Building the qualification and a skill development program within the ENEN-III European Project

The ENEN III project covers the structuring, organization, coordination and implementation of training schemes in cooperation with local, national and international training organizations, to provide training to professionals active in nuclear organizations or their contractors and sub-contractors. The training schemes provide a portfolio of courses, training sessions, seminars, and workshops for continuous learning for upgrading knowledge and developing skills. The training schemes allow individuals to acquire qualifications and skills, as required by the specific positions in the nuclear sector which will be documented in a training passport. The essence of such passport is to be recognized within the EU by the whole nuclear sector which provides mobility to the individual looking for employment and an EU wide recruitment field for the nuclear employers.

Diseño de una red multinivel de conocimiento certificado y su aplicación a la enseñanza universitaria

En la investigación en e-Learning existe un interés especial en la adaptación de los objetos de aprendizaje al estudiante, que se puede realizar por distintos caminos: considerando el perfil del estudiante, los estilos de aprendizaje, estableciendo rutas de aprendizaje, a través de la tutoría individualizada o utilizando sistemas de recomendación. Aunque se han realizado avances en estas facetas de la adaptación, los enfoques existentes aportan soluciones para un entorno específico, sin que exista una orientación que resuelva la adaptación con una perspectiva más genérica, en el contexto de los objetos de aprendizaje y de la enseñanza. Esta tesis, con la propuesta de una “red multinivel de conocimiento certificado” aborda la adaptación a los perfiles de los estudiantes, asume la reutilización de los objetos de aprendizaje e introduce la certificación de los contenidos, sentando las bases de lo que podría ser una solución global al aprendizaje. La propuesta se basa en reestructurar los contenidos en forma de red, en establecer distintos niveles de detalle para los contenidos de cada nodo de la red, para facilitar la adaptación a los conocimientos previos del estudiante, y en certificar los contenidos con expertos. La “red multinivel” se implementa en una asignatura universitaria de grado, integrándola en los apuntes, y se aplica a la enseñanza. La validación de la propuesta se realiza desde cuatro perspectivas: en las dos primeras, se realiza un análisis estadístico para calcular la tasa de aceptación y se aplica un modelo TAM, extrayendo los datos para realizar el análisis de una encuesta que cumplimentan los alumnos; en las otras dos, se analizan las calificaciones académicas y las encuestas de opinión sobre la docencia. Se obtiene una tasa de aceptación del 81% y se confirman el 90% de las hipótesis del modelo TAM, se mejoran las calificaciones en un 21% y las encuestas de opinión en un 9%, lo que valida la propuesta y su aplicación a la enseñanza. ABSTRACT E-Learning research holds a special interest in the adaptation of learning objects to the student, which can be performed in different ways: taking into account the student profile or learning styles, by establishing learning paths, through individualized tutoring or using recommender systems. Although progress has been made in these types of adaptation, existing approaches provide solutions for a specific environment without an approach that addresses the adaptation from a more general perspective, that is, in the context of learning objects and teaching. This thesis, with the proposal of a “certified knowledge multilevel network”, focuses on adapting to the student profile, it is based on the reuse of learning objects and introduces the certification of the contents, laying the foundations for what could be a global solution to learning. The proposal is based on restructuring the contents on a network setting different levels of depth in the contents of each node of the network to facilitate adaptation to the student’s background, and certify the contents with experts. The multilevel network is implemented in a university degree course, integrating it into the notes, and applied to teaching. The validation of the proposal is made from four perspectives: the first two, a statistical analysis is performed to calculate the rate of acceptance and the TAM model is applied, extracting data for analysis of a questionnaire-based survey completed by the students; the other two, academic qualifications and surveys about teaching are analyzed. The acceptance rate is 81%, 90% of TAM model assumptions are confirmed, academic qualifications are improved 21% and opinion survey 9%, which validates the proposal and its application to teaching.

