Genomic Approaches To Understand Sweetpotato Root Development In Relation To Abiotic Factors, Julio Solis Sarmiento

LSU Doctoral Dissertations

Storage root development is the most important physiological process in sweetpotato. Understanding the underlying genetics is the overall objective of this research. A secondary objective is examining the impact of abiotic stress on gene expression and storage root development. A comprehensive analysis of a high-throughput RNA sequencing data (sweetpotato root, stem, and leaf) and public Expressed Sequences Tags was done to generate a genome-wide transcriptome assembly. About 33 million sequences were assembled into 77,663 unigenes; 52,322 (69.55%) of these unigenes matched to a protein sequence from UniprotKB. Data from de novo root transcriptome enriched the existing sweetpotato gene index by …

Perpetual Requirements Engineering, Manuel Alfonso Peralta

LSU Doctoral Dissertations

This dissertation attempts to make a contribution within the fields of distributed systems, security, and formal verification. We provide a way to formally assess the impact of a given change in three different contexts. We have developed a logic based on Lewis’s Counterfactual Logic. First we show how our approach is applied to a standard sequential programming setting. Then, we show how a modified version of the logic can be used in the context of reactive systems and sensor networks. Last but not least we show how this logic can be used in the context of security systems. Traditionally, change …

How Faith And Leadership Are Connected: A Study Of Catholic Women Administrators In A Southern Public Institution Of Higher Education, Mary Blanchard Wallace

LSU Doctoral Dissertations

Studies concerning spirituality and higher education, particularly for the college student, are beginning to appear in journals, conference papers, and presentations. However, there is little research conducted with professionals in higher education on the construct of spirituality. Spirituality has so many different definitions in the literature, it is difficult to define, and perhaps even more complex to study academically. Using a research-based conceptual model for religious faith, developed within the study of family sciences, this study examines the lived experience of how and why Catholic women administrators connect their faith and leadership in a setting of public institutions of higher …

Predictors Of Resiliency In Women Affected By Hurricane Katrina, Valerie L. Walls

LSU Master's Theses

While the physical devastation of Hurricane Katrina was immediately obvious, the psychological effects of the storm are still being investigated and the positive effects of trauma, although few, have yet to be adequately explored. Although most individuals will experience a trauma during their lifetime, only a small minority experience negative psychological consequences (Breslau, 2002). Resiliency is a quickly developing area in the literature; however, few studies have investigated predictors of resilience and positive outcomes in adults exposed to natural disasters. The purpose of this study was to explore individual factors and predictors of resilience in women exposed to Hurricane Katrina. …

Dynamic Route Choice In Hurricane Evacuation, Meisam Akbarzadeh

LSU Doctoral Dissertations

In this research a framework is developed for modeling route choice in hurricane evacuation. Two behavioral hypotheses are evaluated which together with the route choice model, constitute the contributions of the research. The first hypothesis states that beside congestion, other variables such as familiarity with the route, availability of fuel and shelter, facility class, and length of route have an effect on an evacuees' route choice. The second hypothesis states that as time passes and storm conditions change, the impact each variable has on route choice changes. The logit structure was used for modeling the choice process and stated choice …

Use Of Expanded Shales, Clays And Slates-Light Weight Aggregate For Erosion Control And Grass Establishment On Un-Vegetated Embankments, Murilo De Santana Martins

LSU Master's Theses

High salinity concentrations in soils used to renovation and construct levees adversely affect levee’s performance due to increased susceptibility for erosion problems. Dispersion of the soil particles caused by salts and seal formation affect levee structure stabilization and vegetation establishment is impaired due to lower water infiltration capacity in levees; and high osmotic pressure exerted by salts reducing water availability for seed germination leaving levee surface prone to severe rilling and soil loss from runoff erosion. The objectives of this research were determine if expanded shales, clays, and slates-light weight aggregate (ESCS-LWA) over clay reduces erosion and evaluate how ESCS-LWA …

Coevolutionary Algorithms For The Optimization Of Strategies For Red Teaming Applications, Tirtha Ranjeet

