Smoking Trends Among U.S. Latinos, 1998–2013: The Impact Of Immigrant Arrival Cohort, Georgiana Bostean, Annie Ro, Nancy L. Fleischer

Sociology Faculty Articles and Research

Few studies examine nativity disparities in smoking in the U.S., thus a major gap remains in understanding whether immigrant Latinos’ smoking prevalence is stable, converging, or diverging, compared with U.S.-born Latinos. This study aimed to disentangle the roles of period changes, duration of U.S. residence, and immigrant arrival cohort in explaining the gap in smoking prevalence between foreign-born and U.S.-born Latinos. Using repeated cross-sectional data spanning 1998–2013 (U.S. National Health Interview Survey), regressions predicted current smoking among foreign-born and U.S.-born Latino men and women (n = 12,492). We contrasted findings from conventional regression analyses that simply include period and duration …

Predictors Of Hepatitis C Testing Intention Among African American Baby Boomers, Mohamed Rashrash, Mary Maneno, Anthony Wutoh, Earl Ettienne, Monica Daftary

Pharmacy Faculty Articles and Research

Baby Boomers (BBs) are responsible for three-quarters of hepatitis C virus (HCV) infections in the United States; however, HCV testing is distinctly underused by them. A cross-sectional study was conducted to assess the prevalence of HCV testing and to evaluate predictors of HCV testing intention among African– American BBs. The study was guided by the Health Belief Model and theory of reasoned action frameworks. Of the 137 participants included in the study, 44.8% had at least a college education; 13.9% received prior to 1992 blood transfusion. Findings related to HCV testing showed that 32.1% of the participants intended to test …

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 …

Smoking Selectivity Among Mexican Immigrants To The United States Using Binational Data, 1999–2012, Nancy L. Fleischer, Annie Ro, Georgiana Bostean

Sociology Faculty Articles and Research

Mexican immigrants have lower smoking rates than US-born Mexicans, which some scholars attribute to health selection—that individuals who migrate are healthier and have better health behaviors than their non-migrant counterparts. Few studies have examined smoking selectivity using binational data and none have assessed whether selectivity remains constant over time. This study combined binational data from the US and Mexico to examine: 1) the extent to which recent Mexican immigrants (< 10 years) in the US are selected with regard to cigarette smoking compared to non-migrants in Mexico, and 2) whether smoking selectivity varied between 2000 and 2012—a period of declining tobacco use in Mexico and the US. We combined repeated cross-sectional US data (n = 10.901) on adult (ages 20–64) Mexican immigrants and US-born Mexicans from the 1999/2000 and 2011/2012 National Health Interview Survey, and repeated cross-sectional Mexican data on non-migrants (n …

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 …

African American Culture In Historical Art Museums: Remembering A Buried Tragic Past, Lana Sarkisian

Student Scholar Symposium Abstracts and Posters

The transparency of reality reflecting in art often represents a false tragedy in African American history because of the lack of preservation and representation due to a predominantly white dominion, ultimately leaving the veracity of their history to consign to oblivion. There is a common thread of forgetfulness with the retrieval of art in today’s society that embodies the African American community. Although artist Fred Wilson does not explicitly assert his assessment to the lack of black representation on account of cultural differences, he vocalizes how African American culture is indoctrinated to the public in a white, supremacist national narrative …

Growth References For Tsimane Forager-Horticulturalists Of The Bolivian Amazon, Aaron D. Blackwell, Samuel S. Urlacher, Bret Beheim, Christopher Von Rueden, Adrian V. Jaeggi, Jonathan Stieglitz, Benjamin C. Trumble, Michael Gurven, Hillard Kaplan

ESI Publications

Objectives—Growth standards and references currently used to assess population and individual health are derived primarily from urban populations, including few individuals from indigenous or subsistence groups. Given environmental and genetic differences, growth may vary in these populations. Thus, there is a need to assess whether international standards are appropriate for all populations, and to produce population specific references if growth differs. Here we present and assess growth references for the Tsimane, an indigenous population of Bolivian forager-horticulturalists.

