Major focus is on the ideological background of the conquest with elaborations on Iberian philosophies held by conquistadors. Equally important are evaluations of Indian religion and social customs based on such sources as Aristotelian and Thomist doctrines as understood by Spanish writers. Political organization and the hierarchy of rul… more

Life History Biology of the Desert Nesting Seagull Larus modestus

Description: Gray gulls Larus modestus are unique among birds of northern Chile as the only species nesting in the interior Atacama Desert, and the only seagull nesting far (30 - 100 km) from surface water. During breeding-nesting (August - February) gray gulls congregate on the coast of northern Chile where they feed and initiate courtship. As early as August, breeding pairs commute daily to the inner desert to establish nesting territories, round-trip distances of 60-200 Km. During incubation (30 days) an… more

Modeling State Repression in Argentina and Chile: A Time Series Analysis

Description: This study is an attempt to contribute to the emerging theoretical literature on state repression. A time-series model was developed to test the hypothesis that state violence in Argentina and Chile is largely a function of four internal political factors and their interactions: 1) the inertial influence of past restrictive policies on the formulation of current policies, 2) the annual incidence of political protest demonstrations, 3) the perceived effectiveness of repressive measures on unrest… more

Niche Structure of an Anole Community in a Tropical Rain Forest within the Choco Region of Colombia

Description: Ten species of anoles at Bajo Calima within the Choco of Western Colombia separate into two principal microhabitat groups: forest species, and those inhabiting openings and edges. The ten anoles further separate according to ground and vegetation dwellers. There is a relation at Bajo Calima between the number of anole species and vegetational structural diversity. Anole diversity within a given macrohabitat is by perch microsite/microclimate heterogeneity. These are the two major ecological dim… more

Perón of Argentina: Case Study in Political Charismatic Leadership

Description: The thesis here is that the Argentina of the 1940's provided a perfect matrix for the rise of a charismatic leader. Juan Perón did not emerge as an European-style fascist or the traditional Latin American dictator. Rather, he was called forth by his environment to exercise authority over his followers in a leader-mass, savior-disciple relationship. Perón's base environment was Argentine. Thus, Argentine patterns, values, and culture outlined the scope and methods of his rule. For this reason th… more

La Poesía Lírica Colombiana

Description: In this work, superficial to the extreme, it is my purpose to offer a review of the development of lyric poetry ("poesía lírica") in Colombia throughout its history. It is logical that because of the extent of the subject it is not possible to give a complete treatment of our political history, though I have tried not to leave out points of significance. The classification of authors and of poems, as well as the division of periods I have made arbitrarily, guided by my own criteria. Thus, I hav… more

Re-Assessing Nationalism in the Art Songs of Jaime León

Description: 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 … more

The Brazilian Art Song and the Non-Brazilian Portuguese Singer: A Performance Guide to Nine Songs by Alberto Nepomuceno

Description: Alberto Nepomuceno (1864-1920) is considered to be the father of the Brazilian art song. With a total of seventy songs, Nepomuceno revolutionized and established a new path to the Brazilian art song. His songs were innovative because they: (1) incorporated folk elements in his songs, (2) introduced Portuguese as a language acceptable in bel canto style and (3) established Brazilian songs in the tradition of the European vanguard. His approach influenced several composers including his young stu… more

A National Idiom Universally Understood: Brazilian Tradition and Personal Evolution in Osvaldo Lacerda's "Variações e Fuga para quinteto de sopros"

Description: The career of Osvaldo Lacerda (1927-2011) spanned a critical time in the development of Brazilian nationalist music. Though he was an outspoken nationalist composer, he was also influenced by European trends and training. Even within his nationalist compositions, evidence of a shift in style that mirrors the European movements of Modernism and Postmodernism is found in his works. Among his thirty-six chamber works, three are wind quintets, written between 1962 and 1997. Although all three works… more

Two Argentine Song Sets: A Comparison of Songs by De Rogatis and Ginastera

Description: Latin American classical vocal repertoire is vast, but in the United States, we only hear a fairly limited part of this literature. Much of this repertoire blends western European classical music traditions and native folk music traditions. One example of such a Latin American vocal work that is well-known in the United States is Alberto Ginastera's frequently performed song set from 1943, Cinco canciones populares argentinas. However, another lesser-known, earlier work, Cinco canciones argenti… more

Niche Expansion of an Invasive Predator (Neovison vison), Prey Response, and Facilitative Interactions with Other Invasive Mammals at the Southern End of the Americas: Conservation Challenges and Potential Solutions

Description: The Cape Horn Biosphere Reserve is located at the southern tip of South America. This large archipelago is considered one of the last pristine areas left on the world. Despite it being an unpopulated area with most of the native forest cover intact, it has not been exempt from biological invasions, one of the major drivers of biodiversity loss. Three species that naturally interact in their native range in North America – American beavers (Castor canadensis), muskrats (Ondatra zibethicus), and … more

Leveraging Virtual Communities of Practice to Analyze Well-Being among Female Brazilian Jiu-jitsu Practitioners

Description: The purpose of this dissertation is to examine the impact of being a member of a women’s virtual community of practice in the niche martial art of Brazilian jiu-jitsu (BJJ) on perceptions of well-being. Women’s well-being has yet to be explored in the context of a combat sport such as BJJ. Due to geographic isolation and women as a minority in the world of BJJ, many females turn to joining virtual communities of practice to find connection, exchange ideas, knowledge, and resources, and to have … more
