Economically Benevolent Dictators: Lessons For Developing Democracies, Ronald J. Gilson, Curtis J. Milhaupt

Faculty Scholarship

The post-war experience of developing countries leads to two depressing conclusions: only a small number of countries have successfully developed; and development theory has not produced development. In this article we examine one critical fact that might provide insights into the development conundrum: Some autocratic regimes have fundamentally transformed their economies, despite serious deficiencies along a range of other dimensions. Our aim is to understand how growth came about in these regimes, and whether emerging democracies might learn something important from these experiences.

Our thesis is that in these economically successful countries, the authoritarian regime managed a critical juncture in …

Profiling And Consent: Stops, Searches And Seizures After Soto, Jeffrey Fagan, Amanda Geller

Faculty Scholarship

Following Soto v State (1999), New Jersey was among the first states to enter into a comprehensive Consent Decree with the U.S. Department of Justice to end racially selective enforcement on the state’s highways. The Consent Decree led to extensive reforms in the training and supervision of state police troopers, and the design of information technology to monitor the activities of the State Police. Compliance was assessed in part on the State’s progress toward the elimination of racial disparities in the patterns of highway stops and searches. We assess compliance by analyzing data on 257,000 vehicle stops on the New …

Philosophical Legal Ethics: Ethics, Morals, And Jurisprudence, Alice Woolley, W. Bradley Wendel, William H. Simon, Stephen Pepper, Daniel Markovitz, Katherine R. Kruse, Tim Dare

Faculty Scholarship

The authors and moderator David Luban participated in a plenary session of the International Legal Ethics Conference IV, held at Stanford. Each author answered and discussed questions arising from short papers they had written about the principal concern of legal ethics was the morality of lawyers, the morality of clients, or the morality of laws?

Those papers, which are to be published in Legal Ethics, are compiled here, along with the question and background information with which the panelists were provided.

Meditaciones Postmodernas Sobre El Castigo: Acerca De Los Límites De La Razón Y De Las Virtudes De La Aleatoriedad (Una Polémica Y Un Manifiesto Para El Siglo Xxi), Bernard E. Harcourt

Faculty Scholarship

In Spanish
Durante la Modernidad, el discurso sobre la pena ha girado circularmente en torno a tres grupos de interrogantes. El primero, surgido de la propia Ilustración, preguntaba: ¿En qué basa el soberano su derecho de penar? Nietzsche con mayor determinación, pero también otros, argumentaron que la propia pregunta implicaba ya su respuesta. Con el nacimiento de las ciencias sociales, este escepticismo hizo surgir un segundo conjunto de interrogantes: ¿Cuál es, entonces, la verdadera función de la pena? ¿Qué es lo que hacemos cuando penamos? Una serie de críticas ulteriores – de metanarrativas, funcionalistas o de objetividad científica – debilitaron …

Neighborhood Factors Relevant For Walking In Older, Urban, African American Adults, N. A. Gallagher, Kimberlee A. Gretebeck, Jennifer C. Robinson, Elisa R. Torres, Susan L. Murphy, Kristy K. Martyn

College of Nursing Faculty Research and Publications

Focus-group and photo-voice methodology were used to identify the salient factors of the neighborhood environment that encourage or discourage walking in older, urban African Americans. Twenty-one male (n = 2) and female (n = 19) African Americans age 60 years and older (M = 70 ± 8.7, range = 61–85) were recruited from a large urban senior center. Photographs taken by the participants were used to facilitate focus-group discussions. The most salient factors that emerged included the presence of other people, neighborhood surroundings, and safety from crime, followed by sidewalk and traffic conditions, animals, public walking tracks …

The Pacto De Sangre In The Late Nineteenth-Century Nationalist Emplotment Of Philippine History, Filomeno V. Aguilar Jr

History Department Faculty Publications

The Pacto de Sangre (Blood Compact), despite its crucial significance in Filipino conceptions of history, is seldom interrogated in Philippine historiography. The event that happened in Bohol in 1565, involving Sikatuna and Legazpi, was narrativized in the late nineteenth century and became integral to the nationalist emplotment of the past. However, the two principal narrative strands of Marcelo del Pilar and Andres Bonifacio differed owing to divergent political projects. This article revisits the making of a founding myth of Filipino nationhood in light of scholarship on ancient blood oaths and the historical account of the encounter of Sikatuna and Legazpi.

