Transactivator of transcription protein
Macrophage polarization

abstract:
The human immunodeficiency virus (HIV) relies on its encoded proteins to
orchestrate cellular mechanisms for its replication and to induce inflammatory
responses that recruit and compromise lymphocytes. Among them is the HIV
trans-activator protein (Tat).  Tat is required for the viral replication and
enhances the infection of HIV in the host organism. Tat may also have an impact
on the functions of the macrophage, an important player in pathological changes
of AIDS patients.  Some evidence exists that may suggest a more M2 like behavior
of HIV infected macrophage.  Tat has been shown to down-regulate P53 in
macrophages.  HIV infected macrophage had higher amount of arginase and
became a major source of HIV viral load in patients with late stage AIDS.  In this
study, we investigated the possible role of Tat in the functional polarization of
macrophages, a process that switches macrophage function between pro-
inflammation (M1) and promotion of tissue repair and healing (M2).  Effects of Tat
on the macrophage were studied with human monocytic THP-1 cells that have
been stably transfected with wild type Tat, or N terminus segment of Tat 1-48 aa or C
terminus segment of Tat 37-86aa.  Lipopolysaccharide (LPS), an activator of M1
macrophage, was used to activate these THP-1 cells. Exposure to LPS led to
significant increase in inducible nitric oxide synthase (iNOS) in un-transfected
THP-1 cells, GFP transfected cells, and cells with Tat 37-86 aa.  However, THP-1 cells expressing wild type Tat or Tat 1-48aa showed no increase in iNOS whereas a rise in arginase was observed in Tat 1-48aa after LPS exposure. We also studied SOCS 1 and
SOCS 3 expression and observed a greater SOCS 1 induction only in clones that had
elevated iNOS in response to LPS. Wild-type Tat had no effect on SOCS 1
expression and cells with Tat1-48aa showed a decrease in SOCS 1. Cells expressing
Tat 1-48aa   displayed reduced HDAC 3 and SOCS 3 levels. Our data demonstrated
that wild type Tat and Tat 1-48aa may impair or diminish the response of THP-1
cells to LPS.  Our data may also suggest that wild- type Tat and Tat1-48aa have
conditioned THP-1 cells towards M2 polarization. This may also suggest that cells
expressing wild- type Tat or Tat 1-48aa may exhibit M2 behaviours.

La question de la santé mentale des adolescents de 14 à 18 ans fréquentant
l’école secondaire retient l’attention de plusieurs, dont les conseils scolaires, les
directions d’écoles, les professionnels, les parents et le grand public.
Mondialement, il a été reconnu par l’Organisation mondiale de la santé (OMS,
2014) que la première cause de maladie est la dépression tandis que le suicide
représente la troisième causant le décès pour les 10 à 19 ans. Quoique
préoccupantes, ces statistiques ne doivent pas pour autant faire ombrage aux
formidables potentiels de ces jeunes en considérant les nombreux changements
biopsychologiques auxquels ils sont confrontés.
La promotion et la prévention en santé mentale restent un levier des plus
importants pour favoriser le mieux-être des jeunes. À cet effet, un programme
d’intervention de petit groupe sur les compétences psychosociales auprès des
élèves de 10e année fut conçu conformément au programme ministériel Stratégie
ontarienne globale de santé mentale et de lutte contre les dépendances avec
son 3e objectif : repérer très tôt les problèmes en santé mentale et de
dépendance afin d’intervenir précocement.
Ce programme sur les compétences psychosociales a été créé pour une
clientèle adolescente ayant des problèmes d’estime de soi et de socialisation,
mais il peut être utilisé pour d’autres problématiques. En résumé, les
interventions sur les CPS ont démontré leur efficacité dans l’intervention de petit
groupe pour prévenir des troubles de comportements et de santé mentale,
d’adaptation, d’empowerment, d’isolement, d’estime de soi, de relations
interpersonnelles, de consommation, etc.

title: Expressive arts therapy in support groups for bereaved adults in a hospice setting

subject:
expressive arts therapies
EXAT
bereavement
support groups
social work

abstract:
Expressive Arts Therapies (EXAT) may be seen as a new practice but can be traced back
to the very beginnings of human existence and have been found on all continents and within most
cultures around the world. Since earliest recordings of man, art-making has been used to make
amends, rehabilitate, and transform a person in holistic ways affecting the physical, emotional,
mental, and spiritual aspects of a person leading to health and overall wellbeing. EXAT can
combine the visual arts, movement, drama, music, writing, and other creative processes to foster
deep personal growth and community development. EXAT can also be a guided spiritual journey
and process-oriented intervention with the role of the therapist as the guide into a safe space for
the client to experience integration of the arts. These approaches are convergent with social work
practice, which requires creative problem solving, whereby creativity is used effectively to shape,
mold, influence and uncover unrealized potential in clients. Expressive Arts Therapy also aligns
with social work practice in its theoretical underpinnings, stemming from humanistic, clientcentered perspectives. The advanced practicum described herein involved an 8-week Expressive
Arts course followed by facilitation of two bereavement support groups in hospice using
Expressive Arts Therapy. Some of the Expressive Arts themes explored during the 8-week course
and then implemented within bereavement support groups in hospice included: Introduction to
Expressive Arts; Exploring Relationships; Stories from the Field; Expressive Arts Modalities; Mindful Music and Movement in Expressive Arts; Planning Expressive Arts Experiences;
Professional Issues within Expressive Arts; Sand Tray; and Writing within Expressive Arts.
EXAT can be a very effective therapeutic approach in support of those grieving the death of a
loved one. With the knowledge, skills, and experience I have gained throughout this advanced
practicum, I will be able to confidently incorporate EXAT into my practice when working with
individuals, groups, and communities. Whether supporting bereaved individuals or facilitating bereavement groups, or holding memorial services in the community, EXAT is an effective
process legitimized by evidence-based research, supporting clients as they participate in the
creative process that can lead to positive change and emancipation. Expressive arts can be
integrated into social work as complementary or alternative forms of expression, therapy, and
healing aimed at individual and group change and among many populations in support of a wide
array of issues. In combining art and activism, social workers using expressive arts can draw
public attention to many issues of social concern. Expressive arts also have a place within social
work research, using modalities such as photovoice and performance inquiry.

title: The impact of summer break from school on children with severe autism and their parents: An Interdisciplinary Study

subject:
severe autism
autism education
summer break
regression
parent stress

abstract: The purpose of this research was to investigate the effect of summer break on the academic, social, life, communication, and behaviour skills of elementary children with severe autism and to assess the recoupment of skills in the fall. Regression and recoupment were measured by testing academic Individual Education Plan (IEP) goals based on the Assessment of Basic Language and Learning Skills (ABLLS) and the Vineland Adaptive Behaviour Scale (VABS) at four time points to assess a baseline in school, the effect of summer, and the effect of returning to school, and with parent interviews. The research found that students with severe autism regressed in academic skills over the summer break, but recouped those skills within four weeks of returning to school in the fall. The other areas, rated using the VABS, did not change either during the school year baseline or over the summer break, but according to parent interviews social skills decreased and maladaptive behaviours increased. The secondary purpose of this research was to study the impact of summer break on the stress of parents of children with severe autism and to gain a qualitative understanding of the impact of summer break. Stress was assessed using the Parent Stress Index (PSI) during the school year and then again during the summer and with parent interviews. The research showed that there were increased in parent stress during the summer break. Parents reported in the interviews that summer break also had an overall negative impact on child emotions, parent relief, the child's break from the parents, and the structure of the family day, and all of these, in addition to changes to skills and behaviours, contributed to parent stress. Summer break also had a negative impact on finances and siblings and some positive effects according to interviews. Parents saw their children's disability as primarily social, requiring interventions and supports from society, while also acknowledging impairment effects. Parents suggested quality, structured, funded relief programs and workers as a solution to the negative impacts of summer break.

abstract:
Gardnerella vaginalis is the etiological agent of bacterial vaginosis (BV), a chronic vaginal
infection that affects women globally. Increasing antibiotic resistance and failing treatment
options has resulted in chronic BV, demonstrating a need for novel alternative therapeutics. A
total of 34 environmental bacterial isolates with antimicrobial properties against a G. vaginalis
collection (n=17) were isolated and characterized for their antagonistic effects against G.
vaginalis isolates and for their production of antimicrobial active agents. The G. vaginalis
collection was shown to be diverse by genotyping and by their antibiotic susceptibility profiles.
Anti-G. vaginalis (αGV) isolates were identified and phylogenetically clustered following full
genome sequencing and their antiGV target range specificities were investigated. A subset of the
αGV collection (n=20) were shown to produce and export active antimicrobial agents with
molecular sizes of 4.6-35kD, which showed specific lethal effect on G. vaginalis isolates (target
ranges of 5-100%). Cocktail formulations consisted of promising representatives from αGV
clusters, with overlapping complimentary properties and specificity to G. vaginalis were
identified for further study as the antimicrobial candidates for BV.


title: Biomonitoring under changing climate conditions: assessing seasonal variability of benthic macroinvertebrate communities and stream characteristics in two ecozones in Northern Ontario, Canada.

