Man has recognised an association of light with life and medicine for over 3000 years. Today the major challenges to this topic include the elucidation of photochemical reactions involved in photobiology at the molecular level. This includes the use of a variety of modem probing techniques that directly measures the reactivity of excited states and free radicals involved in biological reactions. This text-book is based on such an approach and has arisen from some of the lectures delivered at the NATO ASI held at Hotel Capo Caccia near the Centre for Advanced Research in Photobiology (CARP) in Sardegia, Italy. The ASI took place from 30 September -13 October 1993 and involved a total membership of 90. The book, like the NATO ASI itself, is divided into four themes starting with fundamental aspects and ending with complex medically related systems. Thus Theme 1 covers aspects of the underlying photophysics and photochemistry with particular emphasis on modem experimental techniques to study molecular mechanisms of biological processes. Theme 2 applies many of these fundamental studies to the chemical reactions of most relevance to photobiology and photomedicine such as photo-addition, -isomerization, -sensitization and -pigmentation. The third and fourth Themes deal with the deleterious and therapeutic aspects of light with particular emphasis on the use of Photo-Dynamic Therapy (PDT) to treat cancer and on viral and micro bioi infections.
How do visitors immersing themselves in material places such as shopping malls or video sites online make sense of the experience, enabling criticizing - or consenting to content? How is this evident in behaviour? Reflecting on accounts by Chinese, Indian, Malay and Indigenous members of Malaysian society, this book addresses these questions from a practices perspective increasingly adopted by scholars in marketing and media studies.
The volume provides an account of practices theory from its origins in critical hermeneutics (such as Heidegger, Gadamer and Ricoeur), as reflecting on the processes of embodied understanding, developing alongside interpretive and reception theory. Part I draws upon authors as diverse as Heidegger and Henry Jenkins, with a practices perspective on media and mall consuming shown as developing from forty years of theorizing about audience activity. An empirical study of Malaysian blogging and branding on YouTube exemplifies this approach. Part II considers Malaysians absorbed in social media sites, as everyday visitors and the subjects of consumer research. The book then returns to the material world, exploring the horizons of understanding from which Malaysians enter their mediated malls, and concludes by positioning media practices theory within a spectrum of philosophical ideas.
Recognizing the current (re)turn in Consumer and Media Studies to employing hermeneutics as an account of our embodied human understanding, this book presents its major philosophical proponents, showing how close attention to their writing can now inform and shape research on ubiquitous screen users. As such, it will be of particular interest to students and scholars of Media Studies, Asian Studies and Marketing Studies.
