Relationships among three motivational variables (negative-personal functions of drinking, alienation, and perceived discrepancies between valued goals and expected success toward valued goals) were evaluated in a group of 257 college drinkers. As predicted, a positive relationship between alienation scores and the extent of discrepancies between values and expectations for academic and social success was found. Negative-personal drinking functions were positively associated with both alienation and value-expectation discrepancies. Results are discussed in terms of heuristic consistency and potential applications.  相似文献

The design, aims and rationale are outlined of a follow-up study of dropouts from Gamblers Anonymous. A cohort of those attending for the first time and dropping out after more than one meeting was contacted and the cooperators given a structured interview examining factors which may have contributed to decisions to dropout. A comparison group of continuers from the same meeting who had been totally abstinent for at least a year were given the same structured interviews. This first of four parts examines life context factors making it more difficult to maintain attendance, commitment to the treatment program, perceived pre-meeting expectations and reasons for coming, impacts of the first meeting, effects of pressures to maintain attendance and the influence of spouses.  相似文献

Iron and steel is a key industry in the Indian economy. The author looks at the prospects into the next century and the options facing the industry over the next two decades. New capacity will have to be undertaken but it will undoubtedly be difficult to fund this without external assistance and without diverting resources from other areas. Thus it will be necessary to plan for technological innovation to achieve production objectives, and such technology must be developed in India, or imported and adapted to suit indigenous conditions.  相似文献

If investors' attitudes toward risk are sufficiently similar to admit an efficient sharing rule that is linear, then this rule also provides sufficient incentives for truthful revelation of private information relevant for joint production decisions.Research support from the Office of Naval Research contract ONR-N00014-79-C-0685 and the National Science Foundation grants SOC-75-21820 and SES-81-08226 is gratefully acknowledged.

Many theories of geographic mobility assume that the change-of-residence process includes a substantial degree of choice. This paper classifies stated reasons for moving from the 1973 through 1977 Annual Housing Survey into forced, imposed, and preference-dominated categories. About 25 percent of residential mobility and 40 percent of migration occurred under conditions of substantial constraint. Mobility was most often constrained by family dynamics; for migration, occupational relocations frequently imposed the decision-to-move process and determined destinations. The volume of constrained movement indicates that its impact upon individuals, population dynamics, and voluntaristic theories of mobility deserves greater consideration.  相似文献

This article investigates circumstances under which seven important martingale properties are preserved by the following six martingale generalizations: quasimartingales, amarts, martingales in the limit, games fairer with time, progressive martingales, and eventual martingales.  相似文献

The FTC initially considered two forms of regulation in the used automobile market, requiring dealers to either certify or warrant the mechanical condition of each automobile sold. Since the regulation would have been imposed only on dealers and not on private sellers, its effectiveness was dependent on the magnitude of the induced shift of sales into the private market. Accordingly, this paper employs a gametheoretic model to examine the theoretical conditions under which society could be expected to benefit from either regulatory alternative. Among other things, it is concluded that a socially beneficial minimum quality standard may not exist in some situations.  相似文献

Ce texte examine l'étude faite par le professeur Cuneo sur la relation entre l'exploitation des classes et les conflits manifestes entre les classes au Canada. Nous démontrons que la thèse de Cuneo selon laquelle il existe une relation positive entre ces variables est fausse, étant donné que pour arriver à ses indices, Cuneo s'est servi de statistiques erronnées sur le taux de plus-value, les grèves et les lock-outs.
Profesor Cuneo's study of the relation between class exploitation and overt class conflict in Canada is examined. We show that his finding of a positive relation between these variables is based on errors in constructing his indices of the rate of surplus value and strike and lockout activity.  相似文献
