Las personas con discapacidad a menudo se encuentran con problemas de acceso a las Tecnologías de la Información y la Comunicación (TIC), debido a diseños y desarrollos que no tienen en cuenta sus diferencias funcionales, y en consecuencia se encuentran en riesgo de exclusión social. Cada vez es más común encontrar productos de apoyo que permitan utilizar diferentes tecnologías (ordenadores, Internet, dispositivos móviles), pero muchos de ellos no se encuentran integrados debido a que funcionan esencialmente modificando la plataforma donde están instalados, siendo soluciones de acceso de segunda generación. Más allá del desarrollo de los productos de apoyo, que sin duda ha evolucionado positivamente en los últimos años, cabe resaltar que existe una falta de herramientas y de aproximación holística que ayuden a los desarrolladores y diseñadores hacer las TIC accesibles. Esta tesis doctoral pretende validar la hipótesis de que una metodología holística de desarrollo de aplicaciones y productos de apoyo TIC, llamada Marco Abierto Accesible, facilita el desarrollo y la integración de modo nativo de la accesibilidad en las aplicaciones y productos apoyo, independientemente de la tecnología utilizada, dando lugar a soluciones de acceso de tercera generación que permitan mejorar la utilización de dichas aplicaciones por parte de personas con discapacidad. Este trabajo se ha desarrollado en el marco del proyecto AEGIS (del inglés, open Accessibility Everywhere: Groundwork, Infrastructure, Standards), que fue parcialmente financiado por la Comisión Europea (CE) bajo el VII Programa Marco y tuvo una duración de cuatro años. La metodología para el diseño, desarrollo y validación seguida en esta tesis es una adaptación de dos metodologías de diseño existentes (el Diseño Centrado en el Usuario y el Diseño Orientado a Metas), la implementación del Marco Abierto Accesible y el uso de diferentes técnicas de validación. Además se ha desarrollado un marco metodológico de entrenamiento para minimizar el efecto que tiene la curva de aprendizaje cuando los usuarios prueban por primera vez las soluciones desarrolladas. En esta tesis se presenta el Marco Abierto Accesible aplicado a las TIC en las tres áreas en las que se desarrolla este trabajo: ordenadores, Internet y dispositivos móviles, partiendo de las necesidades y problemas que tienen los usuarios con discapacidad en el uso de las TIC. Diferentes instanciaciones del Marco Abierto Accesible se definen en las tres áreas TIC mencionadas anteriormente y se describen varios ejemplos de sus implementaciones particulares. Los resultados de las evaluaciones de las implementaciones particulares con usuarios finales y expertos, una vez discutidos y contrastados con las hipótesis, sirven para probar la validez del Marco Abierto Accesible para la integración nativa de productos de apoyo en Tecnologías de la Información y la Comunicación. Finalmente, se presentan las líneas de investigación y trabajo futuro en el área de la accesibilidad en las TIC. ABSTRACT People with disabilities often encounter problems of access to Information and Communications Technology (ICT), due to design and developments that do not take into account their functional differences and therefore put them at risk of social exclusion. It is increasingly common to find assistive products that allow to use different technologies (computers, Internet, mobile devices), but many of them are not well integrated because they work essentially modifying the platform where they are installed, beeing the second-generation access solutions. Beyond the assistive product development, which has certainly evolved positively in recent years, it is notable that there is a lack of tools and holistic approach to help developers and designers make accessible ICT. This doctoral thesis aims to validate the hypothesis that a holistic approach to application development and assistive ICT products, called Open Accessibility Framework, facilitates the development and integration of native accessible applications and assistive products, regardless of the technology used, resulting in third-generation access solutions that improve the use of such applications by people with disabilities. This work was developed under the AEGIS project (open Accessibility Everywhere: Groundwork, Infrastructure, Standards), which was partially funded by the European Commission (EC) under the Seventh Framework Programme and lasted four years. The methodology for the design, development and validation followed in this thesis is an adaptation of two existing design methodologies (User Centered Design and Goal Oriented Design), the implementation of the Open Accessibility Framework and the usage of different validation techniques. A training methodological framework ha also been developed to minimize the effect of the learning curve when users first try the solutions developed. This thesis presents the Open Accessibility Framework applied to ICT in three areas in which this work is developed: computers, Internet and mobile devices, based on the needs and problems of the disabled users in the use of ICT. Different instantiations of the Open Accessibility Framework are defined in the three aforementioned ICT areas and various examples of its particular implementations are described. The results of the evaluations of the particular implementations which have been carried with end users and experts, once discussed and contrasted with the hypotheses, have been used to test the validity of the Open Accessibility Framework for the native integration of assistive products in Information and Communications Technology. Finally, the future research lines and future work in the area of ICT accessibility are presented.

