Sports Expertise as a Predisposing Factor to Decisional Process Among Physical Education Teachers: A Case Study
No full textThis paper focuses on evaluating the impact of sports expertise as the embodied experience in a sports activity on the decisional process of an expert physical education teacher. Both qualitative and quantitative studies were applied within a mixed-approach using a single case study. A clinical didactics methodology was employed with three important tenses of the teaching practice (already-there, test, after-work). To understand the internal determinants that monitor the teaching practice of our participant, semistructured interview was used, in situ filmed observation and content analysis.
Results indicate that personal determinants, the experiential and embodied “already-there” related to sports expertise, have a significant impact on the “personal” relationship to knowledge and the bodily awareness. This can be noticed by the way knowledge is delivered through a high recurrence to direct
physical ostension demonstration by the teacher’s body. Sport expertise is a major determinant of teacher’s pedagogical and didactical conducts resulting from a subjective decisional process
Lutte contre l’insécurité alimentaire et la malnutrition dans les pays sahéliens :l’aquaponie comme alternative : le cas du Burkina-Faso
Get PDFLe présent mémoire de fin de cycle d’études a pour but dans un premier temps d’analyser les causes et les conséquences de la situation de l’insécurité alimentaire et la malnutrition dans les pays sahéliens en Afrique et particulièrement au Burkina-Faso. Ensuite, il propose le Système Aquaponique, une nouvelle technique culturale innovante comme une autre alternative de lutte contre l’insécurité alimentaire et la malnutrition au Burkina-Faso.
La méthodologie utilisée se base sur les revues littéraires scientifiques et les différentes approches explicatives de l’insécurité alimentaire et la malnutrition afin d’analyser ses causes et ses conséquences sur les populations du sahel et au Burkina Faso. Il examine les initiatives et les solutions déjà développées telles que la culture de contre saison, les techniques culturales telles que le Zaï (une technique culturale traditionnelle pratiquée par les populations du Nord du Burkina Faso), les cordons pierreux et enherbés, les diguettes pour atteindre l’autosuffisance alimentaire ainsi que leurs limites.
Il ressort que le système agricole aquaponique, une technique innovante combinant l’élevage de poissons et la culture des végétaux dans un dispositif de circuit fermé présentent des avantages permettant d’atteindre l’autosuffisance alimentaire au Burkina Faso. Ce système agro écologique innovant utilise 5 à 10% d’eau comparée à une agriculture conventionnelle. Il offre de meilleurs rendements tout en maximisant les espaces exploitables

and Community Services. Nogdawindamin Family and Community Services is a child welfare
agency that was created and is governed by the seven First Nations along the North Shore in
Ontario, Canada. Nogdawindamin Family and Community Services is a multi-service agency
that provides child welfare service among many other programs including Child Mental Health,
Adult Mental Health, Youth in Transition, and many others that are aimed at addressing the
challenges that their communities face. Further, the focus of my advanced practicum was to
develop a better understanding of how I, as a non-Indigenous person, could work with
Indigenous people in the context of child welfare in a good way. This report discusses what I
learned from the literature and from my practicum experience with the InvestigationMaster of Social Work Progra
Data balancing for credit card fraud detection using complementary neural networks and SMOTE algorithm
No full textThis Research presents an innovative approach towards detecting fraudulent credit card
transactions. A commonly prevailing yet dominant problem faced in detection of fraudulent
credit card transactions is the scarce occurrence of such fraudulent transactions with respect to
legitimate (authorized) transactions. Therefore, any data that is recorded will always have a stark
imbalance in the number of minority (fraudulent) and majority (legitimate) class samples. This
imbalanced distribution of the training data among classes makes it hard for any learning
algorithm to learn the features of the minority class. In this thesis work, we analyze the impact of
applying class-balancing techniques on the training data namely oversampling (using SMOTE
algorithm) for minority class and under sampling (using CMTNN) for majority class. The usage
of most popular classification algorithms such as Artificial Neural Network (ANN), Support
Vector Machine (SVM), Extreme Gradient Boosting (XGB), Logistic Regression (LR), Random
Forest (RF) are processed on balanced data and which results to quantify the performance
improvement provided by our approach. The experiments show that the hybrid approach which
integrates Complementary Neural Network and Synthetic Minority Oversampling Technique
gives a Quantitative performance in terms of Accuracy of 99% and 99.7% of AUC with Random
Forest Classification Algorithm compared to simple undersampling and oversampling
Laurentian University Truth and Reconciliation Taskforce: Final Report
No full textIn 2015, the Truth and Reconciliation Commission of Canada (TRC) released 92 Calls to Action (4) aimed at government, public institutions and private industry. These Calls to Action seek to address the legacy of harm inflicted on the Indigenous population through the system of Indian Residential Schools. These recommendations seek to advance expressions of reconciliation, and promote social justice and equity for Indigenous peoples in all spheres.
