Husserl's Phenomenological Reduction Revisited: An Attempt Of A Renewed Account, Sebastian Luft Jan 2004

Husserl's Phenomenological Reduction Revisited: An Attempt Of A Renewed Account, Sebastian Luft

Philosophy Faculty Research and Publications

This essay attempts a renewed, critical exposition of Husserl’s theory of the phenomenological reduction, incorporating manuscript material that has been published since the defining essays of the first generation of Husserl research. The discussion focuses on points that remain especially crucial, i. e. the concept of the natural attitude, the ways into the reduction, and the question of the “meaning of the reduction”. The reading attempted here leads to two, not necessarily related, focal points: a Cartesian and a Life-world tendency. In following these two paths, Husserl was consistent in pursuing two evident leads in his philosophical enterprise; however, he …

Husserl’S Theory Of The Phenomenological Reduction: Between Life-World And Cartesianism, Sebastian Luft Jan 2004

Husserl’S Theory Of The Phenomenological Reduction: Between Life-World And Cartesianism, Sebastian Luft

Philosophy Faculty Research and Publications

This essay attempts a renewed, critical exposition of Husserl's theory of the phenomenological reduction, incorporating manuscript material that has been published since the defining essays of the first generation of Husserl research. The discussion focuses on points that remain especially crucial, i.e., the concept of the natural attitude, the ways into the reduction (and their systematics), and finally the question of the "meaning of the reduction." Indeed, in the reading attempted here, this final question leads to two, not necessarily related, focal points: a Cartesian and a Life-world tendency. It is my claim that in following these two paths, Husserl …

Synthetic Landmine Scene Development And Validation In Dirsig, Erin D. Peterson Jan 2004

Synthetic Landmine Scene Development And Validation In Dirsig, Erin D. Peterson

Theses

Detection and neutralization of surface-laid and buried landmines has been a slow and dangerous endeavor for military forces and humanitarian organizations throughout the world. In an effort to make the process faster and safer, scientists have begun to exploit the ever-evolving passive electro-optical realm of detectors, both from a broadband perspective and a multi or hyperspectral perspective. Carried with this exploitation is the development of mine detection algorithms that take advantage of spectral features exhibited by mine targets, only available in a multi or hyperspectral data set. Difficulty in algorithm development arises from a lack of robust data, which is …

Dynamically Loaded Self-Aligning Journal Bearings: A Mobility Method Approach, Nathan Mayer Jan 2004

Dynamically Loaded Self-Aligning Journal Bearings: A Mobility Method Approach, Nathan Mayer

Theses

Journal bearings are a fundamental component in many pieces of machinery. A properly designed bearing is capable of supporting large loads in rotating systems with minimal frictional energy losses and virtually no wear even after years of services. These benefits make an understanding of dynamic behavior of these devices very valuable. In applications where journal bearings are subject to misalignment (conditions where the journal and sleeve axes are not parallel), it has long been understood that bearing performance can be compromised. To eliminate this problem, self-aligning bearings have been designed. The sleeves of these bearings are capable of moving freely …

Goal Directed Visual Search Based On Color Cues: Co-Operative Effectes Of Top-Down & Bottom-Up Visual Attention, Vishal S. Vaingankar Jan 2004

Goal Directed Visual Search Based On Color Cues: Co-Operative Effectes Of Top-Down & Bottom-Up Visual Attention, Vishal S. Vaingankar

Theses

Focus of Attention plays an important role in perception of the visual environment. Certain objects stand out in the scene irrespective of observers' goals. This form of attention capture, in which stimulus feature saliency captures our attention, is of a bottom-up nature. Often prior knowledge about objects and scenes can influence our attention. This form of attention capture, which is influenced by higher level knowledge about the objects, is called top-down attention. Top-down attention acts as a feedback mechanism for the feed-forward bottom-up attention. Visual search is a result of a combined effort of the top-down (cognitive cue) system and …

To Be Announced: Silence From The United States Supreme Court And Disagreement Among Lower Courts Suggest An Uncertain Future For Class-Wide Arbitration - Green Tree Fin. Corp. V. Bazzle, Jonathan R. Bunch

Journal of Dispute Resolution

With growth in the area of arbitration agreements relating to employment, credit cards, loans, and other form agreements, the issue of class-wide arbitration has become an area of significant judicial activity. However, increased judicial activity has not resulted in increased clarity; to the dismay of those parties seeking to pursue or avoid class-wide arbitration, the law on this issue has become unpredictable from jurisdiction to jurisdiction. The United States Supreme Court has expressed the importance of the class-action as a valuable device for vindicating plaintiffs' rights. Additionally, the Supreme Court has recognized arbitration as a valuable form of dispute resolution. …

Aquifer Denitrification : Correlation Of ¹⁵N Isotopic Enrichment And First-Order Rate Constants, Ryan Klapperich Jan 2004

Aquifer Denitrification : Correlation Of ¹⁵N Isotopic Enrichment And First-Order Rate Constants, Ryan Klapperich

