试论人类身高的地域差异规律及其成因

人类身高高纬高于低纬,牧区高于农区、沿海高于内地、低海拔高于高海拔、城市高于农村、发达国家高于发展中国家。其主要原因是气温的高低、光照的多少和营养的差异。     

Human corpse manipulation and the body as symbol: A case study from the Eastern Pampa–Patagonia transition (Argentina) during the Final Late Holocene

Human body manipulation and secondary burials are widespread funerary practices in many areas of the world. The archaeology of the Pampas and North-Eastern Patagonia, Argentina, is no exception. In this paper, archaeological case studies from the lower basin of the Colorado River during the Final Late Holocene (ca. 1000–250 years BP) are presented and discussed. Secondary burials were recovered that indicated an intentional manipulation of bodies. Evidences of cut marks and the coloring of bone surfaces were recorded. The bundles were composed of individuals of both sexes and diverse age categories. The Pampean region and North-Eastern Patagonia witnessed significant hunter–gatherer population dynamics during the last 1000 years BP. Climatic, ecologic, demographic, and economic explanations have been proposed as the background to these changes. In this paper, it is argued that accompanying these factors, as part of a broader socio-cultural scenario, were significant social interaction networks and processes of social complementarity between groups. In this context, it is proposed that the complexity observed in relation to the handling of bodies is part of a worldview in which the body was seen as material culture – as a symbol – that played an important role for the community in group identity maintenance in a cultural context undergoing significant organizational changes.     

Trilobite biofacies of the Cambrian-Ordovician boundary interval in northern North America

Regional biofacies analysis has been neglected in biostratigraphic studies of the Cambrian-Ordovician boundary interval. Cluster analysis of relative abundance data of trilobites in thirty-seven large collections from ten localities in North America outlines eleven biofacies in the mid-Trempealeauan to early Tremadocian interval. The biofacies are largely lithofacies-specific and are differentiated at generic and familial levels. The composition of trilobite zonal associations in the boundary interval is controlled principally by the sequence of biofacies. Available trilobite zonal schemes can be used only within single lithofacies. The biofacies patterns and faunal dynamics across the upper boundary of the Ptychaspid Biomere do not support hypotheses requiring catastrophic events. In coherence and geographic distribution, Late Cambrian trilobite biofacies are similar to post-Cambrian benthic biofacies.     

梁启超对洋务派的批判

批判洋务思想和洋务派是梁启超变法思想的重要组成部分之一。梁氏认为 ,洋务派也讲变法 ,也谈西学 ,但成效甚微 ,最根本的原因是其变法不知“本原”;并指出 ,洋务派的病根在于“不以民为重 ,其一切法制皆务压制其民”,从而击中了洋务派的要害 ,从政治上划清了维新派与洋务派的界限     

从秦府集团成员仕进状况看区域文化合流

本文结合南北朝至隋末区域文化合流的背景,考察隋末唐初秦府集团成员的仕进状况,其中包括人才类型、家庭政治背景、个体政治势力来源、进入秦府的渠道、个体政治活动空间,认识了以李世民为核心的秦府政治集团,利用争夺天下之机,逐步拓展政治空间,将各地各类精英人才吸纳到秦府集团里来。在此过程中,李世民集团有意识地编织原北周、北齐、南陈入杨隋政治势力后裔,并用关陇、山东、江左这三大政治文化区域人才所长,将他们化入到同一个文化熔炉里融冶,大大推进了区域文化合流的步伐,在中华民族文化融合史上写下了崭新的篇章。     

Early Aptian (Early Cretaceous) freshwater bivalves from the Australian–Antarctic rift,southeast Victoria

The brissid echinoid Schizobrissus insignis (Duncan &; Sladen, 1883) is described from the Fulra Limestone (late middle Eocene), in Kachchh, India. Formerly assigned to Peripneustes or to Meoma it is shown that the species possesses a complete subanal fasciole throughout ontogeny, a characteristic feature of Schizobrissus. Eocene species of Schizobrissus and Meoma show several morphological similarities, but diverged during the late Paleogene and early Neogene.
