description: This sub-thesis deals with the concentration of the European Community (EC) on the Common Agricultural Policy or CAP as its main policy to date, and the consequences of this for the process of integration. This process of integration is considered to be both economic and political, with both the economic welfare and the influence in international affairs of the integrated whole, the European Community, being greater than the sum of these from the individual parts, in this case the member states.

description: We investigate the universality of correlation functions of chaotic and disordered quantum systems as an external parameter is varied. A new, general scaling procedure is introduced which makes the theory invariant under reparametrizations. Under certain general conditions we show that this procedure is unique. The approach is illustrated with the particular case of the distribution of eigenvalue curvatures. We also derive a semiclassical formula for the non-universal scaling factor, and give an explicit expression valid for arbitrary deformations of a billiard system.

description: Transition metal dichalcogenides have emerged as promising materials for nano-photonic resonators due to their large refractive index, low absorption within a large portion of the visible spectrum and compatibility with a wide range of substrates. Here we use these properties to fabricate WS$_2$ double-pillar nano-antennas in a variety of geometries enabled by the anisotropy in the crystal structure. Using dark field spectroscopy, we reveal multiple Mie resonances, to which we couple WSe$_2$ monolayer photoluminescence and achieve Purcell enhancement and an increased fluorescence by factors up to 240. We introduce post-fabrication atomic force microscope repositioning and rotation of dimer nano-antennas, achieving gaps as small as 10$\pm$5 nm, opening the possibility to a host of potential applications including strong Purcell enhancement of single photon emitters and optical trapping, which we study in simulations. Our findings highlight the advantages of using transition metal dichalcogenides for nano-photonics by exploring new applications enabled by their unique properties.
Three Essays on Corporate Social Responsibility (CSR)

Social responsibility of business

Business enterprises--Ratings and rankings

description: This dissertation presents three essays in financial economics with regards to corporate social responsibility and ratings. The first essay develops the first model for the CSR rating agency who has incentives to shirk while the rated firms have incentives to manipulate information through deceptive public relations (greenwash). Depending on the size of the socially responsible investor base and its composition, three possible regimes can be inferred from the model. The first one is where the rating agency is catering to mainly a large group of sophisticated SR investors who compensate the rating agency for the value of information. The second one is where the rating agency is catering to mainly a large group of trusting SR investors who compensate the rating agency for the value of institutional certification. In either of these two regimes, the weight of the large group of SR investors should generate higher market valuations for higher-rated firms that motivate firm managers to perform greenwashing. The third regime is where there are just too few SR investors to justify the effort to produce informative signals and to drive apart market valuations for rated firms. The second essay investigates the empirical predictions of the model described in the first essay. I challenge the conventional wisdom of commercial CSR ratings being informative in a first attempt to understand how this ratings market operates. Using a novel difference-in-difference identification strategy, I show ratings significantly decreased for firms targeted by a regulatory crackdown on informational manipulation that inflates ratings. I find that better environmental ratings predict worse future corporate behavior via a novel set of benchmarks (i.e. penalties, lawsuits, and media coverage) while neither environmental nor social ratings appear to offer incremental predictive value beyond size and other standard firm characteristics. Higher-rated firms are associated with higher market valuations relative to their lower-rated counterparts. My findings point to a world in which the ratings business is primarily catering to a large group of trusting investors who buy ratings not for the value of information but for the value of institutional certification. The third essay examines the ratings of a recently emerged rating agency competitor and find its ratings are of no better predictive quality. I introduce a novel set of measures, `corporate badness (CB) ratings', for corporate environmental and social performance. In contrast to the leading commercial ratings, worse CB ratings correctly predict more future corporate bad behavior out-of-sample. These CB ratings provide a way to study ratings disagreement, which can be used to disentangle greenwashing from the other information contained in the leading commercial CSR ratings.
Galactic Binary Gravitational Wave Noise within LISA Frequency Band

description: Gravitational wave noise associated with unresolved binary stars in the Galaxy is studied with the special aim of determining the upper frequency at which it stops to contribute at the rms noise level of the proposed space-born interferometer (LISA). The upper limit to this background is derived from the statistics of SN Ia explosions, part of which can be triggered by binary white dwarf coalescences. The upper limiting frequency at which binary stochastic noise crosses LISA rms sensitivity is found to lie within the range 0.03-0.07 Hz, depending on the galactic binary white dwarf coalescence rate. To be reliably detectable by LISA, the energy density of relic cosmological background per logarithmic frequency interval should be Omega_{GW}h_{100}^2>10^{-8} at f>0.03 Hz.

