An Underwater Channel Model And Chirp Slope Keying Modulation Scheme Performance, Brice Zoh
An Underwater Channel Model And Chirp Slope Keying Modulation Scheme Performance, Brice Zoh
LSU New Orleans Theses and Dissertations
Chirp-Slope Keying (CSK) is a new and innovative digital modulation scheme for underwater data transmission. The underwater environment brings up several challenges to the manufacturing and operation of communication systems. This thesis shows through analysis and simulations the effectiveness of Chirp-Slope Keying (CSK) in providing a satisfying performance in underwater communication. The experiment consists of modulating a chirp slope by binary numbers (representing our data). '0' is represented by a linear- down chirp and '1' is represented by a linear-up chirp. The received data is first processed by a correlator receiver. Then, the detection of either binary symbol is obtained …

In The Middle, Nicole Pugh
LSU New Orleans Theses and Dissertations
A woman just getting settled in New Orleans with her fiancé is uprooted by Hurricane Katrina. She spends the two months after the hurricane in various parts of Louisiana trying to pick up the pieces of her uprooted reality. Along the way, she encounters ordinary people who act as inspirations and is also reminded of her deceased Chinese grandmother, whom she was care-giver to before she died and whose stories about life in China and the US parallel the woman´s own life during the post-Katrina months of vulnerability and change.
The Petrochemical Industrial Complex Of The St. Charles Parish Industrial Corridor And Its Influence On Urbanization Patterns, Darin Acosta
The Petrochemical Industrial Complex Of The St. Charles Parish Industrial Corridor And Its Influence On Urbanization Patterns, Darin Acosta
LSU New Orleans Theses and Dissertations
This thesis explores the impact that the petrochemical industry has had on the built environment of Norco, St. Charles Parish, Louisiana. Previous scholars have suggested that heavy industry in Norco consumes a majority of the Mississippi River's natural levee, which is the most elevated and flood resistant land in the town. In order to test these observations, the author of this thesis has collected parcel-level land use data in Norco to determine the flood hazard and topographical characteristics of these various land uses. Spatial calculations, run using Geographic Information System software, have determined that heavy industrial land uses in Norco …
An Examination Of Faculty Satisfaction At Two-Year Higher Education Institutions, Nancy Kinchen
An Examination Of Faculty Satisfaction At Two-Year Higher Education Institutions, Nancy Kinchen
LSU New Orleans Theses and Dissertations
Part-time faculty members represent the majority of faculty at public two-year postsecondary institutions. Utilizing part-time faculty enables two-year institutions to control their instructional costs and maintain scheduling flexibility. However, part-time faculty are diverse in regards to their employment preference, some prefer part-time employment while others would prefer a full-time position. Since retaining and attracting qualified and experienced part-time faculty members is essential, it is imperative that their satisfaction be understood. This study uses the 2004 National Study of Postsecondary Faculty (NSOPF: 04) to study faculty satisfaction. Faculty was disaggregated according to employment preference into full-time, involuntary part-time, and voluntary part-time …
Resilience Characteristics Of Master's-Level Counseling Students, J. Raul Machuca
Resilience Characteristics Of Master's-Level Counseling Students, J. Raul Machuca
LSU New Orleans Theses and Dissertations
Resilience characteristics typically have been studied among children and adolescents. A new line of research on resilience is focused on exploring the resilience characteristics of adults exposed to short and long-term adversity. In the present study, 585 master's-level counseling students responded to the Resilience Scale (Wagnild & Young, 1993). The purpose of this study was to examine the relationship between counseling students' level of resilience and specific background variables (age, gender, marital status, ethnicity, education, income, employment, living situation, sexual orientation, and country of origin), counselor-education program variables (primary field of study, number of credits taken, academic status, professional affiliations, …

