Mercury Exchange Between The Atmosphere And Low Mercury Containing Substrates, Mae Sexauer Gustin, Mark Engle, Jody Ericksen, Seth N. Lyman, Jelena Stamenkovic, Mei Xin

USU Uintah Basin Faculty Publications

Mercury is emitted to the air from Hg-enriched and low Hg-containing (natural background) substrates. Emitted Hg can be geogenic, or can be derived from the re-emission of Hg that was previously deposited to the soil from the atmosphere. Atmospheric Hg can be derived from natural and/or anthropogenic sources and can be deposited by wet or dry processes. It is important to understand the relative magnitude of emission, deposition, and re-emission of Hg associated with terrestrial ecosystems with natural background soil Hg concentrations because these landscapes cover large terrestrial surface areas. This information is also important for developing biogeochemical mass balances, …

Development Of Pcr-Based Chloroplast Dna Markers That Characterize Domesticated Cowpea (Vigna Unguiculata Ssp. Unguiculata Var. Unguiculata) And Highlight Its Crop-Weed Complex, Y. Feleke, R. S. Pasquet, P. Gepts

All Peer-Reviewed Publications

In 1992, Vaillancourt and Weeden discovered a very important mutation for studying cowpea evolution and domestication. A loss of a BamHI restriction site in chloroplast DNA characterized all domesticated accessions and a few wild (Vigna unguiculata ssp. unguiculata var. spontanea) accessions. In order to screen a larger number of accessions, primers were designed to check this mutation using PCR RFLP or direct PCR methods. Using these new primers, 54 domesticated cowpea accessions and 130 accessions from the wild progenitor were screened. The absence of haplotype 0 was confirmed within domesticated accessions, including primitive landraces from cultivar-groups Biflora and Textilis, suggesting …

All Peer-Reviewed Publications

The stemborers Chilo partellus and Busseola fusca are major pests of subsistence cereal farming in Africa. Volatiles released by two cultivated hosts, sorghum and maize (Sorghum bicolor and Zea mays), and two wild grass hosts, Pennisetum purpureum and Hyparrhenia tamba, were collected by air entrainment. Electrophysiologically active components in these samples were detected by coupled gas chromatography-electroantennography (GC-EAG), and the active peaks identified by gas chromatography-mass spectrometry. A total of 41 compounds were identified from the four plant species, all of which, as well as two unidentified compounds, elicited an electrophysiological response from one or both of the stemborers. The …

All Peer-Reviewed Publications

Background: For remote identification of mosquito habitats the first step is often to construct a discrete tessellation of the region. In applications where complex geometries do not need to be represented such as urban habitats, regular orthogonal grids are constructed in GIS and overlaid on satellite images. However, rice land vector mosquito aquatic habitats are rarely uniform in space or character. An orthogonal grid overlaid on satellite data of rice-land areas may fail to capture physical or man-made structures, i.e paddies, canals, berms at these habitats. Unlike an orthogonal grid, digitizing each habitat converts a polygon into a grid cell, …

Effect Of Staged Practices And Motivational Climate On Goal Orientation And Sportsmanship In Community Youth Sport Experiences, Mary Sara Wells, Gary D. Ellis, Skye G. Arthur-Banning, Mark F. Roark Oct 2006

Effect Of Staged Practices And Motivational Climate On Goal Orientation And Sportsmanship In Community Youth Sport Experiences, Mary Sara Wells, Gary D. Ellis, Skye G. Arthur-Banning, Mark F. Roark

Kinesiology and Health Science Faculty Publications

Significant acts of poor sportsmanship and aggression are becoming increasingly prevalent in youth sports. Youth who have negative experiences as a result of witnessing or being directly involved in such poor sportsmanship experiences are less likely to participate in future sport activities, thereby contributing to sedentary lifestyles and a number of health related problems. Goal orientation theory provides a basis for understanding why many of these unsporting acts may occur. “Task-oriented” participants focus on their intra-individual growth and development in sports and tend to be much less involved in aggression and poor sportsmanship. In contrast, “Egooriented” participants judge success in …

