In the first part of this article, we had introduced the notion of quadratic reciprocity and dwelt briefly on its history, which goes back all the way to the work of Fermat. Then we discussed the Law of Quadratic
Reciprocity (‘QRL’), which Gauss named Theorema Aureum. Following this, we gave a not too well known proof of the QRL, due to G Rousseau. Now we give two more proofs of the QRL,
drawing respectively from ideas in linear algebra and field extensions; they too are not very well known.

In Part I, the nature of scalars and vectors was discussed for the Newtonian world. However, in the relativistic world, physical
quantities follow Lorentz transformations. This change of transformation from Galilean to Lorentz results in interesting distinctions
in their properties: mass and time are no longer scalars, time and space become intertwined, etc. This part discusses the
nature of scalars and vectors in the relativistic world. 相似文献

This article discusses the Priority Education Zones project (ZEP) in Mauritius. The original and innovative dimensions of
the project are described, together with the difficulties encountered during the setting-up of the ZEP schools. The article
covers five main issues: the status of the ZEP project; the minimal conditions for success; the implications concerning the
teachers; the obstacles faced; and the strategy devised to implement the ZEP project, while overcoming the obstacles.

Results of a HyperCard method for assessing the performance of expert and novice high school chemistry students solving stoichiometric chemistry problems (balancing chemical equations) have been reported. The assessment involved the use of a HyperCard instrument (Hyperequation) developed on a Macintosh platform to administer a set of five chemistry problems, register student responses, and collect data related to student performance. The chemistry problems have been previously tested and validated in traditional (pen-paper) assessment settings by other researchers. MANOVA results indicate a significant difference between the performance of expert and novice students solving the five stoichiometric chemistry problems using the Hyperequation. The study shows promise in that a HyperCard assessment method could differentiate between the performance of experts and novices in problem solving. The implication is that HyperCard might be a suitable technology for developing performance assessment methods not only in chemistry but also in other science disciplines. 相似文献

Quality assurance strategies for affiliated institutions of HE: a case study of the affiliates under National University of Bangladesh 总被引:1,自引:0,他引:1

Presently, education is considered as the main weapon for national development. However, this tenet has been challenged by several economists. Their findings give rise to a further question: whilst expansion of education increases globally, what is it exactly that continues to hinder a country’s progression? There is no short answer, but one major area of concern is the quality and relevance of the education available. Research for this paper, the first of its kind in Bangladesh, has been carried out by interviews and observation in the affiliates of the National University of Bangladesh, where 80 % of the students in higher education are the underprivileged. The findings show that the legislators ignore the fact that quality of education in the affiliates is perceived as important. 相似文献

AbstractThis article presents a study that seeks to examine the usage of e-journals by the researchers at Aligarh Muslim University. The survey reveals that all the researchers are aware of e-journals in AMU. From this survey, the investigator has been able to find out that many research scholars are consulting e-journals from their departmental labs and computer centers, not only for research purposes but also to update their own knowledge. However, the study also revealed several problems, including lack of training and slow downloading. The researchers’ feelings about the need for print journals as well as electronic journals are also discussed. 相似文献

This study investigates the decay and half-life of online citations cited in four open access journals published between 2000 and 2009. A total of 1158 online citations cited in 1086 research articles published in two science and social science journals spanning a period of 10 years (2000–2009) were extracted. Study found that 24.58% (267 out of 1086) of articles had online citations and these articles contained a substantially very less number of online citations (2.98%) compared to previous study results. 30.56% (26% in Science and 52.73% in Social Science) of online citations were not accessible and remaining 69.44% of online citations were still accessible. The ‘HTTP 404 error message-page not found’ was the overwhelming message encountered and represented 67.79% of all HTTP message. Domains associated with .ac and .net had higher successful access rates while .org and .com/.co had lowest successful access rates. The half-life of online citations was computed to be approximately 11.5 years and 9.07 years in Science and Social science journal articles respectively. 相似文献

This study provides an overview of the research output of Jawaharlal Nehru University, New Delhi, India, in terms of number of publications contributed by faculty members and researchers. The study analyzes bibliometric indicators of published research of Jawaharlal Nehru University as indexed in the Web of Science. There were 5,007 research publications from Jawaharlal Nehru University in the four decades from 1971–2010 (70s; 80s; 90s; and 2000s). The study noted encouraging trends in collaborative research work with multiple-authored research papers. International collaboration in research was also observed among the faculty members and researchers. English was the predominant language of communication. The social scientists and humanists of Jawaharlal Nehru University publish books which are not indexed in the Web of Science. Similarly, research work published in regional languages or published in national level journals are seldom included in the Web of Science. It suggests that research needs to be done by collecting data from the Indian Citation Index and books published by the researchers in order to get an accurate and consolidated picture of the research output of the university. 相似文献
