abstract:
Environmental assessment (EA) was originally conceived as a process applying to
discrete projects such as power dams and timber harvest plans, but increasingly it is
being applied to programs and policies for large areas. Such is the case for forest
management, where EA is finding application to regional management strategies. The
aim in this study was to investigate and analyze the quality of two regional EAs of forest
management; (a) the Ontario Class EA for Timber Management on Crown Lands in
Ontario; and (b) the Minnesota Generic Environmental Impact Statement (GEIS) on
Timber Harvesting and Associated Forest Management Activities. The Ontario EA was
a difficult hearing-dominated venture where experts brought testimony before a quasi-judicial
tribunal. The Minnesota EA centred upon quantitative impact analyses
undertaken by inter-disciplinary study teams and documented in concise reports. Both
these EAs looked at forest management issues across huge areas, and both were
completed in 1994.
A broad cross-section of criteria derived from EA literature was used to judge the
quality of the EAs, including factors pertaining to elements of process, technical and
scientific requirements, and outcomes. I applied the criteria in describing and evaluating
the two EAs and found them generally to contrast strongly with each other. The paper
summarizes the strengths and weaknesses of the two EAs so that similar endeavours in
the future can be designed to avoid some of the pitfalls encountered in the preparation
of the Minnesota and Ontario regional environmental assessments.

title: End-to-end shared restoration in multi-domain networks / by Zhiying Gao.

subject: Computer networks - Mathematical models.

subject: Telecommunication traffic.

subject: Multi-domain networks

abstract:
Emerging multi-service data applications require high-bandwidth high-quality connectivity across multiple network domains, each of which is generally controlled by an independent service provider. These applications necessitate the need for highly intelligent survivable routing mechanisms to compute end-to-end paths and to perform functions of protection and bandwidth management across multiple domains. On the other hand, current protection and restoration mechanisms focus on the network survivability inside a single domain network. Powerful dynamic protection and restoration algorithms have been developed for single-domain networks. The majority of these algorithms are based on the exchange of detailed link-state information among the nodes, which makes them less attractive to networks with multiple domains where link-state information needs to be abstracted within each domain for efficiency and scalability reasons. To address this problem, we present two network information abstraction models designed to aggregate link-state information within each domain and only to advertise the aggregated information to other domains. The first abstraction model is referred to as virtual path abstraction model, with which every domain is abstracted as a set of border-nodes interconnected by virtual paths. The multi-domain network is then topologically aggregated to become a single-domain network, called virtual path network, which consists of border-nodes interconnected internally by virtual paths and externally by inter-domain links. The second abstraction model is referred to as virtual node model, with which every domain is modeled as a virtual node with a certain internal minimum capacity that can be advertised to other domains. The multi-domain network is then topologically aggregated to become a single-domain network, called virtual node network, consisting of virtual nodes interconnected by inter-domain links.
We have designed and developed three distributed end-to-end shared
restoration schemes based on the information abstraction models presented
above. These three schemes are referred to as Link Disjointed Virtual Path
(LDVP) restoration. Domain Disjointed Virtual Path (DDVP) restoration, and
Link Disjointed Virtual Node (LDVN) restoration. The LDVP and LDVN
schemes are designed to provide link diversity between the primary and backup paths of each demand, whereas the DDVP scheme is designed to compute a pair of domain-disjointed paths for the demand.
We show that the proposed schemes are more scalable than the existing
restoration schemes because they require less amount of link-state information to be advertised between the domains. This will reduce the routing message overhead and make the proposed schemes to be scalable to large multi-domain networks.
We also evaluate the performance o f the proposed schemes in terms of
capacity usage and restoration time through simulation experiments on two
multi-domain networks; one is based on the NSF (National Science Foundation) network, and the other is based on the European Optical Network. The simulation results show that the proposed schemes save the backup bandwidth significantly because of the sharing of backup resources among failure-disjointed connections. The simulation results also show that the restoration time achieved by the proposed restoration schemes (over the multi-domain network) is around or less than 60 ms, which is within the range accepted in today’s networks.


title: Detection of Deoxyribonucleic Acid Damage Induced by Metal Ion Interactions and Repair of Metal Ion Deoxyribonucleic Acid Cross-links

abstract:
There are many forms of DNA damage. One of these, DNA-metal cross-links are
particularly problematic as they not only affect the tautomeric structure of DNA, but can
also inhibit enzymatic activity and block amplification with DNA polymerases. Since the
inability to amplify DNA can affect many fields of genetic research, it is necessary to
find ways to identify this damage and repair the DNA. Copper is one metal that can form
metal-DNA cross-links and can seriously affect the recovery and analysis of degraded
DNA from forensic or archaeological material. In this research DNA-copper cross-links
were generated for the development of a repair method and applied to an archaeological
sample. The DNA-copper adducts were identified through the use of gas
chromatography-mass spectrometry on several templates of different complexity: single
deoxyribonucleotides, a synthetic 22 base pair double stranded DNA fragment, modern
amplified DNA, and an ancient extract with naturally occurring copper cross-links. A
number of chemicals were considered for direct reversal repair of copper-DNA cross-
links of which ethylenediamine was successful. Treatment of all the templates with
ethylenediamine resulted in the repair of the nucleobase, specifically guanine which is the
most susceptible to copper cross-link formation. The success of the direct reversal repair
was verified using GC-MS based on expected retention time and the identification of ion
fingerprints. The amount of copper-DNA adducts measured in each template varied
greatly as did the success of the direct reversal repair although repair was evident in all
samples.


subject: Stress and Lifestyle Management. Group Therapy Program

subject: Stress (Psychology)

subject: Group counseling

abstract:
Excessive stress can be debilitating when it is not
under careful control. The development of a Stress
and Lifestyle Management Group Therapy Program was
designed to instruct people who have a low stress
tolerance, to deal with and control stress. Stress
management included cognitive therapy, assertiveness
training, and progressive relaxation training.
Emphasized in Lifestyle management was physical
exercise, diet control and weight loss, time
management, the effective use of leisure time,
understanding the purpose of one's social support
system, and other aspects important to a healthy
lifestyle. Clients were referred by doctors, were
male or female, and were between 18 and 65 years of
age. Clients who were accepted into the program
were not severely depressed and did not require
intensive individual counseling. These subjects
were randomly divided into an experimental group and
a waiting list control group. The program consisted
of an individual intake interview, six
one-and-a-quarter hour weekly group sessions, a
group follow-up session three weeks later, and an Individual follow-up Interview. A battery of six
tests assessed the changes In the clients* abilities
to manage stress and related problems and these
measures were taken before and after the program.
The test results indicated a decrease in the level
of depression of the subjects who were treated. The
program was evaluated as a success based on this
result.

Vegetation management

abstract: In recent years, utility vegetation management planners have incorporated a new framework into planning regimes: reliability based vegetation management. This report examines the vegetation management standards of forty North American electricity distributors. Distribution utility vegetation management planners, utility foresters, reliability specialists, and other delegates from the sample provided information related to their respective vegetation management programs. Company profiles and statistics were generated using this information. Study results indicate that, although all vegetation management standards of sample participants exhibit similarities, the ways in which each distributor approaches reliability based vegetation management differ.


title: Predictive and concurrent validity of the Structured Assessment for Violence Risk in Youth (SAVRY)

subject: Violence in adolescence

subject: Violence in adolescence Forecasting

subject: Juvenile delinquency Psychological aspects

abstract:
Youth violence is a serious social problem that is often encountered in the criminal justice
system. Currently, there are very few instruments available that have been specifically
designed to assess violence risk In Juvenile offenders. This study examined the predictive
and concurrent validity of a new Instrument, The Structured Assessment for Violence Risk
in Youth (SAVRY), in a sample of adolescent offenders. The SAVRY was retrospectively
coded using file information on 127 juvenile offenders aged 12 to 18 years. A follow-up
period with a mean of 35.5 months (SO = 14.8, range = 6.0 to 61.0) was used to determine
general and violent reoffending. Results substantiated the predictive validity of the SAVRY
total score for both general and violent reoffending with Areas Under the Curve of .75 and
.77, respectively. Similarly, analysis of the predictive validity of the SAVRY risk ratings
indicated that youths in the higher risk categories were at significantly greater risk for both
general and violent reoffending. As well, the SAVRY was found to be superior to the Youth
Level of Service/Case Management Inventory in the prediction of both general and violent
reoffending. Limitations of the current research are discussed.

