We used data from the National Longitudinal Study of Adolescent Health (N = 7,686) to determine whether racial and ethnic differences in socioeconomic stress and social protection explained group differences in the association between family structure instability and three risk behaviors for White, Black, and Mexican American adolescents: delinquent behavior, age at first nonmarital sex, and age at first nonmarital birth. The positive association between mothers' union transitions and each outcome for White adolescents was attenuated by social protection. The association of instability with age at first sex and first nonmarital birth was weaker for Black adolescents but not for Mexican American adolescents. The weaker association was explained by Black adolescents' more frequent exposure to socioeconomic stress in the context of union instability. 相似文献

Understanding residential mobility in early childhood is important for contextualizing family, school, and neighborhood influences on child well-being. We examined the consequences of residential mobility for socioemotional and cognitive kindergarten readiness using the Early Childhood Longitudinal Study-Birth Cohort, a nationally representative longitudinal survey that followed U.S. children born in 2001 from infancy to kindergarten. We described individual, household, and neighborhood characteristics associated with residential mobility for children aged 0–5. Our residential mobility indicators examined frequency of moves, nonlinearities in move frequency, quality of moves, comparisons between moving houses and moving neighborhoods, and heterogeneity in the consequences of residential mobility. Nearly three-quarters of children moved by kindergarten start. Mobility did not predict cognitive scores. More moves, particularly at relatively high frequencies, predicted lower kindergarten behavior scores. Moves from socioeconomically advantaged to disadvantaged neighborhoods were especially problematic, whereas moves within a ZIP code were not. The implications of moves were similar across socioeconomic status. The behavior findings largely support an instability perspective that highlights potential disruptions from frequent or problematic moves. Our study contributes to literature emphasizing the importance of contextualizing residential mobility. The high prevalence and distinct implications of early childhood moves support the need for further research. 相似文献

Problem
Supplementation of breastfed babies is common during the hospital stay.Background
The Baby Friendly Hospital Initiative (BFHI) optimises practices to support exclusive breastfeeding, yet supplementation is still prevalent.Objective
To determine predictors for supplementation in a cohort of breastfed babies in a Baby-Friendly hospital.Methods
Electronic hospital records of 1530 healthy term or near term singleton infants and their mothers were examined retrospectively and analysed to identify factors associated with in-hospital supplementation using Poisson regression (unadjusted and adjusted).Findings
Fifteen percent of breastfed infants were supplemented during their hospital stay. Analysis by multivariable Poisson regression found that supplementation was independently associated with overweight (reference normal weight) (aRR [adjusted relative risk] = 1.46; 95% CI: 1.11–1.93); primiparity (aRR = 1.40; 95% CI: 1.09–1.80); early term gestation (37–376 weeks, aRR = 2.79; 95% CI: 1.88–4.15; 38–386 weeks, aRR = 2.03, 95%CI: 1.46–2.82); birthweight less than 2500 grams (reference 3000–3499 grams) (aRR = 3.60; 95% CI: 2.32–5.60) and use of postpartum uterotonic (aRR = 2.47; 95% CI: 1.09–5.55). Greater than 65 minutes of skin-to-skin contact at birth reduced the risk of supplementation (aRR = 0.66; 95% CI; 0.48–0.92).Conclusion
These identified predictors for supplementation, can inform the development of interventions for mother-infant pairs antenatally or in the early postpartum period around increased breastfeeding education and support to reduce supplementation. It may also be possible to reduce supplementation through judicious use of postpartum uterotonics and facilitation of mother-infant skin-to-skin contact at birth for greater than one hour duration. 相似文献34.

Banks in Germany are experiencing a profound legitimacy crisis. In the wake of financial and economic crises, failures, and bailouts, as well as new oversight and stricter regulations, banks have lost the reputation and trust they once had. The present article uses an analysis of interpretative patterns to examine how banks seek to legitimize themselves in times of crisis, with reference to sustainability as a guiding principle of society. Following the concept of social legitimacy by new institutionalism in sociology, and based on discursive interviews with 18 representatives of German banks, we reconstructed three interpretative patterns: a) the differentiation from “bad” banks, which abandons profit-maximizing business models and promotes the moral superiority of sustainable banking, b) responsibility for society, which promotes the role and responsibility of banks as socially relevant actors that spur social change, and c) “right” return, whereby banks seek an appropriate relationship between their value orientation and a return on investments. Although a return on investment is economically necessary and confers legitimacy, it may not be understood as an end in itself. Banks discredited during the crisis can refocus on a banking model which promises social legitimacy by referring to sustainability. 相似文献

