This paper considers the power of abstract formalization in capitalism, via an account of the politics and geography of an equation. The equation in question lies behind the Phillips curve, which describes the relation between price inflation and unemployment or output. I examine the evolution of the equation and its relation to macroeconomics' renewed emphasis, since the late 1960s, on long‐run monetary neutrality. Considering the Phillips curve and its theoretical and technical armature as social practice, I discuss some of the political and distributional questions that arise from the mode of spatial and temporal abstraction particular to modern macroeconomic analysis and policy‐making. The paper has three parts: a brief history of the Phillips curve, an examination of its modern equation‐form, and an analysis of its part in the dialectical process of “real abstraction”, through which logical space and time prioritize and produce both the spatial “macro” and the temporal “long‐run”.  相似文献

As Commonwealth Minister for Employment, Education and Training, John Dawkins has overturned prevailing methods of funding, organization and control of Australian higher education. By making funds dependent upon agreements to pursue national priorities, the Labor minister has also appeared to threaten the dominant objectives and philosophies of higher education. Recent policies (1987–88) have also been regarded as a betrayal of traditional ALP values. This paper argues that such an interpretation misrepresents the history of federal Labor policies in higher education and Dawkins' place within it Tertiary education has usually assumed prominence in the face of either actual or perceived national crises. When in office Labor has usually promoted instru‐mentalism of both an egalitarian and economic kind, and brought about an increasing centralization of Commonwealth control. Federal ALP MPs have also been ambivalent on the values of liberal education and academic freedom. On these grounds, the Dawkins policies represent more of a continuity with, than a departure from, ALP tradition. Any explanation of the Minister's political success must take into account this federal Labor heritage in higher education.  相似文献

Metalliferous (Fe–Cu–Pb–Zn) quartz–carbonate–sulphide veins cut greenschist to epidote–amphibolite facies metamorphic rocks of the Dalradian, SW Scottish Highlands, with NE–SW to NW–SE trends, approximately parallel or perpendicular to regional structures. Early quartz was followed by pyrite, chalcopyrite, sphalerite, galena, barite, late dolomite–ankerite and clays. Both quartz–sulphide and carbonate vein mineralisation is associated with brecciation, indicating rapid release of fluid overpressure and hydraulic fracturing. Two distinct mineralising fluids were identified from fluid inclusion and stable isotope studies. High temperature (>350°C) quartz‐precipitating fluids were moderately saline (4.0–12.7 wt.% NaCl equivalent) with low (approximately 0.05). Quartz δ18O (+11.7 to +16.5‰) and sulphide δ34S (?13.6 to ?1.1‰) indicate isotopic equilibrium with host metasediments (rock buffering) and a local metasedimentary source of sulphur. Later, low‐temperature (TH = 120–200°C) fluids, probably associated with secondary carbonate, barite and clay formation, were also moderately saline (3.8–9.1 wt.% NaCl equivalent), but were strongly enriched in 18O relative to host Dalradian lithologies, as indicated by secondary dolomite–ankerite (δ18O = +17.0 to +29.0‰, δ13C = ?1.0 to ?3.0‰). Compositions of carbonate–forming fluids were externally buffered. The veins record the fluid–rock interaction history of metamorphic host rocks during cooling, uplift and later extension. Early vein quartz precipitated under retrograde greenschist facies conditions from fluids probably derived by syn‐metamorphic dehydration of deeper, higher‐grade rocks during uplift and cooling of the Caledonian metamorphic complex. Veins are similar to those of mesothermal veins in younger Phanerozoic metamorphic belts, but are rare in the Scottish Dalradian. Early quartz veins were reactivated by deep penetration of low‐temperature basin fluids that precipitated carbonate and clays in veins and adjacent Dalradian metasediments throughout the SW Highlands, probably in the Permo‐Carboniferous. This event is consistent with paragenetically ambiguous barite with δ34S characteristic of late Palaeozoic basinal brines.  相似文献

This paper utilizes the Scotch Whisky industry to identify an issue which is absent from the current literature on sector specific clusters namely the concept of power. It is argued that in order to understand the nature of power relationships within a cluster it is necessary to adopt a radical Coasian framework. The paper utilizes a typical Structure-conduct-performance approach to analyse the Scotch Whisky industry and to highlight the problems that power relationships pose within a typical cluster. It is imperative that policy-makers are aware of the power relationships which exist in clusters if clustering strategies are to deliver the perceived potential.  相似文献

The NARA Treaty looked to a strengthened Australia–Japan relationship, which foreign ministers of both countries celebrated this year. Events of the mid 1980s, however, demonstrated how an adverse turn in economic circumstances can stress even a strong bilateral relationship. The two countries were then at opposite points in their economic cycles, Japan almost too successful, with the high yen putting pressure on Japan's export industries, steel in particular. Seeking to reduce costs, the steel mills transferred pressure to their Australian suppliers of coal and iron ore, through reductions in prices and volumes. This was unwelcome to an Australian government coping with a recession and worried about balance of payments and unemployment, and led to concerns about equal treatment. Although the minerals trade returned to normal relatively quickly, ambitious investment projects aimed at enhancing the economic relationship did not materialise.  相似文献

New Zealand has some of the most active areas of rhyolitic volcanism in the world and this has produced numerous obsidian sources in the northern half of the North Island. In total archaeologists have recognized 27 named locations from which obsidian can be obtained scattered across 4 geological source regions. Shortly after colonization in the late 13th century AD Polynesian settlers began transporting this material some thousands of kilometers throughout the country and across the sea in small quantities to distant neighbors in the Kermadecs and Chatham islands. Although considerable research has been conducted on obsidian sourcing in New Zealand the complexity of geochemical source discrimination and the lack of a practical method of non-destructive geochemical analysis has hindered progress. We present the results of our use of PXRF to provide geochemical data on New Zealand obsidian sources and to compare the use of discriminant analysis and classification tree analysis to discriminate among sources and attribute archaeological samples to sources. Our research suggests that classification tree analysis is superior to discriminant analysis in sourcing studies. A large case study using an important settlement phase site (S11/20) from the Auckland region demonstrates the utility of the methods and the results support a model of high degrees of mobility and interaction during the early settlement of New Zealand.  相似文献
