CRISIS, FORMULATION AND AUTOBIOGRAPHICAL INTIMACY IN 1950s AMERICA
Year of Dissertation:
Crisis, Formulation, and Autobiographical Intimacy in 1950s America explores how critical circumstances of historical and personal significance can inspire and direct autobiographical production. I concentrate on Alfred Kazin's A Walker in the City (1951), Vladimir Nabokov's Speak, Memory (1967), and Robert Lowell's Life Studies (1959), three American autobiographies whose first or final versions were produced in the nineteen fifties, decade marked by a surge of autobiographical texts and genres in the United States and the emergence of autobiographical theory in France. Engaging with Robert Jay Lifton's theory of trauma, namely the concept of formulation, I investigate how the relationship between the self and the world is fostered in the wake of a crisis as reflected in autobiographical performance unfolding through drafting, meta-writing, revision, publication, and republication. As I trace the evolution of the texts, I find each author's persistent attempt to forge a connection to the multiple relational others, including the reader, implicated in the autobiographical act. I argue that the prospect and process of gaining this connection - at once troubling and rewarding - tend to stimulate writing and facilitate revision as the writers cross the threshold from the pre-war to the post-war world and grapple with the shifts occurring in their private lives. In the course of writing and re-writing their autobiographies, Kazin, Nabokov, and Lowell develop a special kind of closeness with their relational others that arises from the interrelated acts of identification, projection, and narration. Looking at autobiographical process (revision, textual versioning) rather than merely product (final text), I illustrate how these acts are enhanced, qualified, or reversed as they are repeated. They produce autobiographical intimacy: forged by various forms of interaction(s), it is a virtual space whereby participants of the autobiographical act foster communication, reciprocity, and potentially trust - productively or otherwise.
The Music and Multiple Identities of Kurdish Alevis from Turkey in Germany
Year of Dissertation:
This dissertation investigates the experiences of Kurdish Alevis, currently living in Germany, who trace their background to locations within the boundaries of the Republic of Turkey. I argue that music has been a particularly important mode through which Kurdish Alevis in Germany have articulated collective histories and have fashioned narratives of belonging and multiple and sometimes contradictory identities. The subjects of my research are immigrants and refugees who are ethnically Kurdish and whose religion is Alevi, an Anatolian religion whose relations to both Sunni and Shi'a Islam are historically controversial. They speak Turkish along with Kurdish, in most cases are Turkish and German citizens living in and around Cologne, Germany, and have family members in Istanbul, Turkey. Kurdish Alevis struggled against being labeled with certain identities, such as Turkish and Muslim within the larger immigrant pool from Turkey. At the same time, many of them have striven for their collective identities, namely Kurdish and Alevi, primarily in the last two decades. Music has been an integral part of their efforts. I argue that, in the last two decades, a new transnational field has emerged for Kurdish Alevi immigrants and refugees in Germany and by extension in Turkey, opening spaces for realignment around various and fluctuating loyalties with respect to ethnic, political, and social modes of belonging. This work is an investigation of the music of this ethno-religious double minority group in their second and third homelands.
Acculturation of children of Bangladeshi immigrants in New York City: Intergenerational perspectives and alternative trajectories
Year of Dissertation:
This study explores the acculturation experiences of thirty-three Bangladeshi second generation youths in New York City through in depth interviews. The researcher has observed and recorded interactions between youths and parents in the natural setting of their homes. The findings of this qualitative study, conducted in the tradition of grounded theory, are presented in four analytic categories: crossroads of acculturation dividing immigrant parents and children; gendered socialization of Bangladeshi children in traditional patriarchal families; influence of New York City on acculturation of these children; and their ethnic self-identity trajectories and repertoires. These frameworks reveal how intentionality and secondary socialization impinge on intergenerational cultural continuity to transform new New Yorkers; unlike their parents, the children renounce ethnocentricity, native country affiliation, and patriarchal value system. Bangladeshi immigrant parents contribute to the city's increasing diversity by remaking the city through burgeoning ethnic enclaves, in which they hold fast to cultural traditions. In contrast, their children remake the city and the city remakes them. They embrace a plurality of perspectives and the values of an egalitarian society. Because all the young informants are New Yorkers, their acculturation experiences are shaped in a diverse and multi-ethnic setting. They contextualized these experiences in comparison with actual and potential second generation immigrant experiences in "the mid-west" or upstate New York, isolated from a vibrant ethnic enclave and multi-cultural community. The study has also developed mid-level theories: immigrant children's acculturation is attributed to push-pull factors, shift from primary to secondary socialization, and intentionality compared with parents. Bangladeshi girls question gendered socialization and reject their parent's role in contracting arranged marriages more so than the boys. They benefit from the protection of stringent parental oversight, while boys' freedoms lead, in some instances, to antisocial behavior. In addition, the length of children's self-identity trajectories is matched by the level of complexity in their identity repertoires. A key implication for social work practice is that Bangladeshi parents reject services from members of their own community because they do not want exposure of parent-child conflicts within the ethnic enclave. Community-based services are unlikely to benefit families who need to resolve intergenerational discord.
