Perceptions of and Experiences with the Indiana Teacher Evaluation System in Physical Education
Physical educators face a difficult task of using limited time and resources to fully impact students in the gymnasium. Physical education is labeled as a noncore subject with no standardized test to evaluate student learning. In Indiana, multiple types of teacher evaluation models are used in schools across the state, causing concerns of reliability and validity for educators. The purpose of this study was to describe physical educators’ perceptions of and experiences with the teacher evaluation system in the state of Indiana. Additionally, this research examined challenges faced by teachers as they adapted to teacher evaluation systems. Solutions to the evaluative mandates were sought to address the shortcomings of Indiana teacher evaluations in physical education
Population dynamics of the eastern oyster in the northern Gulf of Mexico
This project examined the economically and ecologically valuable eastern oyster (Crassostrea virginica) in the Northern Gulf of Mexico using field and laboratory experiments. Specifically, this project focused on natural rates of settlement, growth, and mortality in a variety of temperature and salinity regimes within Breton Sound, LA. Seed and market sized oysters in cages resting on the bottom, as well as settlement tiles, were monitored at four sites in Breton Sound, LA, along what is typically a salinity gradient ranging from ~5 to ~20. In April 2010, the Caernarvon Freshwater Diversion was fully opened with the goal of minimizing the impacts of the Deepwater Horizon oil spill on wetlands, resulting in extreme low salinity (\u3c 2) at all sites through August 2010. High seed and market-sized mortality and reduced condition were observed in oysters at all sites. Perkinsus marinus infection prevalence in surviving market oysters was low at all sites and all infection intensities were light. Settlement only occurred at the highest salinity site. In May 2011, the Mississippi River flooded to record levels, resulting in low salinity (\u3c10) at all sites through June 2011. This short period of low salinity minimized disease infection intensity and settlement at all sites. Oysters at the lowest salinity site experienced high mortality and low growth. Oysters at higher salinity sites experienced limited mortality, mostly from predation, along with higher growth and condition. While low salinity may be beneficial to oyster populations by reducing P. marinus infection levels, prolonged extreme low salinity through spring and summer appears to cause heavy mortality and negatively impact recruitment in the short term. While not only is it clear that the timing and duration of freshwater inputs will significantly affect the impacts on oyster resources, it is likely that large scale global climate patterns (including El Niño and La Niña events) will also modify how and to what extent freshwater events may affect Breton Sound. This project highlights the importance of understanding the timing and duration of low salinity events and their impacts on oyster life history stages

A Shell-Neutral Modeling Approach Yields Sustainable Oyster Harvest Estimates: A Retrospective Analysis of the Louisiana State Primary Seed Grounds
A numerical model is presented that defines a sustainability criterion as no net loss of shell, and calculates a sustainable harvest of seed (\u3c75 mm) and sack or market oysters (\u3e= 75 mm). Stock assessments of the Primary State Seed Grounds conducted east of the Mississippi from 2009 to 2011 show a general trend toward decreasing abundance of sack and seed oysters. Retrospective simulations provide estimates of annual sustainable harvests. Comparisons of simulated sustainable harvests with actual harvests show a trend toward unsustainable harvests toward the end of the time series. Stock assessments combined with shell-neutral models can be used to estimate sustainable harvest and manage cultch through shell planting when actual harvest exceeds sustainable harvest. For exclusive restoration efforts (no fishing allowed), the model provides a metric for restoration success namely, shell accretion. Oyster fisheries that remove shell versus reef restorations that promote shell accretion, although divergent in their goals, are convergent in their management; both require vigilant attention to shell budgets

Terapia antirretroviral da aids em adultos acima de 50 anos: prevalência e classificação de não aderentes
