New Skull Material Of Taeniolabis Taoensis (Multituberculata, Taeniolabididae) From The Early Paleocene (Danian) Of The Denver Basin, Colorado, David W. Krause, Simone Hoffman, Tyler R. Lyson, Lindsay G. Dougan, Holger Petermann, Adrienne Tecza, Stephen B. Chester, Ian M. Miller

Publications and Research

Taeniolabis taoensis is an iconic multituberculate mammal of early Paleocene (Puercan 3) age from the Western Interior of North America. Here we report the discovery of significant new skull material (one nearly complete cranium, two partial crania, one nearly complete dentary) of T. taoensis in phosphatic concretions from the Corral Bluffs study area, Denver Formation (Danian portion), Denver Basin, Colorado. The new skull material provides the first record of the species from the Denver Basin, where the lowest in situ specimen occurs in river channel deposits ~730,000 years after the Cretaceous-Paleogene boundary, roughly coincident with the first appearance of legumes …

Dna Extraction And Genotyping From Burned Skeletal Remains, Kayla M. Rooney

Student Theses

In this research, bovine leg bones were burned, both with and without meat intact, in order to determine if it was possible to extract and amplify DNA to obtain profiles. The meat was burned over an open flame and the DNA was extracted using the Qiagen DNeasy Blood & Tissue Mini Kit, quantified with the NanoDrop, and amplified using the Bovine Genotypes Panel 3.1 Kit, and separated using the 3500 Genetic Analyzer. Profiles were analyzed using the Thermo Fisher Cloud Microsatellite Analysis software. The samples burned with the meat intact produced lower quantities of DNA than the bones burned with …

How Phantom Networks, Provider Qualities, And Poverty Sway Medicaid Dental Care Access: A Geospatial Analysis Of Manhattan, Destiny Kelley, Shipeng Sun

Publications and Research

Access to general dental care is essential for preventing and treating oral diseases. To ensure adequate spatial accessibility for the most vulnerable populations, New York State mandates a ratio of one general dentist to 2000 Medicaid recipients within 30 min of public transportation. This study employed geospatial methods to determine whether the requirement is met in Manhattan by verifying the online directories of ten New York managed care organizations (MCOs), which collectively presented 868 available dentists from 259 facilities. Our survey of 118 dental facilities representing 509 dentists revealed that significantly fewer dentists are available to treat Medicaid recipients compared …

Ecological Selectivity And The Evolution Of Mammalian Substrate Preference Across The K–Pg Boundary, Jonathan J. Hughes, Jacob S. Berv, Stephen G. B. Chester, Eric J. Sargis, Daniel J. Field

Publications and Research

The Cretaceous–Paleogene (K–Pg) mass extinction 66 million years ago was characterized by a worldwide ecological catastrophe and rapid species turnover. Large-scale devastation of forested environments resulting from the Chicxulub asteroid impact likely influenced the evolutionary trajectories of multiple clades in terrestrial environments, and it has been hypothesized to have biased survivorship in favour of nonarboreal lineages across the K–Pg boundary. Here, we evaluate patterns of substrate preferences across the K–Pg boundary among crown group mammals, a group that underwent rapid diversification following the mass extinction. Using Bayesian, likelihood, and parsimony reconstructions, we identify patterns of mammalian ecological selectivity that are …

Addressing Structural Racism In The Health Workforce, Randl B. Dent, Anushree Vichare, Jaileessa Casimir

Publications and Research

One of the greatest challenges facing the United States are health inequities among racial/ethnic and other marginalized populations. The deep-rooted structural racism embedded in our social systems, including our health care system and health workforce, is a core cause of racial health inequities. 1 Among many definitions of institutionalized or structural racism, Dr Jones 2 best defines it as: “Differential access to goods, services and opportunities of society by race ... It is structural, having been codified in our institutions of custom, practice, and law, so there need not be an identifiable perpetrator.” Dr Jones further explains that to set …

