Detecting Environmental Change: How Many Samples Are Required?, M. J. Gardner, S. D.W. Comber

School of Geography, Earth and Environmental Sciences

One of the most important functions of environmental monitoring is the detection of change. This can be the delineation of deteriorating circumstances or the identification of the success of remedial measures. The design of effective monitoring of change (and hence the optimisation of resources devoted to monitoring) relies on appropriate replication - knowing how many samples are required. Lack of information on the variance of the measured parameter is often a barrier to determining the optimum sampling strategy. An important new information resource on within-site variance of the concentrations of over 60 trace substances in wastewater treatment works effluents has …

Quantified Moorland Vegetation And Assessment Of The Role Of Burning Over The Past Five Millennia, Ralph M. Fyfe, Havananda Ombashi, Heather J. Davies, Katie Head

School of Geography, Earth and Environmental Sciences

© 2017 International Association for Vegetation Science. Aims: To apply the Landscape Reconstruction Algorithm (LRA) to pollen count data from multiple sites to estimate local vegetation abundance and compare with charcoal-derived records of burning. Location: Exmoor, southwest England, UK. Methods: Pollen count data from 16 sites were transformed to estimates of distance-weighted vegetation abundance using the LRA (REVEALS and LOVE models), correcting for bias in pollen production and dispersal. Charcoal concentration data from six sites were normalized using Box-Cox transformation to produce z-scores. Moving-window correlation was undertaken to compare pollen percentage values for key taxa (Calluna, Poaceae) and localized burning. …

A Multi-Technique Experimental And Modelling Study Of The Porous Structure Of Ig-110 And Ig-430 Nuclear Graphite, Katie L. Jones, Giuliano M. Laudone, G. Peter Matthews

School of Geography, Earth and Environmental Sciences

In nuclear graphite, the wide range of void sizes precludes a full characterisation of pore volume by means of a single technique. A novel multi-technique approach, consisting of pycnometry, low pressure gas adsorption and mercury porosimetry is presented. The approach is validated for two nuclear-grade graphites designed for use in Generation IV nuclear reactors, namely IG-110 and IG-430. Damage and deformation caused to the structure of the graphite by mercury intrusion is estimated by consecutive intrusion experiments. The damage is assumed to be caused by the highest applied pressures of mercury. It is compensated by substituting that part of the …

Community Resilience In Rural China: The Case Of Hu Village, Sichuan Province, G Wilson, Z Hu, S Rahman

School of Geography, Earth and Environmental Sciences

Building on conceptual frameworks to assess community resilience developed by Emery and Flora (2006) and Kelly et al. (2015), this study analyses the resilience of Hu village (Sichuan, China). The resilience of the village is assessed in the face of multiple and complex slow- and fast onset anthropogenic disturbances, especially the impacts of globalisation and modernisation, which have substantially transformed Chinese society. Hu village is typical for a rural community in transition affected by industrialisation, deagrarianisation, counter-urbanisation and changing stakeholder expectations and opportunities. This has been accompanied by agricultural depopulation, outmigration, increasing non-farm employment, declining agricultural incomes, and associated social …

Partial Replacement Of Cement For Waste Aggregates In Concrete Coastal And Marine Infrastructure: A Foundation For Ecological Enhancement?, Ryan S. Mcmanus, Nicholas Archibald, Sean Comber, Antony M. Knights, Richard C. Thompson, Louise B. Firth

School of Biological and Marine Sciences

The effects of climate change and an expanding human population are driving the need for the expansion of coastal and marine infrastructure (CMI), the development of which is introducing hard substrate into the marine environment on a previously unseen scale. Whilst the majority of previous research has focussed on how physical features affect intertidal macrobiotic communities, this study considered the effects of differences in the chemical composition of concrete on subtidal biofilm and macrobiotic communities. Two commonly used cement replacements, pulverised fly ash (PFA) and ground granulated blast-furnace slag (GGBS), were used in a combination of proportions to assess how …

