title: Rooming-in and neonatal abstinence syndrome : a systematic review

subject:
Neonatal Intensive Care Unit (NICU)
Neonatal Abstinence Syndrome (NAS)
In-utero opioid exposure
Caring of newborns with NAS

abstract:
Aim: The purpose of this systematic review was to critically examine the literature about the effectiveness of rooming-in compared to traditional care settings such as the Neonatal Intensive Care Unit (NICU) for newborns with Neonatal Abstinence Syndrome (NAS).
Background: NAS is a multi-system disorder observed in newborns experiencing withdrawal following in-utero opioid exposure. Rooming-in may be beneficial to newborns with NAS as outcomes may reduce the need for pharmacologic treatment, the duration of pharmacologic treatment, and shorten length of stay (LOS). Although the studies support rooming-in, information in this area of research is limited. Based on the little evidence known, rooming-in may provide beneficial outcomes for newborns with NAS symptoms. Therefore examining the outcomes of NAS and rooming-in may be insightful to the contribution of research in this area of NAS.
Method: A systematic search exploring the effects of rooming-in and NAS in newborns was conducted using the following electronic databases: Pubmed, Proquest, PsychoInfo, OVID Joanna Briggs Institute of systematic reviews, CINAHL, Nursing and Allied Health, Evidence-Based Medicine, Web of Science, Cochrane Database of Systematic Review, DARE and Medline (EMBASE). Studies were eligible for inclusion in the review if they fulfilled the following criteria: (1) reported outcome data for newborns with NAS and rooming-in care, (2) primary studies, (3) quantitative studies with a comparison group, (4) peer-reviewed, and (5) were published in English. Selected studies were assessed by two appraisers using the JBI Standardized critical appraisal checklist for cohort studies.
Findings: The search identified two hundred sixteen (n = 216 studies). An additional two studies were retrieved through a forward citation search. Following removal of studies that did not meet the inclusion criteria, six studies remained for the systematic review. The results from this review suggest that rooming-in has the potential to improve NAS outcomes including: a decreased need for pharmacologic treatment, a shorter duration of pharmacologic treatment, a reduction in hospital stay, and healthcare cost savings. These findings support the need for rooming-in to care for newborn with NAS symptoms.
Conclusion: The findings from this systematic review suggest that rooming-in for newborns with NAS was effective in reducing the duration of pharmacologic treatment, need for pharmacologic treatment, and length of hospital stay compared to traditional care settings. Rooming-in should be explored as a care model for select newborns however further investigation is required with larger sample sizes and a more detailed description of rooming-in in order to gain further insight.


title: Attentional and psychophysiological responses to seasonal and eating stimuli in seasonal depression and disordered eating

subject:
Seasonal depression
Disordered eating
Attentional bias
Facial electromyography

abstract:
Research indicates similarities in clinical presentation between seasonal depression and bulimia nervosa with respect to disordered eating symptoms such as overeating, carbohydrate craving, weight gain and seasonal pattern wherein more severe symptoms are reported during the winter. Despite the overlap, there has been no research on the specific cognitive profiles and schemas of each psychological disturbance that might help to distinguish the two conditions. This study examines the cognitive profile and psychophysiological reactions of individuals with seasonal depression symptoms, those with disordered eating, and healthy controls through the use of a modified Stroop task, an incidental recall task, and facial electromyographic (EMG) recording during an image viewing task. Results showed that those with seasonal depression symptoms were distinguished from healthy controls on the basis of higher zygomaticus major peak amplitude when viewing images of food. All three groups rated the summer images and binge food images more positively. Supplementary regression analyses were run on the entire dataset to examine the extent to which seasonality, typical depression symptoms, atypical depression symptoms, and the presence/absence of disordered eating symptoms might predict performance on the experimental tasks. Higher atypical depression symptoms were associated with more nonresponses for nonbinge food words on the modified Stroop task as well as higher zygomaticus major peak amplitude
when viewing images of binge foods, non-binge foods, and winter scenes. The presence of disordered eating was also associated with higher zygomaticus major peak amplitude when viewing winter scenes. In conclusion, the study did not find support for the position that there might be different cognitive profiles for seasonal depression and disordered eating. The findings are discussed within the context of the strengths and limitations of the study.


title: Green(ing) schoolgrounds in the Toronto District School Board : an investigation of potential

subject: School grounds Design Ontario Toronto

abstract: Literature review includes : school ground greening research (learning, social & behavioural development of children and adults, restoration and behavior, play, environmental awareness and stewardship, health, health recovery, illness prevention and health promotion, safety) ; critical environmental education ; school ground greening in Canada.

abstract:
As school ground greening becomes more common in schools around the world, researchers from
a number of disciplines and fields have begun to investigate the potential outcomes of the
differing approaches, traditions and contexts of these projects. Much of the research on these
initiatives has been performed within a single school, m aking it difficult to understand the nature
of the impacts across a large sample of schools. In this study, I explored school ground greening
projects at a school board level of analysis, using the Toronto District School Board (Ontario,
Canada) as my site of investigation. I used a mixed-methods approach: 1) 149 questionnaires
were completed by administrators, teachers, and parents associated with 45 school ground
greening initiatives in the school board; 2) 21 in depth follow-up case studies were conducted at 5
schools across a range of socio-economic statuses; and 3) 6 interviews were conducted with
school board administrators and an Evergreen employee. In this dissertation, I work within a
critical environmental education framework to present and discuss findings of several key areas,
including: 1) the profiles of individuals and schools who are involved in school ground greening
projects; 2) the profiles o f the actual projects; 3) the process of greening school grounds; 4) the
impacts of green school grounds; and, 5) the key limiting and enabling factors for these
initiatives. I conclude with a discussion of future research priorities.

Anti-homophobia education
Homophobia

Queer pedagogy

abstract:
Most schools in Canada are unsafe spaces for queer youth or those perceived by their peers as queer.
Gay/Straight Alliances (GSAs) and other LGBTQ+ inclusive groups exist in schools with the goal of
mitigating and working against homophobia and transphobia. Homophobia, heterosexism,
heteronormativity, and transphobia are consistent forms of oppression in K-12 schooling in Ontario.
Typically, it is straight teachers who lead GSA-type groups and are committed to LGBTQ+ equity work
in their schools despite often being under-supported by their colleagues, supervisors, and school board
policy. In addition to the other demands of their profession, teachers who take on allyship in their
already busy professional lives should be recognized for their efforts and hard work. However, most
allies fall short of acknowledging or mitigating against their own straight privilege. Given the role
straight teachers play in GSAs, this research analyzes the role and experiences of straight teacher ally
activists working with LGBTQ+ students. Guided by the research question: How can straight teacher
ally activists move beyond the limits of anti-homophobia education by challenging heteronormativity
and heterosexism in schools?, I suggest that the overall effectiveness resisting normalized
heterosexuality through anti-homophobia efforts is limited. Teacher allies should work toward queering
school spaces by examining their own straight privilege as a starting point. This research stands as a call
to action for policy makers, school board administrators, and leadership to provide mandatory training
for all staff that zeros-in on straight privilege and heteronormativity as a way to resist its dominance.
Following a manuscript-style, the research findings are reported in three manuscripts written and
formatted for submission to scholarly journals.

subject: Pulse width modulation

abstract:
This thesis presents five different nonlinear control techniques for voltage regulation of a
DC-DC buck converter operating in continuous conduction mode. A state space
averaging model is derived from a non-ideal buck converter circuit with the consideration
of resistances of each component.
Based on this model, different nonlinear control techniques have been developed to
control the DC-DC buck converter. These include backstepping control, sliding mode
control, backstepping sliding mode control, adaptive backstepping control, and adaptive
backstepping sliding mode control. All these proposed controllers have been evaluated by
computer simulation and implemented on the DC-DC buck converter which is built for
this thesis.
Simulation and experimental results show that all the proposed controllers are able to
stabilize the closed loop system and to achieve satisfactory voltage regulation
performances under source voltage variations and load changes.

abstract: In almost all populations there is a significant sex difference in the rate of depression, with women being twice as likely to be depressed as compared to men (Bebbington, 1996; Kuehner, 2003) Numerous theories have been proposed in an attempt to explain this difference, with one such theory being Jack's (1991) Silencing the Self Theory which poses that, in adherence to the traditional female role, many women self-silence in an attempt to maintain their intimate relationships, which increases the risk of depression (Jack 1991). However, the relationship between self-silencing and depression is not necessarily direct thus suggesting that another variable, such as social support, may be moderating the relationship.


