title: True lies : who can learn to tell?

subject: Deception Cues Detection

abstract:
Non-verbal cues can provide behavioural signals of deception to observers. Microexpressions
are facial cues that indicate the presence of an emotion being concealed by a
deceiver. During deception, deceivers often attempt to conceal an emotion by masking it
with an expression of another emotion such as a smile. Despite this, micro-expressions
may be leaked during masking to reveal the hidden emotion. Nonetheless, research has
shown that the majority of people recognize the occurrence of deception no better than
could be expected by chance. Micro-expression detection training has been suggested to
improve micro-expression detection skill that is linked to improved deception detection.
The present study examined the effectiveness of the Micro-expression Training Tool
(METT) in improving students’ and police officers’ skills in detecting masking smiles.
The visual attention of trainees and untrained controls was measured via eye tracking
during a pre and post test masking smile detection task. Results revealed that training did
not have an effect on task performance, but practice did alter task performance.
Following practice, all groups showed better detection of true smiles but not for masking
smile detection. Participants’ abilities to identify masked emotions and location of microexpressions
on the face varied as a function of the emotion present, as did their attention
to the relevant regions of the face that contained a micro-expression. These results
suggest that traditional micro-expression training is not sufficient to train observers in
masking smile detection. This result has significant implications for future training
protocols and many professional groups, as masking smiles are often employed during
attempts at deception.

title: Incorporating expressive play techniques within brief service: observed applications within children's mental health

subject: play therapy models

subject: Keystone Child Youth and Family Services

subject: expressive play techniques

subject: models of brief service

subject: experiential learning

subject: practical application with families

abstract: Although models of brief service and play therapy appear to contrast with one another, the underlying tenets of humanistic theory and post-modern social constructivism suggest complimentary combinations within clinical practice. This advanced practicum research report examines my practicum experiences within a children’s mental health agency in relation to the compatibility of brief service and expressive play techniques in applied practice. My goals within the practicum were to enhance and strengthen my clinical skillsets as a practitioner through case interventions and supervision. I was also interested in developing a personal practice model regarding the application of expressive play techniques within a brief service delivery approach.  Throughout the report, I will highlight the major themes revealed within my reflective practice and demonstrate the growth of my theoretical knowledge and clinical skillsets throughout the practicum process. The critical analysis of the practicum highlights two distinct observations and insights within my experiences. The first section of analysis includes applications of expressive play techniques within an agency setting, and observations from practical application with families. The second section of analysis will describe themes that emerged through my own self-discovery and the conceptualization of my therapeutic process. Throughout the process of the practicum, I developed an understanding and experience of my therapeutic stance, nurtured my own self-awareness/personal mindfulness practice, and acknowledged the value of combining narrative brief service and play therapy models through experiential learning.

title: Sedimentology, stratigraphy, geochemistry, geochemistry and diagenesis of giant lacustrine carbonate seep mounds (Ikpiarjuk Formation), Mesoproterozoic Borden Basin, Nunavut, Actic Canada

subject:
Mesoproterozoic
carbonate sedimentology
alkaline lake
lacustrine carbonate

abstract:
The Ikpiarjuk Formation consists of a group of very large (kms long and hundreds of metres
thick), isolated, deep-water, vent-related dolostone mounds that are unlike any documented
example of vent-related carbonate rocks in the geological record. The mounds lack ‘normal’
features of Proterozoic carbonates: the mounds contain thrombolites (microbially clotted
carbonate), formed below the photic zone, and lack the stromatolitic fabric characteristic of most
Proterozoic reef structures. The sedimentology, stratigraphy, geochemistry, and diagenetic
history of the mounds were investigated through field work, standard petrographic methods, and
various geochemical and other analytical techniques.
Shale-normalised rare earth element patterns of various depositional components of the mounds
depicts binary mixing between basin-water-derived precipitates and seep-fluid-derived
carbonate. Basin fluid has characteristics that are consistent with deposition in an alkaline lake,
and seep fluid features are consistent with circum-neutral groundwater that had interacted
extensively with basement blocks before seeping into the lake bottom through faults.
The sedimentology and mineralogy of the mounds indicates that they were formed by
thrombolites that were made up of a microbiota that was not photosynthetic or aerobic. The
Ikpiarjuk Formation thrombolite microbiota was probably dominated by an anaerobic
chemoautotrophic or chemoheterotrophic metabolism, and records visible preservation of a
community that has never before been described from the Mesoproterozoic.
The diagenetic history of the Ikpiarjuk Formation is complicated. Dolomitisation occurred early
during diagenesis, and subsequently, five different fluids flowed through primary pore space in
the mounds and precipitated successive generations of cement. One of the cements contains
sulphides inclusions and may correlate with base-metal bodies elsewhere in the basin.

This thesis explores the history of the Society of Jesus and its efforts at missionary work
from the 17th century in New France to the 20th century in Canada and the use of architecture
and landscape development to settle and convert Indigenous peoples into Euro-Christian
communities. The Jesuits focused on using Indigenous children to aid in the conversion of
Indigenous societies and their efforts resulted in the residential school complexes of the 19th and
20th century in the villages of Wiikwemkoong and Spanish, Ontario. Using illustrations,
photographs and written descriptions of former student experiences the atmosphere of the
physical environments in Spanish are depicted. The ambitious land and architecture strategies of
the Society contributed to the failure of the Spanish Indian Residential Schools. The thesis
concludes with a discussion regarding the former sites of the Jesuit residential schools in
Northern Ontario and the current discourse on Canadian residential school buildings and sites in
the media.

subject:
Bacteria
Antibiotic Resistance
β-Lactamases
Bacteria, AntMetallo-β-lactamases

abstract:
Metallo-β-lactamases (MBLs) are major contributors to bacterial antibiotic resistance due to their
ability to cleave most β-lactam antibiotics. At the present time there are no clinically approved
inhibitors of MBLs. However, previous preliminary studies have demonstrated that cationic
peptides have the ability to inhibit these enzymes.
Herein, more thorough investigations into the structure-activity relationship between two
MBLs, VIM-2 and IMP-1, and cationic peptides are described, demonstrating that the inhibitory
potency of these peptides increased with the number of arginine residues (IC50 of 10 nM for the
most potent VIM-2 inhibitor). The degree of inhibition also varied depending on the β-lactam
substrate and the MBL employed. Furthermore, steady-state and stopped-flow
spectrophotometric studies demonstrated that the inhibition mediated by these peptides followed
a complex mode of inhibition. In addition, results from spectroscopic studies (including UV-Vis,
tryptophan fluorescence and dynamic light scattering) showed that the inhibition of MBLs by
cationic peptides results in partially reversible peptide-influenced MBL aggregation. The better
understanding of the relationship between these peptides and MBLs may lead to the development
of novel MBL inhibitors suitable for clinical use.

Prevention
Holistic care
FASD informed approaches
Capacity building

abstract:
Neurological, physical and developmental impairments resulting from prenatal alcohol exposure (PAE) fall along a spectrum and under the umbrella term Fetal Alcohol Spectrum Disorders (FASD). It is important to understand that FASD is in fact, brain damage. These disorders and their variations are complicated and often misunderstood. This often results in distressing outcomes, such as failed school experiences, trouble with the law, strained relationships, and home and placement breakdowns. The circumstances are often made worse by the lack of reliable screening, assessment and effective support services available to individuals and families across Ontario.
This qualitative study explored the impact of PAE, the assessment and support capacity within Ontario and ministry mandates that guide service provision in the areas of health, mental health, education and justice. An integrative review of the literature was undertaken and the results found that there are significant gaps in the current service delivery systems, but there are mandates that present viable options to consider in order to address the gaps and improve the circumstances for those affected by PAE. The findings led to three recommendations that address cross sectorial collaborations, policy development for FASD informed approaches, as well as professional development and prevention efforts. The implications for the field of social work are also presented.

subject:

McConnell Taping
Osteoarthritis

abstract:
The effect of the McConnell medial taping technique on patellar alignment and perceived
knee pain in patients with patellofemoral pain syndrome (PFPS) between the ages of 20-
50 years old was examined in this study. Clinical patellar alignment was assessed with
the McConnell and Herrington manual patellar measuring technique while pain measures
were assessed using a visual analogue scale (VAS). These measures were collected at
three-times during a 4-week treatment protocol: prior to treatment, mid-way treatment
and 24 hours after treatment. This study included two therapy groups: one received a
standard 4-week therapeutic exercise program for PFPS and the other underwent the
same standard 4-week exercise program with the inclusion of McConnell’s taping
technique. No statistically significant differences were found before and after treatment
for pain or patellar alignment in either group. Nonetheless, upon plotting the results a trending decrease in pain for all patients irrespective of group was noted, which raises the
question of possible underlying effects influencing pain such as the patellofemoral
contact area. Although it appears that the McConnell taping technique had no added
benefit when combined with the standard exercise program, this study reaffirms that
exercise therapy continues to have a positive effect on PFPS. In conclusion, we speculate
that changes in patellofemoral joint (PFJ) contact area may be the primary reason that
pain decreases for PFPS patients.

