  2. The influence of coyotes on an urban Canada goose population in the Chicago metropolitan area

    Energy Technology Data Exchange (ETDEWEB)

    Brown, Justin L.; /Ohio State U.

    2007-01-01

    Canada geese (Branta canadensis) have become common in many urban areas, often creating nuisance problems for human residents. The presence of urban geese has raised concerns about the spread of disease, increased erosion, excessive noise, eutrophication of waterways, and general nuisance problems. Goose populations have grown due to an increase in urbanization resulting in an abundance of high quality food (urban grass) and suitable nesting sites, as well as a decrease in some predators. I monitored nest predation in the Chicago suburbs during the 2004 and 2005 nesting seasons using 3 nest monitoring techniques to identify predators: video cameras, plasticine eggs, and sign from nest using a classification tree analysis. Of 58 nests monitored in 2004 and 286 in 2005, only raccoons (Procyon lotor) and coyotes (Canis latrans) were identified as nest predators. Raccoons were responsible for 22-25% of depredated nests, but were rarely capable of depredating nests that were actively defended by a goose. Coyotes were responsible for 75-78% of all Canada goose nest depredation and were documented killing one adult goose and feeding on several others. The coyote is a top-level predator that had increased in many metropolitan areas in recent years. To determine if coyotes were actively hunting geese or eggs during the nesting season, I analyzed coyote habitat selection between nesting and pre-nesting or post-nesting seasons. Coyote home ranges (95% Minimum Convex Polygon) were calculated for 19 coyotes to examine third order habitat selection related to goose nest abundance. A 100 m buffer (buffer habitat) was created and centered on each waterway edge and contained 90% of all nests. Coyotes showed selection for habitats during all seasons. Buffer habitat was the top ranked habitat in both pre-nesting and nesting seasons, but dropped to third ranked in post-nesting season. Habitat selection across seasons was compared using a repeated measures MANOVA. Habitat selection

    1993-01-01

    The aim of the thesis was to document patterns in breeding and migration in Swedish Canada geese Branta canadensis, to explain these against the genetic and historical background of the population, and to test predictions of hypotheses pertaining to parental investment. The Canada goose population in Sweden was founded by the introduction of a few individuals in the 1930's. DNA fingerprint similarity between geese breeding in Sweden was on average at the same level as between inbred close rel...

    2016-01-01

    The last comprehensive nest survival study of the breeding giant Canada goose (Branta canadensis maxima) population in Iowa, USA, was conducted >30 years ago during a period of population recovery, during which available nesting habitat consisted primarily of artificial nest structures. Currently, Iowa's resident goose population is stable and nests in a variety of habitats. We analyzed the effects of available habitat on nest survival and how nest survival rates compared with those of the expanding goose population studied previously to better understand how to maintain a sustainable Canada goose population in Iowa. We documented Canada goose nest survival at rural wetland sites in north-central Iowa. We monitored 121 nests in 2013 and 149 nests in 2014 at 5 Wildlife Management Areas (WMAs) with various nesting habitats, including islands, muskrat (Ondatra zibethicus) houses, and elevated nest structures. We estimated daily nest-survival rate using the nest survival model in Program MARK. Survival was influenced by year, site, stage, presence of a camera, nest age, and an interaction between nest age and stage. Nest success rates for the 28-day incubation period by site and year combination ranged from 0.10 to 0.84. Nest survival was greatest at sites with nest structures (β = 17.34). Nest survival was negatively affected by lowered water levels at Rice Lake WMA (2013 β = −0.77, nest age β = −0.07). Timing of water-level drawdowns for shallow lake restorations may influence nest survival rates.

  6. Arctic foxes, lemmings, and canada goose nest survival at cape Churchill, Manitoba

    Science.gov (United States)

    Reiter, M.E.; Andersen, D.E.

    2011-01-01

    We examined factors influencing Canada Goose (Branta canadensis interior) annual nest success, including the relative abundance of collared lemmings (Dicrostonyx richardsoni), arctic fox (Alopex lagopus) den occupancy, nest density, and spring phenology using data collected during annual Canada Goose breeding area surveys at Cape Churchill, Manitoba. Nest density and arctic fox den occupancy strongly influenced Canada Goose nest success. High nest density resulted in higher nest success and high den occupancy reduced nest success. Nest success was not influenced by lemming abundance in the current or previous year as predicted by the "bird-lemming" hypothesis. Reducing arctic fox abundance through targeted management increased nest survival of Canada Geese; a result that further emphasizes the importance of arctic fox as nest predators in this system. The spatial distribution of nest predators, at least for dispersed-nesting geese, may be most important for nest survival, regardless of the abundance of small mammals in the local ecosystem. Further understanding of the factors influencing the magnitude and variance in arctic fox abundance in this region, and the spatial scale at which these factors are realized, is necessary to fully explain predator-prey-alternative prey dynamics in this system. ?? 2011 by the Wilson Ornithological Society.

    Rickard, W.H.; Eberhardt, L.E.

    1990-01-01

    90 Sr was measured in eggshells from Canada geese (Branta canadensis moffitti) that nested on Columbia River islands up- and downstream from deactivated plutonium production reactors on the U.S. Department of Energy's Hanford Site in southeastern Washington. We also measured 90 Sr in wing bones of goose carcasses. Background levels of 90 Sr were based on eggshells collected on an island upstream of the reactors. A few eggshells collected from nests on a single island downstream of the reactors had slightly higher than background levels of 90 Sr. This may have resulted from geese eating shoreline plants or crops irrigated with Columbia River water that contained 90 Sr released into the river through groundwater seepage

    1. Techniques are described for the cultural isolation of trypanosomes from avian bone marrow obtained from living birds or at autopsy. A new medium SNB-9 (saline-neopeptone-blood) is described. In addition to being a good medium for growing avian trypanosomes, it is excellent for growing trypanosomes of amphibians and mammals. 2. Evidence is presented demonstrating the superiority of (a) cultures over stained smears for detecting the presence of trypanosomes in the Canada goose, and (b) bone marrow over heart blood of this species as a source of trypanosomes for culture. 3. In April 1952, from cultures of bone marrow collected at autopsy it was demonstrated that trypanosome infection occurred in 33 (40.2%) of 82 Canada geese from the Pea Island National Wildlife Refuge. On February 17, 1953, cultures of bone marrow obtained from living birds revealed presence of trypanosomes in 12 (20.7%) of 58 geese from the same refuge. On February 26, 1953, by employing the latter method, 9 (20.4%) of 44 geese from Blackwater National Wildlife Refuge were shown to harbor the parasites. In another survey ninety-two geese from seven national wildlife refuges subjected to the biopsy technique showed evidence of infection in 13 (14.1 %) birds and indicated that trypanosome infection is widely distributed in this host.

