Tongs: Tldr; Opinion Network Guide System, Andrew Jen Wang
Master's Theses
In the modern world, huge amounts of text are being generated every minute. For example, Twitter users post their current emotions in tweets, while Facebook users vent about their experience in posts. In just one minute, Twitter users upload 350,000 tweets, and Facebook users post anywhere from 2.5 million to 3 million posts. To keep up with this growth in data, almost all of this information goes through automated text processing. To extract features such as the opinion and subjectivity in text, sentiment analysis is applied to the corpus. In this thesis, we present the TONGS library for conducting sentiment …

In her lifetime, Lois Lenski wrote, illustrated, and otherwise contributed to more than one hundred books for children and preteens. This study focuses on Lenski’s regional books for preteens, novels that Lenski claimed were written from real life. Using interpretive narrative analysis, this study evaluates two of Lenski’s regional novels: Strawberry Girl (1945), the 1946 Newbery award-winner and second installment in the American Regional series, and High-Rise Secret (1966), the eleventh installment in the Roundabout America series, focusing specifically on Lenski’s creative process. The analysis of Lenski’s works was contextualized using literature focusing on the concepts of character representation, authority, …
The Utility Of Foraminifera In Documenting Sediment Provenance For Overwash Deposits: A Case Study Using Sediments Deposited By Tropical Cyclone Pam In Vanuatu, Thomas Kosciuch
Master's Theses
Tropical cyclone inundation is a major threat to the highly exposed islands of the South Pacific. This vulnerability was highlighted in March 2015 when Tropical Cyclone (TC) Pam made landfall on Vanuatu as a Category 5 storm, impacting coastlines with storm surges that produced high water marks up to 7 m above MSL and deposited sediments up to 400 m inland. We examined the foraminiferal assemblages contained within TC Pam sediments at two locations in Vanuatu: a mixed-carbonate embayment (Manuro), and a volcaniclastic beach (Port Resolution Bay; PRB). At Manuro, the TC Pam sediments were up to 10 cm thick …

Master's Theses
Using a sample of 251 college students, it was found that 1) when differentiation (D) of work values was calculated using three indices, high-low D, Iachan D, and variance D, only Iachan D positively related to indecision but high-low D and variance D did not, 2) none of the three indices of D related to career maturity, 3) work values profile elevation (PE) positively related to extraversion, openness, and negatively related to depressive symptoms and career indecision but was unrelated to career certainty and neuroticism and 4) work values PE moderated the relationship between Iachan D and career indecision. The …
Development Of An Improved Synthesis Of S-D-Ribosyl-L-Homocysteine (Srh) And Progress Toward Srh Analogs Modified At The C3 Position, Emily Rouse
Master's Theses
Quorum sensing is a system that facilitates bacteria turning on and off gene expression depending on population density. System 2 quorum sensing is utilized by both Gram positive and Gram negative bacteria, and the quorum sensing molecule used in this system is AI-2. AI-2 is biosynthesized by the enzyme LuxS from the precursor SRH. This thesis describes an improved synthesis of SRH through the exploration of different protecting group strategies. The knowledge gained from the improved synthesis of SRH is then applied toward the synthesis of SRH analogues with increased steric bulk installed through use of a stereoselective anti-Mannich reaction. …
The Effects Of Real-Time Visual Performance Feedback Using A Tier Approach For Increasing Behavior Specific Praise On Teachers, Elizabeth Lown
The Effects Of Real-Time Visual Performance Feedback Using A Tier Approach For Increasing Behavior Specific Praise On Teachers, Elizabeth Lown
Master's Theses
A number of studies have found behavior specific praise to be effective in increasing academically engaged behaviors and decreasing disruptive behaviors of students. The proposed study evaluated the effects of real-time visual performance feedback as a strategy for promoting teacher use of behavior-specific praise. An ABCBC design was utilized to determine the efficacy of real-time visual performance feedback in comparison to delayed visual performance feedback. The primary dependent variable measured was teacher use of behavior-specific praise. Additionally, student outcomes were assessed to determine the relationship between teacher use of behavior-specific praise and student behavior. The results from the study provide …

Women In Wartime Shipyards: Operating A Drill Press Was Like Using An Egg Beater, Carol A. Strohmetz
Master's Theses
