Four decades have passed since Harlan and Stemler (1976) proposed the eastern Sahelian zone as the most likely center of Sorghum bicolor domestication. Recently, new data on seed impressions on Butana Group pottery, from the fourth millennium BC in the southern Atbai region of the far eastern Sahelian Belt in Africa, show evidence for cultivation activities of sorghum displaying some domestication traits. Pennisetum glaucum may have been undergoing domestication shortly thereafter in the western Sahel, as finds of fully domesticated pearl millet are present in southeastern Mali by the second half of the third millennium BC, and present in eastern Sudan by the early second millennium BC. The dispersal of the latter to India took less than 1000 years according to present data. Here, we review the middle Holocene Sudanese archaeological data for the first time, to situate the origins and spread of these two native summer rainfall cereals in what is proposed to be their eastern Sahelian Sudan gateway to the Red Sea and the Indian Ocean trade.  相似文献

This study heeds the call for a ‘truth-telling’ of injustices carried out on Aboriginal communities during the colonial acquisition of Australia as stated in the Uluru Statement from the Heart 2017. Here, we discuss the lives of eight Indigenous people buried in Normanton in north-west Queensland (QLD) who died and had their remains collected in the late 1890s as scientific specimens. The remains were later repatriated to the community before being further exposed by erosion in 2015. With the consent and participation of local traditional owners—the Gkuthaarn and Kukatj people—this assessment utilised bioarchaeological, historical and anthropological methodologies to gain a better understanding of Indigenous life and health on the Australian colonial frontier. Gkuthaarn and Kukatj people were engaged throughout the investigation, and statements throughout this piece made by them illustrate how bioarchaeology can inform on past injustices in Australia’s history, bringing them into the public consciousness and aiding the transition to reconciliation through ‘truth-telling’.  相似文献

Since the devolution of welfare policymaking to the states after the passage of the 1996 Personal Responsibility and Work Opportunity Reconciliation Act, there has been contentious debate about drug testing welfare applicants. Beyond elite rhetoric and debate points about the implications of welfare drug testing, extant research remains limited insofar as providing theoretical understanding about what factors influence state proposal of legislation requiring welfare applicants to submit to drug tests. I develop and test expectations that derive from research on welfare attitudes, social construction theory, and policy design—specifically, hypotheses that the proportion of blacks on state temporary assistance for needy families caseloads, as well as state‐aggregate levels of symbolic racism, significantly influence state proposal of drug testing legislation. My multilevel analysis of every state proposal of welfare drug testing legislation from 2008 to 2014 yields strong evidence in support of these hypotheses and paints a more complete picture of the influence of racial attitudes on state welfare policymaking. Specifically, while much research finds evidence of institutional racial biases in the implementation of welfare policy, the evidence presented herein shows that these biases, as well as public biases, influence policymaking at the proposal stage. Implications of these findings are discussed in light of recent significant electoral gains made by Republicans in state legislatures.  相似文献

In Germany a common narrative of the First World War could never be established. In the post-1918 period, explanations of Germany's defeat were highly contested between the political factions of the Weimar Republic. The subsequent Nazi tyranny, the Second World War and the Holocaust came – and continue – to overshadow any other event in German history. During the Cold War, the First World War was largely a forgotten conflict. In recent years, the federal government has remained hesitant about embracing the centenary, but countless exhibitions, seminars, books and other media productions have brought this aspect of history back to public attention from late 2013, and with it has come a renewed public debate on war guilt.

在德国是不会有共同的一战叙事的。1918年以后,对德国战败的解释成为魏玛共和国不同的政治派别的战场。接下来的纳粹独裁、二战以及大屠杀,则让德国历史上的任何其他事件黯然失色。在冷战期间,一战差不多被遗忘了。近些年联邦政府一直对庆祝百年的事犹犹豫豫。不过2013年底以来,无数的展览、研讨会、图书以及其他媒体产品使得这段历史成为公众关注的对象,关于战争的罪孽问题又起纷争。  相似文献
