description: This dissertation examines the literary and activist histories of lesbian and queer communities in France from 1968 to the present, retracing the changing relationship between national and sexual identities. It contributes in several ways to debates about ‘homonormativity’ and ‘sexual democracy’ that have unfolded in France since the beginning of the twenty-first century, notably by bringing recent historical and sociological scholarship on the racialization of gender and sexuality into dialogue with literary studies. Sex, Race and the Epistemology of Desire puts well-established literary authors (such as Monique Wittig, Mireille Best, and Nina Bouraoui) in conversation with little-known queer writers and activists of color (such as the Groupe du 6 novembre and the Lesbiennes of color), studying processes of subject formation through which individuals come to understand their desires in relation to family structures and community belonging. Through historically and politically contextualized readings, it reflects on the fact that desire has often come to be understood through the lens of sexual identity, arguing that assumptions about the importance of visibility and “coming out” have tended to marginalize poor and racialized groups. Deconstructing the common opposition between “identitarian” and “non-identitarian” literature, it argues for a richer and more epistemologically-attentive approach to sexual and gender politics. It shows that this epistemological reframing is necessary to counteract mainstream media’s often reductive accounts of minority sexualities, particularly with respect to Islamic, Middle Eastern, or North African cultures.

description: Why do some rebel groups engage in acts of sexual violence while others do not, and what accounts for variation over time? The existing literature suggests that sexual violence should be less common among strong and cohesive groups and more prevalent in weak, disorganized groups. Because preliminary research in this field focused on systemic-level factors, only recently have some scholars begun to include rough measures of organizational dynamics in quantitative studies, and no one has yet linked multiple measures of rebel strength to a comprehensive dataset on wartime sexual violence. This thesis does so for the first time, and finds a pattern inconsistent with previous claims, showing a positive association between rebel strength and sexual violence across multiple measures in cross-rebel analyses. Case studies on the All Tripura Tiger Force and the National Patriotic Front of Liberia provide insight into how this relationship operates, and which organizational characteristics especially predispose a group to use or refrain from sexual violence. The finding that stronger rebel groups have a higher propensity toward sexual violence, controlling for numerous variables such as pre-war conditions and intensity of fighting, holds important policy implications for international organizations. Human rights groups may seek to preemptively intervene in conflicts and locations that pose a distinctive risk to the civilian population, especially where hierarchical and well-armed rebels control territory in areas outside of their support base.

description: Magnon systems used in quantum devices require low damping if coherence is to be maintained. The ferrimagnetic electrical insulator yttrium iron garnet (YIG) has low magnon damping at room temperature and is a strong candidate to host microwave magnon excitations in future quantum devices. Monocrystalline YIG films are typically grown on gadolinium gallium garnet (GGG) substrates. In this work, comparative experiments made on YIG waveguides with and without GGG substrates indicate that the material plays a significant role in increasing the damping at low temperatures. Measurements reveal that damping due to temperature-peak processes is dominant above 1 K. Damping behaviour that we show can be attributed to coupling to two-level fluctuators (TLFs) is observed below 1 K. Upon saturating the TLFs in the substrate-free YIG at 20 mK, linewidths of 1.4 MHz are achievable: lower than those measured at room temperature.

description: Sexual exploitation and abuse (SEA) by peacekeepers is a prevalent issue within UN peacekeeping missions. As of January 2015, the UN Misconduct Tracking System (MTS) began recording the nationalities of alleged SEA perpetrators. This thesis fills the gap in literature and analyzes the relationship between the nationalities of uniformed personnel from troop contributing countries (TCCs) and their subsequent SEA perpetration; furthermore, whether or not there are other factors within the TCCs, such as societal norms of gender inequality, underreporting of sexual violence and attitudes of impunity, that help explicate the variation in SEA are explored. The findings yielded alarming proportions for certain nationalities perpetrating SEA and found that TCCs were responsible for the majority of overall SEA perpetrated (from the data available); this research shows that both developing and developed countries are perpetrators of SEA and that their actions are detrimental to the UN’s broader gender-equality and peacebuilding goals. Furthermore, knowing the nationalities and the rates at which countries perpetrate SEA complicates the UN’s relationship with these TCCs, as these TCCs are in violation of international human rights norms.

