似文献

We assess competing explanations of irrational behavior in the Monty Hall problem by creating new variants of the problem. Some variants employ a feature that automates the merging of probabilities, thus rendering transparent the probabilistic advantage of the rational choice. That feature also enables systematic variation in informational asymmetry, and in ordering of actions. Data from 77 subjects, each of whom makes 30 binary decisions, indicate that automated merging raises the fraction of rational choices from around 40% to over 80%. Other features examined have much less impact, indicating the importance of a Bayesian updating failure. (JEL C91, D02, D81, D83)  相似文献

During the past decade, scholars continued to focus on how larger economic trends impacted families across the income spectrum. From income and wealth inequality to economic insecurity, the gaps between the haves and the have nots remained, and some widened during this period. The authors' comprehensive review found the following three major takeaways: first, the biggest economic divides run through families with children; second, low-income families face concentrated disadvantage marked by insecurity and precarity; and third, inequality and insecurity shaped the “dynamism” of family life, including how families respond culturally and emotionally to economic changes, and how these responses unfold over time. They examine active areas of research, including parenting trends and the transition to adulthood. They also document a new scholarly emphasis on uncertainty and instability along with the forces that exacerbate or mitigate them, such as job quality, economic volatility, wealth, and incarceration. Research during the past decade focused on the experience and consequences of dynamism, reflecting not only the reality that families evolve but also that they face continual change in their economic, social, and political contexts. The authors highlight research investigating how families “do dynamism,” work that looks over time or offers in-depth examinations of how families adapt to and cope with dynamism every day. This research reveals that inequality and insecurity are not only matters of levels and gaps but also ongoing matters of meaning-making, identity, and feeling. The authors conclude by highlighting some strengths and weaknesses of these research streams and pointing out new avenues for future scholarship.  相似文献

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.