description: The absorption spectra of the cold Na2 molecule dressed by a linearly polarized standing laser wave is investigated. In the studied scenario the rotational motion of the molecules is frozen while the vibrational and translational degrees of freedom are accounted for as dynamical variables. In such a situation a light-induced conical intersection (LICI) can be formed. To measure the spectra a weak field is used whose propagation direction is perpendicular to the direction of the dressing field but has identical polarization direction. Although LICIs are present in our model, the simulations demonstrate a very robust absorption spectrum, which is insensitive to the intensity and the wavelength of the dressing field and which does not reflect clear signatures of light-induced nonadiabatic phenomena related to the strong mixing between the electronic, vibration and translational motions. However, by widening artificially the very narrow translational energy level gaps, the fingerprint of the LICI appears to some extent in the spectrum.

description: We report on neutral hydrogen (HI) observations of the NGC 7232 group with the Australian Square Kilometre Array Pathfinder (ASKAP). These observations were conducted as part of the Wide-field ASKAP L-Band Legacy All-sky Blind surveY (WALLABY) Early Science program with an array of 12 ASKAP antennas equipped with Phased Array Feeds, which were used to form 36 beams to map a field of view of 30 square degrees. Analyzing a subregion of the central beams, we detect 17 HI sources. Eleven of these detections are identified as galaxies and have stellar counterparts, of which five are newly resolved HI galaxy sources. The other six detections appear to be tidal debris in the form of HI clouds that are associated with the central triplet, NGC 7232/3, comprising the spiral galaxies NGC 7232, NGC7232B and NGC7233. One of these HI clouds has a mass of M_HI ~ 3 x 10^8 M_sol and could be the progenitor of a long-lived tidal dwarf galaxy. The remaining HI clouds are likely transient tidal knots that are possibly part of a diffuse tidal bridge between NGC 7232/3 and another group member, the lenticular galaxy IC 5181.

description: A dilute gas of particles with short range interactions is considered in a shearing stationary state. A Gaussian thermostat keeps the total kinetic energy constant. For infinitely many particles it is shown that the thermostat becomes a friction force with constant friction coefficient. For finite number of particles N, the fluctuations around this constant are of order one over the square root of N, and distributed approximately Gaussian with deviations for large fluctuations. These deviations prohibit a derivation of fluctuation-dissipation relations far from equilibrium, based on the Fluctuation Theorem.

description: We consider the problem of modeling trajectories of drivers in a road network from the perspective of inverse reinforcement learning. Cars are detected by sensors placed on sparsely distributed points on the street network of a city. As rational agents, drivers are trying to maximize some reward function unknown to an external observer. We apply the concept of random utility from econometrics to model the unknown reward function as a function of observed and unobserved features. In contrast to current inverse reinforcement learning approaches, we do not assume that agents act according to a stochastic policy; rather, we assume that agents act according to a deterministic optimal policy and show that randomness in data arises because the exact rewards are not fully observed by an external observer. We introduce the concept of extended state to cope with unobserved features and develop a Markov decision process formulation of drivers decisions. We present theoretical results which guarantee the existence of solutions and show that maximum entropy inverse reinforcement learning is a particular case of our approach. Finally, we illustrate Bayesian inference on model parameters through a case study with real trajectory data from a large city in Brazil.

As anticipated by S. Mukhi, the method applies by induction to every coupling in the Chern--Simons action. It is also used to derive the corrections to the Dirac--Born--Infeld action at quadratic order in the field strength.

