Assessment Of The Immune Response To Posthodiplostomum Minimum Infection In Bluegills, Olamide S. Olayinka

Masters Theses

Bluegills (Lepomis macrochirus) are common intermediate hosts for white grub (Posthodiplostomum minimum). They tolerate heavy infections with minimal effect on condition and continue to accumulate metacercariae as they age. This suggests that any immune response to this parasite might not be effective. This study was conducted to better understand the immune mechanisms underlying P. minimum infection in bluegills.

Infected organs (liver, kidney, and heart) were examined histologically, and serum from infected fish was tested for antibodies to white grub. Juvenile flukes were recovered from isolated metacercarial cysts. Polyclonal antibodies were produced in mice against white grub …

Effects Of Exposure To World Folk Music On Preference For Unfamiliar Music In Elementary General Music, Jessica Doty

Masters Theses

The purpose of this action research study was to discover whether students' experience with folk music from other countries influenced their preference for other unfamiliar music genres. Third grade students were assigned to one of two groups. Students in Group A participated in four weeks of lessons centering on folk music from Ghana, Japan, Israel, and Mexico. Students in Group B participated in four weeks of lessons centering solely on American folk music. Students in both groups answered questions on a listening survey which gauged their preference for unfamiliar pieces of music. The listening survey was given to students before …

Monitoring Temporal Trends In Catostomidae Larvae In Large Sized River Tributaries, Kellie Nicole Hanser

Masters Theses

Large river ecosystems can support a complex network of tributaries that provide optimal habitat for fish reproduction. Anthropogenic alteration of rivers and tributaries has been shown to have adverse effects on river fish communities, but few studies have focused on the effects river regulation may have on the reproduction of native suckers (Family Catostomidae). In this study, I evaluated differences in biotic and abiotic factors associated with catostomid reproduction between tributaries of an altered and free-flowing river. I conducted ichthyoplankton sampling using drift nets and larval push nets in tributaries of the Illinois River, which is regulated for navigation, and …

A Pilot Study On The Effects Of Comparative Feedback And Performance On Students’ Self-Efficacy And Self-Esteem, Claire Schneider

Masters Theses

This study compared the effects that academic performance and comparative feedback have on student self-efficacy and self-esteem. Through mobile device polling, participants were able to complete in-class multiple-choice conceptual questions. Participants included 35 college students in two psychology classes assigned to a control and experimental group. For the control group, the class was shown a graph of student responses following each question and the experimental group was not shown how their peers performed. This allowed individuals in the control group to compare their own scores to peer scores while the experimental condition was not provided the comparative feedback. Data were …

Investigating The Economic Impacts Of Globalization On Employment Generation In Africa: Case Study Of The Ecowas, William Dickson Amenyo

Masters Theses

A review of the ongoing debate on the economic impacts of globalization on employment in developing economies shows that the predictions of most trade theories that, an increase in globalization would result in more employment in labor abundant countries has not always proven to be true. This study actually examines the employment impact of economic globalization to recipient economies – ECOWAS member states. The analysis has employed a balanced panel dataset of 13 ECOWAS member nations over the period 1990 – 2017. Based on the Fixed Effects estimation approach, the empirical analysis reveals that over the full sample, economic globalization …

Identification And Analysis Of Genes With Differential And Tissue-Specific Expression In Poplars, Bailey Mitchell

Masters Theses

Poplars have become one of the most frequently studied plant species for their applications in biotechnology, commercial benefits, and ecological importance. Microarray analysis is commonly used to analyze differential gene expression in many organisms. Investigations have examined differential gene expression and performed functional analyses on a single tissue or organ within poplar trees or a closely related set of tissues and organs, but usually do not broadly analyze gene expression across a large number of tissues and organs in poplar. This thesis work aims to generate data on the most differentially expressed genes for the major groups of tissues and …

How Thick Is The Stained-Glass Ceiling?: An Exploration Of Heteronormativity In Religious Circles, Hannah Rae Smothers

