Recent contributions by geographers on the relationships between states and citizens have documented the rise of rolled‐out neoliberalism. Development agendas are, it is argued, increasingly dominated by the principles of market‐driven reforms, social inequality, and a drive towards enhancing the economic competitiveness of the supply side of the economy. However, at the same time, a parallel set of discourses has emerged in the development literature which argues that it is principles of sustainable development that have, in practice, become dominant. The emphasis is, instead, on democratic empowerment, environmental conservation, and social justice. This paper examines the relationships between these ostensibly very different interpretations of contemporary development with an assessment of one of the Labour government's most ambitious planning agendas—the publication in February 2003 of the document Sustainable Communities: Building for the Future . The proposals are promoted as a "step change" in the planning system with a new emphasis on tackling shortages of housing in the South East and reviving the economy of the Thames Gateway area. The paper assesses the different ways in which such programmes can be interpreted and argues that contemporary development practices in countries such as Britain are constituted by a hybridity of approaches and rationalities and cannot be reduced to simple characterisations of rolled‐out neoliberalism or sustainable development.  相似文献

Abstract.  Using German district data we estimate the structural parameters of a new economic geography model as developed by Helpman (1998) and Hanson (1998 , 2001a ). The advantage of the Helpman‐Hanson model is that it incorporates the fact that agglomeration of economic activity increases the prices of local (nontradable) services, like housing. This model thereby provides an intuitively appealing spreading force that allows for less extreme agglomeration patterns than predicted by the bulk of new economic geography models. Generalizing the Helpman‐Hanson model, we also analyze the implications for the spatial distribution of wages once the assumption of real wage equalization is dropped. If we no longer assume real wage equalization we find support for a spatial wage structure as well as for the relevance of the structural parameters of the theoretical model.  相似文献

This paper presents a multi‐criteria analysis of Canadian electricity supply futures. Based on the results of Natural Resources Canada's Energy Technology Futures Project, a panel of energy and environmental experts was selected to evaluate alternative electricity supply futures according to several competing environmental, social and economic criteria. Electricity supply futures are explored from both sectoral and regional perspectives and the sensitivity of supply preferences examined in regard to changing electricity environment conditions. The results indicate a demonstrated preference for national electricity supply diversification, including improvements in fossil‐fueled electrical generation technologies and significant increases in the integration of renewable electricity sources. At the regional level, however, the analysis suggests significant dissent amongst provinces with regard to the nature of electricity diversification and future growth opportunities based on regional electricity resource siting.  相似文献

This paper highlights the importance of organising workers in the low‐paid services sector if British trade unions are to secure themselves for the future. After outlining the scale of the challenge and the new efforts being made to promote organising by unions, the paper looks at the hotel industry in more depth. A case study of a union campaign to win union recognition at the Dorchester Hotel in London is used to highlight the limitations of workplace‐focused campaigns in this sector. Drawing on the lessons of experience in North America, the paper then argues that an extra ‐workplace, occupational and/or sectoral approach may well secure better results. In so doing, workplace issues could be recast as matters of economic and social injustice, widening the scale of any campaign.  相似文献

Women constitute a disproportionate 80 percent of people diagnosed with environmental illness (EI), a contentious condition in which patients react adversely to everyday chemicals in the environment at levels politically conceived to be 'safe'. Whilst the diverse range of somatic symptoms constitutes a biomedical anomaly, in this paper I present an alternative means of conceiving environmentally ill bodies. Women (and environmental health practitioners at the Environmental Health Centre, Nova Scotia) have begun to view their bodies as complex systems that have been nudged into a state of 'corporeal chaos', in which minute quantities of chemicals trigger disproportionate somatic symptoms. This chaos extends into 'corporeal space'[ Moss and Dyck (1999a) ] as the diagnosis of environmental illness is experienced simultaneously through both material and discursive bodies. This diagnosis also carries with it a means to mitigate corporeal chaos through a series of body‐ and environment‐based modifications that replace risky bodies with 'safe space'. As a discursive construct, safe space is associated with an absence of chemicals, and in order to mitigate chaos, should ideally be stable, predictable, controllable and communicative. I finalise this paper with some examples of body modifications and illustrate how safe space materialises in the home environment .  相似文献

