Nonclassical correlation of polarization-entangled photons in a biexciton-exciton cascade
Das, Sumanta
Agarwal, G. S.
We develop a theoretical model to study the intensity–intensity correlation of polarization-entangled photons emitted in a biexciton–exciton cascade. We calculate the degree of correlation and show how polarization correlations are affected by the presence of dephasing and energy-level splitting of the excitonic states. Our theoretical calculations are in agreement with the recent observation of polarization-dependent intensity–intensity correlations from a single semiconductor quantum dot (Stevenson et al 2006 Nature 439 179). Our model can be extended to study polarization-entangled photon emission in coupled quantum dot systems.

Analysis of the efficiency of the electric utility industry during the period of 1954-1973
Kositwongsakul, Ngampis
Jackson, James F.
Scope and Method of Study: This report consists of an analysis of the efficiency of the electric utility industry during 1954-1973 in the area related to energy, plant and equipment, profitability performance and solvency. Several models of ratio analysis are developed to measure the efficiency of all investor-owned electric utilities which are available in The Utility Compustat Tape. The results obtained are applied to the industry as a whole.
Findings and Conclusions: The conclusion reached in this study is that the electric utility industry is now having a financial problem. Specifically, the industry will have difficulties in raising sufficient capital because of depressed earnings which can be generally attributed to the inflationary impact on the following areas: (1) high interest, (2) plant and equipment, and (3) fuel. An additional factor is the difficulty in obtaining timely rate increases because of regulatory friction. The financial problems facing the industry are severe .and require public recognition of its need to provide adequate capital funds to meet the growing needs of electricity in the years ahead. The basic solution is to have adequate rate increases that will impress potential investors.

Time resolved synthetic aperture terahertz impulse imaging
McClatchey, K.
Reiten, M. T.
Cheville, R. A.
Using a well characterized terahertz (THz) impulse ranging system we demonstrate broad bandwidth imaging at THz frequencies using an inverse synthetic aperture deconvolution technique. The system demonstrates millimeter and submillimeter resolutions along the cross range and range axes, respectively. The range resolution, determined by the THz pulse bandwidth is 0.12 mm, while the cross range resolution is 1.2 mm; both resolutions agree well with theoretical predictions. Through imaging of cylindrical targets we demonstrate quantitative measurement of target position in the image plane within the experimental error of 0.2 mm. Imaging of geometrically scaled complex targets is demonstrated for a 1:2400 scale model ship (1 mm=24 m) corresponding to a full scale frequency bandwidth of 83 - 625 MHz at a distance of 840 m.

Usefulness of goodwill impairment under SFAS No. 142 in reflecting the relative efficiency of firms
Vichitsarawong, Thanyaluk
Hansen, Don R.
Meek, Gary K.
Nabar, Sandeep
Tilley, Daniel S.
Scope and Method of Study: This study examines goodwill impairment under SFAS No. 142 whether it improves financial reporting quality by better reflecting the underlying relative efficiency of a firm. A firm's relative efficiency is measured by using Data Envelopment Analysis (DEA). The analysis is undertaken on three selected industries--durable manufacturers, computers, and services. First, Wilcoxon rank sum tests are used to compare the efficiency of a firm with other firms in the same industry (the cross-sectional analysis) and with similar firms over different periods (the longitudinal analysis). Second, Tobit and logistic regressions are applied to analyze factors affecting the percentage of goodwill impairment and a decision to report goodwill impairment. Finally, a logistic regression and a multivariate discriminant analysis (MDA) are used to assess the predictive ability of relative efficiency in determining potential goodwill impairment.
Findings and Conclusions: Results of Wilcoxon rank sum tests strongly support the hypothesis that impairment firms are relatively less efficient than non-impairment firms in the year of goodwill impairment reporting. Tobit and logistic regressions provide evidence that lagged relative efficiency of firms is negatively associated with the percentage of goodwill impairment and a decision to report goodwill impairment, after controlling for managerial reporting incentives. The inferences are robust to the choice of various input/output variables in the DEA model. The results suggest that the relative efficiency is an important determinant of goodwill impairment. Finally, results of logistic regressions used to assess the predictive ability of relative efficiency indicate that measures of relative efficiency can be used to identify the likelihood of goodwill impairment. The MDA models including relative efficiency measures correctly predict more than 50 percent of the actual impairment. These findings provide opportunity for future research to include a measure of firm overall performance in the prediction model. Overall, goodwill impairment under SFAS No. 142 can reflect the decline in relative efficiency of firms, thereby achieving the FASB's objective.

Relationship of Trust, Parental and Peer Support Relationships, and Health Risk Behaviors in College Students
Reese-Taylor, LaMeshia Sheri
Jacobs, Sue C.
Croff, Julie M.
McGaha-Garnett, Valerie
The scope of this study was limited to students at Oklahoma State University who chose to participate. The purpose was to examine the relationship of trust, parental and peer support relationships, and health risk behaviors. Participants answered questions about 4 areas of high risk health behaviors, trust, and support. A sample of 172 students (one-third graduate students) volunteered to participate. Pearson correlations were used to examine the associations among trust, the perceived adequacy of support received from parents and peers, and engagement in high risk health behaviors. In additional analyses, Independent sample t-tests and ANOVAs were used to examine differences in trust and perceived support between those who engaged in high risk behaviors and those who did not for the total sample and undergraduates only. There was a positive relationship between trust and the adequacy of perceived support received from family and friends. There was not a relationship between engagement in high risk health behaviors and trust or adequacy of perceived support. However, for undergraduate students, there was a significant difference between those who engaged in heavy episodic drinking and those who did not and perceived support from family and friends.

