An instrumental case study was conducted to explore the perspective of recent graduates from a Greater Toronto Area community college experience in relation to Workplace Essential Skills (WES). Five participants who graduated from a business school within the last 4 years were interviewed twice over a 4-month period to gain a deeper understanding of this relationship. This qualitative approach used semi-structured interviews to elicit stories about their experiences, their relationships in school, and the development of skills that were useful in the workplace. The analysis of data involved the 3-step coding process of open, axial, and selective coding consistent with the approach used by Neuman (2006). The analysis revealed that the overall experience of attending college contributed to the learning that took place. The participants gave greater significance to the life experience in learning WES and the networks associated with learning than the formal aspects of education. It is also important to acknowledge that the research identified a significant opportunity for educators’ to positively impact the learning experience.

Part I: Ultra-trace determination of vanadium in lake sediments: a performance comparison using O2, N20, and NH3 as reaction gases in ICP-DRC-MS Thermal ion-molecule reactions, targeting removal of specific spectroscopic interference problems, have become a powerful tool for method development in quadrupole based inductively coupled plasma mass spectrometry (ICP-MS) applications. A study was conducted to develop an accurate method for the determination of vanadium in lake sediment samples by ICP-MS, coupled with a dynamic reaction cell (DRC), using two differenvchemical resolution strategies: a) direct removal of interfering C10+ and b) vanadium oxidation to VO+. The performance of three reaction gases that are suitable for handling vanadium interference in the dynamic reaction cell was systematically studied and evaluated: ammonia for C10+ removal and oxygen and nitrous oxide for oxidation. Although it was able to produce comparable results for vanadium to those using oxygen and nitrous oxide, NH3 did not completely eliminate a matrix effect, caused by the presence of chloride, and required large scale dilutions (and a concomitant increase in variance) when the sample and/or the digestion medium contained large amounts of chloride. Among the three candidate reaction gases at their optimized Eonditions, creation of VO+ with oxygen gas delivered the best analyte sensitivity and the lowest detection limit (2.7 ng L-1). Vanadium results obtained from fourteen lake sediment samples and a certified reference material (CRM031-040-1), using two different analytelinterference separation strategies, suggested that the vanadium mono-oxidation offers advantageous performance over the conventional method using NH3 for ultra-trace vanadium determination by ICP-DRC-MS and can be readily employed in relevant environmental chemistry applications that deal with ultra-trace contaminants.Part II: Validation of a modified oxidation approach for the quantification of total arsenic and selenium in complex environmental matrices Spectroscopic interference problems of arsenic and selenium in ICP-MS practices were investigated in detail. Preliminary literature review suggested that oxygen could serve as an effective candidate reaction gas for analysis of the two elements in dynamic reaction cell coupled ICP-MS. An accurate method was developed for the determination of As and Se in complex environmental samples, based on a series of modifications on an oxidation approach for As and Se previously reported. Rhodium was used as internal standard in this study to help minimize non-spectral interferences such as instrumental drift. Using an oxygen gas flow slightly higher than 0.5 mL min-I, arsenic is converted to 75 AS160+ ion in an efficient manner whereas a potentially interfering ion, 91Zr+, is completely removed. Instead of using the most abundant Se isotope, 80Se, selenium was determined by a second most abundant isotope, 78Se, in the form of 78Se160. Upon careful selection of oxygen gas flow rate and optimization ofRPq value, previous isobaric threats caused by Zr and Mo were reduced to background levels whereas another potential atomic isobar, 96Ru+, became completely harmless to the new selenium analyte. The new method underwent a strict validation procedure where the recovery of a suitable certified reference material was examined and the obtained sample data were compared with those produced by a credible external laboratory who analyzed the same set of samples using a standardized HG-ICP-AES method. The validation results were satisfactory. The resultant limits of detection for arsenic and selenium were 5 ng L-1 and 60 ng L-1, respectively.

Typical employment options for people with developmental disabilities are insufficient. Most employment opportunities that are community-based provide typical workplace and geographical inclusion but tend not to support social inclusion and "belonging". This study explored the innovative employment alternative of social businesses and considered this form of employment for persons with a developmental disability as a viable avenue for meaningful work and social inclusion. A total of six business partners with a developmental disability were interviewed; two partners from three separate worker owned businesses. The partners' descriptions of their job and their workplace composed the interpretative findings. The social businesses provided an avenue for this group of people who tend to be segregated in isolated workshops or marginalized in mainstream work environments and who feel a sense of being "outsiders" to participate in meaningful work in community settings. This group of partners described their job as authentic "work" and discussed the many skills and the work ethic learned from their employment opportunity. In addition to the instrumental aspects of the job, the partners also discussed the group autonomy and self-determination of being their own "bosses". The partners confidently expressed feeling valued, understood in the context of others with similar life experiences, attached to the workplace and connected to a larger community as important outcomes of their businesses. These criteria of social inclusion (Hall, 2010) were complemented by teamwork, friendship and ultimately, with a feeling of being genuine "insiders". Replication of this innovative employment model would be recommended for groups of marginalized people with DD in other geographic areas.

