An Early Permian brachiopod–gastropod fauna from the Calytrix Formation,Barbwire Terrace,Canning Basin,Western Australia

Taboada, A.C., Mory, A.J., Shi, G.R., Haig, D.W. & Pinilla, M.K., 12.11.2014. An Early Permian brachiopod–gastropod fauna from the Calytrix Formation, Barbwire Terrace, Canning Basin, Western Australia. Alcheringa 39, xxx–xxx. ISSN 0311-5518

A small brachiopod–gastropod fauna from a core close to the base of the Calytrix Formation within the Grant Group includes the brachiopods Altiplecus decipiens (Hosking), Myodelthyrium dickinsi (Thomas), Brachythyrinella narsarhensis (Reed), Neochonetes (Sommeriella) obrieni Archbold, Tivertonia barbwirensis sp. nov. and the gastropod Peruvispira canningensis sp. nov. The fauna has affinities with that of the late Sakmarian?early Artinskian Nura Nura Member directly overlying the Grant Group in other parts of the basin but, as with all lower Cisuralian (and Pennsylvanian) glacial strata in Western Australia, its precise age remains poorly constrained, especially in terms of correlation to international stages. Although the Calytrix fauna lies within the Pseudoreticulatispora confluens Palynozone, the only real constraint on its age (and that of the associated glacially influenced strata) is from Sakmarian (Sterlitamakian) and stratigraphically younger faunas. A brief review of radiometric ages from correlative strata elsewhere in Gondwana shows that those ages need to be updated. The presence of Asselian strata and the position of the Carboniferous?Permian boundary remain unclear in Western Australia.

A Note on Medieval Peasant Demography

Abstract

The deed and mortgage registries of the late nineteenth and early twentieth centuries provide a revealing glimpse into the property and power relations of a community. Who owned what? Who was in a position to broker land deals or liens against property? Who accumulated land, and from whom did they acquire it? Consequently, property records are essential elements for understanding the spatial and relational aspects of property holding, especially in rural areas where other sources, such as city directories or fire insurance maps, are not available. Drawing upon her research of African American landowners in Georgia, the author discusses the basics of deeds and mortgages. She describes likely findings in land records and defines common terms and practices. She argucs that the practice of identifying the race of a grantor or grantee, using (col) or less frequently C. P. to denote skin color, varied over time and by locality. Reasons for this practice are discussed and some interpretive rules are offered that may help identify the deeds and mortgages of African Americans when skin color is not noted.     

海外温州商人创业模式研究——基于32个样本的观察

本研究在相关文献综述的基础上,从创业学的角度,利用改进的威克姆和克里斯蒂安创业模型,对32个海外温商创业样本进行了分析。结果显示,海外温商创业一般过程的四阶段模型,按创业动机、创业经历、创业资源与温州相关程度、创业组织形式和创业过程等标准,分为十种创业模式。海外温商创业模式的形成机制是比较复杂的,除了温商自身因素之外,还需要考虑国际经济发展的宏观背景以及所在国经济发展水平等。从海外温商创业模式看,温州人的成功在于创业者与创业要素的互动,＂温州模式＂实际上更可以称为＂温州人模式＂。     

从海上交通看中国与百济的关系

2～7世纪的东亚世界,正处于国家整合和社会变革的非常时期。其时位于朝鲜半岛西海岸的国家——百济与中国大陆各朝代的交往最为密切和频繁,成为中国大陆、朝鲜半岛和日本列岛诸国之间沟通联系的重要使者和促进东亚汉字和儒学文化圈形成的重要媒介。透过古代史籍文献中的有关记载和考古的发现研究,以连接中国大陆东部和朝鲜半岛西部的海上交通为切入点,可以从航海史的角度揭示中国与百济之间来往和交流的历史面貌。     

Pre-Columbian human occupation patterns in the eastern plains of the Llanos de Moxos,Bolivian Amazonia

Despite an increasing number of publications regarding the Pre-Columbian earthworks of the Llanos de Moxos, there have been no serious attempts to undertake a systematic survey of the archaeological remains of this lowland region in the Bolivian Amazon. Based on the GIS analysis of data gathered in the field and retrieved from satellite images, we discuss the spatial distribution of the Pre-Columbian settlements in a 4500 Km² area of the Llanos de Moxos to the east of Trinidad, capital of the Beni Department, and their relationship with the geographical settings. Our findings shed new light on the prehistory of the region and bear important implications for our understanding of the impact of Pre-Columbian human occupation.     

A study of parametric versus non-parametric methods for predicting paleohabitat from Southeast Asian Bovid astragali

Studies of the African members of the family Bovidae have demonstrated the feasibility of using linear discriminant analysis to predict paleoenvironment based on measurements from postcranial skeletal elements. The use of discriminant analysis depends upon adherence to certain assumptions about the data set. In certain cases, these assumptions are violated, thus reducing the confidence of the results. The research presented here introduces the use of the non-parametric recursive partitioning method as a test of the linear discriminant method for predicting habitat from a collection of modern Bovid astragali from Southeast Asia. This study also provides a critique of the previous African studies. The results indicate that a combination of the parametric and non-parametric methods provides the highest prediction accuracy for Southeast Asian Bovids, though the independent methods do test favorably; thus providing an additional tool for archaeologists and paleoanthropologists in this region.     

The Neolithic Macro-(R)evolution: Macroevolutionary Theory and the Study of Culture Change

The macroevolutionary approach in archaeology represents the most recent example in a long tradition of applying principles of biological evolution to the study of culture change. Archaeologists working within this paradigm see macroevolutionary theory as an effective response to the shortcomings of neo-Darwinian biological evolution for studying cultural evolution. Rather than operating at the level of individual traits, macroevolutionary archaeologists emphasize the role of hierarchical processes in culture change. While neo-Darwinian archaeologists disavow any element of human intent in culture change, to macroevolutionary archaeologists human agency is a key component of cultural evolution that allows cultures to respond to pressures more quickly and with greater degree of flexibility and directedness than found in biological evolution. Major culture change, when it happens, is likely to be rapid, even revolutionary, with periods of rapid change separated by periods of relative stasis of actively maintained stability. The emergence of Neolithic cultures has long been recognized as one of two periods of major revolutionary culture change in human prehistory. Here I examine the record for the Near East, tracing the empirical record for the origin of agriculture in this region, as well as other demographic, social, and ideological components of Neolithic emergence. While the empirical record from the Near East subscribes in a general way to basic principles of macroevolutionary theory, cultural evolution cannot be understood through appeal to principles of biological evolution alone, whether based in macroevolutionary theory or neo-Darwinianism. Instead, the key role of human agency in culture change distinguishes cultural evolution from biological evolution and requires a more pluralistic and less doctrinaire appeal to multiple models of change based in both the biological and social sciences.
