Household Task Delegation Among High-Fertility Forager-Horticulturalists Of Lowland Bolivia, Jonathan Stieglitz, Michael Gurven, Hillard Kaplan, Paul L. Hooper

ESI Publications

Human kin cooperation is universal, leading researchers to label humans as “cooperative breeders.” Despite widespread interest in human cooperation, there has been no systematic study of how household economic decision making occurs. We document age and sex profiles of task delegation by parents to children ages 4–18 among Bolivian forager-horticulturalists. We test for sex differences in the probability of delegation and examine whether tasks are more likely delegated as household labor demand increases. We also test whether food acquisition tasks are more likely delegated to higher producers.We find mixed support for the prediction that girls are more likely delegated domestic …

Physical Activity And Modernization Among Bolivian Amerindians, Michael Gurven, Adrian V. Jaeggi, Hillard Kaplan, Daniel Cummings

ESI Publications

Background: Physical inactivity is a growing public health problem, and the fourth leading risk factor for global mortality. Conversely, indigenous populations living traditional lifestyles reportedly engage in vigorous daily activity that is protective against non-communicable diseases. Here we analyze physical activity patterns among the Tsimane, forager-horticulturalists of Amazonian Bolivia with minimal heart disease and diabetes. We assess age patterns of adult activity among men and women, test whether modernization affects activity levels, and examine whether nascent obesity is associated with reduced activity.

Methods and Findings: A factorial method based on a large sample of behavioral observations was employed …

Shared Responsibility In A Multispecies Playground, Marcus Baynes-Rock

Between the Species

While conducting research on urbanised hyenas in Harar, Ethiopia, I was approached by a young hyena named Willi. In contrast to other hyenas, who tolerated my presence but otherwise had little interest in me, Willi insisted on some kind of engagement. Through biting, chase play, combing, following and standing by one other, Willi and I went beyond our species limitations and created an improvised intersubjectivity based on a will to understand. However, our friendship led to some harmful consequences for which I felt responsible. This led me to question the ethics of engagement with non-humans: if unforeseen harms can result …

Culturally Responsive Methodologies At Work In Education Settings, Mere Berryman, Suzanne Soohoo, Ann Nevin, Te Arani Barrett, Therese Ford, Debora Joy Nodelman, Norma Valenzuela, Anna Wilson

Education Faculty Articles and Research

Purpose – The purpose of this paper is to describe culturally responsive methodology as a way to develop researchers. The aim is to illuminate the dimensions of culturally responsive methodology such as cultural and epistemological pluralism, deconstruction of Western colonial traditions of research, and primacy of relationships within culturally responsive dialogic encounters. An overarching question is: “How can we maintain the original integrity of both participants and researchers and their respective cultures and co-construct at the same time something new?”

Design/methodology/approach – Five case study narratives are described in order for readers to understand the range and types of studies …

How Universal Is The Big Five? Testing The Five-Factor Model Of Personality Variation Among Forager-Farmers In The Bolivian Amazon, Michael Gurven, Christopher Von Rueden, Maxim Massenkoff, Hillard Kaplan, Marino Lero Vie

ESI Publications

The five-factor model (FFM) of personality variation has been replicated across a range of human societies, suggesting the FFM is a human universal. However, most studies of the FFM have been restricted to literate, urban populations, which are uncharacteristic of the majority of human evolutionary history. We present the first test of the FFM in a largely illiterate, indigenous society. Tsimane forager–horticulturalist men and women of Bolivia (n = 632) completed a translation of the 44-item Big Five Inventory (Benet-Martínez & John, 1998), a widely used metric of the FFM. We failed to find robust support for the FFM, based …

Modernization, Sexual Risk-Taking, And Gynecological Morbidity Among Bolivian Forager-Horticulturalists, Jonathan Stieglitz, Aaron D. Blackwell, Raúl Quispe Gutierrez, Edhitt Cortez Linares, Michael Gurven, Hillard Kaplan

ESI Publications

Sexual risk-taking and reproductive morbidity are common among rapidly modernizing populations with little material wealth, limited schooling, minimal access to modern contraception and healthcare, and gendered inequalities in resource access that limit female autonomy in cohabiting relationships. Few studies have examined how modernization influences sexual risk-taking and reproductive health early in demographic transition. Tsimane are a natural fertility population of Bolivian forager-farmers; they are not urbanized, reside in small-scale villages, and lack public health infrastructure. We test whether modernization is associated with greater sexual risk-taking, report prevalence of gynecological morbidity (GM), and test whether modernization, sexual risk-taking and parity are …

