Buying a Dream: Alternative Models of Demand for Lotto

Existing lotto demand models utilize effective price, computed as the face value of a ticket minus the expected value of prize money per ticket, as their primary explanatory variable. By contrast, this article proposes a key role for consumption benefit or "fun" in the demand for gambling in general and lotto demand in particular. It develops an alternative model of lotto demand that focuses on the maximum possible prize. When this is tested against the traditional model using data from the U.K. National Lottery, we find that jackpot considerations exert an influence over and above that of variations in effective price.     

Rhetoric and Reality of Economic Self-sufficiency Among Rural,Low-Income Mothers: A Longitudinal Study

This study examined the contributions of maternal labor force participation and marital status on economic self-sufficiency over time for rural mothers. Data were from 174 rural families participating in three waves of data collection in Rural Families Speak. χ ² and multiple logistic regression were utilized. Results revealed only one-third of mothers moved toward economic self-sufficiency over three years. Maternal education, employment status, and weekly work hours were associated with improved economic well-being. Compared to single-parent families, unmarried-couple and married-couple families had increased odds of improving economically. In an analysis of all mothers with partners, married or unmarried, martial status was not significant in economic improvement. Findings suggest the role of marriage in welfare reform for rural families should be reconsidered.

Grievances do matter in mobilization

This article proposes that by studying grievances as not only materially but also ideationally constituted claims, scholars can gain analytical leverage on puzzles of social movement emergence and development. This meaning-laden approach to grievances recognizes that the ideas with which some claims are imbued might be more conducive to motivating political resistance than others. The approach is inherently grounded in context—scholars begin by understanding the meanings that grievances take on in particular times and places. But it is also potentially generalizable; as scholars uncover the ways in which apparently different grievances may index similar ideas across time and place, those grievances can be categorized similarly and their potential relationship to social mobilization explored. Drawing on evidence from the 2000 Bolivian water wars, the article proposes that market driven threats to subsistence resources offer one such potential categorization.     

Some chance for consensus: voting methods for which consensus is an equilibrium

We introduce the following basic voting method: voters submit both a “consensus” and a “fall-back” ballot. If all “consensus” ballots name the same option, it wins; otherwise, a randomly drawn “fall-back” ballot decides. If there is one potential consensus option that everyone prefers to the benchmark lottery which picks the favorite of a randomly drawn voter, then naming that option on all “consensus” ballots builds a very strong form of correlated equilibrium. Unlike common consensus procedures, ours is not biased toward the status quo and removes incentives to block consensus. Variants of the method allow for large groups, partial consensus, and choosing from several potential consensus options.     

Drinking Game Participation Among Undergraduate Students Attending National Alcohol Screening Day

Abstract

Objectives, Participants, Methods: Drinking game participation has increased in popularity among college students and is associated with increased alcohol consumption and alcohol-related problems. The current study investigated drinking game participation among 133 undergraduates attending National Alcohol Screening Day (NASD) in April of 2007. Results: A large percentage of the sample reported lifetime (77%) and recent (52%) drinking game participation. Males were more likely to report recent participation and reported higher levels of consumption while playing drinking games. Drinking game participants were more likely to experience a range of alcohol-related problems, and the relationship between drinking game participation and alcohol-related problems was mediated by weekly alcohol consumption. Conclusions: These results suggest that drinking game participation is a risk factor for elevated levels of alcohol consumption and alcohol-related problems. Programs should be developed to educate students about the risks of drinking game participation, and prevention programs like NASD should address drinking games.     

Bayesian hierarchical regression models for detecting QTLs in plant experiments

Quantitative trait loci (QTL) mapping is a growing field in statistical genetics. In plants, QTL detection experiments often feature replicates or clones within a specific genetic line. In this work, a Bayesian hierarchical regression model is applied to simulated QTL data and to a dataset from the Arabidopsis thaliana plants for locating the QTL mapping associated with cotyledon opening. A conditional model search strategy based on Bayesian model averaging is utilized to reduce the computational burden.     

Decisions concerning the allocation of scarce medical resources

This paper aimed to determine the criteria participants use to make decisions about scarce medical resources (allocation to use a kidney machine). It varied information about patients on 4 factors (sex, smoking, employment status, community service). It also set out to see if decisions made in groups differed from aggregated decisions of those made alone. In the first study, participants completed a simple questionnaire requiring them to rank-order sixteen hypothetical patients. In the second study, a group discussion (in groups of three participants) preceded the group putting an agreed rating on the identical questionnaire. Participants favoured patients who were employed, non-smokers and participated in community service. This suggests that participants adopted a utilitarian moral ideology. Participants' smoking habits interacted with the hypothetical patients' smoking habits, indicating in-group favouritism. In the second study it was found that when the decision was made in a group of three it amplifies the decision made by an individual. In this sense there was clear evidence of group polarization.
