Inside The Red Box: North Korea's Post-Totalitarian Politcs, Patrick Mceachern Jan 2009

Inside The Red Box: North Korea's Post-Totalitarian Politcs, Patrick Mceachern

LSU Doctoral Dissertations

This dissertation proposes a radically new understanding of North Korean politics under Kim Jong Il and carefully tests this theoretical proposition. Current models describe North Korea as some form of a highly centralized state: totalitarian, personalistic, or corporatist. By contrast, I argue that these monolithic ideal types fail to capture the institutional pluralism that helps distinguish the younger Kim’s rein from his father’s. While Kim Il Sung’s rule can be described as totalitarian, Kim Jong Il governs through a more decentralized post-totalitarian, institutionally plural state. Kim Jong Il’s government is highly centralized, but it is less centralized than his father’s. …

Assessment Of Target Purity Difference For A Louisiana Sugar Mill, Luz Stella Polanco Jan 2009

Assessment Of Target Purity Difference For A Louisiana Sugar Mill, Luz Stella Polanco

LSU Master's Theses

The main goals of a “raw” sugarcane factory are to have an efficient profitable operation with the required sugar quality and maximum sugar recovery. The loss of sugar to final molasses accounts for 45 to 47% of the total sugar losses. An estimation of the average cost of the manufacturing losses for the 2007 harvest season was approximately $9 million – the sugar lost to the final molasses accounts for approximately 50% of this cost (Salassi, 2008). For final molasses, the “Target Purity” (or equilibrium purity) refers to the minimum level of sucrose that theoretically remains in solution for a …

A Comparison Of Foreign News Coverage In The Mercantile And Popular Press Of The 1830s, Virgil Ian Stanford Jan 2009

A Comparison Of Foreign News Coverage In The Mercantile And Popular Press Of The 1830s, Virgil Ian Stanford

LSU Master's Theses

The rise of the American penny press in the 1830s is thought of as a crucial moment in journalism history that precipitated changes in newspapers that are still evident today. Yet, many specific characteristics of the transition from a predominantly elite mercantile and partisan press to the popular penny press remain unknown, including the changes that occurred in foreign news coverage. This study will examine four newspapers, two mercantile and two penny, printed in New York City from 1830 to 1842. It will use quantitative content analysis of five variables – frequency, length, prominence, content, and presentation style – to …

The Assessment Of And Differences Among Intellectually Disabled Adults With Comorbid Autism Spectrum Disorders And Epilepsy, Kimberly Robin Michelle Smith

LSU Doctoral Dissertations

The goal of this study was to systematically examine group differences among those with intellectual disabilities (ID) and comorbid Autism Spectrum Disorders (ASD) and epilepsy in an adult population through a detailed exploration of the characteristics that these disorders present in the areas of psychopathology, behavior problems, and impaired social behavior. Previous studies indicating that individuals with ID have comorbid ASD and neurological conditions tend to stop short of addressing these disorders’ impact on the full range of psychosocial issues, particularly in adult samples. Assessments of psychopathology, behavior problems, and impaired social behavior were made with the ASD-Comorbidity-Adult Version and …

Development Of A Rapid And Effective Screening Method For Basal Stress Tolerance Of Petunia X Hybrida, Miao Liu Jan 2009

Development Of A Rapid And Effective Screening Method For Basal Stress Tolerance Of Petunia X Hybrida, Miao Liu

LSU Master's Theses

High temperature and drought stress are two of the greatest impediments to bedding plant growth and development. The objective of this study was to develop a rapid and effective protocol for screening Petunia x hybrida for basal heat or drought tolerance. A practical growth system for measuring seedling growth, or seedling growth sensitivity test (SGST), was first established. Based on this protocol, radicle growth rate was chosen over hypocotyl growth as the most reliable and accurate measurement for the SGST. Nineteen petunia cultivars from three plant classes (floribunda, grandiflora, or spreading) were previously evaluated, where cultivars within the same plant …

Quantum Nonlinear Optics: Applications To Quantum Metrology, Imaging, And Information, Ryan Glasser Jan 2009

Quantum Nonlinear Optics: Applications To Quantum Metrology, Imaging, And Information, Ryan Glasser

