abstract: This thesis examines the gaps between health care services aimed at Aboriginal queer individuals living in St. John’s, Newfoundland and their health care needs. I used a multi-methods research design that includes interviews and demographic surveys, unobtrusive observation and qualitative content analysis. I conducted semi-structured interviews with institutional representatives from selected health related organizations – Eastern Health, Planned Parenthood Newfoundland and Labrador, the AIDS Committee of Newfoundland and Labrador, and St. John’s Native Friendship Center; as well as a transgender activist and three people who identify as Aboriginal and queer. I conducted observational research at two public seminars on Aboriginal people and health. Finally, I carried out qualitative content analysis of organizational reports and webpages of the selected community organizations. Using a postcolonial queer framework that analyzes how Newfoundland and Labrador’s colonial history is reflected in current health care realities I argue that the lack of appropriate services and culturally insensitive delivery of services reproduce the historical marginalization of an already vulnerable group.

type: Thesis NonPeerReviewed

abstract:
The Pope’s Hill (PH) rare earth element (REE) occurrence, located in central Labrador, is a syenite-hosted, highly enriched unit with whole-rock geochemical analyses indicating REE contents ranging from <1 to 22 weight percent. Samples of ore, altered host rock, and unaltered country rock, were collected throughout the occurrence in order to: 1) determine which phases concentrate the REE and also quantify their abundances and distribution in the ore; 2) determine the host rock emplacement age; 3) determine the timing of the subsequent hydrothermal alteration and REE mineralization; and 4) constrain the source of the REE using in situ LA-ICPMS and ID-TIMS U-Pb geochronology and in situ Sm-Nd isotopes using LA-MC-ICPMS in monazite.
The REE-enrichment occurs in millimeter- to decimeter-scale pods that are locally discontinuous and consist of primary and secondary REE minerals including a variety of silicate, phosphate, carbonate, and niobate phases; the most abundant being allanite-(Ce), monazite-(Ce), britholite-(Ce), and an unnamed LREE-enriched mineral similar in composition to titanite.
ID-TIMS geochronology reveals monazite dates from ~1090 to 940 Ma that coincide with Grenvillian metamorphism and plutonism during continent-continent collision suggesting that locally derived REE in the PH syenite crystalized into primary REE-silicates either before or during Grenvillian events. Microtextures in thin section indicate that secondary non-silicate REE minerals were produced by the breakdown of primary REE-silicates, suggesting either hydrothermal fluid alteration, or metamorphism.

abstract: The growing popularity of dog parks has created an opportunity to learn more about interactions between companion dogs. Dog-dog behaviour in a public off-leash dog park was described and analyzed using a motivationally-neutral approach. I observed focal dogs from park entry for 400 s and constructed activity time budgets (percentages of time spent with dogs, humans, etc.); rates of socially-relevant dog behaviours (e.g., snout-muzzle contact, physical contact) were also calculated. On average, focal dogs spent 50% of their time alone, nearly 40% with other dogs and 11% in other activities; time with dogs decreased and time alone increased over the first six minutes. Some behaviours were very frequent (i.e., more than 90% of focal dogs initiated and received snout-muzzle contact to the anogenital and head areas, while others were rare (i.e., 9% and 12% of focal dogs initiated and received lunge approaches, respectively). Dog density and focal dog age, sex, neuter status, and size were found to influence some behavioural variables. Future studies should continue to investigate the diverse range of canid behaviours and factors that influence social behaviours in dog park settings.

abstract:
Patient satisfaction with health care is an important indicator of quality services and has
been related to positive health outcomes. Because little is known about whether
adolescents with physical disabilities are satisfied with the services they receive, the
current study investigated the extent to which adolescents are satisfied with health care
services, aspects of care adolescents identify as important to their satisfaction, similarities
between adolescent and parent perceptions of care, and the relationship between
adolescent perceptions of care and their intentions to adhere to treatment
recommendations. Following recruitment from a pediatric health center, adolescents and
their parents (n = 42) completed questionnaires to assess their perceptions regarding
various aspects of health care services. Participants were very satisfied with services
received; interpersonal aspects of care were very important to them. Adolescents’
satisfaction was not predictive of their intentions to adhere to treatment recommendations
and their perspectives differed from those of their parents.

abstract:
There have been a few reports that snow generates sound similar to that of
rain when it strikes the ocean surface but it is hard to imagine that the
mechanisms responsible for rain sounds could be the same as those that
cause sound from falling snow. We explore the sound generated by falling
snow through laboratory measurements under different atmospheric
conditions that give rise to variety of snowflake types with different snowfall
rates by using a small tank filled with tap water. We find that there is a well
defined spectral peak at around 12 kHz (similar to that of rain) in sound
generated by some snow types; other snow types do not produce appreciable
underwater sound. The data suggest that the sound generated by falling snow
is such that ocean snowfall rates could be estimated by evaluating spectral
characteristics of the sound. More experiments need to be done for that
purpose as sound levels depend on snowfall rate, snow types, sea state, and
wind speed.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract:
The foreword to the report on the Surgeon General's Conference on
Children's Mental Health highlights the crisis-that has been ~reated by the
suffering experienced by children with mental health problems and their families
(U. S. Public Health Service, 2000). The importance of valuing the families of
these youth, building on their strengths, and having available an array of social
supports has been widely recognized. Despite this endorsement, little
theoretical development or empirical validation has been done that supports the
development and strengthening of parental social support in social work
interventions.
The purpose of this dissertation is to contribute to a conceptual and
empirical understanding of the pathways between social support, family well
being, quality of parenting, and the development of child resilience in families
with a child with serious emotional problems. Based on a review of key concepts
and empirical findings within these constructs, a conceptual model and a set of
research questions are proposed to describe the transactional relationships
between the four domains. The method includes three primary analytic activities
(conceptual mapping, scale development, and structural equation modeling) to
investigate the validity of the model and the associations between the dependent
and independent variables.
The findings are that parental social support is significantly and positively
correlated with family well being and with quality of parenting. Family well being and quality of parenting are positively associated with child resilience. The
model explains 3% to 5% of the variance in child resilience; and family well being
is the strongest predictor of child resilience. $ocial support accounts for 6% of
the variance in family well being, and social support and family well being
account for 54% of the variance in quality of parenting.
The study findings empirically validate the protective role of social support
in families with a child with serious mental health problems. Social work practice
needs to recognize the importance of social support in the practice acts of
assessment and intervention. Social work research needs to develop new
methods and new measures for understanding the complex relationships among
social support, family well being, quality of parenting, and child resilience.

abstract: This thesis examines the connections between hagiography and history in the Historia ecclesiastica gentis anglorum ("The ecclesiastical history of the English people") by the Venerable Bede (died 735). The discussion of Anglo-Saxon saints focuses on the hagiographical and political reasons for including miracle stories in this text and how the traditional cults of these native saints represent the English Church within the larger framework of medieval Christianity. In particular the discussion has a Northumbrian focus and looks at King Edwin, St. Oswald, and the popular English saints Cuthbert and Æthelthryth, with specific reference to the political and spiritual contributions these figures made to the conversion of Anglo-Saxon England and to the moral and spiritual reform that is central to the internal message of Bede's Ecclesiastical history.

abstract: In survival studies the individual study subjects may experience multiple failures. These failures may be repetitions of the same kind of event or may be events of different natures. Most of the multivariate incomplete failure time problems discussed so far in the literature are of the former type. The multivariate incomplete failure time problem of the second type has not been adequately addressed in the literature. In this practicum, we concentrate on the multivariate incomplete failure time problem of the first kind. Many authors, for example, Wei, Lin, and Weissfeld (1989, JASA) have analysed this type of multivariate incomplete failure time problem by using the univariate partial likelihood approach. The application of the univariate partial likelihood approach to such correlated failure time data may not, however, reveal the actual effect of the treatment. To overcome this problem, we propose an ad hoc modification to this type of multivariate incomplete failure time data, in order to make the failure times (recorded at different stages) independent, and then apply the univariate partial likelihood approach to obtain (estimate) the treatment effects. Further, under the assumption that the treatment effect remains the same all throughout the study group (failure group), we estimate the combined treatment effects for multivariate incomplete failure time data, by using the restricted partial likelihood estimation (RPLE) method. The univariate partial likelihood method applied to the modified data appears to provide more appealing inferences about the treatment effects than when this method is applied to the original data. Also the restricted partial likelihood estimation (RPLE) method appears to provide more precise estimates for the combined treatment effects as compared to the linear estimation (LE) method used in the literature, for example, by Wei et al. (1989).

