An exploration of the language within Ofsted reports and their influence on primary school performance in mathematics: a mixed methods critical discourse analysis
This thesis contributes to the understanding of the language of Ofsted reports, their similarity to one another and associations between different terms used within ‘areas for improvement’ sections and subsequent outcomes for pupils. The research responds to concerns from serving headteachers that Ofsted reports are overly similar, do not capture the unique story of their school, and are unhelpful for improvement. In seeking to answer ‘how similar are
Ofsted reports’ the study uses two tools, a plagiarism detection software (Turnitin) and a discourse analysis tool (NVivo) to identify trends within and across a large corpus of reports.
The approach is based on critical discourse analysis (Van Dijk, 2009; Fairclough, 1989) but shaped in the form of practitioner enquiry seeking power in the form of impact on pupils and practitioners, rather than a more traditional, sociological application of the method.
The research found that in 2017, primary school section 5 Ofsted reports had more than half of their content exactly duplicated within other primary school inspection reports published that same year. Discourse analysis showed the quality assurance process overrode variables such as inspector designation, gender, or team size, leading to three distinct patterns of duplication: block duplication, self-referencing, and template writing. The most unique part of a report was found to be the ‘area for improvement’ section, which was tracked to externally verified outcomes for pupils using terms linked to ‘mathematics’. Those
required to improve mathematics in their areas for improvement improved progress and attainment in mathematics significantly more than national rates. These findings indicate that there was a positive correlation between the inspection reporting process and a beneficial impact on pupil outcomes in mathematics, and that the significant similarity of one report to another had no bearing on the usefulness of the report for school improvement purposes

A Design Science Research Approach to Smart and Collaborative Urban Supply Networks
Urban supply networks are facing increasing demands and challenges and thus constitute a relevant field for research and practical development. Supply chain management holds enormous potential and relevance for society and everyday life as the flow of goods and information are important economic functions. Being a heterogeneous field, the literature base of supply chain management research is difficult to manage and navigate. Disruptive digital technologies and the implementation of cross-network information analysis and sharing drive the need for new organisational and technological approaches. Practical issues are manifold and include mega trends such as digital transformation, urbanisation, and environmental awareness.
A promising approach to solving these problems is the realisation of smart and collaborative supply networks. The growth of artificial intelligence applications in recent years has led to a wide range of applications in a variety of domains. However, the potential of artificial intelligence utilisation in supply chain management has not yet been fully exploited. Similarly, value creation increasingly takes place in networked value creation cycles that have become continuously more collaborative, complex, and dynamic as interactions in business processes involving information technologies have become more intense.
Following a design science research approach this cumulative thesis comprises the development and discussion of four artefacts for the analysis and advancement of smart and collaborative urban supply networks. This thesis aims to highlight the potential of artificial intelligence-based supply networks, to advance data-driven inter-organisational collaboration, and to improve last mile supply network sustainability. Based on thorough machine learning and systematic literature reviews, reference and system dynamics modelling, simulation, and qualitative empirical research, the artefacts provide a valuable contribution to research and practice
Inovação, empreendedorismo e desenvolvimento económico em África: Uma abordagem pós-positivista e "topo da pirâmide" para Moçambique
Esta tese desenvolve uma investigação abrangente sobre o empreendedorismo africano, revisitando o seu quadro concetual tradicional e posicionando-o enquanto elemento fundamental das estratégias de desenvolvimento para a África Subsariana (ASS). Explorados os diferentes impactos do empreendedorismo de oportunidade e do empreendedorismo de necessidade na região, efetuou-se uma pesquisa sobre a situação dos vários países da ASS que participaram no Global Entrepreneurship Monitor na última década, com vista a compor o status quo hipotético do empreendedorismo regional, ao qual juntámos um estudo empírico original e com elementos metodológicos inovadores sobre a atividade empreendedora em Moçambique. O alcance das estratégias empreendedoras implementadas na ASS é avaliado através de um estudo dos polos africanos de inovação tecnológica e do empreendedorismo digital que neles tem vindo recentemente a emergir, a que juntámos um levantamento original do tech hub de