title: Sex differences in jealousy: investigating infidelity types and rival characteristics using animated videos

subject: Jealousy

subject: Commonality of infidelities

subject: Evolutionary pressures on jealousy

subject: Sexual versus emotional infidelities

subject: Rival characteristics

subject: Jealousy-related emotions and action tendencies

abstract: In this study, romantic jealousy, infidelity types, and rival characteristics (height, weight, facial attractiveness, strength, and social status) are explored from an evolutionary perspective. Several studies have previously investigated this issue with results suggesting that jealousy is an evolved psychological mechanism (as opposed to a purely social construct). Participants were presented with animated videos of jealousy-provoking situations and asked to report, using visual analogue scales, on the intensity with which they would expect to experience a wide range of jealousy-related emotions. Despite a replication of the original findings when using only the written forced-choice question, the video paradigm found no evidence for the hypothesis that women and men are differentially sensitive to sexual and emotional infidelities. However, women reported more of an emotional response to the infidelity videos than men, and participants reported more of an emotional response to the sexual versus the emotional infidelity video. Further, while participants did perceive differences in the attractiveness of the various rival characters created, these rival characteristics were not found to have a significant influence on participants' emotional intensity ratings in response to the jealousy-provoking videos. Analyses indicated that being short or overweight (in men) and being overweight (in women) were the characteristics that were associated with the greatest decreases in both opposite-sex and same-sex evaluations of attractiveness.

abstract:
There has been a dramatic rise in interest in spirituality over the last decade.
Historically, universities began with a spiritual base. Today, superficially, education
generally appears to have lost its spiritual emphasis. The purpose of this study is to
describe spirituality in Canadian post-secondary education by investigating the work
experiences of 6 professors across 5 different faculties at one university in Ontario.
The intent is to determine the extent of spirituality in these professors’ teaching and to
find out how the professors defined spirituality, and what their viewpoints were with
regard to the barriers and supports to spirituality in education.
This study utilized a mainly phenomenological approach to investigate
spirituality in education. Six participants were chosen and interviewed through a
snowball sampling technique. All of them are male university professors between the
ages of 31 and 60 who come from three religious backgrounds.
Generally following guidelines from Bogdan and Biklen (2003), four themes
emerged from the analysis of the interview data: (a) subjects’ definitions of
spirituality, (b) their perceptions of barriers and supports, (c) benefits, and (d)
application. Through an exploration of the work experience of spirituality in
education, the lived experiences of the researcher and her participants were described
in order to answer the research questions.
The findings from this study could provide educators with first hand accounts
o f how spirituality has been incorporated into the classroom environment within one
Canadian university which could be used as an example to gauge the current situation
o f spirituality education in post-secondary institutions. This study also has the
potential to raise awareness regarding the lack of spirituality in education, and will add to the body of knowledge on spirituality in education, which in turn could
motivate others to investigate the topic further.


title: Relaxation response and quiet resting : are they comparably efficacious in reducing state and trait anxiety? / by Roy F. Thompson.

Relaxation Testing

abstract: Study subjects were psychology undergraduates at Lakehead University, Thunder Bay, Ontario.

abstract:
Anxiety is an essential but occasionally unpleasant emotional state or condition. At its extreme
anxiety can be maladaptive particularly when its level is out ofproportion to a threat, or when it
occurs in the absence ofthreat. Investigators have conceptualized state anxiety as a transient
emotional state, and trait anxiety as a relatively stable individual difference in anxiety-proneness.
While research has suggested that meditation is effective in reducing physiological arousal as well
as state and trait anxiety, some evidence suggests that resting may be the key component of
meditation’s effectiveness. The present study examined the effect ofrelaxation response
meditation and a resting procedure on sfate and trait anxiety. Subjects were randomly assigned to
one ofthree conditions: relaxation response meditation (RR), quiet resting control treatment
(termed “periodic somatic inactivity” or PSI) , or no-treatment waiting list control. It was
hypothesized that, compared with subjects assigned to the waiting list, subjects assigned to the
two treatment conditions would show significant and equal reductions in scores on state and trait
anxiety. Results showed that after 6 weeks only PSI was effective in reducing state anxiety and
that RR and PSI were not effective in reducing trait anxiety.

Continuing education - Social aspects

abstract:
This qualitative study describes the educational experiences of older full-time nontraditional undergraduate students. The participants in this study were over 40 years old and came from varying educational backgrounds. One left high school early while the others had graduated. All had entered the workforce directly from high school, but only one subsequently had attained higher education. None had previously attended university; however, all had degenerative injuries that precipitated a return to school. Questions that explored early school experiences, subsequent learning activities, changing social support mechanisms, and transitional events that affected participants' educational experiences provided a research framework. This study utilized life course and persistence theories to analyze data.  Four main themes emerged: 1) lifelong learning; 2) educational experiences at Lakehead University; 3) adult student identities; and, 4) the impacts of age on nontraditional students.
The research revealed that major life course events, a love of learning and a history of lifelong learning precipitated individual decisions to become full-time undergraduates. Early school experiences profoundly influenced older students’ choices of formal or informal educational pathways leading to full-time university study.  Nontraditional students’ identities reflected complex social and family responsibilities and a focus on higher education providing enhanced economic opportunity. Age had no effect on older students’ cognitive or intellectual abilities, but age did have social
consequence within the university community. All older students felt respected but also experienced ageist behaviours, including, age-based preferential treatment and infantilization.

abstract:
Imprecision and misclassification of land cover types are two issues commonly
encountered in habitat selection studies using satellite land cover classifications and
telemetry data. Here, the utility of broad land cover types is explored in a study of habitat
selection by woodland caribou (Rangifer tarandus caribou). Broad land cover types have
potential to reduce the misclassification error associated with finer land cover types,
while remaining relevant to the factors influencing habitat selection in the species of
interest. Lichen abundance and snow accumulation are two factors important in
explaining the selection of land cover types by woodland caribou in winter, and they are
used here to predict the probability of occupation by caribou of land cover types in three
regions of the boreal forest in Eastern Canada. Land cover types were initially
categorized using Landsat EOSD land cover data, and field surveys were conducted to
measure terrestrial and arboreal lichen abundance in each land cover type. The relative
accumulation of snow was modeled for land cover types using documented patterns of
snow distribution in the boreal forest as well as data collected in the Greater Gros Morne
Ecosystem, Newfoundland, and the Côte-Nord region, Quebec. Subsequently, land cover
types were collapsed into three (dense forest, sparse-open forest, and non forest) that
reflected differences in lichen abundance and snow accumulation while reducing
misclassification errors. Resource selection functions were estimated using logistic
regression where GPS and Argos satellite telemetry data existed for caribou in the
Greater Gros Morne Ecosystem and Middle Ridge regions of Newfoundland and the
Côte-Nord region of Quebec. In all regions, telemetry-monitored caribou selected nonforested areas, where lichen abundance was high and snow accumulation was low, more than expected by chance. The similarities in selection of non-forested areas across
regions despite variation in landscape composition indicates that there are congruencies
both in the factors influencing winter habitat selection and in the relative value of land
cover types on a given landscape. These findings support the argument that resource
selection functions with parameters based on broadly defined land cover types are
applicable among different regions of caribou occurrence and are therefore a valuable
tool for understanding patterns of space use in caribou throughout the boreal forest.


title: The transformative potential of community and collective arts pedagogies in Thunder Bay, Canada

subject: Widening political participation

subject: Critical pedagogies and critical civic praxis

abstract:
This dissertation presents the transformative potential of community art
collectives and outlines the pedagogical practices and decisions that contribute to their
impact in the community. The research took place in Thunder Bay, a small urban
community of roughly 110 000 people in Northwestern Ontario. Building on existing
literature and research on critical civic praxis I explored the relevance of this concept in
collective community arts settings. My research found artists engaged in praxis (the
interplay of critical reflection and practice), their actions informed by an understanding of
systemic oppression affecting their lives as they engaged in re-creating the world in order
to transform it.
This is an arts-informed qualitative research study. Research data includes
interviews with 17 members of the artist community, enriched by my own experiences
with the arts and artist community in Thunder Bay. At the intersection of collective
space, public space, and art I developed an understanding of the relationship between arts
and collective organizing in supporting critical civic praxis as everyday politics. The
transformation discussed by participants is connected to their worldviews and their social,
political, and geographic location. In order to understand this transformative work I have
described the space these artists inhabit, the forms of oppression they encounter, and the
practices that transformed their community. The pedagogical roots that feed participants’
work are authenticity, trust, humility, relationship (love), and critical reflection.

abstract: The purpose of this study was to understand why qualified American and Canadian educators left their home country to teach overseas and more specifically, why they decided to live and work in Kuwait. Fifty-one participants took part in the study. Each was asked to complete a 30 question survey followed by 5 open-ended questions. In addition, demographic information was sought in order to place the data into context. The study followed a conceptual framework adopted from research conducted by Richardson and McKenna (2002) who examined the motivation of expatriates. The findings for this research were placed into context using these terms as the framework from which to operate.  The findings in this study suggest that many of the participants were dissatisfied with their current situation at home, usually job related, and decided to seek opportunities abroad. This dissatisfaction was coupled with the desire to see different parts of the world and to earn a comfortable living. These participants were not interested, for the most part, in advancing their careers or enhancing their skills. They were not interested in providing their services for little or no money. The group of explorers saw an opportunity to earn a tax-free salary, a comprehensive benefit package, and opportunities for travel and adventure. These were the reasons these teachers taught overseas and more specifically, these were the reasons they chose Kuwait.

abstract:
Canada is the current largest supplier of pulp products in China.
However, the current international wood pulp market exists several challenges.
The quantity of exported pulp and pulp production in Canada is represented a
decreasing tendency. On the other hand, China, who is the largest consumer of
wood pulp in the world, still import more and more wood pulp to meet the
domestic demand. Strong competitors such as Brazil, Russia and Indonesia have
their advantages in wood pulp trade with China. Canada can only increase the
wood pulp import by enhance the public awareness, stabilize the monetary
exchange rates, and focus on build a better relationship with Chinese industries.

