A Comparison Between Functional And Traditional Interface Displays In Support Of Console Operator Performance And Workload, Sophie Lynn Schwartz

LSU Master's Theses

In the petrochemical industry, schematic interfaces have been traditionally used as the main interface for console operators to monitor activities. There is limited research in this industry investigating alternative interface types to better support console operator’s decisions during alarm management. Furthermore, even less of that research includes eye-tracking as a measure for console operator situation awareness (SA). This research aimed to investigate an alternative interface, called a functional interface, in its level of support of console operator situation awareness, accuracy, subjective workload, and average response time. Additionally, eye-tracking was incorporated to explore its value as measure for situation awareness on …

Initial Development And Validation Of The Student Wellbeing Teacher-Report Scales, Anthony Joseph Roberson

LSU Master's Theses

Given that youth mental health is associated with their success in school and in life more broadly, it is important that school-based psychological service providers embrace best-practice prevention and intervention strategies that target mental health when working with student populations. One line of study in this area has begun exploring the incorporation of a dual-factor model of mental health within universal screening systems in schools. The dual-factor model is differentiated from the traditional unidimensional mental health model, which focuses on the presence or absence of psychopathology, by conceptualizing mental health alternatively as consisting of both psychopathology and wellbeing dimensions. The …

Option Volatility & Arbitrage Opportunities, Mikael Boffetti

LSU Master's Theses

This paper develops several methods to estimate a future volatility of a stock in order to correctly price corresponding stock options. The pricing model known as Black-Scholes-Merton is presented with a constant volatility parameter and compares it to stochastic volatility models. It mathematically describes the probability distribution of the underlying stock price changes implied by the models and the consequences. Arbitrage opportunities between stock options of various maturities or strike prices are explained from the volatility smile and volatility term structure.

Driver Engagement In Secondary Tasks: Behavioral Analysis And Crash Risk Assessment, Mengqiu Ye

LSU Master's Theses

Distracted driving has long been acknowledged as one of the leading causes of death or injury in roadway crashes. The focus of past research has been mainly on the change in driving performance due to distracted driving. However, only a few studies attempted to predict the type of distraction based on driving performance measures. In addition, past studies have proven that driving performance is influenced by the drivers’ socioeconomic characteristics, while not many studies have attempted to quantify that influence. In essence, this study utilizes the rich SHRP 2 Naturalistic Driving Study (NDS) database to (a) develop a model for …

An Examination Of Autism Symptomatology In Young Children With Family History Of Autism Spectrum Disorder, Jasper Abarte Estabillo

LSU Master's Theses

Multiple genetic and environmental factors have roles in the etiology of autism spectrum disorder (ASD). Thus, researchers have become increasingly interested in studying family members of individuals with ASD in order to examine possible risk factors and to identify early markers of the disorder. While family history of ASD may put an individual at risk for developing autism, there is limited research examining how the degree of relationship to the affected individual may be related to an individual’s presenting ASD symptomatology. Because closer familial relationships (i.e., first-degree relatives) have more shared genetic material and tend to have increased common environment …

Everglades Mangrove Forest Response To Large-Scale Disturbance: Long-Term Assessment Of Structural And Functional Properties, Tess Marie Danielson

LSU Master's Theses

The impact (i.e., defoliation and mortality) associated with large-scale natural disturbance events is capable of significantly altering ecosystem structure (e.g., biomass) and function (e.g., productivity) in mangrove wetlands. These pulsing events provide an opportunity to assess ecosystem resilience (i.e., recovery to pre-disturbance conditions) by evaluating the immediate and long-term ecosystem response trajectory (i.e., disturbance magnitude, recovery time). I hypothesized that 1) there are specific properties of disturbance that can be characterized and fit to a general forest disturbance model, and that 2) a mangrove forest recovery trajectory (i.e. recovery duration and rate) is dependent on the disturbance magnitude and initial …

Reentering Survivors: Invisible At The Intersection Of The Criminal Legal System And The Domestic Violence Movement, Courtney Cross

Scholarly Works

Like all returning citizens, women coming home after incarceration face significant challenges to successful reentry. In addition to the collateral consequences of their criminal convictions, reentering women also encounter uniquely gendered obstacles. This Article explores one such obstacle: the relationship between women's reentry and domestic violence. Women on probation or parole who are also experiencing domestic violence too often fall into a blind spot in which the structure of community supervision pressures them to remain in unsafe homes and also punishes them when the abuse they endure interferes with their ability to comply with the conditions of their release. Because …

Constructing The Search Template: Episodic And Semantic Influences On Categorical Template Formation, Juan D. Guevara Pinto

