Nanotechnologies are technologies applied to a molecular level, which can be embedded in materials including human cells and atoms of mineral, chemical, or physical substrates. Nanotechnologies have been used in attempts to foster interactions between a multitude of products, production processes, and social actors. Just like bio, info, and cognitive science, nanotechnologies belong to the so-called converging technologies, which are expected to change main societal paths toward a more functional and coarser mesh. However, research, development, and di fusion of converging (...) technologies depends on the adaptability of existing economic structures and on the social acceptance of products and services augmented by nanotechnologies. Because of these characteristics, externalities and the risk of systemic divergences caused by potentially noncontrollable or unwanted interactions between sectors, actors, and environments may arise and disturb the e ficiency of the innovation process. Converging institutions, however, aim to manage these market imperfections and social risks in the long run. (shrink)

Forms and Functions of Exchange in Archaic Societies , Marcel Mauss describes an archaic mode of human relations, the gift, whose analysis allows us to specify the reasons for our daily exchanges. Georg Simmel considers the same demands from the starting-point of Wechselwirkung (effects of reciprocity), which contains the properties of all human relations. Their research is based on the following question: Is society possible? The authors examine this question based on notions of sacrifice, reciprocity, and duration, which allow them (...) to isolate three conditions necessary for the existence of human relations: the personalization of, the commitment to, and the duration of this bond. Although it does not qualify as a response to the question asked above, the human relation appears as the inevitable question of sociological reasoning, able to stimulate and open new research perspectives.
