In short order both ice hockey and basketball evolved from amateur, recreational activities to professional sport and entertainment businesses. This study analyzes, contextualizes, and discusses the layout of the urban multipurpose facilities that emerged to house both professional hockey and professional basketball, with particular attention paid to the facilities of the National Hockey League and National Basketball Association. The study uses the lens of modernization and the ideal-type heuristic device to extend Bale’s and Seifried’s facility evolution models. In addition to providing …

The Rise And Fall Of Focused Deterrence Initiatives, Chandra Lynore Joseph

LSU Doctoral Dissertations

Following the national uptick of violence across the country, societal angst has once again begun to surface. Those in positions of authority began to look to the criminal justice system for ways to address this cyclical issue. Traditionally, applying law enforcement crackdowns and increased penalties and sanctions to the offenders were the main topics of discussion. However, over the last two decades, problem-oriented policing has begun to emerge. Problem-oriented policing works to identify why things are going wrong and to frame responses using a wide variety of often untraditional approaches (Goldstein 1979). One of the problem-oriented frameworks known as the …

Metamorphosis, Claire M. Kane

LSU Master's Theses

“Metamorphosis” is a product of the symbiotic relationship between my paintings and written narrative and consists of large-scale paintings and written components informed by my research of children’s art, outsider art, Louisiana’s landscapes, performance, artists of influence, mythology, and spiritual texts. The paintings are informed by my own sensory experiences of local landscapes. I utilize these immersions in nature and subsequent studies to create a mode of communication for my narrative to unfold on the canvas. The exhibition consists of seven large scale mixed media paintings and one smaller study mounted on the walls of the gallery space.

Developing Management Strategies For Taproot Decline, Xylaria Sp., In Soybean, Myra Purvis

LSU Master's Theses

Soybean (Glycine max) is one of the most important oilseed crops in the world. Taproot decline is a recently discovered disease caused by Xylaria sp., a novel species located within the Xylaria arbuscula aggregate. Foliar symptoms include interveinal chlorosis and necrosis, and upon further investigation, there are often dead plants adjacent within the row. Many other soybean diseases have similar foliar symptoms; therefore, more examination is usually required for proper identification. Soybean debris from previous years is suspected to be the primary source of inoculum. Plants may be infected at any point during the growing season, often …

Influence Of P Fertility On Sweetpotato Rooting During Containerized Transplant Production, Lee T. Rouse

LSU Master's Theses

A market for edible landscape transplants continues to increase for vegetable production in the home landscape. A method for extending the salability of sweetpotato transplants in retail outlets is needed because containerized transplants can develop spiraling roots and deformed storage roots. Implementing traditional techniques to ameliorate container-bound roots before planting in the landscape is not advisable. Altering P fertility is a non-chemical and non-mechanical method for slowing sweetpotato rooting. Therefore, sweetpotato cuttings were planted in 100% sand-filled containers and fertilized at 0, 5, 10, 15, 20, and 31 mg L^-1 using a modified Hoagland solution over a 6-week period. …

Development Of Biological Tools To Promote Rice Health And Growth, Ateet Maharjan

LSU Master's Theses

Sheath blight (ShB - caused by Rhizoctonia solani) and bacterial panicle blight (BPB - caused by Burkholderia glumae) are economically important rice diseases in Louisiana and other rice-growing regions. Fungicides and oxolinic acid are used to manage ShB and BPB, respectively, but these chemical methods are not sustainable economically and ecologically. Besides diseases, plant utilizable nitrogen (N) in the soil is inadequate for optimum crop yield, leading to the use of inorganic fertilizers and making agriculture less sustainable. To develop alternative biological control methods for protecting rice plants from diseases, rice-associated bacteria were screened based on their antagonistic …

Effects Of Silicon And Beneficial Bacteria On Sheath Blight Of Rice And The Microbial Community Of Rice Rhizosphere, Jhonson Leonard

LSU Master's Theses

Sheath blight (ShB), caused by Rhizoctonia solani Kühn, is an economically important soil-borne disease of rice (Oryza sativa) that can cause up to 50 % yield losses. Application of fungicides is the most effective and commonly used method for managing sheath blight. However, the pathogen can develop new resistant strains upon continuous exposure to a fungicide. Moreover, the use of inorganic fungicides is not eco-friendly. The utilization biological control agents (BCAs) can be a more sustainable and safe means of managing ShB. To develop alternate strategies for ShB management, I am exploring the effect of the silicon (Si) …

High Performance Fuzz Testing Of Memory Forensics Frameworks, Arian Dokht Shahmirza

