The discourses of classical scholars during the eighteenth century reinforced a shift from Song-Ming rationalism to a more skeptical and secular classical empiricism. By making precise scholarship the source of acceptable knowledge, Qing classicists contended that the legitimate reach of ancient ideals should be reevaluated through comparative delineation of the textual sources from which all such knowledge derived. This turn to empirically based classical inquiry meant that abstract ideas and rational argumentation gave way as the primary objects of elite discussion to concrete facts, verifiable institutions, ancient natural studies, and historical events. In general, Qing classicists regarded Song and Ming “Learning of the Way” as an obstacle to verifiable truth because it discouraged further inquiry along empirical lines. The empirical approach to knowledge they advocated placed proof and verification at the heart of analysis of the classical tradition. During this time, scholars and critics also applied historical analysis to the official Classics. Classical commentary yielded to textual criticism and a “search for evidence” to refortify the ancient canon. Representing a late imperial movement in Confucian letters, Qing classicists still sought to restore the classical vision. The early modern power of their philology, however, yielded the forces of decanonization and delegitimation as modernist trends, which went beyond the intellectual limits they had imposed on their own writings.  相似文献

The earliest metal objects and metal production practices appeared in Western Europe during the fourth and third millennia BC. The presence of earlier dates for copper, gold, silver, and lead, as well as arsenical copper and tin-bronze alloys in Central and Eastern Europe implies that there is no evidence for the independent invention of metallurgy in Western Europe. Instead, the acquisition of metal objects as exotica by communities appears to have led eventually to the movement of people possessing metallurgical expertise. However, the metals, production techniques and object forms used in each region reflect local standards seen in other materials. This implies a process of incorporation and innovation by the communities involved rather than a straightforward or inevitable adoption. The presence of metal may have created new networks of communication and exchange but, due to its small scale, there is no evidence for any metallurgical revolution.  相似文献

This paper compares the performances of three exploratory methods for cluster detection in spatial point patterns where the at-risk population is known. After reviewing two existing methods, Openshaw et al. (1987) and Besag and Newell (1991), an alternative method is introduced. These three methods are then compared empirically using two point patterns drawn from a disaggregate housing database consisting of 28,832 observations. Each observation in the data set contains attributes of single-family detached dwellings in the City of Amherst, New York. This paper provides some new insights into the performance of the three methods, as previous applications have used spatially aggregated (and hence rather inaccurate) data. The paper also demonstrates the utility of GIS for this type of spatial analysis.  相似文献

… with a rule and a pair of scales, and the multiplication table always in his pocket, Sir, ready to weigh and measure any parcel of human nature, and tell you exactly what it comes to. It is a mere question of figures, a case of simple arithmetic. Mr Gradgrind in Dickens's Hard Times. Research has indicated that in rural areas, the income of the poor has increased faster than that of the rich … in 1967, 9 out of 10 Indonesians lived below the poverty line; in 1970, 8 out of 10, and in 1976 only 3 out of 10. This means the benefits of development are being distributed … How do we react to these figures? One may still suggest various reservations concerning the indicators of increasing equality. For example, it should be made clear to the layman to what extent the poverty line standard based on the World Bank research is sufficiently valid and objective to be used as a measure and a guide for Indonesian society. We also need further clarification of the more rapid income increases among the poor compared to the rich in rural society. For according to other research, they say that the gap between land-owners and labourers is also increasing. Kompas editorial, 18 August, 1977, Jakarta (translated).  相似文献

Ambitions for a European “circular economy” imply waste is becoming an important “commodity frontier”. Increased recycling in Europe has been accompanied by a proliferation of informal waste work. “Southern” geographies of informal recyclers provide resources for interpreting this phenomenon but studies of a commodity frontier in urban waste have tended to focus on moments when informal waste workers are displaced by capital intensive waste management systems. I draw on concepts in world-ecology and materialist ecofeminism to explore the proliferation of informal waste workers in Barcelona and the way their (re)production produces “Metabolic Value”. Informal waste work is shown to emerge and persist as part of a commodity frontier process—where the appropriation of unpaid work from non-commodified spaces is the hallmark of how capitalism secures “Cheap Nature”. The study suggests that, rather than internalising ecological costs, recycling often rests on the appropriation of value from uncommodified spaces.  相似文献

This article deconstructs United Nations Security Council (UNSC) Resolution 2094 through the preambulatory statements, objectives, obligations, and implementation and enforcement provisions of UNSC Resolution 2094. The article proceeds in three parts. First, it reviews the academic literature on UNSC sanctions and their application in the North Korean case. Second, it deconstructs UNSC Resolution 2094 according to the common structural components of international legal instruments to assess the level of congruence between the objectives of UNSC Resolution 2094, its enforcement mechanisms and outcomes. Third, it explores the weaknesses of UNSC Resolution 2094, focusing on the gap between the objectives and enforcement mechanisms found in the resolution. The inability of the UNSC sanctions regime to prevent North Korea reaching the cusp of becoming a nuclear weapons power is evidence of the international community's weak leverage over Pyongyang, a situation arising from the vulnerability of South Korea to a North Korean attack and the cross-cutting strategic priorities of China; the absence of economic linkages between the Democratic People's Republic of Korea and the primary sanctions-sender state in the USA; and North Korea's commitment to a nuclear weapons capability as the foundation of its medium-term economic development strategy, its institutional governance structure and associated ideological commitments.  相似文献

This piece is an imagined email correspondence between three renowned international relations scholars, E. H. Carr, Hedley Bull and Coral Bell, who are discussing the Australian 2016 Defence White Paper. The purpose of such an exercise is to reflect on the ‘big-picture’ international relations questions posed by what might otherwise be thought of as a relatively technical defence policy document. In particular, the correspondence between the three focuses on the central importance of the White Paper’s assumptions of a ‘rules-based global order’ and the relationship between this order and US power. In their time, all three authors spoke directly to questions of power, law and order in their scholarly work, which had been deeply influenced, in all three cases, by periods spent working at the ‘coalface’ of these issues in government in Britain and Australia. As such, Carr, Bull and Bell have much to say about how Australia is positioning itself for a post-unipolar world.  相似文献
