Bio-Mass To Bio-Oil: Direct Conversion Vs Companion Coal Gasification, Gabriel Hayes

Honors Theses

Biomass is produced in agriculture and forestry, and can be converted to use as a fuel substitute for petroleum. Direct conversion of biomass to bio-oil is conventionally accomplished with a process called fast pyrolysis, in which the biomass is heated to promote the chemical breakdown of its components. This produces some condensable vapors which, when condensed, yield bio-oil. Such a process was compared to a process that gains heat from companion coal gasification instead of traditional heating media such as heated sand. The conversions were then compared to determine the more cost-effective method for producing bio-oil. Additional parameters investigated include …

Design Of A Carbon Fiber Composite Monocoque Chassis For A Formula-Style Vehicle, Alexander Carline

Honors Theses

Western Michigan University’s Formula SAE team, Bronco Racing, designs and manufactures a formula-style vehicle to compete annually at an international collegiate design and racing competition. In order to remain competitive, Bronco Racing required a lighter chassis for the 2021 vehicle. To achieve this, the full 2020 carbon fiber monocoque chassis system was redesigned to be lightweight while considering packaging constraints, the Formula SAE rules, and design parameters set by Bronco Racing. The monocoque geometry was modeled using SolidWorks and the carbon composite was simulated, tested, and verified using ANSYS and quasi-static load frame testing. The newly designed 2021 monocoque chassis …

Steam Valve Thermo-Performance Analysis, Benjamin Evans

Honors Theses

Steam leaks occur in aging power systems due to heat energy loss in the valves of that system. A model was developed to determine the amount of heat energy lost in Donald C. Cook Nuclear Power Plant’s steam pipe valve system. Several methods were used to determine the mass flow rate and used to model the system in PEPSE. The PEPSE model determined the estimated energy that was lost due to seal leakage and general valve degradation. A program was created for use of plant employees to easily calculate the lost generation in MWe due to these leaks using the …

Cost-Effective Diy Electrometer, Emily R. Johnson

Honors Theses

An electrometer is a critical electrophysiology instrument used to generate minuscule currents for intracellular stimulation of biological neurons. An electrometer also enables simultaneous measurement of the neuron membrane voltage response. This device is necessary to perform accurate stimulation of neurons. However, the cost of commercial electrometers, around $5000, is prohibitive to many researchers, particularly at the high-school or introductory college level. A recent Western Michigan University graduate student, Lucas Essenburg, designed a basic electrometer for $210. His thesis proved that quality electrometers can be constructed for a fraction of the price of commercial-grade equipment.

This project focused on the improvement …

Aerodynamics Of Wind Loading On Buildings, Kayla Burch

Honors Theses

A three-dimensional model of a one-story residential home, with an emphasis on the roof style and structure, was modeled using CATIA and then built and tested in the wind tunnel at Western Michigan University. The wind tunnel allowed an airflow over different style roofs to be tested at 100 mile per hour winds, strengths typical for hurricanes and other natural phenomena. The measured results show the lift and drag, along with the pressure gradient and the skin friction over the roofs. The effect of these aerodynamic characteristics of the building due to adding solar panel prototypes were also evaluated. The …

Understanding Stem Instructors’ Experiences With And Perceptions Of Deaf And Hard Of Hearing Students: The First Step Towards Increasing Access And Inclusivity, Makayla Long

Honors Theses

Through an anonymous survey we analyzed Western Michigan University (WMU) STEM instructors’ experience with and understanding of teaching and interacting with Deaf and Hard of Hearing (HoH) students. The goal of this study was to capture the experiences of WMU STEM instructors and the resources available to them given their direct impact on Deaf/HoH students’ ability to succeed and receive a post-secondary education. The findings of this study support the claim that instructors are not well supported or aware of the needs of Deaf/HoH students, and do not have access to adequate resources to resolve the issue.

