Africa's earliest bananas?

The recent discovery of banana phytoliths dating to the first millennium BC in Cameroon has ignited debate about the timing of the introduction of this important food crop to Africa. This paper presents new phytolith evidence obtained from one of three sediment cores from a swamp at Munsa, Uganda, that appears to indicate the presence of bananas (Musa) at this site during the fourth millennium BC. This discovery is evaluated in the light of existing knowledge of phytolith taphonomy, the history of Musa, ancient Indian Ocean trade and African prehistory.     

A new Palaeolithic discovery: tar-hafted stone tools in a European Mid-Pleistocene bone-bearing bed

Two stone flakes partly covered in birch-bark-tar and a third without tar on it were discovered in fluvial gravel and clay in central Italy, in association with the bones of a young adult female Elephas (Palaeoloxondon) antiquus and several micromammals. The probable chronology of the stone flakes is compatible with the late Middle Pleistocene suggested by the site's small mammals and geological context. The fauna indicates a cool stadial episode before isotope stage 6. That age means the flakes are the oldest ever found hafted with tar and indicate a greater capacity for late Middle Pleistocene hominins to utilize raw materials available during cold phases.     

古代西北疆域研究若干问题的思考

古代西北疆域是我国疆域的重要组成部分,对古代西北疆域的研究也是边疆史地研究中的重点之一。本文分析了西北疆域研究中应该注意的几个问题,认为以动态的标准确定我国不同时期的历史疆域是研究西北疆域的基本前提;西北疆域地位不断演变,是西北疆域变迁史的基本特点之一,也是西北疆域形成过程的基本形式。同时,文章还就民族、地理环境、国防安全等方面说明了西北疆域形成和发展的内在原因。     

"革命局"辨析

据苏俄、共产国际的有关档案记载。1920—1921年间在上海和中国其他几个大城市曾出现过“革命局”(ревбюоро)。对于“革命局”究竟是什么组织。目前已有几位党史学者发表了不同的意见,分别视其为:中共上海发起组及各地共产主义小组、社会主义者同盟的领导机构、具有统一战线性质的机构和俄共在华组织。这几种看法均值得商榷。从档案原文和“革命局”的名称、组织系统、自身结构与功能任务等方面来看,1920年夏成立于上海的“革命局”实际上是直属共产国际东亚书记处的具体负责中国共产主义运动的机构,而在其他城市的“革命局”则是设于上海的“中央局”的分支机构。虽然革命局后来的隶属关系、组织机构有所变化,但其作为共产国际的在华一级机关的性质却始终如一,在指导建立共产党、推动各革命团体的活动、实施共产主义宣传等工作上发挥了重要作用。随其主要使命的基本完成和中共的成立,革命局也归于消失。     

1939年秋-1940年夏国民党的南调命令及其影响——对皖南事变起源的新分析

抗战初期的南调命令是国民党在发展和维护它的华中敌后利益,尤其是大别山根据地利益的过程中提出来的.由于抗战的新形势,国民党对在失去大举"剿共"手段之后的策略选择和反共部署,其实并没有多少及时而深入的考虑,尤其因为共产国际五月指示以来共产党在华中采取攻势策略,国民党更显缺乏心理和策略准备,南调命令最终在国民党内外重重阻力下不了了之.但是,这并不意味着它在国共关系史上没有产生实际的影响.在皖南,国共都因为南调命令而发生了策略变化,两党由此不可避免地开始积累矛盾,直至事变发生.     

