Warning research participants and patients about potential risks associated with participation/treatment is a fundamental part of consent. However, such risk warnings might cause negative expectations and subsequent nocebo effects (i.e., negative expectations cause negative outcomes) in participants. Because no existing review documents how past research has quantitatively examined nocebo effects – and negative expectations – arising from consent risk warnings, we conducted a pre-registered scoping review (N = 9). We identified several methodological issues across these studies, which in addition to (...) mixed findings, limit conclusions about whether risk warnings cause nocebo effects. (shrink)

Nous considérons la structure dans son rapport au temps : sous ce rapport, la structure est normative, et l’avenir aide à constituer le présent et le passé. Des exemples sont empruntés à l’embryologie et à la géologie. On explique pourquoi il est difficile de concevoir une structure cosmique spatio-temporelle, et comment le développement récent de la physique nous y aide ; dans cette physique, la notion de structure cosmique a un rôle éminent. Il en résulte que seules sont viables les (...) combinaisons qui sont dans La ligne historique de la nature. (shrink)

The subject is in both cases the voyage of the Argo, and therefore the use of the same words is not likely to be coincidental, even though the words themselves are scarcely uncommon. One would hesitate to deny, however, that such reminiscence might be unconscious; that Lucan had famous tags in his head is suggested by another allusion to famous opening lines.

What are physical quantities, and in particular, what makes them quantitative? This book presents an original answer to this question through the novel position of substantival structuralism, arguing that quantitativeness is an irreducible feature of attributes, and quantitative attributes are best understood as substantival structured spaces.

Limits to Action: The Allocation of Individual Behavior presents the ideas and methods in the study of how individual organisms allocate their limited time and energy and the consequences of such allocation. The book is a survey of individual resource allocation, emphasizing the relationships of the concepts of utility, reinforcement, and Darwinian fitness. The chapters are arranged beginning with plants and general evolutionary considerations, through animal behavior in nature and laboratory, and ending with human behavior in suburb and institution. Topics (...) discussed include operant conditioning; the principle of diminishing returns; and issues in relation to mating strategies. Biologists, sociologists, economists, and psychologists will find the book interesting. (shrink)
