Monitoring In Event-Based Prospective Memory Tasks, Dale Watkins Cockman Jan 2003

Monitoring In Event-Based Prospective Memory Tasks, Dale Watkins Cockman

LSU Master's Theses

Event based prospective memory (PM) refers to remembering to perform a particular action upon the presentation of a particular cue in the environment. Until recently, most models of event-based PM performance have suggested that the realization of the target event occurs automatically. The DARC model (Smith, 2000) is among the first to suggest that monitoring is required to notice the target event, in the form of a consistent, non-strategic dedication of resources. The predictions of the DARC model are contrasted with those of Einstein & McDaniel (Noticing + Search, 1996), Goschke & Kuhl (1996), Ellis (1996). The pilot study and …

Efficient Embedding Of Virtual Hypercubes In Irregular Wdm Optical Networks, Guru Prasad P. Kithlanagamangala Jan 2003

Efficient Embedding Of Virtual Hypercubes In Irregular Wdm Optical Networks, Guru Prasad P. Kithlanagamangala

LSU Master's Theses

This thesis addresses one of the important issues in designing future WDM optical networks. Such networks are expected to employ an all-optical control plane for dissemination of network state information. It has recently been suggested that an efficient control plane will require non-blocking communication infrastructure and routing techniques. However, the irregular nature of most WDM networks does not lend itself to efficient non-blocking communications. It has been recently shown that hypercubes offer some very efficient non-blocking solutions for, all-to-all broadcast operations, which would be very attractive for control plane implementation. Such results can be utilized by embedding virtual structures in …

Ethics In Public Relations: Gauging Ethical Decision-Making Patterns Of Public Relations Practitioners, Paul Stuart Lieber Jan 2003

Ethics In Public Relations: Gauging Ethical Decision-Making Patterns Of Public Relations Practitioners, Paul Stuart Lieber

LSU Master's Theses

This study employed the Defining Issues Test (DIT) and a quantitative version of the five-factor TARES Test to gather data on the ethical decision-making patterns of public relations practitioners. The former is an instrument based on Kohlberg’s (1969) moral development theory, the latter self-enforced, ethical consideration statements derived from the research of Baker and Martinson (2001). Results show that levels of moral development in public relations differ based on job segment, and that age, education, gender and rank significantly affect levels of ethical consideration. The TARES test, it was discovered, is better suited for a three-factor configuration based on Day’s …

Experimental Predator Removal: A Response In Small Mammal Communities And Relations To Duck Nest Success, Jeremy Paul Adkins Jan 2003

Experimental Predator Removal: A Response In Small Mammal Communities And Relations To Duck Nest Success, Jeremy Paul Adkins

LSU Master's Theses

Reducing predator populations in the prairie pothole region can greatly increase nest success of both over water and upland nesting ducks. However, little is understood about impacts of predator removal on other wildlife within the same area. I conducted a field experiment to test whether small mammals, primarily mice (Peromyscus sp.) and voles (Microtus sp.), responded to seasonally reduced predator abundance. I compared small mammal abundance on 10 experimental (259 ha) sites in North Dakota during 2001 and 2002 with intensive, seasonal predator trapping with 10 control sites (259 ha) also monitored in both years. Small mammals were more abundant …

Arithmetic Logic Unit (Alu) Design Using Reconfigurable Cmos Logic, Chandra Srinivasan Jan 2003

Arithmetic Logic Unit (Alu) Design Using Reconfigurable Cmos Logic, Chandra Srinivasan

LSU Master's Theses

Using the reconfigurable logic of multi-input floating gate MOSFETs, a 4-bit ALU has been designed for 3V operation. The ALU can perform four arithmetic and four logical operations. Multi- input floating gate (MIFG) transistors have been promising in realizing increased functionality on a chip. A multi- input floating gate MOS transistor accepts multiple inputs signals, calculates the weighted sum of all input signals and then controls the ON and OFF states of the transistor. This enhances the transistor function to more than just switching. This changes the way a logic function can be realized. Implementing a design using multi-input floating …

Correlation Of Core Characteristics To Outcrop Upper Jackfork Group Turbidites, Degray Lake, Arkansas, Daniel James Golob

LSU Master's Theses

Pennsylvanian age Jackfork Group cores from the DeGray Lake Dam and outcrop from the east wall of the DeGray Lake Spillway, Arkansas, provide an opportunity for a detailed study on the transport and depositional characteristics of a fine-grained, deep-water depositional system. Two phases of resedimentation processes are responsible for deposition of the sediments in the cores and the outcrop. Primary resedimentation processes transport terrigenous sediments from the shelf or basin edge into the middle fan environment, while secondary resedimentation alter the sediments after they are initially deposited in the environment. Debris flows, slurry flows, and high and low density turbidity …

Media Ownership And Objectivity, Xinkun Wang Jan 2003

Media Ownership And Objectivity, Xinkun Wang

LSU Master's Theses

The purpose of this study is to examine whether the different type of ownership will affect the degree of objectivity of newspaper coverage of 2000 presidential election. It is predicted by Shoemaker’s news content theory that publicly-owned newspaper is more objective than privately-owned newspaper. The findings of this study support this theory. A content analysis of 238 news stories and eight editorials from publicly-owned the Boston Globe and privately-owned the Boston Herald showed that not only does the ownership affect the objectivity of the coverage of these two newspapers on 2000 presidential election, the endorsements also affect the degree of …