Seasonal Variability

Ring of Fire
Biomonitoring
Climate Change

abstract: The vast “Ring of Fire” region, at the interface of the Boreal Shield and Hudson Plains ecozones in the far north of Ontario, Canada, is considered to be one of the most promising mineral exploration areas in Ontario in almost a century. The region is undeveloped and remote, accessible only by air, water or winter road. Multiple stresses to the natural ecosystems are anticipated with mining development, in a time of climate change which is predicted to significantly impact hydrological and temperature regimes (intensified spring freshet, more high discharge events, warmer temperatures for longer). Preserving and protecting the aquatic ecosystems in this pristine region will require effective baseline environmental monitoring in advance of development. Quantifying seasonal variation of habitat characteristics and benthic macroinvertebrate (BMI) communities, and assessing the seasonal difference between ecozones are considered key challenges in designing effective monitoring programs. In this study, I examined seasonal variability in habitat characteristics and BMI communities by sampling 43 stream sites distributed across the two ecozones. In 2015 each site was sampled three times during the open water season: post-freshet, mid-summer and fall. BMI communities varied among sampling seasons, but less variation was observed between the post-freshet and summer sampling periods than either of these compared to the fall. Ordination analyses of BMI communities identified to the family level indicated that sites from the same sampling season were more likely to group together. Water temperature, stream velocity and canopy coverage were the key factors associated with seasonal differences in benthic macroinvertebrates. Differences in location of the sampling sites across the two ecozones did not significantly impact seasonal variability, but differences may have been constrained by the common habitat features used because of the sampling protocol. Conducting sampling during the post-freshet or summer seasons is recommended for future stream bioassessments to reduce the influence of seasonal variability and thus ensure comparability over time.

title: Perinatal loss & infant custody loss : two unrecognized forms of loss during the perinatal period

subject:
perinatal loss
infant custody loss
bereavement interventions
social worker
women
families

abstract:
Perinatal loss and infant custody loss are two very different, yet in some ways similar loss events. The most dominant theme noted across the literature is that women and their families' experiences of perinatal loss and custody loss are socially under-acknowledged and inadequately supported by professionals. Another common thread is that both are historically oppressed experiences that uniquely impact the lives of women. The goal of this practicum report is to provide a synthesis of my learning and practice experience during my advanced practicum as it relates to providing supportive bereavement interventions to women and families who have suffered a perinatal loss or infant custody loss. Data sources for the development of this report
included several books; multidisciplinary and social work databases; government, social service agency, and non-profit organizations' websites; as well as my practicum experience. The practicum setting was the Paediatric and Obstetric departments, as well as the Neonatal Intensive Care Unit of Orillia Soldiers' Memorial Hospital. A discussion of the themes that emerged from my advanced practicum experience will help to demonstrate the advancement of my knowledge
and skill in working with loss and bereavement as it relates to the perinatal period. Social workers, especially those in hospital settings are in an ideal position to become actively involved in reaching out to women and their families after the loss of a baby. Thus, there is a call for feminist-minded social workers to bring awareness to the experience and service needs of women and their families who have suffered these unfortunate loss events.

title: The effects of learning on the eating responses of rats exposed to stress

subject:
stress
eating behaviour
operant conditioning

abstract: Literature examining the relationship between stress and eating behaviour reveals that while both decreased and increased eating are observed in response to stress, it is unclear what factors determine whether an individual will typically decrease or increase eating during stress. The present study sought to explore whether decreased/increased eating in response to future stressors, could be elicited by prior associations between decreased/increased eating and the presentation of a stressor, through operant conditioning. The “Conditioned Non-Eaters” (CNE) group received punishment training while the “Conditioned Eaters” (CE) group received negative reinforcement training in response to a noise stressor, and the Control group received no operant training. Conditioning trials were followed by a series of five tests exposing subjects to no stress, the noise stimulus, threat of shock, restraint, and a tail-pinch. Results indicate that group differences in eating were observed during exposure to the noise stimulus following training, but not in the absence of stress, and consistent group differences to the noise stress were further observed during exposure to novel stressors. These findings suggest that past operant associations between eating and a specific stressor can generalize to other stressors, influencing individuals to respond to stress exposure in a way that has be reinforced in the past.

subject:

emotion comprehension
shared book reading

abstract:
Previous studies have suggested that children’s emotion comprehension begins to develop in the
early stages of childhood and has been linked to prosocial behaviours, displays of empathy and
better interpersonal relationships, to name a few. However, children’s level of emotion
comprehension does not develop at the same rhythm due to both environmental and biological
factors. That said, there are few interventions that can help children in their development of
emotion understanding, but these interventions are not readily accessible (e.g., cost, availability,
duration). The current study examined the use of shared book reading and the effectiveness of
picture books created on current theories and models of children’s emotion comprehension.
Eighteen preschoolers were divided into an experimental and a control group. Over the course
of multiple exposures to the experimental treatment, results revealed a significant gain for the
experimental group compared to the control group. These results are promising by showing
that a simple shared book reading approach can contribute to the development of emotional
comprehension without requiring special training or expertise.

abstract:
Ontario FireRangers exhibit high annual injury rates and cite fatigue as a contributor, however
several factors influence fatigue, including: energy expenditure, energy intake, stress levels and
recovery time. The purpose of this research was to evaluate the accuracy of heart rate variability
(HRV) based estimates of energy expenditure (kilocalories) and to then assess energy balance,
physiological responses, and nutritional quality in Ontario FireRangers during different types of
fire deployments. Firstbeat Bodyguard2 and Zephyr BioHarness3 monitors were used to collect
HRV data, and individual audio-visual food logs were kept using an iPod Touch and analyzed in
NutriBase Pro11 software. Sleep quantity was also measured using actisleep monitors, to assist
with energy expenditure calculations. The findings of this research support the use of HRV
monitoring for free-living, energy expenditure estimation. Furthermore, this research indicates
that Ontario FireRangers exhibit high daily energy demands, under-consume kilocalories, deviate
from ideal nutrient consumption profiles and have varying levels of stress and recovery time,
depending on deployment type.

abstract:
Texting and driving has become a prevalent public health issue, especially in youth. The current
study recorded eye movements of young adults to texting and driving prevention advertisements
to determine the format that attracted the most attention. Thirty-three participants (Mean age 19)
viewed three types of advertisements (non-driving related, general distracted driving and texting
and driving specific) with three types of contents (text only, image only and text and image)
while their eye movements were recorded. Participants also completed a survey evaluating their
self-reported texting and driving behaviours. When comparing eye-tracking results for
participants who self-report texting and driving with those who do not, no significant differences
were observed. Results revealed an interaction of the types of advertisements and types of
content on dwell time. More precisely, when ads comprised text only, participants spent more
time viewing the texting and driving ads than the other types. For the texting and driving ads,
participants spent more time viewing when they comprised text only and, more time when they
comprised image only than both image and text. Regardless of the type of ads, when ads
comprised both text and image, participants spent more time viewing the images than the text.  Since viewing behaviour did vary whether participants text and drive or not, results do not
provide clues to produce more effective ads for the target audience. Nevertheless, results suggest
that in order to influence young adult’s attention to texting and driving prevention
advertisements, text-only display would be preferable.

abstract: The calibre of bullet used in the commission of crime is not typically ascertained from a wound in soft tissue, and cannot be reliably determined from the damage done to flat bones (1, 2). This study examined the feasibility of obtaining both bullet calibre and type from ballistic damage to long bones. Thirty fresh pork shoulders (Sus scrofa), in three groups of ten, were each shot with a handgun using one of three calibre. These calibres were of two bullet types, either lead or full copper jacket. Each pork shoulder was shot through the intact humerus with either a 0.22 round-nose lead bullet, 9mm full copper jacketed bullet, or a 0.38 round-nose lead bullet. The long bones were subsequently defleshed and examined for evidence of bullet calibre and type. The damaged bone was reconstructed to the fullest extent possible from the resulting bone fragments. The minimum diameter of each entrance wound, as well as the associated fracture pattern, were recorded. A Kruskal-Wallis nonparametric test was used to compare the median entrance wound measurements for each calibre. Cortical bone spalling was seen only In long bones shot with a copper jacketed bullet. This is due to the differing energy propagation of the two bullet types through the bone tissue. Our study demonstrates that bullet type can be ascertained from long bone damage, and the damage from a 0.22 calibre bullet can be distinguished from that of a 0.38 or a 9mm bullet.

