ABA has demonstrated utility with a number of populations. One population that has had limited research devoted toward them is neurotypical adults. While there is much research on job satisfaction and what causes employees to be unhappy (mostly miscommunication), there is little research that explores what can be done to change the lack of satisfaction in the workplace. Through surveys designed to assess a variety of participants’ levels of expressive language and psychological flexibility, this study aims to determine if there are statistically signification relationships between expressive language abilities, psychological flexibility, and job satisfaction. This study found that there are statistically significant, positive correlations between job satisfaction, relational responding rates, and psychological flexibility. Additionally, this study explores potential treatment and trainings to combat employee dissatisfaction in the workplace.

One of the degradation processes of zirconium-based nuclear fuel assemblies is irradiation-induced growth, an anisotropic, stress-independent, macroscopic deformation mechanism that elongates fuel cladding tubes axially. Irradiation-induced growth is driven by the irradiation-induced formation of dislocation loops, where the evolution of the loop structure can be complex, with the initial formation of loop generating transient growth, while the later formation of component dislocation loops, or loops, leads to accelerated growth. A full mechanistic understanding of loop nucleation is as yet unforthcoming. This thesis utilizes the diffraction peak broadening analysis software, named extended Convolutional Multiple Whole Profile, to study the dislocation structure evolution of neutron- and proton-irradiated zirconium alloys in order to validate proton-irradiation as a effective tool for the study of irradiation damage in relation to irradiation-induced growth. The diffraction profiles obtained exhibit unexpected features present in the tails of the Bragg peaks, tentatively attributed here to either strained regions of matrix, or diffuse scattering from severely distorted regions around nucleating precipitates, both originating from an increased solute concentration. The diffraction results indicate that the proton-irradiated samples exhibit qualitatively similar behaviours as seen from neutron-irradiation, such as a threshold irradiation dose before the formation of loops, however, a continued increase of loop dislocation density determined from peak broadening analysis is not observed by transmission electron microscopy. It is also shown that the Nb-containing Low-Sn ZIRLO® alloy has a lower dislocation density than the Nb-free Zircaloy-2 after the formation of loops correlating well with the relative irradiation-induced growth behaviours observed in- reactor. A correlation between a reduction in the loop dislocation density and the formation of loops is observed in Low-Sn ZIRLO® and Zr-1.60Sn-0.033Fe, providing support for the hypothesis that vacancy loops transform into loops. Zr- 0.61Sn-0.024Fe and Zr-1.60Sn-0.033Fe alloys show a rapid increase in the loop dislocation density in the initial stages of proton-irradiation, likely due to the low irradiation-resistance of the precipitates present in these alloys.

The present study sought to examine the use of two teaching procedures as methods of increasing relational responding in children with developmental disabilities. We compared one procedure that presented test probes for combinatory entailment and transformation of function probes throughout the acquisition of directly trained A-B and B-C relations. In the second procedure test probes were withheld until the learner achieved mastery criteria for the directly trained A-B and B-C relations. Results show that all three participants achieved mastery criterion across both procedures and demonstrated the emergence of mutual entailment, combinatory entailment, and transformation of stimulus function. The presentation of entailed and transformation probes resulted in faster acquisition of directly trained and test relations. An account of current research and implications of these findings is provided.

"The intent of this Thesis is to study the potential of distributed resources to increase the efficacy of the electric system without decreasing the efficiency of the system. Distributed resources (DR) are technologies that provide an increase in power or a decrease in load on the distribution system. An example of DR is a storage device that uses electricity during low use periods to store energy and then converts the stored energy to power during high use periods. The energy storage being studied is for the purpose of peak shaving or the ability to shift small amounts of load to a more optimum time. In particular the concept of load curve leveling is explored. DR options are studied to determine how size, location, and storage losses impact the overall system efficacy and efficiency. This includes impacts on system losses, capacity utilization, and energy costs."