Intermediate disturbance hypothesis

Structural equation models

abstract:
Disturbance is a potent driver of forests. Components of disturbance such as frequency (i.e., time
since last stand-replacing disturbance) and intensity (e.g., stand-replacing vs. non-stand-replacing
disturbance) plays a major role in influencing plant species diversity. However, majority of
studies often consider the effect of disturbance frequency alone on plant species diversity, few
studies consider interactive effects between disturbance frequency and intensity of disturbance
on plant species diversity. In this dissertation, my first goal was to conduct a meta-analyses to
examine the relationship between overstory tree species diversity and disturbance frequency and
intensity of disturbance. Across tropical and temperate biomes, tree species richness was greatest
at intermediate disturbance frequency with intermediate intensity of disturbance (i.e., non-stand replacing
disturbance).
Furthermore, research on diversity-disturbance relationships (DDRs) often exclude other
critical factors such as climate and local site conditions and thus limit understanding on DDR.
Using observational data from a natural forest in Canada, I examine DDR, under the influences
of climate and local site conditions. I found that the most important factor regulating tree species
diversity was disturbance frequency and local site conditions, indicating that they are important
factors in maintaining biodiversity in the boreal forest landscape.
Empirical evidence often show that wildfire frequency is strongly influence by local site
factors, but broad-scale driver of fires such as climate is rarely considered. I evaluated effects of
local site factors and climate on fire regimes across a large natural boreal forest (about 892,000
ha) with no commercial forest harvesting activity; as such, human influences on wildfire is
relatively little. My results indicated that mean annual temperature and precipitation were the
two most crucial factors driving fire regime in the natural boreal forest studied.
Species diversity has often been linked to temporal stability of ecosystem functions;
however, forest stand development, species composition and soil resource availability may affect
community stability, but these predictors are often overlooked. I investigated whether
community stability (measured as stand level basal area) relates to tree species diversity, forest
stand development, tree species composition and soil resource availability. Temporal stability
was measured as coefficient of variation, which is a principal component of ecosystem stability. I
used repeated measurement plot data from a central boreal forest, which is often associated with
non-stand-replacing disturbances such as spruce budworm and forest tent caterpillar outbreaks,
which selectively kill trees. I highlighted that temporal stability of stand basal area is influenced
by forest stand development and species composition depending on the type of insect outbreak.

abstract: This study investigated the effects of selected pretreatments and rigorous optimization of osmotic dehydration (OD) of lowbush blueberries using Response Surface Methodology (RSM) to produce dehydrated blueberries with high antioxidants content and long shelf life. Fresh wild blueberries (WB) were initially pretreated and then subjected to osmotic dehydration before they were oven dried to the required level (18g/100g of fresh sample). Microwave pretreated WB had shown better moisture loss during osmotic dehydration as compared to other pretreatment methods investigated. The highest levels of phenolics, flavonoids, and anthocyanin content of the dehydrated WB were found to be 742.61 mg/100 g, 263.12 mg/100 g, and 428.11 mg/100 g dry mass respectively, at optimized temperature of 40 °C, for 5 h with 65% (w/w) Brix osmotic solution at 1:5 ratio of sample to Brix%. With rigorous optimization of the critical osmotic dehydration parameters high level of antioxidants could be retained in the dehydrated product. Wild blueberries pretreated in the microwave before osmotic dehydration and oven drying had shorter drying time of 5h compared to the control sample and significantly maintained a higher rehydration ratio (p<0.05) and lower shrinkage ratio compared to the oven dried control. Preliminary mathematical modeling of the process was also carried out to determine the mass transfer coefficients of the system. The results suggest that the drying process developed was a promising alternative method that decreases drying time, achieves high product quality, uses simple process steps for superior drying and retains higher level of antioxidant in the final product.

abstract:
High intensity aerobic-type exercise produces oxygen free radicals that can cause damage
to lipid membranes (lipid peroxidation) that may lead to many problems such as the
inactivation of cell membrane enzymes, the progression of degenerative diseases
(cardiovascular disease and cancer) and lessening of the effectiveness of the immune
system. Little research has examined lipid peroxidation associated with high intensity
resistance exercise, nor the protective effects of antioxidant supplementation.
Additionally training state, which could conceivably affect one’s ability to counter free
radical damage, has not been adequately studied. Fourteen untrained participants and 13
trained participants took part in a double blind, placebo controlled crossover experimental
design study. They received 885 mg tocopherol acetate/day for a 2 week period, received
the placebo during another 2 week period and at the end of each period performed the
Resistance Exercise Test (RET). A 2 group (trained vs untrained) x 2 treatment (vitamin
E vs placebo) x 3 time (pre exercise vs immediate post exercise vs 6 hours post exercise)
factorial ANOVA with repeated measures on time was performed on Malondialdehyde
(MDA) values. There were no significant group or treatment effects found between the 4
groups assessed. There was only one significant difference found and that was in the
main effect for time (F [2,49] = 22.41, p =0.00). This study concluded that the RET
caused a significant increase in MDA in all 4 groups at 6 hours post exercise. There was
no evidence that vitamin E supplementation was effective in reducing oxidative damage
in comparison to the placebo group. As well, there was no difference between the trained
and untrained groups with respect to their impact on lipid peroxidation measures.

title: "Let us all be optimistic from now on" : Oscar Styffe Limited 1927-1945, the middleman of Northwestern Ontario and the pulp and paper trade

subject: Logging Ontario, Northwestern History

abstract:
In the 1930's and 1940's, one way for pulp and paper firms to acquire supplies of
pulpwood from the forests of Northwestern Ontario was through pulpwood dealers or
middlemen. An analysis of one of these timber dealers, Oscar Styffe, and his pulpwood
supply firm, Oscar Styffe Limited, reveals a great deal about the role that the middleman
ofNorthern Ontario played in the pulpwood industry. Research seems to indicate that
operators such as Styffe were quite diverse and to a certain extent flexible within the
industry. This would suggest that they were not totally without control over their own
destinies.


title: Teachers' perspectives on the implementation of the Ontario elementary school science curriculum

subject:

abstract:
This study examined the implementation of the Ontario elementary school Science and
Technology curriculum from the perspective of nine grade 8 teachers of varying experience and
specialization. The questions which this research attempted to address dealt with the teachers’
knowledge of the implementation process and their knowledge of, adaptations to and challenges
with the introduction of the current science curriculum. Included in the study are questions
concerning the changes teachers have made in the means of instruction with specific emphasis on
the inquiry and design method, as well as the changes teachers have made in assessing/evaluating
student achievement.
This research was a preliminary, investigative, applied type research which began when
the implementation process was only in its first year. The qualitative research method of case
study using standardized, open-ended questions was used. Data analysis involved the
organization of the data into categories and subcategories. Inductive analysis was used to
determine themes, patterns and relationships in the data.
Most science teachers have a substantial knowledge of the curriculum (its content and
nature) and feel that in order to cover the extensive, structured, and challenging curriculum they
need to accept it, integrate it, look to each other for support, and re-evaluate continually.
Teachers’ perceptions of their ability to teach science is a major contributor to effective
science curriculum implementation. The majority (six) of the teachers felt that having a science
background (general knowledge of big science ideas) or being qualified in science would assist in
implementation of the new curriculum, and the findings from this study showed that most of the
teachers were knowledgeable about the new curriculum, and were implementing it with little
difficulty.
A major inhibitor to the effective implementation of the science curriculum was lack of
resources: resources to help teachers to implement their lessons, their labs (materials and space),
and their assessments and evaluations. Most teachers’ expectations for the future include more
in-service/PD, teacher resources, equipment, and textbooks.
The factors identified in this study as contributors to or inhibitors of the effective
implementation of the science curriculum included the time intensive and complex nature of the
curriculum, the ability of the teacher to understand and deliver the curriculum with emphasis on
instructional and evaluation practices, and the availability of resources. In addition the assistance
and guidance received from administration and the professional development provided to the
teacher which affects the school culture are also identified as contributors or inhibitors to the
effective implementation of the science curriculum.

