This paper explores and compares mature students' perspectives and experiences of face-to-face and online collaborative learning using a Problem Based Learning approach in an undergraduate Management Education module for Early Years Education and Care Managers. Data was collected for a face-to-face group (N=17) and an online group (N=9) on perceptions of learning outcomes achieved and reflectiv...

This paper discusses the development and implementation of a set of online teaching and learning modules for the modeling and solution of simple linear Ordinary Differential Equations (ODEs). The paper describes how constructivist principles are used in the development of these modules and how in-built assessment has been used to enhance student learning. A discussion of the module structure is...

The eCIRCUS (Education through Characters with Interactive Role-playing Capabilities that Understand Social interaction) project aims to develop an anti-bullying software, FearNot!, and evaluate its effectiveness in the classroom. This paper presents findings from two evaluations conducted during the 2006 National I-Power-I Anti-bullying Conference for Young People. Participants interacted with...

We consider the problem of evaluation of the weight enumerator of a binary linear code. We show that the exact evaluation is hard for polynomial hierarchy. More exactly, if WE is an oracle answering the solution of the evaluation problem then P = P. Also we consider the approximative evaluation of the weight enumerator. In the case of approximation with additive accuracy 2, α is constant the pr...

One of the fundamental problems of multi-party computation is Oblivious Polynomial Evaluation. In that problem, that was introduced by Naor and Pinkas, Alice has a polynomial P (x) and Bob has a point α. The goal is to allow Bob to compute P (α) so that Alice remains oblivious of α and Bob of P (x), apart from what is implied by P (α) and α. We introduce the multivariate version of this problem...

the present study aimed to determine the effects of 12 weeks of aerobic exercise in different times of day on some cardiovascular risk factors in overweight men. 40 non-athletes, overweight men with an average age of 22.25±2.45 years old and bmi of 30.06±2.42 kg/m2 were randomly allocated to four groups of morning and evening aerobic training and control. morning and evening training groups per...

background : recurrent aphthous stomatitis (ras) is one of the most common mucosal ulcerative of oral cavity. role of immune system, especially cytokines in immunopathogenesis of aphthous stomatitis was not highly considered. the aim of this study was to evaluate the levels of salivary cytokines, including vegf-r3, tgf-&beta1;, tnf-α, and il-17a/f in patients with ras in two clinical stages, ul...

In this paper we present criteria for an n-quasigroup to be isotopic to an n-group. We call a such n-quasigroup G−n-quasigroup. Applications to functional equations on quasigroups are presented in a subsequent paper. 2000 Mathematics Subject Classification: 20N15. Some important n-quasigroup classes are the following. An n-quasigroup (A,α) of the form α(x1 ) = n ∑ i=1 fi(xi)+a, where (A,+) is a...

OBJECTIVES/HYPOTHESIS Obstructive eustachian tube (ET) dysfunction is a common condition associated with various otologic symptoms. The current lack of a diagnostic gold standard makes diagnosis and evaluation at follow-up difficult. The aim of the study was to determine the value and discriminative power of the seven-item Eustachian Tube Dysfunction Questionnaire (ETDQ-7) in patients with obst...
