Alberto Grau is arguably one of the most influential contemporary Venezuelan choral composers and conductors of the twentieth and twenty-first centuries. This thesis explores the synthesis of Venezuelan nationalism with global internationalism found within his works. As a student of the nationalistic generation of composers (Vicente Emilio Sojo, Juan Bautista Plaza, and Ángel Sauce) Grau's works display the distinct characteristics found in Venezuelan music. His output also exhibits international influences, using texts associated with social and environmental events and concerns including literary and musical influences of other nations and cultures. The first section of the thesis traces the lineage of Venezuelan choral composers beginning with the colonial period and the Escuela de Chacao to the nationalistic composers from the Santa Capilla generation. The second section describes Alberto Grau's compositional style as exemplified in his work Kasar mie la gaji (The Earth is Tired). The final section of the document comprises interviews with Alberto Grau and his wife, the Venezuelan choral conductor, María Guinand. Guinand studied piano and conducting with Alberto Grau and was his assistant at the Orfeón Universitario Simón Bolívar and the Schola Cantorum de Caracas. She is the founding conductor of the Cantoría Alberto Grau and the editor …

Light spectra distributions were measured in two different montane forests: temperate and tropical. Spectral light measurements were made in different sized canopy gaps in the conifer forest at H. J. Andrews Experimental Forest in Oregon, USA. Researchers at Oregon State University created these gaps of 20 m, 30 m, and 50 m in diameter. In the tropical cloud forest, spectral light measurements were made in two plots that were permanently established at La Mucuy Parque Nacional in Venezuela, in collaboration with researchers at Universidad de Los Andes. In both studies, spectra and distributions of physiologically active light were analyzed: red, far-red, R/FR ratio, and blue light.

Managing water quality aspects requires the use of integrative tools that allow a holistic approach to this problem. Water quality models coupled to hydrodynamic models are these tools. This study presents the application of the water quality model WASP coupled to the hydrodynamic model DYNHYD for two distinct reservoirs: Lake Texoma and Tocoma Reservoir. Modeling the former included simulations of water velocities, water level, and four chemical and physical compounds: chlorides, dissolved oxygen (DO), biochemical oxygen demand (BOD), and total suspended solids (TSS); and validation of the results by comparing with observed values during March - May, 1997. The latter is still under project status and the simulation was performed in a prospective way. The analysis included simulations of water velocities under current and for expected conditions, DO and BOD. Both models, DYNHYD and WASP, fitted pretty well to observed conditions for Lake Texoma and for where Tocoma Reservoir has been planned. Considering management and decision support purposes, the role of boundary and loading conditions also was tested. For Lake Texoma, controlling boundary conditions for chlorides is a determinant factor for water quality of the system. However, DO and TSS in the reservoir are governed by additional process besides the …

President Franklin D. Roosevelt and Undersecretary of State Sumner Welles began trying to make military matériel available to Latin America during the latter 1930s. Little progress was made until passage of the Lend-Lease Act in 1941 enabled Washington to furnish eighteen Latin American nations with about $493,000,000 worth of military assistance during World War II. This study, based primarily on State Department lend-lease decimal files in the National Archives and documents published in Foreign Relations volumes, views the policy's background, development, and implementation in each recipient nation. The conclusion is that the policy produced mixed results for the United States and Latin America.

Latin American art song is a genre primarily of the first half of the twentieth-century, when popular folklore served as the voice and inspiration of many poets and musicians. The nationalist movement served as a means of expression, each Latin American country with its own identity. There is great benefit for singers to study Spanish diction at an academic level, since it is a language already familiar to most U.S.A residents. There is a significant amount of unknown repertoire that would be very useful in the singing studio because of the language's open vowels. This repertoire can also serve as a confidence-builder to young Spanish-speaking singers at the beginning of their training. I will be focusing on the (s), (ll), and (y) sounds as pronounced in the diverse regions of Latin America; in particular, why they matter when coaching singers, and the articulators involved in each. The purpose of this study is to discuss diction differences in the repertoire, expound on its benefits for voice pedagogy, all while informing about varied options for recital programming.