abstract:
Mitigation of CO2 in industrial off-gasses by sparging the gas through photosynthetic
microalgae bioreactors is an attractive concept. The goal is for the CO2 to be consumed
by the microalgae as a nutrient, which in turn produces lipids suitable for conversion into
biodiesel, as well as other value-added bioproducts such as Omega-3 fatty acids and
antioxidants. Open systems are considered the most economic outdoor, large-scale cultivation option
but have large land space requirements due to their shallow depths (15-35 cm).
Consequently, finding sufficient space to locate them close to off-gas sources on
industrial sites can be a significant challenge. Shallow depths are also likely to result in
low uptake of CO2 and consequently reduced biomass productivity due to short gas
residence times in the culture medium. In order to obtain longer gas/liquid transfer times, as well as greater per area productivity,
the tanks through which the off-gas is sparged must be as deep as possible. However, to
make the tanks deeper and avoid the costs associated with sub-surface artificial lighting,
the issue is how to ensure the microalgae receive adequate light exposure. We have,
therefore, looked for a novel method for increasing the depth of the tanks through which
the off-gas is sparged. To achieve this, we have investigated the use of a gas-lift
circulating system in a deep top-lit open bioreactor. In addition to providing CO2, the
sparged gas also provides continual vertical circulation of the microalgae to ensure good
mixing and an adequate light/dark cycle. Compared to existing shallow open systems, the  results obtained showed comparable biomass productivity per unit volume, but
importantly around three-times higher biomass productivity per unit area occupied by the
bioreactor. The lipid productivity was also increased due to light and hydrodynamic
stresses. In order to enhance further light utilization efficiency in the deep cultivation bioreactor,
the use of a novel non-energy-consuming light column was also evaluated. The results of
using the light column showed a 33% increase in areal biomass productivity and a 16%
increase in areal lipid production. The proposed design and developed models can be easily translated into larger scale, onsite
production facilities in industrial sectors emitting off-gas. The carbon capturing
properties of microalgae can, therefore, help reduce industrial carbon dioxide emissions,
whilst at the same time producing biodiesel from the resulting lipids.

abstract:
Clostridium difficile infection (CDI) is the leading cause of nosocomial diarrhea worldwide.
Prevention and treatment of CDI requires an intimate understanding of the immune
response to the bacterium. Thus, this study investigated the plasma immune response of 79
patients at Health Sciences North in Sudbury, Ontario, Canada to identify immunodominant
C. difficile proteins. Plasma samples were obtained from patients diagnosed with C. difficile
infection, patients positive for C. difficile without symptoms, and patients who were
negative for C. difficile, with and without symptoms. The plasma samples were tested for
the presence of antibody reacting to C. difficile protein extracts using Western Blot analysis,
Wes immunoblotting, and subsequent characterization by 2-D immunoblot analysis and
mass spectrometry. Candidate immunodominant C. difficile proteins were found to be
enolase, acetyl-coA acetyltransferase, and the 50s ribosomal protein, L7/L12. However, the
presence and/or levels of antibodies that recognized these proteins in patient plasma were
not statistically different between patient cohorts. Further analysis of the potential immunogenicity of these proteins could be useful to CDI treatment and prevention

subject:

abstract: Human altered landscapes contribute to direct and indirect threats on wildlife populations. Chronically high stress, an indirect threat, has been associated with decreased fitness. I examined chronic stress in Midland Painted Turtles (Chrysemys picta marginata), Snapping Turtles (Chelydra serpentina), and Blanding's Turtles (Emydoidea blandingii) in areas with varying densities of anthropogenic structures in Muskoka,Ontario. Enzyme immunoassays were run, in partnership with Dr. Gabriela Mastromonaco (Toronto Zoo), on turtle claws to obtain concentrations of corticosterone (CORT). Most Snapping Turtles had above-minimum CORT, and male Midland Painted Turtles and Blanding's Turtles had relatively high CORT levels. Anthropogenic density did not seem to affect CORT levels, but more research needs to be done to understand the complex relationships. I also determined the rate and pattern of nest depredation, a direct threat, throughout egg incubation in areas of varying anthropogenic densities. Nest depredation occurred throughout egg incubation and relative nest mesopredator abundance did not differ among sites with varying anthropogenic densities. Contrary to some nest caging protocols, my findings suggest that nest cages should be kept on nests until the turtles hatch and priority should be given to caging nests in low road density areas to help increase population recruitment. Understanding indirect and direct threats to turtles can help inform mitigation strategies to improve their fitness.

subject:

abstract:
The abuse of alcohol is a fundamental component to consider when assessing the risk of
reoffending in sexual offenders. Previous research with sexual offenders has demonstrated that
being diagnosed with an alcohol use disorder almost doubles their chance of reoffending. While
there has been much research on alcoholism and sexual offenders, there remains a gap in
literature considering the impact of alcohol abuse and drug abuse with psychopathic sexual
offenders. A review article briefly indicated that elevated scores on the Michigan Alcohol
Screening Test (MAST) might moderate the Hare Psychopathy Checklist-Revised (PCL-R)
ability to predict recidivism. No, follow up study was discovered to observe further results. The
current study evaluated the impact of these findings using a long-term recidivism database
collected in the Ontario Region of Correction Service Canada (CSC). The database included over
500 high-risk sexual offenders from the Regional Treatment Center, Sex Offender Treatment
Program (RTCSOTP). The database contained information on men, over 18 years of age, who
had served at least two years in custody for a sexual offense. The PCL-R, MAST, and DAST
were utilized to measure psychopathy, alcohol abuse, and drug abuse, respectively. A Cox
regression analysis revealed that the PCL-R and the DAST were significant predictors of sexual
and violent recidivism, but the MAST was not a significant predictor of sexual and violent
recidivism. The MAST did not impact the PCL-R’s capability of predicting recidivism in a
moderate to high-risk sample, as previously observed. While the result of non-significant MAST
prediction was contrary to previous findings, these results indicate that targeting drug abuse
should continue to be a component in sexual offender treatment programs. Alcohol abuse cannot
be excluded definitively from the study of recidivism.

This project sought to explore identities used by leading competitor master level runners
in order for them to continue down the road of success. The following research question was
explored: How do leading competitor masters level long distance runners describe their life as a
runner, in relation to today, and the context they are training in? The participants were three
leading competitor master level athletes (age 50+), who all reside in Sudbury, Ontario. Artefacts
brought the project to a deeper level. An inductive thematic analysis was carried out. Themes
and sub-themes highlighted specific ways each masters’ athlete navigated their running journey
to allow them to maintain their competitiveness as a leading competitor. In conclusion, the study
discussed the importance of the athletic identity: how it functioned, shifted, and changed over
time to allow the athletes to navigate their other identities and go through processes such as
identity management.

abstract:
La question de la prostitution n’a rien de nouveau. C’est une question controversée souvent
au coeur de plusieurs débats. Le débat féministe entre les prohibitionnistes et les abolitionnistes en
est un qui situe la prostitution dans un espace de libération sexuelle ou, au contraire, comme une
domination des hommes sur les femmes. Le débat juridique sur la prostitution au Canada comme
ailleurs est aussi incertain quant à une acceptation commune de son application de principes.
Certains aspects de la légalisation de la prostitution apparaissent encore difficiles sur le plan des
rapports entre les sexes bien sûr, mais aussi sur la base d’une certaine hiérarchie entre les
travailleuses du sexe elles-mêmes. Le débat entourant la loi C-36 au Canada découle d’une mise en
cause de la constitutionnalité des restrictions qui existaient relativement aux travailleuses du sexe
qui n’avaient pas le droit de communiquer et de vivre des fruits de la prostitution tel que dénoncé
par le cas Bedford contre le Canada. Or, la loi C-36 « Loi sur la protection des collectivités et des
personnes victimes d'exploitation », en criminalisant le client et ceux qui profitent des fruits de la
prostitution, ne met pas fin aux violences et cela en particulier pour les travailleuses du sexe de la
rue. La nouvelle loi isole d’avantage celles qui sont isolées par manque d’information, celles qui
vivent en région et celles qui travaillent sur la rue. C’est là du moins ce que la présente thèse montre
à l’aide de témoignages de femmes, travailleuses du sexe de la rue du nord de l’Ontario (à Sudbury
et à North Bay). Notre analyse montre une dimension intersectionnelle de la situation de la
travailleuse du sexe de la rue qui veut que dans le nord de l’Ontario. Non seulement elles sont
moins informées, plus isolées et plus à risque d’être exposées à la violence de la rue et du milieu
prostitutionnel. Nous questionnons comment cette nouvelle loi influence la vie et la réalité de ces
femmes considérées parmi les plus marginalisées d’entre toutes et qui craignent, avec la loi C-36,
d’être plus criminalisées encore. Une troisième voie entre la pensée abolitionniste et
prohibitionniste s’impose donc pour répondre aux besoins de ces travailleuses du sexe de la rue.

