Faulkner revisited : narrating property, race, gender and history in William Faulkner's Go Down, Moses, Toni Morrison's Song of Solomon and Gloria Naylor's Mama Day

My thesis explores the formation of the subject in the novels of Faulkner’s Go Down, Moses, Toni Morrison’s Song of Solomon, and Gloria Naylor’s Mama Day. I attach the concept of property in terms of how male protagonists are obsessed with materialistic ownership and with the subordination of women who, as properties, consolidate their manhood. The three novelists despite their racial, gendered, and literary differences share the view that identity and truth are mere social and cultural constructs. I incorporate the work of Judith Butler and other poststructuralist figures, who see identity as a matter of performance rather than a natural entity. My thesis explores the theme of freedom, which I attached to the ways characters use their bodies either to confine or to emancipate themselves from the restricting world of race, class, and gender. The three novelists deconstruct any system of belief that promulgates the objectivity of truth in historical documents. History in the three novels, as with the protagonists, perception of identity, remains a social construct laden with distortions to serve particular political or ideological agendas. My thesis gives voice to African American female characters who are associated with love and racial and gender resistance. They become the reservoirs of the African American legacy in terms of their association with the oral and intuitionist mode of knowing, which subverts the male characters’ obsession with property and with the mainstream empiricist world. In this dissertation, I use the concept of hybridity as a literary and theoretical devise that African-American writers employ. In effect, I embark on the postcolonial studies of Henry Louise Gates, Paul Gilroy, W. E. B Du Bois, James Clifford, and Arjun Appadurai in order to reflect upon the fluidity of Morrison’s and Naylor’s works. I show how these two novelists subvert Faulkner’s essentialist perception of truth, and of racial and gendered identity. They associate the myth of the Flying African with the notion of hybridity by making their male protagonists criss-cross Northern and Southern regions. I refer to Mae Gwendolyn Henderson’s article on “Speaking in Tongues” in my analysis of how Naylor subverts the patriarchal text of both Faulkner and Morrison in embarking on a more feminine version of the flying African, which she relates to an ex-slave, Sapphira Wade, a volatile female character who resists fixed claim over her story and identity. In dealing with the concept of hybridity, I show that Naylor rewrites both authors’ South by making Willow Springs a more fluid space, an assumption that unsettles the scores of critics who associate the island with authenticity and exclusive rootedness.

Negros misturados: um estudo de caso sobre identidades negras em Mossoró-RN

With more or less 213.000 habitants, Mossoró is the second more developed city from the Rio Grande do Norte. The town is proclamated like the land of freedom. To so far, exist four moments in your history related with the defence of freedom that is point like truthful from so proclamation. Suchlike happenings are the first female vote on Brazil, the resistance against the Lampião s band, the worman s mutiny and the slave release in 1883, five year before the Áurea law sanction. These happenings are commemorate yearly on setember with one big theatrical event called by the freedom high. Inside this contexto of exaltation to freedom, there is one black movement by name black and beautiful. Is the present dissertation, talked about the building of black identities between the black militants of Mossoró and the dwellers from the Santo Antônio district. With such approach, we intend to think about possibles differences or likeness, how the militants and dwellers from the refered district self-calleds like blacks or not. We are understanding black identity like one process to self-affirmation done by specificities of the social context and the individual particularity. This way, the identity change into one dynamic and contextual reality, gone always by one business process against the interaction of the social actors. So we search to discuss the specificities that involve the process to building of black identities in the city of freedom

High protein flexibility and reduced hydration water dynamics are key pressure adaptive strategies in prokaryotes

Water and protein dynamics on a nanometer scale were measured by quasi-elastic neutron scattering in the piezophile archaeon Thermococcus barophilus and the closely related pressure-sensitive Thermococcus kodakarensis, at 0.1 and 40 MPa. We show that cells of the pressure sensitive organism exhibit higher intrinsic stability. Both the hydration water dynamics and the fast protein and lipid dynamics are reduced under pressure. In contrast, the proteome of T. barophilus is more pressure sensitive than that of T. kodakarensis. The diffusion coefficient of hydration water is reduced, while the fast protein and lipid dynamics are slightly enhanced with increasing pressure. These findings show that the coupling between hydration water and cellular constituents might not be simply a master-slave relationship. We propose that the high flexibility of the T. barophilus proteome associated with reduced hydration water may be the keys to the molecular adaptation of the cells to high hydrostatic pressure.

