    LA FIESTA DEL ESPIRITU SANTO: AN ORIGINAL WORK FOR CHOIR, SOLOISTS, AND SMALL ENSEMBLE INFLUENCED BY THE SANTERIA MUSIC OF THE AFRICAN-DOMINICAN COMMUNITY IN THE DOMINICAN REPUBLIC

    Get PDF
    ABSTRACT This study examines the role of Santería music as practiced by African Dominicans in Villa Mella, a neighborhood of Santo Domingo, Dominican Republic. This musical tradition comes from the culture and religion of the Yoruba people who were brought as slaves from Africa, and features complex drum rhythms and call-and-response chants. This paper deals with the historical and social context of Santería music within the Dominican Republic, but its principal objective is to adopt the musical language of this tradition and use it to create a new contemporary work for mixed choir and small ensemble. One of the most influential musical groups for this thesis was La Cofradía de los Congos del Espíritu Santo de Villa Mella, because it follows the original practices and rituals, and it has a large presence on Youtube. The use of this musical tradition, along with contemporary composition techniques and Christian religious texts about the Holy Spirit, resulted in a composition that choral groups in the Dominican Republic can perform during the high feast of Pentecost in the church calendar

    Predictors of suicide and differences in attachment styles and resilience among treatment-seeking first responder subtypes

    Objective: To identify the predictors of suicide for firefighters (FFs), emergency medical technicians (EMTs), and law enforcement officers (LEOs). Methods: We used baseline data from FFs/EMTs (n = 69) and LEOs (n = 81) to investigate the unique predictors for both first-responder subtypes. We conducted confirmatory factor analysis on validated assessments of posttraumatic stress disorder (PTSD) and depression.Measures of attachment, resilience, PTSD, depression, generalized anxiety, trauma history, and substance use were the independent variables in two backward stepwise regressions predicting suicide. Results: Substance use and somatic depression were significant predictors for LEOs, whereas affective depression, anhedonia, externalizing behaviors, trauma history, and generalized anxiety were significant predictors for FFs/EMTs. Limitations: These data are cross-sectional and should be modeled longitudinally over the course of treatment. Conclusion: Separate constructs influence suicide for LEOs and FFs/EMTs

    A History of Complex Simple Lie Algebras

    In 1869, prompted by his work in differential equations, Sophus Lie wondered about categorizing what he called “closed systems of commutative transformations,” while around the same time, Wilhelm Killing’s work on non-Euclidean geometry encountered related topics. As mathematicians recognized this as a division of abstract algebra, the area became known as “continuous transformation groups, but we now refer to them as Lie groups. Patterns and structures emerged from their work, such as describing Lie groups in connection with their associated Lie algebras, which can be categorized in many important ways. In this paper, we focus on Lie algebras over the complex numbers, and how simplicity and the related notion of semisimplicity, as well as root spaces and their representations, reveal that there are, up to isomorphism, surprisingly few simple complex Lie algebras, a result which Killing examined intuitively. Élie Cartan’s influence on the development of the theory of Lie algebras, though chronologically slightly later, was key to making the theory of Lie algebras the influential topic it continues to be today. He brought the rigor Lie preferred to bear on ideas and patterns generated by Killing; among other impacts of his approach, in solving the classification problem of simple complex Lie algebras

    Beer We Go! A Study of Carbonated and Nitrogenated Beers

    Get PDF
    A flavorful crisp beer is a popular, worldwide beverage. Beer can be either carbonated or nitrogenated, each giving a different sensory outcome. Carbonated beer, such as Budweiser, has a crispy and light texture, whereas nitrogenated beer, such as Guinness, has a creamy, smooth mouthfeel. A comparison study of these two different beer types was done using a Packaged Beverage Analyzer (PBA). The PBA is used to analyze the density, CO CO2, O 2, N 2, and alcohol content of various beverages, such as beer, sparkling water, and soda. The parameters assigned to the carbonated beer were container type and temperature at which it was stored. In contrast, the parameters for the nitrogenated beer were container type and widget variation. Consumers desire consistent tastes and longevity in their beverages, and these parameters could potentially impact the shelf stability and sensory outcomes of each type of beer

    Thesis: The racial, gender, and ethnic diversity of the sawmill workers was reflected in the Brotherhood of Timberworkers. The business owners resisted the organization with the general antiunion rhetoric of the era. The diverse population of the BOTW workers represents the nationwide trend away from white male labor unions

    What Determines Grades for K-12 Students?

    Get PDF
    Grades measure student academic performance. While students are often grouped based on their grades, the diversity of student background can also influence their scholarly activities. Our project investigates the different factors that can influence student grades. Using data visualization techniques and regression analysis, we find that absences and a presence of ADD/ ADHD have a negative impact on deter1nining a student\u27s grade while homework hours have a positive impact