LSU Master's Theses

The analysis of the volatile memory (RAM) of a computer system, known as memory forensics, is a critical component of modern digital forensics investigations. Since the evidence provided by memory forensics is vital, it is necessary for there to be automated solutions that implement the analysis. Volatility is the most widely used memory forensics framework and also contains the most functionality of all tools publicly available. Volatility, as well as all other memory forensics frameworks, are extremely complex software systems as they must parse a substantial number of in-memory data structures and their associated values. Given the reliance on memory …

Faculty Publications

© 2019 Wiley Periodicals, Inc. Herein, we present a facile and comprehensive synthetic methodology for the preparation of polyester-polyamidoamine (PAMAM) (i.e., polyester: polylactide [PLA] (hydrophobic) and polyamidoamine, PAMAM [hydrophilic]) polymers. A library of PLA-PAMAM linear dendritic block copolymers (LDBCs) in which both l and d, l polylactide were employed in mass ratios of 30:70, 50:50, 70:30, and 90:10 (PLA:PAMAM) were synthesized and analyzed. When placed in aqueous media, the immiscibility of the hydrophilic and hydrophobic segments leads to nanophase-segregation exhibited as the formation of aggregates (e.g., vesicles, worms, and/or micelles). By employing both stereochemical configurations of PLA, the differentiation in …

Characterizing Diameter Distributions For Uneven-Aged Pine-Oak Mixed Forests In The Qinling Mountains Of China, Shuaichao Sun, Quang V. Cao, Tianjian Cao

Faculty Publications

Pine-oak mixed forests in the Qinling Mountains are an essential part of the ecosystem in Northwestern China. Diameter distribution models for four species groups of pine-oak mixed forests were developed using the Weibull function. Both moment and hybrid estimation approaches were used to predict theWeibull parameters. For each approach, three fitting methods (maximum likelihood estimator regression (MLER), cumulative distribution function regression (CDFR) and modified CDFR) were employed to obtain estimates for coefficients of regression equations to predict Weibull parameters. Overall results indicated that the Moment Estimation approach was better than the Hybrid approach, and that the CDFR method was superior …

The Impact Of Formal Panhellenic Recruitment On The Development Of Efficacy For Sorority Women, Amanda Jill Horvat

LSU Doctoral Dissertations

Little to no research has been conducted to assess the impact of formal sorority recruitment processes on efficacy levels of sorority women. While numerous studies have been conducted concerning the development of individual women and skills gathered throughout their collegiate experience, there has been limited research on how participation in sorority recruitment may impact psychological and physiological states, and increase or decrease self and collective efficacy.

If the original intent of sororities was to provide friendship, support, and encouragement, are current formal recruitment methods, supported by the National Panhellenic Conference, meeting that goal? Addressing this question requires an in-depth understanding …

The Religion Of Policing: Race, Riots, And The Killing Of Alton Sterling, Landon Jay Douglas

LSU Doctoral Dissertations

Deadly force encounters with black people and law enforcement officials are far too numerous and encounters that result in the death of civilians do not always result in disciplinary actions against officers, many of whom are white. The high-profile killings of black people in America require an in-depth analysis of race, policing, and the origins of tactics used by law enforcement against black people, which is not merely data-driven, but also theory driven. In trying to understand the disparate treatment experienced by black people at the hands of law enforcement officials, and the extent to which many Americans, mostly white …

Large-Scale Data Analysis And Deep Learning Using Distributed Cyberinfrastructures And High Performance Computing, Richard Dodge Platania

LSU Doctoral Dissertations

Data in many research fields continues to grow in both size and complexity. For instance, recent technological advances have caused an increased throughput in data in various biological-related endeavors, such as DNA sequencing, molecular simulations, and medical imaging. In addition, the variance in the types of data (textual, signal, image, etc.) adds an additional complexity in analyzing the data. As such, there is a need for uniquely developed applications that cater towards the type of data. Several considerations must be made when attempting to create a tool for a particular dataset. First, we must consider the type of algorithm required …

Can Cooler Heads Prevail? New Media Technology And Affective Polarization, Brian Kendall Watson

LSU Doctoral Dissertations

Are new media technologies stirring up negative partisan feelings in the American public? Can researchers find ways of using new media tools to reduce affective polarization? Relying on a series of experiments featuring online newsfeeds and social media discussions, this dissertation seeks to answer these questions by testing the influence of partisan news and political discussions in realistic Internet environments. Two custom news “portals” (2016, 2018) expose participants to actual partisan news content. Two Facebook discussion experiments (2017, 2019) randomly assign participants to start real political discussions on their personal social media accounts, using discussion-initiation strategies designed to reduce partisan …

The Religious Impact: Understanding The Influence Of Religiosity On Attitudes Toward Policy Issues, Angela Farizo Mccarthy

