Phylogeographic Analyses Of Obligate And Facultative Cave Crayfish Species On The Cumberland Plateau Of The Southern Appalachians, Jennifer Elizabeth Buhay Jul 2006

Phylogeographic Analyses Of Obligate And Facultative Cave Crayfish Species On The Cumberland Plateau Of The Southern Appalachians, Jennifer Elizabeth Buhay

Theses and Dissertations

Cave systems and their unique biota are widely viewed as highly endangered, yet very little is known about basic life history, ecology, distributions, habitat requirements, and evolutionary relationships of subterranean species. The crux of the problem in cave studies is the assumption that traditionally defined morpho-species represent distinct evolutionary lineages. Convergence is exhibited in the morphologies of many animal groups, vertebrate and invertebrate, which leads to confusion in diagnosing species' boundaries, geographic distributions, gene flow routes, and imperilment. This dissertation research includes phylogeographic analyses of freshwater cave-dwelling crayfishes in the Southern Appalachians, a global hotspot of subterranean biodiversity. By examining …

Psychometrically Equivalent Bisyllabic Words For Speech Reception Threshold Testing In Arabic, Elisha Rose Ratcliff Jul 2006

Psychometrically Equivalent Bisyllabic Words For Speech Reception Threshold Testing In Arabic, Elisha Rose Ratcliff

Theses and Dissertations

The use of speech audiometry is essential in audiological testing. One of the most important elements of speech audiometry is speech reception threshold. To provide services for the growing population of non-English speaking people, audiologists need speech audiometry materials in a variety of languages. The purpose of this study was to develop, digitally record, evaluate, and equate Arabic bisyllabic words for use in testing speech reception threshold. Ninety frequently used bisyllabic words were digitally recorded by a male talker of standard Arabic. These words were presented to 20 normally hearing subjects in 2 dB increments at intensity levels ranging from …

The Familiar Foreign Country: Reading Mexico In Cormac Mccarthy, Jack Kerouac, And Katherine Anne Porter, Rachel Mae Ligairi Jul 2006

The Familiar Foreign Country: Reading Mexico In Cormac Mccarthy, Jack Kerouac, And Katherine Anne Porter, Rachel Mae Ligairi

Theses and Dissertations

My thesis examines the discourse of Mexico in the works of three twentieth-century American authors-Cormac McCarthy, Jack Kerouac, and Katherine Anne Porter-in order to analyze representations of Otherness in modernism and postmodernism. I seek to destabilize the dividing line between these periods as well as to show how representation in postmodernity has become more problematic due in large part to the proliferation of consumer culture. Though the Mexico that McCarthy employs in Blood Meridian and the Border Trilogy (All the Pretty Horses, The Crossing, and Cities of the Plain) escapes many stereotypes, his Mexico is merely a staging ground that …

The Use Of Inductive And Deductive Reasoning To Model Snowmelt Runoff From Northern Mountain Catchments, P. F. Dornes, J. W. Pomeroy, A. Pietroniro, S. K. Careyc, W. L. Quinton Jul 2006

The Use Of Inductive And Deductive Reasoning To Model Snowmelt Runoff From Northern Mountain Catchments, P. F. Dornes, J. W. Pomeroy, A. Pietroniro, S. K. Careyc, W. L. Quinton

International Congress on Environmental Modelling and Software

Reliable hydrological modeling at small to medium scales is very difficult. At these scale, models require incorporation of both detailed process understanding and inputs along with information gained from observations of basin-wide streamflow phenomenon; essentially a combination of deductive and inductive approaches. At Granger Creek, part of the Wolf Creek Research Basin in the mountains of the Yukon Territory, Canada, sparse and shrub tundra cover the basin and soils are frozen at the time of snowmelt. Wind redistributes snow to north facing slopes and shrub tundra areas, while spring melt rates are much higher on south facing slopes due to …

Autonomous Flood Sensorweb: Multi-Sensor Rapid Response And Early Flood Detection, Felipe Ip, J. M. Dohm, V. R. Baker, R. Brakenridge, A. G. Davies, Steve Chien

International Congress on Environmental Modelling and Software

Extreme floods have been reported to be more frequent partly due to global warming. As such, the necessity for timely detection and mapping of floods is increasingly important in order to protect lives and livelihoods. Floods affect large regions of the Earth and cannot be reliably predicted. Hydrological data from in-situ sensors are sparse and cannot map the full extent of flooding. The use of satellite-based information for assessing floods is not new. However, the problem with satellite remote sensing historically has been both the large areas affected and obtaining timely ground-based reception of satellite data. The Autonomous Sciencecraft Experiment …

