Fourteen New, Endemic Species Of Shrew (Genus Crocidura) From Sulawesi Reveal A Spectacular Island Radiation, Jacob A. Esselstyn, Anang S. Achmadi, Heru Handika, Mark T. Swanson, Thomas C. Giarla, Kevin C. Rowe

Faculty Publications

After nearly a decade of field inventories in which we preserved voucher specimens of the small terrestrial mammals of Sulawesi, we combined qualitative and quantitative analyses of morphological traits with molecular phylogenetics to better understand the diversity of shrews (Soricidae: Crocidura) on the island. We examined the morphology of 1368 specimens and obtained extensive molecular data from many of them, including mitochondrial DNA sequences from 851 specimens, up to five nuclear exons from 657 specimens, and thousands of ultraconserved elements from 90 specimens. By iteratively testing species limits using distinct character datasets and appropriate taxon sampling, we found clear, mostly …

A Novel Big Data Approach To Measure And Visualize Urban Accessibility, Yuqin Jiang, Diansheng Guo, Zhenlong Li, Michael E. Hodgson

Faculty Publications

Accessibility is a topic of interest to multiple disciplines for a long time. In the last decade, the increasing availability of data may have exceeded the development of accessibility modeling approaches, resulting in a modeling gap. In part, this modeling gap may have resulted from the differences needed for single versus multimodal opportunities for access to services. With a focus on large volumes of transportation data, a new measurement approach, called Urban Accessibility Relative Index (UARI), was developed for the integration of multi-mode transportation big data, including taxi, bus, and subway, to quantify, visualize and understand the spatiotemporal patterns of …

Impact Of Metropolization On The Crime Structure (Case Study Of Provincial Capitals In Poland), Natalia Sypion-Dutkowska, Michael Leitner, Marek Dutkowski

Faculty Publications

The aim of this study is to verify the hypothesis that the rapid metropolization process that has been taking place in large Polish cities since the beginning of the second phase of post-communist transition in 2000 leads to their socio-economic diversity, which is manifested, among others, in the differentiation of the level and structure of crime. Introduced into the discourse of this paper are subsequent stages of metropolization, which are called potential, initiating, advanced, and mature and which the examined cities have achieved so far. These stages have led to various economic and social effects, which resulted in changes in …

Experimental Investigation Of The Aerodynamics Of A Large Industrial Building With Parapet, Aly Mousaad Aly, Matthew Thomas, Hamzeh Gol-Zaroudi

Faculty Publications

The aerodynamic performance of a roof depends significantly on its shape and size, among other factors. For instance, large roofs of industrial low-rise buildings may behave differently compared to those of residential homes. The main objective of this study is to experimentally investigate how perimeter solid parapets can alter the flow pattern around a low-rise building with a large aspect ratio of width/height of about 7.6, the case of industrial buildings/shopping centers. Solid parapets of varied sizes are added to the roof and tested in an open-jet simulator in a comparative study to understand their impact on roof pressure coefficients. …

Assessing Population Exposure To Coastal Flooding Due To Sea Level Rise, Matthew E. Hauer, Dean Hardy, Scott A. Kulp, Valerie Mueller, David J. Wrathall, Peter U. Clark

Faculty Publications

The exposure of populations to sea-level rise (SLR) is a leading indicator assessing the impact of future climate change on coastal regions. SLR exposes coastal populations to a spectrum of impacts with broad spatial and temporal heterogeneity, but exposure assessments often narrowly define the spatial zone of flooding. Here we show how choice of zone results in differential exposure estimates across space and time. Further, we apply a spatio-temporal flood-modeling approach that integrates across these spatial zones to assess the annual probability of population exposure. We apply our model to the coastal United States to demonstrate a more robust assessment …

Challenges For Estimating The Global Prevalence Of Micronutrient Deficiencies And Related Disease Burden: A Case Study Of The Global Burden Of Disease Study, Sonja Y. Hess, Alexander C. Mclain, Edward A. Frongillo Jr., Ashkan Afshin, Nicholas J. Kassebaum, Saskia J. Osendarp, Reed Atkin, Rahul Rawat, Kenneth H. Brown

Faculty Publications

Information on the prevalence of micronutrient deficiencies is needed to determine related disease burden; underpin evidence-based advocacy; and design, deliver, and monitor safe, effective interventions. Assessing the global prevalence of deficiency requires a valid micronutrient status biomarker with an appropriate cutoff to define deficiency and relevant data from representative surveys across multiple locations and years. The Global Burden of Disease Study includes prevalence estimates for iodine, iron, zinc, and vitamin A deficiencies, for which recommended biomarkers and appropriate deficiency cutoffs exist. Because representative survey data are lacking, only retinol concentration is used to model vitamin A deficiency, and proxy indicators …

Use Of Racial And Ethnic Categories In Medical Testing And Diagnosis: Primum Non Nocere, Jay S. Kaufman, Joanna Merckx, Richard S. Cooper

Faculty Publications

BACKGROUND: Use of race and ethnicity is common in medical tests and procedures, even though these categories are defined by sociological, historical, and political processes, and vary considerably in their definitions over time and place. Because all societies organize themselves around these constructs in some way, they are undeniable facets of the human experience, with myriad health consequences. In the biomedical literature, they are also commonly interpreted as representing biological heterogeneity that is relevant for health and disease. CONTENT: We review the use of race and ethnicity in medical practice, especially in the USA, and provide 2 specific examples to …

Atmospheric Circulation Regimes For Prescribed Burns Along The U.S. Gulf Of Mexico Coast, Wenjia Cao, Robert V. Rohli, Fenglin Han, Anthony J. Vega, Nazla Bushra, John A. Nyman