    1980-01-01

    The western Canada goose (Branta canadensis moffitti) was divided into a Rocky Mountain population (RMP) and a Pacific population (PP) on the basis of band recovery patterns examined in this study and recovery data from other investigators. Habitat information obtained from nine cooperating wildlife agencies within the RMP's range provided a base line for evaluating future changes in nesting, molting, and wintering areas. The habitat inventory indicated that none of the seasonal habitats were currently limiting the size of the RMP. The RMP's range is divided into 15 reference areas and these are briefly described. Past studies of Canada geese in the Intermountain Region are reviewed. Topics covered in the discussion of breeding biology are nesting chronology, spring population composition, breeding age, clutch size, nesting success. artificial nesting structures, and gosling survival. Much of the mortality of Canada geese occurs before the birds are fledged. Man-made nesting structures reduce losses during incubation. but research is needed on the relations between brooding sites and gosling survival. Some western Canada geese, mainly prebreeders and unsuccessful nesters, make molt migrations to and from molting areas during and after the brood-rearing season. More than half of these molt-migrants are yearlings too young to nest; there are indications that even some successful nesters leave nesting areas to molt before the fledging of their offspring. Geese 2 years old or older may serve as guides to traditional molting areas for the first-time migrants (i.e., yearlings). Lack of disturbance appears to influence selection of specific molting areas within the nesting range of moffitti, whereas movements of molters out of the Intermountain Region may be related to the evolution of this subspecies. Apparently. molters of both the PP and RMP that leave the Region go to the Northwest Territories of Canada. Although the taxonomic status of moffitti as related to the

    Sound decisions on control actions for established invasive alien species (IAS) require information on ecological as well as socio-economic impact of the species and of its management. Cost-benefit analysis provides part of this information, yet has received relatively little attention in the scientific literature on IAS. We apply a bio-economic model in a cost-benefit analysis framework to greater Canada goose Branta canadensis , an IAS with documented social, economic and ecological impacts in Flanders (northern Belgium). We compared a business as usual (BAU) scenario which involved non-coordinated hunting and egg destruction with an enhanced scenario based on a continuation of these activities but supplemented with coordinated capture of moulting birds. To assess population growth under the BAU scenario we fitted a logistic growth model to the observed pre-moult capture population. Projected damage costs included water eutrophication and damage to cultivated grasslands and were calculated for all scenarios. Management costs of the moult captures were based on a representative average of the actual cost of planning and executing moult captures. Comparing the scenarios with different capture rates, different costs for eutrophication and various discount rates, showed avoided damage costs were in the range of 21.15 M€ to 45.82 M€ under the moult capture scenario. The lowest value for the avoided costs applied to the scenario where we lowered the capture rate by 10%. The highest value occurred in the scenario where we lowered the real discount rate from 4% to 2.5%. The reduction in damage costs always outweighed the additional management costs of moult captures. Therefore, additional coordinated moult captures could be applied to limit the negative economic impact of greater Canada goose at a regional scale. We further discuss the strengths and weaknesses of our approach and its potential application to other IAS.

    The issue of food insecurity affects millions of people in the United States every year. Often these people rely on soup kitchens, food banks, and shelters for proper meals, and these organizations often depend on donations to meet needs. One of the most limited food resources is meat. To help alleviate this problem, the U.S. Department of Agriculture Wildlife Services donates more than 60 tons of wild game (deer, moose, feral hogs, goats, geese, and ducks) to a variety of charitable organizations each year. Although commercially produced meat routinely undergoes screening for contaminants, potential exposure to environmental contaminants from eating wild game is not well characterized. In this study, the concentration of 17 contaminants of concern in the breast meat of wild geese was examined. These concentrations were then used in a probabilistic model to estimate potential risk associated with consumption of this meat. Based on model predictions, more than 99 % of all adults were below exposure limits for all of the compounds tested. For all consumer age classes modeled, consumption of wild goose meat may expose a small fraction of these populations to levels of lead higher than the recommended exposure limits. Similarly, mercury exposure was predicted to be higher than the recommended limits when the meat was served as steaks. This information about concentrations of contaminants of concern in goose meat and potential exposures associated with meat consumption based on probabilistic models will enable others to make informed decisions about the risks associated with the consumption of wild meat.

    The glycoprotein (G) gene sequences of avian metapneumovirus (aMPV) subtypes A, B, C, and D are variable in size and number of nucleotides. The G gene of early U.S. turkey isolates of aMPV-C have been reported to be 1798 nucleotides (nt) (585 aa) in length, whereas the G genes of more recent turkey isolates have been reported to be 783 nucleotides. In some studies, the G gene of aMPV-C turkey isolates was found to be truncated to a smaller G gene of 783 nt (261 aa) upon serial passages in Vero cells. This is believed to be due to the deletion of 1015 nt near the end of the open reading frame. The purpose of this study was to determine variation, if any, in the G gene of an aMPV-C isolated from a wild bird (Canada goose [Branta canadensis]) following serial passages in Vero cells. No size variation was observed for up to 50 passages, except for a few amino acid changes in the extracellular domain at the 50th passage level. The G gene of this wild bird isolate appears to be unique from subtype C metapneumoviruses of turkeys.

    Plasma glucose, free fatty acid and uric acid levels were measured in lead-poisoned Canada geese (Branta canadensis). Although plasma glucose levels were only slightly elevated, uric acid was significantly higher and free fatty acids were significantly lower. Altered plasma levels were attributed to increased protein catabolism and renal dysfunction. Plasma level of growth hormone and prolactin was assessed by radioimmunoassay. Growth hormone remained unchanged while prolactin was unusually high. The increased prolactin levels may reflect an effort to stabilize free fatty acids. 30 references, 1 figure, 2 tables

    Objective: To determine the current status of research experience in psychiatry residency programs across Canada. Method: Coordinators of Psychiatric Education (COPE) resident representatives from all 17 psychiatry residency programs in Canada were asked to complete a survey regarding research training requirements in their programs. Results: Among the 17 COPE representatives, 15 completed the survey, representing 88% of the Canadian medical schools that have a psychiatry residency program. Among the 15 programs, 11 (73%) require residents to conduct a scholarly activity to complete residency. Some of these programs incorporated such a requirement in the past 5 years. Ten respondents (67%) reported availability of official policy and (or) guidelines on resident research requirements. Among the 11 programs that have a research requirement, 10 (91%) require residents to complete 1 scholarly activity; 1 requires completion of 2 scholarly activities. Eight (53%) residency programs reported having a separate research track. All of the programs have a research coordinator and 14 (93%) programs provide protected time to residents for conducting research. The 3 most common types of scholarly activities that qualify for the mandatory research requirement are a full independent project (10 programs), a quality improvement project (8 programs), and assisting in a faculty project (8 programs). Six programs expect their residents to present their final work in a departmental forum. None of the residency programs require publication of residents’ final work. Conclusions: The current status of the research experience during psychiatry residency in Canada is encouraging but there is heterogeneity across the programs. PMID:25565474