abstract:
This thesis involves two parts. The first is a new-proposed theoretical approach
called generalized atoms in molecules (GAIM). The second is a computational study
on the deamination reaction of adenine with OH⁻/nH₂O (n=0, 1, 2, 3) and 3H₂O.
The GAIM approach aims to solve the energy of each atom variationally in the first
step and then to build the energy of a molecule from each atom. Thus the energy of
a diatomic molecule (A-B) is formulated as a sum of its atomic energies, EA and EB.
Each of these atomic energies is expressed as,

EA = Hᴬ + Vₑₑᴬᴬ + 1/2Vₑₑᴬ<>ᴮ

EB = Hᴮ + Vₑₑᴮᴮ + 1/2Vₑₑᴬ<>ᴮ

where; Hᴬ and Hᴮ are the kinetic and nuclear attraction energy of electrons of atoms
A and B, respectively; Vₑₑᴬᴬ
 and Vₑₑᴮᴮ
 are the interaction energy between the electrons
on atoms A and B, respectively; and Vₑₑᴬ<>ᴮ is the interaction energy between the
electrons of atom A with the electrons of atom B. The energy of the molecule is then
minimized subject to the following constraint,

|ρA(r)dr + |ρB(r)dr = N

where ρA(r) and ρB(r) are the electron densities of atoms A and B, respectively, and
N is the number of electrons. The initial testing of the performance of GAIM was done through calculating dissociation curves for H₂, LiH, Li₂, BH, HF, HCl, N₂, F₂, and Cl₂.
The numerical results show that GAIM performs very well with H₂, LiH, Li₂, BH, HF,
and HCl. GAIM shows convergence problems with N₂, F₂, and Cl₂ due to difficulties
in reordering the degenerate atomic orbitals Pₓ, Py, and Pz in N, F, and Cl atoms.
Further work for the development of GAIM is required.
Deamination of adenine results in one of several forms of premutagenic lesions
occurring in DNA. In this thesis, mechanisms for the deamination reaction of adenine
with OH⁻/nH₂O, (n = 0, 1, 2, 3) and 3H₂O were investigated. HF/6-31G(d),
B3LYP/6-31G(d), MP2/6-31G(d), and B3LYP/6-31+G(d) levels of theory were employed
to optimize all the geometries. Energies were calculated at the G3MP2B3 and
CBS-QB3 levels of theory. The effect of solvent (water) was computed using the polarizable
continuum model (PCM). Intrinsic reaction coordinate (IRC) calculations were
performed for all transition states. Five pathways were investigated for the deamination
reaction of adenine with OH⁻/nH₂O and 3H₂O. The first four pathways (A-D)
begin with by deprotonation at the amino group of adenine by OH⁻, while pathway
E is initiated by tautomerization of adenine. For all pathways, the next two steps
involve the formation of a tetrahedral intermediate followed by dissociation to yield
products via a 1,3-hydrogen shift. Deamination with a single OH⁻ has a high activation
barrier (190 kJ mol⁻¹ using G3MP2B3 level) for the rate-determining step. Addition
of one water molecule reduces this barrier by 68 kJ mol⁻¹ calculated at G3MP2B3
level. Adding more water molecules decreases the overall activation energy of the reaction,
but the effect becomes smaller with each additional water molecule. The most
plausible mechanism is pathway E, the deamination reaction of adenine with 3H₂O,
which has an overall G3MP2B3 activation energy of 139 and 137 kJ mol⁻¹ in the gas
phase and PCM, respectively. This barrier is lower than that for the deamination with
OH⁻/3H₂O by 6 and 2 kJ mol⁻¹ in the gas phase and PCM, respectively.

title: Safety in bear country

abstract:
Safety in Bear Country tells the story of Serena Palmer’s twenty-second year. At
a time when she thought she would be making a living in Toronto as an artist and as an
independent adult, the economic times and her emotionally fragile state due to the demise
of a romantic relationship, prove obstructive. Instead, she lives in the basement of her
parents’ home and works for the town’s largest employer, a mental institution. Here she
embarks on an internal quest for meaning and a truer understanding of love. Specifically,
as the novel’s action shifts through Australia and then to Northern Canada, ending with
her near-death and shamanistic spiritual transcendence, Serena explores the contradictions
that exist between love and fear: in order to ever fully love, one must make oneself
vulnerable at the deepest level. And, in order to ever make oneself vulnerable, one must
conquer fear. In this way, fear and love are inextricably connected. Here in lies the irony
of the title: Safety in Bear Country.

abstract:
Structure, energetics and reactions of ions in the gas phase can be revealed by mass spectrometry techniques coupled to ions activation methods. Ions can gain enough energy for dissociation by absorbing IR light photons introduced by an IR laser to the mass spectrometer. Also collisions with a neutral molecule can increase the internal energy of ions and provide the dissociation threshold energy. Infrared multiple photon dissociation (IRMPD) or sustained off-resonance irradiation collision-induced dissociation (SORI-CID) methods are combined with Fourier Transform Ion Cyclotron Resonance (FT-ICR) mass spectrometers where ions can be held at low pressures for a long time. The outcome of ion activation techniques especially when it is compared to the computational methods results is of great importance since it provides useful information about the structure, thermochemistry and reactivity of ions of interest.
In this work structure, energetics and reactivity of metal cation complexes with dipeptides are investigated. Effect of metal cation size and charge as well as microsolvation on the structure of these complexes has been studied. Structures of bare and hydrated Na and Ca complexes with isomeric dipeptides AlaGly and GlyAla are characterized by means of IRMPD spectroscopy and computational methods. At the second step unimolecular dissociation reactions of singly charged and doubly charged multimetallic complexes of alkaline earth metal cations with GlyGly are examined by CID method. Also structural features of these complexes are revealed by comparing their IRMPD spectra with calculated IR spectra of possible structures. At last the unimolecular dissociation reactions of Mn complexes are studied. IRMPD spectroscopy along with computational methods is also employed for structural elucidation of Mn complexes. In addition the ion-molecule reactions of Mn complexes with CO and water are explored in the low pressures obtained in the ICR cell.

Masters thesis, Memorial University of Newfoundland.

abstract:
Current models of shallow rocky community organization and stability in the
northwestern Atlantic (NWA) emphasize kelps and their vulnerability to grazers and
other mortality agents. This paradigm may overshadow the possible contribution of other
groups of less studied seaweeds with overlapping distribution to ecosystem resilience.
The annual, brown seaweed Desmarestia viridis is one of only a few species of fleshy
seaweeds commonly found in urchin barrens in the NW A. The exceptional ability of
D. viridis sporophytes to produce and store sulfuric acid (H₂S0₄) in intracellular vacuoles
makes the species a compelling model for studies of controls and importance of acid
production in seaweeds at the individual, population, and community levels. This research
used laboratory experiments and surveys of individuals and populations throughout an
entire growth season (February to October 2011) at two subtidal sites on the southeastern
tip of Newfoundland (Canada) to determine controls of acid production in, as well as the
functional importance and persistence of, D. viridis sporophytes. Results showed that
light, grazing, and epibionts have no perceptible effects on intracellular acidity, whereas
temperature and wave action exert strong, synergistic effects. Mortality rates and sea
temperature from March to late June were relatively low, whereas the onset of increasing
mortality in mid-August coincided with marked increases in sea temperature. The quick
development of "Desmarestia beds" in urchin barrens created biological structure for
major recruitment pulses in characteristic invertebrate and fish assemblages. These
findings provide novel insights into the ecological and evolutionary causes and
consequences of acid production in Desmarestiales, while elevating the importance of
D. viridis as a foundation species in urchin barrens in the NWA.

abstract:
This thesis is an ethnography and occupational folklife study of a treeplanting camp in
northwestern Ontario. Two main areas of inquiry are pursued. Robert McCarl's
concept of ''technique" is used to understand the culture and social relations of
treeplanting as products of the work process. Liminal space/time is investigated as
both a structuring principle of treeplanting and a product of the lived relations of
planters. The position of liminality in relation to complex society and work culture is
investigated and a study of liminality in praxis is proposed as a ntethodology for
approaching treeplanting. Finally, issues of personal and occupational identity
construction are examined in relation to both technique and liminality. Throughout
this thesis the contexts of youth and wage work. and issues surrotmding gender~
sexuality, class and age are integrated into various aspects of the occupation. Two
broad conclusions can be extrapolated from my research: piecework and liminal
space/time are the two main structures affecting the lives of treeplanters~ and the use
of the occupation as an instrumental site of experimentation affects both the labourer
and occupation's identity. These conclusions remain provisional because a lack of data
makes a comparative study of other treeplanting camps impossible at this tlme.

