    Many theoretical extensions of the Standard Model predict the existence of new long-lived particles that are within the discovery reach of the Large Hadron Collider (LHC). This thesis presents a search for long-lived particles that decay to a pair of tau leptons, one then decaying hadronically and the other leptonically. Tau final states are on the interface between leptonic and hadronic searches and are much less thoroughly constrained. Several approaches are taken to address some of the experimental challenges encountered in the search for displaced hadronic taus. The development of a novel tau track classification algorithm capable of accurately identifying tracks belonging to taus decaying to one or three charged pions is detailed. The resulting displaced track classifier demonstrates significantly higher efficiency compared to the nominal recommendations. Enhancements made to the existing ATLAS track classification algorithm in preparation for Run 3 data taking at the LHC are also outlined. A newly developed RNN-based algorithm for identifying displaced tau leptons is presented in this thesis. When combined with the displaced track classification algorithm, this results in a displaced tau identification procedure that significantly improves background rejection and signal acceptance for displaced taus in a model-independent way. With efficiency gains of classifying 1-prong taus from about 40% to 80% and 3-prong taus from about 20% to 60%. The thesis primarily presents a methodology combining reconstruction and identification techniques which are then folded into an analysis targeting exotic long-lived particles decaying to tau leptons. This signature-driven analysis targets the first stringent limits on long-lived particles decaying to third generation leptons. Major steps in this analysis have been taken and results presented

    This thesis examined relationships between psychological flexibility, psychological inflexibility, prejudicial attitudes, and dehumanization across three cross-sectional studies with an additional proposed experimental study. Psychological flexibility refers to mindful attention to the present moment, willing acceptance of private experiences, and engaging in behaviours congruent with one’s freely chosen values. Inflexibility, on the other hand, indicates a tendency to suppress unwanted thoughts and emotions, entanglement with one’s thoughts, and rigid behavioural patterns. Study 1 found limited correlations between inflexibility and sexism, racism, homonegativity, and dehumanization. Study 2 demonstrated more consistent positive associations between inflexibility and prejudice. And Study 3 controlled for right-wing authoritarianism and social dominance orientation, finding inflexibility predicted hostile sexism and racism beyond these factors. While showing some relationships, particularly with sexism and racism, psychological inflexibility did not consistently correlate with varied prejudices across studies. The proposed randomized controlled trial aims to evaluate an Acceptance and Commitment Therapy intervention to reduce sexism through enhanced psychological flexibility. Overall, findings provide mixed support for the utility of flexibility-based skills in addressing complex societal prejudices. Research should continue examining flexibility integrated with socio-cultural approaches to promote equity

    Separately, Connectedly: Exploring Trauma Through Ekphrasis in Contemporary Novels

    Get PDF
    This thesis examines ekphrasis as a rhetorical tool to explore, represent, and contemplate trauma affect in contemporary novels. From the Greek phrase for ‘description,’ ekphrasis is part of a long and ancient literary tradition, dating as far back as the ancient depictions of art on urns, weaponry, as well as more disambiguated descriptions of scenes and people. The uses of ekphrasis as a literary device are broad and complex, but its use is under-researched in contemporary novels, and there is a near total absence of investigation into ekphrasis within the novel as a means of contemplating and understanding the affect of a condition that is inherently abstract and disorienting.Literary trauma theory has evolved considerably in recent years. In keeping with important findings in psychology and psychiatric research, there is a broad recognition that rethinking trauma representation beyond the recitation and reliving of events and into textured descriptions of trauma affect is essential for thoughtful, nuanced explorations of an experience that resists narrative convenience. As a result, there are increased calls to accept and represent its inherent fractured nature and resist the authorial temptation to forge a story around it that fits neatly into a cohesive whole. This thesis proposes a framework for considering how various aspects of ekphrastic descriptions of real and imagined art as well as their connotative and denotative significance in the novel reveals nuance in the representation of trauma affect through the activation of language and image. The contemporary novels explored herein are: The Goldfinch by Donna Tartt, What I Loved by Siri Hustvedt, and How to Be Both by Ali Smith. Each of these novels present ekphrasis and affect differently, which enables broader testing of the flexibility of the proposed framework

    Neuroimaging investigations of cortical specialisation for different types of semantic knowledge