News media consumption is vital to understanding democracy in Latin America. Democracy in the region lacks consolidation that may be encouraged by the ability of news media to shape individuals' political attitudes and behaviors. Yet, we know very little about how citizens of Latin American countries consume news media or how that consumption affects attitudes and behavior. This study offers a region-wide examination of the factors that shape news media consumption and the effects of that consumption on individuals in the region. To explore this topic, I examine survey data from the 2008 Latin American Public Opinion Project in 18 Latin American countries. I argue that news media promote democratic attitudes and political behavior by increasing the symbolic value of democracy and by supplementing those symbols with information that further encourages democratic attitudes and political participation. Additionally, political behavior is not temporally proximate to political behaviors such as voting. This necessitates a mediated path for news media consumption to influence participation through political interest, civil society participation and democratic attitudes. My findings illustrate that each news medium type (TV, radio, newspaper) must be considered separately from each other type. I find that news media consumption has little effect on attitudes. …

This dissertation investigates three questions: First, what conditions make dissident collective action such as protest, revolt, rebellion, or civil war more likely to happen in a country? Second, what conditions make citizens more likely to join in dissident collective action? Third, does Internet use play a role in dissident collective action, and if so, why? I argue that motives and resources are necessary rather than sufficient conditions for dissident collective action. I develop an analytical framework integrating motives and resources. Specifically, I theorize that state repression is an important motive, and that civil society is critical in providing resources. Four statistical analyses are conducted to test the hypotheses. Using aggregate level data on countries over time, I find that civil war is more likely to occur in countries where both state repression and civil society are strong. Moreover, the effect of civil society on civil war onset increases as the repression level rises. at the individual level using 2008 Latin American Public Opinion Project surveys from 23 Latin American and Caribbean countries, I find individuals more likely to join in protest when they experience both more repression and greater civic engagement. Moreover, civic engagement’s effect on protest participation increases as …

Innovations as a source of economic wellbeing and social prosperity has been well researched, albeit primarily done in the context of developed economies. However, of late, interest in the effect of innovation on economic performance and quality of life has been renewed as the world observes the rise of emerging economies, and at the same time, the prolonged recession in the more developed economies (i.e. North America and European countries). There has been a marked increase in the quantity and quality of research and development, spawn by innovative companies from emerging economies that are making their mark in global marketplace. These phenomena challenge the traditional concept that innovation flows from the resource rich developed countries to less developed countries, and that the latter are at a disadvantage in terms of knowledge, technology and competitiveness. Existing studies on national innovation highlight the relationships between innovative capability and its outcomes; however, few have tried to explain the determinants of a nation’s innovative capabilities. Using a sample of 95 countries and panel data analysis covering 28 years of observation, this study attempts to model the determinants of innovative capability at national level, and focuses on absorptive capacity and institutional framework as the main …

The focus of the study is on financial reporting for non-U.S. firms registered with the Securities Exchange Commission (SEC) but using International Accounting Standards (IAS). This study addresses two issues, (1) whether the comparability of financial reporting among firms using IAS in credit and equity financing jurisdictions increases over time and (2) the associated capital market implications. The motivation for the study is the SEC's ongoing assessment of IAS for possible use by non-U.S. registrants for listing and capital raising in the U.S. Previous research on variations in financial reporting practices has revealed distinctly different types of financial reporting depending on country of origin. Moreover, some research suggests that such differences in financial reporting tend to persist in spite of harmonization efforts of accounting standards. This study suggests that there may be a systematic difference between credit and equity firms' financial reporting that is manifested by the fact that credit firms' adjustments to U.S. GAAP are greater than the adjustments made by equity firms. This systematic difference has had the following capital market consequences for credit firms, (1) a decreasing strength of association between accounting earnings and share prices post-1994, (2) an increased bid-ask spread post-1994, and (3) a decreased …

This study explores the relationship between economic development, social mobility, elites, and regime formation. I argue that the genesis of regime formation, in general, and of democratic regimes, in particular, is determined by the type of economic structure a society possesses, on the one hand, and on the degree the to which demands from disfranchised groups do or do not pose a substantial threat to the interests of elites who occupy the upper strata of the social and economic status hierarchy. Second I demonstrate that the dynamics of transition to wider political participation, as the core element of a democratic system of governance, and the survival of such change are different. In what follows I illustrate that some factors that have been found to dampen the chances for wider participation or have been found to be unrelated to onset of a democratic system of governance have considerable impacts on the durability of the democratic regimes. In a nutshell, the analysis points to the positive effects of mineral wealth and income inequality on the prospects of a democratic survival. Using a cross-national time series data set for all countries for the period between 1960 and 1999 I put the hypotheses to …

