Information Content of Iron Butterfly Arbitrage Bounds
Informed traders trade options on underlying securities to lower transaction costs and increase financial leverage for price trend and variance strategies. Options markets play a significant role in price discovery by incorporating private information about future prices for an underlying security into option prices. I generate a new model-free volatility measure to calculate the "distance from arbitrage bounds" from minute-by-minute option series for the S&P 500 index and 30 individual underlying stocks. These iron butterfly arbitrage bounds (IBBs) use intraday call and put option prices from the Bloomberg database. Narrow and wide IBBs are expected to reveal the options market valuation of volatility by market participants. Data series is gathered by using successive one-minute intervals from the Bloomberg database. The data comprise the most recent bid and ask option prices and volumes. I collect S&P 500 index values and index options and use 30 underlying stock prices and option prices for the contracts that have the largest option trading volume during the sampling interval. These bid and ask prices reflect the information generated by intraday price pressures implied by S&P 500 index options or stock options. Consistent with the option micro-structure literature, I find that the IBB measure for actively traded stock options attains its highest level immediately after the open of the market, declines steadily throughout the first trading hour and remains relatively stable until market close. However, index IBBs behave differently. S&P 500 index option IBB attains its lowest level during the first hour of the trading day, then increases and remains relatively stable until market close. I present new evidence regarding the dynamic relation between stock returns and innovations in expected volatility by using the minute-by-minute change in implied volatility (IV) as a proxy. Unlike the relationship between individual stock returns and their respective changes in implied ...
A History of Overcoming: Nietzsche on the Moral Antecedents and Successors of Modern Liberalism
This work aims to understand human moral psychology under modern liberalism by analyzing the mature work of philosopher Friedrich Nietzsche. I seek to understand and evaluate Nietzsche's claim that liberalism, rather than being an overturning of slave morality, is an extension of the slave morality present in both Judaism and Christianity. To ground Nietzsche's critique of liberalism theoretically, I begin by analyzing his "master" and "slave" concepts. With these concepts clarified, I then apply them to Nietzsche's history by following his path from Judaism to liberalism and beyond--to his "last man" and Übermensch. I find that Nietzsche views history as a series of overcomings wherein a given mode of power maintenance runs counter to the means by which power was initially attained. Liberalism, as the precursor and herald of the "last man," threatens the end of overcoming and therefore compromises the future of human valuation and meaning.

Improving the Long-term Performance of PVC Compositions
PVC are extensively applied in many fields, such as cables, pipes, vehicles, shoes, toys and infusion bags. Generally, plasticizers are blended with PVC to improve the ability of process in industrial production; however, the toxic plasticizers will gradually migrate to the surface of products and such a leakage results in brittleness of plasticized PVC and environmental pollution. In other words, humans are frequently exposed to the potential risks. According to previous researches, cross-linked PVC was proved that it was able to hinder the migration of plasticizer. Thus, in this research, we selected some commercially used cross-linking agents and employed six different tests based on mechanical, tribological and microscopy analysis in order to seek the best solution against plasticizer migration. Thus, we expected to develop a cross-linked flexible PVC which performed improved long-term performance and extended lifetime.
Evolving Curricular Models in Culinary Arts: An Instrumental Case Study of a Technical Field
The purpose of this research study was to examine how chefs and other individuals in the food industry understood the field of culinary arts. This study used an instrumental case study with purposeful sampling of multiple cases. Through a series of open-ended interviews using snowball-sampling strategy that concluded with 45 participants sharing their experiences in culinary education and employment, several themes emerged across all of the interviews: (1) Disempowerment of those who have been successful in the culinary arts; (2) Conflict in the field; and, (3) Needs of employers not being met. Following the analysis of the data, two research questions were inductively formed: (1) How do the participants' understandings vary based upon the three models (apprenticeship, associate degree, and baccalaureate degree) of culinary education? (2) How do these themes vary depending upon the three models of culinary education? What resulted was thick description of the impact of the three models of formal chef education has had on the field of culinary arts, followed by the potential in the development of the baccalaureate degree model as it represented an opportunity for field redefinition in culinary arts. This study produced a set of data revealing that current culinary education has become one that has bred disempowerment, continued conflict in the field of culinary arts, and left needs unfullfilled related to technical skills required for successful employment. The shift from the time-consuming and expensive model of apprenticeship to the development of the associate degree has necessitated a reconsideration of culinary education. What has been offered in this research is the potential for a transformation facilitated within a baccalaureate degree that could intertwine both technical skills and academic knowledge.
