The authors consider a finite population ρ = {(Yk, xk), k = 1,…,N} conforming to a linear superpopulation model with unknown heteroscedastic errors, the variances of which are values of a smooth enough function of the auxiliary variable X for their nonparametric estimation. They describe a method of the Chambers‐Dunstan type for estimation of the distribution of {Yk, k = 1,…, N} from a sample drawn from without replacement, and determine the asymptotic distribution of its estimation error. They also consider estimation of its mean squared error in particular cases, evaluating both the analytical estimator derived by “plugging‐in” the asymptotic variance, and a bootstrap approach that is also applicable to estimation of parameters other than mean squared error. These proposed methods are compared with some common competitors in simulation studies. 相似文献

In this paper we propose a generalization of the Shapiro and Botha (1991) approach that allows one to obtain flexible spatio-temporal stationary variogram models. It is shown that if the weighted least squares criterion is chosen, the fitting of such models to pilot estimations of the variogram can be easily carried out by solving a quadratic programming problem. The work also includes an application to real data and a simulation study in order to illustrate the performance of the proposed space-time dependency modeling. 相似文献

It is often assumed that in Germany the situation in Turkish families can be characterized by traditionalism, a patrilineal organization of family relationships and a rigid gender role orientation including a traditional gender division between gainful employment and housework. Against this background one would expect Turkish parents to have a particular strong interest in a high educational attainment of their sons and consequently they should invest more in their education. This article examines whether there is evidence for such preferences and relevant behaviours. An analysis of official school statistics of the federal state North-Rhine Westphalia shows that Turkish boys are more likely to make a transition to a Gymnasium than Turkish girls. However, a systematic preference of Turkish parents of a transition to secondary education for their sons cannot be confirmed by way of micro data. Moreover results from our macro data indicate that already in grade seven the gender ratio is reversed. All in all our analyses indicate that there is no significant and sustainable disadvantage for Turkish girls in comparison to Turkish boys. 相似文献

This paper evaluates the execution of an ERP – enterprise resource planning in a production process. The changes that were made to processes to make them compatible with ERP modules and adaptations that were required by the ERP implementation are presented. The presented study is different from the normal patterns of a vertical implementation, since its application is not direct. In order to use the standard modules of the ERP system, the internal processes were embellished and the data collection steps were integrated into the production process (production orders, inventory, production, daily consumption, daily output). The case study shows that the ERP implementation caused an improvement of the processes in the areas adjacent to production (purchasing, logistics, distribution, supply and sales). In conclusion, this paper presents the main advantages and disadvantages of the ERP system implementation, as well as some considerations and recommendations for the future ERP implementations. 相似文献

In State, Power, Socialism, Nicos Poulantzas conceptualized a state that materializes and concentrates power and displaces the class struggle from the economic to the political arena. In the past twenty years, much has changed. We argue that economic relations have been transformed by economic globalization, work reorganization, and the compression of space, time, and knowledge transmission through an information and communications revolution. Knowledge is far more central to production, and the locus of the relation between power and knowledge has moved out of the nation state that was so fundamental to Poulantzas’ analysis. 相似文献

We investigate whether the members of the Governing Council of the European Central Bank take into account the specific economic conditions of their states of origin, to set the interest rates for the euro area. Testing the national-based view against the Europeanist perspective is a challenging issue, because voting inside the Governing Council is secret, and the final outcome depends both on the individual preferences and the procedures followed by the Governing Council to arrive at a decision. Accordingly, we model interest rate setting as a two-stage process: first, each member of the Governing Council sets his/her preferred rate, and next the Governing Council meets and decides the actual figure. Our empirical analysis shows that domestic developments play a major role in determining the preferred interest rate of the each member; and that some members exert agenda setting power, that precludes some interest rate policies to be considered at the meeting. 相似文献

Latin America is emerging from a century of transformation – from a traditional agrarian to an urban industrial economy – where countries have taken diverse historical paths. Some have almost completed this transformation, others are taking early steps, and most are living through it. State‐led transition has followed two successive development strategies. From the 1920s to the 1980s, state developmentalism, for the most part, successfully assumed the twin challenges of economic and social progress. In the final decades of the century, Latin American states adopted the policies of the Washington consensus, which emphasized the importance of business in the framework of globalization, benefiting the affluent few. However, an unambiguous shift in direction has been taking place in Latin America since the 1997 economic crisis. This article suggests that a new developmental welfare state model is in the making. How will it evolve over the wider space of an increasingly integrated Latin America? 相似文献

To examine whether high moral reasoning competence of adolescents is associated with low levels of bullying, and to understand whether moral disengagement mediates or moderates this relationship, 925 German children ranging from 11 to 17 years of age (M = 14.18, SD = 1.21) completed questionnaires on moral reasoning competence and moral disengagement in surveys at three different schools. The children were classified according to their bullying role, based on a peer‐nomination procedure. Multinomial logistic regression analyses showed that moral reasoning competence negatively predicted whether a student took an aggressive role. Moral disengagement partially mediated this relationship. Corresponding effects for defenders and outsiders were not found. These results extend previous findings about the effect of moral reasoning on bullying in primary school. The implications for the prevention of bullying are discussed. 相似文献

ABSTRACT In a study conducted at a major university in Spain, 648 university students between the ages of 17 and 23 years were assessed to identify the manifestations of psychological abuse prior to the consolidation of marital status (e.g., matrimony, start of cohabitation). To evaluate psychological abuse in the students’ intimate relationships, the authors created a Questionnaire on Psychological Abuse. Results show coercive patterns of interaction in the students’ dating relationships. Significant differences were found between men and women, with behavioral factors such as hostility, blaming, and abusive insistence. Future research is suggested that would permit changes in attitude and behavior to be introduced into dating relations. 相似文献
