History

description: This thesis deals exclusively with monuments commemorating the Confederacy, Confederate soldiers and war heroes, the antebellum South, slavery, Reconstruction, and Jim Crow that endure in countless public spaces throughout the American South. Postbellum monuments incite local controversy over whether to remove or preserve the monument on its original site. Because there exists an eclectic range of monuments dedicated in memory of a variety of people, places, and events, the term Civil War monument or Confederate monument fails to encapsulate the scope of what these monuments commemorate as well as the wide span of time in which they were built. For the duration, I refer to these monuments as postbellum monuments within the postbellum commemorative landscape in reference to its general years of construction, 1865 to 1940, the period following the Civil War and before the Civil Rights era.

Historians and preservation professionals value these monuments as a historic resource, which serves to illustrate the fight over public memory that ensued following Reconstruction and in conjunction with the institutionalization of Jim Crow. However, not all see these monuments as valuable objects of history. Postbellum monuments convey, to some, a lasting message of white supremacy and romanticize a society built upon a system of slave labor, while others defend the significance of these monuments as contributing to their personal understanding of Southern history, identity, and heritage. The preservation of postbellum monuments in public spaces is dogged at every turn by the history that bore them into being in the first place.

The instinct of caretakers in charge of the preservation of postbellum monuments is to placate the immediate discomforts of concerned citizens without addressing the foundational problems that incited debate in the first place. Such failures are indicative of a flaw in preservation methodology that stresses stakeholder participation in developing preservation management policies in situations where agreement is impossible and compromise ineffective in responding to groups advocating for removal. The idea that preservationists can guide stakeholders beyond their political differences is an absurd fantasy; a statue cannot bring groups together who have such fundamentally conflicting values and beliefs. Preservation professionals have the ability to use the past to create positive changes in American society, but only as political actors who strongly advocate for the educational value of the historic narrative told by postbellum monuments, not as mediators trying to balance hardline stakeholder values.

description: Current industrial development is faced by the global challenge to meet the continuously growing demand for capital and consumer goods in emerging countries while simultaneously ensuring a sustainable industrial growth in the social, environmental and economic dimension. By means of market dynamics of cooperation and competition in global value creation and knowledge networks, innovations geared towards sustainability can be essential drivers for realizing a sustainable development. The targeted development of new sustainable innovations is consequently a key activity in order to move towards sustainable industrial growth. This paper will describe a model for the development of sustainable innovations. The model focuses on idea generation in the early phase of the innovations process, addressing the fuzzy front end of innovation. In this context, specific goals and principles of sustainable development are integrated into a problem-solving approach. This integrated approach is subsequently used as a foundation for the targeted development of sustainable innovations in the frame of a workshop concept.

description: We research the entropy of a black hole in curved space-times by 't Hooft`s approach, so-called the brick wall method. One of these space-time, a asymptotically dS space-time has two physical horizons; one is a black hole horizon and the other is a cosmological horizon. The others have only one horizon, a black hole horizon. Using this model, we calculate all thermodynamic quantities containing the background geometric effect and show that entropy is proportional to area of each boundary. Furthermore, we show that the Cardy-Verlinde formula can be rederived from the physical quantities of the brick wall method and this fact becomes a evidence of the dS/CFT correspondence.

description: As part of a large Hubble Space Telescope investigation aiming at reaching the faintest stars in the Galactic globular cluster NGC 6752, an ACS/WFC field was the subject of deep optical observations reaching magnitudes as faint as V~30. In this field we report the discovery of Bedin I a dwarf spheroidal galaxy too faint and too close to the core of NGC 6752 for detection in earlier surveys. As it is of broad interest to complete the census of galaxies in the local Universe, in this Letter we provide the position of this new object along with preliminary assessments of its main param eters. Assuming the same reddening as for NGC 6752, we estimate a distance modulus of (m-M)_0 = 29.70+/-0.13 from the observed red giant branch, i.e., 8.7 (+0.5 -0.7) Mpc, and size of ~840x340pc, about 1/5 the size of the LMC. A comparison of the observed colour-magnitude diagram with synthetic counterparts that account for the galaxy distance modulus, reddening and photometric errors, suggests the presence of an old (~13Gyr) and metal poor ([Fe/H]~-1.3) population. This object is most likely a relatively isolated satellite dwarf spheroidal galaxy of the nearby great spiral NGC 6744, or potentially the most distant isolated dwarf spheroidal known with a secure distance.

