 Between life and the underground : a study of photography found in Rolling Stone magazine from 1967 to 1972.
Between life and the underground : a study of photography found in Rolling Stone magazine from 1967 to 1972.
In order to consider what the photography used within Rolling Stone magazine contributes to the history of photojournalism, Between Life and the Underground analyzes the aesthetic of the photography and conceptual layouts produced within the magazine. This study looks specifically at the period of 1967 to 1972, a time when mainstream publications like Life magazine ceased production and when over 500 underground publications were piloted. A comparative analysis of the design, economics, and production of both Rolling Stone and the underground publication the Berkeley Barb traces the influence that the underground had on the aesthetic of Rolling Stone’s photography and layout. The role that cover photography played in perpetuating the identity that Rolling Stone wanted to embody is also investigated. The influence that New Journalism had on the production of photojournalism at Life and Rolling Stone is also considered—framed around a comparison of the photographic coverage of the Woodstock Festival of 1969 and the police riots at the Democratic National Convention of 1968. This study concludes that the underground press cultivated a new photographic aesthetic and conceptual technique for laying out photographs which adhered to the ideals of the 1960s—namely informality, which Rolling Stone then adapted to create a profitable magazine.
 Children's and parents' thoughts and feelings regarding nature in two types of locations:  comparisons and  implications
Children's and parents' thoughts and feelings regarding nature in two types of locations: comparisons and implications
This study examines the nature thoughts and feelings of 6 - 12 year-old children and their parents living in mountainous and city regions. It asks whether location and parental influences play roles in children's responses. Hypotheses assumed that participants in mountainous locations would be more connected with nature and that children's and parents' nature thoughts would correlate. Using mix-methods, surveys were distributed to 192 participants. Results illustrated that children in mountainous regions displayed more emotion words while children in the city displayed more descriptive words. No significant differences were found between parents. Compared to the urban sample, participants in mountainous regions felt that their environment was more a part of nature. Lastly, descriptive and total number of words correlated for parents and children. Recommendations include suggestions for curriculum design and childhood experiences. Parents, educators, and policy-makers should provide more unstructured outdoor play opportunities.
 Clinging to a knife’s edge: the Live-in Caregiver Program
Clinging to a knife’s edge: the Live-in Caregiver Program
Since the 1900s, Canada has heavily relied on foreign domestic workers. This program has evolved over the years into what is currently known as the Live-in Caregiver Program (LCP). It is rooted in our colonial history and has reproduced power imbalances between employers and caregivers. Challenging dominance is a difficult task given that immigration policies perpetuate inequalities through the denial of social, economic and political rights to caregivers. I selected this topic based on my experiences as a live-in caregiver with this program. This study uses anti-colonialism and feminist thought to examine the experiences of three former LCP workers. Through narrative interviewing, the findings indicate that the live-in requirement of the LCP has contributed to the abuse, exploitation and marginalization of these caregivers. The study concludes with a discussion of the ways in which the structure of the program can be modified to prevent further exploitation and human rights violations.
 Configurable simultaneously single-threaded (multi-)engine processor
Configurable simultaneously single-threaded (multi-)engine processor
As the multi-core computing era continues to progress, the need to increase single- thread performance, throughput, and seemingly adapt to thread-level parallelism (TLP) remain important issues. Though the number of cores on each processor continues to increase, expected performance gains have lagged. Accordingly, com- puting systems often include Simultaneously Multi-Threaded (SMT) processors as a compromise between sequential and parallel performance on a single core. These processors effectively improve the throughput and utilization of a core, however often at the expense of single-thread performance as threads per core scale. Accordingly, applications which require higher single-thread performance must often resort to single-thread core multi-processor systems which incur additional area overhead and power dissipation. In attempts to improve single- and multi-thread core efficiency, this work introduces the concept of a Configurable Simultaneously Single-Threaded (Multi-)Engine Processor (ConSSTEP). ConSSTEP is a nuanced approach to multi- threaded processors, achieving performance gains and energy efficiency by invoking low overhead reconfigurable properties with full software compatibility. Experimen- tal results demonstrate that ConSSTEP is able to increase single-thread Instruc- tions Per Cycle (IPC) up to 1.39x and 2.4x for 2-thread and 4-thread workloads, respectively, improving throughput and providing up to 2x energy efficiency when compared to a conventional SMT processor.
