Revaluing The Literary Naturalist: John Burroughs's Emotive Environmental Aesthetics, Stephen Mark Mercier

Open Access Dissertations

This dissertation widens the circle of environmental aesthetics and ecocriticism by considering the role of the emotive in "appreciation." I demonstrate that emotion is a central feature in the literary naturalism of John Burroughs (1837-1921). Burroughs's model for environmental aesthetics combines narrative knowledge, sensory immersion, and emotional responses. Furthermore, I argue that Burroughs's "sentimental" emotions perform crucial roles in politics and therefore have serious implications for environmental consciousness. The rhetorical strategies inherent in Burroughs's paradigm for environmental aesthetics is essential to contemporary efficacious environmental discourse. This dissertation reclaims the importance of emotional affiliation with creatures, particularly birds, and their habitats. …

The Factors That Influence Middle-Level Teachers To Incorporate Community Service-Learning Into The Curriculum, Andrea J. Hainey-Turcotte

Open Access Dissertations

This study examined the factors that influence middle level educators to incorporate community service-learning into the curriculum. Eleven participants, each a teacher of middle level students, were interviewed to determine the extent to which they were influenced by intended outcomes for students, the community, and themselves. Findings suggest that participants were influenced to include community service-learning in the curriculum by anticipated benefits to students and community members. Participants hoped that by engaging in community service-learning activities, their students would become better scholars, leaders, citizens, and/or people. It would seem that participants were also driven to the implementation of community service-learning …

Evaluation Of Hot-Melt Extrusion Technology To Improve Dissolution Rates Of Poorly Water Soluble Drugs, Rina Chokshi

Open Access Dissertations

The bioavailability of orally administered drugs mainly depends on solubility and permeability. Since the advent of high throughput screening (HTS) in drug discovery process the resultant compounds are often high molecular weight and highly lipophilic, that show poor solubility. Scientists have tried to address solubility issues by various pharmaceutical interventions. Today amongst many methods available to improve solubility and dissolution rate, preparation of solid dispersions and solid solutions has gained enormous attention. Hot-melt extrusion is one of the most widely applied processing technologies in the plastic, rubber and food industry. Today this technology has found its place in the array …

The Role Of Glycolytic Substrates In The Initiation And Maintenance Phases Of Colonization Of The Mouse Large Intestine By Escherichia Coli Mg1655 And Escherichia Coli Edl933, Regina L. Miranda

Open Access Dissertations

Escherichia coli is a gram-negative motile rod, and is one of the most common bacterial strains isolated from the human intestinal tract (1,2). E. coli K-12, strain MG1655, is a non-pathogenic laboratory strain of E. coli whose genome has been fully sequenced (1). E. coli O157:H7, strain EDL933, a shigatoxin-producing E. coli (STEC), is a human pathogen, whose genome has also been fully sequenced (34). E. coli EDL933 was first isolated in August of 1982 from patients in the United States suffering from an outbreak of bloody diarrhea, which was traced to contaminated hamburgers (8,9,10,11). E. coli O157:H7 infections are …

An Assessment Of Predation By The Lobate Ctenophore Mnemiopsis Leidyi (Agassiz, 1865) On Ichthyoplankton In Narragansett Bay, Rhode Island, Angela R. Allen

Open Access Master's Theses

I investigated the importance of predation on fish eggs and larvae by the lo bate ctenophore, Mnemiopsis leidyi, in Narragansett Bay, RI, USA, by measuring the abundance and distribution of M. leidyi and its ichthyoplankton prey at five stations in the East and West Passages of the bay from May to August, 2002. During early-June, the M. leidyi population reached an abundance of 682 m^-3 in the mid-bay, while fish egg densities were 3.2 m^-3 and fish larvae were absent. In late June, a maximum larval fish density of 34 100m^-3 was observed, and ctenophore abundance …

Assessment Of Problem-Solving Abilities In Normal Adolescents, Kelley Ann Crownover

Open Access Master's Theses

This study examined the problem-solving abilities of adolescents, using a newly designed test, RAPS (the Rapid Assessment of Problem-Solving), by Marshall & Karow (2001). The tool is a modified version of the Twenty Questions Test that measures performance based on the number of questions asked to solve each problem, the percent of constraint-seeking questions used, and the efficiency or the amount of information gained from the first four questions asked. Participants included a total of 20 children with no history of neurological or psychiatric disorders who were categorized by age groups (10-11, 12-13, 14-15, and 16-17) with five subjects in …

Global Climate Change And Shifting Sea Ice: Planning For New Fishery Development In The Arctic, Kimberly Anne Lellis