The Relation of Perceived Motivational Climate, Mindset, and Achievement Goal Orientation to Grit in Male High School Soccer Players
Grit is defined as "perseverance and passion for long-term goals." Although studied in relation to various outcomes, such as retention and academic performance, few studies have examined variables that may contribute to grit's development. Further, few studies have examined this construct in relation to sport performance or within athletic environments, despite its clear connection to sport-related constructs like mental toughness and resilience. Thus, based in achievement motivation theory, this study examined the relations of the perceived motivational climate as defined by athletes' perceptions of the coaches' behaviors (task vs. ego), athletes' perceptions of their achievement goal orientation (task vs. ego), athletes' perceptions of their implicit theory (i.e., fundamental beliefs regarding whether or not ability can change; growth vs. fixed), and athletes' perception of their level of grit. Male varsity soccer players (N = 81; Mage = 15.80 ± .81) from a large metropolitan area in the south central U.S. completed questionnaires measuring these achievement motivation constructs. The full regression model was significant, accounting for 18% of the grit variance, F(6, 74) = 2.77, p = .017. Within the full model, having a growth mindset (β = .25, p = .035) and endorsing a task goal orientation (β = .36, p = .004) predicted higher levels of grit for the athletes. Neither the coach-created motivational climate, nor the athletes' ego orientation or fixed mindset, were significantly predicted their grit scores. Consistent with Dweck and Duckworth, components of achievement motivation theory, particularly related to a task or growth perspective, may play an important role in athletes' developing a perspective that allows them to work effectively and diligently toward long-term goals.
Analyzing Tuberculosis Vulnerabilities and Variables in Tarrant County
Over 9 million new cases of tuberculosis (TB) were reported worldwide in 2013. While the TB rate is much lower in the US, its uneven distribution and associated explanatory variables require interrogation in order to determine effective strategies for intervention and control. However, paucity of case data at fine geographic scales precludes such research. This research, using zip code level data from 837 confirmed TB cases in Tarrant County obtained from Texas Department of State Health Services, explores and attempts to explain the spatial patterns of TB and related risk markers within a framework of place vulnerability. Readily available census data is then used to characterize the spatial variations in TB risk. The resulting model will enable estimations of the geographic differences in TB case variables using this readily available census data instead of time-consuming and expensive individual data collection.
Sliding Friction and Wear Behavior of High Entropy Alloys at Room and Elevated Temperatures
Structure-tribological property relations have been studied for five high entropy alloys (HEAs). Microhardness, room and elevated (100°C and 300°C) temperature sliding friction coefficients and wear rates were determined for five HEAs: Co0.5 Cr Cu0.5 Fe Ni1.5 Al Ti0.4; Co Cr Fe Ni Al0.25 Ti0.75; Ti V Nb Cr Al; Al0.3CoCrFeNi; and Al0.3CuCrFeNi2. Wear surfaces were characterized with scanning electron microscopy and micro-Raman spectroscopy to determine the wear mechanisms and tribochemical phases, respectively. It was determined that the two HEAs Co0.5 Cr Cu0.5 Fe Ni1.5 Al Ti0.4 and Ti V Nb Cr Al exhibit an excellent balance of high hardness, low friction coefficients and wear rates compared to 440C stainless steel, a currently used bearing steel. This was attributed to their more ductile body centered cubic (BCC) solid solution phase along with the formation of tribochemical Cr oxide and Nb oxide phases, respectively, in the wear surfaces. This study provides guidelines for fabricating novel, low-friction, and wear-resistant HEAs for potential use at room and elevated temperatures, which will help reduce energy and material losses in friction and wear applications.