 Crashworthiness of vehicle-to-pole collisions using a hybrid III 3-year-old child dummy
Crashworthiness of vehicle-to-pole collisions using a hybrid III 3-year-old child dummy
To date, statistics indicate that motor vehicle crashes are one of the leading causes of death and injury for children despite improved crashworthiness of vehicles and child restraint systems, since children are at risk for devastating head and neck injuries due to their fragile physiology. Thus, this thesis focused on minimizing child injuries experienced during frontal vehicle-to-pole collisions by improving on the safety and energy absorption of existing traffic pole structures. A finite element computer model, using LS-DYNA software, was used to simulate crash events in order to determine the influence of pole structural and material characteristics on the injury parameters of a 3-year-old child dummy occupant. It was concluded that the anchored base support, and the embedded pole in soil systems provide desirable crashworthy results. In addition, it is recommended to mandate traffic protection devices in all areas with poor energy absorbing characteristics that resemble non-deformable objects.
 Culturally safe care & the Ontario midwifery model: exploring the challenges of serving uninsured immigrant clients
Culturally safe care & the Ontario midwifery model: exploring the challenges of serving uninsured immigrant clients
Immigrant women’s healthcare has been one of the major areas of research in the literature on settlement in Ontario, but little research exists on the relationship between immigrant women and their healthcare providers, and even less that is from the perspective of the healthcare provider. This study used semi-structured interviews with 10 midwives who serve uninsured immigrant clientele in order to understand how they navigate challenges to provide culturally safe care. Discourse analysis revealed that participants discussed barriers that were both logistical and conceptual in nature when providing care to uninsured immigrant clients. Midwives indicated that logistical barriers and fear of providing insufficient culturally safe care were factors that made practices more reluctant to take on uninsured immigrant clients. Their discussion of culturally safe care was informed by the Ontario midwifery model, but their strategies for delivering culturally safe care often involved a renegotiation of this model.
 Current source converter-based offshore wind farm: configuration, modulation, and control
Current source converter-based offshore wind farm: configuration, modulation, and control
Offshore wind power is attracting increased attention because of considerable wind resources, higher and steadier wind speeds, and smaller environmental impact. Recently, a current source converter (CSC)-based series-connected configuration is proposed and it is considered a promising solution for offshore wind farms as the offshore substation used in existing systems can be eliminated. However, such a CSC-based configuration has disadvantages in terms of size and weight, dynamic performance, cost, reliability, and efficiency. Therefore, this thesis proposes new configurations, modulation scheme, and control schemes to improve the performance of the CSC-based offshore wind farm. First, a new configuration is proposed for the CSC-based offshore wind farm. Compared with existing CSC-based configurations, the new one is expected to be smaller in size and weight. Second, conventional space vector modulation (SVM) with fast dynamic response cannot be used for grid-side CSCs because of its high-magnitude low-order harmonics. To solve this issue, an advanced SVM with superior low-order harmonics performance is proposed. Third, power balancing among series-connected CSCs is an important consideration for system reliability. The possible imbalance of power is investigated and quantitatively defined. A power balancing scheme is proposed, based on which equal power distribution among CSCs is ensured. Fourth, to lower the system insulation requirement of the CSC-based configuration, a bipolar operation is investigated. Compared with monopolar mode, bipolar mode gives lower insulation level, thus contributing to the system in terms of lower cost and higher reliability for a given power rating. In addition, an optimal dc-link current control giving higher efficiency is proposed for the bipolar system. Fifth, an optimized control strategy with reduced cost and improved efficiency is proposed for the CSC-based offshore wind farm. The nominal number of onshore CSCs is optimized, which reduces the cost on power converters. And an optimized bypass operation is introduced to onshore CSCs, which improves the efficiency of the system. Finally, simulation and experimental results are provided to verify the performance of the proposed configuration, modulation scheme, and control schemes.
 Data migration: relational RDBMS to non-relational NoSQL
Data migration: relational RDBMS to non-relational NoSQL
As a part of achieving specific targets, business decision making involves processing and analyzing large volumes of data that leads to growing enterprise databases day by day. Considering the size and complexity of the databases used in today’s enterprises, it is a major challenge for enterprises to re-engineering their applications that can handle large amounts of data. Compared to traditional relational databases, non-relational NoSQL databases are better suited for dynamic provisioning, horizontal scaling, significant performance, distributed architecture and developer agility benefits. Based on the concept of Object Relational Mapping (ORM) and traditional ETL data migration technique this thesis proposes a methodology for migrating data from RDBMS to NoSQL. The performance of the proposed solution is evaluated through a comparative analysis of RDBMS and NoSQL implementations based on query performance evaluation, query structure and developmental agility.
 Development of a web-based collaborative PPGIS to support municipal planning.
Development of a web-based collaborative PPGIS to support municipal planning.