abstract: Uncaria tomentosa is a medicinal plant native to Peru which has been used traditionally for the treatment of various inflammatory disorders and cancer. Some studies have shown that treatment with Uncaria tomentosa promotes repair of cellular DNA in patients treated with chemotherapy drugs, preventing mutations and cell damage. Treatment with Uncaria tomentosa also inhibits inflammatory responses by inhibiting the proliferation of T and B-lymphocytes and decreasing the production of pro-inflammatory cytokines (IL-1, IL-6, and TNF-α). We have examined the effects of Uncaria tomentosa extracts on the growth of malignant cells such as MCF-7 and MDA-MB-231 cells, human breast cancer cell lines and non-malignant cells such as HBL-100, HEK 293T and HSG cells. Our results have shown that treatment of malignant cells and non-malignant cells with Uncaria tomentosa extracts inhibits their proliferation and promotes cell death in a dose-dependent manner. Further, extracts produced by boiling the ground bark in 70% ethanol are much more effective than extracts produced by boiling in water. Uncaria tomentosa-ethanol extracts potently induce cellular apoptosis as measured by changes in cell morphology, chromatin condensation (Acridine Orange/Ethidium Bromide staining assay) and DNA fragmentation (TUNEL assays) within 24 h of treatment. Overall, Uncaria tomentosa appeared to kill breast cancer cells effectively in vitro by increasing cellular apoptosis.

abstract:
L’objectif de cette thèse était d’explorer, selon une approche interdisciplinaire et qualitative les besoins et les intérêts d’apprentissage des personnes aînées francophones de l’Ontario et de déterminer les facteurs qui, selon elles, influencent leur apprentissage. La question principale qui a guidé cette recherche cherchait à savoir ce qu’apporte la perspective des personnes aînées à la connaissance gérontagogique et à la théorie de l’apprentissage en général, compte tenu des connaissances relatives à la cognition et à l’éducation, compte tenu aussi des pratiques en cours. Nous avions posé deux hypothèses à savoir que, d’une part, pour les personnes aînées francophones, l’apprentissage au troisième âge contribue positivement à leur bien-être en société, à leur santé et à leur mieux-être et, d’autre part, pour les personnes aînées francophones la langue est un facteur important les incitant à participer aux activités d’apprentissage dans leur milieu. Pour répondre à l’objectif de notre thèse, nous avions eu recours à la théorisation ancrée qui est une approche permettant de saisir mieux l’articulation entre la théorie et le terrain (Glaser et Strauss, 2010). Cette articulation a été possible grâce à l’analyse des témoignages de groupes de discussions en relation avec le concept de gérontagogie.
Les résultats de notre thèse se présentent sous la forme d’une contribution théorique et conceptuelle à la gérontagogie en tant que discipline en émergence. Le témoignage des personnes aînées, jusqu’à présent absent des débats, apporte une contribution importante et un éclairage nouveau en permettant d’établir un pont entre la théorie et l’application des connaissances sur le terrain. Cette étude révèle des résultats et propose une structure de base aux connaissances relatives à la gérontagogie sous l’optique de cinq principales dimensions que sont: la perception de l’apprentissage, les besoins d’apprentissage, les intérêts d’apprentissage, les méthodes d’apprentissage et les barrières et appuis à l’apprentissage au troisième âge. Nous avons atteint certains points de saturation en rapport avec l’apprentissage continu et la santé, ainsi qu’en relation avec l’apprentissage continu et l’importance de la langue française. Cette thèse a mené à des conclusions importantes pour l’avenir d’une science de l’éducation pour les personnes du troisième âge, pour la gérontagogie.

title: Determining the feasibility of a real-time geophysical magnetic and electric measurement system for monitoring strain underground

subject: Stress Strain Electric Magnetic

abstract:
In deep mining environments, rockbursts can occur in areas of high stress. The unpredictable nature, and sometimes fatal consequences of the rockbursts, makes identifying increases in stress
that occur prior to failure events, important for mine safety. The piezoelectric, electrokinetic, and seismo-electric/magnetic effects result in rocks that are stressed emitting electric and
magnetic fields that can potentially be measured in (or close to) a rock mass. Electric, magnetic and seismic data were collected during a four-day period at Coleman Mine, Sudbury, Ontario,
and later analysed. No signals due to strain were evident in the magnetic or electric data, so a more careful three-part experiment was proposed to see if strain related signals could be identified in magnetic data. In the first part of the experiment thirty-two rocks were stressed
until failure. Measurable magnetic signals associated with audible cracking sounds were found for most rock samples, as well as consistent signals across all samples prior to failure. The implementation of real-time monitoring of these signals has the potential to significantly improve
deep mine safety by mapping the evolution of strain underground and potentially indicating areas susceptible to failure.

subject:
Oelwein Method (OM)
autism
literacy instruction models.

abstract:
The purpose of this paper is to examine a strength-based reading instruction method for
individuals severely affected by autism who do not respond well to typical literacy instruction
methods, called the Oelwein Method (OM). Due to the unique learning profile of strengths and
weaknesses in individuals with severe autism, they often do not respond well to typical literacy
instruction models. This paper examines the unique learning profile of individuals with autism
and why the OM is an effective literacy instruction model for this population of learners.
Phonics-based and sight word-based approaches are compared, with a focus on the effectiveness
of these approaches for individuals with autism. The materials and instructional process of the
OM are explained, including empirical evidence that supports the different instructional
components used in the OM. The Ontario Ministry of Education’s policies are reviewed, along
with how the OM satisfies these policies. Methods to improve the OM are explored as well as
directions for future research that would need to occur before widespread implementation could
take place.

abstract: My Master of Social Work practicum took place in a non-‐profit social service agency with the City of Greater Sudbury called The Family Enrichment Centre. This agency specialized in providing therapeutic mental health services to a cross section of people within the Greater City of Sudbury and surrounding communities.I had two primary goals. The first was to learn different treatment modalities in my clinical work with individuals that fit within the Strengths Perspective. The second was to utilize clinical supervision in its various forms to further develop a reflexive clinical orientation.  I was able to build upon my existing experience with treatment modalities I had previously used and to practice some new treatment modalities by using the clinical structures and resources built into the agency. These clinical structures and resources included common intake, assessment and recording tools as well as training opportunities and information on a variety of clinical modalities.  I was also able to develop a more reflexive practice through the use of one to one clinical supervision with a clinical psychologist, ad hoc individual supervision/consultation with other therapists and regular group consultation with other therapists. Participation within their anger management group and bi-‐weekly individual spiritual presentations where each individual therapist shared their unique spirituality provided a work environment with reflection built into it and was in itself a primary tool in building reflexivity into my clinical practice within the Centre.

abstract:
This thesis explores the world of the visibly tattooed individual from their own
vantage point, particularly in the work environment and whether, as well as how, tattoos
have affected their career prospects in terms of being hired and promoted. Accordingly, I
will examine how an image or symbol that is visible on the skin can have different
perceptions by management and how it is perceived by, and effects, those with visible
tattoos in the workplace. My goal is to ensure that non-tattooed individuals are able to
understand that tattoos are more than just ink on the skin to be judged, particularly by
those holding power in the workplace. From the standpoint of a heavily, visibly tattooed
mothers, women and students I have a firsthand view of the difficulty society places on
visibly tattooed people. Utilizing field research via a qualitative approach, I conducted
and analyzed thirteen interviews. Utilizing interviews this enabled me to capture the
experiences of participants whether management at a workplace, or visibly tattooed
employees. Results indicate that tattoos have recently become more accepted to a certain
degree, dependent on several factors, including the fine line between an individual who
has a few visible tattoos and others who have what I have labelled ‘body projects.’ I
conclude that stigma and judgment in the workplace are very much alive for tattooed
individuals and will continue to affect their job prospects in the short-term.

