Comparison of Risk Assessment-Predicted Ecologically Safe Concentrations of Azinphos-Methyl and Fenvalerate to Observed Effects on Estuarine Organisms in a South Carolina Tidal Stream Receiving Agricultural Runoff

Comparison of Risk Assessment-Predicted Ecologically Safe Concentrations of Azinphos-Methyl and Fenvalerate to Observed Effects on Estuarine Organisms in a South Carolina Tidal Stream Receiving Agricultural Runoff

Date: August 1997
Creator: Morton, Michael Gerard, 1957-
Description: A prospective ecological risk assessment method was developed evaluating the cumulative probabilistic impact of chemical stressors to aquatic organisms. This method was developed in response to the need to evaluate the magnitude, duration and episodic nature of chemical stressors on aquatic communities under environmental exposure scenarios. The method generates a probabilistic expression of the percent of an ecosystem's species at risk from a designated chemical exposure scenario.

A Construct Validation Study of the Personality Inventory for Youth (PIY) Using an Incarcerated Juvenile Population

A Construct Validation Study of the Personality Inventory for Youth (PIY) Using an Incarcerated Juvenile Population

Date: August 1997
Creator: Liff, Christine Denise
Description: The Personality Inventory for Youth (PIY) is a recently developed, multiscale assessment instrument designed specifically for adolescents between the ages of nine and 18. The purpose of this archival study was to establish clinical correlates for the PIY scales. PIY profiles were collected from 100 juvenile files at the Gainesville State School and examined in conjunction with the Child Assessment Scale (CAS) and the Personal Attitude Scale (PAS) to provide evidence of convergent and discriminant validity. Results indicate modest to moderate convergent validity according to Campbell and Fiske's criteria for construct validity; however, discriminant results indicate considerable overlap among traits which are not expected to be highly correlated.

A Continuation in the Defining of the Construct of Optimism

A Continuation in the Defining of the Construct of Optimism

Date: August 1997
Creator: Hinze, Travis Wayne
Description: One hundred twenty-two undergraduate students at the University of North Texas were administered several different optimism scales and also measures of similar constructs such as hope. Results indicated that most measures of optimism show only low to moderate intercorrelations with other measures of the same construct. Additionally, factor analysis confirmed that the measures of optimism actually appear to be assessing multiple factors and not necessarily optimism alone. Implications of the present study include the necessity of individual researchers to be familiar with the specific measure of optimism used in a given study as scores on differing measures of optimism may actually be providing very different information.

The Desires of Rebecca Horn: Alchemy and the Mechanics of Interpretation

The Desires of Rebecca Horn: Alchemy and the Mechanics of Interpretation

Date: August 1997
Creator: Dunlop, Douglas Donald
Description: The purpose of this thesis is to analyze the use of alchemy within the work of Rebecca Horn, to elucidate its presence in her work, and to illuminate its purpose as a personal philosophy and as a creative tool. The use of alchemy within Horn's work occurs as a process of revelation and transformation. Alchemy is revealed as a spiritual philosophy and as an interpretative system through the changes that occur in Horn's oeuvre. Throughout Horn's career, alchemy has developed into an interpretive system, a type of spiritual and cosmic perspective, that allows the artist to study, access, and meld diverse realities (sacred and profane) and diverse social systems (religious and scientific) into a more holistic and spiritually infused reality for herself and society-at-large. The purpose of her work is to help reinvest contemporary life with a spiritual presence by offering a model and a means of bringing the sacred into the profane.

Development of a Simplified Fracture Toughness Tool for Polymers

Development of a Simplified Fracture Toughness Tool for Polymers

Date: August 1997
Creator: Marnock, Patrick J. (Patrick Joseph)
Description: This thesis presents research toward the development of a simple inexpensive fracture toughness tool for polymeric materials. Experiments were conducted to test the specimen configuration and the fracture toughness tool against an established ASTM standard for polymer fracture toughness, D5045, and a commonly used four-point bend method. The materials used in this study were polycarbonate and high density polyethylene. Reductions in both the production time and the variability resulting from the preparation of the specimens were addressed through the use of specially designed fixtures. The effects from the razor cut depths used in the chevron notch were compared to the fracture toughness values obtained in order to determine the effect upon the validity of the fracture toughness.

A Dialectical Approach to Studying Long-Distance Maintenance Strategies

A Dialectical Approach to Studying Long-Distance Maintenance Strategies

Date: August 1997
Creator: Maguire, Katheryn C. (Katheryn Coveley)
Description: Using both qualitative and quantitative methodology, this thesis investigates the tactics used by long-distance relational partners, the differences in use of the tactics between long-distance and proximal partners, the relationship among the maintenance tactics, and the relationship of the tactics to relational satisfaction. Seven relational maintenance strategies were identified from the investigation: affirmation, expression, high tech mediated communication, low tech mediated communication, future thought, negative disclosure, and together-time. Significant differences in the use of maintenance tactics between long-distance and proximal partners were discovered and several tactics were found to correlate with relational satisfaction for both relationship types. It is concluded that relational maintenance should be viewed from a multi-dimensional perspective that recognizes the impact relational dialectics have on relationships.

Diane Di Prima: The Muffled Voice of the Beat Generation

Diane Di Prima: The Muffled Voice of the Beat Generation

Date: August 1997
Creator: Goggans, Heather
Description: The Beat rejection of conventional values meant a rejection of marriage, family, and a nine-to-five job, and few women were prepared to make that kind of radical shift in a society that condemned women for behaving the way the Beats behaved. Though she has faced difficulty in getting published, Beat writer Diane Di Prima has been publishing steadily for the past forty years. Di Prima has also lived the life of a Beat, wandering the country, avoiding nine-to-five work and supporting herself with grants, teaching and poetry readings. In spite of her success and adherence to the Beat lifestyle, Di Prima has given birth to five children, all of whom she took with her in her travels. Diane Di Prima has always faced the particular challenge of gaining the acceptance of her male peers amid indifference and hatred toward her sex while not allowing these men to go unanswered.
