Modis Snow-Cover Products, Dorothy K. Hall, George A. Riggs, Vincent V. Salomonson, Nicolo E. Digirolamo, Klaus J. Bayr

United States National Aeronautics and Space Administration: Publications

On December 18, 1999, the Terra satellite was launched with a complement of five instruments including the Moderate Resolution Imaging Spectroradiometer (MODIS). Many geophysical products are derived from MODIS data including global snow-cover products. MODIS snow and ice products have been available through the National Snow and Ice Data Center (NSIDC) Distributed Active Archive Center (DAAC) since September 13, 2000. MODIS snow-cover products represent potential improvement to or enhancement of the currently available operational products mainly because the MODIS products are global and 500-m resolution, and have the capability to separate most snow and clouds. The MODIS snow-mapping algorithms are …

United States National Aeronautics and Space Administration: Publications

With the launch of NASA’s Terra satellite and the MODerate Resolution Imaging Spectroradiometer (MODIS), operational Bidirectional Reflectance Distribution Function (BRDF) and albedo products are now being made available to the scientific community. The MODIS BRDF/Albedo algorithm makes use of a semiempirical kernel-driven bidirectional reflectance model and multidate, multispectral data to provide global 1-km gridded and tiled products of the land surface every 16 days. These products include directional hemispherical albedo (black-sky albedo), bihemispherical albedo (white-sky albedo), Nadir BRDF-Adjusted surface Reflectances (NBAR), model parameters describing the BRDF, and extensive quality assurance information. The algorithm has been consistently producing albedo and NBAR …

Wetland Replacement Practices And Procedures For Indiana Highway Projects, James E. Alleman, Steve M. Graves

JTRP Technical Reports

It is estimated that Indiana has already lost more than 80% of its original, native wetlands, and concerns have been expressed that some fraction, and perhaps even a sizable fraction, of these losses can be historically linked to highway construction associated with INDOT-related activities. These wetlands are important for several reasons, in that they help keep ground water and surface water clean, serve as reservoirs for floodwaters, help recharge groundwater, provide habitats for many species of animals, and serve as recreational areas. This underlying concern behind this accusation, therefore, is that the construction of state and federal roads historically carried …

Redefining American Democracy: Do Alternative Voting Systems Capture The True Meaning Of "Representation"?, James Thomas Tucker

Michigan Journal of Race and Law

This Article explores whether alternative voting systems are compatible with the meaning of representation in the United States. Part II begins by examining the role of geographical representation and the effect it has on the ability of individuals and groups of voters to give or withhold their consent. Part III follows this inquiry by assessing the relationship between representatives and constituents under majoritarian and proportional systems to determine the consequences of moving away from geographical representation towards models designed to enhance opportunities for all voters to choose winning candidates. A description of what a "majority" is and when and how …

The Place Of Dietary Practices In The Lives Of Older Women, Lisa Marie Curch

University of Kentucky Doctoral Dissertations

Studies have supported the benefits of positive dietary behaviors in preventing or reducing morbidity and extending longevity, as well as the psychosocial function of dietary practices for quality of life. Research is needed though on the dietary behaviors of elders in general and older women in particular, for whom gender affects lifelong dietary patterns. Health behavior theory has typically focused on psychological factors, to the neglect of sociocultural processes. This investigation utilized a life course perspective, enhanced by social interactionist elements, to address aspects of development and change in behavior neglected by health behavior theories, such as temporal dimensions and …

End The Moratorium: The Timor Gap Treaty As A Model For The Complete Resolution Of The Western Gap In The Gulf Of Mexico, John Holmes

Vanderbilt Journal of Transnational Law

The United States and Mexico recently entered into a treaty to delimit the continental shelf in the Gulf of Mexico, allowing both countries access to explore and exploit valuable natural resources in the Western Gulf. Included in the treaty is a ten-year moratorium on oil production within a buffer zone that encompasses transboundary reserves.

This Note explores the issues surrounding the buffer zone and suggests a model to resolve the dispute over access to transboundary reserves that will benefit both the United States and Mexico. Part 11 describes the relevant international law governing the Gulf of Mexico. Part III outlines …

Colombian Army Adaptation To Farc Insurgency, Thomas A. Marks Dr.