Masters Theses

The 2012 National Congregations Study found that only 11.4% of the total clergy in the United States were women (ARDA 2012). As the congregation size grows, that number declines further, with data indicating only 3.4% of congregations with 1,000 or more members have a female leader. The number of women religious leaders increased by less than one percent between 1998 and 2012. These statistics work well to outline a phenomenon for female religious leaders, their inability to break the stained-glass ceiling. Many religious groups in the United States allow women to become ordained leaders. However, some of the largest religious …

Relationship Between One’S Motive For Curiosity And Meaning In Life, Charles Reither

Masters Theses

Meaning in life as a psychological construct has many demonstrated benefits for psychological well-being and optimal functioning (Steger, 2013), and the treatment of clinical populations (Thir & Batthyány, 2016). This study investigated in greater detail than is currently available in the psychological literature how meaning in life is related to curiosity. Meaning in life was explored using top-down (the presence of and the search for meaning) and bottom-up (the specific sources of meaning) approaches. Curiosity was examined in its two motivation-based forms: curiosity motivated by the anticipation and enjoyment of discovery (an appetitive interest-type of curiosity) and curiosity motivated by …

The Living Mission: Mission Statements Evidenced In The Student Experience, Darek D. Hollis

Masters Theses

Mission statements are thought to be documents that hold the core purposes of an organization. While several studies have examined the various aspects of higher education mission statements, few have explored how the themes within mission statements are transferred to those the institutions is serves, it’s students. This qualitative studied used semi-structured interviews with graduating senior students at a mid-sized, Midwest institution to examine whether or not the missional themes were evident in and valuable to the students’ experience. The result of the study found that the missional themes were in general present and valuable in the students’ experience. The …

Bigheaded Carp Spatial Reproductive Dynamics And Population Genetics In Large River Tributaries, Samuel J. Schaick

Masters Theses

Fisheries managers are devoting considerable effort, time, and funding towards limiting the spread of invasive Bighead and Silver (bigheaded) Carp. A better understanding of factors that influence spatial patterns of bigheaded carp reproduction can help fisheries managers prevent their spread. To examine factors that influence spatial patterns of reproduction, we sampled ichthyoplankton using drift nets and larval push nets in three tributaries of the Illinois and Wabash Rivers March-September 2016-2018. We compared relative abundances of bigheaded carp eggs and larvae among tributaries using catch per unit effort (CPUE). Abiotic data were analyzed from individual study tributaries and pooled among tributaries …

A Cloning Strategy For Expression Of Fungal Hemicellulases In Plant Systems, Amer Alrudayan

Masters Theses

Lignocellulosic biomass is notoriously difficult to deconstruct into lignin, hemicellulose, and cellulose fractions without the use of biochemical, chemical, and/or mechanical pretreatments. These pretreatment strategies add operational cost and in some cases produce hazardous waste that poses health and safety risks. Direct biological pretreatment from biomass-degrading bacteria and fungi may significantly reduce the costs and risks associated with these traditional strategies due to the innate ability of these organisms to modify plant cell walls. An additional measure that could further reduce the expenses associated with lignocellulosic biomass fractionation is genetic modification of the lignocellulosic feedstocks, which can be accomplished by …

The Transcriptome Response Of The White-Rot Fungus Trametes Versicolor To Wild-Type And Lignin-Modified Hybrid Poplar, Anbarah Alzabaidi

Masters Theses

Plant biomass is a renewable and sustainable feedstock for biofuel production that can reduce societal dependence on fossil fuels. However, the production of liquid biofuels from the non-starch (i.e. lignocellulosic) material through fermentation technology is limited due to the complexity of the cell wall structure. This necessitates the use of chemical, thermal, and/or mechanical pretreatment technologies, which adds significant capital, operational, and environmental costs. Biological pretreatment strategies have the potential to mitigate these expenses by harnessing the innate ability of specialized bacteria and fungi to deconstruct lignocellulose. White-rot fungi (e.g. Trametes versicolor) have been shown to be …

Effects Of Insect Opportunists On A Four-Level Trophobiotic System Involving Nectar-Producing Galls Of The Cynipid Wasp Disholcaspis Quercusmamma (Hymenoptera: Cynipidae), Stephanie L. Smith