The purpose of this study was to determine the existence of a glass ceiling effect within community colleges by examining faculty, staff and administrator's perceptions of a glass ceiling as it relates to the advancement of women at their institutions. This was done by using a cross-sectional survey administered electronically to faculty, staff and administrators in community colleges in the United States who were members of the American Association of Community Colleges. Four hundred fifty seven participants provided responses for the study. Results of ANOVA of perceptions of facilitators and barriers to advancement revealed there was a significant difference in …
Assessing The Psychosocial Needs Of Individuals Diagnosed With Cancer, By Age And Sex On Interest In Support Group Attendance, Mary Rodrigue
Assessing The Psychosocial Needs Of Individuals Diagnosed With Cancer, By Age And Sex On Interest In Support Group Attendance, Mary Rodrigue
LSU New Orleans Theses and Dissertations
There are several psychosocial factors that can affect an individual diagnosed with cancer (Holland, 2003), and directly addressing these issues with patients is important for their overall care and quality of life (Holland, 1998). The practice of psycho-oncology has been designed to assess these psychosocial issues with patients and their caregivers by means of outlets such as support groups to facilitate a wellness model of care (Myers & Sweeney, 2008). Using the demographics of age and sex, I plan to analyze and identify what psychosocial needs are significant to individuals diagnosed with cancer, and compare the sex and age of …
Retention And Graduation Rates As Performance Indicators In 2-Year And 4-Year Postsecondary Institutions, Lisa Watson
Retention And Graduation Rates As Performance Indicators In 2-Year And 4-Year Postsecondary Institutions, Lisa Watson
LSU New Orleans Theses and Dissertations
The focus of this dissertation is on performance indicators – specifically, retention and graduation indicators - that impact allocation of the ever-dwindling public sources of money. Decreasing revenue trends make understanding the performance indicators that are often used to fund postsecondary institutions very important. There is a significant amount of literature on funding, types of funding, and performance indicators used in funding; however, there is very little literature on quantitative differences on standard performance indicators in 2-year and 4- year postsecondary institutions. The purpose of this study is to look at retention and graduation rates for part-time and full-time students …
Prey Selection By Young Lemon Sharks (Negaprion Brevirostris) At Chandeleur Island Nursery Habitats With A Comparison To Three Other Co-Occurring Shark Species, Christopher Davis
Prey Selection By Young Lemon Sharks (Negaprion Brevirostris) At Chandeleur Island Nursery Habitats With A Comparison To Three Other Co-Occurring Shark Species, Christopher Davis
LSU New Orleans Theses and Dissertations
The Chandeleur Islands (Louisiana) contain nursery habitats for lemon sharks that provide abundant prey and protection from predation. Other local shark species (Atlantic sharpnose, bull, and blacktip sharks) co-occur with lemon sharks in the same region, including the nearby Biloxi Marshes. To better assess how lemon sharks use these nursery habitats, I measured diet and prey availability of young of the year and juvenile lemon sharks from 2009 to 2010. Young lemon sharks at the Chandeleur Islands have a relatively reduced diet breadth in comparison to those from nurseries in Bimini (Bahamas) and the Florida Keys. At the Chandeleur Islands, …

The Facets Of Hostile Attributional Bias: The Importance Of Aggression Subtypes And Provocateur Motivation, Melissa Kunimatsu
The Facets Of Hostile Attributional Bias: The Importance Of Aggression Subtypes And Provocateur Motivation, Melissa Kunimatsu
LSU New Orleans Theses and Dissertations
The current study examined the association of hostile attributional bias (HAB) with the functions (proactive and reactive) and subtypes (reactive relational and reactive overt) of aggression as well as with perceived provocateur motivation (proactive or reactive) in a high school sample (mean age = 16.51; 50% male; 31% Caucasian). Revisions to a measure of HAB were made both in administration (adding animations/narration) and content (adding perceived provocateur motivation questions). Results indicated that the animation/narration measure showed comparable internal consistency reliability to the written and displayed an increased ability to predict total aggression. However, a unique relationship between HAB and reactive …
Toward A Database Of Geometric Interrelationships Of Protein Secondary Structure Elements For De Novo Protein Design, Prediction And Analysis, Augustine Ada Orgah
Toward A Database Of Geometric Interrelationships Of Protein Secondary Structure Elements For De Novo Protein Design, Prediction And Analysis, Augustine Ada Orgah
LSU New Orleans Theses and Dissertations
Computational methods of analyzing, simulating, and modeling proteins are essential towards understanding protein structure and its interactions. Computational methods are easier as not all protein structures can be determined experimentally due to the inherent difficultly of working with some proteins. In order to predict, design, analyze, simulate or model a protein, data from experimentally determined proteins such as those located in the repository of the Protein Data Bank (PDB) are essential. The assumption here is that we can use pieces of known proteins to piece together a "new" protein hence, de novo protein design. The analysis of the geometric relationships …
Essay On The Persistence Of Corporate Diversification Discount After Merger And Acquisition Transactions And Essay On The Capital Structure Properties Of Real Estate Investment Trusts (Reits), Yasser Alhenawi
LSU New Orleans Theses and Dissertations
In the first chapter of this dissertation, I hypothesize that several non-tax-driven benefits of debt induce REITs managers to issue debt despite no apparent tax-driven benefit. Several methodologies and tests applied in capital structure literature are introduced to the literature of REITs capital structure. First, I investigate how the market prices leverage in absence of tax-deductibility benefit. Then, I diagnose the relative importance of several non-tax-driven benefits of leverage in deriving the capital structure decisions of REITs. Third, I conduct a thought investment experiment with debt-restricted vs. non-restricted REITs portfolios. I find weak evidence that leverage, by itself, creates value. …