Books, Monographs & Collaborative Studies

The author points out that Revolutionary Armed Forces of Colombia (FARC) insurgents actively are pursuing a strategy to mobilize the disaffected and disposed people of Colombia, and to control the entire national territory. At the same time, he argues that no one in the national political establishment has taken the initiative to conduct an appropriate effort to deny FARC its objective. As a result, the Colombian Army has been left alone to direct the fight, without a coordinated and integrated national campaign plan or other resources that would allow for success. The author concludes that the Army has bought time, …

Development Of The Muskox Lungworm, Umingmakstrongylus Pallikuukensis (Protostrongylidae), In Gastropods In The Arctic, Susan J. Kutz, Eric P. Hoberg, John Nishi, Lydden Polley

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Development of the muskox protostrongylid lungworm, Umingmakstrongylus pallikuukensis, in its slug intermediate host, Deroceras laeve, was investigated under field conditions in the Arctic. Every two weeks, from 19 June to 28 August 1997, groups of ten experimentally infected slugs were placed in tundra enclosures in a mesic sedge meadow near Kugluktuk, Nunavut, Canada. First-stage larvae (L1) infecting slugs on or before 17 July developed to third-stage larvae (L3) in 4–6 weeks. Intensity of L3 in slugs peaked at 6–8 weeks post infection (PI) and then progressively declined by 10, 12, and 48–50 weeks PI. Abundance of L3 in …

Species Richness, Latitude, And Scale-Sensitivity, S. Kathleen Lyons, Michael R. Willig

School of Biological Sciences: Faculty Publications

The latitudinal gradient of species richness is well documented for a variety of taxa in both terrestrial and aquatic environs. Moreover, a number of recent attempts to assess the effects of scale on the relationship have concluded that the latitudinal pattern is scale-invariant. Nonetheless, the power of those approaches is predicated on precise knowledge of the forms of the latitudinal gradient, the area relationship, and their interaction. We used a model developed by J. Pastor, A. Downing, and H. E. Erickson for assessing the effects of scale on the productivity–diversity gradient to avoid such complications. More specifically, for 253 sets …

Foundations For An Integrative Parasitology: Collections, Archives, And Biodiversity Informatics, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Burgeoning awareness about biodiversity emphasizes the fundamental importance of museum collections and the contributions of systematists and taxonomists in documenting the structure and history of the biosphere. An essential role is served by this infrastructure in collecting, preparing, analyzing, and disseminating information about the specimens that represent species, document a range of complex biological associations from symbioses to parasitism, and form the tapestry and the myriad facets of biodiversity (e.g., Wilson, 2000). As parasitologists we can examine how we may contribute to this broader documentation and understanding of global biodiversity, and we can articulate and communicate our role as vital …

Protostrongylus Stilesi (Nematoda: Protostrongylidae): Ecological Isolation And Putative Host-Switching Between Dall’S Sheep And Muskoxen In A Contact Zone, Eric P. Hoberg, Susan J. Kutz, John Nagy, Emily Jenkins, Brett Elkin, Marsha Branigan, Dorothy Cooley

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The occurrence of Protostrongylus stilesi in a population of introduced muskoxen, Ovibos moschatus wardi, on the Arctic Coastal Plain, Yukon Territory (YT) and Northwest Territories (NT), Canada, is consistent with a contemporary colonization event from Dall’s sheep, Ovis dalli dalli, which indicates that host specificity may be ecologically based and contextual for this parasite. Colonization of muskoxen by P. stilesi may be a predictable event in zones of sympatry with Dall’s sheep; exposure to infection may coincide with occupation of winter ranges of Dall’s sheep by muskoxen during the summer season. Disruption of contemporary ecological isolating barriers can …

Early Holocene Change In Atmospheric Circulation In The Northern Great Plains: An Upstreamview Of The 8.2 Ka Cold Event, Walter E. Dean, Richard M. Forester, J. Platt Bradbury

United States Geological Survey: Staff Publications

Elk Lake, in northwestern Minnesota, contains numerous proxy records of climatic and environmental change contained in varved sediments with annual resolution for the last 10,000 years. These proxies show that about 8200 calendar years ago (8.2 cal. ka; 7300 radiocarbon years) Elk Lake went froma well-stratified lake that was wind-protected in a boreal forest to a well-mixed lake in open prairie savanna receiving northwesterly wind-blown dust, probably from the dry floor of Lake Agassiz. This change in climate marks the initiation of the widely recognized mid-Holocene “altithermal” in central North America. The coincidence of this change with the so-called 8.2 …

