Strategies For Supporting Professional Growth In Early Childhood Team Members, Kristin Goetz

Graduate Teacher Education

Early childhood education (ECE) teachers, including pre-service and in-service workers, have reported the need for ongoing professional development support (Boyer, 2004; Buettner, Hye Hur, Jeon & Andrews, 2016; Brown, Cheddie, Horry, & Monk, 2017). Specific targeted support for professionalism was addressed as a retention strategy for the future of ECE (Boyer, 2004). The lack of consistent minimum qualifications for ECE teachers has contributed to a number of teachers in the field having little understanding regarding professionalism as a whole when teacher careers commence. The quality of learning and teaching in the classroom has been said to be largely determined by …

International Maritime Lecturers' Association (IMLA) 2021 Joint Conference With IMEC32, ICERS15 and INSLC21

Sustainable success has become an ever-more-important future goal in all industries but challenges arise from the advent of fourth industrial revolution and revisions of national and international regulations directly affect the shipping industry trickling down to the Maritime Education and Training Institutions (METI). Thus, a metamorphosis of standards for a maritime school like the Maritime Academy of Asia and the Pacific (MAAP) transitioning to a more tailor-fit Quality Standards is inevitable to manage the changes in educational organizations. ISO 21001:2018 has been published in oder to replace IWA 2:2007. This prompted the Academy to evolve from the traditional ISO 9001:2015 …

Nsfw: Not So Feminist Women - A Media And Cultural Studies Analysis Of Working Women In Popular Media, Josephine Schofield

Honors Projects in English and Cultural Studies

Even though gender diversity of characters has increased in television shows and films, this study hypothesized that female characters who are presented as feminist icons function as feminist backlash and perpetuate negative and harmful stereotypes. This was found to be especially true for career-focused women. Applying a cultural studies approach to reading television and film studies through a feminist lens identified the antifeminist factors that continue to cause the perpetual loop of independent women reverting to dated social roles. This research connects what audiences consume through popular media to how they perceive their female co-workers. The findings of this study …

Girlpwrd: Amplifying Silenced Voices Of Women Through Digital Storytelling, Brooke Schumann

English Theses

Drawing on data from a multi-month digital storytelling community project, this qualitative case study offers portraits of three marginalized women who re-author pivotal moments of silencing in their lives. The foundational framework blends scholarship on rhetorical silence, rhetorical listening, and semiotics of multimodal expression. These cases demonstrate how digital storytelling allows women a space to form and give voice to their silence, where they are the empowered agents of their own stories. The digital platform elevates these underrepresented narratives by creating new pathways for listening.

Nontimber Forest Products In The United States, Eric T. Jones, Rebecca J. Mclain, James Weigand

Kansas Open Books

A quiet revolution is taking place in America's forests. Once seen primarily as stands of timber, our woodlands are now prized as a rich source of a wide range of commodities, from wild mushrooms and maple sugar to hundreds of medicinal plants whose uses have only begun to be fully realized. Now as timber harvesting becomes more mechanized and requires less labor, the image of the lumberjack is being replaced by that of the forager. This book provides the first comprehensive examination of nontimber forest products (NTFPs) in the United States, illustrating their diverse importance, describing the people who harvest …

Advancements in modern medicine have greatly extended human life expectancy. However, with the onset of age-associated conditions such as Alzheimer’s disease, autoimmune disorders, and certain cancers, healthy aging is becoming an increasingly pressing issue. Blood exchanges between young and old partners demonstrate old blood can cause detrimental effect to the young animal, notably on the brain tissue. However, the complexity of blood makes it difficult to identify what role the individual factors play in the aggregate observed effect. This dissertation seeks to explore the potential effects of erythrocytes on the brain as we age. Erythrocyte morphology and rigidity changes as …

Investigation Of An Optimized Occupancy-Driven Hvac Control Strategy And Development Of A Scalable House/Grid Simulation, Kaleb Pattawi

Mechanical Engineering Master's Theses

Energy consumption in buildings is projected to increase more than 50% by 2050. Renewable energy sources are expected to increase and will help alleviate some of the energy demand; however, the intermittent nature of renewables makes it tough to effectively use energy in buildings. Various pricing schemes, including time of use electricity pricing, are used to encourage users to shift loads. Buildings need to be able to proactively react to changing energy sources and electricity prices in order to reduce over-generation of electricity and save money. This work demonstrates an optimized Heating Ventilation and Air Conditioning (HVAC) control strategy that …

Nuclear security culture is the human factor within the nuclear field which is considered a principal means to support and enhance nuclear security system. This paper presents a study of nuclear security system already established within a radiological facility considering concepts such as: deter, detect, delay, and response layers. This study …

Clabsi Prevention In The Icu-A New Approach, Shannon M. Hicks

Master's Projects and Capstones

Abstract

The Center for Disease Control and Prevention (CDC) emphasizes that the primary cause of preventable deaths and disabilities among hospitalized patients in the United States are hospital-acquired infections (HAIs). Based on the CDC surgical site infection monitoring, common infections include central line-associated bloodstream infection (CLABSI), ventilator-associated pneumonia, and catheter-associated urinary tract infections. This paper primarily focuses on the problem of CLABSI, with an aim to reduce the net occurrences of CLABSIs in the intensive care unit (ICU) through the interventional use of SecurePortIV skin adhesive during the insertion of central lines. Although few researchers have examined the implication of …

