One of the central issues in substorm research is what determines the substorm intensity. Through an introduction on what constitutes a magnetospheric substorm, we discuss several parameters which are available to measure the substorm intensity. In terms of ionospheric quantities, we have the auroral electroject indices, the total current in the westward auroral electrojet, the area of bright aurora, the maximum poleward advance of the auroral bulge, and the duration of auroral substorm activities. In terms of magnetospheric quantities, we have the innermost location of the substorm injection boundary and the amount of current reduction in the cross-tail current within the substorm current wedge. A measure reflecting substorm activities in both the ionosphere and the magnetosphere is the total substorm energy dissipation but its drawback lies in the difficulty of assessing it accurately if the energy loss due to plasmoids is to be included. We also discuss the predictability of substorm intensity, which leads us to the issue of whether a substorm is a directly-driven or an unloading process. The recent success in predicting the auroral electrojet index from solar wind parameters with a cross-correlation of ~ 0.9 suggests that substorm activities over a long time scale are primarily directly-driven while those over a short time scale are governed by impulsive unloading processes. This understanding allows us to reconcile the apparently conflicting dual nature of magnetospheric substorms.  相似文献

The purpose of the Swedish State Institute for Race Biology, SIRB, was to survey the Swedish people according to its race criteria. In this research process photographs were used to document and portray the different races living in Sweden. This article examines how the photographs were used in this process: What pictorial rhetoric did they use and what did the photographs bring to the research process? The result shows that SIRB did not succeeded in developing consistent methods of portraying race. The style and formula of the portraits varied; sometimes environmental aspects came in to focus, sometimes bodily aspects. These methodological shortcomings must be attributed not only to the fact that the institution was working with a new and immature scientific medium – photography – but also that it operated inside an immature scientific discipline. The race scientific community had no joint theories and methods to work with, and did not know how to affiliate with other disciplines – such as anthropology, focusing on environmental factors, or medicine, focusing on bodily aspects. But the lack of methodological consistency was not just a shortcoming; it could also be used to bias the material in a way that served the ideas of eugenics.  相似文献

The period between the holding of the National Economic Summit Conference in April 1983 and the 1984 election has seen the politics of the Accord shift from a primary concern with wage setting through the Arbitration Commission to the management of trade‐offs in non‐wage areas between business, government and the ACTU. The politics of the Accord in this period is not understood by adopting an interest group approach to business, the ACTU and the government or by accepting EPAC's view of its own institutional role. Rather, business and the ACTU obey two different logics of collective action and Epac is a ‘disorganising’ institution. It is a representation system based on closure by exclusion called partial corporatism. Partial corporatism benefits business disproportionately and excludes women, welfare recipients and the unemployed.  相似文献

Cultural and economic heterogeneity is often seen as a major threat to modern welfare states. This article contributes to the discussion of how much heterogeneity the welfare state can endure by theoretically and empirically focusing on the relationship between different levels of national identity and the support for welfare state policies. We analyse the effect of different types of national identity on attitudes towards taxation and redistribution. We show that it is the subjective aspect of national identity, or social cohesion, that in fact matters for predicting attitudes to the welfare state. In comparison, more objective measures of heterogeneity like the inequality of income distribution, language fractionalisation or the percentage of foreign‐born individuals do not have any effect on attitudes to the welfare state.  相似文献

This paper analyzes the influence of transportation infrastructure, and in particular of the Regional Express Rail (RER), on employment and population growth in the Paris metropolitan area between 1968 and 2010. In order to make proper causal inference, we rely on historical instruments and control for all other transportation modes that could be complement or substitute to the RER. Our results show that proximity to an RER station increases employment and population density and, in particular, employment and population growth. The latter effects are higher in municipalities located near RER stations and close to employment (sub)centers. They are also found to be particularly strong for jobs in the service sector, for factory workers, and for highly educated population. We find no impact of the RER expansion on employment growth during the first part of the period, while the effect on population growth appears earlier but declines over time.  相似文献

This paper analyses the effect of location characteristics on urban growth using regression cubic splines. Our empirical analysis shows that in Spain, differences in accessibility to major urban centres and geographic isolation help explain differences in population growth rates across municipalities between 2001 and 2014. Moreover, even though physical proximity to large cities is usually assumed to be closely related to the attractiveness of a municipality, we found that urban population growth is even more related to the joint effect of distance to major centres and agglomeration. In this respect, there seems to be a threshold from which agglomeration diseconomies come into play such that a greater proximity to major cities and/or being localized within a more densely populated area goes against local growth.  相似文献

