Description
Guided by Tinto’s Theory of College Student Departure, I conducted a set of five studies to identify factors that influence students’ social integration in college science active learning classes. These studies were conducted in large-enrollment college science courses and some were specifically conducted in undergraduate active learning biology courses. Using qualitative and quantitative methodologies, I identified how students’ identities, such as their gender and LGBTQIA identity, and students’ perceptions of their own intelligence influence their experience in active learning science classes and consequently their social integration in college. I also determined factors of active learning classrooms and instructor behaviors that can affect whether students experience positive or negative social integration in the context of active learning. I found that students’ hidden identities, such as the LGBTQIA identity, are more relevant in active learning classes where students work together and that the increased relevance of one’s identity can have a positive and negative impact on their social integration. I also found that students’ identities can predict their academic self-concept, or their perception of their intelligence as it compares to others’ intelligence in biology, which in turn predicts their participation in small group-discussion. While many students express a fear of negative evaluation, or dread being evaluated negatively by others when speaking out in active learning classes, I identified that how instructors structure group work can cause students to feel more or less integrated into the college science classroom. Lastly, I identified tools that instructors can use, such as name tents and humor, which can positive affect students’ social integration into the college science classroom. In sum, I highlight inequities in students’ experiences in active learning science classrooms and the mechanisms that underlie some of these inequities. I hope this work can be used to create more inclusive undergraduate active learning science courses.

Description
Monoamine neurotransmitters (e.g., serotonin, norepinephrine, and dopamine) are powerful modulators of mood and cognitive function in health and disease. We have been investigating the modulation of monoamine clearance in select brain regions via organic cation transporters (OCTs), a family of nonselective monoamine transporters. OCTs are thought to complement the actions of selective monoamine transporters in the brain by helping to clear monoamines from the extracellular space; thus, assisting to terminate the monoamine signal. Of particular interest, stress hormones (corticosterone; CORT) inhibit OCT3-mediated transport of monoamine, to putatively lead to prolonged monoamine signaling. It has been demonstrated that stress levels of CORT block OCT3 transport in the rat hypothalamus, an effect that likely underlies the rapid, stress-induced increase in local monoamines. We examined the effect of chronic variable stress (CVS) on the development of mood disorders and OCT3 expression in limbic and hypothalamic regions of the rat brain. Animals subjected to CVS (14-days with random stressor exposure two times/day) showed reduced body weight gain, indicating that CVS was perceived as stressful. However, behavioral tests of anxiety and depressive-like behaviors in rats showed no group differences. Although there were no behavioral effects of stress, molecular analysis revealed that there were stress-related changes in OCT3 protein expression. In situ hybridization data confirmed that OCT3 mRNA is expressed in the hippocampus, amygdala, and hypothalamus. Analysis of Western blot data by two-way ANOVA revealed a significant treatment effect on OCT3 protein levels, with a significant decrease in OCT3 protein in the amygdala and hippocampus in CVS rats, compared to controls. These data suggest an important role for CORT sensitive OCT3 in the reduction of monoamine clearance during stress.

Description
The transition from high school to college is associated with considerable life strain for adolescents, including higher reported levels of daily stress and negative affect (NA), and alterations in stress physiology have been linked to poor health. The purpose of this thesis was to use an ecological momentary assessment design to study associations between momentary experiences of negative affect and cortisol levels in a sample of adolescents transitioning to college. I also examined the potential moderating effects of two potential vulnerability or protective factors, alone status and perceived social support from friends. Adolescents provided salivary samples and completed paper-and-pencil diary reports of socioemotional experiences and alone status five times per day for three consecutive weekdays, as well as completed self-report questionnaires on perceived social support from friends. Within-person increases in momentary negative affect were associated with momentary cortisol reactivity. Alone status significantly moderated this association such that the association between momentary negative affect and momentary cortisol levels was only significant when individuals were with others and not when they were alone. Perceived social support from friends did not significantly moderate the within-person associations between negative affect and momentary cortisol levels. The findings add to our understanding of physiological correlates of socioemotional experiences, as well as contexts in which these associations may be exaggerated or attenuated. The findings inform our understanding of potential pathways by which physiological reactivity to socioemotional experiences may affect the health of adolescents as well as how prevention efforts could reduce potential poor health outcomes associated with heightened stress reactivity.

Description
This study examined whether changes in intervention related gains from the REACH for Personal and Academic Success program, an indicated anxiety prevention school-based protocol, vary as a function of participant youth's exposure to overprotective parenting. This study also examined if ethnicity/race (Caucasian vs. Hispanic/Latino) interacts with overprotective parenting to predict program response. A total of 98 children (M age = 9.70, SD = .07; 77.60% girls; 60.20% Hispanic/Latino) received 1 of 2 protocols (REACH or academic support) and responses were measured at post-treatment and 1-year follow-up. Findings showed that child self-regulation skills improved in the school program (REACH) for children of parents with low levels of overprotection, and child self-regulation skills improved in the control program (academic support) for children of parents with high levels of overprotection. These findings were significant in the Hispanic/Latino subsample, but not in Caucasian youth.

