Politics And Aesthetics: Partitions And Partioning In Contemporary Art, Jonathan Owen Clark, Joao Lima Duque
Politics And Aesthetics: Partitions And Partioning In Contemporary Art, Jonathan Owen Clark, Joao Lima Duque
Contemporary Aesthetics (Journal Archive)
Jacques Rancière defined the “distribution of the sensible” as the effect of a type of aesthetico-political decision-making that creates a partitioning of the realm of the perceivable in relation to both art and society. The artworld itself constructs its own particular types of curatorial partitioning: between “art” and “non-art,” between “dominant, residual, and emergent,” and between “mainstream” and “periphery.” This essay examines certain “boundary effects” that develop as a result of the act of the partitioning itself and closely examines what arguably are two new categories in contemporary art: “crossover” and “interventionist.” Both categories have a certain relationship to a …

The Spread Of Exotic Plant Species At Mount St. Helens: The Roles Of A Road, Disturbance Type And Post-Disturbance Management, Lindsey Karr
Environmental Science and Management Professional Master's Project Reports
The landscape of Mount St Helens was dramatically transformed when it erupted on May 18, 1980, creating an outstanding opportunity for ecologists to study succession following a large, intense, natural disturbance. Within the expansive (600 km2) blast area there is varied ownership and a mix of management objectives for the post-eruption landscape. On lands administered by the U.S. Forest Service, there are portions of the blast area that have been designated as a National Volcanic Monument, where the primary management objective is to allow for natural succession to proceed substantially unimpeded. In other areas outside the Monument, salvage …
Plant Response To 14 Engineered Log Jams On The North Fork Toutle River, Wa Sediment Plain, Todd Ashley
Plant Response To 14 Engineered Log Jams On The North Fork Toutle River, Wa Sediment Plain, Todd Ashley
Environmental Science and Management Professional Master's Project Reports
I sought to evaluate the vegetative response to the installation of the 14 engineered log jams (ELJs) on the North Fork Toutle River (NFTR) Sediment Plain. The NFTR sediment plain is constantly being reworked due to channel bank erosion caused by a combination of processes including flow erosion and gravitational mass failure. Vegetation has the ability to protect the bank from erosion as well as providing other stabilizing effects. The ELJ structures were designed in part to protect localized areas of the sediment plain and allow vegetated islands to develop. The purpose of these vegetated islands is to trap sand …

Mathematics and Statistics Faculty Publications and Presentations
For distinct points p and q in a two-dimensional Riemannian manifold, one defines their mediatrix Lpq as the set of equidistant points to p and q. It is known that mediatrices have a cell decomposition consisting of a finite number of branch points connected by Lipschitz curves. This paper establishes additional geometric regularity properties of mediatrices. We show that mediatrices have the radial linearizability property, which implies that at each point they have a geometrically defined derivative in the branching directions. Also, we study the particular case of mediatrices on spheres, by showing that they are Lipschitz simple closed curves …

A Monte Carlo Study: The Consequences Of The Misspecification Of The Level-1 Error Structure, Merlande Petit-Bois
USF Tampa Graduate Theses and Dissertations
Single-case interventions allow for the repeated measurement of a case or participant across multiple time points, to assess the treatment¡͞s effect on one specific case or participant. The basic interrupted time series design includes two phases: baseline and treatment. Raudenbush and Byrk (2002) demonstrated that a meta-analysis of large group designs can be seen as a special case of multi-level analysis with participants (level-one) nested within studies (level-two). Raw data from a set of single case design studies have a similar structure. Van den Noortgate and Onghena (2003) illustrated the use of a two-level model to analyze data in primary …

The edge of the Internet is increasingly becoming wireless. Therefore, monitoring the wireless edge is important to understanding the security and performance aspects of the Internet experience. We have designed and implemented a large-scale WLAN monitoring system, the Distributed Internet Security Testbed (DIST), at Dartmouth College. It is equipped with distributed arrays of “sniffers” that cover 210 diverse campus locations and more than 5,000 users. In this paper, we describe our approach, designs and solutions for addressing the technical challenges that have resulted from efficiency, scalability, security, and management perspectives. We also present extensive evaluation results on a production network, …

Electrical and Computer Engineering Faculty Publications and Presentations
Addition arithmetic design plays a crucial role in high performance digital systems. The paper proposes a systematic method to formalize and verify adders in a formal proof assistant COQ. The proposed approach succeeds in formalizing the gate-level implementations and verifying the functional correctness of the most important adders of interest in industry, in a faithful, scalable, and modularized way. The methodology can be extended to other adder architectures as well.

The effects of forest management on soil carbon (C) and nitrogen (N) dynamics vary by harvest type and species. We simulated long-term effects of bole-only harvesting of aspen (Populus tremuloides) on stand productivity and interaction of CN cycles with a multiple model approach. Five models, Biome-BGC, CENTURY, FORECAST, LANDIS-II with Century-based soil dynamics, and PnET-CN, were run for 350 years with seven harvesting events on nutrient-poor, sandy soils representing northwestern Wisconsin, USA. Twenty CN state and flux variables were summarized from the models' outputs, and statistically analyzed using ordination and variance analysis methods. The multiple models' averages suggest that bole-only …

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 …

Environmental Science and Management Faculty Publications and Presentations
Sampling a whole flora or any significant subset for ex situ conservation purposes is a complex, long-term proposition. Thus, it is important to consider what constitutes an adequate sample not only for all taxa as a whole but also for each taxon individually as well as how to strategically schedule collection over time. There are five basic sampling questions: from which species to collect, from how many and which populations, from how many and which individuals, how many and what kind of propagules to collect, and, finally, at what point is the desired sample size too great for a population …