This research examines the duality of the roles of American women during World War II. The research draws upon oral histories, newspaper accounts and advertisements, music and films of the time, letters and family scrapbooks, and primary and secondary sources. Most prior research focuses on either women in the workforce or women in the home. This research synthesizes all aspects of the lives of women as they navigated the hostile terrain of the male workforce and continued to perform the duties assigned to them by society. This research highlights the multiple roles that women successfully executed as they cared for …
The Influence Of Talker Expectations And Acoustic Variability On Speech Perception In Asd, Anders Hogstrom
The Influence Of Talker Expectations And Acoustic Variability On Speech Perception In Asd, Anders Hogstrom
Master's Theses
Speech perception is dependent upon the ability to map the sensory features of a speech signal onto the perceptual features which make up language (i.e., phonemes). A great deal of research over the past six decades has focused on how variability across talkers influences speech processing. Listeners are required to normalize the acoustic variability across talkers by continuously updating the mapping from the acoustic signal to phonetic representations. As such, processing speech from multiple talkers is cognitively more demanding than listening to a single talker. This processing cost appears to reflect, in part, the influence of listeners’ expectations that speech …
Towards Efficient Computation In Real-Time Systems, Hamza Omar
Towards Efficient Computation In Real-Time Systems, Hamza Omar
Master's Theses
Graph algorithms have gained popularity and are utilized in high performance and mobile computing paradigms. Input dependence due to input graph changes leads to performance variations in such algorithms. The impact of input dependence for graph algorithms is not well studied in the context of approximate computing. This thesis conducts such analysis by applying loop perforation, which is a general approximation mechanism that transforms the program loops to drop a subset of their total iterations. The analysis identifies the need to adapt the inner and outer loop perforation as a function of input graph characteristics, such as the density or …
Alternative Mission Concepts For The Exploration Of Outer Planets Using Small Satellite Swarms, Andrew Gene Blocher
Alternative Mission Concepts For The Exploration Of Outer Planets Using Small Satellite Swarms, Andrew Gene Blocher
Master's Theses
Interplanetary space exploration has thus far consisted of single, expensive spacecraft missions. Mission costs are particularly high on missions to the outer planets and while invaluable, finite budgets limit our ability to perform extensive and frequent investigations of the planets. Planetary systems such as Jupiter and Saturn provide extremely complex exploration environments with numerous targets of interest. Exploring these targets in addition to the main planet requires multiple fly-bys and long mission timelines. In LEO, CubeSats have changed the exploration paradigm, offering a fast and low cost alternative to traditional space vehicles. This new mission development philosophy has the potential …
#Sayhername: Negotiating Issues Of Victimhood, Violence, And Visibility, Carol Ann Jackson
#Sayhername: Negotiating Issues Of Victimhood, Violence, And Visibility, Carol Ann Jackson
Master's Theses
This thesis analyses both news articles and tweets discussing #SayHerName and both implicit and explicit discussions of race, gender, and sexuality. Prior research on media representations of race, gender and violence has found that black women have been denied visibility as victims in unilateral media portrayals of gendered violence, which has contributed to the social problem of black women’s marginalization as their experiences of injustice become invalidated. This denial is not directly stated, rather it functions through a use of controlling images which reproduce racist, sexist, and heteronormative media messages by naturalizing black women as devious, promiscuous, and aggressive. This …
Evaluating The Success Of Making Equitable, Predictable, And Transparent Development Decisions By Encouraging Community And Stakeholder Collaboration Through Two Participatory Design Case Studies, Samantha Stewart
Master's Theses
The purpose of this thesis is to use participatory design strategies throughout the design process in order to make fair, transparent, and successful design outcomes. Participatory design is an approach that encourages actively involving all stakeholders, clients, community members, and site users to make sure the solution meets their desires and needs. This approach is used in two community based projects; the Ecological Screen in Fairfield, CT and Wolcott Park in West Hartford, CT. For my research I completed a series of stakeholder and client meetings, public workshops, and surveys in order to educate the public and build a strong …