abstract: For a number of years, pigs have been used in a variety of forensic disciplines as a research tool, such as in forensic anthropology. However, pigs have not been used as a research tool in forensic DNA analysis. The use of pig DNA is becoming common in different areas of forensic science such as wildlife management but the transition to forensic DNA research has not happened yet. This paper proposes that pig DNA can be used in a forensic setting for research purposes in a lab that also conducts case work. The methods followed for the development of an STR profile using a commercial multiplex kit for pigs are the same as the standard procedure in a forensic Human DNA laboratory. The validation showed that pig DNA can be analyzed with the equipment currently used for human samples and it does not cross contaminate human samples. These factors would help small labs conduct both research and casework within the same laboratory.


title: Seismic hazard evaluation using apparent stress ratio for mining-induced seismic events

subject:
Seismicity
Mining
Hazard
Apparent Stress

abstract:
This thesis investigates precursory trends in seismic data prior to the occurrence of large and
potentially damaging seismic events at Agnico Eagle’s LaRonde mine. A variety of sample
populations are selected to represent varying degrees of seismic hazard within a large area of
interest at LaRonde. The main factor considered for hazard assessment is the local stress
conditions within the rock mass, inferred from the apparent stress of seismic events.
An alternative means of analyzing apparent stress measurements using a relative ratio, referred to
as Apparent Stress Ratio (ASR), is presented. The use of a ratio eliminates the need for
thresholds values to define high and abnormal apparent stress. ASR values are analyzed in
reference to varying time frames, allowing for changes in stress conditions over time to be
considered. Hazard maps created using ASR and peak ASR values correspond well to areas of
elevated seismic hazard previously identified at LaRonde. For an area of interest at LaRonde,
ASR as an alarm tool possesses a success rate of 68% with a false alarm ratio of 2:1.

title: The impact of childhood obesity discourses on domestic and reproductive labour for single mothers in Northeastern Ontario : an institutional ethnographic study

subject:
childhood obesity
critical fat studies
institutional ethnography
mothering
domestic and reproductive labour
weight stigma

abstract:
Rationale: The term “healthy children” is often used to describe children whose weights are
within a socially acceptable range which conflates health with thinness, often completely
overlooking other aspects of health and employing body-stigmatizing language about children.
Research Questions:
1. How do single mothers who live in poverty in Northeastern Ontario define good health
for their children? What role do considerations of obesity play in their definition of good
health?
2. What are the implications of participants understanding of health on their domestic and
reproductive labour?
3. How are these experiences mediated by the families’ social location?
Theory: Institutional ethnography (IE) is a theory and a method. IE investigates the coordination
of ideologies that shape people’s experiences. Institutions made up primarily of government
bodies and medical experts shape how childhood obesity is discussed in schools, the media, and
in everyday life, impacting how we understand and speak about children’s bodies. This includes
the amount and types of work expected of parents (primarily mothers) as well as the implications
for bodies that do not meet the standard deemed acceptable in a particular time and place.
Method: The research participants were twenty women residing in Northeastern Ontario who self-identify as a single mother living in poverty. I used two methods of data collection:
interviews and guided tours of key areas impacting children’s health, such as grocery stores or
places children play.
Analysis: I analysed the interviews and the interactions between participants and their
environment using an institutional ethnographic approach to coding. The aim of the analysis is to link the everyday lived experiences of research participants to the ruling relations in which they
are shaped.
Results: Participants talked about children’s health in ways that were consistent with obesity
discourses. When I asked what the term healthy child meant to them, the first response was
usually ‘food’ followed by ‘physical activity’. Mothers described a great deal of work that went
into trying to make decisions that they felt were healthy. However, they also described many
barriers to providing the types of healthy foods and activities they would like to provide for their
children.

abstract:
This is a mixed-methods study investigating parental satisfaction and wait times as parents
inquire about an autism spectrum disorder diagnosis for their child in a Northern Ontario
community. Satisfaction and wait times of those diagnosed with an autism spectrum disorder
(ASD) by a single practitioner were compared to satisfaction and wait times of those
diagnosed by the multidisciplinary assessment team in the Sudbury/Manitoulin region (the
Autism Diagnostic Team; ADT). No significant differences were noted between groups on
satisfaction or wait times. However, ADT group received much more consistent service, with
less variation in wait times between clients, and more consistent provision of comprehensive
services prior to the diagnostic meeting. Points of interest are noted for practitioners
including increased wait times for parents of children with milder forms of ASD and for girls.
No differences in wait time or satisfaction were noted between language groups. Content
analysis of the qualitative interviews representing mainly single practitioners saw the
emergence of themes including difficulty activating the assessment process, concerns
regarding the wait, and appointment demands. The importance of professional expertise,
empathy, and respectful communication also emerged. Parents felt the experience was
deeply distressing and they often experienced abandonment following the diagnostic process.
Additionally, parents whose children did not receive a diagnosis often felt confusion about
what to do next. Reducing wait times, increasing professional expertise, completing
comprehensive assessments, and using truly interdisciplinary teams should continue to be the
focus of service improvements that may translate into improved satisfaction.

subject:
tailings

sulfur oxidizers

abstract:
Mining practices produce a substantial waste product in the form of tailings, a problematic
liability particularly in materials where iron and sulfur become oxidized leading to acid mine
drainage (AMD). Native microbial consortia in tailings sites accelerate this oxidation by a factor
of 106. The oxidative capabilities of these consortia can be harnessed to bioleach low-grade,
refractory metals from the waste materials while also allowing for the potential stabilization of
nuisance elements. This project explores the contributions of native microbes isolated from
sulfide tailings from two different climates: colder climate tailings around Sudbury, Ontario and
warmer climate arsenopyrite refractory gold tailings from Ecuador (ECT). The cold community
project encountered technical challenges as is summarized here as an appendix. This thesis
focuses primarily on the ECT community. The ECT tailings were enriched in medium ahead of
bioleaching trials and a metagenomic analysis was performed to identify key organisms
responsible for driving bioleaching. The main contributors to the ECT system at the order level
were Acidithiobacillales, Bacillales, Burkholderiales, Clostridiales, and Thermoplasmatales. The
dominant organisms representing these orders were found to have complementary genetic
systems that drive iron and sulfur oxidation. Understanding these key players will help optimize
the conditions that the ECT culture will be applied in using stirred-tank bioreactors and will
provide the baseline metagenomic information to help monitor the health of these organisms
throughout bioleaching campaigns.

abstract:
Cardiovascular disease (CVD) is the leading cause of death and disability among Canadian and
U.S. women. A majority of Canadian and U.S. women are unaware of their CVD risk profiles,
symptoms of acute cardiac events, and take inadequate action to lower their risk. There is limited
understanding regarding the meanings associated with Canadian and U.S. cardiovascular health
campaign messages and user interactivity with these messages on social media. Filling in this
knowledge gap contributes to understanding how women’s beliefs and behaviours are shaped by
prevalent mass media forums, which construct certain portrayals of women’s disease, risk, and
health-related identities. Within this doctoral dissertation, four studies were conducted in order to
explore the media’s role in the social construction of CVD meanings. In the first study, a metasynthesis
was conducted of primary research findings regarding qualitative analyses of mass
media narratives surrounding women’s CVD in Canada and the U.S. Key findings included two
critical, transcendental themes: 1) the medicalized culture of women’s CVD risk, and 2) the
feminization of cardiovascular healthism. The second study was an ethnographic content analysis
of the portrayals of women’s cardiovascular risk and health identities on Facebook page
narratives of the Heart and Stroke Foundation of Canada (HSFC). An overarching theme of
philanthropy as an act of women’s health promotion was identified and three sub-themes: 1) a
culture of consumerism for women’s health promotion, 2) the cardiovascular systems of women
as sites of fear and dependence, and 3) women’s CVD risk, acute events, and treatment as
shared, community experiences. The third study used critical discourse analysis to explore the
Facebook page of U.S. women’s cardiovascular health promotion agency Women’s Heart
Alliance to investigate the discourses through which women’s CVD was portrayed, and the
implications of these discourses on the construction of subject positions for related social agents.
iv
Women’s CVD was constructed within two central discourses: a discourse of achieving health
equity and a discourse of healthism. These discourses intersected to construct the subject
positions of altruistic fighters, health activists, and compliant patients and consumerists. The
fourth study comprised a critical discourse analysis of the HSFC More Moments campaign
meanings on Twitter for men and women. CVD risk was portrayed through a discourse of
tragedy and loss, and a discourse of life and health, which constructed the subject positions of
visionary leaders, selfless humanitarians, and successful survivors. Collectively, the findings of
these four studies build upon understandings of the media’s nuanced contributions to gendered
constructions of CVD meanings and risk.