title: Biochemical adaptations in pseudomonas fluorescens exposed to nitric oxide, an endogenous antibacterial agent

subject:
Metabolism
Bacteria
Nitric oxide
Reactive Nitrogen Species

abstract:
Nitric oxide (NO), a free radical released by macrophages (a subset of white blood cells) as a response to infection, is noxious to organisms due to its ability to disable crucial biomolecules such as lipids, proteins and DNA. Although normally effective at eradicating invading bacteria, several pathogens have developed mechanisms to detoxify NO and its toxic by-products, reactive nitrogen species (RNS). While some of these detoxification processes have been characterized, very little is known about the metabolic changes that enable microbes to survive this deleterious environment.
Investigations into the effects of RNS on microbial physiology have shown that these harmful radicals inactivate the citric acid cycle and oxidative phosphorylation, the series of reactions responsible for making energy aerobically. The central aim of this thesis was to determine how the organism counteracts the detrimental effects of RNS, while bypassing the ineffective central metabolic pathways. The findings presented herein show that P. fluorescens engineers an elaborate metabolic network to generate ATP whilst withstanding the injurious effects of nitrosative stress. Crucial to this adaptation is the ability to produce energy via substrate level phosphorylation, a necessity that arises out of the cells’ inability to produce a substantial amount of ATP using the electron transport chain (ETC).
The up-regulation of the enzymes citrate lyase (CL), phosphoenolpyruvate carboxylase (PEPC) and pyruvate, phosphate dikinase (PPDK) helps the organism accomplish this feat. Blue native polyacrylamide gel electrophoresis (BN-PAGE), high performance liquid chromatography (HPLC) as well as co-immunoprecipitation (CO-IP) studies were applied to demonstrate that these proteins form a metabolon, a transient complex of enzymes that ensures citrate is converted into its desired end products, pyruvate and ATP. In order to gauge the individual contributions
iv
of phosphoenolpyruvate-dependent kinases, a novel in-gel activity assay was developed to probe these enzymes under disparate conditions.
These results suggest that the organism switches from an ATP-dependent metabolism to one based on the utilization of pyrophosphate (PPi). The rationale for this appears to be energy efficiency, as pyrophosphate-dependent glycolysis can theoretically produce five ATP rather than the two yielded by Embden-Meyerhof glycolysis. Additionally, the up-regulation in activity of the enzymes adenylate kinase, nucleoside diphosphate kinase and acetate kinase seem to ensure that ATP generated by PPDK is properly shuttled and stored when aerobic metabolism is defective. The lower activity of inorganic pyrophosphatase likely ensures an adequate supply of pyrophosphate for the activity of PPDK.
Taken together, this research reveals the critical role metabolism plays in the survival of microbes under the onslaught of NO and RNS. As several of these enzymes are absent in mammalian systems, they present themselves as novel targets for the development of new antibacterial agents. A comprehensive awareness of bacterial defense systems in response to NO may lay the groundwork to developing more effective treatments to impede microbial infections.

title: Effects of virtual group size on conformity.

subject:
group size
conformity

abstract: Conformity research in the past has relied on the use of confederates to examine conformity. Modern technology, however, has eliminated the need to involve confederates. Computers, and in particular, online social networks, can be used instead of live confederates with only the idea of other people being needed to pull off a conformity study. While the use of technology is nothing new, the use of social networking in conformity research is limited (Egebark & Ekström, 2011). The current study explores how this phenomenon can be applied to the online world. Twenty-eight Laurentian students were given informed consent and received bonus marks for participation at their Professors’ discretion. All participants completed four tasks on a specially designed computer program created by Professor Stan Koren. Once complete, participants were given a full debriefing which explained the true nature of the study and offered to have their data removed if they wished. Results indicate conformity can happen even in the absence of other people, with minimal stimuli necessary to elicit a conforming response. Results also show informational (desire to be right) conformity dominates normative (being liked) conformity. Limitations, implications and future directions are discussed.

subject:

abstract: There is a paucity of studies on the natural variation in sperm morphometry and motility in a single species across dissolved oxygen regimes. This study measured the natural variation in reproductive traits including sperm morphometry and motility of male Pseudocrenilabrus multicolor victoriae across a wide range of habitats in Uganda, Africa. I investigated whether fish displayed differences in testes mass, testes asymmetry, sperm morphometry, and sperm motility. P. multicolor were collected from nine sites characterized by three oxygen regimes: seasonally fluctuating, hypoxic and normoxic. Fish traits were measured and analyzed by site and by oxygen regime. I found that P. multicolor display variation in reproductive traits across habitats, and that males in hypoxic regimes are smaller bodied, have lower testes asymmetry, shorter sperm, and a higher sperm velocity relative to males in normoxic or fluctuating regimes. Males may be able to invest more energy into reproduction in hypoxic sites due to a lack of predators in these sites. Additionally, over the long term, males in hypoxic sites may have locally adapted to chronic conditions, allowing them to invest more energy into testes and sperm to offset the costs of living under hypoxia. In contrast, males from the fluctuating regime were large bodied, had high testes asymmetry, and the longest sperm with the lowest sperm velocity. Males in fluctuating regimes may be experiencing energetic trade-offs between growth and reproduction, due to the less predictable oxygen levels in their habitat. Future studies should assess P. multicolor for trait differences across oxygen regimes in a split-brood laboratory study to control for confounding effects of food availability, predation risk, and mating competition on reproductive traits.

abstract:
The purpose of this research study was to explore the social construction of women’s
cardiovascular disease, identities and health within Glamour magazine, a corporate partner of
The Heart Truth® campaign. The Heart Truth campaign was implemented as a United States
(U.S.) national action plan in 2002 to increase women’s awareness about their leading cause of
death (i.e., cardiovascular disease), and encourage women to take action to manage various risk
factors. By conducting an ethnographic content analysis of relevant information within the
inaugural October 2003 issue of Glamour, the following themes were identified: (a) a culture of
consumerism (overarching theme); (b) the oblivious, unknowledgeable, dependent woman at risk
(sub-theme); and (c) attaining a particular version of a healthy, feminine woman. These findings
reveal the problematic ‘feminization’ of cardiovascular disease through the promotion of
heteronormative ideals and gendered social order, and dependency on broader institutions and
corporations.

title: Mine schedule optimization with geotechnical constraints

subject:
Mining schedule optimization
geomechanical stability
time-dependent rock deformability
excavation sequencing

abstract:
If a mining project consists of n stoping activities these can be scheduled in n! ways according to
the duration between the activities and their precedence. Mine schedule optimization
manipulates the precedence relationships and the duration of the mining activities in order to
maximize the Net Present Value (NPV). However, unexpected instabilities may impede or
disrupt the schedule and thus reduce the profitability and so geotechnical aspects of the operation
need to be taken into account.
The mine schedule optimization software considered in this work is the so-called Schedule
Optimization Tool (SOT). This thesis reports the work for development of new geomechanical
constraints for any mine scheduling tool to find the safest and the most profitable schedule,
exemplified within the SOT framework.
The core hypothesis of this research is that there is a time-dependent aspect of the rock behaviour
that leads to instability, a consequence of dependence of geotechnical instability upon the
sequence and duration between stoping activities. There is evidence presented in this work that
supports this hypothesis.
An automated procedure for timely and computationally efficient calculations of the instability
metrics is presented. This can be applied to evaluate the geomechanical stability of any of the n!
schedules for excavating n stopes or applied to evaluate geomechanical stability of schedules
arising in the schedule optimization process. However, in practice, the number of feasible
schedules is much less than n! due to the precedence constraints. The approach starts with
computing n elastic stress fields induced after excavating each individual stope independently
within an identical computational domain using Compute3D. The stress-time series of each
iv
and/or every sequence of stoping are generated through superimposition of these pre-computed
stress fields, and the time stamps of blasting for excavation are allocated corresponding to the
stoping timetable. Different blasts are allowed to be timetabled at the same time. By means of
Hooke’s law and the 3D Kelvin-Voigt creep model the elastic strain time series and the
viscoelastic strain time series are produced for the stress-time series. Based on the Mohr-
Coulomb Failure criterion three (in)stability indicators are defined:
i. ‘Strength Factor’ to evaluate state of stress at each stage of each schedule as a proportion
of is strength
ii. ‘Strainth Factor’ to evaluate state of elastic strain at each stage of each schedule as a
proportion of a limiting ‘rupture’ strain
iii. ‘Viscoelastic-strainth Factor’ to evaluate state of viscoelastic strain at each stage of each
schedule as a proportion of a limiting ‘rupture’ strain.
To provide a perspective of the (in)stability condition in the computational domain for all the
feasible sequences of stoping, 12 (in)stability metrics were defined and the results of each are
illustrated in the form of ‘(in)stability indicator diagrams’. The overall methodology is applied
to an example of excavating 6 open stopes.
Additionally, a methodology is theorized to evaluate the stability condition in the rock mass
surrounding the stopes for a series of stoping and backfilling schedules. The methodology is
based on pre-computing one additional stress field element for each stope, which represents the
effect of the fill loading on the rock mass. The calculations for this approach are consistent with
the time and computational efficiency of the original methodology. The computational effort
v
increases to ‘2n’ pre-computed stress fields rather than ‘n’: as problem sizes double,
computational time doubles, rather than increases in polynomial or exponential time.