Desarrollo de tecnologías de telemanipulación con alto grado de escalado orientadas a la interacción hombre-robot en entornos nucleares

Esta tesis se centra en desarrollo de tecnologías para la interacción hombre-robot en entornos nucleares de fusión. La problemática principal del sector de fusión nuclear radica en las condiciones ambientales tan extremas que hay en el interior del reactor, y la necesidad de que los equipos cumplan requisitos muy restrictivos para poder aguantar esos niveles de radiación, magnetismo, ultravacío, temperatura... Como no es viable la ejecución de tareas directamente por parte de humanos, habrá que utilizar dispositivos de manipulación remota para llevar a cabo los procesos de operación y mantenimiento. En las instalaciones de ITER es obligatorio tener un entorno controlado de extrema seguridad, que necesita de estándares validados. La definición y uso de protocolos es indispensable para regir su buen funcionamiento. Si nos centramos en la telemanipulación con algo grado de escalado, surge la necesidad de definir protocolos para sistemas abiertos que permitan la interacción entre equipos y dispositivos de diversa índole. En este contexto se plantea la definición del Protocolo de Teleoperación que permita la interconexión entre dispositivos maestros y esclavos de distinta tipología, pudiéndose comunicar bilateralmente entre sí y utilizar distintos algoritmos de control según la tarea a desempeñar. Este protocolo y su interconectividad se han puesto a prueba en la Plataforma Abierta de Teleoperación (P.A.T.) que se ha desarrollado e integrado en la ETSII UPM como una herramienta que permita probar, validar y realizar experimentos de telerrobótica. Actualmente, este Protocolo de Teleoperación se ha propuesto a través de AENOR al grupo ISO de Telerobotics como una solución válida al problema existente y se encuentra bajo revisión. Con el diseño de dicho protocolo se ha conseguido enlazar maestro y esclavo, sin embargo con los niveles de radiación tan altos que hay en ITER la electrónica del controlador no puede entrar dentro del tokamak. Por ello se propone que a través de una mínima electrónica convenientemente protegida se puedan multiplexar las señales de control que van a través del cableado umbilical desde el controlador hasta la base del robot. En este ejercicio teórico se demuestra la utilidad y viabilidad de utilizar este tipo de solución para reducir el volumen y peso del cableado umbilical en cifras aproximadas de un 90%, para ello hay que desarrollar una electrónica específica y con certificación RadHard para soportar los enormes niveles de radiación de ITER. Para este manipulador de tipo genérico y con ayuda de la Plataforma Abierta de Teleoperación, se ha desarrollado un algoritmo que mediante un sensor de fuerza/par y una IMU colocados en la muñeca del robot, y convenientemente protegidos ante la radiación, permiten calcular las fuerzas e inercias que produce la carga, esto es necesario para poder transmitirle al operador unas fuerzas escaladas, y que pueda sentir la carga que manipula, y no otras fuerzas que puedan influir en el esclavo remoto, como ocurre con otras técnicas de estimación de fuerzas. Como el blindaje de los sensores no debe ser grande ni pesado, habrá que destinar este tipo de tecnología a las tareas de mantenimiento de las paradas programadas de ITER, que es cuando los niveles de radiación están en sus valores mínimos. Por otro lado para que el operador sienta lo más fielmente posible la fuerza de carga se ha desarrollado una electrónica que mediante el control en corriente de los motores permita realizar un control en fuerza a partir de la caracterización de los motores del maestro. Además para aumentar la percepción del operador se han realizado unos experimentos que demuestran que al aplicar estímulos multimodales (visuales, auditivos y hápticos) aumenta su inmersión y el rendimiento en la consecución de la tarea puesto que influyen directamente en su capacidad de respuesta. Finalmente, y en referencia a la realimentación visual del operador, en ITER se trabaja con cámaras situadas en localizaciones estratégicas, si bien el humano cuando manipula objetos hace uso de su visión binocular cambiando constantemente el punto de vista adecuándose a las necesidades visuales de cada momento durante el desarrollo de la tarea. Por ello, se ha realizado una reconstrucción tridimensional del espacio de la tarea a partir de una cámara-sensor RGB-D, lo cual nos permite obtener un punto de vista binocular virtual móvil a partir de una cámara situada en un punto fijo que se puede proyectar en un dispositivo de visualización 3D para que el operador pueda variar el punto de vista estereoscópico según sus