Compared To What? The Effectiveness Of Synthetic Control Methods For Causal Inference In Educational Assessment, Clay Stephen Johnson

Graduate Theses and Dissertations

Synthetic control methods are an innovative matching technique first introduced within the economics and political science literature that have begun to find application in educational research as well. Synthetic controls create an aggregate-level, time-series comparison for a single treated unit of interest for causal inference with observational data. However, the strict statistical assumptions associated with matching methods for causal inference raise concerns for unobserved bias related to some data models and availability. The small but increasing set of existing synthetic controls studies with student achievement measures as the outcome of interest suggest that research is warranted into the effectiveness of …

An Open Source, Line Rate Datagram Protocol Facilitating Message Resiliency Over An Imperfect Channel, Christina Marie Smith

Graduate Theses and Dissertations

Remote Direct Memory Access (RDMA) is the transfer of data into buffers between two compute nodes that does not require the involvement of a CPU or Operating System (OS). The idea is borrowed from Direct Memory Access (DMA) which allows memory within a compute node to be transferred without transiting through the CPU. RDMA is termed a zero-copy protocol as it eliminates the need to copy data between buffers within the protocol stack. Because of this and other features, RDMA promotes reliable, high throughput and low latency transfer for packet-switched networking. While the benefits of RMDA are well known and …

Identifying Emerging Researchers Using Social Network Analysis, Syed Masum Billah

Graduate Theses and Dissertations

Finding rising stars in academia early in their careers has many implications when hiring new faculty, applying for promotion, and/or requesting grants. Typically, the impact and productivity of a researcher are assessed by a popular measurement called the h-index that grows linearly with the academic age of a researcher. Therefore, h-indices of researchers in the early stages of their careers are almost uniformly low, making it difficult to identify those who will, in future, emerge as influential leaders in their field. To overcome this problem, we make use of Social network analysis to identify young researchers most likely to become …

A Geomechanical Study Of The Mississippian Boone Formation, Karen Nicole Mason Buckland

Graduate Theses and Dissertations

The Boone Formation in northwest Arkansas is a chert-limestone sequence analogous to the subsurface Mississippi Lime reservoir in parts of Oklahoma and Kansas. It has low permeability and produces via horizontal drilling and hydraulic fracturing. The response to stimulation by fracturing is dependent on the quantity of chert in the area. Chert nodules and laterally extensive chert layers in the sequence are variable. Locally, cm- to dm-scale chert bedding is continuous and comprises up to 50% of the outcrop. Elsewhere, the chert is nodular and intermittent.

Samples collected from representative outcrops spanning the thickness and aerial extent of the formation …

On The Permanence Of Heideggerian Authenticity, Seth Daves

Graduate Theses and Dissertations

In this essay I pose the following question: is Heideggerian authenticity permanent? To investigate this question I begin with a thorough analysis of what Heidegger means by authenticity. Afterwards I look into the leading figures within the field, seeking guidance in answering the question of the permanence of Heideggerian authenticity. Ultimately I conclude that an amended version of John Haugeland's analysis of resoluteness gives rise to the affirmative response to my question. I conclude by investigating potential problems concluding that Heideggerian authenticity is permanent.

Structure-Function Relationship Of The Ligand-Binding Domain Of The Fibroblast Growth Factor Receptor, Ryan Thurman

Graduate Theses and Dissertations

The interactions between FGF and fibroblast growth factor receptors are responsible for the regulation of key cellular processes. FGF is important in both germ cell and embryonic developments. FGF continues to play important roles during adulthood by regulating embryogenesis, cell differentiation, and wound healing (1-7). The regulations of these cellular events are initiated through FGF binding to the fibroblast growth factor receptors. The complex formed by FGF and the receptor involves a key interaction with heparin. Through interactions with heparin, the FGF, FGFR and Heparin form a 2:2:2 complex (8). This complex formation results in autophosphorylation in the tyrosine kinase …

Teachers' Perceptions Toward Implementing English As A Foreign Language At Kindergarten: What Can We Learn From The Case Of Kuwaiti Kindergarten Teachers?, Kawthar M. Habeeb

Graduate Theses and Dissertations

The teaching of English as a foreign language has a promising outlook in the nation of Kuwait. Recent policy reflects language development theories that see early childhood as an especially good period for the learning of a foreign language. Thus, English is now taught at 30 public kindergartens in Kuwait. However, the program apparently was implemented quickly, with little consideration for how teachers and other stakeholders would respond to it. This paper explores that program in the context of the perceptions and views of teachers affected by it.