Limits of Eliashberg Theory and Bounds for Superconducting Transition Temperature
Creators: name: Sadovskii, M. V.
Publisher: name: arXiv
Year: 2021
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: The discovery of record - breaking values of superconducting transition temperature $T_c$ in quite a number of hydrides under high pressure was an impressive demonstration of capabilities of electron - phonon mechanism of Cooper pairing. This lead to an increased interest to foundations and limitations of Eliashberg - McMillan theory as the main theory describing superconductivity in a system of electrons and phonons. Below we shall consider both elementary basics of this theory and a number of new results derived only recently. We shall discuss limitations on the value of the coupling constant related to lattice instability and a phase transition to another phase (CDW, bipolarons). Within the stable metallic phase the effective pairing constant may acquire arbitrary values. We consider extensions beyond the traditional adiabatic approximation. It is shown that Eliasberg - McMillan theory is also applicable in the strong antiadiabatic limit. The limit of very strong coupling, being most relevant for the physics of hydrides, is analyzed in details. We also discuss the bounds for $T_c$ appearing in this limit.

description: This survey describes the method of approximation of operator semigroups, based on the Chernoff theorem. We outline recent results in this domain as well as clarify relations between constructed approximations, stochastic processes, numerical schemes for PDEs and SDEs, path integrals. We discuss Chernoff approximations for operator semigroups and Schrödinger groups. In particular, we consider Feller semigroups in $\mathbb{R}^d$, (semi)groups obtained from some original (semi)groups by different procedures: additive perturbations of generators, multiplicative perturbations of generators (which sometimes corresponds to a random time-change of related stochastic processes), subordination of semigroups / processes, imposing boundary / external conditions (e.g., Dirichlet or Robin conditions), averaging of generators, "rotation" of semigroups. The developed techniques can be combined to approximate (semi)groups obtained via several iterative procedures listed above. Moreover, this method can be implemented to obtain approximations for solutions of some time-fractional evolution equations, although these solutions do not posess the semigroup property.

Many clearly fail, including any in which the mass discrepancy appears at a particular length-scale. One hypothesis, MOND [Milgrom 1983, ApJ, 270, 371], is consistent with the data. Indeed, it accurately predicts the observed behavior. We find no evidence on any scale which clearly contradicts MOND, and a good deal which supports it.

Superlinear elliptic problems can be expected to have multiple positive solutions under certain situations. To our end, by conducting spectral analysis for the linearized eigenvalue problem at an unstable positive solution, we find sufficient conditions for ensuring that the implicit function theorem is applicable to the unstable positive one. An application of our results to the logistic boundary condition arising from population genetics is given.

description: Randomly-doped silicon has many competitive advantages for quantum computation; not only is it fast to fabricate but it could naturally contain high numbers of qubits and logic gates as a function of doping densities. We determine the densities of entangling gates in randomly doped silicon comprising two different dopant species. First, we define conditions and plot maps of the relative locations of the dopants necessary for them to form exchange interaction mediated entangling gates. Second, using nearest neighbour Poisson point process theory, we calculate the doping densities necessary for maximal densities of single and dual-species gates. We find agreement of our results with a Monte Carlo simulation, for which we present the algorithms, which handles multiple donor structures and scales optimally with the number of dopants and use it to extract donor structures not captured by our Poisson point process theory. Third, using the moving average cluster expansion technique, we make predictions for a proof of principle experiment demonstrating the control of one species by the orbital excitation of another. These combined approaches to density optimization in random distributions may be useful for other condensed matter systems as well as applications outside physics.

