abstract:
In order to examine the effects of soil temperature on a coupled photosynthesis-stomatal
conductance model, seedlings of trembling aspen (Populus tremuloides Michx),
jack pine (Pinsu banksiana Lamb. ), black spruce (Picea Mariana (Mill) B.S.P.) and
white spruce {Picea glauca (Moench) Voss.) were grown over a wide range of soil
temperatures from 5 °C to 35 “C. Temperature, light and CO2 response curves of foliar
gas exchange were measured four months after the start of the treatment. The results
showed that the four boreal tree species had very similar cardinal soil temperatures for
key model parameters (i.e., Vcmax, Jmax). The key parameters of the model showed dual
soil temperature symmetry; below-ground and above-ground temperature symmetry, and
low and high temperature symmetry. In the below-ground and above-ground
temperature symmetry, the key model parameters responded to soil temperature in a
similar manner as to leaf temperature. For low and high soil temperature symmetry, the
symmetry was not perfect, with steeper slope at the higher-than-optimum temperature
range, which indicated the photosynthetic machinery of the four boreal trees was
suppressed more at high soil temperatures than at low soil temperatures.
The effects of soil temperature on key model parameters were modeled using
three different equations. Three equations fitted the measured key model parameters
well, but only the bio-chemical equation showed a specific pattern for the equation
parameters between the four species. Soil temperature had no effects on R^, the daytime
respiration that continues in light. It was speculated that after four months of soil
temperature treatments, the four boreal tree species acclimated to different soil
temperature conditions by optimizing allocation of nitrogen investment into different
functional photosynthetic components and balancing water use efficiency and nitrogen
use efficiency.

abstract:
This thesis is an examination of the commercial product MYKE which is a perlite-peat mixture containing 7 spores/g of Glomus intraradices N.C Schenk & G.S. Sm., a vesicular-arbuscular mycorrhiza-forming fungus.
Seeds of American elm (Ulmus americana L.) were aseptically geminated and forty seedlings planted in Erlenmeyer flasks containing a vermiculite-peat mixture (10:1) and supplemented with different amounts of MYKE. Ten flasks received no MYKE, ten flasks received 1 gram, ten flasks received 5 grams, and ten flasks received 25 grams. All flasks were incubated under fluorescent white lights for 3 months at 25°C. When seedlings were harvested, they were grouped according to treatment and photographed, then bagged, dried and weighed. A representative seedling from each group was stained with Trypan Blue. Results revealed that no spores had germinated as there was a lack of mycelium in the flasks and no colonization of the roots had occurred. It was found that increasing the amount of MYKE per flask caused a reduction in seedling growth. It was hypothesized that several factors may have resulted in lack of spore germination such as low light intensity affecting seedling growth and subsequently affecting quantity and quality of root exudates that would normally stimulate spores to germinate. The results of this experiment do not negate the potential benefits of vesicular-arbuscular mycorrhiza-forming fungi, especially in the urban landscape.


title: Are individuals able to accurately report their own behaviour? An investigation of observer-respondent disparity of reported behaviours associated with social anxiety?

subject:
Social anxiety
Mental disorders

Self-awareness

abstract: Social anxiety is characterized by the powerful fear of negative evaluation from others and a high level of self-focused attention (SFA). In addition, socially anxious individuals often engage in a variety of anxiety-related behaviours during a social situation. The purpose of the current investigation was to analyze the relationships between social anxiety, SFA, and anxiety-related behaviours and to assess the observer-respondent disparity in reports of anxiety-related behaviours. This study assessed 104 students from Lakehead University who were asked to complete a battery of self-report questionnaires and then partook in a social anxiety induction where they were asked to speak about themselves to two individuals during a video-conference. The participants were instructed to provide their best first-impression and were advised that the individuals they will be speaking to were instructed to only listen. The sessions were videotaped to permit observer ratings of the participant’s anxiety-related behaviour. Hierarchical regression analyses were executed to analyze the relationships among the different variables and a positive relationship was found between both social anxiety and SFA with safety behaviours. Additionally, a positive relationship was found between only social anxiety and the non-verbal behaviours measured with an established ethogram. Self-report ratings were then compared to the observer ratings and the results indicated that low and high levels of social anxiety were associated with under and overestimations of anxiety-related behaviour use, respectively. A similar pattern of results was found for reported SFA level. The findings from this study suggest that reliance on self-reported behaviour may not be the most accurate method of assessing behaviours associated with social anxiety, as individuals with high levels of social anxiety may not be able to accurately report their own behaviours.


title: Electroconvulsive shock-induced amnesia: an investigation of the reinstatement effect

subject: Amnesia Memory

abstract: Three experiments were conducted to investigate the reinstatement effect, in which amnesia has been reported following the pairing of a noncontingent footshock and ECS. In experiment I the possibility that a FS-ECS combination is more effective than a single ECS at disrupting memory consolidation was examined. Rats trained on a passive avoidance task which received ECS 15 seconds after training showed a partial amnesia. A noncontingent footshock preceding ECS at 15 seconds did not augment this amnesia but rather attenuated it, providing no support for a consolidation interpretation of the reinstatement effect.

abstract:
This research will critically examine the difference in data quality and
accessibility between two cities through an analysis of predicting the effect of
impervious surfaces on water quality. Through using the Impervious Surface Analysis
Tool (ISAT) provided by the NOAA Office for Coastal Management, a basic analysis will
be completed to compare data quality, accessibility and the application of the data.
The results of the analysis indicate that insufficient data quality hinders the
understanding of effects of impervious surfaces on water quality. Thus, showing the
requirement for producing and providing high quality data in Canada to allow water
resource managers to make appropriate decisions to mitigate, minimize or avoid
impacts on the local hydrology of the area.

abstract:
Introduction: As stroke continues to be the leading cause of adult disability, understanding the
rehabilitative needs of those affected is essential to ensure they are receiving proper care to reach
their own sense of independence. This is particularly important for those living in cities such as
Thunder Bay where there is a lack of resources and services. As seen in the literature, mainly
quantitative measures have been used to gather information about stroke survivors’ experiences.
Through a qualitative lens, only surveys have been used; therefore, using semi-structured
interviews allows participants to share their experiences by being able to expand on their
thoughts. As there has been little research in Thunder Bay regarding stroke survivors’
experiences, there is a need to speak with these individuals to fill this gap in the literature.

Culturally safe Indigenous midwifery

abstract:
In recent years, Indigenous midwifery has reemerged as a vital form of maternity care in Canada.
With the majority of practices being situated in rural and remote areas, Seventh Generation Midwives
Toronto (SGMT) remains the only urban-based Indigenous focused midwifery practice in the country.
Looking to develop a culturally relevant performance measurement system for the practice, SGMT
partnered with the Well Living House (WLH) – an Indigenous action research centre in Toronto – to
undertake a community-based, participatory, realist, and utilization-focused evaluation study. This thesis
project was nested in one of the qualitative branches of this evaluation. Semi-structured interviews were
conducted with nine former clients of SGMT who self-identified as Indigenous to determine (1) how
Indigenous women conceptualize cultural safety and (2) the extent to which their experiences at SGMT
aligned with these conceptualizations. The interviews were transcribed verbatim, and the transcripts were
analyzed using collaborative, consensus-based, iterative, and decolonizing methods. Twelve core themes
that were grouped into four thematic pillars or containers emerged from this process. Even though the
women participants were unique in their backgrounds, insights, and experiences, when taken together,
culturally safe Indigenous midwifery care meant (1) "culturally continuous care”, (2) being able to access
both Indigenous knowledge and practice and practical reproductive health information, (3) being
connected to the community, and (4) feeling “at home” in a health care setting. There was also
widespread support for SGMT as a practice; most – although not all – women felt that their pregnancy,
birthing, and reproductive needs were fully met, and that they were made to feel culturally safe. All of the
women offered constructive and loving feedback for the practice, even if they had experiences that fell
short of their expectations. This confirms that SGMT can and does provide culturally safe care, and that
cultural safety both has benefits and a place in the mainstream health care system. This project also sheds
light on the roles and responsibilities of contemporary Indigenous midwives and the ways in which they
can be supported. Altogether, herein lies a compelling argument for the continued support and expansion
of urban-based Indigenous midwifery, and the application of cultural safety in a Canadian context.


