明朝初年,国脉皆仰东南,为解决南方粮财物的北运问题,宋礼和白英受命组织修建了大运河山东段南旺分水枢纽。该枢纽主要包括引汶济运、导泉补源、设立水柜和置闸节流四个组成部分。其中,引汶济运是工程之重点,包括戴村坝、小汶河、南旺分水以及配套工程等四个子系统。这些水利设施组成一个和谐的系统工程,保证了该段运河的水量稳定充足,从而实现了大运河500余年的正常通行。南旺分水枢纽代表了我国古代运河水工的最高科学技术成就,堪称世界水利史上的一大经典范例。  相似文献

The school formal in New Zealand constitutes a rich site of analysis for researchers interested in gender and sexuality performances. As a social space, the formal both shapes bodies and is shaped by them. In this article, we explore the school formals of three different types of schools: a single sex girls’, a single sex boys’ and a co-ed. high school, all from an urban centre. Using the theoretical tools provided by poststructuralism and queer theory, we conducted a discourse analysis of observations conducted by the first author at two school formals, interviews with staff and students and interviews with peer researchers. We demonstrate how same-sex practices do not necessarily map onto queer bodies, masculinity onto ‘male’ bodies or femininity onto ‘female’ bodies. Such fluidity challenges the rigid heterosexual/homosexual and masculine/feminine binaries so that schools are more inclusive of gender and sexual diversity.  相似文献

This paper examines the role of accelerator programmes in promoting transnational entrepreneurship. Designed to assist the growth of start-ups by providing seed finance and structured entrepreneurship support, these programmes are now a prominent feature in many entrepreneurial ecosystems around the world. Drawing on in-depth qualitative evidence focused on one particular programme, the paper shows accelerators play an important intermediary or ‘brokerage mechanism’ providing start-ups with enhanced relational connections and networks. Transnational entrepreneurs attracted to these programmes are highly focused on exploiting these networks whilst maintaining multiple levels of embeddedness in various contexts to maximize the opportunities afforded by accelerators. While many governments are attempting to replicate accelerators programmes within the public sector, the paper concludes that such attempts may prove problematic within weaker entrepreneurial ecosystems.  相似文献

This study had two purposes. First, it empirically examined the relationship between citizens' participation in administrative policymaking phases and their perception of government transparency. Second, it investigated how citizens' use of both offline and online participation channels and their involvement in different phases of policymaking (i.e., agenda setting, implementation, and evaluation) were related to their assessment of transparency in government. A 2009 survey of residents of Seoul, South Korea, was used to test the study hypotheses. Using two‐stage least squares estimate techniques, the study found that citizens involved in any citizen participation programs are more likely than those not involved to positively assess transparency in government. With regard to the relationship between participation channels and transparency, citizens who used offline participation channels were more likely than nonusers to perceive enhanced transparency in local government. However, their use of online participation channels had limited effect on perceptions of transparency. Finally, participation in two phases of the policy process, agenda setting and evaluation, positively affected citizens' assessment of transparency in government.  相似文献

Between 1900 and 1970, American archaeologists perceived themselves as second-class anthropologists because the archaeological record suggested little not already known ethnographically, archaeology served anthropology by testing ethnologically derived models of cultural evolution, the archaeological record was ethnologically incomplete as a result of poor preservation, and archaeologists used but did not write anthropological theory. Ethnologists of the period agreed with these points and regularly reminded archaeologists of their limited role in anthropology. A few archaeologists claimed in the 1950s that archaeology could contribute to anthropological theory but they were ignored. The claim was reiterated by new archaeologists of the 1960s, and by the 1970s worries about the poor preservation of the archaeological record had softened. However, most archaeologists after 1970 (and before 1990) used anthropological theory and did not write new theory on the basis of archaeological data. The root cause of American archaeology’s ninety-year absence from anthropology’s high table of theory seems to be the discipline-wide retention of the ninety-year old belief that archaeology is prehistoric ethnology and the (unnecessary and constraining) corollary that archaeologists must use anthropological theory to explain the archaeological record.  相似文献

Many versions of the history of Americanist archaeology suggest there was a stratigraphic revolution during the second decade of the twentieth century—the implication being that prior to about 1915 most archaeologists did not excavate stratigraphically. However, articles and reports published during the late nineteenth century and first decade of the twentieth century indicate clearly that many Americanists in fact did excavate stratigraphically. What they did not do was attempt to measure the passage of time and hence culture change. The real revolution in Americanist archaeology comprised an analytical shift from studying synchronic variation to tracking changes in frequencies of artifact types or styles—a shift pioneered by A. V. Kidder, A. L. Kroeber, Nels C. Nelson, and Leslie Spier. The temporal implications of the analytical techniques they developed—frequency seriation and percentage stratigraphy—were initially confirmed by stratigraphic excavation. Within a few decades, however, most archaeologists had begun using stratigraphic excavation as a creational strategy—that is, as a strategy aimed at recovering superposed sets of artifacts that were viewed as representing occupations and distinct cultures. The myth that there was a stratigraphic revolution was initiated in the writings of the innovators of frequency seriation and percentage stratigraphy.  相似文献
