Technological And Managerial Gaps In The Adoption Of Improved Groundnut Seed Varieties In Uganda, Neha Paliwal

Master's Theses

The international community has successfully developed improved varieties of seeds that yield high returns in the presence of drought, pests, and disease. This effort is in response to the persistent concern of food security, especially in regions that are most vulnerable to climate change. This study uses cross-sectional data from the World Bank Living Standards Measurement Survey to obtain estimates for the adoption of improved groundnut varieties (IGVs) in Uganda as well as gaps in farmer managerial capacity (alternatively known as technical inefficiency). To do so, this study employs an adoption logit model, in conjunction with a stochastic production frontier …

A Study Of Native Parasitoids And Rearing Diet Efficacy For The Brown Marmorated Stink Bug Halyomorpha Halys, Zachary R. Donais

Master's Theses

The brown marmorated stink bug (BMSB) Halyomorpha halys (Stål), (Hemiptera; Pentatomidae) is an insect native to Asia. It was first discovered in the United States in the mid-1990s near Allentown, Pennsylvania. It was found in Connecticut in 2008 and since then numbers have continuously grown to where the pest is becoming an agricultural problem. A study was done to detect what native parasitoids attack the BMSB. Two different parasitoids were detected along with numerous accounts of egg predation. A second study focused on the effect of rearing diets on BMSB development. Time to maturation and longevity were significantly affected by …

The Effect Of Weighted Body Armor On Close Combat Reaction Time And Core Muscle Activation 2016, Christopher Banta

Master's Theses

The purpose of this study was to measure the choice reaction time and myoelectric activity of the right and left rectus abdominus, and right and left external obliques required to initiate movement in response to a visual stimulus that signaled performance of four different closecombat movements (left or right cross and left or right dodge). Reaction time and myoelectric activity were then compared with performing the movements in response to the visual stimulus while wearing a weighted vest that simulated wearing tactical body armor. Myoelectric activity was measured as the average root mean square (RMS) of the surface electromyography (sEMG) …

Power Output And Loads On The Lumbar Vertebrae During A Power Clean 2016, Joseph Keleher

Master's Theses

The purpose of the present study was to compare the peak resultant torque, shear, and compressive forces acting at the L3/L4 junction of the lumbar vertebrae and the peak power output during 40% one repetition maximum (1RM) and 80% 1RM attempts of the power clean. It was hypothesized that performance of a power clean at 80% 1RM will result in greater peak resultant compressive force, torque and shear force at the L3/L4 junction of the lumbar spine than that of a 40% 1RM attempt. Power cleans at 80% 1RM will also result in higher maximum instantaneous power outputs than that …

Diagnoses By Gender: The Consequences Of Treatment Of The Mentally Ill In Virginia Woolf's The Waves And Mrs. Dalloway 2016, Erika Nichole Jackson

Master's Theses

“Insanity is purely a disease of the brain…The physician is now the responsible guardian of the lunatic, and must ever remain so.” Sir John Charles Bucknill (1897)

Mental illness has consistently been and continues to be a subject that is viewed as taboo by society, especially when it comes to diagnosing a patient. Instead of acknowledging a person’s actions, thoughts, and words, society continually disregards mental illness as something that is negative and to be feared. The fact that this area of medicine can be difficult and distressing makes it all the more important to continue research. It is true …

The Effect Of Descriptive Norms On Resistance Exercise Self-Efficacy In College-Aged Females 2016, Justin Kompf

Master's Theses

Resistance training is a form of physical activity that provides substantial health benefits. Despite these widespread benefits, participation in resistance training is considerably low, particularly among females. To engage in a skill-related activity such as resistance training, individuals need to have confidence in their abilities. Self-efficacy is a cognitive construct that is used to describe situation-specific self-confidence. Descriptive norms are a type of social norm that describes the behavior of others. Descriptive norms have been useful in positively changing health related behaviors. The exact mechanism of how descriptive norms alter behavior is unknown. However, it has been show in research …

Participants (n=142) completed assessments measuring their thoughts and attitudes towards …

