abstract:
The Beardmore-Geraldton greenstone belt is located along the boundary between the Wabigoon and Quetico subprovinces in the Superior province of the Canadian Shield. Historical gold mines and current gold exploration camps are located throughout the Beardmore-Geraldton greenstone belt and adjacent Wabigoon subprovince in moderately to steeply dipping ductile to brittle-ductile shear zones in many types of lithologies, with various metamorphic grades, and alteration styles. The shear zones typically strike east-west along the boundary of the Beardmore-Geraldton greenstone belt with the Wabigoon subprovince to the north as well as along the boundary with the Quetico subprovince to the south.
Field mapping and petrography, including microstructural analysis, were used to characterize the gold mineralization and investigate the control on gold mineralization in the Elmhirst, Castlewood, Pagwachuan, and Milestone properties in Greenstone, Ontario. Two property-scale and seven trench-scale maps were produced from field mapping and one hundred twenty-three transmitted and reflected light thin sections were prepared from samples collected from these properties. Lithology, structure, microstructure, metamorphic grade, alteration, and subprovince were considered as possible controlling factors on gold mineralization.
In the study area gold mineralization is hosted in relatively competent lithologies including schistose to mylonitic metamorphosed granodiorite, syenite, and pegmatite; chlorite-albite schist, schistose amphibolite, and garnet-hornblende-biotite schist. The regional-scale structures that host gold mineralization are ductile to brittle-ductile shear zones that have a penetrative, schistose foliation and rarely a mylonitic fabric. The property-scale structures that host gold mineralization are folded, mylonitized, and boudinaged quartz veins; shear-related early, late, and complex folds; folded fault breccia, and pressure shadows of rigid minerals within schistose to mylonitic fabric. Gold mineralization is located in areas of micro-folds, micro-boudins, micro-fault breccia, undulatory extinction, and grain size reduction along irregular grain boundaries, subgrain boundaries, folded healed fractures, and in pressure shadows within areas of strain heterogeneity. Gold mineralization is located in both areas of greenschist facies and amphibolite facies metamorphism in the study area. The styles of alteration also vary within the study area with sericite, hematite, ankerite, calcite, and unaltered samples all hosting gold mineralization. Both the Wabigoon and Quetico subprovinces host gold mineralization in similar structures and microstructures as the Beardmore-Geraldton greenstone belt although it is within different lithologies, metamorphic grades, and alteration styles.
Similar structure and microstructure are always present in areas of gold mineralization in the study area while lithology, alteration, metamorphic grade, and subprovince vary. Gold mineralization within stable prograde and retrograde metamorphic minerals indicates that gold mineralization was synchronous with ductile to brittle-ductile deformation and metamorphism. Further gold exploration in the study area should focus on structure and microstructure as indicators for gold mineralization.


title: Test of personality and complementarity in dyadic interactions using sequential analyses

subject:
Social interaction
Interpersonal relations

abstract:
Can patterns or redundancies be identified in the
sequences of behaviors that are exchanged between
individuals in social interactions? The present study
directly examined the most controversial form of
complementarity: whether dominant behaviors are
followed by submissive behaviors, and whether
submissive behaviors are followed by dominant
behaviors. We were specifically concerned with recent
claims that complementarity on the dominant -
submissive axis does not exist, and that dominant -
submissive behavior is instead the result of
personality tendencies. Clear evidence was found for
complementarity in relational control behaviors
utilizing appropriate aggregated and sequential
analyses. However, there was also an unexpected
tendency for dominance to evoke further dominant
behaviors. Individual difference tendencies were
correlated with relational control behaviors, but not
as strongly or consistently as predicted.

abstract:
The chronic pain experience is a multifaceted phenomenon
involving sensory, cognitive, affective, motivational and behavioral
dimensions. There has been no single consistently successful method of
pain control and multiple treatment approaches are frequently utilized by
the chronic pain sufferer. The treatment approach investigated in this
experiment used a relaxation technique coupled with visualization.
Thirty-two chronic pain subjects with various diagnoses were divided into
four groups using a quasi-random design. Two groups received training
in a relaxation technique for eight weeks, and two groups started with
relaxation and then were also given a visualization procedure for the
final four weeks. Assessments using the McGill Pain Questionnaire, the
Multidimensional Health Locus of Control, the Profile of Mood States,
and the West Haven-Yale Multidimensional Pain Inventory were done
before treatment, at the mid-point, and at the end of treatment.
The results showed no consistent differences between treatment
groups and failed to indicate any clear-cut advantages for either
relaxation or visualization in controlling chronic pain. There was no
consistent reduction in pain or pain behaviors over the course of the
experiment regardless of situation.

abstract: Plots were done in various locations to determine the effect of the jack pine budworm on fire frequency to the insect outbreaks on jack pine budworm infected sites. This information can be useful in determining resulting ignition risk in infected stands as well as fire behaviour if fires s, intensity and severity in Northwestern Ontario. The infected plots were measured near Bak Lake attack base in the Red Lake district where stands have been heavily infected with budworm and defoliated. The control plots of healthy mature jack pine were measured in stands north of Ignace. More mortality of jack pine trees was recorded in infected sites however fuels, including downed-woody debris and organic forest floor layers, were generally still greater on mature sites of jack pine. This may be due to the timing of disturbances, like wildfire, on mature sites compared pread.

Slash (Logging) Ghana, Western
Logging residue
Harvesting efficiencies

abstract:
In the face of increasing demand for industrial wood and the serious reduction of the
forest resource base in Ghana, logging is reported to be wasteful. However, the level of
wastage or residue generation has not been well quantified and described in regard to its
potential uses and/or effects on the resource base. Data were collected from 100
sample trees during normal commercial harvesting operations in five logging sites within
four forest districts in the Western Region of Ghana. The data were analysed in order to
assess the extent of logging residue. On average, 79 percent of the total bole volume
and 68 percent of the measured above-ground total tree volume was extracted as logs.
Thus, 32 percent of the measured above-ground total tree volume was left in the forest
as residue. Branch wood was the highest average proportion of logging residue followed
by crown-end offcuts, butt-end offcuts and stump wood. Logging residue may be
attributed to a variety of causes including natural defects, and human errors and/or
inefficiencies of machine operators. This study indicated significant differences in
harvesting efficiencies among timber species and among logging companies.
Efficiencies were highest in the two large-scale companies followed by the mediumscale
and the small-scale companies. These differences emanated from the level of
integration of the companies, equipment and machinery available, the competence of
the workforce, terrain conditions, bole shape and form, bole length, occurrence and
extent of natural defects, and rarity and commercial value of the species.
The study further showed that for a combination of various species, 56 sample trees will
be required at an allowable error of ±10 percent and a confidence level of 95 percent in
order to estimate the proportions of the various identified logging residue (or tree
sections). Provisional biomass models were developed for predicting the measured
above-ground total tree volume and thereby the measured above-ground total residue
volume. Also, provisional local and standard volume equations were developed for
forest resource management. Generally, the species-specific models were more precise
than the generalised equations.
In order to increase recovery and utilization of harvested trees, potential types of forest
products which might be converted from logging residue were identified. These products
include small-size solid products (e.g., scantlings, strips, squares, narrows, shorts,
parquet and strip floorings, broomsticks, profile boards, mirror and picture frames), chips
for wood-based panel products, pulp and paper, charcoal, fuelwood and other potential
commercial uses.

abstract: Study location : Emo, Northwestern Ontario.

abstract:
The need for community-based, client-centred end-of-life care is particularly evident in rural
areas in order to allow people to die amongst their family and friends. However, resources are
limited and there is often a lack of coordination and communication between the agencies
responsible for providing rural community care. In 2008 the North West Community Care
Access Centre (CCAC) received funding from the Local Health Integration Network (LHIN) to
create a resource, specifically a “toolkit”, that would guide communities in the development of
local palliative and end-of- life care programs and facilitate seamless, integrated care. The
outcome of this funding was a document called “Building A Community End of Life Care
Program: A Toolkit for Action”, which is referred to here as the Toolkit (see Appendix A).
With the Toolkit now being disseminated throughout the region, this project aims to describe
how it is being used by certain communities in Northwestern Ontario and how it might be
improved to optimize its value for program planning and development. This evaluation is being
supported by the Interdisciplinary Capacity Enhancement (ICE) program of research titled
“Timely Access and Seamless Transitions in Rural Palliative/End-of-Life Care”. This five year
program of research is being funded by the Canadian Institutes of Health Research (CIHR) and
involves a team of researchers from across Canada working on ten different projects.
Specifically, this evaluation is being supported by ICE Project 9, “Refinement and testing of a
conceptual model for developing and delivering rural palliative care programs”, which is being
led by Dr. Mary Lou Kelley of Lakehead University and Dr. Allison Williams of McMaster
University.