preferencias. La correcta integración de estas tecnologías para la interacción hombre-robot en la P.A.T. ha permitido validar mediante pruebas y experimentos para verificar su utilidad en la aplicación práctica de la telemanipulación con alto grado de escalado en entornos nucleares de fusión. Abstract This thesis focuses on developing technologies for human-robot interaction in nuclear fusion environments. The main problem of nuclear fusion sector resides in such extreme environmental conditions existing in the hot-cell, leading to very restrictive requirements for equipment in order to deal with these high levels of radiation, magnetism, ultravacuum, temperature... Since it is not feasible to carry out tasks directly by humans, we must use remote handling devices for accomplishing operation and maintenance processes. In ITER facilities it is mandatory to have a controlled environment of extreme safety and security with validated standards. The definition and use of protocols is essential to govern its operation. Focusing on Remote Handling with some degree of escalation, protocols must be defined for open systems to allow interaction among different kind of equipment and several multifunctional devices. In this context, a Teleoperation Protocol definition enables interconnection between master and slave devices from different typologies, being able to communicate bilaterally one each other and using different control algorithms depending on the task to perform. This protocol and its interconnectivity have been tested in the Teleoperation Open Platform (T.O.P.) that has been developed and integrated in the ETSII UPM as a tool to test, validate and conduct experiments in Telerobotics. Currently, this protocol has been proposed for Teleoperation through AENOR to the ISO Telerobotics group as a valid solution to the existing problem, and it is under review. Master and slave connection has been achieved with this protocol design, however with such high radiation levels in ITER, the controller electronics cannot enter inside the tokamak. Therefore it is proposed a multiplexed electronic board, that through suitable and RadHard protection processes, to transmit control signals through an umbilical cable from the controller to the robot base. In this theoretical exercise the utility and feasibility of using this type of solution reduce the volume and weight of the umbilical wiring approximate 90% less, although it is necessary to develop specific electronic hardware and validate in RadHard qualifications in order to handle huge levels of ITER radiation. Using generic manipulators does not allow to implement regular sensors for force feedback in ITER conditions. In this line of research, an algorithm to calculate the forces and inertia produced by the load has been developed using a force/torque sensor and IMU, both conveniently protected against radiation and placed on the robot wrist. Scaled forces should be transmitted to the operator, feeling load forces but not other undesirable forces in slave system as those resulting from other force estimation techniques. Since shielding of the sensors should not be large and heavy, it will be necessary to allocate this type of technology for programmed maintenance periods of ITER, when radiation levels are at their lowest levels. Moreover, the operator perception needs to feel load forces as accurate as possible, so some current control electronics were developed to perform a force control of master joint motors going through a correct motor characterization. In addition to increase the perception of the operator, some experiments were conducted to demonstrate applying multimodal stimuli (visual, auditory and haptic) increases immersion and performance in achieving the task since it is directly correlated with response time. Finally, referring to the visual feedback to the operator in ITER, it is usual to work with 2D cameras in strategic locations, while humans use binocular vision in direct object manipulation, constantly changing the point of view adapting it to the visual needs for performing manipulation during task procedures. In this line a three-dimensional reconstruction of non-structured scenarios has been developed using RGB-D sensor instead of cameras in the remote environment. Thus a mobile virtual binocular point of view could be generated from a camera at a fixed point, projecting stereoscopic images in 3D display device according to operator preferences. The successful integration of these technologies for human-robot interaction in the T.O.P., and validating them through tests and experiments, verify its usefulness in practical application of high scaling remote handling at nuclear fusion environments.