title: Can complex adaptive systems theory contribute to understanding attachment injuries in adult relationships? A qualitative approach

subject:
Adult attachment
Attachment injuries

abstract:
Researchers have discovered that the world is composed of panarchies of complex adaptive systems. This
approach acknowledges the existence of non-linear relationships and emerging patterns among nested
systems. Systems exist on varying interacting scales including at the level of the individual, among groups,
societies and ecologies. Complexity theorists have identified a four-phased process, the adaptive cycle,
which can help us understand how complex adaptive systems change. The adaptive cycle typically involves
the system shifting from initial growth, to increased structure and efficiency at the cost of resilience,
followed by shock, release, and reorganization. This process has been identified in various types of systems
and across disciplines, but complexity theory has not informed understanding of couple dynamics or the
processing of attachment injuries. Attachment injuries are critical moments in close relationships that can
influence how we view ourselves, others, and the world. In Study 1, 15 community members spoke about
their lived experience with attachment injuries. In Study 2, eight participants familiar with complexity
theory shared their views on the connections between complexity and couple relationships. The two groups
recruited reflect an effort to explore attachment and complexity from two unique angles. The studies were
conducted in parallel, rather than sequentially. A qualitative approach was identified as most appropriate
since this intersection in research has not been explored. Data analysis was iterative, conceptually- and data-driven, and informed by thematic analysis, in order to identify emerging themes. Study 1 themes were: (a)
context of injury, (b) impact of injury, (c) impact on and role of beliefs, (d) attachment processes, and (e)
release and reorganization. Study 2 themes included: (a) uncertainty, and (b) perceived positives of adopting
a complexity lens. Conceptualizing relationships and attachment as complex systems, directions for future
research, and considerations for psychologists, are discussed.


title: Dawn of discovery : Margaret Atwood's Morning in the burned house

abstract:
Morning in the Burned House, Margaret Atwood's new
collection of lyric poetry, is a carefully structured exploration
of the spiritual dimension of selfhood. The volume is divided
into five sections which each serve as "stages" of awareness, and
the poetry is ordered in such a way that the sections themselves
and the volume as a whole both convey a sense of progressive
development. This thesis examines the interdependent structure of
Atwood's volume, tracing the gradual increase in perception which
ultimately leads to a conscious recognition of spirituality.
Chapter one, "Now there are more of me," is an exploration
of the first two sections of the collection. These poems
initially focus on the individual self, and present a series of
recollected losses. The loss of an individual spiritual self,
however, moves the poems to a questioning of morals, thereby
transferring the focus away from self to the other. My analysis
involves the perceived relationship between self and other, and
also the function of these opening sections as a structural
foundation in the volume.
Chapter two, "Now look objectively," examines the
transitional nature of the third section. I evaluate physical
existence as the focal point through which these poems first
explore the social and mortal aspects of self through the other,
thereby leading to a consideration of the possibility of a
spiritual existence.

subject:

Molecular dynamics

abstract:
Dielectric relaxation studies of a series of polar diaryl molecules and of some analogous rigid molecules dispersed in atactic polystyrene and poly(vinyltoluene) have been carried out. Preparation of both polymer matrices and the dielectric measurements using a General Radio 1615-A capacitance bridge and a Hewlett-Packard Q-meter with appropriate temperature-controllable cells have been described.
The experimental data as a function of frequency at different temperatures
were subjected to analysis by a series of computer programmes written
in the APL language. The activation energy barriers for the dielectric
relaxation processes were obtained by the application of the Eyring rate
equation.
A number of polar rigid molecules has been studied to provide a wide background knowledge of relaxation and activation parameters for
comparison with those of flexible molecules of analogous size. Attempts
have also been made to correlate the molecular relaxation absorptions by
classification of the polar rigid molecules into three categories in terms of their dipole positions. It is apparent from the present study that the inclination of the molecular dipole to the principal axes may be a factor in determining the magnitude of the observed relaxation time and the activation parameters and this is in line with what was previously found by investigations in the liquid state. To this end. studies have been made of some disc-llke molecules such as 9-bromoanthracene and 9-bromophenanthrene. Comparison of their Eyring analysis results with the other elongated molecules showed that the molecules exhibited different contributions for rotation about the principal axes...

subject: Resource-based tourism

abstract:
The landscape of northern Ontario provides an ideal setting for resource-based
tourism and, in recent years, the focus on tourism has increased due to the
popularity of outdoor recreation and the notion that tourism can increase
community sustainability. Resource-based tourism is based on a wide range of
activities which are both consumptive and non-consumptive. As an industry,
tourism can have significant impacts on natural, physical or social environments
and it is important that the industry be managed sustainably. Currently, there is no
generally accepted approach for examining the sustainability of the resource-based
tourism industry and ensuring that resources are managed in the interests of future
generations. The international forestry and tourism industries have adopted the
concept of sustainability indicators. Their initiatives provide guidance for the
development of a regional framework for resource-based tourism. Through a
workshop and mail survey, members of the Northern Ontario Tourism Outfitters
Association (NOTO) identified values that they believe are essential to the
sustainability of resource-based tourism. This input, combined with data collected
through a literature review, was utilized to develop a suite of indicators of
sustainable resource-based tourism. An evaluation of each indicator was conducted
and a revised framework of 23 indicators reflecting on ecological, economic and
social values is presented. The framework will be useful to resource managers and
the tourism industry.


title: Position control of a quadrotor UAV using stereo computer vision

subject:
Quadrotor dynamics
Unmanned aerial vehicles

abstract:
Quadrotors are a recent popular consumer product, prompting further developments with regards
to combining attitude and position control for such unmanned aerial vehicles (UAVs). The
quadrotor’s attitude (orientation) can be controlled using measurements from small and inexpensive
sensors such as gyroscopes, accelerometers, and magnetometers combined in a complementary
filter.
The quadrotor’s position can be controlled using a global positioning system (GPS); this has
shown to be an effective method but is not reliable in urban or indoor environments where quadrotors
may be flown. An alternative method such as visual servoing may provide reliable position
control in urban environments. Visual servoing uses one or more on-board cameras to detect
visual features in their field-of-view. If more than one camera is used, a more accurate position
can be determined.
This work discusses the the application of stereo visual servoing to a quadrotor for position control
combined in a Kalman filter with IMU readings to provide a better estimate of its position.


title: Changes in winter habitat use by mammals following commercial thinning of lodgepole pine (Pinus contorta) in west central Alberta

subject: Lodgepole pine thinning (Environmental aspects, Alberta)

subject: Mammals wintering

subject: Mammals Habitat Alberta

abstract:
In 1996, Millar Western Forest Products initiated an adaptive management experiment to assess the potential benefits of commercial thinning and to monitor its effects on winter habitat use by multiple mammalian species, using indirect evidence (snow tracking). This program was known as the Commercial Thinning Winter Tracking Project (CTWTP). Track surveys are well suited to investigate habitat use, because transects can be restricted to specific habitat types and individual tracks can often indicate behaviour based on gait, movement pattern and other signs associated with the tracks. Differences in the frequency of track occurrence among habitat types can also indicate habitat preference. The CTWTP surveyed mammal track occurrence over 7 years on 30 transects within the 1695 ha Tom Hill study site southwest of Whitecourt, Alberta. Transects were located in one of four forest types: aspen dominated, black spruce dominated, reference lodgepole pine, and treatment (thinned) lodgepole pine. ANOVA and Tukey post-hoc tests were used to identify differences in mammal track occurrence among the three unthinned forest types and between the reference and treatment pine forest types. Moose and weasels were most common in black spruce. Snowshoe hare were most common in reference lodgepole pine. White-tailed deer and marten were more
common in aspen. Fisher, rodents, lynx and coyote appear to have no preference for any
of the three unthinned forest types. Comparisons between reference and thinned pine
forest types identified three groups of species. Fisher and snowshoe hare appear to have
decreased after thinning. Weasels, white-tailed deer and marten track occurrence
increased after thinning. Species that do not appear to have been affected by the thinning
were moose, rodents, squirrels, lynx and coyote. Principal Components Analysis (PCA)
was used to identify correlations between track occurrence and habitat variables (i.e.
snow depth, temperature).PCA identified positive and negative associations with a
variety of habitat characteristics that may underlie the observed differences in track
occurrence. Additional investigation focused on the ecology of more specific clades of
wildlife and collection of track data at a variety of spatial scales may be a way of taking
this broader summary of the CTWTP to a finer investigation ofhabitat use in the Tom
Hill study site.


title: Factors associated with depressive symptoms in long-haul truck drivers: a cross-sectional study

subject:
Depression (long-haul truck drivers)
Truck driving & mental health

abstract:
Many North Americans are affected by mental health disorders (MHD) each year [1,2].
One of the most common MHDs is major depression [1,2]. Major depression has many costs for
the individual and the economy [3–5]. Those with depression are more likely to experience
difficulties sleeping, chronic fatigue, poor physical health, and are at risk of committing suicide
when compared to non-depressed individuals [1,6,7]. The overall risk of mortality is higher
among those with depression than those without [5]. On the economic level, depression is
associated with an increased number of missed days at work (absenteeism) and poor productivity
at work (presenteeism) [5]. Depression is estimated to cost the U.S. economy $36.6 billion per
year in lost worker productivity [5].
Certain occupations put individuals at greater risk for depression than others. One of
these occupations includes long-haul truck drivers. The risk of depression in trucking is higher
when compared to at least 19 other occupational types [1,2,8–11]. Long-haul truck driving
involves delivering freight to distant locations [12,13]. Truckers are usually on the road for
several days at a time [14]. Many also drive overnight and are often alone during their shifts and
their work breaks [14,15]. They also experience tight delivery timeliness and are often paid
based on how far they drive, or how much freight they can deliver [13,16]. The working
conditions of long-haul truckers can result in feels of social isolation and can lead to poor sleep
and fatigue [14,15,17]. Many truckers have also reported that they experience stress due to tight
and unrealistic delivery deadlines, poor road conditions, and violence at work [16].