Negotiating a curriculum balance: Perceptions of special education teachers and administrators regarding alternate assessments in Oklahoma
Modenbach, Joy Lynn
Brown, Pamela
Davis, C. Robert
Harris, Ed
Bailey, Lucy
Ramsey, Jon
This qualitative study sought to understand how teachers and administrators navigate the state and federal requirements for students with severe and profound disabilities in regards to alternate standards and assessments. Special education teachers must balance the required curriculum while continuing to meet the physical and emotional needs of students with severe and profound disabilities. Seven special education teachers and three administrators were interviewed individually in non-school settings, usually coffee shops. Teachers and administrators work diligently each day to support the students and meet their academic, social, emotional and physical needs.
During the research and data collection phases of this study the stories that emerged illuminated the daily dedication, compassion, and perseverance of the teachers. The researcher used a constructivist perspective and Ethic of Care theory (Noddings, 2006) to analyze data. Data analysis revealed emergent themes including: frustration, unreasonable expectations, balance of competing expectations, time balance, assistive technology and oppression and Othering.
Teachers feel pulled between following the state and federal requirements while also meeting the needs of the students they serve. The alternate standards and assessments often do not fully inform the teacher or parent regarding the process the student is making because the standards and assessments are unachievable to the student being assessed. Implications include the need for providing more training for teachers aligned to the assessment and standards with a continuum of specific strategies for each standard allowing teachers to better balance the planned curriculum with the functional level of each student and changing the expectation from a competitive structure to tracking individual progress.

Experimental Investigation of Drag Reduction on Automobiles with an Inflatable Boat-Tail
McNamara, Kathleen

There is a growing demand for higher efficiency and more environmentally friendly vehicles, including better fuel economy, reduction in wind noise level, and greater vehicle performance and dynamic stability. These factors vary with aerodynamic performance. Overall, aerodynamic drag contributes to as much as 60% of a vehicles fuel consumption, motivating vehicle manufacturers to investigate new drag reduction applications. When streamlining a vehicle for aerodynamic performance, one method is by boat-tailing, or rear end tapering. This study includes an investigation of the overall potential of a lightweight yet rigid, inflatable drag reduction device, applied to a motor vehicle. Based on original concepts proposed by Toyota Research Institute North American (TRINA), combined with past research of inflatable technology, an inflatable drag reduction device is designed, manufactured, and tested. Peel strength of adhesive bonds testing provides detailed results of proper heat-sealable fabric utilization, and preferred materials are selected for inflatable models. Through multiple concept considerations and varying design stages ergonomic boat-tail designs evolve, as does construction, and manufacturing details are included. The inflatable boat-tail as a drag reduction device is examined through wind tunnel testing at Reynolds numbers O(10^5) by 2D wake survey and conservation of momentum theory, and multiple system designs are compared. Results show 10-80% decreased drag coefficients as a function of varying boat-tail construction compared to a baseline model. Wake survey is also performed at multiple heights along boat-tail sections, and 3D effects are investigated. Further investigations include wake survey velocity profiles as a function of angle of attack. Standard deviation and velocity fluctuations are compared for individual systems, and results are discussed.

Genistein Reduces Production of Proinflammatory Molecules in Human Chondrocytes
Hooshmand-yazdi, Shirin
Arjmandi, Bahram H.
Lucas, Edralin A.
Madihally, Sundar V.
Previously, we reported that cartilage is an estrogen receptor (ER) positive tissue and that mRNA levels of ER increase in postmenopausal women with osteoarthritis. Based on our findings and those of other investigators, we hypothesized that local rather than circulating estrogen levels negatively affect chondrocyte metabolism and that selective estrogen receptor modulators (SERM) augment cartilage health. To test the latter part of our hypothesis, we explored the role of genistein, a naturally occurring SERM with high affinity to bind ER, in inhibiting the lipopolysaccharide (LPS)-stimulated cyclooxygenase (COX)-2 but not COX-1 in human chondrocytes (HCH). Cells (PromoCell, Germany) were treated with three levels of genistein (0, 50, and 100 ?M). After one hour, the genistein-treated cells were stimulated by one μg/mL LPS for six hours. Cells were then harvested and the cytosolic fraction was isolated for assessing COX-1 and COX-2 protein levels using Western blot technique. Nitric oxide (NO), interleukin-I Beta (IL-1?), and YKL-40 productions were also measured in cell culture supernatants. NO, and IL-1? were measured as markers of inflammation and YKL-40 was assessed as a marker of cartilage catabolism. Interestingly, LG50 was more effective in reducing NO production than LG100 (42% vs. 28%) in comparison with LPS-treatred control cells. Genistein had no significant effect on either YKL-40 or IL-1? levels. Our data indicate that the LPS-stimulated increases in COX-2 protein level and NO in supernatant are reduced by pretreatment of genistein, whereas COX-1 protein level is not affected by genistein.

This is the author manuscript of an article whose final version has been published in Psychological Assessment, American Psychological Association, December 2014.
We examined the longitudinal measurement properties and predictive utility of the Center for Epidemiologic Studies Depression Scale (CES-D) from early to late adolescence among a sample of North American Indigenous youths. Participants were 632 North American Indigenous adolescents (n = 632; 50.3% girls; M age at baseline = 11.11 years) participating in an 8-year, 8-wave longitudinal study. Via in-person interviews, participants completed the CES-D at Waves 1, 3, 5, and 7, and the major depressive disorder (MDD) module of the Diagnostic Interview Schedule for Children at Waves 1, 4, 6, and 8. Confirmatory factor analyses indicated that responses to the CES-D were similarly explained by 2-, 3-,and 4-factor models, as well as a 1-factor model with correlations between the error variances for the positively worded items. Longitudinal measurement equivalence analyses indicated full structural (i.e., factor structure), metric (i.e., factor loadings), and scalar (i.e., observed item intercepts) equivalence for each factor structure. Substantive analyses showed that the CES-D was significantly associated with MDD both concurrently and prospectively, although these effects were smaller than might be expected. Finally, the CES-D negative affect and somatic complaints subscales were the strongest and most consistent predictors of MDD. Among our sample of North American Indigenous youths, the measurement properties of the CES-D were stable from early to late adolescence. Moreover, somatic difficulties and depressed affect were the strongest predictors of MDD.

