Abstract
Throughout an academic year, in every Educational Institution, a considerable number of days and human resources are spent trying to manually perform a task that can be automated and optimized - the creation of timetables. In a time where the need to reduce costs has become part of the day to day reality of all Educational Institutions, it is unthinkable to continue working with this kind of approach. The automatic creation of timetables for Education is one of the most studied problems by the scientific community. However, almost all studies have been based on very simplified models of reality, not having thus a practical application. This paper presents an automated and optimized generator of timetables and the results obtained with its use under real conditions.

Abstract
Risk is inherent in all software projects. To manage and control them represents gains for the development and success of projects. The risk management goal is to control, in a continue way, the risks that arise in all the phases of projects, and it's considered determinant to the projects' success. The risk management process is defined through models that specify the activities to accomplish during the project, with the aim to eliminate or minimize the impact of risks. Given the popularity of agile approaches, agile risk management has become central, because agile methodologies by themselves don't give an answer to the risks that might arise in a software project. The work presented in this article has a goal the definition of a risk management model, suited to agile development, in order to improve the existing risk management.

Abstract
The main purpose of this article is to study the antecedents (internal market orientation) and the consequences (innovation, organizational commitment and performance) of market orientation in industrial SMEs. This article follows a new approach: instead of analyzing the responses of CEOs to a questionnaire, commercial and marketing functional managers were addressed. Consequently, this is the first study of its kind involving industrial SMEs addressing those who implement the marketing strategy instead of those who define it. Based on 154 valid answers, the conclusions are that, at a signifi cant level of 1%, the internal market orientation infl uences positively the external market orientation, the external market orientation infl uences innovation and innovation, in its turn, infl uences business performance. Moreover, market orientation and organizational commitment only infl uence performance at a 5% signifi cance level.

Abstract
This study analyses the relationship between ownership concentration and firm value. Our findings, based on a dynamic panel data analysis, show that there is a quadratic relationship between the company's value and its ownership concentration. Additionally, our evidence suggests that for countries where investor protection is low, the relationship follows an inverted 'U' shape, while for countries where investor protection is high, the relationship is positive and nearly linear. Moreover, the influence of blockholders depends on their identity. This paper highlights the superior performance of family firms in controlling agency problems, a situation which contrasts vis-'-vis institutional shareholders. Finally, we report that the family effect is nonlinear. Indeed the positive effect starts to taper off at around 30% of ownership being somewhat smaller and less statistically significant between 30% and 50% of ownership. Moreover, in contrast to recent studies, the family effect is more pronounced in majority-controlled firms. © 2013 Inderscience Enterprises Ltd.

Abstract
The rapid and all-encompassing changes in regional and world wine markets have stimulated us to carry out this study. Accordingly, based on the competitiveness of an important Port wine producer in Portugal, this article analyzes a strategic alliance between this company and another important multinational one that is present in many different worldwide distribution markets. Basically, the article seeks to understand, on the one side, the impact of a strategic alliance on a small Port wine producer when becoming involved with a multinational company, and, on the other hand, to identify differences, before and after the alliance, to the markets where the small company was made present. This work is centered on a case study and involves the use of econometrics methodologies that analyze panel data, in order to grasp differences of strategic pre- and post-alliance actions. The conclusions are important, since they allow one to compare, on one hand, difference between the company's performance over two different time horizons. On the other hand, econometrics methods are robust, since they allow one to come to relational conclusions, keeping the case study in mind.
