abstract:
L’accès aux soins de santé est un enjeu au Canada, particulièrement dans les communautés
rurales et éloignées. Cette situation représente un double défi pour les francophones d’Iqaluit au
Nunavut : avoir accès à des soins et à des services de santé, mais aussi avoir accès à ces services
dans sa langue. Or, selon le concept de capital social, les réseaux de relations sociales permettent
d’avoir accès aux ressources nécessaires au développement des individus et des communautés.
À partir du modèle conceptuel Capital social dans les communautés francophones en
situation minoritaire, développé par Louise Bouchard et Anne Gilbert (2005), nous avons
procédé à une analyse thématique et à une analyse textométrique des discours que tiennent des
professionnels de la santé et des services sociaux et des gestionnaires francophones d’Iqaluit afin
de relever les facteurs qui entrent en jeu dans la construction de leur « capital social » et de mettre
au jour la dynamique qui anime cette communauté territoriale de langue officielle en situation minoritaire (CLOSM).
Les résultats révèlent que les réseaux sociaux qui se créent au sein de la communauté
francophone d’Iqaluit facilitent l’intégration des migrants francophones qui décident de venir
s’installer à Iqaluit. Ces réseaux sociaux, particulièrement développés chez les familles qui
comptent de jeunes enfants, offrent des moyens de briser l’isolement, tout en aidant les individus
à composer avec l’espace – tant géographique que temporel – qui façonne la vie à Iqaluit.
Malgré ses limites, cette étude ouvre la voie à d’autres recherches qui, à l’aide de données
sur la santé des francophones d’Iqaluit, permettraient de cerner l’incidence du capital social sur la
santé des individus, de la communauté ou des collectivités.

abstract:
The phenomenon of rockburst damage localization, which is not well understood, has been
observed in deep underground mines. Analysis of seismic wave propagation in underground
mines is of great interest for improved understanding of the dynamic rock failure problem. This
thesis aims at making a contribution for improving understanding of the seismic wave
propagation in deep underground mines. Advanced numerical modeling tools are used and new
modeling techniques are developed to attain this goal.
In this thesis, research is emphasized on the ground motion around excavations due to seismic
wave propagation that results from a fault-slip seismic event in the far-field and the near-field. It
is found that moment tensor point source model seems to be suitable for the source
representation in the far-field and the non-point source model (such as kinematic rupture source
model) seems to be suitable for the source representation in the near-field. The modeling results
confirm that ground motion is influenced by many factors such as target-source distance, slip direction, spatial location, and geometrical and geological conditions.
Influence of wavelength-to-excavation span (/D) ratio on the wavefield is investigated to gain
insights of ground motion behavior under both quasi-static and dynamic loading conditions. It is
revealed that PPV (peak particle velocity) values increase as the /D ratio increases and the
amplification effect increases as the /D ratio decreases. The loading condition maybe changed
from the dynamic loading to the quasi-static condition when the /D is larger than 30. Strong
dynamic loading should be considered when the /D ratio is small (less than 10, with a shear wavelength less than 50 m and an excavation span greater than 5 m) for most underground
excavations.
A method is proposed to estimate the quality factor (a measure of energy loss per oscillation
cycle) for shear waves propagating in underground hard rocks so as to gain insight into the
influence of internal attenuation on seismic wave propagation. A proper shear wave quality
factor can be obtained by comparing modeling results with that from a scaling law, even if there
are no high quality data for quality factor back analysis. Furthermore, the influence of different
geological structures on seismic wave propagation is studied. It is shown that wave propagation
patterns around an excavation can be altered and PPV amplification and shielding effect can
occur near the excavation boundaries amongst other reasons due to heterogeneities such as
tunnels, open and backfilled stopes, and dykes in underground mines. Finally, a coupled numerical procedure, which couples FLAC and SPECFEM2D, is developed to
consider the excavation effect on ground motion. The FLAC model considers the excavationinduced
stress change and rock mass failure, and passes the input data to SPECFEM2D by
invoking FISH scripts. In addition, a new nonlinear velocity model that considers the influence
of confinement and rock mass failure on wave velocity is presented. This nonlinear velocity
model and the coupled numerical technique are used to model a simple stope excavation problem.
It is found that there is a large difference in the wavefields and ground motions between the
results from the uniform and non-uniform velocity models. A relatively stronger amplification is
observed in the low confinement zones and on the excavation surface in the non-uniform
velocity models. Because stress redistribution and rock mass failure around an excavation are
considered, a realistic non-uniform velocity field can be obtained. The proposed coupled numerical procedure offers a method to improve the understanding of the site amplification
effect and ground motion near excavation boundaries.
This thesis presents some insights with regard to seismic wave propagation due to fault-slip
seismic events in underground mines. If seismic wave propagation in underground mines can be
modeled properly using techniques such as these presented in this thesis, then it is possible to
conduct forensic analysis after a large seismic event so as to explain one of many factors that
caused rockburst damage localization. Alternatively, the modeling approach may provide
valuable inputs for decision-making with regard to strengthening high risk areas to prevent
rockburst, thus improving mine safety.

abstract:
This thesis adhered to an integrated article format with two distinct studies focusing on
the analysis of patient medical records from a rural hospital in north east Ontario (Study
1) and a cross-sectional observational investigation of patient perspectives on community
paramedicine (CP) (Study 2). The aim of Study 1 was to help hospital administrators
identify patients at high risk of frequent hospital resource utilization (emergency
department (ED) visit or admissions) so that if appropriate, they may be redirected to
alternative services available in the community. Therefore, the two main research
questions for this study were: (1) Which types of patients are more prone to having repeat
ED visits and hospital admissions; and (2) What types of services could better serve or
help improve the health of these patients? Study 2 aimed to evaluate patient and caregiver
perspectives related to their involvement in three CP programs in rural communities
across Northern Ontario. There were two research questions guiding the evaluation of
patient perspectives in this study: (1) How effective is CP at supporting patient-centered
care; and (2) How do perceptions differ between home visit (HV) and wellness clinic
(WC) patients? In Study 1, twenty-six patients met the criteria for repeat ED visits (65%
female; mean age 52 years) and accounted for a total of 623 ED visits. Seventeen patients
met the criteria for repeat admissions (41.2% female; mean age 73 years) and accounted
for 69 repeat hospital admissions. The most common reason cited for repeat ED visits
was dressing changes and the most common reason cited for repeat admissions was
chronic obstructive pulmonary disease. For Study 2, 91.7% (n=55) of patients reported being satisfied with the CP services they received and 98.3% (n=59) of the patients
indicated that they would recommend CP to others. Patient perspectives of CP suggest
that the service model is consistent with a patient-centered framework that includes
interpersonal, psychosocial, clinical, and structural dimensions. The patients also valued
CP for the ease of access and the reassurance provided by the paramedics monitoring
their health concerns. Our studies found that an older population with increased health
needs appear acceptable towards receiving alternative health care services outside of the
hospital. Based on the perspectives of patients currently enrolled in CP programs across
Northern Ontario, the HV and WC services of CP appeared to be considered as an
acceptable program that can provide patient-centered care in rural and northern
communities. Collectively, these two studies provide important data related to the patient
experience in a rural and northern health care system context. These are encouraging
signs that alternative health care services, like the CP programs, can address non-urgent
issues for residents of northern and rural communities in Ontario.

Recognition

abstract:
The current study examined the relationship between the recognition of the six basic emotions as
a function of trait anxiety. Previous research has led to conflicting findings; one study reported
increased accuracy for expressions of fear, and another finding no differences as a function of
trait anxiety. As suggested by previous literature, the current study included eye movement
measures to further investigate the processing of emotional expressions in anxious individuals.
The current study also utilized four intensities of emotional expressions, a new addition to
anxiety literature, as well as incorporated a measure of emotional dysregulation. The task
consisted of a free viewing recognition task of expressions of the six basic emotions. Results
from the current study revealed no accuracy or viewing time differences as a function of trait
anxiety, however, a robust relationship was found between level of trait anxiety and emotional
dysregulation. Clinical implications and future directions are discussed.

