The separation of powers often makes it difficult to understand who is responsible for legislative outcomes. Both members of Congress and presidents seek to shape perceptions of policy responsibility to their advantage. Yet, the relative size of the president's rhetorical stage gives him disproportionate influence in molding these discussions at critical moments. Given these circumstances, how, when, and why, do presidents claim credit for themselves and attribute credit to members of Congress for legislation? Using an original dataset based upon a content analysis of all presidential signing statements from 1985–2008, we find that presidential strategies to claim and attribute credit for laws are greatly impacted by both political context (approval, divided government, midterm elections, and party power) and bill-specific attributes (appropriations, salience, and veto threats). The theory and results highlight the importance of taking multiple institutions into account when thinking about credit.  相似文献

The US-Mexico border is both a line of potential separation and a span of contact and blending of cultures. National and local perceptions and intentions about this boundary often differ, and the formulation and implementation of border policy is thus subject to many conflicting pressures. Not the least are those generated by government agencies with border responsibilities. Perspectives as local, border, and field offices, combined with inter-agency rivalry and uncertain jurisdictions, lead to border management operations that are inconsistent with apparent national (central) policy, illustrated by the complex bureaucracy present in El Paso—the largest urban site on the border. Proposed solutions cluster around improvement of the existing structure (with better equipment, budgets, or staffing) or reorganization of the primary border agencies. Recent efforts by the federal government to introduce changes based on both of these approaches have been markedly unsuccessful, reflecting a continuing inability to resolve fundamental differences of opinion (both intracentral and central-border) on the goals of border policy.  相似文献

The challenge of environmental thinking is putting extreme stresses on the imagination and techniques of planners, at least in those European countries where ecological issues are being taken seriously. Generally, city or regional planners, and academics as well, are only at the beginning of a necessarily rapid learning curve. It is argued here that a spatial planning approach to guiding environmental change could usefully complement other sectoral or financial instruments, particularly if focused at regional levels. Important dimensions of different approaches are analyzed, including the political economic model, the degree of development and wealth (north‐south variation) and the institutional framework in each country. The progress made so far is examined in case studies of the Netherlands, England and Catalonia. It is suggested that some aspects of the Dutch approach could form a useful basis, if suitably adapted, for regional planning elsewhere. But, above all, much more fundamental thinking on the goals and means of desirable regional transitions will be necessary.  相似文献

After 1975 the main weight of Spanish regional planning passed down to the 17 autonomous communities. This has resulted in very variable territorial planning activity. Since 1980 the Catalan government, the Generalitat, has been preparing a territorial plan for the whole of Catalonia. A draft of the plan was issued for discussion in 1993. The history of the making of the plan is analyzed, before giving an account of the plan's content. The plan received many criticisms and these are described and assessed. In particular, several paradoxes are considered: why has one of the most dynamically distinctive of Spanish autonomous communities, with a great commitment in 1980 to produce a plan, taken so long to complete the exercise? How is it that a centre‐right government has produced a plan with certain clear goals on such a long time‐scale—to 2026? And why has such apparently ambitious planning been criticized so strongly by professionals and authorities to the left of the government?  相似文献

The Australian Labor Party has always been, and remains, a complex entity which encompasses both centralist/national and decentralist/federal interests and values. The common interpretation that the party has been historically ‘frustrated’ by federalism but is now ‘reconciled’ with it thus exaggerates both the frustration and the reconciliation.  相似文献

The Moab Anticline, east‐central Utah, is an exhumed hydrocarbon palaeo‐reservoir which was supplied by hydrocarbons that migrated from the Moab Fault up‐dip towards the crest of the structure beneath the regional seal of the Tidwell mudstone. Iron oxide reduction in porous, high permeability aeolian sandstones records the secondary migration of hydrocarbons, filling of traps against small sealing faults and spill pathways through the Middle Jurassic Entrada Sandstone. Hydrocarbons entered the Entrada Sandstone carrier system from bends and other leak points on the Moab Fault producing discrete zones of reduction that extend for up to 400 m from these leak points. They then migrated in focused stringers, 2–5 m in height, to produce accumulations on the crest of the anticline. Normal faults on the anticline were transient permeability barriers to hydrocarbon migration producing a series of small compartmentalized accumulations. Exsolution of CO2 as local fault seals were breached resulted in calcite cementation on the up‐dip side of faults. Field observations on the distribution of iron oxide reduction and calcite cements within the anticline indicate that the advancing reduction fronts were affected neither by individual slip bands in damage zones around faults nor by small faults with sand: sand juxtapositions. Faults with larger throws produced either sand: mudstone juxtapositions or sand: sand contacts and fault zones with shale smears. Shale‐smeared fault zones provided seals to the reducing fluid which filled the structural traps to spill points.  相似文献

Opportunities to gamble, particularly on electronic gaming machines (EGMs) have been rapidly increasing in Australia during the 1990s. The increase in expenditure on gambling and the related problems have subsequently become a growing concern, particularly in relation to disadvantaged sectors of the population. Given this, the development of a geography of gambling is an important step in understanding the implications of this rapidly expanding industry. This paper addresses this issue at two distinct geographical scales in metropolitan Melbourne and considers the distribution of EGMs in relation to levels of economic well‐being. Findings suggest that patterns evident at the wider Melbourne scale of greater concentration of EGMs in less advantaged regions are also reflected at a local level. These findings are related to the wider issues of accessibility to gambling facilities and problem gambling.  相似文献