abstract: Hydrogen sulfide (H2 S) has emerged as a novel and important gasotransmitter for the cardiovascular system, where it is generated mainly by cystathionine γ-lyase (CSE). Abnormal metabolism and functions of the H2 S/CSE pathway have been linked to cardiovascular diseases including hypertension and atherosclerosis. Hypoxic stress is a hallmark of these pathophysiological processes. Here we characterized the response of vascular smooth muscle cells (SMCs) derived from CSE-knockout (KO) mice to hypoxic stress. Under basal conditions we found that KO cells exhibited increased metabolic activity (+27 %), ROS levels (+127 %) and mitochondrial membrane potential (Ψ m ) (+62 %) than their wild-type (WT) counterparts. These data suggest an impaired ability of KO cells to regulate redox levels and/or increased by-production of ROS resulting from deficient H2 S-mediated regulation of mitochondrial activity in the KO cells. Hypoxic insult (12 h, 1% O2 ) caused a decrease (-61 %) in KO cell metabolism and a dramatic increase in apoptosis of KO versus WT cells (+85 % versus +23 %), indicating susceptibility of KO SMCs to hypoxic stress. We also found hypoxia-induced increases in the activity of antioxidant enzyme, superoxide dismutase, in both WT and KO cells, but markedly increased (+75 %) ROS levels in hypoxic KO cells, revealing a profound redox imbalance therein. Additionally, we noted: (i) a large Ψ m increase (+118 %) in hypoxic KO versus WT cells; (ii) that KO SMCs featured altered inflammatory mediator expression both under basal and hypoxic conditions; (iii) blunted hypoxia inducible factor-α expression in the CSE-deficient cells. Taken together, these data demonstrate that H 2 S/CSE pathway is essential for SMC survival under hypoxic conditions, and suggest that endogenous H2 S modulates redox and inflammatory status and mitochondrial activity, deficiency of which may cause the observed vulnerability of KO cells to hypoxia. In another series of experiments, we examined the effect of the hypoxia mimetic, cobalt chloride (CoCl2 ), as well as hypoxia-reoxygenation (H-R) stress, on HL-1 murine cardiomyocytes. We demonstrated that both CoCl 2 and H-R caused decreased cardiomyocyte viability (-28 % and -37 %, respectively), and that CSE expression was concomitantly increased (+79 % and +94 %, respectively). D-propargylglycine-mediated inhibition of CSE was found to exacerbate CoCl2 -induced decreases in cardiomyocyte viability. Taken together, these data indicate that H2 S/CSE pathway is upregulated in response to both simulated hypoxia and H-R stress, and that endogenous H2 S/CSE pathway contributes to cardioprotection against CoCl2 -induced stress. These findings suggest an important role for endogenous H2 S/CSE pathway in cytoprotection against hypoxia in murine SMCs, as well as against simulated hypoxia and H-R stress in HL-1 murine cardiomyocytes. Moreover, they are consistent with the concept of meaningful involvement of H2 S/CSE pathway in the hypoxia stress response and the recent suggestion of H2 S/HIF-1 interaction.


title: Predicting moral behaviour in sport: individual and interactive relationships involving motivational climate, gender, and perfectionism

subject: Environmental factors that influence moral behaviour

subject: Perfectionism and moral behaviour

abstract:
A large proportion of Canadian youth aged 15 to 19 – approximately 60 percent – participate in organized sport (Canadian Fitness & Lifestyle Research Institute, 2015). Given this significant number, popular media portrayals of the behaviour of athletes have the potential to shape the behaviour of youth athletes (Bush, Martin, & Bush, 2004). Appropriate behaviour is determined in part by the internalized morals and values one has adopted (Bandura, 1991). With the exception of family, sports provide one of the most influential social environments with which an individual may be involved (Bruner, Boardley, & Côté, 2014). Throughout the course of a competition, incidents may occur that result in athletes choosing to behave in a manner that results in positive outcomes for others, or choosing to behave in a way that results in negative outcomes for others. For example, Sarah Tucholsky was a senior outfielder for the University of Western Oregon’s softball team when she hit her first career home run (CBS News, 2008). In her excitement, she missed first base, and when she turned back to tag the base, she injured her knee. Unable to run, the opposing team’s first base woman and their shortstop asked permission and carried Tucholsky around the bases resulting in a three-run victory for Tucholsky’s team. In contrast, Elizabeth Lambert was a defender with the University of New Mexico’s women’s soccer team when she became infamous following a game in which she exhibited several aggressive and decidedly unsportspersonlike behaviours. Throughout the game she punched, tripped, tackled, and finally pulled an opposing player to the ground by her ponytail (Clayton, 2010), behaviours that eventually earned her a yellow card (a penalty in soccer).
Incidents of positive and negative behaviour in sport, as exemplified by the experiences of Sarah Tucholsky and Elizabeth Lambert described earlier, have received considerable attention from both the public and the media highlighting the value of investigating moral behaviour in sport (Perry, Clough, Crust, Nabb, & Nicholls, 2015). How athletes choose between positive and negative behaviour may be influenced by many factors, including the influence of their personality and the influence of the environment. An even greater understanding of moral behaviour in sport may be obtained by simultaneously considering the interaction between personality and environmental factors (Bandura, 1991; Hodge & Lonsdale, 2011; Kavussanu, 2012). The present study was conducted in line with this contention.


title: The economic value of recovering the town of Oakville's urban forest after the impacts of the emerald ash borer

subject:

Emerald ash borer

abstract: The Town of Oakville is responsible for maintaining some 2,016,500 city trees planted within boulevards on the city’s streets (UFORE 2016). Prior to the emerald ash borer, ash trees represented the top 5 most trees planted in Oakville’s city owned streets and parks (UFORE 2016). Additionally, ash make up approximately 3.6% of Oakville’s urban forest. The occupation of urban forestry provides benefits which include the care and maintenance of street trees within cities and metro areas. Benefits to residents of these areas include improved air quality, lower urban air temperatures, stormwater management, added property values and a reduction of municipal property costs (Zabret 2015). Within this study, white and green ash diameter at breast height (dbh) were categorized into different dbh classes and averaged. The total benefits were attained (or provided) by the National Street Tree Benefit Calculator and combined to get a total cumulative loss of $1,984,226.46 CAD if these trees were to die off. However, errors in this study were concluded that the economic cost of a dollar were to be in current value in 2019. Additionally, there was another error that the town of Oakville did not document why the ash tree was removed. Further research will be required and needed increase comprehension of the results of this study. However, the Town of Oakville is implementing strategic management plans in order to still ensure a diverse and well beneficial urban forest.

abstract: Web handling systems are widely used in industries such as pulp and paper, printing press, and steel milling. Tension variations in web materials are very common in operation and tension control is critical to the quality control of the related manufacturing facilities. Speed variations or changes will cause fluctuations in web tension; as a result, speed control is another important issue in web handling systems to prevent machinery performance degradation and to maintain desired productivity. The web system control problem is investigated comprehensively in this research on both intermediate zone and unwinding-winding process.

Sedimentology

abstract:
A geoarchaeological investigation was north of Highway 11/17, 34km east
of Thunder Bay, Ontario. Five archaeological sites (Mackenzie 1, Mackenzie 2,
RLF, Woodpecker 1, and Woodpecker 2) and seven additional sediment
exposures were examined for stratigraphic analysis to accompany the
archaeological excavations. River-mouth sediments at 268m asl and a series of
deltas indicate that the study area was subaqueous while placement of the
Superior lobe prevented drainage to the Superior basin. This elevation is
consistent with Lake Beaver Bay, an ice-contact lake that received glacial
meltwater from the north (the Hudson Bay lobe) as well as the south (the
Superior lobe). This is demonstrated by southward and northward prograding
deltaic sequences within the study area.
As the Superior lobe made its final retreat, Lake Beaver Bay dissipated
into the Superior basin marking the beginning of the Minong phase, likely around
9,900 14C yrs BP. Additional sequences representing river-mouth, beach
shoreface, and deltaic depositional environments indicate that a series of
shorelines within the study area represent subsequent Minong lake levels. The
highest, and likely oldest of these strandlines is an erosional feature at 256m asl,
consistent with wave-cut terraces previously identified in the Thunder Bay region.
Relative lake level drops occurred, likely due to a combination of gradual
erosion of the Nadoway Point sill and isostatic rebound of the recently
deglaciated land. Beach and river-mouth sequences representing subsequent
shorelines are located at 249m, 243m, and 240m asl. Artifacts on each of these
beach terraces suggest they were occupied by Paleoindian groups.

