A Decision Support System for Economic Viability and Environmental Impact Assessment of Vertical Farms
Vertical farming (VF) is the practice of growing crops or animals using the vertical dimension via multi-tier racks or vertically inclined surfaces. In this thesis, I focus on the emerging industry of plant-specific VF. Vertical plant farming (VPF) is a promising and relatively novel practice that can be conducted in buildings with environmental control and artificial lighting. However, the nascent sector has experienced challenges in economic viability, standardisation, and environmental sustainability. Practitioners and academics call for a comprehensive financial analysis of VPF, but efforts are stifled by a lack of valid and available data.
A review of economic estimation and horticultural software identifies a need for a decision support system (DSS) that facilitates risk-empowered business planning for vertical farmers. This thesis proposes an open-source DSS framework to evaluate business sustainability through financial risk and environmental impact assessments. Data from the literature, alongside lessons learned from industry practitioners, would be centralised in the proposed DSS using imprecise data techniques. These techniques have been applied in engineering but are seldom used in financial forecasting. This could benefit complex sectors which only have scarce data to predict business viability.
To begin the execution of the DSS framework, VPF practitioners were interviewed using a mixed-methods approach. Learnings from over 19 shuttered and operational VPF projects provide insights into the barriers inhibiting scalability and identifying risks to form a risk taxonomy. Labour was the most commonly reported top challenge. Therefore, research was conducted to explore lean principles to improve productivity.
A probabilistic model representing a spectrum of variables and their associated uncertainty was built according to the DSS framework to evaluate the financial risk for VF projects. This enabled flexible computation without precise production or financial data to improve economic estimation accuracy. The model assessed two VPF cases (one in the UK and another in Japan), demonstrating the first risk and uncertainty quantification of VPF business models in the literature. The results highlighted measures to improve economic viability and the viability of the UK and Japan case.
The environmental impact assessment model was developed, allowing VPF operators to evaluate their carbon footprint compared to traditional agriculture using life-cycle assessment. I explore strategies for net-zero carbon production through sensitivity analysis. Renewable energies, especially solar, geothermal, and tidal power, show promise for reducing the carbon emissions of indoor VPF. Results show that renewably-powered VPF can reduce carbon emissions compared to field-based agriculture when considering the land-use change.
The drivers for DSS adoption have been researched, showing a pathway of compliance and design thinking to overcome the âproblem of implementationâ and enable commercialisation. Further work is suggested to standardise VF equipment, collect benchmarking data, and characterise risks. This work will reduce risk and uncertainty and accelerate the sectorâs emergence
Elite perceptions of the Victorian and Edwardian past in inter-war England
It is often argued by historians that members of the cultivated Elite after 1918 rejected the pre-war past. or at least subjected it to severe denigration. This thesis sets out to challenge such a view. Above all, it argues that inter-war critics of the Victorian and Edwardian past were unable to reject it even if that was what they felt inclined to do. This was because they were tied to those periods by the affective links of memory, family, and the continually unfolding consequences of the past in the present. Even the severest critics of the pre-war world, such as Lytton Strachey, were less frequently dismissive of history than ambivalent towards it. This ambivalence, it is argued, helped to keep the past alive and often to humanise it. The thesis also explores more positive estimation of Victorian and Edwardian history between the wars. It examines nostalgia for the past, as well as instances of continuity of practice and attitude. It explores the way in which inter-war society drew upon aspects of Victorian and Edwardian history both as illuminating parallels to contemporary affairs and to understand directly why the present was shaped as it was. Again, this testifies to the enduring power of the past after 1918. There are three parts to this thesis. Part One outlines the cultural context in which writers contemplated the Victorian and Edwardian past. Part Two explores some of the ways in which history was written about and used by inter-war society. Part Three examines the ways in which biographical depictions of eminent Victorians after 1918 encouraged emotional negotiation with the pas

Co-design As Healing: Exploring The Experiences Of Participants Facing Mental Health Problems
This thesis is an exploration of the healing role of co-design in mental health. Although co-design projects conducted within mental health settings are rising, existing literature tends to focus on the object of design and its outcomes while the experiences of participants per se remain largely unexplored. The guiding research question of this study is not how we design things that improve mental health, but how co-designing, as an act, might do so.
The thesis presents two projects that were organized in collaboration with the mental health charity Islington Mind and the Psychosis Therapy Project (PTP) in London.
The project at Islington Mind used a structured design process inviting participants to design for wellbeing. A case study analysis provides insights on how participants were impacted, summarizing key challenges and opportunities.
The design at PTP worked towards creating a collective brief in an emergent fashion, finally culminating in a board game. The experiences of participants were explored through Interpretative Phenomenological Analysis (IPA), using semi-structured interview data. The analysis served to identify key themes characterising the experience of co-design such as contributing, connecting, thinking and intentioning. In addition, a mixed-methods analysis of questionnaires and interview data exploring participants' wellbeing, showed that all participants who engaged fairly consistently in the project improved after the project ended, although some participants' scores returned to baseline six months later.