Estudio empírico de la influencia de la experiencia y del conocimiento del dominio del analista en la efectividad de la educción de requisitos

Contexto: La presente tesis doctoral se enmarca en la actividad de educción de los requisitos. La educción de requisitos es generalmente aceptada como una de las actividades más importantes dentro del proceso de Ingeniería de Requisitos, y tiene un impacto directo en la calidad del software. Es una actividad donde la comunicación entre los involucrados (analistas, clientes, usuarios) es primordial. La efectividad y eficacia del analista en la compresión de las necesidades de clientes y usuarios es un factor crítico para el éxito del desarrollo de software. La literatura se ha centrado principalmente en estudiar y comprender un conjunto específico de capacidades o habilidades personales que debe poseer el analista para realizar de forma efectiva la actividad de educción. Sin embargo, existen muy pocos trabajos que han estudiado dichas capacidades o habilidades empíricamente. Objetivo: La presente investigación tiene por objetivo estudiar el efecto de la experiencia, el conocimiento acerca del dominio y la titulación académica que poseen los analistas en la efectividad del proceso de educción de los requisitos, durante los primeros contactos del analista con el cliente. Método de Investigación: Hemos ejecutado 8 estudios empíricos entre cuasi-experimentos (4) y experimentos controlados (4). Un total de 110 sujetos experimentales han participado en los estudios, entre estudiantes de post-grado de la Escuela Técnica Superior de Ingenieros Informáticos de la Universidad Politécnica de Madrid y profesionales. La tarea experimental consistió en realizar sesiones de educción de requisitos sobre uno o más dominios de problemas (de carácter conocido y desconocido para los sujetos). Las sesiones de educción se realizaron empleando la entrevista abierta. Finalizada la entrevista, los sujetos reportaron por escrito toda la información adquirida. Resultados: Para dominios desconocidos, la experiencia (entrevistas, requisitos, desarrollo y profesional) del analista no influye en su efectividad. En dominios conocidos, la experiencia en entrevistas (r = 0.34, p-valor = 0.080) y la experiencia en requisitos (r = 0.22, p-valor = 0.279), ejercen un efecto positivo. Esto es, los analistas con más años de experiencia en entrevistas y/o requisitos tienden a alcanzar mejores efectividades. Por el contrario, la experiencia en desarrollo (r = -0.06, p-valor = 0.765) y la experiencia profesional (r = -0.35, p-valor = 0.077), tienden a ejercer un efecto nulo y negativo, respectivamente. En lo que respecta al conocimiento acerca del dominio del problema que poseen los analistas, ejerce un moderado efecto positivo (r=0.31), estadísticamente significativo (p-valor = 0.029) en la efectividad de la actividad de educción. Esto es, los analistas con conocimiento tienden a ser más efectivos en los dominios de problema conocidos. En lo que respecta a la titulación académica, por falta de diversidad en las titulaciones académicas de los sujetos experimentales no es posible alcanzar una conclusión. Hemos podido explorar el efecto de la titulación académica en sólo dos cuasi-experimentos, sin embargo, nuestros resultados arrojan efectos contradictorios (r = 0.694, p-valor = 0.51 y r = -0.266, p-valor = 0.383). Además de las variables estudiadas indicadas anteriormente, hemos confirmado la existencia de variables moderadoras que afectan a la actividad de educción, tales como el entrevistado o la formación. Nuestros datos experimentales confirman que el entrevistado es un factor clave en la actividad de educción. Estadísticamente ejerce una influencia significativa en la efectividad de los analistas (p-valor= 0.000). La diferencia entre entrevistar a uno u otro entrevistado, en unidades naturales, varía entre un 18% - 23% en efectividad. Por otro lado, la formación en requisitos aumenta considerablemente la efectividad de los analistas. Los sujetos que realizaron la educción de requisitos después de recibir una formación específica en requisitos tienden a ser entre un 12% y 20% más efectivos que aquellos que no la recibieron. El efecto es significativo (p-valor = 0.000). Finalmente, hemos observado tres hechos que podrían influir en los resultados de esta investigación. En primer lugar, la efectividad de los analistas es diferencial dependiendo del tipo de elemento del dominio. En dominios conocidos, los analistas con experiencia tienden a adquirir más conceptos que los analistas noveles. En los dominios desconocidos, son los procesos los que se adquieren de forma prominente. En segundo lugar, los analistas llegan a una especie de “techo de cristal” que no les permite adquirir más información. Es decir, el analista sólo reconoce (parte de) los elementos del dominio del problema mencionado. Este hecho se observa tanto en el dominio de problema desconocido como en el conocido, y parece estar relacionado con el modo en que los analistas exploran el dominio del problema. En tercer lugar, aunque los años de experiencia no parecen predecir cuán efectivo será un analista, sí parecen asegurar que un analista con cierta experiencia, en general, tendrá una efectividad mínima que será superior a la efectividad mínima de los analistas con menos experiencia. Conclusiones: Los resultados obtenidos muestran que en dominios desconocidos, la experiencia por sí misma no determina la efectividad de los analistas de requisitos. En dominios conocidos, la efectividad de los analistas se ve influenciada por su experiencia en entrevistas y requisitos, aunque sólo parcialmente. Otras variables influyen en la efectividad de los analistas, como podrían ser las habilidades débiles. El conocimiento del dominio del problema por parte del analista ejerce un efecto positivo en la