description: Using first principle calculations we examine properties of (Cd,V)Te, (Cd,Cr)Te, (Hg,V)Te, and (Hg,Cr)Te relevant to the quantum anomalous Hall effect (QAHE), such as the position of V- and Cr- derived energy levels and the exchange interactions between magnetic ions. We consider CdTe and HgTe, containing 12.5% of cation-substitutional V or Cr ions in comparison to the well-known case of (Cd,Mn)Te and (Hg,Mn)Te, and examine their suitability for the fabrication of ferromagnetic barriers or ferromagnetic topological quantum wells, respectively. To account for the strong correlation of transition metal d electrons we employ hybrid functionals with different mixing parameters aHSE focusing on aHSE = 0.32, which better reproduces the experimental band gaps in HgTe, CdTe, Hg0.875Mn0.125Te, and Cd0.875Mn0.125Te. We find that Cr, like Mn, acts as an isoelectronic dopant but V can be an in-gap donor in CdTe and a resonant donor in HgTe, similar to the case of Fe in HgSe. From the magnetic point of view, Cr-doping results in a ferromagnetic phase within the general gradient approximation (GGA) but interactions become antiferromagnetic within hybrid functionals. However, (Hg,V)Te is a ferromagnet within both exchange-correlation functionals in a stark contrast to (Hg,Mn)Te for which robust antiferromagnetic coupling is found theoretically and experimentally. Furthermore, we establish that the Jahn-Teller effect is relevant only in the case of Cr-doping. Considering lower defect concentrations in HgTe-based quantum wells compared to (Bi,Sb)3Te2 layers, our results imply that HgTe quantum wells or (Cd,Hg)Te barriers containing either V or Cr show advantages over (Bi,Sb,Cr,V)3Te2-based QAHE systems but whether (i) ferromagnetic coupling will dominate in the Cr case and (ii) V will not introduce too many electrons to the quantum well is to be checked experimentally

From the Campus to the Underground: The Formation of the Weathermen
Creators: Imperatore, Paul

description: The Weather Underground Organization reversed Students for a Democratic Society's traditional strategy of non-violence at the moment when SDS was at the height of its influence. Up to this point, Weather veterans and sympathetic historians have controlled the historical discourse. Even negative accounts ascribe undue influence to the group, which never involved more than a few hundred people. The Columbia University protests of 1968 were an indispensable step in the eventual triumph of the Weatherman faction. The "Action Faction" had taken power in Columbia SDS and its direct confrontation approach would influence Weatherman after the successful Columbia building occupation. Many of the Columbia leaders, like Mark Rudd, used their celebrity after Columbia to push the "Action Faction" mentality onto SDS at the national level and other Columbia SDS members would go on to join the Weatherman cadre. Later in 1968, the violence at the Democratic National Convention was an important moment for "the Jesse James Gang" of Ann Arbor SDS. The Convention showed that electoral politics were bankrupt. Moreover, because of the extensive media coverage of the protest, those who would form Weatherman adopted "Yippie" style theatrics when protesting because they were guaranteed to get media coverage. After the Weatherman Faction emerged and ousted Progressive Labor from SDS in 1969, the Weathermen began to pursue revolution in solidarity with the third world but in total isolation from the American public. Their sporadic bombings were driven by the false assumption that a worldwide revolution was occurring at the end of the 1960s, but the

description: The subgroups of GL(n,R) that act irreducibly on R^n and that can occur as the holonomy of a torsion-free affine connection on an n-manifold are classified, thus completing the work on this subject begun by M. Berger in the 1950s. The methods employed include representation theory, the theory of hermitian symmetric spaces, twistor theory, and Poisson geometry. The latter theory is especially important for the construction and classification of those torsion-free connections whose holonomy falls into one of the so-called `exotic' cases, i.e., those that were not included in Berger's original lists. Some remarks involving an interpretation of some of the examples in terms of supersymmetric constructions are also included.