Background: Recent studies on Pre-exposure prophylaxis treatment (PrEP) has received significant recognition as a promising preventive strategy among high-risk individuals. Although a significant amount of research has been conducted on willingness of PrEP use, and NCI as predictors of HIV risk behavior, no study to date, has explored the impact of various motivation factors along with the use of internet & technology devices and psychological aspects on PrEP adherence self-efficacy. So, the objectives of thesis analyses were to examine whether various motivation factors, psychological factors, and communication technology predicts PrEP adherence self-efficacy. Method: The study was conducted among 400 HIV-negative …
Early Empirical Evidence For The Effects Of Adaptive Ramp Metering On Measures Of Travel Time Reliability, Travis Charles Low
Early Empirical Evidence For The Effects Of Adaptive Ramp Metering On Measures Of Travel Time Reliability, Travis Charles Low
Master's Theses
Adaptive ramp metering (ARM) is a critical component of smart freeway corridors under an active traffic management portfolio. While improving capacity through smart corridors and application of proactive traffic management solutions is less costly and easier to deploy than freeway widening, conversion to smart corridors still represents a sizable investment for a state department of transportation. Early evidence of improvements following these projects can be valuable to agencies. However, in the U.S. there have been limited evaluations, of smart corridors in general and ARM in particular, based on real operational data. This thesis explores travel time reliability measures for the …
3-D Coverage Path Planning For Underwater Terrain Mapping, Zongyuan Shen
3-D Coverage Path Planning For Underwater Terrain Mapping, Zongyuan Shen
Master's Theses
This thesis presents an autonomous approach of 3-D coverage of underwater terrain using multi-level coverage trees. An autonomous underwater vehicle (AUV) equipped with multi-beam sonar sensors, Doppler velocity log (DVL) and inertial measurement unit (IMU) sensors is used to achieve this goal. The underwater 3-D search space is represented by a multi-level coverage tree which is generated online based on the obstacle information collected by the AUV. The nodes of the tree correspond to safe sub-areas for AUV navigation which are identified based on obstacle density in neighborhood of free cells. Standard tree traversal strategies like depth-first-search (DFS) and breath-first-search …
The Role Of Bmp Signaling In Mediating Stimulatory Effects Of Fgf-Fgfr Signaling On Odontoblast Differentiation In Dental Pulp, Karen Sagomonyants
The Role Of Bmp Signaling In Mediating Stimulatory Effects Of Fgf-Fgfr Signaling On Odontoblast Differentiation In Dental Pulp, Karen Sagomonyants
Master's Theses
Odontoblast differentiation is dependent on multiple signaling molecules, including growth factors stored in the extracellular dentin matrix. Our previous studies have demonstrated that Fibroblast Growth Factor 2 (FGF2) exerted stage-specific effects on odontoblast differentiation in primary dental pulp cultures. FGF2 stimulated differentiation of functional odontoblasts expressing high levels of Dmp1 from early progenitors but inhibited the terminal differentiation of functional odontoblasts to fully differentiated odontoblasts expressing high levels of Dspp. These stimulatory effects involved activation of FGFR and ERK1/2, and increased levels of expression of Bmp2, Runx2, and Osx (components of BMP signaling) suggesting the involvement of …
Effects Of A Standardized, Freeze-Dried Grape Powder In Adults With Metabolic Syndrome, Quinn Duclos
Effects Of A Standardized, Freeze-Dried Grape Powder In Adults With Metabolic Syndrome, Quinn Duclos
Master's Theses
Diets rich in fruits and vegetables have been correlated to lower disease risk. This is thought to be due to bioactive components such as: vitamin C, vitamin E, carotenoids, and polyphenols. Grapes are a food source of many bioactive components, including polyphenols. The effects standardized, freeze-dried, grape powder (GRAPE) were examined in adults with metabolic syndrome (MetS). Twenty men and women (aged 30-70 y) were instructed to consume 60 g/day of GRAPE (equivalent to 2.5 cups fresh grapes daily) or nutritionally-matched placebo powder in a randomized, placebo-controlled, crossover intervention study for 13 weeks. This included 2-week run-in, 4-week intervention (GRAPE …
Determinants Of Tree Sway Frequency In Temperate Deciduous Forests Of The Northeast United States, Amanda Bunce
Determinants Of Tree Sway Frequency In Temperate Deciduous Forests Of The Northeast United States, Amanda Bunce
