Self-Harming Practices from the Perspective of Forensics: An Interdisciplinary Approach for Anthropologists.

This paper explores the ways in which forensic anthropology can utilize other forensic disciplines (psychiatry and medicine) when analyzing remains for medico-legal purposes, specifically when determining manner of death. Forensic anthropologists need not just extensive knowledge on the trauma’s morphological differences, but also the reasons behind the actions that lead to suicide or homicide. Death prevalence, the physical differences between suicide and homicide, and the psychology of those actions is extensively looked at. The author finds that there are distinct patterns in the physical remains that can be corroborated with psychological evaluations and documented prior behavior.

20% of CSU students received a failing grade in Calculus 1 between 2019 and 2021. As a required course for many STEM majors, Calculus 1 outcomes have an impact on many students. When staff discuss different teaching strategies and ways to use resources, it’s natural to compare failure rates between campuses. Different CSU campuses have different student populations, so a direct comparison of outcomes may be unfair. The proposed poster describes the process of designing an analysis that could carry out a standardized comparison of calculus outcomes across campuses. Attendees will be invited to interact with the poster by adding relevant variables and pathways with sticky notes and markers.

The California Floristic Province (CFP) is a global hot-spot of biodiversity. Creating a database of plant distributions for the CFP is pivotal to define species’s conservation status. Students associated with the Herbarium used R to create precise polygons for the range of 62 species in the CFP. We accessed publicly occurrence repositories for our target species and used a protocol to remove outliers. Using these cleaned coordinates, we created polygons of the ranges and inferred the area in square kilometers. This information was used to create a preliminary histogram for CFP plant distribution, highlighting a high percentage of plant taxa with ranges smaller than Humboldt county.

Idealism is defined as believing that desirable consequences can, with the “right” action, always be obtained. This involves decreasing the amount of negative outcomes and increasing the amount of positive outcomes. Due to the lack of a reliable and valid existing measure of idealism, our goal was to create a psychometrically sound scale. Morality and justice are two important domains that were addressed during item creation. The HIQ was compared to the Global Belief in a Just World Scale in order to establish criterion validity; the short form of the Marlowe-Crowne Social Desirability Scale was used for discriminant validity.
Assaying the Substrate Activities and Enantioselectivities of Recombinant Flavin-Dependent Monooxygenases toward Aryl Sulfides

Certain Flavin Monooxygenases (FMO) are enzymes with the potential to catalyze single-enantiomer oxidation of aryl sulfides to chiral sulfoxides. Aryl sulfoxides have a wide array of pharmaceutical and agricultural applications, but many of these enantiomers have yet to be selectively and efficiently synthesized. The enzymes examined in this study are FMOs from Mus musculus, Xenopus tropicalis, Homo sapiens, and BVMO4 and BVMO24 from Rhodococcus jostii RHA1. The genes were cloned into a vector for expression in Escherichia coli and whole-cell mediated reactions with various aryl sulfides were performed to determine their activity toward the substrates and to determine the enantioselectivity.

The Stonewall Riots in June of 1969 started the modern lesbian, gay, bisexual, transgender and queer (LGBTQ) rights movement in the United States. It took four more years for "homosexuality" to be removed from the Diagnosis and Statistical Manual (DSM). This study looks at the 20 years before the Stonewall Riots, exploring how LGBTQ people were discussed in the media. Using content analysis on more than 300 articles from the New York Times (1950-1969), we explore the evolution of language used to describe members of the LGBTQ communities, through the McCarthy era (1950-1956), the decriminalization of homosexuality in the UK in 1967, and social movements, like the riots in the summer of 1969.
Leveraging Applied Problems to Enhance the Undergraduate STEM Experience

Strong analytical skills and the ability to develop and analyze mathematical models are highly sought-after skills, especially when they are paired with the auxiliary skill set of strong scientific writing, the ability to collaborate across disciplines and effective visualizations of quantitative information. We focus on the development of these auxiliary skills by (1) offering training to teams who participate in COMAP’S Mathematical Contest in Modeling (MCM) and (2) through the PIC Math course, a problem-solving course in which students work on problems provided by an industry client.
Saudi Women Enforce Freedom of Expression
Yolena Ramirez

This project promotes freedom of expression in today’s world by demonstrating advocates in a hostile society creating a movement to show women can be just as competent as men. It is important to acknowledge women are still fighting to receive the benefits of equality in other countries. Women in all parts of the world should be able to engage and contribute within any given community to enhance the quality of society. I find it amazing that women advocates in Saudi Arabia risked their lives, ruined their reputation, and even lost their jobs in order to support the movement by demonstrating their freedom of expression.

Arcata CA Yoga Culture Ethnographic Analysis: Themes of Communalism and Individualism
Alicia Osmundson

College of Arts, Humanities & Social Sciences
A 16 week ethnographic study of Arcata Yoga Culture was performed in Fall of 2018. To present findings, the poster overviews of the application of one of numerous lens of analysis used in the final ethnography to examine research results. A dualist lens, contrasting the concepts of communalism and individualism was selected for its tangible interpretation of yoga culture specific to Arcata by looking at how people of the community interact and conceptualize yoga. This lens was used in the ethnography to provide a base for the application of additional lens that could potentially giving insight into the role and interpretation of yoga in the general West and its acculturation process.
