Ken C. Winters Ph.D. Randy D. Stinchfield Ph.D. Jayne Fulkerson M.A. 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》1993,9(1):63-84
The development and initial psychometric properties of an adolescent gambling problem severity measure are described. The scale, based on a revision of the South Oaks Gambling Screen (Lesieur & Blume, 1987), was administered to 1,101 older (ages 15 to 18) Minnesota adolescents as part of a state-wide gambling survey. Study results indicated that the scale had moderate internal consistency reliability and was significantly related to alternate measures of problem severity for male subjects. Because the rate and severity of gambling among females was very low, the psychometric adequacy of the scale for females is not known at this time. The implications of study findings to the conceptual understanding of adolescent gambling problem severity as well as study limitations and future research needs, are discussed.Support for the study was provided by the Minnesota Department of Human Services and the Center for Addiction Studies, University of Minnesota, Duluth. The authors gratefully acknowledge the assistance from Robert Blum, Linda Harris, Durand Jacobs, J. Laundergan, Alan Mathiason, Brenda Miller, James Schaefer, school officials from the participating high schools, and interviewers who assisted with the telephone survey. 相似文献

Ego building is essentially a name given to a variety of interventions used to support an ego hampered by regression or deviation. The term has its roots in the concept of ego support but evolved specifically as a technical term in contemporary ego psychology closely connected with the developmental theory of separation individuation. Using four vignettes of psychotherapy work with children all of whom suffered from unresolved conflicts and developmental interferences from the separation-individuation process, an attempt is made to illustrate the technical place of ego building in psychotherapy with children. It is suggested that the use of ego building, particularly verbalizing adaptive aims facilitates an alliance, supports a safety feeling and positive self-esteem. This contributes to providing a treatment experience that reduces over-stimulation and anxiety and frees the expression and understanding of aggression which ultimately promotes separation-individuation.in private practice.This paper was presented at the Conference on the Continuing Evolution of Psychoanalytic Thought: Infancy to Adulthood, N.Y.C., Nov. 1990., sponsored by the Committee on Psychoanalysis of the National Federation of Societies for Clinical Social Work. 相似文献

This article compares in regression models the effects of occupational status of both fathers and mothers simultaneously upon the attainment of men and women in the Irish Republic. The sample matches male respondents from the 1973/1974 Irish Mobility Study with the labour active female sibling next closest in age. Since the analysis compares working siblings and each 'matched pair' shares the same family origin characteristics, the problems attendant upon using a sample originally of men only are partially avoided. The results advance beyond previous research since, rather than separate models by gender, models include parents and children of both genders, allowing direct rather than indirect evaluation of gender-based determinants of occupational attainment. Both fathers and mothers significantly affect children's attainment, in ways that vary by the child's gender. The results highlight the salience of mothers' attainment for their children and question the 'mainstream' model of equivalent mechanisms of occupational attainment for both genders. Models of social mobility that consider men and women as special instances of a general perspective provide the most fruitful approach for further development. 相似文献

Russia’s role in ‘animation’ of the Kyoto Protocol was crucial. Its initial vacillation on ratification was predominantly
due to political bargaining with the EU. Domestic economic rationales [i.e. impacts of emission trading and Joint Implementation
(JI) projects] were important to a much lesser extent and environmental motives did not seem to play any role in the decision.
Since the Protocol entered into force, there have been significant delays in complete establishment of policy implementation
frameworks, which are necessary for Russia to start benefiting from JI and emission trading. Only recently, in 2007, have
GHG inventories and a national registry been established and the responsibilities for implementation of the Protocol and JI
among the government departments have been distributed only to a certain extent. Some constraints hindering JI projects, such
as vague legislation, an unfavourable economic climate, lack of commitment to JI projects, corruption, xenophobia, state and
agency ‘capture’ still remain.

In Sweden, government-mandated paid parental leave has been available to both mothers and fathers since 1974. By 2006, each parent had two non-transferable leave months and nine additional months to share. From the beginning, parental leave was presented as a policy designed to promote gender equality, with women and men having equal opportunities and responsibilities to contribute economically to the family and care for children. Sweden thus provides a unique setting to explore whether social policy can be an important instrument for changing the gender contract. Analysing survey data from 356 fathers working in large private companies, we found that the amount of parental leave days taken had positive effects on several aspects of fathers’ participation in childcare and on their satisfaction with contact with children, controlling for other factors contributing to fathers’ participation in childcare. Our findings suggest that the full potential of Sweden's parental leave policy for degendering the division of labour for childcare will not likely be met until fathers are strongly encouraged by social policy to take a more equal portion of parental leave. 相似文献

This article contributes to the ongoing debate on the economic determinants of fertility behavior by addressing the role of
job insecurity in couples’ intentions concerning parenthood and its timing. It starts from the hypothesis that cultural values
moderate individuals’ reactions to job insecurity and the way it is related to family formation. With a systematic thematic
content analysis of a set of semi-structured interviews with childless men and women around the age of 30 in eastern and western
Germany, we are able to show that there are substantial differences in the consequences of job insecurity on intentions to
have a first child. In western Germany, a relatively secure job career is expected to precede family formation, and this sequence
of transitions is rather rigid, whereas in eastern Germany job security and family formation are thought of and practiced
as parallel investments. We suggest that the lack of convergence in family formation patterns between eastern and western
Germany after the unification of the country in 1990 is partially related to different attitudes toward job insecurity in
the two contexts. 相似文献

This paper proposes an experimental test to evaluate the performance of the serial cost sharing rule, originally proposed
by Shenker [Sigmetrics, 241–242 (1990)] and then analyzed by Moulin and Shenker [Econometrica 60, 1009–1037 (1992)]. We report
measures of the performance and efficiency of the serial mechanism by comparing the choices and payoffs attained by the subjects
to the expected equilibrium allocations. Experimental evidence shows that learning is needed for the subjects to converge
to the equilibrium strategy. However, in terms of efficiency, the serial mechanism leads to almost efficient allocations. 相似文献