abstract: Vertical jump height is a method of assessing muscle strength and power in the lower body, and is used to assess athletic ability. The gold standard in measuring vertical jump height is the measurement of the vertical centre of mass (COM) displacement from three-dimensional (3D) video analysis. Vertical jump height is ultimately affected by takeoff COM velocity, as greater takeoff velocity results in greater jump height. The current study explored the use of takeoff versus maximum COM velocity by examining the relationships and differences between 3D video analysis and 3D force platform analysis when predicting vertical COM displacement. Use of the Vertec, and correction of takeoff COM velocity using takeoff posiion, was explored through methods proposed by Aragon-Vargas (2000) and Moir (2008).

title: A review and evaluation of growth response, stand value and profitability of pre-commercially thinned Jack pine stands in Northwestern Ontario

subject:
Pre-commercial thinning
Tree growth response
Lumber recovery
Total stand volume

abstract:
This thesis will be a literature review with the purpose of evaluating the impact precommercial thinning (PCT) has on the tree growth response and if it can meet the
objective of profitability in Jack pine (Pinus banksiana Lamb.) stands in Northwestern
Ontario. Timing and thinning intensity have been identified as two major factors which
influence the success of PCT. A general conclusion that can be made from the literature
reviewed is that there is no specific threshold for timing and thinning intensities. Both
are dependent upon the management objective and success can only be attained when
used properly. If the goal is to achieve high-quality logs, then applying PCT at a low
intensity and later in the stand’s development will help meet this goal. However, if the
goal is to produce high volume with the shortest rotation age, then applying PCT at a
high intensity at an early stage in the stand’s development will yield positive results.
Additionally, tree growth response is clearly impacted by PCT. Greater thinning
intensities can cause rapid diameter growth at the cost of increasing the abundance of
more severe defects and reduce the overall quality of wood. When applied appropriately,
PCT was found to decrease the total stand volume however, it can increase the total
merchantable volume. Furthermore, it was estimated that in some cases, PCT can
produce approximately $2,880 more average lumber recovery per hectare when
compared to control stands. From the literature reviewed, it appears that PCT can meet
the objective of profitability in Jack pine stands in Northwestern Ontario when used
correctly.


title: Inuit visions for schooling in one Nunavut community

abstract:
This descriptive case study explores Inuit visions for schooling in a remote community in
the Qikiqtani (formerly Baffin) Region of Nunavut. I use information from interviews, casual
conversations, observations, and a review of the literature on minority and cross-cultural
education to describe what participants want, to discuss obstacles to student learning, and to
suggest ways to improve schooling in Nunavut. The study, conducted in a critical frame
foregrounding issues of power, was meant to be useful in considering change. Data came
primarily from semi-structured interviews with 74 Inuit adults, and were contextualized by two
years of teaching grade 7 in this community in the late 1990s, five short visits since, master’s
research in five communities in the Kivalliq Region of Nunavut, four months of fieldwork in
2006, and two brief trips to return preliminary findings to the community.
Findings from this study echo descriptions of what Inuit participants want from schooling
found in the Sivuniksamut Ilinniarniq consultations (Aylward, 2004) and the Nunavut Education
Act consultations (Nunavut Department of Education, 2006). Participants supported schooling
and wanted an increase in Inuit knowledge and skills taught in (and outside) of the schools. They
wanted an increase in, or strengthening of, Inuktitut in the schools, the meaningful inclusion of
elders in schools, and higher academic standards. These wishes were consistent for women and
men, younger and older participants, the wage-employed and those without wage employment,
highschool graduates and those without formal schooling, and for participants who take part in
‘traditional’ activities like hunting, sewing and carving, as well as for those who do not.
Participants described a number of obstacles to student achievement, and no one theory
can explain the failings of Nunavut schools. Many concerns identified in the literature on schools
that underserve Aboriginal and minority students are discussed. These include culturally
incongruent pedagogy, a weak connection between school and work, prejudice from non-Inuit,
and disempowering relations between the school system and the community. Eurocentric thinking
in the schools, the school system, and in Canada continues to block the creation of schools that
work for Inuit.
The Government of Canada must provide funding to facilitate the transformation of schooling in Nunavut to a system based in Inuit culture. The Nunavut Department of Education
must work with Inuit educators to implement the changes called for in the Bilingual Education
Strategy. As long as non-Inuit educators are needed in Nunavut, District Education Authorities
should prioritize the hiring of people who are willing to examine their own Eurocentrism. In
calling for schools where Inuit language and culture are taken seriously, people in Tuktulik
reassert that despite massive pressure for assimilation, assimilation is not inevitable. It is time for
EuroCanadians to understand this message.

subject: Site index (Forestry) Ontario Thunder Bay (Ont. : District)

abstract:
Site index of natural jack pine (Pinus banksiana Lamb.) in the Thunder Bay area was related to features of soil and topography using multiple regression analyses. Site index (SI, height of jack pine trees at 50 years from breast height) was used as the dependent variable and 129 soil and topographic variables were considered for the analyses. Due to
problems associated with numerous independent variables, multicollinearity, and highly variable soil groups, the four preliminary regression equations computed from 95 plots could not be accepted as valid equations. The final analyses limited the number of independent variables considered for analyses and landform types were more precisely defined. The "best"
final regression equations explain 83, 65, 65, and 75 percent of the variation in SI for bedrock, morainal, glaciofluvial, and lacustrine landforms, respectively. The variables included in the bedrock equation are depth to bedrock (DBR), and coarse fragment content of the A horizon
(CFRAGA). The variables included in the moraine equation are depth to a restricting layer (DRL), percent clay in the A horizon (CLA), and coarse fragment content of the C horizon (CFRAGC). The variables included in the glaciofluvial equation are depth to a moist restricting layer (DMRL), and percent slope (SLOPE). The variables included in the lacustrine
equation are thickness of the A horizon (THA), and pH of the BC horizon (PHBC). The final regression equations for bedrock, moraine, and glaciofluvial sites predict SI reasonably well for 15 check plots.

abstract:
The Barrick Gold owned Hemlo Au deposit is a world class Archean Au deposit situated
in Northern Ontario, Canada with historic production of >21 Moz of Au over 32 years of
continuous operation. The deposit has a strike length of ~3 km with a well-documented alteration
footprint surrounding mineralization. Laser ablation inductively coupled plasma mass
spectrometry (LA-ICP-MS) analyses of epidote, chlorite and pyrite from within and surrounding
the Hemlo gold deposit have identified major and trace element variations in mineral chemistry
that allow for the discrimination of deposit-proximal and deposit-distal signatures. Short wave
infrared (SWIR) analysis of epidote and chlorite from around the Hemlo deposit can discriminate
between end-member compositions of epidote and chlorite and is a useful tool for interpreting
mineral paragenesis.
Epidote varies in chemistry surrounding the deposit with the highest concentrations of As
and Sb proximal to the mineralized zones and can be detected at anomalous values up to 1.5 km
further than the documented deposit footprint. Using LA-ICP-MS, As and Sb can be detected at
significantly higher concentrations (more than an order of magnitude) within epidote than in
traditional whole rock geochemistry, allowing for better targeting of the deposit footprint.
Chlorite also displayed variation in trace elements with deposit-proximal chlorite displaying
exponentially higher Ti/Sr and V/Co values than deposit-distal and intrusion-related chlorite. The
Ti/Sr ratio for chlorite expanded the geochemical footprint of the Hemlo deposit by up to 1 km.
Pyrite displayed anomalous enrichments in a number of elements, including Au, Ag, As, Sb, Bi,
Te, Mo and W, that could be detected at elevated concentrations proximal to the deposit. Gold,
Te and As proved to be the most effective pathfinder elements in pyrite as they were detected at anomalous concentrations up to 2.5 km from the deposit and were detectable in pyrite at much
greater concentrations relative to whole rock geochemistry.
Several syn-to post-tectonic intrusions that surround the deposit were evaluated using
epidote and chlorite chemistry for their potential to create false positive anomalies for
mineralization. The distal intrusions of interest displayed no distinctive variation in epidote or
chlorite chemistry and did not display false positive anomalies. Intrusion related epidote contain
consistently low As and Sb levels relative to deposit epidote was also displays elevated Fe/Al
values. Intrusion related chlorite displayed low Ti/Sr and V/Co values relative to the deposit
chlorite and was also found to be more enriched in Fe relative to deposit-proximal chlorite.

