abstract:
The Goldboro deposit (16,036,000 tonnes @ 3.78 g/t Indicated and Measured, 5,306,000 tonnes @ 4.68 g/t Inferred, 1,946,100 oz and 798,100 oz Au, respectively) is a Meguma-type orogenic gold deposit in Nova Scotia, Canada. Despite the economic importance of Meguma-type orogenic gold deposits, their origin, paragenesis, and hydrothermal footprint are not completely understood compared to other sediment-hosted orogenic gold districts (e.g., Victorian gold belt, Sukhoi Log). Deposits are hosted within folded metaturbidite successions that consist of repeating fining-upwards successions containing argillite and greywacke. Gold in the deposit is predominantly hosted within quartz veins that lie parallel to bedding, at the contacts between greywacke and mudstone. Four distinct vein generations exist at Goldboro: V1) foliated, bedding parallel, glassy quartz veins that are rich in sulfides, V2) foliated, bedding parallel and discordant milky white quartz veins with abundant arsenopyrite, V3) undeformed, tan, carbonate-rich veinlets, and V4) undeformed, albite+K-feldspar+chlorite+biotite+ilmenite veins. A broad halo of sericite alteration surrounds Goldboro (>100 m from the hinge line of the Upper Seal Harbour anticline) with more localized biotite, chlorite, and albite+sericite alteration. Biotite alteration occurs proximal to V1 and V4 veins (< 2 m), and albite+sericite and chlorite alteration are local to V4 veins (≤2 cm). V2 veins exhibit rare arsenopyrite alteration of the wall-rock, and V3 veins are not associated with any alteration. Lithogeochemistry and mineral chemistry were used to identify vectors
towards mineralization by demonstrating chemical changes within the wall-rock mudstones resulting from fluid-rock interactions during vein-stage mineralization: 1) K₂O and 3K/Al changes reflect the intensity of K-related mica alteration; 2) mass increases in Fe₂O₃ and MgO were found to correlate to biotite and chlorite alteration; 3) mass increases in Na₂O and CaO correspond to albite alteration; 4) Rb, Ba, and Cs were found to be proxies for K₂O; and 5) Sr was identified as a proxy for CaO, and can be used to identify carbonates in V3 veinlets. Gold mineralization is predominantly hosted within V1, V2, and V4 veins as free gold and as cores and inclusions in arsenopyrite. Petrographic textures and mineral assemblages suggest that V4 veins are potentially magmatic-hydrothermal in origin. Vein and mineral parageneses suggest two main mineralizing events, providing evidence for gold remobilization and refocusing, as has been suggested by previous researchers in the Meguma zone.

type: Thesis NonPeerReviewed

abstract:
Located in Trinity Newfoundland, the Admiral’s Point fortifications were constructed by British forces in the mid 1740s. During the British occupation of the site, it underwent numerous changes, being built and improved during King George’s (1744-1748) and the Seven Years (1756-1773) Wars, before being destroyed by the French in 1762. The fortifications were then revived during the Revolutionary period and Napoleonic Wars (roughly 1790s to 1815) before being finally abandoned in the late 1810s. Admiral’s Point represents an important part of Newfoundland’s military and social history as a key defensive feature within the landscape of British settlement on the island; archaeologically, the site contained a significant assemblage of 18th and 19th century material culture. Despite numerous excavations at the site, a comprehensive study of the archaeological features, landscape and artifact assemblage has never been completed.
This project entails a detailed analysis of the material culture dating to the military occupation of the site, a review of documentary sources and a study of the site’s landscape and archaeological features with the aim of creating a more complete understanding of the function that this site played in the 18th and early 19th centuries. Special consideration will be given to the agency of individuals, particularly the enlisted ranks who are often neglected in the sources, both primary and secondary. Consideration will also be given to the often-complex relationship between the civilian and military populations of Trinity. Through this study, our understanding of Admiral’s Point will be situated within the larger context of British North America, showing how the garrison participated in the culture and society of their time.

abstract: This study brings together research from the fields of chronic pain management, complementary alternative medicine (CAM), and somatic practices to enlighten the chronic pain population, massage therapists, and manual therapists about a novel and lesser-known framework of movement principles within the Trager Psychophysical Integration MD method (Mentastics). Mentastics is a set of non-weight-loaded movement combinations (Slade & Keating, 2007), the nature of which is to gently use gravity and one’s own “feeling” of the movements to execute them. This exploratory and descriptive study examined individuals' perceptions of the Mentastics technique to help support people living with persistent chronic pain. Seven participants watched a 15-minute video introducing Mentastics and then participated in an online semi-structured interview, which asked them about their opinions and perceptions of the Mentastics technique video. Four major themes evolved from the participants’ remarks: (1) Mentastics for themselves and others, (2) Mentastics an exploration of movements, (3) Inclination towards positive feelings, (4) Mentastics adaptations. Results have the potential to offer a new way of supporting and offering a lesser-known self-care protocol for mobility maintenance and shaping the future of massage education practices in the field of chronic pain. This study demonstrated the high potential of the Mentastics technique, in possibly aiding with the alleviation of perceived pain levels, within the demographic of individuals dealing with chronic pain.

Masters thesis, Memorial University of Newfoundland.

abstract:
The Island of Newfoundland’s honey bees, Apis mellifera Linnaeus, are relatively disease free compared to other populations and have an exceptional winter survival record. Perhaps these qualities arose due to the Island’s isolation from parasites such as Varroa destructor and lower pesticide use compared to the Canadian mainland. Independently, these two environmental qualities alone should make Newfoundland bees highly desirable to apiarists on mainland Canada. In 1980, due to the increase in Varroa destructor’s decimation of honey bee populations around the world, the Government of Newfoundland and Labrador put into place legislation that prevents the importation of honey bees into the province. Over the last 40 years, commercial and hobby apiculture has increased drastically in popularity, but without the ability to bring in new honey bee stock there is a greater need to understand what lineages and subspecies are currently available to beekeepers on the Island.
The program IdentiFly was used to determine colony lineages and subspecies by analyzing the species-specific vein patterns and wing shapes of honey bee workers. Analysis of wing vein patterns of worker bees has shown variations of honey bee subspecies currently occuring on the Island. The majority of colonies fell into one of two lineages: lineage C or lineage O; most colonies tested were categorized as a hybrid of these lineages. Further analysis suggests that colony subspecies found on the Island include Apis mellifera ligustica, Apis mellifera carnica, Apis mellifera cecropia, Apis mellifera armeniaca, Apis mellifera meda, and Apis mellifera scutellata. Subspecies population percentages vary across the Island due to local selection, the combination of
natural and artificial pressures on colony survivability. A majority of colonies were identified as the Armenian honey bee, A. m. armeniaca. This suggests the adaptative advantage this specific honey bee subspecies has in relation to the influences in Newfoundland and mainland Canada.

abstract:
Objective: To determine the wait times for service for hereditary cancers and cardiac disease, as well as the barriers that exist that impact wait time. Background: Access to genetic testing and services is currently largely restricted for practitioners outside of the medical genetics specialty within Newfoundland and Labrador. The current practice may delay timely access to care that is required to diagnose and develop a plan of care. Methods: Data was extracted from 78 patient referrals received in the Provincial Medical Genetics Department (PMGP) from January 1 through December 31, 2013. Charts were evaluated to establish the timelines for access to services, with an examination of the timelines for each phase of the process. Semi-structured interviews with nine key stakeholders were completed to gain an understanding of their role in the patient pathway, as well as the expectation of the service. Results: There is a non-significant difference in the median wait time to receive service between cancer and cardiac referrals with a wait-time of 45.7 months (95% CI 41.8 – 49.5) for cancer versus 36.5 months (95% CI 22.7 – 50.3) for cardiac referrals. Of the 78 patients in the sample, 9 (12%) did not require an appointment but remained in the queue, and 11 (14%) were a “no show” or refused an appointment. The referral triage process did not impact time to receipt of services, with a median wait time of 43.6 months (95% CI, 38.9 – 51.3) for referrals that were triaged and 45.7 months (95% CI 40.9 – 50.4) for those not triaged. To assist with the triage process additional information was required for 33 of the 78 referrals, 17 (51.5%) patients returned this information, while 16 (48.5%) did not. Wait time for service was not impacted, as all referrals received an appointment. There was no significant difference in wait times between internal or external referrals, median wait time 45.7 months(95% CI, 38.2 – 53.1) for internal referrals, versus 44.1 months (95% CI, 36.9 – 51.3), however, referrals from families had a wait time of 3.4 months (95% CI, .18 – 6.6). Qualitative analysis of semi-structured interviews that were
completed with nine health care providers suggests that the major barriers for access were the current referral process, prolonged wait times, lack of referral appropriateness knowledge, and the inability of the provider to order baseline genetic testing. Conclusion: Genetic counseling and treatment are complex processes. The current referral process is prolonged. Survey respondents indicate a low satisfaction, and frustration with the disjointed process. A streamlined standard process would enable the PMGP to better control the flow, to ensure time to access and service is decreased for the highest priority patients.

