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
Victims' Access to Justice in Trinidad and Tobago: An exploratory study of experiences and challenges of accessing criminal justice in a post-colonial society
This thesis investigates victims' access to justice in Trinidad and Tobago, using their own narratives. It seeks to capture how their experiences affected their identities as victims and citizens, alongside their perceptions of legitimacy regarding the criminal justice system. While there have been some reforms in the administration of criminal justice in Trinidad and Tobago, such reforms have not focused on victims' accessibility to the justice system. Using grounded theory methodology, qualitative data was collected through 31 in-depth interviews with victims and victim advocates. The analysis found that victims experienced interpersonal, structural, and systemic barriers at varying levels throughout the criminal justice system, which manifested as institutionalized secondary victimization, silencing and inequality. This thesis argues that such experiences not only served to appropriate conflict but demonstrates that access is often given in a very narrow sense. Furthermore, it shows a failure to encompass access to justice as appropriated conflicts are left to stagnate in the system as there is often very little resolution. Adopting a postcolonial lens to analyse victims' experiences, the analysis identified othering practices that served to institutionalize the vulnerability and powerlessness associated with victim identities. Here, it is argued that these othering practices also affected the rights consciousness of victims, delegitimating their identities as citizens. Moreover, as a result of their experiences, victims had mixed perceptions of the justice system. It is argued that while the system is a legitimate authority victims' endorsement of the system is questionable, therefore victims' experiences suggest that there is a reinforcement of the system's legal hegemony. The findings suggest that within the legal system of Trinidad and Tobago, legacies of colonialism shape the postcolonial present as the psychology and inequalities of the past are present in the interactions and processes of justice. These findings are relevant for policymakers in Trinidad and Tobago and other regions. From this study it is recognized that, to improve access to justice for victims, there needs to be a move towards victim empowerment that promotes resilience and enhances social capital. Going forward it is noted that there is a need for further research
Marvellous real in the Middle East: a comparative study of magical realism in contemporary womenâs fiction
Magical realism has been studied extensively in relation to Latin America and subsequently in other parts of the world, yet the Middle East has not received adequate attention in academic scholarship. This PhD study examines a selection of contemporary female-authored narratives from the Middle East to establish an understanding of the practice of magical realism in this region. The selected texts for this study are: Raja Alemâs Fatma and My Thousand and One Nights; Shahrnush Parsipurâs Women Without Men and Touba and the Meaning of Night; Elif Shafakâs The Bastard of Istanbul and Gina B. Nahaiâs Moonlight on the Avenue of Faith.
This study firstly explores the concept of magical realism as a mode of writing and determines its relationship to the Middle Eastern context. It then evaluates the texts under scrutiny by examining how the narrative of magical realism is constructed and what the sources are of the magical component in these texts, specifically in relation to Middle Eastern mythology. It also investigates the ideological aspect behind the employment of magical realism and whether it serves any political goal. The analysis of the selected texts is approached from three standpoints, that is, from literary, mythological and ideological perspectives. I argue that magical realism serves various purposes and that it is applied from perspectives that can be regarded as marginal to their communitiesâ dominant values, to subvert mainstream ideology. I also demonstrate that the Middle East is a crucial place to investigate magical realism because of the numerous complex cultural values that interact with each other in this region, and which enrich the practice of magical realism
The developing maternal-infant relationship: a qualitative longitudinal study
Aim
The study aimed to explore maternal perceptions and the use of knowledge relating to their infantâs mental health over time using qualitative longitudinal research.
Background
There has been a growing interest in infant mental health over recent years. Much of this interest is directed through the lens of infant determinism, through knowledge regarding neurological development resulting in biological determinism. Research and policy in this field are directed toward individual parenting behaviours, usually focused on the mother. Despite this, there is little attention given to maternal perspectives of infant mental health, indicating that a more innovative approach to methodology is required.
Methods
This study took a qualitative longitudinal approach, and interviews were undertaken with seven mothers from the third trimester of pregnancy and then throughout the first year of the infantâs life. Interviews were conducted at 34 weeks of pregnancy, and then when the infant was 6 and 12 weeks, 6, 9, and 12 months, alongside the collection of researcher field notesâa total of 41 interviews. Data were analysed by creating case profiles, memos, and summaries, and then cross-comparison of the emerging narratives. A psycho-socially informed approach was taken to the analysis of data.
