In this paper, we discuss gigabit network applications enabled by "Mission to Planet Earth," an international effort to monitor the Earth as a system. We describe the design of a network architecture to support applications developed as part of this program; introduce a new component, public access resource centers (PARC9s); and discuss how PARC's would facilitate access by users outside the traditional research community. We also describe how a particular class of users, agriculture users, might to Planet Earth program and delivered in a value-added form to them by a so-called AgPARC. The suggested architecture requires the deployment of high-bandwidth …

From Marx To Markets: Reform Of The University Economics Curriculum In Russia, Stanley L. Brue, Craig Macphee May 1995

From Marx To Markets: Reform Of The University Economics Curriculum In Russia, Stanley L. Brue, Craig Macphee

Department of Economics: Faculty Publications

In June 1992, we taught a three-week seminar at Moscow State University that coincided with the beginning of a historic curriculum reform in Russia. The reform had two parts: (I) the replacement of the Marxist-Leninist three-year sequence of courses in political economy with a sequence on market economics and (2) substantial revision of other course requirements for the economics degree. br>
The occasion of our Russian visit was an invitation from Moscow State University to present a seminar on the principles of market economics. The seminar demonstrated the typical content and teaching techniques used in the American micro-macro principles course. …

Private Beaver Management In Oklahoma, Julianne Whitaker Apr 1995

Private Beaver Management In Oklahoma, Julianne Whitaker

Great Plains Wildlife Damage Control Workshop Proceedings

The Oklahoma Department of Wildlife Conservation (ODWC) estimated the state's beaver (Castor canadensis) population at 1,245 animals in 1951-52. That same year, ODWC relocated 29 beaver from 5 western counties to Department lands in 4 eastern counties. Beaver populations in Oklahoma have since grown as a result of changes in available habitat. In response to the growing number of beavers, ODWC opened an annual beaver season from 1 December to 31 January, in 1960-1961. The season was opened year-round in 1983. Although beaver activities benefit many wildlife species, their activities have had a negative economic impact on the …

United States V. Steinmetz: The Legal Legacy Of The Civil War, Revisited, Susan Poser, Elizabeth R. Varon Apr 1995

United States V. Steinmetz: The Legal Legacy Of The Civil War, Revisited, Susan Poser, Elizabeth R. Varon

Nebraska College of Law: Faculty Publications

One of the enduring and yet unresolved issues concerning the Civil War is its legal nature: Was it an insurrection or an international war? During the war and since, the United States courts have repeatedly been called upon to determine the status of property which was under the control of the Confederacy and its agents during the Civil War. In the process of making such determinations, the courts have reopened questions about the war's legal status. United States v. Steinmetz is such a case.

Satellite-Based Herbaceous Biomass Estimates In The Pastoral Zone Of Niger, Bruce K. Wylie, Issa Denda, Rex D. Pieper, John A. Harrington Jr., Bradley C. Reed, G. Morris Southward Mar 1995

Satellite-Based Herbaceous Biomass Estimates In The Pastoral Zone Of Niger, Bruce K. Wylie, Issa Denda, Rex D. Pieper, John A. Harrington Jr., Bradley C. Reed, G. Morris Southward

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Pastoralists in the Sahel of northern Africa are entirely dependent on their livestock, which graze on the annual vegetation produced during a relatively short summer rainfall season. The satellite-based normalized difference vegetation index, calibrated with ground-truth sampling of herbaceous biomass throughout the pastoral zone of Niger, was used to estimate standing biomass for the entire Nigerien pastoral zone. Data were obtained and analyzed during a 5-year period from 1986 through 1990. Techniques developed allow officials with the Government of Niger to estimate herbage available to support animal populations throughout the pastoral zone at the end of the growing season and …

Book Review: Quaternary Geology And Geomorphology Of South America By C. Clapperton, William J. Wayne Mar 1995

Book Review: Quaternary Geology And Geomorphology Of South America By C. Clapperton, William J. Wayne

Department of Earth and Atmospheric Sciences: Faculty Publications

Dr. Clapperton is to be commended for having taken on the monumental task of a review of the present state of knowledge of the Quaternary of the entire continent of South America. Quaternary Geology and Geomorphology of South America is a massive, interestingly written, but expensive volume that covers exactly what its title suggests. In spite of the paucity of information on many aspects of the Quaternary geology of this continent, which extends from north of the equator nearly to the Antarctic, the author has succeeded in reviewing and synthesizing most of the material that does exist. To do so …