Formalist theories of knowledge that underpin GIS scholarship on integration neglect the importance and creativity of end‐users in knowledge construction. This has practical consequences for the success of large distributed databases that contribute to spatial‐data infrastructures. Spatial‐data infrastructures depend on participation at local levels, such as counties and watersheds, and they must be developed to support feedback from local users. Looking carefully at the work of scientists in a watershed in Puget Sound, Washington, USA during the salmon crisis reveals that the work of these end‐users articulates different worlds of knowledge. This view of the user is consonant with recent work in science and technology studies and research into computer‐supported cooperative work. GIS theory will be enhanced when it makes room for these users and supports their practical work .  相似文献

Although environmental assessment (EA) has been applied to large resource and infrastructure projects in developing countries, recent innovations in EA concepts, processes and tools have facilitated its application to small projects focused on basic human and livelihood needs. This paper describes innovations in the application of EA to community projects implemented by Canadian nongovernment organizations and their partners in sub‐Saharan Africa. Innovations include: (1) the dovetailing of environmental constructs in neopopulism with a conceptual shift in EA toward participatory, transactive planning; (2) assessment methodologies adapted from participatory rural appraisal; (3) development of grassroots EA capacity; and (4) linkage of community EA with project planning. Community EA is demonstrated for five cases involving agriculture and charcoal retail in Uganda, water supply and flood control in Niger and integrated rural development in Zambia. Future prospects and challenges include cultural adaptation, community empowerment through realignment of power relationships, mutual development of local and national EA capacity and increased training and resources for enhancing grassroots EA capacity .  相似文献

Conventional thinking about war is encumbered by an inappropriate geographic paradigm that conceptualizes "targets" in terms of fixed latitudinal/longitudinal locations. This paper reconceptualizes terms such as "war" and "targets" to recognize intangible problems and develop appropriate counter‐terrorist strategies. This requires geographic inquiry focused on spatiality, not on location. We frame our discussion about terrorist networks (Al‐Qaeda in particular) in terms of understanding a network's sense of place and sense of space . The former "places" a network's meeting and recruiting grounds; the latter clarifies the operational dynamics of a network across space, at different scales, from the body to the neighborhood, to the region, and across nations. We argue that the roots of terrorism lie in conditions of disenfranchisement in particular types of places, understanding, however, that the socio‐cultural fabric of a terrorist network such as Al‐Qaeda evolves across space as well as time. Counter‐terrorist strategies should target neither people nor places but rather the conditions that give rise to terrorism; further, "intelligence" should focus on network dynamics, beyond particular people in particular places. We draw from network theories (specifically actor network theory and network approaches in economic sociology) to unravel network dynamics, and we draw from the literature on spatiality to interpret such dynamics in space, over time. We advocate a non‐military engagement with terrorism on both moral and strategic grounds; here we focus on the strategic dimension, the value of which has received scant attention.  相似文献

Abstract.  Population and employment in the 50 United States are found to be non‐stationary and cointegrated. Vector error correction (VEC) models exhibit dynamics with adjustment to shocks essentially completed in 30–35 years . This contrasts with adjustment periods between one and two centuries for non‐stationary models specified in levels. These dynamic adjustment patterns support the hypothesis that relatively long adjustment periods and slow dynamics are probably the spurious results of using non‐stationary levels of population and employment outside of a VEC model framework. Recommendations for modeling the population–employment relationship are offered based on the findings reported.  相似文献

