Conclusions The centre-periphery relationship historically structured scientific exchanges between metropolis and province, between the fount of empire and its outposts. But the exchange, if regarded merely as a one-way flow of scientific information, ignores both the politics of knowledge and the nature of its appropriation. Arguably, imperial structures do not entirely determine scientific practices and the exchange of knowledge. Several factors neutralise the over-determining influence of politics—and possibly also the normative values of science—on scientific practice.In examining these four examples of Indian scientists in encounters with their peers at the centre, exceptional scientists are seen in a social context where the epistemology of science supposedly describes its practice. Imperialism imposes practices and patronage, which moderate the exchange of scientific knowledge. But, at Level Two, the politics of knowledge and the patterns of patronage within it mediate exchanges between the centre and the periphery.The first step in reconfiguring exchanges between centre and periphery —in this case, between Europe and India during the period 1850 to 1930— is to recognise the relation between the acquisition of resources and the maintenance of legitimacy and identity.67 Political life is not confined to the core of political institutions.68 Second, in examining science as practised in the colonies, it is necessary to see stages of scientific institutions, whose development structures the exchange.From the encounter of Ramchandra and De Morgan, it is evident that the centre-periphery framework should be separated from the models of transmission embedded within it. The notion of translation helps to suggest that scientists bring personal motives and meanings to each encounter. Ramchandra, for example, sought a novel method of teaching Indians calculus, while De Morgan's interest lay in finding a place for algebra in a liberal education.The hierarchy inherent in the centre-periphery framework compels the conclusion that, at Level Two, the autodidact outside the institutions of science must have his work presented to scientists at the centre by authoritative figures from the centre. This is not mainly a question of imperialism, but rather of patronage. The peripheral scientist could not be granted direct entry into the collegial circle until his efforts at the periphery could be translated into the language and concerns of the central community. Ramanujan's enigmatic formulas were translated into the language of analysis by Hardy, which enabled the creation of a field to which Hardy was committed.Scientists from the periphery who were already part of the circle by virtue of their training, were not necessarily subject to the same degree of attestation as other scientists from the periphery. P.C. Ray, with his DSc from Edinburgh, and his position at Calcutta University, had less difficulty in winning the trust of colleagues at the centre, even when he returned to India. On the contrary, remaining at the periphery, he moved from a context of patronage to a sphere of competition. In addition, Ray's collegiality, even at Level Two, was more comprehensive, and connected him with Level One.Eventually, the professional Indian science graduate found collegiality within the international community of scientists. Saha's self-imposed progressive nationalism constrained his identification with the centre and made him a potential competitor instead. Once having achieved eminence in the world of science, C.V. Raman and Saha shifted their work to journals of physics published in India in order to further the cause of physics research in their own country.69
To go beyond the limitations of the centre-periphery model, it is necessary not merely to examine exchanges between scientists functioning in a shared epistemological universe,70 but also to recognise the part played by institutions, the experience of colonialism, and the forms of patronage characterising both colonialism and science. Put another way, although there is relative epistemological autonomy within the disciplinary research communities of science, the interplay between knowledge and power structures this exchange.The scientific links between colonial India and Britain at the turn of the century were mediated by structures which prefigured change. Does structure determine all? If it does, we are left with an Orientalist reconstruction of the docile native, and a passive cultural medium into which science percolates. But this neglects the role of scientists in creating new structures within which they worked. A middle position—one more sensitive to the exigencies of colonial scientific life—would be one where the participants are seen not as the dupes of structure nor the potentates of action, but as occupying a ground between the two.71 相似文献

Medical and neurological science can greatly enhance the effectiveness of education by their research into the nature of man and the limits of his potential. This paper describes recent advances in the field of split-brain research and summarises the qualities which characterise the two cerebral hemispheres. Traditional patterns of education, the author argues, are inadequate since they concentrate almost exclusively on the left hemisphere (e.g. developing powers of linguistic and numerical reasoning), and neglect the right hemisphere which controls perceptual, sensory, musical and intuitive abilities. He suggests what the formal curriculum, teaching strategies and school experiences might do to accelerate the development of the right hemisphere, stressing that all education should aim at neurological symmetry. 相似文献

Results of an experiment about the influence of network television news coverage of combat in Iraq on viewers indicated that, compared with a control condition which featured news stories about combat operations in Iraq described by news anchors, news reports also featuring footage of combat operations increased viewer involvement levels about the war and reduced viewer support for continued military presence in Iraq. Television news footage of combat operations also reduced viewers' pride in U.S. military presence but did not affect other emotions. However, regardless of how news stories were packaged, women experienced greater emotional response to network news stories about combat operations than men. The results also shed light on the potential of inoculation to deflect such influence. 相似文献

Cognitive load theory (CLT) was used to redesign a Database Systems course for Information Technology students. The redesign was intended to address poor student performance and low satisfaction, and to provide a more relevant foundation in database design and use for subsequent studies and industry. The original course followed the conventional structure for a database course, covering database design first, then database development. Analysis showed the conventional course content was appropriate but the instructional materials used were too complex, especially for novice students. The redesign of instructional materials applied CLT to remove split attention and redundancy effects, to provide suitable worked examples and sub-goals, and included an extensive re-sequencing of content. The approach was primarily directed towards mid- to lower performing students and results showed a significant improvement for this cohort with the exam failure rate reducing by 34% after the redesign on identical final exams. Student satisfaction also increased and feedback from subsequent study was very positive. The application of CLT to the design of instructional materials is discussed for delivery of technical courses. 相似文献

We describe an ongoing collaborative curriculum materials development project between Sweet Briar College and Western Michigan University, with support from the National Science Foundation. We present a collection of modules under development that can be used in existing mathematics and biology courses, and we address a critical national need to introduce students to mathematical methods beyond the interface of biology with calculus. Based on ongoing research, and designed to use the project-based-learning approach, the modules highlight applications of modern discrete mathematics and algebraic statistics to pressing problems in molecular biology. For the majority of projects, calculus is not a required prerequisite and, due to the modest amount of mathematical background needed for some of the modules, the materials can be used for an early introduction to mathematical modeling. At the same time, most modules are connected with topics in linear and abstract algebra, algebraic geometry, and probability, and they can be used as meaningful applied introductions into the relevant advanced-level mathematics courses. Open-source software is used to facilitate the relevant computations. As a detailed example, we outline a module that focuses on Boolean models of the lac operon network. 相似文献
