Two Essays On Liquidity Essay I: Information Related Trading On Two Nearly Identical Options Essay Ii: The Importance Of The Liquidity Premium In The Presence Of Declining Transactions Cost, Wei-Xuan Li

LSU New Orleans Theses and Dissertations

In the first essay, I examine the impact of the introduction of exchange traded funds (ETFs) options on the information related trading of index options. Two option pairs, NASDAQ 100 index (NDX) and ETF (QQQ, currently QQQQ ) options, and Standard and Poor's 500 index (SPX) options and S & P Depository Receipts (SPY) options, are studied. I test the hypothesis, based on the theory of Chowdhry and Nanda (1991), and Admati and Pleiderer (1988), that the information component of spreads for index options should decline after ETF options were introduced. The method of George, Kaul and Nimalendran (1991) is …

Twenty-Four-Hour Woman, Mawiyah Bomani

LSU New Orleans Theses and Dissertations

"Sweet Black Pussy for Sale" sets the stage for this very feminine and colloquial laced collection of verse. Both figuratively and literally, the voices of a seldom-traveled African-American culture are depicted through these songs. In this thesis, I consider myself a GRIOT, sworn to tell nothing but the truth. These poems speak from places some might consider sacred and others quite sinful. These poems moan out the anthems of those unsung heroes and heroines from my family lineage. The voices of my long dead grandfather, grandmother, aunts and great uncle haunt poems such as "Blues," "Salvation," "A Memorial for Lawrence," …

Theses and Dissertations

Drawing from sociocultural theory, this research investigated the effects of synchronous computer-mediated communication (SCMC) in the development of writing fluency. Likewise, the study aimed at confirming previously cited affective benefits linked to SCMC. Measuring fluency in words per 30 minutes, the study compared pre and post-test essay scores of two groups of ESL learners (a control group and a SCMC group) in two intermediate levels. Two evaluation questionnaires were also administered to the SCMC group in order to obtain students' opinions of this technology-based medium, and to analyze change in their perceptions. The SCMC group outperformed the control group in …

Military Base Closure And Community Transformation: The Case Of England Air Force Base In Central Louisiana, Phyllis E. Mayo

LSU New Orleans Theses and Dissertations

Closing England Air Force Base (AFB) emerged as a possibility following the first Base Realignment and Closure (BRAC) round in 1988. The central Louisiana community responded with a dual strategy: defense, implemented by a highly visible group of mostly elected officials who fought to save the base; and offense, implemented by a small group of professionals working in the background to develop a contingency plan. Together, they managed both sides of the change equation, political and technical, and produced a military to civilian conversion. This thesis focuses on policy issues of base closure and ingredients for success and failure among …

Cooperative Jamming In Wireless Networks - Turning Attacks Into Privacy Protection, Jingqi Wu

LSU New Orleans Theses and Dissertations

Generally, collisions between packets are undesired in wireless networks. We design this scheme, Cooperative Jamming in Wireless Networks (CJWN), to make use of collision to protect secret DATA packets from being sniffed by a nearby eavesdropper. We are intending to greatly increase the Packet Error Rate (PER) at the eavesdropper when the PER at the receiver is maintained at an acceptable level. This scheme is not intended to completely take the place of various encryption/decryption schemes which are working based on successfully received packets. Adding CJWN to the popular CSMA/CA adopted in IEEE 802.11 will add more security even the …

Text Mining In Radiology Reports, Tianxia Gong, Chew Lim Tan, Tze-Yun Leong, Cheng Kiang Lee, Boon Chuan Pang, C. C. Tchoyoson Lim, Qi Tian, Suisheng Tang, Zhuo Zhang

Research Collection School Of Computing and Information Systems

Medical text mining has gained increasing interest in recent years. Radiology reports contain rich information describing radiologist's observations on the patient's medical conditions in the associated medical images. However as most reports are in free text format, the valuable information contained in those reports cannot be easily accessed and used, unless proper text mining has been applied. In this paper we propose a text mining system to extract and use the information in radiology reports. The system consists of three main modules: a medical finding extractor a report and image retriever and a text-assisted image feature extractor In evaluation, the …

Parental Hesitation As A Factor In Delayed Childhood Immunization, Karlen E. (Beth) Luthy, Renea L. Beckstrand, Neil E. Peterson

Faculty Publications

Introduction: One reason for lower immunization rates is that some parents hesitate to have their children immunized. A hesitancy questionnaire was developed to identify reasons parents hesitate in having their children immunized.

