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
EVALUACIÓN ANALGÉSICA PERIOPERATORIA DEL ACETAMINOFÉN EN PERRAS SOMETIDAS A OVARIOHISTERECTOMÍA ELECTIVA
Tesis de doctorado que evalúa el efecto analgésico del acetaminofén en perras ovarihisterectomizadas.La administración de analgésicos antiinflamatorios no esteroidales (AINES) para el control del
dolor post-quirúrgico en perros es una práctica común, debido a sus efectos analgésicos,
antiinflamatorios y antipiréticos. En el presente trabajo se realizaron dos estudios. En el
experimento 1, el objetivo fue evaluar la analgesia post-operatoria del acetaminofén
(paracetamol) a través de la utilización de las escalas de reconocimiento clínico del dolor
DIVAS (Escala Dinámica e Interactiva Analógica Visual) y UMPS (Escala de la Universidad
de Melbourne), en perras sometidas a ovariohisterectomía electiva. Además de valorar la
seguridad y eficacia clínica del uso del acetaminofén en perros mediante pruebas de
funcionamiento hepático y renal en el post-operatorio inmediato. Para ello, se utilizaron 30
perras de diferentes razas que fueron asignadas aleatoriamente a uno de los tres grupos de
tratamiento: acetaminofén [GACET; n=10, 15 mg kg-1 intravenoso (IV)], carprofeno (GCARP;
n=10, 4 mg kg-1 IV) y meloxicam (GMELOX; n=10, 0.2 mg kg-1 IV). Todos los tratamientos se
administraron 30 minutos antes de la cirugía y posterior a esta durante 48 horas. En este período
el acetaminofén se administró por vía oral cada 8 horas (15 mg kg-1); el carprofeno (4 mg kg-1)
y el meloxicam (0.1 mg kg-1) se administraron por vía IV cada 24 horas. Durante el
postoperatorio, los sistemas de puntuación del dolor DIVAS y UMPS fueron medidos a las 1,
2, 4, 6, 8, 12, 16, 20, 24, 36 y 48 horas post-cirugía. Para evaluar la seguridad clínica de los
tratamientos, se recolectaron muestras de sangre de la vena yugular para realizar la medición de
enzimas ALT, AST, ALP, y los metabolitos bilirrubina directa, bilirrubina indirecta, bilirrubina
total, creatinina, urea, albúmina y glucosa. Esto fue realizado en T0 (pre-anestesia; TBASAL), 48
y 96 horas después de la cirugía (T48, T96). Los resultados indican que en la evaluación clínica
del dolor de todos los grupos de estudio, hubo una reducción gradual en la percepción del mismo
durante el postoperatorio en ambos sistemas de puntuación; no obstante, también fue observado
que ninguna escala difirió significativamente entre los tres grupos de tratamiento (P>0.05) en
cada momento de evaluación durante las 48 horas post-cirugía. En cuanto a los parámetros
bioquímico séricos, sólo la ALT aumentó significativamente en T96 en el GACET y GCARP con
respecto a los valores basales (P<0.01). El resto de los analitos séricos evaluados se mantuvo
en rangos normales. En el experimento 2 bajo el mismo diseño experimental de tratamientos
administrados, el objetivo fue evaluar el efecto analgésico perioperatorio del acetaminofén
2
administrado pre y post-quirúrgicamente en perras sometidas a ovariohisterectomía electiva a
través de la medición del índice de la actividad del tono parasimpático (PTA). Este parámetro
hemodinámico fue medido 60 minutos antes de la cirugía (TBASAL) y durante el transquirúrgico
en la aplicación de estímulos nociceptivos: colocación de las pinzas de campo backhouse
(TPINZ), incisión de piel y abordaje quirúrgico primario (TINC), ligadura y extracción de pedículo
ovárico izquierdo (TOVI) y derecho (TOVD), ligadura y transfixión del cuello uterino (TLIGUT),
sección quirúrgica del cuello uterino (TCUT), reconstrucción de peritoneo y planos anatómicos
musculares (TMUSC) y sutura de piel (TSUT). Durante el postoperatorio, el índice PTA fue
valorado a las 1, 2, 4, 6, 8, 12, 16, 20, 24, 36 y 48 horas, en los mismos tiempos en que fueron
evaluadas las escalas de reconocimiento de dolor DIVAS y UMPS. Los resultados obtenidos en
la medición del índice PTA basal para GACET fue 65 ± 8, para GCARP 65 ± 7 y para GMELOX 62 ±
