Adaptations and Dispersals of Anatomically Modern Humans in the Changing Environments of North Africa: the Contribution of Microvertebrates

There is limited available data on the environmental context of the arrival of the first anatomically modern humans (AMH) in North Africa, and subsequent Paleolithic and Neolithic occupations within this region. Microvertebrates such as rodents, shrews, amphibians, and squamates are known to be good indicators of climate and landscape changes. They also represent continental paleoecological records that can be directly related to human occupations. Moreover, faunas and humans have been subjected to several dispersal waves through similar routes, and some rodents may present anthropophilous behavior. Therefore, by understanding the dispersal pattern and pathways of these microvertebrates, it is possible to propose scenarios for human dispersal events. In this study we took the rich microfaunal assemblages from the Témara region, Atlantic Morocco (El Harhoura 2 and El Mnasra Caves), and placed them within a broader synthesis, in order to highlight the role of microvertebrates in providing a better understanding of the human-environment relationship during the Late Quaternary in North Africa.     

The Pleistocene of Rabat (Morocco): Mollusks,Coastal Environments and Human Behavior

The Rabat-Témara region of the Moroccan Atlantic coast reveals a succession of Quaternary palaeobeaches. This coastal area is dotted with numerous prehistoric caves. The study of the Upper Pleistocene coastal landscape associated with these caves is of paramount importance in the knowledge of human population subsistence. During the Upper Pleistocene, the ocean level changes drastically influenced the coastal geomorphology as well as the fauna assemblages. The chrono-lithostratographical analysis of the coastal sedimentary formations allows the distinction of three sequences rich in marine fauna. These sequences date from MIS 11 to MIS 5. The identification of malacofauna species from these deposits revealed 39 species, along with Bryozoans, Crustaceans, and Echinoids. These assemblages show a constant fauna cortege highlighted by the dominance of the amphi-Atlantic species Stramonita haemastoma. This species shows an increase in the number of specimens in the uppermost part of marine deposits, probably in relation with a climate warming in the MIS 5. This fauna of both intertidal rocky substrates and sandy substratum indicates environmental conditions close to the present-day Rabat-Témara coastline. As in other coastal locations of Africa from MIS 5, the Middle Stone Age Homo sapiens population benefitted from a littoral environment rich in coastal resources. Comparison between thanatocenoses and archaeological records allows us to identify both species available for Middle Stone Age population and those preferred for human use.     

“长江口二号”沉船出水青花瓷中的污染物研究

位于长江入海口的“长江口二号”清代沉船是中国目前发现的保存最为完整的古代木制沉船之一，已于2022年11月完成整体打捞。在进行水下考古调查时，沉船出水的部分青花瓷出现的病害现象引起了考古工作者的关注，特别是裂纹中黑色污染物及表面铁锈状污染物对文物的外观产生了很大影响。本工作选取了三件具有典型被污染特征的青花瓷标本作为代表，使用能量色散X射线荧光分析(EDXRF)、光学显微镜(OM)、X射线衍射分析(XRD)、拉曼光谱分析(Raman)和扫描电子显微镜-能谱分析(SEM-EDS)等方法，对污染物进行了研究，探讨了其形成原因以及环境的影响作用，并对其潜在危害进行了分析。研究表明，污染物主要以方解石、菱铁矿等碳酸盐以及铁的氧化物、氢氧化物和硫化物为主。长期处于河口淤泥中的还原性环境是导致菱铁矿和亚稳的铁硫化物形成的原因，船体中铁质构件腐蚀对局部环境的污染是重要的影响因素，这也反映出被污染的青花瓷所处位置和环境的特殊性。出水的部分青花瓷釉中裂纹的形态表明其形成是由物理撞击造成，而釉中硅灰石晶体的选择性腐蚀会导致腐蚀坑的形成，裂纹和腐蚀坑均为外部污染物进入釉层内部提供了通道，导致瓷器劣化。出水后...     

Einstein et «Zweistein»

As the sobriquet «Zweistein» suggests, within the theoretical physics community Wolfgang Pauli came to be regarded as second in eminence only to Albert Einstein. Over a period of thirty-five years, they interacted both intellectually and personally. This paper focuses on four interrelated topics of their discussions. 1) The theory of relativity: at the age of twenty, Pauli prepared the definitive survey of relativity, a survey which he revised near the end of his life and which remains invaluable to physicists and historians of physics. 2) Unified field theories: although initially sympathetic to Einstein's search for a unified theory of electromagnetism and gravitation, and having made important contributions to the subject, Pauli came to regard such efforts as fruitless. 3) Foundations of quantum mechanics: Pauli's negative evaluation of Einstein's program grew out of their sharply differing evaluations of the role that quantum mechanics would play in the future, development of theoretical physics. 4) Quantum gravity: Pauli recognized that, until the achievement of a successful reconciliation of quantum mechanics and general relativity — an achievement that still eludes us — Einstein's challenge to quantum mechanics could not be laid to rest.

湖北荆门左埭楚墓群出土金属器研究

利用XRF、金相显微分析等手段对湖北省荆门市境内左冢楚墓群出土的金属器,特别是青铜器进行了测试分析,XRF分析表明该楚墓群出土的青铜器多为铜、锡、铅三元合金,且容器的锡含量低于兵器和工具,而铅含量则相反。金相分析显示左冢楚墓群出士青铜器多为铸造组织,其中3件铸后经过不同程度的加热：而热锻成形的器物有4件,其中有一件在锻后进行了冷加工。结果显示,此批青铜器合金成分比较科学、制作工艺比较先进。     

Imperial power, gentry power and clan power: Western and Chinese cultural traditions in a comparative perspective

The differences between China and Western countries in human and physical environment has brought about two distinctive models of state. In the Chinese-style state of quasi-consanguinity, in which family and state have a similar structure, imperial power, gentry power, and clan power are the product of common ownership of consanguineous groups. The similarity in the structures of these three kinds of power derives from the fact that they are all restricted by the power of lineage generated from the self-sufficient small farmer economy, and must obey the conventions of ancestors which hold the benefits of the group as supreme. The relationship between these three kinds of power, is definitely not the one that is based on the division of power that is founded on individual private ownership in Western countries, where ‘public power’ and ‘individual private ownership’ are antithetic, but are three aspects of the patriarchal dictatorship that complement each other. Therefore, village rule in China and autonomy in the West are two totally different concepts, and gentry power is also not the ‘authorized power’ from the state. __________ Translated from the Journal of Tianjin Normal University, 2004: 1