abstract:
A ferry transportation system consists of many factors, which interact in a
complex manner. Such a system is very difficult to analyze analytically. A computer
simulation is thus an appropriate method to aid in understanding the system and its
design.
The Province of Maluku, which consists of thousands of islands spread
haphazardly, has suffered from having an ineffective sea transportation system. A good
sea transportation system is essential for the development of this island province.
The purpose of this study is to analyze a ferry transportation system suitable for
the Province of Maluku. As an initial step, the study proposes to model ferry traffic
between a major port Ambon and nine outlying smaller communities on surrounding
islands.
The performance of the ship to be measured is the time spent during its annual
operation, that is, travelling/voyage time at sea, waiting time at the offing, and service
time at a dock in a port. The other performance of the ships to be measured is the annual
number of trip needed by a particular ship to carry the annual quantity of commodity. In
doing so, a computer model written in MODSIM III is used to support decision-making.
Since the actual commodity data were inaccessible, a very general model was
developed which can be utilized under any conditions, making the model very flexible to
changing. The model will be run under some configurations, which includes the use of
five different types of ship and its quantity in a particular route. A trial and error
procedure will be carried out in order to obtain several optimum performances of ships in
the whole system.

abstract:
The health utilization and death rates were captured for the family members of
disabled individuals over a fifteen-year period to determine if exposure to disability in the
family manifests poor health outcomes. Data from the Newfoundland Adult Health
Survey (1995) was linked to fifteen years, 1995- 2010, of provincial health administrative
data including hospital data, physician claims, and death records from the provincial
health care system. The health records and survey data were analyzed in relation to the
disability exposure burden experienced when a family member is disabled. The level of
disability exposure burden was quantified based on the addition of individual disability
scores for each family member. Disability exposure burden was associated with increased
number of hospital separations, total hospitalization days and the number of physician
visits, both General Practitioner and Specialist (p<0.1) but there was no association
between death (p>0.1) and disability exposure burden. Family members of disabled
individuals experienced increased rates of hospital separations, hospitalization days, and
physician visits suggesting that deleterious health outcomes may be introduced when
individuals are exposed to disability in the family unit.

abstract: Data integration systems offer uniform access to a set of autonomous and heterogeneous data sources. One of the main challenges in data integration is reconciling semantic differences among data sources. Approaches that been used to solve this problem can be categorized as schema-based and attribute-based. Schema-based approaches use schema information to identify the semantic similarity in data; furthermore, they focus on reconciling types before reconciling attributes. In contrast, attribute-based approaches use statistical and structural information of attributes to identify the semantic similarity of data in different sources. This research examines an approach to semantic reconciliation based on integrating properties expressed at different levels of abstraction or granularity using the concept of property precedence. Property precedence reconciles the meaning of attributes by identifying similarities between attributes based on what these attributes represent in the real world. In order to use property precedence for semantic integration, we need to identify the precedence of attributes within and across data sources. The goal of this research is to develop and evaluate a method and algorithms that will identify precedence relations among attributes and build property precedence graph (PPG) that can be used to support integration.

Masters thesis, Memorial University of Newfoundland.

abstract: This thesis analyses the potential of wood biochar as an adsorbent in removal of sulphate from produced water. In worldwide offshore oil and gas industry, a large volume of waste water is generated as produced water. Sulphur compounds present in these produced water streams can cause environmental problems, regulatory problems and operational issues. Among the various sulphur removal technologies, the adsorption technique is considered as a suitable method since the design is simple, compact, economical and robust. Biochar has been studied as an adsorbent for removal of contaminants from water in a number of studies due to its low cost, potential availability, and adsorptive characteristics. In this study, biochar produced through fast pyrolysis of bark, hardwood sawdust, and softwood sawdust were characterized through a series of tests and were analysed for adsorbent properties. Treating produced water using biochar sourced from wood waste is a two-fold solution to environmental problems as it reduces the volume of these wastes. Batch adsorption tests were carried out to obtain adsorption capacities of each biochar sample using sodium sulphate solutions. The highest sulphur adsorption capacities obtained for hardwood char, softwood char and bark char were 11.81 mg/g, 9.44 mg/g, and 7.94 mg/g respectively at 10 °C and pH=4. The adsorption process followed the second order kinetic model and the Freundlich isotherm model. Adsorption reaction was thermodynamically favourable and exothermic. The overall analysis concludes that the wood biochar is a feasible, economical, and environmental adsorbent for removal of sulphate from produced water.

abstract:
La société québécoise a véritablement atteint sa majorité durant le vinkrtieme siécle possiblement plus que tout autre secteur de la population canadienne. Accompagnent cette
maturation de nombreux changements sociaux et économiques qui ont engendre des
sentiments de dénaturation et d'aliénation et qui, sur le plan artistique, ont été reflétés dans
la littérature québécoise (francophone). Si le théâtre a commencé a exprimer ces sentiments
par la classe ouvriere urbaine et par son parler populaire à partir de la parution des Belles-Sœurs
 de Michel Tremblay, la littérature romanesque avait fait de mème une vingtaine
d'annees plus tòt par le biais de certains écrivains tels Gabrielle Roy et Roger Lemelin
mème si la langue populaire exclut, pour le moment, le joual. Les Plouffe de Lemelin
compte parmi les premiers romans quebécois dits urbains.

Afin d'échapper aux sentiments d'alienation et de dénaturation, les membres de la
société québécoise dont il est question dans Les Plouffe essaient tous de se démarquer de la
norme familiale dans un élan d'individuation. Mais cette derniere se révéle impuissante dans le cadre spatio-temporel du roman. Ce n'est qu'en élargissant effectivement l'aspect
spatial de ce cadre que les individus ont une assez bonne chance de réussir dans leur quéte
d'individuation. Ce travail essaiera de révéler la nature de cette quète au moyen de deux
perspectives sémiotiques différentes mais complementaires : la semiotique discursive et la
sémiotique narrative. La première partie, celle de la sémiotique discursive, se divise en
quatre chapitres qui, ensemble, mettront en évidence la pertinence du récit au niveau de
l'expresston : la discursivisation, au moyen de l'actorialisation et de la spatialisation, et
l'organisation discursive. La seconde partie, celle de la semiotique narrative, comprend
deux chapitres qui visent a exposer l'importance du contenu du récit en matiere de l'actance,
qui étudie non pas l'acteur mais la fonction de l'acteur dans le recit, et en matiére de la
signification, qui découle de l'analyse actantielle. Ce travail ne se veut donc pas une étude
semiotique compléte : les niveaux intermèdiaire et profond de la syntaxe narrative ne sont
guère abordés ici, sans pour autant suggérer qu'ils ne mériteraient pas d'ètre explorés dans
une étude ultérieure.

Dysphagia, or difficulty in swallowing, poses a major health threat if it is not promptly diagnosed and treated. Problems secondary to dysphagia may include malnutrition, aspiration pneumonia dehydration, psychosocial problems and increased health care costs secondary to professional time for feeding, treatment of medical complications, food wastage, and the length of time required to feed residents. The objectives of this research were to 1) determine the prevalence of dysphagia population in a long-term care institution in St. John's, Newfoundland. Other objectives were to determine the medical diagnoses and conditions associated with dysphagia, to assess the extent of complications secondary to dysphagia and to document management techniques currently being used.
Information for this retrospective, descriptive study was obtained by medical record review and a questionnaire completed by nursing personnel. The study population consisted of 193 subjects (138 female/55 male) with a mean age of 75.6 years. Identification of dysphagia and the level of severity were based on the following: signs and symptoms of dysphagia, history of aspiration pneumonia, diagnosed neurological condition, documented reports of dysphagia, medical complications, and dietary modifications.
The prevalence of dysphagia was 45.5%. Of the subjects with dysphagia, 56%, 39% and 6% were mildly, moderately and severely dysphagic, respectively. For only 22% of dysphagic subjects was dysphagia documented in the medical record. Nursing staff identified only 39% of subjects with dysphagia. They were able to identify all severely dysphagic subjects.
Dysphagia was associated with fluid and texture modifications; poor hydration status; nursing reports of subjects being "not well nourished"; use of nutritional supplements, poor skin integrity; the need for crushed medications; impaired chewing ability; feeding dependency; and level of assistance required at meal time. Dysphagia was not associated with age; sex; inadequate nutritional intake; decubitus ulcers; length of time to be fed; weight status; use of antipsychotic or tricyclic antidepressant medications; difficulty swallowing medications; reports of "not being hungry"; and needing encouragement to eat. Due to small numbers it was possible to examine associations of dysphagia with medical conditions. Recommendations are provided for future management of dysphagic individuals in long-term care facilities.