Wave impedance selection for passivity-based bilateral teleoperation

When a task must be executed in a remote or dangerous environment, teleoperation systems may be employed to extend the influence of the human operator. In the case of manipulation tasks, haptic feedback of the forces experienced by the remote (slave) system is often highly useful in improving an operator's ability to perform effectively. In many of these cases (especially teleoperation over the internet and ground-to-space teleoperation), substantial communication latency exists in the control loop and has the strong tendency to cause instability of the system. The first viable solution to this problem in the literature was based on a scattering/wave transformation from transmission line theory. This wave transformation requires the designer to select a wave impedance parameter appropriate to the teleoperation system. It is widely recognized that a small value of wave impedance is well suited to free motion and a large value is preferable for contact tasks. Beyond this basic observation, however, very little guidance exists in the literature regarding the selection of an appropriate value. Moreover, prior research on impedance selection generally fails to account for the fact that in any realistic contact task there will simultaneously exist contact considerations (perpendicular to the surface of contact) and quasi-free-motion considerations (parallel to the surface of contact). The primary contribution of the present work is to introduce an approximate linearized optimum for the choice of wave impedance and to apply this quasi-optimal choice to the Cartesian reality of such a contact task, in which it cannot be expected that a given joint will be either perfectly normal to or perfectly parallel to the motion constraint. The proposed scheme selects a wave impedance matrix that is appropriate to the conditions encountered by the manipulator. This choice may be implemented as a static wave impedance value or as a time-varying choice updated according to the instantaneous conditions encountered. A Lyapunov-like analysis is presented demonstrating that time variation in wave impedance will not violate the passivity of the system. Experimental trials, both in simulation and on a haptic feedback device, are presented validating the technique. Consideration is also given to the case of an uncertain environment, in which an a priori impedance choice may not be possible.

Design and Applications of a Decade-Spanning Terahertz Frequency Comb Spectrometer: Doppler-limited Rotational Spectroscopy of Methanol and Methanol-OD

This thesis details the design and applications of a terahertz (THz) frequency comb spectrometer. The spectrometer employs two offset locked Ti:Sapphire femtosecond oscillators with repetition rates of approximately 80 MHz, offset locked at 100 Hz to continuously sample a time delay of 12.5 ns at a maximum time delay resolution of 15.6 fs. These oscillators emit continuous pulse trains, allowing the generation of a THz pulse train by the master, or pump, oscillator and the sampling of this THz pulse train by the slave, or probe, oscillator via the electro-optic effect. Collecting a train of 16 consecutive THz pulses and taking the Fourier transform of this pulse train produces a decade-spanning frequency comb, from 0.25 to 2.5 THz, with a comb tooth width of 5 MHz and a comb tooth spacing of ~80 MHz. This frequency comb is suitable for Doppler-limited rotational spectroscopy of small molecules. Here, the data from 68 individual scans at slightly different pump oscillator repetition rates were combined, producing an interleaved THz frequency comb spectrum, with a maximum interval between comb teeth of 1.4 MHz, enabling THz frequency comb spectroscopy.

The accuracy of the THz frequency comb spectrometer was tested, achieving a root mean square error of 92 kHz measuring selected absorption center frequencies of water vapor at 10 mTorr, and a root mean square error of 150 kHz in measurements of a K-stack of acetonitrile. This accuracy is sufficient for fitting of measured transitions to a model Hamiltonian to generate a predicted spectrum for molecules of interest in the fields of astronomy and physical chemistry. As such, the rotational spectra of methanol and methanol-OD were acquired by the spectrometer. Absorptions from 1.3 THz to 2.0 THz were compared to JPL catalog data for methanol and the spectrometer achieved an RMS error of 402 kHz, improving to 303 kHz when excluding low signal-to-noise absorptions. This level of accuracy compares favorably with the ~100 kHz accuracy achieved by JPL frequency multiplier submillimeter spectrometers. Additionally, the relative intensity performance of the THz frequency comb spectrometer is linear across the entire decade-spanning bandwidth, making it the preferred instrument for recovering lineshapes and taking absolute intensity measurements in the THz region. The data acquired by the Terahertz Frequency Comb Spectrometer for methanol-OD is of comparable accuracy to the methanol data and may be used to refine the fit parameters for the predicted spectrum of methanol-OD.

Chaotic synchronization of time-delay coupled Hindmarsh–Rose neurons via nonlinear control

Chaotic synchronization of two time-delay coupled Hindmarsh–Rose neurons via nonlinear control is investigated in this paper. Both the intrinsic slow current delay in a single Hindmarsh–Rose neuron and the coupling delay between the two neurons are considered. When there is no control, chaotic synchronization occurs for a limited range of the coupling strength and the time-delay values. To obtain complete chaotic synchronization irrespective of the time-delay or the coupling strength, we propose two nonlinear control schemes. The first uses adaptive control for chaotic synchronization of two electrically coupled delayed Hindmarsh–Rose neuron models. The second derives the sufficient conditions to ensure a complete synchronization between master and slave models through appropriate Lyapunov–Krasovskii functionals and the linear matrix inequality technique. Numerical simulations are carried out to show the effectiveness of the proposed methods.

