Pervasive multimedia guidance system for special needs passengers on public transport

[EN] This article presents a practical case of a pervasive multimedia guidance system for public transport passengers. In order to provide useful information to passengers, the system is capable of operating and adapting spontaneously to the different parts of a public transport network, using local data communication technologies. The multimedia data provided by the system are highly accessible, and adapt to the passengers' preferences, and are consequently suitable for special needs passengers. To this end, a paradigm of pervasive computing has been applied.

Education and wages of vocational training graduates

[EN] This paper attempts to explain individual variation in wages by estimating different wage equations. The study has two goals: first, to analyze the effect of years of schooling on the wages of vocational training graduates using a more precise measure for schooling than that commonly used in wage equations; and second, to analyze the effect on these wages of the match or mismatch between the knowledge and the skills acquired in the schooling and the needs of the job. The analysis shows that knowledge and skills acquired through vocational training (over-/under- education and over-/under- skilling), have a statistically significant influence on wages.