Detection And Morphological Analysis Of Novel Russian Loanwords, Yulia Spektor

Dissertations, Theses, and Capstone Projects

This paper investigates recent English loanwords in Russian and explores ways in which computational methods can help further theoretical research. The goal of the study is two-fold: to find new, previously unattested loanwords borrowed over the last decade and to examine the rate of adaptation of the new borrowings, attested by the degree to which they conform to the constraints of the Russian language. First, we train a finite-state pipeline that combines character n-gram language models, which encode phonotactic and lexical properties of loanwords, with a binary classifier to detect loanwords. The model achieves state-of-the-art performance results during evaluation, surpassing …

Case 3847 – Simopithecus Oswaldi Andrews, 1916 (Currently Theropithecus Oswaldi; Mammalia, Primates, Cercopithecidae), Proposed Conservation By Reversal Of Precedence With Cynocephalus Atlanticus Thomas, 1884., Eric Delson, David M. Alba, Stephen R. Frost, Dagmawit Abebe Getahun, Christopher C. Gilbert

Publications and Research

The purpose of this application, under Articles 23.9.3 and 81.1 of the Code, is to conserve the usage of the species-group name Simopithecus oswaldi Andrews, 1916 by giving it precedence over its senior subjective synonym Cynocephalus atlanticus Thomas, 1884. Theropithecus is a common to dominant member of the extinct primate community across Africa after 4 million years ago (Jablonski & Frost, 2010) and often co-occurred with extinct humans (Hominini); fossils are also known rarely across Eurasia (Roberts et al., 2014). Most fossil samples are currently included in Theropithecus oswaldi (Andrews, 1916), which is often divided into chrono-geographic subspecies. Cynocephalus atlanticus …

The Case For Public Investment In Higher Pay For New York State Home Care Workers: Estimated Costs And Savings, Isaac Jabola-Carolus, Stephanie Luce, Ruth Milkman

Publications and Research

This report explores one potential solution to the mounting home care labor shortage in New York State: substantially raising wages for the state's home care workers. The analysis presents detailed projections, based on the best available data, of the economic effects of such an intervention, estimating the costs and benefits that would result. We find that public funding to raise home care wages would require significant resources, but those costs would be surpassed by the resulting savings, tax revenues, and economic spillover effects. The net economic gain would total at least $3.7 billion. Lifting wages would also help fill nearly …

Earliest Palaeocene Purgatoriids And The Initial Radiation Of Stem Primates, Gregory P. Wilson Mantilla, Stephen B. Chester, William A. Clemens, Jason R. Moore, Courtney J. Sprain, Brody T. Hovatter, William S. Mitchell, Wade W. Mans, Roland Mundil, Paul R. Renne

Publications and Research

Plesiadapiform mammals, as stem primates, are key to understanding the evolutionary and ecological origins of Pan-Primates and Euarchonta. The Purgatoriidae, as the geologically oldest and most primitive known plesiadapiforms and one of the oldest known placental groups, are also central to the evolutionary radiation of placentals and the Cretaceous-Palaeogene biotic recovery on land. Here, we report new dental fossils of Purgatorius from early Palaeocene (early Puercan) age deposits in northeastern Montana that represent the earliest dated occurrences of plesiadapiforms. We constrain the age of these earliest purgatoriids to magnetochron C29R and most likely to within 105–139 thousand years post- K/Pg …

Prevention In Context: An Examination Of Factors Associated With Recent Hiv Testing Among Men In New York City, Anthony Freeman

Dissertations, Theses, and Capstone Projects

Using intersectionality, Critical Race Theory and Quare theory as theoretical frameworks, this dissertation employs hierarchical logistic regression and data from New York City’s Department of Health and Mental Hygiene (DOHMH) Community Health Survey (CHS) to examine the relative association of key variables and domains -- demographics, sexual characteristics, risk factors and engagement in medical care variables -- on recent HIV testing for a sample of 3997 men. Further, this study explores these effects separately for White, Black, Latino and Asian men.

Findings shows that respondents who were 18-24 years old, 45-64 years old, residing in Queens or Staten Island, employed, …
