Craniometric evidence for South African Later Stone Age herders and hunter–gatherers being a single biological population

Later Stone Age (LSA) hunter–gatherers and herders co-existed in South Africa during the last 2000 years. In spite of being the focus of intensive research over the years, the biological status and origins of the herders are still unclear. Did they represent a genetically distinct immigrant population who remained separate from the indigenous hunter–gatherers, or where they indigenous hunter–gatherers who took up herding after contact with herders, probably in northern Botswana? Here, this issue is investigated using craniometric data collected on a large sample of individually dated human crania from coastal LSA context. Mahalanobis distances (D), calculated from the raw metric data, show that there was a small increase in inter-individual craniofacial variation after the introduction of herding at ca. 2000 BP. Here it is argued that this small increase in variation is neither consistent with a large-scale immigration of genetically distinct herders into South Africa, or the long-term co-existence of two genetically distinct populations. Two alternative explanations fit the data better: (1) herding entered South Africa via the small-scale immigration of genetically distinct herders; and (2) local hunter–gatherer populations adopted herding after coming in contact with herders in northern Botswana. While small-scale immigration would not have had a major influence on the local gene pool, it would have increased variation to some extent as immigrants mixed with local populations. If small-scale external gene flow was not a factor in the introduction of herding, secular issues related to the introduction of herding could explain the increased variation in post-2000 BP populations.     

Strategic Alliances in Action: Toward a Theory of Evolution

The popularity and prevalence of strategic alliances for problem solving has been well documented in research on the corporate sector and public policy. However, there has been limited work to date on building a comprehensive theory about the evolutionary process of alliances. The purpose of this article is to synthesize current research on alliance development in order to develop a model of strategic alliance evolution. The theoretical model is built with ideas from prior research as well as findings from our own recent research on alliances in education. We conducted a national study of strategic alliances in charter schools focused on uncovering the process of evolution—including how alliances are initiated, operated, and evaluated—and the various internal and external factors that influence alliance development and progress. Our findings offer a model of strategic alliance evolution and provide direction for future research.     

南非种族政策取向的重大调整--评沃斯特政府的统治及其政策调整

南非的沃斯特政府在当时的国内外历史背景之下,为应付来自外部和内部的压力、维护白人统治和推进现代化进程,在坚持种族主义统治的前提下,以较为切合实际和讲求灵活性的方式,对南非种族政策的取向作出重大调整,对内着手逐渐放松“次种族隔离”的某些方面;对外则奉行“向外看政策”,其意义不仅旨在暂时缓和种族矛盾和改变南非的孤立地位,而且更重要的是为南非现代化进程中的中心环节———南非民主改革开了先河,作了有意义的尝试,积累了经验和教训,可以说是南非民主改革的组成部分之一。     

Partnership,Master Planning and State Provision: a Case Study of ‘Actually Existing Neoliberalism’ on the Central Coast of New South Wales

Over the past decade neoliberalism has come to represent the dominant policy discourse and ideology in the majority of western economies. Following the attention given to this phenomenon at a global (and national) scale, there has been a recent rise in interest in its regional implementation and expression and in how these are mediated through the embedded institutional associations of context dependent localities. Using Brenner and Theodore's (2002a) notion of ‘actually existing neoliberalisms’, this paper explores the hybrid nature of the residential property market. Using one of Greater Sydney's fastest growing regions as an example, this paper shows how residential developments are hybrid constructions, framed by institutional and policy resonances constituted by both state and market actants. Key factors here are the processes of partnership (a process of joining the market and the state), master planning (a process of recognising and pursuing the goals of both the market and the state) and negotiation and provision of state infrastructure (a process of direct state construction of the market).     

GLASS BY DESIGN? RAW MATERIALS,RECIPES AND COMPOSITIONAL DATA*

Compositional analyses of ancient and historic glasses have often been interpreted in terms of the use of specific raw materials in glass manufacture. However, the known inhomogeneity of many glass‐making raw materials and the insolubilities of some compounds make any explanation of compositional data problematic. This paper looks at three glass‐making alkalis with a view to understanding how the compositions of these raw materials are carried through to the final glass. The chemistry and variability of the raw materials are discussed, as is their contribution to the final glass composition. In addition, the choices and decisions made by glassmakers are acknowledged in the final glass compositions. This combination of factors addresses the complexity of predicting the use of specific raw materials from the finished glass composition.     

A NEW SETTING FOR THE NORTHERN BORDER OF THE VENETI: METALLIC FINDS FROM THE VENETIC SITE OF MONTE CALVARIO,AURONZO DI CADORE*

In 2000 several bronze and lead objects were discovered at the Venetic‐Roman site (200 bc –ad 200) of Monte Calvario di Auronzo, in the Italian eastern Alps. They were mostly finished artefacts plus semi‐worked products. Analysis included SEM–EDS, EMPA, XRPD, TMS and AMS spectrometry. The compositional results of the finished artefacts suggest that the choice of the alloy had been made according to the decorative techniques to be used. A semi‐worked high‐leaded bronze object indicates the existence of a metallurgical production of cast artefacts at the site. TMS analyses of a lead ingot exclude local provenance, proving the existence of important trade routes.     

MEDIEVAL BRICK‐BUILDING IN THE CENTRAL ALPS*

Since Roman times, the Alpine area has been the scene of all movements in brick construction—certainly only in a few places, but always at a high technical and aesthetic level. This is all the more surprising as in the mountain areas sufficient stone material is available in a suitable quality for building. Obviously, brick materials displayed overwhelming advantages. Via the mediation of the Church and the secular managerial class, the latent capacity of brick technology was able to rapidly gain a foothold as ideas began to flow internationally. Every era has discovered particular advantages in the use of brick and has expressed them in its architecture.

Wavelength‐dispersive X‐ray fluorescence analysis of ancient glasses*

The application of X‐ray fluorescence to the study of the composition of ancient glasses has been limited by the large amount of material required for samples. In this paper the setting of a reduced sampling XRF method for the analysis of ancient glasses is described. The method involves the preparation of glass beads by melting the sample with lithium tetraborate flux. By means of reference and synthetic samples, the method allows regression curves to be set, covering broad ranges from ppm to high concentrations. By means of a single program, up to 31 elements of interest in the study of ancient glass are analysed. The reproducibility, sensitivity and reliability of the method are discussed. The results demonstrate that 0.2 g of glass is sufficient to obtain accurate and sensitive analyses for most of the elements of interest.
