Zwar sind Untersuchungen in den so genannten Entwicklungsländern mit human- oder naturgeographischem Fokus klassischer Gegenstand der Geographie, jedoch ist es dem Fach im Vergleich mit anderen Disziplinen bisher nicht in ausreichendem Maße gelungen, sich als ernst genommener Partner der praktischen Entwicklungszusammenarbeit zu etablieren. Allerdings hat sich in jüngeren Jahren das inhaltliche und methodische Spektrum der modernen geographischen Entwicklungsforschung erheblich erweitert, ebenso haben sich Selbstverständnis und Aufgabenfelder der Entwicklungszusammenarbeit verändert. Darin liegt die Chance, im Dialog zwischen Wissenschaft und Praxis den Beitrag der Geographie zur Entwicklungszusammenarbeit zu stärken. Die nachfolgenden Ausführungen setzen sich einerseits zum Ziel, thesenartig die Felder aufzuzeigen, die aus Sicht des Fachwissenschaftlers entsprechende Anknüpfungsmöglichkeiten und inhaltlichmethodische Potentiale bieten. Andererseits sollen die Bereiche in Forschung und Lehre angesprochen werden, in denen nach wie vor Handlungsbedarf im Dialog zwischen Wissenschaft und Praxis gesehen wird.  相似文献

The Adelaar , a Dutch East-Indiaman outward bound from Middleburg to Batavia, was wrecked on Greian Head, Barra, in Scotland's Outer Hebrides in 1728. Although heavily salvaged at the time, and situated in an extremely dynamic location, the wreck demonstrates that exposed sites can retain meaningful levels of archaeological integrity, and historically valid conclusions can be drawn from them.

Vegetation structure and composition during the pre‐ and early‐European period in Australia is often proposed as a benchmark against which to measure the effects of modern landscape management practices. However, little quantifiable information exists for that historical period. One potential source of information is the land survey record, used in this study to provide estimates of tree densities that existed during the period 1870 to 1900 in part of central New South Wales. Estimates were obtained for 23 parishes in the north Lachlan River valley, between the towns of Condobolin and Tottenham. Densities were calculated from portion corner to nearest tree data obtained from historical survey plans, using the plotless, closest individual method. Densities ranged from 6.0 to 31.4 trees per hectare for parishes with enough data points for reliable calculation. These figures would account for trees of a diameter large enough to be blazed with a survey mark. Any smaller trees would be additional and, although no quantitative data existed for this, qualitative evidence suggested that the figures obtained were more likely to be underestimates due to the presence of such small trees. The study area was predominantly covered by woodlands which varied in density across the landscape, in comparison to the modern landscape where much of the native vegetation has been cleared for agriculture. Although the tree density figures should be considered to be indicative rather than precise, they provide quantifiable historical figures for past conditions in an area where the historical record is otherwise sparse. Such information is valuable for interpreting ecological changes brought about by modern land management.  相似文献

This article considers the incorporation of part of Britain into the Roman empire in the context of globalization theory and world-systems history. Emphasis is placed on the local effects of the expansion of global systems and their impact on the social practices of eating and drinking at a range of settlements in the southeast of Britain in the Iron Age to Roman transition, c. 50 BC–AD 200. Through the analysis of consumption practices via quantitative pottery assemblage data, it is argued that globalization offers a more sophisticated framework to describe change than current archaeological approaches to Romanization and identity. The results show that while much of the populace was subject to a progressively homogenizing supply of food-related pottery vessels, the use of such technologies was negotiated within social practices drawing on the integration of both local and global cultural elements. Such findings highlight the potential of critical applications of globalization theory to conceptualize economic, social, and cultural changes in Roman provincial societies.  相似文献