description: Language contact, bilingualism and contact-induced language change have created controversial issues among linguists as more and more people of different languages and cultures around the world come into contact. There have been studies of the phenomena of language change including code switching, code mixing, interference, transference, and convergence in different language dyads (Clyne, 2003), especially in multi-lingual societies like Australia, the United States of America and Canada. However, there is insufficient research into the Vietnamese language used in Australia and its changes in comparison with Vietnamese used in Vietnam. This empirical study, therefore, investigates the patterns of pragmatic transference in spoken Vietnamese used by the second generation speakers in Australia who are English-Vietnamese bilinguals. The basic hypothesis of this thesis is that the formulae of pragmatic speech acts in spoken Vietnamese used by the second generation and their lack of knowledge or incorrect usage of Vietnamese idioms and proverbsshow a shift from indirectness to directness in the pragmatic performance of the language. Specifically, the study focuses on the speech act of refusal and the usage of Vietnamese idioms and proverbs. The study documents such pragmatic transference and explores the causes of these changes. The findings will help to fill the gap in the study of language change in linguistics as a whole, and particularly the study of the Vietnamese of the English-Vietnamese bilinguals, and the English-Vietnamese dyad in terms of linguistic and pragmatic elements.The findings have implications for language maintenance among the Vietnamese diaspora community in Australia, for the study of language change in heritage languages, and for understanding trends in the multicultural and multilingual society of Australia.

description: We study a variant of the cyclic Lotka-Volterra model with three-agent interactions. Inspired by a multiplayer variation of the Rock-Paper-Scissors game, the model describes an ideal ecosystem in which cyclic competition among three species develops through cooperative predation. Its rate equations in a well-mixed environment display a degenerate Hopf bifurcation, occurring as reactions involving two predators plus one prey have the same rate as reactions involving two preys plus one predator. We estimate the magnitude of the stochastic noise at the bifurcation point, where finite size effects turn neutrally stable orbits into erratically diverging trajectories. In particular, we compare analytic predictions for the extinction probability, derived in the Fokker-Planck approximation, with numerical simulations based on the Gillespie stochastic algorithm. We then extend the analysis of the phase portrait to heterogeneous rates. In a well-mixed environment, we observe a continuum of degenerate Hopf bifurcations, generalizing the above one. Neutral stability ensues from a complex equilibrium between different reactions. Remarkably, on a two-dimensional lattice, all bifurcations disappear as a consequence of the spatial locality of the interactions. In the second part of the paper, we investigate the effects of mobility in a lattice metapopulation model with patches hosting several agents. We find that strategies propagate along the arms of rotating spirals, as they usually do in models of cyclic dominance. We observe propagation instabilities in the regime of large wavelengths. We also examine three-agent interactions inducing nonlinear diffusion.

title: Understanding Democratic Governance: an inductive analysis of collective co-production in the NHS in England
Creators: name: Kerridge, Thomas Alexander
Publisher: name: Goldsmiths, University of London
Year: 2020

description: This thesis explores the role of collective co-production in facilitating democratic governance in the National Health Service (NHS) in England. Democratic governance offers citizens a role in constructing their communities and institutions. It is a model of governance that is contingent on equality of decision-making between different citizens. However, in the NHS this form of administration has been atypical. Over the past 30 years NHS governance has been based on neo-liberal ethics and latterly institutionalised networks. These models have been imposed through compliance processes that strengthen managerialism and reduce the capacity of the service user. Recently, a number of contemporary governance scholars have critiqued the notion that governance is simply imposed on institutions. Decentred theorists argue that organisations are inherently complex and cannot be understood through ideal models. Instead, they propose that governance is produced through the actions and beliefs of those who operate within institutions. Crucially for this thesis, this approach means that democratic governance can be generated by staff members, patients and other stakeholder communities. In this thesis I study one route through which individuals organise and participate in democratic governance in the NHS. This is ‘collective co-production’: a form of decision-making that enables communities to work together and produce outcomes. To do this I have created an inductive framework that examines how the implementation of collective co-production is influenced by exogenous, institutional and departmental traditions; and which studies how actors participate within collective co-production and engage in equal decision-making.

