The chemistry and magnetism of some rhenium and rhodium perovskite oxides

This work focuses on synthesis and characterisation of novel 4d and 5d materials with attention given to spin, orbital and lattice effects seen in metal oxides with heavy transition-metals.
The first half of the work is devoted to topochemical reduction of rhenium-containing perovskites following from the work on double perovskites with the composition Sr2BB’O6 (B = 4d/5d; B’ = 3d), that exhibit spin-polarisation and ferromagnetism. An attempt was made to make Re5+/6+ phases via low temperature methods to overcome synthetic challenges of cited phases. Treatment of Sr2ReLiO6 with 5%/95% H2/N2 gas resulted in formation of Sr2Re6+LiO5.5, a cation ordered double perovskite with partial oxygen vacancy ordering localised on alternate layers of a tetragonal perovskite unit cell. The phase showed extensive crystallographic twinning to minimize lattice strain built as a result of unusual vacancy positions. The phase showed high spin-orbit coupling effects despite the breakage of local Re symmetry. Following this, B’-site doped Sr2ReLi0.64Co0.36O6 was treated with dilute hydrogen gas to form Sr2ReLi0.64Co0.36O5.5, a solid-solution of Re5+, Re6+, Co2+, and Li1+ with oxygen vacancies distributed across the lattice in a disordered manner. This experiment confirmed that inclusion of Li can stabilise the 5d-3d metal oxide systems for topochemical reduction.
The second half is devoted to the study of electric transport and magnetic properties of mixed-metal rhodium perovskite oxides. It is shown that La0.5Sr0.5Mn0.5Rh0.5O3 crystallizes in the Pnma space group with Rh and Mn distributed evenly in the B-site to form a solid-solution. Electric transport measurements show Mott’s Variable Range Hopping behavior across the whole temperature range but magnetic measurements show a transition to a ferromagnetic state at TC = 55 K suggesting ferromagnetic insulator type behavior. A study of structural and physical properties concludes the cations are found in Mn3+ and Rh4+ oxidation states and the ferromagnetism is a result of superexchange interactions between Mn3+ – Mn3+ centers with Rh4+ cations not involved in ferromagnetic exchange. A’-site doping with Ca2+ to make La0.5Sr0.5-xCaxMn0.5Rh0.5O3 (x = 0.15, 0.25) shows expected changes to unit cell parameters including decrease in volume, bending of the B-O-B angle, and a decrease in TC. The synthesis of the Ruddlesden-Popper analogue La0.5Sr1.5Mn0.5Rh0.5O4 is studied in detail and shown to crystallize in the I4/mmm space group when made in air but with phase separation due to oxygen inhomogeneity. Treating the anion deficient phases under flowing oxygen gas restores the stoichiometry. Finally the synthesis and characterisation of B-site disordered spin-glass La0.5Sr0.5Fe0.5Rh0.5O3 with the Fe3+ and Rh4+ oxidation state combination confirms the relative stability of Rh4+ over the generally accepted Rh3+ oxidation state.

Comparative legal reasoning in strict liability

The imposition of strict liability has long been and remains highly controversial. Legal systems rely on it to different extents and the arguments which are used to justify its imposition vary considerably within and across jurisdictions. The thesis compares the main justifications for strict liability as put forward in four legal systems, two common law (England and the United States) and two civil law (France and Italy). After explaining how strict liability is understood in the four laws and setting out the relevant contexts of strict liability, the thesis analyses comparatively the treatment that legal arguments receive across these legal systems. Some of these arguments are based on the notion of risk, while others relate to goals such as the avoidance of accidents, the protection of victims, or the redistribution of losses. By looking at how these arguments are used in each of the four legal systems, the thesis unearths a wide variety of patterns of reasoning, which reflect the different ways in which legal actors across the four laws think about strict liability. Moreover, the thesis assesses the justificatory weight of the arguments, showing that these can assume varying significance within and across the four laws and that such variations reflect different views as to the values and goals which should guide strict liability and inspire tort law more generally. Overall, the thesis seeks to improve our understanding of strict liability, to shed light on the significance and role of the justifications put forward for its imposition, and to enhance our comprehension of the different legal cultures featuring in the four legal systems studied.

