description: An evolutionary process of the fast magnetic reconnection in ``free space'' which is free from any influence of outer circumstance has been studied semi-analytically, and a self-similarly expanding solution has been obtained. The semi-analytic solution is consistent with the results of our numerical simulations performed in our previous paper (see Nitta et al. 2001). This semi-analytic study confirms the existence of self-similar growth. On the other hand, the numerical study by time dependent computer simulation clarifies the stability of the self-similar growth with respect to any MHD mode. These results confirm the stable self-similar evolution of the fast magnetic reconnection system.

description: Excerpts from the report: This report evaluates sales effectiveness and efficiency of selected retail merchandising techniques for canned fruits and vegetables in retail food stores. The special displays appraised in this study were located at the end of the grocery gondola (shelves where cans are stacked). They were selected with the advice of the cooperating retailer as typical types of such displays currently in use and ranged from the informal jumbled display to the formally arranged pile-on display. Twelve supermarkets of a New England chain operating largely in the Boston metropolitan area were used for testing different methods of merchandising. The test stores had an annual gross sales volume per store averaging almost $2 million. Because all test stores were under one central management, it was possible to maintain a uniform price for each brand and size of items tested as well as of the substitute items, and to display the same number of brands and sizes of the test commodities throughout the study.

Essays in Economic and Corporate Finance

Economics

description: This dissertation consists of two distinct chapters. In the first chapter, I study the outsourcing of corporate governance to proxy advisory firms, which are third-party advisors that help institutional investors decide which way to vote on corporate governance issues. Advising equity assets in trillions of dollars, these advisors play a powerful role in shaping corporate governance. First, I model how conflicts of interest arise when a proxy advisor provides advisory services to investors as well as consulting services to corporations on the same governance issues. The advisor can issue biased voting recommendations when expected reputation costs are low, compared to consulting fees. I then study how increased competition can alleviate these conflicts. Using a unique dataset on voting recommendations, I show that the entry of a new advisory firm reduces favorable recommendations for management proposals by the incumbent advisor. This is consistent with our theory as the incumbent is subject to conflicts of interest by serving both investors and corporations. These results inform the policy debate on whether and how to regulate the proxy advisory industry.

The second chapter of the thesis assesses the value of access to public transportation in Beijing, a megacity suffering from severe traffic congestion. Existing urban economic theory states that traffic congestion is welfare reducing. In practice, policymakers in congested cities invest heavily in public transit systems to reduce transportation costs. However, not all public transit modes are created equal -- those that help alleviate traffic congestion are the most desirable. Using a unique panel dataset of Beijing's residential properties on sale between 2003 and 2005, I find strong evidence that traffic delays translate into lower housing prices, confirming that congestion is costly. Moreover, I show that announcements of metro line construction inflate prices of properties near future stations, and the increase is even more staggering for more congested areas. This suggests that metro lines are expected to reduce adverse impacts of congestion. However, additional bus routes are not capitalized into prices because buses move slowly in the gridlocked city, often exacerbating rather than alleviating congestion. These findings suggest that the overall quantity of public transit services does not necessarily increase welfare.

description: A central topic in empirical asset pricing is how to explain anomalies in various trading horizons. This dissertation contains two essays that study several anomalies in medium-term/long-term investment in the equity market and in high-frequency trading in the foreign exchange market. In the first essay, I propose an investor underreaction model with heterogeneous truncations across time and stocks. In this setting, investors are more attracted to dramatic changes in stock prices than to gradual changes. Continuous information causes signals to be truncated which delays their incorporation into stock prices thus generating momentum. Under the assumption that investors are more attracted to winner stocks and ignore more information in loser stocks, I show that a loser portfolio exhibits stronger momentum and higher profitability than a winner portfolio with the same discreteness level. A trading strategy based on this model yields high alphas and Sharpe ratios. Evidence from social media trends aligns well with this model. In the second essay, I develop multivariate logistic models to explain the short-term offer price movement of the currency pair EUR/USD from the EBS limit order book. Using logistic regression based methods, I study the impact of various market microstructure factors on offer price changes in the next second. The empirical results show explanatory power for the testing sample up to 45% and a true positive rate of the prediction up to 87%. The model reveals interesting mechanisms for the underlying driving forces of the tick-by-tick currency price movement.
RAMAN STUDIES OF METHANE-ETHANE HYDRATE STRUCTURAL TRANSITION

