    Full Text Available Abstract Background Although the incidence of serious morbidity with childhood pneumonia has decreased over time, empyema as a complication of community-acquired pneumonia continues to be an important clinical problem. We reviewed the epidemiology and clinical management of empyema at 8 pediatric hospitals in a period before the widespread implementation of universal infant heptavalent pneumococcal vaccine programs in Canada. Methods Health records for children Results 251 children met inclusion criteria; 51.4% were male. Most children were previously healthy and those ≤ 5 years of age comprised 57% of the cases. The median length of hospitalization was 9 days. Admissions occurred in all months but peaked in winter. Oxygen supplementation was required in 77% of children, 75% had chest tube placement and 33% were admitted to an intensive care unit. While similarity in use of pain medication, antipyretics and antimicrobial use was observed, a wide variation in number of chest radiographs and invasive procedures (thoracentesis, placement of chest tubes was observed between centers. The most common organism found in normally sterile samples (blood, pleural fluid, lung biopsy was Streptococcus pneumoniae. Conclusion Empyema occurs most commonly in children under five years and is associated with considerable morbidity. Variation in management by center was observed. Enhanced surveillance using molecular methods could improve diagnosis and public health planning, particularly with regard to the relationship between immunization programs and the epidemiology of empyema associated with community-acquired pneumonia in children.

    2009-11-01

    Full Text Available Abstract Background There is limited information in the literature on the presentation and prognosis of candidal urinary tract infection (UTI in infants in the neonatal intensive care unit (NICU. Methods This was a prospective cohort study performed in 13 Canadian NICUs. Infants with candidal UTI without extra-renal candidal infection at presentation were enrolled. Results Thirty infants fit the study criteria. Median birth weight and gestational age were 2595 grams (range 575-4255 and 35 weeks (range 24-41 with 10 infants being Conclusion Candidal UTI in the NICU population occurs both in term infants with congenital abnormalities and in preterm infants, and is associated with renal parenchymal disease and extra-renal dissemination. A wide variation in clinical approach was documented in this multicenter study. The overall mortality rate in these infants was significant (30%. In one third of the deaths, Candida infection was deemed to be a contributing factor, suggesting the need for antifungal therapy with repeat evaluation for dissemination in infants who are slow to respond to therapy.

    Full Text Available Abstract Background The seasonality, clinical and radiographic features and outcome of aseptic meningitis have been described for regional outbreaks but data from a wider geographic area is necessary to delineate the epidemiology of this condition. Methods A retrospective chart review was completed of children presenting with aseptic meningitis to eight Canadian pediatric hospitals over a two-year period. Results There were 233 cases of proven enteroviral (EV meningitis, 495 cases of clinical aseptic meningitis and 74 cases of possible aseptic meningitis with most cases occurring July to October. Headache, vomiting, meningismus and photophobia were more common in children ≥ 5 years of age, while rash, diarrhea and cough were more common in children Conclusion The clinical presentation of aseptic meningitis varies with the age of the child. Absence of CSF pleocytosis is common in infants

    The present study is a compilation of published data on coal facies studies in Canada based on coal petrological and other methods. The geological age of the coals range from the Devonian coal deposits in Arctic Canada to coals of Tertiary age in the Western Canada Sedimentary Basin, intermontane British Columbia and Arctic Canada. In terms of rank, the coal deposits studied range from lignite to low volatile bituminous. Coal petrological methods include maceral and microlithotype analyses, frequently integrated with data from palynological and geochemical analyses. Most recently, a number of studies have applied sequence stratigraphic concepts to the coal-bearing strata including the interpretation of coal petrological data in the context of this concept.

    2016-09-01

    Full Text Available The pillared layer motif is a commonly used route to porous coordination polymers or metal organic frameworks (MOFs. Materials based on the pillared cyano-bridged architecture, [Ni’(LNi(CN4]n (L = pillar organic ligands, also known as PICNICs, have been shown to be especially diverse where pore size and pore functionality can be varied by the choice of pillar organic ligand. In addition, a number of PICNICs form soft porous structures that show reversible structure transitions during the adsorption and desorption of guests. The structural flexibility in these materials can be affected by relatively minor differences in ligand design, and the physical driving force for variations in host-guest behavior in these materials is still not known. One key to understanding this diversity is a detailed investigation of the crystal structures of both rigid and flexible PICNIC derivatives. This article gives a brief review of flexible MOFs. It also reports the crystal structures of five PICNICS from our laboratories including three 3-D porous frameworks (Ni-Bpene, NI-BpyMe, Ni-BpyNH2, one 2-D layer (Ni-Bpy, and one 1-D chain (Ni-Naph compound. The sorption data of BpyMe for CO2, CH4 and N2 is described. The important role of NH3 (from the solvent of crystallization as blocking ligands which prevent the polymerization of the 1-D chains and 2-D layers to become 3D porous frameworks in the Ni-Bpy and Ni-Naph compounds is also addressed.

  12. Contaminant transport in fracture networks with heterogeneous rock matrices. The Picnic code

    2001-02-01

    In the context of safety assessment of radioactive waste repositories, complex radionuclide transport models covering key safety-relevant processes play a major role. In recent Swiss safety assessments, such as Kristallin-I, an important drawback was the limitation in geosphere modelling capability to account for geosphere heterogeneities. In marked contrast to this limitation in modelling capabilities, great effort has been put into investigating the heterogeneity of the geosphere as it impacts on hydrology. Structural geological methods have been used to look at the geometry of the flow paths on a small scale and the diffusion and sorption properties of different rock materials have been investigated. This huge amount of information could however be only partially applied in geosphere transport modelling. To make use of these investigations the 'PICNIC project' was established as a joint cooperation of PSI/Nagra and QuantiSci to provide a new geosphere transport model for Swiss safety assessment of radioactive waste repositories. The new transport code, PICNIC, can treat all processes considered in the older geosphere model RANCH MD generally used in the Kristallin-I study and, in addition, explicitly accounts for the heterogeneity of the geosphere on different spatial scales. The effects and transport phenomena that can be accounted for by PICNIC are a combination of (advective) macro-dispersion due to transport in a network of conduits (legs), micro-dispersion in single legs, one-dimensional or two-dimensional matrix diffusion into a wide range of homogeneous and heterogeneous rock matrix geometries, linear sorption of nuclides in the flow path and the rock matrix and radioactive decay and ingrowth in the case of nuclide chains. Analytical and numerical Laplace transformation methods are integrated in a newly developed hierarchical linear response concept to efficiently account for the transport mechanisms considered which typically act on extremely

  14. Reminder of the conditions of use for CERN’s picnic areas

    CERN Multimedia

    2014-01-01

    With summer on the way, we would like to remind you of some basic rules for the use of CERN’s picnic areas. Two picnic areas are available for the organisation of CERN events: • the Meyrin barbecue area in the clubs area (9405-R-000); • the Prévessin barbecue area located near to Building 972 (9401-R-000). These areas can be reserved through Indico: • 9405-R-000; • 9401-R-000. For all events taking place at weekends or on public holidays, a list of participants must be sent to the Fire Brigade (Fire.Brigade@cern.ch) and the Access Control Service (Access.Surveillance@cern.ch) for safety reasons. A request form has been created for this purpose (available here). The same services must be informed of events organised on weekdays, but a list of participants is not required in this case.

    2017-01-01

    The mysteries of the novel Picnic at Hanging Rock, by Joan Lindsay (1967, and its film adaptation of same name, directed by Peter Weir (1975, have been intriguing readers and audiences for more than four decades. Set in the Australian countryside in 1900, both narratives illustrate the Australian Gothic genre by revolving around the mystery of the disappearance of three schoolgirls and a teacher from a repressive boarding school during a picnic at the mountain. Basing our approach on the reflections by Linda Hutcheon (2011 on adaptations we analyze to which extent literary and cinematographic works relate to each other, while the works presented by Susan Bassnett (2006 and Kristi Siegl (2004 on women’s travel writing will allow us to approach themes such as female sexuality and travel as a metaphor of transformation.

  17. Renewing the Study of Public Sector Unions in Canada

    Directory of Open Access Journals (Sweden)

    2005-09-01

    Full Text Available A renewal of the study of public sector unionism in Canada is long overdue. This article explains why public sector unions deserve more attention from researchers than they have received of late and proposes that studies of public sector unions would benefit from adopting a new theoretical framework that conceptualizes contemporary unions as not only labour relations institutions but also as particular kinds of working-class movement organizations within a historically-specific class formation. It also identifies two obstacles to the production of accounts of contemporary public sector unions from this perspective.

    Bray, Garth M; Huggett, Deanna L

    2016-01-01

    The National Population Health Study of Neurological Conditions, a partnership between Neurological Health Charities Canada and the Government of Canada, was the largest study of neurological diseases, disorders, and injuries ever conducted in Canada. Undertaken between 2009 and 2013, the expansive program of research addressed the epidemiology, impacts, health services, and risk factors of 18 neurological conditions and estimated the health outcomes and costs of these conditions in Canada through 2031. This review summarizes highlights from the component projects of the study as presented in the synthesis report, Mapping Connections: An Understanding of Neurological Conditions in Canada. The key findings included new prevalence and incidence estimates, documentation of the diverse and often debilitating effects of neurological conditions, and identification of the utilization, economic costs, and current limitations of related health services. The study findings will support health charities, governments, and other stakeholders to reduce the impact of neurological conditions in Canada.

    We have measured and analyzed the dark data of two PICNIC IR arrays (P574 and P560) obtained through the Cosmic Infrared Background ExpeRiment (CIBER). First, we identified three types of bad pixels: the cold, the hot, and the transient, which are figured in total as 0.06% for P574 and 0.19% for P560. Then, after the bad pixels were masked, we determined the dark noise to be 20.5 ± 0.05 e- and 16.1 ± 0.05 e-, and the dark current to be 0.6 ± 0.05 e-/sec and 0.7 ± 0.05 e-/sec for P574 and P560, respectively. Finally, we discussed glitches and readout modes for a future mission.

    A study to examine the feasibility of establishing a Regional Specimen Bank in the Great Lakes area of the United States and Canada has recently been initiated by the Michigan Audubon Society. There are several existing formal and informal specimen banking facilities active in the region but their combined adequacy has not been evaluated. This feasibility study will establish the need and use of a regional bank and the institution(s) necessary to satisfy this need will be recommended. The study will address the scope required to meet present and future needs including the types of specimens to be represented in the bank, geographic coverage and protocols for collection, shipping, processing, analysis and storage. A management policy of the bank will be developed encompassing business operation, costs, governing structure and personnel requirements. The legal requirements of the bank will be determined with regards to the acquisition of samples, transport across national boundaries, access to specimens and information, and liability during operation. An effective information dissemination network will be recommended that is compatible with national and international partners, will facilitate technology and information transfer and support the quality and status of the bank. Determination of secure, long-term funding sources will be one of the key elements to ensuring a safe repository. This feasibility study is funded by the Great Lakes Protection Fund.

  4. Emergy accounting for regional studies: case study of Canada and its provinces.

    Science.gov (United States)

    Hossaini, Navid; Hewage, Kasun

    2013-03-30

    Sustainable regional management (development) requires an understanding of interactions between the social, economic, and ecological systems within the boundaries of a region. In this paper, application of emergy (an environmental accounting method) for regional planning is discussed through a case study. Emergy (spelled with an "m") methodology is an environmental accounting technique that evaluates the energy system for the thermodynamics of an open system. Major renewable and non-renewable resource fluxes to a region, including energy, matter, human activities, and money can be converted to emergy by using corresponding transformity functions. As a case study, this paper discusses the emergy accounting of Canada and its provinces with various emergy-based indicators. Moreover, emergy maps were generated in a form of emergy geography. These maps are multi-dimensional illustrations that show resource consumption, emergy per person, and emergy density across Canada under two parameters: (1) the quantities of resources consumed and (2) the location of consumption. Emergy analysis also highlights concentrations of renewable and natural resources in Canada and distinguishes the provinces with the highest resource consumption. Analysis of emergy indicator for Canadian provinces shows that Alberta with the highest EYR (7.35) provides energy to the economy of Canada. However, ELR value of Alberta (8.5) indicates that the province's current economic approach is not sustainable as it relies mainly on non-renewable emergy inputs (mainly from fossil fuels). ELR of British Columbia and Manitoba indicates that these two provinces created a firm balance between emergy use of renewable and non-renewable resources. The characterizations of regions provided in this paper can be used for future land planning and management both in federal and provincial levels.

  5. A Statistical Comparative Study of the Working Poor in Japan and Canada

    2011-01-01

    Full Text Available Problem statement: Recently in Japan, there has been an increase in the group which is termed the ‘Working Poor’. However, the group’s size and configuration remains unknown. Approach: The purpose of this study is to compare the working poor in Canada and Japan using microdata. First, the definition and method of estimation of the working poor provided by (Iwai and Murakami, 2007 are provided along with later modifications. Second, results of the investigation into data appropriate for use in estimating Canada’s working poor and poverty line are given, as are estimates of Canada’s working poor. Last, the characteristics of unemployment, unstable employment and the labor market are examined for both Canada and Japan and the similarities and differences between the two countries are highlighted. Results: In Canada and Japan, the working poor are most likely to be found among the young, those with a low level of education, those in unstable employment or those working in a company having few employees. As regards the differences between the two countries, males are more likely to be the working poor than females in Canada, though this trend is not seen in Japan; moreover, the percentage of the working poor is high among the 25-34 and 35-44 age groups in Japan, though this is not the case in Canada. Conclusion: As conclusions of this study, the first challenge that lies ahead is to find data from the two countries that allows a more rigorous comparison. The second challenge is to re-evaluate estimates made to date after a full investigation of labor market systems. Statistical Analysis Research Project (2009, we have estimated the working poor of the UK and compared their figures with those of Japan. The third challenge is thus to add the findings of this study to those from the UK/Japan and thereby perform a trilateral comparison.

    Kronick, Rachel; Rousseau, Cécile; Cleveland, Janet

    2015-05-01

    Children and parents seeking asylum are regularly detained in Canada, however little is known about the experiences of detained families. International literature suggests that the detention of children is associated with significant morbidity. Our study aims to understand the experiences of detained children and families who have sought asylum in Canada by using a qualitative methodology that includes semistructured interviews and ethnographic participant observation. Detention appears to be a frightening experience of deprivation that leaves children feeling criminalized and helpless. Family separation further shatters children's sense of well-being. Children's emotional and behavioral responses to separation and to detention suggest that the experience is acutely stressful and, in some cases, traumatic--even when detention is brief. Distress and impairment may persist months after release. Given the burden of psychological suffering and the harmful consequences of separating families, children should not be detained for immigration reasons and parents should not be detained without children.

    Full Text Available This study compares judgments of the fairness of economic actions among survey populations in Switzerland, and both student and non-student groups in the People's Republic of China, with the earlier Kahneman, Knetsch and Thaler (1986a surveys of Canadians. The findings suggest that fairness concerns matter among all of these groups, and the general patterns of what was and was not considered to be fair were similar. However, there were also some significant differences with the influence of fairness being weaker in the two Chinese samples than in the groups from the Western countries, with the influence being weakest in the Chinese student population for the wage related topics. On the whole, almost no significant gender differences were found in any of the new surveys.

  5. Mount Meager Volcano, Canada: a Case Study for Landslides on Glaciated Volcanoes

    Mount Meager is a strato-volcano massif in the Northern Cascade Volcanic Arc (Canada) that erupted in 2350 BP, the most recent in Canada. To study the stability of the Massif an international research project between France ( Blaise Pascal University), Italy (University of Turin) and Canada (Simon Fraser University) and private companies (TRE - sensing the planet) has been created. A complex history of glacial loading and unloading, combined with weak, hydrothermally altered rocks has resulted in a long record of catastrophic landslides. The most recent, in 2010 is the third largest (50 x 106 m3) historical landslide in Canada. Mount Meager is a perfect natural laboratory for gravity and topographic processes such as landslide activity, permafrost and glacial dynamics, erosion, alteration and uplift on volcanoes. Research is aided by a rich archive of aerial photos of the Massif (1940s up to 2006): complete coverage approximately every 10 years. This data set has been processed and multi-temporal, high resolution Orthophoto and DSMs (Digital Surface Models) have been produced. On these digital products, with the support on field work, glacial retreat and landslide activity have been tracked and mapped. This has allowed for the inventory of unstable areas, the identification of lava flows and domes, and the general improvement on the geologic knowledge of the massif. InSAR data have been used to monitor the deformation of the pre-2010 failure slope. It will also be used to monitor other unstable slopes that potentially can evolve to catastrophic collapses of up to 1 km3 in volume, endangering local communities downstream the volcano. Mount Meager is definitively an exceptional site for studying the dynamics of a glaciated, uplifted volcano. The methodologies proposed can be applied to other volcanic areas with high erosion rates such as Alaska, Cascades, and the Andes.

    As leaders calling for the conservation of the world's plants, botanical gardens protect plants within living collections. Many also study, manage and restore plants in natural habitats. Royal Botanical Gardens (Ontario,Canada) has integrated both horticultural and natural heritage in its mission for decades. Envisioned by municipal leaders in the 1920s as a combination of nature sanctuaries and civic gardens, RBG now includes forests, wetlands and other habitats, gardens and built spaces. Today RBG is Canada's largest botanical garden on the basis of area.In the 1950s RBG began to inventory plant diversity. The checklist of spontaneous vascular plants now exceeds 1 170 species, of which 752 are native. This is 37% of Ontario's native vascular plants and 19% of the native vascular flora of Canada. The RBG nature sanctuaries are among the richest locations in Canada for species-level diversity.We examine the history of fioristic exploration within RBG and compare plant species-area relationships among protected natural areas in Ontario. This comparison supports the contention that the nature sanctuaries, and in particular Cootes Paradise, could be considered an important area for plants in Canada, and relative to the nation's flora, a biodiversity hotspot. The fact that a candidate vascular plant hotspot for Canada lies within a major botanical garden presents opportunities for raising public awareness of the importance of plant diversity, as well as focusing attention on the scientific and conservation biology needs of communities and individual species in this area.

    High energy prices and greenhouse gases reduction represent the main challenges the current worldwide energetic situation has to face. As a consequence, paradox strategies can be highlighted: oil prices are sufficiently high to exploit non conventional oil resources, like extra heavy oils and oil sands. But the production of these resources emits larger GHG than the conventional oil path and implies other major environmental issues (water management, risks of soil pollution, destruction of the boreal forest), incompatible with the rules validated by the protocol of Kyoto. At the light of the new greenhouse gases reduction regulation framework announced by the Canadian Federal government, this work focuses on the study of greenhouse gases reduction alternatives applied to the non conventional oil sands exploitation in Canada.

    Successfully managing fisheries and controlling the spread of invasive species depends on the ability to describe and predict angler behavior. However, finite resources restrict conventional survey approaches and tend to produce retrospective data that are limited in time or space and rely on intentions or attitudes rather than actual behavior. In this study, we used three years of angler data from a popular mobile fishing application in Alberta, Canada, to determine province-wide, seasonal patterns of (1) lake popularity that were consistent with conventional data and (2) anthropogenic lake connectivity that has not been widely described in North America. Our proof-of-concept analyses showed that mobile apps can be an inexpensive source of high-resolution, real-time data for managing fisheries and invasive species. We also identified key challenges that underscore the need for further research and development in this new frontier that combines big data with increased stakeholder interaction and cooperation.

    Full Text Available There is an emerging literature describing the use of knowledge translation strategies to increase the relevance and usability of research, yet there are few real-world examples of how this works in practice. This case study reports on the steps taken to embed knowledge translation strategies in the Movember Foundation's Men’s Mental Health Grant Rounds in 2013–14, which were implemented in Australia and Canada, and on the support provided to the applicants in developing their knowledge translation plans. It identifies the challenges faced by the Men’s Mental Health Program Team and how these were resolved. The strategies explored include articulating knowledge translation requirements, ensuring a common understanding of knowledge translation, assessing knowledge translation plans, methods of engaging end users, and building capacity with applicants. An iterative approach to facilitating knowledge translation planning within project development was rolled out in Australia just prior to Canada so that lessons learned were immediately available to refine the second roll out. Implementation included the use of external knowledge translation expertise, the development of knowledge translation plans, and the need for internal infrastructure to support monitoring and reporting. Differences in the Australian and Canadian contexts may point to differential exposure to the concepts and practices of knowledge translation. This case study details an example of designing and implementing an integrated knowledge translation strategy that moves beyond traditional dissemination models. Lessons learned point to the importance of a long lead-up time, the use of knowledge translation expertise for capacity building, the need for flexible implementation, and the need for efficiencies in supporting applicants.

    The present study was aimed to study the requirements of bioequivalence for the registration of pharmaceutical products in the USA, Europe and Canada. Before going into bioequivalence studies it is essential for the pharmaceutical industry to study the guidelines of bioequivalence for the respective country where the industry wants to market its products and thus enter into generic market. This study reviews the requirements of bioequivalence with study parameters such as study design, fasting or fed state studies, volunteers recruitment, study dose, sampling points, analytical method validation parameters, moieties to be measured in plasma, pharmacokinetic parameters, criteria for bioequivalence, GCP requirements etc, which are needed for the pharmaceutical industry to carry out bioequivalence studies and to file ANDA. Test products and reference products are needed for this study. Test products are usually manufactured by a sponsor and reference products are provided by the government laboratories of the respective countries. Sampling points also vary with respect to the regulatory guidelines of these countries. All these countries follow ICH GCP guidelines. The criterion of bioequivalence for these countries is 90% CI 80-125% for C max, AUC t , AUC0-∞.

    Aim. To assess the effect of various lifestyle risk factors on the risk of salivary gland cancer in Canada using data from a population-based case-control study. Methods. Data from a population-based case-control study of 132 incident cases of salivary gland cancer and 3076 population controls were collected through self-administered questionnaire and analysed using unconditional logistic regression. Results. Four or more servings/week of processed meat product was associated with an adjusted odds ratio (OR) and corresponding 95% confidence interval (CI) of 1.62 (1.02–2.58). Nonsignificantly increased ORs were also related to obesity, >7 drinks/week of alcohol consumption, and occupational exposure to radiation. Furthermore, nonsignificantly decreased ORs were found to be associated with high education level (>12 years) (OR = 0.65), high consumption of spinach/squash (OR = 0.62) and all vegetables/vegetable juices (OR = 0.75), and >30 sessions/month of recreational physical activity (OR = 0.78). Conclusions. This study suggests positive associations with consumption of processed meat, smoking, obesity, alcohol drinking, and occupational exposure to radiation as well as negative associations with higher education, consumption of spinach/squash, and physical activity, which suggest a role of lifestyle factors in the etiology of salivary gland cancer. However, these findings were based on small number of cases and were nonsignificant. Further larger studies are warranted to confirm our findings. PMID:28133481

This pattern is changing with increased life expectancy, a growing population, and a poor social environment that influences risk behaviors, metabolic conditions, and disparities in screening uptake. These factors alone do not fully explain differences in cancer risk between populations, as genetic susceptibility and environmental factors also have significant influence.

    The objective of this study is to provide accurate, georeferenced maps of benthic habitats to assist in the siting of a new wastewater treatment plant outfall and the assessment of habitats of endangered, threatened, and economically important species. The mapping was conducted in the fall of 1999 using two complementary techniques: side-scan sonar and underwater videography. Products derived from these techniques include geographic information system (GIS) compatible polygon data of substrate type and vegetation cover, including eelgrass and kelp. Additional GIS overlays include underwater video track line data of total macroalgae, selected macroalgal species, fish, and macroinvertebrates. The combined tools of geo-referenced side-scan sonar and underwater video is a powerful technique for assessing and mapping of nearshore habitat in Puget Sound. Side-scan sonar offers the ability to map eelgrass with high spatial accuracy and resolution, and provides information on patch size, shape, and coverage. It also provides information on substrate change and location of specific targets (e.g., piers, docks, pilings, large boulders, debris piles). The addition of underwater video is a complementary tool providing both groundtruthing for the sonar and additional information on macro fauna and flora. As a groundtruthing technique, the video was able to confirm differences between substrate types, as well as detect subtle spatial changes in substrate. It also verified information related to eelgrass, including the density classification categories and the type of substrate associated with eelgrass, which could not be determined easily with side- scan sonar. Video is also a powerful tool for mapping the location of macroalgae, (including kelp and Ulva), fish and macroinvertebrates. The ability to geo-locate these resources in their functional habitat provides an added layer of information and analytical potential.

  17. Users' perspectives of barriers and facilitators to implementing EHR in Canada: A study protocol

    2009-04-01

    Full Text Available Abstract Background In Canada, federal, provincial, and territorial governments are developing an ambitious project to implement an interoperable electronic health record (EHR. Benefits for patients, healthcare professionals, organizations, and the public in general are expected. However, adoption of an interoperable EHR remains an important issue because many previous EHR projects have failed due to the lack of integration into practices and organizations. Furthermore, perceptions of the EHR vary between end-user groups, adding to the complexity of implementing this technology. Our aim is to produce a comprehensive synthesis of actual knowledge on the barriers and facilitators influencing the adoption of an interoperable EHR among its various users and beneficiaries. Methods First, we will conduct a comprehensive review of the scientific literature and other published documentation on the barriers and facilitators to the implementation of the EHR. Standardized literature search and data extraction methods will be used. Studies' quality and relevance to inform decisions on EHR implementation will be assessed. For each group of EHR users identified, barriers and facilitators will be categorized and compiled using narrative synthesis and meta-analytical techniques. The principal factors identified for each group of EHR users will then be validated for its applicability to various Canadian contexts through a two-round Delphi study, involving representatives from each end-user groups. Continuous exchanges with decision makers and periodic knowledge transfer activities are planned to facilitate the dissemination and utilization of research results in policies regarding the implementation of EHR in the Canadian healthcare system. Discussion Given the imminence of an interoperable EHR in Canada, knowledge and evidence are urgently needed to prepare this major shift in our healthcare system and to oversee the factors that could affect its adoption and

    Full Text Available City governments around the world are developing and expanding how they connect to citizens. Technologies play an important role in making this connection, and one frequent way that cities connect with citizens is through 311-style request systems. 311 is a non-emergency municipal notification system that uses telephone, email, web forms, and increasingly, mobile applications to allow citizens to notify government of infrastructure issues and make requests for municipal services. In many ways, this process of citizen contribution mirrors the provision of volunteered geographic information, that is spatially-referenced user generated content. This research presents a case study of the city of Edmonton, Canada, an early adopter of multi-channel 311 service request systems, including telephone, email, web form, and mobile app 311 request channels. Three methods of analysis are used to characterize and compare these different channels over three years of request data; a comparison of relative request share for each channel, a spatial hot spot analysis, and regression models to compare channel usage with sociodemographic variables. The results of this study indicate a shift in channel usage from traditional to Internet-enabled, that this shift is mirrored in the hotspots of request activity, and that specific digital inequalities exist that reinforce this distinction between traditional and Internet-enabled reporting channels.

    Based on high-resolution pollen records from lake cores in central Canada, the present study instructed pollen taxa assignations in ecosystem groups and modern analogue technique, reported major results of quantitative reconstructions of vegetation history during the last 1000 years, and discussed the validation of simulated vegetation. The results showed that in central America (115°-95°W,40°-60°N), best analogue of the modern vegetation is 81% for boreal forest, 72% for parkland, and 94% for grassland-parkland, which are consistent with vegetation distributions of the North American Ecosystem Ⅱ. Simulations of the past vegetation from the sedimentary pollen showed climate changes during the past 1000 years: it was warm and dry in the Medieval Warm period, cold and wet in the earlier period and cold and dry in the later period of the Little Ice Age. It became obviously increasing warm and drought in the 20th century. The present studies would provide us scientific basis to understand vegetation and climate changes during the last 1000 years in a characteristic region and in 10-100 year time scales.

    2012-09-01

    Blackfoot field, Alberta, Canada, has produced oil and gas from a Glauconitic compound incised valley-system. In this area channels can be filled with sands and/or shales. Differentiation of prospective channel sands and non-productive shales was always problematic due to the similarity in P-wave impedance of these two lithotypes. We study the spectral decomposition response to the hydrocarbons presence in the Glauconitic channel of Early Cretaceous age. From previous AVO analysis and modeling, a strong Class III AVO anomaly has been observed at the top of the porous sandstone in the upper valley, whereas shale had a very different AVO response. Furthermore, AVO inversion revealed additional information about lithology and fluid content in the channel. Our workflow starts from selecting a continuous horizon that was close and conforms to the channel interval; we then run spectral analyses for the channel area. Short Window Fourier Transform workflow could successfully image the channel's stratigraphic features and confirm results obtained from AVO analysis and inversion run on the data before being stacked. Additionally, the producing oil wells in the sand-fill channel were found to be correlating with high spectrum amplitude; while the dry wells in the shale-plugged channel fell in low amplitude anomaly.

    One hundred and ten cases of suicidal suffocation using a plastic bag were identified in the files of the Office of the Chief Coroner of Ontario, Canada, between 1993 and 1997. The records were reviewed to determine the demographic characteristics of this group compared with all cases of suicide in Ontario, the scene information, autopsy findings and toxicology results. Most suicides occurred in people over 60 years of age, with older women making up a considerable proportion of cases as compared with other methods of suicide. In 40% of cases the deceased was suffering from a serious illness. Autopsy findings were usually minimal, with facial, conjunctival and visceral petechiae present in a minority of cases. One or more drugs were detected in the blood in 92.6% of cases where toxicologic testing was performed. Benzodiazepines, diphenhydramine and antidepressants were the most common drugs found, with diphenhydramine the most common drug present at an elevated concentration. Information at the scene from "right to die" societies was uncommon. One quarter of decedents took additional measures, besides the use of drugs or alcohol, to ensure the rapidity, certainty or comfort of their death. This study further elucidates the characteristics of this uncommon method of suicide. It emphasizes additional scene findings, such as the presence of dust masks, physical restraints and modification of the plastic bag that may be of use to death investigators in determining the correct manner of death.

    This study examined the relationships between culture and the health status of older Chinese in Canada. Data were collected through face-to-face interviews with a cross-sectional, randomly selected sample of 2,272 older Chinese between 55 and 101 years of age in seven Canadian cities. Health status was assessed by the number of chronic illnesses, by limitations in ADL and IADL, and by information on the Medical Outcome Study Short Form SF-36. Although cultural variables explained only a small proportion of variance in health status, having a stronger level of identification with traditional Chinese health beliefs was significant in predicting physical health, number of illnesses, and limitations on IADL. Other cultural variables, including religion, country of origin, and length of residence in Canada, were also significant in predicting some health variables. Interventions to improve health should focus on strategies to enhance cultural compatibility between users and the health delivery system.

    Full Text Available Abstract Background The effect of antioxidants on breast cancer is still controversial. Our objective was to assess the association between antioxidants and breast cancer risk in a large population-based case-control study. Methods The study population included 2,362 cases with pathologically confirmed incident breast cancer (866 premenopausal and 1,496 postmenopausal and 2,462 controls in Canada. Intakes of antioxidants from diet and from supplementation as well as other potential risk factors for breast cancer were collected by a self-reported questionnaire. Results Compared with subjects with no supplementation, 10 years or longer supplementation of zinc had multivariable-adjusted odds ratios (OR and 95% confidence intervals (CI of 0.46 (0.25-0.85 for premenopausal women, while supplementation of 10 years or longer of multiple vitamin, beta-carotene, vitamin C, vitamin E and zinc had multivariable-adjusted ORs (95% CIs of 0.74 (0.59, 0.92, 0.58 (0.36, 0.95, 0.79 (0.63-0.99, 0.75 (0.58, 0.97, and 0.47 (0.28-0.78, respectively, for postmenopausal women. No significant effect of antioxidants from dietary sources (including beta-carotene, alpha-carotene, lycopene, lutein and zeaxanthin, vitamin C, vitamin E, selenium and zinc or from supplementation less than 10 years was observed. Conclusions This study suggests that supplementation of zinc in premenopausal women, and supplementation of multiple vitamin, beta-carotene, vitamin C, vitamin E and zinc in postmenopausal women for 10 or more years may protect women from developing breast cancer. However, we were unable to determine the overall effect of total dose or intake from both diet and supplement.

    A total of 309 Mississippi Valley Population Canada geese, Branta canadensis interior, of different sex and age groups was collected from three locations in the Mississippi Flyway from 1979-1981 and examined for gizzard nematodes and renal coccidia. Three species of nematodes were removed from the gizzards, Amidostomum anseris, A. spatulatum, and Epomidiostomum crami. The latter two species are reported from this population of geese for the first time. Gizzard nematodes were found in 95.2% of all Canada geese examined, with A. anseris being the most abundant of the three species. There was no statistically significant difference between immatures and adults in the abundance of total nematodes species however, immature geese carried significantly more A. anseris and adult geese harbored significantly more A. spatulatum and E. crami infections. No significant difference in gizzard worm infections between male and female birds was observed. The abundance of overall gizzard nematodes was greatest in Canada geese from Winisk, Ontario (11.9), but the abundance of worms in southern Illinois geese (10.0) was similar. Geese from Horicon National Wildlife Refuge had the lowest abundance of infection, 7.5. The overall abundance of nematodes showed a general increase the second year of the study in each sex and age group and at each collection area. Each of three species of nematodes was responsible for some degree of damage to the gizzard lining and koilin, but E. crami was the most pathogenic of the species recovered. The occurrence of renal coccidiosis in Canada geese of this flyway is reported for the first time; the etiologic agent is Eimeria clarkei. The oocysts and/or endogenous stages of E. clarkei were present in 6.8% of the Canada geese sampled and this was the only species found. Male and female geese showed no significant differences in E. clarkei infections, however, significantly more immature geese than adult geese were infected with this species. A cell

    Dental disease is important in the population of pets seen by veterinarians. Knowledge and skills related to oral disease and dentistry are critical entry-level skills expected of graduating veterinarians. A descriptive survey on the state of veterinary dental education was sent to respondents from 35 veterinary schools in the United States, Canada, and the Caribbean. Using the online SurveyMonkey application, respondents answered up to 26 questions. Questions were primarily designed to determine the breadth and depth of veterinary dental education from didactic instruction in years 1-3 to the clinical year programs. There was an excellent response to the survey with 86% compliance. Learning opportunities for veterinary students in years 1-3 in both the lecture and laboratory environments were limited, as were the experience in the clinical year 4, which were divided between community-type practices and veterinary dentistry and oral surgery services. The former provided more hands-on clinical experience, including tooth extraction, while the latter focused on dental charting and periodontal debridement. Data on degrees and certifications of faculty revealed only 12 programs with board-certified veterinary dentists. Of these, seven veterinary schools had residency programs in veterinary dentistry at the time of the survey. Data from this study demonstrate the lack of curricular time dedicated to dental content in the veterinary schools participating in the survey, thereby suggesting the need for veterinary schools to address the issue of veterinary dental education. By graduation, new veterinarians should have acquired the needed knowledge and skills to meet both societal demands and professional expectations.

    This article draws on the vast evidence that suggests, on one hand, that socioeconomic inequalities in health are present in every society in which they have been measured and, on the other hand, that the size of inequalities varies substantially across societies. We conduct a comparative case study of the United States and Canada to explore the role of neoliberalism as a force that has created inequalities in socioeconomic resources (and thus in health) in both societies and the roles of other societal forces (political, economic, and social) that have provided a buffer, thereby lessening socioeconomic inequalities or their effects on health. Our findings suggest that, from 1980 to 2008, while both the United States and Canada underwent significant neoliberal reforms, Canada showed more resilience in terms of health inequalities as a result of differences in: (a) the degree of income inequality, itself resulting from differences in features of the labor market and tax and transfer policies, (b) equality in the provision of social goods such as health care and education, and (c) the extent of social cohesiveness across race/ethnic- and class-based groups. Our study suggests that further attention must be given to both causes and buffers of health inequalities.

    Background: In Canada, interferon-free, direct-acting antiviral hepatitis C virus (HCV) regimens are costly. This presents challenges for universal drug coverage of the estimated 220 000 people with chronic HCV infection nationwide. The study objective was to appraise criteria for reimbursement of 4 HCV direct-acting antivirals in Canada. Methods: We reviewed the reimbursement criteria for simeprevir, sofosbuvir, ledipasvir-sofosbuvir and paritaprevir-ritonavir-ombitasvir plus dasabuvir in the 10 provinces and 3 territories. Data were extracted from April 2015 to June 2016. The primary outcomes extracted from health ministerial websites were: 1) minimum fibrosis stage required, 2) drug and alcohol use restrictions, 3) HIV coinfection restrictions and 4) prescriber type restrictions. Results: Overall, 85%-92% of provinces/territories limited access to patients with moderate fibrosis (Meta-Analysis of Histologic Data in Viral Hepatitis stage F2 or greater, or equivalent). There were no drug and alcohol use restrictions; however, several criteria (e.g., active injection drug use) were left to the discretion of the physician. Quebec did not reimburse simeprevir and sofosbuvir for people coinfected with HIV; no restrictions were found in the remaining jurisdictions. Prescriber type was restricted to specialists in up to 42% of provinces/territories. Interpretation: This review of criteria of reimbursement of HCV direct-acting antivirals in Canada showed substantial interjurisdictional heterogeneity. The findings could inform health policy and support the development and adoption of a national HCV strategy. PMID:28018873

    Primary care physicians can serve as both facilitators and barriers to cancer screening, particularly for under-screened groups such as immigrant patients. The objective of this study was to inform physician-targeted interventions by identifying primary care physician characteristics associated with cancer screening for their eligible patients, for their eligible immigrant patients, and for foreign-trained physicians, for their eligible immigrant patients from the same world region. A population-based retrospective cohort study was performed, looking back 3 years from 31 December 2010. The study was performed in urban primary care practices in Ontario, Canada's largest province. A total of 6303 physicians serving 1,156,627 women eligible for breast cancer screening, 2,730,380 women eligible for cervical screening, and 2,260,569 patients eligible for colorectal screening participated. Appropriate breast screening was defined as at least one mammogram in the previous 2 years, appropriate cervical screening was defined as at least one Pap test in the previous 3 years, and appropriate colorectal screening as at least one fecal occult blood test in the previous 2 years or at least one colonoscopy or barium enema in the previous 10 years. Just fewer than 40% of physicians were female, and 26.1% were foreign trained. In multivariable analyses, physicians who attended medical schools in the Caribbean/Latin America, the Middle East/North Africa, South Asia, and Western Europe were less likely to screen their patients than Canadian graduates. South Asian-trained physicians were significantly less likely to screen South Asian women for cervical cancer than other foreign-trained physicians who were seeing region-congruent patients (adjusted odds ratio: 0.56 [95% confidence interval 0.32-0.98] versus physicians from the USA, Australia and New Zealand). South Asian patients were the most vulnerable to under-screening, and decreasing patient income quintile was consistently

    Full Text Available Abstract Background An aging population, rise in chronic illnesses, increase in life expectancy and shift towards care being provided at the community level are trends that are collectively creating an urgency to advance hospice palliative care (HPC planning and provision in Canada. The purpose of this study was to analyze the evolution of HPC in seven provinces in Canada so as to inform such planning and provision elsewhere. We have endeavoured to undertake this research out of awareness that good future planning for health and social care, such as HPC, typically requires us to first look backwards before moving forward. Methods To identify key policy and practice events in HPC in Canada, as well as describe facilitators of and barriers to progress, a qualitative comparative case study design was used. Specifically, the evolution and development of HCP in 7 strategically selected provinces is compared. After choosing the case study provinces, the grey literature was searched to create a preliminary timeline for each that described the evolution of HPC beginning in 1970. Key informants (n = 42 were then interviewed to verify the content of each provincial timeline and to discuss barriers and facilitators to the development of HPC. Upon completion of the primary data collection, a face-to-face meeting of the research team was then held so as to conduct a comparative study analysis that focused on provincial commonalities and differences. Results Findings point to the fact that HPC continues to remain at the margins of the health care system. The development of HPC has encountered structural inheritances that have both sped up progress as well as slowed it down. These structural inheritances are: (1 foundational health policies (e.g., the Canada Health Act; (2 service structures and planning (e.g., the dominance of urban-focused initiatives; and (3 health system decisions (e.g., regionalization. As a response to these inheritances, circumventions

    Full Text Available Abstract Background Facilitating the provision of appropriate health care for immigrant and Aboriginal populations in Canada is critical for maximizing health potential and well-being. Numerous reports describe heightened risks of poor maternal and birth outcomes for immigrant and Aboriginal women. Many of these outcomes may relate to food consumption/practices and thus may be obviated through provision of resources which suit the women's ethnocultural preferences. This project aims to understand ethnocultural food and health practices of Aboriginal and immigrant women, and how these intersect with respect to the legacy of Aboriginal colonialism and to the social contexts of cultural adaptation and adjustment of immigrants. The findings will inform the development of visual tools for health promotion by practitioners. Methods/Design This four-phase study employs a case study design allowing for multiple means of data collection and different units of analysis. Phase 1 consists of a scoping review of the literature. Phases 2 and 3 incorporate pictorial representations of food choices (photovoice in Phase 2 with semi-structured photo-elicited interviews (in Phase 3. The findings from Phases 1-3 and consultations with key stakeholders will generate key understandings for Phase 4, the production of culturally appropriate visual tools. For the scoping review, an emerging methodological framework will be utilized in addition to systematic review guidelines. A research librarian will assist with the search strategy and retrieval of literature. For Phases 2 and 3, recruitment of 20-24 women will be facilitated by team member affiliations at perinatal clinics in one of the city's most diverse neighbourhoods. The interviews will reveal culturally normative practices surrounding maternal food choices and consumption, including how women negotiate these practices within their own worldview and experiences.

