The purpose of this study was to explore dieting practices of female Palestinian college students. Participants ( = 410) were selected by cluster-sampling from 4 Palestinian universities. A regression model investigated dieting using: body mass index (BMI); body satisfaction; self-esteem; dress style; exercise; sociocultural factors; residence; strength of faith; perceived impact of weight on s...

BACKGROUND The main aim of this study was to explore the relationships between personal self-concept and satisfaction with life, with the latter as the key indicator for personal adjustment. The study tests a structural model which encompasses four dimensions of self-concept: self-fulfillment, autonomy, honesty and emotions. METHOD The 801 participants in the study, all of whom were aged betw...

Constraint satisfaction is the core of a large number of problems, notably scheduling. Because of their potential for containing the combinatorial explosion problem in constraint satisfaction, local search methods have received a lot of attention in the last few years. The problem with these methods is that they can be trapped in local minima. GENET is a connectionist approach to constraint sat...

This study investigated the magnitude of the relationships between eight school climate domains and a measure of global school satisfaction among 2,049 middle and high school students. Tests of moderator effects were conducted to determine if the magnitude of the relationships between the school climate domains and school satisfaction differed as a function of students’ gender, grade, age, GPA,...

BACKGROUND Verbal harassment, such as bullying and hate speech, has received considerable attention recently, but less is known about weight-based teasing and its potential harmful effects on young people's psychosocial well-being. OBJECTIVE To determine the associations of weight-based teasing and body satisfaction, self-esteem, depressive symptoms, and suicidal ideation and suicide attempts...

We give a complexity dichotomy for the problem of computing the partition function of a weighted Boolean constraint satisfaction problem. Such a problem is parameterized by a set Γ of rational functions, each of which assigns a weight to each variable assignment. Our dichotomy extends previous work in which the weight functions were restricted to being non-negative. We represent a weight functi...
