Background: Good nutrition and access to healthy foods are essential for child growth and development. However, there are concerns that Canadian children do not have a healthy diet, which may be related to dietary choices as well as lack of access to healthy foods. The FANS (Food and Nutrition Security for Children and Youth) study examined the nutrition and food security status of youth in the province of Manitoba, Canada. This paper describes methods, dietary intakes, and body mass index for the FANS study. Methods: This cross-sectional study included 1587 Manitoba grade nine students who completed a self-administered web-based survey. Data was collected on demographic characteristics, dietary intake (24-h recall), food behaviors, food security, and self-report health indicators. Dietary data was compared to national dietary guidelines (Dietary Reference Intakes and Canada's Food Guide). Mean and median nutrient and food group intakes were calculated with corresponding measures of variability. Chi-square tests compared percentage of respondents not meeting key nutrients and food groups. Significant differences in percentage of total servings for each food group were determined by a Kruskal–Wallis test, and differences between different caloric groups were assessed using Dunn's test for post-hoc comparisons. Results: Half of study respondents were female (50.5%). Median energy intake was higher in males (2281 kcal) compared with females (1662 kcal), with macronutrient distribution of 52%, 16%, and 32% for carbohydrates, protein, and fats respectively. Most participants consumed inadequate fibre (94%), vitamin D (90%), and calcium (73%), while median sodium intakes exceeded recommendations for males but not females. A majority of participants did not meet Health Canada's recommendations for food group servings: Vegetables and Fruit (93%), Milk and Alternatives (74%), Meat and Alternatives (57%) and Grain Products (43%). Other Foods, including sugar sweetened beverages and juice, were consumed by most participants. Higher energy consumers had a greater proportion of food servings coming from Other Foods. 72.1% of students were classified as having a healthy weight and 25% were classified as overweight or obese. Conclusion: Poor dietary intakes and body mass index values indicate an urgent need for policy and program strategies to support healthy eating habits and food awareness in Manitoba youth.

Pilot projects in the past that have experimented with a Guaranteed Basic Income (GBI) in Manitoba and Ontario, and a recent study of the feasibility of a GBI in British Columbia, indicate that provinces are not in an ideal position to successfully implement an affordable and effective GBI. However, a GBI implemented by the federal government, financed by eliminating the GST credit and lowering personal tax exemptions, could be both effective and affordable. It could also do so without requiring the elimination of those provincial social assistance programs that are more deeply targeted toward people’s needs. By using its revenue powers, the federal government could create more fiscal capacity for the provinces to provide other cash and in-kind social supports, allowing for greater provincial benefit targeting. The federal government’s centrality in designing and implementing tax structures and collecting tax revenue make it singularly suitable for administering and delivering a GBI. Financing the GBI by eliminating the modest GST credit and lowering the current basic personal income tax exemption could provide a significant reduction in the rate, depth and intensity of poverty in Canada, without imposing an excessive tax burden on Canadians. If provinces use the GBI as a replacement for certain less-targeted provincial social assistance income transfers, the freed-up payments and reduced caseloads could also allow provinces to target more effectively those needs not addressed by the GBI. The recent COVID-19 pandemic exposed longstanding gaps in Canada’s incomesupport frameworks, with lower-income workers facing exceptional economic vulnerability. At the same time, the Canadian Emergency Response Benefit proved edifying in terms of how to best design a basic-income program. In addition, the federal government’s experiences with the poverty-reducing impacts of the Canada Child Benefit, the Old Age Supplement and the Guaranteed Income Supplement have moved Canada closer than ever to a workable GBI. While it comes with additional costs, those costs will be less burdensome than many GBI skeptics might believe. They must also be put into perspective, by comparing them against the costs of current and, in many cases ineffective income transfers and, just as importantly, against the human cost of leaving more Canadians living in poverty.

Pre-contact Indigenous Nations were vibrant with their own legal, government, and education systems. Indigenous education is community-led and grounded in the spiritual, emotional, physical and mental development of the child. Teachings are tied to the land following the natural cycles, and language is passed down through ceremony and time on the land. Following the creation of the Canadian state, Indigenous education systems were eroded, leaving detrimental impacts on communities and youth that are ongoing today. In recent decades, many communities have taken the initiative to restore community-led Indigenous education systems. The work presented here, ininiw kiskinomākēwin, was collectively built with both ininiwak and anishinabe Elders and educators from Northern Manitoba and can be adapted by other First Nations groups across Canada. Ininiw kiskinomākēwin conveys the pre-contact methods for ensuring children and youth grow and become healthy, contributing members of society, and includes teachings involving family, community, language, land, and spirit. The implementation of this work is ongoing; critical components related to building a local teacher workforce, engaging Elders, supporting parents and having access to the land will shape how we choose to educate current and future generations.