description: This thesis analyzes the issue of domestic violence in the Democratic Republic of Congo that is often overlooked due to the prevalence and coverage of war-­‐related sexual violence. This paper aims to analyze the many factors that have made domestic violence so prevalent in the African region, followed by the factors unique to post-­‐conflict DRC. Furthermore, it will be evaluating the services currently provided by local and national NGOs as well as other external actors and examine whether they address or have the potential to address issues of domestic violence. Lastly, programmatic and policy recommendations for addressing domestic violence will be drawn from an examination of best practices from current interventions. The objective is for this analysis to inform future remedies for domestic violence in the DRC that do not only treat “symptoms” but also address root causes of violence against women to ensure that interventions are strategic, targeted and that change is sustainable.

description: In this paper we have tested several general numerical methods in solving the quantum billiards, such as the boundary integral method (BIM) and the plane wave decomposition method (PWDM). We performed extensive numerical investigations of these two methods in a variety of quantum billiards: integrable systens (circles, rectangles, and segments of circular annulus), Kolmogorov-Armold-Moser (KAM) systems (Robnik billiards), and fully chaotic systems (ergodic, such as Bunimovich stadium, Sinai billiard and cardiod billiard). We have analyzed the scaling of the average absolute value of the systematic error $ΔE$ of the eigenenergy in units of the mean level spacing with the density of discretization $b$ (which is number of numerical nodes on the boundary within one de Broglie wavelength) and its relationship with the geometry and the classical dynamics. In contradistinction to the BIM, we find that in the PWDM the classical chaos is definitely relevant for the numerical accuracy at a fixed density of discretization $b$. We present evidence that it is not only the ergodicity that matters, but also the Lyapunov exponents and Kolmogorov entropy. We believe that this phenomenon is one manifestation of quantum chaos.

description: Increasingly the Internet has been used by men who have sex with men (MSM) to facilitate social and sexual relationships. Finding from studies investigating the relationship between sexual risk and MSM who meet sex partners on the Internet in either venue-based (offline) and Internet-based (online) settings have been mixed. In an effort to contribute to the knowledge base on this topic, this study analyzed data from two samples of MSM recruited in New York City: Web-based HIV Behavioral Surveillance (WHBS) and National HIV Behavioral Surveillance (NHBS). The relationship between  sexual risk behaviors including unprotected anal intercourse (UAI), drug use, number of sexual partners, use of performance enhancing drugs (also known as erectile dysfunction drugs or PDE5 inhibitors), and group sex participation and mode of sex partner recruitment are examined. Univariate, bivariate, and multivariate analysis were used to examine the research questions and hypothesis.

description: We present the analytical study of stability loss and evolution of domain structure in inhomogeneous ferroelectric and ferroelastic samples for exactly solvable models. The model assumes a short-circuited ferroelectric capacitor (free ferroelastic) with two regions with slightly different critical temperatures Tc1 Tc2, where Tc1-Tc2 << Tc1, Tc2. We show that even a tiny inhomogeneity like 10-5 K results in splitting the system into domains below the phase transition temperature. At T < Tc2 the domain width a is proportional to (Tc1-T)/(Tc1-Tc2) and quickly increases with lowering temperature. The minute inhomogeneities in Tc may result from structural (growth) inhomogeneities, which are always present in real samples, and a similar role can be played by inevitable temperature gradients.

description: The three papers included in this dissertation are based on data from a larger cross-sectional survey study which explores the causes and patterns of sexual aggression by adolescent males incarcerated in residential treatment. The sample of interest included 504 male adolescents who were adjudicated delinquent and sanctioned to residential treatment for the commission of sexual and non-sexual crimes. Paper 1 includes a descriptive snapshot of the individual and family characteristics, childhood experiences, child maltreatment histories, childhood exposure to nudity and sexual activity, sexual crime characteristics, as well as non-sexual crime characteristics of juvenile sex offenders in residential treatment. Paper 2 focuses on the family characteristics and childhood experiences that predict group membership in juvenile sex offender and juvenile delinquent groups. Finally, paper 3 explores those factors associated with the severity of sexual crime as well as the frequency of general delinquency among juvenile sex offenders in residential treatment.

