Surrounding Embryos: Biology, Ideology And Politics, Janet L. Dolgin Jan 2006

Surrounding Embryos: Biology, Ideology And Politics, Janet L. Dolgin

Hofstra Law Faculty Scholarship

This article considers several parameters of the late twentieth and early twenty-first-century debate in the U.S. about ethics, politics, science, and ideology (popularly referred to as the "culture wars"). The article focuses, in particular, on shifting understandings of the embryo. The article reviews developments in science (especially the advent of stem-cell research and cloning) that have affected understandings of embryo, the history of debate about abortion in the U.S., and the place of discourse about abortion in a more far-reaching social debate about family, personal relationships, and the scope of personhood in the U.S.

Landscapes Of Imagination: A Critical Analysis Of Art Textbooks, Lynda C. Kerr Jan 2006

Landscapes Of Imagination: A Critical Analysis Of Art Textbooks, Lynda C. Kerr

College of Graduate Studies: Theses & Dissertations

Author's abstract: This qualitative study examined imagination in secondary art textbooks, both historically and in the current educational climate. An arts-based inquiry, as described by Barone & Eisner (Jaeger, 1988), investigated how imagination is manifested in some art books, how the standards movement has tended to limit imagination in art textbooks, and how art textbooks could expand students' imaginations. Using a framework based on the theories of Dewey (1934/1980), Greene (2001), and Eisner (2002), four art textbooks were analyzed for their qualities which expand students' imaginations. The study described a design for an imaginative art textbook. Analysis focused on the …

Intra-Guild Compensation Regulates Species Richness In Desert Rodents: Reply, J. R. Goheen, Ethan P. White, S.K. Morgan Ernest, J. H. Brown Jan 2006

Intra-Guild Compensation Regulates Species Richness In Desert Rodents: Reply, J. R. Goheen, Ethan P. White, S.K. Morgan Ernest, J. H. Brown

Biology Faculty Publications

Null models have had a long and contentious history in community ecology (Connor and Simberloff 1979, Harvey et al. 1983, Gotelli and Graves 1996, Graves and Rahbek 2005). Much of this debate has arisen because multiple strategies for null models can be used to address a particular question of interest, and the present exchange is no exception. To assess constancy in species richness through time in a desert rodent community, Nichols et al. (2006) have proposed a Markov Chain model as an alternative to the random-walk model we developed (Goheen et al. 2005). While both null models simulate stochastic local …

The species-time relationship (STR) describes how the species richness of a community increases with the time span over which the community is observed. This pattern has numerous implications for both theory and conservation in much the same way as the speciesarea relationship (SAR). However, the STR has received much less attention and to date only a handful of papers have been published on the pattern. Here we gather together 984 community time-series, representing 15 study areas and 9 taxonomic groups, and evaluate their STRs in order to assess the generality of the STR, its consistency across ecosystems and taxonomic groups, …

The Offspring/Clutch Size Tradeoff In Mammals, E. L. Charnov, S.K. Morgan Ernest Jan 2006

The Offspring/Clutch Size Tradeoff In Mammals, E. L. Charnov, S.K. Morgan Ernest

Biology Faculty Publications

The Smith‐Fretwell model for optimal offspring size assumes the existence of an inverse proportional relationship (i.e., trade‐off) between the number of offspring and the amount of resources invested in an individual offspring; virtually all of the many models derived from theirs make the same trade‐off assumption. Over the last 30 years it has become apparent that the predicted proportionality is often not observed when evaluated across species. We develop a general allometric approach to correct for size‐related differences in the resources available for reproduction. Using data on mammals, we demonstrate that the predicted inverse proportional relationship between number of offspring …

Spectral Reflectance Of Canopies Of Rainfed And Subsurface Irrigated Alfalfa, Dennis Wayne Hancock Jan 2006

Spectral Reflectance Of Canopies Of Rainfed And Subsurface Irrigated Alfalfa, Dennis Wayne Hancock

University of Kentucky Doctoral Dissertations

The site-specific management of alfalfa has not been well-evaluated, despite the economic importance of this crop. The objectives of this work were to i) characterize the effects of soil moisture deficits on alfalfa and alfalfa yield components and ii) evaluate the use of canopy reflectance patterns in measuring treatment-induced differences in alfalfa yield. A randomized complete block design with five replicates of subsurface drip irrigation (SDI) and rainfed treatments of alfalfa was established at the University of Kentucky Animal Research Center in 2003. Potassium, as KCl, was broadcast on split-plots on 1 October 2004 at 0, 112, 336, and 448 …

Loss Of Escape-Related Giant Neurons In A Spiny Lobster, Panulirus Argus, Sandra Y. Espinoza, Lana Breen, Nisha Varghese, Zen Faulkes Jan 2006

Loss Of Escape-Related Giant Neurons In A Spiny Lobster, Panulirus Argus, Sandra Y. Espinoza, Lana Breen, Nisha Varghese, Zen Faulkes

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

When attacked, many decapod crustaceans perform tailflips, which are triggered by a neural circuit that includes lateral giant interneurons, medial giant interneurons, and fast flexor motor giant neurons (MoGs). Slipper lobsters (Scyllaridae) lack these giant neurons, and it has been hypothesized that behavioral (e.g., digging) and morphological (e.g., flattening and armor) specializations in this group caused the loss of escape-related giant neurons. To test this hypothesis, we examined a species of spiny lobster, Panulirus argus. Spiny lobsters belong to the sister taxon of the scyllarids, but they have a more crayfish-like morphology than scyllarids and were predicted to have escape-related …

