Description

The Center for Engaged Learning and Teaching Research Showcase collection features the individual research projects and supplemental materials produced by CELT Fellows, Tulane students and faculty-mentors. This project documents research projects from between the years 2015 through 2017. The collection will grow to include new projects in future years to come. Research areas highlighted in this collection include the sciences and the humanities as well as inter-disciplinary projects.

CELT collection materials consists of posters, photos, extended abstracts, papers, and data collected from CELT-funded research projects. All of the individuals who participated in submitting work and supplemental materials have agreed to have their materials hosted online, through social media, and through the Library Web site as an exhibition.

3D Printing of Patterned Surfaces Using Functionalized Silicon Nanoparticles
1-7 Octadiene and 1-Hexyne functionalized Silicon Nanoparticles synthesized via Reactive High Energy Ball Milling (RHEBM) were printed on glass and plastic substrates using material inkjet printing to determine optimal parameters. Material inkjet printing is important for industrial scale roll to roll processing of flexible circuits for electronic devices. Page 27 of the CELT Research Abstract Booklet., celt@tulane.edu
Bacterial Swimming and Biofilms Porous Media Affected with Entrapped by Oil Spills
Studies have shown that many bacteria isolated from crude oil contaminated sites can use crude oil as their carbon source, making these microbes favorable crude oil degraders. Due to the wide range of isolated strains, there are a variety of strains to choose from to create an effective bacteria consortium. Page 19 of the CELT Research Abstract Booklet., celt@tulane.edu
Behavioral barriers in the speciation process: color variation in a hybrid zone of role-reversed species
Species-specific"nvocalizations can be reproductive isolating mechanisms among closely related populations. We analyze vocal divergence between two hybridizing species of shorebirds, the Northern Jacana (Jacana spinosa) and Wattled Jacana (Jacana jacana). As these species are both sexually dimorphic, we also compare calls between males and females. Page 20 of the CELT Research Abstract Booklet., celt@tulane.edu
Biochemical Mechanism of TU-1, a New Antibiotic Drug
The advent of modern medicine in the 19th and 20th centuries drastically improved the knowledge, detection, and treatment of infectious diseases caused by bacteria. Unfortunately, the wide spread overuse and misuse of antibiotics has selected for a growing number of bacterial strains that have developed resistance to a wide range of therapeutic drugs.

Chagas Disease in New Orleans: An Opportunity for Student and Community Training
Trypanosoma cruzi is a pathogenic microorganism that cause Chagas disease, an anthropozoonosis that represents a major public health problem in Latin America. T. cruzi is widely distributed throughout the American continent, from the southern regions of the United States (U.S.) to Argentina, and infects at least 6 million people in Latin America.

Composition for Surround Sound
Though creating an array of speakers, the ability to generate and manipulate spatialized sound becomes possible. Surround sound enables more tools for expression and emphasis than just pitches and dynamics by giving it a perceivable location. Page 31 of the CELT Research Abstract Booklet., celt@tulane.edu
Development of Adjuvant HIFU Therapy for Prostate Cancer
High-intensity focused ultrasound (HIFU) emerges as a powerful technology for noninvasive or minimally invasive non-ionizing treatment of cancer, with recent FDA approval. HIFU deposits a large amount of acoustic energy at the focal region within the target tissue (i.e., tumor), causing tissue heating and necrosis.

The Development of Face Maps during the First Year
Individuals possess functional maps of the body that enable them to use their hands to localize targets positioned on the skin. These functional maps have great adaptive value. They enable individuals to engage in self-feeding and remove stimuli from the body, and they may also contribute to a sense of self (Amsterdam, 1972).

Economic and Environmental Impacts of Globalization on Women in the Developing World
The "u201crace-to-the-bottom"u201d theory of globalization argues that the highly-mobile nature of capital in the modern global political-economy incentivizes corporations moving their operations to those nations with the least environmental regulations (Wheeler 2001). This suggests a positive correlation between foreign direct investment (FDI) and environmental degradation, a hypothesis which has been widely studied and supported by quantitative analyses (McKinney 2014).

Employment Discrimination against Indigenous People and the Labor Market Impact of Indian Reservations: Evidence from a Field Experiment
The history of Indigenous Peoples in the United States is marred by forced removal, racism, illness, and ultimately genocide. Today, indigenous peoples continue to face challenges, specifically in terms of economics as American Indian and Alaskan Native (AIAN) peoples face high levels of unemployment at 9.9% and Native Hawaiians and Other Pacific Islander (NHPI) peoples experience an unemployment rate of 5.7% in comparison to white people"'s unemployment rate of 4.6%.

Expression of Cation-Chloride Transporters in Vasopressin and Oxytocin Neurons in the Rodent Brain
GABA, a typically inhibitory neurotransmitter, can act in an excitatory manner when the reversal potential (EGABA) becomes positive compared to the resting membrane potential. Page 4 of the CELT Research Abstract Booklet., celt@tulane.edu
Fighting against Crime: How Citizen Participation and Collective Action Deter Crime in New Orleans
Police departments across the country are extremely motivated to find procedures that can deter and reduce crime at a low cost. Previous studies in economics and criminology have concluded that significant police visibility and proactive patrolling strategies in crime "u201chot spots"u201d can effectively deter crime. This paper investigates the impact of citizen participation and collective action has to further reduce crime in "u201chot spots"u201d in New Orleans, specifically the French Quarter.

In Vivo Alabation of Liver Cancer by High-Intensity Focused Ultrasound and Ethanol
The aim of this experiment was to grow tumor xenograft models in vivo and measure the effectiveness of treatment with High Intensity Focused Ultrasound (HIFU) alone and in combination with Ethanol. Page 10 of the CELT Research Abstract Booklet.
Interleukin (IL)-18 in the Differentiation and Maturation of Mast Cells and Its Implication in Mast-Cell Mediated Pathology
Recent studies have demonstrated a variety of roles for interleukin (IL)-18 in cytokine regulation and lymphocyte development, with results indicating roles in the development of both Th1 and Th2 responses depending on the other cytokines present. There is significant correlational evidence linking increased levels of IL-18 with allergic diseases in both human and animal models. Page 29 of the CELT Research Abstract Booklet., celt@tulane.edu
Laser Assisted Control of the Metal-Insulator Transition in Hydrogenated Vanadium Dioxide Nanobeams
Vanadium dioxide (VO¬2) is an incredibly promising material with many unique characteristics for electronic and optical applications. One of the defining traits exhibited by VO¬2 is the reversible metal-insulator transition (MIT). When heated up to 68°C, VO2 switches from insulating to metallic phase by showing 3 orders of magnitude increase in electrical conductance, accompanied with a crystal structural change from monoclinic to rutile in a time scale of femtoseconds.

Liberalism in Illiberal States, Trends on Political and Electoral Support for Anti-Systemic Parties in France, Germany, and Britain
I have been assisting Mark Vail in two separate projects. The first involves assisting Dr. Vail with the completion of his most recent book manuscript, currently under review at Oxford University Press with a tentative publication date of late 2017.

Magneto-optical Kerr effect magnetometry of 2D atomically-thin magnetic materials
The Magneto-optic Kerr Effect (MOKE) is the altering of polarization of light when reflected off a material within a magnetic field. MOKE is typically used to discover magnetic and optical properties of materials, which are important to know for applications of spin electronic devices. Measuring MOKE is a very sensitive process since the strong magnetic field in the system can create unwanted artifacts in our results. Page 14 of the CELT Research Abstract Booklet., celt@tulane.edu
