    With the implementation of inclusive education having become increasingly valued over the years, the training of Teaching Assistants (TAs) is now more important than ever, given that they work alongside pupils with special educational needs and disabilities (hereinafter SEND) in mainstream education classrooms. The current study explored the training factors that influence the role of TAs when it comes to teaching SEND students in mainstream classrooms in England during their one-year training period. This work aimed to increase understanding of how the training of TAs is seen to influence the development of their personal knowledge and professional skills. The study has significance for our comprehension of the connection between the TAs’ training and the quality of education in the classroom. In addition, this work investigated whether there existed a correlation between the teaching experience of TAs and their background information, such as their gender, age, grade level taught, years of teaching experience, and qualification level. A critical realist theoretical approach was adopted for this two-phased study, which involved the mixing of adaptive and grounded theories respectively. The multi-method project featured 13 case studies, each of which involved a trainee TA, his/her college tutor, and the classroom teacher who was supervising the trainee TA. The analysis was based on using semi-structured interviews, various questionnaires, and non-participant observation methods for each of these case studies during the TA’s one-year training period. The primary analysis of the research was completed by comparing the various kinds of data collected from the participants in the first and second data collection stages of each case. Further analysis involved cross-case analysis using a grounded theory approach, which made it possible to draw conclusions and put forth several core propositions. Compared with previous research, the findings of the current study reveal many implications for the training and deployment conditions of TAs, while they also challenge the prevailing approaches in many aspects, in addition to offering more diversified, enriched, and comprehensive explanations of the critical pedagogical issues

    How the Philosophy of Friedrich Nietzsche can be succinctly encapsulated within his Apollonian-Dionysian dichotomy

    Get PDF
    This thesis aims to illustrate that the broad philosophy of Friedrich Nietzsche can be subordinated to his conceptual dichotomy: the Apollonian-Dionysian dichotomy. Through an analysis of the Birth of Tragedy, Beyond Good and Evil, Twilight of the Idols, as well as a brief analysis of the Will to Power, I will make the case that the dichotomy is the umbrella under which all Nietzschean concepts are to be read and understood. The texts that were chosen represent key stages in Nietzsche’s intellectual development – from the Birth of Tragedy, which marks the beginning of Nietzschean philosophy; to Twilight of the Idols, which represents the end. The constituent parts of the dichotomy are to be understood in two contexts: firstly, the terms (Apollonian/Dionysian) are used to denote the forces required for the creation of art; secondly, the terms come to signify the type of individual who makes use of those forces as it is the case that different types of art can be created by different types of men. Nietzschean philosophy is to be understood through art as it is explicitly stated that the essence of existence is one of a perpetual Becoming wherein there exists only that which is created by man, for man, in service of man’s own will to power. All attempts to discern a fixed Being in-itself existing outside of this will to power are false and are indicative of a weak and sickly disposition, the symptoms of which are found in the progenitors’ art (be it a morality, table of categories, or a transcendent deity). Through the positing of the thing-in-itself as the will to power Nietzsche conceptualises the world of Becoming as a canvas onto which two different types of men imprint a Being which reveals, physiologically, their endowment as either Apollonian or Dionysian

    mSPD-NN: A Geometrically Aware Neural Framework for Biomarker Discovery from Functional Connectomics Manifolds

    Connectomics has emerged as a powerful tool in neuroimaging and has spurred recent advancements in statistical and machine learning methods for connectivity data. Despite connectomes inhabiting a matrix manifold, most analytical frameworks ignore the underlying data geometry. This is largely because simple operations, such as mean estimation, do not have easily computable closed-form solutions. We propose a geometrically aware neural framework for connectomes, i.e., the mSPD-NN, designed to estimate the geodesic mean of a collections of symmetric positive definite (SPD) matrices. The mSPD-NN is comprised of bilinear fully connected layers with tied weights and utilizes a novel loss function to optimize the matrix-normal equation arising from Fr\'echet mean estimation. Via experiments on synthetic data, we demonstrate the efficacy of our mSPD-NN against common alternatives for SPD mean estimation, providing competitive performance in terms of scalability and robustness to noise. We illustrate the real-world flexibility of the mSPD-NN in multiple experiments on rs-fMRI data and demonstrate that it uncovers stable biomarkers associated with subtle network differences among patients with ADHD-ASD comorbidities and healthy controls.Comment: Accepted into IPMI 202

