Doctoral Education,Danger and Risk Management

This paper examines how risk management is reworking the doctoral supervisor/candidate relationship. We argue that a larger and more diverse population of doctoral students means special challenges for universities worldwide in managing doctoral programs to optimise their productivity and minimise the risk of failure, costliness and/or litigation. An effect of this is that professional and personal relationships in universities, as in many other public and private institutions, are being reshaped in order to be more closely aligned with risk minimisation policy directives and strategies. To understand what effects such reshaping is having on doctoral education, we bring together anthropological theorising of risk with pedagogical theorising of power and identity in education contexts. This theoretical cross-over between anthropology and education situates the pedagogic work of doctoral training within a culturally constituted order of professional care and risk management. We utilise this framework to interrogate "soft marking" as a specific domain in which risk minimisation is producing new relational identities for both supervisors and students involved in doctoral studies programs.     

The Indian University Grants Commission

The Indian University Grants Commission (UGC), established shortly after Independence, has vested in its powers the responsibility of regulating academic standards as well as disbursing funds provided by central government.Unfortunately, in spite of such responsibilities being entrenched by statute, the UGC has chosen not to exercise them which has had serious consequences for academic standards in Indian universities. The Indian university structure was modelled on the collegiate structure of the University of London with the result that the vast expansion of student numbers in the 1950s and 1960s led to an uncontrolled increase in the number and size of the colleges which themselves came to dominate the university system. Again the UGC chose not to intervene and did not attempt to co-ordinate the growth of the colleges. Bearing in mind the public pressures for an expansion of university education, it would have been unrealistic to expect the UGC to have tried to prevent expansion but it could have sought to moderate it and to impose co-ordination. One result has been the growth of research institutes and high calibre teaching institutes outside the established university system. The UGC is now attempting to remedy the situation but it is clear that this will be a long and uphill task.     

Institutional Discourse and Practice. A Case Study of the Social Construction of Technological Competence in the Primary Classroom

In this paper concepts from Bernstein's theory of pedagogic discourse are used to analyse student communication in the computer setting of the classroom. The perceptions of the classroom teacher and year fwe students, four girls and seven boys, about social relations in the classroom are the focus of analysis. It is argued that the pedagogic device of technocratic masculinity is socially constructed to relay power/knowledge relations. In the case study a group of male students manage to gain a position of power because they select, sequence, organise and transmit technological knowledge forms. The boys’ control over power/knowledge relations in the computer setting is strengthened by the support of the classroom teacher, who acknowledges the boys’ claim to computer expertise. Through the dual actions of a group of boys and the classroom teacher, a fiction about computer knowledge and competency is socially constructed in the classroom. Within the fiction of the technological patriarchy regulating classroom practice, the behaviour of boys is interpreted as ‘risk‐taking’ ‘experimental’ and ‘technologically competent’. Girls are positioned as inactive, passive and rule‐followers within the regulative discourse. While some girls position themselves within the structures of technocratic discourse, other girls deconstruct the ‘truth’ of their computer incompetence and passivity. For the girls, movement across and within the symbolic categories of regulative discourses is a constant struggle of the inner and outer voice. The girls must mediate their social relations with significant ‘others’. In addition, the girls must reconcile their inner voices. They must struggle to negotiate a positioning for themselves as ‘nice’ and ‘good’, carriers of messages, the domestic, the subservient. At the same time, these girls, the daughters of professional career mothers, must struggle to be ‘not nice’, to be powerful, active and gain credit for their computing skills.     

Antidyslipidemic and antioxidant activities of different fractions of<Emphasis Type="Italic">Terminalia arjuna</Emphasis> stem bark

Terminalia arjuna (T. arjuna) stem bark was successively extracted with petroleum ether (A), solvent ether (B), ethanol (C) and water (D). The lipid lowering activity of these four fractions A, B, C, and D was evaluatedin vivo in two models viz., triton WR-1339 induced hyperlipemia in rats as well as fructose rich high fat diet (HFD) fed diabetic- dyslipidemic hamsters. Hyperlipidemia induced by triton caused marked increase in the plasma levels of total cholesterol (Tc), triglyceride (Tg) and phospholipids (PL) in rats. After treament withT. arjuna fractions A, B, C, and D at the doses of 250 mg/kg per oral (p.o.),only the ethanolic fraction (C) exerted significant lipid lowering effect as assessed by reversal of plasma levels of Tc, Tg and PL in hyperlipidemic rats. In another experiment, feeding with HFD produced marked dyslipidemia as observed by increased levels of plasma Tc, Tg, glucose (Glu), glycerol (Gly) and free fatty acids (FFA) in hamsters. After treatment withT. arjuna fractions at the doses of 250 mg/kg p.o. only two fraction (B and C) could exert significant lowering in the plasma levels of lipids and Glu. in dyslipidemic hamsters.In vitro experimentT. arjuna fractions at tested concentrations (50–500 μg/ml) inhibited the oxidative degradation of lipids in human low density lipoprotein and rat liver microsomes induced by metal ions. These fractions when tested against generation of oxygen free radicals at the concentrations (50–500 μg/ml), counteracted the formation of superoxide anions (O⁻²) and hydrodyl radicals (OH) in non enzymic test systems. The efficacy ofT. arjuna fractions as antidyslipidemic and antioxidant agents was found, fraction C> fraction B> fraction A.     

Change levers for unifying top-down and bottom-up approaches to the adoption and diffusion of e-learning in higher education

Using Giddens’ theory of structuration as a theoretical framework, this paper outlines how five prominent United Kingdom universities aimed to integrate top-down and bottom-up approaches to the adoption and diffusion of e-learning. The aim of this paper is to examine the major challenges that arise from the convergence of bottom-up perspectives and top-down strategies. Giddens’ theory is used to understand the dynamics of organisational change as they pertain to the adoption and diffusion of e-learning. This is intended to support our understanding of the interplay between top-down strategy and bottom-up adoption of e-learning. From the research and from our findings, we present a set of change levers that are intended to provide practical value for managers responsible for the diffusion of e-learning strategy in higher education.

Studies on the effect of monosodium glutamate (MSG) administration on the activity of xanthine oxidase, superoxide dismutase and catalase in hepatic tissue of adult male mice

Subcutaneous administration of monosodium glutamate (MSG), to normal adult male mice, for six consecutive days at dose levels of 4 and 8 mg/g body weight, significantly increased the level of free radical initiating enzyme, xanthine oxidase, whereas the activity of free radical scavenging enzymes, like catalase and superoxide dismutase was significantly decreased in hepatic tissue. These observations suggested that ingestion of MSG at dose level of 4 mg/g body weight and above, induced oxidative stress in the hepatic tissue of adult male mice.     

Effect of simultaneous sodium oxalate and methionine feeding with and without Varuna (Crataeva nurvala hook & Frost) therapy on urolithogenesis in guinea pigs

The effect of sodium oxalate and methionine supplementation on stone-related constituents of urine was studied in 18 adult male guinea pigs. Their serum and tissue chemistry and histological changes in urinary tract and liver were also studied. The calciuretic effect of methionine was blocked by oxalate. The decrease in uric acid and citric acid, caused by oxalate, was offset by methionine. Oxalate-induced crystalluria and calcium and oxalate deposition in kidney tissue were lessened by methionine. Administration of Varuna, an indigenuous drug, to oxalate and methionine-supplemented animals prevented either totally or partially most of the urolithogenic effects of oxalate and methionine.
