The Effect of Transdisciplinary Pedagogy on Vocation Discernment
Morgan Kelly Miller
The Effect of Transdisciplinary Pedagogy on Vocation Discernment In its institutional learning goals, the University of Dayton includes vocation as one of its goals stating that “all undergraduates will develop and demonstrate ability to articulate reflectively the purposes of their life and proposed work through the language of vocation” (University of Dayton, 2018). How do students on UD’s campus view vocation and in what way are some areas of learning teaching vocation? The purpose of this study is to document and understand a student’s developing understanding of themselves and, in turn, vocation. To this end, I have looked at one program on campus: The Institute of Applied Creativity for Transformation (IACT). IACT teaches a creative mindset that students from many majors and backgrounds learn together to take it back to their own individual areas of study for use in interacting with those curriculums, making IACT’s curriculum and advising transdisciplinary in nature. This study provides valuable accounts and insight into the effects of IACT’s curriculum and advising model and how it effects vocation discernment for undergraduate students who participate in the program. The study is dependent on the data collected and analyzed from interviews with students working toward IACT’s certificate in Applied Creativity for Transformation. This study includes information on how students make meaning of how IACT teaches, how they think about vocation, and if IACT is affecting the meaning of vocation for these students.

The effects of caffeine on aerobic exercise performance in college student females.
Kiki Marie Hess, Kristina Kay Holmes, Anna Katherine Rose Kolesar, Leah Ann Schneider, Madeline Nicole Smith, Kelsey Morgan Tepe
Studying the effect of caffeine on exercise performance is important to determine the consumption of coffee in exercise. From previous research, it has shown consuming caffeine before exercise has positive effect on exercise, by decreasing rate of perceived exertion and increased exercise performance. The results we find through this research can help others decide whether they would drink coffee before exercising in the future. Since college students consume large amounts of coffee everyday, we want to see how it affects them while exercising. Specifically, we focused on the population of female college students in this project. The purpose of this study is to explore the relationship of caffeine on aerobic exercise performance in college aged females. The caffeine consumed by the participants will be 8oz of donut shop coffee from a keurig cup. This will be consumed one hour before exercise and we will measure aerobic exercise performance using a cycle ergometer. There will be a total of 10 female college aged participants of both coffee and non-coffee consumers. We will have the same 10 females exercise one day without coffee and one day with coffee to compare our results. We are interested in looking at the effects coffee has on heart rate, blood pressure, rate of perceived exertion, and exercise performance (survey-based). The results will be reported at the symposium once our research is concluded.

The Effects of Intermittent Fasting on Weight Loss, Mood and Energy Level
Connor Stephens Goff, Cosette Mary Riely, Erika Marie Schmitt, Diandra A Walker, Michael C Wroblewski
Between increases in sedentary lifestyles and poor eating choices, America has been fighting the obesity epidemic for decades. Increased advertising convinces consumers that they need to eat more than they do, but intermittent fasting may be the solution to the obesity issue. Intermittent fasting has become a new method for losing weight. It is not a diet meaning it does not dictate what is eaten, but rather dictates what times of the day eating is allowed. Previous research has examined how intermittent fasting can impact weight loss in participants, but none have examined intermittent fasting specifically on college-age students. The purpose of this study is to examine the effects of intermittent fasting on weight loss, mood and overall energy levels in college students. Participants will be randomly assigned to a control group, intermittent fasting with a 8 hour window and intermittent fasting with a 12 hour window. The participants will fill out daily questionnaires to track mood and energy levels throughout the experiment. Results will be presented at the Stander Symposium. The results from this study will contribute to the continuous discussion about healthy ways to lose weight as well as focusing on a population that has limited control over what they eat.

