abstract: Study group : 4 teachers at the primary-junior level in 2 elementary schools in Northwestern Ontario.

abstract:
This study begins with questions about teachers’ beliefs regarding classroom
management and the importance of investigating this aspect of teaching. Qualitative
research methods are utilized, including semi-structured and taped interviews, informal
and formal observations, and field notes. Four teachers at the Primary/Junior level
represent the participants. Data collection took place at two elementary schools within
one school board in Northwestern Ontario. Data analysis and interpretation were ongoing
throughout the research process.
The findings reveal that the participants believe in respect, and the notion that
students’ needs must come first. They have developed their beliefs about classroom
management through life experiences, professional reading, and professional
development. Above all, classroom experience has shaped their beliefs and developed
the strategies they currently use, which are as varied as the situations require them to be.
Aspects o f their beliefs and strategies about classroom management have changed since
they began teaching. Participants identified change as being a necessary part of becoming
an effective classroom manager, whether it occurs as a result of learning experiences, or
gaining knowledge through professional development.


title: Best practices of five Canadian ecological education (ECE), environmental education (EE) and education for sustainable development (ESD) pre-service teacher educators

subject: Teachers (Training of Canada)

subject: Environmental education (Teacher training)

abstract: This study examines the teaching practices of five Canadian pre-service teacher educators in ecological education (ECE) courses, environmental education (EE) and education for sustainable development (ESD) courses. This study builds upon Lin's (2002) and Towler's (1980) studies by investigating the varied practices of Canadian ECE/EE/ESD teacher educators through the use of interviews. This study found that to greater and lesser extents, all of the participants use action projects, creative/critical approaches, experiential approaches, modeling, narrative, social learning, present multiple perspectives and provide students freedom in choosing their assignments. These teaching practices are carried out in order to provide an environment conducive to inner transformation.


title: An analysis of the perceived effects of Indigenous spirituality on substance use recovery in Northwestern Ontario

subject: Indigenous spirituality

subject: Addiction treatment using Anishnawbe culture and spirituality

subject: Effects of spirituality (substance use treatment)

abstract:
The purpose of this study was to understand the perceived effects of Indigenous
spirituality on healing from substance use in Northwestern Ontario. This study was based on the
work of Dilico Anishinabek Family Care, a Thunder Bay organization actively involved in
addiction treatment using Anishnawbe culture and spirituality. Semi-structured interviews were
conducted with nine Indigenous participants to understand the perceived benefits of spirituality
in addictions recovery. These participants were either currently using substances, or had a history
of substance use but were in recovery and had taken part in treatment at Dilico. Recruitment
utilized advertisements and a snowball sampling method. Traditional spirituality was perceived
to be important in healing from substance use. This importance was predominantly relational, as
participants described building connections to the self, to the Creator, and others. Additionally,
participants identified the COVID-19 pandemic and housing instability as significant barriers to
practicing their spirituality and thus, carrying out their recovery plans. Participants also described
that living off-reserve limited their ability to access certain ceremonies, medicines, or practices.
These findings have implications for considering tailored treatment for Indigenous adults seeking
treatment for substance use difficulties.

abstract:
Site index of white spruce (Picea glauca (Moench) Voss) in North
Central Ontario was related to features of soil and topography using both
multiple regression techniques and principal component analysis. Two
different measures of site index, TOTSI25 (site index is total height at
total age of 25 years) , and BHSI15 (breast height site index is total
height at 15 years breast-height age) were used as dependent variables; 81
soil and topographic values were independent variables considered for
analysis. Preliminary regressions computed from 54 plots indicated poor
relationships between TOTSI25 and soil and topographic variables.
Preliminary regressions also indicated that the correlations were much
stronger using BHSI15. Correlations also were much stronger when the plots
were stratified into three landform types as opposed to unstratified
regressions. Three final regression equations were based on the
relationship between BHSI15 and lacustrine, morainal, and glaciofluvial
landform groups, and explained 77, 73, and 65 percent of the variation in
BHSI15, respectively. The final regression equation for the lacustrine
landform included the type of clay deposit (CLAY) , the depth to a root
restricting layer (DRRL), and the hue of the C horizon (HUEC). The final
regression equation for the morainal landform included the natural
logarithm of the depth to a root restricting layer (LNDRRL), and the pH of
the C horizon (PHC). The final regression equation for the glaciofluvial
landform included the drainage class of the soil (DRAIN). The ability of
the final regression equations to predict BHSI15 was tested on 14
independent test plots; these tests showed close agreement between actual
site index based on stem analysis and site index predicted from the
regression equations.


title: Insights into gambling : perspectives from self-identified problem gamblers

Compulsive gamblers

abstract:
This study examines the issue of public gambling behavior from the perspective of six
self-identified gamblers. All six participants were assessed to ensure that evidence of
pathological gambling was present. In depth interviews were conducted with each respondent
and the data was compiled and compared. The sample size is small due to the qualitative nature
of this research and as such, the results are exploratory and preliminary. Findings from this study
suggest that treatment approaches that focus on individual behavioral changes of the problem
gambler may have limited effectiveness. The nature and etiology of problem gambling appears to
be embedded and sustained in the extended family friend network. A substantial finding within
this qualitative study is that family pressure, family participation, family encouragement and
family introduction to gambling has an impact on whether or not a gambler develops and
maintains a gambling problem. Hence, this study supports other research findings for a
biopsychosocial approach to gambling behavior. Furthermore, findings indicate that these
problem gamblers see no need to seek treatment which confirms the need to look at the
biopsychosocial approach within an environmental context where decisions are made about the
type, extensiveness and accessibility that society has to gambling opportunities. Government
support for gambling as a significant revenue generator in this neoconservative era where the tax
base is dwindling due to a complexity of factors such as aging population, technology replacing
labour, and the decoupling of taxable capital assets from profits may prove to have many
unintended consequences.


title: Comparison of two treatments for math anxiety : rational emotive therapy and relaxation therapy

subject: Mathematics Study and teaching Psychological aspects

subject: Rational-emotive psychotherapy

subject: Relaxation

abstract:
The purpose of this study was to compare the effectiveness
of two treatments for alleviating math anxiety, rational emotive
therapy and relaxation therapy. Thirty-eight subjects were
randomly assigned to three groups; rational emotive therapy,
relaxation therapy and a no treatment control. At the end of
three weeks, the data of the thirty subjects left were analysed.
Three different types of measures were taken to examine how the
treatments affected the subjects. These measures were selfreport
(Mathematics Anxiety Rating Scale and State-Trait Anxiety
Inventory), performance (answering taped math questions) and
physiological (heart rate). The rational emotive therapy group
was the only group to show an improved score on the self-report,
MARS test after treatment. The other measures showed no
significant differences between treatment groups. The results
were consistent with other studies showing RET to have the
greatest effect on self-report measures of anxiety. The
treatments were equal in clinical usefulness for treating math
anxiety since there was no difference between any of the groups
in performance.

abstract:
Biped robots have many advantages than traditional wheeled or tracked robots. They have better mobility in rough terrain and can travel on discontinuous path. The legs can also provide an active suspension that decouples the path of the trunk from the paths of the feet. Furthermore, the legs are able to step over considerably bigger obstacles compared to wheeled robots. However, it is difficult to maintain the balance of biped robots because they can easily tip over or slide down. To be able to walk stably, it is necessary for the robot to walk through a proper trajectory, which is the goal of this research. In this research, a complete 7-DOF biped walking trajectory is planned based on human walking trajectory by cubic Hermite interpolation method. The kinematics and dynamic model of the biped are derived by Denavit-Hartenberg (D-H) representation and Euler-Lagrange motion equations, respectively. The zero moment point of the robot is simulated to check the stability of the walking trajectory. The setpoint sampling method and sampling rate for trajectory tracking control are investigated by studying sinusoidal curve tracking on a single link robot arm. Two control
sampling time selection methods are introduced for digital controllers.
A 7-DOF biped is designed and built for experiments. Each joint has its own
independent microcontroller-based control system. PD controllers are used to control the
biped joints.
Simulations are performed for the walking trajectory and zero moment point.
Simulation results show that the walking trajectory is stable for the 7-DOF biped.
Experiment results indicate that the sampling time is proper and the PID controller works
well in both setpoint control and trajectory tracking. The experiment for the marching in
place shows the trajectory is stable and the biped can balance during the marching process.


title: Understanding patterns of pleasure craft tourism in the Canadian Arctic and implications for safety management