Methods—Mixed cross-sectional/longitudinal anthropometrics (9,614 individuals; 30,118 observations; ages 0–29 years) were used to generate centile curves and Lambda-Mu-Sigma (LMS) tables for …

Salivary Microbiomes Of Indigenous Tsimane Mothers And Infants Are Distinct Despite Frequent Premastication, Cliff S. Han, Melanie Ann Martin, Armand E.K. Dichosa, Ashlynn R. Daughton, Seth Frietze, Hillard Kaplan, Michael D. Gurven, Joe Alcock

ESI Publications

Background. Premastication, the transfer of pre-chewed food, is a common infant and young child feeding practice among the Tsimane, forager-horticulturalists living in the Bolivian Amazon. Research conducted primarily with Western populations has shown that infants harbor distinct oral microbiota from their mothers. Premastication, which is less common in these populations, may influence the colonization and maturation of infant oral microbiota, including via transmission of oral pathogens. We collected premasticated food and saliva samples from Tsimane mothers and infants (9-24 months of age) to test for evidence of bacterial transmission in premasticated foods and overlap in maternal and infant salivary …

Women And Revolution: Marx And The Dialectic, Lilia D. Monzó

Education Faculty Articles and Research

This article argues that Marxism is inherently anti-sexist, anti-racist, and against all forms of exploitation and oppression. As a philosophy of revolution, Marxism is more than about economic restructuring but rather argues for the development of a new humanity based upon a class-less mode of production. Dialectically, these changes must come simultaneously from changing relations of production, changes in the material conditions of families, and the development of values and ideologies related to freedom and equality. Women's liberation and anti-racism play a central role in this revolution. Working class women and women of color are especially roused to action due …

18th And 19th Century European Philosophy And The Justification Of Colonial And Economic Exploits, Danielle Platt, Ian Nell

Honors Papers and Posters

The theories and philosophies that have evolved over the course of human history have each influenced and affected the politics and the behaviors of the societies where they are popularized. We wish to study the sorts of relationships that may exist between popular European philosophies of the 18th and 19th centuries, and the political ideologies of the time, and why they still bear relevance in global politics today’s globalized international community.

Cardiovascular Disease And Type 2 Diabetes In Evolutionary Perspective: A Critical Role For Helminths?, Michael D. Gurven, Benjamin C. Trumble, Jonathan Stieglitz, Aaron D. Blackwell, David E. Michalik, Caleb E. Finch, Hillard Kaplan

ESI Publications

Heart disease and type 2 diabetes are commonly believed to be rare among contemporary subsistencelevel human populations, and by extension prehistoric populations. Although some caveats remain, evidence shows these diseases to be unusual among well-studied hunter-gatherers and other subsistence populations with minimal access to healthcare. Here we expand on a relatively new proposal for why these and other populations may not show major signs of these diseases. Chronic infections, especially helminths, may offer protection against heart disease and diabetes through direct and indirect pathways. As part of a strategy to insure their own survival and reproduction, helminths exert multiple cardio-protective …

Architecture Of Diversity: Using The Lens And Language Of Space To Examine Racialized Experiences Of Students Of Color On College Campuses, Michelle Samura

Education Faculty Books and Book Chapters

"[A]n examination of racial diversity in higher education requires serious consideration of space... [A] spatial perspective offers a lens for locating and examining processes of racialization. And a spatial approach also provides a language participants and researchers can use to talk about the discreet ways race still operates in everyday interactions, including subtle forms of racism that are overlooked or ignored because race is often understood by students to matter less today. Essentially, a spatial approach sheds light on race relations and racial structures in tangible campus environments."