Ghosh's ‘supply-driven’ input-output model is a well-known alternative for Leontief's traditional ‘demand-driven’ input-output model. The Ghosh model calculates changes in gross sectoral outputs for exogenously specified changes in the sectoral inputs of primary factors. Typically, the model is interpreted so as to describe physical output changes as caused by changes in the physical inputs of primary factors. It has been convincingly argued, however, that this interpretation in terms of quantities is implausible. In the present paper it is shown that the supply-driven input-output model becomes plausible, once it is interpreted as a price model. That is, sectoral output values change due to price changes, which are caused by price changes for the primary inputs. Therefore the term Ghosh price model is adopted for the supply-driven model, whereas the demand-driven model is referred to as the Leontief quantity model. Dual to this Leontief quantity model is the standard Leontief price model. It is shown that the results obtained by the two price models are equivalent. Interpreting the supply-driven input-output model as a price model also allows for a meaningful interpretation of the inverse matrix in terms of multipliers. As the dual to the supply-driven (or Ghosh price) model the Ghosh quantity model is derived, which is equivalent to the demand-driven (or Leontief quantity) model.  相似文献

This paper aims to disentangle patterns of aid, trade, conflict and migration between Canada and Sri Lanka, illustrating the surprisingly significant traffic between the two countries and exploring the significance and quality of these connections. International aid to Sri Lanka is closely related to the opening of markets to multinational investment beginning in 1977. This economic liberalisation overlaps with periods of conflict in Sri Lanka and of macroeconomic growth. The prosperity it has generated, however, has not benefited all social classes and ethnic groups. Accordingly, conflict in Sri Lanka has been characterised by uprisings led by unemployed youth, peaceful and violent protests of discrimination against Sri Lankan Tamils and militarised government reprisals to both. A long period of macroeconomic growth ended in the final quarter of 2001, after the bombing of commercial airliners at Sri Lanka's international airport. Geopolitical and geoeconomic conditions in Sri Lanka changed dramatically. In this context, Canada's International Development Agency (CIDA) and other aid agencies aspire to 'correct for conflict' and promote a democratic and peaceful Sri Lanka through peace‐building and other aid measures. Militarised conflict over at least the past 20 years has generated massive human displacement both within and beyond the country's borders, spawning international migrants in search of asylum. In 1999, Sri Lanka was the leading source country of refugee claimants to Canada. Canada hosts the single largest Sri Lankan diaspora of any country. By examining the nexus of economic liberalisation and aid, I analyse its relation to conflict in Sri Lanka and migration to Canada .  相似文献

The social implications of GIS have been debated over the past five years among scholars in several disciplines. GIS have been either conceived by practitioners as value‐free, neutral tools for problem‐solving or castigated by critical social theorists as socially biased technologies serving only corporate and state interests. Neither of these polarized views is very helpful in understanding the complex relationship between GIS and society. This paper argues that GIS are increasingly becoming media for communicating various crucial social and environmental information to the general public. By reconceptualizing GIS as media, the paper conducts a detailed tetradic analysis on the social implications of GIS using Marshall McLuhan's law of media. The analysis reveals the paradoxical and ambivalent nature of GIS technology. To make GIS fulfill democratic ideals in society, this paper calls for a shift of perspective, from viewing them as instruments for problem‐solving to viewing them as media for communication. This shift from instrumental to communicative rationality enables us to examine more critically and holistically how space, people and environment have been represented, manipulated and visualized in GIS and thus promotes a more critical and democratic GIS practice .  相似文献

Abstract.  We investigate the ( r ∣ X p )‐medianoid problem for networks. This is a competitive location problem that consists of determining the locations of r facilities belonging to a firm in order to maximize its market share in a space where a competitor is already operating with p facilities. We consider six scenarios resulting from the combination of three customer choice rules (binary, partially binary, and proportional) with two types of services (essential and unessential).
Known discretization results about the existence of a solution for the set of nodes are extended. Some examples and computational experience using heuristic algorithms are presented.  相似文献