abstract: Physical phenomena occur within a complex manifold of interactions from small scale quantum to large scale energies. These random interactions appear to conform to the central limit theorem, however prediction of these events suggest a non-local factor is typically involved. Data were compiled from a random number generator that utilizes quantum electron tunneling, a photomultiplier tube measuring background photon emissions (~10-11 W/m2), earthquakes recorded by USGS Advanced National Seismic System, and from a database of human electroencephalographic recordings. The data indicated temporal and spatial relationships, suggesting the causality of physical phenomena and the associated entropy conforms to the central limit theorem by means of variable distribution of occurrence.

abstract:
The purpose of this thesis is to introduce the reader to Multiple Regression and Monte
Carlo simulation techniques in order to find the expected compensation cost the insurance
company needs to pay due to claims made. With a fundamental understanding of probability theory, we can advance to Markov chain theory and Monte Carlo Markov Chains
(MCMC). In the insurance field, in particular non-life insurance, expected compensation
is very important to calculate the average cost of each claim. Applying Markov models,
simulations will be run in order to predict claim frequency and claim severity. A variety of
models will be implemented to compute claim frequency. These claim frequency results,
along with the claim severity results, will then be used to compute an expected compensation for third party auto insurance claims. Multiple models are tested and compared.

abstract:
The mining sector has seen an increase in costs associated with the use of energy in recent decades. Due to lower ore grade, deeper mineralization, or more remote location new mines generally require more energy to produce the same amount of mineral. Mining operations require reliable and cost-effective energy supply, without which extraction becomes economically risky, as well as unsafe for miners. Commercial software and research-oriented computer models are now available to assist in the decision making process regarding the optimal selection of Energy Supply Systems (ESS) and associated costs. However, software and models present limitations: some are designed to minimize the cost of supplying only heat and electricity, while others are custom applications for the residential and commercial sectors. Most computer tools assume invariable operating conditions, e.g. energy supply and demand profiles that do not change throughout the lifetime of
the mine, or conditions whose variations can be perfectly predicted. As a result, the optimization of ESS can yield designs that lack robustness to deal with real life, changing environments. Under the same approach, the Optimal Mine Site Energy Supply (OMSES) concept was originally developed as a deterministic mathematical programming tool to find the optimal combination of energy technologies and sources that could meet final energy demands. The solution also included the optimal operation strategy based on typical energy demands of a specific mine site. This thesis expands OMSES to address the robustness of the solution, by considering the uncertainty and variability of real operating conditions. A method is proposed herein, based on the optimal solution obtained by OMSES and utilizing Model Predictive Control (MPC). The
MPC-based simulation under changing environmental conditions ensures that energy demands are met at all times, taking into account energy demands and supply forecast, as well as their inherent variability. Results show that near optimal, more robust design solutions are obtained when the system is simulated under uncertain, more realistic operational conditions, leaving MPC in charge of exploring under-capacity events and of redesigning the system to ensure feasibility with minimum cost increase. This new method has been termed MPC-OMSES dynamic redesign. This thesis also reports on research work to adapt OMSES formulation to account for varying demands throughout the life of the mine, as a consequence of the natural process of mine development and extraction, which means deeper operations over time. This process entails a progressive increase in energy demands, and therefore the energy supply system must be
planned accordingly. The proposed Long Term OMSES (LTOMSES) shows the advantages of considering an investment plan for the ESS, especially in the case of capital-intensive renewable energy technologies. Other concepts that have been integrated in OMSES and are covered in this thesis include: (i) material flows with considerable impact in the energy consumption have been included in the mathematical formulation, in combination with the corresponding technologies, such as pumps, fans and mobile equipment; (ii) energy and material storage have been also included, along with complex utility tariff structures, and grid and pipeline extensions. More innovative and integrated solutions can be considered by expanding the feasibility region of the optimization problem, as shown in a case study covering the integration of battery-powered electric underground mobile equipment. Overall, this thesis provides insight and tools to assist engineers in the important task of designing comprehensive and cost-effective energy supply systems for underground mines. Future work suggested includes: the development of a methodology to design fully adaptive
ESS (not considering a pre-existing optimal or sub-optimal design); the simultaneous optimization of the production plan (ore extracted per day) and the design and operation of the ESS; and a dynamic approach to review the investment plan in the face of long-term environmental operating conditions.

abstract:
The consumption of freshwater fish and seafood is the main source of mercury
(Hg), a widespread neurotoxic pollutant, in humans, a fact which has sparked decades of
research on Hg cycling in aquatic systems. More specifically, the formation and
bioaccumulation of methylmercury (MeHg) is of particular importance because it
biomagnifies through aquatic food webs, resulting in relatively high levels in predatory
fish despite typically low concentrations in the surrounding water.
The main goal of this thesis was to assess how various watershed-level processes
affect Hg bioaccumulation and biomagnification through freshwater food webs across the
relatively pristine Attawapiskat Drainage Basin (ADB) in the remote Far North of
Ontario. This watershed overlaps with the mineral-rich region known as the “Ring of
Fire” which is expected to be heavily developed in the coming decades, likely altering the
physico-chemical environments of surrounding lakes and rivers. In total, 58 lakes and
river sites across the ADB were sampled for surface water quality, aquatic
macroinvertebrates, and fish from 2014 to 2016. Water samples were analyzed for 39
chemical parameters including total Hg (THg; the sum of all Hg species) and MeHg
concentrations ([MeHg]). Biotic samples were analyzed for [THg] and/or [MeHg], as
well as carbon and nitrogen stable isotope ratios, which are indicative of an animal’s food
web position.
In Chapter 1 of this thesis, I provide an overview of our current knowledge on Hg
cycling in aquatic systems of the boreal region. In Chapter 2, I present an extensive
assessment of the chemical, physical, and ecological gradients across the ADB, and an
analysis of the relationships between Hg and these environmental gradients. I determined
that less productive systems with higher concentrations of dissolved organic matter
(DOM) had higher aqueous and biotic [Hg]. In Chapter 3, I examined how changes in the
quality of DOM across the ADB relate to [Hg] in water and biota. Findings from this
study suggest that more labile DOM complexes enhance MeHg bioaccumulation into
food webs, while systems with more humic and aromatic DOM had higher aqueous total
[Hg]. The fourth chapter critically examined the speciation of Hg in fish from across the
ADB and showed substantially lower percentages of MeHg (relative to total Hg) in
muscle of smaller-sized fish, particularly those which feed on littoral-based food webs
and had higher lipid content in their tissue. These novel findings challenge the general
assumption, used in many biomagnification studies and consumption guidelines, that all
fish muscle tissue has > 95% MeHg. Finally, in Chapter 5, I discuss the implications of
my research for subsistence fishers, specifically those from remote communities, where
freshwater fish are important for both culture and sustenance. Here I developed some
preliminary approaches to better communicating the risks and benefits of consuming fish
when presenting fish tissue contaminant results in remote northern communities,
including those in and around the ADB.
Understanding the major influences on MeHg cycling is vital to properly
monitoring the effects of industrial development (e.g., the Ring of Fire development) and
climate change, which can greatly alter the physico-chemical environment of surrounding
lakes and rivers. The results from my thesis indicate significant physical and chemical
differences between waters in the two ecozones (i.e., the Boreal Shield and Hudson Bay
Lowlands) across the ADB, presumably due to changes in bedrock geology and riparian
characteristics. No other study, to my knowledge, has explored the effects of landscape
position and the associated changes in physico-chemical characteristics on Hg
bioaccumulation, speciation, and biomagnification on such a large scale. My findings
demonstrate that monitoring programs will need to effectively track changing nutrient
concentrations, DOM characteristics, and Hg bioaccumulation patterns that vary across
large spatial gradients.

appetite

abstract:
Ghrelin is a stomach derived hormone that stimulates appetite. H2S a gaseous signaling molecule
also produced in the stomach has been implicated in the secretion of other metabolic hormones.
We hypothesize that H2S can directly suppress ghrelin secretion leading to a reduction in
appetite. We tested this by treating ghrelin producing rat primary stomach culture with the H2S
donor molecule GYY4137 or H2S synthesis inhibitor PPG. GYY4137 dose-dependently
suppressed ghrelin secretion, while increasing cellular levels of phosphorylated AKT/Total AKT.
Additionally, fluorescent immunocytochemistry demonstrated of that ghrelin cells co-localize
with the H2S producing enzyme, CSE and inhibition with PPG stimulated ghrelin secretion. In
mice, a single IP injection with GYY4137 (30mg/kg) prolonged glucose induced suppression of
ghrelin compared to saline control. This lower level of ghrelin was accompanied by a reduction
in feeding (P<0.05). In conclusion, our data demonstrates that H2S has a suppressive effect on
ghrelin secretion and appetite.

