Patterns Of Senescence In Human Cardiovascular Fitness: Vo2 Max In Subsistence And Industrialized Populations, Anne C. Pisor, Michael Gurven, Aaron D. Blackwell, Hillard Kaplan, Gandhi Yetish

ESI Publications

Objectives—This study explores whether cardiovascular fitness levels and senescent decline are similar in the Tsimane of Bolivia and Canadians, as well as other subsistence and industrialized populations. Among Tsimane, we examine whether morbidity predicts lower levels and faster decline of cardiovascular fitness, or whether their lifestyle (e.g., high physical activity) promotes high levels and slow decline. Alternatively, high activity levels and morbidity might counterbalance such that Tsimane fitness levels and decline are similar to those in industrialized populations.

Methods—Maximal oxygen uptake (VO2max) was estimated using a step test heart rate method for 701 participants. We compared these estimates …

Age-Independent Increases In Male Salivary Testosterone During Horticultural Activity Among Tsimane Forager-Farmers, Benjamin C. Trumble, Daniel K. Cummings, Kathleen A. O'Connor, Darryl J. Holman, Eric A. Smith, Hillard Kaplan, Michael D. Gurven

ESI Publications

Testosterone plays an important role in mediating male reproductive trade-offs in many vertebrate species, augmenting muscle and influencing behavior necessary for male-male competition and mating-effort. Among humans, testosterone may also play a key role in facilitating male provisioning of offspring as muscular and neuromuscular performance are deeply influenced by acute changes in testosterone. This study examines acute changes in salivary testosterone among 63 Tsimane men ranging in age from 16–80 (mean 38.2) years during one-hour bouts of treechopping while clearing horticultural plots. The Tsimane forager-horticulturalists living in the Bolivian Amazon experience high energy expenditure associated with food production, have high …

Project-Based Section 8 Housing Participants' Perception Of Cultural And Structural Factors To Explain Barriers To Economic Self-Sufficiency, Yolanda Javette Clark

Dissertations

The Project-Based Section 8 program began as temporary housing of the last resort for people who experience temporary setbacks. However, due to participants' inability to become economically self-sufficient, the anti-poverty program has become permanent housing from which few families have been able to escape. Recent studies related to escaping poverty and becoming economically self-sufficient suggest cultural and structural factors are equally important and collectively impact upward economic mobility.

Similarly, the purpose of this study was to determine if Project-Based Section 8 housing participants' characteristics, described as cultural and structural barriers to economic self-sufficiency, interrelate and collectively predict ability to escape …

Comparative Approaches To Studying Strategy: Towards An Evolutionary Account Of Primate Decision Making, Sarah F. Brosnan, Michael J. Beran, Audrey E. Parrish, Sara A. Price, Bart J. Wilson

Economics Faculty Articles and Research

How do primates, humans included, deal with novel problems that arise in interactions with other group members? Despite much research regarding how animals and humans solve social problems, few studies have utilized comparable procedures, outcomes, or measures across different species. Thus, it is difficult to piece together the evolution of decision making, including the roots from which human economic decision making emerged. Recently, a comparative body of decision making research has emerged, relying largely on the methodology of experimental economics in order to address these questions in a cross-species fashion. Experimental economics is an ideal method of inquiry for this …

The Remittance Intentions Of Second-Generation Ghanaian-Americans, Kirstie Kwarteng

Capstone Collection

Remittances have become an integral part of economies all over the Global South and Ghana is no exception. Official accounts estimate that remittances to Ghana have been as high as US $1 billion a year, although the true number is likely to be much higher as funds are also remitted through informal channels. This is a significant inflow of foreign currency, sent almost completely by first generation Ghanaian immigrants abroad. To maintain this level of inflows over the long run, however, would require that second-generation Ghanaian immigrants continue to remit at the same level as their parents. This study examines …

Dharma And The Free Market: Reconciling Buddhist Compassion With A Market Economy In Post-Socialist Mongolia, Yazmeen Mendez Nuñez