description: All Lie symmetries of the Burgers equation driven by an external random force are found. Besides the generalized Galilean transformations, this equation is also invariant under the time reparametrizations. It is shown that the Gaussian distribution of a pumping force is not invariant under the symmetries and breaks them down leading to the nontrivial vacuum (instanton). Integration over the volume of the symmetry groups provides the description of fluctuations around the instanton and leads to an exactly solvable quantum mechanical problem.

description: We report on experimental investigation of nonperturbative high harmonic generation (HHG) in monolayer MoS2 in the ultraviolet spectral region driven by mid-infrared light. We study how the HHG is influenced by pre-excitation of the monolayer using resonant and near-resonant pulses in a pump-probe-like scheme. The resonant light creates high density exciton population. Due to ultrafast dephasing caused by electron-electron scattering, the HHG is suppressed in the presence of pre-excited carriers. In the case of near-resonant excitation with photon energy below the exciton transition, the dynamics of the observed suppression of the HHG yield contains a fast component which is a consequence of momentum scattering at carriers, which are excited by two-photon transition when the two pulses temporally overlap in the sample. This interpretation is supported by comparison of the experimental data with theoretical calculations of two-photon absorption spectrum of MoS2 monolayer. This work demonstrates a possibility to control HHG in lowdimensional materials on ultrashort timescales by combining the driving strong-field pulse with a weak near-resonant light.

description: We provide an account of the construction of the moduli stack of elliptic curves as an analytic orbifold. While intimately linked to Thurston's point of view on the subject (discrete groups acting properly and effectively on differentiable manifolds), the construction of the modular orbi-curve and its universal family of elliptic curves ends up requiring a bit more technology, in order to allow for non-effective actions. The paper is entirely expository and makes no claims to originality: its main goal is to be self-contained enough in order to be useful to young researchers who are entering the field and are interested in the interactions between differential and algebraic geometry.

We do not assume any regularity about the constraints; so the constraints need not be $C^1$ or strictly convex. We also show that the optimal regularity holds up to the boundary. Our approach is to show that these elliptic equations with gradient constraints are related to some fully nonlinear double obstacle problems. Then we prove the optimal $W^{2, \infty }$ regularity for the double obstacle problems. In this process, we also employ the monotonicity property for the second derivative of obstacles, which we have obtained in a previous work.

description: This thesis describes research on methods for Ubiquitous/Pervasive Computing to better suit users in an Intelligent Environment. The approach is to create and equip a computing environment, such as our Active Office, with technologies that can identify user needs and meet these need in a timely, efficient and unobtrusive manner.¶ The critical issues in the Intelligent Environment are how to enable transparent, distributed computing to allow continued operation across changing circumstances and how to exploit the changing environment so that it is aware of the context of user location, the collection of nearby people and objects, accessible devices and changes to those objects over time.¶ Since the Intelligent Environment is an environment with rapid and rich computing processing, the distributed context processing architecture (DiCPA) was developed to manage and respond to rapidly changing aggregation of sensor data. This architecture is a scalable distributed context processing architecture that provides: 1. continued operation across changing circumstances for users, 2. the collection of nearby people and objects, 3. accessible devices and 4. the changes to those objects over time in the environment. The DiCPA approach focuses on how the Intelligent Environment provides context information for user location, user mobility and the user activity model. Users are assumed mobile within the Intelligent Environment and can rapidly change their access to relevant information and the availability of communications and computational resources.¶ Context-Aware Computing is a new approach in software engineering for Intelligent Environment. ...