subject: Perception du tempsaccélération temporelle

abstract: La perception du temps au cours de la vie est un objet d’étude plutôt négligé par la science. Jusqu’à récemment, l’étude scientifique de la perception temporelle se limitait surtout aux jugements de durées physiques de l’ordre des millisecondes, des secondes et des minutes. Cependant, depuis le tournant des années 2000, un intérêt scientifique grandissant se manifeste pour des jugements de durées physiques beaucoup plus longues, de l’ordre des années et des décennies. C’est dans ce contexte que des équipes de recherche tentent maintenant de circonscrire un phénomène qui, jusqu’à présent, avait été abordé de manière plutôt marginale : l’accélération subjective du temps avec l’âge. En effet, depuis une cinquantaine d’années, plusieurs chercheurs se sont efforcés, par l’entremise d’expériences pionnières, de mesurer ce phénomène. Cette littérature est revisitée aujourd’hui, dans la mouvance d’une société démographiquement vieillissante. Si bien qu’une nouvelle discipline scientifique se dessine à l’horizon : la chronobiologie, l’étude de l’expérience temporelle subjective au cours de la vie. Le présent mémoire vise à rendre compte des plus récentes avancées empiriques et théoriques sur l’accélération du temps psychologique avec l’âge, le phénomène central qui a présidé à l’émergence de la chronobiologie. La définition du phénomène de l’accélération subjective du temps avec l’âge mène à l’examen de son caractère soit unitaire ou multidimensionnel. Les théories présentées dans la littérature sont variées en valeur explicative, mais semblables en guise de méthodologie, en bout de ligne. Le développement d’une méthodologie propre au domaine importe ainsi qu’un sens de l’application pratique dans nos communautés.

abstract: The influence of chemical additive and deposition time on the morphology of short-time zinc electrodeposits was studied using Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM) and scaling analysis. SEM and AFM were utilized to capture high-resolution images of zinc samples produced between 10 and 90 minutes of deposition from an electrolyte with a composition similar to that being used in the industry. Scaling analysis of the 3D AFM images was used to quantify surface roughness including root-mean-squared (rms) roughness, feature widths, roughness to width ratios, and their rates of change. Insight on the growth mechanism for these short-term deposits was achieved using scaling analysis. Within the deposition conditions studied, results showed that zinc deposit morphology is influenced by the relative proportions of bone glue, sodium silicate and licorice additives.

abstract:
Environmental attitudes are shaped by a variety of factors including our educational history, cultural background, childhood and life experiences, and past and current interactions with nature. This research set out to examine attitudes toward the environment in an understudied but growing segment of the Canadian population, homeschoolers. The purposes of this study were to investigate whether environmental attitudes in Canadian homeschoolers differ from those of people involved with public school and to acquire a greater understanding of the factors that affect the development of these attitudes. The mixed method, follow-up explanatory research design utilized the New Ecological Paradigm Scale and the Connectedness to Nature Scale in an internet survey. The survey was sent to homeschooling and parent groups across Canada. Subsequently, interviews were conducted with a subsample of respondents.
The results of the survey showed that demographic variables were not significantly related to environmental attitude scores with the exception of locale and religion. Urban respondents had slightly stronger environmental attitudes than rural respondents. The confluence of homeschooling and religiosity emerged as the key factor influencing environmental attitudes. There was no significant difference between environmental attitudes of homeschoolers and public schoolers until importance of religion was taken into account. As measured by the scales, religious homeschoolers exhibited the weakest environmental attitudes, public schoolers were in the middle, and not-as-religious homeschoolers had the strongest environmental attitudes. The qualitative data supported these results, with religious homeschoolers expressing weaker
iv
environmental attitudes, particularly in terms of climate change and the need for a more sustainable lifestyle.
Religious homeschooling respondents favoured a more structured back to basics style of schooling which also correlated with lower environmental attitude scores. Unstructured homeschooling respondents tended to choose a child-centred philosophy of education which was correlated with stronger environmental attitudes.
During the interviews, respondents were asked to reflect on what in their lives had influenced their attitudes toward the environment. Consistent with other literature, unstructured outdoor time as a child remained the most significant factor, cited by a majority of respondents. Other important factors included religion, parents, school, teachers, TV/media, economic necessity, and negative experiences with environmental pollution.
The results of this study highlight the importance of considering variables associated with religion when exploring the development or level of environmental attitudes or when conducting a study of homeschooling. Religious beliefs are complex and highly personal in some cases, as is their corresponding influence on environmental concern. Potential exists for environmental concern and action from a group of spiritual people with strong community bonds and often political involvement. The key may be finding common ground and learning to communicate, while resisting expectations of complete agreement. This dissertation showed that stepping outside of the educational system does not necessarily have a direct impact on environmental attitudes, as they are mediated by a complex array of variables. Homeschooling may not directly generate a different level of environmental attitudes than public school; however, religious
v
homeschoolers definitely have a different set of attitudes toward the environment that deserve further in-depth study.

abstract:
Opioid agonist therapy is the gold standard of care for opioid dependence.
However, the efficacy of treatment may be hindered by concurrent drug use, including
cocaine and benzodiazepines. This thesis examines the impact of concurrent drug use on
treatment retention, and whether it is differentially impacted by geographic region. We
conducted a retrospective cohort study using electronic medical records from 58 opioid
agonist therapy clinics in Ontario. One-year treatment retention was the primary outcome
of interest. Both baseline cocaine and benzodiazepine users experienced decreased
retention rates than non-users. Patients who used concurrent drugs at higher frequencies
experienced decreased retention rates compared to those who used less often. Northern
and urban patients were more likely to be baseline cocaine users, and Southern urban
patients were more likely to be benzodiazepine users. Both baseline and continued
concurrent drug use is predictive of treatment drop out in Northern and Southern patients.

subject:

Youth

abstract:
How do children and youth in the classroom impact on the development of student teachers’ classroom management skills during the teaching practicum? This study approached the problem through the sociology of childhood/youth, using a human development framework, and asked children and youth what role they believe they play in the formation of classroom management skills for teaching candidates. Utilizing a phenomenological method, this study sought to discover the perspectives of children and youth, and student teachers themselves, as classroom management developed.
Until now, the role that children and youth play in the development of classroom management for student teachers has largely been ignored. Through a series of observations, focus groups, student teacher questionnaires, and narratives, a portrait emerged of children and youth as active agents in the development of student teachers’ classroom management skills. The key findings indicate that children and youth utilize their agentic status to communicate their needs to student teachers verbally, physically, and through behaviour. A new model of student teaching emerged, suggesting a teaching quadrad where children and youth in the classroom are recognized as playing a role equal to or more significant than that of associate teachers or faculty in the development of classroom management for student teachers.

abstract:
To date, over 400 mineral species have been discovered at Mont Saint-Hilaire (MSH) many of
which are new to science. These new minerals tend to occur as late-stage phases with an
enrichment high field strength elements (HFSE) (i.e. Nb, Ti, Zr) as well as light elements (i.e. Li,
Be and B). Characterization of these minerals has been hindered by their small crystal sizes (i.e.
μm scale) as well as enrichment in light elements. This thesis discusses the chracterization and
overall implications of franconite group minerals as well as the new boro silicate minerals
steedeite and nolzite. Finally the effectiveness of laser ablation ICP-MS as a method of
accurately measuring major concentrations of light elements is discussed.  Franconite group minerals (FGM) are hydrous-alkali niobates, inferred to have formed from Nbrich
precursor minerals at low temperatures (~150 °C). The structures of these minerals are held
together by hydrogen bonds and are highly flexible with Na, Ca, Mg and possilbly Fe2+ and K
substituting for one another. Although FGM are Nb-rich, they are notably devoid of Ta despite
the two elements being geochemical twins. The FGM are crystallo-chemically similar to scandia
octahedral molecular sieves, a group of synthetic compounds known for their cation exchange
properties.  Twelve borosilicate phases, including the new minerals steedeite and nolzeite are known from
MSH. These are crystallo-chemically similar, both minerals containing of single loop-branched
dreier chains in their structures. Such chains occur in synthetic compounds (e.g.
Li2Mg2[Si4O11]) but are not known to occur in other naturally occurring minerals. Steedeite is
highly ordered with respect to Si and B whereas nolzeite contains a mixed Si/B site despite the
two minerals being associated with one another.  Accurate chemical analysis of late-stage minerals, rich in light elements, is hindered by the fact
that such elements have low atomic masses. Laser ablation ICP-MS analysis of a variety of
mienrals with major concentrations of light elements gave measured concentrations of Li, Be and
B that were within ± 10% of expected ideal values for most minerals. Beam widths varying from
6 to 30 μm were employed however; they had no effect on the measured light element
concentrations. Four standards including the NIST610 & 612 glasses, natural beryl, and lithium
metaborate were used. Of these NIST610 is considered the most suitable as it has the smallest
associated errors (1σ error: ± 0.05 to ± 1.68 ppm). Based on this LA-ICP-MS is considered to be
a suitable alternative to secondary ion mass spectrometry for analysis of light elements.

