Chemotypic Variation Of Biogenic Volatile Organic Compounds In Midwest Forest And Atmospheric Role Of Peroxyacyl Nitrates In Southeastern U.S., Shino Toma

Dissertations

Biogenic volatile organic compounds (VOC), including isoprene and terpenes, impact atmospheric processes such as production of tropospheric ozone, formation and growth of secondary organic aerosol (SOA), global climate change, and human health. Although estimated emission rates of total biogenic VOC exceed anthropogenic emissions, there are many challenges to direct measurements because they are very reactive with atmospheric oxidants and some are still difficult to detect by current analytical techniques. Therefore, high uncertainties lead to discrepancies between individual and total biogenic VOC budget with atmospheric oxidants and an underestimation of SOA formation.

White pine (Pinus strobus) was once a dominant species …

Structures Of Metallacarboranes And Coordination Complexes: Coordination Sensors Based On Rhodamine B And Quinolines, Agozie Nnaemeka Oyeamalu

Dissertations

Rhodamine-based ligands that can complex different metals has been designed and synthesized. Using Rhodamine B as starting material, we synthesized and characterized quinoline precursors as well as successfully carried out the oxidation of methyl and aldehyde groups on the quinoline ring, and on the hydroxyl moiety of the quinoline spirolactone ring. These turn-on/off rhodamine fluorescence probes sense Cr³⁺ and Ni²⁺ with high selectivity and sensitivity. These probes can be applied to detect other metal ions that are present in chemical, biological and environmental settings. They were designed to fluoresce when bonded to ions such as cyanide in detecting …

Using Concept Maps To Monitor Knowledge Structure Changes In A Science Classroom, Leah J. Cook

Dissertations

The aim of this research is to determine what differences may exist in students’ structural knowledge while using a variety of concept mapping assessments. A concept map can be used as an assessment which connects concepts in a knowledge domain. A single assessment may not be powerful enough to establish how students’ new knowledge relates to prior knowledge. More research is needed to establish how various aspects of the concept mapping task influence the output of map creation by students. Using multiple concept maps and pre-instruction and postinstruction VNOS instruments during a 16-week semester, this study was designed to investigate …

The overall goal of this study was to understand how metallic pigments in conductive inks in PE are partitioned during landfill disposal and paper recycling conditions. The purpose is to assess the potential environmental impacts of PE landfilling in terms of metal leaching and to help develop new strategies for sequestering metallic ink components while paper-based PE are subjected to conventional paper recycling methods. The objective of this research is to study the fate of …

Development Of Traditional And Rank-Based Algorithms For Linear Models With Autoregressive Errors And Multivariate Logistic Regression With Spatial Random Effects, Shaofeng Zhang

Dissertations

Linear models are the most commonly used statistical methods in many disciplines. One of the model assumptions is that the error terms (residuals) are independent and identically distributed. This assumption is often violated and autoregressive error terms are often encountered by researchers. The most popular technique to deal with linear models with autoregressive errors is perhaps the autoregressive integrated moving average (ARIMA). Another common approach is generalized least squares, such as Cochrane-Orcutt estimation and Prais-Winsten estimation. However, these usually have poor behaviors when fitting small samples. To address this problem, a double bootstrap method was proposed by McKnight et al. …

Rebranding Mediocrity: A Rhetorical Analysis Of Common Core Textbooks For College-Bound Writers, E. Suzanne Ehst

Dissertations

This project analyzes the quality of high school writing textbooks from major publishers, textbooks purported to align with The Common Core State Standards (CCSS) for writing. I measure the textbooks against the promise of CCSS’s tagline, “college and career readiness,” focusing specifically on the former goal to discern how “college-ready writing” is constructed and to analyze the degree to which the textbooks align with relevant research and theory in the fields of English Education and Rhetoric and Writing Studies. I begin the project by situating this study in current U.S. educational policy and rhetoric. Specifically, I describe the politicized rhetoric …

A Meta-Analysis Of Energy Savings From Lighting Programs In Michigan, Teryila Ephraim Amough

Dissertations

In order to fill the gap in aggregates savings, the challenges faced by electric utilities for the demand of lighting energy are addressed by lighting efficiency programs. The shrinking capacity and electrical grid reliability call for improved ways to evaluate energy saving programs with evaluation methods that are robust in determining the impact of lighting programs. This study employed meta-analysis as an evaluation method to determine energy savings, impact, emissions of greenhouse gases (GHG), pollutants, and health effects from lighting programs in Michigan. The findings of the study showed the programs impact in Hedges’ g of 0.36 for the overall …

Time-Dependent Photoionization Of Gaseous Nebulae, Ehab Elsayed Elhoussieny Ahmed

