Differentiating factors in ARA Groups(groups of high academic achievement) and its effects on the definition of university strategies

Tesis por compendioThis PhD thesis, which is presented in the mode of published articles, explores the differentiating factors of a High Academic Achievement Program at a public technological university in Spain and how they can affect the definition of the university strategies. The Universitat Politècnica de València (UPV), launched in the 2010-11 academic year the High Academic Achievement Groups ("Grupos de Alto Rendimiento Académico", from now on ARA Groups), characterized by a good number of courses taught using English as a medium of instruction, a small number of students in the class, and highly qualified teachers. English taught courses are a global phenomenon, associated to improved English language and internationalization skills, but it raises concerns about learning outcomes and equity (Dearden, 2014). The purpose of this study was to assess the first promotion (2010-2014) of this program at the five university bachelor degrees of the UPV that offered it. We wanted to analyze if this action has had any impact on a set of variables related to academic outcomes, international exchange programs, and business internships of the participating students in comparison with the rest of students of these degrees and hence, on their employability upon graduation. The sample consisted in the total of 3,543 students of the five degrees offering this innovation, of which 560 belonged to the ARA Groups. The first article "Effects of business internships on students, employers, and higher education institutions: a systematic review" (Sanahuja Vélez, G., and Ribes Giner, G., 2015) was published by the Journal of Employment Counselling on September 2015. The second publication consists of a Book Chapter published by Springer International Publishing on January 2017: "Intrapreneuring within a higher education institution: Introducing virtual business internships" (Sanahuja Vélez, G., Ribes Giner, G., Moya Clemente, I., 2017) in Entrepreneurial Universities (Peris-Ortiz, M., Alonso Gómez, J., Merigó Lindahl, J. M., and Rueda-Armengot, C., Eds.). The third publication is a "Systematic review of English Medium of Instruction (EMI) in higher education institutions. The case of a Business School", presented as a conference at the 2nd Seminar on Learning Internationalization: English Medium of Instruction (EMI) of the Centro de Lenguas of the Universitat Politècnica de València (March 30 and 31st, 2017) and which is currently being reviewed for its publication in its international journal. The fourth research work is the article "Enhancing student internationalization and employability in a Business School", which is presently been given full consideration for publication at the Journal of Business Management and Business Economics. The fifth article presents the core results of the empirical part of this research work and it is entitled: "Introducing a High Academic Achievement Program in a Technological University as a Social Innovation Mechanism to Enhance Graduates' Employability". This paper is currently given full consideration for publication at the journal Technovation. The overall conclusions of our research allow us to conclude that, from the academic point of view, the objectives of the High Academic Achievement Groups of the UPV were met, as results show that academic performance was enhanced. Our results also show that participation into exchange programs, at the School of Business Administration and Management and in the UPV as a whole, was almost four times higher in the ARA groups. Having in mind that better grades and international experience are directly linked to future employability and mobility of graduates, it is expected that these graduates will have a superior reception in the labor market.Esta tesis doctoral, que se presenta en el formato de artículos publicados, explora los factores diferenciadores de un Programa de Alto Rendimiento Académico en una universidad politécnica pública en España y cómo pueden afectar al diseño de estrategias universitarias. La Universitat Politècnica de València (UPV) implementó en el curso 2010-11 los Grupos de Alto Rendimiento Académico (Grupos ARA), caracterizados por un alto número de asignaturas impartidas en inglés, un número pequeño de estudiantes por clase y profesores altamente calificados. El uso del inglés como medio de instrucción (EMI) es un fenómeno global, asociado a la mejora de los conocimientos del idioma inglés y de las habilidades interculturales, pero plantea algunas preocupaciones sobre los resultados sobre el aprendizaje y la equidad (Dearden, 2014). El objetivo de este estudio fue evaluar la primera promoción (2010-2014) de este programa en los cinco títulos de grado universitario de la UPV en los que se ofertaron los Grupos ARA. Queríamos analizar si está acción ha tenido algún impacto en distintas variables relacionadas con los resultados académicos, los programas de intercambio internacional y las prácticas en empresas en los alumnos participantes, en comparación con el resto de alumnos y en consecuencia, en su empleabilidad al graduarse. La muestra consistió en un total de 3.543 estudiantes, de los cuales 560 estaban matriculados en los grupos ARA y el resto, 2.983, en los grupos regulares. El primer artículo, titulado "Efectos de las prácticas en empresas en estudiantes, empresas e instituciones de educación superior: una revisión sistemática" (Sanahuja Vélez, G., Ribes Giner, G.), fue publicado por el Journal of Employment Counseling en septiembre de 2015. La segunda publicación consta de un capítulo de libro publicado por Springer International Publishing en enero de 2017: "Intraentreprendedurismo