Using institutional ethnography, a sociology and critical method of inquiry used primarily in North America, this presentation discusses new forms and technologies of knowledge and governance – “forms of language, technologies of representation and communication, and text-based, objectified modes of knowledge through which local particularities are interpreted or rendered actionable in abstract, translocal terms” (McCoy, 2008: 701) on the front line of emergency medical services. I focus specifically on technologies central to health reforms that attempt to reshape how health care is delivered, experienced, and made accountable (Anantharaman, 2004; Ball, 2005; Alberta Health Services, 2008). In additional to exemplifying how institutional ethnography can be used to answer Rankin and Campbell’s (2006) call for additional research into “the social organization of information in health care and attention to the (often unintended) ways ‘such textual products may accomplish…ruling purposes but otherwise fail people and, moreover, obscure that failure’ (p. 182)” (cited in McCoy, 2008: 709), this presentation will introduce the audience to a critical approach to social inquiry that explores how knowledge is socially organized.

Conversion of agricultural biomass such as wood chips, wheat straw and forest residue for the production of fuels can help in reducing GHG emissions since they are considered as nearly carbon neutral. Around the world there is a significant amount of forest and agricultural-biomass available which could be used for the production of liquid fuels that can be blended with the petroleum-based diesel. Oxymethylene ethers (OMEs) can be derived from biomass via gasification, water-gas shift reaction and methanol production. The addition of OMEs to conventional diesel fuel has great potential to reduce soot formation during the combustion in diesel engines. Unlike methanol and dimethyl ether (DMM) which can also reduce soot formation, the physical properties of OMEs allow the use in modern diesel engines without significant change of the engines infrastructure. In this study, a detailed and data intensive process simulation model was developed to simulate all the unit operations involved in the production of OMEs from biomass. The unit operation considered include biomass drying, gasification, gas cleaning, water gas shift reaction, methanol production and OMEs synthesis. The simulation results were then utilized to conduct a detailed techno-economic assessment study of the whole biomass conversion chain to determine the most attractive pathways for OMEs production. Our recent study shows that the key parameters affecting the OMEs production are equivalence ratio, H2/CO ratio and optimal air flow. Overall, the cost of production ($/liter) of OMEs from different biomass feedstock in Alberta will be determined

Background: The increasing resistance of Gram-negative bacteria isolated from nosocomial infections and chronic wounds, such as diabetic foot ulcers has renewed research interests in the use of polymyxins in the treatment of multidrug resistant infections. The added resistance conferred by biofilm development in such infections and the absence of novel antibiotics presuppose that polymyxins are the likely drugs of choice in spite of their nephrotoxicity. The effects of PMB and PMBN have been previously assessed on planktonic bacteria isolated from various infections. Methods: This current study assessed the synergy between a PMB/PMBN and two antibiotics (ceftazidime and levofloxacin) in an attempt to develop a strategy for biofilm disruption using the Minimum Biofilm Eradication Concentration Physiology and Genetic assay (MBEC™ P & G, Innovotech Inc, Edmonton, Alberta, Canada) according to manufacturer’s instructions. Klebsiella pneumoniae (K. pneumoniae) and Proteus mirabilis (P. mirabilis) biofilms of initial broth suspensions of 108 colony forming units per mL, cultivated on the pegs of the MBEC device were challenged with 5120 µg/mL of both ceftazidime and levofloxacin in a ten-fold dilution assay and in the presence of 100 and 500 µg/mL PMB and PMBN. Results: From table of results (Table 1), it can be deduced that both ceftazidime and levofloxacin are very effective in inhibiting biofilm development (as shown by percentage inhibition (PI)) when augmented with PMB and PMBN. This is about 100-fold increase in efficacy when compared to the antibiotics used on their own. The percentage reduction (PR) in biofilm was also increased considerably when PMB and PMBN concentrations were increased to 500 µg/mL. PMB was more effective than its less antibacterial derivative PMBN. Levofloxacin was also found to be more effective than ceftazidime when combined with both PMB and PMBN due to its enhanced cell-membrane permeability and as an anti-DNA replication uncoupling agent. Conclusion: The above results indicate that the synergy between antibiotics and cell membrane permeabilising agents may provide alternate strategies towards biofilm eradication

Pygmy Shrews in North America have variously been considered to be one species (Sorex hoyi) or two species (S. hoyi and S. thompsoni). Currently, only S. hoyi is recognized. In this study, we examine mitochondrial DNA sequence data for the cytochrome b gene to evaluate the level of differentiation and phylogeographic relationships among eleven samples of Pygmy Shrews from across Canada. Pygmy Shrews from eastern Canada (i.e., Ontario, Quebec, New Brunswick, Nova Scotia, and Prince Edward Island) are distinct from Pygmy Shrews from western Canada (Alberta, Yukon) and Alaska. The average level of sequence divergence between these clades (3.3%) falls within the range of values for other recognized pairs of sister species of shrews. A molecular clock based on third position transversion substitutions suggests that these two lineages diverged between 0.44 and 1.67 million years ago. These molecular phylogenetic data. combined with a reinterpretation of previously published morphological data, are suggestive of separate species status for S. hoyi and S. thompsoni as has been previously argued by others. Further analysis of specimens from geographically intermediate areas (e.g., Manitoba. northern Ontario) is required to determine if there is secondary contact and/or introgression between these two putative species.