Dawson, Jackie
Lemelin, Harvey

subject:
Arctic tourism
Pleasure craft tourism
Small vessel safety

abstract:
This study establishes an understanding of pleasure craft tourism patterns in the
Canadian Arctic from 1990-2013 with a focus on the implications for safety. Two
specific objectives were fulfilled: 1. to develop an understanding of the pleasure craft
vessel traffic and pleasure craft travel patterns, and 2. to develop an understanding of
incidents, close-calls, and safety issues.
Pleasure craft tourism in the Canadian Arctic is a relatively new industry,
although it is now the fastest growing marine sector. There is a lack of information on
these small vessels compared to larger expedition cruise ships that have been the focus
of research and management concerns. The increase in pleasure craft traffic in the
region should raise concern about traffic patterns and safety of these tourists because they are traveling in a region with limited infrastructure, services, and search and
rescue. Other issues that need examination are behaviour, monitoring, and control of
pleasure craft vessels, indicating the need for insight into vessel numbers, spatial
patterns, and vessel preparedness.
A literature review was conducted to identify the current state of pleasure craft
tourism in the Canadian Arctic. This included identifying patterns of vessel traffic,
defining pleasure craft and the management context, as well as the management context
of Antarctica and the European Arctic. The literature review concludes with the
knowledge gaps related to pleasure craft tourism that drive this study.
This research takes a quantitative approach to understanding pleasure craft
vessels in the Canadian Arctic. This study uses two main sources of data: the Pleasure
Craft Dataset, developed specifically for use in this project; and, a database of Internet
web logs (Blog File) gathered for this research. The Pleasure Craft Dataset is comprised
of information on pleasure crafts extracted from the NORDREG database (for the
purposes of this research called the NORDREG pleasure craft data), a publicly available
database collected by the Canadian Coast Guard, and data on additional vessels found
through a literature review and Internet searches. The first phase of this study involved
the analysis of the Pleasure Craft Dataset to explore spatial and temporal patterns. The
second phase of this study used content analysis on blogs with material focusing on the
experiences of pleasure craft travelers in the Canadian Arctic.
The results show an increase in pleasure craft tourism in the Canadian Arctic,
and a concentration of vessels and vessels days spent in the Northwest Passage while
demonstrating that not all vessels are reporting to NORDREG. Further, vessels days are
now greater on a per vessel basis than in the past. The results also indicate an increasing
number in pleasure craft travelers overall and the advent of larger pleasure craft vessels
to the region. Blog analysis was able to provide insight into pleasure craft travelers and
their vessels, including aspects such as: sites visited, behaviour of travelers, and
interactions with the environment. The increase in vessel numbers, larger pleasure craft
vessels in the region, and the spatial extension of vessel presence presents issues for management in the Canadian Arctic regarding growing pressure on infrastructure,
services, and search and rescue.
There is a need for further research on pleasure craft tourism in Arctic Canada.
Additional research should contribute to this sector of marine tourism by focusing on
understanding management implications related to safety, insurance, behaviour
controls and monitoring. There is also a need for research into pleasure craft tourism
experiences, the views of community members on the sector, and the role of individuals
who provide support to pleasure craft tourism formally and informally. There is also a
need for policies and guidelines to aid pleasure craft travelers, and quite possibly a
need for mandatory pleasure craft reporting to ensure appropriate monitoring and
support.

abstract: The mobilization hypothesis (Andzel & Gutin, 1976) states that starting a performance with an elevated baseline oxygen consumption will improve performance by reducing the oxygen deficit at the beginning of the task, allowing for greater anaerobic capacity at the end. The purpose of this study was to examine how recovering to different percentages of heart rate reserve (HRR) and oxygen consumption reserve (VO2R) after a warm-up influences running performance in distance runners. Two research questions were developed: how does recovering to 50% HRR vs. 35% HRR after a warm-up influence run to exhaustion performance, and do % VO2R and % HRR decrease similarly when recovering to 35% and 50% HRR. Sixteen trained middle- and long-distance runners were recruited from the Lakehead University varsity track- and-field team and the Lakehead Athletics Club. Testing was completed over three sessions. First session involved treadmill accommodation and VO2max testing. The second and third sessions involved performing a warm-up followed by recovering to either 35% or 50% HRR before completing the performance of running at 105% vVO2max with 1% grade until exhaustion. Paired samples t-test found no significant differences in run to exhaustion time [t (15) = -1.016, p = .326] after recovering to either 50% HRR or 35% HRR. One-sample Chi-square goodness-of-fit test found values of %VO2R were significantly lower than the expected values for both 35% and 50% HRR recovery trials (p = .000, for both trials). In conclusion, participants may have been too close to baseline measures to facilitate the mobilization hypothesis. Alternatively, both trials may have been elevated sufficiently but there was no significant difference between the trials. % HRR and % VO2R were not equal during recovery, but this was likely impacted by the intensity of the stride (15-seconds at 105% vVO2max). Further research into the methods used to warm up prior to long-duration performance is recommended.

In this thesis we conduct an examination of pyramidal elements and their use as interface,
or mortar, elements in the joining of tetrahedral and hexahedral elements in three dimensional
finite element meshes. Several new sets of basis functions are developed and analyzed for
pyramidal elements having five, thirteen and fourteen nodal points. These basis functions take
advantage of the symmetries of the element in order to give improved accuracy over
previously studied basis functions. Evidence of this improvement in accuracy is presented in
the form of numerical experiments.

abstract:
Urban street trees provide many ecosystem services, environmental and
economic benefits for residents, communities, cities, and municipalities. The economic
benefits of trees are not easily quantified as they have no market value. Since 2011, the
bronze birch borer, a specialist wood-boring beetle, has been a pest of birch trees in
northern Ontario. A street tree inventory of streets east of Vicker’s Park in Thunder Bay
was completed to determine the economic value and annual contributions of the birch
trees in this area. To determine the value of the trees, the basic method was used. To
calculate annual contributions the i-Tree MyTree benefits calculator was used. The cost
of removal and replacement were also determined. Using this data, and assuming all
trees would become infested and killed, an economic analysis was completed to
determine which of 100% treatment, partial treatment, or removal and replacement was
most economically feasible. None of the examined scenarios yielded positive results,
however, the most cost-effective solution was 100% treatment of the birch trees.

abstract: The introduction of invasive, non-native earthworms into forest ecosystems has increased as recreational, industrial, and commercial activities increase in northern Ontario. The presence of these ecosystem engineers in previously uninvaded ecosystems has resulted in significant changes in soil structure, vegetation communities and soil organic carbon. In this study, field activities gathered samples of earthworms and soil from five different sites in the Thunder Bay district. Lab analysis was then completed to determine the relationships between ash-free dry mass of earthworms, total organic carbon, soil texture, pH and understory species richness. Results indicated that the presence of earthworms in northern boreal hardwood forest ecosystems has led to significant decreases in carbon storage of approximately 7%. This reduction in soil carbon storage may result in an increased release of carbon emissions and the reduction of the efficacy of the boreal forest as a critical global carbon sink.


title: Stories of practice : preservice teachers' perceptions of information and communications technology

subject: Student teachers.

abstract:
This thesis investigates the perceptions of information and communications
technology (ICT) held by four preservice teachers as they engage in their first field-based
practicum. Perceptions result from interactions between the participants’ educational
beliefs about ICT and their field-based experiences with it. The research was conducted
using qualitative research techniques derived from narrative and collective case study
methodology. Questionnaires completed prior to the practicum, journal entries created
during the practicum, and open-ended interviews conducted immediately after the
practicum, provide contextualized biographical and narrative data.
         Within-case analysis of the data resulted in the production of four individual case
vignettes that reveal the significant experiences and prevailing beliefs of each participant.
The narrative accounts render the participants’ perceptions available and comprehensible
to the reader. A cross-case analysis explores themes that hold across the four cases. It
indicates that preservice teachers conceive ICT in terms of its perceived educational
value and their perceived capacity to use it. These findings, it is suggested, can enlighten
initial teacher education programs by informing theory, by informing practice, and by
informing future research.

abstract:
This qualitative study investigated the experiences of Female Brazilian international
students studying in Canadian post-secondary institutions. While funds and research have been
invested in the promotion and marketing of post-secondary institutions to Brazilian international
students, little or no research has been conducted regarding the cultural accommodations and
needs once they attend these institutions. This phenomenological study examines the experiences
of eleven female Brazilian international students between the ages of 26 and 43 who had
previously completed post-secondary education in their own country. Eleven unstructured
interviews, yielded six themes from a grounded theory analysis process: (a) the Competitiveness
of the Immigration Process; (b) the Adjustment to Living in Canada; (c) the Challenges of
Studying in Canada; (d) Financial Issues; (e) Employment in Canada; and (f) Personal
Wellbeing. The overall benefits and challenges of studying in Canadian post-secondary
institutions are presented and recommendations are made describing specific ways in which
institutions can adapt policies and programs in order to enhance international students’ transition
to Canada.