Water Regulation Decisions In Central Kansas Affecting Cheyenne Bottoms Wetland And Neighboring Farmers, Leslie Aileen Duram Feb 1995

Water Regulation Decisions In Central Kansas Affecting Cheyenne Bottoms Wetland And Neighboring Farmers, Leslie Aileen Duram

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

A water use regulation order by the Chief Engineer of the Division of Water Resources of the Kansas State Board of Agriculture addressed a controversial issue: water allocation for agricultural, wetland, and urban users in Central Kansas. The specific study area includes Cheyenne Bottoms Wetland, a preserve with important habitat conditions for many migratory bird species. This region is economically dependent on irrigated agriculture. Groundwater withdrawal for irrigation had caused the water table to decline and left the wetland with no consistent water source. The Chief Engineer required many farmers to reduce their irrigation water use. An evaluation of this …

Hydroclimatic Perspectives On Waterfowl Production In The North Dakota Prairie Pothole Region, Paul Todhunter Feb 1995

Hydroclimatic Perspectives On Waterfowl Production In The North Dakota Prairie Pothole Region, Paul Todhunter

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

The North Dakota Prairie Pothole Region is one of the most unique and important wetland environments for waterfowl in North America. A water balance climatology is developed for this region for the period 1895-1990. A monthly water balance time series for the 96-year period was computed utilizing the Thornthwaite water balance methodology and a regional time series developed from area-weighted National Climate Data Center divisional data. Results illustrate the unique seasonal dynamics of the mean soil moisture regime, the frequency distribution of selected water balance variables over the period of record, and the large intra-annual and interannual variability which characterizes …

Review Of Forgotten Places: Uneven Development In Rural America Edited By Thomas A. Lyson And William W. Falk, Karen Morin Feb 1995

Review Of Forgotten Places: Uneven Development In Rural America Edited By Thomas A. Lyson And William W. Falk, Karen Morin

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

The editors and authors of this fine collection of articles, though mostly sociologists, demonstrate how geography is in a sense destiny to the rural poor. By focusing on nine regions spanning the country from New England to the Rio Grande Valley to the Pacific Northwest, they show how social as well as spatial isolation has created common problems among a rural underclass that is "forgotten" by mainstream America.

Socio-spatial isolation may take many forms, but the outcome for all the places studied is the same: lack of full participation in American economic life. Educational isolation in the Black Belt of …

Changing Employment Patterns On The Northern And Central Great Plains, Richard E. Lonsdale, J. Clark Archer Feb 1995

Changing Employment Patterns On The Northern And Central Great Plains, Richard E. Lonsdale, J. Clark Archer

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

The Great Plains are sometimes characterized as an economically lagging region. To shed some light on the region’s prospects, the locational and structural changes in employment patterns in the northern and central Great Plains were examined for the 1980 to 1990 period. County-level data were drawn from CD-ROM census publications and matched with locational references using Atlas *GIS . Shift-share computations were undertaken for the region as a whole and for metropolitan and nonmetropolitan counties. Employment declined sharply in agriculture and construction, but increased in the service sectors. Compared with the nation as a whole, the region competed poorly in …

Review Of Colorado: The Place Of Nature, The Nature Of Place By Thomas P. Huber, A. David Hill Feb 1995

Review Of Colorado: The Place Of Nature, The Nature Of Place By Thomas P. Huber, A. David Hill

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Colorado contains profiles of twelve distinctive places, which like the pieces of a jig-saw puzzle, fit together to form a mosaic that helps describe and explain the state's natural and, to a lesser extent, human history. The opening chapter introduces the lay reader to the broad themes of the state's physical geography-geology, landforms, climate, and vegetation. These topics are then typically covered with specific reference to each of the place profiles that constitute the remaining twelve chapters.

The most intriguing aspect of the book is the selection of the twelve places. Huber said he chose them "to inform, tantalize, and …

Drought Evolution Patterns In The U.S.A. During Great Plains-Centered Droughts, Peter T. Soule Feb 1995

Drought Evolution Patterns In The U.S.A. During Great Plains-Centered Droughts, Peter T. Soule

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

This study examines the spatial evolution of drought severity within the contiguous United States during the first six months of average Great Plains-centered drought events. It identifies Great Plains-centered drought events from 1895-1989 based on the drought history of the North Central, South Dakota and Low Rolling Plains, Texas climatic divisions. Time series of warm- and cold-season average drought severity based on Great Plains drought for all United States' climatic divisions are calculated and spatially analyzed.