The Castle/Nikki Heat Phenomenon: A Detailed Examination of Female Representation in Entertainment Media
As entertainment reflects a culture's ideology, it is important for researchers to study its messages and subsequently its potential meanings. Entertainment has the power to inform and persuade, creating models for behavior with which the public interacts. The entertainment texts for the purpose of this study are the Castle television series and the Nikki Heat novels. Together, they create a unique multi-layer fictional world. By using postmodern, feminist, communication, and entertainment theories, the results of this study provide a tightly focused lens which views a narrow aspect of entertainment media. Each text was thoroughly examined using textual analysis, Feminist Poststructuralist Discourse Analysis, and conversation analysis. Contrary to expectations, the results indicated that the Castle and Nikki Heat texts support hegemonic ideology, particularly through the use of exaggerated stereotypes, strict gender roles, imagery, and narrative choices that help perpetuate rape culture. The discussion outlines how these results can be interpreted through the dominant messages presented in the texts. This research is intended to serve as a foundation for future research regarding entertainment media.
Friends of the State Courts: Organized Interests and State Courts of Last Resort
Why do interest groups participate in state courts of last resort by filing amicus curiae briefs? Are they influential when they do? This dissertation examines these questions using an original survey of organized interests that routinely participate in state supreme courts, as well as data on all amicus curiae briefs and majority opinions in over 14,000 cases decided in all fifty-two state supreme courts for a four year period. I argue that interest groups turn to state judiciaries to achieve the dual goals of influencing policy and organizational maintenance, as amicus briefs can help organized interests achieve both outcomes. Furthermore, I contend that amicus briefs are influential in shaping judicial policy-making through the provision of legally persuasive arguments. The results suggest that interest groups do file amicus briefs to both lobby for their preferred policies and to support their organization's long-term viability. Additionally, the results indicate that organized interests also participate in counteractive lobbying in state courts of last resort by filing amicus briefs to ensure their side is represented and to dull the effect of oppositional amici. The findings also demonstrate support for the influence of amicus briefs on judicial policy-making on state high courts, as amicus briefs can influence the ideological direction of the court's majority opinions. Overall, this research extends our understanding of interest group lobbing in the judiciary and in state policy venues, and provides insight into judicial politics and policy-making on state courts of last resort.
Examining the Impact of the Community of Inquiry and Student Learning Process on Participants' Academic Achievement
This dissertation presents an empirical investigation of learning from online courses. The current dissertation examined student participation, using Arbaugh et al.'s Community of Inquiry (CoI) survey instrument and Biggs et al.'s revised version of the Study Process Questionnaire (R-SPQ-2F) to determine CoI influences on learning from the students' perspective. This study is in response to Rourke and Kanuka's call to provide further empirical evidence about CoI conceptual framework connections to deep and meaningful learning. The purpose of this study was to examine the impact of the elements of CoI, cognitive, social, and teaching presences and students' learning approaches to students' perceived learning. Students enrolled in traditional, online, and, blended courses during the 2016 spring semester at a southwestern university participated in a web-based survey. Structural equation modeling was used to test the indirect effects between the elements of CoI, learning approaches, and perceived learning. Student's deep approach to learning was found to have an indirect effect between cognitive presence and perceived learning. However, this study's findings, when the CoI framework was viewed in its entirety, failed to provide evidence to simulate deep and meaningful learning.
Privacy Preserving EEG-based Authentication Using Perceptual Hashing
The use of electroencephalogram (EEG), an electrophysiological monitoring method for recording the brain activity, for authentication has attracted the interest of researchers for over a decade. In addition to exhibiting qualities of biometric-based authentication, they are revocable, impossible to mimic, and resistant to coercion attacks. However, EEG signals carry a wealth of information about an individual and can reveal private information about the user. This brings significant privacy issues to EEG-based authentication systems as they have access to raw EEG signals. This thesis proposes a privacy-preserving EEG-based authentication system that preserves the privacy of the user by not revealing the raw EEG signals while allowing the system to authenticate the user accurately. In that, perceptual hashing is utilized and instead of raw EEG signals, their perceptually hashed values are used in the authentication process. In addition to describing the authentication process, algorithms to compute the perceptual hash are developed based on two feature extraction techniques. Experimental results show that an authentication system using perceptual hashing can achieve performance comparable to a system that has access to raw EEG signals if enough EEG channels are used in the process. This thesis also presents a security analysis to show that perceptual hashing can prevent information leakage.
