二十世纪有关纸的考古发现不能否定蔡伦发明造纸术（1）

近几十年来,我国考古工作曾先后在一些西汉遗址和墓葬中发现了若干纸状残片,于是引起国内外许多学和广大人民的关注和提出疑问。是否蔡伦前约二百年就有了纸?造纸术还是不是蔡伦发明的?新发掘的纸状物到底是个什么样?经对历次的发掘作了详细的调查研究和分析化验,结论认为：20世纪有关纸的考古发现不能否定蔡伦发明造纸术。     

Memory,Identity and Aspiration: Early Modern Jewish Maps of the Promised Land

In the sixteenth century Jews began to produce maps showing the Exodus to the Promised Land. My aim in this article is to show that, through unique compositions of written biblical references and pictured symbolism (both Jewish and Christian), maps such as the Mantua map (1560s) and, a century later, the Amsterdam Haggadah [Passover] map (1695) were a means of constructing Jewish cultural memory and identity in the Diaspora and fostering aspiration for a second salvation through a return to Zion. I also explore the Jewish approach towards the biblical land as this was reflected in the maps.     

Development Thinking—Bridging the Gap Between Theory and Practice

Theoretically, Development Studies has been claimed to be moving out of its previous impasse. However, its policy implication has traditionally been rather weak, and on this account no large improvements are presently visible. A strong call for relevancy has emerged in the middle of the 1990s, from the same writers who claim that we are now moving beyond the impasse in development theory. Somehow this opens up a niche for development geography, if its strong background in field work can be combined in a dialogue based on theoretical issues. This paper illustrates how the teaching of development in the field can bring up new issues, to be discussed thoroughly within some kind of a dialectical dialogue. The teaching of development finds itself trapped in a controversy, that could be termed as a development crisis. However, existing contradictions in the debate can nurture the more intense probing into the nature of development. Combined with field work experience, this paves the way for a dialogue in which many of the axiomatic truths are turned upside-down. Matters—such as the conflict between modernization and traditional values, the meaning of development, and the role of various actors in the development process—are all focused in an intensive discussion.

试析马来西亚华人母语的转移现象

根据在马来西亚进行的实地调查所得到的数据和实例，以马来西亚五大方言群体为基础，逐一分析福建、广东、客家、潮州和海南方言群体中，相同家庭里祖子孙三代的母语种类和数量变化。研究证实，马来西亚华人的母语从方言逐渐转向英语和华语，开始摆脱原有籍贯的方言痕迹。

The Dynamic Behavior of the Basilica of San Francesco in Assisi Using Simplified Analytical Models

The Basilica of San Francesco in Assisi endured stronger earthquakes for centuries before 1997 earthquake, which generated the collapse of the two vaults. Experts blame as possible reasons of collapse the damage cumulated from previous earthquakes and/or the retrofitting made to the structure over its lifetime. This article presents the history of the retrofit interventions of the Basilica through the centuries, focusing mainly on the roof, which has been subjected to three major restorations through its life. It is shown using simple analytical models that the cumulative effects of the changes made to the roof of the Basilica affected the structure’s dynamic behavior in a negative manner, increasing the seismic loads on the existing structural members. In particular, the numerical results show that the 1958 roof intervention has stiffened the structure, redistributing the seismic loads on the façade and the transept. This overload might explain the collapse of the two Gothic vaults during 1997 earthquake.     

Simple Seismic Assessment of Traditional Unreinforced Masonry Buildings

A framework for quick seismic assessment and retrofit of traditional unreinforced masonry (URM) structures is presented. The proposed methods build on simple principles of structural dynamics and are used as an alternative to detailed time-history analysis, in recognition of the prevailing need for simple and practical methods, compatible with the low-budget and the limited level of knowledge regarding materials, internal force paths, connectivity and condition of older URM structures. An objective is to identify areas in the building that are particularly susceptible to damage and for guiding the types of the required global interventions to improve seismic response. Demand and supply are expressed in terms of relative drift ratios that quantify the intensity of out-of-plane differential translation and in-plane shear distortion of masonry walls. A characteristic traditional building type of timber-laced masonry is used as a model structure for illustration of concepts. The morphology and geometry of the building correspond to a statistical sample of the actual traditional unreinforced masonry buildings (TURM) found in historical centers of many towns in the greater region of Northern Greece. The methodology is particularly useful for setting retrofit priorities and management of the collective seismic risk of historical entities.     

Asymmetry of power and attention in alliance politics: the US–Republic of Korea case

While power asymmetry typically defines security relationships between allies, there exist other forms of asymmetry that influence alliance politics. In order to illustrate how they can shape policy outcomes that cannot be explained solely through the lens of power capabilities, the authors examine the role of relative attention that each side pays to the alliance. It is their central argument that since the client state has a greater vested interest in the alliance and given that attention depends on interest/need, the client state can leverage attention to get its way. By analysing two specific cases, the 2002 South Korean schoolgirls tragedy and the 2008 beef protests—instances where the South Koreans succeeded in compelling US concessions—the authors show that because the alliance was more central to the client state's agendas, there existed an asymmetry of attention that offered leveraging opportunities for the weaker ally. In this study, the authors emphasise the role of media attention as a key variable, and seek to contribute to debates on weaker party leverage in asymmetrical alliances.
