The impact of enterprise social networking on knowledge sharing between academic staff in higher education
This thesis was submitted for the award of Doctor of Philosophy and was awarded by Brunel University LondonHigher education institutions have always considered knowledge sharing critical for research excellence and finding proper methods for sharing knowledge across academic staff has therefore been a major issue for universities and knowledge management research. Recent evidence shows that many universities have embraced enterprise social networking tools to improve communication, relationships, partnerships, and knowledge sharing. To date, there is little understanding of the critical factors for online knowledge sharing behaviour between academic staff, and the impact of these factors on work benefits for academic staff which differ between consumptive users and contributive users in higher education. This study employed the extended unified theory of acceptance and use of technology (UTAUT) to examine factors affecting knowledge sharing about the consumptive use and contributive use of enterprise social network (ESN) behaviour. The study adopts a critical realism philosophical approach and employed a grounded theory mixed methods. The conceptual model was validated through structural equation modelling based on an online survey of 254 academic staff using enterprise social networking as a part of their work in the United Kingdom. The findings have significant theoretical and practical implications for researchers and policy makers. The research has developed a cohesive ESN use model by extending and modifying the unified theory of acceptance and use of technology. The findings indicate significant differences around factors affecting consumptive and contributive usage patterns within ESNs. Due to advances in communication technologies, this research argues that a previous model suggested by Venkatesh et al. (2003) is no longer fit for purpose and the new communication tools can lead to improved knowledge in higher education. This research also makes valuable contributions to universities from a managerial viewpoint, suggesting that universities could help their scholars find a more comprehensive range of funding sources matching scholars' ideas
Digital Decisions and Online Heritage: an Examination of the Response of the GLAM Sector to the Opportunities of the Internet Since 2000
The digitisation of a critical mass of heritage collections has been an aspiration for successive UK governments and the heritage sector since the year 2000, with the stated aim of reaching new unserved audiences and thereby democratising heritage. But analysis shows that only an estimated 8.5% of the UK’s collections have been digitised and shared with the public. This research argues that there is a gap between what the UK Government believes is the purpose and value of digitisation and that expressed within the heritage discourse, and that this has been a barrier to digitisation. It examines predictions made during the years 1997-2003, a time when digitisation was being widely debated, and identifies three themes: Digital death and Obsolescence (fears linked to the speed of technological change), Ownership and the Public/Private web (the benefits and threats of sharing collections online) and Authority and Democratisation (the sharing of the curatorial role with visitors and the notion that digitisation can democratise heritage). Interviews with digital heritage professionals reveal they believe cost, time and copyright concerns to have been the main barriers to digitisation. I show that these practical challenges have been exacerbated by external pressures: technological, economic and social but predominantly political. The 2018 DCMS Culture is Digital report identifies the main barrier as a lack of digital maturity, but I argue this could equally be described as a lack of business maturity. I conclude that mass digitisation is unlikely to be a priority for heritage unless it can be successfully monetised, but that the Covid-19 crisis has created a new focus on this. I recommend that heritage organisations should take the lead from commercially successful museums like the Rijksmuseum in the Netherlands, which has successfully digitised almost its entire collection and shared it with no restrictions. I recommend that if the government wants to professionalise the sector, it needs to give British heritage organisations the same creative and financial freedom the Rijksmuseum has enjoyed. For UK heritage organisations, I recommend that a culture of open sharing might prove to be the key to democratising heritage, while at the same time helping them to discover the value and purpose of digitisation

Interdisciplinarity in the Age of the Triple Helix: a Film Practitioner's Perspective
This integrative chapter contextualises my research including articles I have published as well as one of the creative artefacts developed from it, the feature film The Knife That Killed Me. I review my work considering the ways in which technology, industry methods and academic practice have evolved as well as how attitudes to interdisciplinarity have changed, linking these to Etzkowitz and Leydesdorff’s ‘Triple Helix’ model (1995). I explore my own experiences and observations of opportunities and challenges that have been posed by the intersection of different stakeholder needs and expectations, both from industry and academic perspectives, and argue that my work provides novel examples of the applicability of the ‘Triple Helix’ to the creative industries. The chapter concludes with a reflection on the evolution and direction of my work, the relevance of the ‘Triple Helix’ to creative practice, and ways in which this relationship could be investigated further
Ethnographically-informed distributed participatory design framework for sociotechnical change : co-designing a collaborative training tool to support real-time collaborative writing
Although Wikipedia’s immense success is partially due to its support of the asynchronous collaboration model, researchers argue that the bureaucratic rules and technical infrastructure enabling it feed into Wikipedia’s content bias. Attempts to introduce different collaboration models have so far failed, but the fact that they have occurred persistently over time suggests that at least part of the Wikipedia community favours incorporating features such as real-time collaborative editing.
My research is founded on the argument that the advantageous aspects of the asynchronous model should be preserved, although the existing model needs to be complemented by real-time collaboration in settings such as Wikipedia training events. This thesis describes a Participatory Design process resulting in a prototype called WikiSync, a system that introduces real-time collaboration for the Wikipedia community using a responsible design approach that is respectful of Wikipedia’s rich social structure and history.
Furthermore, my research has produced an adaptive methodology for co-designing sociotechnical solutions in a geographically distributed community. After an in-depth observation of online Wikipedia training and the existing community innovation processes, my participatory design sessions have helped create a mutual learning environment for co-designing WikiSync in tandem with the community, while addressing a wide range of their concerns about real-time collaboration. I also consulted the broader Wikipedia community using an online social ideation and voting tool to evaluate the desirability and applicability of the solution. Finally, the resulting ethnographically-informed distributed Participatory Design framework provides an innovation process for involving a diverse, widely distributed online community in co-designing sociotechnical solutions
Challenges and perspectives of hate speech research
This book is the result of a conference that could not take place. It is a collection of 26 texts that address and discuss the latest developments in international hate speech research from a wide range of disciplinary perspectives. This includes case studies from Brazil, Lebanon, Poland, Nigeria, and India, theoretical introductions to the concepts of hate speech, dangerous speech, incivility, toxicity, extreme speech, and dark participation, as well as reflections on methodological challenges such as scraping, annotation, datafication, implicity, explainability, and machine learning. As such, it provides a much-needed forum for cross-national and cross-disciplinary conversations in what is currently a very vibrant field of research
Training future hybrid nonprofit social enterprise leaders: a research-based instructional needs analysis
Nonprofit social enterprises (NSEs) seek to address societal problems through for-profit ventures. Because they pursue social and commercial goals, these organizations have great potential to solve social and environmental issues more efficiently and effectively. Given their unique purpose and challenges, NSEs require a different type of leadership than traditional nonprofit organizations, a distinctive competency model with specialized social work and business management training. Research has shown, however, that finding leaders with this necessary mix for effective management poses a challenge for such organizations. This exploratory study aimed to examine the extent to which MPA (i.e., master’s degree in public administration) and MNM (i.e., master’s degree in nonprofit management) preparatory programs include the primary NSE leadership competencies in their curricula. The researcher developed an NSE leadership competency survey from the literature and distributed it to 250 MPA and MNM faculty and administrators employed at various public and private universities. Data analysis techniques included descriptive statistics, t tests, and bivariate correlations, showing neither program type focuses strongly on teaching NSE leadership competencies. MNM programs and private universities cover several well and more extensively than MPA programs and public universities. Findings highlight pedagogical enhancement opportunities for MPA and MNM NSE leadership preparation programs at public and private universities
