Over half of all young people in Australian government schools do not complete secondary education and leave school without any formal qualification. This paper uses a regional framework to examine long-term trends in retention rates in different areas of Melbourne and concludes that in both older established and newly urbanized parts of the city the post-war transformation of government high schools into a mass system has failed to break down barriers based on social area. Marked regional differences were found in demand for high school, as well as a long downward trend during the 1970s (despite recession). Technical schools have displayed comparatively minor regional differences and retention rates grew during the 1970s. This suggests that the academic curriculum of high schools continues to be culturally selective. In addition to residential differentiation, important structural features, such as the relative over-supply of technical school places, were identified as contributing to regional trends.  相似文献

Excavation and surface survey at the site of ancient Merv, Turkmenistan has led to the recovery of a large number of coins, including a small number of Late Roman and Byzantine pieces. These coins are listed, and placed in the wider context of Roman coin finds far beyond the boundaries of the Roman Empire. The implications for east-west relations at this period are discussed.  相似文献

Summary. Recent discussions of continuity between Roman and Saxon Britain have not considered in detail the bases of dating, or the model which is being used to explain the transition from one state to the other. This builds considerable dangers and uncertainties into any future work. The problems inherent in late Roman and Early Saxon chronology are aired, the two most obvious current models of transition are considered, rejected, and replaced by a model involving minimal population movement but total change in fashions.  相似文献

This paper describes the discovery of the first open‐air Upper Palaeolithic site to be found in Scotland, at Howburn, near Biggar in South Lanarkshire. An account is given of the composition and distribution of the lithic assemblage, which is discussed in terms of its British and north‐west European context. Provisional parallels drawn are with the Late Hamburgian (Havelte) sites and assemblages of southern Scandinavia, northern Germany and the Netherlands. There is no absolute dating evidence for the site, but an age in the region of 12,000 14C yr BP, towards the end of the earlier (Bølling) Lateglacial Interstadial stage, is proposed on the basis of the lithic artefacts.  相似文献

The unravelling of the post‐Cold War security order in Europe was both cause and consequence of the crisis in Ukraine. The crisis was a symptom of the three‐fold failure to achieve the aspirations to create a ‘Europe whole and free’ enunciated by the Charter of Paris in 1990, the drift in the European Union's behaviour from normative to geopolitical concerns, and the failure to institutionalize some form of pan‐continental unity. The structural failure to create a framework for normative and geopolitical pluralism on the continent meant that Russia was excluded from the new European order. No mode of reconciliation was found between the Brussels‐centred wider Europe and various ideas for greater European continental unification. Russia's relations with the EU became increasingly tense in the context of the Eastern Partnership and the Association Agreement with Ukraine. The EU and the Atlantic alliance moved towards a more hermetic and universal form of Atlanticism. Although there remain profound differences between the EU and its trans‐Atlantic partner and tensions between member states, the new Atlanticism threatens to subvert the EU's own normative principles. At the same time, Russia moved from a relatively complaisant approach to Atlanticism towards a more critical neo‐revisionism, although it does not challenge the legal or normative intellectual foundations of international order. This raises the question of whether we can speak of the ‘death of Europe’ as a project intended to transcend the logic of conflict on the continent.  相似文献

Metropolization and the rank/size ’law‘: the Canadian case, 1971–2001 There is currently considerable interest in the process of metropolization. One of the consequences of this process, observed by numerous researchers, is the slower growth and even decline of small and medium cities. From a theoretical point of view, this process is compatible with endogenous growth theory: metropolitan areas offer economic actors certain key factors (access to information, to global networks, etc.) that smaller cities cannot. Concurrently, however, there is a resurgence of interest in Zipf's law and, more generally, in the stability of urban hierarchies. These two bodies of work appear to be in contradiction. However, using Canadian data from 1971 to 2001, we show that whilst metropolization is indeed occurring, this is not necessarily incompatible with a regular urban hierarchy. Indeed, if it is assumed that Zipf's rank‐size rule applies to urban systems in stable socio‐economic contexts, and that this regularity can be disrupted by fundamental social and economic changes, then the current wave of metropolization can be interpreted as a re‐ordering of cities in the face of the major social and economic changes of the 1980s and 1990s, which may eventually lead to a new equilibrium compatible with Zipf's law.  相似文献

Geomorphology in Canada, as elsewhere, has evolved into an essentially bipartite discipline focusing either on ‘process’ or broader ‘historical’ (Quaternary) landscape interpretation. A growing emphasis on process‐oriented research that relies increasingly on instrumentation and computational technologies has occurred. Critics of such research note limited applicability for landscape evolution, fashionability of methods and limited societal relevance. Indeed, some say we are not seeing the landscape for the processes. This article discusses the changing nature of geomorphology since the Quantitative Revolution of the 1950s including new advances, recent trends and challenges. Publication trends and recent advances suggest that the discipline is very healthy (following a slump in the early 1990s) and continues to evolve, which may reflect increasing research infrastructure and/or funding opportunities and new publications spotlighting Canadian research. Unfortunately, fundamental (less applied) research is threatened by funding program shifts, changing institutional pressures and a decline in research capacity from retirement attrition, and student recruitment challenges. Three research priorities are recommended: (1) continued fundamental research, (2) more integrated modelling to link micro scale processes to macro scale landform behaviour and (3) improvements in profiling our discipline amongst students and related professionals.  相似文献

The example of the UK is used to explore two linked ideas relevant to the current international politics of nuclear weapons: that of the threshold state, whereby a state moves from possession to non‐possession of weapons rather than in the opposite direction; and that of responsible nuclear sovereignty, adapting the notion of responsible sovereignty to the nuclear context. The UK regards itself as an exemplar of responsible nuclear sovereignty and is closest to the disarmament threshold, being driven closer by military and economic stresses. Nuclear disarmament will require all nuclear‐armed states to approach and cross this threshold, a journey assisted albeit ambiguously by the shared practice and norms of responsible nuclear sovereignty. Yet the nine nuclear‐armed states' relations to the threshold differ markedly, raising more questions about the feasibility of the popular model of coordinated disarmament. Although coordination remains desirable, the UK seems more likely to abandon its nuclear force by deciding that ‘enough is enough’ than through the conclusion of a grand multilateral initiative.  相似文献
