Do Artificial Riffles Enhance Nutrient Retention In Restored Streams?, Adam Thomas Hughes

Masters Theses

Kickapoo Creek, a tributary of the Embarrass River in Central Illinois, has undergone a stream restoration that included the construction of two artificial riffles. These structures were designed to slow flood waters, increase channel and substrate stability, and increase habitat heterogeneity in a stream impacted by erosion and sediment deposition. They may also provide stable substrates that affect the algal community, leading to shifts in algal community composition, increases in the biomass of primary producers, and subsequent increases in nutrient retention. I explored the effects of the restoration on instream nutrient retention by measuring and comparing phosphate uptake lengths, velocities, …

Habitat Associations Of Larval And Juvenile Fishes In A Large Unimpounded River, Sharon V. Rayford

Masters Theses

Larval and juvenile life stages of fish are numerically the dominant component of fish populations. These early life stages experience high levels of mortality due, in part, to anthropogenic disturbances, but little is known about which habitats they utilize in large-rivers, as they are often difficult to sample and identify. My study examined the larval and juvenile fish assemblages in different habitats within the lower 322 km of the Wabash River. Fish were sampled with a conical-cylindrical ichthyoplankton net (larvae) and a DC-electrified mini-Missouri trawl (juveniles) between May and October 2013. Larval fish were collected every two weeks from mid-May …

The Relationship Between Classroom Management, Coping Styles, And Stress, Shawna Hoots

Masters Theses

One of the major demands that contributes to the stress of teachers is how to manage students' problem behaviors in the classroom. However, coping strategies may buffer the effects that classroom management styles have on stress levels in teachers. The purpose of this study was to examine the relationship between classroom management styles and stress and how coping may moderate this relationship. Participants included 94 teachers from across northern and central Illinois. Indifferent classroom management style was associated with higher levels of stress, though no other significant correlations were found among stress and classroom management styles. Emotion-focused coping and problem-focused …

Personality Traits And Character Strengths As Predictors Of Well-Being, Carissa Johnsen

Masters Theses

The purpose of this study was to gain a better understanding of how character strengths (i.e., positive characteristics about a person that can be developed) can predict subjective well-being above and beyond personality. Although the relationship between personality and well-being is well-understood, there is little research done comparing personality and character strengths and how character strengths may provide added value in predicting subjective well-being. Thus, the present study sought to examine whether character strengths will predict subjective well-being above and beyond personality. Two-hundred and thirty seven participants responded to scales measuring each person's personality traits, character strengths, satisfaction with life, …

Exploration Of The Relationship Between Schizotypal Traits And Well-Being, James Ciulla

Masters Theses

The purpose of this study was to explore the construct of schizotypy and whether or not it may have benefits within different conceptions of psychological health, or well-being. Schizotypy is a construct that emerged around the turn of the 20th century. It had historically incorporated aspects later reclassified under other areas of dysfunction, or relegated to social value judgment, and is currently the cause of some debate in the field (Acar & Sen, 2013; Carson, 2011; Farias, Underwood & Claridge, 2013; Kendler, 1985; Tsakanikos & Claridge, 2005; Vollema & van den Bosch, 1995).

Substance Abuse In Older Adults: An Exploratory Study, Rachael Hawn

Masters Theses

The increasing number of older adults in the United States, due in part to the Baby Boomer generation, means that there is also an increase in the number of older adults dealing with substance abuse problems. The compounded effects of multiple legal medications with alcohol, illicit drugs, or abused prescription drugs on the withdrawal process are likely to make delineating between legitimate medication side effects and withdrawal symptoms incredibly difficult for medical professionals working with older adults. With the average older adult legally using 17 medications from nine different medical professionals, the physical effects of substance abuse might easily go …

Differences In Mental Health Treatment Recommendations For Older And Younger Adults, Michelle M. Smith

Masters Theses

Failure to meet geriatric mental health needs is increasingly problematic. Research indicates that the problem is not simply a matter of insufficient numbers of mental health practitioners (MHPs), but also ageist attitudes and lack of knowledge about and training with older adults. The current study reviews the literature regarding knowledge about older people, education and training that mental health professionals receive, and the attitudes that are held by mental health professionals. The study also assessed for differences in treatment recommendations that MHP made for older versus younger clients, investigated whether MHP knowledge about the mental health of older adults, attitudes …

Aspects Of The Trophic Ecology Of An Invertivorous Snake Community, Meagan Amanda Thomas

Masters Theses

Understanding the significance of trophic links has been of interest to ecologists for decades, likely because food web studies have the potential to reveal a considerable amount of information in the fields of ecosystem and community ecology. Despite the intrinsic benefits that come from elucidating food web structures, doing so is often problematic because of the complex and dynamic nature of ecological communities. The dietary ecology of small-bodied invertivorous snakes remains relatively understudied compared to other snake species. Many of these species are abundant throughout their range, making them ideal organisms for studying community-level questions. I employed a combination of …

The Effects Of 1, 3, & 7 Trisubstituted And 8-Cyclopentyl Alkylxanthines On Respiration In Newborn Rats, Nathan Creel Davidson

Masters Theses

Methylxanthines have been shown to be promising respiratory stimulants in newborns suffering from recurrent apnea. The respiratory stimulant effects of methylxanthines are most likely due to their antagonism of adenosine receptors. These drugs have been shown to stimulate respiration in newborn rats in doses in excess of 10 mg/kg body weight. Structure-activity studies have shown that methylxanthines not only differ in the antagonism of A₁ and A₂ adenosine receptors but also, as a consequence of their different chemical structures, differ in potency as respiratory stimulants. To assess this, two potent A₁ adenosine receptor antagonists, 8-cyclopentyl-1,3-dipropylxanthine (DPCPX) and …

Subjective Time And Mindfulness, Ian Lesueur

Masters Theses

The purpose of this study was to gain a better understanding of how time is subjectively experienced when one is being mindful or fully engaged in the present moment. Although attending to and being aware of the present moment is a defining feature of mindfulness (Brown & Ryan, 2003), there has been little research done concerning how time is experienced when being mindful. Thus, the present study examined the relationship between mindfulness and four different conceptions of the subjective experience of time: Time Perspective, Balanced Time Perspective, Temporal Focus, and Temporal Depth. One hundred and forty-two university students responded to …

Effects Of Dams On Fish And Macroinvertebrate Communities In The Vermilion River, Il, Ryan Patrick Hastings

Masters Theses

Dams are a main source of anthropogenic disturbances on river systems and can affect rivers in a variety of ways. Dams have the ability to change rivers from lotic to lentic habitats, affect sediment transportation, connectivity, water quality, linkages with wetlands and the quality of in-stream and riparian habitats. The Danville Dam was constructed in 1914 on the Vermilion River in Danville, Illinois and is becoming a safety hazard for human recreation on the Vermilion River, resulting in three deaths in the last 10 years. The Illinois Department of Natural Resources in conjunction with the city of Danville has proposed …

Reuniting Old Allies: A Case For Creative Composition, Stephen M. Jefferies

Masters Theses

Since the split between creative writing and composition that largely occurred in the late 1920s, the two departments have wrestled with boundaries that have defined and challenged both courses. Despite the occasionally contentious relationship between creative writing and composition/rhetoric scholars, the two disciplines have served as strong allies in the past. "Reuniting Old Allies" argues that returning to such an alliance could provide a fruitful, blended approach to writing.

This thesis traces the history of this schism from Aristotle to the modern English department, attempting to reconcile the two departments with a middle-ground approach called critical-creative composition that emphasizes the …
