Latino Politicians, Activists, and Parents: The Challenge of Implementing City-Suburban Magnet Schools

This socio-political analysis focuses on various coalition members’ roles in the design and implementation of the Learning Corridor, a $126 million complex of four interdistrict magnet schools, located in the predominantly Puerto Rican south side of Hartford, Connecticut. Drawing upon historical and qualitative research methods, it examines how different Latino politicians, activists, and parents viewed the original purpose of the magnet school project -- and how they continue to address conflicts that have arisen during the past five years of implementation. In addition to archival analysis of ten years of documents and statistics, the study draws upon twenty-nine semi-structured interviews with key advocates. Major findings reveal how city-suburban magnet schools have been a two-edged blade for Hartford’s Latino residents, resulting in important tangible and symbolic gains for some, but diluting benefits that were originally slated for Hartford’s neighborhood youth

Why I Purchase What I See On Facebook: Comparing The Impact of Electronic Word-of-Mouth Between Hispanic And Non-Hispanic Consumers

This study aims to explore the role of the adoption and consumption of Facebook on Electronic Word-Of-Mouth (eWOM) among Hispanics versus African Americans, Asians, and Non-Hispanics Whites in the United States, whilst exploring the impact of attitudes towards eWOM on the likelihood to purchase something because of the “Likes” on Facebook. A national panel was used to collect the data and an ANOVA test was conducted to test the hypotheses. The results indicated Non-Hispanic White consumers were significantly less likely to use WOM than Hispanic, African Americans and Asians. Overall, Hispanics were found to be more likely than any other any group to practice eWOM, yet the difference is only significant when compared to Non-Hispanic whites. Finally, as predicted, the impact of attitudes toward eWOM on purchase behavior was the highest among Hispanics than any other group

Mineralógica, geoquímica e potencial econômico de ocorrências de terras raras do maciço granítico Pedra Branca, Goiás

Tese (doutorado)—Universidade de Brasília, Instituto de Geociências, Programa de Pós-Graduação em Geologia, 2019.O presente estudo tem como principal enfoque os elementos terras raras (ETR) que ocorrem em importantes concentrações no maciço granítico Pedra Branca, situado na parte leste na Província Estanífera de Goiás, mais precisamente na Subprovíncia Estanífera Paranã. O maciço possui importantes depósitos de estanho e é constituído por granitos do Tipo A, metaluminosos a peraluminosos, com idade entre 1740 e 1769 Ma. A Faixa Placha é o depósito de estanho mais importante do Maciço Pedra Branca e apresenta concentrações elevadas de ETRY, tanto no minério de Sn quanto no granito parental e nos granitos greisenizados com potencial para serem explotados economicamente como subproduto do estanho. Os valores ultrapassam 1000 ppm em ETRL e alcançam 500 ppm em ETRPY. Os minerais portadores de ETR no granito parental são allanita, monazita, xenotima, torita, apatita e zircão. Esses minerais, exceto zircão, são alterados, dando origem a monazita secundária, silicatos, fluorcarbonatos e oxifluoretos, que são responsáveis pela concentração de ETR nos granitos greisenizados e greisens e pela disponibilização desses metais para a fração argila dos saprolitos e solos. Análises de troca iônica nos saprolitos e solos de um perfil da Faixa Placha mostram que as extrações na fração argila são mais ricas em ETRY em relação às extrações em rocha total, apresentando valores entre 3425 e 36762 ppm e entre 2804 e 21689 ppm respectivamente. Os ETR encontram-se mais ricos na parte basal do perfil, principalmente os ETRL. A composição mineralógica e as concentrações de ETRY sugerem grande potencial econômico no depósito da Faixa Placha para recuperação de terras raras como subproduto da mineração de estanho. Adicionalmente, as concentrações de ETRs como íons trocáveis no perfil de intemperismo indicam potencial para que a Faixa Placha e áreas vizinhas constituam um importante depósito de ETRY do tipo adsorção iônica.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES).The present study has as its main focus the rare earth elements (REE) that occur in important concentrations in the Pedra Branca granite massif, located in the eastern part of the Goiás Tin Province, more precisely in the Paranã Tin Subprovince. The massive has important tin deposits and consists of metaluminous to peraluminous A-type granites, aged between 1740 and 1769 Ma. The Faixa Placha is the most important tin deposit of the Pedra Branca Massif and presents high concentrations of REEY in the parental granite, in the greisenized granites and in the tin ore. The values are above 1000 ppm in LREE and reach 500 ppm in HREEY. The minerals with REE in the parental granite are allanite, monazite, xenotime, thorite, apatite and zircon. These minerals except zircon, are altered, giving rise to secondary monazite, REE- silicates, REE-fluorcarbonates and REE-oxyfluorides, which are responsible for the concentration of REE in greisenized granites and greisens and the availability of these metals to the clay fraction of soils and saprolite. Ion exchange analyses on saprolite and soil in a weathering profile of Faixa Placha, show that the extraction from the clay fraction are more enriched in REEY in relation to the extraction from whole rock, with values between 3425 and 36762 ppm and between 2804 and 21689 ppm respectively. The REE are more enriched in the basal part of the profile, especially the LREEs. Both the REEY concentrations and mineral compositions suggest an important economic potential of the Faixa Placha deposit for recovery of REE as by-product of tin mining. In addition, the exchangeable REEY concentrations in the weathering profile indicate the potential of the Faixa Placha and nearby areas to constitute an important REEY deposit of the ion-adsorption-type

