Cardiovascular And Stride Frequency Differences During Land And Aquatic Treadmill Walking, Jessica Burton, Sarah Duffey, Amber Hammonds, Anna Leduc, Rachel Shumate, John Coons, Ryan T. Conners

International Journal of Aquatic Research and Education

This study examined heart rate (HR) and stride frequency (SF) values of 30 college-aged males and females during dry-land (DL) and aquatic walking (AW). Aquatic walking trials were completed in an underwater treadmill with the water depth at waist level; the water temperature (31℃ ± 0.1℃) and room temperature (26.6℃ ± 0.1℃) were maintained at thermoneutral levels throughout the study. During each walking condition, HR and SF were recorded at treadmill speeds of 1 mph, 2 mph, and 3 mph. Participants were instructed to walk with their hands at their sides swinging as they would when walking on dry-land unless …


Features Of Acceleration And Angular Velocity Using Thigh Imus During Walking In Water, Koichi Kaneda, Yuji Ohgi, Mark Mckean, Brendan Burkett May 2020

Features Of Acceleration And Angular Velocity Using Thigh Imus During Walking In Water, Koichi Kaneda, Yuji Ohgi, Mark Mckean, Brendan Burkett

International Journal of Aquatic Research and Education

Ten participants were assessed while walking in water and on land with wearable inertial measurement units (IMUs) attached to the right thigh. Longitudinal acceleration, anterior-posterior acceleration, and frontal axis angular velocity were measured at 100 Hz, matched with video analysis sampled at 25 Hz during the walking trials. The longitudinal acceleration showed almost 1 g from initial heel contact to 70% of one cycle, and the anterior-posterior acceleration showed a sinusoidal pattern, synchronizing the approximate posture of the thigh in water. The frontal axis angular velocity fluctuated less while walking in water compared with on land, because thigh motion speed …

Other studies have examined how ventilation rates, combined with the presence of pollutant sources, can affect productivity. These studies provide evidence that increased ventilation, including increases above common guidance levels such as ASHRAE’s ventilation standards, improve occupant productivity. Increased occupant control over ventilation has also been shown to improve productivity. Higher indoor carbon dioxide (CO2) levels have been directly associated with impaired work performance and increased health symptoms. Historically, it was believed that these associations exist only because higher indoor CO2 concentrations, resulting from lower outdoor air ventilation rates, are also correlated with higher levels of other indoor-generated pollutants that …

La Habana: A History Of Society, Livelihood, Movement, And Land Use On The Iquitos-Nauta Highway, Katie Brown

Undergraduate Honors Theses

With increasing infrastructural projects and land titling in the Peruvian Amazon, many changes are occurring within small roadside communities. In this case study, we investigate how these changes impact livelihoods, land use, travel patterns, and social relations within the broader concepts of development, privatization of land, and commodification of nature. Specifically we focus on the caserío La Habana situated on the Iquitos-Nauta highway in the Loreto region of Peru. Semi-formal interviews and ethnographic methods were conducted to gather information on social organization, history of the community, land use practices, migration patterns, opinions on the road, and livelihood strategies. After data …

The Ocean Lifeguard Intervention Continuum: A Cognitive Aid For Surf Lifeguard Education, William A. Koon, Ryan M. Gates, Shane Scoggins, Paul Andrus, Jack A. Futoran

International Journal of Aquatic Research and Education

Ocean lifeguards are constantly engaged in beach risk analysis, required to efficiently evaluate a variety of environmental and other factors quickly in order to triage and prioritize who needs help. Teaching these skills is a challenge for introductory training programs. We sought to improve new lifeguards’ understanding of the interaction of various risk components in the beach environment and aid decision-making related to when a lifeguard should intervene in a situation. We developed a two-part cognitive aid for introductory ocean lifeguard education depicting individual and interacting elements of a beach goer’s risk of drowning or injury and the process by …

Kids Don’T Float…And Their Parents Don’T Either: Using A Family-Centered Approach In Alaska’S Kids Don’T Float Program, Michelle E. E. Bauer, Audrey R. Giles, Justina Marianayagam, Kelli M. Toth