    Get PDF
    Embodied theories proposed that semantic knowledge is grounded in motor and perceptual experiences. This leads to two questions: (1) whether the neural underpinnings of perception are also necessary for semantic cognition; (2) how do biases towards different sensorimotor experiences cause brain regions to specialise for particular types of semantic information. This thesis tackles these questions in a series of neuroimaging and behavioural investigations. Regarding question 1, strong embodiment theory holds that semantic representation is reenactment of corresponding experiences, and brain regions for perception are necessary for comprehending modality-specific concepts. However, the weak embodiment view argues that reenactment may not be necessary, and areas near to perceiving regions may be sufficient to support semantic representation. In the particular case of motion concepts, lateral occipital temporal cortex (LOTC) has been long identified as an important area, but the roles of its different subregions are still uncertain. Chapter 3 examined how different parts of LOTC reacted to written descriptions of motion and static events, using multiple analysis methods. A series of anterior to posterior sub-regions were analyzed through univariate, multivariate pattern analysis (MVPA), and psychophysical interaction (PPI) analyses. MVPA revealed strongest decoding effects for motion vs. static events in the posterior parts of LOTC, including both visual motion area (V5) and posterior middle temporal gyrus (pMTG). In contrast, only the middle portion of LOTC showed increased activation for motion sentences in univariate analyses. PPI analyses showed increased functional connectivity between posterior LOTC and the multiple demand network for motion events. These findings suggest that posterior LOTC, which overlapped with the motion perception V5 region, is selectively involved in comprehending motion events, while the anterior part of LOTC contributes to general semantic processing. Regarding question 2, the hub-and-spoke theory suggests that anterior temporal lobe (ATL) acts as a hub, using inputs from modality-specific regions to construct multimodal concepts. However, some researchers propose temporal parietal cortex (TPC) as an additional hub, specialised in processing and integrating interaction and contextual information (e.g., for actions and locations). These hypotheses are summarized as the "dual-hub theory" and different aspects of this theory were investigated in in Chapters 4 and 5. Chapter 4 focuses on taxonomic and thematic relations. Taxonomic relations (or categorical relations) occur when two concepts belong to the same category (e.g., ‘dog’ and ‘wolf’ are both canines). In contrast, thematic relations (or associative relations) refer to situations that two concepts co-occur in events or scenes (e.g., ‘dog’ and ‘bone’), focusing on the interaction or association between concepts. Some studies have indicated ATL specialization for taxonomic relations and TPC specialization for thematic relations, but others have reported inconsistent or even converse results. Thus Chapter 4 first conducted an activation likelihood estimation (ALE) meta-analysis of neuroimaging studies contrasting taxonomic and thematic relations. This found that thematic relations reliably engage action and location processing regions (left pMTG and SMG), while taxonomic relations only showed consistent effects in the right occipital lobe. A primed semantic judgement task was then used to test the dual-hub theory’s prediction that taxonomic relations are heavily reliant on colour and shape knowledge, while thematic relations rely on action and location knowledge. This behavioural experiment revealed that action or location priming facilitated thematic relation processing, but colour and shape did not lead to priming effects for taxonomic relations. This indicates that thematic relations rely more on action and location knowledge, which may explain why the preferentially engage TPC, whereas taxonomic relations are not specifically linked to shape and colour features. This may explain why they did not preferentially engage left ATL. Chapter 5 concentrates on event and object concepts. Previous studies suggest ATL specialization for coding similarity of objects’ semantics, and angular gyrus (AG) specialization for sentence and event structure representation. In addition, in neuroimaging studies, event semantics are usually investigated using complex temporally extended stimuli, unlike than the single-concept stimuli used to investigate object semantics. Thus chapter 5 used representational similarity analysis (RSA), univariate analysis, and PPI analysis to explore neural activation patterns for event and object concepts presented as static images. Bilateral AGs encoded semantic similarity for event concepts, with the left AG also coding object similarity. Bilateral ATLs encoded semantic similarity for object concepts but also for events. Left ATL exhibited stronger coding for events than objects. PPI analysis revealed stronger connections between left ATL and right pMTG, and between right AG and bilateral inferior temporal gyrus (ITG) and middle occipital gyrus, for event concepts compared to object concepts. Consistent with the meta-analysis in chapter 4, the results in chapter 5 support the idea of partial specialization in AG for event semantics but do not support ATL specialization for object semantics. In fact, both the meta-analysis and chapter 5 findings suggest greater ATL involvement in coding objects' associations compared to their similarity. To conclude, the thesis provides support for the idea that perceptual brain regions are engaged in conceptual processing, in the case of motion concepts. It also provides evidence for a specialised role for TPC regions in processing thematic relations (pMTG) and event concepts (AG). There was mixed evidence for specialisation within the ATLs and this remains an important target for future research

