Offshore Seismic And Fisheries And Environmental Issues - How Can They Be Reconciled?: A Case Study On The Public Review On The Effects Of Potential Oil And Gas Exploration Offshore Cape Breton, David Macdougall

Dalhousie Law Journal

The author describes the review process preceding the 2003 CNSOPB decision which permitted seismic activities offshore of Cape Breton. The process included a public review conducted by Commissioner Dr. Teresa MacNeil and the subsequent establishment of an Ad Hoc Working Group (part of the CNSOPB's existing Fisheries and Environment Advisory Committee (FEAC)) and a Science Working Group reporting to the Ad Hoc Working Group. In the author's view, the Ad Hoc Working Group arrived at the anticipated result; that is, continued disagreement among the opposing parties on the fundamental issues. Consequently CNSOPB was left with the decision on how to …

Walking The Centre Line: Balancing An Employee's Right To Privacy In Drug And Alcohol Policies In The Atlantic Offshore Oil Industry, Harold Smith, Joseph Anthony

Dalhousie Law Journal

Should the principles applied to drug and alcohol testing on land be imported into the Atlantic offshore oil and gas industry? The authors take the position that there is room for the notion that the application of principles derived from safety sensitive land based industry ought not to be applied in a perfunctory or rote manner to the Atlantic offshore environment. The case law, since Entrop, shows a judicial tendency to apply the requirements established by the obiter dictum of Entrop. (Etrop dealt with safety sensitive but land-based industry.) The danger is that the principles, as developed by and since …

Liability For Marine Pollution From Offshore Operations, A William Moreira, Cecily Strickland, David Henley

Dalhousie Law Journal

This paper addresses various aspects of liability for marine pollution arising from offshore operations. The myriad of provincial, federal and international instruments which are relevant to pollution in the offshore generates complex compliance and liability issues. An operator may be subject to both criminal and civil liability for pollution under several different legislative regimes. This paper is divided into two parts. First, compliance considerations are reviewed with the primary compliance requirements under the various acts and regulations applicable to offshore operations highlighted. In the second part, the extent of civil liability for marine pollution is examined.

Deep-Water Turbidites As Holocene Earthquake Proxies: The Cascadia Subduction Zone And Northern San Andreas Fault Systems, Chris Goldfinger, C. Hans Nelson, Joel E. Johnson

Faculty Publications

New stratigraphic evidence from the Cascadia margin demonstrates that 13 earthquakes ruptured the margin from Vancouver Island to at least the California border following the catastrophic eruption of Mount Mazama. These 13 events have occurred with an average repeat time of ?? 600 years since the first post-Mazama event ?? 7500 years ago. The youngest event ?? 300 years ago probably coincides with widespread evidence of coastal subsidence and tsunami inundation in buried marshes along the Cascadia coast. We can extend the Holocene record to at least 9850 years, during which 18 events correlate along the same region. The pattern …

Effects Of Race And Prosecutor's Perceptions Of Victim's Behaviors On Domestic Violence Case Outcomes, Angel K. Williams

Sociology & Criminal Justice Theses & Dissertations

The purpose of this study is to investigate the effects of race and prosecutor's perceptions of victim's behavior on domestic violence case outcomes. This research utilizes data collected by Belknap and Graham (2000) in a large Midwestern Urban area during 1997-1998. Past literature supports the predictions that race and victim's behaviors affect case outcomes. However, there are no studies that examine either race and victim's behavior or the connection between them.

Analyses revealed that victim's race is not significantly related to case outcome. Perceptions of victim's behavior, however, were significantly related to case outcomes. Additionally, prosecutor's race and level of …

Using Optical And Near-Infrared Photometry To Test Macho Lens Candidates, Ted Von Hippel, Et Al.

Publications

We obtained new VLT/ISAAC H-band observations for five MACHO LMC source stars and adjacent LMC field regions. After combining our near-IR photometry with Hubble Space Telescope/PC BVRI optical photometry, we compared the MACHO objects to the adjacent field stars in a variety of color-magnitude and color-color diagrams. These diagnostic diagrams were chosen to be sensitive to our hypothesis that at least some of the MACHO lenses were foreground Galactic disk or thick-disk M dwarfs. For the five lensed objects we studied, our hypothesis could be ruled out for main-sequence lens masses ≥0.1 M☉ for distances out to …

Leadership Style And Performance In Telework: Examining The Influence Of Trust, Rebecca D. Vandever

Psychology Theses & Dissertations

The present study examines the relationship between leadership and performance for teleworkers. Secondary data analysis was used to examine the effects of the Full Range Leadership Theory on the task and contextual performance of 127 teleworkers. Moderated regression analyses show that affect-based trust only moderates the relationship between laissez-faire leadership and task performance. Mediation analyses show that affect-based trust partially mediates the relationship between all three types of leadership and two types of performance. This study shows that affect-based trust is an important element of the relationship between leaders and teleworkers. Future research should further examine the influence of trust …

Characterization And Removal Of Tributyltin (Tbt) From Shipyard Washwasters Laboratory And Full-Scale Studies, Ram Prasad

