Putting A Face On Prehistory: Reconstructing Late-Mississippian Faces, Alicia Canfield Jan 2009

Putting A Face On Prehistory: Reconstructing Late-Mississippian Faces, Alicia Canfield

LSU Master's Theses

This paper examines the results of artificial cranial deformation on the human skull in relation to the human face and the use of three-dimensional printing in the making of skull casts. Forensic facial reconstructions, following the American Method, were performed on three Native American skulls from the Late-Mississippian period, excavated from the Humber Site and on loan from the University of Southern Mississippi, in order to see whether or not the artificial deformation radically changed the faces of the individuals. Skull casts were made out of ABS plastic using rapid prototyping technology, as the original skulls were too fragile for …

Atomistic Simulations Of Lipid Bilayers In The Presence Of Dimethylsulfoxide, Raghava Alapati

LSU Master's Theses

In a typical cryopreservation protocol, the system to be preserved is first equilibrated with chemicals known as cryoprotective agents (CPAs). CPAs have been shown to alleviate cell damage from either the solute effects or the formation of intracellular ice during the subsequent freezing process. Thus, an extensive body of literature reporting the effects of CPAs on cellular systems has been accumulated over the last 50 years; detailing largely experimental interactions between cell systems and chemicals. Recent advances in computational methodology now offer an additional dimension in our ability to understand the molecular interactions between cell membranes, idealized as lipid bilayers …

Land Use Based Crime Rates: Exploring Patterns Of Land Use And Crime Rates In Coquitlam And Port Coquitlam, Kathryn Wuschke Jan 2009

Land Use Based Crime Rates: Exploring Patterns Of Land Use And Crime Rates In Coquitlam And Port Coquitlam, Kathryn Wuschke

Criminology and Criminal Justice Faculty Publications and Presentations

While it is certainly valuable to understand the counts of specific crime types by location, in order to contextualize the relationships between these features, rates are needed. Table 1 further explores this relationship by calculating the rate of each crime by land use. While rates are often employed using population as a denominator, such a measure is not practical when exploring crime at the parcel level. In this case, rates have been calculated according to crimes per 100 lots, producing an understandable and comparable value across all categories of land use and crime.

Platforms And Protocols For The Multidimensional Microchip Electrophoretic Analysis Of Complex Proteomes, John K. Osiri Jan 2009

Platforms And Protocols For The Multidimensional Microchip Electrophoretic Analysis Of Complex Proteomes, John K. Osiri

LSU Doctoral Dissertations

The need for rapid, portable and high-throughput systems in proteomics is now prevalent because of demands for generating new protein-based disease biomarkers. However, 2-D protein profile patterns are lending themselves as potential diagnostic tools for biomarker discovery. It is difficult to identify protein biomarkers which are low abundant in the presence of highly abundant proteins, especially in complex biological samples like serum. Protein profiles from 2-D separation of the protein content of cells or body fluids, which are unique to certain physiological or pathological states, are currently available on internet databases. In this work, we demonstrate the ability to separate …

Multiple Dataset Visualization (Mdv) Framework For Scalar Volume Data, Gaurav Khanduja Jan 2009

Multiple Dataset Visualization (Mdv) Framework For Scalar Volume Data, Gaurav Khanduja

LSU Doctoral Dissertations

Many applications require comparative analysis of multiple datasets representing different samples, conditions, time instants, or views in order to develop a better understanding of the scientific problem/system under consideration. One effective approach for such analysis is visualization of the data. In this PhD thesis, we propose an innovative multiple dataset visualization (MDV) approach in which two or more datasets of a given type are rendered concurrently in the same visualization. MDV is an important concept for the cases where it is not possible to make an inference based on one dataset, and comparisons between many datasets are required to reveal …

Do Tops Eligibility Requirements Predict In-System College Retention?, Jason J. Droddy Jan 2009

Do Tops Eligibility Requirements Predict In-System College Retention?, Jason J. Droddy

LSU Doctoral Dissertations

The Taylor Opportunity Program for Students (TOPS) is a state-funded, merit-based scholarship codified into Louisiana state law in 1997. More than $1 billion in awards have been distributed since the program’s inception. By 2006, eligibility for TOPS required a 2.5 high school grade point average on a legislatively specified 16.5-unit college preparatory curriculum, and a minimum ACT score equivalent to the average of the prior year’s test takers. These rules were believed to promote greater academic preparedness resulting in higher college retention rates. Only recently has the six-year graduation rate for Louisiana’s public universities passed the 30% mark. Since TOPS’ …

Solving The Employee Reference Problem: Lessons From The German Experience, Kenneth Glenn Dau-Schmidt, Matthew Finkin Jan 2009

Solving The Employee Reference Problem: Lessons From The German Experience, Kenneth Glenn Dau-Schmidt, Matthew Finkin

Articles by Maurer Faculty

In this article we examine the problem of declining employer references in the American economy. We argue that the problem is not that employers inordinately fear potential slander and libel liability for giving references, but that they have no assurance of benefits from reciprocal references in exchange for taking any risk or suffering any cost in giving references. We provide a comparative legal analysis and argue that the United States might benefit from adopting an employer letter of recommendation system similar to that currently used in Germany.

