BACKGROUND Recent genetic evidence suggests that the most important environmental influences on normal and pathologic development are those that are not shared by siblings in the same family. We sought to determine the relationship between differences in parenting styles and depressive symptoms and antisocial behavior in adolescence, and to compare the(More)
This study examined 2 samples of adolescents and mothers using a child-based design (Nonshared Environment in Adolescent Development [NEAD] project, N = 395 families) and a parent-based design (Twin Moms [TM] project, N = 236 twin family pairs) to compare genetic and environmental influences on mothering. For both samples, the same measures of positivity,(More)
We have measured the rest-frame B, V, and I-band light curves of a high-redshift type Ia supernova (SN Ia), SN 1999Q (z = 0.46), using HST and ground-based near-infrared detectors. A goal of this study is the measurement of the color excess, E B−I , which is a sensitive indicator of interstellar or intergalactic dust which could affect recent cosmological(More)
In adolescence, antisocial and depressive symptoms are moderately stable and modestly correlated with each other. We examined the genetic and environmental origins of the stability and change of antisocial and depressive symptoms and their co-occurrence cross-sectionally and longitudinally in a national sample of 405 adolescents. Monozygotic (MZ) and(More)
This study employs findings from social comparison research to investigate adolescents' comparisons with siblings with regard to parental treatment. The sibling comparison hypothesis was tested on a sample of 516 two-child families by examining whether gender, self-esteem, and emotionality-which have been found in previous research to moderate social(More)
The degree to which child temperament moderates genetic and environmental contributions to parenting was examined. Participants were drawn from the Nonshared Environment and Adolescent Development project and included 720 sibling pairs, ages 13.5 + 2.0 years (Sibling 1) to 12.1 + 1.3 years (Sibling 2). The sample consisted of 6 sibling types: 93 monozygotic(More)
Opioid receptors are major actors in pain control and are broadly distributed throughout the nervous system. A major challenge in pain research is the identification of key opioid receptor populations within nociceptive pathways, which control physiological and pathological pain. In particular, the respective contribution of peripheral vs. central receptors(More)
OBJECTIVE To focus attention on the critical unmet needs of children and adolescents with mood disorders and to make recommendations for future research and allocation of healthcare resources. METHOD The 36-member Consensus Development Panel consisted of experts in child/adolescent or adult psychiatry and psychology, pediatrics, and mental health(More)
This study uses 2 samples of adolescents and parents--the child-based Nonshared Environment in Adolescent Development project (NEAD; D. Reiss, J. M. Neiderhiser, E. Hetherington, & R. Plomin, 2000; N = 395 families) and the parent-based Twin and Offspring Study in Sweden (TOSS; N = 909 twin family pairs)--to investigate passive and evocative(More)
The present study examined the developmental course of the age-related hearing loss and its consequences on the expression of acoustic startle reflex (ASR) and prepulse inhibition (PPI) generated by white-noise bursts in 129S2/SvPas (129) and C57BL/6J (C57) mouse strains and their F(1) hybrids. Auditory brainstem responses (ABR), ASR and PPI were assessed(More)
