The Markowitz's objective functions, Value-at-Risk and Conditional Value-at-Risk, are largely used tools in the financial Market for portfolio optimization. This paper tries to analyze these functions having as a target to adapt them for application in non-financial assets portfolios. The paper uses as an example the Electricity Market to analyze and optimize a fictitious investment portfolio of a possible electric power utility. Showing that, besides being possible, which considerations must be taken and which analysis must be made to apply the Modern Portfolio Theory in the non-financial universe

The objective of this study is to present an analysis of students performance in public schools of Araraquara in relation to the proficiency in mathematics, addressing the Sistema de Avaliação de Rendimento Escolar do Estado de São Paulo (SARESP), which is an important tool for support the Secretaria Estadual da Educação in definitions focused on educational policies. To perform the analysis of students performance were considered notes in math tests, achieved by students from the third grade of high school in eleven state public schools of Araraquara. To achieve the proposed objective, were used data from SARESP for the period between 2008 and 2011, made available by the State Secretariat of Education (SEE). The results showed that students in the third grade of high school of public schools in Araraquara are in the worst levels of proficiency in mathematics considered by SARESP. This result demonstrates an urgent need to seek explanations and ways to overcome this situation.