Therapeutic benefits

abstract: Yelling has been used as a form of healing in Indigenous cultures (Nabigon, 2010). Research suggests benefits to therapies that incorporate yelling (Karle, Corriere, & Hart, 1973). However, the physiological impact of yelling has not been investigated. The current study explores EEG measurements of yelling as compared to its derivatives (deep breathing and a vocal control). Ten participants from Laurentian University were recruited. Results of relative spectral power analysis provide evidence of a significant increase in relative gamma power following the yelling condition only (F(14,98) = 2.87, p=.001, ŋ2=.291). POMS scores confirm that there was a significant total mood disturbance reduction following the yelling condition only (t(9)=3.68, p=.005). Findings support strategies designed to enhance health and well-being.

abstract:
Emotion comprehension has been shown to have numerous benefits, many of these being
in the areas of social and academic functioning. Emotion comprehension starts to develop
in early childhood and because of its many advantages, studies have used various
interventions to try and teach emotion comprehension skills to children of different ages.
The few interventions in the literature were complex, not readily accessible, lengthy or
required much training for administrators. Some of these studies also combined a variety
of different strategies and tools, making it unclear which specific components are
effective. The current study looked solely at the effectiveness of shared book reading
with picture books created based on current models of emotion comprehension. Fortyfive children were divided into control and experimental groups. Over the course of seven
exposures, results revealed significant gains in emotion comprehension for both groups,
with gains from children in the experimental group being slightly greater than those in the
control group. These results give promising insight, suggesting that a short intervention
such as this one could be effective in future studies with the combination of strategies
oby isolating different strategies and looking at their effectiveness.

Le taux de survie des nourrissons prématurés s’est amélioré de façon manifeste grâce à la formation des
soignants, à la régionalisation des soins prodigués au nourrisson prématuré et à une amélioration de la
technologie disponible aux professionnels de la santé. Malheureusement, malgré ces avancées, on a
observé peu de changement correspondant au taux de morbidité néonatale. Le suivi neurodéveloppemental
est un domaine de recherche important, surtout à la lumière de nouvelles preuves qui indiquent
que, jusqu’à l’âge de 6 ans, la croissance de la période prénatale est rapide, dramatique, et permet de
façonner les suivis à long terme de l’enfant. Dans ce domaine, aucune étude ne porte sur le développement
de l’enfant prématuré nord-ontarien. De plus, cette population est particulière parce qu’une proportion
significative est exposée à un environnement bilingue dans un contexte linguistique minoritaire. Cette
étude vise à 1) décrire les enfants nés prématurément et évalués par le Programme de suivi (PS) à l’hôpital
Horizon Santé-Nord; 2) comparer les résultats neurodéveloppementaux en langage des francophones aux
anglophones et 3) vérifier si certains facteurs biomédicaux et sociodémographiques permettent de
distinguer les enfants prématurés affichant un retard neurodéveloppemental des enfants prématurés qui se
développent de façon typique.

abstract:
The deposition and alteration of particulate matter (PM) in soils is a world-wide health concern.
This study investigates the fate of Copper in organic-rich surficial soil layers (0-5 cm)
contaminated by mining related activity at the Timmins Kidd Creek metallurgical site, Canada.
The sequestration and mobilization of Cu by organic material (OM) in the soil layer is investigated
using focused ion beam (FIB) technology and transmission electron microscopy (TEM). Copper
occurs as incidental metallic Cu and covellite (CuS) nanoparticles (NPs), formed via ion reduction
by humic substances and magnetite. Additionally, TEM analysis of the colloidal fraction, extracted
via ultracentrifugation from the surface soil layer, indicates the occurrence of incidental covellite
NPs in close association with dissolved OM. This study shows for the first time that Cu is
sequestered as incidental metallic Cu and covellite NPs within OM and magnetite in surficial
organic-rich soil layers. Furthermore, the mobility of Cu is facilitated through the transport of
covellite nanoparticles embedded within organic colloids.

abstract:
Black shale in the Little Dal Group (ca. <817 Ma), Mackenzie Mountains Supergroup
(<1005 Ma; >779 Ma), was deposited during the early Neoproterozoic, and is one of the
few known black shale deposits from this crucial time in Earth’s evolutionary history.
Relative iron enrichment (FeT/Al) and conventional iron speciation (DOP), along with
enrichment in molybdenum, total sulphur, and total organic carbon, were studied. Iron
systematics (FeT/Al >0.5 and DOP <0.80) indicate ferruginous, anoxic, and possibly oxic
bottom-water conditions over the time of deposition of the entire black shale unit. The
enrichment factors of several of the authigenic redox-sensitive trace elements (U, Mo, V)
are strongly correlated, and appear to be related to both the FeT and the organic carbon
content of the black shale. Molybdenum enrichment (<10 ppm) is limited, which is in
very good agreement with data from Mesoproterozoic black shales, but is much lower
than Mo enrichments in Paleozoic black shales (typically >100 ppm). Several black
muddy siltstones yielded similar results, but authigenic iron was greatly overwhelmed by
siliciclastic sedimentation. These new data support the theory that ocean bottom-waters
returned from sulphidic to ferruginous prior to development of oxygenated conditions in
the Ediacaran open ocean. This study documents a predominantly open-marine basin that
was characterised by ferruginous conditions, similar to Archean and early
Paleoproterozoic conditions, with brief intervals when oxic conditions developed.

abstract:
Does brain function irreversibly cease after death? Billions of years of evolution and hundreds of thousands of years of human development have inculcated within us an intuition that death is a deep pit from which thoughts and behaviour cannot emerge. This dissertation serves to challenge the assumption of neurofunctional loss after death by employing modern technology to observe alternative mechanisms by which information can be processed by fixed, post-mortem neural tissues. The central aim of the thesis was to measure periodic, electric potential differences (μV) characteristic of the psychological definition of “response” within neuroanatomical loci while the fixed tissues were exposed to patterned current, complex electromagnetic fields, chemical probes, and other experimental conditions. The findings presented here show that fixed post-mortem tissues express regional, electrical anisotropies which can be modulated by various applications of electrochemical energy and that the areas surrounding the hippocampus are most responsive. We show that neuropathology secondary to repeated and protracted seizure activity can be detected in post-mortem rat brains with coupled depressions of low-frequency signal periodicities. Our findings demonstrate that injections of current into coronal sections of fixed human brain tissue are most potent when patterned to simulate neuronal spike-trains and the dominant frequency of the equivalent living tissue subsection. We also show that fixed, post-mortem brain tissues act as electromagnetic filters, expressing signals non-randomly and preferentially within the right cerebral hemisphere. Further findings indicate that receptor agonist-antagonist probes (e.g., glutamate and ketamine) as well as other chemical applications can induce regional electrical responses as well as habituation-type phenomena over repeated exposure.
iv
These responses are paired and can be inversely related to photon emission from the tissue proper as inferred by photomultiplier tube measurements. The bases of the electrochemical responses are thought to be due to phenomena associated with pH and ionic gradients in general as inferred by our experiments with post-mortem rat brains. The aforementioned experimental results are then synthesized to produce a working hypothesis upon which further research can be based. We conclude that the brain’s structure-function relationship is sufficient to elicit post-mortem responses characteristic of a composite material of otherwise unknown potential.

abstract:
Recreational opportunities are valuable opportunities for physical, social, and emotional development. Summer camp provides youth with the chance to be outside among their peers and learn through play. Unfortunately, social, physical, and institutional barriers often result in the exclusion of high-needs individuals with neurobiological disorders from these camp opportunities and experiences. This research used a qualitative photovoice methodology in order to explore what summer camp means to adolescents with neurobiological disorders.
Teens aged 14-17 at Camp Neuro, a sleepaway summer camp in Ontario, were invited to take photographs of things that were meaningful to them (n=23) followed by an individual interview to contextualise the photographs (n=13). Results suggest that the physical, social, and emotional camp environments are important to youth with neurobiological disorders.
Additionally, the opportunity to learn at summer camp was a recurring theme as teens discussed learning skills, learning to make friends, and learning broad life lessons. Overall, the results suggest that youth with neurobiological are successful at summer camp and value their experiences when they are provided with appropriate accommodations and support. Ultimately, the participants expressed that Camp Neuro supported them to ha to be themselves, try new things, and make friends.

abstract:
Purpose: The purpose of this study was to examine the nature of the evidence addressing the fathering practices of men living with mental illness.
Method: A scoping review methodology, guided by the protocol of Arksey and O’Malley (2005), was used. Literature published between January 1, 2002 and December 31, 2012 was retrieved and 33 reports were extracted, aggregated and summarized.
Findings: Fathering practices were comprised of seven main topical categories: illness as impediment to fathering; non-illness impediments to fathering; father-mother relations; external informal and formal supports; availability of father to child; involvement of father with child; and, fathering for health, though rarely are fathering practices related to health outcomes.
Conclusions: The nature of the evidence reviewed illustrates the diversity of the current literature with little uniformity across the studies. Several gaps in research on fathers with mental illness continue to exist including research on paternal practices and associated health outcomes.