As economic activity becomes increasingly globalized, partly by means of new information and communication technologies (ICTs), one of the key expectations of European policy-makers was that businesses in rural regions, and particularly in peripheral rural regions, would overcome some of the disadvantages of their locational contexts, and become more effective participants in larger market areas. This paper examines the reality of ICT exploitation by rural business across Europe, based on a survey of 600 enterprises in 12 regions located in Ireland, Scotland, Germany, Spain, Greece and Finland. Not surprisingly, a range of outcomes has been identified in terms of telecommunications infrastructure and ICT usage, which reflect considerable differences in access to reasonably priced broadband telecommunications, awareness of how the technologies can be exploited, and in levels of skills to translate that exploitation into a means of competitiveness.  相似文献

ABSTRACT

Nuclear exports were a crucial part of West Germany's nuclear industry. Its domestic market was too small to keep a big nuclear industry alive. But nuclear exports were subject to a nonproliferation regime which West Germany had accepted when signing the Nonproliferation Treaty (NPT). During the 1970s, there were major quarrels with the United States about West Germany's nuclear export policy and its approach to the nonproliferation regime. Using sources from several German archives, this article examines the nuclear export policy of West Germany and the patterns of justification as a further development of the nonproliferation regime. It is focused on two different cases, the nuclear export to Brazil and to Iran, which are strongly connected and both included sensitive technology such as reprocessing and enrichment.

The export cases touch on the issue of further development of the nonproliferation regime, the emerging nuclear world order and broader conflicts about the hegemonic and discriminatory structure of the NPT. The way West Germany handled US criticism of the exports shows West German willingness to shape its own foreign policy and the attempt to gain independence from US dominance, thus contributing to the decline of bipolarism and strengthening middle powers.  相似文献

Abstract

This article addresses the role of the ‘civilizing process’ in the historiography of the Victorian period. The author develops a critique of perspectives that deem the nineteenth century to be an era of discipline and self-restraint, arguing that these result from the hegemonic position of literary perspectives within Victorian Studies and their frequent reliance on Foucauldian-inspired techniques of discourse analysis. In response, he outlines and illustrates the potential for alternative research agendas and approaches that move away from representational sources in order that the Victorian period can be viewed in a new light. These include the study of vernacular photography, cultures of leisure, and the subcultures of groups where the importance of ‘nonverbal’ practices and the cultures inherent in bodily experiences are highlighted – forms of expression that reach beyond established discourse. It is argued that the failure of scholars of the Victorian period to consider this ‘nonverbal’ culture means that the theoretical frameworks of comprehension that currently characterize Victorian Studies are underdeveloped. The essay calls for Victorianists to broaden their theoretical perspectives, engage with new sources, and embrace new methodologies in order to enlarge our understanding of nineteenth-century culture.  相似文献

The law and constitution of the family has been targeted for transformation in recent years, leading most notably to the Supreme Court's decision in Obergefell v. Hodges, mandating same-sex marriage as a matter of constitutional law. In this essay I undertake a thought experiment, asking how advocates of traditional marriage ought to want the law of marriage to change in light of this development. I begin by reviewing the argument for legal change sketched by Aquinas and then applying it to developments concerning marriage in modern America. Next I sketch the natural-law argument on behalf of traditional marriage. Finally, I turn to the case of Michael H. v. Gerald D., in which the Supreme Court upheld a statutory reiteration of the common-law presumption that the husband of the mother is the father of her child, against a challenge from the biological father, suggesting that this case, long admired by conservatives, needs to be reconsidered—and that the dissent in the recent Indian Adoption Case recognizing a constitutional right of biological parents might prove useful to the restoration of marriage law.  相似文献

ABSTRACT. This article argues that understanding national identity requires a reappraisal of friendship as a political sentiment. Although studies of nationalism underscored the transformation of face‐to‐face interactions into ties between ‘distant others,’ they failed to acknowledge how sentiments of friendship may be involved. First, following theorising in political philosophy, the Aristotelian paradigm of civic friendship is conceptually applicable to modern civil society based on characteristics such as volition, commitment and sentiment. Second, feminist scholarship has delineated how an implicit discourse of male fraternity underlies the historical realisations of the modern social contract and mediates the notions of both patriotism and nationalism. Finally, networks of male associations and transformations in collective affection from small settings to large‐scale societies contributed to the magnification of a politics of friendship. Consequently, rather than viewing fraternal friendship as a relic of traditional societies, it should be studied as a unique aspect of modern nationalism.  相似文献

The Arrow Lakes Band was the only form of legal recognition ever made available to the Sinixt nation by Canada before they were declared extinct. The Oatscott reserve and the state were cartographies that both summoned and willed away the Sinixt. I attempt a “politics of witnessing” of recent Sinixt activities as they push back against these colonial enframings and displacements. I then contextualize biopower within settler society to chart the production of the state through a cultural economy of racialization and erasure, and through a clearing of the land based on more explicit imaginative geographies. The declaration of the extinction of the Sinixt illustrates Indian reserves less as a disciplinary and more a sovereign technology. And yet it is quintessentially modern owing to the absence of instrumental violence. Finally, the limitations of witnessing and the space Indigenous peoples make for alliances are examined.  相似文献