    Parks and green space areas are important to human health for psychological and physiological reasons. There have been few evaluations of access to green space on mortality. This paper describes a cohort study of approximately 575,000 adults, 35 years of age and older, who resided in 10 urban areas in Ontario, Canada, between 1982 and 1986. Individuals were identified from income tax filings, and vital status was determined up to December 31, 2004 through record linkage to the Canadian Mortality Data Base. Place of residence was defined by postal code data that were extracted from income tax filings. Urban green space was defined by Landsat satellite retrievals with the Normalized Difference Vegetation Index and this was assigned to individuals' place of residence at inception into the cohort using both a 30 m grid cell and a 500 m buffer. The proportional hazards model was used to estimate rate ratios (RRs) and their corresponding 95% confidence intervals (CI) for selected underlying causes of death. The rate ratios were adjusted for income, marital status, ambient air pollution, and contextual neighborhood characteristics. About 187,000 subjects died during follow-up. An increase in the interquartile range of green space, using a 500 m buffer, was associated with reduced non-accidental mortality (RR=0.95, 95% CI=0.94-0.96). Reductions in mortality with increased residential green space were observed for each underlying cause of death; the strongest association was found for respiratory disease mortality (RR=0.91, 95% CI=0.89-0.93). Risk estimates were essentially unchanged after adjusting for ambient air pollution. Our study suggests that green space in urban environments was associated with long-term reduction in mortality although this finding should be interpreted cautiously as this association may be influenced by residual confounding of sociodemographic and lifestyle factors. Further research is needed to: confirm these findings, better understand the

    The 1.85 Ga Sudbury Igneous Complex (SIC), Ontario, Canada, is an intrusive complex representing the crystallized melt sheet that formed within a large impact crater. The SIC has been extensively studied due to its rich endowment in magmatic sulfide ores (Ni-Cu-PGEs). The nature and origin of the SIC melt sheet and its subsequent evolution still remain controversial. In this study, analyses of primary melt inclusions hosted in cumulus apatite within three mafic units of the SIC (gabbro, norite and sublayer quartz diorite) are used to decipher the thermometric and chemical characteristics of the evolving melt sheet as it crystallized. Apatite-hosted melt inclusions commonly display a negative crystal shape, occur parallel to the c-axis, and often occur within a central growth zone, which suggest a primary origin. The compositions of coeval (co-entrapped) melt inclusions are distinct and may represent either the products of immiscibility (low or high temperature field; c.f. the Skaergaard Intrusion: Jakobsen et al., Geology, 2005), or a product of early, high-temperature, impact-generated emulsification (prior to and independent of crystallization of the melt sheet). The compositions of homogenized (1100-1200oC for 3 hrs) melt inclusions, determined by SEM-EDS and EMP analyses of opened, homogenized melt inclusions, equate to two distinct compositions: (1) Type-I are SiO2-rich, ranging from tonalitic to granodioritic in composition (60-70 wt% SiO2, up to 11 wt% FeO); and (2) Type-II are Fe-rich with syenogabbroic to essexitic to alkali gabbroic compositions (27-49 wt% SiO2, 16-44 wt% FeO). Trace element data, obtained by LA-ICPMS analyses of single inclusions and surrounding host apatite, are used to infer D values between apatite and the two melt types, and between the coexisting melt types. Apparent Dap-melt values for both Type-I and Type-II inclusions show that the REE, Sr, and Y are compatible in apatite, and As is weakly compatible or incompatible in apatite

    Canada's first nurse practitioner-led clinic opened in 2007 after a period of intense lobbying. The development of this clinic has received a great deal of attention in the nursing world and among the general public, but the factors that enabled it have not been examined. The antecedents outlined in healthcare innovation concept analysis - including leadership, financial considerations, idea generation, teamwork, culture and demand - provide a framework for examination of the campaign for the nurse practitioner-led clinic. This review demonstrates the complex interplay of factors that drive healthcare innovation and expands understanding of the leadership and change competencies of the advanced practice nurse.

    To better understand background radiation levels in country foods, a total of 125 fish samples were collected from three lakes (Lake 226, Lake 302 and Lake 305) in the Experimental Lakes Area (ELA) in Ontario of Canada during the summer of 2014. Concentrations of naturally occurring radionuclides ((226)Ra, (210)Pb and (210)Po) as well as anthropogenic radionuclides ((134)Cs and (137)Cs) were measured. This study confirmed that (210)Po is the dominant contributor to radiation doses resulting from fish consumption. While concentrations of (210)Pb and (226)Ra were below conventional detection limits, (210)Po was measured in almost all fish samples collected from the ELA. The average concentration was about 1.5 Bq/kg fresh weight (fw). None of the fish samples analysed in this study contained any detectable levels of (134)Cs. An average (137)Cs level of 6.1 Bq/kg fw was observed in freshwater fishes harvested in the ELA, almost twice that of samples measured in the National Capital Region of Canada in 2014 and more than 20 times higher than the levels observed in marine fish harvested from the Canadian west coast in 2013 and 2014. However, it is important to note that the concentrations of (137)Cs in fish samples from these inland lakes are considered very low from a radiological protection perspective. The resulting radiation dose for people from fish consumption would be a very small fraction of the annual dose from exposure to natural background radiation in Canada. The results indicate that fishes from inland lakes do not pose a radiological health concern.

    During the late part of 2000 and early months of 2001, project veterinarians recruited 205 beef herds to participate in a study of the effects of emissions from the upstream oil and gas industry on cattle reproduction and health. Researchers developed herd-selection criteria to optimize the range of exposure to facilities, including oil and gas wells, battery sites, and gas-gathering and gas-processing facilities across the major cattle-producing areas of Western Canada. Herds were initially selected on the basis of a ranking system of exposure potential on the basis of herd-owner reports of the locations of their operations in relation to oil and gas industry facilities. At the end of the study, researchers summarized data obtained from provincial regulatory agencies on facility location and reported flaring and venting volumes for each herd and compared these data to the original rankings of herd-exposure potential. Through this selection process, the researchers were successful in obtaining statistically significant differences in exposure to various types of oil and gas facility types and reported emissions among herds recruited for the study.

    The emerald ash borer (EAB) poses a significant economic and environmental threat to ash trees in southern Ontario, Canada, and the northern states of the USA. It is critical that effective technologies are urgently developed to detect, monitor, and control the spread of EAB. This paper presents a methodology using multisourced data to predict potential infestations of EAB in the town of Oakville, Ontario, Canada. The information combined in this study includes remotely sensed data, such as high spatial resolution aerial imagery, commercial ground and airborne hyperspectral data, and Google Earth imagery, in addition to nonremotely sensed data, such as archived paper maps and documents. This wide range of data provides extensive information that can be used for early detection of EAB, yet their effective employment and use remain a significant challenge. A prediction function was developed to estimate the EAB infestation states of individual ash trees using three major attributes: leaf chlorophyll content, tree crown spatial pattern, and prior knowledge. Comparison between these predicted values and a ground-based survey demonstrated an overall accuracy of 62.5%, with 22.5% omission and 18.5% commission errors.

    Full Text Available Objectives: The objective was to examine the association between non-Hodgkin′s lymphoma (NHL and farming-related activities, gender, pesticides exposure, and exposure to chemicals other than pesticides in Saskatchewan. Materials and Methods: Male and female study participants were taken from two separate case-control studies conducted in Saskatchewan province, Canada. A case was defined as any man or woman aged 19 years and older with a first diagnosis of NHL registered by the Saskatchewan Cancer Agency during the study period. Conditional logistic regression was used to fit the statistical models. Results: Farming exposure and exposure to pesticides-contaminated cloths were related to an increased risk of NHL. Exposure to pesticides was strongly associated with an increased risk of NHL, especially for men. Conclusion: For men, the incidence of NHL was associated with exposure to pesticides after adjusting for other independent predictors.

    Full Text Available Although educating active citizen who participate in civic and political life is a fundamental goal of education, in general, and of citizenship education, in particular, there are very few empirical studies that inform us how the school educates for this purpose. This study, conducted in three Civics classrooms in Ontario, Canada, investigates how teachers prepare their students for active citizenship. Drawing on citizenship theories and an examination of citizenship pedagogy through observations of class instruction and interviews with teachers and students, the results of the study reveal that teachers’ understandings of what constitutes active citizenship greatly influence how they educate for active citizenship. I detail three distinct understandings of active citizenship that are advanced through class instruction: the duty-based, the make-a-difference and the politically-oriented active citizenship. The article discusses important implications that these differing understandings and pedagogical approaches have as they delineate different expectations and paths for youth citizenship participation in public life.

    Historically, salmon stocks from the Columbia River and Snake River formed one of the most valuable fisheries on the west coast of North America. However, salmon and steelhead returns sharply declined during the 1980s and 1990s to reach nearly 1 million fish. Although several factors may be responsible for the decline of Columbia River salmon and steelhead, there is increasing evidence that these drastic declines were primarily attributable to persistently unfavorable ocean conditions. Hence, an understanding of the effects of ocean conditions on salmon production is required to forecast the return of salmon to the Columbia River basin and to assess the efficacy of mitigation measures such as flow regulation on salmon resources in this system. The Canadian Program on High Seas Salmon has been collecting juvenile salmon and oceanographic data off the west coast of British Columbia and Southeast Alaska since 1998 to assess the effects of ocean conditions on the distribution, migration, growth, and survival of Pacific salmon. Here, we present a summary of the work conducted as part of the Canada-USA Salmon Shelf Survival Study during the 2008 fiscal year and compare these results with those obtained from previous years. The working hypothesis of this research is that fast growth enhances the marine survival of salmon, either because fast growing fish quickly reach a size that is sufficient to successfully avoid predators, or because they accumulate enough energy reserves to better survive their first winter at sea, a period generally considered critical in the life cycle of salmon. Sea surface temperature decreased from FY05 to FY08, whereas, the summer biomass of phytoplankton increased steadily off the west coast of Vancouver Island from FY05 to FY08. As in FY07, zooplankton biomass was generally above average off the west coast of Vancouver Island in FY08. Interestingly, phytoplankton and zooplankton biomass were higher in FY08 than was expected from the observed

    Against the backdrop of demographic change and economic reconfiguration, recruiting international students, especially those at tertiary level, has drawn growing attention from advanced economies as part of a broad strategy to manage highly skilled migration. This comparative study focuses on three English speaking countries receiving international students: Canada, the United States, and the United Kingdom. International student policies, in particular entry and immigration regulations, and the trends in student mobility since the late 1990s are examined drawing on secondary data. By exploring the issue from the political economy perspectives, this study identifies distinct national strategies for managing student mobility, determines key factors shaping the environment of student migration in each nation, and addresses the deficiency of human capital theory in the analysis of global competition for high skills.

    Attrition of experienced staff, falling student enrolments and closure of university courses are symptoms of the contraction of the Canadian nuclear industry over the last two decades. It is not alone. A study carried out by Human Resources Development Canada, a government department, to forecast the demand for qualified nuclear staff in Canada over the next 15 years has reached similar conclusions to an OECD/NEA study of its members` future personnel requirements.

    Organophosphate (OP) insecticides are commonly used in agriculture. Their use decreased in recent years as they were gradually replaced by other pesticides, but some OPs are still among the insecticides most used in Canada. Exposure to elevated levels of OPs during pregnancy has been associated with adverse birth outcomes and poorer neurodevelopment in children. The objective of the present study was to examine the relationship between the concentrations of OP pesticides urinary dialkyl phosphate (DAP) metabolites and various factors that are potential sources of exposure or determinants of DAP levels. In the Maternal-Infant Research on Environmental Chemicals (MIREC) Study, six DAPs were measured in 1st trimester urine samples of 1884 pregnant women living in Canada. They were grouped into sums of dimethyl alkyl phosphates (DMAP) and diethyl alkyl phosphates (DEAP) for statistical analysis. We found that 93% of women had at least one DAP detected in their urine. Geometric means (GM) of specific gravity-corrected levels for urine dilution were 59 (95% CI 56-62) and 21 (95% CI 20-22) nmol/L for DMAP and DEAP, respectively. The following characteristics were significantly associated with higher urinary concentrations of DMAP or DEAP: higher education, nulliparous, normal pre-pregnancy body mass index, non-smoker, not fasting at sampling, winter season at sampling, and early and late day collection times. Dietary items that were significantly related with higher urinary concentrations included higher intake of citrus fruits, apple juice, sweet peppers, tomatoes, beans and dry peas, soy and rice beverages, whole grain bread, white wine and green and herbal teas. This study indicates that exposure to these compounds is quasi-ubiquitous. The factors associated with greater DAP levels identified here could be useful to regulatory agencies for risk analysis and management. However, some exposure misclassification might occur due to the single DAP measurement available, and

    We investigated mercury (Hg) concentrations in small fish (mainly yellow perch, Perca flavescens; ∼60% of fish collected) and in blood of common loons (Gavia immer) that prey upon them during the breeding season on lakes in 4 large, widely separated study areas in Canada (>13 lakes per study area; total number of lakes = 93). Although surface sediments from lakes near a base metal smelter in Flin Flon, Manitoba had the highest Hg concentrations, perch and other small fish and blood of common loon chicks sampled from these same lakes had low Hg concentrations similar to those from uncontaminated reference lakes. Multiple regression modeling with AIC analysis indicated that lake pH was by far the most important single factor influencing perch Hg concentrations in lakes across the four study areas (R(2) = 0.29). The best model was a three-variable model (pH + alkalinity + sediment Se; Wi = 0.61, R(2) = 0.85). A single-variable model (fish Hg) best explained among-lake variability in loon chick blood Hg (Wi = 0.17; R(2) = 0.53). From a toxicological risk perspective, all lakes posing a potential Hg health risk for perch and possibly other small pelagic fish species (where mean fish muscle Hg concentrations exceeded 2.4 μg/g dry wt.), and for breeding common loons (where mean fish muscle Hg concentrations exceeded 0.8 μg/g dry wt., and loon chick blood Hg exceeded 1.4 μg/g dry wt.) had pH < 6.7 and were located in eastern Canada.

    The eugenics movement attracted a wide range of supporters. This article explores this theme with relation to literature about the charitable work of the Salvation Army in Britain and Canada c.1890-1921, with a focus upon the emigration scheme outlined in William Booth's book In Darkest England and the Way Out. These writings indicate the widespread dispersal of eugenic ideology, and demonstrate the flexibility with which these theories were interpreted in this period. It will be shown that the Salvation Army adopted elements of both hereditarian and environmentalist views regarding racial health. These arguments were unified by the claim that the work of the organization made a worthy contribution to public health, both in the present and in the future. This case study sheds new light upon the history of a prominent evangelical Christian organization and upon the development of the international eugenics movement.

    This presentation discussed the strategies and materials developed for a five-year study of the capacity of institutions in two dryland regions (the South Saskatchewan River Basin in western Canada and the Elqui River Basin of north-central Chile) to adapt to the impacts of climate change. The purpose of the project was to obtain a systematic and comprehensive understanding of the capacities of regional institutions to formulate and implement strategies of adaptation to climate change risks and the forecasted impacts of climate change on the supply and management of water resources in dryland environments. Both regions are at different stages of social and environmental vulnerability and yet have a dry climate adjacent to a major mountain system and landscapes at risk of desertification, as well as an agricultural economy dependent on irrigation water derived from mountain snow and glaciers. tabs., figs.

    A moratorium on further bivalve leasing was established in 1999-2000 in Prince Edward Island (Canada). Recently, a marine spatial planning process was initiated explore potential mussel culture expansion in Malpeque Bay. This study focuses on the effects of a projected expansion scenario on productivity of existing leases and available suspended food resources. The aim is to provide a robust scientific assessment using available datasets and three modelling approaches ranging in complexity: (1) a connectivity analysis among culture areas; (2) a scenario analysis of organic seston dynamics based on a simplified biogeochemical model; and (3) a scenario analysis of phytoplankton dynamics based on an ecosystem model. These complementary approaches suggest (1) new leases can affect existing culture both through direct connectivity and through bay-scale effects driven by the overall increase in mussel biomass, and (2) a net reduction of phytoplankton within the bounds of its natural variation in the area.

    Various environmental and socioeconomic issues have been attributed to land-use changes, and therefore, the underlying mechanisms merit investigation and quantification. This study assesses a comprehensive series of land-use conversions that were implemented over a recent 12-year period in the province of Alberta, Canada, where rapid economic and population growth has occurred. Spatial autocorrelation models are applied to identify the comprehensive effects of environmental and socioeconomic factors in each conversion case. The empirical results show that the impacts of key environmental and socioeconomic factors varied in intensity depending on the type of land-use conversion involved. Overall, land suitability for agricultural uses, road density, elevation, and population growth were found to be significant predictors of land-use changes. High land suitability, low elevation, and moderate road density were associated with land conversion for agricultural purposes.

    CIET started supporting Canadian Aboriginal community-based researchers of resilience in 1995. An evolving approach to Aboriginal resilience used a combination of standard instruments and questionnaires of local design. Over the years, CIET measured personal assets like sense of coherence, spirituality, knowledge, pride in one's heritage, mastery or self-efficacy, self-esteem, low levels of distress, involvement in traditional ways and activities, church attendance. Other indicators reflected the social dimension of resilience: feeling supported; parental care and support; parental monitoring, attitudes, and example; peer support; and support from the wider community.Pride in one's heritage, self-esteem, low distress, and mastery were measurable personal assets of resilient Aboriginal youth in a variety of cultures and circumstances. Early efforts to link resilience with specific features of culture or spirituality did not meet with success - largely reflecting failure to ask the right questions. Parental care and support, parental monitoring, parental attitudes, and parental example clearly supported the resilient Aboriginal youth in most settings. But peers are an even stronger influence, critical in relation to different types of behaviour from smoking to drinking to substance abuse to violence, unsafe sex, and suicidal tendencies. More generally, having someone to confide in, to count on in times of crisis, someone to give advice and someone who makes one feel cared for are important factors in youth resilience and something that communities can help to provide even where the family is not the support it should be and where peers are more of a hindrance than a help.CIET currently supports three resilience research projects involving Aboriginal youth in Canada: suicide prevention, reduction of HIV risk, and reduction of domestic violence. The latest resilience measurement tools include enculturation and revised approaches to Aboriginal spirituality.

    With technological innovation, comprehensive dietary intake data can be collected in a wide range of studies and settings. The Automated Self-Administered 24-h (ASA24) Dietary Assessment Tool is a web-based system that guides respondents through 24-h recalls. The purpose of this paper is to describe lessons learned from five studies that assessed the feasibility and validity of ASA24 for capturing recall data among several population subgroups in Canada. These studies were conducted within a childcare setting (preschool children with reporting by parents), in public schools (children in grades 5–8; aged 10–13 years), and with community-based samples drawn from existing cohorts of adults and older adults. Themes emerged across studies regarding receptivity to completing ASA24, user experiences with the interface, and practical considerations for different populations. Overall, we found high acceptance of ASA24 among these diverse samples. However, the ASA24 interface was not intuitive for some participants, particularly young children and older adults. As well, technological challenges were encountered. These observations underscore the importance of piloting protocols using online tools, as well as consideration of the potential need for tailored resources to support study participants. Lessons gleaned can inform the effective use of technology-enabled dietary assessment tools in research. PMID:28146125

    The impact of exposure to emissions from oil and gas field facilities on animal and human health has been a long-standing concern in western Canada. This technical summary presented highlights of the 17 major research appendices of a study examining associations between emissions and important reproductive parameters in beef cattle, including pregnancy rates, frequencies of abortions and stillbirths, and the risk of death among young calves. The effect of exposure to emissions on the respiratory, immune and nervous systems of calves and yearlings was also evaluated. The study was an epidemiological investigation that drew on large blocks of data collected from privately owned cow-calf operations, laboratory analyses of biological samples and samplers from air monitors. Mixed effect regression models were used to investigate whether measures of reproductive, immunological, and pathology outcomes were associated with emissions from the petroleum industry. Appropriate statistical adjustments were made to correct for multiple comparisons following standard statistical practice. An overview of the methods used to analyze the data was presented, as well as an examination of the methods of epidemiology in determining a causal effect, and the limitations of a single study in determining causation with certainty. Information on water quality testing and feeding management and forage testing was provided. 15 tabs., 26 figs.

    Despite significant needs, people on social assistance are sometimes reluctant to consult dentists because of previous negative experience and communication barriers. They feel poorly understood by oral health professionals and sometimes complain of being stigmatized. It is thus important to know how dentists perceive poverty and this group of patients. The aim of this study was to understand how dentists perceive poverty and people on social assistance. To investigate this largely unexplored question, a qualitative study was conducted based on in-depth interviews with thirty-three dentists practicing in Montreal, Canada. Interviews were audiotaped and transcribed for qualitative analysis. The study revealed two perspectives on poverty: 1) the individualistic-deficit perspective and 2) the socio-lifecourse perspective. In the individualistic-deficit perspective, which predominated among these participants, dentists explained poverty by individual factors and emphasized individuals' negative attitudes toward work and lack of capabilities. Conversely, dentists with a socio-lifecourse perspective described poverty as a structural rather than an individual process. Acknowledging individuals' distress and powerlessness, these dentists expressed more empathy toward people on social assistance. The results suggest the individualistic-deficit perspective impedes the care relationship between dentists and poor patients as well as highlighting the need to better prepare dentists for addressing issues of poverty and social inequities in clinical practice.

    Few studies have examined the acute cardiovascular effects of airborne allergens. We conducted a case-crossover study to evaluate the relationship between airborne allergen concentrations and emergency room visits for myocardial infarction (MI) in Ontario, Canada. In total, 17,960 cases of MI were identified between the months of April and October during the years 2004-2011. Daily mean aeroallergen concentrations (pollen and mold spores) were assigned to case and control periods using central-site monitors in each city along with daily measurements of meteorological data and air pollution (nitrogen dioxide and ozone). Odds ratios and their 95% confidence intervals were estimated using conditional logistic regression models adjusting for time-varying covariates. Risk of MI was 5.5% higher (95% confidence interval (CI): 3.4, 7.6) on days in the highest tertile of total pollen concentrations compared with days in the lowest tertile, and a significant concentration-response trend was observed (P pollen concentrations, with the largest risks being observed during May (odds ratio = 1.16, 95% CI: 1.00, 1.35) and June (odds ratio = 1.10, 95% CI: 1.00, 1.22), when tree and grass pollen are most common. Mold spore concentrations were not associated with MI. Our findings suggest that airborne pollen might represent a previously unidentified environmental risk factor for myocardial infarction.

    Introduction Models of depression that arise in the West need to be examined in other regions of the world. This study examined a set of foundational hypotheses generated by Beck’s cognitive model of depression among depressed individuals in Egypt and Canada. Method We recruited 29 depressed and 29 non-depressed Egyptians and compared their results with those of 35 depressed and 38 non-depressed Canadians. Depression status was ascertained using a structured interview, scores on the Beck Depression Inventory, and scores on the Psychiatric Diagnostic Screening Questionnaire. Participants completed questionnaires designed to measure the frequency of negative and positive automatic thoughts (ATQ–N, BHS, and ATQ–P), and dysfunctional attitudes (DAS). Results Depressed individuals in both countries had significantly more negative thoughts about self and future, greater frequency of dysfunctional attitudes, and diminished positive self-thoughts in comparison to non-depressed individuals. Egyptians generally showed significantly more dysfunctional attitudes than their Canadian counterparts. Discussion The four hypotheses that were tested were supported among the depressed Egyptian sample, which is consistent with the cognitive model. Implications for the cognitive-behavioral model and treatment for this group of sufferers are discussed. PMID:27010706

    Full Text Available Abstract Background Collaborative, culturally safe services that integrate clinical approaches with traditional Aboriginal healing have been hailed as promising approaches to ameliorate the high rates of mental health problems in Aboriginal communities in Canada. Overcoming significant financial and human resources barriers, a mental health team in northern Ontario is beginning to realize this ideal. We studied the strategies, strengths and challenges related to collaborative Aboriginal mental health care. Methods A participatory action research approach was employed to evaluate the Knaw Chi Ge Win services and their place in the broader mental health system. Qualitative methods were used as the primary source of data collection and included document review, ethnographic interviews with 15 providers and 23 clients; and 3 focus groups with community workers and managers. Results The Knaw Chi Ge Win model is an innovative, community-based Aboriginal mental health care model that has led to various improvements in care in a challenging rural, high needs environment. Formal opportunities to share information, shared protocols and ongoing education support this model of collaborative care. Positive outcomes associated with this model include improved quality of care, cultural safety, and integration of traditional Aboriginal healing with clinical approaches. Ongoing challenges include chronic lack of resources, health information and the still cursory understanding of Aboriginal healing and outcomes. Conclusions This model can serve to inform collaborative care in other rural and Indigenous mental health systems. Further research into traditional Aboriginal approaches to mental health is needed to continue advances in collaborative practice in a clinical setting.

    2016-04-01

    The Grand Lake Meadows is an important part of the Saint John River wetlands that form the largest freshwater wetland habitat in the Maritimes (eastern Canada). Changes in the land cover and use around wetlands significantly impact their biotic diversity, alter the ecosystem, and affect their ability to support human needs. The goal for this paper was to undertake a detailed and spatially explicit inventory of local trends in land use and land cover changes in Grand Lake Meadows over a 20-year time period. This goal was achieved through classifying historical remotely-sensed images to map the state of land use and cover. Other available data were combined with this information to create a database that was used to investigate the causes and consequences of changes. The results demonstrated the flexibility and the effectiveness of this technology in establishing the necessary baseline and support information for sustaining the eco-services of a wetland. The study identified a 38% decrease in the wetland from 1990 to 2001, while there was 80% increase in the wetland area since then. The result will help managers to comprehend the dynamics of the changes, prompting a better management and implementation of LULC administration in the area.

    Full Text Available Past silvicultural treatments have resulted in the high-grading mixed temperate forests of Québec, Canada. Despite recognition of this issue, the low occurrence of yellow birch (Betula alleghaniensis Britton within current stands raises questions about the potential of the species to grow and eventually constitute a high-quality forest resource. The objective of this study was to assess this potential using tree characteristics, forest structure and additional site and climatic conditions as predictors. A total of 145 trees were sampled in two areas located in the same bioclimatic zone. Lower-Saguenay-Charlevoix was chosen as an area where a restoration plan could be implemented, whereas Portneuf was selected as a reference. We used nonlinear mixed models to investigate which environmental factors are likely to influence the radial growth and stem quality of yellow birch sample trees. Our results suggest that topographic and climatic conditions, as well as the competitive environment of the trees, are important factors to consider in the evaluation of yellow birch production. Despite the limited occurrence of yellow birch, the potential for growth and quality was high in the Lower-Saguenay-Charlevoix area. For equivalent topographic, climatic, and competitive environment conditions, there was no significant difference in either radial growth or stem quality with Portneuf. We suggest that the economic interest of producing high quality timber should be used to justify the implementation of a restoration strategy in the Lower-Saguenay-Charlevoix area.

    Full Text Available Assessing moisture contents of lichens and mosses using ground-based high spectral resolution spectrometers (400–2500 nm offers immense opportunities for a comprehensive monitoring of peatland moisture status by satellite/airborne imagery. This information may be valuable for present and future carbon balance modeling. Previous studies are based upon point measurements of vegetation moisture content and water table position, and therefore a detailed moisture status of entire northern peatlands is not available. Consequently, upscaling ground and remotely sensed data to the desired spatial resolutions is inevitable. This study continues our previous investigation of the impact of various moisture conditions of common sub-Arctic lichen and moss species (i.e., Cladina stellaris, Cladina rangiferina, Dicranum elongatum, and Tomenthypnum nitens upon the spectral signatures obtained in the Hudson Bay Lowlands, Canada. Upscaling reflectance measurements of the above species were conducted in the field, and reflectance analysis using a singularity index was made, since this study serves as a basis for future aircraft/satellite research. An attempt to upscale current and new spectral reflectance indices developed in our previous studies was made as well. Our findings indicate that the spectral index C. rangiferina is to a lesser amount influenced by scale since it has a small R2 values between the log of the index and the log of the resolution, reduced slopes between the log of the index and the log of the resolution, and similar slopes between log reflectance and log resolution (α of two wavelengths employed by the index. Future study should focus on concurrent monitoring of moisture variations in lichens and mosses both in situ and from satellite and airborne images, as well as analysis of fractal models in relations to the upscaling experiments.

    The Mallik site represents an onshore permafrost-associated gas hydrate accumulation in the Mackenzie Delta, Northwest Territories, Canada. A gas hydrate research well was drilled at the site in 1998. The objective of this study is the analysis of various gas production scenarios from five methane hydrate-bearing zones at the Mallik site. In Zone #1, numerical simulations using the EOSHYDR2 model indicated that gas production from hydrates at the Mallik site was possible by depressurizing a thin free gas zone at the base of the hydrate stability field. Horizontal wells appeared to have a slight advantage over vertical wells, while multiwell systems involving a combination of depressurization and thermal stimulation offered superior performance, especially when a hot noncondensible gas was injected. Zone #2, which involved a gas hydrate layer with an underlying aquifer, could yield significant amounts of gas originating entirely from gas hydrates, the volumes of which increased with the production rate. However, large amounts of water were also produced. Zones #3, #4 and #5 were lithologically isolated gas hydrate-bearing deposits with no underlying zones of mobile gas or water. In these zones, thermal stimulation by circulating hot water in the well was used to induce dissociation. Sensitivity studies indicated that the methane release from the hydrate accumulations increased with the gas hydrate saturation, the initial formation temperature, the temperature of the circulating water in the well, and the formation thermal conductivity. Methane production appears to be less sensitive to the specific heat of the rock and of the hydrate, and to the permeability of the formation. ?? 2004 Published by Elsevier B.V.

    Successful applications of stochastic models for simulating and predicting daily stream temperature have been reported in the literature. These stochastic models have been generally tested on small rivers and have used only air temperature as an exogenous variable. This study investigates the stochastic modelling of daily mean stream water temperatures on the Moisie River, a relatively large unregulated river located in Québec, Canada. The objective of the study is to compare different stochastic approaches previously used on small streams to relate mean daily water temperatures to air temperatures and streamflow indices. Various stochastic approaches are used to model the water temperature residuals, representing short-term variations, which were obtained by subtracting the seasonal components from water temperature time-series. The first three models, a multiple regression, a second-order autoregressive model, and a Box and Jenkins model, used only lagged air temperature residuals as exogenous variables. The root-mean-square error (RMSE) for these models varied between 0.53 and 1.70 °C and the second-order autoregressive model provided the best results.A statistical methodology using best subsets regression is proposed to model the combined effect of discharge and air temperature on stream temperatures. Various streamflow indices were considered as additional independent variables, and models with different number of variables were tested. The results indicated that the best model included relative change in flow as the most important streamflow index. The RMSE for this model was of the order of 0.51 °C, which shows a small improvement over the first three models that did not include streamflow indices. The ridge regression was applied to this model to alleviate the potential statistical inadequacies associated with multicollinearity. The amplitude and sign of the ridge regression coefficients seem to be more in agreement with prior expectations (e.g. positive

    The objective of this study was to update a 2011 survey, conducted on behalf of the ESCMID Study Group for Antibiotic Policies (ESGAP), studying the availability of old but clinically useful antibiotics in North America, Europe and Australia. This follow-up survey was performed in 2015 in 40 countries among specialists from the pharmaceutical, infectious diseases and microbiology sectors in North America, Europe and Australia in order to assess the availability through usual marketing processes of 36 systemic antibiotics (addition of 3 antibiotics compared with the 2011 survey) selected for their ability to treat infections caused by resistant bacteria and their unique value for specific criteria. The questionnaire was sent by e-mail to national contacts belonging to ESGAP and ReAct networks. In all, 39 of the 40 countries participated in this survey. The number of available antibiotics differed considerably from one drug to another as well as from one country to another (e.g. 7 antibiotics available in Estonia, 24 in France). Overall, 25/36 selected antibiotics were marketed in 20/39 countries or less. From 2011 to 2015 (data available for both periods in 37 countries for 33 antibiotics), the number of available selected antibiotics increased in 13 countries and decreased in 17. In conclusion, despite the ongoing bacterial resistance crisis, the situation regarding the availability of 'forgotten antibiotics' has worsened since 2011. Urgent measures are needed to ensure better availability of these antibiotics on a global scale as a conservation measure to ensure sustainable and responsible use of antibiotics.

    Full Text Available Background. Routine vaccination against Streptococcus pneumoniae is recommended in Canada for infants, the elderly, and individuals with chronic comorbidity. National incidence and burden of all-cause and pneumococcal pneumonia in Canada (excluding Quebec were assessed. Methods. Incidence, length of stay, and case-fatality rates of hospitalized all-cause and pneumococcal pneumonia were determined for 2004–2010 using ICD-10 discharge data from the Canadian Institutes for Health Information Discharge Abstract Database. Population-at-risk data were obtained from the Statistics Canada census. Temporal changes in pneumococcal and all-cause pneumonia rates in adults ≥65 years were analyzed by logistic regression. Results. Hospitalization for all-cause pneumonia was highest in children 70 years and declined significantly from 1766/100,000 to 1537/100,000 per year in individuals aged ≥65 years (P<0.001. Overall hospitalization for pneumococcal pneumonia also declined from 6.40/100,000 to 5.08/100,000 per year. Case-fatality rates were stable (11.6% to 12.3%. Elderly individuals had longer length of stay and higher case-fatality rates than younger groups. Conclusions. All-cause and pneumococcal pneumonia hospitalization rates declined between 2004 and 2010 in Canada (excluding Quebec. Direct and indirect effects from pediatric pneumococcal immunization may partly explain some of this decline. Nevertheless, the burden of disease from pneumonia remains high.

  15. Educational reform and the public: Two case studies of Poland and Saskatchewan (Canada)

    Kaproń, Danuta; Stephan, Werner

    1991-09-01

    The involvement of the public in educational reform processes in modern democratic societies primarily serves the purpose of politically legitimizing the reform agenda. This study examines the rationales implicitly or explicitly submitted to the public to explain why educational reforms in the two countries should be endorsed. Although differences in the political culture caution against a hasty comparison of the two case studies, a number of politico-economic similarities allow for a valid juxtaposition. In Poland the context of socio-political and economic renewal prompted the reformers to emphasize the human-capital model which heightened public awareness and participation in the debate surrounding the reform. Public involvement in Saskatchewan was negatively affected for mainly two reasons. First, the government evidently manipulated public input by various means and thereby appears to have predetermined the outcome. Second, the rationale for the reform, based on a free-market model, tightened the linkage between the needs of the labour market and the mandate of the schools. As a result, public interest and participation was greatly diminished.

    This brief paper indicates that forest fires may have short and longer term effects on runoff and thus, can influence trend studies on the response of watersheds to climate change. Twenty-two watersheds at the Experimental Lakes Area in northwestern Ontario were studied to view the impacts of climatic variability and forest fires on runoff. A roughly 30 year database demonstrated few trends in climatological variables and even fewer trends in runoff data at the 5% significance level. Daily maximum temperature increased by 0.053 °C per year, while precipitation in the months of February and March showed significant decreases. Total snow showed a significant decrease over a 30 year period at the 8% significance level. The Mann Kendall test for trend was applied to the runoff indices of 19 watersheds and it was revealed that only six exhibited trends. Of these, five had been burned during the test period. Virtually all burned watersheds showed initial increases in runoff, however, long term runoff trended lower in the burned watersheds, while the one watershed that was not burned showed an increasing trend. Forest fires alter the age distribution of trees with subsequent impacts on water yields in the short and longer term.

    Varicella vaccine in immunocompromised children was clinically evaluated in 575 US and Canadian children with leukemia in remission by the Varicella Vaccine Collaborative Study. Most children had chemotherapy stopped 1 week before and 1 week after immunization. Steroids were stopped for 3 weeks (1 week before to 2 weeks after vaccination). Varicella vaccine was safe, immunogenic, and effective in leukemic children at risk for serious disease or death from chickenpox. The major side effect was mild rash in 50% approximately 1 month after immunization. About 40% of children who developed rash were treated with acyclovir. Vaccine efficacy was judged by the degree of protection after a household exposure to varicella; of 123 exposed children, 17 (14%) developed a mild form of varicella. The vaccine protected completely against severe varicella. Leukemic vaccines were less likely to develop zoster than were comparable children with leukemia who had wild type varicella. Thus, varicella vaccine, administered carefully with close follow-up, is extremely beneficial for leukemic children.

    Adverse associations between air pollution and myocardial infarction (MI) are widely reported in medical literature. However, inconsistency and sensitivity of the findings are still big concerns. An exploratory investigation was undertaken to examine associations between air pollutants and risk of acute MI (AMI) hospitalization in Alberta, Canada. A time stratified case-crossover design was used to assess the transient effect of five air pollutants (carbon monoxide (CO), nitrogen dioxide (NO2), nitric oxide (NO), ozone (O3) and particulate matter with an aerodynamic diameter ≤2.5 (PM2.5)) on the risk of AMI hospitalization over the period 1999-2009. Subgroups were predefined to see if any susceptible group of individuals existed. A three-step procedure, including univariate analysis, multivariate analysis, and bootstrap model averaging, was used. The multivariate analysis was used in an effort to address adjustment uncertainty; whereas the bootstrap technique was used as a way to account for regression model uncertainty. There were 25,894 AMI hospital admissions during the 11-year period. Estimating health effects that are properly adjusted for all possible confounding factors and accounting for model uncertainty are important for making interpretations of air pollution-health effect associations. The most robust findings included: (1) only 1-day lag NO2 concentrations (6-, 12- or 24-hour average), but not those of CO, NO, O3 or PM2.5, were associated with an elevated risk of AMI hospitalization; (2) evidence was suggested for an effect of elevated risk of hospitalization for NSTEMI (Non-ST Segment Elevation Myocardial Infarction), but not for STEMI (ST segment elevation myocardial infarction); and (3) susceptible subgroups included elders (age ≥65) and elders with hypertension. As this was only an exploratory study there is a need to replicate these findings with other methodologies and datasets.