Why The Supreme Court Cares About Elites, Not The American People, Lawrence Baum, Neal Devins

Faculty Publications

Supreme Court Justices care more about the views of academics, journalists, and other elites than they do about public opinion. This is true of nearly all Justices and is especially true of swing Justices, who often cast the critical votes in the Court’s most visible decisions. In this Article, we will explain why we think this is so and, in so doing, challenge both the dominant political science models of judicial behavior and the significant work of Barry Friedman, Jeffrey Rosen, and others who link Supreme Court decision making to public opinion.

Jennifer Higdon's Oboe Concerto: The Composition, Transformation, And A Performer's Analysis, Janice Elizabeth Crews

LSU Doctoral Dissertations

This monograph presents a formal examination of Jennifer Higdon’s Oboe Concerto in its various forms. Jennifer Higdon has garnered international success, yet few in-depth studies of her music exist. In this document, personal accounts from commissioners illustrate the unusual commission of Oboe Concerto. Likewise, the composer, a conductor, and soloists for premiere performances highlight unique aspects of the concerto, particularly its unusual form, multiple versions, and the potential challenges in preparing the work. Higdon’s concerto showcases the lyrical capabilities of the oboe, with an emphasis on melody and sustained tone. The transformation of the concerto illustrates Higdon’s skills of self-promotion, …

Model-Based Nonlinear Control Of Active Tilting-Pad Bearings, An Wu

LSU Doctoral Dissertations

A promising mechanical bearing candidate for active operation is the tilting-pad bearing. The proposed active tilting-pad bearing has linear actuators that radially translate each pad. The use of feedback control in determining the actuator forces allows for the automatic, continuous adjustment of the pad position during the operation of the rotating machine. In the first part of the dissertation, we develop a nonlinear dynamic model of the active bearing system. The hydrodynamic force produced by the fluid film is modeled as a nonlinear, squeeze-film damper plus repellent spring. A model-based nonlinear controller is then designed to exponentially regulate the rotor …

More Than Words, More Than Wounds: (Re)Writing 'Wounded' Women And Healing Pedagogies, Rachel Nicole Spear

LSU Doctoral Dissertations

This project reconceptualizes how women and their personal stories of trauma have been read and represented in literary, feminist, and pedagogical studies, asserting that these authors and their texts should be recognized respectively as wounded healers and healing narratives. By situating my study within links among trauma, women, and writing, I argue that women and their personal stories of trauma exist in marginal, or rather, wounded positions. I problematize scholarship where links among these three commonly emerge (namely psychoanalytic, autobiographical, and feminist fields) to challenge monolithic readings and re-write these women and texts as more than wounded. More than Words, …

Task And Relationship Conflict In Subordinates And Supervisors Relations: Interaction Effects Of Justice Perceptions And Emotion Management, Sungwon Choi

LSU Doctoral Dissertations

This dissertation investigates the antecedents and outcomes of task and relationship conflict in subordinates and supervisors relations. Based on abusive supervision studies and the justice framework, I proposed that the relationship between abusive supervision and task conflict is mediated by procedural justice, and that the relationship between abusive supervision and relationship conflict is mediated by interactional justice. Based on emotional intelligence theory, I also proposed that these mediation processes are moderated by an individual’s emotion management ability (EMA). Finally, I anticipated that relationship conflict elicits more detrimental effect on employees’ organizational citizenship and workplace deviance behaviors. A total of 310 …

Investigations Of Structure / Property Interrelationships Of Organic Thin Films Using Scanning Probe Microscopy And Nanolithography, Zorabel Mallorca Lejeune

LSU Doctoral Dissertations

Studies of the surface assembly and molecular organization of organic thin films were studied using scanning probe microscopy (SPM) and scanning probe lithography (SPL). Systems of organic thin films such as n-alkanethiols and pyridyl functionalized porphyrins were characterized at the molecular level, and measurements of the conductive properties of polythiophenes containing in-chain cobaltabisdicarbollides were accomplished. Understanding the self-organization and mechanisms of self-assembly of organic molecules provides fundamental insight for structure/property interrelationships. Investigations of the surface assembly of 5,10-diphenyl-15,20-di-pyridin-4-yl-porphyrin (DPP) on Au(111) were done using SPL methods of nanoshaving and nanografting. Automated computer designs were developed for nanofabrication to provide local …

Cross-Race Advising Relationships: The Role Of Race In Advising Relationships Between Black Doctoral Student Protégés And Their White Faculty Advisors, Marco Javon Barker