An Epigenetic Clock Analysis Of Race/Ethnicity, Sex, And Coronary Heart Disease, Steve Horvath, Michael Gurven, Morgan E. Levine, Benjamin C. Trumble, Hillard Kaplan, Hooman Allayee, Beate R. Ritz, Brian Chen, Ake T. Lu, Tammy M. Rickabaugh, Beth D. Jamieson, Dianjianyi Sun, Shengxu Li, Wei Chen, Lluis Quintana-Murci, Maud Fagny, Michael S. Kobor, Philip S. Tsao, Alexander P. Reiner, Kerstin L. Edlefsen, Devin Absher, Themistocles L. Assimes

ESI Publications

Background: Epigenetic biomarkers of aging (the “epigenetic clock”) have the potential to address puzzling findings surrounding mortality rates and incidence of cardio-metabolic disease such as: (1) women consistently exhibiting lower mortality than men despite having higher levels of morbidity; (2) racial/ethnic groups having different mortality rates even after adjusting for socioeconomic differences; (3) the black/white mortality cross-over effect in late adulthood; and (4) Hispanics in the United States having a longer life expectancy than Caucasians despite having a higher burden of traditional cardio-metabolic risk factors.

Results: We analyzed blood, saliva, and brain samples from seven different racial/ethnic groups. …

Associations Between Male Testosterone And Immune Function In A Pathogenically Stressed Forager-Horticultural Population, Benjamin C. Trumble, Aaron D. Blackwell, Jonathan Stieglitz, Melissa Emery Thompson, Ivan Maldonado Suarez, Hillard Kaplan, Michael Gurven

ESI Publications

Objectives—Despite well-known fitness advantages to males who produce and maintain high endogenous testosterone levels, such phenotypes may be costly if testosterone-mediated investment in reproductive effort trade-off against investment in somatic maintenance. Previous studies of androgen-mediated trade-offs in human immune function find mixed results, in part because most studies either focus on a few indicators of immunity, are confounded by phenotypic correlation, or are observational. Here the association between male endogenous testosterone and 13 circulating cytokines are examined before and after ex vivo antigen stimulation with phytohaemagglutinin (PHA) and lipopolysaccharides (LPS) in a high pathogen population of Bolivian forager-horticulturalists.

Health Costs Of Reproduction Are Minimal Despite High Fertility, Mortality And Subsistence Lifestyle, Michael Gurven, Megan Costa, Ben Trumble, Jonathan Stieglitz, Bret Beheim, Daniel Eid Rodriguez, Paul L. Hooper, Hillard Kaplan

ESI Publications

Women exhibit greater morbidity than men despite higher life expectancy. An evolutionary life history framework predicts that energy invested in reproduction trades-off against investments in maintenance and survival. Direct costs of reproduction may therefore contribute to higher morbidity, especially for women given their greater direct energetic contributions to reproduction. We explore multiple indicators of somatic condition among Tsimane forager-horticulturalist women (Total Fertility Rate = 9.1; n = 592 aged 15–44 years, n = 277 aged 45+). We test whether cumulative live births and the pace of reproduction are associated with nutritional status and immune function using longitudinal data spanning 10 …

High Resting Metabolic Rate Among Amazonian Forager-Horticulturalists Experiencing High Pathogen Burden, Michael Gurven, Benjamin C. Trumble, Jonathan Stieglitz, Gandhi Yetish, Daniel Cummings, Aaron D. Blackwell, Bret Beheim, Hillard Kaplan, Herman Pontzer

ESI Publications

Objectives—Resting metabolic rate (RMR) reflects energetic costs of homeostasis and accounts for 60-75% of total energy expenditure (TEE). Lean mass and physical activity account for much RMR variability, but the impact of prolonged immune activation from infection on human RMR is unclear in naturalistic settings. We evaluate the effects of infection on mass-corrected RMR among Bolivian forager-horticulturalists, and assess whether RMR declines more slowly with age than in hygienic sedentary populations, as might be expected if older adults experience high pathogen burden.

Materials and Methods—RMR was measured by indirect calorimetry (Fitmate MED, Cosmed) in 1,300 adults aged 20-90 …

Immune Function In Amazonian Horticulturalists, Aaron D. Blackwell, Benjamin C. Trumble, Ivan Maldonado Suarez, Jonathan Stieglitz, Bret Beheim, J. Josh Snodgrass, Hillard Kaplan, Michael Gurven

ESI Publications

Background—Amazonian populations are exposed to diverse parasites and pathogens, including protozoal, bacterial, fungal, and helminthic infections. Yet much of our understanding of the immune system is based on industrialised populations where these infections are relatively rare.

