Jackson Blue is a first magnitude spring in the karst terrane of northeast Florida. Previous studies have identified inorganic fertilizer as the source of high nitrate levels in the spring. Agricultural land use and karst vulnerability make Jackson Blue a good model for conservation concerns. This work offers an aggregation of studies relating to the springshed, providing a valuable tool for planning and conservation efforts in the region. An analysis of nitrate levels and other water quality parameters within the springshed did not reveal significantly different values between agricultural and forested land use areas. Confounding factors include: high transmissivity in the aquifer, interspersed land use parcels, and fertilizer application in forested areas due to commercial pine stand activity.

The problem with which this paper is concerned is that of tracing Gothic elements in the six complete novels of Shirley Jackson (1919-1965). Jackson's novels, magazine reviews of these novels, articles on Gothicism, and histories of English literature form the sources of data for this research project.

From July through November 2002, the internship which I have been engaged in at Jackson Barracks Military Museum has afforded me opportunity to gain practical experience in both the curatorial and preparatory aspects of museum operations. Jackson Barracks Military Museum is part of a larger state agency, "The Military Directorate" and its governing board is appointed in accordance with state law. Jackson Barracks Military Museum is presently being restructured to acquire certification from the U.S. Army Center of Military History Museum Division. Katz in "Museum Trusteeship: The Fiduciary Ethic Applied" The Journal of Arts Management and Law (73) writes that the museum community has been compelled to develop codes of ethics and sound practices and procedures for their board members, and museum management. This effort will bring this State Museum more in line with the requirements of the American Association of Museums for certification. I was and am pleased to have had the opportunity to take part in this effort which required a complete tum around in how the organization approached its mission. I will detail areas of responsibility given to me, and my contributions to the ongoing effort to become the first National Guard agency to acquire certification.

Master of Science / Investigations of fluvial and estuarine sediments have indicated stormwater is an important source of heavy metals to Port Jackson estuary and high concentrations of these sedimentary contaminants are a threat to the healthy functioning of the estuarine ecosystem. Stormwater remediation devices have been installed in stormwater channels entering the estuary, however these devices are mainly for removing gross pollutants and are ineffective in removing heavy metals from stormwater. A thorough characterisation of heavy metal inputs and behaviour has been undertaken by sampling, analysing and modelling heavy metals in stormwater entering Port Jackson estuary to provide a rigorous data base for future remediation efforts. A conceptual model of transport and fate of heavy metals in stormwater entering Port Jackson estuary has also been developed to identify heavy metals, subcatchments and flow regimes requiring remediation, and to assist in designing remediation devices for optimum removal of heavy metals from stormwater. Modelling of stormwater using the Model for Urban Stormwater Improvement Conceptualisation (MUSIC) indicated that the average annual discharge of stormwater from the Port Jackson catchment was 215,307 ML. Average annual loadings of arsenic, cadmium, chromium, copper, nickel, lead and zinc in stormwater discharging to Port Jackson estuary were 0.8, 0.5, 1.7, 3.2, 1.1, 3.6 and 17.7 tonnes per year, although comparison to other studies in the catchment suggests these values may be underestimations of actual loadings by 1.3 to 10 times. The proportion of heavy metals discharged under low-flow conditions (<5mm of rainfall in 24 hours), medium-flow conditions (between 5 and 50mm in 24 hours), and high-flow conditions (>50 mm of rainfall in 24 hours) was 6.5%, 62.5% and 31%, respectively. The conceptual model indicates stormwater loadings of copper, lead and zinc pose a risk to the health of riverine and estuarine ecosystems in the catchment and these metals should be targeted for remediation. Stormwater channels which should be prioritised for remediation include the channels entering southern embayments west of Darling Harbour; Duck, Parramatta and Lane Cove Rivers; and the channels and rivers entering Neutral, Long and Sugarloaf Bays. Stormwater loadings of lead are predominantly associated with suspended particulates, whereas loadings of copper and zinc are equally partitioned between dissolved and particulate phases. Stormwater remediation strategies should target both dissolved and particulate phases to ensure effective removal of copper, lead and zinc. Research suggests heavy metals in stormwater discharged to the estuary under high-flow conditions are rapidly exported seaward and bypass the estuary. Preliminary research also suggests that under medium-flow conditions, particulate heavy metals bypass the embayments of Port Jackson and are deposited in the main channel. Once deposited in the main channel, particulate heavy metals are likely to be remobilised and removed from the estuary through multiple phases of resuspension. Although further research is required in this area, this preliminary research suggests remediation should target low-flow conditions. The findings of the current research could be used to identify appropriate remediation strategies for dissolved and particulate phase heavy metals in stormwater discharging to Port Jackson estuary. However, in designing stormwater remediation devices, consideration should also be given to the range of contaminants that may be present in stormwater entering Port Jackson estuary (including suspended solids, nutrients, pesticides and organics).

Jackson County, Oregon is noted for the production of high quality pears. It is the fourth leading pear producing county in the United States and is the number one producer of winter pears. This thesis analyzes in detail the many aspects of the pear industry in the county. Climate, soils, topography, and progressive growers have been the main localizing factors. The study revealed that 200 growers produce the average annual total of three million boxes of pears on 9940 acres of bearing orchards. The pears are prepared for market in 12 packing houses and two canneries. The industry has a direct impact on the county of $15,000,000. The problems confronting the industry are caused by physical and biological factors. Spring frosts and hail damage are problems imposed by the climate. Pear Blight, Pear Decline, and Pear Scab are the main diseases. Insect pests such as the Pear Psylla and the Codling Moth must also be combatted. Urban encroachment has not yet been a serious problem in the county. The future for the industry appears to be stable, with little change in acreage. The fruit gift box industry will become of increasing importance, thus creating further emphasis on producing winter pears. / Graduation date: 1963