Review Of Every Twelve Seconds: Industrialized Slaughter And The Politics Of Sight. By Timothy Pachirat., Donald D. Stull

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

In June 2004, political scientist Timothy Pachirat went to work on the killfloor of an unnamed beef slaughterhouse in Omaha, Nebraska. He started out as a "liver hanger" in the cooler. There carcasses hang before being sent to the fabrication floor where "hundreds of handheld knives and saws reinvent chilled half-carcasses as steaks, rounds, and roasts that are then boxed and shipped to distributors and retailers around the world." For four days he worked in the chutes, driving cattle to the knocking box to be stunned, as required by the Humane Slaughter Act, before being turned into meat. Then for …

Why Do Women Have More Children Than They Want? Understanding Differences In Women's Ideal And Actual Family Size In A Natural Fertility Population, Lisa Mcallister, Michael Gurven, Hillard Kaplan, Jonathan Stieglitz

ESI Publications

Objectives—We develop and test a conceptual model of factors influencing women’s ideal family size (IFS) in a natural fertility population, the Tsimane of Bolivia. The model posits affects of socioecology, reproductive history, maternal condition, and men’s IFS. We test three hypotheses for why women may exceed their IFS despite experiencing socioeconomic development: (H1) limited autonomy; (H2) improved maternal condition; and (H3) low returns on investments in embodied capital.

Methods—Women’s reproductive histories and prospective fertility data were collected from 2002 to 2008 (n = 305 women). Semistructured interviews were conducted with Tsimane women to study the perceived value of …

Fatty Acid Composition In The Mature Milk Of Bolivian Forager-Horticulturalists: Controlled Comparisons With A Us Sample, Melanie A. Martin, William D. Lassek, Steven J. C. Gaulin, Rhobert W. Evans, Sheela S. Geraghty, Barbara S. Davidson, Ardythe L. Morrow, Hillard Kaplan, Michael Gurven

ESI Publications

Breast milk fatty acid (FA) composition varies greatly among individual women, including in percentages of the long-chain polyunsaturated FAs (LCPUFA) 20:4n-6 (arachidonic acid, AA) and 22:6n-3 (docosahexaenoic acid, DHA), which are important for infant neurological development. It has been suggested that owing to wide variation in milk LCPUFA and low DHA in Western diets, standards of milk FA composition should be derived from populations consuming traditional diets. We collected breast milk samples from Tsimane women at varying lactational stages (6–82 weeks). The Tsimane are an indigenous, natural fertility, subsistence-level population living in Amazonia Bolivia. Tsimane samples were matched by lactational …

From The Womb To The Tomb: The Role Of Transfers In Shaping The Evolved Human Life History, Michael Gurven, Jonathan Stieglitz, Paul L. Hooper, Cristina Gomes, Hillard Kaplan

ESI Publications

Humans are the longest living and slowest growing of all primates. Although most primates are social, humans are highly cooperative and social in ways that likely co-evolved with the slow human life history. In this paper we highlight the role of resource transfers and non-material assistance within and across generations in shaping low human mortality rates. The use of complex cooperative strategies to minimize risk is a necessary precursor for selecting further reductions in mortality rate in late adulthood. In conjunction with changes in the age-profile of production, the impacts of resource transfers and other forms of cooperation on reducing …

Conversion Theory Through The Cognitive Science Of Religion Lense In A Christian-Muslim Context, Jennifer A. Garcia

Scripps Senior Theses

The Cognitive Science of Religion (CSR) in recent years is beginning to become more popular. This project evolves around the development of the field as well as critiques of the field. Because of the interdisciplinary nature of CSR, it lends an interesting way to understand religion as well as religious experiences. One of those religious experiences, conversion, is examined and explored through the use of conversion narratives from western women who were formally Christian but converted to Islam. Many themes arise out of this research that paves the way for trying to understand religious experiences. Overall, the project focuses on …

Infidelity, Jealousy, And Wife Abuse Among Tsimane Forager-Farmers: Testing Evolutionary Hypotheses Of Marital Conflict, Jonathan Stieglitz, Michael Gurven, Hillard Kaplan, Jeffrey Winking

ESI Publications

What causes marital conflict, and which marital conflicts are more likely to result in men’s violence against their wives? It has long been argued that men’s jealousy over women’s infidelity is the strongest impetus to men’s lethal and non-lethal violence against female partners. Less is known about the extent to which women’s jealousy over men’s infidelity precipitates men’s violence against female partners. Husbands are more likely than wives to commit infidelity, and men and women report a similar frequency and intensity of jealous emotions during recalls of potential infidelity. If men are likely to use time and resources for pursuit …

