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.

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.

Our interactions with letterforms are ever-increasing with the additions of new technologies and a more digitally connected society. Through stone tablets to papyrus scrolls, printed books to digital publishing, type finds new ways to reach our eyes. From the moment we wake up to the numbers and letters on our alarm clocks until the credits roll on the last show we watch before turning off the television to go to bed, typography follows us through nearly every moment of our day. Some instances maintain the formality of strict typographic usage while others exhibit an informality (although no less communicative) that feels almost primal. The way people interact with letterforms is constantly evolving, and typographers need to actively engage in exploring new approaches to type design and typesetting. This body of work serves as evidence of my human experience and the processes and methods of its creation serve as evidence of potential in future directions in letterform design. While many working designers spend their professional days filling boxes with text, this work has been more inspired by designers who have disregarded the box, placed their box on the side of a subway car or used the box to chop text into pieces and start anew. Editorial designer David Carson, artist Augustine Kofie, and letterpress abstractionist David Wolske have all influenced my thesis work. Carson's approach to communication opened a path to more creative exploration in how typography can be used to greater effect by breaking rules than by following them. Kofie's letterform inspires geometric shapes showed me that even the simplest of forms are capable of a powerful and dynamic aesthetic. Finally, Wolske's approach to utilizing older technologies in new ways demonstrated to me that there is much to be explored and drawn out of even the oldest of design tools.As designing type has migrated to the digital realm over the last several decades, type designers have lost a physical connection to their work. In addition, letterforms and type systems have been constrained to the limitations of software and display systems. In order to bring letterform creation back into the hands of the designer, both literally and figuratively, I used a laser engraving machine to create a system of modular wood pieces with a wide variety of straight edges, curves, and diagonals that can be placed on a base in the bed of a cylinder letterpress. This modular system allows me to physically construct letterforms in the same environment in which they will be applied. The tangible artifacts that I created and interacted with over and over again taught me about the nature of certain materials and the wants and needs of inanimate objects. The act of creating all of these pieces of dissected letterforms that I could work with in the physical space of the press bed allowed me to gain a much closer relationship with and understanding of letterform design than I feel I could have gained behind the barriers of a digital screen and keyboard. Although the pieces of the system were initially designed to work on a specific grid ratio, experimentation proved the ability to vary both the ratio and scale of the pieces. This allowed for greater variety and fostered creativity in the letterform design process. This project spans the full cycle of deconstruction to creation. Beginning with the examination of the existing typographic landscape and the current practices in type design, I transitioned into exploration of how shapes form into symbols that can communicate information and aesthetic expression. By breaking down letterforms into their most basic geometric shapes I was able to establish a system of physical exploration that not only enables but promotes tangible interaction in the type design process. With the use of the letterpress as the vehicle for output the process has an association with the origins of modern typographic communication built into it, providing context for past and future directions in type design. Through the exhibition of the body of work in the environment in which it was created, I was able to demonstrate the mechanics of the system, the flexible nature of the process, and the potential for the final printed work to communicate and engage with society. The thesis project and exhibition were titled Puzzling to address the complexity of visual communication and the exertion over the solution for a new approach to modular type design and typesetting.

There is a great difficulty in how graduate students acclimate to both their student and teaching requirements. Adding to that difficulty, some students are also curious about varying pedagogical techniques. This pioneering research examines the intersection of working as a graduate student, teaching in a coordinated course, and the implementation of inquiry-based learning (IBL). Inquiry-based learning has known benefits, and the amount of research on the topic is growing. However, the researcher found no previous research on the topic of creating an inquiry-based learning course that is coordinated. The idea of using IBL in a coordinated course means that more graduate students have potential to be exposed to different ways of teaching. This study follows three participants that had all taught at the university level previously but were new to teaching using IBL. The coordination of this course meant that class sizes were smaller, room assignments were conducive to group work, graduate students received a workbook to facilitate classroom learning, and they had the aid of an undergraduate learning assistant. Therefore, the graduate students were able to focus on the day-to-day activities in their classroom without having the cited barriers to making this pedagogical change, providing them with psychological safety. After one semester, they all agreed that they would continue using active learning more frequently as they move forward as instructors, but did not acknowledge the barriers that they may face teaching a different course.