Methods: The hesitancy questionnaire was distributed from local pediatric and family practice offices and from the area's county health department. To be eligible, participants needed to be present in the clinic with a child needing a minimum of one immunization that was at least 6 months overdue.

Results: When questioned why their child was overdue for immunizations, the most common response was that participants were confused about the …

La Propiedad Inconclusa, Alfredo Bullard González

The Latin American and Caribbean Journal of Legal Studies

There's an important principle standing in the way of government takings. It's the idea of property rights, which protects against the taking of legitimately owned property. Its importance can hardly be overstated. Without it there's no incentive to make sunk investments, as they can simply be taken away. The lack of investment apparent in the developing world is partly due to the lack of legislation to protect investors' property. Property rights give people the incentive to make investments of their own labor, as well as capital investments. The problem for economists around the world is becoming how -- not whether …

Eficiencia Judicial Y Desarrollo Económico: El Caso De Los Juicios Mercantiles, Isaac Katz

The Latin American and Caribbean Journal of Legal Studies

El propósito de este ensayo es, primero, analizar la importancia para el desarrollo económico de una eficiente definición de los derechos privados de propiedad. Segundo, establecer porqué es crucial tener un Poder Judicial que sea imparcial y eficiente en sus decisiones cuando se trate de garantizar y proteger los derechos de propiedad, resaltando la importancia de que todos los procesos judiciales sean, en consecuencia, transparentes. La opacidad, la falta de transparencia, introduce un elemento de incertidumbre de que el Poder Judicial sea efectivamente imparcial, hecho que encarece la inversión productiva e inhibe, en consecuencia, el desarrollo económico.

Globalization And National Information Policy In Nigeria, Augonus Nnamdi Uhegbu

Library Philosophy and Practice (e-journal)

The paper focuses on the need for a national information policy in Nigeria in the face of globalization. The paper is not anti-globalization, but believes that although globalization facilitates global access to information and its generating media, it also has the potential of exposing Nigerians to obscene information materials, and of dumping unwholesome, improperly packaged and substandard information resources in the country. The conceptual explanation of both globalization and information policy is discussed. Also discussed is Nigeria 's contemporary information environment, which this paper sees as highly risky, volatile and uncoordinated. The paper argues that with national information policy, globalization …

The paper focuses on the role played by the Internet in academic research and highlights opportunities and challenges it presents. It explores the status of Internet connectivity in Nigeria and examines the …

The University Library, Information Provision, And Use By Policymakers In Olabisi Onabanjo University (Oou), Nigeria, Abiodun O. Odunewu

Library Philosophy and Practice (e-journal)

Availability and timely access to information is indispensable in policy formulation and implementation. It is often believed that a library is as good as its patronage. This study is an attempt to relate the level of patronage of Olabisi Onabanjo University Library by its policymakers to its information delivery capability. A questionnaire was used to gather data, with 102 copies administered at the senate level and 18 copies administered at the Governing Council level. A total of 89 copies were returned, representing an 80 percent response rate. The study reveals inadequate patronage of the library by policymakers. The study concludes …

Among the selected search engines, Hotbot had the most overlap (followed by Google) with other search engines except Bioweb. Compound and complex queries produced more overlap than simple queries.

Habitat Analysis Of North American Sand Flies Near Veterans Returning From Leishmania-Endemic War Zones, David Claborn, Penny Masuoka, Meredith Morrow, Lisa Keep

College of Health and Human Services

Background: Nearly 1300 cases of leishmaniasis have been identified in American military personnel deployed to Iraq and Afghanistan. The symptoms of this disease can range from a mild, self-limiting cutaneous infection to a deadly visceral infection and are not prevented by chemoprophylaxis or immunization. Effective treatments, however, are available. The disease-causing parasite is spread through the bite of the female sand fly. Although the disease occurs in both the Old World and the New World, the parasite species differ between the hemispheres. The large number of cases in military veterans has caused some concern that Old World, temperate-adapted parasite species …

