    Preserving Social Media: the Problem of Access

    Get PDF
    As the applications and services made possible through Web 2.0 continue to proliferate and influence the way individuals exchange information, the landscape of social science research, as well as research in the humanities and the arts, has the potential to change dramatically and to be enriched by a wealth of new, user-generated data. In response to this phenomenon, the UK Data Service have commissioned the Digital Preservation Coalition to undertake a 12-month study into the preservation of social media as part of the ‘Big Data Network’ programme funded by the Economic and Social Research Council (ESRC). The larger study focuses on the potential uses and accompanying challenges of data generated by social networking applications. This paper, ‘Preserving Social Media: the Problem of Access’, comprises an excerpt of that longer study, allowing the authors a space to explore in closer detail the issue of making social media archives accessible to researchers and students now and in the future. To do this, the paper addresses use cases that demonstrate the potential value of social media to academic social science. Furthermore, it examines how researchers and collecting institutions acquire and preserve social media data within a context of curatorial and legislative restrictions that may prove an even greater obstacle to access than any technical restrictions. Based on analysis of these obstacles, it will examine existing methods of curating and preserving social media archives, and second, make some recommendations for how collecting institutions might approach the long-term preservation of social media in a way that protects the individuals represented in the data and complies with the conditions of third party platforms. With the understanding that web-based communication technologies will continue to evolve, this paper will focus on the overarching properties of social media, analysing and comparing current methods of curation and preservation that provide sustainable solutions

    Hematodinium infection seasonality in the Firth of Clyde (Scotland) nephrops norvegicus population: a re-evaluation

    Hematodinium infections in Norway lobster Nephrops norvegicus from the Clyde Sea area (CSA) population, Scotland, UK, have previously been undetected in summer. This study aimed to establish if the CSA is actually devoid of infected N. norvegicus in this season. Two PCR assays, an ELISA and 2 tests that detect only patent infection (pleopod and body colour methods) were applied in a 21 mo study. Patent infection was seasonal, appearing predominantly in spring, while subpatent infection diagnosed by ELISA and PCR was highly prevalent in all seasons. Generalised linear modelling supported this assertion, as sampling in September and February significantly increased the probability of finding infected N. norvegicus (p < 0.01); infections were predominantly subpatent and patent respectively, at these times. Therefore, Hematodinium seasonality in N. norvegicus populations is likely to have been an artefact of insensitive diagnostic tests. Light Hematodinium infections were found using PCR assays when patent infections were at their most prevalent and intense, suggesting that infection develops at different rates in different N. norvegicus individuals and that only a portion of the total number of infected N. norvegicus die within a single year. These new data were added to a long-term data series for the CSA (1990 to 2008), which showed that after an initial 5 yr epidemic period, prevalence stabilised at 20 to 25%. Comparisons with ‘susceptible-infected-recovered/removed’ (SIR) models suggest that this high prevalence is maintained through high birth rates of susceptible host N. norvegicus

Isometric strength of the knee musculature, Centre-Of-Pressure (COP) based measures of balance, Berg Balance Scale (BBS), 10 m walk test, and the Subjective Index of Physical and Social Out come (SIPSO), were recorded at baseline, post-intervention, and after twelve weeks (follow-up). Exercise instructors delivered training once a week in a group format at a community centre. Significant improvement was noted in the BBS (p < 0.002), and 10 m walk speed (p = 0.03) post intervention which remained unchanged at follow-up. Total SIPSO score improved significantly post-intervention (p = 0.044). No other significant differences and no adverse effects were observed. It is possible that functional training provided more opportunity for the improvement of dynamic aspects of balance control that could be captured by the BBS but not with the traditional measures of balance using COP data. Results also suggest positive effects on the level of participation, and lack of association between measures of impairment and activity. Community based functional training could be effective and used to extend access to rehabilitation services beyond the acute and sub-acute stages after stroke.London Borough of Hillingdo

    Stroke units: The implementation of a complex intervention

    Get PDF
    This article reports on selected findings from an action research study that looked at the lessons learnt from setting up a new in-patient stroke service in a London teaching hospital. Key participants in the design and evaluation of this 2-year study included members of the multi-professional stroke team and support staff within the unit, the hospital management team and representatives of patients and carers. Mixed methods (focus groups, indepth interviews, audits, documentary analysis, participant observation field notes) were used to generate data. Findings demonstrated positive change overtime with four main themes emerging from the process: building a team; developing practice-based knowledge and skills in stroke; valuing the central role of the nurse in stroke care; and creating an organisational climate for supporting change. The interplay of these non-linear, but interrelated factors is supported by complexity theory, which includes exploration of how the sum of a whole can be more than its constituent parts. Findings are likely to be of interest to practitioners, managers and policy makers interested in supporting change in a learning organisation

    He Knows Who He\u27s Messing With : Hostile/Helpless Representations on the Parent Development Interview

    Get PDF
    Current systems for assessing parenting narratives lack the capacity to capture representational phenomena associated with significantly disrupted attachment relationships. This thesis will describe the adaptation of the valid and reliable Hostile/Helpless (HH) coding system for use with the Parent Development Interview (PDI). The hostile–helpless dyadic model posits that these two relational stances derive from an unbalanced internal working model of attachment that is shaped over the course of a caregiver’s own attachment history. Entering parenthood with hostile–helpless representation of caregiving puts a parent at risk of relating to their child from the extreme stance of either unbalanced behavioral position or of vacillating between their poles. Designed to aid in the identification of the most vulnerable parent–child relationships, the HH system for the PDI may have clinical and research value in the detection of disrupted caregiving and risk for maltreatment or disorganized attachment. This thesis will review the theoretical premise and empirical basis for this system, describe the preliminary adaptation process, and explore the HH caregiving narratives of three interviews in depth
