L'ascolto della regressione nel processo analitico
Authors: Gabriel Sapisochin
Published: June 2021

Partendo dalla supposizione secondo la quale la nozione di regressione libidica appartiene a un modello di psichismo statico, chiuso al legame con l'altro e organizzato in maniera invariante, l'Autore considera che la comparsa dell'arcaico nella seduta psicoanalitica implichi un modello di psichismo inteso come un'Organizzazione Funzionale con differenti livelli di funzionamento e di rappresentazione simbolica. Propone l'idea di uno psichismo arcaico, concepito come inconscio non rimosso, risultato delle attribuzioni proiettive trau- matiche dell'inconscio genitoriale, che cerca espressione e rappresentazione attraverso l'agire nei diversi contesti nei quali si elabora la realtŕ psichica. L'Autore ritiene che l'idea di uno psichismo che si esprime e rappresenta attraverso la ripetizione messa in atto č la conseguenza logica di un modello di soggetto psichico aperto alla generazione di senso nel rapporto con l'altro dello spazio intersoggettivo, che ha cessato di essere un oggetto contingente. Pensa che la nozione freudiana di agieren implichi un cambiamento nella teoria dell'ascolto psicoanalitico, dato che il transfert cessa di essere soltanto lo spostamento delle rappresentazioni intrapsichiche per costituirsi come un fenomeno inter-soggettivo indissolubilmente legato al controtransfert. Č per questo che egli ritiene che il transfert, ormai legato alla posizione controtransferale inconscia, superi il modello della prima teoria delle pulsioni e della prima topica freudiana. Riflette sull'uso strumentale della regressione nel processo analitico, sostenendo che essa, accogliendo la rappresentazione scenica di una particolare configurazione arcaica intrasoggettiva dell'analizzando, iscrittasi come gesto psichico non pensato verbalmente, crei le condizioni per una nuova forma di rappresentazione, conciliabile con il pensiero verbale dell'Io, distante dalla ripetizione messa in atto e suscettibile di risignificazione infinita.
Il contributo della pulsione di morte alla trasmissione transgenerazionale della vita psichica inconscia
Authors: Stella Amedeo
Published: June 2021

Il presente lavoro propone un percorso di rivisitazione della nozione clinica di pulsione di morte, all'interno di una cornice costituita dalla teoria di Balint sul "difetto fondamentale", gli ultimi studi di Ferenczi sui contesti relazionali dei processi d'identificazione in rapporto al trauma, le riflessioni di Green sul "lavoro del negativo". Osservando il modo in cui queste tre prospettive s'incontrano nell'osservazione clinica, č possibile affermare che il vettore inconscio della trasmissione transgenerazionale del trauma č rappresentato dalla situazione in cui l'area del difetto fondamentale costituisce un elemento fondamentale del campo intersoggettivo inconscio. Il lavoro collusivo inconscio compiuto dall'area del difetto fondamentale e dalle identificazioni negative genera processi di defusione pulsionale, di scissione e d'idealizzazione che finiscono per liberare, anche a dispetto delle intenzioni coscienti, quote significative di pulsione di morte, odio e invidia, che costituiscono nuclei insidiosi di distruttivitŕ. L'efficacia di queste ipotesi č supportata attraverso l'esame di due casi clinici.
Race, Space and Place: Exploring Toronto’s Regent Park from a Marxist Perspective
Authors: Sahak Jaihun
Published: June 2021

Regent Park, a multi ethnic immigrant community situated in the centre of downtown Toronto, is the poorest neighbourhood in Canada. Using the spatial triadic theory of French Marxist Henri Lefebvre, Vanessa Rosa’s reformulation of his theory and Sherene Razack’s concept of “Place becomes Race”, the aim of this paper is to demonstrate that Regent Park has become a racially produced space through spatial practice, representations of space and representational spaces. In addition to Lefebvre, the writings of Frederick Engels, Louis Althusser, Antonio Gramsci and David Harvey will also be examined to put into context the historical significance of the existence of Regent Park in a capitalist society. This paper will analyze why Regent Park was built, who developed it, and who were the original residents. And the conclusion, that Regent Park was produced as a marginalized and racialized space within the periphery of the center, will be discussed.
Design and Application of Signal Modeling, Segmentation and Classification Methods for High-Frequency Ultrasound Backscatter Signals
Authors: Farnoud Noushin R.
Published: June 2021

