Bullying In Schools: The Relationship Between Educational Staff Burnout And Staff Response To Bullying, Katherine Marie Harrison

LSU Doctoral Dissertations

Bullying among school-aged youth is associated with negative short- and long-term consequences. Research suggests that teachers can be influential in reducing bullying but that they often do little to address it. Occupational burnout is high among educators and can significantly affect students’ motivation, learning, and feelings of support. The current study examines the effect of occupational burnout on educational staff’s likelihood of responding to bullies and victims of physical, verbal, relational, and cyber bullying. Participants (N = 109) were administrators, teachers, and other school staff serving secondary-level students. Overall, most participants reported experiencing low levels of burnout, viewed bullying as …

Regulation Of The Chloride Store In The Retinal Amacrine Cells, Vijai Krishnan

LSU Doctoral Dissertations

Nitric Oxide (NO) is a key gaseous messenger that has been shown to be produced by multiple cell types in the vertebrate retina. Research in our lab is aimed at unlocking critical synaptic functions of NO. A major finding from our lab is that NO affects synaptic responses in amacrine cells by altering the plasma membrane gradient for Cl-. This is due to release of Cl- from an internal store and this in turn dependent on a decrease in cytosolic pH. Determining the factors regulating cytosolic Cl- in neurons is fundamental to our understanding of the function of GABAergic and …

Stress Tolerance Enhancement Of Rice By Genetic Manipulation Of A Bhlh-Myc2 Transcription Factor, Luis Eduardo Sanchez Timm

LSU Doctoral Dissertations

Rice yield is adversely affected by various abiotic and biotic stresses. Jasmonic acid (JA) signaling has been implicated in stress response of plants. The nuclear localized basic helix loop helix (bHLH) Myc2 transcription factor is known to be a master regulator of genes involved in the response of the JA-mediated signaling pathway during stress and plant development. Myc2 is also induced by wounding and mechanical damage, and is associated with resistance against herbivore insects. In order to understand the mode of action of Myc2 in stress response of rice, overexpresser (OE) and knock-down (KD) mutants for OsMyc2 were generated in …

An Architecture Of Neuroscience, Josh Donnelly

Architecture Theses

The primary objective of this thesis is to explore how an understanding of neuroscience can influence the human perception of the built environment. Advancement in the field of neuroscience has allowed for a greater understanding of how we perceive the world at a neurological level. An effort to understand our experience of the built environment has been theorized since the time of Vitruvius. This thesis investigates these relationships through an urban in-fill project in downtown Fargo, North Dakota.

Saudade - Rethinking Deathcare, Alex Schrader

Architecture Theses

This thesis explores the manner in which architecture can more sympathetically respond to people in a time of loss and grievance. Through adaptively repurposing a historic structure in Minneapolis, MN, a crematory and funeral home can show an alternative to the current deathcare industry. This alternative is more environmentally sustainable by providing alternatives to harmful cremation and embalming processes, emotionally responsive by creating spaces that encourage the grieving process, and user-focused by providing flexible and innovative spaces which allow for many types of ceremonies.

Reconciling Intellectual And Personal Property, Aaron Perzanowski, Jason Schultz

Articles

This Article examines both the forces undermining copy ownership and the important functions it serves within the copyright system in order to construct a workable notion of consumer property rights in digital media.

Part I begins by examining the relationship between intellectual and personal property. Sometimes courts have treated those rights as inseparable, as if transfer of a copy entails transfer of the intangible right, or retention of the copyright entails ongoing control over particular copies. But Congress and most courts have recognized personal and intellectual property as interests that can be transferred separately. Although the better view, this approach …

Long-Range Atom-Wall Interactions And Mixing Terms: Metastable Hydrogen, Ulrich D. Jentschura

Physics Faculty Research & Creative Works

We investigate the interaction of metastable 2S hydrogen atoms with a perfectly conducting wall, including parity-breaking S-P mixing terms (with full account of retardation). The neighboring 2P_1/2 and 2P_3/2 levels are found to have a profound effect on the transition from the short-range, nonrelativistic regime, to the retarded form of the Casimir-Polder interaction. The corresponding P state admixtures to the metastable 2S state are calculated. We find the long-range asymptotics of the retarded Casimir-Polder potentials and mixing amplitudes for general excited states, including a fully quantum electrodynamic treatment of the dipole-quadrupole mixing term. The decay width of the …

