Summer 1937: A Second American Team Competes “Down Under”, John W. Lundin

Works by Local Authors

During the summer of 1937, two American ski teams competed outside the U.S.  One team raced in Chile in the first Pan-American Skiing Championship, a competition that lasted until 1950, that pitted the “Esquiadores Yanquis,” an officially sanctioned U.S. F.I.S. ski team, against South America’s best skiers.  See my article, “Pan American Skiing Championships,” Skiing History, November-December 2023.  That team consisted of Seattle’s Don Fraser and five members of the Dartmouth ski team, three of whom were on the 1936 Olympic team - Fraser, Warren Chivers and Ted Hunter.

The Impact Of Reported Antibiotic Allergy In Paediatric Care And Antimicrobial Stewardship, Annabelle Arnold

Theses: Doctorates and Masters

Antimicrobial resistance is rising while new drug development declines, making antimicrobial stewardship crucial for optimizing use, preventing resistance, and improving patient outcomes. Antibiotics are vital for bacterial infections, but overuse and inappropriate prescribing have contributed to resistance. Although 5-35% of the global population reports β-lactam allergies, over 90% of reports are inaccurate. Adults have the highest prevalence; however, these labels are often acquired in childhood, with a notable increase among children recently. Unverified allergy labels hinder antimicrobial stewardship, leading to longer hospital stays, alternative prescribing, and a higher risk of adverse events.

The Development, Implementation And Evaluation Of A Novel Intervention For Delirium Prevention And Management In An Adult Intensive Care Unit: A Mixed Methods Study, Gideon Ugochukwu Johnson

Theses: Doctorates and Masters

Background: Delirium is a prevalent acute brain dysfunction in patients within intensive care units. Delirium is marked by a fluctuating mental state, inattention, and altered consciousness. This condition affects a substantial proportion of patients in intensive care units, and which leads to increased mortality, severe physiological and psychological consequences, and a significant economic burden on healthcare systems. Despite the evidence that supports the use of non-pharmacological interventions to prevent or minimise the impact of delirium such as orientation, sensory stimulation, early mobilisation, and family involvement, their implementation in intensive care units remains inconsistent. The involvement of family members in the …

Bridging The Gap: Strategies To Improve Hpv Vaccination Uptake, Stephanie Ramsey

Doctor of Nursing Practice Projects

The human papillomavirus (HPV) vaccination is approved by the United States (US) Food and Drug Administration (FDA) for individuals beginning at age 9. Evidence shows that HPV vaccination uptake is lower than other vaccinations offered in the early adolescent/adolescent age group. Healthy People 2030 set forth a goal that 80% of adolescents ages 13-15 will have HPV vaccine series completion by 2030. Research has shown that provider recommendation for the HPV vaccine is one of the reasons adolescents, or parents of adolescents, have chosen to initiate and complete the HPV vaccination. Studies have shown that providers who have been educated …

Remodeling Breastfeeding Education, Rhonda Coffey

Doctor of Nursing Practice Projects

Mothers face important decisions regarding how to feed their infants, and successful breastfeeding requires commitment, support, and education. The numerous health benefits of breastfeeding for both mothers and infants are well-documented throughout the literature, and experts recommend exclusive breastfeeding for the first year of life. Healthcare teams play a crucial role in supporting breastfeeding success by providing education, guidance, and troubleshooting assistance when complications arise. Reassurance from healthcare providers can also influence mothers' overall experiences with breastfeeding. The facility where participants deliver assists most mothers in initiating breastfeeding within 1 to 2 hours after delivery, with approximately 75% meeting this …

Implementing A Strategic Reporting Model Among Public Health Nurse Consultants To Increase Communication, Heather Willis

Doctor of Nursing Practice Projects

Public health has seen a drastic amount of turnover post-pandemic. There was an estimated 44% turnover rate for public health registered nurses, with a vacancy rate that doubled from 12.7% in March 2020 to 23.2% in July 2022 (Skinner, 2022). With this high turnover rate, many nurses are new to North Carolina (NC) public health departments and health districts. Public Health Nurse Consultants (PHNCs) are expected to train and guide these new nursing staff members. With the turnovers continuing at the local health departments (LHDs), new nurses are not given the recommended training because of communication breakdowns. This project helped …

Economic Material For Large-Scale H2 Storage And H2-Co2 Separation, Hussein R. Abid, Alireza Keshavarz, Header Jaffer, Basim K. Nile, Stefan Iglauer

Research outputs 2022 to 2026

Hydrogen is a clean fuel that can potentially completely decarbonize the energy supply chain and mitigate global warming. Hydrogen – a highly volatile gas – however, needs to be separated from CO2 during H2 production, and also from cushion gas in H2 geo-storage projects; in addition, large-scale H2 storage is a key obstacle. We thus tested and chemically upgraded common sub-bituminous coal as a material for H2-CO2 separation and H2 storage. The coal adsorbed significant amounts of H2 and CO2 and demonstrated an excellent H2-CO2 separation efficiency if chemically modified. The work presented here thus provides fundamental data required for …

Consequences Of Group-Based Misperceptions Of Climate Concern For Efficacy And Action, Zoe Leviston, Tanvi Nangrani, Samantha K. Stanley, Iain Walker

Research outputs 2022 to 2026

People tend to underestimate others’ environmental values, including when judging the values of minority-status groups. Using a large national sample (N = 5110), we test whether these misperceptions extend to concern about climate change in Australia, and differ depending on immigrant status, ethnicity, and where one is located (i.e., in or outside capital cities). We also examine the consequences of misperceptions for self-efficacy and pro-environmental behaviour. We find personal climate concern is high, but perceptions of others’ concern is lower. Immigrants and Australian-born participants have similarly high concern, but both groups underestimate how concerned immigrants are. Southern-Central-Asian identifiers are the …

Love Bites? Pre-Copulatory Behaviours Of Whale Sharks (Rhincodon Typus) At Ningaloo Reef, Western Australia, Christine Barry, Emily Lester, Micheal P. Doane, Luciana C. Ferreira, Michele Thums, Adrian C. Gleiss, Mark G. Meekan

Research outputs 2022 to 2026

Very little is known about the reproductive behaviours of whale sharks (Rhincodon typus). Here, we describe field observations of courtship behaviour by a whale shark at Ningaloo Reef, Western Australia. We witnessed and recorded following and biting behaviours by a sexually mature male of a smaller female. Following and biting are common events during courtship and copulation of other species of elasmobranchs. Our observations are consistent with earlier reports of courting behaviours in whale sharks provided by fishers, the pilot of a light plane and observations of courtship by a sexually mature male towards females held in aquaria.

Envisaging A Thriving Future: The Integration Of Positive Psychology Into Brief Psychotherapy And Family Therapy Practice, Richard Lakeman
