Adolescents' supportive relationships with parents, teachers, and peers were examined in relation to motivation at school (schooland class-related interest, academic goal orientations, and social goal pursuit). On the basis of 167 sixth-grade students, relations of perceived support from parents, teachers, and peers to student motivation differed depending on the source of support and motivatio...

In this paper, we address the problems of adaptive schema mappings between different peers in peer-to-peer network and searching for interesting data residing at different peers based on such mappings. We begin by classifying the shared schema of each peer into a taxonomy of relation categories and attribute categories. We then propose our adaptive schema mapping by selectively probing the shar...

The aim of this study was to test whether the associations between adolescent-parent attachment and externalizing problem behavior of adolescents were mediated by adolescent cognitive distortions, self-esteem, parental monitoring and association with deviant peers. A total of 102 adolescents (71 % male; aged 12-19 years) at risk for developing delinquent behaviors reported on attachment, parent...

Background The chronic genetic blood disorder, thalassemia, affects Quality of life (QOL) negatively. Regarding this, if adolescences with thalassemia are treated well, they will grow into an adult who will have a good potential for participating in society. Objectives: to determine the strongest predictor of QOL, compare QOL between the adolescents with beta-type major and their peers in Abada...

On-line forums or bulletin boards provide opportunity and potential for collaborative work, dialogue and study that can increase the flexibility of learning while motivating participants. By enabling peer-to-peer interaction, online bulletin boards can support the essential elements of a learning conversation by providing scope for discussion, dialogue and interaction. The structure of the bull...

This study tested a person-group dissimilarity model for the relation between peer preference on the one hand, and bullying and victimization on the other. This model accounts for both individual and group (i.e., classroom) factors and postulates that children will be rejected by their peers when they display behaviors that deviate from the group norm. We tested the model in a sample of 2,578 e...

Here we study the following system of difference equations xn = f −1 ( cnf(xn−2k) an + bn ∏k i=1 g(yn−(2i−1))f(xn−2i) ) , yn = g −1 ( γng(yn−2k) αn + βn ∏k i=1 f(xn−(2i−1))g(yn−2i) ) , n ∈ N0, where f and g are increasing real functions such that f(0) = g(0) = 0, and coefficients an, bn, cn, αn, βn, γn, n ∈ N0, and initial values x−i, y−i, i ∈ {1, 2, . . . , 2k} are real numbers. We show that t...
