Thermo-Chemical Conversion Of Coal-Biomass Blends: Kinetics Modeling Of Pyrolysis, Moving Bed Gasification And Stable Carbon Isotope Analysis, Abhijit Bhagavatula

Theses and Dissertations--Chemical and Materials Engineering

The past few years have seen an upsurge in the use of renewable biomass as a source of energy due to growing concerns over greenhouse gas emissions caused by the combustion of fossil fuels and the need for energy independence due to depleting fossil fuel resources. Although coal will continue to be a major source of energy for many years, there is still great interest in replacing part of the coal used in energy generation with renewable biomass. Combustion converts inherent chemical energy of carbonaceous feedstock to only thermal energy. On the other hand, partial oxidation processes like gasification convert …

Public Wars, Private Warriors: An Analysis Of Private Military Contractors In American Foreign And Domestic Policy, Phillip Andrew Roughton

Masters Theses

At the end of the Cold War, the global political arena was forever altered. One of the major changes was the introduction of private military contractors as legitimate actors of foreign policy. Despite this assertion made by scholars, private military contractors are an under studied political actor. This paper traces the historical, economic, and legal legacy of private military contractors in American history.

The Effects Of Music Instruction On Phonological Awareness In Children With Hearing Impairment, Chelsea Fitch

Masters Theses

Phonological awareness skills are essential for reading development. Children with hearing loss lack access to essential auditory information that allows development of phonological awareness (Dillon, John, & Pisoni, 2011). Music instruction is becoming a popular approach to teach reading for typically developing children, and studies have supported beneficial effects from this treatment methodology. However, there is limited research regarding the use of music to teach phonological awareness and reading skills to children with hearing impairment (Gromko, 2005).

The effectiveness of a music program on increasing phonological awareness skills in children who are deaf or hard-of-hearing was evaluated in this study. …

Assessment Of Range, Habitat Use, And Diel Movement Of Flathead Catfish (Pylodictis Olivaris) In The Wabash River Using Ultrasonic Telemetry, Sarah Mary Huck

Masters Theses

Flathead Catfish (Pylodictis olivaris) are one of the most targeted species for recreational and commercial fishing within the Mississippi River Basin. With heavy harvest pressure placed on many populations, proper management is crucial; however, the species range, habitat requirements, and diel movement patterns have rarely been investigated in free flowing rivers. Therefore, I used ultrasonic telemetry with active tracking to monitor movement and habitat use of 44 Flathead Catfish from August 2012 to December 2013 in the lower 280 km of the Wabash River. This system is ideal to evaluate broad and fine scale movement of Flathead Catfish …

Morphological And Ecological Investigations Of Species Of Bulrush (Scirpus) In Illinois, Julian G. Moore

Masters Theses

Two closely related species of bulrush, Scirpus atrovirens (Green bulrush) and Scirpus georgianus (Georgia bulrush), are widely distributed in Illinois. They are difficult to separate in the field, but readily distinguishable under magnification in the lab. These two species have been found in moist meadows, shallow marshes, edges of wet forests, and ditches. The objective of this study was to evaluate the morphological and ecological distinctness of the species with the aim toward discovering and describing other features to distinguish them reliably. Eighty plants of Scirpus atrovirens and 80 of Scirpus georgianus were examined. Fifty S. atrovirens and 50 S. …

Community College To A Four-Year Institution: Transition For Underrepresented Students, Sarah Adams

Masters Theses

Many four-year public institutions are experiencing increasing enrollment of students transferring from community colleges. For this qualitative assessment, six underrepresented students who transferred from a two-year community college to a four-year public institution were interviewed to examine both support and risk factors that underrepresented students experienced during and after the transition process. Findings showed that underrepresented students' common influential factors were finances, location, family/parental support, motivation and preparedness. The data revealed that underrepresented students experienced support from family, friends, TRIO, faculty and counselors while transitioning from community college. Risk factors that were revealed for underrepresented students at community college and …

The Path Into Student Affairs: How Undergraduate Experiences Influence Students To Pursue A Career In Student Affairs, Bryce Jacob Reuer Gergely

