Design
Ecological study.

Setting
St. Louis, Missouri.

Exposure measure
Blood lead levels.

Main outcome measure
Official reports of violent crimes were categorized as 1) crimes involving a firearm (yes/no), 2) assault crimes (with or without a firearm), 3) robbery crimes (with or without a …


Cross-Modal Recognition Of Familiar Conspecifics In Goats, Benjamin J. Pitcher, Elodie F. Briefer, Luigi Baciadonna, Alan G. Mcelligott Nov 2017

Cross-Modal Recognition Of Familiar Conspecifics In Goats, Benjamin J. Pitcher, Elodie F. Briefer, Luigi Baciadonna, Alan G. Mcelligott

Alan G. McElligott, PhD

When identifying other individuals, animals may match current cues with stored information about that individual from the same sensory modality. Animals may also be able to combine current information with previously acquired information from other sensory modalities, indicating that they possess complex cognitive templates of individuals that are independent of modality. We investigated whether goats (Capra hircus) possess cross-modal representations (auditory–visual) of conspecifics. We presented subjects with recorded conspecific calls broadcast equidistant between two individuals, one of which was the caller. We found that, when presented with a stablemate and another herd member, goats looked towards the caller sooner and …

Surface-Soil Properties Of Alder Balds With Respect To Grassy And Rhododendron Balds On Roan Mountain, North Carolina—Tennessee, James T. Donaldson, Zachary C. Dinkins, Foster Levy, Arpita Nandi Aug 2017

Surface-Soil Properties Of Alder Balds With Respect To Grassy And Rhododendron Balds On Roan Mountain, North Carolina—Tennessee, James T. Donaldson, Zachary C. Dinkins, Foster Levy, Arpita Nandi

Foster Levy

We analyzed soils in Alder Bald, Grassy Bald, and Rhododendron Bald communities on Roan Mountain to infer the influence of vegetation on soil and to help guide management strategies. In all vegetation types, soils were acid (pH = 4–5) sandy loams. We found vegetation-associated differences for organic content, cation exchange capacity, acidity, two plant macronutrients (K, Mg), and three cations (Fe, Na, Zn). We predicted that nitrogen compounds would be highest in the Alder Bald because Alnus viridis ssp. crispa (Green Alder) can harbor nitrogen-fixing bacteria. Organic content was highest at the alder-bald sites, ammonium was similar among vegetation types, …


Pattern And Rate Of Decline Of A Population Of Carolina Hemlock (Tsuga Caroliniana Engelm.) In North Carolina, Foster Levy, Elaine S. Walker Aug 2017

Pattern And Rate Of Decline Of A Population Of Carolina Hemlock (Tsuga Caroliniana Engelm.) In North Carolina, Foster Levy, Elaine S. Walker

Foster Levy

We monitored a population of Carolina Hemlocks in northwestern North Carolina for four years to examine the rate and pattern of decline in response to infestation by Adelges tsugae (Hemlock Woolly Adelgid). Our yearly census of hemlock condition and severity of the adelgid infestation included trees of all sizes. We estimated declines in condition as the portions of the leaf canopy that were lost. Initially, infestation occurred throughout the population but was severe in only a small cluster of individuals. Within 1 year, the area of severe infestation increased in size to encompass 48% of the population. In another region …


Encouraging Our Youngest Students To Think Like Scientists: Exploring Elementary Teachers' Experiences Of Teaching Disciplinary Literacy, Jacy Ippolito, Cami Condie Mar 2017

Encouraging Our Youngest Students To Think Like Scientists: Exploring Elementary Teachers' Experiences Of Teaching Disciplinary Literacy, Jacy Ippolito, Cami Condie

Jacy Ippolito

Elementary teachers today must provide more, and better, instruction in the content areas for their students than ever before. Many argue that the best place to teach comprehension is within the content areas, where literacy and content knowledge can be simultaneously developed (Moje, 2015; NRP, 2000; Pearson, Moje, & Greenleaf, 2010). The Common Core State Standards (NGA Center & CCSSO, 2010) suggest that for all students across all content areas, teachers must know how to provide a bridge for students to access content through literacy, while simultaneously supporting meaningful literacy development through rich content-area texts. However, experts in the content …


Disability And Accessibility In The Library And Information Science Literature: A Content Analysis, Heather Hill Jan 2017

Disability And Accessibility In The Library And Information Science Literature: A Content Analysis, Heather Hill

Heather Hill

The library profession is often a strong and vocal proponent of increased access for persons with disabilities. With the profession's long-standing interest in the subject of services to persons with disabilities come questions that get to how the profession perceives the phenomenon. How is library and information science (LIS), as a field, conceptualizing disability and accessibility? The space for examining this question is a content analysis of the LIS literature. The literature provides a fertile ground for study as it reflects the profession's approaches to, and perceptions of, a topic. This research identifies the major issues and trends in the …


Combined And Synergistic Effects Of Climate Change And Urbanization On Water Quality In The Wolf Bay Watershed, Southern Alabama, Ruoyu Wang Jan 2017

Combined And Synergistic Effects Of Climate Change And Urbanization On Water Quality In The Wolf Bay Watershed, Southern Alabama, Ruoyu Wang

Ruoyu Wang

This study investigated potential changes in flow, total suspended solid (TSS) and nutrient (nitrogen and phosphorous) loadings under future climate change, land use/cover (LULC) change and combined change scenarios in the Wolf Bay watershed, southern Alabama, USA. Four Global Circulation Models (GCMs) under three Special Report Emission Scenarios (SRES) of greenhouse gas were used to assess the future climate change (2016–2040). Three projected LULC maps (2030) were employed to reflect different extents of urbanization in future. The individual, combined and synergistic impacts of LULC and climate change on water quantity/quality were analyzed by the Soil and Water Assessment Tool (SWAT). …


Racial/Ethnic Minority Segregation And Low Birth Weight: A Comparative Study Of Chicago And Toronto Community-Level Indicators, Fernando De Maio, Raj C. Shah, Kellie Schipper, Realino Gurdiel, David Ansell Dec 2016

Racial/Ethnic Minority Segregation And Low Birth Weight: A Comparative Study Of Chicago And Toronto Community-Level Indicators, Fernando De Maio, Raj C. Shah, Kellie Schipper, Realino Gurdiel, David Ansell

Fernando De Maio

We examined the association between racial/ethnic minority segregation and low birth weight (LBW) in Chicago and Toronto communities. While previous work has documented the importance of contextual effects on LBW, these studies have usually been conducted within a single city. We used Pearson correlation coefficients and OLS regression models to examine potential variability in the association between racial/ethnic minority segregation and LBW in Chicago (N = 77 communities) and Toronto (N = 140 communities). Results indicate that racial/ethnic minority segregation, unemployment, and low educational attainment are not associated with LBW in Toronto, while these indicators have strong and significant associations …