dentro de una institución de educación superior: las prácticas en empresa virtuales" en "Entrepreneurial Universities" (Peris-Ortiz, M., Alonso Gómez, J., Merigó Lindahl, J. M., and Rueda-Armengot, C., Eds.). La tercera publicación es una "Revisión sistemática del inglés como medio de instrucción (EMI) en instituciones de educación superior. El caso de una Facultad de Administración y Dirección de Empresas", presentada como Conferencia en el 2º Seminario de Internacionalización del Aprendizaje: Inglés como Medio de Instrucción (EMI) del Centro de Lenguas de la Universitat Politècnica de València (30 y 31 de marzo de 2017) y actualmente en revisión para su publicación en la correspondiente revista internacional. El cuarto trabajo de investigación es el artículo "Promocionar la internacionalización de los estudiantes y la empleabilidad en una escuela de negocios" (Sanahuja Vélez, G., Ribes Giner, G., Moya Clemente, I.), que actualmente se considera plenamente para su publicación en el Journal of Business Management y Business Economics. El quinto artículo presenta los principales resultados de la parte empírica de este trabajo de investigación y se titula: "Introducción de un Programa de Alto Rendimiento Académico en una Universidad Tecnológica como Mecanismo de Innovación Social para Mejorar la Empleabilidad de los Graduados" (Sanahuja Vélez, G., Ribes Giner, G., Moya Clemente, I.). Este artículo ha sido enviado a la revista internacional Technovation y en la actualidad está siendo revisado para su publicación. Como resultado de nuestra investigación empírica podemos destacar los factores diferenciadores de los Grupos ARA, que son: un mayor rendimiento académico de los estudiantes, una mayor participación en programas internacionales, además de una participación en prácticas en empresas sin diferencias significativas respecto a los demás grupos, todo lo cual conduce a una mayor empleabilidad y movilidad.Esta tesi doctoral, que es presenta en la forma d'articles publicats, explora els factors diferenciadors d'un Programa d'Alt Rendiment Acadèmic en una universitat politècnica pública a Espanya i com poden afectar la definició de les estratègies universitàries. La Universitat Politècnica de València (UPV), va implementar en l'any acadèmic 2010-11 els "Grups d'Alt Rendiment Acadèmic" (Grups ARA), que es caracteritzen per un bon nombre de cursos que s'imparteixen utilitzant l'anglès com a mitjà d'instrucció (EMI), un petit nombre d'estudiants a la classe, i mestres altament qualificats. L'EMI és un fenomen global, associat a la millora dels coneixements d'anglès i de la internacionalització, però planteja preocupacions sobre els resultats de l'aprenentatge i l'equitat (Dearden, 2014). El propòsit d'aquest estudi va ser avaluar la primera promoció (2010-2014) d'aquest programa en els cinc graus universitaris de la UPV que en que s'hi va oferir. Vam voler analitzar si tenia algun impacte sobre diverses variables relacionades amb els resultats acadèmics, programes d'intercanvi internacionals i pràctiques en empreses dels 3.543 estudiants matriculats, dels quals 560 pertanyeren a eixos nous grups, i per tant en la seva futura ocupabilitat. El primer article "Efectes de les pràctiques en empreses en els estudiants, empresaris i institucions d'educació superior: una revisió sistemàtica" (Sanahuja Vélez, G., Ribes Giner, G.), va ser publicat per la revista Journal of Employment Counselling al setembre de 2015. La segona publicació consta d'un capítol de llibre publicat per Springer International Publishing, al gener 2017: "Intraentreprendurisme dins d'una institució d'educació superior: Presentació de les pràctiques virtuals en empreses" en "Entrepreneurial Universities" (Peris-Ortiz, M., Alonso Gómez, J., Merigó-Lindahl, J. M., Rueda-Armengot, C., Eds.). La tercera publicació és una "Revisió sistemàtica de l'Anglès com a mitjà d'instrucció (EMI) en les institucions d'educació superior. El cas d'una Escola de Negocis", presentada com conferència al 2ón Seminari sobre "Learning Internationalization: English as a Medium of Instruction (EMI)" del Centre de Llengües de la Universitat Politècnica de València (30 de març i el 31 de 2017) i actualment en revisió per a la seva publicació a la corresponent revista internacional. El quart treball d'investigació és l'article "Millora de la internacionalització i l'ocupabilitat dels estudiants a una Facultat de Negocis" (Sanahuja Vélez, G., Ribes Giner, G., Moya Clemente, I), que en l'actualitat ha rebut plena consideració per a la seva publicació al Journal of Business Management and Business Economics. El cinquè article presenta els principals resultats de la part empírica d'este treball d'investigació i es titula: "Introducció d'un Programa d'Alt Rendiment Acadèmic en una Universitat Tecnològica com a Mecanisme d'Innovació Social per Millorar l'Ocupabilitat dels Graduats" (Sanahuja Vélez, G., Ribes Giner, G., Moya Clemente, I.). Este article està en l'actualitat essent revisat per a la seva publicació a la revista internacional Technovation. En este article s'explora el paper d'un programa d'Alt Rendiment Acadèmic (Grups ARA) en una universitat tecnólogica pública espanyola, com a mecanisme d'innovació social, a fi de crear valor afegit en termes d'ocupabilitat. Les conclusions generals de la nostra investigació ens permeten afirmar que, des del punt de vista acadèmic, es van complir els objectius dels Grups d'Alt Rendiment Acadèmic de la UPV, ja que els resultats demostren que el rendiment acadèmic dels alumnes participants s'ha millorat. Els nostres resultats també demostren que la participació en programes d'intercanvi, a la Facultat d'Administració i Direcció d'Empreses i en la UPV en el seu conjunt, va ser gairebé quatre vegades més gran en els grups ARA.

