Prisoners of Style: Slavery, Ethics, and the Lives of American Literary Characters
Creators: Parra, Jamie Luis
Publisher: name: Columbia University
Year: 2016
Subjects: Characters and characteristics in literature
Slavery in literature
American literature
African Americans

description: This dissertation reconsiders the relationship between fiction and slavery in American literary culture.  “Prisoners of Style” shows how writers from the middle of the nineteenth to the middle of the twentieth century, including Hannah Crafts, Mark Twain, Charles Chesnutt, and William Faulkner, wrestled with enslavement.  They found it not only a subject to be written about, but also a problem of characterization.  Slavery and the ontological sorcery through which it produced a new kind of individual—the individual who is also a thing—led these authors to rethink basic formal assumptions about realist fiction, especially about what constitutes a literary character.  The writers I discuss did not set out to argue for the slave’s humanity or to render her interiority, but instead sought to represent the systematic unmaking of black personhood perpetrated by the laws and institutions that governed chattel slavery in the US.  They set out to reveal the ideological violence perpetrated against enslaved blacks, and they did so by writing characters who embodied the categorical uncertainty of the slave, characters who were not allegories for real, full people.  The tradition of writing I describe does not represent the fullness of enslaved “persons”; instead it renders something far more abstract: the epistemology that undergirded enslavement—those patterns of thought that preconditioned slavery itself.
      	The authors I study understood fictionality as a thorny ethical, epistemological, and political problem.  In my chapter on Crafts, for example, I look at The Bondwoman’s Narrative alongside a set of non-fiction texts about Jane Johnson, the slave who preceded her in John Hill Wheeler’s household.  Reading the novel against legal documents, pamphlets, and histories about Johnson and her escape from Wheeler, the chapter explores what fiction could do that these other modes of writing could not.  In moments of sleep, amnesia, and daydreaming, Crafts resists the normative logic of subjecthood and individual rights that underpins the representations of Johnson.  In the second half of the project, I demonstrate the significance of fictionality to American literary realism’s evolution into modernism.  The final chapter, on Faulkner, places two of his Yoknapatawpha novels within the context of his interest in modernist painting and sculpture.  Work by Picasso, Matisse, and other visual artists inspired his concern with surfaces and flatness, leading to a meditation on artifice that runs throughout his major novels. I argue that his flatness—his insistence on the non-referential quality of fiction—is crucial for understanding his characterization and philosophy of history history, in particular the history of Southern plantation slavery.

description: The use of new building materials and new building methods for reconstruction of housing accomodations in destroyed cities raises the question of sound-insulation to a very important matter, especially in consideration of the density of population and the increasing number of sound producing elements, such as wireless, traffic, etc.
The subject of building acoustics still offers many problems which should be solved by close cooperation of scientific research work and practical experience.
Latest results in sound-insulation of walls and ceilings, which were obtained in the acoustical department of the "Institut für Baustoffkunde und Materialprüfung der Technischen Hochschule Braunschweig" demonstrate that the subject is being thoroughly worked at. If the great number of existing problems is to be solved in the interest of the building practice as well as in the interest of the population, research on basic conditions must be combined with research for desirable improvements.

description: We give a review of theoretical and experimental results concerning the magnetic susceptibility of the Weyl, Dirac, and nodal-line semimetals. In particular, dependences of the susceptibility on the chemical potential, temperature, and magnitude of the magnetic field are discussed. The presented results show that the specific features of the magnetic susceptibility can serve as a hallmark of the topological semimetals, and hence magnetic measurements can be useful in investigating these materials.

description: Radio holography is the preferred method for the assessment of the surface accuracy and alignment of high gain microwave and millimeter/sub-millimeter-wave antennas and relay optics chains used in radio astronomy. High signal to noise ratio measurements using transmitters in the near-field are used to assess and correct small scale deviations. Elevation dependent large scale deformations are studied using measurements on celestial sources. A review of the methods used will be presented using experience primarily with the sub-millimeter wavelength antennas of the Submillimeter Array (SMA).
Closed-Flux Solutions to the Constraints for Plane Gravity Waves
Creators: name: Neville, Donald E.

