Exploration Of Model-Resolution Dependence Of Forecasted Wind Hazards For Small Unmanned Aircraft System Operations, Lucas Andrew Reilly

Theses and Dissertations

Use of the small Unmanned Aircraft System (sUAS) for commercial applications is growing. Once approval is granted to conduct flights Beyond Visual Line Of Sight (BVLOS), utilization of the sUAS will accelerate. Hazards associated with sUAS flight, including weather hazards, must be understood when flying BVLOS. One of the leading weather hazards is wind. In this study, nested Weather Research and Forecasting (WRF) model simulations with horizontal grid spacings of 12 km, 4 km, 1.33 km, and 0.444 km were conducted to evaluate the impact changing resolution has on wind fields and, thus, on the forecasting of sUAS wind hazards. …

Examining College Students’ Emotions And Alcohol Usage On A College Campus: Student Chemical Assessment And Review Program (Scarp), Thomas William Solem

Theses and Dissertations

Alcohol use and abuse is an important issue amongst college students, and the totality of impacts are still misunderstood. Identification of high-risk alcohol abuse problems leads universities to intervene; however, the emotional, personal, and academic impacts of such mandated intervention programs is unclear. Helping universities understand students’ alcohol abuse challenges can aid appropriate interventions, as well as improve student well-being and academic success.

The purpose of this study is to examine the Student Chemical Assessment Review Program (SCARP), specifically to explore its impacts on student variables (university motivation, readiness/importance of confidence to change, self-esteem, guilt, shame, depression, anxiety, and resiliency) …

Case Judgments And Juror Perceptions Of The Stereotypical Defendant, Mariah Sorby

Theses and Dissertations

Stereotypes and prejudice have been shown to bias information processing and decision making. There are physical traits that are stereotypically associated with criminals, i.e. tattoos, dark skin-tone, facial untrustworthiness, Afrocentric facial features. These features have been shown to influence verdict decisions and sentencing outcomes. However, there is a paucity of research investigating the additive effects of these features while also considering individual levels of prejudice and egalitarian views. The current research aimed to investigate the effects of several combinations of features on defendant verdict, sentencing, and criminal appearance ratings, rather than assessing the features in isolation, while controlling for prejudice …

Thirteen articles published between January 2014 and December 2019 were identified from a search of two databases. Ten of these articles were further analyzed according to the Community of Inquiry (CoI) framework. …

Training And Support Of Unit Preceptors_A Literature Review Of Most Successful Tools, Corinne E. Jones

Nursing Capstones

With nurses entering the workforce in the millions, preceptors are used to educate and train preceptees in clinical settings. A knowledge-practice gap exists when preceptors are put into their roles without any training regarding how to perform their preceptor duties. While preceptor education is desired among preceptors, there are no set standards for how preceptor training is delivered or what content is included. This paper reviews current literature and synthesizes results to form general guidelines regarding how best to deliver preceptor education and concept themes to be included in preceptor education. The databases CINAHL, PsycINFO, and ERIC were searched for …

Secondary Infall In The Seyfert's Sextet: A Plausible Way Out Of The Short Crossing Time Paradox, Omar López-Cruz, Héctor Javier Ibarra-Medel, Sebastián F. Sánchez, Mark Birkinshaw, Christopher Añorve, Jorge K. Barrera-Ballesteros, Jesús Falcon-Barroso, Wayne A. Barkhouse, Juan P. Torres-Papaqui

Physics Faculty Publications

We used integral field spectroscopy from CALIFA DR3 and multiwavelength publicly available data to investigate the star formation histories of galaxies in the Seyfert's Sextet (SS; HCG 79). The galaxies H79a, H79b, H79c, and H79f have low star formation rates despite showing strong signs of interaction. By exploring their individual specific star formation histories, we identified three earlier episodes of strong star formation common to these four galaxies. We use the last two episodes as markers of the epochs when the galaxies were crossing. We suggest that after the first turnaround, initially gas-rich galaxies crossed for the first time, consuming …

Life On Holidays: Study Protocol For A 3-Year Longitudinal Study Tracking Changes In Children's Fitness And Fatness During The In-School Versus Summer Holiday Period, Amanda Watson, Carol Maher, Grant R. Tomkinson, Rebecca Golley, Francois Fraysse, Dorothea Dumuid, Hayley Lewthwaite, Tim Olds

Education, Health & Behavior Studies Faculty Publications

Background: Emerging evidence suggests that children become fatter and less fit over the summer holidays but get leaner and fitter during the in-school period. This could be due to differences in diet and time use between these distinct periods. Few studies have tracked diet and time use across the summer holidays. This study will measure rates of change in fatness and fitness of children, initially in Grade 4 (age 9 years) across three successive years and relate these changes to changes in diet and time use between in-school and summer holiday periods.

Methods: Grade 4 Children attending Australian Government, Catholic …