Effect of attentional control on the relationship between worry and stress responding
Frosio, Kristen Elizabeth
Grant, DeMond M.
Byrd-Craven, Jennifer
Wells, Tony T.
Malone, Chad
Worry is a form of negative perseverative thinking and a maladaptive cognitive emotion regulation strategy associated with multiple forms of psychopathology (Nolen-Hoeksema & Watkins, 2011; Cisler et al., 2010). Perseverative worry may be exacerbated by deficits in attentional control (Armstrong et al., 2011). Attentional control is the ability to voluntarily shift and disengage attention while utilizing cognitive resources selectively to inhibit the processing of extraneous or irrelevant stimuli (Derryberry & Reed, 2002; Friedman & Miyake, 2004). Current influential theories propose that individuals high in attentional control are able to use attention to regulate their emotions (Oschner & Gross, 2008). However, low attentional control may be a cognitive vulnerability factor for developing pathological forms of anxiety due to a broad failure to deploy regulatory processes that directly influence changes in physiological stress responding (Armstrong et al., 2011). The current study evaluated whether trait attentional control mediated the relationship between trait worry and cortisol stress response after a psychosocial stressor. Participants (N=95) completed several self-report measures, the Trier Social Stress Test, and provided three saliva samples to measure cortisol stress response throughout the experiment. Results indicated that attentional control did not mediate the relationship between trait worry and cortisol stress response. However, exploratory analyses revealed that attentional control did moderate the relationship between cortisol stress response and self-reported acute worry during the stress recovery phase. Specifically, at low levels of attentional control, decreases in cortisol stress response predicted increases in acute worry levels post-stressor. These findings point toward alternative cognitive control measures better explaining the relationship between trait worry and cortisol stress responding (e.g. working memory, attentional biases). These findings also point toward attentional control potentially impacting the relationship between worry and physiological responses to stress. Specifically, worry may contribute to alterations in attentional control and stress, only to perpetuate enhanced negative feedback sensitivity of the HPA-axis and maintain the cycle of cortisol dysregulation-but only at low levels of attentional control.

Single Versus Dual Pesticide Applications for Increasing Oklahoma Winter Wheat Grain Yield and Profitability
Watson, Branden H.
Edwards, Jeff
Hunger, Robert Marvin
Royer, Tom
Marburger, David A.
Foliar fungicides and insecticides can be useful tools in management decisions against fungal diseases and insect pests of winter wheat in Oklahoma, but little is known about multiple applications and tank-mixes of these pesticides. Two studies were conducted across three different locations during the 2016-2017 and 2017-2018 growing seasons, focusing on multiple fungicide treatments and fungicide + insecticide treatments at two different timings, Feekes 6 (jointing) and Feekes 9 (full flag leaf emergence). Two wheat varieties were used in each study, chosen based on susceptibility and resistance to fungal diseases. In the first study which assessed a dual fungicide application approach compared to a single application, results showed that a dual fungicide application can reduce disease levels, protect more yield potential, and provide greater marginal return than a single fungicide application. However, this management practice was highly dependent on variety and location. Due to the timing of disease occurrence in most cases during the course of the study, a single fungicide application was more often profitable than the dual application approach. The second study examined the effect of fungicide + insecticide tank-mix applications compared to each pesticide applied alone at both growth stages. Results for this study showed that a fungicide + insecticide application can provide greater yield than each pesticide applied alone. However, this result was highly dependent on the year, location, and timing when fungal diseases and/or insects were present, and it only occurred at the Feekes 6 application timing. Greater marginal return from a fungicide + insecticide application compared to each pesticide applied alone was also dependent on year and location. This greater marginal return from the fungicide + insecticide application was observed at both Feekes 6 and Feekes 9 but occurred at the Feekes 6 application timing the majority of the time. Based on the results of these two studies, scouting for fungal diseases and insects and understanding wheat variety susceptibility to fungal diseases should dictate whether multiple fungicide applications and/or fungicide + insecticide tank-mixes should be used instead of making prophylactic applications in Oklahoma.

Larval Hemolymph Proteins and Physiological Role of Prophenoloxidases in Anopheles Gambiae
He, Xuesong
Jiang, Haobo
Noden, Bruce
Soulages, Jos� Luis
The African mosquito Anopheles gambiae is one of the major vectors for human malaria. Understanding its immune system may provide new means for disrupting the disease transmission. While the Drosophila melanogaster and Manduca sexta immune systems are well studied, most components ofthe mosquito system remain to be examined. Insect hemolymph contains important factors for humoral and cellular defense responses as well as immune signal transduction, including pattern recognition receptors, serine proteases, serpins, antimicrobial peptides. In the present study, we collected hemolymph samples from water- and E. coli-pricked A. gambiae larvae. The samples were separated on SDS-PAGE and subjected to LC-MS/MS analysis. The detected peptides were searched against A. gambiae proteins from VectorBase. We have identified a total of 1,756 proteins.Most of the abundant proteins contain putative signal peptides. Twenty-five most abundant proteins represent over half of the total protein amount, 109 proteins are up-regulated, 49 are down-regulated, and 235 are considered to be defense-related. After examining the protein distribution in the gel slices, we found that more abundant proteins tend to exist in more of the slices. We also obtained evidence for proteolysis, post-translational modification, serpin-protease complex formation, and high Mr immune complex formation based on the distribution data. In addition to the proteomic study, we generated monoclonal antibodies against prophenoloxidases PPO2 and PPO7 and found that PPO2 is presented in the adult hemolymph. Lastly, we tried to knockdown PPO gene expression in female adults by injecting double-stranded RNA and examined their survival following an E. coli challenge. No significant difference was observed between the test and control groups.