Chapter 1 exploits the emergence of two de facto states in Côte d’Ivoire during the 2002-2010 political crisis to examine the effects of export tax reduction on the living standards of cocoa farming households. Combining both spatial and temporal variations in exposure to a set of dichotomous export tax policies, I find that farmers in low export tax districts significantly increased their consumption expenditures relative to farmers in high export tax districts. I also provide evidence that the transmission of border prices to local farmers is a relevant mechanism through which the reduction of trade barriers enhances cocoa farmers’ living standards.
Chapter 2 documents that contemporary political development in Africa is highly associated with the pre-colonial ethnic institutional background of the first national leaders. Using either direct measures of democracy and/or covariates of political participation from anthropological records, I show that the political legacy of the first African heads of states who inherited egalitarian and democratic norms from their ancestors has been autocracy. This statistical relationship is not only robust to an array of control variables including economic, geographic and historical fac- tors, but potential endogeneity concerns that may undermine its validity are also addressed. Finally, exploring the potential mechanisms at play, I provide evidence that the natural resource potential of certain countries may have diverted their first national leaders away from their ancestral institutional heritage.
Chapter 3 shows a strong and positive relationship between the ethnic affiliation of African leaders and satellite nighttime luminosity in the historical homelands of ethnic groups. Using a unique dataset on 630 ethnicities and 86 leaders from 48 African countries, I show that luminosity is on average 75% relatively higher in leaders’ ethnic homelands.

In the second part of the research, three additional mutants, S 128A, H 186A and N187A were characterized in the same manner as the K183 mutant enzymes. The decrease in the activity compared to the wild type enzyme is about 200-fold for the H 186A and N 187A mutant enzymes, but only 12-fold for the S 128A mutant enzyme. Dissociation constant for 6PG from the E:NADP:6PG complex (K6PG) is increased by around 6-fold for both S 128A and H 186A and 16-fold for N 187A. Product inhibition studies by NADPH give a dissociation constant for the E:NADPH complex (Kis) that is increased by 5- to 6-fold for the S 128A and H 186A mutant enzymes at nonsaturating 6PG. No significant change is found in Kis value for the N 187A mutant enzyme. The primary deuterium isotope effects decrease for S 128A and H 186A, and increase in the case of N 187A compared to those of the wild type enzyme. The kinetic data suggest that all of the three enzyme side chains are responsible for binding the substrates, and that both S 128 and H 186 play an important role in the decarboxylation process, while N187 facilitates the hydride transfer step.
6-Phosphogluconate dehydrogenase (6PGDH) catalyzes the reversible oxidative decarboxylation of 6phosphogluconate to ribulose-5-phosphate and CO2 with the concomitant reduction of NADP to NADPH. Site-directed mutagenesis was used to change K183 of sheep liver 6-phosphogluconate dehydrogenase to A, E, H, C, Q, R, and M to probe its possible role as a general base catalyst. Each of the mutant proteins was characterized with respect to its kinetic parameters at pH 7, and the pH dependence of kinetic parameters for the K183R mutant enzyme. The only mutant enzyme that gives a significant amount of catalysis is the K183R mutant. Its activity is decreased by about 3 orders of magnitude, and the general base pK is perturbed to a value greater than pH 9. All other mutant enzymes have rates that are decreased by about 4 orders of magnitude compared to the wild type enzyme. Data are consistent with the general base function of K183.

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.

Memory/Erasure is a volume comprised of largely autobiographical poetry. In the first section, Memory, the work focuses on my interpretation of memories, both familial and personal. The second section, titled Erasure, interprets how the memories in the first section impacted my life and my conception of self. Even though some of the poems in the second section are less autobiographical or more fantastic, they are all reflective of my identity, the pieces of my memory that I have re-imagined or buried. Memory/Erasure began years ago. Pieces of the volume have existed, in one form or another, for nearly five years. The work represents many aspects of my life, growing up Southern Baptist, having a mother who suffers from mental illness, a father who never quite understood me, and being a homosexual man. I believe that all of these elements are highly relatable to the reader, whoever that individual may be. Many of the pieces in the volume are experimental, playing with form and spacing. Poetry, as a genre, continues to grow in new and unexpected ways, and Memory/Erasure represents a fusion of more traditional forms and lines with experimental breaks and spacing. Throughout the work, there are many themes or motifs present. A large number of the poems deal heavily in religious imagery due to my Southern Baptist upbringing. These poems embody much of the struggle I faced when I came out. Another major motif of the work is water. Of course, water has plenty of ties to the Christian faith, including baptism. However, water also represents a catharsis for me, a means by which to collect scattered thoughts, to recover that which has been lost.

