La aplicación del robot Bee-Bot para el desarrollo de las habilidades de comunicación e interacción social del alumnado con Trastorno del Espectro Autista (TEA)

Pérez-Vázquez, Elena 29 October 2021 (has links)
En las últimas décadas, la utilización de las Tecnologías de la Información y la Comunicación (TIC) se ha extendido a diferentes ámbitos de nuestra sociedad. Entre dichos ámbitos nos encontramos con la educación. De manera general, las escuelas han ido incorporando diferentes herramientas tecnológicas con el objetivo de mejorar el proceso de enseñanza-aprendizaje del alumnado. Estas herramientas innovadoras mejoran no solo el aprendizaje, sino también la participación y la presencia del alumnado con Necesidades Específicas de Apoyo Educativo en los colegios ordinarios. Entre este grupo de alumnos y alumnas encontramos aquellos con Trastorno del Espectro Autista (TEA). Un trastorno del neurodesarrollo que afecta la capacidad de los individuos para comunicarse y desarrollar interacciones sociales, junto con la presencia de patrones restringidos y conductas, intereses y actividades repetitivas. Esta línea de diagnóstico trae consigo un grupo muy heterogéneo de individuos, para los cuales es muy complicado identificar un método concreto de aprendizaje. La utilización de las TIC ha añadido nuevas posibilidades para su intervención educativa. Entre estas herramientas tecnológicas ha experimentado un gran auge la robótica educativa la cual, gracias a su predictibilidad, su capacidad para actuar como soporte visual y secuenciar la presentación de la información se constituye como una herramienta ideal para la enseñanza de este alumnado. No obstante, el elevado coste de los robots, así como la falta de dispositivos, hace que la mayoría de las aplicaciones se desarrollen en un entorno clínico y no educativo. Ante este panorama, la presente investigación tiene por objetivo general evaluar la competencia en el área de comunicación e interacción social del alumnado con Trastorno del Espectro Autista (TEA) a partir de la aplicación en función de la utilización de la robótica. Para ello, se opta por un enfoque cuantitativo cuasi experimental con un diseño de dos grupos no equivalentes con pretest y postest y grupo control. Donde tanto los participantes del grupo control, quienes realizan las tareas sin utilizar la robótica, como los participantes del grupo experimental, quienes realizan las tareas con mediación del robot Bee-bot, son alumnos y alumnas con TEA. y grupo control. El procedimiento utilizado para la selección de la muestra fue el muestreo no probabilístico disponible entre las unidades específicas de Comunicación y Lenguaje de la ciudad de Alicante (UECil). Por otro lado, el instrumento utilizado fue el cuestionario diseñado adhoc CACIS-TEA y el análisis de datos se realizará con el paquete estadístico SPSS para Windows (Statistical Package for Social Sciences) en su versión 21. El análisis de datos se basa en pruebas no paramétricas. Los resultados indicaron variaciones en un mayor número de ítems del cuestionario para el alumnado del grupo experimental. Asimismo, también indican que alumnado del grupo experimental ha mejorado significativamente sus habilidades en el área de comunicación e interacción social tras el desarrollo del programa de intervención mediado por el robot Bee-Bot, respecto al alumnado del grupo control en el que se ha aplicado una metodología sin TIC. Y, por último, se observan diferencias significativas dentro del grupo experimental en función del tipo de comunicación, el género y el nivel actual de competencia (NAC). Como conclusión se puede afirmar que este la robótica posee potencialidades para el aprendizaje del alumnado con Trastorno del Espectro Autista.

Coffee, Tea Consumption and Endometrial Cancer Risk: Women's Health Initiative Observational Study

