Statistical Properties Of Population Stability Index, Bilal Yurdakul

Dissertations

Population stability is an important concept in model management. It is crucial to monitor whether the current population has changed from the population used during development of a model. For example, has the distribution of credit scores changed, and is the existing credit score model still valid? Population change may occur for many reasons–change in the economic environment, strategic change in the business, policy changes within the company, or changes in regulatory environment.

The population stability index (PSI) is a statistic that measures how much a variable has shifted over time, and is used to monitor applicability of a statistical …

Support Assurance-Based Software Development For Mission Critical Domains Using The Model Driven Architecture, Chung-Ling Lin

Dissertations

In the past decades, software development for mission critical applications has drawn great attention not only in various mission critical communities but also software engineering communities. One of the important reasons is that the failure of these systems can lead to some serious consequences such as huge financial loss and even loss of life. Therefore, software certification has become an important activity for mission critical applications in that software assurance for such a system should be certified. With the increasing complexity of a software system in mission critical sectors, certifiers have found hard time to understand how a software system …

Investigation Of Discrete Element Methods For Stud To Turf Interactions, Justin Rittenhouse

Masters Theses

Artificial turf is frequently used in sports today and attempts to advantageously replicate a natural grass/soil playing surface. Despite numerous advantages, the technology is correlated with an increase in injuries. The concept behind this research is to create and validate a discrete element model (DEM) for the ground/foot interaction through the use of open source software. After validation, the goal is to analyze an arrangement of studs to determine what role stud geometry plays on torque [N-mm] and force [N] generation. The validation data was provided through laboratory experiments. Three football studs attached to a rigid bracket were turned at …

Peer And Self Reflective Evaluations; Benefits And Techniques Used In A Middle School Art Room Setting, Mary Garrod

Masters Theses

Students’ intentional development as independent learners is increased with the understanding of self efficacy, which contributes to motivation, persistence for learning, and future achievements. However, adolescence is a time when self efficacy and motivation in art often decline. Two effective teaching and learning practices that can aid middle school art educators in the development of adolescent student judgment skills and confidence as independent learners, are self assessment and peer assessment. This paper presents literature on the topics of peer assessment, self assessment, and their link to self efficacy beliefs in adolescents. It then provides applicable, research-based self and peer evaluation …

Spectral Discrimination Of Phragmites Australis At Different Phenological Stages In Saginaw Bay, Michigan, Trenton Benedict

Masters Theses

Michigan Great Lakes wetlands are among Michigan’s most significant bio-diversified ecosystems. One threat to this ecosystem is invasive species. Phragmites australis is one of these invasive species creating problems in the wetlands. Identifying Phragmites through satellite imagery creates difficulties in discriminating Phragmites from other vegetation accurately. This study used an ASD HandHeld 2 field spectroradiometer to identify the phenological spectral properties between Phragmites and cattails. The Euclidean distance was analyzed the spectral curves from the spectroradiometer to determine the separability between Phragmites and cattails. The largest Euclidean distance determined the best month to separate the spectral signatures of Phragmites and …

From Architectural Design To Structural Analysis: A Data-Driven Approach To Study Building Information Modeling (Bim) Interoperability, Mohammed Aldegeily

Masters Theses

BIM has been playing an essential role in building construction projects in recent years. It was used to automate many tasks such as clash detection, 4D planning, and quantity takeoff, among others. However, the interoperability of BIM still lacks in many fields across the architecture, engineering, and construction domains. This research studies the interoperability between architectural design and structural analysis. The goal is to explore structural analysis of BIM models through data transfer processes between different software platforms via three types of paths: (1) Application Programming Interface (API); (2) “immediately connect,” which is the direct link between software programs from …

Further Development Of A Supervision System For Behavior Analysts To Support Evidence-Based Supervision Practices, Katie Lynn Garza

Dissertations

Effective supervision for individuals seeking certification from the Behavior Analyst Certification Board® (BACB) has been a recent focus in the field of behavior analysis (BACB, 2012). While the organizational behavior management (OBM) literature is rich with evidence for specific performance-improvement techniques, there is a lack of research on supervision systems specifically for supervising individuals seeking to obtain the Board Certified Behavior Analyst (BCBA) credential. Furthermore, studies to date have not examined what it takes for systems to meet their missional objectives while simultaneously providing training and supervision to trainees. This descriptive, process-oriented study sought to analyze the disconnects within a …

