    As a process inherent to the HCI area, UX Research can be seen as a strategy that supports the development of digital products, namely when usability and accessibility guidelines are used to drive the approach adopted. Practices and strategies based on user experience can facilitate understanding the generation of inputs to drive the digital products development as well as support requirements. In this context, this research is focused on the observation of the UX Research process in the development of the new web portal of the University of Aveiro aiming to investigate how UX Research practice can support the methodological approach used, regarding requirements support, identification of typology interface problems, and collection of information towards the continuous improvement of the development of the University of Aveiro (UA) New Portal. For this purpose, a Mixed Methodology was used based on the Grounded Theory framework, by the inductive process of data observation, delimited to the observation of the new News area of the web portal. Data saturation allowed us to know which UX Research sources had more capacity to raise data from the end-users, support requirements, identify types of interface problems, and supply the development of product solutions. As a consequence of the data processing, this research presents a UXR flow proposal to support data collection and engage stakeholders with the end-user needs and interests.Como um processo inerente à área de Interação Humano-Computador (HCI), a Investigação em Experiência do Utilizador (UX Research) pode ser vista como uma estratégia de apoio ao desenvolvimento de produtos digitais quando princípios de usabilidade e acessibilidade são utilizados para impulsionar a abordagem adoptada. Práticas e estratégias baseadas na coleta de dados relativos à experiência do utilizador podem facilitar a geração de inputs para impulsionar desenvolvimento de produtos digitais bem como suportar a defesa de requisitos. Neste contexto, esta investigação está centrada na observação do processo de UX Research no desenvolvimento do novo portal web da Universidade de Aveiro com o objetivo de compreender como a prática da Investigação em UX pode apoiar a abordagem metodológica utilizada, no que diz respeito ao suporte de requisitos, identificação de tipologias de problemas da interface, e recolha de informação para a melhoria contínua do desenvolvimento do Novo Portal da Universidade de Aveiro (UA). Para este fim, foi utilizada uma Metodologia Mista, Qualiquantitativa fundamentada na estrutura de Grounded Theory, em que parte-se do processo indutivo da observação dos dados, delimitado à observação da nova Área de Notícias do portal web. O tratamento estatístico permitiu saber quais as fontes da UX Research com maior capacidade para levantar dados dos utilizadores finais, qual delas mais dá suporte aos requisitos, ajuda na identificação de tipos de problemas da interface, e apoia o desenvolvimento de soluções de produto. Como consequência do processamento de dados, esta investigação apresenta uma proposta de fluxo de Investigação em UX para apoiar a recolha de dados e motivar os envolvidos no processo para atender as necessidades e interesses dos utilizadores finais.Mestrado em Comunicação Multimédi

    Towards the optimal Pixel size of dem for automatic mapping of landslide areas

    Determining appropriate spatial resolution of digital elevation model (DEM) is a key step for effective landslide analysis based on remote sensing data. Several studies demonstrated that choosing the finest DEM resolution is not always the best solution. Various DEM resolutions can be applicable for diverse landslide applications. Thus, this study aims to assess the influence of special resolution on automatic landslide mapping. Pixel-based approach using parametric and non-parametric classification methods, namely feed forward neural network (FFNN) and maximum likelihood classification (ML), were applied in this study. Additionally, this allowed to determine the impact of used classification method for selection of DEM resolution. Landslide affected areas were mapped based on four DEMs generated at 1m, 2m, 5m and 10m spatial resolution from airborne laser scanning (ALS) data. The performance of the landslide mapping was then evaluated by applying landslide inventory map and computation of confusion matrix. The results of this study suggests that the finest scale of DEM is not always the best fit, however working at 1m DEM resolution on micro-topography scale, can show different results. The best performance was found at 5m DEM-resolution for FFNN and 1m DEM resolution for results. The best performance was found to be using 5m DEM-resolution for FFNN and 1m DEM resolution for ML classification

    Why social scientists should engage with natural scientists

    Get PDF
    It has become part of the mantra of contemporary science policy that the resolution of besetting problems calls for the active engagement of a wide range of sciences. The paper reviews some of the key challenges for those striving for a more impactful social science by engaging strategically with natural scientists. It argues that effective engagement depends upon overcoming basic assumptions that have structured past interactions: particularly, the casting of social science in an end-of-pipe role in relation to scientific and technological developments. These structurings arise from epistemological assumptions about the underlying permanence of the natural world and the role of science in uncovering its fundamental order and properties. While the impermanence of the social world has always put the social sciences on shakier foundations, twenty-first century concerns about the instability of the natural world pose different epistemological assumptions that summon a more equal, immediate and intense interaction between field and intervention oriented social and natural scientists. The paper examines a major research programme that has exemplified these alternative epistemological assumptions. Drawing on a survey of researchers and other sources it seeks to draw out the lessons for social/natural science cross-disciplinary engagement

