Distiphallus Morphology And Its Role In Copulation Dynamics In Anastrepha Suspensa (Loew), Taylor J. Inboden

Masters Theses

Anastrepha suspensa (Diptera; Tephritidae) is an agricultural pest species causing severe economic damage and is controlled, in part, by applying knowledge of this species' reproduction (e.g., disrupting fertile copulations by SIT). During copulation, males transfer sperm as well as protein rich fluids through an aedeagus and distiphallus, which females then store in three spermathecae and one ventral receptacle. Within the female reproductive tract, the ventral receptacle and the three spermathecae are strategically separated from each other. I hypothesized males' ability to direct sperm transfer within the female reproductive tract is through the structures found in the distiphallus. Utilizing scanning electron …

The Relationship Between Resilience, Coping, And Social Media, Lillian N. Hurley

Masters Theses

This study was designed to explore relationships between measures of resilience, coping strategies, social media usage, and depression. Resilience refers to one's ability to endure and recover from adversity. Many theories about what contributes to the development resilience have been explored without a clear consensus. Taormina (2015) argued that adult personal resilience is comprised of four dimensions - determination, endurance, adapatability, and recuperability. Coping, a construct related to resilience, is the process of regulating emotions, cognition, behavior, physiological responses, and the environment in response to stressful events. Past research indicated those with poorer mental health have the tendency to use …

Energy usage trends during this period were observed using circuit-level monitoring equipment. It was determined that, at select times of the year, energy used to account for …

Loss Of Trust: The Negative Effects Of Leader Discrimination And The Mitigating Effects Of Organizational Response, Andrew Wade Pepper

Masters Theses

"This thesis focuses on how perceptions of leader discriminatory behavior influence trust in the leader and, subsequently, attitudes about the organization which the leader represents. This study builds on previous research findings by creating a 2 (discriminatory interaction) X 2 (procedural response) X 2 (distributive response) experimental design model with vignettes that focused a leader's discriminatory or non-discriminatory behaviors and how the organization responds to accusations of such behavior. Participants (N = 293) were recruited from Amazon Mechanical Turk and randomly assigned to read one of the two vignettes describing a supervisor's discriminatory or non-discriminatory behavior. After reporting perceptions shaped …

Investigation Of The Information Provided By Light Touch For Balance Improvement In Humans, Anirudh Saini

Masters Theses

"This study investigates the information provided by Light Touch (LT) in improving human postural stability without mechanical assistance. Light Touch, an interaction force with a magnitude about 1 N, is known to improve postural stability in humans during quiet standing. However, the nature of the information from LT that helped improve balance is yet unknown. In this work, we hypothesized that LT provides information about one's body kinematics. We used a haptic robot to provide modulated, measurable light interaction force on the high back haptic location of humans to provide body kinematics-dependent information through LT. Standing balance experiments were performed …

The Potential Benefits Of Using Humor To Reduce Prejudice And Violence, Ethan Radatz

Masters Theses

In the field of social psychology, there have been multiple sources of research demonstrating the proposed links between prejudice and humor. The breadth of this research appears to hold the common theme of observing how the use of negative humor can disenfranchise different outgroups, or groups that seem to be at the bottom of the social ladder (e.g. the poor, marginalized ethnic/racial groups, sex, gender, and so on). Furthermore, the concepts of prejudice, as well as humor have been rarely observed through any nonviolence framework. The present study examined any relationship between humor (affiliative, self-enhancing, aggressive, and self-defeating), nonviolence (physical …

The Role Of Contact And Empathy In Stigma Toward Individuals With Mental Illness Among Mental Health And Non-Mental Health Professionals, Quincy A. Knolhoff

Masters Theses

This study was designed to help identify the factors that predict people's stigmatized attitudes toward individuals with mental illness. Corrigan (2002) suggested that stigmatized beliefs about individuals with mental illness may be detrimental to the potential recovery of these individuals, their self-esteem, empowerment, and their integration into society. One factor that has been found to reduce this stigma is personal contact with mentally ill individuals (Corrigan et al., 2002). Additionally, research has shown that empathy and principled moral reasoning are negatively correlated with prejudice, or stigma (McFarland, 2010). The current study examined level of contact, employment in a mental health …

Social Anxiety And Problematic Drinking In College Students: Examining Potential Mediators, Carissa Gutsmiedl

Masters Theses

Social anxiety and problematic drinking are among the most prevalent disorders present in the college population. Having one or both of these disorders while in college can be detrimental to academic performance and can increase dropout rates. Social anxiety has been found to precede problematic drinking in previous research. The purpose of this study was to help determine what variables may explain this relationship (i.e., mediators). The current study tested whether emotion regulation difficulties, drinking motives, alcohol outcome expectancies, and self-discrepancy mediated the relationship between social anxiety and problematic drinking among college undergraduates (N = 135). Results indicated that emotion …

Students reflected Perry's (2010) multiplicity stage of development appropriate for this age …

Construct Validity Of The Learning-To-Learn Scales (Ltls) With A Preschool And Kindergarten Sample, Kassandra Jane Charles

Masters Theses

Learning behaviors, "observable behavior patterns that children display as they approach and undertake school learning tasks" (Yen, Konold, and McDermott, 2004, p. 159) and "the degree to which children adopt beneficial approaches to learning" (Rikoon, McDermott, & Fantuzzo, 2012, p. 273) have been shown to account for a substantial amount of variance in academic achievement and add predictive validity for future academic achievement. Prediction of academic achievement is vital when making individual decisions concerning academic placement, diagnosis, early intervention, and student selection (Yen, Konold, & McDermott, 2004). The current study assessed the concurrent criterion validity of the Learning-to-Learn Scales (LTLS) …

Digit Ratio As A Predictor Of Risk Taking And Sensation Seeking Personality Traits And Behaviors, Hanna Elizabeth Hobson

Masters Theses

Digit ratio is the difference in length between the pointer finger and the ring finger on either hand. Commonly referred to as the 2D:4D ratio, this ratio is determined prior to birth, and serves as an indicator of prenatal hormone exposure. Digit ratio has been found to correlate with fundamental personality and behavior characteristics in adulthood. Digit ratio is also thought to be a determinate of sexual orientation in both men and women, but has been debated in the literature. This study examined multiple 2D:4D relationships. Men who were found to have a more masculinized (ie. lower) digit ratio had …

Is The Relationship Between College Drinking Behaviors And Social Anxiety Mediated By Alcohol Expectancies And Traumatic Life Experiences?, Cortney Lin Kingsmill

Masters Theses

The relationship between alcohol consumption and social anxiety is difficult to understand, as there have been mixed findings in the research. In general, a positive correlation has been found between the two, with a focus on the mediating effect of alcohol outcome expectancies. Both positive expectancies and trauma have been correlated positively with social anxiety and drinking behavior. This paper reviews the literature and examines the relationship between social anxiety and alcohol consumption. A mediated model between these two variables with the mediators being alcohol expectancies and traumatic experiences was proposed, but this model did not fit the date. Specifically, …

Binge Eating Disorder: Relationship To Physical And Emotional Factors, Taylor M. Mcmillan

Masters Theses

Binge eating disorder (BED) is a new core diagnosis within the Diagnostic Statistical Manual Fifth Edition (DSM-5; APA, 2013). Because binge eating disorder is a new diagnosis, research within this area is both lacking and developing quickly. Social physique anxiety and emotion regulation have been linked previously to binge eating disorder. In contrast, there is little research on the potential link between physical activity and binge eating disorder; however, physical activity has been shown to have potential treatment benefits for binge eating. This study examined BED on a continuum and its links to physical activity, emotion regulation, and subtypes of …