Increased Hexosamine Biosynthesis And Protein O-Glcnac Protect Isolated Rat Heart From Ischemia/Reperfusion Injury, Jia Liu Jan 2006

Increased Hexosamine Biosynthesis And Protein O-Glcnac Protect Isolated Rat Heart From Ischemia/Reperfusion Injury, Jia Liu

All ETDs from UAB

Increased levels of protein-associated O-linked N-acetylglucosamine (O-GlcNAc) have been correlated with increased tolerance to stress. Therefore the goal of this study was to determine whether enhanced flux through the hexosamine biosynthesis pathway (HBP), which leads to elevated levels of O-GlcNAc, increased the tolerance of the heart to ischemia and reperfusion (I/R). Hearts from male rats were isolated and perfused with Krebs-Henseliet buffer containing 5mM glucose, and global, no-flow ischemia was induced for 20min followed by 60 min reperfusion. 20 min pre-treatment with 10 mM glucosamine, which enters the HBP directly, significantly improved functional recovery and decreased cardiac Troponin I release …

Regulation Of Ss-Catenin By Gli1 In Epithelial Transformation, Xingnan Li Jan 2006

Regulation Of Ss-Catenin By Gli1 In Epithelial Transformation, Xingnan Li

All ETDs from UAB

Gli family members-mediated continuous Hedgehog (Hh) pathway activity plays a role in the growth of a number of human cancers, including the common malignancy of skin, basal cell carcinoma (BCC), and other highly aggressive tumor types. However, the mechanism by which Gli proteins act to promote the outgrowth of cancer in response to stimulation of Hh signaling is poorly understood. Identified as zinc finger transcriptional factors, the Gli family of proteins has been shown to be involved in multiple cellular processes through activating its target genes. Therefore, to study the function of Gli target genes is important for our understanding …

Klf4 Regulates Notch1 Expression And Signaling During Epithelial Transformation, Zhaoli Liu Jan 2006

Klf4 Regulates Notch1 Expression And Signaling During Epithelial Transformation, Zhaoli Liu

All ETDs from UAB

Notch1 and KLF4 function in the specification of epithelial cell fates, and each can act as a context-dependent oncogene or tumor suppressor. We report that KLF4 directly regulates transcription of Notch1 and that cleavage of full-length Notch1 to the active intracellular form, N1IC, is necessary for transformation by KLF4. Paradoxically, KLF4 suppresses canonical Notch1-CSL signaling by up-regulating Hairless, an antagonist of this pathway. Dominant-negative inhibitors of the canonical Notch1 signaling pathway do not block transformation of epithelial cells by KLF4, while they greatly reduce the efficiency of transformation by N1IC. Thus, N1IC can transform cells by two distinct mechanisms: the …

Kiss1 Metastasis Suppressor Secretion Is Required For Metastasis Suppression, Kevin T. Nash Jan 2006

Kiss1 Metastasis Suppressor Secretion Is Required For Metastasis Suppression, Kevin T. Nash

All ETDs from UAB

Failure to reduce the number of cancer deaths over the last 50 years is due to the inability to selectively target metastatic disease. Recently, the KISS1 metastasis suppressor has emerged as a promising molecular agent for the management of metastatic disease. Although KISS1 has been implicated in the regulation of the metastatic phenotype in human cancers and in in vivo mouse models, little is known about its mechanism. Recent evidence suggests that KISS1 is a neuropeptide that is processed and secreted to interact with its cognate receptor GPR54 in the hypothalamus to trigger puberty and maintain the reproductive state. However, …

Intestinal Peptides And Ethnic Differences In Insulin Secretion, Paul B. Higgins Jan 2006

Intestinal Peptides And Ethnic Differences In Insulin Secretion, Paul B. Higgins

All ETDs from UAB

African Americans (AA) exhibit greater insulin responses following either an oral or intravenous glucose challenge relative to their European American (EA) counterparts. The etiology of this difference is not fully understood nor has it been confirmed with a more physiologically relevant mixed meal. Insulin secretion is regulated by a variety of factors. Significant among these are the enteric peptides glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). The role of the incretin system in the ethnic differences in post challenge insulinemia has received little attention. Hence, the purpose of the study was two-fold. First, determine whether AA have higher fasting …

Surface Reconstruction Using Gamma Shapes, Ying Sun Jan 2006

Surface Reconstruction Using Gamma Shapes, Ying Sun

All ETDs from UAB

Surface reconstruction from a set of sample points is important in many applications, including computer graphics, reverse engineering, computer vision and medical imaging. In this dissertation, several surface reconstruction techniques are investigated and the Alpha Shapes method is studied in detail. A new method, called Gamma Shapes, is introduced and implemented for reconstructing surfaces from a set of unorganized sample points. The Alpha Shapes method requires that the data point set be uniformly sampled in order to reconstruct an acceptable surface. Gamma Shapes method is an extension of the Alpha Shapes method with the advantage that the Gamma Shapes method …
