The literature on adolescent development refers to the adolescent’s need to be connected to others in a meaningful way. However, research on adolescent connectedness in the South African context is limited, particularly with regard to gender influences. This exploratory, descriptive research project therefore aimed at investigating gender differences in the connectedness of Grade 8 and Grade 11...

The notion of separatedness degrees of L-fuzzy subsets is introduced in L-fuzzy topological spaces by means of L-fuzzy closure operators. Furthermore, the notion of connectedness degrees of L-fuzzy subsets is introduced. Many properties of connectedness in general topology are generalized to L-fuzzy topological spaces.

Many have the intuition that for a conditional to be true, there must exist some kind of connection between its antecedent and its consequent. We investigated experimentally the prospects for spelling out the connection in terms of inference. Participants were shown or given by description a series of fourteen numbered color patches ranging from blue to green. They were then asked to evaluate c...

There is a strong tendency in science to opt for simpler and more unified hypotheses. A view that has often been voiced is that such qualities, though aesthetically pleasing or beautiful, are at best pragmatic considerations in matters of choosing between rival hypotheses. This essay offers a novel conception and an associated measure of unification, both of which are manifestly more than just ...

It is proved that the phase shift of a polarized neutron interacting with a spatially uniform time-dependent magnetic field, demonstrates the same physical principles as the magnetic Aharonov-Bohm effect. The crucial role of inert objects is explained, thereby proving the quantum mechanical nature of the effect. It is also proved that the nonsimply connectedness of the fieldfree region is not a...

Lifetime from: 1997 Lifetime to: 2000 Short description: We developed an image processing method for MRI intensity standardization. We also introduced new, fast implementations of the fuzzy connectedness algorithm that allows segmentation at interactive speeds. We developed a new segmentation "workshop" for brain MRI segmentation using standardized MR images and the fast fuzzy connectedness alg...

The results of behavioral experiments typically exhibit inconsistent connectedness, i.e., they violate the condition known as “no-signaling,” “no-disturbance,” or “marginal selectivity.” This prevents one from evaluating these experiments in terms of quantum contextuality if the latter understood traditionally (as, e.g., in the Kochen-Specker theorem or Bell-type inequalities). The Contextualit...

For decades, scholars have wrestled with the notion that old age is characterized by social isolation. However, there has been no systematic, nationally representative evaluation of this possibility in terms of social network connectedness. In this paper, the authors develop a profile of older adults' social integration with respect to nine dimensions of connectedness to interpersonal networks ...

BACKGROUND Few studies have explored risk factors for poor mental health in Ugandan primary schools. This study investigated whether individual- and contextual-level school-related factors including violence from school staff and other students, connectedness to school and peers, as well as school size and urban/rural location, were associated with mental health difficulties in Ugandan children...