abstract:
Research suggests that, during stress, resilient individuals use positive emotion regulation
strategies and experience a greater number of positive emotions than those who are less resilient.
Therefore, differences could be expected in attentional biases towards emotional stimuli based
on resilience. The current study investigated attentional biases towards neutral, negative and
positive images in response to varying levels of resilence and mood induction conditions
(neutral, negative and positive). Sixty participants viewed a series of pre and post-mood
induction slides in order to measure attentional biases to emotional stimuli. The study provided
evidence for the presence of trait and state congruent attentional biases. More resilient
individuals demonstrated an initial bias towards positive stimuli and once emotion was aroused,
the bias was away from negative stimuli. Additionally, mood congruent attentional biases were
observed for participants induced into positive and negative mood states. Implications as they
apply to research and clinical practice are discussed.

abstract: For many years, scientists have been trying to elucidate the molecular mechanisms that convey pluripotency and self-renewal to stem cells. With this valuable knowledge, they hoped to discover relevant information in the development, growth and regeneration of cells, tissues, and organisms that allow organisms to live as long as they do. These characteristics were once thought to be present only in embryonic stem cells (ESCs), and a few adult multipotent cells such as hematopoietic stem cells (HSCs) and mesenchymal stem cells (MSCs). Recent studies have tapped into the potential of our once thought to be terminally differentiated adult cells to produce self-renewable, pluripotentiating cells, now termed induced pluripotent stem cells (iPSCs). This critical review will discuss the advantages and limitations of the methods developed to generate and characterize iPSCs. Advantages and challenges of the use of iPSCs in applications such as research and therapeutics will also be discussed.

abstract:
There exists a space between the ionosphere and the surface of the earth within which
electromagnetic standing waves, generated by lightning strikes, can resonate around the
earth; these standing waves are known collectively as the Schumann resonances. In the
late 1960s König and Ankermuller already reported striking similarities between these
electromagnetic signals and those recorded from the electroencephalograms (EEG) of
the human brain; both signals exhibit similar characteristics in terms of frequency and
electric and magnetic field intensity. The analyses reported here demonstrate that 1)
microscopic (brain) and macroscopic (earth) representations of natural electromagnetic
fields are conserved spatially, 2) that electric fields recorded from human brains exhibit
strong correlation with the strength of the these parameters and 3) that the human brain
periodically synchronizes with signals generated within the earth-ionosphere waveguide
at frequencies characteristic of the Schumann resonance for periods of about 300 msec.
These findings recapitulate 17th century ideas of harmony amongst the cerebral and
planetary spheres and may provide the means necessary to quantitatively investigate
concepts of early 20th century psychology

Deconstructing the Threshold: A New Architectural Language for the Three Nations Border Crossing confronts the philosophical framework of the international border between Canada
and the United States. By identifying three fictions, following
Peter Eisenman in his essay “The End of the Classical: The End
of the Beginning, the End of the End,” the thesis categorizes the
language of a border crossing into three fictions: Identity (Meaning), Truth (Threshold) and History (Borders through Time). By
understanding these fictions to be the message that Ports of Entry (POE) are designed to convey, how can they be deconstructed, to be read by groups of people who do not acknowledge
the border? The study site and location of a building proposal is
located at the Seaway International Bridge Crossing spanning between Cornwall, Ontario and Rooseveltown, New York. The site
plays an important role in the ideas presented in the thesis as the
site is the location of Akwesasne First Nation, unceded Mohawk
territory which is bisected by this border, reinforcing the idea of
borders as abstract constructs. As borders are not percieved in
the same way by everyone this thesis poses the question - how
can a threshold become a space that embodies the idea of shared

abstract: Previous research manipulated the vision verb within task instructions and examined both response time and P300 differences in response to a stimulus using a within-subject oddball task. Response time and P300 differences between verb categories indicated the possibility of processing differences, however, these results could also have been a result of task switching given the nature a within-subject design. The current research used a between-subject oddball task to control for task switching and measure response time to stimuli following a specific task instruction. Results provide support for the task-switching account.

abstract: Touch DNA is the essence of Locard’s Exchange Principal at a microscopic level – when two objects come into direct contact there is an exchange of materials. Tapelifting has been shown to be the superior method for the collection of touch DNA, in part because it excludes common PCR inhibitors. This study looked into refining the tapelifting method using a modified aluminum stub that is often used in gunshot residue collection or scanning electron microscopy. This stubbing method provides barriers that reduce the risk of contamination, such as the distance between collector and evidence. Substrates that were used for collection included wood, clothing, and writing utensils. In addition, this study looked at a micromanipulation technique that involved the collection of bioparticles using a water-soluble adhesive, while being viewed under a microscope. There were modifications made to the micromanipulation protocol that was outlined by Farash et al. in their paper. One modification was the inclusion of the extraction and quantification steps. PrepFiler Express and PrepFiler Express BTA extraction kits were both used to compare any differences. The PrepFiler Express yielded more results, including the only full profile. The micromanipulation technique and the stubbing method both proved to be adequate methods for the collection of touch DNA.

exposés à des sourires comprenant les caractéristiques d’une sourire authentique
(Duchenne symétrique) ainsi que des sourires sans l’activation du marqueur de Duchenne
et des sourires asymétriques. Les participants doivent déterminer si le sourire est
vraiment joyeux ou non. Tout comme chez les adultes, les résultats révèlent que les
enfants, peu importe leur groupe d’âge, jugent le sourire Duchenne symétrique plus
joyeux que le sourire asymétrique et le sourire asymétrique plus joyeux que le sourire
non-Duchenne. Les participants donnent également la réponse attendue plus souvent pour
le sourire Duchenne symétrique et le sourire non-Duchenne que pour le sourire
asymétrique. Contrairement aux adultes, on ne peut pas exclure l’hypothèse de limites
attentionnelles-perceptuelles chez les enfants, puisque bien que le jugement chez les
enfants s’apparente à celui des adultes, le traitement perceptuel-attentionnel demeure différent.

abstract:
Load-haul-dumps (LHDs) are used to transport materials in underground mining. Due to the
design of LHDs and the design of the mine drifts, these vehicles are implicated in accidents
involving other mining equipment, the mining environment and pedestrians. In 2015, the Ontario
Ministry of Labour published the Mining Health, Safety and Prevention Review, which
recommended that mobile equipment operators need to have a strong situational awareness.
Mindfulness training can be used to improve an individual’s situational awareness and attention.
Mindfulness is a trait that naturally varies amongst individuals. However, it is a technique that
can be taught and with training and practice, a person’s mindfulness levels can improve over
time. There has been limited research conducted in the area of mindfulness and workplace health
and safety; however, there is evidence to suggest that mindfulness training may be a method to
improve workplace safety.
This study measured a person’s inherent mindfulness, attention and situational awareness and
correlated them against driver’s performance measured from within a computer-based virtual
reality underground mine simulator. The simulator, or the Situational Awareness Mining
Simulator (SAMS), provided the virtual reality experience of operating an LHD in an
underground mine. Perception-response time and collisions frequency were measured within the
simulator and used as the measures of driver performance. Situational awareness was measured
within the simulator by questioning the participants about physical aspects of the virtual mine,
such as signage and colour of various objects. Mindfulness was measured using the Mindfulness
Attention Awareness Scale (MAAS) and attention was measured using the Attention-Related
Driving Errors Scale (ARDES-US). Participants (n = 21) operated a load-haul-dump in the simulator for two trials, each
approximately 15-20 minutes in length. Spearman’s correlations showed a relationship between
frequency of collisions and perception-response time (r = .449, p = .05); situational awareness
and collision frequency (r = .507, p < .05); and situational awareness and mindfulness (r = .434,
p < .05). These correlations were present in either Trial 1 or Trial 2, not both trials and thus,
should be interpreted with caution. There was also a significant negative correlation between
MAAS and ARDES-US scores (r = -.516, p = <.05). There were no other correlations present
between ARDES-US scores and any other variables.
This study provides evidence that by cueing individuals to aspects of their surroundings, Level 1
situational awareness (SA) can be increased and further, the relationship between SA and
mindfulness becomes more apparent. No evidence was able to suggest a relationship between
attention levels, as measured by ARDES-US and driving performance, or situational awareness.
The learning curve of adapting to the simulator was substantial, and clouded some of the results,
especially pertaining to collision frequency, and situational awareness.