Influence of Underlying Random Walk Types in Population Models on Resulting Social Network Types and Epidemiological Dynamics
Epidemiologists rely on human interaction networks for determining states and dynamics of disease propagations in populations. However, such networks are empirical snapshots of the past. It will greatly benefit if human interaction networks are statistically predicted and dynamically created while an epidemic is in progress. We develop an application framework for the generation of human interaction networks and running epidemiological processes utilizing research on human mobility patterns and agent-based modeling. The interaction networks are dynamically constructed by incorporating different types of Random Walks and human rules of engagements. We explore the characteristics of the created network and compare them with the known theoretical and empirical graphs. The dependencies of epidemic dynamics and their outcomes on patterns and parameters of human motion and motives are encountered and presented through this research. This work specifically describes how the types and parameters of random walks define properties of generated graphs. We show that some configurations of the system of agents in random walk can produce network topologies with properties similar to small-world networks. Our goal is to find sets of mobility patterns that lead to empirical-like networks. The possibility of phase transitions in the graphs due to changes in the parameterization of agent walks is the focus of this research as this knowledge can lead to the possibility of disruptions to disease diffusions in populations. This research shall facilitate work of public health researchers to predict the magnitude of an epidemic and estimate resources required for mitigation.
Design and Manufacture of Molding Compounds for High Reliability Microelectronics in Extreme Conditions
The widespread use of electronics in more avenues of consumer use is increasing. Applications range from medical instrumentation that directly can affect someone's life, down hole sensors for oil and gas, aerospace, aeronautics, and automotive electronics. The increased power density and harsh environment makes the reliability of the packaging a vital part of the reliability of the device. The increased importance of analog devices in these applications, their high voltage and high temperature resilience is resulting in challenges that have not been dealt with before. In particular packaging where insulative properties are vital use polymer resins modified by ceramic fillers. The distinct dielectric properties of the resin and the filler result in charge storage and release of the polarization currents in the composite that have had unpredictable consequences on reliability. The objective of this effort is therefore to investigate a technique that can be used to measure the polarization in filled polymer resins and evaluate reliable molding compounds. A valuable approach to measure polarization in polymers where charge release is tied to the glass transition in the polymer is referred to as thermally stimulated depolarization current (TSDC) technique. In this dissertation a new TSDC measurement system was designed and fabricated. The instrument is an assembly of several components that are automated via a LabVIEW program that gives the user flexibility to test different dielectric compounds at high temperatures and high voltage. The temperature control is enabled through the use of dry air convection heating at a very slow rate enabling controlled heating and cooling. Charge trapping and de-trapping processes were investigated in order to obtain information on insulating polymeric composites and how to optimize it. A number of material properties were investigated. First, polarization due to charges on the filer were investigated using composites containing charged and uncharged particles using ...

Clinical Symptoms and Signs Related to Voice Disorders among Collegiate-Level Singers: A Retrospective Study
The objectives of this research were to (1) characterize the demographics and vocal health history of collegiate-level singers, particularly those with a voice disorder and (2) describe and compare self-reported symptoms of singers across diagnostic categories of vocal fold disorders. Clinical reports of 56 collegiate-level singers (15 male and 41 female) who visited the Voice Diagnostic Clinic at the University of North Texas for voice evaluations between 2010 and 2015 were reviewed. Information was extracted from clinical records including demographic data, vocal health history, self-reported voice-related symptoms, and voice diagnosis confirmed by strobolaryngoscopic examinations and phonatory function testing. Diagnoses of voice disorders were grouped under three categories: normal (i.e., no perceptible pathology), benign lesions and irritation/inflammation. Seven singers were diagnosed as normal, 27 (51.8%) with benign lesions, and 22 (39.3%) with irritation/inflammation. All singers diagnosed as normal were females. Female singers have twice as many benign lesions as irritation/inflammation whereas males presented the opposite pattern. Nodules, polyps, cysts and irritation/inflammation were the most common voice disorders. Singers with allergies and a past history of voice problems demonstrated a higher incidence of voice disorders. The top five self-reported vocal symptoms were worse voice in the morning (50%), pain in throat (46.4%), voice worse with prolonged use (44.6%), vocal fatigue (42.9%), and breathiness (41.1%). Self-reported symptoms are not a reliable screening tool to determine presence or absence of vocal pathology. Voice teachers must be familiar with the singing and speaking voice of each student, so as to perceive early onset of vocal attrition symptoms and encourage the student in seeking medical attention.
