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

The influence of blockchains and internet of things on global value chain
Copyright © 2022 The Authors. Despite the increasing proliferation of deploying the internet of things (IoT) in the global value chain (GVC), several challenges might lead to a lack of trust among value chain partners, for example, technical challenges (i.e., confidentiality, authenticity, and privacy); and security challenges (i.e., counterfeiting, physical tampering, and data theft). In this study, we argue that blockchain technology (BT), when combined with the IoT ecosystem, will strengthen GVC and enhance value creation and capture among value chain partners. Therefore, we examine the impact of BT combined with the IoT ecosystem and how it can be utilized to enhance value creation and capture among value chain partners. We collected data through an online survey, and 265 U.K. Agri-food retailers completed the survey. Our data were analyzed using structural equation modeling. Our finding reveals that BT enhances GVC by improving IoT scalability, security, and traceability combined with the IoT ecosystem. Moreover, the combination of BT and IoT strengthens GVC and creates more value for value chain partners, which serves as a competitive advantage. Finally, our research outlines the theoretical and practical contribution of combining BT and the IoT ecosystem
Embodying entrepreneurship: everyday practices, processes and routines in a technology incubator
The growing interest in the processes and practices of entrepreneurship has
been dominated by a consideration of temporality. Through a thirty-six-month
ethnography of a technology incubator, this thesis contributes to extant
understanding by exploring the effect of space. The first paper explores how
class structures from the surrounding city have appropriated entrepreneurship
within the incubator. The second paper adopts a more explicitly spatial analysis
to reveal how the use of space influences a common understanding of
entrepreneurship. The final paper looks more closely at the entrepreneurs within
the incubator and how they use visual symbols to develop their identity. Taken
together, the three papers reject the notion of entrepreneurship as a primarily
economic endeavour as articulated through commonly understood language and
propose entrepreneuring as an enigmatic attractor that is accessed through the
ambiguity of the non-verbal to develop the ‘new’. The thesis therefore contributes
to the understanding of entrepreneurship and proposes a distinct role for the non-verbal in that understanding
A productive response to legacy system petrification
Requirements change. The requirements of a legacy information system change, often in unanticipated ways, and at a more rapid pace than the rate at which the information system itself can be evolved to support them. The capabilities of a legacy system progressively fall further and further behind their evolving requirements, in a degrading process termed petrification. As systems petrify, they deliver diminishing business value, hamper business effectiveness, and drain organisational resources. To address legacy systems, the first challenge is to understand how to shed their resistance to tracking requirements change. The second challenge is to ensure that a newly adaptable system never again petrifies into a change resistant legacy system. This thesis addresses both challenges. The approach outlined herein is underpinned by an agile migration process - termed Productive Migration - that homes in upon the specific causes of petrification within each particular legacy system and provides guidance upon how to address them. That guidance comes in part from a personalised catalogue of petrifying patterns, which capture recurring themes underlying petrification. These steer us to the problems actually present in a given legacy system, and lead us to suitable antidote productive patterns via which we can deal with those problems one by one. To prevent newly adaptable systems from again degrading into legacy systems, we appeal to a follow-on process, termed Productive Evolution, which embraces and keeps pace with change rather than resisting and falling behind it. Productive Evolution teaches us to be vigilant against signs of system petrification and helps us to nip them in the bud. The aim is to nurture systems that remain supportive of the business, that are adaptable in step with ongoing requirements change, and that continue to retain their value as significant business assets
Balancing the urban stomach: public health, food selling and consumption in London, c. 1558-1640
Until recently, public health histories have been predominantly shaped by medical and scientific perspectives, to the neglect of their wider social, economic and political contexts. These medically-minded studies have tended to present broad, sweeping narratives of health policy's explicit successes or failures, often focusing on extraordinary periods of epidemic disease viewed from a national context. This approach is problematic, particularly in studies of public health practice prior to 1800. Before the rise of modern scientific medicine, public health policies were more often influenced by shared social, cultural, economic and religious values which favoured maintaining hierarchy, stability and concern for 'the common good'. These values have frequently been overlooked by modern researchers. This has yielded pessimistic assessments of contemporary sanitation, implying that local authorities did not care about or prioritise the health of populations. Overly medicalised perspectives have further restricted historians' investigation and use of source material, their interpretation of multifaceted and sometimes contested cultural practices such as fasting, and their examination of habitual - and not just extraordinary - health actions. These perspectives have encouraged a focus on reactive - rather than preventative - measures.