abstract:
Over the past 20 years, nanoparticle (NP) investigations by single entity electrochemistry (SEE)
have become increasingly popular owing to simultaneous acquisition of both catalytic and
dynamic NP information. Typically, NPs travel through solution under Brownian motion. When
metal NPs randomly collide with an ultramicroelectrode (UME) they can usually be detected
through either of two charge transfer processes: (i) complete oxidation of the NP or (ii)
electrocatalytic amplification (ECA). In the latter, the metal NP acts as a catalytic surface lowering
the driving force of reaction (i.e., necessary applied potential), greatly enhancing the measured
current signal. Owing to their random motion, NPs impact the surface and then move way or are
consumed which generates a ‘current spike’ with a characteristic profile in the recorded
chronoamperogram (i-t curve). Herein, Pt and LiBH₄ nanocrystals (NCs) prepared in
trihexyltetradecylphosphonium bis(trifluoromethylsulphonyl)imide (P₆₆₆₁₄NTf₂), an ionic liquid
(IL), were studied at both solid/IL (UME) and soft (water|IL) micro-interfaces. Pt NPs showed
electrocatalytic activity for borohydride oxidation reaction (BOR) and methanol oxidation reaction
(MOR) through ECA. Also, this method was used for calculating the size of LiBH₄ dielectric
nanocrystals (NCs) by integrating the i-t curve beneath the current spikes, which compared
favourably to NP sizes determined from TEM micrographs.

Masters thesis, Memorial University of Newfoundland.

abstract:
The genetic relationship, if one exists, between magnetite-(apatite) (MtAp) and iron oxidecopper-
gold (IOCG) deposits has been debated for many years, and to this day, few
representative places have been found where both types of mineralization occur. The Jurassic age
Montecristo district in northern Chile is one of a few places in the world where both MtAp and
IOCG mineralization occur with vertical and crosscutting relationships. Consequently, this is one
of the best sites to better understand the possible relationship between these two types of
mineralization and their formation, and is the main objective of this thesis project. For this
project, the samples studied were selected from: (1) a MtAp vein (the San Juan vein), comprising
magnetite, and pegmatite-like fluorapatite, and actinolite; (2) a vein with MtAp mineralization in
the deeper parts of the system, and an overprinting IOCG assemblage of chalcopyrite, pyrite,
magnetite, actinolite, quartz, gold, and molybdenite, in the shallower parts of the system (the
Abundancia vein); and (3) the host rock that contains both types of mineralization.
The results of this study reveal that the host diorite, the MtAp mineralization in the
Abundancia and San Juan veins, and the IOCG mineralization, are all coeval within error, and
that their genetic relationship cannot be discriminated by geochronology alone. However,
intermediate εNdi values of the IOCG event suggest a mixing of Nd from the MtAp rocks and a
deep magmatic-hydrothermal source. Hf, Sr–Nd, and sulfur isotopes support a model in which
the IOCG mineralization was derived from magmatic-hydrothermal fluids. We propose that an
ascending, immiscible iron-rich melt utilized structures of the Atacama fault system as pathways
for the deposition of the MtAp mineralization, followed by precipitation of the IOCG sulfidemagnetite-
actinolite-quartz-gold assemblage from magmatic-hydrothermal fluids that used the
earlier MtAp rocks as a trap.

Masters thesis, Memorial University of Newfoundland.

abstract:
The rainbow smelt (Osmerus mordax) is the most abundant and widespread forage fish residing within the Lake Melville estuary, Labrador, and plays a key role in the upcycling of energy from lower trophic levels to top predators. Rainbow smelt is an abundant prey for a myriad of animals, such as salmonids, gadids, flatfish, birds, and marine mammals, and is one of the preferred wild-caught fishes for subsistence and recreational fisheries in the region. The phenology, including spawning, of rainbow smelt is attuned to the hydrography of the Lake Melville estuary. For example, both spawning and hatching periods coincide with increased water temperature in the spring. With the completion of a new hydroelectric dam in Lake Melville’s main tributary, the Churchill River, a modification to the natural flow regime of freshwater into the estuary is expected. Following the demand for electricity, the Churchill River will likely experience lower than normal runoffs in the spring and summer and higher than normal flows in the fall and winter, when demand for power is higher. Modifications in the inflow of freshwater in Lake Melville can result in temperature variations and change the timing of ice formation and break-up as well as the total duration of ice cover within the estuary. Such changes to the natural flow and hydrography can impact the life history of rainbow smelt, especially given that Lake Melville is at the northern limit of the distribution range of the species. Here, I examine the period of spawning and hatching, and variation in abundance of larvae in relation to temperature and salinity. Additionally, I document larval growth as well as the age structure, growth, and maturation of adult rainbow smelt in an effort to understand how the new hydroelectric facility and a changing climate may impact rainbow smelt phenology. Larval growth rate is up to 3.33 times faster than that of more southern regions, while the spawning season and hatching period occurred later, which is hypothesized as being a result of the shorter growth season prevailing at high latitudes. In contrast to early life
iii
stages, our findings confirm that adult rainbow smelt grow slower, mature later, and live longer in northern populations compared to southern populations, which is likely due to lower metabolic rate in colder waters prevailing at high latitudes. This thesis contributes to the relative scarcity of information on the life history processes of rainbow smelt in this region. These gaps in basic life history information hinder data-driven management decisions on population status and vulnerability. Additionally, this study provides important baseline information which can be referenced in future studies examining the impact of hydroelectric dam operation on the life history of rainbow smelt and, in turn, ecosystem health due to the species’ ecological importance.

abstract:
The daily activities associated with the 17th-century cobblestone street at Ferryland,
NL are analyzed here through an examination of architectural remains and material culture.
Guided by built form and taskscape theories, this research will help interpret how the
residents of Ferryland interacted with each other, and with the different industries set up
around the street. Early modern streets were both public and private areas, and along with
roadways were not uncommon in English colonies. But this paved street—13 feet (4 m)
wide by 400 feet (121 m) long—is one of the oldest examples known in North America,
and one of Ferryland’s most distinctive features. Research reveals that the street was built
within the first decade of the colony’s founding in 1621 and was in use throughout the
century and, to a lesser extent, even after the colony’s destruction in 1696. Although the
street functioned as the spine of the Ferryland colony, with most of the settlement closely
adjacent to it, very little research has been conducted in regards to the street itself since it
was uncovered in 1994. This project seeks to show how the idea of permanent settlement
was reinforced by this large-scale construction, how the street adapted to changes within
the colony and even survived it, and how the street shaped and was shaped by the day-today
interactions of those who lived and worked in 17th-century Ferryland.

