Conceptions of nationhood (i.e., who is accepted as a member of the national ingroup) are known to be more open in countries with inclusive citizenship and integration policies. Yet, surprisingly, up to now no research has investigated whether the sharedness of these conceptions is related to national policies. Therefore, relying on data from the 2013 International Social Survey Programme, the present study examined to which extent individuals living in 188 regions of 21 European countries share similar conceptions of who is a “true” member of the nation. Both ethnic (e.g., having national ancestry) and civic (e.g., respecting national laws and institutions) criteria were considered. Multilevel analyses revealed that in countries with more inclusive policies (with inclusive citizenship regimes, and where immigrants are granted more political rights) the average regional importance granted to ethnic criteria was lower, and conceptions were more heterogeneous (i.e., less shared). Civic criteria—that are achievable—were deemed more important. This can explain the lower heterogeneity of civic conceptions of nationhood and the lack of impact of national policies (though the average regional importance of these criteria was higher where immigrants had more rights). Overall, these results suggest that inclusive as opposed to exclusive settings leave more room for differing worldviews.

Perceived racial discrimination (PRD) has been implicated in undermining the mental and physical health of racial/ethnic minorities
(e.g., Williams et al. in Am J Public Health 93:200–208, 2003; Wong et al. in J Pers 71:1197–1232, 2003). Researchers have begun to explore the indirect role of health behaviors as one factor in helping to explain this relationship.
The goal of the present study was to examine the relationship between PRD and a wide range of health behaviors using a prospective,
longitudinal design and to explore the role of gender in moderating these relationships. Using data from the Maryland Adolescent
Development in Context Study, we examined the relationship between adolescent PRD (accumulated across ages 14–21) and health
behaviors (i.e., diet, substance use, exercise) at age 30 in a sample of middle-class black men and women. Using structural
equation modeling, results revealed that more cumulative PRD during adolescence was associated with less healthy eating, more
substance use (among men), and more exercise (among women) in young adulthood. Implications of these findings for understanding
the role of health behaviors in explaining the link between PRD and health outcomes are considered. 相似文献
Focus groups were conducted to appreciate the voices of Urban American Indians (UAI) who have mixed ancestries residing in
Philadelphia, Pennsylvania. Participants (15 women and 10 men, 19–83 years of age) with a variety of Native ancestries coming
from different nations (i.e., blackfeet, blackminkwa, Cherokee, Creek, Delaware, Lakota, Powhatan, Seminole, and Shawnee)
reported to also have a Non-Native racial/ethnic ancestry such as African/black, Hispanic, and/or Caucasian/white. Specifically,
this study provided evidence about (a) the complexity and challenge of being “mixed” UAI (e.g., “living a culture” as opposed
to blood quantum in determining a personal identity) (b) the linkage of cultural identities to mental health (c) contributions
of cultural activities to identities and mental health (e.g., therapeutic and healing functions of cultural activities), and
(d) very limited urban Native-oriented mental health service (e.g., visions for Native American-centered mental health clinic
in an urban setting). Building on those UAI’s voices, this paper provides a context for the need of a culturally respectful
transformation of urban mental health system by highlighting the clinical significance of cultural identity and mental health
promotion for UAI. 相似文献
Panel data in the National Longitudinal Survey of Youth (NLSY97) provide an excellent opportunity to examine the relationship between Hispanic immigration, assimilation, and retail theft. This study examines the relationship between length of time Hispanic youth have spent in America, with the probability of stealing from a store. After controlling for traditional predictors of crime that are correlated with adolescence and immigrant status, random effects logistic regression models indicate that immigrants are less likely to steal than non-immigrants. However, calculating the marginal effects of time spent in the United States reveals that their probability increases with assimilation. Supplementary analyses specify that Hispanic youth who enter the United States within their first 5 years of age will have higher odds of engaging in retail theft. Supportive parenting and a structured home environment is a consistent protective factor in the models. Policies targeting pro-family and social identification are likely to benefit immigrant youth as they acculturate to America. 相似文献
Life satisfaction is quite heterogeneously distributed across countries of the enlarged European Union. Previous research has shown how living conditions within individual countries, such as access to material and emotional resources, are important for personal well-being, but it has been less successful in explaining differences between countries. This article investigates whether it matters in which political and economic circumstances people live, as well as whether their particular perception of the quality of their societal environment plays a role. People are well aware that the institutional and cultural settings in which their lives are embedded create opportunities and limitations: within individual countries, perceptions of society influence life satisfaction outcomes irrespective of access to resources. However, their importance for well-being differs across Europe: perceptions of societies are highly decisive in countries that provide only a minimum of social security and in which the reliability of political institutions is poor. In rich and stable countries, the impact is weaker and private social support becomes more important. In addition to these country-specific weights of life satisfaction determinants, life satisfaction variations between countries can be explained to a large extent by taking into consideration the economic performance, the social security level, and the political culture in a country—all in all, general conditions that enable people to live a respectable life. 相似文献