In this study, we explore the possibility of monitoring program cell death (apoptosis) and classifying clusters of apoptotic cells based on the changes in high frequency ultrasound backscatter signals from these cells. One of the hallmarks of cancer is that the fail [sic] in the apoptosis mechanism in cells. Therefore this research carries the promise of designing more refined and more effective cancer therapies. The ultrasound signals are modeled through the Autoregressive (AR) modeling technique. The proper model order is calculated by tracking the error criteria derived from statistical properties of the original and modeled signal. In the next stage, five machine learning classifiers are developed to classify backscatter signals based on their AR coefficients. In clinical applications ultrasound backscatter signals from tissues and tumors are most likely to be non-stationary. Therefore analyzing such signals requires signal segmentation techniques. We developed recursive least square lattice filter for adaptive segmentation of ultrasound backscatter signals from multiple cell types into blocks of stationary segments, and model and classify the segments individually. In this thesis we demonstrate the accuracy of modeling, segmentation and classification techniques to detect signals from different cell pellets based on the signal processing and machine learning techniques.
John Beasly Greene
Authors: Topham Rachel
Published: June 2021

This thesis focuses on the life and work of John Beasly Greene, photographer, archaeologist and Egyptologist. I describe Greene's early life, his training in photography with Gustave Le Gray in 1852, his two trips to Egypt in 1853 - 1854 and 1855, his trip to Algeria in 1855 - 1856 and his death in November 1856. I also consider the process and printing of his Egyptian negatives, their number and current location, and whether his book "Le Nil. Monuments - Paysages, Explorations Photographiques Par J.B. Green" (sic) was ever published. In my research I discovered that four separate images of Algeria in the collection of the Museum of Modern Art, New York constitute two panoramas.
Why are the Lights so Dim? Institutions Educating the Public on Photographic Preservation
Authors: Guram Suman  K.
Published: June 2021

With the emergence and expansion of the field of Photographic Preservation, it is important and beneficial to explain preservation initiatives on display to the audiences that we are engaging and preserving for. This assists in facilitating a public understanding of photographic preservation, as well as building relevance to the institution’s collections and mission. This project is concerned with the role interpretation plays in the visitor’s experience, specifically through text labels and seeks to gain insight into the ways museums educate their audiences about the special care required to exhibit photography. This data was collected by conducting a series of interviews with various institutions, as well as conversations with professionals in the field. Using these findings and appropriate research, four piece labels were created that would accompany and explain four differing preservation strategies in exhibitions: facsimile prints, timed light boxes, the use of drapery and low light levels.
A mobile mapping system utilizing a spherical camera
Authors: Alleva Craig
Published: June 2021

The transportation departments belonging to respective provinces currently collect highway management data with the use of several methods and systems which include visual field inspections, survey methods, aerial photogrammetry, as well as mobile data acquisition systems. Spherical cameras offer an attractive alternative to standard mobile data acquisition devices for highway management systems as they provide full coverage with a single camera. Inclusion of such a camera requires methods of determining relative, interior and exterior orientation information, as well as bore-sight and lever arm determination. Specialized methods of mosaicking[sic] the imagery are also required.

This paper focuses on exploring these methods for spherical cameras. Several computer programs were developed to solve for relative, interior, and exterior orientation parameters. It was concluded that a spherical camera can be efficiently utilized for highway data collection and provides full data coverage with a single camera system.
In defense of traditional knowledge: the case of Bt brinjal and challenges to the international intellectual property agenda
Authors: Millar Edward Evan
Published: June 2021

Theories on the globalization and harmonization of intellectual property law tend to take a state-level approach when discussing the impacts of large-scale harmonization of patent laws on developing countries. This paper uses a case study of the Indian experience of adapting to international treaty mandated changes to domestic patent law and the 2011 announcement of an IP lawsuit over the alleged biopiracy of genetic material from a traditional Indian plant variety, and connects the experience of an individual country to the wider body of research and theory that exists on the relationship between IP and development for non-Western countries. The paper also provides a discourse analysis of the public reaction, as covered by English-language Indian newspapers, to the lawsuit launched against Monsanto, the Maharashtra Hybrid Seed Company, the University of Agricultural Sciences, Dharward, and the Tamil Nadu Agricultural University by the governmental organization the National Biodiversity Authority over the development of the transgenic Bt brinjal crop.
HOV access location analysis at Erin Mills Parkway and Highway 403
Authors: Kakakhel Makael
Published: June 2021

High Occupancy Vehicle (HOV) lanes are one [of] the most commonly used methods to reduce the number of vehicles on the road network. HOV provides a faster and reliable option to single occupancy vehicles, thus inducing more people to car pool. The success of HOV lanes depends on the reduction of travel time and increased trip reliability. Therefore, in order to reduce travel time and improve trip reliability this study emphasizes on the HOV access location relative to an access ramp. In this case we have chosen the interchange at Erin Mills Parkway and Highway 403 as a subject of our study. The study was divided into 2 parts, namely the field review and simulation of different options in order to optimize the HOV access location. During the field review it was found that 75% of the vehicles are in a position to enter the HOV lane 200m upstream of the exiting access location. Also, approximately 35% of vehicles were jumping the buffer before the start of the access location. In the second part of the study a total of 6 options were explored using VISSIM micro simulation software. The results of the simulation showed that the access location 200m downstream of the Speed Change Lane with a total access length of 600m is the best option. In addition, it was found that buffer separated HOV lane operate better then HOV lane without a buffer zone. This can be attributed to the increase of HOV lane for short trips, which increases the traffic volume on the HOV lane.