The St. Catharines and District Labour Council was founded in May 1957 by unionized workers from St. Catharines, Thorold, Merritton, Port Dalhousie and Grimsby. They sought to improve the social and economic welfare of workers; promote the organization of workers into unions for their mutual benefit, regardless of race, creed, colour, or national origin; encourage the sale of union-made goods and services; promote worker education; provide workers with a voice in politics; and safeguard the democratic nature of the labour movement. The Council, affiliated with both the Canadian Labour Congress and the Ontario Federation of Labour, was instrumental in assisting local workers with their labour disputes, including Canadian Pulp and Paper workers at Abitibi Provincial Paper in Thorold [1975-76], and Gallaher Paper [1999], workers at the St. Catharines Eaton’s store [1985], as well as smaller disputes such as that between the part-time secretarial staff and the Welland County Roman Catholic Separate School Board [1972] and workers of the Skyway Lumber Company [1972]. The Council also assisted the community at large by offering a Community Counseling Service [1971-1976] to help citizens with issues concerning various government agencies, social services and Acts, such as the Vacation Pay Act, Landlord and Tenant Act, Employment Standards Act, unemployment insurance claims and workman’s compensation claims. Other projects that the Council organized included an annual Education Institute [1958-1965] and the annual publication of Labour Review, a summary of the Council’s past year. The Labour Council continued to operate until 2010, when several local Labour Councils merged to form the Niagara Regional Labour Council.

Donald J. P. Ziraldo, C.M., BSc., LLD was born in St. Catharines, Ontario on October 13, 1948 to Fredrick and Irma (Schiratti) Ziraldo. He graduated Denis Morris High School in St. Catharines in 1967, and received his B.Sc. in Agriculture at the University of Guelph in 1971. In 1974, Ziraldo was running Ziraldo Nurseries when he met Austrian born schoolteacher, chemist and winemaker Karl J. Kaiser. They realized that there was a gap in the premium varietal wine market and decided to plant a premium traditional European variety of grape vine species, the Vitis vinifera. This was an innovation in the Niagara region because the current wine producers were not using premium European grapes at the time. Ziraldo and Kaiser founded and then formally incorporated Inniskillin Wines Inc. in Niagara-on-the-Lake, Ontario on July 31, 1975. Ziraldo successfully lobbied General George Kitching, CEO of the LCBO, for a winery license. In 1975, Kitching granted him a winery license, the first in Ontario since Prohibition ended. From the beginning, there was a division of labour where Kaiser focused on the winemaking and Ziraldo focused on the marketing and promotion of the wines. Ziraldo also became president of the company. Ziraldo and Kaiser worked on improving their winemaking techniques and promoting their products and company. Ziraldo has been called ‘one of the founding fathers of the Canadian wine industry’, and it is widely acknowledged that both men played a large role in the success and growth of the Canadian wine industry. Together they pioneered the estate winery movement in Canada. A major turning point Inniskillin came in 1984 when Karl Kaiser successfully harvested the first Icewine crop from frozen grapes on the vine and bottled Eiswein Vidal (Icewine). In 1990, Inniskillin received worldwide recognition for this Icewine when their 1989 Vidal Icewine won the most prestigious award in the wine world, the Grand Prix d’Honneur, given at Vinexpo in France. This victory has been called ‘the award heard round the world’ and it launched Inniskillin into the international wine arena. At the same time, this helped lift the profile of Canadian wines in general. Inniskillin not only became Canada’s leading producer of Icewine, but it also became known for producing ‘one of the world’s great wines’. After the 1990 award, Ziraldo began a major public relations campaign to promote Inniskillin and build Icewine into a worldwide brand. He travelled broadly every year to promote the brand and products and networked extensively with politicians, celebrities, chefs, sommeliers, etc. To ensure worldwide and long-term success, Ziraldo introduced Icewine to Asia and the United States which were new markets. He developed a new Icewine glass with George Riedel. Tony Aspler has called Ziraldo ‘Canada’s Wine Ambassador’. Ziraldo was President of Inniskillin Wines Inc. (Niagara) from 1975 to 2006. In 1992, Inniskillin merged with Cartier Wines, and in 1993 Cartier Inniskillin Vintners Inc. merged with T.G. Bright & Co. Limited, forming the new company Vincor International Inc. Inniskillin wines was now a subsidiary of Vincor. Ziraldo became a Director at Vincor International Inc. from 1993 to 2004. From 1989 to the mid 1990s, Ziraldo also became President of Inniskillin Napa, in Napa Valley, California. Inniskillin purchased Napa Valley vineyards and produced wines under the Terra label. In 1994, Ziraldo set up a subsidiary estate winery of Inniskillin in Oliver, British Columbia which was called Inniskillin Okanagan Vineyards Inc. He became President of the winery. This started as a partnership between Inniskillin and the local Inkameep Indian Band in the Okanagan. In 2006, Ziraldo left Inniskillin and since that time he has been involved in other Icewine related ventures such as running Ziraldo Estate Winery and producing Ziraldo Riesling Icewine 2007. He also is in partnership with the Niagara based Equifera Estate Winery to produce Equifera Icewine. His most recent projects include planting Picolit grapes in his parent’s hometown, in a project called Picolit Di Fagagna and becoming Managing Director of the Senhora Do Convento Port Winery in Portugal. Donald Ziraldo was instrumental in the creation of the Vintners Quality Alliance (VQA) in Ontario and was its founding Chair from 1988-1995. The VQA was established as a regulatory and appellation system which secured the quality and origin of Canadian wines made under this system. The VQA designation and bottle label gave the consumer confidence that the wines they were purchasing were 100% local products. The VQA system was set up first in Ontario and then in British Columbia.