Vocal plasticity may allow birds to reduce masking effects of noise pollution arising from urbanization. Mountain chickadees (Poecile gambeli) use both songs and calls during the dawn chorus, which vary in masking susceptibility. Thus, increasing song or call frequency, or switching between vocalization types are all potential mechanisms to reduce masking during fluctuating noise conditions. Further, prior experience with noise pollution may be a necessary precursor to allow birds to alter signals in response to sudden noisy conditions. To determine how mountain chickadee songs, calls, and chorus composition are affected by noise, we recorded 55 males across gradients of local ambient noise and habitat urbanization in three cities in British Columbia, Canada. Of these individuals, 31 were also exposed to 5-min experimental noise treatments. Habitat urbanization was quantified through a continuous index reflecting properties of urbanized areas. Only song frequency increased with local ambient noise, and this effect varied regionally. In response to experimental noise exposure, males increased the frequency of their calls (but not of their songs), and varied their use of songs vs. calls. Interestingly, this response was dependent on local ambient noise levels: males in noisy areas shifted to using relatively more songs, whereas males in quiet areas shifted to using relatively more calls. These findings may suggest that although mountain chickadees are capable of adjusting their vocalizations, choosing a response which can lead to masking release may require prior exposure to high levels of ambient noise. 相似文献

Urbanization creates new habitats with novel benefits and challenges not found in natural systems. How a species fares in urban habitats is largely dependent on its life history, yet predicting the response of individual species to urbanization remains a challenge. While some species thrive in urban areas, others do poorly or are not present at all. Mountain chickadees (Poecile gambeli) are year-round residents of montane regions of western North America. Commonly found in higher-elevation coniferous forests, these birds can also be found in urban areas where they will regularly visit bird feeders and nest in nest boxes. We monitored mountain chickadees nesting along a habitat gradient, from natural habitat to suburban areas, to determine if the degree of urbanization was associated with: clutch size and success; nestling growth rates; or variation in parental size and age. Females nesting in urbanized areas initiated clutches earlier in the breeding season than those in natural areas, but neither fledging success nor the rate of nestling mass-change differed between habitats. Nestling feather growth-rate increased with later first egg dates in both habitats, and the magnitude of this increase was greatest in urban habitats. We found no difference in the proportion of first-time breeders versus experienced breeders between habitat types, nor any differences in male or female mass or size. Our results indicate no detriment to nesting in urban habitats, suggesting mountain chickadees are able to adapt to moderate urbanization much like other members of the Paridae family. 相似文献

This research explores with the help of pretest-posttest-design with two repeated measures, control group and 19 clients, whether a Life Coaching can change a life dissatisfaction. As a result, dissatisfaction decreased in 81% of the clients or terminate completely. Stressors were reduced by 100% (T(11) = 4; p < 0.005), strains were reduced by 88%. A significant decline of the emotional-cognitive strains by 89% (T(13) = 0; p < 0.005) was noticed. The stress load all over was significantly lower (T(13) = 20; p < 0.05). It exists a within-subjects effect between intervention and one of the subscales, F(1.24) = 5.776, p = 0.024. 相似文献

Not making the transition to college: School, work, and opportunities in the lives of American youth 总被引:1,自引:0,他引:1
Unlike traditional research on educational stratification that focuses on the pursuit of higher education, our study examines why young adults do not make the transition to college, using a nationally representative sample of college non-enrollees (N = 2640). In applying latent class analysis techniques, we identified multiple types of students who do not pursue college. One group of non-enrollees (27.6%) reports forgoing college because the economic barriers are too high - either because of college affordability or family financial responsibility. These youth had both low math test scores and low family income, and thus closely align with regression-based analyses on college enrollment that emphasize academic and economic constraints as the central barriers to educational progress. However, we also identified a second, often overlooked group of youth who had the academic preparation and family income support to enroll in higher education, but decided to forgo college because they preferred to work and to make money (18.3%). The heterogeneous motives of these youth suggest that postsecondary decisions are not always guided by academic and economic barriers, but sometimes driven by previous work experience and perceptions of local opportunities for school and work. 相似文献

Most research studies on return migration analyse remigration and reintegration as individual projects, without considering the interconnectedness of remigrants with their family members. This article addresses this research gap and seeks to add to our understanding of the role which the family plays in shaping reintegration outcomes through a qualitative analysis of the experiences of highly skilled Austrians who returned, with their co- or inter-ethnic family members, in the last 10 years. Results show that the relationship between family and reintegration is complex. Core family members may act both as constraints and as enablers of readjustment. Partners and children ease reintegration by providing enthusiasm, motivation and emotional support. At the same time, family members may also complicate the reintegration process by increasing the amount of administrative work to be done in order to re-organise family life or by triggering feelings of alienation, when family members face (re)-integration challenges. The reintegration process was also found to have a significant impact on highly skilled returnees’ family life. The problem-solving strategies which returnees develop during their process of reintegration either impede the formation of new families, impact on the structure of existing families or change the division of family work in the household. 相似文献

Past research has largely ignored the influence of material resources on teenage parents' life outcomes. A lack of resources such as housing, child care, and financial support is hypothesized to explain the negative effect of teenage parenthood on educational attainment. Regression analyses use nationally representative data from the 1988 - 2000 National Education Longitudinal Study (N = 8,432, n = 356 teenage parents). Results support the hypothesis completely for the teenage fathers in the sample and partially for mothers: Resources substantially diminish the educational penalty teenage parents paid by age 26. Gender influences which types of resources are protective, providing policy implications. Help with child care is critical for teenage mothers, whereas housing and financial resources may be important for men. 相似文献