Bruce Power Generating Station
Airborne thermal sensors
Effluent research

abstract: Bruce Power Generating Station is located on the shores of Lake Huron and is responsible for generating 30% of the Province of Ontario’s electrical need on a daily basis. Lake Huron is the 5th largest freshwater lake by volume and provides cool lake water to cool the steam generated by the CANDU® reactors. The resulting thermal effluent is regulated and must be monitored to ensure the generating station does not exceed the values published in the operating certificate. Current monitoring is conducted through a series of surface temperature probes at strategic locations. Airborne thermal cameras provide a new dimension to thermal data acquisition and have been tested in smaller capacities on similar industrial complexes. This study compares data collected by surface probes, FireMapper 2.0 (a longwave frame-based thermal camera), longwave thermal data collected by Landsat 8 TIRS, and surface models generated using the CORMIX software suite. The results from this study suggest a strong correlation between the data collected by FireMapper 2.0 and Landsat 8 TIRS. The trend of the ground samples is similar to the data collected by FireMapper 2.0, but a large offset exists between the data sets. Furthermore, the CORMIX model is able to estimate the surface area occupied by thermal effluence, but the spatial bounds of the model require refinement. This study concludes that airborne thermal sensors are sensitive enough to collect useful thermal data for effluence delineation. Some further investigation is required on integrating navigation solutions to generate better accuracy within the FireMapper 2.0 frame-based solution. As well, the study area seemed to reach the extents of the capture abilities of FireMapper 2.0. Airborne thermal technology is worth considering for future effluent research.


title: Sedimentology and geochemistry of the 2.93 Ga Basinal Facies of the Red Lake carbonate platform

subject:
Chemical sedimentary rocks
Lithofacies
Geochemistry
Red Lake carbonate platform

abstract: The Mesoarchean Red Lake carbonate platform is the oldest (~2.93 Ga) known carbonate platform on Earth. It is comprised of a variety of chemical sedimentary rocks including: limestone, dolostone, chert, oxide iron formation, and sulfide iron formation. This study deals with its five different types of deeper water lithofacies, including four chemical sedimentary rocks and siliciclastic black slate, to delineate Mesoarchean ocean chemistry and comprehend the localized depositional settings. Geochemical analysis of selected elements in the chemical sediments were used to constrain depositional processes. Of these positive Eu anomalies in REE patterns suggests that the ocean was heavily influenced by hydrothermal activity and positive Ce anomalies in oxide iron formation indicate that a redoxcline existed in the depositional environment. Zirconium and hafnium in oxide facies iron formation were mostly derived from seawater, and their sorption was dependent on the rate of precipitation of iron hydroxide. Multiple sulfur isotope analyses revealed that mass-independent fractionation of sulfur was operating along with bacterial sulfate reduction, and the source of sulfur was diverse. Organic carbon isotopes increase from ~ -27 ‰ to ~ -20 ‰ up-section towards the shallow portion of the carbonate shelf, possibly reflecting the presence of anoxic phototrophs in the shallows. Inorganic carbon isotopic ratios averaging ~ -1.5 ‰ fall within the range of Archean carbonate and reflect seawater values. Also, δ18O data reveals that dolomitization occurred in a freshwater influenced environment. Evidence such as increasing Mn concentration towards the carbonate platform and positive Ce anomaly in oxide iron formation, as well as redox-sensitive element enrichment in the chemical sedimentary rocks, suggests that bacterial O2 production was somewhat active in the Mesoarchean sea. The interlayering of various types of chemical sediments at differing stratigraphic scales indicates that localized ocean chemistry changed repeatedly over both short and long time intervals. Carbonates were perhaps formed in the slightly oxic shallow water environment, while magnetite and chert were precipitated in a suboxic environment distal to any venting fluids and iron sulfides accumulated in a reducing, anoxic environment during intervals of intense venting of hydrothermal fluids. Shale was deposited as background sediment and accumulated during cessation of chemical sedimentation. Finally, the deeper water sediments repeatedly interlayered with the shallow water stromatolitic carbonate successions, which suggests multiple events of carbonate platform flooding.


title: Sound and silence in selected poetry of Duncan Campbell Scott

abstract:
The poetry of Duncan Campbell Scott has always been
recognized by the Canadian literary establishment as being
worthy of attention. His work usually appears in most of
the textbooks and anthologies of Canadian Poetry, and there
is little or no question that his poetry stands as a vital
chapter in the history of Canadian literature. However, despite
the fact that there have been many studies done on Scott's
poetry, there remain aspects of his work that have not been
given enough attention. This thesis examines, in particular,
the role that sound plays in what is generally considered
to be the best of his work. Chapter one discusses how Scott
allows the reader to hear the conflict in Nature, the conflict
found between Man and Nature, and the conflicts found within
Man himself. These conflicts represent the major themes of
his poetry. Chapter two deals with how Scott uses sound to
appreciate and perhaps even understand these conflicts by
achieving, and sharing with the reader, a heightened spiritual
state. Finally, chapter three attempts to show thematic
consistency in much of Scott's poetry resulting from the sharing
of his poetic consciousness as described and determined by
sound.


title: Study of the depositional environments of the Halfway Formation, British Columbia, Canada

subject: Halfway formation

subject: Geology, Stratigraphic Triassic

subject: Geology British Columbia Fort St. John Region

abstract:
The upper sands of the discontinuous Halfway Formation
to the northeast of Fort St. John were formed as barrier
islands deposited perpendicular,or nearly perpendicular to
the dip of the paleoslope of the Western Canadian
Sedimentary Basin. These upper sands of the area of study
were deposited during a transgressive phase of the Triassic
sea to the northeast,and formed the basal unit of an
onlapping sequence comprising the Halfway and the Charlie
Lake Formations that disconformably overstepped the
erosional surface on the silty dolomite of the Doig
Formation. The Weasel sand body was deposited during a
pause in the transgression,and then was submerged by a rapid rise in sea level. The Wildmint to Beatton barrier islands
trend was deposited during a second pause in the
transgression.These barrier islands would appear to have
been deposited under arid conditions resulting in restricted
lagoonal environments. The lower sands of the discontinuous
Halfway Formation which only occur at a few locations in
southern Willow and Wildmint ,would appear to have resulted
from tidal inlet action that eroded channels into the Doig
Formation below the base of the upper sands forming the
barrier island complex. These later were filled with sand.  Then this barrier island trend was submerged by renewed
transgression of the Triassic sea.The source of the
sediments comprising the discontinuous Halfway Formation
probably was to the north and northeast of the area of
study.

subject:

Cognitive change (lifestyle factors)
Alcohol use & cognition

abstract:
Age, sex, and alcohol use have been identified as factors that influence cognition. The present
study aimed to replicate and extend these findings by examining the effects of age, sex, alcohol
use, and their interactions on cognition in a large sample of older Canadian adults (N=30,097, aged
45-85). Cross-sectional data from the Canadian Longitudinal Study of Aging (collected during the
first wave of data collection between 2011 and 2015) included a cognitive test battery, allowing
for domain-specific analyses. The results supported the following hypotheses: (1) younger adults
have higher cognitive test scores than older adults, (2) women score higher than men on tasks
assessing memory and verbal fluency, and (3) alcohol use is associated with higher cognitive test
scores with a very small effect size. Small interactions occurred between age, sex, and levels of
alcohol use. Study limitations and small effect sizes, combined with previous evidence of
neurotoxic and other adverse effects of alcohol, suggest that the finding of a cognitive benefit of
alcohol use should be interpreted with caution. The large sample, breadth of measures and
covariates, age and sex analyses, and consistency of the findings across analyses suggest that
further longitudinal and experimental research is warranted.

The reaction between NiC12.6H20, NaBH4 or NaBH3CN and either PPh3 or a series of phosphines of the type Ph2P-(CH2)n-PPh2 (n=1-5) and also cis-dppe under CO atmospheres have been studied under a range of experimental conditions. The important factors which affect the reaction pathways are; the ratio of metal: phosphine: NaBH4 or NaBH3CN, the rate of addition of reducing agent, the temperature and the duration of reaction.
Complexes with bridging and
monocoordinated dppm were obtained, while with dppe,
complexes with bridging, chelating and monocoordinated
phosphine were obtained. Hetero and homobimetallic complexes have
been prepared from mono-coordinated bis-phosphine complexes and were characterized by a variety of spectroscopic methods, by x-ray powder diffraction and in one instance by a single crystal x-ray diffraction study. (see document for full abstract)

abstract: Environmental issues and conventional fossil resource depletion has directed the attention of researchers to seek clean or alternative fuels. Biodiesel was introduced as an answer to day-to-day increases in diesel consumption from heavy machinery to locomotives. The availability from a wide variety of feedstocks (more than 350 crops) and the reduction in emissions such as carbon monoxide (CO), unburnt hydrocarbons (HC) and smoke opacity has made biodiesel attractive among other fuel alternatives. Some of its disadvantages include inferior cold flow properties and slightly higher NOX emissions. Expanded polystyrene (EPS) counts for 22% of total plastic waste globally. Proper recycling of EPS at remote locations is practically not feasible. Canola biodiesel is an effective solvent for EPS. This work aims in dissolving EPS at varied concentrations in canola oil biodiesel, and fueled on two modern diesel engines (a light-duty and a heavy-duty) and their performance, emissions are analyzed at different loads and engine speeds. The improvements that resulted after adding the additives (i.e., acetone, tetrahydrofuran, di ethyl ether, xylene and toluene) to EPS-infused biodiesel are also noted on the same engines at various speed and load conditions. The Cummins heavy-duty engine was powered by fuels at two idling conditions (700 rpm and 1700 rpm). The HATZ light-duty engine was powered by fuels at low, medium and high speeds at 1000 rpm, 2100 rpm and 3000 rpm. The fuel properties such as calorific value, density, and viscosity of each fuel are also investigated. The microscopic structure and the particle size distribution of each fuel sample were evaluated to monitor the changes when adding EPS, and any improvements when adding additives were noted.