description: Cancer is one of the leading cause of death, worldwide. Many believe that genomic data will enable us to better predict the survival time of these patients, which will lead to better, more personalized treatment options and patient care. As standard survival prediction models have a hard time coping with the high-dimensionality of such gene expression (GE) data, many projects use some dimensionality reduction techniques to overcome this hurdle. We introduce a novel methodology, inspired by topic modeling from the natural language domain, to derive expressive features from the high-dimensional GE data. There, a document is represented as a mixture over a relatively small number of topics, where each topic corresponds to a distribution over the words; here, to accommodate the heterogeneity of a patient's cancer, we represent each patient (~document) as a mixture over cancer-topics, where each cancer-topic is a mixture over GE values (~words). This required some extensions to the standard LDA model eg: to accommodate the "real-valued" expression values - leading to our novel "discretized" Latent Dirichlet Allocation (dLDA) procedure. We initially focus on the METABRIC dataset, which describes breast cancer patients using the r=49,576 GE values, from microarrays. Our results show that our approach provides survival estimates that are more accurate than standard models, in terms of the standard Concordance measure. We then validate this approach by running it on the Pan-kidney (KIPAN) dataset, over r=15,529 GE values - here using the mRNAseq modality - and find that it again achieves excellent results. In both cases, we also show that the resulting model is calibrated, using the recent "D-calibrated" measure. These successes, in two different cancer types and expression modalities, demonstrates the generality, and the effectiveness, of this approach.

description: This ethnographic study explores diverse ways in which sexuality and social hierarchies and inequalities interact in the lives of low-income youth who were trained as peer-educators and sexual health and rights advocates in Ayacucho, Peru. It examines three central questions: 1) How are meanings about sexuality related to social hierarchies and social prestige among these youth? 2) How do quotidian manifestations of social inequity shape vulnerability of youth to sexual abuse and sexual risks, and their sexual agency to face these situations? and 3) What are the possibilities and limitations of existent sexual rights educational programs to diminish sexual vulnerability of youth facing diverse forms of inequality, such as economic, gender, ethnic and inter-generational disparities? I analyze what may be termed as the political economy of sexual vulnerability among low-income youth, and show the concrete ways in which it operates in their everyday life. Likewise, this research studies sexuality as a domain of reproduction, resignification and critique of social inequality and social hierarchies. The context is an Andean city, which in recent decades has experienced incomplete processes of democratization, and also a greater penetration of consumerism and transnational ideas and images. This study also reveals cultural logics of youth about sexual risks and complex dimensions of their sexual and gender agency. In terms of policies and programs, this research offers evidence and reflections about some challenges and limitations of a participatory sexual rights project within a context of poverty and social inequalities in urban low-income areas of Peru.

I had been in preparation to work on The Tooth of Crime before I even knew that was going to be my thesis production. My second year of graduate school was spent researching the movement in the Lower East Side in the 1970s, reading the works of Patti Smith, Arthur Rimbaud, Stéphene Mallarmé, and diving into the music of Sam Shepard’s hay days in New York City. Of course, I was doing all of this research with a new piece of work in mind. When Anne Bogart told me she would love to see my take on The Tooth of Crime, I was defiant at first. What took me two months to realize was that the show I had spent all of my time and research preparing to write already existed. Sam Shepard wrote it in 1972.

description: Sexual reproduction is an evolutionary innovation that arose 1.2 billion years ago, and in that time, has allowed a rapid diversification of species outpacing that of asexually reproducing organisms. Successful sexual reproduction in animals requires the incredible coordination of complex genetic and behavioral factors; from the most fundamental levels of ensuring correct chromosome segregation and ploidy to the most complex of behavioral mating rituals, any failure can result in a complete loss of evolutionary fitness. In this thesis, I have explored the developmental programs that function to ensure somatic sex determination, sexual differentiation, and mating behaviors in C. elegans. C. elegans is an androdiecious nematode species that has been extensively characterized in regard to the sexual dimorphism of its development, nervous system, and behavioral outputs. Sex determination pathways are widely diverged across phyla, and C. elegans has coopted a Gli family transcription factor to serve as a cell autonomous global regulator of somatic sex determination. I investigated the expression of this transcription factor, tra-1, with cellular, subcellular, sex-specific, and temporal resolution in both sexes of C. elegans and found that it is dynamically regulated to control sex determination. In contrast to the upstream sex determination pathway, genes that control downstream sexual differentiation in animals display much higher functional conservation, and many of the regulators of sexual differentiation belong to a family of transcription factors known as the DMRT family. Downstream of the tra-1 global regulator, I found that the highly conserved DMRT family gene dmd-4 acts much more specifically in adult hermaphrodites to generate sexual dimorphism at the level of the phasmid sensory neurons PHA and PHB. Furthermore, the sexual dimorphism of DMD-4 is regulated post-translationally by a ubiquitin-binding domain that I also found to be functionally conserved in the human ortholog, Dmrt3. Although these transcription factors both demonstrate the high degree of genetic control that contributes to sex determination and sexual differentiation, I also described male-specific effects of early life stress on sexual dimorphic synaptic connectivity and behavior generated by the phasmid sensory neurons, indicating that sexual differentiation is also plastic to environmental cues encountered during the life of an organism. This thesis provides insight into how genetic pathways function at multiple levels to give rise to extensive sexual dimorphism in the soma of an animal, both globally and in regard to the development on individual cells, in addition to the ways in which these genetic pathways can be modified by environmental factors and organismal life history.