A review of the existing curriculum points towards deficiencies, and investigation of …

The Meaning Of Play For Adults From A Reversal Theory Perspective, Linda Lane

Graduate Theses and Dissertations

Play is important to adults' mental creativity and happiness (Marano, 1999), and stress reduction (Apter, 2009a; Baptiste, 1995). Yet play may be considered as trivial behavior that is not appropriate for the adult population. The purpose of the study was to examine how adults describe the concept of play and to determine whether this description reflects their dominant metamotivational state. According to reversal theory, these states are the frames of mind that characterize an individual's motivation at any given point in time (Apter, 1982). An individual tends to be in a more playful (paratelic) state or serious-minded (telic) state depending …

The Impact Of Selected Academic And Demographic Variables On Mathematics College Readiness Predicted By Act, Marcia Sue Smith

Graduate Theses and Dissertations

A multiple regression was used to analyze archival data to determine the impact the combined Arkansas Comprehensive Testing, Assessment and Accountability Program (ACTAAP) mathematics end-of-course (EOC) score, high school GPA, and highest mathematics class completed had on the ACT mathematics exam. In addition, a hierarchical multiple regression model was used to determine how English language learner (ELL) status and socio-economic status (SES) impacted students' ACT performance …

Turpentine Creek: Arkansas' Refuge, Jacob Paul Bain

Graduate Theses and Dissertations

The goal of this Master's thesis film project was twofold. First, I wanted to explore the problem, huge but relatively unknown, of the ownership of exotic pets in the United States of America. Second, in conjunction with that problem, I wanted to see how Turpentine Creek Wildlife Refuge (TCWR) approached it and what, as an organization, they do to help resolve this problem locally and nationally. In turn, the film also provides an in-depth look at a very unique refuge in the state of Arkansas. Using my own equipment, I shot and edited a short-form documentary about TCWR. The film …

Electrical Design Considerations And Packaging Of Power Electronic Modules, Shijie Wang

Graduate Theses and Dissertations

A modern power electronic module can save significant energy usage in the power electronic systems by improving their switching efficiencies. One way to improve the efficiency of the power electronic module is to reduce its parasitic circuit elements. The purpose of this thesis is to investigate the mitigation of parasitic circuit elements in power electronic modules. General methods of mitigating parasitic inductances were analyzed by the Q3D Extractor and verified by the time-domain reflectometry (TDR) measurements. In most cases, the TDR measurement results closely matched those predicted by the Q3D Extractor. These methods were applied to design and analyze a …

A Roadmap To Mindful Consumption Through Informative Labeling Practices: The Effects Of Sustainability Disclosure Formats On Consumer Product Evaluations, Yoon-Na Cho

Graduate Theses and Dissertations

Despite the interest of consumers in sustainable and environmentally friendly products, only a limited number of studies have focused on sustainability level disclosures for consumer packaged goods. The general overarching purpose of this dissertation is to extend the internal reference point and information processing literatures to better understand how consumers will process sustainability disclosures. Applying the theoretical lens of assimilation bias in conjunction with self-enhancement offers an important extension to prior work. Across two retail lab studies and four online experiments, I demonstrate that the perceived sustainability utility (i.e., the difference between a specific brand's level of sustainability and category-level …

Essays On The Economics Of Child Care And Child Custody, Jennifer Lee Hafer

Graduate Theses and Dissertations

In my first essay I use data from licensed child care centers in the state of Arkansas to examine the relationship between quality and price charged. To measure quality, I use Arkansas's Better Beginnings Quality Rating and Improvement System, a tier-structured voluntary certification program which can be viewed as a voluntary increase in regulations for licensed child care centers which allows them to send an observable signal of quality to consumers. Using an hedonic pricing estimation with controls for varying geographic markets, results indicate firms with Better Beginnings classification charge higher prices once the highest levels of certification are obtained. …

