The Electoral Costs Of Party Agenda Setting: Why The Hastert Rule Leads To Defeat, Jesse Richman Jan 2015

The Electoral Costs Of Party Agenda Setting: Why The Hastert Rule Leads To Defeat, Jesse Richman

Political Science & Geography Faculty Publications

This study demonstrates that unconditional blocking of bills opposed by a majority of the majority party--as implied by the party cartel model and advocated by former Speaker Dennis Hastert--can produce conditions in which the majority party loses popular support and loses elections. The theoretical analysis and empirical results imply that the use of negative agenda power to block bills is circumscribed by this risk of electoral defeat. As a result, the opportunity for effective negative agenda control is conditional on majority party issue advantage, party polarization, and the distribution of status quo locations. In particular, majority party roll rates should …

Booker T. Washington And The Historians: How Changing Views On Race Relations, Economics, And Education Shaped Washington Historiography, 1915-2010, Joshua Thomas Zeringue Jan 2015

Booker T. Washington And The Historians: How Changing Views On Race Relations, Economics, And Education Shaped Washington Historiography, 1915-2010, Joshua Thomas Zeringue

LSU Master's Theses

“Booker T. Washington and the Historians” analyzes the past century of scholarly writings on Booker T. Washington and seeks to describe the major paradigms used to explain his life and work. Between 1915 and 2010 four major paradigms emerged. The hagiographic paradigm, which offered an uncritical and triumphal account, dominated Washington scholarship from 1915 to 1950. In the 1950s the critical paradigm became widely accepted among historians; Washington was viewed as a compromiser with white supremacists and Northern industrialists. In the 1990s and 2000s the educational paradigm, which focused on Washington’s pedagogy and educational achievements, developed as an alternative to …

An Exploration Of Plasmonics For Nanoparticle-Based Gene Delivery, Corey Raymond Landry Jan 2015

An Exploration Of Plasmonics For Nanoparticle-Based Gene Delivery, Corey Raymond Landry

LSU Master's Theses

The spatiotemporal control of biological processes, especially cell growth and differentiation, remains one of the most compelling challenges in basic and clinical biomedical research. Fields as diverse as cancer therapy and regenerative medicine rely on spatial and temporal control of biochemical cues to achieve desired biological objectives. MicroRNA are attractive for highly-localized delivery applications because their instability in the cell restricts their biological effect to a small target area. These short, non-coding strands can be easily synthesized and modified for attachment and release from nanoparticle delivery vehicles. The research interest around microRNA therapies has produced a wide array of pathways …

Nationalization And Regionalism In 1920s College Football, Bennett Jeffery Koerber Jan 2015

Nationalization And Regionalism In 1920s College Football, Bennett Jeffery Koerber

LSU Master's Theses

By illuminating the complexities of 1920s American society, college football serves as a remarkably insightful cultural device. At the commencement of the decade, a national business community – one that had been developing since the late nineteenth century – appeared to have come to fruition. The more connected nature of the country served to homogenize the United States economically, politically, and even socially. Citizens who had once lived autonomously found themselves more interconnected with neighboring regions of the country, and thus increasingly defined by national characteristics. This served as an internal crisis of sorts because regional identity operated as a …

This Is My Attempt To Hold On, Kimberly Reneé Jones

LSU Master's Theses

I am an identical twin. The connection I share with my twin sister is intense and immediate. But now, we live over 800 miles apart. This Is My Attempt To Hold On serves as a visual metaphor for the longing for the undiluted rapport we have when we are together, and the frustrations of communicating with her through a digital device. I am constantly dissatisfied with my attempts to connect with her. I watch myself, my words, and my thoughts become diffused through the pixels. The work exists as composites of various mediums, creating a dialogue between photography, printmaking, sculpture, …

Reporting For The State Department: Carl W. Ackerman's Cooperation With Government During Wwi, Meghan Elizabeth Menard Jan 2015

Reporting For The State Department: Carl W. Ackerman's Cooperation With Government During Wwi, Meghan Elizabeth Menard

LSU Master's Theses

The press was outraged when reports in 1973 exposed the CIA’s use of American journalists as undercover informants during the Cold War. The CIA-journalists link represented for the press a shocking break in the traditional line between journalists and government. A study of journalist Carl W. Ackerman’s experiences in the First World War suggests, however, that the CIA-journalists link has historical precedents in the practices of twentieth-century reporters. Ackerman, who later became the first dean of Columbia Journalism School, sent confidential reports to the State Department while reporting overseas for magazines and newspapers. He forged close relationships with a number …

An Efficient Fault Location Algorithm For Shipboard Power Systems, Pedram Jahanmard Jan 2015