    Aisha Lofters

    Full Text Available CONTEXT: Substantive equity-focused policy changes in Ontario, Canada have yet to be realized and may be limited by a lack of widespread public support. An understanding of how the public attributes inequalities can be informative for developing widespread support. Therefore, the objectives of this study were to examine how Ontarians attribute income-related health inequalities. METHODS: We conducted a telephone survey of 2,006 Ontarians using random digit dialing. The survey included thirteen questions relevant to the theme of attributions of income-related health inequalities, with each statement linked to a known social determinant of health. The statements were further categorized depending on whether the statement was framed around blaming the poor for health inequalities, the plight of the poor as a cause of health inequalities, or the privilege of the rich as a cause of health inequalities. RESULTS: There was high agreement for statements that attributed inequalities to differences between the rich and the poor in terms of employment, social status, income and food security, and conversely, the least agreement for statements that attributed inequalities to differences in terms of early childhood development, social exclusion, the social gradient and personal health practices and coping skills. Mean agreement was lower for the two statements that suggested blame for income-related health inequalities lies with the poor (43.1% than for the three statements that attributed inequalities to the plight of the poor (58.3% or the eight statements that attributed inequalities to the privilege of the rich (58.7%. DISCUSSION: A majority of this sample of Ontarians were willing to attribute inequalities to the social determinants of health, and were willing to accept messages that framed inequalities around the privilege of the rich or the plight of the poor. These findings will inform education campaigns, campaigns aimed at increasing public support

    Full Text Available Abstract Background Patients newly-diagnosed with diabetes require self-management education to help them understand and manage the disease. The goals of the study were to determine the frequency of diabetes self-management education program utilization by newly-diagnosed patients, and to evaluate whether there were any demographic or clinical disparities in utilization. Methods Using population-level health care data, all 46,553 adults who were diagnosed with any type of non-gestational diabetes in Ontario, Canada between January and June 2006 were identified. They were linked with a diabetes self-management education program registry to identify those who attended within 6 months of diagnosis. The demographic and clinical characteristics of attendees and non-attendees were compared. Results A total of 9,568 (20.6% patients attended a diabetes self-management education program within 6 months of diagnosis. Younger age, increasing socioeconomic status, and the absence of mental health conditions or other medical comorbidity were associated with attendance. Patients living in rural areas, where access to physicians may be limited, were markedly more likely to attend. Recent immigrants were 40% less likely to attend self-management education programs than longer-term immigrants or nonimmigrants. Conclusion Only one in five newly-diagnosed diabetes patients attended a diabetes self-management education program. Demographic and clinical disparities in utilization persisted despite a publicly-funded health care system where patients could access these services without direct charges. Primary care providers and education programs must ensure that more newly-diagnosed diabetes patients receive self-management education, particularly those who are older, poorer, sicker, or recent immigrants.

    Parliament Hill consists of four historic gothic revival buildings, which form part of the Parliament Buildings National Historic Site of Canada in the National Capital of Ottawa. There are more than 2000 masonry sculptural elements throughout the four buildings. Three of the buildings are in the middle of multi-year rehabilitation projects. Extensive Heritage Documentation is being undertaken to support various activities and conservation teams throughout the interior and exterior of the buildings while also serving as a key posterity records. One of the significant heritage documentation projects is the 3D digitization of the 2000+ heritage character defining sculptural elements. The Heritage Conservation Directorate (HCD) of Public Works and Government Services Canada (PWGSC) was tasked by the Parliamentary Precinct Branch (PPB) of PWGSC to document these character defining elements. The sculptures vary in size from as small as 100mm in width to up to 2 meters in size. This project is in its third year and much has been learned and researched about the most appropriate and efficient means by which to document these elements. Although a methodology was in place to document the sculptures at the inception of the project, it has gone through several iterations in order to improve the gathered data, and in turn increase the efficiency, quality and speed of data acquisition. This paper will describe the evolution of the methodology, as well as the rationale for the alterations in technique. With over 600 of the approximate 2000 (heritage character defining) sculptural elements captured to date, the project is entering a critical phase where an efficient and effective method for sharing and disseminating the information to a wide audience is being explored and evaluated. The end result is intended to allow the client (PPB) and the general public a way to look at and interactively manipulate the viewpoint of each digital model. This will provide a unique opportunity

    Current state of uranium industry in Canada has been considered. It is shown that in Canada, which is the major supplier of uranium, new methods of prospecting, mining and processing of uranium are developed and the old ones are improved. Owing to automation and mechanization a higher labour productivity in uranium ore mining is achieved. The uranium industry of Canada can satisfy the future demands in uranium but introduction of any new improvement will depend completely on the rate of nuclear power development.

    Canada`s climate change strategy has been the focus of extensive consultation processes whose objective is to provide recommendations to federal and provincial ministers by the end of 1999. They are also designed to study the impact, the cost and the benefits of implementation of the Kyoto Protocol and to develop immediate actions to provide early reductions in CO{sub 2} emissions. The development of long-term actions that will result in sustained greenhouse gas (GHG) reductions is also on the agenda. The role of the Electricity Sector Table is to determine the contribution of GHG emissions by power generation, transmission and distribution elements as well as by electricity and cogeneration industries. The contribution of GHG emissions by renewable energy is also being studied. One of the recommended early actions is that the federal government should include solution gas as a qualifying fuel in Class 43.1 of the Income Tax Act to provide incentives to produce electricity from waste solution gas in fossil fuel production. Natural Resources Canada predicts that GHG emissions from the electricity sector will have increased from 94 MT in 1990 to 146 MT by 2020. The current sources of power generation in Canada are as follows: hydroelectric (65 per cent), nuclear (15 per cent), coal (15 per cent), and other (5 per cent).

    Carrying out critical business functions without interruption requires a resilient and robust business continuity framework. By embedding an industry-standard incident management system within its business continuity structure, the Bank of Canada strengthened its response plan by enabling timely response to incidents while maintaining a strong focus on business continuity. A total programme approach, integrating the two disciplines, provided for enhanced recovery capabilities. While the value of an effective and efficient response organisation is clear, as demonstrated by emergency events around the world, incident response structures based on normal operating hierarchy can experience unique challenges. The internationally-recognised Incident Command System (ICS) model addresses these issues and reflects the five primary incident management functions, each contributing to the overall strength and effectiveness of the response organisation. The paper focuses on the Bank of Canada's successful implementation of the ICS model as its incident management and continuity of operations programmes evolved to reflect current best practices.

    Full Text Available Introduction: Awareness and knowledge of treatment as prevention (TasP was assessed among HIV-positive and HIV-negative gay, bisexual and other men who have sex with men (GBMSM in Vancouver, Canada. Methods: Baseline cross-sectional survey data were analyzed for GBMSM enrolled, via respondent-driven sampling (RDS, in the Momentum Health Study. TasP awareness was defined as ever versus never heard of the term “TasP.” Multivariable logistic regression identified covariates of TasP awareness. Among those aware of TasP, men's level of knowledge of TasP was explored through an examination of self-perceived knowledge levels, risk perceptions and short-answer definitions of TasP which were coded as “complete” if three TasP-related components were identified (i.e. HIV treatment, viral suppression and prevention of transmission. Information source was also assessed. Analyses were stratified by HIV status and RDS adjusted. Results: Of 719 participants, 23% were HIV-positive, 68% Caucasian and median age was 33 (Interquartile range (IQR 26,47. Overall, 46% heard of TasP with differences by HIV status [69% HIV-positive vs. 41% HIV-negative GBMSM (p<0.0001]. In adjusted models: HIV-positive GBMSM were more likely to have heard of TasP if they were Canadian born, unemployed, not using party drugs and had higher CD4 counts; HIV-negative GBMSM were more likely to have heard of TasP if they were Caucasian (vs. Aboriginal, students, had higher education, a regular partner and multiple sexual partners. Among those aware of TasP 91% of HIV-positive and 69% of HIV-negative GBMSM (p<0.0001 felt they knew “a lot” or “a bit in general” about TasP; 64 and 41% (p=0.002 felt HIV treatment made the risk of transmission “a lot lower”; and 21 and 13% (p<0.0001 demonstrated “complete” TasP definitions. The leading information source was doctors (44% for HIV-positive GBMSM and community agencies (38% for HIV-negative GBMSM, followed by gay media for

    2009-01-01

    Full Text Available AbstractSome analysts lean toward comparative analyses of population aging, then draw potential policy implications. Others lean in the direction of attention to differences in policy regimes and then consider implications of population aging. Key differences among advanced societies may not emanate from demographic aging but from differences in how markets, states, and families work to redistribute societal benefits. In this paper, three countries with contrasting configurations of markets, states, and families, and at different stages of demographic aging, are compared and contrasted: Canada, Japan, and Korea. The paper has three objectives: 1to outline key changes in population, family, and work in the three countries; 2 to consider how knowledge about these changes, their dynamics and interrelationships, is framed with respect to policy options; and 3 to compare Canada, Japan, and Korea in terms of the framing of policy challenges related to demographic aging. It is found that Canada is joining the longstanding pattern of Japan and Korea of late home-leaving by youth, meaning less effective time in the paid labour force. Little deep connection exists between population aging andeconomic productivity or labour force shortages. Differential labour market participation of women mediates the effects of population aging.RésuméIl y a des analystes qui ont un penchant pour les analyses comparatives du vieillissement despopulations, puis en déduisent les implications possibles sur les politiques.

    2011-11-01

    Full Text Available BACKGROUND: HIV infection rates are increasing among marginalized women in Ontario, Canada. HIV-related stigma, a principal factor contributing to the global HIV epidemic, interacts with structural inequities such as racism, sexism, and homophobia. The study objective was to explore experiences of stigma and coping strategies among HIV-positive women in Ontario, Canada. METHODS AND FINDINGS: We conducted a community-based qualitative investigation using focus groups to understand experiences of stigma and discrimination and coping methods among HIV-positive women from marginalized communities. We conducted 15 focus groups with HIV-positive women in five cities across Ontario, Canada. Data were analyzed using thematic analysis to enhance understanding of the lived experiences of diverse HIV-positive women. Focus group participants (n = 104; mean age = 38 years; 69% ethnic minority; 23% lesbian/bisexual; 22% transgender described stigma/discrimination and coping across micro (intra/interpersonal, meso (social/community, and macro (organizational/political realms. Participants across focus groups attributed experiences of stigma and discrimination to: HIV-related stigma, sexism and gender discrimination, racism, homophobia and transphobia, and involvement in sex work. Coping strategies included resilience (micro, social networks and support groups (meso, and challenging stigma (macro. CONCLUSIONS: HIV-positive women described interdependent and mutually constitutive relationships between marginalized social identities and inequities such as HIV-related stigma, sexism, racism, and homo/transphobia. These overlapping, multilevel forms of stigma and discrimination are representative of an intersectional model of stigma and discrimination. The present findings also suggest that micro, meso, and macro level factors simultaneously present barriers to health and well being--as well as opportunities for coping--in HIV-positive women's lives

    Urban expansion, particularly the movement of residential and commercial land use to sub-urban areas in metropolitan areas, has been considered as a significant signal of regional economic development. In 1970s, the economic centre of Canada moved from Montreal to Toronto. Since some previous research have been focused on the urbanization process in Greater Toronto Area (GTA), it is significant to conduct research in its counterpart. This study evaluates urban expansion process in Montréal census metropolitan area (CMA), Canada, between 1975 and 2015 using satellite images and socio-economic data. Spatial and temporal dynamic information of urbanization process was quantified using Landsat imagery, supervised classification algorithms and the post-classification change detection technique. Accuracy of the Landsat-derived land use classification map ranged from 80% to 97%. The results indicated that continuous growth of built-up areas in the CMA over the study period resulted in a decrease in the area of cultivated land and vegetation. The results showed that urban areas expanded 442 km2 both along major river systems and lakeshores, as well as expanded from urban centres to surrounded areas. The analysis revealed that urban expansion has been largely driven by population growth and economic development. Consequently, the urban expansion maps produced in this research can assist decision-makers to promote sustainable urban development, and forecast potential changes in urbanization growth patterns.

    Full Text Available Union formation and dissolution are among the main determinants explaining variations in fertility. Compared to the rest of Canada, Quebec’s marital histories are more complex and its prevalence of common-law unions much higher. The objective of this article is to examine the role of marital behaviours on fertility by comparing different indicators of fertility and conjugal life that were obtained through microsimulation. Parameters of the microsimulation model were estimated from hazard regressions performed on the marital and fertility histories collected in two retrospective longitudinal surveys: the Canadian General Social Survey (GSS 2001 and 2006. Results show that the more complex marital histories of Quebecers can explain more than one-quarter of their fertility differences with the rest of the country.

    Full Text Available Abstract Background Immunization information systems (IISs are electronic registries used to monitor individual vaccination status and assess vaccine coverage. IISs are currently not widely used across Canada, where health jurisdictions employ a range of approaches to capture influenza immunization information. Conducted in advance of the 2009 H1N1 vaccination campaign, the objectives of this study were to understand the perceived value of individual-level data and IISs for influenza control, identify ideal system functions, and explore barriers to implementation. Methods In July and August 2009, semi-structured interviews were conducted with key informants engaged in vaccine delivery and/or pandemic planning at regional, provincial/territorial and federal levels across Canada. Key informants were recruited using a combination of convenience and snowball sampling methodologies. Qualitative analysis was used to extract themes from interview content. Results Patient management, assessment of vaccine coverage, and evaluation of safety and effectiveness were identified as public health priorities that would be achieved in a more timely manner, and with greater accuracy, through the use of an IIS. Features described as ideal included system flexibility, rapid data entry, and universality. Financial and human resource constraints as well as coordination between immunization providers were expressed as barriers to implementation. Conclusions IISs were perceived as valuable by key informants for strengthening management capacity and improving evaluation of both seasonal and pandemic influenza vaccination campaigns. However, certain implementation restrictions may need to be overcome for these benefits to be achieved.

    Small-bodied fishes are more commonly being used in environmental effects monitoring (EEM) studies. There is a lack of understanding of the biological characteristics of many small-bodied species, which hinders study designs for monitoring studies. For example, 72% of fish population surveys in Canada's EEM program for pulp and paper mills that used small-bodied fishes were conducted outside of the reproductive period of the species. This resulted in an inadequate assessment of the EEM program's primary effect endpoint (reproduction) for these studies. The present study examined seasonal changes in liver size, gonad size, and condition in seven freshwater and estuarine small-bodied fishes in Atlantic Canada. These data were used to examine differences in reproductive strategies and patterns of energy storage among species. Female gonadal recrudescence in all seven species began primarily in the 2-month period in the spring before spawning. Male gonadal development was concurrent with females in five species; however, gonadal recrudescence began in the fall in male three-spined stickleback (Gasterosteus aculeatus) and slimy sculpin (Cottus cognatus). The spawning period for each species was estimated from the decline in relative ovary size after its seasonal maximum value in spring. The duration of the spawning period reflected the reproductive strategy (single vs multiple spawning) of the species. Optimal sampling periods to assess reproductive impacts in each species were determined based on seasonal changes in ovary size and were identified to be during the prespawning period when gonads are developing and variability in relative gonad size is at a minimum.

    Full Text Available Abstract Background Identifying risk factors for Salmonella Enteritidis (SE infections in Ontario will assist public health authorities to design effective control and prevention programs to reduce the burden of SE infections. Our research objective was to identify risk factors for acquiring SE infections with various phage types (PT in Ontario, Canada. We hypothesized that certain PTs (e.g., PT8 and PT13a have specific risk factors for infection. Methods Our study included endemic SE cases with various PTs whose isolates were submitted to the Public Health Laboratory-Toronto from January 20th to August 12th, 2011. Cases were interviewed using a standardized questionnaire that included questions pertaining to demographics, travel history, clinical symptoms, contact with animals, and food exposures. A multinomial logistic regression method using the Generalized Linear Latent and Mixed Model procedure and a case-case study design were used to identify risk factors for acquiring SE infections with various PTs in Ontario, Canada. In the multinomial logistic regression model, the outcome variable had three categories representing human infections caused by SE PT8, PT13a, and all other SE PTs (i.e., non-PT8/non-PT13a as a referent category to which the other two categories were compared. Results In the multivariable model, SE PT8 was positively associated with contact with dogs (OR=2.17, 95% CI 1.01-4.68 and negatively associated with pepper consumption (OR=0.35, 95% CI 0.13-0.94, after adjusting for age categories and gender, and using exposure periods and health regions as random effects to account for clustering. Conclusions Our study findings offer interesting hypotheses about the role of phage type-specific risk factors. Multinomial logistic regression analysis and the case-case study approach are novel methodologies to evaluate associations among SE infections with different PTs and various risk factors.

    Full Text Available Heat flow of the sedimentary succession of the Eastern Canada Sedimentary Basins varies from 40 mW/m2 close to the exposed shield in the north to high 60–70 mW/m2 in the southwest–northeast St. Lawrence corridor. As high fluid flow rates are required for a successful geothermal application, the most important targets are deep existing permeable aquifers rather than hard rock, which would need to be fracked. Unfortunately, the ten most populated Québec urban centers are in the areas where the Grenville (Canadian Shield is exposed or at shallow depths with sedimentary cover where temperatures are 30 °C or less. The city of Drummondville will be the exception, as the basement deepens sharply southwest, and higher temperatures reaching >120 °C are expected in the deep Cambrian sedimentary aquifers near a 4–5-km depth. Deep under the area where such sediments could be occurring under Appalachian nappes, temperatures significantly higher than 140 °C are predicted. In parts of the deep basin, temperatures as high as 80 °C–120 °C exist at depths of 3–4 km, mainly southeast of the major geological boundary: the Logan line. There is a large amount of heat resource at such depths to be considered in this area for district heating.

    Companion animals closely share their domestic environment with people and have the potential to, act as sources of zoonotic diseases. They also have the potential to be sentinels of infectious and noninfectious, diseases. With the exception of rabies, there has been minimal ongoing surveillance of, companion animals in Canada. We developed customized data extraction software, the University of, Calgary Data Extraction Program (UCDEP), to automatically extract and warehouse the electronic, medical records (EMR) from participating private veterinary practices to make them available for, disease surveillance and knowledge creation for evidence-based practice. It was not possible to build, generic data extraction software; the UCDEP required customization to meet the specific software, capabilities of the veterinary practices. The UCDEP, tailored to the participating veterinary practices', management software, was capable of extracting data from the EMR with greater than 99%, completeness and accuracy. The experiences of the people developing and using the UCDEP and the, quality of the extracted data were evaluated. The electronic medical record data stored in the data, warehouse may be a valuable resource for surveillance and evidence-based medical research.

    We analyzed changes in distribution and abundance of forest birds due to different types of recreational activity in the Madrid province (Guadarrama Range, Central Spain). Census plots were distributed in forest interiors (undisturbed sites), along forest trails (transiently disturbed hiking tracks), and in recreational areas (long-lasting disturbed picnic sites). Parameters describing the overall bird community (I.e.total bird abundance, species richness and diversity), groups of species (I.e. Abundance of corvids and nesting or foraging guilds) and individual species abundances were compared. Forest sites with any type of human presence (trails and picnic sites pooled) had higher overall abundances and species richness per sampling plot than undisturbed forest interiors. Furthermore, fourteen species were significantly more abundant in disturbed sites than in forest interiors, while the converse was true only for five species. Anthropogenic sites did not affect forest specialists. Canopy-nesters, trunk and ground-foragers, and corvids were more abundant at recreational sites than in undisturbed forests, while the converse pattern was observed for ground-nesters. These patterns were more distinct in deciduous than in coniferous forest tracts. The positive effects of recreational sites were mostly associated with picnic sites, since forest trails were mostly indistinguishable from undisturbed forest interiors in terms of bird community patterns. Several habitat characteristics of disturbed sites can explain some of these differences: increased maturity of the tree layer, less dense subcanopy vegetation, higher abundance of holes and crevices, and greater predictability and availability of human food waste in picnic areas. So, contrary to expectations, we conclude that these types of nonconsumptive recreation do not decrease habitat suitability for most birds, although it might decrease suitability for ground-nesting birds.%我们对西班牙马德里森林深处(

    We discuss ethical challenges and opportunities experienced by peer research assistants (PRAs) in a multi-method HIV community-based research study in Ontario, Canada. We review lessons learned and best practices based on our experience conducting a qualitative investigation of research priorities with diverse women living with HIV (WLWH) and implementation of a cross-sectional survey with African, Caribbean, and Black WLWH. While some opportunities were similar across research phases for PRAs (e.g., skill building), distinct challenges emerged in qualitative and quantitative phases. For example, our training did not adequately prepare PRAs with focus group facilitation skills; at times, survey implementation became counseling sessions. Researchers should assess how best to support PRAs as part of multi-method research processes.

    A population of approximately 650 beluga (Delphinapterus leucas) inhabits a short segment of the St. Lawrence estuary (SLE). Over 17 years (1983-1999), we have examined 129 (or 49%) of 263 SLE beluga carcasses reported stranded. The major primary causes of death were respiratory and gastrointestinal infections with metazoan parasites (22%), cancer (18%), and bacterial, viral, and protozoan infections (17%). We observed cancer in 27% of examined adult animals found dead, a percentage similar to that found in humans. The estimated annual rate (AR) of all cancer types (163/100,000 animals) is much higher than that reported for any other population of cetacean and is similar to that of humans and to that of hospitalized cats and cattle. The AR of cancer of the proximal intestine, a minimum figure of 63 per 100,000 animals, is much higher than that observed in domestic animals and humans, except in sheep in certain parts of the world, where environmental contaminants are believed to be involved in the etiology of this condition. SLE beluga and their environment are contaminated by polycyclic aromatic hydrocarbons (PAHs) produced by the local aluminum smelters. The human population living in proximity of the SLE beluga habitat is affected by rates of cancer higher than those found in people in the rest of Québec and Canada, and some of these cancers have been epidemiologically related to PAHs. Considered with the above observations, the exposure of SLE beluga to PAHs and their contamination by these compounds are consistent with the hypothesis that PAHs are involved in the etiology of cancer in these animals.

    The Canadian National Committee picked five of the ten IYPE themes for emphasis in Canada - Water, Hazards, Energy, Resources and Environment. They are summarized in the acronym WHERE - WHERE on Earth, WHERE in Canada. Our committee raised funds from industry, with some generous support from The Geological Survey of Canada. Funds were used for publishing “Four Billion Years and Counting”, a book on Canadian geology designed for the general public. It will be useful to educators who can download many of the illustrations and images for classroom support. Recognizing the looming shortage of Geoscientists, we designed a new careers website to help attract young people to the Earth sciences. It can be seen on our website, www.EarthsciencesCanada.com. The website will be updated regularly. The WHERE Challenge was a national contest for children aged 10 to 14. They were asked to select an object, often something from their household, identify at least one non-renewable resource used to make the object, and submit an entry describing the object, the resources within it, and WHERE they came from. We received entries from more than 1000 students Some of the winning entries are posted on our website. We developed a partnership with Parks Canada called Egoists, which is a series of pamphlets on iconic views within the parks explaining the Earth science behind the views. We also supported the celebration of the 100th anniversary of the discovery of the Burgess Shale by providing funding for the publication of a field guide. At the end of the year all programs will transfer to the Canadian Federation of Earth Sciences. The WHERE Challenge will be repeated in 2010. It, plus our book and careers website will continue our outreach activities.

    Magnetic anomaly patterns on opposite sides of the mapped Tintina fault in eastern Alaska and western Canada show an apparent offset of about 490 kilometers (km), probably of Eocene age. This estimate is compared with previous geologically based estimates of 400 to 430 km and paleomagnetically based estimates of more than 1,100 km. The apparent geophysical alignments have geologic implications that deserve further study.

    Douglas Shale

    2002-01-01

    Full Text Available Canada's postsecondary institutions are becoming increasingly involved with technology enhanced learning, generally under the rubric of distance education. Growth and activity in distance education stems from rapid developments in communication and information technologies such as videoconferencing and the Internet. This case study focuses on the use of new technologies, primarily within the context of higher education institutions operating in Canada's English speaking provinces. Capitalising on the interactive capabilities of "new" learning technologies, some distance education providers are starting to behave more like conventional educational institutions in terms of forming study groups and student cohorts. Conversely, new telecommunications technologies are having a reverse impact on traditional classroom settings, and as a result conventional universities are beginning to establish administrative structures reflective of those used by distance education providers. When viewed in tandem, these trends reflect growing convergence between conventional and distance learning modes, leading to the hybridisation of higher education in Canada.

  17. Transboundary study of the Milk River aquifer (Canada, USA): geological, conceptual and numerical models for the sound management of the regional groundwater resources

    2016-04-01

    The Milk River transboundary aquifer straddles southern Alberta (Canada) and northern Montana (United States), a semi-arid and water-short region. The extensive use of this regional sandstone aquifer over the 20th century has led to a major drop in water levels locally, and concerns about the durability of the resources have been raised since the mid-1950. Even though the Milk River Aquifer (MRA) has been studied for decades, most of the previous studies were limited by the international border, preventing a sound understanding of the aquifer dynamics. Yet, a complete portrait of the aquifer is required for proper management of this shared resource. The transboundary study of the MRA aims to overcome transboundary limitations by providing a comprehensive characterization of the groundwater resource at the aquifer scale, following a three-stage approach: 1) The development of a 3D unified geological model of the MRA (50,000 km2). The stratigraphic framework on both sides of the border was harmonized and various sources of geological data were unified to build the transboundary geological model. The delineation of the aquifer and the geometry and thicknesses of the geological units were defined continuously across the border. 2) Elaboration of a conceptual hydrogeological model by linking hydrogeological and geochemical data with the 3D unified geological model. This stage is based on a thorough literature review and focused complementary field work on both sides of the border. The conceptual model includes the determination of the groundwater flow pattern, the spatial distribution of hydraulic properties, a groundwater budget and the definition of the groundwater types. Isotopes (3H, 14C, 36Cl) were used to delineate the recharge area as well as the active and low-flow areas. 3) The building of a 3D numerical groundwater flow model of the MRA (26,000 km2). This model is a transposition of the geological and hydrogeological conceptual models. A pre

    There is relatively little known about the demand for allograft tissues in Canada. The Canadian Council for Donation and Transplantation (CCDT) is a national advisory body that undertook a comprehensive "market survey" to estimate surgical demand for human allograft tissues in Canada. The report "Demand for Human Allograft Tissue in Canada" reflects survey results sent to 5 prominent User Groups. User Groups were identified as orthopaedic surgeons; neurosurgeons; corneal transplant surgeons; plastic surgeons, specifically those at Canadian Burn Units; and cardiac surgeons (adult and paediatric surgery). The demand for allograft grafts was determined and then extrapolated across the total User Group and then increases in allograft tissue use over the next 1-2 years across User Groups were predicted. The overall response rate for the survey was 21.4%. It varied from a low of 19.6% for the orthopaedic survey to a high of 40.5% for the corneal survey. The estimated current demand for allograft tissue in Canada ranges from a low of 34,442 grafts per year to a high of 62,098 grafts per year. The predicted increase in use of allograft tissue over the next 1-2 year period would suggest that annual demand could rise to somewhere in the range of 42,589-72,210 grafts. The highest rated preferences (98% and 94%) were for accredited and Canadian tissue banks, respectively. This study represents a key step in addressing the paucity of information concerning the demand for allograft tissue in Canada.

    2007-12-01

    The origins of neurosurgical services in Atlantic Canada are tied to the individual efforts of William D. Stevenson. Born in Hamilton, Ontario, Stevenson completed his senior matriculation in Dunnville, Ontario, before studying medicine at the University of Toronto. He completed the Gallie surgical course in Toronto and then spent 1 year training with Edward Archibald at McGill University. After working for 2 years with the Canadian Mobile Neurosurgical Unit in Europe during the Second World War, Stevenson undertook formal neurosurgical training with Kenneth G. McKenzie, Canada's first neurosurgeon. Stevenson was thereafter recruited to Halifax to start the neurosurgical service at the Victoria General Hospital in January 1948, and he remained head of the division for the next 26 years. His pioneering work laid the foundations for the establishment of a major academic neurosurgical service at Dalhousie University and was crucial for the establishment of neurosurgery in Atlantic Canada. After his retirement, Stevenson moved back to Ontario and began his second career, transferring his passion for neurosurgery to oil painting. His legacy to neurosurgery in Atlantic Canada will be remembered in perpetuity with the annual Neurosurgery Resident Research Award at Dalhousie University, established and named in his honour. This paper focuses on Stevenson's life and work in neurosurgery as Atlantic Canada's first neurosurgeon.

    This was an international study of women's health issues, based on an Official Study Tour in Southeast Asia (the Philippines, Thailand, Malaysia, Hong Kong, and Singapore) and Canada. The objectives of the study were to identify and compare current gaps in surveillance, research, and programs and policies, and to predict trends of women's health issues in developing countries based on the experience of developed countries. Key informant interviews (senior government officials, university researchers, and local experts), self-administered questionnaires, courtesy calls, and literature searches were used to collect data. The participating countries identified women's health as an important issue, especially for reproductive health (developing countries) and senior's health (developed countries). Cancer, lack of physical activity, high blood pressure, diabetes, poverty, social support, caring role for family, and informing, educating, and empowering people about women's health issues were the main concerns. Based on this study, 17 recommendations were made on surveillance, research, and programs and policies. A number of forthcoming changes in women''s health patterns in developing countries were also predicted.

    Transnational commercial surrogacy represents a form of medical tourism undertaken by intended parents who seek to hire women in other countries, increasingly often in the global South, as surrogates. While much of the scholarly literature focuses on the conditions of surrogacy within host countries, such as India, there has been limited analysis of transnational surrogacy focused upon origin countries. In this article, I build upon the scholarship that explores the impact of host country structures on transnational surrogacy, with special attention to the significance of Canadian citizenship policy through analysis of legislation and policy vis-à-vis transnational commercial surrogacy. The Canadian case demonstrates clear contradictions between the legislation and policy that is enacted domestically to prohibit commercial surrogacy within Canada and legislation and policy that implicitly sanctions commercial surrogacy through the straightforward provision of citizenship for children born of such arrangements abroad. The ethical underpinnings of Canada's domestic prohibition of commercial surrogacy, which is presumed to exploit women and children and to impede gender equality, are violated in Canada's bureaucratic willingness to accept children born of transnational commercial surrogacy as citizens. Thus, the ethical discourses apply only to Canadian citizens within Canadian geography. The failure of the Canadian government to hold Canadian citizens who participate in transnational commercial surrogacy to the normative imperatives that prohibit the practice within the country, or to undertake a more nuanced, and necessarily controversial, discussion of commercial surrogacy reinforces transnational disparities in terms of whose bodies may be commodified as a measure of gendered inequality.

    OECD's comprehensive 2004 report on Canada's environmental policies and programmes systematically examines policy related to air, water, and nature/biodiversity as well as the interface between environmental policy and economic policy, social policy, and specific sectors. It finds that while Canada has made satisfactory progress since 1985, there are still significant challenges, and the report makes specific recommendations for more use of economic instruments and use of the polluter and user pays principles, rationalising water governance, strengthening nature protection, reducing energy intensity, implementing climate change policies, reviewing environmentally related taxes, and implementing marine and aid commitments. Coal provides about 20% of Canada's electric power. Most direct subsidisation of the fossil fuel supply industries (upstream oil, gas and coal) has been reduced. The report recommends subsidies to the mining industry for exploration should also be phased out. Recent measurements indicate emissions of mercury are increasing, mainly due to long-range transboundary air pollution from coal-burning plants. 42 figs., 24 tabs.

    Numerous studies have examined the association of air pollution with preterm birth and birth weight outcomes. Traffic-related air pollution has also increasingly been identified as an important contributor to adverse health effects of air pollution. We employed a national nitrogen dioxide (NO2) exposure model to examine the association between NO2 and pregnancy outcomes in Canada between 1999 and 2008. National models for NO2 (and particulate matter of median aerodynamic diameter road traffic sources. Generalized estimating equations were used to examine associations with preterm birth, term low birth weight (LBW), small for gestational age (SGA) and term birth weight, adjusting for covariates including infant sex, gestational age, maternal age and marital status, parity, urban/rural place of residence, maternal place of birth, season, year of birth and neighbourhood socioeconomic status and per cent visible minority. Associations were reduced considerably after adjustment for individual covariates and neighbourhood per cent visible minority, but remained significant for SGA (odds ratio 1.04, 95%CI 1.02-1.06 per 20ppb NO2) and term birth weight (16.2g reduction, 95% CI 13.6-18.8g per 20ppb NO2). Associations with NO2 were of greater magnitude in a sensitivity analysis using monthly monitoring data, and among births to mothers born in Canada, and in neighbourhoods with higher incomes and a lower proportion of visible minorities. In two pollutant models, associations with NO2 were less sensitive to adjustment for PM2.5 than vice versa, and there was consistent evidence of a dose-response relationship for NO2 but not PM2.5. In this study of approximately 2.5 million Canadian births between 1999 and 2008, we found significant associations of NO2 with SGA and term birth weight which remained significant after adjustment for PM2.5, suggesting that traffic may be a particularly important source with respect to the role of air pollution as a risk factor for adverse

    North American bison producers have been attempting to control and prevent Mycoplasma bovis-associated disease without the benefit of bison-specific knowledge. The objective of this study was to determine the clinical presentation of disease associated with M. bovis infection in western Canadian farmed bison, and to identify herd-level risk factors for M. bovis-associated disease. Bison producers (n=49) from western Canada (Manitoba, Saskatchewan, Alberta, and British Columbia) were selected for a 1:2 case-control study. Data were collected by an in-person interview using a questionnaire regarding clinical presentations of outbreaks and herd-level management factors. Risk factors associated with M. bovis outbreaks were identified using multivariable logistic regression analysis. All 17 case herds had a laboratory-confirmed diagnosis of M. bovis infection within the last 5 years. In 11 (65%) of the 17 case herds, disease associated with M. bovis infection recurred in subsequent years. Overall, 88% of case herds had recently introduced bison that later developed clinical signs associated with M. bovis infection. Within a bison operation, a median of 8% (Inter Quartile Range [IQR]: 3-11%) developed clinical signs: lameness, reluctance to move, swollen joints, difficulty breathing, coughing, sluggishness, and loss of body condition. Also, calving percentage the year after the first M. bovis outbreak was lower than calving percentage the year before the outbreak. Herd-level mortality risk during the first M. bovis outbreak in case herds ranged from 0.5 to 50% (median 5%, IQR: 3-10%) and the median case fatality risk was 100%. Case herds were more likely than control herds to have a feedlot unit (OR=7), to receive regular visits from rental trailers or trailers from other farms (OR=15), to annually vaccinate bison (OR=7), and to lose at least one bison due to fatal respiratory disease in the previous year (OR=9). These findings will aid development of evidence

    Full Text Available Background. Bone strength in Inuit people appears lower than that of non-Aboriginals. Inuit are exposed to persistent organic pollutants including dioxin-like compounds (DLCs through their traditional diet that comprises predatory fish and marine mammal fat. Results from experimental and population studies suggest that some DLCs can alter bone metabolism and increase bone fragility. Objective. This cross-sectional descriptive study was conducted to examine the relationship between the stiffness index (SI and plasma concentrations of total DLCs or specific dioxin-like polychlorinated biphenyls (DL-PCBs in Inuit women of Nunavik (Northern Quebec, Canada. Methods. SI was determined by ultrasonography at the right calcaneus of 194 Inuit women aged 35–72 years who participated to Qanuippitaa? How Are We? Nunavik Inuit Health Survey in 2004. Plasma total DLC levels were quantified by measuring the aryl hydrocarbon receptor–mediated transcriptional activity elicited by plasma sample extracts in a cell-based reporter gene assay. Plasma concentrations of DL-PCBs nos. 105, 118, 156, 157, 167 and 189 were measured by gas chromatography–mass spectrometry. We used multiple linear regression analyses to investigate relations between total DLCs or specific DL-PCBs and SI, taking into consideration several potential confounders. Results. Neither total plasma DLCs nor specific DL-PCBs were associated with SI after adjustment for several confounders and covariates. Conclusion. Our results do not support a relation between exposure to DLCs and bone strength measured by ultrasonography in Inuit women of Nunavik.

    Full Text Available Abstract Background Research regarding the decision to adopt and implement technological innovations in radiation oncology is lacking. This is particularly problematic since these technologies are often complex and rapidly evolving, requiring ongoing revisiting of decisions regarding which technologies are the most appropriate to support. Variations in adoption and implementation decisions for new radiation technologies across cancer centres can impact patients' access to appropriate and innovative forms of radiation therapy. This study examines the key steps in the process of adopting and implementing intensity modulated radiation therapy (IMRT in publicly funded cancer centres and identifies facilitating or impeding factors. Methods A multiple case study design, utilizing document analysis and key informant interviews was employed. Four cancer centres in Ontario, Canada were selected and interviews were conducted with radiation oncologists, medical physicists, radiation therapists, and senior administrative leaders. Results Eighteen key informants were interviewed. Overall, three centres made fair to excellent progress in the implementation of IMRT, while one centre achieved only limited implementation as of 2009. Key factors that influenced the extent of IMRT implementation were categorized as: 1 leadership, 2 training, expertise and standardization, 3 collaboration, 4 resources, and 5 resistance to change. Conclusion A framework for the adoption and implementation of complex and evolving technologies is presented. It identifies the key factors that should be addressed by decision-makers at specific stages of the adoption/implementation process.

    Full Text Available Introduction: Rural residents of the United States (US and Canada face problems in accessing healthcare. International medical graduates (IMGs play an important role in delivering rural healthcare. IMGs from Caribbean medical schools have the highest proportion of physicians in primary care.  Xavier University School of Medicines admits students from the US, Canada and other countries to the undergraduate medical (MD course and also offers a premedical program. The present study was conducted to obtain student perception about working in rural US/Canada after graduation.   Methods: The study was conducted among premedical and preclinical undergraduate medical (MD students during October 2014. The questionnaire used was modified from a previous study. Semester of study, gender, nationality, place of residence and occupation of parents were noted. Information about whether students plan to work in rural US/Canada after graduation, possible reasons why doctors are reluctant to work in rural areas, how the government can encourage rural practice, possible problems respondents anticipate while working in rural areas were among the topics studied. Results: Ninety nine of the 108 students (91.7% participated. Forty respondents were in favor of working in rural US/Canada after graduation. Respondents mentioned good housing, regular electricity, water supply, telecommunication facilities, and schools for education of children as important conditions to be fulfilled. The government should provide higher salaries to rural doctors, help with loan repayment, and provide opportunities for professional growth.  Potential problems mentioned were difficulty in being accepted by the rural community, problems in convincing patients to follow medical advice, lack of exposure to rural life among the respondents, and cultural issues. Conclusions: About 40% of respondents would consider working in rural US/Canada. Conditions required to be fulfilled have been

    This study used a contingent choice method to determine the economic value of improving various ecosystem services (ESs) of the Blue Network of Greater Montreal (Quebec, Canada). Three real projects were used and the evaluation focused on six ESs that are related to freshwater aquatic ecosystems: biodiversity, water quality, carbon sequestration, recreational activities, landscape aesthetics and education services. We also estimated the value associated with the superficies of restored sites. We calculated the monetary value that a household would be willing to pay for each additional qualitative or quantitative unit of different ESs, and these marginal values range from $0.11 to $15.39 per household per unit. Thus, under certain assumptions, we determined the monetary values that all Quebec households would allocate to improve each ES in Greater Montreal by one unit. The most valued ES was water quality ($13.5 million), followed by education services ($10.7 million), recreational activities ($8.9 million), landscape aesthetics ($4.1 million), biodiversity ($1.2 million), and carbon sequestration ($0.1 million). Our results ascribe monetary values to improved (or degraded) aquatic ecosystems in the Blue Network of Greater Montreal, but can also enhance economic analyses of various aquatic ecosystem restoration and management projects.