Potatoes Dormancy
Potatoes Genetics

abstract:
The growth and harvest of potato tubers for agricultural purposes is important both in Canada and worldwide, and the agronomic importance of this crop is steadily growing. A major issue affecting the storage and transport of raw potatoes is the precocious sprouting of tuber shoot apical meristems (SAMs), which is a result of tuber emergence from endodormancy. Current methods of potato storage that prolong endodormancy require either large cold storage facilities, or the use of growth suppressing chemicals. In this study, tuber SAM growth and the molecular mechanisms underlying endodormancy emergence were investigated to better understand the physiological processes involved. During emergence, SAM length increased and was paralleled by increased DNA synthesis as early as 7 weeks post-harvest, suggesting endodormancy release before or at this time. The genes WUS and STM, which are involved with meristem maintenance and growth, were expressed as early as 7 weeks post-harvest. By 11 weeks post-harvest, WUS was expressed at significantly higher levels (~5 fold) than in endodormant tuber meristems. PKL and CUCl, genes thought to be involved in the activation of WUS and STM, increased in expression at 11 weeks, then
decreased to significantly lower levels at 15 weeks. Expression of other dormancy enforcing genes such as ABI5 and DHN also significantly decreased during emergence. Suppressive subtractive hybridization identified other genes that were down-regulated in non-dormant tissues. These included BPSl, thought to be involved with synthesis of a
mobile signal, whose mRNA levels were significantly lower at 15 and 19 weeks, and RCEl, a member of the SCF [superscript TIR1] complex involved with auxin regulated protein degradation, which had significantly lower mRNA levels after 19 weeks. Additionally, the stress tolerance gene DREB2a showed a slight increase in expression (-20%) at 11 weeks post-harvest but then decreased, and at 19 weeks post-harvest it was significantly lower (-40%). Expression of the cell cycle dependent gene cyc07 and a WD-Repeat gene were characterized as well. The molecular mechanisms investigated contribute to the understanding of tuber endodormancy, which may lead to better cultivation and storage
practices.

abstract:
This qualitative study describes the relationship between young adolescent readers’
comprehension of environmentally-themed literary texts and the representation and
reinterpretation of those texts through drama. The participants in this study were four members
of one response group from a Grade 6 class engaged in a five week, text-based unit on humane
and environmental education.
Three themes emerged from the analysis of the data; curriculum design and
implementation, comprehension, and metacognitive awareness. Data analysis was facilitated by
Protherough’s (1983) framework for response, Rubin’s (1990) levels of comprehension, and
Eisner’s (2003) dimensions of curriculum.
Various factors influenced student comprehension during the study. These included;
i) elements of design such as the conceptual framework of the unit, the conceptual linking of
texts, the guided practice of using strategies to promote comprehension and metacognitive
awareness, the use of drama to mediate comprehension, and sustained engagement with related
text sets; (ii) planned and spontaneous teacher interventions to scaffold learning experiences and
facilitate critical literacy; and, (iii) opportunities for shared and private engagement, response
and reflection through oral, written, and dramatic symbolic systems.
The detailed design and implementation of the unit on humane and environmental
education illuminates the processes undertaken by educators involved in curriculum design,
development and implementation. It also provides a comprehensive model for the teaching of
humane and environmental education within the conceptual framework of a response-based
language arts unit.


title: Assimilation of basic xenoliths within centre 3 syenites of the Coldwell Alkaline Complex, Ontario

subject: Geology Ontario Coldwell Alkaline Complex

subject: Syenite Ontario Coldwell Alkaline Complex

abstract:
This thesis describes the occurence, mineralogy and assimilation of
basic Kenoliths hosted by Centre 3 syenites. Field work ‘was earned out in
two locations, one in the vicinity of Neys/Ashburton and the other a large
megaxenolith hosted by Centre 1 syenites in the vicinity of Wolf Camp Lake.
Least altered Menoliths consist of plagioclase, pyreo^ene. arnphibole,
biotite, apatite and opaque phases. 'With increasing assimilation this
changes to a combination of plagioclase, arnphibole, biotite, apatite, opaque
phases, alkali feldspar, calcite, fluorite, sphene, zircon, REE phases and
quartz.
Plagioclase is replaced by alkali feldspar in the form of oorphyroblasts
and crystals in the groundmass. Plagioclase is also decalcified to more
albitic compositions along with recrystallization. Arnphibole compositions
extend over the same range of arnphibole compositions in the host
ferro-edenite syenite. The general effect of xenolith assimilation is the
equilibrium of a xenolith’s mineral assemblage to that of the host syenite.
Assimilation processes seen at Wolf Camp Lake are similiar to those seen at Neys/Ashburton.
Bulk rock data along with mineralogical compositional variation in
clinopyroxenes, suggest a tholeiitic basalt parentage for x.enoliths in both
areas. Cr and Ni contents indicate an evolved nature to the parent volcanics.
Data also suggest the possible existence of a second undersaturated type of
volcanic xenolith present at Neys/Ashburton. Parental basalts are
postulated to be coeval volcanics related to the formation of the Coldwell
Complex.
Modelling by mass balance mixing calculations of contamination of host
syenites indicates that contaminated ferro-edenite syenites are the result
of direct assimilation of volcanic xenoliths by ferro-edenite syenite. Quartz
syenites are found to be unsuitable parents to contaminated ferro-edenite
syenites.

Love throughout the lifespan

abstract: This study examines how passionate, companionate, and compassionate love are experienced throughout the temporal course of a romantic relationship and throughout the lifespan. It was hypothesized that passionate love would be negatively correlated with relationship length, and companionate and compassionate love would be positively correlated with relationship length. Additionally, it was hypothesized that age would not affect individuals’ levels of the three types of love. Two hundred and seventy-three individuals, ranging in age from 18 to 74 years old, completed self-report measures assessing their levels of passionate, companionate, and compassionate love. Data were analyzed using multiple regression and mixed level modelling. Results from the regression analyses show that no effect of relationship length was found for levels of passionate or compassionate love, but a significant positive correlation was found between relationship length and companionate love. No effect was found for age on the three types of love, except for an interaction effect between relationship length and age for companionate love, in which age moderated the relationship between relationship length and companionate love. Mixed modeling results suggest that over the three love scales combined, love increases with relationship length. Additionally, a significant triple interaction between love, relationship length, and age suggests that with increases in age and length of relationships, the passionate and compassionate scales showed higher levels of love than the companionate scale. Additional variables including gender, relationship orientation, living arrangements, and marital status were also explored. This study offers insight into the temporal course of the three aforementioned types of love in romantic relationships, and suggests that individuals’ ages do not affect levels of love.


title: Results on perfect graphs

subject:
Graph theory
Perfect graphs

abstract:
The chromatic number of a graph G is the least number of colours that can be assigned
to the vertices of G such that two adjacent vertices are assigned different colours. The
clique number of a graph G is the size of the largest clique that is an induced subgraph
of G. The notion of perfect graphs was first introduced by Claude Berge in 1960. He
defined a graph G to be perfect if the chromatic number of H is equal to the clique
number of H for every induced subgraph H C G. He also conjectured that perfect
graphs are exactly the class of graphs with no induced odd hole (a chordless odd cycle
of greater than or equal to five vertices) or no induced complement of an odd hole, an
odd anti-hole. This conjecture, that still remains an open problem, is better known as the
Strong Perfect Graph Conjecture (or SPGC). An equivalent statement to SPGC is that
minimal imperfect graphs are odd holes and odd anti-holes.
Fonlupt conjectured that all minimal imperfect graphs with a minimal cutset that
is the union of more than one disjoint clique, must be an odd hole. In this thesis we
prove that any hole-free graph G with a minimal cutset C that is the union of vertexdisjoint
cliques must have a clique in each component o f G — C that sees all of C. We
further prove that minimal imperfect graphs with a minimal cutset that is the union of
two disjoint cliques have a hole.
Since the introduction of perfectly orderable graphs by Chvdtal in 1984, many classes
of perfectly orderable graphs and their recognition algorithms have been identified. Perfectly
ordered graphs are those graphs G such that for each induced ordered subgraph
H of G, the greedy (or, sequential) colouring algorithm produces an optimal colouring
of H. Hohng and Reed previously studied six natural subclasses of perfecdy orderable
graphs that are defined by the orientations of the P4 ’s. Four of the six classes can be
recognized in polynomial time. The recognition problem for the fifth class has been
proven to be NP-complete. In this thesis, we discuss the problem o f recognition for the sixth class, known as one-in-one-out graphs. Also, we consider pyramid-free graphs with
the same orientation as one-in-one-out graphs and prove that this class of graphs cannot
contain a directed 3-cycle of more than one equivalence class.

Structural geology

Natural remanent magnetization

abstract:
The thesis area is located 120 km west of the City of Thunder
Bay, Ontario, straddling the contact of the Quetico and Wawa
subprovinces of the Archean Superior Province.
Metasedimentary rocks of the Quetico Subprovince with basic and
granitic intrusions occupy the northwestern portion of the study
area and are in contact to the southeast with metamorphosed mafic
and felsic metavolcanic rocks of the Wawa Subprovince.
Tectonic compression has shortened the metasedimentary rock
layers a minimum of 80%. Bedding dips steeply to the northwest and
a later cleavage, developed by transpression, is sub-parallel to
bedding. Graded beds young predominantly to the northwest. Some
graded beds young to the southeast and may represent pre-cleavage
folding. No large-scale folds are present. Metamorphic grade
increases northwest from greenschist to amphibolite facies over a
distance of about 10 km.
Magnetite is the predominant magnetic component of the Moss
Lake stock; hematite is present in trace amounts. Magnetic
susceptibility of the stock is high ( 12,000 X10-6 SI), making the
intrusion amenable to anisotropy of magnetic susceptibility (AMS)
work.
AMS study of the Moss Lake stock shows that individual
directions of maximum susceptibility have been reoriented, in most
cases sub-parallel to the local planar fabric strike of the Quetico
Subprovince. Magnetic fabric parameters show that the rock magnetic
fabric of the intrusion is deformed. Vestiges of original magmatic
fabric are evidenced by prolate (constricted) magnetic fabric
associated with the central long axis of the stock but magnetic
fabric parameters confirm that the intrusion margin is more
deformed than the interior. The predominant oblate (flattened)
magnetic fabric of the Moss Lake stock is the product of northwestsoutheast
tectonic compression.
Alternating field and thermal demagnetization of oriented rock
specimens confirm that the Moss Lake stock is deformed by tectonic
compression. Separation of magnetite and hematite magnetic
contributions, by blocking temperature, reveals that primary
natural remanent magnetization (NRM) orientations from hematite are
parallel to the local planar fabric strike of the Quetico
Subprovince. Minor preservation of primary magmatic fabric is
indicated by the mean principal component analysis (PCA)
orientation for magnetite which corresponds closely in trend to the
mean ~ e orientation for the region, obtained by previous
investigators. Original Moss Lake stock magnetic fabric is
overprinted by compression and shearing.
Comparison of magnetic studies (AMS and NRM) of the Moss Lake
stock to structural data of country rocks argues in favor of a
common tectonic control.

