In 1856, the Treaty of Paris nominally welcomed the Ottoman Empire into the Concert of Europe, but this exposed a deep fault line in international relations. Although the gesture implied full sovereign rights, it seemed incompatible with the extraterritorial privileges held by Europeans in Ottoman lands under the age-old capitulations. New commercial treaties complicated the issue by extending similar privileges to British subjects as far afield as China, Siam and Japan. Consular jurisdiction soon became the focus of controversy in Westminster as extraterritoriality featured prominently in local disputes following British commercial expansion across Asia, among them the Arrow incident that led to the Second Opium War. In Japan and other states, it would also become a key grievance in popular campaigns against ‘unequal treaties’ and the injustices of informal empire. This analysis shows how, even before such narratives of resistance emerged, there was already a seam of ambivalence in Victorian political discourse on the question of extraterritoriality. In the Foreign Office, it came as no surprise to be told of defects in these treaties, but it was the context of the existing debate, notably fresh initiatives to set up mixed courts, that framed the British response.  相似文献

Zooarchaeologists frequently measure taxonomic evenness to document subsistence change and to understand the response of faunal communities to paleoenvironmental change. Although the measurement of evenness is commonplace, there are numerous challenges involved. Evenness indices are sensitive to changing richness, and by extension sample size, and various indices respond differently to changing taxonomic abundances (i.e., changing evenness). To refine protocol for comparing assemblages of varied sampling effort and identify indices that may be more useful for zooarchaeological applications, we examine the quantitative behavior of the widely used Shannon evenness and Simpson indices and two others more commonly used by ecologists. These indices are examined in relation to varied richness, sample size, and taxonomic abundances. We show that although zooarchaeologists are concerned with identifying and correcting for the effects of sample size on evenness, it may be appropriate to instead focus on how richness modulates evenness. Based on our analyses, we recommend the Simpson index for most zooarchaeological applications, except when comparing evenness across assemblages that are very even.  相似文献

Intensive farming is an increasing part of Australian agriculture, including in the multi‐functional landscapes at the edges of Australian cities. The example of intensive “broiler” poultry production reveals the tensions that arise when sites of hyper‐productivity conflict with social change in rural areas. Planning processes for intensive farming in the Australian state of Victoria are predicated on stability and consensus: on assumed static and uncontroversial ideas of agriculture, its place, and the primacy of agricultural productivity. Yet concerns about the industrialisation of agriculture are live political issues at the local level, especially in dynamic peri‐urban locations. This paper explores the emergence of a politics of place outside the bounds of planning consensus through an analysis of planning appeals and associated media relating to planning permits for intensive poultry developments in Victoria over 2011–2016. We highlight tensions that exist in relation to technical planning assessments and categorisations used to assert farming as the orthodox use of rural land, especially when new forms of farming look and feel demonstrably different. Using Mouffe's problematising of the negation of antagonism and Rancière's notion of the risks of a false consensus democracy, we argue that planning processes for intensive farming illustrate critical issues in participatory planning. While ostensibly post‐political decision‐making narrows the politics of place and food systems to decisions about policing the boundaries and buffer distances placed around intensive poultry developments, alternative representations of rural life persist. The certainty offered by code‐based planning does not negate the ongoing (if inconvenient) politics of intensive peri‐urban agriculture.  相似文献