abstract: The lifetime of a transformer is essentially determined by the life of its insulation system which is a time function of the temperature defined by its thermal class. A large quantity of studies and international standards have been published indicating the possibility of increasing the thermal class of cellulose based materials when immersed in natural esters which are superior to traditional mineral oils. Thus, a transformer having thermally upgraded Kraft paper and natural ester dielectric fluid can be classified as a high temperature insulation system. Such a transformer can also operate at temperatures 20C higher than its mineral oil equivalent, holding additional loading capability without losing life expectancy. This thesis focuses on evaluating the use of this feature as an additional capability for enhancing the loadability and/or extending the life of the distribution transformers for the Phoenix based utility - SRP using FR3 brand natural ester dielectric fluid. Initially, different transformer design options to use this additional loadability are compared allowing utilities to select an optimal FR3 filled transformer design for their application. Yearlong load profiles for SRP distribution transformers, sized conventionally on peak load demands, are analyzed for their oil temperatures, winding temperatures and loss of insulation life. It is observed that these load profiles can be classified into two types: 1) Type-1 profiles with high peak and high average loads, and 2) Type-2 profiles with comparatively low peak and low average load. For the Type 1 load profiles, use of FR3 natural ester fluid with the same nominal rating showed 7.4 times longer life expectation. For the Type 2 load profiles, a new way of sizing ester filled transformers based on both average and peak load, instead of only peak load, called “Sustainable Peak Loading” showed smaller size transformers can handle the same yearly peak loads while maintaining superior insulation lifespan. It is additionally possible to have reduction in the total energy dissipation over the year. A net present value cost savings up to US$1200 per transformer quantifying benefits of the life extension and the total ownership cost savings up to 30% for sustainable peak loading showed SRP distribution transformers can gain substantial economic savings when the distribution transformer fleet is replaced with FR3 ester filled units. / Dissertation/Thesis / Envirotemp FR3 Fluid Brochure / Envirotempe FR3 Fluid Data Sheet / Masters Thesis Electrical Engineering 2018

Geologic mapping (1:24,000 scale) of the Ice Cave Peak quadrangle, Uintah and Duchesne Counties, Utah has produced a better understanding of the geologic structures present in the quadrangle and has increased our understanding of faulting in northeastern Utah. Map units in the quadrangle range in age from late Neoproterozoic to Quaternary and include good exposures of Paleozoic rocks (Mississippian to Permian), limited exposures of Mesozoic rocks, and good exposures of Tertiary strata (Duchesne River Formation and Bishop Conglomerate) deposited during uplift of the Uinta Mountains. Lower Mississippian strata along the south flank of the Uinta Mountains have typically been mapped as Madison Limestone. Our preliminary mapping suggested that the Madison could perhaps be subdivided into an upper unit equivalent to the Deseret Limestone, and a lower unit separated by a phosphatic interval equivalent to the Delle Phosphatic Member of the Deseret Limestone found farther west. Upon further investigation, we propose not extending the use of Deseret Limestone, with the equivalent to the Delle Phosphatic Member at its base, into the south-central Uinta Mountains. Microprobe analysis revealed no phosphorus in thin sections of this unit. Instead, the unit is composed almost entirely of calcite and dolomite. A zone of northwest-trending faults, called the Deep Creek fault zone, occurs mainly east of the Ice Cave Peak quadrangle. However, our mapping shows that this fault zone extends into the quadrangle. These faults are both strike-slip and normal/oblique faults as documented by mapping and kinematic indicators and cut the folded hanging-wall sedimentary rocks above the Uinta Basin-Mountain boundary thrust fault. These faults may be part of an en echelon fault system that is rooted in the Neoproterozoic and reactivated during Laramide deformation above a possible transfer zone between segments of the buried boundary thrust.