title: Qualitative study of five FSL teachers using constructivism to support second language learning

subject: Constructivism (Education)

subject: French language (Study and teaching as a second language)

subject: Second language learning & language pedagogy

abstract:
This qualitative study concerns how five participants who teach French use
constructivism as a theory of learning in their classrooms and how this effects their
students’ learning. In a constructivist classroom, learning experiences are based on the
construction of knowledge, prior knowledge, and social context. Students make sense
of what they are learning in relation to what they already know and new knowledge is
gained by sharing of ideas with others. A snowball sampling technique was used to
generate a list of five participants. The interview process involved a semi-structured
question format, allowing for probes to explore the responses further. The participants’
own words and experiences are used to illustrate how their students acquire a second
language. The findings reveal how active learning helps students make sense of what
they are learning, assume ownership of their education and have fun in the classroom.


title: Caring : perceptions of students and a community college diploma nursing program

subject: Nursing students Ontario Attitudes

subject: Nursing schools Ontario Evaluation

subject: Nursing schools Ontario Faculty Attitudes

abstract:
While caring has been a recent focus of nursing and curricula for
nursing education, little research exists on student and faculty
perspectives of caring. There is a particular lack of research on
caring within diploma nursing programs which prepare the majority
of Registered Nurses in Ontario. This researcher sought to
investigate to what extent a diploma nursing program in an Ontario
community college, enables caring among its' students and faculty.
What behaviours/practices inhibit and foster caring from student
and faculty perspectives? A phenomenological approach was used to
gain the student and faculty views of caring and uncaring
experiences within the nursing program. Three senior nursing
students and three full-time nursing faculty described their
experiences of caring and uncaring, and the effects of these
experiences on them. The descriptions were analyzed using a
modification of Giorgi's method of analysis. Based on the findings,
behaviours which inhibit and foster caring were identified. The
meaning of caring for each participant and for the whole was
described and a visual description of the structure of the meaning
of caring is proposed. The visual description illustrates
vulnerability as pivotal to the caring experience and the effect of
behaviours which inhibit and foster caring on the extent to which
caring is enabled. The emergence of the role and importance of the
one cared-for and their freedom to be cared-for is discussed. Two
categories of caring emerged from this study, day to day caring and
caring in a crisis. The two categories of caring are compared to Noddings* (1984) discussion of 'rule-bound* caring and caring
without rules. A question is raised regarding a relationship
between faculty caring and the nursing students' apparent conflict
with their image of a nurse and their image of themselves.
Implications of the research include development of strategies to
foster caring in practice and in education and the development of
nursing curricula to incorporate theories of caring and qualitative
approaches to learning. There are implications for faculty in terms
of collegial relationships and as role models for students and each
other. Further research on the notion of vulnerability in caring
and what influences one to care or not care is suggested. Research
focusing on the one cared-for and on the possibility of faculty-student
research teams is recommended.


title: Cadences of voice, conversations of change : the poetry of Bronwen Wallace

abstract:
The primary objective of the thesis is to examine three fundamental elements of
Bronwen Wallace's narrative poetry: stories, conversations and voice. Wallace
employs these methods to probe the moral, personal and political conditions of
women and in doing this, offers readers the untold stories of women's lives. This
grounds her poetry within the particulars of everyday life, offering readers insight
into the mundane yet magical lives of women.
I explore these three fundamental elements to illustrate how Wallace records
the daily particulars of women's lives with the intent to liberate women further.
She offers readers a different perception of women's lives, different in that it
detracts from the patriarchally defined perceptions of women. This mitigation of
patriarchy begins in chapter one with the examination of inverted perception in
Wallace's second collection of poetry. Signs of the Former Tenant. Fundamentally,
Wallace sees limitation and possibility as one and the same. She invites the reader
to be p art of the conversations of women who have taken the limitations of their
lives (often imposed by patriarchy) and created possibilities.
Argument, a progeny of conversation, is file heart of Common Magic, the third
collection of poetry. The form of argument becomes a vehicle for conveying
different perspectives of violence within women's lives. I examine this violence in
chapter two and show how the conventional perception of battered women as
'victims' is inverted to women as survivors. This inversion leads into the
reworking of the conventional male-defined elegy. The elegy is redefined to include
the celebration of women's friendships: a celebration of the earthly and ordinary
texture of women's lives and relationships.


title: Perceived exertion and work capacity during the menstrual cycle

subject: Menstruation Exercise

abstract:
The purpose of this study was to identify and confirm
biochemically three phases of the menstrual cycle in 14 well
conditioned athletes and then to examine the effects of the
various phases on work capacity, perceived exertion and
lactic acid accumulation following individualized work
tasks. Radioimmunoassays of plasma estradiol and progesterone
were used to confirm the midluteal and mid-follicular
phases of the cycle. Subjects performed a 12 minute sub- •
maximal work task consisting of 3 minutes at 60%, 3 minutes
at 70% and 6 minutes at 80% of their measured maximum work
capacity. Perceived exertion was recorded every 2 minutes
using the Borg 15 Point Scale. After a 15 minute rest the
subjects were asked to run as long as they could at a work rate corresponding to 100% of their maximum work capacity.
Blood samples were drawn for lactic acid assays prior to the
start of the initial run, 2 minutes after the sub-maximal
run and 5 minutes after the run to exhaustion.
The phase of cycle had no influence on perceived exertion
or on lactic acid accumulation. Maximum run times to
exhaustion increased significantly (p < .05) in the midfollicular
and midluteal phases when compared to day 1. The
average increases were 17.9% and 40.2% respectively. These
findings indicate that work capacity is maximal in the
midluteal phase.

abstract: The designation of Thunder Bay’s Harbour as an Area of Concern (AOC) by the International Joint Commission prompted the need for Remedial Action Plans to improve historically significant habitats (RAP, 1991; RAP 2004). In an attempt to restore, protect, conserve, and prevent further ecosystem degradation, a series of projects were developed with site-specific objectives to benefit the Thunder Bay AOC. The removal of contaminants, habitat compensation engineering, and species introduction was implemented to enhance the productivity of littoral zones and reduce areas of degraded habitat along the industrialized shoreline (RAP, 1991; RAP 2004). A multi-methodological approach is applied in this study to assess the physical and spatial habitat characteristics of six rehabilitation projects executed by the Thunder Bay Remedial Action Plan team (RAP) including McKellar Embayments, Neebing-McIntyre Floodway, Northern Wood Preservers Alternative Remediation Concept, Sanctuary Island, Current River, and North Harbour. A habitat classification framework is applied to utilize specific habitat indicators to rank sites based on their fisheries value and role in littoral zone regeneration and recovery. The majority of the projects were successful in improving habitat complexity, receiving a moderate to high ranking in the habitat classification. Further improvements in buffer zone extent, diversity, and thickness would benefit the aquatic ecosystems and would improve overall habitat scoring. River habitats, such as Neebing- McIntyre, require more extensive work to achieve outlined restoration goals as the embayment features did not have the desired outcome. Continued monitoring and management will ensure the success of these sites and provide evidence to support ongoing habitat restoration efforts in the Remedial Action Plan Program.

my own feminist analysis: the feminine, the feminist, and the female.


