National Newspaper Analysis of the Press Coverage of Jesse Jackson\u27s 1984 Presidential Campaign: The Confirmation of the Candidate
Jesse Jackson\u27s 1984 and 1988 presidential campaigns have motivated thousands of citizens throughout America to take a more active role in politics. The 1984 campaign witnessed many previously unregistered Americans actively participating in Jackson\u27s call to join the Rainbow Coalition. Four years later, Jackson once again hit a responsive chord within the American electorate, broadening his support base in his second run for the White House. His vibrant campaigns presented challenges not only to the American system of government, but also to accepted journalistic traditions in campaign reporting. Specifically, the dilemma has been a difficult one for journalists responsible for campaign coverage. How much coverage should a reporter give to Jesse Jackson\u27s campaign? Should he be treated like an Alan Cranston or Gary Hart in 1984, or a Paul Simon or Albert Gore in 1988? Or does the historical impact of his being the first black candidate to make a serious bid for the presidency warrant a different approach to press coverage? Highlighting this dilemma in the 1984 campaign, Dates and Gandy note: Jackson\u27s candidacy was a challenge for the press because on the one hand journalistic traditions would dictate that the ideological orientation of the media organization would constrain its coverage to be consistent with longstanding editorial practice.[1
SYNCHRONOUS CMC, WORKING MEMORY, AND L2 ORAL PROFICIENCY DEVELOPMENT
Recently a number of quasi-experimental studies have investigated the potential of a cross-modality transfer of second language competency between real-time, conversational exchange via text and speech (Abrams, 2003; Beauvious, 1998; Kost, 2004; Payne & Whitney, 2002). Payne and Whitney employed Levelt's (1989) model of language production and concepts from working memory as a rationale for a hypothesized connection between synchronous computer-mediated communication (SCMC) and second language (L2) speech and as a basis for predicting the differential contributions of SCMC to the L2 oral proficiency development.This study extends the psycholinguistic framework reported in Payne and Whitney (2002) with discourse and corpus analytic techniques to explore how individual differences in working memory capacity may affect the frequency of repetition and other patterns of language use in chatroom discourse. Working memory capacity was measured by a reading span and nonword repetition test. Oral proficiency was measured with a speaking task that solicited a 5-minute speech sample and was scored based on a holistic scale. The data collected from 20 chat sessions were analyzed for occurrences of repetition and relexicalization, as well as language output measures. Findings suggest a connection between working memory and language output as measured in this study

Classification of Aquifers
This dissertation contains three papers describing an approach to classifying aquifers and groundwater systems. The three papers bring together the development of a basin scale groundwater classification system that integrates the literature, data gathering, and data analysis and testing. The classification system is a comprehensive method designed to improve interdisciplinary communication and standardize how groundwater systems are compared in watersheds across in the west and potentially beyond.
Aquifers and groundwater systems can be classified using a variety of independent methods to characterize geologic and hydraulic properties, the degree of connection with surface water, and geochemical conditions. In light of a growing global demand for water associated with population growth, land development, and the expected effects of climate change, a standardized approach for classifying groundwater systems at the watershed scale is needed. To this end, a comprehensive classification system is developed that combines recognized methods and new approaches into one system. The purpose of this approach is to provide groundwater professionals, policy makers, and watershed managers with a widely applicable classification system that reduces sometimes cumbersome complex groundwater databases and analyses to straightforward graphical representations. The proposed classification system uses basin geology, aquifer productivity, threats and impacts posed by humans, water quality, and the degree of groundwater/surface water exchange as classification criteria. The approach is based on literature values, reference databases, and basic hydrologic and hydrogeologic principles. The proposed classification system treats data set completeness as a variable and includes a tiered assessment protocol that depends on the quality and quantity of data. In addition, it assembles and catalogs groundwater information using a consistent set of nomenclature. It is designed to analyze and display results using Geographical Information System (GIS) mapping tools, while standardizing descriptions of groundwater conditions and to support resource managers as they make land use decisions at the watershed scale.
