Water Column Ammonium Concentration And Salinity Influence Nitrogen Uptake And Growth Of Spartina Alterniflora, Rachel Mactavish Jan 2014

Water Column Ammonium Concentration And Salinity Influence Nitrogen Uptake And Growth Of Spartina Alterniflora, Rachel Mactavish

College of Graduate Studies: Theses & Dissertations

Salt marsh macrophytes, such as Spartina alterniflora, play a critical role in uptake and transformation of inorganic nitrogen before it reaches coastal waters, thereby reducing the potential for eutrophication. Although nitrogen availability typically limits S. alterniflora growth, it may be possible to exceed the nitrogen uptake capacity of S. alterniflora. Increasing either nitrogen concentrations or salinity are key factors regulating S. alterniflora nitrogen uptake. Investigating the effects of nutrients and salinity on S. alterniflora is important given that increases in inorganic nitrogen supply to surface waters from agriculture and urbanization occur simultaneously with freshwater withdrawals that reduce flow and increase …

Success And Failure In Adr: A Dialogue Between Partners, Lela P. Love, Joseph B. Stulberg Jan 2014

Success And Failure In Adr: A Dialogue Between Partners, Lela P. Love, Joseph B. Stulberg

Articles

Love and Stulberg critically discuss policy, scholarly, and practice developments in four areas of program development in the area historically referenced as alternative dispute resolution (ADR): the range of process options; the impact of court procedures on ADR program development and practice; the nature of ADR scholarship and training; and the general public's receptiveness to or rejection of the normative principles that structure ADR collaborative processes. Their concluding remarks suggest that the promise of ADR, particularly of the mediation process, remains inspiring to many, even if its effective implementation remains uneven.

To Destroy Or To Preserve: Urban Renewal And The Legal Foundation Of Historic District Zoning, Andrew Tarne Jan 2014

To Destroy Or To Preserve: Urban Renewal And The Legal Foundation Of Historic District Zoning, Andrew Tarne

Theses and Dissertations

Historic preservation and urban renewal are often thought to be polar opposites. Where one seeks to preserve, the other generally seeks to destroy in order to rebuild. While the programs appear on the surface to be in opposition, this Thesis seeks to demonstrate that there is a fundamental connection between the underlying legal principles of historic zoning and urban renewal. To that end, the jurisprudence involving historic zoning and aesthetic regulations before and after the seminal urban renewal case of Berman v. Parker has been collected and analyzed. This analysis revealed that courts were hesitant to support aesthetic, and by …

An Analysis Of Fatty Acid Metabolism’S Role In The Development Of Acute Functional Tolerance To Ethanol In Caenorhabditis Elegans, Richard Raabe Jan 2014

An Analysis Of Fatty Acid Metabolism’S Role In The Development Of Acute Functional Tolerance To Ethanol In Caenorhabditis Elegans, Richard Raabe

Theses and Dissertations

An individual’s naïve level of response (LR) to ethanol is predictive of their lifetime likelihood to abuse alcohol. LR is heavily genetically influenced, suggesting that the genes responsible for LR may also be central to the development of abuse disorders. Our laboratory uses the model organism C. elegans to investigate the genetic influences on responses to acute ethanol exposure. We recently found that changes in TAG levels can alter LR. From this result we investigated the role of long-chain polyunsaturated fatty acids (LC-PUFAs) as well enzymes involved in lipid modifications of proteins. We found that LC-PUFAs are necessary for acute …

A Mixed-Methods Examination Of Racial Differences In Females' Perceptions And Experiences Of Sexual Objectification, Ellyn Leighton-Herrmann Jan 2014

A Mixed-Methods Examination Of Racial Differences In Females' Perceptions And Experiences Of Sexual Objectification, Ellyn Leighton-Herrmann

Theses and Dissertations

Sexual objectification has become a pervasive problem, negatively affecting the mental and physical health of many women. Understanding the influence of visual media, social-support networks and social interactions on young women's health is essential to addressing issues related to objectification. We do not have an in-depth understanding of how Black and White young adult women make meaning of objectification. Further, the existing literature suggests that experiences of objectification are likely different for Black and White women. The current research employed two studies, one qualitative and one quantitative, to address these particular gaps. Study 1 used focus groups to assess young …

The Cytotoxic Effect Of The Bcl-2 Family Of Proteins In Breast Cancer Cells, Yamileth Chin Jan 2014

The Cytotoxic Effect Of The Bcl-2 Family Of Proteins In Breast Cancer Cells, Yamileth Chin

Theses and Dissertations

Breast cancer is the second leading cause of death amongst women ages 20 to 59. Despite advancements in cancer therapies, more research is necessary to improve the diagnoses and treatment of several types of breast cancer. Paclitaxel (Taxol) is a commonly utilized anti-cancer drug for various types of solid tumors. However, the molecular mechanism utilized by paclitaxel to induce cell death is still elusive. Previous studies in our laboratory have shown that the pro-apoptotic BCL-2 family protein, BAK (BCL-2 homologous antagonist/killer) plays an important role in paclitaxel-induced cell death. In untreated breast cancer cells, BAK is associated with the anti-apoptotic …

Evaluating The Antibody Response Against Ospa, Ospc, And Ospe Recombinant Proteins Over Time In Borrelia Burgdorferi Positive Serum Samples, Bridget Dillon

Theses and Dissertations

Lyme disease is the most common tick-borne illness in North America. It can be hard to detect using blood tests, especially in the early stage. Due to the number of significant complications from untreated or undertreated Lyme disease, better methods need to be found to detect the disease. Some surface lipoproteins may be used to detect early disease due to their early expression. Others are maintained for the duration of the infection and can be used to detect chronic Lyme disease. Antibody responses to OspA, OspC and OspE were measured in sera from experimentally infected dogs. The response to OspA …
