New Homes, Different Places : Demographic Transitions In The Worcester County Ma Foster Care System : A Project Based Upon An Investigation At Y.O.U., Inc. Foster Care Program In Worcester Ma, Anne Wassell Hopkinson

Theses, Dissertations, and Projects

This case study examines the broader trends in demographic change experienced by children in the foster care system in Worcester County, Massachusetts by comparing information regarding removal and placement locations of youth in the Y.O.U., Inc. foster care program with 2000 census data describing the poverty levels, household incomes and racial composition of these locations. The findings demonstrate that children were likely to be removed from areas with high levels of poverty and low numbers of non-Hispanic white residents and placed into areas with low levels of poverty and high numbers of non-Hispanic white populations. This demographic analysis is contextualized …

The Conflicts In Yemen And U.S. National Security, W. Andrew Terrill Dr.

Books, Monographs & Collaborative Studies

Yemen is not currently a failed state, but it is experiencing huge political and economic problems that can have a direct impact on U.S. interests in the region. It has a rapidly expanding population with a resource base that is limited and already leaves much of the current population in poverty. The government obtains around a third of its budget revenue from sales of its limited and declining oil stocks, which most economists state will be exhausted by 2017. Yemen also has critical water shortages and a variety of interrelated security problems. In Sa’ada province in Yemen’s northern mountainous region, …

Estimating Hydraulic Conductivity For The Martian Subsurface Based On Drainage Patterns — A Case Study In The Mare Tyrrhenum Quadrangle, Wei Luo, Bartosz Grudzinski, Darryll T. Pederson

Department of Earth and Atmospheric Sciences: Faculty Publications

Hydraulic conductivity K, as the coefficient of proportionality in Darcy’s Law, is critical in understanding the past Martian hydrologic cycle, climate, and landform evolution. However, K and its spatial variability on Mars are thus far poorly constrained due to lack of accessibility. Using an innovative method based on surface drainage dissection patterns, which has been successfully tested in the Oregon Cascades on Earth, we estimated K in the Mare Tyrrhenum Quadrangle on Mars. The basic assumption is that under long-term dynamic equilibrium conditions, the overall dissection pattern in a watershed as reflected in drainage density is controlled by the …

Late Pleistocene Dune Activity In The Central Great Plains, Usa, Joseph A. Mason, James B. Swinehart, Paul R. Hanson, David Loope, Ronald J. Goble, Xiaodong Miao, Rebecca L Schmeisser

Department of Earth and Atmospheric Sciences: Faculty Publications

Stabilized dunes of the central Great Plains, especially the megabarchans and large barchanoid ridges of the Nebraska Sand Hills, provide dramatic evidence of late Quaternary environmental change. Episodic Holocene dune activity in this region is now well-documented, but Late Pleistocene dune mobility has remained poorly documented, despite early interpretations of the Sand Hills dunes as Pleistocene relicts. New optically stimulated luminescence (OSL) ages from drill cores and outcrops provide evidence of Late Pleistocene dune activity at sites distributed across the central Great Plains. In addition, Late Pleistocene eolian sands deposited at 20–25 ka are interbedded with loess south of the …

A Dual-Network Testbed For Wireless Sensor Applications, Jedrzej Kowalczuk, Mehmet C. Vuran, Lance C. Pérez

A dual-network Cyber-physical Networking (CPN) testbed developed at the University of Nebraska-Lincoln is described. The CPN testbed consists of two geographically disparate wireless sensor networks connected by a traditional TCP/IP network and enables peer-to-peer communication between each sensor in the network. The functionality of the testbed is enhanced by a range of software tools that support remote programming and network monitoring, and real-time visualization of sensor data. The resulting architecture supports easy deployment and evaluation of applications for both traditional and interconnected wireless sensor networks. To demonstrate the features of this testbed, a novel ping application was developed and deployed …

Demonstration Of A Conceptual Model For Using Lidar To Improve The Estimation Of Floodwater Mitigation Potential Of Prairie Pothole Region Wetlands, Shengli Huang, Claudia Young, Min Feng, Karl Heidemann, Matthew Cushing, David M. Mushet, Shuguang Liu