The electromagnetic spectrum is a finite resource that has become increasingly crowded as the day-to-day operation of the world has become increasingly reliant on wireless devices. With the growing deployment of the Internet-of-Things (IoT), 5G Networks, and broadband internet systems, the available spectrum for radar applications has been reduced and instances of interference across all device types have increased. To mitigate this problem going forward, devices need to be better able to intelligently access the spectrum based on the presence of other users.
A cognitive radio or radar system functions by using adaptive spectrum sensing to detect existing users in the frequency band and adapt to use ’open’ spectrum bands. To ensure the predictable performance of the system and systems that it shares spectrum with, it must detect new users and adapt without interrupting its operation or interfering with the other users. Because modern communications networks can update their spectrum utilization on a sub-millisecond timescale, the critical detection and adaption phase must operate in real-time.
This work presents an implementation of a fast spectrum sensing (FSS) algo- rithm deployed on the field-programmable gate array (FPGA) of an Ettus USRP software-defined radio. This implementation allows for microsecond scale updates of the environment’s spectrum availability. Unfortunately, this FSS algorithm is limited by its knowledge of the spectrum, which is ever-changing. To help improve the system’s dynamic performance a new adaptive detection algorithm is proposed to replace the static threshold of the first implementation. The new detection algo- rithm is a constant false alarm rate (CFAR) inspired detector which allows a cogni- tive sensor to work in a dynamic environment without a-priori information about the spectrum. Combining the FSS algorithm with dynamic signal detection allows the cognitive radio system to adapt to the ever-changing environment without requiring extensive ’listen before talk’ periods before operation.

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.

The intentional segregation of metropolitan areas in the United States during the twentieth century has resulted in rising health disparities in low-income minorities today. Contemporary medical practices like collecting health data by race and not by socioeconomic status obfuscates the problem. OneÕs geography of opportunity, meaning the opportunities one is afforded based on where you live has direct effects on your prospective health. Low income minorities are faced with greater adverse risk because they are more likely to be found in a double jeopardy situation where they are simultaneously impoverished and living in a bad neighborhood. Additionally, treatment within the healthcare system itself is often times sub-par.

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.

The monograph continues by looking at how these two streams emerge from one single---albeit complex---commitment to a proto-scientific commitment to the observance of nature. It is this consistent, coherent, and widely cast observational activity that forms the basis of the Xenophanean revolution. The fifth chapter is an attempt to demonstrate the continuity between the scientific methodology of Xenophanes and ours today.
Initially the extant fragments relating to Xenophanes' epistemology or theology are translated with a brief commentary when a translation issue is paramount. Then a view of Xenophanes' epistemology is developed, based upon this textual exegesis and two millennia of scholarship. It is argued that Xenophanes is not the empiricist, rationalist, or sceptic that he is sometimes portrayed as being. Rather he best fits the model (indeed a mold he helped create) of a naturalistic fallibilist.
Xenophanes was the first ancient Greek to make explicitly philosophical statements about epistemology. He was also the first Pre-Socratic to attack traditional and popular religion, eventually forming a rudimentary natural theology. This monograph attempts to show the clear connection and mutual dependency of these two streams of thought. In the process of this demonstration, however, it is necessary to give an interpretation of both streams.
The same interpretive enterprise is attempted with his natural theology. A number of misunderstandings of Xenophanes' beliefs are laid aside and a "minimalist" vision of his theological convictions is developed. It is found that Xenophanes is not a committed monotheist, or monist, as has sometimes been taught. His philosophical razor trims excessive adumbrations and speculations, and trims theology of many of its traditional aspects.
In the end Xenophanes appears to be quite influential. This document ends by showing the evident appreciation that Socrates held for this thinker. It was primarily through Socrates that Xenophanes would extend his formidable ideas through centuries of western civilization.

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.

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.

Various econometric models of Taiwan have been constructed since 1964. All of these shared the same common shortcomings. Their periods of annual data were too short to maintain a satisfactory degree of freedom. Their estimators were determined by the ordinary least squares method. The models were highly demand-oriented. The theoretical framework of the models and the effects of exports and imports on economic development were barely discussed.
A disequilibrium model for Taiwan is also constructed for comparison in this study. This model confirms the results of the equilibrium model. Moreover, wage increases significantly reduce labor demand, but stimulate labor supply. The relationship between Taiwan's exports and the U.S. GNP is positive, but negative between the Taiwanese exports and the Japanese GNP.
A new equilibrium model of the Taiwan economy is formulated in this study. The primary objective of this study is to analyze the economy of Taiwan and determine useful policy implications. Another purpose of this study is to eliminate the weaknesses of previous models. In particular the data have been made current in an attempt to enlarge the degree of freedom. In order to take care of the simultaneous bias, the 2SLS and 3SLS methods are applied in the estimation procedure. A dynamic simultaneous model is introduced in which the approaches of IS-LM, AS-AD, multiplier analysis, business cycle, and policy experiments are utilized to enrich the findings.
The Taiwan equilibrium model is capable of predicting turning points and has a very good fit. It takes into account the important features of the economy of Taiwan. Exports are a major contributor to economic growth and employment. Monetary policy and/or fiscal policy actions cause inflation. Price stability is vulnerable to the price fluctuation of Taiwan's trading partners. Fiscal policy is more effective in Taiwan than monetary policy. Taiwan has a business cycle of about 16 years. The Okun's law and the Phillip's curve can be applied.

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.