The Confounding Effects Of Ability, Item Difficulty, And Content Balance Within Multiple Dimensions On The Estimation Of Unidimensional Thetas, Ki Lynn Matlock

Graduate Theses and Dissertations

When test forms that have equal total test difficulty and number of items vary in difficulty and length within sub-content areas, an examinee's estimated score may vary across equivalent forms, depending on how well his or her true ability in each sub-content area aligns with the difficulty of items and number of items within these areas. Estimating ability using unidimensional methods for multidimensional data has been studied for decades, focusing primarily on subgroups of the population based on the estimated ability for a single set of data (Ackerman, 1987a, 1989; Ansley & Forsyth, 1985; Kroopnick, 2010; Reckase, Ackerman, & Spray, …

Do Changes In The Sg&A Ratio Provide Information About Changes In Future Earnings, Analyst Forecast Revisions, And Stock Returns?, Eugene Scott Johnson

Graduate Theses and Dissertations

In fundamental analysis, increases in the ratio of selling, general and administrative (SG&A) costs to sales (SG&A ratio) are viewed as negative signals about future firm performance. However, this interpretation focuses on the overall change in the SG&A ratio and ignores the underlying changes in the components of the ratio. For example, prior literature finds that the interpretation offered by fundamental analysis does not hold during periods of decreasing sales. I contend that a further partitioning of the full sample into subsamples representing all possible combinations of changes in the components of the SG&A ratio, and the ratio itself, will …

Decoding Literary Aids: A Study On Issues Of The Body, Masculinity, And Self Identity In U.S. Aids Literature From 1984-2011, Alexander Shimon Abrams

Graduate Theses and Dissertations

Rather than waiting decades to respond, novelists of nearly every literary genre began conceptualizing the AIDS epidemic shortly after the first documented case of the virus in the United States in 1981. Writers, feeling a sense of urgency, wasted little time constructing didactic texts that differ from much historical fiction in that they were written as the tragedy they are commenting on occurred. However, AIDS literature has changed as the disease has spread well beyond the gay communities of San Francisco and New York, causing people to reexamine their longstanding beliefs on masculinity, sexuality, and body politics.

My Master's thesis …

The Bipartisan Campaign Reform Act increased the individual donor limit to $2,000 per candidate per election and indexed the limit for inflation every two years. The primary research question guiding this study is how has the increase in the donor limit affected donor behavior. Answering this question should allow a determination to be made about how donors have responded to the increased donor limit. Understanding how donors responded to the doubled limit is important because it provides evidence on the intersection of wealth inequality and political influence. To answer the research question this study considers how the increased donor limit …

Your Media Speak So Loud I Can't Hear A Word You're Saying: Impact Of Media And Media Selection On Performance, Martin Hassell

Graduate Theses and Dissertations

With the proliferation of communication media and technologies available, it is important for teams to understand the influence of these media on the performance of their communications. Additionally, it is important for researchers to understand how teams choose and use media. Literature on communication media impacts and communication performance has been somewhat fragmented, and researchers have used different theories and paradigms to study this problem. Researchers still do not have a full understanding of how media influences communication, whether teams recognize and select appropriate media for their communication needs, and what makes some communication more effective, irrespective of the communication …

Understanding Collaborative Dynamics: A Critical Review And Inductive Investigation, Amydee Mackley Fawcett

Graduate Theses and Dissertations

Collaboration has been a topic of discussion for over 20 years. Managers are consistently calling for better collaboration and researchers have argued that managing tightly coupled relationships creates a co-mingling of complementary competencies that establishes distinctive advantages for firms. Even though there have been a few exemplar companies that have been capable of truly developing these complementary competencies, few companies truly understand the dynamics of a collaborative capability. This dissertation reviews the theoretical conceptualization and operationalization of tightly coupled relationships and through an interpretive analysis, begins to provide clarity to the following questions:

* Under what conditions are tightly coupled …
