Iron Age Saunas of Northern Portugal: State of the Art and Research Perspectives

Special buildings used as saunas have been found in certain large hillforts in the north of Portugal and in the Cantabrian coastal area of Asturias and Galicia in Spain. The principal aim of this study is to highlight the importance of these buildings in the archaeology and art of the European Iron Age, where they are very rarely mentioned. Two approaches are developed: in Parts 1 and 2, we explain the structure of the buildings, their function, and the current debate surrounding their dating. In Parts 3 and 4, further analyses are developed on their position in the landscape, associating the saunas with the public life of the hillforts, and on the decorative structure of the pedras formosas (‘beautiful stones’) found in some of them, and their relation to certain artistic trends in so‐called Celtic art.     

莫高窟第76窟八塔变相关问题再探

莫高窟第76窟内的八塔变图像出现于宋初时期,其粉本应是中印佛教交流过程中由印度僧人传至敦煌的。而这一题材绘入洞窟时正处在敦煌末法思潮盛行的背景之下,作为正法象征的八塔变壁画蕴含了信众渴求佛法不灭的心愿。同时,莫高窟第76窟作为大族营建的家窟,具有举办佛事活动的功能,八塔变与窟内其他题材的相互联系能够更好地服务于信众的信仰实践活动。     

Entrepreneurship dynamics and economic cycles: an analysis for local systems and industrial districts

ABSTRACT

We propose a research framework that expressly takes into account the moderating and differentiated influence that can be exerted on the dynamics of entrepreneurship capital by both the type of local system and the economic situation. Moreover, we investigate whether industrial districts are a more favourable context for the evolution of the entrepreneurship capital. We apply this framework to data of municipalities, grouped in local labour systems, of three Spanish regions and in two sub-periods of, respectively, crisis (2007–2011) and incipient recovery (2011–2014). Results are consistent with a set of sensible relations that can be extracted from the background literature.     

大都市中心区生产性服务业集群的空间溢出——以广州市天河区为例

空间溢出对产业集群形成发展具有重要意义。但空间溢出对生产性服务业集群的影响机制并不清楚。本文基于1 km×1 km网格和2013年广州市中心区--天河区的企业经济普查数据，采用空间数据分析技术，识别生产性服务业集群，分析集群特征，探测集群溢出类型。结果发现：①生产性服务业集群区位指向大城市中心区的核心地域，具有五种集群类型分异，空间呈不完全耦合。②生产性服务业集群空间规模受Jocobs型和MAR型两种溢出调控，在MAR型溢出作用下的集群空间规模相对较小。③信息服务业集群的溢出为负效应说明溢出作为一种潜在利益，在转化为集群优势的过程中存在过滤效应。

Analysis of Neolithic human remains discovered in southern Italy

The authors describe the discovery of the remains of two unidentified skeletonised individuals in a small town located in southern Italy. The bodies were discovered while workers were preparing to lay an oil pipeline. The two individuals were found at a depth of 2 meters, and in very close proximity to one other. The recovery process of the skeletonised remains and their related findings, carried out by a team of forensic anthropologists and archaeologists, is described here.Archaeological examination determined that the remains date back to the 4th millennium B.C. Forensic anthropological and odontological examinations were performed to determine the biological profile of the skeletal remains by estimation of age and height, as well as the determination of sex. Age determination was performed by the Kerley and Ubelaker (1978, Revision in the microscopic method of estimating age at death in human cortical bone. Am. J. Phys. Anthropol., 49, 545–546) histological method using a 1 mm thick piece of bone tissue taken from the diaphyses of femur in both individuals. Dental age was estimated by examining root transparency. In order to determine the height of the individuals, various research methods based on the dimensional values of particular skeletal structures were applied. DNA analysis showed genotype differences of all the systems as compared to the haplotypes of present day subjects. This provided confirmation that the skeletal remains were from individuals of an ancient population (4th millennium B.C.). In addition, radiocarbon dating provided useful information as to the approximate period of death of the individuals. Interpretation was further enhanced by analysis of various bone fragments from each of the skeletons by high resolution mass spectrometry. 3D computerized imaging was used to analyse the patterns of skull fractures present, which resulted in supporting the hypothesis that the fractures were caused by stoning.