Estelle Cuffe Hawley (1894-1995) was an educator, businesswoman and politician, who became the first woman alderman on the St. Catharines City Council. She began her career as a teacher in Peterborough in 1913, and later taught in St. Catharines at Connaught School and St. Paul’s Ward School, where she served as Principal for six years. In 1928-29, she worked as an exchange teacher in Edmonton, Alberta. This would be Estelle’s last year in the teaching profession. She moved back to St. Catharines in 1930 and began a career in business, as an employee of Sun Life Assurance Co. She remained in this profession until around 1952. It was during this period that she became very active in the community and local politics. In 1934 she was elected to the St. Catharines Board of Education, where she advocated for the improvement of teachers’ salaries, the introduction of nursing services in schools, and the inclusion of music in the curriculum. She served as a member of the school board until 1937. The following year, she became the first woman elected to the St. Catharines City Council. As an alderman, she worked to improve the community's social welfare services, serving consecutively as chairman of all committees. She established comprehensive health services (including medical, dental and nursing), in the public, separate and secondary schools of St. Catharines, the first program of its kind in Canada. She was also instrumental in establishing minimum housing standards and engaging the public in local government by arranging a series of lectures by city officials. She remained a member of City Council until 1943. The following year she campaigned unsuccessfully for the mayoralty. In 1953 she married Hubert Hawley and moved to Orillia. She continued to remain active in the community, serving as President of the Ontario Recreation Association from 1950-1953, and editor of their Bulletin from 1955-1961. During the 1960s, she worked with various groups, including the Voice of Women, the Mental Health Association and the Freedom from Hunger Campaign. In addition to this work, Estelle wrote poetry and short stories, some of which were published in the Peterborough Review, the Globe and Mail and the Canadian Churchman. Some of her short stories (often about her childhood experiences) were broadcast on the CBC, as well as her experiences as a Town Councillor (under the pseudonym Rebecca Johnson in 1961). She also broadcast a segment that was part of a series called “Winning the Peace” in April 1944. Estelle was a sought-after public speaker, speaking on topics such as peace, democracy, citizenship, education, and women’s rights. In 1976, Brock University conferred an honorary Doctor of Law degree to Estelle for her leadership as an educator, businesswoman and a stateswoman. Her husband Hubert died that same year, and Estelle subsequently moved to Mississauga. With the assistance of an Ontario Heritage Foundation grant, she began work on her memoir. She later moved back to Orillia and died there in 1995, at the age of 101.

William Hamilton Merritt (1793-1862) was a soldier, merchant, and politician who was instrumental in the promotion and development of the Welland Canal. After serving with the Lincoln militia during the War of 1812, Merritt became a merchant in St. Catharines, and purchased some land on Twelve Mile Creek on which he ran a sawmill and constructed a grist mill. He initially envisioned a canal between the Welland River and Twelve Mile Creek, which evolved into a plan to link Lake Ontario and Lake Erie. This would enable goods from western Canada to be conveniently shipped to Montreal and Great Britain through the St. Lawrence, while bypassing the Niagara portage. His plan met with opposition for financial and political reasons, as well as from those along the Niagara portage whose businesses would suffer if the canal were built. Despite this opposition, the Welland Canal Company was chartered by the Upper Canadian assembly in January, 1824. Construction on the canal began later that year, and was completed in 1829.

