Significant changes have occurred in the developmental role of Hox genes, even within groups of arthropods that already have complex body plans and many different segment types. This is hard to reconcile with the 'selector gene' model for Hox gene function. Selector genes act as stable binary switches that direct lineages of cells to adopt alternative developmental fates. This model suggests th...

Nowadays communications, decision-making, reporting manner and hierarchy are controlled by organizational structure getting an inside into such structure means getting an insight over the whole organization. It serves as a platform for operation of plans and strategies and also determines links among personnel or executive body of the organization. In line with developments in other elements, o...

BACKGROUND Federal, provincial and municipal leaders in Canada have adopted a culture of preparedness with the development and update of emergency plans in anticipation of different types of disasters. As evident during the 2003 global outbreak of Severe Acute Respiratory Syndrome (SARS), it is important to provide support for health care workers (HCWs) who are vulnerable during infectious outb...

Proper response to stress and social stimuli depends on orchestrated development of hypothalamic neuronal circuits. Here we address the effects of the developmental transcription factor orthopedia (Otp) on hypothalamic development and function. We show that developmental mutations in the zebrafish paralogous gene otpa but not otpb affect both stress response and social preference. These behavio...

Distinguishing intentional behavior from accidental behavior is a crucial component of social cognition and a major developmental achievement. It has often been assumed that developmental changes in intentional reasoning result from a gradual sophistication in the ability to discern intentions in action. We take issue with this notion, demonstrating that data from cognitive, developmental, and ...

The social communication and compliance patterns of 63 mothers interacting with their young children who had mild developmental delays in social play and instructional tasks were examined in a longitudinal study. Results were consistent with the hypothesis that mothers appropriately adjust their social communications in accordance with children's developmental characteristics and task demands. ...

Recent findings on psychosocial and neurodevelopmental anomalies in schizophrenia patients indicate that deficits related to social cognition-the ability to act wisely in social interactions-may be important constraints on complete social and vocational recovery. Social cognition is acquired over many decades and appears to be partially independent of formal IQ and neuropsychological problems. ...
