This study focuses on the ‘self-personalization’ of campaign politics, marked by candidates highlighting their personal lives over their policy positions. The rise of social media may be accelerating this shift. Applying Strategic Stereotype Theory [Fridkin, K. L., &; Kenney, P. J. (2014). The changing face of representation: The gender of U.S. senators and constituent communications. Ann Arbor: University of Michigan Press.], which holds that women politicians try to deactivate stereotypes that associate men with agentic leadership traits while capitalizing on stereotypes that associate them with warmth, we assess what role gender plays in candidate self-personalization on social media. A large-scale computerized content analysis of social media posts by gubernatorial candidates in 2014 suggests that male candidates may see more and female candidates see less strategic benefits in personalizing, but this effect does not persist in the face of electoral contextual variables like competitiveness. We also find qualitative differences in the ways male versus female candidates personalize through social media. 相似文献

The impact of the social environment on human health and development is a common theme among demographers and population dynamics researchers. Less clear are the paths and mechanisms through which the social environment ‘gets under the skin.’ This special issue of Population Research and Policy Review presents five papers that address current scientific thinking on these paths and mechanisms. 相似文献

Employment protection systems are widely believed to generate distortions in firms' hiring and firing decisions. However, much less is known about the impact of these regulations on workers' behavior. In this paper we provide evidence on the latter question using data from a large Italian bank. Our analysis is based on weekly observations for 545 men and 313 females hired as white‐collar workers between January 1993 and February 1995. These workers begin to be protected against firing only after the 12th week of tenure, and we observe them for one year. We show that—particularly for men—the number of days of absence per week increases significantly once employment protection is granted at the end of probation. This suggests that the provision of employment protection causes the increase in absenteeism. Alternative explanations based on career concerns or on learning about social norms would predict a smooth relationship between absenteeism and tenure instead of the observed discrete jump. This consequence of employment protection seems to have been neglected in European policy debates so far. (JEL: J2, D2, D8, M5) 相似文献

Variability in PAH-DNA Adduct Measurements in Peripheral Mononuclear Cells: Implications for Quantitative Cancer Risk Assessment 总被引:2,自引:0,他引:2

Biomarkers such as DNA adducts have significant potential to improve quantitative risk assessment by characterizing individual differences in metabolism of genotoxins and DNA repair and accounting for some of the factors that could affect interindividual variation in cancer risk. Inherent uncertainty in laboratory measurements and within-person variability of DNA adduct levels over time are putatively unrelated to cancer risk and should be subtracted from observed variation to better estimate interindividual variability of response to carcinogen exposure. A total of 41 volunteers, both smokers and nonsmokers, were asked to provide a peripheral blood sample every 3 weeks for several months in order to specifically assess intraindividual variability of polycyclic aromatic hydrocarbon (PAH)-DNA adduct levels. The intraindividual variance in PAH-DNA adduct levels, together with measurement uncertainty (laboratory variability and unaccounted for differences in exposure), constituted roughly 30% of the overall variance. An estimated 70% of the total variance was contributed by interindividual variability and is probably representative of the true biologic variability of response to carcinogenic exposure in lymphocytes. The estimated interindividual variability in DNA damage after subtracting intraindividual variability and measurement uncertainty was 24-fold. Inter-individual variance was higher (52-fold) in persons who constitutively lack the Glutathione S-Transferase M1 (GSTM1) gene which is important in the detoxification pathway of PAH. Risk assessment models that do not consider the variability of susceptibility to DNA damage following carcinogen exposure may underestimate risks to the general population, especially for those people who are most vulnerable. 相似文献

Objective. We apply economic theories of news to explain differences between English‐ and Spanish‐language newspaper coverage of immigration. Methods. Using content analysis and contextual data, we examine newspaper coverage of immigration as a function of economic incentives of news organizations and the language of the newspaper outlet. Results. The results indicate that Spanish‐language news outlets generate a larger volume of coverage and more positive coverage of immigration when compared to English‐language news outlets. Conclusions. This specific topic is important and politically relevant because of the potential implications variability in media coverage of this issue hold for public opinion on immigration. 相似文献

Techniques for performing scientific risk assessments for a wide variety of chemical and radiological hazards present in the environment and workplace are available. Speakers at a workshop sponsored by the Environmental and Public/Occupational Health Standard's Steering Group addressed both the state-of-the-art in risk assessment and areas of difficulty that require further research. The Steering Group concluded that within the limits of the available data, risk-assessment techniques are a useful tool in decision-making. In the past, many government agencies have not been effective either in listening to public concerns or in communicating technical or scientific information about risks. This has been true at all levels of government. Workshop speakers discussed some ways that government agencies can more effectively communicate with the public. The Steering Group concluded that major efforts must be made to ensure that two-way communication takes place. Thus the results of the workshop show that effective management of risk requires both a scientific assessment of risk and a responsive consideration of the public's perception of risk. Intensive efforts must be made to ensure that effective two-way communication takes place between members of the public and the appropriate government agencies. 相似文献

This study investigated stereotypes of heterosexual, gay, and bisexual men in a sample of 112 psychotherapists. Stereotypes were assessed with an open-ended measure asking participants to list characteristics that they associated with one of the three groups of men. Thematic analysis of these characteristics yielded 14 stereotype categories, including categories that reflected psychosocial difficulties (e.g., Depressed and Anxious), gender roles (e.g., Female Gender Role Attributes), and personality (e.g., Open-Minded). Sexual orientation differences were found for 8 of the 14 categories. For example, therapists were most likely to associate open-mindedness with bisexual men, traditional male gender role attributes with heterosexual men, and intelligence with gay men. Implications of results for practice and training are discussed. 相似文献

This study analyses gender differences in the intergenerational earnings mobility of second‐generation migrants in Germany. Thereby it takes into account the influence of assortative mating and the parental integration. First, intergenerational earnings elasticities are estimated at the mean and along the earnings distribution. The results do not reveal large differences in the mobility — neither between natives and migrants nor between men and women. Second, intergenerational changes in the relative earnings position are analysed. These results confirm that migrants are mostly as (im)mobile as the native population. 相似文献
