Thai is an alphasyllabic orthography and a tonal language with a non-linear arrangement of written vowels. The current study aimed to explore children’s Thai writing development through an error analysis of existing writing samples. An additional aim investigated the associations between the children’s Home Language and Literacy Environment (HLLE) and errors from the writing samples. The sample consisted of 31 Thai- English bilingual and multilingual children between 8-11 years of age from international schools across Thailand. The children’s writing samples were examined on factors that make up the translation processes of writing (transcription and text generation) including measures of word count, number of ideas and spelling errors. A spelling coding scheme was created to capture the different error types. Thai is a scriptio continua, which means that it has no spaces between words, so space knowledge is also important in Thai knowledge development.
All writing samples were examined for word count and spelling errors and a subset of the writing samples were analysed for idea units and space knowledge. Results showed a significant difference between more-skilled and less-skilled spellers for both word count and spelling errors. On average, more-skilled spellers wrote twice as many words than the lessskilled spellers and less-skilled spellers made more errors on all segments in a word (consonants, vowels, tones) compared to more-skilled spellers. In line with previous literature on Thai spelling development, more spelling errors were made for consonants followed by vowel and tone errors. Results indicate a positive relationship between idea production and word count, suggesting that children who have higher orthographic knowledge can divert their resources to the text-generation processes of writing. Further inspection is needed to understand the writing processes of a scriptio continua language.
As for the association between the HLLE and the child’s writing samples, correlation analysis showed a significant moderate correlation between the child activities in Thai and average word count, suggesting that the child independent activities in the home are associated with the productivity of writing. Results from the parents’ report on their child’s knowledge of Thai aksharas suggested that children have more difficulty writing, recognizing and spelling low-frequency aksharas than high-frequency aksharas. Finally, the current research highlights the insights of the home environment in association with Thai writing development but acknowledges the limitations and the need for future research.
Nuptial journeys: A cultural history of wedding travel in selected Habsburg unions ca 1450–1550

Keywords: early modern
medieval
Habsburg
nuptial journeys
memory
marriage rites
princely weddings
festival

Using the case study of Habsburg trans-European wedding alliances between 1450 to 1550, and drawing upon a significant reservoir of sources, this thesis shows that transfers of princely brides(grooms) were not an inconsequential side effect of weddings but were an ideal channel through which to negotiate the social status of dynasties, serve monarchical splendour and memory, prepare elite individuals for their new role and integrate them into their new environment, interact with foreign individuals and form relationships with them. Chapter One looks into logistical aspects and finds that planning and execution expressed the dynastic-political expectations of splendour and social standing of both wedding parties. Chapter Two examines the massive group of people accompanying the prince(ss), that was to serve her/his everyday needs but also to ameliorate the prince(ss)’s transition and project her/his and the dynasty’s social standing. Chapter Three addresses the staging of ceremonies, growing over time, which was an occasion to prolong the wedding festivities and to connect with the sacred sphere. Chapter Four looks into the marital transition and dissects the acts of separation and incorporation. Their phased progress and volatility points to the fact that the journey exceeds the anthropological concept of rites of passage. Drawing upon the empowering effect of liminality, Chapters Five and Six argue that the princesses engaged in preparation for their future role, participated in decision-making on the way, and used the journey to build relationships via gift-giving. Chapter Seven deals with the afterlife of the transfer in panegyric literary compositions and, by pinpointing the recurrent motifs of triumphalism and travel danger, it asserts that the voyages were an ideal instrument for dynastic memorialisation and propaganda. In general, this thesis questions the scholarly categories of ritual, festival, and ceremony, since these fall short of precisely defining the complex phenomenon of bridal journeys.
A critical study of the poetry of Al-Farazdaq
Keywords: poetry
Hammām ibn Ghālib
Al-Farazdaq

Hammām ibn Ghālib, known as al-Farazdag, was born in Kāẓimah, a seaside village near Baṣrah about the year 20 A.H. (642 A.D.). He belonged to the Banū Mujāshi' section of the Tamīm tribe, and his family included a number of men who were famous in pre-Islamic life. The poet's father, Ghālib, was famous for his generosity; he was specially remembered for two feats of mass slaughter of camels. His grandfather, Ṣa'ṣa'ah, was known as 'life-giver to infanticides' for his work in ransoming many victims of this practice. Al-Farazdaq was proud of his ancestors of whose glories he frequently boasted; but neither their noble birth nor their deeds were sufficiently exalted to justify the poet's boastful challenge to Mu'āwiyah:

