In this study, I explored the motivations of high school instrumental music teachers to participate in competitive jazz festivals, specifically those sponsored by the California Music Educators Association (CMEA) Bay Section. I was interested in learning the specific needs participation in competitive festivals satisfied for high school music educators. Based on the tenets of Self-Determination Theory (SDT), I investigated whether the three basic psychological needs of autonomy, competency, and relatedness were among the needs being satisfied. I was curious whether an individual’s background in jazz or any other factors had any bearing on their decision to participate. Through interviews teachers shared their experiences, both positive and negative, of participating in competitive jazz festivals. The following research questions guided this study: 1. What motivates high school music teachers to participate in competitive jazz festivals? 2. What specific needs are satisfied through their participation? 3. How does one’s jazz background influence motivation to participate in CMEA Bay Section events? In answering the aforementioned research questions, I chose a case study design. Interviews with twenty-nine high school instrumental music teachers were conducted at their respective work sites, except for three phone interviews and one via electronic mail. Five themes identified through data analysis about festivals specifically included feelings about competition, judging, negative feedback from adjudicators, hearing and seeing other groups, and a suggestion for the addition of a clinic for all participating groups. Six general themes about CMEA Bay Section or participants’ feelings included more progressive thinking, a perception that youth among adjudicators was inadequately represented, a notion that festivals provided opportunities for process and growth, a feeling that many were forced to weigh the costs versus the benefits of participation, an expressed feeling of isolation in the profession, and a lack of awareness on the part of administrators about their participation in CMEA Bay Section jazz festivals.

Adipocere is a waxlike substance that can encase bodies after death if certain conditions are met: temperature, moisture content, other environmental factors, and the presence of bacteria that transform fatty acids into the hydroxy- and oxy-fatty acids that make up much of the adipocere substance. Adipocere formation arrests the process of decomposition, making it difficult for forensic pathologists to determine a post-mortem interval. The thesis identifies several issues with current research into early-stage adipocere. Firstly, the majority of scientific papers on the subject make use of pig adipose as a stand-in for human adipose due to ethical concerns. However, this traditional forensic method is not suited for studies into adipocere formation: the fatty acid profiles of pigs and humans have differing ratios of saturated and unsaturated fatty acids, making them an unreliable analog for adipocere testing. In addition, most studies assume a three-month timeframe for the formation process when preparing their experimental design, a timeframe thrown into question by both current data and several existing case studies demonstrating more rapid adipocere formation. Lastly, testing takes place in static environments, which does not reflect actual field conditions. There have been cases that suggest adipocere formation ceases during colder months once decomposition has initially halted. In these cases, the adipocere formation begins again once temperatures return to 22°C or higher. Another issue noted is the lack of chemical analysis conducted on early-formation adipocere. The changes in fatty acid ratios that take place during the process are not typically looked at by scientists investigating the phenomenon or forensic pathologists dealing with adipocere cases, but may offer a viable means of narrowing down post-mortem intervals and contribute to better timelines for pathologists and law enforcement. This thesis ultimately recommends a number of additional research directions necessary for building a temperature zone-based database of case and laboratory results, particularly ones that take into account the variable formation timeframe observed in previous experiments and case studies. / 2031-01-01