Year: 1996
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: The metric for plane gravitational waves is quantized within the Hamiltonian framework, using a Dirac constraint quantization and the self-dual field variables proposed by Ashtekar. The z axis (direction of travel of the waves) is taken to be the entire real line rather than the torus (manifold coordinatized by (z,t) is RxR rather than $S_1$ x R). Solutions to the constraints proposed in a previous paper involve open-ended flux lines running along the entire z axis, rather than closed loops of flux; consequently, these solutions are annihilated by the Gauss constraint at interior points of the z axis, but not at the two boundary points. The solutions studied in the present paper are based on closed flux loops and satisfy the Gauss constraint for all z.

description: In stochastic optimization, using large batch sizes during training can leverage parallel resources to produce faster wall-clock training times per training epoch. However, for both training loss and testing error, recent results analyzing large batch Stochastic Gradient Descent (SGD) have found sharp diminishing returns, beyond a certain critical batch size. In the hopes of addressing this, it has been suggested that the Kronecker-Factored Approximate Curvature (\mbox{K-FAC}) method allows for greater scalability to large batch sizes, for non-convex machine learning problems such as neural network optimization, as well as greater robustness to variation in model hyperparameters. Here, we perform a detailed empirical analysis of large batch size training %of these two hypotheses, for both \mbox{K-FAC} and SGD, evaluating performance in terms of both wall-clock time and aggregate computational cost. Our main results are twofold: first, we find that both \mbox{K-FAC} and SGD doesn't have ideal scalability behavior beyond a certain batch size, and that \mbox{K-FAC} does not exhibit improved large-batch scalability behavior, as compared to SGD; and second, we find that \mbox{K-FAC}, in addition to requiring more hyperparameters to tune, suffers from similar hyperparameter sensitivity behavior as does SGD. We discuss extensive results using ResNet and AlexNet on \mbox{CIFAR-10} and SVHN, respectively, as well as more general implications of our findings.

description: Sociology is only just on its way to become an exact science. The social and political situation today calls for qualified knowledge about the structure of society. It is shown, by examples, that sociology as yet has merely scratched the surface of problems. The activities of statistical departements are guided more by economic than sociological points of view. In adapting their records to the needs of sociology, they would enable the sociologist to become as useful to those in political authority as the economist has been these 30 years.

description: By measuring electron tunneling between a ferromagnet and individual energy levels in an aluminum quantum dot, we show how spin-resolved quantum states can be used as filters to determine spin-dependent tunneling rates. We also observe magnetic-field-dependent shifts in the magnet's electrochemical potential relative to the dot's energy levels. The shifts vary between samples and are generally smaller than expected from the magnet's spin-polarized density of states. We suggest that they are affected by field-dependent charge redistribution at the magnetic interface.

description: We study systematically the quantum corrections to a weakly interacting Bose-Einstein condensate with spin-orbit coupling. We show that quantum fluctuations, enhanced by the spin-orbit coupling, modify quantitatively the mean-field properties such as the superfluid density, spin polarizability, and sound velocity. We find that the phase boundary between the plane wave and zero momentum phases is shifted to a smaller transverse field. We also calculate the Beliaev and Landau damping rates and find that the Landau process dominates the quasiparticle decay even at low temperature.

description: We present detailed calculations of the quasinormal modes of Reissner-Nordstrom black holes. While the first few, slowly damped, modes depend on the charge of the black hole in a relatively simple way, we find that the rapidly damped modes show several peculiar features. The higher modes generally spiral into the value for the extreme black hole as the charge increases. We also discuss the possible existence of a purely imaginary mode for the Schwarzschild black hole: Our data suggest that there is a quasinormal mode that limits to $ωM = -2i$ as $Q\to 0$.

description: 70 p. c. of the unemployed fall to the laender Schleswig-Holstein, Niedersachsen, and Bavaria. To these laender too fall 67 p. c. of the total of wage earners employed in agriculture and forestry, and about five millions in the seven millions of refugees. The unemployed cannot find jobs but in industry, trades, and commerce, i. e. mainly in the laender Nordrhein-Westfalen, Wuerttemberg, Hessen, Hamburg and Bremen. Consequently nothing will stop unemployment but a state-controlled housing and building scheme. Here is the key to solve the problems concerning labour, welfare, and public health. To solve the housing problem practically to find England has taken novel approaches of her own during the past thirty years. In Germany it is escentide a similar solution of removing the housing, and labour, calamities or a social catastrophe cannot be avoided.