Open Access Master's Theses

This thesis examines the implications of global warming for fisheries management in the Arctic waters off Alaska. In particular, the purpose of this thesis is to ascertain the current level of awareness, concern, and planning by physical scientists, social scientists, and federal and state resource managers for a potential future scenario that could develop in Alaska if: 1) warming ocean temperatures cause an expansion or a shift in the ranges of commercial fish species; and 2) the retreat of sea ice due to climate change allows commercial fishing fleets to expand into new areas such as the Chukchi Sea. Commercial …

Effects Of Food Consumption And Temperature On Growth Rate And Biochemical-Based Indicators Of Growth In Early Juvenile Atlantic Cod Gadus Morhua And Haddock Melanogrammus Aeglefinus, Myron Arms Peck, Lawrence J. Buckley, Elaine M. Caldarone, David A. Bengtson

Fisheries, Animal and Veterinary Sciences Faculty Publications

The relationship between the somatic growth rate (G) and feeding level (unfed, intermediate, and maximum rations) of age-0 juvenile cod Gadus morhua and haddock Melanogrammus aeglefinus was quantified at different temperatures. Laboratory trials were conducted using 2 sizeclasses of cod (3.6 to 5.6 cm standard length [SL], and 8.1 to 12.4 cm SL) at 5, 8, 12, and 15°C, and 1 size-class of haddock (6.0 to 9.6 cm SL) at 8 and 12°C. The shape of the growth-feeding relationship was well described by a 3-parameter asymptotic function for cod and by a linear function for haddock (R² range …

Mobile Technologies And Boundaryless Spaces: Slavish Lifestyles, Seductive Meanderings, Or Creative Empowerment?, Nikhilesh Dholakia, Detlev Zwick

College of Business Faculty Publications

According to the instrumental theory of technology, mobile technologies - what McLuhan's refers to as electronic prostheses - promise opportunities for greater freedom, creativity, leisure, and productivity by enhancing organic bodily functions. Correspondingly, as (Cavallaro, 2000) would argue, objects such as mobile phones, personal digital assistants (PDAs), portable physiotherapy units, laptops, and portable stereos - to name just a few - seem to impart a sense of solidity to consumers' lives. Just like prostheses, they are inserted into our everyday lives, helping our "inadequate" bodies along in fulfilling practical tasks. Phenomenologically, these kinds of mobile technologies supposedly support the subject's …

Impact Of Ectoparasites On The Demography Of A Small Reef Fish, Rachel J. Finley, Graham E. Forrester

Natural Resources Science Faculty Publications

In marine systems, empirical studies demonstrating effects of macroparasites on host population dynamics are relatively few. We tested the effects of a copepod macroparasite infecting the gills of a small coral reef fish, the bridled goby Coryphopterus glaucofraenum. Fish that were naturally infected and uninfected were tagged as individuals and tracked in the field for 5 mo. Parasitism was associated with an increase in gill ventilation rate, and a reduction in feeding. More importantly, parasitized fish showed significantly reduced growth (by 66%) and gonad mass (by 68%) compared to uninfected fish, and parasitism increased instantaneous mortality by a factor …

Cloning Of A Salivary Gland Metalloprotease And Characterization Of Gelatinase And Fibrin(Ogen)Lytic Activities In The Saliva Of The Lyme Disease Tick Vector Ixodes Scapularis, Ivo M.B. Francischetti, Thomas N. Mather, José M.C. Ribeiro

Past Departments Faculty Publications (CELS)

The full-length sequence of tick salivary gland cDNA coding for a protein similar to metalloproteases (MP) of the reprolysin family is reported. The Ixodes scapularis MP is a 488 amino acid (aa) protein containing pre- and pro-enzyme domains, the zinc-binding motif HExxHxxGxxH common to metalloproteases, and a cysteine-rich region. In addition, the predicted amino-terminal sequences of I. scapularis MPs were found by Edman degradation of PVDF-transferred SDS/PAGE-separated tick saliva proteins, indicating that these putative enzymes are secreted. Furthermore, saliva has a metal-dependent proteolytic activity towards gelatin, fibrin(ogen), and fibronectin, but not collagen or laminin. Accordingly, I. scapularis saliva has a …

The Construction Of An Est Database For Bombyx Mori And Its Application, Kazuei Mita, Mitsuoki Morimyo, Kazuhiro Okano, Yoshiko Koike, Junko Nohata, Hideki Kawasaki, Keiko Kadono-Okuda, Mikiko Yamamoto, Masataka G. Suzuki, Toru Shimada, Marian R. Goldsmith, Susumu Maeda

Biological Sciences Faculty Publications

To build a foundation for the complete genome analysis of Bombyx mori, we have constructed an EST database. Because gene expression patterns deeply depend on tissues as well as developmental stages, we analyzed many cDNA libraries prepared from various tissues and different developmental stages to cover the entire set of Bombyx genes. So far, the Bombyx EST database contains 35,000 ESTs from 36 cDNA libraries, which are grouped into ≈11,000 nonredundant ESTs with the average length of 1.25 kb. The comparison with FlyBase suggests that the present EST database, SilkBase, covers >55% of all genes of Bombyx. The …

