Maternal education differences in children's academic skills have been strongly linked to parental investment behaviors. This study extended this line of research to investigate whether these same maternal education patterns in parenting are observed among a set of parenting behaviors that are linked to young children's health. Drawing on data from the Early Childhood Longitudinal Study, Birth Cohort (n = 5,000) and longitudinal models incorporating random effects, the authors found that higher levels of maternal education were associated with more advantageous health investment behaviors at each phase of early development (9 months, 2 years, 4 years, 5 years). Moreover, these disparities were typically largest at the developmental stage when it was potentially most sensitive for children's long‐term health and development. These findings provide further evidence of a developmental gradient associated with mothers' education and new insight into the salience of mothers' education for the short‐ and long‐term health and well‐being of their children. 相似文献

The authors examine factors associated with the advancement or dissolution of newly formed sexual relationships. Data from the 2006–2010 National Survey of Family Growth (NSFG) was used to examine women and men aged 18–39 (n = 2,774) whose most recent sexual relationship began within the 12 months before their interview. Results indicate that newly formed sexual relationships are often transitory. By 12 months, only 23% of respondents remained in nonresidential sexual relationships, another 27% were cohabiting with that partner, and half had ended their relationships. Sexual relationships formed before age 25 are significantly more likely to break up than to transition into cohabitation. Indicators of social class disadvantage, such as living with a stepparent, expedited cohabitation, whereas measures of advantage, such as having a college‐educated mother, deterred transitions into shared living. Racial differences also emerge: Blacks were less likely than Whites to transition rapidly into shared living. 相似文献

In this paper, we discuss the bivariate Birnbaum-Saunders accelerated lifetime model, in which we have modeled the dependence structure of bivariate survival data through the use of frailty models. Specifically, we propose the bivariate model Birnbaum-Saunders with the following frailty distributions: gamma, positive stable and logarithmic series. We present a study of inference and diagnostic analysis for the proposed model, more concisely, are proposed a diagnostic analysis based in local influence and residual analysis to assess the fit model, as well as, to detect influential observations. In this regard, we derived the normal curvatures of local influence under different perturbation schemes and we performed some simulation studies for assessing the potential of residuals to detect misspecification in the systematic component, the presence in the stochastic component of the model and to detect outliers. Finally, we apply the methodology studied to real data set from recurrence in times of infections of 38 kidney patients using a portable dialysis machine, we analyzed these data considering independence within the pairs and using the bivariate Birnbaum-Saunders accelerated lifetime model, so that we could make a comparison and verify the importance of modeling dependence within the times of infection associated with the same patient. 相似文献

Identity theory distinguishes three bases of identity—role, group, and person—but studies have typically focused on one identity at a time. The interrelationship among the multiple bases of identity remains understudied. This study examines the multiple bases of identity individuals engage on their way to becoming ministry students. The results reveal the advantage of examining the multiple bases of identity as subcultural processes, the utility of qualitative research for expanding the empirical scope of identity theory, and the possibility of employing structural symbolic interactionist concepts within a processual symbolic interactionist agenda. 相似文献

Peer interaction is an important component of children's social repertoires that is associated with a variety of developmental outcomes and life skills. The present study provides an in‐depth study of early dyadic peer behaviors during the infancy period, during which social competence with peers is first being developed. Results from variable‐centered analyses highlight the effectiveness of behaviors, such as offering objects to peers, and point to the importance of the social context set by a peer's prior social behavior and processes for eliciting peer responses. Findings from person‐centered analyses reveal marked individual differences in the processes through which infants are successful in eliciting responses from their peers, illustrating the presence of multiple pathways to achieving social competence with peers. 相似文献

This study used critical discourse analysis (CDA) to identify and unpick some of the ideas, beliefs, and attitudes encoded in newspaper texts without being explicitly stated. It uses a quantitative-qualitative approach to content analysis to compare articles published in the Chinese government-owned, English-language newspaper the China Daily in 1998 (n = 50) and 2010 (n = 50). The analysis focused on two things: the people considered by China Daily journalists to be important/interesting enough to be quoted and (through an analysis of Halliday's verbal processes) how these people's words are presented. The aim was to demonstrate the effectiveness of the approach advocated and to see whether such an approach can help answer how much the media in China has changed in response to changing times. 相似文献

AbstractEvery day, managers work to sustain the organizations wherein they work. In this article, the authors examine certain systemic boundary processes that are intrinsic to organizations and their sustainability. For readers of this journal, whose name points to the inherent connection between organizations and society, the authors present an argument that organizational boundary processes and their influence on organizational sustainability are important considerations for those of us interested in a viable future for our society. The importance of these processes for managers also is indicated. 相似文献

In the present paper, we introduce and study a class of distributions that has the linear mean residual quantile function. Various distributional properties and reliability characteristics of the class are studied. Some characterizations of the class of distributions are presented. We then present generalizations of this class of distributions using the relationship between various quantile based reliability measures. The method of L-moments is employed to estimate parameters of the class of distributions. Finally, we apply the proposed class of distributions to a real data set. 相似文献
