There exists a longstanding association between youth and revolution, partly due to the assumption that the politics of the former are inherently “prefigurative” in nature. Youth politics can often actually be quite conservative, however, as can be observed in contemporary Nicaragua, where rather than attempting to “change the world” in the way that previous militant youth generations were famously associated with, current Sandinista youth activists engage primarily in forms of neo‐patrimonial clientelism. At the same time, the evolving experience of everyday political action by university educated youth in Uttar Pradesh, India highlights how economic endeavours can, under certain circumstances, become a form of politics, often of a more transformative variety than classic forms of collective mobilization. The comparison of Nicaragua and India thus highlights the critical importance of considering the wider environment within which youth mobilize and take action in order to understand how and why particular political “ontologics” emerge.  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.

The conviction and execution of William Joyce (‘Lord Haw-Haw’) for treason to the British crown remains controversial to the present day. He was not, however, the only wartime traitor in the Joyce family. His first cousin, the Irish-born Sergeant Michael Joyce, RAF, also volunteered his services to the Nazis while a prisoner of war in Germany, and arguably compromised himself even more seriously than his more notorious relative. In contrast to the avidity with which William Joyce was pursued, however, Michael Joyce’s crimes — which came to light as the trial of ‘Lord Haw-Haw’ opened at the Old Bailey — were efficiently concealed by prosecutors. The difference in the treatment of the cases of the two Joyce cousins not only sheds new light on the determination of the British authorities to secure a conviction against ‘Lord Haw-Haw’ at all costs, but also reveals the ambiguity and instability of ‘Britishness’ at a moment when, paradoxically, patriotism and national self-confidence were at their twentieth-century zenith.  相似文献

Behavioral ecology is the study of adaptive behavior in relation to social and environmental circumstances. Analysts working from this perspective hold that the reproductive strategies and decision-making capacities of all living organisms—including humans—are shaped by natural selection. Archaeologists have been using this proposition in the study of past human behavior for more than 30 years. Significant insights on variation in prehistoric human subsistence, life history, social organization, and their respective fossil and archaeological consequences have been among the more important results.  相似文献

From 1967 to 1975 a team of archaeologists excavated the site of Tepe Yahya in southeastern Iran under the direction of C. C. Lamberg-Karlovsky. Although there are two forthcoming “final reports” (Hiebert (in progress), and Magee (in press); see also Lamberg-Karlovsky & Potts, 2001), analysis of the materials continues as opportunities allow. Metal artefacts, most especially those made of copper and its alloys, are found at this site from the late Neolithic through the Iron Age. Archaeometallurgical analysis, radiocarbon chronologies, and archaeological interpretation allow one to state when and how a type of metal or a style of object was invented, its use as a trade item, and its function and value to an ancient community. In the hopes of establishing a framework for future archaeometallurgical studies, most of the metal artefacts from Tepe Yahya, Iran, stored in the Peabody Museum of Harvard University, were analysed for elemental composition to complement stylistic and metallographic data.  相似文献
