Concept mapping is a technique used to provide a visual representation of an individual’s ideas about a concept or set of related concepts. This paper describes a concept mapping tool using a photograph association technique (CoMPAT) that is considered to be a novel way of eliciting children’s ideas. What children at 11 years of age know about particular concepts related to microbial activity i...

This study tested whether the gender intensification hypothesis applies to relations between multiple domain-specific self-concept facets and selfesteem. This hypothesis predicts gender-stereotypic differences in these relations and assumes they intensify with age. Furthermore, knowledge about gender-related or age-related differences in self-concept–self-esteem relations might provide valuable...

We develop a Bayesian approach to concept learning for crowdsourcing applications. A probabilistic belief over possible concept definitions is maintained and updated according to (noisy) observations from experts, whose behaviors are modeled using discrete types. We propose recommendation techniques, inference methods, and query selection strategies to assist a user charged with choosing a conf...

Nowadays, offering extended warranty is considered as a lucrative source of income from the perspective of the after-sale service providers. Meanwhile, the main concern is presence or absence of base warranty and strategies adopted by the manufacturer during this period. Moreover, extended warranty structure must be responsive and customer oriented, which not only control the services cost but ...

Background: Cognitions and attitudes, especially anthropological attitudes, are influential in human behavior. Objectives: The present study was conducted to investigate the cognitive evolution of the human concept in elementary school female students and its adaptation to Piaget’s theory of cognitive development. Materials & Methods: The present research method is qualitative of deductive-ind...

Given its eminent role in student learning and development, it is important to understand how academic self-concept (i.e., how one perceives oneself in an academic context) is formed. Both internal and external comparisons are considered crucial antecedents: Students form their academic self-concept to a considerable extent by (externally) comparing themselves with others and by (internally) co...

This paper studies the performance of iterative multiuser decoding, interference cancellation, and channel estimation techniques applicable to third generation WCDMA systems. The concept uses a posteriori probabilities of code symbols to enhance detection, decoding and channel estimation in an iterative fashion. Performance is analyzed in a multi-path channel with simulations. It is seen that t...