The effects of L. rhamnosus consumption on rat anxiety-like behavior
Amanda Marie Schleper
Adolescent stress in humans has been correlated with an increased likelihood of an adult individual to develop addictive behaviors, such as an alcohol use disorder. Literature has demonstrated that rats subjected to adolescent stress tend to show an increased ethanol consumption. Adolescence is a critical time of development and the link between adolescent stressors and alcohol use disorders is not fully understood yet. This study examined the relationship between adolescent stress and alcohol consumption in rats. Probiotics are bacteria with potential health benefits and have been well accepted as a dietary supplement. Literature shows that probiotics could decrease rodent anxiety-like behaviors derived from adolescent stress, such as social isolation. A previous study conducted at the University of Dayton showed that group housed rats that received probiotics exhibited increased anxiety-like behavior. This finding contradicts the positive perception associated with probiotics, showing that probiotics may have a negative impact on affective behaviors. Following two measures of anxiety-like behavior in rats, the Elevated Plus Maze and the Light/Dark Box, we did not find any significant differences between the chronically stressed and the control rats. Additionally, we did not find a difference between the groups in terms of alcohol consumption or preference. Lastly, this study did observe the same trend as our previous study in regards to the anxiety-like behavior demonstrated in the group housed probiotic group. We found that the group housed rats that consumed probiotics showed an increase in anxiety-like behavior. This trend did not include a significant difference between the groups, but was similar to what we observed previously. Moving forward, further research should be done to understand the potential benefits and risks of probiotics.

The Effects of Propionate on the Interactions of Listeria monocytogenes with the Mucosal Barrier
Katie Lynn Breitenbach
Listeria monocytogenes is a food borne pathogen that is capable of causing the disease listeriosis typically in the elderly, pregnant women, or immunocompromised people. It has a relatively high death rate in the U.S. compared to other foodborne pathogens--about 1 in 5 cases ends in death. The bacterium is an intracellular pathogen, which means it requires entrance into a host cell to carry out its pathogenic activity, grow, and spread. To do this, it must cross the mucosal barrier of the intestinal lining. Through a series of various protocols, this study primarily investigates how anaerobic conditions and short chain fatty acids such as propionate, to which we know Listeria is regularly exposed in the gut, affect the bacterium’s ability to interact with the mucosal barrier. In addition, this study also contributes an understanding of how the disease should be addressed ethically in the U.S. today.

The Effects of Rewards on Motivation Within Higher Education Residential Learning Curricula
Megan JF Will
The University of Dayton AVIATE Program strives to further students’ learning outside the classroom by educating individuals on the concepts of authorship, interculturalism, and community living within a residential curriculum. AVIATE attendees are rewarded for participation in program events via a point system which is utilized in housing assignments for the coming year. This study aims to discover what motivates students to continue their studies in a residential environment and the effect rewards and teamwork play on motivation and participation. Data compiled by the University of Dayton department of Housing and Residence Life was analyzed to determine how likely students are to attend residential educational programming, the role rewards play in learning, and students’ reliance on teamwork to achieve shared goals. Results indicate that students' motivation levels vary. While the majority of students partake in fewer than 20 AVIATE events each year, overall program participation has grown, particularly with student groups working toward the common goal of rooming together in the upcoming year. This is especially true for 5-student teams who most recently averaged attendance at 36 events per person. The exception lies with students who choose not to request roommates for the following year. These individuals may attend a single AVIATE event during the academic year. Thus, student motivation in residential learning is largely affected by a combination of the creation by teams of shared goals as well as extrinsic reward opportunities.