Aim—We examine distributions and age-related differences in 22 measures of immune function for Bolivian forager-horticulturalists and US and European populations.

Subjects and Methods—Subjects were 6,338 Tsimane aged 0–90 years. Blood samples collected between 2004–2014 were analysed for 5-part blood differentials, C-reactive protein, erythrocyte sedimentation rate (ESR), and total immunoglobulins E, G, A, and M. Flow cytometry was used to quantify naive …

Young, Urban, Professional, And Kenyan?: Conversations Surrounding Tribal Identity And Nationhood, Charlotte Achieng-Evensen

Educational Studies Dissertations

By asking the question “How do young, urban, professional Kenyans make connections between tribal identity, colonialism, and the lived experience of nationhood?,” the researcher engages with eight participants in exploring their relationships with their tribal groups. From this juncture the researcher, through a co-constructed process with participants, interrogates the idea of nationhood by querying their interpretations of the concepts of power and resistance within their multi-ethnic societies. The utility of KuPiga Hadithi as a cultural responsive methodology for data collection along with poetic analysis as part of the qualitative tools of examination allowed the researcher to identify five emergent and …

Remaking Selves, Repositioning Selves, Or Remaking Space: An Examination Of Asian American College Students' Processes Of "Belonging", Michelle Samura

Education Faculty Articles and Research

"Only a few studies have examined Asian American students’ sense of belonging (Hsia, 1988; Lee & Davis, 2000; Museus & Maramba, 2010). Scholars who study Asian American college students have suggested that Asian Americans are awkwardly positioned as separate from other students of color vis-à-vis the model minority stereotype (Hsia, 1988; Lee & Davis, 2000). Furthermore, Asian Americans often are viewed as overrepresented on college campuses, yet they remain under-served by campus support programs and resources and overlooked by researchers. Many Asian Americans have gained access to higher education, but the ways in which they belong on campuses is unclear. …

"Their Shadows Still Walk With Us": Mapping A Decolonial Cartography Of Struggle With Ingrid Washinawatok El-Issa, Sandra Álvarez

‘Tell Your Own Story’: Manhood, Masculinity And Racial Socialization Among Black Fathers And Their Sons, Quaylan Allen

Education Faculty Articles and Research

This study examines how black fathers and sons in the U.S. conceptualize manhood and masculinity and the racial socializing practices of black men. Drawing upon data from an ethnography on Black male schooling, this paper uses the interviews with fathers and sons to explore how race and gender intersect in how Black males make meaning of their gendered performances. Common notions of manhood are articulated including independence, responsibility and providership. However, race and gender intersect in particular ways for black men. The fathers engaged in particular racial socializing practices preparing their sons for encounters with racism. Both fathers and sons …

Helminth Infection, Fecundity, And Age Of First Pregnancy In Women, Aaron D. Blackwell, Marilyne D. Tamayo, Bret Beheim, Benjamin C. Trumble, Jonathan Stieglitz, Paul L. Hooper, Melanie Martin, Hillard Kaplan, Michael Gurven

ESI Publications

Infection with intestinal helminths results in immunological changes that influence the odds of comorbid infections, and might also affect fecundity by inducing immunological states supportive of conception and pregnancy. Here we investigate associations between intestinal helminths and fertility in human females, utilizing nine years of longitudinal data from 986 Bolivian forger-horticulturalists, experiencing natural fertility and a 70% helminth prevalence. We find that different species of helminth are associated with opposing effects on fecundity. Infection with roundworm (Ascaris lumbricoides) is associated with earlier first births and shortened interbirth intervals, while infection with hookworm is associated with delayed first pregnancy and extended …

