Since the events of 9/11, security concerns have gained unprecedented dominance on western governments' national and international political agendas; Greece has been no exception. The success or failure of a far right party, like Golden Dawn, depends on the effectiveness of the government to regulate immigration and to develop policies aimed at combating the racism which pervades the political culture of society at this particular juncture, when the country is experiencing severe crisis. The aim is to provide an account of the rationale of the securitization of migration from the perspective of Greek security professionals. We argue that the extreme securitizing perceptions of security professionals have been exploited and assisted by far‐right extremist groups, which instilled racial violence, hate speech/crime into society, resulting in patterned, unreflective, and routinized security practices and discourses which are more in line with the beliefs and values advocated by the extreme right. 相似文献

We study a manufacturer's optimal multiple‐sourcing strategies when some but not all suppliers face risks of complete supply disruptions. Using an approximate model, we show that the optimal unreliable orders are ranked by a simple and intuitive criterion, and are invariant of minor market size changes. Furthermore, when ordering from one reliable and one unreliable supplier, we show that the total order quantity and its allocation between the two suppliers are independent decisions. We then test and confirm the robustness of the insights without the approximation, as well as when we relax various assumptions. 相似文献

A number of parametric and non-parametric linear trend tests for time series are evaluated in terms of test size and power, using also resampling techniques to form the empirical distribution of the test statistics under the null hypothesis of no linear trend. For resampling, both bootstrap and surrogate data are considered. Monte Carlo simulations were done for several types of residuals (uncorrelated and correlated with normal and nonnormal distributions) and a range of small magnitudes of the trend coefficient. In particular for AR(1) and ARMA(1, 1) residual processes, we investigate the discrimination of strong autocorrelation from linear trend with respect to the sample size. The correct test size is obtained for larger data sizes as autocorrelation increases and only when a randomization test that accounts for autocorrelation is used. The overall results show that the type I and II errors of the trend tests are reduced with the use of resampled data. Following the guidelines suggested by the simulation results, we could find significant linear trend in the data of land air temperature and sea surface temperature. 相似文献

We show that the linear process bootstrap (LPB) and the autoregressive sieve bootstrap (AR sieve) are, in general, not valid for statistics whose large-sample distribution depends on moments of order higher than two, irrespective of whether the data come from a linear time series or not. Inspired by the block-of-blocks bootstrap, we circumvent this non-validity by applying the LPB and AR sieve to suitably blocked data and not to the original data itself. In a simulation study, we compare the LPB, AR sieve, and moving block bootstrap applied directly and to blocked data. 相似文献

A general rate estimation method based on the in‐sample evolution of appropriately chosen diverging/converging statistics has recently been proposed by D.N. Politis [C. R. Acad. Sci. Paris, Ser. I, vol. 335, pp. 279–282, 2002] and T. McElroy & D.N. Politis [Ann. Statist., vol. 35, pp. 1827–1848, 2007]. In this paper, we show how a modification of the original estimators achieves a competitive rate of convergence. The modified estimators require the choice of a tuning parameter; an optimal such choice is generally a non‐trivial problem in practice. Some discussion to that effect is given, as well as a small simulation study in a heavy‐tailed setting. 相似文献

In postwar Western Europe social policies in the wider sense relied in many countries on neo‐corporatist policies of implementation. Since the 1980s such policies have ceased to be as dominant as they used to be, being associated with what has been called “policy communities” and “policy networks”. As far as the reforms pursued by many countries in order to readjust their economies and labour markets are concerned, significant shifts of such a kind were observed. Illustrations of these trends are presented in a comparative section. We attempt to demonstrate the dual structures of social policy formation and implementation, i.e. neo‐corporatist and network/policy community policies, and to discuss the “how” of such policies, i.e. their “raison d’être” and their “real world” enforcement. Against a background of various semi‐corporatisms and adversarial trade union politics, Greece is trying at the moment to adopt this pattern in several social policy areas, though this is not yet quite visible. Neo‐corporatism is also enhanced. We attempt to show where neo‐corporatism is tried (e.g. certain “social dialogue” structures) and where policy communities are encouraged (e.g. public health, local social policies, etc.). Sometimes the boundaries between the two systems are blurred, with some social dialogue committees appearing as quasi‐policy communities. Finally we endeavour to examine the outcomes of such policies and to see their inner logic against the theoretical background. The concept of multilevel governance as a wider policy instrument which incorporates both the above systems is of special interest here. 相似文献

One of the defining features of the home credit sector is the role played by its agents—workers who act as intermediaries between lending companies and borrowers to facilitate lending and collect repayments. There is a prevailing and pervasive narrative in the sector that women make superior agents, largely based on the belief that female agents can manage relationships with borrowers more successfully than their male counterparts. This article analyzes data from 349,078 home credit accounts (loans), as well as 71 interviews with home credit agents and lending company managers, to evaluate both the myths and realities of women's roles in home credit. The data is also used to explore the opportunities for—and potential constraints on—women's career progression in home credit work, based on an understanding of the moral economy in which they operate. By exploring the moral economy of low-income communities, the article highlights the role of working-class women's cultural capital within the labor market. Despite women forming the majority of the agent workforce in home credit, women's capital is undervalued in comparison with their male counterparts' capital. The analysis within this article allows a greater understanding of the highly classed and gendered nature of the moral economy of low-income communities and the exchange value of women's capital within the labor market. 相似文献