    A Critical Review Of Post-Secondary Education Writing During A 21st Century Education Revolution

    Educational materials are effective instruments which provide information and report new discoveries uncovered by researchers in specific areas of academia. Higher education, like other education institutions, rely on instructional materials to inform its practice of educating adult learners. In post-secondary education, developmental English programs are tasked with meeting the needs of dynamic populations, thus there is a continuous need for research in this area to support its changing landscape. However, the majority of scholarly thought in this area centers on K-12 reading and writing. This paucity presents a phenomenon to the post-secondary community. This research study uses a qualitative content analysis to examine peer-reviewed journals from 2003-2017, developmental online websites, and a government issued document directed toward reforming post-secondary developmental education programs. These highly relevant sources aid educators in discovering informational support to apply best practices for student success. Developmental education serves the purpose of addressing literacy gaps for students transitioning to college-level work. The findings here illuminate the dearth of material offered to developmental educators. This study suggests the field of literacy research is fragmented and highlights an apparent blind spot in scholarly literature with regard to English writing instruction. This poses a quandary for post-secondary literacy researchers in the 21st century and establishes the necessity for the literacy research community to commit future scholarship toward equipping college educators teaching writing instruction to underprepared adult learners

    Fictocritical Cyberfeminism: A Paralogical Model for Post-Internet Communication

    Get PDF
    This dissertation positions the understudied and experimental writing practice of fictocriticism as an analog for the convergent and indeterminate nature of “post-Internet” communication as well a cyberfeminist technology for interfering and in-tervening in metanarratives of technoscience and technocapitalism that structure contemporary media. Significant theoretical valences are established between twen-tieth century literary works of fictocriticism and the hybrid and ephemeral modes of writing endemic to emergent, twenty-first century forms of networked communica-tion such as social media. Through a critical theoretical understanding of paralogy, or that countercultural logic of deploying language outside legitimate discourses, in-volving various tactics of multivocity, mimesis and metagraphy, fictocriticism is ex-plored as a self-referencing linguistic machine which exists intentionally to occupy those liminal territories “somewhere in among/between criticism, autobiography and fiction” (Hunter qtd. in Kerr 1996). Additionally, as a writing practice that orig-inated in Canada and yet remains marginal to national and international literary scholarship, this dissertation elevates the origins and ongoing relevance of fictocriti-cism by mapping its shared aims and concerns onto proximal discourses of post-structuralism, cyberfeminism, network ecology, media art, the avant-garde, glitch feminism, and radical self-authorship in online environments. Theorized in such a matrix, I argue that fictocriticism represents a capacious framework for writing and reading media that embodies the self-reflexive politics of second-order cybernetic theory while disrupting the rhetoric of technoscientific and neoliberal economic forc-es with speech acts of calculated incoherence. Additionally, through the inclusion of my own fictocritical writing as works of research-creation that interpolate the more traditional chapters and subchapters, I theorize and demonstrate praxis of this dis-tinctively indeterminate form of criticism to empirically and meaningfully juxtapose different modes of knowing and speaking about entangled matters of language, bod-ies, and technologies. In its conclusion, this dissertation contends that the “creative paranoia” engendered by fictocritical cyberfeminism in both print and digital media environments offers a pathway towards a more paralogical media literacy that can transform the terms and expectations of our future media ecology

    Effects of trunk-focused exercise programs and how the training program and the individuals’

