From One To Many-Sided : Negotiating An Ethics Of Liberalism In Daniel Deronda, Anne Cecilia De Marzio

Theses, Dissertations and Culminating Projects

Following recent attempts in Victorian Studies to retrieve the broad critical rubric of liberalism, this essay aims to identify the substance under cultivation in the character of Gwendolen Harleth as many-sidedness. Gwendolen’s bildung has as its telos a disposition attaining to a regulative ideal of liberal agency; that is, she grows into a woman who aspires to sympathize with other vantage points. The ascesis which Eliot’s supreme egoist finally practices evidences not a being divested of her animating spirit and characterized by lack as other critics have argued, but one who has learned from Daniel to aspire to Goethe’s “lofty …

The Public Perception Of Enrichment For Captive Animals, Elizabeth Marie Webb

All Master's Theses

The effects of providing participants with educational information on enrichment as measured by the looking time at and ratings of zoo photographs were examined. One hundred and seventeen participants viewed photographs of zoo exhibits, 10 from each of the following categories: artificial exhibit with artificial enrichment, artificial exhibit with naturalistic enrichment, naturalistic exhibit with naturalistic enrichment, and naturalistic exhibit with artificial enrichment. Participants rated the photographs on exhibit aesthetic appeal, perceived animal happiness, and effectiveness of the enrichment. Pre- and posttest ratings of the importance of zoo roles were also collected. Results showed support for the hypothesis that participants provided …

Clouded Leopard Phylogeny Revisited: Support For Species Recognition And Population Division Between Borneo And Sumatra, Andreas Wilting, Valerie A. Buckley-Beason, Heike Feldhaar, Jurgen Gadau, Stephen J. O'Brien, K. Eduard Linsenmair

Biology Faculty Articles

Background

The clouded leopard (Neofelis nebulosa) is one of the least known cat species and depletion of their forested habitats puts it under heavy pressure. Recently reclassification of Bornean clouded leopards (N. nebulosa diardi) to species level (N.diardi) was suggested based on molecular and morphological evidence. Since the genetic results were based solely on three Bornean samples we re-evaluated this partition using additional samples of Bornean clouded leopards (N = 7) and we were also able to include specimens from Sumatra (N = 3), which were lacking in previous analysis.

The Effect Of Radiation And Repeated Sub-Culturing On Tgf-Β1 Signaling In Frtl-5 Cells, Cheryl G. Burrell

Loma Linda University Electronic Theses, Dissertations & Projects

From our ongoing in vitro studies using the Fisher Rat Thyroid cell line-5 (FRTL-5) we recorded accelerated growth, reduced follicularization and reduction in thyroxin release that occurred as the cells were repeatedly sub-cultured. We also recorded that these changes occurred earlier and more rapidly following radiation exposure. We determined that TGF-β1 production increased under both conditions. We hypothesized that alteration in the TGF-β1 signaling pathway contributed to the changes observed in the cellular properties of FRTL-5 cells. Our objective was to examine some of the players in the TGF-β1 signaling pathway to determine whether radiation and/or repeated subculturing promoted changes …

Radiation-Induced Increases In Pkc Modulate Integrin Expression And Contribute To Fibrotic Changes, Pinal Rushikesh Pandya

Loma Linda University Electronic Theses, Dissertations & Projects

The sequences of events in fibrosis are similar to those in wound healing; however, the normal termination and resolution stages do not take place. The initial cellular response following ionizing radiation involves accumulation of the ECM (extracellular matrix) including collagen, fibronectin and the interaction of many growth factors (cytokines) with their receptors. There are a number of unanswered questions regarding many aspects of radiation-induced fibrosis, including the initial triggers and physical changes that initiate the process. We have confirmed that elevated pKC and other cellular changes following radiation are similar to those found at sites of inflammation. This information leads …

