Introduction: Osteoporosis is a major disease state associated with significant morbidity, mortality, and health care costs. Less than half of the individuals sustaining a low energy hip fracture are diagnosed and treated for the underlying osteoporosis. Objective: A multidisciplinary Canadian hip fracture working group has developed practical recommendations to meet Canadian quality indicators in post hip fracture care. Methods: A comprehensive narrative review was conducted to identify and synthesize key articles on post hip fracture orthogeriatric care for each of the individual sections and develop recommendations. These recommendations are based on the best evidence available today. Conclusion: Recommendations are anticipated to reduce recurrent fractures, improve mobility and healthcare outcomes post hip fracture, and reduce healthcare costs. Key messages to enhance postoperative care are also provided. [ABSTRACT FROM AUTHOR]

The recent introduction of new vaccines into the school-based immunization program in British Columbia (BC) included monitoring of adverse events following immunization (AEFI) for these new vaccines. This commentary discusses different methods used to collect AEFIs in school immunization campaigns and the effects on response rate. The results of a study using an internet-based tool inspired this paper. The study examined adverse events following human papillomavirus (HPV) vaccine given to grades 6 and 9 students. The low response rate of the internet survey resulted in insufficient findings regarding adverse events. Consequent to the analysis of the study's data, a literature review was conducted to examine survey methodologies used to collect adverse event data following school-based immunization of adolescents. A PubMed search used various combinations of the following terms: vaccine, immunization, immunization programs, reactogenicity, adverse reactions, safety, adolescent, schoolchildren, and survey. Potentially relevant papers were identified based upon the titles and abstracts and subsequently reviewed. Only four studies were deemed appropriate for comparison purposes: all were done in Canada.

Goal and Background. The LCA methodology is used to compare the potential environmental benefits of an emerging bio- technology, enzyme-bleaching, with those of elemental chlorine free (ECF) bleaching, an existing technology that is widely used in paper making. Through the use of biodegradable enzymes to supplement, or eventually to replace, chemicals in the bleaching process to extract lignin, enzyme bleaching processes are aimed to reduce the use of chlorine based bleaching chemicals and to achieve cost savings by circumventing investment into oxygen delignification or ozone bleaching technology. Scope and Method. The assessment is conducted using SimaPro 4.0 and focuses on the processes within the bleach plant stage. For this study, ECF is replaced by enzyme bleaching only in the first stage of the bleaching process. Because this is a comparative study, all upstream and downstream processes are excluded. The impact categories based on Eco-indicator 95 are used to characterize the inventory data in this study. Other methodologies, such as Eco-indicator 99 and CML 2000, have not been chosen as they are more region-specific and are not yet fully applicable to the Canadian environmental condition. A new initiative to develop a Canadian Life Cycle Impact Assessment (LCJA) Method is ongoing at the Interuniversity Reference Center for the Life Cycle Assessment, Interpretation and Management of Products, Processes and Services (CIRAIG), Ecole Polytechnique, Canada. Results and Conclusion. The analysis shows that the introduction of enzyme bleaching into the ECF process significantly im- proves the overall environmental performance in the majority of the impact categories. Extending the substitution of enzyme bleaching for chlorine dioxide is warranted. Of the three im- pact categories where increased impact was noted, two of these which increased emissions of greenhouse gases and increased incidence of summer smog, would be completely eliminated if the enzyme mediator was manufactured at the point of use. There remains a potential for increased impact from eutrophication, which would need to be managed. Recommendations and Outlook. With the only partial substitution of ECF by enzyme bleaching examined here, chlorine dioxide consumption, energy consumption, NaOH consumption, and transportation remain the key hot spots and warrant further research. Anything that can be done to replace or reduce chlorine dioxide consumption will benefit the environment. [ABSTRACT FROM AUTHOR]

The article focuses on the factors influencing the 7-ethoxyresorufin-o-deethylase (EROD) activity in Feral Winter Flounder which was exposed to effluent from a pulp and paper mill in Newfoundland, Canada. Aquatic organisms can biotransform organic chemicals by producing a series of enzymes which include the mixed function oxygenase (MFO) system. Effluent discharged by pulp and paper mills have been reported to induce MFO activity in a number of fish species. Winter flounder were captured at depths of 5 to 10 m by SCUBA divers. Results showed that EROD activity varied depending on water temperature, gender, sexual maturity and site of sampling in feral winter flounder inhabiting the fjord receiving effluent from the pulp and paper mill.

