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...

Firm-customer digital connectedness for effective sensing and responding is a strategic imperative for contemporary competitive firms. This research-in-progress paper conceptualizes and operationalizes the firm-customer mobile digital connectedness of a smart-mobile customer. The empirical investigation focuses on mobile app users and the impact of mobile apps on customer expectations. Based on...

Connectedness of efficient solutions is a powerful property in multiple objective combinatorial optimization since it allows the construction of the complete efficient set using neighborhood search techniques. In this paper we show that, however, most of the classical multiple objective combinatorial optimization problems do not possess the connectedness property in general, including, among ot...

Research with Native Americans has identified connectedness as a culturally based protective factor against substance abuse and suicide. Connectedness refers to the interrelated welfare of the individual, one's family, one's community, and the natural environment. We developed an 18-item quantitative assessment of awareness of connectedness and tested it with 284 Alaska Native youth. Evaluation...

Our point of departure is business network dynamics and the phenomenon of mergers and acquisitions. We discuss both structural and temporal connectedness of business nets, where the merging firms are embedded in. Depending on the degree of structural connectedness (or overlapping) which can also be discussed with the help of position concept, the merger or acquisition will bring about more or l...
