In a globalized world characterized by transnational migration flows as an inevitable consequence of the increased mobility of individuals, coping with differences and with cultural discontinuity has become the main challenge in the education and training sector at all levels. This book is addressed to professionals in vocational education and training in an attempt to provide suggestions on innovative methods and intercultural approaches for inclusive, continuous education. Starting from the achievements of the I-VET European project, led by an international consortium of Universities and training organizations, the book traces the broad, multi-disciplinary epistemological framework underlying the proposed innovative methodology, based on experiential learning and reflective practice and the didactic choices piloted with a group of VET teachers and trainers. The focus is intercultural competence achieved through a situated and contextualized exercise of awareness about the specific situations in which differences emerge, and mutual adjustment between different frameworks, in full accordance with the constructionist approach to social interaction at the basis of the whole study.
Spectrophotometry enables one to determine, with good precision and sensitivity, almost all the elements present in small and trace quantities of any material. The method is particularly useful in the determination of non-metals and allows the determination elements in a large range of concentrations (from single % to low ppm levels) in various materials.In Separation, Preconcentration and Spectrophotometry in Inorganic Analysis, much attention has been paid to separation and preconcentration methods, since they play an essential role in increasing the selectivity and sensitivity of spectrophotometric methods. Separation and preconcentration methods have also been utilised in other determination techniques.Spectrophotometric methods which are widely used for the determination of the elements in a large variety of inorganic materials are presented in the book whilst separation and preconcentration procedures combined with spectrophotometry are also described. This book contains recent advances in spectrophotometry, detailed discussion of the instrumentation, and the techniques and reagents used for spectrophotometric determination of elements in a wide range of materials as well as a detailed discussion of separation and preconcentration procedures that precede the spectrophotometric detection.