Undergraduate Theses and Senior Projects

Denitrification is the process by which potentially dangerous nitrate is biogeochemically reduced into harmless nitrogen gas. This process is mediated by bacteria in the presence of suitable electron donors, such as organic carbon, sulfide, and ferrous iron. Due to its potential utility in the remediation of contaminated environments, the process of denitrification has received considerable attention. However, a relationship between the rate constant of the reaction and isotopic enrichment of 15N, which occurs as a direct result of the chemical reaction, has received little consideration. A strong correlation between these two factors could lead to a technique to estimate denitrification …

Assessing Landscape-Level Impacts Of Red Imported Fire Ants On Native Faunal Communities In Pine-Dominated Forests, Keri Elizabeth Landry Jan 2004

Assessing Landscape-Level Impacts Of Red Imported Fire Ants On Native Faunal Communities In Pine-Dominated Forests, Keri Elizabeth Landry

LSU Master's Theses

Since the accidental introduction of red imported fire ants (Solenopsis invicta Buren, RIFA) into Mobile, Alabama in the 1930’s, the invasion of this species into other areas across the southeast has increased drastically. RIFA have been implicated in the disruption of ecosystems and decreases in biodiversity. Most research on effects of RIFA on vertebrates and invertebrates have focused on small spatial scales and single species. I examined established populations of RIFA in relation to native ground-dwelling arthropods and small mammal communities in longleaf-pine and pine-hardwood forests. I evaluated the efficacy of using Amdro® to control RIFA and determined the effect …

Towards Automation Of Forensic Facial Reconstruction, Hemant Narendra Khatod Jan 2004

Towards Automation Of Forensic Facial Reconstruction, Hemant Narendra Khatod

LSU Master's Theses

Forensic facial reconstruction is a blend of art and science thus computerizing the process leads to numerous solutions. However, complete automation remains a challenge. This research concentrates on automating the first phase of forensic facial reconstruction which is automatic landmark detection by model fitting and extraction of feature points. Detection of landmarks is a challenging task since the skull orientation in a 3D scanned data cloud is generally arbitrary and unknown. To address the issue, well defined skull and mandible models with known geometric structure, features and orientation are (1) aligned and (2) fit to the scanned data. After model …

Durability Of Pine Strandboard Modified With Low Molecular Weight Phenol Formaldehyde, Matthew Daniel Voitier Jan 2004

Durability Of Pine Strandboard Modified With Low Molecular Weight Phenol Formaldehyde, Matthew Daniel Voitier

LSU Master's Theses

A continuing challenge for wood and wood-based composite building materials has been durability--the power of resisting agents or influences which tend to cause changes, decay, or dissolution; lastingness. In the case of wood-based products, this often requires a resistance to biological degradation and moisture related dimensional instability (particularly in particle and flake or strand boards). Borden Chemical Company has developed a new low molecular weight phenol formaldehyde additive, PD-112, to improve durability in composite wood products. This study investigated PD-112’s contribution to durability in oriented strand board (OSB) through laboratory testing of treated southern pine strandboard panels versus untreated control …

Mems Accelerometer: Proof Of Concept For Geotechnical Engineering Testing, Keith Nicholas Hoffman Jan 2004

Mems Accelerometer: Proof Of Concept For Geotechnical Engineering Testing, Keith Nicholas Hoffman

LSU Master's Theses

Geotechnical engineering materials are inherently variable, which leads to many simplifications when trying to model their behavior. The materials must always be characterized prior to any design work so that the engineer knows which direction he must progress to have a reliable design. Although subsurface characterization techniques and geotechnical design steadily improve, they are by no means infallible. The combination of geotechnical subsurface characterization along with geophysical techniques for improved design and construction monitoring has begun to surface as a viable alternative to the standard techniques in geotechnical engineering. This is important because there is a lack of Quality Control/Quality …

Microsatellite Instability In Squamous Cell Carcinoma And Lichen Sclerosus Of The Vulva, Sidney Joseph Marlborough Jan 2004

Microsatellite Instability In Squamous Cell Carcinoma And Lichen Sclerosus Of The Vulva, Sidney Joseph Marlborough

LSU Master's Theses

The usefulness of detecting genomic instability in the form of microsatellite instability (MSI) has been examined in a number of cancers. Squamous cell carcinoma (SCC) and adjacent normal and lichen sclerosis (LS) samples were taken from patients with radical vulvectomies. Vulvar SCC samples were compared with adjacent normal samples using four oligonucleotide markers (BAT-25, BAT-26, D10S208 and D10S587) found to be informative with other carcinomas. Using polymerase chain reaction techniques, 30 vulvar SCC DNA samples were examined for MSI. BAT-26 displayed the highest level of MSI and was considered to be the most sensitive marker in studying vulvar SCC. There …

Quantification Of Marine Sediment Properties From Planar And Volumetric Pore Geometries, Allen Hagerman Reed

LSU Doctoral Dissertations

Pore geometry and topology are important determinants of sediment physical properties, such as porosity and permeability. They also influence processes that occur in the sediment, such as acoustic propagation, attenuation, and dispersion, single- and multi-phase fluid flow, and hydrodynamic dispersion. This study uses images to evaluate pore geometry and topology of ooid (subspherical particles) and siliclastic (angular quartz) sand that was collected from the marine environment south of Bimni Bahamas and Ft. Walton Beach, FL, respectively. Image analysis techniques and predictive tools enable insight into the relationships among sediment pore geometry, topology, and physical properties for these differently shaped sands. …
