Edward 'Ned' Hanlan: imagining Canadian masculinity and national identity from the success of an early rowing champion
No full textThis study explores Canadian professional rower Edward ‘Ned’ Hanlan who became nationally and internationally famous in the mid-to-late Victorian Era (1870s-90s). Applying a deconstructionist methodology to analyse illustrations and text of Hanlan’s numerous races, this project explores how nationalism and manliness were depicted and understood during this time. Images published in two Canadian magazines, Grip and the Canadian Illustrated News are examined to reveal how and why Hanlan was frequently exemplified as a role model for Canadians. The print media’s representation of Hanlan was informed by broader influences such as the Canada First movement and the appropriated sport of lacrosse to provide readers context to appreciate Hanlan as the standard for what it meant to be Canadian. Grip and the Canadian Illustrated News focused on connections between athletic prowess and manliness, and Hanlan’s physical composition in these images is examined through a consideration of hegemonic masculinity, the self-made man, reclaiming masculinity, muscular Christianity, and fatherhood. By equating Hanlan’s feats with the emergence of Canadian nationhood, the rowing world championships resonated with Canadians as well as serving the print media’s interests in promoting a Canadian masculine ideal
Family-centred care for parents providing care for involuntary adults with a mental health diagnosis: implications for service providers
No full textCaregivers who provide care for an involuntary adult with a mental health diagnosis often experience significant emotional and psychological distress. Limited recognition from healthcare providers frequently leads to the marginalization of parents and families, raising concerns about their overlooked experiences in the healthcare system. Despite growing awareness of the importance of family involvement in involuntary adult mental health, there has been little effort in healthcare systems to integrate the support of families due to complex systemic barriers, with confidentiality being a primary concern. There is limited research for Canadian service providers on how to make their practice more inclusive for clients and families without breaching confidentiality. To address this gap, a comprehensive review of the research and literature on this topic was conducted, resulting in ethically informed recommendations for service providers. The final contribution of this project includes a draft manuscript discussing these recommendations to inform service providers of parents' perspectives and to offer insight into how families can be supported in the treatment of involuntary adults without breaching confidentiality
A time series analysis of trending dengue cases in Sri Lanka.
No full textThe study aimed to predict dengue case numbers in Sri Lanka from January 2024 to December 2025. The prediction will assist the National Dengue Control Unit of Sri Lanka in assessing the potential dengue case numbers before a seasonal dengue crisis. This allows the Ministry of Health of Sri Lanka to plan effective healthcare mobilization and manage its resources during dengue seasons. Secondary data on all island dengue cases was obtained from the National Dengue Control Unit's national surveillance system from 2015 to 2023. A seasonal ARIMA(0,1,1)(0,0,2)[12] model was generated in R software by the forecast package’s time series function based on the Box-Jenkins method. The ARIMA model was validated as a good fit for prediction with the Ljung-Box (p-value >0.05), Shapiro-Wilk (p-value >0.05), and ADF (p-value <0.05) tests. The prediction’s MAPE was estimated as accurate for forecasting (4.46). The seasonal ARIMA model demonstrated the ability to make a short-term prediction in univariate analyses
Donor-stabilised fluorido cations of groups 15 and 16
No full textThe fluoride-ion donor properties of the strong Lewis-acids SbF5 and AsF5 were investigated. In the presence of the bidentate nitrogen base 1,10-phenanthroline (phen) SbF5 and AsF5 were found to autoionise generating [PnF4(phen)][PnF6] (Pn = As or Sb) salts; this is the first time that SbF5 has demonstrated the ability to act as a fluoride-ion donor. In the presence of the more flexible nitrogen base 2,2′-bipyridine (bipy), SbF5 was again found to autoionise yielding [SbF4(bipy)][SbF6], whereas AsF5 forms the neutral adduct (AsF5)2·bipy. In the presence of the tridentate base 2,2′:6′,2′′-terpyridine (terpy) SbF5 autoionises to form [SbF4(terpy)][SbF6]; the [SbF4(terpy)]+ cation is the first structurally characterised fluorido Sb(V) complex with a coordination number of seven and adopts a heavily distorted pentagonal bipyramidal geometry. The structure and bonding in these unique systems was studied using a combination of spectroscopic, crystallographic and computational techniques.
