This is a qualitative study using participant observation, interviews with caregivers, the Zarit Burden Interview, and a diary, where for three months, three patients with Alzheimer's disease at an advanced stage will undergo a physical therapy program. Every session will be accompanied by family caregivers, that will be instructed as to the environmental awareness, accessibility, physical care with the patient in addition to socialization and family integration. Creating, in this way, a new physical therapy approach aimed at improvement of behavioral changes in Alzheimer's disease at an advanced stage / A partir de uma abordagem mais humanizada, envolvendo o toque fisioterapêutico em condutas ortopédicas e respiratórios, da criação de um vínculo com o cuidador e dadas orientações quanto ao cuidado físico e social no sujeito com Alzheimer em fase avançada, é possível trabalhar com a fisioterapia sob um olhar gerontológico, estimulando o doente e pensando em controlar as alterações comportamentais, principalmente a apatia. Esse é um estudo qualitativo, que utiliza a observação participante, uma entrevista, o inventário de sobrecarga do cuidador, avaliação fisioterapêutica e um diário de campo, onde durante três meses, três sujeitos com Doença de Alzheimer em fase avançada serão submetidos a um programa de tratamento fisioterapêutico. Toda sessão será acompanhada pelo cuidador familiar, sendo este orientado quanto à alterações no ambiente, acessibilidade, cuidados físicos com o doente além de socialização e integração familiar. Criando assim uma nova abordagem fisioterapêutica visando melhora das alterações comportamentais na doença de Alzheimer em fase avançada

The purpose of this qualitative study was to collect descriptive data pertaining to students’ perceptions regarding the use of tap dance movement and its effect on the understanding of rhythms found in choral literature. This enquiry investigated the following questions: (a) What are the perceptions of high school students regarding the difficulty of tap dance movement? (b) What are the perceptions of high school students regarding the effectiveness of tap dance movement as a method toward promoting their rhythm accuracy when performing rhythms featured in choral music? (c) What are the perceptions of high school students regarding the effectiveness of integrating tap dance movement with the study of select rhythm patterns chosen from choral literature in their retention of the rhythms? Over a five-month period, high school choral ensemble members (N = 88) were taught twenty-five rhythm patterns excerpted from choral literature, integrating tap dance movement with the instruction. The results revealed that the difficulty level of the movement, tempo at which it is executed, the changing of feet while performing the movement, and the amount of tap experience an individual possesses influence students’ perceptions regarding the degree of complexity of tap dance movement. Additionally, the data indicate the enjoyment of the movement, the demonstrations of the movement, the integration of music with the movement, the use of step names and counting, and the use of tap shoes are elements related to tap dance movement that students perceived to help promote their understanding of rhythms found in choral music. Moreover, the results pertaining to the students’ perception of how tap dance movement was an effective method of promoting their retention of rhythms found in choral music indicate a lack of agreement. While there were singers who found the movement to benefit their ability to memorize the examined rhythms, there was a comparable amount of students who indicated that they were unable to remember the rhythms following the instruction. Lastly, the findings provide information regarding the specific types of movements that students found beneficial to their rhythmic comprehension, adding to the existing literature and useful for replication in future studies.

In the first chapter, I consider the institutional structures as well as the doctrines typically encountered in the surface water sector. To investigate the sources and methods of government support in the water sector, I categorize different sorts of government support according to the location of water along the water cycle. I conclude the section with examples of observed water markets. In the second chapter, I consider the problem of water usage, developing a model to analyze the optimal pricing of water within a second-best economy. As a water supplier, the local government may price discriminate across consumers and farmers. I introduce the second-best pricing scheme, derive conditions for the marginal-cost pricing and inverse-elasticity rules, and analyze when the government optimally deviates from these two pricing schemes. In the third chapter, I provide an analysis of the data I collected from Turkey. First, I examine the data on reservoir flows, including service share and fixed costs of the reservoirs. Then, I provide details about the relationship between the quantity and price of irrigation and of tap water. Finally, in the fourth chapter, I apply the theoretical framework to the data from Turkey. In Turkey, the current water-pricing policy is dictated by the sole objective of breaking-even in each period. This results in large withdrawals, which is not sustainable in the long-run, hence not optimal. I analyze the dynamic optimal water resource management problem of a benevolent government. I compare the implications of the current and the optimal pricing policies.