description: Integrals of characteristic classes of tautological sheaves on the Hilbert scheme of points on a surface frequently arise in enumerative problems. We use the K-theoretic Donaldson-Thomas theory of certain toric Calabi-Yau threefolds to study K-theoretic variants of such expressions. We study limits of the K-theoretic Donaldson-Thomas partition function of a toric Calabi-Yau threefold under certain one-parameter subgroups called slopes, and formulate a condition under which two such limits coincide. We then explicitly compute the limits of components of the partition function under so-called preferred slopes, obtaining explicit combinatorial expressions related to the refined topological vertex of Iqbal, Kosçaz and Vafa. Applying these results to specific Calabi-Yau threefolds, we deduce dualities satisfied by a generating function built from tautological bundles on the Hilbert scheme of points on $\mathbb{C}^2$. We then use this duality to study holomorphic Euler characteristics of exterior and symmetric powers of tautological bundles on the Hilbert scheme of points on a general surface.

description: The dissertation follows the trajectory of one of the commodities of the transpacific trade, Chinese porcelain, from the city of Jingdezhen where it was produced, to Manila where it was sold to Spanish merchants, on to Mexico, where it was adopted by the colonial society. The study ends in the city of Puebla where potters drew inspiration from Chinese porcelain for the invention of a new ceramic style known as loza poblana. The methodology of following the trajectory of Chinese porcelains through various sites reveals a new kind of history, one where the tactile aspects of the circulation of goods become salient. The places, contexts, and transactions that the commodities passed through are more prominent--the trade is no longer an abstract exchange between different parties or an endeavor driven purely by imperial greed. Instead it emerges as a process that developed from an interaction between global material forces and local histories and contingencies. Such a tactile history also provides details about the movement and transfer of aesthetics in the early modern period, as seen in the case of the design of the Chinese guan, a jar form, that was adapted to make the Mexican chocolatero.
From the Corners of the Russian Novel: Minor Characters in Gogol, Goncharov, Tolstoy, and Dostoevsky
Creators: Matzner-Gore, Greta Nicole
Publisher: name: Columbia University
Year: 2014
Subjects: Slavic literature

description: This dissertation examines a famous formal peculiarity of nineteenth-century Russian novels: the scores upon scores of characters they embrace. Drawing on terminology developed by Alex Woloch--"character space" and "character system"--I ask how Russian writers use their huge, unwieldy systems of characters to create meaning.
      In each of the four central chapters I analyze a different "overcrowded" nineteenth-century Russian novel: Gogol's Dead Souls, Part I (1842), Goncharov's Oblomov (1859), Tolstoy's Anna Karenina (1875-77), and Dostoevsky's The Brothers Karamazov (1879-80). I address questions such as: what artistic purpose do the many superfluous-seeming minor characters in Gogol's, Goncharov's, Tolstoy's, and Dostoevsky's works serve? What effect does their presence have on the structure of the novels themselves? Why was Dostoevsky so worried by the criticism, which he received throughout the 1870s, that he was "overpopulating" his novels? And how did Dostoevsky's own compositional dilemmas inform both the architectonics and the thematics of The Brothers Karamazov?

      As I argue, there is an increasingly strong sense in nineteenth-century Russian letters that literary characters not only resemble human beings, but even demand of us the same sort of moral obligations that people do. The perceived personhood of literary characters gives particular significance to the narrative decisions realist Russian writers make (such as how to characterize the major vs. minor figures in a novel, and how much or what kind of narrative attention to grant to each), and Gogol, Goncharov, Tolstoy, and Dostoevsky take full artistic advantage of it. They use the enormous number of characters who appear on the pages of their novels in order to pose, through the narrative structure of their works, many of the most important moral, social, and political questions that preoccupy them: What, in essence, is a human being? Are we capable of recognizing (or even simply acknowledging) the psychological complexity of the many, many people who surround us? Can we establish universal brotherhood on earth, a harmonious, unified society that truly includes everyone, even the most disruptive and destructive ones?
From the End to the Middle: Regulation of Telomere Length and Kinetochore Assembly by the RNR Inhibitor SML1
Creators: Gupta, Amitabha
Publisher: name: Columbia University
Year: 2012
Subjects: Molecular biology