Restoring access to fish habitat through the design and construction of two fishways at Huckleberry Mine
Creators: name: Poulton, T. L. S.
Publisher: name: The University of British Columbia
Year: 2014

description: Creek M is a short, high-gradient creek located on the south side of Tahtsa Reach in Ootsa Lake (Nechako Reservoir) near Houston, British Columbia. This creek was barren of fish until 1996, when Huckleberry Mines Ltd. implemented a habitat-compensation plan to offset prospective losses of fish habitat associated with mine development. The goal of this plan was to allow upstream passage of fish from Tahtsa Reach throughout the creek to a headwater pond located approximately 425 metres (m) upstream. Compensation structures within the creek consisted of three fishways comprised of log-steps (i.e., weirs) lined with geotextile and anchored with rock fill. Annual fish surveys documented the failure over time of many log-step structures, precluding fish passage. In 2012 and 2013, remedial works were undertaken to re-establish upstream fish passage for juvenile and adult rainbow trout in Creek M. New fishways were designed to be more robust, to function over a range of flows, and to meet specific requirements of migrating rainbow trout.
Orbital Torque: Torque Generation by Orbital Current Injection

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We propose a mechanism of torque generation by injection of an orbital current, which we call $\textit{orbital torque}$. In a magnetic bilayer consisting of a nonmagnet (NM) and a ferromagnet (FM), we consider a situation where the spin-orbit coupling (SOC) is present only in the FM. Although the SOC is absent in the NM, the orbital Hall effect can arise in the NM. When the resulting orbital Hall current is injected to the FM, the SOC of the FM converts the orbital angular momentum into spin, which exerts torque to the magnetization of the FM. Remarkably, even for small SOC strength comparable to that of $3d$ FMs, the orbital torque can be comparable to the spin torque induced by the spin Hall effect of the NM with strong SOC. This provides a way to experimentally probe the OHE and opens a new venue to achieving spin-torque devices based on light elements that exhibit gigantic orbital response. Experimental implications are discussed.

description: We generalize previous work on the energy-momentum tensor-distribution of the Kerr geometry by extending the manifold structure into the negative mass region. Since the extension of the flat part of the Kerr-Schild decomposition from one sheet to the double cover develops a singularity at the branch surface we have to take its non-smoothness into account. It is however possible to find a geometry within the generalized Kerr-Schild class that is in the Colombeau-sense associated to the maximally analytic Kerr-metric.

description: This paper reports on observations of the D-lines of sodium in the twilight made at Braunschweig in 1941. The sudden decrease of intensity of the sodium lines in the evening twilight and the sudden enhancement in the morning twilight was photographed in short intervals with a spectograph of high aperture in two directions (zenith and horizon). The evaluations of the spectra show that the D-lines must be excited by ultraviolet light of the sun, for which the ozone-layer of the upper atmosphere is not transparent. The upper limit of this screening ozone layer was determined to 54 ± 3 km. The sodium layer shows also a sharp upper limit at 118 ± 2,5 km. Occasional observations show a not well defined under limit of the sodium layer at 106,5 ± 6 km corresponding to a thickness of 11,5 ± 6,5km for the light-emitting sodium layer. The possible errors are discussed thorougbly. The obtained values are in good agreement with reults of other authors.

description: We study a finite spin-$\frac{1}{2}$ Ising chain with a spatially alternating transverse field of period 2. By means of a Jordan-Wigner transformation for even and odd sites, we are able to map it into a one-dimensional model of free fermions. We determine the ground-state energies in the positive- and negative-parity subspaces (subspaces with an even or odd total number of down spins, respectively) and compare them in order to establish the ground-state energy for the entire Hamiltonian. We derive closed-form expressions for this energy gap between the different parity subspaces and analyze its behavior and dependence on the system size in the various regimes of the applied field. Finally, we suggest an expression for the correlation length of such a model that is consistent with the various values found in the literature for its behavior in the vicinity of critical points.

description: The magnetic order-disorder layering transitions of a spin-1 Ising model are investigated, under the effect of a variable surface crystal field $Δ_{s}$, using the mean field theory. Each layer $k$, of the film formed with $N$ layers, disorders at a finite surface crystal field distributed according to the law $Δ_k=Δ_s/k^α$, $k=1,2,...,N$ and $α$ being a positive constant. We have established the temperature-crystal field phase diagrams and found a constant tricritical point and a reentrant phenomenon for the first $k_0$ layers. This reentrant phenomenon is absent for the remaining $N-k_0 $ layers, but the tricritical points subsist and depend not only on the film thickness but also on the exponent $α$. On the other hand, the thermal behaviour of the surface magnetisation for a fixed value of the surface crystal field $Δ_{s}$ and selected values of the parameter $α$ are established.