LSU Doctoral Dissertations

The purpose of this phenomenological study was to examine the role of race in cross-race advising relationships between White faculty advisors and their Black doctoral student protégés. I examined the racial context of doctoral education experiences and relationships between doctoral students and faculty. Blacks with doctoral degrees comprise only 0.3% of those 18 years and older and only 3.5% of those with doctoral degrees (U.S. Census, 2000). Although there has been an increase in the number of Blacks enrolling in doctoral programs (Cook & Cordova, 2006), Nettles and Millett (2006) found that Blacks and Latin Americans have higher attrition rates …

"Blessed Be The Critics Of Newspapers": Journalistic Criticism Of Journalism 1865-1930, Yasmine Tarek Dabbous

LSU Doctoral Dissertations

This study examined journalistic press criticism between 1865 and 1930. It sought to understand how the first modern journalists conceived of their profession in a period of great transitions. As the study revealed, journalists writing about journalism between 1865 and 1930 discussed recurring themes such as commercialization, sensationalism, advertising, and ethics. They expressed ambivalence toward the rise of big business in their field and the consequences it could have on the quality of the work. In the process, journalists also defined journalism as a profession providing a public service or as a business aiming solely for circulation and profit. Definitions …

Three Essays On The Role Of Amenities As An Economic Development Strategy, Junpyo Hong

LSU Doctoral Dissertations

It is well known that an amenity is a key driving engine to regional economic growth. However, the site-specific nature of an amenity can characterize them as public goods. Due to this characteristic, local governments have difficulty optimally supplying amenities. This dissertation tries to find relationships between an amenity and economic growth. Three empirical papers comprise the original research in this dissertation. The findings of the meta-analysis in the first essay suggest little methodological diversity exists among researchers linking amenities to economic growth., I do find that employment growth is more likely related to man-made amenities even in research on …

The Achievement Of Business Education Students On High School Core Subjects, Mohd Khata Bin Jabor

LSU Doctoral Dissertations

The importance of academic courses taken during high school has been well documented. It could determine the students’ achievement in high school, affect the students’ ability to transition to postsecondary education and expand the students’ choice of postsecondary majors and degree options (Laird, Chen, & Levesque, 2006). This study examined whether enrollment in business education is related to achievements in high school core subjects. The rationale for the study is to determine if business education contributes to the academic achievement of high school students. This study used the data from the National Assessment of Educational Progress (NAEP) High School Transcript …

The Effects Of Self-Assessment On Student Learning Of Mathematics, Daniel James Hotard

LSU Master's Theses

Self-assessment can be defined as students judging their own work, based on evidence and explicit criteria, for the purpose of improving future performance. Many researchers agree that implementation of student self-assessment in the classroom is an important tool for improving academic performance and self-efficacy. In this thesis, I investigated the effects of student self-assessment on learning gains of 81 alternative high school Algebra I students. This study took place over the course of two units of instruction. Classes were divided into two groups. One group of students utilized rubrics to self-assess their own work for the first unit, while the …

The Effect Of War On Art: The Work Of Mark Rothko, Elizabeth Leigh Doland

LSU Master's Theses

My goal for this thesis was to adequately illustrate the effect war can have on art and artists. I chose to single out one particular artist who lived and worked during a time of war and explore his life and work. My choice of artist was not random: I chose an individual who was particularly concerned about his external environment, and was active in the political and social issues of the time. My subject is Mark Rothko, a Russian-Jewish artist who immigrated from Russia as a boy and spent his life in the hotspot of artistic inspiration, New York City. …

Stochastic Trends In Crop Yield Density Estimation, David I. Maradiaga

LSU Master's Theses

The search for improved methods of estimating crop yield density functions has been a theme of recurrent research interest in agricultural economics. Crop yield density functions are the statistical instrument that generates probability estimates of yield risk, and risk is an important decision variable in production agriculture. Recent research in crop yield density estimation suggests that yield probability estimates can be sensitive to the way yield data are filtered, and if true, then the search for an “adequate filter” is warranted. Such a quest is pursued in this study. It is proposed that unit-root tests can be used to identify …

Depolarization By Transient Receptor Potential Melastatin 4 In Pancreatic Alpha-Cells Regulates Glucagon Secretion, Piper Lynn Nelson

LSU Master's Theses

The Transient Receptor Potential Melastatin 4 protein (TRPM4) is a member of the TRP family of ion channels that is expressed in both electrically excitable and non-excitable cells. Functional studies revealed that TRPM4 significantly impacts Ca2+ signals in both immune and pancreatic β-cells, which is important for cellular processes such as hormone secretion. However, its role in glucagon secreting α-cells has not been reported. Type 2 Diabetes Mellitus is often associated with increased glucagon levels; yet, the exact mechanism controlling its secretion is not known. In pancreatic α-cells, an increase in intracellular Ca2+ concentration causes glucagon secretion. We hypothesize that …

