Does Subordinated Debt Discipline Banks? Empirical Evidence of Market Discipline in Europe
Creators: name: Schürk, Daniel
Publisher: name: Junior Management Science
Year: 2019

description: This thesis provides a differentiated answer to the question whether subordinated debt disciplines bank’s risk-taking behavior. I investigate the conditions and applicability of market discipline through subordinated debt instruments by critically reviewing the state of research. Relating to the regulatory context, I discuss proposals and various empirical studies and find that subordinated debt is an adequate measure to discipline banks under certain conditions. 
My own empirical analysis contributes to evidence provided by prior studies and updates them for the European case. I conclude that subordinated debt investors perceive differences in risk between banks and across time and are sensitive to credit ratings and accounting variables at generally higher spread levels compared to senior bonds. Results include that spread is positively sensitive (increases with respect to one standard error) to equity to capital (225 BPS), provision for loan losses (200 to 225 BPS), non-performing loans to equity (400 to 715 BPS) and interest coverage ratio (60 BPS). Spread is negatively sensitive (decreases with respect to one standard error) to ROA (120 BPS) and loan loss reserves (360 to 620 BPS).

description: We discuss the action of O(d,d), and in particular T-duality, in the context of generalized geometry, focusing on the description of so-called non-geometric backgrounds. We derive local expressions for the pure spinors descibing the generalized geometry dual to an SU(3) structure background, and show that the equations for N=1 vacua are invariant under T-duality. We also propose a local generalized geometrical definition of the charges f, H, Q and R appearing in effective four-dimensional theories, using the Courant bracket. We then address certain global aspects, in particular whether the local non-geometric charges can be gauged away in, for instance, backgrounds admitting a torus action, as well as the structure of generalized parallelizable backgrounds.

The Impact of the Organic Label Halo Effect on Consumers’ Quality Perceptions, Value-in-Use and Well-Being
Creators: name: Küst, Philipp
Publisher: name: Junior Management Science
Year: 2019

description: Food well-being is an innovative field of research analysing the complex consequences of food intake on body and mind. In face of mounting civilization diseases and environmental challenges promoting healthy and sustainable diets is crucial. For consumers it is difficult however, to assess the healthiness and environmental friendliness of a product. Food labels, like the organic one, are therefore used as extrinsic cues to help customers distinguish between alternatives. 
This paper analyses how the organic label biases consumers’ quality perception, a phenomenon that has been referred to as the organic label halo effect. It further intends to uncover the links between several quality dimensions and their consequences as reflected in value-in-use. Finally it aims to detect if those consequences ultimately lead to enhanced post-prandial wellbeing. 
A quantitative study in an experimental canteen setting was conducted to answers those questions. Structural equation modelling (SEM) was applied to test the hypotheses. The results indicate a positive impact of the organic label halo effect on consumers’ quality perceptions in terms of health & safety, environmental friendliness & animal welfare as well as prestige. Those in turn were shown to positively influence on several value-in-use dimensions, including social, altruistic, functional and hedonic value. Finally, the latter two were significantly related to well-being. 
Hence, this research shows that providing organic food in a canteen ultimately enhances consumer well-being through inferential beliefs on quality and value evoked by the label. The findings help to better understand the links between food consumption and subjective well-being and are therefore of interest for policy makers and researchers around the world.

description: This research aims to derive the average run length (ARL) evaluation of the double exponentially weighted moving average (double EWMA) control chart for observation data that follows exponential white noise in a time series model with an autoregressive model. Since most real-world data is automatically correlated, autoregressive models are available. Comparisons were made between the ARLs obtained using the explicit formula and the numerical integral equation (NIE) approach. The results showed that the explicit formula's use of the ARL outperformed the NIE approach in terms of computation time. After that, the efficacy of the exponentially weighted moving average (EWMA) and double EWMA charts is then compared using the suggested explicit ARL formula. The ARL of the double EWMA chart was found to perform better than the ARL of the EWMA chart in all situations. It also uses natural gas and diesel prices on stock exchanges around the world as cases studies. The results show that the double EWMA chart has better detection sensitivity than the EWMA chart, and the results are consistent with the experimental results. As a result, the sensitivity of the double EWMA chart in detecting changes makes it a good alternative for monitoring processes with real-world data.

description: In order to run Computational Fluid Dynamics (CFD) codes on large scale infrastructures, parallel computing has to be used because of the computational intensive nature of the problems. In this paper we investigate the ADAPT platform where we couple flow Partial Differential Equations and a Poisson equation. This leads to a linear system which we solve using direct methods. The implementation deals with the MUMPS parallel multi-frontal direct solver and mesh partitioning methods using METIS to improve the performance of the framework. We also investigate, in this paper, how the mesh partitioning methods are able to optimize the mesh cell distribution for the ADAPT solver. The experience gained in this paper facilitates the move to the 3D version of ADAPT and the move to a Service Oriented view of ADAPT as future work.

