In Situ Detection Of Tbx5 Expression In Developing Chick Embryonic Heart, Vaishali Agarwal

Master's Theses

The Tbx 5 gene codes for a highly conserved transcription factor containing a DNA-binding motif called the T box (or T-domain). Tbx 5 is expressed in the posterior sinoatrial segment of the heart along with the developing forelimb buds. Mutations in Tbx 5 gene are associated with Holt Oram Syndrome (HOS), which is characterized by heart septal defects and forelimb abnormalities. Tbx 5 expression was examined during various stages of heart development in chick embryos using both a double stranded digoxygenin-labeled DNA probe and a single stranded digoxygenin-labeled anti-sense RNA probe (riboprobe). Due to the presence of homology in the …

Courtship And Copulation In Glaucous-Winged Gulls, Larus Glaucescens, Kelly M. Mcwilliams

Master's Theses

Using video recordings and scan counts, I examined the occurrence, sequences, and durations of behavior and environmental factors associated with courtship and copulation in glaucous-winged gulls, Larus glaucescens. Males and females in a pair had equivalent pre- and post-Mount behavior occurrences and durations. The main courtship sequence was Head Toss -- Courtship Beg/Respond -- Mounted/Mount, and felames appeared to initiate transitions between these pre-Mount behaviors. More Mounts occurred during the egg-laying stage of the breeding season, but copulation duration, wing-flag duration, and cloacal contacts per copulation showed no significant differences across sampling periods. Poisson analysis showed no significant grouping …

Habitat Conditions And Steelhead Abundance And Growth In A California Lagoon, Kristine Ann Atkinson

Master's Theses

To better understand the temporal and spatial relationships of water quality parameters, as well as steelhead (Oncorhynchus mykiss) habitat use and growth in San Gregorio Creek estuary / lagoon, water quality and steelhead at San Gregorio Creek estuary / lagoon were studied over a period of two years. During both years, there was above-average rainfall, and during the dry seasons of both years the lagoon was repeatedly artificially breached. In spite of the breaching, variations in growth and population size relative to variable sandbar dynamics were measured both within and between years. Data showed that repeated artificial breaching …

Voltaire Et Le Sauvage Civilisé, Christopher J. Barros

Master's Theses

This thesis explores Voltaire's interpretation of human nature, society, and progress vis-à-vis the myth of the "noble savage," an image that was widespread in the literature, imagination, and theater of the 17th and 18th centuries. For many people at that time, the "bon sauvage" embodied a certain happiness, simplicity, and equality that were lost when humankind exited its "primitive" state and became "civilized." Rousseau's "Discours sur l'origine et les fondements de l'inégalité parmi les hommes," which was vehemently criticized by Voltaire, greatly popularized the myth of primeval bliss, a myth which is still with us today.

In various works by …

The Distribution Of Gnrh And Erbeta In Pre- And Post-Pubertal Male Rats, Maysaa Nageeb

Master's Theses

The hypothalamic-pituitary- gonadal axis is intrinsic in regulating reproductive function. Each part orchestrates the synthesis and release of a key hormone. At the level of the hypothalamus, Gonadotropin- releasing hormone (GnRH) is released and it is the

most upstream regulator of sexual maturation. GnRH neurons express a type of estrogen receptor, ERbeta, which suggests that estradiol (E2) plays a direct role in modulating GnRH function (Herbison and Pape 2001). The objective of this study was to determine if gonadal steroid hormones regulate the expression of ERbeta and GnRH mRNA in the male brain during pubertal development. In-situ hybridization was used …

Messages Of Nationalism In Mexican And U.S. Textbooks: Implications For The National Identity Of Transnational Students, Danielle Lane Jerdee

Master's Theses

This study uses qualitative content analysis to compare fifth grade social studies textbooks in Mexico and the United States to provide insight on how messages of national identity change as students migrate between school systems. The following research questions will guide the analysis: Given that one of the roles of textbooks is to form a national consciousness through mythmaking, how do messages of national identity conveyed in Mexican and U.S. textbooks conflict? How are the topics of immigration and citizenship presented in each nation's textbooks? In what ways do differences in the accounts of history between Mexico and the United …

Gender Stereotypes In Public School Textbooks In The Dominican Republic, Karie Jo Karasiak

Master's Theses

In 1992, the Secretary of Education of the Dominican Republic set an objective of eliminating gender stereotypes that discriminate against women from textbooks (Díaz Santana, 1996; Mateo Diclo, n.d.). My research is a historical comparison of two sets of texts published in the years 1996-1997 and 2005-2007 focusing on visual representations portraying gender roles with the purpose of ascertaining if progress is being made towards this objective. I analyze a total of six books, three books from 1996-1997 and three from 2005-2007. The examined textbooks include two second grade Natural Sciences, two fourth grade Spanish, and two sixth grade Social …

Law And Its Order, Daniele Manni

Master's Theses

Daniele Manni

Loyola University Chicago

LAW AND ITS ORDER: THE PRIORITY OF ETHICS OVER LEGISLATION

IN PLATO'S LAWS.

