The devolution and regionalisation of political and administrative structures following the election of New Labour in 1997 have changed the nature of the state and territorial development and governance in the UK. A regional and sub-national tier has opened up within the existing multi-layered governance system operating at the supra-national, national and local scales. This ‘new institutional space’ is increasingly open to the participation of social institutions--including trade unions--in economic and social governance. Drawing upon empirical analysis of the experience of the Northern Trade Union Congress (NTUC) in the North East region of England, the paper argues that the NTUC--in contrast to its national organisation--is beginning to engage with the emergent institutional structures but its role is inhibited by the centralised strategy and structure of the TUC nationally, its own need for upgrading, capacity building and greater financial resources and the interaction between the North East’s particular legacy of tripartite corporatism and the more pluralist modes of regional development governance emerging in the English regions. Unless such issues are addressed regional trade union centres--such as the NTUC--risk remaining relatively junior partners in the emergent regional governance structures.  相似文献

The aquifer system of the Basin of Mexico is the main source of water supply to the Mexico City Metropolitan Zone. Management of the Basin’s water resources requires improved understanding of regional groundwater flow patterns, for which large amounts of data are required. The current study analyses the regional dynamics of the potentiometric groundwater level using a new database called the Basin of Mexico Hydrogeological Database (BMHDB). To foster the development of a regional view of the aquifer system, data on climatological, borehole and runoff variables are part of the BMHDB. The structure and development of the BMHDB are briefly explained and then the database is used to analyze the consequences of groundwater extraction on the aquifer’s confinement conditions using lithology data. The regional analysis shows that the largest drawdown rates are located north of Mexico City, in Ecatepec (a region that has not yet received attention in hydrogeological studies), due to wells that were drilled as a temporary solution to Mexico City’s water-supply problem. It is evident that the aquifer has changed from a confined to an unconfined condition in some areas, a factor that is responsible for the large subsidence rates (40 cm/year) in some regions.  相似文献

The paper examines the prospects for resource-based development in the Russian Far East. It adopts a critical perspective on the potential for resource-based development by examining problems with Far East resource industries, specifically by looking at the experience of the other resource economies more generally. In particular, it highlights the new geo-economic context for resource development in the Far East of Russia as the world economy approaches the much touted, and now questioned, ‘Pacific Century’.  相似文献

There is currently a lively discussion on the role of historic memories and the re-visiting of historic legacies in post-communist countries. Using the example of Poland and its legacy of the tripartite division of the 19th century, this paper aims to illustrate how symbolic conflicts over identity politics and the interpretation of history may critically influence discourses on the debates on, and portrayals of, variations in regional development. The paper thus discusses the post-war history of Poland in the context of the so-called left-right political cleavage, and the varying related debates on the ‘quality’ of regional development as part of Poland’s post-communist restructuring. These discussions include varying projections of the nature and role of social capital and its relative ‘usefulness’ for a successful development Poland’s after communism. And there are clear political overtones to these contrasting portrayals of Poland’s history and its regionally varying legacy. Drawing on different definitions of the notion of social capital, the paper then discusses how different legacies, such as an introspective and extrovert outlook of population and institutions, and the degree of cohesion among them, circumscribes a region’s economic development prospects.  相似文献

Spatial and planning policies in Britain have increasingly become focused on regional inequalities and the creation of mixed, sustainable and balanced communities. Within these new policy paradigms the category of the key workers has emerged as an essential element in the socio-economic sustainability of any bounded area programmes have been introduced to support their needs. Yet, defining key workers is an inherently political process as it necessitates the selection of essential and non-essential workers. Theoretical approaches that highlight state selectivity and the ways in which key policy subjects and objects are identified and mobilised have become increasingly popular across the social sciences and key worker support programmes provide a clear example of these processes in action. This paper draws on archival research to explore the formation of the category ‘key’ worker as an object of government in spatial development policies of the post-war period. It examines how key worker programmes were established to tackle the economic problems of Development Areas. It argues that definitions of key workers were forged in and through particular social, political, and economic contexts and that their emergence as an object of government presupposed and reinforced the existence of different classes of workers and different types of citizens. The paper highlights the significance of such historical work in assessments of contemporary policy and academic debates concerning the changing character of sustainable communities and citizenship, regional development, and changing modes of state regulation.  相似文献