Withdrawing from international regimes: bargaining power in the investment treaty regime
Keywords: international regimes
bilateral investment treaties
bargaining power
international cooperation

Why do some states withdraw from international regimes? How do others successfully renegotiate the terms of international cooperation? This thesis investigates whether, and how, the changing bargaining power relations impact treaty-based cooperation in the international investment treaty regime. The institutional architecture to govern investments consists of a web of bilateral investment treaties (BITs). The investor-state dispute settlement (ISDS) mechanism embedded in most BITs has resulted in an accumulation of arbitration cases between host governments and foreign investors, and states have increasingly begun to question their investment treaties.
I argue that while states have learned about the true risks of investment treaties through ISDS, they must have sufficient bargaining power to act in response. Bargaining power is best understood as alternatives to the existing agreements. Alternative economic treaties and domestic investment laws facilitate foreign investment and decrease dependency on the existing agreements. Economic improvement can also bring confidence for a government that such alternatives can be developed. When sufficient alternatives are in place, a state can either exit the agreement, demand renegotiation, or conduct a strategic exit with intentions to renegotiate at a later stage. The optimal strategy for a revisionist state depends on the bilateral relationship between the states, and how important they consider their partnership.
I employ a mixed methods approach to provide evidence for my argument. I use data on bilateral investment treaties to show that bargaining power is associated with greater risk of BIT termination and renegotiation. Relative changes in economic power also condition the effects of ISDS on BIT outcomes. Interviews conducted with Ecuadorian and Indonesian policymakers show that governments are strategic in reflecting on their outside options when considering BIT reform. By examining the dynamics of investment treaty reform, this thesis contributes to a better understanding of change in international regimes governing the world economy.
Leveraging genomic annotations to uncover latent components in gene expression data
Keywords: statistical learning

Over the last decade single cell genomics has transformed research in genetics, resolving transcriptional activity at an unprecedented resolution. Over 1000 single cell studies have been published to date and the scale of single cell data is increasing, cell atlases of complex organisms are being curated, and experimental sample sizes are increasing exponentially.
Standard analyses for single cell data include a hard clustering of cells and an investigation of these clusters to identify cell-specific marker genes. This approach is powerful and identifies transcriptomic differences between cells. However, such analyses fail to account for biological heterogeneity present in continuous developmental processes taking place in cells, or to use relevant prior information that may be available to the researcher. In this thesis we investigate incorporating prior information into factor analysis for gene expression analyses, which infers components of genes that are coexpressed or co-repressed across cells, and their expression in each cell. First, we consider structural features of the data, extending an existing tensor decomposition method to four dimensions, facilitating analysis of gene expression data indexed by cell, time, tissue and gene. We demonstrate the relative benefits of the method against a lower dimensional method. Secondly, we develop a widely applicable new prior structure and inference algorithm that allows for incorporating external prior information into factor analysis. The new algorithm automatically selects important annotations and leverages this information to infer biologically meaningful components. Comparing two likelihood models, we evaluate their strengths and weaknesses on simulated data, and the benefit of incorporating prior information into the algorithm. We demonstrate the power of the method to capture meaningful components of expression on a well-studied single cell RNA-seq dataset from cells undergoing spermatogenesis, using transcription factor binding affinities as prior information, and demonstrate the utility of the new prior structure in leveraging such annotations.
Too weak for biophysics: Prioritising and progressing fragment hits from X-ray crystallographic screening.
Keywords: crystallographic soaking

fragment-based drug dicovery
crystallographic fragment screening
fragment elaboration