    Full Text Available Abstract Background Recent studies have observed positive associations between outdoor air pollution and emergency department (ED visits for asthma. However, few have examined the possible confounding influence of aeroallergens, or reported findings among very young children. Methods A time stratified case-crossover design was used to examine 57,912 ED asthma visits among individuals two years of age and older in the census metropolitan area of Edmonton, Canada between April 1, 1992 and March 31, 2002. Daily air pollution levels for the entire region were estimated from three fixed-site monitoring stations. Similarly, daily levels of aeroallergens were estimated using rotational impaction sampling methods for the period between 1996 and 2002. Odds ratios and their corresponding 95% confidence intervals were estimated using conditional logistic regression with adjustment for temperature, relative humidity and seasonal epidemics of viral related respiratory disease. Results Positive associations for asthma visits with outdoor air pollution levels were observed between April and September, but were absent during the remainder of the year. Effects were strongest among young children. Namely, an increase in the interquartile range of the 5-day average for NO2 and CO levels between April and September was associated with a 50% and 48% increase, respectively, in the number of ED visits among children 2 – 4 years of age (p Conclusion Our findings, taken together, suggest that exposure to ambient levels of air pollution is an important determinant of ED visits for asthma, particularly among young children and the elderly.

    A population-based case-control study of cancer and occupation was carried out in Montréal, Canada. Between 1979 and 1986, 449 pathologically confirmed cases of prostate cancer were interviewed, as well as 1,550 cancer controls and 533 population controls. Job histories were evaluated by a team of chemist/hygienists using a checklist of 294 workplace chemicals. After preliminary evaluation, 17 occupations, 11 industries, and 27 substances were selected for multivariate logistic regression analyses to estimate the odds ratio between each occupational circumstance and prostate cancer with control for potential confounders. There was moderate support for risk due to the following occupations: electrical power workers, water transport workers, aircraft fabricators, metal product fabricators, structural metal erectors, and railway transport workers. The following substances exhibited moderately strong associations: metallic dust, liquid fuel combustion products, lubricating oils and greases, and polyaromatic hydrocarbons from coal. While the population attributable risk, estimated at between 12% and 21% for these occupational exposures, may be an overestimate due to our method of analysis, even if the true attributable fraction were in the range of 5-10%, this represents an important public health issue.

    Full Text Available Abstract Background Métis are descendants of early 17th century relationships between North American Indians and Europeans. This study's objectives were: (1 to compare the health status of the Métis people to all other residents of Manitoba, Canada; and (2 to analyze factors in predicting the likelihood of diabetes and related lower limb amputation. Methods Using de-identified administrative databases plus the Métis Population Database housed at the Manitoba Centre for Health Policy, age/sex-adjusted rates of mortality and disease were calculated for Métis (n = 73,016 and all other Manitobans (n = 1,104,672. Diseases included: hypertension, arthritis, diabetes, ischemic heart disease (age 19+; osteoporosis (age 50+; acute myocardial infarction (AMI and stroke (age 40+; total respiratory morbidity (TRM, all ages. Using logistic regression, predictors of diabetes (2004/05-2006/07 and diabetes-related lower-limb amputations (2002/03-2006/07 were analyzed. Results Disease rates were higher for Métis compared to all others: premature mortality before age 75 (4.0 vs. 3.3 per 1000, p Conclusion Despite universal healthcare, Métis' illness and mortality rates are mostly higher. Although elevated diabetes risk persists for the Métis even after adjusting for sociodemographic, healthcare and comorbidity variables, the risk of amputation for Métis appears more related to healthcare access rather than ethnicity.

    The Deepwater Horizon oil spill caused the death of a large number of seabirds in the Gulf of Mexico in 2010. However, the long term consequences of oil exposure on migratory birds overwintering in this area have received limited attention. The present study aimed to investigate the impact of oil contamination (e.g., polycyclic aromatic hydrocarbons (PAHs)) on the circulating status of prolactin and corticosterone, two hormones that influence reproductive success in birds, in Northern gannets (Morus bassanus) breeding on Bonaventure Island, Eastern Canada. Using light-based geolocators, it was found that 23.5% of Northern gannets from Bonaventure Island overwintered in the Gulf of Mexico in 2010-2011; the remainder of this population overwintered along the Atlantic Coast of the United States. PAH concentrations (eight compounds) in gannet blood cells were all found to be under the method limits of quantification, which could be the result of the ability of seabirds to metabolize these compounds and the time elapsed between oil exposure and blood sampling. Corticosterone and prolactin levels as well as body mass did not differ between the two major birds' wintering sites. Moreover, levels of both these hormones did not vary from early to late incubation period. Present results suggest that if Bonaventure Island-breeding Northern gannets had been exposed to oil in the Gulf of Mexico in the aftermath of this historical spill, this exposure could not be associated with changes in hormonal status and body mass in breeding individuals.

    Full Text Available The orchard crop pollinator Osmia lignaria (Hymenoptera: Megachilidae was evaluated for apple pollination in the Annapolis Valley, Nova Scotia, Canada during 2000-2001. Resulting pollination levels (measured as pollen grains on floral stigmas, percent fruit set, mature fruit weight and seed yield were evaluated against an attempted gradient of Osmia bee density. In addition, fruit quality was assessed using two symmetry indices, one based on fruit diameter, the second on fruit height. Pollination levels, percent fruit set and mature fruit quality were much higher than minimums required for adequate crop production, and all but pollination levels showed weak but significant decreases at increased distance from the established nests, suggesting that even at low numbers these bees may have been making significant contributions to apple production. Fruit were typically of better quality in areas of the orchard adjacent to Osmia nests, having fewer empty carpels and greater symmetry; fruit quality (i.e., symmetry is typically most reduced when two or more adjacent carpels are empty. Empty carpels reduce growth in fruit height rather than diameter, suggesting that symmetry indices using fruit diameter are not sensitive enough to evaluate fruit quality. Evidencing this, fruit without mature seeds observed in this study showed high symmetry based on diameter, but were greatly asymmetric with respect to fruit height. Further discussion on Osmia bees as apple pollinators and on methods of evaluating apple fruit quality with respect to seed distribution within the apple fruit are provided.

    Full Text Available Background. A convenient, private, and accessible HIV self-testing strategy stands to complement facility-based conventional testing. Over-the-counter oral HIV self-tests are approved and available in the United States, but not yet in Canada. Canadian data on self-testing is nonexistent. We investigated the feasibility of offering an unsupervised self-testing strategy to Canadian students. Methods. Between September 2011 and May 2012, we recruited 145 students from a student health clinic of a large Canadian university. Feasibility of operationalization (i.e., self-test conduct, acceptability, convenience, and willingness to pay was evaluated. Self-test conduct was computed with agreement between the self-test performed by the student and the test repeated by a healthcare professional. Other metrics were measured on a survey. Results. Participants were young (median age: 22 years, unmarried (97%, and 47% were out of province or international students. Approximately 52% self-reported a history of unprotected casual sex and sex with multiple partners. Self-test conduct agreement was high (100%, so were acceptability (81%, convenience (99%, and willingness to pay (74% for self-tests. Concerns included accuracy of self-tests and availability of expedited linkages. Conclusion. An unsupervised self-testing strategy was found to be feasible in Canadian students. Findings call for studies in at-risk populations to inform Canadian policy.

    Homogeneity of a peridotitic garnet inclusion in diamond demonstrating excess in Si concentration (i.e. presence of majorite component) was investigated by TEM using FIB prepared foils. The host diamond is a low-nitrogen brown stone, which can be related to type IIa with features of strong plastic deformation. The studied sample is represented by Ca-poor Cr-pyrope of harzburgitic (H) paragenesis from Snap Lake dyke, Canada The garnet had been previously reported to contain Si = 3.16 apfu. The revised examination of the sample, resulted in detection of extremely fine-grained symplectite consisting of low Ca-orthopyroxene, clinopyroxene, Cr-spinel and coesite completely located and isolated in the inner part of the garnet crystal, which forms a sharp interface with the surrounding homogeneous garnet. XRD study confirmed the presence of the minerals constituting the symplectite. EPMA showed an identical bulk chemistry of the nanometer-sized symplectite and garnet. Further polishing of the garnet inclusion on the same surface with diamond removed the symplectite, which possibly was present as a thin lens within garnet. The remaining garnet is completely homogeneous as checked by two profiles, and contains unusually high Ni (118.2 ppm) and depleted REE patterns. Estimated PT formation conditions of this garnet are 10.8 GPa and 1450 °C within asthenosphere. Symplectite testifies partial retrograde isochemical phase transformation of the examined garnet which is suggested to be caused by decompression along with plastic deformation of diamond within the coesite stability field at T > 1000 °C and depth no less than 100 km. Because previously published studies of rare majoritic garnets composition were performed by EPMA only, it is possible that the traces of partial phase transformation (symplectite formation) could have been overlooked without additional XRD and/or TEM/AEM studies.

    Over the recent years, climate change impacts have been increasingly studied at the watershed scale. However, the impact assessment is strongly dependent upon the performance of the climatic and hydrological models. This study developed a two-step method to assess climate change impacts on water resources based on the Providing Regional Climates for Impacts Studies (PRECIS) modeling system and a Hydrological Inference Model (HIM). PRECIS runs provided future temperature and precipitation projections for the watershed under the Intergovernmental Panel on Climate Change SRES A2 and B2 emission scenarios. The HIM based on stepwise cluster analysis is developed to imitate the complex nonlinear relationships between climate input variables and targeted hydrological variables. Its robust mathematical structure and flexibility in predictor selection makes it a desirable tool for fully utilizing various climate modeling outputs. Although PRECIS and HIM cannot fully cover the uncertainties in hydro-climate modeling, they could provide efficient decision support for investigating the impacts of climate change on water resources. The proposed method is applied to the Grand River Watershed in Ontario, Canada. The model performance is demonstrated with comparison to observation data from the watershed during the period 1972-2006. Future river discharge intervals that accommodate uncertainties in hydro-climatic modeling are presented and future river discharge variations are analyzed. The results indicate that even though the total annual precipitation would not change significantly in the future, the inter-annual distribution is very likely to be altered. The water availability is expected to increase in Winter while it is very likely to decrease in Summer over the Grand River Watershed, and adaptation strategies would be necessary.

This study intends to investigate into the causes of hikikomori which is increasing worldwide phenomenon. The methodology is a case study approach located in an interpretive paradigm. The data was mainly collected through e-mails with the participant and phone conversations with his mother. The participant was a ‘hiki­ko­morian’ who was invited to investigate his own problem and further to be the co-author of this paper. The literature findings and this case study were then conceptualized into a more wide-ranging framework in compre­hen­ding the process of hikikomorization. The result appears to show that hikikomorization involves three processes: first, a predisposed introverted personality; second, the effects of multiple environmental factors such as family, school and society; and finally, the trigger point, such as the end of schooling or a stressful event. The study offers implications for other hiki­ko­mo­rians in better understanding of their problems and for practitioners working with reclusive ado­lescents and their families.

    Canada did not develop strong ties with the Third World until well after World War II. Three factors that have channeled and limited Canada's relationships with developing nations--location, history, and internal political relationships--are discussed. Also examined are patterns of Canadian foreign aid and investment and peace-seeking efforts. (RM)

    Since the 1990s, reports of Q fever in Nova Scotia, Canada, have declined. Passive surveillance for Q fever in Nova Scotia and its neighboring provinces in eastern Canada indicates that the clinical manifestation of Q fever in the Maritime provinces is pneumonia and that incidence of the disease may fluctuate.

    Guided by the extended parallel process model (EPPM) and reactance theory, this study examined the relationship between efficacy beliefs, reactance, and adult smokers' responses to pictorial health warning labels (HWL) on cigarette packaging, including whether efficacy beliefs or reactance modify the relationship between HWL responses and subsequent smoking cessation behavior. Four waves of data were analyzed from prospective cohorts of smokers in Australia and Canada (n = 7,120 observations) over a period of time after implementation of more prominent, pictorial HWLs. Three types of HWL responses were studied: psychological threat responses (i.e., thinking about risks from smoking), forgoing cigarettes due to HWLs, and avoiding HWLs. The results from Generalized Estimating Equation models indicated that stronger efficacy beliefs and lower trait reactance were significantly associated with greater psychological threat responses to HWLs. Similar results were found for models predicting forgoing behavior, although response efficacy was inversely associated with it. Only response efficacy was significantly associated with avoiding HWLs, showing a positive relationship. Higher self-efficacy and stronger responses to HWLs, no matter the type, were associated with attempting to quit in the follow-up period; reactance was unassociated. No statistically significant interactions were found. These results suggest that stronger efficacy beliefs and lower trait reactance are associated with some stronger responses to fear-arousing HWL responses; however, these HWL responses appear no less likely to lead to cessation attempts among smokers with different levels of self-efficacy to quit, of response efficacy beliefs, or of trait reactance against attempts to control their behavior.

    The GEOgraphic Object-Based Image Analysis (GEOBIA) paradigm continues to prove its efficacy in remote sensing image analysis by providing tools which emulate human perception and combine analyst's experience with meaningful image-objects. However, challenges remain in the evolution of this new paradigm as sophisticated methods attempt to deliver on the goal of automated geo-intelligence (i.e., geospatial content within context) from geospatial sources. In order to generate geo-intelligence from a forest scene, this article introduces a GEOBIA framework to estimate canopy height, above-ground biomass (AGB) and volume by combining lidar (light detection and ranging) transects, Quickbird imagery and machine learning algorithms. This framework is comprised three main components: (i) image-object extraction, (ii) lidar transect selection, and (iii) forest parameter generalization. The rational for integrating these methods is to provide a semi-automatic GEOBIA approach from which detailed forest information is obtained at the individual tree crown or small tree cluster level (i.e., mean object size of 0.04 ha); while also dramatically reducing airborne lidar data acquisition costs. Analysis is performed over a 16,330 ha forested study site in Quebec, Canada. Forest parameter estimation results derived from our GEOBIA framework demonstrate a strong relationship with those using the full lidar cover; where the highest estimates for canopy height ( R = 0.85; RMSE = 3.37 m), AGB ( R = 0.85; RMSE = 39.48 Mg/ha) and volume ( R = 0.85; RMSE = 52.59 m 3/ha) were achieved using a lidar transect sample representing only 7.6% of the total study area.

    Full Text Available Abstract Background Using a cohort of British Columbian male sawmill workers, we conducted a nested case-control study of the impact of rural compared to urban residence as well as rural/urban migration patterns in relation to hospitalization for non-work injury. We postulate that for many types of non-work injuries, rates will be higher in rural communities than in urban ones and that rates will also be higher for workers who migrate from urban to rural communities. Methods Using conditional logistic regression, univariate models were first run with each of five non-work injury outcomes. These outcomes were hospitalizations due to assault, accidental poisoning, medical mis-adventure, motor vehicle trauma, and other non-work injuries. In multivariate models marital status, ethnicity, duration of employment, and occupation were forced into the model and associations with urban, compared to rural, residence and various urban/migration patterns were tested. Results Urban or rural residence and migration status from urban to other communities, and across rural communities, were not associated with hospitalization for medical misadventure, assault, or accidental poisoning. The likelihood of a rural resident being hospitalized for motor vehicle trauma is higher than for an urban resident. The likelihood that a rural resident is hospitalized for "other" non-work injury is higher than for an urban resident. Conclusion In a relatively homogenous group of workers, and using a rigorous study design, we have demonstrated that the odds of other non-work injury are much higher for workers resident in and migrating to rural regions of Canada than they are for workers resident in or migrating to urban places.

    This presentation examined how the mining industry is adapting to recruiting and maintaining female employees in fly-in-fly-out (FIFO) operations. The FIFO mining model fulfills the economic, social and workforce needs of the modern mining industry. It is used in countries such as Canada and Australia. Most FIFO employees work long shifts in compacted work schedules. As such, they have long periods of time off, depending on the number of days they stay on site. The main advantages and disadvantages of working in a FIFO mine were identified. While the FIFO model can create opportunities for young women, it is typically seen as rigid and very challenging for women and employees with young families or workers who are single parents. The model is incompatible with starting a family and caring for small children. This study examined the major sources of stress associated with FIFO working schedules and presented recommendations to improve the system in order to increase the ability of mining companies to hire and retain women of all age groups while achieving corporate objectives and human resource needs. The preliminary recommendations from this study were to establish reliable standards and policies regarding maternity and family issues; improve the flexibility in schedules for pregnant women or women who just returned from maternity leave; establish mentorship programs and creative personnel policies that support employees with young families; and, establish orientation programs for new employees and their families. It was concluded that there needs to be a larger and more inclusive discussion of opportunities and challenges of FIFO operations and how they could be improved for everyone. refs., tabs., figs.

    Full Text Available The United Nations estimates that the global population is going to be double in the coming 40 years, which may cause a negative impact on the environment and human life. Such an impact may instigate increased water demand, overuse of power, anthropogenic noise, etc. Thus, modelling the Urban Environmental Quality (UEQ becomes indispensable for a better city planning and an efficient urban sprawl control. This study aims to investigate the ability of using remote sensing and Geographic Information System (GIS techniques to model the UEQ with a case study in the city of Toronto via deriving different environmental, urban and socio-economic parameters. Remote sensing, GIS and census data were first obtained to derive environmental, urban and socio-economic parameters. Two techniques, GIS overlay and Principal Component Analysis (PCA, were used to integrate all of these environmental, urban and socio-economic parameters. Socio-economic parameters including family income, higher education and land value were used as a reference to assess the outcomes derived from the two integration methods. The outcomes were assessed through evaluating the relationship between the extracted UEQ results and the reference layers. Preliminary findings showed that the GIS overlay represents a better precision and accuracy (71% and 65%, respectively, comparing to the PCA technique. The outcomes of the research can serve as a generic indicator to help the authority for better city planning with consideration of all possible social, environmental and urban requirements or constraints.

    Canada Basin of the Arctic Ocean is the least studied ocean basin in the World. Marine seismic field programs were conducted over the past 6 years using Canadian and American icebreakers. These expeditions acquired more than 14,000 line-km of multibeam bathymetric and multi-channel seismic reflection data over abyssal plain, continental rise and slope regions of Canada Basin; areas where little or no seismic reflection data existed previously. Canada Basin is a turbidite-filled basin with flat-lying reflections correlateable over 100s of km. For the upper half of the sedimentary succession, evidence of sedimentary processes other than turbidity current deposition is rare. The Canadian Archipelago and Beaufort Sea margins host stacked mass transport deposits from which many of these turbidites appear to derive. The stratigraphic succession of the MacKenzie River fan is dominated by mass transport deposits; one such complex is in excess of 132,000 km2 in area and underlies much of the southern abyssal plain. The modern seafloor is also scarred with escarpments and mass failure deposits; evidence that submarine landsliding is an ongoing process. In its latest phase of development, Canada Basin is geomorphologically confined with stable oceanographic structure, resulting in restricted depositional/reworking processes. The sedimentary record, therefore, underscores the significance of mass-transport processes in providing sediments to oceanic abyssal plains as few other basins are able to do.

    The objectives of this study were to evaluate the cost-effectiveness and budget impact of octaplasLG(®) compared with fresh-frozen plasma (FFP) in all patients receiving a transfusion in Canada. A decision analytic framework was used to model acute and long-term complications that could follow plasma transfusion. Over a life time horizon, the cost with octaplasLG(®) were CA$612.91, which is CA$303.14 less than those with FFP. OctaplasLG(®) resulted in 0.021 quality adjusted life years (QALYs) gained in comparison with FFP. Because of higher efficacy and lower costs, octaplasLG(®) is expected to be the dominant treatment option over FFP in Canada.

    Many attempts to implement resource management initiatives in Canadian and international communities have been resisted by stakeholders despite inclusion of their representatives in the decision-making process. Managers' failure to understand stakeholders' perspectives when proposing initiatives is a potential cause of this resistance. Our study uses marketing thought to enhance stakeholder theory by bringing in an audience-centric perspective. We attempt to understand how stakeholders perceive their interests in an organization and consequently decide how to influence that organization. By doing so, we investigate whether a disconnect exists between the perceptions of managers and those of stakeholders. Natural resource managers can utilize this knowledge to garner stakeholder support for the organization and its activities. We support this claim with findings from a water transfer plebiscite held in the Canadian province of Alberta. Sixteen personal interviews employing narrative inquiry were conducted to document voters' (i.e., irrigators') interpretations.

  1. The characteristics and experience of community food program users in arctic Canada: a case study from Iqaluit, Nunavut

    2012-06-01

    Full Text Available Abstract Background Community food programs (CFPs, including soup kitchens and food banks, are a recent development in larger settlements in the Canadian Arctic. Our understanding of utilization of these programs is limited as food systems research has not studied the marginalised and transient populations using CFPs, constraining service planning for some of the most vulnerable community members. This paper reports on a baseline study conducted with users of CFPs in Iqaluit, Nunavut, to identify and characterize utilization and document their food security experience. Methods Open ended interviews and a fixed-choice survey on a census (n = 94 were conducted with of users of the food bank, soup kitchen, and friendship centre over a 1 month period, along with key informant interviews. Results Users of CFPs are more likely to be Inuit, be unemployed, and have not completed high school compared to the general Iqaluit population, while also reporting high dependence on social assistance, low household income, and an absence of hunters in the household. The majority report using CFPs for over a year and on a regular basis. Conclusions The inability of users to obtain sufficient food must be understood in the context of socio-economic transformations that have affected Inuit society over the last half century as former semi-nomadic hunting groups were resettled into permanent settlements. The resulting livelihood changes profoundly affected how food is produced, processed, distributed, and consumed, and the socio-cultural relationships surrounding such activities. Consequences have included the rising importance of material resources for food access, the weakening of social safety mechanisms through which more vulnerable community members would have traditionally been supported, and acculturative stress. Addressing these broader challenges is essential for food policy, yet CFPs also have an essential role in providing for those who would

    Full Text Available Understanding the dynamic of metals in soil and plantsis essential for ecosystem management and risks assessment of environmental pollution and sustainability.The main objective of the present study is to determine the mobility of Ni, Cu, Fe, Mg and Zn in soil and their translocation in D. cespitosa plants in a mining region in Northern Ontario.The total amount of Cu, Ni, Fe, Mg and Zn were significantly higher in the top horizon (LFH compared to the adjacent layer Ae. The vertical distribution of metals in soil varied with the type of metals. The results of this study indicated that only a small portion of total metal was bioavailable to plants. The enrichment factor values for the targeted elements were far above the value of contamination resulting in high availability and distribution of metals in soil. The average bioconcentration/bioaccumulation factors (metal concentration ratio of plant roots to soil was high and varied from 3.1 to 40 for Cu, 24.5 to 91.6 for Fe, 18.2 to 398.6 for Mg, 10.3 to 75.5 for Ni and 24.9 to 73 for Zn. The translocation factor values were very low for the five metals. They ranged from 0.05 to 0.46 for Cu, 0.03 to 0.1 for Fe, 0.28 to 1.48 for Mg, 0.15 to 0.38 for Ni and 0.68 to 1.16 for Zn. Based on existing classification, Deschampsia. cespitosa is an excluder as it has high levels of metals in the roots but with a shoot/root ratio less than 1. This plant has a high potential for phytoextraction of metals from Northern Ontario soils.

    With the growth of the low altitude remote sensing (LARS) industry in recent years, their practical application in precision agriculture seems all the more possible. However, only a few scientists have reported using LARS to monitor crop conditions. Moreover, there have been concerns regarding the feasibility of such systems for producers given the issues related to the post-processing of images, technical expertise, and timely delivery of information. The purpose of this study is to showcase actual requests by farmers to monitor crop conditions in their fields using an unmanned aerial vehicle (UAV). Working in collaboration with farmers in northeastern Ontario, we use optical and near-infrared imagery to monitor fertilizer trials, conduct crop scouting and map field tile drainage. We demonstrate that LARS imagery has many practical applications. However, several obstacles remain, including the costs associated with both the LARS system and the image processing software, the extent of professional training required to operate the LARS and to process the imagery, and the influence from local weather conditions (e.g. clouds, wind) on image acquisition all need to be considered. Consequently, at present a feasible solution for producers might be the use of LARS service provided by private consultants or in collaboration with LARS scientific research teams.

    Ocean acidification caused by rising atmospheric CO₂ is predicted to negatively impact growth and calcification rates of coralline algae. Decreases in coralline abundance may have cascading effects on marine ecosystems and on carbon sequestration worldwide. In this study, we measured growth and calcification rates of three common species of articulated coralline algae (Bossiella plumosa, Calliarthron tuberculosum, and Corallina vancouveriensis) at an intertidal field site in British Columbia. Linear growth rates measured in the field were slow, although Bossiella grew significantly faster (0.22 cm mon⁻¹) than Calliarthron and Corallina (0.17 and 0.15 cm mon⁻¹, respectively). Growth rates in the field were generally slower than growth rates in the laboratory, suggesting that data generated in the laboratory may not be representative of natural field conditions. Growth rates did not decrease as fronds approached their maximum observed size, suggesting that maximum frond size might be determined not by intrinsic factors but by external factors such as wave-induced drag forces. Using growth data, we estimate that the largest observed Bossiella frond (20 cm²) and Calliarthron frond (40 cm²) were about 4- and 11-years-old, respectively, and had deposited approximately 1 and 6 g CaCO₃ in that time. Given the great abundance of coralline algae along the coast of British Columbia, deposition rates of CaCO₃ are expected to play a significant but poorly characterized role in carbon sequestration.

    Full Text Available Background: Primary care in remote communities in northern Canada is delivered primarily by nurses who receive clinical support from physicians in regional centres and the patient transportation system. To improve continuity, quality and access to care in remote northern communities, it is important to understand the perspectives of front-line providers and the complex challenges they face. Objective: To design and implement a survey of primary care providers to identify issues relating to inter-professional communication, clinical support and patient evacuation. Methods: In collaboration with the territorial government and regional health authority partners, we developed a 21-item self-administered questionnaire survey, which could be completed online. The survey was sent to 218 physicians and nurses who were employed in the Northwest Territories (NWT at the time of the survey and were involved in sending patients out of the community and/or receiving patients. The survey also contained an open-ended question at the end seeking comments regarding primary health care. Results: The overall low response rate of 39% among nurses and 19% among physicians threatens the validity of the quantitative results. The majority of providers were satisfied with their ability to communicate with other providers in a timely manner, their freedom to make clinical decisions and their overall experience practicing in the NWT. The patient transfer system appears to work from both the sender and receiver perspectives. However, a common theme reported by nurses was that physicians providing clinical advice, especially short-term locums, were not familiar with the local situation, whilst physicians at the receiving end remarked that the clinical information provided to them often lacked clarity. Conclusions: Important lessons were learnt from the pilot study, especially in better engagement of providers in planning and dissemination. The questionnaire design and the

    Objectives We assessed stakeholder perceptions on the use of an electronic consultation system (e-Consult) to improve the delivery of kidney care in Alberta. We aim to identify acceptability, barriers and facilitators to the use of an e-Consult system for ambulatory kidney care delivery. Methods This was a qualitative focus group study using a thematic analysis design. Eight focus groups were held in four locations in the province of Alberta, Canada. In total, there were 72 participants in two broad stakeholder categories: patients (including patients' relatives) and providers (including primary care physicians, nephrologists, other care providers and policymakers). Findings The e-Consult system was generally acceptable across all stakeholder groups. The key barriers identified were length of time required for referring physicians to complete the e-Consult due to lack of integration with current electronic medical records, and concerns that increased numbers of requests might overwhelm nephrologists and lead to a delayed response or an unsustainable system. The key facilitators identified were potential improvement of care coordination, dissemination of best practice through an educational platform, comprehensive data to make decisions without the need for face-to-face consultation, timely feedback to primary care providers, timeliness/reduced delays for patients' rapid triage and identification of cases needing urgent care and improved access to information to facilitate decision-making in patient care. Conclusions Stakeholder perceptions regarding the e-Consult system were favourable, and the key barriers and facilitators identified will be considered in design and implementation of an acceptable and sustainable electronic consultation system for kidney care delivery.

    Pierrick Bedouch

    Full Text Available BACKGROUND: Asthma-related health resource use and costs may be influenced by increasing asthma prevalence, changes to asthma management guidelines, and new medications over the last decade. The objective of this work was to analyze direct asthma-related medical costs, and trends in total and per-patient costs of hospitalizations, physician visits, and medications. METHODS: A cohort of asthma patients from British Columbia (BC, Canada, was created. Asthma patients were identified using a validated case definition. Costs for hospitalizations, physician visits, and medications were calculated from billing records (in 2008 Canadian dollars. Trends in total and per-patient costs over the study period were analyzed using Generalized Linear Models. RESULTS: 398,235 patients satisfied the asthma case definition (mid-point prevalence 8.0%. Patients consumed $315.9 million (M in direct asthma-related health resources between 2002 and 2007. Hospitalizations, physician visits, and medication costs accounted for 16.0%, 15.7% and 68.2% of total costs, respectively. Cost of asthma increased from $49.4 M in 2002 to $54.7 M in 2007. Total annual costs attributable to hospitalizations and physician visits decreased (-39.8% and -25.5%, respectively; p<0.001, while medication costs increased (+38.7%; p<0.001. INTERPRETATION: This population-based analysis shows that the total direct cost of asthma in BC has increased since 2002, mainly due to a rise in asthma prevalence and cost of medication. Combination therapy with inhaled corticosteroids/long-acting beta-agonists has become a significant component of the cost of asthma. Although billing records capture only a fraction of the true burden of asthma, the simultaneous increase in medication costs and reductions in hospitalization and physician visit costs provides valuable insight for policy makers into the shifts in asthma-related resource use.

    Full Text Available Objective: The objective of this qualitative descriptive study was to explore the perceptions of women living in inner-city Winnipeg, Canada, about barriers, facilitators, and motivators related to their use of prenatal care. Methods: Individual, semi-structured interviews were conducted in person with 26 pregnant or postpartum women living in inner-city neighborhoods with high rates of inadequate prenatal care. Interviews averaged 67 min in length. Recruitment of participants continued until data saturation was achieved. Inductive content analysis was used to identify themes and subthemes under four broad topics of interest (barriers, facilitators, motivators, and suggestions. Sword’s socio-ecological model of health services use provided the theoretical framework for the research. This model conceptualizes service use as a product of two interacting systems: the personal and situational attributes of potential users and the characteristics of health services. Results: Half of the women in our sample were single and half self-identified as Aboriginal. Participants discussed several personal and system-related barriers affecting use of prenatal care, such as problems with transportation and child care, lack of prenatal care providers, and inaccessible services. Facilitating factors included transportation assistance, convenient location of services, positive care provider qualities, and tangible rewards. Women were motivated to attend prenatal care to gain knowledge and skills and to have a healthy baby. Conclusion: Consistent with the theoretical framework, women’s utilization of prenatal care was a product of two interacting systems, with several barriers related to personal and situational factors affecting women’s lives, while other barriers were related to problems with service delivery and the broader healthcare system. Overcoming barriers to prenatal care and capitalizing on factors that motivate women to seek prenatal care

    Full Text Available Background: Access to adequate quantities of water has a protective effect on human health and well-being. Despite this, public health research and interventions are frequently focused solely on water quality, and international standards for domestic water supply minimums are often overlooked or unspecified. This trend is evident in Inuit and other Arctic communities even though numerous transmissible diseases and bacterium infections associated with inadequate domestic water quantities are prevalent. Objectives: Our objective was to explore the pathways by which the trucked water distribution systems being used in remote northern communities are impacting health at the household level, with consideration given to the underlying social and environmental determinants shaping health in the region. Methods: Using a qualitative case study design, we conducted 37 interviews (28 residents, 9 key informants and a review of government water documents to investigate water usage practices and perspectives. These data were thematically analysed to understand potential health risks in Arctic communities and households. Results: Each resident receives an average of 110 litres of municipal water per day. Fifteen of 28 households reported experiencing water shortages at least once per month. Of those 15, most were larger households (5 people or more with standard sized water storage tanks. Water shortages and service interruptions limit the ability of some households to adhere to public health advice. The households most resilient, or able to cope with domestic water supply shortages, were those capable of retrieving their own drinking water directly from lake and river sources. Residents with extended family and neighbours, whom they can rely on during shortages, were also less vulnerable to municipal water delays. Conclusions: The relatively low in-home water quantities observed in Coral Harbour, Nunavut, appear adequate for some families. Those living in

    Rates of mammography screening for breast cancer are disproportionately low in certain subgroups including low-income and immigrant women. The purpose of the study was to examine differences in rates of appropriate breast cancer screening (i.e., screening mammography every 2 years) among Ontario immigrant women by world region of origin and explore the association between appropriate breast cancer screening among these women groups and individual and structural factors. A cohort of 183,332 screening-eligible immigrant women living in Ontario between 2010 and 2012 was created from linked databases and classified into eight world regions of origin. Appropriate screening rates were calculated for each region by age group and selected sociodemographic, immigration, and healthcare-related characteristics. The association between appropriate screening across the eight regions of origin and selected sociodemographic, immigration, and health-related characteristics was explored using multivariate Poisson regression. Screening varied by region of origin, with South Asian women (48.5%) having the lowest and Caribbean and Latin American women (63.7%) the highest cancer screening rates. Factors significantly associated with lower screening across the world regions of origin included living in the lowest income neighborhoods, having a refugee status, being a new immigrant, not having a regular physical examination, not being enrolled in a primary care patient enrollment model, having a male physician, and having an internationally trained physician. Multiple interventions entailing cross-sector collaboration, promotion of patient enrollment models, community engagement, comprehensive and intensive outreach to women, and knowledge translation and transfer to physicians should be considered to address screening disparities among immigrant population. Consideration should be given to design and delivery of culturally appropriate and easily accessible cancer screening programs

    The Mackenzie River in the Northwest Territories, Canada, with its headstreams the Peace and Finley, is the longest river in North America at 4241 km, and drains an area of 1,805,000 square km. The large marshy delta provides habitat for migrating Snow Geese, Tundra Swans, Brant, and other waterfowl. The estuary is a calving area for Beluga whales. The Mackenzie (previously the Disappointment River) was named after Alexander Mackenzie who travelled the river while trying to reach the Pacific in 1789. The image was acquired on August 4, 2005, covers an area of 55.8 x 55.8 km, and is located at 68.6 degrees north latitude, 134.7 degrees west longitude.

    , and the calibration process has provided important insight to key factors controlling massive slope mechanics. Through numerical studies it has been shown that the three-dimensional interpretation of basal slip surface geometry and spatial heterogeneity in shear zone stiffness are important factors controlling large-scale slope deformation processes. The role of secondary internal shears and the interaction between landslide morphological zones has also been assessed. Further, numerical simulation of changing groundwater conditions has produced reasonable correlation with field observations. Calibrated models are valuable tools for the forward prediction of landslide dynamics. Calibrated Downie Slide models have been used to investigate how trigger scenarios may accelerate deformations at Downie Slide. The ability to reproduce observed behaviour and forward test hypothesized changes to boundary conditions has valuable application in hazard management of massive landslides. The capacity of decision makers to interpret large amounts of data, respond to rapid changes in a system and understand complex slope dynamics has been enhanced.

    During the past 150 years, most of the modern day creeks were the target of miners roaming the Cariboo Mountains, British Columbia, in the search for placer gold. In these days, the probability to locate new placer gold occurrence in recent river beds is therefore substantially reduced. New, promising exploration targets appear to be channels mostly buried under alluvial cover sediments. It is airborne geophysical methods that can reveal hidden channels fast and cost-effectively as these penetrate the sub-surface contactless and reflect physical properties of the sub-surface, such as electric conductivity and magnetic susceptibility or magnetization, respectively. We applied the airborne geophysical exploration approach on four exploration areas in the Cariboo gold district. Helicopter-borne transient electromagnetic (TEM) and magnetic data were flown using the SkyTEM system. To our knowledge, it has been innovatory to apply high resolution, high density airborne geophysics in the search for placer gold deposited in pre-Holocene sedimentary channel fills of the Cariboo Mountains. A particular effort of our studies aimed at the Mary creek claims which straddle the boundary of the Quesnel and Kootenay terranes of the Canadian Cordillera and include the dormant Toop mine situated in the Mary creek area known for many finds of coarse nugget from the pre-glacial buried Toop channel. Our objective was to locate the southbound extension of the channel buried in Pleistocene sediments of the Toop plateau. Careful analysis of the airborne geophysical data sets provided indications from both the TEM and magnetic data sets favouring the existence of a hidden channel beneath the plateau. The evaluation of seven reverse circulation (RC) drill holes sunk into a promising elongated narrow conductor beneath the plateau was not conclusive as not clearly showing the sedimentary pattern of a channel with gravels typically at its bottom.