Evidence Based Repositioning Strategies To Improve Pressure Injury Rates, Ivan E. Dorsey

Master's Projects and Capstones

Pressure injuries (PI) affect approximately 1-3 million people in the United States annually, and amount to 3-11 billion dollars in yearly healthcare costs (Mondragon et al., 2021; Padula & Delarmente, 2019). In veterans who seek care, especially the elderly (>65 y/o), pressure injuries are particularly devastating because they increase hospital costs and lengthen stays (Stroupe et al., 2011). In light of these statistics, the aim of this project was to decrease PI rates in veteran patients through the implementation of evidence-based practice. This project was conducted on a medical/surgical telemetry unit with 18 beds at a Northern California hospital …

Active Membrane Energy Exchanger For Air Cooling And Dehumidification, Songhao Wu, Andrew Fix, David M. Warsinger, James E. Braun

Discovery Undergraduate Interdisciplinary Research Internship

Heating, ventilation and air conditioning (HVAC) equipment consume 35% of total building energy use in the US, among which a large share is used for cooling and dehumidification. The majority of air dehumidification systems take the conventional approach of moisture condensation removal. It requires air to be cooled below its dew point temperature and is an energy-intensive process, especially for areas with hot and humid climates. Vapor selective membrane systems are promising alternatives for air dehumidification as they do not require cooling energy for latent (humidity) heat removal. It allows water vapor transport through the membrane while blocking air. Previous …

Conceptual Design Of Two Tiltrotor Aircraft For Urban Air Mobility, Michael T. Radotich

Engineering

There has been an abundance of new and novel aircraft designs created for Urban Air Mobility (UAM) in recent years. The National Aeronautics and Space Administration (NASA) contributes to the research and development of this industry in part by applying its aircraft design tools to create conceptual designs of UAM reference vehicles. The vehicles are intended to quantify the tradeoffs and performance capabilities necessary for VTOL (vertical takeoff and landing) aircraft in the UAM design space. The reference vehicles represent a variety of configurations that seek to encompass many of the design characteristics suitable for UAM. This thesis focuses on …

Landslides In The Fairbanks North Star Borough, Alaska: Inventory Map And Tanana 440 Landslide Assessment, Jaimy A. Schwarber

Engineering

Landslides are geologic hazards that threaten human life, property, and infrastructure. Effective threat mitigation requires knowledge of where past landslides occurred. Until now, no published landslide inventory maps existed for any part of Alaska. Here we present an overview of our landslide mapping within parts of the Fairbanks North Star Borough (FNSB), Alaska and a thorough investigation and assessment of the Tanana 440 (T440) landslide. We mapped 1,679 landslides, and field-verified 51 landslides within the FNSB. These landslides vary in age, movement type, and material. Most are prehistoric, but we did observe some historic and active landslides. Observed slope failures …

Who Pays To Clean Up What A Dying Industry Leaves Behind?, Audrey Carleton

Capstones

As the birthplace of oil and gas, Pennsylvania is home to the highest number of orphaned abandoned oil and gas wells in the country — an estimated 300,000 to 500,000 dot the Keystone State, all remnants of a dying industry. These wells emit methane, a potent greenhouse gas, and have, for decades, caused alarm to hundreds of residents, documents obtained in a months-long capstone investigation show. The state is currently plugging 10 to 12 abandoned wells per year, on average, out of hundreds of thousands, in part because it has not collected enough in cleanup funds from producers to fund …

“The New Pinkertons”: Anti-Union Consultants And Surveillance Tech Thwart Organizing, Jo Constantz

Capstones

In 2020, just 6.3% of U.S. private-sector workers were union members, despite the fact that 68% of Americans approve of labor unions, the highest since 1965, and nearly half of non-union workers say they would join.

After World War II, wage growth kept pace with GDP growth, but then began to diverge in the 1970s, according to a study by the RAND Corporation. After 1975, incomes of the bottom 90% rose more slowly than the economy as a whole, while incomes of the top 10% grew faster. The declining wage growth coincided with and is closely related to a drop-off …

Phase Effects On Turbulent Transport In The Magnetic Confinement Of Plasmas For Nuclear Fusion, Dempsey Rogers

Physics

With climate change effects on the rise, the global energy infrastructure requires revision. We first provide a brief review of common energy resources as well as their safety and climate effects. We then compare and contrast nuclear fission and fusion based energy schemes. Difficulties based on the requirements of the fusion triple product, as well as the fast neutrons from the deuterium and tritium reaction are also discussed. The lack of sufficient experimental controls in enhanced confinement modes like the I-mode and the H-mode, lead to difficulties satisfying the restrictions imposed by the Greenwald density limit. These combined with several …

Barriers To Completing Degrees For Uaf Ph.D. Students, Hannah L. Whitaker

Counseling

A student faces several challenges when working towards a doctoral degree. Previous research has demonstrated that discrimination, lack of support, poor mentorship, funding issues, mental health concerns, and minority stress are barriers to degree completion. The available research also suggests that these difficulties are especially challenging for underrepresented students. Although universities are currently attempting to mitigate certain of these barriers, more can be done to understand the doctoral experience as a way of supporting students. Focus groups were conducted for this thesis to explore the barriers, strengths, and advice for others that doctoral students have at the University of Alaska …