There has been growing interest in the prospects for a new trade union internationalism in recent years, following the end of the Cold War and the coming together of the main national union organisations into one confederation, the International Confederation of Free Trade Unions (ICFTU). For the first time in decades, geopolitical straitjackets and defensive nationalistic postures are giving way to more open, internationalist perspectives as unions attempt to get to grips with global capitalism. However, despite some well‐publicised grassroots globalisation campaigns, effective international labour organising and networking remains thin on the ground. One of the reasons for this is that, despite the rhetoric of globalisation and the reality of multi‐layered governance, the "national" space remains the critical scale at which unions operate. Variations in both union organisation and the politico‐institutional context within which unions operate nationally continue to shape international solidarity activities. This theme is pursued in this paper through the contrasting cases of the UK and Norwegian trade union movements. Although both union movements have been subject to similar problems in recent years, in terms of membership decline and the pressures of increasing global economic integration, the different national political and economic contexts within which unions are embedded have been important in facilitating or constraining international strategies.  相似文献

The concept of path dependence is central to the current discourse on evolutionary approaches in regional transformations. Along the subtropical coastlands of eastern Australia, low‐input, low‐income, and labour‐intensive dairy farms were subject to prolonged dysfunction. Their creation and entrenchment serve as a potent case study of path dependence and lock‐in that were driven by mutually reinforcing attributes—behavioural, socio‐economic, cultural, political, and infrastructural. Functional rigidification and incipient dissolution were scrutinised in farm surveys undertaken from 1952 to 1954 in the Moruya and Copmanhurst districts of coastal New South Wales. At both locales, the dairy industry comprised a core of long‐term stable producers located mainly on the more accessible and productive alluvial soils, together with a fluctuating number of marginal producers motivated by a variable mix of personal, locational, and temporal influences. The demise of dairying was prolonged, in part by the industry's exceptional survival capabilities and in part by the lack of any viable alternative farming staple. The belated collapse of dairy farming in the 1960s and 1970s has facilitated the emergence and lock‐in of an alternative multifunctional pathway, driven primarily by consumption with subordinate production and protection values. The two case studies reveal synergies between the closely aligned path dependence and the multifunctional trajectory/transition concepts in yielding insights into the dynamics of rural change and in offering guidelines for further research within evolutionary economic geography.  相似文献

The purpose of this article is to suggest: (1) That a particular model of writing African church history inherited from the historiography of European mission has influenced the way in which the trans-African history of Christianity in Africa has been presented. It is argued that this model has encouraged an episodic view of the Christian past, through its documentary emphasis on the last two centuries. (2) That this model was both implicit and unchallenged in the theological trends of the post-colonial period, with their programmatic emphasis on indigenization and inculturation. The work of the vast majority of African theologians, and hence of church historians outside Africa, envisaged a model of the 'discontinuous past' premised on the idea that Christianity was to be understood in terms of export and import or 'early' north African and 'later' southern African engagement. This model is here labelled the 'discontinuity paradigm'. (3) That a new model for the writing of church history in Africa should be attempted. An 'adaptive similarities' model is proposed which sees the history of the church in Africa against the template of analogous conversion–adaptation–fissiparation movements in the earlier periods of the church's existence. The essay proposes a pan-African church history 'project' which focuses its work on constructing this model from regional church history efforts (Sundkler) and which attempts to isolate the recurrent themes and patterns of African Christianity (the thematic–chonological matrix) as interpreted within the wider African context (the geographical–cultural matrix).  相似文献