The 50,000 Watt Blowtorch of the Great Southwest: The History of WBAP
This paper looks at the history of WBAP while examining how programming has changed from 1922-2014 and how WBAPs audience helped shape programming at the station. This paper reveals four formatting changes throughout the stations history and provides in-depth statistical analysis of how WBAPs audience changed during the stations 90 plus years of existence.
Low-Energy Electron Irradiation of Preheated and Gas-Exposed Single-Wall Carbon Nanotubes
We investigate the conditions under which electron irradiation of single-walled carbon nanotube (SWCNT) bundles with 2 keV electrons produces an increase in the Raman D peak. We find that an increase in the D peak does not occur when SWCNTs are preheated in situ at 600 C for 1 h in ultrahigh vacuum (UHV) before irradiation is performed. Exposing SWCNTs to air or other gases after preheating in UHV and before irradiation results in an increase in the D peak. Small diameter SWCNTs that are not preheated or preheated and exposed to air show a significant increase in the D and G bands after irradiation. X-ray photoelectron spectroscopy shows no chemical shifts in the C1s peak of SWCNTs that have been irradiated versus SWCNTs that have not been irradiated, suggesting that the increase in the D peak is not due to chemisorption of adsorbates on the nanotubes.
Contributions to Descriptive Set Theory
Assume AD+V=L(R). In the first chapter, let W^1_1 denote the club measure on \omega_1. We analyze the embedding j_{W^1_1}\restr HOD from the point of view of inner model theory. We use our analysis to answer a question of Jackson-Ketchersid about codes for ordinals less than \omega_\omega. In the second chapter, we provide an indiscernibles analysis for models of the form L[T_n,x]. We use our analysis to provide new proofs of the strong partition property on \delta^1_{2n+1}
Family and Cultural Influences on Latino Emerging Adults' Career Development
There is an extensive amount of research on career development, but most of the constructs studied have focused on content-oriented variables rather than process-oriented variables. While some of the studies have examined samples from ethnic minority populations, the majority of studies use ethnic minority populations as comparison groups, studying between-group differences as opposed to within-group differences. The literature is especially deficient in the are of Latino career development. The current study will examine how family and culture influence the career development of Latino emerging adults. This study will explore the influence of socioeconomic status and acculturation on the career salience and career maturity of Latino emerging adults. The quality of the parent-emerging adult relationship will also be explored for its influence on career development outcomes in this population. One hundred fifty Latino undergraduate students ages 18-24 will be recruited for participation in this study. The participants will complete questionnaires regarding demographic information, acculturation, the quality of the parent-emerging adult relationship, career salience, and career maturity.
Rankin-Cohen Brackets for Hermitian Jacobi Forms and Hermitian Modular Forms
In this thesis, we define differential operators for Hermitian Jacobi forms and Hermitian modular forms over the Gaussian number field Q(i). In particular, we construct Rankin-Cohen brackets for such spaces of Hermitian Jacobi forms and Hermitian modular forms. As an application, we extend Rankin's method to the case of Hermitian Jacobi forms. Finally we compute Fourier series coefficients of Hermitian modular forms, which allow us to give an example of the first Rankin-Cohen bracket of two Hermitian modular forms. In the appendix, we provide tables of Fourier series coefficients of Hermitian modular forms and also the computer source code that we used to compute such Fourier coefficients.
