This study examines three soil classification systems - Buganda, World Reference Base, and US Soil Taxonomy - in order to evaluate their relative strengths and feasibility for making linkages between them. Nine field sites and 16 pedons were considered across the soil landscapes of the Buganda catena. Each identified field pedon diagnostic horizons and characteristics were described and their soils analyzed using standard pedological techniques and measurements. To document the indigenous use of the Buganda classification system, interviews and discussions were held with farmer groups and local extension specialists. Using this local expertise, five local soil units were identified. We also identified ...


Influence Of Forage Diversity And Condensed Tannins On Livestock Foraging Behavior, Production And Environmental Impact, Sebastian P. Lagrange Aug 2020

Influence Of Forage Diversity And Condensed Tannins On Livestock Foraging Behavior, Production And Environmental Impact, Sebastian P. Lagrange

All Graduate Theses and Dissertations

Eating a combination of forages with different chemistries (i.e., nutrients, beneficial compounds such as tannins) may enhance ruminant nutrition and reduce environmental impacts relative to eating single forages. I explored the influence of offering sheep and cattle all possible combinations of tanniferous (i.e., plants with tannins; birdsfoot trefoil, sainfoin) and non-tanniferous legumes (i.e., plants without tannins; alfalfa) or their monocultures on animal performance, behavior, and methane and nitrogen (N) emissions. Offering choices among these legumes to penned sheep improved intake and diet digestibility relative to feeding monocultures. Mixtures selected by sheep were better digested than mixtures containing ...


The Effects Of Self-Esteem And Motivation On Cognitive Control, Andrea Benavides Jun 2020

The Effects Of Self-Esteem And Motivation On Cognitive Control, Andrea Benavides

All Dissertations, Theses, and Capstone Projects

Cognitive control describes a set of mechanisms that guide behavior towards a goal (Cohen, 2017). The successful execution of cognitive control is essential for effective learning, information processing, problem solving, and academic achievement (Visu-Petra et al., 2011). The Expected Value of Control framework (EVC; Shenhav et al., 2013) suggests that control carries an inherent cost, which is weighed against the potential benefits of expending it. This cost-benefit analysis determines the direction and intensity that a goal is pursued. Importantly, motivation plays a role in this cost-benefit analysis and may function as the factor that offsets the cost of control expenditure ...


An Investigation Of Athletic Buoyancy In Adult Recreational And Sport Club Athletes, Jackie Rae Victoriano Calhoun May 2020

An Investigation Of Athletic Buoyancy In Adult Recreational And Sport Club Athletes, Jackie Rae Victoriano Calhoun

LSU Doctoral Dissertations

Athletic buoyancy is the ability of an athlete to effectively handle the daily setbacks and challenges they face during training and competition. Although buoyancy has received ample research in the academic domain, a dearth of information exists regarding buoyancy in the athletic domain. Therefore, the overall purpose of this dissertation was to investigate athletic buoyancy’s independent contribution to sport psychology while also exploring antecedents and outcomes in adult athletes.

Study 1 compared athletic buoyancy to other cognate constructs, or similar constructs, to determine their conceptual boundaries. A one-time, online questionnaire was distributed to 294 recreational athletes (M age = 42 ...

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 ...

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 ...

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 ...

Based upon evidence from previous research, boating safety initiatives that target Indigenous peoples in New Zealand, Australia, the USA, and Canada should ...


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 ...

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 ...


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

Editorial, Your Null Hypothesis Must Be False: Test It Anyway To Determine Direction, 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 hypothesis test will ...