title: Understanding educational caregivers accuracy in detecting facial expressions of pain in children: an eye-tracking study

subject:
facial expressions
pain
children
eye movement

abstract: Facial expressions of pain are important indicators that an individual needs attention from others. Previous studies have found that different caregiver groups have had difficulty in distinguishing genuine, suppressed and fake pain in children. The current study examines education professionals and their ability to recognize pain expressions in children while their eye-movements were tracked. Eye-tracking was used to understand their accuracy in detecting pain expressions, as well as identifying strategies to improve recognition. Results indicated that participants were more accurate for suppressed than fake expressions, and more for fake than genuine expressions. Results from eye movement patterns offer information on how to improve accuracy upon recognition. For genuine and suppressed expressions, participants must attend to the eye zone longer than the mouth zone. For fake expressions, the mouth zone needs more attention to increase accuracy. Also, when participants spent more time in the eye zone than the mouth zone, their levels of accuracy decreased.

abstract:
Background: Worldwide, childhood obesity rates are high and even higher among
Indigenous children. Childhood obesity is of concern as it can result in metabolic conditions.
Much has been written about the causes of obesity, usually focusing on individual behaviours,
but a gap exists in understanding the social determinants of obesity in Indigenous populations.
Methods: Survey data was collected from First Nations students in grades 6 to 8 through
a diet and health behavior survey. Measurements including height, weight and waist
circumference were taken. Focus groups with 33 caregivers were conducted to explore the
determinants of physical activity and nutrition.
Results: The prevalence of overweight/obesity in children was 65.8%. The prevalence central
obesity was 37.7%. There was a strong positive correlation between waist circumference (cm)
and BMI z scores (rs = 0.84, p>0). Daily physical activity (DPA) of 60 minutes per day was
associated with a BMI ≤85th percentile and a waist circumference ≤90th percentile. Girls
consumed 3.5 servings of fruits and vegetables and boys consumed 2.5 servings. Consuming
fruit juice was directly associated with central obesity. Normal weight was associated with
participation in at least four types of cultural activities.   Caregivers identified impediments to physical activity as financial, recreational
technology, safety concerns, and community activation. Changes in lifestyles, influenced by the
consequences of colonization, have resulted in reduced physical activity. Colonial policies result
in funding challenges for children’s recreation programs and a reliance on government develops.
Safety concerns stem from intergenerational trauma created by colonial policies.
Dietary decisions were influenced by the availability of fish and game, hunting and
fishing regulations, food insecurity and the proliferation of processed foods. Dietary decisions are influenced by the contamination of traditional territories, the marginalization of culture,
participation in the economy and issues of poverty.
Conclusions: Waist circumference is an effective indicator of obesity along with BMI
and should be used in public health screening of Indigenous children. Low fruit and vegetable
consumption is of concern as is the consumption of fruit juice. Protective factors against obesity
are 60 minutes of DPA and participation in at least four types of cultural activities. Colonialism
is a determinant of physical activity, nutrition, and obesity in this population.


title: Are all stereotypes created equal? Examining gender as a moderator of event-related potentials evoked during schema violation

subject:
Schema violation
Gender
Sexuality
Implicit Association Test

abstract: Schema violation has been shown to have an impact on cognition. Previous research using reading tasks has shown that the impact is not the same across male and female characters, and research has shown that men and women hold different view of schemas. The Implicit Association Test (IAT) has been used as a method to investigate schema violation, but no study has effectively investigated gender differences. Therefore, this study specifically investigates the factors of participant and character gender on schema violation during the IAT. Event-related potentials (ERPs) were used to investigate the cognitive impact of schema violation while participants completed gender and sexuality IATs. Significant effects were found for participant gender and character gender in several ERP components (N100, P200, N400, and LPP), but only for the gender-career IAT. This suggests that on a basic cognitive level ERP activity is influenced by gender.

abstract:
The purpose of this study was to understand the perspectives of paramedics regarding
community paramedicine (CP) and their quality of work life (QoWL) in Northern Ontario,
Canada. Paramedics from eight emergency medical services (EMS) were recruited to participate
in an online survey that was distributed to them via REDCap software. The survey contained
several CP-specific questions and the 23-Item Work-Related Quality of Life Scale. The findings
indicated that the vast majority of paramedics are in favour of CP, however repeated service
interruptions, a lack of training, and patient data tracking were identified as issues that should be
mitigated to ensure successful CP program development in the future. There was a statistically
significant relationship between paramedic participation in CP and QoWL. These findings have
implications for EMS employers and decision-makers related to the effectiveness of CP program
activities, and they provide emerging insight into the relationship between QoWL and CP in
Northern Ontario.

title: Design, construction and validation of internal organ phantoms for biomechanical testing

subject:
Internal organ phantoms
Construction
Biomechanical testing for the liver

abstract:
This thesis includes the development, construction and testing of internal organ
phantoms, with focus on the liver, for biomechanical testing. Phantoms have various
biomedical applications such as surgical simulations, minimally invasive surgery, soft
tissue characterization, diagnostic tools and instrumentation calibration. However, there
is little work present in literature regarding phantoms and the work that is currently
available does not account for the non-linear viscoelastic properties as well as the
Glisson’s capsule. In this work, three different phantoms are presented: a fluid-filled
phantom, a perfused phantom and a hydrogel-based liver phantom. A testing apparatus is
designed, built and used to measure the force-displacement data during the indentation of
the phantom.
The first phantom that is designed and constructed follows the basis of a fluid-filled
vessel. It is composed of a linear low-density polyethylene (LLDPE) bag filled with
different fluids namely: water, a 1:1 water/glycerine mixture and glycerine. The
phantoms are subjected to quasi-static loading as well as relaxation testing. The effect of
density and viscosity, its size, and confined and unconfined boundary conditions are
characterized.
The second phantom is designed to investigate the effects of hepatic macrocirculation on
the biomechanical properties of the liver. The phantom is made of two-part silicone
(Smooth-On, ECOFLEX 00-30), and contains a network of conduits to model the large
! iv!
blood vessels in the liver. A perfusion system that captures the general features of the
human hepatic circulation is used to help investigate the effects of the different flow
parameters such as pressure and flow rate on the biomechanical characteristics of the
liver. The perfusion system is designed to reproduce comparable pressures to the human
portal vein and hepatic artery.
The third phantom is made of two parts, a hydrogel inner layer with a LLDPE outer layer.
The idea behind this phantom is to represent the organ as accurately as possible by
accounting for the capsule that surrounds the organ as well as the biphasic (solid and
fluid) nature of the organ. A biphasic poroviscoelastic model is used to model the
hydrogel while the LLDPE uses a non-linear hyperelastic and viscoelastic model.
Modeling is done in ABAQUS to fit the experimental data obtained from quasi-static
indentation and relaxation testing using a parametric study.
In conclusion, phantoms replicating the non-linear viscoelastic properties observed in
organs are presented and characterized.
Main Thesis Contributions
• Development and characterization of a simple fluid-filled phantom to represent
the mechanical properties of the liver
• Development and characterization of hydrogel-based liver phantom with
representation of the biphasic nature of the organ and the Glisson’s capsule.

subject:
Boreal wetlands
dissolved organic matter
drought
trace metals
biotic ligand modelling
toxicity.