The Infrastructure-Extractives-Resource Governance Complex In The Pan-Amazon: Roll Backs And Contestations, Denise Humphreys Bebbington, Ricardo Verdum, Cesar Gamboa, Anthony Bebbington

Sustainability and Social Justice

Large-scale access and energy infrastructure projects, together with expanding investments in natural resource extraction, pose significant challenges to biodiversity conservation, forest cover, and the defence of forest peoples' rights and livelihoods across the wider Amazon region. Following a period in which safeguards and forest dwellers' territorial rights were strengthened under more permissive political opportunity structures, the current period has been characterized by efforts to weaken these protections and to facilitate large-scale private investment in previously protected lands. We describe these investment-based threats to forests and rights, and the nature of regulatory rollbacks in the region. We then discuss some of …

Williams, Peter B. Woodbury, Chris Zganjar, Marci Baranski, Patricia Elias, Richard A. Houghton

Geography

Limiting climate warming to <2°C requires increased mitigation efforts, including land stewardship, whose potential in the United States is poorly understood. We quantified the potential of natural climate solutions (NCS)-21 conservation, restoration, and improved land management interventions on natural and agricultural lands-to increase carbon storage and avoid greenhouse gas emissions in the United States. We found a maximum potential of 1.2 (0.9 to 1.6) Pg CO2e year−1, the equivalent of 21% of current net annual emissions of the United States. At current carbon market prices (USD 10 per Mg CO2e), 299 Tg CO2e year−1 could be achieved. NCS would also provide air and water filtration, flood control, soil health, wildlife habitat, and climate resilience benefits.

Homogenization Of Plant Diversity, Composition, And Structure In North American Urban Yards:, William D. Pearse, Jeannine Cavender-Bares, Sarah E. Hobbie, Meghan L.

Pataki, Benjamin L. Ruddell, Meredith K. Steele, Tara L.E. Trammell

Geography

Urban ecosystems are widely hypothesized to be more ecologically homogeneous than natural ecosystems. We argue that urban plant communities assemble from a complex mix of horticultural and regional species pools, and evaluate the homogenization hypothesis by comparing cultivated and spontaneously occurring urban vegetation to natural area vegetation across seven major U.S. cities. There was limited support for homogenization of urban diversity, as the cultivated and spontaneous yard flora had greater numbers of species than natural areas, and cultivated phylogenetic diversity was also greater. However, urban yards showed evidence of homogenization of composition and structure. Yards were compositionally more similar across …

Geography

Long-term, accurate observations of atmospheric phenomena are essential for a myriad of applications, including historic and future climate assessments, resource management, and infrastructure planning. In Hawai'i, climate data are available from individual researchers, local, State, and Federal agencies, and from large electronic repositories such as the National Centers for Environmental Information (NCEI). Researchers attempting to make use of available data are faced with a series of challenges that include: (1) identifying potential data sources; (2) acquiring data; (3) establishing data quality assurance and quality control (QA/QC) protocols; and (4) implementing robust gap filling techniques. This paper addresses these challenges by …

Resource Extraction And Infrastructure Threaten Forest Cover And Community Rights, Anthony J. Bebbington, Denise Humphreys Bebbington, Laura Aileen Sauls, John Rogan, Sumali Agrawal, César Gamboa, Aviva Imhof, Kimberly Johnson, Herman Rosa, Antoinette Royo, Tessa Toumbourou, Ricardo Verdum

Geography

Mineral and hydrocarbon extraction and infrastructure are increasingly significant drivers of forest loss, greenhouse gas emissions, and threats to the rights of forest communities in forested areas of Amazonia, Indonesia, and Mesoamerica. Projected investments in these sectors suggest that future threats to forests and rights are substantial, particularly because resource extraction and infrastructure reinforce each other and enable population movements and agricultural expansion further into the forest. In each region, governments have made framework policy commitments to national and cross-border infrastructure integration, increased energy production, and growth strategies based on further exploitation of natural resources. This reflects political settlements among …