title: Effects of soil temperature on growth and biomass allocation in four boreal tree species

subject:
Soil temperature
Effect of temperature on forest biomass

Boreal forest

abstract:
Trembling aspen (Populus tremuloides Michx.), black spruce (Picea mariana (Mill.)
B.S.P.), white spruce (Picea glauca (Moench) Voss), and jack pine (Pinus banksiana Lamb.)
seedlings were subject to seven soil temperature treatments 5,10, 15,20,25,30 and 35°C. At
the beginning and end of the experiment, the height and diameter of all seedlings were
measured. Ten seedlings from each treatment combination were harvested at the end of the
experiment for the determination of biomass allocation. It was found that soil temperature,
species and interaction of soil temperature and species had significant effects on biomass and
relative growth rate (RGR) of diameter. The relationship between each parameter and soil
temperature was modeled using a 3rd order polynomial function. The model showed that the
optimum soil temperatures were 19.4°C, 17.3°C, 15.3°C and 21.8°C, respectively, for aspen,
black spruce, white spruce and jack pine. The biomass variables showed nonlinear responses
to changes in soil temperatures between 5°C and 30°C in all tree species. All the aspen
seedlings, about 40 percent of jack pine, 20percent of white spruce and black spruce seedlings
survived the 35°C treatment during the experiment. Among the species, aspen had the largest
response in total biomass and biomass of different components to soil temperatures. The
maximum total biomass for aspen was about 7 times the minimum value, the corresponding
values for black spruce, jack pine and white spruce were 2.2, 2.4 and 2.3 times, respectively.
The total biomass and biomass of different organs at soil temperature 5°C were smaller than
those at temperature 30°C for aspen, black spruce and jack pine. The results were reversed for
white spruce. The total biomass at 5°C was 14.3 percent of the value at the optimum soil
temperature for aspen, the corresponding values for black spruce, jack pine and white spruce
were 45 percent, 42 percent and 42 percent, respectively. Soil temperature did not
significantly affect leaf to root ratio, shoot to root ratio, shoot mass to total mass ratio (SMR),
leaf mass to total mass ratio (LMR), or stem mass to total mass ratio (SMR). But there were
significant differences between species in all the above ratios and different species responded
differently to soil temperature treatments. The relative growth rate (RGR) also varied with
species. Soil temperature did not affect RGR in jack pine and white spruce. The RGR of
black spruce was sensitive to soil temperatures over the whole range while RGR of aspen was
only sensitive to soil temperature below 15°C.


title: The child, the family, and society in Ontario, 1850-1900, according to four educational journals

subject: Family Ontario History Education

abstract: To understand the position of the child in Ontario between 1850 and 1900 is to know a great deal about the society in which he functioned. The status and role of the child was the most vital issue of the time. Social reformers assigned to him a key role in the future advancement of their society. If one generation of children could be inculcated with all the proper values, then present social evils would disappear.


title: Method for demonstrating aesthetic preferences within artistic pictures

subject: Aesthetics Painting

abstract:
Berlyne (I97I, pp. 28-29) acknowledged that "Reactions to artificially simple sights and sounds are admittedly a long way
from appreciation of art." However, a concern regarding the
use of art is an absence of control over the determinants of
the subjects* preferences. This research attempted to overcome
these methodological problems through the use of artistic pictures
with the variation of a single stimulus within each picture,

abstract: This study examined the test-retest reliability and concurrent validity of the Repeat Ice Skating Test (RIST). This was an on-ice field anaerobic test that measured average peak power. It was validated with 3 anaerobic lab tests: Vertical Jump, Margaria-Kalamen Stair test, and the Wingate cycle ergometer test. The study's subjects were 14 males aged 11-12 on a Peewee "A" level ice hockey team in the Thunder Bay area.

PELLETIER, M. R. (1988). Effect of prenatal cadmium
exposure on development and behavior of selectively
bred genetic lines of rat: The purpose of the study was
to investigate the effects of cadmium exposure as
related to dose and genetic background of the organism.
Twenty-seven dams from three genetic lines of rat (Roman
High Avoidance - RHA/Lu, Roman Low Avoidance - RLA/Lu,
Satinder's Heterogeneous Stock - SHS) were injected
subcutaneously (s.c.) with either 0.075 mg/ml/kg, 0.225
mg/ml/kg cadmium chloride (CdCl2) or physiological
saline (0.85% NaCl) for 21 days during gestation.
Progeny were observed daily until weaning (28 days) for
developmental and reflexive indices. No teratogenic
effects were observed. Progeny did not demonstrate any
dose related differences in reflexive/developmental
indices. Progeny were tested in the open-field at 35
days of age and for Either-way avoidance response at 41
days of age. The avoidance paradigm was found to be a
more sensitive indicator of cadmium-induced behavioral
effects. The SHS genetic line appeared to be more
susceptible to cadmium-induced behavioral effects. A
cadmium-induced hyper-responsiveness hypothesis was Inductively Coupled Plasma (ICP) Spectroscopy. Cadmium
levels were observed to increase in a dose-dependent
manner in maternal tissues. It was suggested that
future research be directed towards elucidating the
neuro-behavioral mechanisms of cadmium-induced
hyper-responsiveness.

subject:

Soil compaction, PH & carbon

abstract: This thesis examines aspects of soil quality between a hayfield and pasture site on a farm in Northwestern Ontario. Soil compaction, pH, and carbon were the main aspects looked at between the two sites. The purpose of this study is to answer how soil compaction, pH, and carbon content differ between a hayfield and pasture site, and to provide a baseline of soil quality data that can be used in determining the effect of farming practices on soil quality in the future. A one-way ANOVA was completed to determine that though the hayfield had a significantly higher percentage of carbon and sulfur, there were no significant differences (α = 0.05) found amongst any of the other factors including carbon and sulfur amounts (kg/ha). A regression was also run to determine the strength of a linear relationship amongst CNS. These relationships were very strong with r2 values of 0.938 (carbon v. nitrogen), 0.850 (carbon vs. sulfur), and 0.824 (nitrogen v. sulfur). It can be concluded from these results that though very little difference exists between the two fields, the strength of the linear relationships examined were very strong. These results are further discussed and analyzed concerning why there was a lack of significant differences amongst the fields, and it was suggested that the brevity of the research timeframe did not allow for the full representation of the effect of the current farming practices taking place on the site. Of key importance is that this data is identified as a baseline dataset that will provide an excellent foundation for future studies looking to identify how farming practices affect soil quality.

abstract: There is a growing realization that healthcare is a knowledge-intensive field. The ability to capture and leverage semantics via inference or query processing is crucial for supporting the various required processes in both primary (e.g. disease diagnosis) and long term care (e.g. predictive and preventive diagnosis). Given the wide canvas and the relatively frequent knowledge changes that occur in this area, we need to take advantage of the new trends in Semantic Web technologies. In particular, the power of ontologies allows us to share medical research and provide suitable support to physician's practices. There is also a need to integrate these technologies within the currently used healthcare practices. In particular the use of semantic web technologies is highly demanded within the clinicians' differential diagnosis process and the clinical pathways disease management procedures as well as to aid the predictive/preventative measures used by healthcare professionals.

subject: Mountain pine beetle (Dendroctonus ponderosae)

subject: Climate change and mountain pine beetle biology

subject: Impact of mountain pine beetle outbreaks

abstract:
The mountain pine beetle, Dendroctonus ponderosae, (MPB) is the largest forest
disturbance factor throughout its range in North America. The most recent MPB
outbreak began in the 1990s and has resulted in an approximate loss of 723 million
cubic meters of timber. The current global warming trends have seen global
temperatures increase by approximately 1°C and are forecasted to rise by an additional
0.5-1.5°C over the preceding decades. These temperature increases are having a large
impact on the MPB range, biology, and physiology. The range of MPB has expanded
significantly in recent decades and is forecasted to continue to increase significantly in
all directions as well as an increase in elevation. With further climate warming, there is
a possibility of the MPB invading the boreal forest and using jack pine as host trees.
MPB oviposition time, development, and winter survivability rates have been altered
due to rising temperatures.

subject: Civics, Canadian Study and teaching (Secondary) Ontario

subject: Teacher job satisfaction

subject: Self-efficacy

abstract:
The purposes of this study were a) to identify if the introduction of the tenth grade civics
course had effected the teacher efficacy beliefs held by those teachers, within three school boards
in Ontario, who were to implement the course and b) to determine the implications of the
effected efficacy beliefs on the implementation and continuation of the secondary school civics
course. The subjects were chosen from three randomly selected school boards 6om Ontario.
There were two methods used to gather the data for this study. These two methods were
open-ended questionnaires, as well as semi-structured interview sessions. The findings from both
research methods were compared and contrasted with one another. The similarities and the
differences between the two research methods were identified and recorded. Each of these two
methods were used to elicit the lived experiences of the participants, in the attempt of developing
a well-rounded and in-depth conclusion to the research questions. The responses given by the
participants in both the interview sessions and the open-ended questionnaires were summarized.
The key points raised by the respondents were identified as (a) Influence on changes to
curriculum, (b) Ownership, (c) Those teachers who are being asked to teach the course, (d)
Training provided to teachers, (e) Support structures availability, (f) Resources usefulness, (g)
Course Expectations, (h) Course Practicality, (i) Time Constraints.
In conclusion, it was determined that there was an effect on the teachers' sense of
efficacy beliefs. It was further concluded that while the participants were pleased to see a course
address civic awareness, the majority of respondents made it clear that there needs to be a wide
variety of changes made to the course to improve its implementation and ultimately it chances
far long-term continuation within the school setting.

