dissertationIn light of rampant body shame, disordered eating, physical inactivity, and widespread misunderstanding of what constitutes a healthy body, it is crucial to identify mechanisms by which women can resist distorted health discourse and redefine health for themselves outside of appearance-oriented ideals. Through following a group of 42 women ages 18-35 as they engaged in a health and media literacy curriculum developed for this study, and by using critical feminist methods to analyze participants' responses to open-ended surveys before, during, and 2 weeks after completing the curriculum, this study seeks to identify effective means for resisting appearance-focused health ideals. Through the development of a practical and accessible healthy media literacy curriculum and analysis of participants' self-reported beliefs and behaviors throughout the process, this project contributes praxis-oriented research to assist scholars, health educators, and individual women in cultivating and promoting resistance to distorted health discourse. The findings of this study also suggest that women who engage with a healthy media curriculum can develop and cultivate strategies to resist distorted health discourse by writing body image narratives that bear witness to their own lived experiences

Perceptions of Doctoral Students Regarding Factors Contributing to Student Success

This third and final phase of a sequential exploratory mixed methoddesign sought to investigate doctoral student perspectives regardingsupport services that impede or assist in the completion of an Ed.D.program at a small, northeast university. Qualitative methods includedindividual interviews and qualitative reflections to probe studentperceptions regarding support program improvements, using their\u27stories\u27 to provide rich, descriptive details. Students emphasized theneed for better pre-enrollment preparation, a comprehensive orientationand advising program, and ongoing academic support services includingwriting assistance, research skills development, and networking andmentoring. Tinto\u27s (1987) integration theory provides the framework forthis study, using his six transformative dimensions for growth anddevelopment to interpret the findings

Investigating Player Selection within UK Academy Soccer: The Application of Objective and Subjective Assessments in Detecting Talent

Talent selection and development in academy soccer is highly dependent on coach intuition. Given such reliance upon subjective inputs, a greater understanding towards the utility of coach intuition may prove invaluable. The present study investigated coach agreement, the associations between subjective and objective outcomes and prominent traits highlighted within player (de)selection. Academy players (n = 45, age = 14 ± 2yrs) and coaches (n = 10, age = 31 ± 5yrs) were recruited from a professional soccer academy. Objective assessments included tactical and psychological surveys, physical assessments (linear sprints, change of direction and jumping tasks) and performance analysis (performance assessment for team sports). Coach subjective player gradings were collected using a visual analogue scale aligned to the objective assessments. Lead and assistant coaches demonstrated poor-to-moderate agreements in perceived player skills (ICC = 0.48 to 0.76) and fair to almost perfect agreement in player (de)selection (ICC= 0.23-1.00, P <.001 to .26). However, coach agreement reduced as players aged. Likewise, a maturation related bias was present whereby biologically older players were selected over their lesser mature players. Moreover, coach intuition demonstrated a strong predictive capability to select players, whilst the study was incapable of distinguishing exclusive traits related to selection outcome

Materials Characterization at Utah State University: Facilities and Knowledgebase of Electronic Properties of Materials Applicable to Spacecraft Charging

In an effort to improve the reliability and versatility of spacecraft charging models designed to assist spacecraft designers in accommodating and mitigating the harmful effects of charging on spacecraft, the NASA Space Environments and Effects (SEE) Program has funded development of facilities at Utah State University for the measurement of the electronic properties of both conducting and insulating spacecraft materials. We present here an overview of our instrumentation and capabilities, which are particularly well suited to study electron emission as related to spacecraft charging. These measurements include electron-induced secondary and backscattered yields, spectra, and angular resolved measurements as a function of incident energy, species and angle, plus investigations of ion-induced electron yields, photoelectron yields, sample charging and dielectric breakdown. Extensive surface science characterization capabilities are also available to fully characterize the samples in situ. Our measurements for a wide array of conducting and insulating spacecraft materials have been incorporated into the SEE Charge Collector Knowledgebase as a Database of Electronic Properties of Materials Applicable to Spacecraft Charging. This Database provides an extensive compilation of electronic properties, together with parameterization of these properties in a format that can be easily used with existing spacecraft charging engineering tools and with next generation plasma, charging, and radiation models. Tabulated properties in the Database include: electron-induced secondary electron yield, backscattered yield and emitted electron spectra; He, Ar and Xe ion-induced electron yields and emitted electron spectra; photoyield and solar emittance spectra; and materials characterization including reflectivity, dielectric constant, resistivity, arcing, optical microscopy images, scanning electron micrographs, scanning tunneling microscopy images, and Auger electron spectra. Further details of the instrumentation used for insulator measurements and representative measurements of insulating spacecraft materials are provided in other Spacecraft Charging Conference presentations. The NASA Space Environments and Effects Program, the Air Force Office of Scientific Research, the Boeing Corporation, NASA Graduate Research Fellowships, and the NASA Rocky Mountain Space Grant Consortium have provided support