This thesis examines the work of Baroque architect
Francesco Borromini toward an architectural response to
the downsizing Catholic Church in North America. The
century following the Protestant Reformation offered
similar challenges to the Church. In response to the
Reformation, numerous Counter-Reformation measures
were employed to revive the Catholic Church. Architecture
that conveyed Catholic theology was considered a valuable
tool in restoring the Church. Selected buildings designed
by architect Francesco Borromini are examined for
insights into design techniques and strategies explored to
synthesize Catholic theology and architecture. The Sant’Ivo
alla Sapienza and San Carlo alle Quattro Fontane churches
in Rome are studied using research-creation methods that
employ architectural drawing as an investigative tool to
discover the theological significance of the buildings. The
architectural design proposal explores conclusions drawn
from research and applies the research findings toward
the design of small contemporary Catholic Church in

abstract:
The vast majority of children with cerebral palsy (CP) are surviving into adulthood due to
improved surgical and health care practice. Thus, the expiration of paediatric services means that
a new population of adults with CP has emerged that must transition into an ill-equipped adultoriented
system. Informed by the perspective of complexity theory, this case study used both
quantitative and qualitative data to examine the primary healthcare transition of youth with CP
living in Sault Ste. Marie, Ontario. Analysis of Ontario Health Insurance Program claims showed
service use changes due to both the expiration of paediatric services and the changing health
needs of individuals with CP as they age. Physicians commented on challenges due to the
complexity of the CP disease process and the benefits of shared care and teamwork in discussing
transition. Future research and clinical practice designed to address transition barriers need to be
informed by complexity theory.

abstract: The high incidence of Campylobacter jejuni-associated diarrhea, increase in the frequency of drug resistance in clinical isolates, and the recent association of C. jejuni infections and Guillain-Barré syndrome has heightened the need to develop effective anti-Campylobacter vaccines. Due to the risk of auto-immunity, vaccination using inactivated whole-cells or attenuated cells cannot be considered. Subunit vaccines however are a viable alternative and have been shown to be effective against similar pathogens. The main goal of this research is to test efficacy of the catalase A (KatA) protein as vaccine candidate against this pathogen. It was determined that KatA co-fractionates with both the soluble and insoluble cell fractions and a balanced IgG1/IgG2a response could be produced against it following immunization in mice. It was demonstrated that these antibodies can mediate complement-specific bactericidal activity and reduced adhesion and invasion of human epithelial (Caco-2) cells by C. jejuni using established in vitro assays.

My goals within this practicum were to enhance my social work practice skills by
facilitating motivational interviewing techniques during intake and crisis interventions, working
as part of multidisciplinary team, attending clinical supervision, and diligently critiquing my
social work practice with reflective MI log journals and a supervision journal. Throughout this
report, I reflect on the critical analysis of the practicum as I focus on two distinct observations
and insights within my MI experiences: 1) How can MI enhance treatment compliance? and 2)
What challenges might MI methods of interviewing present? Throughout the process of
completing this practicum and report, I reflected on the effective use of MI with the different
populations that presented, increased my MI skill set, and developed increased self-awareness through reflective social work practise.

abstract:
Three-dimensional reconstruction of small objects has been one of the most challenging problems over the last decade. Computer graphics researchers and photography professionals have been working on improving 3D reconstruction algorithms to fit the high demands of various real life applications.
In this thesis, we implemented a 3D scanner system based on fringe projection method. Two different methods have been implemented and used as the unwrapping solution in fringe projection method. A parameterization tool has been created in order to generate different fringe patterns for distinctive needs in the fringe projection method. Considering our first practical implementation (based on phase shifting and multi wavelength techniques) the number of pictures used in phase shifting method has been decreased and the effects of reducing the fringe patterns on the level of precision of the 3D model have been investigated. Optical arrangement and calibration of the system (fringe projection method) have been studied, and numerous suggestions have been proposed to improve the precision of the system. Also, an evaluation method has been implemented based on calibration techniques. The error rate on both surface and height of the 3D model compare with the object has been calculated.

This study investigated the relationship of wetland plant species with multi-season
roots (sMSR) and species with single-season roots (sSSR) to soil temperature across a climatic
growing season gradient. Study sites were in Lake Superior Provincial Park and Manitoulin
Island. In fall 2013, root ingrowth cores were installed in soil. Root length and shoot dry mass
were measured at harvests from spring 2014 to spring 2015. Results showed that soil and air
temperature differed by geographic zone; Lake Superior Provincial Park demonstrated lower
temperatures than Manitoulin Island. Soil temperature affected root length (positively) and shoot
dry mass (negatively). Root growth strategy had a nearly significant relationship with ratio of
spring to maximum shoot dry mass—greater for sMSR than sSSR; and a significant relationship
with relative late season shoot dry mass change—decreasing for sMSR and increasing for sSSR.

abstract:
Little is known about dementia informal caregivers’ experience with discharge planning,
and whether the discharge planning hospital team, including the physician, nurse
practitioner (NP), social worker (SW), and other allied health practitioners, meet the
needs of caregivers both in- and post-hospital. This interpretative phenomenological study
examines dementia informal caregivers’ experience with hospital discharge planning
post-discharge from an Ontario urban hospital. Five informal caregivers were interviewed
using semi-structured telephone interviews, and data was analyzed using Benner’s
interpretative analysis process (1985; 1994). Research findings suggest that dementia
informal caregivers consider their role as challenging due to many stressors and demands
and poor discharge planning. Informal caregivers reveal that information sharing and the
arrangement of community resources during the discharge planning process was
inconsistent. They felt abandoned and unsupported throughout the discharge plan, as
defined by lack of communication and dissemination of caregiver resources. As a result,
caregivers had difficulty understanding and managing their loved ones’ health care needs
after hospital discharge. Research findings can help inform discharge planning practices
and standards as it pertains to dementia informal caregivers.

abstract:
Interest in the expression of female aggression, antisocial behaviour, and psychopathy
has grown in recent years as a result of steadily increasing incarceration rates of women in
Canada (38.6% over the past 10 years). Previous research suggests that the relational nature of
female aggression, in offender and non-offender samples, differentiates women from their male
counterparts. Whereas males tend to be physically aggressive, relational aggression is the most
common form of aggression employed by women, is associated with psychopathic traits, and has
been found to predict criminal activity. As research pertaining to these factors in adult female
offenders is in its infancy, it is imperative that the role of relational aggression in incarcerated
women, both violent and non-violent, be further explored. To this end, a mixed method design
was implemented, including 56 female offenders recruited from three correctional facilities in Ontario, Canada. All participants completed a series of questionnaires measuring relational
aggression, antisocial behaviour, and psychopathy. Sixteen participants also participated in
semi-structured interviews querying their lived experiences of relational aggression in a custodial
setting. All participants, regardless of being identified as violent or non-violent offenders,
disclosed experiencing victimization by way of relational aggression while serving their sentence
and the majority acknowledged acting as perpetrators. Emerging from the results was a fivestage
descriptive model detailing the process through which dominant female inmates employ
relationally aggressive tactics (e.g., gossiping/rumour spreading, guilt induction, malicious
humour, social exclusion, and social manipulation) to establish and maintain social hierarchies
on their respective units. The presence of several psychopathic traits also emerged that prove useful in social hierarchy development; more specifically, both violent and non-violent women
exhibited a certain level of machiavellianism, callousness, social influence, rebelliousness, and impulsivity. Callousness, specifically, was found to significantly predict relational aggression
perpetration in those who also have more substantial histories of victimization by way of the
same relationally aggressive tactics. Additional results pertaining to female antisocial behaviour
and the observed psychopathic traits in the current sample are reported. Recommendations for
future research, training, and assessment are proposed.

