Motivation, communication, satisfaction : on apprend car est motivé et on est motivé car on est intéressé. Une fois appris ce que l,on voulait apprendre, on est donc satisfait. 'Motivación, comunicación, satisfacción : se aprende si se está motivado y se está motivado si se tiene interés. Una vez que se aprende, se está satisfecho'.

El aprendizaje no depende exclusivamente de la pericia del profesor. La relación interpersonal entre alumno y profesor, el contexto en el que vive el alumno y la motivación para el aprendizaje influyen bastante. En un curso de lengua extranjera, la primera competencia que se promueve es la comunicación, pero se deben promover otras cualidades como la creatividad, la iniciativa y la motivación. Se analiza la relación entre motivación y satisfacción de los alumnos.

The effect of counterpoise correction and relaxation energy term to the internal rotation barriers: application to the BF3 ...NH3 and C2H4 ...SO2 dimers

The relevance of the fragment relaxation energy term and the effect of the basis set superposition error on the geometry of the BF3⋯NH3 and C2H4⋯SO2 van der Waals dimers have been analyzed. Second-order Møller-Plesset perturbation theory calculations with the d95(d,p) basis set have been used to calculate the counterpoise-corrected barrier height for the internal rotations. These barriers have been obtained by relocating the stationary points on the counterpoise-corrected potential energy surface of the processes involved. The fragment relaxation energy can have a large influence on both the intermolecular parameters and barrier height. The counterpoise correction has proved to be important for these systems

A new all-round density functional based on spin states and SN2 barriers

We report here a new empirical density functional that is constructed based on the performance of OPBE and PBE for spin states and SN 2 reaction barriers and how these are affected by different regions of the reduced gradient expansion. In a previous study [Swart, Sol̀, and Bickelhaupt, J. Comput. Methods Sci. Eng. 9, 69 (2009)] we already reported how, by switching between OPBE and PBE, one could obtain both the good performance of OPBE for spin states and reaction barriers and that of PBE for weak interactions within one and the same (SSB-sw) functional. Here we fine tuned this functional and include a portion of the KT functional and Grimme's dispersion correction to account for π- π stacking. Our new SSB-D functional is found to be a clear improvement and functions very well for biological applications (hydrogen bonding, π -π stacking, spin-state splittings, accuracy of geometries, reaction barriers)

The effects of information and communication technologies on the banking sector and the payments system

This dissertation studies the effects of Information and Communication Technologies (ICT) on the banking sector and the payments system. It provides insight into how technology-induced changes occur, by exploring both the nature and scope of main technology innovations and evidencing their economic implications for banks and payment systems. Some parts in the dissertation are descriptive. They summarise the main technological developments in the field of finance and link them to economic policies. These parts are complemented with sections of the study that focus on assessing the extent of technology application to banking and payment activities. Finally, it includes also some work which borrows from the economic literature on banking. The need for an interdisciplinary approach arises from the complexity of the topic and the rapid path of change to which it is subject. The first chapter provides an overview of the influence of developments in ICT on the evolution of financial services and international capital flows. We include main indicators and discuss innovation in the financial sector, exchange rates and international capital flows. The chapter concludes with impact analysis and policy options regarding the international financial architecture, some monetary policy issues and the role of international institutions. The second chapter is a technology assessment study that focuses on the relationship between technology and money. The application of technology to payments systems is transforming the way we use money and, in some instances, is blurring the definition of what constitutes money. This chapter surveys the developments in electronic forms of payment and their relationship to the banking system. It also analyses the challenges posed by electronic money for regulators and policy makers, and in particular the opportunities created by two simultaneous processes: the Economic and Monetary Union and the increasing use of electronic payment instruments. The third chapter deals with the implications of developments in ICT on relationship banking. The financial intermediation literature explains relationship banking as a type of financial intermediation characterised by proprietary information and multiple interactions with customers. This form of banking is important for the financing of small and medium-sized enterprises. We discuss the effects of ICT on the banking sector as a whole and then apply these developments to the case of relationship banking. The fourth chapter is an empirical study of the effects of technology on the banking business, using a sample of data from the Spanish banking industry. The design of the study is based on some of the events described in the previous chapters, and also draws from the economic literature on banking. The study shows that developments in information management have differential effects on wholesale and retail banking activities. Finally, the last chapter is a technology assessment study on electronic payments systems in Spain and the European Union. It contains an analysis of existing payment systems and ongoing or planned initiatives in Spain. It forms part of a broader project comprising a series of country-specific analyses covering ten European countries. The main issues raised across the countries serve as the starting point to discuss implications of the development of electronic money for regulation and policies, and in particular, for monetary-policy making.

Eye tracking data representation and visualization : on information and communication studies at CETAC.MEDIA

Eye tracking has become a preponderant technique in the evaluation of user interaction and behaviour with study objects in defined contexts. Common eye tracking related data representation techniques offer valuable input regarding user interaction and eye gaze behaviour, namely through fixations and saccades measurement. However, these and other techniques may be insufficient for the representation of acquired data in specific studies, namely because of the complexity of the study object being analysed. This paper intends to contribute with a summary of data representation and information visualization techniques used in data analysis within different contexts (advertising, websites, television news and video games). Additionally, several methodological approaches are presented in this paper, which resulted from several studies developed and under development at CETAC.MEDIA - Communication Sciences and Technologies Research Centre. In the studies described, traditional data representation techniques were insufficient. As a result, new approaches were necessary and therefore, new forms of representing data, based on common techniques were developed with the objective of improving communication and information strategies. In each of these studies, a brief summary of the contribution to their respective area will be presented, as well as the data representation techniques used and some of the acquired results.