The Impact of Psychotherapeutic Reiki on Anxiety and Mindfulness: A Single-Case Design
Reiki healing is one of several complementary and integrative therapies becoming increasingly prevalent in mental health counseling. It has been identified in the medical field for its usefulness in treating anxiety, depression, distress, and pain but has rarely been studied for its counseling impact on client wellness. I conducted single-case research to explore psychotherapeutic Reiki's (PR's) influence on adult clients' anxiety symptoms and perceived sense of mindfulness and provided analysis of data collected from two assessments administered weekly: the Adult Manifest Anxiety Scale-Adult and the Mindful Attention Awareness Scale. Three of the four participants demonstrated significant improvement in both anxiety and mindfulness over the course of the PR intervention. The study revealed potential therapeutic benefits for integrating PR with conventional talk therapy. Included in discussion of study results are clinical implications and importance, suggestions for future research, and limitations.
Cognitive Engagement in Later Life: Descriptive and Explanatory Findings
Findings on the relationship between engagement in lifestyle and cognitive functioning are not consistent; some authors report that engagement in lifestyle predicts an individual's cognitive functioning; while other report that an individual's cognitive functioning predicts the type and level of engagement an individual participates in. The current study will use longitudinal data (N = 235) to investigate the bidirectional relationship between engagement (engaged lifestyle activities) and cognition (crystallized & fluid intelligence). Despite inconsistent findings it is proposed that cognitive functioning may be better understood when examining how stimulation of activity, need for cognition, and openness to experience affect engagement in an active lifestyle. As such the current study will investigate if stimulation of activity, need for cognition, and openness to experience moderate the relationship between engaged lifestyles and cognitive functioning. The results, limitations and implications are discussed.
Modeling of Hexagonal Boron Nitride Filled Bismalemide Polymer Composites for Thermal and Electrical Properties for Electronic Packaging
Due to the multi-tasking and miniaturization of electronic devices, faster heat transfer is required from the device to avoid the thermal failure. Die-attached polymer adhesives are used to bond the chips in electronic packaging. These adhesives have to hold strong mechanical, thermal, dielectric, and moisture resistant properties. As polymers are insulators, heat conductive particles are inserted in it to enhance the thermal flow with an attention that there would be no electrical conductivity as well as no reduction in dielectric strength. This thesis focuses on the characterization of polymer nanocomposites for thermal and electrical properties with experimental and computational tools. Platelet geometry of hexagonal boron nitride offers highly anisotropic properties. Therefore, their alignment and degree of orientation offers tunable properties in polymer nanocomposites for thermal, electrical, and mechanical properties. This thesis intends to model the anisotropic behavior of thermal and dielectric properties using finite element and molecular dynamics simulations as well as experimental validation.
Real Time Assessment of a Video Game Player's State of Mind Using Off-the-Shelf Electroencephalography
The focus of this research is on the development of a real time application that uses a low cost EEG headset to measure a player's state of mind while they play a video game. Using data collected using the Emotiv EPOC headset, various EEG processing techniques are tested to find ways of measuring a person's engagement and arousal levels. The ability to measure a person's engagement and arousal levels provide an opportunity to develop a model that monitor a person's flow while playing video games. Identifying when certain events occur, like when the player dies, will make it easier to identify when a player has left a state of flow. The real time application Brainwave captures data from the wireless Emotiv EPOC headset. Brainwave converts the raw EEG data into more meaningful brainwave band frequencies. Utilizing the brainwave frequencies the program trains multiple machine learning algorithms with data designed to identify when the player dies. Brainwave runs while the player plays through a video gaming monitoring their engagement and arousal levels for changes that cause the player to leave a state of flow. Brainwave reports to researchers and developers when the player dies along with the identification of the players exit of the state of flow.
