Mdma And Learning: Effects Of Acute And Neurotoxic Exposure, Thomas P. Byrne

Dissertations

In two experiments, the effects of MDMA were examined on the acquisition of lever-press responding by rats exposed to procedures in which water delivery was delayed by 0, 10, or 20 seconds. In the first experiment, naive, water-deprived rats received an intraperitoneal injection of MDMA (0, 1.0, 3.2, or 5.6 mg/kg) prior to one experimental session. Response acquisition was observed under all conditions at all drug doses. MDMA increased both response rates and reinforcers earned in a dose-dependent fashion, but only when reinforcement was immediate. Under conditions of delay, MDMA had no effect on the number of lever presses emitted …

A Computer/Tutorial System Compared With A Workbook/Tutorial System For Presenting Instructional Material To At-Risk Elementary School Students, Vincent O. Hodge

Dissertations

Two different ways of presenting instructional material and reacting to students’ responses were compared. One, taking advantage of several features of multimedia instruction involved a desktop computer and various computer-presented consequences of correct and incorrect responses (largely chosen by the student). The other consisted in presenting the same instructional materials (the SRA primary curriculum) in a workbook form with tutors' comments and praise as the main form of response consequence. The two methods were compared with respect to various measures of student and system performance, including student accuracy (percent correct responses), types of errors, amount of correct response repetition (over-responding), …

The Lost Treasure Of Valencia: Fugitive Muslims From The Kingdom Of Valencia 1290-1410, Michael A. Ryan

Masters Theses

The fourteenth century, an epoch infamous for war, disease, famine, and devastation across the whole of Europe, also saw an increase in the number of fugitive Muslims from the Christian kingdom of Valencia. Due to the reconquest of Valencia in the thirteenth century, an immense Muslim populace found itself subject to a dominant Christian minority. These Muslims had been either enslaved outright for resisting the Christian domination, or had been placed into a semi-free status. The members of this latter group were known as the Mudejars, and like the Muslim slaves, fled when their social and political standings were in …

Perceptions Of Corporate Crime: Assessing The Seriousness, Dale J. Ardovini-Brooker

Masters Theses

Many studies have been done concerning the seriousness of traditional street crime. There is a need in the field of criminology to expand our knowledge about how serious corporate crimes are. A key feature of seriousness is how researchers measure it. Using a survey, I analyzed people's perceptions of corporate crime. I had the respondents indicate the seriousness of the crime and harm by using a Likert Scale as well as identifying the appropriate sanction/sentence for the company convicted of the crime. This proved useful in attempting to identify how seriousness is measured by the sanctions/sentences imposed by the respondents. …

Delectatio Et Utilitas In Hrotsvit Of Gandersheim's Resuscitatio Drusianae Et Calimachi, Mary Maxine Browne

Masters Theses

Hrotsvit of Gandersheim (935-1002 A.D.) wrote her play, Resuscitatio Drusianae et Calimachi, as the other five plays which Hrotsvit composed, as an adaptation of a hagiography from the apocryphal Acta Johannis. Written in the spirit of the tenth-century didactic esthetic delectatio et utilitas, Hrotsvit adapted the narrative of the legend to the Terentian comedic form, that she might instruct her monastic audience according to the delectatio et utilitas esthetic.

This discussion focuses on the sources and backgrounds of Hrotsvit's play, followed by Hrotsvit' s adaptive treatment of the characters in Resuscitatio Drusianae et Calimachi with a …

A Comparison Of Reported Teacher Selection Practices Of Elementary Principals In Michigan To Recommended Selection Methods, John E. Jarpe

Dissertations

Teacher selection is a complex, critical school personnel function. School leaders in Michigan’s districts will be hiring more teachers as projected enrollment increases and pending teacher retirements combine to open teaching positions. This study examined the effectiveness of teacher selection practices as they compared to selection methods described in administrative textbooks, journal articles, and research studies.

Thirty-six Michigan elementary principals reported their school building and district selection procedures. Qualitative analysis focused on their transcribed responses to interview questions about the aspects of teacher selection. The principals represented public schools that combined varying grade levels of kindergarten through sixth grade.

