博物馆,档案馆,图书馆被保护环境中气态污染物的监测和分级 总被引:1,自引:1,他引:0
过去几十年,美国普滤公司合作开发了一种可以用来精确评价被保护环境中存在破坏可能性的技术,用来保护珍贵的文物,艺术品及历史档案资料。他们一方面研究开发了能精确评估被保护环境的反应监测仪器和监测技术,另一方面又制订一套新的环境分级标准,使文物保护者了解被保护环境是否是安全的。现把这种文物、档案、图书保存环境的反应监测技术和环境评估的新标准介绍给国内的同行们。 相似文献

商末黄河中游气候环境的变化与社会变迁 总被引:21,自引:0,他引:21
新石器时代到商代黄河流域的气候属于温暖湿润期;商代后期气候出现厂干旱化,导致了古公亶父迁岐,文王迁程迁丰,帝乙帝辛时不断向南方发展;而商末的旱灾和饥荒是周武王克商的直接导火索,导致商周之际的改朝换代。商末气候环境的变迁对其时社会政治的影响极大。 相似文献

近几十年流行唐代进:仁难、明经易说,所持理由一是两科录取率相差悬殊,二是两科考试内容不同,难易有差。考察具体情况,不是这么回事。实际情况是,进士、明经,难易相当。 相似文献

二十世纪有关纸的考古发现不能否定蔡伦发明造纸术(1) 总被引:1,自引:0,他引:1
近几十年来,我国考古工作曾先后在一些西汉遗址和墓葬中发现了若干纸状残片,于是引起国内外许多学和广大人民的关注和提出疑问。是否蔡伦前约二百年就有了纸?造纸术还是不是蔡伦发明的?新发掘的纸状物到底是个什么样?经对历次的发掘作了详细的调查研究和分析化验,结论认为:20世纪有关纸的考古发现不能否定蔡伦发明造纸术。 相似文献

民国时期,桂系集团所实施的治桂方略中,“控制”和“发展”的成分共存。由于其立足点为开发经济、促进民族融合,因此为后来社会矛盾的缓解和边疆地区的稳定奠定了较好的基础。政府力量之所以能够发挥积极的作用,既取决于其职能的转变,也取决于相关社会因素的推动。 相似文献

Indigenous methodologies in geography have recently been developed to decolonise Western dominated paradigms. It has been argued that research which does not benefit Indigenous communities should not be conducted. However, Indigenous methodologies are not taught in many post-secondary institutions. Therefore, when they pursue Indigenous topics, many junior researchers are self-taught in these methodologies. However, these methodologies cannot be defined simply and they are too diverse to be learnt in a short period. In Japan, Indigenous peoples are not widely recognised and research on contemporary Indigenous issues is limited. The concept of Indigenous methodologies is rarely discussed. Because of this, Japanese researchers rarely identify their research as adopting an Indigenous methodology. Indigenous researchers are thereby discouraged from pursuing Indigenous methodologies. Furthermore, a methodology or a thesis statement used by researchers to reflect Indigenous perspectives often gets little support from Indigenous peoples. My master's research on the Ainu mirrored this situation. While Indigenous methodologies remain difficult to learn, junior researchers should not be discouraged from this form of engagement. Practical suggestions are therefore necessary to encourage their use and application. Based on my experience, I suggest that researchers approach Indigenous communities from a learning perspective. This would encourage open-mindedness and sensitivity. Researchers should also be prepared and willing to refine their research questions and to continue their literature searches after their fieldwork is completed. These strategies could limit misinterpretation and exploitation of Indigenous knowledges and peoples. 相似文献

AbstractThe Maldives resort islands are a type of tourist enclave subject to a dual form of borderization. The islands have an external border that coincides with each island’s coastline and with the limits of the private property of the resort; this border regulates the movement of tourists and locals. The islands also have an internal border that separates the outer edge of the island from the inner edge. The outer edge, which is supposed to represent the perfect landscape of the ‘tropical island,’ houses all of the tourist facilities, while the interior contains the structures dedicated to the metabolic activities of the resort. The frontline staff members and the tourists share the ‘dreamscape’ of the outer edge, whereas the maintenance workers live in the secluded space inside the island, where they are typically hidden from the sight of tourists by high walls, and their movement is usually restricted from staff designated areas to their location of work. For maintenance workers, these spaces, necessarily limited due to the small size of the coral islands, risk becoming ‘islands within islands.’ Recently, the Maldivian government has begun to promote projects and initiatives in support of territorial integration between the resorts and communities of neighboring islands. Thus, the outer limits of the resort islands are, today, more porous. Their internal borders, in contrast, remain very difficult to cross. 相似文献