Our results show good agreement with the recent simulation data of Brown et al. and of other similar computer experiments on the Jellium model at high density and low temperature. Our algorithm can be used to treat any quantum fluid model of fermions at finite, non zero, temperature and has never been used before in literature.

Charakteristika vs. Carry - Outperformance in Devisenmärkten

description: Die optimale Währungsallokation ist eine der Kernfragen des international agierenden Investors. Ich teste in diesem Zusammenhang empirisch den Mehrwert des Portfoliooptimierungsverfahrens von Brandt et al. (2009) im Devisenkontext und vergleiche das Ergebnis mit einer diversifizierten Carry-Strategie und weiteren Benchmarks. Da im Zuge dieses Verfahrens sogenannte Charakteristika als Inputsignale für die Allokation benötigt werden, selektiere ich auf Basis bereits vorhandener Literatur zur Prädiktabilität von Währungsrenditen die Faktoren Carry, Momentum, realer Wechselkurs, Leistungsbilanzsaldo, Produktionslücke und Volatilität und untersuche die Performance der auf Basis dieser Signale generierten Portfolios über den Zeitraum von Anfang 1990 bis Ende 2017. Ich finde die stärkste Evidenz für Carry, aber auch Momentum, der reale Wechselkurs und der Leistungsbilanzsaldo wirken mitunter als Signal für die Allokation der optimalen Portfoliogewichte interessant. Ebenfalls kann ich feststellen, dass die Profitabilität beinahe aller untersuchten Strategien maßgeblich vom gewählten Anlageuniversum abhängt, wobei bei gegebener Datenverfügbarkeit eine breite Definition mit Industrie- und Entwicklungsländern zu bevorzugen ist. Des Weiteren kann ich teils interessante Diversifikationseigenschaften und positive Wechselwirkungen zwischen den Charakteristika dokumentieren, welche sich durch Kombination mittels des gewählten Optimierungsansatzes realisieren lassen. Auch stelle ich fest, dass Transaktionskosten im Schnitt einen wesentlichen negativen Einfluss auf die Renditen der Strategien haben. Die Sensibilisierung des Verfahrens durch Inklusion eines entsprechenden Transaktionskostenterms führt jedoch zu einer Performance-Regeneration.

description: We extend the Sakai-Sugimoto holographic model of QCD (HQCD) by including the scalar bi-fundamental "tachyon" field in the 8-brane-anti-8-brane probe theory. We show that this field is responsible both for the spontaneous breaking of the chiral symmetry, and for the generation of (current algebra) quark masses, from the point of view of the bulk theory. As a by-product we show how this leads to the Gell-Mann- Oakes-Renner relation for the pion mass.

description: We analyse nonperturbatively signal transmission patterns in Green's functions of interacting quantum fields. Quantum field theory is re-formulated in terms of the nonlinear quantum-statistical response of the field. This formulation applies equally to interacting relativistic fields and nonrelativistic models. Of crucial importance is that all causality properties to be expected of a response formulation indeed hold. Being by construction equivalent to Schwinger's closed-time-loop formalism, this formulation is also shown to be related naturally to both Kubo's linear response and Glauber's macroscopic photodetection theories, being a unification of the two with generalisation to the nonlinear quantum-statistical response problem. In this paper we introduce response formulation of bosons; response reformulation of fermions will be subject of a separate paper.

description: We report a comprehensive analysis of the ground state properties of axisymmetric toroidal crystals based on the elastic theory of defects on curved substrates. The ground state is analyzed as a function of the aspect ratio of the torus, which provides a non-local measure of the underlying Gaussian curvature, and the ratio of the defect core-energy to the Young modulus. Several structural features are discussed,including a spectacular example of curvature-driven amorphization in the limit of the aspect ratio approaching one. The outcome of the elastic theory is then compared with the results of a numerical study of a system of point-like particles constrained on the surface of a torus and interacting via a short range potential.