Masters Theses

The career field of Student Affairs is one that most individuals know nothing about until coming to college when they have the chance to interact with professionals in the field. How exactly do individuals come to be professionals in student affairs? This study looks to answer that question through the examination of nine individuals in various stages of the process into Student Affairs, analyzing their experiences throughout their undergraduate career. Special focus is given to experiences during participants' undergraduate education, influences on their decision to pursue Student Affairs as a career, and how interactions with Student Affairs professionals played a …

Revitalizing Grammar Instruction For High School Juniors: Toward A Contextual, Student-Driven, And Minimalistic Method, Heather L. Lindenmeyer

Masters Theses

In this thesis, I explore best practices in grammar instruction for high school juniors. Practicing English teachers have been engaging in the great grammar debate for years, essentially arguing if and how grammar is best taught. Thoughts on teaching grammar greatly differ in the professional community, but most scholars call for a middle ground to be sought in the great grammar debate. In other words, very few scholars think traditional methods that isolate grammar instruction from the writing process are best, but even fewer scholars call for teachers to entirely rid their curriculum of all grammar instruction. I conclude that …

Emotional Intelligence, Coping Styles, And Psychopathology, Letizia Boin

Masters Theses

Despite its relatively recent origins, Emotional Intelligence (EI), which is the ability to perceive, understand, and manage one's emotions, has been shown to contribute to a variety of outcomes, including academic achievement and relationship satisfaction. Considerable support has been gathered to implicate EI in the development of mental illness such as depression and social anxiety. It has been theorized that a potential pathway in which EI affects mental health is by contributing to the development of coping styles. Stress and coping literature reports enough empirical evidence to suggest that broadly speaking, problem-focused coping is 'adaptive' while avoidant coping is 'maladaptive.' …

Increasing Cooking And Nutritional Knowledge Of Food Pantry Clients Via Cookbook Intervention, Joshua Kleczynski

Masters Theses

This study was designed to assess eating habits, cooking habits, and nutritional knowledge of food pantry clients. As a whole, the average American consumes a less-than-optimal intake of nutrients. This, combined with the elevated national food insecurity rate of 14.5%, produces an advantageous situation to educate food pantry clients about healthy lifestyle practice through cooking. This study utilized a quasi-experimental design including a pre-assessment, intervention, post-assessment design. Forty-nine participants were included in study, and either received a cookbook (intervention group) or were a control subject and only completed surveys. Results revealed that the cookbook intervention did not elicit any behavior …

Exploratory Factor Analysis Of Body Dysmorphic Disorder Symptom Clusters, Rachel A. Maxwell

Masters Theses

Body dysmorphic disorder (BDD) is a distressing condition that involves a preoccupation with a perceived defect(s) in appearance. Despite the importance of early identification, it is often misdiagnosed. The literature suggests that issues with diagnosis may be because BDD is typically defined by the single symptom of dysmorphic concern (i.e., over concern with an imagined or slight defect in physical appearance). Dysmorphic concern is insufficient to fully characterize the disturbance. This study used exploratory factor analysis to identify symptom clusters from four well-known BDD measures completed by 457 undergraduate students. The extracted content suggested the following symptoms: (a) Dysmorphic Concern, …

The Perceived Benefits Of Participation In Living And Learning Communities: The Student Perspective, Sally Adams

Masters Theses

Students' experiences outside the classroom are important to their overall growth and development. Living learning communities (LLC) play a big role in helping to support these areas of growth. Students residing in an LLC are aware of the benefits of the LLC experience and can articulate how their residential environment can help them develop. Non-LLC members find it difficult to define the LLC experience and are not receiving the same benefits. Institutions and residence life often struggle in evaluating and assessing these communities because of the lack of direction and outcomes not clearly being stated. If institutions work to clearly …

Fear Of Negative And Positive Evaluation Across Social Evaluative Situations, Jarvis Howe

Masters Theses

Fear of negative and fear of positive evaluation are both important in understanding social evaluative anxiety. Fear of negative evaluation has been linked with social anxiety, public speaking anxiety, and test anxiety; whereas fear of positive evaluation has only been linked with social anxiety. This paper reviews the literature on fear of negative and positive evaluation in relation to each of the social evaluative situations and then presents the findings of a study that will attempt to differentiate the three types of social evaluative situations. Fear of negative evaluation was correlated with each of the three social evaluative situations; whereas …

Idiomatic Horn Writing: The Formal And Historical Contexts Of Four Horn Pieces, Elizabeth A. Danner