The lack of yield response to the N-fertilizer strategies highlights the importanceproper timing of N-fertilizer application for potatoes which will allow reduction of N-fertilizer rate without compromising tuber yield. Two potato cultivars (Vigor and Lady Claire) were used in this study and potato tubers were collected from a potato farm in Alberta, Canada. A thorough understanding of such changes is required to optimize quality and yield potential.. A study consisting of five contrasting potato cultivars was undertaken to investigate the physiological and biochemical response of potato cultivars to N rate in terms of tuber dry matter accumulation, partitioning and quality. One method for reducing N loss to the environment is growing potatoes that require less added N. Identifying Nitrogen Use Efficient (NUE) potato varieties and characterizing their response to N stress are necessary steps to breeding for NUE in potato. Three potato-based cropping sequences, wheat-potato-wheat, canola-potato-wheat, and fababean-potato-wheat were evaluated under irrigation at the Canada-Manitoba Crop Diversification Centre at Carberry, Manitoba, Canada.

The present study first describes the variations in concentrations of 12 chemical elements in groundwater relative to salinity levels in Southern Quebec (Canada) groundwater systems, and then uses this data to develop an empirical predictive model for evaluating groundwater chemical composition relative to salinity levels. Data is drawn from a large groundwater chemistry database containing 2608 samples. Eight salinity classes were established from lowest to highest chloride (Cl) concentrations. Graphical analyses were applied to describe variations in major, minor, and trace element concentrations relative to salinity levels. Results show that the major elements were found to be dominant in the lower salinity classes, whereas Cl becomes dominant at the highest salinity classes. For each of the major elements, a transitional state was identified between domination of the major elements and domination of Cl. This transition occurred at a different level of salinity for each of the major elements. Except for Si, the minor elements Ba, B, and Sr generally increase relative to the increase of Cl. The highest Mn concentrations were found to be associated with only the highest levels of Cl, whereas F was observed to be more abundant than Mn. Based on this analysis of the data, a correlation table was established between salinity level and concentrations of the chemical constituents. We thus propose a predictive empirical model, identifying a profile of the chemical composition of groundwater relative to salinity levels, to help homeowners and groundwater managers evaluate groundwater quality before resorting to laborious and costly laboratory analyses.

This paper contributes to international feminist debates on shared parenting and family violence via reforms to Canada's Divorce Act, in force since 2021. Looking backwards, it reviews parliamentary debates and early judicial discussions. The documentary review reads the reforms as an unstable compromise between calls from feminist voices and experts on family violence and from groups representing fathers. Family violence is now defined broadly and declared relevant to children's welfare. But language in the statute may undermine its seriousness. Exposing the tensions underlying these reforms is useful for Canadian participants in family justice and for scholars, practitioners, and policymakers elsewhere, exemplifying the promise and perils of reform in this area. Looking ahead, the paper offers recommendations to higher courts. Appellate judges should read rules on contact with both parents and parental cooperation in the light of the new recognition of family violence, taking the latter as an overarching objective of the statute.

In contrast to the summary paper, this introductory paper is focused on providing a more detailed description of the conference papers which were submitted for publication. [ABSTRACT FROM AUTHOR]

The environmental benefits of water table management (WTM), as a method to reduce nitrate pollution, are well known. However, there are few published studies on the effects of WTM on water use efficiency (WUE). This paper highlights the agronomic interest of WTM for increasing WUE of irrigated grain corn production. A field study was conducted in 2001 and 2002 at a large scale WTM research facility in Québec, Canada. The region experienced periods of drought during the two growing seasons. This study shows that, by keeping the water table at 0.80 m below the soil surface, there were on average 35% increases in grain corn yields, compared to conventional free drainage. The WUEs obtained with WTM (5.1 kg m−3 in 2001 and 7.1 kg m−3 in 2002) indicate that the method is generally more water efficient than conventional sprinkler and furrow irrigation. The WUE of WTM also compares well with that of water conservation methods such as alternate furrow irrigation and deficit sprinkler irrigation. Moreover, WTM requires low inputs in terms of equipment, energy, and labour, because it makes use of existing subsurface drainage systems, which are widespread in Eastern Canada due to the region's soils and climate, and because of its design, which does not necessitate high-pressure pumps and allows for automated management. Hence, WTM appears to be an interesting alternative to conventional irrigation methods due to its combined environmental and agronomical benefits. [ABSTRACT FROM AUTHOR]

