Effects of Bologna, the economic crisis and the immigration in enrollment at the UPM

Over the past 20 years, the economic landscape has changed dramatically in Spain, undergoing a growth explosion and a subsequent decline which has led to the current economic crisis. This growth has led to heavy immigration from both developed and developing countries, which provided skilled and unskilled labour. This article aims to analyze the impact of immigrant students at the Polytechnic University of Madrid, pondering the effect that the economic crisis is having and will have on this group, and evaluating the implementation of new plans of Bologna. We analyze the enrolment at the UPM and particularize to the Civil Engineering school (previous EUITOP), crossing with the effect of the economic crisis on foreign students. The exponential increase of foreign students, most of them from Latin American and born in Spain, and students of European countries that have started to register considerably from 2002 and 2003, lead us to consider a renewal in certain areas of learning, and to exploit the possibility of interaction with other countries so successful through the acquisition of transversal skills, as well as to guide and improve, support and integrate these groups at our university Keywords: knowledge, learning, Bologna, academic record

A robustness verification system for mobile phone authentication based on gestures using Linear Discriminant Analysis

This article evaluates an authentication technique for mobiles based on gestures. Users create a remindful identifying gesture to be considered as their in-air signature. This work analyzes a database of 120 gestures of different vulnerability, obtaining an Equal Error Rate (EER) of 9.19% when robustness of gestures is not verified. Most of the errors in this EER come from very simple and easily forgeable gestures that should be discarded at enrollment phase. Therefore, an in-air signature robustness verification system using Linear Discriminant Analysis is proposed to infer automatically whether the gesture is secure or not. Different configurations have been tested obtaining a lowest EER of 4.01% when 45.02% of gestures were discarded, and an optimal compromise of EER of 4.82% when 19.19% of gestures were automatically rejected.

Foreigner? Want to study in Spain? The integration process at universities

The student exchange programs being carried out at universities for over 50 years, have led to changes in the institutions, which had to adapt to accommodate these students. Despite those changes, the integration of foreign students not coming from the aforementioned exchange programs that come to our country to study at the University has been neglected. These students face many barriers (language, cultural and origin customs mainly), so a clear and detailed information would be highly desirable in order to facilitate the necessary arrangements This study aims to show the deficiencies in the integration process and hosting programs faced by a foreign student at University. The study is performed by means of an analysis of statistical data from the Polytechnic University of Madrid and the Civil Engineering School over the last 12 school years (1999 - 2000 to 2010 - 2011), as well as surveys and interviews with some of these students. The study is enhanced with the analysis of the measures and integration methods of the various minorities, which had been implemented by the foremost public universities in Spain, as well as other public and private universities abroad. It illustrates the existing backlog at the Spanish universities with regards to supporting the integration of diversity among foreign students, providing data concerning the growth of such population and its impact at the university, and on the institutions in particular. In an increasingly globalized world, we must understand and facilitate the integration of minorities at University, supplying them, from the first day, and before the enrollment process, the essential elements that will allow their adequate adaptation to the educational process at University. It concludes by identifying the main subjects that need to be tackled to endorse such integration.

The University in the Cloud Computing.

With the advancement of Information and Communication Technology ICT which favors increasingly fast, easy, and accessible communication for all and which can reach large groups of people, there have been changes, in recent years in our society that have modified the way we interact, communicate and transmit information. Access to this, it is possible, not only through computers situated in a fixed location, but new mobile devices make it available, wherever the user happens to be located. Now, information "travels" with the user. These forms of communication, transmission and access to information, have also affected the way to conceive and manage business. To these new forms of business that the Internet has brought, is now added the concept of companies in the Cloud Computing ClC. The ClC technology is based on the supply and consumption of services on demand and pay per use, and it gives a 180 degree turn to the business management concept. Small and large businesses may use the latest developments in ICT, to manage their organizations without the need for expensive investments in them. This will enable enterprises to focus more specifically within the scope of their business, leaving the ICT control to the experts. We believe that education can also and should benefit from these new philosophies. ?Due to the global economic crisis in general and each country in particular, economic cutbacks have come to most universities. These are seen in the need to raise tuition rates, which makes increasingly fewer students have the opportunity to pursue higher education?. In this paper we propose using ClC technologies in universities and we make a dissertation on the advantages that it can provide to both: universities and students. For the universities, we expose two focuses, one: ?to reorganize university ICT structures with the ClC philosophy? and the other one, ?to extend the offer of the university education with education on demand?. Regarding the former we propose to use public or private Clouds, to reuse resources across the education community, to save costs on infrastructure investment, in upgrades and in maintenance of ICT, and paying only for what you use and with the ability to scale according to needs. Regarding the latter, we propose an educational model in the ClC, to increase the current university offerings, using educational units in the form of low-cost services and where students pay only for the units consumed on demand. For the students, they could study at any university in the world (virtually), from anywhere, without travel costs: money and time, and what is most important paying only for what they consume. We think that this proposal of education on demand may represent a great change in the current educational model, because strict registration deadlines disappear, and also the problem of economically disadvantaged students, who will not have to raise large amounts of money for an annual tuition. Also it will decrease the problem of loss of the money invested in an enrollment when the student dropout. In summary we think that this proposal is interesting for both, universities and students, we aim for "Higher education from anywhere, with access from any mobile device, at any time, without requiring large investments for students, and with reuse and optimization of resources by universities. Cost by consumption and consumption by service?. We argue for a Universal University "wisdom and knowledge accessible to all?