Maluana. Por fim, a partir destes casos e de uma leitura política das opções económicas do estado moçambicano com impacto sobre o ecossistema empreendedor, desenvolve-se uma proposta de teoria da mudança, numa lógica pós-positivista, para suportar medidas de política pública desejáveis para a eclosão de um empreendedorismo de “topo da pirâmide” em Moçambique.This thesis develops a comprehensive investigation of African entrepreneurship, revisiting its traditional conceptual framework and positioning it as a fundamental element in development strategies for Sub-Saharan Africa (SSA). Exploring the different impacts of opportunity entrepreneurship and necessity entrepreneurship in the region, an analysis was carried out on the situation of the various SSA countries that participated in the Global Entrepreneurship Monitor in the last decade, with a view to composing the hypothetical status quo of the entrepreneurship in the region, to which we added an original empirical study with innovative methodological elements on entrepreneurial activity in Mozambique. The reach of entrepreneurial strategies implemented in the SSA is assessed through a study of the African tech hubs, or innovation hubs, and the digital entrepreneurship that has recently emerged there, to which we have added an original survey of the Maluana tech hub. Finally, based on these cases and on a political reading of the economic options of the Mozambican government with an impact on the entrepreneurial ecosystem, a proposal for a theory-of-change is developed, within a post-positivist approach, to support desired public policy measures for the emergence of a “top of the pyramid” entrepreneurship in Mozambique
Co-designing age-friendly neighborhood spaces in Copenhagen: Starting with an age-friendly co-design process
Age-friendly cities and communities are currently attracting much attention as the ageing population becomes a larger proportion of our societies and their needs and aspirations become more diverse, which needs to be reflected in our cities. This calls for older people to play an active role in the design of suitable environments, e.g., by being involved in the design process. With this paper, we present a study where the methodology of co-design was used to engage 100+ older people in a low-income neighborhood in Copenhagen in designing new neighborhood spaces to reflect their needs and wishes. By focusing on the co-design process, and not the design solution, we investigate and present insights across the entire span of the process—from recruitment to implementation—and seek to extract particular elements that contribute to the age friendliness of the process. Recommendations for future co-design processes with older people include focusing on explicit communication and foreseeable steps to create a process that offers multiple and flexible participation options and to upgrade the latter stages of the co-design process through scale 1:1 prototyping and implementation. The findings contribute to both the professional practice of co-designing with older people on a spatial scale, as well as to policy makers and practice stakeholders when initiating initiatives with age-friendly cities and communities
Augmented classification for electrical coil winding defects
A green revolution has accelerated over the recent decades with a look to replace existing transportation power solutions through the adoption of greener electrical alternatives. In parallel the digitisation of manufacturing has enabled progress in the tracking and traceability of processes and improvements in fault detection and classification. This paper explores electrical machine manufacture and the challenges faced in identifying failures modes during this life cycle through the demonstration of state-of-the-art machine vision methods for the classification of electrical coil winding defects. We demonstrate how recent generative adversarial networks can be used to augment training of these models to further improve their accuracy for this challenging task. Our approach utilises pre-processing and dimensionality reduction to boost performance of the model from a standard convolutional neural network (CNN) leading to a significant increase in accuracy

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
Applications of higher-form symmetries at strong and weak coupling
In this thesis we consider two distinct applications of higher-form symmetries in quantum field theory. First we explore the spontaneous breaking of higher-form symmetry in a holographic quantum field theory containing matter fields in the fundamental representation of the gauge group U(N). At strong coupling, we numerically solve the bulk equations of motion to compute the current-current Green’s function and demonstrate the existence of a goldstone mode. We then compare to direct analytic perturbative results obtained at weak coupling. In the second half of the thesis we work with a hydrodynamic effective field theory which possesses a higher-form symmetry. In particular, we consider a natural higher-derivative correction to force-free electrodynamics and compute a hydrodynamic transport coefficient from microscopics. Concretely, this is a perturbative QED calculation in a background magnetic field. Finally we compare our findings to astrophysical observations
