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.
AbstractDirectionality can be seen in many stationary time series from various disciplines, but it is overlooked when fitting linear models with Gaussian errors. Moreover, we cannot rely on distinguishing directionality by comparing a plot of a time series in time order with a plot in reverse time order. In general, a statistical measure is required to detect and quantify directionality. There are several quite different qualitative forms of directionality, and we distinguish: rapid rises followed by slow recessions; rapid increases and rapid decreases from the mean followed by slow recovery toward the mean; directionality above or below some threshold; and intermittent directionality. The first objective is to develop a suite of statistical measures that will detect directionality and help classify its nature. The second objective is to demonstrate the potential benefits of detecting directionality. We consider applications from business, environmental science, finance, and medicine. Time series data are collected from many processes, both natural and anthropogenic, by a wide range of organizations, and directionality can easily be monitored as part of routine analysis. We suggest that doing so may provide new insights to the processes. 相似文献
Objectives: We examined the social, relational and network determinants of condom use and HIV testing among men who have sex with men (MSM) in Beirut. Methods: Two-hundred thirteen men were recruited via respondent driven sampling and administered a survey. Results: Sixty-four percent reported unprotected anal intercourse (UAI), including 23% who had UAI with unknown HIV status partners (UAIU); 62% of participants had tested for HIV. In multivariate analysis, being in a relationship was associated with UAI and HIV testing; lower condom self-efficacy was associated with UAIU and HIV testing; gay discrimination was associated with UAIU; MSM disclosure was associated with UAI, UAIU and HIV testing; and network centralization was associated with HIV testing. Conclusions: Multi-level social factors influence sexual health in MSM. 相似文献
Analysing data from the Indian information technology (IT) industry, this paper advances an understanding of cultural singularities of ‘Indianness’. The research context of an intercultural meeting place of IT and business process outsourcing firms’ overseas subsidiaries, Belgium in this case, allows the authors to identify 10 cultural singularities that typify ‘Indianness’. This ethnographic, reflexive study is further validated by employing Ghoshal's ‘smell of the place’ metaphor through the authors collective experiences as consultants and researchers, and builds and extends upon the popular cultural dimension frameworks for understanding intercultural business and management. Existing cultural dimensions do not sufficiently describe the contemporary intercultural dynamics that typically take place in workplaces, especially so in offshore and outsourcing environments. A provisional set of parameters for understanding Indian culture, with its relevant impact on business life (customs and manners), business processes and business deliverables are proposed in this study. 相似文献
More and more wireless networks and devices now operate on multiple channels, which poses the question: How to use multiple channels to speed up communication? In this paper, we answer this question for the case of wireless ad-hoc networks where information dissemination is a primitive operation. Specifically, we propose a randomized distributed algorithm for information dissemination that is very near the optimal. The general information dissemination problem is to deliver \(k\) information packets, stored initially in \(k\) different nodes (the packet holders), to all the nodes in the network, and the objective is to minimize the time needed. With an eye toward the reality, we assume a model where the packet holders are determined by an adversary, and neither the number \(k\) nor the identities of packet holders are known to the nodes in advance. Not knowing the value of \(k\) sets this problem apart from broadcasting and all-to-all communication (gossiping). We study the information dissemination problem in single-hop networks with bounded-size messages. We present a randomized algorithm which can disseminate all packets in \(O(k(\frac{1}{\mathcal {F}}+\frac{1}{\mathcal {P}})+\log ^2n)\) rounds with high probability, where \(\mathcal {F}\) is the number of available channels and \(\mathcal {P}\) is the bound on the number of packets a message can carry. Compared with the lower bound \(\varOmega (k(\frac{1}{\mathcal {F}}+\frac{1}{\mathcal {P}}))\), the given algorithm is very close to the asymptotical optimal except for an additive factor. Our result provides the first solid evidence that multiple channels can indeed substantially speed up information dissemination, which also breaks the \(\varOmega (k)\) lower bound that holds for single-channel networks (even if \(\mathcal {P}\) is infinity). 相似文献
With technological advances in data-manipulation, the increased 'informability' of our daily lives and the potential for social management, surveillance has become a key site for understanding the workings of power within the global informational economy. Jeremy Bentham's Panopticon has, courtesy of Foucault, become a dominant metaphor in surveillance studies. This central eye, aimed at the moral reform of institutionalized bodies and operating through a de facto closure of individual agency, tends to limit our conception of the complex ways surveillance serves and disrupts power. Through analysis of commercial and workplace surveillance, this paper shows that power is contested and agency never completely closed down. To comprehend this negotiated relationship, an alternative framework - 'plague management' - is presented. This envisions surveillance within a social setting operated by multiple agents who themselves are open to the gaze of those surveyed. The aim of this project is to categorize rather than to reform and cure, and moreover space is available for resistance. On the global scale, new technologies have opened up space for informal, local surveillances to be effectively linked to media and Internet audiences. These 'surveillance networks', informal alliances of a variety of actors, have the potential to radically alter orthodox relations of power by evading the information controls of the state and connecting a local gaze with the global community. This paper concludes that although surveillance studies has rightly been concerned with the control capacities of IT, a balance must be actively sought with the facilitative, enabling and even democratic impulses nascent in the new technology. 相似文献
While piece rates are routinely associated with higher productivity and wages, they can also generate unanticipated effects.
Using cross-country European data, we provide among the first general survey evidence of a strong link between piece rates
and workplace injury. Despite controls for workplace hazards, job characteristics and worker effort, piece rates workers suffer
a 5 percentage point greater likelihood of injury. This remains despite attempts to control for endogeneity and heterogeneity.
As piece rate wage premium estimates rarely control for injury likelihood, this raises the specter that part of that premium
reflects a compensating wage differential for risk of injury. 相似文献
The transfer of advantage and disadvantage across multiple generations is receiving increasing attention in the international literature; however, transfers of resources across multiple generations in Australian families are less well understood. Using a longitudinal dataset of Australian children, we have the opportunity to not only investigate the transfer of educational resources across three generations in Australia, but also investigate the gendered nature of these transfers, which has been a limitation of other studies. We find no evidence of individual grandparent education effects on numeracy and reading scores for grandchildren in Year 3, independent of parent educational attainment and other covariates. However, significant effects on numeracy and reading scores were observed for children in families where both the grandmother and grandfather in maternal and paternal grandparent sets had high educational attainment (a diploma or university qualification), and where either or both the mother and father had a university qualification. These results suggest that the contribution of grandparents to the academic achievement of grandchildren cannot be fully explained by the parent generation and that the concentration of human capital in families contributes to educational inequalities across multiple generations that can be observed by eight years of age. 相似文献
