Objective: This study looked at three key variables of fear of COVID-19, preventative behaviors, and vaccination intent among college students in the United Sates. In addition, the three key variables were compared between genders, age groups, race groups, and over time to see if there were any significant findings. <br/>Method: This longitudinal study consisted of two anonymous online surveys administered on REDCap before and after a COVID-19 vaccine became available. <br/>Results: The findings suggested positive correlations between students’ fear of COVID-19 and their preventative behaviors with the passing of time. Hispanic/Latino participants had significantly higher fear of COVID-19 scores compared to Non-Hispanic Whites and other races at Wave I and II. Participants between 25 and 30 years old had a marginally greater difference fear of COVID-19 score compared to those less than 25. Females had significantly higher mean preventative behavior score than males at Wave II. There was a significant association between race/ethnicity groups and vaccination intent. <br/>Conclusion: Knowing why different groups do not engage in recommended preventative behaviors or receive vaccinations can tell us more about what tailored interventions may need to be developed and implemented to promote health and wellbeing in this population. Further research needs to be done regarding race, gender, and age and how these different groups of college students are responding to COVID-19 and why.

“College Students' Perceived Risk of COVID-19 Infection, Protective Behaviors, and Vaccination Intent” is a thesis project based on research conducted from the end of 2020 to the beginning of 2021. This project investigated various protective behavior factors against the Coronavirus (COVID-19) based on gender, race/ethnicity, and financial difficulty of college students in the United States. The plan for this thesis project was to send out two surveys through Amazon Mturk to a group of 500 college students. The first survey further narrowed down the sample size to include only the participants who met the eligibility factors. A second larger survey was sent to this sample which included the data for this research project. This paper will explore the topics of perceived risk of becoming infected with COVID-19, preventive behaviors, vaccination intent based on gender, race/ethnicity, and financial difficulty.

The purpose of this study was to examine the effect of the comprehensive HPV educational video, “What is HPV?” on the vaccination intent of young adults. The study also aimed to collect information regarding knowledge, attitudes, and beliefs that influence vaccination and related health behaviors. The sample included 215 participants between the ages of 18-26 who had not received any HPV vaccine, were able to read and comprehend English, and had consented for participation through Amazon Mechanical Turk. After they completed the baseline survey (T0), participants were randomly assigned to two study conditions. The intervention group (n = 104) watched the “What is HPV?” video, and the control group (n = 111) read the CDC HPV Fact Sheet. Both groups then completed a post-intervention survey (T1). The analysis results show that the vaccination intent among participants in the intervention group significantly increased following the intervention (59.6% to 71.2%), while vaccination intent significantly decreased for the control group (65.8% to 55%) following the intervention. The results also show a significant difference in the changes in vaccination intent for the two intervention groups. The most change in vaccination intent following the intervention came from the group who was undecided in the initial survey. The findings of the study suggested that a brief HPV educational video that provides the most updated evidence while using non-stigmatizing language and tone has the potential to increase young adults’ vaccination intent to prevent HPV-related cancers and diseases. The findings also suggested that effective HPV education is key to combating negative attitudes and misinformation about HPV vaccines.

Food system and health characteristics were evaluated across the last Waorani hunter-gatherer group in Amazonian Ecuador and a remote neighboring Kichwa indigenous subsistence agriculture community. Hunter-gatherer food systems like the Waorani foragers may not only be nutritionally, but also pharmaceutically beneficial because of high dietary intake of varied plant phytochemical compounds. A modern diet that reduces these dietary plant defense phytochemicals below levels typical in human evolutionary history may leave humans vulnerable to diseases that were controlled through a foraging diet. Few studies consider the health impact of the recent drastic reduction of plant phytochemical content in the modern global food system, which has eliminated essential components of food because they are not considered "nutrients". The antimicrobial and anti-inflammatory nature of the food system may not only regulate infectious pathogens and inflammatory disease, but also support beneficial microbes in human hosts, reducing vulnerability to chronic diseases. Waorani foragers seem immune to certain infections with very low rates of chronic disease. Does returning to certain characteristics of a foraging food system begin to restore the human body microbe balance and inflammatory response to evolutionary norms, and if so, what implication does this have for the treatment of disease? Several years of data on dietary and health differences across the foragers and the farmers was gathered. There were major differences in health outcomes across the board. In the Waorani forager group there were no signs of infection in serious wounds such as 3rd degree burns and spear wounds. The foragers had one-degree lower body temperature than the farmers. The Waorani had an absence of signs of chronic diseases including vision and blood pressure that did not change markedly with age while Kichwa farmers suffered from both chronic diseases and physiological indicators of aging. In the Waorani forager population, there was an absence of many common regional infectious diseases, from helminthes to staphylococcus. Study design helped control for confounders (exercise, environment, genetic factors, non-phytochemical dietary intake). This study provides evidence of the major role total phytochemical dietary intake plays in human health, often not considered by policymakers and nutritional and agricultural scientists.