Background: To develop effective public health policies, programs, and services tailored to the unique sexual health needs of migrant populations, it is essential to understand the myriad socio-ecological factors that influence their sexual health. This qualitative community-based participatory study aimed to explore factors influencing migrants' sexual health at different socio-ecological levels in a Canadian setting. Methods: Participants (n = 34) from African, Caribbean, Black; Latin American; South Asian; Middle Eastern, as well as East and Southeast Asian communities were recruited across Manitoba using printed flyers, community organizations, and social media. Individual interviews, conducted in English, French, Mandarin, Cantonese, Tagalog, Arabic, Swahili, and Tigrinya languages, explored questions relating to sexual health and experiences with service providers. Data were analyzed using reflexive thematic analysis and socio-ecological systems theory. Results: The study uncovered a range of individual, interpersonal, institutional, and socio-structural factors that affect the sexual health of migrants in Manitoba. Individual factors such as sexual health knowledge and testing practices, interpersonal factors like the type of sexual partnerships, institutional factors such as sexual health information needs, language, and service access barriers, and structural-level factors like gender norms and HIV stigma exerted a significant influence on the sexual health practices of study respondents. Sexual health awareness was influenced by various factors including length of time in Canada and involvement in community-based services. Study respondents identified issues related to access to HIV testing and sexual health information, as well as language barriers, racism in healthcare, and HIV stigma. Gender and social norms played a significant role in discouraging communication about sex and safer sex practices. Conclusions: The study highlights the complex interplay of factors that influence the sexual health of migrants, and the need for targeted sexual health awareness campaigns and provision of sexual health information in languages spoken by migrants. Public health interventions focused on improving the sexual health outcomes for migrants should consider the socio-ecological elements identified in this study. These findings can inform public health campaigns to increase access to services and address sexual health inequities among migrant communities in Canada. [ABSTRACT FROM AUTHOR]

This paper extends analyses of the declining social assistance participation rate in Canada since the mid-1990s using rich Manitoba administrative data for the period since 1999. We examine trends in Manitoba to mid-2008, separately analyze the entry and continuation rates, and include for the first time information about the growing number of adults with a disability on social assistance. Our results show that the declining participation rate is due entirely to a declining entry rate and that the continuation rate has actually risen since 1999, mainly because of the dramatic growth in the number of adults with a disability on social assistance but also because of the rising duration of spells on assistance by those without a disability. Our results raise questions about the policy, pursued in all jurisdictions in Canada, that keeps social assistance benefits low to discourage welfare use. [ABSTRACT FROM AUTHOR]

This paper presents a methodology for assessing spatial and temporal uncertainty associated with flood risk management. Traditional modelling approaches focus on either temporal or spatial variability, but not both. There is a need to understand the dynamic characteristics of flood risk and its spatial variability. The traditional two-dimensional (2D) fuzzy set, with one dimension for the universe of discourse and the other dimension for its membership degree, is not sufficient to handle both, spatial and temporal variation of flood risk. The theoretical foundation of this study is based on the development of a three-dimensional (3D) fuzzy set that includes flood risk variability in space and time. The proposed methodology extends the acceptance level of partial flood damage concept to a 3D representation and allows capturing change of decision makers' preferences in time and space. The main objective of the paper is to present an original methodology for flood risk management that is capable of (a) addressing uncertainty caused by spatial and temporal variability and ambiguity; (b) integrating objective and subjective risks; and (c) assisting flood management decision making based on a more detailed understanding of temporal and spatial variability of risk. Presented methodology is illustrated using the Red River flood of 1997 (Manitoba, Canada) as a case study. [ABSTRACT FROM AUTHOR]

There are a myriad of laws, regulations, and policies governing the operating weights and dimensions of trucks. In Canada and many northern states, these regulations form a continuum of basic limits, seasonal variations, and overweight/overdimension limits that are legally permitted. This paper deals with the seasonal aspects of weight limits (winter weight premiums and spring weight restrictions) governing trucking within and to and from the prairie region. This region encompasses Manitoba, Saskatchewan, and Alberta, and the northern tier states of Minnesota, North Dakota, and Montana. The paper presents results of research conducted for the transportation departments of the three prairie provinces and Public Works and Government Services Canada. It discusses existing winter weight premium and spring weight restriction regulations, as well as basic weight regulations in the region, and their technical rationale. It examines possibilities for using advanced technologies to help harmonize and rationalize seasonal truck size and weight regulations and enforcement practices, and identifies immediate opportunities for rationalization and harmonization of spring weight restrictions and winter weight premiums.