Faculty Publications

The regional-to-synoptic-scale steering atmospheric circulation is important for advecting energy, mass, and momentum across space, with the near-surface wind being the local manifestation of this circulation. The local winds can affect phenomena of economic, ecological, and/or aesthetic values, such as bird migrations and prescribed burns to restore bird habitats. The purpose of this research is to classify the days from 1979 to 2018 based on circulation patterns near the surface (i.e., 1000-hPa) and at the highest level of airflow affecting bird migration (i.e., 700-hPa), across the Gulf Coast region of the United States. The resulting patterns, derived from Ward's clustering …

And The Heat Goes On: Police Repression And The Modalities Of Power, Howard Liu, Christopher M. Sullivan

Faculty Publications

Among security institutions, police occupy a unique position. In addition to specializing in the repression of dissent, police monitor society and enforce order. Yet within research studying state repression, how police institutions are used and deployed to control domestic threats remain under-explored, particularly as it relates to the dual functionality just described. In this study, we develop and test an explanation of police repression accounting for the bifurcation of Mann’s two modalities of state power: infrastructural power and despotic power. Infrastructural power allocates police resources to surveil dissidents and preemptively limit dissent’s emergence or escalation. Police deploy despotic power through …

Shape-Based Classification Of Partially Observed Curves, With Applications To Anthropology, Gregory J. Matthews, Karthik Bharath, Sebastian Kurtek, Juliet K. Brophy, George K. Thiruvathukal, Ofer Harel

Faculty Publications

We consider the problem of classifying curves when they are observed only partially on their parameter domains. We propose computational methods for (i) completion of partially observed curves; (ii) assessment of completion variability through a nonparametric multiple imputation procedure; (iii) development of nearest neighbor classifiers compatible with the completion techniques. Our contributions are founded on exploiting the geometric notion of shape of a curve, defined as those aspects of a curve that remain unchanged under translations, rotations and reparameterizations. Explicit incorporation of shape information into the computational methods plays the dual role of limiting the set of all possible completions …

The Individual Water Insecurity Experiences (Iwise) Scale: Reliability, Equivalence And Validity Of An Individual-Level Measure Of Water Security, Sera L. Young, Hilary J. Bethancourt, Zacchary R. Ritter, Edward A. Frongillo Jr.

Faculty Publications

Objective: The lack of a validated and cross-culturally equivalent scale for measuring individual-level water insecurity has prevented identification of those most vulnerable to it. Therefore, we developed the 12-item Individual Water InSecurity Experiences (IWISE) Scale to comparably measure individual experiences with access, use, and stability (reliability) of water. Here, we examine the reliability, cross-country equivalence, and cross-country and within-country validity of the scale in a cross-sectional sample.

Methods: IWISE items were implemented by the Gallup World Poll among nationally representative samples of 43 970 adults (15 y) in 31 low-income and middle-income countries (LMICs). Internal consistency was assessed …

Faculty Publications

In 2010, the Deepwater Horizon oil spill released an estimated 4.9 million barrels of oil into the Gulf of Mexico, damaging coastal ecosystems. Seaside Sparrows (Ammospiza maritima)—a year-round resident of Gulf Coast salt marshes—were exposed to oil, as shown by published isotopic and molecular analyses, but fitness consequences have not been clarified. We monitored nests around two bays in Plaquemines Parish, Louisiana, USA from 2012–2017 to assess possible impacts on the nesting biology of Seaside Sparrows. A majority of nests failed (76% of known-fate nests, N = 252 nests, 3521 exposure-days) during our study, and predation was the main cause …

Insights Into The Tectonostratigraphic Setting Of The Southern Appalachians During The Blountian Tectophase From An Integrated Geochemical Analysis Of Magmatic Phenocrysts In The Ordovician Deicke K-Bentonite, Achim D. Herrmann, John T. Haynes, Richard M. Robinet, Jürgen Konzett, Norlene R. Emerson

Faculty Publications

We evaluate competing hypotheses regarding tectonic models of the early Taconic Orogeny in the Southern Appalachians during the Blountian tectophase with new geochemical data obtained from analyses of apatite and zircon phenocrysts, and melt and mineral inclusions therein, from the Ordovician Deicke K-bentonite (453.35 ± 0.10 Ma). Apatite geochemistry confirms that samples from different locations represent the same eruptive event, and zircon geochemistry and U[sbnd]Pb geochronology (including several Grenville-age inherited detrital cores) confirm an evolved magma of continental-arc composition, with the trace-metal geochemistry of magmatic Taconic-age rims on Deicke zircons pointing to a provenance of continental crustal igneous rock melts, …

Bulk Scanning Method Of A Heavy Metal Concentration In Tailings Of A Gold Mine Using Swir Hyperspectral Imaging System, Yongsik Jeong, Jaehyung Yu, Lei Wang, Kwang Jae Lee

Faculty Publications

This work introduces a bulk data acquisition method using a hyperspectral imaging system (HIS) to measure chromium (Cr) concentration in the soil samples obtained from tailings of a gold mine considering of the spectral competition between heavy metal elements. The chemical, mineralogical, and spectroscopic analyses in a laboratory environment revealed that heavy metal elements' competitive geochemical behaviors were manifested as spectral competitions between heavy metal elements in tailings. The heavy metal elements can be classified into two groups based on their geochemical behaviors: chromium-nickel (Cr-Ni) and zinc-arsenic-cadmium-lead (Zn-As-Cd-Pb). We found an inverse relationship between the two groups in their spectral …
