A system of interacting elements can be represented by a directed network so that elements are nodes and interaction between two elements is an arc. Conventionally, each node is just a point, each arc represents some kind of interaction between two nodes and nothing more after the system is mapped to a directed network. However, in many real systems, each element has its own intra-node process ...

This study presents an exploratory, cross-sectional investigation of factors associated with internalizing emotional and behavioral problems (anxiety/depression, emotional withdrawal, and somatic complaints) in a sample of adolescents displaced by the war in Chechnya and interviewed in the fall of 2000. Social support and connectedness with family, peers, and the larger community were given par...

Economic connectedness can be defined as the degree of internal connectedness of interdependence between the sectors of an economy. In input-output models intersectoral connectedness is a crucial feature of analysis, and there are many different methods of measuring it. These measures are believed to be important structural indicators, helpful in model estimation. Also, such measures could be a...

BACKGROUND The relationship between policy networks and policy development among local health departments (LHDs) is a growing area of interest to public health practitioners and researchers alike. In this study, we examine policy activity and ties between public health leadership across large urban health departments. METHODS This study uses data from a national profile of local health depart...

In many taxa, individual social traits appear to be consistent across time and context, thus meeting the criteria for animal personality. How these differences are maintained in response to changes in population density is unknown, particularly in large mammals, such as ungulates. Using a behavioral reaction norm (BRN) framework, we examined how among- and within-individual variation in social ...

School connectedness (i.e., the extent to which students feel accepted, valued, respected and included in the school) has recently surfaced as one of the most important predictors of adolescent mental health (particularly depressive symptoms). Thus it is now vital to understand predictors of school connectedness. The school environment is an established predictor, but we set out to examine whet...

Autism is a lifelong disorder, defined by deficits in social interactions and flexibility. To date, diagnostic markers for autism primarily include limitations in social behavior and cognition. However, such tests have often shown to be inadequate for individuals with autism who are either more cognitively able or intellectually disabled. The assessment of the social limitations of autism would...

We tested hypotheses that greater connectedness to parent(s) is associated with lower risk for nonlethal suicidal thoughts and behavior (STB), termed direct protective effects, and that parent connectedness serves to moderate (lower) the risk for STB associated with psychopathology including major depressive episode (MDE), termed moderating protective effects. Independent samples of children an...