The main goal of this study was to investigate the effects of manipulating product health
descriptions and serving size information on actual calorie consumption and estimations of calorie
consumption. In a 3 (no description vs. healthy description vs. unhealthy description) by 2 (normal
serving size information vs. larger serving size information) factorial design, 150 females over the
age of 18 years were invited to partake in a “taste test” of an oatmeal cookie product. In terms of
consumption, it was found that participants who received the larger serving size information
(labelled as 4 cookies/280 calories), which was double that of the normal serving size information
presented on traditional packaging (labelled as 2 cookies/140 calories), consumed significantly
less (M=139.92 calories, SD=98.88) than those who received the normal serving size information
(M=197.98 calories, SD=145.96). Participants therefore consumed approximately 29% less when
they were presented the larger serving size information compared to the normal serving size
information. When looking at overall accuracy of calorie estimations or how close their estimation
was to their actual consumption, it was found that those who received the larger serving size
information were significantly more accurate at estimating their actual calorie consumption
(M=57.42 calories, SD=73.97) than those who received the normal serving size information
(M=94.70 calories, SD=109.68). Furthermore, participants presented with a healthy product
description were significantly more likely to underestimate the amount of calories they consumed
during the experiment (M=-52.70 calories, SD=92.25) than those who received no product
description (M=-6.72 calories, SD=132.81) or an unhealthy product description (M=7.89 calories,
SD=127.14). Thus, product descriptions as well as serving size information can have a significant
impact on calorie consumption and an individual’s estimation of their perceived calorie intake.

abstract:
How connected are residents to the development of architecture in their respective
communities? This inquiry precipitates from the growing concern that the degree of
engagement between the greater public and the discipline of architecture is dismally
minute. At a local level, residents are left largely uninformed of the swift expansion
that often radically alters their surroundings. Architecture centres attempt to address
this divide by hosting a variety of programmes—such as lectures, exhibitions and
workshops—that enable those not versed in architectural discourse to question and
contest their built environment. Drawing from communication theory and the field of
graphic design, this thesis explores the architecture centre as a locus of community
engagement and participative debate fueled by information made accessible through
rigorous visual communication strategies.
From an in-depth study of architecture centres, globally and nationally, emerges five
distinct types of centres: the "institution", the "centre", the "hub", the "temporary" and
the "digital". Case studies of each type reveal that reanalysis of the operative functions
of architecture centres is necessary to envision even further salient methods of engaging
the public. This thesis argues that architecture can be made accessible by learning from
systems of communication employed by contemporary communication agencies and
graphic designers. Experimentation-through-making of print media such as zines and
posters assists in understanding how best to convey messages to the target audience.
The thesis posits that an architecture centre sited in a community that is projected to
see rapid, unprecedented growth will act as a proactive means of spurring a dialogue
between architects and residents to ensure all voices are being accounted for in their
prospective built environment. The design of an architecture centre further develops the
proposition that democratizing architectural ideas and planning processes can aid in
elevating the quality of future development in a community; and ultimately act as an
example of a single centre that would compromise a much larger network of analogous
centres working in tandem across Canada.

title: Exploring the explicit knowledge of the Duchenne marker and asymmetry in smile judgment

subject:
Authenticity of smiles
Explicit knowledge
Response options
Instructional effects

abstract:
Research has shown that individuals are sensitive to the activation of the orbicularis
oculi muscle (Duchenne marker) and are able to detect asymmetry. It has been proposed that
the differences in smile judgment performance might be explained by one’s explicit
knowledge regarding the morphological cues. The goal of the study was to explore
individuals’ explicit knowledge of the Duchenne marker and asymmetry in smile judgment
tasks. The present study also employed the Likert scale to examine the possible effect of
response options on smile judgment tasks. Participants also were asked to judge both the
happiness and authenticity of smiles. Three types of smiles (symmetrical Duchenne, non-
Duchenne and asymmetrical) were presented for the smile judgment task. Participants were
also asked to indicate if they noticed symmetrical differences and cues in certain facial
regions. Results showed that the symmetrical Duchenne smiles were judged as being the
most happy and authentic. This was followed by the non-Duchenne smiles while the
asymmetrical smiles were judged as being the least happy and authentic. This finding was
similar to that found in a previous study that employed the Likert scale, suggesting the
possible influence of response options on smile judgment. Similar results were obtained for
both the happiness and authenticity judgment conditions, implying that wording only had a
minor influence on smile judgment. Results also revealed that participants had good explicit
knowledge about the morphological cues but it was not perfect. Therefore, the results
suggested that explicit knowledge on its own is not sufficient to explain smile judgment
performance.

abstract:
Ce mémoire de maîtrise vise à explorer le concept d’identité professionnelle tel qu’il est rapporté
dans la plupart des écrits en travail social. Malgré le fait que l’identité professionnelle soit un thème
tout de même assez évoqué en travail social, il semblerait qu’à ce jour, le concept reste flou au plan
sémantique. En autres mots, il n’y ait pas de définition stabilisée de l’identité professionnelle en
travail social. La recherche sur ce thème reste pertinente, car plus les chercheurs étudient ce
concept, mieux ils arrivent à comprendre l’identité professionnelle, et par ricochet, la pratique
professionnelle et les travailleurs sociaux eux-mêmes.
Dans ce mémoire, nous nous intéresserons particulièrement au flou sémantique entourant le
concept d’identité professionnelle. L’objectif de cette étude est précis : il vise à explorer comment
les experts définissent l’identité professionnelle en travail social, mais aussi en enseignement1
.
Ce mémoire vise, enfin, à sensibiliser les lecteurs, et spécifiquement les travailleurs sociaux,
quant à la complexité du thème même de l’identité professionnelle, la réalité des multiples
définitions de l’identité professionnelle, ainsi que des enjeux reliés à l’identité professionnelle dans
l’exercice de la profession.

abstract:
The consequences of concussive injuries have been considered reversible, trivial, or
permanent depending upon the perspective of the professional and the precision of the
measurement tool. Saturated (daily) quantitative electroencephalographic (qEEG)
measurements for 7 days after a sports-related concussive injury and for 7 days about 8 months
later revealed conspicuous changes in power measurements in specific frequency bands over
the impact site as well as within specific, likely contrecoup, areas. The fluctuations with time
may accommodate the contradiction of results for concussive-EEG effects within the medical
and scientific literature. Normative qEEG profiles for 20 normal participants collected daily for 7
days indicated extraordinarily strong intra-individual consistencies in power metrics and suggest
that variability from easily established normative quantifications of topographic EEG activity
could differentially discern concussive effects. The concordance of shifts in mood states with the
power for relevant frequencies over expected regions of the cerebrum classically associated
with different moods supports the validity of the subjective experience-brain location coupling
and the direct contribution of subtle alterations in EEG power within certain frequency bands
and cerebral regions to the types of mood.

title: Factors contributing to the non-urgent use of the emergency department by Canadian triage and acuity scale IV and V patient in Sudbury, Ontario

subject:
Emergency department
Emergpatient perception
Canadian Triage and Acuity Scale (CTAS)
General System Theory

abstract:
In Canada, it is estimated that 57% of all emergency department (ED) visits are
for less-urgent or non-urgent care needs (Hodgins & Wuest, 2007). Factors that
contribute to the non-urgent use of ED services include lack of resources, insufficient
access to care, and lack of awareness regarding available health care options (Fieldston,
Alpern, Nadel, Shea & Alessandrini, 2012). The goal of this quantitative descriptive
design study was to determine the relationship between having access to a primary health
care provider, utilizing community based health care supports, and the patient’s
perception of illness, with the adult patient’s decisions for presenting to the ED with nonurgent
care needs.
Of the 119 respondents, 71.3% had access to a primary health care provider. A
majority of the respondents (70.1%) perceived the threat of their illness as moderate.
Those without registration with a primary care provider had a significantly higher
perceived threat of illness than those with a primary care provider. Results indicate that
72.6% of respondents presented to the ED because of a perceived urgency of need for
care, and 48.7% of participants came to the ED because they thought they required ED
services. Identifying why people present to the ED with non-urgent care needs can assist
health care providers and decision makers to enhance their understanding of the patient’s
expectations of health care services and their perception of illness.

abstract:
The following advanced practicum document reviews my social work practice experience
on both the In-Patient Psychogeriatric Unit as well as the Out-Patient Geriatric Behaviour
Response Team within Grey Bruce Health Services (GBHS) hospital in Owen Sound, Ontario.
Through the course of this practicum I was able to engage in various direct practice and
assessment opportunities within both a medical and community setting. Through these
opportunities I was able to engage in critical reflective practice and examine my use of self
within a therapeutic setting with older adults, living with dementia. A comprehensive literature
appraisal was conducted in order to demonstrate the rationale and increased need for working
with the older adult population. As well, it highlighted the role that critical reflection of self
plays within ethical social work practice, and details the positive and challenging nature in
engaging in this form of reflective practice.
This document goes on to detail various aspects of my advanced practicum experiences
and the opportunities I was afforded at GBHS. During my time with both the in-patient and outpatient teams, I was able to work within a multidisciplinary, medical team setting. This in turn,
provided complex and unique lenses in relation to my practice reflections and the various
dynamics of power between professional roles as well as with client and their families. Lastly
this document reflects on my own personal journey through the course of this advanced
practicum and how it in turn has enhanced my personal life, social work practice and clinical
assessment skills.