Detoxification Of Lipopolysaccharide By Endodontic Sealers, Dominic Côté

Loma Linda University Electronic Theses, Dissertations & Projects

Bacterial lipopolysaccharide (LPS) has been implicated in the pathogenesis of pulpal and periapical diseases. Several studies have evaluated the ability of various medicaments and irrigants used during root canal therapy to chemically detoxify LPS. The purpose of this study was to evaluate the ability of some endodontic sealers to detoxify LPS. This investigation compared the quantities of TNF-α released by human monocytes exposed to LPS or LPS pre-treated with sealers. The sealers tested were: Pulp Canal Sealer EWT (PCS), AH Plus (AH), and Sealapex (SA). Ca(OH)₂ and water (H2O) were respectively used as the positive and negative control materials. …

Maturational Changes In Cerebrovascular Thick- And Thin-Filament Regulation, Renan Joel Sandoval

Loma Linda University Electronic Theses, Dissertations & Projects

The present study focused on the main hypothesis that age-related changes in myofilament Ca²⁺ sensitivity involve simultaneous changes in the relations between cytosolic Ca²⁺ transients, myosin phosphorylation, and force development. To define the effects of late fetal and early postnatal maturation, parallel experiments were carried out using cerebral arteries from both term lamb fetuses (140-141 days of gestation) and nonpregnant adult sheep. Fetal and adult cerebral arteries were stimulated by either mechanically, electromechanically, and/or pharmacomechanically-induced contractions, and the relations of cytosolic Ca²⁺, MLC phosphorylation, and contractile tensions were measured. These measurements allowed for stimulus and age-dependent …

Iron Dysregulation And Inflammation In Alzheimer’S Disease, Shino D. Magaki

Loma Linda University Electronic Theses, Dissertations & Projects

Alzheimer’s disease (AD) is the most common form of senile dementia in the US and worldwide but the causes of its pathogenesis are currently unknown. In this study, we examined two processes that have been implicated in the early stages of AD and other forms of neurodegeneration, iron dysregulation and inflammation, both of which can promote the increased production of amyloid precursor protein (APP). We have measured different pools of brain iron in transgenic iron regulatory protein 2 knockout (IRP2-/-) mice in the early stages of neurodegeneration and in affected brain regions from AD patients at different stages of the …

The Modifier Of Min 2 (Mom2) Locus: Embryonic Lethality Of A Mutation In The Atp5a1 Gene Suggests A Novel Mechanism Of Polyp Suppression., Amy A Baran, Karen A Silverman, Joseph Zeskand, Revati Koratkar, Ashley Palmer, Kristen Mccullen, Walter J Curran, Tina Bocker Edmonston, Linda D Siracusa, Arthur M Buchberg

Kimmel Cancer Center Faculty Papers

Inactivation of the APC gene is considered the initiating event in human colorectal cancer. Modifier genes that influence the penetrance of mutations in tumor-suppressor genes hold great potential for preventing the development of cancer. The mechanism by which modifier genes alter adenoma incidence can be readily studied in mice that inherit mutations in the Apc gene. We identified a new modifier locus of ApcMin-induced intestinal tumorigenesis called Modifier of Min 2 (Mom2). The polyp-resistant Mom2R phenotype resulted from a spontaneous mutation and linkage analysis localized Mom2 to distal chromosome 18. To obtain recombinant chromosomes for use in refining the Mom2 …

Furman'S Mythical Mandate, Scott W. Howe

University of Michigan Journal of Law Reform

This Article argues for the rescue and reform of Supreme Court doctrine regulating capital sentencing trials under the Eighth Amendment. Many legal commentators, both liberal and conservative, including several members of the Supreme Court, have concluded that the Court's regulation of capital sentencing trials is a disaster. The repeated criticisms rest on a commonly accepted view about a principal goal of capital sentencing regulation. The prevailing account, fueled by the rhetoric of the Justices, stems from the notion that Furman v. Georgia, 408 U.S. 208 (1972), revealed a mandate of consistency in the use of the death penalty that …

Us Department Of Agriculture, Wildlife Services, National Wildlife Research Center, Brian E. Washburn, Thomas W. Seamans