Giri, Ayush 01 January 2011 (has links) (PDF)
Approximately 40,000 women in the U.S. are diagnosed with endometrial cancer annually. Biological data suggest coffee or tea consumption may lower endometrial cancer risk through estrogenic and insulin-mediated pathways. Epidemiologic data are inconsistent, with two of three prospective cohort studies showing an inverse association with coffee consumption and two prospective cohort studies finding no association with tea consumption. We used publicly available data from the Women's Health Initiative Observational Study to evaluate the association between coffee, tea and endometrial cancer risk. We identified 48,912 eligible post-menopausal women with a mean follow-up time of 7.5 years. During this period there were 452 incident endometrial cancer cases. We used Cox-proportional hazard models to evaluate the effects of coffee and tea consumption on endometrial cancer risk, while adjusting for potential confounders including age, body mass index and hormone therapy use. Overall, we did not find an association between coffee consumption and endometrial cancer risk. Compared to women who did not drink coffee on a daily basis (none or < 1 cup/day), the multivariable adjusted hazard ratios for women who drank 2-3 cups/day was 0.95 [95% confidence interval (CI) 0.74,1.22] for total coffee, 0.91 (95% CI 0.68,1.23) for regular coffee, and 0.94 (0.62,1.42) for decaf coffee. Compared to obese women who did not drink coffee on a daily basis (none or < 1 cup/day), the multivariable adjusted hazard ratios (HR) for obese women who drank ≥ 2cups/day as reported at baseline were: 0.79 (95% CI 0.53,1.17] for total coffee, 0.62 (95% CI 0.39,1.00) for regular coffee, and 0.78 (95% CI 0.40,1.50) for decaf coffee. Furthermore, obese women who consistently reported drinking ≥2 cups of regular coffee/day had an even further reduced risk [HR 0.40 (95% CI 0.18,0.91)]. In comparison to women who did not drink tea on a daily basis, obese women who drank 1 cup and ≥ 2cups of tea/day had multivariable adjusted hazard ratios of 0.45 (95% CI 0.22,0.92) and 0.99 (95% CI 0.60,1.62), respectively. The results from our study suggest that regular coffee consumption may be protective against endometrial cancer among obese postmenopausal women, with inconclusive results for tea. Our study adds to the biological understanding and to the small body of prevalent epidemiologic literature on coffee consumption and endometrial cancer risk.

Determination of in vitro effects of aqueous extract of camellia sinensis on human sperm functions

Setumo, Mmaphulane Abigail January 2021 (has links)
Thesis (M.Sc. (Medical Sciences)) -- University of Limpopo, 2021 / Infertility, defined as the inability to conceive following one year of unprotected sexual intercourse, respectively affects 25% of couples globally. Oxidative stress (OS) has been greatly related to the idiopathic cause of infertility and Camellia sinensis contains antioxidants that may enhance reproductive functions. This study focussed on the effects of Camellia sinensis (green and black tea) on human sperm functions in both normal and abnormal samples. Semen samples (n= 59) collected from donors were liquefied, analysed, and classified as normal (n=40) and abnormal (n= 19) using the WHO criteria. Samples were washed and exposed to aqueous leaf extracts of green and black tea (0, 0.4, 4, 40, 405 μg/ml) for 1 hour. Human Tubular Fluid (HTF) served as the control. The respective sperm parameters were analysed (sperm motility, vitality, DNA fragmentation, mitochondrial membrane potential (MMP), capacitation and acrosome reaction (CTC) and reactive oxygen species (ROS). Green and black tea significantly increased vitality, and intact MMP, while it significantly reduced, CTC, and intracellular ROS as well as DNA fragmented spermatozoa in both normal and abnormal samples compared to the control (p<0.05). A significant increase in sperm CTC, ROS, with a decrease in sperm vitality, and intact MMP was observed in the abnormal compared to the normal samples (p<0.05). No significant change in motility was observed between normal and abnormal samples compared to their respective controls, in both green and black tea (p>0.05). Camellia sinensis improved human sperm function in vitro and may be attributed to its antioxidant activity. / National Research Foundation (NRF)

Stoneflies of Unusual Size: Population Genetics and Systematics Within Pteronarcyidae (Plecoptera)

Sproul, John S. 12 July 2012 (has links) (PDF)
Chapter 1. The family Pteronarcyidae (Plecoptera) is a highly studied group of stoneflies and very important to a wide variety of aquatic studies. Several phylogenies have been proposed for this group recent decades, however there is little congruence between the various topologies. The present study revises the phylogeny of the group by combining molecular data from mitochondrial cytochrome oxidase subunit II, ribosomal subunit 12S, ribosomal subunit 16S, and nuclear loci ribosomal subinit 18S and Histone H3, with published morphological data in a parsimony-based total evidence analysis. The analysis produced a well-supported phylogeny with novel relationships within the genus Pteronarcys. Maximum Likelihood and Bayesian analyses produced topologies congruent with parsimony analysis. Character mapping revealed several homoplasious morphological characters that were previously thought to be homologous. Chapter 2. Phylogeographic studies in aquatic insects provide valuable insights into mechanisms that shape the genetic structure of aquatic communities. Yet studies that include broad geographic areas are uncommon for this group. We conducted a broad scale phylogeographic analysis of P. badia across western North America. In order to allow us to generate a larger mitochondrial data set, we used 454 seqeuncing to reconstruct the complete mitochondrial genome in the early stages of the project. Our analysis reveals what appears to be a complex history of isolation and multiple invasions among some lineages. The study provides evidence of multiple glacial refugia and suggests that historical climactic isolations have been important mechanisms in determining genetic structure of insects in western North America. Our ability to generate a large mitochondrial data set through mitochondrial genome reconstruction greatly improved nodal support of our mitochondrial gene tree, and allowed us to make stronger inference of relationships between lineages and timing of divergence events.

