Research has revealed that overall life satisfaction (LS) is negatively related to disordered eating. This study examined whether specific LS domains (e.g., family, friends, etc.) were more strongly associated with eating behaviors/weight perceptions (e.g., exercising to lose weight, using laxatives to lose weight, etc.) in 723 randomly selected college students analyzed separately by gender. Data were analyzed using logistic and multiple regression procedures. Results supported the hypotheses in the expected directions. College students’ weight perceptions had the strongest relationships with Satisfaction with Self and Satisfaction with Physical Appearance, and these relationships were stronger among females than males. Worrying about weight, self-described weight, and binge eating were significantly correlated with all LS domains (p < .05). Results suggest potential contributions of differentiating among the domains of LS in efforts to understand disordered eating among males and female college students. Implications for practice are discussed briefly.  相似文献

For the case of a one‐sample experiment with known variance σ2=1, it has been shown that at interim analysis the sample size (SS) may be increased by any arbitrary amount provided: (1) The conditional power (CP) at interim is ?50% and (2) there can be no decision to decrease the SS (stop the trial early). In this paper we verify this result for the case of a two‐sample experiment with proportional SS in the treatment groups and an arbitrary common variance. Numerous authors have presented the formula for the CP at interim for a two‐sample test with equal SS in the treatment groups and an arbitrary common variance, for both the one‐ and two‐sided hypothesis tests. In this paper we derive the corresponding formula for the case of unequal, but proportional SS in the treatment groups for both one‐sided superiority and two‐sided hypothesis tests. Finally, we present an SAS macro for doing this calculation and provide a worked out hypothetical example. In discussion we note that this type of trial design trades the ability to stop early (for lack of efficacy) for the elimination of the Type I error penalty. The loss of early stopping requires that such a design employs a data monitoring committee, blinding of the sponsor to the interim calculations, and pre‐planning of how much and under what conditions to increase the SS and that this all be formally written into an interim analysis plan before the start of the study.

There are a disproportionate number of professional women working through temporary agencies. We develop a theory wherein this gender skewness in temporary-agency employment results from the differences in perceptions of control at work between men and women working through large traditional organizations. Our theory suggests that if control is perceived to be less for women than for men in large organizations, then women will tend to populate other work arrangements, like temporary agencies, in order to enhance their control. Propositions are tested via a unique data set comparing the responses of employees from both a London temporary accountancy agency and a large London accountancy firm. Our results are consistent with a lack of control driving professional women from large firms to temporary agencies, and neither rely on preference differences nor familial obligations.  相似文献

The rational choice theory of crime and its cognate field of study, situational crime prevention, have exerted a considerable influence in criminal justice policy and criminology. This article argues that, while undeniably useful as a means of reducing property or acquisitive crime, rational choice‐inspired situational crime prevention initiatives are limited when it comes to offering protection against a growing number of so‐called ‘expressive crimes’. Developing this critique, the article will criticize the sociologically hollow narrative associated with rational choice theories of crime by drawing on recent research in social theory and consumer studies. It argues that the growing tendency among many young individuals to engage in certain forms of criminal decision‐making ‘strategies’ may simply be the by‐product of a series of subjectivities and emotions that reflect the material values and cultural logic associated with late modern consumerism.  相似文献

Stability definitions for describing human behavior under conflict when coalitions may form are generalized within the Graph Model for Conflict Resolution and algebraic formulations of these definitions are provided to allow computer implementation. The more general definitions of coalitional stabilities relax the assumption of transitive graphs capturing movements under the control of decision makers, either independently or cooperatively, and allow the convenient expansion to the case of coalitions of the four basic individual stabilities consisting of Nash stability, general metarationality, symmetric metarationality, and sequential stability. To permit the various coalitional stabilities to be efficiently calculated and conveniently encoded within a decision support system, algebraic expressions for the coalitional stabilities are provided in this research. Furthermore, a range of the theorems establish the mathematical credibility of employing the innovative algebraic approach to conflict resolution when coalitions are present. Finally, a conflict over the proposed exportation of bulk water from Lake Gisborne within the Canadian Province of Newfoundland and Labrador is modelled and analyzed to illustrate the practical application of the different coalitional stabilities and the strategic insights they provide.  相似文献

A self-contained FORTRAN subroutine is provided which computes factors for Wald-Wolfowitz type tolerance limits allowing arbitrary combinations of sample size n and degrees of freedom ν. The exact calculations from our program reveal inadequacies of two existing approximations, especially when ν ? n. Numerous applications where νn ? 1 are cited; two of these are discussed and illustrated.  相似文献

Gender, marital status, age, and race were considered in relation to the amount and assessment of social ties among 1,124 unmarried men and women aged 40 and over. When there were significant effects of marital status, widowed people tended to be advantaged in amount and supportiveness of their informal ties, although the influence of marital status was affected by age and race. Contrary to some literature, gender differences in social relationships favoring women were not consistently observed. The oldest never married may have the greatest potential needs for affective and instrumental support.  相似文献

‘Shylock is not Heartless’ uses poetry, film and the popular press to illustrate men's adherence to the traditional male tasks of protector and provider. Some men shift from protector and provider to the negative equivalent, controller and possessor, at the crisis point of separation. For others, separation provides the impetus for a journey inward toward self. The metaphor of the Iceberg and the Ocean has been found useful in helping some men observe the differences between them and their female partners.  相似文献