abstract:
This case study examined the impact of using designed visual representations of simple
linear functions on Grade 2/3 students’ development of algebraic thinking. I also looked
for the connections between the use of visual representations of linear functions and
young students’ understanding of multiplication. A pre-assessment interview, five-lesson
intervention, and post-assessment interview sequence was used over the span of one and
a half weeks with a retention task that followed approximately two weeks later. The fivelesson
intervention was developed to prominently feature designed visual representations,
along with other representations (e.g. table of values, pattern rules, narrative contexts), of
simple linear functions to encourage students’ development of explicit reasoning skills.
All students developed some level of explicit reasoning and were able to generalize about
simple linear functions by the end of the study. Most students moved beyond recursive
thinking and were able to generate and apply explicit pattern rules for simple linear
functions in order to generalize about any term within that function. Students’
development of explicit reasoning in order to work with simple linear functions often
sparked a need for a new operation: the invention of repeated addition and, or,
multiplication. Activities involving explorations of simple linear functions that
prominently feature designed visual representations led most of the students in the study
to develop explicit reasoning skills and an early understanding of multiplication.

subject: Loot boxes (gambling and gaming behaviours)

abstract:
The current study examined whether engaging with loot boxes (i.e., in-game “boxes” that can be
won within a game or purchased with in-game currency or real money, and which contain a
random selection of prizes or objects) was associated with increased endorsement of gamblingrelated cognitions around luck and chance (i.e., controlling the outcome of a chance game) that
have been observed in gamblers. Socializing was also proposed to act a mediator between
irrational cognitions and loot box use. Further, self-generated motives to engage with or refrain
from gambling, gaming, and loot box content were also examined. University students (n = 321)
and community participants (n = 279) completed a battery of online questionnaires that included
measures of problem gambling (i.e., Problem Gambling Severity Index), gambling-related
cognitions (i.e., GamCog, Belief in Good Luck Scale), problem gaming (i.e., Internet Gaming
Disorder Scale), and risky loot box engagement (i.e., Risky Loot Box Index). Quantitative
analyses, including a one-way ANOVA on gambling-related cognitions (e.g., luck), indicated
that gamblers had higher scores than loot box users on a measure of gambling-related cognitions,
but that these results were likely statistically but not clinically significant. No evidence for
socializing as a mediator was found. Qualitative content analysis identified several overlapping
motives to engage or refrain from engaging with gambling, gaming, and loot box content. For
example, the chance to win was identified as a motive to engage with both gambling and loot
box content. Additional exploratory analyses revealed that loot box use is linked to problem
gambling and gaming. Overall, these findings provide further context and insight into the
burgeoning research on loot boxes, their relation to gambling and gaming behaviours in terms of
gambling-related cognitions (e.g., luck) and problematic behaviour (e.g., problem gambling,
problem gaming), as well as motives to engage with or refrain from such content.

abstract: Barclay's Bog is located approx. 40 km. north of Thunder Bay, Northwestern Ontario and borders the Hawkeye Lake Watershed Study Site.

abstract:
Aspects of the microclimate, peat depth, surface
topography, stratigraphy, hydrology, water chemistry, and
vegetation were measured at Barclay’s Bog, a small kettle
bog in northwestern Ontario.
Shading from the forest surrounding the bog results in
cool, humid conditions at edge areas. Significantly lower
temperatures, both above and below the peat surface, and
higher relative humidity were recorded by instruments near
the edge than at the centre. The only exceptions were mean
maximum temperature at the peat surface (which was higher at
the edge) and mean temperature at 1 cm below the surface (no
significant difference between centre and edge), probably as
a result of restricted air movement caused by the trees near
the edge. Snow persists longer in the spring at the edges
of the bog (especially the south edge) as a result of
greater accumulation due to drifting and slower melting
associated with lower insolation.
The highest surface elevations are found in a narrow
band along the north, west and south edges of the bog, as
well as at several tall hummocks. The lowest elevations are
found at northeastern edge of the bog and extend to the
floating mat at the centre. Difference between the highest
and lowest point is approximately 65 cm.
The position of the bog on the Dog Lake Moraine
indicates that it is situated in a glacial kettle hole and


title: Working-out : women's work at a leisure facility

subject: Sex role in the work environment Ontario Thunder Bay

subject: Aquatic sports facilities Ontario Thunder Bay Employees

abstract:
This thesis investigates women's formal and informal
marginalization at work, focusing on employment and job
assignments in the aquatics department of a leisure facility
in Thunder Bay. I outline the theoretical perspectives on
part-time work, methods of segregating women in employment,
the social construction of space use, and sport ideology.
The economic, political, and cultural fabric of the city is
detailed, as well as its ties to the employment trends of
the Corporation of the City of Thunder Bay and the specific
site under study. The work performed in the aquatics
department of the facility is described, focusing on the two
basic divisions of labour, lifeguarding and instructing, and
the mechanisms of control used by management.
The impact on employees' work experiences of
traditional concepts of women's natural abilities coupled
with the physical and social environment of their work have
not been studied extensively. This thesis illustrates how
gender ideologies present in contemporary Western culture,
especially their specific manifestation in the regional
culture as reflected in the discourse and practices of users
and workers at the facility, generates gender segregation at
the worksite. At the specific work-site investigated, these
factors have a substantial influence on the distribution of
jobs and tasks among male and female staff. Despite possessing the same qualifications and being hired under the
same job titles as men, gender ideologies and the practices
that are inextricably bound up with them function to isolate
women in stereotypical jobs.


title: Needle flavonoids and population differentiation in the Abies section Nobilis Engelm

subject:
Balsam fir
Chemotaxonomy
Flavonoids

abstract:
The Abies section Nobilis Engelm. consists of two high-elevation
tree species that grow in the mountains of Washington, Oregon and
California. The two varieties of A.magnifica A.Murray grow south of
A.procera Rehd. One of these varieties, A.magnifica var.shastensis
Lemm., is intermediate in some characteristics and locations between the
two "typical" species. The goal of this thesis was to clarify species and
population differentiation in the section Nobiiis. To this end, nine
populations of mature and twelve populations of immature trees were
collected along a north-south transect that cut through most of the range
of the section. The flavonoids were extracted from dried needle samples
selected from each of the sample trees, and a flavonoid profile was
determined for each tree. These individual tree profiles were used to
prepare a composite flavonoid profile for the whole section.
Sixty-four probable flavonoid compounds occurred in the sample
trees, of which forty-seven were at least partially identified. Twenty-four
variable compounds were chosen for analysis. Variation was assessed
using product-moment correlation co-efficients, frequency histograms,
principal components analysis, weighted-pair-group cluster analysis,
discriminant analysis and cladistic analysis. These different statistical
techniques allowed comparison between the different interpretations of
population variation.
Four factors appear to underly the pattern of population variation in
the Abies section Nobilis : (1) evolution of the section under the diverse
and changing conditions that have prevailed in the Pacific Northwest and
California since the Oligocene epoch; (2) hybridization between
morphologically, ecologically and/or chemically differentiated populations
of trees within the section; (3) the presence of a genetically variable gene
pool in the section as a consequence of these two factors; and (4) the expression of a portion of that variability as adaptation to
different stages of forest succession.
A.procera is an early-successional species with a gene pool that
is more uniform than A.magnifica, which is essentially a late-succession
or climax species. Flavonoid differentiation between these two species is
not as distinct as has been observed in the Abies section Balsamea
Engelm. Aprocera tends to exhibit acetylated monoglycosides
consistently whereas A.magnifica does not, and A.magnifica tends to
accumulate glycosides of dihydrokaempferol and taxifolin where
A.procera does not. These differences apparently have been obscured
somewhat by variation between the flavonoid complement of mature and
immature trees, by migration and fragmentation of the range of the
section Nobilis since the Oligocene epoch, and by hybridization within
the section.
The needle flavonoid results reported by this thesis, supported by
published ecological, morphological and terpene data, confirm the current
recognition of three taxa in the section. However, the variety shastensis
exhibits enough differentiation to warrant further investigation into
separation of that taxon into three or four separate taxa: (^) A. procera x
A.magnifica; (2) relictual populations of A.magnifica var.shastensis
in Tulare County, California and the Klamath Mountains of California and
Oregon; and (3) A.magnifica var.shastensis from the North Coast
Ranges of California.

abstract:
Triaxial compression tests were preformed such that
changes in the magnetic susceptibility anisotropy with strain
would be represented by experimental approximations of simple
shear and pure shear. Both types of tests were performed on
artificial materials of high magnetic susceptibility at room
temperature and atmospheric pore fluid pressure. Experimental
displacement-rates and strain-rates were computer controlled
during testing.
Two different shear zone materials were employed for the
"simple shear" testing, a sand-cement mixture and a
calcite-cement mixture. Three series of simple shear tests
were conducted on the sand-cement material at various
confining pressures; Series A, at 0.689 kbars, Series B at 1.0
kbar and Series C at 1.5 kbars. Two series of simple shear tests
were conducted on the calcite-cement material, Series 1, at
1.0 kbar confining pressure and Series 2 at 1.5 kbars Pc. For
both materials a constant axial displacement-rate of 5.0x10-6
inches, s-1 (corresponding to a slip displacement-rate on the
shear zone walls of 8.7x10-6 inches, s-1) was employed.

