In light of recent high profile cases of sexual assault on university campuses, BYU's Organizational Psychology and Societal Resilience Lab explored aspects of sexual assault at faith-based universities. The unique climate of faith-based universities provides insight into the influence of gender role stereotypes and religious expectations on women's vulnerability to sexual assault within the hook-up culture. The lab conducted a qualitative meta-analysis of 25 articles about sexual assault at university campuses, sexual assault at faith-based universities, hookup culture and the roles dating apps play in encouraging hook up culture. Themes were analyzed for their consistency, intersectionality and cross-variability. Emerging themes indicated that hookup culture reinforces masculine stereotypes and hyper-masculinity. These sterotypes are associated with higher endorsement of rape myth beliefs. The anonymity and prevalence of dating apps on college campuses creates an avenue for sexual assaults to take place. The location aware aspect of dating apps also presents the opportunity for users to find those in close proximity, thus making hook-ups more convenient. These apps give users the opportunity to present themselves in socially desirable ways. There is a stark difference between the way women at faith-based universities tend to utilize dating apps than their male counterparts.

Algal blooms are a worsening issue across the United States. Algal blooms are formed by an overabundance of nutrients in the water such as Nitrogen and Phosphorus. To combat this, Utah State University is collaborating with the Central Valley Water Reclamation Center, the largest water treatment plant in Utah, with innovating ways to reduce Nitrogen and Phosphorus levels in wastewater before being discharged into the local bodies of water.

One process shows promise. The Rotating Algae Biofilm Reactor (RABR) consists of an attached biofilm growth that rotates through a growth substrate. As the biofilm grows, it assimilates the nutrients in the water, thereby transferring them from the water into the biofilm algae.

No referred literature exists on mathematically connecting RABR biofilm productivity with actual data. The purpose of this research is to formulate a model of the mass production of the RABR as a function of sunlight and rate of exposure. This process is done by combining an analytical and data-driven approach to discover the equation. Sparse Identification of Nonlinear Dynamics (SINDy) is a data-driven approach that represents a potential breakthrough in being able to identify and quantify the most important parameters influencing algae biofilm yield and productivity. This study will go through the process of creating an analytical model and then scrutinizing said model with real data and make necessary adjustments.

An analytical model using Bara and Bonneford's work on photoinhibition is provided as a baseline for this study. Some data-driven results will also be presented to address the fundamental characteristics of biofilm growth.

The biofilm harvested from the RABR has significant potential for bioproducts such as biofuel, medicine, bioplastics, and livestock feed. Across different industries, this robust model describing algae biofilm growth will provide a mathematical foundation for future algae-based biofilm technologies.

Each year, approximately 25,000 youth "age out" of foster care (Courtney, Piliavin, Grogn-Kaylor, & Nesmith, 2001). These foster youth often face barriers to higher education. In Utah, fewer than five percent of foster youth go to earn a college-degree (Hahnal; 2007; Dworsky, Napolitani, & Courtney, 2011). Foster youth who could pursue a bachelor's degree may not be encouraged to do so, as the adults surrounding them may underestimate their potential (Dworsky & Perez, 2010); Vacca, 2008). Despite the challenges youth in foster care face in the pursuit of higher education, many succeed and take advantage of education programs. A study reported that over 70% of foster youth aged 15 to 19 years old reported a desire to go to college, and an additional 19% reported a desire to attend graduate school (Tzawa-Hayden, 2004). The goal of the present study was to develop a better understanding of how to better support youth and address barriers in achieving higher education and to empower foster youth to have a voice in the system. The study interviewed 15 adults who were formerly in foster care, 10 foster parents, and 9 foster care stakeholders. In addition, interviews were audiotaped and transcribed verbatim. Transcripts were coded using qualitative techniques. Themes identified were strengths of foster youth, emotional impact of foster care, and foster care best practices. These data will be used to inform the University of Utah First Star program about areas for improvement in the pathway to higher education they create for their students. This research study will provide insight into the facilitators and barriers to higher education from multiple perspectives and will empower foster youth to advocate for themselves through the use of narratives of adults formerly in foster care, whose voices are often excluded from foster care research.