description: The inter-conversion of methane-ethane hydrate from metastable to stable structures was studied using Raman spectroscopy. To investigate factors controlling the inter-conversion, the rate of structural transition was measured at 59% and 93% methane in ethane. The observed slower structural conversion rate in the lower methane concentration atmosphere can be explained in terms of the differences in kinetics (mass transfer of gas and water rearrangement). Also, the effect of kinetic hydrate inhibitors, poly-N-vinylpyrrolidone (PVP) and polyethylene-oxide (PEO), on the hydrate metastability was investigated at 65% and 93% methane in ethane. PVP increased the conversion rate at 65% methane in ethane (sI is thermodynamically stable), but retarded the rate at 93% methane in ethane (sII is thermodynamically stable), indicating that the function of PVP depends on hydrate structure. PEO did not affect the structural transition considerably for either methane-ethane compositions.

Synchronized SETI - The Case for "Opposition"
Creators: name: Corbet, Robin H. D.
Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: If the signals that are being sought in SETI programs do exist but are very brief, for example because they are produced intermittently to conserve energy, then it is essential to know when these signals will arrive at the Earth. Different types of synchronization schemes are possible which vary in the relative amount of effort which is required by the transmitter and the receiver. Here the case is made for a scheme which is extremely simple for the receiver: make observations of a target when it is at maximum angular distance from the Sun (i.e. "opposition"). This strategy requires the transmitter to have accurate knowledge of the distance and proper motion of the Sun and the orbit of the Earth. It is anticipated that within about the next 10 to 20 years it will be possible to directly detect nearby extra-solar planets of approximately terrestrial mass. As any extraterrestrial transmitters are expected to have significantly more advanced technology it is therefore not unreasonable to expect that these transmitters would be able to detect the presence of the Earth and measure its orbit at even greater distances. In addition to the simplicity to the receiver of implementing this strategy it has the advantage that opposition is typically the time when observations are easiest to make anyway. A number of all-sky surveys that have already been performed naturally contain tiny "opposition surveys" within them. A full all-sky opposition survey would require extensive time to complete with a single moderate field of view telescope but different types of arrays might be employed instead including some systems already under construction.

Moreover, we prove that the limit does not depend on the particular choice of $h$ as long as it integrates to a constant value.

Abstract:
Sea level rise (SLR) is a potentially devastating process for coastal communities, and many are not adequately prepared. Lacking perfect SLR information, communities must plan and prepare using imperfect information, subject to the needs and preferences of the community. This study identified public and local officials’ preferences for SLR planning in coastal communities on the East Coast of the United States. A survey of over 500 individuals who live in, work in, or regularly visit coastal communities on the East Coast of the United States identified preferred components needed for planning, funding, and conflict resolution methods around SLR plans. Interviews with public officials on Long Beach Island, New Jersey addressed the utility of the survey results to address community needs to reduce SLR risks, protect key assets, and identify local protection priorities. Six key findings describe public preferences on what to include in a plan (such as prioritizing critical infrastructure), methods to reduce conflict (such as discussions with scientists) funding methods, and other components of a community-based sea level rise plan. This work will help communities to build SLR plans to meet their needs while breaking down policymaking barriers.

description: Eco-climatic niche models are powerful tools for assessing the potential range of plant pests and pathogens, widely applied in comprehensive pest risk assessments globally. We conducted a bibliometric analysis comparing the number of CLIMEX models developed for plant pathogens and plant arthropod pests. We found that plant pathogens were statistically significantly under-represented, with fungal plant pathogens less than half as likely as plant insect pests to be the subject of a published CLIMEX niche model. We explore key factors that may account for this disparity, including inconsistent experimental paradigms and lack of cross-disciplinary (i.e., plant pathology and modelling) expertise.

description: Spatial distributions models (SDM) are often used in invasive pest management to understand current and potential distribution. Using data on the well-studied spotted wing drosophila as a model, we compared distribution patterns of the range-limit with commonly applied correlative and mechanistic models. Correlative models risk underestimation whereas simple mechanistic models provide overestimated range predictions, although using both approaches for the spotted wing drosophila improved range-limit predictions. Model choice when dealing with pests is central to the accurate identification of invasive species limit range and consequently for the deployment of monitoring and early detection programs.

