Neighbors C Lostutter TW Larimer ME Takushi RY 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》2002,18(4):339-360
The present research describes the proposal and validation of three gambling outcome measures, the Gambling Quantity and Perceived Norms Scale (GQPN), the Gambling Problem Index (GPI), and the Gambling Readiness to Change Questionnaire (GRTC).The study consisted of 560 undergraduate college students who completed a survey including the newly constructed measures and other measures designed to assess convergent validity. Results confirmed good reliability and convergent validity of all three measures. Implications for evaluating efficacy of treatment and prevention interventions are detailed. 相似文献

Ecological risk-benefit analysis of a wetland development based on risk assessment using "expected loss of biodiversity". 总被引:3,自引:0,他引:3
Ecological risk from the development of a wetland is assessed quantitatively by means of a new risk measure, expected loss of biodiversity (ELB). ELB is defined as the weighted sum of the increments in the probabilities of extinction of the species living in the wetland due to its loss. The weighting for a particular species is calculated according to the length of the branch on the phylogenetic tree that will be lost if the species becomes extinct. The length of the branch on the phylogenetic tree is regarded as reflecting the extent of contribution of the species to the taxonomic diversity of the world of living things. The increments in the probabilities of extinction are calculated by a simulation used for making the Red List for vascular plants in Japan. The resulting ELB for the loss of Nakaikemi wetland is 9,200 years. This result is combined with the economic costs for conservation of the wetland to produce a value for the indicator of the "cost per unit of biodiversity saved." Depending on the scenario, the value is 13,000 yen per year-ELB or 110,000 to 420,000 yen per year-ELB (1 US dollar = 110 yen in 1999). 相似文献

着重考察了苏轼在<东坡易传>中对"道"与"性"的论述,发掘了其易学哲学在本体论上的内涵,即以佛道解道、性;与认识论上的内涵,即以庄解道、性.并指出苏轼易学哲学的特点在于"诸家并举,会而不通".其"不通"主要表现在本体层面的佛道之学与伦理层面的儒学之间的不通,而苏轼所心仪之庄学的认识论意义与理论宽容精神正好成全了这种"会而不通". 相似文献

Companies throughout industry are interested in retaining existing customers, because customers' continuous consumption of products and services is critical to the long‐term value propositions of most organizations. Thus, decision‐making strategies that promote continuous use and customer retention are of research interest, both theoretically and practically. In the present research, we investigate one important area of continuous usage, that of Web site use. In particular, we use several theories of commitment to understand how an individual's decision to continue to use a Web site is influenced by his or her commitment toward that Web site and the vendor that supports it. Results derived from data collected from 335 users of a variety of Web sites indicated that affective commitment, calculative commitment, quality of alternatives, and trust were significantly associated with an individual's behavioral intention to continue to use a Web site. Implications for customer retention and decision‐making strategies are discussed. 相似文献

A value mapping for cooperative games with transferable utilities is a mapping that assigns to every game a set of vectors each representing a distribution of the payoffs. A value mapping
is efficient if to every game it assigns a set of vectors which components all sum up to the worth that can be obtained by all players
cooperating together.? An approach to efficiently allocate the worth of the ‘grand coalition’ is using share mappings which assign to every game a set of share vectors being vectors which components sum up to one. Every component of a share vector is the corresponding players' share in the
total payoff that is to be distributed among the players. In this paper we discuss a class of share mappings containing the
(Shapley) share-core, the Banzhaf share-core and the Large Banzhaf share-core, and provide characterizations of this class of share mappings.

Abstract Building on previous theory and research, we propose a “structural relational” view of the sex gap in small business success. Our findings, based on analyses of data from 423 small business owners in Iowa, show support for our model and suggest that links between owners, social relational processes, business structure, and small business success operate differently depending on the industry location of the business and the owner's sex. Results also indicate that the business owner's sex has direct and indirect effects on business success. This finding suggests that social relations, organizations, and institutions are all gendered in ways that influence the sex gap in sales, but that further research is needed to more fully explain sex differences in small business success. We discuss these and other findings in terms of their theoretical and practical implications, and suggest directions for future research. 相似文献

Two conceptual models are proposed in this article—one for work discrimination and the other for discrimination coping strategies pertaining to lesbian, gay, and bisexual workers. The work discrimination model includes 3 dimensions (formal vs. informal, potential vs. encountered, and perceived vs. real). The coping strategies model outlines methods that deal with potential and encountered discriminations. It includes vocational choice and work adjustment strategies; the latter are further categorized under identity management or discrimination management strategies. 相似文献

We propose a generalization of expected utility that we call generalized EU (GEU), where a decision maker’s beliefs are represented by plausibility measures and the decision maker’s tastes are represented
by general (i.e., not necessarily real-valued) utility functions. We show that every agent, “rational” or not, can be modeled
as a GEU maximizer. We then show that we can customize GEU by selectively imposing just the constraints we want. In particular,
we show how each of Savage’s postulates corresponds to constraints on GEU. 相似文献