As a result of the colonization of Canada, Metis have faced many political and socioeconomic challenges, one of which is the lower educational achievement of Metis students vs other Canadian students. In this study, we examined whether full-time kindergarten (FTK) vs half-time kindergarten (HTK) was associated with improved educational outcomes for Metis students in Manitoba using linked, population-based administrative data from 1998/99-2012/13. The cohort included 271 FTK and 405 HTK Metis students. We used generalized linear models with binomial distribution to calculate predicted probabilities and risk ratios for the outcomes (assessments of numeracy and literacy in Grades 3, 7 and 8; student engagement in Grade 7; high school graduation). However, we observed no significant differences in outcomes between FTK and HTK students, suggesting that FTK is not sufficient to overcome the structural barriers to academic success Metis students may face.

This paper has two purposes. First, it documents the historical context of MINCOME, a Canadian guaranteed annual income field experiment (1974 to 1979). Second, it uses routinely collected health administration data and a quasi-experimental design to document an 8.5 percent reduction in the hospitalization rate for participants relative to controls, particularly for accidents and injuries and mental health. We also found that participant contacts with physicians declined, especially for mental health, and that more adolescents continued into grade 12. We found no increase in fertility, family dissolution rates, or improved birth outcomes. We conclude that a relatively modest GAI can improve population health, suggesting significant health system savings. [ABSTRACT FROM AUTHOR]

The Thompson Nickel Belt marks the boundary between the Archean Superior Province and the Trans-Hudson Orogen in Canada. It comprises Archean gneisses, and Paleoproterozoic rocks with metasediments and metavolcanites (Ospwagan Group) and intrusions. The gneisses are frequently migmatitic and host numerous pegmatites. The western belt boundary is a fault contact with the Kisseynew Domain of the Reindeer Zone. In the south, the transition zone between the belt and the Kisseynew Domain comprises granitoids and a detrital sequence (Grass River Group), part of which grades into turbidites in the Kisseynew Domain. The eastern belt boundary is a diffuse zone where the Archean east-west (E-W) structural trend changes into the north-northeast (NNE) trend of the belt. This paper presents U-Pb ages for granitoids and 207Pb/206Pb detrital zircon ages from the Ospwagan and Grass River groups. Ages and a comparison of events in the belt and in the eastern Reindeer Zone have major implications. The change from stable platform deposits to syn-tectonic filling and emplacement of mafic intrusions in the Ospwagan Group are attributed to the convergence between the Reindeer Zone and the Superior Province at 1891-1885 Ma. At ca. 1850 Ma, continuing convergence led to drowning of marginal basins of the Superior craton and to the development of a transpressive regime in the belt, the onset of which could be as old as ca. 1885 Ma. Metamorphic ages of 1818-1785 record closure of the Kisseynew basin and crustal thickening. Collision of the new continental block with the Superior Province was accommodated by transpression until 1750-1720 Ma. La ceinture de Thompson est située entre le Craton archéen du Supérieur et l'orogène paléoprotérozoïque du Trans-Hudson, au Canada. Elle comprend des gneiss archéens souvent migmatitiques, et des roches paléoprotéroïques, métasédiments et métavolcanites (Groupe Ospwagan), et intrusions. A l'ouest, une zone de faille marque le contact entre la ceinture et le domaine Kisseynew de la Zone de Reindeer. Vers le sud, cette zone de transition entre la ceinture et le domaine Kisseynew comprends des granitoïdes et une séquence détritique (Groupe Grass River), qui passe graduellement aux turbidites du domaine Kisseynew. Sur la bordure orientale de la ceinture, le grain structural E-W du Craton archéen se réoriente dans le grain NNE de la ceinture. Cet article présente des âges U-Pb pour différents granitoïdes et des âges 207Pb/206Pb pour les zircons détritiques des groupes Ospwagan et Grass River. Les âges et une comparaison des événements affectant la ceinture et l'est de la zone Reindeer ont des implications importantes. Dans le groupe Ospwagan, le passage de dépôts de type plate-forme à des dépôts syn-tectoniques, et l'intrusion de roches basiques, sont attribuées à la convergence entre la zone Reindeer et le Craton du Supérieur vers 1891-1885 Ma. Vers 1850 Ma, la convergence conduit à l'enfouissement des bassins de la marge du Craton et à un régime transpressif pouvant avoir débuté dès ca. 1885 Ma. La fermeture du bassin de Kisseynew et l'épaississement crustal sont enregistrés par des âges de métamorphisme entre 1818 et 1785 Ma. Le régime transpressif se poursuit jusqu'à ca. 1750-1720 Ma.