Similar to the Sagnac effect, their sensitivity increases with the space-time area enclosed by the interferometer. Here, we introduce twin-lattice atom interferometry exploiting Bose-Einstein condensates. Our method provides symmetric momentum transfer and large areas in palm-sized sensor heads with a performance similar to present meter-scale Sagnac devices.

 Comments: Amietia angolensis is known from almost all of Angola, but chiefly from the northern and western regions (Marques et al. 2018). Ferreira (1904) cited two adult specimens from “N’dalla Tando” and possibly one from “Zembe”, matching the records for MHNCUP/ANF 192 and MHNCUP/ANF 193, ANF 195–196. The remaining extant specimens have no locality associated. A. angolensis has been restricted to Angolan populations by Channing & Baptista (2013) and Channing et al. (2016), although it might have a broader distribution (Marques et al. 2018). Ernst et al. (2020) recently cited the species from Serra do Pingano, Uíge Province. Amietia angolensis was also recently cited from northeastern Democratic Republic of the Congo (Mali et al. 2019), but that identification needs confirmation (Frost 2020).

description: In science and medicine, model interpretations may be reported as discoveries of natural phenomena or used to guide patient treatments. In such high-stakes tasks, false discoveries may lead investigators astray. These applications would therefore benefit from control over the finite-sample error rate of interpretations. We reframe black box model interpretability as a multiple hypothesis testing problem. The task is to discover "important" features by testing whether the model prediction is significantly different from what would be expected if the features were replaced with uninformative counterfactuals. We propose two testing methods: one that provably controls the false discovery rate but which is not yet feasible for large-scale applications, and an approximate testing method which can be applied to real-world data sets. In simulation, both tests have high power relative to existing interpretability methods. When applied to state-of-the-art vision and language models, the framework selects features that intuitively explain model predictions. The resulting explanations have the additional advantage that they are themselves easy to interpret.

In this paper we simplify his constructions and express them by using noncommutative generalizations of determinants introduced by Gelfand and Retakh. In particular, for every finite-dimensional module N over the algebra of noncommutative polynomials of m variables we construct a characteristic rational power series chi(N). If N is an algebraically closed field of arbitrary characteristic and N is semisimple, the series chi(N) determines N.

description: Differential scanning calorimetry has been used to study the kinetics of formation of clathrate hydrates in the systems water-CCl3F and water-CH4, in which the water phase was dispersed in an oil phase in the form of an emulsion. CCl3F hydrates were formed at ambient pressure and constant temperatures of -10, -15 and -20 °C. The results showed that the crystallization of both ice and hydrate are in competition at the lowest temperature, whereas only hydrate is formed at -10 or -15 °C. CH4 hydrates were studied using a high-pressure DSC in the range 10 to 40 MPa, at various temperatures. At high driving force, the heat peak related to the formation of hydrates has a regular and symmetric shape, and its height and width depend on the gas pressure and sub cooling degree. At near equilibrium conditions, hydrate formation can be delayed by several hours, but is still clearly observable. A model based on crystal growth theory coupled with a statistical law to take into account the germination in micro sized droplets is proposed.

