Although there has been increasing attention to the importance of fathers and their relationships with their children, few studies have examined young parenthood and its consequences for fathers’ life chances. In recent years, this has begun to change, and research is examining, to a far greater extent, the experiences of young fathers. Using data from a cohort of British men born in 1970, this paper uses a propensity score–matching technique to compare the well‐being of 344 men who reported becoming fathers before the age of 22 with men from similar backgrounds who did not. The findings suggest that selection into young fatherhood is substantial but, for some outcomes, significant differences remain. 相似文献

This article analyzes immigrant incorporation and transnational participation as gendered experiences. The results indicate that the incorporation of immigrants is a complex process affected negatively by class and racial exclusion and positively by their knowledge of U. S. society. The analysis also indicates that incorporation and transnational participation are concurrent and intertwined processes. Our results show that gender matters in the analysis of immigrant incorporation. The experiences of immigrant men and women share a lot in common as they confront similar challenges, but are also affected differently by the most relevant factors in the process of incorporation and transnational participation. 相似文献

This study examines the mediating effect of international alliances for the relationship between TMT (top management team) job‐related diversity (educational, functional background, outside industry experience and international exposure) and firm internationalization. We argue that firms with greater TMT diversity will use more international alliances, resulting in higher firm internationalization. Based on a sample of 226 US firms during the period 1988–1994, we find that international alliances partially mediate the relationship between TMT international exposure diversity and firm internationalization. However, we do not find international alliances to mediate the relationships between other forms of TMT diversity and firm internationalization. We discuss implications and directions for future research. 相似文献

Summary. We consider the construction of perfect samplers for posterior distributions associated with mixtures of exponential families and conjugate priors, starting with a perfect slice sampler in the spirit of Mira and co-workers. The methods rely on a marginalization akin to Rao–Blackwellization and illustrate the duality principle of Diebolt and Robert. A first approximation embeds the finite support distribution on the latent variables within a continuous support distribution that is easier to simulate by slice sampling, but we later demonstrate that the approximation can be very poor. We conclude by showing that an alternative perfect sampler based on a single backward chain can be constructed. This alternative can handle much larger sample sizes than the slice sampler first proposed. 相似文献

Maternal Emotional Styles and Child Social Adjustment: Assessment, Correlates, Outcomes and Goodness of Fit in Early Childhood 总被引:3,自引:0,他引:3
The goals of the present research were to develop a modified version of an existing self‐assessment questionnaire designed to measure parents’ emotional style and to examine how the aspects of child regulation may moderate the relation between the emotional styles and social outcomes in childhood. Participants in Study 1 were 140 mothers and children (73 males, 67 females, Mage=56.0 months). The mothers completed the Maternal Emotional Styles Questionnaire (MESQ) to assess maternal emotional styles, and the Child Behavior Vignettes to assess parental goals across two scenarios. Participants in Study 2 were 50 mothers who were interviewed regarding their emotional styles using the Meta‐emotion Interview, and who also completed the MESQ. In Study 3, 100 mothers and children (41 males, 59 females, M=58.0 months) participated. The mothers completed the MESQ and the Child Behavior Questionnaire to assess the children's emotion and behavior regulation. Teachers completed the Child Behavior Scale to measure the indices of preschool adjustment. Results from Studies 1 and 2 indicated a two‐factor scale for the MESQ, with good psychometric properties (including stability, convergent validity, and construct validity). Results from Study 3 indicated different patterns of associations between maternal emotional styles, and child adjustment for well‐regulated versus dysregulated children. 相似文献

The Catholic Church reacted to the Protestant Reformation by taking on the defensive posture of an incumbent-firm monopoly fighting to survive in the face of new competition. Contemporary firms typically respond to rival entry by rewriting their corporate charter. So did the medieval Catholic Church. But the Council of Trent failed as a reorganization plan because to keep economic rents flowing as before, it left intact the distribution of powers and property rights among the governing body of pope and cardinals—thus demonstrating that entrenched economic interests are powerful inducements to behavior, even in spiritual institutions. 相似文献

Abstract. We review and extend some statistical tools that have proved useful for analysing functional data. Functional data analysis primarily is designed for the analysis of random trajectories and infinite‐dimensional data, and there exists a need for the development of adequate statistical estimation and inference techniques. While this field is in flux, some methods have proven useful. These include warping methods, functional principal component analysis, and conditioning under Gaussian assumptions for the case of sparse data. The latter is a recent development that may provide a bridge between functional and more classical longitudinal data analysis. Besides presenting a brief review of functional principal components and functional regression, we develop some concepts for estimating functional principal component scores in the sparse situation. An extension of the so‐called generalized functional linear model to the case of sparse longitudinal predictors is proposed. This extension includes functional binary regression models for longitudinal data and is illustrated with data on primary biliary cirrhosis. 相似文献

Across a variety of clinical settings, repeated measurements on an individual, obtained under identical circumstances, often differ from one another. This implies the measurements lack perfect reproducibility. Topics related to reproducibility of clinical measurements are introduced in this paper. In this first of two parts, continuous outcomes are addressed. The intraclass correlation coefficient, ρ, has been the traditional coefficient of reproducibility for continuous outcomes. The importance of ρ regarding observations on an individual, and observations among populations, is outlined. Estimation and inferential procedures for ρ are reviewed and worked examples are provided. Copyright © 2004 John Wiley & Sons, Ltd. 相似文献

We investigated the impact of relative marital power on 72 newlywed couples’ endocrinological responses to marital conflict. Marital power was determined by comparing spouses’ reports of dependent love for one another. Less powerful spouses displayed elevated adrenocorticotropic hormone (ACTH) responses to a conflict discussion. Shared power appeared to have a beneficial effect on wives’ but not husbands’ ACTH responses. Spouses’ cortisol levels declined over time, except for wives who were less powerful and for husbands who shared power with their wives. Conflict behaviors did not differ as a function of this marital power index. These data suggest that relative levels of general emotional power in relationships may play an important role in spouses’ physiological responses to marital conflict. 相似文献

Evidence abounds that college sports are rife with corruption. Over a century of reform efforts have failed to bring about lasting structural and cultural changes. Drawing on interview, participant observation, and archival data, the present study examines the diagnostic and prognostic framing of the contemporary college sports reform movement. The faculty-driven wing of the social movement has identified several problems with intercollegiate athletics including (1) commercialization; (2) university involvement in the entertainment industry; (3) damage to the integrity of higher education; (4) exploitation of athletes; and (5) harm to nonathletes. Reform proposals and strategies of The Drake Group and the Coalition on Intercollegiate Athletics are summarized and compared. 相似文献