Authors: Givogue Jennifer
Published: June 2021

This thesis is an applied project in which a finding aid was created for the set of George Streynsham Master's albums held in the Richard and Ronay Menschel Library at George Eastman House International Museum of Photography and Film. The collection consists of twenty-one travel and autobiographic albums compiled by the English clergyman George Streynsham Master (1823-1900). The albums range in date from the 1850s through the 1890s, and include tipped-in albumen prints, lithographs, paintings, drawings, newspaper clippings, correspondence and hotel receipts. The museum acquired the albums in 1953 as part of the Alden Scott Boyer (1887-1953) collection. My thesis is divided into two parts, the first part describing the process and development of the finding aid, and the second comprising the finding aid itself, which is divided into ten sections: 1) The Creation of the Albums, 2) Provenance of the Collection, 3) Chronology, 4) Scope and Content of the Collection, 5) Album Inventory of Autobiographic Albums, 6) Album Inventory of Travel Albums, 7) List of Photographers and their Biographies, 8) Master's Use of Nineteenth-Century Guidebooks, 9) Bibliography of George Streynsham Master's Publishing Writings, and 10) References. The finding aid is accessible to researchers in the Menschel Library at George Eastman House.
Fuzzy Similarity Measure and its Application to High Resolution Colour Remote Sensing Image Processing
Authors: Li Yu
Published: June 2021

The focus for the study in this thesis is placed on developing basic algorithms and tools for high-resolution colour remote sensing image processing tasks such as colour morphology, multivariate clustering, and multivariate filtering. First, the fuzzy similarity measure (FSM) among vectors in a vector space is introduced. This measure is based on two assumptions for the relationship among vectors: short-range ordering and fuzzification. Second, based on the FSM, the colour morphology, multivariate fuzzy clustering, and multivariate filtering are defined. The performances of all proposed methods will be evaluated numerically and subjectively. Third, this study also places more emphases on solving some applied problems related to recognizing colour edges, detecting and extracting complex road network and building rooftops, and reducing noise in high-resolution remote sensing images such as QuickBird, Ikonos, and aerial images. The results obtained in the study demonstrate the effectiveness and efficacy of the FMS and the proposed methods.
Temperature and shrinkage cracking in reinforced concrete walls
Authors: Matin Dylan James
Published: June 2021

Concrete cracking due to restrained thermal and shrinkage strain is a widespread problem that could happen to any structural element including base restrained walls. This type of crack usually occurs in structures with rigidly interconnected parts cast after their adjacent parts are hardened. As concrete undergoes volumetric deformations right after casting, the developing strains due to temperature drop and moisture loss get restrained by neighboring parts which causes stress development and could lead to formation of cracks. Cracking could reduce the structure’s integrity and serviceability, cause deterioration which could also lead to esthetical concerns. Therefore, structures should be designed to limit cracks to an acceptable level depending on the functionality requirements of the structure and its exposure conditions. Although it has been proven that it is almost impossible to completely eliminate cracking, providing an adequate amount of appropriately positioned reinforcement can reduce the width of cracks significantly. This study aims to investigate the behavior of base restrained reinforced concrete (RC) walls under volumetric changes due to thermal and shrinkage strains and providing a procedure to determine the amount of reinforcement needed to control the width of cracks. The ABAQUS finite element (FE) program is used to simulate the structures used in this study. The models are verified by comparing the results with previous experimental studies. Based on the performed parametric study, a procedure is suggested to determine the amount of steel reinforcement required to satisfy the cracking limitations based on major parameters that affect the crack width.

Authors: Ming Jinjie
Published: June 2021

This project describes the development of an automatic segmentation method and a novel navigation system that detect polyps using advanced image processing and computer graphics tecniques. The colon wall segmentation method from the CT data set of abdomen is achieved by combining the contouring model - level set method and the minima detection using mathematical morphology theory. Polyp detection is attained by analyzing surface curvature and texture information along on the colon wall. Adding texture analysis provides a new feature for improving currently existing methods. As such, polyp candidates are examined not only by their shape and size but also by their texture appearance.
Negotiating success or settling for less? : deconstructing the underachievement of Afro-Caribbean youth in Toronto high schools
Authors: Stennett Pasha
Published: June 2021

The academic underachievement of students from the African Diaspora in Canadian schools is not a recent phenomenon. Afro-Caribbean students are reported to drop out of high schools in Toronto at disproportionate rates. To uncover the social forces that contribute to these problems this paper will examine Afro-Caribbean patterns of community formation and the issue of systemic racism in Canadian society operating as a barrier to academic success.

