It is generally difficult to separate the effects of divorce from selection when analyzing the effects of parental divorce on children’s risk behaviors. We used propensity score matching and longitudinal data methods to estimate the effects of parents’ divorce on their children’s binge drinking, alcohol consumption, tobacco use, marijuana use, and hard drug use. The children were between 12 and 18 years old in the first survey and between 18 and 24 years old in the second survey. Our results suggest that parental divorce significantly increased the probability of risk behaviors in their children. Moreover, many of these adverse impacts persisted over time, especially among teenage girls.  相似文献

This article provides my reflections and comments on the meta-analysis of situational crisis communication theory (SCCT) presented in this issue. The meta-analysis helps to crystallize strengths and weaknesses of SCCT and the research generated by the theory. No theory is perfect and every theory has limitations/boundaries. The meta-analysis helps to identify the boundaries for SCCT helping to understand when the theory works and when there are better options for informing crisis communication. By reflecting on the extant research, we can plot the direction for future research utilizing SCCT.  相似文献

Analytic and conceptual ambiguity associated with the study of legitimacy have motivated debates over the utility of this construct in the analysis of violent political conflict. Using these debates as a point of departure, I review several challenges that have limited the study of legitimacy in this area and discuss two features of legitimation that have gone widely overlooked: (i) the asymmetric causes and effects of legitimacy and illegitimacy, and (ii) the relational dynamics of legitimation. I argue that turning explicit analytic attention to the asymmetry and relationality of legitimacy and illegitimacy allows us to overcome the most intractable challenges associated with the analysis of legitimation in violent conflict.  相似文献

Do men and women carry different motivations for entering self-employment? Earlier researchers have suggested that, as primary care givers for children and families, women face a more stringent time constraint relative to men. Thus, where men see self-employment as a chance for greater financial opportunity, women see a chance to take work that allows more time at home. This paper investigates this hypothesis using unique data that allow analysis of individual self-employment as a function of traditional economic and demographic variables as well as variables that partially capture individuals’ opinions and perceptions of pecuniary and nonpecuniary aspects of entrepreneurism. Results suggest that men who choose self-employment are influenced principally by pecuniary concerns, while women are influenced principally by family concerns and by the opinions of their family, friends, and peers.  相似文献

Autism spectrum disorder (ASD) does not only affect the child alone, but the family unit as well. This qualitative study explored the impacts of ASD on the relationship between parents and their neuro-typical children and how the neuro-typical children cope with the impacts of having an autistic sibling in the family. Utilising principles of the social relations theory, five Singaporean families (n = 10) consisting of five mothers and five neuro-typical children were interviewed. Both the mothers and the neuro-typical children were seen to be equal agents in influencing the interactions with each other, and contributed in maintaining the close relationship through various strategies. Findings revealed that having an autistic child in the family imposed certain constraints and additional responsibilities for the family members. Despite so, the neuro-typical children coped well with such constraints. The in-depth data highlight the value of considering both the agency of mothers and the neuro-typical children and how they bidirectionally influence each other while sharing the caregiving roles for the autistic child in the family. It is strongly recommended for practitioners to incorporate elements of child's agency when expanding their scope of psychosocial intervention work with the neuro-typical children.  相似文献

Despite popular claims that racism and discrimination are no longer salient issues in contemporary society, racial minorities continue to experience disparate treatment in everyday public interactions. The context of full-service restaurants is one such public setting wherein racial minority patrons, African Americans in particular, encounter racial prejudices and discriminate treatment. To further understand the causes of such discriminate treatment within the restaurant context, this article analyzes primary survey data derived from a community sample of servers (N = 200) to assess the explanatory power of one posited explanation—statistical discrimination. Taken as a whole, findings suggest that while a statistical discrimination framework toward understanding variability in servers’ discriminatory behaviors should not be disregarded, the framework’s explanatory utility is limited. Servers’ inferences about the potential profitability of waiting on customers across racial groups explain little of the overall variation in subjects’ self-reported discriminatory behaviors, thus suggesting that other factors not explored in this research are clearly operating and should be the focus of future inquires.  相似文献

Lesbian, gay, and bisexual (LGB) youths are over-represented in the homeless population. To examine why some LGB youths become homeless, this report compares homeless and non-homeless LGB youths. Of the 156 LGB youths, 48% reported ever being homeless (i.e., running away or being evicted from home). Results indicate that sexual orientation awareness and the initiation of sexual behavior occurred earlier in homeless than in non-homeless LGB youths and predated the first homeless episode. Substance use was more frequent and first occurred at an earlier age in homeless as compared to non-homeless LGB youths; however, substance use occurred subsequent to first homelessness. Childhood sexual abuse was associated with homelessness; and, early sexual orientation development was related to homelessness among youths without a history of sexual abuse. Findings suggest that interventions should help youths cope with their unfolding sexual orientation and work to prevent or address the consequences of sexual abuse.  相似文献

About 50?years ago, Efron noted some counterintuitive properties of the long-term behavior of contests involving dice. For instance, consider the 6-sided dice whose sides are labeled (4,4,4,4,0,0), (3,3,3,3,3,3), (6,6,2,2,2,2), and (5,5,5,1,1,1). Each die has a 2/3 probability of rolling a higher number than the next one in the list and the last has the same 2/3 probability of rolling a higher number than the first. The non-transitivity of games involving non-identical dice was popularized by Gardner (Sci Am, 223:110–114, 1970). Although Gardner and other authors have observed that non-transitive dice serve to illustrate the complexities of the theory of voting, it does not seem that much attention has been paid to the corresponding voting system. Our purpose in this article is to present this voting system and compare its properties with those of other voting systems. One of the most interesting properties is the fact that cancellation with respect to the Efron dice voting system can replace cancellation with respect to pairwise preferences in Young’s characterization of the social choice function associated with the Borda Count.  相似文献