Since Skinner's [40] landmark article depicting the manufacturing function as the “missing link” in corporate strategic processes, a portion of the blame for inferior performance in many firms has been attributed to the subordinate strategic position of manufacturing. It has been argued that part of the solution to misalignments between the capabilities possessed by manufacturing and the requirements dictated by customers is for manufacturing to take a more proactive stance. However, little research has been reported which examines manufacturing proactiveness empirically. In this paper, we address this gap by developing an operational definition of manufacturing proactiveness and testing empirically whether a link exists between proactiveness and performance based on data collected from a sample of manufacturers. Based on the manufacturing strategy literature, we identify two major dimensions of manufacturing proactiveness: (1) the degree of manufacturing's involvement in the strategic processes of the business unit; and (2) the degree of commitment to a long-term program of investments in manufacturing structure and infrastructure aimed at building capabilities in anticipation of their need. We develop reliable scales for measuring each of the dimensions of proactiveness and use the data to provide evidence of a clear link between manufacturing proactiveness and business performance. We show that investments in structural programs coupled with either high levels of manufacturing involvement in strategic processes or planned investments in infrastructural programs correlate with higher than average performance. 相似文献
Research and interventions for intimate partner violence in current use largely consist of practices aimed at getting victims to leave their abusers, rather than helping perpetrators stop their violence. In the context of parenthood, the focus on programs targeting women experiencing violence has resulted in an emphasis on mothers’ responsibility for mitigating the adverse effects of witnessing violence on children. This has led to insufficient understanding of violent men’s identities as fathers. This narrative review employed content analysis to analyze the discursive constructions of men and women as parents in a selection of peer reviewed articles about the prevention of intimate partner violence during childbearing years that were published between January 2000 and January 2015 (N = 37). A quantitative word count was conducted in order to determine the frequency with which these articles referred to men and women in their parental roles when employing prevention and intervention strategies. Women were consistently identified as mothers in all areas of the literature, while the prevalence of men’s identities as fathers was confined only to the specific, specialized area of the literature that is aimed at men alone. The implications of these findings for future research and practice in the area of prevention and intervention of intimate partner violence specifically in the context of parenthood are discussed. 相似文献
As an imperative channel for fast information propagation, online social networks (OSNs) also have their defects. One of them is the information leakage, i.e., information could be spread via OSNs to the users whom we are not willing to share with. Thus the problem of constructing a circle of trust to share information with as many friends as possible without further spreading it to unwanted targets has become a challenging research topic but still remained open. Our work is the first attempt to study the Maximum Circle of Trust problem seeking to share the information with the maximum expected number of poster’s friends such that the information spread to the unwanted targets is brought to its knees. First, we consider a special and more practical case with the two-hop information propagation and a single unwanted target. In this case, we show that this problem is NP-hard, which denies the existence of an exact polynomial-time algorithm. We thus propose a Fully Polynomial-Time Approximation Scheme (FPTAS), which can not only adjust any allowable performance error bound but also run in polynomial time with both the input size and allowed error. FPTAS is the best approximation solution one can ever wish for an NP-hard problem. We next consider the number of unwanted targets is bounded and prove that there does not exist an FPTAS in this case. Instead, we design a Polynomial-Time Approximation Scheme (PTAS) in which the allowable error can also be controlled. When the number of unwanted targets are not bounded, we provide a randomized algorithm, along with the analytical theoretical bound and inapproximaibility result. Finally, we consider a general case with many hops information propagation and further show its #P-hardness and propose an effective Iterative Circle of Trust Detection (ICTD) algorithm based on a novel greedy function. An extensive experiment on various real-world OSNs has validated the effectiveness of our proposed approximation and ICTD algorithms. Such an extensive experiment also highlights several important observations on information leakage which help to sharpen the security of OSNs in the future. 相似文献
