Getting Plant Conservation Right (Or Not): The Case Of The United States, Kayri Havens, Andrea T. Kramer, Edward O. Guerrant Jr. Jan 2014

Getting Plant Conservation Right (Or Not): The Case Of The United States, Kayri Havens, Andrea T. Kramer, Edward O. Guerrant Jr.

Environmental Science and Management Faculty Publications and Presentations

Effective plant conservation includes addressing basic needs such as information about species distribution and rarity; research, management, education, and training capacity to mitigate threats facing threatened species; policy and funding to support continued capacity and conservation; and, ultimately, a public that understands and supports the importance of plants and the need for their conservation. Coordination of plant conservation efforts is also needed to ensure that resources and expertise are used in a strategic, efficient, and effective manner.We argue that no country is currently getting plant conservation right; plants are becoming increasingly rare around the world. Plants are often not fully …

Improving The Representation Of Roots In Terrestrial Models, Erica A.H. Smithwick, Melissa S. Lucash, M. Luke Mccormack, Gajan Sivandran Jan 2014

Improving The Representation Of Roots In Terrestrial Models, Erica A.H. Smithwick, Melissa S. Lucash, M. Luke Mccormack, Gajan Sivandran

Environmental Science and Management Faculty Publications and Presentations

Root biomass, root production and lifespan, and root-mycorrhizal interactions govern soil carbon fluxes and resource uptake and are critical components of terrestrial models. However, limitations in data and confusions over terminology, together with a strong dependence on a small set of conceptual frameworks, have limited the exploration of root function in terrestrial models. We review the key root processes of interest to both field ecologists and modelers including root classification, production, turnover, biomass, resource uptake, and depth distribution to ask (1) what are contemporary approaches for modeling roots in terrestrial models? and (2) can these approaches be improved via recent …

Access To Counsel: Psychological Science Can Improve The Promise Of Civil Rights Enforcement, Victor D. Quintanilla, Cheryl R. Kaiser Jan 2014

Access To Counsel: Psychological Science Can Improve The Promise Of Civil Rights Enforcement, Victor D. Quintanilla, Cheryl R. Kaiser

Articles by Maurer Faculty

Employment discrimination claimants in general, and racial minority claimants in particular, disproportionately lack access to legal counsel. When employment discrimination claimants lack counsel, they typically abandon their claims, or if they pursue their claims, they do so pro se (without counsel), a strategy that is seldom successful in court. Access to counsel is, hence, a decisive component in whether employment discrimination victims realize the potential of civil rights enforcement. Psychological science analyzes access to counsel by identifying psychological barriers—such as threatened social identity, mistrust in legal authorities, and fear of repercussions—that prevent employment discrimination victims from pursuing counsel. The analysis …

Moral Vulnerability And The Task Of Reparations, Margaret Urban Walker Jan 2014

Moral Vulnerability And The Task Of Reparations, Margaret Urban Walker

Philosophy Faculty Research and Publications

This essay seeks to understand the domain and demands of reparative justice in terms of moral vulnerability. Significant harms raise the question of whether victims stand in truly reciprocal practices of accountability; if they do, they enjoy the power of calling others to account as well as bearing the liability of being accountable to others. In the aftermath of harms, victims’ moral vulnerability is tested: they may be exposed to the insult and injury of discovering that they do not enjoy the moral standing of holding others accountable. While the occasion of reparative justice is significant wrongs and wrongful harms …

Design, Synthesis, And Exploration Of A Chimeric Antioxidant And New Crosslinkers For Molecular Imprinting, Danielle Songe Meador Jan 2014

Design, Synthesis, And Exploration Of A Chimeric Antioxidant And New Crosslinkers For Molecular Imprinting, Danielle Songe Meador

LSU Doctoral Dissertations

The improvement and utility of crosslinkers are important topics of molecular imprinting. Crosslinker significance is evident when molecularly imprinted polymer (MIP) composition related to performance as separation media is examined. Crosslinkers account for the bulk of MIP formulations made through traditional imprinting (80-90%) and is even greater when the One Monomer Molecularly Imprinted Polymer (OMNiMIP) approach is utilized (100%.) It is not surprising that alteration of the bulk component will result in different separation performances. Crosslinkers studied in this work were designed, synthesized, and evaluated toward improvement in OMNiMIP selectivity. In particular, functionality and number of polymerizable groups, addition of …

Reductive Alkylation Of Proteins Towards Structural And Biological Applications, Kevin Jerome Roberson Jan 2014

Reductive Alkylation Of Proteins Towards Structural And Biological Applications, Kevin Jerome Roberson

LSU Doctoral Dissertations

Nuclear magnetic resonance (NMR) spectroscopy is a proven technique for protein structure and dynamic studies, typically requiring the incorporation of stable magnetic isotopes to improve sensitivity and assign resonances. Degenerate levels of 13C-incorporation have been the biggest obstacle for mass spectrometry-assisted assignment of 13C-dimethylamine resonances in nuclear magnetic resonance spectroscopy (NMR). Reductive 13C-methylation is an alternative labeling method for proteins not amenable to bacterial host overexpression. Because reductive 13C-methylation adds sparse, isotopic labels, traditional methods of assigning the NMR signals are not applicable. The research presented in the first part of this dissertation explores several methods used to break the …

Many Internet users have encountered geoblocking tools – tools that prevent users from accessing certain content on the Internet based on the location from which the users are connecting to the Internet. Because at least some users want to access such content, they turn to tools that enable them to evade geoblocking, to appear on the Internet as if they were located in another location, and to access the content that is available in this other location. So far these activities appear to be under the radar of intellectual property (“IP”) owners, perhaps because geoblocking evasion by users for the …