abstract:
The emerging communication networks generate a huge amount of data that need to be
aggregated/disseminated, processed, and responded to in a very short time. Major challenges
associate with the need to handle such tremendous amount of data, including high
energy consumption, larger delay, and constrained computation capabilities. Consequently,
more efficient frameworks could be exploited for data aggregation, dissemination, and processing.
This work aims to design energy-efficient and age-optimum frameworks for data
aggregation/dissemination. Moreover, reliable and low latency offloading frameworks for
sequential and parallel mobile edge computing (MEC) offloading are also developed. A
device-role assignment framework is designed to optimize the role of each device in the
network and enable in-network data processing. More sophisticated scenarios with mobile
data aggregator/disseminator are explored as well. Mobile data aggregator(s)/disseminator(s)
for terrestrial and underwater scenarios are considered. Different metrics are studied including
the overall energy consumption in the data aggregation/ dissemination systems,
age-of-information (AoI) in the data aggregation systems, and the latency and offloading
error in the MEC systems. A novel metric referred to as the correlation-aware AoI is
also proposed to captures both the freshness and diversity in the aggregated data. Computationally
efficient solution approaches are developed to find solutions for the proposed
frameworks, including genetic algorithms, ant colony optimization, conflict graphs, and
deep reinforcement learning agents. To show the effectiveness of the developed solution
approaches, their performance is compared to baseline approaches. Extensive simulations
show that the proposed solution approaches provide performance close to the optimal solutions,
which are obtained through exhaustive search or computationally intensive methods.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract:
A central focus of trait-based ecology is investigating trait-species-environment relationships. Across landscapes, foliar traits of forest species are influenced by environmental conditions that result in spatial patterns of trait variability. In this thesis, using commonly occurring boreal plant species, I infer ecological processes from the empirical spatial patterns of foliar elemental (i.e., carbon (C), nitrogen (N), and phosphorus (P)), stoichiometric (i.e., C:N, C:P, and N:P), and phytochemical traits (i.e., terpenoid concentrations of coniferous species); herein referred to as foliar ESP traits. In this thesis, I first investigated how the elemental niche of a conifer and deciduous species differ at a species level between ecoregions and at a community level across, within, and between ecoregions. Notably, I found that a species foliar elemental niche is specific to their biogeographic location, suggesting that regional environmental factors constrain eco-physiological processes that influence how species acquire and use elemental resources. Secondly, I compared multiple models to determine parsimonious predictors of foliar ESP traits using combinations of spatial covariates which include land cover (i.e., coniferous, deciduous, mixedwood), productivity (Enhanced Vegetation Index), biotic (stand height, canopy closure, age), and abiotic (elevation, aspect, slope) factors. I found that spatial-trait relationships occurred at the species level. These results suggest that the spatial patterns of foliar ESP traits are largely species-specific at the landscape extent. Thirdly, at the forest stand extent, I examined the spatial co-variance of foliar ESP traits between species. I found that in most cases, spatial correlations of foliar ESP traits differed between forest stands and that spatial aggregation/segregation patterns of foliar ESP traits varied with distance/direction. Notably, most foliar phytochemical traits of conifers exhibit strong aggregation at a close distance (0-50 metres). Finally, I summarized the main thesis takeaways that (1) foliar traits differ by biogeographical locations and in response to common community-level configurations, (2) the spatial predictors of foliar
traits are species-specific, and (3) the spatial co-variance patterns of foliar traits are scale, site and species-dependent. My thesis contributes to our understanding of how traits can be used to inform different aspects of landscape functionality by bridging community, ecosystem, and landscape ecology disciplines.

abstract:
Direct liquid fuel cells (DLFCs) are a candidate technology for sustainable power generation
with high energy efficiency. Among renewable liquid fuels (e.g. ethanol, methanol and formic
acid), bioethanol is the most attractive liquid fuel because of its low toxicity and high energy
density. However, Pt anode catalysts for ethanol oxidation face problems, such as large
overpotential (causing the decrease of fuel efficiency) and catalyst poisoning (leading to severe
current decay). In order to improve catalyst performance, one strategy is to introduce metal oxide
supports. Nevertheless, the support effects of metal oxides prepared by different methods could
not be fairly evaluated and systematically compared due to a wide range of particle sizes and
different structures. Therefore, a consistent method should be used for preparation of metal
oxide-supported catalysts.
Thermal decomposition of M(acac)x complexes (acac = acetylecetonate) was investigated as
a versatile method to rapidly prepare metal oxide supports (e.g. Ru oxide, Sn oxide, and mixed
Ru-Sn oxides, Pb oxide, Mo oxide, Ga oxide, In oxide, V oxide, and Zr oxide) on Ti foil.
Preformed Pt nanoparticles were drop coated onto the metal oxide supports, so that the
morphology, size, and composition of the Pt were kept the same. Cyclic voltammetry was used to
quickly investigate the influence of the metal oxide supports on catalytic activity of the Pt
catalyst in ethanol oxidation. Charge transfer between metal oxide supports and the Pt
(electronic/ligand effect) was analyzed using X-ray photoelectron spectroscopy. These metaloxide
supported catalysts were quickly prepared and screened on Ti electrodes for oxidation of
ethanol.
The methodology of M(acac)x thermal decomposition was further applied to a carbon
support with a high surface area, so that the prepared anode catalysts can be used in proton
exchange membrane (PEM) cells for ethanol oxidation. Online detection of the amount of CO2
produced from complete oxidation of ethanol in the PEM cell was developed using a nondispersive
infrared CO2 sensor. Therefore, the influence of M(acac)x modification on the CO2
yield could be evaluated. In addition, the enhancement of Pt-catalyzed oxidation of methanol and
formic acid through modification with some M(acac)x was also investigated.

abstract: Atlantic salmon (Salmo salar) by-products are sources of valuable bioactive compounds such as amino acids, peptides, enzymes, collagen, and omega-3 fatty acids. Due to high perishability, leading to spoilage and loss of quality, fish by-products end up in low value products such as pet food or fertilizer. Microbial spoilage, autolysis, and lipid oxidation are the main degradative processes that occur in fatty fish. In order to optimize their use in higher value products, the degradation occurring in the salmon by-products during storage should be controlled. Adequate processing before storage is required in order to avoid the degradation of the bioactive compounds present in the by-products. The main aim of the present study was to evaluate the effect of the presence of reactive organs (which could enhance lipid oxidation) and processing methods during storage for the stabilization of Atlantic salmon (Salmo salar) by-products against lipid oxidation and their subsequent utilization for the extraction of high-quality bioactive compounds. The present study investigated the effect of the presence of reactive organs including gills, heart, liver, bile sac, kidney, spleen, swim bladder, and gonads. In parallel, the effect of grinding and tumbling processing methods was investigated to stabilize and increase the storage time of by-products. The lowest lipid oxidation was obtained using tumbling in the absence of reactive organs. Tumbled by-products without reactive organs were stored at -18˚C, and the protecting effect of the addition of an antioxidant against lipid oxidation of by-products using tumbling and grinding. The fatty acid profile analysis was performed on the oil extracted from frozen samples, and the oxidation of the lipids was studied. A promoting effect of lipid oxidation was observed in the ground by-products, significantly affecting viscera's lipid oxidation and hydrolysis. Salmon heads, frames, and viscera without reactive organs were stable during storage regardless of added antioxidant or the processing method (except for ground viscera). The fatty acid analysis showed five primary fatty acids present in the polyunsaturated fraction of the oils from heads, frames, and viscera: linoleic acid, alpha-linolenic acid, docosahexaenoic acid, eicosapentaenoic acid, and docosapentaenoic acid. The PUFA content remained stable during storage at -18˚C in ground and tumbled by-products with and without addition of antioxidant. However, the amounts of EPA and DHA in the present study were lower (from 3.58 to 5.7 g/100 g) compared to similar studies performed in Atlantic salmon by-products probably due to lower quantities of EPA and DHA present in the fish diet. The lipid stability of by-products containing higher levels of EPA and DHA should be investigated.

abstract: The engineering problem presented in this paper is the design of LARVA, a new launch and recovery vessel for the Memorial Explorer AUV. The solution detailed in this report is one which is modelled after a heavy lift vessel. It is a 19ft long, unmanned vessel and is capable of launching or recovering the AUV by ballasting itself to a 3.7ft draft and raising itself back up. The innovative aspects of this design is that it was designed to be used with a readily available boat trailer for launch and recovery with a slipway. The concept solution was analyzed using hydrostatics analysis software to assess its stability and to aid in the process of positioning and sizing the ballast tanks. A motion tracking system was used during model testing to assess its seakeeping ability in offshore waves and an analysis of variance test (ANOVA) was conducted to: capture the dependency between the input parameters, reduce the number of runs required, and to generate a response surface characterizing the heaving motions.

abstract:
A ship accident in the Arctic poses risks to the crew and passengers, the environment,
Arctic communities, and other Arctic stakeholders. There are life-safety, ecological, and
socio-economic consequences that require consideration in the operational risk
management and regulation of Arctic ships. The objective of this thesis is to contribute to
safe and efficient Arctic maritime operations. A scenario-based Arctic shipping operational
risk management framework is proposed that integrates life-safety, ecological, and socioeconomic
consequences into the Polar Operational Limit Assessment Risk Indexing
System (POLARIS) regulatory guideline. The proposed framework is then developed
further. First, a scenario-based life-safety consequence model for Arctic ship evacuations
is developed through elicitation of expert knowledge. Then a consequence aggregation
method is developed to combine life-safety and environmental consequences of an Arctic
ship accident. The development of regulations requires evaluations of the costs associated
with regulatory implementation. Complementing the proposed augmentation of POLARIS,
a general method to evaluate the operational implications incurred under maritime
regulatory constraints is developed. The method combines a ship performance model,
regulatory constraint models, and pathfinding and optimization algorithms. Results of the
research show that the consequence severity of an Arctic ship accident depends on ship
type and accident location. Worst-case scenario ship accidents are those involving cruise
ships in regions associated with long response times and oil tankers in environmentally
sensitive regions. With respect to the operational implications of regulatory constraints,
POLARIS offers operational flexibility over the Arctic Ice Regime Shipping System
(AIRSS), but is associated with increased voyage time and fuel consumption. Implications
for safe and efficient Arctic maritime operations can be drawn from the research. Vessels
that pose higher life-safety and environmental consequences should be operated more
conservatively. Continued enhancement of Arctic SAR services and advanced training for
all Arctic seafarers will contribute to the mitigation of life-safety risk posed by Arctic
shipping. Mitigating the risk associated with Arctic cruise operations is of near equal
priority to that of Arctic tanker operations. POLARIS and AIRSS are decision-support
tools that support safe Arctic navigation but should not replace competent Arctic crews.

