The Articles of Confederation as the Background to the Federal Republic   总被引:1,自引:0,他引:1  
Lutz  Donald S. 《Publius》1990,20(1):55-70
The Articles of Confederation, usually neglected by those studyingthe American founding, formed an important part of the backgroundto the 1787 Constitution. The Articles functioned as the firstnational constitution of the United States and, as such, reflectedAmerican political theory as it emerged during the Revolution.Equally important, a textual analysis reveals the extent towhich the 1787 Constitution was a logical extension of the Articlesof Confederation. Most of the Articles were incorporated inthe U.S. Constitution, and several key changes found in thelater document were present in embryo in the Articles of Confederation.  相似文献

The index of socioeconomic and cultural diversity among theAmerican states formulated by John L. Sullivan for 1960 is recreatedfor 1980. Comparisons are made between the index for the twotime periods, and changes among the states are examined overtime. Significant differences continue to exist between northernand southern states, mainly because of cultural rather thansocioeconomic factors. The diversity index remains a relativelypowerful predictor of policy variation among the states and,as such, might be considered as a substitute for geographicregion in comparative state policy research.  相似文献

The "corporate liberal" regime that held together in America from the end of World War I1 to the 1960s was marked by broad agreement on ideology, public policy and a stable ruling coalition centered in the Democratic Party. This regime unraveled in the late 1960s and 1970s with the relative decline in American military and economic hegemony and the rise of a "left liberal insurgency". Key corporate liberal intellectuals and constituencies migrated to the Republican Party under Reagan. Reaganism will not sustain itself because its coalition partners are too disparate, its failure to transform the Republicans into a majority party, a lack of consensus on many issues, and the continued decline of the U.S. in the international economy. Corporate liberalism will find itself migrating to a revitalized Democratic Party, under a centrist leadership favoring fiscal responsibility, government-corporate partnerships, and a more efficient military.  相似文献

This paper considers the notion of cycle avoiding trajectories in majority voting tournaments and shows that they underlie and guide several apparently disparate voting processes. The set of alternatives that are maximal with respect to such trajectories constitutes a new solution set of considerable significance. It may be dubbed the Banks set, in recognition of the important paper by Banks (1985) that first made use of this set. The purpose of this paper is to informally demonstrate that the Banks set is a solution set of broad relevance for understanding group decision making in both cooperative and non-cooperative settings and under both sincere and sophisticated voting. In addition, we show how sincere and sophisticated voting processes can be viewed as mirror images of one another — embodying respectively, “dmemory” and “foresight.” We also show how to develop the idea of a “sophisticated agenda,” one in which the choice of what alternatives to propose is itself a matter of strategic calculation.  相似文献

This article presents an analytic model for understanding the role of decision makers in bringing about significant policy and institutional changes and in understanding how processes of agenda setting, decision making, and implementation shape the content, timing, and sustainability of reform initiatives. Central to the model is the assertion that policy elites and the policy making process are important determinants of reform. The framework indicates that circumstances surrounding issue formation, the criteria that decision makers use to select among options, and the characteristics of specific policies are analytic categories that explain a considerable amount about reform outcomes. The model is based on cases developed by participants in twelve initiatives to bring about policy and institutional change in a variety of developing countries.  相似文献

Chronic accessibility refers to a long-term bias to notice, process, and have available for recall certain types of information across a variety of different stimulus objects in a variety of different situations. This paper illustrates the usefulness of studying the chronic accessibility of political constructs in the field of political behavior. The chronic accessibility of four generic political constructs are operationalized: candidates, issues, groups, and parties. The accessibility of these four political constructs is shown to be relatively stable over time and to guide the processing of information about a wide variety of political objects. Next, a voting model is tested that identifieswhich voters will rely chiefly on issue orientations, group orientations, candidate orientations, and/or party orientations in making their vote decision. The voting model is validated across two distinct ways of operationalizing the political chronicities and three different election studies spanning a 28-year period. Finally, although this paper has focused onindividual political behavior, several ways that an information processing approach could shed light on macrolevel political questions are discussed.  相似文献

The SIPP data have provided a first look at the relative economic status of various types of Social Security beneficiaries. They have shown that the different types of Social Security beneficiaries face very different economic circumstances. Retired workers and wife beneficiaries have the highest family incomes adjusted for family size. Aged widows and minor children have the lowest family incomes, with high proportions of poor or near poor. And disabled workers are in between, but also have high proportions of poor or near poor. Retired-worker and wife beneficiary households also have considerably more asset holdings than disabled-worker or widow beneficiary households. Beneficiaries with high family incomes are very likely to live with relatives and to rely heavily on the relatives' income. The high-income families tend to have non-means-tested sources of family income other than Social Security amounting to substantial proportions of their total income and to have high asset holdings. Conversely, beneficiaries with low family incomes are very likely to live alone or with nonrelatives, to rely heavily on Social Security and means-tested benefits, and to have low asset holdings. A majority of ever-poor beneficiaries (with the exception of widow beneficiaries) are poor in only some months of a year. This situation is not consistent with the stereotype of beneficiaries living on fixed incomes. But the change in poverty status is often due to a change in the income of other family members rather than of the beneficiary. And in some cases, a change in poverty status occurs with little or no change in income as the cost of living rises.  相似文献

This attempt to classify Social Security beneficiaries by type of benefit using the new Survey of Income and Program Participation (SIPP) has yielded promising results. Evaluations of the classification algorithm based on comparison of the estimated number of beneficiaries in each of the several categories to independent estimates of the number of beneficiaries indicate that in most instances a high percentage of each category has been identified. For the most part, age and monthly benefit amount size distributions seem reasonable. Furthermore, very few persons in the sample who were identified as Social Security beneficiaries could not be assigned to one or another of the benefit groups. The classification procedure also represents a marked improvement over earlier efforts to classify type of beneficiary that relied on data from the March Supplement to the Current Population Survey (CPS). Most importantly, the benefit classification scheme based on SIPP data appears to provide reasonably reliable distinctions between retired-worker and widow benefits for widowed women and permits the identification of retired-worker benefits for those women dually entitled to retired-worker and spouse benefits. In addition, the distinction between disabled- and retired-worker benefits for recipients aged 62-64 appears to be reasonably reliable, and for women under age 65, the classification procedure distinguishes between disabled-worker benefits on the one hand and widow and widowed mother benefits on the other. Finally, SIPP procedures for identifying minor child beneficiaries yield markedly better estimates than those available from the Current Population Survey. These improvements in the SIPP context are due entirely to the presence of information not collected in the CPS. The enhancement of the SIPP data set in turn resulted directly from an assessment of earlier work carried out by Projector and Bretz in the CPS context and on extensive research into the nature of Social Security reporting errors in the CPS. The superiority of the SIPP data set is linked principally to the presence of three pieces of information: the Medicare BIC, the direct question on reasons for benefit receipt asked of persons under age 65, and the direct measurement of recipiency and amount of benefits for minor children. Other items of some import include self-reported work disability, retirement status (ever retired from a job), previous marital status for currently married women, age first prevented from working due to a health condition, and Supplemental Security Income misreporting items.(ABSTRACT TRUNCATED AT 400 WORDS)  相似文献
