Although the government no longer explicitly establishes boundaries of whiteness, it continues to play a central role in shaping symbolic boundaries between immigrants and nonimmigrants through immigration lawmaking. However, the salience of these boundaries may depend on how the media disseminate them to the public. In this study, we investigate media framing of immigration lawmaking using an original data set of news coverage of six of the most widely recognized exclusionary immigration bills and laws at different levels of government. Two patterns emerged from an iterative frame analysis. First, in their coverage of frames critical of these bills and laws, outlets devoted more attention to the effects of exclusionary legislation for nonimmigrants. Second, in their coverage of frames supportive of the restrictive legislation, outlets provided more space to those who openly associated immigrants with criminality and terrorism. Regardless of outlets’ seemingly neutral stance toward restrictive legislation, their disparate coverage of exclusionary lawmaking demonstrates apathy and antipathy toward immigrants, which has repercussions for the maintenance of inequality.  相似文献

在实现经济现代化方面,起至关重要作用的两大决定性因素就是市场和企业组织。但是,市场和企业的正常运作却离不开公共行政的相对独立及其作用。实际上,现代市场、现代企业组织、相对独立于政治的公共行政这三者之间,不仅存在着产生和发展上的共时性,而且在相互关系上也存在着内在的和必然的逻辑联系,从而推动了现代经济的迅速发展。这种内在联系来自三者的共同基础,这就是合理性和合法性。因此,合理性和合法性是现代化的逻辑基础,也可以把合理性和合法性看成是衡量现代化程度的两项主要尺度。  相似文献

Because social media provide users with the possibility of an easy way to communicate with celebrities in society, it has become a more common practice to follow celebrities through social media. However, there exists few studies that examine how people’s individual characteristics are related to their celebrity-following behavior. In this regard, the current study examines whether celebrity followers’ loneliness is associated with the following behavior of their favorite celebrity. Data were collected through an online survey (N = 210). Primary findings suggest that celebrity followers’ loneliness is positively related to frequent visits of their favorite celebrity’s social media, greater social-interpersonal motive for following the celebrity, and greater enjoyment of learning about personal life stories of the celebrity. Social presence is found to be a significant moderator that can intensify more favorable parasocial relationship perceptions with the celebrity.  相似文献

ABSTRACT

Guided by the Person-Environment Fit perspective, we investigated the extent to which personal and environmental factors influence depression among community-dwelling adults. The data came from the special section about community-based service utilization in the 2012 Health and Retirement Study (N=1,710). Although community-based service was not significantly associated with depression after controlling for covariates, respondents with functional limitations and living alone were less likely to be depressed when using community-based services. This study demonstrates the different associations between community-based services and depression depending on personal needs. It discusses the importance of community-based services for aging-in-place policy, particularly among vulnerable populations.  相似文献

Though the concept of blight clarifies housing and neighborhood changes in rural and small towns experiencing disinvestment and decline, the term is rarely examined outside of urban discourse. This study explores the extent of rural blight and its relationship to community characteristics using survey results from elected officials and staff members of small towns in one southeastern state. We examine the historical background of blight, including its connections to urban renewal, racial bias and stereotyping, and the broken windows theory. Among the small towns in the study, economic blight, particularly dilapidated housing, was prevalent. Social blight, which includes behaviors that are thought to be threatening or criminal in nature, was less common but correlated moderately with economic forms of blight. While social disorganization and collective efficacy theories link a range of demographic characteristics to physical and social disorder, our findings pointed only to a significant relationship between communities with a higher portion of the population who are black and multiple forms of extensive blight. More research is needed to understand the relationship, both observed and perceived, between economic and social blight in rural small towns and how these issues may be remediated through local collective action.  相似文献

This paper explores how children's perceptions of their agency, as something that is closely associated with its exercise, appear in relation to social structural factors, especially their socioeconomic positions, as they age. Using data from 862 10–18 years old in South Korea, we examine how children's expressed optimism about their ability to achieve their occupational choices can conceal the impact of structural factors on their ‘choices’ and dispositions for (non‐)action over time. Based on the findings, we argue for a more careful interpretation of children's sense of agency that recognises its propensity to continuously adjust in contexts of structural inequality.  相似文献

Twenty-four-hour recall data from the Continuing Survey of Food Intake by Individuals (CSFII) are frequently used to estimate dietary exposure for risk assessment. Food frequency questionnaires are traditional instruments of epidemiological research; however, their application in dietary exposure and risk assessment has been limited. This article presents a probabilistic method of bridging the National Health and Nutrition Examination Survey (NHANES) food frequency and the CSFII data to estimate longitudinal (usual) intake, using a case study of seafood mercury exposures for two population subgroups (females 16 to 49 years and children 1 to 5 years). Two hundred forty-nine CSFII food codes were mapped into 28 NHANES fish/shellfish categories. FDA and state/local seafood mercury data were used. A uniform distribution with minimum and maximum blood-diet ratios of 0.66 to 1.07 was assumed. A probabilistic assessment was conducted to estimate distributions of individual 30-day average daily fish/shellfish intakes, methyl mercury exposure, and blood levels. The upper percentile estimates of fish and shellfish intakes based on the 30-day daily averages were lower than those based on two- and three-day daily averages. These results support previous findings that distributions of "usual" intakes based on a small number of consumption days provide overestimates in the upper percentiles. About 10% of the females (16 to 49 years) and children (1 to 5 years) may be exposed to mercury levels above the EPA's RfD. The predicted 75th and 90th percentile blood mercury levels for the females in the 16-to-49-year group were similar to those reported by NHANES. The predicted 90th percentile blood mercury levels for children in the 1-to-5-year subgroup was similar to NHANES and the 75th percentile estimates were slightly above the NHANES.  相似文献
