Variation Among Populations In The Immune Protein Composition Of Mother's Milk Reflects Subsistence Pattern, Laura D. Klein, Jincui Huang, Elizabeth A. Quinn, Melanie A. Martin, Alicia A. Breakey, Michael Gurven, Hillard Kaplan, Claudia Valeggia, Grazyna Jasienska, Brooke Scelza, Carlito B. Lebrilla, Katie Hinde

Lay Summary: Adaptive immune proteins in mothers’ milk are more variable than innate immune proteins across populations and subsistence strategies. These results suggest that the immune defenses in milk are shaped by a mother’s environment throughout her life.

Background and objectives: Mother’s milk contains immune proteins that play critical roles in protecting the infant from infection and priming the infant’s developing immune system during early life. The composition of these molecules in milk, particularly the acquired immune proteins, is thought to reflect a mother’s immunological exposures throughout her life. In this study, we examine the composition of innate …

A Bit Like Cash: Understanding Cash-For-Bitcoin Transactions Through Individual Vendors, Stephanie J. Robberson, Mark R. Mccoy

Journal of Digital Forensics, Security and Law

As technology improves and economies become more globalized, the concept of currency has evolved. Bitcoin, a cryptographic digital currency, has been embraced as a secure and convenient type of money. Due to its security and privacy for the user, Bitcoin is a good tool for conducting criminal trades. The Financial Crimes Enforcement Network (FinCEN) has regulations in place to make identification information of Bitcoin purchasers accessible to law enforcement, but enforcing these rules with cash-for-Bitcoin traders is difficult. This study surveyed cash-for-Bitcoin vendors in Oklahoma, Texas, Arkansas, Missouri, Kansas, Colorado, and New Mexico to determine personal demographic information, knowledge of …

Marital Violence And Fertility In A Relatively Egalitarian High-Fertility Population, Jonathan Stieglitz, Benjamin C. Trumble, Hillard Kaplan, Michael Gurven

ESI Publications

Ultimate and proximate explanations of men’s physical intimate partner violence (IPV) against women have been proposed. An ultimate explanation posits that IPV is used to achieve a selfish fitness-relevant outcome, and predicts that IPV is associated with greater marital fertility. Proximate IPV explanations contain either complementary strategic components (for example, men’s desire for partner control), non-strategic components (for example, men’s self-regulatory failure), or both strategic and non-strategic components involving social learning. Consistent with an expectation from an ultimate IPV explanation, we find that IPV predicts greater marital fertility among Tsimané forager-horticulturalists of Bolivia (n = 133 marriages, 105 women). This …

Monogamy appears to have become the predominant human mating system with the emergence of highly unequal agricultural populations that replaced relatively egalitarian horticultural populations, challenging the conventional idea—based on the polygyny threshold model—that polygyny should be positively associated with wealth inequality. To address this polygyny paradox, we generalize the standard polygyny threshold model to a mutual mate choice model predicting the fraction of women married polygynously. We then demonstrate two conditions that are jointly sufficient to make monogamy the predominant marriage form, even in highly unequal societies. We assess if these conditions are satisfied using individual-level data from 29 human …

Narcocorridos: Music, Defiance, And Violence In Transnational Contexts, Nallely G Murguia

Capstone Projects and Master's Theses

This research aims to explain and understand the effects that the music genre known as narcocorrido has on society, politics, and culture in Mexico and the United States. It provides a background on the history of narcocorridos and how it came be known as a symptom of the ongoing violence in Mexico. The Movimiento Alterado is also explored in this research project, as a product of narcocorrido singers who came together to glorify violence. A global aspect plays a big role in researching this topic as globalization and transnationalism reveal the complexity of politics, economics, and culture and its effects …

Furs: Functionality, Fashion, And Franchise, Jenna Q. Detweiler

Environment and Sustainability Honors Papers

Animal furs have been used in various manners through human history. Early humans cut crude shawls for warmth, and with the development of tools such as needles, closer-fitting clothing such as fur pants became possible. As time went on, products such as wool and cotton were used for clothing and, with fur alternatives, furs were reserved for the ultra-wealthy in some cultures. The image of fur as a luxury item has remained ever since, but simultaneously fur has become more accessible to the general public. Meanwhile, animal rights movements have successfully dampened interest in fur in some countries and communities. …