How much did the 19th-century rural schoolhouse cost to build? On the basis of a study of schoolhouse building in the Sundsvall region in the period 1842–1900, this article shows how the cost of school buildings increased over time, both overall and by schoolhouse, largely because of the marginalization of cheaper and simpler redevelopment projects, as well as the construction of a number of more expensive schoolhouses. Through the use of extensive source material, preserved from the building of 66 schoolhouses, a more detailed analysis of these developments has demonstrated differences in price levels between purchased schoolhouses, redevelopments of existing buildings and new building projects, and buildings intended for different types of schools. Insights are also given into labour and material costs. In addition to establishing basic facts about a main feature of the expanding system of mass education, this study thus makes a reinterpretation of the 19th-century rural schoolhouse which emphasizes new patterns of development and fundamental distinctions, presenting schoolhouses as a social and economic issue, rather than an architectural or pedagogical concern. Instead of being described as rather simple buildings, in comparison with the major buildings in the cities, schoolhouses thus appear as a major item of expenditure for local government.  相似文献

As universities around the world are under pressure to produce commercial outputs of their research results, it is surprising how a few studies have been conducted about intermediary organizations and their role in this matter. The intermediaries’ basic roles to diminish market and system failures in innovation processes are targeted to respond to the challenges that may emerge in innovation processes, in general, especially in the commercialization of academic research. In this article, we analyse the roles of, and needs for, different kinds of intermediary organizations in two Finnish technology agglomerations from the perspective of the commercialization of new knowledge. We use the Triple Helix concept as a theoretical starting point for our empirical analysis. As many challenges in Triple Helix linkages prove that policy interventions to support the activities of intermediary organizations are justified up to certain point. However, the role of these “go-between” actors may also be irrelevant if networks between university–firm–government helices function well. In addition, many of the challenges in the commercialization of new knowledge originated from the failures of policy implementation concerning the public or semi-public intermediaries.  相似文献

This article argues that the Avestan text Yasna Hapta?hāiti (“Yasna of the seven chapters”) was not originally divided into seven chapters. It was divided into three parts that were not considered hāitis (chapters) in the same way as the gathic hāitis. The division of the Yasna Hapta?hāiti into seven parts and its corresponding title is based on the arrangement of the Old Avestan texts. These texts try to reproduce the structure of the prayer Ahuna Vairiia; three verses with two hemistichs each correspond to three pairs of compositions with 7, 4 four and 1 hāiti each of the Old Avestan texts.  相似文献

The Coalition's clear victory over Labor at the 2004 federal election after prominent campaigning by conservative church-based groups – along with the election to the Senate of a member of the Family First party – seemed to many commentators to confirm the growing power of a ‘Religious Right’ in Australia. This paper argues that two features of the 2007 federal election campaign are impossible to square with the rise of the Religious Right thesis. First, Labor won in 2007 without shifting its leadership, policies or electoral strategy to suit the Christian Right. Second, the contributions of church groups to the 2007 election campaign were not dominated by a single perspective but covered a wide range of issues and expressed competing views on key policy issues. This pluralism allowed Kevin Rudd, the Labor Party and even the Greens room to present themselves favourably to significant groups of Christian voters. The 2007 election suggests that, rather than being dominated by a hegemonic Christian Right, church involvement in Australian electoral politics is pluralistic in character.  相似文献

Both the European Union and NATO are now committed in principle to substantial enlargement. It remains doubtful, however, how far member governments are making a success of further enlargement, let alone thinking through its strategic implications. Yet the process of dual enlargement will define the future security, political and economic structures of the European region. During the past year west European governments have extended promises of eventual membership to the western Balkan states and to Turkey; while the future positions of Ukraine, Russia, the Caucasus states and the southern Mediterranean associates all raise delicate policy issues. Hard choices remain to be made about the adaptation of these organizations to eastern enlargement, and about the management of relations with the near neighbours who will remain outside.  相似文献

This article examines the extent to which terrorist use of nuclear, chemical, and biological weapons poses a tangible threat to international security. In the literature on terrorism and weapons of mass destruction (WMD) some analysts have tended to exaggerate the scope of the threat and assumed that large-scale terrorist acts involving WMD are only 'a matter of time'. In short, there is a tendency among observers to converge on analogous assessments at the higher end of the threat spectrum. In this article I argue that although WMD terrorism remains a real prospect, the ease with which such attacks can be carried out has been exaggerated; acquiring WMD capabilities for delivery against targets is a lot more problematic for terrorists than is generally acknowledged in the literature. However, this is not to say that the possibility of such attacks can (or should) be ruled out. The rise of a 'new' brand of terrorism that operates across transnational networks and whose operations aim to inflict mass casualties, coupled with the destructive threshold crossed on 11 September 2001, mean that terrorist attacks using WMD will continue to be a realistic prospect in the future.  相似文献
