Trabecular Evidence For A Human-Like Gait In Australopithecus Africanus, Meir M. Barak, Daniel E. Lieberman, David Raichlen, Herman Pontzer, Anna G. Warrener, Jean-Jacques Hublin

Publications and Research

Although the earliest known hominins were apparently upright bipeds, there has been mixed evidence whether particular species of hominins including those in the genus Australopithecus walked with relatively extended hips, knees and ankles like modern humans, or with more flexed lower limb joints like apes when bipedal. Here we demonstrate in chimpanzees and humans a highly predictable and sensitive relationship between the orientation of the ankle joint during loading and the principal orientation of trabecular bone struts in the distal tibia that function to withstand compressive forces within the joint. Analyses of the orientation of these struts using microCT scans …

Trends In Poverty Rates Among Latinos In New York City And The United States, 1990 - 2011, Justine Calcagno

Introduction: This study examines demographic and socioeconomic factors regarding Latinos in New York City and the United States between 1990 and 2011 – particularly poverty rates.

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: The analyzed data indicate that the poverty rate among the national population over the last two decades increased. However, there were nuanced and complex trends within both New York City …

A New Look At The Dynamic Similarity Hypothesis: The Importance Of Swing Phase, David A. Raichlen, Herman Pontzer, Liza J. Shapiro

Publications and Research

Summary The Dynamic Similarity Hypothesis (DSH) suggests that when animals of different size walk at similar Froude numbers (equal ratios of inertial and gravitational forces) they will use similar size-corrected gaits. This application of similarity theory to animal biomechanics has contributed to fundamental insights in the mechanics and evolution of a diverse set of locomotor systems. However, despite its popularity, many mammals fail to walk with dynamically similar stride lengths, a key element of gait that determines spontaneous speed and energy costs. Here, we show that the applicability of the DSH is dependent on the inertial forces examined. In general, …

A Qualitative Study Of Community Home-Based Care And Antiretroviral Adherence In Swaziland, Robin Root, Alan Whiteside

Publications and Research

Introduction Antiretroviral therapy (ART) has rendered HIV and AIDS a chronic condition for individuals in many parts of the world. Adherence, however, is integral to achieving chronicity. Studies have shown both relatively high ART adherence rates in sub-Saharan Africa and the importance of community home-based care (CHBC) to facilitating this process. In light of diminished HIV and AIDS funding globally and increased reliance on CHBC throughout Africa, a better understanding of how CHBC may strengthen ART adherence is essential to improving patients’ quality of life, tending to the needs of care supporters and achieving healthier populations. Methods This article reports …

Dosage Considerations For Transcranial Direct Current Stimulation In Children: A Computational Modeling Study, Sudha Kilaru Kessler, Preet Minhas, Adam J. Woods, Alyssa Rosen, Casey Gorman, Marom Bikson

Publications and Research

Transcranial direct current stimulation (tDCS) is being widely investigated in adults as a therapeutic modality for brain disorders involving abnormal cortical excitability or disordered network activity. Interest is also growing in studying tDCS in children. Limited empirical studies in children suggest that tDCS is well tolerated and may have a similar safety profile as in adults. However, in electrotherapy as in pharmacotherapy, dose selection in children requires special attention, and simple extrapolation from adult studies may be inadequate. Critical aspects of dose adjustment include 1) differences in neurophysiology and disease, and 2) variation in brain electric fields for a specified …

Fashion Vs. Function In Cultural Evolution: The Case Of Dog Breed Popularity, Stefano Ghirlanda, Alberto Acerbi, Harold Herzog, James A. Serpell

Publications and Research

We investigate the relationship between characteristics of dog breeds and their popularity between years 1926 and 2005. We consider breed health, longevity, and behavioral qualities such as aggressiveness, trainability, and fearfulness. We show that a breed's overall popularity, fluctuations in popularity, and rates of increase and decrease around popularity peaks show typically no correlation with these breed characteristics. One exception is the finding that more popular breeds tend to suffer from more inherited disorders. Our results support the hypothesis that dog breed popularity has been primarily determined by fashion rather than function.