Proposed general shop program on the junior high school level in the Attucks Separate School, Ponca City, Oklahoma
Hunter, Zebedee
Hill, Cary L.
Statement of Problem: The scope of the problem is to formulate a desirable industrial arts program on a junior high school level in a general shop program in the Attucks Separate School in Ponca City that will help boys and girls find themselves.
Methods of Procedure: The results of this study are based primarily on material studied on industrial arts in junior high schools of Oklahoma in Industrial Arts Education 572. Further library study has included current literature, periodicals, and books pertaining to junior high schools, and to industrial arts in the general shop in particular. The writer has also visited several junior high schools over the state, and discussed general shops as to organization. This was done in order to make the study more complete.
Findings and Conclusions: Industrial arts in the junior high schools are changing constantly; only much slower at present than they have in the past, because it is a fact that most of the imperfections have been worked out. However, just as junior high schools began to operate smoothly, the school populations increased and the senior high schools introduced a general shop program which more or less disturbed the junior high school industrial arts program. This junior high school industrial arts course must be flexible and exploratory. After several conferences with the Attucks School principal and state department officials, it was decided that the following courses should be offered in grades seven, eight, and nine: (1) applied drawing, (2) woodworking, (3) elementary electricity, (4) leathercraft and shoe repair, and (5) home mechanics for girls.

Near-instant g-function construction with artificial neural networks
Dusseault, Bernard
Pasquier, Philippe
IGSHPA Research Track (2018)
A g-function is a useful tool that simplifies the calculations of heat exchanges in a ground-coupled heat pump system. In this work, we show how an artificial neural network can be trained to construct a g-function with high efficiency and reliability. First, we show how a block matrix formulation can be used to construct rapidly a g-function. This method is then used to assemble a database of 27,000 g-functions with a variety of input parameters. This database of g-functions is used to train a feed-forward neural network having three hidden layers using the back-propagation algorithm to update the weights and biases of the neurons. The network we developed in this work can estimate the long-term g-function of a ground heat exchanger made of 1 to 10 boreholes over a duration of 100 years with various ground thermal properties, borehole field configurations, length and buried depth in a few milliseconds. The contribution of this work is to lay out the methodology to allow anyone to construct a g-function with an artificial neural network.

Impact of mandrel support on core Ec
Gerhardt, T. D.
Rykard, D.
Yang, Y.
International Conference on Web Handling (2001)
Over the past 15 years, Sonoco has conducted solid mechanics research focused on structural behavior of spirally wound, paper tubes. The scope of this program has included experimental, numerical, and analytical mechanics approaches as documented in references (1-9). As is well known from published winding models, core outside diameter stiffness (Ec) is incorporated into the analysis through a boundary condition. We have previously published proper Ec values for paper tubes (4) and, at the last OSU International Web Handling Conference, described a method to experimentally measure Ec (9). However, all published Ec data was collected on cores that were supported on the ends, but had minimal radial support in the test zone. In the field, many winding processes utilize an expandable mandrel that supports the core along its entire length. Our recent research suggests that these support conditions can have a significant impact stiffening the core wall and increasing Ec. As Ec is changed, expected stresses in the wound roll are altered. In this paper, we describe a new experimental method capable of measuring Ec data for cores supported by mandrels found in some field applications. To collect this data, we modified the test device described at the last conference. We also present a Finite Element model that quantifies core stiffening from mandrel support.

Daly
Nelson, Kendall

Claxton, Ray
The Daly was a project that my professor and I came up with for my honors thesis. I wanted to create something golf related; maybe brand a golf tournament or create a golf company. My professor wanted me to take a different angle on the branding because he thought it might push me to design a different way. After much collaboration, we decided I would brand a golf tournament around rock and roll! The Daly is a made up golf tournament that has rock and roll concerts every night, is loud and obnoxious, and really everything golf is not. That was the challenge my teacher wanted me to tackle: taking two opposing things and making them work together.

Developing a Gluten, Soy, Dairy, and Nut Free Energy Bar with a Suggested Haccp Plan
Altoaimi, Bayan
Bowser, Timothy
Mcglynn, William
Payton, Mark
The purpose of energy bars is to provide people with energy to help them perform various tasks in their lives in a better way. There are several types of energy bars in the market nowadays; however, there are some people who are allergic to gluten, nut, soy, and dairy and, unfortunately, there is no energy bar that can suit their needs. As a result, this study attempted to develop an energy bar that is gluten, nut, soy, and dairy free. A comparison between the developed energy bar in this study and a commercial bar was made. Sixty-six panelists were recruited from students, faculty and staff on contract of Oklahoma State University and were voluntarily participated in the study. They were asked to taste the two samples and evaluate eight important attributes including stickiness to touch, color, chewiness, flavor, sweetness, adhesiveness to teeth, texture and overall acceptance using a nine-point hedonic scale. Proximate analysis of both samples was determined. A suggested HACCP plan for industries intend to produce this energy bar was proposed. Results indicated that there was a significance difference (p<0.05) in chewiness, adhesiveness to teeth, and stickiness between the developed energy bar and the commercial bar. No difference was found in the remaining quality attributes. The developed energy bar was higher in carbohydrate and moisture and lower in protein, ash, and fat comparing to the commercial bar. In addition, the HACCP plan had one CCP that could be overcome using an X-ray detection system.