The purpose of this study was to examine the interaction effects of athletic
participation, gender, and academic stream with self-esteem, academic achievement, and
educational aspiration. The sample (n=341) was drawn from potential graduates from
three high schools in Thunder Bay, Ontario. Athletic participation was collected from
self-reported student data in the areas of varsity (school) and recreational (both within
and outside of school) sports. Global self-esteem was measured with the Coopersmith
SEI Inventory (1981). Quantitative results were analysed using MANOVA. Results
showed that male athletic participants had higher self-esteem scores, whereas females
had higher grade point averages (a = .01). Self-esteem for general level students was
lower than that of advanced level students, particularly in females. Academic
achievement as measured by grade point average had no relationship with athletic
participation but educational aspirations varied positively with academic stream.

abstract:
Once native to Ontario, eastern elk (Cervus elaphus canadensis) occupied much
of the deciduous forest biome of eastern North America. However, increasing human
settlement, as well as demands for meat and agricultural land resulted in their extirpation
during the late 1800s and early 1900s. In 1995 the government of the province of Ontario announced an elk restoration initiative, and from 2000 to 2001 a total of 108 western elk (Cervus elaphus manitobensis) were translocated from Elk Island National Park (EINP), Alberta, to northwestern Ontario. Subsequent monitoring of the elk provided unique opportunities to measure their success in a boeal landscape, assess reintroduction methodologies, and gain knowledge required for future management strategies. The specific objectives of this study were to examine the spatial behaviour, habitat relationships, and population characteristics of the recently reintroduce elk. As well, data relating to the transmission of two cervid parasites, Fascioloides magma and Parelaphostrongylus tenuis, on Ontario range were collected.
Two years after the initial reintroduction, 70% of the elk were still within 20 km
of the release site. The remaining 30% (10 adult males and 12 adult females)
permanently dispersed to the south, approximately 90 km from the release site. Mean
maximum distance moved following release was farthest for elk translocated as adult
males (68 ± 15 km ), follow ed by adult females (37 + 6 km ), female calves (8 + 1 km ) and
male calves (6 km + 0.7 km).

Food security service providers

abstract:
In Canada, staggering rates of household food insecurity are emblematic of broader issues, such
as systemic discrimination, poverty, and a global, capitalist food system. The means to address
food insecurity are contested within the nation. For example, community-based programs (e.g.,
food banks), continue to be common, despite concerns that they may induce shame and guilt in
those who access them and fail to address the root causes of the issue. Despite this, some authors
have argued that such spaces may offer transformational potential to bring community members
together in-common across class divides in the meantime. Limited research exists on the
experiences of frontline food security service providers, and more specifically on how they
conceptualize their work. In this thesis, semi-structured interviews and photovoice were used,
following an interpretive phenomenological design. Specifically, I sought to explore how
frontline food security service providers in Thunder Bay experienced their work, and the
interactions between their intrapsychic factors and processes, organizational practices and their
visions for the future of their work. Three superordinate themes emerged, demonstrating that
participants were thinking about broad issues (e.g., poverty, racism), found tensions in the role of
lived experience (e.g., as both a motivation to come to the work and a risk factor for burnout),
and saw their role as care work underscored by shared values. The findings also highlight the
importance of an interactional approach, exploring how an individual's early life experiences,
values and sense of self, alongside organizational factors and others in the field, worked in
concert to create their experience. While this work does not intend to make broad claims about
the experience of all food security service providers, it highlights some of the voices in Thunder
Bay, Ontario, and the opportunities they have in transforming food access to be more just and
equitable for all.

abstract:
This study explores teacher candidates’ and course instructors’ experiences and perspectives of a mandatory Aboriginal Education course at Lakehead University’s teacher education program. The study utilizes a mixed methods approach that combined a qualitative study that integrates tenets of arts-informed inquiry with a quantitative survey. The purpose of this study was to examine how self-reflective practices are used in helping teacher candidates increase awareness of their own beliefs, attitudes, and assumptions about Indigenous histories, cultures, and perspectives in a mandatory Aboriginal Education course. It also explores what five course instructors describe as effective instructional strategies or practices, and the impact of a mandatory course on teacher candidates’ knowledge of, interest in, and attitudes towards, Indigenous Education.
Data were collected from multiple methods and procedures (i.e., 5-point Likert scale survey, open-ended questionnaire, one-on-one interviews, student assignments, and reflective journal), and multiple sources (i.e., teacher candidates, course instructors, and author’s participant as observer role). Findings are presented in three research articles prepared for academic journals. Following the research articles is a discussion of data not addressed in the articles.
Article 1 discusses the purpose and impact of self-reflective practices from teacher candidates’ perspectives, including as a method for self-evaluation, a method for creating a personal connection to course theory, or a method for developing a culturally inclusive pedagogy. In Article 2, five course instructors describe instructional strategies and assignments that they perceived to be most effective for the mandatory Aboriginal Education course in Lakehead University’s teacher education program. Although each instructor had their own particular approach to the course, themes of story, land, art, and reflection emerged from their examples and are discussed. Article 3 explores teacher candidates’ knowledge of, interest in, and attitudes towards the mandatory Aboriginal Education course from teacher candidates’ and course instructors’ perspectives. While many teacher candidates indicate that they felt knowledgeable by the end of the course, course instructors caution that the knowledge and skills taught in the course are limited with more needed as teachers enter their professional career.
The dissertation concludes with recommendations about reflective practices in an Indigenous Education course, the integration of Indigenous Education courses in initial teacher education and professional development, and future research possibilities that may extend the findings that emerged from the current study.

subject:
Lake sturgeon

abstract: Social network analysis is the study of individuals or units and the relationship between them at a given time. It allows insight about evolution, maintenance of social relationships, and behavioural characteristics. These networks can help measure and describe the overall structure and stability or vulnerability of a group. Such measures of vulnerability are especially important for Lake Sturgeon (Acipenser fulvesens), due to their threatened status across Canada. This study had three objectives: (1) to find groups of Lake Sturgeon residing in the Namakan River, Fort Frances District, Ontario that might consistently migrate upstream at the same time, (2) to find groups of Lake Sturgeon that consistently arrive at the same spawning reaches each year, and (3) to determine if groups of Lake Sturgeon residing in the Namakan Reservoir consistently interact with one another. Telemetry data from the Namakan River and Reservoir were used to determine if social networks were forming over a period of five years. No social groups were found in the Namakan River during this time, but there was evidence of their formation in the Namakan Reservoir. This information can aid in developing management plans for Lake Sturgeon in the Namakan River and Reservoir.


title: Health professionals and climate change communication: An exploratory study in Northern Ontario

subject: Health and climate change

subject: Climate change communication (Health professionals)

subject: Climate and health education

subject: Climate change mitigation

abstract:
Health professionals are recognizing and experiencing the impacts of climate change in their
work and understand the need to communicate this information to the people and populations
they serve. Improved climate change communication, utilizing health professionals’ trusted
position in society, has been highlighted as a means to effectively create engagement and
stimulate support for climate action. While effective methods of communicating climate change
have been identified, there is a dearth of literature demonstrating how health professionals are
communicating climate change in their work. In recognition of this gap in research, this study
examined how health professionals, who identify as climate change leaders, perceive and
communicate climate impacts and action in Northern Ontario. Key-informant interviews (n=19)
were conducted with health professionals engaged as climate change leaders in Northern
Ontario. The findings from this study revealed that a concerned and passionate subset of
Northern Ontario health professionals exists, who understand and recognize the serious health
implications presented by climate change. These health professionals viewed the impacts of
climate change extending beyond physical health, impacting mental health and social wellbeing,
in addition to driving further health inequities based on social determinants of health. However,
the current expectations of the health professionals’ role, feeling a lack of capacity and available
time, and the politicization and fear of damaging the trusted relationship between clients,
community and the health professional were all identified as prominent barriers to
communicating climate change. Despite these challenges, participants saw potential for their role
to incorporate climate change communication and offered valuable insight into how this might
be achieved. Developing an approach to communication that recognises the unique context and
experiences of populations residing in the North, while respectfully navigating the tricky
sociopolitical landscape, will be imperative to effective communication and action engagement.
That being the case, participants advocated for further education and training in regard to climate
change health communication to significantly improve their capacity to incorporate the
communication into their role, as well as additional resources to support the development of
context-specific messaging they could use in their daily practice. These tools would help
participants, and health professionals across Northern Ontario, improve their capacity to
effectively engage in climate change communication to improve the health of the populations
they serve.

