      • Diverse roles for black holes in string theory

        Michelson, Jeremy University of California, Santa Barbara 1999 해외박사(DDOD)

        RANK : 247343

        String theory is a theory of gravity and should therefore contain black holes. In fact, it contains a richer spectrum of solitons, known collectively as the black <italic>p</italic>-branes. Some of what string theory implies for <italic>p</italic>-branes, and what <italic>p</italic>-branes imply for string theory, is examined. To start, properties of the 11-dimensional membrane and five-brane are elucidated from the general relativistic approximation. Type IIB strings are compactified on a Calabi-Yau three-fold with Calabi-Yau valued expectation values given to the three-form field strengths. This leads to non-zero charges for the dilaton hypermultiplet. The classical potential for the dilaton multiplet is computed. It is found that supersymmetry is completely broken, except at special points in the moduli space where massless black holes appear. The moduli space metric describing the scattering of four and five dimensional black holes is computed using the method due to Manton, as adapted to black hole physics by Ferrell and Eardley. By taking the near-horizon limit of these black holes, some properties of low-dimensional anti-de Sitter spaces are obtained. In particular, the fragmentation of two-dimensional anti-de Sitter space is discussed. Some comments are also made about higher dimensional anti-de Sitter fragmentation.

      • Redefining the Romance: Classification and Community in a Popular Fiction Genre

        Michelson, Anna Northwestern University ProQuest Dissertations & T 2022 해외박사(DDOD)

        RANK : 247343

        Today’s romance fiction landscape is drastically different than the early 1980s when its community of readers and writers formalized in the Romance Writers of America and Romantic Times fan magazine. Then, romance fiction was understood to focus on “the interaction between male and female.” Today, romance depicts a variety of relationships and is primarily defined by its “happily-ever-after.” I draw on archival materials, interviews, ethnography, and content analysis to show how the boundaries of romance genre fiction – and the social meaning of romance itself – have evolved. I focus on three contested classifications (erotic romance, LGBTQ+ romance, and multicultural romance) that prompted community debates over the definition, meaning, and purpose of romance. Erotic romance pushed the boundaries of acceptable female desire by introducing explicit prose and foregrounding sexual pleasure. LGBTQ+ romance expanded the romantic paradigm beyond traditional heteronormative relationships. Multicultural romance forced the community to discuss the politics of inclusion. Advances in publishing technology and organizational change facilitated genre diversification. However, I argue that the redefinition of romance was ultimately driven by a meaning-making shift within the community. Once a private act of leisure, romance reading has taken on political significance as readers and writers see subversive political potential in “happily-ever-afters” for historically marginalized groups. Documenting forty years of romance community discourse from formalization in 1981 to possible fracture in 2021, this project shows that a genre is more than the sum of its texts – it is a social process of community negotiation and redefinition.

      • "The first and most sacred right": Religious freedom and the liberation of the Russian state, 1825--1905

        Michelson, Patrick Lally The University of Wisconsin - Madison 2007 해외박사(DDOD)

        RANK : 247343

        This dissertation examines a variety of currents in imperial Russian thought (1825-1905) that placed religious freedom, i.e. freedom of conscience, separation of church and state, and religious toleration, at the center of public debates about legislative reform and, by the turn of the century, revolutionary politics. Free communion with God, usually within the confines of a theonomous church, was commonly understood to offer each human unlimited personal sanctity as a creature created in the image and likeness of God, access to eternal, transcendental moral values around which to create an ethical community, the means by which Russia could return to the proper course of historical development, and the process by which each person could attain higher levels of consciousness. Religious freedom in this sense was thought to constitute the best means for the individual to liberate himself from bureaucratic heteronomy and restrain himself from the excesses of radical autonomy, all the while facilitating the process by which Russia entered the modern era.

