A great deal of attention has been devoted to risk research. Sociologists in general have limited themselves to varying recognitions of a society at risk and have traced out the paths to disaster. The detailed research has yet to be undertaken. In Risk, now available in paperback, Niklas Luhmann develops a theoretical program for such research. His premise is that the concept of risk projects essential aspects of our description of the future onto the present. Risk is conceived as the possibility of triggering unexpected, unlikely, and detrimental consequences by means of a decision attributable to a decision maker.

Communicating Social Change describes the social challenges that exist in current globalization politics, and examines the communicative processes, strategies and tactics through which social change interventions are constituted in response to the challenges.

Networks of communication evolve in terms of reflexive exchanges. The codification of these reflections in language, that is, at the social level, can be considered as the operating system of society. Under sociologically specifiable conditions, the discursive reconstructions can be expected to make the systems under reflection increasingly knowledge-intensive. This sociological theory of communication is founded in a tradition that includes Giddens' (1979) structuration theory, Habermas' (1981) theory of communicative action, and Luhmann's (1984) proposal to consider social systems as self-organizing. The study also elaborates on Shannon's (1948) mathematical theory of communication for the formalization and operationalization of the non-linear dynamics. The development of scientific communications can be studied using citation analysis. The exchange media at the interfaces of knowledge production provide us with the evolutionary model of a Triple Helix of university-industry-government relations. The construction of the European Information Society can then be analyzed in terms of interacting networks of communication. The issues of sustainable development and the expectation of social change are discussed in relation to the possibility of a general theory of communication. REVIEW In this book, LoetLeydesdorff sets out to answer the question, "Can society be considered as a self-organizing (autopoietic) system. In the process, Leydesdorff, develops a general sociological theory of communication, as well as a special theory of scientific communication designed to analyze complex systems such as the Euroean Information Society. (from review in JASIST 53[1], 2002, 62-63)

In this highly influential study of art forms as models for a theory of communications, Hugh Dalziel Duncan demonstrates that without understanding of the role of symbols in society, social scientists cannot hope to develop adequate models for social analysis. He reviews critically major contributions to communication theory during the past century: Freud's analysis of dream symbolism, Simmel's concept of sociability, James' insights into religious experience, and Dewey's relating of art to experience.

Social Media and Social Order combines a structural analysis of the global impact of social media as contributing to the production of a datafied social order with a series of actor-focused analyses, each examining how roles structured by social media are performed at various sites: enmeshed in European cities, entangled in contested Middle Eastern borders, and embedded in provincial Indian small-town networks. The final section then arcs back to a focus on the general properties of social media networks revealed through two American cases, emphasizing the human costs for the recipients of abuse (legislators of color) and the political costs of participatory propaganda for a deliberative understanding of democracy. A central theme is how the principle of differential treatment embedded in the datafied social order is becoming increasingly widespread across social fields. The book demonstrates how social media are implicated in reshaping social order in ways which align with this principle, including creating new precarious hierarchies of esteem, reinforcing existing social, class and religious hierarchies, opening political discussion to more participants but at the cost of reinforcing local hierarchies and dominant discourses, underlining gendered constructions of national identity, amplifying the abuse received by women and people of color in leadership positions and enmeshing users in the circulation of propaganda which resonates with their preconceptions, thus deepening societal polarization.
