The Strange Situation procedure was developed by Ainsworth two decades agoas a means of assessing the security of infant-parent attachment. Users of the procedureclaim that it provides a way of determining whether the infant has developed species-appropriate adaptive behavior as a result of rearing in an evolutionary appropriate context, characterized by a sensitively responsive parent. Only when the parent behaves in the sensitive, species-appropriate fashion is the baby said to behave in the adaptive or secure fashion. Furthermore, when infants are (...) observed repeatedly in the Strange Situation,the pattern of behavior is said to be highly similar, and this pattern is said to predict the infants' future behavior in a diverse array of contexts. After an exhaustive review of the literature, it is shown that these popular claims are empirically unsupported in their strong form, and that the interpretations in terms of biological adaptationare misguided. There is little reliable evidence about the specific dimensions of parental behavior that affect Strange Situation behavior, although there does appear to be some relationship between these constructs. Temporal stability in security of attachment ishigh only when there is stability in family and caretaking circumstances. Likewise, patterns of Strange Situation behavior only have substantial predictive validity in similarly stable families. Implications for future research and theorizing — particularly as they relate to the use of evolutionary biology in psychological theory — are discussed. (shrink)

This article seeks to reframe the ethical discussion of genetic enhancement, which is the use of genetic engineering to supply a characteristic that a parent might want in a child that does not involve the treatment or prevention of disease. I consider whether it is likely that enhancement can be successfully prohibited. If genetic enhancement is feasible, it is likely that there will be demand for it because parents compete to produce able children and nations compete to accumulate human capital (...) in skilled workers. If some parents or nations begin using genetic enhancement, this will change these competitions in ways that increase the incentives for others to use it. Therefore, a ban on genetic enhancement would be unstable, because once the ban was breached by defectors the motivation of others to uphold it would weaken, making the ban liable to collapse. The argument provides a new perspective on slippery slopes to dangerous technology. Keywords: genetic enhancement, slippery slope argumentation CiteULike Connotea Del.icio.us What's this? (shrink)

Institutional review boards are almost universally considered to be overworked and understaffed. They also require substantial commitments of time and resources from their members. Although some surveys report average IRB memberships of 15 people or more, federal regulations require only five. We present data on IRB meetings at eight of the top 25 academic medical centers in the United States funded by the National Institutes of Health. These data indicate substantial contributions from primary reviewers and chairs during protocol discussions but (...) little from other members, which implies that it may be possible for smaller IRBs to accomplish the same tasks with no reduction in the quality of review.

Objectives. To document the prevalence of ethical requirements in the instructions for authors of journals that published randomized clinical trials in 2005. Design. Using a validated computerized search strategy for retrieving abstracts of RCTs, we retrieved 13 184 references from 2056 journals. These journals were divided into journals that had published > 30 RCTs in 2005, and those that had published fewer. We included all the former and a random sample of the latter journals in the analysis. Measurements. Coders retrieved (...) the instructions for authors for each journal. The coders identified whether 15 ethical requirements were present in each of the instructions, calculated the age of the journal, and determined where it was published. Results. Only 51% of journals required that authors document review by an ethics committee, only 55% required declaration of conflicts of interest, and only 33% required documentation of informed consent. Overall, 48% of instructions required three or fewer of 15 ethics items. Journals publishing many RCTs each year had more ethical requirements, older journals had more requirements, as did journals published in the US. Journals published in Europe had fewer. However, in multiple regression analyses involving the journal's age, location of publication, and number of RCTs published, only publishing many RCTs was associated with having more ethical requirements. Conclusions. Many journals do not require important elements of research ethics in their instructions for authors. Ethical requirements are less common in the many journals that publish few clinical trials each year, journals that have often been overlooked in prior studies of journal ethics.