Findings
Three interrelated themes emerged from the data: evolving maternal identity, growing a person, and creating a safe space. The theme of evolving maternal identity dominated the other themes of growing a person and creating a safe space in a way that met perceived socio-cultural requirements for mothering and childcare practices. Participantsâ personal stories give voice to their perceptions of the developing maternal-infant relationship in the context of their socio-cultural setting, relationships with others, and experiences over time.
Conclusions
This study adds new knowledge by giving mothers a voice to express how the maternal-infant relationship develops over time. The findings demonstrate how the developing maternal-infant relationship grows in response to their mutual needs as the mother works to create and sustain identities for herself and the infant that will fit within their socio-cultural context and individual situations. Additionally, the findings illustrate the importance of temporal considerations, social networks, and intergenerational relationships to this evolving process. Recommendations for practice, policy, and education are made that reflect the unique relationship between mother and infant and the need to conceptualise this using an ecological approach

After Creation: Intergovernmental Organizations and Member State Governments as Co-Participants in an Authority Relationship
This is a re-amalgamation of what started as one manuscript and became two when the length proved to be more than any publisher wanted to consider. The splitting consisted of removing what are now Parts 3, 4, and 5 so that the manuscript focused on the outcome-related shared beliefs holding an authority relationship together. Those parts were last worked on in 2018. The rest were last worked on in late 2021 but also remain incomplete.
The relational approach adopted in this study treats intergovernmental organizations and the governments of member states as co-participants in an authority relationship with the governments of their member states. Authority relationships link two types of actor, defined by their authority-holder or addressee role in the relationship, through a set of shared beliefs about why the relationship exists and how the participants should fulfill their respective roles. The IGO as authority holder has a role that includes a right to instruct other actors about what they should or should not do; the governments of member states as addressees are expected to comply with the instructions. Three sets of shared beliefs provide the conceptual âglueâ holding the relationship together. The first defines the goal of the collective effort, providing both the rationale for having the authority relationship and providing a lode star for assessments of the collective effortâs success or lack of success. The second set defines the shared understanding about allocation of roles and the process of interaction by establishing shared expectations about a) the selection process by which particular actors acquire authority holder roles, b) the definitions identifying one or more categories of addressees expected to follow instructions, and c) the procedures through which the authority holder issues instructions. The third set focus on the outcomes of cooperation through the relationship by defining a) the substantive areas in which the authority holder may issue instructions, b) the bases for assessing the relevance actions mandated in instructions for reaching the goal, and c) the relative efficacy of action paths chosen for reaching the goal as compared to other possible action paths.
Using an authority relationship framework for analyzing cooperation through IGOs highlights the inherently bi-directional nature of IGO-member government activity by viewing their interaction as involving a three-step process in which the IGO as authority holder decides when to issue what instruction, the member state governments as followers react to the instruction with anything from prompt and full compliance through various forms of pushback to outright rejection, and the IGO as authority holder responds to how the followers react with efforts to increase individual compliance with instructions and reinforce continuing acceptance of the authority relationship. Foregrounding the dynamics produced by the interaction of these two streams of perception and action reveals more clearly how far intergovernmental organizations acquire capacity to operate as independent actors, the dynamic ways they maintain that capacity, and how much they influence member governmentsâ beliefs and actions at different times. The approach fosters better understanding of why, when, and for how long governments choose cooperation through an IGO even in periods of rising unilateralism
Conscience and Consciousness: British Theatre and Human Rights.
This research project investigates a paradigm of human rights theatre. Through the lens of performance and theatre-making, this thesis explores how we came to represent, speak about, discuss, and own human rights in Britain. My framework of âhuman rights theatreâ proposes three distinctive features: firstly, such works dramatise real-world issues and highlights the role of the state in endangering its citizens; secondly, ethical ruptures are encountered within and without the drama, and finally, these performances characteristically aspire to produce an activist effect on the collective behaviours of the audience.
This thesis interrogates the strategies theatre-makers use to articulate human rights concerns or to animate human rights intent. The selected case-studies for this investigation are ice&fireâs testimonial project, Actors for Human Rights; Badac Theatre; Jonathan Holmesâ work as director of Jericho House; Cardboard Citizensâ youth participation programme, ACT NOW; and Tony Cealyâs Black Menâs Consortium. Deliberately selecting companies and performance events that have received limited critical attention, my methodology constellates case-studies through original interviews, durational observation of creative working methods and proximate descriptions of practice.