This dissertation is intended to tie together a body of work which utilizes a variety of methods to study applied mathematical models involving heterogeneity often omitted with classical modeling techniques. I posit three cogent classifications of heterogeneity: physiological, behavioral, and local (specifically connectivity in this work). I consider physiological heterogeneity using the method of transport equations to study heterogeneous susceptibility to diseases in open populations (those with births and deaths). I then present three separate models of behavioral heterogeneity. An SIS/SAS model of gonorrhea transmission in a population of highly active men-who-have-sex-with-men (MSM) is presented to study the impact of safe behavior (prevention and self-awareness) on the prevalence of this endemic disease. Behavior is modeled in this examples via static parameters describing consistent condom use and frequency of STD testing. In an example of behavioral heterogeneity, in the absence of underlying dynamics, I present a generalization to ``test theory without an answer key" (also known as cultural consensus modeling or CCM). CCM is commonly used to study the distribution of cultural knowledge within a population. The generalized framework presented allows for selecting the best model among various extensions of CCM: multiple subcultures, estimating the degree to which individuals guess yes, and making competence homogenous in the population. This permits model selection based on the principle of information criteria. The third behaviorally heterogeneous model studies adaptive behavioral response based on epidemiological-economic theory within an $SIR$ epidemic setting. Theorems used to analyze the stability of such models with a generalized, non-linear incidence structure are adapted and applied to the case of standard incidence and adaptive incidence. As an example of study in spatial heterogeneity I provide an explicit solution to a generalization of the continuous time approximation of the Albert-Barabasi scale-free network algorithm. The solution is found by recursively solving the differential equations via integrating factors, identifying a pattern for the coefficients and then proving this observed pattern is consistent using induction. An application to disease dynamics on such evolving structures is then studied.

Introduction. Human papillomavirus (HPV) is the most common sexually transmitted infections globally. HPV is responsible for several health concerns including genital warts, cancer of the cervix, vulva, penis, anus, and oropharynx. In China, HPV infection accounts for 69.1% of invasive cervical cancer. Currently, there is no treatment for HPV infection, but HPV vaccination has been proven to be effective against HPV-related diseases. Given the highest rate of contracting HPV and suboptimal vaccination rate in college students including international students in the U.S., it is important to investigate key factors associated with vaccine uptake among Chinese international students. Purpose. This study aimed to investigate knowledge and awareness of HPV and the vaccine, attitudes, and vaccination intention in this population. We conducted a cross-sectional online survey via REDCap. Methods. Participants who were (1) Chinese international student at Arizona State University; (2) 18 and older; (3) able to read, speak and write in Chinese or English were recruited from Arizona State University. Descriptive statistics (mean, standard deviation, frequency) and inferential statistics (Chi-square test, independent t-test) were conducted using SPSS 26.0. Results. One hundred and ten participants were included in this study (56.4% female, mean age = 24, SD = 3.7). Female students had significantly higher HPV vaccination rate than males (p = 0.000). The mean knowledge score was 8.09 (SD = 1.35); female students were more likely to receive HPV education than males (p = 0.001). The most common source of education was friends (50.7%). Three most common perceived risks were not being sexually active, being male, and not having any physical signs and symptoms. The three most common facilitators were infection prevention, access to vaccination, and ability to afford vaccination. The three most common barriers were the cost, safety, and efficacy of HPV vaccine. In conclusion, gender disparities exist among Chinese<br/>international students’ HPV vaccine uptake and HPV related education. Implication. Although Chinese international students possess moderate to high level of knowledge about HPV and HPV vaccines, they lack education from credible sources. Culturally and gender appropriate education is needed in order to address barriers of getting HPV vaccination.