Dissertations

We study time-dependent photoionization of gaseous nebulae, i.e. the physical conditions and spectra of astronomical plasmas photoionized by a time-dependent source of ionizing radiation. Our study proceeds in two chief steps: First, we start with a simplified model of plasmas of pure H. Second, we develop a more realistic model of plasmas composed of a mixture of chemical elements. For the first step, we wrote a time-dependent photoionization code (TDP) that solves the coupled system of equations for ionization, energy balance, and radiation transfer in their full time-dependent forms For the second step, we developed a more realistic code (TDXSTAR) …

The Impact Of Heart Rate Monitor Use On Student Intensity In Elementary Physical Education, Gerrit J. Van Klaveren

Masters Theses

Heart rate monitors (HRM) were used with 80 fifth grade students during an eight-day basketball unit in one elementary school located in Otsego County, Michigan to see if the implementation had any effect on increasing the intensity of the participating students. Specifically, the HRM measured the amount of time the students were engaging in moderate to vigorous physical activity (MVPA). It was hypothesized that with the use of HRM, students would increase their MVPA and maintain that time in MVPA by the eighth day. The eight days were split into four levels where students were introduced to a new feature …

Triplex Enim Eleemosyna Est, Cordis, Oris, Et Operis: Pope Innocent Iii’S Spiritual And Rhetorical Approach To Almsgiving, Thomas J. Maurer

Masters Theses

The Libellus de Eleemosyna is a short work by Pope Innocent III on the topic of almsgiving. Historians have used this "little book" to understand better Innocent‘s thoughts on the virtue. I have discovered, however, that the Libellus was not originally a "little book", but rather a sermon. In this thesis I attempt to describe and understand the Libellus not as a "libellus" but as the preached sermon: Date Eleemosynam. No other historian has approached the Libellus this way. In the first chapter I examine the previous short studies done on the Libellus, how contemporaries viewed Innocent as …

Investigation Of Measured Cane Vibrations For Prediction Of Blind Pedestrian Performance In Surface Preview Tasks, Aaron Dean

Masters Theses

The white cane is the primary navigation tool used by many blind pedestrians, but the basic design of the cane has not changed since the 1940s. A greater understanding of the factors affecting cane performance is essential in improving the design and performance of these canes. One aspect of performance is surface texture discrimination. A study is performed to determine the effect of cane rigidity and cane swipe speed on the ability of a user to select the rougher of two surfaces with different textures. Two methods are developed to select the rougher surface using only the measured cane vibration. …

Optimization And Experimental Application Of Current Stimuli To Leech Pressure-Sensitive Mechanosensory Cells, Alexandra C. Ferguson

Masters Theses

The WMU Neurobiology Engineering Lab has previously utilized a "Reduced Energy Input Stimulus Discovery Method" to compute reduced energy stimuli which evoke desired neuron responses. This approach is based on applying an optimal control method to conductance-based neuron models. Initial experimental feasibility of using the discovered optimal currents has been previously demonstrated using leech pressure-sensitive mechanosensory neurons. This work validates and analyzes experimental application of this method. Based on this analysis, an `informed' neuron model is developed by adjusting parameters to minimize error between results from the informed model and experimental data. The informed model is used to find optimal …

Economic Impact Analysis Of Bridge Construction, Funda Yavuz

Masters Theses

Traffic disruption due to bridge construction has been reduced to several hours with the development of methods characterized as Accelerated Bridge Construction (ABC). Associated risks and additional activities involved with the accelerated construction result in an increased initial project cost. This additional cost is offset by the benefits of reduced mobility impact time such as maintenance of traffic cost, life-cycle cost, and economic impact on surrounding communities and businesses as well as the ability to address seasonal limitations. Traditionally, the savings in user cost from reduced mobility impact time is used to justify the additional cost of accelerated construction implementations. …

The focus of this research project is to create a semi-virtual reality power wheelchair driving simulator that can be used for testing a notch filter for tremors in a safe laboratory environment and obtain data on human operator movements for future mathematical modeling. The simulator incorporates a realistic and immersive virtual environment and power wheelchair movement into it. For the experiment, a physical PWC joystick was connected …

Biological Stress Indicators Among Historically Documented Populations (1913-1935): An Analysis Of Labor Through Entheses And Joint Disease, Anna Paraskevi Alioto

Masters Theses

Recent studies about the American past have aimed to examine multiple lines of evidence to reanalyze the American lived experience. Despite this, there has been limited research conducted using methods from biological anthropology. Skeletal analysis of a sample from the Hamann-Todd Osteological Collection, consisting of individuals (n=118) who lived in Cleveland, Ohio was utilized to understand how the American lived experience impacted the biological stresses of these individuals. The objective was to investigate entheseal changes and degenerative joint disease on the upper limb to reconstruct activity patterns and to test for possible disparities which may represent differing biological stress experiences. …

Tales From The "Bad Ras", Narisse Martin

Honors Theses

The life of a Resident Assistant is anything and everything except dull. From training to duty nights, to suitemate mediations and the end of a contract, each day is a story that most others rarely understand, if it is even believed. From these experiences came a collection of short stories, fictionalized accounts of what it is like to be a Resident Assistant in the average American public university.