The Effects of Sublethal Ampicillin Exposure on Listeria monocytogenes Virulence
Marlena Rae Merling
Antibiotics can be found in sublethal levels environmentally as pollution and within the body when used as medication. Antibiotics induce stress responses and sometimes act as signalling molecules in bacteria. In order to better understand the relationship between antibiotics and bacterial infections, the effects of sublethal antibiotic exposure on the ability of Listeria monocytogenes to infect macrophages was studied. Listeria monocytogenes is an intracellular pathogen of the gastrointestinal tract that is facultatively anaerobic. Two strains of Listeria monocytogenes were tested: a lab strain and a clinical cardiotropic strain. The strains were grown in liquid media overnight aerobically or anaerobically with either no antibiotics or with a 0.05 μg/mL concentration of ampicillin, which is the main antibiotic used to treat Listeria infections. Bacteria from the overnight cultures were used to infect RAW264.7 cells (macrophages) at a multiplicity of infection of 10. The number of intracellular colony forming units (CFUs) were measured at 2 and 24 hours post-infection by plating the cellular lysate. Using the number of intracellular CFUs, the percent input was calculated to measure amount of Listeria present inside the macrophages at each timepoint. The results for both strains showed no significant difference in the ability to infect and replicate inside macrophages between Listeria grown with or without ampicillin. Interestingly, the aerobically grown cardiotropic strain had a significantly lower percent input than the lab strain at 2 hours post infection, but there was no significant difference in percent input between the strains at 24 hours post infection. This suggests that although the cardiotropic strain cannot infect macrophages as well as the lab strain, it can either grow better or resist macrophage killing better than the lab strain. Future directions include testing higher levels of antibiotics and exploring the differences in virulence between strains of Listeria monocytogenes.

The effects of temperature on delayed onset muscle soreness (DOMS)
Cindy Catherine Carballada, Grace Coler, Gianna M Di Silvestro, Kate Jane Klein, Madeline Grace Salach
The issue that this study will address is what is the best way to relieve muscle soreness after exercise. More specifically, this study will help determine how different temperature (i.e. hot & cold) will help relieve delayed onset muscle soreness more efficiently. The settings of this project will be to place the participants into a highly heated pool or an ice bath. To collect data, interviews with 4 individuals, 2 males and 2 females, will be conducted. The interviews will be conducted after the individuals exercise to obtain delayed onset muscle soreness (DOMS) information and then either use hot or cold temperatures to relieve it. The exercise will consist of various resistance training focused on the lower body. Participants will exercise their hamstrings, quadriceps, adductors, and so on, which will then lead to the immediate application of heat or cold therapy. The study will also have a control group in order to compare the results to a baseline of the specific exercises without temperature application post-workout. We plan for our data to show results of DOMS in individuals and determine which temperature provides the best relief. The detailed findings will be reported at the symposium.

The factors that lead Non-Native English Speaking Students to Plagiarize in Higher Education: Teachers and Students Perspective
Salha Ahmed M Alahmari
The factors that lead Non-Native English Speaking Students to Plagiarize in Higher Education: Teachers and Students Perspective Over the past years, the number of graduated from institutions of higher learning has increased gradually. This can be attributed to the increasing demand for well-educated individuals in the job market. However, the job market has increased its demand for the quality of graduates. This can be attributed to the fact that most students who graduate from these institutions of higher learning barely produce their work. Most of these students practice plagiarism. Plagiarism still is a relevant problem to this day. This happens to be the case especially among non-native English speakers, who find it hard to cope with the strict rules on plagiarism. Most of these students lack the confidence in themselves to produce good quality writing. They therefore “borrow” from other more proficient writers (“(PDF) Plagiarism awareness, perception, and attitudes among students and teachers in Swedish higher education - a case study,” n.d.), which is wrong. With the increasing cases of plagiarism, one tends to wonder whether the institutions of higher learning are doing their part in ensuring that plagiarism is curbed at its core. In spite of putting in measures such as expulsion for students found guilty of the act, plagiarism is still practiced in these institutions. Taking a closer look, one could ask whether the teachers are doing enough to ensure their students are doing enough to ensure that this crime is not committed in their classes. This study will look at the plagiarism and the role that both the teachers and students play in enhancing it.