    Boosting the Cycle Counting Power of Graph Neural Networks with I2^2-GNNs

    Full text link
    Message Passing Neural Networks (MPNNs) are a widely used class of Graph Neural Networks (GNNs). The limited representational power of MPNNs inspires the study of provably powerful GNN architectures. However, knowing one model is more powerful than another gives little insight about what functions they can or cannot express. It is still unclear whether these models are able to approximate specific functions such as counting certain graph substructures, which is essential for applications in biology, chemistry and social network analysis. Motivated by this, we propose to study the counting power of Subgraph MPNNs, a recent and popular class of powerful GNN models that extract rooted subgraphs for each node, assign the root node a unique identifier and encode the root node's representation within its rooted subgraph. Specifically, we prove that Subgraph MPNNs fail to count more-than-4-cycles at node level, implying that node representations cannot correctly encode the surrounding substructures like ring systems with more than four atoms. To overcome this limitation, we propose I2^2-GNNs to extend Subgraph MPNNs by assigning different identifiers for the root node and its neighbors in each subgraph. I2^2-GNNs' discriminative power is shown to be strictly stronger than Subgraph MPNNs and partially stronger than the 3-WL test. More importantly, I2^2-GNNs are proven capable of counting all 3, 4, 5 and 6-cycles, covering common substructures like benzene rings in organic chemistry, while still keeping linear complexity. To the best of our knowledge, it is the first linear-time GNN model that can count 6-cycles with theoretical guarantees. We validate its counting power in cycle counting tasks and demonstrate its competitive performance in molecular prediction benchmarks

    Identifying and responding to people with mild learning disabilities in the probation service

    It has long been recognised that, like many other individuals, people with learningdisabilities find their way into the criminal justice system. This fact is not disputed. Whathas been disputed, however, is the extent to which those with learning disabilities arerepresented within the various agencies of the criminal justice system and the ways inwhich the criminal justice system (and society) should address this. Recently, social andlegislative confusion over the best way to deal with offenders with learning disabilities andmental health problems has meant that the waters have become even more muddied.Despite current government uncertainty concerning the best way to support offenders withlearning disabilities, the probation service is likely to continue to play a key role in thesupervision of such offenders. The three studies contained herein aim to clarify the extentto which those with learning disabilities are represented in the probation service, toexamine the effectiveness of probation for them and to explore some of the ways in whichprobation could be adapted to fit their needs.Study 1 and study 2 showed that around 10% of offenders on probation in Kent appearedto have an IQ below 75, putting them in the bottom 5% of the general population. Study 3was designed to assess some of the support needs of those with learning disabilities in theprobation service, finding that many of the materials used by the probation service arelikely to be too complex for those with learning disabilities to use effectively. To addressthis, a model for service provision is tentatively suggested. This is based on the findings ofthe three studies and a pragmatic assessment of what the probation service is likely to becapable of achieving in the near future

    Consent and the Construction of the Volunteer: Institutional Settings of Experimental Research on Human Beings in Britain during the Cold War

    Get PDF
    This study challenges the primacy of consent in the history of human experimentation and argues that privileging the cultural frameworks adds nuance to our understanding of the construction of the volunteer in the period 1945 to 1970. Historians and bio-ethicists have argued that medical ethics codes have marked out the parameters of using people as subjects in medical scientific research and that the consent of the subjects was fundamental to their status as volunteers. However, the temporality of the creation of medical ethics codes means that they need to be understood within their historical context. That medical ethics codes arose from a specific historical context rather than a concerted and conscious determination to safeguard the well-being of subjects needs to be acknowledged. The British context of human experimentation is under-researched and there has been even less focus on the cultural frameworks within which experiments took place. This study demonstrates, through a close analysis of the Medical Research Council's Common Cold Research Unit (CCRU) and the government's military research facility, the Chemical Defence Experimental Establishment, Porton Down (Porton), that the `volunteer' in human experiments was a subjective entity whose identity was specific to the institution which recruited and made use of the subject. By examining representations of volunteers in the British press, the rhetoric of the government's collectivist agenda becomes evident and this fed into the institutional construction of the volunteer at the CCRU. In contrast, discussions between Porton scientists, staff members, and government officials demonstrate that the use of military personnel in secret chemical warfare experiments was far more complex. Conflicting interests of the military, the government and the scientific imperative affected how the military volunteer was perceived