Land-Use And Land-Ownership Changes In Usoma Village, Kenya, Ernest Tan

Independent Study Project (ISP) Collection

This study attempted to find out how land-use activities and land-ownership patterns have changed since land adjudication in Usoma Village, a peri-urban community on the fringe of Kisumu City. The methods used were photo-observation and geo-tagging based on walkabouts onsite, documentary analysis of maps obtained from the Ministry of Lands, interviews with key authority figures, independent experts and community leaders, and interviews as well as focus-group discussions with community members. In terms of land ownership, it was found that subdivisions of land, both formal and informal, had been common over the period. Land transfers based on compulsory acquisition and investment …

Pearl Lagoon's White Lobster: The Societal, Economic, Political And Autonomous Effects, Rafely Palacios

Independent Study Project (ISP) Collection

The Atlantic Coast of Nicaragua is home to the greatest number of impoverished individuals in the country. However, the people of Pearl Lagoon - a municipality in the South Caribbean Coast Autonomous Region - have found a way to escape their poor economic situations.

Due to the municipality’s close proximity to drug routes utilized by Colombian cartels and to the country itself, community members have turned to the drug trade in hopes of pursuing financial secureness. With the introduction of the “white lobster” or cocaine packets, the community as a whole has transformed its social, economic, and political spheres. In …

Sex Differences In Political Leadership In An Egalitarian Society, Christopher Von Rueden, Sarah Alami, Hillard Kaplan, Michael Gurven

ESI Publications

We test the contribution of sex differences in physical formidability, education, and cooperation to the acquisition of political leadership in a small-scale society. Among forager-farmers from the Bolivian Amazon, we find that men are more likely to exercise different forms of political leadership, including verbal influence during community meetings, coordination of community projects, and dispute resolution. We show that these differences in leadership are not due to gender per se but are associated with men’s greater number of cooperation partners, greater access to schooling, and greater body size and physical strength. Men’s advantage in cooperation partner number is tied to …

Low Perceived Control Over Health Is Associated With Lower Treatment Uptake In A High Mortality Population Of Bolivian Forager-Farmers, Sarah Alami, Jonathan Stieglitz, Hillard Kaplan, Michael Gurven

ESI Publications

Indigenous people worldwide suffer from higher rates of morbidity and mortality than neighboring populations. In addition to having limited access to public health infrastructure, indigenous people may also have priorities and health perceptions that deter them from seeking adequate modern healthcare. Here we propose that living in a harsh and unpredictable environment reduces motivation to pursue deliberate, costly action to improve health outcomes. We assess whether variation in Health Locus of Control (HLC), a psychological construct designed to capture self-efficacy with respect to health, explains variation in treatment uptake behavior among Tsimane Amerindians (N=690; age range: 40–89 years; 55.8% female; …

Crafting Local Food Narratives With Immigrant Voices: Participatory Ethnography Among Somali Bantu Farmers In West Denver, Raymond Alexander Pang

Electronic Theses and Dissertations

In 2013, a non-profit, Re:Vision, established the Ubuntu Farm to work with the local Somali Bantu refugee population. It was supposed to improve access to fresh produce, offer educational opportunities, skill training and more. Early on in 2014, it became clear Re:Vision was not delivering on its promises, and by 2015 the farm had ceased to exist. Using participant observation, interviews with farm participants and staff and a review of publicly accessible financial documents, I argue that Re:Vision maintained a conflict of mission, which contributed to their farms' failings, despite their ability to grow plenty of vegetables. From there, I …

Residential Solar In Washington State, Sam Pfeifer

All Master's Theses

Electricity generated through residential solar provides a low carbon source of electricity. However, diffusion of residential solar remains low across the United States. Growing this diffusion takes an understanding of localized uptake trends, which can focus policy and business efforts to help increase residential solar market penetration. This is the first research to investigate residential solar uptake in Washington State and to examine environmental education as a potential driver of residential solar uptake. Through a snapshot analysis which considers environmental, economic, education, and cultural variables the present research fills this gap. Triangulated results include mapping of variables, ordinary-least squares multiple …

