Photocathodic composite conductive polymer-titania films for use in solar hydrogen generation
Creators: name: Bruce, David R.
Publisher: name: University of British Columbia
Year: 2012

description: Green hydrogen generation can serve as a solution to energy storage needs of the 21st century if coupled with a renewable energy source such as solar power. There is an advantage to performing in-situ hydrogen generation at a photocatalytic surface in order to reduce system efficiency losses. Investigation into the limitations and benefits of coupled electrolytic and solar process are investigated in this dissertation. Of chief examination were polybithiophene-titania composite films used as a photocathode in a Nafion 117 membrane based H₂SO₄ electrolytic system. Titania content inclusion up to 0.35 mg/cm² with a range of film thicknesses between 1-20 μm, were investigated in several architectural configurations. The placement of the composite films was directed either towards or away from the proton conducing membrane in a 2-D or 3-D configuration. The results indicated that the electrochemical benefits to titania inclusion and film thickness increase were counter to photonic energy collection. With an increase in titania there was an increase in electrochemical performance, but it led to worse photonic efficiency as suspected due to an increase in recombination from defect trap states. With an increase in film thickness there was an increase in photonic efficiency with increased photon absorption, but this was accompanied by an increase in cell resistance leading to worse electrochemical performance. Electrochemical performance was also enhanced by placing the catalytic film directly against the membrane, although photonic stimulation in this configuration was impossible in our current cell configuration. Photonic stimulation was enhanced by the deposition of the composite films onto a distributed 3-D carbon fibre substrate. Doping of the 3-D composite films loaded on carbon fibre substrates with a Nafion ionomer interconnect was tested in an effort to enhance the triple phase connectivity of the cell. It was found that the doping resulted in a deactivation of the substrate (both electrochemical and photonic) due to the deposition method used, but increases in photonic performance at higher current densities showed that with less catalyst encapsulation this strategy may be a viable method to enhance PEM based photoelectrochemical cells.

description: The sustained rise in German unemployment since 1973 poses a problem of critical importance for the world economy. Fewer than two decades ago, Germany boasted an average unemployment rate of under 1% and imported labor to relieve chronic labor shortages. By the mid-1980s, unemployment had risen to over 8 percent of the labor force. This paper investigates some of the reasons for the secular rise in unemployment. We find that while deficient aggregate demand can probably explain some of the current joblessness, the secular rise in unemployment has consisted primarily of an increase in the equilibrium rate of unemployment. We also find little evidence that this increase is due to changes in frictional unemployment. Rather, after reviewing institutional details of the labor market in Germany, we identify various impediments to the kinds of structural adjustments that have operated to maintain a fairly constant equilibrium rate of unemployment in the United States.

description: Das Ziel der vorliegenden Dissertation war die Anwendung und Weiterentwicklung von Fluoreszenzfluktuationstechniken zur Untersuchung der Wechselwirkung von Proteinen mit Phospholipidmembranen, sowohl ihre Bindung an Lipiddoppelschichten als auch ihr Einbau in Lipidmonoschichten. Dazu wurde ein umfassendes Rahmenwerk von theoretischen Grundlagen an die spezifische Problemstellung angepasst und diese – besonders in Hinblick auf die Auswertung von Titrationsexperimenten – fortgeführt und wesentlich erweitert. Um eine effiziente und an die Erfordernisse der jeweiligen Experimente flexibel anpassbare Auswertung der Fluoreszenzdaten zu gewährleisten, wurde zudem ein Software-Korrelator nach dem mutiple tau-Prinzip programmiert und Skripte für die weitere Verwendung bei Bindungs- und Einbauexperimenten bereitgestellt.
description: The aim of this thesis was the application and further development of fluorescence fluctuation techniques to study the interaction of proteins with phospholipid membranes, both their binding to lipid bilayers and their insertion into lipid monolayers. For this purpose, a comprehensive framework of theoretical principles was adapted to the specific problems and - especially with regard to the evaluation of titration experiments - significantly expanded. In order to ensure an efficient evaluation of the fluorescence data that can be flexibly adapted to the requirements of the respective experiments, a software correlator was also programmed according to the mutiple tau principle and scripts were provided for further use in binding and insertion experiments.