      • Anticipating the Future, Influencing the Present: Assessing the Societal Implications of Emerging Technologies

        Michelson, Evan S New York University 2014 해외박사(DDOD)

        RANK : 247343

        A growing challenge for the American policymaking system is to respond effectively to a wide range of interconnected, complex, long-term science and technology issues. Simultaneously, current approaches and institutions of governance are ill suited to address these multidimensional challenges. As the next generation of innovations in science and technology is arriving at an accelerating rate, the governance system is lagging behind. This realization leads to a vital overarching consideration that steers this study: What approaches are well suited to anticipate the longer-term societal implications of emerging technologies in the 21st Century?. This study identifies and examines strategies for anticipating the longer-term societal implications of emerging technologies by way of a qualitative case study. It explores one area of technology (nanotechnology), in one particular governance system (the United States), and with a focus on one high profile non-governmental organization (NGO) involved in addressing a range of nanotechnology's societal and policy implications: the Project on Emerging Nanotechnologies (PEN). Based at the Woodrow Wilson International Center for Scholars, PEN's goal was to ensure "that as nanotechnologies advance, possible risks are minimized, public and consumer engagement remains strong, and the potential benefits of these new technologies are realized.". The conceptual framework of anticipatory governance guides the research, which offers a real-world example about how anticipatory governance applies in the nongovernmental sector and shows how this idea links to broader theoretical debates about the policymaking process. The study's main conclusion is that PEN utilized a set of interconnected strategies related to advancing foresight, operating in a boundary-spanning role, and promoting communications and public engagement in its attempt to influence, anticipate, and shape the societal implications of emerging technologies. The findings are informed by evidence from a range of sources, including document analysis, semi-structured interviews, and multiple media analyses. Finally, this study highlights a set of cross-cutting, transferable lessons that can be applied as future emerging technologies arise over time. The intention is that the insights gained from this study can help address these pressing issues as they rapidly unfold.

      • Outsiders on the Inside: Conception of Disability in Medieval Western Scandinavia

        Michelson-Ambelang, Todd The University of Wisconsin - Madison 2015 해외박사(DDOD)

        RANK : 247343

        This dissertation analyzes disability and impairment as found in the Sagas and THaettir of Icelanders. Through the analysis of impairment and disability as seen through the lens of minority and cultural studies, lexicographical studies, character studies and close readings of texts defined in the genre of Sagas and THaettir of Icelanders it is possible construct a more thorough understanding of how medieval Icelandic and Norwegian society received and perceived concepts of impairment, disability, and people who were impaired and disabled. The dissertation comprises four chapters, each one a different type of analysis of impairment and disability. Chapter 1 begins with an examination of the current trends in studies of medieval Icelandic and Norwegian culture as well as the current state of disability studies. From the disability studies standpoint, understanding the effects of impairments comes through the use of different cultural models. The second chapter consists of an examination of terms for impairment in the Sagas and THaettir of Icelanders and allows for a comprehension of different terms used and their frequency. Chapter 3 provides a character analysis of sixteen characters with impairments found in the texts; this helps to ascertain if a character with an impairment was considered disabled by society or not. Chapter 4 is a close reading of four texts, which helps establish specific views of impairment and disability, as seen through models of disability studies.

      • A reference-set approach to information extraction from unstructured, ungrammatical data sources

        Michelson, Matthew University of Southern California 2009 해외박사(DDOD)

        RANK : 247343

        This thesis investigates information extraction from unstructured, ungrammatical text on the Web such as classified ads, auction listings, and forum postings. Since the data is unstructured and ungrammatical, this information extraction precludes the use of rule-based methods that rely on consistent structures within the text or natural language processing techniques that rely on grammar. Instead, I describe extraction using a "reference set," which I define as a collection of known entities and their attributes. A reference set can be constructed from structured sources, such as databases, or scraped from semi-structured sources such as collections of Web pages. In some cases, as I shown in this thesis, a reference set can even be constructed automatically from the unstructured, ungrammatical text itself. This thesis presents methods to exploit reference sets for extraction using both automatic techniques and machine learning techniques. The automatic technique provides a scalable and accurate approach to extraction from unstructured, ungrammatical text. The machine learning approach provides even higher accuracy extractions and deals with ambiguous extractions, although at the cost of requiring human effort to label training data. The results demonstrate that reference-set based extraction outperforms the current state-of-the-art systems that rely on structural or grammatical clues, which is not appropriate for unstructured, ungrammatical text. Even the fully automatic case, which constructs its own reference set for automatic extraction, is competitive with the current state-of-the-art techniques that require labeled data. Reference-set based extraction from unstructured, ungrammatical text allows for a whole category of sources to be queried, allowing for their inclusion in data integration systems that were previously limited to structured and semi-structured sources.
