This open access volume provides an understanding of the different aspects of success, school continuity and social mobility among European Roma, including the motives justifying the high rates of school dropout and failure among this group. It offers a critical and reflexive perspective about social reality from a multidisciplinary and transversal point of view, sharing knowledge and practices in different countries about the articulations between Roma families, individuals, school and public policies. Over time, there has been an increase in the educational attainment of European citizens, but there are still persistent inequalities between Roma and non-Roma, including gender inequalities, which greatly affect Roma women. The volume explores the issue of Roma education and includes chapters from Western European, South and Central and Eastern European researchers using different theoretical and methodological perspectives. The intersection of this diversity and plurality of standpoints makes possible to obtain a comprehensive view on the education and schooling of European Roma.

The employment of printing techniques as cost-effective methods to fabricate low cost, flexible, disposable and sustainable solar cells is intimately dependent on the substrate properties and the adequate electronic devices to be powered by them. Among such devices, there is currently a growing interest in the development of user-oriented and multipurpose systems for intelligent packaging or on-site medical diagnostics, which would greatly benefit from printable solar cells as their energy source for autonomous operation. This chapter first describes and analyzes different types of cellulose-based substrates for flexible and cost effective optoelectronic and bio devices to be powered by printed solar cells. Cellulose is one of the most promising platforms for green recyclable electronics and it is fully compatible with large-scale printing techniques, although some critical requirements must be addressed. Paper substrates exist in many forms. From common office paper, to packaging cardboard used in the food industry, or nanoscale engineered cellulose (e.g. bacterial cellulose). However, it is the structure and content of paper that determines its end use. Secondly, proof-of-concept of optoelectronic and bio devices produced by inkjet printing are described and show the usefulness of solar cells as a power source or as a chemical reaction initiator for sensors.