abstract:
Of the components of the respiratory system, one of the most crucial is the
pulmonary surfactant. This mixture of phospholipids, cholesterol, and proteins act to
reduce surface tension inside the lungs as well as fight infection. The surfactant
associated proteins vary in their structure and function but the most important is
surfactant protein B (SP-B) which is essential to life. Despite its importance, it has not
yet been structurally characterized and as a result, its function still remains a mystery.
Part of the problem is the difficulty in acquiring enough of the protein to work with. To
attempt to solve this problem, a method has been developed to recombinantly express
a variant of human SP-B in Escherichia coli in relative abundance. Also, a series of
functional tests on the recombinant SP-B were completed to determine if it is a viable
alternative to native SP-B for use in the laboratory and possible clinical applications.
The functional tests included membrane leakage and lipid mixing assays, as well as
captive bubble surfactometer studies. These experiments revealed that the recombinant
SP-B displayed normal SP-B activity albeit not as effective as native SP-B.

abstract:
This thesis is an extension of an Honors thesis written at the Archaeology Unit at
Memorial University of Newfoundland (Cave 1998). It concerns the great number of
petroglyphs found around Kejimkujik Lake in western Nova Scotia. These rock carvings
have been attributed to the Mi 'kmaw who have inhabited the Maritimes from the precontact
period to the present day.
There were three main objectives in this research. The first was to assess the
importance of landscape in creating the context for the drawing of the petroglyphs. The
second objective was to gain insights of contemporary Mi 'kmaq regarding the modern
significance of the petroglyphs. And fmally, a direct comparison with recent tracings
was made to assess the loss of petroglyphs to erosion and graffiti since they were first
recorded in 1888 by George Creed. These objectives will provide a fresh perspective into
the research of the Mi 'kmaw petroglyphs.

abstract:
The emergence of the human rights paradigm has been the most profound
development in redefining the relationship between citizens and the state in Canada.
In the sixties an explosion of new and vibrant social movements rocked Canada, from
gay liberationism to feminism. Among these social activists was a new generation of
civil liberties and human rights associations, dedicated to the defence of individual
freedoms and rights irrespective of individuals' background and beliefs. These 'rights
associations' emerged in every province in Canada and came to be the dominant
advocates for individual rights after they eclipsed the work of organized labour with
the decline of the Jewish Labour Committee in the 1970s. Despite a unity of purpose,
bitter debates raged within and among rights associations over questions of ideology,
the validity of state funding, and how to form a national rights association. Many of
these debates were characteristic ofthe obstacles facing all social movement
organizations in Canada in the sixties and seventies. This thesis explores the early
history of the four oldest surviving rights associations in Canada: The British
Columbia Civil Liberties Association, Ligue des droits de l'homme, The Canadian
Civil Liberties Association, and The Newfoundland-Labrador Human Rights
Association. Among the issues mobilizing these activists in the 1960s and 1970s
were censorship, drug laws, denominational education, police brutality, the October
crisis of 1970, and the rights of prisoners, natives and welfare recipients. These four case studies provide insights into both the development of a uniquely twentieth
century social movement and several controversial public debates during this period,
and demonstrate the power, and the limitations, of human rights activism.

abstract:
This paper admonishes school leadership to respond to today's rapidly changing world as
interconnectedness sweeps the globe. While school reform continues amid confusion and
diminishing public confidence, often because of weak leadership, organizations are transforming
into ' learning organizations' through systems thinking and transformed leadership, all within
natural law. This is part of a global metamorphosis as the Western psyche allows itself to
respond to its inner, intuitive voice. This paper argues for school leadership and school
leadership training institutions to break from tradition and thrust schooling to the fore as it
initiates acceleration of school transformation into values-driven learning communities grounded
in shared responsibility and framed within nature's ' spiritual templates'.

abstract:
Since the role of the cottage hospitals in the health care
delivery system is being questioned by health planners and health
professionals, this descriptive study examines the extent to which
the cottage hospital system continues to meet the health needs of
the people in two rural health districts. The study examines the
utilization of the cottage hospitals in a la-year time frame. Factors
which the population report as influencing their use or non-use of the
cottage hospital and their perceived needs for health care are examined.
In addition, opinions of health professional personnel in
relation to the present status of health care services in rural areas
and their perceived health service needs for the future are explored.
The health districts were chosen by selected criteria. A
random sample of the population in both districts and all health
professional personnel working in the districts were included in the
study.
Data on the utilization of the cottage hospitals were obtained
from the Department of Health. Data were collected from the population
sample and from the health professional personnel by means of
semi-structured interview guides designed by the investigator. Frequencies
were determined for all data, and compared between the two
districts. The results show a drastic decrease in the utilization
of the important services of the cottage hosp~tals in both districts,
the highest utilization rates being for individuals in the 0-14 and 65 years plus age groups, and obstetrical patients. The utilization
of the Out-Patient department has decreased where there are private
physicians in practice, but increased where this service was not
available.
Common factors emerging from the data were the extent to which
the views and perspectives of the providers and the consumers of
health care in both districts were congruent in their suggestions and
comments regarding health care in the areas. Data from both groups
suggest that neither group view the cottage hospital as an acute care
hospital but rather as a primary care facility offering Out-Patient
care, diagnostic, emergency, obstetrical and basic pediatric services
with appropriate referrals, and with emphasis on the need for public
health education and community out-reach programs.
This descriptive study has gathered baseline data and examined
the continuing functions of cottage hospitals. It has explored opinions
on health care and of the perceived health care service needs of the
population and of the health professionals in two defined health
districts and has provided direction for future ·study.

abstract:
In this thesis, two recently proposed modes of operation for block ciphers,
referred to as statistical cipher feedback (SCFB) mode and optimized cipher feedback
(OCFB) mode, are investigated. Both cipher modes can achieve the capability of selfsynchronization
to recover from bit slips or insertions in the communication channel
automatically. Compared to CFB mode, both cipher modes can obtain higher efficiency
with modest buffer size and reasonable latency. Hence, both modes can be applied to
high-speed digital hardware implementation and they have been identified as being
suitable for physical layer security for applications such as SONET/SDH.
In this thesis, both modes are implemented in software and hardware. In
particular, the hardware structure and method of hardware implementation are
investigated. Parallel and serial transfers are applied to the hardware implementation of
SCFB mode and OCFB mode, respectively. Very High Speed Integrated Circuit
Description Language (VHDL) and LSI design with 0.18 CMOS technology supported
by Canadian Microelectronics Corporations (CMC) are used in the process of hardware
implementation. The hardware structures of both modes are synthesized by using
Synopsis tools provided by CMC as well.
In addition, the performances of both modes are analyzed with respect to
characteristics such as the theoretical efficiency, synchronization recovery delay, and the
error propagation factor. Furthermore, the relationship between efficiency, probability of queue overflow, and buffer size is investigated. It is definite that both of modes can
obtain higher efficiency than cipher feedback mode. OCFB mode performs marginally
better with respect to error propagation and synchronization recovery delay in some
circumstances. SCFB mode is able to achieve higher efficiency with a given buffer size
and probability of buffer overflow in an efficient hardware implementation. Similarly, for
a given efficiency and buffer size, SCFB mode has a lower probability of buffer overflow
than OCFB mode. In fact, while for SCFB it is possible to guarantee no overflow with
50% efficiency and a buffer size equal to the block size, it is not possible to guarantee no
overflow for efficiencies that are much less than 50% for OCFB mode. These results
imply that SCFB is a mode more suitable for high speed physical layer security than
OCFB mode.

abstract:
We consider a class of initial data sets (Σ,h,K) for the Einstein constraint equations
which we define to be generalized Brill (GB) data. This class of data is simply
connected, U(1)²-invariant, maximal, and four-dimensional with two asymptotic ends.
We study the properties of GB data and in particular the topology of Σ. The GB
initial data sets have applications in geometric inequalities in general relativity. We
construct a mass functional M for GB initial data sets and we show:(i) the mass of any
GB data is greater than or equals M, (ii) it is a non-negative functional for a broad
subclass of GB data, (iii) it evaluates to the ADM mass of reduced t − φi symmetric
data set, (iv) its critical points are stationary U(1)²-invariant vacuum solutions to
the Einstein equations. Then we use this mass functional and prove two geometric
inequalities: (1) a positive mass theorem for subclass of GB initial data which includes
Myers-Perry black holes, (2) a class of local mass-angular momenta inequalities for
U(1)²-invariant black holes. Finally, we construct a one-parameter family of initial
data sets which we show can be seen as small deformations of the extreme Myers-
Perry black hole which preserve the horizon geometry and angular momenta but have
strictly greater energy.