This paper discusses a portion of the findings of a mixed-methods study that examined the career patterns of senior educational administrators in public school divisions in Manitoba, Canada. Data based on the career paths of senior administrators from both a survey and interviews of senior administrators were analyzed and compared along three variables: (a) position; (b) context; and (c) sex. This paper reports the findings of one aspect of the study that asked senior administrators to provide advice to aspirants interested in becoming senior administrators. Findings suggest that in Manitoba context, sex, and position interact to create differences in career experiences. Overall, senior administrators enjoy their work, but encourage aspirants to seriously consider the personal and professional responsibilities and ramifications of moving in to a position of such public and political responsibility.

The use of fiber-reinforced composite materials for the construction and rehabilitation of civil engineering structures is relatively new. Structural members are routinely joined by bolted connections. Bolted connections are relatively easy to assemble and maintain, and are capable of transferring the high loads that typically occur in civil engineering structures. Currently there is a serious lack of knowledge on the behavior and design of bolted connections for fiber-reinforced composites. In light of this, a comprehensive experimental and analytical investigation was conducted at the University of Manitoba to study the behavior of bolted connections in composite materials appropriate for civil engineering applications. A total of 102 single-bolt connections were tested up to failure. The various parameters investigated were the width of the structural member, the edge distance, the thickness, and the direction of the fibers with respect to the applied load. The experimental program also included comprehensive material testing to determine the various in-plane material properties. This paper discusses the experimental program, test results, and various modes of failure as affected by the foregoing parameters. From the test results an analytical model and design procedure were developed as proposed in a companion paper. [ABSTRACT FROM AUTHOR]

McKenzie Seeds is a crown corporation owned by the people of Manitoba. In 1983, the company was rocked by a scandal involving its senior management. During the course of the controversy, George F. MacDowell resigned as chairman of the McKenzie Seeds board of directors. He subsequently wrote a pamphlet which attempted to provide a context for understanding events at McKenzie Seeds. This paper provides a brief history of the company and a discussion of MacDowell's pamphlet. A postscript provides information on some recent developments, which suggests that the issues raised by the scandal and identified in the pamphlet remain unresolved. [ABSTRACT FROM AUTHOR]

In Canada, a vast majority of urban Indigenous people face distinct challenges accessing and connecting to Indigenous cultural practices. Research has found that colonial policies and practices continue to disrupt and fracture traditional methods of passing down cultural teachings, including dispossession from traditional lands in which cultural practices are rooted. This disruption continues to affect the availability of educational programming by and with Indigenous people and in Indigenous languages. This research involves a multi-method approach to observe and engage with a land-based traditional drum-making program for Indigenous men in an urban center in Southwestern Manitoba. By participating, watching, and listening to the men within the workshops through unstructured observation, Sharing Circles, individual interviews, and photovoice, we aim to understand the impacts of land-based learning on Indigenous men's well-being. The study is designed in accordance with University and Tri-Agency ethical guidelines, integrating ownership, control, access and possession (OCAP), as well as the principles of respect, relevance, reciprocity, and responsibility within all phases of the research. The research is co-created by the university researchers, community collaborators, and other relevant stakeholders. [ABSTRACT FROM AUTHOR]

In the 1920s some 3,800 Mennonites who had settled in Manitoba in the 1870s left their farms to migrate to the Bustillos Valley of northern Mexico. While conflict over education was the main stimulus for the move, this paper argues that the migration also offered an opportunity to restore the system of land tenure Mennonites had practiced in Imperial Russia. Conservative Mennonites had reified a tsarist-imposed system of semi-communal land tenure, making it a requirement of faithful religious and social practice. These sensibilities were, however, incompatible with the land tenure system of the new Dominion of Canada giving rise to tension and conflict. When migration became a reality, conservative Mennonites sought to reestablish the colony and village tenure system by seeking a block sale of their individual lands in Manitoba and by purchasing land in Mexico under colony title, thereby restoring semi-communal land tenure.

