The role of parental influences in the development of musical performance
Interviews were conducted with 257 children and their parents; all of the children had studied a musical instrument but differed in the extent of their mastery. The purpose of the study was to investigate the role of parents in the development of musical ability. It was discovered that the most successful children had parents who were the most highly involved in lessons and practice in the earliest stages of learning. These successful music learners often had parents who were involved with music themselves. Parental involvement in music typically took the form of listening to music rather than performing it, and tended to increase over the child's learning period. The children who failed to continue with lessons had parents who were, on average, less interested in music and who did not change their own degree of involvement with music over their child's learning period. Overall, the most musically able children had the highest levels of parental support
Characteristics of music teachers and the progress of young instrumentalists
This study investigated the role of some key characteristics of teachers in the development of musical ability. Interviewing 257 children who differed in the extent of their instrumental mastery, it was discovered that the most successful learners regarded their teachers differently to those children who ceased music tuition. The more successful learners rated their first teacher higher than other learners on personal dimensions such as friendliness, and rated their current teacher higher than other learners on task-oriented professional dimensions such as pushiness. Additionally, the highly successful learners studied, on average, with more teachers than the other learners. These learners also generally received more individual instruction than the children who eventually ceased lessons. These findings confirm the importance of matching teacher characteristics to the changing requirements of learners in enabling the development of high levels of musical expertise

Ovine Fetal Thymus Response to Lipopolysaccharide-Induced Chorioamnionitis and Antenatal Corticosteroids
RATIONALE: Chorioamnionitis is associated with preterm delivery and involution of the fetal thymus. Women at risk of preterm delivery receive antenatal corticosteroids which accelerate fetal lung maturation and improve neonatal outcome. However, the effects of antenatal corticosteroids on the fetal thymus in the settings of chorioamnionitis are largely unknown. We hypothesized that intra-amniotic exposure to lipopolysaccharide (LPS) causes involution of the fetal thymus resulting in persistent effects on thymic structure and cell populations. We also hypothesized that antenatal corticosteroids may modulate the effects of LPS on thymic development. METHODS: Time-mated ewes with singleton fetuses received an intra-amniotic injection of LPS 7 or 14 days before preterm delivery at 120 days gestational age (term = 150 days). LPS and corticosteroid treatment groups received intra-amniotic LPS either preceding or following maternal intra-muscular betamethasone. Gestation matched controls received intra-amniotic and maternal intra-muscular saline. The fetal intra-thoracic thymus was evaluated. RESULTS: Intra-amniotic LPS decreased the cortico-medullary (C/M) ratio of the thymus and increased Toll-like receptor (TLR) 4 mRNA and CD3 expression indicating involution and activation of the fetal thymus. Increased TLR4 and CD3 expression persisted for 14 days but Foxp3 expression decreased suggesting a change in regulatory T-cells. Sonic hedgehog and bone morphogenetic protein 4 mRNA, which are negative regulators of T-cell development, decreased in response to intra-amniotic LPS. Betamethasone treatment before LPS exposure attenuated some of the LPS-induced thymic responses but increased cleaved caspase-3 expression and decreased the C/M ratio. Betamethasone treatment after LPS exposure did not prevent the LPS-induced thymic changes. CONCLUSION: Intra-amniotic exposure to LPS activated the fetal thymus which was accompanied by structural changes. Treatment with antenatal corticosteroids before LPS partially attenuated the LPS-induced effects but increased apoptosis in the fetal thymus. Corticosteroid administration after the inflammatory stimulus did not inhibit the LPS effects on the fetal thymus