Buddhist Perspectives And Human Communication, Rueyling Chuang, Guo-Ming Chen

Communication Studies Faculty Publications

This paper examines the connection between Buddhist essential teachings and human communication in the East Asian context. The essential Buddhist essential teachings, including the perception of reality, living the present moment and mindfulness, compassion, the four noble truths, and the six paramitas are first delineated. The paper then analyzes how these Buddhist teachings influence East Asian communication behaviors from five perspectives: ontological assumptions, communication ethics, communication behaviors, relationship development, and rhetorical communication. It is concluded that although Buddhist teachings show great impact on the life of East Asians, the influence of other religions and thoughts should not be ignored.

Relationship Between Reproductive Success And Male Plasma Vitellogenin Concentrations In Cunner, Tautogolabrus Adspersus, Lesley J. Mills, Ruth E. Gutjahr-Gobell, Doranne Borsay Horowitz, Nancy D. Denslow, Marjorie C. Chow, Gerald E. Zaroogian

Past Departments Faculty Publications (CPHARM)

The gene for vitellogenin, an egg yolk protein precursor, is usually silent in male fish but can be induced by estrogen exposure. For this reason, vitellogenin production in male fish has become a widely used indicator of exposure to exogenous estrogens or estrogen mimics in the aquatic environment. The utility of this indicator to predict impacts on fish reproductive success is unclear because information on the relationship between male plasma vitellogenin and reproductive end points in male and female fish is limited. In the research reported in this article, we investigated whether the presence of male plasma vitellogenin is a …

Intracellular Dynamics Of Lead And Calcium In Lead-Exposed Cultured Neurons Of Aplysia Californica (Mollusca: Opisthobranchia), Catherine T. Tamse

Open Access Dissertations

The neurotoxin lead (Pb2+) is a continuing health and environmental problem. However, its neurotoxic mechanism remains unclear. Since calcium (Ca2+) is vital in cellular processes and with Pb2+ reported to interfere with Ca2+-mediated processes, the hypothesis that Pb2+ subverts Ca2+ homeostasis by entering cells through Ca2+ transport pathways and displacing intracellular Ca2+ ([Ca2+] i) was investigated. A multi-technique approach tested this hypothesis. Using cultured Aplysia bag cell neurons, changes in transmembrane Ca2+ flux after Pb2+ exposure were directly measured with the Ca2+-selective self-referencing electrode. Cumulative concentrations of extracellular Pb2+ produced a corresponding and significant (P < 0.05) increase in Ca 2+ efflux, independent of time exposure. Ca2+ channel blockers Co2+, La3+, and verapamil inhibited Pb2+-induced flux. The sarco/endoplasmic reticulum Ca 2+-ATPase pump inhibitors, thapsigargin and cyclopiazonic acid, both elicited a Ca2+ efflux reflecting inhibition of ER pumps and [Ca2+]i release. Furthermore, Pb2+ evoked a moderate and sustained elevation in thapsigargin-stimulated Ca 2+ efflux. For morphological evidence that Pb2+ can mobilize [Ca 2+]i, potassium pyroantimonate (KPA) cytochemistry of bag cells were analyzed. 2% KPA resulted in widespread electron-dense precipitates. 10 mM EGTA + KPA or 200 μM Pb2+ + KPA both produced marked reductions of precipitates in neurons. X-ray microanalysis confirmed antimony (Sb) in precipitates but could not separate the overlapping Ca2+-Sb spectral peaks. However, reduced precipitates in EGTA-incubated cells indicate presence of Ca2+ in intracellular precipitates observed. No apparent pathological changes were correlated to Pb2+ exposure. The effects of Pb2+ on [Ca2+]i using the fluorescent Ca2+ indicator, chlortetracycline (CTC), was examined. Control neurons incubated in 10 μM CTC demonstrated extensive yellow-green fluorescence while reduced fluorescence intensities were seen in cells exposed to 200 μM Pb2+. Multi-sized punctate fluorescence were observed along the perimeter and sometimes, throughout the soma. No neuronal autofluorescence nor neuritic fluorescence in control and Pb2+-exposed cells were detected. Average fluorescence intensities between control and Pb2+-exposed neurons were statistically significant (P < 0.0005). Collectively, these results are consistent with the hypothesis that Pb 2+ perturbs Ca2+ homeostasis via mobilization of [Ca 2+]i. Pb2+ operates through Ca2+ transport pathways as shown by changes in transmembrane Ca 2+ flux, in KPA precipitate reactions, and in CTC fluorescence.