Luckai, Jinxun Liu, Shuguang Liu, P. A. Arp, C. -F Zhang, Alexander Komarov, Pavel Grabarnik, M. Wattenbach, C. Peng, Jianfeng Sun, Thomas White

International Congress on Environmental Modelling and Software

Many process-based models on carbon (C) and nitrogen (N) cycles have been developed for northern forest ecosystems. These models are widely used to evaluate the long-term decisions in forest management dealing with effects like particulate pollution, productivity and climate change. Regarding climate change, one of the key questions that have sensitive political implications is whether northern forests will sequester atmospheric C or not. Whilst many process-based models have been tested for accuracy by evaluating or validating against observed data, few have dealt with the complexity of the incorporated procedures to estimate uncertainties associated with model predictions or the sensitivity of …

Environmental Policy Aid Under Uncertainty, J. Myšiak, J. D. Brown Jul 2006

Environmental Policy Aid Under Uncertainty, J. Myšiak, J. D. Brown

International Congress on Environmental Modelling and Software

Uncertainty pervades all aspects of environmental policy making. Numerous typologies and techniques have been developed to conceptualise, classify, assess (qualitatively and quantitatively), propagate, control, reduce and communicate uncertainty. Such assessments are a necessary but insufficient condition for reducing uncertainty in environmental decision making. In this paper we discuss how uncertainty is translated into decisions. Since this entails numerous value judgements and trade-offs which are sensitive to how policy problems are framed, we argue that perceptions of uncertainty cannot be viewed independently of the (quality of) the policy process that it intends to inform. Thus, uncertainty management should not be limited …

Towards Better Water Governance: Putting Integrated Water Resource Management In Place, J. Myšiak, Carlo Giupponi Jul 2006

Towards Better Water Governance: Putting Integrated Water Resource Management In Place, J. Myšiak, Carlo Giupponi

International Congress on Environmental Modelling and Software

Water is a finite, renewable, yet in certain circumstances depletable, natural resource with essential value for life. The uneven distribution of water resources, amplified by numerous conflicting water uses, constrains economic development and the wellbeing of humans. The excessive quantity of water as a result of land use and/or climate change (and thus at least partly accountable to human activities) poses additional threats. To ensure an efficient allocation and protection of water, a holistic (integrated/comprehensive) management based on the principles of the ecosystem approach was endorsed by a broad scientific and policy community. Such management was aimed at promoting pro-active, …

International Congress on Environmental Modelling and Software

The functional description of natural systems requires the representation of different classes of processes including chemical, biochemical, and physical functions, with or without their spatial representation. On the other hand, there are several cases where a realistic representation of the process dynamics needs a spatially explicit implementation of the model (eg. hydrological flows, fire propagation, pollution diffusion, etc.). In more general terms, and for different scientific fields, scaling problems and the issue of linking dynamic and spatial processes require an integrated logic and appropriate software solutions. Different tools aimed at implementing spatial modelling capability (PCRaster, SME, SimARC) have not yet …

Uncertainty Management, Spatial And Temporal Reasoning, And Validation Of Intelligent Environmental Decision Support Systems, Miquel Sànchez-Marrè, Karina Gibert, Rick Sojda, Jean-Philippe Steyer, Peter Struss, Ignasi Rodríguez-Roda

International Congress on Environmental Modelling and Software

There are inherent open problems arising when developing and running Intelligent Environmental Decision Support Systems (IEDSS). During daily operation of IEDSS several open challenge problems appear. The uncertainty of data being processed is intrinsic to the environmental system, which is being monitored by several on-line sensors and off-line data. Thus, anomalous data values at data gathering level or even uncertain reasoning process at later levels such as in diagnosis or decision support or planning can lead the environmental process to unsafe critical operation states. At diagnosis level or even at decision support level or planning level, spatial reasoning or temporal …

Structure - Fate - Relationships Of Organic Chemicals, Rainer Brüggemann, Guillermo Restrepo, Kristina Voigt

International Congress on Environmental Modelling and Software

The evaluation of the potential risk of chemicals receives again a lot of interest due to the renewed chemicals’ policy in the EU. The model package E4CHEM (Exposure Estimation for Potentially Ecotoxic Environmental Chemicals), already developed 1984-1992, is presented in this paper. This is a model which on the one side needs less information or input parameters as the often applied EUSES (European Union System for the Evaluation of Substances) and on the other side provides modules, like EXWAT (Model for the behaviour of the chemical in rivers)) and DTEST (Automatic Data Estimation), which as such are not contained in …