description: Polypropylene is one of the most widely manufactured polymers and is produced via coordinative polymerization with metal-organic catalysts in different polymerization processes. Catalysts are continually developed and optimized, hence there is a constant need for kinetic studies of polymerization catalysts. Scope of this work is a kinetic study of two different Ziegler-Natta catalysts in a multi-step polymerization of propylene, consisting of a bulk-phase homo-polymerization and a subsequent gas-phase copolymerization of propylene and ethylene. For studying kinetics, an existing polymerization reactor has been equipped with a compensation heater to realize a calorimetric method for measurement of reaction kinetics in bulk polymerization conditions. The experimental results have been compiled in a phenomenological kinetic model. The purpose of the model is to describe polymerization kinetics and the resulting polymers with respect to the corresponding reaction conditions.
description: Polypropylen ist eines der meistgenutzten Polymere und wird über koordinative Polymerisation mit metall-organischen Katalysatoren in verschiedenen Verfahren hergestellt. Bei der koordinativen Polymerisation hängt die Kinetik der Reaktion von den verwendeten Katalysatoren ab, die stetig weiterentwickelt werden. Ziel dieser Arbeit ist eine kinetische Studie von zwei unterschiedlichen Ziegler-Natta Katalysatoren in mehrstufigen Polymerisationen Verfahren, das aus einer Homopolymerisation von Propylen in Masse und einer nachgeschalteten Copolymerisation von Propylen und Ethylen aus der Gasphase besteht. Zunächst wurde ein existierender Versuchsaufbau um eine Kompensations-heizung erweitert, um die Kinetik der Massepolymerisation mit Kalorimetrie untersuchen zu können. Abschließend ist basierend auf den Ergebnissen ein Modell entwickelt worden, mit dem die Kinetik der Polymerisation und die resultierenden Polymere in Abhängigkeit der Reaktionsbedingungen beschrieben werden kann.

description: The cosmic far-infrared background (CFIRB) is expected to be generated by faint, dusty star-forming galaxies during the peak epoch of galaxy formation. The anisotropy power spectrum of the CFIRB captures the spatial distribution of these galaxies in dark matter halos and the spatial distribution of dark matter halos in the large-scale structure. Existing halo models of CFIRB anisotropy power spectrum are either incomplete or lead to halo model parameters that are inconsistent with the galaxy distribution selected at other wavelengths. Here we present a conditional luminosity function approach to describe the far-IR bright galaxies. We model the 250 um luminosity function and its evolution with redshift and model-fit the CFIRB power spectrum at 250 um measured by the Herschel Space Observatory. We introduce a redshift dependent duty-cycle parameter so that we are able to estimate the typical duration of the dusty star formation process in the dark matter halos as a function of redshifts. We find the duty cycle of galaxies contributing to the far-IR background is 0.3 to 0.5 with a dusty star-formation phase lasting for \sim0.3-1.6 Gyrs. This result confirms the general expectation that the far-IR background is dominated by star-forming galaxies in an extended phases, not bright starbursts that are driven by galaxy mergers and last \sim10-100 Myrs. The halo occupation number for satellite galaxies has a power-law slope that is close to unity over 010^{10} L_Sun is 2\times10^{11}M_Sun and 3\times 10^{10}M_Sun at z=1 and 2, respectively. Integrating over the galaxy population with L_250>10^{9} L_Sun, we find that the cosmic density of dust residing in the dusty, star-forming galaxies responsible for the background anisotropies Ω_{dust}\sim3\times10^{-6} to 2\times10^{-5}.

description: A record is an entry in a time series that is larger or smaller than all previous entries. If the time series consists of independent, identically distributed random variables with a superimposed linear trend, record events are positively (negatively) correlated when the tail of the distribution is heavier (lighter) than exponential. Here we use these correlations to detect heavy-tailed behavior in small sets of independent random variables. The method consists of converting random subsets of the data into time series with a tunable linear drift and computing the resulting record correlations.