Dans les cellules eucaryotes, lexport des ARN messagers du noyau vers le cytoplasme est un processus complexe et régulé. Les messagers matures sont transportés par le récepteur dexport TAP/NXF1, qui est recruté au niveau des messagers par différents adaptateurs comme les protéines Aly/REF, UAP56 et les protéines SR. Dans le cadre dune infection virale, en plus des messagers cellulaires, de nombreux messagers viraux doivent être transportés efficacement dans le cytoplasme pour y être traduits. Il est maintenant établi que les herpesvirus codent pour une famille conservée de gènes dont les produits agissent en tant que facteurs dexport et régulent le transport des transcrits viraux. Cette famille inclut la protéine IE4 du virus de la Varicelle et du Zona (VZV). Les principales caractéristiques de ces facteurs dexport viraux sont leur capacité à faire la navette entre le noyau et le cytoplasme, leur domaine de liaison à lARN, et leur capacité à interagir avec des facteurs intervenant dans lexport des messagers cellulaires. Avant cette étude, les données montraient que la protéine IE4 agit comme un régulateur important de lexpression des gènes viraux et cellulaires, mais les mécanismes impliqués nétaient pas clairement définis. Dans ce travail, nous avons identifié de nouveaux partenaires cellulaires de la protéine IE4, et, bien que des différences existent, nous avons montré que la protéine IE4 partage les caractéristiques des facteurs dexport viraux. Nous avons montré que la protéine IE4 interagit avec trois protéines SR, à savoir ASF/SF2, 9G8 et SRp20. Nous avons identifié le domaine dinteraction au sein de la protéine IE4 et montré que ces interactions ne sont pas dépendantes de la présence dARN. Nous avons démontré que la protéine IE4 interagit avec la principale kinase phosphorylant les protéines SR, SRPK1, et quelle est phosphorylée par cette kinase. Nous avons montré que la protéine IE4 se lie à lARN, et que la présence dARN stabilise des complexes contenant la protéine IE4 et les facteurs dexport cellulaires TAP/NXF1 et Aly/REF. Enfin, nous avons déterminé linfluence de la protéine IE4 sur lexport de messagers rapporteurs, et clairement montré que linfection par le VZV utilise le facteur dexport TAP/NXF1 pour exporter certains transcrits viraux. Nous avons donc mis en évidence un nouvel exemple de facteur dexport viral et proposé en modèle dexport des messagers viraux régulé par la protéine IE4. Nos résultats démontrent clairement que les herpesvirus ont développé différents mécanismes pour réguler lexport des ARN dans le but daltérer lexpression des gènes cellulaires au profit de lexpression des gènes viraux.

Previous studies have shown that low-income Latinos frequently drink bottled water instead of tap water and might be at increased risk for dental caries from unfluoridated bottled water. The goals of this study were to: 1) determine if a difference exists between grab samples of municipal tap water and bottled water used by families in Nogales, Arizona in chemical and microbial contaminants; 2) understand the risk perceptions these low-income families have about both their publically supplied tap water, bottled/vended water; and 3) examine whether families have adequate fluoride levels in their drinking water for optimal dental health. Tap and bottled water samples were collected from thirty of these households for analysis of drinking-water contaminants regulated by the U.S. Environmental Protection Agency (USEPA). Bottled water included small (0.5 L) and large (3.8 L), individually sealed water bottles as well as water vended into reusable containers from self-service vending machines or from water stores. Some of the large bottles were purchased sealed, but had been previously opened and partially consumed by study participants. In addition to the 30 households mentioned above, an additional sixty low-income Latino households, who primarily drink bottled water, were also recruited for this study to complete a questionnaire on risk perceptions related to drinking water consumption, water storage practices, and fluoride supplementation. There were no significant differences in the concentration of chemical contaminants between tap, bottled and vended water, and none of the chemical concentrations exceeded USEPA regulations. Escherichia coli (E. coli) was confirmed in 3% (1/30) of tap, 0% (0/8) of sealed bottled, 40% (2/5) of previously opened bottled, and 35% (6/17) of vended water samples. One of the 3 samples collected directly from a vending machine had an E. coli concentration of 0.33 CFU/100 mL. None of the 10 samples collected directly from sealed bottles purchased directly from the store had any E. coli detected. While no significant differences were observed in the chemical quality of water samples, results suggest that secondary contamination in the home contributes to higher levels of E.coli in water from partially consumed larger water bottles or water stored in reusable containers. Families who reported cleaning large reusable water containers with soap or hot water had significantly lower E.coli (p=0.003) in their drinking water than those who rinsed with only water. Respondents viewed bottled water to be significantly safer to consume than tap water (p<0.001). On a Likert scale from 1 (low risk) to 5 (high risk), "drinking tap water in Nogales, Arizona" received an average score of 4.7, which was significantly higher than the average perceived risk of smoking (µ= 3.5, p<0.001) or of "drinking tap water in San Francisco, California" (µ= 3.4, p<0.001), and as risky as "drinking and driving" (µ= 4.8, p=1.00) and "drinking tap water in Nogales, Sonora, Mexico" (µ= 4.8, p=1.00). Additionally, 98% (88/90) of respondents feared that drinking local tap water could result in illness. The majority of respondents (79%, 71/90) did not drink their tap water because of fear of contamination and would drink their tap water if they knew it was safe, regardless of the taste (73%, 66/90).Fluoride was detected in 53% (16/30) of tap-water samples and only in one bottled-water sample. However, only 27% (8/30) of tap-water samples had fluoride levels within the recommended range (0.7-1.2 mg/L) by the American Dental Association for optimally fluoridated water. From multiple logistic regression, children in a household were less likely to have cavities if their parents reported using fluoridated mouthwash (p<0.001) or visited the dentist yearly (p<0.001). None of the participants reported discussing the type of water they drank or fluoride supplementation with any healthcare providers. Results suggest that secondary contamination in the home is contributing to significantly higher levels of bacteria in vended water stored in reusable containers. In addition, fear of illness from contamination of tap water is an important contributing factor to increased use of bottled water. Interventions could be developed to educate families about how to keep their reusable water containers clean, reduce perceived risks associated with tap-water consumption, and emphasize the importance of fluoride supplementation if families continue drinking bottled water.
