Down The Rabbit Hole: Identifying Physical Controls On Sinkhole Formation In The Uk, Tamsin Green

Sinkhole Conference 2015

Heavy precipitation in the UK in February 2014 induced ground subsidence and consequently a rapid increase in the frequency of sinkhole occurrences. These new sinkhole collapses emphasise the need to further analyse the causes of the increased occurrence by investigating the relative importance of various surficial factors. Malham and the Mendips are two areas of particular interest, since both are underlain by limestone bedrock and are susceptible to subsidence. This is due to limestone being primarily permeable in joints, and so it dissolves to form an extensive network of karstic caves. It was therefore useful to compare two sites of …

Spatiotemporal Response Of Cvoc Contamination And Remedial Actions In Eogenetic Karst Aquifers, Ingrid Y. Padilla, Vilda L. Rivera, Celys Irizarry

Sinkhole Conference 2015

The northern karst region of Puerto Rico has a long and extensive history of toxic spills, chemical waste, and industrial solvent release into the subsurface. High potential for exposure in the region has prompted aggressive remediation measures, which have extended for over 40 years. Of particular concern is contamination with chlorinated volatile organic compounds (CVOCs) because of their ubiquitous presence and potential health impacts. This work evaluates historical groundwater quality data to assess the spatiotemporal distribution of CVOC contamination in the karst aquifer system of northern Puerto Rico, and its response to remedial action in two superfund sites contaminated with …

Tracking Of Karst Contamination Using Alternative Monitoring Technologies: Hidden River Cave Kentucky, Caren Raedts, Christopher Smart

Sinkhole Conference 2015

Karst groundwater contamination presents great challenges for efficient monitoring because of rapid, discrete transport and the diversity of contaminants. Here a low cost approach is described and applied to Hidden River Cave, Kentucky, where a long history of contamination has been experienced. Local knowledge was acquired through informal interviews and coupled with observations of contaminant residues, faunal distributions and fluorescence spectra in the cave. The resulting patterns were interpreted using Google Earth and Street View to identify specific contaminant sources in the affected sub-catchment of the cave. Despite success in matching contaminant sources with the contamination history and pattern, the …

Framing The Mh17 Disaster – More Heat Than Light?, Simon A. Bennett

International Journal of Aviation, Aeronautics, and Aerospace

Despite the reductionist analyses produced by politicians and the Fourth Estate, the loss of Malaysia Airlines Flight MH17 was a systems accident – a product of the interactions between the actants that compose the commercial aviation system network-space. As an antidote to reductionism’s ‘fundamental attribution error’, this paper presents a systems-thinking-informed analysis of the MH17 disaster. To this end it draws on Actor-Network Theory and the work of Reason, Toft, Dekker, Hollnagel and other systems-thinking advocates. Whether intentional or not, politicians’ reductionist analyses generated political capital. European Union and American finger-pointing distracted from aviation authorities’ and airlines’ ill-advised routing policies. …

The Role Of Self-Awareness In Developing Global Competence: A Qualitative Multi-Case Study, Stacy D. Shipman

Graduate Theses, Dissertations, and Capstones

The current era of globalization and unprecedented global migration is creating the need for schools to educate students for global competence (GC). Multiple researchers (Boix Mansilla & Jackson, 2011; Hunter, 2004; Hunter et al., 2006; Morales & Ogden, 2013) suggest that self-awareness is the core dimension of GC, but about which very little is known. This paper considers the demonstrations of self-awareness in the development of GC. Using Kim's (2008) Intercultural Personhood Theory and the specific components of personal and social communication processes, self-awareness was investigated in East African immigrants. Findings suggest that the construct of self-awareness dimensionalizes differently for …

A Phenomic Scan Of The Norfolk Island Genetic Isolate Identifies A Major Pleiotropic Effect Locus Associated With Metabolic And Renal Disorder Markers, Miles C. Benton, Rodney A. Lea, Donia Macartney-Coxson, Michelle Hanna, David A. Eccles, Melanie A. Carless, Claire Bellis, Harald H. H. Goring, Joanne E. Curran, John Blangero

School of Medicine Publications

Multiphenotype genome-wide association studies (GWAS) may reveal pleiotropic genes, which would remain undetected using single phenotype analyses. Analysis of large pedigrees offers the added advantage of more accurately assessing trait heritability, which can help prioritise genetically influenced phenotypes for GWAS analysis. In this study we performed a principal component analysis (PCA), heritability (h2) estimation and pedigree-based GWAS of 37 cardiovascular disease -related phenotypes in 330 related individuals forming a large pedigree from the Norfolk Island genetic isolate. PCA revealed 13 components explaining >75% of the total variance. Nine components yielded statistically significant h2 values ranging from 0.22 to 0.54 (P<0.05). The most heritable component was loaded with 7 phenotypic measures reflecting metabolic and renal dysfunction. A GWAS of this composite phenotype revealed statistically significant associations for 3 adjacent SNPs on chromosome 1p22.2 (P<1x10-8). These SNPs form a 42kb haplotype block and explain 11% of the genetic variance for this renal function phenotype. Replication analysis of the tagging SNP (rs1396315) in an independent US cohort supports the association (P = 0.000011). Blood transcript analysis showed 35 genes were associated with rs1396315 (P<0.05). Gene set enrichment analysis of these genes revealed the most enriched pathway was purine metabolism (P = 0.0015). Overall, our findings provide convincing evidence for a major pleiotropic effect locus on chromosome 1p22.2 influencing risk of renal dysfunction via purine metabolism pathways in the Norfolk Island population. Further studies are now warranted to interrogate the functional relevance of this locus in terms of renal pathology and cardiovascular disease risk.