Detect Live Salmonella Cells In Produce By Coupling Propidium Monoazide With Loop-Mediated Isothermal Amplification (Pma-Lamp), Siyi Chen

LSU Master's Theses

Salmonella is a leading cause of foodborne illnesses worldwide. In recent years, an increasing number of Salmonella-related outbreaks in produce has been reported. It is therefore important that the produce industry be equipped with rapid, sensitive, specific detection methods for live Salmonella cells in produce to better ensure the produce safety. In this study, we first designed and optimized a loop-mediated isothermal amplification (LAMP) assay for Salmonella detection by targeting the invasion gene (invA). Then we incorporated a chemical reagent, propidium monoazide (PMA) into the sample preparation step to prevent LAMP amplification of dead Salmonella cells. To our knowledge, this …

Application Of Peer Instruction In The High School Setting, Wiley Iverstine

LSU Master's Theses

This study investigates whether the response component of Peer Instruction can be successfully added to my normal classroom instruction creating higher gains in student conceptual understanding of force concepts. This action research is intended to analyze this goal for possible application in any regular high school Physics classroom, using myself as a case study. The Force Concept Inventory was used as a pretest/posttest determinate of the learning gains of 85 students spread through four regular Physics classes during the 2009-10 school year. Forty-Two of these students were used as an experimental group where the response component of Peer Instruction was …

The Relationship Among Self-Efficacy, Negative Self-Statements, And Social Anxiety In Children: A Mediation, Brittany Nicole Moree

LSU Master's Theses

Evidence suggests that general self-efficacy, one’s beliefs about his or her global abilities, and social self-efficacy, one’s beliefs in his or her ability to navigate social situations, are strongly connected to levels of social anxiety. Negative self-statements, also known as negative self-referent cognitions, have also been linked with levels of social anxiety. Although self-efficacy and negative self-statements have been shown to be important variables in the phenomenology and maintenance of social anxiety in children, they have yet to be examined in conjunction with one another. The purpose of this study was to examine the relationship between negative self-statements and selfefficacy …

Itraconazole Loaded Poly (Lactic-Co-Glycolic) Acid Nanoparticles For Improved Antifungal Activity, Nipur Rajan Patel

LSU Master's Theses

PLGA (polylactic-co-glycolic acid) nanoparticles containing the hydrophobic antifungal Itraconazole (ITZ) were developed to address the need for more efficient means of treating fungal infections. PLGA-ITZ nanoparticles were synthesized using an oil-in-water emulsion evaporation method. The nanoparticles morphology (TEM), size and size distribution, zeta potential (DLS), encapsulation efficiency (UV-VIS), release profile, and antifungal activity were characterized. The blank NPs and loaded PLGA-ITZ NPs were spherical with diameters of 201±5 nm, 232±1 nm and 223±36 nm at 0%, 12.5% and 25% loadings, respectively. All synthesized particles measured a negative zeta potential ranging from -28 to -33 mV. The maximum encapsulation efficiency of …

Dry Event Trends And Frequencies In The South Central United States, Michael Roberts

LSU Master's Theses

In this study, dry spells in the southern United States are analyzed. Dry spells are defined as consecutive days with no recorded rainfall. Seventy (70) weather stations are researched in Texas, Oklahoma, Louisiana, Arkansas, Mississippi, and Tennessee. Daily precipitation for each station identifies potential trends in consecutive dry days. Stations were selected for their completeness, longevity, and their proximity to one another. Only stations with five percent or less missing data were allowed. All 70 stations will be analyzed from 1950-2008. Twenty-four stations possess over 100 years of data and will be analyzed. The best geographical indicator for consecutive dry …

Collaboration Via Wikis: Social Aspects And Adapting Teacher Feedback In An Online Environment, Madeline Boudreaux

LSU Master's Theses

The primary goal of this thesis is to investigate the way in which learners interact when asked to work together to write and revise a composition in an online environment. Specifically, the first research question explores the working styles of learners in the context of a wiki. It seeks to determine whether the various dyads work collaboratively or cooperatively to write and revise a composition in Spanish. The second research question deals with the type and degree of politeness that students express towards each other when working together to write and revise their composition. Specifically, it investigates the nature of …