LSU Doctoral Dissertations

The purpose of this dissertation is to shed light on the influence of religion on Americans’ attitudes toward policy concerns. How do denominational affiliation, religious participation, and religious beliefs influence one’s views on social and/or economic policies? I consider the impact of religious belonging, religious behaving, and religious believing—also known as the “3B’s” – on public opinion toward contemporary issues in the United States. In this comprehensive analysis, I discover the importance of including the religious dimensions in models of public policy attitudes. The first part of this project is to outline the current state of the literature and present …

Beyond An Accommodation: A Mixed Methods Study Of Diversity Engagement In Academic Curriculum, Micah Jaryl Glenn

LSU Doctoral Dissertations

Currently, 45% of all college students are classified as racial/ethnic minorities, while 56% of college students are female (NCES, 2018a). By 2030, nearly half of the estimated United States population will be composed of racial/ethnic minorities (Cortes, 1991). With this exponential growth of minorities attending institutions of higher education, there is the assumption that students have begun to engage in and promote diversity and inclusion. However, in 2008, Boysen and Vogel (2009) found that 40% of teachers and 50% of students encountered implicit or explicit bias while in college. In 2017, within four months, over 330 reported biased incidents occurred …

"If They Don't Tell You, The Hair Will": Hair Narrative In Contemporary Women's Writing, Darina Pugacheva

LSU Doctoral Dissertations

The history of colonial and racial oppression made hair stories and testimonials fundamental to understanding hair as a unifying element particular for women of African descent in the post-slavery era. Seen as such, their hair narrations provide the first-person perspective of their life experiences while at the same time inviting a critical investigation of colonial and racial oppression. Contemporary women writers develop these types of narrations into a special language of hair that helps them tell a story that is not apparent or straightforward. This literary device that uses hair to uncover deeper social and political issues is bound up …

Chronic Nucleoside Reverse Transcriptase Inhibitors Disrupt Mitochondrial Homeostasis And Promote Premature Endothelial Senescence, Yi-Fan Chen

LSU Doctoral Dissertations

Combination antiretroviral therapy (cART) has been hugely successful in reducing the mortality associated with human immunodeficiency virus (HIV) infection, resulting in a growing population of people living with HIV (PLWH). Since PLWH now have a longer life expectancy, chronic comorbidities have become the focus of the clinical management of HIV. For example, cardiovascular complications are now one of the most prevalent causes of death in PLWH. Nucleoside reverse transcriptase inhibitors (NRTIs) are the backbone of cART, and two NRTIs are typically used in combination with one drug from another drug class, such as a non-NRTI, a protease inhibitor or an …

Divergent Transcriptional Regulation Of Suppressors Of Cytokine Signaling Genes In Adipocytes, Paula Mota De Sa

LSU Doctoral Dissertations

The Janus Kinase - Signal Transducer and Activator of Transcription (JAK-STAT) signaling pathway transduces several signals crucial for development and homeostasis. Suppressors of cytokine signaling (SOCS) proteins control JAK-STAT signaling via a negative feedback loop. The transcription factor STAT5 is known to play a significant role in fat cell development and function, and several studies suggest that acetylation may affect STAT5 transcriptional activity. To test this hypothesis, we treated 3T3-L1 adipocytes with growth hormone (GH) to activate STAT5 in the presence or absence of histone deacetylase (HDAC) inhibitors. STAT5 acetylation levels were low in adipocytes and mostly unchanged by the …

Neutron production in giga electron volt-scale neutrino interactions is a poorly studied process. We have measured the neutron multiplicities in atmospheric neutrino interactions in the Sudbury Neutrino Observatory experiment and compared them to the prediction of a Monte Carlo simulation using genie and a minimally modified version of geant4. We analyzed 837 days of exposure corresponding to Phase I, using pure heavy water, and Phase II, using a mixture of Cl in heavy water. Neutrons produced in atmospheric neutrino interactions were identified with an efficiency of 15.3% and 44.3%, for Phases I and II respectively. The neutron production is measured …

Field Performance And Cost Effectiveness Of Crack Sealing In Flexible And Composite Pavements, Momen Ragab Mousa

LSU Doctoral Dissertations

Surface cracking is one of the major surface distresses in asphalt concrete (AC) pavement, allowing water infiltration through the cracks, causing stripping in asphalt pavement layers, and weakening and deteriorating the base and/or subgrade. Its treatment, therefore, is one of the major activities in pavement preservation for many state DOTs. Among the various treatment methods currently available to preserve AC pavement with existing surface cracking are various forms of crack sealing. Crack sealing is not a common practice to Louisiana highways since the benefit of such treatment appears to be affected by the elevation of the ground water table. Studies …
