Technology and ecology, 263-315, Carbondale: Southern Illinois University, 1993.Studies concerned with the development of technologies have lately undergone a great impulse. Many of them have been approached from diverse academic perspectives with long-standing traditions and a great number of them have also benefited from the assumption of new conceptual perspectives. In this respect, history, sociology, and philosophy of technology constitute paradigmatic examples. An analysis of the evolution of these various academic paradigms in recent years is carried out, although succinctly, in the first part of this Working Paper. The second part of the Working Paper deals with the issue of social research on public perception with the particular case of the development of biotechnology. Research on the public perception of technologies is a useful tool of a prospective and pre-formative nature which plays an important role as a via media between descriptive analyses (sociology and economy of technical change) and value-oriented studies (technology assessment and science and technology policy analysis). In recent times, the citizens have registered a growing concern over the regulation, management and elaboration of technological policies. This development demands a comprehensive knowledge of the interaction between society and technology. Studies on public perception are highly important not only for the analysis and interpretation of future scenarios in the development of technologies, but also for the task of identifying the kind of public policies required to avoid unwanted effects and for the orientation of technological advancement towards ends considered as beneficial by society as a whole.Peer reviewed