Search for heavy particles in the $b$-tagged dijet mass distribution with additional $b$-tagged jets in proton-proton collisions at $\sqrt{s} = 13$ TeV with the ATLAS experiment

description: A search optimized for new heavy particles decaying to two $b$-quarks and produced in association with additional $b$-quarks is reported. The sensitivity is improved by $b$-tagging at least one lower-$p_{\rm{T}}$ jet in addition to the two highest-$p_{\rm{T}}$ jets. The data used in this search correspond to an integrated luminosity of 103 $\text{fb}^{-1}$ collected with a dedicated trijet trigger during the 2017 and 2018 $\sqrt{s} = 13$ TeV proton-proton collision runs with the ATLAS detector at the LHC. The search looks for resonant peaks in the $b$-tagged dijet invariant mass spectrum over a smoothly falling background. The background is estimated with an innovative data-driven method based on orthonormal functions. The observed $b$-tagged dijet invariant mass spectrum is compatible with the background-only hypothesis. Upper limits at 95% confidence level on a heavy vector-boson production cross section times branching ratio to a pair of $b$-quarks are derived.

description: We point out, and draw some consequences of, the fact that the Poisson Lie group G* dual to G=GL_n(C) (with its standard complex Poisson structure) may be identified with a certain moduli space of meromorphic connections on the unit disc having an irregular singularity at the origin. The Riemann-Hilbert map for such connections, taking the Stokes data, induces a holomorphic map from the dual of the Lie algebra of G to the Poisson Lie group G*. The main result is that this map is Poisson. First this leads to new, more direct, proofs of theorems of Duistermaat and Ginzburg-Weinstein (enabling one to reduce Kostant's non-linear convexity theorem, involving the Iwasawa projection, to the linear convexity theorem, involving the `diagonal part'). Secondly we obtain a new approach to the braid group invariant Poisson structure on Dubrovin's local moduli space of semisimple Frobenius manifolds: it is induced from the standard Poisson structure on G*.

description: We present our analysis of the magnetic field structures from 6000 au to 100 au scales in the Class 0 protostar B335 inferred from our JCMT POL-2 observations and the ALMA archival polarimetric data. To interpret the observational results, we perform a series of (non-)ideal MHD simulations of the collapse of a rotating non-turbulent dense core, whose initial conditions are adopted to be the same as observed in B335, and generate synthetic polarization maps. The comparison of our JCMT and simulation results suggests that the magnetic field on a 6000 au scale in B335 is pinched and well aligned with the bipolar outflow along the east-west direction. Among all our simulations, the ALMA polarimetric results are best explained with weak magnetic field models having an initial mass-to-flux ratio of 9.6. However, we find that with the weak magnetic field, the rotational velocity on a 100 au scale and the disk size in our simulations are larger than the observational estimates by a factor of several. An independent comparison of our simulations and the gas kinematics in B335 observed with the SMA and ALMA favors strong magnetic field models with an initial mass-to-flux ratio smaller than 4.8. We discuss two possibilities resulting in the different magnetic field strengths inferred from the polarimetric and molecular-line observations, (1) overestimated rotational-to-gravitational energy in B335 and (2) additional contributions in the polarized intensity due to scattering on a 100 au scale.

This transition from evolutionary to non-evolutionary behavior arises as the global resource level is changed, and is reminiscent of a phase transition to a frozen state. Its origin lies in the inductive decision-making of the agents, the limited global information that they possess and the dynamical feedback inherent in the system.

description: This dissertation contains three essays on debts of different forms that make contributions to the areas of international macroeconomics and spatial economics. In particular, the first two essays study sovereign debts. They examine sovereign default behaviors together with interactions between sovereign defaults and countries’ costs of borrowing. The third essay looks at bank loans. It explores the possibility of understanding economic agglomeration through distance-related financial frictions firms face when borrowing from banks.
Security and identity in United States foreign policy : a reading of the Carter administration