Parcel-Based Change Detection Using Multi-Temporal LiDAR Data in the City of Surrey, British Columbia, Canada
Change detection is amongst the most effective critical examination methods used in remote sensing technology. In this research, new methods are proposed for building and vegetation change detection using only LiDAR data without using any other remotely sensed data. Two LiDAR datasets from 2009 and 2013 will be used in this research. These datasets are provided by the City of Surrey. A Parcel map which shows parcels in the study area will be also used in this research because the objective of this research is detecting changes based on parcels. Different methods are applied to detect changes in buildings and vegetation respectively. Three attributes of object –slope, building volume, and building height are derived and used in this study. Changes in buildings are not only detected but also categorized based on their attributes. In addition, vegetation change detection is performed based on parcels. The output shows parcels with a change of vegetation. Accuracy assessment is done by using measures of completeness, correctness, and quality of extracted regions. Accuracy assessments suggest that building change detection is performed with better results.
The Effects of Student-Perceived Instructor Demotivating Behaviors on Doctoral Students' Information Seeking Behaviors
In their studies on student motivation in th4e 1990s, Gorham & Christophel and Christophel & Gorham found that students perceived their own demotivation to be caused by instructor behaviors. While there are studies that explore the topic of student demotivation and other studies that illustrate the great influence instructors have on student information seeking behaviors, research focusing on the connection between these two concepts is almost nonexistent. Using Gorham & Christophel's concept of instructor-owned student demotivation, this mixed-methods study sought to identify which instructor behaviors doctoral computer science and information science students found demotivating and to what extent their perceptions of these demotivating instructor behaviors influenced their information seeking behaviors in a face-to-face classroom. Demographic and student-perceived demotivating instructor behavior surveys along with semi-structured interviews and follow-up questions were used to collect data. The surveys will be analyzed using descriptive statistics in Excel, and the semi-structured interviews and follow up questions were analyzed using content analysis and Colaizzi's method of phenomenological enquiry in NVivo. The findings showed that instructor demotivating behaviors not only influence student information seeking behaviors in the classroom, but they also can lead to lasting effects on the student. In addition, the participants have expectations of instructor behaviors, which come from their own experiences. These expectations also influence the level of demotivation they feel in a face-to-face classroom.
Unclean Slates: Stories
Unclean Slates: Stories is a collection of seven short stories that comments on the nature of family ties, and how such ties help form a sense of identity. Each story focuses on a separate protagonist, all of whom strive for a new beginning or an escape from some aspect of their current lives. The short story cycle of this collection is held together not by place or characters, but ultimately by the theme of wishing for a new beginning: they share a desire to fix some dissatisfying element of their lives. Mostly from the point of view of blue-collar characters leading mundane middle-class lives, these stories provide commentary on what it means to run from the conditions that make up one's sense of identity. Most of the revelations formed throughout these stories lead to a sense of acceptance of these conditions, and an understanding that family and history make up part of human consciousness. While the specific locations presented in these stories are not necessarily the same, each story seeks to focus on a location that proves to be fundamental to the makeup of the protagonist. The cities and geographic locations themselves are not as important as the specifics: the schools, diners, lakes, and so forth where these characters find themselves contemplating their disillusionment about where their lives have brought them. Facing everything from postpartum depression to simply missing out on a career opportunity, these characters all experience a sense of loss that brings them together in a way that is recognizable to the reader as the collection progresses.
Legal Compliance in Guardianship Cases An Exploratory Study: Investigating Denton County Probate Court Visitors' Program Success with Legal Compliance in Guardianship Cases in 2013
Dabner, Carol P. Legal Compliance in Guardianship Cases. An Exploratory Study: Investigating Denton County Probate Court Visitors' Program Success with Legal Compliance in Guardianship Cases. Doctor of Philosophy (Applied Gerontology), December 2016, 140 pp., 18 tables, references, 20 titles. Aim: To evaluate the effectiveness of the legal compliance of the Denton County Probate Court Visitor's program in the year 2013. Rationale: Guardianship case management success is based on the presence of legal compliance of both guardians and the Court. When a guardian is legally compliant, a ward is receiving the statutorily minimum standards of care. Legal compliance equates (evidence of) the Ward receiving legally sufficient care. Research has not been vast; it has been consistent as to necessity of guardianship training, monitoring, and narrow focus of research. Evidence based research will assist in defining and developing appropriate court monitoring programs, which can add to the quality of care for elderly and disabled adults. Methods: 1,300 guardianship cases in the probate court. Of these cases, 910 had annual reports of the person filed, which 304 were reviewed using the Legal Compliance Audit. Eight (8) factors of compliance were reviewed with three (3) being Court actions and five (5) being guardian actions. Results: Exploratory study provides evidence based research of the necessary changes to develop the Denton County Probate Court Visitor's program. The guardians are more legal compliant than the Court.
