Canada's Pulse 2011
Ipsos Canada — 2017-02-02 The Ipsos Canada’s Pulse series offer a sampling of public opinion at the municipal level in Canada’s largest urban centres. These surveys, commissioned on behalf of Global Television, query respondents on national as well as local issues and concerns. Respondents from each city within the survey are asked to answer questions particular to their municipality and province. The survey therefore reveals local and timely data on topics such as municipal and community leadership, commuting and traffic, elections, taxation, the economy, and culture. The 2010 Canada's Pulse poll is accompanied by a series city-specific reports for further analysis. This survey has a sample of 6883 Respondents. "Changes in methodology between 2009 and 2010 means that researchers should use caution when drawing comparisons at the national level: The 2009 "National" figures were an aggregate of all of the cities/regions combined and was therefore best described as a sample of urban Canadians. The 2010 [and 2011] "National" figures are a truer reflection of a national sample (including rural Canadians). Thus, tracking comparisons on a national level should be used with caution. For example, while concern for crime appears to be down on a national level [in 2010], it is likely that crime is less of a concern for rural Canadians and this brings down the proportion of mentions of crime. Tracking at a city level is unaffected. " (Adapted from Ipsos Canada, Canada's Pulse 2010 Reports)

2021 Redux Survey of Visible Minority Librarians of Canada
Li, Yanli; Kumaran, Maha; Cho, Allan; Ly, Valentina; Fernando, Suzanne; Miller, Michael David — 2021-08-26 In 2021, the Visible Minority Librarians of Canada (ViMLoC) Network conducted its second comprehensive survey on visible minority librarians working in Canadian institutions. As a followup to the first 2013 survey, ViMLoC examined changes in the library landscape with regards to visible minority librarians in various librarian positions. Data were collected from January to March 2021 on visible minority librarians’ demographics, education, and employment situations. The survey was administered and distributed using Qualtrics in English and French. <p><p> The user guide and results summary in this dataset presents aggregated data for 162 visible minority librarians from the English survey (138) and the French survey (24). Survey results will help ViMLoC identify the needs of visible minority librarians and propose projects to empower them in their current positions or their future career development. The data can be also useful to library administrators, librarians, and researchers working on multicultural issues, diversity, recruitment and retention, leadership, library management, and other related areas. http://creativecommons.org/licenses/by-nc-sa/4.0'}

Data for: Early and late cyanobacterial bloomers in a shallow, eutrophic lake
Venkiteswaran, Jason; Baulch, Helen M.; Painter, Kristin; Simon, Dana F.; Duy, Sung Vo; Sauvé, Sébastien — 2022-05 This dataset contains data and code for <a href="https://doi.org/10.1002/essoar.10510183.2">"Early and Late Cyanobacterial Bloomers in a Shallow, Eutrophic Lake"</a>, published in <i>Earth and Space Science Open Archive</i>, 2022. Cyanobacterial blooms present challenges for water treatment, especially in regions like the Canadian prairies where poor water quality intensifies water treatment issues. Buoyant cyanobacteria that resist sedimentation present a challenge as water treatment operators attempt to balance pre-treatment and toxic disinfection by-products. Here, we used microscopy to identify and describe the evolution of cyanobacterial species in Buffalo Pound Lake, a key drinking water supply. We used indicator species analysis to identify temporal grouping structures throughout two sampling seasons from May to October 2018 and 2019. Our findings highlight two key cyanobacterial bloom phases – a mid-summer diazotrophic bloom of Dolichospermum spp. and an autumn Planktothrix agardhii bloom. Dolichospermum crassa and Woronchinia compacta served as indicators of the mid-summer and autumn bloom phases, respectively. Different cyanobacterial metabolites were associated with the distinct bloom phases in both years: toxic microcystins were associated with the mid-summer Dolichospermum bloom and some newly monitored cyanopeptides (anabaenopeptin A and B) with the autumn Planktothrix bloom. Despite forming a significant proportion of the autumn phytoplankton biomass (> 60%), the Planktothrix bloom had previously not been detected by sensor or laboratory-derived chlorophyll-a. Our results demonstrate the power of targeted taxonomic identification of key species as a tool for managers of bloom-prone systems. Moreover, we describe an autumn Planktothrix agardhii bloom that has the potential to disrupt water treatment due to its evasion of detection. Our findings highlight the importance of identifying this autumn bloom given the expectation that warmer temperatures and a longer ice-free season will become the norm. Dataset mirrors <a href="https://github.com/biogeochem/buffalopound_blooms/tree/176ff61768f1e5e5d485b53b72c68c8f287ca83f">2022-07-12 commit</a> of Buffalopound_blooms repository in Github.

Relationships between online activism, perceived sexism, gender identity and well-being in Canadian undergraduates, 2013-2017
Foster, Mindi D. — 2018 Three studies, each with different operational definitions of online activism, showed a similar pattern: online activism enhanced the relationship between gender identity and well-being. Study 1 analyzed the word content of women tweeting about sexism; the use of female words correlated with the use of well-being words. Studies 2 and 3 were a questionnaire and experimental study, respectively. In both studies, perceiving sexism as pervasive predicted greater gender identity, which predicted greater well-being. These relationships held for those believing online activism is active vs. passive (Study 2) and for those induced to participate in online activism vs a control group (Study 3).

Isotope data and associated attributes for 25 thermokarst lakes along the Inuvik – Tuktoyaktuk Highway, 2018
Wilcox, Evan J.; Marsh, Philip; Wolfe, Brent — 2022-04-25 This dataset contains water isotope concentrations measured from 25 lakes at five time points in 2018, along with snowpack and rainfall isotope concentrations from 2018. The lakes spanned a ~70km stretch of the Inuvik to Tuktoyaktuk Highway (ITH). Rainfall samples were collected in Inuvik, while snowpack samples were collected within the vicinity of the Trail Valley Creek Research Station. The dataset also contains lake and watershed characteristics for the 25 lakes that were sampled for water isotope analysis. Lake-specific properties include surface area, watershed position, depth, latitude, longitude, and elevation, while watershed-specific properties include surface area, average hillslope angle, drainage density, and ice-wedge polygon coverage. Watersheds were delineated using a 2-metre resolution digital elevation model and the D8 algorithm. Within each watershed, the areas of ice-wedge polygons were identified visually from satellite imagery and digitized manually. Drainage density was calculated as the length of all flowpaths with a contributing area greater than 5000 m2, and then divided by the total area of the watershed.