abstract: Over time, patients from acute care showed greater declines in symptoms, frailty, and resource utilization than other groups. Individuals discharged to LTCH were rated highest in queried symptoms (activities of daily living, cognitive impairment, aggression) and frailty, while those discharged to private homes were higher in resource intensity. Individuals discharged to acute care also experienced steeper declines in resource utilization on average than those discharged to acute care facilities. Future focused research into predictors of between hospital variability in outcomes and the surprising resource-intensity findings for those discharged to health care are suggested.


title: Program proposal : guided self-help bulimia nervosa program delivered in primary care [research project]

subject: Bulimia Treatment

abstract:
Bulimia nervosa is a complex emotional and physical illness that presents
challenges for primary care providers in identifying and supporting individuals with this
eating disorder. Many patients experience difficulties in accessing specialist
psychological treatments. In particular, mature patients and those in rural settings may
find significant barriers to cognitive behavioural therapy delivered in specialist settings.
Guided self-help administered in primary care can be an effective first step in the
treatment of less severe bulimic patients. This project provides a literature review on
the efficacy of self-help treatments for bulimia nervosa, outlines a conceptual
framework for more intervention at the primary care level, and proposes a program to
develop and Implement a guided self-help tool for the treatment of bulimia nervosa in
primary care.


title: Dynamic model and control of vehicles

subject: Automobiles Handling characteristics Mathematical models.

subject: Automobiles Springs and suspension Mathematical models.

subject: Automobiles Riding qualities Mathematical models.

abstract:
In this thesis the author develops a 14 degrees-of-freedom (DOF) full-car model. The
model draws from and improves upon features and setups of certain existing vehicle
dynamics models. The proposed model provides a means to simulate vehicle ride and
handling behaviors. An accurate prediction of such behaviors will lead to the proper
control and design of vehicles.
The vehicle’s kinematics and dynamics are developed to reflect the interactions
between the rigid mass elements of the model such as the vehicle body and the wheels.
The mathematical model includes the nonlinear characteristics of the tires, the three
dimensional motions of the sprung and unsprung masses, the inertial coupling between
the sprung and unsprung masses, and the restraints and forces imposed by the suspension
components. The frictional forces developed at the road-tire contacts are modeled by the
single point contact version of the Lund-Grenoble (LuGre) dynamic friction model. An
extension of the LuGre friction model is presented to take into account the coupling
between the rotational and translational motions of the wheels.
Three different numerical study cases are selected to verify the model’s capability in
representing various vehicle dynamic situations with respect to the model’s accuracy and
to the model’s range of applicability.
The issue of active suspension is subsequently discussed. A non-switching sliding
mode controller is incorporated into the proposed vehicle model and a substantial
reduction in the spectral intensity of a vibration mode of the vehicle body is achieved.
Simulation results suggest that the rigorous modeling and mathematical
development yields a model that captures satisfactory ride comfort and vehicle
performance.

abstract:
The effect of participation in a physical fitness programme of
moderate intensity on plasma lipoprotein cholesterols, total cholesterol,
triglycerides and apolipoprotein-A levels was investigated.
Forty-nine inactive individuals participated in a sixteen week
exercise programme that consisted of three sessions weekly with one
and one-half hours in each session. The results were compared with
those of a non-participating group.
Results suggest that a programme of physical exercise of moderate
intensity of a relatively short duration (sixteen weeks) can have a
beneficial effect by modifying the plasma lipid constituents in
potentially high risk individuals, particularly those over 40 years
who have low HDL-cholesterol blood levels.

abstract: With increased concerns over greenhouse gas emission and decreasing fossil fuel supplies, biomass is increasingly seen as an alternative option for energy and chemical production. There are several technologies available to upgrade biomass to useful energy and fuel products, and one of the most promising is gasification. Tar formation is the major challenge for biomass gasification. Formation of tars represents not only a decrease in gasification efficiency, but would cause some operation issues such as fouling and potential clogging due to the condensation of tars as they cool downstream.


title: Development of restrictive disclosure in children's communication with peers

subject:
Self-disclosure
Interpersonal communication in children

abstract:
Research supports the conclusion that adults show a
pattern of restrictive disclosure in which they choose to
disclose intimate information to friends rather than
nonfriends. From a developmental perspective, however, only
limited evidence exists for this restrictive disclosure to
friends process in children. The present study was designed
to investigate whether, and if so at what age, children show
the restrictive disclosure to friends in their actual
communication with peers. Sixteen subjects (8 boys and 8
girls) selected from each of kindergarten, second and fourth
grades were asked to "send a message" on a tape recorder to
both a peer friend and peer nonfriend and talk about five
categories which varied in personal content. The results
indicated that the restrictive disclosure to friends pattern
was evident in all three grades examined. Subjects disclosed
overall, more high intimate but not more low intimate
information to friends than to nonfriends. Age differences
were also found in which there was an increase with age in the
restriction of positive personal information to friends.
These findings were discussed in terms of the development of
social modesty.

abstract:
The Ghanaian Forests are a significant component of the country’s development.
Occasioned by the rapid population growth of the country, increasing phenomena
such as shifting agriculture, logging, fuelwood harvesting and fire outbreaks have
claimed over 70% of the original forests. The reduction of forests has stimulated the
development of management tools to control forest depletion. In order to focus the
intervention of forest managers and environmental planners, the rate and impact of
forest depletion must be monitored and well documented. Financial constraints and
the lack of adequate maps have hindered the setting up of effective monitoring
mechanisms. This study illustrated the feasibility for using Landsat data and GIS to
map changes in the Ghanaian forest reserves. GIS was used to create the initial
database for the study. Three image analysis change detection methods namely
image algebra (image differencing), spectral temporal and spectral temporal principal
component analysis were employed. The results of the analysis showed that spatial
distributions of the changed areas produced by all three methods were similar,
varying only in the extent. The remote sensing image analysis required the
information stored in the GIS database for rectification and for the assessment of the
classification procedure. A quantitative accuracy assessment was not possible for
the procedures due to limited ground truthing. The use of GPS in field data collection
was demonstrated by its use in delineating the boundary of a selected reserve. The
GPS data was able to adequately display the reserve boundary, the spatial
distribution of Taungya and farms along the boundary as well as relocated boundary
pillars. All new layers of information generated from the research were displayed and
stored in the GIS. Finally, the importance of the outlined procedures in the
monitoring of Ghanaian forest and the limitations of the study were discussed.


title: Role of safe sites in black spruce recruitment and growth release in post-fire Kalmia heath

subject:
Black spruce regeneration

Post-fire black spruce

abstract:
The goal of this thesis was to explain black spruce regeneration in postfire sheep laurel (Kalmia angustifolia L., hereafter referred to as Kalmia) dominated chronosequence in light of safe site density. The concept of safe site was expanded by including germination as well as seedling establishment and growth phases. Proliferation of Kalmia, which dominates heathlands of eastern Newfoundland, has been reported to severely restrict conifer recruitment and growth. As a result, forest regeneration in Kalmia heath can be delayed by as much as 60 years. Despite numerous studies, the process by which colonization and establishment of black spruce occurs in Kalmia heath is poorly understood.
This problem is addressed in two chapters. In chapter one, it was hypothesized that post-fire black spruce stem density, which represents a relative measure of safe site abundance per plot, is a function of variation in microsite conditions, rather than time since fire. The second hypothesis was that the partially safe sites defined by seedling establishment, but poor seedling growth, overtime, become safe sites allowing a growth release. In chapter two, it was hypothesized that microsites created by scarification and microsite mulching (MSM) enhance black spruce growth by removing the inhibitory effects of Kalmia and its organic matter by increased decomposition and soil moisture.
The main findings of the research are (1) black spruce safe site density in
post-fire sites is low and diminishes over time; (2) relative safe site density is negatively associated with organic matter thickness; (3) most of the recruited black spruce experience a period of stunted growth; (4) with time, stunted black spruce may overcome the growth check; (5) the likelihood of the growth release has an inverse relationship with OM thickness and positive relationship with OM decomposition; (6) young black spruce seedlings planted in artificially created safe sites show significantly higher growth rates compared to those in undisturbed heath. Based on these results, it was concluded that i) safe sites play a critical role in colonization and growth of black spruce, ii) high OM depth
(> 5 cm) makes a microsite unsafe for black spruce regeneration, and iii) safe sites created by scarification and microsite mulching (MSM) can enhance black spruce regeneration in Kalmia health.                                                                                By examining the problems of black spruce forest regeneration in Kalmia
dominated sites, this study advances the current understanding of the safe site concept and its application in forest restoration. From the conceptual point of view, it revealed the need for extending the  safe site concept beyond the germination stage to include seedling and adult life stages. This research demonstrates that by removing the growth limiting conditions, it is possible to create safe sites by scarification and MSM which enhance conifer growth in habitats that are otherwise unsuitable for conifer regeneration. For national parks and other conservation areas MSM is preferred to scarification for its minimum soil disturbance.

abstract:
Sexual assault and general violence towards women have been established as major issues in
which feminists are involved (Hermann & Stewart, 1994). Through the use ofmock jury trial
methods, it has been found that some characteristics of sexual assault survivors have an impact
onjury decisions (Pollard, 1992). This study used a mockjury paradigm to explore attitudes
toward sexual assault and sexual harassment complainants who are identified as feminists. Forty
two male and 51 female students were randomly assigned as a mockjury to conditions in which
the complainant in sexual assault and sexual harassment scenarios was either identified as a
feminist or was not. Being identified as a feminist did not affect attributions of guilt and did not
produce more negative stereotypes toward the complainant. In the non-feminist condition, the
complainant in the sexual harassment scenario was likely to be labeled as a feminist by those
who felt she was less credible. These results show that complainants who are labeled as a
feminist are not more likely to be blamed or to be viewed according to negative stereotypes.
However those who are viewed as making frivolous sexual harassment complainants are likely to
be labeled as feminists.