    Statistical-dynamical analyses and modelling of multi-scale ocean variability

    This thesis aims to provide a comprehensive analysis of multi-scale oceanic variabilities using various statistical and dynamical tools and explore the data-driven methods for correct statistical emulation of the oceans. We considered the classical, wind-driven, double-gyre ocean circulation model in quasi-geostrophic approximation and obtained its eddy-resolving solutions in terms of potential vorticity anomaly and geostrophic streamfunctions. The reference solutions possess two asymmetric gyres of opposite circulations and a strong meandering eastward jet separating them with rich eddy activities around it, such as the Gulf Stream in the North Atlantic and Kuroshio in the North Pacific. This thesis is divided into two parts. The first part discusses a novel scale-separation method based on the local spatial correlations, called correlation-based decomposition (CBD), and provides a comprehensive analysis of mesoscale eddy forcing. In particular, we analyse the instantaneous and time-lagged interactions between the diagnosed eddy forcing and the evolving large-scale PVA using the novel `product integral' characteristics. The product integral time series uncover robust causality between two drastically different yet interacting flow quantities, termed `eddy backscatter'. We also show data-driven augmentation of non-eddy-resolving ocean models by feeding them the eddy fields to restore the missing eddy-driven features, such as the merging western boundary currents, their eastward extension and low-frequency variabilities of gyres. In the second part, we present a systematic inter-comparison of Linear Regression (LR), stochastic and deep-learning methods to build low-cost reduced-order statistical emulators of the oceans. We obtain the forecasts on seasonal and centennial timescales and assess them for their skill, cost and complexity. We found that the multi-level linear stochastic model performs the best, followed by the ``hybrid stochastically-augmented deep learning models''. The superiority of these methods underscores the importance of incorporating core dynamics, memory effects and model errors for robust emulation of multi-scale dynamical systems, such as the oceans.Open Acces

    Building body identities - exploring the world of female bodybuilders

    Get PDF
    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

    ‘Mental fight’ and ‘seeing & writing’ in Virginia Woolf and William Blake

    Get PDF
    This thesis is the first full-length study to assess the writer and publisher Virginia Woolf’s (1882-1941) responses to the radical Romantic poet-painter, and engraver, William Blake (1757-1827). I trace Woolf’s public and private, overt and subtle references to Blake in fiction, essays, notebooks, diaries, letters and drawings. I have examined volumes in Leonard and Virginia Woolf’s library that are pertinent, directly and indirectly, to Woolf’s understanding of Blake. I focus on Woolf’s key phrases about Blake: ‘Mental fight’, and ‘seeing & writing.’ I consider the other phrases Woolf uses to think about Blake in the context of these two categories. Woolf and Blake are both interested in combining visual and verbal aesthetics (‘seeing & writing’). They are both critical of their respective cultures (‘Mental fight’). Woolf mentions ‘seeing & writing’ in connection to Blake in a 1940 notebook. She engages with Blake’s ‘Mental fight’ in ‘Thoughts on Peace in an Air Raid’ (1940). I map late nineteenth and early twentieth-century opinion on Blake and explore Woolf’s engagement with Blake in these wider contexts. I make use of the circumstantial detail of Woolf’s friendship with the great Blake collector and scholar, Geoffrey Keynes (1887-1982), brother of Bloomsbury economist John Maynard Keynes. Woolf was party to the Blake centenary celebrations courtesy of Geoffrey Keynes’s organisation of the centenary exhibition in London in 1927. Chapter One introduces Woolf’s explicit references to Blake and examines the record of Woolf scholarship that unites Woolf and Blake. To see how her predecessors had responded, Chapter Two examines the nineteenth-century interest in Blake and Woolf’s engagement with key nineteenth-century Blakeans. Chapter Three looks at the modernist, early twentieth-century engagement with Blake, to contextualise Woolf’s position on Blake. Chapter Four assesses how Woolf and Blake use ‘Mental fight’ to oppose warmongering and fascist politics. Chapter Five is about what Woolf and Blake write and think about the country and the city. Chapter Six discusses Woolf’s reading of John Milton (1608-1674) in relation to her interest in Blake, drawing on the evidence of Blake’s intense reading of Milton. Chapter Seven examines further miscellaneous continuities between Woolf and Blake. Chapter Eight proposes, in conclusion, that we can only form an impression of Woolf’s Blake. The thesis also has three appendices. First, a chronology of key publications which chart Blake’s reputation as well as Woolf’s allusions to Blake. Second a list all of Blake’s poetry represented in Woolf’s library including contents page. The third lists all the other volumes in Woolf’s library that proved relevant. Although Woolf’s writing is the subject of this thesis, my project necessitates an attempt to recover how Blake was understood and misunderstood by numerous writers in the early twentieth century. The thesis argues Blake is a model radical Romantic who combines the visual and the verbal and that Woolf sees him as a kindred artist
