Resumen. tiva 0 la formación para la adquisición de la cultura emprendedora se constituye como uno de los pilares centrales que deben guiar las políticas educativas de los países europeos. Con el RD 1147/2011, de 29 de julio, se introdujo el módulo profesional de empresa e iniciativa emprendedora. También la Ley 14/2013, de 27 de septiembre de apoyo a los emprendedores y su internacionalización, incorpora medidas para que los jóvenes adquieran, a través del sistema educativo, las competencias y habilidades requeridas para emprender.

This paper is intended as an exploration of university faculty and students' perceptions of a number of dimensions involved in the written composition of academic texts. We analysed the responses to scale 3 in the European Writing Survey (EUWRIT) (in its Spanish version: Encuesta Europea sobre la Escritura Académica, EEEA) by a group of social science and humanities students (n = 1,030) and faculty (n = 230) from nine Spanish universities. We then examined the similarities and differences in their perceptions and established a factorial structure of the different dimensions underlying the writing process. The data indicate that both groups concur in the value assigned to both changing ideas in the course of the composition process (although this process seems to be understood differently by each group) and the revision and feedback processes. The students, however, claim to be involved in more planning and previous reading activities than the teachers perceive them to be. The significance of these results for a processoriented perspective in academic writing is discussed.

This thesis work and my degree would not have been possible without the help and support of my advisor, Dr. Sonia López Alarcon. Her guidance has helped me grow as a student and researcher, providing the foundation for the rest of my academic career. Without the feedback from my committee members, Dr. Muhammad Shaaban and Dr. Khireesha Kudithipudi, this document and my degree would not have been finished. I would also like to thank Dr. Julio Sahuquillo Borrás for his invaluable help while living across an ocean. A thanks to Paul Mezzanini in Research Computing, without his resources I would not be able to have the comprehensive results that I have, and who raised the priority of my jobs so I could get results when it mattered. I would also like to thank Dave Warth, my track coach and friend who helped to teach me how to be mentally strong. Finally, I would like to thank the Computer Engineering department for putting up with me for so many years. v

The spectral broadening of the pump pulse through self phase modulation in a time domain distributed Brillouin sensor is demonstrated to have a non-negligible detrimental effect, leading to a doubling of the effective gain linewidth after some 20 km in standard conditions. The theoretical modeling is fully confirmed by experimental results.