LSU Doctoral Dissertations

The fields of quantum and nonlinear optics have given rise to a variety of nonclassical states of light that have been proven to surpass certain limitations set by classical physics. Namely, certain squeezed and entangled states have been shown to beat the shot-noise limit when making precision phase measurements in interferometry, as well as write lithographic patterns that are smaller than classically allowed by the Rayleigh diffraction limit. Additionally, single-photon sources and entangled photon pairs have given rise to provably secure quantum key distribution for cryptography. Producing these quantum states of light has proven a difficult task. Nonlinear crystals, when …

The Pasquale Amato Correspondence At Louisiana State University, Sarah Wells Kaufman Jan 2009

The Pasquale Amato Correspondence At Louisiana State University, Sarah Wells Kaufman

LSU Master's Theses

Italian baritone Pasquale Amato (1878-1942), who sang at the Metropolitan Opera in New York from 1908–1921, was regarded by critics and colleagues as a leading baritone of the early twentieth-century. Amato appeared in several United States and world premieres, most notably as Jack Rance in Giacomo Pucinni’s La fanciulla del West (1910), and often performed alongside Enrico Caruso. After leaving the Met in 1921 and touring Europe until 1926, Amato returned to the United States. His struggle to find substantial work eventually led to his pursuing teaching. In 1935, having secured a position as director of the opera department at …

Nanoidentation Behavior Of Clay Minerals And Clay-Based Nonstructured Multilayers, Zhongxin Wei Jan 2009

Nanoidentation Behavior Of Clay Minerals And Clay-Based Nonstructured Multilayers, Zhongxin Wei

LSU Doctoral Dissertations

Clay minerals, ubiquitous in the geosphere, are hydrous layered silicates or phyllosilicates that are made of nanometer-thick 2:1 or 1:1 layers. Understanding their mechanical properties of clay minerals is of vital importance to a variety of disciplines, such as geomechanics, geophysics, mineral physics, and nanocomposites. Owing to their complex crystal structure and size, however, accurate determination of their mechanical properties is a significant challenge. This dissertation presents the first research effort to study systematically the fundamental mechanical properties along the c-axis (e.g., elastic modulus, hardness) of a wide range of phyllosilicates with varying crystal structure and chemical compositions. To explore …

An Analysis Of The Historical And Biographical Influences On The Music Of Francis Poulenc As Portrayed In His Les Soirées De Nazelles, Gay K. Grosz Jan 2009

An Analysis Of The Historical And Biographical Influences On The Music Of Francis Poulenc As Portrayed In His Les Soirées De Nazelles, Gay K. Grosz

LSU Doctoral Dissertations

As a composer, Francis Poulenc has been under-appreciated and overlooked by many contemporary performers and teachers. Poulenc wrote music from his heart, paying little heed to formal systems or musical fashions of his day. In matters of harmony, he was content to use conventional chromatic harmony, but in a manner uniquely his own. Poulenc’s compositions always reflected his personality and Les Soirées de Nazelles is no exception. The many facets of Poulenc’s personality cannot be separated from his music and they contribute to its wit and charm. This document is an examination of Poulenc’s background, personality, and influences, and how …

Memory For Music And The Implications Of Expertise For Music Recall: A Review ; Memory For The Recall Of Popular Songs: A Comparative Study Of Musicians And Nonmusicians, Simon Maclachlan Jan 2009

Memory For Music And The Implications Of Expertise For Music Recall: A Review ; Memory For The Recall Of Popular Songs: A Comparative Study Of Musicians And Nonmusicians, Simon Maclachlan

Theses : Honours

How people remember music is not only a practical concern for musicians, it also poses an interesting challenge for psychological theory (Wallace, 1994). One question that has often been overlooked is what occurs during the time that elapses between the stimulus onset (hearing music) and the generation of a response (an indication that the song has been remembered). While there is evidence to show that memory for song may be biased in a forward direction (Sibma, 2003), the role of expertise on memory for song may provide a deeper understanding of the nature of our memory for music. This review …

Reasons For Migration And Cultural Distance In South African Women's Migratory Adjustment Experiences: A Phenomenological Account, Ida Steyn Jan 2009

Reasons For Migration And Cultural Distance In South African Women's Migratory Adjustment Experiences: A Phenomenological Account, Ida Steyn