    1991-04-01

    Overall, the nesting population of Great Basin Canada geese (Branta canadensis moffitti) on the Hanford Site in southcentral Washington State is doing well and appears to be increasing. The average annual total nests for the period 1981 through 1990 was 215 nests, which is slightly above the average reported for the period 1950 through 1970. The nesting population has shifted its nucleus from upriver islands (1--10) to the lower river islands (11--20) with over 70% of the present-day nesting occurring on Islands 17, 18, 19, 20. The annual percent-successful nests from 1981 through 1990 was 80%. This is above the 71% reported for 1950 to 1970, but is below the 82% reported for 1971 to 1980. Average annual clutch size for 1981 to 1990 was 6.05, which is above the 1971-to-1980 average of 5.6 and the 1950-to-70 average of 5.5. Next desertions for 1981 to 1990 averaged 8%. This rate is well below the 14% reported for 1950 to 1970. Predators were responsible for an annual predation rate of 9% from 1981 to 1990. This is below the 1950-to-1970 annual average predation rate of 14%. Flooding losses to nests were low during the 1980s, except for 1989 and 1990 when 6% and 9% of the total nests, respectively, were destroyed by flooding. 9 refs., 4 figs., 1 tab

    Toxoplasma gondii isolates can be grouped into 3 genetic lineages. Type I isolates are considered virulent to outbred mice, whereas Type II and III isolates are not. In the present report, viable T. gondii was isolated for the first time from striped skunk (Mephitis mephitis), Canada goose (Branta canadensis), and black-winged lory (Eos cyanogenia). For the isolation of T. gondii, tissues were bioassayed in mice, and genotyping was based on the SAG2 locus. Toxoplasma gondii was isolated from 3 of 6 skunks, 1 of 4 Canada geese, and 2 of 2 feral cats (Felis catus) from Mississippi. All donor animals were asymptomatic. Viable T. gondii was also isolated from 5 of 5 lories that had died of acute toxoplasmosis in an aviary in South Carolina. Genotypes of T. gondii isolates were Type III (all skunks, lories, and the goose) and Type II (both cats). All 5 Type III isolates from birds and 2 of the 3 isolates from skunks were mouse virulent.

    The integration of simulation into residency programs has been slower in obstetrics and gynaecology than in other surgical specialties. The goal of this study was to evaluate the current use of simulation in obstetrics and gynaecology residency programs in Canada. A 19-question survey was developed and distributed to all 16 active and accredited obstetrics and gynaecology residency programs in Canada. The survey was sent to program directors initially, but on occasion was redirected to other faculty members involved in resident education or to senior residents. Survey responses were collected over an 18-month period. Twelve programs responded to the survey (11 complete responses). Eleven programs (92%) reported introducing an obstetrics and gynaecology simulation curriculum into their residency education. All respondents (100%) had access to a simulation centre. Simulation was used to teach various obstetrical and gynaecological skills using different simulation modalities. Barriers to simulation integration were primarily the costs of equipment and space and the need to ensure dedicated time for residents and educators. The majority of programs indicated that it was a priority for them to enhance their simulation curriculum and transition to competency-based resident assessment. Simulation training has increased in obstetrics and gynaecology residency programs. The development of formal simulation curricula for use in obstetrics and gynaecology resident education is in early development. A standardized national simulation curriculum would help facilitate the integration of simulation into obstetrics and gynaecology resident education and aid in the shift to competency-based resident assessment. Obstetrics and gynaecology residency programs need national collaboration (between centres and specialties) to develop a standardized simulation curriculum for use in obstetrics and gynaecology residency programs in Canada.

  1. The resident's view of residency training in Canada.

    Fish, D G

    1966-04-09

    In the view of residents in their last year of specialty training, the Fellowship is now becoming the operative standard for obtaining hospital privileges in urban centres and they felt that this implied that the two standards, the Certificate and the Fellowship of the Royal College, were not achieving the purpose for which they were designed. Although 80% of the residents intended to write the Fellowship, few viewed a year in a basic science department or in research as of intrinsic value in terms of their future practice.The examinations of the Royal College were the subject of criticism, most residents feeling that the examinations did not test the knowledge and ability gained in training. Most expressed a desire for ongoing evaluation during the training period.Service responsibilities were generally regarded as too heavy.Despite the criticism of both training and examination, most residents felt that their training had provided them with the experience and background they needed to practise as specialists.

    2016-01-01

    Attrition rates in general surgery training are higher than other surgical disciplines. We sought to determine the prevalence with which Canadian general surgery residents consider leaving their training and the contributing factors. An anonymous survey was administered to all general surgery residents in Canada. Responses from residents who considered leaving their training were assessed for importance of contributing factors. The study was conducted at the Royal University Hospital, University of Saskatchewan, Saskatoon, Saskatchewan, Canada, a tertiary academic center. The response rate was approximately 34.0%. A minority (32.0%) reported very seriously or somewhat seriously considering leaving their training, whereas 35.2% casually considered doing so. Poor work-life balance in residency (38.9%) was the single-most important factor, whereas concern about future unemployment (16.7%) and poor future quality of life (15.7%) were next. Enjoyment of work (41.7%) was the most frequent mitigating factor. Harassment and intimidation were reported factors in 16.7%. On analysis, only intention to practice in a nonacademic setting approached significant association with thoughts of leaving (odds ratio = 1.92, CI = 0.99-3.74, p = 0.052). There was no association with sex, program, postgraduate year, relationship status, or subspecialty interest. There was a nonsignificant trend toward more thoughts of leaving with older age. Canadian general surgery residents appear less likely to seriously consider quitting than their American counterparts. Poor work-life balance in residency, fear of future unemployment, and anticipated poor future quality of life are significant contributors to thoughts of quitting. Efforts to educate prospective residents about the reality of the surgical lifestyle, and to assist residents in securing employment, may improve completion rates.