Mapped patterns show spatial teleconnections in drought development. Cold-season drought patterns based on the North Central, South Dakota climatic division are clearly in-phase with …

Seasonal Land-Cover Regions Of The United States, Thomas R. Loveland, James W. Merchant, Jesslyn F. Brown, Donald O. Ohlen, Bradley C. Reed, Paul Olson, John Hutchinson Jan 1995

Seasonal Land-Cover Regions Of The United States, Thomas R. Loveland, James W. Merchant, Jesslyn F. Brown, Donald O. Ohlen, Bradley C. Reed, Paul Olson, John Hutchinson

School of Natural Resources: Faculty Publications

Research on global change has been hindered by deficiencies in the availability Wand quality of land-cover data (Mather and Sdasyuk 1991; Townshend 1992). To address this deficiency, the U.S. Geological Survey (USGS) and the University of Nebraska- Lincoln have collaborated in developing a method of land-cover characterization that is suitable for research on global change and on regional patterns of land cover (Loveland et al. 1991; Brown et al. 1993). This methodology is based upon statistical analysis of multidate, meteorological satellite imagery acquired by the National Oceanic and Atmospheric Administration's (NOAA) Advanced Very High Reso- lution Radiometer (AVHRR) sensor complemented …

Bermuda Solution Pipe Soils: A Geochemical Evaluation Of Eolian Parent Materials, Stanley R. Herwitz, Daniel R. Muhs Jan 1995

Bermuda Solution Pipe Soils: A Geochemical Evaluation Of Eolian Parent Materials, Stanley R. Herwitz, Daniel R. Muhs

United States Geological Survey: Staff Publications

Solution pipes found in the Quaternary eolian and marine carbonates of Bermuda are filled with reddish to reddish-brown soil material. The bulk of the soil is composed of clay and silt-sized quartz and aluminosilicate clay minerals. The carbonates are of high purity and, therefore, are not likely to have been the parent material. Previous workers have hypothesized that Saharan dust may have been the soil parent material. The fine-grained component of loess from the Mississippi River Valley of North America also could have contributed. Paleoclimate models indicate that both North Africa and North America could have been important source areas …

Review Of Soils In Archaeology: Landscape Evolution And Human Occupation Vance T. Holliday, William C. Johnson Jan 1995

Review Of Soils In Archaeology: Landscape Evolution And Human Occupation Vance T. Holliday, William C. Johnson

Great Plains Quarterly (through 2013)

Soils in Archaeology consists of papers representing the proceedings of the Fryxell Symposium held at the annual meetings of the Society for American Archaeology (SAA) in Phoenix during April 1988. This is a volume that deals with soil science applications to archaeology: the various papers discuss the application of soils science to reconstruction of past landscapes and their evolution, estimation of surface age and depositional episodes, and provide physical and chemical indications of human presence. The volume provides good examples of archaeological geology (geoarchaeology) as executed by four physical geographers, two geologists, an archaeologist and a soil scientist.

The 1992 Secession Movement In Southwest Kansas, Peter J. Mccormick Jan 1995

The 1992 Secession Movement In Southwest Kansas, Peter J. Mccormick

Great Plains Quarterly (through 2013)

In May of 1992 the Kansas state legislature approved and Governor Joan Finney signed into law a new school finance formula that adversely affected several southwest Kansas counties. The new bill provided for a blanket mill levy of 32 mills ($32 in taxes for every $1000 assessed valuation) to be spread across the state. It also restricted funding to a maximum of $3600 per student. The effects in the southwest were drastic. Many districts there, accustomed to setting their own tax rates and to retaining all monies collected, spent upward of $5000 per student on tax levies below 20 mills. …

The Front .. Gabled Log Cabin And The Role Of The Great Plains In The Formation Of The Mountain West's Built Landscape, Jon T. Kilpinen Jan 1995

The Front .. Gabled Log Cabin And The Role Of The Great Plains In The Formation Of The Mountain West's Built Landscape, Jon T. Kilpinen

Great Plains Quarterly (through 2013)