Despite the fact that the Laws are almost twenty four hundred years old, their reserve of philosophically and politically interesting points is still copious and relevant for the contemporary reader. The present work is an initial attempt to analyze the nature of law as treated in the Laws and to highlight especially the reliance of the legislative sphere on the ethical sphere.

In spite of the many, and often painfully detailed, laws posited by the Athenian in the course of books VIII-XII, …

Reorientation Through Interruption: On The Relation Of Immanuel Kant's Modes Of Egoism To His Critical Philosophy, Giancarlo Tarantino

Master's Theses

The relationship between Immanuel Kant's anthropology, and his Critical philosophy has proven to be a notoriously difficult problem, both for specifically Kantian scholarship as well as for philosophy in general. This thesis attempts to investigate this relationship by showing the importance of Kant's modes of egoism at work in his three Critiques. In doing so this thesis will highlight the phenomena of interruption, and orientation as playing crucial interpretive roles for parsing out the aforementioned relationship. I will try to show that anthropology and Critique mutually interrupt, and re-orient one another's specific contributions to the major themes of Kant's thinking.

Posttraumatic Stress Symptom Clusters And Externalizing Problems In Young Urban African American Adolescents, Maria Ann Horn-Rollins

Master's Theses

The purpose of this study was to investigate the associations between five posttraumatic stress symptom (PTSS) clusters and two forms of externalizing problems within and across the middle school years in a low income urban sample of young adolescent African Americans. A secondary aim of this study was to explore moderation effects by gender. Total PTSS positively predicted a little over 58% of the cross-sectional externalizing outcomes and uniquely explained between 5 and 12% of the variance in these outcomes over and above gender and exposure to violence. Total PTSS significantly and positively predicted one-third of the longitudinal outcomes and …

Predictors Of Mental Health Outcomes Among Foster Care Children Receiving Community-Based Services, Alison Merri Dunleavy

Master's Theses

Historically, children served in the foster care system experience less favorable mental health outcomes compared to those in the general population (Anctil, McCubbin, & Pecora, 2006; Burns et al., 2004; Garland et al., 2001; Zima, Bussing, Yang, & Berlin, 2000). As a result, the child welfare system has been described as a "de facto public behavioral health care system" (Lyons & Rogers, 2004), prompting state child welfare agencies to seek to put systems and policies in place to serve the needs of these youth, such as Illinios' statewide community-based program, System of Care (SOC), designed to provide multi-modal services to …

Resource Composition And Macroinvertebrate Resource Consumption In The Colorado River Below Glen Canyon Dam, Holly Ann Alfreda Wellard Kelly

Master's Theses

Physical and biological changes to rivers induced by large dams can significantly alter downstream communities, decreasing the biotic integrity of these rivers. For example, completion of Glen Canyon Dam on the Colorado River in 1963 has altered the downstream ecosystem and contributed to the decline of native fish populations and dramatic changes in the macroinvertebrate communities. Physical changes associated with the dam may also influence the food resources supporting macroinvertebrate production, but this has not been previously measured. For example, autochthonous production is high in the clear tailwaters of the dam, but downstream tributary allochthonous carbon inputs are substantial and …

Structure-Function Relationship Studies Of The Udp-Glucose Pyrophosphorylase From Escherichia Coli, Agnieszka Maria Orlof

Master's Theses

UDP-Glucose Pyrophosphorylase (UDP-Glc PPase) is a key enzyme of the carbohydrate metabolic pathway widely used among prokaryotes and eukaryotes. In plants, UDP-Glc PPase is necessary for sucrose synthesis while mammals utilize this enzyme for the production of glycogen. A bacterium such as Escherichia coli uses UDP-Glc PPase for biosynthesis of the lipopolysscharide core which forms a cell wall.