United States Department of Agriculture Wildlife Services: Staff Publications

Herbaceous vegetation comprises the main habitat type in cool-seasons grasslands and can be managed by various methods. We compared changes in plant communities and bird and mammal use of grasslands that were not managed, managed by mechanical methods (mowing), or managed by chemical methods (plant growth regulator). This 1-year study was conducted from May through October 2003 in Erie County, Ohio. Twelve circular 1.5 ha plots were established: 4 were not managed, 4 were mowed to maintain vegetation height between 9–15 cm, and 4 were sprayed with a plant growth regulator and mowed when vegetation exceeded 15 cm. We monitored …

Illusory Losses, Cass R. Sunstein

Coase-Sandor Institute for Law & Economics Research Paper Series

Recent empirical work demonstrates that people's self-reported happiness is surprisingly resilient to many large changes in life conditions; apparently significant adverse events and conditions often inflict little or no hedonic damage. People with disabilities—such as those on dialysis, with lost limbs, or with colostomies—appear to show the same level of happiness or life-satisfaction as people without disabilities. The reason for these results is people’s power of adaptation. Adaptation has several sources, but it is often a product of attention: Most of the time, people go about their lives without attending to, or focusing on, adverse conditions, and hence those conditions …

Interactions Between Physical And Virtual Space, Carolyn Hsu

Theses

Taking an in-depth look into how graphic design is used to successfully open doors to and encourage the journey through conceptual environments can provide an enhanced understanding of visual communication and visual perception in virtual spaces. This may lead to the creation of improved strategies for navigating through virtual environments, helping to create a system that will more closely reflect wayfinding and navigation in the physical world. Aspects of the study will include the visual translation of time, space, motion, and emotion through conceptual, spatial, and color considerations. Furthermore, understanding visual coding and other navigational aspects will involve the study …

A Tale In Motion; Ascended Learning, Stacey Houghton

Theses

The education of children in their early development is an essential time for them to develop their minds both cognitively and creatively. Reading, in particular, is one of the most important factors within this developmental stage, and thus needs to be fully grasped by children. A widening gap of illiteracy in America may be lessened by a more interactive and creative approach to learning. With the advent of the computer and motion graphics software, this thesis proves that there is now a more engaging way of educating our youth. Using the characters within the words to create imagery, rather than …

Red, White, But Mostly Blue: The Validity Of Modern Sunday Closing Laws Under The Establishment Clause, Lesley Lawrence-Hammer

Vanderbilt Law Review

On a Sunday morning, the average American might hope to enjoy any number of activities: attending a church service, drinking a mimosa with brunch, shopping for clothes at the mall, looking for a new car, or hunting with friends. However, in a surprisingly large number of states, only one of these activities would be legal: going to church.

Such is the result of blue laws,' the colloquial term for state statutes that regulate or prohibit entertainment and commercial activities on Sundays or religious holidays. Originating in England, blue laws were enacted throughout colonial America in an effort to protect the …

Multicellular Redox Regulation In An Early-Evolving Animal Treated With Glutathione, Joseph Doolen, Gabrielle Geddes, Neil W. Blackstone

Faculty Articles, Papers, and Other Scholarship

Redox signaling has emerged as a unifying theme in many seemingly disparate disciplines. Such signaling has been widely studied in bacteria and eukaryotic organelles and is often mediated by reactive oxygen species (ROS). In this context, reduced glutathione (GSH) acts as an important intracellular antioxidant, diminishing ROS and potentially affecting redox signaling. Complementing this cell-level perspective, colonial hydroids can be a useful model for understanding organism-level redox signaling. These simple, early-evolving animals consist of feeding polyps connected by tubelike stolons. Colonies treated exogenously with GSH or reduced glutathione ethyl ester (GEE) were expected to show a morphological change to sheetlike …

Stoichiometric Controls Of Mercury Dilution By Growth, Roxanne Karimi, Celia Y. Chen, Paul C. Pickhardt, Nicholas S. Fisher, Carol L. Folt

Dartmouth Scholarship

Rapid growth could significantly reduce methylmercury (MeHg) concentrations in aquatic organisms by causing a greater than proportional gain in biomass relative to MeHg (somatic growth dilution). We hypothesized that rapid growth from the consumption of high-quality algae, defined by algal nutrient stoichiometry, reduces MeHg concentrations in zooplankton, a major source of MeHg for lake fish. Using a MeHg radiotracer, we measured changes in MeHg concentrations, growth and ingestion rates in juvenile Daphnia pulex fed either high (C:P = 139) or low-quality (C:P = 1317) algae (Ankistrodesmus falcatus) for 5 d. We estimated Daphnia steady-state MeHg concentrations, using a …

