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

略论晚清汉学的兴衰与变化 总被引:4,自引:0,他引:4
晚清时期,兴盛于乾嘉年间的清代儒学主流学派-汉学-尽管走上衰落的道路,但这种衰落并非直线性地下降,而是经历了一个较长的曲折变化的过程。自鸦片战争到中日甲午战争长达半个多世纪的时间里,汉学依然是中国学坛人多势众、著述丰富、分布广泛的强势学派,居于学界“老大”的地位。晚清汉学家们秉承乾嘉宿儒治学传统,在经学、小学、音韵学等领域开展深入研究,取得显著成就,甚至在某些方面直驾乾嘉而上。晚清汉学因处于与乾嘉汉学完全不同的社会环境,形成“实”、“通”、“变”的历史特征,并随着中国传统社会发生根本性的变化而实现着自身的新旧更替。晚清汉学既沿袭了传统儒学的许多消极因素,也包含着其中的积极成分,对中国近代社会文化产生了复杂而多重的影响。 相似文献

In traditional Bantu-speaking societies in southern Africa, drought is caused by breaches in rules of pollution. At times of severe drought (3–5 consecutive seasons), rainmakers ascend special hills to perform special rituals. The archaeological signature of this unique activity forms a cultural proxy for drought. New research shows that burnt daga structures also correlate with high δ15N values for small stock. Burnt structures thus form a new component to the proxy. According to the ethnography, farmers implicated in the cause burnt their grain bins, and sometimes houses, as a ritual of cleansing. The dating of these structures provides a revised climatic sequence for the plateau portion of the summer rainfall region. Among other new results, there was a drought at the end of the Mapungubwe period (ca. AD 1300). At about AD 1650, droughts associated with the arrival of maize caused people to stop growing it as food for a while. 相似文献

This paper is concerned with the historical dimension of the current debates on climate change, and argues that the history of the understanding of climate change has itself become part of the rhetorical account. Key historic moments of disclosure and revelation have become central to the ways in which climate change is presented as a persuasive narrative today. This paper takes a discursive approach to exploring the background of these signal moments in climate change history, and aims to show how they have helped to shape the terms of the current debate. 相似文献

Abstract: It has been argued that the preoccupation of individual nations with economic growth and development has contributed to environmental degradation. Economic nationalism is viewed as a hindrance to international strategies that can be used to slow the rate of environmental degradation. This paper argues that, in the case of Singapore, the means to mitigate environmental concerns are largely driven by material interests. Emissions control measures have been introduced provided they have been deemed economically feasible. But this has not prevented the city state from being a socially responsible member of the global community. This paper argues that, in today's context, policies that appear to be “nationalist” may not be totally inconsistent with policies that could help to improve the standard of living of all members of the international community. Selective engagement in regional and global initiatives realistically portrays the policy choices of many nation states. This paper contends that environment-related initiatives have to be seen in terms of reconciling the dual objectives of maximising the national interest and mitigating the global problem of environmental degradation. 相似文献

Both Canada and the United States have “pivoted” toward Asia in their foreign policy over the past decade, although emphases in those pivots differed between the two countries. The former focuses on an economic pivot initially, the latter on a security one. What factors explain these shifts? What was the magnitude of policy change by both? Utilizing some important theoretical works by Charles Hermann, we discuss the factors that appear to have brought about this policy change toward Asia, outline the actions and activities that both countries have initiated toward Asia in the past decade to illustrate the type and magnitude of policy change that has occurred, and compare some areas of political, economic, and military similarities between Canada and the United States toward this region. Finally, we assess the likely future of these pivots to Asia in light of the change in political leadership within both nations. 相似文献

In spite of recent advancements regarding regional innovation policy rationales and evidence, there are few analyses about the actual features of existing regional innovation policies. Nevertheless, a policy analysis perspective is important in order to recognize their distinctive patterns across regions, and to understand how rationales and evidence can be translated into policy-making. To this purpose, this paper develops a framework to study the extent to which regional innovation policies have changed during the past few years. Since the mid-2000s, there has been an important development of innovation policy rationales, advocating for more specialization; likewise, greater data availability at the regional level has allowed more sophisticated assessment of innovation performance. Finally, the crisis since 2008 has had ravaging effects in some regions, with job losses and severe economic sluggishness. Therefore, it is reasonable to expect transforming dynamics in regional innovation policies. Against this backdrop, the paper compares the institutional frameworks and budgetary priorities of four Spanish regions during the period 2001–2014: Catalonia, the Basque Country, Galicia and Andalusia. In so doing, it aims at studying the extent to which regional governments have readily addressed past and new challenges related to their regional innovation system, and if so, how. 相似文献

This paper examines regional, ethnic-specific patterns and individual-level correlates in same ethnic marriages (endogamy) and ethnic intermarriages in Indonesia. With data from over 47 million couples in prevailing marriages from the full enumeration of the 2010 Census, we outline the provincial variations in endogamy against development indicators and an ethnic fractionalisation index. We compare the prevalence of endogamy for major ethnic groups, and use network plots to examine pairing patterns in ethnic intermarriage. We use multivariate analysis to summarise the relationships between the likelihood of endogamy and migration status, ethnic group size, age group, and education for individuals in two selected provinces: North Sumatra and Jakarta. There is evidence to support negative associations between endogamy rates and provincial development indicators. Endogamy rates vary across major ethnic groups, and as expected, are higher in relatively large ethnic groups. In Jakarta and North Sumatra, individuals in urban areas, with younger age, and higher level of education have lower likelihood of endogamy. We found a positive relationship between ethnic size and endogamy, but conflicting results on the association between lifetime migration and endogamy in both provinces. By studying ethnic pairing patterns, this research provides a unique window to understand the dynamics of development, social change, and social stratification in an ethnically diverse emerging democracy. 相似文献

Archaeologists can learn from models of evolution as a self-organized critical phenomenon. Self-organized critical systems are large, interactive systems that organize into a critical state where minor events can trigger chain reactions. Such systems demonstrate power-law distributions in the size of changes, or avalanches, that occur. The theory of self-organized criticality is important in that it implies that the evolution of complex systems may be driven more by interactions between agents than by external events or natural selection. Stylistic changes may be examples of avalanches of interconnected events. Evidence for self-organized criticality is shown for stylistic evolution in historical pottery styles from New York State and is used to evaluate the nature of a prehistoric pottery typology from the Southwest. 相似文献

“杨各庄”等地名的地理分布及其音变的历史意义 总被引:1,自引:0,他引:1
华北地区及华东地区地名中多见“X各庄”和“X家庄”。该地区中,从西北部到东南部,“X各庄”的比例逐渐增多,而“X家庄”的比例逐渐减少,形成了一个语音渐变的地理连续体。这种特殊现象的形成是由于该地区西北部较频繁地受到北方阿尔泰语系诸语言的影响,而相对来说,东南部则较少受到这种影响。地名中的“各”仍然保留了中古汉语“家”的舌根音塞音声母[k-]。这种明显的地域互补分布表明了北方汉语方言前高元音前面的舌根声母转变为舌面音的力量来自于外部的人文影响,而非内部语言音变。 相似文献
