Mybarrio: Emigdio Vasquez And Chicana/O Identity In Orange County, Natalie Lawler, Denise Johnson, Marcus Herse, Jessica Bocinski, Manon Wogahn

Exhibition Catalogs

"Emigdio Vasquez created artwork that challenged Orange County’s more prominent narrative of wealthy beachside neighborhoods. He painted the brown bodies and brown histories that defined our earliest communities and economy... Vasquez produced much of the local art history that Orange County should be known for and should protect. It is with this perspective that Chapman University is proud to present the exhibition, My Barrio: Emigdio Vasquez and Chicana/o Identity in Orange County, in conjunction with the Getty Pacific Standard Time: LA/LA initiative. We hope to initiate discourse not only about Vasquez’s prolific career, but also about the larger political …

“They Write Me Off And Don't Give Me A Chance To Learn Anything”: Positioning, Discipline, And Black Masculinities In School, Quaylan Allen

Education Faculty Articles and Research

This study examines the schooling of black male students in a U.S. high school. Drawing upon positioning theory and student resistance literature, I describe how the students make meaning of the pathologizing positioning practices of the school, including how they resist and internalize dominant discourses about black masculinity and how their performances of particular masculinities within the school are met with surveillance, regulation, and discipline. I argue that schools are locations where dominant ideologies of black masculinities are imposed, contested, and sometimes reproduced.

My Crown And Glory: Community, Identity, Culture, And Black Women’S Concerns Of Hair Product-Related Breast Cancer Risk, Dede K. Teteh, Susanne B. Montgomery, Sabine Monice, Laura Stiel, Phyllis Y. Clark, Eudora Mitchell

Health Sciences and Kinesiology Faculty Articles

Breast cancer (BC) incidence rates for Black and non-Hispanic White women have recently converged; however, Black women continue to die at higher rates from the disease. Black women also use hair products containing hormonally active chemicals at higher rates than other races and ethnic groups. Studies now link chemical components in hair and personal care products to breast cancer risk. Using a community-based participatory research approach, this qualitative study explored community concerns about the role of hair products on breast cancer risk. Focus groups and key informant interviews using triangulation to assure relevant perspectives (women with and without breast cancer …

“That’S Why I Say Stay In School”: Black Mothers’ Parental Involvement, Cultural Wealth, And Exclusion In Their Son’S Schooling, Quaylan Allen, Kimberly A. White-Smith

Education Faculty Articles and Research

This study examines parental involvement practices, the cultural wealth, and school experiences of poor and working-class mothers of Black boys. Drawing upon data from an ethnographic study, we examine qualitative interviews with four Black mothers. Using critical race theory and cultural wealth frameworks, we explore the mothers’ approaches to supporting their sons’ education. We also describe how the mothers and their sons experienced exclusion from the school, and how this exclusion limited the mothers’ involvement. We highlight their agency in making use of particular forms of cultural wealth in responding to the school’s failure of their sons.

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 …

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 …

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 …