Master's Theses
Trees are the most common cause of utility damage and power outages during storms in the northeastern United States. Previous studies on tree sway and risk-of-wind-throw have largely been conducted in heavily managed, even-aged, monospecific coniferous stands, while relatively little is known for northeastern mixed temperate deciduous forests. Past studies have suggested a relationship of fundamental vibrational frequencies (FVF) to wind-firmness. The objective of this study was to identify factors determining tree sway frequency in temperate deciduous forests from characteristics of tree architecture, stand structure and wind conditions. To this end, the motion of 41 trees across nine different species …

Investigating Program Evaluation Implemented By Rural Education Systems To Determine The Efficacy Of Speech-Language Telepractice Services, Allyson Doreen Montgomery
Investigating Program Evaluation Implemented By Rural Education Systems To Determine The Efficacy Of Speech-Language Telepractice Services, Allyson Doreen Montgomery
Master's Theses
Given the importance of providing speech-language services to students in rural areas, school districts have begun adopting telepractice as a primary service delivery model (American Speech-Language and Hearing Association [ASHA], n.d.b; Forducey, 2006; & Polovoy, 2008). However, as the demand for telepractice grows, so does the need for a strong method of program evaluation (ASHA, 2005a). The purpose of this study was to investigate the methodologies district level administrators use to evaluate effectiveness and ensure the validity of telepractice services. Two district level administrators from distinct rural educational cooperatives participated in this study. Both were from two distinctive Midwestern states …

The current study aims to examine the influence of parent-child sexual communication on adult sexual communication when those children reach adulthood and engage in romantic relationships. Parent-child sexual communication, attachment styles, sexual attitudes, and partner sexual communication were examined for influence on the physical and emotional relationship satisfaction of emerging adults. Study 1 included a quantitative analysis with 553 emerging adults participating in an online survey, and study 2 incorporated a qualitative analysis with an additional 7 emerging adults participating in online …
For King And Country: Reconsidering The Great War Soldier In Britain, 1914-1945, Nicholas John Schaefer
For King And Country: Reconsidering The Great War Soldier In Britain, 1914-1945, Nicholas John Schaefer
Master's Theses
In the postwar period historians argued that the horrors of the First World War created an irreparable disconnect between soldiers’ pre and postwar lives. Scholars led by Paul Fussell and Eric Leed presented the Great War as a futile waste of life for a meaningless cause. This historiography argues that the generation which survived the Western Front returned to Britain as jaded shells of their former selves unable to relate to their old lives and families. Bitterness and apathy replaced belief in cause and country. In contrast, recent historiography asserts that British soldiers maintained belief in their country’s cause and …
Biodiversity And Phenology Of The Epibenthic Macroinvertebrate Fauna In A First Order Mississippi Stream, Jamaal Bankhead
Biodiversity And Phenology Of The Epibenthic Macroinvertebrate Fauna In A First Order Mississippi Stream, Jamaal Bankhead
Master's Theses
I used Hester-Dendy multiplate samplers and stick and leaf samples to collect the aquatic insects of Granny Creek, a first-order perennial stream in southern Mississippi, on twelve sampling dates from March 2014 to June 2015. The dominant insect/invertebrate group in Granny Creek was the dipteran family Chironomidae. Forty-two distinct taxa of chironomid larvae were collected over the duration of my study. Two of the dominant chironomid subfamilies in my samples, the Orthocladiinae and the Chironominae, displayed a phenological pattern in which the Orthocladiinae were more prevalent, both in terms of number of species and in abundance of individuals, in the …
Austin (22tu549): Mississippian Emergence In The Northern Yazoo Basin, Elizabeth Kay Hunt
Austin (22tu549): Mississippian Emergence In The Northern Yazoo Basin, Elizabeth Kay Hunt
Master's Theses
The Austin Site (22TU549) is a known transitional Late Woodland to early Mississippian village located in Tunica County, Mississippi. Compared with the cultural phases that have been developed in other regions the northern Yazoo Basin lacks a clearly defined “Emergent Mississippian” phase. This study examined the ceramic assemblage (n=30,567) from a 25% random sample of pit features to measure transitional change as a way to define an early Mississippian phase. It also explored the ways in which this site experiences the Mississippian transition and how it fits into the larger trajectory of the Mississippian phenomenon in the Southeastern United States …
