Biophysical Double‐lives, 1939–1946. Or: Spaces of Boredom. On ‘Information Discourse’ and (Dis)continuities in the Life Sciences. Arguably, few things have shaped the historiography of the mid‐twentieth century psy‐sciences (and indeed, of the life sciences and science/technology/intellectual life quite generally) more profoundly than the story of cybernetics. This essay aims to undermine this technofuturistic picture of epistemological upheavals, of cyborg regimes of knowing, and of the incipient post‐human, by reinserting back into the story the rather dull and unspectacular lives (and occupations) of the great majority of British, ‘diverted’ biologists during World War II. Instead of Ratio Clubbers or Macy‐Conference frequenters, this essay is concerned with a much larger population of would‐be biologists and their most pedestrian appropriations of, and exposures to, electronics. What I argue is that the prevalence and systematicity of such exposures in the course of the personnel‐hungry radio‐war points to a very different – low‐key – picture of the war/technology‐induced deflections of biological science at mid‐century. As an example of how deeply at odds narrations of cybernetic's ascent tend to sit with developments on ground level, special attention will be devoted to the physiologists‐turned‐radar‐scientists Alan Hodgkin and Andrew Huxley, and their war‐time, or more properly, spare‐time investigations into the biophysics of nerve. The latter – technical, difficult, and utterly unphilosophical – while absent from the cyber‐theme‐focused historiography, provided the basis for the tremendous impact Hodkgin and Huxley would in fact have on the mainstream, disciplinarily conservative physiological sciences; the larger aim however is to weave these far from peculiar biographical trajectories into a somewhat bigger picture of the intersections between radar electronics and biological science: a picture which does not centre on sensational discourses but on mundane electronic practices; and thus, on the generational experience of those who were known at the time as “ex radar folk with biological leanings”.  相似文献

Abstract

“May Fourth” has long been considered a turning point for modern China, resulting in continuous heated discussion on the topic since the 1920s. These discussions not only reexamine culture but also have political intent. Many recent scholars have discussed the “ideologization” of May Fourth from the perspective of “memory politics.” They argue that “May Fourth discourse” was not only used to understand and recapture the past, but also to help one’s own cherished values occupy a core position in modern Chinese history, thus using historical interpretation to create a compass for China’s future that conforms to historical tides. From the four great philosophies of modern China, the Nationalists and Communists have incorporated May Fourth into the “Three People’s Principles” and “New Democracy,” respectively. Liberals held up democracy and science as a need for China’s future, and made efforts to propagate and practice democracy in Hong Kong and Taiwan after 1949. As for New Confucians who had continuously criticized May Fourth for being anti-tradition, they supported traditional values but also believed that democracy and science were a “priority and necessity for China's cultural development,” and hoped to use the spirit behind this ideal. They along with liberals criticized the Nationalist and Communist autocracy for departing from May Fourth ideals, and especially noted how May Fourth created fertile ground for the rise and expansion of the Chinese Communist Party (CCP), “resulting in the growth of the Communist Party,” and the Nationalist government’s move to Taiwan. After 1949, Chiang Kai-shek (蔣介石) and the Guomindang (GMD) Nationalist Party he led primarily assessed the May Fourth Movement by synthesizing the views of the liberals and New Confucians. They highlighted the slogans of saving the nation, ethics, democracy, and science to promote ethical education and “national spirit education” as top-priority cultural policies. The focus of this article is to examine how liberals and New Confucians used the topic of May Fourth to criticize the CCP and GMD in Hong Kong and Taiwanese political commentary magazines during the 1950s (approximately 1949–1960). It also explores how the GMD synthesized liberal and New Confucian views to lay out their own position. This discourse shows how May Fourth had diverse interpretations under the context of conflict between the liberals and the New Confucians as well as Nationalists and Communists. The criticism of the ideologization of May Fourth in recent years is actually an important turning point in the scholarly study of May Fourth.  相似文献

Public policy toward the poor has shifted from an initial optimism during the War on Poverty to an ever‐increasing pessimism. Media discussion of poverty has shifted from arguments that focus on the structural causes of poverty or the social costs of having large numbers of poor to portrayals of the poor as cheaters and chiselers and of welfare programs doing more harm than good. As the frames have shifted, policies have followed. We demonstrate these trends with new indicators of the depth of poverty, the generosity of the government response, and media framing of the poor for the period of 1960–2008. We present a simple statistical model that explains poverty spending by the severity of the problem, gross domestic product, and media coverage. We then create a new measure of the relative generosity of U.S. government policy toward the poor and show that it is highly related to the content of newspaper stories. The portrayal of the poor as either deserving or lazy drives public policy.  相似文献

The haunting picture of a disappearing Aral Sea is just part of an overall environmental crisis in the Aral Sea Basin, where millions of people are dependent on agricultural production around the flows of two main rivers, the Amu Darya and Syr Darya. Forced cotton cultivation in the former Soviet Union, in the context of inefficient agricultural organization and production, caused water mismanagement, salinization, water and soil contamination, erosion and the desiccation of the Aral Sea. In the post-Soviet era of ‘transition’, the governments of the Central Asian states and international donors have tried to mitigate the impact of the crisis and contain its scope. Resource-based tensions in the region reflect national (and sometimes ethnic) interests vested in the crucial agricultural sectors that provide foreign exchange and food. Although the Central Asian governments are gradually formulating regional water, land and salt management strategies, the room for manoeuvre that exists to implement policies which would immediately improve the environment, such as efficient water management and sustainable land use, is not being sufficiently utilized.  相似文献

This paper presents and discusses the Neutron Activation Analysis (NAA) results newly obtained from pumice pieces found decades ago at the Egyptian sites of Maiyana, Sedment, Kahun, and Amarna – now in the collections of the Ashmolean Museum, Oxford, and the Petrie Museum of Egyptian Archaeology, London – which could be successfully related to several volcanic eruptions in the Mediterranean. The work contributes to the constant accumulation of knowledge concerning the first appearance of pumice from the so-called Minoan eruption of the Santorini volcano. In addition, it unexpectedly sheds more light on the long-distance trade of Mediterranean volcanic material in the Bronze Age world by disclosing another connection between Lipari and the Eastern Mediterranean.  相似文献
