Perceptions Of Businesses On Environmental Regulatory Information, Kimberly K. Gunderson
Perceptions Of Businesses On Environmental Regulatory Information, Kimberly K. Gunderson
Dissertations and Theses @ UNI
The purpose of this study was to determine the source and amount of information that a sample of businesses receive on environmental regulatory topics and from what sources they would prefer to receive this information. More specifically, the study demonstrated the discrepancy between the sources from which businesses currently receive their information and the sources from which they would prefer to receive it. The study also addressed how relevant this information was to the businesses and with which regulations the businesses were the most and least knowledgeable. The study was done by conducting a mail-back survey of 500 Iowa small …

An Assessment Of Hydrological Process And Landform Change: Slave River Delta, Northwest Territories, Ronald Brad Hill
An Assessment Of Hydrological Process And Landform Change: Slave River Delta, Northwest Territories, Ronald Brad Hill
Theses and Dissertations (Comprehensive)
The Slave River Delta, 61˚15'N, 113˚30'W, is located at the mouth of the Slave River in the southeast arm of Canada's Great Slave Lake. Although the delta itself lies some 1600 km downstream from the W.A.C. Bennett Dam at Hudson's Hope, British Columbia, the mean annual discharge and sediment load of the Slave River have decreased by 16% and 33% respectively since regulation. Such alterations in the Slave River flow regime have significant implications for the growth of the River Delta since the transfer of sediment to the delta front is one of the most important factors in the landform’s …
Teaching Secondary School Geography With The Use Of A Geographical Information System (Gis), Angela Louise Crechiolo
Teaching Secondary School Geography With The Use Of A Geographical Information System (Gis), Angela Louise Crechiolo
Theses and Dissertations (Comprehensive)
Until quite recently, geographical information systems have been limited to the resources and students of post-secondary institutions. This situation is now changing in Ontario. In the early 1990's the Ministry of Education adopted mandates to develop curriculum guidelines for the integration of computers into all areas of the curriculum. Although the process is well underway in Ontario, limited access to hardware and software, insufficient pre-service and in-service training, and a paucity of teaching resources has lead to mounting teacher frustration. Although the literature base on teaching GIS at the pre-collegiate level is increasing, it lacks clearly defined examples of how …
Industrial Trade Shows: Their Role And Spatial Dimension In Industrial Restructuring, Andras Gosztonyi
Industrial Trade Shows: Their Role And Spatial Dimension In Industrial Restructuring, Andras Gosztonyi
Theses and Dissertations (Comprehensive)
The fundamental changes in the economic environment since the 1970s put firms under immense pressure to adjust their strategies to the increasingly dynamic and flexible global economy. The simultaneous upsurge in industrial trade show activity suggests that these events hold a central position in the process of restructuring. Therefore this study aims at theoretically examining the economic functions of trade shows and thus their role in economic restructuring. Yet, if trade shows are significant in industrial restructuring, it is important to learn about their spatial structure and thus their accessibility to firms in different countries and regions. This is carried …
The Impact Of Glacier Recession Upon The Discharge Of The Bow River Above Banff, Alberta, 1951-1993, Christopher Dennis Hopkinson
The Impact Of Glacier Recession Upon The Discharge Of The Bow River Above Banff, Alberta, 1951-1993, Christopher Dennis Hopkinson
Theses and Dissertations (Comprehensive)
Three methods have been used to explore the volumetric change of glaciers in the Bow Basin above Banff for the years 1951 to 1993. Using aerial photography, the extent of glacier covers for the two years were mapped at a scale of 1:50,000. The first volumetric calculation of glacier loss was based on inventory criteria; the second a hyposgraphic curve method based on Young’s investigations in Mistaya Basin (1991) and the third stereo air photogrammetry and DEM comparisons using computer software. These methods were applied to the highly glacierized Hector Lake catchment within the Bow Valley and then extrapolated up …
Small Mammals Of Point Pelee National Park: Protecting Biodiversity In Small Reserves (Ontario), Julie Ann Spicer
Small Mammals Of Point Pelee National Park: Protecting Biodiversity In Small Reserves (Ontario), Julie Ann Spicer
Theses and Dissertations (Comprehensive)
Habitat destruction, fragmentation and degradation have been widespread throughout southern Ontario with devastating effects on wetlands. Small reserves are all that in this highly agricultural/urban landscape to protect the biodiversity of Great Lakes Marsh and Carolinian Forest ecosystems. Small reserves are vulnerable to species loss through a host of problems related to size and as a result, the value of small reserves to conservation strategies has often been questioned. Indicator species can be used as a means of studying the conditions of complex ecosystems. In this research, small mammals were sampled in the wetlands of Point Pelee National Park as …