Social Comparison Feedback And Goal-Setting Under Fixed Pay And Incentive Pay, Yngvi Freyr Einarsson

Dissertations

The purpose of the study was to compare the effects of graphic social comparison feedback (SCF) with tiered goals under both fixed pay and incentive pay. Graphic SCF that displays the individual performance of each group member was found to be the most effective type of graphic feedback in two relatively recent studies (Einarsson, 2016; VanStelle, 2012). The effectiveness of SCF may be due to the fact that the performances of peers serve as sub-goals for each individual, essentially setting up individualized ability-based goals. Currently, it is unclear whether the normative component of SCF contributes to its effectiveness. Rather, similar …

Teaching Eye Contact And Responding To Name To Children With Autism Spectrum Disorder, Amelia M. Fonger

Dissertations

Eye contact and responding to name may be described as behavioral cusps because acquiring these skills extends contact with the environment, can allow behavior to come under the control of new contingencies, and may facilitate the acquisition of new behavior (Bloom & Lahey, 1978; Carbone, O’Brien, Sweeney-Kerwin, & Albert, 2013; Cook et al., 2017; Hanley, Heal, Tiger, & Ingvarsson, 2007; Rosales-Ruiz & Baer, 1997; Tiegerman & Primavera, 1984; Weiss & Zane, 2010). Eye contact and responding to name are commonly cited as targets for early intensive behavioral intervention; however, the existing literature is limited in its ability to guide a …

Assessment For Mild Cognitive Impairment: Striving For Best Practice, Julie Leigh Dalmasso

Dissertations

This dissertation is a series of three studies aimed at determining the best assessment practices for mild cognitive impairment (MCI) that can employed by speech-language pathologists (SLPs). The first study was non-experimental and descriptive examining whether three commonly used assessment instruments yielded similar categorical results. The data were analyzed to determine whether the Eight-Item Interview to Differentiate Aging and Dementia (AD8), the Mini-Mental State Examination (MMSE), and the Cognitive-Linguistic Quick Test (CLQT) identified the same participants from a neurotypical sample as having cognitive deficits. Very little agreement was found amongst the three tools.

Study two was modified to include two …

Application Of Response-To-Intervention In A Pre-Kindergarten Special Education Classroom, Justin J. Daigle

Dissertations

Lovaas (1987) applied behavior analysis to the treatment of autism and demonstrated a 47% “recovery” rate. He also reported that around 10% of the population that received his services made little-to-no improvement. The present study used a response-to-intervention framework to systematically identify and treat students in an early childhood, special-education classroom who were in danger of falling within that 10%. This study set out to identify, classify, and differentiate the treatment based on the student’s response to the standard classroom intervention. Improvements in multiple students’ rates of acquisition based on this system were recorded. This indicated a possibility of improved …

Web-Based Stimulus Preference Assessment And Reinforcer Assessments For Videos, Hugo Curiel

Dissertations

Stimulus preference assessments and reinforcer assessments are integral components of positive reinforcement-based interventions. Web-based brief multiple-stimulus without replacement (MSWO) preference assessments have recently been shown to be effective in identifying preference hierarchies for videos (Curiel, Curiel, Li, Deochand, & Poling, 2018). The purpose of the current studies was to replicate Curiel et al.’s web-based MSWO assessment and assess the reinforcing function of the highest and lowest identified stimuli using novel web-based reinforcer assessments. Study 1 employed single-operant arrangements (SOAs) and Study 2 employed concurrent-operants arrangements (COAs) to assess the absolute and relative reinforcing function of the identified stimuli, respectively. The …

A Holistic Computational Approach To Boosting The Performance Of Protein Search Engines, Majdi Ahmad Mosa Maabreh

Dissertations

Despite availability of several proteins search engines, due to the increasing amounts of MS/MS data and database sizes, more efficient data analysis and reduction methods are important. Improving accuracy and performance of protein identification is a main goal in the community of proteomic research. In this research, a holistic solution for improvement in search performance is developed.