Loop type subcontinua of positive solutions for indefinite concave-convex problems

description: We establish the existence of loop type subcontinua of nonnegative solutions for a class of concave-convex type elliptic equations with indefinite weights, under Dirichlet and Neumann boundary conditions. Our approach depends on local and global bifurcation analysis from the zero solution in a non-regular setting, since the nonlinearities considered are not differentiable at zero, so that the standard bifurcation theory does not apply. To overcome this difficulty, we combine a regularization scheme with a priori bounds, and Whyburn's topological method. Furthermore, via a continuity argument we prove a positivity property for subcontinua of nonnegative solutions. These results are based on a positivity theorem for the associated concave problem proved in [15], and extend previous results established in the powerlike case.

H$_2$O abundances and cloud properties in ten hot giant exoplanets

description: Transmission spectroscopy of exoplanets has the potential to provide precise measurements of atmospheric chemical abundances, in particular of hot Jupiters whose large sizes and high temperatures make them conducive to such observations. To date, several transmission spectra of hot Jupiters have revealed low amplitude features of water vapour compared to expectations from cloud-free atmospheres of solar metallicity. The low spectral amplitudes in such atmospheres could either be due to the presence of aerosols that obscure part of the atmosphere or due to inherently low abundances of H$_2$O in the atmospheres. A recent survey of transmission spectra of ten hot Jupiters used empirical metrics to suggest atmospheres with a range of cloud/haze properties but with no evidence for H$_2$O depletion. Here, we conduct a detailed and homogeneous atmospheric retrieval analysis of the entire sample and report the H$_2$O abundances, cloud properties, terminator temperature profiles, and detection significances of the chemical species. Our present study finds that the majority of hot Jupiters have atmospheres consistent with sub-solar H$_2$O abundances at their day-night terminators. The best constrained abundances range from $\mathrm{log(H_2O)}$ of $-5.04^{+0.46}_{-0.30}$ to $-3.16^{+0.66}_{-0.69}$, which compared to expectations from solar-abundance equilibrium chemistry correspond to $0.018^{+0.035}_{-0.009}\times$ solar to $1.40^{+4.97}_{-1.11}\times$ solar. Besides H$_2$O we report statistical constraints on other chemical species and cloud/haze properties, including cloud/haze coverage fractions which range from $0.18^{+0.26}_{-0.12}$ to $0.76^{+0.13}_{-0.15}$. The retrieved H$_2$O abundances suggest sub-solar oxygen and/or super-solar C/O ratios, and can provide important constraints on the formation and migration pathways of hot giant exoplanets.

description: Drawing upon the regulatory theories of focus, mode, and fit, the three chapters of this dissertation demonstrate that subtle distinctions in framing and word choice can have profound impact for entrepreneurs and their startups. In Chapter 1, a field study and experiment on regulatory focus reveal that investors pose promotion-focused questions in the domain of gains to male entrepreneurs and prevention-focused questions in the domain of losses to female entrepreneurs, helping to explain the sizable gap in their respective funding outcomes. Chapter 2’s archival and experimental studies pertaining to regulatory mode indicate that organizations with mission statements high in locomotion (the mode of urgent action) and low in assessment (the mode of thoughtful consideration) have a greater likelihood and frequency of involvement in Equal Employment Opportunity Commission cases of discrimination. Across an observational and experimental study, Chapter 3 shows entrepreneurs seek regulatory fit in the form of social identity alignment that helps to explain variations in talent selection and retention, with those manifesting the identity of a “builder” (motivated to incrementally improve over time) exhibiting higher tenure rates than those manifesting the identity of a “disrupter” (motivated to break with the status quo). Implications for theory and practice are discussed.

description: A model for 1D traffic flow is developed, which is discrete in space and time. Like the cellular automaton model by Nagel and Schreckenberg [J. Phys. I France 2, 2221 (1992)], it is simple, fast, and can describe stop-and-go traffic. Due to its relation to the optimal velocity model by Bando et al. [Phys. Rev. E 51, 1035 (1995)], its instability mechanism is of deterministic nature. The model can be easily calibrated to empirical data and displays the experimental features of traffic data recently reported by Kerner and Rehborn [Phys. Rev. E 53, R1297 (1996)].