A Queer Vegan Manifesto, Rasmus R. Simonsen

Human Health Collection

What does it mean for a person to declare her or his veganism to the world? How does the transition from one diet to another impact one’s sense of self? Veganism challenges the foundational character of how we “act out” our selves—not least of all in the context of sexuality and gender. In my paper, I am thus interested in the potential of veganism to disrupt the “natural” bond between gender formations and the consumption of animal products, as this relates to social and cultural genealogies. Consequently, I will explore a queer form of veganism that affirms the radical impact …

Binding Ochre To Theory, Simone E. Nibbs

Pomona Senior Theses

Widely found throughout the archaeological and artistic records in capacities ranging from burial contexts to early evidence of artistic expression, red ochre has been studied in archaeological and art conservationist communities for decades. Despite this, literature discussing binders is disparate and often absent from accessible arenas. Red ochre is important historically because its use can be used to help further the understanding of early humans, their predecessors, and their cognitive capabilities. However, there is not much written speculation on the processes involved in binder selection, collection, and processing. Based on the idea of these three activities associated with binders, I …

Xrf And The Corrosion Environment At Camp Lawton: A Comprehensive Study Of The Archeological Microenvironment Of A Civil War Prison Camp, Amanda L. Morrow

College of Graduate Studies: Theses & Dissertations

Author's abstract: Handheld X Ray Fluorescence (XRF) technology is a new and emerging method in the field of archeology. This thesis discusses the results of XRF comparative analysis and comparative chemical analysis between a given ferrous metallic artifact's corrosion environment (the surrounding soil matrix) and the subsequent corrosion products formed on the artifact. The hypothesis is that the data will demonstrate a chemical correlation between the two. Iron and chlorine are the two major elements discussed in the study. The artifacts in the sample set have been collected from Camp Lawton (9JS1), a Confederate Prison for Union Soldiers located in …

Toward A Holistic Interdisciplinary Model Of Human Being: A Hebraic-Christian Perspective Of The Human Observer And Its Beneficial Impact On The Theology-And-Science Dialogue, Society, And The Environment, Karen K. Abrahamson

Dissertations

Problem

A challenge faced by the theology-and-science dialogue is how to effectively communicate across disciplinary lines. The community assumes that there is a methodology or cluster of methodologies that allows for interdisciplinary conversation to take place. However, the community is not in agreement about how this process should occur or the hermeneutical principles that should guide it. Is it possible to surmount the problem of methodological compatibility and to generate mutually beneficial and fruitful dialogue through seeking a point of commonality between all the disciplines of the theology-and-science dialogue?

Purpose

The purpose of this dissertation is to discover a philosophical …

Evidence For A Peak Shift In A Humoral Response To Helminths: Age Profiles Of Ige In The Shuar Of Ecuador, The Tsimane Of Bolivia, And The U.S. Nhanes, Aaron D. Blackwell, Michael D. Gurven, Lawrence S. Sugiyama, Felicia C. Madimenos, Melissa A. Liebert, Melanie A. Martin, Hillard Kaplan, J. Josh Snodgrass

ESI Publications

Background: The peak shift model predicts that the age-profile of a pathogen’s prevalence depends upon its transmission rate, peaking earlier in populations with higher transmission and declining as partial immunity is acquired. Helminth infections are associated with increased immunoglobulin E (IgE), which may convey partial immunity and influence the peak shift. Although studies have noted peak shifts in helminths, corresponding peak shifts in total IgE have not been investigated, nor has the age-patterning been carefully examined across populations. We test for differences in the agepatterning of IgE between two South American forager-horticulturalist populations and the United States: the Tsimane …

Inflammatory Gene Variants In The Tsimane, An Indigenous Bolivian Population With A High Infectious Load, Sarinnapha Vasunilashorn, Caleb E. Finch, Eileen M. Crimmins, Suvi A. Vikman, Jonathan Stieglitz, Michael Gurven, Hillard Kaplan, Hooman Allayee

ESI Publications

The Tsimane of lowland Bolivia are an indigenous forager-farmer population living under conditions resembling pre-industrial European populations, with high infectious morbidity, high infection and inflammation, and shortened life expectancy. Analysis of 917 persons ages 5 to 60+ showed that allele frequencies of 9 SNPs examined in the apolipoprotein E (apoE), C-reactive protein (CRP), and interleukin-6 (IL-6) genes differed from some European, African, and north Asian-derived populations. The apoE2 allele was absent, whereas four SNPs related to CRP and IL-6 were monomorphic: CRP (rs1800947, rs3093061, and rs3093062) and IL-6 (rs1800795). No significant differences in apoE, CRP, and IL-6 variants across age …

Designing A School Garden Space That Emphasizes Children's Wants And Uses Permaculture Design Methods, Mikhaela Mullins

Department of Environmental Studies: Undergraduate Student Theses

A case study was organized at Saratoga Elementary school in Lincoln, Nebraska to obtain data on what children desire in a garden space. To collect this data a school garden space was constructed and an after school garden club was implemented. Students who participated in the after school garden club partook in the study by drawing their ideal garden. Elements that the subjects drew were identified and categorized into ‘highly desired’ and ‘somewhat desired’.

