Different strains of rainbow trout (Salmo gairdneri), Ten Sleep, Sand Creek, Beitey, Shepherd-of-the-Hills, New Zealand, Fish Lake- Desmet, Desmet, were compared for survival to the creel, growth and catchability after being stocked in a fluctuating 80 ha Utah reservoir . Fish were stocked in the spring and fall as fingerlings and monitored by creel censusing, gill netting and electrofishing. Fish were tagged with coded wire snout tags prior to stocking . An angler opinion survey was conducted to determine angler satisfaction with numbers and size of fish caught. Regardless of strain, spring stocking was superior to fall stocking in survival to the creel. In the spring 78 stocking the Ten Sleep strain had the highest survival to the creel (33.7 percent), followed in order by Shepherd-of-the-Hills (11.0 percent), Beitey (5.5 percent), Sand Creek (5.4 percent), New Zealand (4.1 percent), and Fish Lake-Desmet (2 .9 percent). In the spring 79 stocking the Shepherd-of-the- Hills strain had the highest survival to the creel (7 .6 percent), followed in order by the Sand Creek (7.3 percent) and the Ten Sleep (6.5 percent). Similar trends in survival were found in gill netting and electrofishing samples. Migration out of the reservoir was negligible for each strain. There were no strain differences in catchability by different methods (shore, boat) or gear (bait, artificial lure). Differences in growth between the fastest growing strains (Ten Sleep, Sand Creek) and the slowest growing strains (New Zealand, Fish Lake-Desmet) averaged as great as 16 mm in length and 43 g in weight. Differences in growth and survival among strains were great enough to span the range of angler satisfaction with numbers caught and size of fish caught from satisfactory to unsatisfactory. Therefore, strain selection can be a useful tool to improve fingerling stocking programs and manipulate the number of anglers who are satisfied with the angling experience.

Magister Educationis - MEd / The current study framed as, ‘Emerging Technologies for Teaching and Learning: An Investigation into the Role and Use Of iPads In English Second Language in Three Primary Schools in Northern Zambia,’ is situated in Northern Zambia in the Mungwi District. The study set out to investigate the role and use of emerging technology/-ies that is iPads, for literacy development in Grade six English Second Language schools. The purpose was to gain insight into the role emerging technologies play in fostering English Second Language (ESL) and literacy development in the era of new multimodal texts. This entailed acquiring an understanding of how highly ZeduPad tablets might facilitate meaning-making in the process of developing literacy skills.

Sponges are the descendants of the oldest members of the metazoan phylogenetic lineage and their genome contains animal specific genes but lack true tissues, organ systems, and neurons. Thus, the sponge model system can be used to elucidate origin of developmental processes. The PSED (RDGN) network (Pax/Six/Eya/Dac) is important in development of eyes, muscles, and other structures in Bilaterians. Similarly, sponges contain a precursor Pax-Six gene network. The Ephydatia muelleri (Em) PaxB protein binds to a Pax2/5/8 consensus sequence site and two cis-regulatory elements upstream and one intron sequence of EmSix1/2 (Rivera et al., 2013). This study aimed to determine if transcription factor EmSix1/2 binds upstream of EmPaxB using gel shift mobility assays, identify other downstream targets of EmSix1/2 using DNA immunoprecipitation, and to identify the recognition sequence of Six in sponges through sequencing. In conclusion, purified EmSix binds to DNA specific fragments (1 and 3), which may contain enhancer sequences located in the PaxB promoter region.Possible consensus recognition sequence of Six in sponges were also identified. The host immune response has various mechanisms to protect the organism from infections and invasions of microorganisms and cell damaging chemicals. One such mechanism is the elimination of reactive oxygen species aided by superoxide dismutase (SOD). A study showed that anti-neutrophil chemotactic factor antibodies recognize Tritrichomonas foetus SOD (Granger et al., 1997). During first casualties, SOD is released and triggers a host immune response. The parasites could use SOD to counter oxidative attacks by the leukocytes and damaged cells to protect surrounding parasites. We used the parasite Trichomonas vaginalis that causes trichomoniasis to determine if SOD acts a neutrophil (or other leukocyte) chemotactic factor in this parasite and characterize the expression and secretions of epithelial cells when treated with SOD6. HeLa cells treated with SOD6 showed an increase in the expression of IL-8 chemokine relative to TrxR treated cells. Scratch test assays showed that SOD may act as a macrophage chemoattractant as compared to TrxR but further tests are needed to confirm this.