Due to persistent undernutrition in India and the increased demands placed on a woman’s body during childbearing and lactation, the Indian government has implemented a program to provide supplemental nutrition packets to women in rural India. This study examines the factors influencing uptake of nutritional packets by lactating mothers in southern, rural Rajasthan. Women were recruited from 65 villages in Rajasthan, India (n=149, minimum of 2 per village) to evaluate the relationship of nutrition packet uptake and two factors--education levels and distance to the health center.
Level of education had little impact on whether or not women received the nutrition packet. Of those women with no education, 63.1% received the packet. Of those with any education, 63.9% got the packet.
In contrast, distance was strongly correlated with whether or not women received the packet. For example, of the women living within 200 meters of the health center, 93.2% received a nutrition packet. Of the women living between 250 meters and one kilometer of the health center, 68.4% received a nutrition packet. Of the women living over one kilometer from the health center, only 25% received a nutrition packet. The relationship between uptake of packets and women’s perception of distance to the health center was also explored. Out of 50 women who did not receive the packet, all of the women who said there was no health center in their village did live more than one kilometer from a health center. Of the women who lived between 250 meters and one kilometer from the health center, 40% felt it was too far. Of the women who lived more than a kilometer from the health center, 66.7% felt it was too far and 29.6% said there was no health center in their village. Again, it does not appear that ‘too far’ is just a default reason for women, but that actual distance, more so than education, is a major contributing factor in their ability to take the nutrition packet. These findings suggest that improving access to supplemental nutrition packets at the village level may increase uptake by the women.

2015 marks the deadline for the UN Millennium Development Goal 5 to reduce global maternal mortality rate (MMR) by 75% since 1990. As of 2015, MMR has only been reduced by 45%. Many international organizations claim that more medically trained midwives can meet global maternal health care needs. This study investigates two major questions. What is the role of midwives in diverse international maternal healthcare contexts? How do midwives in these different contexts define their roles and the barriers to providing the best care for women? From May to August 2015, I conducted over 70 interviews with midwives in Netherlands, Sweden, Rwanda, Bangladesh, Australia and Guatemala, interviewing between 6 and 13 midwives from each country. The majority of midwives defined their roles as supporting women's individual capacities and power through normal birth, and knowing when to refer when high-risk complications arise. Although thematic barriers vary by country, midwives in all countries believed that maternal healthcare can be improved by increased collaboration between midwives and other health care professionals, better access to culturally appropriate services, and greater public awareness of the role of midwives.

How are perceptions of morality and disgust regarding meat consumption related to each other? Which factor is more salient in determining one's willingness to eat the meat of a specific animal? How do these answers vary across religious groups? This study investigates the ways that concepts like morality and disgust are related to food preferences and hopes to shed light on the mechanisms that enforce culturally sanctioned food taboos. The study compares 4 groups of people in the U.S.: Christians (n = 39), Hindus (n = 29), Jews (n = 23), and non-religious people (n = 63). A total of 154 participants were given surveys in which they rated their feelings about eating various animals. Data from Christian and non-religious groups exhibited similar patterns such as a high likelihood of eating a given animal when starving, while results from Jews and Hindus were consistent with their religion's respective food taboos. Despite these differences, morality and disgust are strongly correlated with one another in almost all instances. Moreover, morality and disgust are almost equally important considerations when determining willingness to eat when starving.

Social structure is the product of the costs and benefits of group living. Dyadic social bonds in female chacma baboons are strong and long-standing, conferring fitness benefits upon both individuals while contributing to a greater social structure. Longitudinal grooming data collected from 2001-2007 from Moremi Game Reserve, Botswana, illuminate social network dynamics of 50 female chacma baboons. Utilizing social network analysis (SNA), we analyzed social structure above the level of the dyad to see if attribute data (age, rank, and number of close female kin) was predictive of network location. Our SNA data was longitudinal, unbalanced, and continuous. We therefore used linear mixed-effects models (LMEs) and respective AIC/BIC values to choose the most likely predictive attributes for each SNA metric. From the chosen LMEs, rank was present most often. High rank predicted a higher frequency of outward grooming, an overall lower number of grooming partners, and a less extensive social network. It appears that high-ranking females have a fewer number of social bonds than low-ranking females, but that they are stronger. Considering that enduring social bonds result in increased offspring longevity, future studies include examining the potential adaptive value of weak, transient, more numerous social bonds.