Safe But Not Wholesome: The Troubling State Of Trans Fat Regulation, Ross Williams

Journal of Food Law & Policy

On March 7, 2007, the New York Times reported that Starbucks, the retail coffee chain which sells millions of baked goods every day from its over 8,700 U.S. stores, had asked its suppliers to eliminate all trans fats from their products by the end of the year. The big story for New York readers, though, was not that Starbucks was requiring the elimination of trans fats from its baked goods. In fact, New York City had just passed an ordinance strictly limiting the use of artificial trans fats, the type present in partially hydrogenated vegetable oil (PHVO), by virtually all …

Harvey V. Veneman And The National Organic Program: Can Organic Be Synthetic?, Jennifer C. Fiser

Journal of Food Law & Policy

The market for organic products has increased dramatically in the United States and across the world in recent years.' Since 1997, sales of organic foods have grown from 15% to 21% per year, and while organic foods accounted for only 2.5% of total food sales in the United States in 2005, those sales amounted to $13.8 billion.

Defying Nature: The Ethical Implications Of Genetically Modified Plants, Debra M. Strauss

Journal of Food Law & Policy

Genetic engineering is changing the semantics, the meaning of life itself. We're trying to usurp the plant's choice. To force alien words into the plant's poem, but we [have] a problem. We barely know the root language. Genetic grammar's a mystery.... We've learned a lot about the letters-maybe our ability to read and spell words now sits halfway between accident and design - but our syntax is still haphazard. Scrambled. It's a semiotic nightmare.

A Role For Sperm In Regulation Of Egg-Laying In The Nematode C. Elegans, Marie Mcgovern, Ling Yu, Mary Kosinski, David Greenstein, Cathy Savage-Dunn

Publications and Research

Background In insects and in mammals, male sperm and seminal fluid provide signaling factors that influence various aspects of female physiology and behavior to promote reproductive success and to compete with other males. It is less apparent how important such signaling is in the context of a self-fertile hermaphrodite species. We have addressed this question in the nematode Caenorhabditis elegans, which can reproduce either by hermaphrodite self-fertilization or by male-hermaphrodite mating.

Results We have studied the egg-laying defective mutant, egl-32, and found that the cellular basis of the egl-32 egg-laying phenotype is likely a defect in sperm. First, the time …

Effects Of Forage Management On Pasture Productivity And Phosphorus Content, M. M. Haan, J. R. Russell, J. L. Kovar, W. J. Powers, J. L. Benning

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The objectives of the current study were to determine the amounts of above- and below-ground plant biomass production, P uptake by forage, and P concentration of cool-season grass forage as influenced by management and season. Five forage management treatments were evaluated over 3 years in smooth bromegrass (Bromus inermis Leyss) pastures. Management practices were: ungrazed (U), hay harvest/fall stockpile grazing (HS), rotational stocking to residual sward heights of 10 (10R) or 5 (5R) cm, and continuous stocking to maintain sward height at 5 cm (5C). Forage samples were hand-clipped within and outside grazing exclosures monthly from April through November …

Sensory Deprivation Alters Aggrecan And Perineuronal Net Expression In The Mouse Barrel Cortex, Paulette A. Mccrae, Mary M. Rocco, Gail Kelly, Joshua C. Brumberg, Russell T. Matthews

Publications and Research

An important role for the neural extracellular matrix in modulating cortical activity-dependent synaptic plasticity has been established by a number of recent studies. However, identification of the critical molecular components of the neural matrix that mediate these processes is far from complete. Of particular interest is the perineuronal net (PN), an extracellular matrix component found surrounding the cell body and proximal neurites of a subset of neurons. Because of the apposition of thePNto synapses and expression of this structure coincident with the close of the critical period, it has been hypothesized that nets could play uniquely important roles in synapse …