The paper examines criminality as one of the second order consequences of development which the society has been struggling off for so long. In the study area, Kwara State of Nigeria, positive associations between development and criminality have begun to manifest themselves. The highest positive associations are between criminality and urbanization, telephone and motor vehicles respectively, while the lowest associations are with industrialization, electricity and education. In order to reduce criminality without holding down development in the state, various suggestions have been made. Central measures include more equitable distribution of criminality, strengthening of the police force and free mobilization of policemen from high crime areas to low crime areas. Long term measures include improving the socio-economic wellbeing of the general populace with special reference to the provision of modern industries, education, electricity, water and roads to rural dwellers and thereby curbing the wave of rural-urban migration and its attendant social ills. This should be accompanied by unqualified deep-rooted revolution in the monstrously unjust socio-economic system we currently operate, for afterall, as Peet (1975) rightly observed crime is a surface expression of discontents which lie deeply embedded in the social system.  相似文献

Agri-environmental policies and planning influence agricultural landscape management, and thus the capacity to deliver landscape services and to contribute to rural viability. Numerous models and frameworks have been developed to improve comprehension of the mechanisms and interrelationships between policies, landscape and socio-economic values and benefits. As social-ecological systems, landscapes are closely depending from the socio-institutional and territorial context of the specific rural locality. The paper proposes an enhanced framework for assessing these mechanisms by acknowledging the critical role of the regional macro-environment. A literature review and the revisiting of evidence from eight European case studies are applied to establish a comprehensive understanding and exemplification of the links between the policies, landscape, ecosystem services and value flows. Results highlight the need for integrative, inter- and transdisciplinary research approaches. Efficient landscape policies require enhanced regional embeddedness and targeting, acknowledgement of user demands and the capability of regional community and governance structures for policy implementation and natural capital valorisation.  相似文献

Spectacular growth has marked the industry initiated by Malcolm McLean with the sailing of the Ideal-X in 1956. While the growth of container shipping has been typically seen in terms of technological advances, increasing vessel capacity, traffic growth, financial performance and competitiveness, it has been shaped also by organisational transformations. This paper provides an overview of the major companies that make up the container shipping industry, tracing the rapid adoption of containerisation by American carriers to its diffusion to Europe and then Asia. While several carriers belong to business conglomerates, the most dynamic in recent years have been those that are those that possess a family structure. About 12 of the present top 20 carriers are largely family controlled, including 4 out of the top 5. Unlike other capital intensive industries, where the power has shifted towards corporate governance, the container shipping industry retains a strong individualistic entrepreneurial character. At a time when North American ownership in container shipping is no more, the spirit of innovation began 50 years ago by an American visionary is still evident in the entrepreneurial dynamism of many of the industry leaders.  相似文献

This paper focuses on sustainability appraisal as a key technique for pursuing the political goal of ‘sustainable development’ within English planning. We conclude that unlike many planning tools of the past which have sought to depoliticise decision making by using more ‘scientific’ techniques, the early experience of sustainability appraisal has instead repoliticised them, by highlighting where tensions exist but without providing solutions.  相似文献

Su-Xi-Chang area and the city of Shanghai, located in the south of Yangtze Delta, China, has subsided due to groundwater overpumping. Because of the regional scale of the groundwater exploitation, cone of depression and land subsidence at present, Su-Xi-Chang area and Shanghai are treated as a single area for a land subsidence study, which could more clearly elaborate the relationships between the deformation features of hydrostratigraphic units and the different sites of the cone of depression. All hydrostratigraphic units in the study area were discussed throughout. Based on the field data, including data on compression of individual strata from groups of extensometers and groundwater levels from observation wells, the relationship between the deformation and the groundwater level was analyzed. The results indicate that the deformation features of the hydrogeologic units are greatly related to hydrogeologic properties and groundwater-level variations. An identical hydrogeologic unit may exhibit different deformation features in different locations such as along the periphery and in the center of the cone of depression. In addition, in the same location, a hydrogeologic unit also exhibits different features in different periods because of different groundwater level variations. The delay phenomenon of the sandy aquifer is not specific but occurs widely.  相似文献

