Randomization is a puzzle for Bayesians. The intuitive need for randomization is clear, but there is a standard result that Bayesians need not randomize. In this paper we propose a model in which randomization is a strictly optimal procedure. The most important aspect of our model is that there are several parties who make different decisions and observe different data. The result also sheds light on the ethical considerations involving randomization in a clinical trial. 相似文献

A Cross‐National Investigation of the Relationship Between Infant Walking and Language Development 下载免费PDF全文
The acquisition of walking has recently been linked with infant language development (Walle & Campos, 2014). If this relation reflects the consequence of an epigenetic event, then it should be present regardless of when the infant typically begins to walk, the infant's culture, and the infant's native language. This study sought to replicate the previously reported link between walking and language development in American infants and investigate whether this relation exists cross‐nationally in typically developing Chinese infants exposed to Mandarin. Urban Chinese infants not only provide a distinct linguistic and cultural population in which to study this relation but also typically begin walking approximately 6 weeks later than American infants. Our results demonstrated that (1) walking infants in both the American and Chinese samples had greater receptive and productive vocabularies than same‐aged crawling infants, (2) differences between crawling and walking infants were proportionally similar in each sample, and (3) the walking‐language relation was present for both noun and non‐noun vocabularies. These findings provide further support of a relation between infant walking onset and language development, independent of age. Avenues for future research of the processes involved in this relation, as well as additional populations of interest to investigate, are discussed. 相似文献

Traditionnellement, la littérature sur le développement consacrée aux marchés du travail d'Amérique latine s'est concentrée sur le nombre d'emplois et la productivité. Mais, étant donné la persistance d'une forte proportion d'emplois informels ou précaires, pour que l'analyse ait du sens, il faut aussi considérer des implications du statut professionnel sur la qualité de l'emploi. Partant d'observations faites ces dernières décennies, les auteurs concluent que la plupart des aspects de cette qualité – protection sociale comprise – dépendent de la signature d'un contrat écrit. Ce constat les conduit à formuler quelques suggestions pour stabiliser l'emploi formel et assurer un financement suffisant de la protection sociale. 相似文献

It is well established today that emotions are an important part of most societal dynamics. The current article focuses on the role of different collective emotional elements in creating, preserving, and resolving conflicts. The main premise is that collective emotions play a pivotal role in shaping individual and societal responses to conflicting events and in contributing to the evolvement of a social context that maintains the emotional climate and collective emotional orientation that have developed. The first part of the article provides a conceptual framework to discuss the relations between conflict, context, and collective emotions. The second part uses the conceptual framework to discuss the societal implications of the articles presented in this issue. Taken together, the parts create a platform for future research on the role of collective emotions in conflict resolution and the construction of cultures of peace. 相似文献