The use of computing technologies to support workflows related to the planning and development of a municipality dates back to the late 1950s. The main boosts of computing technologies and applications, Geographic Information System (GIS) and Geographic Information Technology (GIT), in relation to a planning and decision-making context, became evident when the use of Public Participation GIS (PPGIS) started in the 1980s. Collaboration is an important part of many tasks involving people from different organizations, in which maps often play a central role in informing and improving debates and facilitating the decision-making process. It allows diverse stakeholders to share and view maps or spatial images interactively over the Web in real-time, among other platforms. The geospatial collaboration technology not only provides an effective solution to decision makers, but also facilitates scientific and public debates with real-time geospatial information. More recently, some efforts have been made using open map services to develop simple map-sharing applications. However, little has been done on designing and developing such online open source tools in the context of municipal planning and management. Further, a literature review indicates the lack of scientific publications on empirical studies of their practical applications. Web-based PPGIS applications, among others, have now been widely recognized as an efficient and integral part of sound planning and development processes to support public participation. However, GIS alone cannot make the planning process more participative. Demands for Web-based PPGIS tools, integrated with other information and computer-supported cooperative work (CSCW) tools, have rapidly become increasingly important for supporting collaborative participation during a decision-making process. Therefore, the establishment of public participation in GIS-based applications is an optimistic step taken by the researchers that are progressively working on municipal planning projects that incorporate public participation. The main aim of this research is to provide a Collaborative PPGIS (Co-PPGIS) to enhance public participation in municipal planning related workflows. A research prototype has been developed and its usability is evaluated by adopting the evaluation criteria for the research prototype, as only proper testing will demonstrate whether the prototype is usable or the Co-PPGIS design framework is successful in meeting end-users’ requirements.
 Do development permit systems inherently facilitate intensification objectives?
Do development permit systems inherently facilitate intensification objectives?
The purpose of this paper is to determine whether Development Permit Systems passively achieve policy-related intensification objectives in addition to explicit provisions. The methodology includes a brief history and review of applicable laws to explain how Development Permit Systems were created in Ontario. An overview of the Town of Gananoque policy documents is discussed and compared to Growth Plan intensification objectives. Development Permit System benefits and disadvantages are compared to Growth Plan intensification policies and Gananoque Official Plan residential policies to determine whether Development Permit Systems inherently achieve Growth Plan objectives. The key finding is that Development Permit Systems somewhat inherently achieve residential intensification policies, depending on whether the intensification provisions are included within the DPS to begin with and whether there are intensification policies included in the associated Official Plan policies.
 Effects of Road De-Icing Salts on Two Amphibian Species, Rana Sylvatica and Rana Pipiens, and Their Trematode Parasites
Effects of Road De-Icing Salts on Two Amphibian Species, Rana Sylvatica and Rana Pipiens, and Their Trematode Parasites
With ongoing amphibian declines, it is essential to determine possible contributors such as diseases and environmental contaminants that may increase susceptibility. A potential contaminant is road salt (mainly NaCl), which leaches into aquatic environments. I examined whether road salts make larval amphibians (tadpoles) more susceptible to trematode parasite infection, and also how these affect free-living trematode infectious stages (cercariae). I exposed Rana sylvatica (wood frogs) and R. pipiens (northern leopard frogs) to control, medium (400 mg/L), and high salt (800 mg/L) treatments, and then to trematodes. High salt tended to reduce wood frog anti-parasite behaviour and resistance to infection but the opposite was seen for R. pipiens, although these tadpoles had elevated lymphocyte counts in high salinity. Trematodes were differentially affected by increased salinities. The results suggest that host-parasite-environment interactions are complex, with species differentially affected by contaminants, which may lead to community shifts in predominant hosts and parasite species.
 Empower women:  examining the feasibility of using a  360°  digital-first magazine as a health teaching  and knowledge translation tool for millennial women
Empower women: examining the feasibility of using a 360° digital-first magazine as a health teaching and knowledge translation tool for millennial women
Worldwide, women experience inequities in health due to unfair relations of power and control over their lives (Women and Gender Equity Knowledge Network, 2007). This is especially true in the area of women’s health (Husoy-Onarheim, Iversen, & Bloom, 2016; Perry, 2012). As healthcare shifts to a health promotion model, women are being empowered through the facilitation of health literacy and informed decision-making (Wuest, Merritt-Gray, Berman, & Ford-Gilboe, 2002; Leaffer & Mickelberg, 2006). In recent years, digital media has become one of the primary ways millennial women access health information (Allison, et al., 2012). Yet there are limited resources that are accurate, engaging and easy to understand (Allison, et al., 2012; Calvillo, Roman, & Roa, 2013). This project examined the feasibility of using a digital magazine as a health teaching and knowledge translation tool for millennial Canadian women. The result of this project was a pilot 360° magazine experience designed to engage millennial women in discussions about taboo health topics.