Spatial Distribution Of Lead In Soil And Sediment In Iqaluit, Northwest Territories And Links With Human Health, Liisa Ann Peramaki
Spatial Distribution Of Lead In Soil And Sediment In Iqaluit, Northwest Territories And Links With Human Health, Liisa Ann Peramaki
Theses and Dissertations (Comprehensive)
The Baffin Regional Health Board has recently expressed concern over lead poisoning in Iqaluit, NWT, manifested by low haemoglobin levels in children. Several studies in temperate regions have demonstrated links between environmental lead and human health. However, little is known about these links in a permafrost environment. While humans are exposed to lead via a number of different pathways, soils and sediments are two major pathways. The purpose of this study is to determine the spatial distribution of soil and sediment-associated lead in Iqaluit and to assess probable pathways between high lead levels and children. The research hypothesis is that …
Reexamination Of Scarp Development Along The Niagara Escarpment, Ontario, Canada, David Walter Hintz
Reexamination Of Scarp Development Along The Niagara Escarpment, Ontario, Canada, David Walter Hintz
Theses and Dissertations (Comprehensive)
The Niagara Escarpment is generally viewed as a relict landform which shows ancient structural features and the effects of glaciation. Since it was realized that the Escarpment was not a fault, but instead a feature of erosional origin, little interest has been paid to development of the steep cliffed section of the Niagara Escarpment. This research project has several objectives. The first is an examination of the relationship between the morphology of the Escarpment and its geological units. This will include analysis of the structure and lithology of each and the geochemistry, especially, of the Queeston Formation. Associated with the …
A Sensitivity Analysis Of The Hydrology Of The Bow Valley Above Banff, Alberta Using The Ubc Watershed Model, Alexi Zawadzki
A Sensitivity Analysis Of The Hydrology Of The Bow Valley Above Banff, Alberta Using The Ubc Watershed Model, Alexi Zawadzki
Theses and Dissertations (Comprehensive)
Snow and ice meltwater constitutes a significant portion of westem Canada's water resources for residential, industrial and agricultural uses. As a consequence, temporal variations in climate will have a marked effect on the local hydrology of the Canadian Rocky Mountains, especially as glaciers, glacierettes and snow packs decrease in size or melt out. It is therefore very important for hydrologists to accurately understand the climatic sensitivity of glacierized watersheds in order to predict and prepare for potentially dramatic variations in the future water budget. This thesis proposes a methodology for the estimation of the hydrological response of a large, temperate, …
Fluid Patterns, Sediment Pathways And Woody Obstructions In The Pine River, Angus, Ontario, John T. Beebe
Fluid Patterns, Sediment Pathways And Woody Obstructions In The Pine River, Angus, Ontario, John T. Beebe
Theses and Dissertations (Comprehensive)
The objective of this research was to determine the effects that woody obstructions have on flow patterns and sediment pathways in a sand-bed river in Central Ontario. The Pine River near Angus, a tributary of the Nottawasaga River, was chosen because it contained a number of woody obstructions to flow from which to choose study sites. Two reaches, one containing a trunk oriented in the direction of flow, were chosen as the study reaches. Sampling of fluid speeds through the study reaches showed that the cross-stream obstruction acted to slow fluid as it approached and exited the obstruction zone, while …
Analysis Of The Utility Of A Normalized Difference Vegetation Index For Inventorying Urban Greenspace, Thomas J. Dobbs
Analysis Of The Utility Of A Normalized Difference Vegetation Index For Inventorying Urban Greenspace, Thomas J. Dobbs
Electronic Theses and Dissertations 1990 - 1999
Satellite derived vegetative data of urban areas is normally classified into several classes of trees, fields, grass and bare soil using unsupervised and supervised classification methods. Normalized Difference Vegetation Indexes (NDVI) have traditionally been applied to agricultural satellite images to assess the health and maturity of commercial crops. When a NDVI is used to examine urban vegetation, many discrete data values are generated which can be differentiated into meaningful vegetation classes.
Behavior Of Eccentrically Loaded Slender Concrete Columns Reinforced With Cfrp Bars, Wei. Xia
Behavior Of Eccentrically Loaded Slender Concrete Columns Reinforced With Cfrp Bars, Wei. Xia
Electronic Theses and Dissertations 1990 - 1999
In a highly corrosive environment, corrosion is the main factor leading to deterioration and eventual failure of conventional reinforced or prestressed concrete structures. Carbon Fiber Reinforced Plastics (CFRP) are considered as an alternative to steel reinforcement due to its excellent corrosion resistance. This investigation was conducted to establish the feasibility of using CFRP cables as reinforcing elements in reinforced concrete columns. Besides investigating durability of CFRP cables in adverse environments (alkali and sea water) experimental and theoretical studies were carried out to study the behavior of CFRP reinforced concrete slender columns under combined axial load and bending moment. Exposure to …
