Using 1980 census data, this study seeks to explain variations in race‐specific measures of general assistance among 109 U.S. cities. Four hypotheses (derived from developmental, conflict, and human ecological theories) are developed as potential explanations of welfare recipiency rates and payment levels. Three control variables (southness, population size, and education) are included in the analysis. Ordinary least squares (OLS) regression analysis reveals that for blacks, poverty, level of manufacturing employment (1970–1980), and southness are significant predictors of recipiency rates; whereas per capita revenue, segregation, southness, and population size are significant predictors of mean payment. For whites, poverty, percent white, and southness are significant predictors of welfare rates; whereas per capita revenue, percent white, segregation, and southness are significant predictors of mean payment. The analysis provides partial support for the need hypothesis in explaining General Assistance recipiency with respect to both races. It also provides moderate support for the segregation hypothesis and weak support for the functional transformation hypothesis in explaining General Assistance recipiency for blacks.  相似文献

In this interview, the coeditors, along with other contributors, ask Judith Butler a variety of questions regarding queer theory, gender identities, scientific and legal discourse, bodily abjection, race and class positioning, and political organizing. This range of subject matter suggests not only the breadth of Butler's work, but also its applicability to any number of people, whose relation to theory ranges from highly politicized to politically indifferent. The interview demonstrates the responsiveness of Butler's work to cultural translation and political action.  相似文献

A regional solution to the strategy and structure of multinationals   总被引:1,自引:1,他引:0  
The transnational solution developed by Bartlett and Ghoshal is shown to be suitable for only a few special cases of multinational enterprise (MNE) strategy and structure. As MNEs have most of their assets and sales within their home region, they are in need of regional, not transnational strategy and structure. Here we provide data on the regional dimension of assets and sales of the world’s largest 500 multinationals. We explore how the empirical reality of a regional concentration of assets and sales imposes a regional solution, rather than the transnational solution.  相似文献

Fluctuations in aggregate crime rates contrary to recent shifts in the age distribution of the U.S. population have cast doubt on the predictive power of the age–crime hypothesis. By examining a longer time horizon, back to the early 1930s, we show that the percentage of the young population is a robust predictor of the observed large swings in the U.S. murder rate over time. However, changes in the misery index—the sum of the inflation and unemployment rates—significantly contribute to explaining changes in the murder rate. This applies, in particular, to those changes that are at odds with the long-run trend of the U.S. age distribution, such as the decline in the murder rate in the latter part of the 1970s or its increase starting around the middle of the 1980s.  相似文献

For clustering mixed categorical and continuous data, Lawrence and Krzanowski (1996) proposed a finite mixture model in which component densities conform to the location model. In the graphical models literature the location model is known as the homogeneous Conditional Gaussian model. In this paper it is shown that their model is not identifiable without imposing additional restrictions. Specifically, for g groups and m locations, (g!)m–1 distinct sets of parameter values (not including permutations of the group mixing parameters) produce the same likelihood function. Excessive shrinkage of parameter estimates in a simulation experiment reported by Lawrence and Krzanowski (1996) is shown to be an artifact of the model's non-identifiability. Identifiable finite mixture models can be obtained by imposing restrictions on the conditional means of the continuous variables. These new identified models are assessed in simulation experiments. The conditional mean structure of the continuous variables in the restricted location mixture models is similar to that in the underlying variable mixture models proposed by Everitt (1988), but the restricted location mixture models are more computationally tractable.  相似文献

Project Success: A Multidimensional Strategic Concept   总被引:12,自引:0,他引:12  
Aaron J.  Dov  Ofer  Alan C. 《Long Range Planning》2001,34(6):699-725
This article presents projects as powerful strategic weapons, initiated to create economic value and competitive advantage. It suggests that project managers are the new strategic leaders, who must take on total responsibility for project business results. Defining and assessing project success is therefore a strategic management concept, which should help align project efforts with the short- and long-term goals of the organization. While this concept seems simple and intuitive, there is very little agreement in previous studies as to what really constitutes project success. Traditionally, projects were perceived as successful when they met time, budget, and performance goals. However, many would agree that there is more to project success than meeting time and budget. The object of this study was to develop a multidimensional framework for assessing project success, showing how different dimensions mean different things to different stakeholders at different times and for different projects. Given the complexity of this question, a combination of qualitative and quantitative methods and two data sets were used. The analysis identified four major distinct success dimensions: (1) project efficiency, (2) impact on the customer, (3) direct business and organizational success, and (4) preparing for the future. The importance of the dimensions varies according to time and the level of technological uncertainty involved in the project. The article demonstrates how these dimensions should be addressed during the project’s definition, planning, and execution phases, and provides a set of guidelines for project managers and senior managers, as well as suggestions for further research.  相似文献

Books vs. articles: Two ways of publishing sociology   总被引:1,自引:0,他引:1  
Sociologists tend to publish either in the form of articles in scholarly journals or in the form of books. This paper attempts to show that not only do specific university departments have scholarly cultures emphasizing one or the other, but that structural and demographic factors — such as location, public or private status, and size — are correlated with each. Book departments tend to be found at exclusive private universities in or near big cities on both coasts, while article-producing departments tend to be in land grant universities in the South and Midwest. Recognizing that such publication decisions are not purely scientific in nature but are also partially socially constructed ought to allow us to have more diversity in how departments structure their scholarly cultures.  相似文献