The Influence Of Promise Keepers On Fathers’ Involvement With Their Children, Michael J. Walcheski

Dissertations

This study explores the influence of Promise Keepers (PK) on fathers’ involvement with their children. The large numbers o f men involved with PK and the anecdotal success of fathers and their families have created considerable dialogue in the popular press. However, there have been no empirical studies to date that contribute data about the influence of PK on father involvement.

The conceptual framework informing this study combined father involvement and postmodern feminist perspectives. A father involvement perspective emphasizes fathers’ presence, their capability and strengths, the moral dimension to fathers’ responsibility for their children, and factors that establish responsible fathering. …

Glucose Mediated Effects On Glucose-6-Phosphate Dehydrogenase Expression, Daryl Arkwright

Masters Theses

Circulating high glucose levels are believed to cause oxidative stress which is implicated in a number of pathological conditions such as cancer, aging, and diabetes. Oxidative stress regulates the expression of glucose-6-phosphate dehydrogenase (G6PDH), the key enzyme in the pentose phosphate pathway which provides reducing equivalents in the form of NADPH. These reducing equivalents are also required by fatty acid synthase (FAS), the enzyme which catalyzes fatty acid biosynthesis. We examined whether glucose, a known inducer of oxidative stress, could regulate either G6PDH or FAS activity in primary rat hepatocytes. We tested the effects of glucose alone or in combination …

Mechanism By Which Insulin And Its Mimetics, Selenate And Vanadate, Regulate Glucose-6-Phosphate Dehydrogenase Gene Expression, Sanjay M. Jivraj

Masters Theses

Glucose-6-phosphate dehydrogenase (G6PDH) is a key enzyme of the pentose phosphate pathway. It controls the carbon flow through this pathway, producing reducing equivalents in the form of NADPH to meet the cellular need for reductive biosynthesis and the maintenance of the cellular redox state. Hepatic expression of G6PDH has been shown to be regulated by hormones, nutrients and some growth factors, however the mechanism by which these factors regulate G6PDH gene expression has not been characterized. Here we investigate the mechanism by which insulin and its mimetics, selenate and vanadate, regulate G6PDH gene expression.

Insulin exerts its tissue specific affect …

Stage-Dependent Expression Of Target-Derived Influences Stimulates Axon Outgrowth In Hirudo Medicinalis, Tina M. Harik

Masters Theses

Our lab has been investigating the development of neuronal phenotype and circuitry in Hirudo medicinalis. Early in embryogenesis the heart excitor (HE) motor neuron selectively extends multiple arbors into the body wall prior to heart tube (HT) formation. HE contact with HT primordium at later stages of development results in remodeling such that arbors are elaborated on the HT, while those in the body wall are retracted. HT-derived cues are necessary for HE remodeling (Jellies, 1995. Am. Zool. 35:529; Jellies and Kopp, 1995. Invert. Neurosci. 1:145). HT and body wall explants were co-cultured to investigate the possible influences of …

Poor Children "Know Their Place": Perceptions Of Poverty, Class, And Public Messages, Susan Weinger

The Journal of Sociology & Social Welfare

This qualitative study hears and clarifies some of the voices of children concerning how they feel their lives are circumscribed by living in poverty, by public messages about the poor, and by their views of their socioeconomic status. Twenty-four children between the ages of 5-12 years were interviewed using snapshots of different economic level homes in order to capture their uncensored responses. Findings reveal that the children view poverty as a deprivation, perceive societal messages as disparaging of the poor, and have some difficulty holding on to positive views of themselves. These children's thoughts about the realities of their lives …

Rethinking Selectivism And Selectivity By Means Test, Chack-Kie Wong

The Journal of Sociology & Social Welfare

This article casts doubt on conventional thinking about selectivism and its narrow focus on the selective process. It is argued that selectivity is fairly neutral; even universal access to welfare is not free from the attachment of social stigma to welfare beneficiaries. The increase in benefits standards, another common strategy advocated by egalitarians, may not produce the desirable de-stigmatized effect for beneficiaries. Our status ranking conception of social relations, reflecting the operation of the success ideology, holds the key to the transfer of social stigma in the social exchange of welfare benefits. In this regard, we need .to study the …