efectividad de los analistas, e interacciona positivamente con la experiencia incrementando aún más la efectividad de los analistas. Si bien no fue posible obtener conclusiones sólidas respecto al efecto de la titulación académica, si parece claro que la formación específica en requisitos ejerce una importante influencia positiva en la efectividad de los analistas. Finalmente, el analista no es el único factor relevante en la actividad de educción. Los clientes/usuarios (entrevistados) también juegan un rol importante en el proceso de generación de información. ABSTRACT Context: This PhD dissertation addresses requirements elicitation activity. Requirements elicitation is generally acknowledged as one of the most important activities of the requirements process, having a direct impact in the software quality. It is an activity where the communication among stakeholders (analysts, customers, users) is paramount. The analyst’s ability to effectively understand customers/users’ needs represents a critical factor for the success of software development. The literature has focused on studying and comprehending a specific set of personal skills that the analyst must have to perform requirements elicitation effectively. However, few studies have explored those skills from an empirical viewpoint. Goal: This research aims to study the effects of experience, domain knowledge and academic qualifications on the analysts’ effectiveness when performing requirements elicitation, during the first stages of analyst-customer interaction. Research method: We have conducted eight empirical studies, quasi-experiments (four) and controlled experiments (four). 110 experimental subjects participated, including: graduate students with the Escuela Técnica Superior de Ingenieros Informáticos of the Universidad Politécnica de Madrid, as well as researchers and professionals. The experimental tasks consisted in elicitation sessions about one or several problem domains (ignorant and/or aware for the subjects). Elicitation sessions were conducted using unstructured interviews. After each interview, the subjects reported in written all collected information. Results: In ignorant domains, the analyst’s experience (interviews, requirements, development and professional) does not influence her effectiveness. In aware domains, interviewing experience (r = 0.34, p-value = 0.080) and requirements experience (r = 0.22, p-value = 0.279), make a positive effect, i.e.: the analysts with more years of interviewing/requirements experience tend to achieve higher effectiveness. On the other hand, development experience (r = -0.06, p-value = 0.765) and professional experience (r = -0.35, p-value = 0.077) tend to make a null and negative effect, respectively. On what regards the analyst’s problem domain knowledge, it makes a modest positive effect (r=0.31), statistically significant (p-value = 0.029) on the effectiveness of the elicitation activity, i.e.: the analysts with tend to be more effective in problem domains they are aware of. On what regards academic qualification, due to the lack of diversity in the subjects’ academic degrees, we cannot come to a conclusion. We have been able to explore the effect of academic qualifications in two experiments; however, our results show opposed effects (r = 0.694, p-value = 0.51 y r = -0.266, p-value = 0.383). Besides the variables mentioned above, we have confirmed the existence of moderator variables influencing the elicitation activity, such as the interviewee and the training. Our data confirm that the interviewee is a key factor in the elicitation activity; it makes statistically significant effect on analysts’ effectiveness (p-value = 0.000). Interviewing one or another interviewee represents a difference in effectiveness of 18% - 23%, in natural units. On the other hand, requirements training increases to a large extent the analysts’ effectiveness. Those subjects who performed requirements elicitation after specific training tend to be 12% - 20% more effective than those who did not receive training. The effect is statistically significant (p-value = 0.000). Finally, we have observed three phenomena that could have an influence on the results of this research. First, the analysts’ effectiveness differs depending on domain element types. In aware domains, experienced analysts tend to capture more concepts than novices. In ignorant domains, processes are identified more frequently. Second, analysts get to a “glass ceiling” that prevents them to acquire more information, i.e.: analysts only identify (part of) the elements of the problem domain. This fact can be observed in both the ignorant and aware domains. Third, experience years do not look like a good predictor of how effective an analyst will be; however, they seem to guarantee that an analyst with some experience years will have a higher minimum effectiveness than the minimum effectiveness of analysts with fewer experience years. Conclusions: Our results point out that experience alone does not explain analysts’ effectiveness in ignorant domains. In aware domains, analysts’ effectiveness is influenced the experience in interviews and requirements, albeit partially. Other variables influence analysts’ effectiveness, e.g.: soft skills. The analysts’ problem domain knowledge makes a positive effect in analysts’ effectiveness; it positively interacts with the experience, increasing even further analysts’ effectiveness. Although we could not obtain solid conclusions on the effect of the academic qualifications, it is plain clear that specific requirements training makes a rather positive effect on analysts’ effectiveness. Finally, the analyst is not the only relevant factor in the elicitation activity. The customers/users (interviewees) play also an important role in the information generation process.