According to the TRC, universities and colleges as key educational institutions have a pivotal role in championing reconciliation in society. Laurentian University for its part, has expressed its commitment to "support Truth and Reconciliation Commission Calls to Action and will respond by creating a task force to identify priority actions, beginning by offering cultural safety training and opportunities to learn the Anishnaabemowin language to faculty, staff and students".
In this report, a number of measures have been identified by the Laurentian University Truth and Reconciliation Taskforce. Laurentian University and the federated universities, its affiliated partners, are strongly encouraged to consider implementing these recommendations
Analyse de pratique en approche familiale auprès d'enfants et d'adolescents hospitalisés dans un contexte de crise psychiatrique
No full textLes problèmes de santé mentale atteignent les personnes de tout âge, incluant les enfants et les adolescents. Dans cet essai, je m’intéresse à mieux comprendre les bienfaits de la thérapie familiale chez les jeunes dans un contexte de crise psychiatrique par l’analyse de mon stage spécialisé à la maîtrise en service social, avec le Programme de santé mentale pour enfants et adolescents (PSMEA). Ce programme est une unité hospitalière
de courte durée qui offre des services intensifs aux enfants et adolescents âgés de moins de 18 ans qui ont des problèmes de santé mentale sévères.Dans cet essai, j’expose les deux théories qui m’ont aidée à comprendre mon lieu de stage spécialisé (l’intervention de crise et la thérapie familiale), ainsi que le modèle
d’intervention systémique d’Amiguet et Julier (1996) que j’ai choisi pour faire l’analyse de mon stage. Par la suite, je présente une étude de cas en utilisant ce même modèle d’analyse afin de mieux comprendre l’interdépendance entre le système-client et le système-intervenant où chacun des huit repères a un effet sur l’autre. Lors des rencontres et suite à mon analyse, j’ai remarqué l’importance de l’implication de la famille dans la vie de leur enfant durant ces périodes de crise psychiatrique. De plus, j’ai réalisé l’importance fondamentale de la relation thérapeutique puisque c’est à travers cette relation que la famille se sent entendue, validée et encouragée. Cette validation renforce les capacités parentales et leur désir de s’investir dans la famille malgré les défis, puisque chacun a un rôle à jouer au maintien du problème et sa résolution.Maîtrise en service social
Morphometric changes with age in human trabecular bone structural units (BSU) of the lumbar spine
No full textAge-related fractures are common at skeletal sites with high proportions of cancellous bone such
as the hip and spine. Research has shown that measures of bone quantity alone are imperfect
predictors of fracture risk, so recent efforts have focused on combining them with measures of
bone quality. One aspect of quality that has received little attention is the microstructure of the
trabeculae themselves, which are composed of a patchwork of bone structural units (BSU), also
known as hemiosteons or trabecular packets, bonded together by cement lines. Any changes in
the size of the BSU can be expected to affect the mechanical and failure behavior of cancellous
bone. The present work quantified morphometric changes in BSU from the vertebra of 8 young
and 8 old individuals as a function of age and 3-D architectural parameters. Reductions in the
size of BSU and increases in the proportion of cement line were found to occur with ageing, but
these changes were more highly correlated to deteriorating cancellous architecture. These
relationships, and the mechanical implications of smaller BSU and increased amounts of brittle
cement line, require further investigation
Applicability of remote sensing technologies for use in Ontario forest fire management protocols
