Are Happy People Ethical People? Evidence from North America and Europe
(2004-07)
We examine empirically the relationship between happiness and the ethical decisions of individuals. We use data from the 1995-97 wave of the World Values Survey (WVS) to test the hypothesis that the relationship between ...
The water quality assessment and biodiversity of phytoplankton in Phayao Lake, Phayao Province, Thailand
(University of Missouri, College of Agriculture, Food and Natural Resources, 2022)
The goals of this evaluation of Phayao Lake were to evaluate the physical, chemical, and biological water quality, to determine the phytoplankton biodiversity, and to examine the relationship between biodiversity and water quality. Seven stations...
Simultaneous Diffusion of Herbicide Resistant Cotton and Conservation Tillage
(AgBioForum, 2009)
This study used state-level data from 1997-2002 to econometrically estimate factors explaining the diffusion of two technologies by US cotton producers: herbicide-resistant (HR) cotton seed varieties and conservation ...
Multi-scale synthesis of historical fire regimes along the south-central US prairie-forest border
(SpringerOpen, 2019)
Background: Along the prairie-forest border in the south-central USA exists one of the most extensive areas of uncut forest in the nation ([greater than]323 750 hectares), providing unique potential for developing multi-century ...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This study performed a content analysis of agricultural print media coverage of dicamba herbicide. Issues from eight publications published over 33 months were included...
Characteristics of Herbicides and Weed-Management Programs Most Important to Corn, Cotton, and Soybean Growers
(AgBioForum, 2009)
The introduction and rapid adoption of herbicide-tolerant crops has renewed interest in better understanding the characteristics of herbicides and weed-management programs that are important to growers besides profitability. ...
Effects of Weed-Resistance Concerns and Resistance-Management Practices on the Value of Roundup Ready[trademark] Crops
(AgBioForum, 2009)
This study estimates grower benefits of Roundup-Ready[trademark] (RR) weed management programs and how weed-resistance concerns and resistance-management practices affect those benefits. Direct survey methods were used to ...
An evaluation of pre- and post-timber harvest water quality in low-order streams in the Missouri Ozarks
(University of Missouri--Columbia, 2009)
Missouri Department of Conservation's (MDC) best management practices (BMPs) for Regenerative Oak Clear Cutting (ROCC) practice was evaluated on effectiveness to preserve downstream water quality. Fifteen sites, located on MDC lands in Shannon...
A test of differential GPS correction methods at Fort Huachuca, Arizona
(University of Missouri--Columbia, 2009)