A QUALIFICAÇÃO E A INSERÇÃO NO MUNDO DO TRABALHO DA PESSOA PORTADORA DE DEFICIÊNCIA: UM ESTUDO SOBRE O IMPACTO DA EXTINÇÃO DA LEI 6.297/75

O presente estudo tem como objetivo, analisar sobre as dificuldades enfrentadas tanto pelas Empresas em cumprir a Legislação de Cotas, como também da Pessoa Portadora de Deficiência (PPDs) em ser inserida no mercado de trabalho, devido a falta de qualificação dos candidatos. Através da pesquisa literária ficou claro que nossa Legislação demonstra de forma evidente que o legislador pretendeu assegurar aos PPDs, as condições mínimas de participação influente na vida ativa da sociedade brasileira e num avanço sem precedentes, criaram-se as linhas básicas do processo de integração do deficiente à sociedade e ao mercado produtivo nacional. Verificou-se também que as empresas estão em busca de profissionais dentre o universo dos PPDs, já qualificados, o que normalmente não encontram. As Organizações do Direito Privado também já desenvolveram alguns projetos para a qualificação desses PPDs. A Lei 6.297/75 que garantia às empresas o desconto em dobro no IR dos gastos com treinamento, foi extinta em 12 de Dezembro de 1990. As empresas precisam de um incentivo financeiro para que possam tratar da qualificação desses profissionais, não mais como um peso, mas sim como um projeto social. Caso as empresas fossem beneficiadas por incentivos fiscais, assim como eram na vigência dessa Lei, teriam as empresas uma visão diferenciada por ocasião da contratação dos PPDs? A metodologia de pesquisa prevê um levantamento bibliográfico e uma pesquisa exploratória que será feita em empresas privadas, instituições que visam ajudar na inserção dos PPDs e nas Organizações do Direito Privado tais como Senai, Sesi, Força Sindical, Fiesp. Verificou-se, mediante a pesquisa, que há uma preocupação por parte de todos os envolvidos, em encontrar meios eficazes para garantir a inserção dos PPDs no mercado de trabalho, embora a falta de qualificação ainda seja o maior problema. A criação de Leis similares à Lei 6.297/75 foi apontada como uma grande ajuda às empresas, já que a elas foi imposta essa responsabilidade.(AU)

Comunicação social com software livre

A tecnologização que a sociedade experimenta nas últimas décadas trouxe a profusão de máquinas informatizadas e seus sistemas de operação. Neste período a indústria desenvolveu sofisticados e caros softwares aplicativos proprietários para o pleno uso destas máquinas, o que colocou boa parte do mercado social nas mãos de poucas empresas multinacionais, entre elas, a Microsoft, e outras. Mas, o espírito libertário de membros das comunidades científicas e hackers promoveu o desenvolvimento do software livre e aberto, que pode ser usado como bem social mais amplo e, principalmente, evoluir no melhor do espírito colaborativo. O presente trabalho estuda os dois modelos de produção de software, os compara visando tornar evidentes as qualidades de cada um, seus custos, rendimentos e possibilidades de adoção. Projeta a possibilidade de que as habilitações da área da comunicação possam migrar para o modelo de software livre, dadas as plenas qualidades deste sistema, a radical redução de custos e as constatações que amplos segmentos da produção audiovisual os está adotando. Para tanto, compara as experiências aplicadas com ambos os sistemas em dois cursos de comunicação, em sua habilitação de Rádio e Televisão.(AU)

What makes an ad enjoyable? Analysing advertising appeals as viewed by Portuguese consumers

