Data from Host density and habitat structure influence host contact rates and Batrachochytrium salamandrivorans transmission

2018-08-29-2018-12-15

Batrachochytrium salamandrivorans (Bsal) is an emerging invasive pathogen that is highly pathogenic to salamander species. Modeling infection dynamics in this system can facilitate proactive efforts to mitigate this pathogen’s impact on North American species. Given its widespread distribution and high abundance, the eastern newt (Notophthalmus viridescens) has the potential to significantly influence Bsal epidemiology. We designed experiments to 1) estimate contact rates given different host densities and habitat structure and 2) estimate the probability of transmission from infected to susceptible individuals. Using parameter estimates from data generated during these experiments, we modeled infection and disease outcomes for a population of newts using a system of differential equations. We found that host contact rates were density-dependent, and that adding habitat structure reduced contacts. The probability of Bsal transmission given contact between newts was very high (>90%) even at early stages of infection. Our simulations show rapid transmission of Bsal among individuals following pathogen introduction, with infection prevalence exceeding 90% within one month and >80% mortality of newts in three months. Estimates of basic reproductive rate (R0) of Bsal for eastern newts were 1.9 and 3.2 for complex and simple habitats, respectively. Although reducing host density and increasing habitat complexity might decrease transmission, these management strategies may be ineffective at stopping Bsal invasion in eastern newt populations due to this species’ hyper-susceptibility.

Data from Interpretations of NASA’s MSL Dynamic Albedo of Neutrons Passive Mode Data

2018-01-21-

We analyze Mars Science Laboratory Dynamic Albedo of Neutrons passive mode data. Water equivalent hydrogen content varies along the MSL traverse. DAN passive measurements are consistent with other MSL instruments. DAN passive geochemical indices are presented. The Mars Science Laboratory (Curiosity rover) Dynamic Albedo of Neutrons (DAN) experiment detects neutrons for the purpose of searching for hydrogen in the shallow subsurface of Mars.

Data from Manufactured Disorder: Race, Policing, and Erroneous Ticketing in Chicago

2017-08-2021-11

“Manufactured Disorder” is a case study of Chicago that focuses on parking tickets written under false pretenses. Multiple sources of administrative data are leveraged against one another to identify more than one in eight tickets over a six-year span were written under conditions when restrictions did not apply. The dataset reviews 3,590,005 tickets issued between August 1, 2012 and May 18, 2018, narrowing its attention to seven different types of parking restrictions that specify circumstantial conditions of compliance. These seven types of tickets were purposefully selected on the basis that their validity could be corroborated (or contested) by data routinely maintained by the City of Chicago (e.g., street cleaning schedules, residential parking zone, special event permits, etc.). The data are hierarchal insofar as they contain units of measure at the ticket-, issuing officer-, and tract- levels, although the data structure follows a partially crossed orientation (i.e., tickets are nested in officer- and tract- level units, but ticketing patterns of issuing officers are not restricted by neighborhood)., Henricks, Kasey. 2022.

Data from Mental Health, Weather Extremes, and Race study

2016-08-01-2016-11-30

Data are from a randomly-sampled survey in lower-to-moderate income Census tracts in Knoxville, Tennessee. Variables include demographics, self-reported physical and mental health impacts of seasonal weather extremes, social cohesion, preparedness, and concern about climate change.

Data from NSF Award #1155339: Governance of International Labor Migration: Scalar Politics and Network Relations

The deposited documents are created for a project funded by the National Science Foundation on the governance of international labor migration: politics of scale and networks (Award #1155339). The site contains transcripts of interviews with stakeholders in international skilled migration, a survey conducted with foreign-born engineers and information technology specialists in two petroleum-related companies and two information technology companies, survey codes, a project web site, research presentations, and a project-related publication.

Data from New Age Estimates and Microscopic Charcoal Data for the 1976-B Core from Anderson Pond, Tennessee, USA

The deposited data include new estimated ages along with microscopic charcoal data for a sediment core from Anderson Pond, Tennessee, recovered in 1976 by H.R. Delcourt (Ecological Monographs 49:255–280, 1979). These data supplement the paper by S.P. Horn, M.S. Boehm, and J.P. Ballard, "An improved chronology for the microscopic charcoal and pollen records from Anderson Pond, Tennessee, USA" (Palynology, forthcoming). The microscopic charcoal data were developed under NSF grant #0822824 to Sally Horn and Zheng-Hua Li. The new age estimates build upon research supported by that award and by NSF grants #0823131 to Steven Driese and #0716951 to Stephen Jackson.

Data from Public Progress, Data Management and the Land Grant Mission

This article reports results from a survey about data management practices and attitudes sent to agriculture researchers and extension personnel at the University of Tennessee Institute of Agriculture (UTIA) and the College of Agricultural Sciences and Warner College of Natural Resources at Colorado State University. Results confirm agriculture researchers, like many other scientists, continue to exhibit data management practices that fall short of generally accepted best practices. In addition, librarians, and others seeking to influence future behavior, may be informed by our finding of a relationship between the land-grant mission and researchers’ data management practices., Fernandez, P., Eaker, C., Swauger, S., & Davis, M., "Data from Public Progress, Data Management and the Land Grant Mission" (2016). http://dx.doi.org/10.7290/V7KS6PHQ.

Data from Tasmanian Eucalyptus Plant Functional Trait and Herbivory Data

Gorman, Courtney Ethe, "Tasmanian Eucalyptus Plant Functional Trait and Herbivory Data" (2014). http://dx.doi.org/10.7290/V7F769GZ, This is a dataset of commonly measured plant functional traits (height, internode length, leaf thickness, and specific leaf area) and herbivore responses (insect and mammalian) to those traits used for a comparitive analyses of endemic versus non-endemic Eucalyptus species.

Data from The State of Social Media Policies in Higher Education

This dataset is from the paper "The State of Social Media Policies in Higher Education." This paper presents an analysis of the current state of development of social media policies at institution of higher education. Content analysis of social media policies for all institutions listed in the Carnegie Classification Data File revealed that less than one- quarter of institutions had an accessible social media policy. Analysis was done by institution and campus unit, finding that social media policies were most likely to appear at doctorate-granting institutions and health, athletics, and library units. Policies required that those affiliated with the institution post appropriate content, represent the unit appropriately, and moderate conversations with coworkers and external agencies. This analysis may inform the development and revision of social media policies across the field of higher education, taking into consideration the rapidly changing landscape of social media, issues of academic freedom, and notions of interoperability with policies at the unit and campus levels.
