Standing at the gates of Europe: Human behavior and biogeography in the Southern Carpathians during the Late Pleistocene

This study presents a behavioral analysis of Middle and Upper Paleolithic lithic assemblages from 14 sites located in the southern Carpathian Mountains. Using a whole assemblage behavioral indicator, we show that the hominins that manufactured those stone tools do not appear to have differed in terms of the flexibility of the mobility strategies they employed to exploit their landscapes. Rather than biological change, we argue that large-scale climate changes are likely more important drivers of behavioral changes during the Late Pleistocene of the region, including during the Middle–Upper Paleolithic transition. These results agree well with the results of studies having employed this methodology in other regions, suggesting that this is a generalized feature of the transition across Eurasia. Recasting the transition as a mainly ecological rather than purely biocultural process allows us to generate new perspectives from which to approach the question of behavioral change during the Late Pleistocene, and ultimately suggests that the process referred to as the ‘Middle–Upper Paleolithic transition’ is essentially a brief segment of a much more extensive process driven by prehistoric human–environment interactions that would culminate in the highly logistical mobility strategies documented throughout the continent at the Last Glacial Maximum.     

Playing with Flint: Tracing a Child’s Imitation of Adult Work in a Lithic Assemblage

This paper examines the potential for identifying play and children’s imitation in the archaeological record and reviews cultural constructions of play and cross-cultural behaviour. A case study, using a lithic assemblage from a discrete knapping area for Scandinavian Neolithic axe production in Southern Sweden which identifies a child’s activity area, is discussed. The theoretical and methodological assumptions behind play, imitation and its identification as well as its social implications are also examined.

Upper Paleolithic Net-Hunting, Small Prey Exploitation, and Women's Work Effort: A View from the Ethnographic and Ethnoarchaeological Record of the Congo Basin

Recent interest in Upper Paleolithic small prey acquisition focuses on the significance of fiber-based hunting technologies. Some researchers believe the advent of these technologies and presence of small faunas reflect efficient communal net-hunts driven by women's labor. We evaluate different small prey hunting techniques, using ethnographic data from foragers in the Congo Basin. These and other ethnographic data suggest that net-hunting is a high risk endeavor that often has high opportunity costs. We argue that the high costs associated with net-hunting have profound implications for human technological choice, and we evaluate the circumstances that would favor the use of different small prey hunting technologies in the Upper Paleolithic.     

中国互联网发展的地域结构研究

跨世纪的强军战略——学习江泽民关于科技强军的论述

20世纪 90年代以来 ,江泽民根据国际形势的新变化 ,敏锐洞察科学技术在当代综合国力竞争中的决定性作用 ,科学分析两极格局解体后的新形势 ,指明现代国际间的竞争说到底是综合国力的竞争 ,关键是科学技术的竞争 ;他根据世界军事发展新形势 ,适时提出“两个转变” ,把抢占军事制高点作为我军质量建设的重要战略目标 ;江泽民高度重视国防高科技创新 ,强调要尽快掌握维护国家主权和安全所需要的新的“杀手锏” ;他阐明科技强军关键在人才 ,提出建设一支富有创新能力的高素质人才队伍     

2O世纪3O年代科技兴农试验：定县猪种改良

五四新化运动后,科学主义、科技兴国的思想在中国渐为流传,但如何付诸实践,这是一个尚待探索的问题。20世纪二三十年代,晏阳初先生在定县进行的平民教育运动体现了他利用科学技术改造中国农村的志向、总体构想和实践,真正体现了“五四”之后中国知识分子开始把国外先进的科学技术应用于农村的开拓精神。我们选择了猪种改良这个角度,考察平教会是如何踏踏实实地进行科技下乡、改造农村落后面貌的。我们认为,晏阳初的这一思想和实践具有重要的历史价值。     

陶寺遗址出土泥质陶器的中子活化分析与研究

本文采用中子活化分析技术对陶寺遗址出土的74件泥质陶器样品进行了分析研究,结果显示出土于遗址不同功能区的泥质陶器在原材料的使用或制作工艺上存在差异性,这或许表明了不同阶层的人所使用的泥质陶器也是有差别的,已经有了贫富贵贱之分。