description: OH(1720 MHz) and methanol masers are now recognized to be excellent probes of the interactions of supernova remnants with molecular clouds and tracers of massive star formation, respectively. To better understand the nature of star formation activity in the central region of the Galaxy, we have used these two classes of masers combined with the IRAC and MIPS data to study prominent sites of ongoing star formation in the nuclear disk. The nuclear disk is characterized by massive GMCs with elevated gas temperatures, compared to their dust temperatures. We note an association between methanol masers and a class of mid-infrared ``green sources''. These highly embedded YSOs show enhanced 4.5micron emission due to excited molecular lines. The distribution of methanol masers and supernova remnants suggest a low efficiency of star formation (with the exception of Sgr B2), which we believe is due to an enhanced flux of cosmic ray electrons impacting molecular clouds in the nuclear disk. We also highlight the importance of cosmic rays in their ability to heat molecular clouds, and thus increase the gas temperature.

description: We present the results of the modelling of CO adsorption and catalytic CO oxidation on inhomogeneous Pt(100) surfaces which contain structurally different areas. These areas are formed during the CO-induced transition from a reconstructed phase with hexagonal geometry of the overlayer to a bulk-like (1x1) phase with square atomic arrangement. In the present approach, the surface transition is explained in terms of nonequilibrium bistable behavior. The bistable region is characterized by a coexistence of the hexagonal and (1x1) phases and is terminated in a critical bifurcation point which is located at (T_c ~680 K, p_CO ~10 Torr). Due to increasing fluctuations, the behavior at high temperatures and pressures in the vicinity of this cusp point should be qualitatively different from the hysteresis-type behavior which is typically observed in the experiments under ultrahigh vacuum conditions. On the inhomogeneous surface, we find a regime of nonuniform oscillations characterized by random standing waves of adsorbate concentrations. The resulting spatial deformations of wave fronts allow to gain deeper insight into the nature of irregular oscillations on Pt(100) surface.

description: Presentation at the IUP (Institute for Environmental Physics at University of Bremen) - AWI (Alfred Wegener Institute) block seminar on "Polar Amplification" on 30.09.2020 online. The main result of the coordinated atmosphere-only experiments carried out within the Polar Amplification Model Intercomparison Project (PAMIP) is that regional details of an atmospheric response to declined Arctic sea ice are not robust. Also very high horizontal and vertical resolutions do not change this conclusion. Differences between 100 ensemble member packs within a 300 member ensemble are as large as differences between different resolutions.

description: Vision is known to improve human postural responses to external perturbations. This study investigates the role of vision for the responses to continuous pseudorandom support surface translations in the body sagittal plane in three visual conditions: with the eyes closed (EC), in stroboscopic illumination (EO/SI; only visual position information) and with eyes open in continuous illumination (EO/CI; position and velocity information) with the room as static visual scene (or the interior of a moving cabin, in some of the trials). In the frequency spectrum of the translation stimulus we distinguished on the basis of the response patterns between a low-frequency, mid-frequency, and high-frequency range (LFR: 0.0165-0.14 Hz; MFR: 0.15-0.57 Hz; HFR: 0.58-2.46 Hz). With EC, subjects' mean sway response gain was very low in the LFR. On average it increased with EO/SI (although not to a significant degree p = 0.078) and more so with EO/CI (p < 10-6). In contrast, the average gain in the MFR decreased from EC to EO/SI (although not to a significant degree, p = 0.548) and further to EO/CI (p = 0.0002). In the HFR, all three visual conditions produced, similarly, high gain levels. A single inverted pendulum (SIP) model controlling center of mass (COM) balancing about the ankle joints formally described the EC response as being strongly shaped by a resonance phenomenon arising primarily from the control's proprioceptive feedback loop. The effect of adding visual information in these simulations lies in a reduction of the resonance, similar as in the experiments. Extending the model to a double inverted pendulum (DIP) suggested in addition a biomechanical damping effective from trunk sway in the hip joints on the resonance.

description: Given a multi-agent linear system, we formalize and solve a trajectory optimization problem that encapsulates trajectory tracking, distance-based formation control and input energy minimization. To this end, a numerical projection operator Newton's method is developed to find a solution by the minimization of a cost functional able to capture all these different tasks. To stabilize the formation, a particular potential function has been designed, allowing to obtain specified geometrical configurations while the barycenter position and velocity of the system follows a desired trajectory.