title: Visual art discourses as rhetoric: exploring the colonial creation of the Canadian Northwest Passage

subject:
Canadian landscape
art politics
Northwest Passage
internal colonization
cultural tourism
eco-tourism

abstract:
In the 1920s Canadian colonialism became domesticated; a political and
economic change was publically presented and mystified through the creation of a
professedly nationalist landscape mythology. In the words of A.Y. Jackson, Canada
needed “a new, modern landscape art tradition, for a new modern nation.”
According to Jonathan Bordo, such colonial myths of origins have served to supplant
aboriginal peoples by establishing a precolonial belief of “ terra nullius,” which was later
enforced by the removal of visual and cultural references to aboriginal cultures and
peoples, rendering their historic and contemporary presence invisible to colonizers.
In Canada, however, a second modern art tradition interceded. Even as the Group of
Seven’s interpretation of the Canadian landscape became definitive, Robert Flaherty’s
Nanook of the North rose to acclaim as well. Flaherty’s devotion to the idea (also borne
of Europe) that morally uncorrupted pre-modern landscape essentialist communities
existed in protective isolation would re-implant certain aboriginal peoples back into the
Canadian landscape imaginary, but on particularly disadvantageous terms.
Farley Mowat’s mid-Century reconfiguration of these two landscape art traditions as rhetoric continues to define Canadian understandings of the political relations
between aboriginal and non-aboriginal peoples, as well as the Canadian understanding
of political claims and relations between mainstream Canadians and their
government(s) and internally colonized peoples.
Since the closure of the two historic economic engines along the Northwest
Passage, sealing and the cod fishery, in the mid 1980’s and early 1990s respectively,
the turn to cultural and eco-tourism based economies has resulted in the wide promotion of images founded in Mowat’s reimagined history of Inuit and
Newfoundlanders. Cultural and eco-tourism have, in turn, led to a drive to conformity
with Mowat’s visions in Northwest Passage communities, which have resulted in both
processes of cultural selection, and instances of resistance.
As the Canadian administrative state positions itself with regard to melting
Northwest Passage, it behooves those wishing to understand the politics pertaining to
the Northwest Passage to analyze the rhetoric of the images underlying and
promulgated during these international negotiations.

subject: Aboriginal Health

subject: Cancer

subject: Indigenous Healing and Traditional Medicine

subject: Indigenous Methods

subject: Indigenous Knowledge

subject: Participatory Action Research

subject: Two-Eyed Seeing

abstract:
Cancer is a leading cause of death in Anishinaabe people and the incidence is increasing. Despite
reported successes of integrating Indigenous healing and Western medicine in the treatment of
addictions, domestic violence, mental health, palliative care and chronic illness, there is a paucity
of such information for cancer. A number of studies highlighted the need for awareness for
policy makers and physicians of the contribution of Indigenous healing to cancer care, as well as
the need for cultural safety.
This Indigenous inquiry examined potential benefits and challenges of including Indigenous
healing in cancer care. Using a participatory approach, I investigated how the cancer experience
was affected when Anishinaabe people included both Indigenous and Western medicine in
treatment and when they did not. This inquiry also examined how Indigenous healing assisted in
achieving Minobimaadiziwin, an Anishinaabe understanding of health.
Interviews were conducted with thirteen adults diagnosed with cancer from five Manitoulin First
Nation communities. Seventeen key informant interviews were conducted with those working
from Indigenous and Western health perspectives. A conversational method was employed in
this Indigenous research as it honoured the oral tradition of the Anishinaabe and was concerned
with co-creating knowledge in a relational context. Understanding stories involved Indigenous
knowledge and Western theory, framed as two-eyed seeing.
Participants recognized that Minobimaadiziwin could not be realized with Western medicine
alone. With the inclusion of IH/TM and recognition of the spiritual component of life, a person
can approach Minobimaadiziwin despite the obstacle of cancer along their path. This is best
iv
facilitated by braiding the two types of healing. Dissemination of results took two forms: a
collective, teaching story for the Anishinaabe people concerning cancer and Minobimaadiziwin
and publications concerning potential benefits of and challenges with pluralistic medicine for
Anishinaabe cancer care.

title: Application of seismic monitoring in caving mines

subject:
sublevel caving
mining-induced seismicity
caving mechanics

abstract:
Comprehensive and reliable seismic analysis techniques can aid in achieving successful inference of rockmass behaviour in different stages of the caving process. This case study is based on field data from Telfer sublevel caving mine in Western Australia. A seismic monitoring database was collected during cave progression and breaking into an open pit 550 m above the first caving lift.
Five seismic analyses were used for interpreting the seismic events. Interpretation of the seismic data identifies the main effects of the geological features on the rockmass behaviour and the cave evolution. Three spatial zones and four important time periods are defined through seismic data analysis.
This thesis also investigates correlations between the seismic event rate, the rate of the seismogenic zone migration, mucking rate, Apparent Stress History, Cumulative Apparent Volume rate and cave behaviour, in order to determine failure mechanisms that control cave evolution at Telfer Gold mine.

abstract:
The Kakula deposit is a high-grade sedimentary-rock-hosted Cu deposit (628 Mt, 2.72%
Cu indicated resource, 1% cut-off) ~10 km south of the Kamoa deposit (759 Mt, 2.57%
Cu indicated resource, 1% cut-off) in the central African copperbelt, Democratic
Republic of Congo. Copper-sulphide ore (chalcocite, bornite, chalcopyrite) at Kakula is
predominantly disseminated in the fine-grained matrix of clast-poor (≤20% clasts ≥2
mm) subaqueous debrite (diamictite), at the base of the nearly flat-lying midNeoproterozoic “grand conglomérat” (Mwale formation). Scanning electron microscopy
was used to document matrix texture and composition to develop a matrix paragenesis,
recorded in five phases of the matrix evolution: sedimentation, pre-ore diagenesis, mainore mineralisation, post-ore alteration, and weak tectonism. The ore-zone matrix is
porous, up to 12.5%, and consists of clay- to silt-sized muscovite, quartz, chlorite, Kfeldspar, dolomite, and biotite, whereas least-altered matrix, several hundred metres
above copper-sulphide mineralisation, consists of clay- to silt-sized quartz, albite,
chlorite, K-feldspar, calcite, and dolomite. Copper-sulphide precipitation is
contemporaneous with chlorite and biotite (+/- hematite, quartz, and K-feldspar) and fit in
a paragenetic sequence between diagenetic pyrite (± Fe-dolomite) and later muscovite.
Hematite is ore-stage and most abundant in areas containing chalcocite. Areas of mm- to
cm-scale “aligned” matrix (nearly vertical microfabric of aligned, elongated grains)
consists of a higher abundance of muscovite, locally elongated copper-sulphides, and a
lower concentration of copper than non-aligned matrix, suggesting that copper-sulphide
development pre-dated fabric development and that copper-sulphide grains were later dissolved and possibly remobilised. Although determining the original mineralogy and
texture of the diamictite matrix is challenging, the depositional matrix characteristics
(clast-rich versus clast-poor diamictite) and the availability of reactive agents (e.g.,
diagenetic pyrite) may have been important controls on copper grade and distribution.
More work is required to constrain the absolute timing of mineralisation, which is a
major debate at Kakula and Kamoa.

abstract:
The current document is a paper-based thesis investigating the lived experiences of parents
raising children with Fetal Alcohol Spectrum Disorder (FASD) in Ontario, Canada. Historically,
researchers have approached the exploration of families with the notion that families of children
with a developmental disability would present with a pathological profile. However, a recent
paradigm shift has transitioned the focus from deficit-based outcomes to those that highlight
positive outcomes. Therefore, the first paper included is a qualitative analysis of factors that
facilitate family adaptation. Interpretative phenomenological analysis (IPA) was used to analyze
semi-structured interviews with parents of children with FASD. Parents utilize a number of
coping strategies, supports, and transformational outcomes that enable them to adapt to raising
their child with FASD. The second paper included is also a qualitative analysis examining
demands that hinder family adaptation. Parents discussed five stressors that hinder successful
family adaptation. Recommendations from parents of children with FASD and implications for
increasing knowledge and awareness of the disability are discussed.