Students of American material culture have often viewed the arid, largely treeless Great Plains as an innovative source region of various aspects of western culture, especially those that gained expression on the landscape. While barbed wire and sod construction are two familiar examples, another exists in the front-gabled log dwelling, the dominant traditional building form of the Mountain and Inter-mountain Western frontier. Because the front-gabled log dwelling was indeed common on the Plains and reputedly absent in the forested, eastern United States, scholars have identified the Great Plains as the source region of this vernacular floorplan. Recent field and secondary …

Review Of North American Cattle-Ranching Frontiers: Origins, Diffusion, And Differentiation By Terry G. Jordan, Brad A. Bays Jan 1995

Review Of North American Cattle-Ranching Frontiers: Origins, Diffusion, And Differentiation By Terry G. Jordan, Brad A. Bays

Great Plains Quarterly (through 2013)

In this important companion to his earlier book, The American Backwoods Frontier, Terry Jordan has again taken the study of cultural diffusion into a new realm of inquiry and interpretation. Although mainly a synthesis of a vast and interdisciplinary literature, North American Cattle Ranching Frontiers offers a revisionist explanation of the origins, spread, and patterns of cattle ranching in most of North America, Mexico, and the Caribbean. This study will prove to be an even more innovative and controversial work than Backwoods, for the questions asked and the solutions provided are grand ones indeed. A cultural geographer, Jordan tailors …

Some Observations On The Labor Force Of The Canadian Ranching Frontier During Its Golden Age, 1882 .. 1901, Simon M. Evans

Great Plains Quarterly (through 2013)

It is more than a decade since scholars like L. G. Thomas and David H. Breen challenged the assumption that the Canadian ranching frontier was a straightforward case of technological and land-use diffusion from the United States. Breen argued that the Canadian government had played a significant role in bringing the range cattle industry into being within the North West Territories during the 1880s and went on to trace the manner in which the Department of the Interior overtly supported the ranchers for the next twenty years. Under this regulatory umbrella, upheld by the forceful presence of the North West …

Review Of An Unspeakable Sadness: The Dispossession Of The Nebraska Indians By David J. Wishart, Francis Paul Prucha Jan 1995

Review Of An Unspeakable Sadness: The Dispossession Of The Nebraska Indians By David J. Wishart, Francis Paul Prucha

Great Plains Quarterly (through 2013)

This is a well-written and authoritative book, but it is not a pleasant book to read, for it is a story of unremitting sadness. It traces the nineteenth-century history of four Indian tribes whose homelands in 1800 covered what is now the eastern two-thirds of the state of Nebraska-the Omahas and the Otoe-Missourias along the Missouri River, the Pone as north of the Niobrara River near its mouth, and the Pawnees (in four bands) in the central area of the state.

Sense Of Place In The Prairie Environment Settlement And Ecology In Rural Geary County, Kansas, Nina Veregge Jan 1995

Sense Of Place In The Prairie Environment Settlement And Ecology In Rural Geary County, Kansas, Nina Veregge

Great Plains Quarterly (through 2013)

Many people who drive across Kansas on the Interstate or on Route 50 see the state as a single, unchanging stretch of treeless plain. A more perceptive observer witnesses the gradual transition from the east to the west: from rolling hills and wooded vales to wide open grassland and sage plain; from corn to winter wheat; from farms to ranches and feedlots; from running streams to dry washes; from humidity on a summer day that is relieved only by constant wind to dry heat blown across grassland untempered by stream valley microclimates. It appears a seamless transition where distinctions are …

Bluestem And Tussock Fire And Pastoralism In The Flint Hills Of Kansas And The Tussock Grasslands Of New Zealand, James F. Hoy, Thomas D. Isern Jan 1995

Bluestem And Tussock Fire And Pastoralism In The Flint Hills Of Kansas And The Tussock Grasslands Of New Zealand, James F. Hoy, Thomas D. Isern

Great Plains Quarterly (through 2013)

The ghost of Lady Barker haunts public discourse on the question of burning tussock grassland in New Zealand. The image of this gentle English woman, author of the Canterbury classic Station Life in New Zealand, transformed into a pastoral pyromaniac professing "the exceeding joy of 'burning,'" is compelling. She contests with friends over who can set the most magnificent blaze, exults at solitary cabbage trees exploding into flame, and regrets that she was not there to see the first blaze rage across the plains. Of this ritual, she says, she and her friends "never were allowed to have half …