abstract:
This thesis examines the use of winch-assist technologies in logging operations
in the interior of British Columbia. The data used for this thesis is from a contractor’s
(located in Central B.C.) professional judgment as well as from other studies that took
place near this area. The objective of this thesis was to determine the economic
feasibility of winch-assist logging systems and compare the cost ($/m3) to cable yarding
systems. Comparisons between systems were made using a costing model that
determined the total cost of wood to roadside for three different systems including;
winch-assist, cable yarding with manual falling and cable yarding with mechanized
felling. In addition, a sensitivity analysis was used to determine how sensitive cost was
to a variety of variables. The analysis done is within the reasonable scope of the
requirements of an undergraduate thesis.The results found that cost ($/m3) was most
sensitive to productivity and machine utilization. A key finding of this thesis was cable
yarding systems with mechanized felling had the lowest overall cost. The implications of
the results and the applications of winch-assist logging systems are discussed further
throughout the thesis.

abstract:
The DNA molecule is constantly under attack from endogenous and exogenous sources leading to degradation by a variety of forms of damage. In this study current methods of in vitro DNA repair methods were evaluated for efficiency and for their relative ability to repair three different
experimentally induced forms of damage strand breaks, abasic sites, modified bases and crosslinks. GCMS was used to identify and evaluate effectiveness of repair methods for 16 different damaged products or modified bases. The methods were then used on ancient samples from
three sites 1) Daklah Oasis, Egypt; 2) Copan, Honduras; and 3) Çayonü Tepesi, Turkey. Success was achieved repairing these ancient samples depending on which method was used and what type of dam age was present. These results were consistent with the DNA damaged expected in
each of these sets of samples predicted hypothetically from the environment in which these samples were recovered. A new helicase dependant DNA polymerase. Phi 29 had an unexpected DNA repair capability notably on hydrolytic damage while the PreCR ™ enzyme repair mix was very effective at repairing the affects of oxidative damage. The DNA repair capabilities of 8 DNA repair systems were characterised and the demonstrated successful retrieval of DNA from 6 ancient DNA samples previously shown to be non-viable for genetic analysis were successfully
analyzed and amplified.

abstract: Study manipulated meaning process at study (congruent/incongruent meaning questions vs. no questions) and study/test form (picture or word at study crossed with picture or word at test). Particpants were 72 psychology students at Lakehead University, Thunder Bay, Ontario.

abstract:
A striking characteristic of episodic memory is that memory is better for pictures
than words—the picture superiority effect (Paivio, 1971). While evidence in support of
past explanations (e.g., dual-coding and sensory semantic models) has been inconsistent,
a growing body of behavioural (e.g.. Potter & Faulconer, 1975; Smith & Magee, 1980)
and neurological (Grady et al., 1998) evidence points to superior processing of meaning,
which is generally associated with pictorial presentations, as a major source of the
pictorial superiority effect The results of the present study—which manipulated meaning
processing at study (congruent/incongruent meaning questions vs. no questions) and
study/test form (picture or word at study crossed with picture or word at test)—revealed
that when potential ceiling problems of previous studies (e.g., Durso & Johnson, 1980;
Emmerich & Ackerman, 1979) are controlled, meaning elaboration 1) reduces, but does
not eliminate, picture superiority in Yes/No Recognition responses, 2) does not affect the
advantage of pictures over words in Remember (e.g., Tulving, 1985) responses but may
affect Know responses, and 3) does not affect the advantage of pictures over words in
Source Memory (e.g., Durso & Johnson, 1980) responses. Moreover, because the
benefits of reinstating the study form at test were as large for words as for pictures—for
recognition, remember, and source responses—the results imply that the processing of
pictures cannot be treated as including processing in common with words with the
addition of picture specific processing. Rather, the processing of pictures and words
must result in equally unique sources of information that differ in terms of their overall
memorability.

abstract:
Social and cultural adaptation may be issues of importance to students of Chinese
origin in Canada, where both Canadian-born and foreign-born Chinese students often
experience many problems of adjustment, including the challenge of cultural difference
to a new social context. The purpose of this phenomenological study was to provide an
in-depth description of the key factors that contribute to differences in the social
experiences of Canadian-born and foreign-born Chinese students, and to disseminate
results that could be used by policy makers to enable them to better understand and
address the needs, interests, and aspirations of students of Chinese origin in Canada. This
study employed a qualitative methodology to uncover and describe the internal meaning
of the participants’ lived experiences. This study occurred in a North-western Ontario
urban community with a Chinese Canadian population of approximately 300. Three
Canadian-born and three foreign-born Chinese students were interviewed in this study.
Semi-structured interviews with open-ended questions were adopted in this study to
allow the participants to express their views on their lives in Northern Ontario, Canada.
Four themes emerged: (a) perceptions of ethnic identity; (b) cultural integration; (c)
perceptions of academic performance and (d) the effect of Canadian education on career
options. The findings of this study indicated that Canadian-born Chinese students differed
from their foreign-born counterparts in the following areas: their viewpoints on ethnic
identity; their perceptions concerning acculturation; and academic performance. However,
both groups of students also shared similarities in their views about Canadian and
Chinese educational systems, teaching styles, as well as their career expectations.

abstract:
The purpose of this investigation was to compare the effectiveness of two types of
mountain bike front fork suspension systems for controlling ground reaction vibration at
the handlebar upon impacting a raised surface. A second purpose was to investigate the
effectiveness of these two suspension systems at maintaining ground-wheel contact
following impact
This investigation provided a direct measurement of handlebar vibration and
ground reaction forces at the front wheel. A rigid front end was compared to an elastomer
and a hydraulic suspension system each tested at their stiffest and softest settings. A
single subject was chosen to perform repeated trials over an AMTI force platform
modified with a 3 cm raised surface. Velocity and riding technique were controlled for
reliability and rider weight displacement was measured using strain gauges mounted on
the handlebar.
A shear quartz mode piezoelectronic accelerometer mounted to the handlebar
provided vibration measurements and the AMTI force platform measured ground reaction
forces. Mean curves for acceleration and ground reaction force were recorded and
calculated from repeated trials and used system comparison.
Results from the mean curve comparison of the suspension systems showed
reduced amplitude and frequency of vibration at the handlebar and improved
ground/wheel contact time for both elastomer and hydraulic systems when compared to
the mean curves for the rigid front end. Statistical analyses supported the mean curve
results indicating significant differences between the rigid and the suspension systems on all variables analysed at the .05 alpha level.
It was concluded that the hydraulic and elastomer systems reduced handlebar
vibration and improved ground-wheel contact when compared to the rigid systems for
this particular subject and bike combination. This investigation supports claims made by
manufacturers of suspension systems, that front suspension improves ground/wheel
contact and reduces transmission of impact energy to the rider at the handlebar.

title: Dielectric studies of molecular motions in some solids

subject:

Molecular dynamics

abstract:
Dielectric absorption of a number of nonpolar,
weakly polar and fairly polar molecules in the
pure solid state are studied. Measurements of these
solids using either a General Radio 1621 Precision
Capacitance Measurement System or a General Radio 1615-A
Capacitance bridge with appropriate temperature-controllable
cells are described. The glass transition (Tg)
measurements using the Glass Transition Measurement
Apparatus are also described. The experimental data as
a function of frequency at different temperatures are
subjected to analysis by a series of computer programmes
written in the APL language. The activation energy barriers for the dielectric relaxation processes were
obtained by the application of ;the Eyring rate equation.
The dielectric absorption of some spherically shaped
nonpolar molecules are observed, the energy
barrier values of which agree well with those found from
other measurements. It is suggested that this absorption
might be due to the interaction of the radiofrequency
radiation with an induced moment which results from
multiple interaction.
Of the spherically-shaped polar molecules
examined, both molecular and co-operative relaxations
are detected in all the alkylhalides. Dielectric data
for molecular relaxations are described by the Cole-Cole
plots, whereas those for co-operative motion, in most
of the cases, cannot be accurately represented by the
Davidson-Cole skewed-arc function.
Low temperature molecular relaxations are
detected in some nonpolar and weakly polar aromatic
hydrocarbons. The results of these molecules are used
to suggest a possible correlation between enthalpy and
entropy of activation and ionization potential and enthalpy
of activation. The dielectric absorption of apparently
nonpolar aromatic hydrocarbons are explained on the basis
of quadrupole or octupole induced moment which may be
of significant magnitude when the internuclear distances
are small as in the solid state.
Co-operative relaxations of some of the nonpolar
and weakly polar hydrocarbons are found above the
glass transition temperature (Tg). The variation in the
energy barrier values for these relaxations are explained
in terms of molecular interaction which is measured either by ionization potential or by the stretching frequency
of a suitable solute molecule such as pyrrole (e.g. N-H)
with which the aromatic hydrocarbon can form hydrogen bond.
The molecular relaxation processes of a number
of rigid arylhalides in the pure solid state are found
almost in the same temperature and frequency regions as
those found in different viscous media. A similar enthalpy
of activation values are also observed. For some rigid
heterocyclic molecules, except N-methyIpyrrole, no molecular
relaxation is observed and this could be accounted for
by the crystal structure and the lack of free volume for
these molecules to relax.