The central argument of this project is that meaningful and intelligible experience is conditioned by the determinate relationship between realms of reality, and that our humanity is grounded on the semiotic process of symbolic references, which is manifest in Charles S. Peirce’s and Robert C. Neville’s theories of determination. However they are contained by the past such processes of determination can be extended to the future through transformative effort. My investigation ranges over multiple paths that lead toward determinate processes, by suggesting that the problem of interpretation and of the intelligibility of experience can be solved only in reference to the full purview of determinate features of experience. In his theory of determination, Peirce considered two processes of determination, the semiotic process and epistemology. The semiotic process is an extensional process from object to interpretant that consists of an infinite chain of references that can be spatially reversible. The epistemological process of determination is temporal and irreversible, where the idea grows into the individual mind, as the universe is unfolded by the agency of mind. Peirce’s study of the logic of individuals of Duns Scotus is to find answers for the problem of individuality. For Peirce, God is individualized in the course of determination and at the same time determines all possible determinations. Due to his adopting the Scotian sense of necessity, Neville also adopts Duns Scotus’s logic of individuals to his theory of determination and valuation. As revealed in his theory of determination, in the ontological act of creation God becomes individual as a creator, an individual as the determiner of all possible determinations. In his theory of determination, Neville proposes modes of determination at the ontological level, as well as a collection of cosmological determinations. Neville works “inter-cosmologically” in order to account for the fundamental conditions of our knowing that brings ontological and cosmological determinations together. In their theory of interpretation, Peirce and Neville suggest a triadic system of semiotic network. Among other things, Neville provides a more sophisticated version of theory of interpretation, which involves realms of intelligibility. Both Peirce and Neville symbolism allows for the pragmatic semiotics based upon a brokenness of signs, which opens for further interpretation.

Além disso, este trabalho apresenta estudos exploratórios acerca da influência de parâmetros que afetam as análises em LIBS. O instrumento foi montado empregando-se óptica e sistema de detecção de última geração: um detector ICCD, um policromador echelle e um laser Q-switched de Nd:YAG. Três configurações do sistema LIBS foram avaliadas. No último arranjo do sistema, o pulso de laser era refletido por um espelho dicróico à 45º para uma lente de distância focal de 25 cm que focava o pulso de laser na superfície da amostra. A radiação foi coletada por uma lente de curta distância focal e depois enviada para o echelle, por uma fibra óptica, e posteriormente para o ICCD. Na análise qualitativa foram avaliados os espectros de uma placa de cobre e zinco, obtendo-se espectros condizentes com a literatura, de acordo com a resolução do echelle. Na avaliação quantitativa, determinou-se manganês em aços acalmados. O sistema apresentou resposta às diferentes concentrações de manganês em 293,30 nm e curvas analíticas foram obtidas. A energia do pulso de laser mostrou ser um fator determinante no desempenho da análise quantitativa. Outros parâmetros como tempo de integração do sinal, tempo de atraso, ganho do MCP, co-adição de pulsos e distância foco-amostra também mostraram ter influência na análise quantitativa. Imagens de MEV e mapeamentos de EDS das crateras formadas pelo laser foram ferramentas importantes para o entendimento do processo de interação laser-amostra-atmosfera / Abstract: In this work a time resolved LIBS instrument (TRELIBS) was built and its performance evaluated in qualitative and quantitative analysis. Additionally, exploratory studies are presented on the influence of parameters that affect the LIBS analysis. The instrument was built employing optical systems and devices of modern technology: an ICCD device, an echelle polychromator and an Q-switched Nd:YAG laser. Three configurations of LIBS system were evaluated. In the last configuration, the laser pulse was reflected by a dicroic mirror at 45º to a lens of 25 cm focal distance that focused the laser pulse on the sample surface. The plasma emission was collected by a lens of short focal distance and sent to the echelle, through of an optical fiber, and later to the ICCD. In qualitative analysis, spectra of copper and zinc foils were evaluated and the spectral lines were found in agreement with literature, considering the echelle resolution. In quantitative analysis, manganese was determined in killed steel. The system presented signals at 293,30 nm whose intensities changes in function of manganese concentration and analytical curves were obtained. The laser pulse energy showed to be an important factor for the success of quantitative analysis. Others parameters such as width, delay time, MCP gain, accumulated laser pulses and distance sample-focusing lens also showed have influence in quantitative analysis. MEV images and surface scanner by EDS of the craters formed by laser were important tools to understanding laser-sample-atmosphere interaction processes / Mestrado / Quimica Analitica / Mestre em Química