These elements were then incorporated into a proposed garden design plan for Saratoga. The proposal plan uses Permaculture design methods to emphasize sustainability.

Cognitive Relatives Yet Moral Strangers?, Judith Benz-Scharzberg, Andrew Knight

Animal Welfare Collection

This article provides an empirically based, interdisciplinary approach to the following two questions: Do animals possess behavioral and cognitive characteristics such as culture, language, and a theory of mind? And if so, what are the implications, when long-standing criteria used to justify differences in moral consideration between humans and animals are no longer considered indisputable? One basic implication is that the psychological needs of captive animals should be adequately catered for. However, for species such as great apes and dolphins with whom we share major characteristics of personhood, welfare considerations alone may not suffice, and consideration of basic rights may …

Father Death And Adult Success Among The Tsimane: Implications For Marriage And Divorce, Jeffrey Winking, Michael Gurven, Hillard Kaplan

ESI Publications

Human fathers are heavily involved in the rearing of children around the world. While there is great cross-cultural variation, the father is a recognizable role in all populations. This deviates from the standard mammalian pattern of little paternal investment. A logical explanation offered early by evolutionary theorists is that human fathers evolved the capacity for paternal concern because human children are remarkably needy and impose a great encumbrance on the mother (Lancaster & Lancaster, 1983; Lovejoy, 1981). Thus, fathers have greater opportunity to enhance the wellbeing of child and mother, as there is a deeper well of need to fill. …

Postnatal Dental Mineralization: A Comparative Analysis Of Dental Development Among Contemporary Populations Of The Southeastern United States, Meryle Akeara Dotson

USF Tampa Graduate Theses and Dissertations

Due to the strong genetic component of dental development, research has shown that mineralization patterns of the human dentition are relatively buffered against environmental influences that normally affect bone growth and development. It is because of this resistance to environmental factors and the continuous growth of the permanent dentition throughout childhood and adolescence that the evaluation of dental development patterns has become the preferred method of age estimation in living and deceased children.

Researchers (Harris and Mckee 1990; Tompkins 1996; Blankenship et al. 2007; Kasper et al. 2009) have suggested that the timing of dental development varies by …

Blood Lipids, Infection, And Inflammatory Markers In The Tsimane Of Bolivia, Sarinnapha Vasunilashorn, Eileen M. Crimmins, Jung Ki Kim, Jeff Winking, Michael Gurven, Hillard Kaplan, Caleb Finch

ESI Publications

Objectives—Little is known about blood cholesterol (blood-C) levels under conditions of infection and limited diet. This study examines blood-C and markers of infection and inflammation in the Tsimane of the Bolivian Amazon, indigenous forager farmers living in conditions that model preindustrial European populations by their short life expectancy, high load of infections and inflammation, and limited diets.

Methods—We use multivariate models to determine the relationships between lipid levels and markers of infection and inflammation. Adult Tsimane (N = 418, age 20–84) were characterized for blood lipids, cells, and inflammatory markers in relation to individual loads of parasites and …

The Social Strategy Game: Resource Competition Within Female Social Networks Among Small-Scale Forager-Horticulturalists, Stacey L. Rukas, Michael Gurven, Hillard Kaplan, Jeffrey Winking

ESI Publications

This paper examines social determinants of resource competition among Tsimane Amerindian women of Bolivia. We introduce a semi-anonymous experiment (the Social Strategy Game) designed to simulate resource competition among women. Information concerning dyadic social relationships and demographic data were collected to identify variables influencing resource competition intensity, as measured by the number of beads one woman took from another. Relationship variables are used to test how the affiliative or competitive aspects of dyads affect the extent of prosociality in the game. Using a mixed-modeling procedure, we find that women compete with those with whom they are quarreling over accusations of …

