The Huizhou Documents are a precious repository of historical memory and they have gradually been collected since 1946. This archive dates from the Southern Song period to 1949, and its content is distinguished by its continuity, specificity, accuracy, and representative nature, all of which make these documents extremely enlightening for scholars. Systematically collecting, organizing, categorizing, and utilizing these documents has not only given birth to a new field, Huizhou Studies, but has also provided valuable material in support of research on politics, the economy, law, education, and the civil examination system in late imperial China.  相似文献

This paper contributes to debates about the globalisation of higher education by providing a pioneering geographical exploration of Chinese–foreign cooperation in running transnational higher education, or TNHE, programs. Departing from widespread neoliberal and postcolonial critiques of TNHE, which tend to emphasise liberal market forces and Anglo-American hegemony in the circulation of academic knowledge, our study examines how the Chinese state’s developmental targets, strategic policies, and political–ideological considerations have shaped the evolutionary trajectory, geographical distribution, and cross-border connections of China’s TNHE programs. We demonstrate that the place-based development of TNHE is mediated by governments’ interventionist policies and embedded in existing higher education regimes, especially in the context of East Asian developmental states. By maintaining a higher education system dominated by public universities and by being the ultimate examination and approval authority, the Chinese government both determines the status of TNHE in the national higher education system, constrains the typologies and sources of knowledge flows, and shapes the national landscape of TNHE development. The territorial geographies of TNHE thus reflect complicated interactions between the state and the market, the global and the local, and economic and political/cultural forces.  相似文献

The punctuated equilibrium theory (PET) shows that government policy is mostly stable with occasional drastic change, which scholars attribute to institutional friction and limited information processing capacity. Although the existing PET literature predominantly focuses on democracies, scholars have started to apply the theory to authoritarian countries. Autocracies are a fertile testing ground for the theory's underlying mechanisms because they appear to experience less institutional friction but more informational restrictions than democracies. However, PET studies on autocracies are still rare. To deepen our understanding of the PET and the policy process beyond democracies, we conduct a systematic review of 88 Chinese language PET journal articles. We show that Chinese language PET research is increasing. Contrary to the English language PET literature, most Chinese studies are qualitative, while a key similarity is the weak operationalization of PET core concepts. The reviewed studies confirm a punctuated equilibrium pattern of policymaking in China but provide only limited evidence for more intense punctuations compared with democracies. Future PET research on China ought to use long-term data sets and examine institutional friction and information processing by policymakers. We also argue for more international exchange and comparative research to advance our understanding of the policy process in China and other autocracies.  相似文献

In archaeology, strontium isotope analysis is developing into an efficient scientific technique for tracing the movement of prehistoric humans and animals. Determining the local bioavailable 87Sr/86Sr ratio range is the key to distinguishing whether the human or animal is indigenous to the local area. It has been shown that the 87Sr/86Sr ratio in the enamel of pigs can be an excellent sample to determine the range of local strontium isotope ratio at the site. However, pigs may not be all local at the site, and there is no special study on whether pigs’ different ages and tooth types impact the local strontium isotope characteristics. In this paper, the tooth enamel of 19 pigs from the Zaoshugounao site for strontium isotope ratio (87Sr/86Sr) by multicollector–inductively coupled plasma mass spectrometry. There were no significant differences in 87Sr/86Sr ratios of local pigs at different months and different molar types, which did not affect the determination of the local strontium isotope standard. Based on the local strontium isotope ratio range (0.711056–0.711476), we found that five pigs were non-local. The Jing and Wei river basins (in Guanzhong basin) and northern Shaanxi are likely sources of non-pigs.  相似文献

Trace element compositions of 25 shards of Chinese Late Ming export blue-and-white porcelain from Zhangzhou and Jingdezhen kilns are analysed by Inductively Coupled Plasma Mass Spectrometry. Principle components analysis and REE distribution curves are used to establish method for provenance unknown Chinese export blue-and-white porcelain which may have originated from Zhangzhou or Jingdezhen kilns. By matching the REE distribution curves of Zhangzhou kiln samples and parent rocks of the possible clay sources used to make Zhangzhou blue-and-white, and comparing it with previous results of geological, geochemical and archaeological researches, the clay used for producing Zhangzhou export blue-and-white has been identified as having been collected from the weathered shells of a nearby potassium feldspar miarolitic granite outcrop.  相似文献

The initial Late Paleolithic, said to appear between 40 and 30 kya in eastern Asia, is defined by the appearance of many innovations. These archaeological indicators include the appearance of more refined stone tool making techniques (e.g., include the appearance of blade and microblade technology), complex hearth construction, use of pigments and personal ornamentation, as well as worked faunal implements such as bone and antler tools. We report here new findings from a multidisciplinary research project conducted at the Shuidonggou (Choei-tong-keou) site complex in northern China, a series of localities that date from the initial Late Paleolithic to the Neolithic.  相似文献
