A MAZE OF TRANSPORTATION LINES IN TIBET

<正>In 2001,by chance I traveled along the road from Qinghai to Tibet. Though I did not experience the full length of this national road,I was very impressed by what I observed of Tibetan culture.Up to early 2007, I had entered Tibet eight times,from different directions through the four major access points:Sichuan,Yunnan,Xinjiang and Qinghai. Shouldering the responsibility of filming a documentary,I together with my colleagues in 2002 and 2004 drove a vehicle along the route from Sichuan to Tibet,but my third visit to Tibet was by myself.The route from Sichuan to Tibet     

变动中的家与地方:一个关联性的研究综述

家与地方的关系是地方性研究中的关键性命题。人本主义地理学认为地方根植是家的根本属性,批判地理学则从社会建构的角度阐释家与地方的动态关联。在全球化和灾害影响下,家与地方的联结方式不断变动,呈现出异常丰富的多样性。本文从理论脉络入手,对全球化进程中因绅士化引起的家的置换,无家可归与家在他乡,以及离散者的漂移之家等现象进行了分析;并从灾民自我调适行为和灾后重建计划的实施方面,讨论了灾害影响下家的重构与认同问题。相关学科和国际研究在这一领域的快速发展,将为国内社会文化地理学对家的探索创造良好的机遇。     

Iron and bronze production in Iron Age IIA Philistia: new evidence from Tell es-Safi/Gath, Israel

A metallurgically-oriented excavation in Area A at Tell es-Safi/Gath yielded evidence for iron and bronze production dating to the early Iron Age IIA. Two pit-like features, which differed considerably from one another in colour, texture and content, were excavated. Evidence shows that each feature represents a different in situ activity related to iron production, inferred by the presence of hammerscales, slag prills and slag. An upturned crucible was found on top of one of the features. Analysis of the crucible slag showed that it was used for bronze metallurgy. Tuyères, both round and square in cross-section, were found in and around the two features. The presence of the two industries together presents a unique opportunity to explore the relationship between copper and iron working. This is especially important against the background of the scarcity of evidence for iron production in the Levant during the early phases of the Iron Age.     

Stability of phytoliths in the archaeological record: a dissolution study of modern and fossil phytoliths

Opaline phytoliths are important microfossils used in archaeological and ecological research. Relatively little is known about the stability of phytoliths after burial. Under alkaline pH conditions they can dissolve, and mechanical disturbances can cause a loss of their more delicate appendages. Here we present an experimental study of phytolith stability (combination of solubility and abrasion). Modern and fossil phytoliths were extracted from wheat using new methods to minimize dissolution, and by burning in an oven. These assemblages were placed in a solution buffered to pH 10 and maintained under constant temperature and shaking conditions. The silicon concentrations in the solution were monitored once a week for 5 weeks. The phytolith morphologies in each assemblage were determined at the outset of the experiment and after 5 weeks. The results show that there are differences in stability between various assemblages. Modern inflorescence wheat phytolith assemblages are more unstable than those from leaves/stems. Burnt assemblages are less stable than unburnt assemblages, and a fossil phytolith assemblage about 3000 years old is more stable than the modern wheat assemblages. The results also show that individual phytolith morphotypes have different stabilities, and as a result of dissolution and abrasion, some morphotypes may resemble others. This study further shows that archaeological and/or paleo-environmental interpretation of phytolith assemblages may change with the assemblage’s state of preservation.     

Titus's Tinnitus

Historical approaches to tinnitus have depended highly on cultural factors. While ancient Oriental mysticism regarded it as sensitivity to the divine, Roman medicine associated it with depressive and seizure disorders on the basis of presumed common pathophysiology shared by the three conditions. In the Babylonian Talmud, tinnitus appears as Titus's curse: a gnat buzzing in the brain, responding to sound therapy, and then habituating. Various sources show varied emphases with common attention for contextual and emotional aspects that have become an important focus in modern management of tinnitus.