Masters Theses

As performers on the modern horn, we are presented with literature that was written for an instrument that differs from the one we use today. The fact that much of our solo literature was written for the natural horn does not invalidate our performances of it on the modern double horn. However, in order to present the music correctly, we must be aware of the development of the horn and historical context. In this document, I explore four pieces from different points in horn history. I assert the reasons each composer wrote the way he did by considering the physical …

Foreign Direct Investment Led Growth And Its Determinants In Sub-Saharan African Countries, Tewodros Zerihun Demelew

Masters Theses

Despite FDI's growth in Sub-Saharan African (SSA) countries, the evidence from earlier studies on FDI led economic growth and key determinants of FDI in SSA countries have been inconclusive. This paper provides up-to-date evidence on the question: does FDI lead to economic growth? And if so, what are the key determinants of FDI growth in SSA countries? In this study we use three estimation approaches, OLS with robust standard errors (robust regression), multi-level random-effects regression, and fixed-effects regression. The multi-level and fixed-effects regression are aimed to help us control for within-country and between-country effects. Based on a panel dataset for …

The Effects Of Existential Salience On State Anxiety, Joseph Morger

Masters Theses

Existential anxiety is theorized to result from one's knowledge of human existence. Four givens of life have been identified that result in existential anxiety: death, freedom, isolation, and meaninglessness (Yalom, 1980). Terror management theory purposes the knowledge of one's own death to be a great source of distress. The theory posits that to cope with these distressing thoughts, one is motivated to adhere to a cultural worldview. Adhering to a cultural worldview allows one to view the world as a structured place, in addition to raising one's self-esteem. Terror management research has shown that making mortality salient results in harsher …

Incremental Validity Of The Learning Behavior Scale In Special Education Evaluation, Margaret Lakebrink

Masters Theses

The Learning Behavior Scale (LBS) was developed as a teacher rating scale to assess students' learning behaviors hypothesized to affect academic achievement. Research utilizing the LBS has primarily stemmed from the standardization sample. The present study attempted to examine the incremental validity of adding the LBS to standardized intelligence test scores in order to predict standardized academic achievement in students participating in initial evaluations for determining disability and eligibility for special education services. Due to difficulty obtaining a sufficient sample, reevaluation cases were also obtained in the sample of first to eighth grade students (N=40) in the study. Results provided …

The Role Of Landmarks In Territory Maintenance By The Black Saddlebags Dragonfly, Tramea Lacerata, Jeffrey Lojewski

Masters Theses

Territoriality can reduce competition for resources, but territorial defense can be costly. Therefore any behavior that reduces territorial costs may increase the net benefit of territoriality. Some species will align their territory boundaries with conspicuous landmarks that may serve to reduce defense costs. Dragonflies, including black saddlebags (Tramea lacerata), defend territories at breeding sites, keeping rival males away to allow themselves access to females. We used three treatments to investigate whether T. lacerata used landmarks: constraining landmarks (an object that provided a physical barrier to flight), non-constraining landmarks (an object of the same dimensions and construction that did …

Effects Of Instream Habitat Restoration On Macroinvertebrate And Fish Communities In A Small Midwestern Stream, Manisha Pant

Masters Theses

Although millions of dollars are spent annually on stream habitat restoration, the biological responses to these restorations are rarely monitored. I assessed the impact of habitat enhancement on fish and macroinvertebrate abundance and diversity in a small Midwestern stream. Fish and macroinvertebrate communities were sampled annually in two restored and two unrestored sites beginning two years before and continuing four years after restoration. Habitat heterogeneity increased in the restored sites following the restoration, but there were no significant changes in most macroinvertebrate and fish community indices. Macroinvertebrate composition was significantly different between spring and fall, but in general, assemblages within …

The Experiences Of Community College Student Athletes, Holly Nichols

Masters Theses

Due to the scarce amount of research and prior literature regarding community college student athletes, the experiences regarding this group's athletics, academics, and social realms was investigated. This unique group is constantly forced to balance the time demands of academics and athletics, among other areas, at a level much more different than Division I student athletes. The results of the present study indicated that although community college student athletes may not compete at the same level as student athletes at the Division I level, the time demands, levels of support received, and academic behaviors are all similar in many ways. …
