Global scale longitudinal gradients of pressure in the plasmasphere may be formed naturally by ionospheric processes, or caused by electrostatic fields of ionospheric dynamo origin. It is shown that plasmaspheric gradients of pressure, orthogonal both to the magnetic field (B) and to grad B, generate geophysically significant field-aligned currents. Considering the ionosphere and plasmasphere as a coupled electrodynamic system, these currents alter non-negligibly the self-consistent ionospheric electric field and current. Criteria are established for this coupling mechanism (a kind of plasmaspheric impedance) to be significant. This has implications for the relationships of ionospheric electric fields and currents, F-region drifts, and magnetic variations, due to upper atmosphere tides and winds.  相似文献

Urban policy in Britain has long been characterised by circumscribed and fluctuating institutional structures of community involvement. From the Community Development Programmes of the early 1970s to the assertive neo-liberalism of the 1980s and back to the partnership based politics of the 1990s, community involvement in the construction and delivery of urban policy has been a critical theme. The new administration, with its emphasis on the ‘stakeholder’ society seems set to continue the trends of the 1990s by promoting the concept of partnership as something of a panacea for the difficulties and exclusionary politics that have dogged urban policy programmes. Consequently, a vital area of study into the next century concerns the form that local democratic structures will take and the relative levels and distribution of risk and reward that regeneration schemes create for different sections of local communities.Drawing on material from Cardiff, this paper examines the construction of local political relations in the new urban governance and addresses the issue of community involvement in the politics of local economic regeneration. In particular, it focuses on a small business association which emerged in the wake of the major regeneration programmes being undertaken by the Cardiff Bay Development Corporation (CBDC), a powerful quango established by central government in the late 1980s. The study demonstrates how the association, which consisted of local businesses, tried to influence the local regeneration programmes and how its ‘pro-growth’ stance was actively used by the CBDC to legitimate its own policies in the face of wider criticisms from local residential groups. The paper looks at the difficulties of constructing local community participation and concludes that voluntarist, top-down partnership structures in existing policy may only serve to legitimate and implement policy decisions taken by powerful non locally-accountable regeneration agencies.  相似文献

Cultural policies have existed as a structural element of the Nordic welfare states from the very beginning. Today these policies are being re‐evaluated, and there are some indications that they may be gradually dismantled. Local cultural politicians in municipalities (cultural boards) and professionals (e.g. cultural secretaries) have become uncertain and anxious about their future role and legitimacy.

This new situation is addressed and analysed by using the ideas of Goffman's on‐and off‐stage representations, and Foucault's governmentality. Important background factors in the development of cultural policies both in the past, present and future are identified and used to explain the present unclear situation as a reflection of an existing cultural hierarchy or hegemony (see Gramsci). This paper also discusses the role of cultural professionals and local cultural politicians in the implementation of the Nordic cultural policies with references to examples from Finland and Sweden.  相似文献

Steatite has been one of the most difficult materials of archaeological interest to characterise by physico-chemical methods of analysis with a view to identifying its origin. This paper presents a new protocol for the chemical characterisation of steatite based on the analysis by ICP-MS in tandem with INAA of rare earth elements (REE) and some transition metals in geological steatite from several outcrops on the Shetland Islands and on Crete. The major advance over earlier work has been the secure determination of REE at low concentrations. The results have demonstrated the ability to discriminate chemically three of the known Viking Age sources on Shetland. On Crete, although the situation is complex, four sources in the centre of the island have been partially differentiated. This study has also shown that first mineralogical analysis (by XRD) of steatite provides valuable supplementary characterisation data, and second strontium isotope analysis has promising potential for the sourcing of steatite.  相似文献