Chondrodactylus pulitzerae

description: Chondrodactylus pulitzerae (Schimdt, 1933)
 Material (seven specimens): Five adult specimens (MHNCUP/REP 201–205, formerly UP-MHNFCP-094992; Fig. S27), collected from Bahia dos Tigres [=Baía dos Tigres] [-16.58559º, 11.82709º, 98 m a.s.l.] Namibe Province, in 1905; one adult specimen (MHNCUP/REP 206, formerly UP-MHNFCP-018321), collected from unknown locality, date unknown; one adult specimen (MHNCUP/REP 207, formerly UP-MHNFCP-017359), collected from Bahia dos Tigres [= Baía dos Tigres] [-16.58559º, 11.82709º, 98 m a.s.l.] Namibe Province, in 1905.
 Comments: Chondrodactylus pulitzerae occurs along the Angolan coast, mainly in the south of the country (Marques et al. 2018), with Caop Velha, Bengo Province, being the known northern limit of distribution (Ceríaco et al. 2017). Heinz (2011) demonstrated that C. pulitzerae was the correct name for the Angolan lineage. Specimens from the Newton expedition were never cited before. MHNCUP/REP 201–205 specimens’ jar was labelled as “ Pachydactulus bibroni (Smith) Newton Bahia dos Tigres 1905 ” and “11 Baía dos Tigres 1905”. This matches the known distribution of the species, as C. pulitzerae has already been cited from Namibe Province (Bocage 1895; Ceríaco et al. 2016b; Laurent 1964).

description: Using the framework for multiplicative parametrized homotopy theory introduced in joint work with C. Schlichtkrull, we produce a multiplicative comparison between the homotopical and operator algebraic constructions of twisted K-theory, both in the real and complex case. We also improve several comparison results about twisted K-theory of C*-algebras to include multiplicative structures. Our results can also be interpreted in the infinity-categorical setup for parametrized spectra.

description: Tris-bipyridine ferrous complexes having β-lactosides, β-maltosides or α-mannosides with serinol spacers were prepared as molecular mimics of densely packed carbohydrate clusters on cell surfaces. Conformational analysis on these glycosylated complexes were conducted by UV–vis and circular dichroism spectroscopy measurements, which disclosed that the chloride, nitrate and sulfate salts induced the conformational changes of the glycosylated complexes in the anion- and carbohydrate-dependent manners.

description: This dissertation studies topics in the areas of empirical corporate finance, banking, and financial intermediation. In the first chapter, entitled Personal Relationships in Loan Renegotiation: Evidence from Corporate Loans, I estimate the effect of personal relationships between a loan officer and a firm on the probability to renegotiate a loan and the outcomes of the renegotiation. To identify this effect, I exploit a bank reorganization in Greece in the mid-2010s, which allows me to identify two types of firms: one, those whose personal relationships with loan officers were discontinued and those whose relationships were not. This paper’s main conclusion is that personal relationships mitigate the cost of distress for the firm in a loan renegotiation. The firm is worse off following the interruption of its loan officer relationship, as it is less able to renegotiate, and the firm also receives tougher loan terms on renegotiated loans. The insights from the second chapter, entitled Lending Relationships and Moral Hazard in Loan Renegotiation, can have important policy implications related to the rise of nonperforming loans (NPLs). Many banks operating in countries that were hit by the 2010 European debt crisis, faced a significant rise in NPLs. This rise became one of the main challenges that banks face, as high levels of NPLs tie up bank capital and thus reduce profitability and increase funding costs. In the second chapter, I provide empirical evidence that banks, through efficient renegotiation and strong relationships with firms, can prevent loan defaults. This analysis suggests that firms with more distant lending relatioships are more likely to strategically delay a loan payment in order to efficiently trigger a loan renegotiation. This strategic behavior gives rise to the moral hazard phenomenon. In the third chapter, entitled Securing the Unsecured: Do stronger creditor rights affect firms’ access to credit?, I seek to understand whether stronger creditor rights influence firms’ capital structure and access to finance. To answer this question, I use the passage of an enforcement on cash assets reform in Croatia that aimed to increase the collection of the unsecured debt. To identify exogenous variation across firms affected more by the reform versus those that were not, I use a novel dataset on courts’ efficiency in dealing with the specific type of cases affected by the reform. The conclusion of the paper is that firms maintain higher leverage and have easier access to credit when creditor rights are stronger. The firms that benefit the most are medium size and have limited access to tangible assets. When firms are able to borrow more, they invest more in fixed assets.
Skew Young diagram method in spectral decomposition of integrable lattice models II: Higher levels

description: The spectral decomposition of the path space of the vertex model associated to the level $l$ representation of the quantized affine algebra $U_q(\hat{sl}_n)$ is studied. The spectrum and its degeneracy are parametrized by skew Young diagrams and what we call nonmovable tableaux on them, respectively. As a result we obtain the characters for the degeneracy of the spectrum in terms of an alternating sum of skew Schur functions. Also studied are new combinatorial descriptions (spectral decomposition) of the Kostka numbers and the Kostka--Foulkes polynomials. As an application we give a new proof of Nakayashiki--Yamada's theorem about the branching functions of the level $l$ basic representation $lΛ_k$ of $\hat{sl}_n$ and a generalization of the theorem.

