Description
In response to a national call within STEM to increase diversity within the sciences, there has been a growth in science education research aimed at increasing participation of underrepresented groups in science, such as women and ethnic/racial minorities. However, an underexplored underrepresented group in science are religious students. Though 82% of the United States population is religiously affiliated, only 52% of scientists are religious (Pew, 2009). Even further, only 32% of biologists are religious, with 25% identifying as Christian (Pew, 2009; Ecklund, 2007). One reason as to why Christian individuals are underrepresented in biology is because faculty may express biases that affect students' ability to persist in the field of biology. In this study, we explored how revealing a Christian student's religious identity on science graduate application would impact faculty's perception of the student during the biology graduate application process. We found that faculty were significantly more likely to perceive the student who revealed their religious identity to be less competent, hirable, likeable, and faculty would be less likely to mentor the student. Our study informs upon possible reasons as to why there is an underrepresentation of Christians in science. This further suggests that bias against Christians must be addressed in order to avoid real-world, negative treatment of Christians in science.

Description
The goal of my study is to test the overarching hypothesis that art therapy is effective because it targets emotional dysregulation that often accompanies significant health stressors. By reducing the salience of illness-related stressors, art therapy may improve overall mood and recovery, particularly in patients with cancer. After consulting the primary literature and review papers to develop psychological and neural mechanisms at work in art therapy, I created a hypothetical experimental procedure to test these hypotheses to explain why art therapy is helpful to patients with chronic illness. Studies found that art therapy stimulates activity of multiple brain regions involved in memory retrieval and the arousal of emotions. I hypothesize that patients with chronic illness have a reduced capacity for emotion regulation, or difficulty recognizing, expressing or altering illness-related emotions (Gross & Barrett, 2011). Further I hypothesize that art therapy improves mood and therapeutic outcomes by acting on the emotion-processing regions of the limbic system, and thereby facilitating the healthy expression of emotion, emotional processing, and reappraisal. More mechanistically, I propose art therapy reduces the perception or salience of stressors by reducing amygdala activity leading to decreased activation of the hypothalamic-pituitary-adrenal (HPA) axis. The art therapy literature and my hypothesis about its mechanisms of action became the basis of my proposed study. To assess the effectiveness of art therapy in alleviating symptoms of chronic disease, I am specifically targeting patients with cancer who exhibit a lack of emotional regulation. Saliva is collected 3 times a week on the day of intervention: morning after waking, afternoon, and evening. Stress levels are tested using one-hour art therapy sessions over the course of 3 months. The Perceived Stress Scale (PSS) assesses an individual's perceived stress and feelings in past and present situations, for the control and intervention group. To measure improvement in overall mood, 10 one-hour art sessions are performed on patients over 10 weeks. A one-hour discussion analyzing the participants' artwork follows each art session. The Spielberger State-Trait Anxiety Inventory (STAI) assesses overall mood for the intervention and control groups. I created rationale and predictions based on the intended results of each experiment.

Description
In 2015, the World Health Organization cited antibiotic resistance as one of the greatest current challenges to global public health. A major driver of the evolution of antibiotic resistance is the overuse and misuse of these drugs. While antibiotic stewardship, education campaigns, and health policy attempt to limit drug use globally, public understanding of antibiotic resistance and its consequences are lacking. The goal of this study is to analyze the social and cultural influences of antibiotic knowledge and usage behavior. Over a three-month period, I interviewed 211 laypersons in Guatemala, Spain, the Netherlands, India, South Africa, and New Zealand to understand their ideas, perceptions, and behaviors regarding antibiotics and compared results across countries. While an overall consensus across countries does exist, I found significant differences between low and high income countries as well as between low and high antibiotic consumption countries. Additionally, I found that having increased public health knowledge is related to lower antibiotic "risky" behavior. These results help contextualize national data on antibiotic consumption and resistance by illustrating relationships between access, beliefs, and consumption patterns within populations. The results also inform the development of community and culture specific educational campaigns regarding antibiotic resistance.

