Objective. This study investigates whether variations in democratic institutions influence foreign policy outcomes. Specifically, it examines whether democracies differ systematically in their inclination to join international organizations. Methods. The study performs negative binomial estimation analysis of the relationship between IGO membership and variations in democratic structure. Results. It finds that a more competitive party system and multiple legislative chambers, especially for wealthy and stable Western democracies, contribute to more IGO memberships. Conclusions. From our findings we infer that consensus democracies adopt a kinder, gentler foreign policy that includes more willingness to participate in multilateral, cooperative international institutions, relying on negotiation and compromise to reach mutually acceptable arrangements for dealing with common problems. This assertion fits with a fundamental Kantian thesis: that the more representative and accountable a society's political institutions are, the more peaceful that society is likely to be. 相似文献

Skewness is often present in a wide range of geostatistical problems, and modeling it in the spatial context remains a challenging problem. In this article, we propose and study a new class of spatial skew-normal random fields, defined in terms of the closed multivariate skew-normal distribution. Such fields can be written as the sum of two independent fields: one Gaussian and the other truncated Gaussian. We derive theoretical expressions for the first- and second-order moments, and use them within a method of moments based procedure to estimate the parameters of the model. Data simulated from the model are used to illustrate the methodology developed. 相似文献

Leadership in both private and public institutions is devoting considerable attention to the effects of rapidly increasing rates of environmental change on its areas of responsibility. To fulfill the requirements of their obligations to customers and the firm, marketing executives, particularly, must be aware of and responsive to events external to the business.The study upon which this article is based, sought to uncover the perceptions of senior marketing executives in leading U.S. industrial corporations concerning the importance of several environmental issues to their marketing strategies, tactics and operating performance expectations for the 1970s. Awareness and response tendencies of executives to the following items were investigated: (1) the role of marketing in the firm; (2) consumerism; (3) air and water pollution; (4) urban substandard housing; (5) deterioration of downtown areas; (6) consumer market changes; (7) distribution system changes; (8) civil rights movement; (9) nature and intensity of competition. The competition was completed just prior to the emergence of the energy crisis and the removal of price controls in the U.S. 相似文献

The concept of anomie is one of the classics of sociological theory. Developed by scholars such as Emile Durkheim and Robert
K. Merton, the concept refers to the absence of clear social norms and values and to a lack of sense of social regulation.
However, whereas Merton focused on features of relative deprivation that cause anomie, Durkheim was primarily interested in
the link between rapid social change and social anomie. According to the latter, normative regulation is threatened with being
undermined and people are likely to lack the social and psychological means for adjustment in times of rapid social change.
Drawing on survey data from the South African General Household Survey polled in 2002, the article examines the ethnical differences
in levels of social anomie in the South African society. In order to do so, we, first, place the South African levels of anomie
into comparative context. In a second step, we look at the race specific levels of anomie. Third, we investigate whether the
differences in anomie between the races are related to the still existing socio-economic inequalities or whether race can
be regarded as an independent factor that impacts on anomie. Finally we scrutinize to what extent socio-economic factors account
for different levels of anomie within the races. 相似文献

In this paper, we consider testing the location parameter with multilevel (or hierarchical) data. A general family of weighted test statistics is introduced. This family includes extensions to the case of multilevel data of familiar procedures like the t, the sign and the Wilcoxon signed-rank tests. Under mild assumptions, the test statistics have a null limiting normal distribution which facilitates their use. An investigation of the relative merits of selected members of the family of tests is achieved theoretically by deriving their asymptotic relative efficiency (ARE) and empirically via a simulation study. It is shown that the performance of a test depends on the clusters configurations and on the intracluster correlations. Explicit formulas for optimal weights and a discussion of the impact of omitting a level are provided for 2 and 3-level data. It is shown that using appropriate weights can greatly improve the performance of the tests. Finally, the use of the new tests is illustrated with a real data example. 相似文献

A weighted spatial median is proposed for the multivariate one-sample location problem with clustered data. Its limiting distribution
is derived under mild conditions (no moment assumptions) and it is shown to be multivariate normal. Asymptotic as well as
finite sample efficiencies and breakdown properties are considered, and the theoretical results are supplied with illustrative
examples. It turns out that there is a potential for meaningful gains in estimation efficiency: the weighted spatial median
has superior efficiency to the unweighted spatial median particularly when the cluster sizes are widely disparate and in the
presence of strong intracluster correlation. The unweighted spatial median for clustered data was considered earlier by Nevalainen
et al. (Can J Statist, in press, 2007). The proposed weighted estimators provide companion estimates to the weighted affine
invariant sign test proposed recently by Larocque et al. (Biometrika, in press, 2007). An affine equivariant weighted spatial
median is discussed in parallel. 相似文献

This paper considers ways in which truancy, as a form of social exclusion, has its origins in the history and politics of compulsory education. Despite widespread concern expressed about declining standards, rising indiscipline, incompetent teachers, outmoded curriculum and mounting truancy in the U.K., it is argued here that such issues are not new. Thus, for the purposes of the paper contemporary research, policy and media hype, premised on ‘discovery’ of declining standards of behaviour and school attendance, is questioned precisely because the level of analysis from which they begin is inadequate. Hence, two interrelated aspects of this phenomenon are considered. The first concerns a socio-historical account of compulsory education as it is mediated by the relations between family, law and economy. Here, questions regarding whose interests state education serves, and the juxtaposing of education vs schooling are considered. The second concerns the relatively recent status of mass schooling and shifting definitions as changing policy, historical, political, economic and legal conditions alter its relationship with parents, pupils and the world of work. In this respect the paper adopts an interdisciplinary approach to an inter-agency phenomenon. What the paper seeks to demonstrate is the way truancy touches on a sensitive and deeply embedded social nerve, which has its root in the very history and ethos of compulsory state education and its worth. 相似文献

FAMILY STRUCTURES OF ASSAULTIVE ADOLESCENTS 总被引:1,自引:0,他引:1
This study compared 17 assaultive adolescents and 12 nonassaultive adolescents on a measure of family structure which assesses the family's perceptions of the authority hierarchy and the amount of closeness and distance between family members. The results demonstrated that the experimental group significantly more often perceived the presence of a reversal in the generational hierarchy of authority. The authors discuss the meaning of these results as they relate to violent teenagers and their family interactions. 相似文献
