This paper treats risk based on the notions of credibility measure and credibility expected value. Firstly, the paper derives and discusses the credibility expected value. Secondly, the paper presents a new method of analysis of possibilistic portfolios. The new step is a construction by which with a possibilistic portfolio one associates a probabilistic portfolio. The problem solving of possib...

AIM Portfolios are often used as an instrument with which to stimulate students to reflect on their experiences. Research has shown that working with portfolios does not automatically stimulate reflection. In this study we addressed the question: What are the conditions for successful reflective use of portfolios in undergraduate medical education? METHODOLOGY/RESEARCH DESIGN: We designed a por...

This preface reviews the importance of and approaches for arriving at an assessment and evaluation of open source projects. It then proposes a solution based on an analysis of their growth rates in several aspects. These include: code base, developer number, bug reports, and downloads. Based on this analysis and assessment, a well-known portfolio planning method, the BCG matrix, is employed for...

In this paper, we propose to arrive at an assessment and evaluation of open source projects based on an analysis of their growth rates in several aspects. These include code base, developer number, bug reports and downloads. Based on this analysis and assessment, a well-known portfolio planning method, the BCG matrix, is employed for arriving at a very broad classification of open source projec...

The students of the university of teacher education St.Gallen (PHSG, Switzerland) document aspects of their learning process affiliated with their first experiences in a practical training class during their first academic year linked with an E-Portfolio (Weblog). The first presented study reports findings (n= 129; questionnaire; Man Withney UTests; Wilcoxon Signed Rank Tests) concerning the at...

BACKGROUND The assessment of the anesthesia course in our university comprises Objective Structured Clinical Examinations (OSCEs), in conjunction with portfolio and multiple-choice questions (MCQ). The objective of this study was to evaluate the outcome of different forms of anesthesia course assessment among 5(th) year medical students in our university, as well as study the influence of gende...

in traditional portfolio selection model coefficients often are certain and deterministic, but in real world these coefficients are probabilistic. so decision maker cannot estimate them exactly. financial optimization is one of the most attractive areas in decision under uncertainty. in the portfolio selection problem the decision maker considers simultaneously conflicting objectives such as ra...

The concept of a teaching portfolio in higher education is not new. However, for many teaching staff the concept of a digital or electronic teaching portfolio is very new a perspective that cannot be ignored. Academic developers have a role to play in their institutions in making the concept of a digital portfolio understood by staff, and making transparent the many and varied options available...