description: We study symplectic numerical integration of mechanical systems with a Hamiltonian specified in non-canonical coordinates and its application to guiding-center motion of charged plasma particles in magnetic confinement devices. The technique combines time-stepping in canonical coordinates with quadrature in non-canonical coordinates and is applicable in systems where a global transformation to canonical coordinates is known but its inverse is not. A fully implicit class of symplectic Runge-Kutta schemes has recently been introduced and applied to guiding-center motion by [Zhang et al., Phys. Plasmas 21, 32504 (2014)]. Here a generalization of this approach with emphasis on semi-implicit partitioned schemes is described together with methods to enhance their performance, in particular avoiding evaluation of non-canonical variables at full time steps. For application in toroidal plasma confinement configurations with nested magnetic flux surfaces a global canonicalization of coordinates for the guiding-center Lagrangian by a spatial transform is presented that allows for pre-computation of the required map in a parallel algorithm in the case of time-independent magnetic field geometry. Guiding-center orbits are studied in stationary magnetic equilibrium fields of an axisymmetric tokamak and a realistic three-dimensional stellarator configuration. Superior long-term properties of symplectic methods are demonstrated in comparison to a conventional adaptive Runge-Kutta scheme. Finally statistics of fast fusion alpha particle losses over their slowing-down time are computed in the stellarator field on a representative sample, reaching a speed-up of the symplectic Euler scheme by more than a factor three compared to usual Runge-Kutta schemes while keeping the same statistical accuracy and linear scaling with the number of computing threads.

description: We analyze turbulent velocity signals measured by two probes in the atmosphere, both at the height of 35 meters but displaced by 40 cm nominally orthogonal to the mean wind. Choosing a suitable coordinate system with respect to that of the mean wind, we derive theoretical forms for second order structure functions, and fit them to experimental data. We show that the effect of flow anisotropy is small on the longitudinal component but significant on the transverse component. The data provide an estimate of a universal exponent from among a hierarchy that governs the decay of flow anisotropy with the scale-size.

description: To facilitate reclamation of its Pond 5 oil sands tailings pond, Suncor began construction of a full scale floating cover over the fluid tailings in the pond in January, 2010. The cover is comprised of geosynthetics overlain by petroleum coke and will function as a first step towards achieving a trafficable surface that would allow for further reclamation activities ultimately leading to the closure of the pond. A paper discussing the design of the cover and the initial construction in the winter of 2010 has been published previously. A series of field trials were conducted on the cover in the summer and fall of 2010, and the results of the field trials in addition to data and observations collected during the 2010 winter construction were used to enhance the construction methodology and improve productivity including the use of different and larger construction equipment. This paper discusses and presents these and other novel aspects of constructing a large scale floating cover on a fluid oil sand tailings pond.[All papers were considered for technical and language appropriateness by the organizing committee.]
Shaping Effects on Magnetohydrodynamic Instabilities in a Tokamak Plasma Surrounded by a Resistive Wall

