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

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

Prior research has examined race and class bias embedded in media presentations of pregnant drug users; however, this past research is limited in identifying biases because it focuses on single substances—primarily crack cocaine. I build on this work by conducting a comparative analysis of more than 15 years worth of New York Times articles on three drugs (crack cocaine, alcohol, and tobacco) used during pregnancy. These three drugs have varying levels of deleterious effects on fetal development and infant health, as well as varying levels of use by poor and minority women. Because of this variation, I am able to assess whether media coverage of pregnant drug‐using women is proportional to the documented adverse consequences of specific drugs or, rather, whether media coverage is higher and more negative for poor and minority pregnant women regardless of the degree of adverse health consequences associated with the specific drug used. Through this analysis, I demonstrate that the prevalence and framing of news stories about pregnant drug‐using women has little to do with protecting the health of children. Rather, concern for children is a rhetorical tool used to define poor and minority women as bad mothers and blame them for contemporary changes in families.  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

This article seeks to understand the effects of welfare-state spending on infant mortality rates. Infant mortality was chosen for its importance as a social indicator and its putative sensitivity to state action over a short time span. Country fixed-effects models are used to determine that public health spending does have a significant impact in lowering infant mortality rates, net of other factors, such as economic development, and that this effect is cumulative over a five-year time span. A net effect of health spending is also found, even when controlling for the level of spending in the year after which the outcome is measured (to account for spurious effects or reverse causation). State spending effects infant mortality both through social mechanisms and through medical ones. This article also shows that the impact of state spending may vary by the institutional structure of the welfare state. Finally, this study tests for structural breaks in the relationship between health spending and infant mortality and finds none over this time period.  相似文献

The gender gap in support for a female presidential candidate gathered much media attention with Hillary Clinton as a frontrunner for the 2008 democratic presidential nomination. Two common explanations for this gap are that women have more liberal gender role and political attitudes. We contend that another important, and distinct, factor for heightened support among women is a shared social identity. We tested these three explanations across two studies. In Study 1, hierarchical regression analyses revealed that both attitudes toward women and sex independently predict a significant proportion of the variance in willingness to elect a woman for president. In Study 2, hierarchical regression analyses showed that when entered together, attitudes toward female authority and sex independently predict support, but when political attitudes was entered, only sex and political attitudes predicted support for Clinton. Finally, as expected, when primed with their gender identity, women increased their support for Clinton and men decreased their support, and women perceived her more favorably and men less so. In sum, these studies strongly support the arguments that the gender gap in support for female presidential candidates stems in part from women's more liberal gender role and political attitudes, and also from women sharing the same gender social identity as a female candidate for commander in chief .  相似文献

Convergent lines of evidence from adoption, family, geographical, immigrant, molecular genetic, surname, and twin studies of suicide point to genetic contributions to risk factors for suicidal behavior. Related mental health literacy (knowledge and beliefs) of professionals and laypersons may, however, lag behind this research progress. The purpose of this study was to further validate the 22-item Beliefs in the Inheritance of Risk Factors for Suicide Scale (BIRFSS), a novel instrument for assessing individuals' beliefs in the genetics of suicide. Data from a general population sample of 159 Austrian adults showed adequate internal scale consistency. Due to deliberate content heterogeneity, the instrument has a subscale structure, but factor analysis of items extracted a dominant first factor. BIRFSS scores were positively related to overall and specific knowledge on suicide facts (convergent validity), whereas unrelated to the Big Five personality dimensions, locus of control, social desirability, and verbal intelligence (discriminant validity). Demographic correlates of BIRFSS scores included respondents' age and religiosity (both positive ones), but not respondents' sex, educational level, or political orientation.  相似文献

Based in a minority social stress perspective, this study uses propensity score matching techniques to assess the impact of self-reported discrimination on mental health. Using a sample of 14,609 young adults from the National Longitudinal Study of Adolescent to Adult  Health, we explore whether the effects of discrimination vary across status characteristics (e.g., gender, race/ethnicity, sexual orientation, and body mass), including both majority and minority populations. Further we investigate the heterogeneous effects of discrimination across propensity scores, or probabilities of experiencing discrimination. We find that self-reported discrimination increases the average perceived stress score and depressive symptoms score by roughly ½ standard deviation, but is not related to anxiety. Further, our results show that while all groups are negatively affected by discrimination, the magnitude of the impact is largest among groups with the lowest propensity scores.  相似文献

The present study explored the experiences of parents of children with Down syndrome at different phases of the life span. Using a mixed‐method design, the current study included 445 participants who were divided into 4 groups based on the age of the child: (a) parents of children under 5 years of age (early childhood), (b) parents of children between 5 and 11 years of age (middle childhood), (c) parents of children between 12 and 18 years of age (adolescence), and (d) parents of children over the age of 18 (chronological adults). Parents reported higher coping strategy scores during the middle childhood and adolescent years than early childhood or later years (adult children). Qualitative data identified key areas that parents across the 4 groups reported, including acceptance of the diagnosis, having a positive attitude, their child's developmental level, and other internal and external factors that contribute to their attitudes and coping.  相似文献