open source community

description: The aim of this workshop is to provide a space where senior staff involved in strategic planning within their organisations can explore how digital repositories can contribute a key component in the implementation of a digital strategy. Furthermore, the workshop will look at how engagement with, and participation in, an external open-source community can be a part of that contribution. The workshop will use experience from Partners and Adopters within the Samvera Community to provide use cases relevant to these themes. Attendees are encouraged to make use of this workshop to clarify their own needs, discover how Partners and Adopters of the Samvera Community have addressed these needs, and explore how they have aligned their own repository developments with local strategic planning. Alongside delivery of content within the workshop there will be a focus on discussion and Q&A to help identify how to address strategic needs through sharing of experiences.

description: We present a novel mechanism for the production of primordial black holes (PBHs). The mechanism is based on a period of thermal inflation followed by fast-roll inflation due to tachyonic mass of order the Hubble scale. Large perturbations are generated at the end of the thermal inflation as the thermal inflaton potential turns from convex to concave. These perturbations can lead to copious production of PBHs when the relevant scales re-enter horizon. We show that such PBHs can naturally account for the observed dark matter in the Universe when the mass of the thermal inflaton is about $10^6\,$GeV and its coupling to the thermal bath preexisting the late inflation is of order unity. We consider also the possibility of forming the seeds of the supermassive black holes. In this case we find that the mass of the thermal inflaton is about $1\,$GeV, but its couplings have to be very small, $\sim 10^{-7}$. Finally we study a concrete realisation of our mechanism through a running mass model.

description: This article explores musical bodies that connect people beyond historical and geopolitical boundaries. Drawing a case from the Ogasawara Islands, Japan, it explicates how musical bodies embody multiple pasts of this small island community. Since the first settlement in 1830, the Ogasawara Islanders have suffered various hardships, including Japanese colonisation (1870s), discrimination at home, forced evacuation during the Pacific War (1941-1945), segregated life under the US Navy (1946-1968), and reversion to Japanese administration (1968). Reflecting the entangled history, various musical genres are present in Ogasawara today, including taiko drumming, Micronesian dance, and hula. The variety of musical activities appears to represent a fracturing of memories and identity. However, I argue that these musical activities rather embody multiple bonds of Ogasawara with many others. Here, musical bodies take a significant role. The performing bodies produce corporeal experiences of Ogasawara’s multiple pasts, and affirm extended relationships of this small/remote community. By referring to such concepts as “historical reenactment” and “historically informed performance,” the article identifies Ogasawara within a plurality of histories and cultures that transcends our conventional concepts of history, culture, and the nation.

Proposal of a realistic stochastic rotor engine based on electron shuttling

description: We propose and analyse an autonomous engine, which combines ideas from electronic transport and self-oscillating heat engines. It is based on the electron-shuttling mechanism in conjunction with a rotational degree of freedom. We focus in particular on the isothermal regime, where chemical work is converted into mechanical work or vice versa, and we especially pay attention to use parameters estimated from experimental data of available single components. Our analysis shows that for these parameters the engine already works remarkably stable, albeit with moderate efficiency. Moreover, it has the advantage that it can be up-scaled to increase power and reduce fluctuations further.

description: In this thesis I will show that, by leveraging efficient data structures and algorithms for indexing and secure computation, we can create practical systems for anonymous and private search, communication, and content distribution.  I will improve and extend existing work in private search, which only addresses the problem where a client stores his own data encrypted on a server and wishes to be able to search his records remotely without revealing the their content.  I do so by addressing a broader scenario, in which one or more servers store their own data, and a number of users wish to be able to issue queries across these records, without the server learning about the types of queries users are running, and without users learning anything about the remote databases besides the results of their searches.
      I also improve upon the field of anonymous communication systems, where prior systems focused on addressed communication in a unicast setting.  I will discuss how we can create anonymous communication systems that work on a publish-subscribe basis, allowing communication to reach many people while solving the issue of how to establish communication without prior relationships.
      Next, I will discuss anonymous credential systems, and how to make them feasible for real-world scenarios.  These systems can be useful for anonymously enforcing policies and managing privileges on a per-user basis.  Our final challenge is to provide a scalable anonymous communication system that can deliver our queries while maintaining our privacy requirements.  I will do this using a publish-subscribe architecture.
      I will show how all of these advancements can be accomlished by leveraging Bloom Filters, Onion Routing, Re-routable Encryption, and Yao Garbled Circuits to create anonymity preserving systems that operate in real time.
Privatization and decentralization of a public service: Solid Waste Management in Kathmandu

Decentralization in government--Evaluation

description: Solid Waste Management (SWM) system in Kathmandu, Nepal was looked over by Kathmandu Metropolitan City (KMC). The three stages of SWM systems: collection, transportation, and disposal were all under its purview. Once, the waste was out of people’s personal property; then the waste would be the property of the city. With the gap in the amount of waste generation and the amount of waste that KMC was treating, there was a rise of privatization in the SWM system which led to the decentralization of SWM systems.

