This paper examines how full-time or part-time status affects students’ level of satisfaction with their degree programs.
For our analysis, we obtained data from a survey of graduate students. The survey was conducted at a public university in
Spain from 2001 to 2004. The decision to undertake paid employment while studying emerges as one of the key determinants of
student satisfaction. In particular, our findings indicate that students who hold a part-time job while studying are more
likely to express less satisfaction with their college experience. 相似文献

We test whether job insecurity of parents and children affect children’s moving-out decisions. Macroeconomic estimates for
13 European countries over 1983–2004 show that coresidence increases by 1.7 percentage points (PP) following a 10 PP rise
in the share of youths perceiving their job to be insecure and declines by 1.1 PP following the same increment in insecurity
for older workers. Microeconometric evidence for Italy in the mid-1990s shows that the probability of moving out increases
by about half a percentage point for a one-standard-deviation increase in paternal insecurity and by one-third of a percentage
point for a one-standard-deviation decrease in children’s insecurity. 相似文献

We used data from the Birth to Twenty Cohort study to understand children’s receipt of financial support from their fathers in a low income, Black community in urban South Africa. Specifically, we (1) described fathers’ financial support over the life course of children; (2) estimated survival probabilities of receiving support for all children and not receiving support for children who experienced a parental union dissolution; and (3) identified factors that explained variation in the receipt of support after a union dissolution. Results suggest that most children received full or partial support throughout the life course. Furthermore, a high proportion of children received support after a union dissolution with much of the variation driven by pre-dissolution support, father’s education and the presence of extended kin. 相似文献

This paper examines family interactions between mothers and children in single‐parent‐by‐choice (SPBC) families in Spain. The data is part of a larger multi‐sited ethnographic study focused on emergent family structures that examined families formed by women who began their family projects through adoption or assisted reproduction. Single‐mothers‐by‐choice formulate various socialization goals that are tied to the complexities of their non‐conventional family project. These goals are also realized in daily conversation, particularly when families talk about future events in their lives. Our findings expand existing family language socialization research in Western contexts, which has primarily focused on conventional two‐parent families, and invite developing a stronger dialogue between family language socialization research and current debates on changing kinship structures in post‐industrial societies. Este trabajo examina interacciones entre madres e hijos/as en familias de madres solteras por elección (MSPE) en España. Los datos provienen de una investigación etnográfica multi‐lugar más amplia centrada en modelo familiares emergentes que estudió a familias formadas por mujeres solas que han comenzado su proyecto familiar a través de la reproducción asistida o la adopción. La madres solteras por elección formulan varias metas de socialización que están ligadas a las complejidades y demandas de su proyecto familiar no convencional. Estos objetivos también se plasman en conversaciones cotidianas, especialmente cuando las familias hablan sobre eventos futuros en su vidas. Nuestros resultados amplían la investigación sobre socialización lingüística familiar en contextos occidentales, que se ha centrado principalmente en familias bi‐parentales convencionales, e invitan a desarrollar un diálogo más fructífero entre la investigación sobre socialización lingüística familiar y los debates actuales en torno a cambios en los patrones de parentesco en sociedades post‐industriales.

Elementary students survey buildings in an extracurricular community service project to learn social studies and historic preservation. From these experiences students formed values and dispositions by engaging in a constructivist process of creating knowledge by examining their community. They gathered data, transformed it into information, and shared it with the larger community. Because students learned what community means in reality, not just reading about it, they had a different understanding of how they related to the place they called home. Examining these types of questions helped elementary students have significant experiences that helped them to connect community members with the importance of place. The built environment is the context for historic structures. Student engagement with the social studies curriculum allowed them to create investigations with architecture to broaden their understanding of their world. 相似文献

We examine how race affects the employment status of subordinates following a job change by their immediate supervisors. We test whether racial homophily between a subordinate and a supervisor affects the odds of being let go. We also consider whether a racial match between an incoming head coach and assistant affects whether assistants retain their assistant coaching position. Data for these analyses come from a unique data set that explores what happens to 704 NCAA Division I college basketball assistant coaches after the head coach leaves the school. Logistic regression analyses confirm the benefit of working for a white head coach as this decreases the likelihood of being let go, compared to more positive outcomes such as following the coach to a new school, being internally promoted or retained after the head coach's departure. Furthermore, racial homophily with incoming head coaches insulates subordinates from having to search for new employment by increasing the likelihood of assistants being retained. 相似文献

Studies regarding the effectiveness of homework assignments in cognitive‐behavioral treatments have demonstrated mixed results. This study investigated predictors of compliance with homework recommendations and the time‐varying relationship of recommendation completion with treatment response in a brief couples' intervention (N = 108). More satisfied couples and couples with more motivation to change completed more recommendations, whereas couples with children completed fewer. The association between recommendation completion and treatment response varied with the passage of time, with the strongest effect observed 6 months after the intervention, but no discernible differences at 1 year postintervention. Couples that completed more recommendations experienced more rapid treatment gains, but even those couples doing substantially fewer recommendations ultimately realized equivalent treatment effects, although they progressed more slowly. Implications are discussed. 相似文献

In this analysis, I examine the effects of community-level volunteering on an individual’s choices regarding time – whether to work and whether to volunteer. In order to better explain the decision to volunteer, a classic pure public goods structure is contrasted with a less restrictive impure public goods model that admits other possible private motivations. The results of this study undermine the neoclassical notion that volunteering can be understood solely as a pure public good that is provided less when others are seen to be contributing. In fact, individuals are found to be more, not less, likely to volunteer when others in their communities do so. An innovative instrumental variables strategy is used to account for reflection bias and the possible endogeneity caused by selective sorting of individuals into neighborhoods, which allows for a causal interpretation of these results. Employment regressions provide preliminary evidence that average volunteering relates, to some extent, with the decision of whether to participate in the labor force. Variations in the effect of average volunteering across age and gender are also explored. The present work is unique by virtue of its use of a large and representative dataset, along with rigorous statistical testing. I use United States Census 2000 Summary File 3 and Current Population Survey (CPS) 2004–2007 September Supplement file data and control for various individual and community-level characteristics. 相似文献

This study examined gender, age, and task differences in positive touch and physical proximity during mother–child and father–child conversations. Sixty-five Spanish mothers and fathers and their 4- (M = 53.50 months, SD = 3.54) and 6-year-old (M = 77.07 months, SD = 3.94) children participated in this study. Positive touch was examined during a play-related storytelling task and a reminiscence task (conversation about past emotions). Fathers touched their children positively more frequently during the play-related storytelling task than did mothers. Both mothers and fathers were in closer proximity to their 6-year-olds than their 4-year-olds. Mothers and fathers touched their children positively more frequently when reminiscing than when playing. Finally, 6-year-olds remained closer to their parents than did 4-year-olds. Implications of these findings for future research on children’s socioemotional development are discussed. 相似文献

This study is an assessment of different components of attachment for a sample of Romanian adoptees and their parents, both who participated in the project (n = 63). Results suggest that various aspects of the parent–child relationship in early adolescence is quite positive from both the adoptee and adoptive parent perspective. However, almost half (46 %) of the adoptees were assessed as having insecure attachment. There are differences between all components of parental attachment and adoptee attachment security. Also, insecure attachment is more likely to occur with less optimal parenting style. Implications for social work practice and research are discussed. 相似文献