Business internships and new technologies: a scenario for growth and innovation

[EN] Literature on traineeships recognizes beneficial effects on its main agents: students, employers, and higher education institutions. Furthermore, some authors have identified added effects when applying new technologies to the business internship experience, specially referred to improved computer skills and learning outcomes. The Faculty of Business Administration and Management of the Universitat Politècnica de València has had a remarkable increase of internships over the past years. As computer skills are being more demanded by employers in a globalized and technological world, it is expected that virtual placements and ICTs in the internship practice will be a trend in universities in the up-coming years. The management of internships of the two new Double Degrees in the Faculty of Business: Business Administration and Management + Computer Science Engineering, and Business Administration and Management + Telecommunications Engineering, could provide the perfect scenario to put into practice and to explore the possibilities of new technologies applied to internships. The recent change in the Spanish law and in the regulations of universities, such as the Universitat Politècnica de València, allows business internships to take place abroad. This could also provide an opportunity for innovation and growth, if combining internationalization with virtualization of internships.Sanahuja Velez, G.; Ribes Giner, G.; Moya Clemente, I. (2016).

Towards Sustainability in University Education. Improving University Graduates Chances of Employability by Participation in a High Achievement Academic Program

[EN] This piece of research focusses on the sustainable development goal (SDG) number four of the 2030 Agenda for Sustainable Development: quality education. The main objective of this research was to determine whether introducing a High Achievement Academic Program (ARA Groups) at a Spanish public university could enhance its graduates' employability. According to the existing scientific literature, some variables related to the students' accomplishments during college are good predictors of future employability: academic performance, participation in international exchanges, and participation in traineeships. In the empirical part of this research, our objective was to compare, using descriptive and bivariate statistical analysis, the behavior of the students of the ARA Groups and the regular ones, regarding a set of variables related to the above-mentioned predictors of employability. The outcomes allow us to conclude that ARA students performed academically better and that they participated more in international exchanges. Participation in business internships did not present significant differences, although ARA students scored higher in the employers' assessment of the internship. Our results suggest that graduates of this program will be more sought-after by companies, and therefore it contributes positively to one of the key objectives of quality higher education, which is employability, and hence to sustainable development.Moya Clemente, I.; Ribes-Giner, G.; Sanahuja Velez, G.

