Consider the problem of estimating the intra-class correlation coefficient of a symmetric normal distribution. In a recent
article (Pal and Lim (1999)) it has been shown that the three popular estimators, namely—the maximum likelihood estimator
(MLE), the method of moments estimator (MME) and the unique minimum variance unbiased estimator (UMVUE), are second order
admissible under the squared error loss function. In this paper we study the performance of the above mentioned estimators
in terms of Pitman Nearness Criterion (PNC) as well as Stochastic Domination Criterion (SDC). We then apply the aforementioned
estimators to two real life data sets with moderate to large sample sizes, and bootstrap bias as well as mean squared errors
are computed to compare the estimators. In terms of overall performance the MME seems most appealing among the three estimators
considered here and this is the main contribution of our paper.

Welfare effects of demand management policies: Impact multipliers under alternative model structures
Montek S. Ahluwalia 《Journal of Policy Modeling》1979,1(3):317-342
This paper explores the sensitivity of multiplier estimates under three alternative assumptions about factor supply. For this purpose, we have used a general equilibrium model of Malaysia which allows endogenous determination of factor and output prices and which permits substitution in both production and demand in response to price. The structure of the model and three alternative factor supply assumptions under which the model can be solved are described. These alternative assumptions amount to alternative “closure rules.” The results of a general increase in demand as estimated under each of the alternative closures are then presented. Finally, we examine the results of two specific types of demand increase under each of the closure rules, focusing especially upon welfare related variables such as real household consumption levels. 相似文献

This article aims to interrupt the modernist goals of public relations research that predominantly privileges a management discourse. The emergence of the intertwined nature of cultural phenomena in the context of globalization necessitates alternative ways of thinking about public relations. This article explores the possibilities of postmodernism to disrupt the accepted norms of the dominant discourse of public relations. However, given the fragmented nature of the discursive space in postmodernism, this article advances the argument that critical modernism provides a relevant alternative to the modernist paradigm of public relations research by utilizing globalization theories. It suggests a space for articulating the roles of power and structure situated within the constitutive spaces of discourse. 相似文献

The present article addresses the support and supervisional relations of Palestinian Israeli single mothers vis-à-vis their families and communities. It links the theoretical discussion on intersectional analysis with power relations and gender. In this article I focus on the importance of employing analytical models that take into consideration the internal variance within this social category of ‘Palestinian Israeli single mothers' which emerge due to the contradictory social trends typifying Palestinian society in Israel today – models that examine the implications of the complexity of women's lives in discrete locations, the changes society is undergoing, together with processes of discrimination and the strengthening of conservative trends. The article is based on data gathered during in-depth, semi-structured interviews that were conducted and analyzed with a commitment to the principles of feminist research. 相似文献

In this paper the author argues that the Chinese theory of All-under-Heaven is the best philosophy for world governance. All-under-Heaven is a deep world concept with a trinity of meanings: the earth, people's hearts and a world institution. And it introduces a political principle, ‘world-ness’, that arguably transcends the principle of ‘internationality’. The author argues that the theory of All-under-Heaven is a more appropriate ‘world theory’ than ‘international theory’ in dealing with world problems. The author also considers the philosophies of the UN and EU. 相似文献

Many studies have refuted the opinion that urban floras are poor in total species number and characterized primarily by neophytes. Also, it has been proved that urban flora differs from its surroundings, and at the same time reflects its richness. Our study focused on urban flora, structure and similarities, and the possible correlation with the urban attributes. Therefore, we selected 11 cities in Southeast Europe, which differ in the development of transportation networks (roads, rails and inland waterways) and population size. Next, we compared two sets of data (structure of urban flora and urban attributes) to define the correlation patterns. Analyzed urban floras were primarily distinguished by a total number of species, number of unique species and neophytes. Belgrade is a city with the highest urbanization level, the most species and the highest number of unique species and neophytes as well. Kosovska Mitrovica, Grocka and Po?arevac stand out by floristic richness. These cities have a high number of species, yet a small proportion of neophytes. Other cities are characterized by similar floristic structure, with a relatively similar proportion of neophytes and approximately similar number of unique species in relation to the total number. It can be concluded that other factors beside the chosen urban attributes have additional effects on floristic structure, except for the factor - the presence of neophytes. This is in accordance with predefining subjects, since urban attributes were chosen based on knowledge about important corridors for invasive species. 相似文献