abstract: This research focuses on sexual assault in medieval England by examining twelfth to fourteenth-century trial records, England's medieval rape laws, and literary representations of rape in popular Middle English romance. By comparing representations of rape in romance, with contemporaneous trial documents, and the laws themselves, this dissertation argues that in medieval England, consent and non-consent to rape were based on the physical proof of resistance on the woman’s body. This is the body of proof. Analysing the five legal ages of England’s raptus laws, from Glanvill to the Statute of Rapes, it is evident that the gradual displacement of victim status away from the woman herself and in favour of her male kin was in response to continual frustration with the marriage clause and a persistent fear of malicious accusations of rape. This is represented not only in the laws themselves, but also in popular romance narratives. The analysis of previously unpublished twenty-eight cases from the court of the general eyre exposes a schism between the laws in theory and in practice. By combining these with an ecclesiastical perspective, as well as popular romance narratives, the research suggests that there were three constructed legal identities a woman could have had when appealing rape: the truly innocent victim, the reluctant but willing accomplice, and the scheming culpable woman. Through a comparison to popular romance narratives with scenes of rape and sexual violence, it is evident that these identities were not confined to the courts, but widely acknowledged in medieval English culture. The evidence suggests that there are remarkably consistent cultural tropes used in reference to survivors of sexual assault from the Middle Ages through to the twenty-first century. Ideas around "no means yes" and that the body can enjoy the assault are exposed in this research as existing in English medieval culture. In looking at rape laws, how the laws were interpreted by the courts through actual trial records, as well as the social attitudes towards rape as represented in popular romance narratives, this research presents new understandings of the cultural and legal discourse of rape in medieval England.

abstract:
The purpose of this thesis was to review how a simple clinical pediatric orthopaedic surgeon
might be able to create and use different levels of Evidence Based Medicine.
Practicing evidence-based medicine involves the assessment of current available literature for its level of evidence, validity, and significance; and subsequently applying results to clinical practice. Much of the literature in pediatric orthopaedic surgery is level IV (case series) or level V (case reports). Despite the lower level, this literature is still important for reporting adverse events and disseminating information of novel treatment techniques.
A case report of a novel adverse event is presented: permanent physeal arrest from the use of eight plate for guided growth. Following, a case series aimed to assess if the Fitbone intramedullary lengthening nail could provide successful lengthening with improved
rehabilitation and minimal hospital stay, while achieving therapeutic aims of lengthening and correcting mechanical axis. Thirdly, one year of publications in 3 highly respected pediatric orthopaedic journals was reviewed. The use of “numbers needed to treat” as an adjunct to statistical analysis and level of evidence was determined for each article. And finally, a systematic review of the literature looks at the incidence of venous thromboembolism in pediatric orthopaedics. This study began with a stringent, comprehensive
protocol that detailed the plan and search strategy. Initially, a meta-analysis was planned, but due to the level of evidence of the articles included, only descriptive statistics could be used.
The many setbacks and delays demonstrated the difficulties in producing literature. A case study, case series, review of use of the statistical analysis Number Needed to Treat, and finally, a
systematic review were produced.

abstract: There is little known about the importance of women’s identities in terms of both their familial domains and their male-dominated career domains, which have contradictory role demands. In this thesis, I build on the literature about positive social identities in organizations through linking married women who work in male-dominated industries and their self-views regarding their spousal and career identities. I propose that identity conflict mediates the effect of positive spousal and career identities such that when women hold favorable regard for their social identities in their marriage or their career, they experience reduced identity conflict and subsequent increased psychological well-being, career commitment, and relationship satisfaction. I explore spousal support as a moderator whereby when women in male-dominated industries have higher levels of spousal support, their positive identities will further reduce their experiences of identity conflict, leading to higher levels of well-being, relationship satisfaction, and career commitment. The results indicate that women’s positive spousal and career identities are negatively associated with identity conflict. Identity conflict is subsequently negatively associated with psychological well-being and relationship satisfaction. Additionally, both positive career identity and positive spousal identity were found to have a positive indirect relationship with psychological well-being. The moderating role of spousal support was non-significant. Theoretical contributions, practical implications, and an agenda for future research are discussed.

abstract: The concept of the Pavement Management System (PMS) is to assist transportation agencies in making well-informed decisions utilizing pavement-related data and technical expertise. Canada has over 1.13 million kilometers of roads (two-lane equivalent km), which is the seventh-largest road network in the world. Approximately 80% of public roads in Canada are governed by the regional authorities, which refer to cities, towns, and municipalities, making them the most important contributors to the Canadian road management system. Based on the objective and scope of the agencies, the process of implementing the PMS varies. Regional authorities manage low-traffic roads exclusively, and they often lack resources, technical people, and budget. Therefore, it is extremely important to utilize these limited resources and budgets to make efficient decisions. This study represents a PMS framework for the agencies that own low-traffic roads, have resource shortage, and budget constraints. As part of this research, three different surveys were conducted with a view to understanding: PMS practices throughout the country, PMS practices in the municipalities within Newfoundland and Labrador, and road user's feedback on roadway asset conditions. A new PMS framework is proposed using the data from the surveys and following an exclusive literature review on PMS. Finally, municipalities of Newfoundland and Labrador are considered as a case study to apply the proposed framework after an extensive study on these municipalities.

abstract: Modern wind turbines are generally used for electricity generation; however, the final form of energy required by many users is thermal energy. Although electrical energy conversion to thermal energy is a high-efficiency process, the efficiency of electricity generation from wind turbines is usually low. In this thesis, a heat generator with fluid agitation is developed and studied. This heat generator converts kinetic energy (e.g. that from a wind turbine) directly to thermal energy through the process of viscous dissipation; this process is achieved through the agitation of the working fluid inside a container. This heat generator uses an optimized flat blade turbine (FBT) impeller and a fully baffled configuration. An electric motor is used to provide the kinetic energy input to the heat generator. A torque sensor, a tachometer, and thermocouples are used to measure the torque, rotational speed (RPM,) and temperature rise in the fluid, respectively. Using the measured quantities, the efficiency of kinetic energy to sensible heat conversion is calculated. Experiments are conducted at different rotational speeds and for different working fluids: distilled water, ethylene glycol, and their respective nanofluids with Al₂O₃ nanoparticles at different concentrations. The experimental results indicate that the heat generator is up to 90% efficient in converting kinetic energy to thermal energy. The temperature rise rate increases with the rotational speed and larger diameter of the impeller. Furthermore, the addition of nanoparticles improves the thermal properties of the fluid, but it does not significantly affect the energy conversion efficiency or the rate of temperature rise in the fluid. A wind turbine can power this heat generator to provide heat to a house or a commercial building. This innovative renewable energy technology would benefit wind rich remote areas with cold weather.

