The Finescale Distribution, Origin, And Photobleaching Of The Spectral Absorption Of Dissolved Organic Matter In Coastal Waters, Michael Stewart Twardowski

Open Access Dissertations

Accurate, finescale absorption profiles of colored dissolved organic matter (CDOM) were measured in coastal waters. CDOM has also been called Gelbstoff, gilvin, yellow substances, hurnic substances, and "unknown chromophores". The processes responsible for the observed temporal and spatial variability were investigated. The sources of CDOM were diluted inputs from the terrestrial biosphere and in situ biological processes. The primary sink was photodegradation.

The finescale distribution of inherent optical properties was measured with a WET Labs ac-9. The ac-9 is an innovative in situ absorption and attenuation meter with a precision about ± 0.001 m-1 in the raw signal. A pressurized …

An Application Of Dynamic Factor Analysis: An Examination Of Smoking Habit Strength Measures, Brett A. Plummer

Open Access Master's Theses

Across smoking cessation studies, a variety of self-report and physiological measures have been used as outcome measures attempting to operationalize the degree of "habit strength " people experience. However, the performance of these different measures has not been adequately assessed longitudinally (Velicer, Rossi, Prochaska, & DiClemente, 1996). Employing time-series data to understand underlying physiological and/or psychological processes is a useful way to study constructs which may fluctuate daily. Although it has been applied in an extremely limited number of settings, dynamic factor analysis is one statistical method which may help to evaluate habit strength measures over time. This study has …

Developing A Theoretical And Empirical Ethnocultural Model Toward Predicting Crying Behavior In White College Women, Brian L. Ragsdale

Open Access Master's Theses

Self reported crying behavior in White college women along with ethnocultural variables which may influence their crying behavior was examined. Another focus of the study was to begin the development of an ethnocultural survey of crying behavior. Questions concerning socioeconomic status, religiosity/ spirituality, interpersonal experiences, family members feeling about crying behavior, perceptions of same race and other race crying, White Racial Identity Attitude (Helms, 1990) and the East/ West Questionnaire (Gilgen & Cho, 1979) were used as ethnocultural variables.

One hundred sixteen White women completed the survey during the first administration and sixty three of them completed the survey during …

Assessing Predictors Of Smoking Cessation: An Application Of Signal Detection Methodology, Sonya V. Benisovich

Open Access Master's Theses

Cigarette smoking is a leading cause of preventable illness and death in the United States. Yet, when people are able to quit, the negative effects of smoking to their health diminish over time. For this reason, it is important for behavioral scientists to understand the mechanisms which underly smoking cessation. In this study, signal detection analysis was used to determine which baseline characteristics of 602 smokers were best able to discriminate those who had quit smoking from those who had not six and eighteen months later. Variables included in this analysis were chosen based on prior research showing that they …

Isolation Of The Virulence Gene(S) In The New, Live, Oral Vaccine Candidate Salmonella Typhimurium Sr-11 Fad, James H. Allen

Open Access Master's Theses

A DNA fragment containing the defective virulence gene(s) in the live oral vaccine candidate Salmonella typhimurium SR-11 Fad was isolated. Genomic DNA fragments from the vaccine candidate, constructed by Tn10d::cam transposon mutagenesis, were probed with the 1.4 Kbp chloramphenicol resistance gene contained in Tn10d::cam and analyzed by Southern hybridization. Two of the fragments, an 8.0 Kbp Hind III fragment and a 4.5 Kbp Pst I fragment, were isolated, cloned into E. coli HB 101, and mapped. The Pst I fragment, containing approximately 2.9 Kbp of flanking genomic DNA, was subcloned into the sequencing vector pBluescript …

Land Use Regulation, Takings Legislation, And The Wise Use Movement In Six States, Ronald M. Wolanski

Open Access Master's Theses

This project is the culmination of several months of research and data analysis on the Wise Use movement and takings legislation in six states (Kansas, Maine, Mississippi, Montana, Oregon, and Rhode Island). The aim of the research was to determine the relationship, if any, between the strength of environmental and land use regulation in the states and the prevalence of takings legislation. With a better understanding of the relationship of these factors, legislators, regulators, and planners will be better able address the concerns of constituents. My hypothesis was that the prevalence and strength of takings or property rights legislation is …

North Stonington Village: Ensuring A Sense Of Place, Jennifer M. Lutke

Open Access Master's Theses

The purpose of this research project is to determine how North Stonington, Connecticut, can best protect and enhance the character of North Stonington Village through land development regulations.

The character of North Stonington Village is in jeopardy as a direct result of its current land development regulations. Stated in both the North Stonington Zoning Regulations (1985) and, indirectly, in the North Stonington Plan of Development (1981), the citizens of North Stonington desire to protect and enhance the Village's character to ensure its unique sense of place.

The main product of this work is a proposed Village District. This district, if …

A Study Of The Rheological Properties Of Some Of The Gels Commonly Used In The Pharmaceutical, Food And Cosmetic Industries And Their Influence On Microbial Growth, Jorge A. Mendoza

Open Access Master's Theses

In the first paper of this work, lambda and kappa carrageenan, guar gum, Water Locks A-100 and DD-223 and Carbopol 971 were selected based on their rheological properties to study of the effects of gel concentration, osmotic pressure and rheological properties as determined by oscillatory viscometry on the growth rate of Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus and Candida albicans. The object of this study was to determine the contributions of gel rheology on the growth of microorganisms that commonly contaminate such gels, and assess the influence of the rheology on their self-preserving properties. The rheological properties of the …

Relationship Between Attachment And Out-Of-Home Placements In Emotionally And Behaviorally Disordered Male Adolescents, Gail M. Curran

Open Access Master's Theses

Since its inception, Bowlby's attachment theory has guided research in the area of attachment. A body of literature supports the conclusion that when attachment needs are not met in the first year of life, serious deficits and problems can occur. The present study adds to the existing literature by examining attachment in adolescents, an age group not frequently researched. Specifically, this study examines the relationship between attachment and multiple out-of-home placements for adolescent males living in a residential treatment facility.

In order to understand the characteristics of youth living in a residential treatment facility, an archival search was completed to …

Logiccity: On-Line Digital Logic Simulator, Jihad Z. Almahayni

Open Access Master's Theses

A primary challenge for science educators is to develop ways to help students understand new ideas that cannot be directly observed. The application of computer simulations is one method instructors may use to address the problem of teaching for conceptual understanding. The use of computer simulations for science teaching is increasing steadily because simulations provide students with the opportunity to witness or "perform" experiments that might otherwise be too expensive, too time consuming, or too dangerous for them to do in the lab. Simulation, in general, is a very effective way for both a student and a professional to visualize …
