Curricula Design Based on Competencies in Romanian Higher Education

With the Bologna Declaration, educational systems of a great number of European countries are living a changing process, with the common goal to create a European space for higher education in order to enhance the employability and mobility of citizen and to increase the international competitiveness of European higher education. In our paper we propose a new vision on competencies system design in Romanian higher education. We explain how educational system can be transformed and adapted based on companies’ requests and also on European educational requirements. Other objectives of our paper are to define the basic competencies of graduated students after Bologna process, to define the competencies required by employers to graduated students and to classify general competencies for each year of study. This new vision and competencies design are able to harmonize academic requirements and labor market demands in Romania with European space in the context of labor migration in Europe.

A Promotion Model in a Small Collectivity

Mathematically we can say that people become unhappier with the time if they keep their jobs. To solve this problem we will analyze the evolution of wages in relation with the effort level when the employee maintains his job or he is promoted. We will suppose that we have a small collectivity and we will have lifetime employment and we will prove that the promotion model is based on a Markov chain.