abstract:
This phenomenological study of six Chinese graduate students coming from mainland
China, explored their lived experiences in North America. From the qualitative data analysis,
five themes emerged: (a) the experiences of the Chinese graduate students with language; (b) the
Chinese graduate students’ academic concerns; (c) the experiences of the Chinese graduate
students with cultural differences; (d) the job related experiences of the Chinese graduate
students in North America; (e) the advantages of a North American education for China. The
study has provided some factors that influenced these six Chinese graduate students who came to
North America to study and explored their reactions to the educational system in North America.
It has also highlighted aspects of education in North America that can be used or adapted to a
Chinese setting. Further, the study has shown that there are many things that one can learn from
the lived experiences of these students from mainland China. The Chinese graduate students,
based on their working experiences in North America, reported no big gender differences in
finding decent jobs. The study found no big differences between science and non-science majors
Chinese graduate students when studying or working in North America. The study has provided
some suggestions for future research in the area of students’ experience with language in North
America, their motivation for selecting majors and finding jobs in North America whether based
on their research interests or not, and the adaptability of these students to American society. It
also suggested that how culture affects working relationships in China and in North America and
how Chinese graduate students celebrate American holidays after they arrive in North America
would be worthy subjects for further investigation.

abstract:
The purpose of the study was to investigate whether secondary school teachers used Glasser's choice theory in classroom management and how it was operationalized and/or to describe the alternative approaches they may be taking to classroom management. The study was a qualitative case study of five highschool teachers. Methods included semi-structured interviews and fieldnotes. The study explored the perceptions of five highschool teachers regarding the efficacy of Glasser's (1998a) choice theory in terms of their classroom management strategies and personal responsibility. According to Glasser, individuals achieve responsible behaviour when they attempt to satisfy their own needs without depriving other people of the same opportunity.
As a result of data analysis four themes (goals of classroom management, strategies for classroom management, teachers’ perceptions of the reasons or misbehaviour and teachers’ perceptions of the characteristics of effective teachers) emerged. The participants’ perspectives illuminated several of Glasser’s (1988,1998a, 2002,2004) beliefs including the quality world, student needs, the importance of a positive teacher/student relationship, the importance of meaningful work, student responsibility,
positive feelings, and the positive effects of encouraging, supporting, listening and caring.  In addition, participants noted that although student choice is important for a number of reasons, teacher control is also necessary to ensure structure and safety.
It was determined that, although choice theory was not specifically adhered to, the use of elements of choice theory illustrated the power of choice theory in that as teachers negotiated the tensions of classroom management they indeed did use a lot of ideas consistent with Glasser (1998a).

subject: Infection prevention

abstract:
Outbreaks of infectious diseases, such as SARS have highlighted the importance of infection
prevention and control practices. Diseases such as tuberculosis (TB) continue to persist and pose a
threat if not understood and managed appropriately. Certain high risk groups exist for TB infection
and disease, and the elderly are included in this group. The elderly living in long-term care homes
(LTCH) are a vulnerable population and as such, these health care facilities need to be aware of
and to develop plans to respond to TB within their institutions.
In Hamilton, approximately 3 to 4 cases of active TB are found each year in staff or residents
of LTHC’s. Based on experience working with these facilities, a knowledge gap was noted related
to TB infection prevention and control practices. Hamilton Public Health Services TB Control
Program conducted a learning needs assessment to help understand the gaps in knowledge for staff
working in LTCHs. In addition, we were able to understand their preferred method of learning.
The findings illustrated that healthcare staff working in long term care homes had a knowledge
deficit related to TB. It was determined that TB education sessions should be provided when hired
and at subsequent intervals to reinforce learning.
Based on this information and as suggested by the literature, a TB education program (TBEP)
was developed. The goal of the TBEP is to develop and implement a comprehensive TB education
program (TBEP) for LTCH healthcare staff in Hamilton by the end of 2010 to enhance TB
infection prevention and control measures. Training sessions will be offered to all LTCHs in
Hamilton by TB-expert public health nurse. An evaluation component has been included as an
essential element to facilitate enhancements to the TBEP.

abstract:
The discovery of a class natural products with anti-cancer properties, the enediynes, has
stimulated interest in their research. Due to their cytotoxicity, these compounds are not feasible
for use in cancer treatment, however, synthetic work has centered around improved stability,
reduced toxicity and elucidation of the mechanism of the Bergman cyclization reaction.
Protocols utilizing palladium-catalysed cross coupling reactions have been used extensively in
the synthesis of enediyne analogues. Little work to date has investigated the effect of
heteroatoms on the success of coupling reactions, thermal Bergman cyclizations and
photochemically induced cyclizations. In this thesis, a synthetic study involving the coupling
reactions o f nitrogenous aromatic halides, halotriflates and a series of alkynes will be presented.
Several enediyne analogues were synthesized in moderate to high yields, isolated and
characterized. In general, it was observed that nitrogen heteroatoms increase the reactivity
toward Sonogashira coupling reactions. In order to examine the effect o f resonance and
inductive effects on the reactivity under Sonogashira conditions, a series o f competitive reactions
between m- or p-substituted aryl iodides and iodobenzene were performed. In general, electron
withdrawing substituents in the m- or p-positions increased the reactivity, while electron donating substituents decreased it. It was observed that resonance effects have a larger effect on
reactivity than inductive effects. Thermal and photochemical cyclization studies were performed
for the nitrogenous aromatic enediynes synthesized. None o f the enediynes were observed to
cyclize thermally, while only the TMS- and phenyl-substituted enediynes were observed to
photochemically cyclize.


title: Relationship between cognitive style and informed decision making

subject: Cognition Decision-making Intellect

abstract:
In this study, the relationship between children's cognitive styles and their ability to use
informed decision making was
investigated.
Thirty-nine Grade Three students in Thunder Bay participated in a seven week, teacher-researcher
designed decision making unit. This unit promoted metacognitive awareness and instructed students
in a decision making method using simple, logical,
age-appropriate strategies. It was the expectation that there would be an improvement in the
decision making ability of these students, and that the reflective, field-independent student would
perform the most efficiently in decision making activities.
The reasoning ability, the cognitive styles - reflective/impulsive and field-dependent/independent,
 and  level of decision making were assessed. The following measures were employed to determine
these variables: Raven's Coloured Progressive Matrices (Raven), Matching Familiar Figures Test
(Kagan), The Children's Embedded Figures Test (Witkin), and   the
Draw-a-Person Test (Machover).
Each participant's performance level was then determined in a posttest situation, and again in a
second posttest situation nine weeks later. Means, standard deviations and correlation coefficients
were calculated.
Results indicated that there was improvement in the participants' level of decision making. This
improvement was maintained at the second post test nine weeks later. Results also indicated that
Grade Three students' decision making performance may be affected more by their
impulsive/reflective nature than by their level of field-independence/dependence.
strategies which consider the reflective/impulsive nature of young children and incorporate
age-appropriate strategies hold the greatest potential for enabling students to become efficient
decision makers and critical thinkers.

abstract:
Renewable forms of energy are of significant interest in today’s economies. Biofuel is a renewable fuel produced by biological means. Biofuel is very useful because it does not have a finite supply, and it produces fewer pollutants than fossil fuels. Recently, there is a serious concern about future of fossil-based fuels due to increasing price of crude oil around the world, depletion of its sources, several important environmental issues (greenhouse effect and global warming) and increasing energy demands. Thus, this situation has imposed researchers for further exploring the renewable energy sources to produce environmentally friendly fuel that not cause any pollution to the atmosphere. Additionally, nowadays, supplies like plants, organic wastes, and agricultural products are often used to produce biofuel. Until now, bioethanol and biodiesel are the most widely produced and used as biofuel.
Biodiesel-derived crude glycerol and lignocellulosic (from cell walls of woody plants) biomass are two attractive low-cost renewable resources for biofuel production. Efficient and cost-effective production of biofuel from these sources through biotechnological methods depends on the development of a suitable bioconversion process. The main aims of this study were to i) isolate and characterize the novel as well as highly efficient cellulase or glycerol dehydrogenase (GDH) producing bacterial strains, and ii) optimize the enzyme production parameters during fermentation. These strains could be considered for the biorefinery industry for hydrolysis of lignocellulosic biomass or bioconversion of glycerol so as to accelerate biofuel commercialization.
In this research project, three potential glycerol metabolizing strains of Serratia sp. were
isolated from paper mill waste of Resolute Forest Products, Thunder Bay, Ontario, Canada. The glycerol bioconversion abilities of the promising strain S. proteamaculans SRWQ1 were analyzed ii
using crude glycerol (byproduct from biodiesel production) as the sole carbon source. During shake flask fermentation under aerobic conditions at an optimal incubation temperature of 25°C, the strain SRWQ1 used 98% of the crude glycerol and produced 18.43 ± 1.55 g/L 2,3-butanediol (BDO) and 8.38 ± 0.76 g/L acetoin, with yields of 0.4 and 0.06 g/g, respectively. When the culture medium (minimal salt medium) was supplemented with 50 g/L of glycerol as the sole carbon source, and 5 g/L yeast extract and 5 g/L peptone as the nitrogen sources, the maximum glycerol dehydrogenase (DGH) activity was 408.69 ± 0.069 U/mg protein. The incubation temperature, pH, glycerol concentration and nitrogen sources are the most important factors ruling the GDH activity. Slightly acidic initial pH (pH 6.0) led to enhanced GDH activity and biomass production. This is the first report that S. proteamaculans species can efficiently convert glycerol to produce green products 2,3-BDO and acetoin.
Twenty cellulase-producing bacterial strains were isolated from Kingfisher Lake, Ontario, Canada, and screened for cellulase activity using the carboxymethyl cellulose (CMC) agar plate assay. Isolates showing large halos of depolymerization were further assayed to quantify enzyme production ability and identified by using 16S rDNA sequence analysis. The molecular weight of crude cellulase samples was determined ∼50 kDa with sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). The Bacillus strain IM7 showed the highest carboxymethyl cellulase (CMCase) activity (17.7 ± 0.17 IU/mL) after 48 h of incubation at a yeast extract concentration of 15 g/L. A temperature of at 30°C and pH 5.0 were the optimal conditions for cellulase production. The highest activity (24.59 ± 0.09 IU/mL) was recorded when the culture medium was supplemented with 2% mannose as a co-substrate. The increased glucose content by using mannose in the hydrolysate process resulted in the dramatic increase in enzyme activity.