Description
This paper explores the idea of xenophilia and the circumstances under which it may occur. Xenophilia is the preference for an outgroup member over an ingroup member. This preference does not have to be amicable, and in fact can be exploitative under certain circumstances. Previous research indicates that xenophobia is much more common, but a few researchers have found support for the existence of xenophilia. To experimentally test the circumstances under which xenophilia might occur, I conducted a survey-based experiment on Amazon’s Mechanical Turk. This consisted of directed visualizations that manipulated participant goal (self-protection vs. mate acquisition) and the resources offered by both a fictitious outgroup and the hometown ingroup, followed by measures of ingroup/outgroup preference. I hypothesized that when the resource offered by the group addressed the participants’ goal, they would prefer the group with the “matched” resource—even if it was the outgroup providing that resource. My hypothesis was not supported, as the univariate analysis of variance for preference for the outgroup was not significant, F (2, 423) = .723, p = .486. This may have occurred because the goal manipulations were not strong enough to counteract the strong natural preference for ingroup members.

Description
Cardiovascular disease is the leading cause of death in the United States, and classic risk factors only predict half of the variance of cases. In this study, parental overprotection and temperamental negative affectivity both significantly correlated with blood pressure and heart rate, which suggests the importance of examining early life factors when determining one's risk for CVD.

Description
Hand-coding systems of measuring facial expressions were developed to study and analyze human emotions, but they are time-intensive and thus seldom used. As technology has advanced, new computer software programs, such as Affectiva, were developed to code facial expressions automatically using artificial intelligence and machine learning. Since this technology is still new, Affectiva and its validity remain understudied, and no psychological research has been conducted to compare Affectiva computer coding and hand coding of children’s emotions. The purpose of this study was to compare hand and computer coding of children’s expressions of emotion during a videotaped parent-child interaction. The study answered the following questions: 1) Do hand and computer coding agree?; and 2) Are hand and computer coding in higher agreement for some emotions than others? The sample included 25 pairs of twins from the Arizona Twin Project. Facial expressions were coded from videotape by a trained and reliable human coder and using the software Affectiva. The results showed that hand and computer coded emotion were in agreement for positive, but not negative emotions. Changing the context of the interaction to elicit more negative emotion, and using the same indicators of each emotion in computer and hand coding are suggested to improve the comparison of computer and hand coding.

Description
Human trafficking is a widespread global health issue impacting communities both locally and globally. Despite its prevalence in our world, there is a lack of education amongst healthcare providers. Research suggests that more than 80 percent of human trafficking victims encountered one or more healthcare professionals while being trafficked. Of these providers encountered, 60 percent were emergency department personnel (Lederer & Wetzel, 2014). Although emergency department personnel have a high rate in interaction with victims, less than 5 percent have received formal training regarding human trafficking (Lederer & Wetzel, 2014). It is my goal to better educate current and future healthcare professionals on human trafficking. Through education, more victims can be recognized and be offered the resources they deserve. In order to do this, I want to understand current perceptions, knowledge, and beliefs that healthcare personnel have, and how education affects these perceptions. To gain this information, I will distribute the same survey to healthcare professionals before and after receiving a formal training on human trafficking. Through this survey, I hope to better understand how education affects people’s perceptions, knowledge, and beliefs on human trafficking.

ABSTRACT
Overview: There has been very little research done into the topic of mental illness in general, and Alzheimer’s Disease specifically, in Guatemala. The existing research accounts for prevalence of mental illness in Guatemala with an estimated prevalence of a mental illness of 27.8% (Guatemalan Government, 2009). Alzheimer’s Disease is less well researched.
Research Question: This research addresses this gap in knowledge by focusing on the stigma felt toward people who had Alzheimer’s Disease and Related Dementia (ADRD) by the people of Guatemala.
Participants: One-hundred twenty-four individuals over the age of 18 were recruited for participation. Participants were recruited through opportunity samples in artisan markets in Antigua.
Procedures: Participants completed a survey including demographic questions, the Dementia Attitudes Scale (O’Connor & McFadden 2010), as well as open-ended questions regarding the causes, symptoms, and treatments for Alzheimer’s. The study was conducted from July 2, 2018 to August 2, 2018.
Results: The average DAS score of 100.31± 14.01 found in this study is similar to results from other studies conducted in the United States (O'Connor & McFadden, 2010). Factor analysis did not verify the existence of sub-scales in the survey, as found in previous studies. The free-response questions indicated that many people may believe that ADRD is an inherited disease or one that is caused by factors outside of their control.
Conclusions: The high DAS score of 100.31± 14.01 matches other studies that used the DAS. Scores of 103.51± 13.43 (Scerri & Scerri, 2013) were reported in other studies and interpreted as positive as it relates to stigma. This points to a low stigma level in Guatemala. The failure to verify the sub-scales leads to the conclusion that although scales are validated in western nations, they may not be culturally portable. The DAS scale may not be measuring the same thing in this sample’s population versus previous studies sample populations.