Masters thesis, Memorial University of Newfoundland.

abstract:
This study is primarily aimed to identify distinct subgroups of individuals following similar
mental health conditions over a 16-year follow-up using the latent class growth modeling
(LCGM). We also provided the description of characteristics of each trajectory group.
Mental health trajectory analysis can show the long-term age-related developmental changes
of young adults (18-29 at baseline) and older population's (60-75 at baseline) mental health
condition.
The National Population Health Survey (NPHS), from 1994 to 2011 was used for this study.
The results showed that the mental health conditions among the survey population during the
follow-up period were not homogeneous, and there existed several common group patterns of
mental health conditions at different age groups. The young adult group consisted of 2661
subjects, ranging from 18 to 45 years of age; while the senior group consisted of 2036
subjects, ranging from 60 to 91 years of age. Four trajectories were identified among the
young adults' population, and two trajectories among the older population. Mental Health
trajectory group memberships were related to numerous variables, including sex, socialeconomic
status, lifestyle, as well as physical conditions. Through analyzing trajectories and
attributes of different trajectories, this study might contribute to understanding the
psychological conditions of the Canadian population.

abstract:
The time-lapse or four-dimensional (4D) seismic method is used to image subsurface
changes within a reservoir through acquiring multiple three-dimensional (3D) seismic
surveys over the same area some time apart. The concept extends from the assumption
that any changes in the seismic signal between surveys are due to perturbations in
subsurface properties (i.e. fluid saturation, pressure, and temperature) caused by the
production of a reservoir interval. In this thesis, we determine velocity estimates for a
synthetic production-related time-lapse seismic anomaly in the Pool 1 reservoir of the
Hebron Field located within the Jeanne d’Arc Basin, offshore Newfoundland, Canada.
We use a time-lapse seismic uncertainty quantification algorithm to compute 1,000,000
velocity estimates of the time-lapse seismic change in the Pool 1 reservoir. We compute
these models across four Markov chains with an acceptance rate of 13.5 - 16.0% in 5.4
days on a standard desktop (i7 6700 3.4 GHz processor and 16 GB memory). Repeated
sampling generates end ranges of possible velocity models representing the synthetic
production-related time-lapse change created for Pool 1 in this thesis. Quantities of
interest (QoI) are defined to highlight the ability of these velocity models to represent
the size and magnitude of the true synthetic production time-lapse change. We plot
statistical versions of the velocity models recovered by an arbitrary Markov chain to
visually showcase the recovered mean and maximum likelihood model representations
of the true synthetic time-lapse velocity perturbation.

abstract: This thesis explores the use of multi-objective optimization algorithms for the design of high frequency inverters. A state-space model of the ideal Class-EF₂ inverter is derived and its accuracy is validated by MATLAB and LTSpice simulation. The model is then applied to the Multi-Objective Genetic Optimization (MOGO) and Multi-Objective Particle Swarm Optimization (MOPSO) algorithms to design three inverters with varying output power, frequency, and load requirements. The final designs are compared with analytical results to verify the optimization-based design approach. The ideal state-space model is then extended to include the parasitic elements of components, and further extended to consider the internal resistances and capacitances of the switch. These new models are applied to the MOGO and MOPSO algorithms to design the same three inverters as the ideal case. The final designs are simulated in LTSpice to evaluate their performance, and comparisons are presented to demonstrate the effects of the parasitic elements and switching dynamics on the component values and overall circuit operation. A design example is also presented to demonstrate the design of a 6.78 MHz, 100W, 20 Ω Class-EF₂ inverter, and provide designers with insight on how to apply the proposed design approach to their own designs.

abstract:
Biofouling, the accumulation of organisms on submerged aquatic surfaces, can be detrimental to the aquaculture industry. In the Atlantic Canadian provinces, excluding Newfoundland and Labrador (NL), fouling by aquatic invasive tunicate species has had large economical impacts on the mussel aquaculture industry. In NL, invasive tunicates have not necessitated management, control, or removal at mussel aquaculture sites, but prevention is an important management tool.
Antifouling coatings can prevent the movement of native and invasive species from a support harbour to a site. In a field study, different antifouling coatings, with different antifouling properties, (chemical and mechanical) painted on wooden panels, were submerged in coastal outports to determine the effectiveness of the coatings in the NL marine environment. A laboratory study was also conducted to determine if micro-surface topography of a coating differed amongst coatings.
Coatings which contained biocides, such as Econea®, and copper and zinc, prevented biofouling accumulation for a period up to 12 months, post-deployment. Among all sites, Micron CF (Econea®) had minimal biofouling accumulation after the first year (less than 5%) and by the end of the trial had less than 60% of the area settled by fouling organisms. Foul release coatings (e.g., Hullspeed 3000) were not effective in this application. Scanning electron microscopy images showed varied textures, in structure and volume, between the different types of antifouling properties, which may promote or prevent initial settlement. All properties together are important to the efficacy of an antifouling technology.
In the aquaculture industry, where vessels are not moving great distances between the docks and the farms and where operations often require vessels to move slowly to complete various work on the farm sites, the use of ecofriendly biocide antifouling coatings (e.g.,Micron CF) would be the best defense against the movement and spread of fouling organisms and aquatic invasive species.

abstract:
This thesis explores the development of protection and support efforts to address labor trafficking from the Philippines, particularly the contribution of civil society. While civil society’s participation in policy and governance in developing countries is significantly researched, the literature is scant about their involvement in trafficking in persons. This point is relevant to the Philippines for two reasons; (1) it is located in the region with the highest number of global trafficking victims, and (2) it is described to have one of the most vibrant civil societies in the world. This research is engaged with the literature on human trafficking, civil society, and Foucault’s ideas of power and discourse. As such, it examines the ways in which civil society act and organize their efforts in relation to institutional stakeholders, like government organizations and donor agencies. This research utilizes a qualitative approach to illustrate the participation of civil society in protection efforts, particularly in the conflict-ridden southern region of Mindanao. A thematic analysis of plans and reports submitted by the Philippine government to different conventions of the United Nations underscoring human trafficking, as well as alternative reports submitted by non-government stakeholders, is utilized to demonstrate how civil society’s efforts are framed by government stakeholders and how they are negotiated. In-depth interviews with representatives from 11 organizations supplement the analysis. Results generally reveal a heavy reliance by institutional stakeholders on the services of civil society groups for both its prosecutorial and protection obligations, despite civil society’s often adversarial relations with state organizations, shifting relationship with donors, and ideological differences between and among civil society groups themselves. My findings indicate that, beyond mere altruism, these
social processes are significantly impacted by civil society’s political interests and its embeddedness to global migration policy and aid.

Masters thesis, Memorial University of Newfoundland.

abstract:
Newfoundland and Labrador (NL) has the highest rate of obesity in Canada, prompting the
establishment of a bariatric surgery program at the Health Sciences Centre in St. John’s, NL.
This retrospective study examined less than 30-day complication rates in over 200 consecutive
patients between May 2011 and February 2014 who underwent laparoscopic sleeve gastrectomy
(LSG).
A chart review was performed and data collected on less than 30-day post-operative
complications. Complications were graded and reported using the Clavien-Dindo Classification.
Grades I and II were defined as minor and grades III and higher were defined as major.
The first 209 LSG patients were reviewed. The mean BMI was 49.2 kg/m2, 81% were
female and the average age was 43 years. Comorbidities included: hypertension (55.0%),
obstructive sleep apnea (46.4%), dyslipidemia (42.1%), diabetes (37.3%), osteoarthritis (36.4%),
cardiovascular disease with previous cardiac stents (5.3%). Furthermore, 38.3% of patients
reported psychiatric diagnoses such as depression and anxiety. The overall 30-day complication
rate was 15.3%. The complication rate for minor complications was 13.4% and for major
complications was 1.9% (i.e., two leaks, one stricture and one fistula).
Our results support the feasibility of safely performing LSG surgery at bariatric centers
performing fewer than 125 procedures annually.

title: North of Vinland

abstract:
What happens when the romantic and imperialistic stories of Canada’s north become clearly outmoded and unsustainable? In North of Vinland, my collection of linked short stories and essays, I explore the transition from an older narrative mode to a newer, hybrid mode responsive to the demands of the 21st century.
In the short stories, I chart the difficult progress of a floundering grad student in Labrador. While living in Happy Valley-Goose Bay, he must learn to navigate his new home, find a stoic response to his acute depression, reclaim his troubled masculinity, and repair his relationship with his fiancé, Claire. As in any quest, help arrives in the form of a guide: Virgie McLean, a former trapper who remembers the old ways of “them days” and who quietly shapes the narrator’s understanding of the Big Land.
In the essays, which are interwoven with the stories, I discuss Labrador’s explorers (such as Leonidas Hubbard, Mina Benson Hubbard, and William Cabot, among others). In examining the lives and legacies of these explorers, echoes emerge between the experiences of my narrator and the explorers who preceded him. Some, like William Cabot, suggest opportunities and possibilities; others, like Dillon Wallace, should be read as cautionary examples and problematic figures from an imperialistic history.
In the contrapuntal relationship between the stories and the essays, a question emerges: are the elements found in narratives of exploration and frontiers (such as The Lure of the Labrador Wild) inescapable archetypes or can they be re-imagined, subverted, and re-written?
North of Vinland attempts to answer this question by deploying a hybrid, multi-genre narrative that is ironic and self-aware.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract:
This dissertation examines the diasporic experiences of twenty-six professional Chinese musicians who play traditional Chinese instruments. They navigate across music scenes in Canada and the United States by employing intercultural musicianship, the special musicianship they began to develop when learning modernized Chinese music and continue to expand through diverse intercultural musical encounters in multicultural North America. China’s national modernization movements in the late 19th and 20th centuries resulted in significant reforms to music education, particularly the embrace of Western musical instruments, theory, and compositional techniques. These reforms also had profound impacts on Chinese traditional music—from instruments and performance practice to notation and repertoire. Most Chinese musicians in this study were educated in China between the 1960s and the early 2000s. I argue that, despite their individual differences, these musicians’ music-making has been heavily influenced by China’s modernization.
Chinese music students who learn traditional instruments involuntarily embark on an intercultural journey through their Westernized music education. The result is that diasporic Chinese musicians in this study strategically manage the distinct features of their instruments and flexibly utilize their fusion musical knowledge to adapt to multicultural contexts in which both ethnicity and nation are highlighted. In addition to dealing with issues such as perceptions of authenticity and cultural appropriation, they must also manage cultural stereotypes and the expectations of North American music markets. In the process from deterritorialization to reterritorialization, these musicians develop heterogenous subjectivities and interpretations of their cultural identities, especially the concept of “Chineseness” that automatically marks their public personas in Western society. Through personal networks, participation in music
organizations, and access to public funding and sponsorship, they have built individual musical pathways through convoluted transnational routes.
I trace these pathways in several locations: a university centre for Chinese music in Tennessee (until recently funded by the Confucius Institute), the vibrant urban Chinese and intercultural music scenes in Vancouver, a Chinese music education conference in New York City, and the small city of St. John’s, Newfoundland and Labrador, where I study and work as a professional musician. To better understand the complexities of my diasporic consciousness, I also include autoethnographic and practice-based research to trace my own pathway as a Chinese zheng player in North America.