Efficient procurement and optimal utilization of woody biomass for bioenergy production requires a good understanding of biomass supply-chain management. The general objective of this research is to develop decision support models for analyzing and aiding decision-making for optimal woody biomass supply chain management for energy production in northwestern Ontario (NWO). The specific objectives are: exploration of data sources and methods for assessing woody biomass availability, assessment of availability of woody biomass feedstock for energy production in the forest management units (FMUs) of NWO; development of a road network optimization model to optimize woody biomass feedstock transportation from forest cells (1 km x 1 km grid) to power plants; and development of optimization models for analyzing the optimal woody biomass supply from forest cells to one power plant with monthly production schedules (dynamic mathematical programming model) and to four competing power plants (modeling the woody biomass competition issues) in NWO.
The spatial assessment study found that in the 19,315 depletion cells (the forest areas where some level of timber harvest took place during 2002-2009) within the study area about 2.1 million green tonnes (gt) of forest harvest residue and 7.6 million gt of underutilized wood are technically available, which is enough to supply the annual biomass demand (2.21 million gt) of the four power plants were they to convert to using only renewable energy sources.


title: Validity of the K-Bit and a WISC-III short form with a sample of adolescent young offenders

subject: Juvenile delinquents Intelligence testing

subject: Kaufman Brief Intelligence Test

abstract:
The present study investigated the concurrent validity and testretest
reliability of the Kaufman Brief Intelligence Test (K-BIT; Kaufman &
Kaufman, 1990) by comparing it to the full scale administration of the
Wechsler Intelligence Scale for Children third edition (WISC-III; Wechsler,
1991) in a clinical trial with 35 young offenders. Using a test-retest
methodology, the concurrent validity of a four subtest short form of the
WISC-III (SF4) was also assessed.
Results of this study show that while the K-BIT is a reliable
measure, it did not perform well in terms of validity criteria typically
applied to short form estimates of intelligence. While mean Full Scale IQ
(FSIQ) and Performance IQ (PIQ) were not significantly different, the KBIT
overestimated Verbal IQ (VIQ) by an average of five points.
Correlation coefficients between the K-BIT and WISC-III were significant
but not impressive and only 40% to 50% of the IQ estimates were within
WISC-III 95% confidence limits. Qn the other hand, SF4 performed
reasonably well as an estimate of FSIQ, with a high correlation
coefficient and a low misclassification rate. When administered first SF4
overestimated FSIQ by three IQ points, however when administered
following the full scale, SF4 overestimated FSIQ by six IQ points.


title: Tool for measuring self-preserved "pressure" in athletes

Athletes

abstract:
The purpose of this study was to develop a practical assessment
tool for measuring self-perceived "pressure", a situational
variant in athletes. A checklist was developed and in its final
form contained 16 items. The checklist was shown to be a valid,
reliable, readable, and standardized assessment tool. Responses
to the scale used in the checklist were weighted to reflect
the levels of both positive (facilitatory) or negative (inhibitory)
effects of internal and external sources of pressure. The
developed checklist was administered to four Olympic athletes
during competitions and provoked honest, accurate responding
while demonstrating the sensitivity to "pressure". The checklist was shown to be capable of providing immediate feedback to
coaches concerning athletes' perceptions of pressure prior to
performance. The checklist provides scores which can be quickly
interpreted by the coach as a measure of the levels and sources
of pressure perceived by athletes.

Boost converter control system

abstract:
In this thesis, a robust controller comprising of a PI with phase-lead compensator for a DC-DC boost converter designed using classical frequency response method is presented. The superior performance of this controller in comparison with H[symbol] and passivity based integral controllers from the literature is shown. The robustness of the controller to boost converter parameter deviations, disturbance magnitudes and polarity which lead to worst case stability is investigated. This approach offers an alternative to the traditional unstructured uncertainty envelop approach used in the literature.
Investigation into the nonlinearity arising from parasitic parameters in a boost converter is also presented in this thesis. It is shown that this nonlinearity can cause instability in boost converter control. This nonlinearity makes robust controller design difficult due to the sensitivity to disturbances. Static and dynamic voltage collapses are then studied. New non-iterative formulae are derived using the bilinear averaged model to calculate the voltage collapse point due to the parasitic parameters. Using these simple formulae boost converter stable operating region and disturbance limits can be calculated in the design phase. The use of these formulae for the design of the boost converter control system is studied. Static characteristics formula and the proposed controller performance are verified experimentally.

Depression and eating disorders

abstract:
Attentional biases and extreme attitudes have been linked to schematic functioning and
development in depression and eating disorders. Previous research concerning attentional biases
toward schema-congruent material in depression and eating disorders has, for the most part,
focused on negatively valenced emotion and body weight/shape material, respectively. The
present study employed a stimulus word list, comprised of 52 words that was compiled from
Brittlebank, Scott, Williams, and Terrier (2003), and Cassin and von Ranson (2005) to assess
extreme attitudes toward schema congruent material. The sample was comprised of 60 female
high school students who participated in the video series Turning Points for Teens: Ontario
Community-Based Treatment for Adolescent Eating D isorders (Davis et al., 2004), as well as
209 female university students. Participants rated each word according to valence (i.e., '’very
positive” to ''very negative”). These valence ratings, in combination with measures of body
image and eating concerns, affect, depression, and self-esteem were employed to explore the
evocative nature of schema-congruent material. Hierarchical multiple regressions indicated that
there was a relationship between scores on the Eating Disorder Examination Questionnaire
(EDE-Q), body mass index (BMI) and the valence and extremity ascribed to body-related
stimuli. In contrast, scores on the PANAS Positive Affect Scale were related to the valence
ratings ascribed to affect-related words. Furthermore, self-esteem acted as a moderating factor in
the relationships between the scores reported on the psychometric measures and the ascribed
word valence ratings. Lastly, comparison of pre- and post-intervention scores indicated that
participants reported significant reductions in eating and body image concerns, and rated Thin
Body stimuli more moderately following participation in the Turning Points program.


title: Loneliness and disclosure to peers by early adolescents

subject:
Loneliness in children
Self-disclosure

abstract:
The present research was designed to investigate the
differences between lonely and non-lonely early adolescents
in: (a) their disclosures to familiar peers and, (b) their
perceptions of their relations with familiar peers. In the study,
sixty-nine early adolescents completed the Asher Loneliness
Questionnaire (Asher et al., 1984). A sub-sample of males
and females who were lonely and non-lonely were engaged
in dyadic conversations. The subjects were required to
complete pre-conversation and post-conversation ratings of:
(a) liking of partner, (b) perceived liking by partner, (c)
familiarity of partner, and (d) perceived familiarity by partner.
As expected, same-sex patterns emerged with respect to
familiarity and perceived familiarity. Although not
hypothesized, same-sex patterns of liking and perceived
liking were also found. It was expected that there would be
differences between lonely and non-lonely early adolescents
in their disclosures to peers as a function of sex. While
differences between the disclosures of lonely and non-lonely
subjects were found, these were not a function of sex but of
partner’s loneliness. Specifically, it was found that lonely
male subjects disclosed less intimate information to lonely
than non-lonely partners. Non-lonely male subjects did not
differentially disclose to lonely and non-lonely partners. Lonely female subjects disclosed relatively high-intimate
information to both lonely and non-lonely partners compared
to non-lonely female subjects. As expected, lonely subjects
reported that they were less liked by partners than did nonlonely
subjects. The implications for clinical work and peer
relations are discussed as well as possible limitations of the
study.

Northwestern Ontario

abstract:
In order to foster the future economic growth of Northwestern Ontario, cooperation and
partnership with key groups are necessary. This exploratory case study identifies new economic trends in industry, focusing on partnerships involving Aboriginal and non-Aboriginal participants in business. The purpose of the study is to determine Northwestern Ontario’s readiness to engage in authentic partnerships. Several major themes came to light as a result of the research. These themes include: changing demographics in Northwestern Ontario; legal structure and framework of partnerships; duty to consult; an operationalized definition of authentic partnership; examples of successful partnerships and reasons for success; important leadership characteristics in partnership; critical success factors for partnership; outcomes of partnerships; examples of unsuccessful partnerships and lessons learned; future opportunities;
possible solutions and methods to encourage sustainable authentic partnership leadership. Further, the critical success factors for building and sustaining authentic partnership appear to align with the Seven Grandfather Teachings, with the element of “time” as a moderator. This study contributes to an existing, but limited, body of research by providing practical solutions to assist parties in establishing successful authentic partnerships and by answering the question of Northwestern Ontario’s readiness to engage in partnership. Further research recommendations include a more thorough review of the Seven Grandfather Teachings with a  focus on one specific case study. With additional work in this area, it is possible that participants to a partnership will not regress in their ability to create authentic partnerships and not repeat the mistakes of the past. The benefit of authentic partnerships between Aboriginal and nonAboriginal groups is the ability to move forward and to share in social, economic and relationship success.

