We define the problem of group identification in a fuzzy environment. We concentrate on the case where the society is required to self-determine the belongingness of each member to a specific group, characterized by a single attribute. In general terms, this case consists of a collective identity issue that can be regarded as an aggregation problem of individual assessments within a group. Here...

To avoid distorting the visual information in an image, smoothing algorithms must preserve the details. However, some fine details are frequently treated as noise by general smoothing filters. In such situations,we encounter the problem of ambiguity or uncertainty between noise and fine details. A new nonlinear smoothing method using fuzzy reasoning techniques is proposed. Fuzzy set theory [1,2...

A character recognition system using soft computing techniques is presented in this paper. We define fuzzy sets on the Hough transform of each character pattern pixel and synthesize additional fuzzy sets by t-norms. The heights of these t-norms form an n-dimensional feature vector for the character. A 3n-dimensional vector is then generated from the n-dimensional feature vector by defining thre...

The concept of fuzzy set, which was published by Zadeh in his classic paper [24] of 1965, was applied by many researchers to generalize some of the basic concepts of algebra. The fuzzy algebraic structures play a central role in mathematics with wide applications in many other branches such as theoretical physics, computer sciences, control engineering, information sciences, coding theory, topo...

During the last 10 years or so, there has been a large movement within the field of computerised image analysis to avoid crisp segmentation into interesting and non-interesting regions and instead using a fuzzy approach, where points are assigned membership values related to the degree of belongingness to the structure of interests. The segmented fuzzy object is used in the subsequent analysis....

The dualistic model of passion was investigated in a work context. This model states that individuals may develop either a harmonious or obsessive passion for a valued activity. We hypothesized that harmonious passion for work would be positively related to job satisfaction through higher perceptions of belongingness at work. Results from a survey conducted with 278 Norwegian employees showed t...

Do different forms of uncertainty account for different procedural fairness effects? We hypothesized that general uncertainty accounts for fairness judgments, whereas belongingness uncertainty accounts for group identification. Experiment 1 manipulated general versus belongingness uncertainty. Participants in the general uncertainty condition regarded the procedures as fairer when they were gra...

Fuzzy co-clustering is a method that performs simultaneous fuzzy clustering of objects and features. In this paper, we introduce a new fuzzy coclustering algorithm for high-dimensional datasets called Cosine-Distancebased & Dual-partitioning Fuzzy Co-clustering (CODIALING FCC). Unlike many existing fuzzy co-clustering algorithms, CODIALING FCC is a dualpartitioning algorithm. It clusters the fe...

The relationship between school belongingness and mental health functioning before and after the primary-secondary school transition has not been previously investigated in students with and without disabilities. This study used a prospective longitudinal design to test the bi-directional relationships between these constructs, by surveying 266 students with and without disabilities and their p...

Suicide is ranked as the tenth leading cause of death for all ages in the United States (Centers for Disease Control and Prevention, 2012). Joiner's (2005) interpersonal theory of suicide stated thwarted belongingness-the feeling of being alienated from others-and perceived burdensomeness-the feeling of being a liability to others-are the primary proximal factors leading to suicidal desire. The...