Masters thesis, Memorial University of Newfoundland.

abstract:
Boreal zones contain globally significant organic matter (OM) reservoirs and are currently in a state of rapid change due to shifting temperatures and regional hydrology. Such ongoing change has the ability to alter the export of substantial amounts of OM from these C-rich systems to the coastal environment, which may have major consequences on coastal food web dynamics. In this thesis, I investigate the distribution, dynamics, and salt-induced flocculation of OM across two small adjacent boreal rivers and their immediate coastal zones over three consecutive seasons. Overall, biogeochemical diversity and variation in flocculation potential at local and weekly time scales emphasize the relevance and important inclusion of these underrepresented small coastal systems within regional and global elemental budgets, which will increase the efficacy of future biogeochemical flux predictions from the land to sea. In the second chapter of my thesis, observations of the distribution and dynamics of particulate and dissolved (D)OM highlight important linkages between OM dynamics and local and seasonal physico-chemical, biological, and hydrological processes that were potentially enhanced at a weekly scale during the summer-to-fall transition period. The findings of this observational study also revealed that over 95% of the freshwater organic carbon is in the dissolved fraction with characteristics of being terrestrially derived, aromatic, and C-rich. These characteristics, along with dissolved iron, were also selectively removed by salt-induced flocculation processes, as highlighted in the third chapter of my thesis. Overall, results from the experimental study emphasize the relevant contribution of flocculation as a process affecting the removal of OM from pelagic zones to the benthos, which can occur across a broad range of salinities (1-25 psu). The findings in my thesis also encourage the use of dissolved iron measurements and calculations for dissolved iron to dissolved organic carbon ratios in future biogeochemical studies as they were found to be especially informative for assessing the temporal stability of DOM as well as degree of flocculation across adjacent systems with differing catchment types. Changing environmental conditions will result in greater day-to-day variability in river hydrology and subsequently affect the fluxes, cycling, and fate of OM, and to better predict and understand the consequences of
these changes, an increased representation of small near-shore coastal systems with recognition of its biogeochemical diversity in regional and global elemental budgets is required.

abstract: This thesis examines American diplomats, policymakers and officials who criticized US policy choices in Guatemala during the 1960-1996 Guatemalan Civil War. Using recently declassified American government documents, this thesis makes four primary arguments. First, it analyzes the volume, spread, and nature of voices of dissent within the US government and illustrates that dissenting opinions were more numerous and widespread in the second half of the conflict. Dissent was largely based on moral grounds, but other categories of dissent emerged as the US pursued human rights policies. Second, this thesis explores whether Jimmy Carter’s human rights-based foreign policy impacted the nature of governmental dissent during the remainder of the Civil War. It argues that while Carter’s policies led to an immediate explosion of dissent, there was very little short-term impact on policy changes. In the long term, however, the language of human rights served as a powerful tool of dissent and criticism, and Carter’s legitimization of human rights policy laid the groundwork for future dissenters to achieve meaningful policy changes at the end of the Civil War. Third, it considers whether the creation of a formal Dissent Channel meaningfully impacted US officials concerned with American actions in Guatemala and concludes that the Dissent Channel had minimal impact on officials who disagreed with policy choices. Instead, officials overwhelmingly opted to dissent through informal procedures that clearly identified themselves rather than hiding behind the Dissent Channel’s anonymity. Finally, it analyzes whether dissenters (both those who did and did not use the Dissent Channel) meaningfully impacted US policy choices. It argues that despite the overall lack of interest in using the Dissent Channel, dissenters still meaningfully impacted US foreign policy choices in Guatemala. In particular, dissenting opinions helped legitimize human rights as a viable policy choice and served as a check on the US government’s activities in Guatemala. This thesis makes a worthwhile contribution to both scholarship on US policy in Guatemala and the emerging field of dissent literature, as it allows for more nuanced analysis of US Cold War foreign policymaking.

abstract:
Livestock manure and organic agriculture wastes are an environmental challenge because they contribute to climate change by emitting greenhouse gases. Converting these organic wastes to biogas and bioenergy is a sustainable solution. Farmers, investors, and governmental departments involved in developing on-farm biogas projects need an informed decision-making process to fund such projects. Therefore, estimating the costs of biogas plant components and the required initial investment for a farm-based biogas plant is essential. This study develops two methods to estimate the cost of farm-based biogas projects, determine their economic viability, predict the cost of each part of the plant, and analyze its related risks. The models base on available cost data of current on-farm biogas plants for dairy farms in Canada. First, by using regression analysis, cost predicting models are developed and used to indicate the costs related to biogas plant construction based on the number of cows (CN) housed in a farm. Furthermore, risk analysis is applied to investigate the most probable outcome of the cost models and the dataset with the help of Monte Carlo simulation. In general, the dataset included two groups of farms (less than or greater than 1000 cows). The capital cost is predicted mathematically based on the number of cows (CN) and hydraulic retention time (HRT). In addition, the study developed detailed models for major components of a biogas plant (anaerobic digester, pumping unit, upgrading unit, CHP unit). The result of the Monte Carlo simulation shows that the average cost for on-farm- biogas plants based on the currently available dataset would be about $4.3 million, with an average of 960 cows per farm. Finally, the results of this study have been applied on an actual farm (Lester’s Dairy Farm)
located in St. John’s, Newfoundland, as a case study. Almost $2.5 million investment is required to develop such a biogas plant on this farm, considering a herd of 550 cows housed in the farm.

abstract:
This thesis examines the representation of virtual reality and nuclear apocalypse in three
cyberpunk texts – Neuromancer by William Gibson, Snow Crash by Neal Stephenson, and Tea
from an Empty Cup by Pat Cadigan – and finds that each novel uses virtual and nuclear imagery
to explore signification. Each text’s vision of virtual reality is informed by either a Platonic or
Baudrillardian theory. Neuromancer and Snow Crash both suggest that the virtual world is the
world of Forms because its signs (graphics and code) are wholly commensurate with their
referents (aspects of the virtual world itself). Tea from an Empty Cup, however, suggests that the
virtual world consists of empty signs whose original referents (an absent framing world and an
untold nuclear history) are missing and beyond recovery, because nothing exists outside of the
simulation. Each novel’s depiction of virtual reality as a space of either ideal truth or endless
simulation correlates (through accordance or opposition) with its conception of nuclear
apocalypse. Neuromancer follows Derrida in suggesting that the a-symbolic nuclear referent is
the only possible true referent, as the apocalypse represents a simultaneous moment of truth
revealed and reference lost. In contrast, both Snow Crash and Tea align with Baudrillard’s
reading of the nuclear as the height of simulation, and the attendant implication that simulation is
always already post-apocalyptic. Whether the nuclear event is figured as a moment of revelation
or pure simulation, each text points to the impossibility of imagining (even science fictionally) a
post-nuclear future, and thus, each reflects on its own end (in both senses of the word) as a
representational work. Accordingly, I read cyberpunk as a metafictional reflection on the life and
death of a novel.