Introduction: global production networks--debates and challenges   总被引:4,自引:0,他引:4  
Over the last decade-and-a-half, a rich and vibrant literaturehas evolved that attempts to explain how global industries areorganized and governed, and how, in turn, those relationshipsaffect the development and upgrading opportunities of the variousregions and firms involved. Although this is a sprawling multi-disciplinaryfield of endeavour, to date, three key interlinked strands ofresearch can be distinguished:
  • The global commodity chain (GCC)framework, first elaboratedin the volume edited by Gereffiand Korzeniewicz (1994). Initially,stemming from a relativelystructuralist world systems perspective,‘GCC analysisis principally concerned with understandinghow global industriesare organized. It consists of identifyingthe full set of actors(i.e. firms) that are  相似文献

This essay examines the relationship between two black Freemasons in the Gold Coast and New York in the 1930s. Drawing on the correspondence of D. K. Abadu Bentsi and Harry A. Williamson, this essay argues that fraternal voluntary associations operated as sites for the formation of a gendered diasporic identity. In doing so, it suggests that we need to complicate our understanding of diaspora by considering the ways in which the development of diasporic subjectivity and consciousness, as a dynamic process, is inextricably bound up in the formation of class and gender identities and the maintenance of class and gender boundaries.  相似文献

In the last year or so, markedly different claims have been heard within the development community about just how much progress is being made against poverty and inequality in the current period of 'globalization'. This article provides a non-technical overview of the conceptual and methodological issues underlying these conflicting claims. It argues that the dramatically different positions taken in this debate often stem from differences in the concepts and definitions used and differences in data sources and measurement assumptions. These differences are often hidden from view in the debate, but they need to be considered carefully if one is properly to interpret the evidence. The article argues that the best available evidence suggests that, if the rate of progress against absolute poverty in the developing world in the 1990s is maintained, then the Millennium Development Goal of halving the 1990 aggregate poverty rate by 2015 will be achieved on time in the aggregate, though not in all regions. The article concludes with some observations on the implications for policy-oriented debates on globalization and pro-poor growth.  相似文献

Deconstructing clusters: chaotic concept or policy panacea?   总被引:63,自引:0,他引:63  
Over the past decade, there has been growing interest in localindustrial agglomeration and specialization, not only by economicgeographers but also by economists and by policy-makers. Ofthe many ideas and concepts to have emerged from this new-foundfocus, Michael Porter's work on ‘clusters’ has provedby far the most influential. His ‘cluster theory’has become the standard concept in the field, and policy-makersthe world over have seized upon Porter's cluster model as atool for promoting national, regional, and local competitiveness,innovation and growth. But the mere popularity of a constructis by no means a guarantee of its profundity. Seductive thoughthe cluster concept is, there is much about it that is problematic,and the rush to employ ‘cluster ideas’ has run aheadof many fundamental conceptual, theoretical and empirical questions.Our aim is to deconstruct the cluster concept in order to revealand highlight these issues. Our concerns relate to the definitionof the cluster concept, its theorization, its empirics, theclaims made for its benefits and advantages, and its use inpolicy-making. Whilst we do not wish to debunk the cluster ideaoutright, we do argue for a much more cautious and circumspectuse of the notion, especially within a policy context: the clusterconcept should carry a public policy health warning.  相似文献

Following the rapid demise of local coalmining in the 1950s and early 1960s, the former coal towns of the Cessnock area have survived in their newfound dormitory role, with cheap serviced housing acting as a major constraint on out–migration and an incentive for in–migration for low–income householders, mainly engaged in external commuting or outside the workforce. Behavioural responses to widening local job deficits in the early 1960s were reported in this journal (Holmes, 1965). From household surveys and other sources, Holmes examined the interplay between individual, household and locality variables and presented a spectrum of projected future outcomes for localities, according to accessibility, size and service provision, either attached to the Newcastle–Maitland labour market as low–income outer suburbs or experiencing varying rates of decline while providing low–cost welfare housing. While these broad trends have continued over the last 35 years, significant variants, not predictable in 1965 have emerged, notably: the increased residential attractiveness of some small localities; the strengthening of welfare migration, notably from Sydney; the increase in non–workforce households; and, some evidence of emerging socio–economic polarisation in larger towns. In these respects, Cessnock localities can be viewed as a microcosm of wider trends in Australian society, trends which are most fully revealed in disadvantaged metropolitan peripheral localities.  相似文献