Thailand during World War II: Impact and aftermath

Japan coordinated its invasion of Thailand to coincide with the 7 December 1941 attack on Pearl Harbour. Small and with little choice, Thailand quickly joined the Axis. Despite this capitulation, Japanese occupation brought substantial economic loss and widespread social disruption. GDP contracted by a fifth. Japanese finance required that Thailand pay the costs of occupation and ship goods, mostly rice, to Japan while receiving little in return. Resulting shortages of consumer goods, swift money supply expansion and high inflation cut living standards, necessitated rationing and led to social unrest.
One main aim of my dissertation is to analyse the costs to Thailand of Japanese occupation. The dissertation’s other main objective is to examine the longer-term impact of occupation. Alone in Southeast Asia, post-World War II Thailand avoided revolution or civil war. The advantages of administrative continuity through occupation, buoyant rice exports and a non-strategic geographical location largely explain post-war stability. Furthermore, the wartime alliance with Japan avoided Thailand’s population being taken as comfort women or as forced labour on the Thailand-Burma railway.
Wartime macro-economic shocks helped to shape Thailand’s post-1945 economic development. Efforts towards industrialisation and import substitution were a response to wartime setbacks: the government directed resources towards producing goods which were scarce during the occupation. In reaction to wartime fiscal dislocation, the state strengthened its control of financial institutions, budgets, and currency. Exploring the connection between Thai experiences under the Japanese and during the early 1950s is crucial to fully understanding the legacies of the war.

Increasing police trust through normative alignment

In this thesis, I examine the challenges that police encounter in building public trust. An action research design utilises community engagement in two U.S. communities to discern the values and behaviours that generate trust in the police and to explore how those values may be integrated into policing policies and processes. While there is general agreement that compliance emanates from the practice of the principles of procedural justice which are interrelated with trust, normative alignment, and legitimacy, it has proven to be to more difficult to test, translate, and embed these ideas in police organisations. With these factors in mind, I tested a process to increase trust and normative alignment between the community and police and to answer the primary question: How can police trust and legitimacy be increased? I conducted four phases of qualitative research and document analysis to determine which values community members desire in police officers, how police organisations can align their values with the community’s values, how to select police officers who possess the community’s values, and how police organisations can reinforce the community’s values in their officers.
I used focus groups, interviews, and document retrieval to gather the data and used content analysis, word coding, crosstabulation, curriculum mapping, and gap analysis to analyse the data. The results show that trust from community members can be increased if police officers are first characterised by Cultural Competence, Servant Leadership, Emotional Intelligence, and High Character and then trained in the legal and technical skills necessary for the fulfilment of their policing duties. In other words, hire for character and train for competence. I also discuss definitions of a ‘good police officer’, compliance, procedural justice, trust, normative alignment, legitimacy, organisational considerations, and police officer selection.

Skills that predict reading in Korean primary school children at year 2

The present study explored the relationship between reading comprehension and the following predictors: vocabulary, phonological awareness and rapid automatized naming (RAN). It is acknowledged that decoding skills exert an important influence in early reading while language skills take its place in later stages. However, the majority of studies on the predictors of reading comprehension have focused on children learning to read English, a deep orthography. Accumulated evidence on the development of reading comprehension in orthographies other than English suggest that underpinning reading skills may develop at a different pace for children learning to read Korean, a language with a highly transparent orthography and unique alphabet.
Forty-eight children in Year 2 were sampled from three schools in the suburbs of Taegu, South Korea. The children were assessed on reading comprehension, receptive vocabulary, phonological awareness and rapid automatized naming (RAN). Nonverbal intelligence and age in months were used as a covariate. It was hypothesized that if results of the data analyses showed vocabulary to be as important, or more important, than phonological awareness in predicting reading comprehension, it would suggest that decoding skills are reaching a ceiling and language skills are starting to exert an important influence on reading comprehension for the Korean children.
Results of the multiple regression analyses showed that vocabulary and phonological awareness had an equal effect in predicting reading comprehension scores, respectively explaining 15.8% and 13.3% of added variance after nonverbal intelligence and age in months had been controlled for. Rapid automatized naming did not have a significant predictive effect on reading comprehension with any of the statistical models. The findings support the emergence of oral language skills as an important determinant of early reading comprehension in Korean. The equal importance of phonological awareness suggests that phonological principles are of universal importance for early reading, regardless of the simplicity of the orthography. The findings of the effect of RAN added to the discrepancies in the literature.

How does the use of a geographic information system (GIS) engender spatial thinking in Year 8 geography students?

