Movements And Habitat Use Of Southeastern Blue Sucker Cycleptus Merdionalis In The Lower Pearl River, Devon Charles Oliver Jan 2012

Movements And Habitat Use Of Southeastern Blue Sucker Cycleptus Merdionalis In The Lower Pearl River, Devon Charles Oliver

LSU Master's Theses

Riverine fisheries management programs often do not focus on non-sport and non-commercial fishes, such as catostomids, yet many suckers have become threatened or endangered throughout river systems in the United States because of habitat alterations. In the Pearl River, sedimentation, dam construction, and other hydrologic modifications have negatively impacted habitats used by southeastern blue suckers Cycleptus meridionalis, a species of concern in both Louisiana and Mississippi. The principal objective of this project was to investigate habitat use of likely historically abundant southeastern blue suckers in the lower Pearl River. During electrofishing surveys in 2010 and 2011, we observed no southeastern …

Experimental Study Of Lean Blowout With Hydrogen Addition In A Swirl-Stabilized Premixed Combustor, Shengrong Zhu Jan 2012

Experimental Study Of Lean Blowout With Hydrogen Addition In A Swirl-Stabilized Premixed Combustor, Shengrong Zhu

LSU Doctoral Dissertations

Lean premixed combustion is widely used to achieve a better compromise between nitric oxides emissions and combustion efficiency. However, combustor operation near the lean blowout limit can render the flame unstable and lead to oscillations, flashback, or extinction, thereby limiting the potential range of lean combustion. Recent interest in integrated gasification combined cycle plants and syngas combustion requires an improved understanding of the role of hydrogen on the combustion process. Therefore, in present study, combustion of pure methane and blended methane-hydrogen has been conducted in a swirl stabilized premixed combustor. The measurement techniques implemented mainly include particle image velocimetry, CH*/OH* …

Impact Of Plug-In Electrical Cars On Energy Demand, On Power System And On Environment, Sital Tiwari Jan 2012

Impact Of Plug-In Electrical Cars On Energy Demand, On Power System And On Environment, Sital Tiwari

LSU Master's Theses

The use of an electric vehicle (EV) over a gasoline vehicle (GV) is often portrayed as environment friendly or green movement ignoring how the electricity is produced. EVs get credit for preserving green environment and preventing global warming by minimizing the dependency on oil. Most of the time, these assumptions that favor EV are not well justified. Therefore, proper studies on the impact of electric vehicles on energy demand, on environment and on power system are necessary before reaching to any conclusion. This thesis explores the possibility of energy consumption pattern shift within the different sectors of energy use due …

On Tax Increase Limitations: Part Ii -- Evasion And Transcendence, David Gamage, Darien Shanske Jan 2012

On Tax Increase Limitations: Part Ii -- Evasion And Transcendence, David Gamage, Darien Shanske

Articles by Maurer Faculty

In this essay, the second of a series, we continue our evaluation of state Tax Increase Limitations (TILs) – special rules that limit state legislatures’ ability to raise taxes, such as by requiring supermajority votes. We analyze two strategies whereby majority parties can evade TILs to the extent they so desire. We further argue that these strategies have some positive normative features. The strategies designed to evade TILs may ultimately lead toward a more effective means for controlling the size of state government than TILs themselves are able to provide.

Vendor Compensation As An Approach For State "Amazon" Laws: Part 2, David Gamage, Devin J. Heckman

Articles by Maurer Faculty

In this essay, the second of a two-part series, we propose an approach for the U.S. states to tax interstate e-commerce. If the states adequately compensate remote e-commerce vendors for all tax compliance costs, we argue that the states can constitutionally impose use tax collection obligations on the remote vendors in a manner compatible with the Quill framework.

The Saga Of State "Amazon" Laws: Reflections On The Colorado Decision, David Gamage, Darien Shanske Jan 2012

The Saga Of State "Amazon" Laws: Reflections On The Colorado Decision, David Gamage, Darien Shanske

Articles by Maurer Faculty

We analyze the Colorado district court’s decision in Direct Marketing Association v. Huber – a decision that permanently enjoined Colorado’s "Amazon" law. Had it not been enjoined, the Colorado law would have mandated information reporting by remote e-commerce vendors so that Colorado could levy its sales and use tax on the e-commerce purchases made by Colorado residents. We evaluate the applicability of the Tax (Anti-)Injunction Act and whether the Colorado statute and regulations should be reviewed as a tax or as a regulation. We also suggest alternative approaches that state legislatures might use in order to levy taxes on remote …