Independent Study Project (ISP) Collection

In this inductive ethnographic study, I explore the unique social and theological pressures placed on Mongolian Buddhists after the wake of free market transition in Mongolia. It utilizes the Buddhist virtue of compassion as a lens by which the study might examine how Mongolians balance their spirituality and commitment to Buddhist ethics with new roles as rational agents in an emergent free market. In this study I draw on narratives from thirteen subjects as well as extensive participant observation to examine the ways that Mongolian market reform has guided social paradigms of ethic that present ethical contradictions with Buddhist dharma, …

“Resistencia Es Permanencia”: Concepciones De Resistencia, Territorio Y Recuperaciones De Tierra En Dos Comunidades Mapuche, August Williams-Eynon

Independent Study Project (ISP) Collection

In recent decades the world has seen a backlash of resistance, especially among First Nations and indigenous populations, to what some characterize as new forms of colonization: the development of globalization, and the spread of neoliberal economic institutions and their guiding principles (Vanden 2007). This work locates the social movements of the Mapuche (an indigenous nation conquered by the Chilean army in 1883), and especially their pursuance of land recovery and territorial sovereignty, among the many such mobilizations occurring in Latin America, including the Zapatista movement in Mexico, the organizing of indigenous groups in Bolivia and the CONAIE (Confederación de …

Global Futures And Government Towns: Phosphates And The Production Of Western Sahara As A Space Of Contention, Mark Drury

Publications and Research

The study of natural resources lends itself to theorizing the politics of nature and the politics of time. The space of Western Sahara, where both remain highly contested, provides an opportunity to consider the ramifications of resources in political conflict at different historical moments. Drawing from environmental histories of North Africa and the Sahara, as well as the anthropology of time, the author focuses on two historical moments. The first, from 1945 to 1972, concerns the discovery of phosphate deposits during the Spanish colonial period and the implications of this discovery for political authority in the Sahara more broadly. The …

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 …

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 …

Women's Mobilization In Latin America: A Case Study Of Venezuela, Brianna Russell

Master's Theses

Abstract

I examine the following elements in regards to women’s mobilization in Latin America and Venezuela from the late 1950s to the present: (a) the influence of the state and economy on times when women mobilized (b) class division within the movement (c) women’s demands during different time periods (d) the ways in which women were successful in working towards gender equality. This thesis reviews the literature on women’s mobilization in Latin America during the second half of the twentieth century. I find that women mobilized across class lines with the masses to end dictatorships. Women demobilized during transitions to …

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 …

How Do Latino Groups Fare In A Changing Economy? Occupation In Latino Groups In The Greater New York City Area, 1980-2009, Stephen Ruszczyk

Center for Latin American, Caribbean, and Latino Studies

Introduction: This study examines demographic and socioeconomic factors of racial/ethnic groups in New York City between 1980 and 2009 – particularly the Latino population.

Methods: Data on Latinos and other racial/ethnic groups were obtained from the U.S. Census Bureau American Community Survey, reorganized for public use by the Minnesota Population Center, University of Minnesota, IPUMSusa. Cases in the dataset were weighted and analyzed to produce population estimates.

Results: Trends from 1990 continued in 2000, with numbers of Puerto Ricans in production dropping to only 14% of that group. More than a fifth of Puerto Ricans worked in management and professional …

Chogyal's Sikkim: Tax, Land & Clan Politics, Hong Tran

Independent Study Project (ISP) Collection

During the Chogyal (Tib. chos rgyal1) reign, the first and last monarchy in Sikkim, land and various forms of taxes derived from land ownership were powerful instruments of the ruling class, namely the Chogyal family, the aristocratic clans, and the royal lamas. It is the objective of this paper to examine the institution of land ownership and taxation as a reflection of the deeply seated and potent clan politics of Sikkim. Through available records and literature as well as interviews with head lamas, monastic affiliates and the Sikkimese public, using a combination of narratives and analysis, this author hopes to …