    The results of a study to determine if chronic exposure to emissions from the oil and gas industry influence the health and reproductive performance of cattle and wildlife in western Canada was presented. Individual cows in herds from Alberta, Saskatchewan and northeastern British Columbia were monitored in pens and pastures to determine their exposure status. Data on other known risk factors such as the cow's age, breed and body condition were collected. The study measured concentrations of sulphur dioxide (SO{sub 2}); hydrogen sulphide (H{sub 2}S); and volatile organic compounds (VOCs) measured as benzene and toluene. Passive air monitors were located on all occupied pastures and wintering areas for each herd. Information on the location of over 39,000 animals from 205 herds on 3355 different parcels of land was recorded at 2 week intervals. Each animal's exposure was then averaged to create cumulative exposure values for biologically relevant risk periods for each outcome. Exposures to fine particulate matter (PM) and polycyclic aromatic hydrocarbons were measured a total of 365 times near the calving area for 32 herds. Five primary health outcomes were studied: (1) nonpregnancy; (2) length of breeding-to-calving interval; (3) abortion; (4) stillbirth; and (5) calf mortality. No associations were found among any of the exposure measures and the risk of nonpregnancy, abortion or stillbirth. Sulphur-containing exposures showed no associations with secondary outcome measures in the respiratory, immune and nervous systems. An association was found between exposure to SO{sub 2} and the increased risk of calf mortality. Findings also suggested that there was a greater risk of lesions in the calf skeletal or cardiac muscle with increased prenatal exposure to SO{sub 2}. Increased exposure to VOCs contributed to a greater risk of calf respiratory and thyroid lesions, and a lower count of CD4 and CD8 T-lymphocytes in calves. The results of a concurrent study on

    Full Text Available The winter regime of river-ice covers in high northern latitude regions is often a determining factor in the management of water resources, conservation of aquatic ecosystems and preservation of traditional and cultural lifestyles of local peoples. As ground-based monitoring of river-ice regimes in high northern latitudes is expensive and restricted to a few locations due to limited accessibility to most places along rivers from shorelines, remote sensing techniques are a suitable approach for monitoring. This study developed a RADARSAT-2 based method to monitor the spatio-temporal variation of ice covers, as well as ice types during the freeze-up period, along the main channel of the Slave River Delta in the Northwest Territories of Canada. The spatio-temporal variation of ice covers along the river was analyzed using the backscatter-based coefficient of variation (CV in the 2013–2014 and 2014–2015 winters. As a consequence of weather and flow conditions, the ice cover in the 2013–2014 winter had the higher variation than the 2014–2015 winter, particularly in the potential areas of flooded/cracked ice covers. The river sections near active channels (e.g., Middle Channel and Nagle Channel, Big Eddy, and Great Slave Lake also yielded higher intra-annual variation of ice cover characteristics during the winters. With the inclusion of backscatter and texture analysis from RADARSAT-2 data, four water and ice cover classes consisting of open water, thermal ice, juxtaposed ice, and consolidated ice, were discriminated in the images acquired between November and March in both the studied winters. In addition to river geomorphology and climatic conditions such as river width, sinuosity or air temperature, the fluctuation of water flows during the winter has a significant impact on the variation of ice cover as well as the formation of different ice types in the Slave River. The RADARSAT-2 based monitoring algorithm can also be applied to other

    Full Text Available Abstract Objectives Endometriosis has been believed to increase the risk of developing ovarian cancer, but recent data supporting this hypothesis are lacking. The aim of this study was to verify whether the incidence of endometriosis, ovarian cancer and the both increased during the last 10 years among women living in the Estrie region of Quebec. Methods We collected data of women diagnosed with endometriosis, ovarian cancer or both, between 1997 and 2006, from a population living in the Estrie region of Quebec. We performed this retrospective cross-sectional study from the CIRESSS (Centre Informatisé de Recherche Évaluative en Services et Soins de Santé system, the database of the CHUS (Centre Hospitalier Universitaire of Sherbrooke, Sherbrooke, Canada. Results Among the 2854 identified patients, 2521 had endometriosis, 292 patients had ovarian cancer and 41 patients had both ovarian cancer and endometriosis. We showed a constant increase in the number of ovarian cancer (OC between 1997 and 2006 (r2 = 0.557, P = 0.013, which is not the case for endometriosis (ENDO or endometriosis-associated ovarian cancer (EAOC. The mean age ± SD was 40.0 ± 9.9 and 53.9 ± 11.4 for patients having ENDO and OC, respectively. Mean age of women with EAOC was 48.3 ± 10.8, suggesting an early onset of ovarian cancer in women having endometriosis of about 5.5 years average, P = 0.003. Women with ENDO were at increased risk for developing OC (Rate Ratio [RR] = 1.6; 95% Confidence Interval [CI] = 1.12-2.09. Pathological analyses showed the predominance of endometrioid type (24.4% and clear-cell type (21.9% types in EAOC compared to OC, P = 0.0070 and 0.0029, respectively. However, the serous type is the most widespread in OC (44.5% in comparison to EAOC (19.51%, P = 0.0023. Conclusion Our findings highlight that the number of cases of ovarian cancer is constantly increasing in the last ten years and that endometriosis represents a serious risk factor which

    Obstetric medicine is a growing area of interest within internal medicine in Canada. Canadians continue to travel broadly to obtain relevant training, particularly in the United Kingdom. However, there is now a sufficient body of expertise in Canada that a cadre of 'home-grown' obstetric internists is emerging and staying within Canada to improve maternity care. As this critical mass of practitioners grows, it is apparent that models of obstetric medicine delivery have developed according to local needs and patterns of practice. This article aims to describe the state of obstetric medicine in Canada, including general internal medicine services as the rock on which Canadian obstetric medicine has been built, the Canadian training curriculum and opportunities, organisation of obstetric medicine service delivery and the future.

    This paper investigates the impact that a federal government structure has on strategic selection of renewable energy policy instruments. The context for this study centers on wind power development in Canada. Canada is a nation that is blessed by all the attributes necessary to catalyze global leadership in installed wind power capacity. Unfortunately, the constitutional separation of powers that underpins Canada's federal system impedes the creation of a national wind power development strategy because Canada's provinces have constitutional authority over electricity governance. The insights gleaned from the case study are used to develop a conceptual framework for understanding the impact that federal structure has on policy instrument selection and efficacy under areas of federal, regional and concurrent policy jurisdiction. Finally, this framework is re-applied to identify specific approaches the Canadian federal government could take to resolve what currently amounts to be a fragmented, ineffective approach to wind power development planning.

    Full Text Available This study investigates a two component decomposition technique for HH/VV-polarized PolSAR (Polarimetric Synthetic Aperture Radar data. The approach is a straight forward adaption of the Yamaguchi decomposition and decomposes the data into two scattering contributions: surface and double bounce under the assumption of a negligible vegetation scattering component in Tundra environments. The dependencies between the features of this two and the classical three component Yamaguchi decomposition were investigated for Radarsat-2 (quad and TerraSAR-X (HH/VV data for the Mackenzie Delta Region, Canada. In situ data on land cover were used to derive the scattering characteristics and to analyze the correlation among the PolSAR features. The double bounce and surface scattering features of the two and three component scattering model (derived from pseudo-HH/VV- and quad-polarized data showed similar scattering characteristics and positively correlated-R2 values of 0.60 (double bounce and 0.88 (surface scattering were observed. The presence of volume scattering led to differences between the features and these were minimized for land cover classes of low vegetation height that showed little volume scattering contribution. In terms of separability, the quad-polarized Radarsat-2 data offered the best separation of the examined tundra land cover types and will be best suited for the classification. This is anticipated as it represents the largest feature space of all tested ones. However; the classes “wetland” and “bare ground” showed clear positions in the feature spaces of the C- and X-Band HH/VV-polarized data and an accurate classification of these land cover types is promising. Among the possible dual-polarization modes of Radarsat-2 the HH/VV was found to be the favorable mode for the characterization of the aforementioned tundra land cover classes due to the coherent acquisition and the preserved co-pol. phase. Contrary, HH/HV-polarized and VV

    Full Text Available Abstract Background Increasing livestock density and animal manure spreading, along with climate factors such as heavy rainfall, may increase the risk of acute gastrointestinal illness (AGI. In this study we evaluated the association between farming activities, precipitation and AGI. Methods A cross-sectional telephone survey of randomly selected residents (n = 7006 of 54 rural municipalities in Quebec, Canada, was conducted between April 2007 and April 2008. AGI symptoms and several risk factors were investigated using a phone questionnaire. We calculated the monthly prevalence of AGI, and used multivariate logistic regression, adjusting for several demographic and risk factors, to evaluate the associations between AGI and both intensive farming activities and cumulative weekly precipitation. Cumulative precipitation over each week, from the first to sixth week prior to the onset of AGI, was analyzed to account for both the delayed effect of precipitation on AGI, and the incubation period of causal pathogens. Cumulative precipitation was treated as a four-category variable: high (≥90th percentile, moderate (50th to th percentile, low (10th to th percentile, and very low (th percentile precipitation. Results The overall monthly prevalence of AGI was 5.6% (95% CI 5.0%-6.1%, peaking in winter and spring, and in children 0-4 years old. Living in a territory with intensive farming was negatively associated with AGI: adjusted odds ratio (OR = 0.70 (95% CI 0.51-0.96. Compared to low precipitation periods, high precipitation periods in the fall (September, October, November increased the risk of AGI three weeks later (OR = 2.20; 95% CI 1.09-4.44 while very low precipitation periods in the summer (June, July, August increased the risk of AGI four weeks later (OR = 2.19; 95% CI 1.02-4.71. Further analysis supports the role of water source on the risk of AGI. Conclusions AGI poses a significant burden in Quebec rural municipalities with a peak in winter

    A highly sensitive instrument, a Laser-Excited Atomic Fluorescence Spectrometer, has been developed to study thallium contamination in some important Canadian ecosystems from the Arctic (containing very low thallium concentration) to coal-related industries across Canada and even to the study of thallium toxicity in an invertebrate, Hyalella azteca. Overall, the data indicate that the coal power plants and mines contain higher thallium concentrations than the other ecosystems studied, and the eastern region has the highest Tl concentrations compared to other regions. The range of thallium concentration in ng/L for the Arctic snow and ice was between not detected and 8.4, for the Great Lakes waters 0.9 to 48, for pore waters 0.1 to 213, for western coal power plants and mines 0.1 to 1326, for central coal power plants 1.2 to 175, for eastern coal power plants and mines 0.2 to 23605, and for miscellaneous sites across Canada not detected to 4390 ng/L. Some of these high concentrations and those high ones reported in industrial wastewaters exceeded the chronic toxicity endpoints for Hyalella azteca mortality, growth and reproduction, and thus can cause serious distress to the environment. All data were integrated into a map of thallium distribution, the first one in Canada. Natural background level of thallium for the Arctic was estimated to be 0.02 to 0.03 pg/g.

    It has been demonstrated, for many inherited diseases, that historical events have shaped the various regional gene pools of Eastern Canada. In so doing, it has given rise to the increased prevalence of some rare diseases due, to founder effects. The following neurogenetic disorders were first identified in patients from Eastern Canada: AOA-2, Arsacs, HSN-2, Arca-1, HMSN/ACC and Arsal. The population of Eastern Canada, we are convinced, will still allow the identification of new rare forms of hereditary ataxias, spastic parapareses and neuropathies as well as contribute to the uncovering of their mutated genes. We have summarized our current knowledge of the various hereditary ataxias, spastic parapareses and neuropathies in Eastern Canada. The study of the more common and homogenous features of these diseases has been largely completed.

    The Very Low Head (VLH) turbine is a recent turbine technology developed in Europe for low head sites in the 1.4 - 4.2 m range. The VLH turbine is primarily targeted for installation at existing hydraulic structures to provide a low impact, low cost, yet highly efficient solution. Over 35 VLH turbines have been successfully installed in Europe and the first VLH deployment for North America is underway at Wasdell Falls in Ontario, Canada. Deployment opportunities abound in Canada with an estimated 80,000 existing structures within North America for possible low-head hydro development. There are several new considerations and challenges for the deployment of the VLH turbine technology in Canada in adapting to the hydraulic, environmental, electrical and social requirements. Several studies were completed to determine suitable approaches and design modifications to mitigate risk and confirm turbine performance. Diverse types of existing weirs and spillways pose certain hydraulic design challenges. Physical and numerical modelling of the VLH deployment alternatives provided for performance optimization. For this application, studies characterizing the influence of upstream obstacles using water tunnel model testing as well as full-scale prototype flow dynamics testing were completed. A Cold Climate Adaptation Package (CCA) was developed to allow year-round turbine operation in ice covered rivers. The CCA package facilitates turbine extraction and accommodates ice forces, frazil ice, ad-freezing and cold temperatures that are not present at the European sites. The Permanent Magnet Generator (PMG) presents some unique challenges in meeting Canadian utility interconnection requirements. Specific attention to the frequency driver control and protection requirements resulted in a driver design with greater over-voltage capability for the PMG as well as other key attributes. Environmental studies in Europe included fish friendliness testing comprised of multiple in

    There are some 600 firms in Canada classified as metal finishers, employing about 8,000 people; 60 per cent of these firms are located in Ontario. Annual sales are in the range of $800 million. About 25 per cent of the total effort is devoted to the automotive industry. Regulatory initiatives are based on the Toxic Substance Management Policy 1995 Framework, and involve multi-stakeholder consultation to identify, evaluate and recommend goals, targets, and management options to reduce exposure to hexavalent chromium, maximize the recycling of nickel and minimize the releases of cadmium from industry operations by promoting and encouraging appropriate P2 practices. Other regulatory initiatives follow from the Fisheries Act of 1970, the Metal Finishing Liquid Effluent Guidelines of 1977, and the Canadian Environmental Protection Act of 1988. There are also non-regulatory initiatives, such as the Metal Finishing Industry Pollution Project, a voluntary cooperative effort directed towards formulating plans to reduce toxic effluents from metal finishing operations and to develop and implement site-specific P2 plans. The various treatment technologies such as physico-chemical treatment of multi-metal rinse waters and periodic bath dumpings at on-site waste water treatment plants, water reduction practices to make more effective use of rinse water, evaporation, ion exchange, packed bed scrubbers, fume suppressants, composite mesh pads and separate ventilation for degreasing are also described. Specific case studies are cited to illustrate the various treatment technologies.

    The history of education and legislation of traditional Chinese medicine (TCM) and acupuncture in Canada is short. The first school of TCM opened its door to the general public in Canada in 1985 and the first legislation of acupuncture was introduced in Alberta, Canada in 1988. Currently, TCM and/or acupuncture have been regulated in five provinces in Canada. The legislation and regulation, as well as education of TCM and acupuncture vary among the five provinces in Canada. Opportunities and challenges facing TCM education exist simultaneously. Strategies are proposed to develop an international standard for TCM education in Canada, and possibly in other English speaking countries as well.

    Staphylinidae (Rove Beetles) from northeastern North America deposited in the University of Guelph Insect Collection (Ontario, Canada) were curated from 2008-2010 by the first author. The identification of this material has resulted in the recognition of thirty-five new provincial or state records, six new Canadian records, one new record for the United States and two new records for eastern Canada. All records are for subfamilies other than Aleocharinae and Pselaphinae, which will be treated in future publications as collaborative projects. Range expansions of ten exotic species to additional provinces and states are reported. The known distributions of each species in northeastern North America are summarized and presented as maps, and those species with a distinctive habitus are illustrated with color photographs. Genitalia and/or secondary sexual characters are illustrated for those species currently only identifiable on the basis of dissected males. The majority of the new records are in groups that have been recently revised, demonstrating the importance of curation and local insect surveys to the understanding of biodiversity, even for taxa and areas considered 'relatively well-known'.

The identification of this material has resulted in the recognition of thirty-five new provincial or state records, six new Canadian records, one record for the United States and two new records for eastern Canada. All records are for subfamilies other than Aleocharinae and Pselaphinae, which will be treated in future publications as collaborative projects. Range expansions of ten exotic species to additional provinces and states are reported. The known distributions of each species in northeastern North America are summarized as maps and those species with a distinctive habitus are illustrated with color photographs. Genitalia and/or secondary sexual characters are illustrated for those species currently only identifiable on the basis of dissected males. The majority of the new records are in groups that have been recently revised, demonstrating the importance of curation and local insect surveys to the understanding of biodiversity, even for taxa and areas considered ‘relatively well-known’.

    2010-03-15

    This article presented the historical aspects regarding Canadian research in mineral processing and ore refining. It highlighted the career of Eugene Haanel, the first director of Canada's Department of Mines. The events that led to the creation of the Canadian Bureau of Mines and the Energy Branch at the turn of the 1900s were described along with the creation of the first assay office to deal with the large amounts of gold produced in British Columbia and the Yukon. In order to encourage the exploitation of Canada's iron ore deposits and the abundant electrical energy from Niagara Falls, Haanel organized a mission to Europe to study steel production using electric furnaces. He sought ways to secure a supply of the reducing agent and the fuel that metallurgical processes required in great quantities. Noting that Canada was spending millions to import coal and coke, he promoted the exploitation of the large deposits of peat in Ontario and Quebec. He also drew attention to the need to stop using wood as a fuel to conserve the forests. In 1905, the Mining Section was commissioned to evaluate nonferrous metal deposits in Canada, including lead-zinc, cobalt, asbestos, mica, graphite and raw materials for cement manufacture. Serious hydrometallurgical research in Canada began in 1921 at the Ministry of Mines, followed by pyrometallurgical research in 1922. The radioactivity division was created in 1948. The article also described the reorganization of extractive metallurgical research in Canada. 9 figs.

    The author retraces the history of trachoma in Canada. The numerous articles in Canadian medical journals from the middle of the 18th to the middle of the 19th century show the remarkable contribution of Canadian ophthalmologists. The clinical symptoms and signs followed by the etiology and the different modes of treatment are reviewed. The presence and prevention of trachoma in Canada, ranging from Montreal to Toronto, also in Halifax with the arrival of the transatlantic immigrants, as well as those reaching the western provinces of Canada are described. How the Canadian Department of Health belatedly introduced a prevention campaign only after a widespread dissemination of trachoma across the country is also examined.

    Regional and continental carbon stock and flux estimates differ among assessments depending on the scaling approach used and the budget components considered. This is particularly manifest across the vast circum-boreal region, which has experienced substantial modification of the major driving forces of the carbon cycle in recent decades, including pronounced climate warming and associated increases in the frequency and severity of disturbances. In Canada, inventory-based estimates suggest a small carbon sink for its managed forest, but do not include unmanaged lands nor capture major driving forces such as climate change and atmospheric chemistry. On the other hand, estimates from process-based models vary widely and often do not consider critical disturbance and management impacts. Here, we demonstrate results from an updated approach that integrates inventory-based information on management and disturbances with process-level representation of ecological dynamics using a terrestrial biogeochemistry model. The integrated approach facilitates more comprehensive diagnosis of Canada's land-based carbon budget within a framework that also allows for attribution of the major driving forces and prediction under future scenarios. Using this framework, we diagnose an approximately 30 Tg C yr-1 sink in Canada over the first decade of the 21st Century, which represents a significant reduction in the strength of the CO2 sink estimated for previous decades. This decline in sink strength is attributed primarily to CO2 emissions from the substantial area disturbed by wildfire and insect outbreaks in recent years. Such changes are predicted to create positive feedbacks to the climate system that accelerate global warming. Compared to other assessments, our results suggest that CO2 uptake by the region's ecosystems may not be as strong as estimated by atmospheric inverse approaches, which are highly uncertain over the high latitudes, or by process-based models that do not

    Ocean Networks Canada operates two large undersea observatories that collect, archive, and deliver data in real time over the Internet. These data contribute to our understanding of the complex changes taking place on our ocean planet. Ocean Networks Canada's VENUS was the world's first cabled seafloor observatory to enable researchers anywhere to connect in real time to undersea experiments and observations. Its NEPTUNE observatory is the largest cabled ocean observatory, spanning a wide range of ocean environments. Most recently, we installed a new small observatory in the Arctic. Together, these observatories deliver "Big Data" across many disciplines in a cohesive manner using the Oceans 2.0 data management and archiving system that provides national and international users with open access to real-time and archived data while also supporting a collaborative work environment. Ocean Networks Canada operates these observatories to support science, innovation, and learning in four priority areas: study of the impact of climate change on the ocean; the exploration and understanding the unique life forms in the extreme environments of the deep ocean and below the seafloor; the exchange of heat, fluids, and gases that move throughout the ocean and atmosphere; and the dynamics of earthquakes, tsunamis, and undersea landslides. To date, the Ocean Networks Canada archive contains over 130 TB (collected over 7 years) and the current rate of data acquisition is ~50 TB per year. This data set is complex and diverse. Making these "Big Data" accessible and attractive to users is our priority. In this presentation, we share our experience as a "Big Data" institution where we deliver simple and multi-dimensional calibrated data cubes to a diverse pool of users. Ocean Networks Canada also conducts extensive user testing. Test results guide future tool design and development of "Big Data" products. We strive to bridge the gap between the raw, archived data and the needs and

    Evidence-informed health policy making (EIHP) is becoming a necessary means to achieving health system reform. Although Canada has a rich and well documented history in the field of evidence-based medicine, a concerted effort to capture Canada's efforts to support EIHP in particular has yet to be realized. This paper reports on the development of EIHP in Canada, including promising approaches being used to support the use of evidence in policy making about complex health systems issues. In light of Canada's contributions, this paper suggests that scholars in Canada will continue engaging in the field of EIHP through further study of interventions underway, as well as by sharing knowledge within and beyond Canada's borders about approaches that support EIHP.

    2011-01-01

    Child maltreatment is a major public health problem associated with impairment in childhood, adolescence, and extending throughout the lifespan. Within Canada, high-quality child maltreatment studies have been conducted and are critical for informing prevention and intervention efforts. However, compared to other parts of the world (e.g., United States, United Kingdom, the Netherlands, and Mexico), the number of studies conducted in Canada is far fewer and the data used to study this important public health problem are less diverse. Importantly, to date, representative data on child maltreatment from the general population at the national level in Canada do not exist. This means that many questions regarding child maltreatment in Canada remain unanswered. To advance our understanding of child maltreatment in Canada and to make significant strides towards protecting Canadian children and families, research using Canadian data is essential. To begin to meet these important public health goals, we need to invest in collecting high-quality, nationally representative Canadian data on child maltreatment. Solutions for the barriers and challenges for the inclusion of child maltreatment data into nationally representative Canadian surveys are provided.

    The United States and Canada have been cooperating in all areas of energy exchange for many years. Electrical energy has been chosen to be the focus of this study because substantial means for exchanges offer benefits that have not yet been fully exploited. There may be some bilateral benefits from additional interconnections because of the buffers which they represent against domestic imbalances. After the history of the electricity exchanges between the two countries is reviewed, opportunities and incentives and obstacles and constraints are discussed in the next two chapters. The final chapter examines procedures to resolve obstacles and minimize constraints. (MCW)

We determined the risk of immune-mediated diseases in South Asian and other immigrants to Ontario, Canada, and their Ontario-born children.Population-based cohorts of patients with asthma, type 1 diabetes (T1DM, type 2 diabetes (T2DM, and inflammatory bowel disease (IBD were derived from health administrative data. We determined the standardized incidence, and the adjusted risk of these diseases in immigrants from South Asia, immigrants from other regions, compared with non-immigrant residents of Ontario. The risk of these diseases in the Ontario-born children of immigrants were compared to the children of non-immigrants.Compared to non-immigrants, adults from South Asia had higher risk of asthma (IRR 1.56, 95%CI 1.51-1.61 and T2DM (IRR 2.59, 95%CI 2.53-2.65. Adults from South Asia had lower incidence of IBD than non-immigrants (IRR 0.32, 95%CI 0.22-0.49, as did immigrants from other regions (IRR 0.29, 95%CI 0.20-0.42. Compared to non-immigrant children, the incidence of asthma (IRR 0.66, 95%CI 0.62-0.71 and IBD (IRR 0.47, 95%CI 0.33-0.67 was low amongst immigrant children from South Asia.

    2008-01-01

    Researchers measured exposure to oil and gas industry emissions in 205 cow-calf herds located in Western Canada. They measured airborne concentrations of sulfur dioxide, hydrogen sulfide, and volatile organic compounds with passive monitors placed in each pasture, wintering, or calving area that contained study animals from the start of the breeding season in the spring of 2001 until June 30, 2002. Researchers continued air monitoring in a subset of herds to the end of the study in fall 2002. Each sampling device was exposed for 1 month and then shipped to the laboratory for analysis. New samplers were installed and the shelters relocated, as necessary, to follow the movements of herd-management groups between pastures. Researchers linked the results of the air-monitoring analysis to individual animals for the relevant month. For the 205 herds examined at pregnancy testing in 2001, monthly mean exposures on the basis of all available data were as follows: sulfur dioxide, geometric mean (GM)=0.5 ppb, geometric standard deviation (GSD)=2.2; hydrogen sulfide, GM=0.14 ppb, GSD=2.3; benzene, GM=0.247 microg/m3, GSD=2.5; and toluene, GM=0.236 microg/m3, GSD=2.7. Benzene and toluene were surrogates for volatile organic compound exposure. In addition to passive measurements of air quality, researchers obtained data from provincial regulatory agencies on the density of oil and gas field facilities and on flaring and venting from the surrounding facilities. They developed the data into additional measures of exposure that were linked to each animal at each location for each month of the study.

    Emergent discourses of social responsibility and accountability have in part fuelled the expansion of distributed medical education (DME). In addition to its potential for redressing physician maldistribution, DME has conferred multiple unexpected educational benefits. In several countries, its recent rise has occurred around the boundaries of traditional medical education practices. Canada has been no exception, with DME proliferating against a backdrop of its longstanding central node, the clinical teaching unit (CTU). The CTU first appeared just over 50 years ago with its position in Canadian health care largely taken-for-granted. Given the increasing prominence of DME, however, it is timely to reconsider what the place of tertiary centre-based practices such as the CTU might be in shifting medical education systems. From a genealogical perspective, it becomes clear that the CTU did not just "happen". Rather, its creation was made possible by multiple interrelated cultural, social, and political changes in Canadian society that, while subtle, are powerfully influential. Making them visible offers a better opportunity to harmonize the benefits of longstanding entities such as the CTU with novel practices such as DME. In so doing, the medical education field may sidestep the pitfalls of investing significant resources that may only produce superficial changes while unwittingly obstructing deeper transformations and improvements. Although this work is refracted through a Canadian prism, reconceptualizing the overall design of medical education systems to take advantage of both tradition and innovation is a persistent challenge across the international spectrum, resistant to tests of time and constraints of context.

  10. Petrophysical approach for S-wave velocity prediction based on brittleness index and total organic carbon of shale gas reservoir: A case study from Horn River Basin, Canada

    When finding the "sweet spot" of a shale gas reservoir, it is essential to estimate the brittleness index (BI) and total organic carbon (TOC) of the formation. Particularly, the BI is one of the key factors in determining the crack propagation and crushing efficiency for hydraulic fracturing. There are several methods for estimating the BI of a formation, but most of them are empirical equations that are specific to particular rock types. We estimated the mineralogical BI based on elemental capture spectroscopy (ECS) log and elastic BI based on well log data, and we propose a new method for predicting S-wave velocity (VS) using mineralogical BI and elastic BI. The TOC is related to the gas content of shale gas reservoirs. Since it is difficult to perform core analysis for all intervals of shale gas reservoirs, we make empirical equations for the Horn River Basin, Canada, as well as TOC log using a linear relation between core-tested TOC and well log data. In addition, two empirical equations have been suggested for VS prediction based on density and gamma ray log used for TOC analysis. By applying the empirical equations proposed from the perspective of BI and TOC to another well log data and then comparing predicted VS log with real VS log, the validity of empirical equations suggested in this paper has been tested.

  11. The Emergence of Flood Insurance in Canada: Navigating Institutional Uncertainty.

    Science.gov (United States)

    Thistlethwaite, Jason

    2016-08-11

    Flood insurance has remained unavailable in Canada based on an assessment that it lacks economic viability. In response to Canada's costliest flood event to date in 2013, the Canadian insurance industry has started to develop a framework to expand existing property insurance to cover flood damage. Research on flood insurance has overlooked why and how insurance systems transition to expand insurance coverage without evidence of economic viability. This article will address this gap through a case study on the emergence of flood insurance in Canada, and the approach to its expansion. Between 2013 and 2016, insurance industry officials representing over 60% of premiums collected in Canada were interviewed. These interviews revealed that flood insurance is being expanded in response to institutional pressure, specifically external stakeholder expectations that the insurance industry will adopt a stronger role in managing flood risk through coverage of flood damage. Further evidence of this finding is explored by assessing the emergence of a unique flood insurance model that involves a risk-adjusted and optional product along with an expansion of government policy supporting flood risk mitigation. This approach attempts to balance industry concerns about economic viability with institutional pressure to reduce flood risk through insurance. This analysis builds on existing research by providing the first scholarly analysis of flood insurance in Canada, important "empirical" teeth to existing conceptual analysis on the availability of flood insurance, and the influence of institutional factors on risk analysis within the insurance sector.

    2014-06-01

    Full Text Available In this article, the educational attainment of Indigenous peoples of working age (25 to 64 years in Canada is examined. This diverse population has typically had lower educational levels than the general population in Canada. Results indicate that, while on the positive side there are a greater number of highly educated Indigenous peoples, there is also a continuing gap between Indigenous and non-Indigenous peoples. Data also indicate that the proportion with less than high school education declined, which corresponds with a rise of those with a PSE; the reverse was true in 1996. Despite these gains, however, the large and increasing absolute numbers of those without a high school education is alarming. There are intra-Indigenous differences: First Nations with Indian Status and the Inuit are not doing as well as non-Status and Métis peoples. Comparisons between the Indigenous and non-Indigenous populations reveal that the documented gap in post-secondary educational attainment is at best stagnant. Out of the data analysis, and based on the history of educational policy, we comment on the current reform proposed by the Government of Canada, announced in February of 2014, and propose several policy recommendations to move educational attainment forward.

    Green buildings use design and construction practices that reduce or eliminate the negative impact of buildings on the environment and their occupants. This paper discusses the aims of the Green Building Council and Leadership in Energy and Environmental Design (LEED), and the current contexts in which both organizations operate in the Canadian construction industry. Some of the reasons to use green building practices were discussed, including moral obligations, compliance and the opportunity for increased revenue and profits. LEED informs purchasing decisions, and its certification process signals environmental credentials about the public sector to voters, linking well to policy instruments. A list of projects and accredited buildings was provided, as well as a forecast for future projects and market shares. A comprehensive list of adaptations to Canadian building codes, standards and regulations was provided, with reference to site selection, water efficiency, energy and atmosphere, materials and resources, and indoor environmental quality. Some of the challenges facing both organizations include the existence of other rating systems already extant in Canada, partnership with federal government, the size of non-residential buildings in Canada, and residential market challenges. Case studies of projects in Canada and internationally were provided, with an overview of construction techniques and sustainable development programs. tabs., figs.

    In Canada, suicide has transitioned from being a criminal activity with much associated stigma, to being a public health concern that needs to be managed by governments and clinicians in a culturally sensitive manner. In Canada and worldwide, the social attitudes toward and legal interpretation of suicide have been dynamic. Much has been proposed in the development of suicide policy in Canada, however Canada is unique in that it remains one of the only industrialized countries without a national suicide prevention strategy. The current article provides a critical review of the history of suicide in Canada, as well as an appraisal of Canadian suicide prevention policies and key government and political milestones that have impacted suicide policy. Current activity regarding a national suicide prevention strategy in Canada is discussed, as well as potential options for clinician involvement.

  20. Placebo Trends across the Border: US versus Canada.

    Directory of Open Access Journals (Sweden)

    Cory S Harris

    Full Text Available Physicians around the world report to using placebos in a variety of situations and with varying degrees of frequency. Inconsistent methodologies, however, complicate interpretation and prevent direct comparisons across studies. While US- and Canada-based physicians share similar professional standards, Canada harbours a less-litigious universal healthcare model with no formal placebo-related policy-factors that may impact how physicians view and use placebos.To compare American and Canadian data, we circulated an online survey to academic physicians practicing in Canada, collected anonymous responses, and extracted those of internists and rheumatologists for comparison to US data obtained through parallel methodologies.Whereas our data show overall concordance across the border-from definitions to ethical limitations and therapeutic potential-differences between American- and Canadian-based placebo practices merit acknowledgement. For example, compared to 45%-80% among US-based respondents, only 23±7% of Canada-based respondents reported using placebos in clinical practice.

Placebo interventions including unwarranted vitamins and herbal supplements (impure placebos as well as sugar pills and saline injections (pure placebos appear more common in Canada, where more doctors described placebos as "placebos" (rather than "medications" and used them as a "diagnostic" tool (rather than a means of placating patient demands for treatment.Cross-border variation in the use of clinical placebos appears minor despite substantial differences in health care delivery system, malpractice climate, and placebo-related policy. The prevalence of impure placebos in both Canadian and US clinics raises ethical and practical questions currently unaddressed by policy and warranting investigation.

    Full Text Available Under Canada's four-year, $136 million Family Violence Initiative, the federal government is calling upon all Canadians to work in partnerships towards the elimination of family violence - child abuse, violence against women, and elder (senior abuse. Family violence is a complex problem and requires the efforts of all Canadians to resolve it. One of the key themes of the Initiative - a multidisciplinary approach to the problem of family violence - is reflected in the selection and development of projects. Activities funded by the seven federal departments and agencies involved in the Initiative emphasize partnerships with the professional, voluntary, corporate, non-government and government sectors.

    Specialization is a pervasive movement in medicine. How specialties develop is a complex phenomenon and does not depend solely on the growth of knowledge. The history of geriatrics in Canada is presented as an example of specialization in our country. The gestation period extended over decades. Practitioners moved from partial specialization to a full-time practice in the care of older patients. Opposition to the emerging specialty was mounted by established fields of practice. The choices made by the leaders of Canadian geriatrics molded the evolution of the specialty and have contributed to its precarious status at the present time.

    Campylobacter species, particularly thermophilic campylobacters, have emerged as a leading cause of human foodborne gastroenteritis worldwide, with Campylobacter jejuni, Campylobacter coli, and Campylobacter lari responsible for the majority of human infections. Although most cases of campylobacteriosis are self-limiting, campylobacteriosis represents a significant public health burden. Human illness caused by infection with campylobacters has been reported across Canada since the early 1970s. Many studies have shown that dietary sources, including food, particularly raw poultry and other meat products, raw milk, and contaminated water, have contributed to outbreaks of campylobacteriosis in Canada. Campylobacter spp. have also been detected in a wide range of animal and environmental sources, including water, in Canada. The purpose of this article is to review (i) the prevalence of Campylobacter spp. in animals, food, and the environment, and (ii) the relevant testing programs in Canada with a focus on the potential links between campylobacters and human health in Canada.

    This study examined the relationships between academic motivation-intrinsic motivation, extrinsic motivation, amotivation-and mathematics achievement among 363 Indian adolescents in India and 355 Indian immigrant adolescents in Canada. Results of hierarchical multiple regression analyses showed that intrinsic motivation, extrinsic motivation, and amotivation were not statistically significantly related to mathematics achievement among Indian adolescents in India. In contrast, both intrinsic motivation and extrinsic motivation were statistically significantly related to mathematics achievement among Indian immigrant adolescents in Canada. While intrinsic motivation was a statistically significant positive predictor of mathematics achievement among Indian immigrant adolescents in Canada, extrinsic motivation was a statistically significant negative predictor of mathematics achievement among Indian immigrant adolescents in Canada. Amotivation was not statistically significantly related to mathematics achievement among Indian immigrant adolescents in Canada. Implications of the findings for pedagogy and practice are discussed.

    There is little published literature about the outcomes of dental hygiene baccalaureate degree education, particularly in Canada. Since there are various dental hygiene entry-to-practice educational models in Canada, exploring baccalaureate dental hygiene education is becoming an increasingly important subject. The purpose of this study was to explore the personal outcomes and dental hygiene practice outcomes of dental hygiene degree-completion education in Canada from the perspectives of diploma dental hygienists who have continued their education to the bachelor's degree level. This study employed a qualitative phenomenological design, using a maximum variation purposeful sampling strategy. Data generation occurred with sixteen dental hygienists across Canada through individual semistructured interviews. Interviews were audiorecorded, transcribed verbatim, and coded for data analysis, involving pattern recognition and thematic development. Themes that emerged included changes in self-perception, values, and knowledge base. Changes in self-perception were reflected in a reported increase in self-confidence and perceived credibility. Changes in values included a greater appreciation for lifelong learning. Advancements in knowledge strengthened the development of specific abilities that ultimately influenced participants' dental hygiene practice. These abilities included an increased ability to think critically, to make evidence-based decisions, and to provide more comprehensive care. Participants also commented on having more career opportunities available to them outside of the private clinical practice setting. These results reveal important insights into the impact of earning a dental hygiene baccalaureate degree on oneself and one's dental hygiene practice.

  16. Spatial and seasonal variations in evapotranspiration over Canada's landmass

    Full Text Available A 30 yr (1979–2008 dataset of actual evapotranspiration (ET at 1 km resolution was generated over Canada's landmass by integrating remote sensing land surface data and gridded climate data using the EALCO model run at 30 min time step. This long-term high resolution dataset was used to characterize the spatiotemporal variations in ET across Canada. The results show that annual ET varied from 600 mm yr−1 over several regions in the south to less than 100 mm yr−1 in the northern arctic. Nationally, ET in summer (i.e., June to August comprised 65% of the annual total amount. ET in the cold season remained mostly below 10 mm month−1 over the country. Negative monthly ET was obtained over the arctic region in winter, indicating EALCO simulated a larger amount of condensation than ET. Overall, the mean ET over the entire Canadian landmass for the 30 yr was 239 mm yr−1, or 44% of its corresponding precipitation. Comparisons of available ET studies in Canada revealed large uncertainties in ET estimates associated with using different approaches. The scarcity of ET measurements for the diverse ecosystems in Canada remains a significant challenge for reducing the uncertainties; this gap needs to be addressed in future studies to improve capabilities in climate/weather modelling and water resource management.

    Scientific certainty regarding environmental toxin-related etiologies of breast cancer, particularly among women with genetic polymorphisms in estrogen metabolizing enzymes, is lacking. Fungicides have been recognized for their carcinogenic potential, yet there is a paucity of epidemiological studies examining the health risks of these agents. The association between agricultural fungicide exposure and breast cancer risk was examined in a secondary analysis of a province-wide breast cancer case-control study in Prince Edward Island (PEI) Canada. Specific objectives were: (1) to derive and examine the level of association between estimated fungicide exposures, and breast cancer risk among women in PEI; and (2) to assess the potential for gene-environment interactions between fungicide exposure and a CYP1A1 polymorphism in cases versus controls. After 1:3 matching of 207 cases to 621 controls by age, family history of breast cancer and menopausal status, fungicide exposure was not significantly associated with an increased risk of breast cancer (OR = 0.74; 95% CI: 0.46-1.17). Moreover, no statistically significant interactions between fungicide exposure and CYP1A1*2A were observed. Gene-environment interactions were identified. Though interpretations of findings are challenged by uncertainty of exposure assignment and small sample sizes, this study does provide grounds for further research.

    Full Text Available Abstract Background To study and update the provincial incidence of type 1 diabetes mellitus (T1DM in Newfoundland and Labrador (NL, a province of Canada with a very high incidence previously reported in 2006, and one of the highest incidences reported worldwide. This is a retrospective time trend study of the incidence of T1DM, in children aged 0–14 years from 1987–2010 inclusive. Findings Over the study period 931 children aged 0–14 years were diagnosed with T1DM. The incidence of T1DM in this population over the period 1987 – 2010 inclusive was 37.7 per 100,000 per year (95% CI 35. 3, 40.2 The incidence from 2007–2010 was 49.9 per 100,000 per year (95% CI 42.2, 57.6. The incidence over this 24 year period increased by a factor of 1.03 per 100,000 per year. Conclusion NL has one of the highest incidences of T1DM reported worldwide. Potential reasons for the very high incidence could be related to the unique genetic background of the population, northern latitude and vitamin D insufficiency, low breastfeeding rates, and high rates of cesarean section.