Drivers and barriers to digital television adoption in Portugal: the perspectives of the TV viewers and other main stakeholders

To understand what are the most significant factors for digital TV adoption by the Portuguese population in the switchover context is the main goal of the research project here presented. In April 26, 2012, the analogue terrestrial television switchoff is planned to occur in Portugal, according to the schedule published by the national telecommunication regulator Anacom. Digital terrestrial TV was launched in the country in April 2009, making Portugal one of the countries with a more ambitious schedule – or risky, depending on the perspective - for the full transition from analogue to digital terrestrial television. In this paper we will start by presenting the research project’s objectives, theoretical framework and research design. Next, we will present first results of the project focused on the barriers and drivers to digital TV adoption from two of the empirical studies which integrate it, namely, the quantitative inquiry administered to a representative sample of the Portuguese population and interviews with main stakeholders in the area of digital TV in Portugal. The perspectives of the television viewers are compared with other main stakeholders in this process. The paper will be concluded with a brief discussion of these results and a brief enumeration of next steps for the project.

Incentives and Barriers to the Adoption of Digital Terrestrial Television in Portugal: Perspectives of the stakeholders involved in the transition process

The success of the transition from analogical terrestrial television to digital terrestrial television – process also known as switch-over – requires the identification of barriers and drivers among the impacted population. Therefore, the study in which this article is based had as main purpose to understand exactly what are those barriers, in order to produce a valid contribution to the several decision makers, and to be able to contribute to a more inclusive television, accessible and transversal to the whole of the population. In that sense, one of the phases of the project consisted in several interviews to key stakeholders in the transition process, the results of which and subsequent recommendations are presented in this article.

Universal Museum - universal language? Art historian - curator

Marshal McLuhan’s prophetic vision of the global village is about to be realized. If we are aware of the fact that mass communication reduces the dimensions of our world and makes it more unified and universal, we should take this into consideration when planning the Universal Museum and the language that should be used in it. As curators, educators and museum staff we should not ignore the fact that the spectator/viewer is drawn to the exhibits not only by their own merit, but also guided and assisted by verbal messages, i. e. Labels, brochures. Catalogues etc. Hence, the crucial question is what we, the museologists, use as a means of communication when preparing for a Universal Museum. Should we use pictorial semiotics? This may be a partial solution, which is mainly restricted to objects that can be manipulated and moved by the visitor, as is the case in most of the technological museums. But since the range of objects on display at museums is vast and varied - fine art, archaeological finds, ethnographic objects etc., it may not be the answer to the whole spectrum of exhibits. Dr. Ludwig Lazarus Zamenhof, being an optimist, hoped that by introducing Esperanto to the multi-lingual world population, humanity would be able to bridge and diminish the gap of linguistic differences, thus creating a better understanding between the international communities. Unfortunately this vision was not realized. Esperanto was and still is an utopian and esoteric phenomenon. The barriers between nations still exist although, as mentioned earlier, mass media do help, in some ways, to reduce them.

A qualidade de vida de adolescentes com cegueira congénita ou precoce em Portugal : implicações na construção da personalidade e da vida adulta

Qualidade de Vida é um conceito muito complexo que, basicamente, define a percepção que um indivíduo tem acerca da sua situação na vida, de acordo com o contexto cultural e com os sistemas de valores nos quais vive, sendo essa percepção o resultado da interacção entre os objectivos e expectativas individuais e os indicadores objectivos disponíveis para o ambiente sócio-cultural em que o indivíduo está inserido. Sendo um período de crescimento, de desenvolvimento e de novas oportunidades, mas, simultaneamente, de desafios e incertezas, a adolescência traz consigo tensões e ansiedades que interferem, necessariamente, com o bem-estar dos jovens. Para além das tensões inerentes a este período de grandes transformações, os adolescentes portadores de cegueira congénita ou precoce têm ainda de gerir as tensões provocadas pelo confronto diário - necessariamente desgastante - com as barreiras de carácter académico, social e afectivo que, decorrentes das concepções altamente depreciativas da sociedade - nomeadamente da sociedade portuguesa - relativamente à cegueira, condicionam fortemente a inclusão social destes jovens. Foram entrevistados três adolescentes cegos: dois do sexo feminino - com 19 e 16 anos, respectivamente, e frequentando, à data da entrevista, uma o Ensino Superior, e a outra o Ensino Secundário - e um do sexo masculino, com 15 anos, que, quando foi entrevistado, frequentava o Ensino Básico. Foram colocadas aos participantes na pesquisa questões que visaram o conhecimento dos aspectos mais relevantes da vida de cada um deles ao nível das várias dimensões a considerar, de modo a podermos, em cada caso, realizar uma avaliação da qualidade de vida e do impacto nela provocado pelas circunstâncias directa e indirectamente associadas à cegueira. Embora constituam acima de tudo pistas para futuras investigações na medida em que são referentes ao estudo de alguns casos, os resultados obtidos indiciam muito claramente que, em Portugal, a qualidade de vida dos adolescentes portadores de cegueira congénita ou precoce é fortemente afectada, quer pelas concepções muito penalizantes detidas pela nossa sociedade relativamente à cegueira, quer pelas barreiras físicas, logísticas, académicas, sociais e afectivas delas decorrentes.