This thesis contributes to a growing body of research that expands our restrictive understandings of pre-modern public health. It focuses on how public health practices were regulated, monitored and expanded in later Tudor and early Stuart London, with a particular focus on consumption and food-selling. Acknowledging the fundamental public health value of maintaining urban foodways, it investigates how contemporaries sought to manage consumption, food production waste, and vending practices in the early modern City's wards and parishes. It delineates the practical and political distinctions between food and medicine, broadly investigates the activities, reputations of and correlations between London's guild and itinerant food vendors and licensed and irregular medical practitioners, traces the directions in which different kinds of public health policy filtered up or down, and explores how policies were enacted at a national and local level. Finally, it compares and contrasts habitual and extraordinary public health regulations, with a particular focus on how perceptions of and actual food shortages, paired with the omnipresent threat of disease, impacted broader aspects of civic life

Studies of strategic performance management for classical organizations theory & practice
Nowadays, the activities of "Performance Management" have spread very broadly in actually every part of business and management. There are numerous practitioners and researchers from very different disciplines, who are involved in exploring the different contents of performance management. In this thesis, some relevant historic developments in performance management are first reviewed. This includes various theories and frameworks of performance management. Then several management science techniques are developed for assessing performance management, including new methods in Data Envelopment Analysis (DEA) and Soft System Methodology (SSM). A theoretical framework for performance management and its practical procedures (five phases) are developed for "classic" organizations using soft system thinking, and the relationship with the existing theories are explored. Eventually these results are applied in three case studies to verify our theoretical development. One of the main contributions of this work is to point out, and to systematically explore the basic idea that the effective forms and structures of performance management for an organization are likely to depend greatly on the organizational configuration, in order to coordinate well with other management activities in the organization, which has seemingly been neglected in the existing literature of performance management research in the sense that there exists little known research that associated particular forms of performance management with the explicit assumptions of organizational configuration. By applying SSM, this thesis logically derives some main functional blocks of performance management in 'classic' organizations and clarifies the relationships between performance management and other management activities. Furthermore, it develops some new tools and procedures, which can hierarchically decompose organizational strategies and produce a practical model of specific implementation steps for "classic" organizations. Our approach integrates popular types of performance management models. Last but not least, this thesis presents findings from three major cases, which are quite different organizations in terms of management styles, ownership, and operating environment, to illustrate the fliexbility of the developed theoretical framework
Vulnerability, decision-making and the protection of prisoners in Scotland and England
Vulnerable and protection prisoners currently make up a sizeable proportion of the prison populations in England and Scotland, and designated physical space to house them, an approach that has developed significantly in both countries since the 1960s, remains under studied. Within research on prisons, vulnerability has been predominantly associated with risks to the self, for example, mental health problems, self-harm and suicide, internal vulnerabilities that prisoners either bring into an establishment or which are a consequence of the stressors of prison life. This literature further tends to focus on certain categories of prisoner, namely those who have committed sexual crimes. This framing of vulnerability in prison means academic research typically studies vulnerability as a settled status, and there has been a move away from exploring meanings, experiences and determinations of vulnerability as these arise and change at different points of a person’s journey through prison. This study addresses these gaps by sharing the perspectives directly from those at risk of victimization in prison as well as from those in charge of deciding who will get protection from risks. The focus is on prisoner and staff decisions to relocate to protective housing (vulnerable prisoner units (VPU) in England and protection halls in Scotland).
