The aim of this study was to image buried remains and appoint buried Hellenistic street system, and identify minerals and rock types of the ancient city of Nysa, one of the most important historical sites of Turkey. This study used polarized microscope and confocal Raman spectroscopy (CRS) ground penetrating radar (GPR) method, to identify the buried remains, rock types and minerals. 相似文献

“九·一八事变”前后,蒋介石推行“攘外必先安内”的反动政策,国家民族危在旦夕。刚辞去国民政府交通部次长而“称病”闲赋苏州的李仲公,向蒋介石提出“联共抗日”主张,并提呈具体“方案”,受到蒋介石的重视并约见商谈,虽然蒋介石从同意其主张到反悔,李仲公却成为国民党内最早提出“联共抗日”主张之人。此时,李仲公译著出版的《日本帝国主义的满蒙观与我们的驳议》一书,成为爱国知识分子拍案而起的抗日先声。 相似文献

Enhanced transportation infrastructure improves the frequency of travel and facilitates face-to-face communication. Will the resulting reduction in travel cost mitigate the geographical concentration of knowledge spillovers? Our empirical strategy exploits China's mass expansion of its intercity high-speed railway network as a natural experiment. Using patent citations as the proxy for knowledge spillovers, we find inventors increasingly rely on more distant knowledge after rail connection and newly connect cities' innovation performance improves substantially. 相似文献

Organised, temporary labour migration from the Global South to wealthier countries is a growing and sometimes problematic phenomenon. This article considers Timorese involvement in the Australian Seasonal Workers Program (SWP) in relation to this trend. Drawing primarily on semi-structured interviews and participant observation undertaken among an interconnected group of 50 Timorese seasonal workers across Australia and Timor-Leste between 2016 and 2021, we found that geographical and social isolation and limited leisure all proved challenges while working in Australia. In some cases, it appears that the workers were able to lean upon their own social networks and local churches as a way to mitigate these challenges. We argue that, in considering the welfare of workers in temporary migration programs such as the SWP, it is important to be aware of the role played by informal groups that are formally outside the scheme itself. 相似文献

The effects of knowledge spillovers from neighbouring regions on regional industrial diversification should not be overlooked. Here we are referring to not only intra‐industry knowledge spillovers from neighbouring regions, but also the spread of knowledge from related industries in neighbouring regions. This paper also develops an analytical framework that pays more attention to the role of institutional proximity between regions and how it is associated with geographical and cognitive proximity, and acknowledges that institutional proximity may generate asymmetric effects in the process of inter‐regional knowledge spillovers. Using the Chinese custom database during 2002–11, we confirm that knowledge spillovers from neighbouring regions play a key role in regional industrial diversification. More importantly, inter‐regional knowledge spillovers are likely to occur more efficiently if two regions have similar institutional contexts. It is also shown that institutional proximity could generate asymmetric effects in inter‐regional knowledge spillovers. 相似文献

Disciplines such as Geography are well placed to respond to the changing needs of society and the effective application of geographical knowledge to real-world problems. This project surveyed first year Geography undergraduates’ understanding of “What is Geography?”, both before and after an exercise in which geographic topics were identified within recent newspapers. The survey instrument employed was an anonymous, self-administered questionnaire, and was undertaken with first-year undergraduate Geography students at a university in South Africa. Results show that the exercise enabled students (n = 158) to more readily see the application of geographical knowledge to both environmental and social problems that they identified in the newspaper stories. Students also identified that studying Geography may be able to help them increase their skills, employment prospects and earning potential. These findings can help locate the disciplinary concerns and applicability of Geography in post-apartheid South Africa within the wider context of the twenty-first Century world. 相似文献

Critical physical geography (CPG) calls for integrative research on material landscapes and the socio-political dynamics of scientific knowledge production. Network analysis, a rich tradition of tools and approaches for analyzing relational information, has seen little use in the CPG literature to date. This represents a fruitful opportunity, as many of CPG's core interests—knowledge politics, histories of scientific concepts, and ecosocial relations—can be effectively analyzed using network techniques. In this article, I argue for adapting network approaches to CPG. First, I provide an overview of various network concepts, approaches, and their origins. I then discuss bibliometric network techniques for “science mapping” including co-word, co-authorship, and citation analyses. Next, I describe discourse network analysis, a recent mixed-method approach from political science. Finally, I discuss overlaps with emerging approaches from qualitative and visual network analysis. In each section, I provide existing and hypothetical examples, as well as software and visualization techniques, that demonstrate how network approaches could add new insights to CPG and related scholarship. Linking CPG with the diverse traditions of network analysis has the potential to produce new empirical understandings and bring the field into conversation with a growing body of research that spans the social sciences, natural sciences, and humanities. 相似文献

明清时期国家对于汉水下游的水利管理制度经历一个变迁的过程,与这一区域的水利问题的日益突出密切相关,垸田的发展以及带来的问题是主要的因素。钟祥至沙洋的汉江干堤极易溃决,并且关系到整个下游地区的安全,因此在人力组织、资金筹集、岁修维护上,国家的政策表现出明显的倾斜性,相对于沙洋以下的区域,给予了充分的重视。沙洋以下,天门、潜江、沔阳等州县所在区域主要以垸田为主,国家将这一区域的堤防修筑与维护主要交由地方来进行。垸堤岁修维护采取堤甲制的组织形式,由垸民完成,一方面没有固定的资金,另一方面在正常年景之下,垸民可以获得基本的物质生存,因此垸堤的维护面临相当的困难。 相似文献
