Women Rule, But Do They Make A Difference? Women In Politics, Social Policy And Social Conditions In Latin America, Erika Del Pilar Burton May 2014

Women Rule, But Do They Make A Difference? Women In Politics, Social Policy And Social Conditions In Latin America, Erika Del Pilar Burton

LSU New Orleans Theses and Dissertations

Since the transitions to democracy in Latin America, women in the region have undergone major changes in their roles in society. From traditionally only present in the home to participating in collective action efforts, and finally participating at increasing numbers in governments, women have made incredible strides in the Latin American region. Latin American countries have successfully advocated for the inclusion of women in government, but few studies in academia focus on determining whether their inclusion has made a difference in government processes or in society. Borrowing from the literature positing that women are behaviorally different from men as well …

Synthetic Triterpenoid Induces 15-Pgdh Expression And Suppresses Inflammation-Driven Colon Carcinogenesis, Sung Hee Choi, Byung-Gyu Kim, Janet Robinson, Steve Fink, Min Yan, Michael B. Sporn, Sanford D. Markowitz, John J. Letterio

Dartmouth Scholarship

Colitis-associated colon cancer (CAC) develops as a result of inflammation-induced epithelial transformation, which occurs in response to inflammatory cytokine-dependent downregulation of 15-hydroxyprostaglandin dehydrogenase (15-PGDH) and subsequent suppression of prostaglandin metabolism. Agents that both enhance 15-PGDH expression and suppress cyclooxygenase-2 (COX-2) production may more effectively prevent CAC. Synthetic triterpenoids are a class of small molecules that suppress COX-2 as well as inflammatory cytokine signaling. Here, we found that administration of the synthetic triterpenoid 2-cyano-3,12-dioxooleana-1,9(11)-dien-C28-methyl ester (CDDO-Me) suppresses CAC in mice. In a spontaneous, inflammation-driven intestinal neoplasia model, deletion of Smad4 specifically in T cells led to progressive production of inflammatory cytokines, …

Expedition, Evan M. Crankshaw May 2014

Expedition, Evan M. Crankshaw

Graduate School of Art Theses

Exoticism presents fantasy constructs of Otherness which make up a discourse of problematic “truths.” This discourse is reflected and perpetuated in culture-items (art, literature, music, etc.) which can be identified as “exotica.” On one level, exotica simply reinforces these “truths,” but it also offers potential revelations relating to the exotic construct itself, a collection of fictions so elaborate and vast that it may be said to have its own history. Exotica can be described as the reflexive form of that alternate history; it is also a fantasy zone which reveals a desire on the part of the exoticizer to escape …

Community Structures In Bipartite Networks: A Dual-Projection Approach, David Melamed May 2014

Community Structures In Bipartite Networks: A Dual-Projection Approach, David Melamed

Faculty Publications

Identifying communities or clusters in networked systems has received much attention across the physical and social sciences. Most of this work focuses on single layer or one-mode networks, including social networks between people or hyperlinks between websites. Multilayer or multi-mode networks, such as affiliation networks linking people to organizations, receive much less attention in this literature. Common strategies for discovering the community structure of multi-mode networks identify the communities of each mode simultaneously. Here I show that this combined approach is ineffective at discovering community structures when there are an unequal number of communities between the modes of a multi-mode …

Astroglial Boundary Formation And Epha4 Signaling In Neuroblast Migration, Nicholas B. Gallo May 2014

Astroglial Boundary Formation And Epha4 Signaling In Neuroblast Migration, Nicholas B. Gallo

Honors Scholar Theses

Adult neurogenesis, the process of generating new neurons from neural precursors, is a highly complex process that is limited to two specific areas of the brain, the dentate gyrus of the hippocampus and the subventricular zone (SVZ). Despite continued research investigating neurogenesis in these two regions, we still lack a fundamental understanding of the molecular mechanisms of neural cell division, migration, differentiation, and integration in the postnatal brain. In particular, the rostral migratory stream (RMS), which is a cellular migratory route for newly generated neuronal precursors that travel from the SVZ to the olfactory bulb, will provide a useful model …

Use Of Coastal Islands By Seabirds: A Tool To Guide Future Marine Protected Areas In California, Dana A. Page May 2014

