    Diverse perceptions of smart spaces

    No full text
    This is the era of smart technology and of ‘smart’ as a meme, so we have run three workshops to examine the ‘smart’ meme and the exploitation of smart environments. The literature relating to smart spaces focuses primarily on technologies and their capabilities. Our three workshops demonstrated that we require a stronger user focus if we are advantageously to exploit spaces ascribed as smart: we examined the concept of smartness from a variety of perspectives, in collaboration with a broad range of contributors. We have prepared this monograph mainly to report on the third workshop, held at Bournemouth University in April 2012, but do also consider the lessons learned from all three. We conclude with a roadmap for a fourth (and final) workshop, which is intended to emphasise the overarching importance of the humans using the spac

    Developing the scales on evaluation beliefs of student teachers

    The purpose of the study reported in this paper was to investigate the validity and the reliability of a newly developed questionnaire named ‘Teacher Evaluation Beliefs’ (TEB). The framework for developing items was provided by the two models. The first model focuses on Student-Centered and Teacher-Centered beliefs about evaluation while the other centers on five dimensions (what/ who/ when/ why/ how). The validity and reliability of the new instrument was investigated using both exploratory and confirmatory factor analysis study (n=446). Overall results indicate that the two-factor structure is more reasonable than the five-factor one. Further research needs additional items about the latent dimensions “what” ”who” ”when” ”why” “how” for each existing factor based on Student-centered and Teacher-centered approaches

    This report explored teaching practices, beliefs and teaching styles and their influences on ICT use and implementation by pupils. Additional factors explored included the value of school and LEA policies and teacher competence in the use of ICT in classroom settings. ImpaCT2 was a major longitudinal study (1999-2002) involving 60 schools in England, its aims were to: identify the impact of networked technologies on the school and out-of-school environment; determine whether or not this impact affected the educational attainment of pupils aged 816 years (at Key Stages 2, 3, and 4); and provide information that would assist in the formation of national, local and school policies on the deployment of IC

    Designing instruments towards networked music practices

    It is commonly noted in New Interfaces for Musical Expression (NIME) research that few of these make it to the mainstream and are adopted by the general public. Some research in Sound and Music Computing (SMC) suggests that the lack of humanistic research guiding technological development may be one of the causes. Many new technologies are invented, however without real aim else than for technical innovation, great products however emphasize the user-friendliness, user involvement in the design process or User-Centred Design (UCD), that seek to guarantee that innovation address real, existing needs among users. Such an approach includes not only traditionally quantifiable usability goals, but also qualitative, psychological, philosophical and musical such. The latter approach has come to be called experience design, while the former is referred to as interaction design. Although the Human Computer Interaction (HCI) community in general has recognized the significance of qualitative needs and experience design, NIME has been slower to adopt this new paradigm. This thesis therefore attempts to investigate its relevance in NIME, and specifically Computer Supported Cooperative Work (CSCW) for music applications by devising a prototype for group music action based on needs defined from pianists engaging in piano duets, one of the more common forms of group creation seen in the western musical tradition. These needs, some which are socio-emotional in nature, are addressed through our prototype although in the context of computers and global networks by allowing for composers from all over the world to submit music to a group concert on a Yamaha Disklavier in location in Porto, Portugal. Although this prototype is not a new gestural controller per se, and therefore not a traditional NIME, but rather a platform that interfaces groups of composers with a remote audience, the aim of this research is on investigating how contextual parameters like venue, audience, joint concert and technologies impact the overall user experience of such a system. The results of this research has been important not only in understanding the processes, services, events or environments in which NIME’s operate, but also understanding reciprocity, creativity, experience design in Networked Music practices.É de conhecimento generalizado que na área de investigação em novos interfaces para expressão musical (NIME - New Interfaces for Musical Expression), poucos dos resultantes dispositivos acabam por ser popularizados e adoptados pelo grande público. Algum do trabalho em computação sonora e musical (SMC- Sound and Music Computing) sugere que uma das causas para esta dificuldade, reside numalacuna ao nível da investigação dos comportamentos humanos como linha orientadora para os desenvolvimentos tecnológicos. Muitos dos desenvolvimentos tecnológicos são conduzidos sem um real objectivo, para além da inovação tecnológica, resultando em excelentes produtos, mas sem qualquer enfâse na usabilidade humana ou envolvimento do utilizador no processo de Design (UCDUser Centered Design), no sentido de garantir que a inovação atende a necessidades reais dos utilizadores finais. Esta estratégia implica, não só objectivos quantitativos tradicionais de usabilidade, mas também princípios qualitativos, fisiológicos, psicológicos e musicológicos. Esta ultima abordagem é atualmente reconhecida como Design de Experiência (Experience Design) enquanto a abordagem tradicional é vulgarmente reconhecida apenas como Design de Interação (Interaction Design). Apesar de na área Interação Homem-Computador (HCI – Human Computer Interaction) as necessidades qualitativas no design de experiência ser amplamente reconhecido em termos do seu significado e aplicabilidade, a comunidade NIME tem sido mais lenta em adoptar este novo paradigma. Neste sentido, esta Tese procura investigar a relevância em NIME, especificamente nu subtópico do trabalho cooperativo suportado por Computadores (CSCW – Computer Supported Cooperative Work), para aplicações musicais, através do desenvolvimento de um protótipo de um sistema que suporta ações musicais coletivas, baseado nas necessidades especificas de Pianistas em duetos de Piano, uma das formas mais comuns de criação musical em grupo popularizada na tradição musical ocidental. Estes requisitos, alguns sócioemocionais na sua natureza, são atendidos através do protótipo, neste caso aplicado ao contexto informático e da rede de comunicações global, permitindo a compositores de todo o mundo submeterem a sua música para um concerto de piano em grupo num piano acústico Yamaha Disklavier, localizado fisicamente na cidade do Porto, Portugal. Este protótipo não introduz um novo controlador em si mesmo, e consequentemente não está alinhado com as típicas propostas de NIME. Trata-se sim, de uma nova plataforma de interface em grupo para compositores com uma audiência remota, enquadrado com objectivos de experimentação e investigação sobre o impacto de diversos parâmetros, tais como o espaço performativo, as audiências, concertos colaborativos e tecnologias em termos do sistema global. O resultado deste processo de investigação foi relevante, não só para compreender os processos, serviços, eventos ou ambiente em que os NIME podem operar, mas também para melhor perceber a reciprocidade, criatividade e design de experiencia nas práticas musicais em rede

    Designing Scalable Business Models

    Digital business models are often designed for rapid growth, and some relatively young companies have indeed achieved global scale. However despite the visibility and importance of this phenomenon, analysis of scale and scalability remains underdeveloped in management literature. When it is addressed, analysis of this phenomenon is often over-influenced by arguments about economies of scale in production and distribution. To redress this omission, this paper draws on economic, organization and technology management literature to provide a detailed examination of the sources of scaling in digital businesses. We propose three mechanisms by which digital business models attempt to gain scale: engaging both non- paying users and paying customers; organizing customer engagement to allow self- customization; and orchestrating networked value chains, such as platforms or multi-sided business models. Scaling conditions are discussed, and propositions developed and illustrated with examples of big data entrepreneurial firms