John Cronyn (1827-1898) emigrated to Canada from Ireland in 1837. He studied medicine at the University of Toronto, but was not granted his degree upon completion of the requirements. He refused to take the test oaths meant to exclude Catholics from the profession and was not granted his degree until several years later, when the discriminatory laws were rescinded. In 1850, he married Elizabeth Willoughby of Toronto. They settled in Fort Erie and he established a successful medical practice there. He was active in the community, serving as Superintendent of schools and one term as Reeve. In 1859 he relocated to Buffalo and continued to practice medicine there. Cronyn was instrumental in the establishment of a medical department at Niagara University, where he was a professor and president of faculty. Nelson Forsyth was the son of William Forsyth (1771-1841), a prominent businessman in Niagara who owned and operated the Pavilion Hotel (later known as Forsyth’s Inn). Nelson was also a businessman and lived in Fort Erie with his wife Archange Warren.

The Woodruff Family Collection: From the time the Woodruff Family came to Canada from the United States in 1795, they took an active role in the forming of their communities both in a civic and social manner. This is evident through the documents contained in this collection. The Woodruffs played an active role in the battles fought in Upper Canada and they were an integral part of the Village of St. Davids. They were educated, business-minded and socially engaged. They accumulated much of their fortune through land dealings. Much of this collection focuses on Samuel DeVeaux Woodruff who was principally a businessman. His dedication to his work is shown through his numerous undertakings. He made his mark on the Niagara Peninsula through his work on the railways, roads, marsh land revisions, canals and the paper industry. He was also involved with the founding of the Long Point Company and he took control of building DeVeaux Hall down to the last detail. His offspring inherited his work ethic and his business acumen. The people who married into the Woodruff Family also possessed key social, political and business ties. Anne and Margaret Clement were from a staunch Loyalist background. Samuel Zimmerman was instrumental to the founding of Niagara Falls and Judge Samuel DeVeaux left behind a legacy for poor and homeless boys in Niagara Falls, New York. The Woodruff Family undoubtedly left a mark on the Niagara Peninsula. This collection brings to light many endeavours of the family and their varied contributions.

John Butler (1728-1796) was originally from Connecticut but settled with his family in the Mohawk valley of New York around 1742. His father was a Captain in the British army and well acquainted with William Johnson (superintendent of Northern Indians). Butler impressed Johnson with his aptitude for Indian languages and diplomacy. He began to work with Johnson in 1755, and received several promotions in the department, until his apparent retirement in the early 1770s. At the onset of the Revolutionary War in 1775, Butler relocated to Canada to join the British forces, settling in Niagara. During the War, Butler was instrumental in maintaining the alliance with the Indians. After the War, Butler became prominent in local affairs in Niagara, but failed to secure any important offices when the province of Upper Canada was formed in 1792. In an effort to recoup some of the financial losses his family suffered during the War, Butler illegally attempted to supply trade goods to the Indian department with his son Andrew, his nephew Walter Butler Sheehan, and Samuel Street, a Niagara merchant.

Past research has identified the importance of the relationship between teacher candidates and their associate teachers during field experiences. Through the research questions that framed the study, I sought to contribute to a growing understanding of how the associate teacher-teacher candidate relationship develops from the perspective of teacher candidates. Using an interpretive lens, I explored the associate teacher-teacher candidate relationships of 5 teacher candidates at a mid-sized university in Southern Ontario. In this instrumental multicase study, the 5 participants described 13 pairs of relationships with associate teachers who modeled varying practices. The qualitative data surrounding these case relationships were collected through a focus group and semistructured interviews. Participants’ responses were analyzed using axial coding and constant comparative analysis. Participants identified feedback, guidance, support, genuine interactions, and relationship dynamics as central to successful field experiences. Participants also suggested that associate teachers might be better supported in their role if they were offered increased professional development from the faculties of education that organize the field experiences. The findings documented offer a fresh perspective of the role of the associate teacher in successful teacher education programs, particularly as experienced by the 5 participants.

The purpose of this research study was to determine if the instructional model, Teaching Games for Understanding (TGfU), would allow for the successful teaching of sport to disengaged female students in Physical Education (PE) classes. An instrumental case study research design was used to determine grade nine female students’ experiences with TGfU, the factors of TGfU that facilitated their engagement, and the ways in which these students resisted engaging in TGfU. Data was collected through a pre and post TGfU unit focus group, participant observation, in-depth interviews, and researcher reflections. Results showed that TGfU caused an increase in the participants’ engagement in PE physically, mentally, and socially/emotionally. Future researchers could structure their entire study holistically and should examine TGfU’s impact on student engagement over the course of an entire semester. Subsequent studies should moreover examine the presence of disengagement within physically skilled students in PE.