    Full Text Available Abstract Background Respondent-driven sampling (RDS is an increasingly used peer chain-recruitment method to sample “hard-to-reach” populations for whom there are no reliable sampling frames. Implementation success of RDS varies; one potential negative factor being the number of seeds used. Methods We conducted a sensitivity analysis on estimates produced using data from an RDS study of gay, bisexual and other men who have sex with men (GBMSM aged ≥16 years living in Vancouver, Canada. Participants completed a questionnaire on demographics, sexual behavior and substance use. For analysis, we used increasing seed exclusion criteria, starting with all participants and subsequently removing unproductive seeds, chains of ≤1 recruitment waves, and chains of ≤2 recruitment waves. We calculated estimates for three different outcomes (HIV serostatus, condomless anal intercourse with HIV discordant/unknown status partner, and injecting drugs using three different RDS weighting procedures: RDS-I, RDS-II, and RDS-SS. We also assessed seed dependence with bottleneck analyses and convergence plots. Statistical differences between RDS estimators were assessed through simulation analysis. Results Overall, 719 participants were recruited, which included 119 seeds and a maximum of 16 recruitment waves (mean chain length = 1.7. The sample of >0 recruitment waves removed unproductive seeds (n = 50/119, 42.0%, resulting in 69 chains (mean length = 3.0. The sample of >1 recruitment waves removed 125 seeds or recruits (17.4% of overall sample, resulting in 37 chains (mean length = 4.8. The final sample of >2 recruitment waves removed a further 182 seeds or recruits (25.3% of overall sample, resulting in 25 chains (mean length = 6.1. Convergence plots and bottleneck analyses of condomless anal intercourse with HIV discordant/unknown status partner and injecting drugs outcomes were satisfactory. For these two outcomes, regardless of seed

    2009-10-01

    Full Text Available This article studies the historical representation of the two main national communities in Canada; that is, the English-Canadian and the French-Canadian.Throughout the history of the English Canadian community, one cansee an ambitious national project. The national construction of Canada suggests the existence of a neutral model of government but, when looking at this carefully, it is possible to see something quite different. English-speaking historians from Canada have normally introduced the concept of a unitary federalism as the most perfect form of the Canadian integration project. This integrating federalism, that does not lead to emancipation, stems from thecentralist views of John Macdonald, one of the fathers of Canadian federalism. This approach has been kept for over 140 years of common history and, to this date, continues to be one of the main obstacles for minority nations within Canada. To strengthen their thesis, the authors base their work on an extensive analysis exploring the three big strategies used by the central government to assert its authority on the member States of the Canadian Federation in the long term: using the judicial power, centralizing powers andglobalization. The strategies used have varied depending on the economic scenario, political leaders and the political power relations regarding the links between the Federation and the provinces.

    Parks and gardens are poly-functional elements of great importance in urban areas, and can be used for optimization of physical and social components in these areas. This study aimed to investigate alteration of soil properties with land usages within urban park and with area size of park. Ten parks differed by size (2 - 50 acres) were chosen, in random, in Tel-Aviv- Jaffa city. Soil was sampled in four microenvironments ((lawn, path, picnic and peripheral area (unorganized area) of each the park)), in three points and three depth (0-2, 5-10 and 10-20 cm). Penetration depth was measured in all point of sampling. For each soil sample electrical conductivity and organic matter content were determined. Averages of penetration depth drastically increased from the most disturbed microenvironments (path and picnic) to the less disturbed ones (lawn and peripheral). The maximal heterogeneity (by variances and percentiles) of penetration depth was found in the peripheral area. In this area, penetration depth increased with increasing park size, i.e., from 2.6 cm to 3.7 cm in the small and large parks, respectively. Averages of organic matter content and electrical conductivity decreased with soil depth in all microenvironments and increased with decreasing disturbance of microenvironments. Maximal heterogeneity for both of these properties was found in the picnic area. Increase of park size was accompanied by increasing of organic matter content in the upper depth in the peripheral area, i.e., from 2.4% in the small parks to 4.5% in the large ones. In all microenvironments the increasing of averages of all studied soil properties was accompanied by increasing heterogeneity, i.e., variances and upper percentiles. The increase in the heterogeneity of the studied soil properties is attributed to improved ecological soil status in the peripheral area, on the one hand, and to the high anthropogenic pressure in the picnic area, on the other. This means that the urban park offers

  7. Canada's population: growth and dualism.

    Science.gov (United States)

    Beaujot, R P

    1978-04-01

    In Canada the current 1.3% population growth rate is causing some concern. Those concerned argue that such a rate of growth in combination with high levels of consumption could jeopardize the country's resource base and its comfortable style of living. Many Canadians are questioning high levels of immigration, for now that the fertility level is below replacement level, net immigration contributes substantially to population growth (over 1/3 in 1976). The growing proportion of non-Europeans among recent immigrants is causing resentment, and, in a tight job market, immigrants are regarded as threats to the World War 2 baby boom cohort who are now at working ages. The baby boom generation also puts stress on housing and health services, and it will increase the need for pension checks as it ages. Although French fertility is no longer high and immigration is no longer dominated by the British, the French group's 200-year struggle to preserve its identity continues on in the current effort of the Quebec government to enforce the use of French language by law within that province. Geography and climate dictate another demographic fact that divides the country and pervades its history. In addition to intense regionalism, uneven population distribution is responsible for 2 other concerns: the rapid growth of several already large cities and depopulation of many small communities. Focus in this discussion is on Canada's population growth in the past and as projected for the future, historical and current fertility, mortality and immigration trends, the search for a new immigration policy, the impact of the baby boom generation on the population's age structure and the problems this creates, and recent shifts in population distribution and in the country's ethnic and linguistic makeup. The population policy proposals evolved thus far involve to a great extent the use of immigration as a lever for achieving given population objectives.

  8. Comparing the effectiveness of copper intrauterine devices available in Canada. Is FlexiT non-inferior to NovaT when inserted immediately after first-trimester abortion? Study protocol for a randomized controlled trial

    2012-08-01

    Full Text Available Abstract Background We describe the rationale and protocol for a randomized noninferiority controlled trial (RCT to determine if the Flexi-T380(+ copper intrauterine contraceptive device (IUD is comparable in terms of effectiveness and expulsion rates to the most common Canadian IUD currently in use, NovaT-200, when placed immediately after a first-trimester abortion. Methods/Design Consenting women choosing to use an IUD after an abortion for a pregnancy of less than 12 weeks of gestation will be randomized to device-type groups to receive immediate post-abortion placement of either a Flexi-T380(+ IUD, a device for which no current evidence on expulsion or effectiveness rates is available, or the Nova-T200 IUD, the only other brand of copper IUD available in Canada at the time of study initiation. The primary outcome measure is IUD expulsion rate at 1 year. Secondary outcomes include: pregnancy rate, method continuation rate, complication rates (infection, perforation, and satisfaction with contraceptive method. A non-intervention group of consenting women choosing a range of other post-abortion contraception methods, including no contraception, will be included for comparison of secondary outcomes. Web-based contraception satisfaction questionnaires, clinical records, and government-linked health administrative databases will be used to assess primary and secondary outcomes. Discussion The RCT design, combined with access to clinical records at all provincial abortion clinics, and to information in provincial single-payer linked administrative health databases, birth registry, and hospital records, offers a unique opportunity to determine if a novel IUD has a comparable expulsion rate to that of the current standard IUD in Canada, in addition to the first opportunity to determine pregnancy rate and method satisfaction at 1 year post-abortion for women choosing a range of post-abortion contraceptive options. We highlight considerations of

  20. Emerging Churches in Post-Christian Canada

    Directory of Open Access Journals (Sweden)

    Steven Studebaker

    2012-09-01

    Full Text Available The traditional mainline and evangelical churches in Canada, as in most western countries, are either in decline or static. Taken as a measure of the future, the prospects for Christianity in Canada, and more broadly the West, are bleak. Post-Christian Canada, however, contains thriving alternative and innovative forms of church, often called ‘emerging’ churches. They take many forms of expression, but share common theological convictions. Based on site research and personal interviews, this article describes the various types and contexts of these churches in Canada. It then highlights three of their central theological characteristics. First, rejecting the ‘culture wars’ social involvement of Christendom churches, they embrace practices and initiatives that transform their local communities. Second, they embrace an incarnational and contextual understanding of Christian life and ministry. Eschewing mega-church franchise models, they endeavor to shape their ministry to the their local communities. Third, they adopt a comprehensive rather than compartmental spirituality.

    1999-07-01

    Bombardier Inc. of Montreal, Canada has installed over 15,000 m{sup 2} of unglazed solar air collectors at its various manufacturing plants in Quebec. The solar collectors decrease operating expenses and significantly improve indoor air quality. Bombardier's engineers compared the cost of this system with other methods of recladding and improving ventilation and found the costs to be the same. With no extra costs for free solar heating, the system has an immediate payback, along with other benefits of improved air quality and attractive architecturally designed walls that utilize solar energy. Bombardier's first solar heating installation at their Sea Doo manufacturing plant has a solar wall area of 740 m{sup 2}. The heat-absorbing surface area is 611 m{sup 2} of a custom dark olive-green colour, with the balance being the white canopy plenum along the top and vertical dividers. The entire surface of the solar panel is separated into six sections with one fan per section. Wall-mounted ventilation fans were installed to bring in a total of 71,400 m{sup 3}/h of heated ventilation air. Monitored solar and destratification savings for the year 1993-94 were CA $33,000 (ECU 20,440) based on energy savings of 894,000 kWh. (author)

  11. Increasing turbine vendor competition in Canada

    Energy Technology Data Exchange (ETDEWEB)

    Magee, J.T. [Emerging Energy Research, Cambridge, MA (United States)

    2008-07-01

    An overview of the wind turbine market in Canada was presented. Canada is now experiencing increased turbine vendor competition. Trends in wind turbine OEM market shares in Canada have increased from 10 per cent in 2000 to over 70 per cent in 2007. Several major companies in Canada have signed large-scale orders for delivery in 2010. It is expected that future wind turbine demands in all areas of Canada will increase. However, projections for Canadian wind growth demonstrate the difficulties provinces are now facing in trying to attract manufacturing investment away from the United States. Growth in wind turbine investment is in the process of creating a more robust North American wind turbine generator chain. However, the majority of new facilities are located in the United States. It is not known if Quebec's wind turbine generators will be viable outside of fulfilling Hydro-Quebec's tendering process. Canada's wind industry must consider equipment transport costs as well as a shortage of operating and maintenance service infrastructure. It was concluded that growth in the United States is expected to have a positive impact on Canadian wind energy customers. tabs., figs.

  12. Diabetes in pregnancy among indigenous women in Australia, Canada, New Zealand, and the United States: a method for systematic review of studies with different designs

    Directory of Open Access Journals (Sweden)

    2011-12-01

    Full Text Available Abstract Background Diabetes in pregnancy, which includes gestational diabetes mellitus (GDM and type 2 diabetes mellitus (T2DM, is associated with poor outcomes for both mother and infant during pregnancy, at birth and in the longer term. Recent international guidelines recommend changes to the current GDM screening criteria. While some controversy remains, there appears to be consensus that women at high risk of T2DM, including indigenous women, should be offered screening for GDM early in pregnancy, rather than waiting until 24-28 weeks as is current practice. A range of criteria should be considered before changing screening practice in a population sub-group, including: prevalence, current practice, acceptability and whether adequate treatment pathways and follow-up systems are available. There are also specific issues related to screening in pregnancy and indigenous populations. The evidence that these criteria are met for indigenous populations is yet to be reported. A range of study designs can be considered to generate relevant evidence for these issues, including epidemiological, observational, qualitative, and intervention studies, which are not usually included within a single systematic review. The aim of this paper is to describe the methods we used to systematically review studies of different designs and present the evidence in a pragmatic format for policy discussion. Methods/Design The inclusion criteria will be broad to ensure inclusion of the critical perspectives of indigenous women. Abstracts of the search results will be reviewed by two persons; the full texts of all potentially eligible papers will be reviewed by one person, and 10% will be checked by a second person for validation. Data extraction will be standardised, using existing tools to identify risks for bias in intervention, measurement, qualitative studies and reviews; and adapting criteria for appraising risk for bias in descriptive studies.

    While many jurisdictions in Canada use the Canadian Dam Association (CDA) dam safety guidelines, their applicability to the safety of mining dams is limited. Mining dams are some of the largest containment structures in the world, and impound millions of cubic meters of mine process residues in both solid and liquid form. This study presented a review of dam safety regulatory frameworks for mining dams located in various countries. The aim of the study was to compare the Canadian framework with various dam safety legislations in order to evaluate Canada's current status and recommend best practices in dam safety regulations. The study reviewed incremental consequence classifications; best practices in operation, surveillance and maintenance manuals and procedures; emergency preparedness plans; and dam safety inspections. The study showed that Canada has limited documentation regulating the safe management of tailings facilities, and does not have an all-encompassing national guideline for mining dams. It was concluded that an incremental consequence classification (ICC) system should be developed specifically for mining dams. 12 refs.

    Introduction Current studies of depression among people living with HIV focus on describing its point prevalence. Given the fluctuating nature of depression and its profound impacts on clinical and quality-of-life outcomes, this study aimed to examine the prevalence, recurrence and incidence of current depressive symptoms and its underlying catalysts longitudinally and systematically among these individuals. Methods We conducted a prospective cohort study between October 1, 2007 and December 31, 2012 using longitudinal linked data sources. Current depressive symptoms was identified using the Centre for Epidemiologic Studies Depression Scale or the Kessler Psychological Distress Scale, first at baseline and again during follow-up interviews. Multivariable regressions were used to characterize the three outcomes. Results Of the 3,816 HIV-positive participants, the point prevalence of depressive symptoms was estimated at 28%. Of the 957 participants who were identified with depressive symptoms at baseline and who had at least two years of follow-up, 43% had a recurrent episode. The cumulative incidence among 1,745 previously depressive symptoms free participants (at or prior to baseline) was 14%. During the five-year follow-up, our multivariable models showed that participants with greater risk of recurrent cases were more likely to feel worried about their housing situation. Participants at risk of developing incident cases were also likely to be younger, gay or bisexual, and unable to afford housing-related expenses. Conclusions Depressive symptoms are prevalent and likely to recur among people living with HIV. Our results support the direction of Ontario’s HIV/AIDS Strategy to 2026, which addresses medical concerns associated with HIV (such as depression) and the social drivers of health in order to enhance the overall well-being of people living with or at risk of HIV. Our findings reinforce the importance of providing effective mental health care and

    2010-04-01

    Full Text Available Objective: To analyze the social determinants of pulmonary tuberculosis in the families of migrant laborers registered in the Seasonal Agricultural Workers Program (SAWP and residing in Guadalupe Zaragoza Tlahuapan, Puebla, México. Methods: An exploratory cross-sectional study of the interaction between migration, social determinants, and pulmonary tuberculosis. Results: In this poor and patriarchal community, the SAWP offers financial opportunities for the men of Guadalupe Zaragoza. The remittances of these migrant workers have enabled their families to live in adequate housing, but their health situation is still vulnerable. Only half of the families have access to public health services or the special health programs for migrant worker families. 13% of migrant family members were infected with pulmonary tuberculosis as measured by the Quantiferon-TB test. The female partners of migrants typically do not study past elementary school, become housewives with no pay, are forced to take on added work in the household, and experience subjective symptoms of stress and fatigue. The children of Guadalupe Zaragoza are also vulnerable; the number of children in this community who can regularly attend school is below the national average because many children have to work. These families end up paying more for education, housing, and health services than the average Mexican family. Conclusions: In the families of SAWP migrant workers, the prevalence of latent pulmonary tuberculosis was found to be lower than the national average based on studies using the tuberculin test; this may be due to the greater specificity of the Quantiferon-TB Gold test. There is a significant risk of reactivation tuberculosis in these families due to the inequity in the social determinants of health.

    Full Text Available Objectives: The purpose of this mixed methods study was to examine the quality of work life of registered nurses working in obstetrics at 4 hospitals in northeastern Ontario and explore demographic and occupational factors related to nurses’ quality of work life (QWL. Material and Methods: A stratified random sample of registered nurses (N = 111 selected from the 138 eligible registered nurses (80.4% of staff in the labor, delivery, recovery, and postpartum areas at the 4 hospitals participated. Logistic regression analyses were used to consider QWL in relation to the following: 1 demographic factors, and 2 stress, employment status and educational attainment. Results: In the logistic regression model, the odds of a higher quality of work life for nurses who were cross trained (nurses who can work across all areas of obstetrical care were estimated to be 3.82 (odds ratio = 3.82, 95% confidence interval: 1.01–14.5 times the odds of a higher quality of work life for nurses who were not cross trained. Conclusions: This study highlights a relationship between quality of work life and associated factors including location of cross-training among obstetrical nurses in northeastern Ontario. These findings are supported by the qualitative interviews that examine in depth their relationship to QWL. Given the limited number of employment opportunities in the rural and remote regions, it is paramount that employers and employees work closely together in creating positive environments that promote nurses’ QWL.

    Epidemiological studies suggest that fish consumption may be a protective factor against the development of prostate cancer. We investigated the association between prostate cancer risk and fresh and preserved fish consumption among participants of a population-based case-control study (1,534 cases, 1,607 controls). Fish intake was measured using a dietary questionnaire that collected both frequency of consumption of a given portion size. Logistic regression analysis demonstrated an inverse association between preserved fish and prostate cancer risk for all levels of consumption, but reductions only reached statistical significance for the category of 1 to 3 servings of preserved fish per month (odds ratio = 0.78, confidence interval = 0.64-0.95). Consumption of any fat or energy from preserved fish was also associated with reduced risk. There was no suggestion of reduced prostate cancer risk with consumption of fresh and canned fish. Our results suggest that consumption of preserved fish may reduce the risk of developing prostate cancer.

    This study provided a qualitative assessment of the potential impacts and risks associated with the development of liquefied natural gas (LNG) terminals on the United States side of Pasamaquoddy Bay. The report included an assessment of environmental impacts, marine and navigational safety impacts, and socio-economic impacts as a result of the terminal. The report also investigated the potential impacts on coastal ecosystems and wetlands, as well as potential impacts on land-based flora and fauna. Impacts from marine traffic through Canadian waters were considered. Three worst-case risk scenarios were used as the basis for determining potential environmental and socio-economic impacts. Potential effects and policy considerations associated with the construction of LNG terminals in the region were discussed. The study considered 3 project areas: the Quoddy Bay LNG project; the Downeast LNG project; and the Calais LNG project. The consequences of vapour clouds and pool fires were considered, as well as the overall hazards associated with a large LNG spill. Evaluation scenarios were considered for leaks and minor releases. Transportation and navigational issues included ship specifications, traffic movements and route analyses. Issues related to whales and hatcheries were considered. Emergency preparedness and response plans were included. An assessment of cumulative risks in the region was also provided. 182 refs., 65 tabs., 23 figs.

    2011-09-01

    Full Text Available Objective: Cancer has been recognized to have environmental origin, but occupational cancer risk studies have not been fully documented. The objective of this paper was to identify occupations and industries with elevated colon cancer risk based on lifetime occupational histories collected from 15,463 incident cancer cases. Method: A group matched case-control design was used. All cases were diagnosed with histologically proven colon cancers, with cancer controls being all other cancer sites, excluding rectum, lung and unknown primary, diagnosed at the same period of time from the British Columbia Cancer Registry. Data analyses were done on all 597 Canadian standard occupation titles and 1,104 standard industry titles using conditional logistic regression for matched data sets and the likelihood ratio test. Results: Excess colon cancer risks was observed in a number of occupations and industries, particularly those with low physical activity and those involving exposure to asbestos, wood dusts, engine exhaust and diesel engine emissions, and ammonia. Discussion: The results of our study are in line with those from the literature and further suggest that exposure to wood dusts and to ammonia may carry an increased occupational risk of colon cancer.

    The goal of the study is to examine how location (nationally, compared to Canadian regions) is related to indicators of a hostile school environment for sexual minority youth, particularly when physical abuse is used as the outcome variable. Data representing 5,766 Canadian students were analyzed using bivariate and multivariate techniques. Results from the multivariate analyses showed that non-physical abuse was the most significant predictor of homophobically based physical abuse, for both LGBQ and non-LGBQ students. Findings reiterate the importance of considering the progression of harmful events as an escalation of violence as well as the need to view homophobic bullying as having a significant impact on all students. Finally, while the presence of homophobia is prevalent across all Canadian regions, there are, nevertheless, many regional differences, which could be used to inform region-specific action plans.

    2016-06-01

    Urban renewal often drives away the original residents, replacing them with higher income residents who can afford the new spaces, leading to gentrification. Urban renewal that takes place over many years can create uncertainties for retailers and residents, exacerbating the gentrification process. This qualitative study explored how the urban renewal process in a multi-cultural social housing neighborhood in Toronto (Regent Park) affected the small ethnic retail grocery stores (SERGS) that supplied ethnic foods and items to the ethnic populations living there. Interviews were conducted with ten SERGS store owners/managers and 16 ethnic residents who lived in Regent Park before renewal and were displaced, or who were displaced and returned. The SERGS stated that they provided culturally familiar items and offered a social credit scheme that recognized existing social relationships and allowed low-income residents to afford food and other amenities in a dignified manner and pay later, without penalty or interest. At the same time, the SERGS were unsupported during the renewal, were excluded from the civic planning processes, could not compete for space in the new buildings, and experienced declining sales and loss of business. The residents stated that the SERGS were trusted, provided a valued cultural social spaces for ethnic identity formation, and ethnic food security but they faced many uncertainties about the role of SERGS in a renewed neighborhood. Based on this study, it is recommended that ethnic retailers be recognized for the role they play in formulating ethnic identities and food security in mixed-use mixed-income communities and that they be included in planning processes during urban renewal. Such recognition may enable more former residents to return and lessen the gentrification.

    The Petroleum Technology Alliance of Canada's low carbon futures study was discussed along with a study in which scenarios were developed for three resources, notably bitumen in carbonate reservoirs; conventional heavy oil; and warm water geothermal energy from operating oil wells. The presentation provided an overview of geothermal systems including hot dry rock; dry steam resources; hot water resources; warm water resources; and low temperature systems. A warm water geothermal study for the Western Canada Sedimentary Basin (WCSB) was also presented. Although high quality geothermal energy sources are rare in Canada, there are large warm water geothermal reservoirs, ranging in temperature from 50 to 180 degrees C in the WCSB. This presentation focused on the potential for recovery of the warm water geothermal energy already being brought to surface from the WCSB's oil wells. Several energy approaches were also presented, such as warm geothermal or produced water being used for heating an oil reservoir; using produced mechanical energy for field pumping; and producing renewable electricity from binary plants with propane. Illustrations were also provided for the organic Rankine cycle; low pump geothermal power; and no pump geothermal system. Combined geothermal and oil production were also discussed. Other topics that were presented included industrial cooling; municipal cooling; mined oilsands barriers and tailings; containment of in-situ oilsands; and rural freeze desalination. The report concluded with discussions of the Canadian minerals industry; cold Arctic construction; and ice roads in the North. It was concluded that there is potential for warm water geothermal in existing oilfield operations in Canada. tabs., figs.

    2014-05-01

    The reconstruction of the history of former glacial lakes is commonly based on the study of strandlines that generally consist of boulder ridges, sandy beaches and other near-shore deposits. This approach, however, is limited in some regions where the surficial geology consists of thick accumulation of fine-grained glaciolacustrine sediments that mask most deglacial landforms. This situation is particularly relevant to the study of Lake Ojibway, a large proglacial lake that developed in northern Ontario and Quebec following the retreat of the southern Laurentide ice sheet margin during the last deglaciation. The history of Ojibway lake levels remains poorly known, mainly due to the fact that this lake occupied a deep and featureless basin that favored the sedimentation of thick sequences of rhythmites and prevented the formation of well-developed strandlines. Nonetheless, detailed mapping revealed a complex sequence of discontinuous small-scale cliffs that are scattered over the flat-lying Ojibway clay plain. These terrace-like features range in size from 4 to 7 m in height and can be followed for 10 to 100's of meters. These small-scale geomorphic features are interpreted to represent raised shorelines that were cut into glaciolacustrine sediments by lakeshore erosional processes (i.e., wave action). These so-called wave-cut scarps (WCS) occur at elevations ranging from 3 to 30 m above the present level of Lake Abitibi (267 m), one of the lowest landmarks in the area. Here we evaluate the feasibility of using this type of relict shorelines to constrain the evolution of Ojibway lake levels. For this purpose, a series of WCS were measured along four transects of about 40 km in length in the Lake Abitibi region. The absolute elevation of 154 WCS was determined with a Digital Video Plotter software package using 1:15K air-photos, coupled with precise measurements of control points, which were measured with a high-precision Global Navigation Satellite System tied up to

    Engineered wood products for structural use must meet minimum strength and stiffness criteria. This represents a major challenge for the industry as the mechanical properties of the wood resource are inherently variable. We report on a case study that was conducted in a laminated veneer lumber (LVL) mill in order to test the potential of an acoustic sensor to predict structural properties of the wood resource prior to processing. A population of 266 recently harvested aspen logs were segregated into three sub-populations based on measurements of longitudinal acoustic speed in wood using a hand tool equipped with a resonance-based acoustic sensor. Each of the three sub-populations were peeled into veneer sheets and graded for stiffness with an ultrasonic device. The average ultrasonic propagation time (UPT) of each subpopulation was 418, 440 and 453 microseconds for the green, blue, and red populations, respectively. This resulted in contrasting proportions of structural veneer grades, indicating that the efficiency of the forest value chain could be improved using acoustic sensors. A linear regression analysis also showed that the dynamic modulus of elasticity (MOE) of LVL was strongly related to static MOE (R(2) = 0.83), which suggests that acoustic tools may be used for quality control during the production process.

  13. Crisis of Identity in a Multi-cultural Society: The Case of Muslims in Canada

    Full Text Available A great majority of studies on ethnic identity or ethnic separatism indicate that a minority group dealing with severe deprivation becomes more frustrated, more aggressive, and more demanding of autonomy or separation. However, in a multi-cultural society where the people can live with their both separate and co-existing identities, the minority group usually demands for greater rights within societies, not an exit from them. This is the case of the Muslims in Canada who constitute a tiny minority in the Canadian population. Since Canada is a multicultural country, the Muslims have not demanded any kind of autonomy but have demanded rights to preserve Islamic values, and their own distinct identity as Muslims. In this article some basic questions are raised regarding the Canadian Muslims. When and how did the Muslims arrive in Canada? What types of challenges they are facing? How do they meet these challenges? What is the future of Muslims in Canada?

    The Canadian Perinatal Surveillance System has provided a comprehensive review of maternal mortality and severe maternal morbidity in Canada, and has identified several important limitations to existing national maternal data collection systems, including variability in the detail and quality of mortality data. The Canadian Perinatal Surveillance System report recommended the establishment of an ongoing national review and reporting system, as well as consistency in definitions and classifications of maternal mortality and severe maternal morbidity, in order to enhance surveillance of maternal mortality and severe maternal morbidity. Using review articles and studies that examined maternal mortality in general as opposed to maternal mortality associated with particular management strategies or conditions, maternal mortality and severe morbidity classifications, terminology, and comparative statistics were reviewed and employed to evaluate deficiencies in past and current methods of data collection and to seek solutions to address the need for enhanced and consistent national surveillance of maternal mortality and severe maternal morbidity in Canada.

  16. Recent U.S. Geological Survey Studies in the Tintina Gold Province, Alaska, United States, and Yukon, Canada-Results of a 5-Year Project

    Science.gov (United States)

    Gough, Larry P.; Day, Warren C.

    2010-01-01

    This report presents summary papers of work conducted between 2002 and 2007 under a 5-year project effort funded by the U.S. Geological Survey Mineral Resources Program, formerly entitled 'Tintina Metallogenic Province: Integrated Studies on Geologic Framework, Mineral Resources, and Environmental Signatures.' As the project progressed, the informal title changed from 'Tintina Metallogenic Province' project to 'Tintina Gold Province' project, the latter being more closely aligned with the terminology used by the mineral industry. As Goldfarb and others explain in the first chapter of this report, the Tintina Gold Province is a convenient term used by the mineral exploration community for a 'region of very varied geology, gold deposit types, and resource potential'. The Tintina Gold Province encompasses roughly 150,000 square kilometers, bounded by the Kaltag-Tintina fault system on the north and the Farewell-Denali fault system on the south. It extends westward in a broad arc, some 200 km wide, from northernmost British Columbia, through the Yukon, through southeastern and central Alaska, to southwestern Alaska. The climate is subarctic and, in Alaska, includes major physiographic delineations and ecoregions such as the Yukon-Tanana Upland, Tanana-Kuskokwim Lowlands, Yukon River Lowlands, and the Kuskokwim Mountains. Although the Tintina Gold Province is historically important for some of the very first placer and lode gold discoveries in northern North America, it has recently seen resurgence in mineral exploration, development, and mining activity. This resurgence is due to both new discoveries (for example, Pogo and Donlin Creek) and to the application of modern extraction methods to previously known, but economically restrictive, low-grade, bulk-tonnage gold resources (for example, Fort Knox, Clear Creek, and Scheelite Dome). In addition, the Tintina Gold Province hosts numerous other mineral deposit types, possessing both high and low sulfide content, which

    The diagnosis of peanut allergy (PA) can be complex especially in children never exposed to peanut or with an uncertain history. The aim of the study is to determine which diagnostic algorithms are used by Canadian allergists in such children. Children 1-17 yrs old never exposed to peanut or with an uncertain history having an allergist-confirmed diagnosis of PA were recruited from the Montreal Children's Hospital (MCH) and allergy advocacy organizations. Data on their clinical history and confirmatory testing were compared to six diagnostic algorithms: I. Skin prick test (SPT) >or=8 mm or specific IgE >or=5 kU/l or positive food challenge (+FC); II. SPT >or=8 or IgE >or=15 or +FC; III. SPT >or=13 or IgE >or=5 or +FC; IV. SPT >or=13 or IgE >or=15 or +FC; V. SPT >or=3 and IgE >or=5 or IgE >or=5 or +FC; VI. SPT >or=3 and IgE >or=15 or IgE >or=15 or +FC. Multivariate logistic regression analysis was used to identify factors associated with the use of each algorithm. Of 497 children recruited, 70% provided full data. The least stringent algorithm, algorithm I, was applied in 81.6% (95% CI, 77-85.6%) of children and the most stringent, algorithm VI, in 42.6% (95% CI, 37.2-48.1%).The factor most associated with the use of all algorithms was diagnosis made at the MCH in those never exposed to peanut. Other factors associated with the use of specific diagnostic algorithms were higher paternal education, longer disease duration, and the presence of hives, asthma, eczema, or other food allergies. Over 18% (95% CI, 14.4-23.0%) of children were diagnosed with PA without fulfilling even the least stringent diagnostic criteria.

    2014-12-01

    This poster describes the results of reconnaissance carried out by the Arctic Institute of North America in summer 2014 in collaboration with USArray and IRIS for deployment of the USArray in northern British Columbia and Yukon Territory, Canada. USArray is a 15-year program to place a dense network of permanent and portable seismographs across the continental United States and parts of Canada. The seismographs record local, regional, and distant (teleseismic) earthquakes. The array records seismic waves that propagate through finer and finer slices of the earth enabling scientists to link structures inherited from earlier stages of continental formation to known and potential geologic hazards (e.g., earthquakes, volcanoes, landslides) (www.usarray.org). USArray deployment in Canada will complement existing Canadian seismic network(s). This project will be particularly significant in the St. Elias region of southwest Yukon, northwest British Columbia, and southeast Alaska as this one of the most seismically active areas and tectonically complex areas in Canada . The deployment will complement ongoing geological mapping carried out by both Yukon Geological Survey, the Geological Survey of Canada and several universities. This reconnaissance work is part of a growing portfolio of research conducted by the Arctic Institute of North America, University of Calgary designed to meet needs for information and enable synthesis and transfer of knowledge for problem solving and decision-making in the north.

  20. Women in academic psychiatry in Canada.

    Penfold, P S

    1987-11-01

    A comparison of numbers of women psychiatrists with faculty appointments and women residents in Departments of Psychiatry in Canada in 1975 and 1985 showed that the average percentage of women faculty has increased from 11.4% to 14.3% and of women residents from 23.5% to 43.4%. Some departments appeared to be oblivious to the special educational role of women faculty and had not discussed the discrepancy between the numbers of faculty and residents. Only two departments were actively recruiting women faculty. The study also demonstrated a continued concentration of women in the lower ranks. Barriers to recruiting women faculty include lack of academic role models, job advertising not specifically designed to attract women candidates, rigid requirements for appointments, women's lack of access to male corridors of power, pervasive underlying doubts about women's abilities and competence based on cultural stereotypes, female socialization which does not lend itself readily to roles of authority, assertiveness and leadership, and the role strain that ensues when women psychiatrists try to combine career, marriage and motherhood. If women psychiatrists are to fill some of the positions in Departments of Psychiatry, which will fall vacant over the next decade, much more attention must be paid to eliminating or diminishing the multiple obstacles for women who chose a career in academic psychiatry.

    2012-12-01

    Climate variability and change can have profound impacts on the hydrologic regime of a watershed. These effects are likely to be especially severe in regions particularly sensitive to changes in climate, such as the Canadian north, or when there are other stresses on the hydrologic regime, such as may occur when there are large withdrawals from, or land-use changes within, a watershed. A recent report of the Intergovernmental Panel on Climate Change (IPCC) stressed that future climate is likely to accelerate the hydrologic cycle and hence may affect water security in certain locations. For some regions, this will mean enhanced access to water resources, but because the effects will not be spatially uniform, other regions will experience reduced access. Understanding these patterns is critical for water managers and government agencies in western Canada - an area of highly contrasting hydroclimatic regimes and overlapping water-use and jurisdictional borders - as adapting to climate change may require reconsideration of inter-regional transfers and revised allocation of water resources to competing industrial sectors, including agriculture, hydroelectric production, and oil and gas. This research involves the detection and examination of spatial and temporal streamflow trends in western Canadian rivers as a response to changing climatic factors, including temperature, precipitation, snowmelt, and the synoptic patterns controlling these drivers. The study area, known as the CROCWR region, extends from the Pacific coast of British Columbia as far east as the Saskatchewan-Manitoba border and from the Canada-United States international border through a large portion of the Northwest Territories. This analysis examines hydrologic trends in monthly and annual streamflow for a collection of 34 hydrometric gauging stations believed to adequately represent the overall effects of climate variability and change on flows in western Canada by means of the Mann-Kendall non

  7. From sea to sea: Canada's three oceans of biodiversity.

    Directory of Open Access Journals (Sweden)

    Philippe Archambault

    Full Text Available Evaluating and understanding biodiversity in marine ecosystems are both necessary and challenging for conservation. This paper compiles and summarizes current knowledge of the diversity of marine taxa in Canada's three oceans while recognizing that this compilation is incomplete and will change in the future. That Canada has the longest coastline in the world and incorporates distinctly different biogeographic provinces and ecoregions (e.g., temperate through ice-covered areas constrains this analysis. The taxonomic groups presented here include microbes, phytoplankton, macroalgae, zooplankton, benthic infauna, fishes, and marine mammals. The minimum number of species or taxa compiled here is 15,988 for the three Canadian oceans. However, this number clearly underestimates in several ways the total number of taxa present. First, there are significant gaps in the published literature. Second, the diversity of many habitats has not been compiled for all taxonomic groups (e.g., intertidal rocky shores, deep sea, and data compilations are based on short-term, directed research programs or longer-term monitoring activities with limited spatial resolution. Third, the biodiversity of large organisms is well known, but this is not true of smaller organisms. Finally, the greatest constraint on this summary is the willingness and capacity of those who collected the data to make it available to those interested in biodiversity meta-analyses. Confirmation of identities and intercomparison of studies are also constrained by the disturbing rate of decline in the number of taxonomists and systematists specializing on marine taxa in Canada. This decline is mostly the result of retirements of current specialists and to a lack of training and employment opportunities for new ones. Considering the difficulties encountered in compiling an overview of biogeographic data and the diversity of species or taxa in Canada's three oceans, this synthesis is intended to

    Incidence and prevalence estimates in myasthenia gravis have varied widely. Recent studies based on administrative health data have large sample sizes but lack rigorous validation of MG cases, and have not examined the North American population. Our aim was to explore trends in MG incidence and prevalence for the years 1996-2013 in the province of Ontario, Canada (population 13.5 million). We employed a previously validated algorithm to identify MG cases. Linking with census data allowed for the calculation of crude- and age/sex-standardized incidence and prevalence rates for the years 1996-2013. The regional distribution of MG cases throughout the province was examined. Mean age at the first myasthenia gravis encounter was 60.2 ± 17.1 years. In 2013, there were 3611 prevalent cases in Ontario, and the crude prevalence rate was 32.0/100,000 population. Age- and sex-standardized prevalence rates rose consistently over time from 16.3/100,000 (15.4-17.1) in 1996 to 26.3/100,000 (25.4-27.3) in 2013. Standardized incidence rates remained stable between 1996 (2.7/100,000; 95% CL 2.3-3.0) and 2013 (2.3/100,000; 2.1-2.6). Incidence was highest in younger women and older men, and geographic variation was evident throughout the province. In conclusion, this large epidemiological study shows rising myasthenia gravis prevalence with stable incidence over time, which is likely reflective of patients living longer, possibly due to improved disease treatment. Our findings provide accurate information on the Canadian epidemiology of myasthenia gravis and burden for health care resources planning for the province, respectively.

    2012-01-01

    With cases now documented in every province, Lyme borreliosis (LB) is emerging as a serious public health risk in Canada. Controversy over the contribution of LB to the burden of chronic disease is maintained by difficulty in capturing accurate Canadian statistics, especially early clinical cases of LB. The use of dogs as sentinel species demon-strates that potential contact with Borrelia burgdorferi spirochetes, as detected by C6 peptide, extends across the country. Dissemination of infected ticks by migratory birds and rapid establishment of significant levels of infection have been well described. Canadian public health response has focused on identification of established populations of the tick vectors, Ixodes scapularis and I. pacificus, on the assumption that these are the only important vectors of the disease across Canada. Strains of B. burgdorferi circulating in Canada and the full range of their reservoir species and coinfections remain to be explored. Ongoing surveys and historical records demonstrate that Borrelia-positive Ixodes species are regu-larly present in regions of Canada that have previously been considered to be outside of the ranges of these species in re-cent modeling efforts. We present data demonstrating that human cases of LB are found across the nation. Consequently, physician education and better early diagnoses are needed to prevent long term sequelae. An international perspective will be paramount for developing improved Canadian guidelines that recognize the complexity and diversity of Lyme borreliosis.

  15. Workplace health and safety: report from Canada.

    Science.gov (United States)

    Sass, R

    1986-01-01

    This article represents a critical analysis of the major policy responses to workplace health and safety in Canada. It examines the deficiencies inherent in the legislative development of Joint Health and Safety Committees in most Canadian jurisdictions, the limitations regarding standard-setting of worker exposure to contaminants, and disincentive for employers to positively improve the workplace because of Workers Compensation legislation. Collective bargaining agreements in Canada have had only limited positive effects, while the ultimate legal sanction of criminal prosecution by the regulatory agencies has weakened enforcement and compliance of existing regulations. There has never been a successful criminal prosecution of an employer in Canada, even for multiple deaths. The article suggests the following four reasons for this "underdevelopment" of occupational health and safety in Canada: the concealment of the dimension of the incidence of industrial disease based on Workers Compensation Board statistics; the application of an incorrect theory of causation of both industrial disease and injury by both managers and government administrators of occupational health and safety programs; the resistance of both senior and middle managers against increased worker participation in both work organization and job design questions; and the general "moral underdevelopment," rather than ignorance, of managers in favoring economic considerations or values at the expense of worker health and safety. In light of the magnitude of the problem and the deficiencies of existing policy approaches, the author proposes the need for greater workplace democratization of production and industry as a necessary and sufficient reform of workplace health and safety.