The [SF3]+ cation forms 1:1 adducts with pyridine and 4-dimethylaminopyridine (DMAP) which adopt different structures. Whereas pyridine coordinates in the axial position of the seesaw-geometry, DMAP is located in the equatorial position. The latter structure leads to facile dismutation to the [SF2(dmap)2]2+ cation and SF4, while [SF3(py)]+ is stable towards dismutation. Further dismutation afforded the square-pyramidal [SF(dmap)4]3+ cation. Attempts to form adducts of [SF3]+ cation with triphenylphosphine oxide, resulted in deoxofluorination
Prevalence of work-related musculoskeletal disorders among dental workers in Enugu metropolis, Nigeria
No full textOpen access article. Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International license (CC BY-NC-SA 4.0) appliesBackground:
Work-related musculoskeletal disorders (WRMSD) are the main occupational health hazard among several clinicians, but its prevalence among dental workers in Nigeria has not been well-studied.
Objective:
This study evaluated the pattern and prevalence of WRMSDs among dental workers in the Enugu metropolis, Nigeria.
Materials and Methods:
Six hospitals with dental clinics participated in this cross-sectional survey in the Enugu metropolis. One-hundred and fifty (150) standardized musculoskeletal symptom (Nordic) questionnaires were adopted and distributed, of which 141 were returned. The questionnaire elicited data on demographic characteristics and carrier profiles, ergonomics, and the body parts involved in the occupational activities.
Results:
The results indicated that 83% of the respondents sustained musculoskeletal injury more than once. Bending (66%) and performing repetitive tasks (58.2%) were the most performed risk activities. The lower back (66%) was the most affected body part, followed by the upper back (58.9%), neck (51%), shoulder (47.5%), and hip (46.1%). The most common preventive measures taken by individuals were resting (57%) and avoiding lifting (53.2%).
Conclusion:
There is a high prevalence of WRMSD among dental workers, with potential to having negative effect on their work habits, and reduced productivity.Ye
Warmer air temperatures predicted to result in wetland drying in the Upper Columbia River Valley, British Columbia, Canada
No full textOpen access article. Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International license (CC BY-NC-ND 4.0) appliesClimatic warming is likely to affect the Canadian Rockies, leading to changes in the land cover (LC) and hydrological cycles. This study estimates climate-induced changes in LC (open water, marsh, wet meadow, and woody/shrub) in the Upper Columbia River Wetlands (UCRW), British Columbia, Canada, from 1984 to 2040. An artificial Neural Network (ANN) approach was used with Landsat series archive data from 1984 to 2022 to project seasonal LC change from 2020s to 2040s. Concurrently, hydroclimatic-based models (using air temperature and precipitation to predict river discharge at the UCRW, 1984–2022) were developed (average Nash Sutcliffe: training 0.75 and validation of 0.70) to predict (1984–2040) river discharge forced by Representative Concentration Pathway (RCP) 4.5 and 8.5. The 1984–2022 regression between river discharge and UCRW open water area was forced by RCP scenario river discharge results, calculating open water area for both scenarios. ANN-predicted LC with a Kappa of 0.85 (average of all seasons) for 2020s reference and projected LC, and 0.82 for reference and projected LC change maps (2000s–2020s). From 2020s to 2040s, the ANN projected a reduction (−5 %) of open water areas during late summer (August to mid-September) in the UCRW, consistent with RCP 4.5 forecasts. The peak of the open water area in the UCRW is projected to shift from summer (late-May to July) to spring (April to mid-May) in both RCP scenarios. The projected changing hydrological conditions reduced the marsh area (−1 % to −12 %) and increased the wet meadow (+1 % to +4 %) mostly in the summer and late summer. Meanwhile, woody and shrubby vegetation on the floodplain increased (3 % to 5 %), indicating that the floodplain is projected to dry out.Ye
Atonaan Blackfoot quillwork