In the last decade, X-ray crystallography has matured to a powerful primary screening technique for fragment hit identification in structure-based drug discovery. Unmatched in its sensitivity, it provides valuable knowledge of precise fragment binding location in a protein-fragment complex. The comparison to 19F NMR fragment campaign conducted in this work emphasises the strength of crystallographic screening by revealing additional binding sites and interactions for the breast cancer target NUDT5.
The high sensitivity of X-ray crystallography allows to identify even weakly binding fragment hits, which are often undetectable by commonly used biophysical methods. The lack of orthogonal tools with sufficient detection limits to quantify their interactions impedes prioritisation of fragment hits for elaboration. For this purpose, the use of both NMR-based techniques as well as concentration-dependent crystallographic soaking are explored. While further investigation of relaxation-based T1rho NMR for rapid ranking of weak binders is necessary, the crystallographic approach demonstrates a correlation between the lowest detectable soaking concentration (LDSC) and fragment binding affinity. A low-concentration counter-soak is proposed as a simple solution to triage fragment hits according to their binding strengths, streamlining their selection for further elaboration.
Weak fragment hits can be informative for lead discovery: they can reveal unknown binding sites and can be progressed into more potent compounds. For the target NUDT5, crystallographic screening identified a novel, previously unreported binding pocket. The elaboration efforts utilising SAR by catalogue approach and crystallographic soaking as readout highlight the value of crystallography for the progression of weak binders in absence of other assays.
Curing through questioning? A cross-cultural analysis of Pyrrhonism, Madhyamaka, and their potential as philosophical therapy
Keywords: Philosophy as therapy
Madhyamaka
Pyrrhonism
Scepticism

This thesis shows what we may learn about ancient Pyrrhonian scepticism, Indian Madhyamaka Buddhism, and their potential as philosophical therapy, by examining the two traditions in conjunction. It aims to accomplish three goals: present a robust comparison of Pyrrhonism and Madhyamaka; demonstrate that significant insights may be gained from this juxtaposition; and show that these two traditions challenge current ways of doing philosophy.
The thesis starts by examining the preconditions of fruitful cross-cultural research; it is shown that ascribing too much or too little importance to context (radical relativism and universalism, respectively) is problematic. Previous comparisons of Pyrrhonism and Madhyamaka have paid little attention to such methodological considerations, which has led to crucial shortcomings. This is unfortunate, because their remarkable parallels demand a representative, accessible overview. Having laid the necessary foundations, the thesis presents such an overview. A therapeutic framework is employed to systematically compare the two traditions, including their diagnoses of disturbance, their proposed cures, and their promised cured conditions. Such themes allow for systematically outlining their similarities and differences and to limit arbitrariness and bias.
Despite their striking similarities, very few attempts have been made to learn about Pyrrhonism and Madhyamaka by studying them in conjunction. This thesis corrects this oversight by demonstrating that such cross-cultural research enables us to shed new light on persistent ambiguities and allows us to bolster and defend both traditions. For example, it is demonstrated that Madhyamaka can shine a new light on one of the, if not the most vexed question regarding Pyrrhonism: what is the scope of suspension of judgment?
Finally, this thesis shows that Pyrrhonism and Madhyamaka challenge the practice of philosophy itself. It is demonstrated that contemporary schools of thought akin to Pyrrhonism and Madhyamaka may share their therapeutic potential. If so, then certain contemporary philosophies are able to alleviate distress and instil a sense of tranquillity. This means we must expand our understanding of what philosophy can do. After all, if contemporary philosophy can change our experience of the world for the better, it has a much greater potential than is currently believed—both in terms of audience and impact.
Unveiling the protein-protein interactome of the RNA-binding
protein Rev in HIV-1 infected T CD4+ lymphocytic cells
Keywords: HIV-1

Human immunodeficiency virus type I (HIV-1) is a retrovirus that causes acquired immunodeficiency syndrome (AIDS) and affects ~38 million people worldwide. The HIV-1 protein Rev escorts under-spliced viral RNAs to the cytoplasm, overriding nuclear retention imposed by the host cell. Thus, Rev permits full viral gene expression and particle production. However, Rev is challenging to study as it is highly disordered, expressed at low levels and encoded by an open reading frame that overlaps other viral genes. Therefore, previous Rev research was largely performed under non-physiological conditions, leaving the physiological interactions and functions of Rev uncertain. Here, I engineered HIV-1 constructs that encode tagged Rev protein expressed to physiological levels. I used these constructs to immunoprecipitate Rev interactors in CD4+ cells, revealing the physiological interactome of Rev. Through meta-analysis of this novel interactome and previously published datasets, I provide evidence for a new connection between Rev-mediated export and HIV-1 virion assembly. Furthermore, I investigate the interactions of two packaged proteins, PURA and PURB, during HIV-1 replication, to reveal possible therapeutic targets. My research uncovers the localisation, interactions and functions of Rev during HIV-1 replication under conditions better approximating physiological conditions than previously used. This work thus provides highly valuable datasets to instruct new avenues of research on the HIV-1 infection cycle.