description: The primary achievement of this study is the development of a new approach for optimizing the plasma shape in a tokamak fusion energy reactor. In the interest of producing the largest possible fusion power output, the shape is optimized to allow for the highest possible beta - the ratio of the fluid to magnetic pressure - that can be sustained without the onset of magnetohydrodynamic (MHD) instabilities. To this end, the study explores the beta-domain that is stabilizable by bulk plasma rotation, with rotation timescales comparable to the resistive dissipation time of the plasma tearing surfaces or of the surrounding vacuum chamber. Modern feedback control systems are able to apply external magnetic fields which are phased to emulate the effect of plasma rotation, making the technique applicable even to large tokamaks with inadequate plasma rotation.
      In order to explore how the rotationally stabilizable beta-domain is affected by plasma shaping, a new semi-analytic MHD model of a tokamak has been developed. In addition to shaped toroidal tokamak geometry, the model contains dissipative effects resulting from resistivity in both the plasma and in the vacuum-chamber wall. The inclusion of plasma and wall resistivity introduces a lower beta-limit, associated with the onset of an unstable MHD mode, which can become dominated by either resistive-plasma (tearing) or resistive-wall effects in different parts of the parameter space. The computation time for analyzing the mode stability is greatly reduced by approximating the plasma current to reside in a thin layer, a form known as a sharp-boundary model. With fast calculations that focus on the key physics of these MHD instabilities, the model is able to explore qualitative trends of rotational stabilizability over a broad range of plasma shapes.
      Results of this study predict that varying the elongation or triangularity of the plasma cross-section can lead to qualitatively different beta-limits for the rotationally stabilizable domain. As the shape is varied, the upper bound in beta for rotational stabilization is found to switch from resistive-wall dominated behavior to resistive-plasma dominated behavior. The optimal plasma shape, associated with the highest beta-limit achievable with plasma rotation, is shown to be at the crossing point between the two domains. This discovery provides a basis for understanding existing experimental results and lays the groundwork for more quantitative studies with larger codes.

Shaping Modern Japan Through Kangaku: The Case of Nishi Amane
Creators: Cooney, Owen Austin
Publisher: name: Columbia University
Year: 2011
Subjects: Asians

description: Kangaku, or Chinese learning, was the cornerstone of literature, education, and intellectual thinking in Japan for over a thousand years, even up to the end of the 19th century. In just a few decades after Japan opened to the West, however, it had receded into the background as a discipline that was considered old-fashioned and archaic (although it experienced a few revivals). What role, if any, did it play in the modernization of Japan? Was kangaku merely an obstacle to modernization, or perhaps an incidental condition of the times? Many scholars have passed it over in their studies of modern Japan. I believe, however, that if we are to truly understand the transformation Japan underwent in the late 19th century, we must examine the ways in which the Meiji Period was heavily colored by Chinese modes of thought. The purpose of this paper is to show how kangaku"”especially as a contributor to the Japanese language"”provided an intellectual framework for absorbing the alien ideas of the West while preserving and consolidating Japan's cultural identity.
Two-level system with a thermally fluctuating transfer matrix element: Application to the problem of DNA charge transfer

description: Charge transfer along the base-pair stack in DNA is modeled in terms of thermally-assisted tunneling between adjacent base pairs. Central to our approach is the notion that tunneling between fluctuating pairs is rate-limited by the requirement of their optimal alignment. We focus on this aspect of the process by modeling two adjacent base pairs in terms of a classical damped oscillator subject to thermal fluctuations as described by a Fokker-Planck equation. We find that the process is characterized by two time scales, a result that is in accord with experimental findings.

description: We investigate theoretically the dynamics of squeezed state generation in nonlinear systems possessing a transition from regular to chaotic dynamics in the limit of a large number of photons. As an example, the model of a kicked Kerr oscillator is considered. We show that at the transition to quantum chaos the maximum possible degree of squeezing increases exponentially in time, in contrast to the regular dynamics, where the degree of squeezing increases in time only power-wise. We demonstrate the one-to-one correspondence of the degree of squeezing and the value of the local Lyapunov instability rate in corresponding classical chaotic system.

description: This technical report improves and extends existing methods in the research area of audio resynthesis and retargeting and extends its usage scopes. The existing approach analyzes a musical piece for possible cut points that allow the resynthesis of a novel soundtrack by lining up the source segments according to specified rules. For the improvement of matching harmonic and rhythmic structures during cut points search, beat tracking is used as core component of this work. Segment rearrangement is improved by employing faster and better suited algorithms.

Shared Land in High Demand: Community Land Trusts in New York City

description: New York City continues to face a serious crisis in housing affordability. While the city implements a plethora of top-down planning strategies to address this crisis, some are looking to more experimental, bottom-up approaches to not only affordable housing, but larger questions of community control, empowerment, and property stewardship. As the city’s stock of public land dwindles compared to decades ago, each parcel becomes increasingly important in the fight against the unrelenting real estate industry. This paper addresses these ongoing frictions through the lens of the Community Land Trust model, a form of shared-equity ownership that seeks to decommodify property and empower local residents. Consultation of relevant literature, background of the model in the United States, local contextual research on shared equity in New York, and interviews with those most embedded in the CLT movement all inform a set of final findings and recommendations for how the city government might best approach the grassroots energy around the CLT model, and perhaps more importantly, how to not co-opt the movement.
