Globally, the number of recreational fishers is sizeable and increasing in many countries. Associated with this trend is the potential for negative impacts on fish stocks through exploitation or management measures such as stocking and introduction of non-native fishes. Nevertheless, recreational fishers can be instrumental in successful fisheries conservation through active involvement in, or initiation of, conservation projects to reduce both direct and external stressors contributing to fishery declines. Understanding fishers’ concerns for sustained access to the resource and developing methods for their meaningful participation can have positive impacts on conservation efforts. We examined a suite of case studies that …

Nutrient Uptake By Intact And Disturbed Roots Of Loblolly Pine Seedlings, Melissa S. Lucash, Ruth D. Yanai, J. Devereux Joslin Jan 2008

Nutrient Uptake By Intact And Disturbed Roots Of Loblolly Pine Seedlings, Melissa S. Lucash, Ruth D. Yanai, J. Devereux Joslin

Environmental Science and Management Faculty Publications and Presentations

Most measurements of nutrient uptake use either hydroponic systems or soil-grown roots that have been disturbed by excavation. The first objective of this study was to test how root excavation affects nitrate uptake. Rates of NO3− uptake by mycorrhizal loblolly pine (Pinus taeda L.) seedlings were measured in intact sand-filled columns, hydroponics, and disturbed sand-filled columns. Total nitrate uptake in intact sand-filled columns was higher than in disturbed columns, indicating that disturbance lowers uptake. Transferring plants from the sand-filled columns to hydroponics had little effect on NO3− uptake beyond delaying uptake for an hour. The second objective of this study …

Refactoring Tools: Fitness For Purpose, Emerson Murphy-Hill, Andrew P. Black Jan 2008

Refactoring Tools: Fitness For Purpose, Emerson Murphy-Hill, Andrew P. Black

Computer Science Faculty Publications and Presentations

Refactoring tools can improve the speed and accuracy with which we create and maintain software -- but only if they are used. In practice, tools are not used as much as they could be: this seems to be because sometimes they do not align with the refactoring tactic preferred by the majority of programmers, a tactic we call floss refactoring. We propose five principles that characterize successful floss refactoring tools -- principles that can help programmers to choose the most appropriate refactoring tools and also help toolsmiths to design tools that fit the programmer's purpose.

Warrantless Location Tracking, Ian Samuel Jan 2008

Warrantless Location Tracking, Ian Samuel

Articles by Maurer Faculty

The ubiquity of cell phones has transformed police investigations. Tracking a suspect's movements by following her phone is now a common but largely unnoticed surveillance technique. It is useful, no doubt, precisely because it is so revealing; it also raises significant privacy concerns. In this Note, I consider what the procedural requirements for cell phone tracking should be by examining the relevant statutory and constitutional law. Ultimately, the best standard is probable cause; only an ordinary warrant can satisfy the text of the statutes and the mandates of the Constitution.

The Copula: A Tool For Simulating Speckle Dynamics, Donald D. Duncan, Sean J. Kirkpatrick Jan 2008

The Copula: A Tool For Simulating Speckle Dynamics, Donald D. Duncan, Sean J. Kirkpatrick

Electrical and Computer Engineering Faculty Publications and Presentations

Use of a copula for generating a sequence of correlated speckle patterns is introduced. The chief characteristic of this algorithm is that it generates a continuous speckle sequence with a specified evolution of the correlation and does so with just two arrays of random numbers. Thus, physically realistic temporally varying speckle patterns with proper first- and second-order statistics are easily realized. We illustrate use of the algorithm for generating sequences with prescribed Gaussian, exponential, and equal-interval correlations and demonstrate how correlation times can be specified independently. This approach to generating sequences of random realizations with prescribed correlations should prove useful …

Statistics Of Local Speckle Contrast, Donald D. Duncan, Sean J. Kirkpatrick, Ruikang K. Wang Jan 2008

Statistics Of Local Speckle Contrast, Donald D. Duncan, Sean J. Kirkpatrick, Ruikang K. Wang

