I'M Right Here., Emily Gadzinski

Honors Theses

In order to survive the mundane, monotonousness of my depression, I performed an identity, a repetition of actions and reactions. This performance was the barrier between two selves, my outward expression and my internal experience. “I’m right here”, the title of my exhibition, is my way of asserting and re-claiming my identity. By re-claiming the spaces that my body and mind occupy, I’m able to maintain power and control over my emotional struggle, the perception of myself, and the trajectory of my life. The concept of my thesis was demonstrated through four pieces, which included a video, interactive installation, sculpture, …

Nicholas Of Lyra, Literal Commentary On Galatians, Edward Arthur Naumann

TEAMS Commentary Series

Though little-known today, Nicholas of Lyra's commentaries are arguably among the most widely-read and influential commentaries of all time. For more than two hundred years, from the time of their composition, well into the Reformation era, they were copied and recopied, printed and reprinted, as an indispensable guide to the meaning of scripture. Naumann presents here a complete translation of Lyra's literal commentary on Galatians in English for the first time, with a freshly-edited Latin text, and provides ample notes on its significance in relation to the works of previous authors.

Deep Fluid Inputs Into The Continental-Scale Nubian Sandstone Aquifer System Constrained By Hydrochemical, Stable Isotope, And Noble Gas Data, Abdel Mawgoud Mohammed

Dissertations

The Nubian Sandstone Aquifer System (NSAS) of northeastern Africa is one of the largest confined fossil-water aquifer systems in the world, with several nations relying on it (Egypt, Libya, Sudan and Chad). This groundwater is the biggest and in some cases the only future source of water to meet the development goals of each NSAS country. This study provides new geochemical data from the main oases of the Western Desert of Egypt and a compilation of published hydrochemical data from the regional aquifer. Interpretation of results suggests heterogeneous fluid mixing within the aquifer, the potential for hydrochemical sub-basins, and a …

Studying The Optimum Design Of Automotive Thermoelectric Air Conditioning, Alaa Attar

Dissertations

The remarkable amount of research being conducted on thermoelectrics gives the impression that this technology will have a bright future in power generation and temperature control systems. At the present time, thermoelectrics is applied widely for temperature control, but has not yet replaced conventional air-conditioning systems due to its lower performance. Currently, approximately 10% of annual vehicle fuel consumption corresponds to the air-conditioning system used to cool the vehicle cabin. Conventional air-conditioning systems cool the entire cabin; however, about 73% of a vehicle’s mileage occurs while the driver is the only occupant. These facts indicate the need for a single …

Retention Of Community College Students In Online Courses, Sarah Krajewski

Dissertations

The issue of attrition in online courses at higher learning institutions remains a high priority in the United States. A recent rapid growth of online courses at community colleges has been instigated by student demand, as they meet the time constraints many nontraditional community college students have as a result of the need to work and care for dependents. Failure in an online course can cause students to become frustrated with the college experience, financially burdened, or to even give up and leave college. Attrition could be avoided by proper guidance of who is best suited for online courses. This …

Formulation And Evaluation Of Soy Polymer Based, Gravure Printed Resistive Inks For Applications In Printed Electronics, Bhushan Hiralal Patil

Masters Theses

Today, the majority of the commercially available conductive inks are formulated using expensive metallic particles, such as silver and gold. Most of the inks use volatile solvents in the formulation, which are hazardous to the environment as emission of VOCs is the major concern. In the case of water-based inks, usually petroleum-based acrylic polymers are used. Apart from being nonrenewable raw materials, acrylic polymers are carcinogenic in nature. Also, acrylic polymers are used in a variety of applications, such as the automotive, medical device, paint, and adhesive industries. Often times, the ink industry has to compete with other industries for …

The Relationship Between Counselor Trainees’ Personal Therapy Experiences And Client Outcome, Bonnie L. Vanderwal

Dissertations

Research on mental health professionals’ use of personal psychotherapy indicates that a majority of practitioners have participated in their own personal therapy for both personal and professional reasons (Bike, Norcross, & Schatz, 2009; Norcross & Connor, 2005). Psychotherapists typically suggest that engaging in their own personal therapy has aided in their professional development and clinical effectiveness in their work with clients (Orlinsky, Norcross, Ronnestad, & Wiseman, 2005); however, researchers have been unable to conclude that such evidence exists (Clark, 1986; Greenberg & Staller, 1981; Macaskill, 1988; Macran & Shapiro, 1998; Orlinsky, Norcross et al., 2005). Studies often included psychotherapists already …

Memory Deficits In Older Adults: Evaluating Spaced Retrieval With Multiple Probe Techniques, Christopher Walmsley

Dissertations

Difficulties in recognizing and remembering the names of individuals are a common behavioral symptom of major neurocognitive disorder. A number of behavioral strategies have been proposed to improve memory deficits, including spaced retrieval, an intervention that emphasizes delayed recall of target information. Unfortunately, many of the studies that report beneficial effects of spaced retrieval use a very limited range of outcome measures, thus calling into question the magnitude and generality of any reported memory improvement. This study reports on the impact of spaced retrieval using four older adults with cognitive impairment living in an assisted living facility. All participants demonstrated …

Petrological And Geochemical Evaluation Of The Sturgeon Falls Intrusive Body, Jonathan Michael Haynes

Masters Theses

The Sturgeon Falls Intrusive Body (SFIB) is a gabbroic intrusion located along the Michigan-Wisconsin border just south of the town of Norway, MI. The SFIB is bounded to the north by the Niagara Shear Zone and the Michigamme Formation (Schulz and Cannon, 2006) and to the south by an unnamed thrust fault zone and the Quinnesec Formation (Sims and Schulz, 1993). Field mapping has shown that the SFIB is composed almost entirely of metagabbro metamorphosed to greenschist facies, with isolated outcrops of clinopyroxenite, which are thought to be xenoliths.