title: Projectile point assemblage variability at the Paleoindian Mackenzie 1 site, near Thunder Bay, Ontario / by Samantha Markham.

subject: Projectile points Ontario, Northwestern

subject: Paleo-Indians Ontario, Northwestern Antiquities

subject: Indians of North America Ontario, Northwestern Antiquities

abstract:
The Mackenzie Sites appear to form part of the Late Paleoindian Lakehead Complex that
occupied the unglaciated peninsula between Glacial Lakes Agassiz and Minong at the end of the
Pleistocene. While a number of archaeological sites and isolated Plano finds have been made
throughout the region, most excavated collections are from large-scale quarry workshops, and
have yielded vast assemblages of lithic debitage with comparatively few diagnostic tools. In
contrast, the Mackenzie 1 (DdJf-9) site appears to be an extensive and repeatedly used stream
mouth habitation place exhibiting a range of stylistic influences represented in the projectile
point assemblage. Contrary to conventional wisdom, this thesis will utilize an attribute analysis
approach to typological analysis that will permit identification of significant patterned variation
of the 380 projectile points recovered, which will challenge or support the definition of the
Lakehead Complex and Interlakes Composite. The assemblage consists of 53 complete points,
116 basal fragments, 80 midsections, 116 tips, 5 points that were reworked into scrapers, 5 chisel
shaped specimens, and 5 that appear pseudo-notched.
The assemblage is made up of a wide range of materials, but the majority of projectile
points are created from the locally available Gunflint Formation (taconite). Hixton Silicified
Sandstone, Knife Lake Siltstone, and Hudson’s Bay Lowland Chert are also present in minor
capacities. The surprisingly large assemblage of 380 projectile points will in turn enable more
credible comparison to late Paleoindian projectile point typologies developed in other regions.
The attributes that were chosen for the analysis were focused on the projectile point basal
configuration, specifically the bottom third of the specimen. While the functional requirements
associated with arming a spear with a sharp stone tip are rather generic, most projectile points
exhibit a comparatively narrow range of culturally mediated attributes that reflects both ‘functional’ considerations coupled with ‘stylistic’ choice. The combinations of attributes,
therefore, are thought to reflect the cultural ‘rules’ or parameters of what archaeologists suggest
the artisan imagined to constitute a suitable tool form. Taxonomically recognized variability in
tool form sometimes represents temporally and geographically defined variation that is thought
to be diagnostic of the various cultural sequences reported across North America. As a result of
this rationale, the primary traits chosen to taxonomically characterize the projectile points
centred on the morphological shape of the basal configuration; lateral edge shape and basal
concavity. Secondary traits on the projectile points include attribute states associated with
flaking pattern, cross section and the frequency/degree of lateral and basal grinding. These are
considered secondary traits in this analysis because they do not directly influence the
morphological variability of the projectile points, but add another layer of detail suggestive of
the original decision-making process. Particularly compelling is the strong numeric dominance
of projectile points exhibiting the parallel oblique flaking pattern (99%). This challenging flaking
technique is undertaken upon very challenging raw material, but it does not appear to have any
clear ‘functional’ purpose. Nonetheless, its numeric dominance demonstrates that it represents an
important culturally conditioned ‘rule’ evident at Mackenzie 1.

Thjs thesis is concerned with the prelIminary studies in the synthesis of an indolizine alkaloid, slaframine.
A Wittig reaction of 3-carbethoxypropyltriphenylphosophonium
iodide (43) with 4-pentenal (44) gave ethyl-(Z)-4,8-nonadienoate
(45). Hydrolysis of this product gave the unsaturated acid (46) which
was then converted into acid chloride (47), acylazide (48), isocyanate
(49) and finally l-amino-3,7-octadiene (50) . The primary amino group
of (50) was protected by forming trifluoroacetate derivative (51). 1-
Amino-3,7-octadiene was converted in N-(Benzyloxycarbonyl)-3,7-octadiene (52) which was finally converted into epoxide (53).
Other related studies involved: (1) preparation of
1,2-oxidocyclohex-4-ene (54) which was converted into trans-2-azidocyclohex-4-enol (55). The secondary alcohol group was protected by forming acetate derivative (56). A tetrahydropyranyl derivative (57) was also
prepared.

abstract:
Second crop black spruce (Picea mariana (Mill.) B.S.P.) container
stock is often treated with finisher fertilizer after the induction of
budset. The objective of this experiment was to study the effect of
three components of a finisher fertilizer (monoammonium phosphate,
potassium nitrate and potassium sulphate) on bud development, root
development and the induction of cold hardiness in second-crop black
spruce container stock. Fifteen fertilizer treatments were applied to
black spruce seedlings at three private seedling growers in the fall of
1988.
The analysis showed no significant difference in bud and root
development among the fertilizer treatments. However, the fertilizer
treatments may have had a small effect on the induction of cold
hardiness. The hardiest seedlings in the experiment were treated with a
fertilizer high in phosphorus and ammonium. A response surface
analysis indicated that seedling hardiness may be further improved with
fertilizer combinations outside of the experimental region in the
direction of the strongest response.


title: Northwestern Ontario gold mining, 1880-1902 : the gold boom that didn't pan out

format: application/pdf application/pdf

subject: Gold mines and mining Ontario, Northwestern History

abstract:
In 1878, gold was discovered south of Rat Portage on an island in the Lake of the Woods. After
a brief flurry of development, excitement waned and Rainy River District mining progressed
slowly and fitfully for more than a decade. Then, between 1896 and 1902, thousands of
locations were leased or patented and hundreds of mining companies were formed. There is
every indication that something really big was happening in Northwestern Ontario at the end of
the last century. However, with total production amounting to less than $1.5 million, there is also
every indication that nothing big should have been happening.
This study investigates the factors that affected the development of this unusually "unproductive"
gold boom. These include geography, geology, government policies, and "patterns of
development." The research included with this thesis provides details for more than two hundred
and thirty different "mines," two hundred companies, and more than a thousand incorporators and
mine managers. Numerous photographs, tables, and graphs are also included.

Clearcutting

abstract:
In this thesis I examined three important ecological questions to understand the role of forest management disturbance on unmapped small stream riparian plant communities: I) how do small stream riparian plant communities respond to forest harvesting and site preparations?
ii) How do species diversity - functional diversity reiationships vary in disturbed riparian and disturbed upland habitats? and iii) Do riparian buffer reserves act as plant refuges in the clearcut boreal forests?
In chapter 1, I answer the first question by reviewing and synthesizing published (searching ISI Web of Knowledge™ database) and grey literature. I found that small stream riparian plant communities are very poorly studied. Forest harvesting and scarification significantly reduce riparian plant species richness and diversity causing a shift from herbaceous to shrub dominance. I suggest that disturbance along small streams may facilitate the spread of invasive species into the streams that are protected by buffer reserve. I argue that the distribution patterns of plant functional traits might be useful as a predictor in developing an early warning system against habitat degradation.
In chapter 2, I answer the second question by sampling naturally colonized plants along small streams in clearcut, clearcut plus soil scarification, riparian buffer reserve near clearcut, riparian buffer near clearcut plus soil scarification and uncut reference sites. Using 36 sets of functional traits as a surrogate of functional diversity, I test the effects of disturbance on species diversity - functional diversity relationships in two habitats: riparian and upland, I found that both species diversity and functional diversities reach their peak under moderate intensity of disturbance, producing a bell shaped disturbance-diversity curve. The disturbance-habitat sensitivity coupling has very little effect on overall diversity although the effect on particular life forms and functions may be significant. The novel finding in this study is that in natural communities, species-functional diversity relationships are linear in low intensity disturbance but this relationship shifts to curvilinear (quadratic) with moderate to high intensity of disturbance, due to uneven functional redundancy. This finding invokes that the current approach of conservation that predominantly relies on species richness needs to be reevaluated by considering plant functional traits.
In chapter 3, I answer the third question by sampling plant communities around small streams in the clearcuts, the riparian buffer reserves around clearcut and in the uncut reference forests. I used a combination of trait based functional dichotomy and plant cover to predict plant colonization from the clearcuts to riparian buffer reserves. I found that riparian buffer reserves support more species than the clearcuts and the reference forests. In the trait display I was able to show that additional species in riparian buffer reserves were coming from adjacent clearcuts.  This finding suggests that in the boreal forest, riparian buffer reserves act as refuges for plants,
especially in the early stages after clearcutting. This finding invokes that careful management of riparian buffers may help in reducing the local extinction risk of many disturbance-sensitive plants.

