A community structure analysis compared community characteristics and nationwide coverage of immigration reform in newspapers in 21 major U.S. cities, sampling all 250+ word articles April 23, 2010 to November 12, 2013. The resulting 262 articles were coded for “prominence” and “direction” (“favorable,” “unfavorable,” or “balanced/neutral” coverage), then combined into each newspaper's composite “Media Vector” (range = .632 to ?.4800). Nineteen of 21 newspapers showed favorable coverage of immigration reform. Pearson correlations yielded 4 significant results, the most powerful of which supported immigration reform. The “vulnerability” hypothesis (media “mirror” the interests of marginal/disadvantaged groups) was essentially confirmed. Higher percentages below the poverty line (r = .607, p = .003) and higher crime rates (r = .490, p = .017) correlated with more favorable coverage of immigration reform. By contrast, higher percentages of women in the workforce (r = ?.543, p = .008) and higher proportions of hate crimes (r = ?.403, p = .048) were linked with less favorable coverage. Regression analysis yielded the percentage living below the poverty line accounting for 37.2% of the variance, and proportion of hate crimes yielded an additional 19.1% of the variance. The Midwest had by far the most favorable coverage of immigration reform, more than any other region. 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

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

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

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

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

Multimedia technology has the capacity to provide students with an interactive approach to problem based learning and to bridge the gap between theoretical knowledge and clinical practice. The present paper describes the design and development of the program ErgoROM, a CD which presents a case study to assist occupational therapy students in their studies of office ergonomics. A pilot study showed that overall, 91% of respondents rated the ErgoROM as either "Excellent" or "Very Good". Additionally they reported that ErgoROM had a positive impact on active learning and critical thinking. 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
