Comparison Of Mortality Data From Nebraska’S Rural & Metropolitan Health Districts, Claire Figi

Theses/Capstones/Creative Projects

As there has been minimal research done on the correlation between communities identified as rural or metropolitan and their mortality rates, this research aims to provide baseline evidence that mortality rates associated with non-infectious and infectious diseases are connected to an area’s rural or metropolitan classification. This study analyzed public data from the Nebraska Department of Health and Human Services and the Center for Disease Control to compare mortality rates related to the top two causes of death in both rural and metropolitan health districts of the state of Nebraska, United States. This data was then compared to mortality rates …

Altering The Expression Of Artemisinin Through Osmotic Manipulation, Tyler Friesen

Theses/Capstones/Creative Projects

Artemisinin is an anti-malarial drug used in combination therapy to treat all malarial parasites in the blood stage. The expression of artemisinin within the plant Artemisia annua is only 1% of the dry weight. Methods for increasing the level of artemisinin within the plant were proposed. This paper looks into finding homologous enzymes across multiple species in order to find species where genetic manipulations will be useful. The second part of this paper looks at the use of osmotic stress to increase the reactive oxygen species in order to increase the amount of artemisinin within the plant. The database portion …

Impact Of Adiposity On Postural Control At The Onset Of Sitting, Danae M. Dinkel, Anastasia Kyvelidou, Ben Senderling, Kailey Snyder, Jung-Min Lee

Research Presentations

Little research has examined the impact of infant adiposity on the quality of gross motor behavior, especially in sitting through measuring postural control. Therefore, the purpose of this study was to examine the impact of adiposity as measured by skinfold thickness (SFT) on postural control at the onset of sitting in typically developing infants. Nineteen infants (n=8 high SFT, n=11 lower SFT) participated in a pilot study examining the relationship between infant physical activity and postural control. High SFT was classified as having a subscapular and triceps measurement in the 85th percentile or above according to the WHO age and …

Impact Of Adiposity On Physical Activity Levels Of Young Infants, Kailey Snyder, Danae M. Dinkel, Jung-Min Lee, Anastasia Kyvelidou

Research Presentations

Studies suggest that infant adiposity may delay the development of motor skills such as sitting.1-3 However, the role of physical activity (PA) in the development of motor skills during the first year of life has been understudied and little is known about the amount of PA needed for normal growth and development in infants.4,5

PURPOSE: The purpose of this study was to examine the impact of adiposity as measured by subscapular skinfold thickness (SFT) on PA of typically developing infants at three months of age (visit 1), onset of sitting (visit 2) (M=5 months, 8 days), and one month post …

Perceptions Of Infant Physical Activity And Weight: A Parents Perspective, Danae M. Dinkel, Anastasia Kyvelidou, Jung-Min Lee, Kailey Snyder

Research Presentations

Background: Approximately 10% of infants and toddlers in the U.S. are already overweight. One modifiable factor that may impact weight is physical activity (PA). Historically, society has thought that infants (0-1 year of age) are “active enough” and not in need of efforts to promote PA to expend energy. However, increases in technology have led to less PA in children of all ages. There is a vital need to improve knowledge about factors that may impact the promotion of PA to infants. Since parents are the primary caregivers for infants, their beliefs about weight and PA may influence the amount …

Influence And Support For Childhood Cancer Survivor’S Participation In Physical Activity, Ava Coughlin

Research Presentations

Purpose: The purpose of this study was to explore childhood cancer survivor’s social support for physical activity (PA) during and after cancer treatment as well as the type of support they desired.

Methods: Semi-structured qualitative interviews were conducted with childhood cancer survivors (n=7). Data were analyzed through the process of immersion/crystallization.

Results: All survivors noted a decrease in PA during treatment. All survivors expressed a desire to return back to “normal” PA levels after treatment. Survivors reported they received general support from parents, physicians, and peers at cancer oncology camps. Most survivors expressed a desire to develop support networks with …

Alumni Collegiate Student-Athletes’ Wellness After Sport, Shane Warehime, Danae M. Dinkel, Abby Bjornson, Ashley J. Blount

Research Presentations

College student-athletes (may be more likely to experience difficulty transitioning from college than non-athletes, which could lead to decreased levels of overall wellness.

Purpose: The purpose of this study was to explore the wellness of alumni SA who recently transitioned from college.

Methods: Semi-structured interviews with former SA (n=12) were administered at a university in the Midwest. Interview questions were based on the Indivisible Self Model’s five factors of wellness (coping, social, physical, creative, and essential). Data were analyzed using the process of immersion/crystallization.

Results: Results indicate that subjects generally experienced negative feelings at the end of their athletic career, …

Do Perceptions Of Classroom Physical Activity Breaks Vary By Size Of School District?, Tyler Patterson, Kailey Snyder, Danae M. Dinkel, Connie Schaffer, Jung-Min Lee

Research Presentations

Background: Classroom physical activity (PA) breaks offers a way for schools to increase children's PA, improve time on-task, and improve academic scores. Professional development delivery models, technology infrastructure, and opportunities for collaboration are influenced by school district size. These factors may impact teachers' perceptions of instructional issues, including PA. However, little is known on how the size of school districts may impact teachers' perceptions of classroom PA. Purpose: The purpose of this study was to explore if teachers' perceptions of classroom PA vary based on district size. Method: Sixty teachers from five school districts (1 large public, 3 medium …

Utilization Of Classroom Physical Activity Breaks, Danae M. Dinkel, Jung-Min Lee, Caitlin Golden, Connie Schaffer

Research Presentations

Historically within schools, physical education and recess periods have been utilized as the primary times for children to obtain some portion of physical activity (PA) recommendations during the school day. Due to academic pressure, opportunities for physical education and recess periods have been reduced. Fewer than 5% of schools require daily physical education and fewer than 12% require daily recess. Additional PA opportunities are needed throughout school day.

PURPOSE: The overall purpose of this study was to examine teachers’ utilization of classroom PA breaks.

METHODS: 332 Elementary school teachers from five school districts in a Midwest city were …

An Exploratory Study Of Infant Physical Activity In Relation To Obesity, Danae M. Dinkel, Jung-Min Lee, Kailey Snyder, Anastasia Kyvelidou

Research Presentations

Historically, society has thought that infants (0 to 1 year of age) are “active enough” and not in need of efforts to promote physical activity (PA). However, approximately 10% of infants in the U.S. are obese and research has shown low PA is one of the risk factors for obesity in toddlers. Little research has been done to systematically compare PA levels between normal weight infants and obese/overweight infants in the first year of life. PURPOSE: The purpose of this study was to determine the level of PA in normal weight and overweight infants. METHODS: Twenty-one normal weight …

A Spatial Sirs Boolean Network Model For The Spread Of H5n1 Avian Influenza Virus Among Poultry Farms, Alexander Kasyanov, Leona Kirkland, Mihaela Teodora Matache

Mathematics Faculty Proceedings & Presentations

To predict the spread of Avian Influenza we propose a synchronous Susceptible-Infected-Recovered-Susceptible (SIRS) Boolean network of poultry farms, using probabilistic Boolean rules. Gravity models from transportation theory are used for the probability of infection of a node in one time step, taking into account farm sizes, distances be- tween farms, and mean distance travelled by birds. Basic reproduction numbers are computed analytically and numerically. The dynamics of the network are analyzed and various statistics considered such as number of infected nodes or time until eradication of the epidemic. We conclude that mostly when large farms (eventually) become infected the epidemic …