At an even greater rate Portuguese youth are leaving school prematurely. But unlike with Afro-Caribbean students racism is not an issue. Rather for the majority of Portuguese students in Canada the reasons behind chronic underachievement are rooted in the current education system, which views immigrants as different and the source of their own failure. This paper uncovers the subtle forms of racism that many underestimate and the huge role it plays in dictating the lives of many youth from the Black community.
Comparing the Environmental Impacts of Diesel Generated Electricity with Hybrid Diesel-Wind Electricity for off grid First Nation Communities in Ontario : Incorporating a Life Cycle Approach
Authors: Schofield Jade
Published: June 2021

The cost of diesel is rapidly increasing and the environmental impacts associated with diesel fuel combustion are substantial. Hybrid diesel-wind energy was found to be a feasible energy alternative for off-grid electricity production in seven First Nation communities of Ontario. Based on calculating the wind energy potential for a proposed 250 KW wind turbine and determining the amount of diesel that the wind turbine could replace hybrid diesel-wind has the potential to reduce diesel consumption and environmental impacts associated with the current diesel energy systems by 12-46% depending on the wind energy potential. Results of a life cycle analysis comparing the environmental impacts of the proposed hybrid diesel-wind system to the diesel system through the use of GaBi software show that global warming potential is the largest impact for both energy systems, but hybrid diesel-wind can significantly reduce the overall environmental impact caused by off grid diesel electricity generation.
John R. Connon of Elora, Ontario and his 360-degree panoramic camera
Authors: Rowbotham Cassandra
Published: June 2021

John R. Connon (1862-1931) was a photographer and inventor who lived in Elora, Ontario, Canada during a time of remarkable innovations in the medium of photography. In 1886, Connon began to develop one of the earliest cameras to be capable of a full 360-degree photographic panorama using a single exposure. His early dedication to the use of flexible roll film, introduced by the Eastman Dry Plate and Film Company in 1885, allowed Connon to invent a camera that was ahead of its time. Through an agreement with C. P. Stirn, of C. P. Stirn's Patent Photographic Concealed Vest Cameras, Connon's design was transformed into the Wonder panoramic camera, further inspiring a succession of full-circle panoramic cameras including the Kodak Cirkut cameras. This thesis explores the history of Connon and his invention while acknowledging the history of this little-known Canadian inventor’s important contribution to the history of photographic technology.
Seismic Response of Ground-Supported Circular Concrete Tanks
Authors: Hafez Ahmed
Published: June 2021

This study is focused on the nonlinear behavior of ground-supported open top circular concrete tanks under the effect of seismic loads. The tank support conditions are considered in this study where both flexible and nonflexible supports are investigated. A comparison between the behavior of reinforced concrete (RC) and prestressed concrete (PC) tanks is undertaken for flexible base condition. The finite element (FE) method is used to study the nonlinear response of circular tanks under dynamic time-history and push-over analysis. Furthermore, the response modification factors (R) included in current practice are evaluated based on the results of nonlinear dynamic and push-over analysis. Several tank configurations with different aspect ratios, construction method, and base conditions are used in this study to attain reliable results and to validate the Rvalues. The behavior of circular RC tanks under shrinkage effect is also investigated. Moreover, an innovative approach is presented in this study for flexile base tanks in order to further reduce the seismic response of these structures by using passive energy dissipation systems such as fluid viscose dampers (FVD). The results of this study show that higher R-values could be applied to fixed base tanks as compared to hinged base tanks. Also, shallower concrete tanks can be assigned higher R-values as compared to tall tanks. The results of this study show that the type of construction affects the tanks ductility. PC tanks show lower ductility as compared to RC tanks. Furthermore, this study shows that the flexible base tanks with seismic cables do not dissipate the seismic forces, as expected, due to the elastic behavior of the seismic cables. Based on the results of the FE analysis, it is shown that, using FVD reduces the tank response under seismic loads. The use of FVD improves the tank serviceability by reducing the concrete cracking. It is concluded that flexible based tanks equipped with FVD can be used as an economically feasible system in high seismic zones.
Using multiple linear regression to disaggregate electricity consumption for cluster-metered academic buildings
Authors: So Nicholas
Published: June 2021