The ascomycete, Sclerotinia sclerotiorum, has a broad host range and causes yield loss in dicotyledonous crops world wide. Genomic diversity was determined in a population of 127 isolates obtained from individual canola (Brassica napus) fields in western Canada. Genotyping with 39 simple sequence repeat (SSR) markers revealed each isolate was a unique haplotype. Analysis of molecular variance showed 97% was due to isolate and 3% due to geographical location. Testing of mycelium compatibility among 133 isolates identified clones of mutually compatible isolates with 86–95% similar SSR haplotype, whereas incompatible isolates were highly diverse. In the Province of Manitoba, 61% of isolates were compatible forming clones and stings of pairwise compatible isolates not described before. In contrast, only 35% of isolates were compatible in Alberta without forming clones and strings, while 39% were compatible in Saskatchewan with a single clone, but no strings. These difference can be explained by wetter growing seasons and more susceptible crop species in Manitoba favouring frequent mycelium interaction and more life cycles over time, which might also explain similar differences observed in other geographical areas and host crops. Analysis of linkage disequilibrium rejected random recombination, consistent with a self-fertile fungus, restricted outcrossing due to mycelium incompatibility, and only a single annual opportunity for genomic recombination during meiosis in the ascospore stage between non-sister chromatids in the rare event nuclei from different isolates come together. More probable sources of genomic diversity is slippage during DNA replication and point mutation affecting single nucleotides that accumulate and likely increase mycelium incompatibility in a population over time. A phylogenetic tree based on SSR haplotype grouped isolates into 17 sub-populations. Aggressiveness was tested by inoculating one isolate from each sub-population onto B. napus lines with quantitative resistance. Analysis of variance was significant for isolate, line, and isolate by line interaction. These isolates represent the genomic and pathogenic diversity in western Canada, and are suitable for resistance screening in canola breeding programs. [ABSTRACT FROM AUTHOR]

Abstract: This paper describes an algorithm that has been developed to process field data from two upward looking sonars, one high (546kHz) and one low (235kHz) frequency, a 2MHz current profiler and a monitoring station, to measure surface ice characteristics on the North Saskatchewan River in the north east of Edmonton, AB, Canada, during the 2009/2010 freeze-up season. The algorithm used to calculate pans/rafts drafts and lengths, and the surface ice concentration is described. The validity and the accuracy of this technique were tested and computed surface ice conditions are presented. For the purpose of examining the effects of hydro-meteorological conditions on measured pan characteristics, the freeze-up period was divided into three distinct stages depending on the measured surface ice concentration. Pan/raft drafts were found to range from 0.1 to 1.0m and pan/raft lengths from 0.6 to 8.0m. The sonar proved to be very accurate in detecting the exact surface ice conditions locally above the sonar beam. However, interpretation of the results can sometimes be challenging, especially when physical processes such as bridging affect local ice conditions. Therefore, additional visual observations (e.g. time lapse photography) of surface ice conditions are recommended to aid in the interpretation of sonar measurements. [Copyright &y& Elsevier]

Abstract: The Balloon-borne Experiment with a Superconducting Spectrometer (BESS) was flown from Lynn Lake, Manitoba, Canada in August, 2000, during the maximum solar modulation period, with an average residual atmospheric overburden of 4.3g/cm2. Precise spectral measurements of cosmic ray hydrogen isotopes from 0.178GeV/n to 1.334GeV/n were made during the 28.7h of flight. This paper presents the measured energy spectra and their ratio, 2H/1H. The results are also compared with previous measurements and theoretical predictions. [Copyright &y& Elsevier]