The first steps …

Steam Valve Thermo-Performance Analysis, Turner Slaughter

Honors Theses

Steam leaks occur in aging power systems due to heat energy loss in the valves of that system. A model was developed and programmed using Excel to determine the amount of heat energy lost in an aging power plant steam pipe valve system. This model was tested using data from an existing model called PEPSE. The PEPSE model determined the estimated energy that was lost due to seal leakage and general valve degradation. The energy from the steam was quantified using downstream temperature measurement data that was processed with multiple calculation methods to ensure accuracy in the model. The excel …

A Comparison Study Of Naming, Kassidi Krzykwa

Honors Theses

Bidirectional naming is the ability to acquire a listener response or tact for a stimulus and then emit the other operant without further training. Incidental naming refers to the ability to emit the listener response and tact for the item without direct reinforcement after just being exposed to the name of the item. The development of naming could allow a child to learn more readily from the natural environment. However, it is unclear if bidirectional naming and incidental naming are two separate skills, or if one is potentially a prerequisite for the other. For this project, procedures outlined by Greer …

Stimulus Fading On Teaching Receptive Identification, Dennis Pomorski

Honors Theses

Many of the skills needed to live happily and independently are not in the repertoires of children diagnosed with autism, and they do not learn these skills through exposure to others (MacDuff, 2001). One of the skills children diagnosed with ASD struggle to develop is receptive identification. There is often a risk of prompt dependence or failure to transfer stimulus control to the desired stimuli when using LTM prompting methods. Children with autism spectrum disorder may require a different approach in developing a receptive language repertoire. The purpose of this study was to teach a child diagnosed with ASD receptive …

Effects Of Maternal Chemotherapy On Fetal And Childhood Development, Payton May

Honors Theses

The diagnosis of cancer during pregnancy is uncommon. It is estimated that only 3,500 cases of cancer during pregnancy are diagnosed each year, which correlates to one case per 1,000 pregnancies (Pavlidis, 2000). The management of cancer during pregnancy is complex since it involves both the expecting mother and the fetus. Although there are several treatment options available, they are commonly aggressive. The diagnosis of cancer during pregnancy can create dilemmas for patients and health care providers. Pregnant women may be hesitant to receive cancer treatment due to the potential effects it may have on their developing fetus. On the …

Teaching Echoics To A Student With Autism: Video Model Vs Live Model, Dana Waddell

Honors Theses

Learning a language is not always an easy task for all children. Typically, language is a skill that comes naturally very young in a child’s life, but for children with autism, the path to learning language is very different. The first stages of learning language involve many skills, one of which are called “echoic skills,” because the child directly echoes a sound a person elicits. This is fundamental to learning language, especially in children with autism. The field of behavior analysis has conducted great amounts of research on this topic and has found that using technology in therapy sessions can …

Matching-To-Sample Using A Tablet, Karina Salazar-Ponce

Honors Theses

Kids with autism tend to have a difficult time with one-to-one correspondence matching. Matching-to-sample is the process of pairing an identical stimulus to its corresponding stimulus, for example, matching a physical object to its corresponding picture. This is an important skill because it is the first step in teaching individuals with developmental delays visual discrimination skills and generalization of matching. The use of technology is beneficial because it helps with attending in instructional learning. Technology is also becoming more advanced and is being used more in classrooms. The purpose of this study was to teach matching-to-sample using a tablet. There …

Increasing The Echoic Repertoire Of A Child With Autism Using An Imitation And Echoic Sequence, Rose Bridges

Honors Theses

A prerequisite to many things in life is the ability to communicate. Although this may mean many different things, such as verbal language, sign language, written language, and even icons, there must be some form of communication that may be utilized to get needs across. Many young children with autism spectrum disorder (ASD) are non-verbal, however there are also many children with ASD who have the ability to say words but are still not independently speaking. Reinforcing approximations to word sounds has been previously used as an effective way of increasing the child’s verbal repertoire (Shane, 2017). The present study …

Using A Progressive Time Delay To Increase Mands In A Child With Autism, Brielle Babcock