abstract:
The North American moose (Alces alces) is a species of socio-economic importance that has undergone recent declines in some areas of its range and may be impacted by climate change through effects on physiology or habitat availability. Moose frequently use aquatic habitat during summer but the timing, frequency and reasons for this behaviour are not well understood and appear to vary geographically. My objectives were to: 1) clarify the importance of aquatic habitat to North American moose through a literature review and 2) estimate richness and biomass of submersed and floating-leaved vegetation in lakes and beaver ponds potentially used by moose
in north-central Minnesota through a comparative field study. The literature suggests that moose use aquatic habitats to feed and escape biting insects and do not appear to use them to escape predators or ameliorate heat stress, though the latter function may be important at the extreme southern limits of moose range. Richness and biomass of aquatic plants in aquatic areas potentially used by moose in north-central Minnesota was heavily influenced by the presence and damming activity of beaver (Castor canadensis). Beaver ponds contained higher richness
and biomass of aquatic vegetation compared to lakes. The creation and maintenance of large (> 1 ha) beaver ponds 6-38 years of age facilitate moose in meeting nutritional demands because they allow growth and reproduction of species less competitive but potentially more palatable than the dominant floating-leaved plant Brasenia schreberi. The maintenance of beaver populations may be important for moose conservation in north-central Minnesota.

tuberculosis, Avian Influenza and severe acute respiratory syndrome (SARS), public
health departments across the country have been challenged with the need to develop
action plans for both treatment and prevention. Yet the problem is not isolated to Canada
but is considered to be a major public health threat both in Canada and internationally.
The emergence of viral respiratory infections in Canada may be attributed to several
sources, which include migration from one part of the world to another either for
pleasure or business, as a major contributor. Such migrations coupled with inadequate
infectious disease prevention strategies not only leads to rapid transmission of respiratory
infectious diseases, but there is also a problem in administering effective treatment and
vaccines to infected cohorts.Several factors contribute to both the accidental and/or
deliberate transfer of microbial agents. For example, economic, cultural and political
interactions invoke the emergence of new and unrecognized microbial disease agents
(Lashley, 2006). New diseases have the potential to spread across the world in a matter of
days, or even hours, making early detection and action more important than ever
(BCCDC, 2008).

abstract: Preservice Teacher Beliefs about Teaching Language and Literacy describes the findings of a qualitative study conducted with a Junior/Intermediate language arts methods course in a Faculty of Education at a University in Northern Ontario. The study was conducted in two phases. The participants in the first phase consisted of one cohort of 39 preservice teachers; the second phase consisted of eight participants drawn from phase one. Data sources included personal history accounts, term reports, reflection papers, lesson plans, learning journals and transcribed focus group interviews. The data were emergent and a constant comparitive method was used for analysis. Phase One findings are presented holistically while Phase Two findings are presented as three case studies. The findings indicated that preservice teachers have multiple assumptions and beliefs about literacy teaching and learning when entering the teacher education program and that these are informed by a variety of influences, prior to their admission to and during their studies in the Bachelor of Education program. Findings also indicate that preservice teachers can identify their entering beliefs when given opportunities to do so and that those beliefs are amenable to change in linear as well as cyclical ways as a result of in-course and across course learnings and experiences and field components of the program as well as through opportunities for reflection.


title: Recategorizing pornography through technocultural change

subject: Pornography Technocultural

abstract: Pornography has long been a subject of great controversy, much disagreement and conflict on intellectual and legal levels. There have been extensive debates on pornography regarding its potential to do psychological harm, its correlations with sexual violence, and its moral properties. Pornography has also been at the forefront of legal debates regarding obscenity, organized crime, pandering, first amendment rights in the United States and freedom of expression in Canada under the Canadian Charter of Rights and Freedoms. Aside from being a controversial topic and source of conflict it is also an increasingly popular form of adult entertainment - one that is becoming more widely accepted North American society.

abstract:
Creativity is becoming an increasingly important aspect of being a successful dancer.
Dancers are now being asked to be a part of the development and choreography of their routines
and performance (Butterworth, 2004; Clements & Redding, 2020; Nordin-Bates & Abrahamsen,
2016). Perfectionism is also another common personality disposition present in dancers. The
present study aimed to examine the relationship between multidimensional perfectionism and
creativity among dancers and to test whether perceived teacher autonomy support moderated that
relationship. A sample of 215 competitive dancers (Mage = 17.17, SD = 1.92) completed
measures capturing variables of creativity (creative self-concept, attitudes and values towards
creativity), 4 subtypes of perfectionism (pure personal standards perfectionism, pure evaluative
concerns perfectionism, mixed perfectionism, non-perfectionism) and perceived autonomy
support provided by their dance teacher in a cross-sectional research design. The findings of two
iterative multiple regression analyses found a positive main effect for personal standards
perfectionism and a negative main effect for evaluative concerns perfectionism in relation to
creative self-concept and a negative main effect for evaluative concerns perfectionism in relation
to attitudes and values towards creativity. These main effects supported all 4 hypotheses of the 2
× 2 model of perfectionism for creative self-concept and supported 3 hypotheses of the 2 × 2
model for attitudes and values towards creativity (H1c, H2, and H4). In addition, neither of the
relationships were moderated by perceived teacher autonomy support. The discussion speculates
as to why relationships were significant for pure evaluative concerns perfectionism across both
relationships and pure personal standards perfectionism was only significant regarding creative
self-concept.


title: Managing for Emerald Ash Borer in the urban forest

subject: Emerald ash borer (Agrilus planipennis Fairmaire)

subject: Ash (Fraxinus spp.)

subject: Trees in cities

subject: Urban forests

subject: Barrie (Ontario)

abstract: Urban forestry is a concept applied to many cities, municipalities, and communities around the world. It is the practice of managing the interface between urban infrastructure and environmental green spaces. An invasive insect known as the emerald ash borer (Agrilus planipennis Fairmaire) has been devastating urban forests in southern Ontario since 2002. Larval feeding on ash (Fraxinus spp) can kill a tree in 3-5 years. Emerald ash borer (EAB) has been moving northward eliminating trees by the thousands, and was discovered in the City of Barrie in 2014. In order to manage for EAB, it is crucial to know where the ash trees are located. The City of Barrie has an inventory of publicly owned trees, but not of those on private property. In addition, the public may not be fully aware of the devastating effects of EAB on the urban forest and the associated management strategies. Obtaining the private ash tree inventory depends on residents to self-report on signs of EAB. Current aerial imagery for the City of Barrie was converted into a format suitable for common smart devices. It can be used as a visual aid in communicating the threat of EAB, and to highlight high risk areas. A pilot project of an urban forest health volunteer network was conducted successfully in the Town of Oakville in 2014. The same process of community engagement and urban forest management was demonstrated through a sample inventory in the City of Barrie. The data combined with the imagery is a crucial aid in developing an early detection rapid response management plan for the City. Future possibilities resulting from this thesis project could be the creation of an online database where members of the public can access the digital imagery, self-report on private trees, and remain informed on urban forest management strategies.

Stem analysis
Two-stage sampling
Computer algorithm & simulation

abstract:
This study examined two topics. In the first, a computer
algorithm was developed to process stem analysis data produced by
Tree Ring Increment Measure (TRIM) system. The algorithm
developed not only processed TRIM data for cumulative increment of
volume, height, and dbh by one-year intervals for individual trees,
but also calculated annual volume increment per unit area (vol./ha)
by one-year intervals for stands. A hashing technique with a linked
list data structure was used in the algorithm. The advantages of the
algorithm are to process stem analysis and manage outputs
efficiently and to provide a user with quick access to any processed
stem analysis tree records. In the second, sampling intensities on
both plot and tree levels were investigated. Two forms of two-stage
sampling strategies were employed. The study indicated that
subsampling using Probabilities Proportional to Size (PPS) could
produce reliable estimates for an annual growth. The study
suggested that over 91 percent of precision of mean growth estimate
can be obtained with the sample plot intensities of 66 percent at the
first stage and with the sample tree intensities of 2.1 percent at the
second stage at the 95 percent confidence level. The study also
showed that subsampling with PPS was superior to that with simple
random subsampling.


title: Hegemonic masculinity : just another day at the gym?