Organic redox catalysts for oxygen electroreduction to hydrogen peroxide : an application to drinking water treatment

description: Conventional H₂O₂ production entails an energy and capital intensive Riedl-Pfleiderer process, which is advantageous based on the economy of scale, yet it generates large amounts of toxic waste. The electrochemical synthesis of H₂O₂ can potentially emerge in small and remote applications, where the transportation and handling of concentrated H₂O₂ can be avoided. The commercial Dow-Huron electrolysis cell has shown some success in the pulp and paper industry. However, its highly caustic product (pH > 13) may limit its wide-spread application. Electrocatalytically, the two electron reduction of O₂ in near neutral or acidic media has proven challenging. In addition to cobalt macrocycle-based catalysts, quinone-based redox catalysts have also been successfully demonstrated as viable electrocatalysts. The present work reports the synthesis of a novel riboflavinyl-anthraquinone (RF-AQ) compound which showed redox catalytic activity for O₂ reduction to H₂O₂. Cyclic voltammetry with a rotating ring-disk electrode assembly was employed to characterize the catalyst. Chromoamperommetry experiments in a batch electrolysis cell were performed, using 0.5 M H₂SO₄ saturated with O₂, up to 24 hours at 21°C and 1barabs to demonstrate the longer term H₂O₂ synthesis. Modifications of the Vulcan XC72 by RF-AQ adsorption increased the onset potential of the O₂ reduction reaction by up to 50 mV compared to Vulcan XC72 alone. A H₂O₂ selectivity of up to 85 ± 5% was observed for the RF-AQ catalyst. Chronoamperommetry, via constant potential control at 0.1V vs. RHE, with the 10 wt% RF-AQ catalyst (composite loading of 2.5 mg cm⁻²) generated H₂O₂ with an initial rate (in two hours) of 21 µmol hr⁻¹ cm⁻² (normalized by the electrode geometric area) and accumulated up to 425 µmol cm⁻² (normalized by the electrode area) in 24 hours with a current density of about 1.3 mA cm⁻² at 70 ± 5% current efficiency. While the unmodified Vulcan XC72, with a similar catalyst weight loading and the same cathode potential, generated H₂O₂ with an initial rate of 6 µmol hr⁻¹ cm⁻² (normalized by electrode area) and accumulated only up to 140 µmol cm⁻² (normalized by electrode area) in 24 hours with a current density of about 0.55 mA cm⁻² at 55 ± 5% current efficiency.

Contractionary Devaluation, and Dynamic Adjustment of Exports and Wages

description: Recent macroeconomic models of developing countries have emphasized the possibility of contactionary devaluations, stressing that domestic aggregate demand is likely to be reduced by the devaluations while aggregate supply may respond only slowly to the change in relative prices brought about by the devaluation. These results have been obtained in static models. In this paper we add wage and export-sector dynamics to the models of contractionary devaluation, and show that the effects which produce contractionary devaluations in the short term can produce limit cycles in the long run. The economy never returns to long-run equilibrium following a devaluation, but rather moves with fixed periodicity through successive phases of boom and bust.

description: This paper presents a theoretical model to describe the effects of default risk on international lending to LDC sovereign borrowers. The threat of defaults in international lending is shown to give rise to many characteristics of the syndicated loan market: (1) quantity rationing of loans; (2) LDC policies designed to enhance creditworthiness; (3) prevalence of short maturities on international loans; and (4) a prevalence of bank lending relative to bond-market lending.

description: Die strukturellen und magnetischen Eigenschaften von M-Hexaferriten mit verschiedenen Kationenstöchiometrien wurden untersucht. Die Charakterisierungen erfolgten, sofern möglich, an Einkristallen der entsprechenden Verbindungen, welche aus Flux-Synthesen gewonnen wurden. Zur Strukturcharakterisierung wurde Röntgenbeugung an Pulvern und Einkristallen eingesetzt, die magnetische Charakterisierung erfolgte mittels umfangreicher Magnetisierungsmessungen in statischen (DC-) und alternierenden (AC-) Feldern. Die magnetische Anisotropie im System Ba1-xSrxFe12O19 wurde basierend auf feld- und richtungsabhängigen Messungen quantifiziert. Auch gelang erstmals eine Beschreibung Spin-Glas-ähnlicher sowie nicht kollinearer Magnetisierungszustände in scandium- und titansubstituierten Hexaferriten des M-Strukturtyps mit Hilfe von richtungsabhängigen AC-Messungen an orientierten Einkristallen. Auch die Kopplung von AC- mit DC-Feldern wird erörtert.
description: Structural and magnetic properties of M-hexaferrites with different cation stoichiometries have been investigated. If possible, all measurements were performed using single crystals that were grown by flux synthesis. Structural characterization was carried out via X-ray diffraction on powders and single crystals, respectively. Magnetic properties were studied using several magnetization measurements in alternating (AC-) and static (DC-) fields. The description and quantification of the magnetic anisotropy in the Ba1-xSrxFe12O19 system was achieved by the analysis of field dependent measurements. It was possible for the first time to investigate spin-glass-like and non-collinear magnetic structures in M-hexaferrites containing scandium and titanium via directional AC-measurements on single crystals. The implementation of coupled AC-DC-measurements is also discussed in detail.