Saint-Domingue Refugees and their Enslaved Property : Abolition Societies and the Enforcement of Gradual Emancipation in Pennsylvania and New York

Ce mémoire porte sur le rôle des cercles abolitionnistes dans l’application des lois sur l’émancipation graduelle de l’esclavage dans le nord des États-Unis vers la fin du dix-huitième siècle, principalement à New York et en Pennsylvanie. Plus particulièrement, il met en lumière la façon dont ces cercles, dont les deux plus importants étaient la Pennsylvania Abolition So-ciety (PAS) et le New­York Manumission Society (NYMS), ont fait face aux centaines de réfugiés de Saint-Domingue qui sont arrivés avec leurs esclaves sur la côte est américaine pour fuir la révolution haïtienne dans les années 1790. Dans un premier temps, ce mémoire étudie l’abolition graduelle de l’esclavage dans le nord des États-Unis, débutant avec la Pennsylvanie en 1780, et la formation des cercles abolitionnistes dans les anciennes colonies anglaises. Il sera en outre question des stratégies des antiesclavagistes américains afin de promouvoir l’abolition graduelle de l’esclavage et d’empêcher le mouvement des esclaves et des noirs libres en dehors des frontières de leurs États respectifs. Il sera aussi question de leurs efforts pour resserrer davantage les clauses des lois existantes à ce sujet. Dans un second temps, dans le but de mettre en relief la contribution des cercles abolitionnistes, ce mémoire procède à une étude de cas sur la manière dont les réfugiés de Saint-Domingue ont interagi avec l’esclavage résiduel à New York et en Pennsylvanie et cherche à comprendre pourquoi leurs tentatives d’échapper aux lois sur l’émancipation graduelle se sont heurtées, à plusieurs reprises, aux stratégies des sociétés antiesclavagistes.

The Anagó Language of Cuba

This thesis investigates the socio-linguistic factors that led to the emergence of a new language in Cuba known as Anagó. This language emerged from contact between multiple dialects of the West African Yoruba language and Spanish. Language contact between the Yoruba language and Spanish took place in Cuba beginning in the nineteenth century after the introduction of large numbers of Yoruba speakers into Cuba during the trans-Atlantic slave trade. This thesis argues against the opinion that Anagó is simply a corrupted and imperfect form of Yoruba. Instead, it maintains that Anagó is a new language that emerged in Cuba and became a functional vehicle for the transmission of ideas and culture. Additionally, this study will present evidence that the Anagó speaking community was a constituent part of Cuban society since the nineteenth century, and is therefore an inextricable part of Cuban cultural patrimony. Twentieth century examples of Anagó language are examined as evidence of a vital Anagó speaking transnational community.

Taking Issue with History: Empathy and the Ethical Imperatives of Creative Interventions

The purpose of this thesis was to contribute to a dialogue that considers the relationship between history, literature, and empathy as a literary affect. Specifically, I explored sites of literature’s transformative potential as it relates to cultural studies and the ethics of deconstruction. Via a deconstructive, post-colonial reading of Toni Morrison’s Beloved and Junot Díaz’s The Brief Wondrous Life of Oscar Wao, I considered how subjects in our current socio-political moment can feel history. Emerging from a post-structurally mediated engagement with history, signification, and feeling, I argued that empathy, as it is contentiously presented in the context of deconstruction, is not necessarily a reductive or essentialist approach towards relating or “being-with” an-other. Instead, I proposed that the act of reading historiographical novels that take constructions of the Atlantic Slave Trade to task might generate an affective empathy, which could in turn engender a more empathetic relationality and way of being-in-the-world.

Rice and the making of South Carolina : an introductory essay

Originally, Carolinians grew rice on dry land, but early in the eighteenth century, cultivation spread to swampy fresh water areas. Until the 1850s, rice reigned supreme. But large-scale rice production was limited to the tidal marshes and inland swamp, while cotton became profitable statewide after the invention of the cotton gin. In its heyday, however, rice made a few hundred planters extremely wealthy. It also contributed to cross culturation and the making of Carolina as a rich cultural hybrid. In this essay, it is this aspect of rice cultivation that Professor Littlefield describes.