Electrical and Computer Engineering Faculty Publications and Presentations

In describing the first-order properties of laser speckle under polarized illumination conditions, it is almost an article of faith that the contrast is unity. In many processing schemes, however, the contrast defined as the quotient of the standard deviation and the mean is calculated over a localized spatial region. In such cases, this local contrast displays a distribution of values that can depart substantially from unity. Properties of this distribution depend on details of the data acquisition and on the size of the local neighborhood over which the contrast is calculated. We demonstrate that this local contrast can be characterized …

Flexibility Of Knowledge As A Function Of Practice And Explicit Instruction, Bill Sallas Jan 2008

Flexibility Of Knowledge As A Function Of Practice And Explicit Instruction, Bill Sallas

LSU Doctoral Dissertations

Two experiments used a dynamic control task (Berry & Broadbent, 1984) to examine the flexibility of experientially acquired knowledge. The results suggest that experientially acquired knowledge of this task is represented by a lookup table, not a set of tuned strategies. With practice, transfer to a new task was achieved through an extrapolation procedure. Experiment 2 demonstrated far superior task and transfer performance in participants trained with a combination of experiential practice and model-based knowledge. Transfer to new states was only possible when participants were provided with model-based knowledge through direct instruction. Also, providing model-based knowledge during practice resulted in …

Evolutionary History And Hybridization In Passerina Buntings, Matthew D. Carling Jan 2008

Evolutionary History And Hybridization In Passerina Buntings, Matthew D. Carling

LSU Doctoral Dissertations

Understanding the genetic basis of speciation is of fundamental importance to evolutionary biology and hybrid zones offer unique natural laboratories in which to investigate the ecological and evolutionary processes important in creating and maintaining biological diversity. By comparing introgression patterns of different loci, researchers can begin to identify genetic regions that contribute to reproductive isolation between hybridizing taxa. In taxa, like birds, with heterogametic females, Haldane’s rule predicts that mtDNA and z-linked loci will introgress less than autosomal loci. I tested this prediction using the hybrid zone between Passerina cyanea (Indigo Bunting) and Passerina amoena (Lazuli Bunting), two species that …

Research Summary: Courageous, Collaborative Leadership, Vincent A. Anfara Jr., P. Elizabeth Pate, Micki M. Caskey, P. Gayle Andrews, Larry G. Daniel, Steven B. Mertens, Mike Muir

Curriculum and Instruction Faculty Publications and Presentations

While courageous, collaborative leadership has not been formally recognized as a “model” by those who study educational leadership, there is a wealth of information about collaborative (i.e., participatory) leadership and a growing corpus of literature focused on courageous leadership. As in the development of the ideas connected to collaborative leadership, the world of business is taking the lead in delineating what courageous leadership means. Some of this literature has even surfaced in the realm of religious studies (Hybels, 2002). Simply defined, courageousness in leadership addresses the necessity to step outside the box and take chances to help the organization establish …

Influences Of Maternal Corticosterone On Incubation Length And Hatchability Of Eggs Laid By Quail Hens Selected For Divergent Adrenocortical Stress Responsiveness, Jason Berante' Schmidt Jan 2008

Influences Of Maternal Corticosterone On Incubation Length And Hatchability Of Eggs Laid By Quail Hens Selected For Divergent Adrenocortical Stress Responsiveness, Jason Berante' Schmidt

LSU Master's Theses

Unstressed and stressed quail hens selected for exaggerated (HS, high stress) rather than reduced (LS, low stress) plasma corticosterone (B) response to brief restraint deposit more B into their eggs than do their LS hen counterparts. HS hens implanted with B also show reduced egg lay when compared to LS- and HS-control and LS-B-implanted hens. Herein, the effects of stress line on length of egg incubation (LEI) and chick body weight at emergence (BWTE) (Exp. 1) and the interactive influences of line with maternal B-treatment (sub-Q control, CON-, or B-implants) on LEI (Exp. 2) and on egg fertility (FERT), total …

"I Will Learn You Something If You Listen To This Song": Southern Women Writers' Representations Of Music In Fiction, Courtney George Jan 2008