This research investigates the impact of using a geographic information system (GIS) on students’ spatial thinking. This was done through the design and implementation of two GIS-based schemes of work. Collaboration took place through the planning and teaching of both interventions to Year 8 geography students. This small-scale evaluation used qualitative methods to investigate students’ and collaborators’ views. Student work was also analyzed using a framework developed for the assessment of spatial thinking skills. The findings suggest that the use of a GIS does enhance, and in most cases improves students’ spatial thinking skills, but, that spatial thinking as a skill is hard to quantify and difficult to measure progress in. Another benefit that using a GIS affords the reflective practitioner is the creation of engaging, contemporary and interactive lessons, using real data, from which Year 8 students derive a lot of geographical value.

The post-mortal condition: being with the dead in the age of digital media

The dead are increasingly present on the web. Within the next three decades alone, an estimated 2.2 billion people will die, many leaving behind a considerable volume of data, commonly referred to as digital remains. Despite the societal significance of this development, existing literature has mainly focused on lived experience, leaving macro-level concerns largely unexplored and under-theorised. As a first step in addressing this lacuna, the present thesis sets out to identify and critically interrogate the macro-ethical challenges that arise from the accumulation of digital remains. This objective is pursued in five distinct studies. The first two propose a critical framework to understand the ethically undesirable consequences of commercial and ideological interests in the management of digital remains. The following two studies use statistical modelling to project the accumulation of digital remains throughout the 21st century, and then identify a number of ethical risks associated with their curation. The last study provides an in-depth interrogation of the concept of presence as it relates to past individuals and digital technology, and unpacks some of the ethical implications. The integration of these five studies, I argue, illustrates the emergence of a new mode of being with the dead — referred to as the post-mortal condition — whereby the deceased are no longer separated from, but maintain a personal presence within, the domains of the living. I argue that this presence is more than merely a private matter for the bereaved. It is ultimately a concern for all of society — future, past, and present. Consequently, the challenge before us is to develop technological, regulatory, and economic systems that place the good of all humanity, rather than merely the share currently alive, at its centre.

Burnout in medicine: A novel approach exploring the impact of uncertainty and the use of biomarkers as a measurement tool

Burnout constitutes a significant challenge for healthcare organisations not only in respect to individual wellbeing but also in terms of the catastrophic downstream implications to patient safety, patient satisfaction, and quality of care. This DPhil, divided into three parts, aims to explore burnout in healthcare professionals, an accelerating phenomenon that is hotly discussed but minimally understood, with a focus on the impact uncertainty has and an exploration into the novel use of neurohormones as potential biomarkers of wellbeing.
Part I: Exploration of concepts: burnout and uncertainty.
Chapter 1 presents a selective overview of the broad context of burnout in healthcare, reporting existing literature on the impact of burnout—to physicians, to patients, and to healthcare organisations—and considering the challenges that pertain to burnout research, particularly relating to challenges in measurement. Chapter 2 explores the presence of uncertainty in the healthcare environment looking at what impacts an individual’s tolerance of uncertainty and how the reaction affects provider- and patient-centred outcomes. Chapters 3 and 4 present two observational studies exploring drivers of satisfaction at work for faculty in an academic medical centre, with an analysis of the interplay between burnout and uncertainty in the clinical environment. Chapter 5 presents a study that looks at how language used in clinical hand-over affects sense of uncertainty in the receiving clinician, demonstrating how language variation can influence emotional perception of uncertainty.
Part II: Exploration of biology: exploration into use of biomarkers to measure burnout.
Chapters 6 and 7 explore the novel use of cortisol and oxytocin levels as potential biomarkers of stress and burnout in clinical faculty at a large teaching hospital.
Part III: Exploration of interventions to reduce burnout and strategies to embrace uncertainty.
Chapter 8 presents an interprofessional intervention study looking to reduce burnout through self-facilitated groups meeting monthly for three months. This study re-affirms the importance of the findings presented in this thesis and points to the need for more interventions aimed at enhancing trainee and faculty wellbeing. Chapter 9 synthesises current literature on tolerance of uncertainty alongside findings of the thesis, self-experience, and experience of colleagues and students in a narrative review to identify strategies to help clinicians thrive in the face of clinical uncertainty.
Finally, Chapter 10 presents an overview of the key findings from each study, their methodological strengths and limitations, directions for future research, and implications for clinical training, the measurement of wellbeing initiatives, and patient care.