The article discusses polarization and middle class. It references the 1992 article "Polarization and the Decline of the Middle Class: Canada and the U.S.," by James Foster and Michael Wolfson in the same issue. The authors used Lorenz curve to determine pay inequality and Gini-like index to measure bipolarization. It is said that the authors' concept of polarization was divided between people with incomes below and above the median income.

In Canada, Environmental Effects Monitoring (EEM) programs exist within two regulations: the Pulp and Paper Effluent Regulations and the new Metal Mining Effluent Regulations under the Canadian Fisheries Act. EEM provides a biological, effects-based feedback loop to assess the effectiveness of technology-based regulations in protecting receiving environments. The promulgation of the Pulp and Paper Effluent Regulations, in 1992, represented a significant step forward in the Canadian regulatory approach by incorporating directly into a regulation a requirement to assess the effects of effluent discharges on receiving environments using proven scientific monitoring methodologies. Similarly, an assessment of the aquatic impacts of mines resulted in recommendations to amend the Metal Mining Effluent Regulations, recently promulgated in 2002, and includes an EEM program as a science-based feedback loop. As such, these regulations recognize the possibility that national, technology-based standards may not necessarily protect all receiving environments because of the diversity and variability of both discharges and receiving sites across the country. Since that time, EEM has improved its flexibility by considering both advances in science and the uniqueness of monitoring sites across Canada to allow the most appropriate and cost-effective monitoring approaches at each site while maintaining national consistency. This paper discusses the use of monitoring under two Canadian regulations to assess effects on aquatic ecosystems. As well, the National EEM approach to maintaining up-to-date scientific practices in a national regulatory program is discussed using examples. [ABSTRACT FROM AUTHOR]

The social distancing imposed by the Covid-19 pandemic accelerated the digitalisation of societies, which also influenced habits related to the consumption and dissemination of news. In this context, older individuals are often blamed for contributing to disinformation, which is associated with the echo chambers fostered by social media. Mass media, social media and personal communication tools act as mass, social or personal intermediaries when it comes to keeping up to date with the news. This paper analyses the preferred intermediaries of older online adults (aged 60 and over) for following the news and how they change over time. We analysed two waves of an online survey-based longitudinal study conducted in Canada and Spain, before Covid-19 pandemic (2016/17), and during Covid-19 (in 2020). We found that most participants exclusively use mass intermediaries or combine mass with social and personal intermediaries to keep abreast of the news. However, only 28% of respondents inform themselves exclusively through the alleged echo chambers of social and personal intermediaries. Results also show that media ecologies evolve in different directions, and, despite the forced digitalisation driven by the pandemic, digital media usage did not always increase or evolve towards newer technologies. This paper contributes to understanding the diverse intermediaries used by older adults to obtain news and how such media ecologies can contribute to contrasting different sources of information beyond the alleged echo chambers of social media.

Objectives: Statistics Canada administers the Agricultural Census every 5 years, and this paper presents unsuppressed data from the 2016 and 2021 Census. The data set encompasses detailed information on farm types, sizes, technology choices, and a demographic profile of farm operators from the 2021 Census. Data on farm characteristics and operator demographics is crucial for understanding innovation in agriculture and formulating evidence-based policies. Data description: The data sets cover the two most recent agriculture censuses of 2016 and 2021, presenting data on the number of farmers by region, farm type, size, and the adoption of technologies. Additionally, a third data set lists the number of farm operators by age and sex. The census questionnaire inquires about using different technologies, varying the types across the two census periods. Notably, there is no data suppression in these data sets, and they cover all 10 provinces in Canada, excluding the three territories. Farm types are categorized based on the North American Industry Classification System (NAICS), and farm size is measured in acres. [ABSTRACT FROM AUTHOR]

Using the example of an industrial site in Edmonton, Alberta, this paper argues that industrial ruins represent instantiations of abstract abandonment, a kind of real abstraction that directly articulates to the logic of capital. Drawing from excavations of the industrial ruins of Mill Creek Ravine, one of the first industrial areas in Edmonton, this paper reveals how sites of abstract abandonment congeal critical histories of both abandonment and its afterlives. The history of these ruins, and the communities that emerged after they were abandoned materialize the failures of capitalist fantasies, as well as the sprouts that grow in its cracks.