Increased wildfires and temperatures due to climate change are expected to have profound effects on forest productivity and nitrogen (N) cycling. Forecasts about how wildfire and climate change will affect forests seldom consider N availability, which may limit forest response to climate change, particularly in fire-prone landscapes. The overall objective of this study was to examine how wildfire and climate change affect long-term mineral N availability in a fire-prone landscape. We employed a commonly used landscape simulation model (LANDIS-II) in the New Jersey Pine Barrens, a landscape characterized by frequent small fires and fire-resilient vegetation. We found that fire had …

Small Tidal Channels Improve Foraging Opportunities For Calidris Shorebirds, Aileen K. Miller, Catherine E. De Rivera
Environmental Science and Management Faculty Publications and Presentations
Estuarine intertidal habitats are heterogeneous, therefore migratory shorebirds are expected to forage in microhabitats where they can maximize their energy intake. Identifying proximate factors that migratory shorebirds use to accept or reject a particular habitat patch will help land managers make conservation and restoration decisions that provide the greatest benefits to shorebird populations during migration, a period of intense energy usage. We examined whether small semipermanent tidal channels were preferentially used by foraging Western Sandpipers (Calidris mauri) and Dunlins (C. alpina) during a spring migratory stopover in Bandon Marsh, an Oregon, USA, estuary. Further, we tested …

Understanding the responses of terrestrial ecosystems to global change remains a major challenge of ecological research. We exploited a natural elevation gradient in a northern hardwood forest to determine how reductions in snow accumulation, expected with climate change, directly affect dynamics of soil winter frost, and indirectly soil microbial biomass and activity during the growing season. Soils from lower elevation plots, which accumulated less snow and experienced more soil temperature variability during the winter (and likely more freeze/thaw events), had less extractable inorganic nitrogen (N), lower rates of microbial N production via potential net N mineralization and nitrification, and higher …

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 …

The Sydney Coordinated Adaptive Traffic System (SCATS), an adaptive signal system designed to reduce congestion, has been installed on a heavily trafficked roadway in Portland, OR. In addition to traffic performance metrics, we are investigating how this system affects roadway emissions of air pollutants. A twenty-second reduction to maximum cycle length was proposed for the SCATS system to address pedestrian delay concerns. A two-week trial period with this reduced cycle length was implemented. Travel times and roadside air pollution concentrations were monitored throughout this study period and compared to before and after periods with the current maximum cycle length. Average …

LSU Master's Theses
When Sir Arthur Conan Doyle ended The Final Problem with Sherlock Holmes’ apparent death there was a mass outcry of protest from his fans to the point that myths still circulate about how young Victorian men wore black armbands in mourning. There was a reason why the Holmes stories had such a mass appeal: Sherlock Holmes, brilliant, asexual, emotionally reserved and eminently rational detective that he was, was in many ways the archetype of the ideal Victorian man. As such he struck a very deep chord with British society at the time, the extent of which his creator never quite …

Urban transportation professionals are under increasing pressure to perform data-driven decision making and to provide data-driven performance metrics. This pressure comes from sources including the federal government and is driven, in part, by the increased volume and variety of transportation data available. This sudden increase of data is partially a result of improved technology for sensors and mobile devices as well as reduced device and storage costs. However, using this proliferation of data for decisions and performance metrics is proving to be difficult. In this paper, we describe a proposed structure for a system to support data-driven decision making. A …

Did Schelling Misunderstand Fichte’S Transcendental Method?, Michael Vater
Did Schelling Misunderstand Fichte’S Transcendental Method?, Michael Vater
Philosophy Faculty Research and Publications
The Fichte-Schelling Correspondence interweaves intriguing personal stories and philosophical combat. One of the sadder personal stories involves Schelling getting wind of Fichte’s remark to Friedrich Schlegel that he did not understand transcendental method. The letters document several clumsy attempts by Fichte to minimize the criticism only to have it surface again in a letter Fichte wrote to a former student, Jean Baptiste Schad, who showed the letter to Schelling. In it, Fichte claimed that Schelling understood Wissenschaftslehre no better than Friedrich Nicolai, whom Fichte had publicly excoriated for critiquing as “I-philosophy” a superficial assemblage of random quotes from mixed sources.
Design, Synthesis, And Exploration Of A Chimeric Antioxidant And New Crosslinkers For Molecular Imprinting, Danielle Songe Meador
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
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 …

Hurricane-Induced Geologic Change And Palynological Assessment Of A Rapidly Subsiding Deltaic Environment In Coastal Louisiana, James Dustin Naquin
LSU Master's Theses
This study is focused on a paleoenvironmental history of a backbarrier coastal lagoon situated on the seaward margin of the Lafourche delta lobe in coastal Louisiana. A 2.2 meter long sediment core (Core BC 53) was collected from a mangrove-covered land strip on the northern margin of Bay Champagne, and was studied using pollen analysis, Loss-on-ignition (LOI), X-ray Fluorescence (XRF) analysis, and Cesium-137 and radiocarbon dating techniques to establish sediment stratigraphy and core chronology. Bay Champagne, a backbarrier lagoon formed during the evolution of Bayou Lafourche, has shown to be highly sensitive to geomorphological and vegetation changes induced by sea-level …

Complex correlated electron materials (CEMs), such as transition-metal oxides with exotic properties and novel functionalities, present immense opportunities and formidable challenges in condensed matter physics, materials science, and engineering. These systems are characterized by a multitude of competing ground states that result from the close coupling between charge, lattice, orbital, and spin degrees of freedom, which can be tuned by chemical substitution, strain induction, or by the application of external stimulus (e.g. pressure, temperature, electric, or magnetic fields). Interest in CEMs is fueled by the richness of their novel properties (e.g. Colossal Magnetoresistance (CMR), Quantum Criticality, and High Temperature Superconductivity), …