description: The current crisis in international lending points up a lesson re-learned several times in the past 150 years: the international loan markets function very differently from the textbook model of competitive lending. This paper discusses various extensions of the basic model. First, we amend the textbook model to show how limitations on a government's taxing authority may greatly affect its optimal borrowing strategy. Second, we explore the implications of adebtor country's option to repudiate debt. Third, we show that efficient lending may require collective actions by bank syndicates, and that a breakdown in collective action can result in serious inefficiencies and even financial panics.

Most of them were accommodated at an abandoned military fort, Fort Napier, in Pietermaritzburg. Imprisonment caused disruptions and hardships for the internees but there is no evidence of the kind of excessive suffering that affected many prisoners of war (POWs) in other belligerent countries. Despite occasional outbursts of Germanophobia among British South Africans, the Afrikaner-dominated Union government treated the prisoners according to internationally accepted standards.

description: Questions surrounding the evolution of cooperation, especially human cooperation, have driven research in many disciplines. Two key methodologies used to research and explain the evolution of cooperation are modeling and narrative construction. A number of scientists and philosophers have suggested that advancing research on the evolution of cooperation will require integrating models and narratives. But, relatively little has been said about what challenges exist to integrating models and narratives, how to go about integrating models and narratives, and what particular benefits might be gained by accomplishing such integration. In this dissertation project, I address these questions in order to show how models and narratives can be integrated to produce better research on and explanations of the evolution of cooperation. The major challenge to integrating models and narratives concerning the evolution of cooperation that I address in this dissertation stems from the criticisms that such models and narratives lack empirical support. I answer this challenge by defending models and narratives from these criticisms. In the case of models, I argue both that at least some models of the evolution of cooperation have stronger empirical support than supposed by critics and that evolutionary robotics modeling approaches can be used to create even better models. In the case of narratives, I argue that several means of defending narratives from evidential challenges already developed by philosophers can be used to defend narratives about the evolution of cooperation as well. To show how narratives and models can be integrated to better research and explain the evolution of cooperation, I first establish an account of integration by drawing on the work of other philosophers. I then argue that models and narratives can provide certain benefits to each other via integration. Models can benefit from integration with narratives by using the narratives as sources of information as well as hypotheses to test. Indeed, as models are used to test such hypotheses, they also gain explanatory power. Narratives can benefit from integration with models by using the models as sources of support and constraint. Moreover, models can help deepen the understanding of historical contingency provided by narratives.

description: By solving the three-dimensional Gross-Pitaevskii equation we generate two-dimensional axially-symmetric and anisotropic dipolar Bose-Einstein condensate bright solitons, for repulsive atomic interaction, stabilized by only a weak one-dimensional optical lattice (OL) aligned along and perpendicular, respectively, to the dipole polarization direction. In the former case vortex solitons can also be created. We show that it is possible to make a stable array of small interacting axially-symmetric dipolar solitons put on alternate OL sites. Further, we demonstrate the elastic nature of the collision of two such solitons.

description: Discontent with the functioning of the world monetary system has led to many proposals for international monetary reform. These proposals range from enhanced consultations under the current regime of floating exchange rates to a regime of fixed exchange rates, as proposed by Ronald McKinnon. In this paper we examine the implications of several alternative monetary arrangements for fiscal policy in the world economy. In particular we focus upon two issues. The first is the effects of alternative monetary arrangements on the international transmission of fiscal policy. The second is the implications of the alternative regimes for strategic aspects of fiscal policymaking. As is generally the case in the discussion of exchange regimes we find that the choice of the monetary system is crucially dependent upon the source and nature of the shocks hitting the world economy. In this paper we show that the monetary regime also has important implications for the transmission of fiscal policy in the world economy and for the nature of the strategic games played by fiscal authorities. Rigid rules of the game, as under fixed exchange rates, do not necessarily eliminate the inefficient equilibria that can occur when fiscal authorities behave non-cooperatively.