Time-dependent polarization

Nylon filament

abstract:
The experiments described in this work are divided into two main
parts. The first is concerned with electrical properties of a
single filament of nylon held between two tungsten hook-electrodes.
Currents were observed in atmospheres of different relative humidities and attempts were made to determine the voltage distribution
along the filament. The voltage measurements were made using
a high-impedence electrostatic null detector with a potentiometer
system for balancing. The results were not highly reproducible
and no definite conclusions could be made.
The second part deals with currents through capacitor tissue in a
metal- insulation- metal sandwich arrangement. A time-dependent
polarization was observed and is discussed along with methods for
determining an acceptable value for the steady-state current. Some
attempts are made to apply Poole-Frenkel theory since there is a
certain quantitative agreement with experiment. Current-temperature
observations indicated that the activation energy is about 1 ev.
Conclusions concerning the mechanism of conduction are suggested on
the basis of available theory.


title: Study of zonation at the Nanisivik Zn-Pb-Ag mine, Baffin Island, Canada

subject: Mineralogy Northwest Territories Nanisivik Mine

abstract:
Zn-Pb-Ag mineralization at Nanisivik, northwest
Baffin Island, is hosted by Proterozoic, laminated dolostone
of the Society Cliffs Formation. Mineralization of the Main
Orebody is highly variable in terms of texture and mineralogy
exhibiting both replacement and open space filling textures.
Sulfides are generally coarsely crystalline and banding,
consisting of interlayered pyrite, sphalerite, galena and
sparry dolomite, is common along the margins of the Upper
Lens of the Main Orebody. The eastern and central portions
of the Upper Lens are characterized by laterally extensive
mine units, which are distinguished on the basis of texture
and mineralogy. Contacts between units are generally sharp.
The physical and chemical parameters responsible for
the textural and mineralogical variations have been evaluated
through a study of fluid inclusions, sulfur isotopes and ore
mineralogy. Fluid inclusion homogenization temperatures from
simple, two-phase primary and pseudo-secondary inclusions in
sphalerite and sparry dolomite gangue indicate initial
temperatures of ore formation from 150—210 degrees C in the eastern
Upper Lens when the estimated pressure of ore formation is
taken into consideration- The temperature of ore formation
decreased to 100-150 degrees C in the western portion of the Upper
Lens.  Freezing studies indicate that the ore-forming fluid was a brine containing 20-37 equivalent weight percent CaCl[subscript] 2,
The sulfur isotopic compositions of late and main stage
pyrite crystals range from [symbol]S = +27.4%. to + 28.0%., suggesting
relatively constant temperature, fluid source and
dominant sulfur species in the ore fluid during ore formation,
providing there has been no subsequent re-equilibriation of sulfur isotopes. The iron content of sphalerite
varies from 14 mole % to 0 mole % from crystal centers to
rims respectively, corresponding to well developed colour
zonation. Sphalerite iron contents constrain the oxygen
activity of the ore fluid from 10[superscript -46] to 10[superscript -41] at 200°C during sphalerite precipitation. The best developed zoning and,
thus, the highest oxygen activities occur within sphalerite adjacent to carbonate wall rock. Under high oxygen
activities, conditions were favorable for the generation of
sulfanes considered necessary for precipitation of marcasite.
X-ray diffraction studies indicate that primary marcasite has
inverted completely to pyrite. The stability of the simplest
sulfane, H[subscript 2] S[subscript 2] constrains the maximum allowable pH of the ore fluid at the time of marcasite precipitation to 5.0. The
presence of interbanded marcasite pseudomorphs and sparry
dolomite indicate that the ore fluid fluctuated around pH = 5.0.
Comparison of solid organics extracted from the
Society Cliffs dolostone to bitumen associated with mineralization suggests that organics within the host formation have
played a role in sulfate reduction. The model of ore formation
therefore proposed involves the in situ reduction of a
hot, saline, metal-bearing ore fluid by hydrocarbons
liberated by the replacement and dissolution of wall rock.
Sulfate reduction was probably concentrated at the wall rock
orebody interface along a replacement front that migrated
away from the orebody. Banding was likely the result of
repetitive sulfate reduction, metal precipitation and wall
rock dissolution in response to the pulsatory influx of ore fluid. Gross textural and mineraiogical variations are
probably a result of slight variations in the oxidation state
of the ore fluid, the availability of H[subscript 2] S and, to a lesser
extent, temperature.

title: Dietary restraint : the role of causal attributions

subject:
Food consumption

Appetite

abstract:
Previous studies have indicated that restrained and unrestrained eaters
exhibit dififerent eating patterns in response to preloading or no preloading. After
a preload, restrained eaters tend to exhibit counterregulatory behaviour, where
they consume more and unrestrained eaters tend to exhibit normal regulatory
behaviour, where they consume less. The present study was designed to examine
vsdiether these patterns are due to different attributional styles exhibited by
restrained and unrestrained eaters. In Phase 1, undergraduates enrolled in
Introductory Psychology were administered the Restraint Scale, the Beck
Depression Inventory, and the Eating Attributional Style Questionnaire. It was
hypothesized that restrained eaters would attribute Mure to maintain dietary
restraint in hypothetical situations to internal, stable, and global causes which are
associated with the abstinence violation effect (AVE). Contrary to expectations.
Mure to maintain restraint was attributed to external and global causes. For
Phase 2, 100 female subjects were selected fi*om the above pool of subjects based
on their scores on the questionnaires. Using a matching procedure, subjects were
randomly assigned to one oftwo conditions: preload or no preload. In both
conditions, subjects' cookie consunq)tion was measured in a taste test. The results,
using a median split analysis, indicated that an external orientation to food
consunq)tion was a better predictor ofthe preloading effect than the dimension of
restraint.


title: Adaptive time-step control algorithm for nonlinear time-domain envelope transient

subject:
Electric circuits (Automatic control)
Differential equations
Control theory

abstract:
This thesis outlines a general method to analyze circuits with several time variables using
a technique known as Multi Partial Differential Equation, MPDE. The key idea of MPDE is
to convert the system of ordinary differential equations that describes a circuit into a system
of partial differential equations using multiple time dimensions. Multivariate Finite Difference
Time Domain (MFDTD) and Time Domain Envelope following (TD-ENV) methods are based
on the MPDE and give faster simulation time and reduce the memory requirements for a system
with widely separated time scales.
In this research, a novel time-step control method in one of the time dimensions is proposed.
The algorithm uses two models: the first is the set of differential algebraic equations that
represent the circuit. The second is a ‘coarse’ model that is cheap to evaluate. The main
difference between the traditional and the proposed method is the dynamic tolerance changes
and coarse model representation. The optimum time step is estimated from an error term
obtained from the coarse model. An estimation of the Local Truncation Error (LTE) is used to
optimize the time step size. The simulations show that fewer time steps are rejected, i.e. faster
computation, compared with a traditional time step control algorithm.
A rectifier circuit is simulated to show the difference between the conventional method and
the MFDTD method for steady state analysis. The MFDTD method is used in steady state
analysis and the TD-ENV method is used in transient simulations. A DC-DC converter circuit
simulation using adaptive TD-ENV and its advantages are presented. Simulations of a switched
rectifier circuit and DC-DC converter circuit with different controllers (P and PI) are presented.
The PI controller circuit experiences a duty cycle oscillation and higher LTE, which increases
the simulation time with the proposed model. The FDTD method is used to solve the problem
in one of the dimensions (fast time axis) and the Backward Euler (BE) method is used on the
other dimension (slow time axis).