Placing The Places In Wordsworth's 1802 Sonnets, Stephen C. Behrendt Jan 1995

Placing The Places In Wordsworth's 1802 Sonnets, Stephen C. Behrendt

Department of English: Faculty Publications

Wordsworth's political sonnets of summer and fall 1802 recount the sights and sounds the poet encountered during the brief respite provided by the Peace of Amiens, which enabled him to return to France and to the woman and child who were the physical reminders of the time he had spent there ten years earlier in the spirited days following the French Revolution. Published together in 1807 in Poems, in Two Volumes, they juxtapose the dispirited and pathetic state of France in 1802 with the ebullience Wordsworth recalled from that earlier time. More important, the sequence documents his "return" to England, …

Evidence Of Active Dune Sand On The Great Plains In The 19th Century From Accounts Of Early Explorers, Daniel R. Muhs, Vance T. Holliday Jan 1995

Evidence Of Active Dune Sand On The Great Plains In The 19th Century From Accounts Of Early Explorers, Daniel R. Muhs, Vance T. Holliday

United States Geological Survey: Staff Publications

Eolian sand is extensive over the Great Plains of North America, but is at present mostly stabilized by vegetation. Accounts published by early explorers, however, indicate that at least parts of dune fields in Nebraska, Colorado, Kansas, New Mexico, and Texas were active in the 19th century. Based on an index of dune mobility and a regional tree-ring record, the probable causes for these periods of greater eolian activity are droughts, accompanied by higher temperatures, which greatly lowered the precipitationto- evapotranspiration ratio and diminished the cover of stabilizing vegetation. In addition, observations by several explorers, and previous historical studies, indicate …

Paleoecological Implications Of Plant/Animal Grazing Relations On The Mammoth Steppe Of Eastern Beringia, Andre Antinori Jan 1995

Paleoecological Implications Of Plant/Animal Grazing Relations On The Mammoth Steppe Of Eastern Beringia, Andre Antinori

Nebraska Anthropologist

This paper reassesses the areal extent of Mammoth Steppe in Eastern Beringia and discusses some of the ways in which grazing and topography entered into the maintenance of the Mammoth Steppe. Large, generalist grazing mammals, by their grazing style, helped maintain the Mammoth Steppe by removing old-growth and by stimulating grass plants to reproduce vegetatively. These grazers also promoted uniformity in growth-form and uniformity in plant biomass (phytomass) above and below the ground surface. During the late Pleistocene these large, generalist grazers were eliminated from interior Alaska by Paleolndian hunters and their predatory animal companions. The loss of these large, …

Geophagy: Adaptive Or Aberrant Behavior, David E. Engberg Jan 1995

Geophagy: Adaptive Or Aberrant Behavior, David E. Engberg

Nebraska Anthropologist

Geophagy, clay or dirt eating, is a worldwide phenomenon of long historical precedence. Historically perceived as an irrational behavior, today, growing evidence supports the contention that earth eating has adaptive value. Case studies from Africa and the United States illustrate the practice. A literature review shows that three primary explanations have been offered to account for the presence of geophagy in human populations. The first argues that geophagy has medicinal value as an anti-diarrheal and as a dietary supplement in vitamin and mineral poor environments. The Second contends that geophagy is a culturally transferred practice. The third states that earth …

The Identification Of Individuals With Disabilities In National Databases: Creating A Failure To Communicate, Kevin S. Mcgrew, Bob Algozzine, James E. Ysseldyke, Martha L. Thurlow, Amy N. Spiegel Jan 1995

The Identification Of Individuals With Disabilities In National Databases: Creating A Failure To Communicate, Kevin S. Mcgrew, Bob Algozzine, James E. Ysseldyke, Martha L. Thurlow, Amy N. Spiegel

Department of Educational Psychology: Faculty Publications

The purpose of this study was to analyze similarities and differences in how students with disabilities are identified in national databases. National data collection programs in the United States Departments of Education, Commerce, Labor, Justice, and Health and Human Services, as well as databases from the National Science Foundation, the American Council of Education, and the College Board, were examined. Nineteen national data collection programs were selected as being potentially useful in the extraction of policy-relevant information on the educational status and performance of students with disabilities. Among these 19 programs there was significant variability in the disability categories used. …