    There is limited research on why females do or do not choose a career in urology. Considering the increasing proportion of female medical students, we assessed for trends in female applicants to urology programs in Canada and their post-residency career choices. Data from the Canadian Residency Matching Service (CaRMS) was used (1998-2015). Trends in the proportions of females applying and matching to surgical subspecialties, and applying and matching to urology were computed. Surveys were sent to urology program directors to assess female residents' chosen career paths over the last decade. A significant increasing trend in the proportion of females applying to urology as their first choice program was found (0.19 in 1998-99 to 0.27 in 2012-15; p=0.04). An increasing trend in the proportion of females successfully matching to urology was found, although it was not statistically significant (0.13 in 1998-99 to 0.24 in 2012-15; p=0.07). This was in keeping with the trends found for surgical programs overall. Female graduates choose a variety of career paths with urogynecology being the most common fellowship (26%). The last two decades has seen an increase in the proportion of female students applying to urology in Canada. Female urology graduates pursue a variety of career paths. It remains imperative that both female and male medical students have early exposure and education about our subspecialty to ensure we continue to recruit the most talented candidates.

    Shallow lakes are dominant features in subarctic and Arctic landscapes and are responsive to multiple stressors, which can lead to rapid changes in limnological regimes with consequences for aquatic resources. We address this theme in the coastal tundra region of Wapusk National Park, western Hudson Bay Lowlands (Canada), where climate has warmed during the past century and the Lesser Snow Goose (LSG; Chen caerulescens caerulescens) population has grown rapidly during the past ∽40 years. Integration of limnological and paleolimnological analyses documents profound responses of productivity, nutrient cycling, and aquatic habitat to warming at three ponds ("WAP 12", "WAP 20", and "WAP 21″), and to LSG disturbance at the two ponds located in an active nesting area (WAP 20, WAP 21). Based on multiparameter analysis of (210)Pb-dated sediment records from all three ponds, a regime shift occurred between 1875 and 1900 CE marked by a transition from low productivity, turbid, and nutrient-poor conditions of the Little Ice Age to conditions of higher productivity, lower nitrogen availability, and the development of benthic biofilm habitat as a result of climate warming. Beginning in the mid-1970s, sediment records from WAP 20 and WAP 21 reveal a second regime shift characterized by accelerated productivity and increased nitrogen availability. Coupled with 3 years of limnological data, results suggest that increased productivity at WAP 20 and WAP 21 led to atmospheric CO2 invasion to meet algal photosynthetic demand. This limnological regime shift is attributed to an increase in the supply of catchment-derived nutrients from the arrival of LSG and their subsequent disturbance to the landscape. Collectively, findings discriminate the consequences of warming and LSG disturbance on tundra ponds from which we identify a suite of sensitive limnological and paleolimnological measures that can be utilized to inform aquatic ecosystem monitoring.

    To investigate the usage and perceived usefulness of new media for educating urology residents in Canada and Germany. We designed an 11-item online survey to assess the use and perceived usefulness of new media for education. We performed a comparative analysis. The survey was distributed via e-mail to 143 Canadian and 721 German urology residents. The survey included 58 urology residents from Canada and 170 from Germany. A total of 58 residents from Canada (41% response rate) and 170 from Germany (24% response rate) responded to this survey. Residents spent 45% of their education time on new media. The Internet was used by 91% (n = 208) of the residents for professional education purposes, with a median time of 270 minutes (interquartile range [IQR]: 114-540) per month. Apps were used by 54% (n = 118) of the residents, with a median time of 101 minutes (IQR: 45-293) per month. A total of 23% (n = 47) of the residents used social media (SoMe) for education, with a median time of 90 minutes (IQR: 53-80) per month. In all, 100% (n = 228) rated the Internet, 76% (n = 173) apps, and 43% (n = 97) SoMe as being useful for professional education purposes. A total of 90% (n = 205) watched medical videos for education, and 89% (n = 203) of these videos were on surgical procedures. Canadian urology residents used more new media sources for professional education than did the Germans (58% vs. 41%, p media was higher among Canadian residents for the Internet (p media play a dominant role in the education of urology residents. The primary source for personal education in urology is the Internet.

    To describe the postgraduate medical education (PGME) examination outcomes and work locations of international medical graduates (IMGs); and to identify differences between Canadians studying abroad (CSAs) and non-CSAs. Cohort study using data from the National IMG Database and Scott's Medical Database. Canada. All IMGs who had first entered a family medicine residency program between 2005 and 2009, with the exclusion of US graduates, visa trainees, and fellowship trainees. We examined 4 outcomes: passing the Medical Council of Canada Qualifying Examination Part 2 (MCCQE2), obtaining Certification in Family Medicine (CCFP), working in Canada within 2 years of completing PGME training, and working in Canada in 2015. Of the 876 residents in the study, 96.1% passed the MCCQE2, 78.1% obtained a specialty designation, 37.7% worked in Canada within 2 years after their PGME, and 91.2% worked in Canada in 2015. Older graduates were more likely (odds ratio [OR] = 3.45; 95% CI 1.52 to 7.69) than recent graduates were to pass the MCCQE2, and residents who participated in a skills assessment program before their PGME training were more likely (OR = 9.60; 95% CI 1.29 to 71.63) than those who had not were to pass the MCCQE2. Women were more likely (OR = 1.67; 95% CI 1.20 to 2.33) to obtain a specialty designation than men were. Recent graduates were more likely (OR = 1.36; 95% CI 1.03 to 1.79) than older graduates were to work in Canada following training. Residents who were eligible for a full licence were more likely (OR = 3.72; 95% CI 2.30 to 5.99) to work in Canada in 2015 than those who were not eligible for a full licence were. While most IMGs who entered the family medicine PGME program passed the MCCQE2, 1 in 5 did not obtain Certification. Most IMG residents remain in Canada. Canadians studying abroad and non-CSA IMGs share similar examination success rates and retention rates. Copyright© the College of Family Physicians of Canada.

    Early naturalists exploring western Alaska were intrigued to find a stocky, blue-gray species of coastal goose unique to that area and nearby Russia. As E. W. Nelson (1887) wrote, "Among the various species of birds more or less peculiar to Alaska this goose is perhaps the most noteworthy." The Emperor Goose nests in the extensive coastal salt marsh habitats of arctic and sub-arctic Alaska and Russia and winters primarily on coastal beaches along ice-free areas of the Aleutian Islands and the Alaska Peninsula. Locally known as the "Beach Goose" from its habit of roosting and feeding near the waters' edge, the diet of this species consists largely of clams, mussels, and algae when wintering and staging in marine and estuarine habitats. When nesting in terrestrial habitats, it eats mostly roots, bulbs, and shoots of vegetation. Although the breeding biology and habitat requirements of this goose have been examined in detail, mostly on the Yukon-Kuskokwim Delta (Y-K Delta) of Alaska, there have been no intensive studies of its wintering or staging biology. Recent studies of migration have confirmed pathways and timing between the Y-K Delta and staging areas on the Alaska Peninsula and wintering areas largely on the Aleutian Islands (Hupp et al. 2007). Observations of substantial molt migrations to the Chukotka Peninsula in eastern Russia (Hupp et al. 2007) suggest a possible change in distribution, or at least a clarification, and raise the possibility of harvest mortality on both continents. Alaska's Emperor Goose population declined precipitously from 139,000 in 1964 to 42,000 in 1986, although its numbers have recovered slightly since then (Fischer et al. 2008). The factors responsible for this quick decline and slow recovery remain poorly known. Hunting, especially subsistence hunting by Native Americans, is probably a factor (Hupp et al. 2008b); coastal oil pollution could also be reducing the survival of overwintering individuals (Byrd et al. 1995); and