How Masculinities Distribute Power: The Influence Of Ann Scales, Ann C. Mcginley, Frank Rudy Cooper Jan 2014

How Masculinities Distribute Power: The Influence Of Ann Scales, Ann C. Mcginley, Frank Rudy Cooper

Scholarly Works

Ann Scales's scholarship on masculinities in relation to sexual assault and militarism prompted us to consider exactly how power is distributed by assumptions about what is masculine. For instance, men privileged by association with hegemonic masculinities — those most dominant and preferred — are sometimes excused for acts of violence against people who are denigrated as unmasculine or excessively masculine. In one set of examples, communities excuse football players for sexual assaults on grounds that "boys will be boys." The implication is that boys should be allowed to act out before taking on adult responsibilities, and that they need to …

Assimilation, A Biological Nitrogen Removal Strategy For Freshwater Ornamental Fish Hatcheries, Fatemehsadat Fahandezhsadi Jan 2014

Assimilation, A Biological Nitrogen Removal Strategy For Freshwater Ornamental Fish Hatcheries, Fatemehsadat Fahandezhsadi

LSU Master's Theses

Freshwater ornamental fish production is a major component of aquaculture in the southeastern United States. Closed recirculating aquaculture systems (RASs) allow freshwater ornamental fish hatcheries to mimic native water quality conditions for sensitive species. Total ammonia-N (TAN) removal is the major concern for closed RASs. Biological nitrification is the common method to control TAN. However, the nitrification process might be impaired in acidic water condition with pH<7. Another issue of using the nitrification process for TAN removal is that the nitrification is not sufficient to compensate for the amount of ammonia released in larval production systems because of slow growth rate of nitrifying bacteria. To address these issues, this study suggests an aerobic assimilation strategy in which fast growing heterotrophic bacteria directly convert TAN into microbial biomass. The heterotrophic bacteria needs an external carbon source. This study employed polyhydroxybutyrate (PHB) that is a solid insoluble bioplastic, as a carbon source in the aerobic assimilation process to avoid releasing carbon into the system. In order to understand the applicability of an assimilation process instead of nitrification, this study compared the ammonia-N removal rate by aerobic assimilation biofilters operating @ pH 8 and 6.5 in a batch system. The study also quantified the performance of an aerobic assimilation strategy under different continuous nitrogen loading regimes. This investigation can be used to establish the biofilter air pulsing frequency, which is the optimized air pulsing frequency that avoids clogging in the system. The results showed that there was no apparent release of carbon in the water tank. Unlike nitrification, assimilation strategy for TAN removal was not significantly different in two pH of 8 and 6.5 @ 28 ° C. The average consumption rate of the PHB was found as 21.93± 0.43 grams of PHB consumed per gram of TAN. The results from the continuous system, at a continuous feeding rate of 350 mg-N/d, suggested that the optimum air pulsing frequency through the PHB bed for releasing the excess biosolids was about 6-hour. In general, the study found that the aerobic assimilation using polyhydroxybutyrate (PHB) as a carbon source is an applicable method for ammonia-N removal particularly for freshwater ornamental fish production systems. The drawback against this approach is that the PHB beads are expensive. However, our investigations show that the average cost of the PHB beads have been decreased dramatically during the last few years. This might indicate that the assimilation using PHB beads can be a reasonable choice for ammonia-N removal particularly for freshwater ornamental fish production systems.

Web-Based Computational Tools For Studying Plant Biodiversity, Timothy Mark Jones Jan 2014

Web-Based Computational Tools For Studying Plant Biodiversity, Timothy Mark Jones

LSU Doctoral Dissertations

Large scale plant biodiversity bioinformatics projects are now making taxonomic datasets available at a frenetic pace via the World Wide Web (WWW). While these new resources provide the fundamental textual and visual backbone of expert level knowledge, their information structure often impedes the development of derivative works for identification. But when this information is rearranged from a traditional format, questions can be asked of the data that were previously thought to be unanswerable. The difficulty in transforming this ‘big-data’ is manifold: how to deliver it rapidly to researchers across the world while providing visualizations of data that encompass these large …

New Approaches To Smart Grid Security With Scada Systems, Bixiang Tang

LSU Doctoral Dissertations

The use of information technology in electric power grid introduces the vulnerability problem looming the future smart grid. The supervisory control and data acquisition (SCADA)is the first defense, which itself is undermined by potential malicious attacks. This dissertation studies two particular security threats facing the smart grid and SCADA systems: the unobservable attack and the replay attack. The former is well known in fault detection of the power grid and has received renewed interest in the past a few years, while the latter is motivated by the Stuxnet worm allegedly used against the nuclear facilities in Iran. For unobservable attacks, …

The Feasibility Of Creating A 3d Digital Skeletal Collection For Research Purposes And Museum Use, Karen Leigh Beebe

LSU Master's Theses

3D scanners offer many advantages to scientists and museum curators, such as a permanent digital archival record of the scanned object, the non-intrusive nature of 3D laser surface scanning, the ability to create and share a digital collection with other researchers, and the portability of recent scanners. With the purpose of determining the feasibility of creating a 3D research collection in mind, I have scanned and studied skeletal material from Wild Cane Cay and Moho Cay, Belize. I explore how the 3D model compares to the physical bone and the significance of 3D imaging to the anthropological community.