Understanding Longshore Sediment Transport On A Mixed Beach, Inés Martín Grandes

School of Biological and Marine Sciences Theses

The aim of this study is to acquire a better understanding of the short to medium timescale (diurnal to monthly) morphodynamic behaviour of mixed, sand and shingle, beaches. In particular, this project intends to provide a new approach to estimate longshore sediment transport (LST) rates on a mixed beach. In order to do that, the mixed beach at Milford-on-Sea, Hampshire UK, was subject of a novel field experiment consisting on an impoundment technique, where beach profiles were measured daily over two months using RTK-GPS. Meanwhile, the nearshore hydrodynamic conditions were measured collecting wave and tidal data. Then, the short to …

Swash Zone Dynamics Of Coarse-Grained Beaches During Energetic Wave Conditions, Luis Pedro Almeida

School of Biological and Marine Sciences Theses

Coarse-grained beaches, such as pure gravel (PG), mixed sand-gravel (MSG) and composite (CSG) beaches, can be considered as one of the most resilient non-cohesive morpho-sedimentary coastal environments to energetic wave forcing (e.g., storms). The hydraulically-rough and permeable nature of gravel (D50 > 2 mm), together with the steep (reflective) beach face, provide efficient mechanisms of wave energy dissipation in the swash zone and provide a natural means of coastal defence. Despite their potential for shore protection very little is known about the response of these environments during high energetic wave conditions. Field measurements of sediment transport and hydrodynamics on coarse-grained beaches …

Relationships Between Iron, Oxidative Stress, Glycated Proteins And The Development Of Atherosclerosis In Type 2 Diabetes, Husam O. Dakhil Aljwaid

School of Biological and Marine Sciences Theses

Hyperglycaemia stimulates a variety of biochemical abnormalities. The area of particular interest in this study is the influence of non-enzymatic glycation of proteins on iron homeostasis, and particularly on non-transferrin-bound iron (NTBI) and its possible relation to atherogenesis in both Type 2 diabetic and obese non diabetic subjects. The link between non-enzymatic glycation of proteins and iron homeostasis, and development of macrovascular disease may be mechanistically different in Type 2 diabetic and obese non diabetic subjects due to a difference in the protein glycation pattern. Because the following in vivo study required storage of samples for up to two years …

Assessing The Effects Of Long-Term Ocean Acidification On Benthic Communities At Co2 Seeps, Cecilia Baggini

School of Biological and Marine Sciences Theses

Ocean acidification has the potential to profoundly affect marine ecosystems before the end of this century, but there are large uncertainties on its effects on temperate benthic communities. Volcanic CO2 seeps provide an opportunity to examine and improve our understanding of community responses to ocean acidification. In this thesis, two Mediterranean CO2 seeps (Methana in Greece and Vulcano in Italy) were used to investigate the responses of macroalgae and their epifaunal communities to increased CO2. Changes in plant-herbivore interactions at elevated CO2, as well as adaptation potential of dominant macroalgae and responses of macroalgae and epifauna to concurrent exposure to …

The Effects Of Ocean Acidification On Modern Benthic Foraminifera, Laura Rachel Pettit

School of Biological and Marine Sciences Theses

Ocean acidification may cause biodiversity loss, alter ecosystems and impact food security, yet uncertainty over ecological responses to ocean acidification remains considerable. Most work on the impact of ocean acidification on foraminifera has been short-term laboratory experiments on single species. To expand this, benthic foraminiferal assemblages were examined across shallow water CO2 gradients in the Gulf of California, off the islands of Ischia and Vulcano in Italy and off Papua New Guinea. Living assemblages from the Gulf of California did not appear to show a response across a pH range of 7.55 – 7.88, although the species assemblage was impoverished …