The Grand Ethiopian Renaissance Dam: A Window of Opportunity or a Door for Exclusion?
Alyssa Marie Miller
The Nile River is one of the longest rivers in the world that flows through 11 countries. The Blue Nile River is a tributary to the Nile River, which starts from the highland of Ethiopia and contributes around 85% of water flow to the Nile that flows upstream into the Mediterranean Sea. With the aims to solve the water problem and enhance their development, the Ethiopian government started building the Grand Ethiopian Renaissance Dam (GERD) on the Blue Nile River in 2011. Since this river is a tributary to the Nile River, many spectators questioned how Ethiopia has the jurisdiction to build a dam over a river that is transnational. There have been various legislation agreements established, but very few have had significant impact to lessen the tension. Most notably, to solidify each country’s adequate supply, the UN adopted the Convention on the Law of the Non-navigational Uses of International Watercourses in 1997, which attempted to set standards around the usage and conservation of watercourses. Though this convention can help resolve the geopolitical tension over the GERD’s construction on the Nile River, it does not solve the question of Ethiopia’s right to build a dam that could impact other countries water supply. Therefore, in 1999, the Cooperative Framework Agreement (CFA) grants each country that the Nile River flows through, the right to adequately use the Nile's water supply. However, Egypt is one of the countries that originally did not sign the CFA. The Nile is Egypt’s primary source for freshwater. Egypt’s main concern is since their population continues to grow, their freshwater supply will deplete. Though it may be perceived to negatively impact Egypt, the GERD seems to benefit countries, especially Ethiopia and Sudan, in terms of economic development. Hence, I am to explore how the GERD will benefit and restrict Ethiopia, Sudan, and Egypt’s commercial growth. I will also explore journal articles and media sources to further analyze the complex geopolitical situation in northeastern Africa.

The Impact of an Interdisciplinary Program on Undeclared Students’ Academic Major Choice and Vocation Discernment
Marissa L McCray
While selection of an academic major is pivotal for undeclared students, many lack direction and struggle to understand the meaning of prescribed, seemingly unrelated general education courses traditionally required in the initial college curriculum. Moreover, many undeclared students grapple with a sense of calling or purpose among academic choices, future careers, and broader facets of emerging adulthood. An interdisciplinary curriculum counters the disconnect between compartmentalized disciplines and helps students recognize connections between disciplines and wider contexts. The purpose of this qualitative case study is to explore how the University of Dayton Core Program shapes undeclared students’ academic major selection and vocational outlook. This study examines Core students who began the program as Discover Arts (undeclared) and evaluates how Core shaped their academic major selection and vocation discernment. Qualitative data was collected from one-on-one interviews with junior Core students who recently completed the 2 ½ year interdisciplinary program. Findings revealed numerous themes and patterns surrounding the academic major selection process and the impact made by the Core Program during discernment. This study assesses future implications for continued best practices and seeks to address a gap in the literature about the influence of interdisciplinary curricula on undeclared students’ choices about academic major and vocational outlook.

The Impact of Home and College Tension on Grit in First-Generation College Students
Kaley Lynn Meyer
In the context of higher education, students who have parents with postsecondary degrees have an advantage over those who are first in their families to attend college. One of the most commonly discussed challenges for first-generation students is navigating the tension they experience from living lives in two different worlds: life at home and life at college. Interestingly, however, some literature illuminates how the unique challenges first-generation students face often make them more determined, persistent, resilient and prideful in their collegiate endeavors (O'Neal et al., 2016; Strayhorn, 2013). Scholars have discussed these particular characteristics as signs of grit and studies have shown grit to be positively associated with academic achievement (Duckworth, Peterson, Matthews, & Kelly, 2007; Kannangara, et al., 2018; O’Neal et al., 2016; Strayhorn, 2013). If first-generation students tend to display grit in their educational pursuits, then why are they more likely to drop out of college than their non-first-generation peers (Chen & Carroll, 2005)? This quantitative study is an attempt to dissect this phenomenon to better understand why some first-generation students persist and others succumb to the various challenges they face in postsecondary education. Through utilization of the Grit Scale and the Home and College Tension Scale, this study determines the extent in which perceived tensions between connections to home and college experiences influence grit in first-generation students. With this information, educators and administrators can expand their understanding of the complexities of the first-generation experience and further enhance various supports for this particular population. The findings from this study provide specific implications for future practice and research on first-generation students, grit development and the overlap of the two domains.