5. Durante los diferentes tiempos transquirúrgicos, los valores promedio de índice PTA indican
que GACET (76 ± 14) y GMELOX (72 ± 18) muestran tendencia a manifestar mayores niveles en
comparación con GCARP (62 ± 13) desde el inicio del procedimiento quirúrgico sin que esto
pudiera comprobarse estadísticamente, ya que no hubo diferencias significativas entre grupos
de tratamiento ni entre los tiempos quirúrgicos evaluados (P>0.05). En el postoperatorio, el
índice PTA fue de 65 ± 9 en el GACET, 63 ± 8 en el GCARP y 65 ± 8 en el GMELOX. Los resultados
tampoco mostraron diferencias estadísticamente significativas con los valores basales o entre
los tratamientos (P>0.05). El índice PTA postoperatorio mostró una sensibilidad del 40%,
especificidad del 98.46% y valor predictivo negativo del 99.07% con respecto a la escala
validada de UMPS. En conclusión, el acetaminofén puede considerarse una herramienta para el
tratamiento efectivo del dolor perioperatorio agudo en perros, ya que mostró la misma eficacia
clínica que el meloxicam y el carprofeno para la analgesia postquirúrgica en perras sometidas a
ovariohisterectomía electiva. Además, la evidencia del uso de este medicamento no condujo a
reacciones adversas o cambios en los parámetros evaluados, lo que indica su seguridad clínica.
Finalmente, destacar que el índice PTA representa una medición objetiva del comfort y
analgesia postoperatoria, por lo que es una herramienta que podría ayudar a predecir las
respuestas hemodinámicas asociadas con el dolor

Appendix A Characterization survey (104), Appendix B. EFL Students’ questionnaire (109), Appendix C. Characterization survey: data treatment question (113), Appendix D. Informed consent letter, English version (114), Appendix E. Carta de consentimiento informado, versión en español (117), Appendix F. Time Schedule (120), Appendix G. Sample Challenges at Moodle (126), Appendix H. Participants’ questionnaire results (128).La gamificación es un término que suele denotar el uso de componentes del juego en situaciones no relacionadas con el juego en sí para crear experiencias de aprendizaje agradables, divertidas y motivadoras para los estudiantes (Werbach y Hunter, 2012). Por lo tanto, el análisis de los factores básicos de los juegos se convierte en algo esencial a la hora de definir y utilizar la gamificación como estrategia de mediación del inglés como lengua extranjera para fortalecer rasgos específicos de pronunciación en los estudiantes de pregrado de la UPTC Sogamoso.
El procedimiento de estudio se basa en la investigación acción mediante la implementación de la estrategia de gamificación para la mediación en la pronunciación del inglés, orientada a treinta estudiantes de diferentes programas de ingeniería, administración y tecnología con niveles heterogéneos de dominio del inglés. Las actividades se centran principalmente en la producción de sonidos, el ritmo, el acento y la entonación, los rasgos de pronunciación segmental y suprasegmental.
Los resultados arrojaron una evidente mejora en las características segméntales y suprasegmentales de la percepción en la pronunciación de los participantes así como la contribución del objetivo de los juegos a la instrucción fonética y fonológica, la sensación en el juego a la motivación para mejorar la pronunciación, el reto establecido en los juegos a la actitud positiva de los participantes, y la sociabilidad a la exposición practica de la pronunciación inglesa.Gamification is a relatively new term that often denotes the use of game components in situations unrelated to the game itself to create enjoyable, fun, and motivating learning experiences for students (Werbach and Hunter, 2012). Therefore, analyzing the games' basic factors becomes essential when defining and using gamification as a strategy for English as Foreign Language mediation to strengthen specific pronunciation features in UPTC Sogamoso undergraduate students.
