School connectedness, encompassing positive feelings toward teachers and peers and a sense of belonging at school, has been touted as a critical factor in promoting student achievement and reducing youth risk behaviors. The literature has been mixed in terms of understanding the relationship between race, racial congruence and school diversity’s influence on school connectedness, particularly f...

In this paper, we present an enhancement of the fuzzy connectedness-based image segmentation method based on dynamic computation of adaptive weights for the homogeneity and the directional gradient energy functions. Adaptive weights enhance the performance and robustness of the conventional fuzzy connectedness-based segmentation while decreasing the degree of user interaction. The accuracy of t...

For a space–time, the question whether two causally related points can be joined by means of a causal geodesic has a clear physical meaning. More geometrically, geodesic connectedness ~the possibility of joining any two points by a geodesic of any causal type! is a basic property. Some techniques introduced to study geodesic connectedness are appliable to related problems of physical interest, ...

Although research has shown that loneliness in adolescents leads to higher rates of depressive symptoms, the presumed protective factor of social connectedness has not been studied in conjunction with these two constructs. The aim of the present study was to determine if social connectedness would predict lower loneliness and depressive symptoms over time in a large sample of adolescents. A lar...

Despite a growing recognition of cultural connectedness as an important protective factor for First Nations (FN) peoples' health, there remains a clear need for a conceptual model that organizes, explains, and leads to an understanding of the resiliency mechanisms underlying this concept for FN youth. The current study involved the development of the Cultural Connectedness Scale (CCS) to identi...

There is limited prospective research on the relation between school connectedness (i.e., the extent to which students feel accepted, valued, respected, and included in the school) and mental health symptoms in adolescents. A sample of 2,022 students (999 boys and 1,023 girls) ages 12 to 14 years were measured at 2 time points (12 months apart) on school connectedness and mental health symptoms...

Introduction This paper discusses the concept of 'connectedness', exploring its relationship with the concepts of 'social presence' and 'awareness', and arguing that although 'social presence' and 'awareness' have received most focus in previous research, 'connectedness' is, in fact, a more fundamental concept. 'Connectedness' is potentially a key concept in the analysis of communication and th...