"I Will Learn You Something If You Listen To This Song": Southern Women Writers' Representations Of Music In Fiction, Courtney George

LSU Doctoral Dissertations

This dissertation offers a rhetorical analysis of the formation of women’s memory, history, and communities in intersections of musical and literary expression in the American South, a region graced with a vital but underexamined tradition of female musicianship. Recent scholars have deconstructed the imagined narrative of southern culture as static, patriarchal, and white to uncover alternative stories and cultures that exist outside of canonical literature. This project significantly expands current understandings of these conflicting narratives by investigating how women writers recall, reclaim, and re-envision women’s roles in southern music to challenge, comply, and/or identify with women’s prescribed place in the …

A 5000-Year History Of Caribbean Environmental Change And Hurricane Activity Reconstructed From Coastal Lake Sediments Of The West Indies, Jason Thomas Knowles Jan 2008

A 5000-Year History Of Caribbean Environmental Change And Hurricane Activity Reconstructed From Coastal Lake Sediments Of The West Indies, Jason Thomas Knowles

LSU Doctoral Dissertations

A ~5000 yr history of modern and prehistoric hurricane landfall and environmental change has been reconstructed from coastal lake sediments of the northern West Indies. Hurricane overwash layers and environmental shifts were identified by changes in biological and sedimentary stratigraphies, core lithology, and loss-on-ignition techniques. 14C and 137Cs were used to establish a chronology of events. Many hurricane-induced overwash layers were identified within the lake sediments. Evidence indicates distinct periods of temporal shifts in hurricane activity for the Northern Caribbean islands of Anguilla, Barbuda, and Acklins Island, Bahamas, providing the first paleotempestological records for the region. The northern Caribbean record …

Magnetic Field Effects On Diffusion Flames, Diego F. Gonzalez Jan 2008

Magnetic Field Effects On Diffusion Flames, Diego F. Gonzalez

LSU Master's Theses

Magnetic field effects in combustion is an area of study that has previously been overlooked. The influence of magnetic fields on flames has only recently been explored and is of interest both from a scientific and a practical standpoint. This study provides theoretical, numerical and experimental evidence that combustion can be affected with the use of suitable magnetic fields. This thesis focuses on four different types of magnetic field: homogeneous, gradient, oscillating and pre-combustion. For the homogeneous field case, the Gibbs Free Energy method was used to determine the mole fraction of product species. It was found that homogeneous fields …

Examining The Effects Of Non-Intensive Therapy On Word Retrieval, Apraxic Errors And Quality Of Life Following Intensive Therapy, Erin Lofton Cain Jan 2008

Examining The Effects Of Non-Intensive Therapy On Word Retrieval, Apraxic Errors And Quality Of Life Following Intensive Therapy, Erin Lofton Cain

LSU Master's Theses

The purpose of this study was to determine if given a period of intensive aphasia therapy a patient diagnosed with aphasia and an accompanying apraxia would maintain, gain, or lose skills during non-intensive therapy. A literature review revealed that intensive therapy has been shown to increase a patient's skill level in various areas. However, very little research was found that focused on how these patients' perform when reintroduced to typical aphasia therapy. This study proposed three specific questions: if the participant would retain her current level of word retrieval functioning evident after intensive therapy, if the participant would retain her …

Racial Disparities In The Us Healthcare System, J. Paul Nielsen Jan 2008

Racial Disparities In The Us Healthcare System, J. Paul Nielsen

Quill & Scope

Provider mentality regarding minorities, both overt and subconscious, likely affects the quality of healthcare delivered. Survey research suggests that most (between 50-75%) Caucasian people believe minorities are less intelligent, more prone to violence, and less likely to be employed. More physicians identify themselves as Caucasian than all other races combined. One in five Spanish-speaking Latinos reports not seeking healthcare due to language barriers. Even when they have overcome barriers to getting healthcare, minority populations are still less likely than Caucasians to receive certain common medical procedures.