Effect Of Mesoscale Variability Of Water Masses On Acoustic Wave Propagation In A Shallow Sea, Feng Chen

School of Biological and Marine Sciences Theses

Anthropogenic noise in the sea is now classed as a pollutant alongside chemical pollution and marine litter in accordance with the Marine Strategy Framework Directive. Noise from shipping is a major contributor to the ambient noise levels in the ocean, particularly at low (<300Hz) frequencies. The properties of sound propagation in shallow waters are highly influenced by the marine physical environment. Ocean modelling plays an important role in underwater noise studies since it can provide high resolution water column parameters over large geographic areas. This study investigates the noise patterns and their temporal variations in the Celtic Sea by using a coupled ocean model (POLCOMS) and an acoustic model (HARCAM). A method to predict noise exposure experienced by marine animals is then developed, following an application for diving seals. The ocean model is applied in the Celtic Sea to provide high-resolution 3D hourly temperature and salinity fields for the acoustic model. The model is validated against in-situ and satellite observations, giving high skills to simulate the water column structures. Sensitivity studies of modelled results to different atmospheric forcing are carried out in order to improve the accuracy of the model. The results show that the modelled sea surface temperature, stratification and water column structures are highly sensitive to the choice of surface forcing, especially in the summer time. The increase in resolution of surface forcing does not necessarily lead to more accurate results. The tidally frontal position is, however, insensitive to the forcing. The variability of noise propagation is studied using the coupled model, demonstrating high dependence on oceanographic conditions, geographic location of sound source and its depth. In summer, when the source of sound is on the inshore side of the bottom front, the sound energy is mostly concentrated in the near-bottom layer. In winter, the sound from the same source is distributed more evenly in the vertical. When the source is on the seaward side of the front, the sound level from a shallow source is nearly uniform in the vertical and the transmission loss is significantly greater (~16dB at 40km distance) in summer than in winter. In contrast, sound energy from a deep source is trapped in the bottom cold water, leading to a much lower transmission loss (~20dB) in summer than in winter. Note that ~10dB fluctuation of sound energy is found during the deterioration of the thermocline in late autumn. Shallow sources (e.g. ships) are sensitive to the surface heat flux as it changes significantly the vertical temperature gradient, while tides play an important role in determining the TL variability of deeper sources (e.g. pile driving) since they cause adjustments of positions of subsurface fronts. The seasonal noise patterns radiated by a large cargo ship are modelled by relating the AIS ship track data and the coupled model, showing a clear influence of the seasonal thermocline and associated bottom fronts on shipping noise distribution. The noise propagates much further (tens of kilometres) in winter than in summer. The predicted shipping noise exposure perceived by grey seals shows strong step changes in the sound level during their descent/ascent through the water column. Since grey seals tend to be benthic foragers, a hypothesis that the step change in sound exposure may have negative impacts on their foraging behaviour is proposed for biological specialists.

Coastal Impacts In The Lee Of A Wave Energy Site: Waves, Beach Morphology And Water-Users (Wave Hub, Cornwall, Uk), Christopher Stokes

School of Biological and Marine Sciences Theses

The Wave Hub facility in Cornwall (South West UK) is a marine renewables test site, predominantly designed for the purpose of trialling wave energy converters prior to commercialisation. Beach water-users such as bathers and surfers are of economic importance to tourism in Cornwall, and during the Wave Hub consultation there were concerns among stakeholders that wave energy extraction would reduce the height and quality of coastal waves for surfing, as well as affecting sediment transport and beach morphology. This thesis investigates the interaction between wave conditions, beach morphology, and beach water-users, and proposes how a wave climate altered by wave …

Managing The Retreat: Understanding The Transition To Salt Marsh In Coastal Realignment Projects, Anissia White

School of Biological and Marine Sciences Theses

Managed realignment is now widely seen as an important part of coastal management strategy, as an environmentally sustainable, cost-effective alternative to traditional, hard defences. However, the trajectory of salt marsh development in managed realignment schemes remains uncertain and it is unclear how sites should be managed to fulfil both coastal defence and biodiversity objectives. In this study, the overarching aim is to find out ways in which we can create salt marshes that are self-sustaining and function as closely to natural ecosystems as possible, by considering the linked biogeomorphological processes in salt marsh ecosystems. Such an approach will improve predictions …