Ryerson University does not have a means to gauge electricity consumption for half of their campus buildings. The installation of utility meters is outside of the University’s budget, a situation that may be similar across other academic institutions. A multiple linear regression approach to estimating consumption for academic buildings is an ideal tool that balances performance and utility. Using 80 buildings from Ryerson University and the University of Toronto, significant building characteristics were identified (from a selection of 18 variables) that show a strong linear relationship with electricity consumption. Four equations were created to represent the diversity in size of academic buildings. Tested using cross-validation, the coefficient of variation of the RMSE for all models was 33%, with a range of error between
20% and 43%. The models were highly successful at modeling electricity consumption at Ryerson University with an average error of 14.8% for five building clusters. Using metered data from each cluster, raw estimates for individual buildings were adjusted to improve accuracy.
Authority in Canadian news : an examinatin of the voices, perspectives and interests favoured by Canadian broadcasters
Authors: Godo Elizabeth
Published: June 2021

While the mainstream new media can be said to play a variety of roles, what is certain is its potential to inform public opinion and our understanding of the world we live in, both on a national and global scale. One of the ways this is accomplished is through the use of authority; the active decision by media outlets to invoke the trust we have in certain voices while reflecting and shaping our notions of the roles of others. When given the choice between experts, political leaders, victims, etc., all genders and cultural backgrounds, whose voices are heard in mainstream media, and as a result, whose influence is reflected in the public's understanding of the world; an understanding so crucial to a functioning democracy? Filing in the gaps in this under researched area, this thesis explores the issue of how authority plays out in the Canadian national context.
Revisiting The 1910 International Exhibition Of Pictorial Photography
Authors: Youngman Andrew T.
Published: June 2021

This thesis constructs a history surrounding the organization and hanging of the 1910 International Exhibition of Pictorial Photography, which was arranged by Alfred Stieglitz and the Photo-Secession for the Buffalo Fine Arts Academy at the Albright-Knox Art Gallery (then the Albright Art Gallery). This history identifies those involved in the planning and execution of the exhibition and is presented as a timeline of events revealed largely through correspondence between Stieglitz and Cornelia Sage, Director of the Albright Art Gallery. This thesis also examines in detail the installation of the 594 selected works exhibited at the Buffalo institution. In addition, this thesis project outlines the procedure of developing a small exhibition to honor the centennial anniversary of the International Exhibition of Pictorial Photography. Presented to the curatorial staff at George Eastman House International Museum of Photography and Film in Rochester, New York, the proposed exhibition is intended to hang during the 2010 calendar year.
Privacy in mobile learning applications: user privacy concerns and implications of applying privacy by design approach
Authors: Ilkina Daria
Published: June 2021

This thesis investigates the privacy risks that m-learning app users face by identifying the personal information that m-learning apps collect from their users, and the privacy policies of these apps. It reveals that most of the m-learning applications have similar privacy policies, which seem to protect the interest of the providers rather than the users. The Privacy by Design framework is reviewed to determine whether it can help the developers address user privacy practices. The results from the sample of 260 participants suggest that users are less concerned with the collection of personal information that is non-identifiable. The survey also revealed that the users are more concerned when an app shares their personal information with third parties for commercial purposes than when it is shared with the government.
Providing Enhanced Digital Access to a Collection of Material Photographs: a Considered Approach
Authors: Buckley Ryan
Published: June 2021

The material-turn in photographic studies reveals that photographs cannot be correctly understood without direct interpretation of their physicality; however, institutions with photograph collections are increasingly offering digital access to these physical objects. With the benefits of digital access being too great to ignore, this research determines how a public institution can best enhance access to a collection of material photographs through digital media, while maintaining the core needs of the institution, its users, and the meaning of the photographs themselves. Using the Charles Chusseau-Flaviens collection at George Eastman House as an example, this research reveals practical benefits of combining Web 2.0 technologies such as Flickr with Encoded Archival Description (EAD) into an effective and efficient collection-level finding aid. This thesis presents an approach to providing enhanced digital access to a large collection of photographs while considering their materiality. The resulting finding aid can be found at: http://www.ryanbuckley.ca/findingaid/chusseau-flaviens.xml.
Taking the reins: a proposal for managing the previously unmanaged Royal Agricultural Winter Fair Archive
Authors: Masters Victoria
Published: June 2021

The Royal Agricultural Winter Fair (The Royal) has been a renowned national event in Toronto’s history since its debut in 1922. The annual fair is held for 10 days each November, and is the largest combined indoor horse show and agricultural fair in the world. As The Royal approaches its centenary year, the timing was perfect to deeply examine the previously-unmanaged collection of over 180,000 photographic objects and ephemera, and nearly seven metres of textual material, that has accumulated over the span of its rich history. Through a thorough review of the collections content and advice for both physical storage of the collection and collections management software options including digital storage, this thesis presents a list of recommendations for creating an accessible archive of this material, a resource that will enable this wonderful collection of important local, provincial, and national history to be preserved and made available to the public.
Gender and consumerism in Nickolas Muray's photography for McCall's magazine, 1933-1945
Authors: Roze Katherine
Published: June 2021