subject: United States Foreign relations administration

description: The analysis in this thesis derives its impetus from three ‘windows of opportunity' present in current academic debates. The first is the opening made possible by the wide-ranging and interdisciplinary debate over the nature of social and political inquiry. The second, both an instance of and response to the first, is the theoretical confusion that currently exists in the discipline of International Relations. The third is the confusion that exists in the literature of International Relations concerning the reasons behind the Carter administration's foreign policy ‘failure’. These three openings are brought together in an account that reconceptualizes foreign policy in light of the interdisciplinary debate over the nature of social and political inquiry, offers a reinterpretation of United States foreign policy in the postwar era, and then seeks to account for the Carter administration in these new terms. The argument in this thesis is about the problematizations which make possible our understanding of global life. It seeks to demonstrate the particular problematization that makes possible the modes of analysis in the discipline of International Relations, the particular problematization that makes possible United States foreign policy, and the particular problematization that makes possible the conventional interpretation of the Carter administration. In this context, the discussion of the Carter administration’s foreign policy is not about its policy per se. Rather, it is about how its 'foreign policy' was made possible via a discursive economy that gave value to representational practices associated with a particular problematization. It is argued that ‘foreign polic/ needs to be understood as a political practice which establishes the boundary between the ‘domestic’ and the ‘international’, and brings a particular manifestation of both domains into existence. Foreign policy plays an important role in the creation and maintenance of a society’s identity through the transference of the differences within society to differences between societies. This is achieved via an inscription of danger (in what becomes the external realm), whereby the problems, fears and dangers of ‘man’ in ‘domestic’ society are externalized and totalized. What is at stake in foreign policy, therefore, is the defense of a particular identity through the writing of a particular understanding of security. Security, in this sense, refers to the issues involved in the inscription of danger. The thesis then brings this reconceputalization of foreign policy to bear upon postwar United States foreign policy, followed by a more detailed consideration of the Carter administration.

description: The Chemical and Biological Engineering (CHBE) building was selected for study from a number of buildings on the University of British Columbia campus whose occupants have made complaints about poor indoor air quality. As part of the training in the Occupational and Environmental Hygiene graduate program, students conducted an indoor environmental quality survey and performed field measurements for potential indoor air pollutants based on the result of the survey. Six occupants of the second floor answered survey questions regarding their perception of the quality of the indoor environment; the primary complaints were of chemical odours, particularly in the morning. Lack of ability to control temperature, and temperature fluctuation, was also noted by some respondents. Areas were chosen for sampling based on availability and in consultation with the safety program officer for the building. Assessment of airflow patterns and spot checks for bioaerosols, ultrafine particulate matter (≤ 1 μm), carbon dioxide, and volatile organic chemicals (VOCs) was conducted on March 16, 2010. A twenty‐four hour sample for carbon dioxide were taken March 16 – 17. Field measurement results showed that the level of indoor air contaminates in all sampling locations were in compliance with WorkSafe BC and ASHRAE 62.1 indoor air guidelines. However, the assessment of air flow patterns and generation of ultrafine particulate matter, may have contributed to subjective complaints by occupants Improvements to air flow patterns to enable fresh air delivery into occupied spaces, filtration of ultrafine particulate matter, and local control of room temperature may result in higher occupant satisfaction in this building.

Three Essays on Dynamic Pricing and Resource Allocation
Creators: Nur, Cavdaroglu
Publisher: name: Columbia University
Year: 2012
Subjects: Operations research

description: This thesis consists of three essays that focus on different aspects of pricing and resource allocation. We use techniques from supply chain and revenue management, scenario-based robust optimization and game theory to study the behavior of firms in different competitive and non-competitive settings. We develop dynamic programming models that account for pricing and resource allocation decisions of firms in such settings. In Chapter 2, we focus on the resource allocation problem of a service firm, particularly a health-care facility. We formulate a general model that is applicable to various resource allocation problems of a hospital. To this end, we consider a system with multiple customer classes that display different reactions to delays in service. By adopting a dynamic-programming approach, we show that the optimal policy is not simple but exhibits desirable monotonicity properties. Furthermore, we propose a simple threshold heuristic policy that performs well in our experiments. In Chapter 3, we study a dynamic pricing problem for a monopolist seller that operates in a setting where buyers have market power, and where each potential sale takes the form of a bilateral negotiation. We review the dynamic programming formulation of the negotiation problem, and propose a simple and tractable deterministic "fluid" analogue for this problem. The main emphasis of the chapter is in expanding the formulation to the dynamic setting where both the buyer and seller have limited prior information on their counterparty valuation and their negotiation skill. In Chapter 4, we consider the revenue maximization problem of a seller who operates in a market where there are two types of customers; namely the "investors" and "regular-buyers". In a two-period setting, we model and solve the pricing game between the seller and the investors in the latter period, and based on the solution of this game, we analyze the revenue maximization problem of the seller in the former period. Moreover, we study the effects on the total system profits when the seller and the investors cooperate through a contracting mechanism rather than competing with each other; and explore the contracting opportunities that lead to higher profits for both agents.
Conformal Higher Spin Theory