The Gundlach Collection : A Study Of Projectile Points From The Albeni Falls Reservoir, Jeffrey Cortlund Johnson

EWU Masters Thesis Collection

A formerly private collection of projectile points belonging to the Kalispel Tribe of Indians Cultural Resources Program provides stylistic, temporal, and geographic information for sites in the Albeni Falls Reservoir, Idaho. Specifically, there are 462 artifacts from 24 sites based on information derived from the collector’s and tribal archaeologist’s notes. Depositional information is unknown and artifacts are as surface finds. Analyses performed in this study include the morphological and technological dimensions of style, geographic and temporal distribution of artifacts by site, comparative results of obsidian x-ray fluorescence, and high-resolution photography. The results demonstrate the collection as a pragmatic dataset yielding …

Camping For The Need Of Speed: An Analysis Of The Motives Of Nascar Fanatics To Rv Camp At Racing Events, Dylan P. Williams, Cheryl R. Rode, Mark A. Slavich

Global Sport Business Journal

Traveling to attend sporting events has become an increasingly popular activity in recent years. Prior investigations of sport tourism found individuals travel primarily because of the social aspect of the experience while the location of the event was relatively unimportant. Although traveling via recreational vehicles (RVs) gained in popularity, little research examined RV tourism in the context of NASCAR. Therefore, this study investigated the motives of RV tailgaters to Talladega Superspeedway and the role of destination image in individuals’ decision to travel. Results displayed RV tailgaters to Talladega were most motivated by the event’s destination image. In addition, race attractiveness …

Evidence Of Racial And Geographic Disparities In The Use Of Medicare Observation Stays And Subsequent Patient Outcomes Relative To Short-Stay Hospitalizations, Brad Wright, Xuan Zhang, Momotazur Rahman, Mahshid Abir, Padmaja Ayyagari, Keith E. Kocher

Research Collection School Of Economics

To examine racial and geographic disparities in the use of-and outcomes associated with-Medicare observation stays versus short-stay hospitalizations.\nWe used 2007-2010 fee-for-service Medicare claims, including 3,555,994 observation and short-stay hospitalizations for individuals over age 65. We estimated linear probability models with hospital fixed effects to identify within-facility disparities in observation stay use, and estimated in-hospital mortality, and 30- and 90-day post-discharge mortality, return ED visits, and hospital readmissions as a function of placement in observation using linear probability models, propensity-score matching, and interaction terms.\nWe identified racial and geographic disparities in the likelihood of observation stay use within hospitals (blacks 3.9 percentage …

Spatiotemporal Evolution Of Land Subsidence In The Beijing Plain 2003–2015 Using Persistent Scatterer Interferometry (Psi) With Multi-Source Sar Data, Chaodong Zhou, Huili Gong, Youquan Zhang, Timothy A. Warner, Cong Wang

Faculty & Staff Scholarship

Land subsidence is one of the most important geological hazards in Beijing, China, and its scope and magnitude have been growing rapidly over the past few decades, mainly due to long-term groundwater withdrawal. Interferometric Synthetic Aperture Radar (InSAR) has been used to monitor the deformation in Beijing, but there is a lack of analysis of the long-term spatiotemporal evolution of land subsidence. This study focused on detecting and characterizing spatiotemporal changes in subsidence in the Beijing Plain by using Persistent Scatterer Interferometry (PSI) and geographic spatial analysis. Land subsidence during 2003–2015 was monitored by using ENVISAT ASAR (2003–2010), RADARSAT-2 (2011–2015) …

Reducing Uncertainties In Applying Remotely Sensed Land Use And Land Cover Maps In Land-Atmosphere Interaction: Identifying Change In Space And Time, Yaqian He, Timothy A. Warner, Brenden E. Mcneil, Eungul Lee