    2008-01-01

    INTRODUCTION There is a significant overlap between paediatrics and otolaryngology relating to clinical practice of the two specialties. A lack of cross-training has been identified in previous studies, but the specifics have not been established. The present study was directed at paediatricians in Canada, and examined the need for mandatory otolaryngology training during paediatric residency. METHODS Surveys were mailed out to paediatricians in Canada who had completed residency within the past 20 years. Guidelines for the mailing procedure were regulated by the Royal College of Physicians and Surgeons of Canada. A cover letter, survey form and return envelope were included in the package. Data were tabulated and described using descriptive statistics. RESULTS Six hundred sixty-six surveys were mailed; the response rate was 48%. Seventy-three per cent of paediatricians indicated that otolaryngology training should be mandatory during paediatric residency. Seventy-nine per cent of general paediatricians and 68% of subspecialists also believed that it should be mandatory training. Seventy per cent of paediatricians indicated that clinical experience was the best format for otolaryngology training, the other options being lectures or rotations. Postgraduate year 2 was the most preferred year for this training. For paediatricians who indicated mandatory training, 45% indicated that it could not replace something else, 38% said that it could replace another experience and the remainder were undecided. The respondents provided helpful commentary. INTERPRETATION The majority of surveyed paediatricians in Canada believe that otolaryngology training should be mandatory during paediatric residency. There was also a general consensus relating to the format (clinical experience) and the duration (two to four weeks) of the training. PMID:19436427

    Full Text Available Abstract Background Currently, there are more residents enrolled in cardiology training programs in Canada than in immunology, pharmacology, rheumatology, infectious diseases, geriatrics and endocrinology combined. There is no published data regarding the proportion of Canadian internal medicine residents applying to the various subspecialties, or the factors that residents consider important when deciding which subspecialty to pursue. To address the concern about physician imbalances in internal medicine subspecialties, we need to examine the factors that motivate residents when making career decisions. Methods In this two-phase study, Canadian internal medicine residents participating in the post graduate year 4 (PGY4 subspecialty match were invited to participate in a web-based survey and focus group discussions. The focus group discussions were based on issues identified from the survey results. Analysis of focus group transcripts grew on grounded theory. Results 110 PGY3 residents participating in the PGY4 subspecialty match from 10 participating Canadian universities participated in the web-based survey (54% response rate. 22 residents from 3 different training programs participated in 4 focus groups held across Canada. Our study found that residents are choosing careers that provide intellectual stimulation, are consistent with their personality, and that provide a challenge in diagnosis. From our focus group discussions it appears that lifestyle, role models, mentorship and the experience of the resident with the specialty appear to be equally important in career decisions. Males are more likely to choose procedure based specialties and are more concerned with the reputation of the specialty as well as the anticipated salary. In contrast, residents choosing non-procedure based specialties are more concerned with issues related to lifestyle, including work-related stress, work hours and time for leisure as well as the patient populations

    Ultrasound is a critical diagnostic imaging tool in obstetrics and gynecology (Ob/Gyn). Obstetric ultrasound is taught during residency, but we suspected a gap in Gyn ultrasound education. Proficiency in Gyn ultrasound allows real-time interpretation and management of pelvic disease and facilitates technical skill development for trainees learning blinded procedures. This study sought to evaluate ultrasound education in Canada's Ob/Gyn residency programs and assess whether residents and physicians perceived a need for a formalized Gyn ultrasound curriculum. We distributed a needs assessment survey to residents enrolled in Canadian Ob/Gyn residency programs and to all obstetrician/gynecologists registered as members of the Society of Obstetricians and Gynaecologists of Canada. Residents were asked to specify their current training in ultrasound and to rate the adequacy of their curriculum. All respondents rated the importance of proficiency in pelvic ultrasound for practicing obstetrician/gynecologists as well as the perceived need for formalized ultrasound training in Ob/Gyn residency programs. Eighty-two residents and 233 physicians completed the survey. Extents and types of ultrasound training varied across residency programs. Most residents reported inadequate exposure to Gyn ultrasound, and most residents and physicians agreed that it is important for obstetrician/gynecologists to be proficient in Gyn ultrasound and that the development of a standardized Gyn ultrasound curriculum for residency programs is important. Current ultrasound education in Ob/Gyn varies across Canadian residency programs. Training in Gyn ultrasound is lacking, and both trainees and physicians confirmed the need for a standardized Gyn ultrasound curriculum for residency programs in Canada. © 2015 by the American Institute of Ultrasound in Medicine.

    Sickness presenteeism is defined as the act of attending one's job despite ill-health. Recently, physicians and other health care workers have become the focus of sickness presenteeism research, because presenteeism in this population can put patients at risk of infection. There are currently no data on this topic among physicians in Canada. The aim of this study was to investigate sickness presenteeism in paediatric resident physicians in Canada. We conducted an anonymous, online, cross-sectional survey study in which all paediatric residents in Canada were eligible. Outcomes of interest included prevalences of sickness presenteeism, sickness during the study period and voluntary self-appointed personal protective equipment use when engaging in sickness presenteeism. Response rate was 56.5% (N=323). During the previous 2 months, 61% (95% confidence interval [CI] 55.7 to 66.3) of respondents reported having experienced an illness and 59% (95% CI 53.7 to 64.5) of respondents had come to work sick. Of those who reported becoming ill during the study period, 97.0% (95% CI 94.6 to 99.4) reported coming to work while sick. There was no difference in prevalence when comparing across post-graduate year training levels. Extra personal protective equipment was used by 86% (95% CI 82.1 to 91.7) when engaging in sickness presenteeism. Sickness presenteeism is a common phenomenon among paediatric resident physicians. Our results should influence residents and supervising staff physicians to encourage appropriate self-care at home, rather than presenteeism.