Civil & Environmental Engineering Theses & Dissertations

Tributyltin has long been used as a biocide in many consumer products to prevent biological growth and fouling. One of the persistent uses of tributyltin is as an antifouling agent in marine paints where its use prevents biological growths on hulls and greatly improves the fuel efficiency of ships. Due to observed adverse effects (tributyltin is an endocrine disrupter) on non-target organisms like shellfish, oysters and snails, the use of tributyltin in marine paints has been banned in many nations and its point source discharge is now regulated through the Virginia Permit Discharge Elimination System (VPDES) program (first state to …

Dissolved Humic Substances: Characterization Of Their Sorption Onto Iron Hydroxide Aluminum Hydroxide Kaolinite And Smectite, Sarah E. Diebel

OES Theses and Dissertations

Humic (HA) and fulvic (FA) acids participate in many geochemical processes and the mechanisms of their sorption to colloidal surfaces are numerous, indicating these substances are complex and heterogeneous. The current study focuses on the interactions of the Fe hydroxide (FE), Al hydroxide, Kaolinite (KA) and Smectite (SM) and these naturally occurring organic acids using Fourier Transform Infrared Spectroscopy (FTIR) and DOC analysis at pH 4. FTIR was used for the initial functional group characterization, as well as the comparison of before and after adsorption spectra of the HA and FA. DOC examined the amounts of HA and FA adsorbed …

Feeding Responses Of Juvenile And Adult Streblospio Benedicti Webster (Spionidae) To Organic Chemicals Bound To Glass Microbeads, Heidi Kathryn Mahon

Biological Sciences Theses & Dissertations

Spionid polychaetes feed at the sediment-water interface using a pair of ciliated palps. Polychaetes select food particles based upon characteristics including size, texture, specific gravity and organic coatings. Juvenile and adult spionids have different stable isotopic carbon signals, indicating the potential to differentiate organic cues ontogenetically. In the present study, the feeding responses of juvenile and adult Streblospio benedicti Webster to seven organic coatings bound (five amino acids and two carbohydrates) to glass microbeads were tested. Juveniles and adults were highly selective for all seven types of organically coated beads. Juveniles were highly selective for threonine; whereas adults were highly …

A Man's Home Is His Castle: A Look At The Relationship Between Fathers And Children In The Novels Of Jane Austen, Miranda M. Johnson-Parries

English Theses & Dissertations

In western society, the father is one of, if not the most, significant roles possible for a man. In the 18^th C bourgeois family, he was especially crucial. In the novels of Jane Austen, the father, even when absent, is a central figure: Dead fathers influence their children by their lack of planning and absence, while a physically present, but mentally distant father has much the same effect. I will analyze how seemingly peripheral male characters within Jane Austen's novels react to their stations in life and try to manipulate them in a similar way to Austen's much analyzed …

A Computer-Based Articulation Training Aid For Short Words (Cata), Mukund Devarajan

Electrical & Computer Engineering Theses & Dissertations

Several improvements in the vowel articulation training aid (VATA) are described, as well as the efforts to extend the visual feedback system to operate with short words in the form of consonant, vowel and consonant (CVC). The extended version of the visual feedback system is referred to as CATA (Computer-based Articulation Training Aid); the vowel version of the aid (VATA) only operates with ten American English monopthong vowels. Improvements in VATA include the use of a neural network (NN) recognizer method to prune a large database of vowel recordings to eliminate noisy and/or mispronounced tokens. The spectral jitter problem, previously …

Brownian Dynamics Simulation Studies Of Ion Throughput During Cellular Electroporation, Juan A. Gonzalez-Cuevas

Electrical & Computer Engineering Theses & Dissertations

The purpose of the present research work is to analyze the flow of ions through pores formed in the plasma membrane of biological cells during electroporation. In this regard, simulations have been conducted to track the movement of ions in 3-D space based on a Brownian dynamics model, which is mostly deterministic but has some stochastic properties to account for ionic scattering. From the Brownian dynamics simulations, it has been possible to estimate the pore's conductance as well as transport parameters such as the diffusion coefficient and mobility within the pore region, of which there is no experimental data currently …

Time Domain Dielectric Spectroscopy Analysis Of Hl-60 Cell Suspensions After Microsecond And Submicrosecond Pulsed Electric Fields, Allen Laurence Garner

Electrical & Computer Engineering Theses & Dissertations

Pulsed electric fields (PEF's) above a certain voltage threshold cause electroporation for microsecond pulses and intracellular effects for submicrosecond pulses. Models describing these effects often depend on the electrical properties of the cell, which are altered by the PEF. Time domain dielectric spectroscopy was used to provide data for these models and to measure changes in the conductivity of HL-60 cell suspensions due to single 50 μs and 10 ns PEF's of the same energy. For 1.1 kV/cm, 50 μs pulses, the conductivity rose within a minute after the pulse and dropped dramatically approximately forty minutes after the pulse. For …

Social Disorganization Theory: Examining The Mediating Effects Of Social Ties And Disorder On Crime, Matasha L. Harris

Sociology & Criminal Justice Theses & Dissertations

Using study data collected for a larger research project entitled Project on Policing Neighborhoods in Indianapolis, Indiana, 1996, the relationship between social ties and disorder on neighborhood structural characteristics and crime rates was tested. Using two Structural Equation Models the mediating effects of social ties and disorder on neighborhood structural characteristics and crime received partial support from the analysis of Indianapolis data.