Theses: Doctorates and Masters

Red teaming (RT) is a process that assists an organization in finding vulnerabilities in a system whereby the organization itself takes on the role of an “attacker” to test the system. It is used in various domains including military operations. Traditionally, it is a manual process with some obvious weaknesses: it is expensive, time-consuming, and limited from the perspective of humans “thinking inside the box”. Automated RT is an approach that has the potential to overcome these weaknesses. In this approach both the red team (enemy forces) and blue team (friendly forces) are modelled as intelligent agents in a multi-agent …

Revisiting The Mutual Embeddedness Of Culture And Mental Illness, David Lackland Sam, Virginia Moreira

Online Readings in Psychology and Culture

In this paper, we discuss the intricate relationship between culture and mental illness. Our central position is that there cannot be mental illness without culture. We argue that our limited knowledge to the onset, manifestation, course and outcome of mental illness is due in part to the cross-cultural psychological conceptualization of culture, where culture is seen as an independent variable influencing mental illness, the dependent variable. This is in addition to the limitations of the biomedical model in accounting for the origins of mental illness. Using depression and schizophrenia as examples, we argue for the need to see culture and …

Parent-Teacher Interactions: A Study Of The Dynamics Of Social Influence, Michelle K. Ellis

Theses: Doctorates and Masters

The focus of this study was to explore the nature of parent-teacher interactions and to find evidence of social influence strategies used within their interactions. The literature showed that schools, internationally, nationally, and locally, have implemented parental involvement programs advocated by their respective governments. These programs are designed to encourage parents to interact more with the school and the teachers, forming parent-teacher partnerships to enhance student achievement levels. However, in practice, previous research has also signalled that there are underlying tensions in these parent-teacher partnerships that impact on parent-teacher interactions. This study sought to identify factors that parents and teachers …

The Effectiveness Of Airway Management In The Pre Hospital Treatment Of Traumatic Brain Injury : A Retrospective, Observational Study Of Pre Hospital Treatment Of Traumatic Brain Injury (Tbi) In The Western Australian Ambulance Service, Joseph Cuthbertson

Theses: Doctorates and Masters

There is concern over mortality and the potential for secondary brain injury in the head-injured patient. The use of advanced airway management and rapid sequence intubation in the pre hospital treatment of patients with Traumatic Brain Injury is controversial. Currently in St John Ambulance Service Australia (WA) Inc. three forms of pre hospital treatment are utilized to manage the airway of the adult head-injured patient. If attended by on-road paramedic staff, basic airway management is utilized unless the patient is unconscious and areflexic, in which case advanced airway management utilising endotracheal intubation or laryngeal mask insertion is authorised. In the …

Profiling Instances In Noise Reduction, Sarah Jane Delany, Nicola Segata, Brian Macnamee

Articles

The dependency on the quality of the training data has led to significant work in noise reduction for instance-based learning algorithms. This paper presents an empirical evaluation of current noise reduction techniques, not just from the perspective of their comparative performance, but from the perspective of investigating the types of instances that they focus on for re- moval. A novel instance profiling technique known as RDCL profiling allows the structure of a training set to be analysed at the instance level cate- gorising each instance based on modelling their local competence properties. This profiling approach o↵ers the opportunity of investigating …

Can Professional Development Improve Teachers’ Perceptions About Inclusive Teaching In An Inner City School, Solomon Homidas

Abraham S. Fischler College of Education ETD Archive

This applied dissertation examined the question of whether professional development can improve teachers’ perceptions of inclusive teaching in an inner city school. The study drew upon survey methods to collect measurements of teachers' perceptions about inclusive teaching before and after professional development sessions. The hypothesis was that exposure to professional development would give teachers an improved impression of inclusive teaching, which in turn could make them more committed to the inclusive teaching paradigm. If the hypothesis was correct, the study would show that professional development should be considered an important component of developing teachers who work in inclusive settings, especially …

Critical Resiliency: A Case Study Of Latino Students’ Experiences In Advanced-Level High School Courses, Eric J. Chagala

Abraham S. Fischler College of Education ETD Archive

The achievement gap has been at the center of much educational discourse for the past 20 years, and it has become even more prevalent since the introduction of the No Child Left Behind Act in 2001. References in the literature regarding the achievement gap often center on raising ethnic minority and low-socioeconomic students to the same average academic performance as White, middle-class students (Gandara, 2005). This case study went beyond that and examined the achievement gap in terms of the experiences of 1stgeneration, college-bound, and low-income Latino students in advanced-level high school courses, such as advanced placement (AP) and international …