abstract: Anthropogenic emissions of carbon dioxide are causing an overall decrease of ocean pH, now termed ocean acidification (OA). This change in water chemistry has potentially dire implications for organisms living in marine environments, especially at high latitudes where carbonate saturation states are already low. OA has been shown to affect processes such as calcification, physiology, reproduction and development, with species-specific differences being observed. The goal of the present study was to better understand the effects of OA on weakly calcifying, cold-water species with lecitotrophic larvae, using the sea cucumber Cucumaria frondosa. In addition, it aimed to gain information on how OA might affect deep-sea organisms, using the hermaphroditic polychaete Ophryotrocha sp. Focal species were exposed to a ~0.4 unit decrease in pH for 19-26 weeks using a realistic flow-through system. I then investigated the reproductive output of each species, as well as its behaviour, spawning, larval development and calcification. Lipid and fatty acid profiles were also examined in C. frondosa. Findings varied between the two species. Gamete synthesis was disrupted by low pH in C. frondosa. Consequently, mature oocytes exhibited morphological discrepancies and negative buoyancy, leading to high embryonic mortality. Skeletal ossicles were affected in terms of abundance, microstructural appearance and chemical composition. In comparison, Ophryotrocha sp. exhibited a decrease in spermatozoa production but an increase in the number and size of oocytes under low pH. There was a trend towards a lower effective fecundity and development appeared to be slower under OA conditions, however these observations will require further investigation. The present analysis contributes to a growing understanding of the potential impacts of predicted near future OA gathered through long-term transgenerational exposure. It will assist in filling gaps in OA research pertaining to weakly calcifying species from cold-water and deep-sea environments that rely on lecithotrophic (maternally-provisioned) development. Together, the results suggest that these species may undergo significant challenges under future OA conditions, with cascading effects on the environments of which they are vital components.

abstract:
This thesis explores the character of Hamlet in Shakespeare's same-titled
work in the light of certain aspects of stoicism and medieval Christian
philosophy. Throughout the course of the play we see Hamlet struggling with
his thoughts. At first he deliberates without taking action as a consequence of
his reasoning, but in the later stages of the play he gives in to passion, which
ultimately leads to his own demise. The thesis gives an account of certain
aspects of both philosophies that are displayed in the play and shows how those
ideas influence the character of Hamlet and contextualize his personal tragedy.
Hamlet fails to follow the philosophies that he praises and to grow as a
character by overcoming his passions over the course of the play.

abstract:
“Availability” is the terminology used in asset intensive industries such as petrochemical and hydrocarbons processing to describe the readiness of equipment, systems or plants to perform their designed functions. It is a measure to suggest a facility’s capability of meeting targeted production in a safe working environment. Availability is also vital as it encompasses reliability and maintainability, allowing engineers to manage and operate facilities by focusing on one performance indicator. These benefits make availability a very demanding and highly desired area of interest and research for both industry and academia.
In this dissertation, new models, approaches and algorithms have been explored to estimate and manage the availability of complex hydrocarbon processing systems. The risk of equipment failure and its effect on availability is vital in the hydrocarbon industry, and is also explored in this research. The importance of availability encouraged companies to invest in this domain by putting efforts and resources to develop novel techniques for system availability enhancement. Most of the work in this area is focused on individual equipment compared to facility or system level availability assessment and management. This research is focused on developing an new systematic methods to estimate system availability. The main focus areas in this research are to address availability estimation and management through physical asset management, risk-based availability estimation strategies, availability and safety using a failure assessment framework, and availability enhancement using early equipment fault detection and maintenance scheduling optimization.

Masters thesis, Memorial University of Newfoundland.

abstract:
This research uses scanning electron microscopy-energy dispersive X-ray
spectrometry (SEM-EDX) and inductively coupled plasma-mass spectrometry (ICP-MS)
on cross-sections of iron artifacts sectioned from along shafts to determine the elemental
constituents of a collection of Inuit and European artifacts from along the coast of
Labrador. Hand-wrought iron nails from early historic period (16th – 18th centuries CE)
Inuit sites in Labrador were originally manufactured by and acquired from early whalers
and fishers of various European nationalities. The purpose of this research was to assess if
the elements in different samples are sufficiently homogeneous to be viable for a
provenience analysis to discern which Inuit nails were originally derived from which
European groups; the Basque, English or French. The consistent relationships between
the geochemical signatures of iron nails found in Inuit sites and historic nails derived
from specific European groups could provide insights into the prevalence, activity and the
nature of indigenous interactions of different European nationalities in the region over
time. The results show that the methods applied to evaluate the geochemistry of the nails
was not sufficient to detect meaningful patterns because the nails did not demonstrate the
necessary degree of chemical uniformity among different samples in the same artifacts.

Masters thesis, Memorial University of Newfoundland.

abstract: A cemetery associated with the St. John’s Royal Naval Hospital, NL (~1725-1825) was partially excavated in 1979, uncovering the skeletal remains of at least 21 individuals. Isotopic analyses (δ¹³Cvpdb, δ¹⁵Nair, δ¹⁸Ovpdb, and ⁸⁷Sr/⁸⁶Sr) were used to examine the diet and geographic origins of these individuals and compare them with recent results from other British Naval cemeteries. Their origins according to enamel carbonates and ⁸⁷Sr/⁸⁶Sr are mainly consistent with the British Isles and the bone collagen values were largely consistent with naval rations. There was some variability in δ¹⁵Nair and δ¹³Cvpdb values, suggesting different social classes and the consumption of C₄ foods associated with North America. While this study has highlighted deficiencies in the ability of isotopic analyses to define the variability within naval rations, it is the first to examine origins of early modern naval sailors isotopically, as well as the experiences of these sailors within the context of Newfoundland.

abstract:
This thesis reports on a novel method to build a 3-D model of the above-water portion
of icebergs using surface imaging. The goal is to work towards the automation of
iceberg surveys, allowing an Autonomous Surface Craft (ASC) to acquire shape and size
information. After collecting data and images, the core software algorithm is made up of
three parts: occluding contour finding, volume intersection, and parameter estimation. A
software module is designed that could be used on the ASC to perform automatic and fast
processing of above-water surface image data to determine iceberg shape and size measurement
and determination. The resolution of the method is calculated using data from
the iceberg database of the Program of Energy Research and Development (PERD). The
method was investigated using data from field trials conducted through the summer of 2014
by surveying 8 icebergs during 3 expeditions. The results were analyzed to determine iceberg
characteristics. Limitations of this method are addressed including its accuracy. Surface
imaging system and LIDAR system are developed to profile the above-water iceberg
in 2015.

Masters thesis, Memorial University of Newfoundland.

abstract:
Produced water is a by-product of offshore oil and gas production, and is released
in large volumes when platforms are actively processing crude oil. Some pollutants are
not typically removed by conventional oil/water separation methods and are discharged
with produced water. Oil and grease can be found dispersed in produced water in the form
of tiny droplets, and polycyclic aromatic hydrocarbons (PAHs) are commonly found
dissolved in produced water. Both can have acute and chronic toxic effects in marine
environments even at low exposure levels. The analysis of the dissolved and dispersed
phases are a priority, but effort is required to meet the necessary detection limits.
There are several methods for the analysis of produced water for dispersed oil and
dissolved PAHs, all of which have advantages and disadvantages. In this work, EPA
Method 1664 and APHA Method 5520 C for the determination of oil and grease will be
examined and compared. For the detection of PAHs, EPA Method 525 and PAH MIPs
will be compared, and results evaluated.
APHA Method 5520 C Partition-Infrared Method is a liquid-liquid extraction
procedure with IR determination of oil and grease. For analysis on spiked samples of
artificial seawater, extraction efficiency ranged from 85 – 97%. Linearity was achieved in
the range of 5 – 500 mg/L. This is a single-wavelength method and is unsuitable for
quantification of aromatics and other compounds that lack sp³-hybridized carbon atoms.
EPA Method 1664 is the liquid-liquid extraction of oil and grease from water samples
followed by gravimetric determination. When distilled water spiked with reference oil was extracted by this procedure, extraction efficiency ranged from 28.4 – 86.2%, and
%RSD ranged from 7.68 – 38.0%.
EPA Method 525 uses solid phase extraction with analysis by GC-MS, and was
performed on distilled water and water from St. John’s Harbour, all spiked with
naphthalene, fluorene, phenanthrene, and pyrene. The limits of detection in harbour water
were 0.144, 3.82, 0.119, and 0.153 g/L respectively. Linearity was obtained in the range
of 0.5-10 g/L, and %RSD ranged from 0.36% (fluorene) to 46% (pyrene).
Molecularly imprinted polymers (MIPs) are sorbent materials made selective by
polymerizing functional monomers and crosslinkers in the presence of a template
molecule, usually the analytes of interest or related compounds. They can adsorb and
concentrate PAHs from aqueous environments and are combined with methods of
analysis including GC-MS, LC-UV-Vis, and desorption electrospray ionization (DESI)-
MS. This work examines MIP-based methods as well as those methods previously
mentioned which are currently used by the oil and gas industry and government
environmental agencies. MIPs are shown to give results consistent with other methods,
and are a low-cost alternative improving ease, throughput, and sensitivity. PAH MIPs
were used to determine naphthalene spiked into ASTM artificial seawater, as well as
produced water from an offshore oil and gas operation. Linearity was achieved in the
range studied (0.5 – 5 mg/L) for both matrices, with R² = 0.936 for seawater and R² =
0.819 for produced water. The %RSD for seawater ranged from 6.58 – 50.5% and for
produced water, from 8.19 – 79.6%.