Information Transmission And The Oral Tradition: Evidence Of A Late-Life Service Niche For Tsimane Amerindians, Eric Schniter, Nathaniel T. Wilcox, Bret A. Beheim, Hillard S. Kaplan, Michael Gurven

ESI Publications

Storytelling can affect wellbeing and fitness by transmitting information and reinforcing cultural codes of conduct. Despite their potential importance, the development and timing of storytelling skills, and the transmission of story knowledge have received minimal attention in studies of subsistence societies that more often focus on food production skills. Here we examine how storytelling and patterns of information transmission among Tsimane forager-horticulturalists are predicted by the changing age profiles of storytellers’ abilities and accumulated experience. We find that storytelling skills are most developed among older adults who demonstrate superior knowledge of traditional stories and who report telling stories most. We …

Man And Land: Competing Ontologies, Colonial Legacies, And The Quest For Food Sovereignty, Savannah Smith

Independent Study Project (ISP) Collection

Land is an ontological reality, which is at the center of different relationships to land. These relationships are situated in and a product of historical and spatial process that have an under lying power geometry. These different understandings of land tenure can create conflict when they intersect with competing interests in the same space. In Cameroon, this is currently the case in the form of large-scale land acquisitions, which often conflict with local communities as multinational corporations and local elites acquire land concessions with facilitation by the government in the name of development. This paper aims to understand this issue …

Perspectives On Language From Street Produce Vendors In Cape Town: An Examination Of Education, Trading, And Development In The Informal Sector, Hannah Oldham

Independent Study Project (ISP) Collection

Language is vital for the functioning of societies, from education to economic interactions. Language of education presents challenges in Africa due to colonial linguistic legacies and the diversity of indigenous African languages. While education trains learners for work in the formal economy, the South African formal cannot absorb all the available labor. The informal economy therefore provides vital work and income to millions of South Africans and immigrants. Language use in the informal sector was studied, including the education and work traders had before working as street produce vendors.

Six interviews were conducted: two near the Cape Town taxi rank, …

Luchadoras: Resistencias Contra La Violencia De Género Por Las Mujeres En La Región De San Ramón, Olivia "Livey" Beha

Independent Study Project (ISP) Collection

This qualitative study describes the dynamic resiliency-building process against gender-based violence in two rural coffee-producing communities in the region of San Ramon, Nicaragua. It examines the methods and efficacy of economic empowerment and educational interventions facilitated by the Union of Agricultural Cooperatives Augusto Cesar Sandino (UCA San Ramón) in addressing gender inequality, preventing gender-based violence, and increasing access to resources for women in the cooperatives of El Privilegio and Danilo Gonzales. This complex ecology, comprised of the interactions between women, their communities, available resources, and institutions, is assessed through the lens of women’s individual perspectives as they engage in three …

The Virtualism Of “Capacity Building” Workshops In Indigenous Amazonia, Laura Mentore

Cultural and Philosophical Inquiry Articles

Sustainable development and conservation NGOs in Amazonia often hold workshops in which they task indigenous communities with various activities in the name of “capacity building.” People tend to perform these tasks despite often finding them to be flawed, demeaning, or based on erroneous assumptions about their lifeways and perspectives. Workshop organizers, for their part, tend to view local participation in itself as a straightforward indicator of a successful workshop to the neglect of a more complex picture. These combined tendencies contribute to expectations on both sides being partially fulfilled at best, but due to asymmetrical power distributions, can have disproportionately …

Land Insecurity In Gulu, Uganda: A Clash Between Culture And Capitalism, Zachary Slotkin

Independent Study Project (ISP) Collection

This paper presents the causes and consequences of land insecurity in Gulu, Uganda. In order to address this important and often sensitive issue, the paper analyzes the role of the Lord’s Resistance Army (LRA) insurgency and the government’s policy of forced encampment during the insurgency in contributing to land insecurity, causing widespread displacement among former internally displaced persons (IDPs). It further explores the importance of land ownership in providing economic productivity to rural landowners, as well as the nature of customary land tenure in Acholi culture and the government’s efforts to privatize communal land, to give a background on the …