Bold Impressions: A Comparative Analysis of Artist Prints and Print Collecting at the Imperial War Museum and Australian War Memorial

description: This thesis examines the historical development of the artist print collections of the Imperial War Museum and Australian War Memorial, and analyses the relationship of these collections to their institutions. Printmaking is an artistic medium that has historically been used by artists for social critique, and many high quality works of this type are present in the two collections. I argue that in both museums, when developing the print collections, curators were able to acquire beyond the strict interpretation of the museums’ collecting guidelines. As a result of this, the prints have challenged some of the more conservative underlying messages of the museums. National war museums are ideal for a study of contested histories, particularly those within their own collections, and the IWM and AWM are prominent institutions in this specialist category of museums. My hypothesis is that prints can destabilize the histories that war museums wish to present due to their historical use by artists for a variety of purposes that are somewhat unique to the medium. This is driven by the materiality of the print. This study also analyses how museum structures and internal cultures affected the development of the print collections. In particular, I have tried to answer the questions: What factors influenced the development of the print collections? And how did the professional agendas of curators inform that development? Print collecting flourished at key points in the histories of the institutions, particularly when fine art specialists were in charge of acquisitions. While print collecting broadly reflected the aims of the institutions at different times, on occasion it introduced divergent narratives into the war museums. This thesis is interdisciplinary in the way it uses a history methodology and museum studies framework. The historical research methods employed include archival research and semi-structured interviews with selected former and current museum staff. My research will add to academic and curatorial knowledge about how collections are formed in large national museums, and analyse the role and significance of two collections that have not previously been thoroughly examined. The thesis places the curator as the creator of the collection, not merely as someone who carries out instructions from management, but who negotiates between the institutional forces, social forces and the nature of the objects, to ultimately shape the collection.

description: We apply the long-wavelength approximation to the low energy effective string action in the context of Hamilton-Jacobi theory. The Hamilton-Jacobi equation for the effective string action is explicitly invariant under scale factor duality. We present the leading order, general solution of the Hamilton-Jacobi equation. The Hamilton-Jacobi approach yields a solution consistent with the Lagrange formalism. The momentum constraints take an elegant, simple form. Furthermore this general solution reduces to the quasi-isotropic one, if the evolution of the gravitational field is neglected. Duality transformation for the general solution is written as a coordinate transformation in an abstract field space.

description: We study the time evolution of Solar Flares activity by looking at the statistics of quiescent times $τ_{L}$ between successive bursts. The analysis of 20 years of data reveals a power law distribution with exponent $α\simeq 2.4$ which is an indication of complex dynamics with long correlation times. The observed scaling behavior is in contradiction with the Self-Organized Criticality models of Solar Flares which predict Poisson-like statistics. Chaotic models, including the destabilization of the laminar phases and subsequent restabilization due to nonlinear dynamics, are able to reproduce the power law for the quiescent times. In the case of the more realistic Shell Model of MHD turbulence we are able to reproduce all the observed distributions.

description: We demonstrate inter-valley Bloch oscillation (BO) and Landau-Zener tunneling (LZT) in an optically-induced honeycomb lattice with a refractive index gradient. Unlike previously observed BO in a gapped square lattice, we show non-adiabatic beam dynamics that are highly sensitive to the direction of the index gradient and the choice of the Dirac cones. In particular, a symmetry-preserving potential leads to nearly perfect LZT and coherent BO between the inequivalent valleys, whereas a symmetry-breaking potential generates asymmetric scattering, imperfect LZT, and valley-sensitive generation of vortices mediated by a pseudospin imbalance. This clearly indicates that, near the Dirac points, the transverse gradient does not always act as a simple scalar force as commonly assumed, and the LZT probability is strongly affected by the sublattice symmetry as analyzed from an effective Landau-Zener Hamiltonian. Our results illustrate the anisotropic response of an otherwise isotropic Dirac platform to real-space potentials acting as strong driving fields, which may be useful for manipulation of pseudospin and valley degrees of freedom in graphene-like systems.