Numerical Modelling Of The Wave Propagation Close To The Sacalin Island In The Black Sea, Liliana Rusu, Dorin Butunoiu

Journal of Marine Science and Technology–Taiwan

The target area of the present work is the nearshore neighbouring the Sacalin Island in the Black Sea, right off the Danube Delta and close to the Saint George branch of the Danube River. Being a newly formed island, this is a very special coastal environment. Moreover, because it has a great variety of rare fauna, the area was declared as an ecological reserve. A multilevel wave modelling system, based on the Simulating Waves Nearshore (SWAN) spectral model, was focused on the target area. In the final computational domain, with the highest resolution in the geographical space, the effect of …

Characterisation, Quantity And Sorptive Properties Of Microplastics Extracted From Cosmetics, Imogen E. Napper, Adil Bakir, Steven J. Rowland, Richard C. Thompson

School of Geography, Earth and Environmental Sciences

Cosmetic products, such as facial scrubs, have been identified as potentially important primary sources of microplastics to the marine environment. This study characterises, quantifies and then investigates the sorptive properties of plastic microbeads that are used as exfoliants in cosmetics. Polyethylene microbeads were extracted from several products, and shown to have a wide size range (mean diameters between 164 and 327μm). We estimated that between 4594 and 94,500 microbeads could be released in a single use. To examine the potential for microbeads to accumulate and transport chemicals they were exposed to a binary mixture of ³H-phenanthrene and ¹⁴C-DDT …

The Trial Of Calcium And Vitamin D For The Prevention Of Colorectal Adenomas, John A. Baron, Elizabeth L. Barry, Leila A. Mott, Judy R. Rees

Dartmouth Scholarship

BACKGROUND Epidemiologic and preclinical data suggest that higher intake and serum levels of vitamin D and higher intake of calcium reduce the risk of colorectal neoplasia. To further study the chemopreventive potential of these nutrients, we conducted a randomized, double-blind, placebo-controlled trial of supplementation with vitamin D, calcium, or both for the prevention of colorectal adenomas. METHODS We recruited patients with recently diagnosed adenomas and no known colorectal polyps remaining after complete colonoscopy. We randomly assigned 2259 participants to receive daily vitamin D3 (1000 IU), calcium as carbonate (1200 mg), both, or neither in a partial 2Å~2 factorial design. Women …

Racial Disparities In Intravenous Recombinant Tissue Plasminogen Activator Use Persist At Primary Stroke Centers., Hugo J. Aparicio, Brendan G. Carr, Scott E. Kasner, Michael J. Kallan, Karen C. Albright, Dawn O. Kleindorfer, Michael T. Mullen

Department of Emergency Medicine Faculty Papers

BACKGROUND: Primary stroke centers (PSCs) utilize more recombinant tissue plasminogen activator (rt-PA) than non-PSCs. The impact of PSCs on racial disparities in rt-PA use is unknown.

METHODS AND RESULTS: We used data from the Nationwide Inpatient Sample from 2004 to 2010, limited to states that publicly reported hospital identity and race. Hospitals certified as PSCs by The Joint Commission were identified. Adults with a diagnosis of ischemic stroke were analyzed. Rt-PA use was defined by the International Classification of Diseases, 9th Revision procedure code 99.10. Discharges (304 152 patients) from 26 states met eligibility criteria, and of these 71.5% were …

‘Capitalism A Nuh’ Wi Frien’. The Formatting Of Farming Into An Asset, From Financial Speculation To International Aid, Luigi Russi, Tomaso Ferrando

Catalyst: A Social Justice Forum

This paper deciphers the formatting of farming into an asset by tracking the modalities by which financial calculation is enabled across different sites of agency.

The first focus of our analysis are commodity futures markets, which have witnessed a double spike in prices in 2008 and in 2012. In the paper, we look at these hikes as the outcome of endogenous dynamics, caused by the changing makeup of market participants after 2000, which turned futures markets into resources for hedging commodity index-linked derivative products.

We subsequently analyse the increasing reliance on financial actors placed by public development agencies that channel …

Will Remote Sensing Shape The Next Generation Of Species Distribution Models?, Kate S. He, Bethany A. Bradley, Anna F. Cord, Duccio Rocchini, Mao‐Ning Tuanmu, Sebastian Schmidtlein, Woody Turner, Martin Wegmann, Nathalie Pettorelli

Faculty & Staff Research and Creative Activity

Two prominent limitations of species distribution models (SDMs) are spatial biases in existing occurrence data and a lack of spatially explicit predictor variables to fully capture habitat characteristics of species. Can existing and emerging remote sensing technologies meet these challenges and improve future SDMs? We believe so. Novel products derived from multispectral and hyperspectral sensors, as well as future Light Detection and Ranging (LiDAR) and RADAR missions, may play a key role in improving model performance. In this perspective piece, we demonstrate how modern sensors onboard satellites, planes and unmanned aerial vehicles are revolutionizing the way we can detect and …
