Building body identities - exploring the world of female bodybuilders
This thesis explores how female bodybuilders seek to develop and maintain a viable sense of self despite being stigmatized by the gendered foundations of what Erving Goffman (1983) refers to as the 'interaction order'; the unavoidable presentational context in which identities are forged during the course of social life. Placed in the context of an overview of the historical treatment of women's bodies, and a concern with the development of bodybuilding as a specific form of body modification, the research draws upon a unique two year ethnographic study based in the South of England, complemented by interviews with twenty-six female bodybuilders, all of whom live in the U.K. By mapping these extraordinary women's lives, the research illuminates the pivotal spaces and essential lived experiences that make up the female bodybuilder. Whilst the women appear to be embarking on an 'empowering' radical body project for themselves, the consequences of their activity remains culturally ambivalent. This research exposes the 'Janus-faced' nature of female bodybuilding, exploring the ways in which the women negotiate, accommodate and resist pressures to engage in more orthodox and feminine activities and appearances

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

Meaning-Making Practices of Emergent Arabic–English Bilingual Kindergarten Children in Cairo
The number of British Schools in the Middle East and North Africa (MENA) region is growing. The National Curriculum of England is used by an increasing number of such schools. As well as exporting a culturally-specific curriculum, these schools usually adopt an ideology of monolingualism, thus potentially limiting communication for emergent bilinguals and failing to acknowledge the multiple ways of meaning-making.
Current studies of translanguaging are moving the focus to multimodal forms of communication as a resource for thinking and communicating (García and Wei 2014, Wei 2018). Building on the work of Kress (1997, 2010) I explore pre-school emergent bilinguals’ wider signifying practices and create an analytical framework, which I call MMTL (multimodal translanguaging), used as a lens to illustrate meaning-making.
Valley Hill in Cairo, Egypt is a British school which encourages ‘English-only’ as the medium of instruction in the kindergarten. Using a case study methodology, this research explores the meaning-making practices of eight emergent bilingual children aged 3–4 during child-initiated play, later reduced to four in the thesis to provide a detailed multimodal analysis. The principal aim is to explore their speech, gaze, gesture, and their engagement (layout/position) with artefacts during play.
The findings of this study suggest that although there is an ‘English-only’ approach, these young emergent bilingual children are meaning-making in a variety of ways. Children are translanguaging but it is never in isolation from other modes of communication. Emergent bilinguals use a range of modes to mediate their understanding and communication with others. They use gesture, gaze, and artefacts alongside translingual practices to move meaning across to more accessible modes, enabling communication and understanding. The implications for schools should be to embrace such hybrid practices and for teachers to be more responsive to young children’s meaning-making to enable learning
Structure and adsorption properties of gas-ionic liquid interfaces
Supported ionic liquids are a diverse class of materials that have been considered
as a promising approach to design new surface properties within solids for gas
adsorption and separation applications. In these materials, the surface morphology and
composition of a porous solid are modified by depositing ionic liquid. The resulting
materials exhibit a unique combination of structural and gas adsorption properties
arising from both components, the support, and the liquid. Naturally, theoretical and
experimental studies devoted to understanding the underlying principles of exhibited
interfacial properties have been an intense area of research. However, a complete
understanding of the interplay between interfacial gas-liquid and liquid-solid
interactions as well as molecular details of these processes remains elusive.
The proposed problem is challenging and in this thesis, it is approached from
two different perspectives applying computational and experimental techniques. In
particular, molecular dynamics simulations are used to model gas adsorption in films
of ionic liquids on a molecular level. A detailed description of the modeled systems is
possible if the interfacial and bulk properties of ionic liquid films are separated. In this
study, we use a unique method that recognizes the interfacial and bulk structures of
ionic liquids and distinguishes gas adsorption from gas solubility. By combining
classical nitrogen sorption experiments with a mean-field theory, we study how liquid-solid interactions influence the adsorption of ionic liquids on the surface of the porous
support.
The developed approach was applied to a range of ionic liquids that feature
different interaction behavior with gas and porous support. Using molecular
simulations with interfacial analysis, it was discovered that gas adsorption capacity
can be directly related to gas solubility data, allowing the development of a predictive
model for the gas adsorption performance of ionic liquid films. Furthermore, it was
found that this CO2 adsorption on the surface of ionic liquid films is determined by the
specific arrangement of cations and anions on the surface. A particularly important
result is that, for the first time, a quantitative relation between these structural and
adsorption properties of different ionic liquid films has been established. This link
between two types of properties determines design principles for supported ionic
liquids.
However, the proposed predictive model and design principles rely on the
assumption that the ionic liquid is uniformly distributed on the surface of the porous
support. To test how ionic liquids behave under confinement, nitrogen physisorption
experiments were conducted for micro‐ and mesopore analysis of supported ionic
liquid materials. In conjunction with mean-field density functional theory applied to
the lattice gas and pore models, we revealed different scenarios for the pore-filling
mechanism depending on the strength of the liquid-solid interactions.
In this thesis, a combination of computational and experimental studies provides
a framework for the characterization of complex interfacial gas-liquid and liquid-solid
processes. It is shown that interfacial analysis is a powerful tool for studying
molecular-level interactions between different phases. Finally, nitrogen sorption
experiments were effectively used to obtain information on the structure of supported
ionic liquids
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 can’t be proven right. Theologians have the answers that can’t be proven wrong.
Today’s designers of Massively-Multiplayer Online Role-Playing Games create realities for a living. They can’t 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.