LSU Master's Theses

Search efficiency is usually improved by presenting observers with highly detailed target cues (e.g., pictures). However, in the absence of accurate target cues, observers must rely only on categorical information to find targets. Models of visual search suggest that guidance in a categorical search results from matching categorically-diagnostic target features in the search display to a top-down attentional set (i.e., the search template), but the mechanisms by which such attentional set is constructed have not been specified. The present investigation examined the influences of both semantic and episodic memory on search template formation. More precisely, the present study tested whether …

Expandable Proppants For Hydraulic Fracturing, Livio Yang Santos

LSU Master's Theses

Hydraulic fracturing is recognized as the primary technique to achieve economic oil and gas production from low permeability reservoirs like shale and tight-sand formations. One of the main challenges facing the oil and gas industry is maintaining the proppant functionality in the subsurface where replacement of proppant is only possible by expensive refracturing operations. Proppant crushing and proppant embedment have posed challenges for sustainable production from stimulated wells especially in soft and deep formations like Haynesville Shales. Experimental measurements show the strong impact of proppant stress and proppant embedment on reducing fracture conductivity. In this work, we introduce a new …

Enhancing Program Soft Error Resilience Through Algorithmic Approaches, Sui Chen

LSU Master's Theses

The rising count and shrinking feature size of transistors within modern computers is making them increasingly vulnerable to various types of soft faults. This problem is especially acute in high-performance computing (HPC) systems used for scientific computing, because these systems include many thousands of compute cores and nodes, all of which may be utilized in a single large-scale run. The increasing vulnerability of HPC applications to errors induced by soft faults is motivating extensive work on techniques to make these applications more resilient to such faults, ranging from generic techniques such as replication or checkpoint/restart to algorithm-specific error detection and …

The Attentional Mechanisms Of Active Forgetting, Laura Lee Heisick

LSU Master's Theses

Recent work has shown that intentional forgetting of distracting, erroneous, or irrelevant information aids memory, and relies on active, effortful processes. Two experiments investigated the underlying attentional mechanisms that are active during directed forgetting (DF). Across both experiments, participants completed a modified item-method DF task, in which they received memory instructions to remember or forget individual images for a subsequent memory test. Participants studied items associated with remember or forget instructions before they were shown a subliminal presentation of target items. Finally, participants responded to probes by identifying briefly shown letters to assess how attention and item identity information are …

What’S Art Got To Do With It?: A Rebellious Lawyer Mindset In Transactional Practice, Patience A. Crowder

Scholarly Works

The geography and demographics of poverty have changed significantly over the last 20 years to trigger a national conversation about race and class and inequality. This conversation compels the need to examine anew the pervasiveness of race and class discrimination- in both traditionally obvious and nonobvious settings. Calling on rebellious lawyering principles, this Article recognizes that the comprehensive examination of questions of inequality requires the consideration and exploration of remedies that extend beyond the realm of litigation to contemplate transactional advocacy in the public interest-and presents a rebellious lawyer mindset in transactional practice.

Applying Deep Learning Techniques To The Analysis Of Android Apks, Robin Andrew Nix

LSU Master's Theses

Malware targeting mobile devices is a pervasive problem in modern life and as such tools to detect and classify malware are of great value. This paper seeks to demonstrate the effectiveness of Deep Learning Techniques, specifically Convolutional Neural Networks, in detecting and classifying malware targeting the Android operating system. Unlike many current detection techniques, which require the use of relatively rigid features to aid in detection, deep neural networks are capable of automatically learning flexible features which may be more resilient to obfuscation. We present a parsing for extracting sequences of API calls which can be used to describe a …

“What Credit Is That To You?” The Social Context Of Moneylending In Medieval England A Comparative Study 1340-1509, Elizabeth Ann Green

LSU Master's Theses

This study makes use of the manorial court rolls of Dyffryn Clwyd, a cantref in Northern Wales, and the certificates of debt from London to examine the lives of two medieval usurers, Ieuan Kery and Sir William Capell, between the years 1340 to 1352 , and 1478 to 1509 . By examining the life of these two individuals who both operated one of the rarest, most socially complex occupations of his place and time, this study begins to expose the ways in which usury helped to shape the fabric of late Medieval culture in the British Isles. The singular focus …

Madagascar’S Mangroves: Quantifying Nation-Wide And Ecosystem Specific Dynamics, And Detailed Contemporary Mapping Of Distinct Ecosystems, Trevor G. Jones, Leah Glass, Samir Gandhi, Lalao Ravaoarinorotsihoarana, Aude Carro, Lisa Benson, Harifidy Rakoto Ratsimba, Chandra Giri, Dannick Randriamanatena, Garth Cripps

