This commentary engages with essentially contestable questions raised by the School of the Dialogue of Cultures. It focuses on questions about how theory should relate to practice and how a "dialogic" approach can involve students in simultaneously rigorous and relevant academic discussions. Disciplines Education | Educational Psychology Comments Wortham, S. (2011). Wondering about dialogic the...

This paper presents a model tha t measures the impact of political risk on portfolio investment when the political risks are multivariate and correlated across countries. The multivariate approach generalizes the single country model but retains most of its characteristics in terms of its ability to price political risk based on the stochastic process of exposure to loss and the expected freque...

The stock evaluation process plays an important role in portfolio selection because it is the prerequisite for investment and directly influences on the stock allocation. This paper presents a methodology based on Data Envelopment Analysis for portfolio selection, decision making units which can be stocks or other financial assets. First, DMUs efficiencies are computed based on input/output com...

We consider the problem of selecting investment components according to two partially opposed measures: the portfolio performance and its risk. We approach this within Markowitz’s model, considering the case of mutual funds market in Europe until July 2010. Comparisons were made on three multi-objective evolutionary algorithms, namely NSGAII, SPEA2 and IBEA. Two well-known performance measures ...

This research presents an alternative means of calculating vulnerability relations for buildings. Simulation-based fragility curves generated using a Monte Carlo simulation are usually not practical because of the large number of time-consuming analyses needed to obtain reliable statistics of the outcomes. This research implements a response surface metamodel to approximate complex analysis in ...