description: Accurate DNA replication is essential for proper cellular growth and requires an adequate and balanced supply of dNTPs. In Saccharomyces cerevisiae, de novo dNTP synthesis through nucleotide reduction by the Ribonucleotide reductase (RNR) enzyme is the sole method of production. Hence, RNR activitity is highly regulated via allosteric control, transcriptional control, differential localization of subunits, and direct inhibition of the large subunit, Rnr1, by Sml1. Loss of RNR regulation results in increased mutation due to an imbalance or an absolute change in the dNTP levels in cells. In this study, I describe how mutants in dNTP regulation, including sml1∆, play a role in telomere length homeostasis. Reduction in total dNTP concentration results in a modest decrease in telomere length, while altering the ratios between the four dNTPs has a much more pronounced effect. The altered telomere lengths correlate with the relative amount of dGTP and are dependent on telomerase. At reduced levels of relative dGTP, telomerase repeatedly stalls and dissociates from telomeres, thereby leading to shorter telomeres. Conversely, with elevated relative dGTP levels, telomerase is able to processively add nucleotides and even shows low levels of repeat addition processivity. The correlation between telomerase activity and dGTP is conserved in human telomerase, which shows increased repeat addition processivity at increased dGTP concentrations. Thus, telomere length homeostasis is also sensitive to dNTP regulation in the cell via a conserved dependence on dGTP. RNR regulation is, however, relaxed in the cell following DNA damage to allow for an increase in dNTP levels to repair the damage. In response to various forms of damage, Rad53 and Dun1 are activated and then phosphorylate numerous downstream targets, including the Rnr1 inhibitor Sml1. In this study, it was shown that the phosphorylation of Sml1 triggers its ubiquitylation by the Rad6-Ubr2-Mub1 ubiquitin ligase complex and subsequent degradation by the 26S proteasome. Furthermore, I was able to identify novel genes involved in the degradation of Sml1. Of the genes identified, many are involved in the spindle assembly checkpoint (SAC), cohesin establishment, and kinetochore integrity. The loss of SML1 in mutants of these genes resulted in synthetic growth defects that were not due to the loss of dNTP regulation, indicating a second dNTP-independent function for Sml1. Analysis of the double mutants revealed elevated chromosome loss and aberrant spindle dynamics, pointing to a role for Sml1 in the spindle/kinetochore. Through analysis of kinetochore assembly kinetics, Sml1 was found to be the functional human Mis18α ortholog involved in timely establishment of the kinetochore. Thus, Sml1 has a novel structural function at the kinetochore in addition to its role in dNTP regulation.

description: An experimental study of phase transitions of long-chain n-alkanes induced by the effect of interfaces is described. ¶ The phase behaviour of long-chain n-alkanes (carbon number 14, 16, 17, 18) adsorbed at isolated mica surfaces and confined between two mica surfaces has been studied in the vicinity of and down to several degrees below the bulk melting points, Tm. Using the Surface Force Apparatus we have measured the thickness of alkane films adsorbed from vapour (0.97 [equal to or greater-than] p/p[subscript o] [equal to or greater-than] 0.997), studied capillary condensation transition, subsequent growth of capillary condensates between two surfaces, and phase transitions in both the adsorbed films and the condensates. By measuring the growth rate of the capillary condensates we have identified a transition in the lateral mobility of molecules in the adsorbed films on isolated mica surfaces. This transition to greater mobility occurs slightly above Tm for n-hexadecane, n-heptadecane and n-octadecane but several degrees below Tm for n-tetradecane, and is accompanied by a change in wetting behaviour and a measurable decrease in adsorbed film thickness for n-heptadecane and n-octadecane. Capillary condensates that form below Tm remain liquid, but may freeze if the degree of confinement is reduced by separation of the mica surfaces. An increase in the area of the liquid-vapour interface relative to that of the liquid-mica interface facilitates freezing in the case of the long-chain alkanes, which show surface freezing at the liquid-vapour interface. ¶ Although thermodynamic properties of the surface freezing transition have been rather well documented, the kinetics involved in formation of such ordered monolayers has so far received very little attention. We studied the surface tension of n-octadecane as a function of temperature in the vicinity of Tm, using the static Wilhelmy plate and the dynamic maximum bubble pressure methods. The two methods give different results on cooling paths, where nucleation of the surface ordered phase is involved, but agree on heating paths, where both methods measure properties of the equilibrium surface phase. On cooling paths, the surface of bubbles may supercool below the equilibrium surface freezing temperature. The onset of surface freezing is marked by a sharp drop in the surface tension. The transition is accompanied by an increased stability of the films resulting in longer bubble lifetimes at the liquid surface, which suggests that the mechanical properties of the surfaces change from liquid-like to solid-like. Our results suggest occurrence of supercooling of the monolayer itself.