Honors Theses

Mands are a building block for all communication and are therefore important to teach to individuals who do not consistently use mands. Skinner defined a mand as a “verbal operant in which the response is reinforced by a characteristic consequence and is under the control of relevant conditions of deprivation or aversive stimulation” (Hall & Sundberg 1987). By providing individuals with a way to express their desires and needs, individuals display less problem behaviors. A functional form of communication is imperative to typically developing children and children with autism spectrum disorders alike. The goal of the current study was to …

Establishing Auditory Discrimination And Echoic Stimulus Control With An Auditory Matching Procedure, Matthew Von Holst

Honors Theses

An echoic is a verbal operant which is controlled by a verbal discriminative stimulus and is characterized by the repetition of the verbal behavior of another speaker with point-to-point correspondence between the sound of the stimulus and the response (Skinner, 1957). These echoic responses are very important for children with developmental disorders because their language development is very unpredictable and may not appear at all, potentially causing difficulties in school and problems with social development (Reed, 2005). Teaching language acquisition skills can help offset these problems because it reinforces future echoic responses and helps develop advanced verbal operants such as …

"The Tyranny Of The Majority" A Framework Proposal To Assess The Moral Justification Of Voter Identification Laws In The United States, Sally Jordan

Honors Theses

One of the most fundamental rights of democratic citizens is the right to vote. As a result, voters are entitled to equal opportunity to access the polls. Yet recently, states have begun instituting policies that impact individual access to polls, such as voter identification laws.

Since the 2013 dismantling of the Voting Rights Act, 35 states across the United States implemented voter identification laws varying in strictness and the forms of identification they accept. Numerous studies and articles have been written regarding the justification of these voter identification laws in conjunction with their disproportionate effects on certain minorities; however, many …

Nothing Has Changed Since Yesterday, Why The Role Of Social Media In Radicalization Is More Complex Than It Seems, Robert T. Pollard

Honors Theses

In recent years there has been a seeming resurgence of political radicalism such as the alt-right and openly socialist groups that have coalesced around former presidential candidate Bernie Sanders. This sudden resurgence of radicalism has often been blamed on Social Media and its perceived ability to create echo chambers and help these groups organize. The goal of this paper is to refute the idea that social media is the sole cause of this recent wave of radicalism by building a framework of radicalization agnostic of social media, and then to explore how social media interacts with that framework. The paper …

The Effects Of Yoga On Balance For Elementary School Aged Children Receiving Occupational Therapy, Amelia J. Hunley

Honors Theses

Balance is crucial to many daily life activities and is an indicator of independence. The addition of yoga has been shown to improve balance deficits in children, self-reported healthy adults, elderly individuals, and those with Other Health Impairments such as Autism Spectrum Disorder. Yoga is a holistic method, incorporating mind, body, and soul. This holistic method is what occupational therapy operates under as well, allowing the two to work in tandem for the improvement of balance. This study explored the effects of implementing yoga to students receiving occupational therapy services for balance deficits. The Bruininks-Oseretsky Test of Motor Proficiency balance …

Student Attitudes, Collaborative Group Work And Technology Use In Elementary Mathematics Classrooms: Examining Connections, Katie Kukulka

Honors Theses

Understanding how the structure of a group of students impacts how they work together has always been an interesting concept for me, as sometimes my teachers strategically placed certain students with other students, and sometimes we got to choose our seats in class. Recently, I began to focus on how my college peers worked together in groups in my mathematics classes. For example, I noticed how some students would start to lead and take ownership for a group, others would facilitate these group conversations, commenting on the lead students’ suggestions or perhaps recording answers to group work but not necessarily …

Vaccinate Her? I Hardly Know Her!: Understanding Vaccine Hesitancy, Zachary M. Marcum