Why does civil conflict spread from country to country? Existing research relies primarily on explanations of rebel mobilization tied to geographic proximity to explain this phenomenon. However, this approach is unable to explain why civil conflict appears to spread across great geographic distances, and also neglects the government’s role in conflict. To explain this phenomenon, this dissertation formulates an informational theory in which individuals contemplating rebellion against their government, or “proto-rebels,” observe the success and failure of rebels throughout the international system. In doing so, proto-rebels and governments learn whether rebellion will be fruitful, which is then manifested in the timing of rebellion and repression. The core of the dissertation is composed of three essays. The first exhorts scholars of the international spread of civil violence to directly measure proto-rebel mobilization. I show that such mobilization is associated with conflicts across the entire international system, while the escalation to actual armed conflict is associated with regional conflicts. The second chapter theorizes that proto-rebels learn from successful rebellions across the international system. This relationship applies globally, although it is attenuated by cultural and regime-type similarity. Finally, the third chapter theorizes that governments are aware of this process and engage in repression …

The purpose of this study is to explore the representation of national political freedom on web interface design by using power distance, one of the culture dimensions identified by Geert Hofstede, as a measurement. This study also aims to determine if there are any differences between government-based websites and business-oriented websites in representing national political freedom. A pilot study was conducted to validate ten power distance indicators identified from previous research on cultural dimensions with the intent of establishing a measurement for determining a country's national political freedom on web content and interface design. The result showed that six out of ten proposed indicators are valid power distance indicators. The seventh indicator, symmetric layout, demonstrated that its Web representation correlates with national political freedom level. Consequently, the principal research applied these seven indicators in coding 312 websites selected from 39 countries and analyzed national political freedom represented on these websites with content analysis method. The result of two-way analysis of variance (ANOVA) indicated that large differences exist in web interface design, which in turn reflects the aforementioned national political freedom. The research showed that the mean effect of freedom level between free-country group, partly-free-country group and not-free-country group was statistically …

The small businessman in an undeveloped country often finds himself isolated from formal, institutional credit sources, either through ignorance or by his non-acceptability as a credit risk. Both his lack of credit and lack of education can limit his participation in national development, and in fact, such development might even work against him as it makes his competitors' easier access to these resources even more important. It was concluded that the educational level achieved by the small businessman in Santos Guardiola is roughly the sixth grade, that the lack of business and financial content in their formal education does not prevent their learning about business and finance, and that a large majority of them use credit in their business. It was further concluded that the loan officers with the four lending institutions have adequate education and training to administer the loans made, that business credit needs are generally satisfied without resort to an informal credit market, and that while the deposits and business loans are expanding for all four institutions the credit union has been able to expand most rapidly by attracting the small saver and the small borrower. In addition, it was concluded that development banks are primarily interested …

Colombian composer Jaime León (1921-2015) is known for his art songs. Most of the current scholarly literature about León defines him as a nationalist composer even though a majority of his songs do not appear to have nationalist traits. This document examines a representative selection of León's songs divided into three categories: songs influenced by the bambuco (the Colombian genre most present in his songs); songs whose text refers to Colombian culture; and songs without Colombian elements present in their text or music. After examination of these songs, my conclusion is that León, rather than being nationalist, was a cosmopolitan composer who used national elements as rhetorical tools in an isolated and experimental way.