Together, the three papers describe a method for comparing and contrasting aquifer properties and systems needed by watershed managers. It is argued that the proposed methodology is needed to assist managers and planner in understanding the role of aquifers in watersheds as well as for the broad multi-basin comparison of aquifer data . The classification method does not replace current standard practices traditionally used to assess or characterize aquifers and groundwater systems. However, it does provide a standard methodology by which existing and new hydrogeologic data can be organized, easily communicated, and broadly compared on a watershed scale of 1:100,000 to 1:250,000. It is believed this classification system will promote an improved technical understanding between groundwater professionals and natural resource managers. Three appendices are included in this dissertation. The appendices provide supporting information for the three papers and results for four case studies
Investigating the Heat Release from a Single-Cylinder Diesel Engine
This project develops a dynamic measuring processes and filtering technique to acquire accurate engine thermodynamic data using LabVIEW. A single-cylinder Kohler diesel engine (model KD440) is instrumented with an in-cylinder pressure monitoring transducer to obtain cylinder pressure and volume data as a function of crank angle position. From this data, several calculations will be made using thermal analysis to understand the engine\u27s performance. An additional objective of the project is to increase the efficiency of the engine\u27s air intake system by modifying the current configuration. We show that the monitoring software accurately measures real-time engine efficiency and combustion dynamics enabling future fuel and combustion research at USM
Overview of the Flathead Lake Voluntary Nutrient Reduction Strategy (VNRS)
If you ask Montanans which five Montana lakes are the most important or valuable, invariably Flathead Lake is in the top three picks. The lake\u27s size, beauty, recreation benefits, and excellent water quality increase local real estate values and make it a popular destination. However, few Montanans know that Flathead Lake currently does not meet State water quality standards (ARM 17.30.637 (1)(e)General Prohibitions), and is undergoing the eutrophication process at an accelerated rate. Excess nutrients (phosphorus and nitrogen) stimulate algal blooms and serious oxygen depletion of the deep waters. Extensive lake and stream water quality monitoring document that nonpoint source pollution is degrading water quality, interfering with beneficial uses, and causing violation of water quality standards. As a result, Flathead Lake is included on the Clean Water Act’s Section 303(d) list of water-quality-impaired waterbodies, and is a high priority for developing a water quality restoration plan (called a Total Maximum Daily Load or TMDL). Such a plan is close to completion.
Probable sources of water quality impairment include atmospheric deposition, domestic wastewater lagoons, flow regulation/modification, municipal point sources, on-site wastewater treatment systems (septic tanks), urban sprawl, overland runoff, agriculture, silvaculture, and an upstream impoundment. Only 2 percent of the nutrient load in Flathead Lake is estimated to come from point sources. The vast majority of nutrients come from natural sources or human-caused nonpoint source pollution. To address nonpoint source pollution, the Flathead Basin Commission (FBC) developed the Voluntary Nutrient Reduction Strategy (VNRS), and linked it to the TMDL process. The goal of the VNRS is to achieve the 1978 lake primary productivity level of 80 grams carbon/m2/year. This level is expected to yield water quality that meets water quality standards and supports beneficial uses (including swimming and aquatic life support). To meet the target primary productivity, the FBC determined that nitrogen (including nitrate plus nitrite) and phosphorus loading must be reduced by 15 percent basin wide. Six principal components for successful implementation of the ongoing VNRS/TMDL program include:
(1) coordination and planning, (2) grant funding & contributions (3) partnerships and public outreach, (4) participation of watershed groups, (5) identification of opportunities, and (6) monitoring. History, implementation and achievements of the Flathead Basin VNRS/TMDL are described in this paper
Examination of Surface Deposits on Oldbury Reactor Core Graphite to Determine the Concentration and Distribution of <sup>14</sup>C
Pile Grade A graphite was used as a moderator and reflector material in the first generation of UK Magnox nuclear power reactors. As all of these reactors are now shut down there is a need to examine the concentration and distribution of long lived radioisotopes, such as 14C, to aid in understanding their behaviour in a geological disposal facility. A selection of irradiated graphite samples from Oldbury reactor one were examined where it was observed that Raman spectroscopy can distinguish between underlying graphite and a surface deposit found on exposed channel wall surfaces. The concentration of 14C in this deposit was examined by sequentially oxidising the graphite samples in air at low temperatures (450°C and 600°C) to remove the deposit and then the underlying graphite. The gases produced were captured in a series of bubbler solutions that were analysed using liquid scintillation counting. It was observed that the surface deposit was relatively enriched with 14C, with samples originating lower in the reactor exhibiting a higher concentration of 14C. Oxidation at 600°C showed that the remaining graphite material consisted of two fractions of 14C, a surface associated fraction and a graphite lattice associated fraction. The results presented correlate well with previous studies on irradiated graphite that suggest there are up to three fractions of 14C; a readily releasable fraction (corresponding to that removed by oxidation at 450°C in this study), a slowly releasable fraction (removed early at 600°C in this study), and an unreleasable fraction (removed later at 600°C in this study)