Masters thesis, Memorial University of Newfoundland.

abstract:
Fine-grained sedimentary rocks are very common and play an important role as source
rocks in conventional hydrocarbon plays and combined source rocks and reservoirs in
unconventional shale gas plays. Recent research has revealed that organic carbon-rich
examples are much more heterogeneous than most authors have previously assumed. Despite
appearing largely homogeneous at hand specimen scales, they are actually organized into very
thin, sharp-based, occasionally bioturbated beds that systematically upward-coarsen and fine
on metre scales. The presence of this heterogeneity profoundly impacts how geologists
interpret both the fundamental mechanisms responsible for organic carbon enrichment in these
successions, how long-term stratigraphic processes are interpreted to control facies variability,
and suggest that the relative importance of persistent bottom water anoxia and that the
existence of a low energy water column have been over estimated.
This study is focused on the Posidonia Fm., a Jurassic (Toarcian) mudstone succession
located within the Lower Saxony Basin, Germany. The Posidonia Fm. was chosen because this
succession, and its global equivalents distributed throughout Europe, South America, and
North America, are considered to be a classical example of an Oceanic Anoxic Event (Jenkyns,
1988). Additionally, the availability of two Posidonia Fm. cores with correlative wire line log
suites allowed for an integrated lithofacies-wireline log assessment.
The organic-carbon rich lithofacies present in the Posidonia Formation was
investigated to determine (a) the extent of lithofacies variability present, (b) the fundamental
physical, chemical and biological controls that might be responsible for this variability, (c)
whether this succession can be reasonably interpreted in terms of sequence stratigraphic
principles, and (d) the appropriateness of using wireline logs to characterize this variability.
The necessary textural and mineralogical data to investigate these aims were obtained using
petrographic, scanning electron microscope, x-ray diffraction data, and total organic carbon
data coupled with a suite of wire line logs (gamma ray, neutron porosity, sonic, density, and
resistivity logs).
Seven lithofacies were identified and are characterized by varying proportions of
detrital and production-derived rock components, diagenetic features, grain size variations and
variable textures and bedding fabrics. These lithofacies are organized into thin mm-scale beds
that systematically stack into m-units that are variously increasingly silt-rich, clay-rich or
calcareous nannoplankton-rich. The deposition of normally-graded beds with sharp bases are
interpreted to be related to storm deposition, and evidence of ripple deposition suggests that
depositional conditions were more energetic than previously assumed. Sand-rich ripples
suggest that advective transport mechanisms were operating in addition to suspension settling
processes. Stacked successions progressively enriched (or depleted) in detrital components
relative to production-derived components and exhibiting evidence of increasing (or
decreasing) energy conditions have been determined to be component parts of overall
highstand ( and transgressive) systems tracts.
Stacked successions characterized by systematic facies variability correlate to
increasing and decreasing trends in the gamma-ray, density, sonic, neutron, and resistivity
wireline logs. The sensitivity of the logs to mineralogy means that systematic lithological
variations can be related to wireline trends. Cross-plots of neutron, sonic, density and
resistivity log data appear to broadly discriminate between facies. A single log cannot be relied
upon to extract useful facies information, an integrated approach using two or more logs is
much more effective.

abstract: The purpose of this study was to investigate the effect of a fall prevention program on older adults as well as to explore the perceptions of older adults have on fall risk and the fall prevention program. This research was completed in Newfoundland and Labrador, Canada with participants above the age of 65. The 10-week fall prevention program focused on balance, strength, and flexibility and was followed by focus groups with the control and intervention groups. Pre and post-test measures (postural sway, TUG test, foam and dome test, ABC Scale, ESE Scale, FES Scale, SAFFE) were completed to determine if the fall prevention program decreased fall risk. The results of the quantitative portion of the study did not produce significant results however the qualitative portion was very informative. Five themes emerged from the focus group data: risk factor awareness, confidence, connectedness, quality of life, and program promotion. This research highlights the importance of fall prevention programs for older adults, not only to keep them healthy, but also for the personal and social benefits they facilitate.

abstract:
The sudden hydrocarbon influx from the formation into the wellbore poses a serious risk to the safety of the well. This sudden influx is termed a kick, which, if not controlled, may lead to a blowout. Therefore, early detection of the kick is crucial to minimize the possibility of a blowout occurrence. There is a high probability of delay in kick detection, apart from other issues when using a kick detection system that is exclusively based on surface monitoring. Down-hole monitoring techniques have a potential to detect a kick at its early stage. Down-hole monitoring could be particularly beneficial when the influx occurs as a result of a lost circulation scenario. In a lost circulation scenario, when the down-hole pressure becomes lower than the formation pore pressure, the formation fluid may starts to enter the wellbore. The lost volume of the drilling fluid is compensated by the formation fluid flowing into the well bore, making it difficult to identify the kick based on pit (mud tank) volume observations at the surface. This experimental study investigates the occurrence of a kick based on relative changes in the mass flow rate, pressure, density, and the conductivity of the fluid in the down-hole. Moreover, the parameters that are most sensitive to formation fluid are identified and a methodology to detect a kick without false alarms is reported.
Pressure transmitter, the Coriolis flow and density meter, and the conductivity sensor are employed to observe the deteriorating well conditions in the down-hole. These observations are used to assess the occurrence of a kick and associated blowout risk. Monitoring of multiple down-hole parameters has a potential to improve the accuracy of interpretation related to kick occurrence, reduces the number of false alarms, and provides a broad picture of down-hole conditions. The down-hole monitoring techniques have a potential to reduce the kick detection period.
A down-hole assembly of the laboratory scale drilling rig model and kick injection setup were designed, measuring instruments were acquired, a frame was fabricated, and the experimental set-up was assembled and tested. This set-up has the necessary features to evaluate kick events while implementing down-hole monitoring techniques. Various kick events are simulated on the drilling rig model. During the first set of experiments compressed air (which represents the formation fluid) is injected with constant pressure margin. In the second set of experiments the compressed air is injected with another pressure margin. The experiments are repeated with another pump (flow) rate as well.
This thesis consists of three main parts. The first part gives the general introduction, motivation, outline of the thesis, and a brief description of influx: its causes, various leading and lagging indicators, and description of the several kick detection systems that are in practice in the industry. The second part describes the design and construction of the laboratory scale down-hole assembly of the drilling rig and kick injection setup, which is used to implement the proposed methodology for early kick detection. The third part discusses the experimental work, describes the methodology for early kick detection, and presents experimental results that show how different influx events affect the mass flow rate, pressure, conductivity, and density of the fluid in the down-hole, and the discussion of the results. The last chapter contains summary of the study and future research.