Dissimilar Joining of Al (AA2139) – Mg (WE43) Alloys Using Friction Stir Welding
This research demonstrates the use of friction stir welding (FSW) to join dissimilar (Al-Mg) metal alloys. The main challenges in joining different, dissimilar metal alloys is the formation of brittle intermetallic compounds (IMCs) in the stir zone affecting mechanical properties of joint significantly. In this present study, FSW joining process is used to join aluminum alloy AA2139 and magnesium alloy WE43. The 9.5 mm thick plates of AA2139 and WE43 were friction stir butt welded. Different processing parameters were used to optimize processing parameters. Also, various weldings showed a crack at interface due to formation of IMCs caused by liquation during FSW. A good strength sound weld was obtained using processing parameter of 1200 rev/min rotational speed; 76.2 mm/min traverse speed; 1.5 degree tilt and 0.13 mm offsets towards aluminum. The crack faded away as the tool was offset towards advancing side aluminum. Mostly, the research was focused on developing high strength joint through microstructural control to reduce IMCs thickness in Al-Mg dissimilar weld joint with optimized processing parameter and appropriate tool offset.
Modeling Cognitive Authority Relationships
Information-seeking behavior is a mixture of activities and attitudes, oftentimes motivated by an individual's need to make a decision. One underlying element of this mixture is cognitive authority - which sources (e.g., individuals, institutions, texts, etc.) can be trusted to fulfil the information needs? In order to gain insight into the dynamics of cognitive authority selection behavior which is an information seeking behavior, this study explored primary source text data (316 text records) that reflected selection in the mundaneness of life (advice column submissions and responses). Linguistic analysis was performed on the data using the Linguistic Inquiry Word Count (LIWC2015) software package. Pearson correlation and 1-sample T tests revealed the same 45 statistically significant relationships (SSRs) in the word usage behavior of all subgroups. As a result of the study, the gap in research formed from the lack of quantitative models of cognitive authority relationships was addressed via the development of the Wordprint Classification System which was used to generate a cognitive authority relationship model in the form of a cognitive authority intra-segment wordprint. The findings and implications of this study may provide a contribution to the body of work in the area of information literacy and information seeker behavior by revealing factors that information scientists can address to help meet information seekers' needs. Additionally, the Wordprint Classification System may be used in such disciplines as psychology, marketing, and forensic linguistics to create to create models of various relationships or individuals through the use of written or spoken word usage patterns.

State Library Administrative Agencies Survey: Fiscal Year 2014
The State Library Administrative Agencies Survey: Fiscal Year 2014 report provides a view of the condition of state library administrative agencies in the 50 states and the District of Columbia for Fiscal Year 2014. The data includes state library agency identification, governance, public service hours, service outlets, collections, library service transactions, library development transactions, services to other libraries in the state, allied operations, staff, income, expenditures, and electronic services and information. State libraries administer federal funds through the IMLS Grants to States program and play a crucial role in helping libraries within their state meet the demand for content and services by establishing statewide plans for library services, investing in technology and content, and providing support for local programming. While the state libraries continued to offer a wide array of library services in 2014, the study results showed a multi-year pattern of decreases in revenues, expenditures, and staffing that coincided with the Great Recession of 2007-2009. The revenue from federal, state, and other sources to state library agencies totaled $1.1 billion in FY 2014, a 17 percent decrease in revenue from FY 2004.The report is useful to Chief Officers of State Library Agencies (COSLA), policymakers in the executive and legislative branches of federal and state governments, government and library administrators at the federal, state, and local levels, the American Library Association and its members or customers, library and public policy researchers, the public, journalists, and others.