Integrating Technology And Foreign Language Learning, Margaret Bullard

Honors Theses

We are currently experiencing what some refer to as an "information revolution." This began with the appearance of writing systems, the invention of the printing press, the telephone, the mass production of audio and video tape recorders, the photocopy machine, the microcomputer, and now the Internet and Worldwide Web (WWW). The growth rate of the WWW has been incredible since the first version was made available in 1993. Aside from the large number of web sites that have been created, the U.S. Department of Education claims that 20,000 educational software titles have been developed and more than one million students …

The Effects Of Rose Bengal Application On The Production Of Salicylic Acid In Nahg Tobacco Plants, Nicole Christine Ott

Honors Theses

Plants have the ability to develop resistance to a wide range of pathogens following exposure to a single bacterium, fungus, or virus. This resistance occurs in all tissues, not only those that were previously infected. This mechanisms is termed systemic acquired resistance (SAR). The phenolic compound salicylic acid (SA) has been linked to SAR in tobacco, arabidopsis, and cucumber plants. Oxidative stress also causes SA production, which leads to SAR. An engineered tobacco plant (nahG) that does not have the ability to accumulate SA has been used as a research tool in investigations concerning SA activity. Rose Bengal …

Effects Of Zinc On Glucose-6-Phosphate Dehydrogenase In Buffalo Rat Liver Cells, Bryan G. Sauer

Honors Theses

In recent years, interest has surfaced in the use of insulin-mimicking agents for diabetic therapies. Zinc has been shown to have insulin-like effects in vivo and in vitro but has never been studied for its ability to mimic insulin in the regulation of carbohydrate and fatty acid metabolism. Therefore, the author studied the effects of zinc on glucose-6-phosphate dehydrogenase (G6PDH), an enzyme stimulated by insulin that is imperative in both carbohydrate and fatty acid metabolism. Because G6PDH is highly regulated in liver cells, a stable rat liver cell line, Buffalo Rat Liver (BRL), was used. Endogenous G6PDH activity and G6PDH …

Registration Laws And Their Impact On Voter Retention, Tom Lenard

Honors Theses

The literature on voting participation suggests a number of factors that should affect voter turnout differences including the legal incentives or hindrances acting directly on individual citizens. In this study I examine registration laws and how they may play a role in the stability over voter turnout between presidential and midterm elections. Specifically, this research concentrates on classifying each individual state into groups with easier and those with more strict registration requirements. With this done, I compared the voter turnout for the 1990-1996 elections between the two groups. Also, I looked at the drop-off rates in percentage of turnout for …

The Art Of The Novel: How Kundera Helps Us Read The Unbearable Lightness Of Being, Matt Plavnick

Honors Theses

In all of Kundera's writing there is the search, the yearning, to understand more of the world around us~specifically around Kundera. His fiction deals both with the lives of people caught up in this world, some happily, some miserably, each undeniably held by human constraints, and also with how these people are affected by their natural constraints. His critical writing offers further examination and theory about these constraints: what they are, specifically, how they work, and how they affect people. With this comes a detailed assessment of our epoch, which he calls "The Modern Era," and the phenomena that characterize …

Eliminating Coating Flakes With Ultrasound, Ryan Zarbaugh

Paper Engineering Senior Theses

As paper mills took to reuse as much internal waste as possible, problems in the system can be introduced. The buildup of deposits or fluctuations of chemicals can occur when more broke is introduced. In mills that add a layer of coating to the paper problems associated with the coating can be introduced. At Champion International in Hamilton, Ohio, a heavy layer of coating added to the sheet introduces the problem of coating flakes to the system.

It was hypothesized that the use of the ultrasonic cavitation mechanism should be able to break the flakes apart and reduce the overall …
