Why Ideology Matters for Learning: A Case of Ideological Convergence in an Engineering Ethics Classroom Discussion on Drone Warfare

The relationship between ideology and learning remains insufficiently theorized and sparsely investigated in the learning sciences. Drawing on Stuart Hall’s theorization of ideology, Judith Butler’s notion of the (un)grievability of lives, and Sara Ahmed’s construct of stickiness, we illustrate how insights from critical social theory are indispensable to understanding processes of learning and how perspectives from the learning sciences can enrich critical social theory. Through the analysis of a classroom discussion on the use of militarized drones in an undergraduate engineering ethics course, we show how ideological convergence among participants constructed locally significant categories of “civilian,” “terrorist,” and (un)grievability, which narrowed the possible trajectories for students’ disciplinary learning in engineering and engineering ethics. Our analysis also shows that fleeting moments of ideological expansion offered opportunities for new learning; however, most of these instances of possibility were not sustained through the classroom discussion. We explicate how ideological convergences and expansions, as interactional achievements, profoundly matter for disciplinary learning and students’ identities. In conclusion, we explore the implications of our findings for broader contexts of learning and for the field of the learning sciences.     

Insulin Resistance in Young Obese Subjects and Its Relation to Smoking (A Pilot Study)

Insulin resistance is a condition in which cells fail to respond to the normal actions of insulin. Dietary fat, obesity and smoking have been attributed to increase insulin resistance. However, the prevalence of insulin resistance in young obese subjects and its relation to smoking is not well established. This study comprising seventy-five healthy young adults was undertaken to find insulin resistance in obese smokers and non smokers both. Present study showed an overall prevalence of raised homeostatic model assessment of insulin resistance in 14.7 % otherwise healthy young subjects (20–30 years age group). Non-smokers did not show any significant correlation between insulin resistance and body mass index at either stage (normal, pre-obese as well as obese). Smokers also did not show any significant difference of insulin resistance in normal and pre-obese stages. However, marked increase in homeostatic model assessment of insulin resistance was observed in obese smokers. Homeostatic model assessment of insulin resistance showed a linear trend in relation to body mass index and its values were found to be higher in smokers. Obesity combined with smoking demonstrated statistically significant increase in homeostatic model assessment of insulin resistance.     

Models of Competence and Teacher Training

The use of competence as a basis for the education and training of teachers has become commonplace. Department for Education (DfE) circulars 9/92 (DfE, June 1992) and 14/93 (DfE, November 1993) have indicated the way forward for competence‐based teacher training. This paper suggests that it is possible to identify three models of competence which seem to dominate research. The first is broadly behaviourist in its approach and depends largely upon the inculcation of domain‐specific behaviours. The second can be termed a process model, which attempts to map out the process of competent action in terms of flexibility. The third may be described as a cognitive model, since it attributes such importance to knowledge and understanding in underpinning competent action. Each of these models is examined in relation to certain key variables: their interpretation of knowledge and understanding, methods of assessment, and forms of training. A final section draws attention to important factors which operate in competent performance and which must be realised in any competency approach to the training and education of teachers.     

A cross-cultural study of values of Germans and Americans

The Rokeach Value Survey was used as the instrument to study the values of German and American university students. The Survey was translated into German by the hack-translation method. It was administered to 199 students in Germany in May, 1982 and to 231 students in the United States in the fall. 1982. The results show the differences as well as the similarities between the two groups in their value orientations. The distinct differences between the two groups are: (1) the Germans are more competence oriented in the means they desire to attain their end-states of existence; however, their end-states of existence are society-oriented and interpersonal. (2) The Americans are morality oriented in the modes of conduct they desire to attain their end-states of existence: their end-slates of existence are more personal or self-centered and intrapersonal than those of the Germans. Thus, the means to the end, as well as the end, differ for both groups.

High pressure research on materials

In this article, different methods for generating and measuring high pressure are described. Empirical equations of state (EOS) are illustrated for some standard materials. P Ch Sahu (left) is at the Materials Science Division of Indira Gandhi Centre for Atomic Research, Kalpakkam. He is a specialist in the field of high pressure science and is presently heading this activity at his institute. His primary research areas are in high pressure phase transitions and in synthesis and study of novel materials under extreme pressure and temperature conditions.