Approximately 80% of the Chinese modern vocabulary are compound words. Because of this characteristic, Chinese lexical morphology also focuses highly on compound words. The study’s purpose was to investigate a Mandarin Chinese vocabulary intervention that trained lexical compounding awareness in third-graders to explore if targeted lexical compounding awareness training can improve vocabulary depth. The study was conducted in a low-income community in rural China where academic achievement falls below the national average. The study hopes to provide insight into the feasibility of vocabulary interventions in diverse settings in China. Participants were 57 third-grade students from rural China. A mixed-methods design was adopted to address research questions: a within-subject quasi-experimental design aimed to evaluate the effectiveness of the intervention of morphological awareness and vocabulary depth, and a thematic analysis of teacher interviews explored teachers’ experiences of the intervention. The research questions looked at: 1. Does an intervention that focuses on systematically instructing on Chinese compound lexical structures affect third graders’ Chinese vocabulary knowledge? Specifically, a) Does targeted training in Chinese compound lexical structures increase children’s compound lexical awareness and vocabulary depth? b) Does the vocabulary knowledge of taught words from targeted training in compound lexical structures transfer towards novel words? c) Is there a relationship between initial skills in vocabulary depth and morphological compound awareness and their improvement post-intervention? 2. What are teachers’ perspectives and experiences of the Lexical Compounding Awareness? A paired samples t-test showed that there was an improvement between pre and post-test assessment performance. ANOVA showed a strong transfer effect from morphological awareness and vocabulary knowledge of taught words to other novel words. Significant strong correlations also showed that initially low-performing students showed the greater improvement after intervention. The teachers who delivered the intervention also expressed an overall positive experience of the intervention. Implications for future research and practice in literacy interventions and morphological training for vocabulary growth are discussed.
The epidemiology of hand osteoarthritis
Keywords: hand osteoarthritis
epidemiology

Background
Radiographic osteoarthritis most commonly affects joints in the hands, with osteoarthritis at the finger interphalangeal joints (IPJs) thought to be a different subset to that at the first carpometacarpal joint (CMCJ). The thesis aimed to identify risk factors for hand (particularly IPJ) osteoarthritis.
Methods
Systematic reviews and Delphi studies were performed to identify risk and prognostic factors for incident and progressive IPJ osteoarthritis. A risk prediction model for incident radiographic IPJ osteoarthritis (Kellgren Lawrence (KL) ≥2 in ≥1 IPJ), and a prognostic model for the progression of IPJ osteoarthritis (increase of KL ≥1 in ≥1 IPJ), in the Chingford 1000 Women Study were developed. As the prognostic model performance was poor, the model was revised in the Johnston County Osteoarthritis (JoCo) Project. The burden of hand injury requiring hospital admission, and the association between hand injury and osteoarthritis was investigated in cricketers.
Results
From the systematic review and Delphi study for incident IPJ osteoarthritis, older age in women, female sex, family history, and injury were important risk factors. Whilst for the progression of IPJ osteoarthritis, older age and family history were important prognostic factors. The prediction model included 459 participants (257 with osteoarthritis at 10 years). Older age, manual occupation, and first CMCJ osteoarthritis were important predictors. The prognostic model included 195 participants (181 progressing at 10 years), with no prognostic factors found to be important. Following revision, female sex was found to be an important factor. Over ten years, 9,188 cricketers presented with hand injuries, most commonly in young adults, with thumb and little finger injuries, particularly fractures and dislocations. Hand injury was associated with osteoarthritis.
Conclusion
IPJ osteoarthritis might be a continuum of first CMCJ osteoarthritis. Manual occupation and injury could be targeted to decrease disease risk, whilst older age is an unmodifiable risk factor.
