Neutron activation analysis of fine grey pottery from Conimbriga,Santa Olaia and Tavarede,Portugal

The concentrations of two major elements and thirteen trace elements in 73 selected sherds of fine grey ware from the Iron Age and Roman period, excavated at Conimbriga, Santa Olaia and Tavarede, Portugal, were determined by instrumental neutron activation analysis. These concentrations were used to calculate distance matrices which were then subjected to cluster analysis employing SAHN and k-means methods, as well as to principal components analysis, to group the sherds according to the overall similarity of their compositional characteristics. The results showed that equivalent groupings appeared regardless of the taxonomic method used. Two major clusters were recognized corresponding to two different sites, namely Conimbriga and Santa Olaia, suggesting that the ceramics from these sites were made locally. No significant differences in compositional patterns were observed between iron age and roman sherds from Conimbriga.     

Living on the Edge? Transformation of a Marginal Pleistocene Landscape Into a Settlement Area in the Northeastern Part of the Netherlands

ABSTRACT

This paper will examine settlement location during the Iron Age in the northeast part of the Netherlands, an area shaped by Pleistocene geology. In recent years, a number of Late Iron Age/Early Roman settlements situated on the low lying slopes of sand ridges and nearby stream ridges revealed traces of an earlier Iron Age occupation. Palynological data revealed that this part of the landscape was used by humans before it was transformed into an area of settlement. An analysis of excavation data from two key sites at Denekamp-De Borchert and Groningen-Helpermaar, as well as other known sites, lead to the conclusion that the transformation of ‘peripheral landscapes’ into permanent settlement locations was preceded by a phase of arable cultivation which left no trace of permanent habitation. It is also suggested that the impact of human behaviour on the natural landscape in the Early and Middle Iron Age was much bigger than previously anticipated. When excavating this type of settlement areas dating to the Late Iron Age, archaeologists must be aware that only of a small group of archaeological features exist. The proposed model for the choice of settlement location may be more widespread, because of similarities in landscape between the study area presented here and other landscapes in Northwest-Europe (e.g. parts of Germany and Denmark).     

Middle Bronze Age Arsenical Copper Alloys in Southern Portugal

In the Iberian Peninsula, the copper metallurgy from the Chalcolithic to the Middle Bronze Age (MBA) was mostly characterized by low arsenic contents. A collection of 53 MBA artefacts from southern Portugal was analysed by micro‐EDXRF, optical microscopy, SEM–EDS and Vickers to investigate the metal composition and manufacture. No technological distinction was found between artefacts from domestic and funerary contexts, which were radiocarbon‐dated to 2000–1500 cal bc . The arsenic contents of almost 100 MBA artefacts from this region, including the above‐mentioned set, have a Gaussian distribution with a high average (3.9 wt% As). Possible explanations are discussed for this distinctive metallurgy at the south‐western end of the Iberian Peninsula.     

Context and the role of policies to attract foreign R&D in Europe

This paper explores the effectiveness of policies ‘in’ attracting the foreign research and development (R&D) of multinational enterprises (MNEs) to specific countries in Europe. We develop a macroeconomic investigation covering 29 European countries during the period between 1990 and 2012 in order to address: (a) whether the provision of direct financial support for business R&D is effective for the attraction of foreign R&D; (b) whether direct support is more effective than indirect support for this purpose and (c) whether the link between direct financial support for business R&D and the foreign R&D of MNEs is conditioned by the context within which the support is provided. The results of the analysis show that, first, the provision of direct financial support is generally effective for the attraction of foreign R&D by MNEs. Second, direct support for business R&D is more effective for this purpose than indirect support. Third, the provision of direct financial support for business R&D yields greater returns in contexts that are more socio-economically suitable for knowledge-intensive, innovative activity.     

Assessment of open spaces in inland medium-sized cities of eastern Andalusia (Spain) through complementary approaches: spatial-configurational analysis and decision support

The benefits of urban open spaces for improving the quality of life and sustainability in cities are widely recognized. The functions they perform within the framework established by urban planning, as well as their metrics, are now more complex than in the past. It is convenient to develop methodologies for the evaluation of these spaces adapted to the present time to check their level of efficiency, which is useful in urban planning for the establishment of new urban open spaces. The aim of this study is to classify such spaces through a methodology that integrates spatial analysis, configuration analysis, and decision support so as to understand their complexity from a more advanced analytical perspective. In order to do this, a prior exploration of specific literature is carried out, which allows the characterization of the functions of urban open spaces by means of the corresponding analysis variables in a weighted manner. The integrated combination of these advanced tools is a step forward in achieving consistent and detailed results for urban open spaces. They perform their functions best in dense, central, equipped, accessible, connected, and easily walkable urban environments. In addition, future recommendations are provided.     