Use Of Coastal Islands By Seabirds: A Tool To Guide Future Marine Protected Areas In California, Dana A. Page

Master's Projects and Capstones

Seabird breeding colonies on islands off the coast of California offer a unique tool to help guide marine spatial planning. The life histories of seabirds can be used to develop locations of ecological importance along the coast of California. Tracking methodologies and habitat modeling related to seabird habitat utilization can be used to inform management approaches which can aid in the expansion of marine protected areas (MPAs). Protecting ocean habitats will help mitigate impacts of climate change and ensure the ecosystem services provided by marine environments. Areas within the Monterey Bay National Marine Sanctuary were analyzed to locate candidate MPA …

"Dangerous Subjects": James D. Saules And The Enforcement Of The Color Line In Oregon, Kenneth Robert Coleman May 2014

"Dangerous Subjects": James D. Saules And The Enforcement Of The Color Line In Oregon, Kenneth Robert Coleman

Dissertations and Theses

In June of 1844, James D. Saules, a black sailor turned farmer living in Oregon's Willamette Valley, was arrested and convicted for allegedly inciting Indians to violence against a settler named Charles E. Pickett. Three years earlier, Saules had deserted the United States Exploring Expedition, married a Chinookan woman, and started a freight business on the Columbia River. Less than two months following Saules' arrest, Oregon's Provisional Government passed its infamous "Lash Law," banning the immigration of free black people to the region. While the government repealed the law in 1845, Oregon passed a territorial black exclusion law in 1849 …

Comparative Biology Of Three Species Of Costa Rican Haeterini, Laura Alexander May 2014

Comparative Biology Of Three Species Of Costa Rican Haeterini, Laura Alexander

LSU New Orleans Theses and Dissertations

Documenting life history characteristics of populations, especially of herbivorous insects such as butterflies, is fundamental to the ecological study of tropical rainforests. However, we know relatively little about tropical forest butterflies. Here, I combine information gathered using the mark-release-recapture (MRR) approach with manipulative and observational experiments in a natural environment to explore aspects of the population biology of three closely-related species of Costa Rican fruit-feeding understory butterflies (Cithaerias pireta, Dulcedo polita, and Pierella helvina), specifically: vertical stratification, attraction to and persistence in fruit-baited traps, relative abundance and distribution, movement patterns, probabilities of recapture and daily survival, …

Learning Together: A Case Study Of A Cooperative School’S Approach To Education, Ariana M. Ali May 2014

Learning Together: A Case Study Of A Cooperative School’S Approach To Education, Ariana M. Ali

Master's Theses

This thesis is based on an in-depth case study of one cooperative pre-preschool and preschool in San Francisco. Qualitative research methods, such as observation and one-on-one interviews, were used to study the structure, culture, and community at the school. Cooperative schools have not been well researched or documented in academic literature and this study hoped to shed some light on this model of school organization. The parent-initiated and community-oriented nature of cooperative schools make them stand out as unique among the large, bureaucratically-run schools and daycares typically found in the United States. The results of this study highlighted four themes …

Glass Foundation Chemosensor Synthesis And Functionality Analysis, Justin D. Dancer May 2014

Glass Foundation Chemosensor Synthesis And Functionality Analysis, Justin D. Dancer

Master's Theses

Chemosensors are created through a series of reaction steps on controlled pore class (CPG) and terminate with a Cu2+ metal binding site. Each monolayer of reactant insures that the metal binding site exposed to solution would serve as an indicator displacement assay (IDA) sensor. The purpose of this research is to create a molecular sensor with a high density of terminal metal sites to quantify bidentate substrates. To accomplish this, each synthetic step of the sensor is examined in order to test the effects of new linkers, ligands, and variously sized dendrimers to see if small structural changes could …

Cu (Ii) Catalyzed Gateways In The Synthesis Of Acridine Derivatives And Their Biological Evaluation As Anti-Cancer Drugs, Rajesh Komati

LSU New Orleans Theses and Dissertations

Telomeres are nucleoprotein complexes found at the ends of linear eukaryotic chromosomes. Telomeres consist of a short sequence of repetitive double stranded DNA, TTAGGG repeats in humans (and all mammals), and a complex of 6 proteins, termed the shelterin complex. The length of the telomeres varies greatly between species, from approximately 300 base pairs in yeast to many 10-15 kilo bases in humans, because of the end replication problem this length get shorten with each cell division and ultimately leads to cell death. However the immortal eukaryotic cells and some transformed human cells over come this incomplete end replication problem …