We show that the effective action is manifestly invariant under the loop-corrected SUSY transformation, and give the explicit transformation laws. The effective action consists of blocks which are closed under the SUSY, and includes the supersymmetric completion of the couplings to the longitudinal 5-branes proposed by Taylor and Van Raamsdonk as a subset.

description: Due to the combined effect of anisotropic interactions and activity, Janus swimmers are capable to self-assemble in a wide variety of structures, many more than their equilibrium counterpart. This might lead to the development of novel active materials capable of performing tasks without any central control. Their potential application in designing such materials endows trying to understand the fundamental mechanism in which these swimmers self-assemble. In the present work, we study a quasi-two dimensional semi-dilute suspensions of two classes of amphiphilic spherical swimmers whose direction of motion can be tuned: either swimmers propelling in the direction of the hydrophobic patch (WP), or swimmers propelling in the opposite direction (towards the hydrophilic side) (AP). In both systems we have systematically tuned swimmers' hydrophobic strength and signature, and observed that the anisotropic interactions, characterized by the angular attractive potential and its interaction range, in competition with the active stress, pointing towards or against the attractive patch gives rise to a rich aggregation phenomenology.

Annihilation decay rates of P-wave positronium are negligible compared to the rates of radiative electric dipole transitions to the ground state. This circumstance makes such decays experimentally inaccessible. However the situation is different for quarkonium and the experimental and theoretical research of two-photon and two-gluon decays of P-wave quarkonia is a still flourishing field.

description: We present Monte-Carlo simulations of a cosmological population of repeating fast radio burst (FRB) sources whose comoving density follows the cosmic star formation rate history. We assume a power-law model for the intrinsic energy distribution for each repeating FRB source located at a randomly chosen position in the sky and simulate their dispersion measures (DMs) and propagation effects along the chosen lines-of-sight to various telescopes. In one scenario, an exponential distribution for the intrinsic wait times between pulses is chosen, and in a second scenario we model the observed pulse arrival times to follow a Weibull distribution. For both models we determine whether the FRB source would be deemed a repeater based on the telescope sensitivity and time spent on follow-up observations. We are unable to rule out the existence of a single FRB population based on comparisons of our simulations with the longest FRB follow-up observations performed. We however rule out the possibility of FRBs 171020 and 010724 repeating with the same rate statistics as FRB 121102 and also constrain the slope of a power-law fit to the FRB energy distribution to be $-2.0 < γ

description: We report on the detection of a blueshifted Fe K absorption feature in two consecutive XMM-Newton observations of the luminous blue quasar Ton 28, at the 4$σ$ cumulative significance. The rest energy of 9.2 keV implies the presence of an accretion disc wind with bulk outflow velocity of $\sim$0.28$c$, while the kinetic power is most likely a few per cent of the quasar luminosity. Remarkably, Ton 28 had been specifically selected as an optimal target to reveal an ultra-fast X-ray wind based on its total luminosity ($L_{\rm bol} > 10^{46}$ erg s$^{-1}$) and [OIII] $λ$5007Å equivalent width (EW < 6 Å), suggestive of high accretion rate and low inclination, respectively. Other peculiar optical/UV emission-line properties include narrow H$β$, strong FeII and blueshifted CIV. These are key parameters in the Eigenvector 1 formalism, and are frequently found in active galaxies with ongoing accretion disc winds, hinting at a common physical explanation. Provided that the effectiveness of our selection method is confirmed with similar sources, this result could represent the first step towards the characterization of black-hole winds through multiwavelength indicators in the absence of high-quality X-ray spectra.