The Importance of Novel Molecule Properties in the Formation and Advancement of Alternative Jet Fuel Blends
Lily Carolyn Behnke
The development and use of new alternative jet fuel blends and high energy molecules has the potential to greatly improve conventional jet fuels, both environmentally and economically. These fuels and blends are dependent upon their performance and operability standards as well as the chemical and physical properties of the novel molecules within them. High energy molecules have the potential to increase the total specific energy (MJ/kg) and energy density (MJ/L) values of a fuel with the intention of increasing overall aircraft efficiency. The properties of these high energy molecules are essential in determining their viability for blending and optimization, and therefore must be thoroughly analyzed to consider the eligibility of these molecules. The blending of novel high energy molecules with conventional jet fuels are bounded by ASTM specifications to produce alternative jet fuel blends that could be implemented in commercial airlines. With a global optimum in mind, the progression of alternative jet blends has the potential to improve aviation by lowering gas emissions and improving overall aircraft performance.

The Influence of Study Abroad on School Psychologist Cultural Competence
Alexa Marie Irwin
Cultural competence and the ability to effectively serve children and families from diverse backgrounds has increased in importance in social services fields. Professional associations such as the National Association for School Psychologists place particular value on cultural competence for school psychologists due to the lack of diversity in the field and the changing demographics of U.S. schools. Research demonstrates that study abroad experiences during undergraduate or graduate school are an effective way of developing cultural competence in teachers, counselors, and school psychology graduate students. However, there is limited research on the long-term influence of study abroad experiences on the cultural competence of mid-career school psychologists. Ten mid-career school psychologists were interviewed for this qualitative study. The purpose of this study was to examine how a study abroad course, taken during an undergraduate program or graduate program, had any lasting professional or personal impact on mid-career school psychologists. This study further explored other factors that contribute to mid-career school psychologists’ perceived cultural competence. Five themes related to cultural competence emerged following analysis, including: (1) awareness, (2) exposure, (3) cultural immersion, (4) willingness to learn, and (5) professional development. Six themes related to long-term influence of study abroad on perceived cultural competence emerged from the analysis, including: (1) increased openness, (2) different perspectives, (3) learning about other cultures, (4) recognition of our similarities, (5) relating to students from different backgrounds, and (6) contributions to practice. The findings are presented along with implications for future research.

The Journey of Career Services at Minzu University of China
Shu Yang
Compared to the holistic history of China, career services in China are relatively new. The purpose of this qualitative case study is to explore the development of career services at Minzu University of China. Through interviews with current students, alumni, and faculty members at Minzu University of China, this study helps us to form the blueprint of career services at Chinese institutions. From a different lens, it also helps us to see the limitation of the career services at Chinese institutions. The findings enhance our understanding of how culture impact its people and how the development of the society impact its people’s career planning. The findings also support potential improvement plans for the career services at both Minzu University of China and other institutions in China.

The Melody of Spatial Memory
Victoria Lynne Karpuszka
Music has been studied extensively in psychology, including research on musically-induced emotion. However, the project reported here looked at new effects of musically-induced emotions on spatial memory. Palmiero and colleagues (2016) established that music and emotions are associated. Music of a major mode, or an Ionian mode, is usually associated with positive emotions. Music of minor modes, such the Locrian or Aoelian modes, are associated with negative emotions. These associations with the specific modes are seen by the lowering of the third and sixth scale tones. Participants for the present study completed a spatial memory task (called the “Tower of Hanoi”) while listening to music of different valences (found in previous research to create feelings of positive and negative emotions). Participants completed the task both with and without music playing. Following completion of the tasks, participants reported on emotional state using the Positive and Negative Affect Scale (PANAS; Watson, Clark, & Tellegen, 1988). I hypothesized that those who listened to the positive-valanced music while completing the spatial task would perform better (i.e., faster) than those who listened to the negative-valanced music. Preliminary results indicate this to be true. In addition, participants exposed to negative-valenced music were less likely than those participants exposed to positive-valenced music to complete the spatial memory task in the required amount of time. Participants generally reported a mood score on the PANAS that decreased, regardless of the induced mood (positive- or negative-valenced) after working on the spatial memory task. This result appears to be related to the inability to complete the task or the length of time needed to complete the task.

