Poverty Mapping Using Convolutional Neural Networks Trained On High And Medium Resolution Satellite Images, With An Application In Mexico, Boris Babenko, Jonathan Hersh, David Newhouse, Anusha Ramakrishnan, Tom Swartz

Economics Faculty Articles and Research

Mapping the spatial distribution of poverty in developing countries remains an important and costly challenge. These “poverty maps” are key inputs for poverty targeting, public goods provision, political accountability, and impact evaluation, that are all the more important given the geographic dispersion of the remaining bottom billion severely poor individuals. In this paper we train Convolutional Neural Networks (CNNs) to estimate poverty directly from high and medium resolution satellite images. We use both Planet and Digital Globe imagery with spatial resolutions of 3-5 m2 and 50 cm2 respectively, covering all 2 million km2 of Mexico. Benchmark poverty estimates come from …

Mybarrio: Emigdio Vasquez And Chicana/O Identity In Orange County, Natalie Lawler, Denise Johnson, Marcus Herse, Jessica Bocinski, Manon Wogahn Sep 2017

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 …

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 Apr 2017

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 Mar 2017

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 …


From Liberation To Salvation: Revolutionary Critical Pedagogy Meets Liberation Theology, Peter Mclaren, Petar Jandrić Mar 2017

From Liberation To Salvation: Revolutionary Critical Pedagogy Meets Liberation Theology, Peter Mclaren, Petar Jandrić

Education Faculty Articles and Research

This conversation between Peter McLaren and Petar Jandric´ brings about some of the most recent and deepest of McLaren’s insights into the relationship between revolutionary critical pedagogy and liberation theology, and outlines the main directions of development of McLaren’s thought during and after Pedagogy of Insurrection. In the conversation, McLaren reveals his personal and theoretical path to liberation theology. He argues for the relevance of liberation theology for contemporary social struggles, links it with social sciences, and addresses some recent critiques of Pedagogy of Insurrection. McLaren identifies the idolatry of money as the central point of convergence between liberation …


Smoking Trends Among U.S. Latinos, 1998–2013: The Impact Of Immigrant Arrival Cohort, Georgiana Bostean, Annie Ro, Nancy L. Fleischer Mar 2017

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 …


Rulers, Religion, And Riches: Why The West Got Rich And The Middle East Did Not, Jared Rubin Mar 2017

Rulers, Religion, And Riches: Why The West Got Rich And The Middle East Did Not, Jared Rubin

Economics Faculty Books and Book Chapters

For centuries following the spread of Islam, the Middle East was far ahead of Europe. Yet, the modern economy was born in Europe. Why was it not born in the Middle East? In this book Jared Rubin examines the role that Islam played in this reversal of fortunes. It argues that the religion itself is not to blame; the importance of religious legitimacy in Middle Eastern politics was the primary culprit. Muslim religious authorities were given an important seat at the political bargaining table, which they used to block important advancements such as the printing press and lending at interest. …


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 Feb 2017

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 …


Chinese Communication Studies: Three Paths Converging, Wenshan Jia Jan 2017

Chinese Communication Studies: Three Paths Converging, Wenshan Jia

Communication Faculty Articles and Research

This contribution presents the possibilities for anthropological and neo-Marxist media within the hugely expanding sector of Chinese communication studies. China has sourced mostly from the American positivist tradition but is increasingly ­taking on board European critical thinking but it also needs to absorb some of the depth and diversity of indigenous scholarship existing in Chinese.

Jia, Lu, and Heisey (2002) presented an influential meta-analysis of every ­example of communication studies in China at that time. The book chapter which talks about the rise of the discipline and scholarship of Chinese communication as an academic discipline (Jia et al., 2014) summarises …


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 Jan 2017

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 …