Gloria E. Anzaldúa’S Decolonizing Ritual De Conocimiento, Sarah S. Ohmer

Publications and Research

Gloria E. Anzaldúa’s work makes up one of the many Chican@ works that contribute another history, a history repressed by the national discourses on both sides of the border. Influenced by antecedents of U.S. Hispanic Literature who superposed “official” history with another history, Chicano activists had already enacted a retrieval of pre-conquest histories to revive their people’s historical consciousness. As Saldívar-Hull states in “Mestiza Consciousness and Politics: Gloria Anzaldúa’s Borderlands/ La frontera,” the publication of Borderlands/ La Frontera distinguished itself from the Chicano movement’s as it unveiled the curtain that hid the Aztec goddesses and kept aspects of pre-conquest history …

Negotiating New Roles, New Moralities : Ukrainian Women Physicians At A Post-Socialist Crossroad, Maryna Yevgenivna Bazylevych

Legacy Theses & Dissertations (2009 - 2024)

My dissertation discusses concepts of professionalism and morality as seen by women physicians in post-socialist Ukraine. As in many other post-socialist societies, Ukrainian women constitute the majority of the medical profession (over 70% of practicing physicians and 80% of medical students). Most of the existing literature explains this narrowly in materialist terms whereby low salary is viewed as determinant of low prestige and thus unattractiveness to men. I suggest that prestige is defined much broader in the local context. Based on ethnographic fieldwork in Central and Western Ukraine (2007-2008), I argue that the meanings of prestige carry both socialist and …

Inflammation And Infection Do Not Promote Arterial Aging And Cardiovascular Disease Risk Factors Among Lean Horticulturalists, Michael Gurven, Hillard Kaplan, Jeffrey Winking, Daniel Eid Rodriguez, Sarinnapha Vasunilashorn, Jung Ki Kim, Caleb Finch, Eileen M. Crimmins

ESI Publications

Background: Arterial aging is well characterized in industrial populations, but scantly described in populations with little access to modern medicine. Here we characterize health and aging among the Tsimane, Amazonian forager-horticulturalists with short life expectancy, high infectious loads and inflammation, but low adiposity and robust physical fitness. Inflammation has been implicated in all stages of arterial aging, atherogenesis and hypertension, and so we test whether greater inflammation associates with atherosclerosis and CVD risk. In contrast, moderate to vigorous daily activity, minimal obesity, and low fat intake predict minimal CVD risk among older Tsimane.

Methods and Findings: Peripheral arterial …

A Bioeconomic Approach To Marriage And The Sexual Division Of Labor, Michael Gurven, Jeffrey Winking, Hillard Kaplan, Christopher Von Rueden, Lisa Mcallister

ESI Publications

Children may be viewed as public goods whereby both parents receive equal genetic benefits yet one parent often invests more heavily than the other.We introduce a microeconomic framework for understanding household investment decisions to address questions concerning conflicts of interest over types and amount of work effort among married men and women. Although gains and costs of marriage may not be spread equally among marriage partners, marriage is still a favorable, efficient outcome under a wide range of conditions. This bioeconomic framework subsumes both cooperative and conflictive views on the sexual division of labor. We test hypotheses concerning marriage markets, …

The Multiple Dimensions Of Male Social Status In An Amazonian Society, Christopher Von Rueden, Michael Gurven, Hillard Kaplan

ESI Publications

"In all human societies, individuals differ in social status depending upon their age and personal ability (Sahlins, 1958; Service, 1971). In laboratory-based small group studies, status hierarchies emerge spontaneously (Bass, 1954; Campbell et al., 2002; Kalma, 1991). Even among “egalitarian” foragers, who are characterized by widespread resource sharing (Kaplan & Gurven, 2005; Winterhalder, 1986) and some degree of status-leveling (Cashdan, 1980), certain individuals consume more resources, get the best pick of mates, and take a more central role in group decision-making (Boehm, 1999; Trigger, 1985; Wiessner, 1996). Whether implicit or overt, classification by social status is a human universal. While …

Aging And Inflammation In Two Epidemiological Worlds, Michael Gurven, Hillard Kaplan, Jeffrey Winking, Caleb Finch, Eileen M. Crimmins

ESI Publications

Humans evolved in a world with high levels of infection resulting in high mortality across the life span and few survivors to advanced ages. Under such conditions, a strong acute-phase inflammatory response was required for survival; however, inflammatory responses can also promote chronic diseases of aging. We hypothesize that global historical increases in life span at older ages are partly explained by reduced lifetime exposure to infection and subsequent inflammation. To begin a test of this hypothesis, we compare C-reactive protein (CRP); levels in two populations with different epidemiological environments: the Tsimane of Bolivia and persons in the United States. …