A flume study on the development and equilibrium morphology of current ripples in fine sand (D50 = 0·238 mm) was performed to extend an empirical model for current ripple stability in 0·095 mm sand to larger grain sizes. The results of the flume experiments agree with the very fine sand model that current ripple development from a flat bed is largely independent of flow velocity. At all flow velocities, ripples evolve from incipient, through straight, sinuous and non-equilibrium linguoid, to equilibrium linguoid plan morphology. The time needed to achieve an equilibrium linguoid plan form is related to an inverse power of flow velocity and ranges from several minutes to more than hundreds of hours. Average equilibrium height and length are 17·0 mm and 141·1 mm respectively. These values are about 20% larger than in very fine sand. Equilibrium ripple height and length are proportional to flow velocity near the stability field of dunes. In the same velocity range, a characteristic grouping of ripples with smaller ripples migrating on the upstream face of larger ripples was observed. Bed-form development shows a conspicuous two-phase behaviour at flow velocities < 0·49 m s?1. In the first phase of development, ripple height and length increase along an exponential path, similar to that at higher flow velocities, thus reaching intermediate equilibrium values of 14·8 mm and 124·5 mm respectively. After some time, however, a second phase commences, that involves a rapid increase in bed-form size to the typical equilibrium values for 0·238 mm sand. A comparison with literature data shows that the results obtained for 0·238 mm sand agree reasonably well with other flume studies at similar grain size. Yet considerable variability in the relationships between ripple dimensions and flow strength ensues from, among others, underestimation of equilibrium time, shallow flow depths and differences in sediment texture.  相似文献

Two land development scenarios based on the Central Florida Regional Growth Vision projection for 2050 were used to explore the developments?? potential influence on regional climate. One scenario is a widespread suburban land development plan, and the other is a higher density urban development plan, both for the same location in central Florida. A series of simulation experiments were conducted using a regional climate model upgraded for this study to include an urban scheme. Noticeable differences in simulated regional climate patterns were found between the land development scenarios, which could potentially influence population requirements for energy and water. In our simulations, the aggregated effect of land cover changes over large suburban areas produced a more intense heat island effect than that produced by high-density urban areas.  相似文献

Local economic development policies have surged in Brazil over the past decade—a major shift in this regionally diverse country of 27 states, over 5000 municipalities, and the largest economy in Latin America. We review the stylized facts, expected patterns and policy recommendations from the foundational studies in regional and urban economics. We then provide a summary of a more recent stream of scholarship focused on local economic development (LED) studies in developed and developing countries that have surged in the last 20 years. Based on this review, we then systemize the findings emerging from studies focused on analyzing local economic development policies in Brazil recognizing the distinctive contributions emerging from both the empirical and the case studies literatures. We identify key lessons for (and from) the Brazilian experience and conclude that Brazil and Latin American countries need a new generation of studies that undertake more rigorous evaluations of these policy experiments. Finally, we recommend steps to advance such research.  相似文献

The role of power in economic activity has been researched across the social sciences but there has been little engagement with the spatialities of power relations. This paper thus draws on a recent reinvigorated interest in power within economic geography to develop an approach for understanding how the spatiality of power relations in economic practices are constituted through different forms of proximity. It argues that proximity needs to be conceptualised as multi-dimensional including physical, cultural, virtual and organizational proximity between firms and actors. It further contends that the development of different forms of proximity shape the agency of empowered actors in industry clusters and regional economies. This general proposition is explored by presenting research into a case study: the UK-based private equity industry. The research focuses on the nature, role and development of different forms of proximity between private equity firms and the investee firms that are the subject of investments.  相似文献
