In this paper, I consider the activities of a group of individuals who tinker with and build radio hardware in an informal setting called 'Geek Group'. They conceive of Geek Group as a radical pedagogical activity, which constitutes an aspect of activism surrounding citizen access to low-power FM radio. They are also concerned with combating the gendered nature of hardware skills, yet in spite of their efforts men tend to have more skill and familiarity with radio hardware than women. Radio tinkering has a long history as a masculine undertaking and a site of masculine identity construction. I argue that this case represents an interplay between geek, activist, and gendered identities, all of which are salient for this group, but which do not occur together without some tension. 相似文献

This essay argues that taking the economy seriously in histories of science could not only extend the range of activities studied but also change--often quite radically--our understanding of well-known cases and instances in twentieth-century science. It shows how scientific intellectuals and historians of science have followed the money as a means of critique of particular forms of science and of particular conceptions of science. It suggests the need to go further, to a much broader implicit definition of what constitutes science--one that implies a criticism of much history of twentieth-century science for defining it implicitly and inappropriately in very restrictive ways. 相似文献

This paper assesses Sarkar's ([2003]) deflationary account ofgenetic information. On Sarkar's account, genes carry informationabout proteins because protein synthesis exemplifies what Sarkarcalls a ‘formal information system’. Furthermore,genes are informationally privileged over non-genetic factorsof development because only genes enter into arbitrary relationsto their products (in virtue of the alleged arbitrariness ofthe genetic code). I argue that the deflationary theory doesnot capture four essential features of the ordinary conceptof genetic information: intentionality, exclusiveness, asymmetry,and causal relevance. It is therefore further removed from whatis customarily meant by genetic information than Sarkar admits.Moreover, I argue that it is questionable whether the accountsucceeds in demonstrating that information is theoreticallyuseful in molecular genetics.

The rodents, especially voles, evolved very rapidly during the Quaternary era. Their remains, particularly the teeth, were fossilised by the thousand in prehistoric deposits. The sites can be dated from the degree of evolution attained by the teeth. Since rodents are closely adapted to their biotopes and live under well defined climatic conditions, they are extremely valuable for reconstructing the landscapes and climates of prehistory. In many cases, a single rodent tooth can be used to assess the age of a human skull or a prehistoric settlement, and throw light on the environment and climate of the time. 相似文献