Multivariate Cluster Analysis Of The Mmpi-2 And Mmpi-2-Rf Scales In Spine Pain Patients With Financial Compensation: Characterization And Validation Of Chronic Pain Subgroups, Luis Aguerrevere
LSU New Orleans Theses and Dissertations
Different psychosocial factors influence the experience and adaptation to pain. Previous cluster analytic studies using the Minnesota Multiphasic Personality Inventory-2nd edition described psychologically different subgroups of pain patients that had been shown valuable in determining outcome. However, these studies had limited applicability to medico-legal pain populations because they did not use newly developed scales or describe important medico-legal factors that have large effects on symptom endorsement. Using three methods of clustering, the current investigation explored the subgroups that resulted when using all the MMPI-2 and the newly developed MMPI-2-RF (Restructured Form) scales on a large and well-described population of medico-legal …
The Relationship Between Professional Identity And Collective Self- Esteem In School Counselors, Susan Foster
The Relationship Between Professional Identity And Collective Self- Esteem In School Counselors, Susan Foster
LSU New Orleans Theses and Dissertations
All bona fide professions have affiliated professional organizations, ethical standards or a code of ethics, and an accrediting and sanctioning body that deals with preparation, credentialing, and licensure, and pride in one's profession (Gale & Austin, 2003; Remley & Herlihy, 2010). As school counseling continues to evolve, school counselors have struggled to define and maintain their role. This may be due, in part, to the social desirability an individual has to belong to dominant group in the school setting (Tajfel, 1986). School counselors may draw esteem from their professional membership. This concept, called collective self-esteem, denotes those aspects of identity …

Accurate rainfall forecasting using weather radar imagery has always been a crucial and predominant task in the field of meteorology [1], [2], [3] and [4]. Competitive Radial Basis Function Neural Networks (CRBFNN) [5] is one of the methods used for weather radar image based forecasting. Recently, an alternative CRBFNN based approach [6] was introduced to model the precipitation events. The difference between the techniques presented in [5] and [6] is in the approach used to model the rainfall image. Overall, it was shown that the modified CRBFNN approach [6] is more computationally efficient compared to the CRBFNN approach [5]. However, …
God Of Our Fathers: Catholic Chaplains In The Confederate Armies, Gary W. Mccall
God Of Our Fathers: Catholic Chaplains In The Confederate Armies, Gary W. Mccall
LSU New Orleans Theses and Dissertations
The Civil War contained many examples of courage and commitment to duty that were inspired by religion. In recent years much has been written on this subject of religion and the Civil War but virtually all of it is written about Protestant chaplains and this has created a gap in the record. This thesis covers the role played by Catholic chaplains in Confederate army regiments from Louisiana. It explores their life, ministry, military role, and impact on the regiments. To cover this in depth the Catholic chaplains selected we those who left published records.