No full textThe use of remote sensing in forest fire detection could allow earlier mitigation of active fires resulting in a significant decrease in fire related health effects. Infrared detection can provide more detailed and accurate information on fire size, spatial accuracy and temperature. Hyperspectral sensors can allow the detection and earlier mitigation of high risk areas. Few studies have concentrated on the efficiency of multiple types of sensors surch as infrared, hyperspectral and multispectral being used in combination. A literature review was done to highlight health effects on humans and the environment in order to determine the need for changes in current forest fire detection practices. The infrared portion of this research focused on sensors abilities to detect heat signatures and compared the specifications of each sensor with the others to ensure a cost-effective solution to current practices using off-the-shelf technologies. The hyperspectral portion of this research focused on using vegetation indices to examine potential use of such sensors in the detection of high risk areas
Uncertainty-based mine planning framework for oil sands production scheduling and waste management
No full textIn open pit mining, the most significant challenge is determining the optimum long-term
production schedules that maximize the project value by providing ore to the processing
plant at full capacity while satisfying all required constraints. For oil sands strategic mine
planning and waste management, as mining advances in a specified direction, in-pit tailingscells’ dyke footprints are released for dyke construction. The dykes are constructed from
overburden, interburden and tailings coarse sands dyke materials which come from the
mining operation. The construction of in-pit (and ex-pit) tailings impoundment dykes
therefore needs to be well integrated with the waste management strategy to ensure
regulatory compliance and sustainable mining.
In this research, an uncertainty-based mathematical programming framework is developed
based on mixed integer linear goal programming (MILGP) model for oil sands production
scheduling and waste management. The effect of grade uncertainty on production schedules
is investigated. The grade uncertainty financial risk associated with a production schedule is
minimized using kriged estimates with a variance penalty scheme. This investigation is
based on the concept of mean-variance analysis, which is the process of weighing variance
(risk) against the expected net present value (NPV). Subsequently, the impact of organic rich
solids (ORS) content on bitumen recovery during processing is also studied. ORS content is
used to predict ore processability in addition to the traditional use of bitumen and fines
contents, and its impact on NPV quantified. The developed MILGP model is implemented
using new robust automated production targeting (APT) constraints that optimize the annual
capacities for material mined and processed over the mine life. In addition, mining-cells are
deployed for the generation of in-pit tailings-cells designs used as dedicated disposal areas
for backfilling.
Two main waste management approaches are used to implement the developed model.
Implementation A; where the ultimate pit is divided into predetermined pushbacks as
tailings-cells within the ultimate pit limit (UPL), and Implementation B; where the ultimate
pit is divided into mining-cells that are used to generate in-pit tailings-cells designs. To
verify the research models, three oil sands case studies were carried out. The first case study investigates the effect of grade uncertainty on production schedules. The
technique applied is based on the concept of mean-variance analysis, which is the process of
weighing risk (variance) against expected NPV. The model generates a range of NPV which
represents the mining investment risk profile associated with grade uncertainty. The second
case study explores the impact of ORS content on oil sands ore processability. The results
showed a 3.46% overestimation of NPV arising from not taking into account the effect of
ORS content on bitumen recovery during mine planning. The final case study examines the
implementation of waste management strategies based on different size and number of unit
mining-cells used in creating tailings-cells for backfilling. The results showed that,
decreasing the volume of unit mining-cells used in creating the in-pit tailings-cells increases
the NPV of the operation due to increased operational flexibility. Additionally, as the
percentage of in-pit volume to be backfilled increases, more savings is generated from not
sending tailings to external facilities at a higher cost. These results proved that the
uncertainty-based MILGP model is a robust tool for optimizing oil sands long-term
production schedules whilst taking into account grade uncertainty, ore processability and
tailings-cells designs.Doctor of Philosophy (Ph.D.) in Natural Resource Engineerin