    A method was developed using high-performance liquid chromatography to assay 4,4'-dinitrocarbanilide (DNC), the active ingredient in Nicarbazin, in eggshells collected from Canada geese fed a formulated feed fortified with Nicarbazin at doses of 0, 125, 250, and 500 microg/g. The method was developed using chicken eggshells fortified with DNC. The method was used to quantify DNC in both the shell-associated membranes and the calcified shell extracellular matrix. These values were compared to those obtained for a composite sample consisting of both the membranes and the calcified shell extracellular matrix. The validated method was used to quantify DNC in eggshells from geese fed fortified feed to ascertain the effect of Nicarbazin feed concentration on shell DNC concentration. DNC levels in the eggshells were highly correlated with feed dose.

    To survey the extent to which internal medicine housestaff experience abuse and discrimination in their training. Through a literature review and resident focus groups, we developed a self-administered questionnaire. In this cross-sectional survey, respondents were asked to record the frequency with which they experienced and witnessed different types of abuse and discrimination during residency training, using a 7-point Likert scale. Internal medicine housestaff in Canada. Of 543 residents in 13 programs participating (84% response rate), 35% were female. Psychological abuse, as reported by attending physicians (68%), patients (79%), and nurses or other health workers (77%), was widespread. Female residents experienced gender discrimination by attending physicians (70%), patients (88%), and nurses (71%); rates for males were 23%, 38%, and 35%, respectively. Females reported being sexually harassed more often than males, by attending physicians (35% vs 4%, p discrimination and homophobic remarks in the workplace, perpetrated by all groups of health professionals. Psychological abuse, gender discrimination, sexual harassment, physical abuse, homophobia, and racial discrimination are prevalent problems during residency training. Housestaff, medical educators, allied health workers, and the public need to work together to address these problems in the training environment.

    Full Text Available The fast real-time application message is an object-oriented substation event—GOOSE (Generic Object Oriented Substation Event. It mainly works on the process layers and bay layers of digital substation. GOOSE intelligent substation communication network can realize the key function of the overall intelligent sub-station functions. This paper will make a systematic analysis of GOOSE. At first, it will provide a detailed analysis of the transmission mechanism and process of GOOSE message. As certain practical operability lacks the actual application of the multicast filtering method which is applied to GOOSE message based on IEC61850 standard, this paper will summarize three message filtering methods, compare the advantages and disadvantages in topological networks of different kinds in accordance with the instantaneity of GOOSE intelligent substation communication network and draw a conclusion that the independent configuration scheme of GOOSE and SV can adapt to the requirement of times, so as to provide theoretical references for the selection of practical intelligent substation communication network in the future.

    Full Text Available Abstract Background Few Canadian studies have examined stress in residency and none have included a large sample of resident physicians. Previous studies have also not examined well-being resources nor found significant concerns with perceived stress levels in residency. The goal of "The Happy Docs Study" was to increase knowledge of current stressors affecting the health of residents and to gather information regarding the well-being resources available to them. Findings A questionnaire was distributed to all residents attending all medical schools in Canada outside of Quebec through the Canadian Association of Internes and Residents (CAIR during the 2004–2005 academic years. In total 1999 resident physicians responded to the survey (35%, N = 5784 residents. One third of residents reported their life as "quite a bit" to "extremely" stressful (33%, N = 656. Time pressure was the most significant factor associated with stress (49%, N = 978. Intimidation and harassment was experienced by more than half of all residents (52%, N = 1050 with training status (30%, N = 599 and gender (18%, N = 364 being the main perceived sources. Eighteen percent of residents (N = 356 reported their mental health as either "fair" or "poor". The top two resources that residents wished to have available were career counseling (39%, N = 777 and financial counseling (37%, N = 741. Conclusion Although many Canadian resident physicians have a positive outlook on their well-being, residents experience significant stressors during their training and a significant portion are at risk for emotional and mental health problems. This study can serve as a basis for future research, advocacy and resource application for overall improvements to well-being during residency.

    Pharyngeal swabs were collected from 298 lesser snow geese (Chen caerulescens caerulescens) at Banks Island (Northwest Territories. Canada) in the summer of 1994. Pasteurella multocida serotype 1 was isolated from an adult male bird and P. multocida serotype 3 was isolated from an adult female goose. Pathogenicity of the serotype 1 isolate was confirmed by inoculation in Pekin ducks (Anas platyrhynchos). The serotype 3 isolate was non-pathogenic in Pekin ducks. This is the first documented isolation of pathogenic P. multocida serotype 1 from apparently healthy wild snow geese.

    Pediatric neurology trainee numbers have grown considerably in Canada; recent research, however, has shown that the number of pediatric neurology graduates is outpacing the need for future pediatric neurologists. The purpose of this study was to seek the opinion of pediatric neurology program directors and trainees regarding possible solutions for this issue. Two focus groups were convened during the Canadian Neurological Sciences Federation annual congress in June 2012; one consisted of current and former program directors, and the other of current pediatric neurology trainees. Groups were asked for their perceptions regarding child neurology manpower issues in Canada as well as possible solutions. Focus groups were audio-recorded and transcribed for analysis. Theme-based qualitative analysis was used to analyze the transcripts. Major themes emerging from both focus groups included the emphasis on community pediatric neurology as a viable option for trainees, including the need for community mentors; recognizing the needs of underserviced areas; and establishing academic positions for community preceptors. The need for career mentoring and support structures during residency training was another major theme which arose. Program directors and trainees also gave examples of ways to reduce the current oversupply of trainees in Canada, including limiting the number of trainees entering programs, as well as creating a long-term vision of child neurology in Canada. A nationwide dialogue to discuss the supply and demand of manpower in academic and community pediatric neurology is essential. Career guidance options for pediatric neurology trainees across the country merit further strengthening.

    To compare chronic illnesses, economic dependence and health-care use by immigrants and native-born Canadians. A secondary analysis of the Canada Community Health Survey national data (2009-2010) was conducted. Recent and established immigrants were healthier than native-born Canadians. Healthy, established immigrants were more likely than native-born Canadians to be working, and no more likely to use transfer payments. Health-challenged recent immigrants had high employment rates, but low rates of health care. Health-challenged established immigrants and native born were equally likely to be working, depending on transfer payments and using health care. Regardless of nativity or health, education, male gender and linguistic fluency increased the probability of employment. Female gender and advancing age increased the likelihood of dependency. Residents of Canada's most prosperous regions were the most likely to be employed and the least likely to receive transfer payments. Immigrants with chronic illnesses do not inevitably dilute the economic benefits of immigration or create excessive burden. Timely programs to promote integration can help ensure a favourable balance between economic contribution and social cost. Neglecting the health of new immigrants may eventuate in long-term disability.

