Origins of molecular neurobiology:The role of the physicists

The revolution in the foundations of physics at the beginning of the twentieth century suggested to several of its most prominent workers that biology was ripe for something similar. In consequence, a number of physicists moved into biology. They were highly influential in initiating a molecular biology in the 1950s. Two decades later it seemed to several of these migrants, and those they had influenced, that the major problems in molecular biology had been solved, and that it was time to move on to what seemed to them the final problem: the nervous system, consciousness, and the age-old mind-body problem. This paper reviews this "double migration" and shows how the hopes of the first generation of physicist-biologists were both realized and dashed. No new physical principles were discovered at work in the foundations of biology or neuroscience. On the other hand, the mind-set of those trained in physics proved immensely valuable in analyzing fundamental issues in both biology and neuroscience. It has been argued that the outcome of the molecular biology of the 1950s was a change in the concept of the gene from that of "a mysterious entity into that of a real molecular object" (Watson, 1965, p.6); the gates and channels which play such crucial roles in the functioning of nervous systems have been transformed in a similar way. Studies on highly simplified systems have also opened the prospect of finding the neural correlatives of numerous behaviors and neuropathologies. This increasing understanding at the molecular level is invaluable not only in devising rational therapies but also, by defining the material substrate of consciousness, in bringing the mind-body problem into sharper focus.

Diaspora identification and long-distance nationalism among Tamil migrants of diverse state origins in the UK

Accounts of Tamil long-distance nationalism have focused on Sri Lankan Tamil migrants. But the UK is also home to Tamils of non-Sri Lankan state origins. While these migrants may be nominally incorporated into a 'Tamil diaspora', they are seldom present in scholarly accounts. Framed by Werbner's (2002) conception of diasporas as 'aesthetic' and 'moral' communities, this article explores whether engagement with a Tamil diaspora and long-distance nationalism is expressed by Tamil migrants of diverse state origins. While migrants identify with an aesthetic community, 'membership' of the moral community is contested between those who hold direct experience of suffering as central to belonging, and those who imagine the boundaries of belonging more fluidly - based upon primordial understandings of essential ethnicity and a narrative of Tamil 'victimhood' that incorporates experiences of being Tamil in Sri Lanka, India and in other sites, despite obvious differences in these experiences. © 2013 Taylor & Francis.

Identifications with an ‘aesthetic’ and ‘moral’ diaspora amongst Tamils of diverse state origins in Britain

This chapter employs Pnina Werbner's notion of diasporas as moral communities of suffering and co-responsibility, as well as aesthetic communities of shared transnational consumption of culture and performance of ritual, and relates this to the case of Tamil migrants of diverse state origins in Britain. Sri Lankan Tamil migrants I interviewed towards my research imagine membership of a Tamil diaspora as based on personal (or familial) experiences of suffering in the Sri Lankan civil war, which acts both to create bonds with other Sri Lankan Tamils, and to distinguish from Tamils of other state origins (Indian, Singaporean etc.) despite cultural commonalities (Werbner's aesthetic diaspora). Conversely, many of the non-Sri Lankan Tamil migrants I interviewed imagined these boundaries in more flexible terms, and claimed membership of the 'community of suffering' in ways which did not necessitate personal experience, but rather privileged symbolic constructions of the ethnic community, and an interpretation of historical and current events in India, Sri Lanka (and other sites of Tamil population) as components of a single narrative of Tamil victimhood.

The competitive advantage of nations:origins and journey

Purpose – The purpose of this paper is to provide an understanding of the origins and journey of the fundamental ideas underpinning Michael Porter’s The Competitive Advantage of Nations as a means of assessing its influence. Design/methodology/approach – Drawing on a reflection of the book’s text and associated works by Porter, the paper shows how Porter’s thinking evolved from his earlier writings, as well as how his ideas went through further periods of development following the publication of The Competitive Advantage of Nations. Findings – The paper focuses on the emergence of Porter’s cluster theory and his growing acknowledgement of the role of innovation within processes of economic development. It shows how these concepts have provided a foundation for contemporary economic development practices. Also, the paper highlights how the fundamental concepts of Porter’s text have shifted from a unit of analysis focused on nations to one where subnational regions are the primary analytical unit. Originality/value – The paper concludes by suggesting that the nature of Porter’s conceptual insights is likely to ensure the long-term endurance of the fundamental lessons contained within The Competitive Advantage of Nations.