Parenting Practices And Young Adults’ Emotional Distress: The Moderating Roles Of Family Structure And Race, Nathan Alexander Winner

Master's Theses

Authoritarian parenting practices are more common among African American families, and appear to include fewer disadvantages in regards to child outcomes compared to White/non-Hispanic families who use these same practices. Little is known about why these racial differences occur, although family structure may play a role. The present study sought to understand the role of family structure and race in moderating the effects of parenting practices on college student mental health outcomes. College students reported on the parenting practices of their caregivers, as well as their race, family structure, characteristics of their familial environment, and socioeconomic status. Levels of depression, …

Effects Of A Twelve Week Aerobic And Strength Training Intervention On Chemotherapy-Induced Peripheral Neuropathy, Sherilyn M. Sommerville

Master's Theses

Chemotherapy is one of the most effective cancer treatments to date; however, it has the potential to produce debilitating life-long side effects. Chemotherapy-induced peripheral neuropathy is a side effect caused by toxic chemotherapy agents that deteriorate the peripheral nerves of the body. Research has suggested that aerobic and strength training may be able to alleviate some of the symptoms associated with chemotherapy-induced peripheral neuropathy. Some of the benefits of both aerobic and strength training include increasing blood and nutrient flow to the peripheral nerves, which could help restore sensation and alleviate the some symptoms of chemotherapyinduced peripheral neuropathy. However, to …

Alluvial Sedimentation Associated With Logging In Low Gradient Watersheds In Desoto National Forest, Mississippi, Andrew W. Simmons

Master's Theses

Forestry and related businesses are an important factor of Mississippi’s economy, contributing between $11 and $14 billion annually (Mississippi Forestry Commission, 2006). The timber industry is not only important in Mississippi but is an important sector of the economy throughout the Gulf Coast region. While providing positive economic benefits to the region, the forestry industry can also negatively affect soil properties, hillslope stability, and increase sedimentation rates in local streams and rivers. The aim of this research is to determine if forestry removal causes an increase of soil erosion and how it affects floodplain sedimentation in the low gradient watershed …

Congruence With College Major In Light Of Cognitive Influence And Work Roles, Erica L. Mathis

Master's Theses

Using Holland’s theory, the author examined moderators that may influence students’ academic success and satisfaction while accounting for cognitive influence. Data from 233 undergraduate students was analyzed using a series of hierarchical multiple regressions. The study sought to determine if student employment and the level of interest profile elevation were significant moderators of the relationship between congruence with college major and academic major satisfaction, as well as academic major success. Uniquely, academic major success was determined through GPA and a 10-subscale self-report measure. Cognitive influences were operationalized as positive and negative thinking and accounted for in all analyses. Correlation results …

Sex-Related Alcohol Expectancies, Alcohol Consumption, And Risky Sexual Behavior Among African American College Women, Danielle P. Cottonham

Master's Theses

African American college women are experiencing sex-related negative consequences (e.g., contracting sexually transmitted diseases or human immunodeficiency virus, having an unplanned pregnancy) at disproportionate rates in comparison to Caucasian college women. Furthermore, African American college women are likely engaging in risky sexual behaviors (e.g., unprotected anal, vaginal, oral sex) that may be placing them at a greater risk for experiencing sex-related negative consequences. Research suggests that increased alcohol consumption is predictive of more risky sexual behavior among college women. Additionally, sex-related alcohol expectancies, or beliefs about the effects of alcohol on sexual behavior, are positively associated with increased alcohol consumption …

Anger And Sadness Rumination And Their Impact On Momentary Changes In Impulsivity And Pain Tolerance: Implications For The Development Of Suicide Risk, Keyne Catherine Law

Master's Theses

Recent research in suicide has called for an increased focus on factors that facilitate an individual’s transition from suicidal ideation to action (Klonsky & May, 2014). Rumination, the repetitive fixation on negative emotional material, has been associated with not only increased suicidal ideation but also a history of self-injury and suicide attempts (Morrison & O’Connor, 2008), suggesting that it may contribute to the ability to inflict lethal and non-lethal self-harm. Given that past research has found physiological differences between low (ex. sadness) and high (ex. anger) arousal negative affective states, the present thesis project sought to examine the effects of …