The results revealed that poverty and family disruption exerts a positive impact on crime rates. The results also revealed that neighborhoods with high levels of racial heterogeneity have a negative effect on social ties. As well, the study …

Single-Walled Carbon Nanotube Bundles Intercalated With Semiconductor Nanoparticles, Manashi Nath, Pallavi V. Teredesai, D. V. S. Muthu, A. K. Sood, Chintamani Nagesa Ramachandra Rao

Chemistry Faculty Research & Creative Works

Nanoparticles of CdSe, CdS and ZnSe have been incorporated in the inter-tubular gaps of single-walled carbon nanotube (SWNT) bundles. Electron microscope, X-ray diffraction (XRD), electronic spectroscopy and Raman studies have been employed to characterize these systems. The lengths of the intercalate inside the bundles could be varied by changing the reaction conditions. Electronic absorption and photoluminescence studies from the semiconductor intercalates show the expected blue-shift with respect to the corresponding bulk samples in CdS and ZnS samples. The SWNT lattice is expanded on incorporating CdSe as confirmed by XRD in the low-angle range. The expansion in the lattice is also …

Resolution Of Multiple Ssdna Structures In Free Solution Electrophoresis, Eve F. Fabrizio, Ali Nadim, James D. Sterling

Business and Information Technology Faculty Research & Creative Works

By using high concentrations of buffer, electroosmotic flow within uncoated channels of a microfluidic chip was minimized, allowing the free solution electrophoretic separation of DNA. More importantly, because of the ability to efficiently dissipate heat within these channels, field strengths as high as 600 V/cm could be applied with minimal Joule heating (< 2 °C). As a result of the higher field strengths, separations within an 8-cm-long channel were achieved within a few minutes. However, when the electrophoretic separation of single-stranded DNA (ssDNA) less than 22 bases in length was performed, containing the fluorophore Texas Red as an end label, more than the expected single peak was observed at this high electric field. On the other hand, the free solution electrophoresis of a double-stranded DNA (dsDNA) consisting of a random sequence did exhibit the expected single peak. The appearance of these multiple peaks for ssDNA is shown to be dependent upon the base content and sequence of the ssDNA as well as on the chemical structure of the fluorophore used to tag the DNA for detection. Specifically, the peaks can be attributed to different secondary structures that result either from hydrophobic interactions between the DNA bases and an uncharged fluorescent dye or from G-quadruplexes within guanine-rich strands.

Exonerations Change Judicial Views On Ineffective Assistance Of Counsel, Adele Bernhard

Articles & Chapters

Law evolves more slowly than pop culture or public attitude. Because most exonerations have not resulted in written legal opinions, their impact is slowly seeping into case law. However, courts are influenced by the same news that sways the rest of us. Even without explicitly referring to innocence or wrongful convictions, modern trial courts are undoubtedly more likely to admit expert testimony on the question of eyewitness identification because they are painfully aware of just how easily such witnesses - no matter how honest or passionate - can be wrong. They are certainly more inclined to view confessions suspiciously, especially …

What Is Wrong With The Homogeneous Unit Principle?: The Hup In The 21st Century Church, Skip Bell

Journal of the American Society for Church Growth

If you find the homogeneous unit principle to be controversial, credit Donald McGavran, who launched the church growth movement with his important work, Understanding Church Growth, first published in 1970. McGavran describes this principle: “Men like to become Christians without crossing racial, linguistic, or class barriers.” What exactly did McGavran and other key church growth researchers mean by this principle?

Of Property And Antiproperty, Abraham Bell, Gideon Parchomovsky

Michigan Law Review

Private property is widely perceived as a potent prodevelopment and anticonservationist force. The drive to accumulate wealth through private property rights is thought to encourage environmentally destructive development; legal protection of such property rights is believed to thwart environmentally friendly public measures. Indeed, property rights advocates and environmentalists are generally described as irreconcilable foes. This presumed clash often leads environmentalists to urge public acquisition of private lands. Interestingly, less attention is paid to the possibility that the government may prove no better a conservator than private owners. Government actors often mismanage conservation properties, collaborating with private developers to dispose of …

The Indulgence Of Reasonable Presumptions: Federal Court Contractual Civil Jury Trial Waivers, Joel Andersen

Michigan Law Review

Large institutions such as banks, franchisers, international companies, and lessors distrust juries' ability to properly resolve disputes and award reasonable damages. As a result, these and other actors have attempted to limit juries' potential influence on the contracts to which they are parties. They have done so through contractual jury trial waiver clauses in these agreements. The Seventh Amendment to the Constitution guarantees the jury trial right. Whether the right is determined to exist in an individual instance is a matter of federal common law, which merely preserves the jury trial right as it existed when the Amendment was adopted …
