In this paper we analyze a nonlinear generalization of the Black-Scholes equation for pricing American style call option in which the volatility may depend on the underlying asset price and the Gamma of the option. We propose a novel method of pricing American style call options by means of transformation of the free boundary problem for a nonlinear Black-Scholes equation into the so-called Gam...

The aim of our research is to automatically deduce the learning style from the analysis of browsing behaviour. To find how to deduce the learning style, we are investigating, in this paper, the relationships between the learner‟s navigation behaviour and his/her learning style in web-based learning. To explore this relation, we carried out an experiment with 27 students of computer science at t...

According to many recent studies the effect of learning style on academic performance has been found to be significant and mismatch between teaching and learning styles causes learning failure and frustration. Thus balancing the teaching style and the students’ learning style is very important. When emphasizing the individual learning processes, web-based learning offers a good opportunity for ...

Objective: The aim of this study was to determine the learning styles of fifth-year medical students who attended the ophthalmology course and to also determine the correlation with their academic performance. Methods: Kolb’slearning style and neurolinguistic programming (NLP) questionnaires were applied and related tothe final grades obtained. The variables were analyzed using Pearson’s r test...

Maintenance of a balance between commensal bacteria and the mucosal immune system is crucial and intestinal dysbiosis may be a key event in the pathogenesis of colorectal cancer (CRC). The toll-like receptor 4 (TLR4) is an important pattern-recognition receptor that regulates inflammation and barrier function in the gut by a mechanism that involves activation of the nuclear factor-κB (NF-κB) tr...

The aim of the present study was to investigate if any changes exist in the learning styles of medical students over time and in relation to different curriculum models with these learning styles. This prospective cohort study was conducted in three different medical faculties, which implement problem-based learning (PBL), hybrid, and integrated curriculum models. The study instruments were Kol...

Recent efforts to understand and predict the onset and maintenance of aggression have considered the heterogeneity of this behavior. Dodge (1980) and others, have suggested a distinction in aggression based on two primary subtypes: reactive and proactive aggression. The form, severity and persistence of these aggressive subtypes may depend on an on-going interaction between individual character...

a significant share of classroom interaction occurs between teachers and language learners. therefore, the individual characteristics of teachers could play facilitative or impeding roles thus encouraging or discouraging learners from getting engaged in interaction and meaning negotiation attempts when interacting with their teachers. surprisingly however, this area has attracted scant attentio...

We explored direct, mediated, and moderated associations between adult attachment style and marital satisfaction using a community-based sample of 73 married women. Continuous ratings of secure, avoidant, and ambivalent attachment styles were related to levels of marital satisfaction. However, psychological distress mediated the association between secure attachment and marital satisfaction, an...