    Get PDF
    Trunk-focused exercise programs (TEP) refer to those training programs in which the main target of the exercises resides in the active and/or passive trunk/core structures. Although these programs have shown a positive impact in sport and health contexts throughout recent years, there are several limitations in the literature that hinder the understanding of TEP effect and their relationship to the individual and to the training load characteristics. In this sense, TEP are sometimes compared to exercise control groups and/or other exercise programs that include trunk-focused exercises. Furthermore, although the individual and the training program features are a basic aspect to optimize training programs, experimental TEP studies not always provide this information properly. To address these constraints, the present doctoral thesis includes two systematic reviews and an experimental study. The two systematic reviews aimed at an in-depth analysis of the literature on TEP both, to improve the knowledge about the trunk-focused exercise contribution to increase trunk physical fitness and ameliorate stroke and low back pain symptoms, and to better understand how the individuals and exercise programs characteristics modulate TEP effectiveness. Overall, although the quality of evidence was low, their results showed that TEP were effective to ameliorate stroke and patients’ non-specific chronic low back pain condition, with positive effects in all the outcomes analysed. Furthermore, the analysis of moderator factors revealed that TEP effectiveness in stroke patients seems to be higher when the initial trunk impairment is greater, the patients are older, and the intervention starts earlier. Importantly, the TEP impact on low back pain symptoms (mainly pain reduction) seems higher when a greater improvement in trunk and/or hip range of motion is recorded after the training program and participants have a lower body mass index. These results reinforce the importance of paying close attention to the individuals and to the exercise programs characteristics when designing this type of interventions. On the other hand, the experimental study overcomes some of the problems found in the systematic reviews, especially the lack of experimental works that objectively controlled the training load intensity. This study aimed at the comparison of the effects of a higher intensity and a higher volume core stability exercise (CSE) program on core stability, core endurance and whole-body dynamic balance in young physically active males, using a smartphone-accelerometer to control the CSE intensity. These study results showed the specificity of the effects caused by the CSE programs, with a larger increase in the lumbopelvic postural control during the execution of isometric CSE for the higher intensity CSE program and a larger core endurance increase for the higher volume CSE program. Interestingly, the performance of conventional isometric CSE in lying and quadruped positions during the CSE programs did not have a significant impact on the unstable sitting test, a sudden loading protocol and several whole-body dynamic balance tests. Altogether, the results of the studies included in this doctoral thesis highlight the importance of performing TEP to improve trunk performance, functional capacity,and health status in different populations. Specifically, the two systematic reviews showed how moderator factors related to both, the individual and the training program characteristics can play an important role in modulating TEP effectiveness, which should be considered to maximize and tailor the TEP benefits in stroke and low back pain patients. However, the quality of the evidence for all the outcomes analysed in these systematic reviews was low, and thus, higher quality studies are required to strengthen the evidence on the impact of performing trunk-focused exercises in stroke and low back pain rehabilitation programs. Regarding the experimental study, the training load control performed through the smartphone-accelerometer allowed to describe the specificity of the effects caused by a higher intensity and a higher volume CSE program in young physically active males. Further research is needed to characterize the dose-response relationship of CSE programs in different populations properly.Los programas de ejercicio focalizados en el tronco (PET) son aquellos programas de entrenamiento cuyo foco principal son las estructuras activas y/o pasivas del tronco/core. A pesar de que estos programas han mostrado un efecto positivo tanto en contextos deportivos como de salud a lo largo de los últimos años, se observan varias limitaciones en la literatura que dificultan entender adecuadamente el efecto