Revisiting A "Lost Victory" At Kursk, Jonathan Page Klug Jan 2003

Revisiting A "Lost Victory" At Kursk, Jonathan Page Klug

LSU Master's Theses

The battle of Kursk in the summer of 1943 was a pivotal battle of World War II. The defeat at Kursk placed the Wehrmacht on the permanent strategic defensive on the Eastern Front. The opening of the Soviet archives after 1989 has permitted more thorough analysis of that battle and produced greater appreciation of the Red Army’s performance, while casting doubt on the notion that the Germans were close to an operational victory. Preceding the clash, both sides prepared feverishly, attempting to bring the units involved to their maximum capability by replacing personnel, upgrading equipment, and conducting training. The Germans …

Numerical Solution Of Ocular Fluid Dynamics, Satish Kumar Jan 2003

Numerical Solution Of Ocular Fluid Dynamics, Satish Kumar

LSU Master's Theses

Numerical calculations of the aqueous humor dynamics in the anterior chamber of both the rabbit and the human eye are presented to delineate the basic flow and transport mechanisms. The calculations are based on a geometrical model of the eye, which represents the Trabecular mesh (TM) as a multi-layered porous zone of specified pore sizes and void fraction. Buoyancy is observed to be the dominant driving mechanism for the convective motion in both orientations (horizontal and vertical) of the eye. Reducing the TM pore size does not appear to have a significant influence on the intra-ocular pressure (IOP) until the …

Heavy Smokers Choose Large, Immediate Rewards With Large Penalties On A Simulated Task Of Gambling, Michael Shawn Businelle Jan 2003

Heavy Smokers Choose Large, Immediate Rewards With Large Penalties On A Simulated Task Of Gambling, Michael Shawn Businelle

LSU Master's Theses

The Gambling Task is a complex neuropsychological test (in the form of a card game) that examines the ability of individuals to assess potential immediate gains over long-term losses. Gambling Task performance has been examined in previous studies with individuals who are dependent on alcohol, cocaine, heroin, and amphetamine. These studies have shown that those who are dependent on the aforementioned substances perform more poorly on the Gambling Task than controls. Specifically, in relation to controls, drug/alcohol dependent individuals show impairment by tending to pick more cards that have large immediate gains and very large delayed punishers. The delayed punisher …

Development Of A Performance-Based Design Approach And Related Loads For Facilities Designated As Essential During A Hurricane Event, Joffrey Elliott Easley Jan 2003

Development Of A Performance-Based Design Approach And Related Loads For Facilities Designated As Essential During A Hurricane Event, Joffrey Elliott Easley

LSU Master's Theses

Historically, shelters and other facilities designated as "essential" during hurricanes have experienced unacceptable damage during recent hurricanes, exposing the occupants to uncomfortable and dangerous conditions. One of the reasons for this is the lack of standards or design guidelines addressing the special considerations required for such facilities. A new approach to the design of essential facilities in hurricane regions is proposed. The goal of this work is to create a tool for improving the safety and serviceability of evacuation shelters and other critical facilities utilized during hurricane events. This is achieved by developing a new philosophy based on selection of …

Middle Miocene Grounding Events On The Ross Sea Outer Continental Shelf, Antarctica, Juan Manuel Chow Jan 2003

Middle Miocene Grounding Events On The Ross Sea Outer Continental Shelf, Antarctica, Juan Manuel Chow

LSU Master's Theses

The middle Miocene δ18O enrichments from deep-sea data and eustatic sea level falls are traditionally attributed to expansion of the East Antarctic Ice Sheet. Interpretations of such data have led many to conclude that the West Antarctic Ice Sheet (WAIS) was not well-developed until the late Miocene. In such a scenario, middle Miocene glaciation on the Ross Sea shelf would have had to be minimal, perhaps in the form of ice caps, to be consistent with proxy data. New seismic-stratigraphic analysis of the Ross Sea outer continental shelf suggests that at least five grounding events (ice sheet advances …

A Parametrization Approach For Solving The Hamilton-Jacobi-Equation And Application To The A2 Toda Lattice, Mohammad Dikko Aliyu Jan 2003

A Parametrization Approach For Solving The Hamilton-Jacobi-Equation And Application To The A2 Toda Lattice, Mohammad Dikko Aliyu

LSU Master's Theses

Hamilton-Jacobi (HJ)-theory is an extension of Lagrangian mechanics and concerns itself with a directed search for a coordinate transformation in which the equations of motion can be easily integrated. The equations of motion of a given mechanical system can often be simplified considerably by a suitable transformation of variables such that all the new position and momemtum coordinates are constants. A particular type of transformation is chosen in such a way that the new equations of motion retain the same form as in the former coordinates; such a transformation is called canonical or contact and can greatly simplify the solution …

Computer Assisted Eye Fungal Infection Diagnosis, Madhusudhanan Balasubramanian Jan 2003

Computer Assisted Eye Fungal Infection Diagnosis, Madhusudhanan Balasubramanian

LSU Master's Theses

In this thesis, an attempt has been made to assist the diagnosis of Fungal Keratitis, a fungal infection that occurs in the corneal layers of the eye, by identifying the region of infection in the corneal images using fractal-based features. Three features related to the fractal dimension of the surface of the image, when represented in a 3D using the pixel intensity measure, are used to identify these regions in the image. To reduce the computation complexity, Fisher linear discriminant (FLD) is used to reduce the 3D raw feature to 1D feature, while preserving feature values. Using the adaptive mixtures …
