Supply and demand matching of VET skills - a regional case study
Lopes, Ana Sofia; Rebelo, Isabel; Santos, Rui; Costa, Rogério; Ferreira, VítorThe proper alignment between supply of Vocational Education and Training (VET) and labour market demand is critical to successfully achieve VET’s main benefits, such as reduction of academic dropout rates, unemployment reduction and economic growth. This article presents the study carried out in Leiria region (Portugal) to define VET areas priorities at the secondary education level. A mixed methodology was app...
Conceptions of computer mediated learning in University students
Rebelo, Isabel; Duarte, AntónioThis study had the goal of knowing about students’ representations on computer mediated learning by testing the eventual replication, concerning the idea of the computer as a learning medium, of the variants of conceptions of learning proposed by “phenomenography”. The study was based on semi?structured interviews centred on four dimensions of conceptions of learning with the computer: referential dimension (w...
Electrochemical determination of 8-oxoguanine in the presence of uric acid
Rebelo, Isabel; Piedade, José António P.; Brett, Ana Maria OliveiraThe electrochemical oxidation of 8-oxoguanine (8-oxoG) in the presence of uric acid (UA) was studied by differential pulse voltammetry over a wide pH range (1-12). The results showed that both compounds follow a pH-dependent oxidation mechanism that involves two electrons and two protons corresponding to reversible charge transfer reactions. The difference between the peak potential for the oxidation of each an...