description: Mercury has been extracted in Queretaro, Mexico since the 1960s. The mining wastes were open-air disposal and these mercury wastes have polluted the zone. The aim of this research was to evaluate mercury's fate in lab scale terrestrial reactors considering the following mercury species: soluble, interchangeable, strongly bound, organic, and residual ones. Soils were sampled in two former mines of Pinal de Amoles, Queretaro, Mexico (N 20° 58′ to 21° 21′ and West 99° 26′ to 99° 43′) with initial mercury concentrations were 424 ± 29 and 433 ± 12 mg kg−1 for “La Lorena” and “San Jose” former mines, respectively. Two vegetal species Polypogon monspeliensis and Cyperus odoratus were used and 20 reactors were constructed for the lab process. Total mercury was removed to 49–79% from both soils. Mercury elemental, exchangeable, and organic species had the most removal or exchange in the process. Metal uptake, by the plants, was of 5–6% for P. monspeliensis and 5–15% for C. odoratus. Also, mercury fate was estimated to the atmosphere to be 3.3–4.5 mg m−2 h−1 for both soils.

description: The eosinophil is a leukocyte whose intracellular mediators are considered to play a central role in the pathogenesis of allergic diseases, including allergic asthma, allergic rhinitis and atopic dermatitis, and which is also involved in immunological responses to parasites. Eosinophil differentiation and maturation from bone marrow progenitors is regulated by interleukin-5 (IL-5), which may be secreted by T helper 2 (Th2) T lymphocytes, and is consistently upregulated in allergic conditions. Eotaxin is a potent chemoattractant for circulating and tissue eosinophils, and the production of this chemokine promotes eosinophil infiltration and accumulation within sites of allergic inflammation.¶ ...¶ In conclusion, eosinophils residing in the allergic lung have the capacity to interact with activated T cells, both within this tissue and the draining lymph nodes. Despite their relative inefficiency as antigen presenting cells (Mawhorter et al., 1994), eosinophils may participate en masse in the serial triggering of activated TCRs, and provide appropriate costimulatory signals that modulate T lymphocyte function. Through the elaboration of Th2 cytokines and stimulation of T cell proliferation, antigen presenting eosinophils may transiently prolong or exacerbate the symptoms of allergic diseases. Alternatively, eosinophils presenting relevant antigens may inhibit T cell activity via degranulation, and such activity has recently been observed in a parasite model (Shinkai et al., 2002). Finally, experiments in the OT-II mouse have provided valuable information to suggest that therapies designed to modulate eosinophil numbers in allergic tissues through the secretion of opposing cytokines such as IFN-γ, may be of limited benefit. The results shown here suggest that airways dysfunction remains intact despite significantly reduced pulmonary eosinophilia

description: A strategy for monitoring and analyzing the chemical stability of Xuebijing injection (XBJ) by multi-wavelength chromatographic fingerprints and multivariate classification techniques is presented in this paper. Multi-wavelength chromatographic fingerprints were constructed using chromatographic data obtained at four wavelengths (260, 280, 320 and 400 nm). The raw chromatography data were preprocessed by noise reduction, baseline correction, data normalization, and interval correlation optimized shifting (icoshift). Using this method, fingerprints of 166 samples of XBJ subjected to different forced degradation conditions (irradiation, high temperature and a range of pH values) were properly represented. Forty-one chemical components were identified using the iPeak program. Additionally, the identified peak area profiling of chemical components were used for multivariate classification analysis. Principal component analysis (PCA) and Ward's method were used to classify different XBJ degradation samples. The PCA score plot showed that XBJ degradation samples were clustered into four groups, and the results are confirmed by Ward's method. Ten key chemical markers under different degradation conditions were found and identified by counterpropagation artificial neural networks (CP-ANN), statistical t-tests and UPLC-Q-TOF-MS. The results suggest that the proposed strategy could be successfully applied to the comprehensive analysis of complex chemical systems.
Robustness of 2 x N x M entangled states against qubit loss