This paper represents one of the first critical social science interrogations of an agrifood just-in-case transition. The just-in-case transition speaks to a philosophy that values building buffers and flexibility into longer value chains to make them more resilient to shocks, which stands in contrast to the just-in-time philosophy with its emphasis on long, specialized, and often inflexible networks. Influenced by COVID-related disruptions and climate change induced uncertainties, the just-in-case transition examined here centers on the heightened interest in vertical farm-anchored supply chains. Interviewing actors responsible for promoting vertical farm-anchored local supply chains in the US and Canada, I attempt to sketch out how these spaces, infrastructures, and practices care. Put differently, as understood through a feminist ethics of care, whom and what are cared for and how is care practiced in these just-in-case transitions and why? Enumerative politics was observed in the data—the idea that we can make care count. Practices and discourses linked to infrastructural/supply chain transitions are highlighted that result in care being narrowly conceived as a technical or transactional matter. The paper concludes reflecting on what it means to afford just-in-case agrifood transitions animated by matters of care that hold greater emancipatory potentials. [ABSTRACT FROM AUTHOR]

This paper reviews major structural drivers of place-based health disparities in the context of Canada, an industrialized nation with a strong public health system. Likelihood that the COVID-19 pandemic will facilitate rejuvenation of Canada's northern and remote areas through remote working, advances in online teaching and learning, and the increased use of telemedicine are also examined. The paper concludes by identifying some common themes to address healthcare disparities for northern and remote Canadian residents. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this paper is to add to the research literature and begin to fill the gap in knowledge about shared parenting arrangements for women with young children and who have experienced domestic violence (DV), in three Canadian provinces; Alberta, Manitoba and Ontario. Method: This paper reports on the qualitative findings from a mixed methods study on shared parenting from women with children ages 4 and under. Twenty women participated in one-on-one individual interviews through electronic platform utilizing Zoom. Thematic analysis is used to analyze the data. Results: Despite efforts to not exclusively recruit women who had experienced domestic violence (DV) from their former partner, all participants identified as survivors of DV and ongoing survivors of DV, specifically, coercive controlling behaviours. Five themes describe the women's experiences of shared parenting with young children: 1) walking a tight-rope; 2) navigating post-separation relationships; 3) emotional realities of shared parenting; 4) shared parenting outcomes; and, 5) structural challenges. Conclusions: This paper not only adds to the significant and longstanding gap in knowledge directly from women with children ages 4 and under in shared parenting relationships, and who have experienced DV, and also helps to inform social service and legal actors. It is timely with the amendments to the Divorce Act in Canada which now includes DV as a factor in determining the best interests of the child. [ABSTRACT FROM AUTHOR]

The Canadian Environmental Assessment Act (CEAA) defines the federal environmental assessment (EA) process for evaluating the likelihood that development projects (e.g., roads, buildings, factories) will have impacts on the environment. Environmental effects monitoring (EEM) programs for mining and pulp and paper mills under the Federal Fisheries Act, define the process that is to be used to evaluate existing effects caused by liquid effluents discharged by operating facilities. The EA process occurs before a project is approved, and involves predicting whether the project is going to cause significant environmental impacts. The EEM process occurs after a project is operational, and involves determining whether an existing project has had or is continuing to have significant impacts on the environment. Ideally, the processes are complimentary, with the EA process identifying environmental attributes considered important, and the EEM process demonstrating whether predicted or unpredicted impacts occurred. The two processes are usually done in isolation so potential synergies are lost. The point of this manuscript is to justify bridging the two processes. We use the aquatic environment as the example, and briefly describe the EEM process, aquatic environment indicators, experimental designs, and typical environmental thresholds, to illustrate how the EEM and EA processes link.