China’s declared foreign policy of ‘non-interference’ is contradicted by its actions in recent times. Beyond activities in the East and South China Seas, the involvement of China in negotiations on the Korean Peninsula, the evacuation of Chinese citizens from various crises, and the deployment of Chinese combat troops to peacekeeping missions in Africa have indicated China’s growing interests in the shape of world affairs, coinciding with a growing economic and military capacity to influence them. Much attention has been given to the potential consequences of great-power competition between the USA and China, but little focus has been given to the impact these trends may have in the outlying regions of Chinese foreign policy. One such place is Melanesia in the South Pacific—a subregion where a small influence from a Chinese perspective can have a significant impact on Pacific Island Countries. This article postulates that, over time, there is potential for the consequences of Chinese interests to lead to accidental friction, and suggests that this risk can be mitigated through increased cooperation.  相似文献

In the past 20 years, feminist geographers have gone to great lengths to complicate notions of ‘the field’ and make clear that the field is not an easily bounded space. This body of work has demonstrated the complexity of field spaces, explored ways to destabilize boundaries, and traced the power relations between researchers and participants. Ultimately, this work takes the breaking down of boundaries as an inherent good in field research, and, subsequently, little work has focused explicitly on the utility of physical and emotional boundaries that develop in field research. Our experiences as feminist geographers who reside in our fields show there is much left to understand and subsequently disrupt regarding the boundaries of ‘the field.’ In this article, we build on the concept of ‘intimate insiders’ to discuss the complex negotiation of doing research in the places where we have created personal lives and our sense of community. We often found ourselves struggling to define the physical and emotional boundaries of ‘the field’ on the outside for the sake of our participants and ourselves. In this article, we reflect on boundary-making as a specific feminist methodological practice for addressing the complexity of fieldwork. We discuss the techniques and strategies we used for conducting research in the communities in which we are long-term community residents. In the tradition of feminist methodology, we draw from our research experiences in State College and Philadelphia, Pennsylvania, to reconsider how producing distance through boundary-making has the potential to benefit our participants, our projects, and ourselves.  相似文献

Far‐right parties are on the rise across Europe. Their shared populist rhetoric, emphasis on sovereignty and policies that promote a ‘national preference’ has facilitated the term ‘the new nationalism’. According to an emerging consensus, this new nationalism is primarily a demand‐side phenomenon triggered by cultural grievances, i.e. a cultural backlash, driven by those on the wrong end of a new transnational cleavage. This explanation we argue tends to overlook important variations across countries and across time. As such, in this article, we contest the view that the ‘new nationalism’ is a linear and coherent phenomenon best understood as a cultural backlash. Specifically, our argument is threefold: (1) it is important to conceptually distinguish between populism, nationalism and the far right in order to draw meaningful conclusions about the extent to which this phenomenon is linear, coherent and comparable across cases; (2) voters' economic concerns remain pivotal within the context of the transnational cleavage, entailing that voting behaviour is structured by two dimensions of contestation; (3) the explanatory power of nationalism is in the supply, i.e. the ways in which parties use nationalism strategically in an attempt to broaden their appeal.  相似文献

Abstract

The aim of this article is to analyze the language used by the major actors in contemporary Italian politics. After a brief introduction, which lists the general questions posed by such an analysis, we examine the language of the pre‐1992 regime, which has been rather too hastily condemned as obscure and solipsistic. We then pass to the self‐consciously simple language of Bossi, who constructs a discourse of protest, and of Berlusconi, who offers a discourse of government. These lead to the very different, albeit sometimes complementary, languages of Prodi and D'Alema, which go beyond populism and open new political perspectives. Through these and other examples we examine the role of political language in a changing Italy.  相似文献

From a sociological point of view the early Christian communities seem to have been rather isolated in their pagan, or Jewish, surroundings. The aim of this article is to throw some light on the economic behaviour of the members of the early Church. Did they establish a Christian economy, which was determined by their moral and religious values, or did they adjust themselves to the prevailing economic conditions of the Roman Empire?  相似文献

The common expression of ‘cultural development’ appears in many cultural policy statements without it necessarily arousing questions about its precise meaning. Indeed, we usually spontaneously associate ‘cultural development’ to any governmental intervention that aims at stimulating cultural vitality. However, if we look more closely at the origin of this concept, we soon discover that its appearance on the eve of May 68, in France, corresponds to the rise of new concerns in cultural policy matters and to a radical redefinition of the state’s role in this domain. Still enjoying a strong influence, France’s political transformations were closely followed by some Quebecois politicians and socially engaged intellectuals who were participating, at that time, in the formulation of a new political vision in cultural matters in Québec in the 1960s and 1970s. The objective of this paper is thus to retrace the origin of the idea of cultural development and follow its evolution in Québec.  相似文献