AIChE National Student Design Competition: Modular distributed ammonia synthesis, Group 9
Barber, Rylee
The preliminary design of an anhydrous ammonia plant was performed. In the United States, the Corn Belt is the largest consumer of anhydrous ammonia fertilizer, yet the Corn Belt obtains most of its fertilizer from the Gulf Coast. The transportation of ammonia fertilizer from the Gulf Coast to the Corn Belt is both costly and hazardous. To mitigate the additional safety and cost burdens associated with transportation of anhydrous ammonia, it is the objective of this project to produce the preliminary design of a plant located in the Minnesota River Valley. The project memo states this location to be especially suited for ammonia production due to its high demand in agricultural use within this region of the United States.
The plant is designed to produce 50 metric tons per day of anhydrous ammonia with a product purity of 99.5% by mass. The reactants utilized to produce anhydrous ammonia can be expensive and hazardous to transport, so it is the objective of this preliminary design to also design onsite production of both hydrogen and nitrogen. The desired purity is 99.9% by mole for both hydrogen and nitrogen.
The design selected to meet these requirements includes a pressure swing adsorption system for nitrogen production, which includes two adsorption towers, three double pipe heat exchangers, and three reciprocating compressors. The steam methane reforming for hydrogen production includes: one packed bed reactor, one membrane reactor, two shell and tube heat exchangers, one reciprocating compressor, one fired heater and two adsorption towers. The Haber-Bosch process was utilized for ammonia production, and includes one packed bed reactor, two shell and tube heat exchangers, three reciprocating compressors, one flash drum, one air cooled heat exchanger, and three storage tanks. Aspen HYSYS was utilized to simulate the process and evaluate methods for optimization.
A safety analysis was performed by examining mistakes that have occurred over the last 50 years in ammonia production that have led to safety issues. By discovering what could go wrong and what has gone wrong in the past, accommodations were made to produce an inherently safer design. Loss of containment was the biggest concern associated with the project resulting in focus throughout the process of mitigating this risk through inherent safety.
An economic analysis has been completed on the design with an expected project life of 20 years. The economic analysis yielded the net present value to be $15,000,000 in 2020 US dollars, and the DCFROR to be 13%. This displays the economic feasibility of the project as the minimum rate of return is 8%. The payback period was found to be approximately 8.3 years, and the breakeven product price was found to be $460. The design team has determined from this analysis that the project is both technically and economically feasible.
A sensitivity analysis was performed to determine the risk associated with the project. The impact of variation of the capital investment, raw material cost, operating cost, and revenue on the net present value and DCFROR were analyzed. Each variable was analyzed at a ±10%, ±20%, and ±30% variation. The variation of revenue had the greatest impact on the project. Through this analysis the team has deemed the risks associated with the project low. This supports the recommendation to move forward to the detailed design phase of the project.

Evaluation of a Position-specific Task in Ncaa Division I Linemen
Hester, Garrett
Jacobson, Bert H.
Smith, Doug B.
O'Brien, Matthew S.
It is the responsibility of the strength and conditioning professional to implement quality training programs and properly evaluate each athlete's physical performance. It is essential that strength and conditioning professionals have access to an evaluative tool that provides a practical, position-specific assessment of playing ability in collegiate linemen. The purpose of this study was two-fold: To compare the performance of a position-specific task on the MAXX Football Sled Device (MFSD) between NCAA Division I offensive and defensive linemen. Also, to investigate any associations among selected strength and power variables with performance on the MFSD in NCAA Division I offensive and defensive linemen. Twenty-six NCAA Division I offensive (n=12) and defensive linemen (n=14) (age 20.11 1.49yrs) performed ten "fire-and-drive" repetitions on the MFSD. Upon an auditory signal rendered from the MFSD, subjects exploded in to the breast plate region of the dummy as forcefully and rapidly as possible. After each repetition subjects reset themselves in a three point stance. Timing between repetitions was an automatically randomized duration of 6 to 10 sec. The MFSD measured average force (AVGF) across the ten trials and movement time (MT), the time from the auditory signal to initial contact on the dummy, for each of the ten repetitions. Secondary data including 1 RM of the squat, bench press, and power clean, along with vertical jump, 10 yd. sprint, 40 yd. sprint, and body fat percentage were gathered from the team's strength and conditioning staff. Defensive linemen were found to produce significantly lower movement times when compared to offensive linemen (p = 0.032). There were no significant relationships found between the dependent variables gathered from the MFSD and any independent variables. Test-retest reliability demonstrated strong reliability with the device for both AVGF (ICC = .813; SEM = 93.4) and MT (ICC = .828; SEM = .022). Results of this study indicate that defensive linemen accelerate out of the three point stance quicker than offensive linemen. Further exploration for the purpose of finding exercises that correlate with a position-specific task in these athletes is warranted.

Examining teacher effectiveness through value-added scores and observed teaching practices
Castro Braun, Amy
Curry, Katherine
Harris, Ed
Self, Mary Jo
Ormsbee, Christine
Value-added assessment is designed to measure teacher contributions to student achievement in order to promote effective teaching (Battelle for Kids, 2011b; Darling-Hammond et al., 2012; Lee, 2011). When value-added assessment is used, research indicates that in some cases effective teaching is promoted, but in other cases it is not (Amrein-Beardsley & Collins, 2012; Darling-Hammond et al., 2012; Betebenner et al., 2012; McCaffrey & Hamilton, 2007; Quattrochi & Chapman, 2010). One reason that effective teaching may not be promoted is value-added models are not specifically designed to be diagnostic tools of effective teaching (Betebenner et al., 2012; Darling-Hammond, et al., 2012; Goe, 2008; RAND Corporation, 2004). Empirical evidence about which specific teaching practices improve student learning is lacking and additional research is needed (Goe, 2008; RAND Corporation, 2004; Stronge, Ward, & Grant, 2011).
The purpose of this study was to examine the relationship between value-added scores for elementary, junior high, and high school teachers of English/language arts, reading, and/or math in a large suburban Oklahoma public school district and administrators’ ratings of their specific teaching practices as measured by the Tulsa Model for Observation and Evaluation. There were small, positive correlations that were statistically significant for all teachers between overall value-added scores and overall evaluation scores on the Tulsa Model rubric for both school years. This result indicates that higher ratings of effective teaching were slightly associated with higher overall value-added scores and increased student achievement levels for this sample. Only two of the Tulsa Model rubric domains – classroom management and instructional effectiveness – had statistically significant relationships with value-added scores. This is attributed to the student-focused nature of these domains in contrast to the professional growth, interpersonal skills, and leadership domains. The specific teaching practices of effective teachers in the areas of Preparation, Discipline, Modeling, Monitoring, and Adjusts Based Upon Monitoring were linked to increased value-added scores.