Best Of All Possible Care: An Examination Of Scientifically Progressive Medicine In Hays From 1867 To 1918, Ben Peeler

Master's Theses or Doctor of Nursing Practice

From the mid-nineteenth century until the early decades of the twentieth century, medicine underwent a tremendous transformation. No longer was medicine to be based on archaic theories that were grounded on unquantifiable guesswork. Instead, medicine became scientifically progressive, pushing the reliability and credibility of medical professionals to new heights. Scientific progressivism was the concept of standardizing medicine around a common set of ideals, such as basing treatment upon scientifically sound methods and procedures. A scientifically progressive community can be identified through the application of one or more of the following criteria: education adaptability, and technology. These three criteria could be …

Topical Application Of Entry Inhibitors As "Virustats" To Prevent Sexual Transmission Of Hiv Infection, Michael M. Lederman, Robin L.P. Jump, Heather A. Pilch-Cooper, Scott F. Sieg

Faculty Scholarship

With the continuing march of the AIDS epidemic and little hope for an effective vaccine in the near future, work to develop a topical strategy to prevent HIV infection is increasingly important. This stated, the track record of large scale "microbicide" trials has been disappointing with nonspecific inhibitors either failing to protect women from infection or even increasing HIV acquisition. Newer strategies that target directly the elements needed for viral entry into cells have shown promise in non-human primate models of HIV transmission and as these agents have not yet been broadly introduced in regions of highest HIV prevalence, they …

Improving Library Searches Using Word-Correlation Factors And Folksonomies, Maria Soledad Pera

Theses and Dissertations

Libraries, private and public, offer valuable resources to library patrons; however, formulating library queries to retrieve relevant results can be difficult. This occurs because when using a library catalog for library searches, patrons often do not know the exact keywords to be included in a query that match the rigid subject terms (chosen by the Library of Congress) or terms in other fields of a desired library catalog record. These improperly formulated queries often translate into a high percentage of failed searches that retrieve irrelevant results or no results at all. This explains why frustrated library patrons nowadays rely on …

Resonance Raman Characterization Of The Peroxo And Hydroperoxo Intermediates In Cytochrome P450, Ilia G. Denisov, Piotr J. Mak, Thomas M. Makris, Stephen G. Sligar, James R. Kincaid

Chemistry Faculty Research and Publications

Resonance Raman (RR) studies of intermediates generated by cryoreduction of the oxyferrous complex of the D251N mutant of cytochrome P450_cam (CYP101) are reported. Owing to the fact that proton delivery to the active site is hindered in this mutant, the unprotonated peroxo-ferric intermediate is observed as the primary species after radiolytic reduction of the oxy-complex in frozen solutions at 77 K. In as much as previous EPR and ENDOR studies have shown that annealing of this species to ∼180 K results in protonation of the distal oxygen atom to form the hydroperoxo intermediate, this system has been exploited to …

"Oye Mi Voz!" (Hear My Voice!): The Perceptions Of Hispanic Boys Regarding Their Literacy Experiences, Rubylinda Zickafoose

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to uncover the perspectives that pertain to the literacy experiences of young Hispanic boys. Hispanic boys will be asked to describe, feel, judge, and make sense of their public and private literacies (Faulkner, 2005). This phenomenological study embraces two methods of data collection, participant focus groups and individual interviews. The primary question guiding this inquiry was: What are the perceptions of adolescent Hispanic boys who are considered low level readers (by state achievement tests) regarding their literacy experiences?

In order to help provide background information and set the stage for future work when considering …

Learning From Near Misses In Medication Errors: A Bayesian Approach, Jessica A. Myers, Francesca Dominici, Laura Morlock

Johns Hopkins University, Dept. of Biostatistics Working Papers

Medical errors originating in health care facilities are a significant source of preventable morbidity, mortality, and healthcare costs. Voluntary error report systems that collect information on the causes and contributing factors of medi- cal errors regardless of the resulting harm may be useful for developing effective harm prevention strategies. Some patient safety experts question the utility of data from errors that did not lead to harm to the patient, also called near misses. A near miss (a.k.a. close call) is an unplanned event that did not result in injury to the patient. Only a fortunate break in the chain of …
