A sample of 63 licensed foster parents who had fostered a child who was diagnosed with a disorder in the fetal alcohol spectrum were asked “What would make you consider ending a placement with a child who has a fetal alcohol spectrum disorder?” The responses to this question were grouped together by foster parents. The grouping data were subjected to multidimensional scaling and cluster analysis. Results indicated that foster parents would consider ending a placement if they felt they were being taken for granted, burned out, had insufficient information about the child, or if the child had serious behavior problems, caused harm to others in the home, or did not comply with household rules and routines. Discrepancies between the literature and study results were described and suggestions for future research were made. 相似文献

Perceptions of good parent–adolescent relationships were explored among 19 Mexican American high school students aged 14–17 who participated in focus group interviews on what it means for Mexican American teenagers to have good relationships with parents. Using a grounded theory approach, five general themes emerged in the responses, corresponding to open communication, instrumental and emotional support, indirect expressions of caring, parental control, and valued relationship qualities. Both genders described distinct relationships with mothers and fathers. Relationships with mothers were closer and more open than relationships with fathers, and mothers were seen as being more affectionate, lenient, and emotionally supportive, whereas fathers tended to express caring indirectly by providing instrumental and financial support and by just being there. Parental upbringing, culture, gender, and parental role expectations emerged as explanations for parents' behavior. Theoretical, methodological, and practical implications are discussed. 相似文献

Abstract This paper investigates the organization of household economic behavior in post‐socialist rural Hungary. Data from 751 randomly selected households in three rural regions of the country showed weak labor force attachment and heavy reliance on social welfare programs among these households. Self‐provisioning and interhousehold exchange were also prevalent. The data showed that interhousehold exchange is motivated by both economic and social logics. Interhousehold exchange appears to be more likely among better‐off households with more economic and social resources. 相似文献

We develop a theoretical framework to examine how government organization affects its power and size. The framework abstracts from distortions that arise from the means of government finance and separates government power into two dimensions—pure coercive power and pure pricing power. A government can exert its coercive power to shift the demand for its services outward and grow too large. It can simultaneously exert its pricing power to restrict output along a given demand curve to earn rents. Consequently, neither size nor rents alone are reliable indicators of the extent to which government provision of services is nonoptimal. 相似文献

The Kruskal–Wallis test is a rank–based one way ANOVA. Its test statistic is shown here to be a quadratic form among the Mann–Whitney or Kendall tau concordance measures between pairs of treatments. But the full set of such concordance measures has more degrees of freedom than the Kruskal–Wallis test uses, and the independent surplus is attributable to circularity, or non–transitive effects. The meaning of circularity is well illustrated by Efron dice. The cases of k = 3, 4 treatments are analysed thoroughly in this paper, which also shows how the full sum of squares among all concordance measures can be decomposed into uncorrelated transitive and non–transitive circularity effects. A multiple comparisons procedure based on patterns of transitive orderings among treatments is implemented. The testing of circularities involves non–standard asymptotic distributions. The asymptotic theory is deferred, but Monte Carlo permutation tests are easy to implement. 相似文献

Adaptive cluster sampling can be a useful design for surveying rare and clustered populations. Here we present a new development in adaptive cluster sampling where we use a two‐stage design and extend the complete allocation sampling method. In the proposed new design the primary sample units are selected and, depending on the value of a preset condition, the entire primary unit is surveyed, as in complete allocation sampling. In the next step, if a second condition is met, the surrounding primary sample units are selected. We review the efficiency of the proposed design for sampling the New Zealand Castle Hill buttercups and provide unbiased estimators for the population total and sampling variance. 相似文献

Destruction, notes David Harvey, “is often required to make the new urban geography out of the wreckage of the old.”2 The history of San Francisco's Chinatown following the 1906 earthquake and fire and New Orleans' public housing following Hurricane Katrina in 2005 reveal how powerful class interests collude with the fog of disaster to lay claim to the urban spaces of the poor and marginal. In two historic U.S. disasters we witness the concerted efforts of urban elites to confiscate the spaces of two politically vulnerable populations: the Chinese in 1906 and low‐income African‐Americans in 2005. The widely varying outcomes of these two attempts reveal a good deal about the intersection of calamity, class, race, and citizenship in American history. 相似文献

We simulated the commercially available multi-line slot machine game “Money Storm,” including its bonus wins. Our results show that after a specified amount of time (such as 1 or 50 h), when players played a single line, there were marked differences between one player and the next—a few won a lot, others lost far more than average. When playing 20 lines there were fewer big winners and fewer players quickly losing a large percentage of their money. We simulated a Gambler’s Ruin scenario whereby players arrived with $100 and made $1 wagers until broke. Again we saw a reduction in the variability among player as the number of lines wagered increased, fewer players lost their entire bankroll quickly, and fewer players had big wins. The bonus wins in Money Storm contribute approximately 24 % to the payback of the game, and our simulations of bonus wins shows that with 20 lines wagered the players spend approximately 11 % of their time in bonus wins. With one line wagered, there are no losses disguised as wins while with 20 lines wagered the majority of hits are losses disguised as wins. Players using multi-line machines can thus tune the characteristics of the machine gambling experience to match their preferred pattern, though most seem in practice to bet on the most possible lines. Our results serve to inform researchers, counsellors, gamblers and others about how slot machines are designed, and the effect that wagering on multiple lines has on short-term and long-term play, bonus wins, and losses disguised as wins. 相似文献

Using multi‐informant data drawn from a prospective study involving 184 youth, mother‐perpetrated and father‐perpetrated partner aggression during early adolescence (the age of 13) was examined as a predictor of five types of disengagement coping strategies in emerging adulthood (the age of 21): behavioral disengagement, mental disengagement, denial, substance use, and restraint. The ability to develop close friendships, or friendship competence, was examined as a moderator of these links. Results suggest that inter‐parent aggression in early adolescence can predict reliance on disengagement coping 8 years later, but that friendship competence can buffer against the reliance on disengagement coping. Moreover, close friendship competence was not directly related to partner aggression by mothers or fathers, suggesting that friendship competence develops along an independent developmental track and thus may truly serve as a buffer for young adults with a history of exposure to inter‐parent aggression. 相似文献

This article will examine the parenting characteristics and challenges that faced a cohort of families participating in an exploratory qualitative research study. This study sought to describe the experiences and characteristics of parents whose children were placed in the child welfare system in early-to-late adolescence (ages 12–18), thus gaining an understanding of the parenting challenges faced as they were able to maintain their children in their homes for a significant portion of their lives. The families of older youths entering care for the first time described how alcohol and drug abuse impacted their relationships with children, significant others, jobs, and their mental health status. A significant issue that emerged in several of the cases were older children who initiated a report to child welfare themselves. 相似文献