Our numerical results remind us to deny the opinion that there are no complex phenomena in short-time delay case. Many similarities between foundamental solution and the new type of solutions are found. We demonstrate that the scales of $S_i$ increase with exponential growth via $i$ in the direction of $μ$, while decrease with exponential decays in the direction of $x$ or delay time $t_R$.

description: The Einstein Equivalence Principle (EEP) underpins all metric theories of gravity. One of its key aspects is the local position invariance (LPI) of non-gravitational experiments, which is captured by the gravitational red-shift. The iconic gravitational red-shift experiment places two fermionic systems, used as clocks, in different gravitational potentials and compares them using the electromagnetic field. However, the electromagnetic field itself can be used as a clock, by comparing the phases acquired by two optical pulses propagating through different gravitational potentials. A fundamental point in the implementation of a satellite large-distance optical interferometric experiment is the suppression of the first-order Doppler effect, which dominates the weak gravitational signal necessary to test the EEP. Here, we propose a novel scheme to suppress it, by subtracting the phase-shifts measured in the one-way and in the two-way configuration between a ground station and a satellite. We present a detailed analysis of this technique within the post-Newtonian framework and perform some simulations of its performance using realistic satellite orbits and the state-of-the-art fiber technology at the telecom wavelength of 1550 nm.

Three Essays in Empirical Corporate Finance

description: This dissertation presents three essays in empirical corporate finance. The essays discuss how financial markets affect the real economy. The first essay studies how a change in credit supply affects firms’ decisions to create new products or destroy the existing ones. It provides reduced form causal evidence that a reduction in credit supply reduces product creation substantially. The second essay studies the effect of less product creation on consumer welfare. I find that the effect on consumer welfare is smaller relative to a “naive” interpretation of the reduced form estimate, due to equilibrium responses. The third essay studies how financially constrained firms reduce total investment costs. It provides suggestive evidence that when reducing total investment cost, they do so by lowering the expansion of output capacity and choosing cheaper investment options.
The London Connection: the formation and early years of the Australian Agricultural Company

description: The Australian Agricultural Company was formed in London in 1824 to promote the raising of fine wool in New South Wales. Previous treatments of the Company's formation and early years have focussed principally on developments in New South Wales. In contrast, it is maintained here that the Company's genesis can only be fully understood in the context of the London financial market and imperial investment of the time; the family and business connections of the promoters and directors; and the changing nature of the British wool market. Further, it is argued, that the Company's survival through its first decade owed far more to the Court of Directors in London than ever previously acknowledged. The work is divided into two parts. Part I explores the context in which the Company was formed. Its four chapters cover the Stock Market boom of 1823-4 (which also saw the flotation of the Van Diemen's Land and Canada Companies); an analysis of the British shareholders, particularly the role of John Macarthur the younger (the son of John Macarthur of Parramatta and Camden): a survey of the British wool market; and the development of New South Wales wool to 1824 and its entry into the British market. The first two chapters of Part II sets out the circumstances surrounding the Company's formation in 1824, and the Directors' decision in 1825 to take over the coal mines in New South Wales. The following chapters then examine, chronologically, developments in London and New South Wales which culminated in August 1834, with the decision to pay the Company's first dividend.
Immediate outcomes for tertiary students of dealing with stressful situations : interpersonal conflict or an exam
Creators: name: Taylor, Marie
Publisher: name: The Australian National University
Year: 1994

description: The relationships between coping strategies and both mood outcomes and a measure of the quality of the outcome of problem situations were explored in a study of 115 students enrolled in tertiary education. Subjects completed one of two questionnaires dealing with their experience earlier that day of either an exam or conflict with another person. Different coping strategies were adopted depending on the situation. Hierarchical regression analyses indicated that heightened negative mood was most likely in older students who faced many daily hassles and who used escapeavoidance behaviours to deal with their particular problem situation. Increased positive mood was predicted by greater use of positive reappraisal and distancing strategies. Coping efforts made no difference to judgments about the quality of the outcome of the problem situation. Correlational data indicated that coping strategies showed both generality and specificity in their relationships with different types of outcomes. The use of some coping strategies was related to both worse negative mood and judgments that the problem situation seemed worse, whereas the use of other strategies was related to just one type of outcome.
Quantum fluctuations and phase coherence in superconducting nanowires

description: Quantum behavior of superconducting nanowires may essentially depend on the employed experimental setup. Here we investigate a setup that enables passing equilibrium supercurrent across an arbitrary segment of the wire without restricting fluctuations of its superconducting phase. The low temperature physics of the system is determined by a combined effect of collective sound-like plasma excitations and quantum phase slips. At $T=0$ the wire exhibits two quantum phase transitions, both being controlled by the dimensionless wire impedance $g$. While thicker wires with $g>16$ stay superconducting, in thinnest wires with $g<2$ the supercurrent is totally destroyed by quantum fluctuations. The intermediate phase with $2