que tienen estos programas y su relación tanto con las características de los participantes, como con las características de los programas de entrenamiento. En este sentido, los PET son comparados en ocasiones con grupos control y/u otros programas de entrenamiento que incluyen ejercicios focalizados en el tronco. Además, a pesar de que las características de los participantes y de los programas de entrenamiento son aspectos clave para su optimización, los estudios experimentales no siempre aportan esta información. Para abordar estas limitaciones, la presente tesis doctoral incluye dos revisiones sistemáticas y un estudio experimental. Las dos revisiones sistemáticas presentan un análisis detallado de la literatura relacionadas con los PET para, a) mejorar el conocimiento sobre la contribución de los ejercicios focalizados en el tronco sobre el desarrollo de la condición física del tronco y la mejora de los síntomas tanto en personas que han sufrido un ictus, como en pacientes con dolor lumbar, y b) comprender mejor cómo las características de los participantes y de los programas de entrenamiento modulan la efectividad de los PET. En general, a pesar de que la calidad de la evidencia fue baja, los resultados de estas revisiones mostraron la efectividad de los PET para mejorar la condición tanto de las personas que han sufrido un ictus, como de aquellas con dolor lumbar crónico inespecífico, obteniendo efectos positivos sobre todas las variables analizadas. Además, el análisis de los factores moderadores reveló que la efectividad de los PET en personas que han sufrido un ictus parece ser mayor cuando la afectación inicial del tronco es mayor, las personas son mayores o el programa de ejercicio comienza antes. Con respecto a las personas con dolor lumbar, el impacto de los PET sobre la reducción de los síntomas (especialmente la reducción del dolor), parece ser mayor cuando hay un mayor incremento del rango de movimiento del tronco y/o de la cadera y los participantes tienen un menor índice de masa corporal. Estos resultados refuerzan la importancia de prestar atención a las características de los participantes y de los programas de ejercicios cuando se diseñan este tipo de programas. Por otro lado, el estudio experimental que incluye esta tesis doctoral aborda algunos de los problemas observados en las revisiones sistemáticas, especialmente la falta de estudios experimentales que controlen de manera objetiva la carga de entrenamiento de los PET. En este sentido, este estudio tuvo como objetivo comparar los efectos de dos programas de ejercicios de estabilidad del tronco (EET), uno de mayor intensidad y otro de mayor volumen, sobre la estabilidad y resistencia del tronco y el equilibrio dinámico general en hombres jóvenes y físicamente activos, utilizando el acelerómetro integrado en un smartphone para controlar la intensidad de los EET. Los resultados mostraron la especificidad de los efectos de los programas de EET, con mayores mejoras sobre el control lumbo-pélvico durante la ejecución de EET isométricos en el grupo de mayor intensidad y un mayor efecto sobre la resistencia de los músculos tronco en el grupo de mayor volumen. Destacar también que la realización de EET isométricos en posiciones de tumbado y cuadrupedia no tuvo un impacto significativo sobre el test del asiento inestable, sobre un protocolo de perturbaciones súbitas y sobre varios test de equilibrio dinámico general. En resumen, los resultados de los estudios incluidos en esta Tesis Doctoral destacan la importancia de realizar PET para mejorar la condición física del tronco, la capacidad funcional y el estado de salud en diferentes poblaciones. Específicamente, las dos revisiones sistemáticas mostraron cómo factores moderadores relacionados con las características de los participantes y de los programas de entrenamiento pueden jugar un papel importante en la modulación de la efectividad de los PET, lo cual debería tenerse en cuenta para maximizar sus beneficios en personas que han sufrido un ictus y en pacientes con dolor lumbar. Sin embargo, la calidad de la evidencia de los estudios en los parámetros analizados fue baja y, por lo tanto, es necesario que estudios de mayor calidad refuercen y mejoren los resultados obtenidos sobre el impacto de los PET en estas poblaciones. Con respecto al estudio experimental, el control de la carga de entrenamiento a través del acelerómetro integrado en un smartphone permitió describir la especificidad de los efectos de un programa de EET de mayor intensidad y de otro de mayor volumen en hombres jóvenes y físicamente activos. Futuros estudios son necesarios para caracterizar de manera adecuada la relación dosis-respuesta de los programas de EET en diferentes poblaciones