Implications Of Water Supply For Indigenous Americans During Holocene Aridity Phases On The Southern High Plains, Usa, Warren W. Wood, Stephen Stokes, Julie Rich

United States Geological Survey: Staff Publications

Springs in the 40 to 50 large lake basins (>15 km²) on the southern portion of the Southern High Plains (SHP) were active during periods of aridity in the Holocene when there may have been human habitation of the area. Eolian erosion of the lake floors and lunette accretion occurred as groundwater levels declined in response to decreased groundwater recharge. The declining lake floor associated with eolian erosion allowed groundwater evaporative discharge to continue, thus maintaining a groundwater gradient toward the lake. This hydrologic condition was favorable for a relatively continuous spring discharge to the lake, independent …

During the student teaching semester; they implemented the ideas and activities that they had created during the course. The paper presents the course syllabus; which offers a background on Hispanics and five sessions that emphasize how to reach Hispanic students; Mexican and Mexican American culture (holidays; food; art; and music); literature …

Band Selection And Algorithm Development For Remote Sensing Of Wildfires, Andrew Fordham

Theses

The environmental damage and global change caused by wildfires are fast becoming issues of local, regional and global concern. Remote sensing techniques are an ideal tool to use for monitoring these threats. Unfortunately, most existing satellites were built for other purposes and are less than ideal for the problems associated with detecting, assessing and monitoring fires. This thesis examines the phenomenology of fires and rank orders several non-traditional detection strategies that have the promise of being more cost effective and less susceptible to false alarms than existing satellite systems and algorithms. The possibility of detecting fires with multi-band "color" measurements …

Structural And Sedimentary Characteristics Of The Tsergo Ri Rockslide Breccia, Langtang, Nepal, Himalaya, Mark B. Carpenter

Theses and Dissertations (Comprehensive)

The high magnitude Tsergo Ri landslide (c. 100ka), Langtang Himal, with a volume in excess of 15km^3 and a vertical displacement of more than 1500m remains the largest crystalline rockslide in Nepal Himalaya. The Quaternary landslide affected rocks in gneissic fancies of the High Himalayan Crystalline Sequence adjacent to the Tibetan Sedimentary Series. Depositional characteristics from exhumed transport slope sites were analysed at both the macroscopic and the microscopic scale to investigate (i) localised fracture in terms of orientation and density, and (ii) petrography of slide induced host rock deformation. Fracture orientation analysis indicate the spatial orientation of preexisting discontinuities …

From Bricks And Mortar To Bricks And Clicks: The Transformation Of A Bank Branch Network Within The Greater Toronto Area (Ontario), Michelle Anne Mok

Theses and Dissertations (Comprehensive)

Over the last 20 years, Canadian retail financial services have undergone a dramatic transformation due to a number of driving forces: technology, globalization, changing lifestyles and demographics, competition, and deregulation. Because retail financial services have been impacted, the way Canadians perform banking transactions has also been impacted, resulting in a shift from a spatially-oriented banking approach to a non-spatial approach. Transactions are being performed using alternative delivery channels including the automated banking machine, telephone banking, internet banking, point of sale purchasing, and new format branches, rather than in the traditional branch network. This research examines changes in the branch network …

Institutional processes, social and economic trends play a role in defining the outcomes of people’s interaction with and use of their ecosystems. The resource use decisions of households influence the livelihood and health dimensions of ecological change. This thesis identifies community assets and activities, and examines how they both affect human and ecological health, productivity and community sustainability. It studies the relationship between changing biophysical conditions and community well-being in terms of health and livelihood by examining how agro-ecosystem based resource use systems influence community environmental change and vulnerability to health and livelihood problems inherent in their ecosystem. Three communities …

Seiche Events At The Slave River Delta And Great Slave Lake, Northwest Territories: An Assessment Of Process And Impact, James Tobias Gardner

Theses and Dissertations (Comprehensive)

Seiche events are important hydrodynamic processes that impact the Slave River Delta, during the late summer and autumn. Given the scarcity of previous research on seiche events at river deltas and the physical dimensions and orientation of the Slave River Delta, this location at the southern shore of Great Slave Lake is ideal to study the occurrence and impacts of seiche events at a river delta. Seasonal changes to long-term water level trends and water level variability on Great Slave Lake, correspond to changes to the Slave River flow potentially associated with the impacts of regulation of the Peace River. …
