Description
Many of the derived features of the human skeleton can be divided into two adaptive suites: traits related to bipedalism and traits related to encephalization. The cervical spine connects these adaptive suites and is itself unique in its marked lordosis. I approach human cervical evolution from three directions: the functional significance of cervical curvature, the identification of cervical lordosis in osteological material, and the representation of the cervical spine in the hominin fossil record.

Description
Menstruation has been characterized as powerful, magical, and mysterious. Historically, it was believed menstrual blood could cure leprosy, warts, birthmarks, gout, goiter, hemorrhoids, epilepsy, worms, and headaches. Menstrual blood was used as a love charm and as a means to ward off river demons or evil spirits, and could be used to honor a god (DeLaney, Lupton, & Toth, 1988, pp.8-9). Contemporary studies reveal that women around the world continue to celebrate their power to create. The World Health Organization studied attitudes of women of all socioeconomic classes in 10 countries (Egypt, India, Indonesia, Jamaica, Pakistan, Philippines, United Kingdom, United States, Yugoslavia, Mexico, Korea) and found that most women saw menstruation as a positive event (DeLaney et al., 1988, p. 14). In a similar study, Mexican-American women perceived menstruation positively, as a process that "cleans" the body (DeLaney et al., 1988, p. 14).

Description
Copper demand is surging in the U.S. and around the world as countries embrace new forms of energy to combat climate change. But copper mining – while a key strategy to address supply shortages – can serve as a vehicle for injustice by imposing socio-ecological burdens for nearby communities. Due to the growing demand for copper with resulting justice issues, more research is needed to evaluate governance for the mining sector using an environmental justice lens. The National Environmental Policy Act (NEPA) is a key environmental regulation that governs mining in the U.S. Therefore, I used a qualitative case study approach to examine how NEPA requirements shape engagement in public comment opportunities. I selected the Resolution Copper Mine as a case study because of its potential to support the energy transition but pose a significant dilemma for justice: the mine is anticipated to generate 25 percent of the U.S. copper demand each year but disturb lands that hold spiritual significance for Native American Tribes. I used the Institutional Analysis and Development (IAD) framework to analyze institutional dynamics and evaluate the NEPA process for public participation using a procedural justice lens. Drawing on interview data and document analysis, the results show that process rules such as a land exchange bill and the lengths of comment opportunities were among the key barriers for participation. Socioeconomic conditions of communities including access to social resources (i.e. access to internet and technical assistance) and institutional trust posed further barriers for participation. Hence, this study suggests that federal decision-makers should aim to better integrate procedural justice into the NEPA process.

Description
Grief reaches across all human differences and boundaries. Grief, when it does not resolve on its own, is known as complicated grief. Parents of children who die are at increased risk for experiencing complicated grief. This case study seeks commonalities and possible contributing factors for the creation of a non-profit in reaction to the death of a child. This study finds that previous achievements such as completing a marathon or graduating from a graduate program may indicate the presence of characteristics like resilience that result in the creation of a non-profit.

Description
Previous research on shame and stigma has demonstrated that undesired differences can lead to community divides and produce harmful stereotypes in communities. This is particularly true in the context of hygiene, where shame has been used to try and produce better hygiene, and instead has led to increased levels of hygiene stigma in communities. As part of the 2015 Global Ethnohydrology Study, we asked 66 respondents from rural Guatemala questions about their hygiene behaviors and beliefs. The hygiene behavior data was statistically analyzed in order to test for correlation and differences between different demographics such as gender and age. There are significant differences between both gender and age in relation to hygiene behavior and practices. Gender was the stronger determinant of positive hygiene behavior. Using the definitions of stigma from literature, the results of the hygiene behaviors measured were contextualized in order to form conclusions about hygiene stigma overall in Guatemala.

Description
The anthracycline drug Doxorubicin (DOX) is a highly effective treatment for breast cancer, but its clinical utility is limited by dose-dependent cardiovascular toxicity. The toxic effects are partly attributed to DOX-induced generation of reactive oxygen species, which may impair nitric oxide-mediated vasodilation. Exercise training activates antioxidant defense mechanisms and is thus hypothesized to counteract oxidative stress when initiated prior to DOX administration. Adult 8-week old, ovariectomized female Sprague-Dawley rats were divided into 4 groups: sedentary + vehicle (Sed+Veh); Sed+DOX; exercise + veh (Ex+Veh); and Ex+DOX. Rats in the exercise groups were preconditioned with high intensity interval training consisting of 4x4 minute bouts of exercise at 85-95% of VO2peak separated by 2 minutes of active recovery performed 5 days per week. Exercise was implemented one week prior to the first injection and continued throughout the study. Animals received either DOX (4mg/kg) or veh (saline) intraperitoneal injections bi-weekly for a cumulative dose of 12 mg/kg per animal. Five days following the final injection, animals were anesthetized with isoflurane, decapitated and aortas and perivascular adipose tissue (PVAT) were removed for western blot analyses. No significant differences in aortic protein expression were detected for inducible nitric oxide synthase (iNOS) or the upstream activator of endothelial nitric oxide synthase (eNOS), Akt, across groups (p>0.05), whereas eNOS protein expression was significantly downregulated in Sed+DOX (p=0.003). In contrast, eNOS expression was not altered in Ex+DOX treated animals. Protein expression of iNOS in PVAT was upregulated with exercise in the DOX-treated groups (p=0.039). These findings suggest that exercise preconditioning may help mitigate vascular effects of DOX by preventing downregulation of eNOS in the aorta.