Making The Gigantic Suburban Residential Complex In Beijing: Political Economy Processes And Everyday Life In The 2010s, Pengfei Li

Dissertations, Theses, and Capstone Projects

Suburbanization is an ongoing development process in China. Hundreds of thousands of construction projects are being undertaken in outskirts of most Chinese cities, despite the increasing domestic and international concerns over China’s housing oversupply (Xu, 2010; Gough, 2015; Li, 2015). The suburbanization of China, however, is fundamentally different from the suburbanization of most Western countries, especially the United States, whose massive post-war suburbanization took place as a continuation of its pre-war industrialization and urbanization movements. In the Chinese context, suburbanization is the process of urbanization as well—urbanization and suburbanization have been promoted simultaneously since the 1990s. It is …

The aim of this research is to provide perspective on Bridges Out of Poverty’s contribution to the understanding of poverty in the United States and its potential as an antipoverty intervention. It does so first through an exploration of the historical and current discussion on poverty and anti-poverty interventions in the United States, followed by research on the Bridges model itself and its implementation in Kennett Square. This latter research includes content …

A Tanzanian Woman's Place Is On Top: An Exploration Of Women's Participation In Kilimanjaro's Trekking Tourism Industry, Margeaux Prinster

Sustainability and Social Justice

While high poverty rates persist for women in Tanzania, the growing trekking tourism industry surrounding Mount Kilimanjaro and its resulting demand for labor presents these impoverished women with a potential avenue for economic empowerment. This paper examines the national and local realities of women’s work in Tanzania, analyzing culturally informed gendered patterns of employment against the colonial and sexist histories of tourism and commercial mountaineering on Mount Kilimanjaro to identify barriers to women’s economic participation in Kilimanjaro’s trekking tourism industry. This analysis is followed by a cross-cultural comparison with Nepal, focusing specifically on women’s barriers to participation in commercial mountaineering, …

Coronary Atherosclerosis In Indigenous South American Tsimane: A Cross-Sectional Cohort Study, Hillard Kaplan, Randall C. Thompson, Benjamin C. Trumble, L. Samuel Wann, Adel H. Allam, Bret Beheim, Bruno Frohlich, M. Linda Sutherland, James D. Sutherland, Jonathan Stieglitz, Daniel Eid Rodriguez, David E. Michalik, Chris J. Rowan, Guido P. Lombardi, Ram Bedi, Angela R. Garcia, James K. Min, Jagat Narula, Caleb E. Finch, Michael Gurven, Gregory S. Thomas

ESI Publications

Background—Conventional coronary artery disease risk factors might potentially explain at least 90% of the attributable risk of coronary artery disease. To better understand the association between the pre-industrial lifestyle and low prevalence of coronary artery disease risk factors, we examined the Tsimane, a Bolivian population living a subsistence lifestyle of hunting, gathering, fishing, and farming with few cardiovascular risk factors, but high infectious inflammatory burden.

Methods—We did a cross-sectional cohort study including all individuals who self-identified as Tsimane and who were aged 40 years or older. Coronary atherosclerosis was assessed by coronary artery calcium (CAC) scoring done with …

The Tsimane Health And Life History Project: Integrating Anthropology And Biomedicine, Michael Gurven, Jonathan Stieglitz, Benjamin C. Trumble, Aaron D. Blackwell, Bret Beheim, Helen Davis, Hillard Kaplan, Paul L. Hooper

ESI Publications

The Tsimane Health and Life History Project, an integrated bio-behavioral study of the human life course, is designed to test competing hypotheses of human life-history evolution. One aim is to understand the bidirectional connections between life history and social behavior in a highfertility, kin-based context lacking amenities of modern urban life (e.g. sanitation, banks, electricity). Another aim is to understand how a high pathogen burden influences health and well-being during development and adulthood. A third aim addresses how modernization shapes human life histories and sociality. Here we outline the project’s goals, history, and main findings since its inception in 2002. …