Poly-L-glutamic acid

abstract:
Controlled drug release plays an important role in medicine because it can be a factor
in human health care. It is defined as the ability to release a drug inside the body at a specific
time. Radiation-sensitive functionalized materials can be controlled by outside triggers such
as radiation and have great potential for application in controlled and targeted drug delivery.
Radiation-sensitive functional groups are known and studied, however, there are very few
examples. Previous studies have revealed that 2-oxoalkyl group can successfully undergo
radiolytic cleavage, but under relatively high doses of radiation. It is desirable that the
radiolysis efficiency of 2-oxoalkyl group be improved in order to gain applications in clinical
medicine. Thus, one objective of this thesis was to study the effect of a few substituents on the
radiolysis efficiency of substituted 2-oxoalkyl groups. Therefore, a few molecular probes that
contain an aryl 2-oxoalkyl group with substituted acetophenone of monoesters of adipic acid,
and coumarin scaffold of monoesters of adipic acid have been successfully synthesized.
These compounds were studied under X-ray radiation at various doses to assess the potential
of selective cleavage of the aryl oxo-methyl ester linkage. The radiolysis studies showed that
less than 10% of the ester linkages in these compounds were degraded under a dose of up to
20 Gy of radiation. Compounds were also studied for their hydrolytic rate for the aryl oxomethyl
ester linkage using TLC method. Hydrolysis at around neutral pH happened at a slower
rate for compounds that are sterically more hindered at the oxo-methyl position.
Poly-L-glutamic acid (PGA) is a natural polypeptide that is biodegradable and
biocompatible. Therefore, it has been exploited as drug carrier system. In this thesis, PGA has
been modified with a phenacyl group. The lipophilic phenacyl group is assumed to assist the
formation of nanoparticles for the modified PGA. Radiolysis studies of such modified PGA
showed that the grafted phenacyl group can be selectively cleaved upon radiation with a
clinically relevant dose.
Lawsone is a commercially available natural product. It has been used as starting
material for the synthesis of different biologically active compounds. Lawsone also has various
biological effects including anticancer activity. One anticancer mechanism of lawsone is
associated with its ability to undergo one-electron reduction. Thus, another aspect of this
thesis was to synthesize lawsone derivatives as potential anticancer agents. The preparation
of glycosylated lawsone derivatives was of particularly interest. Direct glycosylation of lawsone
using a number of methods was unsuccessful in providing fully deprotected lawsone
glycosides. Then the Mannich reaction was employed to produce a group of lawsone
derivatives including one compound bearing a glucose residue. The synthesized lawsone
derivatives will be evaluated for anticancer activity in the future work.

abstract:
Cytological studies revealed irregularities in the nuclear life
cycle of Inonotus tomentosus. The mycelia was multinucleate and the
nuclei were found in groups of two to six. By the time the nuclei
reached the subhymenium most of the cells were binucleate.
Chlamydospores were multinucleate and most freshly shed basidiospores
were uninucleate. The orientation of meiotic division in basidia was
oblique. Spindle pole bodies (SPBs) were observed but microtubules
were absent. Postmeiotic mitosis occurred sometimes in basidia and
sometimes in basidiospores. Binucleate spores were occasionally
observed.
The DNA specific dye, 4'-6-diamidino'-2-phenylindole (DAPI), was
used in this study. In some hyphal cells, germ tubes, and
chlamydospores, DAPI-positive particles (DPPs) were observed. The DPPs
showed mostly a yellow fluorescent color. Similar observations of
nuclear-like material were made with associated bacteria. The DNA
material may be viruses or plasmids. Ultrastructural studies revealed
some possible bacterial-like structures and mycoplasma-like organisms
in hyphae and chlamydospores. The nature and function of DPPs were
discussed.


title: Physical activity promotion in Sudbury-area call centres : employers' perspectives / by Sheila Joan Renton.

subject: Work environment

subject: Call centre employees - Physical activity

subject: Call center agents - Physical activity

subject: Sudbury region (Ontario)

abstract:
A 2004 report from the Ontario Chief Medical Officer of Health identified the workplace as a key setting for the implementation of strategies for the promotion of physical activity as part of a plan to help Ontarians achieve and maintain healthy weights (Chief Medical Officer of Health (Ontario), 2004). A concurrent, embedded mixed methods design was used to explore the responses of call centres employers within the City of Greater Sudbury to the Chief Medical Officer of Health’s recommendations, to develop an understanding of current practices in call centre workplaces that support physical activity, and to investigate employers’ motivation to implement
physical activity promotion, as well as perceived facilitators and barriers.
Face-to-face, semi-structured interviews and quantitative questionnaires were completed between February and July 2009 with fifteen managers in ten of the twelve call centres identified by the Growth and Development Department of the City of Greater Sudbury.
Results provided insight into the employers’ motivation to implement physical activity promotion initiatives as they relate to three particular themes: The Employer Reaps the Benefits, Concern for Employee Well-being, and a sense of The Greater Good. Several internal and external
facilitators for the promotion of physical activity were identified. Factors which create barriers to physical activity promotion within call centres were described by three themes: The Nature of Call Centre Work, Concerns of Managers, and Characteristics o f the Call Centre.
This study extends the research knowledge on the topic of physical activity promotion within call centres and leads to six recommendations for action at local and provincial levels which are expected to promote the health of call centre employees, and possibly other Ontario workers.

Denitrification/nitrification processes
Plant assimilation of nitrogen

abstract:
This thesis summarizes the usage of constructed wetlands in reducing nitrogen
loaded anthropogenic waste water, sourcing a collection of results of outside literature.
The literature used in this thesis was found from scholarly websites. The purpose of this
study was to determine the most efficiently constructed wetland design in terms of its
nitrogen content removal, and to provide further insight into the new constructed
wetland technology. In this study the term efficiency is based on the nitrogen removal
rate determined by each data variable. Wetland type / design and removal mechanism
were the attribute data collected and examined, all of which was found in the results of
prior literature. The two removal mechanisms used were denitrification / nitrification
and plant assimilation. The two-wetland types used in this study were surface flow
constructed wetlands and subsurface flow constructed wetlands. A one – way ANOVA
was completed to determine the significant difference in nitrogen between the two
removal mechanisms, as well as the significant difference between the two wetland
designs. It was determined that there is no significant difference in nitrogen removal
between the removal types and wetland designs. Insight and comparison with each
constructed wetland study were allowed for the results to be accepted. Two scientific
rationalizations were discussed to further accept the results found. These rationalizations
included the overall performance of nitrogen removal and the secondary variables
related to the wetland design. It was concluded that further research is needed to further
comprehend this constructed wetland technology.


title: Dynamic stability of axially loaded beams on elastic foundations

subject:
Dynamic stability
Pipes matrix method
Beams on elastic foundations
Stress waves
Rock slope (stability)

abstract:
Beams on elastic foundations have received great attention of researchers for its
importance in civil engineering. The present work can be applied, for example,
to the study of dynamically loaded finite columns which are embedded in soil
and supported by a layer of bedrock, or to the dynamic buckling analysis of
longitudinal fibers in a composite elastomer.
The dynamic stability of simply supported beam-column under periodic axial
loading, and laterally resting on an elastic foundation is investigated. The combined
effect of stiffness and damping is exerted on the beam through the foundation.
Traditionally, the periodical sinusoidal waveforms have been considered as the
axial dynamic loading. However, in practical engineering, dynamic loading may
exhibit other waveforms. Therefore this thesis considers various periodical waveforms
as excitations in the derivation of the dynamic stability.
The equation of motion for the system is derived. This equation is further processed
and transformed into the Hill equation. The conditions for dynamic stability
regions are developed using Pipes matrix method for periodical loadings. The
theoretical solutions are provided for various waveforms such as rectangular loading,
sawtooth loading, exponential loading and sum of the step loading. In order
to conduct numerical simulations and to develop the diagram for dynamic stability
region, certain reasonable assumed values are taken for mechanical property
of beam and various parameters.
Using dynamic stability plots, effects of various parameters such as flexural stiffness
of beam, damping, and stiffness of foundations are studied and discussed on
dynamic stability of a beam. Moreover, the first three vibration modes of beam
modal analysis are conducted. In order to evaluate the accuracy of the solutions,
a comparison is made among the solutions obtained from Pipes matrix method,
Floquet theory, and finite element method.
As an example of applications, the study of buckling of rock slope resting on
the elastic foundation is carried out and is modeled for blasting vibrations. In
addition to that, the factors affecting the buckling of rock slope with blasting
are also discussed. The dynamic stability solutions for arbitrary loadings are
illustrated using wind sampling data which is obtained.

title: Cross-talk of hydrogen sulfide and nitric oxide in vascular endothelial cells

contributor:

Yang, Guangdong

subject:
Vascular endothelial cells
Hydrogen sulphide
Nitric oxide

abstract:
Gasotransmitters, like hydrogen sulfide (H2S) and nitric oxide (NO), are small gaseous molecules that can be generated in different types of mammalian cells by enzymatic catalyzation.  Cystathionine y-lyase (CSE) and endothelial NO synthase (eNOS) are responsible for the
majority of endogenous production of H2S and NO in vascular endothelium, respectively. H2S and NO maintain different vascular functions. Here we show that H2S interacts with eNOS to increase NO release from endothelial cells (ECs). Two mechanisms are involved in this
interaction. Firstly, H2S indirectly induces eNOS phosphorylation. Secondly, H2S directly modifies one cysteine residue of eNOS through S-sulfhydration. Stimulation of eNOS phosphorylation and S-sulfhydration by H2S subsequently increases NO release. The
phosphorylation of eNOS by H2S is p38 and Akt-dependent. eNOS S-sulfhydration is partially affected by S-nitrosylation but not by phosphorylation. We further found that knockdown of CSE
gene by siRNA technique, or blockage of CSE enzyme activity by PPG (dl-propargylglycine),  attenuates NO production. CSE overexpression or L-cysteine (a substrate of H2S) supplementation stimulates NO production.
The level of eNOS S-sulfhydration in aortic tissue from CSE knockout (CSE-KO) mice was lower than that from wild type (WT) mice. L-cysteine treatment increases S-sulfhydration of eNOS in ECs isolated from WT mice, but not in ECs isolated from CSE-KO mice. GSNO (a NO
donor) induces, but NaHS reduces, eNOS S-nitrosylation. However, GSNO does not alter eNOS S-sulfhydration whereas NaHS alters S-nitrosylation. Site-directed mutagenesis of one cysteine
residue Cys-443 in eNOS (Cys-443-eNOS) completely eliminates eNOS S-sulfhydration and partially decreases eNOS S-nitrosylation. Although the mutation of serine 1179 (Ser-1179)  completely abolishes eNOS phosphorylation, it does not affect eNOS S-sulfhydration. The
dominant configuration of vascular eNOS proteins purified from WT mice is dimer, whereas in CSE-KO mice it is monomer. In the presence of GSNO, more monomers are found with WTeNOS, which is reversed by a subsequent treatment with NaHS. Cys-443-eNOS manifests itself
as monomers, which is not changed by either GSNO or NaHS treatments. The production of NO is decreased but superoxide is increased in CSE-KO ECs in comparison with WT ECs.
H2S treatment increases EC proliferation, tube formation, angiogenesis, and accelerates wound healing. With an in vitro aortic ring angiogenesis assay, we found a reduction in the number of microvessels formed by culturing aortic rings from CSE-KO mice, even in the
presence of VEGF (vascular endothelial growth factor). We further found that wound healing is faster in WT mice when compared with CSE-KO mice, and H2S promotes wound healing recovery. Blockade of NO production by eNOS-specific siRNA or L-NAME (L-NGnitroarginine
methyl ester) reverses, but eNOS overexpression potentiates the proliferative effect of H2S. In contrast, CSE knockdown attenuates the pro-proliferative effect of NO.
Overall, our studies demonstrate that H2S increases NO release in ECs through phosphorylation and S-sulfliydration of eNOS. Thus, H2S and NO are required for the physiological control of angiogenesis and superoxide production. Mechanistic understanding of H2S-NO interaction in vascular endothelium will help advance novel therapeutic strategies for
EC dysfunction related vascular diseases.

Long-term over-cutting

abstract: In the last century, China chose a planned economic system and formulated a strategy for the development of heavy industry. The chosen strategy for heavy industry has given forestry a half-century task, both to provide capital for industrial development, and to provide a sustainable supply of timber for this industrial development, and to provide a sustainable supply of timber for this industrial development. Long-term over-cutting has exhausted the forest resources in much of China. Conflicts between economic, ecological and social objectives were acute. After 50 years of over-cutting, the economic, ecological and social objectives were not being satisfied. To solve these problems, China implemented the Natural Forest Protection Project (NFPP). NFPP focuses on the work of state-owned forests previously used for timber production.

abstract:
This mixed-method study examined the perceptions of preservice teachers about
teaching in Northwestern Ontario, and how these perceptions influence their decisions to
apply for teaching positions within the area through the use of a longitudinal survey
design. The purpose for this study was to explore what factors preservice teachers
utilized when deciding where to apply for teaching positions, and what the government,
universities, and school boards can do to attract teachers to Northern schools. The
sample population ^=57) included 46 females and 11 males. 60% of the sample
population had never lived in a rural community; 61% had never lived in a northern
community; and 84% have never lived in an Aboriginal community. The present study
found that, while many preservice teachers found Thunder Bay an enjoyable city in
which to live, they felt unprepared to teach in Northern communities. The study also
indicated that participants felt that there was too much emphasis on Aboriginal
Education, to the detriment of multicultural education, as many of them planned to return
to their homes in Southern Ontario. The present study found that university courses had
serious implications for students' decisions to teach in particular areas. Students
developed schemata based on familiar stories, and the attitudes of professors, whether
they spoke negatively or positively about teaching in Northern communities.

subject: Sedimentary depositional environment

abstract:
The Quetico metasedimentary subprovince and the volcanic-plutonic
Shebandowan belt to the south meet along an east-west
steeply dipping boundary that is believed to have been affected
by dextral transpressional deformation. It is also parallel to a
steep metamorphic gradient from greenschist facies rocks to the
north.
Macroscopic petrofabrlcs are difficult to observe along
the belt to the west of Thunder Bay but magnetic susceptibility
fabrics (low-field) are quite consistent. These define a gently
plunging extenslonal fabric parallel to the belt boundary.
Within the Kashabowle area, general field observations of
subhorizontal stretching (and intersection) lineations, and
cleavage directions are in agreement with magnetic susceptibility
axis directions. Mineral separation reveals that all samples
have multiple sources of magnetic susceptibility, dominated by
metamorphic phyllosilicates. Consequently it is not possible to
simply quantitatively relate the magnetic fabrics to strain
magnitudes although the magnetic fabrics accurately monitor
significant kinematic directions. Analyses of strain of
low-grade detrital quartz grains, magnetic fabrics and general
field observations recognize flattened oblate fabrics. Moreover
oblique, subhorizontal lineations favour a transpresslve
kinematic model with compression normal to the belt boundary.
The obliquity between mineral and magnetic lineations seem to
indicate dextral transpresslve deformation.

abstract: The research presented in this thesis is on the development of a trace gas detection system based on intracavity absorption spectroscopy (ICAS). The developed system was capable of detecting nitrous oxide (N2O) and acetylene (C2H2) gas at sub-ppmv levels. The P (12) rotational line of N2O at ~1522.20 nm, and the R (5) and R (4) rotational lines of C2H2 at ~1522.22 nm were used for detection. A fiber Bragg grating was incorporated into the ICAS cavity to enhance the system sensitivity by allowing the selection of strong absorption lines for detection. By operating the fiber laser based ICAS system at threshold, multiple circulations of the amplified spontaneous emission inside the cavity enhanced the system detection sensitivity. Further, the laser wavelength contained multi-longitudinal modes, which improved the system sensitivity. The system sensitivity was explored for two intra-cavity gas cells: a multi-pass Herriott cell and a gas cell based on a hollow-core photonic crystal fiber (HC-PCF). The system operated at room temperature and a polarization-maintaining erbium-doped fiber was used as a saturable absorber to help eliminate mode hopping in the laser cavity.

abstract:
This study examined the effects of making explicit the performance expectancy component of
teaching and learning for Grade 8 science students. The performance expectancy used in this
research specifically focused on students’ predictions of their level of performance on science
tests, also referred to as “expectancy statements”. This study focused on the following questions:
1. Which variables (predicted score, study time, test rating) best predict student scores?
2. Does the accuracy (the closeness of the student’s predicted score to his/her actual
score) of students’ expectancy statements change with practice?
3. Do students think the use of expectancy statements is helpful in improving their
scores?
4. Do students think that the expectancy statements become more accurate with
practice?
5. Do students think that their study habits change through the use of expectancy
statements?
The data for this study were collected through student classroom files and surveys, and
analyzed quantitatively and qualitatively according to the five research questions. The process of
quantitative data analysis involved the use of descriptive statistics, ANOVA, and stepwise
multiple regression analysis. Qualitatively the data were organized according to recurrent themes.
From this study’s findings, it appears that performance expectancy fostered intrinsic
motivation, in the form of students’ perceptions of improvements in study habits and increased
confidence levels. Statistically the relationship between expectancy statements and test scores
was positive yet weak.