abstract:
With the development of and increased access to information and communication technologies a
new form of peer to peer aggression, cyberbullying, is on the rise. Research has only started to
skim the surface of this new form of bullying but, research has shown that there are numerous
negative outcomes associated with cyberbullying involvement whether it is as a cyberbully, a
cybervictim, both, or a witness. The current study investigated differences in aggression style,
interpersonal competence and school identification based on cyberbullying involvement as a
cyberbully, cybervictim, both or witness. As well the current study looked at how gender, age,
and grade related to cyberbullying involvement, and the impact of computer time, supervision,
and access to technology and location of home computers. One hundred twenty four students in
grades six through ten completed questionnaire packages, and there were significant differences
found in aggression style; cyberbully-victims had higher reactive aggression than cybervictims,
and interpersonal competence, specifically on asserting and conflict resolution subscales with
cyberbully-victims having lower competence scores than cybervictims. Significant results were
also found for access to technology. A correlational analysis was conducted to examine the
relationships between interpersonal competence, aggression, and school identification; numerous
significant results were found. As well an exploratory discriminant analysis was conducted to
determine if cyberbullying involvement could be predicted based on interpersonal competence,
aggression style, and school identification. Implications as they apply to research and
prevention are discussed.

abstract:
The experience and meaning of home for older, community dwelling women, was investigated.
In the world of gerontology there is a paucity of knowledge about those in their eighth and ninth
decade, and this becomes more pronounced among older women. With the older demographic
expanding and resources being directed at keeping seniors in their home- a solid knowledge base
is required. This study built on the knowledge that exists around home, aging at home, formal
care, and the vulnerabilities of aging in two ways. First, the literature around home was
synthesized with an evolutionary concept analysis which served to focus further research.
Secondly, an interpretive description study added to the knowledge of home by bringing to light
the precariousness of formal and informal care and the effect this precariousness has on the
meaning of home. The knowledge built in this study has the ability to inform policy,
organizations, education, and individual providers as well as highlighting areas for further
research.

les enfants d’âge préscolaire, les changements apportés à leur communication quotidienne (à la
maison, en garderie, avec les amis) à la suite d’interventions en orthophonie. Notre échantillon
comporte 35 répondants ayant des contacts fréquents avec des enfants de moins de 6 ans par
exemple des parents, des grands-parents et des voisins. Généralement, les répondants ont jugé les
phrases du FOCUS-F comme étant claires et le vocabulaire utilisé facile à comprendre. Quelques
énoncés ont été parfois identifiés comme étant plus difficiles à comprendre. La deuxième étude a
été effectuée auprès de 10 parents par le biais d’entrevues afin de mieux cerner les difficultés
encourues par les participants lors de la première étude. Cette deuxième étude a démontré que les
questions inversées du FOCUS-F s’avèrent plus difficiles à comprendre pour les parents. Elle
met aussi en lumière la présence de quelques questions pouvant être interprétées différemment
selon les parents.

abstract:
Athlete development can be described through transitions that mark turning phases
throughout athletes’ careers. Media data was utilized in this project to unpack the
career developments of two prominent world champion boxers from their early
lives to world championship status. Employing interpretive thematic analysis, five
themes were identified: (1) weathering hardships of early life (subthemes: the rough
life of an inner-city kid; abject poverty in war-torn Philippines), (2) entry into sport
(subthemes: groomed to fight; boxing to escape poverty), (3) amateur experience
(subthemes: Olympic medallist en route to the pros; struggling amateur with
dreams of greatness), (4) launching a professional career (impressive American
prospect; a charismatic unpolished slugger) and (5) capturing a world title
(subthemes: the much-anticipated world champion; the unexpected world
champion). This exploration augments our understanding of how two worldrenowned
boxers presented their career transitions to the world, with implications
for boxers and those who work with them.

subject:
Masking smiles
Enjoyment smiles
dimensional ratings

abstract:
Previous studies explored individual’s judgment of masking smiles using
dichotomous or categorical measures of rating which force individuals to categorize the
masking smile into one discrete category. The current study further examined
individuals’ ability to distinguish between enjoyment and masking smiles (smiles
containing trace of negative emotion) with positive-negative dimensional rating scales.
Thirty-two undergraduate students participated in the smile judgment study, which
consisted an Enjoyment smile and six masking smiles: a smile with a trace of fear, of
disgust, of anger in the brow, anger in the mouth, sadness in the brow and sadness in the
mouth. Participants had to evaluate each smile with four different scales, which contained
a positive and negative dimension (Happiness and either Fear, Sadness, Anger, and
Disgust).
Results indicated that participants could distinguish between the masking smiles
and enjoyment smiles as they rated the enjoyment smiles more positively than the
masking smiles. Participants were most sensitive to masking smiles containing traces of
fear as they rated this expression more negatively compared to the other masking smiles.
Other than the expression of anger (in the brow), masking smiles were rated more
negatively overall than the genuine enjoyment smiles. Finally, response rates were
quicker for enjoyment smiles than the masking smiles. Using dimensional measures of
rating in the smile judgment task did not change individuals’ judgment of the masking
smiles but may change the way the smiles are processed.

abstract:
This descriptive qualitative study examines how the ‘new vocationalism’ influenced the
historical evolution of credit transfer policies between college and university institutions
in Ontario. I used discourse analysis under the framework of interpretive policy analysis
in order to critically analyze documents reflecting college-university articulation policies
in Ontario, from 1962 to 2000. Interpretive policy analysis has been applied as a research
method to provide: a) a chronological overview of the data, and b) an analysis of the new
vocational discourse. Using a neo-Marxist lens, I investigate the larger political and
economic influences that have shaped postsecondary policies under the ‘new
vocationalism,’ including key concepts such as capitalism, hegemony, and alienation. I
assert that articulation agreements - influenced by new vocational discourses - were
deliberately implemented by the government of Ontario since the 1960s, in order to
reorient post-secondary education to the marketplace and fulfill the needs of the ‘new
knowledge economy.’

Eye-tracking

abstract:
Facial expressions of pain indicate that you are in need of attention. Previous studies have shown
that caregivers have difficulty distinguishing genuine, suppressed, and fake pain in children. The
current study examined parents’ and nurses’ ability to recognize pain expressions in children
while their eye-movements were tracked, to understand their accuracy and identify strategies to
improve. Results did not show differences between caregiver groups, however there was an
effect of expression type. Participants were more accurate for suppressed than genuine
expressions and more for genuine than fake expressions. Results from eye movement patterns
offer information on how to improve on recognition accuracy. For genuine and suppressed
expressions, participants must attend to the eye zone longer and faster to increase accuracy. For
fake expressions, the mouth zone needs more attention to increase accuracy, also the faster
participants looked at the mouth, the higher their accuracy for fake expressions.

abstract:
If the built environment can affect wellbeing, could a design approach that is centered around fostering reflective lifestyle habits in post-secondary student wellness centers improve the cultural perception of
spaces for mental health?In health, “mind and body dualism represents the metaphysical stance that mind and body are two distinct substances, each with a different essential nature.” 1 This frame of mind has distracted academic “focus away from the dynamic nature of human beings, [and] their relationship with the environment.”2 Contrary to mind-body dualism, this thesis argues that the built environment plays an intrinsic role in holistic wellbeing. Historically places for mental health have been about isolation away
from society, and there is still an element of stigma or shame that shrouds these spaces. Contemporary society is at the crux of a cultural shift which hopes to see mental health maintenance as a fundamental element of
holistic health. Architecture can mediate and promote this shift by providing spaces which, contrary to asylums
or psychiatric offi ces, empower those struggling with their mental wellbeing.3 Employing an approach called
the ‘measure-free recipe’ methodology, this thesis proposal endeavors to curate texture, path, context and
light; tactfully manage concepts of self, control, security and time; and architecturally manifest an environment
which would promote phenomenological experiences of empowerment, curiosity, comfort and decompression. Development of the ‘measure-free recipe’ derives from
a review of atmospheres which have negatively impacted cultural perception of holistic health, in comparison
to phenomenologically positive atmospheres. Details of this approach will be further articulated later in the
text. Importantly, the design of the Laurentian University Habitat for Holistic Healing and Wellbeing serves as the first ‘measure-free recipe’ taste test for growing spaces which foster ritualistic self-care.