The Zika Virus (ZIKV) is a mosquito-borne disease that inhabits Aedes Aegypti mosquitoes. This disease can be passed to humans three different ways: first, through the bite of an infected mosquito; second, sexual transmission between humans who are already infected with the disease; and finally, from humans to their unborn children through vertical transmission. Several studies have shown the dynamics of ZIKV and its dependency on temperature. We developed a temperature-dependent mathematical model using systems of first order differential equations to analyze the spread of the ZIKV in an effort to control the mosquito population. Our model explicitly incorporates the temperature dependency of the vital rates of the mosquito population. Furthermore, our model will also take into account the local environmental data to show the effects of seasonality within the transmission of ZIKV. Our simulation results show the importance of temperature and its impact on the mosquito-human interaction.

Unplanned pregnancies can have negative effects, especially in poor communities. There is little research about the perceived impact of a hypothetical pregnancy. Understanding individuals' ideas about how unplanned pregnancies might affect their lives will help us understand contraceptive behavior and ideas about family formation.

We explore the perceived impact of a hypothetical pregnancy among individuals who participated in the HER Salt Lake Contraceptive Initiative (Sanders et al., 2018). We coded 800 responses to the question "Please tell us a bit more about how a pregnancy now or in the next few weeks would affect your life." A desire to avoid pregnancy for the next year was an enrollment criterium, so most participants had negative feelings about a hypothetical pregnancy. However, we found that the kind of anticipated impact varied.

The most common response was a worry about financial resources (30.6%), followed by educational goals (20.4%): "It would stop my plans of going to graduate school and hurt my financial situation greatly. It would hurt my current relationships with partners and family and would be very emotionally and physically stressful." "Pregnancy now would rock my world. I am a single mom of 2 toddlers who's going to school part time and working part time. If I were to become pregnant now or in the next few weeks I wouldn't be able to accomplish the goals that I have set for myself." About 16.9% of participants mentioned negative impact without being specific. However, 5.4% of the respondents reported positive thoughts about a hypothetical pregnancy.

Our study may help scholars and medical providers get a better understanding of the precursors of decision-making processes for contraception and family planning. It will also illustrate where individuals faced with an unplanned pregnancy may need support.

Contrary to stereotypes, past research indicates that people become more emotionally positive across adulthood. Socio-emotional Selectivity Theory posits that with shortened time horizons over the lifespan people focus more on emotional satisfaction and meaning in life (Carstensen, Isaacowitz, & Charles, 1999). This "positivity effect", is found in the fact that relative to younger adults, older adults show biases toward superior processing of positively valenced emotional stimuli (Carstensen & Mikels, 2005). Personal relationships are a key source of satisfaction and emotional well-being and from the standpoint of Socio-emotional Selectivity theory, positivity in relationships is thought to be highly prioritized by older adults. Yet, according to classic and contemporary developmental psychological theories such as Erikson's Psychosocial theory of development and Arnett's theory of emerging adulthood, younger adults should also prioritize positivity in relational functioning. There has been less theory and research that has focused on understanding how midlife adults process emotionally rich relational experiences. To better understand emotional and cognitive processes across adulthood, the current study explores age-related differences in the emotional impact of a difficult relational experience (a time one perpetrated harm against another) and age-related differences in the linguistic features of adults' narratives of these experiences. Two hundred and eighteen adults ranging in age from 20 to 69 were recruited to participate in the study through Amazon's Mechanical Turk platform. Participants were asked to recall a time when they did something that negatively impacted a personally important relationship and to then vividly recall it for 2 minutes. Then they completed a battery of questionnaires about the memory. Finally, participants wrote narratives about the memory. Data are being analyzed only for those participants who recalled memories consistent with the prompt and passed attention checks during the protocol (n = 194, female = 110, Mean Age = 43.32, SD = 13.82).