abstract:
In this thesis, we introduce DeReEs-4v, an algorithm for unsupervised and automatic
registration of two video frames captured depth-sensing cameras. DeReEs-4V receives
two RGBD video streams from two depth-sensing cameras arbitrary located in an
indoor space that share a minimum amount of 25% overlap between their captured
scenes. The motivation of this research is to employ multiple depth-sensing cameras
to enlarge the field of view and acquire a more complete and accurate 3D information
of the environment. A typical way to combine multiple views from different cameras
is through manual calibration. However, this process is time-consuming and may
require some technical knowledge. Moreover, calibration has to be repeated when the
location or position of the cameras change.
In this research, we demonstrate how DeReEs-4V registration can be used to find
the transformation of the view of one camera with respect to the other at interactive
rates. Our algorithm automatically finds the 3D transformation to match the
views from two cameras, requires no human interference, and is robust to camera
movements while capturing. To validate this approach, a thorough examination of
the system performance under different scenarios is presented. The system presented
here supports any application that might benefit from the wider field-of-view provided
by the combined scene from both cameras, including applications in 3D telepresence,
gaming, people tracking, videoconferencing and computer vision.

abstract:
Human hepatic lipase (hHL) is bound to the cell surface via heparan sulfate proteoglycans
(HPSGs) and hydrolyzes triglycerides and phospholipids within circulating lipoproteins.
High-density lipoprotein (HDL) transports excess extrahepatic cholesterol to the liver for
excretion. However, small lipid-deficient HDL generated by hHL action has the ability to
accept more cholesterol. I hypothesized that a peptide mimicking the cell surface
associations of hHL will displace hHL from cell surfaces, increasing its activity in cell
culture media. To test this hypothesis, I have recombinantly expressed and purified a
tagged mimetic peptide, encompassing the major heparin-binding domain of hHL. Results
from in vitro lipase displacement assays showed that the peptide has an ability to displace
active HPSG associated lipases. Data from proton nuclear magnetic resonance experiments
showed that structural changes occur in the peptide in the presence of heparin. Overall,
these data provide a foundation to use mimetic peptides for the displacement of cell
surface associated lipases.

abstract:
The main focus of this thesis is to address the relative localization problem of a
heterogenous team which comprises of both ground and micro aerial vehicle robots.
This team configuration allows to combine the advantages of increased accessibility
and better perspective provided by aerial robots with the higher computational and
sensory resources provided by the ground agents, to realize a cooperative multi robotic
system suitable for hostile autonomous missions. However, in such a scenario, the
strict constraints in flight time, sensor pay load, and computational capability of micro
aerial vehicles limits the practical applicability of popular map-based localization
schemes for GPS denied navigation. Therefore, the resource limited aerial platforms
of this team demand simpler localization means for autonomous navigation.
Relative localization is the process of estimating the formation of a robot team using
the acquired inter-robot relative measurements. This allows the team members to
know their relative formation even without a global localization reference, such as
GPS or a map. Thus a typical robot team would benefit from a relative localization
service since it would allow the team to implement formation control, collision
avoidance, and supervisory control tasks, independent of a global localization service.
More importantly, a heterogenous team such as ground robots and computationally
constrained aerial vehicles would benefit from a relative localization service since it
provides the crucial localization information required for autonomous operation of the weaker agents. This enables less capable robots to assume supportive roles and contribute
to the more powerful robots executing the mission. Hence this study proposes
a relative localization-based approach for ground and micro aerial vehicle cooperation,
and develops inter-robot measurement, filtering, and distributed computing modules,
necessary to realize the system.
The research study results in three significant contributions. First, the work designs
and validates a novel inter-robot relative measurement hardware solution which has
accuracy, range, and scalability characteristics, necessary for relative localization. Second,
the research work performs an analysis and design of a novel nonlinear filtering
method, which allows the implementation of relative localization modules and attitude
reference filters on low cost devices with optimal tuning parameters. Third, this work
designs and validates a novel distributed relative localization approach, which harnesses
the distributed computing capability of the team to minimize communication
requirements, achieve consistent estimation, and enable efficient data correspondence
within the network. The work validates the complete relative localization-based system
through multiple indoor experiments and numerical simulations.
The relative localization based navigation concept with its sensing, filtering, and distributed
computing methods introduced in this thesis complements system limitations
of a ground and micro aerial vehicle team, and also targets hostile environmental conditions.
Thus the work constitutes an essential step towards realizing autonomous
navigation of heterogenous teams in real world applications.

abstract:
Bicellar lipid mixture dispersions progressively coalesce to larger structures on warming.
This phase behaviour is particularly sensitive to interactions that perturb bilayer properties.
In this study, ²H NMR was used to study the perturbation of bicellar lipid mixtures
by two peptides (SP-B₆₃₋₇₈, a lung surfactant protein fragment and Magainin 2, an antimicrobial
peptide) which are structurally similar. Particular attention was paid to the relation
between peptide-induced perturbation and lipid composition.
In bicellar dispersions containing only zwitterionic lipids (DMPC-d₅₄/DMPC/DHPC
(3:1:1)) both peptides had little to no effect on the temperature at which coalescence to
larger structures occurred. Conversely, in mixtures containing anionic lipids
(DMPC-d₅₄/DMPG/DHPC (3:1:1)), both peptides modified bicellar phase behaviour. In
mixtures containing SP-B₆₃₋₇₈, the presence of peptide decreased the temperature of the
ribbon-like to extended lamellar phase transition. The addition of Magainin 2 to DMPCd₅₄/
DMPG/DHPC (3:1:1) mixtures, in contrast, increased the temperature of this transition
and yielded a series of spectra resembling DMPC/DHPC (4:1) mixtures. Additional studies
of lipid dispersions containing deuterated anionic lipids were done to determine whether
the observed perturbation involved a peptide-induced separation of zwitterionic and anionic
lipids. Comparison of DMPC/DMPG-d₅₄/DHPC (3:1:1) and DMPC-d₅₄/DMPG/DHPC
(3:1:1) mixtures showed that DMPC and DMPG occupy similar environments in the presence
of SP-B₆₃₋₇₈, but different lipid environments in the presence of Magainin 2. This
might reflect the promotion of anionic lipid clustering by Magainin 2. These results demonstrate
the variability of mechanisms of peptide-induced perturbation and suggest that lipid
composition is an important factor in the peptide-induced perturbation of lipid structures.

Masters thesis, Memorial University of Newfoundland.

abstract:
Archaeological fish otoliths have the potential to serve as proxies for both season of site occupation and palaeoclimate conditions. By sampling along the distinctive sub-annual seasonal bands of the otolith and completing a stable isotope (δ¹⁸O, δ¹³C) analysis, variations within the fish’s environment can be identified. Through the analysis of cod otoliths from two archaeological sites on Kiska Island, Gertrude Cove (KIS-010) and Witchcraft Point (KIS-005), this research evaluates a micromilling methodological approach to extracting climatic data from archaeological cod otoliths. In addition, δ¹⁸Ootolith data and radiocarbon dates frame a discussion of Pacific cod harvesting, site occupation, and changing climatic conditions on Kiska Island. To aid in the interpretation of the archaeological Pacific cod results, archaeological and modern Atlantic cod otoliths were also analyzed as a component of this study to develop. The Atlantic cod otoliths provided the methodological and interpretative framework for the study, and also served to assess the efficacy of this sampling strategy for archaeological materials and to add time-depth to existing datasets.
The δ¹⁸Ootolith values successfully illustrate relative variation in ambient water temperature. The Pacific cod δ¹⁸O values demonstrate a weak seasonal signal identifiable up to year 3, followed by relatively stable values until year 6/7 when values continuously increase. Based on the δ¹⁸O values, the Pacific cod were exposed to the coldest water temperatures immediately prior to capture. The lack of a clear cycle of seasonal variation and the continued increase in values towards the otolith edge obscures the season of capture, and indicates that other behavioural, environmental, or methodological factors influenced the otolith δ¹⁸O values.
It is suggested that Pacific cod would have been harvested throughout the year, and the presence of cod remains in Aleutian archaeological sites cannot be used as a reliable indicator of summer occupation. In addition, when the δ¹⁸O otolith values are integrated with radiocarbon dates and known climatic regimes, it is demonstrated that climatic conditions play an integral role in the pattern of occupation at Gertrude Cove. Initial site occupation coincides with the end of a neoglacial cooling period, and the most recent and continuous occupation coincides with the end of a localized warming period and the onset of the Little Ice Age (LIA).