The potential role of mir-277 in Alzheimer’s disease
Prajakta D Deshpande, Brent O Mcginty
As the most common progressive neurodegenerative disorder, Alzheimer’s disease (AD) has been predominantly found in people 65 years of age or older. AD is associated with a gradual decline in cognitive impairment and memory as well as effects on behavior and decision making. AD is also responsible for the most dementia cases in elderly people. As per the Alzheimer’s Association facts, over 5 million Americans were affected by AD in 2018 whereas the number is predicted to rise to approximately 14 million in 2050. One of the causes of AD is mis-cleavage of the transmembrane protein called amyloid precursor protein (APP) by the enzymes β-secretase and γ-secretase, resulting in accumulation of amyloid beta-42 polypeptide (Aβ42). These amyloid beta peptides aggregate into hydrophobic plaques in the extracellular region in the brain, altering the cellular pathways and resulting in neuronal death. In this study, we have used Drosophila as a model system and misexpressed the human Aβ42 in the photoreceptors of the Drosophila eye. The misexpression of the Aβ42 in the Drosophila eye triggers the neuronal cell death resulting in a glassy reduced eye phenotype. This study focusses on how microRNA mir-277 regulates the Aβ42 mediated neurodegeneration. MicroRNA regulate the gene expression post-transcriptionally and repress the protein formation by sequence-specific degradation of target mRNA. Earlier studies have shown the association of microRNA in AD and the role of mir-277 in AD is not clear. This study adds to our understanding of the role mir-277 may play in Aβ42 mediated neurodegeneration and its potential role as a biomarker for AD.

The Presentation of Stigmatized Health Issues in Network Television Content
Franchesca Robin Hackworth
The present investigation attempts to provide a more comprehensive investigation of stigma in media by exploring representations of two important stigmatized health contexts (mental illness and HIV/AIDs) in a representative sample of television programming. The study has three objectives: 1) identify the program types more likely to contain information about these stigmatizing health conditions, 2) explore differences in stigmatizing information present in each program type, and 3) explore similarities and differences between contexts. Findings from the investigation have the potential to provide insights for media literacy initiatives (i.e., identifying particularly problematic exposure points) and stigma reduction messaging (i.e., identifying specific cues that need to be corrected or dispelled through campaign or treatment efficacy messages). A television sample of 672 total hours of content was coded for mentions of HIV/AIDs and mental illness. Discussions of mental illness were about 10x more prominent than those of HIV/AIDs and across a diverse range of programming types, while HIV/AIDs mentions were limited to news, commercials, and talk shows. Mental illness content was often associated with the advertisement of a drug. Mental health has the potential to be more stigmatized because of its frequent presence. Local news contained the most content for both health issues (39% HIV/AIDs and 35% mental illness), followed by commercials (29%) and drama (19%) programming for mental illness and talk shows (35%) and commercials (17%) for HIV/AIDs. It may be possible that different production techniques and demands for different programs facilitate portrayals of health issues in different ways. An investigation such as this one allows for comparison between program type within the same time frame, an analysis that is missing from the present landscape of scholarship. We hope to provide directions for stigma reduction messages and areas of attention for media scholars.

The Prevalence of Aversive Racism in the Reality TV Show Survivor
Jessica Nicole Eischen, Michael Terrence Stark
Aversive racism is a form of prejudice and discrimination in which individuals who profess egalitarian ideology and hold non-prejudiced self-views discriminate towards racial minorities in subtle, rationalizable ways (Gaertner & Dovidio, 2000). Unlike overt, intentional racism, aversive racism is characterized by feelings of uneasiness about racial minorities rather than hate and hostility; however, it still results in discrimination towards racial minorities. Research examining white people’s attitudes and behavior towards black people finds that one context in which aversive racism occurs is when discrimination towards black people can be blamed on non-racial factors. That is, people fail to identify race playing a role in why they behaved more positively towards other white people than they did black people. The present study seeks to examine the prevalence of aversive racism in the reality-television series, Survivor, where contestants vote someone out of the game each week in order to win a one-million dollar prize. With few exceptions, the majority of contestants each season are white, and attribute their decision of who to vote out of the game to various non-racial factors. We will examine the association between contestant race and the rate at which they are voted off the show by the other contestants. Aversive racism predicts that, although there are usually far fewer non-white contestants each season, non-white contestants would be voted-off at a disproportionately higher rate than the white contestants.