Horticultural Activity Predicts Later Localized Limb Status In A Contemporary Pre-Industrial Population, Jonathan Stieglitz, Benjamin C. Trumble, Hillard Kaplan, Michael Gurven

ESI Publications

Objectives—Modern humans may have gracile skeletons due to low physical activity levels and mechanical loading. Tests using prehistoric skeletons are limited by the inability to assess behaviour directly, while modern industrialized societies possess few socio-ecological features typical of human evolutionary history. Among Tsimane forager-horticulturalists, we test whether greater activity levels and, thus, increased loading earlier in life are associated with greater later-life bone status and diminished age-related bone loss.

Materials and Methods—We used quantitative ultrasonography to assess radial and tibial status among adults aged 20+ years (mean±SD age=49±15; 52% female). We conducted systematic behavioural observations to assess earlier-life …

Human Grooming In Comparative Perspective: People In Six Small-Scale Societies Groom Less But Socialize Just As Much As Expected For A Typical Primate, Adrian V. Jaeggi, Karen Kramer, Raymond Hames, Evan J. Kiely, Cristina Gomes, Hillard Kaplan, Michael Gurven

ESI Publications

Objectives—Grooming has important utilitarian and social functions in primates but little is known about grooming and its functional analogues in traditional human societies. We compare human grooming to typical primate patterns to test its hygienic and social functions.

Materials and Methods—Bayesian phylogenetic analyses were used to derive expected human grooming time given the potential associations between grooming, group size, body size, terrestriality, and several climatic variables across 69 primate species. This was compared against observed times dedicated to grooming, other hygienic behavior and conversation among the Maya, Pumé, Sanöma, Tsimane’, Yanomamö, and Ye’kwana (mean number of behavioral scans …

The Failure Of Post-War Reconstruction In Jaffna, Sri Lanka: Indebtedness, Caste Exclusion And The Search For Alternatives, Ahilan Kadirgamar

Dissertations, Theses, and Capstone Projects

Reconstruction of contemporary war-torn societies can lead to further dispossession and social exclusion, particularly through neoliberal development policies and financialized indebtedness. This dissertation analyses post-war reconstruction of the Jaffna District in the Northern Province of Sri Lanka after the end of a brutal three decade long civil war in May 2009, through a survey and ethnographic study of one village, Pathemany and its oppressed caste quarter, Bharathy Veethy. Drawing on a study of Pathemany village on agrarian change before the war, this study addresses contemporary questions about land, rural incomes, rural debt and caste structure. The study evaluates reconstruction policies …

Cognitive Performance Across The Life Course Of Bolivian Forager-Farmers With Limited Schooling, Michael Gurven, Eric Fuerstenberg, Benjamin C. Trumble, Jonathan Stieglitz, Bret Beheim, Helen Davis, Hillard Kaplan

ESI Publications

Cognitive performance is characterized by at least two distinct life course trajectories. Many cognitive abilities (e.g. “effortful processing” abilities including fluid reasoning, and processing speed) improve throughout early adolescence and start declining in early adulthood, while other abilities (e.g. “crystallized” abilities like vocabulary breadth) improve throughout adult life, remaining robust even at late ages. Although schooling may impact performance and cognitive “reserve”, it has been argued that these age patterns of cognitive performance are human universals. Here we examine age patterns of cognitive performance among Tsimane forager-horticulturalists of Bolivia, and test whether schooling is related to differences in cognitive performance …

Patterns Of Enslavement And Economic Oppression Of Central Virginia, Hannah Bedwell

Undergraduate Research Posters

I address how anthropologists can identify the patterns and development of slavery and economic oppression through archaeology and the visualization of Virginia enslavement. I focus on the enslaved people of James Madison's Montpelier. I use 3D modeling as a foundation for integrating enhanced visuals with the goal of presenting a tangible understanding of the enslaved individuals in relation to the artifacts and history of the archaeological sites. I intend to show a common theme in economic oppression by comparing modern themes in slavery and examining Fraser D. Neiman's synthesis of the evolutionary perspective of slavery, and how little has changed …