This article describes the adaptation and validation of the Distance Education Learning Environments Survey (DELES) for use in investigating the qualities found in distance and hybrid education psycho-social learning environments in Spain. As Europe moves toward post-secondary student mobility, equanimity in access to higher education, and more standardised degree programs across the European Higher Education Area (EHEA) the need for a high quality method for continually assessing the excellence of distance and hybrid learning environments has arisen. This study outlines how the English language DELES was adapted into the new Spanish-Distance Education Learning Environments Survey (S-DELES) for use with a Bachelor of Psychology and Criminology degree program offering both distance and hybrid education classes. We present the relationships between psycho-social learning environment perceptions and those of student affect. We also present the asynchronous aspects of the environment, scale means, and a comparison between the perceptions of distance education students and their hybrid education counterparts that inform the university about the baseline health of the information and communication technologies (ICT) environment within which the study was conducted.

In order to increase the use of information and communication technologies (ICT) in the European Union Member States, the European Commission, on the initiative of Commissioner E. Liikannen, launched in December 1999 a bold programme called “eEurope”. Soon after its creation, the eEurope programme was integrated into the so- called Lisbon agenda for Europe to become the “most advanced knowledge based economy” in the world. We try to assess if the programme is successful in achieving its stated objective of promoting a knowledge based economy through the development of an “information society for all”. First, we conclude that eEurope, due to its origins and its procedures, has intrinsic limits both as regards its scope and effectiveness. Second, we show how Member States have adopted different trajectories towards the “knowledge based society”. To identify these heterogeneous paths of growth, we have selected a set of variables that, combined together, represent the institutional arrangements specific to a country or a group of countries. We found sharp differences between two advanced models that we label, respectively, as Scandinavian and Anglo-Saxon. Without asserting the superiority of a model, we propose policy orientations to help Europe overcome those gaps hindering the move towards knowledge economies where information society technologies are widely diffused.

An on-line survey of experts was conducted to solicit their views on policy priorities in the area of information and communication technologies (ICT) in the Caribbean. The experts considered the goal to “promote teacher training in the use of ICTs in the classroom” to be the highest priority, followed by goals to “reduce the cost of broadband services” and “promote the use of ICT in emergency and disaster prevention, preparedness and response.” Goals in the areas of cybercrime, e-commerce, egovernment, universal service funds, consumer protection, and on-line privacy rounded out the top 10. Some of the lowest ranked goals were those related to coordinating the management of infrastructure changes. These included the switchover for digital terrestrial television (DTT) and digital FM radio, cloud computing for government ICT, the introduction of satellite-based internet services, and the installation of content distribution networks (CDNs). Initiatives aimed at using ICT to promote specific industries, or specific means of promoting the digital economy, tended toward the centre of the rankings. Thus, a general pattern emerged which elevated the importance of focusing on how ICT is integrated into the broader society, with economic issues a lower priority, and concerns about coordination on infrastructure issues lower still.

This paper investigates the simultaneous causal relationship between investments in information and communication technology (ICT) and flows of foreign direct investment (FDI), with reference to its implications on economic growth. For the empirical analysis we use data from 23 major countries with heterogeneous economic development for the period 1976-99. Our causality test results suggest that there is a causal relationship from ICT to FDI in developed countries, which means that a higher level of ICT investment leads to an increase inflow of FDI. ICT may contribute to economic growth indirectly by attracting more FDI. Contrarily, we could not find significant causality from ICT to FDI in developing countries. Instead, we have partial evidence of opposite causality relationship: the inflow of FDI causes further increases in ICT investment and production capacity. © United Nations University 2006.