title: A Novel DTFC Based Efficiency and Dynamic Performance Improvement of IPMSM Drive

subject:
Permanent magnet synchronous motor
Field oriented vector control
Direct torque and flux control
Voltage source inverter
Nonlinear controller

abstract: With the advancements in magnetic materials and semiconductor technology, permanent magnet synchronous motor (PMSM) is becoming more and more popular in high power industrial applications due to its high energy density, high power factor, low noise and high efficiency as compared to conventional AC motors. Field oriented vector control (VC) and direct torque and flux control (DTFC) are used for high performance drives. Among these two techniques DTFC is faster and simpler than that of conventional VC scheme as DTFC scheme doesn’t need any coordinate transformation, pulse width modulation and current regulators. The DTFC based motor drives utilizes hysteresis band comparators for both torque and flux controls. Both torque and flux are controlled simultaneously by the selection of appropriate voltage vectors from the inverter. However, DTFC suffers from high torque ripples due to discrete nature of control system and limited voltage vectors from the inverter. Torque ripples can be minimized by increasing the sector numbers of the DTFC scheme which increases the switching frequency of the inverter. Traditionally, researchers chose a constant value of reference air-gap flux to make the control task easy but it is not acceptable for high performance drives as the air-gap flux changes with the operating conditions and system disturbances. Furthermore, if the reference air-gap flux is maintained constant, it is not possible to control the motor over the wide speed range operation. Moreover, conventional six-sector based DTFC scheme suffers from high torque ripples, which is the major drawbacks to achieve high dynamic performance. Therefore, this thesis presents a novel eighteen-sector based DTFC scheme to achieve high dynamic performance with minimum torque ripples. In addition, the loss minimization algorithm (LMA) is incorporated with proposed DTFC scheme in order to improve the efficiency while maintaining high dynamic performance. This thesis further presents modified eighteen-sector based DTFC scheme to overcome the unbalanced voltage effects in any sector of conventional six-sector based system to improve the dynamic performance of the proposed system. This thesis also presents a novel sector determination algorithm to determine the sector number of the stator flux linkage vector which reduces the computational burden to the microprocessor. A five level torque hysteresis comparator based DTFC scheme is also proposed to reduce the torque ripple. Further, a backstepping based nonlinear controller is developed for IPMSM drive that achieves the lowest possible torque ripples in steady state. In this controller development, the control variable is motor electromagnetic developed torque and stator air-gap flux linkages similar to classical DTFC but the errors are forced to zero using backstepping process to get better dynamic performance. The effectiveness of the proposed systems is verified through the development of a simulation model using Matlab/Simulink. Performance of the proposed nonlinear controller is investigated extensively at different operating conditions such as sudden speed and load changes. Then the complete IPMSM drives, incorporating the proposed LMA and eighteen-sector based DTFC scheme and nonlinear controller with torque and flux as virtual control variables are successfully implemented in real-time using digital signal processor (DSP) board-DS1104 board for laboratory 5-hp motor. The effectiveness of the proposed control techniques are verified in both simulation and experiment at different operating conditions. It is found that, the nonlinear controller based IPMSM drive provides the best performance in terms of torque ripple among all the DTFC scheme developed in the thesis. The results show the robustness of the drive and it’s potentiality to apply for real-time industrial drive applications.

abstract:
This study was done to test the ability for Unmanned Aerial System (UAV) equipped with thermal imagery cameras to detect thermal decay of footprints within the snow left by people, in hopes to apply thermal imagery and drones into wildlife surveying. The UAV DGI Inspire that was used and had a colour visual (RGB) ZENMUSE camera attached with an electronically stabilizing gimbal and the FLIR Vue Pro camera which is able to record and take images in thermal. The scope of the trial was for students to walk into a snow-covered McClusky airfield, fly multiple flights after and during the time that the tracks were being left and to analyze the images.
It was found that the pixel resolution and quality of the FLIR Vue Pro camera was not able to detect footprints left within the airfield. It is suggested to fly in a better suited area at colder temperatures and deeper snow, use a higher quality of camera, and fly at a lower altitude in future hopes of applying thermal imagery to detection of wildlife and their tracks.

abstract:
During the 1970s and into the 1980s the communications media and
educational theorists have reported and analyzed public dissatisfaction with
school systems. One cause of this dissatisfaction is that school systems have
become isolated from other institutions, such as the home, the church, and
the media, which participate in the education of children (Goodlad,1984).
Involving the home in the formal educational process could form a link
between home and the school and, indeed, may be necessary to the survival
of public education (Goodlad,1984).
The education of a child begins at home before he enters school and
continues there throughout the school years. Acknowledging the value of
and making use of the home educational process can greatly enhance the
total educational experience of the child. Involving the home in classroom
programs can promote better understanding between home and school and
a positive public perception of educational systems. This study focuses on
linking home and school. It investigates teachers' use of and attitudes to
home instruction which is coordinated with the classroom program, and the
attitudes of parents toward this practice.

abstract:
Three experiments were conducted to Investigate the
generality of the guidance hypothesis to a brief practice
(acquisition) session. Three research paradigms were
studied consistent with those outlined by Schmidt (in
press). Schmidt has been vocal in advocating the notion
that frequent knowledge of results (KR) degrades learning.
In experiment 1 the relative frequency of KR was
investigated by employing four frequency conditions with a
5-trial acquisition phase. Summary-KR was studied in
Experiment 2, utilizing three different summary lengths with
a 15-trial acquisition phase. Finally, the trials-delay
procedure was considered in Experiment 3. There were four
varieties of delay, each having a total of five KR
statements. In all three experiments the task involved a
limb movement from left key to right key, performed in a
criterion time of 500 milliseconds. All three experiments
employed an immediate retention test (10 minutes later) and
a delayed retention test (2 days later) to determine if the
experimental conditions affected learning.

abstract: This study described the experiences of volunteer minor hockey coaches (VMHC), program organizers program facilitators (the participants) in a web-based, facilitated coach education program (CEP) called Play It Cool (PIC). Fifteen VMHCs participated in weekly, structured lessons on safe and effective ice hockey coaching that were delivered asynchronously using streaming content. VMHCs were requested to apply lesson content (i.e., seven modules) with their teams and report back on the website discussion forum. This forum was intended to promote weekly collaboration between VMHCs and interaction with an on-line expert facilitator. PIC offered an alternative to traditional formal CEP (i.e., National Coach Certification Program in Canada) which are typically classroom-based, weekend seminars that are reportedly not well attended (Misener & Danylchuk, 2009). Various studies report perceived benefits resulting from trained and educated coaches but that coaches tend to prefer informal methods of learning how to coach (e.g., mentorship, personal playing experience) (Bloom, 2002; Gilbert & Trudel, 1991; Vargas-Tonsing, 2007). A qualitative case study methodology using thematic data coding (i.e., data sources included discussion board postings and related e-mail)was employed to describe the experiences of the PIC participants PIC. Fifteen participants, mostly middle-aged males (n=14) with limited formal coaching education and minimal amounts of playing and coaching involvement, left evidence over prescribed eight week periods.

abstract:
Prior research has suggested that feminist therapy is an effective form of counseling for
battered women (BW). To date however, virtually no studies have considered the importance of
the client's expectations of, or preferences for feminist therapy over other types of therapy. In the
present study, 20 battered and 20 nonbattered women (NBW) each read transcripts of three
different types of therapy: nonsexist cognitive (CT), liberal feminist (LFT), and radical feminist
(RFT). The order of presentation was counterbalanced. The women were measured on general
therapy preferences for: Counselor Attitudes and Behaviors (P-CAB), Counselor Characteristics
(P-CC), Counseling Process and Outcome (P-CPO). In addition, their expectations about each of
the three therapists were measured on the following scales: Counselor Attitudes and Behaviors
(E-CAB), Counselor Characteristics (E-CC), and Counseling Process and Outcome (E-CPO),
Perceived Helpfulness (PH) of the therapist, and Willingness to See (WS) the therapist. Results
indicated that BW and NBW did not differ significantly on any of these scales. However, both
BW and NBW expected the RFT to show significantly more of the counselor attitudes and
behaviors (i.e., acceptance, confrontation, directiveness, empathy, genuineness, nurturance, and
self-disclosure) presented than the CT. In contrast, they expected the CT to possess more of the
counselor characteristics (i.e., attractiveness, expertise, tolerance, and trustworthiness) than the
RFT. Finally, they expected a more positive counseling process and outcome (i.e.. concreteness,
immediacy, and outcome) with the CT than with the RFT. Expectations about the LFT did not
differ significantly from either expectations about the CT or the RFT on these scales. All three
therapists were perceived as equally helpful, and the women were equally willing to see each of
them. However, the majority (66%) of both BW and NBW chose the CT as their favorite
therapist. The research and clinical implications of the findings are discussed.