description: We construct gauge theory of interacting symmetric traceless tensor fields of all ranks s=0,1,2,3, ... which generalizes Weyl-invariant dilaton gravity to the higher spin case, in any dimension d>2. The action is given by the trace of the projector to the subspace with positive eigenvalues of an arbitrary hermitian differential operator H, the symmetric tensor fields emerge after expansion of the latter in power series in derivatives. After decomposition in perturbative series around a conformally flat point H=\Box, the quadratic part of the action breaks up as a sum of free gauge theories of symmetric traceless tensors of rank s with actions of d-4+2s order in derivatives introduced in 4d case by Fradkin and Tseytlin and studied at the cubic order level by Fradkin and Linetsky. Higher orders in interaction are well-defined. We discuss in detail global symmetries of the model which give rise to infinite dimensional conformal higher spin algebras for any d. We stress geometric origin of conformal higher spin fields as background fields of a quantum point particle, and make the conjecture generalizing this geometry to the system "tensionless d-1 brane + Fronsdal higher spin massless fields in d+1 dimensions". We propose a candidate on the role of Higgs-like higher spin compensator able to spontaneously break higher spin symmetries. At last, we make the conjecture that, in even dimensions d, the action of conformal higher spin theory equals the logarithmically divergent term of the action of massless higher spin fields on AdS_{d+1} evaluated on the solutions of Dirichlet-like problem, where conformal higher spin fields are boundary values of massless higher spin fields on AdS_{d+1}, the latter conjecture provides information on the full higher spin action in AdS_{d+1}.

description: Extremely metal-poor stars are keys to understand the early evolution of our Galaxy. The ESO large programme TOPoS has been tailored to analyse a new set of metal-poor turn-off stars, whereas most of the previously known extremely metal-poor stars are giant stars. Sixty five turn-off stars (preselected from SDSS spectra) have been observed with the X-Shooter spectrograph at the ESO VLT Unit Telescope 2, to derive accurate and detailed abundances of magnesium, silicon, calcium, iron, strontium and barium. We analysed medium-resolution spectra (R ~ 10 000) obtained with the ESO X-Shooter spectrograph and computed the abundances of several alpha and neutron-capture elements using standard one-dimensional local thermodynamic equilibrium (1D LTE) model atmospheres. Our results confirms the super-solar [Mg/Fe] and [Ca/Fe] ratios in metal-poor turn-off stars as observed in metal-poor giant stars. We found a significant spread of the [alpha/Fe] ratios with several stars showing sub-solar [Ca/Fe] ratios. We could measure the abundance of strontium in 12 stars of the sample, leading to abundance ratios [Sr/Fe] around the Solar value. We detected barium in two stars of the sample. One of the stars (SDSS J114424-004658) shows both very high [Ba/Fe] and [Sr/Fe] abundance ratios (>1 dex).

Entrepreneurship--Economic aspects
Entrepreneurship--Training of
Poor

description: While entrepreneurship is frequently touted as an engine for macroeconomic growth, and there is increasing policy interest in promoting entrepreneurship in lower-income countries, aspiring entrepreneurs in developing regions face unique constraints on their ability to grow successful businesses. This dissertation contains three empirical essays studying the factors that enable and constrain entrepreneurial growth in low-income contexts, drawing on data from a randomized field experiment studying an entrepreneurial training program in Zimbabwe. The first essay examines how entrepreneurial training impacts key hinge decisions on whether to continue pursuing an initial business idea, or to pivot to a new opportunity. The second essay studies how entrepreneurial training impacts subjective well-being, and the reasons why it might not track neatly with economic outcomes. The third essay studies innovation in the context of small informal enterprises, using text-based machine learning methods.