No full textMy art practice focuses on Siksikaitsitapi or Blackfoot porcupine quillwork techniques while incorporating my contemporary art practice. My art practice is informed by stories of how I continue to work from a lived experience as a Blackfoot artist raised within the Blackfoot ways of being, also referred to as Siksikaitsitapi. I have viewed the digital images from Apani Blackfoot Digital Library and Mootookakio’ssin website. I feel a responsibility to learn and preserve the art of quillwork and to take pride and celebrate in my ancestorial art form. Quillwork reflects the connection to my ancestors that I want to honor. My quillwork practice, both historic-based and contemporary, will evaluate connections between Siksikaitsitapi existence within cosmology belief systems and the continuance of affirming cultural rejuvenation while contributing to the respect deserving to the environment
Non-pharmacological intervention to reduce responsive behaviours in seniors with dementia at an assisted living facility in Calgary, Alberta
No full textResponsive behaviours such as agitation, aggression, and wandering among seniors with dementia remain a challenge for healthcare staff. While medications are commonly used, they carry risks, making non-pharmacological interventions (NPIs), such as music and physical exercise, safer, person-centred alternatives that enhance quality of life. Despite policy mandates and mandatory dementia education, a gap persists between theoretical knowledge and practical application in care settings. Standardizing education across academic and workplace programs, with emphasis on tailoring interventions to individual preferences and life history, is essential. To address this gap, a 30-minute education session was delivered to staff at Cogir Senior Living McKenzie Towne. The session connected theory to practice, and staff reported a deeper understanding of responsive behaviours and the role of NPIs in dementia care. Findings highlight the importance of ongoing, evidence-based, and standardized training to improve care quality and support the well-being of individuals living with dementia
Detecting graphical and digraphical regular representations in groups of squarefree order
No full textOpen access article. Creative Commons Attribution 4.0 International license (CC BY 4.0) appliesA necessary condition for a Cayley digraph Cay(R,S) to be a regular representation is that there are no non-trivial group automorphisms of R that fix S setwise. A group is DRR-detecting or GRR-detecting if this condition is also sufficient for all Cayley digraphs or graphs on the group, respectively. In this paper, we determine precisely which groups of squarefree order are DRR detecting, and which are GRR-detecting.Ye
New growth and the fossilized economy: sustainable development, discourse, and the case of recommodification
No full textxiv, 141 pages : illustratedStarting in the 1960s, there was increased public awareness of environmentalism and, later, anthropogenic climate change. Public and private interests began to focus on the ‘issue’ of the environment, and in 1987, the UN Our Common Future Report (later known as the Brundtland Report) introduced the concept of sustainable development (SD). Using this concept as my guide, my research question is: Is the model of SD, as presented in the 1987 Brundtland Report, effective? I argue that SD, with an inherent emphasis on development and (economic) growth, is not a useful tool to advance effective climate action. Through participant observation at a Canadian corporate/climate conference and interviews with young sustainability professionals with experience in the public and private sectors (n=8), I argue that the concepts of sustainability and SD have been co-opted (through discourse and action) by corporations looking to profit. As such, I observe a corporate culture which embraces and adheres to the model of SD, but which uses SD to justify business- and growth-first approaches to environmentalism. I then outline a model of ‘recommodified SD,’ informed by the need to ‘sell’ the idea of SD (in its corporate and commodified form) to and from staff and their organizations. Ultimately, I present an argument on the discursive functionality of SD in perpetuating the idea that There Is No Alternative (TINA) from status-quo approaches to climate action
