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 …

Strategies For The Scientific Progress Of The Developing Countries In The New Millennium: The Case Of Serbia In Comparison With Slovenia And South Korea, Vuk Uskoković, Milica Ševkušić, Dragan P. Uskoković

Pharmacy Faculty Articles and Research

The underlying premise of this essay is the hypothesis that quality and significance of scientific research in any given society could be used as mirrors reflecting its true prosperity. By comparing the two cases of comparatively prosperous scientific management of South Korea and Slovenia, with the example of Serbia, illustrating the poor scientific and industrial productivity typically faced by the developing countries, a few general guidelines for the evolution of a society towards higher scientific and social prominence are outlined. It is argued that the most favourable pattern of growth should be based on the parallel progress in control of …

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. …

Jean-Baptiste Debret’S Return Of The Negro Hunters, The Brazilian Roça, And The Interstices Of Empire, Amy J. Buono

Art Faculty Books and Book Chapters

"Despite the range of subjects that Debret illustrates, historians of Brazil have usually only reproduced his images of Afro-Brazilian slaves. This is understandable, given the political, social and economic interest in the topic and the fact that Debret is one of the few artists who portrayed the horrors of slavery in Brazil at so early date.³ The keen interest in slavery as an historical topic has also led some scholars to assume that all Afro-Brazilians depicted in Debret's volumes are slaves, when many individuals may in fact have been free.⁴ While acknowledging the importance of examining Debret's images …

Time To Make History, Time To Educate Women: A Narrative Of The Life And Work Of Christiana Thorpe Of Sierra Leone, Whitney Mcintyre Miller

Education Faculty Articles and Research

An examination of the life of Christiana Thorpe, a former nun from Sierra Leone who worked to improve education for girls and served as the only woman in a cabinet of nineteen members (as Minister of Education), then worked with the United Nations Development Programme and UNESCO amidst war and rebellion in her country.

The Evolution Of Human Life Expectancy And Intelligence In Hunter-Gatherer Economies, Hillard Kaplan

ESI Publications

The economics of hunting and gathering must have driven the biological evolution of human characteristics, since hunter-gatherer societies prevailed for the two million years of human history. These societies feature huge intergenerational resource flows, suggesting that these resource flows should replace fertility as the key demographic consideration. It is then theoretically expected that life expectancy and brain size would increase simultaneously, as apparently occurred during our evolutionary history. The brain here is considered as a direct form of bodily investment, but also crucially as facilitating further indirect investment by means of learning-by-doing.
