Cognitive reappraisal is an important emotion regulation strategy that shows considerable developmental change in its use and effectiveness. This paper presents a systematic review of the evidence base regarding the development of cognitive reappraisal from early childhood through adolescence and provides methodological recommendations for future research. We searched Scopus, PsycINFO, and ERIC for empirical papers measuring cognitive reappraisal in normative samples of children and youth between the ages of 3 and 18 years published in peer-reviewed journals through August 9th, 2018. (...) We identified 118 studies that met our inclusion criteria. We first present a quantitative review of the methodologies used to investigate cognitive reappraisal in children and adolescents, with attention to variations in methodologies by the sample age range. We then present a qualitative review of findings with attention to: the age at which children begin to effectively use cognitive reappraisal to regulate their emotions, and developmental changes in cognitive reappraisal from early childhood through adolescence. We consider how methodological differences may contribute to inconsistencies in findings, highlight gaps in the literature that remain to be addressed, and make recommendations for future directions.

Culture-independent high-throughput sequencing has provided unprecedented insights into microbial ecology, particularly for Earth’s most ubiquitous and diverse inhabitants – the viruses. A plethora of methods now exist for amplifying the vanishingly small amounts of nucleic acids in natural viral communities in order to sequence them, and sequencing depth is now so great that viral genomes can be detected and assembled even amid large concentrations of non-viral DNA. Complementing these advances in amplification and sequencing is the ability to physically link fluorescently (...) labeled viruses to their host cells via high-throughput flow sorting. Sequencing of such isolated virus–host pairs facilitates cultivation-independent exploration of the natural host range of viruses. Within the next decade, as these technologies become widespread, we can expect to see a systematic expansion of our knowledge of viruses and their hosts. (shrink)

This paper considers the meaning of the term ‘intrusive research’, as used in the UK Mental Capacity Act 2005, in relation to studies in which an informant is asked to provide information about or on behalf of a person who lacks capacity to consent, and who is not otherwise involved in the study. The MCA defines ‘intrusive research’ as research that would legally require consent if it involved people with capacity. The relevant ethical principles are that consent should be sought (...) from people who would be affected by a piece of research and that this requirement should be implemented proportionately. The critical question, for investigators and research ethics committees, is: would provision of the personal information specified in the research protocol significantly affect a person whose capacity is not impaired? If the answer to this question is ‘no’, then the study falls outside the definition of ‘intrusive research’, and the MCA does not apply. (shrink)