Objective: To analyze the antiretroviral therapy adherence, from the determination of non-adherents’ classification variables, according behavior variables, and over 50 year old adults’ non-adherence prevalence definition, treated at Santa Maria University Hospital (SMUH), RS. Method: This research presents a quantitative approach, descriptive type and cross-sectional design. This study’s population was patients with age above 50 years old that have aids that were treated in SMUH, total of 72 patients. Data collection was developed from April 2009 to October 2010. We performed univariate (frequency percentages) and bivariate analysis, crossing the outcome (ART adherence) and behavioral variables for classification of non-adherents through the chi-square. Results: Non-adherents’ population was 21 patients, with non-adherence prevalence of 29,2%. From bivariate analysis, it was possible to determinate non-adherents’ behavior variables classification: for some reason didn’t take any of the doses; stopped taking medicines for alcoholic use; side effects prevented from taking any of the medicine doses; didn’t take this medicine during working hours. Conclusions: After defining ART prevalence and non-adherents’ behavior variables classifications determinations, it was possible to know the non adherents’ population and behavior variables that indicates this potentiality to non ingestion of 100% prescribed doses.Objetivo: Analizar la adherencia al terapia antirretroviral, a partir de la determinación de las variables de clasificación de los no adherentes, según las variables de comportamiento, y de la definición de la prevalencia de no adhesión en los adultos mayores de 50 años, atendidos en el Hospital Universitario Santa Maria / RS. Método: Investigación de enfoque cuantitativo, tipo descriptivo y transversal. La población de estudio estaba formado por pacientes mayores de 50 años que tienen el HIV / AIDS, y que estaban bajo tratamiento en HUSM, por un total de 72 pacientes. La recolección de datos se desarrolló en el periodo de abril de 2009 hasta octubre de 2010. Se realizaron análisis univariado (porcentajes de frecuencia) y bivariado, cruzando el resultado (cumplimiento del TARV) y las variables de comportamiento de la clasificación de no adherentes, por medio del test de chi-cuadrado. Resultados: La población de pacientes no adherentes fue de 21, con una prevalencia de incumplimiento del 29,2%. A partir del análisis bivariado fue posible determinar las variables de comportamiento para la clasificación de no adherentes: por alguna razón no tomó alguna de las dosis, deje de tomar los medicamentos por el consumo de alcohol, los efectos secundarios impidieron tomar alguna dosis del medicamento, no tomó el medicamento durante el tiempo que estaba trabajando. Conclusiones: Después de identificar la prevalencia de no adhesión al TARV, y la determinación de las variables que determinan la clasificación de los no adherentes, se pudo conocer la población de no adherentes y las variables de comportamiento que indican esta capacidad para la no ingestión del 100% de las dosis prescritas.Objetivo: analisar a aderência a terapia antirretroviral, a partir da determinação das variáveis de classificação de não aderentes, segundo variáveis comportamentais, e da definição da prevalência de não adesão em adultos acima de 50 anos, atendidos no Hospital Universitário de Santa Maria/RS. Método: pesquisa de abordagem quantitativa, do tipo descritivo e de delineamento transversal. A população do estudo se formou de pacientes com idade acima de 50 anos que têm HIV/aids, e que estavam em tratamento no HUSM, totalizando 72 pacientes. A coleta de dados se desenvolveu no perÃodo de abril de 2009 até outubro de 2010. Foram realizadas análises univariada (frequência percentual) e bivariada, cruzando o desfecho (adesão ao TARV) com as variáveis comportamentais de classificação de não aderentes, por meio do teste do qui-quadrado. Resultados: a população de não aderentes foi de 21 pacientes, com prevalência de não aderência de 29,2%. A partir da análise bivariada foi possÃvel determinar as variáveis comportamentais de classificação de não aderentes: por algum motivo deixou de tomar alguma das doses; deixou de tomar os medicamentos por uso de bebida alcoólica; os efeitos colaterais impediram de tomar alguma dose do medicamento; não tomou o medicamento durante o horário em que estava trabalhando. Conclusões: após definir a prevalência da não adesão ao TARV e a determinação das variáveis de classificação de não aderentes, foi possÃvel conhecer a população de não aderentes e as variáveis comportamentais que indicam esta potencialidade para não ingestão dos 100% das doses prescritas