30 Days In The Life: Daily Nutrient Balancing In A Wild Chacma Baboon, Caley A. Johnson, David Raubenheimer, Jessica M. Rothman, David Clarke, Larissa Swedell

Publications and Research

For most animals, the ability to regulate intake of specific nutrients is vital to fitness. Recent studies have demonstrated nutrient regulation in nonhuman primates over periods of one observation day, though studies of humans indicate that such regulation extends to longer time frames. Little is known about longer-term regulation in nonhuman primates, however, due to the challenges of multiple-day focal follows. Here we present the first detailed study of nutrient intake across multiple days in a wild nonhuman primate. We conducted 30 consecutive all day follows on one female chacma baboon (Papio hamadryas ursinus) in the Cape Peninsula of South …

Evolution And Allometry Of Calcaneal Elongation In Living And Extinct Primates, Doug M. Boyer, Erik R. Seiffert, Justin T. Gladman, Jonathan I. Bloch

Publications and Research

Specialized acrobatic leaping has been recognized as a key adaptive trait tied to the origin and subsequent radiation of euprimates based on its observed frequency in extant primates and inferred frequency in extinct early euprimates. Hypothesized skeletal correlates include elongated tarsal elements, which would be expected to aid leaping by allowing for increased rates and durations of propulsive acceleration at takeoff. Alternatively, authors of a recent study argued that pronounced distal calcaneal elongation of euprimates (compared to other mammalian taxa) was related primarily to specialized pedal grasping. Testing for correlations between calcaneal elongation and leaping versus grasping is complicated by …

The Intellectual And Curricular Spaces Of Knowledge Studies, Jay H. Bernstein

Publications and Research

The words “knowledge” and “information” are sometimes used interchangeably, but the connection between them is complex and problematic. Knowledge is a mental product gained from engaging with information. All educational subjects, scholarly disciplines, occupations, and activities produce knowledge as well as information. Because libraries encompass potentially all subjects, professional vision in librarianship would benefit from an examination of knowledge that transcends the methods and topical concerns of individual disciplines. An interdisciplinary (or transdisciplinary) framework in which to view knowledge was pioneered in the post-Sputnik age by Fritz Machlup and Michael Polanyi. Their insights have stimulated scholars to develop research, publications, …

The Era Of Open-Ended Dual Life, Hirosuke Hyodo

Publications and Research

Although missing in mainstream studies of American immigration in the post-1965 Act era, the volume of native Japanese living in the U.S. today (called the shin-issei) is three times that of the prewar Japanese-American community on the U.S. mainland. Their curious absence from the mainstream studies results from the traditionally entrenched frame, ‘immigrants’, that does not unfit their migrant patterns. This paper explores the shin-issei, portraying their characters in three parts: (1) akogare (‘longing or desire’) for the West grown in Japan in the late nineteenth century, (2) a statistical sketch of the shin-issei over the last several decades, and …

Seroprevalence Of Epstein-Barr Virus Infection In U.S. Children Ages 6-19, 2003-2010, Jennifer Beam Dowd, Tia Palermo, Jennifer Brite, Thomas W. Mcdade, Allison Aiello

Publications and Research

Background Epstein-Barr virus (EBV) is a common herpesvirus linked to infectious mononucleosis and multiple cancers. There are no national estimates of EBV seroprevalence in the United States. Our objective was to estimate the overall prevalence and sociodemographic predictors of EBV among U.S. children and adolescents aged 6–19. Methods We calculated prevalence estimates and prevalence ratios for EBV seroprevalence using data from the 2003–2010 U.S. National Health and Nutrition Examination Survey (NHANES) for children aged 6–19 (n = 8417). Poisson regression was used to calculate multivariable-adjusted prevalence ratios across subgroup categories (sex, race/ethnicity, parental education, household income, household size, foreign-born, BMI, …