abstract:
Tribotests are used to evaluate the performance of lubricants and surface treatments intended for
use in industrial applications. They are invaluable tools for lubricant development since many
lubricant parameters can be screened in the laboratory with only the best going on to production
trials. Friction force or coefficient of friction is often used as an indicator of lubricant performance with sudden increases in friction coefficient indicating failure through catastrophic adhesion. Under some conditions the identification of the point of failure can be a subjective process. This raises the question: Are there better methods for identifying lubricant failure due
to catastrophic adhesion that would be beneficial in the evaluation of lubricants? The hypothesis
of this research states that a combination of data from various sensors measuring the real-time response of a tribotest provides better detection of adhesive wear than the coefficient of friction alone.
In this investigation an industrial tribotester (the Twist Compression Test) was instrumented with a variety of sensors to record: vibrations along two axes, acoustic emissions, electrical resistance,
as well as transmitted torsional force and normal force. The signals were collected at 10 kHz for the duration of the tests. In the main study D2 tool steel annular specimens were tested on coldrolled sheet steel at 100 MPa contact pressure in flat sliding at 0.01 m/s. The effects of lubricant viscosity and lubricant chemistry on the adhesive properties of the surface were examined. Tests results were analyzed to establish the apparent point of failure based on the traditional friction
criteria. Extended tests of one condition were run to various points up to and after this point and
the results analyzed to correlate sensor data with the test specimen surfaces. Sensor data features were used to identify adhesive wear as a continuous process. In particular an increase “friction amplitude” related to a form of stick-slip was used as a key indicator of the occurrence of galling. The findings of this research forms a knowledge base for the development of a decision
support system (DSS) to identify lubricant failure based on industrial application requirements.

title: Image quality and dose of an accelerator-integrated kV CBCT systems

subject:
imaging modality
tumor
image-guided radiotherapy (IGRT)

abstract:
The ability of an imaging modality to precisely determine patient anatomy and provide
reliable information about tumor position is critical in the radiotherapy process.
As image-guided radiotherapy (IGRT) becomes more popular in radiation treatment,
its overall quality and performance, such as the image quality and amount of dose
delivered, need to be assessed. The research described in this dissertation was focused
on investigation of the image quality of the planar and cone-beam computed tomography
(CBCT) images of two imaging systems commonly used in radiotherapy: Varian
On-Board Imager (OBI) and Elekta X-ray Volumetric Imager (XVI). Several imaging
quality tests were performed using current clinical imaging protocols provided with
both systems and various types of image quality phantoms. CBCT imaging dose of
each system was also estimated using standard CT dose index (CTDI) phantoms and
several imaging protocols.
Overall, the image quality between the OBI and XVI was fairly consistent with
each other with the exception of high contrast resolution and Hounsfield Unit (HU)
accuracy. CTDI of OBI was higher than that of XVI which was related to the different
designs and imaging protocols between the two systems.

title: Building resilience and community capacity: the Sachigo Lake wilderness emergency response education initiative

subject:
Community-based participatory research
Rural and remote health
Health promotion
Indigenous health

abstract:
The Sachigo Lake Wilderness Emergency Response Education Initiative represented a
partnership between Sachigo Lake First Nation in northern Ontario Canada, and medical
professionals and university researchers from outside the community. This study was one
component of a larger community-based participatory research program to develop locally
relevant first response training to address the isolation from emergency healthcare in Sachigo
Lake. The aim of this qualitative study was to complete a formative evaluation to understand
how a five-day comprehensive training course implemented in May 2012: (a) met the local needs
of Sachigo Lake; and (b) fostered resilience and community capacity. The results of this study
describe the unique features of delivering first aid training in a remote context and illustrate the
intrapersonal and interpersonal impacts of the program. Health promotion through community based
first aid education is a model with potential to improve emergency care in the absence of
formal emergency medical services.

subject:
genetics-based diet analysis
Phacrocorax auritus

16S rRNA
DNA-barcoding

abstract:
The decline in Sander vitreus population on Lake Nipissing (LN) has become an
increasing cause for concern for the city of North Bay and the surrounding communities.
Double-crested cormorants (Phalacrocorax auritus) have been suggested as a possible
cause for the decline of these fish stocks. Using a combination of molecular and
bioinformatic techniques, I have developed a non-invasive genetics-based method for the
determination of Double-crested Cormorant (DCCO) diet using the 16S ribosomal RNA
gene. I observed general trends that were consistent over the overall two year-long study.
I observed small differences in diet dependant on the location of the island being studied,
as well as time of year. Overall, I was able to determine that DCCO consisted of the
following relative abundance of prey: 43% yellow perch (Perca flavescens), 27% troutperch
(Percopsis omniscomaycus), 12% pumpkinseed (Lepomis gibbosus), 7% walleye
(Sander vitreus), 4% rainbow smelt (Osmerus mordax), 4% unresolved, and 3% other
species. The data collected from this thesis can be applied to statistical modelling analysis
to possibly determine the impact DCCO have on the overall population of walleye, and
the methods could be applied for long-term monitoring of overall diet

title: Cognitive consequences of sleep deprivation, shift work, and heat exposure for underground miner

subject:
Sleep deprivation
shift work,

abstract: The extent to which an underground miner’s alertness is influenced by sleep deprivation, shift work, and working in elevated temperatures is currently unknown. Actigraphy and psychomotor vigilance data were collected from nineteen underground miners over 28 consecutive days. Core body temperature data was also gathered during four scheduled work shifts. Participants experienced shortened sleep durations and poor sleep efficiency throughout the study. Significant increases in reaction time occurred over the course of night shifts, a decline that was not observed during day shifts. A strong, negative correlation between core body temperature and reaction time was present throughout day shifts but did not appear during night shifts. Poor sleep and altered circadian rhythms appear to negatively affect the alertness of participants during work times. An inadequate adaptation to night work schedules may be indicated by the poor alertness and absent relationship between core body temperature and performance observed during night shifts.

title: Evaluation of a vibration measurement tool as part of a whole-body vibration management program in underground hard-rock mining

subject:
Whole-body vibration
iPod application
validation
knowledge

abstract:
Prolonged exposure to whole-body vibration (WBV) experienced by mobile equipment operators
requires routine measurement to manage the risk for numerous adverse health effects. The
WBVpod is an affordable and purportedly accurate iPod application that could provide workers
the means to regularly measure WBV exposure. The WBVpod was used simultaneously with a
gold-standard vibration meter to determine the level of agreement between the two devices
during laboratory and field trials. Furthermore, a pilot study that used the WBVpod and
educational sessions among underground miners (n=7) and trainees (n=11) was conducted to
determine how the WBVpod could compliment an intervention on perceived knowledge, as well
as gaining feedback from the participants on the usability of the WBVpod.
The WBVpod displayed a high level of agreement with the gold standard device for all three
axes (ICC: 0.92-0.97), with the vertical axis having the least bias (-0.015 m/s2) but a wider limits
of agreement (-0.136 – 0.106 m/s2). The pilot study found a significant improvement in
perceived WBV knowledge (U=9.5, p<.05), however discomfort was a common complaint when
sitting on the WBVpod for extended periods of time.
The findings suggest that the WBVpod would be a valid tool to estimate WBV exposure. In
addition, the majority of participants experienced an increase in perceived WBV knowledge and
increased ability to measure WBV

title: “What does this do?” The neoliberal creep, sexual health work and the deregulation of emergency contraception

subject:
Emergency contraception
women’s access
reproductive freedom
deregulation, feminism

abstract:
Beginning with eight women’s experiences in accessing emergency contraception from a
pharmacist, this research brings into view the undocumented “sexual health work” of obtaining
the drug in northern Ontario. Between 2005 and 2008, emergency contraception was deregulated
to behind-the-counter, forcing women to submit to mandatory counselling and screening about
sex, menstruation and contraception at the pharmacy. Situating unwanted pregnancy as harmful
in this context, an institutional ethnographic analysis explores the activities of health service
delivery and identifies the different ideological practices that shaped women’s access like the
steady creep of neoliberalism, professional specialization and clinical power. Ideological
discourses construct an ideal contraceptive user, who is patient, compliant and appears
“responsible”, contributing to the stigmatization of women. Findings suggest that an inaccurate
government definition of emergency contraception contributes to ignorance and misperceptions
about function; this, along with an empty federal policy vacuum for women’s health contributes
to its problematic status in women’s contraceptive options.