Studies in Volatility
Year of Dissertation:
This dissertation consists of five chapters that focus on the price discovery role of equity markets and examine the evolution of intraday stock price volatility as a key measure of market quality. Using six differentiated measures of intraday volatility (that mostly focus on the opening half-hour of trading), all common stocks listed at three stock exchanges with varying levels of fragmentation are analyzed: NYSE and NASDAQ stocks over the period 1993-2012, and Istanbul Stock Exchange (ISE) stocks over the period 2000-2011. The results on the evolution of intraday volatility presented in Chapters 2 and 3 indicate the following: In 1993, opening period volatility for NYSE listed stocks was considerably lower than it was for NASDAQ stocks. Over the years that followed, NASDAQ's opening volatility fluctuated widely, but has exhibited neither an upward nor a downward trend. For the NYSE, on the other hand, opening volatility has risen appreciably; now, and in recent years, its pattern closely matches that of NASDAQ. ISE listed stocks exhibited much higher intraday volatility at the beginning of the sample period (in 2000), but it decreased over the next twelve years. Recognizing the differences in the evolution of fragmentation in these three markets, Chapter 4 presents an analysis of the relation between stock-level fragmentation and the corresponding intraday volatility for the U.S. stocks. The chapter documents a positive and persistent relationship between fragmentation and opening period volatility. In light of the results presented in this dissertation, it is important for market participants to recognize the complexities of the price discovery process in the marketplace and to target on developing more efficient trading mechanisms that will improve the quality of prices. These improvements will benefit the participants in a market as well as the broader economy that they constitute.
SCHEDULING AND RESOURCE ALLOCATION IN WIRELESS SENSOR NETWORKS
Year of Dissertation:
In computer science and telecommunications, wireless sensor networks are an active research area. Each sensor in a wireless sensor network has some pre-defined or on demand tasks such as collecting or disseminating data. Network resources, such as broadcast channels, number of sensors, power, battery life, etc., are limited. Hence, a schedule is required to optimally allocate network resources so as to maximize some profit or minimize some cost. This thesis focuses on scheduling problems in the wireless sensor networks environment. In particular, we study three scheduling problems in the wireless sensor networks: broadcast scheduling, sensor scheduling for area monitoring, and content distribution scheduling. For each problem the goal is to find efficient scheduling algorithms that have good approximation guarantees and perform well in practice.
