The Making of Tupaia’s Map: A Story of the Extent and Mastery of Polynesian Navigation,Competing Systems of Wayfinding on James Cook’s Endeavour,and the Invention of an Ingenious Cartographic System

Tupaia’s Map is one of the most famous and enigmatic artefacts to emerge from the early encounters between Europeans and Pacific Islanders. It was drawn by Tupaia, an arioi priest, chiefly advisor and master navigator from Ra‘iātea in the Leeward Society Islands in collaboration with various members of the crew of James Cook’s Endeavour, in two distinct moments of mapmaking and three draft stages between August 1769 and February 1770. To this day, the identity of many islands on the chart, and the logic of their arrangement have posed a riddle to researchers. Drawing in part on archival material hitherto overlooked, in this long essay we propose a new understanding of the chart’s cartographic logic, offer a detailed reconstruction of its genesis, and thus for the first time present a comprehensive reading of Tupaia’s Map. The chart not only underscores the extent and mastery of Polynesian navigation, it is also a remarkable feat of translation between two very different wayfinding systems and their respective representational models.     

BOSERUP BACKWARDS? AGRICULTURAL INTENSIFICATION AS ‘ITS OWN DRIVING FORCE’ IN THE MBULU HIGHLANDS,TANZANIA

Why do farmers intensify their agricultural practices? Recent revisions of African environmental historiographies have greatly enriched our understanding of human–environmental interactions. To simply point at poor farming practices as the main cause of deforestation, desertification and other processes of land degradation is, for example, no longer possible. The contemporary analytical focus is instead on the complex and often unpredictable set of causal relations between societal, ecological and climatic factors. In the literature on agricultural intensification, conventionally defined driving forces, such as population pressure and market demand, remain important explanatory factors despite a growing body of research that suggests more dynamic scenarios of agricultural development and landscape change. This article reports on a case where the common‐sense logic of population pressure theory has dominated the historical narrative of a local process of agricultural intensification among an agro‐pastoral people in north‐central Tanzania. By way of a ‘detailed participatory landscape analyses’ a more complex and dynamic historical process of intensification is suggested, in which the landscape and the process of agricultural intensification itself are in focus. It is concluded that the accumulation of landesque capital has been incremental in character, and that the process of agricultural intensification in the study area has largely been its own driving force based on self‐reinforcing processes of change, and not a consequence of land scarcity and population pressure. This result demonstrates the possibility and usefulness of reversing the Bose‐rupian argument in analyses of agricultural intensification.     

DEMOGRAPHIC CHANGE AS A FUTURE CHALLENGE FOR CITIES IN EAST CENTRAL EUROPE

Contemporary cities in East Central Europe (ECE) represent a hybrid type of urban development which is still generally considered to be a special case and is only exceptionally referred to in the recently intensified debate over the European city. Our paper argues that such exclusion is short‐sighted because ECE cities face structural problems similar to those of their Western pendants. Therefore, the contextual frame of urban research needs to be widened and can no longer be restricted to post‐socialist transition. In this regard, one of the main challenges for future urban development will be the consequences of demographic change. Ageing, new patterns of fertility behaviour and more diversified household structures in line with the Second Demographic Transition (SDT) will have significant implications for urban structures and housing markets, as already known for Western Europe. The purpose of this paper is to work out new questions and hypotheses for future urban research with special respect to Polish and Czech cities. Besides West European experience, recent developments in eastern Germany are taken as a frame of reference, assuming that this specific transition case may, in many respects, be regarded as a forerunner for similar developments in its neighbouring countries.     

Nitrogen isotopes and the trophic level of humans in archaeology

Human and domesticate animal bone collagen δ¹⁵N values in prehistory differ generally by 3‰ or more from Neolithic to post- Roman times in Northwest Europe, leading to an assumed dietary animal protein fraction of 60–80% using a standard interpretation of δ¹⁵N values. We examine the assumptions on which this model rests and the limitations of our knowledge in the analysis of δ¹⁵N values in archaeology. We have developed a set of models which, with small changes made in assumptions (on the order of 1‰), can produce substantially lower estimates of the dietary animal protein fraction for given δ¹⁵N values. We consider the implications of various dietary animal protein fractions on agricultural carrying capacities and human population densities in prehistory.     

Modern humans in Sarawak,Malaysian Borneo,during Oxygen Isotope Stage 3: palaeoenvironmental evidence from the Great Cave of Niah

During recent reinvestigations in the Great Cave of Niah in Borneo, the ‘Hell Trench’ sedimentary sequence seen by earlier excavators was re-exposed. Early excavations here yielded the earliest anatomically-modern human remains in island Southeast Asia. Calibrated radiocarbon dates, pollen, algal microfossils, palynofacies, granulometry and geochemistry of the ‘Hell Trench’ sequence provide information about environmental and vegetational changes, elements of geomorphic history and information about human activity. The ‘Hell’ sediments were laid down episodically in an ephemeral stream or pool. The pollen suggests cyclically changing vegetation with forest habitats alternating with more open environments; indicating that phases with both temperatures and precipitation reduced compared with the present. These events can be correlated with global climate change sequences to produce a provisional dating framework. During some forest phases, high counts of Justicia, a plant which today colonises recently burnt forest areas, point to fire in the landscape. This may be evidence for biomass burning by humans, presumably to maintain forest-edge habitats. There is evidence from palynofacies for fire on the cave floor in the ‘Hell’ area. Since the area sampled is beyond the limit of plant growth, this is evidence for human activity. The first such evidence is during an episode with significant grassland indicators, suggesting that people may have reached the site during a climatic phase characterised by relatively open habitats ∼50 ka. Thereafter, people were able to maintain a relatively consistent presence at Niah. The human use of the ‘Hell’ area seems to have intensified through time, probably because changes in the local hydrological regime made the area dryer and more suitable for human use.

老虎山文化的扩张与对外影响

大约以公元前2200年为界, 老虎山文化可分为前、后两大期.前期稳定发展,对外影响有限;后期向南强烈扩张,其陶双鋬鬲、卜骨和细石器镞更流播至黄河中下游广大地区.老虎山文化后期对外扩张的加强和这一时期气候日渐干冷有关.     

华沙渠道与中美关系解冻:华盛顿决策内幕

在冷战的国际大背景下,尼克松政府对苏实施的“缓和”战略使得华盛顿打出“中国牌”,致力于改善同北京的关系。而1969年3月中苏边界武装冲突则为美提供了一个契机。在寻求同中国对话的渠道上,华盛顿首先想到的是华沙渠道,即第135次和136次中美大使级会谈,并为此做了充分的准备。尽管史实证明:华沙渠道的进展不像华盛顿期望的那样顺利,但基本上完成了预期的任务:表达了改善对华关系的愿望,并阐明了不会同苏联合作主宰东亚事务的立场。在华沙渠道完成了既定任务之后,华盛顿又将同北京的联络转为巴基斯坦渠道。