A Necessary Effort: The Construction Of A Binational Immigration Policy For Nicaraguan Immigrants In Costa Rica, Irma Castañeda

Independent Study Project (ISP) Collection

Although the experiences of Nicaraguan immigrants to Costa Rica have been well-studied, the investigation of this topic through the lens of the construction of public policies is missing. Through the testimonies of Nicaraguans that emigrated or still live and work in Costa Rica, I learned that immigrants, especially those that are undocumented, are vulnerable to the violation of their rights, for example, through the lack of access to public services or mistreatment by their bosses. Because of these violations, it is necessary to examine the topic of the immigration policies of both countries because they influence the treatment and integration …

Empresas Recuperadas, Elana Gold

Independent Study Project (ISP) Collection

Starting during the neoliberal economic policies of the 90’s and continuing through the crisis of 2001, over 200 abandoned or bankrupt factories have been recuperated by their workers to maintain their jobs and argentine industry. These factories, called empresas recuperadas, have an important role in providing economic alternatives to the typical exploitation of capitalism as nearly all are maintained as cooperatives where members share in the decision-making process and profits. Although they have their roots in the militant union history of Argentina, in many ways they have differentiated themselves from the typical worker struggle.

These factories have an interesting relationship …

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 …

Political Globalization And Civil War In Former British Colonies, Luke O. Feltz

Student Publications

The purpose of this paper to determine why civil war onset reduces political globalization in former British colonies. I set out by testing the relationship between being a former British colony and civil war presence, demonstrating a positive, though not statistically significant, relationship. I also examine the history of British colonialism. Through setting up specific system of indirect rule, British colonizers created conditions that contributed to intra-state conflict. Furthermore, through constructing a unique institutional system and maintaining ties to its former colonies, the British have created an atmosphere conducive to international political engagement after the onset of civil war. Yet, …

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 …

Social Norms, Discrete Choices, And False Dichotomies, Eric Schniter, Nathaniel Wilcox

Psychology Faculty Articles and Research

Eric Schniter and Nathaniel Wilcox comment on Bram Tucker's article, "Do Risk and Time Experimental Choices Represent Individual Strategies for Coping with Poverty or Conformity to Social Norms? Evidence from Rural Southwestern Madagascar", which "revisits a debate played out in Current Anthropology as to whether subsistence decisions are the result of individual strategy to cope with poverty and increase wealth... or conformity to social norms."

Constructing Cidadania: Shifting Visions Of Citizenship In The Mst Settlement Assentamento 25 De Maio In Ceará, Brazil, Alexis Victoria Cruzzavala

Independent Study Project (ISP) Collection

The social movement known as Movimento dos Trabalhadores Rurais Sem Terra (MST) was founded in 1984 with the intent of agrarian reform in a newly democratic Brazil. The movement arrived in Northeastern Brazil in the late 1980s and successfully organized a group of landless workers in the interior of Ceará on May 25, 1989 to create the first settlement the state had seen. The citizens of Assentamento 25 de Maio, as the settlement was later named, have undergone a unique social transition from circumstances closely resembling forced servitude and latifúndio to liberation. This transition affected the men and women who …

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 …

Renegotiating Gender And Class In The Berry Fields Of Michoacán, Mexico, Donna Chollett

Anthropology Publications

This article examines the renegotiation of gender and class in a rural Mexican community where economic crisis in the sugar industry led foreign agribusinesses to promote blackberry and raspberry production for export and hire primarily women as berry pickers. Analysis focuses on the transition from a sugar economy where mostly men worked in the cane fields to non-traditional agricultural exports when women entered agricultural waged labor in unprecedented numbers. This restructuring of the regional economy raises important questions regarding the marginalization of differentiated subaltern groups and the nature of new sets of power relations between transnational agribusinesses, berry growers, and …