Reflecting on both projects, an approach to facilitation within mental health is outlined, detailing how the dimensions of weaving and layered participation, nurturing mattering and facilitating attitudes interlace. This contribution raises awareness of tacit dimensions in the practice of facilitation, articulating the nuances of how to encourage and sustain meaningful and ethical engagement and offering insights into a range of tools. It highlights the importance of remaining reflexive in relation to attitudes and emotions and discusses practical methodological and ethical challenges and ways to resolve them which can be of benefit to researchers embarking on a similar journey.
The thesis also offers detailed insights on how methodologies from different fields were integrated into a whole, arguing for transparency and reflexivity about epistemological assumptions, and how underlying paradigms shift in an interdisciplinary context.
Based on the overall findings, the thesis makes a case for considering design as healing (or a designerly way of healing), highlighting implications at a systems, social and individual level. It makes an original contribution to our understanding of design, highlighting its healing character, and proposes a new way to support mental health. The participants in this study not only had increased their own wellbeing through co-designing, but were also empowered and contributed towards healing the world. Hence, the thesis argues for a unique, holistic perspective of design and mental health, recognizing the interconnectedness of the individual, social and systemic dimensions of the healing processes that are ignited
A narrative study of how shame features in the lives of women living with HIV
Once classed as a devastating virus that resulted in a guaranteed premature death, HIV can be treated successfully with lifelong medication and importantly its transmissibility is eliminated for individuals on effective medication. However, the psychosocial burden of HIV remains for many and despite this advancement in biomedical treatment, HIV remains a highly stigmatised virus and condition.
This study explores how shame features in the experiences of women living with HIV in Ireland. There is an absence of womenâs narratives in the overall discourse on HIV in Ireland, therefore little is known about their lives. Research on shame tells us that prolonged unacknowledged shame can impact on mental well-being if unaddressed.
The studyâs sample comprised twelve women living with HIV who were based in Ireland. Their narratives based on semi-structured interviews have been analysed using Clandinin and Connellyâs (2000) three-dimensional narrative inquiry tool, which explores from the interactional, chronological and situational elements of a story. A cross-case analysis was adopted to explore dominant themes across the twelve narratives.
Findings from this study portray how shame stemmed from an absence of a woman centred HIV narrative and the ongoing presence of stigmatising HIV discourse. Shame featured as three dimensions of the exposed self: anticipated exposure, exposure avoidance and felt exposure. Finally, many of the participants managed to grow through their HIV-related shame and move past it by discovering a shared experience with other women, to reduce emotional isolation.
This study concludes that HIV-related shame can have negative implications for womenâs health and general well-being, thus compromising womenâs ability to live well with HIV. HIV-related shame must be addressed with the appropriate intervention. The study contributes to the development of a women-centred HIV discourse. This can help increase visibility of WLHIV and enable potential mitigation of the onset of HIV-related shame, which is crucial in this era of HIV normalisation
Political Islam and grassroots activism in Turkey : a study of the pro-Islamist Virtue Party's grassroots activists and their affects on the electoral outcomes
This thesis presents an analysis of the spectacular rise of political Islam in Turkey. It has two aims: first to understand the underlying causes of the rise of the Welfare Party which -later became the Virtue Party- throughout the 1990s, and second to analyse how grassroots activism influenced this process. The thesis reviews the previous literature on the Islamic fundamentalist movements, political parties, political party systems and concentrates on the local party organisations and their effects on the party's electoral performance. It questions the categorisation of Islamic fundamentalism as an appropriate label for this movement. An exploration of such movements is particularly important in light of the event of 11`x' September. After exploring existing theoretical and case studies into political Islam and party activism, I present my qualitative case study. I have used ethnographic methodology and done participatory observations among grassroots activists in Ankara's two sub-districts covering 105 neighbourhoods. I examined the Turkish party system and the reasons for its collapse. It was observed that as a result of party fragmentation, electoral volatility and organisational decline and decline in the party identification among the citizens the Turkish party system has declined. However, the WP/VP profited from this trend enormously and emerged as
the main beneficiary of this process. Empirical data is analysed in four chapters, dealing with the different aspects of the Virtue Party's local organisations and grassroots activists. They deal with change and continuity in the party, the patterns of participation, the routes and motives for becoming a party activist, the profile of party activists and the local party organisations. I explore what they do and how they do it. The analysis reveals that the categorisation of Islamic fundamentalism is misplaced and the rise of political Islam in Turkey cannot be explained as religious revivalism or the rise of Islamic fundamentalism. It is a political force that drives its strength from the urban poor which has been harshly affected by the IMF directed neoliberal economy policies. In conclusion, it is shown that the WP/VP's electoral chances were significantly improved by its very efficient and effective party organisations and highly committed grassroots activists
Chinese Benteng Womenâs Participation in Local Development Affairs in Indonesia: Appropriate means for struggle and a pathway to claim citizenâ right?