subject:

abstract:
The increasing threats of global warming, rapid depletion of fossil fuels, and
increasing energy demands are driving an enormous amount of research into clean
renewable sources of energy, flue gas capture technologies, and environmentally friendly
energy storage devices, to name a few. Activated carbons present a multipurpose
material commonly used in many of these increasingly popular green technologies.
A wide range of cross-linked acetylenic polymers of phenylacetylene and 1,3-
diethynylbenzene were synthesized and investigated in this thesis to generate materials
for electrochemical double layer capacitors, CO2 capture, and hydrogen storage.
Chemical activation of the copolymers in the presence of KOH was shown to produce
highly microporous carbons with various textural properties. The specific cross-linking
densities of the polymer precursors prior to carbonization were shown to greatly affect the
carbon yield, surface area, pore volumes and pore sizes of the carbons produced.
Electrochemical measurements of the activated carbons showed their impressive
performances as capacitor materials, with high specific capacitances (up to 446 F g−1 at
0.5 A g−1 in 3-electrode cell) and long cycle life. Gas sorption studies also demonstrated
impressive H2 and CO2 adsorption capacities (up to 2.66 wt% or 13.3 mmol g−1 for H2
adsorption at 77 K and 1 atm, and up to 30.6 wt% or 6.95 mmol g−1 for CO2 adsorption at
273 K and 1 atm).
Owing to the high content of pendent alkyne groups in these polymers,
complexation reactions with metallic carbonyl ligands are able to provide an effective
iv
way of dispersing metallic and metal oxide nanoparticles within the synthesized
copolymers, which could provide additional pseudocapacitive properties. An appropriate
copolymer with high alkyne content was subjected to complexation with Co2(CO)8, and
subsequently carbonized and oxidized to yield carbon-supported CoxOy/Co nanoparticles
(CoxOy@C-CPD76%). In addition to pseudocapacitive contributions, the cobalt species
also effectively catalyzed the production of graphitic networks within the carbon support,
improving their conductive properties. Electrochemical measurements demonstrated
impressive specific capacitance (310 F g−1 at 0.1 A g−1) compared with non-activated
carbons (160 – 177 F g−1 at 0.1 A g−1) synthesized at identical conditions, and provided a
large stable potential window (1.4 V) in an aqueous KOH solution. The combined
electrochemical double layer capacitance and pseudocapactiance behaviour of the carbon
and CoxOy/Co also provided improved energy densities (21 W h kg−1), and
uncompromised power densities (2017 W kg−1) compared with the pristine carbons
(~2034 W kg−1).

abstract:
This work investigates and develops an approach to resolve some of the unique
challenges associated with condition monitoring variable duty equipment. The proposed
solution utilizes the mechanical redundancy of parallel systems to create dynamic
criterion for detecting incipient faults. In this context, parallel systems are those which
contain multiple subsystems (with similar construction) having synchronized operating
conditions. This work evaluates the proposed methodology through its application on
parallel hydraulic gear pumps. By comparing the dynamic pressure and vibration signal
features, it was found that this approach is capable of distinguishing various incipient
failures while the pumps were in both stationary and non-stationary operation.

abstract: The role of microbial communities in the recovery of aquatic ecosystems from watershed disturbance has received little attention despite their important role in energy and nutrient cycling. This study investigates the structure and function of microbial communities on a standardized substrate (alder leaves) in small streams across a wide gradient of watershed disturbances. Microbial communities exhibited variation with disturbance regime with lower hydrolase enzyme activities at all disturbed streams compared to undisturbed streams, and the lowest rates of microbial decomposition, fungal biomass, and differences in microbial community composition at the most severely disturbed streams. Forest and wetland cover were identified as important watershed features that provide DOC to fuel microbial activity in aquatic ecosystems. Increasing road density within the watershed was identified as having a negative impact or association on microbial activity that appeared to be linked to inputs of inorganic solutes that were measured through increased levels of specific conductance in stream water samples. This study is one of the first of its kind and it provides some important evidence that leaf litter associated microbial communities can be influenced by factors linked to watershed disturbance and as such may be useful as indicators of watershed disturbance and potentially the state of recovery of aquatic ecosystems.

title: Gender and personality correlates influence on attitudes towards the elderly in indigenous

subject: gender personality attitudes Indigenous

abstract: Previous literature indicates that there are cultural differences in attitudes towards the elderly; however there are very few if any that examine Indigenous peoples of Canada’s attitudes towards the elderly. The current study aims to understand the influence of gender and personality factors on attitudes towards the elderly. The Kogan’s attitude towards old people scale and Cattell’s 16 Personality Factor measures were used. Results indicated that Indigenous people have positive attitudes towards the elderly. There was no significant difference between genders. Low tension was the only predictive factor for positive attitudes towards the elderly; and vigilance was the only correlated variable with Kogan negative valance items.

subject:
Indigeneity
Indigenous identity
Indigenous culture
colonization
Indigenous reclamation
community participatory research
Sharing Circles
decolonizing methodologies
Indigenous methodologies
Integrated approach to data analysis

abstract:
Much of the research done on, rather than with, Indigenous peoples has led to the
misinterpretation of Indigenous identity by mainstream society and academic researchers. Imagemakers
of early Canadian history put forth misinformation about the “Imaginary Indian,” which
set the basis for how many Canadians and those in academia still view Canada’s national history
(Cronin, 2003; Francis, 1992).
This research sought to understand how Indigenous peoples on the Laurentian University
campus in Sudbury, Ontario defined their own Indigeneity. It is hoped that the results of this
thesis will inform the development of an Indigenous Identity Measure (IIM) as well as reframe
conceptions of Indigenous identities from the viewpoint of Indigenous participants. I employed
Sharing Circles as a community participatory method, with an integrated approach to data
analysis (Bradley, Curry & Devers, 2007; Nabigon, Hagey, Webster & MacKay, 1999). The
purpose of choosing relevant Indigenous methods was to privilege the Indigenous perspective. The Sharing Circles effectively demonstrated the diversity and complexity of how the
participants understood and expressed their Indigenous identity. Culture, Colonization and Selfdetermining
identity, were vital themes to help understanding Indigeneity.
Lastly, by asserting self-determined Indigenous identities and by supporting decolonizing
methodologies, this research can serve as a template to reframe conceptions of Indigenous
identity in the hope that this information might be useful for Indigenous persons, administrators,
researchers and professors on a university campus.

Comment l’architecture peut-elle renforcer l’identité locale du nord aux arénas communautaires
existants par la transformation tout en conservant la mémoire collective déjà présente?
 La notion de lieu est un concept aussi vague que fascinant. Durant ma jeunesse et
jusqu’à ce jour, j’ai été privilégiée de visiter plusieurs endroits grâce au hockey. Sur notre
territoire canadien, certains lieux, et indirectement bâtiments, semblent mériter et recevoir
politiquement et architecturalement plus de respect comparativement à d’autres. Les arénas
communautaires sont importants et représentent le bâtiment le plus fréquenté et utilisé par la
communauté locale dans les petites communautés canadiennes mais souffrent de ce manque
de mérite respectueux. Treize communautés et leurs arénas en bordure de l’autoroute 11
dans le nord-est Ontarien seront visités et analysés selon leurs similitudes et différences pour
conclure avec un seul site choisi par la fin du semestre. Cet aréna sera le premier prototype
né de la recherche élaborée de cette thèse.  Théoriquement parlant, un autre problème émerge avec la typologie des arénas
communautaires; de tels bâtiments ne sont pas classifiés assez nobles pour être considérés
de l’architecture avec un grand ‘A’. Je vais défier cette opinion répandue et rendre
le respect approprié et dû à ces bâtiments en grand besoin de soins, réparations et
rajeunissement pour assurer leur pérénité. Une transformation architecturale sera proposée
afin d’offrir davantage à la communauté. Pourquoi considérer des stratégies de rénovation
versus la construction d’un nouveau bâtiment sera un sujet débattu. La valeur de la mémoire
collective enfermée dans le présent bâtiment sera d’une grande valeur pour ma stratégie.
 Ces petites municipalités ne possèdent aussi aucun, sinon très peu, d’exemples
d’architecture contemporaine publique de qualité. En raison des contraintes de l’économie
locale et du très petit bassin de taxes municipales dans le nord, les nouveaux bâtiments
civiques requièrent souvent accès à l’aide des autres paliers gouvernementaux. Cela équivaut
souvent à une réplique d’un modèle comprenant une structure en acier préfabriquée conçue
dans le sud ontarien afin de minimiser les coûts. En gros, la notion d’identité, de mémoire
collective, de régionalisme et même de développement durable dans tous ses aspects est
ignorée. Mon projet va annuler l’option d’un nouvel aréna selon les normes que permet le
financement gouvernemental afin de considérer et incorporer ces notions si importantes. La
question du lieu en toute sa grandeur sera explorée car ce simple concept déterminera une
méthodologie, des justifications et un design reflétant le style et les intérêts locaux, avec des
ressources locales pour l’économie locale.