Mercury Contamination in Freshwater Turtles of Eastern Oklahoma: Evaluation of Non-destructive Sampling Techniques
Powell, Alisha L.
Belden, Jason B.
Bidwell, Joseph R.
Fox, Stanley
Recent studies in Oklahoma have found levels of mercury (Hg) contamination in fish that exceed safe consumption limits in several lakes. This study investigates the degree of Hg pollution in aquatic turtle species of Oklahoma that are used most commonly for human consumption. Turtles have been used as monitors of chemical contaminants in aquatic environments in both freshwater and marine habitats routinely. These studies are often complicated by the requirement to sacrifice long–lived and slowly reproducing species. A need for a nonlethal routine monitoring technique has been recognized due to a decline in turtle populations. Spiny softshell (Apalone spinifera), common snapping turtle (Chelydra serpentina), and red eared slider (Trachemys scripta) are the most commonly harvested turtles in Oklahoma and thus the indicator species chosen for analysis. Multiple tissue types (muscle, liver, claw, and scute) were collected from 72 turtles in eastern Oklahoma during the summers of 2010 and 2011 from 10 water bodies. Softshells had the highest Hg concentrations (0.04–0.72 mg kg−1), followed by snapping turtles (0.03–0.30 mg kg−1) and red eared sliders (0.01–0.20 mg kg−1). Based on the USEPA food consumption guidelines, seven of the ten sites had average Hg concentrations warranting consumption limits for at least one species. Average muscle Hg concentrations among sites were significantly different (p<0.01). No significant relationships were found between Hg burden and size, sex, or age. Liver/muscle ratios indicated current contamination. In addition, claw and scute were removed from each turtle to test the validity of using non–destructive (external) tissues as an alternative to lethal/destructive sampling of muscle and liver. Claw was the best overall predictor for muscle Hg burdens when comparing across species (R2=0.79) with similar slopes between hard and softshell turtles (slopes=0.087 and 0.099). Scute was not as reliable when all species were combined (R2=0.41). However, when turtles were separated between hard and softshelled species, relationships between Hg concentrations in scute correlated well with concentrations found in muscle (R2=0.84 and 0.83). Continuous monitoring programs are recommended to further protect human health and to track changes in contamination levels. These programs can be completed using the non–destructive tissue techniques and the corresponding linear regression models formulated here.

Oscar Ameringer and American Socialism
Hazlett, O. James
Hale, Douglas
Agnew, Theodore L.
Jewsbury, George F.
This study analyzes the ideology of Oscar Ameringer, one of the Midwest's noted socialists. While the immediate goal of the study is to determine whether Ameringer fits into a left-wing category instead of a right-wing one, it also provides an opportunity to view American radicalism from the perspective of a German immigrant who devoted his life to bringing about socialism in the -United States. The nature of radicalism in the West remains little studied, and Ameringer's perspective is another view from which to understand it better. Also Ameringer continued to view American radicalism from a European viewpoint, which added a different perspective than many of his colleagues.

Analizing Risk in the Restaurant Industry
Ceschini, Silvio
Kim, Woody
Jerrold, Leong
Ryan Bill
The objectives of the study are twofold. It first aims to examine whether systematic risk is influenced and predicted by certain financial variables in the overall U.S. restaurant industry, and it sets out to determine which variables better explain the systematic risk. Second, it intends to investigate how those financial variables affect the systematic risk with regards to the quick-service and the full-service segments. The financial variables utilized were profitability, leverage, efficiency, liquidity, growth, and size. For the overall restaurant industry, profitability was found to be the most significant variable and negatively related to systematic risk. The second significant variable was leverage, positively related to systematic risk. The third significant variable was liquidity; it was positively related to systematic risk. By comparing the quick and full-service segments, profitability was statistically significant in both segments. Leverage was found to be significant in the quick-service segment.

Aspiring Entrepreneurs from Kenya, South Africa, and Uganda: New Media Use and Cultural Perceptions
Maroney, Brentney
Cartmell, Dwayne
Sitton, Shelly
Edwards, Craig
The population for this study was the 12 emerging entrepreneurs from the countries of Kenya, South Africa and Uganda who were part of an Entrepreneur Fellows� two-way exchange program. The study assessed perceptions of the Entrepreneur Fellows� regarding new media platforms prior to the program, following the program, the culture of the United States, the benefits and challenges of participating in an international internship/job shadowing experience, and the training experiences that resonated with the Fellows� regarding their professional roles. A mixed methods analysis was used to examine the phenomenon prior to the program and the post program interview. Based on the questionnaire, the Fellows� preferred Facebook and Pinterest the most, but the Fellows had never heard of the Pinterest and Flickr platforms. Based on the interviews, the Fellows� gained a better understanding of the possibilities of new media outlets but faced the challenges of cost, as well as availability and lack of knowledge in their enterprises. While in the United States, the Fellows had an overall positive opinion of the program and were grateful for their internship placements. The Fellows� traveled back to Africa empowered by the project with beliefs they could make a difference in their countries, especially in regard to empowering aspiring entrepreneurs for economic success.

Acoustic and Netting Surveys of Western Ozark Highlands Bats with Habitat Suitability Models for Three Threatened and Endangered Species
Ritchie, Anna Rachel
McBee, Karen
Papes, Monica
Bolek, Matthew
Bats in the United States and Canada are experiencing major population declines because of white-nose syndrome (WNS), a fungal disease that kills bats hibernating in caves. First discovered in New York in 2006, WNS has rapidly spread south and west across the United States. Camp Gruber Training Center (CGTC) is a United States National Guard training facility in Muskogee County, Oklahoma. Muskogee County is adjacent to three counties that are suspect for WNS infection as of 2017. I performed acoustic and mist net surveys at CGTC to determine composition of the chiropteran community of the area and if bats in Muskogee County have been exposed to WNS by looking for characteristic damage on wing membranes. Acoustic and mist net surveys determined that the bat community of CGTC is likely dominated by non-endangered species that have not suffered high mortality from white-nose syndrome (Nycticeius humeralis and Lasiurus borealis). There are at least 2 species that occur rarely within CGTC that are federally endangered (Myotis grisescens and Myotis sodalis) that, along with the non-endangered Perimyotis subflavus, have been known to contract WNS. I found no evidence of WNS symptoms on the bats of CGTC as of summer 2017. I used maximum entropy species distribution modeling (Maxent) to create habitat suitability models for three species that occur in the Ozark Highlands around CGTC, Myotis grisescens (endangered), M. septentrionalis (threatened), and M. sodalis (endangered). These models help explain the community composition of CGTC by revealing habitat preferences of these species and may suggest future range expansions or possible locations of unknown colonies for all three species. I also found that M. septentrionalis and M. sodalis are highly similar in their habitat preferences, supporting the United States Fish and Wildlife Service decision to combine summer survey guidelines for these species.