Abstract: An extensive research project is currently being carried out at the University of Manitoba, Canada, involving the development of glass fiber-reinforced polymer (GFRP) wind turbine towers. The towers consist of multi-cell segments, each segment constructed from eight filament wound cells jointed together with resin applied over their interface. The present paper mainly addresses the static and dynamic characteristics, such as failure static loads, modes of failure, fundamental frequencies and periods of such segmented composite towers. Both experimental and numerical results are presented. The experimental investigation involved the testing of two jointed scaled towers. These specimens had a total height of 4.88-m (16-ft) and were tested as cantilevers under static and dynamic loading. The testing was conducted at the W.R. McQuade Structural Engineering Laboratory of the University of Manitoba. Finally, finite element models were developed to analyze the structural behavior, static and dynamic, of single and multi-cell composite segments and towers. The results from the finite element models under static loading were validated through comparison with the experimental results. [Copyright &y& Elsevier]

Abstract: Blowing snow is a frequent and significant winter weather event, and there is currently a need for more observations and measurements of blowing snow, especially in arctic and subarctic environments. This is the first paper in a two part series studying blowing snow in Churchill, Manitoba, and Franklin Bay, NWT. In this part, the development and use of a camera system to measure the shape, size and velocity of blowing snow particles is described. This system was used, along with standard meteorological instruments and optical particle counters, during field campaigns at Churchill, MB, which took place in March, 2005 and December, 2006. Measurements of blowing snow particle shape demonstrate that blowing snow particles are generally non-spherical, with an average ratio of the longest particle profile length to the perpendicular width of 1.41. Measurement of particle velocity with the camera system is shown to be inaccurate. However, measurements of particle number correlate well (r 2 =0.85) with simultaneous measurements made with a particle counter at the same height as the camera. The particle size distributions generally follow a Gamma distribution, with an average shape parameter of α =1.9. The shape parameter, α, shows no trend with height. The blowing snow particle number density decreases with height as approximately N ∝ z −1.4. The blowing snow particle number densities, interpolated to a height of 0.1 m, are in the range of 1.4×105 < N <4.7×107 m−3. Particle number densities are shown to generally increase over a limited range of wind speeds, corresponding to 10-m wind speeds in the range of 13< U 10 <17 m s−1. Over this range of wind speeds, the average particle size at a given height does not change significantly with wind speed. However, at a lower wind speed of U 10 ≈9 m s−1, the average particle size is generally smaller. Particle sizes generally decrease with height between 0.06 and 1 m. Above 0.2 m, the average particle diameters found in this study (120 µm< d―<154 µm) are similar to or generally larger than the range of sizes found in previous studies. Below 0.15 m, the average particle diameters in this study (103 µm< d―<172 µm) are similar to or generally smaller than the sizes found in previous studies. There is a large variation in the mean particle sizes of this and other studies, suggesting that particle sizes may be dependent on a number of other factors, such as upwind snow conditions and surface characteristics.

Abstract: Blowing snow is a frequent and significant winter weather event, and there is currently a need for more observations and measurements of blowing snow, especially in arctic and subarctic environments. This paper is the second part in a two part series studying blowing snow in Churchill, Manitoba, and Franklin Bay, NWT. In this part, the development and use of a camera system to measure the relative blowing snow density profile near the snow surface is described. This system has been used, along with standard meteorological instruments and optical particle counters, during a field campaign at Franklin Bay, NWT. A best-fit to the mass density profile in the saltation layer is derived, assuming a half-normal distribution of the vertical ejection velocity of saltating particles. Within the saltation layer, the observed vertical profile of mass density is found to be proportional to the function exp(− 0.61z/h̄), where h̄ is the average height of the saltating particles. For the range of conditions studied, h̄ varies from 1.0 to 10.4 mm, while the extent of the saltation layer varies from 17 to over 85 mm. There is a weak correlation between h̄ and the square of friction velocity. There are weak negative correlations between h̄ and temperature and relative humidity. No correlation is seen between h̄ and the snow age. At greater heights, z >0.2 m, the blowing snow density varies according to a power law (ρ s ∝z − γ), with a negative exponent 0.5<γ<3. Between these saltation and suspension regions, results suggest that the blowing snow density decreases following a power law with an exponent possibly as high as γ≈8. [Copyright &y& Elsevier]

The housing difficulties facing many low income Canadians today is well documented. For newcomers, and particularly refugees, these challenges may be amplified. This paper considers the influence of legal status and place in the housing outcomes of government-assisted refugees and refugee claimants in Vancouver, BC and Winnipeg, MB. Results from the study indicate that while claimants in Vancouver face a more difficult 'pathway to permanent housing' than do government-assisted refugees, the same is not true in Winnipeg. More alarmingly, certain refugee groups face barriers beyond legal status and place, owing to characteristics of the group itself. [ABSTRACT FROM AUTHOR]

