New excavations at Border Cave use high-resolution techniques, including FT-IR, for sediment samples and thin sections of micromorphology blocks from stratigraphy. These show that sediments have different moisture regimes, both spatially and chronologically. The site preserves desiccated grass bedding in multiple layers and they, along with seeds, rhizomes, and charcoal, provide a profile of palaeo-vegetation through time. A bushveld vegetation community is implied before 100,000 years ago. The density of lithics varies considerably through time, with high frequencies occurring before 100,000 years ago where a putative MSA 1/Pietersburg Industry was recovered. The highest percentage frequencies of blades and blade fragments were found here. In Members 1 BS and 1 WA, called Early Later Stone Age by Beaumont, we recovered large flakes from multifacial cores. Local rhyolite was the most common rock used for making stone tools, but siliceous minerals were popular in the upper members.  相似文献

Mark Lilla's summons to recover Hobbes's "art of intellectual separation" is stillborn. Lilla acknowledges the tendentiousness and theoretical inadequacy of Hobbes's approach, yet he falls back on that very strategy, refusing the real task of reconciling political and religious goods.  相似文献

“原始”、“野性”、“财富”、“神秘”点缀着非洲这片美丽的大陆。定格非洲大陆最南端,大西洋与印度洋的交汇处。这个历史上以常年大风大浪的坏脾气著称的风暴角,便是航海人心怀敬意的坐标——好望角。10米高的海浪在这块岬角附近屡见不鲜,航海船只都对它顶礼膜拜。然而今天,这里早已开发成国家公园,过往的只有游客,再大的浪也是风景.  相似文献

An ecological model is proposed for human responses to climatic seasonality in the later Holocene of the southwestern Cape in South Africa. This is an area where pronounced seasonality produces cyclical effects on plant, animal and human communities. The predictions of this model are that: 1. human foragers would switch from plant carbohydrates to seal fat as a winter energy source; 2. capture and butchery of seals would vary with season and seal age; 3. capture and butchery of ungulates would vary seasonally; and 4. seals would be exploited differently from ungulates throughout the year. The model is tested against faunal data from Smitswinkelbaai Cave.
Résumé On propose un modèle écologique des réactions humaines à la saisonalité climatique pour l'Holocène récent dans le cap sud-ouest, Afrique du Sud. C'est une région où la saisonalité produit des effets cycliques sur les communautés végétale, animale et humaine. Les prédictions de ce modèle sont les suivantes: 1. les cueilleurs humains changeaient des féculents végétaux à la graisse de phoque comme source d'énergie en hiver; 2. la prise et la boucherie de phoques variaient avec les saisons et selon l'âge des phoques; 3. la prise et la boucherie des ongulés variaient de façon saisonnière; et 4. les phoques étaient exploités différemment des ongulés pendant toute l'année. On présente un essai préliminaire du modèle sur les données de la caverne Smitswinkelbaai.

Optically stimulated luminescence (OSL) measurements are reported for single grains of quartz from deposits within Sibudu rock shelter. Such measurements enable rejection of unrepresentative grains and application of the finite mixture and central age models to obtain the most reliable age estimates. Three types of single-grain equivalent dose (De) distributions were observed: one sample represented a single dose population, three samples indicated mixing between Iron Age (IA) and Middle Stone Age (MSA) deposits, and 10 samples (in addition to the three mixed samples) showed scattered distributions. The latter type resulted from differences in the beta dose received by individual grains. For these samples, the beta doses were modelled and adjusted accordingly. Ages for the 14 samples collected from MSA deposits post-dating the Howiesons Poort (HP) resulted in three age clusters, which are stratigraphically consistent with the three informally named cultural phases at Sibudu: namely, the post-HP, late MSA and final MSA. Weighted mean ages of 58.5 ± 1.4 ka, 47.7 ± 1.4 ka and 38.6 ± 1.9 ka were calculated for these phases, respectively. The three phases were separated by two occupational hiatuses with durations of 10.8 ± 1.3 ka and 9.1 ± 3.6 ka. We hypothesise that the punctuated presence of humans at Sibudu was determined by large-scale fluctuations in climate during oxygen isotope stage (OIS) 3, which resulted in alternating wet and dry periods. Phases of occupation correspond to wet periods when fresh water was available in the Tongati River, whereas intervals of site abandonment correspond to dry periods when people were forced to migrate in search of a reliable source of fresh water. Where people migrated to, remains unresolved.  相似文献

This article addresses the question of the new South Africa's relationships with other countries in Africa in the context of the idea of an 'African Renaissance' which has recently gained currency. The authors identify two opposing conceptions of Africa's development, which they call 'globalist' and 'Africanist' respectively, and explore the tensions besetting South Africa's participation in an 'Africanist' project. They discuss the dilemma of South Africa's role on the continent as both an obvious and an impossible candidate for leadership, and argue for an 'Africanist' and post-structuralist approach to the political, economic and cultural development of the African continent.  相似文献

This article provides a detailed ethnographic exploration of a case of land restitution in South Africa. It shows how the development discourse invoked during the process of reclaiming land, rather than being imposed in an entirely top‐down manner, has been the result of negotiations between those claiming and those — in government and NGOs — who have helped them claim. The resulting knowledge about the ownership and appropriate governance of land reveals a complex and often contradictory understanding of concepts like ‘custom’, ‘community’ and ‘power’.  相似文献

Government reforms in South Africa during the 1980s have neither adequately addressed the problem of black political rights nor significantly improved the material well‐being of blacks. Nonetheless reform should not be judged irrelevant Reform divided the ruling National Party, weakened its support base and exposed new contradictions in apartheid policy. It also opened critical space in which black resistance movements could build essential organisational strength. By rejecting reform as cosmetic in the mid‐1980s black resistance organisations lost strategic advantages in their struggle which they have only now recovered. Ironically, the government's rhetoric of reform may well force it to enter into genuine negotiations.  相似文献

Research from the Global North suggests that crime increases during a mining boom but not during mining decline. Our evidence from the South African gold mining town of Matjhabeng (formerly Welkom) shows that crime increases during mining decline and affects women in particular. We use social disruption theory to explain women’s experiences of crime and also their involvement in it. We find that criminal activities harm women in particular, that crime has become entrenched within female-headed households, and that women are conflicted in their roles as parents and become participants in crime and beneficiaries of criminal activities. It is a matter for concern that research generally ignores the sociospatial nature of mine closure and its effects on women.  相似文献
