Liszt as Prophet: Religion, Politics, and Artists in 1830s Paris
Creators: Haringer, Andrew Lawrence
Publisher: name: Columbia University
Year: 2012
Subjects: Music
History

description: This dissertation is a study of Liszt's formative years in Paris, with a particular focus on three of his mentors: the priest Félicité Lamennais, the poet-statesman Alphonse de Lamartine, and the musician and mystic Chrétien Urhan. Of all the important figures Liszt encountered during this period, Lamennais, Lamartine and Urhan stand apart in their pursuit of a prophetic mission, whether in religion, politics, art, or a combination thereof. I contend that their influence--more than any other--shaped Liszt's fundamental identity as a liberal Catholic artist, dedicated to social and artistic progress driven by faith. I begin with an introductory chapter on important developments in Paris before and during Liszt's time in the city. The instability of the French Revolution resulted in a dynamic society in which new political, religious, and artistic movements could form and interact. Republican values continued to seek a foothold in the oppressive climates of the Restoration and July monarchies. Similarly, the Church--reinstated by Napoleon but still greatly diminished in power--struggled for relevance in an increasingly indifferent society, leading many Catholics to embrace liberal causes. Finally, the emergence of a new generation of Romantic artists dedicated to leading society forward emerged as an unexpected legacy of the Enlightenment. Each of the three central chapters of this dissertation focuses on one of the figures listed above, and on their impact on Liszt's life and music. Lamennais' radical political and religious message encouraged Liszt to express similar views in word and in music. Lamartine's innovative religious poetry prompted Liszt to seek an equivalent in music. Finally, Urhan's seamless merging of sacred and secular music inspired Liszt to adopt a similar approach in his own compositions. In the final chapter, I trace the continued impact of these figures in Liszt's life and work. Ultimately, I argue that the groundwork for Liszt's most celebrated artistic innovations had already been laid in the early 1830s, and that many of his later works are only comprehensible within the framework of the political, religious, and artistic education he received in his youth.

The report deals with Area C, excavated in 2002, and concentrates on the post-AD 43 features and finds, of which the structural highlights are the partial remains of two further buildings, one constructed in timber, the other with flint foundations. These two buildings, together with the two revealed previously, suggest that in this area there was a complicated series of developments pre- and post-palace.

Literature and Education: Recalling Matthew Arnold

Aesthetics

description: In a democracy, every individual is thought to have the potential to achieve what Matthew Arnold considers the supreme characteristic of intellectual freedom, "the intellectual maturity of man himself; the tendency to observe facts with a critical spirit; to search for their law, not to wander among them at random; to judge by the rule of reason, not by the impulse of prejudice or caprice" (The Complete Prose Works of Matthew Arnold, Vol. 1, p. 21). But Arnold finds a critical opposition between man's instinctive efforts to develop "fully and freely" and the economic forces of the industrial culture of modern democracies, consumed with work and wealth accumulation. He maintains that in the aesthetic experience of literature we behold the being we are capable of. First in his poetry, and later in his critical prose, Arnold confronts the malaise of modernity and the spiritual fragmentation at the heart of contemporary literature. The hope for his project for education is that it can free us to find new critical consciousness and recover the moral authority of aesthetic judgment. In this study I try to explicate Arnold's conviction that collapsing the duality of literature and science expands our knowledge of the world and that cultivating humanity through the experience of ideas in literature affirms the integrity of the individual and reconciles his or her relation to nature and the human community. The aim of this work is twofold. First it recasts Arnold's uncertain legacy among philosophers of education in the perspective of philosophy as a way of life. I hope it also invites further inquiry into his synthesis of intellect and imagination in the aesthetic phenomenon and its capacity to critique conditions of existence.

description: Stack Overflow accumulates an enormous amount of software engineering knowledge. However, as time passes, certain knowledge in answers may become obsolete. Such obsolete answers, if not identified or documented clearly, may mislead answer seekers and cause unexpected problems (e.g., using an out-dated security protocol). In this paper, we investigate how the knowledge in answers becomes obsolete and identify the characteristics of such obsolete answers. We find that: 1) More than half of the obsolete answers (58.4%) were probably already obsolete when they were first posted. 2) When an obsolete answer is observed, only a small proportion (20.5%) of such answers are ever updated. 3) Answers to questions in certain tags (e.g., node.js, ajax, android, and objective-c) are more likely to become obsolete. Our findings suggest that Stack Overflow should develop mechanisms to encourage the whole community to maintain answers (to avoid obsolete answers) and answer seekers are encouraged to carefully go through all information (e.g., comments) in answer threads.