International Journal of Aquatic Research and Education

The goal of this experiential report is to outline the adoption of a family-centered Kids Don’t Float approach. We conducted a critical synthesis of information to reflect the expansion of the Kids Don’t Float program into a more family-centered approach. The critical synthesis provided insights into why we should adopt this approach, how it was implemented, and how it influenced drowning incidents compared to the previously used child-centered approach. The adoption of a family-centered approach may contribute to reducing drowning incidents by targeting parents, providing safety information to families, and promoting parental modelling of life jackets. Program evaluators and water …

International Journal of Aquatic Research and Education

Drowning continues to be a major cause of death for children, especially among minority groups. USA Swimming commissioned studies in 2008 and 2010 to look at swimming ability or inability, an associated drowning variable. The 2010 study showed alarming high percentages regarding insufficient swimming skill for many demographic groups. The current study’s purpose was to provide further analysis of variables which emerged from 2010 study and how these variables are affecting all US populations. Focus group interviews accomplished in three regionally diverse US cities asked participants (3=fathers; 12=mothers) about their personal history with swimming, perceptions concerning swimming in general, and …

Workforce Development In A Post-Covid World: A Grassroots Approach, Cheryl A. Burkhart-Kriesel, Kristina Bayton, Samantha Guenther, Blayne Sharpe

Cornhusker Economics

As the world slowly emerges from COVID 19 both the virus and the lingering effects on the economy will be in the spotlight. There is a real urgency to get businesses up and running and employees working again. Some businesses may be able to "flip a switch" and up to speed while other may need to ramp up more slowly and will only be able to "turn up the dial." In both situations, there are implications for the local workforce and for the community.

Boating-related incidents are responsible for a significant number of the drowning fatalities that occur within Indigenous communities in New Zealand, Australia, the USA, and Canada. The aim of this paper was to identify promising practices for boating safety initiatives that target Indigenous peoples within these countries and evaluate past and ongoing boating safety initiatives delivered to/with Indigenous peoples within these countries to suggest the ways in which they – or programs that follow them - may be more effective. Based upon evidence from previous research, boating safety initiatives that target Indigenous peoples in New Zealand, Australia, the USA, and Canada …


Mental Associations And Music Therapy: Including The History Of Associationism And The Neurology Of Associations, Dianna Rose May 2020

Mental Associations And Music Therapy: Including The History Of Associationism And The Neurology Of Associations, Dianna Rose

Expressive Therapies Capstone Theses

Associations are formed in our minds based upon three elements: sensory experience, emotions, and memories. These associations, unique to each individual, dictate thoughts, beliefs, behaviors, and actions. Some are necessary and supportive, while others can be maladaptive. Established associations can be changed, and new associations can be formed, to align with a client’s goals. The literature presents a strong history of associationism, as well as a body of research that demonstrates the neurological processes of how mental associations are formed. There are also studies showing how music activates the brain. However, there is a lack of research which draws direct …

Swimming Pool Environment And Respiratory Health Issues Experienced By Masters Swimmers: Results From A Literature Review And Survey Of United States Masters Swimming Clubs, Jody C. Gan, Julia Snegg, William Harder

International Journal of Aquatic Research and Education

After three members of a Masters adult swim club died of lung cancer, both a literature review and survey were conducted with representatives from 746 United States Masters Swimming clubs to explore a possible relationship between swimming and cancers of the respiratory tract. Six other clubs reported known cancers of the respiratory tract among club members, but none of the other 740 clubs reported a similar cluster of lung cancer. More clubs reported cases of chronic respiratory infections and widespread complaints about air quality. While no studies exploring a relationship between swimming and lung cancer could be found in the …


Transdiagnostic Multimodal Neural Correlates Of Psychosis Dimensions, Dov Bernard Lerman-Sinkoff May 2020

Transdiagnostic Multimodal Neural Correlates Of Psychosis Dimensions, Dov Bernard Lerman-Sinkoff

McKelvey School of Engineering Graduate Student Theses & Dissertations

Psychosis refers to a debilitating set of symptoms that impacts individuals, their communities, and society at large. Current psychiatric nosology treats psychosis as a categorical construct. However, recent evidence suggests that a dimensional approach that cuts across extant nosological boundaries may more accurately represent the underlying phenomena contributing to dysfunction in psychosis. One putative domain of transdiagnostic variation is cognitive control, a construct that refers to the set of functions that enable and support goal-directed behavior and regulation of one’s thoughts and actions. Previous analyses in both healthy individuals and individuals with psychosis have led to a number of findings …