    The genomic structure and composition of an avian metapneumovirus (aMPV) recently isolated from wild Canada geese (goose 15a/01) in the United States, together with its replication, virulence, and immunogenicity in domestic turkeys, were investigated. The sizes of seven of the eight genes, sequence identity, and genome organization of goose aMPV were similar to those of turkey aMPV subtype C (aMPV/C) strains, indicating that it belonged to the subtype. However, the goose virus contained the largest attachment (G) gene of any pneumovirus or metapneumovirus, with the predicted G protein of 585 amino acids (aa) more than twice the sizes of G proteins from other subtype C viruses and human metapneumovirus and more than 170 aa larger than the G proteins from the other aMPV subtypes (subtypes A, B, and D). The large G gene resulted from a 1,015-nucleotide insertion at 18 nucleotides upstream of the termination signal of the turkey aMPV/C G gene. Three other aMPV isolates from Canada geese had similarly large G genes, whereas analysis of recent aMPV strains circulating in U.S. turkeys did not indicate the presence of the goose virus-like strain. In vitro, the goose virus replicated to levels (2 × 105 to 5 × 105 50% tissue culture infective dose) comparable to those produced by turkey aMPV/C strains. More importantly, the virus replicated efficiently in the upper respiratory tract of domestic turkeys but with no clinical signs in either day-old or 2-week-old turkeys. The virus was also horizontally transmitted to naïve birds, and turkey infections with goose 15a/01 induced production of aMPV-specific antibodies. Challenging day-old or 2-week-old turkeys vaccinated with live goose aMPV resulted in lower clinical scores in 33% of the birds, whereas the rest of the birds had no detectable clinical signs of the upper respiratory disease, suggesting that the mutant virus may be a safe and effective vaccine against aMPV infection outbreaks in commercial turkeys.

    Physical activity has numerous mental, emotional, spiritual and physical benefits. The factors influencing physical activity among First Nations children have not been well studied. The objective was to examine the associations between several intrapersonal, family and community factors and physical activity among First Nations school-aged children residing in First Nations communities. Participants consisted of 3,184 children (6-11 years old) from the 2008/10 First Nations Regional Health Survey, a representative sample of First Nations persons who reside in on-reserve and northern First Nations communities. The survey addresses a holistic range of health issues. Primary caregivers completed interviews to assess each child's moderate-to-vigorous physical activity (MVPA), participation in traditional physical activities, six intrapersonal factors, four family factors and two community factors. Based on primary caregiver reports, 72% of children accumulated a daily average of ≥60 minutes of MVPA and 54% participated in at least one traditional First Nations physical activity in the past year. Older age, having more people in the household, and having more relatives help the child understand their culture were independently associated with accumulating ≥60 minutes of MVPA. School attendance, use of First Nations language, having parents with a high school education, smaller community size, and having more community members help the child understand their culture were independently associated with participation in traditional First Nations physical activities. Among First Nations children, there are several correlates of physical activity from diverse ecological levels.

    2012-01-01

    Earthworms (Lumbricus castaneous and Dendrodrilus rubidus), their host soils and leaf litter were collected from a former gold mine with widespread arsenic (As) contamination in Nova Scotia, Canada and determined for total and speciated As. Resistance to As toxicity was investigated by measurement of DNA damage in exposed earthworm populations using the comet assay. Arsenobetaine (AB) was observed at low concentration in the earthworms but not in the host soil or leaf litter. Several different organoarsenic species were observed in the leaf litter and only inorganic As was found in the host soils. The results suggest that 1) adaptation to As toxicity in earthworms is widespread and not particular to a single species, 2) AB originates in the earthworm and not the consumed soil or leaf litter and 3) as previously hypothesised (), biotransformation of inorganic As to AB is not likely involved in the adaptation. - Highlights: ► Adaptation to toxicity and cycling of arsenic in earthworms investigated at Canadian gold mine. ► Earthworms resistant to highly contaminated, genotoxic soils. ► Arsenobetaine present in earthworms but not soil or leaf litter. ► Arsenic resistance in earthworms is widespread and not species specific. - Adaptation of earthworms to arsenic contaminated soils is widespread and not species specific.

    Communication errors are considered one of the major causes of sentinel events. Our aim was to assess the process of patient handoff among junior surgical residents and to determine ways in which to improve the handoff process. We conducted nationwide surveys that included all accredited general surgery residency programs in the United States and Canada. Of the 244 American and 17 Canadian accredited surgical residency programs contacted, 65 (27%) and 12 (71%), respectively, participated in the survey. Of the American and Canadian respondents, 66% and 69%, respectively, were from postgraduate year (PGY) 1, and 32% and 29%, respectively, were from PGY 2; 85 (77%) and 50 (96%), respectively, had not received any training about patient handoff before their surgical residency, and 27% and 64%, respectively, reported that the existing handoff system at their institutions did not adequately protect patient safety. Moreover, 29% of American respondents and 37% of Canadian respondents thought that the existing handoffs did not support continuity of patient care. Of the American residents, 67% and 6% reported receiving an incomplete handoff that resulted in minor and major patient harm, respectively. These results mirrored those from Canadian residents (63% minor and 7% major harm). The most frequent factor reported to improve the patient handoff process was standardization of the verbal handoff. Our survey results indicate that the current patient handoff system contributes to patient harm. More efforts are needed to establish standardized forms of verbal and written handoff to ensure patient safety and continuity of care.

    Building and operating the CMS Detector is a complicated endeavour! Now, more than 20 years after the detector was conceived, the CMS Bologna group proposes to follow the steps of this challenging project by playing "The Higgs Boson Goose Game", illustrating CMS activities and goals. The concept of the game is inspired by the traditional "Game of the Goose". The underlying idea is that the progress of building and operating a detector at the LHC is similar to the progress of the pawns on the game board: it is fast at times, bringing rewards and satisfaction, while sometimes unexpected problems cause delays or even a step back requiring CMS scientists to use all of their skill and creativity to devise new solutions.

    Falls continue to be a problem for older people in long-term care (LTC) and retirement home (RH) settings and are associated with significant morbidity and health care use. Fall-risk increasing drugs (FRIDs) are known to increase fall risk and represent modifiable risk factors. There are limited data regarding the use of FRIDs in contemporary LTC and RH settings, and it has not been well documented to what extent medication regimens are reviewed and modified for those who have sustained falls. The objective of this study is to characterize medication related fall risk factors in LTC and RH residents and on-going use of medications known to increase fall risk. Retrospective chart review of residents aged >65 who sustained one or more falls living in LTC or RH settings. 105 residents who fell one or more times during 2009-2010 were identified with a mean age of 89 years, a mean of nine scheduled medications and seven diagnoses, and 83% were women. Residents in LTC were ostensibly at higher risk for falls relative to those in RH settings as suggested by higher proportion of residents with multiple falls, multiple comorbidities, comorbidities that increase fall risk and visual impairment. Post fall injuries were sustained by 42% of residents, and residents in RH sustained more injuries relative to LTC residents (47 vs 34%). Use of FRIDs such as benzodiazepines, antipsychotic, antidepressant and various antihypertensive drugs was common in the present sample. No medication regimen changes were noted in the 6-month post fall period. The present study documented common use FRIDs by LTC and RH residents with multiple falls. These potentially modifiable falls risk factors are not being adequately addressed in contemporary practice, demonstrating that there is much room for improvement with regards to the safe and appropriate use of medications in LTC and RH residents.