This study focused on UDP-Glc PPase from Escherichia coli which is encoded by both galU and galF genes. The first part of this project investigated amino acids that could play an important role in the function of UDP Glc PPase (GalU). Based …

Anti-Nogo-A Immunotherapy Facilitation Of Environmental Enrichment's Effects On Recovery From Stroke In The Aged Rat, Sarah Jane Hein

Master's Theses

Stroke and traumatic brain injury are devastating disorders that often lead to permanent neurologic deficits, with few available treatment options once injury has occurred. In previous work, Anti-Nogo-A immunotherapy has been shown to neutralize the neurite inhibitory protein, Nogo-A, and to promote neuronal plasticity and improve functional recovery after stroke in the rat. Furthermore, other reports have demonstrated that environmental enrichment improves functional recovery in rodents following stroke. Our previous work demonstrated that anti-Nogo-A immunotherapy also helps promote cortical plasticity in the rodent. In the current project, we examined two methods to promote recovery after brain injury, a stroke model …

Functional And Phenotypical Analysis Of The Effects Of Aging On B Cells And Their Bone Marrow Microenvironment, Nicole May Ziegler

Master's Theses

Aging impacts multiple organ systems, and specifically causes the immune system to lose its ability to efficiently fight off infections. Regarding immunity, aging research predominantly focuses on the adaptive immune system. B cells, which mediate the humoral arm of the adaptive immune system, develop throughout life in the bone marrow where microenvironmental `niches' are important. The bone marrow does not exactly `atrophy' with age; however, studies comparing young and old mice demonstrate an age-related change in the bone marrow B cell subpopulations.

The overall goal was to determine if femoral and sternum bone marrow have different plasma cell composition and …

A Phonetic, Phonological, And Morphosyntactic Analysis Of The Mara Language, Michelle Arden

Master's Theses

This thesis presents a linguistic analysis of the Mara language, a Tibeto-Burman language spoken in northwest Myanmar and in neighboring districts of India. Data has been gathered through interviews with a native speaker. The analysis includes a full phonetic segment inventory of the dialect and a phonological analysis of contrastive sounds and contextual variants. Sound files embedded in the document illustrate the phonetic system. Mara's distinctive phonetic features include the loss of word-final consonants, a set of voiceless sonorants, pre- and post- aspirated nasals, and lowered and unlowered vowel pairs. The morphosyntax of Mara pronominal words demonstrates a split-ergative case …

Interannual Differences In The Estuarine Ghost Shrimp, Neotrypaea Californiensis, Michael Buncic

Master's Theses

The dispersal of invertebrate marine larvae can be expected to be wide ranging and show little population structure. Neotrypaea californiensis, the burrowing ghost shrimp, is found throughout the waters and coastal estuaries of the northwestern United States. Three hundred and four larval samples were used to study population diversity and structural difference occurring over the course of spawning periods from June to September in successive years (2005 and 2006). Data and genetic analysis from nucleotide sequencing of a section of the mitochondrial Cytochrome C oxidase subunit I (COI) gene suggest that ocean-borne larvae off the coast of Oregon and Washington …

The time period surveyed in this thesis is from 1935 to 2000. The purpose was to establish any changes to reporting agricultural news over the years. A social history of agricultural journalism in the San Jose Mercury News over a 65-year period provided insight into how the farming industry was …

Western Pond Turtle Summer Habitat Use In A Coastal Watershed, Jae Abel

Master's Theses

Western pond turtle (Actinemys marmorata) habitat use was studied in a coastal pond, lagoon, and stream system during the summer of 1995 and 1996 at Waddell Creek, Santa Cruz County, California. Location and habitat association data were recorded for locations and sightings of radio-tagged and un-tagged turtles during the normal active season. Summary comparison of habitat associations and habitat availability provided inference of habitat preference at several habitat scales. For most of the active season the turtles were in relatively sunny aquatic habitat, in deeper, slower velocity water. In addition, the turtles were most commonly associated with exposed …

The Economic Impact In Stanislaus And San Joaquin Counties If A Fruit And Vegetable Processor Left As A Result Of Changes In The Food Processing Byproduce Use Program, Jessica Erin Bylsma

Master's Theses

In 1978, Stanislaus County took a proactive approach to food processing byproduct waste and established the Food Processing Byproduct Use Program. It allows processors to transport byproduct to local producers, where it serves as an alternative input. There is concern that the program negatively impacts local groundwater. The Regional Water Quality Control Board proposed that the County institute water monitoring which would increase program expenses. In response to this proposal, participants investigated the impact of the cost increase and some have concluded that this increase would preclude their continued involvement. They believe the program has allowed them to maintain their …

Automation In Cs1 With The Factoring Problem Generator, Joshua B. Parker

Master's Theses

As the field of computer science continues to grow, the number of students enrolled in related programs will grow as well. Though one-on-one tutoring is one of the more effective means of teaching, computer science instructors will have less and less time to devote to individual students. To address this growing concern, many tools that automate parts of an instructor’s job have been proposed. These tools can assist instructors in presenting concepts and grading student work, and they can help students learn to program more effectively. A growing group of intelligent tutoring systems attempts to tie all of this functionality …

Neural Replay : A Possible Mechanism For Differing Rehersal Strategies Across Parity, Cassie Brooke Jones