title: Durability and mechanical properties of Portland cement concrete that utilizes crumb rubber as an alternative fine aggregat

subject:
Portland cement
Crumb rubber
Discarded tires as a concrete aggregate
Reclaimed tire rubber

abstract:
This research project investigated in an intensive experimental program the influence of using crumb rubber in the mechanical properties and durability of Portland cement concrete mixtures. Crumb rubber is produced from waste tires which pose significant problems in the waste management sector. The incorporation of crumb rubber in some concrete infrastructure will help reduce the number of tires stockpiled annually.
Two rounds of batching and testing were undergone. One round occurred over the summer of 2017 and the other in the spring of 2018. The water cement ratio used in all mixes containing crumb rubber was 0.45. One mix with a water cement ratio of 0.4 was also prepared to give comparative values as to what would be obtained in a pavement structure designed meeting MTO criteria. Crumb rubber replaced a percent volume of the fine aggregate. Batches with crumb rubber substitution in amounts of 0 % to 25 %, in 5 % increments were prepared.
Each mix was tested for 28-day compressive strength, flexural strength, splitting tensile strength, bulk resistivity, surface resistivity, rapid chloride penetration and freeze-thaw testing (ASTMC39, ASTMC78, ASTMC496, ASTMC1202, ASTMC666, respectively). The 28-day compressive strength, flexural strength and splitting tensile strength were all observed to decrease with the increase in crumb rubber.
It was found that a 25 MPa 28 day compressive strengths are possible with crumb rubber replacing as much as 15% of the fine aggregate. The corresponding modulus of rupture of the mixture was 5.2 MPa compared to 5.9 MPa in a similar concrete mixture but without crumb rubber. The splitting tensile strength for the mixture containing 15 % of the fine aggregate crumb rubber was 2.9 MPa which is 90 % of the splitting tensile strength of a similar concrete mixture but with no rubber.
Bulk resistivity, and surface resistivity as a function of the rubber content and the effect of the freeze freeze-thaw durability all improved, however the improvement was not statistically significant. The bulk resistivity was found to be 6.0 kΩcm for the mixture with 15 % of the fine aggregate crumb rubber and 5.9 kΩcm for the mixture containing no crumb rubber. Similarly, for surface resistivity the values were 17.4 kΩcm and 17.1 kΩcm for the 15 % and 0 % crumb rubber contents, respectively.
The rapid chloride penetration values did improve, but again not significantly. In fact, the classification according to ASTM C1202 did not change. All samples were of moderate penetrability.
For every 5 % increase in rubber as a portion of fine aggregate, it was found that the plastic air content increased 0.5 % above the measured mechanically entrapped air.
Durability factors were not able to be calculated from freeze-thaw tests due to low fundamental frequency readings before any cycles. However, a plot of the relative dynamic moduli shows that the introduction of crumb rubber did significantly improve the durability of the concrete mixture. After 300 cycles the relative dynamic moduli of the mix with a 0.4 water cement ratio and no crumb rubber was 483, whereas a mix with a 0.45 water cement ratio and 15 % crumb rubber had a relative dynamic modulus of 773.


title: A proposed moderation model of socially prescribed perfectionism and mattering to predict maladjustment in first-year university students

subject: Psychological well-being (university students)

abstract:
Emerging adulthood (ages 18-29) is recognized as a stage associated with unique developmental
needs and transitions. Moving from high school to university is one life transition that demands
for multiple adjustments and leaves emerging adults at risk for maladjustment (e.g., experiencing
psychological or academic distress). As such, it is important to examine explanatory models of
factors that predict and prevent maladjustment in first-year university students. The current study
tested a moderation model to explain maladjustment in first-year university students. It was
proposed that socially prescribed perfectionism would be associated with greater maladjustment
(operationalized in the current study as poor psychological well-being, depressive symptoms,
and academic distress), and mattering (i.e., feeling important and significant to others) would be
associated with lower maladjustment. Moreover, it was hypothesized that mattering would be a
significant moderator of the relationship between socially prescribed perfectionism and
maladjustment. First-year university students (N = 152) at Lakehead University completed a
series of self-report measures assessing socially prescribed perfectionism, mattering,
psychological well-being, symptoms of depression, and academic distress. As expected,
hierarchical regression analyses showed that socially prescribed perfectionism was a predictor of
greater maladjustment, while mattering was a predictor of lower maladjustment. Further,
mattering significantly moderated the association between socially prescribed perfectionism and
depressive symptoms such that, low levels of mattering strengthened the relationship and high
levels of mattering diminished the relationship. However, mattering did not significantly
moderate the link between socially prescribed perfectionism and psychological well-being or
academic distress. The results suggest the need for university institutions to consider mattering as
a target to enhance university student well-being and academic success.


title: Weight distribution patterns among golfers of different skill levels

subject: Putting (Golf)

abstract:
The purpose of the study was to determine whether a significant relationship existed between the
skill level of golfers and the weight distribution patterns exhibited during the putting stroke. A
differential research design was utilized to place thirty six male subjects into groups of low
(0-5), medium (6-14), and high (15-25) handicap (hdp) levels. Subjects performed ten trials over
ten and fifteen foot putting distances. A 3 X 2 (groups by distances) analysis of variance with
repeated measures on the second factor was used to determine whether kinetic measures and total
putting accuracy scores were different across groups. The normalized vertical force F(l,33)=9.03,
p=.005, and the final ball position (degrees) were found to be significantly different for each
putting distance, F(l,33)=27.31, p<.001. The effect of skill level on the final ball position
(degrees) was dependent upon the distance of the putt, F(2,33)=6.83, p=.003. The low and medium hdp
groups were successful with a significantly greater number of putts than the high hdp group,
F(2,33)=6.67, p=.004. All groups made more putts from the ten foot distance than the fifteen foot
distance, F(l,33)=67.94, p<.001. No significant relation existed between the total excursion,
r=.005, and the normalized vertical force, r=-.022 with the putting accuracy scores. Similarly,
there was no significant relation between the total excursion, r =.004, and the normalized vertical
force, K =.096 with the skill level of subjects. A stepwise multiple regression analysis determined
that
no dependent measure was a significant predictor of skill level at
a critical level of .05. The hdp groups were significantly
different with regard to the age at which they started playing
golf, F(2,33)=5.723, p=.007, the average number of three putt
greens per game, F(2,33)=3.488, p=.042, and the number of
tournaments entered each year, F(2,33)=4.318, p=.022. All other
kinetic measures were nonsignificant.


title: Labour market segmentation and differing retirement arrangements

subject:
Labor supply
Retirement (Economic aspects)

abstract:
Labour market segmentation theory was developed as an
explanation for ongoing poverty among some groups of people.
According to this theory, the problem is in the structure of the
work world, rather than in individual characteristics. The
research in this paper examines the relevance of this theory for
retirement arrangements. An investigation of 154 retirement
arrangements within 132 companies, and interviews with 486
retirees, yielded evidence that there are differences not only in
the resulting pension amounts, but also in the types of plans,
and the terms therein, offered to workers, by segment. Thus, the
segmentation that began in the labour force is extended into
retirement. As well as making a contribution to labour market
segmentation theory by providing empirical evidence of the
differences in retirement arrangements for the various segments,
this study offers an alternative method for the
operationalization of the segments.