This thesis examines aspects of gender and consumer culture in Nickolas Muray's photographs for McCall's magazine from 1933 to 1945. It emphasizes the fluidity of meaning from image content to magazine context and includes two image indexes of Muray's images for McCall's from 1933 to 1945. One features original photographs and the other, published images. McCall's was a mass circulating women's magazine designed for the middle class homemaker. Muray's photographs for McCall's had the dual responsibility of representing the magazine's identity and the reader's idealizations. His images reflected expectations and perpetuated stereotypes of the American woman. At times, her role embodied traditional female values and at other times, it embraced modem womanhood and consumer culture. The latter was continuously amplified by the context of the magazine. These aspects of her role did not conflict. Rather, they complemented one another and characterized the diversity and limitations of her identity.
Plus ça Change? – A Comparative Analysis of the Seasonal Agricultural Workers Program and the Pilot Foreign Worker Program for Farm Workers in Quebec
Authors: Lowe Sophia J
Published: June 2021

For the last 40 years, migrant farm workers from the Caribbean and Mexico have been recruited to work temporarily on Canadian farms under the Seasonal Agricultural Workers Program (SAWP). In 2002, the pilot Foreign Worker Program (FWP) for low skilled migrant workers was initiated in the province of Quebec and under this program began the recruitment of Guatemalan migrant farm workers. Since the program's start, the number of Guatemalan migrants has nearly tripled and there seems to be a decline in the number of workers hired under the SAWP in Quebec. This paper examines the FWP's development, set-up, consequences and operation alongside the SAWP and shows how the Canadian state is expanding the number of flexibility and temporary worker programs. This paper draws attention to the neo-liberal context of migrant farm labour in Canada, pointing to the ways in which Canada's federal policies governing seasonal agricultural migrants and athe agricultural labour market are exploitative and racist.
Are the Effects of Poverty and Victimization on Criminal Recidivism Mediated by Depression as Predicted by General Strain Theory? A Longitudinal Study of Provincially Sentenced Women
Authors: Newman Jennifer E.
Published: June 2021

The current study is a longitudinal analysis of psychosocial factors contributing to re-offending among 125 adult female offenders. Drawing on General Strain Theory (GST), the study examined the role of victimization and poverty on criminal recidivism and investigated whether this relationship was mediated by depression. Regression, survival, and mediational analyses were employed to examine the impact of these variables on criminal recidivism. Findings revealed that using illegal means to make ends meet, and having survived childhood sexual abuse, were particularly important predictors of recidivism for women in the study sample, although depression was not found to significantly mediate the relationship between strain and recidivism. Implications for future research on female recidivism and helping women to stay crime-free are discussed.
Obstacle detection using Microsoft Kinect
Authors: Zeller Niclas
Published: June 2021

This thesis presents the development of image processing algorithms based on a Microsoft Kinect camera system. The algorithms developed during this thesis are applied on the depth image received from Kinect and are supposed to model a three dimensional object based representation of the recorded scene. The motivation behind this thesis is to develop a system which assists visually impaired people by navigating through unknown environments. The developed system is able to detect obstacles in the recorded scene and to warn about these obstacles. Since the goal of this thesis was not to develop a complete real time system but to invent reliable algorithms solving this task, the algorithms were developed in MATLAB. Additionally a control software was developed by which depth as well as color images can be received from Kinect.
The developed algorithms are a combination of already known plane fitting algorithms and novel approaches. The algorithms perform a plane segmentation of the 3D point cloud and model objects out of the received segments. Each obstacle is defined by a cuboid box and thus can be illustrated easily to the blind person. For plane segmentation different approaches were compared to each other to find the most suitable approach. The first algorithm analyzed in this thesis is a normal vector based plane fitting algorithm. This algorithm supplies very accurate results but also has a high computation effort. The second approach, which was finally implemented, is a gradient based 2D image segmentation combined with a RANSAC plane segmentation (6) in a 3D points cloud. This approach has the advantage to find very small edges within the scene but also builds planes based on global constrains.
Beside the development of the algorithm results of the image processing, which are really promising,
are presented. Thus the algorithm is worth to be improved by further development. The developed algorithm is able to detect very small but significant obstacles but on the other hand does not represent the scene too detailed such that the result can be illustrated accurately to a blind person.
Analysis and design of a GIS-enabled virtual public meeting space using UML for participatory municipal planning
Authors: Butt Muhammad Atif
Published: June 2021