abstract:
Wetlands are prevalent in the boreal shield, and are efficient at retaining metals and thus modifying the chemistry of downstream receiving waters. The Sudbury region of Ontario, Canada has suffered over a century of elevated metal and sulphur deposition from mining and smelting activity, and wetlands in the area have provided an important ecosystem service by adsorbing large concentrations of metals over decades of emissions. However, metals can be released from peat in some circumstances such as during dry periods that result in a drop in water table height. With emissions declines in the region, there is the potential that wetlands have remained contaminated and are now acting as a source of metals at annual scales. Stream metal concentrations and dissolved organic matter (DOM) exports were evaluated in six Sudbury wetland-draining streams to address the question: Are wetlands in mining-impacted watersheds releasing potentially toxic metals to receiving waters? Water table declines occured in response to summer droughts, and some metals (Al, Co, Cu, Fe, Mn, Ni, and Zn) were released during rewetting events. Other metals that have a high affinity for DOM (Cu, Al, Fe) were also released from some wetlands in the summer in response to mineralization and DOM release. Concentrations in streams exceeded provincial guidelines and fluxes of some metals (e.g. Ni, Co) exceeded atmospheric deposition inputs to lakes by as much as 12 times. Changes in DOM concentration and composition occurred concurrently with the mobilization of metals after drought, with large decreases in aromaticity (SAC340) coupled with decreased DOC concentration. Biotic ligand modelling indicated that these drought-related DOM changes had a large effect on Cu toxicity, and while predicted Ni toxicity increased because of drought-related increases in Ni concentrations, predicted Cu toxicity increased primarily because of drought-related DOM changes. It is likely that these metal stores will take a very long time to deplete,
iv
and this offers important insight into the recovery trajectory of aquatic communities in watersheds affected by smelting. The results can be used to advance restoration efforts in the Sudbury region and other similar smelter-impacted areas affected by aerial depositon of metals.

abstract: Soybean (Glycine max) is an important crop in the world in terms of total production and usage. It is also among the least diverse species. The main objectives of the present study were 1) to determine differences between ISSR and RAPD marker systems in detecting genetic variation in soybeans and 2) to identify and characterize accession- diagnostic molecular markers in G. max accessions. Genomic DNAs from 108 G. max accessions from 11 different gene pools were analyzed using several ISSR and RAPD primers. The levels of polymorphic loci detected with the two marker systems were in general moderate and similar.. Overall, 82% of genetic distance values were above 0.40 based on ISSR analysis. However, RAPD data revealed that the accessions from different countries are closely related with 64% genetic distance values below 0.40. The dendrograms constructed with ISSR data revealed that the South Korean accessions formed an out-group while the RAPD analysis showed that accessions from Sweden were separate from the other 10 gene pools. One variety-diagnostic marker generated with ISSR 5 primer was identified in the accession Kao Chien Tao from China. This marker was cloned, and sequenced. Although RAPD and ISSR marker systems detected similar levels of genetic variability, they target different regions of the soybean genome, resulting in different clustering of the 11 gene pools indicating different genetic relatedness among them. This finding demonstrates the usefulness of both marker systems in assessing diversity and relatedness among Glycine max gene pools.

abstract: Le sourire peut être une stratégie puissante pour dissimuler l’expression d’émotions négatives. On doit activer les muscles associés au sourire et simultanément inhiber des émotions négatives. Les études ont démontré que les adultes ne réussissent pas toujours à les inhiber, ce qui mène à des micros expressions, et que leur niveau de performance est près du hasard lorsqu’ils doivent différencier des sourires de joie et de masquage. La présente étude a examiné l’influence que les instructions et le choix de réponses pouvaient avoir sur le jugement des sourires de joie et de masquage comprenant des traces de colère, tristesse, dégout et de peur, utilisant une échelle Likert à 7 points. Les résultats démontrent que les participants ont jugé les sourires marginalement plus joyeux qu’authentiques, dont ceux de joie les plus joyeux, et ceux avec traces de peur les moins joyeux, ce qui correspond aux résultats obtenus lorsqu’on utilise un choix dichotomique. En somme, les résultats supportent l’importance des instructions données aux participants dans le jugement des sourires de joie et de masquage, plus que les choix de réponses.


title: Identifying return to work predictors among individuals obtaining psychological services

subject:
Mental health problems
absent from work
return to work

abstract:
Mental health problems have incapacitating effects on an individual’s capacity to hold
and maintain employment. Over half a million Canadians are absent from work due to
mental health problems every day, which costs Canadian companies an estimated 14% of
their net annual profit. Individuals who miss work for mental health reasons often
experience longer periods of absence, and return to work at a much lower rate than
individuals absent for other reasons (e.g., physical injury). Regrettably, empirically
based return to work interventions focused on mental health problems are lacking, likely
the product of a lack of consensus surrounding salient predictors of return to work. The
current study sought to add to current literature aimed at identifying factors that influence
the likelihood of successful re-entry into the workforce. A review of patient files from a private psychological practice yielded the sample.
Clients were selected based on their satisfaction of one central criterion: having
experienced a workplace absence and suffered from a mood or anxiety disorder as
classified by the DSM-IV-TR. Recruitment letters and consent forms were mailed to 74
eligible participants, for a response rate of 68% (n=50). The sample was predominantly
female (n=38 or 76%). Of the 50 participants, 27 successfully reintegrated to the
workforce (RTW=54%), following a mean absence of 13 months (SD=7.37). Emerging
from the results are higher risk categories (e.g., physically injured workers, low
educational requirements, disability providers) of reduced likelihood of successful return
to work. The role of symptom severity and availability of social support is also discussed
along with best practice implications for stakeholder/practitioners.

title: Exploring the relationships among nursing students' anxiety in the clinical setting and select demographics.

subject: Anxiety Nursing Students Age Gender Employment Education

abstract:
The clinical learning experience is an essential part of nursing education that is often
anxiety provoking. Understanding the factors associated with the anxiety levels of nursing
students in clinical placements has become more complex over the years with the increasing
heterogeneity of the nursing population. Associations between student demographics and their
anxiety levels in the clinical setting have not yet been explored in the research literature. The
questions guiding this descriptive correlational study are as follows: What is the anxiety level of
students as determined by the State-Trait Anxiety Inventory (STAI)? Is there a relationship
between students’ age, gender, previous employment, and previous education and their selfperceived
anxiety levels? The framework for this study is situated cognition theory.
The data provided through the study revealed that nursing students have a higher than
average level of anxiety. The data revealed no statistical significant correlations involving age,
previous education, previous employment, and self-perceived anxiety levels. There was a
statistically significant difference between the anxiety scores of the female group and those of the male group, with males reporting higher levels of anxiety. The data provide an opportunity
for discussion and identify the need for future research and practice.

abstract: This study examined the experiences of parents who enrolled their children in the English or French immersion program. Participants included parents of children in junior kindergarten, senior kindergarten and Grade 2. The primary method of data collection was parental interview. Questionnaires were also administered to parents with children in Grade 2. The results indicated that parents have different considerations when deciding to enroll their children in French immersion or English. Among parents with children in French immersion there was a trend of differential literacy practices and self-efficacy regarding homework support based on parental comfort in using the French language. Overall, the results indicate that parents desire more ease of access to information pertaining to enrollment and French immersion parents desire more easily accessible resources to support their children in homework.

abstract:
Reliable species identification methods are important for industrial environmental monitoring
programs. Probe based real-time PCR (qPCR) provides an accurate, cost-effective and high-throughput
method for species identification. Here we present the development and validation of species-specific
primers and probe for the identification of eight freshwater fish species. The development of a fully
automated species-decoder algorithm allowed for target species identification with 100% accuracy while
completely removing any false-positive detection of non-target species. Furthermore, the probe-based
qPCR technique utilized in this study is substantially more cost-effective and time efficient than DNA
barcoding and morphological identification methods. The qPCR assays were also highly sensitive and
accurately detected target species from collected environmental DNA (eDNA) samples. In summary,
probe-based multiplex qPCR assays provide a rapid and accurate method for freshwater fish species
identification and the methodology established in this study can be utilized for various other species
identification initiatives.

subject:
root lifespan

functional traits

abstract:
Perennial herbaceous monocots in Northern Ontario wetlands can be classified in two
distinct types of root turnover strategies: those with overwintering roots, and those with
complete root mortality at the end of the growing season. All species have autumnsenescing
leaves. The present thesis is part of investigations to understand adaptive
advantages of the two strategy types, focusing on nutrient remobilization from senescing
roots. Existing data on nutrient remobilization from senescing roots is based on changes
in element content in dying roots, and do not differentiate between remobilization and
leaching out. Root protein content and aminopeptidase activity was assessed for gardengrown
plants of six species from September to November, three species with autumnsenescing
roots (Rhynchospora alba, Sagittaria latifolia, Sparganium americanum) and
three with overwintering roots (Carex oligosperma, Iris versicolor, Scirpus microcarpus). We hypothesized that protein degradation and protease activity would be higher in
autumn-senescing roots. The results confirm the existence of two root turnover strategies,
species with annual roots showing a decline in root protein content, while species with
perennial roots did not show such a decrease. Leaf protein content deceased in all species
but C. oligosperma, known to senesce late. Total root aminopeptidase activity per fresh
mass decreased in species with annual roots, but not in those with perennial roots. In
contrast to expectation, specific aminopeptidase activity did not change over time and did
not differ between the strategies. We conclude that nitrogen remobilization is an active
process in senescing roots, and in autumn occurs only in annual roots. However, temporal
characterization of root enzyme activities requires more detailed investigations

abstract: The Pirquitas mine, located in the highly elevated Puna plateau region of NW Argentina hosts Ag-rich polymetallic mineralization that defines the southern limit of the prolific Andean Tin Belt. Approximately 500 m north of its currently active open pit is the Cortaderas Zone which hosts the large Ag-Zn-rich Cortaderas Breccia whose nature and origin were previously unknown. This thesis serves as the first academic study of the Cortaderas Zone that incorporates data pertaining to its geological setting, metal distributions, breccia bodies, mineralogy, ore textures, alteration and fluid inclusions to interpret the origin of its mineralization. The results of this study suggest that the Cortaderas Zone represents the high-level and distal expression of the richly endowed hydrothermal system once present at the Pirquitas mine. Its mineralization formed in a dynamic intermediate-sulfidation epithermal system where ore formation was facilitated by transient fluctuations in confining pressure that were caused by cyclical opening and closing of the system. These insights into the formation of the Cortaderas Zone have implications for understanding the formation and subsequent modification of ores in epithermal settings globally.