title: Predicting alcoholism treatment outcome

subject:
Alcoholism (Treatment)
Prediction (Psychology)

abstract:
The detrimental effects of alcoholism on society have stimulated
the growth of addiction treatment centers. These programs are
characterized by low completion rates. This fact has promoted a
great deal of research aimed toward predicting treatment
completion. If those "at risk" for dropping out of programs can
be identified, they can be singled out for special consideration
which could result in their success with treatment.
Alternatively, if it can be determined that clients with certain
characteristics have a high probability of completing treatment
at specific centers, then patient characteristics can be
"matched" with the program shown to offer such people the best
opportunity for treatment completion. The majority of studies
in this area have used MMPI scales and/or combinations of
demographic variables for prediction. In general, these studies
have not been very successful or have failed to replicate. Some
reasons for this are small sample sizes, a limited number of
variables used in prediction, and lack of cross validation. The
present research addresses these problems by using large numbers
of subjects and predictor variables. Cross validation was
performed on an independent sample. Phase One subjects were
drawn from archival records; a sample of three hundred and
seventy subjects was obtained; two hundred were treatment
completers and one hundred seventy non completers. Variables
included in the analysis were; age, sex, race, education. marital status, nnuummbbeerr of dependents, employment status,
previous treatments, weeks sober prior to treatment, place of
residence, prescription medication, referring agent, self
reported reasons for referral, and the three validity and ten
standard clinical scales of the MMPI, Through discriminant
analysis, an overall successful classification rate of 65.4% was
obtained. Treatment completers were classified correctly 74.0%
and non completers 55.3%. The cross validation sample was
obtained and variables collected in the same manner as in phase
one. Data from one hundred treatment completers and eighty non
completers was collected. The discriminant function from phase
one derived an overall successful classification rate of 56.1%.
Treatment completers were classified correctly 69.0% and non
completers 40.0%. Results highlight a dramatic failure to
predict treatment dropouts. However, treatment completers could
be predicted. The relevance of this finding for treatment
matching was discussed. It was concluded that, due to the
heterogeneity of alcoholic samples, personality measures such as
the MMPI should only be used to describe population
characteristics at specific treatment centers; generalization
should not be expected. It was hypothesized that, by looking
for specific predictors at each treatment center instead of
searching for global predictors, treatment matching is feasible,
and may be very helpful in reducing dropout rates.

abstract: This study explored evidence of a change in students' attitude towards mathematics in junior classes through the use of a mathematically-based stories unit. Using a questionnaire, observations, interviews, and classroom audiotapes, a pre- and post- design was used with the implementation of the unit. Attitude did not change quantitatively according to the questionnaire results, but there was a postitive reaction by participants, as noted during the interviews, to the mathematically-based stories unit. A small sample size and limited choice in teacher volunteers are possible limitations to the results. A longitudinal study using the same elements might produce more definitive results.


title: A knowledge-based approach for semantic similarity, relatedness, and word sense disambiguation using WordNet

contributor:
Benlamri, Rachid
Khoury, Richard

abstract:
Various applications in computational linguistics and artificial intelligence rely on
high-performing semantic similarity and word sense disambiguation techniques to solve
challenging tasks such as information retrieval, machine translation, question answering,
and document clustering. While text comprehension is intuitive for humans, machines
face tremendous challenges in processing and interpreting a human’s natural language.
This thesis discusses two interconnected natural language processing tasks using a contextual semantic approach and knowledge-based repository. The first task is a knowledgebased semantic similarity and relatedness between words using WordNet, and the second
is a knowledge-based semantic word sense disambiguation. The semantic similarity and
relatedness task determines the level of likeness and connectedness between two words
within a given context based on their semantic representation within a knowledge graph.
The word sense disambiguation task determines the correct sense (meaning) of a word
within sentence and document contexts.
The main focus of current research in this field relies solely on the taxonomic relation
”ISA” to evaluate semantic similarity and relatedness between terms. Semantic similarity and relatedness have not been exploited to their full potential to solve integral natural
language processing tasks, such as the word sense disambiguation task. Despite the wide
range of knowledge-based word sense disambiguation approaches, the underlying similarity measure for most of them is the word overlap measure (i.e., Lesk similarity measure),
which is, by definition, limited to the exact match of terms between the compared texts.
This thesis explores the benefits of using all types of non-taxonomic relations in WordNet
knowledge graph to enhance existing semantic similarity and relatedness measures. We
propose a holistic poly-relational approach based on a new relational-based information
content and non-taxonomic-based weighted paths to devise a comprehensive semantic
similarity and relatedness measure. Furthermore, we propose a novel knowledge-based
word sense disambiguation algorithm, namely Sequential Contextual Similarity Matrix
Multiplication algorithm (SCSMM). The SCSMM algorithm combines semantic similarity, heuristic knowledge, and document context to respectively exploit the merits of local context between consecutive terms, human knowledge about terms, and a document’s
main topic in disambiguating terms. Unlike other algorithms, the SCSMM algorithm
guarantees the capture of the maximum sentence context while maintaining the terms’
order within the sentence. Also, we identify the core factors that affect our proposed
algorithm and most existing word sense disambiguation systems.
The results of the proposed algorithms demonstrate an improvement over the benchmark methods, including the state-of-the-art knowledge-based techniques. Our proposed
semantic similarity and relatedness measure demonstrated improvement gain that ranged
from 3.8%-23.8%, 1.3%-18.3%, 31.8%-117.2%, and 19.1%-111.1%, on all gold standard
datasets MC, RG, WordSim, and Mturk, respectively. On the other hand, the proposed
SCSMM algorithm outperformed all other algorithms when disambiguating nouns on the
combined gold standard datasets, while demonstrating comparable results to current stateof-the-art word sense disambiguation systems when dealing with each dataset separately.
Finally, the thesis discusses the impact of granularity level, ambiguity rate, sentence size,
and part of speech distribution on the performance of the proposed algorithm.

A food system is a set of interrelated functions that includes food production,

populations, and food recycling, composting, and disposal (Dahlberg, 1993; Cornell
University, n.d.; Community Food Security Coalition, 2009). Food systems are dynamic
and complex, and reflect unique social, cultural, environmental, and economic factors and
circumstance. For the better part of human history, most people ate food that was
produced and distributed within local food systems (Xuereb, 2005). However, in the last
several decades, there has been an increasing trend toward industrialization and
globalization, and the subsequent concentration of ownership and control of food systems
around the world (Koc & Dahlberg, 1999; Heffernan & Hendrickson, 2005; La Trobe &

abstract: Electrokinetics is a promising technique to prevent / minimize the migration of pollutants to the soil and/or groundwater and to remediate contaminated slurries. Electrokinetics requires a low-level direct current (dc) between an anode and a cathode. This results in electro-osmosis, electro-migration and electrophoresis along with electrolysis reactions. An electrokinetic barrier utilizes electro-osmosis, electro-migration and a soil zone with high pH created near the cathode to prevent the migration of contaminants. Electrophoresis accelerates the sedimentation of contaminated slurry whereas electro-osmosis and electro-migration remove water and pollutants from the slurry.

abstract:
Vibration control is very important in many areas including machine operation and
daily life. Semi-active vibration control integrates a tuning control scheme with a tunable
vibration absorber for suppression of vibration due to a harmonic excitation with a
variable excitation frequency.
The electromagnetic vibration absorber (EMVA) is a semi-active vibration device
whose stiffness can be tuned on-line. In this study, the EM VA is used for non-collocated
vibration control. The study consists of two parts. In the first part, the characterization of
the EMVA is revisited using a commercial FE package, Comsol Multiphysics. Various
single physics models are built including the electromagnetic coil, the electromagnetic
coil with a core, and a permanent magnet (PM) placed between a pair of PMs. These
models are used to study the magnetic density in the gap of the electromagnet. A
coupling model that involves magnetism and structural mechanics is built. This model is
used to study the factors that affect the magnetic stiffness.
In the second part, the EMVA is implemented to suppress vibration of a structure that
can be modeled as a three-degree-of-freedom system. The non-collocated control theory
is reviewed. The EM VA is modified to allow both manual adjustment and on-line tuning.
Three different control methods, FFT-based method, FFT-based plus fine tuning method,
and RM S-based method, are developed. The experimental results using the three methods
are compared.

subject: Armillaria trapping

subject: Armillaria root rot China

subject: Armillaria root rot Ontario, Northwestern

subject: Artificial regeneration

subject: Plantation management

subject: Root rot distribution

abstract:
Methods for detecting and evaluating Armillaria in plantations were compared in a series
of studies. The purposes of the studies were to standardize the Armillaria trapping technique,
and to determine if it could be used in practical forest management to monitor and evaluate
Armillaria root rot hazard in plantations. Trapping involves burying a removable substrate in
the soil for infection by rhizomorphs (RMs). The fungus reacts to the trap by rapidly colonizing
the substrate. The distribution of Armillaria is then inferred from the locations of infected
traps.
In a study of entrapment methods, spruce [Picea sp.) and poplar [Populus sp.) trap logs
were compared with each other and with mesh bags filled with conifer bark. Potato tuber
(Solarium tuberosum) traps were unsuccessful. Bark bags were the most successful traps in
terms of sensitivity, clarity of infection, and ease of interpretation, but they were more difficult
to prepare and install than trap logs. Both species of trap logs detected similar levels of Armillaria
prevalence. However, the spruce logs were generally easier to evaluate. Some inconsistencies
in detection may be resolved by further refinements in trap preparation.
In a study of young plantations on recent cutovers and one undisturbed, mature spruce
stand, estimates of the distribution of Armillaria based on various indicators were compared.
Trap logs detected Armillaria in all plots including the mature spruce plot which was mossy and
water-logged. The percentages of plot area subjected to Armillaria impact were estimated to be
3-21% using dead trees, 16-54% using residual stand material, and 12-69% using positive trap
logs. A comparison of these estimates showed that Armillaria RMs were much more prevalent
than was indicated by the dead planted trees. These estimates plus a survey of healthy and
infected trees showed that stump presence alone was a poor indicator of potential damage from
Armillaria root rot. Mortality surveys were used to augment the trap results. Although current
levels of mortality were high (4.8% spruce, 3.6% Larix sp.), it was suggested that the trees may
have been predisposed to Armillaria attack by stresses such as root deformity.
To determine the utility of the trapping technique by forest managers unfamiliar with it,
the trap bag technique was introduced to a forest management unit in northeastern China. The
traps tested in a Pinus koraiensis plantation were superior to soil samples for evaluating the
presence of viable RMs. Persons with little or no experience in identifying Armillaria learned to
recognize the fresh, abundant RMs quickly and confidently.
It was concluded that the trap methods described can be used at the management level,
but that they should be used in association with sound advice regarding the role of Armillaria
in overall plantation health.