subject: Masculinity

subject: Weight training Sex differences Psychological aspects

subject: Bodybuilding Sex differences Psychological aspects

abstract:
This thesis is an examination of masculinity and gym culture in a regional
Canadian community. Through ethnographic observation and in depth interviews I
explore the ways in which masculinity is Hterally embodied in the gym through
participation in weight lifting and interaction with peers. Drawing on research on
masculinity, sociology of the body, and feminist and gender studies, I examine the
social construction of hegemonic masculinity and the extent to which it influences men's
desires to lift weights as well as how it permeates and shapes the gym environments in
which this activity is carried out. In contrast to earHer social science work which focuses
primarily on elite, urban bodybuilders, this study examines the experience of
recreational weight lifters in two distinct gym settings, "hard core gyms" and
"chromed-up health spas" (or health clubs). Comparisons and contrasts in the
construction of masculinity in these two settings are drawn and data is compared with
the experiences of elite bodybuilders described in the earlier studies.
I argue that the experiences of recreational bodybuilders in a regional Canadian
community are different than those of professional bodybuilders. What links these two
different communities together is how hegemonic masculinity affects the men that
work out. Hegemonic masculinity invades gyms in different ways and therefore affects
the men in these gyms in subtly different ways. I have argued throughout this thesis
that the works of Alan Klein (1993) and Samuel Fussell (1991) are useful and necessary,
however, do not account for the range of experiences that men go through well at the
gym.

abstract: Wireless communications have long since been utilized to connect a multitude of devices quickly and easily to a common network. However, such methods have not yet been implemented inside a Magnetic Resonance Imaging (MRI) environment, leading to a difficulty of implementing simple devices easily and quickly inside the environment, especially in significant numbers. The feasibility of having a network of MRI-compatible sensors is of great interest for image-guided interventions such as MRI-guided Focused Ultrasound Surgery (MRgFUS). MRgFUS will benefit from the collection of multiple data such as temperature, backscattered acoustic waves, among others, for the monitoring of the procedure.

abstract:
Habitat selection in herpetofauna in Rondeau Provincial Park (RPP) around roads and
human structures in built areas were described alongside recommendations on cover
board material for their survey. The first objective was to ascertain differences among
captures between cover board types: 1.5-inch (3.8 cm) thick, but smaller, spruce boards
or 0.5-inch (1.3 cm) thick plywood boards. The second objective was to report on
insights on cover board arrangement for maximum captures and appropriate seasons
for herpetological surveys in the RPP region. A third objective was to determine how
distance to nearest road or distance to the nearest artificial structure might influence
captures. Cover boards were classified by type and frequency of capture across eight
common species in RPP. Significantly higher captures than expected by the area from
which all traps were drawing indicated patterns of selection. The period over which peak
captures occurred was plotted for each species against temperature trends over the
2014 season. Species preferring moist habitats were attracted to a more insulating
board that mimics damp microclimates; those preferring dry habitats were ready to use
a less insulating plywood board. Model selection based on Akaike’s Information
Criterion (AIC) for small samples was used to find habitat associations for five species
with sufficient captures in forest and built areas, distance to the nearest road, and
distance to identified buildings in the cottage development. Roads created a significant
apparent deterrent to the herpetofauna in RPP. As the climate changes, herpetofauna
will be forced to change their activity seasons. The trends illustrated in RPP indicated
that small, cryptic species of lizards could survive anthropogenic disturbance and even
find overnight refuge in anthropogenic areas.

abstract:
The purpose of the study was to investigate recent Chinese immigrants’
perceptions of English language learning and culture learning in a predominantly
English culture during their first three years of settlement in Canada. The design of
the study was qualitative, and the primary methodology was the interview guide
approach. Participants were six Chinese immigrants who settled in Toronto, Canada.
Three themes emerged from the analysis of the qualitative data: Chinese immigrants’
perceptions of their English language learning; Chinese immigrants’ perceptions of
culture learning; and language, culture and life expectations. The findings of the study
support the existing literature and generate new insights into Chinese immigrants’
experiences with English language and culture learning. Finally the study illustrated
that immersion in a predominantly English speaking society is complex in nature and
may be experienced in different ways.


title: Effects of harvest treatments on spruce budworm, Choristoneura fumiferana (Clem.) (lepidoptera: Tortricidae), dispersal within forest stands

subject: Spruce budworm

subject: Spruce budworm control (Ontario Black Sturgeon Lake Region)

abstract:
Dispersal is a critical trait during the life history of
the spruce budworm, Choristoneura fumiferana (Clem.), which
leads to its widespread infestation and damage. Budworm
dispersal study is of importance for protecting and
regenerating valuable white spruce, preferred by the forest
industry. One factor that influences dispersal is forest
density. The objectives of this project were to investigate:
1. the effects of harvest treatments on the larval dispersal
of spruce budworm; 2. the effects of harvest treatments on
the responses of budworm male moths to pheromone traps.
Harvest treatments were set up in two plots near Black
Sturgeon Lake in the late fall of 1993 as follows: one uncut
treatment, one partial cut with white and black spruce left,
one partial cut with white spruce and birch and aspen left,
and one strip clearcut. Spruce budworm egg-mass and larval
densities were determined by branch sampling. Sticky traps
were deployed for small larval dispersal, water traps for
large larval dispersal, and pheromone traps for the responses
of male moths to them in the above treatments during 1994 and
1995.

abstract:
This thesis describes an evaluative case study, which researched the benefits of using the
REACH program in two Thunder Bay elementary schools, eliminating the need to have studentsat-
risk removed from their home school to attend alternative programming. The REACH acronym
stands for Relationships, Environment, Attitude, Co-Regulation, and Holistic Education, and the
program focuses on bringing all of these elements into the school to create opportunities for
students-at-risk to experience success throughout their school day. This study was implemented
throughout the 2017-2018 school year, with the REACH program beginning in the 2016-2017
school year. The participants were teachers, principals and student support professionals, as well
as students and parents who were part of the REACH program and were asked to participate in the
study. Data were generated through interviews and document review of principal case conference
notes, student records, and office referral documents. The generated data were coded into each
section of REACH, further explaining why this program is necessary. The a priori themes are:
Relationships, Environment, Attitude, Co-Regulation, and Holistic Education. Emergent themes
of student relationships and next steps for the program are also discussed within this thesis.

subject:
Hearing loss
Social isolation
Depression in old age
Effects of hearing impairment

abstract:
Earlier evidence was not conclusive about whether hearing
loss is associated with depression and social isolation in
elderly residents. The purpose of this study was to determine
whether functional hearing impairment (FHI) in residents in
complex continuing care facilities is associated with depression
and social isolation (anhedonia, reduced social engagement, and
reduced activity levels).
Results indicate that functional hearing impairment is
associated with symptoms of depression. Residents with FHI have
higher levels of anhedonia. Moderate/severe functional hearing
impairment is associated with reduced social engagement and low
activity level. Path analyses showed that FHI impairs linguistic
communication, linguistic communication results in social
isolation, and social isolation lowers mood. Results also showed
a direct effect of FHI on mood.
This study adds to the literature in support of an
association between functional hearing impairment, depression,
and social isolation. Although this study is correlational, we
propose that functional hearing impairment is associated with
depression because of the social isolation caused by poor
linguistic communication. While only a hypothesis, pre-existing
ailments associated with complex continuing care may also
amplify a sense of social isolation.

abstract:
This thesis is an examination of the commercial mycorrhizal additive known as MYKE®, and the impact upon growth that it has on American elm seedlings grown under greenhouse conditions.
Seedlings of American elm were grown in a plug tray for several months and then transferred into four-inch pots which contained various amounts of the product MYKE®. Ten pots had no product to serve as a control, ten pots had 1 gram, ten pots had 5 grams, and ten pots had 25 grams. These seedlings were grown for another three months under greenhouse conditions with regular watering. Upon being harvested, soil was carefully removed from the roots. The roots and shoots were visually inspected, photographed, and then separated at the root collar and placed into paper bags and dried at 100 degrees Celsius for three days. After drying, the stems and roots were weighed to the nearest milligram and then statistical analyses were performed on the data to see if there were statistically significant differences. The results found that there were no significant differences between the 25 gram and control in the root and shoot, and no significant differences between the 1 and 5-gram trials in the root and shoot measurements. However, there were significant differences between the two groups as illustrated by the LSD test performed. In the combined weights there were no significant differences between the control and 25 gram trials. However, the 1 gram trial was significantly different from these two in addition to the 5 gram trial. The 5 gram trial was significantly different from the control, 1 gram and the 25 gram trial. These results show that this product does work as intended and could assist in growth in an urban environment.