For four RAs, the stories of their Residence Life incidents are day in the life for them, even if not the day in the life they expected at the start of the …

Within-Session Progressive Gestural-Prompt Delay To Teach Receptive Identification, Breanne Stiemsma

Honors Theses

Receptive identification skills are important for any child to learn. Without these skills, various aspects of development can become impaired. There are many ways to teach receptive identification. This project pulled ideas from previous studies on within-session progressive gestural-prompt delays as well as the different methods of teaching receptive identification skills, simple-conditional method and the condition-only method. The student was not acquiring receptive identification skills with the traditional methods used in the classroom. Within-session progressive gestural-prompt delay was used in this project to teach receptive identification of objects. An AB single-subject design was used in this project. The student responded …

Explicit Programming For Icon Rings: Visual-Based Discrimination, Samantha Borowski

Honors Theses

Instructional icons are helpful as basic direction following is the basis for complex skills needed later in life. These instructions should have a good training so that children can get the basic skills and can move on to the complex skills. The goal of the project was to increase the correct responses to instructional icons. Visuals are a good tool for learning because it attaches a picture with the event that is happening or will happen. Children with autism sometimes struggle when they are introduced to a new environment so having a system in place to help make instruction following …

Teaching Two Children Diagnosed With Autism To Tolerate Physical Contact, Kelsey Webster

Honors Theses

It was hypothesized that the fading in of a prompt hierarchy coinciding with the delivery of tangibles, edibles, and attention or praise reinforcers would decrease problem behavior and noncompliance in two male children with autism who displayed problem behavior and resistance while being physically prompted. A single-subject research design was used to present the prompt hierarchy across various conditions in a school setting. Both participants initially engaged in problem behavior on 100% of the trials but quickly reduced in intensity of problem behaviors by the end of the intervention. There is no current research conducted on how to decrease problem …

Teaching Imitation To Children With Autism Using Most-To-Least Prompt Fading In Front Of A Mirror, Giulia Avelar

Honors Theses

Children diagnosed with autism spectrum disorder have difficulty acquiring imitative skills, which may serve as an important factor in developing social skills and language (Miller et al., 2015; Ledford & Wolery, 2010; Young et al., 1994). Research has shown that most-to-least prompting is most effective for children who do not learn quickly (Libby et al., 2008). The goal of this study was to discover whether the presence of a mirror affected the rate of acquisition of imitative behaviors compared to a no-mirror condition, using most-to-least within-session prompt fading. This study used a multiple baseline design across sets of behaviors. Sets …

Toilet-Training A Child With Autism In A School Setting, Kristianna Ferrier

Honors Theses

Children with autism and developmental disabilities typically take longer to learn skills. Specific training that requires more repetition to obtain mastery should be used to teach specific tasks (MacDuff, Kratz, & McClannahan, 2001). Toilet training is no exception and must be directly taught to children with Autism. Toilet training is a fundamental skill for independent living and greatly reduces the work load of care givers (Chung, 2007). The child in this study was chosen based on a toilet training readiness checklist. The present study is a combination of the scheduled sitting protocol by Azrin and Foxx (1971) with the omission …

Increasing Shared Attention In Children With Developmental Delays, Shelby Esman

Honors Theses

Joint attention behaviors may be essential to the development of language and social interaction skills (Whalen and Schreibman, 2003). Children with autism spectrum disorder (ASD) often lack these behaviors which may explain the difficulty many of them have communicating appropriately with others (American Psychiatric Association, 2013). Previous research has shown that prompting procedures and social reinforcement have been successful in teaching children with ASD to shift their eye gaze between an adult and the object of interest when prompted to do so (Taylor and Hoch, 2008). This present study set out to create and test a procedure designed to teach …

Using Video Modeling To Teach Functional Direction Following, Breanna Burns

Honors Theses

Many children with developmental disabilities have a hard time learning skills, such as following directions, in a small group setting. Video modeling has been shown as an effective way to teach certain skills to children with autism and other developmental disabilities (Nikopoulos & Keenan, 2004; Wu, Cannella-malone, Wheaton et al, 2016). Little research has been done on using video modeling to teach functional directions. Generalizing direction following skills to appropriate contexts is important for children to be successful in the many environments they encounter in a typical school setting. The purpose of this project was to teach functional direction following …
