Binge eating is characteristic of eating and weight-related disorders such as binge eating disorder, bulimia nervosa, and obesity. In light of data suggest impulsivity is associated with overeating specifically in restrained eaters, this study sought to elucidate the exact nature of the associations between these variables, hypothesizing that the relationship between impulsivity and binge eatin...

Stice's dual pathway model of dietary restraint and negative affect was examined in both adolescent girls and boys. Self-report measures assessing body dissatisfaction, dietary restraint, negative affect and bulimic behavior were administered to 267 girls and 199 boys aged between 12 and 16 years. The findings for the girls were consistent with Stice's model, in that they indicated that both di...

OBJECTIVE Previous research has shown that women, restrained eaters, and overweight/obese individuals have a tendency to underreport their weight. This study investigated gender, dietary restraint, and BMI to determine which is the best predictor of errors in self-reported weight. METHOD A total of 241 college students completed questionnaires pertaining to height and weight and then were wei...

Under what conditions does, or should, a collective of rational individuals support the imposition of a binding constraint on their own collective action? Our innovation is to allow citizen-taxpayers in a standard political economy model to be risk-averse and uncertain about the future average cost of the collective good, their own future income or wealth, and the future distribution of the tax...

Multi-antibiotic-resistant Gram-negative pathogens are becoming more prevalent and an association exists between chromosomally conferred fluoroquinolone resistance and the presence of plasmid-borne resistances, such as extended spectrum beta-lactamases. This link is not wholly explained by strain spread or the presence of fluoroquinolone-modifying enzymes. Plasmid-encoded toxin-antitoxin addict...

T HE controversial history of allozyme studies: Alternative heritable forms of enzymes, differing in charge or shape, have been known since the 1940s; these may be alleles of one gene (allozymes) or products of distinct but related genes (isozymes). LEWONTIN and HUBBY (1966), finding an unexpected bonanza of allozyme variation in Drosophila, re-cast the existing debate about the evolutionary me...

OBJECTIVE To reconcile empirical inconsistencies in the relationship between emotionally-negative families and daughters' abnormal eating, we hypothesized a critical moderating variable: daughters' vulnerability to emotion contagion. METHOD A nonclinical sample of undergraduate females (N = 92) was recruited via an advertisement and completed self-report measures validated for assessing: fami...

In this paper we model a decision maker who must exert costly effort to complete a single task by a fixed deadline. Effort costs evolve stochastically in continuous time. The decision maker will then optimally wait to exert effort until costs are less than a given threshold, the solution to an optimal stopping time problem. We derive the solution to this model for three cases: (1) time consiste...