Turkey’s regional policies are inspired by the new regionalism theory. During past two decades, key concepts of new regionalism, including knowledge economies, specialization, networked cities and innovation, have been incorporated in policy documents. At the same time, Turkey comes from a strong central state tradition that controls local and regional development. At first insight, new regionalism and strong central state control do not fit in the same frame. This research analyses the trajectory of regional policies in Turkey with the aim of explaining how these seemingly incompatible policies can coexist. It argues that regional policies developed at the central state level utilized new regionalism as a part of the strategy to maintain power in the course of transformation of the nation state.  相似文献

ABSTRACT

Recent scholarly work has enhanced our understanding of how new path development activities are enabled or constrained by ‘regional environments’, made up of pre-existing industrial structures, knowledge organizations, support structures and institutional configurations. This paper moves beyond overly static views on regional environments. We develop a dynamic perspective by analysing conceptually and empirically how a constraining environment can be transformed into one that enables the development of new growth paths. The paper offers a typology of various modes of change, including layering, adaptation and novel application that are used by key actors to ‘manipulate’ the regional support structures to facilitate new regional industrial path development. The conceptual framework is applied to a case study of the digital games industry in the region of Scania, southern Sweden. Our findings suggest that the creation of a more enabling environment for the growth of the digital games industry has been the outcome of multi-scalar processes and combinations of various modes of change employed by a few key individuals operating in the newly emerging path.  相似文献

Throughout the last three decades efforts to regenerate British cities have been based around the construction of new institutional alliances and policy networks supported by a series of urban-based initiatives. Successive Conservative governments premised their intervention on the assumption that cities (and particular parts therein) were the most appropriate geographical level around which to organise policy intervention. In pursuing this city-based agenda, the policies were themselves instrumental in constituting the city as an object of policy: a problem in need of a solution. The aim of this paper, however, is not to explore how certain spaces or scales become constructed through, for example, government policy, political practices or state restructuring. Rather the paper augments work conducted on the socially constructed nature of ‘cities’ and ‘regions’. It explores for regeneration policy and politics the implications of the tendential shift away from a model of ‘new localism’ towards an alternative model of ‘new regionalism’. The origins of the central element of New Labour's emergent regional project — the Regional Development Agencies (RDAs) — are established before the paper moves on to examine the likely political relationships between the local state, drawing upon the example of Manchester, and the regional state, drawing upon North West England, under the new institutional arrangements.  相似文献

This article provides an overview of the New Partnership for Africa's Development (NEPAD) in the context of Africa's current economic and governance crises, the attempt to establish an Africa Union, and the interest in Africa displayed by the G8 leadership and in particular by the UK's prime minister Tony Blair.
NEPAD has to be seen simultaneously as a 'big idea', a new way of doing business, and a comprehensive development framework. The 'big idea' is to put Africa's concerns on the table of the G8 and seek a much better deal for Africa in terms of international aid, debt relief and access to markets. The new way of doing business is a new form of 'enhanced' development partnership that makes both donor and recipient mutually accountable for development outcomes. The development framework is a long—and expanding—list of programmes and projects, akin to those that have been tried before.
The heart of NEPAD is a commitment to good governance, operationalized through a radical plan for 'peer review' of governance performance. This promises a radical new approach to development partnership, but it also faces political hazards. The governance component is also analysed in the context of the pan–Africa institutions envisaged by the African Union. There is a need for coordinating and rationalizing peace and security initiatives. NEPAD may unlock additional financing for development, but it should not be seen as a cash cow.
The challenges for NEPAD include opening up the process to make it more participatory, including greater focus on HIV/AIDS. NEPAD faces the real danger of being over–sold and of raising unrealistic expectations among Africans. It is, nevertheless, an outstanding opportunity for Africa's development.  相似文献