The thesis is interested in the experience of coming to âconsciousnessâ through human rights theatre, an awakening to the impacts of rights infringements and rights claiming. I explore consciousness as a processual, procedural, and durational happening in these performance events. I explore the âĂŚffectâ of activist art and examine the ways in which makers of human rights theatre aim to amplify both affective and effective qualities in their work. My thesis also considers the articulation of activist purpose and the campaigning intent of the selected theatre-makers and explores how their activism is animated in their productions. Through the rich seam of discussion generated by the identification and exploration of the traits of a distinctive human rights theatre, I affirm the generative value of this typological enquiry
How to Be a God
When it comes to questions concerning the nature of Reality, Philosophers and Theologians have the answers.
Philosophers have the answers that canât be proven right. Theologians have the answers that canât be proven wrong.
Todayâs designers of Massively-Multiplayer Online Role-Playing Games create realities for a living. They canât spend centuries mulling over the issues: they have to face them head-on. Their practical experiences can indicate which theoretical proposals actually work in practice.
Thatâs todayâs designers. Tomorrowâs will have a whole new set of questions to answer.
The designers of virtual worlds are the literal gods of those realities. Suppose Artificial Intelligence comes through and allows us to create non-player characters as smart as us. What are our responsibilities as gods? How should we, as gods, conduct ourselves?
How should we be gods
The role of adult and community education and training in equipping the youth with employable skills : the case of Mashashane-Maraba area of Limpopo
Youth unemployment is a persistent challenge in South Africa that is worsening as the percentage of especially young people that are unemployed or unemployable increases quarterly. The Province of Limpopo is ranked among rural provinces and is characterised by a significant number of economically-active youth that are either unemployed or unemployable and this has negative effects on families, communities and the nation at large. Of other initiatives, the South African government established Community Education and Training Colleges (CETCs) with an aim to up-skill school-leavers and/or mitigate the high rate of unemployment. This study therefore sought to investigate whether the ACET has up-skilled the youth of Mashashane-Maraba in the Limpopo Province. The study also investigated reasons that explain the low registration in ACET programmes by the youth in Mashashane-Maraba.
An empirical inquiry using a qualitative research design was used to conduct a case study on four Community Learning Centres located in the Mashashane-Maraba area of the Limpopo Province of South Africa. The researcher sourced data from the field through one-on-one face-to-face interviews, focus group discussions, observations and document analysis. The relevant literature was reviewed on the role of ACET in equipping the youth with employable skills. Furthermore, important documents of the Department of Higher Education on ACET relevant to the study were also reviewed to obtain rich data for the study. A sample of 29 participants comprising 20 adult learners, 3 facilitators, 4 centre managers and 2 officials were purposively selected for the interviews from selected Community Education and Training Colleges in Limpopo.
The theories of andragogy, dependency, transformation and empowerment were adopted and used as the foundation of the study. The results revealed that the selected community learning centres in Mashashane-Maraba offered the old general education and training certificate for adult learning programmes however, the programmes did not up-skill or impart skills to students. The fact that the ACET curriculum offered by the CET Colleges did not offer skills training, limits chances of employment to the youth; hence, most of them opted to stay at home rather than enrol for the programme.
Based on the findings, the study made the following recommendations for stakeholders to improve the programmes, especially in the CET Colleges located in the Limpopo Province:
⢠There is a need to provide proper infrastructure for community colleges and their delivery sites in order to foster distinct institutional identity;
⢠The government should incorporate a practical aspect that focuses on imparting job skills in order to enhance employment chances for registered youth. This can reduce the social grant bill on the taxpayers;
⢠The Adult and Community Education and Training (ACET) programmes offered by the selected Community Learning Centres in Limpopo should emphasise on practical skills in order to equip the out-of-school youth with employment or self-employment skills; and
⢠The working conditions of the Community Education and Training Educators should be improved in order to increase their focus and commitment in the provision of skills.
In conclusion, this study contributes to the knowledge in the CET sector by revealing some of the major challenges hindering the effective implementation of curriculum that focus on skills training of unemployed youths in the countryside communities. Given that unemployment is a major problem facing the youth in rural communities, the study emphasised the need for transformation of the curriculum in Community College programmes so that it includes more practical job-related skills such as plumbing, welding, building, electrical and leather works.
The findings from the study could be used to ensure that programmes offered by the CET Colleges up-skill the youth so that their chances of finding employment are enhanced. However, as a case study, this investigation does not seek to over-generalise its findings bearing in mind that the conditions of the various community learning centres (CLCs) may differ from one another.Educational StudiesPh.
