The medicalization thesis derives from a classic theme in the field of medical sociology. It addresses the broader issue of the power of medicine – as a culture and as a profession – to define and regulate social behavior. This issue was introduced into sociology 50 years ago by Talcott Parsons (1951) who suggested that medicine was a social institution that regulated the kind of deviance for which the individual was not held morally responsible and for which a medical diagnosis could be found. The agent of social control was the medical profession, an institutionalized structure in society that had been given the mandate to restore the health of the sick so that they could resume their expected role obligations. Inherent in this view of medicine was the functionalist perspective on the workings of society: the basic function of medicine was to maintain the established division of labor, a state that guaranteed the optimum working of society. For 20 years, the Parsonian interpretation of how medicine worked – including sick-role theory and the theory of the profession of medicine – dominated the bourgeoning field of medical sociology.

Purpose — Since a couple of years, we are confronted with the phenomenon of information overload. In particular, the web provides a rich source of a variety of information mainly in textual, i.e. unstructured form. Thus, web search faces new challenges that are how to make the user aware of the variety of content available and how to satisfy users best with such manifold content.

Methodology — This variety of content is considered as diversity, i.e. the reflection of a result set's coverage of multiple interpretations of a query. Diversification within web search aims on the one hand at adapting the ranking in a way that the top results are diverse. Increasingly important becomes on the other hand the organization and classification of content within diversification.

Findings — Various approaches to diversification are available or currently focus on research activities. They range from an adapted ranking by means of similarity measures or diversity scores to a comprehensive diversity analysis which determines topics and classifies text according to opinions etc.

Implications — Given the high diversity of web content, approaches for diversification are extremely important. Web search tries to address this problem from different perspectives. For the future, combination with image search result diversification is important. Further, benchmarks and standard data sets for evaluations need to be established to ensure comparability of results from various approaches.

Originality/value — This chapter provides an overview on diversity in web search from two directions: (a) Diversity is introduced with its notions and dimensions. (b) Methods to assess diversity within web search are presented.

In this paper, we consider the analysis of models for univariate and multivariate ordinal outcomes in the context of the latent variable inferential framework of Albert and Chib (1993). We review several alternative modeling and identification schemes and evaluate how each aids or hampers estimation by Markov chain Monte Carlo simulation methods. For each identification scheme we also discuss the question of model comparison by marginal likelihoods and Bayes factors. In addition, we develop a simulation-based framework for analyzing covariate effects that can provide interpretability of the results despite the nonlinearities in the model and the different identification restrictions that can be implemented. The methods are employed to analyze problems in labor economics (educational attainment), political economy (voter opinions), and health economics (consumers’ reliance on alternative sources of medical information).

Given the growth in use of Preimplantation Genetic Diagnosis (PGD) in reproductive medicine, most fertility clinics have developed websites describing the benefits of PGD. This chapter examines the media frames employed on 372 U.S. fertility clinic websites marketing PGD to consumers and how these frames promote biomedicalization.

Evaluation of website discourse was conducted with the use of frame analysis, a research methodology for examining the way media frames bind together claims, judgments, and value statements into a narrative that guides readers’ interpretation of an issue.

Findings show that website discourse frames PGD in terms of the attainment of reproductive normality, the management of reproductive risk, and the achievement of technological progress. These discursive frames contribute to the ongoing biomedicalization of reproduction by re-naturalizing conception as a choice rather than a natural fact, by promoting preoccupation with biomedical risk, and by affirming new forms of technological power and expertise.

Examination reveals the ways in which PGD has developed its own system of representations, notions of exchange, and epistemic forms, and highlights the important ethical issues leveraged on fertility clinic websites marketing PGD.

As one of the first attempts to systematically analyze media frames that depict PGD on fertility clinic websites, this study contributes to medical sociology by advancing theoretical and empirical understanding of the media processes shaping accounts of reproductive technologies. Findings also provide a foundation for further analysis of the social norms and bioethical standards arising from consumer marketing of reproductive technologies.

As sociologists we all try to make a contribution to our field. Having completed our comprehensives and dissertations we have read in depth in several areas, have focused on an area that interests us, and have learned the research process whether it uses quantitative or qualitative methodology. We all make our contributions available to the field, but occasionally one among us makes a startling discovery, has an unusual idea or a way to approach a problem, starts examining a new problem at just the right moment, or has an insight into a specific conceptual problem with unusual alacrity. A few among us combine all that skill and happenstance and lead the way into new sociological insights, new areas of research and provide a notable foundation or advancement to an area of knowledge. Saad Nagi is one of those contributors with vision, insight, and skill to see ahead of his time. This paper attempts to bring together in one place his major contributions to the disability knowledge base in sociology.

The approach used in this paper is an in depth review of all of Nagi’s published works in the area of disability. The published literature is grouped into the five areas in which Nagi made major contributions, including major research of the Social Security Disability Insurance process; development of a framework for the disability process; epidemiological definitions and research; development of a coherent set of disability measures; and an examination of the social problem, policy, and program process as developed and practiced in this country.

Nagi made a large and significant contribution in all the areas listed above and much of the measurement, and process examination is still relevant and useful in current research. His framework is still the basis for the very newest models of disability which dominate disability research today.

Researchers need to go back to find Nagi books and articles written in the 60s, 70s, and 80s to ground their work in the originals rather than to take the interpretations of others on this material. The ICF and the Social Model did not originate in Europe alone, but much of the work began in the states in the early 60s with the work of Nagi, Haber, and others and should not be overlooked or ignored.

With an aim to investigate the recent state of the feminist clinics and their negotiation of medical authority in a time of increased technoscientific biomedicalization, and capitalistic health-care system, I conducted a study of two feminist health centers in the Northeast of the United States in 2001–2002. In this chapter, I discuss how the two centers (a nonprofit collective and a for-profit center with a more hierarchical structure) negotiated medical authority in organizational terms as impacted by the larger context of medicine and its interaction with the state, capitalist health-care system, and antiabortion forces. The chapter concludes with a discussion of demedicalization as a multilevel process and implications for feminist care (service delivery) and U.S. Women's Health Movement.

Bayesian Econometrics is a volume in the series Advances in Econometrics that illustrates the scope and diversity of modern Bayesian econometric applications, reviews some recent advances in Bayesian econometrics, and highlights many of the characteristics of Bayesian inference and computations. This first paper in the volume is the Editors’ introduction in which we summarize the contributions of each of the papers.