Sexual dimorphism in cranial tomography and cranial volume

Orientador: Luiz Francesquini JúniorDissertação (mestrado profissional) - Universidade Estadual de Campinas, Faculdade de Odontologia de PiracicabaResumo: A antropometria sempre intrigou o ser humano desde as civilizações egípcias e gregas já observavam e estudavam a relação das diversas partes do corpo. Assim, a antropologia estuda o ser humano sob o aspecto cultural e físico tendo na sua vertente forense a finalidade de servir como método auxiliar no estudo da identidade sob o critério físico. Na busca da identificação do individuo, o primeiro passo é estimar o sexo. No estudo realizado buscou-se relacionar as medidas cranianas em TC e volume craniano em ossos secos com sexo. Os crânios secos e as TC pertencem ao Biobanco Osteológico e Tomográfico da FOP/UNICAMP constando de 112 TC de homens e 87 TC de mulheres, todas com idade, ancestralidade e causa da morte conhecidas. A mensuração se deu com o software OnDemand3D® e as medidas: Glabela-Metalambda; Bregma-Básio e Eurio-Eurio. Para determinar o volume craniano foi utilizado sementes de soja preenchendo toda a cavidade. Após a análise estatística por meio do software IBM® SPSS® 25 Statistics ficou constatado que todas as medidas avaliadas são dimórficas, sendo possível elaborar um modelo de regressão logística denominado SEX 2019= [-18,087+(5,937xVC) +(-0,076x(Br-Ba))]. Observou-se que o método utilizado resulta em 80,4% de sensibilidade, 66,7% de especificidade e 74,4% de acurácia, se mostrando eficaz na predição do sexo. O modelo de regressão obtido permite a estimativa do sexo nos casos onde se disponha de TC e crânio de indivíduos desaparecidosAbstract: Anthropometry has always intrigued humans, Egyptian and Greek civilizations already observed and studied the relationship of the various parts of the body. Thus, anthropology studies the human being under the cultural and physical aspect, has in its forensic aspect the purpose of serving as an auxiliary method in the study of identity under the physical criterion. In the pursuit of individual identification, the first step is to estimate sex. In this study, we sought to relate cranial CT measurements and cranial volume in dry bones with sex. The dried skulls and CT scans belong to the FOP / UNICAMP Osteological and Tomographic Biobank consisting of 112 male CT and 87 female CT, all with known age, ancestry and cause of death. Measurement was made with OnDemand3D® software and measurements: Glabela-Metalambda; Bregma-Basio and Eurio-Eurio. To determine the cranial volume was used soybean seeds filling the whole cavity. After statistical analysis using the IBM® SPSS® 25 Statistics software, it was found that all the measures evaluated are dimorphic, and it is possible to elaborate a logistic regression model named SEX 2019 = [-18,087+ (5,937xVC) + (- 0,076x ( Br-Ba))]. It was observed that the method used results in 80.4% sensitivity, 66.7% specificity and 74.4% accuracy, showing to be effective in predicting sex. The regression model obtained allows the estimation of sex in cases where CT and skull of missing individuals are availableMestradoGestão e Saúde ColetivaMestra em Gestão e Saúde Coletiv

Levadura seca como inóculo para fermentar rones a escala de planta piloto

The use of distillers' dried yeast as inoculum for rum fermentations was studied on a pilot plant scale. Two fermentation procedures (batch and fed batch) and four levels of dry yeast (0.5, 1.0, 1.5 and 2.0 g/L) were tested. The fermentations were followed for 36 hours. Product yields at 24 hours and 36 hours were determined. The resultant fermentation rate was below the rate required by the local industry (close to completion after 30 hours). This drawback is further complicated by the fact that dried yeast is not stable and has a shelf life that can vary from 1 to 12 months, depending on ambient storage conditions.Se estudió el uso de levadura seca como inóculo para fermentaciones de ron a escala de planta piloto; se probaron dos métodos de fermentación (por tandas y semicontinuo) y cuatro cantidades de levadura seca (0.5, 1.0, 1.5 y 2.0 g./l.). Estas fermentaciones se observaron por 36 horas. Se calculó el rendimiento de etanol a las 24 y 36 horas. La fermentación fue menos rápida de lo que requiere la industria local: fermentación completa a las 30 horas. Este inconveniente se complica porque la levadura va perdiendo actividad con el tiempo, ya que su utilidad, según indicado por el fabricante, fluctúa entre 1 a 12 meses según las condiciones de almacenamiento