    Strategic environmental assessment implementation of transport and mobility plans. The case of italian regions and provinces

    Get PDF
    Transport and mobility plans imply strategies and actions that affect the environment. The European Union has introduced in 2001 the strategic environmental assessment (SEA) to take into account and mitigate adverse environmental effects in planning and decision-making. SEA limited implementation has attracted the interest of many scholars that have sought methods able to assess the quality of SEA processes by identifying vices and virtues in practice. In this paper, we measure the quality of eight SEAs for transport and mobility plans of regional and provincial administrations of Italy. Results show that the overall quality level of SEA reports is only barely sufficient, Abruzzo is among the virtuous and Piedmont among the critical administrations. We also stress that the determination of impact significance has received the worse quality score. We finally compare our results to other Italian and British homologous cases finding interesting and generally confirmative evidence

    What young people want from health-related online resources: a focus group study

    Get PDF
    The growth of the Internet as an information source about health, particularly amongst young people, is well established. The aim of this study was to explore young people's perceptions and experiences of engaging with health-related online content, particularly through social media websites. Between February and July 2011 nine focus groups were facilitated across Scotland with young people aged between 14 and 18 years. Health-related user-generated content seems to be appreciated by young people as a useful, if not always trustworthy, source of accounts of other people's experiences. The reliability and quality of both user-generated content and official factual content about health appear to be concerns for young people, and they employ specialised strategies for negotiating both areas of the online environment. Young people's engagement with health online is a dynamic area for research. Their perceptions and experiences of health-related content seem based on their wider familiarity with the online environment and, as the online environment develops, so too do young people's strategies and conventions for accessing it

    Responding to the vision of the information society: first steps towards a national virtual university.

    Executive Summary 1. There is confusion, both in academic circles and the public more generally, about the definition of a virtual university. Hence in considering such an option, it is worth looking more fundamentally at the contexts for higher education, and the functions of a National Virtual University equipped to meet the needs of the 21st Century. 2. The increase in the use of ICT has caused a radical increase in demand for higher education globally, and increased access to higher education via the use of ICT. New suppliers in the form of private and corporate universities, now compete with universities in their home countries, and increasingly, overseas. 3. Although demands for higher education are growing rapidly, analysis of the new and changing demands on universities at local, national and international levels, within an increasingly global knowledge market, indicates that the role of a National Virtual University will be much broader than that of an existing university. Moreover, a NVU will need to successfully compete in an environment which is growing in competitiveness and complexity as corporate universities start to operate, but will have to do so with greater efficiency and lower funding. 4. The socio-economic environment in Finland is characterised by an internationally high (and growing) involvement with information and communication technologies in all spheres of life. Within this fast developing Information Society, there is a high need for increasing skills levels and retraining, especially with respect to ICT. However, like elsewhere in Europe, the use of technology for collaborative teaching in Universities and for promoting joint research with industry, is comparatively underexploited, although the existing higher education platform, provides a useful structure which could adapt to, and benefit from, the establishment of a National Virtual University. 5. The rationale for incorporating the use of new technologies in higher education by building a National Virtual University is well-established. Such a development would require a quantum leap in the design and development of a new learning method. However, in addition to educational benefits, the NVU would aid the creation of a knowledge based economy, the promotion of social cohesion, the protection of the existing Finnish university system, and the preservation of national language and culture. 6. The experience of previous virtual university ventures in the USA demonstrates that collaborative ventures, based on existing providers and reliant on reengineering of existing teaching and learning practices, are unlikely to be successful, even where they are well financed. A National Virtual University can be constructed with varying degrees of functionality, but where it covers all ranges of university activities (teaching, research and technology transfer), and is well-linked to the local community, the cost of development will be high but the returns on expenditure will be greatest. 7. A project of this size, complexity, cost and importance will only succeed in maximising its potential as a collaborative venture, if it involves all stakeholder groups in discussing its form, as consensus on the form of the NVU will be critical in ensuring the success of its implementation