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Recent flood events in the Prairie Pothole Region of North America have stimulated interest in modeling water storage capacities of wetlands and their surrounding catchments to facilitate flood mitigation efforts. Accurate estimates of basin storage capacities have been hampered by a lack of high-resolution elevation data. In this paper, we developed a 0.5 m bare-earth model from Light Detection And Ranging (LiDAR) data and, in combination with National Wetlands Inventory data, delineated wetland catchments and their spilling points within a 196 km² study area. We then calculated the maximum water storage capacity of individual basins and modeled the connectivity …

Heat Waves Measured With Modis Land Surface Temperature Data Predict Changes In Avian Community Structure, Thomas P. Albright, Anna M. Pidgeon, Chadwick D. Rittenhouse, Murray K. Clayton, Curtis H. Flather, Patrick D. Culbert, Volker C. Radeloff

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Heat waves are expected to become more frequent and severe as climate changes, with unknown consequences for biodiversity. We sought to identify ecologically-relevant broad-scale indicators of heat waves based on MODIS land surface temperature (LST) and interpolated air temperature data and assess their associations with avian community structure. Specifically, we asked which data source, time periods, and heat wave indices best predicted changes in avian abundance and species richness. Using mixed effects models, we analyzed associations between these indices and data from the North American Breeding Bird Survey in the central United States between 2000 and 2007 in four ecoregions …

Forest Structure And Aboveground Biomass In The Southwestern United States From Modis And Misr, Mark Chopping, Crystal B. Schaaf, Feng Zhao, Zhuosen Wang, Anne Nolin, Gretchen G. Moisen, John V. Martonchik, Michael Bull

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Red band bidirectional reflectance factor data from the NASA MODerate resolution Imaging Spectroradiometer (MODIS) acquired over the southwestern United States were interpreted through a simple geometric–optical (GO) canopy reflectance model to provide maps of fractional crown cover (dimensionless), mean canopy height (m), and aboveground woody biomass (Mg ha⁻¹) on a 250 m grid. Model adjustment was performed after dynamic injection of a background contribution predicted via the kernel weights of a bidirectional reflectance distribution function (BRDF) model. Accuracy was assessed with respect to similar maps obtained with data from the NASA Multiangle Imaging Spectroradiometer (MISR) and to contemporaneous …

White-Tailed Deer Incidents With U.S. Civil Aircraft, Kirsten M. Biondi, Jerrold L. Belant, James A. Martin, Travis L. Devault, Guiming Wang

United States Department of Agriculture Wildlife Services: Staff Publications

Aircraft incidents with ungulates cause substantial economic losses and pose risks to human safety. We analyzed 879 white-tailed deer (Odocoileus virginianus) incidents with United States civil aircraft from 1990 to 2009 reported in the Federal Aviation Administration National Wildlife Strike Database. During that time, deer incidents followed a quadratic response curve, peaking in 1994 and declining thereafter. There appeared to be some seasonal patterning in incident frequency, with deer incidents increasing overall from January to November, and peaking in October and November (30.7%). Most incidents (64.8%) occurred at night, but incident rates were greatest (P 0.001) at dusk. Landing-roll represented …

Well-designed web-based (online) lessons should reinforce the critical need of the soil science discipline in today's food, energy, and environmental issues, as well as meet the needs of the diverse clientele with interest in agricultural and/ or environmental disciplines. The objectives of the project were to: (1) develop web-based lessons in soil genesis and development and (2) evaluate context-based case studies or application lessons (agronomic, environmental, and ecological situations) to teach soil genesis and development. Six principles lessons, along with three applications lessons, were developed …

Male Field Crickets Infested By Parasitoid Flies Express Phenotypes That May Benefit The Parasitoids, Oliver M. Beckers, William E. Wagner