Collagen deamidation in archaeological bone as an assessment for relative decay rates

Attempts to extend methods for dating archaeological bones beyond that of radiocarbon dating, such as amino acid racemization, have met with limited success owing to the dependence on multiple environmental factors and controls. Despite facing similar challenges, deamidation of glutamine has recently been investigated as a potential indicator of ‘thermal age' in archaeological bones, as well as a measure of their preservation quality. In this study, we undertook a series of simulated diagenetic experiments to understand the various factors affecting deamidation. Further, we analysed bones from different Middle Palaeolithic layers from Grotte Mandrin (France), with the results suggesting potential use of deamidation for relative dating, but only in case of extremely well‐preserved layers. The results also suggested the possible use of attenuated total reflectance‐Fourier transform infrared (ATR‐FTIR) spectroscopy as a screening test for soluble collagen before proteomic analysis.     

How Political Support Influences Red Tape through Developmental Culture

This study examines the interrelationship between external political support, internal organizational factors, and red tape, using a sample of information managers from state health and human service agencies. The study defines a red tape model and tests the model by structural equation modeling method. The study finds that political support has a direct effect on red tape. The higher the political support, the lower the level of red tape. The study also confirms an indirect effect of political support on red tape, mediated by developmental culture. Indirect effect through goal clarity has the correct sign but is not statistically significant. Practical recommendations are made for the political environment to provide the opportunity for managerial reforms that are often advocated.     

Add shamans and stir? A critical review of the shamanism model of forager rock art production

The “shamanism” or “neurpsychological” model proposed by Lewis-Williams and colleagues has had a powerful impact on rock art research, and has significantly added to our knowledge of past foragers lifeways in southern Africa and elsewhere in the world. However, this model is primarily based on the view of shamanism as a universal and unvarying characteristic of foragers over space and time. This paper raises both theoretical and empirical problems with this view. The paper examines the relationship between the specific social roles and practices of shamanism and the overarching cosmological structures on which they are based in both southern Africa and Northern Eurasia. In both cases, the paper argues that many cosmological beliefs are highly persistent and durable, extending into prehistory, while the specific practices and roles of shamans are variable, changing to meet the immediate and local needs of their communities. This suggests that rock art is easier to relate to the overarching cosmological dispositions of the people that produced it and the paper closes by suggesting some theoretical and methodological alternatives recognizing this fact.     

Homemaking and Mature Age Gay Men ‘Down-Under’: Paradox,intimacy, subjectivities,spatialities, and scale

The article investigates homemaking processes of mature age gay men living in a provincial Australian town. All too often the experience of older gay men living in non-metropolitan centres has slipped the attention of scholars. The article draws on interview data collected in Townsville (Queensland, Australia) from ten men over 40 years of age who self-identified as gay. These men were asked to explain why they live in Townsville, their understanding of home, and if they understand Townsville as home. We investigate the spatialised understandings of home articulated by these gay men, focusing on two mutually constituted geographical scales: Townsville-as-home and house-as-home, including the material objects within domestic space. For older gay men to call a provincial town home is an ongoing, complex process of reconciling multiple and contradictory subjectivities across different geographical scales. How older gay men constitute Townsville-as-home provides important insights about both non-heterosexual life in provincial centres and how to conceptualise home—as a paradoxical space, contested site, and as multiscalar.     

山西省稷山县农村公共卫生事业述评(1949～1984年)——以太阳村(公社)为重点考察对象

山西省稷山县太阳村(公社)是集体化时代闻名全国的卫生红旗单位,其公共卫生工作及合作医疗制度建设成绩斐然,具有明显的典型意义和时代特征。不过,这种农村公共卫生事业是建立在计划经济体制和高度集中的政治体制以及较低医疗保障水平基础上的,并与历次政治运动关系密切。改革开放后,经济体制逐渐向市场经济过渡,稷山县公共卫生事业因难以适应新的社会经济体制而最终走向了衰落,但其经验和教训可为今后创新农村公共卫生事业、建立新型合作医疗体系提供有益的借鉴。