Effects Of Irrigation And Mowing On Species Diversity Of Grass And Wildflower Mixtures For The Intermountain West, Daniel W. Dewey, Paul G. Johnson, Roger Kjelgren Sep 2006

Effects Of Irrigation And Mowing On Species Diversity Of Grass And Wildflower Mixtures For The Intermountain West, Daniel W. Dewey, Paul G. Johnson, Roger Kjelgren

Plants, Soils, and Climate Faculty Publications

Grass and wildflower mixtures can be aesthetically appealing, water-conserving, low-maintenance alternatives to conventional turfgrass. One problem with these mixtures is loss of species diversity over time. We examined the effects of irrigation and mowing on the species diversity of 3 grass and wild-flower mixtures. The nonirrigated and non-mowed treatment combination maintained diversity most effectively whereas the irrigated and mowed treatment combination was least effective. Generally, when the irrigation treatment was significant (P < 0.05), irrigated plots contained more wildflowers. When the mowing treatment was significant (P < 0.05), mowed plots contained more common yarrow (Achillea millefolium L. [Asteraceae]) and strawberry clover (Trifolium fragiferum L. [Fabaceae]) and fewer Pacific aster (Symphyotrichum chilense (Nees) Nesom [Asteraceae]). Height measurements on non-mowed plots showed that irrigated plots had taller canopies than nonirrigated plots. Common yarrow was the most competitive wildflower, followed by strawberry clover and Pacific aster. Mixture 3 containing crested wheatgrass (Agropyron cristatum (L.) Gaertn. [Poaceae]) and thickspike wheatgrass (Elymus lanceolatus (Scribn. & J.G. Sm.) Gould ssp. lanceolatus [Poaceae]) maintained species diversity for the longest duration under nonirrigated and non-mowed conditions.

Enterprise Resource Planning Productivity Function:The Impact Of Ceo Holdings And Horizon And Implementation Characteristics, Husain Yousef Alyousef Sep 2006

Enterprise Resource Planning Productivity Function:The Impact Of Ceo Holdings And Horizon And Implementation Characteristics, Husain Yousef Alyousef

Accounting Dissertations - Archive

The productivity of Enterprise Resource Planning (ERP) systems has been discussed in several other studies in the past decade. Those studies utilized several research methodologies, including case studies, surveys and archival data. The results were largely consistent with the theoretical predictions that ERP implementation enhances firm productivity. The only exceptions were the results of studies that were conducted using financial archival data as a measure of productivity. This study predicts that the exceptional findings of the previous studies in the ERP-productivity relationship are due to the failure to consider several important factors: CEO equity holdings and horizon, timing of the …

Corruption And Growth Under Weak Identification, Philip Shaw, Marina-Selini Katsaiti, Marius Jurgilas Sep 2006

Corruption And Growth Under Weak Identification, Philip Shaw, Marina-Selini Katsaiti, Marius Jurgilas

Economics Working Papers

The goal of this paper is to revisit the influential work of Mauro [1995] focusing on the strength of his results under weak identification. He finds a negative impact of corruption on investment and economic growth that appears to be robust to endogeneity when using two-stage least squares (2SLS). Since the inception of Mauro [1995], much literature has focused on 2SLS methods revealing the dangers of estimation and thus inference under weak identification. We reproduce the original results of Mauro [1995] with a high level of confidence and show that the instrument used in the original work is in fact …

Perspectives On Teachers As Digital Library Users: Consumers, Contributors, And Designers, Mimi Recker

Instructional Technology and Learning Sciences Faculty Publications

"...freed of the constraints of physical space and media, digital libraries can be more adaptive and reflective of the communities they serve. They should be collaborative, allowing users to contribute knowledge to the library, either actively through annotations, reviews, and the like, or passively through their patterns of resource use. In addition, they should be contextual, expressing the expanding web of inter-relationships and layers of knowledge that extend among selected primary resources. In this manner, the core of the digital library should be an evolving information base, weaving together professional selection and the 'wisdom of crowds.'" (Lagoze, Krafft, Payette, & …