Description
With an increase in the discussion around mental health in general, there needs to be research geared toward how educational professionals may assist a student who struggles with anxiety symptoms or disorders. This study aimed to determine how students with anxiety and anxiety disorders are impacted by teachers' responses to their anxiety manifestations, both positive and negative, in terms of their school experience. This study also investigated students' suggestions for how teachers may effectively assist a student who struggles with anxiety. This study used self-reported data from students from an honors college via a survey and focus groups in order to investigate these topics. The results found that students value student-teacher relationships and communication, flexibility (accommodations), and empathy from the teacher. Results suggest it is important for teachers to get to know a student and understand his or her challenges before making judgments.

Description
More than 260 million people suffer from an anxiety disorder worldwide, with 40 million in the U.S. alone—18% of the American population. And that label includes everything from Social Anxiety and Posttraumatic Stress Disorder to phobias and Obsessive Compulsive Disorder. Thus, people with anxiety may not have a singular cause for their worry, but a myriad number of them that influence every aspect of their lives. And, that doesn’t include people who’ve never been formally diagnosed and don’t receive proper medication or therapy.
Unfortunately, medication has many possible side effects, and both medication and therapy are often expensive. However, there are alternatives for someone dealing with anxiety. This book proposal offers a range of solutions for anxiety management, from do it yourself techniques like guided imagery and yoga, to biofeedback devices like HeartMath, to research trials on Eye Movement Desensitization and Reprocessing, as well as Repetitive Transcranial Magnetic Stimulation. The idea was not to outline every potential solution for anxiety, but to educate people on available opportunities and empower them to take control.
Though anxiety can be managed and reduced, there is no cure. That’s because anxiety is a normal part of life, and in most cases a helpful evolutionary tool to keep people on track. But, when this anxiety becomes a burden on someone’s life, there is a plethora of alternative solutions available. Understanding anxiety and learning to manage it is not an impossible task. This thesis provides an introduction to the idea and then allows the reader to move forward on their own path as they choose.

Description
This study was conducted to look at the possible effects of art intervention on anxiety levels of homeless young adults in a local drop-in shelter. While there is a fair amount of literature on art intervention and its applicability with vulnerable populations, its specific effect on anxiety has not been extensively examined. Researchers conducted two art interventions where state-trait anxiety (STAI Inventory) was measured before and after the interventions. Researchers hypothesized that anxiety would decrease after the art sessions. Some significant results were found. Participants reported feeling less strained (p = .041), worrying less over possible misfortunes (p = .02), feeling less nervous (p = .007) and feeling more decisive (p = .001). Future research recommendations are discussed.

Description
This case study analyzed the internal controls of a real estate company using the widely accepted COSO framework. Testing of the internal environment and controls was completed using the COSO framework. The major internal control problem identified in the study was a lack of ethical standards in the control environment. In addition to this main problem, inadequate documentation, no separation of duties, and unqualified employees were also identified as violations of effective internal controls. The department of real estate ordered a "cease and desist" on August 8, 2013 due to illegal company activities. The company participated in illegal actions regarding: the trust account and company documentation and procedures. Material weaknesses were found in the company's internal controls; therefore the result of this study was an adverse opinion on internal controls.

Description
Color is an inseparable part of our world as it exists in everything we perceive (Hemphill, 1996). With this constant exposure to colors, it has been widely acknowledged that colors have a distinct effect on a person's feelings and emotions (Hemphill, 1996). In fact, researcher have found that color perception evolved as an adaptation to increase fitness for animals (Bryne & Hilbert, 2003). For humans, color is a part of many everyday associations from temperature to traffic lights to sporting events. Taking this a step further, researchers have studied the effects of color on psychological functioning and physiological responses, including anxiety. A substantial body of research developed a base of information to support the idea that color has a significant effect on humans' emotions, perceptions and behaviors. I set out to test the effects of color on test anxiety and the relationship between anxiety and test performance. It was hypothesized that paper colors red, blue, and green would have an effect on anxiety with red having the most robust effect. It was also hypothesized that there would be a correlation between test performance and anxiety. Fifty undergraduate students took a ten-question brainteaser test printed on one of the three paper colors. Results displayed a significant mead difference between the three test group colors and a significant correlation between test performance and anxiety. This study was then repeated using the colors white, blue, and red. Fifty-eight undergraduate students took the same ten-question brainteaser test. These results failed to suggest a significant mean difference between the three test groups and failed to suggest a correlation between performance and anxiety. These findings conflict with the first study, and therefore, are of interest. Possibilities for these findings are the frequency of occurrence of white and social desirability. Future directions include testing for trait anxiety prior to data collection and using physiological measures to test anxiety. Still, these results can be applied in classroom settings, office environments, and airports.

Description
Mindfulness-based stress reduction (MSBR) is a clinically standardized meditation process that has been shown to facilitate the treatment of a variety of mental and physical disorders. The known efficacy of mindfulness-based stress reduction is derived from research on participants who are defined as unhealthy in some form. The potential benefits of mindfulness-based stress reduction for individuals who are considered to be healthy is under-studied, as less attention has gone into this subject area. Information Measurement Theory is a predictive theory that simplifies reality, and through this logical simplification, allows people to predict and see into the future. The concepts that are central to Information Measurement theory are natural laws, unique conditions, and relationships of unique conditions between the past, present, and future and the event model. This project aims to answer the question of if individuals, who are considered to be healthy, experience the same beneficiary results, that mindfulness-based stress reduction models execute, through the conception and knowledge of Information Measurement Theory. This study aims to compare MBSR and IMT in order to determine the consequences of each on the individual. The purpose of this study is also to highlight the promising success that Leadership Society of Arizona has achieved through the teaching of IMT in leadership courses.