Editorial, Your Null Hypothesis Must Be False: Test It Anyway, Frank Corotto May 2020

Editorial, Your Null Hypothesis Must Be False: Test It Anyway, Frank Corotto

Georgia Journal of Science

A historical criticism of null hypothesis testing is that a null hypothesis cannot be correct in the first place. The reason that many nulls cannot be correct is that what makes a null hypothesis a null hypothesis is its infinite precision. Only an infinitely precise hypothesis can be used to generate an infinitely precise prediction, such as t will be zero. It is around that infinitely precise prediction that we would construct a probability density function. If you are thinking, I just want to know if the difference is significant, and if you mean important, a null …


Examining Minority Youth Swimmers’ Versus Non-Swimmers’ Perceptions Of Swimming Involvement, Timothy M. Dasinger, Laura L. Brown, Ashton J. Sawyers May 2020

Examining Minority Youth Swimmers’ Versus Non-Swimmers’ Perceptions Of Swimming Involvement, Timothy M. Dasinger, Laura L. Brown, Ashton J. Sawyers

International Journal of Aquatic Research and Education

Drowning is one of the leading causes of death in youth, especially among minority populations (Gilchrest & Parker, 2014). According to the World Health Organization (2014), every hour of every day approximately 42 people lose their lives to drowning. Additionally, African-Americans are 14 times more likely to drown in a pool than other racial or ethnic group members (Waller & Norwood, 2011). The purpose of this study was to examine survey results between swimming and non-swimming minority youth participants. Forty African American students between the ages of 5-17 from an after-school program completed the Swimming Involvement Survey. Results indicated that …


Parental Perceptions Of Water Safety Among Children With Autism Spectrum Disorders, Amanda Casey Ph.D., Jennifer Blok, Katherine Vaughan, William O'Dwyer May 2020

Parental Perceptions Of Water Safety Among Children With Autism Spectrum Disorders, Amanda Casey Ph.D., Jennifer Blok, Katherine Vaughan, William O'Dwyer

International Journal of Aquatic Research and Education

Children with autism spectrum disorders (ASD) are twice as likely to die from unintentional drowning compared to same-age children without ASD emphasizing the importance of water-safety skills and knowledge. Yet little research has been published on perceptions of water safety for this population. The objective of the study was to investigate parental perceptions of water safety amongst children with ASD. An online questionnaire focusing on parental perceptions of water safety was distributed to parents of children with ASD associated with autism support groups across Canada. Forty-nine parents completed the self-report questionnaire with items related to demographics, swimming proficiency and lessons, …

Fossil hominin footprints preserve data on a remarkably short time scale compared to most other fossil evidence, offering snapshots of organisms in their immediate ecological and behavioral contexts. Here, we report on our excavations and analyses of more than 400 Late Pleistocene human footprints from Engare Sero, Tanzania. The site represents the largest assemblage of footprints currently known from the human fossil record in Africa. Speed estimates show that the trackways reflect both walking and running behaviors. Estimates of group composition suggest that these footprints were made by a mixed-sex and mixed-age group, but one that consisted of mostly adult …


Investigating The Efficacy Of Dna Damage With Bleach In Forensic Laboratories And At Crime Scenes, Alyssa Tuccinardi May 2020

Investigating The Efficacy Of Dna Damage With Bleach In Forensic Laboratories And At Crime Scenes, Alyssa Tuccinardi

Honors Theses

Household/commercial bleach (6% NaOCl, sodium hypochlorite) degrades DNA through oxidative damage, production of chlorinated base products, and cleavage of DNA strands (breaking it into smaller and smaller fragments). The presence of these lesions significantly impacts the ability to generate a full genetic profile from an evidentiary sample. In fact, knowledge of the damaging effect of bleach on DNA is the basis for its use in forensic laboratories to clean workbenches and prevent cross-contamination of samples between cases. Additionally, bleach is used intentionally by criminals to clean up crime scenes and destroy DNA evidence. A previous study demonstrated that bleach has …