Natural Sleep And Its Seasonal Variations In Three Pre-Industrial Societies, Gandhi Yetish, Hillard Kaplan, Michael Gurven, Brian Wood, Herman Pontzer, Paul R. Manger, Charles Wilson, Ronald Mcgregor, Jerome M. Siegel

ESI Publications

How did humans sleep before the modern era? Because the tools to measure sleep under natural conditions were developed long after the invention of the electric devices suspected of delaying and reducing sleep, we investigated sleep in three preindustrial societies[1–3]. We find that all three show similar sleep organization, suggesting that they express core human sleep patterns, likely characteristic of pre-modern era Homo sapiens. Sleep periods, the times from onset to offset, averaged 6.9–8.5-h, with sleep durations of 5.7–7.1-h, amounts near the low end of those industrial societies[4–7]. There was a difference of nearly 1-h between summer and winter sleep. …

“There’S Still That Window That’S Open”: The Problem With “Grit”, Noah Asher Golden

Education Faculty Articles and Research

This narrative analysis case study challenges the education reform movement’s fascination with “grit,” the notion that a non-cognitive trait like persistence is at the core of disparate educational outcomes and the answer to our inequitable education system. Through analysis of the narratives and meaning-making processes of Elijah, a 20-year-old African American seeking his High School Equivalency diploma, this case study explores linkages among dominant discourses on meritocracy, opportunity, personal responsibility, and group blame. Specifically, exposition of the figured worlds present in Elijah’s narratives points to the attempted obfuscation of social inequities present in the current educational reform movement and our …

Calcaneal Quantitative Ultrasound Indicates Reduced Bone Status Among Physically Active Adult Forager-Horticulturalists, Jonathan Stieglitz, Felicia C. Madimenos, Hillard Kaplan, Michael Gurven

ESI Publications

Six months of exclusive breastfeeding (EBF) is considered optimal for infant health, though globally most infants begin complementary feeding (CF) earlier—including among populations that practice prolonged breastfeeding. Two frameworks for understanding patterns of early CF emerge in the literature. In the first, maternal and infant needs trade-off, as “maternal-centric” factors—related to time and energy demands, reproductive investment, cultural influences, and structural barriers— favor supplanting breastfeeding with earlier and increased CF. A second framework considers that “infant-centric” factors—related to infant energetic needs—favor CF before six months to supplement breastfeeding.

We apply these two frameworks in examining early CF among the Tsimane—a …

Does Market Integration Buffer Risk, Erode Traditional Sharing Practices And Increase Inequality? A Test Among Bolivian Forager-Farmers, Michael Gurven, Adrian V. Jaeggi, Christopher Von Rueden, Paul L. Hooper, Hillard Kaplan

ESI Publications

Sharing and exchange are common practices for minimizing food insecurity in rural populations. The advent of markets and monetization in egalitarian indigenous populations presents an alternative means of managing risk, with the potential impact of eroding traditional networks. We test whether market involvement buffers several types of risk and reduces traditional sharing behavior among Tsimane Amerindians of the Bolivian Amazon. Results vary based on type of market integration and scale of analysis (household vs. village), consistent with the notion that local culture and ecology shape risk management strategies. Greater wealth and income were unassociated with the reliance on others for …

Depression As Sickness Behavior? A Test Of The Host Defense Hypothesis In A High Pathogen Population, Jonathan Stieglitz, Benjamin C. Trumble, Melissa Emery Thompson, Aaron D. Blackwell, Hillard Kaplan, Michael Gurven

ESI Publications

Sadness is an emotion universally recognized across cultures, suggesting it plays an important functional role in regulating human behavior. Numerous adaptive explanations of persistent sadness interfering with daily functioning (hereafter “depression”) have been proposed, but most do not explain frequent bidirectional associations between depression and greater immune activation. Here we test several predictions of the host defense hypothesis, which posits that depression is part of a broader coordinated evolved response to infection or tissue injury (i.e. “sickness behavior”) that promotes energy conservation and reallocation to facilitate immune activation. In a high pathogen population of lean and relatively egalitarian Bolivian foragerhorticulturalists, …
