Public administration finds itself in an era of government byperformance management, which is reflected in the widespreadassumption that management is a key determinant of performance,and that it is reasonable to expect managers to measurably improveorganizational effectiveness. This article joins a growing literaturein seeking to conceptualize and empirically test how externalenvironmental influences and internal management factors combineto create performance, relying on data from the 20022003National Administrative Studies Project (NASP-II) survey ofstate government health and human services officials. We categorizemanagerial efforts to facilitate organizational performanceas determined either through their interactions with the organizationalenvironment, or through employing workable levers to changeinternal organizational culture, structure, and technology.Among the external environmental variables we find that thesupport of elected officials and the influence of the publicand media have a positive impact on effectiveness. Among internalmanagement choices, the ability to create a developmental organizationalculture, establish a focus on results through goal clarity,and decentralize decision-making authority are all positivelyassociated with organizational effectiveness. 相似文献

This study seeks to explore transnational communication among migrants of the Irish diaspora through an examination of the Orange Order's networks. It draws upon rare local and district records and press accounts to explain the migratory links and social worlds of Orange emigrants from Ulster. The substance of the study echoes the findings of Canadian historians who have much richer records than exist in the public domain in Britain. It demonstrates how Orangemen in Ireland came to recognise the diasporic dimension of their movement, and how members used the Order to negotiate some of the pathways of migration that were an important feature of their lives, and in the lives of the working class more generally. The essay generally seeks to demonstrate that the Orange Order acted as a network of friendship, camaraderie and support for emigrants and immigrants in the British World in the late nineteenth and early twentieth centuries. 相似文献

This study examines the relationship between occupational status and fertility timing during a period of rapid development in Puerto Rico. Our fundamental hypothesis is that women with higher status occupations face greater opportunity costs than those with less valued jobs and therefore will be more likely to postpone parenthood until later ages than women without such high costs. We test this hypothesis using event history techniques with data from the 1982 Puerto Rico Fertility and Family Planning Assessment, an island-wide survey of women between the ages of 15 and 49. The analysis examines the effects of occupational status on the timing of first births, and finds strong support for the basic hypothesis, especially regarding the post-ponement of teen births. After the teen years, the effects are less pronounced. Overall, it appears that employment opportunities have played an important role in childbearing decisions in Puerto Rico.An earlier version of this paper was presented at the annual meeting of the Population Association of America, Denver, Colorado, 30 April–2 May 1992. 相似文献

In this note, we consider the problem of estimating regression coefficients when there are missing observations of some explanatory variables. Following Dagenais (1973), Gourieroux and Monfort (1981), and Conniffe (1983a, 1983b), we assume auxiliary relationships exist among explanatory varibles. Several estimatprs and their interrelationships are discussed. We begin with the model of Gourieroux and

Aspects of 47 preschoolers'emotional competence—their patterns of emotional expressiveness and reactions to others' emotion displays—were observed in two settings, with mother and with peers, and their general social competence was rated by their preschool teachers. Intrapersonal and interpersonal (i.e., socialization correlates of children's emotional competence were identified, and a causal model incorporating direct and indirect influences on social competence was evaluated. Maternal patterns of expressiveness, reactions to children's emotion displays, and self-reported affective environment were associated with children's emotional competence in the preschool. Children's emotional competence with mother predicted their emotional competence in the preschool somewhat less strongly, suggesting that emotional competence may differ according to the interpersonal relationship studied. Taken as a whole, findings reassert the importance of the domain of emotional expression to the development of social competence.Reprint requests can be sent to the author, Department of Psychology, George Mason University, 4400 University Drive, Fairfax, VA 22030. Grateful acknowledgment goes to the mothers and children who so clearly expressed and reacted to emotions; thanks also are due to Christine Alban, Joanne Ayyash, Michael Casey, Elizabeth Couchoud, Huynh Dung, Merlina Hemingway, Soueang Lay, Vanna Nguyen, Emilianne Slayden and Kimberly Sproul, as well as the director and teachers of the Project for the Study of Young Children.

This report summarizes the proceedings of a conference on quantitative methods for assessing the risks of developmental toxicants. The conference was planned by a subcommittee of the National Research Council's Committee on Risk Assessment Methodology 4 in conjunction with staff from several federal agencies, including the U.S. Environmental Protection Agency, U.S. Food and Drug Administration, U.S. Consumer Products Safety Commission, and Health and Welfare Canada. Issues discussed at the workshop included computerized techniques for hazard identification, use of human and animal data for defining risks in a clinical setting, relationships between end points in developmental toxicity testing, reference dose calculations for developmental toxicology, analysis of quantitative dose-response data, mechanisms of developmental toxicity, physiologically based pharmacokinetic models, and structure-activity relationships. Although a formal consensus was not sought, many participants favored the evolution of quantitative techniques for developmental toxicology risk assessment, including the replacement of lowest observed adverse effect levels (LOAELs) and no observed adverse effect levels (NOAELs) with the benchmark dose methodology. 相似文献

Suppose that social welfare function f satisfies the Pareto condition and has complete and transitive values. On a domain satisfying the free quadruple property, if the outcome set X has m< outcomes, then the set of pairs of distinct alternatives on which f satisfies both independence and nondictatorship contains at most the fraction 2/m of all pairs. On a domain satisfying the free six-tuple property, if X is a subset of Euclidean space then the set of pairs on which f satisfies both independence and nondictatorship has Lebesgue measure zero.Campbell's research was financed by the National Science Foundation, grant SES 9209039. 相似文献

Abstract Many race-specific differences in health outcomes that have been observed in previous research have been attributed to class and racebased group differences which either facilitate or constrain health opportunities and behaviors. These include such variables as different rates of poverty, health insurance coverage, and access to medical care. However, these relationships have been inadequately examined in rural communities where minority status may be even more detrimental to health than in urban areas, due to various constraints on access to health care. We present an analysis that assesses the effects of community, family structure, sociodemographic, and medical care variables on self-reported health status among Hispanics, Mrican Americans, and non-Hispanic whites in six rural communities in Florida. Community structural characteristics had a significant effect on self-reported health, as did some of the measures of how respondents “experience” community. These relationships held even when other sets of variables were added to the models. Family/household characteristics and sociodemographic and medical care variables were less important in explaining self-reported health status. These findings suggest that community continues to be important in explaining differences in health status in rural areas. 相似文献