A Microscopical Description of Giant Gravitons

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We construct a non-Abelian world volume effective action for a system of multiple M-theory gravitons. This action contains multipole moment couplings to the eleven-dimensional background potentials. We use these couplings to study, from the microscopical point of view, giant graviton configurations where the gravitons expand into an M2-brane, with the topology of a fuzzy 2-sphere, that lives in the spherical part of the AdS_7 x S^4 background or in the AdS part of AdS_4 x S^7. When the number of gravitons is large we find perfect agreement with the Abelian, macroscopical description of giant gravitons given in the literature.

Computing the spectrum of black hole radiation in the presence of high frequency dispersion: an analytical approach

description: We present a method for computing the spectrum of black hole radiation of a scalar field satisfying a wave equation with high frequency dispersion. The method involves a combination of Laplace transform and WKB techniques for finding approximate solutions to ordinary differential equations. The modified wave equation is obtained by adding a higher order derivative term suppressed by powers of a fundamental momentum scale $k_0$ to the ordinary wave equation. Depending on the sign of this new term, high frequency modes propagate either superluminally or subluminally. We show that the resulting spectrum of created particles is thermal at the Hawking temperature, and further that the out-state is a thermal state at the Hawking temperature, to leading order in $k_0$, for either modification.

description: We apply a global and geometrically well-defined formalism for spinor-dilaton-gravity to two-dimensional manifolds. We discuss the general formalism and focus attention on some particular choices of the dilatonic potential. For constant dilatonic potential the model turns out to be completely solvable and the general solution is found. For linear and exponential dilatonic potentials we present the class of exact solutions with a Killing vector.

A Revolutionary Response: The 1926 Marriage Law of the R.S.F.S.R

description: This thesis challenges the conventional (Western) scholarly view that has focused on the Bolsheviks' 1926 Marriage Law as part of a doctrinaire Marxist vision to abolish the bourgeois family. A detailed examination of the debates in 1925 and 1926 in the All-Russian Central Executive Committee, and exchanges in the press and periodicals of the time, show that - the central authorities' Marxist rhetoric notwithstanding - the law was not an assault on the family, but a pragmatic and reformist policy to extend alimony and other protections to women by recognising both de jure and de facto marriages. Moreover, the debates of 1925 and 1926, occurring at the height of the New Economic Policy and at a time when the Bolsheviks had decided that a tactical alliance between the urban proletariat and peasantry was necessary, marked a resurgence of traditionalist and conservative rhetoric about the family's role and women's role in society. This social conservatism was a sign of things to come under Stalin's moral conservatism. The recognition of de facto marriages in the Soviet Union was to be short-lived: the 1944 Family Law abolished it. The thesis also examines the contribution to the debate made by Alexandra Kollontai, a noted Russian feminist author and politician, the first female People's Commissar and the first female Ambassador of the Soviet Union (to Norway). Kollontai used the debate to propose ideas which appear socially progressive viewed through a modern lense but were derided as utopian in the post-revolutionary conditions of the 1920s: a mandatory, income-based levy to fund support for single mothers and children, and the conclusion of marital contracts recognising the economic value of women's work in the household.

description: The author has previously extended the theory of regular and irregular primes to the setting of arbitrary totally real number fields. It has been conjectured that the Bernoulli numbers, or alternatively the values of the Riemann zeta function at odd negative integers, are evenly distributed modulo p for every p. This is the basis of a well-known heuristic given by Siegel for estimating the frequency of irregular primes. So far, analyses have shown that if Q(\sqrt{D}) is a real quadratic field, then the values of the zeta function ζ_{D}(1-2m)=ζ_{Q(\sqrt{D})}(1-2m) at negative odd integers are also distributed as expected modulo p for any p. We use this heuristic to predict the computational time required to find quadratic analogues of irregular primes with a given order of magnitude. We also discuss alternative ways of collecting large amounts of data to test the heuristic.