Theses : Honours

Researchers have identified migration to a new country as a stressful life event that is associated with loss of family, friends and community, and adjustment difficulties in the new country (Markovizky & Samid, 2008). In addition, involuntary migration and adaption to a new cultural environment is known to be a factor of psychological distress. Much is unknown about the adjustment of involuntary migrants during the critical period of reestablishment in the new environment. Moreover, less is known about transition processes between similar cultural contexts. It might be that transition is not as well supported when there is cultural similarity between …

The Role Of Resilience In Second Year University Students, Sarah M. Barbas Jan 2009

The Role Of Resilience In Second Year University Students, Sarah M. Barbas

Theses : Honours

Around one third of all first year University students will not continue their studies in second year. Students who incur difficulties transitioning from one context to another have been found to withdraw due to an inability to cope with the challenges and adversity in their new environment. On the other hand, many students are able to effectively overcome significant difficulties they are faced with during the transition to or through university. This concept may be referred to as resilience. Few studies have investigated the role of resilience in the success of university students with no research currently focusing on second …

The Relationship Between Working Memory Capacity And Movement Memory Of Dancers, Katrina Louise Muller-Townsend Jan 2009

The Relationship Between Working Memory Capacity And Movement Memory Of Dancers, Katrina Louise Muller-Townsend

Theses : Honours

Working memory capacity span tasks are suggested to predict complex cognitive behaviour across varied domains (Conway et al., 2005). However, it has been criticised that expert skills are highly situational and domain specific (Marteniuk, 1974). The current research aimed to investigate whether general memory span was related to movement span, and furthermore, whether this can predict dance learning. It was expected that memory for movement would be positively correlated with measures of working memory, due to the specific components of working memory, such as the capacity of the phonological loop. Furthermore, it was expected on the basis of previous research …

Attitudes Toward Asylum Seekers: The Role Of Beliefs In Procedural Fairness, Lisa Palamountain Jan 2009

Attitudes Toward Asylum Seekers: The Role Of Beliefs In Procedural Fairness, Lisa Palamountain

Theses : Honours

This study investigated the relationship between beliefs in procedural fairness, humanitarian values, and attitudes toward asylum seekers amongst a sample of first year university students in Western Australia (N = 148). Beliefs in procedural fairness were measured in terms of beliefs in the fairness of decision making and beliefs in the fairness of treatment. Findings supported the hypotheses, in that beliefs in procedural fairness were significantly related to attitudes and humanitarian values. Regression analyses revealed that beliefs in the fairness of treatment and humanitarian values made unique contributions in predicting attitudes. However beliefs in the fairness of decision making did …

Anglo-Australians' Attitudes Towards Asylum Seekers And Egalitarianism, Antonietta Matrone Faulkner Jan 2009

Anglo-Australians' Attitudes Towards Asylum Seekers And Egalitarianism, Antonietta Matrone Faulkner

Theses : Honours

Research has found that generally Australians hold negative attitudes towards asylum seekers. These negative attitudes appear to be influenced by perceptions of threat and false beliefs. The current study explored the attitudes of Anglo-Australians towards asylum seekers and how attitudes are related to the concept of Australian egalitarianism and fair go. Twelve semi-structured interviews were conducted for this study. Three main themes were identified through thematic content analysis: characterising asylum seekers, responses to asylum seekers in Australia, and constructing fairness.' Characterising asylum seekers represented the informants' constructs of asylum seekers as being genuine asylum seekers, or boat people …

An Investigation Into Student Reactions Towards Rad Versus Traditional Programming Environments For Novice Developers, Pansy Colkers Jan 2009

An Investigation Into Student Reactions Towards Rad Versus Traditional Programming Environments For Novice Developers, Pansy Colkers

Theses : Honours

The traditional approach to programming using text editors is widely used in many institutions to teach introductory programming. These types of traditional programming environments provide fundamental programming concepts for learning, especially in the context of novice developers. In recent years, teaching institutions have seen a trend towards the introduction of visual "drag-and-drop" rapid application development (RAD) environments for teaching novice programmers. These 'environments capture student interest in programming by allowing the construction of workable programs within a short time frame based on minimal pre-existing coding knowledge. However, some have argued that these visual RAD environments might not be suitable for …