Masters thesis, Memorial University of Newfoundland.

abstract: My thesis examines fine-scale habitat use and movement patterns of age 1 Greenland cod (Gadus macrocephalus ogac) tracked using acoustic telemetry. Recent advances in tracking technologies such as GPS and acoustic telemetry have led to increasingly large and detailed datasets that present new opportunities for researchers to address fine-scale ecological questions regarding animal movement and spatial distribution. There is a growing demand for home range models that will not only work with massive quantities of autocorrelated data, but that can also exploit the added detail inherent in these high-resolution datasets. Most published home range studies use radio-telemetry or satellite data from terrestrial mammals or avian species, and most studies that evaluate the relative performance of home range models use simulated data. In Chapter 2, I used actual field-collected data from age-1 Greenland cod tracked with acoustic telemetry to evaluate the accuracy and precision of six home range models: minimum convex polygons, kernel densities with plug-in bandwidth selection and the reference bandwidth, adaptive local convex hulls, Brownian bridges, and dynamic Brownian bridges. I then applied the most appropriate model to two years (2010-2012) of tracking data collected from 82 tagged Greenland cod tracked in Newman Sound, Newfoundland, Canada, to determine diel and seasonal differences in habitat use and movement patterns (Chapter 3). Little is known of juvenile cod ecology, so resolving these relationships will provide valuable insight into activity patterns, habitat use, and predator-prey dynamics, while filling a knowledge gap regarding the use of space by age 1 Greenland cod in a coastal nursery habitat. By doing so, my thesis demonstrates an appropriate technique for modelling the spatial use of fish from acoustic telemetry data that can be applied to high-resolution, high-frequency tracking datasets collected from mobile organisms in any environment.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract:
The rainbow smelt (Osmerus mordax) is an anadromous teleost that produces type II antifreeze protein (AFP) and accumulates modest urea and high glycerol levels in plasma and tissues as adaptive cryoprotectant mechanisms in sub-zero temperatures. It is known that glyceroneogenesis occurs in liver via a branch in glycolysis and gluconeogenesis and is activated by low temperature; however, the precise mechanisms of glycerol synthesis and trafficking in smelt remain to be elucidated. The objective of this thesis was to provide further insight using functional genomic techniques [e.g. suppression subtractive hybridization (SSH) cDNA library construction, microarray analyses] and molecular analyses [e.g. cloning, quantitative reverse transcription - polymerase chain reaction (QPCR)].
Novel molecular mechanisms related to glyceroneogenesis were deciphered by comparing the transcript expression profiles of glycerol (cold temperature) and non-glycerol (warm temperature) accumulating hepatocytes (Chapter 2) and livers from intact smelt (Chapter 3). Briefly, glycerol synthesis can be initiated from both amino acids and carbohydrate; however carbohydrate appears to be the preferred source when it is readily available. In glycerol accumulating hepatocytes, levels of the hepatic glucose transporter (GLUT2) plummeted and transcript levels of a suite of genes (PEPCK, MDH2, AAT2, GDH and AQP9) associated with the mobilization of amino acids to fuel glycerol synthesis were all transiently higher. In contrast, in glycerol accumulating livers from intact smelt, glycerol synthesis was primarily fuelled by glycogen degradation with higher PGM and PFK (glycolysis) transcript levels. Whether initiated from amino acids or carbohydrate, there were common metabolic underpinnings. Increased PDK2 (an inhibitor of PDH) transcript levels would direct pyruvate derived from amino acids and / or DHAP derived from G6P to glycerol as opposed to oxidation via the citric acid cycle. Robust LIPL (triglyceride catabolism) transcript levels would provide free fatty acids that could be oxidized to fuel ATP synthesis. Increased cGPDH (glyceroneogenesis) transcript levels were not required for increased glycerol production, suggesting that regulation is more likely by post-translational modification. Finally, levels of a transcript potentially encoding glycerol-3-phosphatase, an enzyme not yet characterized in any vertebrate species, were transiently higher. These comparisons also led to the novel discoveries that increased G6Pase (glucose synthesis) and increased GS (glutamine synthesis) transcript levels were part of the low temperature response in smelt. Glucose may provide increased colligative protection against freezing; whereas glutamine could serve to store nitrogen released from amino acid catabolism in a non-toxic form and / or be used to synthesize urea via purine synthesis-uricolysis.
Novel key aspects of cryoprotectant osmolyte (glycerol and urea) trafficking were elucidated by cloning and characterizing three aquaglyceroporin (GLP)-encoding genes from smelt at the gene and cDNA levels in Chapter 4. GLPs are integral membrane proteins that facilitate passive movement of water, glycerol and urea across cellular membranes. The highlight was the discovery that AQP10ba transcript levels always increase in posterior kidney only at low temperature. This AQP10b gene paralogue may have evolved to aid in the reabsorption of urea from the proximal tubule.
This research has contributed significantly to a general understanding of the cold adaptation response in smelt, and more specifically to the development of a working scenario for the mechanisms involved in glycerol synthesis and trafficking in this species.

abstract: While mining is a major component of the northern Canadian economy, including the contemporary mixed economy of Aboriginal communities, it often leaves legacies of environmental and economic transformation that persist after closure. The legacies of historical mines in northern Canada challenge industry claims of sustainability. This thesis addresses how industrial mineral development and closure continue to affect local environments and economies after abandonment. The abandoned Pine Point mine in the Northwest Territories provides a case study for explaining the ongoing relationships among land cover, land use, and the post-industrial landscape. Drawing from landscape ecology and micropolitical ecology, I adopt an interdisciplinary approach to examine environmental and socioeconomic changes in the wake of industrial development and closure at Pine Point. The results show that passive reclamation is not sufficient for restoring ecological function in a subarctic environment. Land use, however, persists as land users adapt to the post-industrial landscape despite grave concern about its environmental condition. If mining is to be considered sustainable, decommissioning and reclamation must explicitly account for long-term environmental transformation as well as ongoing post-industrial land use, particularly in Aboriginal contexts.

abstract: This study concerns the Dublin Gulch intrusion-related gold system, Yukon Territory, Canada. Located 85 km, north northwest of the town of Mayo, YT, the property hosts a 3.3 M oz Au deposit associated with a mid-Cretaceous pluton. A detailed, 8 stage, hydrothermal paragenesis has been constructed for the deposit. At least two discrete fluids are responsible for sulfide mineralization at Dublin Gulch. The latter of the two hydrothermal fluids is responsible for the majority of Au endowment on the property. Geochemical signatures of mineralization support this finding, displaying distinct populations of arsenopyrite compositions and sulfur isotopes for each fluid. Lead isotopes from sulfosalts associated with the second fluid suggest hydrothermal scavenging from country rocks. Geochronology and petrogenetic studies show that a short lived intrusive event c. 93-94 Ma took place at Dublin Gulch and that the main Au mineralising fluid may be linked to a yet unseen intrusion at depth.

abstract:
This thesis stems from the project with real-time environmental monitoring company
EMSAT Corporation. They were looking for methods to automatically
ag spikes and
other anomalies in their environmental sensor data streams. The problem presents
several challenges: near real-time anomaly detection, absence of labeled data and
time-changing data streams. Here, we address this problem using both a statistical
parametric approach as well as a non-parametric approach like Kernel Density
Estimation (KDE).
The main contribution of this thesis is extending the KDE to work more effectively
for evolving data streams, particularly in presence of concept drift. To address
that, we have developed a framework for integrating Adaptive Windowing (ADWIN)
change detection algorithm with KDE. We have tested this approach on several real
world data sets and received positive feedback from our industry collaborator. Some
results appearing in this thesis have been presented at ECML PKDD 2015 Doctoral

abstract:
The focus of my research is vocal disguise within forensic linguistics. Specifically, I answer the
question of what individuals are most likely to do with their voice when they do not want to be
recognized by a listener. I also focus on whether specific sociolinguistic characteristics – gender
and place of origin – have an effect on the disguise choices that individuals make. My research
has found that participants show a preference for altering pitch and/or duration across conditions,
as well as taking on a foreign accent. Gender and origin were found to be significant for respect
to differences in duration, and significance was also found between origin and pitch. These
results suggest that disguise might contain elements of style shifting, and that a speaker's choice
is more systematic than random.

title: Parental attitudes of inclusion

abstract:
The purpose of this qualitative study was to develop an understanding of parents’ attitudes towards inclusion. This investigation focused on parental perspectives of inclusion based on their child’s receipt of educational services. Perceived implications of inclusion were relative to each participant; therefore, results could not be considered generalizable.
This study employed purposive sampling in acquiring participants. Eligibility for this study included being the parent/guardian of a child who received special education services in school. Semi-structured interviews were used to collect data, allowing participants to tell their story about their experiences with inclusion. Parents in this study were eager to share their attitudes towards inclusion, speaking candidly about their children’s successes attributed to inclusion as well as issues experienced. Parents identified a number of outcomes of inclusion, namely, social interaction, self-esteem, instructional support, and normalcy.