That’s today’s designers. Tomorrow’s 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
Interactive Sonic Environments: Sonic artwork via gameplay experience
The purpose of this study is to investigate the use of video-game technology in the design and implementation of interactive sonic centric artworks, the purpose of which is to create and contribute to the discourse and understanding of its effectiveness in electro-acoustic composition highlighting the creative process. Key research questions include: How can the language of electro-acoustic music be placed in a new framework derived from videogame aesthetics and technology? What new creative processes need to be considered when using this medium? Moreover, what aspects of 'play' should be considered when designing the systems? The findings of this study assert that composers and sonic art practitioners need little or no coding knowledge to create exciting applications and the myriad of options available to the composer when using video-game technology is limited only by imagination. Through a cyclic process of planning, building, testing and playing these applications the project revealed advantages and unique sonic opportunities in comparison to other sonic art installations. A portfolio of selected original compositions, both fixed and open are presented by the author to complement this study. The commentary serves to place the work in context with other practitioners in the field and to provide compositional approaches that have been taken
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
Studies on the insecticidal mechanism of Bacillus thuringiensis Vip3A and Cry proteins
El control de plagas y patógenos ha tenido un efecto importante en la mejora del rendimiento de los sistemas agrícolas a nivel mundial. Diferentes tipos de insecticidas químicos se han usado extensivamente durante mucho tiempo para el control de plagas de insectos. Debido a la aparición de resistencias, problemas de contaminación de aguas y problemas de salud humana causados por dichos insecticidas de síntesis, la agricultura moderna necesita una estrategia de gestión integrada de plagas más saludable, respetuosa con el medio ambiente y sostenible. El uso de Bacillus thuringiensis (Bt) y sus proteínas insecticidas para el control de plagas es una de las estrategias biotecnológicas más importantes hasta la fecha. Además, los genes que codifican sus proteínas insecticidas han sido transferidos a plantas, las cuales están siendo utilizadas comercialmente, desde 1996 en gran parte del mundo para el control eficiente de numerosas plagas de insectos. En los últimos años, una nueva subclase de proteínas insecticidas secretables (Vip3) producida durante el crecimiento vegetativo de Bt se ha considerado para la aplicación combinada con las convencionalmente empleadas proteínas Cry, cuya aplicación se ve amenazada por la aparición de poblaciones de insectos resistentes. Las proteínas Vip3 no tienen homología de secuencia con las proteínas Cry y son tóxicas para insectos lepidópteros, sin embargo, su modo de acción todavía no se conoce completamente. En este proyecto de tesis, con el objetivo de mejorar su aplicación en el control biotecnológico de plagas y la comprensión del modo de acción de las proteínas Vip3, se estudiaron diversos aspectos de su actividad insecticida (espectro de acción, resistencia cruzada e interacción con otras proteínas), y se realizó un estudio de los residuos clave para el mantenimiento de la estructura tridimensional y la toxicidad de la proteína Vip3Af mediante mutagénesis dirigida. También analizamos la posible implicación de la unión a receptores en la aparición de resistencia utilizando una cepa resistente que había sido seleccionada con Vip3Aa. En primer lugar, se investigó la toxicidad de 10 toxinas Bt (Cry1Ab, Cry1Ac, Cry1Ah, Cry1Fa, Cry2Aa, Cry2b, Cry1Ie, Vip3Aa19, Vip3Aa16 y Vip3Ca) frente a Mythimna separata (plaga agrícola muy destructiva en Asia y Australia), así como su aplicación combinada mediante bioensayos llevados a cabo en laboratorio. Los resultados mostraron que la concentración letal media LC50 (Cry1Ac/Vip3Aa19/Vip3Ca 3061 veces) se obtuvo rápidamente después de 8 o 9 generaciones de selección en laboratorio. Sin embargo, no se obtuvo resistencia notable seleccionando con Cry1Ab o Cry1F en la misma población y durante el mismo número de generaciones. En un estudio realizado por otros investigadores, también se encontró una respuesta rápida similar a la selección de Vip3Aa en H. virescens, alcanzando un nivel de resistencia > 2300 veces mayor en la décima generación. Es importante hacer notar que esta rápida evolución de la selección en condiciones de laboratorio contrasta con los resultados obtenidos con las proteínas Cry1, tanto en nuestro trabajo como por otros autores: una la población de O. furnacalis adquirió un nivel de resistencia a Cry1Ab de alrededor de 100 veces sólo después de 35 generaciones de selección; de manera similar, una población de O. nubilalis desarrolló una resistencia de más de 3000 veces a Cry1F después de 35 generaciones de selección. Esta diferencia en respuesta a la selección, además de reflejar una frecuencia mucho mayor de alelos de resistencia para Vip3Aa, puede sugerir diferencias en los mecanismos de resistencia a las proteínas Vip3Aa y Cry1, lo cual queda en evidencia cuando se estudia la unión de Vip3A a BBMV de insectos resistentes El análisis de la unión de 125I-Vip3Aa a BBMV de larvas de M. separata tanto de insectos susceptibles y resistentes no reveló ninguna diferencia de unión, ya sea cualitativa o cuantitativa. Los resultados sugieren que la unión alterada a los receptores de la membrana del intestino medio no es el principal mecanismo de resistencia a la proteína Vip3Aa. Numerosos estudios han demostrado que la alteración de los receptores de membrana es un mecanismo evolutivo común que confiere altos niveles de resistencia a las proteínas Cry, pero nunca se ha establecido su relación con la resistencia a Vip3A. Las diferencias de unión cualitativas o c
