Circadian rhythms

Over the series of articles on circadian rhythms, we saw that living organisms exhibit daily rhythms in multiple behaviours and physiological processes. Although some rhythms may be passive responses to 24 h environmental cycles, many are regulated by endogenous-rhythmgenerating machinery called circadian clocks. We have introduced the concept of circadian clocks, their organization and the underlying molecular mechanisms. In this article, we will dwell upon one of the most fundamental questions pertaining to circadian clocks, ‘Why do we have them?’. The aim of this article is not to provide answers, but to discuss the efforts and strategies used to address this question and critically evaluate explanations proposed till date.     

MBA Students' Preparedness for Enterpreneurial Efforts

This is a survey of MBA students'preparedness for launching new businessinitiatives or other entrepreneurialactivities. It explores the readiness of theMBA students, estimated on dimensionscomprising knowledge, attitude, skills,experience, opportunity and networks. Thevariation of the postgraduate students'perceptions along these six dimensions andcertain demographic factors, including gender,stage of the MBA programme, students' permanentresidence, their funding source, enrolmentstatus, employment status, marital status andyears of work experience, was considered. Multiple regressions then established therelationship between entrepreneurialpreparedness and the six dimensions. Finally,some broad implications for the MBA curriculumare considered.     

Science, science education and their discontents: a response to commentaries on the paper, Portrait of a Science Teacher as a Bricoleur: A case study from India

In this response to commentaries by Ali Sammel, Jhumki Basu and Alberto Rodriguez, I present my perspective on three important issues raised by the commentators. These issues relate to the role of a researcher in her field settings and society, the critique of science and science education as oppressive dominant discourses, and co-opting participants as researchers. I argue that researchers should work actively for progressive change in discursive fields such as educational research, in which they are firmly embedded rather than playing an interventionist role in field settings where their discursive positionality maybe temporary and not that rooted. Regarding the critique of science and science education, my response favors a perspective wherein an understanding of the marginalization and oppression of non-western communities caused by western science and science education is counterbalanced by an appreciation of the ways in which marginalized communities can use science and science education for affecting progressive change. Lastly, I recognize the value of co-opting participants in writing and communication of research.

Cancer on the cross-wires

Normal cells in our body that constitute a cellular society are not selfish and this is evident by the fact that they have evolved a phenomenal pathway whereby they cause their own death under conditions of stress that lie beyond the absorbing capacity of the cell. This phenomenon is known as ‘Apoptosis’ or ‘Programmed Cell Death’. However, cancerous cells, which are indeed selfish and proliferate at the cost of their normal counterparts, evade the apoptotic pathway by hindering the mitochondrial release of the proapoptotic protein cytochrome c (Cyt c). Here, we have proposed a scheme whereby the power of proteasome (an intracellular protein chopper) could be harnessed to remove the obstruction placed by cancer cell to the apoptotic process and thereby pushing the cancerous cells to self-destruction, leading to a possible cure for cancer.     

Existence and uniqueness theorem for flow and heat transfer of a non-Newtonian fluid over a stretching sheet

Analysis is carried out to study the existence, uniqueness and behavior of exact solutions of the fourth order nonlinear coupled ordinary differential equations arising in the flow and heat transfer of a viscoelastic, electrically conducting fluid past a continuously stretching sheet. The ranges of the parametric values are obtained for which the system has a unique pair of solutions, a double pair of solutions and infinitely many solutions.     

Factors contributing to the implementation of inclusive education in Pacific Island countries

This study reports the outcomes of focus group discussions reflected in presentations of concept maps relating to the implementation of inclusive education in the Pacific based on the views of 39 stakeholders from four countries (Fiji, Samoa, Solomon Islands, and Vanuatu). Five themes emerged, with one of the strongest being that of culture, community, and religion. This, amongst other ideas, is central to Pacific Islanders’ understandings of inclusive education implementation, and results in some tensions between western educational ideas and the local context. The implications of this paper clearly show that local culture and context must be accounted for, if inclusive education is to be successfully implemented in the region.     

Chemical oscillations

A chemical reaction is usually thought of as coming together of reactant molecules to form products. The concentrations of initial components (reactants) decrease, and concentrations of products increase until they reach a well defined state: the equilibrium. This process is accompanied by a decrease of the system free energy (compared at constant pressure and temperature), until it reaches a minimum in the equilibrium. Thus, it follows from the nature of the law of mass-action that every simple reaction approaches its equilibrium asymptotically, and the evolution of any physico-chemical system leads invariably to the steady state of maximum disorder in the universe. Normally, chemical systems approach equilibrium in a smooth, frequently exponential relaxation. Under special circumstances, however, coherent behavior such as sustained oscillations are observed and the oscillations of chemical origin have been present as long as life itself. Such reactions can be studied using mathematical models, the Lotka-Volterra model being the earliest and the simplest one.