description: The ultrafast and element-specific response of magnetic systems containing ferromagnetic 3d transition metals and 4d/5d heavy metals is of interest both from a fundamental as well as an applied research perspective. However, to date no consensus about the main microscopic processes describing the interplay between intrinsic 3d and induced 4d/5d magnetic moments upon femtosecond laser excitation exist. In this work we study the ultrafast response of CoFeB/Pt bilayers by probing element-specific, core-to-valence-band transitions in the extreme ultraviolet spectral range using high harmonic radiation. We show that the combination of magnetic scattering simulations and analysis of the energy- and time-dependent magnetic asymmetries allows us to accurately disentangle the element-specific response in spite of overlapping Co and Fe M2,3 as well as Pt O2,3 and N7 resonances. We find a considerably smaller demagnetization time constant as well as much larger demagnetization amplitudes of the induced moment of Pt compared to the intrinsic moment of CoFeB. Our results are in agreement with enhanced spin-flip probabilities due to the high spin-orbit coupling localized at the heavy metal Pt, as well as with the recently formulated hypothesis that a laser-generated, incoherent magnon population within the ferromagnetic film leads to an overproportional reduction of the induced magnetic moment of Pt.

description: By any standard, Bolivia's economic crisis in the 1980's has been extraordinary. Like its neighbors. Bolivia suffered from major external shocks, but the extent of economic collapse in the face of these shocks (including a hyperinflation during 1984-85) suggests that internal factors as well as external shocks have been critical to Bolivia's poor economic performance. One major theme of our work is that the recent economic crisis in Bolivia is a reflection of political and economic conflicts in Bolivian society that have undermined the development process throughout this century. While major reforms have been begun by the present government, many of the deepest problems in Bolivian society that contributed to the crisis remain unresolved.

description: Biomimetic surface coatings can be combined with conventional implants to mimic the extracellular matrix (ECM) of the surrounding tissue to make them more biocompatible. The layer-by-layer technique can be used for making surface coatings by alternating the adsorption of polyelectrolytes from aqueous solutions to form polyelectrolyte multilayers (PEM). In addition, cationic liposomes composed of OO4 and DOPE are promising systems for drug delivery and transfection system. Hence, two different approaches were combined to develop a functionalized surface coating: (i) a PEM surface coating that mimics the natural ECM of connective tissue by a combination of collagen type I and glycosaminoglycans such as chondroitin sulfate or hyaluronic acid and (ii) the immobilization of cargo-loaded liposomes using dexamethasone or lipoplexes with pDNA-BMP2 plasmid inducing osteogenesis for implant coating in the field of bone regeneration.
description: Biomimetische Oberflächenbeschichtungen können mit herkömmlichen Implantaten kombiniert werden, um die extrazelluläre Matrix (ECM) des umgebenden Gewebes nachzuahmen und sie biokompatibler zu machen. Layer-by-Layer-Technik kann zur Herstellung von Oberflächenbeschichtungen verwendet werden, indem Polyelektrolyte abwechselnd adsorbiert werden, um Polyelektrolyt-Multischichten (PEM) zu bilden. Darüber hinaus sind kationische Liposomen, die aus OO4 und DOPE bestehen, vielversprechende Systeme für die Verabreichung von Arzneimitteln und für Transfektionssysteme. Daher wurden zwei verschiedene Ansätze kombiniert, um eine funktionalisierte Oberflächenbeschichtung zu entwickeln: (i) eine PEM, die ECM des Bindegewebes durch eine Kombination von Kollagen Typ I und Chondroitinsulfat oder Hyaluronsäure nachahmt, und (ii) die Immobilisierung von frachtbeladenen Liposomen unter Verwendung Dexamethason oder lipoplexes von pDNA-BMP2 für die Implantatbeschichtung im Bereich der Knochenregeneration.

description: This paper provides a formal analysis of the current account balance in a dynamic model with optimizing agents. Two analytical ideas are stressed. First, an economy's current account balance depends as much on fixture economic trends as on the current economic environment. A shift in fiscal policy, for example, will have one effect on the current account if it is perceived to be temporary and another if it is seen to be permanent. Second, temporary disturbances in the economy have permanent effects, by altering the entire future path of the economy's international indebtedness.