The origin of the SFIB is controversial. Schulz and LeBerge (2003) …

An Integrated Framework For Cardiac Sounds Diagnosis, Zichun Tong

Masters Theses

The Phonocardiogram (PCG) signal contains valuable information about the cardiac condition and is a useful tool in recognizing dysfunction and heart failure. By analyzing the PCG, early detection and diagnosis of heart diseases can be accomplished since many pathological conditions of the cardiovascular system cause murmurs or abnormal heart sounds. This thesis presents an algorithm to classify normal and abnormal heart sound signals using PCG. The proposed analysis is based on a framework composed of several statistical signal analysis techniques such as wavelet based de-noising, energy-based segmentation, Hilbert-Huang transform based feature extraction, and Support Vector Machine based classification. The MATLAB …

An Examination Of Academic Grit In Urban High Schools, Ronald Gorman

Dissertations

Currently, in America’s schools, approximately one in five high school students will not graduate with his or her peers, and many others will never receive a high school diploma (Stillwell & Sable, 2013). Many students arrive in our nation’s high schools without the requisite skills to be successful, and when they exhibit failure for the first time, a large percentage of them do not have the passion and perseverance to accomplish their long term goals – otherwise known as “academic grit,” a term coined by Duckworth (2007), a leading researcher in the area.

To investigate the issues mentioned above, a …

Physiological Response To Dissonance In Musicians And Nonmusicians, Angela Beth Biehl

Masters Theses

Knowing the human response to musical dissonance could have important therapeutic implications in the music therapy setting. The listener’s musical experience could significantly impact their response and subsequently its effect in a therapeutic setting. Thus, this study aimed to examine both the psychophysiological and subjective responses to dissonance and the difference in these responses between those with high experience and those with low experience. Participating groups, categorized as high experience (HE) and low experience (LE) in terms of musical knowledge, listened to consonant and dissonant musical excerpts, and rated each excerpt on its pleasantness; their physiologic responses were measured to …

Analyzing Repetitive Sequences With Structured Dynamic Bayesian Networks, Thomas. L. Lake

Masters Theses

Time series often feature structure that is known a priori and easily described using natural language terms such as repetitive, symmetric, seasonal, and self-similar. However, the typical conjugate priors used in Bayesian analysis do not capture such complex phenomena well. As a result of this mismatch, known structure is modeled poorly or completely ignored. Focusing on time series with repetitive structure, this thesis proposes to overcome this problem by reducing rather than in- creasing the capacity of a well know time series model, the Hidden Markov Model. Through a careful choice in the way model capacity is reduced the model …

Design Of Digital Down Converter Chain For Software Defined Radio Systems On Fpga, Nagarjun Marappa

One Good Lesson, Community Of Practice Model For Preparing Teachers Of Writing, Latrise P. Johnson, Elizabeth P. Eubanks

Teaching/Writing: The Journal of Writing Teacher Education

Many writing initiatives have been advocated as ways to improve student writing. However, in order for teachers to successfully teach writing, they must be exposed to a variety of classroom-tested approaches (National Writing Project, 2003).With this in mind, a summer teaching writing course that met at a local high school combined the study of several approaches to teaching writing and field-based teaching and then employed one classroom-tested approach. Using Wenger’s (1998, 2010) communities of practice model, the teaching and learning about writing instruction centered on “practice” within the community and emphasized that preservice teachers act as social participants--that is, meaning-making …

Moving Writing Out Of The Margins In Edtpa: “Academic Language” In Writing Teacher Education, Sarah Hochstetler, Melinda J. Mcbee Orzulak

Teaching/Writing: The Journal of Writing Teacher Education

The edTPA, a standardized teacher performance assessment developed by Stanford University and launched by the Pearson corporation, is quickly becoming a national measure of preservice teacher effectiveness. As more states adopt this assessment as a required component of successful completion of teacher education programs and licensure, we are compelled to critique the design, implementation, and evaluation of this high-stakes testing instrument. Our goal is to articulate the effects of this assessment on writing teacher education and the teaching of writing more broadly. Specifically, we argue that programmatic or individual interpretation of the edTPA can marginalize writing instruction (and writing teacher …

“It Sounds Wrong” Vs. “I Would Be Curious”: Challenges In Seeing Students As Writers In A School-University Partnership, Anne Elrod Whitney, Nicole Olcese, Virginia Squier

Teaching/Writing: The Journal of Writing Teacher Education

This article presents qualitative data and a pedagogical reflection from two teacher educators as they consider a writing partnership between preservice teachers in their methods course and a class of middle school writers. The purpose of the partnership was to help preservice teachers think about students not just for the purposes of evaluation and grading, but as writers, and, more importantly, as human beings. Authors present their inquiry and the challenges that arose as a result of the project, including reflections on the partnership from preservice teachers.