Retinal Pigment Epithelium and Müller Progenitor Cell Interaction Increase Müller Progenitor Cell Expression of PDGFRα and Ability to Induce Proliferative Vitreoretinopathy in a Rabbit Model

Purpose. Proliferative vitreoretinopathy (PVR) is a complication of retinal detachment characterized by redetachment of the retina as a result of membrane formation and contraction. A variety of retinal cells, including retinal pigment epithelial (RPE) and Müller glia, and growth factors may be responsible. Platelet-derived growth factor receptor alpha (PDGFRα) is found in large quantities in PVR membranes, and is intrinsic to the development of PVR in rabbit models. This study explores the expression of PDGFR in cocultures of RPE and Müller cells over time to examine how these two cell types may collaborate in the development of PVR. We also examine how changes in PDGFRα expression alter Müller cell pathogenicity. Methods. Human MIO-M1 Müller progenitor (MPC) and ARPE19 cells were studied in a transmembrane coculture system. Immunocytochemistry and Western blot were used to look at PDGFRα, PDGFRβ, and GFAP expression. A transfected MPC line cell line expressing the PDGFRα (MIO-M1α) was generated, and tested in a rabbit model for its ability to induce PVR. Results:. The expression of PDGFRα and PDGFRβ was upregulated in MIO-M1 MPCs cocultured with ARPE19 cells; GFAP was slightly decreased. Increased expression of PDGFRα in the MIO-M1 cell line resulted in increased pathogenicity and enhanced ability to induce PVR in a rabbit model. Conclusions:. Müller and RPE cell interaction can lead to upregulation of PDGFRα and increased Müller cell pathogenicity. Müller cells may play a more active role than previously thought in the development of PVR membranes, particularly when stimulated by an RPE-cell-rich environment. Additional studies of human samples and in animal models are warranted

El presente documento es el resultado del proceso de investigación que tuvo como objetivo general, articular el área de Tecnología e informática mediante estrategias pedagógicas para contribuir en la conservación del medio ambiente a través de la creación de un ambiente virtual de aprendizaje (AVA) por medio del cual los niños y niñas del Liceo Mayor de Soacha “Bienestar para todos”, específicamente de los grados 8 y 9, fortalecieran sus hábitos frente al cuidado de su entorno. Tras la implementación del AVA con una muestra aleatoria con 30 estudiantes, se logró comprobar que el uso de herramientas virtuales genera alta recordación e interés en el desarrollo de los contenidos, por tanto es mucho más efectivo para trabajar con este grupo específico de edades, haciendo uso de sus centros de interés y de esta manera propiciar el compartir de conocimientos e iniciativas

Non-standard neutrino interactions in IceCube

Non-standard neutrino interactions (NSI) may arise in various types of new physics. Their existence would change the potential that atmospheric neutrinos encounter when traversing Earth matter and hence alter their oscillation behavior. This imprint on coherent neutrino forward scattering can be probed using high-statistics neutrino experiments such as IceCube and its low-energy extension, DeepCore. Both provide extensive data samples that include all neutrino flavors, with oscillation baselines between tens of kilometers and the diameter of the Earth. DeepCore event energies reach from a few GeV up to the order of 100 GeV - which marks the lower threshold for higher energy IceCube atmospheric samples, ranging up to 10 TeV. In DeepCore data, the large sample size and energy range allow us to consider not only flavor-violating and flavor-nonuniversal NSI in the μ−τ sector, but also those involving electron flavor. The effective parameterization used in our analyses is independent of the underlying model and the new physics mass scale. In this way, competitive limits on several NSI parameters have been set in the past. The 8 years of data available now result in significantly improved sensitivities. This improvement stems not only from the increase in statistics but also from substantial improvement in the treatment of systematic uncertainties, background rejection and event reconstruction

IceCube Search for Earth-traversing ultra-high energy Neutrinos

The search for ultra-high energy neutrinos is more than half a century old. While the hunt for these neutrinos has led to major leaps in neutrino physics, including the detection of astrophysical neutrinos, neutrinos at the EeV energy scale remain undetected. Proposed strategies for the future have mostly been focused on direct detection of the first neutrino interaction, or the decay shower of the resulting charged particle. Here we present an analysis that uses, for the first time, an indirect detection strategy for EeV neutrinos. We focus on tau neutrinos that have traversed Earth, and show that they reach the IceCube detector, unabsorbed, at energies greater than 100 TeV for most trajectories. This opens up the search for ultra-high energy neutrinos to the entire sky. We use ten years of IceCube data to perform an analysis that looks for secondary neutrinos in the northern sky, and highlight the promise such a strategy can have in the next generation of experiments when combined with direct detection techniques
