This essay argues that the 1940 Selective Service Act introduced new tensions between pacifism and male citizenship in the United States. Even as the draft required tens of millions of American men to answer Uncle Sam's call and promoted a new norm of male military obligation, it also specified the acceptable grounds for conscientious objection and created bureaucratic mechanisms for distinguishing between sincere objectors and ‘slackers’. Using Selective Service and organisational records, letters, diaries, interviews and the media, I suggest that male citizenship has been defined not only by idealised and gendered duties, but also by the difficulties and exceptions involved in their practical realisation.  相似文献

Studies in the development of high‐tech industries have shown low levels of community involvement and environmental mobilization. In contrast to the tenets of social movement theories, it seems that the openness of political systems and the tactics of social movements are not enough to lead to increased grassroots environmental resistance in the context of high‐tech development. This article uses the example of high‐tech electronic development in Hsinchu, Taiwan, to examine why and how grassroots activism has been impeded in the past two decades. The article highlights the industrial characteristics and processes within the information technology sector, and analyses existing obstacles to environmental mobilization in the context of a fast‐growing high‐tech economy. It argues that a unique IT development structure has dramatically changed local social characteristics in a way that constrains grassroots mobilization in public social agendas. It also shows how the influential and rapidly expanding IT sector has come to dominate resource‐use in the area, leaving opposing forces more powerless than ever.  相似文献

The Lawrence Berkeley National Laboratory pottery provenance group developed standards and instrumental neutron activation analysis (INAA) methods that are used at many archaeometry laboratories around the world. The background and development of ‘Standard Pottery’ and of methods for INAA are described. Early pottery provenance studies are described, and other research programmes, involving obsidian and magmatic mixing, the origin of the stone used for the Colossi of Memnon, and the ‘Plate of Brass’, are mentioned. Research work by the Laboratory included the discovery of the world‐wide iridium anomaly and extensive subsequent research on what has come to be known as the ‘Asteroid Impact Theory’. Characteristics of the analytical programme for pottery provenance work, including overall aims, precision and accuracy, intercalibration, and irradiation and measurement protocols, are discussed. New research areas developed in the past 15 years, to broaden the usefulness of chemical compositional data for archaeological investigation, and examples of recent work, are described. This research, which makes use of high‐precision X‐ray fluorescence analysis in addition to INAA measurements on sample splits, includes distinguishing the products of different workshops located at the same production site, studies on the significance of the distribution of silver in archaeological pottery and the use of high‐precision chemical compositional data as an aid for making chronological distinctions.  相似文献

Revision in history is conventionally characterized as a linear sequence of changes over time. Drawing together the contributions of those engaged in historiographical debates that are often associated with the term “revision,” however, we find our attention directed to the spaces rather than the sequences of history. Contributions to historical debates are characterized by the marked use of spatial imagery and spatialized language. These used to suggest both the demarcation of the “space of history” and the erasure of existing historiographies from that space. Bearing these features in mind, the essay argues that traditional, temporally oriented explanations for revision in history, such as Thomas S. Kuhn's Structure of Scientific Revolutions, miss the mark, and that a more promising line of explanation arises from the combined use of Michel Foucault's idea of “heterotopias” and Marc Augé's idea of “non‐places.” Revision in history is to be found where writers use imagery to move readers away from rival historiographies and to control their movement in the space of history toward their desired vision. Revision is thus associated more with control than with liberation.  相似文献

吐蕃的统治带来了敦煌图像史上的巨大变革,正是从这一时期开始,敦煌不再像以往那样一味地追求两京风貌,在艺术上出现了多种异域题材与风格。此时的吐蕃正处于佛教的前弘期,多种佛教信仰流入吐蕃,吐蕃在佛教上呈现多元化的倾向。相应地,吐蕃治下的敦煌佛教也带上了多元化的特征,这一点在密教艺术中有着突出的表现。以往,对吐蕃时期敦煌异域风格的作品往往概称之受印度波罗风格的影响,实际上在此时的敦煌几乎找不到一件纯粹的波罗风格的作品,绘画品往往呈现出多种风格影响的痕迹,特别是在吐蕃统治的后期。  相似文献

琉璃构件是中国古代建筑中不可缺少的建筑材料,具有一定的功能性和艺术性。但因其长期处于露天环境之中,会产生釉面蜕变、开裂、脱落和胎体酥粉等多种病变。为了对琉璃构件的全面保护,对洛阳山陕会馆古建群琉璃构件进行了整体调查,发现部分构件釉面产生了一层亮绿色粉状物质,与青铜器粉状锈颜色非常相似,这是一种极其特殊的病变现象。为此,用偏光显微镜、扫描电镜、电子探针及X射线衍射等分析手段对这种病变产物进行分析研究。结果表明,琉璃“粉状锈”的主要成分为PbSO4。它是大气中SO2与水分和琉璃釉面共同作用的结果。该病变的形成过程为:釉面弱酸水膜的形成,釉中铅离子的溶出和铅的硫酸盐形成三大步骤。研究结果可为琉璃构件的进一步保护研究奠定基础。  相似文献