Gauge transformations for a driven quantum particle in an infinite square well

description: Quantum mechanics of a particle in an infinite square well under the influence of a time-dependent electric field is reconsidered. In some gauge, the Hamiltonian depends linearly on the momentum operator which is symmetric but not self-adjoint when defined on a finite interval. In spite of this symmetric part, the Hamiltonian operator is shown to be self-adjoint. This follows from a theorem by Kato and Rellich which guarantees the stability of a self-adjoint operator under certain symmetric perturbations. The result, which has been assumed tacitly by other authors, is important in order to establish the equivalence of different Hamiltonian operators related to each other by quantum gauge transformations. Implications for the quantization procedure of a particle in a box are pointed out.

description: We study the problem of computing the probability for the time-of-arrival of a quantum particle at a given spatial position. We consider a solution to this problem based on the spectral decomposition of the particle's (Heisenberg) state into the eigenstates of a suitable operator, which we denote as the ``time-of-arrival'' operator. We discuss the general properties of this operator. We construct the operator explicitly in the simple case of a free nonrelativistic particle, and compare the probabilities it yields with the ones estimated indirectly in terms of the flux of the Schrödinger current. We derive a well defined uncertainty relation between time-of-arrival and energy; this result shows that the well known arguments against the existence of such a relation can be circumvented. Finally, we define a ``time-representation'' of the quantum mechanics of a free particle, in which the time-of-arrival is diagonal. Our results suggest that, contrary to what is commonly assumed, quantum mechanics exhibits a hidden equivalence between independent (time) and dependent (position) variables, analogous to the one revealed by the parametrized formalism in classical mechanics.

subject: Psychic trauma in literature

description: We are living are living in the age of the trigger warning— educational cultures that threaten English teachers’ ability to present psychologically upsetting literature to students who may lack the necessary resilience to tolerate highly charged literary encounters with complex issues, such as rape, violence, racism, or political strife. And yet literature is filled with conflict— artistic representations of the precise traumas that certain members of our student populations may not be able to tolerate. In order to safeguard trauma survivors from potential reactivation of traumatic stress, a handful of educational institutions promote the use of trigger warnings. But are trigger warnings effective, and, if they are, what do they teach English teachers about what happens to individuals who have endured trauma and are therefore susceptible to being triggered? The purpose of this research, which consisted of interviews and an intensive focus group with seven veteran English teachers teaching at seven distinct schools throughout the world, was to offer insights and pedagogical awareness to English teachers, so that they can better anticipate, conceptualize, and decided for themselves how to respond to students who get triggered by emotionally complex literature. In addition to the qualitative research methods used with the seven English teacher participants, this study utilizes the work and thinking of trauma expert Bessel van der Kolk in an attempt to illustrate the neurological impacts of trauma through a comprehensive overview of PET scans of trauma survivors studied in van der Kolk’s lab in Brookline, Massachusetts. Each PET scan presents key features of what can happen to the brains of survivors, and may provide significant clues into what happens among our students when they get psychologically triggered in the classroom. The dissertation concludes with a one-on-one interview with Harvard psychiatrist Bessel van der Kolk, and offers his insights, wisdom, and conceptualizations for this highly complex and nuanced problem.