School of Biological Sciences: Faculty Publications

Parasites can cause changes in the phenotypes of their hosts that may benefit the parasite, the host, or both. To understand the evolutionary dynamics of host–parasite interactions it is necessary to first examine the effect of parasitic infestation on the host phenotype and whether the host or parasite benefits from these changes. The fly Ormia ochracea parasitizes the variable field cricket, Gryllus lineaticeps, and it uses male song to locate hosts for its lethal larvae. Adult flies preferentially orient to male songs with faster and longer chirps. We tested the effect of larval infestation on two types of host traits. …

Foreword, From Holy Places And Pilgrimages: Essays On India, Robert H. Stoddard

Geography Program: Faculty Publications

This collection of twelve articles continues a long and rich body of information about pilgrimages. Written materials in the form of pamphlets, guidebooks, manuals, itineraries, and treatises about pilgrimages date from antiquity (see, e.g. the discussion in this volume by Rana Singh about ancient epics, pp. 15-20). Travelling to places regarded by worshippers as having extraordinary spiritual power is a phenomenon permeating all religious traditions so it is logical that it appears in various literary forms.

Evaluation Of The Modis Lai Product Using Independent Lidar-Derived Lai: A Case Study In Mixed Conifer Forest, Jennifer L.R. Jensen, Karen S. Humes, Andrew T. Hudak, Lee A. Vierling, Eric Delmelle

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

This study presents an alternative assessment of the MODIS LAI product for a 58,000 ha evergreen needleleaf forest located in the western Rocky Mountain range in northern Idaho by using lidar data to model (R²=0.86, RMSE=0.76) and map LAI at higher resolution across a large number of MODIS pixels in their entirety. Moderate resolution (30 m) lidar-based LAI estimates were aggregated to the resolution of the 1-km MODIS LAI product and compared to temporally-coincident MODIS retrievals. Differences in the MODIS and lidar-derived values of LAI were grouped and analyzed by several different factors, including MODIS retrieval algorithm, sun/sensor …

Socio-Economic Impacts Of Climate Change On Rural United States, Pankaj Lal, Janaki R. R. Alavalapati, Evan D. Mercer

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Directly or indirectly, positively or negatively, climate change will affect all sectors and regions of the United States. The impacts, however, will not be homogenous across regions, sectors, population groups or time. The literature specifically related to how climate change will affect rural communities, their resilience, and adaptive capacity in the United States (U.S.) is scarce. This article bridges this knowledge gap through an extensive review of the current state of knowledge to make inferences about the rural communities vulnerability to climate change based on Intergovernmental Panel on Climate Change (IPCC) scenarios. Our analysis shows that rural communities tend to …

Annual Seroprevalence Of Yersinia Pestis In Coyotes As Predictors Of Interannual Variation In Reports Of Human Plague Cases In Arizona, United States, Heidi E. Brown, Craig E. Levy, Russell E. Enscore, Martin E. Schriefer, Thomas J. Deliberto, Kenneth L. Gage, Rebecca J. Eisen

United States Department of Agriculture Wildlife Services: Staff Publications

Although several health departments collect coyote blood samples for plague surveillance, the association between reported human cases and coyote seroprevalence rates remains anecdotal. Using data from an endemic region of the United States, we sought to quantify this association. From 1974 to 1998, about 2,276 coyote blood samples from four Arizona counties were tested for serological evidence of exposure to Yersinia pestis, the causative agent of plague. Using a titer threshold presumed to be indicative of recent infection (serum titers of ≥1:256), we found a statistically significant relationship between years with > 17% sero-positive coyotes and years with two or …

Phylogenetic And Population Genetic Assessment Of Rafinesque’S Big-Eared Bat (Corynorhinus Rafinesquii), Antoinette J. Piaggio, David A. Saugey, D. Blake Sasse

United States Department of Agriculture Wildlife Services: Staff Publications

Rafinesque’s big-eared bat (Corynorhinus rafinesquii) is distributed across the Southeastern United States. Due to habitat loss and low population numbers, this species is a Federal species of concern and protected by every State within its range. Effective management of any species of concern is dependent on an unambiguous understanding of taxonomic relationships. However, for this species, there are discordant inferences about subspecific designations from previous studies. Further, there have been no assessments of population genetic status for this species. Such assessments could provide information on genetic diversity and population connectivity and increase our understanding of the need for …