Africanisms And Cultural Modifications: A Study At Southall Quarter, Williamsburg, Virginia, Jessie Chaiya Cohen Jan 2008

Africanisms And Cultural Modifications: A Study At Southall Quarter, Williamsburg, Virginia, Jessie Chaiya Cohen

LSU Master's Theses

Archaeological studies at sites of enslaved Africans and African-Americans have been intensely undertaken in recent years. In particular, the search for Africanisms and cultural processes has become a common trend within these studies. I analyzed previously recorded investigations of Southall Quarter (44JC969), an eighteenth-century enslaved African and African-American site in James City County, Virginia. Dominating anthropological themes of slave resistance, owner-imposed hegemony, and agentic actions guided my search for Africanisms at Southall Quarter. I hoped to prove that the distance of the quarters from Southall’s residence and therefore the lax owner supervision provided the enslaved inhabitants with opportunities to express …

Titian, The Pesaro, And The Frari: Different Strokes For Different Folks, Carl Edward Blyskal Jan 2008

Titian, The Pesaro, And The Frari: Different Strokes For Different Folks, Carl Edward Blyskal

LSU Master's Theses

This thesis parses two early paintings by the Venetian High Renaissance artist Titian. The discussions analyze the circumstances and patronage, compositional elements, iconography, and meanings of each work that lead through a maze of often contradictory art historical scholarship. This journey concludes by my proffering greater insights for each extraordinary painting by this internationally renowned artist. The earliest extant work by Titian--St. Peter Enthroned, with Donor and Pop--is a wonderful, if somewhat awkward, completion of a commission begun by Giovanni Bellini. Dating controversies over the centuries are examined, and a secure time-frame of 1506 to the first half of 1507 …

Transition Experiences Of Selected Emerging Adults With Emotional And Behavioral Difficulties In Higher Education, Kathleen M. Fowler Jan 2008

Transition Experiences Of Selected Emerging Adults With Emotional And Behavioral Difficulties In Higher Education, Kathleen M. Fowler

USF Tampa Graduate Theses and Dissertations

Transitioning into adulthood is an exciting and challenging time for emerging adults, and is even more difficult for young adults with emotional and behavioral difficulties (EBD). Even though the number of transition-aged individuals with EBD is significant, few studies have explored the experiences of this population engaged in educational activities, and there is limited information regarding the personal experiences of emerging adults with EBD. The purpose of the study is to acquire a better understanding of the experiences of young adults diagnosed with an EBD who are working toward their academic goals. Further, this study may give voice to individuals …

A Study Of Compliance In Aged Care Facilities With Regards To Australian Standards 1851:2006 Maintenance Of Fire Protection Systems And Equipment Section 17, Robert Doleman Jan 2008

A Study Of Compliance In Aged Care Facilities With Regards To Australian Standards 1851:2006 Maintenance Of Fire Protection Systems And Equipment Section 17, Robert Doleman

Theses : Honours

The management of risk within a nursing home environment is widely viewed as an undertaking perfom1ed by the owners or managers of nursing homes. The residents of these homes are reliant upon the owners and managers to keep them safe, due in part to a traditional belief that they are the experts and have a greater understanding of risk. To establish risk it is first a requirement to have an understanding of levels of risk and risk management techniques. Risk appreciation is often influenced by heuristic representativeness, as well as social and cultural influences. The higher level of risk within …

Exploration Of The Authentic Apology Theory: An Examination Of The Reasons Why People Reject An Apology, Stephenie Bruce Jan 2008

Exploration Of The Authentic Apology Theory: An Examination Of The Reasons Why People Reject An Apology, Stephenie Bruce

Theses : Honours

The aim of the present literature review was to explore the reasons why people reject an apology. A search of the literature revealed virtually no research focusing specifically on apology rejection, therefore, it was proposed that this lack of research may be due to the general reluctance of apology recipients to respond with rejection (Bennett & Dewberry, 1994; Bennett & Earwaker, 1994; Risen & Gilovich, 2007). Given the dearth of literature on apology rejection, it was imperative that the review also examined the literature on apology in general, in addition to literature on apology and forgiveness, in order to discover …