description: Most of planet formation models that incorporate planetesimal fragmentation consider a catastrophic impact energy threshold for basalts at a constant velocity of 3 km/s during all the process of the formation of the planets. However, as planets grow the relative velocities of the surrounding planetesimals increase from velocities of the order of m/s to a few km/s. In addition, beyond the ice line where giant planets are formed, planetesimals are expected to be composed roughly by 50 percentage of ices. We aim to study the role of planetesimal fragmentation on giant planet formation considering planetesimal catastrophic impact energy threshold as a function of the planetesimal relative velocities and compositions. We improve our model of planetesimal fragmentation incorporating a functional form of the catastrophic impact energy threshold with the planetesimal relative velocities and compositions. We also improve in our model the accretion of small fragments produced by the fragmentation of planetesimals during the collisional cascade considering specific pebble accretion rates. We find that a more accurate and realistic model for the calculation of the catastrophic impact energy threshold tends to slow down the formation of massive cores. Only for reduced grain opacity values at the envelope of the planet, the cross-over mass is achieved before the disk time-scale dissipation. While planetesimal fragmentation favors the quick formation of massive cores of 5-10 Earth masses the cross-over mass could be inhibited by planetesimal fragmentation. However, grain opacity reduction or pollution by the accreted planetesimals together with planetesimal fragmentation could explain the formation of giant planets with low-mass cores.

description: This article examines the transplantation from Cheshire to mid-Sussex of two branches of the Poole family, subsequent to a double marriage alliance with the Pelhams of Lewes. Zealous local activity in the Newcastle interest was rewarded by the Duke with lucrative places in national administration. The profits of office, supplemented by the fruits of judicious marriage, allowed the consolidation by one branch of a small estate in Chailey where model husbandry was practised and the achievment by the other of a leading position in Lewes society. This prosperity was coincident with a disengagement from the Pelham interest.

description: Environmental planning for a mine site under long-term care and maintenance (LTCM) plays a key role in ensuring organized and efficient use of limited resources. The objective is to minimize operating and maintenance costs and future environmental liabilities. Significant environmental aspects must be identified during the planning phase to minimize environmental liabilities and risks associated with major site components. Some of the major aspects considered during the planning phase for LTCM include, risk assessment, environmental audit, chemical and reagent inventory, development of a decommissioning and closure plan, geochemical characterization of waste rock dumps and tailings, review of environmental monitoring data and reclamation programs and permit requirements, mixed chemical and reagent destruction program, government consultation, emergency preparedness and internal and external communication protocols. This paper discusses the environmental management considerations for a mine site that is currently under long-term care and maintenance together with lessons learned during the implementation of the plan.

description: We consider observational constraints on creation of particles induced by hypothetical trans-Planckian effects during the current stage of the Universe expansion. We show that compatibility with the diffuse gamma-ray background measured by the EGRET experiment strongly restricts this creation. In particular, it rules out the possibility to detect signatures of such short distance effects in anisotropies of the cosmic microwave background radiation. On the other hand, a possibility that some part of the ultra-high energy cosmic rays originates from new trans-Planckian physics remains open.

description: We consider the problem of recovering a continuous-time bandlimited signal from the discrete-time signal obtained from sampling it every $T_s$ seconds and reducing the result modulo $Δ$, for some $Δ>0$. For $Δ=\infty$ the celebrated Shannon-Nyquist sampling theorem guarantees that perfect recovery is possible provided that the sampling rate $1/T_s$ exceeds the so-called Nyquist rate. Recent work by Bhandari et al. has shown that for any $Δ>0$ perfect reconstruction is still possible if the sampling rate exceeds the Nyquist rate by a factor of $πe$. In this letter we improve upon this result and show that for finite energy signals, perfect recovery is possible for any $Δ>0$ and any sampling rate above the Nyquist rate. Thus, modulo folding does not degrade the signal, provided that the sampling rate exceeds the Nyquist rate. This claim is proved by establishing a connection between the recovery problem of a discrete-time signal from its modulo reduced version and the problem of predicting the next sample of a discrete-time signal from its past, and leveraging the fact that for a bandlimited signal the prediction error can be made arbitrarily small.