De la península ibérica a Italia: concepción y práctica teatral de las primeras comedias castellanas

In my dissertation, De la península Ibérica a Italia: concepción y práctica teatral de las primeras comedias castellanas, I analyze the formation of early modern Spanish comedia, in the context of Italo-Iberian cultural exchanges. My aim is to incorporate the most popular Spanish plays of the first half of the sixteenth century into the larger scenario in which they belong: one that we could name the "formation of the genre of comedy". Works such as Juan del Encina's Eclogues, La Celestina (The Spanish Bawd), and Torres Naharro's Tinellaria and Soldadesca are seen in this light as milestones in a complex thread of contributions leading to the development in the seventeenth century of a Spanish Golden Age "national theater", and specifically in Lope de Vega comedia nueva, as well as to the Italian commedia erudita. Such a reconstruction has long been neglected due to the constitution of the Hispanic and the Italian literary studies, and the asymmetry between the Spanish and the Italian literary traditions, especially regarding the primacy of Italian "comedies" and "authors" in the constitution of a history of "western comedy". The formation of the genre of comedy it is seen in a new light within a textual and bibliographical history, grounded in the relationships among authors, printers, and readers. Cultural and merchant networks established between the Iberian and Italian Peninsulas helped to widespread not only books as commodities, but ideas and forms (genres) contained within them that would appeal to new audiences and readers. In my second chapter, I have reconstructed the possible ways in which these plays could have been represented, in contexts such as Alba de Tormes and Rome, by means of the analysis of internal text evidence (prompts, or configuration of the different scenes) and the extant records, both about its actual performances, and other contemporary spectacles. In order to make sense of the scarce available data, I have delved into architectural treatises (Vitruvio, Alberti, Peruzzi, Serlio), woodcuts, and extant Roman documents on contemporary theatrical performances. As a result of this reconstruction, Encina's latest plays, as well as Naharro's Soldadesca and Tinellaria, appear as deeply rooted in the avant-garde conception of the urban Roman scene, they share both techniques, and scene conceptions with avant-garde Italian authors. In my third chapter, I studied the function that comedies, such as Naharro's Tinellaria and Soldadesca, had at the time, insisting on the religious and political denunciations contained in them, as well as in their relationship with some discourses originating in the Lateran council. As a result of that, I have been able to delimit the circles, critical with the papacy of Julius II, in which these ideas originated, together with the political interests of those that voiced them.
A Critical and Cultural Poetics of the End: Self, Space, and Volatility in Los Angeles
Year of Dissertation:
A Critical and Cultural Poetics of the End: Self, Space, and Volatility in Los Angeles delineates the correspondences between Los Angeles spaces--exterior, topographical, architectural, and imaginary--and aspects of the self--interiority, identity, experience, and desire--in fictional and non-fictional depictions of Los Angeles. Through close readings of key Los Angeles novels, essays, and films, this project emphasizes how the narrative "I" traverses urban space, focusing on the dissolution of boundaries between self and place. Los Angeles' sprawling, decentralized layout and rapidly-shifting landscape have a profound influence on narrative identity, generating a volatile and disquieting sense of self; this project also explores how the city's unique spatial orientation contributes to a literature and cinema of disillusionment exclusive to Los Angeles.
MAG does not Require NgR1, PirB or Sialic Acid Binding to Inhibit Neurite Outgrowth
Year of Dissertation:
The Role of Gangliosides, NgR1, NgR2 and PirB Receptors in MAG Inhibition of Neurite Outgrowth by Najat Al-bashir Thesis Advisor: Dr. Marie T. Filbin Following injury, axons in the central nervous system (CNS) do not spontaneously regenerate, and this is due to several factors, one of which is the presence of myelin- associated inhibitors. There are three major myelin-associated inhibitors that have been identified, Nogo-66, myelin associated glycoprotein (MAG), and Oligodendrocyte myelin glycoprotein (OMgp). MAG is a member of immunoglobulin (IgG) super-family and contains 5 Ig-like domains in its extracellular domain. Like Nogo-66 and OMgp, MAG binds to a receptor complex consisting of NgR1- p75NTR-Lingo-1 to inhibit neurite outgrowth. MAG is also a sialic acid binding protein and specifically binds to gangliosides GT1b and GD1a. Recently, NgR2 was also shown to be a sialic acid- dependent binding receptor for MAG. Recently, paired immunoglobulin B (PirB) was also identified as a novel receptor for MAG, Nogo-66 and OMgp. Previously, we showed that the sialic acid binding activity of MAG is not necessary for its inhibitory effects. We mapped the sialic acid binding site on MAG to Arg 118 in the first Ig-domain. When this site is mutated, sialic acid binding is lost but MAG, when expressed by CHO cells, still retains its ability to inhibit neurite outgrowth. Also, we showed that a soluble form of MAG consisting of the MAG extracellular domain fused to the Fc portion of human IgG (MAG-Fc), and a truncated soluble form of MAG consisting iii only