Environmental Science and Management Faculty Publications and Presentations

Mangrove ecosystems help mitigate climate change, are highly biodiverse, and provide critical goods and services to coastal communities. Despite their importance, anthropogenic activities are rapidly degrading and deforesting mangroves world-wide. Madagascar contains 2% of the world’s mangroves, many of which have undergone or are starting to exhibit signs of widespread degradation and deforestation. Remotely sensed data can be used to quantify mangrove loss and characterize remaining distributions, providing detailed, accurate, timely and updateable information. We use USGS maps produced from Landsat data to calculate nation-wide dynamics for Madagascar’s mangroves from 1990 to 2010, and examine change more closely by partitioning …

Climate And Bark Beetle Effects On Forest Productivity — Linking Dendroecology With Forest Landscape Modeling, Alec M. Kretchun, E. Louise Loudermilk, Robert M. Scheller, Matthew Hurteau, Soumaya Belmecher

Environmental Science and Management Faculty Publications and Presentations

In forested systems throughout the world, climate influences tree growth and aboveground net primary productivity (ANPP). The effects of extreme climate events (i.e., drought) on ANPP can be compounded by biotic factors (e.g., insect outbreaks). Understanding the contribution of each of these influences on growth requires information at multiple spatial scales and is essential for understanding regional forest response to changing climate. The mixed conifer forests of the Lake Tahoe Basin, California and Nevada, provide an opportunity to analyze biotic and abiotic influences on ANPP. Our objective was to evaluate the influence of moisture stress (climatic water deficit, CWD) and …

Working Memory And Interference Control In Children With Specific Language Impairment, Klara Marton, Naomi Eichorn, Luca Campanelli, Lilla Zakarias

Publications and Research

Language and communication disorders are often associated with deficits in working memory (WM) and interference control. WM studies involving children with specific language impairment (SLI) have traditionally been framed using either resource theories or decay accounts, particularly Baddeley's model. Although significant interference problems in children with SLI are apparent in error analysis data from WM and language tasks, interference theories and paradigms have not been widely used in the SLI literature. A primary goal of the present paper is to provide an overview of interference deficits in children with SLI. Review of the extant literature on interference control shows deficits …

Collective Intervention: An Analysis Of The Political Issues Regarding Secession, Self-Determination, And Sovereignty In The Republic Of Kosovo, Benjamin Werthan

University Honors Theses

In 2008, the Republic of Kosovo, after years of war and internal conflicts between the ethnic Albanians and Serbians who lived in the territory, finally received status as an independent state. The process was long and even after declaring independence the Republic still had to fight for such recognition. This thesis explores that process, starting with the years prior to the Yugoslav Wars, through the Republic of Kosovo’s Declaration of Independence and the subsequent International Court of Justice advisory opinion. The purpose of this thesis is to explore the concepts of self-determination and state sovereignty with regard to the actions …

Who Matters?: Effective Classroom Management Strategies For Multicultural Elementary Education, Erica Bailey-Ramos

University Honors Theses

Current classroom management procedures, which are dominated by white affluent culture, are not conducive to effectively teaching the increasingly growing diverse school population. Differing backgrounds in a classroom are often viewed as deficits that teachers need to correct instead of individual strengths that add to the classroom knowledge. Currently, the public education system is making students conform to the school culture, instead of the school changing to reflect the community. Multicultural education is for all students, preparing them for the real world by teaching tolerance, acceptance, and learning through multiple perspectives. Current research agrees that a shift in management techniques …

The collection of poems explores personal, domestic spaces and the ways in which external forces are exerted upon them.

Preventing Campus Sexual Assault: Evaluating Studies Of Male Offender Prevention Programs And Determining Best Practices, Cam Tu Tran

University Honors Theses

Campus sexual assault is becoming a highly publicized issue, with the U.S. White House recently releasing a report urging universities to improve prevention efforts through systematic evaluations, policies, reporting procedures, and victim support (U.S. White House Task Force, 2014). Although these recent headlines have focused attention on universities’ responses to sexual assault, research in prevention program effectiveness has been conducted in university settings for over 30 years. This thesis focuses on past research in primary prevention in facilitated educational trainings for college men. This thesis reviews studies on interventions implemented on college campuses by exploring the most effective practices, and …

Mills And Veblen: An Institutional Analysis, Matthew Klosterman

University Honors Theses

This inquiry considers and also seeks to establish theoretical relationships between the thinking and contributions of Thorstein Veblen and C. Wright Mills. Selected writings of Veblen have not only formed new approaches to the discipline of Economics, but also influenced prominent scholars, like Mills. In his contributions, Veblen employs various approaches to social science analysis, such as use of dichotomy (Veblenian Dichotomy), subreption, and cumulative causation in his efforts to describe social change within an evolutionary-institutionalist framework. While not being explicit, some contributions of Mills utilize similar approaches advanced earlier by Veblen. In summary, Mills’ contributions to sociology appear to …