abstract:
The purpose of this study was to answer the question, “Do middle distance
track athletes experience hematuria with their normal competitive season interval
workouts?” Secondary purposes were (1) to identify the type of workout most
associated with hematuria as workouts were classified on the basis of intensity
and duration and (2) compile supplementary measures associated with these
workouts that would hopefully help to point towards a cause. The participants for
this study were a group of seven male and three female (n=10), healthy,
experienced middle distance runners aged 19-56 years who were all members of
the Lakehead University Athletics Club in Thunder Bay, Ontario. Over the course
of four weeks, subjects underwent urinalysis before and immediately following,
their twice weekly interval sessions, over the course of a four week period. Pre-workout
urine samples were examined for pH, specific gravity, and the presence
of hematuria, proteinuria, and granular casts using reagent strip analysis. Positive
hematuria samples precluded follow up analysis on that subject. Post workout
urine samples underwent reagent strip analysis for pH, specific gravity,
hematuria, and proteinuria. Positive specimens for hematuria were analysed
under a microscope to calculate a more accurate red blood cell (RBC) and
granular cast loss. Subjects were asked to provide follow-up samples until the
reagent strip indicated a negative result for hematuria. Supplementary measures
of 4min. peak blood lactate (pBLa), a subjective rating of perceived exertion
(RPE), and the amount of time the subject worked above 65% of their VO2max (65% VO2max) were used to indicate if a specific level of exertion was required to
induce hematuria in middle distance track runners. Urine sampling indicated that
middle distance track runners do experience hematuria, with nine of the ten
subjects providing a positive sample at least once during the four week period.
This study was unable to prove which of the thirteen workout classifications had
the greatest incidence of hematuria because o f the unequal number of subjects
completing each workout classification The results did demonutate that the
greatest incidence of hematuria occurred following workouts of 800 m and 1500
m running pace with durations of 1001- 4000 m. The individual mean loss of red
blood cells (RBC) per high power microscopic field (HPF) for the study group
ranged between 2-81 RBC. All positive samples contained microcytic whole
RBC. Protein and granular casts were observed regardless of the presence of
RBC. A clear relationship between RBC loss and the supplementary measures of
exertion was not observed.


title: Paleomagnetic secular field variation and rock magnetism of some early holocene (<9900BP) postglacial lacustrine sediments near Thunder Bay, Northwestern Ontario, Canada

subject: Regional geology of northwestern Ontario

subject: Rock magnetism

subject: Paleomagnetism

abstract:
Paleosecular magnetic changes through a 1.5m section of post-glacial lacustrine deposits
are strongly influenced by mineralogy and differential compaction. The sediments chiefly
comprise clay and, in the lower one third part of the section, rhythmites which vary from ~2mm
to ~Scm in thickness. 125 paleomagnetic specimens were collected in total from the 1.5m section.
Anisotropy of magnetic susceptibility and anisotropy of anhysteretic remanent magnetization
identify a magnetic fabric with maximum susceptibility parallel to the bedding plane of the
sediments and with a preferred northwest-southeast axis, probably indicating paleo-current
alignment. Minimum susceptibility represents the pole to bedding, due to grain alignment.
Incremental acquisition and demagnetization of isothermal and anhysteretic
magnetizations and the orthogonal three-axis test indicate that the sediments contain two
magnetic phases with different coercivities. Magnetic hysteresis measurements (clays n=226; silts
n=37) show that clay is dominated by single domain magnetite and hematite (means of
M5=58.47±9.22Am2
, Mrs=17.12±27.22Am2
, Hc=21.09±7.69mT, Hcr=62.04±4.09mT) whereas silt
is dominated by pseudo-single domain and single domain magnetite (means of
M5=681.0±395.9Am2
, Mrs=163.2±84.75Am2
, Hc=26.07±2.94mT, Hcr=56.08±3.17mT). The silt is
dominated by magnetite, whereas the clay carries both hematite and magnetite.

Food security (Canada)

abstract:
Food security exists when all people, at all times, have physical and economic access to
sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active
and healthy life (Rome Deceleration of World Food Security, 1996). The most recent report on
food insecurity shows that an estimated 3.7 million Canadians (14.7% o f the population)
nationwide experienced food insecurity in 2000-2001 (Ledrou & Gervais, 2005). Ledrou &
Gervais (2005) reported seven percent of Canadians experienced the most severe form of food
insecurity: they or someone in the household did not have enough to eat because of a lack of
money. Since 1989, there has been an increase o f more than 184, 309 hungry children and a
118% increase in the use of food banks throughout Canada (Canadian Association of Food
Banks, 2005).
Canada recognized the importance of food security in April 2005 by voting in favour of
the UN Commission on Human Rights ‘right to food resolution’. This pledge supports a previous
commitment that includes Canada’s signing of The Rome Declaration on World Food Security
along with 186 other countries in 1996. Signing this non-binding treaty galvanized the Canadian
government into action and resulted in the creation of Canada’s Action Plan for Food Security
(1998) and a government branch called the Food Security Bureau. However, after several years,
food security conditions have failed to improve throughout Canada.

title: Depression, quantity of social interaction, reciprocal self-disclosure, and perspective-taking in the elderly

subject:
Aged Psychology
Depression, Mental
Self-disclosure

abstract:
The present research was designed to investigate the
relationships among; a) depression, b) the quantity of
social interaction and, c) the quality of social
interaction in the elderly. Twenty-three residents aged
72 to 98 of a rural senior citizens home were tested. The
subjects were administered the Zung Self-Rating Depression
Scale and Flavell's (1975) measure of visual
perspective-taking. The quantity of social interaction
was measured by the subject's self-reports of their
frequency of interaction with various groups of people and
the number of persons they talked to most frequently. The
measure of the quality of social interaction was derived
from a round robin procedure based on the subjects'
reported self-disclosure to peers. This enabled the
identification of subjects who had relationships
characterized by reciprocal intimate disclosures - or
confidants. The analysis provided partial support for the
validity of the quantity and the quality of social
interaction measures. Consistent with previous research,
depression was negatively correlated with one measure of
quantity of social interaction, the number of peers with
whom the subject frequently talked. Contrary to
expectation, perspective-taking was not significantly
correlated with the measures of quantity of social interaction or the measures of reciprocal disclosure.
Contrary to the quality of social interaction research, the
intimacy of the subject's disclosures and the intimacy of
the target's disclosures were not significantly correlated,
indicating that disclosure patterns among the elderly were
not reciprocal. In addition, having a relationship
characterized by reciprocal intimate disclosure was
positively, rather than negatively correlated with
depression. This indicates that the more depressed an
elderly individual is, the more the individual had in
objective terms - confidants. One interpretation of this
latter finding was advanced, that depressed elderly
reciprocate personal information in the form of negative
perceptions or complaints.

subject:
Magnesium Surfaces
Thin films
Molybdenum Surfaces

abstract:
Epitaxial growth of thin films on solid substrates is of great interest because it
allows for the creation of materials with morphologies and chemical compositions which
are not found in nature. The size o f electronic devices is continually being decreased to
minimize space requirements. Surface related phenomena become more important in the
design of these devices as the surface to volume ratio continues to increase. Metal
surfaces are very important to the development of heterogeneous catalysis. Often very
expensive metals are used. Since catalysis is purely a surface phenomenon the cost can
be greatly reduced by growing thin clusters of this expensive metal onto the surface of a
more inexpensive one. Metal on metal film s are also used for data storage. Large
resistive changes in a magnetic field for certain devices composed of alternating thin
layers o f metals are being used to create the next generation of disk drives. A greater
understanding o f the properties o f surfaces is crucial to the development of these areas.

abstract: A case study of music teacher Diane Garrett, of Thunder Bay, Ontario and the influence and impact on the students of Fort William Collegiate Institute, a high school in Thunder Bay.

abstract:
The purpose of this study is to explore the expert teaching of music teacher Diane
Garrett, of Thunder Bay, Ontario. The qualitative case study method set within a constructivist
framework was utilized. Seven interviews were conducted with primary participant, Diane
Garrett. In order to further explore her influence and impact on the students of Fort William
Collegiate Institute in Thunder Bay, Ontario, six former students and two colleagues were
interviewed. Archival data, in the form of artifacts and documents, were also examined.
The existing body of literature about expert teachers reveals that they share similar
personality characteristics (Collinson, 1996; Porter & Brophy, 1988). As well, expert teachers
possess a highly developed sense of pedagogical knowledge, expressed in theoretical knowledge
and practical teaching skills (Berliner, 1988; Leinhardt & Greeno, 1986; Sternberg & Horvath,
1995).
Three themes emerged from the data: building a family, teaching and learning, and
striving for excellence. Expert music teacher Diane Garrett encouraged the development of a
family-like atmosphere in the classroom, and acted as a parental figure, nurturing, caring and
facilitating the emergence of a “musical family” within the F.W.C.I. Music Department. As
well, she acted as a role model of musicianship and high performance standards for her students.
These themes are discussed as they relate to current literature, educational philosophies (Elliott,
1995; Palmer, 1998; van Manen, 1996), and music teaching practices. In this study, the notion of
the expert teacher is reinvented in that the teacher as a parental figure emerges as the most
significant finding, providing the field of expert teaching with a new concept and a different set of variables to consider. By exploring Diane Garrett’s combination of mastery in teaching and
musicianship and the relationship to her students’ achievement, the myth - “those who can do,
those who can’t teach” - is debunked.