of the first three Ig-like domains (MAG (d1-3)-Fc), both bind to neurons in a sialic acid-dependent manner; however, only MAG-Fc inhibits neurite outgrowth. In addition, MAG mutated at Arg118 (MAG (R118A)-Fc), does not bind to neurons and could not inhibit neurite outgrowth. Recently, we mapped the inhibition site on MAG to Ig-domain 5, which is distinct from the sialic acid binding site. Others have reported that gangliosides are functional binding partners for MAG and are necessary for inhibition by MAG when expressed in immobilized membranes. They reported that neurons from mice deficient in the B1, 4-N-actylgalactosaminyltransferase (GalNAcT) gene, which lack all complex gangliosides including GT1b and GD1a, are not inhibited by MAG in immobilized membrane. Others have also shown that clustering gangliosides with antibodies in the absence of MAG is sufficient to inhibit neurite outgrowth via a mechanism engaging p75 NTR receptor. Here we show that clustering MAG (d1-3)-Fc can inhibit neurite outgrowth in neurons from wild type mice but not from GalNAcT deficient mice. We also show that MAG can inhibit neurite outgrowth independent of NgR1, PirB, and sialic acid binding. We show that neurons from GalNAcT deficient mice are inhibited by MAG as effectively as neurons from wild type mice. Also, we show that neurons from NgR1 deficient mice are inhibited by full length MAG and mutated MAG (MAG R118A) that cannot bind sialic acid residues. In addition, in the presence of PirB antibodies, both MAG- and mutated MAG (R118A)-expressing CHO were able to inhibit neurite outgrowth of neurons from NgR1 deficient mice and wild type mice. Taking all these results together, MAG interacts with another as yet unknown receptor(s), in addition to NgR's, PirB and sialic acid to inhibit neurite outgrowth.
Nanoacoustic Effects in Type-II Superconductors and Decoherence of Two-state Systems
Year of Dissertation:
In this thesis we focus on two areas of research: nanoacoustic effects in superconductors, and decoherence of two-state systems due to radiation of acoustic phonons. In the first part of this thesis we propose two new nanoacoustic effects: induction of voltage by mechanical stress, and nucleation of a superconducting vortex by an acoustic standing wave. Both of these effects take place in type-II superconductors. In the second part we study relaxation processes via acoustic phonons of a particle in a double-well potential and of a flux qubit. Part 1: Mechanical stress causes motion of dislocations in solids. In a type-II superconductor a moving dislocation generates a pattern of current that exerts a force on the surrounding vortex lattice capable of depinning it. We show that the concentration and the speed of dislocations needed to produce depinning currents are within practical range. When external magnetic field and transport current are present, this effect generates voltage across the superconductor. In this manner, a type-II superconductor can serve as an electrical sensor of the mechanical stress. Nucleation of vortices in a superconductor below the first critical field can be assisted by transverse sound in the GHz frequency range. We work out from energy considerations that, in the presence of a sound wave, vortices enter and exit the superconductor at the frequency of the sound. The computed threshold parameters of the sound are shown to be within experimental reach. Part 2: We propose a method of computing phonon-induced relaxation of two-state systems that is based on symmetry arguments. This allows one to express the rates in terms of independently measurable parameters. For translationally and rotationally invariant systems the conservation of linear and angular momenta must be taken into account when formulating the interaction Hamiltonian. For a particle (e.g., electron or proton) in a rigid double-well potential embedded in a solid the rate is proportional to the seventh power of temperature. For a flux qubit the two-phonon relaxation is important only if the size of the qubit is much smaller than the phonon wavelength. Due to symmetry the two-phonon rate of both systems is proportional to the square of the bias. This allows for additional control of the relaxation rate.
Images of Chopin in the New World: Performances of Chopin's Music in New York City, 1839-1876
Year of Dissertation:
This dissertation examines the reception history of the music of Fryderyk Chopin (1810-1849) in the city of New York from the first documented performance of his works, in 1839, until 1876, the year of the historic American tour of Hans von Bülow (1830-1894). The dynamics of those responses correspond with the growth of New York, which, during that time, experienced a dramatic transformation from a provincial city into a vibrant cultural metropolis. In addition, I aim to explore the evolution of musical aesthetics and taste within a larger scope that includes social, political, and cultural issues. That evolution is illustrated by the ways the music of Chopin was performed, disseminated, and criticized demonstrating the presence of points of intersection with other important artistic centers in Europe. My broader goal is to contribute to a better understanding of the dynamics of the musical life of the city in the thirty-seven years covered in this study. A meticulous work of documentation of hundreds of performances provides a valuable tool for scholars who wish to keep exploring that fascinating period in New York history, and the circumstances that paved the way for the future conditions of the musical life in the city and in the nation.