Medieval seamanship under sail

Publisher: name: University of British Columbia
Year: 2010

description: Voyages of discovery could not be entertained until the advent of three-masted ships. Single-sailed ships were effective for voyages of short duration, undertaken with favourable winds. Ships with two masts could make long coastal voyages in the summer. Both these types had more or less severe limitations to sailing to windward. To sail any ship successfully in this mode it is necessary to be able to balance the sail plan accurately. This method of keeping course could not reach its full development until more than two sails were available for manipulation. Rudders never were adequate to hold ships to windward courses. Ships with three or more masts could be sailed in all weather with very little dependence on the power of the rudder and the freedom from this limitation made it possible to build ships large enough to carry sizable crews, their stores and spare gear over ocean crossings.
The Structural Parameters of Bulges, Bars and Discs in the Local Universe

Subjects: subject: Astrophysics (astro-ph)

description: Image decomposition of galaxies is now routinely used to estimate the structural parameters of galactic components. In this work, I address questions on the reliability of this technique. In particular, do bars and AGN need to be taken into account to obtain the structural parameters of bulges and discs? And to what extent can we trust image decomposition when the physical spatial resolution is relatively poor? With this aim, I performed multi-component (bar/bulge/disc/AGN) image decomposition of a sample of very nearby galaxies and their artificially redshifted images, and verified the effects of removing the bar and AGN components from the models. Neglecting bars can result in a overestimation of the bulge-to-total luminosity ratio of a factor of two, even if the resolution is low. Similar effects result when bright AGN are not considered in the models, but only when the resolution is high. I also show that the structural parameters of more distant galaxies can in general be reliably retrieved, at least up to the point where the physical spatial resolution is about 1.5 Kpc, but bulge parameters are prone to errors if its effective radius is small compared to the seeing radius, and might suffer from systematic effects. I briefly discuss the consequences of these results to our knowledge of the stellar mass budget in the local universe, and finish by showing preliminary results from a large SDSS sample on the dichotomy between classical and pseudo-bulges.

description: The main concern of today’s agriculture is increasing crop productivity to feed the huge population of India. Crop yield is often affected by some biotic and abiotic factors, like climatic factors, agronomic factors, pests, nutrient availability of soil, etc. Stress is addressed as any adverse environmental condition that hampers plant growth. From the last few decades, nanobiotechnology-based applications to mitigate stress attracted researchers' attention in this direction. Here, we have reviewed and discussed the enhancement of productivity in cereals, pulses, oilseeds, and fibre crops mitigating drought stress through the application of optimum concentration of nanoparticles (NPs).

description: We discuss a novel strategy to construct 4D N=0 stable flux vacua of type II string theory, based on the existence of BPS bounds for probe D-branes in some of these backgrounds. In particular, we consider compactifications where D-branes filling the 4D space-time obey the same BPS bound as they would in an N=1 compactification, while other D-branes, like those appearing as domain walls from the 4D perspective, can no longer be BPS. We construct a subfamily of such backgrounds giving rise to 4D N=0 Minkowski no-scale vacua, generalizing the well-known case of type IIB on a warped Calabi-Yau. We provide several explicit examples of these constructions, and compute quantities of phenomenological interest like flux-induced soft terms on D-branes. Our results have a natural, simple description in the language of Generalized Complex Geometry, and in particular in terms of D-brane generalized calibrations. Finally, we extend the integrability theorems for 10D supersymmetric type II backgrounds to the N=0 case and use the results to construct a new class of N=0 AdS4 compactifications.

description: The recent rediscovery of magnetic field switchbacks or deflections embedded in the solar wind flow by the Parker Solar Probe mission lead to a huge interest in the modelling of the formation mechanisms and origin of these switchbacks. Several scenarios for their generation were put forth, ranging from lower solar atmospheric origins by reconnection, to being a manifestation of turbulence in the solar wind, and so on. Here we study some potential formation mechanisms of magnetic switchbacks in the lower solar atmosphere, using three-dimensional magneto-hydrodynamic (MHD) numerical simulations. The model is that of an intense flux tube in an open magnetic field region, aiming to represent a magnetic bright point opening up to an open coronal magnetic field structure, e.g. a coronal hole. The model is driven with different plasma flows in the photosphere, such as a fast up-shooting jet, as well as shearing flows generated by vortex motions or torsional oscillations. In all scenarios considered, we witness the formation of magnetic switchbacks in regions corresponding to chromospheric heights. Therefore, photospheric plasma flows around the foot-points of intense flux tubes appear to be suitable drivers for the formation of magnetic switchbacks in the lower solar atmosphere. Nevertheless, these switchbacks do not appear to be able to enter the coronal heights of the simulation in the present model. In conclusion, based on the presented simulations, switchbacks measured in the solar wind are unlikely to originate from photospheric or chromospheric dynamics.

