In outcomes-based education (OBE), outcomes, not content, must be assessed. Formative assessment takes place during the teaching and learning process, whereas summative assessment refers to assessment that is used for making a judgment about the achievement of an outcome. Authentic assessment mirrors the real world and is integrated with learning as learners are viewed as active participants in...

Our study examines the group decision-making process and proposes a multi-criteria framework for e-commerce solution investment in information technology (IT) portfolios. First, the evaluation criteria that fit in the IT evaluation context are constructed. Second, the Fuzzy Analytic Hierarchy Process (FAHP) is employed to determine the weights of decision criteria and the benefit score to the c...

This paper is a report on the findings of a study conducted on the implementation of a portfolio system at the University of Kentucky. Interviews were conducted with faculty members and university supervisors about the use of a portfolio management tool that had been implemented in the teacher education program. Factors such as small program size and ability to engage in frequent interpersonal ...

Organizations must take decisions on how to allocate resources to `go/nogo' projects to maximize the value of their project portfolio. Often these decisions are complicated by several value criteria, multiple resource types and exogenous uncertainties that in uence the projects' values. Especially when the number of projects is large, the e ciency of the resource allocation and the quality of t...

A valuation model is presented for options on stocks for which BlackScholes arbitrage does not entirely eliminate risk. The price dynamics of a portfolio of options and the underlying security is quanti ed by requiring that the excess reward-to-risk ratio of the portfolio be identical to that of the underlying stock: excess return risk portfolio = excess return risk stock : The nonlinear evolut...

A mathematical multi objective model for the selection of a portfolio of investment is presented and its application in the Mexican Stock Exchange (BMV). The multi objective model proposed is based on our mathematical model of linear programming recently published. Our multi object model is developed whereas the e-constrains method, with which the model remains linear and each iteration the SIM...
