Description
Previous studies have demonstrated that cranial base anatomy is influenced primarily by three different characteristics: brain shape, positional behavior, and facial growth (Lieberman et al. 2000). Although the timing of cranial base growth is not fully understood, features of the cranial base are frequently used to interpret the hominin fossil record (Guy et al. 2005; White et al. 1994; Brunet et al. 2002). While specific aspects of cranial base morphology may be species-specific, there is sparse information on the developmental mechanisms driving these adult morphologies. The aim of this study is to 1) examine changes in the human cranial base form throughout ontogeny and 2) determine their relationship to the development of positional behavior and brain growth. This research asks: to what extent does human cranial base morphology vary before and after adult positional behavior is acquired? The null hypothesis is that there is no relationship between features of the cranial base and the development of positional behavior. Data are collected using 3D landmarks on n=35 human crania and analyzed with both Morphologika (O'Higgins and Jones 1999) and MorphoJ (Klingenberg 2011) to identify age related changes in shape. Results of this study demonstrate that most of the changes in cranial base form occur between dental eruption stages N and NJ1 between 0 and 2 years of age. These changes consist of a relative shortening of the anterior-posterior cranial base length, a more posterior positioning of the foramen magnum, and a more anterior position of the occipital condyles and separate the N and NJ1 dental development groups from other groups. This change coincides with the transition to upright posture in human children (Abitbol 1993), a significant period of brain growth (Neubauer 2009) and has implications for reconstructing positional behavior in fossil hominins. Despite new insights into the development of cranial base morphology, the utility of the cranial base in assigning hominin taxonomy remains inconclusive.

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.

Throughout the course of the Honors Thesis/Creative Project, the intent was to gain knowledge regarding national, state and community initiatives regarding Indigenous Language Revitalization and Maintenance (ILRA). For over a year, I had the opportunity to visit a total of five indigenous communities, including Pine Ridge, SD, Gila River Indian Community, AZ, White Mountain Apache, AZ, Cochiti Pueblo, NM and Santo Domingo Pueblo, NM. The goal was to learn about the status of their language, current ILRA initiatives as well as challenges and successes that face American Indian nations. During each visit, key elements to successful language revitalization initiatives were identified that could benefit those continuing their effort to reverse language loss as well as those looking to enter in the field of language revitalization.

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.

Description
This manual provides a "how-to" framework for the development of a student-run clinic. The manual should be used as a resource, referring to the table of contents and summaries of topics for specific areas of interest. The manual details the phases for the development of a student-run clinic focusing on underserved populations. The Student Health Outreach for Wellness (S.H.O.W.) Community Initiative in Phoenix, Arizona serves as the example. S.H.O.W. represents just one type of clinic structuring. As such, it is important to realize when developing a clinic that there are numerous clinic approaches based on community needs, volunteer support, and funding.

Description
With an increasing global interest in Chinese economics and society, more and more native English speakers have started to learn Chinese as a second language (L2). While English and Chinese share a similar word order at the syntactic level, they differ significantly in ways to keep track of reference at the discourse level. There are generally three ways to keep track of reference: repeating the full noun phrase (NP), replacing the full NP with a lexical pronoun, or omitting the NP using zero anaphora. Chinese, a topic-prominent language, allows a wide use of zero anaphora to maintain reference; whereas English, a subject-prominent language, allows only a limited use of zero anaphora. Due to this difference, Chinese as a second language learners whose native language is English (CSL learners), must learn to implement the use of zero anaphora more frequently in their Chinese discourse. The purpose of this study is to investigate how CSL learners keep track of reference using zero anaphora. It is hypothesized that CSL learners at intermediate proficiency level would display a transfer effect from English to Chinese in their Chinese discourse. Specifically, they would produce fewer zero anaphora than native Chinese speakers, and they would also tend to consider discourse with many uses of zero anaphora for reference tracking as less appropriate. To test the hypothesis, a story-retelling task and multiple-choice questions task were adopted. The results of both tasks supported the hypothesis. Meanwhile, it is also evident that the CSL learners have acquired some usage of zero anaphora in their Chinese discourse as the usage of zero anaphora was more frequent when speaking Chinese than English.

Description
This paper explains what factors influence mental health issues and what type of care is provided in various countries. The countries in this study will include the United States, Japan, Ethiopia and South Africa, all of which have varying degrees of ethnic diversity, economic status and understanding of mental health issues. It discusses the specific healthcare systems in each country, as well as the attitudes and problems associated with depression and schizophrenia, two prevalent mental health disorders. This paper examines the different ways that a diagnosis is reached for schizophrenia and major depression in these different countries, as well as what methods are used for treating individuals with these disorders. It will also examine the prominent notion that schizophrenia has better outcomes in developing countries than in places that have wider medical care available. It then discusses what treatments are available in each country, as well as social constructs that exist regarding those treatments in order to understand the ways that treatments can be expanded to improve outcomes. This paper will then examine the different outcomes of these mental health disorders that are common in each country, and conclude with ideas on how to make global mental health a reality.

Description
The study examines cross-cultural perceptions of wastewater reuse from 282 participants from four global sites representing varied levels of socio-economic and political development from the Global North and Global South: Spain, New Zealand, Fiji, and Guatemala. The data comes from the Global Ethnohydrology Survey conducted by the School of Human Evolution and Social Change during the summer of 2013. The Global Ethnohydrology Study is a transdisciplinary multi-year research initiative that examines the range of variation in local ecological knowledge of water issues, also known as "ethnohydrology." Participants were asked about their willingness, level of disgust, and concern with using treated wastewater for various daily activities. Additionally, they were asked to draw schematic representations of how wastewater should be treated to become drinkable again. Using visual content analysis, the drawings were coded for a variety of treatment levels and specific treatment processes. Conclusions about the perceived health implications from wastewater reuse that can stem from drinking treated wastewater were made. The relationship between humans and wastewater is one that has many direct social and health impacts on communities at large. In reaction to global limitations of freshwater, wastewater serves as a valuable resource to tap into. This research examines the cross-cultural public health concerns about treated wastewater in order to draw conclusions that can aid in strategic implementation of advocacy and public education about wastewater reuse.

Description
Mammals with a habitually orthograde trunk posture possess a more anterior foramen magnum than mammals with non-orthograde trunk postures. Russo & Kirk (2013) also found that bipedal orthograde mammals possess a more anteriorly placed foramen magnum than those that are just habitually orthograde. This finding has allowed us to use foramen magnum position as a predictor of trunk posture in early hominins. This prompts more research of how the other landmarks on the cranial base move in relation to this shift in foramen magnum positioning. I collected landmark data on images of 125 mammalian basicrania spanning 41 species that differed in trunk posture. Using Procrustes and Principal Components Analysis (PCA), I attempted to evaluate the effects of trunk posture on basicranial morphology, primarily focusing on the placement of the carotid and jugular foramina. The results supported Russo and Kirk's finding of a more anterior foramen magnum placement in orthograde mammals; in addition, the results displayed correlations between foramen magnum position and carotid foramen position among primates and diprotodonts.

Description
This project explores a variety of ways of framing the problem of obesity, beginning with a multidisciplinary assessment of genetic, environmental, cultural, nutritional, and socioeconomic factors involved in the structure and the consequences of each frame. How obesity is framed as a problem has a profound impact on the kinds of solutions that may be deemed scientifically appropriate. But frames are not entirely evidence-based, inasmuch as political and moral values infuse debates about the nature of obesity. Drawing on interdisciplinary resources from bioethics and the philosophy of science, I strive to offer strategic insight in to how to navigate the complexity of these issues.