Abstract: Accuracy in population estimation from individual measurement has been traditionally a research focus in both theoretical and applied ecology. In forest sciences, estimation of productivity and value recovery of forest products is essential for decision-making to achieve the goal of sustainable forest management. In this paper, we review the basic structure of data in forest sciences, describe commonly used statistical procedures in obtaining population estimates, and examine the accuracy associated with the forest products value estimation using forest inventory data of Manitoba, Canada. Our results suggested that simplified statistical procedures could bring about a wide range of bias in estimating lumber value recovery at the stand level, and improved understanding of stand structure and its reconstruction through computer simulation could be essential in reducing the bias involved in the estimation.

The article discusses how changes in programs for child health benefits in Manitoba, Canada affected the labor market and family health. The authors comment on changes to benefit programs intended to increase employment of mothers. They note how the Canada Child Tax Benefit was modified to include the National Child Benefit, in which state governments could deduct the National Child Benefit Supplement (NCBS), a cash benefit offered by the federal government, from welfare checks. The benefits encouraged welfare recipients to seek employment and helped improve family budgets. Manitoba offered an exemption from clawbacks for children that improved child development.

By many measures of health, Canada's First Nations compare very poorly to the non- Native population as a whole. The need to explain, and to correct, this disparity has led public health researchers to consider a wide variety of community characteristics. One area that is as yet under-utilized, but may yield important insights into the complex question of First Nations health, is history. This paper presents an overview of the potential uses of historical methods in the study of the health of First Nations communities in Manitoba. It also introduces the major historical data sources available to public health researchers involved in such research. There are three main benefits to the inclusion of history in public health research. First, we may learn about the impact of health changes on Aboriginal groups in the past. Second, we may better understand the origins of presentday health concerns, many of which emerged out of the events of the recent or not so recent past. Finally, we may gain important insights into the nature of the disease process, and the diseases themselves, by employing the past as a laboratory. The addition of an historical approach can enhance health research directed towards First Nations communities in Manitoba. [ABSTRACT FROM AUTHOR]

Background: Electronic Medical Records (EMRs) are a rich data source to measure and improve quality of care. As Canadian primary health care (PHC) EMRs mature, there is increasing potential use of EMR data for performance measurement. This study identifies and describes current uses of EMR data for performance measurement and considerations to further its potential in the Canadian context.Methods: We applied a qualitative case study design and descriptive assessment in three phases, consulting multiple data sources including scientific and grey literature, system leaders (n = 41), and clinician/researchers (n = 20). Phases included a multimethod approach to identify initiatives using EMR data for performance measurement across Canadian jurisdictions; in-depth review of current initiatives identified from a healthcare performance intelligence lens; and triangulation and thematic analysis across data sources to explore considerations for advancing performance measurement uses of EMR data in the Canadian context.Results: Six initiatives of EMR data use for performance measurement were identified: one multi-jurisdictional; five jurisdiction-specific in the provinces of British Columbia, Manitoba and Ontario. EMR data uses were predominately for micro-level PHC physician and team performance improvement, with some use for meso-level organization/network-wide improvement. Indicator sets varied in number, though shared emphasis on chronic disease management and prevention/screening and to a lesser extent medication management. Key considerations for governing, resourcing and implementing EMR data for performance measurement were identified.Conclusions: The extent of EMR data use for performance measurement varies across Canada. To further its potential, pan-Canadian data and privacy standards, performance intelligence competencies and renewed core PHC indicators should be prioritized. Experiences across countries, coupled with increasing momentum for performance measurement using real-world data, should be leveraged to avoid unnecessarily slow progress in Canada and abroad.