abstract:
From the assembly of intricate biomolecules to the construction of tissues and
organs from homogenous embryonic cells, patterns permeate throughout biological
systems. Whereas molecules govern the multiform signalling pathways necessary to
direct anatomy and physiology, biophysical correlates are inextricably paired to each and
every chemical reaction – yielding a constant interplay between matter and energy.
Electromagnetic energies represented as propagating photons or electromagnetic fields
have shown to contain complex information that is specific to their paired molecular
events. The central aim of this thesis was to determine whether these biophysical
signatures or patterns can be obtained from biomolecules and subsequently be used in
lieu of the chemical itself within a molecular cascade to elicit desired effects within biological systems. The findings presented here show that using a novel bioinformatics
tool, namely the Cosic Resonant Recognition Model (RRM), biomolecules (proteins) can
recognize their particular targets and vice versa by dynamic electromagnetic resonance.
We also show using fundamental units of energies that this dynamic electromagnetic
resonance is within the visible spectrum and can be used to define molecular pathways
such as the ERK-MAP pathway, or distinctive viral proteins that mark certain pathogens
such as Zika or Ebola viruses. Further findings presented herein show that these
electromagnetic patterns derived from biomolecules can be detected using modern technologies such as photomultiplier tubes, and as every signature is unique to that
system, can be used to identify insidious systems such as cancers from healthy
populations. Furthermore, it is now possible to capture these unique electromagnetic
signatures of biomolecules, parse the signals from the noise, and re-apply these patterns back onto systems to elicit effects such as altered proliferation rates of cancers or
regenerative systems. The series of theoretical models and investigations outlined here
clearly profiles the predominant electronic nature of the living matrix and its constituents,
which lays the groundwork for reshaping our knowledge of cellular mechanisms that
ultimately drive physiology, medicine and the development of effective diagnostic,
preventative or therapeutic tools.

abstract:
The Miller Dyke Complex (MDC) is located 15 km south of the Kirkland Lake gold camp. It
consists of a series of narrow, structurally controlled dykes, that range from felsic to mafic in
composition, and are spatially associated with Au, ± Cu, ± Mo mineralisation. The MDC provides
an excellent locality for a careful study of the igneous petrology and the different alteration
assemblages associated with the mineralisation. The study is focused on the metasomatic
processes related with alkali elements. It is shown that strong sodic alteration has a strong
influence on the textural, mineralogical, and geochemical features of these rocks. Previously
undescribed textures and mineralisation styles are documented, as well as the existence of a
Paleoproterozoic hydrothermal reactivation event with metal deposition or remobilisation. The
relationship between the alkali metasomatism and gold mineralisation is discussed within the
regional context of the Abitibi greenstone belt.

Depuis des milliers d’années, les hommes font la guerre; celle-ci s’est transformée
selon les aléas techniques et politiques de l’évolution de la société. Aujourd’hui, les
militaires canadiens participent à plusieurs missions, dans le cadre de ses diverses
alliances et pour diverses raisons : maintien de la paix, protection du pays, des valeurs,
etc. La guerre engendre des conséquences physiques importantes, mais il en est aussi
d’ordre psychologiques. Ces conséquences psychologiques se nomment blessure de
stress opérationnel (BSO). Notre recherche de type qualitatif consiste à identifier, du
point de vue du service social et au-delà des services et programmes déjà mis en places
par les Forces armées canadiennes (FAC), les besoins des militaires souffrant de
blessure de stress opérationnel au retour de missions, ainsi que les besoins spécifiques
des familles de ces militaires.
La population type de notre recherche est composée de militaires canadiens qui ont
été déployés dans le cadre de missions étrangères et qui ont souffert ou qui souffrent
d’une BSO. Notre échantillon est composé de neuf militaires; cinq hommes actifs, une
femme active et trois vétérans, huit vivaient en couple, tous âgés de quarante à cinquante
ans, tous bilingues et tous membres du rang (non commissionné). La collecte de données
a procédé à partir d’entrevue semi-dirigée appelée aussi semi-structurée. Les données de
cette recherche montrent qu’il y a plusieurs dimensions des programmes d’aide et de
soutien qui doivent être améliorés de manière à permettre aux Forces armée canadienne
de répondre plus adéquatement aux besoins spécifiques des militaires souffrants de BSO
au retour d’une mission, ainsi qu’aux besoins de leurs familles, et ce, au-delà des
améliorations que les FAC ont déjà apportés aux programmes lors de ces dernières
années.

title: Synthesis and characterization of novel ethylene copolymers by palladium-diimine catalysts

subject:
Novel ethylene copolymers
Palladium-diimine catalysts

abstract:
Late transition metal catalysts, especially Pd-diimine catalysts, have been
extensive studied for olefin polymerization. The unique characteristics of Pd–diimine
catalysts, including chain walking mechanism, highly electrophilic cationic metal center
with reduced oxophilicity, the capability of initiating and catalyzing olefin "living"
polymerization, and the sterically tunable–diimine ligands, allow the synthesis of a
range of polyolefins and olefin copolymers with special pedant functionalities and
unique microstructures. The main objective of this thesis research is to synthesize
different new types of polymers and polymer-grafted nanoparticles with Pd–diimine
catalysts by utilizing above unique characteristics.
A broad class of low-polydispersity ethylene–norbornene (E–NB) copolymers
having various controllable comonomer composition distributions, including gradient,
alternating, diblock, triblock, and block-gradient, was synthesized through
“living”/quasi-living E–NB copolymerization facilitated with a single Pd–diimine
catalyst. This synthesis benefits from two remarkable features of the Pd–diimine catalyst,
its high capability in NB incorporation and high versatility in rendering E–NB “living”
copolymerization at various NB feed concentrations ([NB]0) while under an ethylene
pressure of 1 atm and at 15 C.
A class of hyperbranched polyethylene ionomers containing positively charged
tetralkylammonium ions and different counter anions were first synthesized by direct
iv
one-pot copolymerization of ethylene with tetralkylammonium-containing acrylate-type
ionic liquid comonomers. The use of a Pd–diimine catalyst, which shows excellent
stability towards the highly polar ionic group, is key to the direct synthesis. The
resulting ionomers properties including structural, thermal, and melt rheological
properties have also been demonstrated.
In a further study, HBPE ionomers encapsulating self-supported Pd(0)
nanoparticles (NPs) as efficient and recyclable supported Pd catalysts were synthesized
with a Pd–diimine catalyst. The Pd(0) NPs were immobilized on the ionomer matrix
through ionic interaction directly during the copolymerization of ethylene with
polymerizable ionic liquid comonomer. The resulting ionomer supported Pd(0)
nanocatalysts have been utilized to catalyze carbon-carbon cross coupling reactions
(Suzuki and Heck reactions) and semi-hydrogenation of alkynes.
Moreover, the successful tuning of structural parameters of PE brushes in
surface-initiated ethylene “living” polymerization from two types of silica nanoparticles
were studied. The brush parameters that are controlled herein include brush length,
density, and topology. The PE-grafted silicas with varying brush density and length are
also used as nanofillers to construct polymer nanocomposites with an elastomeric
ethylene-olefin copolymer (EOC) as the matrix polymer. The effects of brush length and
density on the nanofiller dispersion, rheological properties, and tensile properties of the
composites are examined (The preparation and characterization of the nanocomposites
were carried out by K. Petrie and M. Kontopoulou at Queen’s University).

abstract:
The “millennial” has become a prominent term in today’s society and culture.
“millennials” refers to a generation of young adults born between the early
1980s and 2000.1
 Made up of over 92 million people this generation is larger
than the Baby Boomers2
, and have a huge influence on the world’s economy,
social policies, culture, and urban fabric. As of 2018, the millennial generation
will have an annual spending of 3.39 trillion dollars, surpassing the Baby
Boomer generation in buying power.3
 However, millennials have inherited a
different circumstance from the previous generation, dramatically changing
the social, cultural, and economic needs of the millennials. Challenges such
as climate change, the housing bubble, and an inflated economy, influence
the possibilities of future home ownership for this generation. Additionally, the
element of technology is intertwined with the day-to-day of millennials. How
might technology manifest itself within architecture of the future? And how will
architecture adapt to suit the needs and desires of the upcoming generation?