An Efficient Fault Location Algorithm For Shipboard Power Systems, Pedram Jahanmard

LSU Master's Theses

The Shipboard Power System (SPS) supply energy to sophisticated systems for navigation, communication, weapons, and operation. Due to the ship’s critical operating condition, faults can be very detrimental. Faults in the SPS may happen because of failure of electrical components or by damages that happen during a battle. These faults may interrupt the paths for supplying energy to loads that are not damaged. To enhance survivability of naval ships, SPS requires an efficient fault location algorithm in order to locate and clear the fault as well as provide an alternative path to supply energy to the loads that are not …

Metacommunity Dynamics And The Biogeography Of Central Louisiana Crayfishes, William Robert Budnick Jan 2015

Metacommunity Dynamics And The Biogeography Of Central Louisiana Crayfishes, William Robert Budnick

LSU Master's Theses

The greatest diversity of crayfishes, especially of rare Orconectes species, is found in the central Louisiana watersheds (Red River, Mermentau, Calcasieu, and Vermillion-Teche), and most species are widely distributed among the drainages. The purpose of this research was to lay groundwork for species distribution and metacommunity modelling for crayfishes in this region. To address this goal, two field studies were performed in the summers of 2013 and 2014, as well as an indoor laboratory study. Analyses of broadly distributed species indicated no significant correlations between species abundances and habitat variables nor any significant environmental gradients for those species. Within-drainage variability …

Active Versus Passive Control Of Arm Swing: Implication Of The Restriction Of Pelvis Rotation During Human Locomotion, Stephen Paul Canton Jan 2015

Active Versus Passive Control Of Arm Swing: Implication Of The Restriction Of Pelvis Rotation During Human Locomotion, Stephen Paul Canton

LSU Master's Theses

To date, it remains unclear how passive dynamics and active neural control contribute to arm swing during human locomotion. The passive hypothesis attributes arm swing to the passive transfer of energy from the legs to the arms via biomechanical linkages, while the active hypothesis states that arm swing is actively driven by muscles via neural mechanisms. The present study aims to investigate this phenomenon further by disrupting the biomechanical linkages, thereby directly challenging the passive hypothesis. Ten healthy individuals walked on a treadmill with and without an apparatus that constrained pelvis rotation at 3 different speeds (2 mph, 3 mph, …

Sexual Dimorphism In The Crania In A Norwegian Sample, Tonje Bakke Noack

LSU Master's Theses

Physical anthropologists strive to improve the accuracy of sex identification and to establish criteria of measurements within various populations. Different groups of native inhabitants show dissimilar results within cranial measurements and inaccuracies have been confirmed when comparing all populations to the common standard lineal measurements. This research examined 24 measurements on 120 crania from Norway and used statistical analyses to determine the sexual dimorphism between male and female crania. The study established the measurements with the most sexual dimorphism. These are the measurements of bizygomatic breadth, basion-bregma, biauricular breadth, glabella-opisthocranion, and upper facial breadth. The similarity of the values of …

Informal Landscape Architecture: A Tool To Improve Water Quality For Informal Settlements Along Waterways In Bangkok, Jidapa Chayakul Jan 2015

Informal Landscape Architecture: A Tool To Improve Water Quality For Informal Settlements Along Waterways In Bangkok, Jidapa Chayakul

LSU Master's Theses

The canals of Bangkok were a vital form of infrastructure from when the city was founded in 1782 until the 1850s, when the road system was introduced. Built for agricultural irrigation, the canals served as the primary means of transportation and significantly influenced the form and orientation of Bangkok’s early settlements and public institutions. With the implementation of roads, new buildings were constructed to be oriented towards the streets and away from the canals. The canals and their communities subsequently decreased in visibility. Today, most of the land along the waterways is publically owned. As a result, the land adjacent …

How Local Nonprofit Organizations Can Use Narratives To Build Organizational-Public Relationships On Digital Media, Ryan Patrick Delaune Jan 2015

How Local Nonprofit Organizations Can Use Narratives To Build Organizational-Public Relationships On Digital Media, Ryan Patrick Delaune

LSU Master's Theses

The nonprofit sector’s adaptation and implementation of digital media is one that has received surprisingly little exploration. While some research has been conducted in this area, these studies tend to generalize results across all organization types within the nonprofit sector. Often, these studies overlook specific advantages nonprofits of varying types, sizes, and locations may potentially have in regard to fostering relationships with their communities. This study explores how these differences may impact organizational use of digital media, and how organizations can potentially use these media to more efficiently achieve their goals. Specifically, this study focuses on the use of narratives …
