Crops And Controversy: Industry’S Role In The Gmo Debate, Carina Wallack

Honors Theses

The use of genetically modified crops (also called GM crops, genetically modified organisms, or GMOs for short) has become a highly contested issue. New genetic modification technologies offer a variety of advantages for improving agricultural efficiency. However, some scientists argue that the safety testing conducted thus far does not provide enough information and worry about possible health and ecological risks. Private industry sponsors a great deal of research on genetically modified crops. As the international controversy regarding the use of GMOs has unfolded, the very companies responsible for commercializing genetically modified crops have gained substantial influence in the resulting scientific …

Evaluation Of Ecto-Mycorrhizae As A Determinant Of Chestnut Growth And Stress Response, Pabitra Aryal

Masters Theses

Although agriculture focuses on row crops throughout much of the Midwest, chestnut (Castanea spp.) appears to be an agroforestry crop well suited as a sustainable alternative to row crops in areas prone to erosion. As ectomycorrhizal (ECM) colonization is often crucial for tree establishment and production, I addressed the importance of ECM colonization on chestnut performance by assessing 1) natural ECM colonization in an established chestnut orchard and 2) the effect of experimental ECM inoculation on seedling establishment and drought response in a greenhouse. In the established orchard, I selected 50 Chinese-American hybrid chestnuts (C. mollisima x C. dentata …

The Effects Of Religious And Body-Related Affirmations On Disordered Eating Attitudes And Body Dissatisfaction, Cassandra A. Vogt

Masters Theses

The relationship between disordered eating, body dissatisfaction, and religion is complex. Previous research demonstrated that religious body affirmations are beneficial in reducing body dissatisfaction among undergraduate females. Because previous research used affirmations which were simultaneously religious in nature and related to the body, it is difficult to determine if the religiousness of the affirmation is the beneficial characteristic. The current study investigated which type of affirmation had the strongest effect on disordered eating attitudes and body dissatisfaction. More specifically, the five experimental conditions included: religious body affirmations, religious non-body affirmations, non-religious body affirmations, non-religious non-body affirmations, and neutral control statements. …

The Financial Burdens Associated With Managing Pku Dietary Needs As An Adult, Melissa C. Bernzen

Masters Theses

This study was designed to identify the financial burdens associated with purchasing medical foods and the impact this has on the dietary management of adults with PKU. PKU is a genetic disorder in which the body cannot metabolize the amino acid, phenylalanine, which occurs in all foods with protein. Dietary treatment of foods low in protein along with medical supplementation is required for the treatment of PKU. If PKU is left untreated this can lead to severe neurological damage. Medical guidelines indicate that dietary treatment is needed for the duration of one's life, but the medical foods needed are expensive …

The Effects Of Limb Dominance On Cross-Education In A Four Week Resistance Training Program, Caitlin Wend

Masters Theses

Cross-education is known as the phenomenon of strength transfer from the trained side of the body to the untrained side of the body by unilateral resistance training. Research has shown that limb dominance has an effect on the amount of strength that is gained on the untrained side. Studies have found that there is a greater cross over effect in strength from the dominant side of the body to the non-dominant side of the body than vice versa. The present study examined this effect by taking 12 college females and splitting them into three groups: dominant training, non-dominant training, and …

Morphology And Variation In The Gargle Call In A Chickadee Hybrid Zone In Central Illinois, Shannon Marie Regan

Masters Theses

Black-capped (Poecile atricapillus) and Carolina Chickadees (P. carolinensis) have distributions that span the northern and eastern portions of the United States. The areas where these distributions meet are called contact zones and extend from Kansas to New Jersey. Contact zones often have a narrow range of hybridization and usually within these zones of hybridization we will see a mixture of genetic, morphological, and cultural traits. One focus of this project was to compare morphology and genetics of chickadees within and near the largest Illinois contact zone, which has not been done previously. This contact zone was …

Development Of A High Throughput (Ht) Raman Spectroscopy Method For Rapid Screening Of Liquid Blood Plasma From Prostate Cancer Patients, Dinesh Medipally, Adrian Maguire, Jane Bryant, John Armstrong, Mary Dunne, Marie Finn, Fiona Lyng, Aidan Meade

Articles

Extensive research has been undertaken on the examination of tissue biopsies using vibrational spectroscopic techniques. However, fewer studies have focused on less invasive and commonly acquired blood samples. Recent studies have shown the ability of Raman and Fourier transform infrared (FTIR) spectroscopy to discriminate between non-cancer controls and cancer cases using blood serum or plasma. Even though many studies have proposed Raman spectroscopy as a potential diagnostic tool in various cancers, the Raman spectroscopic technique has not been introduced as a routine clinical technology. This is due to multiple drawbacks with the application of the technique, including sample preparation, the …

Aging Injunctions And The Legacy Of Institutional Reform Litigation, Jason Parkin

Elisabeth Haub School of Law Faculty Publications

Institutional reform litigation has been an enduring feature of the American legal system since the Supreme Court’s ruling in Brown v. Board of Education. The resulting injunctions have transformed countless bureaucracies notorious for resisting change, including public school systems, housing authorities, social services agencies, correctional facilities, and police departments. But these injunctions face an uncertain future. The Supreme Court has held that institutional reform injunctions must be easier to terminate than all other injunctions issued by the federal courts. Some institutional reform injunctions go unenforced or are forgotten entirely. Others expire due to sunset provisions. At the same time, doctrinal …

The purpose of this study was to examine whether parents' and teachers' perspectives regarding parental involvement and student achievement differed at the school. Epstein's theoretical framework was used as the basis for this quantitative study. …

The Use Of A Patient Mobility Sensor To Decrease Hospital-Acquired Pressure Ulcers, Monica Vassallo Shallow

Walden Dissertations and Doctoral Studies

Pressure ulcers are a serious health condition that have negative consequences for patients and organizations. The primary cause of pressure ulcers is intense and/or prolonged pressure or pressure in combination with shear that results in damage to the skin and underlying soft tissue. Early identification of patients at risk for pressure ulcers and 2-hour repositioning to off-load pressure are key components in reducing pressure ulcer development. Despite ongoing efforts to prevent pressure ulcers, the incidence and prevalence of hospital-acquired pressure ulcers (HAPUs) at the practicum site exceeded the benchmark for Magnet hospitals and the health system's goal of 1%. Patient …