Effects Of Network Capital And Social Support On Mental Health By Race And Class, Claire Norris Jan 2009

Effects Of Network Capital And Social Support On Mental Health By Race And Class, Claire Norris

LSU Doctoral Dissertations

This study investigates race and class differences in the stress-support-distress process. Incorporating the social support strand of network analysis in the stress-support-distress model allows social support theorists to understand better what network sectors enhance/restrict access to such resources as social support and, in turn, affect such outcomes as mental health. I used data collected in a 2003 study of residents in Orleans Parish, Louisiana, to construct measures used in my analyses. Using independent samples t-test and ordinary least squares regressions, I addressed five general research questions: (1) whether and how there are variations in network capital forms – the structure …

Psychopathology In Person With And Without Co-Morbid Autism, Martin Nicholas Ancona Jan 2009

Psychopathology In Person With And Without Co-Morbid Autism, Martin Nicholas Ancona

LSU Doctoral Dissertations

Autism and intellectual disability are frequently co-occurring. In addition, a diagnosis of mild, moderate, severe, or profound intellectual disability increases the risk for co-occurring Axis I psychiatric disorders. This study utilized multivariate analyses of variance (MANOVA) to determine whether mean differences exist across three diagnostic groups: ID only, ID and autism, and ID and pervasive developmental disorder not otherwise specified (PDD-NOS) on the linear combination of subscales present on the Diagnostic Assessment of the Severely Handicapped-II (DASH-II), a psychometrically sound measure that assesses psychopathology in those with ID. The results of this study supported an association between the presence of …

U.S. Public Diplomacy Toward Iran: Structures, Actors, And Policy Communities, Foad Izadi Jan 2009

U.S. Public Diplomacy Toward Iran: Structures, Actors, And Policy Communities, Foad Izadi

LSU Doctoral Dissertations

This dissertation is an in depth study of the structures, actors, and policy communities associated with U.S. public diplomacy toward Iran. Since 2006, the U.S. government has spent more than $200 million for its Iran-related public diplomacy via State Department "democracy promotion" programs, National Endowment for Democracy, and the Broadcasting Board of Governors. These initiatives promoted regime change in Iran, ignoring a substantial majority of Iran’s population opposed to U.S.-sponsored interventions. The study finds U.S. public diplomacy as it relates to Iran fits with the two-way asymmetrical model of public relations. The dissertation identifies 182 individuals who participated in the …

Task Scheduling And Placement For Reconfigurable Devices, Mostafa Elbidweihy Jan 2009

Task Scheduling And Placement For Reconfigurable Devices, Mostafa Elbidweihy

LSU Doctoral Dissertations

Partially reconfigurable devices allow the execution of different tasks at the same time, removing tasks when they finish and inserting new tasks when they arrive. This dissertation investigates scheduling and placing real-time tasks (tasks with deadline) on reconfigurable devices. One basic scheduler is the First-Fit scheduler. By allowing the First-Fit scheduler to retry tasks while they can satisfy their deadlines, we found that its performance can be enhanced to be better than other schedulers. We also proposed a placement idea based on partitioning the reconfigurable area into regions of various widths, assigning a task to a region based on its …

Proxy Records Of Paleohurricanes For The Western And Southern Caribbean, Terrence Allen Mccloskey Jan 2009

Proxy Records Of Paleohurricanes For The Western And Southern Caribbean, Terrence Allen Mccloskey

LSU Doctoral Dissertations

This dissertation evaluates the hypothesis that hurricane activity levels in the North Atlantic during the late Holocene have been driven by latitudinal movements of the North Atlantic circulation system. Multi-millennial sedimentary proxy records, based on the occurrence of overwash clastic layers, provide clear evidence of abruptly alternating periods of hurricane landfall frequency for Nicaragua and Belize. Three Belizean transects exhibit an Active period (hyperactivity) occurring from ~2000-6000 cal yr BP, although dating is inconsistent across the transects. An Active period covering the last 500 years is found at one location. The Nicaraguan record, derived from three transects covering >90 km …