abstract:
Traditional approaches to timber management planning do not
address the realities of catastrophic wildfire. The model
FORMAN is one of the operational wood supply models used in
Ontario for forest regulation. The FORTRAN program
FORMANB.FOR, presented here, incorporates the subprogram
BURN.FOR, that models continuous wildfire according to
historical patterns. Incorporating the risk of forest fire
on the Nakina Forest lowered the sustainable harvest level
from 520,000 m3/year to 473,500 m3/year (9%).
When choosing the sustainable harvest level in light of
this, the forest manager must evaluate options within a
larger timber supply context. The ability to consider risk
of fire explicitly as part a wood supply analysis should
increase the forest manager's confidence in long-term
timber supply projections and short-term harvest levels.

The White Pine Fork Mo porphyry has an estimated resource of 16 Mt of Mo at 0.1%
Mo. The host intrusions are K-feldspar- and quartz-porphyritic monzo- to syeno-granites
characterised by LREE enrichment, fractionated HREEs and negative Nb, Ta, Sr and Ti
anomalies, consistent with a subarc mantle melt source. The granites also have an adakitic
geochemical signature. A U-Pb age for zircon from a clast in the mineralized breccia pipe at
White Pine yielded an age of 26.52±0.42 Ma, which falls within the error of the White Pine
intrusion age of 26.61±0.24 Ma. Re-Os ages for duplicate samples of the Mo-mineralised quartz
breccia are 30.21±0.14 and 29.84±0.15 Ma, which correlate with the age of the Little
Cottonwood stock rather than the host intrusion and may represent Re-Os inheritance. In
contrast, Buckingham Mo (-Cu) porphyry has an estimated resource of 1,000 Mt of Mo at 0.1%
Mo and is hosted in Cretaceous K-feldspar- and quartz-porphyritic granites. Four feldspar- and
quartz-porphyritic granites in the area were dated using LA-ICP-MS U-Pb of zircon and yielded
ages of 38.68±0.53, 39.28±0.58, 40.76±0.41, and 40.81±0.51 Ma and therefore unrelated to the
Buckingham deposit, and instead are correlated with Tertiary magmatism associated with Au
skarns in the nearby Battle Mountain district. The Tertiary intrusions are feldspar- and quartz
porphyritic granites. Primitive mantle-normalized geochemistry of both suites of intrusive rocks
have LREE enrichment, fractionated HREE, negative Nb, Ta and Ti anomalies and a slight
enrichment of Zr and Hf, consistent with a subarc mantle source for both suites.
The most prominent alteration in both systems is phyllic alteration comprising an
assemblage of white micas, quartz and pyrite. Potassic alteration was also observed at the White
Pine Fork Mo breccia pipe and kaolinite and chlorite observed in SWIR data suggest advanced
argillic alteration around the Buckingham system. These petrographic observations are substantiated by the whole rock geochemistry. The potassic, phyllic, and possible advanced
argillic alteration were mapped out by the absolute values of trace elements. The trace element
geochemistry of quartz and pyrite can be used to fingerprint deposit types and as vectors towards
mineralisation in alteration systems around ore deposits. At White Pine Fork, the hydrothermal
quartz is characterised by higher Ti and As than the igneous quartz. The Li content of
hydrothermal quartz is greater near the centre of the White Pine Fork deposit than in its margins.
At Buckingham, quartz in the breccia cement at the centre of the deposit shows the highest
concentration of Al, Li, K, Ca, As, and Sb, and metals (i.e. Cu, Fe, Zn, and Pb), whereas the
igneous and sedimentary quartz shows the highest Ti values. The high values indicate that the
primary Ti contents were not subjected to recalibration during hydrothermal alteration. The Al
and Sb contents of quartz decrease away from the centre of deposit at Buckingham. This trend
was not observed at White Pine Fork.

subject: Mental health

abstract:
Dialectical behaviour therapy (DBT) is a psychological treatment developed for
individuals experiencing significant mental health issues along with high-risk behaviours (e.g.,
suicidal behaviours, self-harm, substance use, aggression, impulsivity). Despite substantial
evidence supporting its use, many DBT programs have problems with sustainability, which
leaves individuals with severe mental health issues without the treatment they need. The goals of
the current study were to: a) identify factors that impact the functioning of DBT programs in
Thunder Bay, Ontario; b) identify factors that are particularly relevant for youth DBT programs;
c) make recommendations to foster the facilitators of success and address the barriers that hinder
the functioning of DBT programs. Clinicians (N=31) trained in DBT completed a semistructured
interview exploring their experiences providing DBT and thoughts on the factors that
facilitate or hinder the functioning of the DBT programs. The interviews were transcribed
verbatim and then organized into themes using inductive thematic analysis. Three major themes
emerged as barriers to the functioning of DBT programs: systemic challenges, conflicts within
the consultation teams, and clinician burnout. Factors influencing the success of DBT programs
included: systemic support, clinician commitment and “buy in,” and team cohesion. Unique
factors specific to providing DBT with youth (i.e., level of commitment, simplifying the
language, and parental investment) were also identified. The findings provide novel information
on barriers that impact the functioning of DBT programs from clinicians’ perspectives within a
Canadian publically funded mental health system. These findings have clear clinical utility and
can be used to generate solutions to clinicians’ perceived barriers and to foster perceived
facilitators.


title: Childhood adversity and functional impairment in emerging adulthood: the role of executive function

subject:
Emerging adulthood
Adverse Childhood Experiences (ACEs)

abstract:
Emerging adulthood (EA; ages 18-29) is a unique developmental period when individuals
transition from their teenage years into adulthood, experiencing increased demands associated
with independence. For some, there are increased levels of uncertainty and mental health
difficulties, but, for those who adapt to such transitions, there are positive implications in later
life. Adverse childhood experiences (ACEs) may potentiate transitional difficulties in EA.
ACEs are known to disrupt neurodevelopment and executive function (EF), a key set of mental
skills that include emotion regulation and planning. As such, emerging adults who experience
ACEs may be at an increased risk for impairment during these important transitional years.
This study examines whether ACEs are related to decreases in EF and functional impairment in
emerging adults. Specifically, Hayes’ PROCESS macro is used to test whether the relationship
between ACEs and functional impairment was moderated by EF. A total of 162 emerging
adults completed an online self-report questionnaire package assessing ACEs, EF, and
functional impairment. As expected, regression analyses highlighted that number of endorsed
ACEs significantly predict self-reported EF scores in emerging adults. Similarly, ACEs predict
self-reported functional impairment in the domains of school, family, life skills, risky
behaviours, self-concept and social relationships. However, EF did not significantly moderate
the relationship between ACEs and functional impairment, contrary to expectation. Upon
further investigation, exploratory mediational analyses demonstrated that EF significantly
mediates the relationship between ACEs and functional impairment such that EF partially
explains the relationship between ACEs and functional impairment in emerging adults. The
present results demonstrate the need to consider EF as a target to reduce functional impairment
in emerging adults.


title: Development of optimal breeding zones for white spruce in Ontario under current, past, and anticipated future climate change / by Ashley Marie Thomson.