Observations, Thermochemical Calculations, and Modeling of Exoplanetary Atmospheres

Blecic, Jasmina 01 January 2015 (has links)
This dissertation as a whole aims to provide the means to better understand hot-Jupiter planets through observing, performing thermochemical calculations, and modeling their atmospheres. We used Spitzer multi-wavelength secondary-eclipse observations to characterize planetary atmospheres. We chose targets with high signal-to-noise ratios, as their deep eclipses allow us to detect signatures of spectral features and assess planetary atmospheric structure and composition with greater certainty. Chapter 1 gives a short introduction. Chapter 2 presents the Spitzer secondary-eclipse analysis and atmospheric characterization of WASP-14b. The decrease in flux when a planet passes behind its host star reveals the planet dayside thermal emission, which, in turn, tells us about the atmospheric temperature and pressure profiles and molecular abundances. WASP-14b is a highly irradiated, transiting hot Jupiter. By applying a Bayesian approach in the atmospheric analysis, we found an absence of thermal inversion contrary to theoretical predictions. Chapter 3 describes the infrared observations of WASP-43b's Spitzer secondary eclipses, data analysis, and atmospheric characterization. WASP-43b is one of the closest-orbiting hot Jupiters, orbiting one of the coolest stars with a hot Jupiter. This configuration provided one of the strongest signal-to-noise ratios. The atmospheric analysis ruled out a strong thermal inversion in the dayside atmosphere of WASP-43b and put a nominal upper limit on the day-night energy redistribution. Chapter 4 presents an open-source Thermochemical Equilibrium Abundances (TEA) code and its application to several hot-Jupiter temperature and pressure models. TEA calculates the abundances of gaseous molecular species using the Gibbs free-energy minimization method within an iterative Lagrangian optimization scheme. The thermochemical equilibrium abundances obtained with TEA can be used to initialize atmospheric models of any planetary atmosphere. The code is written in Python, in a modular fashion, and it is available to the community via http://github.com/dzesmin/TEA. Chapter 5 presents my contributions to an open-source Bayesian Atmospheric Radiative Transfer (BART) code, and its application to WASP-43b. BART characterizes planetary atmospheres based on the observed spectroscopic information. It initializes a planetary atmospheric model, performs radiative-transfer calculations to produce models of planetary spectra, and using a statistical module compares models with observations. We describe the implementation of the initialization routines, the atmospheric profile generator, the eclipse module, the best-fit routines, and the contribution function module. We also present a comprehensive atmospheric analysis of all WASP-43b secondary-eclipse data obtained from the space- and ground-based observations using BART.

The Future of the Tea Party: A Comparison of the Progressive (Bull Moose) Party and the Tea Party Movement

Bailey, Kendall Lyons 04 September 2012 (has links)
The Tea Party Movement (TPM) has emerged as an important player in United States politics by promoting fiscal conservatism, limited government, free market economics, and Constitutionalism. Candidates championing these TPM values have had some successful campaigns, particularly in the 2010 congressional primary and general elections. In doing so, TPM candidates focused their attacks on President Obama and his supporters in Congress, drawing attention to the increase in government spending and the growing budget deficit. The niche focus of the TPM combined with the strength of the U.S. two-party system and voters' partisan loyalties may limit the long-term effectiveness of the group. An analysis of campaign rhetoric from a sample of successful TPM House candidates highlights similarities in language used by the sampled TPM candidates in conveying TPM values. The discussion of similar economic and political climates of the Progressive (Bull Moose) Party and the Tea Party Movement eras provides for a historical comparison from which to predict the future of the TPM. In sum, this thesis suggests that the Tea Party Movement will likely expire with an improved economy and the conclusion of Barack Obama's presidency. / Master of Arts
