Prenatal Antecedents of Newborn Neurological Maturation

Fetal neurobehavioral development was modeled longitudinally using data collected at weekly intervals from 24 to 38 weeks gestation in a sample of 112 healthy pregnancies. Predictive associations between 3 measures of fetal neurobehavioral functioning and their developmental trajectories to neurological maturation in the first weeks after birth were examined. Prenatal measures included fetal heart rate (FHR) variability, fetal movement, and coupling between fetal motor activity and heart rate patterning; neonatal outcomes include a standard neurologic examination ( n  =   97) and brainstem auditory evoked potential (BAEP; n  =   47). Optimality in newborn motor activity and reflexes was predicted by fetal motor activity, FHR variability, and somatic–cardiac coupling predicted BAEP parameters. Maternal pregnancy-specific psychological stress was associated with accelerated neurologic maturation.     

Musical collaboration outside school: Processes of negotiation in band rehearsals

This paper presents a study of a series of band rehearsals run by five young people as they practised for a gig together: preparing new songs as well as developing their existing sets. The analysis specifically explores the ways in which the band members collectively develop and evaluate their musical ‘works in progress’. Their interactions were distinctive: with evidence of emotive, highly critical and sometimes conflictual dynamics in places. Within and through such processes the band members constructed a musical ‘shared knowledge’ which resourced the negotiation of their emergent band identity.     

Using Writing to Structure Agency: An Examination of Engineers' Practice

A longitudinal study of four engineers shows that moving into positions of authority and responsibility allows them to claim agency within the structure of the organization. However, that structure is less stable than it first appears, and they use writing to try to establish it in a way that will allow them to achieve their goals. Agency seems to consist of the conjunction of discursively established positions in the organization and participants' taking organizational intents as their own.