abstract: This thesis examined how variable the effects of changes in cSOD activity were on phenotypes across genetic backgrounds and between sexes. Analysis of variance (ANOVA), and the effect size partial eta squared (η2p) were used to partition the amount of variation attributable to sex, cSOD activity, and genetic background across the distal and proximal phenotypes assayed. The absence of cSOD activity results in pervasive changes in phenotypic expression, and these changes are only slightly modified by sex or genetic background. Higher levels of cSOD activity generally result in phenotypic expression closer to wild-type levels, though phenotypes were more susceptible to modification depending on sex and genetic background when some cSOD activity was present. Results here indicate that the cSOD-null syndrome is pervasive, and the significant influence of sex and genetic background across phenotypes supports the utilization of both sexes and multiple genetic backgrounds in genetic analyses.

title: Un nouveau modèle d’intervention de crise appliqué en contexte d’hébergement

subject:
centres de crise
psychiatrie
Québec

abstract:
Au Québec, l’intervention de crise est teintée d’un historique politique et institutionnel. Suite à la désinstitutionnalisation hospitalière, entreprise dans les années 1970, les centres de crise ont vu le jour au milieu des années 1980 dans un effort de désengorgement des urgences des hôpitaux offrant des services en psychiatrie. Presque 30 ans après la création des centres de crise, il importe de bien connaître l’intervention de crise et sa typologie, les bases de l’intervention ainsi que ses étapes, et le portrait de la clientèle qui utilise ces services, et les problématiques pour lesquelles ces personnes les consultent.
Par ailleurs, qu’en est-il des techniques d’intervention actuelles ? Se basent-elles encore et principalement sur le modèle d’intervention élaborée par le psychiatre Gerald Caplan et ses successeurs, une approche qui se veut cognitive et axée sur les capacités de résolution de problème des individus ? Selon les auteures Suzanne Larose et Marie Fondaire (2011), une dimension systémique doit être ajoutée à l’intervention en situation de crise. Elles ont donc élaboré un nouveau modèle qu’elles présentent dans leur livre intitulé : Détresse psychologique en situation de crise. Ainsi, au-delà du modèle classique, ces auteures présentent une perspective intéressante pour un stage spécialisé en intervention en situation de crise. C’est pourquoi nous avons choisi de l’utiliser et de présenter des études de cas en fonction de leurs critères.
Selon le type, la gravité et l’urgence de la crise, certaines personnes sont invitées à séjourner pendant quelque temps au sein des résidences thérapeutiques des centres de crise. À cet égard, comment décide-t-on de la durée optimale du séjour pour chacun des usagers afin d’assurer le rétablissement de cette personne, qu’elle ait retrouvé un équilibre et acquis des compétences d’adaptation lui permettant de faire face à des situations de crise futures ?
Voilà quelques questions que nous nous sommes posées sur la pratique de l’intervention en situation de crise et auxquelles cet essai de stage spécialisé cherche à répondre à l’aide d’une réflexion théorique basée sur le modèle de Suzanne Larose et Marie Fondaire (2011).

abstract: The purpose of this study was to manufacture a cover soil that will be suitable to create ‘cover islands’ of native boreal vegetation for reclamation of large mine rock piles generated through open-pit mining activities in the Boreal Shield region north of Lake Superior. Multiple Technosols were manufactured from blends of mill derived organic residuals and finely crushed mine rock. A ten week growth study assessing the performance of the Technosols as growth media for annual ryegrass demonstrated that blends of at least 50% woody residuals and a mixture of finely crushed mine rock could be used to produce a viable growth media. Reclamation plots were constructed in a field setting using two new Technosols manufactured in ratios of 40 and 80% organics using woody residuals and mixed mine rock, applied to 30 or 60 cm depths over a coarse mine rock pile to simulate ‘vegetation islands’. Soil microclimate data and soil pore-water samples collected over one annual cycle demonstrate that increasing organic matter increased soil moisture and concentration of bioavailable plant nutrients. Increasing depth of plots enabled development of a reservoir of available plant moisture below the rooting zone, but did not increase moisture in surface soils. Low survival rates of tickle grass and green alder can mostly likely be attributed to low moisture availability in the surface soils at the time of planting. Technosols composed of 80% woody residuals and deposited to a 60 cm depth could be appropriate for use in reclamation if surface moisture is increased.

Si les causes, les effets et les façons d’intervenir en contexte de souffrance au travail furent au coeur de la démarche d’apprentissage, ce sont les conditions qui favorisent ou non les bons retours au travail des employés qui se sont absentés pour une raison de santé mentale qui furent au centre de mes interventions individuelles et de petits groupes en service social.

subject: activité physique

abstract: Les taux d’obésité au Canada continuent à s’accroitre. Cette tendance est particulièrement inquiétante chez les adolescentes étant donné les conséquences médicales, sociales et psychologiques associées à l’obésité. Bien qu’il existe un nombre de traitements pour la perte de poids, l’impact de l’excès de consommation d’oxygène post-exercice (EPOC) sur le bilan énergétique n’a jamais été étudié auprès des adolescentes. L’objectif de cette étude est de déterminer l’effet de la durée, l’intensité et la dépense énergétique de l’exercice sur l’EPOC chez les adolescentes sédentaires. Huit adolescentes (15-17ans) ont complété 3 sessions expérimentales (30min à 61% du VO2max; 60min à 62% du VO2max; 36min à 76% du VO2max), suivies par 80 minutes de repos. L’EPOC n’a pas été influencé par la durée, l’intensité ou la dépense énergétique de l’exercice. Les adolescentes devraient donc être encouragées de participer à l’activité physique, peu importe les paramètres de l’exercice.

bubble growth dynamics
temperature perturbation method

abstract:
PICO is a direct dark matter search experiment that utilizes bubble chambers and the acoustics of
growing bubbles to discriminate signal from background events [5]. It has been shown that temperature perturbations from equilibrium significantly affect the growth of a bubble in superheated
water [17], particularly in the form of an onset delay to perceptible growth. In this thesis the temperature perturbation method is applied to superheated C3F8 to describe the acoustic background
discrimination achieved by the PICO experiment. We reproduced the delay in water and confirmed
its occurrence in C3F8. We hypothesized that the delay can be used for optical background discrimination. However, it was shown that the model does not apply to the energy deposition of different
types of particles as all of them, e.g. incoming alpha particles and neutron induced nuclear recoils,
create multiple bubbles along their tracks. Those bubbles, in the end, coalesce to form the observed
single visible bubble.

title: Application of advanced diagonalization methods to quantum spin systems.

subject:
quantum spin systems
matrix storage
Davidson and block Davidson method
Lanczos method
RMM-DIIS method
diagonalization

abstract: Quantum spin models play an important role in theoretical condensed matter physics and quantum information theory. One numerical technique that is frequently used in studies of quantum spin systems is exact diagonalization. In this approach, numerical methods are used to find the lowest eigenvalues and associated eigenvectors of the Hamilton matrix of the quantum system. The computational problem is thus to determine the lowest eigenpairs of an extremely large, sparse matrix. Although many sophisticated iterative techniques for the determination of a small number of lowest eigenpairs can be found in the literature, most exact diagonalization studies of quantum spin systems have employed the Lanczos algorithm. In contrast to this, other methods have been applied very successfully to the similar problem of electronic structure calculations. The well known VASP code for example uses a Block Davidson method as well as the residual-minimization - direct inversion of the iterative subspace algorithm (RMM-DIIS). The Davidson algorithm is closely related to the Lanczos method but usually needs less iterations. The RMM-DIIS method was originally proposed by Pulay and later modified by Wood and Zunger. The RMM-DIIS method is particularly interesting if more than one eigenpair is sought since it does not require orthogonalization of the trial vectors at each step. In this work I study the efficiency of the Lanczos, Block Davidson and RMM-DIIS method when applied to basic quantum spin models like the spin-1/2 Heisenberg chain, ladder and dimerized ladder. I have implemented all three methods and are currently applying the methods to the different models. In our presentation I will compare the three algorithms based on the number of iterations to achieve convergence, the required computational time. An Intel's Many-Integrated Core architecture with Intel Xeon Phi coprocessor 5110P integrates 60 cores with 4 hardware threads per core was used for RMM-DIIS method, the achieved parallel speedups were compared with those obtained on a conventional multi-core system.
