Assessing red wolf conservation based on analyses of habitat suitability and human perception of carnivores
(University of Missouri--Columbia, 2018)The red wolf (Canis rufus) is a critically endangered species endemic to the southeastern United States. Currently the world's only wild population resides in a single locale on the Albemarle Peninsula in northeastern North ... -
Association between positive emotion regulation strategies and the reward positivity
(University of Missouri--Columbia, 2018)Emotion regulation dysfunction is a core feature of Major Depressive Disorder (MDD). Recently, research has begun to focus on positive emotion regulation strategies such as dampening and savoring of positive emotion. ... -
Characterization of agroforestry feedstocks and their biochars and their effects on soil greenhouse gas emissions in a floodplain soil
(University of Missouri--Columbia, 2018)The temperature at which biochar (biocharcoal) is produced is a major factor that determines its chemical and structural characteristics. The objectives of this research were to assess the effects of feedstock source among ... -
Characterizing hormesis and the in vitro effects of sub-lethal fungicide exposure in sclerotinia homoeocarpa
(University of Missouri--Columbia, 2018)Dollar spot, caused by Sclerotinia homoeocarpa F.T. Bennett, is the most economically important disease of turfgrass. Dollar spot reduces aesthetics and playability of turfgrass, and when left uncontrolled can result in ... -
Children's evaluation of everyday social encounters questionnaire -- short form validation
(University of Missouri--Columbia, 2018)The main goal of the current study was to validate a short form of the Children's Evaluation of Everyday Social Encounters Questionnaire (ChEESE-Q). In order to do this, we administered a two-vignette version of the ChEESE-Q ... -
Contactless extraction of respiratory rate from depth and thermal sensors
(University of Missouri--Columbia, 2018)Monitoring of respiration and restless sleep can help detect sleep disturbances that may be indicative of poor health and functional deficits. The current methods of estimating the respiratory rate such as Pneumograph, ... -
Deep learning bandgaps of topologically doped graphene
(University of Missouri--Columbia, 2018)Manipulation of physical and chemical properties of materials via precise doping affords an extensive range of tunable phenomena to explore. Recent advance shows that in the atomic and nano scales topological states of ... -
Deepnet : an extensible data acquisition and curation framework supporting computer vision deep learning research
(University of Missouri--Columbia, 2018)We present a system, DeepNet, for ingestion, curation, and management of geospatial data images to facilitate a range of geospatial research. The system allows for the semi-autonomous ingestion of geospatial data from a ... -
Design and simulation of automatic tape winding system
(University of Missouri--Columbia, 2018)Based on two-axis manual tape winding machine, this paper describes and developes 3-axis automatic tape winding system. Beginning with motor analysis, discussion on the relationship between motors torque, angular velocity ... -
Determining electrofishing response thresholds of smallmouth bass (micropterus dolomieu), flathead catfish (pylodictus olivaris), and blue catfish (ictalurus furcatus)
(University of Missouri--Columbia, 2018)We examined the response to electrofishing of three Missouri sportfish: Smallmouth Bass, Blue Catfish, and Flathead Catfish. We had three objectives for this research effort: 1) determine the effective conductivity of each ... -
Direct from sample phenotypic antibiotic susceptibility testing
(University of Missouri--Columbia, 2018)To transition from broad-spectrum antibiotic therapy to a more effective "targeted" therapy, i.e. in order to determine whether the infecting strain is resistant or susceptible to individual candidate antibiotics, clinicians ... -
Direct-from-sputum rapid phenotypic drug susceptibility test for mycobacteria
(University of Missouri--Columbia, 2018)The spread of multi-drug resistant tuberculosis (MDR-TB) is a leading global public-health challenge. Because not all biological-mechanisms of resistance are known, culture-based (phenotypic) drug-susceptibility testing ... -
Effect of preovulatory estradiol and(or) postovulatory progesterone on the establishment of pregnancy in beef cattle
(University of Missouri--Columbia, 2018)Preovulatory secretion of estradiol and postovulatory secretion of progesterone are essential for preparing the uterine environment for pregnancy in cattle. In a previous study, circulating concentrations of preovulatory ... -
ENSO and PDO-related variability in South Pacific circulation patterns and seasonal range prediction for Bolivia in South America
(University of Missouri--Columbia, 2018)Seasonal range prediction over North America has been based on intraseasonal and interannual variability related to the Pacific North America (PNA) pattern and El Nino and Southern Oscillation (ENSO), respectively. These ... -
Evaluating progestin-based protocols to control estrous cycles of beef heifers prior to timed artificial insemination
(University of Missouri--Columbia, 2018)The recent development of split-time artificial insemination as a breeding strategy improved reproductive outcomes following treatment with the 14d CIDR[copyright]-PG protocol; however, STAI has not been evaluated with ... -
Evaluation and development of first order fire effects mortality model predictions for eastern hardwood forests
(University of Missouri--Columbia, 2018)The First Order Fire Effects Model (FOFEM) is a useful tool for predicting fire-induced mortality in western coniferous forests. However, it lacks robust models for eastern hardwood species. Managers in the eastern United ... -
Evaluation of a solid-liquid manure separation operation
(University of Missouri--Columbia, 2018)Field monitoring and laboratory tests were conducted to evaluate the efficacy and practicality of a solid-liquid separation barn for finishing pigs. The solid-liquid separation system included a mechanical scraper and ... -
Evaluation of stress in concrete using ultrasonic waves
(University of Missouri--Columbia, 2018)This research investigates the use of ultrasonic waves to evaluate the stress and damage in concrete. Tests were conducted on 6 in. x 6 in. x 12 in. plain concrete specimens (f'c = 6,000psi) at different loading stages ... -
Generation Z perceptions of product placement in original Netflix content
(University of Missouri--Columbia, 2018)By 2019, $11.44 billion is predicted to be spent in the U.S. on product placement, a dramatic increase from the $4.75 billion spent in 2012 (Statista, Product). A 2016 survey revealed that among the general population in ... -
Habitat selection and movement by spotted bass and shorthead redhorse downstream of a hydropeaking dam in Missouri
(University of Missouri--Columbia, 2018)Flow alteration caused by hydropeaking dams may disrupt the natural flow regime and impact physical habitat and biological community, thus threatening the health of freshwater ecosystems. Life history strategies of fish ...