subject:
Black spruce
Trees Ontario, Northwestern
Forest genetics

abstract:
Plus-tree selection of black spruce [Picea mariana (Mill.) B.S.P.)
based on increment of wood volume per unit of crown (growing space efficiency) has the potential to improve yield per hectare and avoid biased
selection of trees that have a competitive advantage in natural stands.
In 1981, and again in 1983, 200 and 400 trees from two 60 year-old upland
black spruce stands located in Northwestern Ontario were scored for
various growth parameters, crown dimensions and competition indices.
Regression analysis showed that the competition indices were poorer indicators of basal area increment (b.a.i.) than the crown parameters.
The crown parameter that best predicted b.a.i. was crown area (c.a.);
r[superscript] 2 values of 0.45 and 0.57 respectively were calculated for the two black spruce stands although the slopes differed significantly. To
test the effectiveness of baseline selection of black spruce based on
the regression of b.a.i. vs. c.a., the top 10 trees were selected from
the second stand by this method and compared to each of the top 10 trees
chosen by a height vs, age baseline method and a purely random method.
Only one tree was selected in common by each of the baseline methods.
Trees selected by b.a.i. vs. c.a. baseline were far more variable in
their size than those selected by height vs. age. Scale drawings and
statistical analysis of the selected trees did not reveal any easily identified
crop ideotype of black spruce plus-trees expressing growing
space efficiency. Wind-pollinated seed of the 29 selected trees was
collected and used to establish a short-term and a long-term progeny
test to investigate heritability of growing space efficiency. The
short-term test was conducted in a greenhouse over one growing season
and included light intensity as a treatment, while the long-term progeny
test was planted in 1984 and included spacing as a treatment.
Discriminant analysis of Marks Lake progeny helped to identify a weak
trend where the tallest progeny came from short-crowned parents. Results
of the short-term progeny test demonstrated strong family differences,
strong family x light interaction, but no selection method
differences. Some of the family differences in the progeny could be
accounted for by the maternal effect of seed weight, although after
removal of this effect by analysis of covariance, still no differences
could be detected between selection methods. Parent and progeny correlations for height and crown features were weak and often negative,
which suggests heritability estimates for characters related to growing
space efficiency are likely to be as low as estimates for growth
in general. The premature results of this study imply that if trees
selected for superior growing space efficiency have inherent advantages
in lower light intensities within mature stands, their juvenile
progeny do not express these qualities. Characters responsible for
growing space efficiency are not heritable or have not yet expressed
themselves.


title: Body condition of gray partridge (Perdix perdix) during fall and winter in Saskatchewan

subject:
Partridges
Birds Saskatchewan

abstract:
During August 1979 to March 1980, 118 Gray Partridge were
collected from a 207[superscript 2] km study area near Tugaske, Saskatchewan.
Temperature and snowpack information were monitored throughout
the study period. Partridge were necropsied, searched for
internal and external parasites, and fat, protein and moisture
determinations conducted for each bird.
Mean monthly temperatures during the study period approximated
the 30 year mean for the area. The winter of 1979 - 80
was characterized by reduced snow depths and a longer snowfree
period than normally occurs in this area of Saskatchewan.
Male and female partridge exhibited a similar seasonal
pattern of body weight fluctuation during the study period. There were no significant differences (P>.05) in mean monthly body
weights of adult and subadult male partridge during August to
March. Female partridge weights increased significantly (P<.05)
from September to January, then declined through to March. Body
weight of male and female partridge attained January maxima of
416 g and 410 g, respectively and are among the highest recorded
in North America. The application of several condition indices
failed to provide more accurate estimates of metabolic reserves
than carcass weight alone.
Lipid reserves appeared to be of significant metabolic importance
to Gray Partridge in Saskatchewan. Among male Gray Partridge,peak
fat reserves (29% dry body weight) occurred in January and among
females, in December (30% dry body weight). There was no significant difference (P>.05) in mean monthly weight of body fat of male
partridge. Body fat increased significantly (P<.05) among females
between September and December. Thereafter, fat reserves in both
male and female partridge declined but not significantly, to the
end of March.
Subcutaneous fat deposits constituted the largest fat reserve
in partridge, comprising 53% and 48% of total body fat in males
and females, respectively. Carcass protein levels in both sexes
were relatively constant during the period of study.
Weight of the abdominal fat depot represented a practical,
easily obtained and relatively accurate predictor of total body fat
reserves, while carcass weight was the best predictor of protein
reserve in Gray Partridge.
Endoparasite and ectoparasite loads were not overly large
among partridge examined and appeared of no significance as a
mortality factor.
The implications of these findings to partridge management are
discussed.


title: Comparison of growth intercept and site index models of black spruce plantations and natural stands in Northern Ontario

subject:
Black spruce (Ontario, Northern Growth)
Polymorphic height growth
Silviculture

abstract:
Black spruce (Picea mariana Mill. B.S.P.) is one of the most important tree
species in Canada, both ecologically and commercially. The forest industry has steadily
increased efforts to artificially regenerate areas that have been harvested resulting in
expanding areas of black spruce plantations. The increase in amount o f area and the
number of trees that are planted requires accurate tools for height and yield estimation in
these stands to ensure sustainable forest management and a dependable future wood
supply. Currently these tools are unavailable resulting in underestimated site productivity
in black spruce plantations by a site index and growth and yield model that was derived
from natural stands.
In this study, 62 sites were sampled across northern Ontario ranging from
Kirkland Lake in the east to Kenora in the west. Within each plot 3 undamaged dominant
or co-dominant trees with no indication o f suppression were felled for stem analysis.
These sites were planted, contained a minimum black spruce composition of 70%, and
were at least 40 years old. Within each plot a soil sample was collected from the C
horizon and relationships between soil characteristics and site quality were examined.
Accurate and precise growth intercept and site index models were developed from
the stem analysis data collected from black spruce plantations. These models were
compared to models for natural stands using Carmean’s (2006) data. Comparison of site
index curves between planted and natural stands showed a significant difference. Planted
stands displayed increased height growth patterns, especially in early breast height ages,
as well as enhanced total height prediction accuracy when compared to natural stands.
These height growth increases may be directly related to silvicultural activities that occur
on productive upland sites.
Soil characteristics from the C horizon were related to site productivity in black
spruce plantations. Soil pH in calcium chloride, elevation, sand, and silt content were
shown to be significant factors. Factor analysis concluded that many soil characteristics,
such as soil pH in calcium chloride, soil pH in water, Ca, Mg, Na and clay content
attributed for similar variances to site quality in terms of site index.
Due to its shallow rooting nature, and previous studies that have shown black
spruce to have a maximum attainable height of 20 to 21 m before becoming susceptible
to windthrow, a rotation age of 60 years on productive upland sites is recommended. In a
300 year scenario, productive upland black spruce sites harvested at a 60 year rotation
produced 223 % more merchantable volume than natural stands. If these stands are not
harvested until 80 years, stands could incur volume losses of at least 30 % due to
windthrow and tomentosus root rot.

abstract:
It would be just as easy to say what this thesis is not about as it would be to say
what it is about. Indeed, some would venture to say that most of this thesis is not about
technology at all, with a paragraph about keyboards here, a footnote about microchips
there, but rather pages about politics, sociology, anthropology, and so on. I would
respond that it is all a matter of definition, and the definition of technology I am
preferring in this thesis extends well beyond keyboards and microchips into the vastness
of all politics, sociology, anthropology, and further still. This position carries with it a
conclusion that technology, as defined, is among the determinants of individual, cultural,
and social change. Admittedly, determinism in any form is considered unpopular, yet
from the beginning of this process I have been given no sufficient reason to think
otherwise.
This thesis represents my own introduction to the philosophy of technology.
Begun from a mere interest, every stage of research, every book, and every article
provided something entirely new. I have tried to align and condense a small portion of it
for this thesis, so the reader should be aware that many, many important thinkers on
technology have been left out. As a result, this thesis, while still being ambitiously broad
in scope for a treatment of this length, represents but a fraction of the held as whole. At
any rate, it tells a story I believe is worth reading, especially in a momentous
technological age such as ours.

abstract:
Voltage-controlled oscillator (VCO) plays a key role in determination of the link
budget of wireless communication, and consequently the performance of the transceiver.
Lowering the noise contribution from the VCO to the entire system is always challenging
and remains the active research area.
Motivated by high demands for the low-phase noise, low-power consumption VCO in
the application of 5G, radar-sensing system, implantable device, to name a few, this research
focused on the design of a rotary travelling-wave oscillator (RTWO). A power conscious
RTWO with reliable direction control of the wave propagation was investigated. The phase
noise was analyzed based on the proposed RTWO. The phase noise reduction technique
was introduced by using tail current source filtering technique in which a figure-8 inductors
were employed. Three RTWO were implemented based on GF 130 nm standard CMOS
process and TSMC 130 nm standard CMOS process. The first design was achieving 16-GHz
frequency with power consumption of 5.8-mW with 190.3 dBc/Hz FoM at 1 MHz offset.
The second and third design were operating at 14-GHz with a power consumption range of
13-18.4mW and 14.6-20.5mW, respectively. The one with filtering technique achieved FoM
of 184.8 dBc/Hz at 1 MHz whereas the one without inudctor filtering obtained FoM of 180.8
dBc/Hz at 1 MHz offset based on simulation.