Urban areas experienced rapid changes in during the last century. With swiftly growing urban populations, the growth of urban areas has accelerated in the last couple of decades. Dealing with ¨Drapid¡¬ urbanization is an important concern in urban and spatial studies. The literature shows a wide variety of studies on the economic, social and cultural aspects of urban growth. Most recently, the concept of livability - quality of life - has been debated. This study attempts to measure of livability that is appropriate to the neighborhood scale. In this study, livability is measured with defined indicators: accessibility of public places (schools, health care centers, parks and gardens), availability of open spaces (green areas) and environmental quality (cleanliness of the city, rainwater management and safety). Old and new neighborhoods of Denizli-Turkey were selected as the study site. The research explores differences between old and new neighborhoods in developing cities, in case of livability based on selected indicators. 1029 surveys were conducted with residents of the study areas. People were asked about current conditions of their city and neighborhood, availability and quality of the public services and environmental quality related to study indicators. All results from the surveys were descriptively analyzed and spatially represented. Based on the results, there is no concentration neither in new or old neighborhood in terms of accessibility. New neighborhoods on the city edge have advantage of availability of green spaces and higher values of environmental quality.

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.

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.

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.

The legacy of master piano teacher Marvin Blickenstaff (b. 1935) is documented in this study through an analysis of his philosophy and pedagogical style and of his contributions to the field of piano pedagogy. Blickenstaff's extensive career includes teaching piano to all ages for over fifty years, giving presentations to teachers both nationally and internationally since the later 1960s, and publishing writings on teaching and materials for students. His major professional positions have included a professorship at the University of North Carolina at Chapel Hill for ten years (1969-78) and at Goshen College for twenty-one years (1978-99), and presidency of the Board of Trustees of the Frances Clark Center for Keyboard Pedagogy since 2000.
The primary resources for this study were Blickenstaff's publications and presentations, recordings of his piano lessons and classes, interviews, and surveys. The principal investigator conducted six interviews with Blickenstaff and interviewed twenty-two of his colleagues and students. To span the breadth of Blickenstaff's career, thirty-seven additional students and thirty-six teachers were surveyed. The interviews and surveys revealed how Blickenstaff's professional works impacted individuals within the field of piano pedagogy and established his philosophy and teaching style. Twenty-one piano lessons, a small-group lesson, and two classes were observed in 2009 at his home studio in Pennsylvania and at the New School for Music Study in New Jersey. These lessons are excerpted throughout this study to validate and demonstrate the tenets of Blickenstaff's philosophy and his pedagogical strategies. Blickenstaff's output as a presenter was analyzed through his presentation notes and through videos of his workshops and masterclasses. The major publications that Blickenstaff coauthored are the Handbook for Teachers published in conjunction with the Celebration Series, and Music Pathways, a method for beginning pianists. In addition, Blickenstaff's articles in the journal Keyboard Companion were consulted.
The eight chapters of this study document Blickenstaff's career, philosophy, and pedagogical style. In the introductory chapter, the purpose and justification of the study is established. The methodology and research procedures are presented in chapter two along with a summary of related studies. Chapter three contains a biography of Blickenstaff that chronicles his significant professional activities. Blickenstaff's philosophy of music education is outlined and validated in chapters four, five, and six. Chapter four presents Blickenstaff's viewpoint on the definition of music, the teacher, and the student. In chapter five, Blickenstaff's foundations for music study are explored through an analysis of the value of music study and the qualities of the student-teacher relationship. His philosophy on the learning process is detailed in chapter six, which includes an examination of the learning environment and how humans learn. In chapter seven, Blickenstaff's pedagogical style is codified through a summary of his lesson content, teaching techniques, and style of communication. The final chapter addresses the research questions posed in chapter one and synthesizes his philosophy, pedagogical style, and contributions to the field of piano pedagogy into his legacy. The ten appendices include lists of his publications, articles, recordings, and presentations, as well as transcripts of all interviews with Blickenstaff and reproductions of the questionnaires administered to piano teachers and his students.

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.

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.

Managing construction projects is a complex operation. Multiple activities are executed at the same time, and numerous variables impact building development. Therefore, construction professionals need access to worksite information to understand the current state of the project; this will allow them to make better analyses and decisions that may improve project performance. Thus, the more information that decision-makers can obtain from the job site, the better they will be able to identify problems and find solutions. Current software applications allow data visualization for project control and monitoring. However, multiple elements are not supported by these systems, which makes them a poor communication mechanism. Data is not collected nor analyzed efficiently, and a thorough study of current project conditions cannot be performed, which may lead to poor results. Consequently, a system capable of classifying, organizing, and storing data was implemented to test the usability of data visualization systems in the interpretation of ongoing project progress based on activity data. The test demonstrated that construction data visualization provided valuable information to construction professionals and that the application of this system enabled the exploration of various data relationships significant for project management.

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.

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.
