    Contextual Social Networking

    Get PDF
    The thesis centers around the multi-faceted research question of how contexts may be detected and derived that can be used for new context aware Social Networking services and for improving the usefulness of existing Social Networking services, giving rise to the notion of Contextual Social Networking. In a first foundational part, we characterize the closely related fields of Contextual-, Mobile-, and Decentralized Social Networking using different methods and focusing on different detailed aspects. A second part focuses on the question of how short-term and long-term social contexts as especially interesting forms of context for Social Networking may be derived. We focus on NLP based methods for the characterization of social relations as a typical form of long-term social contexts and on Mobile Social Signal Processing methods for deriving short-term social contexts on the basis of geometry of interaction and audio. We furthermore investigate, how personal social agents may combine such social context elements on various levels of abstraction. The third part discusses new and improved context aware Social Networking service concepts. We investigate special forms of awareness services, new forms of social information retrieval, social recommender systems, context aware privacy concepts and services and platforms supporting Open Innovation and creative processes.

Die (noch nicht abgeschlossene) erfolgreiche Umsetzung dieses Programmes fĂĽhrt auf ein Konzept, das man als Contextual Social Networking bezeichnen kann. In einem grundlegenden ersten Teil werden die eng zusammenhängenden Gebiete Contextual Social Networking, Mobile Social Networking und Decentralized Social Networking mit verschiedenen Methoden und unter Fokussierung auf verschiedene Detail-Aspekte näher beleuchtet und in Zusammenhang gesetzt. Ein zweiter Teil behandelt die Frage, wie soziale Kurzzeit- und Langzeit-Kontexte als fĂĽr das Social Networking besonders interessante Formen von Kontext gemessen und abgeleitet werden können. Ein Fokus liegt hierbei auf NLP Methoden zur Charakterisierung sozialer Beziehungen als einer typischen Form von sozialem Langzeit-Kontext. Ein weiterer Schwerpunkt liegt auf Methoden aus dem Mobile Social Signal Processing zur Ableitung sinnvoller sozialer Kurzzeit-Kontexte auf der Basis von Interaktionsgeometrien und Audio-Daten. Es wird ferner untersucht, wie persönliche soziale Agenten Kontext-Elemente verschiedener Abstraktionsgrade miteinander kombinieren können. Der dritte Teil behandelt neuartige und verbesserte Konzepte fĂĽr kontextbewusste Social Networking Dienste. Es werden spezielle Formen von Awareness Diensten, neue Formen von sozialem Information Retrieval, Konzepte fĂĽr kontextbewusstes Privacy Management und Dienste und Plattformen zur UnterstĂĽtzung von Open Innovation und Kreativität untersucht und vorgestellt.

    Improving access to high-quality primary care for socioeconomically disadvantaged older people in rural areas: a mixed method study protocol

    Get PDF
    Introduction: The UK has an ageing population, especially in rural areas, where deprivation is high among older people. Previous research has identified this group as at high risk of poor access to healthcare. The aim of this study is to generate a theory of how socioeconomically disadvantaged older people from rural areas access primary care, to develop an intervention based on this theory and test it in a feasibility trial. Methods and analysis: On the basis of the MRC Framework for Developing and Evaluating Complex Interventions, three methods will be used to generate the theory. First, a realist review will elucidate the patient pathway based on existing literature. Second, an analysis of the English Longitudinal Study of Ageing will be completed using structural equation modelling. Third, 15 semistructured interviews will be undertaken with patients and four focus groups with health professionals. A triangulation protocol will be used to allow each of these methods to inform and be informed by each other, and to integrate data into one overall realist theory. Based on this theory, an intervention will be developed in discussion with stakeholders to ensure that the intervention is feasible and practical. The intervention will be tested within a feasibility trial, the design of which will depend on the intervention. Lessons from the feasibility trial will be used to refine the intervention and gather the information needed for a definitive trial. Ethics and dissemination: Ethics approval from the regional ethics committee has been granted for the focus groups with health professionals and interviews with patients. Ethics approval will be sought for the feasibility trial after the intervention has been designed. Findings will be disseminated to the key stakeholders involved in intervention development, to researchers, clinicians and health planners through peer-reviewed journal articles and conference publications, and locally through a dissemination event

    Children and young people’s experiences of completing mental health and wellbeing measures for research: learning from two school-based pilot projects

    Get PDF
    BACKGROUND: In recent years there has been growing interest in child and adolescent mental health and wellbeing, alongside increasing emphasis on schools as a crucial site for research and intervention. This has coincided with an increased use of self-report mental health and wellbeing measures in research with this population, including in school-based research projects. We set out to explore the way that children and young people perceive and experience completing mental health and wellbeing measures, with a specific focus on completion in a school context, in order to inform future measure and research design. METHODS: We conducted semi-structured interviews and focus groups with 133 participants aged 8–16 years following their completion of mental health and wellbeing measures as part of school-based research programmes, using thematic analysis to identify patterns of experience. FINDINGS: We identified six themes: Reflecting on emotions during completion; the importance of anonymity; understanding what is going to happen; ease of responding to items; level of demand; and interacting with the measure format. CONCLUSIONS: Our findings offer greater insight into children and young people’s perceptions and experiences in reporting on their mental health and wellbeing. Such understanding can be used to support more ethical and robust data collection procedures in child and adolescent mental health research, both for data quality and ethical purposes. We offer several practical recommendations for researchers, including facilitating this in a school context

    Podcast production and marketing strategies on the main platforms in Europe, North America, and Latin America. Situation and perspectives

    Get PDF
    Fifteen years after the term was coined, the podcast is now consolidated as a sound format with a specific identity within the digital media ecosystem. The practice of podcasting is none other than radio, but one encompassing diverse production on both expressive and thematic levels whose properties (mobility, narrative fragmentation, and the integration of multiple devices) and personalized consumption generate a very different listener attitude compared with traditional radio. After an initial period of independent amateurism strongly conditioned by the technologies available, the podcast has achieved significant global popular recognition, as well as an increasingly important professional dimension thanks to the emergence and spread of new distribution platforms (podcast networks) designed to serve as alternatives to the dominant feeds (such as Apple Podcasts, Google Podcasts, iVoox, and Spotify) that rely on different catalogs and business models. This investigation identifies, describes, and systematically orders the main management and marketing models for podcasts on these platforms on the basis of a comparative analysis of fourteen of them, two in each of the eight countries in Europe, North America, and Latin America where this format is most widespread: Acast (Sweden); Podimo (Denmark); Binge Audio and Majelan (France); Podimo Spain and Podium Podcast (Spain); PodcastOne and Luminary (USA); Convoy Network and Puentes (Mexico); Posta and Parque Podcast (Argentina); and Pia Podcast and Podway (Colombia). The study measures and compares the offerings of each of the studied platforms using different quantitative and qualitative variables (age, territorial reach, content categories, dominant genres, funding, and consumption). The objective is to start to draw up a global map of the main operators in the podcasting industry, and to identify the production trends and marketing strategies of a format with increasing impact and demand, destined to become the future heir of broadcast radio