Ensuring the security of corporate information, that is increasingly stored, processed and disseminated using information and communications technologies [ICTs], has become an extremely complex and challenging activity. This is a particularly important concern for knowledge-intensive organisations, such as universities, as the effective conduct of their core teaching and research activities is becoming ever more reliant on the availability, integrity and accuracy of computer-based information resources. One increasingly important mechanism for reducing the occurrence of security breaches, and in so doing, protecting corporate information, is through the formulation and application of a formal information security policy (InSPy). Whilst a great deal has now been written about the importance and role of the information security policy, and approaches to its formulation and dissemination, there is relatively little empirical material that explicitly addresses the structure or content of security policies. The broad aim of the study, reported in this paper, is to fill this gap in the literature by critically examining the structure and content of authentic information security policies, rather than simply making general prescriptions about what they ought to contain. Having established the structure and key features of the reviewed policies, the paper critically explores the underlying conceptualisation of information security embedded in the policies. There are two important conclusions to be drawn from this study: (1) the wide diversity of disparate policies and standards in use is unlikely to foster a coherent approach to security management; and (2) the range of specific issues explicitly covered in university policies is surprisingly low, and reflects a highly techno-centric view of information security management.

Despite the importance of information and communication technology (ICT) in the management of transport and logistics systems, there is a shortage of studies in the road freight haulage sector. This paper is aimed at filling this void through an exploratory survey on ICT adoption and the influencing factors carried out in the Italian road transport market. The paper provides a review of the previous research on this topic that allows the identification of research gaps that have been addressed through a questionnaire survey. The findings provide evidence of a passive stance on ICT usage characterised by the adoption of isolated applications. The financial risk associated with technology investment and human resources are the main barriers to ICT adoption, while the improvement of service level and the reliability of transport operations emerge as stimulating factors. The results suggest that the potential benefits of technology have not been fully exploited and a risk-sensitive stance on ICT is evident preventing the full incorporation of ICT into business processes.

Recent years have seen innovations in the logistics and freight transport industry in relation to Information and communication technologies (ICT) diffusion. The implementation of such technologies by third party logistics providers (3PLs) allows the real-time exchange of information between supply chain partners, thereby improving planning capability and customer service. However, the logistics and freight transport industry is lagging somewhat behind other sectors in ICT diffusion. In relation to the latter point, it is important to note that the dissemination of ICT in logistics and supply chain management (SCM) is shifting the 3PL industry to an increasingly knowledge-intensive approach. In this process, the role of learning becomes more central and an assessment of the impact of future ICT learning needs for the logistics providers is a strategic imperative. The aim of this paper is to assess the impact of ICT on logistics and freight transport industry in Italy and Ireland, and to identify learning needs for more effective ICT adoption in 3PLs.

This paper explores household pre-purchase practices and their mediation by information and communications technologies (ICTs), specifically online grocery shopping. Drawing on practice theory, the impacts of ICTs on household grocery shopping behavior are conceptualized, and the concept of "front-loading" is introduced. Emerging themes generated from 31 semi-structured interviews conducted via Skype with Turkish consumers focusing on their experiences of online grocery practices are presented. To this end, the contribution of this paper is twofold. First, an understanding of the domestication of online grocery shopping and its affect on the dynamics of household decision making, information sharing, and responsibilities of tasks before the actual act of online shopping is developed. Second, how such pre-purchase practices undertaken by consumers act as a catalyst of change at the industry level is appraised.

The integration of automation (specifically Global Positioning Systems (GPS)) and Information and Communications Technology (ICT) through the creation of a Total Jobsite Management Tool (TJMT) in construction contractor companies can revolutionize the way contractors do business. The key to this integration is the collection and processing of real-time GPS data that is produced on the jobsite for use in project management applications. This research study established the need for an effective planning and implementation framework to assist construction contractor companies in navigating the terrain of GPS and ICT use. An Implementation Framework was developed using the Action Research approach. The framework consists of three components, as follows: (i) ICT Infrastructure Model, (ii) Organizational Restructuring Model, and (iii) Cost/Benefit Analysis. The conceptual ICT infrastructure model was developed for the purpose of showing decision makers within highway construction companies how to collect, process, and use GPS data for project management applications. The organizational restructuring model was developed to assist companies in the analysis and redesign of business processes, data flows, core job responsibilities, and their organizational structure in order to obtain the maximum benefit at the least cost in implementing GPS as a TJMT. A cost-benefit analysis which identifies and quantifies the cost and benefits (both direct and indirect) was performed in the study to clearly demonstrate the advantages of using GPS as a TJMT. Finally, the study revealed that in order to successfully implement a program to utilize GPS data as a TJMT, it is important for construction companies to understand the various implementation and transitioning issues that arise when implementing this new technology and business strategy. In the study, Factors for Success were identified and ranked to allow a construction company to understand the factors that may contribute to or detract from the prospect for success during implementation. The Implementation Framework developed as a result of this study will serve to guide highway construction companies in the successful integration of GPS and ICT technologies for use as a TJMT.