Genetic Applications In Avian Conservation, Susan M. Haig, Whitcomb M. Bronaugh, Rachel S. Crowhurst, Jesse D'Elia, Collin A. Eagles-Smith, Clinton W. Epps, Brian Knaus, Mark P. Miller, Michael L. Moses, Sara Oyler-Mccance, W. Douglas Robinson, Brian Sidlauskas

United States Geological Survey: Staff Publications

A fundamental need in conserving species and their habitats is defining distinct entities that range from individuals to species to ecosystems and beyond (Table 1; Ryder 1986, Moritz 1994, Mayden and Wood 1995, Haig and Avise 1996, Hazevoet 1996, Palumbi and Cipriano 1998, Hebert et al. 2004, Mace 2004, Wheeler et al. 2004, Armstrong and Ball 2005, Baker 2008, Ellis et al. 2010, Winker and Haig 2010). Rapid progression in this interdisciplinary field continues at an exponential rate; thus, periodic updates on theory, techniques, and applications are important for informing practitioners and consumers of genetic information. Here, we outline conservation …

Effects Of Free Trade Areas In Trade Promotion: Gravity Model Approach, Mona Jit Mui Lim

Dissertations and Theses Collection (Open Access)

Since the early 1990s, the world has seen a proliferation of Free Trade Agreements (FTAs). One of the key objectives of FTAs is to expand trade between or amongst its signatories. This study explores the intra-FTA and extra-FTA trade expansion capability of 3 types of FTA: North-North FTA (European Union (EU)-15 as a representative), North-South FTA (North America Free Trade Agreement (NAFTA) as a representative) and South-South FTA (Association of Southeast Asia Nations (ASEAN ) Free Trade Agreement (AFTA) as a representative). The study made an attempt to address the spread of such FTA-led trade expansion amongst the members and …

Foreword: Rulemaking, Democracy, And Torrents Of E-Mail, Nina A. Mendelson

Articles

This Foreword is meant as an initial foray into the question of what agencies should do with mass public comments, particularly on broad questions of policy. Part I discusses the extent to which congressional control, presidential control, and agency procedures themselves can ensure that agency decisions are democratically responsive. In view of shortcomings in both congressional and presidential control, I underscore the need to focus closely on rulemaking procedures as a source of democratic responsiveness. The possibility that agencies may be systematically discounting certain public submissions raises difficulties, and I present some examples. Part II makes a preliminary case that …

Behavior Constrains The Dispersal Of Long-Lived Spiny Lobster Larvae, Mark J. Butler Iv, Claire B. Paris, Jason S. Goldstein, Hirokazu Matsuda, Robert K. Cowen

Biological Sciences Faculty Publications

Behavior such as ontogenetic vertical migration (OVM) limits the transport of marine larvae with short pelagic larval durations (PLDs), but its effect on the supposed long-distance dispersal of larvae with long PLDs is unknown. We conducted laboratory tests of ontogenetic change in larval phototaxis and examined size-specific patterns of larval distribution in the plankton to characterize OVM in the Caribbean spiny lobster Panulirus argus during its long (6 mo) PLD. We then used a coupled biophysical model to explore the consequences of OVM and hydrodynamics on larval P. argus dispersal in the Caribbean Sea. Larvae reared in the laboratory were …

Conservation Status Of Marine Biodiversity In Oceania: An Analysis Of Marine Species On The Iucn Red List Of Threatened Species, Beth A. Polidoro, Cristiane T. Elfes, Jonnell C. Sanciangco, Helen Pippard, Kent E. Carpenter

Biological Sciences Faculty Publications

Given the economic and cultural dependence on the marine environment in Oceania and a rapidly expanding human population, many marine species populations are in decline and may be vulnerable to extinction from a number of local and regional threats. IUCN Red List assessments, a widely used system for quantifying threats to species and assessing species extinction risk, have been completed for 1190 marine species in Oceania to date, including all known species of corals, mangroves, seagrasses, sea snakes, marine mammals, sea birds, sea turtles, sharks, and rays present in Oceania, plus all species in five important perciformfish groups. Many of …
