This study examined prospective mediating relations among mother-adolescent attachment security, self-worth, and risk behaviors, including substance use and violence, across ages 13-17 in a sample of 901 low-income African American adolescents. Path analyses revealed that self-worth was a significant mediator between attachment security and risk behaviors, such that earlier attachment security ...

This paper exploits a unique ongoing experiment to analyze the effects of early rearing conditions on physical and mental health in a sample of rhesus monkeys (Macaca mulatta). We analyze the health records of 231 monkeys that were randomly allocated at birth across three rearing conditions: mother rearing, peer rearing, and surrogate peer rearing. We show that the lack of a secure attachment r...

Psychoanalysts believed that early mother-child relationships form the prototype of all future relationships and the outcome of adolescents development depends on their ego-strength. Object relations theory believed that intrapsychic process mediates interpersonal interaction to develop a sense of secure self and adolescents must relinquish the internalized other in order to develop a more matu...

In this paper, we analyze the secure connectivity in Shotgun cellular systems (SCS: Wireless communication systems with randomly placed base stations) by Poisson intrinsically secure communication graph (IS-graph), i.e., a random graph which describes the connections that are secure over a network. For a base-station in SCS, a degree of secure connections is determined over two channel models: ...

BACKGROUND Experimental animal studies suggest that early glucocorticoid exposure may have lasting effects on the neurodevelopment of the offspring; animal studies also suggest that this effect may be eliminated by positive postnatal rearing. The relevance of these findings to humans is not known. METHODS We prospectively followed 125 mothers and their normally developing children from pregna...

Among primates, the intense mother-infant bond provides offspring with a lengthy period for learning from an experienced and reliable demonstrator. Since adult life differs for females and males, the expertise of mother may not be equally useful to both sexes of infant, particularly with regard to social relationships. Here, we report on differences between infant female and male stumptailed ma...

A large body of longitudinal research provides compelling evidence for the critical role of early attachment relationships in children's social, emotional, and cognitive development. It is expected that parent-child attachment relationships may also impact children's brain development, however, studies linking normative caregiving experiences and brain structure are scarce. To our knowledge, no...

F ETAL anomalies such as giant neck masses can result in perinatal death or hypoxia and anoxic brain injury due to inability to secure an airway in a timely fashion after delivery. Modern technology, ultrasound, and ultrafast magnetic resonance imaging have enabled intrauterine diagnosis and fetal interventions as a mode of therapy, thereby giving such affected fetuses a chance at survival. Ini...