Honors Theses

Vaccines are a first defense against highly communicable diseases such as measles. For vaccines to protect the population, a vast majority must be vaccinated to maintain herd immunity. Vaccine hesitancy is delaying vaccination from the suggested schedule or refusing vaccination outright. The hesitance is commonly portrayed as a lack of knowledge or scientific literacy. But highly educated people are still just as likely to be hesitant. The basis of hesitance is likely ethically similar to that of vaccination. Understanding the methods of the vaccine hesitant will better inform attempts to persuade them. Individuals have an obligation to the community to …

Developing A Paradigm For The Measurement Of Cortisol, Megan N. Hurley

Honors Theses

Stress is a set of physical and mental states accompanied by specific physiological responses. The psychophysiological activation of stress centers around the hypothalamic-pituitary-adrenal axis, a group of structures that help the body cope with stress. Cortisol is the principle glucocorticoid secreted by the adrenal cortex and is known as a stress hormone. Cortisol allows the body to stay on high alert during the stress response and recording changes in cortisol can be useful in a variety of research studies. This thesis focused on the utility and pitfalls of cortisol testing and research design. Cortisol can be testing through blood, hair, …

Writing Systems As A Reflection Of Ancient Societies, Sarah M. Gripshover

Honors Theses

This thesis examines the writing systems of two ancient societies: the Latin alphabet as a writing system within the Roman Empire and the hieroglyphic writing system within the Maya city-state. This thesis first situates writing as a technology and explains the common uses of writing systems in modern contexts, before turning to an examination of the past. Next, basic literary patterns—including estimated literacy rates, education patterns and opportunities, types of documents, and themes within writing—are examined within the context of both societies. After evaluating these literary patterns, as well as the social, political, and economic organization of both societies, this …

The women who volunteered to participate in this study at Liberty Place had to have at least one child. The six participants were asked eight questions regarding their experiences as a mother at Liberty Place. They were also invited to do a painting activity to create a canvas to honor mothers like them seeking treatment at Liberty Place. This honors thesis highlights issues that arise when a mother is abusing substances. There are countless problems that family members may face when someone …

The Experimental Effects Of Acute Exercise Intensity On Retrieval-Induced Forgetting, Joshua Franklin

Honors Theses

Accumulating research has shown that acute exercise can enhance memory function. Although counterintuitive, acute exercise may also facilitate aspects of forgetting. Specifically, retrieving a subset of items from memory can facilitate the retention of retrieved items (retrieval practice; RP) and inhibit the subsequent retrieval of non-retrieved items (retrieval-induced forgetting; RIF). Given that acute exercise has been shown to enhance cognition-related inhibition, acute exercise may facilitate RIF. A sample of 225 young adults completed either a control (N=75), moderate-intensity acute exercise (N=75), or vigorous-intensity acute exercise session (N=75). Both acute exercise sessions lasted 20 minutes. Participants then completed a standard retrieval-induced …

Teaching Leaders: Culturally Responsive Teaching And The Achievement Gap, Kendall Kern

Honors Theses

As the amount of students in the classroom continues to grow, the achievement gap becomes increasingly larger between white students and students of color across the United States of America. This literature review explores the current literature on how culturally responsive teaching impacts the achievement gap. The achievement gap is defined as the gap in academic performance between white students and students of color. Throughout history, the achievement gap has been enforced and widened by racism, stereotypes, low student engagement, and a lack of critical thinking skills. The literature proves that culturally responsive teaching can increase engagement and critical thinking …

Creating Dynamic Spaces: Exploring Student-Empowered Self-Expression Through Art, Meghan E. Charest

Honors Theses

Research suggests that students living in rural areas may be more likely to face adversity and stress due to intersecting challenges present in their communities including poverty, substance abuse, addiction, poor health, reduced economic opportunity, and geographic isolation. I conducted an engaged scholarship project in partnership with students and staff at JES to explore ways that open-ended art activities that provide students with self-directed creative spaces can cultivate a student-centered environment built around strong relationships. This type of environment can mitigate the negative impacts of adverse childhood experiences potentially affecting rural Maine students and improve a culture of emotional wellness …
