Networking in France. Is there a French School of Social Network Analysis?

Social Network Analysis (SNA) is a sociology based on interaction that visualizes and models relations between actors. Whereas interaction is approached by classical scholars, we had to wait until the 1970s and the birth of computer science to see social networks analysis develop. This article investigates the influence of SNA in France from the 1980s and wonder if there is a French school of SNA? To do so, we first resume social networks history and highlight its contribution to sociology. Second, we analyze the trajectory and profile of five “disciplinary entrepreneurs,” whose role in the field is important as they master three necessary languages for SNA: English, Mathematics and Computer Science. Third, in order to put back those individuals in their social structures, we cross SNA with the different French sociological tradition(s) (according to topics and methods). Last, we wonder if the institutionalization process succeeded in the creation of institutions from which a French SNA would be able to expand?     

Risk Perception and Information Processing: The Development and Validation of a Questionnaire to Assess Self‐Reported Information Processing

The role of information processing in understanding people's responses to risk information has recently received substantial attention. One limitation of this research concerns the unavailability of a validated questionnaire of information processing. This article presents two studies in which we describe the development and validation of the Information‐Processing Questionnaire to meet that need. Study 1 describes the development and initial validation of the questionnaire. Participants were randomized to either a systematic processing or a heuristic processing condition after which they completed a manipulation check and the initial 15‐item questionnaire and again two weeks later. The questionnaire was subjected to factor reliability and validity analyses on both measurement times for purposes of cross‐validation of the results. A two‐factor solution was observed representing a systematic processing and a heuristic processing subscale. The resulting scale showed good reliability and validity, with the systematic condition scoring significantly higher on the systematic subscale and the heuristic processing condition significantly higher on the heuristic subscale. Study 2 sought to further validate the questionnaire in a field study. Results of the second study corresponded with those of Study 1 and provided further evidence of the validity of the Information‐Processing Questionnaire. The availability of this information‐processing scale will be a valuable asset for future research and may provide researchers with new research opportunities.     

Strategic monitoring at a chemical company

This article describes the development and introduction of a performance measurement system at the Dutch chemical company DSM. This system aims to measure progress toward strategic objectives and key success factors. As such, it can be regarded as a strategic monitoring device which supplements the customary financial controls. The article outlines the company context, the reasons for developing performance measurement, the development and implementation process and the actual approach adopted and concludes with some practical guidelines based on the experiences gained in this case.     

Assessment of the Effectiveness of Radon Screening Programs in Reducing Lung Cancer Mortality

The present study was aimed at assessing the health consequences of the presence of radon in Quebec homes and the possible impact of various screening programs on lung cancer mortality. Lung cancer risk due to this radioactive gas was estimated according to the cancer risk model developed by the Sixth Committee on Biological Effects of Ionizing Radiations. Objective data on residential radon exposure, population mobility, and tobacco use in the study population were integrated into a Monte‐Carlo‐type model. Participation rates to radon screening programs were estimated from published data. According to the model used, approximately 10% of deaths due to lung cancer are attributable to residential radon exposure on a yearly basis in Quebec. In the long term, the promotion of a universal screening program would prevent less than one death/year on a province‐wide scale (0.8 case; IC 99%: –3.6 to 5.2 cases/year), for an overall reduction of 0.19% in radon‐related mortality. Reductions in mortality due to radon by (1) the implementation of a targeted screening program in the region with the highest concentrations, (2) the promotion of screening on a local basis with financial support, or (3) the realization of systematic investigations in primary and secondary schools would increase to 1%, 14%, and 16.4%, respectively, in the each of the populations targeted by these scenarios. Other than the battle against tobacco use, radon screening in public buildings thus currently appears as the most promising screening policy for reducing radon‐related lung cancer.     

Sexual diversity in Urban Norwegians

The purpose of this study is to describe homosexual and heterosexual experiences in terms of sexual fantasies, sexual attraction, sexual conduct, and falling in love in an urban Norwegian population. In 1997, a randam sample of 5,000 persons (18–49 years) was drawn from the population register in Oslo to participate in a sexual behavior survey. Data collection was carried out by means of postal questionnaires and 45% responded. The results indicated that exclusive homosexuality was rare in the population. One exception was the prevalence of homosexual fantasies in women. Compared to respondents who had had exclusively heterosexual contact, respondents reporting bisexual contacts had a significantly higher number of lifetime sex partners, higher frequency of anal and oral sex and masturbation, and lower age at orgasm and masturbation debut. What significantly separated the groups of exclusive heterosexuals, bisexuals, and exclusive homosexuals were attitudes towards various expressions of sexuality and number of lifetime sex partners.     

From Migrant to Minority: Hmong Refugees and the Social Construction of Identity in the United States*

The social constructionist perspective of ethnicity suggests that international migrants may not consider themselves ethnic minorities even when they objectively hold this status. Interview data from forty Hmong refugee leaders support this thesis. One-third have an entirely migrant orientation, while few have an entirely minority orientation. However, one-third are primarily minority in orientation. The migrant orientation prioritizes the ethnic community and problems related to migration. The minority orientation prioritizes relations with U.S. society and problems caused by U.S. institutions. Consistent with findings of prior research, the minority orientation is most common among leaders who have the greatest potential for successful adaptation. But in contrast to prior research, the findings suggest that ethnic awareness among migrants depends not only on attitudes toward assimilation, but also on whether they attribute inequality to their status as newcomers in a host society or to their status as a minority in a racial and ethnic hierarchy.     

INTERPERSONAL DISCRIMINATION AGAINST HMONG AMERICANS: Parallels and Variation in Microlevel Racial inequality

Different racial and ethnic minorities are commonly compared across various measures of macrolevel inequality but have thus far not been compared with respect to microlevel inequality. Using data from interviews with forty-eight Hmong Americans, this article systematically extends Feagin's (1991) analysis of interpersonal discrimination against African Americans to the experiences of everyday racism among a group of foreignborn Asian Americans. Hmong Americans report all of the forms of interpersonal discrimination that Feagin documents for African Americans, suggesting that minorities face a common inequality structure in public face-to-face encounters. Nativism and limited English proficiency, two factors that Feagin did not identify as affecting African Americans, are also important components of interpersonal discrimination against Hmong Americans. These additional dimensions of interpersonal discrimination against suggest that macrolevel patterns of racial and ethnic inequality can lead to variation in microlevel inequality.     

Dynamic predicting by landmarking as an alternative for multi-state modeling: an application to acute lymphoid leukemia data

This paper considers the problem of obtaining a dynamic prediction for 5-year failure free survival after bone marrow transplantation in ALL patients using data from the EBMT, the European Group for Blood and Marrow Transplantation. The paper compares the new landmark methodology as developed by the first author and the established multi-state modeling as described in a recent Tutorial in Biostatistics in Statistics in Medicine by the second author and colleagues. As expected the two approaches give similar results. The landmark methodology does not need complex modeling and leads to easy prediction rules. On the other hand, it does not give the insight in the biological processes as obtained for the multi-state model.