The present study examined the hypothesis that self-regulation of attention would
be the core mechanism that ties together two dominant conceptualizations of
mindfulness: (1) an eastern style more associated with influential figures such as Dr. Jon
Kabat-Zinn, and (2) a western style pioneered by Dr. Ellen Langer. Dispositional
mindfulness (defined as a trait rather than a momentary state of being) of eastern and
western styles as well as self-regulation were measured using self-reported
questionnaires: FFMQ, LMS and SRS. A large sample of participants (N=208), mostly
female university non-meditator students, completed the respective scales online. Selfregulation
of attention was correlated with both kinds of dispositional mindfulness. A
partial mediation effect of self-regulation of attention on eastern and western mindfulness
mode was revealed using the regression- based methods described by Baron and Kenny
(1986) and the Sobel-Goodman analyses. Implications and areas of future research are

title: Understanding the characteristics that contributed to Québec athletes’ olympic successes moving into, during, and out of the Olympic Games

subject:
Olympic Games
elite Québec athletes
Olympic meta-transition
media data

abstract:
The current study examined the characteristics that influenced four of the most successful
Québec athletes’ performances moving in, during, and out of the Olympic Games. Their
experiences were explored using media data (i.e., newspapers articles from the province of
Québec) through an inductive thematic analysis. Seven main practical conclusions were created
from this study with the first five relating to the three meta-transitions explored, and the last two
relating to limitations created by the the methodology used in the study. The conclusions are: 1)
Developing an empowering coach-athlete relationship in order to facilitate the athletes’
performances, 2) Starting a competition easy to finish strong, 3) Creating realistic but
challenging goals for every step of the Olympic season, 4) Consciously learning form success
and failures/mistakes, 5) Using mainly intrinsic motivation when competing, 6) The
unmentioned importance of sport psychology services, and 7) The omission of information about
provincial versus national pride.

title: The impacts of environmental changes on peatland microbial community structure and function

subject:
peat
methane
carbon
bacteria
fungi
peatland succession
microbiology
chemistry
climate change

abstract:
Northern peatlands store approximately 30% of the world’s soil carbon, and are also
responsible for contemporary fluxes of the greenhouse gases carbon dioxide (CO2) and methane
(CH4), making them important players in the global carbon (C) cycle. These greenhouse gas
emissions are mediated by peat-dwelling microbes; however, the environmental factors
governing the structures and functions of peat microbial communities are still poorly understood.
In order to better understand these dynamics, I examined the effects of two forms of
environmental change on peatland microbial communities. Firstly, to gain fundamental
knowledge of the drivers of microbial community shift due to natural peatland succession, I
examined the effects of long-term peat transplantation from a rich fen to a late-successional poor
fen. This allowed me to evaluate the relative effects of solid phase chemistry and substrate
(largely determined by the parent material/vegetation) versus aqueous chemistry (influenced
more by groundwater or precipitation sources), on peat microbial communities. My results
suggest that solid phase chemistry, particularly total nitrogen (TN) and C:N, may be important in
determining the makeup of peatland bacterial communities. Secondly, I examined the effects of
soil warming simulating projected climate change in a poor and an intermediate fen on peat
microbial respiration and CH4 production as the preliminary stage of a multi-year, large-scale
field experiment. Soil warming did not lead to any effects on CO2 production or CH4 flux during
peat incubation.

abstract:
Chronic exposure to high levels of glucocorticoid hormones can be detrimental to survival and
reproduction. Captive breeding and release may inadvertently subject animals to conditions that
elicit an increase in glucocorticoids, if conditions in captivity or habitats in the wild are inadequate.
The critically endangered Vancouver Island marmot (Marmota vancouverensis) was used to investigate
variability in hair cortisol concentration, a measure of systemic glucocorticoid exposure. Marmots
were sampled from the captive, captive-release and wild populations. Captive animals had
significantly lower cortisol levels than wild animals. Several marmots were also sampled from the
historic wild population that lived on Vancouver Island prior to the proliferation of anthropogenic
disturbances. A comparison between contemporary and historic animals showed that marmots at
most colonies had cortisol levels that were the same as historic level. Three colonies had significantly
elevated cortisol levels. Cortisol concentration in the wild was best explained by proximity of a
colony to logging roads.

abstract:
Children and youth with significant mental health challenges often experience academic
and social-emotional difficulties at school. Early intervention is linked to improved mental health
and academic outcomes in school-aged youth. School boards across Ontario are adopting a
universal mental health promotion model where group programming is delivered to full
classrooms as a way to enhance wellness in schools. For my advanced practicum, I implemented
the Holistic Arts-Based Program (HAP) within the Rainbow District School Board with support
from various social workers, educators, and educational assistants. HAP is a group program that
teaches youth mindfulness skills and concepts through arts-based and experiential methods. The
HAP program is an enjoyable and engaging way to teach mindfulness to youth. My goal was to
explore the benefits of delivering arts-based mindfulness groups and methods in school settings.
HAP proved to be an excellent program to implement in schools as a way of fostering student
resilience, teaching coping skills, and building self-esteem, and self-awareness. Through artsbased and experiential methods, students can learn a variety of tools and strategies that will
enhance their wellbeing. Delivering HAP in various schools allowed students to build
connections with peers and their teachers. HAP also promoted inclusion, diversity, empathy, and
respect for others. Art-based methods enabled students to express themselves and learn about one
another in a creative, meaningful, and interactive way. School administration should consider
implementing arts-based mindfulness groups in classrooms when selecting universal promotion
programs for their schools. Schools are the ideal place to deliver effective and strengths-based
group work.

abstract:
Blood microsampling techniques, like Dried Blood Spots (DBS), have seen recent development
as an alternative to wet blood samples and offer numerous advantages. Quantification of ng/mLrange concentrations using DBS microvolumes (10-20 µL) is made possible with cutting edge
instrumentation. Worldwide establishment of per se limits for drug impaired driving requires
timely methods of sampling blood for accurate drug concentration measurements and
interpretation. The method validation for the analysis of stimulants and metabolites in DBS
samples by Ultra Performance Liquid Chromatography-Quadrupole Time of Flight-High
Resolution Mass Spectroscopy (UPLC-QTOF-HRMS) is presented. Limits of detection and
quantitation to 10 ng/mL was achieved. Method validation criteria was satisfied for 10 of 14
analytes. DBS drug stability over 8 weeks varied by analyte. DBS samples may assist in
overcoming challenges in blood sampling as they are less invasive, easily transported and stored,
and accurate drug quantitation even at low concentrations in DBS samples is possible.

title: Characterization of VR118 quinacrine derivative as a potential anticancer agent

subject:
anticancer agent
Quinacrine

abstract:
The discovery and development of effective chemotherapeutic agents in the past few decades
have immensely enhanced the treatment and management of human cancer. However, because
these drugs are associated with adverse side effects, high genotoxicity, risk for secondary cancers
and devastating effects on the patients’ immune system; the need for developing more effective
anticancer agents remains. A priority Research shows that 9-aminoacridine (9AA) derivatives
have substantial anticancer properties. The pharmacological properties of this agent are well
characterized and this scaffold has been widely used to treat different diseases for decades.
Quinacrine is a 9AA derivative, which was first discovered as an antimalarial compound in
1930’s and since then had been widely used in treating a variety of parasitic infections and
demonstrated potential for cancer treatment. Importantly, the polypharmacology of Quinacrine
makes it an attractive drug to treat a variety of cancers. Quinacrine acts by specifically targeting
cellular signaling pathways that play an important role in cell survival. Given the distinctive
cancer treating abilities of Quinacrine by specifically targeting cellular signaling pathways, it
was the objective of this study to develop a compound that has similar properties as Quinacrine
but has better efficacy and selectivity in targeting tumor cells. Therefore, for this project we
created derivatives of 9AA compound using hybrid pharmapore approach and examined one of
the derivatives of Quinacrine compound named VR118. After performing a series of experiments
to test the efficacy and selectivity of the Quinacrine derivative VR118, I came to the conclusion
that VR118 is highly effective in treating cancer cells and have the potential to selectively target
cancer cells without causing severe harm to normal cells at concentrations applicable for
malignant cell lines. This report discusses the efficacy and selectivity of VR118 compound in
targeting cellular signaling pathways and the mechanisms through which VR118 kills cancer
cells.