West Nile Virus (WNV) is a vector-borne illness that has circulated among birds, eventually spreading across the globe. This disease has resulted in thousands of infections and deaths. Several studies suggest that passive immunity in birds and vertical transmission in mosquitoes play a crucial role in the spread of the disease. We have developed a mathematical model to investigate the effects of passive immunity and vertical transmission within the disease dynamics. Our simulation results suggest that passive immunity increases bird resistivity to WNV and that vertical transmission among mosquitoes increases the spread of WNV. Moreover, we expect this model to be used by mosquito abatement centers to estimate the populations of immune birds and to simulate disease outbreaks in the local community.

The organization of collagen fibers within the various connective tissues of the body plays an important role in the functionality of the organs they support. While the biochemical composition of collagen lattices is largely understood, it is difficult to study how the microstructural organization of collagen affects the macroscopic tissue properties. In this project we computationally stretch stochastically generated lattices consisting of nodes joined by spring like connections representing the fibers of a collagen lattice to examine how varied nodal connectivity, fiber length and fiber orientation affect the Young's Modulus of the lattice. This information will aid biologists in the production of synthetic lattices by providing a guideline of parameters that are most important to control in the creation of lattices with specific desired properties. This in turn will provide insights into bioengineering, wound care and other medical sciences.

It has been said by critics of environmental protection that industrialized countries should not be held to global standards of conservation if less industrialized countries do not improve their conservation efforts. Though this argument is generally stated to avoid talking about the environment, it is true that all countries need to be concerned with conservation. In 2015, one of the UN Sustainable Development Goals was to improve management of the world's oceans, rivers, and coasts. This paper will highlight Mexico and show how it can improve in that area. A goal for this paper is to convince the Mexican government to place funds into a water treatment plant in Sonora and environmentally conscientious coastal developments in Veracruz. Through analysis of previous empirical evidence, we have found that the coast of Veracruz is showing bad signs of erosion due to large developments build on the coast. This has damaged the habitat there and leaves the area particularly susceptible to natural disasters. The San Pedro River, which runs through Sonora, has untreated sewage and industrial runoff flowing through it, which pollutes the habitats and farms downstream of it. These are problems that can be fixed and will help Mexico show its dedication to the Sustainable Development Goals.

Child hunger is a prevalent problem America is currently facing — or not facing. According to Merriam Webster, hunger is defined as: "a weakened condition brought about by prolonged lack of food". Naturally, a child whose basic need is going unmet is likely to experience difficulty with other aspects of life: Schooling, recreation, sleep, etc. To make matters worse is the fact that some of these children are starving needlessly, going without food when such resources are available in the very area they live in. Furthermore, Lynn Mclntyre and Jeanne Williams found child hunger to be a "robust predictor of depression and suicide ideation" amongst children as they grow into adolescence and adulthood. Children are of course powerless in this situation, as they depend upon parents for their needs.

Perhaps those equally experiencing the negative effects would be the parents — those who are solely responsible to provide for their children. It's a maternal instinct for a mother to feed ones child. When this instinct is frustrated or damned, a variety of feelings can result in the parent themselves. Feeling such as depression, failure, anger, sadness, hopelessness, and fears become prominent when such an occurrence takes place. If left unresolved, feelings within parents can escalate to: "Uncontrolled weeping, fierce crazy anger, and lashing out even at those who may be of assistance". (Lou-Marie Kruger, Marleen Lourens). Unfortunately, such feelings only tend to worsen the situation as it develops into a vicious cycle, failing to break the routine.

This being the case, we will be conducting a survey on parents to measure the beneficial effects that take place within their mental well-being as a result of being able to access the food pantry at their childrens schools.

There are many factors that contribute to a police officer's job satisfaction. This research explored the elements that determine an officer's positive or negative job perceptions. Policies, regulations, and job responsibilities in any police department can greatly influence an officer's relative level of satisfaction. Such policies, regulations, and responsibilities can be determined based on the geographic elements. Police officers from a Northern Utah police department were selected for this research. The researcher conducted interviews with 13 police officers, each from day, swing, and graveyard shifts. Interviews were held with officers who have been on the job for a long period, along with newer recruits. Such information gathered can help agencies understand what aids in improving job satisfaction, and what contributes to a negative job experience. The research can also be applied to turnover rates, and to determine what could be done to help the well-being of police officers in their line of work. However, limitations do apply to this research. Job satisfaction can be greatly affected depending on the different jobs performed within an agency and job location. However, this research only looks at one police station.

