A new role for the plasmaphere in “quiet” ionospheric electrodynamics

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.     

Italy: A new language for a new politics?

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.     

Sympathy for the Devil?: Australian Unionism and Public Opinion

Public opinion on trade unions is influenced by a variety of factors, including direct experiences of industrial conflict, socialisation, the consonance of union behaviour with values and norms, and the general climate of debate, opinion and propaganda. Union sympathy (general support for unions) slowly declined between the 1940s and the 1960s, deteriorated sharply during the early 1970s, and recovered slowly under the Accord. The deterioration after the 1940s may be attributable to anti-communism's association with anti-unionism. The deterioration during the 1970s was associated with a significant rise in industrial conflict and the slow improvement in sympathy during the 1980s and 1990s was probably linked to the Accord-related fall in it. The decline in union density since the early 1980s cannot be directly attributed to a shift in union sympathy. Despite low levels of disputation in the late 1990s, however, union sympathy then appeared weaker than in the 1940s. Its low level in Australia, compared to other countries, may partly reflect the influence of anti-communism, but especially of arbitration, which rendered strikes illegitimate.     

A new model for royal penance? Helgaud of Fleury's Life of Robert the Pious

This article studies the theme of penance in writings about early medieval kingship through a case study: in his eleventh-century vita of Robert the Pious, Helgaud of Fleury described how the king did penance for his incestuous marriage in terms taken directly from Ambrose's Apologia David . This article, therefore, examines the influence which Ambrose had both on Helgaud and on earlier writers on kingship.     

A continuing confusion? A comment on the appropriate dispersal of policy powers in the Australian federation

Dissatisfaction with Australia's federalist constitutional and administrative arrangements seems universal. The Labor Party has historically preferred a centralist thrust to the Australian federal compact. From the opposite, decentralist tack the Liberal‐National Coalition parties currently propose that the Commonwealth should hive‐off policy functions to the States. These attitudes are expressed in an intellectual climate that disparages the allocative efficiency of Australian federalism and debates these issues in terms of shifting power to or from the Commonwealth. A more sensible focus is on the usage that the citizenry has made of the federal system in obtaining satisfactory service delivery. Using this approach our federal system works efficiently (in a limited political‐administrative sense.

This is not an argument that Australia's federal system is good because it maximises fiscal efficiency or guarantees equity. It does not do the former'and varies in its attainment of the latter. The federal system is good because it maximises opportunities and avenues for citizens to obtain what they want from government. In that sense the Coalition parties are fundamentally confused both about their philosophy and that philosophy's relationship to the political nature of Australian federalism. Labor's slowly‐ebbing centralism equally ignores the political usage that citizens have made of the administrative and funding arenas provided by our federal system.     

Expanding the Australian Empire?: The Australian Council for the World Council of Churches,the Menzies Government and the New Hebrides in the late 1950s

In the late 1950s the Australian Council for the World Council of Churches (AC‐WCC) inspired primarily by the Presbyterian Church, undertook a concerted campaign to pressure the Australian government to assume a greater role in the affairs of the New Hebrides. The AC‐WCC wanted the Australian government to take over the United Kingdom's role in the administration of the Anglo‐French Condominium. It was motivated to undertake this campaign by the dismal social and economic conditions in the islands, the neglect of the British and French colonial authorities, and their failure to offer the indigenous people a way forward to self‐government. The high point of the campaign was a meeting between Robert Menzies, the Australian prime minister and a delegation from the AC‐WCC in early 1958. As a result of this meeting Australian ministers and officials, for the final time, gave extended consideration to expanding Australia's empire in the South Pacific to include the New Hebrides. This article examines the AC‐WCC's campaign, explores the Australian government's response, and analyses the outcome of this important episode in Australia's involvement in the colonial territories of the South Pacific.     

Is Von Thunen Alive and Well? A Transport-Cost Surface for South Australian Wheat

Economic geography has undergone a number of paradigm shifts since the Von Thunen model was at the peak of its popularity in the 1960s and 1970s. This study examines the cost of moving wheat from farm to ship in South Australia and constructs a transport-cost surface for the season 1991/92. Transport costs still exert a very important influence on farm returns and land values. Governments and other authorities, when making decisions in the name of rationalisation, or microeconomic reform, should examine very carefully the spatial consequences of their actions. In the short-run at least, the farmer's world is very much a normative and partial equilibrium one. At least in respect of a significant Australian agricultural enterprise, normative and partial equilibrium models should not be seen as obsolete.     

The Trouble-maker's Ballot Box? A Note on the Evolving Role of the Australian Federal By-election

By-elections have the capacity to result in political outcomes beyond simply filling casual vacancies when they arise. This paper examines data pertaining to federal by-elections in Australia since 1949 in order to ascertain the extent to which there have been changes in these special electoral contests. This paper argues that, although the rate of representational change has not been great in federal by-elections, there has nonetheless been an evolving notion that these contests give non-major party candidates greater scope to influence the political debate. However, it is also argued that this enhanced scope for non-major party 'trouble-making' has been the product of an emerging feature in Australian by-elections-specifically, the increasing incidence of strategic absenteeism by the major political parties.     

Can the Australian Greens Replace the Australian Democrats as a ‘Third Party’ in the Senate?

In this article I discuss the likelihood of the Australian Greens being able to develop into a party that plays an equivalent ‘third party’ role in the Senate similar to that played by the Australian Democrats for most of their existence. My conclusion, based on attitudes underlying voting behaviour, is that they cannot afford to behave contrary to their position as part of a left-wing bloc without jeopardising a substantial part of their voter base.     

Political preferences in the new middle class: A ‘correspondence analysis’ of the orientations of Australian professional workers

Most discussions of the relationship between class and political orientation assume a coherent and homogeneous class response. Here, the new middle class of professional workers is disassembled into constituent occupations. An analysis of political preference data by means of ‘correspondence analysis’ reveals a pattern which is consistent with a structural relationship between occupational experience and political preference.     

The Presidentialisation of Australian Politics? Kevin Rudd's Leadership of the Australian Labor Party

The presidentialisation debate centres on the question of whether contemporary political leaders in parliamentary systems are more powerful than their predecessors. This article applies the presidentialisation thesis of Poguntke and Webb (2005) to the period in which Kevin Rudd led the federal parliamentary Labor Party in Australia. Their model identifies three distinct faces of presidentialisation: the executive face, the party face and the electoral face. This article argues that the evidence of presidentialisation under Rudd's leadership is mixed. The most compelling evidence is reflected in how Rudd interacted with the Labor Party, rather than his interaction with the executive or impact on voting behaviour.

关于总统化的辩论集中于当前国会的政治领袖是否比他们的前任更有权力。本文将普刚克和韦博（2005）的总统化理论应用于陆克文领导澳大利亚联邦议会工党的时期。他们二人总结了总统化的三个方面：行政面、党派面、选举面。本文指出,陆克文领导时期总统化的证据含混不清。最有说服力的证据倒是反映在陆克文与工党而不是与政府的互动或对选举行为的影响上。
