Risk-taking/gambling-like behavior in preschool children 总被引:2,自引:0,他引:2

The types and characteristics of risk-taking or gambling-like behaviors in children are not well understood. Social learning, as one potential etiological factor of risktaking behavior in preschool children, was empirically examined. Prior to playing a risk-taking game, children in the experimental group were exposed to a peer model who had ostensibly won a large prize, whereas control children were exposed to a peer model who had won nothing. Children in the experimental group initiated more risks to win the large prize in the high-risk situation than children in the control group. The results indicated that modeling can enhance risk-taking/gambling-like behavior in young children. Parallels to compulsive gambling in adults, and recommendations for future research were also discussed.The authors wish to thank Melissa Warren and Earlene Goodman for their valuable assistance during the course of this study.Portions of this paper were presented at the meeting of the Western Psychological Association, San Francisco, CA 1991. 相似文献

Throughout the Western world governments have been obliged to address the tension between the continuously rising cost of publicly-financed health care and the perceived need to restrain aggregate public expenditure. In several countries recent developments have included attempts to apply ‘performance indicators’ to health care programmes. This paper examines the nature of the main US and UK indicators and argues that, though they may help to legitimate expenditure restraint, they will probably tell us little about the effectiveness (or even efficiency) of present practice. Some directions are indicated for an alternative approach to performance measurement. 相似文献

Comte's philosophy of science is re-examined from the point of view of the rationalist problematic of the unity of knowledge. It is argued that Comte's attempt to answer this metaphysical problem is the single most important factor determining the final form of his system of positive philosophy, his hierarchy of the sciences, his conception of sociology, and ultimately his positive religion of Humanity. After rejecting the main solutions offered by modern rationalism, Comte provides a subjective unity for the sciences by establishing Humanity as the principle of organization for all knowledge. The article describes the various components of the positive synthesis, their background in the history of ideas, and the contemporary relevance of the problem of unity for logical empiricism and Husserl. Some have said that need for unity expresses the identity of the self; others, that it stands for economy of thought. Possibly, but this is interpretation, psychologically or sociologically tinged. The need for unity is a historical fact and, as such, unresolved. It is also a symbol of science, and its myth. Science is a finely defined and articulated system of symbols; but the ultimate symbol, that of unity, can have no referent. Rather one might say it stands for the totality of the knowable and the unknowable. A confusing situation for the scientific mind, but one it cannot escape. For the conflict at the heart of rationalism is the source of its strength, as long as it lasts. Once the faith is lost, something else has to be found. Under the relentless pressure of social change, with the growing operationalism of physical theory and the metaphysical devastations attendant on Darwinism, the myth of unity could no longer hold. It had to be replaced by unification. But with that the status of science is changed and also that of the scientist. The mirror of nature that reason had endeavored to build up through the ages is shattered, and we look for the first time straight out into an unknown world. 相似文献

Family-Directed Structural Therapy (FDST) is an approach to family therapy built on traditional concepts of Structural Family Therapy, the Strengths Model, and Group Work Theory. The FDST approach is a goal-oriented, time limited approach that enables the family to identify strengths and areas of concern, as well as to enhance family functioning. This process is facilitated via the use of a common vocabulary and a concretely organized, easily administered FDST Assessment Tool that is completed by adult family members. This article presents the essential features of the FDST approach, including the use and scoring of the FDST Assessment Tool. It concludes with an extensive case example. 相似文献

The Transtheoretical Model has been recently applied to men seeking services at battering intervention and prevention programs (Eckhardt, Babcock, & Homack, 2004; Murphy & Baxter, 1997). This study considers whether women arrested for intimate partner violence differ from male perpetrators in terms of stages of change and processes of change. No gender differences were found regarding stage of change. In general, all individuals presenting for treatment were in the early stages of change. The use of various processes of change was strongly related to stage of change, with individuals in the more advanced stages of change using more behavioral and experiential strategies to become nonviolent. However, except for the use of social liberation strategies, there were no gender differences in the use of the various processes. These findings suggest that the Transtheoretical Model may apply to female perpetrators equally as well as to male perpetrators. Intervention programs designed for male batterers using the Transtheoretical Model may also be helpful in the treatment of women arrested for domestic violence. 相似文献

This study provides additional information about casino gambling practices in two adolescent samples. Specifically, 109 adolescents from a religious high school and 84 adolescents from a juvenile detention facility in Las Vegas, Nevada were surveyed. Of these, 71 (36.8%) were found to gamble regularly (58 males, 13 females, mean age 15.9 years). Results indicated many similarities among the two groups. The overall sample appeared to have a strong affinity for casino gambling, were diverse in their practices and reasons for gambling, reported a variety of emotional and physiological behaviors when gambling, occasionally experienced problems from casino gambling, and had parents who generally approved and were aware of their children's gambling behavior. The accessibility and family-oriented nature of many new casinos may be responsible for these effects.The authors thank Nicole Giangregorio and Ned C. Silver for their assistance.

An internal pilot with interim analysis (IPIA) design combines interim power analysis (an internal pilot) with interim data analysis (two-stage group sequential). We provide IPIA methods for single df hypotheses within the Gaussian general linear model, including one and two group t tests. The design allows early stopping for efficacy and futility while also re-estimating sample size based on an interim variance estimate. Study planning in small samples requires the exact and computable forms reported here. The formulation gives fast and accurate calculations of power, Type I error rate, and expected sample size. 相似文献

For the analysis of survey-weighted categorical data, one recommended method of analysis is a log-rate model. For each cell in a contingency table, the survey weights are averaged across subjects and incorporated into an offset for a loglinear model. Supposedly, one can then proceed with the analysis of unweighted observed cell counts. We provide theoretical and simulation-based evidence to show that the log-rate analysis is not an effective statistical analysis method and should not be used in general. The root of the problem is in its failure to properly account for variability in the individual weights within cells of a contingency table. This results in goodness-of-fit tests that have higher-than-nominal error rates and confidence intervals for odds ratios that have lower-than-nominal coverage. 相似文献

The problem of selecting the Bernoulli population which has the highest "success" probability is considered. It has been noted in several articles that the probability of a correct selection is the same, uniformly in the Bernoulli p-vector (P1,P2,….,Pk), for two or more different selection procedures. We give a general theorem which explains this phenomenon. An application of particular interest arises when "strong" curtailment of a single-stage procedure (as introduced by Bechhofer and Kulkarni (1982a) )is employed; the corresponding result for "weak" curtailment of a single-stage procedure needs no proof. The use of strong curtailment in place of weak curtailment requires no more (and usually many less) observations to achieve the same. 相似文献
