A longitudinal approach to migration behavior makes it possible to identify a sufficient condition for positive associations between rates of in-migration and rates of out-migration in the same regions. The longitudinal approach centers on the intervals of time that individuals spend in a region, and these intervals can be analyzed in terms of probability distributions or the equivalent hazard functions or survivor functions. Differences in the distributions of these intervals between subpopulations whose residence in a region begins with in-migration and subpopulations whose residence begins with other events are sufficient for temporal variations in rates of in-migration to produce variations in out-migration rates in subsequent periods of time. Tests for such differences are performed using data from the National Longitudinal Survey of Youth.  相似文献

Current western aid and development policy aims to promote ‘good governance’ in the third world. Few would deny that competent, open and fair administration is both a worthy aim and a self-evident requirement of development. However, the current orthodoxy clearly illustrates the technicist fallacy, which is implicit in the following quotation from Pope, that the effective administration or ‘management’ of development is essentially a technical or practical matter. This article argues that development is fundamentally a political matter and that it is illusory to conceive of good governance as independent of the forms of politics and type of state which alone can generate, sustain and protect it. For Forms of Government, let fools contest; Whate'er is best administered, is best. (Pope, 1734: Bk 3, lines 303-4).  相似文献

This paper develops a nested family of market interaction models for the general case of spatial or aspatial goods. Market structure effects are identified in the form of intraregional and extraregional competition. The competing destinations and competing central place models are shown to be special cases of the general modeling framework. An empirical example, using survey data collected from Chicago-area Management and Public Relations (SIC 874) firms, illustrates how the family of models may be used to identify market structure.  相似文献

Many Australians would concur with the view of the novelist Tim Winton that we have an ‘almost supernatural fear and hatred’ of sharks. Especially in the wake of fatal attacks by great white sharks (on average once or twice per year), the extent of fascination and fear within the population at large is undeniable. This paper rejects the frequently encountered explanation that this is because we have an ‘instinctual’, ‘hard wired’ and ‘primal fear’ of wild animals that can kill people. Its focus instead is on the contemporary cultural interpretations of great whites and their behaviour which come to the fore when fatal attacks take place.  相似文献

This article examines the role J.A. Smith played in introducing Croce’s conception of history into British philosophy. In particular, it examines his influence on R.G. Collingwood’s incorporation of the Italian idealist conception of history into his own philosophy. The contentions that Smith was a key popularizer of Italian idealist ideas into Britain and that he helped to shape Collingwood’s intellectual developed is not new. Yet these interrelated topics have not been explored in any great depth. Collingwood’s own reticence over his intellectual debt to Smith, a lack of interest in Smith and an unfamiliarity with his philosophy have all contributed to this neglect. This article seeks to redress this neglect through analysing how Smith nurtured Collingwood’s adoption of a Crocean conception of history. To achieve its aim, this article first analyses Smith’s own reception of Croce’s conception of history. From this, it presents a contextualist analysis of Collingwood’s development of a Crocean conception of history and the role Smith played in its adoption. Finally, this article examines why, despite Smith’s influence over his intellectual development, Collingwood failed to acknowledge the intellectual debt he owed to Smith.  相似文献

The establishment of the World Trade Organization (WTO) has been widely accepted as representing the legalisation of world trading rules. However, it is important to reflect on the limits of this legalisation thesis in terms of the interface between international and domestic policy processes. By locating trading disputes in a political analysis of policy implementation, it is argued that it is difficult to establish conceptually how the WTO dispute settlement system could have authority separate from and above the conventional international politics of trade policy relations. Instead, the article argues that case outcomes should be expected to be largely the product of domestic political institutions and policy processes, and how these intersect with developments in the WTO dispute settlement system. Brief studies of the Australian government's dispute settlement strategy and two high-profile WTO disputes—the US upland cotton and European Union sugar cases—serve to suggest that the authority of international trade law is not as significant as assumed by the legalisation thesis. Rather, domestic politics and institutions have an important impact on the outcome of trade disputes.  相似文献