The main aim of this research is to develop and test Web-based Public Participation Geographical Information Systems (WebPPGIS) to enable public involvement and participation in municipal planning and decision making. This objective is based on the belief that by providing citizens with access to information and data in the form of maps and visualisations they can make better informed decisions and it can immerse them into the spatial decision making process. This thesis presents a prototype implementation serving for spatially related discussions which is based on the GeoVPMS (GIS-based Virtual Public Meeting Space) model introduced by (Li et al., 2007). Moreover, a prototype has been analysed, designed and implemented using UML (Unified Model Language) approach to demonstrate a Web GIS-based architecture with utilization of various open source GIS and other OSS (Open Source Software) tools. In addition, it depicts a cost effective model of n-tier (multi-tier) Web integrated application prototype that can facilitate online public participation in municipal planning and development processes. Its components include online GIS-based participation forum as well as notification system enhance communication during spatially-related discussions in municipal planning and manage all kinds of notice among members as well as general public participants. Furthermore, the spatial data handling components used in this prototype is designed to help the public to explore the spatial contexts related to the issues under planning with and without addressing the form, whereas this contribution makes the protytope more effective and successful. In addition, the prototype is demonstrated with a scenario of public participation in spatial planning using Region of Peel's data.
Racialized Immigrants in Canada’s Changing Labour Market: An Investigation of the Effects of Precarious Work on Black Caribbean Women
Authors: Hibbert Maqueita
Published: June 2021

This research undertakes an examination of the employment opportunities and experiences of black Caribbean women in Canada, particularly within the context of the growing trend towards precarious jobs—casual, part-time and low paying—in the restructured Canadian labour market. The specific purview of this study is the labour history and employment experience of a representative group of black Caribbean women who work as Personal Support Workers in nursing homes across the Greater Toronto Area. A main concern of the study is to understand the ways in which precarious work affects these women’s settlement and integration experiences, particularly their ability to gain economic independence; this, in turn, affects a number of variables related to their, and others, perception regarding their status and place in Canada. By focusing on the case of Personal Support Workers, the study aims to shed light not only on the employment experiences of black Caribbean women in this sector but also to examine more closely the policies and employment practices that create labour market “niches” or labour “segregation” along racial and gender lines.
An Intelligent Decision Support System for Design of Brushless Direct Current Motors
Authors: Akbarzadeh Vahab
Published: June 2021

Brushless DC (BLDC) motors are among the most widely used electrical motors. Design of a BLDC motor is the most fundamental problem when dealing with the BLDC motors. This thesis presents an intelligent decision support system that can be used to design BLDC motors. A hybrid approach, that includes an object oriented paradigm using frames and procedural attachments together with a rule based mechanism, is used to build the knowledge base of the proposed architecture. The design strategy is implemented using a rule-based successive iterative method. An evolutionary fuzzy system was used to derive the modification rules of the system. The antecedent and consequent of each fuzzy modification rule was encoded as the individual of an evolutionary system. The evolutionary system evolves the set of modification rules to find a set of optimized rules. The proposed system developed design which had superior efficiency, weight and motor constant compared to design developed using the conventional design method.

Wastewater containing fats, oils and grease (FOG) is problematic in several ways: foul odors, blockage of sewer lines, interference with the proper sewage treatment operation and excess amount of FOG that can lead to certain fines for responsible wastewater generator. In this paper, the magnetic coagulation process is used to destabilize the oily wastewater emulsions while assisting with the oil floc formation. The oil/magnetic powder flocs were subsequently deposited and removed with the assistance of magnetic field. Preliminary investigations were devoted to calculations of optimal magnetic field. Preliminary investigations were devoted to calculations of optimal magnetic powder proportions were devoted to calculations of optimal magnetic powder proportions of various sizes and their oil sorption capacity. The results from the jar test confirmed the effectiveness of the magnetic coagulation procedure. It was demonstrated that the magnetic coagulation process with optimum amount of magnetic powder of 12 g/L could remove 94.2% of FOG, 96.9% of total suspended solids (TSS), and 86.7% of chemical oxygen demand (COD) on average.
Online dictionary learning techniques for financial news analysis

The investor’s sentiments can be defined an investor’s attitude and opinion towards investing in the stocks market. Investor sentiment has been traditionally regarded as a myth by classical financial theories and has received little attention by researchers prior to 1990. The standard argument was that in the highly competitive financial market, suboptimal trading behaviors, such as paying attention to sentiment signals, is unrelated to fundamental value. It has been proposed by the efficient market hypothesis (EMH) that markets are efficient in that opportunities for profit are discovered so quickly that they cease to be opportunities. The EMH effectively states that no system can continually beat the market because if that system were to become public, everyone would use it, thus negating any potential gain. From the literature, it is evident that the application of investor sentiment for evaluating market behavior is achieving broad acceptance. This paper studies the application of Soft Computing to Investor Sentiment, focusing on the dictionary learning approach. Soft computing methods and various sentiment indicators are employed to obtain sample predictions of future trends in stock market returns. This paper’s contribution is to expose the key areas where research is being undertaken, and to attempt to quantify the degree of success associated with the different research approaches.
The Reports by the Juries: A Finding Aid for a Publication From the Great Exhibition of 1851 in the Collection of the Art Gallery of Ontario
Authors: Offenbeck Jill
Published: June 2021