A large portion of the standard repertoire for saxophone and piano has already been recorded and performed many times and has received significant scholarly study. For a performer, remaining relevant requires learning and performing new compositions. Jorge Sosa and Andrés Alén are both accomplished composers, yet outside of the Latin-American community they remain virtually unknown to most saxophonists. This project serves as an introduction to both composers. Combined, Sosa and Alén have nine compositions for saxophone. Their works include saxophone quartets, saxophone and piano, and saxophone quartet with choir. This study focuses on three compositions: La Zacapaneca by Sosa, Tema con Variaciones and Sonata para Clarinete ó Saxofón Soprano y Piano, both by Alén. Compositional background information is given about each composition to include date of composition, premiers, important recordings, length of performance and Cuban ethnic and traditional elements used as the basis for rhythmic and thematic ideas. The Cuban and Afro-Cuban influences are explained in further detail pertaining to how they were used in the construction of the works and in their being performed stylistically correctly. Dynamics, articulations, and performance considerations are studied at length.

Since the 1970s, a curious phenomenon has emerged, suggesting that resource rich countries are "cursed" by their resources. Over the last couple of decades, researchers have argued that rentier countries are more likely to have educational underachievement, the Dutch disease, corruption, slower democratization, and conflict. Although current research has proven helpful and productive, some aspects still remain contested in both theoretical and empirical terms. This dissertation aims to fill certain lacunae in this literature. My dissertation examines how ordinary citizens turn into dissidents and then to rebels in rentier states. I build and test an innovative theoretical argument, which focuses on individuals' daily lives, and explains how policies by rentier governments discourage merit-based employment. This, in turn, yields a high level of grievance among segments of the population. I also develop a comprehensive theory that combines macro-level and micro-level explanations of conflict onset in rentier states. Finally, I analyze an important, but previously neglected aspect of civil wars in rentier states: conflict outcomes. I suggest that the existence of abundant natural resources would have a significant impact on conflict outcomes. Accordingly, government victory would be more likely, and negotiated settlement would be less likely in rentier countries compared to non-rentier …

The goals of this study were to use Geographic Information Systems (GIS) and remote sensing technologies to gain a better understanding of habitat requirements of a population of ocelots in south Texas, and then apply this knowledge to form a predictive model to locate areas of suitable habitat in Willacy and Cameron counties, Texas. Satellite imagery from August 1991 and August 2000 were classified into four land cover types: closed canopy, open canopy, water, and urban/barren. These classified images were converted into digital thematic maps for use in resource utilization studies and modeling. Location estimates (762 from 1991 and 406 from 2000) were entered into a GIS in order to extract information about home range and resource selection. Each animal's home range was calculated using both Minimum Convex Polygon (MCP) and Kernel home range estimators (95% and 50%). Habitat parameters of interest were: soil, land cover, human density, road density, and distance to closest road, city and water body. Ocelots were found to prefer closed canopy and avoid open canopy land cover types. Ocelots preferred soils known to support thorn scrub, an indication of the importance of this habitat. Landscape metrics associated with habitat used by ocelots were determined through …

This study emphasizes the impact of family planning program components on contraceptive prevalence in less industrialized countries. Building on Lapham and Mauldin's "Program Effort and Fertility Decline" framework and policy evaluation's theory, the author developed two models to examine the impact of family planning programs on contraceptive prevalence and fertility under the constraints of socioeconomic development and demand for family planning. The study employed path analysis and multiple regression on data from the 1982 program effort study in 94 less developed countries (LDCs) by Lapham and Mauldin and 98 LDCs of the 1989 program effort study by Mauldin and Ross. The results of data analyses for all data sets are consistent for the most part. Major findings are as follows: (1) A combination of program effort and socioeconomic development best explains the variation of contraceptive prevalence. (2) Among socioeconomic variables, female literacy exerts the strongest direct and indirect influences to increase contraceptive prevalence and indirect influence to decrease total fertility rate. (3) Christianity performs a significant role in reducing contraceptive prevalence. (4) Among program effort components, availability and accessibility for fertility-control supplies and services have the most influence on contraceptive prevalence. (5) When controlling for demand for family planning, female …

Spanish settlers brought the precursor to the bassoon, el bajón, to Mexico in the late sixteenth century. Documentation of the bassoon was intermittently from the sixteenth century on, the current playing traditions were not established until the second half of the twentieth century. Bassoon education in Mexico flourished in the 1970's because several bassoonists became expatriates, and chose to live and work in Mexico for the entirety of their careers. Two major pedagogues, Lazar Stoychev and Jerzy Lemiszka paved the way for the current Mexican bassoon community. This dissertation presents a selective lineage of bassoonists who have held positions in major Mexican orchestras and universities since the mid-twentieth century. The purpose of this study is to recognize the contributions these players and teachers have given to the bassoon world. In recent years, Mexican bassoonists have commissioned hundreds of works for the bassoon and this significant achievement has placed the Mexican bassoon community in an upward trajectory. To place these players in proper historical context, a brief history of classical music institutions in Mexico since the sixteenth century is given. This dissertation documents the history and pedagogy of recent bassoonists in Mexico via a cohesive family tree.