description: "Literature of Landscape: The Enclosure Movement in the Seventeenth-Century English Imagination" examines the writing of England's rural life: the drama, poetry, and epic that depict it, as well as the political pamphlets and husbandry manuals that sought more directly to reshape it. I explore how land, once seen as an immovable legacy tied to particular forms of community stewardship and use, came to be understood as a commodity over which an individual owner should have absolute dominion. I do this by turning to the moral imagination of Renaissance literature, both canonical and little-known. Engaging the rich historical work on the transformation of land use in the sixteenth and seventeenth centuries, I show how literary, agrarian, and political texts helped early moderns adapt to and make sense of the near total transformation of English rural life that accompanied enclosure and its aftermath: the dissolution of the commons, an expanding and increasingly mobile wage labor market, and changes in land stewardship and agricultural practices prompted by new forms of ownership and loss. At a time when there was no fully developed vocabulary in other forms of discourse, I argue that literary narrative became a key analytical tool for imagining the unimaginable, a ballast and a compass for navigating the seismic socio-economic, environmental, and cultural shifts catalyzed by enclosure.
Litigation Risk and the Optimism in Long-horizon Management Forecasts of Bad News and Good News
Creators: Hurwitz, Helen
Publisher: name: Columbia University
Year: 2012
Subjects: Accounting

description: This study investigates the framework of how litigation risk affects management forecasting of bad news and good news differently, resulting in differential optimism in these forecasts. I argue that distinct stock price patterns following these two types of management forecasts expose them to differential litigation risk ex post. While optimistic management forecasts of good news attract lawsuits, truthful rather than optimistic forecasts of bad news are more likely to trigger immediate lawsuits. As a result, managers adjust the optimism in bad and good news forecasts differently to reduce litigation risk. Consistent with my hypotheses, I find that ex ante litigation risk increases the optimism in bad news management forecasts but does not change the optimism in good news management forecasts, and the optimism in bad news management forecasts is higher than that in their good news counterparts.  In addition, I use RegFD as a natural setting to demonstrate how arguably exogenous shocks amplify this effect. It appears that litigation risk in the pre-RegFD period is not sufficient to affect management forecasting behavior, and my findings only exist in the post-RegFD period. Last, I present evidence that is consistent with investors correctly perceiving and responding to the relative bias in bad new and good news management forecasts.

 Culicoides californiensis Wirth and Blanton, 1967: 215 (key; female, male, pupa; fig. female wing, antenna, palpus, eye separation, spermathecae, leg, pupal respiratory trumpet, male genitalia, parameres; California). Wirth et al. 1985: 20 (numerical characters; fig. female wing). Murphree and Mullen 1991: 329 (key; larva; numerical characters; fig. mandible, epipharynx).
 Culicoides (Amossovia) californiensis: Borkent and Grogan 2009: 12 (in Nearctic catalog).
 Diagnosis. (Tables 14, 15) Yellowish coppery-brown; wing pattern distinct; r 2 dark; distal pale spot in r 3 medially constricted and roughly 8-shaped; pale spots straddling at ~0.25 on M 1 and ~0.4 on M 2; CuA 1 and CuA 2 within dark areas except at tip of CuA 1; pore of sensory pit on palpal segment 3>0.5 the diameter of segment; prominent pale bands basal and subapical on all femora and tibiae; ventral apodeme of gonocoxite simple; aedeagus nearly V-shaped, median process broad triangular with lateral caudally directed spines on midsection, tapering to small blunt tip; parameres separate, apices simple, thick bladelike, pointed.
 Distribution. California, Arizona, Utah (Grand County).
 Larval ecology and adult behavior. Culicoides californiensis has been reared from cottonwood treeholes (Wirth and Blanton 1967), and the mandibular and lacinial teeth on the female indicate it feeds on vertebrate blood. Furthermore, though its larval habitat is arboreal, its frequent collection in low-level CO 2 -baited traps (Table 4) suggests it is a mammalophilic, ground-dwelling bird, or generalist feeder.
 Atypical biology. Of thirteen females and seven males that were slide-mounted, one male has an irregularly disseminated granular infuscation through the thorax and abdomen—possibly by an infection (Fig. 291, Table 11); and two have a third ovoid spermatheca, 0.4 as large as the others, instead of a shriveled vestigial third (Table 12).