Produced by the Royal Commission for the Great Exhibition of 1851, the four-volume Reports by the Juries is illustrated with 154 salted paper prints from negatives by Claude-Marie Ferrier (1811-1889) and Hugh Owen (1808-1897) and document the exhibits and the Crystal Palace building. 137 copies of the Reports were produced and distributed internationally to individuals and countries that participated in the exhibition. This presentation set, which also includes the Official Descriptive and Illustrated Catalogue, the Reports to the Crown, and a presentation set of exhibition medals, belonged to Sir William Crossman (1830-1901) of the Royal Engineers. A specially designed wooden cabinet houses the set. This thesis project is divided into two parts: Part I describes the process of researching and creating the finding aid; Part II is the finding aid itself, containing ten sections addressing historical background information, photographers' biographies, photographic processes, a complete illustrated catalogue of the photographs, an analysis of the photographs, provenance, and a preliminary list of other copies of the publication in public institutions.
Development Of Framework For In-Vehicle Rear-End Collision Warning System Considering Driver Characteristics
Authors: Mehmood Atif
Published: June 2021

Rear-end collisions are one of the serious traffic safety problems. These collisions occur when the following vehicle driver is inattentive or could not judge a potential rear-end collision situation. The use of rear-end collision warning systems (RECWS) may help drivers to avoid rear-end collision. The existing systems assumed constant driver reaction time for all driver population in their design and evaluation. They also ignore variations in driver characteristics, such as age and gender.

The objectives of this thesis research are: (1) to develop reaction-time models that incorporate driver characteristics, (2) to develop a car-following simulation model that represents driver behaviour, and (3) to develop a rear-end collision warning system that accounts for driver characteristics and produces reliable collision warnings. In the human-factors study, four driver reaction-time models are developed for four different car-following scenarios: lead vehicle decelerating with normal deceleration rate, lead vehicle decelerating with emergency deceleration rate, lead vehicle stationary, and car-following acceleration regime. These models describe how the driver and situational factors affect reaction-time. The driver factors include age and gender, and the situational factors include speed and spacing between the following and lead vechiles.

The developed car-following model assumes that drivers adjust their speeds based on information of both the lead and the back vehicles. The model also assumes that the driver reaction-time varies based on driver characteristics and kinematics. The proposed model represents driver behaviour in acceleration, deceleration, and steady state regimes of the car-following scenarios. Another unique feature of the model is that it explicitly considers information on the back vehicle. The model is calibrated and validated using vehicle tracking database. The driver reaction-time models and other kinematics constraints were integrated to develop a driver-sensitive rear-end collision warning system algorithm (RECWA).

The developed car-following model is used to evaluate and validate the performance of the proposed RECWA. The results show that the proposed RECWA is functioning and producing reliable results. With further research and development, the proposed algorithm can be integrated into driving simulators or real vehicles to further evaluate and examine its benefits.
Welcoming the Stranger: The Canadian Church and the Private Sponsorship of Refugees Program
Authors: McKinlay Christine
Published: June 2021

Since the PSR program was founded in 1978, the Canadian church has portrayed a major role in the program. Many of the first sponsored refugees converted to the branch of Christianity that their sponsors practiced. Conversion was a mechanism for refugees to gain social capital and integrate into Canadian society. Today, sponsored refugees are able to tap into the rich diversity of religious communities found in urban Canadian centres and therefore are less likely to feel pressured to join their Christian sponsors in worship. This study demonstrates how the Canadian church has influenced the formation of the PSR program. The study provides an analysis of the role of Christianity in the identity formation of sponsored refugees and the inter-faith relationship between Christian sponsors and non-Christian refugees.
Examining Responsibility for Environmental Harm: Public Discourse and E-Waste Management Systems in a Developed Nation
Authors: Irani Adon Khurshed
Published: June 2021

Canadian e-waste management practices have not yet achieved high levels of environmental performance. Our methodology is based on information systems research, organization studies, and critical theory. We find evidence that – absent of strong environmental regulations – management systems designed by industry may become based on contradictory notions of responsibility (corporate, social, environmental, legal, fiscal). We posit that if such contradictions exist, the system will lack coherence, and will ultimately be unable to achieve high levels of environmental performance. Using a mixed-methods research design including critical discourse analysis and two-stage least squares regression – we offer an empirical method of environmental impact measurement - and, we conduct a comprehensive assessment of ewaste management practices in Canada in order to adequately observe and measure actual environmental benefit as impact on per capita CO2. Comments are provided with implications for further management and academic research.