I collaborate with Elders of the Six Nations of the Grand River Territory – mainly former vice-principals and principals – to share their stories about elementary school administration of the community’s day schools of the 1960s, 70s, and 80s, and of the larger consolidated schools thereafter. By engaging in storywork with them, their stories reveal that as Indigenous organizations like the National Indian Brotherhood/Assembly of First Nations (NIB/AFN) warned First Nations about mistaking administrative control, or delegated authority as it framed it, as real, local control over their children’s education, vice-principals and principals in Six Nations reframed it as inherent acts of self-determination and sovereignty over education. Drawing on Audra Simpson’s nested sovereignty, and Glen Sean Coulthard’s self-recognition to produce a more accurate representation of administrative control in the community, the author argues that vice-principals and principals in Six Nations did not mistake their practice as delegated authority but instead – as inherently sovereign actors – went through a process of negotiating self-determination and sovereignty within the Department of Indian Affairs and Northern Development Canada’s (DIAND) educational framework to upset its status quo of First Nations only managing educational programs and services. If sovereignty is understood to be a process, rather than a destination as Robert Allen Warrior suggests, then vice-principals and principals exercising administrative control on a daily basis in their schools should be recognized as inherently self-determining and sovereign. By sharing their stories, they reveal that they possess the authority to determine the definition and character of administrative control at the local level. The argument’s implication being that there are alternative ways of knowing and understanding administrative control in First Nations schools, rather than the national discourse that evolved in the decades following the NIB’s Indian Control of Indian Education. / Thesis / Master of Arts (MA) / I collaborate with Elders of the Six Nations of the Grand River Territory – mainly former vice-principals and principals – to share their stories about elementary school administration of the community’s day schools of the 1960s, 70s, and 80s, and of the larger consolidated schools of the 1990s and early 2000s.

Although water covers 70% of the earth's surface, less than 1% of it is freshwater that can be used for drinking. Even in Canada, where there is an abundance of freshwater in groundwater and in rivers and lakes, there are many indigenous communities that lack a sustainable source of drinking water. Such is the case for the Six Nations of the Grand River, the largest indigenous Reserve in Canada, located within an hour drive from major urban centers in southern Ontario and where less than 9% of the residents have access to safe, treated potable water. The major tributaries that drain the Six Nations reserve are part of the McKenzie Creek Watershed, which has been characterized as having the highest loading of sediments and nutrients to the lower Grand River, which eventually drains into the eastern basin of Lake Erie. This research project was initiated by the Six Nations community, who wanted an update on the prevalence of fecal contamination in their drinking water sources (wells, cisterns). Secondly, the community wanted to know the ecosystem health status of tributaries flowing through the Six Nations Reserve (McKenzie and Boston Creeks), and to determine if land uses in the watershed were negatively affecting the health of these streams. A study conducted in the summer of 2018 confirmed that 29% of the tap water tested in 75 households were contaminated with E. coli; 40% of the wells and 15% of the cisterns were contaminated and these were distributed throughout the Reserve with no apparent pattern. A study conducted in the summer of 2019 found that the McKenzie Creek was highly polluted with total phosphorus (P), total suspended solids, turbidity and total-ammonia nitrogen (N), while Boston Creek was highly polluted with soluble reactive P and E. coli as well as total-nitrate N. Nitrogen concentrations at 14 stations were highly and significantly related to percentage of agricultural land in catchments. Elevated levels of pollutants have been observed in the two creeks for three decades, indicating that conditions will not improve without remedial actions. / Thesis / Master of Science (MSc)