Most current search engines apply the SEQUEST style of searching protein databases to define MS/MS spectra. SEQUEST involves three main phases: (i) Indexing the protein databases, (ii) Matching and Ranking the MS/MS spectra and (iii) Filtering the matches and reporting the final proteins. …

Statistical Models For Correlated Data, Xiaomeng Niu

Dissertations

Correlated data arise frequently in many studies where multiple response variables or repeatedly measured responses within subjects are correlated. My dissertation topic lies broadly in developing various statistical methodologies for correlated types of data such as longitudinal data, clustered data, and multivariate data.

Multiple response variables might be relevant within subjects. A univariate procedure fitting each response separately does not take into account the correlation among responses. To improve estimation efficiency for the regression parameter, this study proposes two estimation procedures by accommodating correlations among the response variables. The proposed procedures do not require knowledge of the true correlation structure …

Investigating Generalization Of Motorist Yielding To The Gateway Prompt From The Treated Leg Of The Intersection To The Untreated Adjacent Leg, Brian J. Crowley-Koch

Dissertations

Pedestrian safety continues to be an important research topic, especially since recent data show a small increase in pedestrian fatalities (USGAO, 2015). There have been several interventions that prompt pedestrians, but especially motorists, to yield properly at uncontrolled crosswalks (Van Houten, 1988; Van Houten & Malenfant, 1992; Nasar, 2003; Crowley-Koch, Van Houten & Lim, 2008). One low-cost intervention that has been successful is the R1-6 in road yielding sign (Kannel, Souleyrette, & Tenges, 2003). When this sign is laid out purposefully across a crosswalk (called a gateway), it has resulted in substantial increases in yielding compared to baseline conditions. In …

Sacrificial Dynamite: The Convergence Of Developed Empathy And Ongoing Relational Experience With God: A Grounded Theory, Toran Scott

Dissertations

This grounded theory study examined how participants described and reflected on their lives and what led them to choose sacrifice. The study was grounded in a Christian understanding of sacrifice, defined as the willful giving up of one’s positions or possessions for the sake of serving others. Using in-depth, open-ended interviews and follow-up interviews to co-construct meaning, participants were asked to reflect on their childhood, adolescence, and emerging adulthood to reflect on and describe any messages, relationships, or experiences that they thought contributed to their eventual choice to sacrifice. The interviews were free-flowing and filled with beautiful and engaging stories. …

Power-Efficient And Highly Scalable Parallel Graph Sampling Using Fpgas, Muhammad Usman Tariq

Masters Theses

Energy efficiency is a crucial problem in data centers where big data is generally represented by directed or undirected graphs. Analysis of this big data graph is challenging due to volume and velocity of the data as well as irregular memory access patterns. Graph sampling is one of the most effective ways to reduce the size of graph while maintaining crucial characteristics. This thesis presents design and implementation of a field programmable gate array (FPGA) based graph sampling method which is both time- and energy-efficient. This is in contrast to existing parallel approaches which include memory-distributed clusters, multicore and GPUs. …

Further Exploration Into The Coma Recovery Scale - Revised And The Music Therapy Assessment Tool For Awareness In Disorders Of Consciousness, Alika D. Seu

Masters Theses

Due to the high rate of misdiagnosis of individuals with disorders of consciousness (DOC) it has been a priority to develop clinical tools to accurately diagnose and assess these individuals (Seel et al., 2010). The Coma Recovery Scale – Revised has been regarded as the gold standard assessment for this population, however, a recent pilot study has shown that the Music Therapy Assessment Tool for Awareness in Disorders of Consciousness (MATADOC) may have increased sensitivity in several assessment domains (auditory, visual, arousal, and verbal commands) in relation to the overall diagnostic outcome. The data sets from this pilot study were …

Stifling The Subversive Swing: An Austrian Perspective On The Nazi Jazz Ban, Colin J. Rensch

Masters Theses

This research investigates the rationale behind the Nazis’ suppression of jazz music during the Second World War. Existing scholarship explains the circumstances surrounding this suppression, but it does not explore why the Nazis did not completely eradicate jazz. The goal of this research is to reveal which aspects of jazz the Nazis particularly disdained and why they allowed this music to continue while they so vehemently suppressed other forms of art that they deemed undesirable.