It had been more than two decades passing by aftermath the devastating Asiaâs Financial Crisis in 1997, subsequently followed by Suhartoâs step down from his presidential throne which he occupied for more than three decades. The financial turmoil turned to a political disaster furthermore has led to massive looting that severely impacted Indonesians of Chinese descendant, including unresolved mystery of the most atrocious sexual violation against women and covert killings of students and democracy activists in this country. Since then, precisely aftermath May 1998, which publicly known as âReformasiâ1, Indonesia underwent political reform that eventually corresponded positively to its macroeconomic growth. Twenty years later, in 2018, Indonesia captured worldwide attention because it has successfully hosted two internationally renowned events, namely the Asian Games 2018 â the most prestigious sport events in Asia â conducted in Jakarta and Palembang; and the IMF/World Bank Annual Meeting 2018 in Bali. Particularly in the IMF/World Bank Annual Meeting, this event has significantly elevated Indonesiaâs credibility and international prestige in the global economic powerplay as one of the nations with promising growth and openness. However, the narrative about poverty and inequality, including increasing racial tension, religious conservatism, and sexual violation against women are superseded by friendly climate for foreign investment and eventually excessive glorification of the nationâs economic growth. By portraying the image of promising new economic power, as rhetorically promised by President Joko Widodo during his presidential terms, Indonesia has swept the growing inequality in this highly stratified society that historically compounded with religious and racial tension under the carpet of digital economy.Arte y Humanidade
Masculinities, vulnerability and negotiated identity: Understanding the reporting behaviours of men who experience violence or otherwise harmful behaviour, within a sex work context
Context The focus of sex work related discussions most commonly falls on female providers of sexual services, and male purchasers. As a result, the often victim-oriented policy response in England and Wales falls short of truly addressing the needs of men who are involved in the sale of sex, with there being limited support available for them and a systemic approach which does not fully recognise the potential for men to face harm within this context. Methods The aim of this study is to explore experiences of and reactions to violence, and otherwise harmful behaviours, faced by men in the context of their sex working, by understanding the lived realities of a sample of men who engage in this type of work. The study takes a phased approach which combines an initial informative quantitative survey, with three subsequent phases of semi-structured interviews with male sex workers, sex work-focused practitioners and police officers. The method is guided by feminist research principles which suggest that reality is situated within those with lived experience, and also by an element of co-creation which has grounded this study within the perspectives of male sex workers from its conception. Findings The findings of this research suggest that all of the men involved in the study had faced at least one of the violent or otherwise harmful behaviours outlined, though reporting of these behaviours was not at all common. Discussions with the male sex working participants, practitioners and the police highlighted the issues related to the structural influences of authority, such as the police, and the social environment, and the internalisation of these wider factors, which create barriers to reporting for groups such as male sex workers and others who face similar social marginalisation. Conclusions This study challenges existing gendered understandings of violence and otherwise harmful behaviour within a sex work context, by highlighting the harmful experiences of men. By exploring these experiences and the reporting behaviours of those involved, the study also proposes a new framework for understanding barriers to reporting, which suggests that these are formed through the influences of formal and informal measures of social control, and the internalisation of these outside influences by the individual. By better understanding the experiences of men, and the barriers to their reporting, this study attempts to nuance a gendered discussion. Within, I propose that in order to better support male sex workers, responses must begin by appreciating the heterogeneity of those involved in sex work and the influence of their individual circumstances and the social environment on their willingness to seek support
The Caribbean Syzygy: a study of the novels of Edgar Mittelholzer and Wilson Harris
The problem of racial inheritance - the "search for identity" - is a recurring theme in the criticism of Caribbean literature. It is a pre-occupation with Caribbean writers, affecting both subject matter and literary quality, as FM. Birbalsingh, for example, has shown with reference to the novels of John Hearne and E,R. Braithwaite (Caribbean quarterly Vols. 14, December 1968 and 16, March 1970). This study of the work of Edgar Mittelholzer and Wilson Harris will attempt to show that there are important areas still to be explored relating Caribbean literature to its complex racial and cultural background. Both Mittelholzer and Harris deserve close, critical study in their own right; but a parallel examination reveals similarities and differences which bring into sharper focus wider concerns of Caribbean literature. The two important directions of West Indian writing are more clearly seen: the one, pioneered by Mittelholzer, in which the writer looks outward towards a "parent" culture, and the other looking inward, seeking in its own, complex inheritance the raw material for new and original growth. Mittelholzer and Harris are both Guyanese of mixed racial stock, both deeply concerned with the psychological effects of this mixture, and both writers have a profound awareness of the Guyanese historical and cultural heritage. They also