Left To My Own Devices, Charisse Celino
LSU New Orleans Theses and Dissertations
I compose work from what may be considered debris. There is a history contained within these items that I want to redefine. Materials dictate and inform the direction of my work. The search and discovery of these objects is intuitive. Acquiring the piece(s) ties into my inspiration of its possible new function. My objective is to encourage others to notice the everyday and see the aesthetic value of these objects. Often they are organized into a grid. Whether taking an individual object or making multiples into a single image, I am altering the function of these items, reordering them and …
Configuration Of The Pleistocene Surface Beneath Cat Island, Mississippi And Implications For Barrier Island Formation And Evolution, Kathryn Rose
LSU New Orleans Theses and Dissertations
The mechanism of Holocene barrier formation aids in determining island geomorphologic responses to modifying climatic processes of the surrounding environment. The geometry and composition of local antecedent topography plays a role in barrier formation by providing an elevated base, nucleus for sedimentation and local sediment supply. Investigation of barriers' subsurface geology provides insight into island formation and evolution. High-resolution shallow seismic data acquired in the island's nearshore zone and interior canals, correlated with existing drillcore data, reveal that Cat Island, MS is situated over an Oxygen Isotope Stage 3 Phase 3 paleochannel located between two topographic high-grounds of the Pleistocene …
Nonattribution Properties Of Jpeg Quantization Tables, Punnya Tuladhar
Nonattribution Properties Of Jpeg Quantization Tables, Punnya Tuladhar
LSU New Orleans Theses and Dissertations
In digital forensics, source camera identification of digital images has drawn attention in recent years. An image does contain information of its camera and/or editing software somewhere in it. But the interest of this research is to find manufacturers (henceforth will be called make and model) of a camera using only the header information, such as quantization table and huffman table, of the JPEG encoding. Having done research on around 110, 000 images, we reached to state that "For all practical purposes, using quantization and huffman tables alone to predict a camera make and model isn't a viable approach". We …
Rethinking Counseling For College: High School Counselors' Perceptions Of Community And Technical Colleges, Desiree Huggins
Rethinking Counseling For College: High School Counselors' Perceptions Of Community And Technical Colleges, Desiree Huggins
LSU New Orleans Theses and Dissertations
While approximately 62% of high school graduates enroll in college, almost half of these students do not return for their second year in school. This demonstratable gap in college interest and reaching actual goals speaks to a need for information on how to facilitate the precollege guidance process to achieve more successful high school graduate and postsecondary institution matches. Much information is available in regard to the college choice process of high school students considering four year colleges and universities; scant information is known about how students discover information about the complete range of postsecondary educational opportunities. In particular, the …
Sensation Seeking And A Real World Stressor: Endocrine And Physiological Effects, Amber Allison
Sensation Seeking And A Real World Stressor: Endocrine And Physiological Effects, Amber Allison
LSU New Orleans Theses and Dissertations
We attempted to identify the psychobiological mechanisms that mediate the process by which the sensation seeking trait culminates in behavior. We used the Sensation Seeking Scales to assess the SS trait in individuals who expressed a desire to skydive. We obtained measures of autonomic (heart rate) and endocrine (salivary cortisol) activity before, during and after skydiving. To distinguish the contribution of novelty, we compared novices (N=29) to experienced jumpers (N=15). All jumpers exhibited HPA-axis activation; novices exhibited a prolonged response and more extreme peak in cortisol compared to experienced jumpers, suggesting that novelty contributes to an intense pattern of stress …
Geology & Geochemistry Of The Kingman Feldspar, Rare Metals And Wagon Bow Pegmatites, Tj Brown
Geology & Geochemistry Of The Kingman Feldspar, Rare Metals And Wagon Bow Pegmatites, Tj Brown
LSU New Orleans Theses and Dissertations
In the Mojave Pegmatite district, located in northwestern AZ, numerous pegmatites intrude syn- to post-collisional Paleoproterozoic granitic rocks. The slightly older Cerbat plutons are associated with the suturing of the Mojave and Yavapai terranes whereas Aquarius granites were emplaced during the Yavapai Orogeny as the sutured terranes docked with North America. A detailed study of 5 pegmatites shows that they are zoned with composite cores and contain REE minerals characteristic of NYF pegmatites. However, they exhibit characteristics atypical for NYF pegmatites including F depletion, white microcline, an absence of columbite and, in the Rare Metals pegmatite, have muscovite and beryl. …
Street Art: Its Display In Public Space And Issues Within A Municipality, Katherine Gunnell
Street Art: Its Display In Public Space And Issues Within A Municipality, Katherine Gunnell
LSU New Orleans Theses and Dissertations
Hip Hop graffiti has been marking our urban landscapes for decades. However street art, a much less researched topic, has claimed notoriety in recent years. Much of the existing research groups hip-hop graffiti, gang graffiti and street art together and calls for a uniform response from communities, city officials and law enforcement. While street artists have made their mark in the urban landscapes of the United States as well as internationally, it is important to define the terms "street art"and "graffiti" and where they deviate from one another in order for cities to begin to address these expressions with any …

A Web Service For Protein Refinement And Refinement Of Membrane Proteins, Kapil Pothakanoori
LSU New Orleans Theses and Dissertations
The structures obtained from homology modeling methods are of intermediate resolution 1-3Ã… from true structure. Energy minimization methods allow us to refine the proteins and obtain native like structures. Previous work shows that some of these methods performed well on soluble proteins. So we extended this work on membrane proteins. Prediction of membrane protein structures is a particularly important, since they are important biological drug targets, and since their number is vanishingly small, as a result of the inherent difficulties in working with these molecules experimentally. Hence there is a pressing need for alternative computational protein structure prediction methods. This …
