X-ray fluorescence analysis of obsidian artifacts from sites located in Chaco Canyon and from three Chaco-era communities in New Mexico permits determination of their geological origin. These source data are used to describe patterning in obsidian procurement in sites located in Chaco Canyon dating from A.D. 500–1150, and in a three non-Canyon communities occupied during the period of Chaco Canyon's regional prominence (ca. A.D. 875–1150). These data demonstrate that the most proximate sources generally dominate the sourced obsidian assemblages from sites of all periods, but also suggest differences in procurement patterning both over time and across space. Within Chaco Canyon, there is a notable shift from Mount Taylor obsidian to use of Jemez Mountains sources over time. These data also suggest that earlier analyses of obsidian from sites in Chaco Canyon misidentified some obsidian artifact sources; these new data indicate the central areas of disagreement and provide a revision of procurement patterning. In the Chaco-era communities located outside Chaco Canyon, procurement patterning diverges. The Blue J community shows an increase in use of the nearby Mount Taylor source over time. Two communities located toward the southern extent of the Chaco great house distribution reveal a markedly distinct procurement pattern, obtaining nearly all of their obsidian from southern sources largely unrepresented at Chaco Canyon. Combined, these data provide new insights into raw material procurement and artifact production at sites in Chaco Canyon, and in communities occupied during the Chaco Phenomenon, the period of the Canyon's greatest regional influence.  相似文献

This essay reads Munro’s 2001 story collection as embodiment of her artistic accomplishment. Beginning with a 1952 internal Canadian Broadcasting Corporation reader noting “evocative and luminous phrases” in two of Munro’s earliest stories, it argues that such phrases have informed Munro’s fiction throughout her career. In Hateship, these phrasings are key to “Family Furnishings,” “Hateship, Friendship, Courtship, Loveship, Marriage,” “Post and Beam,” “The Bear Came Over the Mountain,” and especially “Nettles.” There Munro structures her stories around “real facts in the making,” combining autobiographical facts and situations with her imaginative renderings of them. This collection reveals Munro at the height of her accomplished art.  相似文献

社会主义市场经济中的中国税制改革   总被引:2,自引:0,他引:2  
1992年,具有伟大历史意义的中国共产党第十二次全国代表大会确定了中国经济体制改革的目标是建立社会主义市场经济体制。为此,中国于1994年实施了新中国成立以来规模最大、范围最广、内容最深刻的一次税制改革。经过这次税制改革和9年来的逐步完善,中国已经初步建立了适应社会主义市场经济体制需要的税收制度,对于保证财政收入、加强宏观调控、深化改革、扩大开放、促进经济与社会的发展起到了重要的作用。回顾1992年以来中国税制改革、发展的情况,目的在于真实地反映11年来中国税制发展的历程和取得的成就,总结经验,为今后中国税制的进一步改革与发展提供借鉴。  相似文献

Abstract

This paper explores the case of the Khami archaeological site, whose degradation by the local communities in recent years was as a result of socio-economic problems caused by the collapse of the Zimbabwean economy combined with the inability of the Zimbabwean government to support the site. We argue that the negative attitude by the local communities towards the management of cultural heritage sites is embedded in the colonial history of the country, and has been driven by the socio-economic difficulties emanating from the collapse of the Zimbabwean economy in recent years. We begin by explaining the history of Khami, its architecture, and the local communities residing around it. We then show and assert that the subsequent degradation of Khami and the landscape around it by the local communities is linked to the socio-economic problems of the country and poverty, which emanated from the collapse of the Zimbabwean economy. In the end, we contend that the economic constraints are part of the reasons why the local communities have from time to time failed to respect the importance of protecting cultural heritage sites in the country.  相似文献

The 2011 NSW election produced the largest two-party swing in recent Australian election history, ending 16 years of Labor government. It raises the prospect of the end of Labor's dominance of NSW politics. This paper focuses on the consequences of ALP instability for the Party's electoral opportunities and strategy in the lead-up to its 2011 defeat. The authors single out the mass departure of Labor MPs prior to the election and the loss of Greens preferences as interesting problems for empirical analysis. They explore both loss of incumbency and preference effects in a seat-level (n = 93) regression model and comment on the significance of the findings for NSW Labor.  相似文献

This article examines three examples of reconstructive leadership in the 1980s: Reagan in the United States, Thatcher in the United Kingdom, and Hawke in Australia. It finds three primary ways that opposition parties contribute to the success of reconstructive leaders. Firstly, oppositions contribute negatively to the success of presidents and prime ministers through ineptitude and internal division. Secondly, they assist government leaders through engagement with their ideas. Oppositions may agree with the ideas of government leaders, enhancing the leaders' ability to achieve their desired changes. On the other hand, they may disagree and potentially diminish leaders' success. When opposition parties fail to win elections it discredits their alternative ideas, often leading them to adopt government positions. This entrenches the government position, enhancing perceptions of leaders' success. Consequently, when government changes hands, new government leaders consolidate their predecessors' changes – the third way opposition parties aid reconstructive leaders. Thus, oppositions contribute to the implementation of leaders' programmes and to their legacies, two crucial elements in assessing leaders' success.  相似文献