The primary objectives of this study are:
• to examine the effects and impacts of decentralization in the SWM systems in Kathmandu on the city, the people and the systems themselves,
• to evaluate the drivers of SWM system operations, and
• to analyze the efficiency of any SWM system and its operation in Kathmandu.

With the qualitative approach of systematic observation and analysis through interviews of key players in the multiple systems, this study found that SWM in Kathmandu is seldom collaborative. There is instead an added financial expense on the locals for their desire of a clean neighborhood. Furthermore, findings revealed that there is a lack of vision and contingency plans for KMC’s system and a lack of regulation for multiple private sector operations. This study concludes with recommendations for SWM systems and practices and the implications for planning research in SWM.
Privatizing the Metro Card: Transportation Equity in an Open-Loop Smartcard Fare Payment System

description: The unbanked – individuals who lack a bank account with a mainstream financial institution – are one of the more broadly disadvantaged groups in American society. There is a great deal of demographic overlap between the unbanked as a cohort and other marginalized groups, notably undocumented immigrants, low-income Blacks and Latinos and non-native English speakers. These groups are an important constituency for transportation agencies in that they are more likely to travel by transit than other Americans. As many transit agencies transition their fare payment systems to radio frequency identification (RFID)-based, “contactless” smartcard or open payment technology linked to a rider’s bank account, there are growing opportunities to enhance multi-modalism in passenger trips, reduce operations costs, increase system profitability, and expand access to fare payment media. However, due to equity requirements of the Civil Rights Act, transit agencies must ensure that the smartcard technology also accommodates the unbanked. Ensuring that transit fare payment systems adequately serve the unbanked requires an assessment of New York’s unbanked population beyond that which is available in current academic literature. A 2011 study from the NYC Department of Consumer Affairs identified several New York City neighborhoods with the highest proportions of unbanked and underbanked residents. Through intercept surveys in two of these majority-unbanked neighborhoods – Fordham (Bronx) and Bushwick (Brooklyn) – this study attempts to clarify the travel behavior and fare payment characteristics of the un(der)banked. In addition, this study investigates potential fare policy alternatives in an open payment system that would adequately accommodate the transportation needs of the unbanked. To articulate policy recommendations to meet this objective, this study includes structured interviews with transit fare policy experts in the public, private and nonprofit sectors. These interviews explored how transit agencies can select the most appropriate fare payment technology; effectively partner with retailers and alternative financial services (AFS) to make its new fare payment medium accessible to un(der)banked communities; and establish performance metrics to monitor the fare payment system’s long-term equity.

description: The operator realizing a Dehn twist in quantum Teichmuller theory is diagonalized and continuous spectrum is obtained. This result is in agreement with the expected spectrum of conformal weights in quantum Liouville theory at c>1. The completeness condition of the eigenvectors includes the integration measure which appeared in the representation theoretic approach to quantum Liouville theory by Ponsot and Teschner. The underlying quantum group structure is also revealed.

description: This research addresses the recent policy shift in the provision of affordable housing in New York, namely the privatization of this “public good” during the early government-funded NYCHA public housing to the more recent public-private partnerships and fully privately funded and owned affordable housing units. The author addresses the following questions:  How could privatization benefit NYCHA housing given the ever increasing demand for more units and better quality? What strategies could help NYCHA provide functioning housing units more efficiently?
The history of affordable housing policy is studied along with comparison of typical publicly funded and managed NYCHA housing and public-private partnered affordable housing. NYCHA public housing is mostly funded by federal or city subsidy. The study examines the possible privatization of NYCHA development and looks into privatized affordable development to find strategies for improvement of space, quality and service. Recommendations are made based on results of quantitative analysis, site observation, and theory of public goods and privatization.  These recommendations are also based on interview findings, interviews with residents, developers and housing officials.