The Partial Immersion Aquatic Approach Using Adjustable Weight Bearing To Improve Posture And Sitting Balance Adaptation For Children With Severe Cerebral Palsy, Niv Shelef May 2020

The Partial Immersion Aquatic Approach Using Adjustable Weight Bearing To Improve Posture And Sitting Balance Adaptation For Children With Severe Cerebral Palsy, Niv Shelef

International Journal of Aquatic Research and Education

The innovative ‟Partial Immersion” Aquatic Therapy Approach was developed to enhance balance and posture during sitting adaptation for children with severe cerebral palsy who exhibit deficiency in those skills on land. Stable balance during sitting posture is one of the preconditions for hands function in activities of daily living. Aquatic skills learned during aquatic therapy were then transferred to a land environment. Therapy included the use of a treatment chair that enabled adjustable weight bearing in a series of 30 mm steps. A mixed-methods design employing a multiple case study approach (n=5) including quantitative and qualitative methods investigated the ...

Veridical And False Memory Performance As A Function Of The Timing Of High-Intensity Acute Exercise, Claire Sanderson May 2020

Veridical And False Memory Performance As A Function Of The Timing Of High-Intensity Acute Exercise, Claire Sanderson

Honors Theses

Background: Our recent experimental work demonstrated that high-intensity acute exercise improved veridical (true) memories and also increased the rate of false memories. The present experiment was designed to re-evaluate these effects for replication purposes. We also extend this literature by evaluating whether these effects are influenced by the timing of acute exercise. Methods: The sample included young adults (N=37; Mage = 21.16 years). We employed a three-condition, within-group, counterbalanced controlled design, consisting of two exercise conditions and a control condition. The exercise conditions involved a 15-minute bout of high-intensity acute exercise. These conditions included the bout of exercise ...

Swim Instruction For Individuals With Developmental Coordination Disorder, Susan J. Grosse May 2020

Swim Instruction For Individuals With Developmental Coordination Disorder, Susan J. Grosse

International Journal of Aquatic Research and Education

Almost every swim teacher has encountered an individual who had difficulty learning to swim, whose movements appeared dissimilar from peers, or who needed to repeat swim course instructional levels many times. That individual might have had difficulty with sport activities, handwriting, and been clumsy in gross and fine motor tasks. Difficulty with coordination and control of movement may suggest a diagnosis of developmental coordination disorder (DCD). Individuals experiencing DCD may feel left out, inadequate, unhappy, frustrated, and embarrassed by his or her ineptness. These feelings may result in an individual withdrawing or refusing to join in and participate in physical ...

The purpose of this article is to examine the barriers to specialized staff training in aquatics for individuals with disabilities, to suggest necessary staff training content, and to propose topics for further research in the area of staff training. Seeking development of quality staff training programs for those working in aquatics for individuals with disabilities is the quest.


Understanding Null Hypothesis Tests, And Their Wise Use, Frank Corotto May 2020

Understanding Null Hypothesis Tests, And Their Wise Use, Frank Corotto

Faculty Publications

Few students sitting in their introductory statistics class learn that they are being taught the product of a misguided effort to combine two methods of inference into one. Few students learn that many think the method they are being taught should be banned. In Understanding Null Hypothesis Tests, and Their Wise Use, I emphasize Ronald Fisher’s approach to null hypothesis testing. Fisher’s method is simple, intuitive, thoughtful, and pure. If we follow Fisher’s example, all the criticisms of null hypothesis tests melt away. Fisher on a good day. Do you collect data and then ask a friend ...

Safe Sleep: Developmental Implications For Hospitalized Infants, Katherine Kohlsaat May 2020

Safe Sleep: Developmental Implications For Hospitalized Infants, Katherine Kohlsaat

Senior Honors Projects

The rate at which an infant develops both physically and cognitively is significant during sleep, as this is the time when the entire body can dedicate its efforts to this cause. Parents of healthy infants follow the guidelines set by the American Academy of Pediatrics (AAP) relating to safe sleep, and since their introduction in 1992, the rate of Sudden Infant Death Syndrome (SIDS) has decreased by 40% (Center for Disease Control and Prevention, 2016). However, if an infant has been hospitalized since birth due to necessary invasive procedures such as open-heart surgery, these protocols cannot be initially implemented. Common ...