R&D accounting discretion as an income smoothing tool: An empirical analysis of German listed companies
Creators: name: Brettschneider, Carina
Publisher: name: Junior Management Science
Year: 2019

description: Capitalization of development costs is compulsory according to IFRS if a set of criteria is fulfilled. However, this obligation is considered as a de facto right for capitalization since the criteria are quite subjective, allowing for a certain degree of flexibility. Hence, the question arises whether managers use research and development (R&D) accounting to conduct earnings management in terms of income smoothing. Using a sample of German listed companies, the study conducts several regression analyses to test whether there is a negative relationship between R&D capitalization and different income smoothing proxies. Results show that the hypothesis is supported independent of the income smoothing proxy used. The study proofs that managers indeed use R&D capitalization judgments to conduct income smoothing.

description: An extended Designed regression analysis of experimental data on density and refractive indices of several classes of ionic liquids yielded statistically averaged atomic volumes and polarizabilities of the constituting atoms. These values can be used to predict the molecular volume and polarizability of an unknown ionic liquid as well as its mass density and refractive index. Our approach does not need information on the molecular structure of the ionic liquid, but it turned out that the discrimination of the hybridization state of the carbons improved the overall result. Our results are not only compared to experimental data but also to quantum-chemical calculations. Furthermore, fractional charges of ionic liquid ions and their relation to polarizability are discussed.
Radiative Hydrodynamical Studies of Irradiated Atmospheres

description: Transiting planets provide a unique opportunity to study the atmospheres of extra-solar planets. Radiative hydrodynamical models of the atmosphere provide a crucial link between the physical characteristics of the atmosphere and the observed properties. Here I present results from 3D simulations which solve the full Navier-Stokes equations coupled to a flux-limited diffusion treatment of radiation transfer for planets with 1, 3, and 7 day periods. Variations in opacity amongst models leads to a variation in the temperature differential across the planet, while atmospheric dynamics becomes much more variable at longer orbital periods. I also present 3D radiative simulations illustrating the importance of distinguishing between optical and infrared opacities.

Implementation of strategic change by franchisees: A sensemaking perspective
Creators: name: Langenmayr, Theresa
Publisher: name: Junior Management Science
Year: 2019

description: Franchisees play an important role when inter-organizational change, initiated by franchisors, is to be implemented. The objective of this thesis is to gain insights into franchisees’ sensemaking activities. Drawing on sensemaking theories and franchising literature, a case study on franchisees in the automotive industry reveals how social processes of interaction, within and across their organizational boundaries, influence their interpretations of change initiatives. It contributes to the sensemaking literature through expanding research to inter-organizational change. It also contributes to the franchising literature through analyzing the franchisees’ role during franchisor-initiated change from a sensemaking perspective.

description: For a multi-agent system state estimation resting upon noisy measurements constitutes a problem related to several application scenarios. Adopting the standard least-squares approach, in this work we derive both the (centralized) analytic solution to this issue and two distributed iterative schemes, which allow to establish a connection between the convergence behavior of consensus algorithm toward the optimal estimate and the theory of the stochastic matrices that describe the network system dynamics. This study on the one hand highlights the role of the topological links that define the neighborhood of agent nodes, while on the other allows to optimize the convergence rate by easy parameter tuning. The theoretical findings are validated considering different network topologies by means of numerical simulations.

При проведении анализа трансформации концепции экономического роста в концепцию устойчивого развития особое внимание уделено экономическому аспекту. Рассмотрена в ретроспективе и систематизирована информация о состоявшихся конференциях, саммитах, опубликованных работах, программах, конвенциях, законах, а также институтах, занимающихся вопросами устойчивого развития. Подробно освещены концепции нулевого и органического роста. Сделаны выводы о возможных направлениях развития концепции «зеленой» экономики.
description: The article presents a historical background for the development of the concept of sustainable development. The key aspects that form the concept are considered: ecological, social, and economic. Due to the analysis of the transformation of the concept of economic growth into the concept of sustainable development, special attention is paid to the economic aspect. Conferences, summits, works, programs, conventions, and laws, as well as institutions dealing with sustainable development, are systematized. Two main concepts that are zero growth and organic growth are highlighted in detail. Conclusions about the possible directions for the development of the concept of “green” economy are made.
Spatial and Temporal Patterns of Dissolved Carbon in a North Pacific Coastal Temperate Rainforest Stream