Introduction: Due to the repetitive, high forces and torques placed on an individual during a
baseball pitch, shoulder pain is present in 46-57% of pitchers. Therapeutic taping has been used
in various sports including baseball as it has been proposed to have beneficial qualities in injury
prevention and rehabilitation and performance enhancement via muscular facilitation. Therefore,
the purpose of this study will be to investigate the effect of taping (Kinesio Tape® and no tape)
on the velocity of an overhead baseball throw and muscle activation patterning of the
supraspinatus, infraspinatus, teres minor, and pectoralis major muscles in baseball players after
muscle fatigue has been induced.
Methods: Participants were asked to complete two, 45-minute sessions under two different
taping conditions (no tape and Kinesio Tape®). Participants were asked to complete three pretest maximum velocity overhead throws, a fatiguing protocol, followed by three post-test
maximum velocity pitches while velocity and EMG activity in the infraspinatus, supraspinatus,
teres minor, and pectoralis major muscles were measured.
Results: There was no statistically significant difference in throwing velocity with the
application of the different taping conditions, t(5)=.456, p=.668. There was no statistically
significant difference in tape conditions on the supraspinatus muscle activity in phases one
(t(6)=-1.023, p=.346) , two (t(6)=.172, p=.869), or three (t(6)=-.299, p=.775) of the overhead
throw. There was no statistically significant difference in tape conditions on the infraspinatus
muscle activity in phases one (t(6)=.436, p=.678), two (t(5)=1.66, p=.158), or three (t(5)=.314,
p=.766) of the overhead throw. There was no statistically significant difference in taping
conditions on the pectoralis major muscle activity in phases one (t(5)=.871, p=.424), two
(t(4)=.520, p=.63), or three (t(5)=1.073, p=.332) of the overhead baseball throw.
Conclusion: Based on the results of this study, Kinesio Tape® does not significantly change
muscle activation or velocity of an overhead baseball throw when compared to a no tape
condition. Future research needs to complete testing with a larger sample size to better capture
the effects of taping on surface EMG in the baseball population. Clinicians, baseball players,
baseball coaches, and trainers should consider the possible pros and cons of taping in deciding
whether or not to apply therapeutic taping to the shoulder and the rotator cuff muscles.

abstract:
This thesis reviews factors that affect brook trout (Salvelinus fontinalis Mitchell) fry
emergence and their relevance to population fitness. A series of drift nets were deployed
from 2010 to 2016, April through May, on the Aguasabon River, near Terrace Bay,
Ontario, to capture brook trout fry drifting downstream. Fry were live captured, counted
and released alive each year. The drift nets recorded flow, and nearby data loggers
recorded temperature of the redd. Graphical review of these data was used to determine
any significant relationships between brook trout drift, net flow and temperature. Flow
does not affect temperature, but brook trout fry respond numerically to an optimal
temperature, and high flows encourage drifting. These relationships are described relative
to management of an impounded brook trout spawning stream.


title: Reading tricksters or tricksters reading? An examination of various roles of reading in Thomas King's Green grass, running water

contributor:

subject: Tricksters in literature

abstract:
This thesis explores the Integrative storytelling methods which Thomas King
employs in his novel Green Grass, Running Water. This novel includes and focusses
on oral storytelling methods concerning listener participation, and also on literary
allusions and symbolism, to prompt the reader into an interactive trickster role to make
things happen in discourse.
In order for the reader to understand that he/she has an interactive role. King
must give many different examples of reading and roles of reading and storytelling. I
explore four main roles and character groups in this thesis. The first are the four old
Indians, who exemplify and set the standard for storytelling in this novel; the second is
Coyote, who is a reckless participant, but more importantly a student with whom the
reader can identify; the third group are the characters, Eli, Lionel, and Bursom, who
are realistic readers in relation to the reader’s position - they are most like a reader;
and lastly, the narrator, whose role as a voyeur and non-directive teacher to Coyote
and the reader is consistent throughout the novel. Each of these roles demonstrates
the various levels of oral storytelling and implies a great amount of power to the reader
in his/her role as interpreter and trickster of discourse. To further demonstrate each of
the groups' roles. King has loosely separated the four levels of narrative that each of
these groups inhabit. I am using Genette’s and Rimmon-Kenan’s terminology to
examine the various levels of diegesis and to deconstruct and delineate how the
various characters’ powers in crossing the diegetic boundaries in this novel prompt the
reader into self awareness and push him/her towards a transformative and
interactive reading experience.

abstract:
Height-growth and site-index curves were developed for estimating site
quality of trembling aspen {Populus tremuloides Michx.) in north central Ontario.
These curves were developed from stem analysis data of dominant and
codominant, uninjured aspen trees obtained from 89 plots covering a wide range
of site quality in north central Ontario. The actual height-growth patterns were
modelled using several non-linear biological growth models: Chapman -
Richards function, modified Weibull function, Monserud logistic function and an
expansion of the Chapman - Richard function. In addition, a new height-growth
model was developed using a similar approach to that of Cieszewski and Bella.
Height-growth patterns of aspen varied with level of site-index. Height
growth curves show an almost linear growth pattern for poor sites (SI < 16 m)
to a highly curvilinear pattern on good sites (SI > 24 m). Medium sites (S116-24
m) show a rapid linear surge of height growth before 40 years followed by a
slowing curvilinear pattern.
Height-growth curves, site-index curves and a site-index prediction
equation were constructed from trembling aspen stem analysis data. Goodness
of fit tests were computed using a modified Chi-square test. In addition, the
accuracy of the height-growth curves, site-index curves and site-index prediction
equation were tested using independent stem analysis data from 19 plots
supplied by the Ontario Ministry of Natural Resources. Comparisons with the
independent data source shows close agreement; the 95% site index error
prediction interval for the site-index curves and the site-index prediction equation
are 0.19 ± 1.37 and 0.21 ± 1.35 respectively.

subject: Northern Ontario

abstract:
In recent years, there have been increasingly more protected areas established as an attempt to preserve the biodiversity of coastal and terrestrial ecosystems. In Canada, government agencies have set a goal to protect 12% of natural areas by creating protected areas such as national parks, marine protected areas, national wildlife areas, marine wildlife areas, and migratory birds sanctuaries. Recently, in Ontario, the first national marine conservation area (NMCA) was established on the north shore of Lake Superior. The National Marine Conservation Areas (NMCA) Program is designed to protect and conserve a network of areas representative of Canada's marine environments for the benefit of present and future generations (Parks Canada, 2006). Aside from the obvious benefits of protecting areas of significant biological diversity, research has documented the negative and positive impacts of protected area development on local communities: conflicts over land rights, different understandings of the relationship between people and protected areas, the preservation of natural communities, and the protection of historical and cultural resources.
The purpose of this study was to investigate the opportunities and constraints associated with tourism in protected areas as perceived by the affected community stakeholders in communities adjacent to the newly established Lake Superior National Marine Conservation Area (LSNMCA). Five themes have emerged: sense of place, trust/relationship with senior
levels of government, recreational and traditional importance of the region, views of tourism and development and fear. The participants identified several opportunities and constraints. The opportunities included utilizing the natural resources and landscape of the area, increasing investment in recreational activities in the area, and developing tourism. The constraints included a complex relationship with the government, legislation and policies, a traditional bureaucratic approach to management, and a lack of funding. Since the LSNMCA initiative was first introduced, local attitudes have positively changed towards potential tourism development in the area.