title: Stress episodes and adaptation in the National Hockey League according to Canadian professional hockey players from Ontario

subject:

abstract: Adaptation in professional sport is the professional athlete’s capacity to act and react effectively to destabilizing stress episodes so that an internal sense of emotional and psychological balance is restored (Schinke, Tenenbaum, Lidor & Battochio, 2010). Professional ice-hockey players must overcome numerous stressors throughout their careers in the National Hockey League (NHL). Though sport researchers have conducted preliminary studies about the stress and adaptation processes of NHL players, small participant numbers and the use of a structured interview guide limited to rookie and veteran career stages limit the conclusions. Based on these limitations, the purpose of the present dissertation was to provide a comprehensive depiction of the stress episodes and processes that lead to adaptation and maladaptation in the NHL. Twenty-three current and former NHL players were recruited for individual interviews, which were then analysed using Braun and Clarke’s (2006) inductive thematic analysis. As a result, stress episodes and the subsequent strategies attempted to reach adaptation or maladaptation could be housed either within a career stage or across an NHL player’s career. Career stages were (a) entry into the NHL, (b) remaining in the NHL, and (c) becoming an All-Star. Across-career stress involved (a) high profile team, (b) injury, and (c) relocation. Subsequently, the participants identified pathways designed to alleviate or manage the stressors situated within each stress episode. Through retrospection, the participants decided whether their pathways taken during various stress episodes were adaptive. Recommendations were then proposed by these athletes for aspiring NHL players or maladaptive. Implications for sport researchers and practitioners (e.g., coaches, mental performance consultants) are also provided within the conclusion.

abstract: The literature surrounding the educational experiences of Indigenous Peoples is an ever-growing and diverse area of research in Canada. However, within this field, the voices of First Nations mothers attending post-secondary needs further development. Through a decolonizing methodology and the use of autoethnography and Indigenous storytelling, this project was designed to explore and better understand our experiences as First Nations student-mothers during the pursuit of university-level education while caring for our children. I argue that Canada’s oppressive history of colonialism and the resulting intergenerational trauma have had specific implications on the post-secondary experiences of the First Nations mothers who participated in this research. The First Nations student- mothers from Laurentian University in Sudbury, Ontario, Canada who contributed to this research tell diverse stories about their experiences however, our narratives intersect in several ways. Areas of interest that emerged from the collected narratives include: (1) how we, as First Nations student-mothers have overcome obstacles, including what difficulties arose for us in the decision to pursue post-secondary education; what motivators contribute to our ongoing success, and how we experience self-doubt and internalized oppression despite our achievements and (2) how we, as First Nations student-mothers have blended our identities as First Nations women, mothers, and students within the university experience. Ultimately, this project aimed to contribute to continued efforts towards decolonization while furthering Indigenous-led research which hopes to improve the educational outlook for future generations of First Nations mothers.

title: Rites of passage for Algonquin & Ojibwe female adolescents: the Berry Fast experience

subject:
Berry Fast experience
rite of passage
Algonquin adolescent girls
Ojibwe adolescent girls

abstract:
There is a paucity of modern literature available on the Berry Fast experience which is a rite of
passage for Algonquin and Ojibwe adolescent girls. This thesis involved Algonquin and Ojibwe
adolescent girls who completed their Berry Fast—a rite of passage embarked upon by the
adolescent girls with the onset of menarche. The study participants also included the members of
a Community Advisory Committee. The adolescent girls who participated in the study have
chosen to revive a traditional First Nation rite of passage ceremony by completing the Berry Fast
despite the negative societal attitudes that surround menstruation within mainstream society.
Assimilation policies have also attempted to absorb the First Nations population into mainstream
society, but have not succeeded. Using a modified photovoice method, this researcher sought to
elicit answers to four questions regarding spiritual aspects, lived experiences, life changes and
the traditional First Nations’ views on moontime (menstruation). The results showed that the
Berry Fast strengthened a connection to Mother Earth, Creator, enhanced their understanding of
their traditional role as Anishnaabe Kweg (Aboriginal women), and culturally constructed a path
upon which they follow. The study also developed a model for informal, traditional knowledge
transfer. This thesis further discusses how the academic world, modified research
methodologies, and the urban Aboriginal community came together.

title: The impact of induced emotion on language

subject: language emotion

abstract: Through the investigation of the relationship between linguistics and cognition, it has been discovered that language differences can be found within individuals based on their current affective state. The current study examined whether the three dimensions of language (pleasantness, activation, and imagery) are evident in the language of participants after affective states have been manipulated. 60 Laurentian students were assigned to one of the three group conditions – positive exposure, negative exposure, or control. Participants were also divided by sex between the three groups. Participants were then asked to write a passage describing a personal event. Passages were examined using the Dictionary of Affect in Language (DAL) to determine the emotionality of the passages. Results were analyzed by conducting a 2x3 factorial MANOVA between subjects; the results failed to support the main hypothesis that the dimensions of language are impacted by emotion. However, results did indicate that females used language with more imagery and detail. Additionally, results indicated that event recall negativity was affected by emotion. Limitations, future directions, and implications are discussed.

Safety culture

abstract:
The purpose of this research was to review the commissioned occupational health and safety (OHS) reports in mining, over the past 50 years, in a two-step approach. The objective of the initial phase was to determine if there were any recommendations that were stated in more than one of the evaluated commissioned reports, that spanned the 50-year timeframe. The reports were selected through a review of the literature and in consultation with experts in OHS and mining. A multi-stage analysis was conducted on the recommendations, and identified 6 overlapping themes, and 49 sets of specific overlaps. In the second phase, a seeded analysis using a qualitative data analysis software, was completed to understand how safety culture was discussed in the reports. This was accomplished by completing a review of the literature to define safety culture, and to build the dictionary, which was seeded into the software. The analysis highlighted the use of various terms for safety culture throughout the 50-year history, with a particular emphasis on the fact that the term safety culture was not directly referenced in the selected reports until 1997.

title: Experimental and correlational evidence that biological systems are influenced by intensity and variation of geomagnetic fields

subject:
biological systems
intensity
geomagnetic fields
variation

abstract: Fluctuations in the Earth’s geomagnetic environment have been implicated in numerous biological processes as small as ion transport across a cellular membrane to as gross as the activity and behaviour of an individual. Treatment of demyelinated planaria with a six minute exposure to a magnetic field which simulates the onset of a geomagnetic storm resulted in a reduction of atypical behaviours that mimics observations of planaria not treated with a demyelinating agent. There was also a strong correlation observed between the North/South component of the Earth’s geomagnetic field and the prevalence of multiple sclerosis around the world. Increases in the local geomagnetic field strength due to geomagnetic disturbances can also influence the electrophysiological and negatively impact the sporting performance of athletes. These results indicate that biological systems are heavily influenced by changes in their geomagnetic environment, and certain disease acquisition and progression may be intrinsically tied to these energies.

title: Analysis of RBM5 and RBM10 expression throughout H9C2 skeletal and cardiac muscle cell differentiation.

subject: RNA Binding Motif (RBM) domain proteins

subject: RBM5

subject: RBM10

subject: Myoblast differentiation

subject: H9c2

subject: Alternative Splicing

abstract: RNA Binding Motif (RBM) domain proteins RBM5 and RBM10 have been shown to influence apoptosis, cell cycle arrest and splicing in transformed cells. In this study, RBM5 and RBM10 were examined in non-transformed cells in order to gain a wider range of knowledge regarding their function. Expression of Rbm5 and Rbm10, as well as select splice variants, was examined at the mRNA and protein level throughout H9c2 skeletal and cardiac myoblast differentiation. Results suggest that Rbm5 and Rbm10 may (a) be involved in regulating cell cycle arrest and apoptosis during skeletal myoblast differentiation and (b) undergo post-transcriptional or translational regulation throughout myoblast differentiation. All in all, the expression profiles obtained in the course of this study will help to suggest a role for Rbm5 and Rbm10 in differentiation, as well as possible differentiation-specific target genes with which they may interact.