Access to tricyclic heteroarenes by an iodine-promoted cyclization reaction
Crittell, Rachel
Bolliger, Jeanne
Fennell, Christopher
For many years, investigations on nitrogenous heterocycles have been an essential part of organic chemistry due to their widespread use in medications. Our research examines alternative ways to prepare nitrogen-containing heteroarenes while minimizing the formation of unwanted by-products. Many of our target molecules have structural similarities with biologically active compounds that are commonly used for numerous conditions, such as cancer, anxiety, and fungal infections. By optimizing a preliminary procedure from the Bolliger lab, we were able to improve the isolated yields for the iodine-promoted cyclization step. In this presentation, we will discuss the results of our cyclization reaction and discuss possible reaction mechanisms. Ultimately, we hope our research will pave a pathway to novel species with biologically relevant functional groups.

Gender goggles: Does candidate gender impact viewer perception of negativity in campaign advertisements?
Welch, Leigh
Mendez, Jeanette
Coe, Brooke
Political campaign advertisements are a common staple for current campaign efforts, and negative advertisements in particular are a popular campaign tool. It is evident both male and female candidates often attempt to win elections by tearing down opponents through the use of negative campaign advertisements. What is unclear is whether viewers perceive the message a candidate presents to be more or less negative based on the gender of the candidate sponsoring the ad, and where the perception of negativity in an ad impacts candidate favorability. An experimental study was conducted to determine if a candidate’s gender impacts the viewer’s perception of message negativity. A political advertisement was written and filmed once with a male candidate, and once with a female candidate. This advertisement was shown to separate groups who were then asked to complete a questionnaire regarding the treatment they were exposed to. Findings show that there are significant results that show a correlation between certain perceived message tones and gender of the candidate. Additionally, there were interesting results regarding candidate favorability.

Investigations of a Precast Bridge Deck System
Investigations of a precast bridge deck system
Ghashgesh, Mostafa Farhat
Ley, M. Tyler
Russell, Bruce W.
Emerson, Robert N.
Good, J. Keith
Scope and Method of Study:
Improved methods of bridge deck construction are greatly needed. Bridge decks are often the first element to require repair or replacement because of its direct exposure to the elements and tire wear. This dissertation presents a new precast overhang system that allows for significant improvements in construction speed, economy, and safety while meeting the AASHTO requirements and providing a serviceable structure. Welded rebar mats were also investigated to replace tied reinforcing bars with partial depth panels to improve the economy, constructability, and construction speed of bridge decks. Bridge decks have been constructed and tested that have used tied reinforcing and welded rebar mats. A self-written non-linear finite element program was created to model the tested specimens and provide an alternative, economic, and time-saving tool. Strut-and-tie modeling as well as design provisions of three design codes were also used to predict failure loads.
Findings and Conclusions:
Satisfactory results were obtained, which indicate that the system will allow a support beam to be removed in certain circumstances. The improved ability of the wire mat to help resist cracking could allow an owner either greater construction tolerances for the reinforcement placement or improved crack control and hence long term durability. The proposed FE program has proven successful at modeling the performance of concrete bridge decks with interior and overhang loading. For these specimens it was found that a shear reduction factor β of 0.20 showed the best correlation with the experimental data. Additionally, it is found that the STM is the closest, in estimating failure loads and predicting the failure sequence and mode as well. FIP design recommendation was found the closest to experiments. Furthermore, it satisfactorily estimated the failure modes experimentally observed in all specimens.

Comparison of sequential analyses generated from an enlarging data base. a case study in ground water contamination
Powell, Leonard Allen
During my studies of hydrogeology, the question of how much information is truly needed for a dependable analysis of a ground water situation was often brought up. The saying "90% of the information comes from 10% of the data," was presented several times in an almost axiomatical sense. This quote, offered by Dr. Wayne Pettyjohn, served as the basic topic of this thesis. Special thanks go to Dr. Pettyjohn, who served as chairman for my thesis committee. His advice and the data obtained from him made this thesis possible.

Assessing the Bond Quality of Pre-Stressing Strands with SCC Using NASP Test
Purkait, Saugata
Russell, Bruce Wayne
Emerson, Robert
Jeong, David
Important research in durability of self consolidating concrete structures dates back to 1980 in Japan. The lack of standardized test procedures, performance data and current design application uncertainty to members made with SCC had limited its acceptance in U.S despite of its increased use in Japan, Canada and Europe. SCC has drawn attention in pre-stressed industry due to benefit in enhancing construction productivity. Despite the interest in SCC and rapid development of SCC technology, its widespread use is restrained somewhat by the material and structural performance concerns, including the issue of bond. This thesis highlights effects of SCC on the bond performance of pre-stressing strands. The Standard Test for Bond (also called the North American Strand Producers Bond Test) was performed to evaluate the effect of 0.5 in strand with various SCC mixtures. Research variables include coarse aggregate content and sizes with a fixed rate of HRWRA and VMA. From these test, the pull out values are used to determine whether SCC causes a change in the bond strength of pre-stressing strand. With this, the effects of SCC proportions on the bond properties can be evaluated.