The study procedure is based on action research by implementing the gamification strategy for mediation in English pronunciation, oriented to thirty students from different engineering, management, and technology programs at heterogeneous levels of English proficiency. The activities mainly focus on sound production, rhythm, stress, and intonation, segmental and suprasegmental pronunciation features.
The results showed an evident improvement in the segmental and suprasegmental features of the participants' pronunciation perception as well as the contribution of game goals to phonetics and phonological instruction, the game sensation to the motivation for pronunciation improvement, the game challenge to the participants' positive attitude, and the sociality to the English pronunciation exposure practice

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

The interpretation of Islam and nationalism by the elite through the English language media in Pakistan.
The media is constructed and interpreted through what people 'know'. That knowledge is, forthe most part, created through day to day experiences. In Pakistan, Islam and nationalism aretwo components of this social knowledge which are intrinsically tied to the experiences of thePakistani people. Censorship and selection are means through which this knowledge isarticulated and interpreted.General conceptions of partially shared large scale bodies of knowledge and ideas reinforce,and are reinforced by, general medium of mass communication: the print and electronic media.Focusing on the govermnent, media institutions and Pakistani elites, I describe and analyse thedifferent, sometimes conflicting, interpretations of Islam and Pakistani nationalism manifest inand through media productions presented in Pakistan.The media means many things, not least of which is power. It is the media as a source ofpower that is so frequently controlled, directed and manipulated. The terminology may beslightly different according to the context within which one is talking - propaganda, selection,etc. - but ultimately it comes down to the same thing - censorship. Each of the three groups:government, media institutions and Pakistani elites - have the power to interpret and censormedia content and consideration must be taken of each of the other power holders consequentlyrestricting the power of each group in relation to the other two. The processes of thismanipulation and their consequences form the major themes of this thesis
Exploring the effects of spinal cord stimulation for freezing of gait in parkinsonian patients
Dopaminergic replacement therapies (e.g. levodopa) provide limited to no response for axial motor symptoms including gait dysfunction and freezing of gait (FOG) in Parkinson’s disease (PD) and Richardson’s syndrome progressive supranuclear palsy (PSP-RS) patients. Dopaminergic-resistant FOG may be a sensorimotor processing issue that does not involve basal ganglia (nigrostriatal) impairment. Recent studies suggest that spinal cord stimulation (SCS) has positive yet variable effects for dopaminergic-resistant gait and FOG in parkinsonian patients. Further studies investigating the mechanism of SCS, optimal stimulation parameters, and longevity of effects for alleviating FOG are warranted. The hypothesis of the research described in this thesis is that mid-thoracic, dorsal SCS effectively reduces FOG by modulating the sensory processing system in gait and may have a dopaminergic effect in individuals with FOG. The primary objective was to understand the relationship between FOG reduction, improvements in upper limb visual-motor performance, modulation of cortical activity and striatal dopaminergic innervation in 7 PD participants. FOG reduction was associated with changes in upper limb reaction time, speed and accuracy measured using robotic target reaching choice tasks. Modulation of resting-state, sensorimotor cortical activity, recorded using electroencephalography, was significantly associated with FOG reduction while participants were OFF-levodopa. Thus, SCS may alleviate FOG by modulating cortical activity associated with motor planning and sensory perception. Changes to striatal dopaminergic innervation, measured using a dopamine transporter marker, were associated with visual-motor performance improvements. Axial and appendicular motor features may be mediated by non-dopaminergic and dopaminergic pathways, respectively. The secondary objective was to demonstrate the short- and long-term effects of SCS for alleviating dopaminergic-resistant FOG and gait dysfunction in 5 PD and 3 PSP-RS participants without back/leg pain. SCS programming was individualized based on which setting best improved gait and/or FOG responses per participant using objective gait analysis. Significant improvements in stride velocity, step length and reduced FOG frequency were observed in all PD participants with up to 3-years of SCS. Similar gait and FOG improvements were observed in all PSP-RS participants up to 6-months. SCS is a promising therapeutic option for parkinsonian patients with FOG by possibly influencing cortical and subcortical structures involved in locomotion physiology