Cosmological PPN Formalism and Non-Machian Gravitational Theories

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: By turning to a differential formulation, the post-Newtonian description of metric gravitational theories (PPN formalism) has been extended to include cosmological boundary conditions. The dimensionless expansion parameter is the ratio distance $L$ (measured from the center of a selected space region) to Hubble distance $c/H_0$. The aim was to explore the significance and applicability of a Newtonian cosmology and to clarify to some extent its relation to general-relativistic cosmology. It turns out that up to post-Newtonian order two classes of gravitational theories can be distinguished, here called Machian and non-Machian. In a non-Machian theory like General Relativity the dynamics of cosmic objects within a space region $L \ll c/H_0 $ is described by the usual PPN metric set up for the objects, without introducing time-dependent Newtonian potentials at the origin of the PPN coordinate system. Such potentials of obviously cosmological origin seem to be required for the majority of (by our definition) Machian gravitational theories (including, e.g., Brans-Dicke). Conditions for a theory to be Machian or non-Machian are given in terms of algebraic relations for the PPN parameters.

description: Excavation in advance of a housing development revealed traces of Bronze Age and Iron Age settlement and landscape features, exhibiting continuity of layout across the two phases. Boundary ditches defined land divisions, all apparently part of a single system extending at least 350 m along a terrace edge. Clustering close to these boundaries, isolated pits characterised the two northern areas of the site, while the southern area was occupied by structures and a dense concentration of pits of both periods. The only evidence of ritual activity was a tiny secondary deposit of cremation pyre debris in a ditch fill. It is possible that both phases fall into the transition from Bronze Age to Iron Age, in the eighth century BC. Includes an online supplement, and separately authored contributions on

description: The challenge of effectively isolating sulphide bearing waste rock and tailings requires that oxidation of sulphides be prevented and/or the escape of interstitial salt solutions from the tailings mass be prevented. The establishment of a water cover over top of tailings has been demonstrated to effectively reduce the oxidation of sulphides and thereby minimize acid generation and metal leaching. A new approach to the control of sulphide tailings oxidation is being developed by Falconbridge Limited and Lakefield Research Limited. The technique under development involves the establishment of a composite cover of inorganic minerals, of appropriate layer thickness, hydraulic properties and composition over the deposit in such a way that both evaporation and surface run-off are greatly reduced and/or eliminated. The granular cover system is suitable to tailings deposits that have a gentle slope and do not contain large hydraulic discontinuities. The system is also best suited to geographical site locations where precipitation is not a limiting factor. This paper describes the development of the granular cover system from bench scale testwork through to pilot field scale evaluation and summarizes the results from three consecutive years of field monitoring.

description: In the regression setting, given a set of hyper-parameters, a model-estimation procedure constructs a model from training data. The optimal hyper-parameters that minimize generalization error of the model are usually unknown. In practice they are often estimated using split-sample validation. Up to now, there is an open question regarding how the generalization error of the selected model grows with the number of hyper-parameters to be estimated. To answer this question, we establish finite-sample oracle inequalities for selection based on a single training/test split and based on cross-validation. We show that if the model-estimation procedures are smoothly parameterized by the hyper-parameters, the error incurred from tuning hyper-parameters shrinks at nearly a parametric rate. Hence for semi- and non-parametric model-estimation procedures with a fixed number of hyper-parameters, this additional error is negligible. For parametric model-estimation procedures, adding a hyper-parameter is roughly equivalent to adding a parameter to the model itself. In addition, we specialize these ideas for penalized regression problems with multiple penalty parameters. We establish that the fitted models are Lipschitz in the penalty parameters and thus our oracle inequalities apply. This result encourages development of regularization methods with many penalty parameters.

description: Aerial drones are becoming an integral part of application domains including but not limited to, military operations, package delivery, construction, monitoring and search/rescue operations. It is critical to ensure the cyber security of networked aerial drone systems in these applications. Standard cryptographic services can be deployed to provide basic security services; however, they have been shown to be inefficient in terms of energy and time consumption, especially for small aerial drones with resource-limited processors. Therefore, there is a significant need for an efficient cryptographic framework that can meet the requirements of small aerial drones. We propose an improved cryptographic framework for small aerial drones, which offers significant energy efficiency and speed advantages over standard cryptographic techniques. (i) We create (to the best of our knowledge) the first optimized public key infrastructure (PKI) based framework for small aerial drones, which provides energy efficient techniques by harnessing special precomputation methods and optimized elliptic curves. (ii) We also integrate recent light-weight symmetric primitives into our PKI techniques to provide a full-fledged cryptographic framework. (iii) We implemented standard counterparts and our proposed techniques on an actual small aerial drone (Crazyflie 2.0), and provided an in-depth energy analysis. Our experiments showed that our improved cryptographic framework achieves up to 35x lower energy consumption than its standard counterpart.