Nowadays, consumers are faced with a variety of media that convey myriad advertising messages, which struggle amidst a highly competitive environment, with a view to drawing the viewers’ attention, raising awareness, creating interest and inspiring desire and, ultimately, leading to the purchase of the product/service at stake. For this, advertising professionals deliberately intertwine their selling arguments with emotionally-charged creative concepts. It is the aim of this study to analyse the impact of the main creative appeals and to identify groups of consumers based on their attitudes towards them. We have undertaken a quantitative study, by means of a survey administered to a convenience sample with a list of creative appeals, which had to be classified by the respondents according to their attitudes. Globally speaking, the preferred appeals were humour, music and animation. Nonetheless, it was possible to divide the respondents into three groups. ‘Advertising fans’, the ‘rationally-minded’ and the ‘emotionally-minded’. This study presents some limitations, especially as to the sample used. Apart from the reduced number of respondents and lack of more widespread geographic reach, some academic qualifications were underrepresented. The results of this study offer some avenues to be explored by marketing and advertising professionals when it comes to deciding on the best creative approach to select for their advertising campaigns. Besides, this study paves the way to the development of future research on the issue of advertising appeals and its relationship with the psychographic characteristics of consumers.

Capital humano y turismo: rendimiento educativo, desajuste y satisfacción laboral

El capital humano es un elemento clave para el logro de objetivos en términos de competitividad y crecimiento del sector de turismo en España. En este trabajo se utilizan datos muy recientes (procedentes de la Encuesta de Calidad de Vida en el Trabajo, ECVT) para abordar tres aspectos fundamentales en su análisis: el rendimiento educativo que los trabajadores obtienen a cambio de la inversión que realizan en su formación reglada; la medición de los niveles de desajuste entre dicha formación y los puestos de trabajo que ocupan, y su relación con el salario; y, por último, el análisis de diversas dimensiones de la satisfacción laboral y de la relación que se establece entre ellas y la sobre-educación de los trabajadores.

Individual returns to education in the Spanish tourism sector during the economic crisis

This paper analyses individual returns to education in the Spanish tourism sector. The results, which are robust to different specifications of Mincer earnings regressions, show that the earnings returns to schooling for tourism workers are only half those for all other sectors, and that the difference in returns between these two groups has increased significantly during the economic crisis. This has happened at a time when the earnings range between those with lower and higher qualifications has narrowed in tourism while it has remained stable in other sectors, and when tourism has been capable of retaining most of its workforce while the rest of the economy has experienced a sharp decrease in employment.

Impact of the Decarbonisation of the Energy System on Employment in Europe. CEPS Special Report No. 82, February 2014

This paper presents a methodology for calculating the potential impact of the new socio-ecological transition away from fossil fuels on employment in EU energy supply. The methodology is based on “employment factors” (i.e. labour intensities) of different energy technologies. These employment factors are applied to changing energy mixes as projected by the decarbonisation scenarios of the European Commission’s Energy Roadmap 2050. In particular, we analyse quantitative (number of jobs) and qualitative (qualification levels) impacts on employment in extraction and processing of primary (fossil) fuels and in the power sector for the years 2020, 2030 and 2050. The results show that the energy sector will provide not only more jobs as the new socio-ecological transition unfolds, but also jobs requiring higher-level qualifications when compared with the current energy sector.

Making the Most of EU Labour Mobility. Report of a CEPS Task Force in Cooperation with the Bertelsmann Foundation. CEPS Task Force Report, 7 October 2014

This Task Force report combines the most recent data from Eurostat with national sources to highlight the most significant labour mobility trends within the EU. Overall, the recent recession has not induced previously immobile workers to become more mobile, at least not in the larger member states. Mobility flows have moved away from crisis countries in response to the economic downturn but the desired increase in south-north mobility has not been observed so far. This leads the authors to conclude that successfully fostering mobility within EU15 countries requires tremendous effort. It is important that workers who are willing and able to move are not discouraged from doing so by unnecessary barriers to mobility. Improving the workings of the EURES system and its online job-matching platform; better cooperation of national employment agencies; streamlining the recognition of qualifications; and supporting language training within the EU are important contributions to labour mobility. The authors conclude that the EU is right to defend the free movement of workers. National governments should keep in mind that their ability to tap into an attractive foreign labour supply also hinges upon the perception of how mobile workers are treated in destination countries. If the political imperative requires regulations to be changed, such as the one guiding the coordination of social security, it is essential that no new mobility barriers are put in place.