subject: White spruce - Breeding

subject: Climatic changes - Environmental aspects

subject: Forest productivity

subject: Tree improvement

subject: Ontario

abstract:
Tree breeding zones are delimited areas where trees are selected and bred, and their progeny are planted. Within these zones, the level of adaptation between seedlings and planting sites is controlled to ensure adequate survival and growth. Delineation of adaptively-based zones requires detailed knowledge of patterns of genetic variation within species.
Five-year height, root-collar diameter, current increment and survival were
measured at each of six Ontario white spruce provenance trials containing 127 sources from across Ontario and western Quebec. Survival generally did not demonstrate significant variation amongst provenances, except at the Englehart test site, while the remaining three traits were significant at most sites. Intraclass correlation coefficients for significant traits ranged from 0.7% for elongation at the Englehart site to 19.2% for survival at the Englehart site. Growth data from 2007 were combined with 2002-2004
growth and phonological data. Principal components analysis was used to summarize the main components of variation, explaining a total of 53.8% of the total variation with the first three axes. The first principal component represented mainly growth potential, while the second and third represented field trial phenology and greenhouse timing, respectively. Multiple linear regressions revealed significant correlations to both temperature and precipitation variables, explaining 28%, 53%, and 27% o f the total
variation in the first three principal components axes. Regression equations were used to map predicted performance of white spruce across the study area of Ontario.
The focal point seed zone procedure (FPSZ) was used to determine areas of adaptive similarity for each of 618 gridpoints across Ontario based on current climate. These areas were used to represent candidate breeding zones constructed at levels of +/- 1.0 and +/- 0.5 least significance difference values. A maximal-covering model was then used to determine the optimal combination of a specified number of zones that could be
used to maximize the area covered by breeding zones. Thirteen breeding zones were required to cover the entire range of white spruce in Ontario at the 1.0 LSD level of adaptive similarity, while more than 40 zones were required at the 0.5 LSD level. The northwest and northeast forest management regions could be covered with 6 breeding zones at the 1.0 LSD level and the southern region with just 5 zones.
The analysis was repeated using simulated past climate data from the CGCM2, HADCM3, and CSIRO climate models as input to the procedure. The HADCM3 model produced optimal breeding zones that were most similar to those developed for the current climate and is probably most reliable for predicting climate in Ontario. Future climate data for the same 3 models based on the A1 and B2 emissions scenarios was used to predict the location of future breeding zones for each of the six future climate
scenarios. The HADCM3 model predicted the location of future zones to be relatively similar to those based on current climate, while CSIRO predicted wide shifts in the location of future zone boundaries and CGCM2 predicted moderate shifts.

subject: Bacteria - Effect of ultraviolet radiation on

abstract:
The optical dose in mJ/cm[superscript]2 for causing mortality of Escherichia coli, using wavelengths between 230-375 nm in the UV and 400-532 nm in the mid-visible spectral regions,  has been determined in
this study.   Currently, the mercury 254 nm UV line or    UV flash lamp sources are used in most optical equipment designed for bactericidal action. However, little is known about the bactericidal effect of UV at longer than 254 nm and visible light radiation between 400-532 nm.  An accurate knowledge of the   bactericidal dose versus wavelength is of central importance in the optimal choice of   light source for a given application.  Now that UV diodes and lasers emitting  in the 280 to 340 nm range are entering the developmental phase, they can be added to the list of
existing UV flash lamps, discharge lamps and high intensity visible lasers for use in bactericidal applications.
E. coli cell suspensions at about 1x10[superscript]8 CFU/ml were exposed to various  dosages of radiation
between 230-532 nm and the survival cell densities were determined by drop-plating.  Radiation between 260 to 280 nm in the UV region was most efficient in killing the E. coli cells. In addition, significant mortality of E. coli was observed when the cell suspensions were exposed to visible light at 458 and 488 nm. Based on the E.  coli survival data at various wavelengths and
dosages, we constructed  a predictive equation to estimate the survival  of E. coli when exposed to
a known  dosage of radiation at a specific wavelength.   Log(S/So) = - (1.089 x 10[superscript]7 e[superscript]-0.0633γ)D
Where S = survivor cell density  (CFU/ml),
So = initial cell density  (CFU/ml),
D = Radiation dose (mJ/cm[superscript]2),
γ = wavelength of radiation (nm).
It was also determined that E. coli cells had an absorption peak between 260-280 nm which coincided with the UV spectrum that had the highest killing capacity for E. coli.  The FTIR spectrums of UV-treated and untreated E. coli showed that there was a decrease of C-O-C and C-O-P bondings after the UV treatment, indicating the destruction of the glycan backbone of peptidoglycan and phosphodiester backbone of
nucleic acids, respectively. There was also an increase in protein content in the UV-treated samples because there was a significant increase in the amide bonds. This increase may be a stress response mechanism of the E. coli cells exposed to the UV treatment. The UV-treated cells also showed an increase in the amount of CH[subscript]2 stretching of fatty acids, indicating a change in membrane structure of the UV treated
cells. Furthermore, UV-treated samples showed an increase of hydroxyl functional group, an indication of an increase of reactive oxidation species (ROS) in the E. coli cells.

abstract:
Ontario’s landmass north of 51° latitude has been designated as the least intensively
managed zone with respect to fire protection. Consequently, large natural fires dominate
the boreal landscape. This northern zone, comprising nearly 43-million hectares of
primarily unmanaged boreal forest, is virtually inaccessible by road. Understanding the
fire dynamics of such an extensive, unmanaged, and inaccessible forest is valuable for
further ecological research.
Three methods of analyzing Advanced Very High Resolution Radiometer (AVHRR)/
Normalized Difference Vegetation Index (NDVI) imagery were compared for post-fire
detection and mapping in northern Ontario. Exposed ground conditions, resulting from
the removal of forest cover, can inflate derived AVHRR/NDVI values. Corrections for
these effects were applied to test whether fire-mapping accuracy could be increased.
The suitability of three threshold-driven change detection methods developed in Alaskan
boreal forests were tested under northern Ontario conditions along with three corrections
for substrate reflectance for 1992, 1993, and 1995 fire seasons. A factorial ANOVA
statistical design was implemented to test equality among various spatial coincidence
variables. Accuracy was assessed using a spatial database.
Existing fire detection and mapping methods using AVHRR/NDVI are not directly
suitable for use in northern Ontario. Results indicate the superiority of a strict, single-threshold
method for reducing false detection and the lenient double-threshold method
for increasing mapped area for each fire. Furthermore, strong correlation was found
between fire size and the area detected to represent them; however, corrections for
substrate reflectance did not significantly increase detection and mapping accuracy.

abstract: "In this study, I will examine the case of 'Tomboy Tools' as a form of gendered material culture. I will analyze the way this company has come to cross the traditional gender boundaries placed on women that has historically alienated them from the domain of tools and home repair. In attempting to bridge the historically opposing worlds of femininity and home repair, the company has used the strategy of making the tools conform to a traditionally feminine gender script (light, cute, pink, etc). Drawing on data from a content analysis, participant observation, and interviews I use a constructivist grounded theory approach (Charmaz 2006; Clarke 2005) to analyze how the identities, practices, and norms of potential female users are projected and reinforced in the design and marketing of the tools. I also consider how potential female buyers respond to these implicit assumptions, and interpret and give meanings to these new cultural artefacts and messages in often competing and contradictory ways."--Abstract

Bullying in schools Ontario Waterloo

abstract:
Bullying behaviour and its adverse health consequences are a major problem in
elementary schools in the Region of Waterloo. The purpose of this project was to gather
baseline information on the frequency and context of bullying behaviour as one way to
evaluate a new framework tool, “Imagine...A School Without Bullying,” as a bullying
prevention strategy. The researcher analyzed baseline data from a parent survey at five
schools in the Region of Waterloo to determine the frequency and context of bullying
behaviour; identify the characteristics of perpetrators and victims (i.e., age, gender, race,
and recent enrollment at the school); synthesize recommendations for improvement of the
program by parents (i.e., qualitative analysis); ^d offer recommendations to the Youth
Health Team of the Region of Waterloo Public Health Department (ROWPHD) to
improve the program. Analysis of the data found that boys are five times more likely than
girls to physically bully at least once a month and more than twice as likely to perpetuate
verbal bullying at the same rate. At a rate of once or twice a month, boys are far more
likely to be bullied physically. Girls are bullied electronically three times more than boys.
Grade 6 students, in comparison to students in Grades 4, 5, and 7, experience a greater
incidence of name-calling. The researcher found a statistically significant difference
between boys and girls with respect to sexual harassment in the form of name-calling.
Parents offered constructive criticism, with the most reported themes being more
supervision, more education, and harsher punishment. Bullying prevention is best
accomplished through a whole community perspective (i.e., students^ teachers, school
staff, parents, community members). Education, awareness, assessment, intervention, and
policy changes are recommended to reduce bullying behaviour.

Identity (Psychology) in adolescence

abstract: This research explores the complicated terrain of secondary school mates' masculinity and the ways they make sense and meaning of these identities in the socio-political context of a feminist, anti-oppressive teacher's classroom. Within this thesis, [the author] argue[s] that schools are complex sites of negotiation for males and their masculine gender performaces. Instead of supporting a "crisis narrative" approach to masculinity and gender in classrooms, this Critical Ethnography looks at the ways in which Seocndary males respond to the social forces in their classroom environment. The findings of this research show that masculine gender performances in school are impacted by situational forces such as location, friend/peer groups as well as family relationships and support. Male students use a "mash-up" of masculine performances, using different tactics to survive the heterosexist and hierarchical classroom environment. Finally, this research also analyzes the way in which a feminist, anti-oppressive (female) educator responds to and interacts with male students and their masculine performances within a shared classroom environment.