In order for the arguments to be viewed in their proper context, the thesis first discusses the rise of jazz in Austria and the Austrian …

Determinants Of Household Water Use In The City Of Kalamazoo, Michigan: The Role Of Climate And Socioeconomic Factors, Danielle Molenaar

Masters Theses

Located in the Great Lakes Watershed, the City of Kalamazoo can be considered “water rich”. Therefore, the area has been absent from water use studies. Water use studies are beneficial in all locations; as they can aid city planners, water resource managers, and utility companies. This study examines how household monthly water use in the City of Kalamazoo is impacted by both climate and socioeconomic variables over the period 2006-2016. Household level data were aggregated into census tracts to obtain monthly tract averages for the eleven-year period. Ordinary least squares regression (OLS) was used to determine which variables impact the …

Characterization Of Pinitol Catabolism In Sinorhizobium Meliloti And Its Role In Nodule Occupancy, Angela Irene Kennedy-Mendez

Masters Theses

Sinorhizobium meliloti, which is the nitrogen fixing symbiont of Medicago sativa (alfalfa), was used to test the hypothesis that D-chiro-inositol is an intermediate of pinitol catabolism and that pinitol catabolism plays a role in S. melilot s ability to compete for nodule occupancy. An analytical method, involving gas chromatography and mass spectrometry (GCMS), was developed to detect and separate pinitol and D-chiro-inositol. The S. meliloti wild type, and three isogenic mutant strains (idhA, mocD, and mocE) were grown in minimal medium with pinitol and pinitol plus glycerol. The S. meliloti wild type can utilize pinitol as a sole carbon source, …

Effect Of Social Feedback On Emotions And Preferences In Music, Megan Dillon

Masters Theses

The purpose of this research project was to investigate whether social feedback had an effect on individuals’ emotional ratings of and preferences in music. The current study recruited 173 participants and was based on a study by Egermann, Grewe, Kopiez, and Altenmüller (2009a) that surveyed individuals on their reactions to music when presented with falsified social feedback. The research hypothesis was that participants who were exposed to manipulated social feedback would report emotional ratings and preferences more closely aligned with the social feedback than when not exposed to the feedback. Results showed significant differences in participants’ reported ratings of music …

The Role Of Arts Education In Closing The Achievement Gap In High Poverty Schools, Deanne Basse

Masters Theses

This paper will review research that identifies different types of poverty and how brain development may be affected as a result of living in poverty. Although research reflects support and understanding by the American people that arts education is important to the well roundedness of youth and, in fact, correlates with higher standardized test scores, arts programs continue to be cut especially in areas of poverty. There is an achievement gap in educational success when it comes to students that live in poverty and that of students in higher socioeconomic situations. Students of poverty are working with increased internal and …

Teaching The Soft Skills Through The Arts: A Supplementary Art Curriculum, Brittany Boverhof

Masters Theses

Soft skills are the ability to work with, for, and among other people, yet we can no longer expect students to develop these skills organically. This research builds on the knowledge that if we want the students we are educating to be successful in employing their own soft skills, then they must be taught. This paper defines soft skills, shows their importance, and introduces practices that are proven to build soft skill ability. I have constructed twelve lesson plans that teach the soft skills through experientialism, working in groups, art, critique, classroom management, and problem solving. This supplementary curriculum provides …

Punks In The Church: The Relationship Between The Punk Subculture And Church In East Germany, Ruth A. Aardsma Benton

Masters Theses

A punk subculture emerged in East Germany during the late 1970s and early 1980s. It was an expression of their disillusionment with life, their frustrations with the government, and their pessimistic view of a future that seemed pre-planned. The subculture refused to conform, disengaged from the established system, and expressed their views through song lyrics and other acts of defiance. In the eyes of the state, punks were a threat. The subculture turned to the East German Protestant churches for shelter. The churches occupied a unique place within East German society because the government had granted the churches limited free …
