Nitrogen management for climate change mitigation in the southern Great Plains
(2014-12)
Nitrous oxide (N2O) is a potent greenhouse gas (GHG), with a global warming potential 310 times that of carbon dioxide (CO2). Agricultural soil management in the U.S. is responsible for 69% of N2O emissions. Fertilizer ...
Influence of vegetation height on the dispersal of house flies (Musca domestica) from livestock facilities and filth fly activity associated with composted and non-composted beef cadavers
(2014-07)
House flies, Musca domestica L., are well known pests inexorably linked to livestock operations, and they also serve as mechanical vectors of various human pathogens including E. coli 0157:H7. Changes in the landscape from ...
Three essays: Switchgrass yield prediction; biomass harvesting cooperative; and Oklahoma grain infrastructure replacement
(2014-05)
The first essay estimates switchgrass yields in Oklahoma using average temperature and total rainfall during summer months. The fitted model agrees well with available yield data and the estimated yields were consistent ...
Another missing link in the service profit chain: Composite self-regulation as a mediator
(2014-12)
The service profit chain contends that service-related human resource practices and management influence service behavior, performance, and ultimately organizational performance. This study builds upon recent work implicating ...
Implications of pyric-herbivory on central North American grassland ecology, management and production
(2014-07)
The interaction of fire and grazing is an ecological process regulating fire-dependent ecosystems. Prior to European settlement, grasslands were regulated by fires and focal grazing by herbivores (pyric-herbivory), a ...
Validating forensic tools for crop biosecurity: Case study investigation of salmon blotch of onions in Israel
(2014-07)
Globalization of agricultural commerce increases the vulnerability of the United States to introductions of plant pathogens by inadvertent or intentional means. Plant pathogen forensics combines traditional plant pathology ...
Educational identity formation and transformations: Life-history analysis of first-generation, adult college students
(2014-07)
The purpose of this qualitative research was to explore how educational identities were formed and transformed within educational institutions over the lifespan and how the identities were related to decisions about ...
Effect of classroom management strategies on math fluency growth rate
(2014-05)
A classroom management intervention consisting of providing effective commands and behavior-specific praise statements was implemented in four first-grade general education classrooms. The effects of this intervention on ...
Simultaneous confidence intervals using the restricted Scheffe method and sequential testing procedures for single-step methods
(2014-05)
Multiple comparison problems arise when a set of inferences are considered simultaneously. When a separate inference approach is used to answer multiple related questions, it can cause many false positives and lead to ...
Quantitative structure-property relationship generalized activity coefficient models
(2014-05)
Phase behavior properties of chemical species and their mixtures are essential to design chemical processes involving multiple phases. Thermodynamic models are used in phase equilibria calculations to determine properties, ...