Characterization Of Dredged Sediment Used In Coastal Restoration And Marsh Creation Projects, Gregory A. Mattson Ii May 2014

Characterization Of Dredged Sediment Used In Coastal Restoration And Marsh Creation Projects, Gregory A. Mattson Ii

LSU New Orleans Theses and Dissertations

To minimize coastal land loss and create new land, dredged sediment has been in use in coastal Louisiana during the last several years. Engineering properties and material characteristics of dredged material are input parameters in several mathematical models used to predict the long-term hydrodynamic behavior of the coast. Therefore, proper characterization of the dredged material is of utmost importance in the correct design of coastal restoration and land creation projects. The sedimentation characteristics of the dredged material, among other factors, depends on the (a) grain size distribution of the dredged material, (b) salinity (fresh, brackish, or saltwater environment) of the …

A Comparison Of Concept Maps And Text Summaries: The Effects Of Study Format On Memory, Kenneth James Barideaux Jr. May 2014

A Comparison Of Concept Maps And Text Summaries: The Effects Of Study Format On Memory, Kenneth James Barideaux Jr.

Electronic Theses and Dissertations Archive

A large body of research has provided evidence that concept maps offer a greater benefit for learning compared to traditional text (e.g., Nesbit & Adesope, 2006). Reder and Anderson (1980) compared text summaries to full-length texts and found text summaries to be more beneficial for learning, suggesting that details and elaborations can hurt retention. The current research compared concept maps and text summaries in two experiments. In Experiment 1, participants studied a science topic from a concept map or text summary. Immediately following study, all participants completed a concept map posttest and text summary posttest where the arrangement of both …

Arthropod Abundance And Diversity In Restored Longleaf Pine Savannas At Abita Creek Flatwoods Preserve, Cara B. Nighohossian May 2014

Arthropod Abundance And Diversity In Restored Longleaf Pine Savannas At Abita Creek Flatwoods Preserve, Cara B. Nighohossian

LSU New Orleans Theses and Dissertations

The objective of this study is to determine whether changes in arthropod community structure in restored longleaf pine savannas corresponds to differences in vegetation structure often associated with burn frequency. Longleaf pine savannas are fire-maintained ecosystems characteristic of the southeastern United States and have experienced severe declines (around 97%) since European settlement. Changes in fire regime have been instrumental in the declines. Restoration of these ecosystems has involved reinstitution of periodic burnings to promote and maintain vegetative characteristics of the savannas. This study investigates trends in arthropod communities from areas heavily invaded by hardwood shrubs against those dominated by longleaf …

X-Ray Structure Analysis And Topological Charge Density Studies Of Gossypol Derivatives, Carlos Zelaya May 2014

X-Ray Structure Analysis And Topological Charge Density Studies Of Gossypol Derivatives, Carlos Zelaya

LSU New Orleans Theses and Dissertations

Gossypol and gossypol derivatives are natural byproducts of a variety of cotton plant species that poses interesting chemical, biological, and medicinal properties that are currently heavily researched. Supporting evidence suggest that gossypol and gossypol derivatives act on the Bcl-2 proteins that have been linked to certain cancers. Gossypol amine derivatives, specifically, are actively researched and a variety of amine derivatives have already been synthesized. However, gossypol and its derivatives are challenging compounds to work with because many of its derivatives tend to exist in various tautomeric forms. When analyzing gossypol and its derivatives it is the complex electron configuration that …

Finding Cathartic Beauty In Trauma And Abjection, Christy R. Kirk May 2014

Finding Cathartic Beauty In Trauma And Abjection, Christy R. Kirk

Graduate School of Art Theses

Inspired by the dichotomy of beauty and the grotesque in relation to the female body, I set out to both find a balance and interrupt the balance between the two with my artistic practice. Defining beauty as something more significant and meaningful than a pretty image and the abject as something that inspires repulsion, I sought to find connection between the two. Through creating abject textures surrounding nude female forms, I discovered an underlying trauma latent in the artistic expressions of my work. The process of creating abject works of art has lead to catharsis and posttraumatic growth in my …