Two concepts in rural economic development policy have been the focus of much research and policy action: the identification and support of clusters or networks of firms and the availability and adoption by rural businesses of Information and Communication Technologies (ICT). From a theoretical viewpoint these policies are based on two contrasting models, with clustering seen as a process of economic agglomeration, and ICT-mediated communication as a means of facilitating economic dispersion. The study’s conceptual framework is based on four interrelated elements: location, interaction, knowledge, and advantage, together with the concept of networks which is employed as an operationally and theoretically unifying concept. The research questions are developed in four successive categories: Policy, Theory, Networks, and Method. The questions are approached using a study of two contrasting groups of rural small businesses in West Cork, Ireland: (a) Speciality Foods, and (b) firms in Digital Products and Services. The study combines Social Network Analysis (SNA) with Qualitative Thematic Analysis, using data collected from semi-structured interviews with 58 owners or managers of these businesses. Data comprise relational network data on the firms’ connections to suppliers, customers, allies and competitors, together with linked qualitative data on how the firms established connections, and how tacit and codified knowledge was sourced and utilised. The research finds that the key characteristics identified in the cluster literature are evident in the sample of Speciality Food businesses, in relation to flows of tacit knowledge, social embedding, and the development of forms of social capital. In particular the research identified the presence of two distinct forms of collective social capital in this network, termed “community” and “reputation”. By contrast the sample of Digital Products and Services businesses does not have the form of a cluster, but matches more closely to dispersive models, or “chain” structures. Much of the economic and social structure of this set of firms is best explained in terms of “project organisation”, and by the operation of an individual rather than collective form of “reputation”. The rural setting in which these firms are located has resulted in their being service-centric, and consequently they rely on ICT-mediated communication in order to exchange tacit knowledge “at a distance”. It is this factor, rather than inputs of codified knowledge, that most strongly influences their operation and their need for availability and adoption of high quality communication technologies. Thus the findings have applicability in relation to theory in Economic Geography and to policy and practice in Rural Development. In addition the research contributes to methodological questions in SNA, and to methodological questions about the combination or mixing of quantitative and qualitative methods.

Esta investigación se propone identificar las actitudes y competencias de los estudiantes adultos en relación con el uso de las TIC, con especial atención al uso de plataformas digitales de aprendizaje y redes sociales (Web 2.0). Asimismo, evalúa la incidencia de algunas variables sociodemográficas (género y edad) en el uso estas herramientas y en la autopercepción de los estudiantes sobre sus competencias digitales. Se ha realizado un estudio tipo encuesta con una muestra de 382 estudiantes que acceden a la Universidad de Sevilla a través de las vías establecidas para mayores de 25, de 40 y 45 años. Los resultados ponen de manifiesto una actitud generalmente positiva ante las TIC que puede calificarse como de pragmática, ya que estas herramientas se valoran positivamente en función de sus potenciales beneficios en los procesos de aprendizaje. Se constata a la vez que no han recibido formación específica en el uso de las TIC. El nivel de competencia que este alumnado percibe tener en el uso de estos recursos es medio-bajo. Además, el grupo de estudiantes mayores de 45 años se considera menos competente que los mayores de 25 y de 40 años. En consecuencia, se realizan algunas propuestas para mejorar la participación de los estudiantes maduros en la enseñanza universitaria.

College radio is subject to constant transformation. The rise of information and communications technologies has allowed its development and modernization as well as the proliferation of new professional profiles. This research aims to analyze the connection of the Spanish university stations with the relevant qualifications. To do this, we use a comparative methodology based on examination of descriptors and specific principal subjects of degrees such as Audiovisual Communication and Journalism, although we will be using other degrees that are acquiring more responsibilities in a radio station, such as the degree in Information and Documentation. In conclusion, structural weaknesses in the university environment are observed, but future possibilities are detected as well: A college radio station is a place of convergence between the training of students from different degrees and reality itself, a versatile medium that provides the relevance of being the first professional contact of college students with the labor market.
