Using family stress theory, this study examined the relationship between adolescent reports of selected demographic variables (gender, age, family form), interparental conflict (style, content, intensity, resolution), stress due to the pileup of stressors, coping strategies (social support, detrimental coping), and adolescent family life satisfaction. The sample was comprised of 155 adolescents ranging from 14 to 18 years of age who completed self-report questionnaires at one of three rural Oklahoma high schools. Four dimensions of interparental conflict (overt conflict style, conflict about childrearing, conflict about family roles/finances, conflict resolution), stress due to pileup, social support coping, and detrimental coping were significantly related to family life satisfaction. Adolescent age was positively related to family life satisfaction. Within the scope of family stress theory, scholars have addressed how the combination of stressors and coping strategies relates to the adaptation of individuals within family systems (McCubbin and Patterson 1983). Further, investigations of the relationship of parental divorce to well-being in children and adolescents suggest that interaction patterns within various family forms may be more fruitful in explaining the adaptation of youth than parental marital status (Demo 1992). The perception by youth of conflict between their parents (i.e., interparental conflict) has emerged as a key family stressor that has the potential to explain variation in adolescent adaptation in a variety of family forms (Buehler, Krishnakumar, Anthony, Tittsworth, and Stone 1994). Stressor events for adolescents such as interparental conflict generally do not occur in isolation. Rather, they exist within the context of other stressors such as economic stress, difficulties at school, or normative developmental tasks for families with adolescents (e.g., changing family roles to allow greater adolescent autonomy; McCubbin and Patterson 1986). Further, considerable variation exists in the coping strategies (e.g., social support, avoidance) that adolescents use in response to stress (McCubbin and Patterson 1986). Finally, previous research shows variation between certain demographic variables and adolescent adaptation. Thus, the current study was developed to examine how selected demographic variables (gender, age, family form), adolescent perceptions of interparental conflict (style, content, intensity, degree of resolution), stress based on the pileup of stressor events, and coping strategies relate to adolescent satisfaction with family life (one indicator of adaptation).  相似文献

Language is a communication medium for turning a power base into influence. But more than that, the creation of power and its maintenance or change can also occur in and through language. In the present article, we discuss some of the dynamic links between language and power to underscore their relevance to the study of intergroup relations. In particular we address the means by which low-power groups might achieve power, and how those who are in high-power positions might retain and subvert acts of power. In doing this, we counterpose our discussion with research that addresses these same issues from a static and individualistic approach to power. Our central argument is that the latter work lacks theoretical facility for describing and understanding the aforementioned dynamic processes of power, and moreover, that its application may unwittingly serve to reify and cement existing control relationships.  相似文献

Liverpool, U.K., 1863--1900, has been used as a model to explore the interaction between measles epidemics and the population dynamics in an overcrowded community with inadequate nutrition using a non-linear model which allows the estimation of certain underlying demographic parameters. The results are consistent with a system that is driven by an oscillation in the transmission parameter that is compounded of an oscillation in autumn temperatures (at the resonant frequency of the system, 2.4 years) and, secondarily, by an oscillation in wheat prices (wavelength = 5.3 years, twice that of the epidemics).  相似文献

Using data from the 1981, 1991, and 2001 waves of the Panel Study of Income Dynamics and several decennial censuses, we examine how characteristics of metropolitan areas are associated with black and white households’ neighborhood racial composition. Results from hierarchical linear models show that about 20% to 40% of the variation in the percentage of households’ tract population that is non-Hispanic white or non-Hispanic black exists across metropolitan areas. Over time, white households’ exposure to non-Hispanic white neighbors has declined, and their exposure to non-Hispanic black neighbors has increased; the reverse trends are observed for blacks. These trends cannot be attributed to changes in the ecological structure of metropolitan areas. Blacks have fewer white neighbors in large metropolitan areas containing sizable minority populations, and blacks have more white neighbors in metropolitan areas with high government employment. Whites have more black neighbors in metropolitan areas with high levels of government employment and ample new housing; whites have fewer black neighbors in metropolitan areas with a high level of municipal fragmentation. The association between metropolitan-area percentage black and tract percentage black is weaker among whites than among blacks, suggesting that whites are especially motivated to self-segregate in metropolitan areas with large black populations.  相似文献

Large firms face a conflict in managing a portfolio of high-risk projects. When an ongoing project is thought to have a low likelihood of success, project team members take risks to improve its chances of success. However, upper-level managers who allocate resources tend to withhold resources from a project with a low likelihood of success in favor of others in the portfolio that look more promising. Because this paucity of resources influences project team members to avoid risk, the total effect of success likelihood on risk taking is conflicted. The influence on risk taking of a project's terminal value—defined as the value that remains in the firm in the event of project failure—is unequivocally positive, because both senior management resource allocation and project team risk-taking propensity are encouraged by terminal value. Thus, firms can override the ambivalent effect of likelihood of success on project decision making by focusing attention on a project's terminal value.  相似文献

Using a sample of 3,977 youths from the National Longitudinal Survey of Youth (NLSY97), this study examines the unique characteristics of single‐custodial‐father families with adolescents and the effects of single fathers' involvement and parenting on outcomes in emerging adulthood. Findings suggest that single‐custodial‐father families are distinct from single‐mother and 2‐biological‐parent families in terms of sociodemographic characteristics, parenting styles, and involvement. Parenting styles and involvement mediate the differences between single‐father families and 2‐parent families in terms of high school completion and disconnectedness and partially mediate differences for single‐custodial‐father families with a partner. Family and sociodemographic characteristics are also associated with being disconnected for adolescents residing with a cohabiting custodial father.  相似文献

China has been experiencing pronounced changes in its sex ratio, but little research has explored the consequences of these changes for sexual behavior and health. We merge data from the 1999-2000 Chinese Health and Family Life Survey with community-level data from the 1982, 1990, and 2000 Chinese censuses to examine the relationship between the local sex ratio and several dimensions of men's sexual behavior and sexual health. Multilevel logistic regression models show that, when faced with a relative abundance of age-matched women in their community, Chinese men are slightly less likely to have intercourse with commercial sex workers, but are more likely to engage in premarital noncommercial intercourse and to test positive for a sexually transmitted infection. These findings are consistent with hypotheses derived from demographic-opportunity theory, which suggests that an abundance of opposite-sex partners will increase the risk of early, frequent, and multi-partner sex and, through this, sexually transmitted infection risk.  相似文献

In this paper, we consider methods of inference for vector measures of inequality and poverty. These vector measures may consist of several different scalar measures of inequality or poverty in a single dimension, several scalar measures of poverty which use different poverty lines, or several scalar measures of inequality or poverty in different dimensions. Our proposed methods are illustrated with a Monte Carlo simulation and two empirical examples utilizing Canadian household data.  相似文献