This research utilised qualitative methods, interviewing staff (13) involved in designating or managing vulnerability in prison as well as prisoners (23) who had been identified as needing protective housing. The research was conducted in one prison in England and two prisons in Scotland. It highlights the significant levels of victimization, trauma and fear experienced by prisoner research participants, and in doing so complicates prevailing ideas of vulnerability in prison. The findings chapters show: staff perspectives on what counts as a valid basis of vulnerability and therefore how it is managed and to some extent rationed (Chapter 5); the importance of journeys into and through prisons which shape and intensify experiences of vulnerability (Chapter 6); the perspectives of prisoners housed in a VPU in England which reinforced the idea that vulnerability is fluid and that there are some common factors affecting decisions to relocate from mainstream wings, but ultimately each decision is situated in the personal circumstances of an individual (Chapter 7); the perspectives of prisoners housed in protection halls in Scotland highlighting the factors that influence decisions to seek out or resist protective accommodation where, like England, common factors influenced decisions but were situated in highly individual circumstances (Chapter 8), and how these feelings were managed. The conclusion (Chapter 9) summarises key findings and calls for a sociology of the vulnerable prisoner (building on a conceptualisation of vulnerability in Chapter 3) to understand not only how they navigate risk from others and the prison itself, but how they make sense of their newly acquired yet further stigmatized identity. Finally, it sets out some implications and suggestions for policy based on its new contribution to a sociology of vulnerability
Scalable software and models for large-scale extracellular recordings
The brain represents information about the world through the electrical activity of
populations of neurons. By placing an electrode near a neuron that is firing (spiking), it
is possible to detect the resulting extracellular action potential (EAP) that is transmitted
down an axon to other neurons. In this way, it is possible to monitor the communication
of a group of neurons to uncover how they encode and transmit information. As the
number of recorded neurons continues to increase, however, so do the data processing
and analysis challenges. It is crucial that scalable software and analysis tools are developed
and made available to the neuroscience community to keep up with the large
amounts of data that are already being gathered.
This thesis is composed of three pieces of work which I develop in order to better
process and analyze large-scale extracellular recordings. My work spans all stages of extracellular
analysis from the processing of raw electrical recordings to the development
of statistical models to reveal underlying structure in neural population activity.
In the first work, I focus on developing software to improve the comparison and adoption
of different computational approaches for spike sorting. When analyzing neural
recordings, most researchers are interested in the spiking activity of individual neurons,
which must be extracted from the raw electrical traces through a process called
spike sorting. Much development has been directed towards improving the performance
and automation of spike sorting. This continuous development, while essential,
has contributed to an over-saturation of new, incompatible tools that hinders rigorous
benchmarking and complicates reproducible analysis. To address these limitations, I
develop SpikeInterface, an open-source, Python framework designed to unify preexisting
spike sorting technologies into a single toolkit and to facilitate straightforward
benchmarking of different approaches. With this framework, I demonstrate that modern,
automated spike sorters have low agreement when analyzing the same dataset, i.e.
they find different numbers of neurons with different activity profiles; This result holds
true for a variety of simulated and real datasets. Also, I demonstrate that utilizing a
consensus-based approach to spike sorting, where the outputs of multiple spike sorters
are combined, can dramatically reduce the number of falsely detected neurons.
In the second work, I focus on developing an unsupervised machine learning approach
for determining the source location of individually detected spikes that are
recorded by high-density, microelectrode arrays. By localizing the source of individual
spikes, my method is able to determine the approximate position of the recorded neuriii
ons in relation to the microelectrode array. To allow my model to work with large-scale
datasets, I utilize deep neural networks, a family of machine learning algorithms that
can be trained to approximate complicated functions in a scalable fashion. I evaluate
my method on both simulated and real extracellular datasets, demonstrating that it is
more accurate than other commonly used methods. Also, I show that location estimates
for individual spikes can be utilized to improve the efficiency and accuracy of spike
sorting. After training, my method allows for localization of one million spikes in approximately
37 seconds on a TITAN X GPU, enabling real-time analysis of massive
extracellular datasets.