title: Opportunities for character development in multi-cultural settings

contributor:
Melville, Wayne

Xu, Shijing

abstract: This dissertation explores character development opportunities in for first-generation Nepali immigrant students, as exemplified in Ontario public school classrooms. The theoretical framework for this dissertation is derived from Aoki’s conceptualisation of the ‘in-between,’ which relates to the experiences of people living in the binaries of East and West, communitarian/liberal, and home- and host-cultures. Metaphorically, this dissertation understands character development to occur in the negotiations that people engage in on the central portion of a “bridge” between the binaries. Written and interview data was collected from three Nepali students, representing the home-culture, and the three teachers representing the host-culture. This data was then developed into a series of Vignettes that were then analysed, following the strategy of interpretive phenomenological analysis. The discussion of the themes, which emerged from the analyses of the Vignettes, has been made using the trope of the bridge, explaining that the distant ends of the bridge are symbolic of the binaries in which people live. Ontario public school classrooms are the inclusive spaces of the ‘in-between,’ where people from both the ends of the bridge hold prolonged communications and use the language of virtues. The analysis shows a strong link between the lived experience of the participants and the Ontario Ministry of Education character development document. The discussion reveals that character development is the negotiation in the ‘in-between’ of the bridge. This dissertation concludes with implications for the credibility of the Ministry character development document, the importance of engaging in purposeful communications, and using the language of virtues in negotiations between the values of home- and host-cultures.

abstract:
Age-related macular degeneration (AMD) is a progressive eye disease that affects
the macula, causing blurred central vision making it difficult for diagnosed patients to
see fine details and have trouble with everyday tasks. Recent studies have suggested
that blue light is able to cause damage to eyes that progresses to AMD. Exposure of blue
light to our eyes is a growing concern in our everyday lives due to the prevalence of
computers, phones, and tablets. Blue light is responsible for cell damage, cell death, and
oxidative stress, all of which can lead to vision loss. Resveratrol and pterostilbene are
polyphenols found in the skin of various fruits including grapes and blueberries and
have been well studied for their antioxidant properties. The aim of this study was to
investigate the biological activity of resveratrol and pterostilbene on cell viability (MTS
assay), cell death markers (Caspase-3/7 activity, Caspase-3 protein expression and
Propidium Iodide assay), antioxidant potential (catalase and MnSOD), and the levels of
oxidative stress (4HNE), in retinal pigment ARPE-19 cells exposed to blue light. ARPE19 cells were incubated with a pre-treatment of 50µM and 100µM of resveratrol or
10µM and 250µM of pterostilbene for 4 hours followed by the exposure of blue light
(475nm) for 12 hours. Blue light exposure on ARPE-19 cells resulted in a 56% reduction
(p<0.0001) in cell viability along with an increase in caspase 3/7 activation, and a 50%
increase (p<0.0001) in cell necrosis. This was accompanied by an increase in protein
adduct formation of 4HNE and protein expression of antioxidants such as, catalase, and MnSOD. Resveratrol treatment of 50µM was able to maintain cell viability by 37%
(p<0.05), and significantly (p<0.05) reduced the caspase 3/7 fluorescence activity when
compared to control cells exposed to blue light. Cellular necrosis was also significantly
reduced (p<0.05) by both 50µM and 100µM treatments of resveratrol. In conclusion, the
damaging effects of blue light was mitigated by treatments of resveratrol in ARPE-19
cells. Pterostilbene treatments of 10 and 25µM were unable to maintain cellular viability
across both MTS assay and caspase 3/7 fluorescence assay. Both concentrations showed
opposite results when compared to the 50 and 100µM treatments of resveratrol.


title: Image, symbol, and the life of the imaginaton in the works of Sinclair Ross

abstract:
Until very recently, studies of the works of Sinclair
Ross have over-looked his literary artistry to focus on his
place among those writers whose time and place is the
Canadian prairie during the Depression, Ross’s importance
as a literary artist goes beyond this restricted time period.
His imagery and symbolism explicate a view of life which is
timeless. This thesis examines, in particular, the imagery
and symbolism of the horse and the wind as representative of
the polarized but co-existing elements of benevolence and
destruction in the world. In chapter one—a discussion of
Ross’s short stories about childhood—the horse, as symbol
of the creative, benevolent side of life, dominates. The
wind, symbol of destruction and malevolence, dominates the
lives of Ross’s adult characters, as shown in chapter two.
However, neither symbol can exist exclusive of the other. As
a result, the duality of Ross’s vision of life is shov/n more
fully by the interplay of the horse and wind symbols in the
novels discussed in chapter three. This study concludes with
an examination of the horse and wind symbolism in Ross’s final
novel which re-inforces and solidifies his view of the human
condition into a single image illustrating the co-existence
of the benevolent and malevolent elements of life.


title: Evaluation of natural regeneration potential of a degraded forest in Ghana

subject: Forest regeneration Ghana

subject: Reforestation Ghana

subject: Natural regeneration of tropical forests

subject: Restoration of degraded forests

subject: Seedling growth

subject: Silviculture

abstract:
Vast areas of forests have been degraded in Ghana. The degraded areas are generally
invaded by Chromolaena odorata, a strong competing species for trees. Planting is the
major primary means that is currently used to restore these areas back to forests.
However, natural regeneration or human-assisted natural regeneration may provide an
alternative way to regenerate these areas. To evaluate the potential of this alternative, the
density and species composition of tree seedlings under the canopy of Chromolaena
odorata and the seeds of both trees and Chromolaena odorata in a degraded area were
estimated. The response of tree seedlings to the removal of Chromolaena odorata was
also examined. One hundred and eight plots were established 20 m apart for assessing
the tree seedlings. Chromolaena odorata was removed from SO % of the plots to release
tree seedlings and left the other half intact. Seedling height, the number of leaves per
seedling, and seedling mortality were assessed in both released and unreleased plots
immediately after the release treatment (June 1998) and again three months later
(September 1998). Smaller plots (0.2S m2) next to half of the seedling plots were used to
sample the soil seed bank. The soil samples were taken from two different depths and
germinated in a germination house. Fifty five species of tree seedlings and seven species
of tree seeds were found at the site. There were 11,780 seedlings ha-1 and the seedlings
were well distributed in the degraded area. The density of tree seeds (46,000 seeds ha-1)
was 3.8 times higher than tree seedlings, but the species composition o f tree seedlings
was 7.8 times higher than the species composition of seeds. The spatial distribution of
tree seedlings was more even than that of tree seeds. The tree seed density did not vary
significantly with soil depth but the seed density of Chromolaena odorata (73.89 million
seeds ha*1) decreased with increasing depth from the surface. There were 1,606 times
more Chromolaena odorata seeds in the soil seed bank than tree seeds. Tree seedlings
responded positively to the removal of Chromolaena odorata. The height increment and
the increase in number of leaves per seedling were three times greater in released
seedlings than the unreleased ones three months after the release treatment. Sixty four
percent o f the species suffered various levels of mortality in the unreleased plots, but all
the seedlings of all the species survived in the released plots. The results suggest that
there are enough tree seeds and tree seedlings to restore the degraded area back to forest.
However, tree seedlings will have to be released from the competition of Chromolaena
odorata.

abstract:
The study tested the effects of video replays enhanced with graphic, kinematic feedback on a targeted aspect of the hockey skating stride. A single subject, multiple baseline, across participants design was used. Participants were 4 varsity hockey players. Feedback was a measurement of the supporting knee angle at extension of the thrusting leg and a visual
representation of an optimal angle, superimposed over video replay. Feedback immediately followed alternate trials, during several sessions over 5 weeks. The targeted change was a lower angle of initial knee flexion. Mean and level of initial knee flexion reduced after intervention in all participants. Changes were observed to occur at the second session of the intervention phase.


title: Study of the social factors contributing to youth smoking in an Inuit community / by Michelle, Doucette.

subject:
Inuit youth - Tobacco use
Smoking - Inuit youth
Northern Canada

abstract:
Inuit people in the Canadian Arctic have the highest rates of tobacco use of any population in Canada. On average, 70% of Inuit people use tobacco (Godel, 2006; Health Canada, 2005b; Ritchie & Reading 2003). This study investigated tobacco use among Inuit youth. Using a mixed methodology the researcher facilitated the input of a community focus group to direct the study and provide input into the editing of the survey instrument. The focus group adapted a previously existing survey from a study done with Aboriginal youth to make it appropriate for an exclusively Inuit population. The survey questioned the social influences that encouraged youth to begin smoking or to abstain from tobacco use. The study found significant statistical relationships between smoking caregivers and youth smoking as well as low self-reported health status and smoking. The study also found that youth who had a boyfriend or girlfriend had a statistically significant chance of not being a smoker. The results suggest that personal relationships are the most important predictors of smoking status for
Inuit youth.
The author suggests that future research needs to consider the importance of personal relationships in investigating reasons for smoking and in planning health education and tobacco cessation programs.