Vendor Compensation As An Approach For State "Amazon" Laws: Part 1, David Gamage, Devin J. Heckman

Articles by Maurer Faculty

In this Essay, the first of a two-part series, we analyze the approaches U.S. states have been using in their attempts to tax interstate e-commerce. We argue that these existing approaches are unlikely to be effective. In our companion Essay, the second in the series, we outline a novel approach that states might employ in order to more effectively tax interstate e-commerce – based on adequately compensating remote vendors for all tax compliance costs. But before we can argue for our new approach, we must first survey the current constitutional and statutory landscape.

The Effect Of Extrinsic Rewards In The High School Classroom, Amanda Vargo Jan 2012

The Effect Of Extrinsic Rewards In The High School Classroom, Amanda Vargo

LSU Master's Theses

One of the biggest obstacles that a high school teacher faces in the classroom is motivating students to complete work. Traditional ideology focuses on intrinsic rewards as way to encourage students to participate and try in the classroom. Things like valuing education, planning for college, and taking pride in a good report card are used in attempts to motivate. Yet, in the adult world, people expect a concrete extrinsic reward (i.e. a paycheck) for the work that they do. This study takes the idea of extrinsic rewards and brings them into the classroom. This study was conducted over two academic …

Fixing Mechanics: A Study In Cross-Curricular Use Of Rubrics To Grade Writing, Jeanette Martin Miller Jan 2012

Fixing Mechanics: A Study In Cross-Curricular Use Of Rubrics To Grade Writing, Jeanette Martin Miller

LSU Master's Theses

Teachers who assign and grade writing sometimes use rubrics to assist in this process. A rubric usually consists of a set of rules, guidelines, or criteria that must be met for students to obtain a passing grade. Rubrics are intended to take the subjectivity out of grading writing and to give feedback to the student for further improvement. Because even English teachers disagree about the use of rubrics to grade writing, and the criteria that is most important within the rubrics, hearing from teachers in other subject areas could help all teachers better understand how to grade writing assignments. This …

Ensemble Methods For Malware Diagnosis Based On One-Class Svms, Xing An Jan 2012

Ensemble Methods For Malware Diagnosis Based On One-Class Svms, Xing An

LSU Master's Theses

Malware diagnosis is one of today’s most popular topics of machine learning. Instead of simply applying all the classical classification algorithms to the problem and claim the highest accuracy as the result of prediction, which is the typical approach adopted by studies of this kind, we stick to the Support Vector Machine (SVM) classifier and based on our observation of some principles of learning, characteristics of statistics and the behavior of SVM, we employed a number of the potential preprocessing or ensemble methods including rescaling, bagging and clustering that may enhance the performance to the classical algorithm. We implemented the …

Pressures, Centralization, Economics, Technology, And Ethics: Factors That Impact Public Information Officer - Journalist Relationships, Christopher Jon Mccollough Jan 2012

Pressures, Centralization, Economics, Technology, And Ethics: Factors That Impact Public Information Officer - Journalist Relationships, Christopher Jon Mccollough

LSU Doctoral Dissertations

A study of public information officers (PIOs) in three states and the journalists that cover state government finds five primary factors that shape the working relationships between both groups. Institutional pressures on both PIOs and journalists impact the ability of both parties to meet the needs of the other party on a daily basis. High levels of centralization in state government communication limit the ability of PIOs to meet the needs of journalists, fostering journalists’ antagonism and a more combative working relationship. The economic decline of journalism is creating a dichotomous situation where PIOs can help journalists manage increasing demands …

Imperial Consensus: The English Press And India, 1919-1935, David Lilly Jan 2012

Imperial Consensus: The English Press And India, 1919-1935, David Lilly

LSU Doctoral Dissertations

Between 1919 and 1935, the lion’s share of the interwar era, the British government’s most important overriding task was constitutional reform of India. The subcontinent’s importance to Britain was undoubted: economically as an important trading partner and militarily a source of fighting men and material, as demonstrated in the Great War. However, scholars have relegated India to a relatively minor topic and instead have portrayed Britain’s interwar period as the era of appeasement. Appeasement only became an issue in 1935 and a major topic with the Munich crisis of September 1938. Voluminous press coverage of the India issue throughout the …