Laboratory Investigations of the Mechanisms of Groundwater Seepage Erosion and Piping in Cohesive Soils
Felice, Rachel Gayle
Fox, Garey
Wilson, Glenn
Bulut, Rifat
Seepage and soil piping are two mechanisms that can cause streambank erosion and failure. Groundwater seepage can cause erosion either by undercutting or "pop-out" failure. The objective of the seepage study was to utilize a constant-head soil box packed with sandy loam soils at prescribed bulk densities (1.30-1.70 Mg m-3) and an outflow face at 90. Bulk density controlled the mechanism of seepage erosion/failure. For both soils, tension failures occurred at densities less than 1.60 Mg m-3 and undercutting was observed for densities 1.60 Mg m-3 or greater. Data from experiments was used to calibrate SEEP/W to determine pore-water pressures. SLOPE/W utilized the pore-water pressures to determine stability. SLOPE/W only incorporates pore-water pressure effects in factor of safety calculations; therefore, the model was unsuccessful at predicting a failure. Seepage gradient forces may play a more prominent role in streambank and hillslope instability, and this mechanism should be incorporated into stability models. In addition, soil pipe experiments were conducted and flow and internal erosion data were derived for two soils packed at uniform bulk densities but different initial moisture contents. Soils included were clay loam (Dry Creek) and sandy loam (Cow Creek). Initial gravimetric moisture contents (MC) were 10, 12 and 14% for Dry Creek soil and 8, 12, and 14% for Cow Creek soil. A 1-cm diameter rod created the horizontal pipe. A constant head was maintained; flow rates and sediment concentrations were measured from the pipe outlet. Submerged jet erosion tests (JETs) derived erodibility parameters. Flow rates from the box experiments calibrated the deterministic model. The influence of the initial MC of the packed soil was apparent with some pipes (8% MC) expanding so fast that limited data was collected. The deterministic model estimated equivalent flow rates, but had difficulty matching observed sediment concentrations when pipes rapidly expanded by internal erosion. The submerged JETs predicted similar erodibility coefficients compared to the deterministic model for the more erodible cases (8 and 12% MC), but not for the less erodible cases (14% MC).

Evaluation of Catch Kids Club After School Program: a Nutrition and Physical Fitness Intervention for Thrid, Fourth, and Fifth Grade Students
Rumph, Mary Katherine
Hildebrand, Deana
Betts, Nancy M.
Shriver, Lenka Humenikova
The objective of this study was to evaluate the impact of CATCH Kids Club after school which focused on improving nutrition knowledge, attitude, intent, self-efficacy, behavioral capability, and behavior, and also focused on improving physical fitness among third, fourth, and fifth grade students. Additionally, Oklahoma Core Curriculum standardized test scores were evaluated to see if students participating in regular physical activity performed better. Intervention (n = 160) and control (n = 163) school sites were part of the Lawton Public School System. Nutritional knowledge, attitude, intent, self-efficacy, behavioral capability, and behaviors were measured by a questionnaire administered to students. Physical fitness was measured by curl-up, flexed-arm hang, sit and reach, and PACER cardiovascular test using the Cooper Institute's Fitnessgram protocol. Data was collected by the Physical Education, and Wellness Coordinator for the Lawton Public School District and then submitted to Oklahoma State University for analysis. Chi-square goodness-of-fit, one-way ANOVA, and paired t-tests were utilized to evaluate student responses between control and intervention groups at pre and post, and evaluate intervention students' responses from pre to post. Findings of this study indicated students that participated in CATCH Kids Club had improved nutrition knowledge, intent, and behaviors from pre to post intervention. Also, intervention students demonstrated improved cardio endurance from pre to post intervention. Overall, CATCH Kids Club was effective in eliciting positive nutrition and physical activity changes among students.

The objective of this study is to determine if SMA mixtures have better rutting performance than S-4 mixes made with the same PG grade of binder. Different SMA and S-4 mixtures were collected from different parts of Oklahoma. All mixtures were made with PG 76-28 asphalt cement. To evaluate the performance properties of the mixtures, samples were made and tested for Hamburg rutting resistance using the Hamburg rut tester. Generally, SMA mixes have been shown to perform better with respect to rutting resistance than S-4 mixes. SMA mixes showed lower average rut depth than S-4 mixes.

Selecting among alternative production functions, effect of lime cost on optimal nitrogen levels and vertical integration in the West African cotton sector
Tumusiime, Emmanuel
Brorsen, B. Wade
Epplin, Francis
Biermacher, Jon
Vitale, Jeffrey
Zhang, Hailin
Scope and Method of Study:
This dissertation consists of three essays: The first essay determines the optimal level of N fertilizer for rye-ryegrass pasture using yield functions estimated with different functional forms that assume parameters are either nonstochastic or stochastic. Three yield functions were estimated: linear response plateau, quadratic, and Spillman-Mitscherlich.
The second paper determines the effect of considering the cost of lime on recommendations about optimal levels of N. Yield response and soil pH change functions were estimated and used to determine the optimal levels of N and lime. The study also developed a new version of a linear response plateau function that allows the yield plateau to vary by year with respect to nitrogen but not soil pH.
The third paper provides an economic explanation of the existence of parastatal vertical integration market structures in the cotton sector of West Africa, and contrasts it with other market structure alternatives in terms of welfare and sector efficiency.
Findings and Conclusions:
In the first essay, nonstochastic models are rejected in favor of stochastic parameter models. The stochastic models lead to smaller recommended levels of N, but the economic benefits of using fully stochastic models are small since expected profit functions are relatively flat for the stochastic models.
In the second essay, considering the cost of lime reduced the optimal level of N by as much as 11.3%. Acidification potential due to N fertilizer increased nonlinearly as N rate increased. N acidification appears to be more severe with N application rates above consumptive potential of the crop than with N that is used by the plant.
In the third essay, due to credit and or factor market constraints, vertical integrated cotton parastatals increase sector welfare and efficiency by supplying inputs to overcome credit constraints. Surplus sharing between the grower and the integrator is significantly shifted towards the cotton company. Removing the integrated cotton parastatals in favor of a free market structures would result in little cotton being produced.