share a deep feeling for the Guyenese landscape which appears in their work as a brooding presence affecting radically -the lives of those who live within i-t. Mittelholzer's attitude to his mixed racial and cultural origins, however, produces in his work a schizophrenic Imbalance while Harris, by accepting racial and cultural complexity as a starting-point, initiates a uniquely creative and experimental art. Mittelholzer, in his approach to history, human character eM landscape, remains a vi "coastal" writer never really concerned (as Harris is) with. the deeper significance of the "Interior" and all that this implies, both in a geographical and psychological sense. The fact that Mittelbolzer's work reflects a psychological imbalance induced by a pre-occupation with racial identity has been demonstrated by Denis Williams in the 1968 Mittelholzer Lectures, and by Joyce Sparer in a series of articles in the Guyana Graphic. Mittelholzer's awareness of this imbalance, however, and his attempt to come to terms with it in his art remain to be examined and documented, as does Harris's attempt to create am "associative" art aimed at healing the breach in the individual consciousness of Caribbean Man. The aim of this study is to demonstrate that Mitteholzer and. Harris, although antithetical in impact and style (each representing an approach to fiction directly opposed to the other) are, in fact, the opposite elements of a dichotomy. Their work illustrates the negative and positive aspects of the racial and cultural schizophrenia of the Caribbean, for both writers in their different ways are preoccupied with (and therefore have embodied in their work) the juxtaposition and, contrasting of apparently irreconcilable emotional and intellectual qualities - the Caribbean Syzygy
âHow can you have music therapy without humour?!â: a phenomenologically informed arts-based reflexive study exploring humour in music therapy with persons living with dementia
In music therapy practice, humour is closely linked to playfulness and play and is largely taken for granted by music therapists. Despite music therapistsâ anecdotal interest, to date there has been little in-depth focus on humour in music therapy work. The two main studies written in the English language address the use of humour and its musical form and are positioned from music therapistsâ perspectives. Thus, a need was identified for including the views of persons attending music therapy, along with more comprehensive study of relational experiences and therapeutic consequences of humour.
A pilot phase of this study showed humour as relationally significant and invited the development of novel methods with which to investigate it. Subsequently, a phenomenologically informed reflexive-relational methodology was used to better understand 1. How humour enables contact in music therapy with persons living with dementia and 2. How music therapists perceive, embody and experience humour in music therapy. Interpretative methods of âinterview-encountersâ with persons living with dementia and their music therapists, and focus groups with music therapists, were used to gather data and arts-based reflexive methods of sense-making offered imaginal understanding of relational experiences of humour.
Familiar verbal, non-verbal and embodied forms of humour, or âin-jokesâ, were found to act as catalysts for intrapersonal and interpersonal contact between music therapists and persons living with dementia. These moments appeared to heighten experiences of presence in relation to self and other. In addition, contact through humour enabled a relational equality that was meaningful as well as individually agential.
From music therapistsâ perspectives, a tension was found between humour and a sense of professional identity and role in practice. This appeared to lead to anxiety when using or engaging with humour and meant that a sense of relational risk was embodied in performing humour in practice. The music therapists involved in the study had absorbed this sense of risk bodily through experiences of improvising with others whilst training. Important questions were therefore raised around the âtool-nessâ of humour which also surfaced implicit power dynamics in music therapy relationships.
Framing a sense of humour as a developmentally vital relational experience, this study suggests that a more sophisticated understanding of humour in music therapy is needed. This has broad implications for considering music therapy processes, pedagogy and practice
Living with churches in the Borders: mission and ministry in rural Scottish parish churches
Is there a sustainable future for mission and ministry in rural Scottish parish churches?
In this thesis I use autoethnographic fieldwork within practical theology to understand and respond to the challenges and opportunities facing parish churches in rural contexts in Scotland.
My research investigates the lived realities of two rural parish churches in the Scottish Borders over twenty-seven months of immersive fieldwork. It engages with existing research on rural churches along with broader discussions of congregational studies, church renewal and missiology, recognising the dearth of existing research into rural Presbyterian churches in Scotland. Throughout my thesis I use a combination of ethnographic âthickâ description, autoethnographic reflexivity and critical theological reflection to evaluate the sustainability of current models of mission and ministry as a foundation for discussions of possibilities for the future.
My thesis acknowledges the unsustainability of traditional clergy dependent models of rural ministry and argues that a creative and sustainable future is possible if churches are willing to embrace a process of faithful change. I use the Five Marks of Mission as a framework for developing a rural missiology, arguing that rural parish churches have the potential to engage in embodied, creative missional practice as worshiping communities in rural Scotland. I conclude by addressing specific challenges facing the Church of Scotland in 2021, using the lens of rural experience to offer practical insight in looking towards the future