Landscape Archaeology of Nubia and Central Sudan

The paper examines the regional scale research in the Middle Nile Valley within the context of historical development of archaeology of Nubia and Central Sudan. This historical overview is put in the context of archaeological theory, especially the concept of landscape archaeology. A discussion of various theoretical issues is followed by the presentation of the natural, economic, political, cultural and sacred landscapes of Nubia and Central Sudan. Past field research is presented and the emerging trends are identified.La présente communication examine la recherche à l'échelle régionale dans la vallée du Nil Moyen dans le contexte du développement historique de l'archéologie de la Nubie et du Soudan central. Ce survol historique est situé dans le contexte de l'archéologie théorique, particulièrement l'archéologie du paysage. Une discussion des problèmes théoriques est suivie d'une présentation des paysages naturel, économique, politique, culturel et sacré de la Nubie et du Soudan central. Les recherches antérieures sont aussi présentées et les nouvelles tendances sont identifiées.     

Top-down or bottom-up: rural settlement and raised field agriculture in the Lake Titicaca Basin, Bolivia

Differing interpretations regarding the organization of past intensive farming are often distinguished as “top-down” or “bottom-up” perspectives. The development of intensive farming and its social organization are attributed to either nascent states and centralized governments or the incremental work of local communities or kin-based groups. We address the social organization of raised field farming in one region of the Lake Titicaca Basin of the Andean altiplano, Bolivia. We evaluate past research in the Katari Valley, including our own, based on recent settlement survey, excavation, and a variety of analyses. Taking a long-term perspective covering 2500 years, we find that relations of production and rural organization changed greatly over time in relation to changing sociopolitical conditions. Local communities played dynamic roles in the development and organization of raised field farming, yet its intensification and ultimate recession were keyed to the consolidation and decline of the Tiwanaku state. We conclude that the top-down/bottom-up dichotomy is overdrawn. Local communities and their productive practices never operated in a political or economic vacuum but both shaped and were transfigured by regional processes of state formation, consolidation, and fragmentation.     

Limb bones asymmetry and stress in medieval and recent populations of Central Europe

Monitoring the degree of asymmetry in different parts of the human body can contribute to population studies, as it may be connected indirectly with the social structure, living conditions, and also with biomechanical stress affecting the person. Analysis of asymmetry may also assess preferential use of the right or left of the body during specific activities. This study is based on the measurements of bones of the upper and lower limbs of skeletons derived from the remarkable medieval cemeteries of Mikulčice‐Kostelisko (78 male, 132 female) and Prušánky (66 male, 69 female) (9th–12th centuries AD), and a series of skeletons representing a recent population from Bohemia (143 male, 157 female). The objective was to assess directional asymmetry (DA), fluctuating asymmetry (FA) and antisymmetry (AS) of the dimensions of the evaluated bones, and to use these data to compare the characteristics of the medieval and recent populations. DA was recorded in most dimensions. In the upper limb, the humerus exhibited the greatest expression of asymmetry, and, with the exception of the clavicle, DA was always more pronounced on the right side. Conversely, DA was less prevalent in the lower limb bones. It was more pronounced on the transverse, sagittal and circumferential dimensions of the diaphyses and epiphyses than on the length, and in most cases it was on the left side. The FA values were very low, and almost negligible in relation to the size. Nevertheless, FA was markedly more frequent on the lower than on the upper limb. In contrast to the medieval population, the recent population had higher FA and DA values. Thus, we propose that people from this medieval population were subjected to lower developmental stress than the recent sample. Copyright © 2008 John Wiley & Sons, Ltd.     

"中国"与"天下"的重合——古代中国疆域形成的历史轨迹

“The Central Kingdom” is pregnant of political implications as well as of geographical and cultural significance. It was believed that whoever controlled Zhongguo (the Central Kingdom or China) would be the legitimate ruler over Tianxia (the realm under heaven or all under heaven). It was the contention for “the Central Kingdom” among the varieties of dynasties, notably those established by the Han-Chinese and the various ethnic groups in the northern borderland, that lead to the alternation of disintegration and unification of the territory. It was not until the Qing Dynasty that the unified “Central Kingdom” composed of a variety of ethnic groups turned into the ideal “realm under heaven” with “the Central Kingdom” at its core, which naturally put an end to the formation of territory in ancient China.