The purposes of this study were to examine the problems of international students, assess the intensity of these problems, and describe relationships between the intensity of the problems and the following demographic variables: age, gender, number of years in the study of English, number of years living in the United States, grade point average at North Texas State University, major area of study at North Texas State University, and country of origin. International students pragmatically view their sojourn in the United States as an educational experience that will allow them to improve their minds and to travel. Financial concerns were expressed by the desire to work either part time or during vacation periods. As a group, international students do not exhibit concerns which debilitate their movement toward established goals. However, there are individual students who are in need of cultural refraining, communication abilities, and coping skills.

Scholars generally assume that states are shamed for their own behavior, but they can also be shamed for the lack of investigation for violence perpetrated by domestic non-state actors. I engage this previously-unstudied phenomenon and develop a theory to explain how states will respond to being shamed for failing to control domestic violence. I examine two types of outcomes: the governments' change in behavior, and the accountability efforts against state agents that have abused human rights. For the government's reaction to being shamed for violence from non-state organizations, I develop a theory to examine changes in coercive state capacity – including military and police personnel – since this reaction may largely exacerbate human rights violations. I hypothesize that states shamed due to abuses by violent non-state organizations (VNSO) will increase military personnel to halt criminal violence and respond to the international spotlight. I then examine the relationship between naming and shaming states over physical integrity abuses by different types of perpetrators and human rights prosecutions. Using newly coded data on the types of perpetrators shamed in the United Nations Human Rights Council (UNHRC) country reports, I find that shaming over abuses that include VNSO as perpetrators decreases the likelihood of …

Cutaneous leishmaniasis (CL) is usually a self-limiting lesion on the skin while visceral leishmaniasis is a progressive, systemic disease with high mortality even if treated. The problem associated with treatment and vector control justifies a search for an effective vaccine which seems to be the only practical means to control the disease. The aim of this study is to identify immunological surrogate marker(s) associated with protection against Leishmania infection. The results indicate that a single dose of ALM+BCG induced Thl-like response but the level of such response is not sufficient for full protection. Accordingly, further evaluation of the vaccine is necessary other strategies multiple injections or changing the adjutant.

The purpose of this study is three-fold. The first is to provide the reader with a review of the literature concerning the topic of regional political integration. The second purpose is to provide an operational definition of regional political integration which can be useful in the testing of hypotheses. Regional political integration is defined in terms of the regional decision-making process. Various levels of regional political integration are defined, operationalized, and identified. The levels from lowest to highest are as follows: regional promotion, regional information exchange, regional policy coordination, regional monitor, and regional authoritative decision-making. The third purpose of the study is to analyze the factors which are hypothesized to be correlated with and responsible for the changing levels of regional political integration.

Research on ethnicity and conflict treats the concept of ethnicity as defining the actors in these conflicts, whereas research on the construction and maintenance of ethnic identity explores why ethnicity unifies individuals into a single social group. What happens when this unifying concept is divided between two enemy countries? How does this situation influence peace settlements over territorial issues, armed conflict, and economic relations between these countries? To answer these questions, I create a continuous measure of ethnic similarity between rivals. I find that ethnic similarity can facilitate cooperation and exacerbate conflictual interactions between rivals, but governments will seek to limit interactions with their rival when the cross border ethnic groups are minorities. In addition, I create categorical predictors of ethnic similarity, which reveal nuances in these relationships. Specifically, rivalries sharing a pan-ethnic identity are more likely to engage in conflict regardless of actual ethnic similarity, and dyads with a majority in one country sharing ethnicity with a minority in another country are less likely to fight once in a state of rivalry. This is because a quid pro quo exists between these rivals where one rival can reduce oppression of the minority in exchange for the other rival not …
