Towards the end of counselling with Steven, a 13‐year‐old Aboriginal adolescent, he dreamed of being lost at sea and then found by a white whale. The whale carried him to safety; specifically, into the care of his current foster family. This ending is full of symbolism and seems to promise positive and uncomplicated outcomes. However, counselling is rarely straightforward, and this case study is no exception. It explores a complex journey though therapy, full of challenges and discomfort, not only for Steven and myself, but also for the variety of other supportive players in his life. The outcome, although nowhere near as dramatic as his dream, I believe reflects meaningful change for this young man.  相似文献

Knowing when to compete and when to cooperate to maximize opportunities for equal access to activities and materials in groups is critical to children's social and cognitive development. The present study examined the individual (gender, social competence) and contextual factors (gender context) that may determine why some children are more successful than others. One hundred and fifty‐six children (M age=6.5 years) were divided into 39 groups of four and videotaped while engaged in a task that required them to cooperate in order to view cartoons. Children within all groups were unfamiliar to one another. Groups varied in gender composition (all girls, all boys, or mixed‐sex) and social competence (high vs. low). Group composition by gender interaction effects were found. Girls were most successful at gaining viewing time in same‐sex groups, and least successful in mixed‐sex groups. Conversely, boys were least successful in same‐sex groups and most successful in mixed‐sex groups. Similar results were also found at the group level of analysis; however, the way in which the resources were distributed differed as a function of group type. Same‐sex girl groups were inequitable but efficient whereas same‐sex boy groups were more equitable than mixed groups but inefficient compared to same‐sex girl groups. Social competence did not influence children's behavior. The findings from the present study highlight the effect of gender context on cooperation and competition and the relevance of adopting an unfamiliar peer paradigm when investigating children's social behavior.  相似文献

In this paper we describe a semiparametric information‐theoretic framework for modeling the determinants of rare events aggregated at intracity areal units while allowing for various forms of error correlation structures. The approach is applied to an examination of the effects of socioeconomic and demographic macrocharacteristics of communities on the amount of violence they experience. We investigate and find evidence of some instability in these processes across types of violence and level of areal aggregation. However, we also find evidence of a stable predictor—resource deprivation—for all the types of violence analyzed and at both levels of areal aggregation considered. In addition, we find evidence of a spillover effect of a community's resource deprivation on the level of violence its neighboring areas can expect. We discuss our findings in light of their substantive, methodological, and practical implications.  相似文献

The authors define a class of “partially linear single‐index” survival models that are more flexible than the classical proportional hazards regression models in their treatment of covariates. The latter enter the proposed model either via a parametric linear form or a nonparametric single‐index form. It is then possible to model both linear and functional effects of covariates on the logarithm of the hazard function and if necessary, to reduce the dimensionality of multiple covariates via the single‐index component. The partially linear hazards model and the single‐index hazards model are special cases of the proposed model. The authors develop a likelihood‐based inference to estimate the model components via an iterative algorithm. They establish an asymptotic distribution theory for the proposed estimators, examine their finite‐sample behaviour through simulation, and use a set of real data to illustrate their approach.  相似文献

Recursive estimates of a probability density function (pdf) are known. This paper presents recursive estimates of a derivative of any desired order of a pdf. Let f be a pdf on the real line and p?0 be any desired integer. Based on a random sample of size n from f, estimators f(p)n of f(p), the pth order derivatives of f, are exhibited. These estimators are of the form n?1∑nj=1δjp, where δjp depends only on p and the jth observation in the sample, and hence can be computed recursively as the sample size increases. These estimators are shown to be asymptotically unbiased, mean square consistent and strongly consistent, both at a point and uniformly on the real line. For pointwise properties, the conditions on f(p) have been weakened with a little stronger assumption on the kernel function.  相似文献

Previous research has indicated that individual compensating behavior, specifically, more risky driving may reduce the effectiveness of seat belt laws. We test the compensating-behavior hypothesis using individual-specific survey data. The analysis also incorporates individual risk tastes. Our results indicate that the compensating-behavior hypothesis applies only to those that are not strongly risk averse. Other risk-differentiated groups do not exhibit compensating behavior. Finally, it seems that individuals learn to reduce compensating behavior over time.  相似文献

This case study describes the growth and development of Singapore Airlines from a small national carrier serving the Malayan States to an international airline with a network extending to 27 countries. Its strategy is simple: quality service at a competitive price, made possible by high investment in equipment and in staff training.  相似文献