description: A procedure was established and fully validated for the screening and quantification of fourteen synthetic antidiabetic adulterants in herbal pharmaceuticals and health foods, including metformin (MF), buformin (BF), phenformin (PHF), rosiglitazone (RGZ), pioglitazone (PGZ), chlorpropamide (CPM), glipizide (GPZ), tolbutamide (TBM), gliclazide (GCZ), glibenclamide (GBM), glimepiride (GMR), repaglinide (RGN), gliquidone (GQD) and nateglinide (NGN). The samples were extracted by methanol and separated by HPLC. Retention times and ultraviolet spectra were used for the preliminary screening, and the suspected adulterants were then confirmed by liquid chromatography-quadrupole-time of flight mass spectrometry (LC-Q-TOF-MS/MS) and quantified by HPLC. The developed procedure was successfully applied to assess twenty-four herbal samples, and PHF, GCZ, GBM, MF, GPZ and BF were found in many. To the best of our knowledge, this is the first report of simultaneous screening and quantification of these fourteen synthetic antidiabetic adulterants from any matrix.

A particle-based model for computing fluid flows and cell dynamics

description: The connection between certain human diseases and changes in the mechanical properties of living cells is well established, e.g. in the cases of malaria and cancer. However, the mechanism for the mechanical modifications, which tend to facilitate the pathogenesis of such diseases, is not always clear. For instance, the overall loss of deformability of malaria-infected red blood cells (RBCs) corresponds to a 10-fold increase in the rigidity of the cell membrane. On the other hand, micropipette aspiration has only measured a 3-fold increase in the elastic modulus. In this thesis, a particle-based model is developed to explore the interplay between the underlying microstructures and the behavior of the cell as a whole. The research consists of three related projects. The first project deals with the long-standing problem of Smoothed Particle Hydrodynamics (SPH) method with open boundaries and solid walls. We propose a "rotational pressure-correction scheme" with a consistent pressure boundary condition that leads to a large improvement in accuracy of calculated pressure and the drag coefficient on solid obstacles. The second and third projects concern developing a 2D and then 3D particle-based model for RBCs to explore the parasite-driven changes in malaria-infected RBCs. In our models the cell membrane is replaced by a set of discrete particles connected by linear or nonlinear springs. In addition, a linear bending elasticity is implemented using the deviation of the local curvature from the innate curvature of the biconcave shape of a resting RBC. The cytoplasm and the external liquid are modelled as homogeneous Newtonian fluids, and discretized by particles as in standard SPH solution of the Navier-Stokes equations. The malaria parasite is modelled as an aggregate of particles constrained to rigid-body motion. We argue that the discrepancy in the estimated elastic modulus of the membrane is caused by the presence of the rigid parasite particles inside infected cells, and have carried out numerical simulations to demonstrate this mechanism. Our three-dimensional simulation of RBC stretching tests by optical tweezers accurately demonstrates the compensating effects between the existence of malaria parasites and the elevated stiffness of the membrane on the overall deformability of infected RBC.

description: Experience with language plays a key role in language development for French immersion students. Multimodal, embodied literacy experiences are critical elements of language growth; thus it is imperative for educators to recognize their role in the development of language learning. Teachers can capitalize on children’s playful curiosities, explorations, and creations by recognizing their role in a child’s language journey and bringing considerations of children’s everyday desires into their pedagogical practice. The purpose of this study was to see how early years (kindergarten and grade 1) educators conceptualize multimodal, embodied learning experiences in their French immersion classrooms. Eight early years teachers were interviewed using semistructured interviews to inquire into their pedagogical practices. All of the teachers discussed the ways in which they create multimodal, embodied experiences to assist their students with language development. However, although the teachers reported affording their students these opportunities, none of them referred to these pedagogical experiences as multimodal or embodied literacies. Finally, teachers did not seem to separate oral or physical experiences from one another; teachers viewed that movement and voice must occur simultaneously for students to grasp the language activity. Lastly, none of the teachers agreed on the specific difficulties experienced by French immersion students, but unanimously stated that there is a substantial lack of resources for immersion educators. This void could be filled by multimodal, embodied literacy practices that students practice naturally throughout the day.

description: The effect on commercial banks of exposure to large amounts of developing country debt has been a topic of increasing concern in recent years. Fear of default on the part of the debtor countries has led to fears for the solvency of the creditor banks since in many cases the total of outstanding exposure to risky debtors exceeds the entire capital base of the banks involved. The paper presents a first effort towards measuring the effects of LDC debt exposure on the market value of large commercial value banks in the United States. Our results indicate that exposure to developing country debt has exerted a measurable and significant negative effect on the ratio of market to book value for these banks.