France and Japan, 1850-1885 : an assessment of French influence and diplomacy

This thesis studies the encounter of France and Japan over a period of thirty-five years, during which Japanese influence on France was marginal, limited to artistic circles in Paris, whereas French influence in Japan was considerable.
By European standards Japan in the 1850s was a backward, feudal, and isolated country. Japan, unlike almost every other nation in Asia, was not colonised, Yet it would have seemed preposterous in the 1850s to imagine that Japan would become one of the world’s major powers. However, following the opening of the country in 1854, Japan experiences a major transformation that touches every aspect if its society.
The forces that propelled Japan into the modern world were indigenous, nonetheless in this transformation, Western influence and models were significant determining factors. Although the Japanese government at one time or another employed foreign instructors from numerous countries (including Holland, Italy, Switzerland, Belgium, Russia, Sweden, Austria, China, Korea and Canada), the four Western countries which were to have the greatest impact were Great Britain, France, Germany and the United States.

Touch in late medieval English theatre

This thesis examines touch in late medieval English theatre, considering tactile encounters on stage and the role of touch in audience experience. Although touch is increasingly attracting attention in medieval studies, theatre has thus far been an exception to this trend. To rectify this, I focus primarily—though not exclusively—on biblical drama, especially the York and N-Town Plays. My methodology is threefold, synthesizing lexical analysis, interdisciplinary comparisons of drama and art, and materially informed readings of medieval theatre.
At the heart of this thesis lies a paradox in medieval understandings of touch that has hitherto gone unnoticed: the sense of touch offered a pathway to the sacred, but it was also a source of uncleanness. Medieval plays—precisely because they involved human bodies—were ideally positioned to interrogate this paradox on stage. Further, some medieval plays put their spectators in a position to experience the touch paradox first hand. However, from the 1530s onwards, the sacred half of the medieval touch paradox was in decline. This development was also reflected on the contemporary stage.
The introduction provides a review of existing scholarship, defines my corpus and terminology, outlines my methodology, and advances my theory of the medieval touch paradox. Here, I also introduce a leitmotif for the thesis as a whole: Doubting Thomas, the apostle who refused to believe in Christ’s Resurrection without tangible proof. Chapters one and two explore moments of touch on the medieval stage in relation to the themes of gender and religious difference respectively. The remaining three chapters explore the tactile aspects of audience experience, focusing respectively on the eyes, the hands, and the feet as agents of touch.
The conclusion explores the wider implications of my thesis for medieval studies. In brief, this thesis offers a rich new theory of touch through which to examine not only medieval plays but also other contemporary texts. Secondly, it challenges the prevailing view that medieval theatre appealed to the senses primarily or even exclusively via sight and hearing. Thirdly, it draws attention to an important sensory rupture in sixteenth-century England, one whose influence can be felt on the stage and beyond.

Age, depositional history and tectonics of the Indo-Burman ranges

This thesis examines the provenance and depositional processes of the sedimentary rocks of the Indo-Burman Ranges (IBR), discusses the tectonic evolution of the IBR, and provides a synthesis of the geological evolution of Myanmar. The IBR form an enigmatic mountain belt, comprising a western belt of folded and thrusted mainly Cenozoic sedimentary rocks, a central zone of highly deformed Triassic turbidites (Pane Chaung Formation) and low-grade metamorphic rocks (Kanpetlet Schist), and an eastern zone comprising a major Neo-Tethyan suture zone. The newly discovered early Jurassic-early Cretaceous radiolarian assemblages from ophiolitic mélange in the Kalemyo area and late Paleocene-early Eocene radiolarian ages from the Ngapali mélange, with ages similar to those of the Indus – Yarlung Tsangpo suture zone of south Tibet and Nagaland, reinforces the hypothesis that the Kalemyo - Nagaland suture and Indus – Yarlung Tsangpo suture represent a single suture zone that separates the Indian plate to the west (IBR) and Asian plate to the east (Central Basin and Wuntho-Popa Arc). The data presented suggest that Triassic turbidites were originally deposited on the northeastern India (Gondwana) margin, not the Asian (Sibumasu) plate, and that a wide Neo-Tethyan ocean separated the IBR from the Wuntho-Popa Arc (WPA) and the Shan Plateau. The geochemistry of detrital zircons from Upper Cretaceous sedimentary rocks of the IBR to be derived predominantly from the core of the IBR where marks a broad suture zone. Similar data from the Paleocene-Eocene flysch sediments suggest derivation from the Wuntho-Popa Arc and the core of the IBR.