Individuals with cancer are vulnerable to infection with SARS-CoV-2, the virus causing COVID-19. Physical distancing, the reallocation of health care resources, and the implementation of procedures to reduce the spread of COVID-19 may also have serious consequences for people with cancer. We evaluated the impact of COVID-19 on new cancer diagnoses and oncology care in Manitoba, Canada using an interrupted time series design and data from the Manitoba Cancer Registry and CancerCare Manitoba's (CCMB) electronic medical record. In April 2020, there was a 23% decrease in new cancer diagnoses, a 21% decrease in pathology reports, and a 43% reduction in surgical resections. There was no difference in new cancer diagnoses by August 2020, surgery by July 2020, and pathology reports by September 2020. From April 2020 to June 2021, there was a 13% decrease in radiotherapy (RT) fractions, an 18% decrease in UCC visits, and a 52% decrease in in-person visits. There was no change in intravenous chemotherapy visits per month, first RT visits, or overall patient visits. The impact of COVID-19 on shifts in the stage at diagnosis and survival will be assessed in future analyses. [ABSTRACT FROM AUTHOR]

It is shown that the hourly ambient temperature and load of a substation transformer in Manitoba, observed over the three-month winter or summer time window, are governed by the normal distribution, respectively, and they jointly follow the bivariate normal distribution. Based on this, a rigorous model for the peak-load ambient temperature (i.e., the ambient temperature at the time when the winter or summer peak-load of the transformer occurs) is developed. This makes it possible to accurately determine the peak load capability of the transformer if its historical hourly ambient temperature and load data are available. [ABSTRACT FROM AUTHOR]

Middle Ordovician to Middle Devonian carbonates in the Manitoba lowlands form an extensive aquifer system along the eastern edge of the Williston Basin. The aquifer is divided into fresh and saline portions by a series of topographic lows defined by major river systems and lakes that create a north–south-trending hydraulic divide. East of this divide Ca–Mg–HCO[sub 3] fresh waters are derived by active modern-day recharge focused in the Sandilands and Interlake regions. Stable isotope and geochemical data indicate that Na–Cl saline waters west of the divide are a mixture of original basin brines and glacial melt water pushed into the basin during Pleistocene glaciation. High Na/Cl and Cl/Br ratios are consistent with significant salt dissolution by glacial melt water.Des carbonates datant de l'Ordovicien moyen au Dévonien moyen dans les basses terres du Manitoba forment un vaste système aquifère le long de la bordure est du bassin de Williston. L'aquifère est divisé en portions d'eau douce et d'eau salée par une série de creux topographiques définis par les grands systèmes de rivières et de lacs qui créent une ligne de partage des eaux à tendance nord–sud. À l'est de cette ligne de partage, les eaux douces Ca–Mg–HCO[sub 3] proviennent de recharges actives contemporaines concentrées dans les régions de Sandilands et d'Interlake. Des données géochimiques et d'isotopes stables indiquent que les eaux salées Na–Cl à l'ouest de la ligne de partage sont un mélange des saumures du bassin original et de l'eau de fonte glaciaire qui a été poussée dans le bassin au cours de la glaciation au Pléistocène. Des rapports Na/Cl et Cl/Br élevés concordent avec une grande dissolution de sel par les eaux de fonte glaciaire.[Traduit par la Rédaction] [ABSTRACT FROM AUTHOR]

Worldwide, Indigenous teens die by suicide and have more suicidal attempts than any other adolescent population and are overrepresented in every suicide statistic category. This study provides a new lens to look at Indigenous youth suicide through the perspectives of their parents, thereby giving them a voice in prevention and interventions. The findings of this qualitative study show that to help with their healing process, Indigenous parents require a connection to spirituality and culture, social supports, and an understanding that healing is lifelong, after the death or attempt of suicide by their child. Recommendations from this study are that Western systems adapt to focus on spirituality and culture in healing, as well as promote the destigmatization of suicide within Indigenous communities so that social supports can increase for parents who have experienced loss by suicide or suicide attempts by their children. In addition, professional helpers require more training in loss and grief, culturally relevant healing practices, and need to centre Indigenous knowledge in the creation of future intervention and postvention services.

In the transmission line grounding system design, spatial and temporal/seasonal variations of tower footing impedance should be considered. However, in real life, only spatial variations are taken into account at the design stage, seasonal variations have not been included. In this article, seasonal variations of tower footing impedance of several types of transmission line grounding systems at Manitoba Hydro, Canada, are investigated through field measurements for a whole year. The industrial practice uses simulated tower footing impedances by the software current distribution, electromagnetic interference, grounding and soil structure analysis (CDEGS) in the design of transmission line grounding systems, however, the accuracy of simulated tower footing impedances as a critical design parameter has never been evaluated. In this article, this industrial practice is evaluated by comparing simulated and measured tower footing impedances for various transmission line grounding systems. The importance to use proper tower footing impedance for lightning conditions is also demonstrated. [ABSTRACT FROM AUTHOR]