description: Entanglement in quantum systems is usually degraded by interaction with the environment. From time to time, some parties of a multipartite entangled system may become decoherent with other parties of the system due to the interference with the environment. In this situation, it is interesting to know how much information the residual system would keep on carrying. In this paper, as a starting point for any entangled system, we investigate the property of the 2 x N x M state with qubit being disentangled, which is characterized by the measurement of robustness.

description: This project describes various aspects of the breeding ecology and behaviour of the brown falcon Falco berigora, a common but poorly study Australian raptor. In particular it examines (a) the main influences on reproductive success; (b) tests predictions of theories proposed to explain the evolution and maintenance of sexual size dimorphism (RSD; females the larger sex) in raptors; and (c) investigates sex allocation patterns in the light of current sex ratio and parental investment theory. The study was conducted between July 1999 and June 2002 approximately 35 km southwest of Melbourne, at the Western Treatment Plant (WTP), Werribee (38°0’S 144°34’E) and surrounds, a total area of approximately 150 km2.¶ ...

description: We derive a gauge theoretic invariant of integral homology 3-spheres which counts gauge orbits of irreducible, perturbed flat SU(3) connections with sign given by spectral flow. To compensate for the dependence of this sum on perturbations, the invariant includes contributions from the reducible, perturbed flat orbits. Our formula for the correction term generalizes that given by Walker in his extension of Casson's SU(2) invariant to rational homology 3-spheres.

From the Pastoral to the Grotesque in Late Russian Realism, 1872-1899
Creators: Kokobobo, Ani

Subjects: Slavic literature

description: This dissertation argues that, during the last three decades of the nineteenth-century, at a time when, influenced by Mikhail Bakunin's philosophies of destruction, Russian revolutionaries called for the annihilation of tsarist Russia, realist novelists turned to the grotesque mode. Whereas works written by Ivan Turgenev, Sergei Aksakov, Ivan Goncharov, and Tolstoy in the 1850s and 1860s had portrayed Russia in positive terms through the lens of an idyllic countryside, three late realist novels, Fyodor Dostoevsky's Demons (1872), Mikhail Saltykov-Shchedrin's The Golovlevs (1875-1881), and Lev Tolstoy's Resurrection (1899), used the grotesque to cast a negative look at that same world. I base my definition of the grotesque on studies by Mikhail Bakhtin (Rabelais and His World) and Wolfgang Kayser (The Grotesque in Art and Literature), which describe the grotesque as an estrangement of the familiar. Kayser argues that the grotesque distorts the world as we know it; Bakhtin supplements this definition by suggesting that grotesque estrangement leads to a degradation of the abstract and spiritual to the level of physicality and the body. Working with these definitions I argue that Dostoevsky, Saltykov-Shchedrin, and Tolstoy used devices associated with earlier realism to develop their aesthetic of the grotesque and to depict Russian reality in a grotesque mode. They did not simply revive the earlier Gogolian grotesque, but created a new grotesque that estranged traditional idealizing modes of depicting life on the Russian country estate. In these late realist novels Russian reality is populated by despiritualized, grotesque beings.  I set the stage for this project through an analysis of the conceptualist Vladimir Sorokin's Roman (1994), in which he simulates the pastoral idyll of the Russian countryside and then deforms and destroys it through grotesque violence. Like the nineteenth-century novelists, Sorokin reacts against the nostalgic impulse that has prevailed in Russian attitudes toward the past.