subject: Menstrual cycle effect on sexual interest & strategies

abstract: Previous research suggests sex differences in mate preferences and mating strategies based on reproductive constraints (Buss, 2005). Furthermore, research has suggested that women's mating behaviours change across the menstrual cycle, with peaks in certain mating preferences and attraction strategies (i.e., short-term strategies) occurring when conception likelihood is highest. A goal of the current study was to develop a measure of flirting and mate attractivity behaviours that would allow for measurement of between- and within-sex differences in these behaviours. The study examined the relationship between gender identity (i.e., masculinity and femininity) and mating strategies, mating strategies in the context of the menstrual cycle, and sex differences in flirting “in person” versus “through technology” in 557 participants (463 women). After controlling for age, social desirability scores, and years of education, masculinity was positively associated with engagement in male-typical mating strategies in both sexes, while femininity was positively associated with engagement in female-typical mating strategies for women only. In women, engagement in overall mate attraction behaviours increased with conception likelihood, however, short-term (ST) mate attraction behaviours did not show stronger associations with fertility than long-term (LT) mate attraction behaviours. Finally, while women reported flirting more in person and through technology relative to men, there was no evidence that women engaged in relatively more flirting through technology than in-person as compared to men. These findings suggest that one’s gender orientation and women’s conception likelihood are associated with the choice and frequency of mate attractivity behaviours, and suggest value in examining within-sex individual difference variables in predicting mate attraction behaviours.

Dying, also referred to as MAiD (CPSO, 2015). This paper will consider the relationship
Christian physicians in Ontario have with the Effective Referral Requirement and the ways in
which they manage their competing values within their profession and their faith. Ultimately this
paper will aim to answer the following research question, “How do Christian Physicians in
Ontario understand the tension between their professional and religious obligations when
considering MAiD?”. To answer this question structured-qualitative interviews were conducted
with eight physicians who a.) identify as Christian, b.) are in a position to receive requests for
MAiD, and c.) practice medicine within Ontario with a license. Thematic analysis was used to
analyze the interview data. Participants suggested several alternatives that they feel would
adequately address their concerns with the Effective Referral Requirement such as the
implementation of a self-referral system and changing the requirement from providing a referral
to requiring the provision of a phone number to patients instead.

abstract:
Flexible-Iink manipulator has many advantages over classic rigid body manipulator in
industrial and space applications. However, it also poses high requirements on controller
design, to ensure the accurate tip position tracking and suppression of tip
deflection/vibration.
This thesis sets up the model, both linear sections and nonlinear sections, for a typical
apparatus. It discusses, by simulations and experiments, the solutions for these control
problems. PD controller plus conditional I control is found elective on rigid body
tracking control, and P controller with second-order lowpass filter proves effective on the
suppression of deflection/vibration. Optimized PIDP controllers are experimentally
implemented and the system performances are shown.
Further this thesis discusses a LQR controller which uses a ninth-order full state feedback.
Experimental results using the LQR controllers show an improvement over the PIDP
controller, particularly in the suppression of flexible beam deflection.


title: Weaving the literary quilt : the layering of narrative in Thomas King's Truth & Bright Water

abstract:
This thesis explores the ways in which Thomas King
layers levels of textual and symbolic narrative in order to
show that truth is a relative concept that cannot be
strictly bound by conventional, essentialist beliefs.
In Truth & Bright Water, Helen creates a quilt that
tells a continually re-interpreted version of both her, and
her community's history. It is only when the reader looks
closely at the details of the quilt in conjunction with the
textual details of the novel that the reader is able to
come to any understanding of the novel. In keeping with
King's theory of associational literature, the quilt
provides the reader with 'snapshots' of history; each time
the reader looks at the quilt, different 'snapshots' are
considered and the reader's perspective necessarily
changes. Truth therefore becomes a wholly individual
concept.
The ever-changing versions of truth are represented in
the novel by the convergence of the novel's two communities
on the banks of the Shield River. It is here that the
concrete and abstract concepts of truth are brought
together to create flowing, multiplicitous versions that
are more analogous to First Nations traditions.


title: Growth and yield of teak (Tectona grandis Linn F.) plantations in Northern Ghana

subject:
Teak Yields Ghana
Teak Ghana Growth

abstract:
Teak (Tectona grandis Linn F.) is a popular exotic species in Ghana, widely
grown in industrial plantations and small scale community woodlots. In spite of its
importance, limited information exists on the growth and yield of this species.
Presented here are the results of a preliminary study aimed at assessing the
growth and yield potential and developing provisional yield models for the
management of teak in Northern Ghana. Data were collected from 100 temporary
sample plots from plantations in this region, ranging in ages from 3 to 40 years.
Local, standard and stand volume equations and tables were constructed from the
data. Additive above ground biomass and site index equations, and provisional
empirical yield models were also developed and presented. Site index curves were
used to classify teak plantations in the region into site classes I, II and III, in order
of decreasing productivity. The assessment of growth and yield revealed the
potential for growing teak to acceptable timber size on good sites. Yield functions,
indicate that teak can be grown on biologically optimum rotations of 31, 38 and 48
years on site classes I, II and III respectively. The diameter distribution was
modelled by the three-parameter Weibull function, using the maximum likelihood
and the percentile parameter estimators. The diameter distribution showed positive
skewness indicating there are more trees in smaller diameter classes. Initial
planting spacing of 2 by 2 m could be reduced to accommodate initial mortality and
to achieve optimum stocking levels in order to improve form and timber quality.

abstract:
This thesis critically examines generalizations offered in the fur trade literature regarding the impact of the amalgamation of the Northwest Company and Hudson's Bay Company upon Aboriginal trade partners. There are essentially two schools of thought. One asserts that Aboriginal trappers had become dependent upon European technology by the time of the 1821 amalgamation, and were forced to continue the trade exchange accepting the changes imposed by the Hudson's Bay Company during the monopoly period. The second perspective holds that Aboriginal trade partners were not dependent upon European technology and were adaptable, choosing to opt out of the trade exchange, focusing instead upon subsistence hunting and trapping to satisfy finite wants and needs. The focus of this research project is to evaluate these competing ideas about the amalgamation phase of the fur trade, using the records of Nipigon House Post dating between 1828 and 1838.
The fur trade is typically characterized by several predominant periods: the early fur trade, the competition phase, and finally the amalgamation phase. As each phase of the trade progressed, Aboriginal trade partners were affected in various ways. It is thought that in the post-amalgamation phase, there was a loss of Aboriginal bargaining power, and an extended time of hardship due to a widespread collapse in the viability of fur and food resources. This thesis examines how the Anishinabe community at Nipigon House Post was affected by the amalgamation. Data derived from the Journals of the Nipigon House are used to explore the Anishinabe community and their trade activities. Contrary to expectations deriving from the conventional fur trade literature that emphasize growing dependence upon the HBC, the Nipigon House data indicate adaptability to the monopoly period. This involved a limited demand for a narrow range of goods in keeping with the modest fur returns generated. Indeed many people focused heavily upon satisfying their subsistence needs, and sharply reduced their efforts at fur trapping. This contributed to a shift of the settlement system, with much more time spent along the lakeshore. These data suggest that the Lake Nipigon Anishinabe were not dependent upon European goods for survival. It can be concluded that reconsideration of generalizations about Aboriginal dependency during the monopoly phase of the fur trade is required.

abstract:
The present study examined how well gifted children in
regular classrooms were accepted by their classmates.
Fifty-four gifted and 681 normal IQ children in Grades
two through eight were given peer ratings by their
classmates and tested for self-esteem. Information was
gathered from the schools as to each subject's age, sex,
classroom, and for the gifted, IQ. It was found that
gifted children are more readily accepted in the domain
of academic pursuits than in other areas of peer
acceptance such as athletic and general social
activities. The trend is similar for self-esteem, which
is higher for the gifted sample only in the academic
area.