Developing, Using, And Interacting In The Flipped Learning Movement: Gaps Among Subject Areas, Hsin-Liang Chen, Kevin L. Summers

Global Governance And The Reduction Of Poverty And Inequality In The Post-Mdg Era: How Can The Asean-Japan Partnership Contribute?, Fernando T. Aldaba, Rafaelita M. Aldaba

Economics Department Faculty Publications

In 2000, the ASEAN member countries signed the UN Millennium Declaration to eradicate extreme poverty in the world by 2015 through the achievement of the Millennium Development Goals (MDGs). The MDGs represented the global vision of reducing poverty in its various dimensions, and they were mainstreamed in the process of building the ASEAN Socio-cultural Community, which had a similar target date of 2015.1 The new Sustainable Development Goals (SDGs) framework approved in 2015 goes beyond the MDG agenda, which focused solely on poverty, to also include inequality. In recent years, inequality has been worsening amidst rapid economic growth and falling …

A Survey Of Botnet Detection Techniques By Command And Control Infrastructure, Thomas S. Hyslip, Jason M. Pittman

Journal of Digital Forensics, Security and Law

Botnets have evolved to become one of the most serious threats to the Internet and there is substantial research on both botnets and botnet detection techniques. This survey reviewed the history of botnets and botnet detection techniques. The survey showed traditional botnet detection techniques rely on passive techniques, primarily honeypots, and that honeypots are not effective at detecting peer-to-peer and other decentralized botnets. Furthermore, the detection techniques aimed at decentralized and peer-to-peer botnets focus on detecting communications between the infected bots. Recent research has shown hierarchical clustering of flow data and machine learning are effective techniques for detecting botnet peer-to-peer …

To License Or Not To License Reexamined: An Updated Report On State Statutes Regarding Private Investigators And Digital Examiners, Thomas Lonardo, Alan Rea, Doug White

Journal of Digital Forensics, Security and Law

In this update to the 2012 year's study, the authors examine statutes that regulate, license, and enforce investigative functions in each US state. As before, the authors find that very few state statutes explicitly differentiate between Private Investigators and Digital Examiners. There is a small trend in which some states are changing definitions or moving to exempt DE from PI licensing requirements. However, we look at some additional information in terms of practicing attorney exemptions that may cloud the licensing waters.

As with the previous research studies (Lonardo et al., 2008, 2009, 2012) the authors contacted all state regulatory agencies …

On The Network Performance Of Digital Evidence Acquisition Of Small Scale Devices Over Public Networks, Irvin Homem, Spyridon Dosis

Journal of Digital Forensics, Security and Law

While cybercrime proliferates – becoming more complex and surreptitious on the Internet – the tools and techniques used in performing digital investigations are still largely lagging behind, effectively slowing down law enforcement agencies at large. Real-time remote acquisition of digital evidence over the Internet is still an elusive ideal in the combat against cybercrime. In this paper we briefly describe the architecture of a comprehensive proactive digital investigation system that is termed as the Live Evidence Information Aggregator (LEIA). This system aims at collecting digital evidence from potentially any device in real time over the Internet. Particular focus is made …

Identification And Exploitation Of Inadvertent Spectral Artifacts In Digital Audio, N. C. Donnangelo, W. S. Kuklinski, R. Szabo, R. A. Coury, G. R. Hamshar

Journal of Digital Forensics, Security and Law

We show that modulation products from local oscillators in a variety of commercial camcorders are coupled into the recorded audio track, creating narrow band time invariant spectral features. These spectral features, left largely intact by transcoding, compression and other forms of audiovisual post processing, can encode characteristics of specific camcorders used to capture the audio files, including the make and model. Using data sets both downloaded from YouTube and collected under controlled laboratory conditions we demonstrate an average probability of detection (Pd) approaching 0.95 for identification of a specific camcorder in a population of thousands of similar recordings, with a …
