    The Texture of Everyday Life: Carceral Realism and Abolitionist Speculation

    Get PDF
    Exploring the ways in which prisons shape the subjectivity of free-world thinkers, and the ways that subjectivity is expressed in literary texts, this dissertation develops the concept of carceral realism: a cognitive and literary mode that represents prisons and police as the only possible response to social disorder. As this dissertation illustrates, this form of consciousness is experienced as racial paranoia, and it is expressed literary texts, which reflect and help to reify it. Through this process of cultural reification, carceral realism increasingly insists on itself as the only possible mode of thinking. As I argue, however, carceral realism actually stands in a dialectical relationship to abolitionist speculation, or, the active imagining of a world without prisons and police and/or the conditions necessary to actualize such a world. In much the same way that carceral realism embeds itself in realist literary forms, abolitionist speculation plays a constitutive role in the utopian literary tradition. In order to elaborate these concepts, this dissertation begins with a meta-consideration of how cultural productions by incarcerated people are typically framed. Building upon the work of scholars and incarcerated authors’ own interventions in questions of consciousness, authorship, textual production, and study, this chapter contrasts that typical frame with a method of abolitionist reading. Chapter two applies this methodology to Edward Bunker’s 1977 novel The Animal Factory and Claudia Rankine’s 2010 poem Citizen in order to develop the concept of carceral realism and demonstrate how it has developed from the 1970s to the present. In order to lay out the historical foundations of the modern prison, chapter three looks back to the late 18th century and situates the emergence of the penitentiary within debates regarding race, citizenship, and state power. Returning to the 1970s, chapter four investigates the role universities have played in the formation of carceral realism and the complex relationship Chicanos and Asian Americans have to prisons and police by analogizing the institutionalization of prison literary study to the formation of ethnic studies. Chapter five draws this project to a conclusion by developing the concept of abolitionist speculation, or the active imagining of a world without prisons or the police and/or the conditions necessary to realize such a world, which I identify as both a constitutive generic feature of utopian literature and something that exceeds literature altogether. In doing so, this dissertation establishes an ongoing historical relationship between social reproduction of prisons and literary forms that cuts across time, geography, race, gender, and genre

    Evaluating automated and hybrid neural disambiguation for African historical named entities

    Documents detailing South African history contain ambiguous names. Ambiguous names may be due to people having the same name or the same person being referred to by multiple different names. Thus when searching for or attempting to extract information about a particular person, the name used may affect the results. This problem may be alleviated by using a Named Entity Disambiguation (NED) system to disambiguate names by linking them to a knowledge base. In recent years, transformer-based language models have led to improvements in NED systems. Furthermore, multilingual language models have shown the ability to learn concepts across languages, reducing the amount of training data required in low-resource languages. Thus a multilingual language model-based NED system was developed to disambiguate people's names within a historical South African context using documents written in English and isiZulu from the 500 Year Archive (FHYA). The multilingual language model-based system substantially improved on a probability-based baseline and achieved a micro F1-score of 0.726. At the same time, the entity linking component was able to link 81.9% of the mentions to the correct entity. However, the system's performance on documents written in isiZulu was significantly lower than on the documents written in English. Thus the system was augmented with handcrafted rules to improve its performance. The addition of handcrafted rules resulted in a small but significant improvement in performance when compared to the unaugmented NED system

    Stress detection in lifelog data for improved personalized lifelog retrieval system

    Stress can be categorized into acute and chronic types, with acute stress having short-term positive effects in managing hazardous situations, while chronic stress can adversely impact mental health. In a biological context, stress elicits a physiological response indicative of the fight-or-flight mechanism, accompanied by measurable changes in physiological signals such as blood volume pulse (BVP), galvanic skin response (GSR), and skin temperature (TEMP). While clinical-grade devices have traditionally been used to measure these signals, recent advancements in sensor technology enable their capture using consumer-grade wearable devices, providing opportunities for research in acute stress detection. Despite these advancements, there has been limited focus on utilizing low-resolution data obtained from sensor technology for early stress detection and evaluating stress detection models under real-world conditions. Moreover, the potential of physiological signals to infer mental stress information remains largely unexplored in lifelog retrieval systems. This thesis addresses these gaps through empirical investigations and explores the potential of utilizing physiological signals for stress detection and their integration within the state-of-the-art (SOTA) lifelog retrieval system. The main contributions of this thesis are as follows. Firstly, statistical analyses are conducted to investigate the feasibility of using low-resolution data for stress detection and emphasize the superiority of subject-dependent models over subject-independent models, thereby proposing the optimal approach to training stress detection models with low-resolution data. Secondly, longitudinal stress lifelog data is collected to evaluate stress detection models in real-world settings. It is proposed that training lifelog models on physiological signals in real-world settings is crucial to avoid detection inaccuracies caused by differences between laboratory and free-living conditions. Finally, a state-of-the-art lifelog interactive retrieval system called \lifeseeker is developed, incorporating the stress-moment filter function. Experimental results demonstrate that integrating this function improves the overall performance of the system in both interactive and non-interactive modes. In summary, this thesis contributes to the understanding of stress detection applied in real-world settings and showcases the potential of integrating stress information for enhancing personalized lifelog retrieval system performance

    Comparing the production of a formula with the development of L2 competence

    Get PDF
    This pilot study investigates the production of a formula with the development of L2 competence over proficiency levels of a spoken learner corpus. The results show that the formula in beginner production data is likely being recalled holistically from learners’ phonological memory rather than generated online, identifiable by virtue of its fluent production in absence of any other surface structure evidence of the formula’s syntactic properties. As learners’ L2 competence increases, the formula becomes sensitive to modifications which show structural conformity at each proficiency level. The transparency between the formula’s modification and learners’ corresponding L2 surface structure realisations suggest that it is the independent development of L2 competence which integrates the formula into compositional language, and ultimately drives the SLA process forward

    The Perception of K-12 Instrumental Directors in Low-Income Areas on Virtual Learning with Skill Development and Retention

    Get PDF
    Due to the extreme measures taken to protect students from COVID-19 during the pandemic, schools closed their doors, and educators struggled to continue teaching through virtual learning platforms. Performance-based classrooms were encouraged to discover new methods and strategies to motivate students to thrive even though face-to-face rehearsals were restricted. This study examined the experiences secondary music education instrumentalists faced while attempting to utilize synchronous and asynchronous instruction in a 100 percent virtual performance-based environment. This study aimed to understand the negative and positive effects placed on secondary instrumentalists’ performance abilities, fundamental development, and participation/retention since the introduction of virtual learning in low-income areas. The focus of this study also examined the possible benefits of enhancing pedagogical skills through the addition of technological advances to push instrumental instruction and performances on the secondary level. This study followed a qualitative hermeneutic phenomenology design. Music educators in low-income DeKalb County communities were interviewed for this study. Participants were requested to share their perspectives and experiences of performance-based virtual learning and results. The study raised the need for future discussions to create and implement a state and national virtual music education guideline that would assist music educators in turning a devastating situation into a blessing for all art programs and their stakeholders
