Estimation of Causal Odds of Concordance using the Aalen Additive Model

A simple summary of a treatment effect is attractive, which is part of the explanation of the success of the Cox model when analysing time‐to‐event data since the relative risk measure is such a convenient summary measure. In practice, however, the Cox model may fail to give a reasonable fit, very often because of time‐changing treatment effect. The Aalen additive hazards model may be a good alternative as time‐changing effects are easily modelled within this model, but results are then evidently more complicated to communicate. In such situations, the odds of concordance measure (OC) is a convenient way of communicating results, and recently Martinussen & Pipper (2012) showed how a variant of the OC measure may be estimated based on the Aalen additive hazards model. In this study, we propose an estimator that should be preferred in observational studies as it always estimates the causal effect on the chosen scale, only assuming that there are no un‐measured confounders. The resulting estimator is shown to be consistent and asymptotically normal, and an estimator of its limiting variance is provided. Two real applications are provided.     

Lying in defence of privacy: anthropological and methodological observations

This article deals with three topics: lying, privacy and anthropological research. Their complex intertwinement is analysed using fieldwork notes and through engagement with relevant literature from various disciplines. Experiences of privacy, among researchers as well as among respondents, is underexposed in the literature on social research methodology. Furthermore, lying is sometimes the only effective way to protect one’s privacy. Starting from a research experience with lying respondents in Ghana, I discuss the various circumstances and reasons that lead to lying in defence of privacy, and in particular, concerns about respect in the context of research. Next, I return to the concept of privacy and explicate cultural variations in the experience of privacy. I then look at the consequences for research ethics. The paradoxical conclusion is that lying, a discredited tool of deception, is often applied in order to uphold a widely accepted basic human necessity of life – privacy. Qualitative social researchers should take these concerns about privacy and respect into account and engage in conversations that do not threaten the security of their interlocutors.     

Health Promotion and Flexibility: Extending and Obscuring Power in Organizations

This paper explores the intersection between pursuits of improving organizational flexibility and pursuits of improving employees' health. It is argued that health promotion programmes have the potential of operating as mechanisms of power, which assist organizations in making up self-governing employees who flexibly adapt their lifestyles to the criteria of health and professional success. The paper shows how the fact that health promotion programmes are handled by 'independent' and legitimate health experts, and are provided to employees in the name of their health and well-being, obscures the forces of power in them, making them seem merely as informed ways of helping employees help themselves towards healthier and more successful lives. The paper concludes that health promotion programmes help to establish a new work ethic that challenges the boundary between work and private life. Furthermore, they make a healthy lifestyle part of the competencies that employees are responsible for developing and nurturing.     

Who Holds the Stakes? A Case Study of Stakeholder Identification at Two Nuclear Weapons Production Sites

Traditional risk assessments, including those involving the United States Department of Energy (USDOE), are often criticized for producing useless or noncredible management responses because they did not meaningfully involve the public. The first step to involve the public is to identify appropriate active participants (stakeholders). This study was done to understand the processes used to identify stakeholders to serve on advisory boards established at the two largest remediation sites in the United States: the Hanford Nuclear Reservation in Washington state and the Savannah River Site in South Carolina. The Hanford stakeholder identification process produced an interest-based board whereas the Savannah River Site strategy produced population-based representation. The basic goals of the stakeholder advisory groups were similar. However, different processes were used to identify the participants for the groups in part because of distinctly different social and cultural conditions in the areas affected by the operations of the two facilities, and in part because of the different level of trust of the USDOE and their contractors at Hanford compared with Savannah River. The discussion analyzes their different needs and potential for successful citizen participation.     

Freedom of choice and diversity of options: Some difficulties

This paper explores the possibility for a (non-preference-based) freedom ranking of opportunity sets that is sensitive to the diversity of the options. It turns out that how distances between sets and alternatives are measured is crucial to the derivation of such a ranking. Several proposals are examined, each of which is shown to lead to impossibility results. Earlier versions of this paper were presented at conferences in Kortrijk, Osnabrück, Oisterwijk, Caen and Pavia. I thank the participants at these conferences for their comments. I would also like to thank Steven Hartkamp, Theo Kuipers, Clemens Puppe and especially Kotaro Suzumura for their helpful comments. Furthermore, I am very grateful to Somdeb Lahiri for pointing out a mistake in a previous version of this paper.