The foundation for osteoporosis risk is established during the time periods of childhood, adolescence, and young adulthood, periods of development when bone mass is being accrued rapidly. The relative quantity of bone mass accrued is influenced by both lifestyle and genetic factors. The purpose of this dissertation project was to discover single nucleotide polymorphisms (SNPs) associated with: (1) The rate of hip bone accrual (measured as bone mineral content or BMC) during the adolescent growth spurt, and (2) Total hip bone mass measured as BMC around the age of 19 when the amount of bone accrued is approximately at its peak. Additionally, SNP × longitudinal lifestyle factor (calcium intake per day, vitamin D intake per day, and minutes of moderate to vigorous physical activity (MVPA) per day) multiplicative interaction effects were assessed. Each cohort member’s vector of longitudinal physical activity measurements was summarized as belonging to one of a set of specific trajectory groups using finite mixture modeling. The same was then done for calcium intake and vitamin D intake. The source of the data utilized was the Iowa Bone Development Study (IBDS), which includes genetic and longitudinal bone measurement information. To discover SNPs, a genome-wide association study (GWAS) design was utilized. Females and males were analyzed separately and together. The association between SNPs and the rate of hip bone accrual during the adolescent growth spurt was assessed using linear mixed models controlling for body size, and the association between SNPs and peak hip bone mass was assessed using an ordinary linear regression model, also controlling for body size. Approximately 500,000 SNPs were tested in each GWA analysis; significance was assessed at a familywise error rate of 0.05, the individual test cutoff of which was determined by using SimpleM, a modified Šídák correction. No statistically significant SNPs were detected at the 0.05 familywise error rate threshold established by SimpleM (p < 1.76×10-7); however genes near suggestive SNPs (24 total) were assessed for biological relevance. Of most biological relevance were two suggestive SNPs (rs2051756 and rs2866908, p-values of 1.25×10-6 and 4.28×10-6, respectively) that were detected in an intron of the DKK2 gene through the GWA analysis exploring peak bone mass in females. The DKK2 gene is part of the Wnt signaling pathway and is associated with embryonic development; additionally, it is expressed more highly in osteoarthritic osteoblasts than in normal osteoblasts. No statistically significant results were found from the SNP × lifestyle factor multiplicative interaction effect tests. The potential importance of the DKK2 gene to peak hip bone mass accrual in females should be studied further in order to understand the pathophysiology of this suggested novel association identified during a discovery GWA analysis.

Accelerometers are devices that have been recently used to assess the performance of weightlifters in training. This case study used vertical acceleration data to assess multiple snatch attempts in a single lifter during a training session. The lifter exhibited variability in a number of measures, including peak acceleration and peak velocity. The measures calculated from the acceleration-time data did not show consistent trends between made and missed lifts. More work is needed identify variables of interest for snatch performance.

A detailed study was made of the James Peak-Sharp Mountain area, in the southern part of the Bear River Range, Utah. The mapped area is located in north-central Utah between lat. 41°22'30" N. and lat. 41°30' N. and long. 111°42'30" W. and long. 111°46' W. It measures about 3.8 miles in the east-west direction and 8.7 miles in the north-south direction. The area is centered about 22 miles south-southeast of Logan, Utah. Stratigraphic units of late Precambrian to Mississippian age underlie the mapped area. The Precambrian units include the Mutual and Browns Hole Formations. The Brigham, Langston, Ute, Blacksmith, Bloomington, Nounan, and St. Charles Formations make up a complete Cambrian section. The Ordovician Garden City and Swan Peak Formations, the Ordovician-Silurian Laketown Formation, the Devonian Water Canyon and Hyrum Formations, and the Mississippian Lodgepole and Humbug Formations overlie the St. Charles in normal succession. The oldest unit the Precambrian Mutual Formation, crops out in the southern part of the area on the eastern side of James Peak. The rock units are progressively younger toward the northern part of the area. Mesozoic rocks are not present. The Salt Lake Formation of Tertiary age directly overlies the Paleozoic rocks. The main structural feature of the area is an asymmetrical north-south-trending anticline. The eastern flank dips more steeply than the western flank. The anticline plunges gently north and dies out southward. This anticline is one of a series of asymmetrical anticlines, all steeper on the east than on the west, that includes the Strawberry Valley anticline to the east and the anticline exposed in upper Wolf Creek Canyon to the west. The late Precambrian and early Paleozoic formations, which dip northeast on the eastern flank of James Peak, make up the northeastern flank of the anticline exposed in upper Wolf Creek Canyon. The early Paleozoic to Devonian formations that form Sharp Mountain and dip gently west make up the western flank of the Strawberry Valley anticline. Low-angle thrust faults have disrupted the Precambrian and Paleozoic formations on the eastern and southeastern flanks of James Peak. Displacement on the thrust fault north of upper Wellsville Creek is about 2,000 feet. Movement was generally from the west. Normal faults have disrupted the Paleozoic and Tertiary formations along the eastern margin of Cache Valley and the Paleozoic formations east of McKenzie Mountain. Displacement is indeterminate along the eastern margin of Cache Valley. Maximum displacement, east of McKenzie Mountain, is about 1,750 feet. The normal faults truncate the folds and thrust faults. The folds and thrust faults were formed during the Laramide orogeny. The normal faults were formed during Basin and Range normal faulting. Basin and Range normal faulting is active at the present time.