    2000-01-01

    Full Text Available To assess the risk of hepatitis C in Canada and to predict the burden that this disease may pose to the Canadian society in the near future, expected numbers of persons at different stages of the disease currently and in the next decade were estimated by simulation using a published hepatitis C natural history model with no treatment effect being applied. Based on the estimate of 240,000 persons who are currently infected with the hepatitis C virus in Canada, the simulation analysis demonstrated that the number of hepatitis C cirrhosis cases would likely increase by 92% from 1998 to the year 2008. It was also projected that the number of liver failures and hepatocellular carcinomas related to hepatitis C would increase by 126% and 102%, respectively, in the next decade. The number of liver-related deaths associated with hepatitis C is expected to increase by 126% in 10 years. The medical and social care systems in Canada may not be ready to support these large increases. These results highlight the importance of both the control of disease progression of hepatitis C virus-infected persons and the primary prevention of hepatitis C infections in Canada.

A sample survey carried out in 1962-63 distinguishes three types of returning migrant: (a) quasi-migrants who originally planned to return to Britain; (b) permanent repatriates who originally intended to settle in Canada but now expect to remain in Britain; (c) transilient migrants who exhibit a high propensity to move backwards and forwards between two or more countries without becoming permanently rooted in anyone. The demographic, economic and social characteristics of the three types are described. A further comparison is made between migrants who plan to settle in Britain, those who intend to come back again to Canada, and those who are uncertain of their future plans or who intend to move on to a third country.

    Canada is home to a growing immigrant population. However, immigrant mental health declines over time following arrival in Canada. Canada's Mental Health Strategy emphasizes the importance of research that gathers information from multiple sources of knowledge to identify the mental health challenges faced by diverse immigrant populations. Mixed methods research (MMR) is well suited for this task. However, a dearth of research exists on the application of MMR to the study of immigrant mental health. A systematic review of the published MMR literature in Canadian immigrant mental health was carried out. Overall, existing MMR studies failed to incorporate correct mixed methods terminology and fully integrate the quantitative and qualitative components of the research. A checklist of important elements to include in MMR studies is offered.

The data for this study are taken from the Canadian Fertility Survey of 1984. The results indicate that there is no immediate crisis for the family in Canada, but that many are choosing cohabitation as a preferred mode of first union formation at early stages. Young women (below 25 years of age), residents of large metropolitan areas, those with a university education and those with low religious commitment are more likely than others to be delayers of marriage."

    Characterization of the various microbial populations present in exoelectrogenic biofilms provides insight into the processes required to convert complex organic matter in wastewater streams into electrical current in bioelectrochemical systems (BESs). Analysis of the community profiles of exoelectrogenic microbial consortia in BESs fed different substrates gives a clearer picture of the different microbial populations present in these exoelectrogenic biofilms. Rapid utilization of fermentation end products by exoelectrogens (typically Geobacter species) relieves feedback inhibition for the fermentative consortia, allowing for rapid metabolism of organics. Identification of specific syntrophic processes and the communities characteristic of these anodic biofilms will be a valuable aid in improving the performance of BESs. © 2011 Elsevier Ltd.

    Full Text Available Since 2005, we have conducted three Atlantic Canada-wide surveys of SME businesses benchmarking levels of ICT adoption, change in adoption, as well as the role of marketing and export on ICT usage in helping to create growing and sustainable business opportunities. Despite Atlantic Canada’s low population base and distance to major population centres, SMEs in the region show strong levels of adoption of various ICT products and services. Broadband access, website adoption and online purchasing is now over 90%. Even newer socialnetworking services, such as web analytics, search engine optimization, and the use of Twitter are being adopted by as many of 44% of the SMEs. These adoption rates will be compared with our previous studies to document the historical growth within Atlantic Canada, as well as compare these baseline measures to other regions within Canada, as well as studies of comparable regions worldwide.

    As a conservative tracer, oxygen isotopes in seawater are widely used for water mass analysis, along with temperature and salinity. In this study, seawater oxygen-18 datasets in the Canada Basin during 1967-2010 were obtained from the four cruises of the Chinese National Arctic Research Expedition (1999, 2003, 2008, and 2010) and the NASA database. Fractions of sea ice meltwater and river runoff were determined from the salinity-δ18O system. Our results showed that the river runoff decreased from the south to the north in the Canada Basin. The enhanced amount of river runoff observed in the southern Canada Basin may originate from the Mackenzie River, transported by the Beaufort Gyre. The river runoff component showed maximum fractions during 1967-1969, 1978-1979, 1984-1985, 1993-1994, and 2008-2010, indicating the refresh time of the river runoff was 5.0-16.0 a in the Canada Basin. The temporal variation of the river runoff was related to the change of the Arctic Oscillation (AO) index, suggesting the freshwater stored in the Canada Basin was affected by surface sea ice drift and water mass movement driven by atmospheric circulation.

    Many scholars assert that Indigenous peoples across the globe suffer a disproportionate burden of mental illness. Research indicates that colonialism and its associated processes are important determinants of Indigenous peoples' health internationally. In Canada, despite an abundance of health research documenting inequalities in morbidity and mortality rates for Indigenous peoples, relatively little research has focused on mental health. This paper provides a critical scoping review of the literature related to Indigenous mental health in Canada. We searched eleven databases and two Indigenous health-focused journals for research related to mental health, Indigenous peoples, and Canada, for the years 2006-2016. Over two hundred papers are included in the review and coded according to research theme, population group, and geography. Results demonstrate that the literature is overwhelmingly concerned with issues related to colonialism in mental health services and the prevalence and causes of mental illness among Indigenous peoples in Canada, but with several significant gaps. Mental health research related to Indigenous peoples in Canada overemphasizes suicide and problematic substance use; a more critical use of the concepts of colonialism and historical trauma is advised; and several population groups are underrepresented in research, including Métis peoples and urban or off-reserve Indigenous peoples. The findings are useful in an international context by providing a starting point for discussions, dialogue, and further study regarding mental health research for Indigenous peoples around the world.

  18. Reforming health care in Canada: current issues

    Directory of Open Access Journals (Sweden)

    Baris Enis

    1998-01-01

    Full Text Available This paper examines the current health care reform issues in Canada. The provincial health insurance plans of the 1960s and 1970s had the untoward effects of limiting the federal government's clout for cost control and of promoting a system centered on inpatient and medical care. Recently, several provincial commissions reported that the current governance structures and management processes are outmoded in light of new knowledge, new fiscal realities and the evolution of power among stake-holders. They recommend decentralized governance and restructuring for better management and more citizen participation. Although Canada's health care system remains committed to safeguarding its guiding principles, the balance of power may be shifting from providers to citizens and "technocrats". Also, all provinces are likely to increase their pressure on physicians by means of salary caps, by exploring payment methods such as capitation, limiting access to costly technology, and by demanding practice changes based on evidence of cost-effectiveness.

    Cysts of Giardia sp. were detected in feces from the rectum of 20 of 74 pinnipeds examined from the eastern coast of Canada in 1997 and 1998 using a monoclonal antibody technique. Infected pinnipeds included 15 adult harp seals (Phoca groenlandica), four adult grey seals (Halichoerus grypus), and one juvenile harbor seal (Phoca vitulina). Cysts were not detected in 15 seal pups St. Lawrence. The overall prevalence of Giardia sp. in grey and harbor seals, excluding pups, from the Gulf and St. Lawrence estuary was 23%. Feces from 11 beluga (Delphinapterus leucas) and one northern bottle-nosed whale (Hyperoodon ampullatus) stranded in the St. Lawrence estuary were negative for Giardia sp. cysts. The significance of Giardia sp. in marine mammals, shown here for the first time in eastern coastal Canada, is unknown.

    Biomaterials research in Canada began in the 1960s. Over the past four decades significant contributions have been made across a broad spectrum covering dental, orthopaedic, cardiovascular, neuro, and ocular biomaterials. Canadians have also been active in the derivative area of tissue engineering. Biomaterials laboratories are now established in universities and research institutes from coast to coast, supported mainly by funding from the Federal and Provincial Governments. The Canadian Biomaterials Society was formed in 1971 and has played an important role in the development of the field. The Society played host to the 5th World Biomaterials Congress in Toronto in 1996. The work of Canadian researchers over the past four decades is summarized briefly. It is concluded that biomaterials and tissue engineering is a mature, strong area of research in Canada and appears set to continue as such into the future.

    Full Text Available Background . Canada's North is a diverse, sparsely populated land, where inequalities and public health issues are evident, particularly for Aboriginal people. The Northern public health workforce is a unique mix of professional and paraprofessional workers. Few have formal public health education. From 2009 to 2012, the Public Health Agency of Canada (PHAC collaborated with a Northern Advisory Group to develop and implement a strategy to strengthen public health capacity in Canada's 3 northern territories. Access to relevant, effective continuing education was identified as a key issue. Challenges include diverse educational and cultural backgrounds of public health workers, geographical isolation and variable technological infrastructure across the north. Methods . PHAC's Skills Online program offers Internet-based continuing education modules for public health professionals. In partnership with the Northern Advisory Group, PHAC conducted 3 pilots between 2008 and 2012 to assess the appropriateness of the Skills Online program for Northern/Aboriginal public health workers. Module content and delivery modalities were adapted for the pilots. Adaptations included adding Inuit and Northern public health examples and using video and teleconference discussions to augment the online self-study component. Results . Findings from the pilots were informative and similar to those from previous Skills Online pilots with learners in developing countries. Online learning is effective in bridging the geographical barriers in remote locations. Incorporating content on Northern and Aboriginal health issues facilitates engagement in learning. Employer support facilitates the recruitment and retention of learners in an online program. Facilitator assets included experience as a public health professional from the north, and flexibility to use modified approaches to support and measure knowledge acquisition and application, especially for First Nations, Inuit and

  3. Power Imbalances, Food Insecurity, and Children's Rights in Canada.

    Blay-Palmer, Alison

    2016-01-01

    Increasingly, food is provided through an industrial food system that separates people from the source of their food and results in high rates of food insecurity, particularly for the most vulnerable in society. A lack of food is a symptom of a lack of power in a system that privileges free market principles over social justice and the protection of human rights. In Canada, the high rates of food insecurity among Canadian children is a reflection of their lack of power and the disregard of their human rights, despite the adoption of the United Nations (UN) Convention on the Rights of the Child in 1991 and ratification of the International Covenant on Social, Economic and Cultural Rights in 1976, which established the right to food for all Canadians. Dueling tensions between human rights and market forces underpin this unacceptable state of affairs in Canada. Gaventa's "power cube" that describes different facets of power - including spaces, levels, and forms - is used to help understand the power imbalances that underlie this injustice. The analysis considers the impact of neoliberal free market principles on the realization of human rights, and the negative impacts this can have on health and well-being for the most vulnerable in society. Canadian case studies from both community organizations provide examples of how power can be shifted to achieve more inclusive, rights-based policy and action. Given increased global pressures toward more open trade markets and national austerity measures that hollow out social supports, Canada provides a cautionary tale for countries in the EU and the US, and for overall approaches to protect the most vulnerable in society.

    Canada's latest wind farm, the 20-turbine Magrath Wind Power project, a $48 million joint venture between Suncor, EHN Wind Power Canada Inc., and Enbridge Inc. is described. This latest addition to Canada's growing renewable energy generation capacity is situated near the town of Magrath in Alberta, 40 km south of Lethbridge. The 20 turbines are erected along a distance of eight kilometres; they are capable of generating enough electricity to light approximately 13,000 homes. Each hub stands 65 metres above the ground, equivalent in height to a 23-story building; the turbine's bladespan is 34 metres, which is close to the wingspan of a Boeing 737-900 airliner. The Magrath is Suncor's second wind power project, and is part of the oil giant's continuing commitment to the development of renewable energy sources as a means of providing a reliable source of electricity and protect the environment at the same time. The construction activity took three months over a 12-month period and provided employment for 70 people at the peak construction period. Each turbine generates 1.5 megawatts of energy, and will offset 82,000 tons of carbon dioxide emissions annually (equivalent to the removal of 12,000 cars from Canadian roads). At present, the cost of generating wind energy ranges between 6 cents and 12 cents per kilowatt-hour, depending on location, compared to about 5 cents for electricity generated by hydro power. The Magrath Wind Power project joins 30 other wind farms currently in operation in Canada.

    POSITION STATEMENT It is the position of Dietitians of Canada that household food insecurity is a serious public health issue with profound effects on physical and mental health and social well-being. All households in Canada must have sufficient income for secure access to nutritious food after paying for other basic necessities. Given the alarming prevalence, severity and impact of household food insecurity in Canada, Dietitians of Canada calls for a pan-Canadian, government-led strategy to specifically reduce food insecurity at the household level, including policies that address the unique challenges of household food insecurity among Indigenous Peoples. Regular monitoring of the prevalence and severity of household food insecurity across all of Canada is required. Research must continue to address gaps in knowledge about household vulnerability to food insecurity and to evaluate the impact of policies developed to eliminate household food insecurity in Canada. Dietitians of Canada recommends: Development and implementation of a pan-Canadian government-led strategy that includes coordinated policies and programs, to ensure all households have consistent and sufficient income to be able to pay for basic needs, including food. Implementation of a federally-supported strategy to comprehensively address the additional and unique challenges related to household food insecurity among Indigenous Peoples, including assurance of food sovereignty, with access to lands and resources, for acquiring traditional/country foods, as well as improved access to more affordable and healthy store-bought/market foods in First Nation reserves and northern and remote communities. Commitment to mandatory, annual monitoring and reporting of the prevalence of marginal, moderate and severe household food insecurity in each province and territory across Canada, including among vulnerable populations, as well as regular evaluation of the impact of poverty reduction and protocols for

    Objective : Orofacial clefts such as cleft lip, cleft palate, and cleft lip and palate are the most frequent congenital anomalies of the head and neck. The purpose of this study was to determine the current demographics for orofacial clefts in Canada. Methods : A request for data from all Canadian provinces (excluding Quebec due to incompatibilities with provincial coding systems) for the fiscal years 2002-2003 to 2007-2008 was submitted to the Canadian Institute for Health Information. Variables evaluated included gender, cleft type, gestational age, birth weight, income quintile, and institution health region. Results : Over the period studied, the prevalence of orofacial clefts ranged from 11.0 to 15.3 per 10,000 live births (1 in 654 to 1 in 909 live births). The distribution of cleft types for live births with orofacial clefts was 17% for cleft lip, 41% for cleft palate, and 42% for cleft lip and palate, of which cleft lip and cleft lip and palate were male dominant (62% and 66% male, respectively) and cleft palate was female dominant (56% female). Saskatchewan and Manitoba had significantly higher cleft birthrates (P orofacial clefting compared with those with no cleft. Conclusions : Canada has one of the highest orofacial cleft birthrates in the world (prevalence of 12.7 per 10,000 live births, approximately 1 in 790 live births). This study presents an updated demographic of orofacial clefts in Canadian newborns and may be useful in predicting the burden of anticipated health care.

    Full Text Available This two-phase study deals with the phenomenon of “stealth advertising” in Canada. This concept refers to the encroachment of commercially tinted messages into broadcast news segments. Different theories of commercial speech were used as a theoretical framework. The study combined mixed methods, content analysis and in-depth interviews. The first phase concentrated on the frequency and actual time spent airing commercially influenced messages in television newscast segments. The sample consisted of eight randomly selected English-language markets across Canada including news stations affiliated with CBC, CTV and Global. Seventy-five newscasts were recorded and content-analyzed. The analysis demonstrated that private television stations used more explicit and aggressive stealth advertising than publicly owned ones. In subsequent interviews, the news directors and sales managers of some of these stations denied that they yield to outside commercial pressures but admitted they may include messages with commercial content if these have public interest value. In the second phase thirty-nine newscasts of a news station affiliated with Global were recorded and content-analyzed, showing high numbers of commercially influenced messages and corroborating previous research findings. Subsequent interviews showed some news decision-makers accept the inclusion of commercially tinted news segments, thus eroding the divide between editorial and commercial contents. This study is intended to contribute to the empirical basis for pursuing the question of corruption of news by surreptitious commercial content.

    Full Text Available Post-secondary distance education gives students and their families living in remote and rural regions the option to stay in their communities while they study instead of moving closer to the universities in cities. Post-secondary distance education is an option in many rural and remote First Nation (Indigenous communities in Canada; however there are many challenges to successful adoption in these communities. There are also many opportunities for post-secondary institutions to expand their abilities and capacity in developing and delivering appropriate content supporting these unique, self-governing environments in Canada. We explore the experiences of students from a rural First Nation in Canada with post-secondary distance education, focusing on how different delivery methods offer both opportunities and challenges for community-based students. The study is situated in the context of contemporary colonialism in Canada.

    2016-04-01

    Environment and Climate Change Canada has been providing air quality (AQ) forecasts for major Canadian urban centers since 2001. Over this period, the Canadian AQ Forecast Program has expanded and evolved. It currently uses the Regional Air Quality Deterministic Prediction System (RAQDPS) modelling framework. At the heart of the RAQDPS is the GEM-MACH model, an on-line coupled meteorology‒chemistry model configured for a North American domain with 10 km horizontal grid spacing and 80 vertical levels. A statistical post-processing model (UMOS-AQ) is then applied to the RAQDPS hourly forecasts for locations with AQ monitors to reduce point forecast bias and error. These outputs provide the primary guidance from which operational meteorologists disseminate Air Quality Health Index (AQHI) forecasts to the public for major urban centres across Canada. During the 2015 summer Pan Am and Parapan Am Games, which were held in Ontario, Canada, an experimental version of the RAQDPS at 2.5 km horizontal grid spacing was run for a domain over the greater Toronto area. Currently, there is ongoing research to develop and assess AQ systems run at 1 km resolution. This presentation will show analyses of operational AQ forecast performance for several pollutants over the last few years in major Canadian urban centres such as Toronto, Montreal, Vancouver, Ottawa, and Calgary. Trends in observed pollution along with short- and long-term development plans for urban AQ forecasting will also be presented.

  13. An emissions trading regime for Canada

    Smith, S.L. [National Round Table on the Environment and the Economy, Ottawa, ON (Canada)

    2001-07-01

    In 1998, over twelve papers were published on emissions trading regimes in Canada by the National Round Table on the Environment and the Economy (NRTEE), a federal government agency whose members represent stakeholders as varied as business, environmental groups, academics, aboriginal groups and others. One of the recommendations that emerged was for the computer modelling of the possibilities that had been identified for a domestic trading regime in Canada for greenhouse gases. It is unclear whether the modelling was ever performed as the file was taken over by the Finance Department under the umbrella of a special emission trading table that examined Canada's commitment under the Kyoto Protocol. The author examined questions pertaining to whether a domestic trading regime is essential, and what its characteristics should be in case it was deemed essential or advisable to have one. The upstream versus downstream application was looked at, as well as grand-fathering versus auction. Provincial issues were then addressed, followed by meshing with a credit system. International systems were reviewed. Early action was discussed, whereby an emitter seeks credit for action taken toward reductions since the original reference year of 1990. The case of emitters having bought or sold permits since the original reference years will also want those trades recognized under a trading regime. The author indicated that it seems probable that an emission trading system will eventually be implemented and that a debate on the issue should be initiated early.

    Full Text Available Canada faces health care challenges common to all industrialized countries – how to ensure timely access to high quality care, close to home, at an affordable cost. Addressing these challenges is complicated by interjurisdictional variation in both how health care is managed and delivered, and in health outcomes. Canada can be described as a non-system of 10 provincial and three territorial health insurance plans which mandate publicly-funded coverage for medically necessary hospital and physician services, based upon common principles and shaped by a federal governance structure that affords substantial power and autonomy to the provinces/territories over matters of health and health care. This article first examines the structural context of the health care system in Canada, including the range of services publicly funded, the public-private mix, and the complexities of current governance arrangements. It then discusses several issues affecting health policy reform: costs versus access; questions of sustainability, quality, and performance; human resources capacity; and the provision of public and population health services.

    Superovulation of dairy cattle is frequently used in Canada. The cost of this protocol is high, and so is the variability of the outcome. Knowing the superovulatory potential of a donor cow could influence the breeder's decision to superovulate it or not. The main objective of this study was to perform a genetic analysis for superovulatory response of Holstein cows in Canada using data recorded by Holstein Canada, and to investigate if these data could be used for genetic evaluation. Data contained the total number of embryos and the number of viable embryos from every successful flushing performed across Canada. After editing, 137,446 records of superovulation performed between 1992 and 2014 were analyzed. A univariate repeatability animal model analysis was performed for both total number of embryos and number of viable embryos. Because both data and residuals did not follow a normal distribution, records were subject to either logarithmic or Anscombe transformation. Using logarithmic transformation, heritability estimates (SE) of 0.15 (0.01) and 0.14 (0.01) were found for total number of embryos and number of viable embryos, respectively. Using Anscombe transformation, heritability estimates (SE) of 0.17 (0.01) and 0.14 (0.01) were found for total number of embryos and number of viable embryos, respectively. The genetic correlation between the 2 traits was estimated at 0.97 using logarithmic transformation and 0.95 using Anscombe transformation. Breeding values were estimated for 54,463 cows, and 3,513 sires. Only estimated breeding values of sires having a reliability higher than 40% were considered for estimated breeding values correlations with other routinely evaluated traits. The results showed that selection for a higher response to superovulation would lead to a slight decrease in milk production, but an improvement for functional traits, including all reproduction traits. In all cases, the estimated correlations are either low or modest. We conclude that

    Full Text Available This paper is the first to consider braconid parasitoid wasps in conservation efforts in Canada. Out of the 28 genera of the subfamily Microgastrinae (Hymenoptera: Braconidae present in the country, 13 genera were studied and 16 species were identified as potential candidates to be included in the Species Candidate Lists of COSEWIC (The Committee on the Status of Endangered Wildlife in Canada. For every selected species a brief summary of its broad geographical distribution is provided, with detailed and in many cases new information of its distribution and collecting dates in Canada, hosts (Lepidoptera if known, and color pictures of all wasp species. A preliminary assessment is made using Prioritization Criteria developed by COSEWIC, and some general recommendations are made based in those analyses.

  20. Public Education and Multicultural Policy in Canada: The Special Case of Quebec

    Science.gov (United States)

    Ghosh, Ratna

    2004-11-01

    Education is a provincial responsibility in Canada, but there is a sharing of expenditure and strong support of public education, health and other welfare programs between the provinces and the federal government. Although the federal policy of multiculturalism has been aimed at making Canada a `just' society, the implementation of this policy in education in English-speaking Canada has been far from satisfactory, and there is great variation among the provinces in educational programs. In Quebec, the federal policy of multiculturalism is ideologically opposed to the vision of French-Québécois nationalism. While the federal policy of intercultural education has made some attempts to integrate immigrant populations, the focus remains on linguistic programs. In facing the dramatic changes driven by internationalization and a globalized economy, Canadians must respond - so the conclusion of the present study - to the urgent need to redefine the meaning of multiculturalism with radical educational programs.

    Background Although death rates are often used to monitor the quality of health care, in industrialized countries maternal deaths have become rare. Severe maternal morbidity has therefore been proposed as a supplementary indicator for surveillance of the quality of maternity care. Our purpose in this study was to describe severe maternal morbidity in Canada over a 10-year period, among women with or without major pre-existing conditions. Methods We carried out a retrospective cohort study of severe maternal morbidity involving 2 548 824 women who gave birth in Canadian hospitals between 1991 and 2000. Thirteen conditions that may threaten the life of the mother (e.g., eclampsia) and 11 major pre-existing chronic conditions (e.g., diabetes) that could be identified from diagnostic codes were noted. Results The overall rate of severe maternal morbidity was 4.38 per 1000 deliveries. The fatality rate among these women was 158 times that of the entire sample. Rates of venous thromboembolism, uterine rupture, adult respiratory distress syndrome, pulmonary edema, myocardial infarction, severe postpartum hemorrhage requiring hysterectomy, and assisted ventilation increased substantially from 1991 to 2000. The presence of major pre-existing conditions increased the risk of severe maternal morbidity to 6-fold. Interpretation Severe maternal morbidity occurs in about 1 of 250 deliveries in Canada, with marked recent increases in certain morbid conditions such as pulmonary edema, myocardial infarction, hemorrhage requiring hysterectomy, and the use of assisted ventilation.

  2. From Early Exploration to Space Weather Forecasts: Canada's Geomagnetic Odyssey

    2011-05-01

    Canada is a region ideally suited for the study of space weather: The north magnetic pole is encompassed within its territory, and the auroral oval traverses its vast landmass from east to west. Magnetic field lines link the country directly to the outer magnetosphere. In light of this geographic suitability, it has been a Canadian tradition to install ground monitors to remotely sense the space above Canadian territory. The beginning of this tradition dates back to 1840, when Edward Sabine, a key figure in the “magnetic crusade” to establish magnetic observatories throughout the British Empire in the nineteenth century, founded the first Canadian magnetic observatory on what is now the campus of the University of Toronto, 27 years before the birth of Canada. This observatory, which later became the Toronto Magnetic and Meteorological Observatory, marked the beginning of the Canadian heritage of installing magnetic stations and other ground instruments in the years to come. This extensive network of ground-based measurement devices, coupled with space-based measurements in more modern times, has enabled Canadian researchers to contribute significantly to studies related to space weather.

  3. Report summary Prevalence and monetary costs of dementia in Canada (2016): a report by the Alzheimer Society of Canada.

    2016-10-01

    Dementia prevalence estimates vary among population-based studies, depending on the definitions of dementia, methodologies and data sources and types of costs they use. A common approach is needed to avoid confusion and increase public and stakeholder confidence in the estimates. Since 1994, five major studies have yielded widely differing estimates of dementia prevalence and monetary costs of dementia in Canada. These studies variously estimated the prevalence of dementia for the year 2011 as low as 340 170 and as high as 747 000. The main reason for this difference was that mild cognitive impairment (MCI) was not consistently included in the projections. The estimated monetary costs of dementia for the same year also varied, from $910 million to $33 billion. This discrepancy is largely due to three factors: (1) the lack of agreed-upon methods for estimating financial costs; (2) the unavailability of prevalence estimates for the various stages of dementia (mild, moderate and severe), which directly affect the amount of money spent; and (3) the absence of tools to measure direct, indirect and intangible costs more accurately. Given the increasing challenges of dementia in Canada and around the globe, reconciling these differences is critical for developing standards to generate reliable information for public consumption and to shape public policy and service development.

    Full Text Available The objective of this study is to identify strengths and weaknesses of Brazil and Canada regarding the production of coniferous sawn timber, based on an opinion survey with entrepreneurs operating in that business segment. The method selected for use was cluster analysis and results led to the conclusion that Brazil's main strengths relate to the expansion potential of its domestic and export markets and also to the high productivity and profitability of its forests, while, as for Canada, in addition to having an extensive area with commercial forests, a major strength is the commitment of the Canadian government to provide adequate infrastructure for the sawn timber industry to operate effectively.

  5. Exploring an Olympic "Legacy": Sport Participation in Canada before and after the 2010 Vancouver Winter Olympics.

    Science.gov (United States)

    Perks, Thomas

    2015-11-01

    Guided by the notion of a trickle-down effect, the present study examines whether sport participation in Canada increased following the 2010 Winter Olympics in Vancouver. Comparing rates of sport participation prior to and following the Games using nationally representative data, the results suggest that the Olympics had almost no impact on sport participation in Canada, although there does appear to be a modest "bounce" in sport participation in the Vancouver area immediately following the Vancouver Games. As such, if the trickle-down effect did occur, the analysis suggests that the effect was locally situated, short-lived, and small.

    2009-03-01

    South Asians in Canada often apply the traditional custom of arranged marriage across international borders, leading to male sponsorship of family-chosen brides from their home countries. This qualitative study examined understandings of sponsorship and marital/resettlement experiences among English-proficient and non-English-proficient South Asian brides who entered Canada after recent immigration policy changes to reduce sponsored women's vulnerability to maltreatment. English-proficient women were aware of their rights and permanent resident status, and reported significant integration support. In contrast, non-English-proficient women misunderstood sponsorship and faced multiple barriers to participation in Canadian life, along with severe abuse and neglect.

  8. Making Canada a destination for medical tourists: why Canadian provinces should not try to become "Mayo Clinics of the North".

    Science.gov (United States)

    Turner, Leigh

    2012-05-01

    When Canadian researchers examine the subject of medical tourism, they typically focus on ethical, social, public health and health policy issues related to Canadians seeking health services in other countries. They emphasize study of Canada as a departure point for medical tourists rather than as a potential destination for international patients. Several influential voices have recently argued that provincial healthcare systems in Canada should market health services to international patients. Proponents of marketing Canada as a destination for medical tourists argue that attracting international patients will generate revenue for provincial healthcare systems. Responding to such proposals, I argue that there are at least seven reasons why provincial health systems in Canada should not dedicate institutional, financial and health human resources to promoting themselves as destinations for medical tourists.

  9. Real wages in Australia and Canada, 1870-1913

    2000-01-01

    Australia's and Canada's real wage experiences between 1870 and 1913 were distinctive. Faster productivity growth underpinned Canada's overtaking of Australia's wage levels. The globalization forces of migration and trade also shaped their comparative wages, principally by reducing wage growth...... in Canada. Immigration increased slightly Australia's real wages, but reduced wage levels in Canada, and tempered there the beneficial effects of rising productivity and improving terms of trade. In contrast, wage earners' share of national income rose after 1890 in Australia, with the productivity slowdown...... hitting chiefly rents and profits. Distributional shifts favouring wage earners in Australia, and the depressing effects of mass immigration on wages in Canada, limited Canada's wage lead before 1914, despite her faster productivity growth...

    2016-12-01

    Unlike probabilistic seismic hazard analysis (PSHA), there is not a well-established methodology for probabilistic tsunami hazard analysis (PTHA). The PTHA methodology presented is similar to the widely used PSHA methodology for ground motion, and incorporates both aleatory and epistemic uncertainty in calculating the probability of exceeding runup and drawdown values produced by tsunamigenic sources. Evaluating tsunami hazard is more difficult in locations such as the eastern coastline of Canada because of low tsunami recurrence rates and few historical examples. In this study, we evaluated the hazard from local and far-field earthquake and landslide tsunamigenic sources at a site on the Bay of Fundy in New Brunswick, Canada. These sources included local faults, the Puerto Rico subduction zone, fault sources in the Azores-Gibraltar plate boundary region, and landslides on the Canadian continental slope and in the Canary Islands. Using a new PTHA methodology that is closely linked to well-established PSHA methodology combined with tide stage probability, we calculated that the return period for a wave runup exceeding the tidal range of +4 m level above mean sea level (highest astronomical tide) is approximately 14,500 years.

  11. Nuclear waste management in Canada : critical issues, critical perspectives

    Energy Technology Data Exchange (ETDEWEB)

    Durant, D.; Fuji Johnson, G. (eds.)

    2009-07-01

    As oil reserves decline and the environment takes centre stage in public policy discussions, the merits and dangers of nuclear power and nuclear waste management continue to be debated. Canada is intent on building more reactors to increase energy production without destroying the planet, but it and other nuclear energy-producing countries face not only technical problems but also social and ethical issues. This book provides a critical antidote to the favourable position of government and industry. The contributors build their case by exploring key issues and developments. What do frequently used terms such as safety, risk, and acceptability really mean? How and why did the public consultation process in Canada fail to address ethical and social issues? What is the significance and potential of a public consultation process that involves diverse interests, epistemologies, and actors, including Aboriginal peoples? And how do we ensure that our frameworks for discussion are inclusive and ethical? This timely collection defuses the uncertainty, ambiguity, and ignorance that surrounds nuclear energy. It will appeal to academics, students, and stakeholders in public policy or environmental studies who want to think critically and more broadly about how we approach energy generation and waste management.

    Although occupational therapists have been practicing in forensic settings for many years, there is a paucity of literature regarding the nature of this practice in Canada. The purpose of this study was to describe the practices of Canadian occupational therapists in forensic mental health. An online survey was designed based on the Canadian Practice Process Framework. Following purposive and snowball sampling, responses were analysed with descriptive statistics and content analysis. Twenty-seven clinicians responded (56% response rate). Respondents indicated commonalities in workplaces, client caseloads and practice challenges. The outstanding need in Canada to demonstrate client outcomes through the use of evaluation instruments reflects those practice gaps identified internationally. Education, advocacy and research are critical areas for the development of Canadian forensic occupational therapy. Although findings heavily reflect one provincial context and may not be generalizable to nonhospital settings, a number of priority areas were identified. Future efforts should clarify the role of forensic occupational therapy to stakeholders, and validate their contributions through research that evaluates intervention efficacy and meaningful outcomes.

    Full Text Available Measurement of the impact and influence of medical/scientific journals, and of individual researchers has become more widely practiced in recent decades. This is driven, in part, by the increased availability of data regarding citations of research articles, and by increased competition for research funding. Digestive disease research has been identified as a particularly strong discipline in Canada. The authors collected quantitative data on the impact and influence of Canadian digestive health research. The present study involved an analysis of the research impact (Hirsch factor and research influence (Influence factor of 106 digestive health researchers in Canada. Rankings of the top 25 researchers on the basis of the two metrics were dominated by the larger research groups at the University of Toronto (Toronto, Ontario, McMaster University (Hamilton, Ontario, and the Universities of Calgary (Calgary, Alberta and Alberta (Edmonton, Alberta, but with representation by other research groups at the Universities of Manitoba (Winnipeg, Manitoba, Western Ontario (London, Ontario and McGill University (Montreal, Quebec. Female and male researchers had similar scores for the two metrics, as did basic scientists versus clinical investigators. Strategic recruitment, particularly of established investigators, can have a major impact on the ranking of research groups. Comparing these metrics over different time frames can provide insights into the vulnerabilities and strengths of research groups.

    Canada has been a leader in tritium handling technologies as a result of the successful CANDU reactor technology used for power production. Over the last 50 to 60 years, capabilities have been established in tritium handling and tritium management in CANDU stations, tritium removal processes for heavy and light water, tritium measurement and monitoring, and understanding the effects of tritium on the environment. This paper outlines details of tritium-related work currently being carried out at Atomic Energy of Canada Limited (AECL). It concerns the CECE (Combined Electrolysis and Catalytic Exchange) process for detritiation, tritium-compatible electrolysers, tritium permeation studies, and tritium powered batteries. It is worth noting that AECL offers a Tritium Safe-Handling Course to national and international participants, the course is a mixture of classroom sessions and hands-on practical exercises. The expertise and facilities available at AECL is ready to address technological needs of nuclear fusion and next-generation nuclear fission reactors related to tritium handling and related issues.

  11. Nuclear power in Canada : an examination of risks, impacts and sustainability

    Energy Technology Data Exchange (ETDEWEB)

    Winfield, M.; Jamison, A.; Wong, R.; Czajkowski, P.

    2006-12-15

    This study examines the environmental impacts of the use of nuclear energy for electricity generation in Canada through each of the four major stages of nuclear energy production: uranium mining and milling; uranium refining, conversion and fuel fabrication; nuclear power plant operation; and waste fuel management. It is intended to inform public debate over the future role of nuclear energy in Canada, and to facilitate comparisons of nuclear energy with other potential energy sources. The study examines waste generation, atmospheric releases, impacts on water quality and water use, and landscape and ecosystem impacts of nuclear energy production. It also examines the occupational and community health impacts of nuclear power and key long-term challenges to its sustainability, including security and weapons proliferation risks. Specific environmental impacts are examined in the context of CANDU nuclear technology, the only reactor type currently in use in Canada. The study findings likely underestimate the overall impacts of the use of nuclear energy for electricity production in Canada. This is a result of significant gaps in the publicly available information on releases of pollutants and contaminants, as well as on the fate of certain waste streams related to the nuclear industry. In addition, the study relies on what are likely conservative estimates in a number of key areas, particularly with respect to the generation of greenhouse gas (GHG) emissions.

    Full Text Available Background and objectives. Inuit populations may be at increased risk for experiencing poor nutrition or hunger due to limited access and availability to food. The prevalence and correlates of parental perceptions of hunger among a nationally representative sample of Inuit children in Canada have not yet been reported. Design. Data are from the 2006 Aboriginal Children's Survey (ACS. Sociodemographic information, dietary behaviours and hunger status were parent-reported via a household interview for Inuit children aged 2–5 years (n=1,234. Prevalence of hunger was calculated among Inuit children by sociodemographic factors and by dietary behaviours. In addition, a multivariate logistic regression model was conducted to determine factors associated with parental perception of ever experiencing hunger. Results. The prevalence of Inuit children in Canada aged 2–5 years ever experiencing hunger was 24.4%. Children who were reported to have experienced hunger consumed milk and milk products (p<0.001; fish, eggs and meat (p<0.05; fruits (p<0.001; and vegetables (p<0.001 significantly less often than never-hungry children. Fast food and processed foods, soft drinks and juice, and salty snacks, sweets and desserts were consumed as often as never-hungry children (all p>0.05. The majority (81% of Inuit parents/guardians of ever-hungry children sought help from family or friends. Factors associated with an increased likelihood of experiencing hunger include sociodemographic characteristics (such as income and household size, living in an Inuit region and living in a community with cultural activities. Conclusion. About 1 in 4 Inuit children were reported by their parents to have experienced hunger, and hunger was associated with region, sociodemographic and community factors. Future research could further examine the impact of ever experiencing hunger on the health status of Inuit children and their families in Canada.

    This presentation provided a broad overview of the geopolitical issues affecting the massive transformation of the Arctic resulting from resource development, globalization, and climate change. Two Arctics are emerging, notably one European and one North American. Oil and gas companies are investing heavily in the North, and there is continued debate over pipelines and projects, but the viability of projects can shift abruptly from technological and political change. Recent examples include the emergence of shale gas, the possibility of the United States becoming a gas exporter, and the Deepwater Horizon disaster. In terms of Maritime jurisdictions and boundaries, a comparison was presented regarding the Canadian and Russian claims to the continental shelf. International cooperation and a commitment to peaceful means can be seen in the Ilulissat Declaration, the acceptance of the United Nations Convention of the Law of the Sea as rules, the scientific cooperation of Canada, the United States, and Denmark, and the recent boundary agreement between Russia and Norway. The positions of the main players in the new geopolitics of the North were outlined, particularly with respect to Russia, the United States, Norway, Denmark, and Canada. Their recent policy statements and developing arctic force capabilities were summarized. Canada's more assertive Arctic policy was outlined in more detail along with the country's base locations and recent security actions in the North. The main issues facing nations with interests in the North will be maritime and aerospace; understanding the new players on the scene; and new technological developments. 10 figs., 5 refs.

    This expert panel report was commissioned by the Royal Society of Canada to provide a comprehensive evidence-based assessment of the environmental and health impacts of Canada's oil sands industry. The report evaluated the feasibility of land reclamation and the impacts of oil sands contaminants on downstream residents. Health impacts on residents living in the Regional Municipality of Wood Buffalo were assessed, and the impacts on regional water supplies were evaluated. Regional water and ground water quantities were examined, and issues related to tailing pond operations and reclamation were examined. Ambient air quality impacts were assessed, as well as potential impacts of the oil sands industry on greenhouse gas (GHG) emissions. The environmental regulatory performance of operators in the industry was also evaluated. A summary of economic and policy issues related to the industry was also provided. The study identified major gaps in the process of assessment, prevention, and mitigation of the health impacts of oil sands exploitation, as as major indirect health impacts linked to past exploitation activities. 672 refs., 11 tabs., 11 figs. 10 appendices.

    The drop in income poverty among the elderly in Canada over the last generation has been well-documented. In this paper, I extend the calculation of head-count measures of poverty to all currently available microdata, spanning the years 1973 to 2003. I then generate consumption poverty measures spanning 1969 to 2004 and compare to the income poverty results. For both income and consumption, I implement a relative poverty measure that uses the wellbeing of working age families as a benchmark f...