As a state party of the United Nations Convention of the Rights of a Child and the first country to ratify it in 1990, the Government of Ghana indicated its willingness to protect youth's rights. In accordance with signing the treaty, the government established the Juvenile Justice Act (JJA) 2003 (Act 653) to locally implement the treaty's core imperatives. Despite the enthusiasm shown by the government, the few studies that exist in this neglected area suggest a gap between the spirit and the letter of the law. However, these studies have solely relied on anecdotal data, skewing the focus on the Juvenile Justice Act’s compliance to the international treaties. Contributing to the scant body of literature, in the current study, I explore the juvenile court's procedures in age determination and jurisdiction, bail and remand, duration of cases and sentencing procedures, and adherence to the policy of the JJA.
I employed qualitative content analysis to data collected from 290 summarized court case dockets from the archival unit of the Ghana High Courts. The findings showed that the Ghanaian juvenile courts put in efforts to adhere to the guidelines in the JJA. However, the shortage of trained professionals, along with the system's lack of resources and logistics, impede the efforts of the juvenile courts. Based on the findings of this research, I recommend that the government ensure youth custodial facilities/institutions are responsible, in legislation and in practice, for the care and well-being of young people living there, by first allocating more resources and funding to the juvenile unit of the police and to the Department of Social Welfare, and by providing specialized training to people working in the youth justice system in Ghana.

abstract:
Youth involved in the street (YIS) suffer from higher rates of attachment insecurity, childhood
maltreatment, and psychopathology than their non-street involved peers, yet little is known
about how boy and girl YIS differ in their expression of attachment. The aim of this study was to
explore the relationship between gender, attachment orientation, childhood maltreatment, and
psychopathology in a sample of YIS to generate hypotheses for future research and inform
targeted therapeutic interventions in this underserved population. The study combined data
from two previously collected samples of youth (108 total: 41 girls, 67 boys), aged 15 to 24,
recruited from a community non-profit organization in St. John's, Newfoundland and Labrador,
Canada, who were administered validated self-report measures of attachment orientation,
childhood maltreatment, and psychopathology. Statistical analyses included one-way
multivariate analyses of variance (MANOVA), independent samples t tests, and multiple
regressions using a running-interval smooth. The analysis revealed that girl YIS report
significantly higher rates of attachment anxiety and childhood maltreatment, but comparable
rates of attachment avoidance and psychopathology relative to boy YIS. Rates of attachment
anxiety strongly predict rates of attachment avoidance in girl but not boy YIS; further, this is
expressed in a strongly curvilinear fashion. Implications of these findings are discussed relative
to gender-based theories of attachment and the provision of targeted mental health
interventions in YIS.

title: Schelling's political philosophy

abstract:
In his commitment to the preservation of human freedom, Schelling repeatedly defends the existence of a minimal state, which he claims is necessary for freedom’s realization. But the state is not the apex of Schelling’s political philosophy. Schelling instead proposes that through the exercise of freedom, human beings can forge meaningful human relationships, which have the potential to form a ‘voluntary,’ or consensual, free community beyond the state. His political philosophy, therefore, concerns first and foremost the possibility of the free establishment of a just human community, which transcends the state.
Schelling does not give a clear, coherent account of the final form of a free, voluntary community before 1831. However, he sporadically writes about the political throughout his entire career, from his earliest works of the 1790s onwards. In this dissertation, I reconstruct Schelling’s entire political philosophy. I argue that his commitment to individual freedom and, in 1809 and after, personhood and love, structures his moral philosophy in such a way that it necessitates his repeated postulation of a minimal state. However, this state is insufficient on its own to bring about a moral community. Schelling’s reflections on the state and the community are always couched in a shifting historical and political context, which I describe throughout.
Schelling’s political trajectory is non-linear. I thus open this work by describing the exception to Schelling’s otherwise consistent separation of the minimal state from the voluntary, human community. This exception is the organic state as postulated in Schelling’s early Identity Philosophy (1801-1804). I argue that Schelling’s growing concern for the individual from 1804-1807 leads him to progressively move away from this organic state, in which freedom and necessity, community and the state, are unified. Instead, the community becomes the free endeavour of dynamic, developing individuals on the road to personhood.
Before moving on to Schelling’s middle thought in Chapter 4, I backtrack to his earliest writings to unearth the roots of his post-1809 political philosophy. Accordingly, in Chapter 2, I give an account of Schelling’s first clear presentation of the state as the guarantor of freedom in his 1800 System of Transcendental Idealism. I situate this presentation of the state in the context of Schelling’s early philosophy of nature and freedom and show its role in the System’s philosophies of history and politics. Chapter 3 takes us even further back to an excavation of the romantic roots of Schelling’s political philosophy in his very young writings, from 1792-1797.
ix
Here, I show that Schelling’s experimental attempts to ascertain the relationship of the law—including state law—to a higher, free unity, particularly through aesthetics, were influenced by Rousseau, Kant, Schiller, especially during his time at the Tübinger Stift.
I subsequently demonstrate how some of these early romantic insights come to fruition in Schelling’s moral and political philosophy in his work after 1809. Schelling’s accounts of personhood, love, and the development of virtues create the possibility of the establishment of a free, moral community beyond the state. This endeavour requires a division between the state as a legal order and the community, which consists of free relations, otherwise described by Schelling in the terminology of love. Once Schelling settles on this insight, he begins not only to critique the state (most famously and harshly in 1810), but also to describe it as a rational order which is an expression of a divine idea. This differs from his earlier presentations of the state as mechanical (1800) and organic (1801-1804). I show that this concept of the rational state is best comprehended when related to the promise of redemption and the reestablishment of the lost unity between humanity and God. This loss presents a gap which the state itself can never close.
My fifth and final chapter offers a detailed presentation of Schelling’s final form of the human community, which he calls the “Church of St. John.” This is a community of the future, into which all will enter freely and in which knowledge and revelation are united. It is characterized by the total unity of the human community and the creative practice of a non-denominational, “philosophical religion”—a religion which does not yet exist. I conclude the dissertation with a summary of the role of necessity in Schelling’s different forms of the state (now understood as the ground of the free community) and in personality. I also offer a brief account of how we might read Schelling’s political philosophy today. Schelling’s political pessimism, I suggest, finds an affinity with the critical theory tradition, as his political philosophy involves a radical critique of the status quo and the possibility of a transformation of existing socio-political relations that relies on a notion of the transcendent.

format: application/pdf application/pdf

abstract: In this study, I situate the work of Gender and Sexuality Alliance (GSA) advisors within the context of the Safe and Caring Schools Policy (SCSP) in Newfoundland and Labrador (NL) and explore the ways in which GSA advisors leverage social capital in support of 2SLGBTQIA+ students in the province. Using a qualitative study design, I first reviewed the progression of the SCSP and its relationship with 2SLGBTQIA+ programming in NL public schools. I then explored GSA advisors’ experiences in GSA by conducting semi-structured interviews with nine GSA advisors, employing egocentric network analysis to examine how they leveraged social capital within their social networks in support of their GSA work. I found that GSA advisors leverage social capital in a variety of ways with certain conditions influencing and facilitating this process: 1) the diversity of GSA advisors’ networks matter for the GSA work and this composition facilitates bridging social capital, 2) trusting relationships are very important for GSA advisors’ roles as they support bonding social capital; 3) school administrators and Safe and Caring Schools itinerants—policy actors who support the implementation of the policy—are key individuals for the GSA work as they facilitate GSA advisors’ access to important resources, thereby supporting bonding and bridging social capital respectively; and 4) policy shapes behavior when and where the policy is understood. I conclude by arguing the importance of social capital and network theories in understanding the inequitable access to social capital by minoritized populations.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract:
Greater collaboration with Inuit in community-based sea ice research has led to changes
in research approaches used by non-Indigenous researchers. However, there remains a gap in the
collaborative sea ice literature describing how non-Indigenous researchers are decolonizing
themselves and their research. This thesis explores a personal and collective research journey
with Sikumiut (people of the sea ice), an Inuit research management committee from
Mittimatalik (Pond Inlet), Nunavut, in order to fill this gap and to support the greater goal of
Inuit self-determination in research It describes: 1) my decolonizing methodology; 2) the
process of co-developing the Sikumiut model, a cross-cultural decolonizing research approach to
advance Inuit self-determination in research; and 3) transitioning from theory into practice to
meet Sikumiut’s research needs.
Variable sea ice conditions, a reduced travel season, and pressure to expand shipping are
climate change impacts compounding the dangers of sea ice travel in Mittimatalik. Sikumiut
wanted to document their Inuit Qaujimajatuqangit (IQ, Inuit knowledge) to share critical sea ice
travel knowledge and skills with youth, and to understand where and when the sea ice is
changing. The Sikumiut model reconceptualized typical research approaches, with Sikumiut
governing the research, and non-Indigenous research partners training and mentoring Inuit youth
to conduct the research. The multiple benefits of Inuit leading and conducting this research, to
capture and mobilize their own sea ice IQ are described through the co-production of: 1)
Sikumiut’s illustrated sea ice terminology book, three seasonal sea ice travel maps and two
safety posters for community use; and 2) the Mittimatalik siku asijjipallianinga (sea ice change
atlas), which involved the Inuit interpretation of satellite imagery and sea ice charts from 1997 to
2019 based on sea ice travel IQ. The Sikumiut products show the continued relevance of IQ as
an adaptation tool for safe sea ice travel. The atlas also provides evidence that shipping during
critical periods of sea ice formation and break-up would compromise the integrity and duration
of the sea ice travel season for the community.