Structural Features Of The Pseudomonas Fluorescens Biofilm Adhesin Lapa Required For Lapg-Dependent Cleavage, Biofilm Formation, And Cell Surface Localization, Chelsea D. Boyd, T. Jarrod Smith, Sofiane El-Kirat-Chatel, Peter D. Newell, Yves F. Dufrêne, George A. O'Toole May 2014

Structural Features Of The Pseudomonas Fluorescens Biofilm Adhesin Lapa Required For Lapg-Dependent Cleavage, Biofilm Formation, And Cell Surface Localization, Chelsea D. Boyd, T. Jarrod Smith, Sofiane El-Kirat-Chatel, Peter D. Newell, Yves F. Dufrêne, George A. O'Toole

Dartmouth Scholarship

The localization of the LapA protein to the cell surface is a key step required by Pseudomonas fluorescens Pf0-1 to irreversibly attach to a surface and form a biofilm. LapA is a member of a diverse family of predicted bacterial adhesins, and although lacking a high degree of sequence similarity, family members do share common predicted domains. Here, using mutational analysis, we determine the significance of each domain feature of LapA in relation to its export and localization to the cell surface and function in biofilm formation. Our previous work showed that the N terminus of LapA is required for …

Kinematic Analysis Of Prey Capture In Coastal Giant Salamanders (Dicamptodon Tenebrosus), Laura Westervelt, David Reavill, Sara Richbourg, Brandon Fessler May 2014

Kinematic Analysis Of Prey Capture In Coastal Giant Salamanders (Dicamptodon Tenebrosus), Laura Westervelt, David Reavill, Sara Richbourg, Brandon Fessler

Symposium Of University Research and Creative Expression (SOURCE)

Salamanders use a variety of techniques to capture prey that involves a combination of lingual and jaw prehension. For example, some plethodontid salamanders often use ballistic tongue projection to capture prey. Salamanders of the family Dicamptodontidae, are the largest sized terrestrial salamanders in the world which feed on a diverse array of prey items (arthropods, annelids, small mammals, and reptiles). Objectives of our study were to describe and quantify the behavior of terrestrial adult coastal giant salamanders (D. tenebrosus). While there has been much research conducted on aquatic phase D. tenebrosus, little is known about their terrestrial counterparts. Feeding bouts …

Perceived Discrimination, Ethnic Identity Development, And Well-Being In Children: An Exploration Study, Billie S. Schwartz May 2014

Perceived Discrimination, Ethnic Identity Development, And Well-Being In Children: An Exploration Study, Billie S. Schwartz

Open Access Dissertations

As diversity increases in the U.S., there is a pressing need to understand ethnic identity development in children, particularly in relation to psychological well-being. Previous studies document the importance of ethnic identity development and its influence on positive development, psychological well-being, and academic adjustment in children, particularly from ethnically diverse backgrounds (Booker; 2006; Phinney, 1990, 1995; Thomson & Zand, 2005). However, limited research investigates the relationship between ethnic identity and the well-being of school-aged children, particularly during middle childhood (García Coll & Marks, 2009; Phinney, 1990). This exploratory study sought provide greater understanding of ethnic identity development in children, as …

Murine Neonates Infected With Yersinia Enterocolitica Develop Rapid And Robust Pro-Inflammatory Responses In The Intestinal Lymphoid Tissues, David Travis Siefker May 2014

Murine Neonates Infected With Yersinia Enterocolitica Develop Rapid And Robust Pro-Inflammatory Responses In The Intestinal Lymphoid Tissues, David Travis Siefker

Open Access Dissertations

It is becoming increasingly apparent that neonates are not immune-compromised, but rather immune-variant. We have described a neonatal model of Yersinia enterocolitica infection in which protective inflammation occurs at the level of the mesenteric lymph nodes (MLN). The expression of pro-inflammatory, but not anti-inflammatory, cytokine genes was markedly induced in the neonatal MLN early after infection. Strikingly, the expression levels in neonates greatly exceeded those seen in infected adults. Elevated pro-inflammatory gene expression was quickly followed by enhanced innate phagocyte recruitment to the MLN of neonates, compared to adults. Neither CD4+ nor B cells were required for inflammation in the …
