One problem in evaluating recent computational models of human category learning is that there is no standardized method for systematically comparing the models’ assumptions or hypotheses. In the present study, a flexible general model (called GECLE) is introduced that can be used as a framework to systematically manipulate and compare the effects and descriptive validities of a limited number ...

Introduction: The present study aimed to investigate the psychometricproperties of Grasha-Riechmann Student Learning Styles Scale.Method: The participants included 1039 students (421 students in human and 618 students in technical sciences), selected through the stratified sampling method from Tehran University. They answered the Grasha-Riechmann student learning style scale and the data was an...

This paper demonstrates the generality of the hidden Markov model approach for exploratory sequence analysis by applying the methodology to study students’ learning behaviors in a new domain, i.e., an asynchronous, online environment that promotes an explicit inquiry cycle while permitting a great deal of learner control. Our analysis demonstrates that the high-performing students have more lin...

This study presents a reservoir modeling approach to investigate the relative effects of different coalbed parameters on the migration of methane into development entries. A base coalbed reservoir model of a three-entry development section, where grids were dynamically controlled to simulate the advance of mining at a constant section advance rate, was created and calibrated for a Pittsburgh Co...

The economic model is always an abstraction from the real economy, and will not be perfectly completed as long as any kind of models. There is possibility to deny the model by new observations at any moment, because of the nature of scientific models that are just valid to the past experience[2][3]. Especially in the social science, the models are exposed to the fact that individuals and societ...

The Internet allows combining various multimedia applications in order to create a holistic online experience. Companies integrate utilitarian and hedonic elements in their Websites in order to improve their overall effectiveness and efficiency. In this exploratory research paper we present the results of a longitudinal study, in which we analyze the use of four different hedonic information te...

“Exploratory” and “confirmatory” data analysis can both be viewed as methods for comparing observed data to what would be obtained under an implicit or explicit statistical model. For example, many of Tukey’s methods can be interpreted as checks against hypothetical linear models and Poisson distributions. In more complex situations, Bayesian methods can be useful for constructing reference dis...

In recent years the digital media has influenced many areas of our life. The transition from analogue to digital has substantially changed our ways of dealing with media collections. Today‟s interfaces for managing digital media mainly offer fixed linear models corresponding to the underlying technical concepts (folders, events, albums, etc.), or the metaphors borrowed from the analogue counter...

Purpose – Exploratory learning is regarded as an important ability for developing knowledge from open environments. During the exploration, learners not only need to acquire new information based on their current interests, but also they need to form new perspectives by incorporating new knowledge into their previous knowledge. This paper seeks to address these issues. Design/methodology/approa...
