Abstract. One of the most challenging developments for students of international relations is the resurgence of ethnic strife, including secessionism and irredentism. Basic questions are only beginning to be addressed in the post‐Cold War era. Why are some states more likely than others to intervene in ethnic conflicts? How can international norms about third‐party intervention in ethnic conflicts be evaded or ignored by some states but respected by others? Why are some states inclined to use force rather than mediation to resolve ethnic strife? In short, what accounts for the emergence of adventurous and belligerent foreign policies with respect to internal ethnic conflicts? These questions are of increasing importance to students of international politics, yet the dynamics and internationalisation of ethnic conflict are far from fully understood. This study focuses on the dynamics of third‐party intervention in ethnic strife and implications for peaceful resolution. The first section presents a model that identifies the general conditions under which ethnic strife is most likely to lead to intervention by third‐party states. The second uses four cases to illustrate, within the context of the model, different processes with respect to internationalisation of ethnic conflict. The third and final stage identifies implications for policy and theory, along with directions for future research. 相似文献

Different glassmaking technologies in the production of Iron Age black glass from Italy and Slovakia
Sonia Conte Rossella Arletti Julian Henderson Patrick Degryse Annelore Blomme 《Archaeological and Anthropological Sciences》2018,10(3):503-521
This study presents the results of an archaeometrical investigation performed on 75 black glass beads dated to the ninth–fifth century BC coming from Bologna, Cumae, and Pozzuoli (Italy), and Chotin (Slovakia). The analyses of the major, minor, and trace elements—as well as that of Sr and Nd isotopes performed on a selection of samples coming from Bologna—provided evidence for two different production technologies in Iron Age black glass found in Italy (natron glass, probably produced in Egypt) and Slovakia (wood ash glass, probably produced in Europe). In both cases, the glasses derive their black colouration from the high presence of iron (around 12 % FeO), introduced into the glass batches through the intentional choice of dark sands. The production model appears to be small-scale and experimental, characterised by the use of non-sorted raw materials and poorly defined formulae, producing glass with a high chemical variability. The wood ash technology appears to have dropped out of use in Europe until the Medieval period, while natron production spread quickly, becoming predominant throughout the Mediterranean. 相似文献

AbstractChina matters significantly to contemporary Australia in terms of trade relations, capital movements, education and global order. Australian public discourse on China, however, inhabits two conflicting parallel universes, one a narrative of economic complementarity, the other of fear and anxiety. The spectre of the rise of China haunts Australian society in and among these two spheres: one in which China’s economic rise is to be encouraged as a sign of it joining the capitalist world system, and the other in which China’s ascent is regarded as a threat to be contained. The paper examines this problematic discourse, calling it Changst [China angst], arguing that it is permeated with a developmentalist logic (Chakrabarty, 2000) that misreads China through the homogenising history of both capitalism and Eurocentrism. This reading of China as but a copy of Western capitalism evokes anxiety because its distinctive forms of capital flow disrupt the comforting teleology. Equally, when Chinese society, including its education system, is perceived as not-yet modern, this induces fear of cultural contamination from the outpouring of Chinese international students. The exploration of this anxiety is conducted via six Australian case studies, showing how China’s engagement with Australia produces intense but unwarranted angst. 相似文献

A batch of green‐ and amber‐coloured glass chunks and unguentaria dating from the first century CE was found in 2007 at Dibba al Hisn, a site on the Arabian Sea coast of the United Arab Emirates (UAE). Its elemental and isotopic composition revealed the glass to be of a previously unknown plant ash glass type, different from known contemporary Roman, Mesopotamian, and Indian glass. The Sr isotopic composition of the glass corresponds to locally available plants, pointing to the possible existence of a first‐century CE local glass production centre. To explore this possibility, sands from around the UAE were analysed to establish their suitability for glass making and correspondence with the Dibba finds. This paper presents the results of the elemental analysis of fourteen sands. The analysis, performed using inductively coupled plasma optical emission spectroscopy (ICP‐OES), revealed all sands to be rich in lime and alumina. X‐ray diffraction revealed the presence of calcite and other carbonate minerals, as well as antigorite and quartz. Comparison of the sand compositions to average first‐century CE non‐Roman glass found at Dibba showed them to be unsuitable as raw material for producing the glass of Dibba. The evidence thus identifies this glass batch as imported, contrary to what was suggested before. This paper also reviews the occurrence of thick‐walled unguentaria in the region. 相似文献