The Prickly Problem of Pears: Potential effects of native orthopteran herbivory on an invasive woody plant
Kaitlin Marie Gawkins, Tara Brianna Masthay
Across the United States, land managers are struggling to cope with a relatively new invasive species, Callery pear (Pyrus calleryana). At the present, Callery pear is one of the most important invasive species threatening prairies and early successional habitats in Ohio and the Midwest, and yet, there is no viable means of control that is widely used for this species. This is due to the fact that this species is resistant to herbicides and resilient against prescribed cutting/burning. One potential management strategy of invasive species is biocontrol, or the intentional introduction of natural enemies to control the growth and propagation of a target organism. Previous experiments with Callery Pear have been limited herbivory by large animals, thus, an important knowledge gap exists in the interactions between native insect herbivores and the woody plant. In order to explore this knowledge gap, we conducted a month-long field enclosure experiment where we manipulated the species richness of native orthopterans in enclosures with either a Callery Pear sapling or a similar native tree sapling, American Basswood, and destructively measured the biomass of the tree and vegetation in each enclosure. We then calculated the percent change in biomass between the treatments and controls to determine if varying the orthopteran species richness had any effect on plant growth. We found that in treatments with a high species richness of orthopterans, there was a larger positive percent change in Callery Pear biomass. This was opposite to what we expected due to the fact that, traditionally, a higher diversity of herbivores would lead to an increase in herbivory and thus a decrease in biomass. This should be studied further in order to understand how intentional reinstatement of insect diversity to early successional areas by environmentalists may actually be helping invasive species to grow more rapidly.

The Relationship Between Growth Mindset and Students' Psychological Well-Being
Kelly Marie Berlin
Research suggests that adopting a growth mindset can have positive implications for students’ academic outcomes, adjustment, academic emotions, and motivation. Having a growth mindset is also positively associated with resilience, which is positively associated with psychological well-being. The present study examined the relationship between high school students’ self-reported levels of growth mindset and psychological well-being. Results of a survey given to (n = 85) high school students demonstrated no significant relationship between students’ overall levels of growth mindset and psychological well-being. Further, results indicated that no significant relationship existed between growth mindset and any individual domain of psychological well-being (i.e., autonomy, environmental mastery, personal growth, positive relations with others, purpose in life, and self-acceptance).

The Role of Short Chain Fatty Acids in the Activation of Macrophage Production of Nitrogen Radicals by Listeria monocytogenes Infections
Megan Rose Bias
Macrophages are important immune cells that can help protect our health by engulfing and destroying pathogens. For macrophages to work, they must be activated when there is a threat. My study focused on testing the effect of propionate, acetate, and butyrate on the ability of macrophages to produce nitrogen radicals. Propionate, acetate, and butyrate are short chain fatty acids that are present in the human body. They help with regulatory functions that are important for our health. We do not yet know how these short chain fatty acids can affect the macrophages’ ability to destroy possible threats. Macrophages have many ways to destroy pathogens, such as the production of nitrogen radicals. The production of nitrogen radicals can be measured through a nitrite assay. The macrophages were infected with Listeria monocytogenes that had been treated with one of the short chain fatty acids and then we measured the amount of nitrite production in the cell media. High levels of nitrite indicate high nitrogen radical production. Results from my study helped me understand how short chain fatty acids impact susceptibility to infections in the human body.
The Brother Joseph W. Stander Symposium recognizes and celebrates academic excellence in undergraduate and graduate education. This annual event provides an opportunity for students from all disciplines to showcase their intellectual and artistic accomplishments. The Stander Symposium represents the Marianist tradition of education through community and is the principal campus-wide event in which faculty and students actualize our mission to be a "community of learners." This collection contains a sampling of the posters presented during the symposium in 2019.