Queering Sugar: Kara Walker’S Sugar Sphinx And The Intractability Of Black Female Sexuality, Amber Jamilla Musser

Publications and Research

This essay analyzes the controversy surrounding artist Kara Walker’s 2014 installation, A Subtlety, or the Marvelous Sugar Baby, to unpack the pleasures and dangers that subtend discussions of black female sexuality. What Walker announced as a tribute to the labor of brown and black bodies produced myriad conversations about pleasure, danger, and black female sexuality. Most art critics argued that the piece reclaimed black female agency; many visitors criticized the work (and the public response to it) as disrespectful and problematic. In the essay, I argue that both of these responses highlight the difficulty of talking about black female …

Color Associations As Advertising Strategies: An Analysis Of Consumer Attitudes Toward The Healthfulness Of Energy Bar Packaging, Rachel Lotz

University Honors Theses

Color plays a strong role in shaping consumers’ attitude toward brands, expectations, and likeability in the field of advertising. Associations with colors are formed within consumers’ culture and are often universal in meaning. Through three studies, the role of color in relationship to perceived healthfulness on energy bar packaging is observed. The results show a strong correlation between a particular color associated with healthfulness due to preconceived color associations often highlighted in advertising strategies. However the results raised unexpected, yet insightful correlations with other colors, which participants identified as healthy. When participants were asked to pick the energy bar that …

What Do Physicians Know About Global Plans To Stop Tuberculosis? Interviews From Five Countries, Hannah Johnson

University Honors Theses

Tuberculosis ranks alongside HIV as the leading cause of death worldwide. This fact is complicated by drug-resistant versions of tuberculosis. Furthermore, the limited availability and high cost of stronger antibiotics creates a barrier to treating drug-resistant tuberculosis. In 2000, the United Nations organized to fight tuberculosis via Millennium Development Goal six and the Global Plan to Stop Tuberculosis. In an effort to understand limitations on the effectiveness of global programs, this research addresses the following question: What do physicians know about global programs for TB? Mixed methods, involving both quantitative and qualitative data, were used to obtain the results of …

The United States’ Criminal Justice System Divided* : …On The Connection Between The Exclusionary Rule And Preserving Civil Liberties, Alexandre Pomar

University Honors Theses

The injustice by professionals within the criminal justice system gives rise to societal opinion that purports that these respective agencies lack a clear perception of their professional conduct. This invidious neglect toward societal opinion preempts the divide among law enforcement agencies--most specifically--and the United States population. The impaired perception on professional conduct the criminal justice professionals suffer from nationwide owes itself to the misuse of authority and a subsequent lack of accountability for improper actions. Over time, the dissolving of one’s civil liberties has perpetuated in accord to the deference awarded to law enforcement agencies and the courts that allow …

Lobbying The European Parliament: Identifying Changing Trends Post-Treaty Of Lisbon, Jason Means

University Honors Theses

This study evaluates the assumption that lobbying at the EP level steadily increased after the Treaty of Lisbon, and also the expectation that there would be no variation in lobbying activity (measured by types of lobbyists) during this period. Research was conducted through the utilization of data from the European Transparency Register as scraped by Friedrich Lindenberg between 2012 and 2014. After categorizing more than 16,000 entries it was determined that the amount of lobbyists targeting the EU has steadily increased, and the primary lobbying group between the researched period was Business--though, there was a significant amount of variation between …

The European Coal And Steel Community: The Path Towards European Integration, Nicholas Hudson

University Honors Theses

This inquiry seeks to establish the importance of the European Coal and Steel Community (ECSC) and its key role as the foundation for deeper European integration projects, which ultimately have manifested in the European Union seen today. By the end of the Second World War, the European continent was left in ruins, with nations desperately seeking to rebuild their economies and infrastructures, while also attempting to create a stability that would bring lasting peace to a region historically torn apart by war. European leaders, including the French diplomat Jean Monnet, were faced with the challenge of increasing output and employment …

Oregon Youth Peer Courts: Grand Jury Style, Sierra Udland

University Honors Theses

Youth Courts are diversionary programs for first time misdemeanors committed by youth. The court is made up of the youth's peers who interact with the defendant and ultimately impose a sentence. In this study two Oregon Youth Courts are examined to discover if the program goals of restorative justice are present. The courts utilize a specific style of peer jury model, called the "Grand Jury style" because the jurors ask the questions and decide the case. Eight cases are observed with a subset of jurors surveyed about sentencing decisions. Restorative justice principles are found through both modes of data collection. …
