The construction of public problems has a lasting influence on implementation in a given policy subsystem. National and sociopolitical contexts influence issue definition differently across nations. However, the degree to which nation-specific issue definition takes place has been insufficiently explored. In recent years, the growing incidence of autism has led to a quest for causal factors. One hypothesis posits that the use of mercury in vaccines may be a culprit. This paper examines the definition of the mercury and autism issue in Australia, Canada, the United Kingdom, and the United States. Insights into the comparative elements of issue definition are suggested by the case. These insights are of particular importance to administrators, as agencies are deeply involved as objects and actors in the process of issue definition and are often responsible for implementing new and redefined policies.  相似文献

Tax design decisions are subject to many influences, including economic and political realities. Those who make tax policy at the state level are under constant pressure to modify taxes and tax structures at the margin. In making their decisions, policy makers must assess and weigh the often conflicting advice that results from varying outlooks and interests among, as well as within, the groups providing such input.
Using Hawaii's liquor tax as a case study, this paper illustrates how seemingly innocuous policy meddling can turn a good tax into a bad one. The events that led the Hawaii Legislature to decide to substitute a flawed gallonage levy for a successful ad valorem tax are reviewed. The relative merits of ad valorem and per-unit liquor taxes are discussed. Implications of adoption of the gallonage tax are presented. Finally, the article discusses the reasons why meddling may be attractive to both taxpayers and those who levy the tax, and it concludes that tax design criteria should include disincentives to meddle as a reasonable principle of taxation.  相似文献

We examine whether nations, faced with the threat of terrorism, will be motivated to engage in the efficient amount of retaliation against terrorists. We demonstrate that the problem confronting the efforts of nations to achieve an optimal retaliation against terrorists is understated by the traditional free-rider analysis. In particular, nations have the option of actually selling or reducing the public good of retaliation, provided through the efforts of others, by offering safe havens to terrorists in return for the terrorists' pledge to attack elsewhere. This paid-rider behavior is also shown to apply to other public good scenarios.The authors gratefully acknowledge the helpful comments of Gordon Tullock on an earlier draft.

This essay asks what might be most usefully studied in future analyses of the impact of groups on the voting behavior of individuals. A dimension of group analysis so far neglected concerns some value orientations that affect the relevance of group consciousness to voting or other political behavior. In particular, the legitimacy of group political action and of group politics more generally is of central importance. Connected to such evaluations is the character of group comparisons, such as in group-focused relative power deprivation. Also of relevance are competing political value constellations, especially individualism and majoritarianism. By the use of a variety of National Election Studies and Wisconsin survey data, these themes are explored empirically to show the extent of a group focus that goes beyond the usual measures of group consciousness. Relative approval of group-based pluralism is also shown to affect the patterns of relationships of major predictors of turnout. And finally, a LISREL analysis is presented that shows that a group focus is as important as a party focus in affecting the level of political alienation pertinent to voter participation.  相似文献

This article examines the mode of understanding and experiences of family relationships of Chinese migrant women in Britain. In contrast to much existing research work on the patterns and experiences of postwar settlement of unskilled Chinese male labourers in Britain, the focus here is on the life stories of 41 Chinese women with different migration trajectories and varying economic and cultural capital. Their oral testimonies reveal Chinese women's diverse expectations and experiences of migrant family relationships and their different strategies to achieve self-fulfillment both within and outside the confines of the migrant family. For some women, migration brings opportunities for a fulfilling and independent lifestyle. They are successful in negotiating their way around and sometimes out of their initial familial and social position. For others, they bear the disproportionate cost and labour of familial strategies of advancement and remain vulnerable to the most constraining aspects of diasporic existence.  相似文献

A method for simultaneous enantiomeric separation of ephedrine, pseudoephedrine, and methamphetamine (MA) in a single run by simple capillary zone electrophoresis (CZE) with beta-cyclodextrin as a chiral selector is described. The effects of the buffer pH, phosphate concentration, beta-cyclodextrin concentration, voltage and temperature on the peak resolution were examined. Good enantiomeric resolution was attained for each analyte under our optimized conditions: 15 mM beta-cyclodextrin, 300 mM NaH2PO4 at pH 2.5 with an uncoated capillary (64.5 cm x 50 microm), applied potential at 20 kV and temperature at 30 degrees C. Ultraviolet (UV) detection at a fixed wavelength (200 nm) was employed using a diode array detector. Using phentermine as an internal standard, migration times for all analytes are reproducible within 0.16% for intra-day and 0.6% for inter-day runs. Application of this method to the analysis of confiscated drugs is discussed.  相似文献