description: The coastal temperate rainforests of Southeast Alaska are terrestrial-aquatic interfaces that mediate the transfer of vast quantities of water and materials from land to sea, largely through thousands of streams draining small, steeply sloping watersheds. Stream export processes are an important part of the coastal temperate rainforest carbon cycle, including supporting carbon sequestration through enhanced nearshore productivity and sedimentation, and may play a role in regulating future carbon-climate feedbacks. Yet, the ecohydrological mechanisms that regulate stream export of carbon, and would mediate any future climate feedback, are less well understood at the sub-watershed spatial scale and at sub-seasonal temporal scales. In this study, we quantified continuous, high-frequency dissolved organic carbon flux and methane concentrations in Peterson Creek, near Juneau, AK, during the peak growing season (June-August 2023). We explored how three antecedent meteorological states (dry, drought, rainy) affected three regionally representative hydropedological units (upland forest, forested wetland, and poor fen) to contribute to the Peterson Creek carbon export dynamics, using continuous water table depth and discharge, and discrete dissolved organic carbon and methane measurements in the soils and connecting tributaries of each unit. We found that methane was typically a very small component (<1%) of total dissolved organic carbon, but that exceptionally high concentrations could occur under a drought-to-rain sequence and that the source appears to be the poor fen. Our study therefore builds on previous work demonstrating the importance of lateral flushing of carbon out of coastal temperate rainforests during rain events by showing that this same general mechanism is applicable to methane during rarer drought-to-rain sequences.
The Influence of Cryptocurrencies on Enterprise Risk Management – an Empirical Evidence by the Example of Bitcoin
Creators: name: Bölstler, Maximilian
Publisher: name: Junior Management Science
Year: 2019

description: This thesis analyzes the influence of cryptocurrencies in the context of risk management by considering the emerging risk factors of Bitcoin as a payment method. By means of an empirical analysis through an online survey, the current operational dealing of incoming Bitcoin funds, the risk awareness of the potential threats, and the corresponding control activities implemented by companies accepting Bitcoin payments have been examined. The results reveal that the risks of this new technology-based payment method have not been extensively evaluated and that there exists a partially significant lack of know-how. Therefore, the risks are either not at all or improperly addressed by a majority of the organizations. However, the exchange rate risk and the cyber risk, which is a strongly linked to the administration of cryptocurrencies, represent the most significant related risk factors associated with cryptocurrencies in recent times. To ensure an appropriate operational dealing with cryptocurrencies, the author presents a risk control matrix based on the results of the analysis and discusses control activities to mitigate these emerging threats. Finally, a holistic Cryptocurrency IC Framework (following the COSO 2013 IC Framework) is presented, with the objective of effectively and efficiently developing and maintaining systems of internal control with regard to cryptocurrencies.

Arabic music and the piano: the use of the piano in Lebanon and Egypt during the golden age of Arabic music
Creators: name: Molina, Patricio Fadel
Publisher: name: No Publisher Supplied
Year: 2021

description: During the 1930s, Egyptian and Lebanese composers began to incorporate the piano into their works. Because the piano also brought equal temperament, which is distinctly different than the tuning system used in Arab folk music, this new instrumental combination made a deep impact on the musical structure itself. The story of how the piano was introduced to the Arab World, however, is not well known.In this dissertation, I discuss the introduction of the piano (and consequently of equal temperament) into Egyptian and Lebanese Arabic music of the 1930s–60s. I also compare Western and Arabic music theory and explore how the piano influenced the composition of Arabic music. The study is in two parts: 1) an analysis of Egyptian and Lebanese music from 1930–60 that features the piano alongside traditional Arabic instrumentalists and vocalists, and 2) a biographical study of musicians that brought Western elements into Arabic music.The fusion techniques developed during the period 1930–60 continue to inform compositions created by Arab musicians in the United States and elsewhere. In the fourth chapter, I provide an overview of Arabic music in the United States in the 21st century.My research concludes with an original composition entitled Memories of Homs, for Arabic ensemble and piano. The last chapter is an analysis of this work. This topic is especially meaningful for two reasons: the piano is a dominant element in my musical career, and my Syrian heritage continues to shape my overall musical experience.
