In this paper, we present structure of the fixed point set results for condensing set-valued map. Also, we prove a generalization of the Krasnosel'skii-Perov connectedness principle to the case of condensing set-valued maps.

We investigate the connectedness of clash-free timetables with respect to the Kempe-exchange operation. This investigation is related to the connectedness of the search space of timetabling problem instances, which is a desirable property, for example for two-step algorithms using the Kempe-exchange during the optimization step. The theoretical framework for our investigations is based on the s...

The goal of this exploratory research is to examine the inter-linkage among Internet connectedness, information literacy, and quality of life. Results from a telephone survey, based on a probability sample of 756 Internet users, found that Internet connectedness is not related to quality of life. However, there is a significant relationship between Internet connectedness and information literac...

Two studies were conducted to examine mental representations of loneliness and social connectedness. In Study 1, young adults (N = 2,531) completed the revised UCLA Loneliness Scale (R-UCLA scale) and demographic questionnaires. An exploratory factor analysis of the R-UCLA scale on half the sample revealed a three-dimensional conceptual structure that generalized across gender. This mental repr...

Individuals who are low (compared with high) in attachment-related avoidance rely on social bonds to regulate distress, and the authors hypothesized that nostalgia can be a repository of such social connectedness. Studies 1-3 showed a positive association between loneliness and nostalgia when attachment-related avoidance was low, but not when it was high. Study 4 revealed that low-avoidance ind...

Abstract. Objective: The authors compared collegiate athletes and nonathletes to see whether there were significant differences in the perceived levels of social connectedness, self-esteem, and depression and if an interaction among the variables of athlete status, gender, GPA, BMI, and levels of weekly exercise and sleep were associated with depression symptomatology. Participants: Participant...

It is a challenging task to automatically segment glioblastoma multiforme (GBM) brain tumors on T1w post-contrast isotropic MR images. A semi-automated system using fuzzy connectedness has recently been developed for computing the tumor volume that reduces the cost of manual annotation. In this study, we propose a an ensemble method that combines multiple segmentation results into a final ensem...