    Citizen engagement through deliberative dialogue is increasingly being used to address 'wicked problems' in policy-making, such as the development of national mental health policy. In 2012, the Mental Health Commission of Canada (MHCC), a national organization funded by and operating at arm's length from the federal government, released the first Mental Health Strategy for Canada: Changing Directions, Changing Lives (Mental Health Commission of Canada, 2012). Despite much-needed reform, Canada, unlike most other industrialized countries, had never previously developed a national Mental Health Strategy (the Strategy). This was due to a mix of policy factors, including a federalist system of government where primary responsibility for healthcare resides with provincial and territorial governments and a highly diverse set of stakeholder groups with diverging core ideas for mental health reform that were rooted in deeply held value differences. In this case study, we review the essential role that engagement of civil society played in the creation of the Strategy, beginning with the efforts to create a national body to shine the light on the need for mental health reform in Canada, followed by the development of a framework of specific goals based on core principles to guide the development of the Strategy, and ultimately, the creation of the Strategy itself. We discuss the various approaches to civil society engagement in each step of this process and focus in particular on how deliberative approaches helped build trust and common ground amongst stakeholders around complex, and often contentious, issues. The nature and outcomes of the deliberative processes including the key tensions between different stakeholder perspectives and values are described. We close by highlighting the lessons learned in a process that culminated with a Strategy that received strong endorsement from stakeholders across Canada. Mental Health Commission of Canada (2012).

    2002-12-01

    Full Text Available In this article the author attempts to describe the life of Croatian immigrants in Canada duringthe interwar period. She looks at how emigration to Canada effected family life, especially for men who went abroad in search of work and higher earnings. To begin the article, the author surveys the existing historiography, in particular the new trends in social history that examine the everyday life of “average” men and women which have opened new approaches in immigration history, paying less attention to the political and diplomatic events surrounding migration studies. Her methodological approach follows concepts developed by the “new” social history and is based on a theoretical concept of masculinity. The major primary source for her research is Canadian/Croatian Voice which was printed in Canada in Croatian, but she also leans heavily on important historiographical literature concerning Croatian immigrants in Canada. In her article the author provides a short survey of the emigration of Croatians to Canada which grows after an agreement was signed in 1925 between the Canadian government and the two large railway companies, Canadian Pacific Railway and Canadian National Railway. The major portion of the work examines the life of Croatian men in isolated labour camps, the hard working conditions, the constant search for work, and the psychological effects of long years of separation from family. Men leave for Canada with the intent of staying for only a certain period of time in order to bring money back home. But in the event of the economic crisis created by the Great Depression, low wages, and periods of unemployment, the length of the stay in Canada grows, creating frustration among the immigrant men as well as their families back home. In conclusion, the author shows how improving economic conditions in Canada in the mid 1930s coupled with worsening conditions in the Kingdom of Yugoslavia led most men to find steady employment in

    We examined whether access to US-approved orphan drugs in Canada has changed between 1997 (when Canada chose not to adopt an orphan drug policy) and 2012 (when Canada reversed its policy decision). Specifically, we looked at two dimensions of access to US-approved orphan drugs in Canada: (1) regulatory access; and (2) temporal access. Whereas only 63% of US-approved orphan drugs were granted regulatory approval in 1997, we found that regulatory access to US-approved orphan drugs in Canada increased to 74% between 1997 and 2012. However, temporal access to orphan drugs is slower in Canada: in a head-on comparison of 40 matched drugs, only two were submitted and four were approved first in Canada; moreover, the mean review time in Canada (423 days) was longer than that in the US (mean = 341 days), a statistically significant difference (t[39] = 2.04, p = 0.048). These results raise questions about what motivated Canada's apparent shift in orphan drug policy.

  4. The impact of the Cyanamid Canada Co. discharges to benthic invertebrates in the Welland River in Niagara falls, Canada.

    1993-06-01

    : In 1986, the International Joint Commission (IJC) recommended that the Niagara River watershed should be declared an Area of Concern (AOC). This IJC recommendation was ratified by the 4 signatories of the Great Lakes Water Quality Agreement. In order to delist an AOC, it is necessary to locate any areas of impairment within the watershed and carry out remediation projects that permit uses that were previously impaired. To this end we attempted to determine whether or not the sediments at 7 study sites near the Cyanamid Canada (Chemical) Co. were contaminated at levels that would result in the impairment of the natural biota which inhabit the watershed.The Cyanamid Canada (Chemical) Co. discharges ammonia wastes, cyanide, arsenic and a variety of heavy metals into treatment systems which ultimately discharge to the Welland River, the major Canadian tributary to the Niagara River. This portion of the Welland River near the factory was designated a Provincially significant (Class one) wetlands by the Ontario Ministry of Natural Resources. In 1986, the mean discharge to a creek from Cyanamid Canada Co. was 27,342 m(3) per day (MOE, 1987). Similar discharge volumes occurred in 1989. In 1991, the total discharge was 25,000 m(3) per day (MOE, 1991).The majority of the benthic invertebrates collected from the study area were pollution tolerant taxa (e.g., sludge worms constituted 68% of all the organisms collected). The lowest chironomid densities were observed at stations 1, 2, and 4, which were the only stations situated close to Cyanamid's discharge pipes. The absence, of clams and mayflies which burrow to greater depths than do chironomids and sludge worms, probably reflects the inability of the deeper dwelling burrowers to tolerate the contaminants which we recorded at these 3 stations. The absence of all crustaceans from these same 3 stations (stations 1, 2 and 4) when coupled with their low biotic diversity and the elevated heavy metal concentrations in the

    An overview of current activities in Canada is reported, including x-ray lithography studies based on laser plasma sources and x-ray mask development. In particular, the application of laser plasma sources for x-ray lithography is discussed, taking into account the industrial requirement and the present state of laser technology. The authors describe the development of silicon carbide membranes for x-ray lithography application. SiC films were prepared using either a 100 kHz plasma-enhanced chemical vapor deposition (PECVD) system or a laser ablation technique. These membranes have a relatively large diameter (> 1 in.) and a high optical transparency (> 50%). Experimental studies on stresses in tungsten films deposited with triode sputtering are reported.

    2004-07-01

    The construct of `neo-liberalism' well defines privatisation within a global convergence of educational policy discourses and practices. This study analyses initiatives for and processes of privatisation in Canadian education from K-12 to post-secondary levels. In considering how privatisation is affecting public education systems in Canada, the authors focus on the commodification and marketisation of education. They also examine issues of equity and the viability of universally accessible and publicly funded education systems. Finally, the study highlights two main interrelated trends: the intrusion of market discourse into education at all levels on one hand and on the other a growing tension between contrasting conceptions of education as a tradable commodity and as a social right.

    2016-08-01

    In the field of chronic disease prevention (CDP), collaborations between organizations provide a vital framework for intersectoral engagement and exchanges of knowledge, expertise and resources. However, little is known about how the structures of preventive health systems actually articulate with CDP capacity and outcomes. Drawing upon data from the Public Health Organizational Capacity Study - a repeat census of all public health organizations in Canada - we used social network analysis to map and examine interorganizational collaborative relationships in the Canadian preventive health system. The network of relationships obtained through our study shows that provincial boundaries remain a major factor influencing collaborative patterns. Not only are collaborations scarce on the interprovincial level but they are also mostly limited to links with federal and multi-provincial organizations. Given this finding, federal or multi-provincial organizations that occupy central bridging positions in the Canadian CDP collaborative structure should serve as key players for shaping CDP practices in the country.

    Indoor air and outdoor air concentration (I/O) ratio can be used to identify the origins of volatile organic compounds (VOCs). I/O ratios of 25 VOCs in Canada were estimated based on the data collected in various areas in Canada between September 2009 and December 2011. The indoor VOC data were extracted from the Canadian Health Measures Survey (CHMS). Outdoor VOC data were obtained from Canada's National Air Pollution Surveillance (NAPS) Network. The sampling locations covered nine areas in six provinces in Canada. Indoor air concentrations were found higher than outdoor air for all studied VOCs, except for carbon tetrachloride. Two different approaches were employed to estimate the I/O ratios; both approaches produced similar I/O values. The I/O ratios obtained from this study were similar to two other Canadian studies where indoor air and outdoor air of individual dwellings were measured. However, the I/O ratios found in Canada were higher than those in European cities and in two large USA cities, possibly due to the fact that the outdoor air concentrations recorded in the Canadian studies were lower. Possible source origins identified for the studied VOCs based on their I/O ratios were similar to those reported by others. In general, chlorinated hydrocarbons, short-chain (C5, C6) n-alkanes and benzene had significant outdoor sources, while long-chain (C10sbnd C12) n-alkanes, terpenes, naphthalene and styrene had significant indoor sources. The remaining VOCs had mixed indoor and outdoor sources.

    Full Text Available Abstract Background The presence of a fragility fracture is a major risk factor for osteoporosis, and should be an indicator for osteoporosis diagnosis and therapy. However, the extent to which patients who fracture are assessed and treated for osteoporosis is not clear. Methods We performed a review of the literature to identify the practice patterns in the diagnosis and treatment of osteoporosis in adults over the age of 40 who experience a fragility fracture in Canada. Searches were performed in MEDLINE (1966 to January 2, 2003 and CINAHL (1982 to February 1, 2003 databases. Results There is evidence of a care gap between the occurrence of a fragility fracture and the diagnosis and treatment of osteoporosis in Canada. The proportion of individuals with a fragility fracture who received an osteoporosis diagnostic test or physician diagnosis ranged from 1.7% to 50%. Therapies such as hormone replacement therapy, bisphosphonates or calcitonin were being prescribed to 5.2% to 37.5% of patients. Calcium and vitamin D supplement intake was variable, and ranged between 2.8% to 61.6% of patients. Conclusion Many Canadians who experience fragility fracture are not receiving osteoporosis management for the prevention of future fractures.

    Full Text Available This article analyses the capacity of Canadian federalism to articulate andaccommodate the dual and regionalist character defining Canada througha range of arguments and opinions both for and against that have been generatedboth within the Canadian Federation and abroad. From the standpointof the Quebec sovereignists, federalism is highly restrictive of the Quebecnation’s freedom to express itself, by itself, within the Canadian contextas well as within international ambits; for Quebec nationalists, the termQuebec “nation” implies—indeed, requires—a “Quebec state”. But, fromthe standpoint of the Quebec federalists (a good number of whom understandQuebec as a sociological and political nation, the future of Quebeclies with its membership of the Canadian Federation, however much this hasto recognise Quebec as a “differential society” within Canada, and howevermuch it has to ensure that Quebec will develop and promote its interests asa nation. For yet others, the decentralist character of Canadian federalism,and the extensive provisions for asymmetry built into the system, mean that Quebec is already perhaps the most powerful sub-national government inthe world, such that it already has the powers necessary to fulfil its nationaldestiny, within the federation. Opinion outside Quebec ranges from thosewho accept this view, and embrace asymmetry, to those who argue that Quebecis simply one of ten existing provinces, each of which is distinct, andwhich should all be treated as equals in accordance with the constitutionaland political framework.

    2016-12-01

    This study presents an analysis of the observed inter-annual variability and inter-decadal trends in river discharge across northern Canada for 1964-2013. The 42 rivers chosen for this study span a combined gauged area of 5.26 × 106 km2 and are selected based on data availability and quality, gauged area and record length. Inter-annual variability in river discharge is greatest for the eastern Arctic Ocean (coefficient of variation, CV = 16 %) due to the Caniapiscau River diversion into the La Grande Rivière system for enhanced hydropower production. Variability is lowest for the study area as a whole (CV = 7 %). Based on the Mann-Kendall test (MKT), no significant (p > 0.05) trend in annual discharge from 1964 to 2013 is observed in the Bering Sea, western Arctic Ocean, western Hudson and James Bay, and Labrador Sea; for northern Canada as a whole, however, a statistically significant (p < 0.05) decline of 102.8 km3 25 yr-1 in discharge occurs over the first half of the study period followed by a statistically significant (p < 0.05) increase of 208.8 km3 25 yr-1 in the latter half. Increasing (decreasing) trends in river discharge to the eastern Hudson and James Bay (eastern Arctic Ocean) are largely explained by the Caniapiscau diversion to the La Grande Rivière system. Strong regional variations in seasonal trends of river discharge are observed, with overall winter (summer) flows increasing (decreasing, with the exception of the most recent decade) partly due to flow regulation and storage for enhanced hydropower production along the Hudson and James Bay, the eastern Arctic Ocean and Labrador Sea. Flow regulation also suppresses the natural variability of river discharge, particularly during cold seasons.

    This historical study estimated the protective effects of a universally accessible, single-payer health care system versus a multi-payer system that leaves many uninsured or underinsured by comparing breast cancer care of women living in high poverty neighborhoods in Ontario or California between 1996 and 2011. Women in Canada experienced better care particularly as compared to women who were inadequately insured in the United States. Women in Canada were diagnosed earlier (rate ratio [RR] = 1.12) and enjoyed better access to breast conserving surgery (RR = 1.48), radiation (RR = 1.60) and hormone therapies (RR = 1.78). Women living in high poverty Canadian neighborhoods even experienced shorter waits for surgery (RR = 0.58) and radiation therapy (RR = 0.44) than did such women in the US. Consequently, women in Canada were much more likely to survive longer. Regression analyses indicated that health insurance could explain most of the better care and better outcomes in Canada. Over this study's 15-year timeframe 31,500 late diagnoses, 94,500 sub-optimum treatment plans and 103,500 early deaths were estimated in high poverty US neighborhoods due to relatively inadequate health insurance coverage. Implications for social work practice, including advocacy for future reforms of US health care are discussed.

    Regulatory requirements for renewable content in diesel fuel have been adopted in Canada. Fatty acid alkyl esters, that is, biodiesel, will likely be used to meet the regulations. However, the impacts on ambient atmospheric pollutant concentrations and human health outcomes associated with the use of biodiesel fuel blends in heavy duty diesel vehicles across Canada have not been evaluated. The objective of this study was to assess the potential human health implications of the widespread use of biodiesel in Canada compared to those from ultralow sulfur diesel (ULSD). The health impacts/benefits resulting from biodiesel use were determined with the Air Quality Benefits Assessment Tool, based on output from the AURAMS air quality modeling system and the MOBILE6.2C on-road vehicle emissions model. Scenarios included runs for ULSD and biodiesel blends with 5 and 20% of biodiesel by volume, and compared their use in 2006 and 2020. Although modeling and data limitations exist, the results of this study suggested that the use of biodiesel fuel blends compared to ULSD was expected to result in very minimal changes in air quality and health benefits/costs across Canada, and these were likely to diminish over time.

  17. Isotope paleohydrology at the northern Boreal treeline, Canada and Russia (paleohydrology climate change)

    Wolfe, B.B.

    1997-12-31

    A Canada-Russia international research project was established to better understand the relationship between the northern treeline region and climate change. The study involved the oxygen and carbon isotope analysis of lake sediment cores using several different sedimentological, biological and geochemical techniques. The study has provided an insight into Holocene paleohydrology and watershed carbon cycling in arctic Canada and Russia. Results showed that periods of treeline advance and climate warming in central Canada and central and eastern Russia were characterized by distinct changes in moisture conditions. During these intervals, summer relative humidity increased by 10 to 15 per cent in central Canada. Central Russia was also wetter, but a drier climate was associated with treeline advance in eastern Russia. Carbon isotope records have suggested that lake carbon reservoirs at boreal treeline were greatly influenced by catchment hydrology as well as soil and vegetation development. Nitrogen isotope composition of lacustrine bulk organic matter was also useful for determining nutrient dynamics in these watersheds. It was concluded that lake sediment organic isotope tracers are an effective approach for paleoenvironmental reconstruction.

    During the experiment, calculations were made of the mud-mineral equilibrium and studies were made of the x-ray diffractogram of the solid phases. Data on deviations from equilibriums and intensity of the normalized x-ray diffraction peaks were processed by the method of dispersion analysis. It was established that in addition to dissolving the quartz, formation of montmorillonite occurs, probably by forming transitional illite-montmorillonite interstratified layered structures. The reactions promote high pH values of the aqueous medium. The solubility of siderite to a considerable degree is determined by the reaction time and mineralization of the aqueous phase, and also the ratios of pH/mineralization, time/mineralization and pH/temperature/time. Despite the limitations associated with laboratory nature of the experiment, one can draw the conclusion that during development of the bituminous sands by the in situ method, processes of dissolving minerals are widespread.

    The interactions between land and atmosphere that occur as a result of agricultural practices in Canada are reviewed and analyzed. While some changes may be benign, or even beneficial to humans and plants, there is evidence to suggest that adverse effects are also occurring. The evidence suggests that these negative changes will continue to increase unless changes are made in the way we manage energy, food and fiber economics. Agriculture is a main source of greenhouse gases, accounting for 25 per cent of carbon dioxide, 50 per cent of methane, and 70 per cent of nitrous oxides released via human activity globally. Agriculture also accounts for more than 50 per cent of ammonia released into the air. The study describes various options available for increasing the efficiency of using agricultural resources. It also examines the feasibility of restoring organic carbon in the soil through conservation tillage and other means, thereby reducing atmospheric carbon dioxide. refs., tabs., figs.

    In partnership with the Young/Single Parent Support Network of Ottawa-Carleton and Timmin's Native Friendship Centre, the Canadian Institute of Child Health has completed a framework to reduce the rate of teen pregnancy in Canada. The final document is called Pro-Action, Postponement, and Preparation/Support: A Framework for Action to Reduce the Rate of Teen Pregnancy in Canada. The objectives were to learn what is currently being done and what needs to be done on this issue across the country, and to explore the potential role of projects funded by the federal Canada Action Program for Children (CAPC) and Canada Prenatal Nutrition Program (CPNP) in reducing the rate of teen pregnancy. Being an extremely complex and sensitive issue, the report was a culmination of a number of research methods: over 40 key informants from diverse backgrounds and expertise were interviewed to determine the scope of the problem and potential solutions; a detailed literature review identified existing date and documentation on the topic, using both Canadian and international studies; youth surveys and focus groups were conducted in both on-reserve Aboriginal communities and non-Aboriginal communities.

  13. Could European Governance Ideas Improve Federal-provincial Relations in Canada?

    Directory of Open Access Journals (Sweden)

    Wood, Donna E.

    2013-09-01

    Full Text Available Over the past seventeen years Canada has decentralized many social programmes, moving responsibility from the federal government to 13 provinces and territories through bilateral federal-provincial agreements. In contrast, the European Union (EU has moved in the opposite direction, building pan-European approaches and establishing new processes to facilitate multilateral collaboration among the 28 EU member states. This has been done through a new governance approach called the Open Method of Coordination (OMC. Using a detailed case study − employment policy − this paper explores whether Canada could learn from OMC governance ideas to re-build a pan-Canadian dimension to employment policy and improve the performance of its intergovernmental relations system. Concrete lessons for Canada to improve decentralized governance are suggested: consolidating the different bilateral agreements; using benchmarking instead of controls in fiscal transfers; undertaking research, analysis, and comparisons in order to facilitate mutual learning; revitalizing intergovernmental structures in light of devolution; and engaging social partners, civil society and other stakeholders. Post-devolution Canada is not doing badly in managing employment policy, but could do better. Looking to the EU for ideas on new ways to collaborate provides a chance for setting a forward looking agenda that could ultimately result not only in better labour market outcomes, but also improvements to one small part of Canada’s often fractious federation.

    This study evaluated the role of biotechnology in ensuring sustainable development in Canada. The report examined the opportunities and steps that need to be taken if Canadians decide to embrace biotechnology as a means of promoting sustainable development. Four trends were identified as enabling a biotechnology transition, notably (1) cellulosic ethanol production and biorefineries, (2) Canada's approach to eco-efficiency and persistent chemical contaminants, (3) community and industry-led initiatives for value-added uses of wastes and contaminated areas, and (4) the continued integration of science and technology applications. The report also reviewed recent activities and mandates undertaken by the Canadian government to promote biotechnology. Recommendations included taking a strategic approach to Biotechnology Sustainability and Canada's Future Economy (BSDE) with a focus on the implementation of advanced technologies. Canada will also need to recognize the interlocked nature of the economy and the environment and prepare to engage citizens and stakeholders in dialogue. It was concluded that governance for the adaptive management of BSDE needs to be strengthened by optimizing existing governance mechanisms.19 figs.

    2006-07-01

    The purpose of this study was to profile nutrition counseling strategies for eating disorders that English-speaking Canadian registered dietitians (RDs) use and to explore their educational needs in this area. A cross-sectional survey consisting of open- and closed-ended questions on nutrition counseling strategies was developed and administered via mail. Types of strategies included assessment, rapport-building, educational, and behavior-change strategies. Sixty-five of the 116 eligible RDs who were members of the Dietitians of Canada Eating Disorder Network responded to the survey. Descriptive statistics, chi(2), and Spearman correlation statistics were used. P values less than 0.05 were considered significant. Canadian RDs used strategies that were familiar and strategies they considered useful. Content-oriented or "doing" strategies were used more often than strategies that involved some process-oriented or "thinking" strategies. Reading and intuition were the most frequently reported learning routes. Seventy-one percent of respondents were dissatisfied with the educational opportunities available to RDs in this area in Canada. In Canada, both generalist RDs and specialist eating disorders RDs work with clients with eating disorders. In the absence of a formal nutrition counseling education program, there seems to be a reliance on informal learning routes such as reading or intuition, which may be suboptimal. To optimize eating disorders nutrition practice in Canada, formal coordinated programming that accounts for the educational needs of specialist RDs as well as generalist RDs is needed.

    2009-01-01

    The National Wildlife Refuge System has an active habitat restoration program and annually seeds thousands of hectares with native plant species. The noxious weed, Canada thistle (Cirsium arvense), plagues these restorations. This study evaluates planting methodology and seed mixes with the goal of recommending optimal methods to reduce infestation of noxious weeds, especially Canada thistle, in new restorations. Three planting methods (dormant season broadcast, growing season [summer] broadcast, and growing season [summer] drill) were fully crossed with three levels of seed diversity (10, 20, and 34 species [plus a fourth level, 58 species, on the three sites in Iowa]) in a completely randomized design replicated on nine sites in Minnesota and Iowa. The propagule bank of Canada thistle was evaluated at each site. Planting occurred in winter 2004 and spring-summer 2005. Here I report on results through summer 2007. None of the planting methods or seed mix diversities consistently resulted in reduced abundance of Canada thistle. Soil texture had the strongest influence; sites with greater proportions of clay had greater frequency and cover of Canada thistle than did sandy sites. At the Minnesota study sites, the dormant broadcast planting method combined with the highest seed diversity resulted in both the greatest cover of planted species as well as the greatest richness of planted species. At the Iowa sites, planted species richness was slightly greater in the summer drill plots, but cover of planted species was greatest in the dormant broadcast plots. Richness of planted species at the Iowa sites was maximized in the high diversity plots, with the extra-high diversity seed mix resulting in significantly lower species richness. Individual species responded to planting methods idiosyncratically, which suggests that particular species could be favored by tailoring planting methods to that species.

    2008-03-01

    Full Text Available The story of the growth of open source use in Canada has been far more a matter of evolution than revolution, so quiet in its pace that its progress has been difficult to measure. This has posed many challenges to Canadian open source advocates in their efforts to ensure that their country does not lag behind the rest of the world in understanding the social and business benefits open source provides. Perhaps some of the leading soldiers in the trenches might be our civil servants who protect the public purse. In addition to managing and minimizing the costs of delivering necessary services, public sector projects should also advance the social good through the delicate balance of transparency and efficiency.

    Emerging grids play a significant role in the computational, data, storage, and network requirements of high energy physics experiments coming online in the next few years. One such requirement, the bulk transfer of data over advanced high speed optical networks is necessary as such experiments are highly distributed with resources and participants from research laboratories and institutions spanning the globe. This trial at the iGrid 2002 conference attempts to stress the feasibility of high speed bulk data transfer over an end-to-end lightpath, a dedicated point-to-point optical link. Specifically, the objective was to transfer 1 TB of Monte Carlo data from TRIUMF in Vancouver, Canada, to CERN in Geneva, Switzerland. A rate equivalent to transferring a full CD of data every 8 s was achieved. (15 refs).

    Gerard Verzeni, former director of the dam safety & environment at Hydro-Quebec introduced the future directions of dam safety in Canada. New and numerous challenges are emerging for the dam safety community. Measurable effects of climate changes illustrate that hydraulic forecasts would change drastically. Loads with times and amplitudes which are different from the actual knowledge will apply on dams. The development of new types of dams using recent technologies raises several issues, for example the longevity of such installations. The installations are becoming old and soon will require complete renovation and update for regulation and standards compliance. Concrete dams already need efforts and investment to maintain then in a safe state. Various factors will influence these challenges such as human resources in the dam safe community. In these conditions, it is important that organizations like CDA play an important role in providing support and reference and in being a driver for the whole industry.

    This paper suggested that Canada can play a leading role in the development of hydrogen railways. Canadian scientists were among the first to test and develop the world's first hydrogen locomotive, and Canadian rail firms are now in a position to play a prominent role in the passenger hydrogen rail equipment market. A hydrogen railway will be built as part of Vancouver's 2010 winter olympics infrastructure. The Fraser Valley Heritage Railway Society is planning to use hydrogen to power vintage inter-urban trolley cars connecting Surrey communities. A Canadian manufactured hybrid locomotive will be modified to create the world's first hydrogen rail switch engine. It was concluded that hydrogen's storage capacity makes it an enabling technology for other other renewable energy technologies. Future hydrogen storage technologies will probably be hybridized with fuel cells in highly efficient applications. 1 ref.

  4. Distributive justice and infertility treatment in Canada.

    Science.gov (United States)

    Nisker, Jeff

    2008-05-01

    An exploration of distributive justice in Canadian infertility treatment requires the integration of ethical, clinical, and economic principles. In 1971, American philosopher John Rawls proposed a theoretical model for fair decision-making in which "rational" and "self-interested" citizens are behind a "veil of ignorance" with respect to both their own position and the position of other decision-makers. Rawls proposed that these self-interested decision-makers, fearing that they are among the least advantaged persons who could be affected by the decision, will agree only upon rules that encode equality of opportunity and that bestow the greatest benefit on the least advantaged citizens. Regarding health policy decision-making, Rawls' model is best illustrated by Canadian philosopher Warren Bourgeois in his panel of "volunteers." These rational and self-interested volunteers receive an amnestic drug that renders them unaware of their health, social, and financial position, but they know that they are representative of diverse spheres of citizens whose well-being will be affected by their decision. After describing fair decision-making, Bourgeois considers the lack of a distributive justice imperative in Canada's Assisted Human Reproduction Act, in contrast to legislation in European nations and Australia, summarizes the economic and clinical considerations that must be provided to the decision-makers behind the "veil of ignorance" for fair decisions to occur, and considers altruism in relation to equality of access. He concludes by noting that among countries with legislation governing assisted reproduction Canada is alone in having legislation that is void of distributive justice in providing access to clinically appropriate infertility care.

    The U.S. Geological Survey recently completed a geoscience-based assessment of undiscovered oil and gas resources of provinces within the Western Canada Sedimentary Basin. The Western Canada Sedimentary Basin primarily comprises the (1) Alberta Basin Province of Alberta, eastern British Columbia, and the southwestern Northwest Territories; (2) the Williston Basin Province of Saskatchewan, southeastern Alberta, and southern Manitoba; and (3) the Rocky Mountain Deformed Belt Province of western Alberta and eastern British Columbia. This report is part of the U.S. Geological Survey World Petroleum Resources Project assessment of priority geologic provinces of the world. The assessment was based on geoscience elements that define a total petroleum system (TPS) and associated assessment unit(s). These elements include petroleum source rocks (geochemical properties and petroleum generation, migration, and accumulation), reservoir description (reservoir presence, type, and quality), and petroleum traps (trap and seal types, and timing of trap and seal formation relative to petroleum migration). Using this framework, the Elk Point-Woodbend Composite TPS, Exshaw-Fernie-Mannville Composite TPS, and Middle through Upper Cretaceous Composite TPS were defined, and four conventional assessment units within the total petroleum systems were quantitatively assessed for undiscovered resources in the Western Canada Sedimentary Basin.

  6. Occurrence of arsenic contamination in Canada: sources, behavior and distribution.

    Wang, Suiling; Mulligan, Catherine N

    2006-08-01

    Recently there has been increasing anxieties concerning arsenic related problems. Occurrence of arsenic contamination has been reported worldwide. In Canada, the main natural arsenic sources are weathering and erosion of arsenic-containing rocks and soil, while tailings from historic and recent gold mine operations and wood preservative facilities are the principal anthropogenic sources. Across Canada, the 24-h average concentration of arsenic in the atmosphere is generally less than 0.3 microg/m3. Arsenic concentrations in natural uncontaminated soil and sediments range from 4 to 150 mg/kg. In uncontaminated surface and ground waters, the arsenic concentration ranges from 0.001 to 0.005 mg/L. As a result of anthropogenic inputs, elevated arsenic levels, above ten to thousand times the Interim Maximum Acceptable Concentration (IMAC), have been reported in air, soil and sediment, surface water and groundwater, and biota in several regions. Most arsenic is of toxic inorganic forms. It is critical to recognize that such contamination imposes serious harmful effects on various aquatic and terrestrial organisms and human health ultimately. Serious incidences of acute and chronic arsenic poisonings have been revealed. Through examination of the available literature, screening and selecting existing data, this paper provides an analysis of the currently available information on recognized problem areas, and an overview of current knowledge of the principal hydrogeochemical processes of arsenic transportation and transformation. However, a more detailed understanding of local sources of arsenic and mechanisms of arsenic release is required. More extensive studies will be required for building practical guidance on avoiding and reducing arsenic contamination. Bioremediation and hyperaccumulation are emerging innovative technologies for the remediation of arsenic contaminated sites. Natural attenuation may be utilized as a potential in situ remedial option. Further

    2008-01-01

    Full Text Available Abstract Background In response to a number of court challenges brought forth by Canadian patients who demonstrated that they benefited from the use of medicinal cannabis but remained vulnerable to arrest and persecution as a result of its status as a controlled substance, in 1999 Canada became the second nation in the world to initiate a centralized medicinal cannabis program. Over its six years of existence, this controversial program has been found unconstitutional by a number of courts, and has faced criticism from the medical establishment, law enforcement, as well as the patient/participants themselves. Methods This critical policy analysis is an evidence-based review of court decisions, government records, relevant studies and Access to Information Act data related to the three main facets of Health Canada's medicinal cannabis policy – the Marihuana Medical Access Division (MMAD; the Canadians Institute of Health Research Medical Marijuana Research Program; and the federal cannabis production and distribution program. This analysis also examines Canada's network of unregulated community-based dispensaries. Results There is a growing body of evidence that Health Canada's program is not meeting the needs of the nation's medical cannabis patient community and that the policies of the Marihuana Medical Access Division may be significantly limiting the potential individual and public health benefits achievable though the therapeutic use of cannabis. Canada's community-based dispensaries supply medical cannabis to a far greater number of patients than the MMAD, but their work is currently unregulated by any level of government, leaving these organizations and their clients vulnerable to arrest and prosecution. Conclusion Any future success will depend on the government's ability to better assess and address the needs and legitimate concerns of end-users of this program, to promote and fund an expanded clinical research agenda, and to work in

    In 1984 cannabis derivatives, in particular marijuana, hashish and liquid hashish, continued to be the most readily available drugs of abuse in Canada. Marijuana originating in Colombia decreased on the illicit marijuana market in Canada from an estimated 45 per cent in 1983 to 30 per cent in 1984, but it remained the largest source of marijuana supply. Marijuana originating in Thailand remained at approximately the same level (20 per cent) in 1984 as in 1983, while marijuana of Jamaican origin increased its share in the illicit market from 10 per cent in 1983 to 20 per cent in 1984. Approximately 10 per cent of marijuana on the illicit market originated in Canada, 10 per cent in Mexico, and 10 per cent in the United States of America. In 1984 an estimated 85 per cent of hashish on the illicit market in Canada originated in Lebanon (55 per cent in 1983), 10 per cent in India or Pakistan (31 per cent in 1983) and 5 per cent in Jamaica (2 per cent in 1983). Illicit shipments in tonnes of hashish originating in Lebanon made this the dominant source of supply of the drug. Liquid hashish originating in Jamaica shared 88 per cent of the illicit market of this drug in Canada during 1984, while 10 per cent of the drug originated in Lebanon and 2 per cent in Canada. In 1984 an estimated 40 per cent of smuggled marijuana entered the illicit market in Canada by air and approximately the same amount by sea, while 20 per cent was smuggled over land. During the same year, hashish was smuggled into Canada primarily by sea, while air accounted for 5 per cent and land for 1 per cent only. Liquid hashish, in contrast, entered Canada primarily by air, and only 9 per cent by land and 1 per cent by sea.

    Anti-microbial resistance can threaten health by limiting treatment options and increasing the risk of hospitalization and severity of infection. Companion animals can shed anti-microbial-resistant bacteria that may result in the exposure of other dogs and humans to anti-microbial-resistant genes. The prevalence of anti-microbial-resistant generic Escherichia coli in the faeces of dogs that visited dog parks in south-western Ontario was examined and risk factors for shedding anti-microbial-resistant generic E. coli identified. From May to August 2009, canine faecal samples were collected at ten dog parks in three cities in south-western Ontario, Canada. Owners completed a questionnaire related to pet characteristics and management factors including recent treatment with antibiotics. Faecal samples were collected from 251 dogs, and 189 surveys were completed. Generic E. coli was isolated from 237 of the faecal samples, and up to three isolates per sample were tested for anti-microbial susceptibility. Eighty-nine percent of isolates were pan-susceptible; 82.3% of dogs shed isolates that were pan-susceptible. Multiclass resistance was detected in 7.2% of the isolates from 10.1% of the dogs. Based on multilevel multivariable logistic regression, a risk factor for the shedding of generic E. coli resistant to ampicillin was attending dog day care. Risk factors for the shedding of E. coli resistant to at least one anti-microbial included attending dog day care and being a large mixed breed dog, whereas consumption of commercial dry and home cooked diets was protective factor. In a multilevel multivariable model for the shedding of multiclass-resistant E. coli, exposure to compost and being a large mixed breed dog were risk factors, while consumption of a commercial dry diet was a sparing factor. Pet dogs are a potential reservoir of anti-microbial-resistant generic E. coli; some dog characteristics and management factors are associated with the prevalence of anti

    Positron emission tomography (PET) imaging of brain amyloid beta is now clinically available in several countries including the United States and the United Kingdom, but not Canada. It has become an established technique in the field of neuroimaging of aging and dementia, with data incorporated in the new consensus guidelines for the diagnosis of Alzheimer disease and predementia Alzheimer's disease-related conditions. At this point, there are three US Food and Drug Administration- and European Union-approved tracers. Guided by appropriate use criteria developed in 2013 by the Alzheimer's Association and the Society of Nuclear Medicine and Molecular Imaging, the utility of amyloid imaging in medical practice is now supported by a growing body of research. In this paper, we aimed to provide an update on the 2012 Canadian consensus guidelines to dementia care practitioners on proper use of amyloid imaging. We also wished to generate momentum for the industry to submit a new drug proposal to Health Canada. A group of local, national, and international dementia experts and imaging specialists met to discuss scenarios in which amyloid PET could be used appropriately. Peer-reviewed and published literature between January 2004 and May 2015 was searched. Technical and regulatory considerations pertaining to Canada were considered. The results of a survey of current practices in Canadian dementia centers were considered. A set of specific clinical and research guidelines was agreed on that defines the types of patients and clinical circumstances in which amyloid PET could be used in Canada. Future research directions were also outlined, notably the importance of studies that would assess the pharmaco-economics of amyloid imaging.

    Full Text Available EnglishIn this exploratory study, we profile variations in home leaving, homereturning,and home staying behaviour among four ethnocultural groups in Canada -British, Chinese, Indian, and South European. Data collected in a 1999-2000survey of 1,907 young adults (ages 19-35 residing in the Vancouver area areused. Our principal foci are ethnocultural and gendered aspects of home leavingtrajectories, specifically: ages at home leaving and returning, and reasons forhome leaving, home returning and home staying. Special attention is paid toreturners/boomerangers, given an increasing overall trend in home returning inCanada. We find that: (a both ethnocultural origin and gender are importantdeterminants of home leaving trajectory, (b there is a distinct (but far from tidydifference between European-origin and Asian-origin groups in home leavingtrajectory, (c British-Canadians leave home at the youngest ages and Indo-Canadians at the oldest ages, (d the main reason for home leaving isindependence for British-Canadians; schooling for Chinese-Canadians, andmarriage for Indo-Canadians, (e among all four groups, home returners leavehome initially at younger ages and, with the exception of Indo-Canadian youngmen, who typically leave home for school, and (f gender differences in homeleaving trajectory are larger among the Chinese and Indo-Canadians than amongpersons of European origins. Overall, we conclude that the theorized trend of theindividualized family life course holds for only some ethnocultural groups inCanada. We conclude with suggestions for future research directions on thetopic of ethnicity and the home leaving life course transitions.FrenchDans cette étude préliminaire, nous donnons le profil de plusieurscomportements relatifs au fait de quitter la maison, d’y retourner et d’y rester dequatre groupes ethnoculturels au Canada, notamment les Britanniques, lesChinois, les Indiens et les ressortissants du sud de l’Europe.

  16. Averting Canada's water Armageddon

    2000-07-01

    Water conservation policies in Canada are examined in expectation of an imminent water crisis in the world, a crisis resulting from scarcity and aggravated by deteriorating quality. Despite Canada's seemingly abundant water resources, recent events, particularly in Ontario, give reason to be concerned that the province that spawned the common sense revolution is quite capable of sparking a national water crisis all by itself. Significant drop in water levels in the Great Lakes, the Walkerton debacle of E. coli contamination of the water supply which resulted in at least seven deaths and over 1000 serious illnesses, the massive housing development proposal that threatens the area known as the Oak Ridges Moraine, a source of groundwater that supplies much of southern Ontario, and the government's action (later reversed) to issue a licence to an Ontario company to withdraw 600 million litres of water annually from Lake Superior for export to Asia, are some of the examples cited as indicators of the fragile state of water supply and the many threats posed to both water quantity and quality. Having examined some of the dangers facing our water supply, the author provides some suggestions of how to resolve first, the issue of overlapping jurisdictions and the tangled constitutional framework for managing the nation's water resources and second, some steps that should be taken to stop mega-diversions and mega-consumptive use, and to make certain that even the most modest project in this area proceeds only after the fullest environmental and public scrutiny. Provincial laws must also link land use changes and development to protection of provincial waters, proactively encourage water conservation, repair past mistakes by requiring the restoration and enhancement of the water regime where it has been damaged by human activity, establish a water superfund to pay for effective water conservation planning, and recognize the public's right to a significant

    Full Text Available National governments are keenly aware of the need for investment in space. Canada, as a formal cooperating state in the European Space Agency (ESA, and Germany, as a leading member state of ESA, are interlinked in Europe’s space endeavours. Beyond ESA, Germany and Canada additionally have a strong history of bilateral cooperation on a range of space projects. This paper discusses the novel interdependencies between clear national and now supranational space policies, using the examples of the Canada-European Union (EU Comprehensive Economic and Trade Agreement (CETA. The agreement covers most aspects of the EU-Canada bilateral economic relationship and includes space. The paper focuses on international space policies, strategic bilateral co-operation, and technical accomplishments. It takes a closer look at German-Canadian collaboration in space programs and offers some reflection on the effect of both the EU and ESA’S transatlantic involvement in space.