X-ray versus Optical Observations of Active Galactic Nuclei: Evidence for Large Grains?
Creators: name: Weingartner, Joseph C.

description: Recently, Maiolino et al. (2001a, A&A, 365, 28) constructed a sample of active galactic nuclei for which both the reddening E(B-V) and the column density N_H to the nucleus could be determined. For most of the galaxies in their sample, they found that E(B-V)/N_H is substantially smaller than for the diffuse ISM of our Galaxy. They asserted that either the dust-to-gas ratio is lower than in the Galaxy or that the grains are so large that they do not extinct or redden efficiently in the optical. We show that there is no systematic increase in E(B-V) with N_H for the Maiolino et al. (2001a) galaxies, which suggests that the X-ray absorption and optical extinction occur in distinct media. Maiolino et al. (2001b, A&A, 365, 37) suggested that the observed lines of sight for the Maiolino et al. (2001a) galaxies pass through the ``torus'' that obscures the broad line region and nuclear continuum in Seyfert 2 galaxies and argued that the torus grains are larger than Galactic grains. There is no reason to believe that the lines of sight for these galaxies pass through the torus, since the observed column densities are lower than those typically observed in Seyfert 2 galaxies. We suggest instead that the X-ray absorption occurs in material located off the torus and/or accretion disk while the optical extinction occurs in material located beyond the torus. The X-ray absorbing material could either be dust-free or could contain large grains that do not extinct efficently in the optical. There is no conclusive evidence that the grains in active galactic nuclei are systematically larger than those in the diffuse ISM of our Galaxy.

Deposit insurance

description: This dissertation studies empirical corporate finance problems of regulations and monitoring. The dissertation is composed of three chapters. First, I study how firms deal with business regulations that limit their operations. In the first chapter I exploit a natural experiment in Argentina to show that the ownership structure of a firm affects its degree of compliance with regulations, with publicly listed firms complying more than privately held ones. In 2012 the Argentine government banned companies from transferring funds abroad from their domestic operations. Despite this limitation, companies trying to repatriate capital could still overprice products they import from their headquarters or affiliates. I find that after the regulation, private firms overprice imports by almost 10% and manage to repatriate up to 46% of the profits that would have otherwise remained locked in at the Argentine subsidiary. Listed companies do not exploit this mechanism, showing that listing status affects compliance.
      The second chapter studies whether the differential cost imposed on listed firms operating in emerging markets by these higher compliance rates is significant. The main empirical challenge is that the cost is firm-time-regulation specific, and, for that reason, it is empirically unfeasible to measure it. I take an alternative route and show that changes in the levels of market regulations impose compliance costs of such magnitude that they shape the patterns of M&A transactions. First, I show that after the regulation studied in Chapter 1, private firms acquired listed ones at an extraordinary pace, while listed firms stopped acquiring private ones. This evidence suggests that the regulation increased the cost of being public. Then, I show that this finding is not specific to the Argentine market but is common across emerging markets. I do so by analyzing the response of M&A transactions to changes in the regulatory intensity of each country.
      Finally, the third chapter, co-authored with Matthieu Chavaz, studies the effect of deposit insurance on market discipline in a close-to-ideal setting. We exploit the political relationship between the United Kingdom and its Crown Dependencies and use a novel dataset to test this effect. Tracking the price paid for thousands of deposit products between 2007 and 2015, we find that deposit insurance deters discipline. In addition, we provide the first direct test of the interaction between depositors’ attention, deposit insurance, and market discipline. We show that when attention increases, risky banks offer higher rates both to insured and uninsured depositors, but that the effect is stronger for uninsured depositors. These results suggest that discipline is imposed even in the presence of deposit insurance, but only when information becomes salient.