Faculty & Staff Scholarship

Land use and land cover (LULC) data are a central component of most land-atmosphere interaction studies, but there are two common and highly problematic scale mismatches between LULC and climate data. First, in the spatial domain, researchers rarely consider the impact of scaling up fine-scale LULC data to match coarse-scale climate datasets. Second, in the temporal domain, climate data typically have sub-daily, daily, monthly, or annual resolution, but LULC datasets often have much coarser (e.g., decadal) resolution. We first explored the effect of three spatial scaling methods on correlations among LULC data and a land surface climatic variable, latent heat …

Past And Future Drought In Mongolia, Amy Hessl, Kevin J. Anchukaitis, Casey Jelsema, Benjamin Cook, Oyunsanaa Byambasuren, Caroline Leland, Baatarbileg Nachin, Neil Pederson, Hanqin Tian, Laia Andreu Hayles

Faculty & Staff Scholarship

The severity of recent droughts in semiarid regions is increasingly attributed to anthropogenic climate change, but it is unclear whether these moisture anomalies exceed those of the past and how past variability compares to future projections. On the Mongolian Plateau, a recent decade-long drought that exceeded the variability in the instrumental record was associated with economic, social, and environmental change. We evaluate this drought using an annual reconstruction of the Palmer Drought Severity Index (PDSI) spanning the last 2060 years in concert with simulations of past and future drought through the year 2100 CE.We show that although the most recent …

Improved Kerogen Models For Determining Thermal Maturity And Hydrocarbon Potential Of Shale, Vikas Agrawal, Shikha Sharma

Faculty & Staff Scholarship

Kerogen is the insoluble component of organic-rich shales that controls the type and amount of

hydrocarbons generated in conventional and unconventional reservoirs. Significant progress has

recently been made in developing structural models of kerogen. However, there is still a large gap in understanding the evolution of the molecular components of kerogen with thermal maturation and their hydrocarbon (HC) generative potential. Here, we determine the variations in different molecular fragments of kerogen from a Marcellus Shale maturity series (with VRo ranging from 0.8 to 3) using quantitative 13C MultiCP/MAS NMR and MultiCP NMR/DD (dipolar dephasing). These molecular variations provide insight into …

Essays On Measuring Dynamic Community Responses To Environmental Events, Patrick Prendergast

Open Access Dissertations

One of the things that makes economics such an interesting social science sub-field to study is the analysis of unintended or unforeseen consequences. In order for policies to be efficient and equitable, it is important to first understand how endogenous policy decisions and exogenous events can affect communities either directly or indirectly. In this dissertation research, I examine how communities react to discrete environmental events over time. I do so in the context of tropical storm and hurricane activity in U.S. counties and media markets as well as land conservation spending decisions in Massachusetts and New Jersey municipalities. Using micro-level …

Understanding The Connection Between The Hydro-Climatic Extremes And Diarrheal Diseases Over Bengal Delta: The Vulnerability Assessment Of Past, Present And Future, Mohammad Alfi Hasan

Open Access Dissertations

Living in the age of space exploration and nanotechnology, the significant portion of human population still have threatened by diarrheal diseases throughout the globe. Being a major contributor of the global mortality, the diarrheal diseases account for an estimated 3.1% of the total burden of disease in terms of Disability-Adjusted Life Year (DALY) where cholera and rotavirus diarrhea comprise more than two-thirds of the diarrheal morbidity in developing countries of South Asia.

Alongside with many more challenges like climate change or civil war, the capability to resolve the diarrheal disease burden in developing countries remains questionable. As the primary reasons …

The Bearish Bankruptcy, Diane L. Dick

Georgia Law Review

Modern bankruptcy practice under Chapter 11
presumptively excludes the large and publicly-traded
corporate debtor's shareholders from the negotiation
table based on a longstanding assumption that they
have no economic interest to protect because most
bankrupt companies are insolvent. But bankruptcy
practice overlooks a shareholder's most important
economic interest: the right to enjoy the reorganized
firm's unlimited upside potential after all creditor
claims are satisfied. This interest, which is essentially
an option right, is totally ignored in the debtor's
hypothetical liquidation analysis. In a similar way,
the debtor's upside potential is not fully captured by
prevailing enterprise valuation techniques.
Of course, …
