In this paper we seek to explain the activity presidential position taking on roll call votes in the House. Position taking may help presidents pursue their policy agendas, but time and available resources constrain their ability to take positions. Even though position taking is a discretionary presidential action, it occurs in the legislative arena and, thus, presidents must consider elements in both institutions as well as outside conditions when making this decision. Accordingly, we posit a multiple perspectives approach to explain the number of presidential positions on votes in the House. Our multivariate two-stage least squares regression reveals that variables from all three environments (executive, legislative and exogenous) within our multiple perspectives approach are necessary to adequately explain presidential position taking overall and when divided according to domestic and foreign policy positions. 相似文献

Mubangizi BC, Gray M. Putting the ‘public’ into public service delivery for social welfare in South Africa Int J Soc Welfare 2011: 20: 212–219 © 2010 The Author(s), International Journal of Social Welfare © 2010 Blackwell Publishing Ltd and the International Journal of SocialWelfare. The privatisation of some essential services in South Africa has raised severe difficulties for those for whom the idea of fees for services is quite foreign and who, in any case, cannot afford to pay for services. The government has developed several initiatives to educate people about the need to pay for services provided by local government, the largest of which was the Masakhane fees‐for‐services campaign. This article describes two recent initiatives that seek to engage local citizen participation, namely, Integrated Development Plans and izimbizo (or traditional forums). These are examined along with the challenges faced by local government in promoting citizenship participation in service delivery within a decentralised system of governance. The article concludes with some recommendations on how citizen participation can be enhanced so as to make the ‘public’ visible in public service delivery and thus improve social welfare services. 相似文献

During the fall of 2001, public health law scholars at the Center for Law and the Public's Health at Georgetown and Johns Hopkins Universities were asked by the Centers for Disease Control and Prevention (CDC) and a series of national partners to develop the Model State Emergency Health Powers Act (MSEHPA). The MSEHPA provides a series of modern powers for states to consider in responding to catastrophic public health emergencies, including bioterrorism events. Since December 2001, provisions based on the MSEHPA have been introduced in nearly 40 states and passed in 20. Underlying the development of the act is a long-standing debate between legal and ethical scholars and law- and policymakers as to the appropriate ways to balance individual and communal rights. The drafting challenge was to create a comprehensive model law that provides adequate powers to protect the public's health while also respecting individual and group rights. The MSEHPA empowers public health agents with broad authority and simultaneously limits the exercise of power in time, duration, and scope to accomplish communal goals of abating serious public health threats. Coercive public health powers, particularly isolation and quarantine, are exercised on a temporary basis, only so long as are reasonably necessary and only among persons who justifiably may pose a risk to others because of their contagious conditions. Individual rights to contest the coercive use of public health powers, even during an emergency, are secured. 相似文献

Sustained mass media campaigns have been recommended to stem the tobacco epidemic in the United States. Propensity score matching (PSM) was used to estimate the effect of awareness of a national smoking cessation media campaign (EX) on quit attempts and cessation-related cognition. Participants were 4,067 smokers and recent quitters aged 18-49 in targeted U.S. media markets. Controlling for potential confounders through PSM and regression analysis, confirmed awareness of EX was not significantly associated with either outcome at 6-month follow-up. Matched analyses excluding 217 quitters resulted in a significant effect of EX on both outcomes. 相似文献

Abstract The well‐being of residents of resource dependent communities is a question of traditional interest to rural sociologists. The label “resource dependent” obscures how this relationship may vary between particular resource industries, regions, or indicators of well‐being. Few analyses have compared the relationship between well‐being and resource dependence across different industries, nor tested competing theories about the relationship between resource dependence and well‐being. Our paper presents an overview of the relationship between resource dependence—agriculture, fisheries, mining, energy, forestry—and human well‐being in Canada. Analysis of 1996 Statistics Canada data revealed a great deal of variation in the effect of “resource” dependence on indicators of well‐being (e.g., human capital, unemployment, income): some industries exhibit fairly positive outcomes (e.g., agriculture), others more negative outcomes (e.g., fishing). Consistent with analyses conducted in the United States, these relationships vary by region, suggesting the need for models that incorporate the particulars of place and industry. 相似文献
