There is evidence to the effect that exposing children to alcohol consumption in the media increases the chances that they will consume alcohol as minors or as adults, and since alcohol consumption is associated with numerous public health issues, calls for stricter regulation can be heard from many quarters. This article argues that with the available research we cannot conclude that exposure to portrayals of alcohol consumption plays a genuine causal role in bringing about the things with which it is (...) associated, that the strength of the correlation is too weak to justify regulation and that the sorts of things with which it is associated only rarely count as genuine harms from a liberal point of view. This article also argues that even if genuine harms were caused, no justification for regulation would directly follow because alcohol in the media could still be protected by freedom of speech and expression. Yet, the article argues that regulation is defensible if it can be shown that the harmful consequences arise in ways that bypass autonomy, or if it can be shown that the harmful consequences are unacceptable from the point of view of so-called ‘proleptic’ autonomy.

Cluster randomised trials are an increasingly important methodological tool in health research but they present challenges to the informed consent requirement. In the relatively limited literature on the ethics of cluster research there is not much clarity about the reasons for which seeking informed consent in cluster randomised trials may be morally challenging. In this paper, I distinguish between the cases where informed consent in cluster trials may be problematic due to the distinct features of ‘population-based’ interventions, which have not (...) been adequately discussed in the research ethics literature, and the cases where informed consent may be problematic for reasons that investigators also encounter in other research designs. I claim that informed consent requirements in cluster trials should be adjusted to the level of risk involved, arguing for a more comprehensive notion of research risk than that currently found in the research ethics guidelines, and the amount of freedom to be sacrificed in relation to a particular research aim. I conclude that these two factors are the most important to consider when assessing whether a cluster study should proceed when informed consent is infeasible or difficult to obtain. (shrink)