Analysis of the traded volume drivers of the Iberian power futures market

A comprehensive assessment of the liquidity development in the Iberian power futures market managed by OMIP (“Operador do Mercado Ibérico de Energia, Pólo Português”) in its first 4 years of existence is performed. This market started on July 2006. A regression model tracking the evolution of the traded volumes in the continuous market is built as a function of 12 potential liquidity drivers. The only significant drivers are the traded volumes in OMIP compulsory auctions, the traded volumes in the “Over The Counter” (OTC) market, and the OTC cleared volumes in OMIP clearing house (OMIClear). Furthermore, the enrollment of financial members shows strong correlation with the traded volumes in the continuous market. OMIP liquidity is still far from the levels reached by the most mature European markets (Nord Pool and EEX). The market operator and its clearing house could develop efficient marketing actions to attract new entrants active in the spot market (energy intensive industries, suppliers, and small producers) as well as volumes from the opaque OTC market, and to improve the performance of existing illiquid products. An active dialogue with all the stakeholders (market participants, spot market operator, and supervisory authorities) will help to implement such actions.

Estudio y desarrollo de un cliente SCEP en una PKI corporativa

El presente proyecto propone la utilización de un protocolo de obtención y gestión de certificados llamado SCEP (Simple Certificate Enrollment Protocol), utilizado inicialmente para el aprovisionamiento automático de certificados en routers y switches de la marca Cisco Networks, para su uso en dispositivos personales o corporativos dentro del ámbito laboral. En la actualidad, se están aplicando nuevas técnicas más eficientes de control del uso de los dispositivos corporativos por parte de los empleados de determinadas empresas. Estas empresas son las encargadas de proporcionar a sus empleados dichos dispositivos, que en muchos casos son un ordenador personal y un teléfono móvil. En las empresas del sector de las TIC, el uso de esos dispositivos es la principal herramienta de sus empleados, con lo que la seguridad y control son mecanismos fundamentales que deben estar presentes y garantizados. Además, nuevas tendencias como el BYOD (Bring Your Own Device o el teletrabajo, permiten a los empleados tanto el uso de los dispositivos corporativos lejos del ámbito laboral (en su domicilio, por ejemplo), como el uso de dispositivos no preparados de antemano por la empresa. A priori, estas técnicas suponen un avance en comodidad para los empleados; pero puede significar todo lo contrario cuando se habla del mantenimiento de la seguridad y el control de acceso a los recursos de la empresa desde dichos dispositivos (obtención de certificados para acceder a recursos internos, envío de información cifrada entre individuos de la misma empresa, etc). Es aquí donde cobra sentido la idea de utilizar un protocolo de aprovisionamiento y gestión automatizada de certificados para garantizar la seguridad y control de acceso en la PKI (Public Key Infrastructure) corporativa, permitiendo el uso de dispositivos personales, y evitando la acumulación de trámites burocráticos incómodos tanto para el empleado como para la empresa. Este proyecto plantea la utilización del protocolo SCEP como mecanismo para la realización de la gestión automatizada de certificados ampliando su utilización a dispositivos de escritorio Windows y móviles Android.

La evaluación de la competencia comunicativa específica en el ámbito de la ingeniería y la arquitectura

La progresiva internacionalización de las universidades españolas convierte a estas organizaciones en escenarios plurilingües. El español convive en ellos con otras lenguas, en especial el inglés, como vehículo de acceso y transmisión de conocimiento especializado. Esto requiere un proceso de alfabetización académica en lengua extranjera que tendrían que asumir las universidades de acogida, con objeto de preservar a los alumnos de los fracasos en los programas internacionales. Por el momento, en España, los programas de grado o de posgrado no establecen filtros con umbrales lingüísticos mínimos de acceso, a excepción de algunas universidades que se limitan a requerir certificados de grado de dominio del español general. No existen exámenes públicos de ingreso, o exámenes propios de postadmisión, que evalúen la habilidad lingüística comunicativa en contextos académicos. En este trabajo, se parte de la hipótesis de que los exámenes que certifican un grado de dominio de español general no sirven al propósito de discriminar a los alumnos capaces de seguir con éxito los programas de las universidades. Para verificarla, se desarrolla una prueba de examen específica que mida la capacidad de emplear el español en contextos académicos. La prueba se centra en las tareas que se revelan, en una primera fase exploratoria de la investigación, como más necesarias en lo que se refiere al uso del español como lengua vehicular: las clases magistrales. Una vez pilotada, se administró junto con otras destinadas a evaluar el grado de dominio de la lengua en contextos generales. Los resultados obtenidos del contraste de estas mediciones y de diversos análisis de los datos arrojan evidencias de que este tipo de prueba mide un constructo específico: la habilidad de uso del español en contextos académicos. ABSTRACT The progressive internationalization of Spanish universities has transformed these organizations into plurilingual scenarios. Spanish lives in them sharing the stage with other languages, especially English, as a means of access and transmission of expert knowledge. This requires a process of academic literacy in foreign language that host universities should assume, in order to safeguard students from failures in international programs. At the moment, in Spain, undergraduate or graduate programs do not set filters with minimum language requirements to gain access, except for some universities that merely require certificates of general Spanish. There are no Spanish language public admission exams, or post-enrollment tests of their own, to assess the communicative language ability of foreign students in academic contexts. In this dissertation, we start from the hypothesis that those tests that certify the student degree of mastery of the Spanish language do not serve the purpose of discriminating against students capable of successfully pursuing university programs. To prove it, a specific test that measures the ability to use Spanish in academic contexts was developed. This language test focused on the tasks associated with the most common genre, which revealed prominent in a first exploratory phase of the investigation, related to the use of Spanish as a means of instruction: university lectures. Once piloted, the test was administered along with others designed to assess the degree of mastery of the language in general contexts. Contrast results of these measurements and various analyzes of the data showed evidence that this type of test measures a specific construct: the ability to use Spanish in academic contexts.