Directed attention is an important process involved in cognitive functioning. Mental fatigue from daily tasks often leaves a persons directed attention depleted. According to Attention Restoration Theory (ART), exposure to natural stimuli can restore directed attention. Although many studies have investigated the ability of natural visual stimuli to restore attention, research exploring the restoration provided by natural auditory stimuli is lacking. With an abundance of sounds found in nature, bird sounds are among the most prevalent. This study aimed to investigate the differences in restoration experienced after listening to sounds from different avian species compared to a control of listening to silence. It was expected that different species would provide varying measurements of attention restoration due to differences in the sounds each species makes. Two species of birds, the common house sparrow (P. domesticus) and the black-billed magpie (P. hudsonia) were selected based on their perceived restoration potential (PRP) score determined by Ratcliffe et al. 2016. All participants first took the sustained Attention to Response Task (SART) to place a demand on attention. Participants then listened to a recording of one of the two species or silence and immediately took the Attention Network Test (ANT) to measure the restorative effects on directed attention. Another group of participants took the ANT to serve as a baseline measure. There was no significant difference of attention interference observed between groups who listened to bird sounds or silence however, the group who only took the ANT exhibited greater interference from distractions that the group who sat in silence. These results indicate that listening to bird sounds may have a positive influence on attention restoration and spending an equal amount of time in silence may have a similar effect.

Salmonid populations are an important cultural, recreational, and economic resource throughout Alaska that are threatened by multiple sources. One often-overlooked source is damage to streambeds from recreation, especially from motorized recreation. OHV (off-highway vehicle) use can increase turbidity, nutrient loads, and erosion in these streams, which is harmful for juvenile salmonids. Stream crossings are common in the Mat-Su borough of Alaska, and enforcement for approved low-impact crossings is almost nonexistent. This study focused on developing a model, based on interviews and survey data, that explained OHV user's motive-driven stream crossings. Preliminary randomized interviews were conducted to focus survey questions, which revealed that approximately 90% of OHV users didn't know about approved crossings. Interview results showed strong motive for crossings that had low environmental impact and even stronger motive for crossings focused on safety. These interviews lead to refinements in the survey instrument, which focused on the importance of specific motives such as safety, environmental impacts, congestion, etc. and support for possible management actions, loosely based on the theory of planned behavior. Reliability analyses were conducted on the factors for the generalized linear model (GLM) to simplify the model and reduce collinearity. The model showed that safety and environmental responses were the most important predictors of crossing best practice behaviors. Signage and other indirect management methods were favored over direct management methods by survey respondents at this site. Signage focused on safety in conjunction with low-impact crossing locations was suggested to management as the best course of action. The results from this study will help inform managers in designing stream crossings and their supporting signage as OHV use continues to increase.

Several schools and workplaces have implemented a "speak-English-only" policy that tends to develop into a hostile environment. At times these policies involve students or workers being disciplined for speaking just a few words in a non-English language while at work or during personal time. In short, these policies tend to create an environment that involves publicly commenting on a person's use of their primary language in a negative way. Keeping in mind that language aids in connecting and solidifying elements of identity and social connections, I ask how bilinguals in these situations view themselves when they are speaking in English, or a non-English language (Spanish-speakers in particular). In this experiment, we analyzed if bilingual (English and Spanish) have an internalize biased depending on what language they are using in academic settings. In this experiment, we will be testing what implicit biases people have when they are presented with words in Spanish or in English through an Implicit Association Test that looks at how participants pair words, positive or negative, with themselves or with others. We expect to find that people tend to respond faster when they pair Spanish words with themselves, and slower when they pair English words with themselves. This research can help expand the knowledge of how bilinguals, or multilinguals interact with their environment, and how language impacts thoughts.