Black And Blue: Competing Social Constructions Of Police On Instagram And Twitter, Mary Frances Thornhill
Black And Blue: Competing Social Constructions Of Police On Instagram And Twitter, Mary Frances Thornhill
Master's Theses
Mass media outlets newspapers and television were traditionally where individuals gathered their news information; however, with the growth of new media platforms like Twitter, Facebook, and Instagram, individuals are now co-producers of the content that is seen by the public. Previous research indicated that media-generated images of the police influence public perception and that new media outlets are becoming increasingly influential, particularly in regards to social and political conflicts. This means that research on the role of new media outlets in socially constructing reality is essential, though not much of this research has yet been completed. This current analysis fills …
"There Was No Sign Of Man In It": Casting Dracula As Posthuman And Valuing The Progressive Vampire, Mary Elizabeth Wolverton
"There Was No Sign Of Man In It": Casting Dracula As Posthuman And Valuing The Progressive Vampire, Mary Elizabeth Wolverton
Master's Theses
Although not an immediate commercial success, Dracula has since become a seminal example of Gothic horror at the fin-de-siècle, leading not only to film, stage, and television adaptations, but also to literary reimaginings and a plethora of scholarship. I argue that the vampires in Dracula do not fit into the traditional critical understandings of the vampire; rather, they belong in two different but related categories recently theorized by science fiction studies and related to human evolution: transhuman and posthuman. I suggest that a reading of the novel that prioritizes the pervasive influence of evolutionary theory on Victorian literature encourages …
A Close Encounter With Death: Narration In Markus Zusak's The Book Thief, Erin M. Gipson
A Close Encounter With Death: Narration In Markus Zusak's The Book Thief, Erin M. Gipson
Master's Theses
While critics have discussed Markus Zusak’s The Book Thief (2005) in terms of the Holocaust, its generic hybridity, and its crossover readership for child and adult audiences, I offer the first narratological reading of its unusual narrator: Death. This reading focuses on the rhetorical strategies underlying Death’s contradictory narration, which is at once anthropomorphized and constitutively nonhuman. Scholars of The Book Thief often assume the narrator’s omniscience, but I find that Death is crucially not omniscient; rather, he merely performs omniscience to mask his humanlike limitations. Since current terminology falls short of describing Zusak’s narration, I propose the new classification …
How Did We Get Here? An Inquiry Into Pop Culture, Pop Culture Icons, And America's Support Of The Degradation Of Humanity Through Mass Media Consumption, Thomas Steele
Master's Theses
This thesis focuses on the contemporary human condition associated with the consumption of current entertainment media. Sampling on modes of thought from anthropological, biological, psychological, sociological, and biographical points of view I sought to define what it means to be uniquely human. Furthermore, I sought to compare and contrast contemporary human interactions as described through research studies associated with tabloid news sources, and the entertainment industry. The results of this study were then articulated through four works of art that visually describe that which was found amongst a variety of resources. They describe the rise and fall of the careers …
Effects Of A Function-Based Peer Management Intervention With Middle-School Students With Adhd, Kate A. Helbig
Effects Of A Function-Based Peer Management Intervention With Middle-School Students With Adhd, Kate A. Helbig
Master's Theses
Attention Deficit/Hyperactivity Disorder (ADHD) is characterized by impairment in functioning due to inattention, hyperactivity, or impulsivity, as well as difficulties in school with social rejection and academic underachievement (American Psychiatric Association, 2013). The purpose of this study was to investigate the effectiveness of a peer-mediated non-contingent reinforcement (NCR) intervention informed by functional assessment data to decrease disruptive behavior for students with a special education classification of OHI-ADHD. Participants included three student dyads in a middle school setting located in the Southeastern United States. An A/B/A/B withdrawal design was used to evaluate the effectiveness of this intervention. The primary dependent variables …
