Research productivity and academics’ conceptions of research

This paper asks the question: do people with different levels of research productivity and identification as a researcher think of research differently? It discusses a study that differentiated levels of research productivity among English and Australian academics working in research-intensive environments in three broad discipline areas: science, engineering and technology; social science and humanities; and medicine and health sciences. The paper explores the different conceptions of research held by these academics in terms of their levels of research productivity, their levels of research training, whether they considered themselves an active researcher and a member of a research team, and their disciplinary differences

Influences on the formation of academics: the role of the doctorate and structured development opportunities

The paper examines influences of doctoral study and structured early career interventions on academic work. It uses evidence from a survey in six Australian universities (n1158) to explore academics engagement with research and teaching development. It regards universities as social situations that are ambiguous, presenting conflicting opportunities for growth and development and the pursuit of personal objectives. Academics emphases on different aspects of academic work involve complex responses that are subject to many influences. It shows that doctoral work may avoid developing key skills that academics need and that the extent to which doctoral study prepares academics for different aspects of their role is different in different disciplines and institutions. It also shows that the conduct of academics in their major roles is little influenced by the training and development they engage in. The paper discusses the survey findings in terms of what constrains and what enables academics to take up particular development opportunities. It argues that to understand academic practice, analysis of how organisational influences are interpreted is needed

"Bioelectronic super-taster" device based on taste receptor-carbon nanotube hybrid structures

We have developed a method to monitor the activities of human taste receptor protein in lipid membrane using carbon nanotube transistors, enabling a "bioelectronic super-taster (BST)", a taste sensor with human-tongue-like selectivity. In this work, human bitter taste receptor protein expressed in E. coli was immobilized on a single-walled carbon nanotube field effect transistor (swCNT-FET) with the lipid membrane. Then, the protein binding activity was monitored using the underlying swCNT-FET, leading to the operation as a BST device. The fabricated BST device could detect bitter tastants at 100 fM concentrations and distinguish between bitter and non-bitter tastants with similar chemical structures just like a human tongue. Furthermore, this strategy was utilized to differentiate the responses of taster or non-taster types of the bitter taste receptor proteins