Masters Theses

The induction of plant galls is considered an adaptive life history trait found in many insect groups. The formation of galls provides several advantages to the gall maker, such as enhanced nutrition, favorable microclimate, and protection from natural enemies, including parasitoids, inquilines, and predators. Order Hymenoptera has many gall-making species, belonging to the gall wasp family Cynipidae. As an extended phenotype of the gall makers, some galls exhibit very sophisticated adaptive mechanisms involving multilevel species interactions. In particular, the oak galls of the Cynipid species Disholcaspis quercusmamma, found in much of Illinois, produce a palatable, sugary nectar-like secretion, attracting …

Construct Validity Of The Teate Depression Inventory: Convergent And Discriminant Validity And Equivalence For Black/African American And White/Caucasian Samples, Dylin Coons

Masters Theses

The purpose of this study was to replicate the construct validity of a new measure of depression, the Teate Depression Inventory (TDI; Balsamo & Saggino, 2013), with the primary focus on Black/African American participants. Research has purported that Black/African Americans experience inequality in obtaining mental health care for internalizing disorders. This may partially be caused by errors in diagnosing these individuals with symptoms. Correctly diagnosing internalizing disorders is a critical step in obtaining appropriate treatment. More research on depression and anxiety is needed to enhance mental health practices by addressing the need for professionals to be culturally competent and conscious …

Teachers used an average of 1.7 total diverse praise categories per observation. Both middle and high school teachers used more general diverse praise categories compared to behavior-specific diverse praise categories. The …

An Intricate Ensemble : The Art-Science Of An Ecological Imaginary For The Anthropocene Epoch, Alyce Santoro

Masters Theses

The contradictions inherent in European Enlightenment-based “logics” that externalize humans from “nature” were a concern for the Romantic Naturalists, Dadaists, and Surrealists. More recently, some in the environmental humanities and socio-ecologically-concerned arts and sciences have also posed challenges to anthropocentric, hierarchical, positivist modes of thought. I suggest that by engaging the ludic, imaginative, and collaborative while bearing the empirical in mind, dualisms (such as objective and subjective, individual and collective) dissipate, and existence as a dialectical state of intricate ensemble can be revealed. In light of catastrophic disruption to Earth’s life-sustaining processes by exploitative forms of human activity, I argue …

Is There A Need For Restoration Of Justice In Democratic India?, Abraham Sekhar

Masters Theses

Justice means giving all persons their due. Justice is the quality of being fair and reasonable. India has the largest democracy in the world. It has become noticed globally by most other countries, on the one hand, for its significant economic growth during the past two decades; and on the other hand, for its domestic unrest among people of different religions and castes. Under the rule of the present political party, India’s economic growth has experienced a sudden decline during the past three years. This drew my attention to find out the reasons for such a decline. A literature survey, …

Creating Alabama Music Heritage And Theory: Equipping Students With State Pride Through Effective Curriculum, Julianne Rae Mattox

Masters Theses

Across general music curricula, there is always a concern for student interest. For elementary age students, music is viewed as magical and fun. It seems that as students age, if they are not in band, music begins to lose some of its magic. With any class, student interest and involvement is key for the academic success of the curriculum. If students have to take a class that they do not want to take, they automatically lose interest. It is important for teachers to present their curriculum to students in a way that grabs their attention and allows them to enjoy …

Supporting Black Mothers At The Transition: A Collaborative Design Prenatal Coparenting Program, Jordan Ebanaya

Masters Theses

Despite having the highest infant mortality rate of similarly developed nations, infant mortality rates have trended downward in the United States, however, the infant mortality disparity between Black and White infants persists. The causes of the disparity have been traced to social considerations of the mother especially while pregnant. These social situations include racism and discrimination, marital status of the mother, social support and pregnancy intentions, pointing to one commonality: stress. Using Boss and colleagues 2017 Conceptual Model of Family Stress, this study proposes a solution to address some of the social support, or resources, available to the expectant mother; …