description: We carry out the stability analysis of the Schwarzschild black hole in Gauss-Bonnet and Chern-Simons-scalar theory. Here, we introduce two quadratic scalar couplings ($ϕ_1^2,ϕ_2^2$) to Gauss-Bonnet and Chern-Simons terms, where the former term is parity-even, while the latter one is parity-odd. The perturbation equation for the scalar $ϕ_1$ is the Klein-Gordon equation with an effective mass, while the perturbation equation for $ϕ_2$ is coupled to the parity-odd metric perturbation, providing a system of two coupled equations. It turns out that the Schwarzschild black hole is unstable against $ϕ_1$ perturbation, leading to scalarized black holes, while the black hole is stable against $ϕ_2$ and metric perturbations, implying no scalarized black holes.

description: Excavations identified eight periods of activity. A flint gravel `hard' for beaching ships was followed by twelfth-century alluvium cover and rubbish dumping. Grey Friars was founded before 1241 on the built-up surface of the floodplain, in damp conditions, and partial rebuilding took place on the south side of the cloisters. Major rebuilding in period four evinced a chalk rubble layer, dumped to raise the ground level. Minor alteration in the fifteenth--sixteenth centuries were followed by Dissolution, demolition of many buildings, the continued use of some until the late seventeenth century, then the demolition of these too and the construction of The Friars (a house). Fifty-five medieval burials were recovered from the church, cloister walk, cloister garth and graveyard, the majority of which were adult males.

On Bohr-Sommerfeld bases

description: This paper combines algebraic and Lagrangian geometry to construct a special basis in every space of conformal blocks, the Bohr-Sommerfeld (BS) basis. We use the method of [D. Borthwick, T. Paul and A. Uribe, Legendrian distributions with applications to the non-vanishing of Poincaré series of large weight, Invent. math, 122 (1995), 359-402, preprint hep-th/9406036], whereby every vector of a BS basis is defined by some half-weighted Legendrian distribution coming from a Bohr-Sommerfeld fibre of a real polarization of the underlying symplectic manifold. The advantage of BS bases (compared to bases of theta functions in [A. Tyurin, Quantization and ``theta functions'', Jussieu preprint 216 (Apr 1999), e-print math.AG/9904046, 32pp.]) is that we can use information from the skillful analysis of the asymptotics of quantum states. This gives that Bohr-Sommerfeld bases are unitary quasi-classically. Thus we can apply these bases to compare the Hitchin connection with the KZ connection defined by the monodromy of the Knizhnik-Zamolodchikov equation in combinatorial theory (see, for example, [T. Kohno, Topological invariants for 3-manifolds using representations of mapping class group I, Topology 31 (1992), 203-230; II, Contemp. math 175} (1994), 193-217]).

Lithium changes the way light resets the brain’s internal clock in a mouse model of bipolar depression

description: Lithium is the drug of choice for treating patients suffering from bipolar disorder (BP), a disorder characterized by mood swings between mania and depression. Though the exact pathway by which lithium acts to counteract the symptoms of BP is unknown, we do know that lithium helps animals entrain to a longer circadian rhythm. Studies have shown that patients with BP tend to have a shorter circadian rhythm than the near 24h period shown by a normal individual and experience difficulty synchronizing to the external light and dark (LD) cues of a 24h day. We hypothesize that because light is such a potent entraining cue, lithium may interact with LD signals on the brain’s internal clock, the suprachiasmatic nucleus (SCN), to enable BP individuals entrain to the 24 hour day. In order to determine the effects of lithium on brain and locomotor behavior, mice were placed in a 28 hour day consisting of 14:14 light:dark cycle. Animals were randomly divided into groups and fed either control chow or lithium supplemented chow. Analysis of wheel running behavior and levels of FOS expression in the SCN showed that animals on a lithium diet exhibited a greater response to the light pulse given in the night and were better able to entrain to the longer 28 hour day. We conclude that lithium acts upon an animal’s endogenous clock, thereby facilitating entrainment to a lengthened external cycle.