Drawing on an interview‐based case study of young people caring for dependent adult members of their households in Harare, this paper connects the experiences of young carers in Zimbabwe to global forces—namely the HIV/AIDS pandemic and economic liberalisation. It is argued, firstly, that care‐giving by young people is a largely hidden and unappreciated aspect of national economies which is growing as an outcome of conservative macroeconomic policies and the HIV/AIDS explosion. Secondly, that young people have a right to recognition of their work as work. Thirdly, while acknowledging that conceptualising childhood is problematic, there needs to be less emphasis on northern myths of childhood as a time of play and innocence and more attention on defending children's rights to work as well as to be supported in their work under appropriate circumstances. The articulation between global processes and the localised experiences of individual children as providers of care within the home contributes to efforts to re‐introduce social reproduction as an important (but often missing) aspect of debates around globalisation. In addition, this article adds to the growing literature on the geographies of childhood while tackling the imbalance within that literature, whereby working young people and those of the global South are relatively neglected. Suggestions are offered in the conclusions for policy recommendations to recognise and support young carers in Africa, while calling for further research.  相似文献

Mathematical modelling has suggested that Levallois core morphology represents a reduction strategy driven by economic considerations; particularly the minimization of ‘waste’ while aiming to maximize cutting edge length of flakes obtained from cores of a given size. Such models are elegant in that they facilitate formal modelling of economic considerations that potentially motivate patterns seen in prehistoric data. However, the abstract nature of such models means that they do not take full account of all the practical difficulties and material challenges involved in reproducing Levallois-style reductions in stone. In particular, such models have only examined nodule morphology in two-dimensions, and did not take account of the fact that in the case of classic (lineal) Levallois reduction, core surfaces must be re-prepared between successive stages of flake removal. Hence, the potential economic implications of these factors are currently unknown, potentially undermining the significance of models that assume specific economic conditions. Here, we undertook to examine these factors using a series of experimentally produced Levallois reduction sequences. A total of 3957 flaking events were considered in our analyses, and we used six specific measures of economy to examine Levallois reduction across successive phases. Our analyses found that key assumptions of mathematical models suggesting that Levallois core morphology was driven by economic considerations (i.e. conservation of raw material when attempting to remove flakes with long cutting edges) can be upheld under the practical challenges of replicating Levallois-style reduction in stone. In supporting the notion that Levallois reduction has advantageous economic properties, our results emphasize the importance of considering why Levallois reduction did not emerge earlier in the archaeological record, and indeed, why even during the later Pleistocene the temporal and geographic distribution of Levallois technology varies. Our results also re-emphasize the value of formally modelling lithic reduction strategies in specific economic terms.  相似文献

Consideration of aesthetic values in resource and environmental management in North America emerged in the 1960s. It soon became enshrined as 'visual resource management', which emphasized a singular visual notion of aesthetics and an expert‐based approach to assessment. This paper challenges this dominant view. An empirical research study is presented in which a broader conceptualization of the landscape aesthetic and a participatory methodology for assessment were developed and used to explore the landscape experiences of inhabitants of the Cariboo region of British Columbia. Themes, categories and ideas of landscape experience grounded in participant perspectives revealed a richness of landscape and can be seen as an opportunity to supplement and enrich current landscape assessment and 'visual' management. More importantly, this conceptual and methodological reorientation in understanding landscape aesthetic sensibilities both reflects and supports the shift in current thinking within resource and environmental management more generally, from technocratic, state‐centred, expert‐based approaches to locally responsive (place‐based), participatory and inclusive approaches for dealing with environmental concerns and resource‐development issues .  相似文献

Sedentism is a commonly used concept in settlement pattern analysis. In a recent review of this concept Rafferty (1985) found “sedentary” to be related to both settlement permanence and site size. Both space and time are fundamental aspects of sedentism. While maintaining permanence as a central factor, this paper discusses further aspects of sedentism primarily in relation to the use and meaning of space. A case study based on archaeological and historical materials on Sami and Norwegian settlements in arctic Norway is used as an illustration. In arctic Norway prehistoric maritime settlements have often been interpreted as being either transhumant or sedentary. The prehistoric case of sedentism is then viewed in relation to the historically known differences in settlement permanence in space and time for Norwegian and Sami populations in the same area of arctic Norway. It is proposed that models of sedentism should not only be based on ecological, economic, and adaptational considerations but should also include the importance of the meaning of place in the relationship between human populations and landscape.  相似文献
