The most recent national Census demonstrated that Australian Muslims continue to occupy a socioeconomically disadvantaged position. On key indicators of unemployment rate, income, type of occupation and home ownership, Muslims consistently under-perform the national average. This pattern is evident in the last three Census data (2001, 2006 and 2011). Limited access to resources and a sense of marginalisation challenge full engagement with society and the natural growth of emotional affiliation with Australia. Muslim active citizenship is hampered by socioeconomic barriers. At the same time, an increasingly proactive class of educated Muslim elite has emerged to claim a voice for Muslims in Australia and promote citizenship rights and responsibilities.

最近的全国普查显示,澳大利亚的穆斯林仍处于社会经济的弱势地位。在诸如失业率、收入、就业类型、家居拥有等关键指标看,穆斯林一直位于国家平均水平之下。这一模式在最近三次普查(2001、2006、2011)中非常明显。获得资源渠道的有限以及边缘化感觉阻碍着他们充分参与社会,以及在情感上融入澳大利亚。穆斯林的公民意识受困于社会经济障碍。与此同时,也出现了一班受到良好教育的穆斯林精英,这个积极进取的阶层开始为澳大利亚的穆斯林代言,促进他们的公民权利和义务。  相似文献

This article explores the levels of fragmentation and fracture patterns in archaeofaunal assemblages from the lower basin of the Colorado River (Argentina) following Outram's methodology. Remains of ungulates (guanaco) have suffered, in these assemblages, a high degree of fragmentation probably caused during the processing of the carcasses. The presence of helical debris and shaft fragments indicates that fragmentation would respond to processing tasks for the consumption of marrow and possibly bone grease. The results of the application of this methodology that were obtained from the analysis of three late Holocene sites (La Primavera, Loma Ruiz 1 and El Tigre) are presented. These results provide new evidence not only for patterns of marrow and bone grease consumption but also for dealing with the subsistence model proposed for the study area. In this sense, the intensification processes already proposed during the final late Holocene (1000–250 bp ) are discussed. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

Knee osteoarthritis (OA) is a condition that leads to functional deficits in the afflicted. Quantifying these deficits in a clinical population and relating them to bone changes in the distal femur is crucial to identifying potential impairment in archaeological populations. This study provides a hybrid knee OA grading system linking MRI observations of clinical populations and direct bone observations on skeletal populations. This system is then related to 28 pain, disability, and activity limitation outcome variables provided by the OA Initiative through frequency distributions, probability profiles, and Spearman's rank correlations. The results suggest that while the five outcome variables with the highest probabilities were common to males and females, bone changes in knee OA impact males and females differently.

From AD 1274 Chinese emperor Kublai Khan dispatched fleets of ships in a series of attempts to expand the empire's hegemony and extend his rule into East Asia (Japan) and Southeast Asia (Vietnam, Champa and Java). Archaeological remains associated with the fleets and battles have been found at Takashima Island, Japan and on the B?ch Ð?ng River, Vietnam. This paper develops a thematic approach to these sites within a framework of naval battlefield archaeology. It compares the similarities and differences in environmental conditions and archaeological contexts of the two sites in Japan and Vietnam. It also outlines recent archaeological research conducted between 2008 and 2010 on the physical remains at the B?ch Ð?ng River battlefield site.  相似文献

One of the most interesting sites of the Bronze Age in the central area of the Iberian Peninsula is La Motilla del Azuer (Daimiel, Ciudad Real), dated between 2200 and 1350 bc . The main objective of this study was to investigate interpersonal violence in this site and to report an uncommon case of violent death. No traumatic injury was detected in any child, and men and women significantly differed in the frequency of traumas. More traumatisms were found in men from the earlier stages of occupation, including a young man with at least three blunt force traumas and 26 sharp force traumas. The archaeological findings and trauma patterns in the skeletons of the 65 individuals studied suggest a relatively intense level of exposure to violence for adult men in the earlier stages of occupation of this settlement.

This paper provides an up-to-date history of archaeological computer simulation, starting with the early 1970s simulation models, but paying particular attention to those developed over the past 20–25 years. It revises earlier accounts of archaeological simulation by proposing an alternation between programmatic phases, in which published work tends to be about simulation as a method, and mature phases in which there is greater emphasis on the substantive results of simulation experiments. The paper concludes that the burgeoning interest in computer simulation since circa 2000 is largely characterized by mature application in areas where it fits naturally into existing inferential frameworks (e.g., certain strands of evolutionary archaeology) but that explicitly “sociological” simulation remains a challenge.  相似文献

Following the voyages of Christopher Columbus, John Cabot, Alonso de Ojeda and Amerigo Vespucci in the last decade of the fifteenth century, the New World of the Americas entered the cartographic and moral consciousness of Europe. In the 1500 mappa mundi of Juan de la Cosa, navigator and map-maker, we see Europe as a hybrid moral entity, a transitional blend of the medieval and the modern at the crossroads between two mappings of Europe. This paper argues that the Juan De la Cosa map represents a blurred transition between map-making traditions and a mixed moral rhetoric of European identity. The De la Cosa map operates across two sets of imagined axes: held horizontally, the map is set to a Ptolemaic grid with Europe straddling the Prime Meridian, and yet when held vertically it presents a medieval moral continuum in which the Americas occupy an ascendant position, a verdant new Jerusalem in contrast to the Babylon of the Old World. Europe is both drawn to the centre of a new world order, and also pushed to the moral margins in an echo of the medieval mappa mundi still imperfectly resolved.  相似文献

The seismic response of a continuous 4-span bridge designed according to the current Canadian seismic provisions is investigated using Incremental Dynamic Analysis (IDA). Different earthquake types, including shallow crustal events, interface Cascadia subduction, and deep inslab subduction are considered. The median collapse capacities calculated using different record selection methods including Conditional Mean Spectrum (CMS)-based, Uniform Hazard Spectrum (UHS)-based, and epsilon-based methods are compared. The use of the epsilon-based method generally resulted in the highest collapse capacity predictions, but the CMS-based method was less sensitive to the number of records considered in the IDA.  相似文献