title: Management education of nurses-in-charge in Yukon

subject: Nurses Education Yukon

abstract:
Recruitment and retention of skilled, qualified nurses to northern regions of Canada is an
on-going problem. One of many contributing issues may be the lack of management education
afforded to the Nurses-In-Charge (NICs) in remote communities. If managers lack adequate
education, they cannot properly support the staff with whom they work; the environment of the
health centre therefore deteriorates, then retention and recruitment of nurses becomes difficult.
This study investigates the type and frequency of management education given to NICs
in the Yukon Territory. It also attempts to identify the type of education these NICs feel would
benefit them. Finally, a job satisfaction questionnaire attempts to determine how NICs feel about
their work relationships and their job in general.
Background Information:
For the past decade, Canada has been experiencing a nursing shortage (Maslove & Fooks,
2004, Office of Nursing Policy, 2005) which is expected to worsen during the next decade
(Canadian Nurses Association, 2002). When there is a nursing shortage, outpost nursing stations
and remote health centers suffer greatly, especially in First Nations communities; in 2001, there
was a reported vacancy rate of at least 40% on reserves, resulting in the closure of some nursing
stations for lack of staff (Fletcher, 2001). This kind of shortage results in poor continuity of care
to the detriment of patient well being (Minore et ah, 2005). Although nurse retention is a
complex issue, especially in northern Canada where little research has been done (MacLeod,
Kulig, Stewart & Pitblado, 2004), overwork, burnout, and lack of management support and
appreciation are some of the top reasons nurses cite for leaving northern areas (Tyler & Riggs,
2000).

abstract:
This thesis investigates the dietary preferences of northern goshawk populations
in second growth stands on Vancouver Island and the islands of the Johnstone Strait
region on the BC Mainland Coast. Prey abundance was inferred through the analysis of
pellets composed of regurgitated non-digested prey remains that were collected during
the annual survey monitoring program carried out by Mosaic Forest Management and
predecessor companies since 2012. The relative abundance of prey species was
compared across three Coastal Western Hemlock subzones (CWHvm1, CWHmm1,
CWHxm2) under the Biogeoclimatic Ecosystem Classification (BEC) system using the
Chi-square test. No significant correlations were found between prey species abundance
and BEC subzone (χ2 = 2.3, P = 0.32) in 2013 and (χ2 = 0.84, P = 0.66) in 2014. Trends
within the dataset indicate coastal northern goshawks on Vancouver Island and the BC
Mainland Coast show a general dietary propensity towards avian prey, which is
consistent with findings from other studies. The variation in prey abundance and species
diversity reported in this study is more likely a function of topography and forest
structure, season and region than it is to BEC subzones. Findings from this study
highlights how younger stands could be providing more suitable habitat than was
traditionally thought.

Discrete Ordinate (DO) model

abstract:
This study investigated one of the most important aspect of ultra-violet (UV) air disinfection modeling which is radiation modeling. Radiation modeling is a topic of interest in the domain of UV air disinfection research. Researchers in this field uses various types of radiation models to perform radiation modeling work including: Multiple Point Source Summation (MPSS),   Multiple Segment Source Summation (MSSS), Line Source Integration (LSI), View Factor model and Discrete Ordinate (DO) model; among the radiation models discussed, DO model is the only numerical iterative radiation model that can fully utilize the ever increasing power of computing,of today. Advantages of properly utilizing the DO model for radiation modeling include solving complex radiation problems in a full 3-dimensional space that provides ways to study fluence rate distribution easily. This work aims to properly utilize and validate the DO model by:
• demonstrating DO model’s consideration for basic optical principles (refraction,
reflection, shadowing effecting and partial absorption)
• studying fluence rate simulated values by comparing it with previously published
experimental work
• performing a 3-dimensional multi-lamp radiation experiment in conjunction with the
complex DO model radiation simulation case setup
The work performed shows that DO model is capable of considering basic optical principles (refraction, reflection, shadowing effecting and partial absorption) which are all integral to developing an accurate radiation model. Previously published use of the DO model in fluence rate studies concluded that DO model was inaccurate because some of the basic optical considerations could not be included in the solution; however, the findings of this work prove otherwise. A detailed description of utilizing DO model to account for these optical principles was outlined in this paper. With sufficient understanding of utilizing the DO model for UV lamp radiation cases, the scalability of using this newly described method to solve complex UV radiation cases was demonstrated. Additionally, DO model simulated results (with all basic optical considerations) are shown to match UV fluence rate values based on a published
actinometer radiation experiment to a good agreement.
This method was studied further by performing a complex multi lamp 3D radiation experiment and comparing the experimental readings to the DO model simulated result. The complexity of this UV radiation experiment is unprecedented as there are no published UV radiation lamp experimental work that could be found (during the time of writing). Unfortunately, the comparison between radiometer readings and simulated values did not show good agreement.  Although the DO model simulation results did not match the experimentally measured data completely, a lot of important optical considerations to include in a DO model simulation was explored. Findings from this study is significant to the application and utilization ofDO model in radiation modeling work for UV air disinfection.

Trees Ontario Acton Township Growth

abstract:
The objective of this study was to investigate the effect of different site
preparation methods on the establishment and growth of jack pine (Pinus banksiana Lamb.) on two different soil types. These sites were either site prepared using TTS Disc Trencher or by prescribed burning; sites were regenerated by seeding or by containerized planting. Data were collected in 7 year old jack pine plantations near Wawa, Ontario on
soils developed from glacialfluvial and moraine deposits. A total of 600 sample trees were randomly selected representing the soil types, the site preparation and the regeneration methods. The sampled trees were cut and their total volume determined. The data were
analysed as a split-plot design. The analysis of variance showed no significant difference between the seeded and containerized planted trees except with growth of basal area per hectare. There was also no significant difference in growth between soil type or between areas site prepared by the TTS Disc Trencher, prescribed burn or without site preparation.
Both the seeded and containerized planted areas met the jack pine growth standards set by the Ontario Ministry of Natural Resources. Although planted trees are larger than those obtained by seeding, the present net value for seeded stock is greater than that for planted stock. A complete factorial analysis of the data showed a significant difference in stems
per hectare and total tree volume for the soil types and site preparation methods. Further investigation of these differences may be important to the forest manager.

Congestion control theory

abstract: In this thesis, we analyze the performance of wireless LAN networks subject to random loss. In this regard, we use a congestion control technique that has been introduced in a previous study, titled TCP Congestion Control Enhancement for Random Loss (TCP CERL). TCP CERL is a sender-side modification of TCP Reno protocol. TCP CERL is an end-to-end technique that achieves high performance over wireless links and does not decrease the congestion window and slow start threshold if the random loss is detected. TCP CERL assumes a static threshold (A) equal to 0.55 which does not perform well when considering a heavy traffic load compared to new protocols. In this thesis, we propose a modified version of TCP CERL, called TCP CERL PLUS (TCP CERL+, in short). TCP CERL+ works similarly as TCP CERL, but its main idea is to use a dynamic threshold (A) in terms of Round-Trip Time (RTT) rather than static threshold. By doing so, we employ the average RTT and the minimum RTT measurements made over the connection to evaluate the queue length of the bottleneck link. In this thesis, we compare TCP CERL and TCP CERL+ with TCP New Jersey+, TCP mVeno, TCP Westwood+, TCP Cubic, TCP YeAH, and TCP NewReno by using Network Simulation NS-2. The results will show that CERL+ outperforms CERL when there are many users and Two-way transmission.

subject: Depression, Mental - Treatment

subject: Hopelessness depression

subject: Adaptive inferential feedback (AFI)

abstract:
The theory of hopelessness depression (Abramson, Metalsky, & Alloy, 1989)
states that the presence of the psychological state of hopelessness is a sufficient cause for the development of a specific subtype of depression called Hopelessness Depression (HD). The state of hopelessness, in turn, develops through a combination of several contributory causes that include the lack of general social support and a specific type of social support called adaptive inferential feedback (AIF). AIF refers to the feedback from others to an individual that promotes optimistic, rather than pessimistic, inferences about the causes, consequences and meaning of negative events. The objective of the present study was to determine whether participants taught to give themselves AIF (i.e., given direct instruction on how to change pessimistic attributions to optimistic ones for actual negative life events) would experience larger changes in cognitive style, hopelessness, HD symptoms, but not non-HD depressive symptoms, relative to participants who did not receive this instruction. The study further sought to examine the relationship between maladaptive inferential feedback (MIF) from one's environment and changes in these variables. A group of undergraduate students with a pessimistic attributional style was randomly assigned to either a Treatment group or a no-treatment Control group. The Treatment group underwent an optimism training workshop and for 28 days thereafter, engaged in disputation techniques in response to actual negative events in their lives. Pre- and post-assessments of the cognitive style, hopelessness, and HD- and non-HD depressive symptoms of the two groups were carried out. Results indicate that AIF from the workshop predicted change in HD- and non-HD depressive symptoms and that this relationship was mediated by a change in cognitive style.  Supplementary analyses indicated that practicing the disputation skills for one week predicted change in hopelessness, HD- and non-HD depressive symptoms. Implications for the role of AIF in alleviating hopelessness and depression as well as implications for the validity of the HD theory overall are discussed.
