Estimation In The Presence Of Measurement Error, Wayne A. Fuller Dec 1994

Estimation In The Presence Of Measurement Error, Wayne A. Fuller

CARD Staff Reports

The importance of measurement error for parameter estimation and for the design of statistical studies, particularly sample surveys, is examined. Beginning with a brief review of Hansen's contributions, the discussion concentrates on estimation problems in which measurement error leads to bias in the usual estimators. Estimation of distribution functions and regression equations are discussed, and the implications for the design of surveys are presented.

Nutrient Use Efficiency: An Ecological Approach, Cynthia A. Cambardella Dec 1994

Nutrient Use Efficiency: An Ecological Approach, Cynthia A. Cambardella

Proceedings of the Integrated Crop Management Conference

The practice of agriculture by humankind intentionally disturbs the nutrient and energy balance (especially Nand C) of natural ecological systems to produce the food, feed, and fiber needed to sustain human activities. These disturbed ecological systems are generally referred to as agroecosystems. A sustainable agroecosystem is one managed for the long-term profitable production of food, feed, or fiber while utilizing the full potential of biological, chemical and physical processes to conserve natural resources and minimize environmental damage (Elliott et al., 1993). Low nutrient-use efficiency is a major factor contributing to the non-sustainability of agroecosystems. To improve efficiency, a more complete ...


Grid Soil Sampling For Precision And Profit, N. C. Wollenhaupt, R. P. Wolkowski Dec 1994

Grid Soil Sampling For Precision And Profit, N. C. Wollenhaupt, R. P. Wolkowski

Proceedings of the Integrated Crop Management Conference

Site specific management of plant nutrients for crop production begins with an inventory of soil test levels in a field. Fertilizer recommendations are based on the expected response to addition of fertilizers as a function of soil test levels. Therefore, the accuracy of site specific fertilizer applications depends on how accurately the nutrient status of soils is mapped. Mapping accuracy usually increases as fields are divided and sampled as smaller areas.


Site Specific Management: The Pros, The Cons, And The Realities, F. J. Pierce, P. C. Robert, G. Mangold Dec 1994

Site Specific Management: The Pros, The Cons, And The Realities, F. J. Pierce, P. C. Robert, G. Mangold

Proceedings of the Integrated Crop Management Conference

Site specific management (SSM) for agriculture involves the variable management of soils and crops according to localized conditions within a field. Known by many other names, such as "Grid Farming", "Farming by Soils" or "Variable Rate Technology (VRT), SSM is a rapidly emerging set of technologies that allow farmers to manage their soils and crops on-the-go as equipment moves across a field. In essence, SSM is about doing the right thing, at the right time, in the right place, in the right way. Thus, SSM is intuitively appealing because it represents a means of improving the economic and environmental performance ...


A Survey Of Source And Finished Water Supplies For Giardia Cysts And Cryptosporidium Oocysts, Lisa Martin Sexton Dec 1994

A Survey Of Source And Finished Water Supplies For Giardia Cysts And Cryptosporidium Oocysts, Lisa Martin Sexton

KWRRI Research Reports

The occurrence of Giardia lamblia cysts and Cryptosporidium parvum oocysts was determined from source and treated drinking water supplies at selected water treatment facilities in Eastern Kentucky. Giardia and Cryptosporidium are two human protozoan parasites often found in water supplies due to fecal contamination. Characteristic cysts and oocysts were identified from large volume water samples, typically 100 gallons for raw samples and 1,000 gallons for finished water, using an indirect fluorescent antibody specific for Giardia and Cryptosporidium. Source water from four different water treatment facilities utilizing a reservoir, river, and two creeks were assayed. All sites exhibited Giardia lamblia ...

Using Biodiversity Data To Assess Species--Habitat Relationships In Glacier National Park, Montana, Diane M. Debinski, Peter F. Brussard Nov 1994

Using Biodiversity Data To Assess Species--Habitat Relationships In Glacier National Park, Montana, Diane M. Debinski, Peter F. Brussard

Diane M. Debinski

Biodiversity surveys are becoming increasingly popular. However, standard analysis techniques for these data have not yet been developed. This paper explores the use of multivariate ordination techniques for assessing species—habitat relationships using biodiversity data. The research was conducted in Glacier National Park, Montana, and birds and butterflies were chosen as the taxonomic groups of study. Biodiversity assessment sites were established throughout a range of habitats and monitored from 1987 through 1989. Presence/absence sampling over the total number of sampling sites was used to classify species commonness and rarity. Approximately 86% of the historically recorded butterflies and 70% of ...


Potato Cultivar Differences Associated With Mealiness, Diane R. Mccomber, Harry T. Horner, Mark A. Chamberlin, David F. Cox Nov 1994

Potato Cultivar Differences Associated With Mealiness, Diane R. Mccomber, Harry T. Horner, Mark A. Chamberlin, David F. Cox

Botany Publication and Papers

Russet Burbank, Norchip, Pontiac, and LaSoda potato cultivars were examined for the parameters mealy and waxy. Russet Burbank was judged dry, hard and particulate, typifying mealiness. Using phase contrast microscopy and scanning electron microscopy, raw mealy cells were determined to be larger and more irregularly shaped than cells from waxy cultivars. Mealy cooked cells were engorged with gelatinized starch, cell walls were more polarized, and cell shapes were better retained after mashing, when compared to waxy cells. NMR-T2 bound water readings from Russet Burbank and Pontiac samples did not differ from each other. Starch granule sizes and shapes varied by ...

Semiclassical Quantization Of A Nonintegrable System: Pushing The Fourier Method Into The Chaotic Regime, Karl Sohlberg, Randall B. Shirts Nov 1994

Semiclassical Quantization Of A Nonintegrable System: Pushing The Fourier Method Into The Chaotic Regime, Karl Sohlberg, Randall B. Shirts

Faculty Publications

Semiclassical Einstein–Brillouin–Keller (EBK) quantization of the nonintegrable Hénon–Heiles Hamiltonian succeeds using the Fourier transform method of Martens and Ezra. Two innovations are required for this success: (1) the use of tunneling corrected quantizing actions obtained from an approximate, one-dimensional Hamiltonian and (2) exploitation of intermediate-time approximate quasiperiodicity or "vague tori'' wherein the Fourier transform of chaotic motion over 10–100 vibrational periods allows the determination of frequencies and amplitudes which approximate motion during the time interval. Approximate tori, actions, and EBK energy levels are then straightforward. We use an interpolation method to smooth over small resonance zones ...

A Ceepes Evaluation Of Sustainable Agricultural Policies For Iowa's Msea Site, Walnut Creek, P. G. Lakshminarayan, Aziz Bouzaher, Stanley R. Johnson

CARD Working Papers

Contamination of the Nation's ground and surface water supplies from normal use of pesticides and fertilizers has caused growing concern about the impact of agricultural practices on water quality. Informed decisions on sustainable agricultural policies to protect soil and water quality, and also to minimize economic stress to the producers, requires integrated economic and environmental research designed to study the complex interaction of soils, weather, hydrology, chemicals, economics, and other farm management factors. The concept of studying the effects of current and emerging agricultural practices in relation to soil, weather, and management was initiated within five key Midwest sites ...