Stroke and intra-limb coordination

abstract:
Stroke results in substantial difficulties in reaching and grasping actions, which may
emerge at different levels of coordination and control, in both the spatial and temporal domains.
In the context of motor control, these issues relate broadly to the Degrees of Freedom Problem
(Bernstein, 1967), as well as to many other theoretical models (e.g., Models of Constraints) that
fall under this conceptual umbrella. Over the last few decades, a substantial amount of studies
have been published to examine these issues, including various systematic reviews. However, the
majority of this work failed to explicitly address the level at which these issues occur, the impact
of different constraints on the emerging patterns, and the conceptual relevance of the emerging
inferences. As such, the purpose of this study was threefold. The first purpose was to examine
whether the selected studies examined the issue in coordination and/or control, and to determine
the conceptual framework underpinning these investigations. The second purpose was to
delineate which individual, task, and environmental constraints have been examined in previous
work, and infer the degree to which these factors affected the nature of the emerging movement
trajectories. Lastly, the third purpose was to address the methodological aspects of the existing
studies, by identifying the prevalence of different measures of coordination (angle-angle plots;
correlations) and control.  [...]

abstract: The purpose of this study was to frame success for Indigenous students in public boards in the experience, knowledge and beliefs of practicing Indigenous educators. Seven Indigenous public school educators in teaching and leadership roles were asked to discuss what success for Indigenous students meant to them. Through a relational, narrative interview process, a cohesive focus emerged on holistic views of education and success, the importance of non-Indigenous teachers' engagement with multiple Indigenous perspectives, particularly those of their own students and their families, and the centrality of trusting, interconnected relationships between teachers, students, and families. The findings are practical and directly applicable due to the educator-to-educator design of the study, and are also contextualized within Indigenous models of success (Canadian Council on Learning, 2007, 2009; Toulouse, 2013). It is noteworthy that Indigenous educators focused on designing public education through Indigenous worldviews and pedagogies to benefit all students. This study is significant in its ability to illuminate a broader view of success in public education as well as to provide specific examples to build this holistic success.

Lightweight networks

abstract:
Monocular depth estimation is a challenging but significant part of computer
vision with many applications in other areas of study. This estimation method aims to
provide a relative depth prediction for a single input image. In the past, conventional
methods have been able to give rough depth estimations however their accuracies were
not sufficient. In recent years, due to the rise of deep convolutional neural networks
(DCNNs), the accuracy of the depth estimations has increased. However, DCNNs do
so at the expense of compute resources and time. This leads to the need for more
lightweight solutions for the task.
In this thesis, we use recent advances made in lightweight network design to reduce
complexity. Furthermore, we use conventional methods to increase the performance
of lightweight networks. Specifically, we propose a novel lightweight network architecture which has a significantly reduced complexity compared to current methods while
still maintaining a competitive accuracy. We propose an encoder-decoder architecture
that utilizes DiCE units [47] to reduce the complexity of the encoder. In addition, we
utilize a custom designed decoder based on depthwise-separable convolutions. Furthermore, we propose a novel lightweight self-supervised training framework which
leverages conventional methods to remove the need for pose estimation that current
self-supervised methods have. Similar to current unsupervised and self-supervised
methods, out method needs a pair of stereo images during training. However, we
take advantage of this need to compute a ground truth approximation. Doing this
we are able to eliminate the need for pose estimation that other self-supervised approaches have. Both our lightweight network and our self-supervised framework reduce the size and complexity of current state-of-the-art methods while maintaining
competitive results in their respective areas.

abstract:
A nursing shortage is looming in Canada (Canadian Nurses Association, 1997, November 4). It is
inperative that as many students graduate from nursing school as possible in order to alleviate this
problem. This purpose o f this study was to discover the reasons for student attrition in a
Canadian Baccalaureate School of Nursing. Tinto’s model o f college student attrition was
applied as the conceptual framework. A Nursing Student Attrition Survey was completed by
forty student persisters and nineteen student leavers. Comparisons between the two samples
revealed significant differences in that older students, students from urban areas, and students
whose mothers and fathers had less post-secondary education were more likely to leave the
program of study prior to graduation. The same was found true for students with lower level
intentions, goal and institutional commitment, and students with more external commitments.
Students persisters were found to feel better about their academic performance and felt that they
had more positive peer group interactions than did the student leavers.

abstract: The objective of the current research was to examine the potential influence of fertility status across the phases of the menstrual cycle (MC) on women’s romantic relationship dynamics. Specifically, women’s feelings and perceptions of interpersonal closeness, relationship and sexual satisfaction, commitment, investment, extra-pair attraction, attitudes toward infidelity, and self-perceived mate value were examined. In order to carry out this study, 20 pair-bonded naturally cycling women and 32 pair-bonded women currently using some form of hormonal contraception (HC) from Lakehead University and the general community of Thunder Bay were recruited to take part in the “Relationship Satisfaction Study.” A within-subjects design was used to examine significant changes across romantic relationship variables between a high fertile phase (i.e., periovulatory phase) and a low fertile phase (i.e., mid to late luteal phase) of the MC. During the periovulatory phase, naturally cycling women also used midstream urine test strips to confirm the presence or absence of ovulation. Naturally cycling women were found to rate the appeal of alternative dating/relationship partners as significantly greater (i.e., greater extra-pair attraction) during the periovulatory phase; however, this only occurred for women who reported that their partners were lower in mate value. Moreover, a significant main effect of MC phase on self-perceived mate value was discovered, such that naturally cycling women during the periovulatory phase rated themselves as more desirable than during the mid to late luteal phase. These results are consistent with previous research regarding women’s dual mating strategies and further contributes to our knowledge regarding purported hormonally-mediated MC phase shifts in the context of romantic relationships.

abstract:
Several genera of bacteria were isolated from the foliage,
twigs, bark and wood of stems of chlorotic 10 - 12 years old white
spruce (Picea glauca (Moench) Voss).
Most of the isolates were nonspore-forming, aerobic or
facultative anaerobic rods. Ninety-four percent of all isolates were
gram-negative and six percent gram-variable. From 16 isolates, five belonged to the genus Enterobacter (Erwinia), four were Serratia spp., three Pseudomonas spp. and two isolates resembled the genus Pasteurella. Two isolates could not be classified.
The bacteria were found throughout the entire trees, but
qualitative and quantitative differences existed between sections of the
trees. The number of bacteria varied from 2.3 X 10[superscript3] to 6.0 X 10[superscript5] / g.d.w., higher concentrations being present in the fine roots and brown spots of bark.
Inoculations with the selected bacterial isolates, alone or in combination, induced pathological responses on young germinants and
rooted cuttings of white and black spruce. Stunting, discoloration, localized
swellings, tip necroses of hypocotyl, reduced root growth and needle
deformation were induced by dip inoculation of seed and hypocotyl.
When the inocula were applied to green cuttings the rooting of cuttings
and the number and length of developing roots were significantly reduced.  Re-isolations yielded the original bacterial types used for the inoculations.
The observed pathogenic effects were consistently associated
with the Enterobacter isolates and one unknown isolate (U[subscript1]). The pathogenicity tests showed that many of the bacteria inhabiting white spruce have the capacity to affect the growth and development of young roots of black and white spruce and thus plausibly to contribute to the chlorosis syndrome of white spruce.


title: Comprehensive Ontology Design for Autism Spectrum Disorder

subject:
Autism spectrum disorder
Ontology

abstract:
Ontology is a formal explicit description of concepts in the knowledge domain. In recent
years, developing ontology in different domains is a hot topic for many researchers, especially in
the medical field because of the benefits offered to users. Using ontology allows sharing and
reusing domain knowledge in an efficient and explicit way. In particular, ontology in medical
field can facilitate the access to query data, precise knowledge, and seamless sharing of
electronic medical records (EMR). Thus ontology increases the accuracy of doctor’s diagnostic
decision.
Autism Spectrum Disorder (ASD) often presents with difficulties in verbal and nonverbal
communication, behavior and social interactions. Autism is difficult to define due to the
complex heterogeneous disorders in this domain and to the lack of coherent set of knowledge
that deals with all aspects of autism. The purpose of this research was to address these
shortcomings by developing a comprehensive ASD ontology that formally conceptualizes both
domain and operational autism knowledge, unifies autism terminology, and facilitates access to
precise autistic information for both general public and expert users, thus enabling better
diagnostic and treatment decisions.
To build such ontology, we investigated many medical research works in the various
areas of autism such as disorders, effects and treatments of ASD. The study was done with the
purpose of extracting and gathering information from the most trusted sources such as existing
ontologies, standard textbooks, relevant articles and clinical studies. These sources were used to
build a semantic map linking key concept classes. Mainly we focused on properties and
relationships between these classes to formally describe the autistic domain and operational
knowledge and to bring the scattered knowledge into the ontological form. Ontology
instantiation for each subclass was based on pilot studies and clinical cases.
The system was implemented using Protégé, an ontological framework developed by the
Stanford Center for Biomedical Informatics Research at the Stanford University. The ontology
was built using the Web Ontology Language (OWL). OWL is a semantic web language designed
to indicate the rich and complex knowledge of the domain. Moreover, we developed a basic web
query system for the ASD ontology to present the ontology information to different users around
the world. The developed system has been evaluated to measure quality of embedded
knowledge, ontology correctness and the usability of its web query system.