While Mongolian women face high rates of domestic abuse and low political empowerment, overall, they are more highly educated and have better health rates than men. Oppression does exist but does not neatly fit in western models of feminist thought; there is a great need to understand the historical roots of this discrepancy. The Mongol Empire is highly susceptible to great-man history, placing all credit and blame on the figure of Genghis Khan and ignoring the contributions of others. Modern historians often read the primary texts through a patriarchal lens in assuming all decisions are made by men. The primary sources support a more feminist approach in emphasizing the importance of individual women, particularly Hö’elün, Börte, and the three regent-empresses. This research looks at the primary sources, most importantly The Secret History of the Mongols and how they have been interpreted in regard to individual women and a more general depiction of women. Further, I helped excavate burials from the same period in the Darkhad region of Mongolia, and so compare the materials in female graves with the historical model in the primary sources. Material culture that is present in the archaeology helps to ground the interpretation of gender roles from the inevitable highly biased sources. Overall, this research helps to understand who a Mongolian woman is expected to be in the Mongol Empire in order to inform humanitarian interventions in the present.

The Boy Scouts of America (BSA) and the Church of Jesus Christ of Latter-day Saints (the Church) have been partners for over hundred years, with the Church chartering Cub Scout and Boy Scout troops in each of its American congregations for their boys ages 8-11 and 12-18 respectively. Within the Utah National Parks Council (UNPC) of the BSA, the high concentration of members of the Church has led to the BSA being thought of synonymously with the Church and its involvement. In May of 2018, however, the Church announced that, starting January 1, 2020, they would no longer be chartering troops through the BSA for their male youth, leading to confusion about the role of Scouting in Utah and how it would change or if it would continue. The analysis of this ethnographic data, gathered at BSA events across Utah County and Camp Maple Dell in Payson, seeks to address the ways that Scouting has been influenced by its close relationship with the Church in the UNPC, the benefits and challenges it has presented, and how those that are highly involved in Scouting (employed by the UNPC) have been dealing with the impending transition and their optimism about having a better environment for Scouting without the direct influence of the Church.

The Weber Morgan Health Department reports that there is a noticeably high rate of opioid overdoses occurring in the respective counties. Current research shows that opioid addiction and opioid related deaths are increasing across the nation. "Between 2013-2015 Utah ranked 7th in the nation for drug chemical related deaths" (CDC, 2017). The purpose of this study is to assess the influence mental health and religiosity have on opioid use and abuse in the Ogden Community. In conjunction with Ogden Civic Action Network (CAN) the Weber State University Community Research Team circulated a cross-sectional self-administered questionnaire. Findings will be utilized to better determine the needs of the Weber State University students and the members of the surrounding communities. The expected outcome of this study is findings that indicate significantly higher rates of abuse and misuse of prescription and street opioids among those who self-identify as having one or more mental disorders.

This study explores the relationship between maternal sensitivity and physiological reactivity in children across time. Maternal sensitivity is the appropriate response of a caregiver to their child's needs, while physiological reactivity describes the body's response to stressors. Physiological reactivity in this case is measured by Respiratory Sinus Arrhythmia (RSA), a measure of parasympathetic nervous system activity. Previous studies show a relationship between parental sensitivity and RSA during the same procedure; however, this relationship across time has yet to be explored. It was expected that maternal sensitivity would be associated with lower physiological reactivity to stress, or a lower RSA value. This relationship is plausible based on research about sensitive caregiving predicting attachment behavior later on.

Women were recruited during pregnancy for this study beginning in October 2018 through University of Utah associated clinics, flyers, brochures, and social media posts (Lin, et al., 2019). They then have the opportunity to continue through the study with visits at successive time points: a prenatal visit, a birth visit, a visit when the child is 7 months old, and a visit when the child is 18 months old. Data coded for maternal sensitivity was collected at 7 months during the Still Face Paradigm, a commonly used procedure for assessing infant reactivity. RSA data showing physiological reactivity was collected at 18 months during the Strange Situation Procedure, widely accepted as a measure of attachment security in infants.

Establishing the existence of the relationship between these two variables is an important first step toward helping children in less than ideal situations. This could lead to a greater knowledge of how to develop interventions, for example, with children or adolescents struggling with issues related to heightened physiological activity. Understanding these biological patterns could help them handle high levels of physiological reactivity in a productive way.
