The purpose of this study was to examine the influence of parent–adolescent ethnic identity disparities on the psychosocial adjustment of an ethnically diverse sample (n = 174, female = 96) of adolescents (M = 16.05, SD = 1.30). Findings from this investigation suggest gender differences in links between parent and adolescent acculturation disparities and psychosocial maladjustment. Whereas parent–child conflict regarding affiliating with the dominant group was associated with higher levels of depression and social stress for females, this was not the case for males. Implications for social workers providing services to youth and families struggling to acculturate are discussed. 相似文献

To capture both the volatility evolution and the periodicity feature in the autocorrelation structure exhibited by many nonlinear time series, a Periodic AutoRegressive Stochastic Volatility (PAR-SV ) model is proposed. Some probabilistic properties, namely the strict and second-order periodic stationarity, are provided. Furthermore, conditions for the existence of higher-order moments are established. The autocovariance structure of the squares and higher order powers of the PAR-SV process is studied. Its dynamic properties are shown to be consistent with financial time series empirical findings. Ways in which the model may be estimated are discussed. Finally, a simulation study of the performance of the proposed estimation methods is provided and the PAR-SV is applied to model the spot rates of the euro and US dollar both against the Algerian dinar. The empirical analysis shows that the proposed PAR-SV model can be considered as a viable alternative to the periodic generalized autoregressive conditionally heteroscedastic (PGARCH) model. 相似文献

The present study examined the relationships between dissociative experiences, sensation seeking scores, and gambling behavior. On the basis of the frequency of their gambling behavior and responses to the Gamblers Anonymous Twenty Questions, subjects were designated as either problem gamblers (N=30) or social gamblers (N=30).Those designated as problem gamblers responded yes to an average of 12.17 questions on the Gamblers Anonymous Twenty Questions as compared to the social gamblers who averaged 1.90 yes responses. Responses on the Twenty Questions correlated strongly with the frequency of gambling behavior and dissociative experiences. Problem gamblers reported a significantly greater number of dissociative experiences than social gamblers (p<.01). Problem gamblers scored significantly higher than social gamblers on the Total Sensation Seeking Scale, and the Boredom Susceptibility, Experience Seeking, and Disinhibition subscales. Clinical implications and recommendations for future research are discussed. 相似文献

This paper provides an overview of the most significant public policy initiatives that apply to known sexual offenders who live in the community. It is argued that while registration schemes, community notification, and offender residency restrictions have become a prominent feature of contemporary sex offender policy, the evidence base supporting their implementation is, at best, limited. There is a need to develop policies which are more tailored to the needs of individual offenders and which are explicitly designed to manage risk. Policies which mandate and facilitate interagency and partnership working represent one way in which individualised and research‐informed approaches can be developed. It is suggested that the implementation of this type of approach may ultimately lead to more effective community responses to preventing sexual reoffending than those which rely solely on monitoring and supervision. 相似文献

In the German labor market former labor immigrants and their descendents still occupy lower positions. In contrast to the early phase of in-migration nowadays most of the obvious structural reasons for ethnic stratification have vanished. Therefore, remaining inequalities could either be due to processes of discrimination or may result from immigrants’ permanent under-investment in human capital. In this contribution we present theoretical arguments and empirical results why the latter mechanism seems to be more important for the situation in the German labor market. Using data of the micro-census 1996 we analyze, whether labor market positions of immigrants are still lower controlling for generation and education. The findings are rather clear-cut: nearly all labor market disadvantages of the second generation can be traced back to educational differences. 相似文献

The paper examined the conditions that allow alternative logics a long standing coexistence, when no one logic predominates in the supplementary health field in Brazil. It contributes to the literature bringing the analysis of the coexistence over several decades of the following competitive logics - professional, public, market, regulatory, and social protection logic, in an institutional order level, while medical groups, insurance companies, and cooperatives established alternative health provision logics in the market level. The state’s incapacity or unwillingness to alienate the private sector is the main reason for the emergence of the various market medical providers with their distinct forms of service delivery. 相似文献

What are the determinants of the subjective experience of conflict between work and family roles among dual-earner couples in Europe? Taking a demands-and-resources approach, this study investigates the individual and macro-level factors that generate perceptions of negative spill-over from work to family. Comparative survey data for 23 countries come from Round 2 of the European Social Survey. The empirical results support theoretical arguments for a conceptual distinction between time- and strain-based work-family conflicts. The findings also reveal important sex differences in the ways that perceptions of conflict are generated. Moreover, the results from multilevel analyses suggest that the experience of work-family conflict among dual-earner couples is only weakly moderated by institutional or cultural effects. 相似文献

A popular model for competing risks postulates the existence of a latent unobserved failure time for each risk. Assuming that
these underlying failure times are independent is attractive since it allows standard statistical tools for right-censored
lifetime data to be used in the analysis. This paper proposes simple independence score tests for the validity of this assumption
when the individual risks are modeled using semiparametric proportional hazards regressions. It assumes that covariates are
available, making the model identifiable. The score tests are derived for alternatives that specify that copulas are responsible
for a possible dependency between the competing risks. The test statistics are constructed by adding to the partial likelihoods
for the individual risks an explanatory variable for the dependency between the risks. A variance estimator is derived by
writing the score function and the Fisher information matrix for the marginal models as stochastic integrals. Pitman efficiencies
are used to compare test statistics. A simulation study and a numerical example illustrate the methodology proposed in this
paper. 相似文献