Master's Theses

All mammalian females undergo behavioral and neurological changes during pregnancy and motherhood. Many of these changes lead to an enhanced ability to be an effective mother including: increased memory, foraging behaviors, and boldness. Here, we examined the differences in rehearsal strategies between mother and virgin rats. Stops made by rats when exploring their environment have been found to result in reverse replay activity in the hippocampus (Foster & Wilson, 2006). Reverse replay is sequential replay that occurs in the hippocampus immediately after a spatial experience; this replay/activation is in reversed order of the initial spatial episode (Foster & Wilson, 2006). …

Techniques For Triggering Germination Of Adenostoma Fasciculatum In Revegetation Projects At Rocky Canyon Quarry, Stephanie B. Scolari

Master's Theses

Rocky Canyon Quarry is a granite mine located in the Santa Lucia Mountains about 5 miles southeast of the city of Atascadero. The Surface Mining and Reclamation Act (SMARA), which passed in 1975, dictates that California mines must rehabilitate lands disturbed by mining operations. Dr. V. L. Holland and his students in the Biological Sciences Department at California Polytechnic State University, San Luis Obispo (Cal Poly) have been working on restoration and revegetation of the Rocky Canyon Quarry since the early 1990’s.

Adenostoma fasciculatum (chamise) dominates the chaparral communities (chamisal chaparral) found in Rocky Canyon. Chamise is the most common …

Dissolved Organic Matter Influences The Timing Of Embryonic Development Of The Purple Sea Urchin, Strongylocentrotus Purpuratus., Corbin J. Hodges

Master's Theses

Marine dissolved organic matter (DOM) comprises one of the largest carbon reservoirs on earth and has long been considered a potential energy source for marine invertebrates. The importance of DOM transport has been adequately demonstrated for unicellular organisms, where DOM can meet 100% of an organisms energy needs, but the effects of DOM uptake for marine metazoans are less well understood. In this study, three general areas involving the influence of DOM transport to marine invertebrates were explored. First, we assessed the effects of using seawater exposed to high intensity ultraviolet radiation (UVR) on the study organism; embryos of the …

Arroyo Toad (Anaxyrus Californicus) Life History, Population Status, Population Threats, And Habitat Assessment Of Conditions At Fort Hunter Liggett, Monterey County, California, Jacquelyn Petrasich Hancock

Master's Theses

The arroyo toad (Anaxyrus californicus) is a federally endangered species found on Fort Hunter Liggett, Monterey County, California. The species was discovered in 1996 and was determined to occupy 26.7 km of the San Antonio River from approximately 2.4 km northwest of the San Antonio Mission de Padua, to the river delta above the San Antonio Reservoir. The construction of the San Antonio Reservoir dam in 1963 isolated this northern population of arroyo toads. Through time, the Fort Hunter Liggett landscape has changed drastically. The land was heavily grazed by cattle until 1991, which considerably reduced vegetation in riparian areas. …

A Computational Model Of Apoptotic Osteocyte Correlation To Cortical Bone Remodeling Parameters, Michael Stephen Alexander

Master's Theses

The onset of osteoporosis caused by aging, disease states, and post-menopausal conditions significantly impacts patient quality of life, required healthcare funding, personal autonomy losses from increased fracture risk and the subsequent corrective surgery. Research has indicated that osteocyte apoptosis may be a key parameter in bone remodeling, raising the possibility of remodeling rate modulation for the mitigation of bone mass resorption. By developing therapies that target osteocyte apoptosis, it may be possible to prevent undesired bone remodeling activity while maintaining a healthy balance between damage formation in the form of microcracks induced by the strain environment and the removal of …

The Effect Of Embryo Biopsy And Vitrification On The Development Potential Of Equine Embryos, Richard O. Gearhart

Master's Theses

This study investigated the development potential of equine embryos in vitro after biopsy and vitrification. Twenty embryos were obtained from Quarter Horse, Thoroughbred, and mix-breed light mares between three and ten years old. The twenty embryos were divided into a biopsy (n=10) and control group (n=10). The biopsy group underwent microaspiration biopsy using a micromanipulator to obtain a small tissue sample from the embryo. Both groups were then vitrified using a commercially available technique originally described by Carnevale (2006) at Colorado State \ University.

All 20 embryos were cultured in DMEM/Hams F-12 medium under oil at 37°C in 5% CO2 …

Changing Portrayals Of Captain James Cook In Hawaiian Education, Christopher Aaron Straub

Master's Theses

This paper covers the portrayals of Captain James Cook within Hawaiian education. It begins by providing a backdrop to early European portrayals of Captain Cook and then proceeds to investigate how these portrayals changed as they were incorporated into Hawaiian textbooks. The paper then continues to illustrate the changes made in Cook’s portrayal within Hawaiian textbooks and how these changes coincide with the prevailing interests of the eras in which the authors wrote them.