Fire And Fuels: Vegetation Change Over Time In The Zuni Mountains, New Mexico, Luke Wylie

Master's Theses

The Zuni Mountains are a region that has been dramatically changed by human interference. Anthropogenically, fire suppression practices have allowed a buildup of fuels and caused a change in the fire-adapted ponderosa pine ecosystem such that the new ecosystem now incorporates many fire-intolerant species. As a result, the low-severity fires that the ecosystem once depended on to regenerate the forest are much reduced, and these low-severity fires are now replaced by crown-level infernos that threaten the forest and nearby towns. In order to combat these effects, land managers are implementing fuel reduction practices and are striving to better understand the …

Attention-Deficit/Hyperactivity Disorder Symptoms As A Mediator Of The Relation Between Social Perception And Social Skills And Adaptability In Preschoolers, Brandi Michelle Ellis

Master's Theses

ADHD symptoms have been linked empirically to both social perception deficits as well as impairments in social skills and adaptability. The current study built on existing literature by examining whether social perception abilities indirectly predicted social skills and adaptability through ADHD symptoms in preschool-aged children. The sample consisted of 3- to 6-year-old children attending Head Start Programs and private preschools (N = 76). It was expected that social perception abilities would positively relate to both social skills and adaptability. It was also expected that these relations would occur indirectly through ADHD symptoms. Specifically, social perception abilities would relate negatively …

Student Perceptions Of Mentally Ill Offenders, Kimberly Nicole Rayborn

Master's Theses

Since deinstitutionalization, the responsibility for mentally ill members of society has shifted to the criminal justice system in a process of trans-institutionalization or “criminalization of mental illness” (Slate & Johnson, 2008). Though various groups have been studied to ascertain their perception of mentally ill individuals and offenders, previous research focuses largely on students of psychology, social work, and medicine. Little research has been conducted regarding the perceptions of students of criminal justice toward mental illness, despite the increasing involvement of the criminal justice system in treating and handling mentally ill individuals in the past thirty years. This exploratory research serves …

Effects Of A Brief Mindfulness Induction On Death-Related Anxiety, David Matthew Schultz

Master's Theses

Terror management theory postulates that the behavior and beliefs of individuals are influenced on some level by an underlying aversion to death. Mortality salience, the conscious awareness of one’s own impending death, creates behavioral changes in individuals compared to non-mortality salient individuals. These changes in behavior are referred to as distal and proximal defense mechanisms. Relatively little research has investigated mechanisms to buffer effects of mortality salience. Mindfulness refers to a conscious awareness and acceptance of moment-to-moment experiences. By allowing individuals to take a regulated view of difficult situations, mindfulness may attenuate the negative effects of mortality salience. The present …

Master's Theses

This paper compiles existing ideas, theories, and experiments across multiple disciplines to provide guidance for a company looking to implement an optimal RFID system in their production facility. The desire is to maximize the information received by the system while minimizing the cost. Four potential layouts of RFID antennas, two with overlapping antenna coverage and two with non-overlapping layouts, are first analyzed to understand the special coverage and the number of antennas required. The value of information is then quantified to determine whether higher coverage layouts are worth the additional costs associated with the higher number of antennas required. It …

Effects Of Intermittent Pneumatic Compression On Leg Blood Flow And Vascular Function After Spinal Cord Injury, Lena Marie Cialdella

Master's Theses

Intermittent pneumatic compression (IPC) can increase leg blood flow (BF) in able-bodied persons. Whether IPC can alter leg BF, and improve vascular function in people with SCI is currently unknown. PURPOSE: Test the hypothesis that acute IPC will increase leg BF, and improve vascular function in SCI. METHODS: Participants (n=8; injury level: T3 and below; A.S.I.A. class A-C; age: 41±17 yrs) were recruited for a 1-hour IPC session performed in one leg (experimental leg; EXP), with the other serving as a control (CON). IPC consisted of sequential, foot-to-calf compressions (4-s inflate, 16-s deflate; 3 compressions/min). Posterior-tibial artery BF (Doppler-ultrasound) was …
