吉林省通化市自安山城调查报告

2004年,吉林省文物考古研究所、通化市文管会办公室联合对通化市自安山城进行了考古调查与测绘工作,发现了城墙、门址、供水及排水设施、房址等遗迹,对这些遗迹进行清理又发现了一些陶器、铜器、铁器等遗物。自安山城是汉高句丽时期一座重要的城堡,应该是西汉时期的玄菟郡。     

论中国信息化的路径选择

十六大针对我国国情以及世界信息化的现实。提出了以信息化带动工业化的新型工业化道路。我国是在工业化尚未完成的条件下推进信息化的,要实现信息化带动工业化的目标,笔认为必须了解并正视中国信息化的初始条件,例如,生产力水平落后且呈现多层次性、产业结构不合理且第三产业的比例偏小、经济制度和经济体制亟待变迁、化变革不到位、政策法规不完善、教育水平低等。努力避免由于这些初始条件引起的路径依赖而产生的锁定。笔认为,为了避免锁定,作为政府应提高认识,关注长远与差别;重视发挥市场的主导作用;突出重点,发挥比较优势;扬长避短,处理好发展高新技术产业和传统产业的关系,资金技术密集型产业和劳动密集型产业的关系,信息技术的引进与开发的关系,只有这样才能使我国信息化进程顺利进行。

宁夏彭阳姚河塬遗址Ⅰ象限北墓地M4西周组墓葬发掘报告(上)

姚河塬遗址位于陇山东侧泾水流域上游,宁夏彭阳新集乡东北5公里处的黄土塬地上,遗址南北两侧分别有红河的支流李儿河、小河流过,并在遗址东侧交汇,形成一处三角台塬地.遗址区北以李儿河南岸塬地的断崖为界,南抵小河北岸的塬地断崖,西至一条南北向自然冲沟为界,东到塬地尽头的断崖边,并部分与小河湾战国秦汉遗址相交错,遗址面积92万平方米(图一).     

香港西贡沙下遗址DI区发掘简报

2002年春,香港古物古迹办事处与广州市文物考古研究所在香港西贡沙下遗址DI区进行考古发掘,面积1000平方米。发掘新石器时代晚期、商周时期和宋代文化层,清理了石器制作场、墓葬、灰坑及柱洞等遗迹,出土大量石制品和陶器,还有少量汉、宋、明、清时期的遗迹和遗物,为研究香港及珠江三角洲地区考古学文化的序列提供了宝贵的资料。     

鄂尔多斯地区近代移民研究

清代以来。内地的人口不断增长。人地矛盾日益突出。晋、陕地区的人口大量迁往鄂尔多斯地区,对该地区的经济发展、人口分布、社会结构及民族关系等方面都产生了深远的影响,对边疆的巩固起到了一定的作用。     

东魏肆州长城

《魏书·孝静帝第十二》载：“武定元年秋八月,……,齐献武王召夫五万于肆州北山筑城,西自马陵戍,东至士 。四十日罢。”这条著名的长城,不少史家有过著述,却未能超越《魏书》所记,寥寥数语,难详其明［１］。近人亦著文理论,仍拘泥于文献,只作大概的推测～［２］。肆州长城究竟分布于什么地方,现存情况怎样,仍然是个谜。２０００年夏天,在国家文物局文物地图总编委的指导下,山西省文物局长城考察组对该段长城进行了实地勘察,现将勘察结果作一简要汇报。 一、肆州长城构筑背景 北魏永熙三年（５３４年）,高欢兵逼洛阳,赶跑…     

Safe Space: Towards a Reconceptualization

The term “safe space” dates to the late twentieth century women's movement, but it has since been used in many different contexts. In this paper, we review and analyze historical and contemporary “safe spaces”. These include “separatist” safe spaces in women's, anti‐racist, and feminist communities, “inclusive” safe space classrooms, and safe spaces in which (non‐human) objects are central. We argue that safe spaces should be understood not through static and acontextual notions of “safe” or “unsafe”, but rather through the relational work of cultivating them. Such an understanding reveals several tendencies. Namely, safe spaces are inherently paradoxical. Cultivating them includes foregrounding social differences and binaries (safe–unsafe, inclusive–exclusive) as well as recognizing the porosity of such binaries. Renegotiating these binaries is necessarily incomplete; a safe space is never completely safe. Even so, we encourage the critical cultivation of safe space as a site for negotiating difference and challenging oppression.     

Cutwaters Before Rams: an experimental investigation into the origins and development of the waterline ram

Students at Stevens Institute of Technology (Hoboken, NJ, USA) investigated the reasons for an elongated projection at the bow of Mediterranean galleys. Using a 1:20 base model adapted from the Trireme Trust's Olympias fitted with: 1) an elongated projection; and 2) a control bow similar to excavated merchant ships, tow‐tank tests were carried out at various speeds. Hydrodynamic resistance and power were calculated for each bow type. Above speeds corresponding to 6 knots, the cutwater bow significantly attenuated the model's bow waves when compared to the control bow. These results were then compared to those of the ship with a ram‐type bow from experiments conducted in 1985 at the National Technical University of Athens, which showed similar wave‐attenuating characteristics.