abstract:
The referendum of 2016 took Brexit to the centre stage as one of the controversial discourses in the United Kingdom. Particularly, the role of the media in framing immigration during Brexit campaign makes it worthy of attention. Using the framing theory, the study gave a descriptive analysis of how the media framed immigration in the context of Brexit campaign. Relying on primary data, the study selected 104 distinct articles published by selected UK national newspapers from the LexisNexis database, and analyzed them under seven frames identified: social welfare, labour market, national identity, law and order, Turkey’s possible EU membership, terrorism, and moral values. It combined both quantitative and content analysis to give robust results.
Findings show that while newspapers claim to be neutral entities, they were largely involved in crafting their stories to favour either pro-Leave or pro-Remain group. The study concludes that unless the news media maintain their objectivity within the theatre of politics, they will continue to remain like the two sides of a coin that can unite different and diverse forces together or cause them to fall apart.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract:
Background: Complex patients have multiple, ongoing health conditions, often with limited resources, and are frequent recipients of health and social care services. Complex patients experience discrimination and are often shown a lack of compassion from nurses and other health professionals which negatively impact their care experiences and health outcomes. Missing in the practice literature are the strategies to guide much needed improvements in the compassionate nursing care of complex patients.
Purpose: The purpose of this doctoral dissertation was to enhance understanding of the indicators of, and barriers to, compassionate nursing care delivery and to propose implementation strategies with potential to promote compassionate nursing care of complex patients.
Methods: An exploratory sequential mixed methods design was conducted comprised of a qualitative phase, an instrument development phase, and a quantitative phase. The qualitative phase enabled identification of indicators and barriers based on interviews with 23 individuals with experiences as complex patients. Barriers were then mapped to implementation science frameworks in the instrument (i.e., a Q-sort survey) development phase to identify relevant domains and integration functions, and to choose implementation strategies for the survey concourse. The Q-sort survey was then electronically distributed during the quantitative phase to over 140 nursing, health, and compassion care experts, out of which 32 responded and ranked the strategies. Principal component analysis determined highest ranked strategies. A five-factor solution was generated using Varimax rotation. Merging technique confirmed the rankings before strategies were subsequently
operationalized using an implementation science specification framework, followed by development of an implementation plan.
Results: Participants identified six indicators of compassionate nursing care—nurses who are: sensitive, aware, positive, nonjudgmental, empathic, and altruistic. Barriers were categorized under knowledge, intentions, skills, social influences, behavioural regulation, reinforcement, emotion, and environmental context and resources. The final operationalized implementation strategies included: organize clinician implementation team meetings, involve patients and families, modelling, implementation facilitation, and ongoing consultation with stress experts.
Conclusions: Implementation strategies made specific for practice contexts are urgently needed to effect change at provider, managerial and organizational levels to improve compassionate care experiences of complex patients. One promising approach are alliances between health professionals and patient and family groups to design, plan, and implement strategies to improve compassionate nursing care.

abstract:
The immunoglobulin (Ig)-based adaptive immune system (AIS) evolved ~ 500 million years ago in jawed vertebrates, while the jawless vertebrates exhibit their own variable lymphocyte receptor (VLR)-based AIS. An evolutionarily conserved hallmark of the Ig-based AIS is the diversification of Ig-class antibodies through somatic hypermutation and/or class switch recombination of Ig genes, initiated by the DNA-mutating enzyme activation-induced cytidine deaminase (AID). The VLR-based AIS may also involve activities of AID-like enzymes, but their specific activities have remained unclear. Each clade of vertebrate fishes possesses genetically diverse AID and AID-like enzymes, whose biochemical characteristics, and in some cases functionality, were not known. To elucidate structure-function relationships and to biochemically characterize these distinct proteins, I examined AID homologs from the sea and freshwater lampreys, nurse shark, zebrafish, tetraodon, coelacanth, and human. First, I discovered that the nurse shark and coelacanth, both species representative of significant evolutionary junctures of vertebrate speciation, posses an active AID enzyme. Second, I found the highly unusual human AID biochemical properties of lethargic activity and high affinity binding to its single-stranded DNA substrate were conserved across all vertebrates, while other characteristics, like optimal temperature and sequence preference, diverged. Interestingly, while most vertebrates have only one AID gene, the freshwater lampreys were found to have multiple AID-like genes, grouped into cytidine deaminase 1 (CDA1), CDA1-like, and CDA2 genes, based on the CDA1 and CDA2 genes found previously in the sea lamprey. Furthermore, each individual expresses different combinations of the AID-like genes. The CDA1 and CDA1-like enzymes exhibited varying pH sensitivities and enzyme activity levels, similar to the differences between human AID and its APOBEC family member enzymes, thus suggesting unique roles for the CDA1 and CDA1-like
enzymes in the lamprey AIS. Faint activity was detected for the sea lamprey CDA2, similar to ongoing, yet unpublished, efforts by other research groups. This is the first study to biochemically and structurally characterize AID and AID/APOBEC-like enzymes covering the span of fish evolution. This multidimensional approach of multi-species in silico structural analysis and in vitro biochemical characterization exemplifies a comprehensive method for gaining deep insight into enzyme activity, function, and evolution.

abstract:
This narrative inquiry explores Canadian journalists’ perspectives and experiences around uncensored User-Generated Content (UGC) and trauma reporting from the digital frontline. Rich experiential data were generated through a series of one-on-one virtual interviews with four Canadian journalists. These discussions focused on topics from everyday emotionally
demanding assignments involving uncensored UGC to trauma informed education, training, and
practice in the field. The main themes identified were journalistic capital, the ubiquitous nature of trauma in daily news coverage, the structure of work, uncensored UGC, and lack of formal education, training, and supports. This thesis argues that UGC is changing how journalists source news material and interact with the public. With this shift comes new psychosocial hazards that must be addressed by journalism educators, newsroom managers, and occupational health and
safety scholars and professionals. Bourdieusian thought was applied to the occupational health
and safety of journalism and fills a knowledge gap in the occupational health literature as psychological injury is often studied in war correspondents and less so in relation to journalists exposed to psychosocial hazards while in pursuit of journalistic capital on the digital frontline.

abstract: This study builds on the upper echelons theory to investigate the effect of CEO Machiavellianism on firm performance. I hypothesize a negative relationship between CEO Machiavellianism and firm performance. Furthermore, I hypothesize that managerial discretion will moderate this relationship such that the negative effect of CEO Machiavellianism on firm performance will be more substantial when managerial discretion is high. I found support for these hypotheses using a sample of 97 CEOs from Standard and Poor's 500 companies and utilizing a video-based measurement technique for CEO Machiavellianism. Finally, I discuss the implications and limitations of the study.

abstract: Ce mémoire fait ressortir les thèmes et les faits démontrant que la femme au sein de la société décrite dans l’oeuvre La muette de l’écrivaine franco-iranienne, Chahdortt Djavann, est marginali-sée. Elle subit la violence à la fois physique et psychologique. Non seulement elle est marginalisée et reléguée au second plan dans la société, mais elle est aussi privée de ses droits les plus fonda-mentaux comme le droit à l’éducation, le droit à la liberté d’expression, le droit au style vestimen-taire, etc. Cette marginalisation ne concerne pas que la femme adulte mais aussi, et plus encore, la jeune fille. En effet, en plus de subir les mêmes difficultés, les jeunes filles sont victimes de ma-riages forcés, de violences et d’abus sexuels, de grossesses non désirées, et ce malgré leur jeune âge. Les causes de cette marginalisation et son impact sont également analysés au travers des per-sonnages de l’oeuvre.