Rethinking the Attractiveness of EU Labour Immigration Policies: Comparative perspectives on the EU, the US, Canada and beyond

Is Europe's immigration policy attractive? One of the priorities driving current EU debates on labour immigration policies is the perceived need to boost Europe's attractiveness vis-á-vis 'talented' and 'highly skilled' immigrants. The EU sees itself playing a role in persuading immigrants to choose Europe over other competing destinations, such as the US or Canada. This book critically examines the determinants and challenges characterising discussions focused on the attractiveness of labour migration policies in the EU as well as other international settings. It calls for re-thinking some of the most commonly held premises and assumptions underlying the narratives of ‘attractiveness’ and ‘global competition for talent’ in migration policy debates. How can an immigration policy, in fact, be made to be ‘attractive’ and what are the incentives at play (if any)? A multidisciplinary team of leading scholars and experts in migration studies address the main issues and challenges related to the role played by rights and discrimination, qualifications and skills, and matching demand and supply in needs-based migration policies. The experiences in other jurisdictions such as South America, Canada and the United States are also covered: Are these countries indeed so ‘attractive’ and ‘competitive’, and if so what makes them more attractive than the EU? On the basis of the discussions and findings presented across the various contributions, the book identifies a number of priorities for policy formulation and design in the next generation of EU labour migration policies.

Economic Approaches of the Internal Market. Bruges European Economic Research (BEER) Papers 13/April 2008

What is ‘the’ EU internal market, as economists see it? The present BEER paper attempts to survey and help readers understand various ‘economic’ approaches to the internal market idea. The paper starts with a conceptual discussion of what ‘the’ internal market is (in an economic perspective). Six different economic meanings of the internal market are presented, with the sixth one being the economic benchmark in an ideal setting. Subsequently, the question is asked what the internal market (i.e. its proper functioning) is good for. Put differently, the internal market in the EU Treaty is a means, but a means to what? Beyond the typical economic growth objectives of the Rome Treaty (still valid today, with some qualifications), other Treaty objectives have emerged. Economists typically think in means-end relationships and the instrumental role of the internal market for Treaty objectives is far from clear. The ‘new’ Commission internal market strategy of 2007 proposes a more goal-oriented internal market policy. Such a vision is more selective in picking intermediate objectives to which ‘the’ internal market should be instrumental, but it risks to ignore the major deficits in today’s internal market: services and labour! The means-end relationships get even more problematic once one begins to scrutinise all the socio-economic objectives of the current (Amsterdam/Nice) Treaty or still other intermediate objectives. The internal market (explicitly including the relevant common regulation) then becomes a ‘jack of all trades’ for the environment, a high level of social protection, innovation or ‘Social Europe’. These means/ends relationships often are ill-specified. The final section considers the future of the internal market, by distinguishing three strategies: incremental strategies (including the new internal market strategy of November 2007); the internal market as the core of the Economic Union serving the ‘proper functioning of the monetary union’; and deepening and widening of the internal market as justified by the functional subsidiarity test. Even though the latter two would seem to be preferable from an economic point of view, they currently lack political legitimacy and are therefore unlikely to be pursued in the near future.

Labour Mobility in Europe: An untapped resource? CEPS Policy Brief No. 327, March 2015

Despite public perceptions, labour mobility is low in the EU, particularly within the euro area. The authors of this Policy Brief make four main points: first, that the economic and financial crisis has affected mobility patterns by redirecting flows away from the periphery, thus showing the limits of labour mobility potential within the current eurozone - largely due to the negligible mobility of nationals from large countries hit by the crisis. Second, east-west mobility has not been fundamentally affected by the crisis, and ten years after the eastern enlargement the number of East Europeans living in EU15 should be of no overall concern. Third, the long-term economic effects of mobility are uncertain, but potential negative effects are more likely to show up in sending countries than in receiving ones. Finally, in view of the lessons learned from the economic crisis, the Commission and member states should adopt a longer-term view on labour mobility. The authors recommend a further upgrade of job-matching tools, namely the EURES system, and should foster better recognition of qualifications and the exchange of best practices among mobility networks. In order to improve mobility in the longer term, the Commission and member states should improve the mobility of third-country nationals – starting with those completing tertiary education at an EU institution and able to find employment. The aim of improving mobility gives new impetus to the ‘mother tongue + two foreign languages’ objective and the European Benchmark of Language Competences Initiative, in particular competence in the first foreign language taught at school.