Description
The purpose of this study was to evaluate the efficacy and quality of HEAL International's HIV/AIDS education prevention program for secondary school students in the Arusha region of Tanzania during the summer of 2016 using a cross-cultural teaching team. Basic HIV/AIDS knowledge and attitudes concerning risk reduction behaviors as well as towards people living with HIV/AIDS were studied among Form 1 and Form 3 students from two secondary schools in rural Tanzania. The intervention program aimed to increase knowledge and positive attitudes related to HIV/AIDS in order to motivate healthy behavior change. 211 Form 1 students and 156 Form 3 students received the intervention and completed both pre- and post-evaluation surveys. At the post-evaluation, all students showed increases in basic HIV/AIDS knowledge levels as well as positive attitudes concerning HIV/AIDS risk reduction and about people living with HIV/AIDS. Students' levels of uncertainty when answering the survey questions were also decreased. Overall, the study findings indicate that HEAL's program had a positive impact on HIV/AIDS related knowledge and attitudes of secondary school students in Arusha, Tanzania. While this study had many limitations, it also offers areas of improvement for future HEAL International volunteer programs.

Description
This project created a teaching curriculum resource guide for using the popular series, The Hunger Games, in 6th-8th grade classrooms to introduce cultural issues such as child soldiers and international development to students. Studies have shown that literature can cultivate empathy and encourage youth to act. This combined with the expanding phenomenon of participatory culture and fandom activism as outlined by Henry Jenkins demonstrate the potential for youth to learn and act when given the opportunity and resources to do so. The curriculum is composed of three units: The first is a three-week reading of the books with various activities for students to really understand the narrative and source text. The second and third units address the issues of child soldiers and international development using The Hunger Games as a framework and a keystone to build connections so that these complex issues are accessible to youth. This project is a first step in the development of a curriculum that spans the full trilogy and covers a variety of current event topics.

Description
Protein is an essential macronutrient in the human diet, but the source of this protein has both human health and environmental impacts. Health complications can result from protein deficiency, but the practices by which protein sources are raised, grown, or harvested have environmental consequences, potentially reducing biodiversity, essential habitat, and crucial stocks of natural resources. Terrestrial cultivation encroaches on natural habitats and consumes resources inefficiently, while overfishing has greatly depleted wild fishery stocks. These environmental factors, along with concerns about nutrients, contaminants and the ethics of animal protein has led to confusion about weighing the risks and benefits associated with alternative sources of protein. Providing consumers \u2014 and policy makers \u2014 with a comprehensive account of major protein sources and their impacts in an understandable form is crucial to reducing environmental degradation and improving human health. Here I provide a general framework to compare the health and environmental impacts of livestock, seafood, and plant protein, and illustrate the application of this framework with case studies for each of these categories.

Description
Because children do not have the same decision-making powers as adults in matters affecting their health, their opinions have often been underrepresented in research (Bradding & Horstman, 1999). However, there is growing interest in the way that children view health because this knowledge elicits the development of more child-centered and effective approaches to health education and intervention (Bradding & Horstman, 1999). Professionals have often utilized the write-and-draw technique in school settings to gain a better understanding of how to best implement health education programs. The "bottom-up" approach of the write-and-draw method encourages participation and has been shown to elicit thoughtful responses about how children conceptualize health (Pridmore & Bendelow, 1995). This study uses the write-and-draw method to perform a cross-cultural comparison of child perspectives of health in the United States and Guatemala, countries that represent contrasting paradigms for child health. The results of this study are consistent with previous research, especially the emergent health themes. Children from the United States and Guatemala predominantly depicted health in terms of food. Guatemalan students were more likely to refer to hygienic practices and environmental conditions, while US children mentioned vegetables, water, and exercise as being healthy. For the unhealthy category, themes of poor hygiene, chips, fat/grease, fruit, carbohydrates, and environment were mentioned more often in Guatemala, while U.S. students listed sweets and fast food more frequently. Results support claims made in other literature that children's concepts of health are shaped by life experience and social context. Potential applications of the research include exposing areas (themes) where children are less likely to understand health implications and developing educational curriculum to increase a more comprehensive understanding of health.