abstract:
Depression is a serious mental health disorder, with enormous costs to individuals and society. According to the 2012 Canadian Community Health Survey, approximately 1.9 million Canadians have reported a major depressive episode within the last twelve months.1 While alarming, this figure does not capture the level of subclinical depression (or depressive symptomatology) in the Canadian population. Some estimates have suggested that the prevalence of subclinical depression is much higher, at 22%. 2 Hence, factors that mediate or prevent the development of subclinical depression are of interest. Music therapy has been shown to reduce feelings of depression in elderly patients, but it is unclear what the effect of playing music as a hobby may have on the development of depression. 3-11
Some research has suggested that musicians may suffer from a disproportionate amount of mental health disorders when compared to their non-musical counterparts. 12-14 Music is frequently used as a way to reduce stress, and it is possible that individuals with serious mental health disorders (MHD) turn to music as a means of escape. 15-17 While several studies have suggested that professional musicians have higher levels of depression than their non-musical counterparts, this research has been conducted in musical professionals alone. 12-14 No study has evaluated the potential relationship between playing music as a hobby and the development of subclinical depression in university students. Based on studies regarding music therapy, it is highly plausible that music may offer a significant means by which to reduce the presence of depressive symptomatology. Further study on the impact of musicianship on the development of mood disorders is warranted.
A cross-sectional survey was used to pose questions to a group of university students regarding their experience playing a musical instrument over their lifetime and depressive symptomatology. Within the musician cohort, a further investigation was conducted into the relationship between improvisational ability and presence of mental health disorders. Additional information regarding potential confounding variables was also captured in the survey. Music has been shown to possess therapeutic qualities in certain demographics, but its association with depressive symptoms in average university students is unknown. 3-11, 18-21 Exploring this association will help to direct larger studies, and will allow us to hypothesize potential roles of music in relation to subclinical depression.
Short-term mood-boosting effects of music have been widely reported in the literature; however, these findings are often studied in a therapeutic context, and not treated as a lifelong exposure.3-11, 18-21 This study is the first of its kind to employ a cross-sectional survey to ascertain different levels of musical exposure, as well as the musician’s improvisatory capabilities. This study attempts to take a sample of average Canadian students and explore the potential relationship between lifelong music exposure and depressive symptomology.

abstract:
The effect of large scale exploitation of walleye Stizostedion vitreum
vitreum on the boreal percid community of Henderson Lake, northwestern
Ontario, was studied from 1979 to 1981. Investigations centered on the two
major predators in the community, the walleye and the northern pike Esox
lucius. Population estimates were done in 1979, 1980 and 1981, and the accuracy of Schnabel, Schumacher Eschmeyer and Peterson estimates were compared.
Previous to exploitation (1979-1980) both walleye and northern pike exhibited the lowest production and P/—B ratios yet recorded for either species (walleye 4-14 yrs, P=1.01 kgha[superscript -1] yr[superscript -1], P/B =0.137; northern pike 7-14 yrs, P=0.716 kgha[superscript -1] yr[superscript -1] , P/—B =0.086). Low production in both species was partially attributed to competition for major prey species, and the small size
of available prey items. Sticklebacks Pungitius pungltius, yellow perch
Perca flavescens and mayfly subimagoes Ephemoptera sp. were the most important prey items in the lake. Long-term patterns of prey utilization by both predators showed considerable annual variation. Abundant white sucker and cyprinid species were not important in the diet of either walleye or northern pike, and may represent a net energy loss to the production of these two species.


title: Effect of rpoS inactivation on biofilm formation of a p-nitrophenol degrading Pseudomonas putida strain

subject:
Bioremediation

Biofilms

abstract:
With the widespread existence of environmental pollutants in the modern world,
effective, non-destructive means of remediation are becoming more and more desirable as an
alternative to the traditional excavation and incineration. Bioremediation, the use of pollutant degrading
biological processes to cleanse an area, is a highly viable and realistic option. In a
polluted area, organisms must be able to withstand a considerable amount of environmental
stresses. Both biofiims and the stationary-phase sigma factor, RpoS, have been shown to aid in
bacterial survival and thus their relationship to each other may provide clues to increasing the
survival of remediating organisms.
The effect of rpoS deletion on the biofilm forming ability of a p-nitrophenol degrading
Pseudomonas putida strain was examined. When examined in a simple Crystal Violet assay the
rpoA'-knockout mutant showed a greater amount of cells attached to the glass test tubes than did
the wild-type. This observation was mirrored by confocal microscopy images which showed a
greater amount of growth, quicker growth, and a greater degree of mature biofilm structure for
the knockout cultures versus the wild-type. Converted to quantitative results, all parameters of
biovolume, percent substrate coverage, thickness and roughness showed a significantly greater
difference between the knockout and the wild-type P. putida. There were no significant
differences in hydrophobicity values for the two cultures and it is unlikely that hydrophobicity
played a role in the observed biofilm differences. Taken together, these results indicate a close
relationship between RpoS and biofilm formation in P. putida, and are promising for future
bioremediation studies.


title: Examining adverse childhood experiences in a First Nations treatment-seeking population

subject: Childhood adversity (Indigenous populations in Canada)

subject: Mental health and wellness (First Nations)

subject: Adverse Childhood Experiences (ACEs)

abstract:
Experiencing adversity during childhood can disrupt typical developmental pathways and
consequently affect health outcomes throughout the lifespan (Norman et al., 2012), particularly
for Indigenous populations in Canada as they tend to experience greater health disparities when
compared to non-Indigenous populations (Statistics Canada, 2018a). To better understand these
relationships within Indigenous populations, the First Nations ACE study examined Adverse
Childhood Experiences (ACEs) in a First Nations population seeking substance use treatment,
including participant-reported ACEs and health outcomes of parents and grandparents using a
community-based participatory approach. Regression models assessed the relationship among
ACE scores and subsequent health outcomes reported by 141 individuals in an on-reserve
residential treatment program. Higher reported ACE scores were significantly associated with an
increased number of health concerns. Some study hypotheses were not supported despite being
supported with prior literature. Odds ratios of increased prevalence of specific diseases were not
significant, however trended in expected directions. Parent and grandparent ACEs and residential
school attendance were not significantly related to increased health concerns by participants,
although were associated with parenting difficulties. Future research with a larger sample size
may increase the power of analyses to detect clinically and statistically-relevant relationships
among these groups. When participant and staff experiences with First Nations ACE Study were
examined, participants generally reported positive experiences with the study, and staff members
reporting satisfaction with the CBPR practices embedded within the study.

abstract:
The present research was designed to investigate the
differences between Indian and white children on; (A) the
dimensions and attributes comprising self-concept; and (B)
the developmental changes in self-concept. in this study,
71 Indian and 149 white children between the ages of 8 and
13 years were tested on three measures of self-concept; (1)
the "Twenty Statements" Test (Kuhn & McPartland, 1954); (2)
Mohr's (1978) transformation tasks; and (3) a modified
version of the Piers-Harris Children's Self-Concept Scale
(Piers, 1969), In this investigation, a distinction was
made between two aspects of self-concept; (1) figurative -
which referred to the specific dimensions and attributes
that comprise self-concept; and (2) operative - which
referred to the underlying organization and structure of
the dimensions and attributes that are influenced by
development.
In the present investigation, a number of figurative
differences were found between the self-concept of Indian
and white children on the modified version of the
Piers-Harris, and on the "Twenty Statements" Test. ‘ The
self-descriptions of Indian children contained a greater
number of references made to; independence; family ties;
emotion; sharing; and respect for traditional customs and
beliefs, than white children. In addition, Indian children
were less positive in their attitude toward formal
education than white children. Furthermore, the self-description of Indian males contained fewer
references made to possessions, while the self-descriptions
of Indian females contained a greater number of references
made to their relationship with nature.
There were a number of changes with age in the
operative aspect of self-concept. First, self-concept was
found to become less externally orientated and more
internally orientated. This trend was shown for both
Indian and white children; however, based on the results
from the transformation tasks, the progression from
external orientation to internal orientation was
developmentally delayed in Indian children. Finally, there
was an increased emphasis on group membership for males
only.

Mythology

abstract:
Using arts-informed research and the intuitive artistic processes of drawing and painting
I searched for visual symbols and feelings in the myths of Artemis and Apollo. Visual
imagery, symbols and meaning provide a different understanding from standard
mythological texts. Artemis and Apollo represent the dualities of nature and the human
sphere. Artemis is a protector of young children and emerges as a role model for young
women today, while Apollo is associated strongly with the passing of time and
agriculture. Ways of understanding Artemis and Apollo that are relevant to youth and the
teaching of mythology can inform secondary level classrooms in Ontario. Artemis and
Apollo symbolize roles relating to sexuality and gender; lifecycles; and most importantly
the balance between wilderness and civilization as constructed by human.

abstract:
The analysis of influence in social network is drawing more and more attention. It can be applied in different areas such as political campaigns and marketing. In this work, the analysis of influence in Twitter, based on users‟ profile statistics in a real-time scale, was studied and discussed. Two methods of identifying influential users by given keyword in real-time are introduced.
To understand the relationship between users‟ influence features and social states in real life, two influence measures were presented: Local Influence which the user has on his/her immediate set of contacts and global Influence which the user has on the entire social network. This study describes in details these two metrics and shows their implementation for a real social network. Our case study, using Twitter, showed that the proposed model can create clusters of users in 2D space corresponding to their social standing, and can further be used to classify previously-unseen users into the correct classes with an f-measure of 0.82 which is significantly higher than benchmark algorithms. F-measure is often used for measuring the accuracy of the test for classification.
