Strategies for Teaching Maritime Archaeology in the Twenty First Century

Maritime archaeology is a multi-faceted discipline that requires both theoretical learning and practical skills training. In the past most universities have approached the teaching of maritime archaeology as a full-time on-campus activity designed for ‘traditional’ graduate students; primarily those in their early twenties who have recently come from full-time undergraduate study and who are able to study on-campus. The needs of mature-age and other students who work and live in different places (or countries) and therefore cannot attend lectures on a regular basis (or at all) have largely been ignored. This paper provides a case study in the teaching of maritime archaeology from Australia that, in addition to ‘traditional’ on-campus teaching, includes four main components: (1) learning field methods through field schools; (2) skills training through the AIMA/NAS avocational training program; (3) distance learning topics available through CD-ROM and using the Internet; and (4) practicums, internships and fellowships. The author argues that programs to teach maritime archaeology in the twenty first century need to be flexible and to address the diverse needs of students who do not fit the ‘traditional’ model. This involves collaborative partnerships with other universities as well as government underwater cultural heritage management agencies and museums, primarily through field schools, practicums and internships.     

《从巴黎到伯尔尼》:恩格斯的一份社会调查

对原始献和目击记录进行认真的分析,以便深入了解历史事件与人物的真实面目,这是历史科学的传统。恩格斯的《从巴黎到伯尔尼》正是一篇具有珍贵的社会史史料价值的目击记录。在这篇未完成的手稿中,恩格斯给了法兰西有关地区的风土人情以较好的评价。它是当时法国的社会情景、民间心态与自然风貌的写真,是后人研究法国近代历史的宝贵资料。     

博物馆文物的防震保护研究（三）——陈列文物的地震安全性分析

通过分析博物馆馆藏文物的悬吊、固定、浮放等基本放置形式,探讨了文物的陈列特征及其可能造成的震害因素。综合考察和分析研究了国内外浮放式物体及陈列文物的运动状态,指出陈列文物在地震发生时的主要危害性运动是滑移和倾覆。根据相关浮放物在地震作用下的计算方法、上海博物馆文物的陈列特征及防震设计参数,提出简便实用的浮放式陈列文物稳定性计算模型,编制了适合上海博物馆文物安全性分析的计算程序。并以上海博物馆文物陈列的3类接触材料、4楼中国古代玉器馆的典型陈列文物为试点,计算了陈列文物在地震中遭受破坏的临界值。表明在设防水准的大震和中震情况下,目前陈列现状的绝大多数文物均存在倾覆和滑移安全隐患,但当文物所受到的地震动减小到110gal时可满足陈列安全。     

An investigation of soil phosphorus distribution within occupation deposits from a Romano-British hut group

A simple scheme for soil sampling and subsequent analysis for total soil phosphorus using perchloric acid digestion is described and its application illustrated by samples from the native farmstead of the Roman period at Cefn Graeanog in North Wales. The floor deposits of three distinctive buildings were analysed, and the data obtained enhanced by Trend Surface Analysis to produce generalized maps of the phosphorus distribution, together with levels of significance of such distribution patterns. These were then used to clarify the details of the interpretation of the usage of the various types of building. Data for soil phosphorus concentration clearly reveal the pattern of erosion of constructed floors, the presence of features such as hearths and drains, and can be used to reveal patterns not otherwise discernible by excavation techniques.     

Phosphatic mineralization of seeds from archaeological sites

Recent investigations of botanical material from archaeological sites have provided seeds and plant remains exhibiting a crystalline or semi-crystalline appearance. X-ray diffraction and partial chemical analysis have revealed that the particular plant materials had been replaced by calcium phosphate. Using systematic sampling and retrieval techniques a significant body of data has been accumulated. Most mineralized botanical evidence has been recovered from faecal deposits, in particular cess pits and garderobes, and has provided an important source of information about aspects of diet of past populations.     

Indigenous Methodologies: Suggestions for Junior Researchers

Indigenous methodologies in geography have recently been developed to decolonise Western dominated paradigms. It has been argued that research which does not benefit Indigenous communities should not be conducted. However, Indigenous methodologies are not taught in many post-secondary institutions. Therefore, when they pursue Indigenous topics, many junior researchers are self-taught in these methodologies. However, these methodologies cannot be defined simply and they are too diverse to be learnt in a short period. In Japan, Indigenous peoples are not widely recognised and research on contemporary Indigenous issues is limited. The concept of Indigenous methodologies is rarely discussed. Because of this, Japanese researchers rarely identify their research as adopting an Indigenous methodology. Indigenous researchers are thereby discouraged from pursuing Indigenous methodologies. Furthermore, a methodology or a thesis statement used by researchers to reflect Indigenous perspectives often gets little support from Indigenous peoples. My master's research on the Ainu mirrored this situation. While Indigenous methodologies remain difficult to learn, junior researchers should not be discouraged from this form of engagement. Practical suggestions are therefore necessary to encourage their use and application. Based on my experience, I suggest that researchers approach Indigenous communities from a learning perspective. This would encourage open-mindedness and sensitivity. Researchers should also be prepared and willing to refine their research questions and to continue their literature searches after their fieldwork is completed. These strategies could limit misinterpretation and exploitation of Indigenous knowledges and peoples.     

How Chinese scholars think about Chinese foreign policy

China’s assertive diplomacy in recent years has ignited intense debates among international relations (IR) scholars. Some argue that China’s assertive behaviour is rooted in its perception of increasing power and capabilities. Others suggest that it is US policies that triggered China’s assertive reactions. Relying on an original survey of China’s IR scholars conducted in Beijing in 2013 and using structural equation modelling, we empirically examine Chinese IR scholars’ attitude towards Chinese power versus the United States, their perceptions of US policy in Asia, and their preference for an assertive Chinese foreign policy. We find that both the power perception and policy reaction arguments make sense in accounting for Chinese IR scholars’ attitude regarding China’s assertive diplomacy. However, our research suggests that a more pessimistic view on Chinese power is more likely to be associated with a preference for an assertive foreign policy.     

Age‐at‐death assessment using the os pubis and the auricular surface of the ilium: a test on an identified Asian sample

This paper reviews the results of blind tests of two morphological methods of age‐at‐death estimation. These tests were performed on a known age‐at‐death and sex sample taken from a collection of a Thai population. The first technique is based on the age related changes of the pubic symphysis according to the Suchey‐Brooks system, and the other concerns the metamorphosis of the auricular surface of the ilium elaborated by Lovejoy and colleagues. This is the first time that these methods have been tested on skeletal material from Asia. The results indicate that, for both methods, bias and inaccuracy increase with age and true age tends to be underestimated. As a consequence, age‐at‐death assessment based on these two techniques should be avoided on Asian archaeological series or forensic cases. Copyright © 2004 John Wiley & Sons, Ltd.