In my third and final presented work, I focus on developing an unsupervised machine
learning model that can uncover patterns of activity from neural populations
associated with a behaviour being performed. Specifically, I introduce Targeted Neural
Dynamical Modelling (TNDM), a statistical model that jointly models the neural activity
and any external behavioural variables. TNDM decomposes neural dynamics (i.e.
temporal activity patterns) into behaviourally relevant and behaviourally irrelevant dynamics;
the behaviourally relevant dynamics constitute all activity patterns required
to generate the behaviour of interest while behaviourally irrelevant dynamics may be
completely unrelated (e.g. other behavioural or brain states), or even related to behaviour
execution (e.g. dynamics that are associated with behaviour generally but are not
task specific). Again, I implement TNDM using a deep neural network to improve its
scalability and expressivity. On synthetic data and on real recordings from the premotor
(PMd) and primary motor cortex (M1) of a monkey performing a center-out reaching
task, I show that TNDM is able to extract low-dimensional neural dynamics that are
highly predictive of behaviour without sacrificing its fit to the neural data
To be or not to be: a critical realist exploration of factors motivating doctors in their commitment to improve their teaching practice in a clinical setting in Oman
Adopting a critical realist framework, this study explored how medical doctors come to understand and espouse, or resist, their roles as teachers in clinical settings and how they seek to become more proficient in that role. This work builds on earlier research on doctors’ professional development as teachers and extends it into the particular cultural context of medical practice and education in the Sultanate of Oman. A qualitative approach was adopted. Data were collected in 2016 through semi-structured in-depth interviews with 27 senior clinicians and by the examination of relevant institutional policy documents. Interviews were conducted in two hospital settings: the Sultan Qaboos University Hospital (SQUH) and the Royal Hospital (RH), which is a Ministry of Health Hospital (MoHH).
The findings suggest that Omani medical doctors’ orientation to their roles as teachers and their understanding of their responsibility to prepare the next generation of medical professionals have been transformed by three main events over the last 3 decades. First was the establishment of Sultan Qaboos University College of Medicine and Health Sciences (CoMHS) in 1986. Next came the governmental authorities’ decision to train medical doctors in the overseas hospitals that have structured postgraduate clinical training since the 1990s. Thus, while the senior doctors contributing to this study had received some or all of their medical training outside of Oman, they were helping to build a medical education system which sought to raise the next generations of doctors at home. Finally came the establishment of the Oman Medical Speciality Board (OMSB) in 2006 as the official body responsible for the graduate medical education in Oman. However, due to a lack of clear policy regarding their teaching roles, the Ministry of Health (MoH) doctors felt that they, as compared to their colleagues in the university teaching hospital (SQUH), were being expected to make an extra effort to teach in their clinical setting. All respondents, whether recruited from RH or SQUH, recognised the influence their own experience of being taught had on their personal development as clinical teachers on their return to Oman. Respondents’ exposures to different teaching and learning cultures and styles contributed to their motivation to teach and learn about teaching. In particular, many respondents believed that the religious culture of the country contributed to a pervasive attitude of altruism in the orientation of doctors to both their patients and their students.
However, demotivators such as the health system’s hierarchical structure, unclear educational roles, lack of resources—time, human and suitable facilities—for teaching in their hospitals are significant challenges in accomplishing their multiple roles and developing themselves for their educational roles. What emerged as a fundamental challenge for the RH respondents was the lack of any clear policy regarding the doctor’s role as a teacher. The respondents believed that having a clear policy would empower the doctors and give them the support they need for their multiple roles in the clinical setting. Such policy would also guide the administrators and decision-makers in the support and resourcing that they provide to doctors, which they believed were so essential to ensure the next generation of doctors developed according to Oman’s mission and vision.
This study’s findings show clearly the need to establish and standardise national medical education policy and procedures for the MoH doctors, thus giving them a clarity of roles and responsibilities they believe to exist for their SQUH colleagues. Having such national standards and policy is an essential part of a health organisation, and hence its implication for the doctors will be to provide them with the road map for the day-to-day management of their multiple complex roles. It is also clear that the Ministry of Health and the educational institutions (governmental and private at both the undergraduate and the postgraduate levels) need to collaborate and cooperate to establish an integrated medical education system for clinical settings, not just for the learners but also for the doctors who teach them, and thus to establish a stable teaching and learning environment. The presence of such a national policy for medical education will have a positive impact upon the quality of medical education, patient care, and upon junior doctors’ willingness to pursue careers as medical educators in clinical settings