School choice-the movement towards increased parental and student control over public education-has been endorsed extensively as a means of revitalizing and improving public schools. Part of this movement is the concept of charter schools, which have expanded rapidly in the United States and around the globe. In stark contrast, Canadians have remained relatively content with current educational arrangements; only 13 charter schools currently exist in Canada, all in the province of Alberta. This study sought to identify why charter schools have failed to situate themselves in Canadian education. The study used an agenda setting framework to determine the salience of charter schools as a public issue in three provinces: Alberta, British Columbia, and Ontario. Results largely indicate that over the past 18 years, charter schools have gradually declined as a salient issue. Additional discussion concerning the unique characteristics of Canadian education highlights factors that appear to discourage the expansion of such schools. However, although charter schools do not appear to be a current issue for Canadians, they may still emerge in the future, as parents and teachers continue to seek new ways of improving educational outcomes. Thus, although the impact of charter schools on public education has been minimal to date, they provide an illuminating lens towards better understanding educational reform and policy, as well as the fundamental values that shape education in Canada.

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.

Plutella xylostella (diamondback moth, DBM) is a globally distributed Lepidopteran that feeds and oviposits almost exclusively on plants in the Brassicaceae family. DBM disperses from the southern United States and Mexico into Canada in the spring and summer. Establishment of DBM in Ontario is partially dependent upon the quantity and quality of host plants available and the preference of DBM for different hosts. Host plants include many crops such as broccoli, canola and cabbage, as well as landscape ornamentals and wild plants. It has previously been established that DBM are attracted to host plants by chemicals, specifically glucosinolates. I examined the preference of DBM among crop, wild and ornamental host plant species and how preference varies with insect life stage (3rd and 4th instar larvae and adults). Experiments included exposing DBM larvae from five populations coming from different locations in Canada to six Brassicaceae species and evaluating the preferences and weight gain over one hour. Then adult females were exposed to these same plant species and their oviposition preferences were examined. Populations from Alberta, Saskatchewan and Ontario were compared to assess differences in preference associated with geographic region or species of host plant. The ultimate goal of my study was to understand the potential of various Brassicaceae species to act as reservoirs to sustain and promote population growth of DBM, as well as sinks that may decrease DBM abundance. Results showed that garden cress (Lepidium sativum) was highly preferred over other species (wintercress, black mustard, aubretia, broccoli and ornamental kale) for both food and oviposition sources. Previous studies report that garden cress contains saponins, chemicals shown to be toxic to developing DBM larvae, however no studies have yet shown a preference for garden cress. These results provide information on a novel host plant with the potential to control DBM population growth. No difference in preferences was found among populations of DBM from various sources in Canada.

A letter from Cal Cavendish of Cavenidish Country in Calgary, Alberta. Cavendish has written a song about former prime minister R. Honourable John Diefenbaker. He has included the lyrics to his song. A few of the lyrics: "...Well it took a little while, but he reached his destiny, He was right, he was wrong, but he ran this big country. He didn't waste much time when he had a job to do, He worked the House of Commons like a prairie thrashing crew. Good old John, we heard you John, when a man got paid for the job when the job got done."

The Johns-Manville Company was founded in 1901with the merging of the H.W. Johns Manufacturing Company and the Manville Covering Company. Both companies made building materials using asbestos. The new company was based in New York, New York, and made products such as insulation and roofing materials, automotive sheet packing for cylinders, asbestos/cement, acoustical and magnesia products. Significant restructuring has occurred over the years as the company shifted from production of asbestos products to other types of building materials, such as fibre glass and forest products. Since 2001, the Johns-Manville Company has been owned by Berkshire Hathaway. The company began operations in Canada in 1918 in Asbestos, Quebec, where the Jeffrey Asbestos Mine was located. A Canadian plant opened in Port Union, Scarborough Township, in 1956, and another in North Bay, Ontario, in 1957. Both of these plants have since closed. The company currently has two plants in Canada, in Innisfail, Alberta, and Cornwall, Ontario.
