We measure the bone marrow yields of mountain gazelle (Gazella gazella) carcasses to reconstruct gazelle exploitation strategies during the Epipalaeolithic periods in the southern Levant. We present experimentally derived data on the bone marrow content of seven fresh gazelle carcasses, determine the range of marrow yields among individuals of different sexes and seasons of death, and compare the new data to gazelle skeletal element abundances from five Epipalaeolithic assemblages from Israel. We found extensive variation in marrow fat content among individual gazelles. Animals with the highest marrow yields were killed in the spring while animals killed in the early autumn had lower fat contents. Nevertheless, our results suggest that gazelle marrow provided a reliable, albeit small fat resource for prehistoric foragers in all seasons. Strong relationships between bone fragmentation and marrow content demonstrate that Epipalaeolithic people preferentially processed bones with high marrow yields. 相似文献

Despite representing a very accurate method for assessing spatial distribution, Marcon and Puech's M has been insufficiently exploited so far, most likely because its computation relies on pairing every point of interest (i.e., firms, plants) with every other point within the area under analysis. Such a figure rapidly grows to unmanageable levels when said area is larger than a neighborhood or when every industry is taken into account. Consequently, practical applications of M have been exclusively experimental and circumscribed to very limited areas or to a handful of industries. This seems much regrettable since M provides many advantages compared to conventional measures of spatial distribution and also to alternative distance measures. In this article, we assess the reliability of using small administrative units instead of exact postal addresses for the localization of plants, in order to reduce M's computational burden. Working with a dataset that provides the location, the specific industry and the number of employees for every single plant/establishment in Italy for both manufacturing and services, we can also draw a preliminary but certainly interesting picture of Sardinia's economic geography and its development through the Great Recession toughest years between 2007 and 2012. 相似文献

In almost all living creatures, in Primates as well as in seventeenth–eighteenth century human populations, a high infant mortality is the rule; therefore, the scarcity of children's bones in cemeteries is suspicious from a demographic point of view. Though possible in some cases, sociological causes appear less important than the peculiar behaviour of infants' bones in the tomb. This paper examines the physico-chemical properties of infants' bones and their consequences for the preservation of archaeological samples; it proposes a new way of approaching distributions at death in the past. © 1997 John Wiley & Sons, Ltd 相似文献

As I write this, Little Rock is gearing up for the fiftiethanniversary of the desegregation of Central High School, thatnigh archetypal event which seemed to pitch the forces of progressagainst those of ignorance and Southern intransigence. Preciselybecause it is often viewed in such starkly Manichaean terms,the Central High crisis has become the focal point in yet anotherbattle for memory, with some former students—white students—disparagingthe attention paid to the Little Rock Nine, insisting that they,too, suffered during that tumultuous school year. Further, theonly statewide newspaper in Arkansas is headed up by a formerplayer in the crisis who routinely recasts Governor Orval Faubusas a 相似文献

Since 1999, there has been much debate within the international community on what the future status of the autonomous province of Kosovo should be. However, there seems to have been little consideration as to why the Ottoman vilayet of Kosovo and the other majority Albanian-speaking areas (now parts of Montenegro, western Macedonia and north-western Greece) did not become either independent or part of an independent Albanian state, despite the legacy of these decisions. Focussing on British policy and perceptions, this article explores the role of the great powers in the delimitation of Albanian boundaries, particularly in two boundary commissions in 1913 and 1914: one determining the southern Albanian boundary with Greece and the other concerning the northern and north-eastern boundary with Serbia and Montenegro. The first part of the article considers the influences and interactions of two sets of factors in the boundary deliberations: the declared rationale of creating nation-states in south-eastern Europe based upon ethnographic criteria (linguistic boundaries) and the competing role of geopolitical interests in their decision-making, focussing particularly upon British interests. It illustrates that the decisions made to delimit the newly independent Albanian state primarily reflected the resulting great power conflicts and compensations, rather than the professed ethnographic rationale. The second part of the article explores some of the consequences of the decisions made to delimit Albanian boundaries, especially in ‘ethnic’ or national terms. 相似文献

While in the position of Chief Economist of the World Bank, Joseph Stiglitz produced a string of papers, one of which proposed moving beyond the ‘Washington consensus’ to a ‘new development paradigm’, which he hoped the World Bank would espouse. This article offers a critique of that paper and the premises underlying any attempt to reposition an international banking agency. In particular, it focuses on Stiglitz’s attempt to jettison ‘conditionality’ and his argument that developmental assistance should seek to foster socio‐economic transformation and not be about ‘projects’. It also considers the ramifications of the call to make the World Bank ‘the knowledge bank’. Finally, it highlights what is missing from the proposed paradigm, bearing in mind the World Bank’s new ‘holistic development framework’. 相似文献

Osteoarchaeology and genetics agree that the earliest dog domestications took place during the Upper Palaeolithic. However, they partially disagree about the process of domestication. The former indicated multiple origins, when some of the results of the latter suggested that dogs mainly came from a Chinese centre of domestication. In this study, we describe and discuss new evidence for Late Glacial small dogs in the South-West (Pont d’Ambon and Montespan) and North of France (Le Closeau). Special attention was paid to the possibility of miss-identification between small early dogs and dholes (Cuon alpinus), a middle-sized Canidae, the size of which can be similar to early small dogs. Detailed analyses of the archaeological contexts alongside that of taphonomy, morphoscopy, morphometry and pathology, identified 49 small canid remains from the three sites. They allowed us to exclude the presence of dholes and to conclude that they were all small Upper Paleolithic dogs. These, together with other more sparse discoveries, confirmed the presence of Western European Upper Paleolithic Small (WEUPS) dogs from, at least, the Middle Magdalenian to the end of the Epipaleolithic (i.e. 15,000–11,500 cal BP). As they are contemporaneous with the much larger Russian Upper Paleolithic dogs, they plea for several Euro-Asian origins for Late Palaeolithic dogs. 相似文献

Abstract: A new field of “public geographies” is taking shape ( Fuller 2008 ) in geography's mainstream journals. While much is “traditional”, with intellectuals disseminating academic research via non‐ academic outlets ( Castree 2006 ; Mitchell 2008 ; Oslender 2007 ), less visible is the “organic” work and its “more involved intellectualizing, pursued through working with area‐based or single‐interest groups, in which the process itself may be the outcome” ( Ward 2006 :499; see Fuller and Askins 2010 ). A number of well‐known projects exist where research has been “done not merely for the people we write about but with them” ( Gregory 2005 :188; see also Cahill 2004 ; Johnston and Pratt 2010 ). However, collaborative writing of academic publications which gives research participants authorial credit is unusual ( mrs kinpainsby 2008 ; although see Sangtin Writers and Nagar 2006 ). This paper is about an organic public geographies project called “Making the connection”. It is written by a diverse collection of (non‐)academic participants who contributed to the project before it had started, as it was undertaken, and/or after it had finished. This is a “messy”, process‐oriented text ( Cook et al. 2007 ) working through the threads (partially) connecting the activities of its main collaborators, including a referee who helped get the paper to publication. 相似文献