Dating Human Cultural Capacity Using Phylogenetic Principles, J. Lind, P. Lindenfors, S. Ghirlanda, K. Lidén, M. Enquist

Publications and Research

Humans have genetically based unique abilities making complex culture possible; an assemblage of traits which we term “cultural capacity”. The age of this capacity has for long been subject to controversy. We apply phylogenetic principles to date this capacity, integrating evidence from archaeology, genetics, paleoanthropology, and linguistics. We show that cultural capacity is older than the first split in the modern human lineage, and at least 170,000 years old, based on data on hyoid bone morphology, FOXP2 alleles, agreement between genetic and language trees, fire use, burials, and the early appearance of tools comparable to those of modern hunter-gatherers. We …

Earliest Archaeological Evidence Of Persistent Hominin Carnivory, Joseph V. Ferraro, Thomas W. Plummer, Briana L. Pobiner, James S. Oliver, Laura C. Bishop, David R. Braun, Peter W. Ditchfield, John W. Seaman, Katie M. Binetti, John W. Seaman, Fritz Hertel, Richard Potts

Publications and Research

The emergence of lithic technology by ∼2.6 million years ago (Ma) is often interpreted as a correlate of increasingly recurrent hominin acquisition and consumption of animal remains. Associated faunal evidence, however, is poorly preserved prior to ∼1.8 Ma, limiting our understanding of early archaeological (Oldowan) hominin carnivory. Here, we detail three large well-preserved zooarchaeological assemblages from Kanjera South, Kenya. The assemblages date to ∼2.0 Ma, pre-dating all previously published archaeofaunas of appreciable size. At Kanjera, there is clear evidence that Oldowan hominins acquired and processed numerous, relatively complete, small ungulate carcasses. Moreover, they had at least occasional access to the …

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 …

Network Firewall Dynamics And The Subsaturation Stabilization Of Hiv, Bilal Khan, Kirk Dombrowski, Mohamed Saad, Katherine Mclean, Samuel Friedman

Publications and Research

In 2001, Friedman et al. conjectured the existence of a “firewall effect” in which individuals who are infected with HIV, but remain in a state of low infectiousness, serve to prevent the virus from spreading. To evaluate this historical conjecture, we develop a new graph-theoreticmeasure that quantifies the extent towhich Friedman’s firewall hypothesis (FH) holds in a risk network.We compute this new measure across simulated trajectories of a stochastic discrete dynamical system that models a social network of 25,000 individuals engaging in risk acts over a period of 15 years. The model’s parameters are based on analyses of data collected …

Comprehensive Self-Study Submitted By President Jeremy Travis To The Middle States Commission On Higher Education, March 2013., John Jay College Of Criminal Justice

Reports and Publications from John Jay College

Our Self-Study tells a story of institutional transformation. It is not a story driven by accidental circumstances, historical necessity, external forces, or the will of an individual—though each has played a role—but by collective and deliberate analysis of the College’s position in 2005, followed by thoughtful consideration of the future. Institutional change is often, if not always, difficult, but we have learned to pay constant attention to the ever-changing environment and the fixed destination. We have taken advantage of the opportunity offered by the Self-Study to reflect on the past and look toward the future.

The Impact Of Gut Passage By Binturongs (Arctictus Binturong) On Seed Germination, Christina P. Colon, Ahimsa Campos-Arceiz

Publications and Research

Binturongs (Arctictis binturong) are the largest of Asian civets and, due to their highly frugivorous diet, are expected to play an important role in seed dispersal processes. To study the effect of binturong gut passage on seed viability, we fed 10 captive binturongs with fruits of longan (Dimocarpus longan), papaya (Carica papaya) and chiku (Manilkara zapota), collected the seeds they defaecated, and planted these to determine seed germination rate and time. Of the defaecated seeds, 90.4% passed through binturong gut intact in under nine hours, and 99.4% passed in under 33 hours. Chiku seeds had the highest germination rate (35.7% …
