    Using Learning Analytics to Devise Interactive Personalised Nudges for Active Video Watching

    Videos can be a powerful medium for acquiring soft skills, where learning requires contextualisation in personal experience and ability to see different perspectives. However, to learn effectively while watching videos, students need to actively engage with video content. We implemented interactive notetaking during video watching in an active video watching system (AVW) as a means to encourage engagement. This paper proposes a systematic approach to utilise learning analytics for the introduction of adaptive intervention - a choice architecture for personalised nudges in the AVW to extend learning. A user study was conducted and used as an illustration. By characterising clusters derived from user profiles, we identify different styles of engagement, such as parochial learning, habitual video watching, and self-regulated learning (which is the target ideal behaviour). To find opportunities for interventions, interaction traces in the AVW were used to identify video intervals with high user interest and relevant behaviour patterns that indicate when nudges may be triggered. A prediction model was developed to identify comments that are likely to have high social value, and can be used as examples in nudges. A framework for interactive personalised nudges was then conceptualised for the case study

    Background New evidence with regard to a previously undocumented practice – self phlebotomy, known as ‘bloodletting’ – incontemporary injecting performance and image enhancing drug (PIED) culture is the subject of this paper. While self phlebotomy has been evidenced in psychiatric patients previously, it was performed here in people who inject AAS as a self directed health care procedure. Methods Data was collected from five publicly accessible internet discussion forums and coded using NVivo software. For the purposes of this study, posts in relation to bloodletting were extracted from the final set of records for analysis Results Motivation to perform bloodletting or to ‘self – bleed’ was largely grounded in experiencing symptoms of high blood pressure or a high red blood cell count (RBC).Instructions on how to perform bloodletting were found within discussion threads. Conclusion This study is intended to provide the first snapshot of online communal activity around practice of self-phlebotomy or bloodletting amongst people who inject AAS. Further research in this area is warranted, and will be of benefit to healthcare workers, treatment providers and policy makers particularly as this relates to evidence informed and targeted harm reduction policies and effective public health interventions

    The Social Network: How People with Visual Impairment use Mobile Phones in Kibera, Kenya

    Living in an informal settlement with a visual impairment can be very challenging resulting in social exclusion. Mobile phones have been shown to be hugely beneficial to people with sight loss in formal and high-income settings. However, little is known about whether these results hold true for people with visual impairment (VIPs) in informal settlements. We present the findings of a case study of mobile technology use by VIPs in Kibera, an informal settlement in Nairobi. We used contextual interviews, ethnographic observations and a co-design workshop to explore how VIPs use mobile phones in their daily lives, and how this use influences the social infrastructure of VIPs. Our findings suggest that mobile technology supports and shapes the creation of social infrastructure. However, this is only made possible through the existing support networks of the VIPs, which are mediated through four types of interaction: direct, supported, dependent and restricted

    Potential for comparative public opinion research in public administration

    Get PDF
    The public administration and public services have always taken a marginal place in the political scientists’ behavioural research. Public administration students on the other hand tend to focus on political and administrative elites and institutions, and largely ignored citizens in comparative research. In this article we make a plea for international comparative research on citizens’ attitudes towards the public administration from an interdisciplinary perspective. Available international survey material is discussed, and main trends in empirical practice and theoretical approaches are outlined, especially those with a potential impact on public sector reform

    What kind of mixed race/ethnicity data is needed for the 2020/21 global population census round: the cases of the UK, USA, and Canada

    Get PDF
    In western countries the mixed race/ethnicity population is experiencing a rapid increase in numbers and growing diversity, raising challenges for its capture in censuses and surveys. Methods include exact combinations of interest, multi-ticking, and open response, as exemplified by the censuses of England and Wales, the USA and Canada, and Scotland and Northern Ireland, respectively. However, investigations of question face validity, reproducibility of findings, and efficacy of capture reveal quality problems with all three approaches. The low reporting reliability of this population urgently requires research and testing to identify optimal strategies. While there is clearly no one gold standard method of capture and current approaches have developed within national contexts, it is timely to review these methods across the three countries and to make recommendations for the upcoming 2020/21 censuses