    Out-of-Distribution Generalization of Deep Learning to Illuminate Dark Protein Functional Space

    Dark protein illumination is a fundamental challenge in drug discovery where majority human proteins are understudied, i.e. with only known protein sequence but no known small molecule binder. It\u27s a major road block to enable drug discovery paradigm shift from single-targeted which looks to identify a single target and design drug to regulate the single target to multi-targeted in a Systems Pharmacology perspective. Diseases such as Alzheimer\u27s and Opioid-Use-Disorder plaguing millions of patients call for effective multi-targeted approach involving dark proteins. Using limited protein data to predict dark protein property requires deep learning systems with OOD generalization capacity. Out-of-Distribution (OOD) generalization is a problem hindering the application and adoption of deep learning in real world problems. Classic deep learning setting in contrast is assuming training and testing data are independent identically distributed (iid). A well trained model under iid setting with reported 98% accuracy could deteriorate to worse than random guess in deployment to OOD data significantly different from training data. Numerous techniques in the research field emerged but are only addressing some specific OOD scenario instead of a general one. Dark protein illumination has unique complexity comparing to common deep learning tasks. There are three OOD axes, protein-OOD, compound-OOD, interaction-OOD. Previous research have only focused on compound-OOD, where new compound design algorithms are developed but still for 500 common proteins, instead of whole human genome 20,000 proteins, and only for single-targeted paradigm instead of multi-targeted. Focusing on an instrumental problem in drug discovery, dark protein function illumination problem is introduced from the OOD perspective. A series of dark protein OOD algorithms are developed to predict dark protein ligand interaction where multiple instrumental deep learning techniques are adapted to the biology context. By proposing the dark protein illumination problem, highlighting the neglected axes, demonstrating possibilities, numerous diseases now embrace new hopes

    Resumen de tesis. Development of ultra-stable characterization techniques for ultrashort laser beams

    [EN]The dramatic evolution that the laser Science has undergone in the last six decades, and particularly in the field of ultrashort pulses, has been accompanied by breakthrough advances in the development of techniques for their characterization. Despite the large number of characterization techniques developed in the last two decades, it is still necessary to Implement simpler and more robust techniques that can also operate in multiple spectral ranges. This Thesis is devoted to the study and development of temporal and spatiotemporal characterization techniques with compact and stable configurations, which are versatile, e.g., to analyze ultrashort laser beams with different temporal durations and in various spectral regions. The structure of this Thesis is made up of four main blocks. Firstly, a brief introduction to ultrafast optical metrology and the state of the art of spatial, temporal and spatiotemporal characterization techniques is presented in Part I. Then, Part II is focused on the review and extension of the capabilities of the amplitude swing temporal characterization technique, demonstrating three key advances: operation in different spectral regions from visible to near-infrared, with a tunability range spanning of more than one octave; Characterization of ultrashort pulses in the few-cycle regime; or study of the implementation with different amplitude modulation schemes. In addition, a new retrieval algorithm is developed to analyze the amplitude swing traces based on differential evolution strategies. Thirdly, the fundamentals, operation range and experimental demonstration of a spatiotemporal characterization technique based on bulk lateral shearing interferometry are depicted in Part III. Furthermore, the technique is applied to characterize complex spatiotemporal couplings, like constant and time-varying optical vortices or the aberrations when focusing with astigmatic lenses. Finally, the main conclusions of the work and future perspectives are discussed in Part IV[ES]La drástica evolución que ha experimentado la ciencia láser en las últimas seis décadas, y en particular en el campo de los pulsos ultracortos, ha ido acompañada de grandes avances en el desarrollo de técnicas para su caracterización.

Esta Tesis está dedicada al estudio y desarrollo de técnicas de caracterización temporal y espaciotemporal con configuraciones compactas y estables, que sean versátiles para, por ejemplo, analizar haces láser ultracortos con diferentes duraciones temporales y en diversas regiones espectrales. La estructura de la Tesis está dividida en cuatro bloques principales. En primer lugar, en la Parte I se presenta una breve introducción a la metrología óptica ultrarrápida y los avances de las técnicas de caracterización espacial, temporal y espaciotemporal a lo largo de los últimos años. Después, la Parte II se enfoca en la revisión y extensión de las capacidades de la técnica de caracterización temporal amplitude swing, demostrando tres avances clave: operación en diferentes regiones espectrales desde visible hasta infrarrojo cercano, con un rango de sintonizabilidad que abarca más de una octava; caracterización de pulsos ultracortos en régimen de pocos ciclos; o estudio de diferentes esquemas de modulación de amplitud. Además, se implementa un nuevo algoritmo de reconstrucción para analizar las trazas del sistema amplitude swing basado en las estrategias Differential Evolution. En tercer lugar, en la Parte III se describen los fundamentos, el rango de operación y la demostración experimental de una técnica de caracterización espaciotemporal basada en la interferometría lateral compacta (bulk lateral shearing interferometry). Además, la técnica se emplea para caracterizar acoplamientos espaciotemporales complejos, como son los vórtices ópticos constantes y variables en el tiempo o las aberraciones introducidas al focalizar haces láser con lentes astigmáticas.