    2017-08-01

    The paper seeks to identify aspects of care that may be easily modified to yield a desired level of improvement in residents' overall satisfaction with nursing homes, comparing data across Canada and Italy. Using a structured questionnaire, 681 and 1116 nursing home residents were surveyed in Ontario in 2009 and in Tuscany in 2012, respectively. Fourteen items were common to the surveys, including willingness to recommend (WTR), which was used as the dependent variable and measure of global satisfaction. The other analogous items were entered as covariates in ordinal logistic regression models predicting residents' WTR in each jurisdiction separately. Regression coefficients were then incorporated into a constrained nonlinear optimization problem selecting the most efficient combination of predictors necessary to increase WTR by as much as 15%. Staff-related aspects of care were selected first in the optimization models of each jurisdiction. In Ontario, to improve WTR the primary focus should be on staff relationships with residents, while in Tuscany it was the technical skill and knowledge of staff that was selected first by the optimization model. Different optimization solutions might mean that the strategies required to improve global satisfaction in one jurisdiction could be different than those for the other jurisdictions. The optimization model employed provides a novel solution for prioritizing areas of focus for quality improvement for nursing homes. Copyright © 2017 The Authors. Published by Elsevier B.V.

    2016-07-01

    The objectives of this study were to determine whether grid-connected industrial wind turbines (IWTs) are a risk factor for poor sleep quality, and if IWT noise is associated with sleep parameters in rural Ontarians. A daily sleep diary and actigraphy-derived measures of sleep were obtained from 12 participants from an IWT community and 10 participants from a comparison community with no wind power installations. The equivalent and maximum sound pressure levels within the bedroom were also assessed. No statistically significant differences were observed between IWT residents and non-IWT residents for any of the parameters measured in this study. Actigraphy and sleep diaries are feasible tools to understand the impact of IWTs on the quality of sleep for nearby residents. Further studies with larger sample sizes should be conducted to determine whether the lack of statistical significance observed here is a result of sample size, or reflects a true lack of association.

    Regulating risk, freedom of action, and autonomy in decision making are problems shared by both caregivers and residents in long term care settings, and may become the subject of tension and constant negotiation. This study focuses on long term care staff and management perceptions of day to day life in a care community which has gone through a culture change transition, where small residentially scaled households replace large instutional models of care. In each household, the setting is considered to be home for the 8-12 residents, creating a major shift of roles for the caregivers; they are, in essence, coming into a home rather than institutional environment as a place of work. This potentially changes the dynamics of both patterns of work for caregivers and patterns of daily living for residents. Participant observations and care staff interviews. Several key themes emrged which include: teamwork; the culture of care; regulating risk; the physical environment and care staff empowerment. An unexpected outcome was the consensus among care staff that it is they who feel at home while working in the care households, leading to empowerment in their work roles and a deeper understanding of the importance of their role in the lives of the residents.

    Ontario, the most populous province in Canada, has a universal healthcare system that routinely collects health administrative data on its 13 million legal residents that is used for health research. Record linkage has become a vital tool for this research by enriching this data with the Immigration, Refugees and Citizenship Canada Permanent Resident (IRCC-PR) database and the Office of the Registrar General's Vital Statistics-Death (ORG-VSD) registry. Our objectives were to estimate linkage rates and compare characteristics of individuals in the linked versus unlinked files. We used both deterministic and probabilistic linkage methods to link the IRCC-PR database (1985-2012) and ORG-VSD registry (1990-2012) to the Ontario's Registered Persons Database. Linkage rates were estimated and standardized differences were used to assess differences in socio-demographic and other characteristics between the linked and unlinked records. The overall linkage rates for the IRCC-PR database and ORG-VSD registry were 86.4 and 96.2 %, respectively. The majority (68.2 %) of the record linkages in IRCC-PR were achieved after three deterministic passes, 18.2 % were linked probabilistically, and 13.6 % were unlinked. Similarly the majority (79.8 %) of the record linkages in the ORG-VSD were linked using deterministic record linkage, 16.3 % were linked after probabilistic and manual review, and 3.9 % were unlinked. Unlinked and linked files were similar for most characteristics, such as age and marital status for IRCC-PR and sex and most causes of death for ORG-VSD. However, lower linkage rates were observed among people born in East Asia (78 %) in the IRCC-PR database and certain causes of death in the ORG-VSD registry, namely perinatal conditions (61.3 %) and congenital anomalies (81.3 %). The linkages of immigration and vital statistics data to existing population-based healthcare data in Ontario, Canada will enable many novel cross-sectional and longitudinal studies to

    Residents of rural (agricultural) areas are often suspected of being exposed to higher levels of pesticides than residents of urban areas. However, only a limited number of studies have specifically evaluated the impact of the geographical area of residence on pyrethroid and pyrethrin exposure in the general population. This study aimed at comparing the levels of biomarkers of exposure between an urban and rural, adult and children, population of the Province of Quebec, Canada. A total of 154 urban (Montreal) and 154 rural (Monteregie) participants provided a complete overnight timed-urine collection and filled a self-administered questionnaire. Urine samples were analyzed for pyrethroid and pyrethrin metabolites: cis- and trans-dichloro- and cis-dibromo- vinyldimethylcyclopropane carboxylic acids, phenoxy- and fluorophenoxy-benzoic acids and chrysanthemum dicarboxylic acid. Amounts of metabolites (pmol/12h par kilogram body weight) and their frequency of detection in the two populations were compared and interpreted with the help of the answers gathered by questionnaire. Adults and children from the rural area tended to excrete higher levels of the main urinary metabolites, the cis- and trans-dichlorovinyldimethylcyclopropane carboxylic acids and the phenoxybenzoic acid, than those living in the urban area. When the adults and children were combined, this difference was statistically significant for the phenoxybenzoic acid (p=0.020), marginally significant for the trans-dichlorovinyldimethylcyclopropane carboxylic acid (p=0.053) and nonsignificant for the cis-dichlorovinyldimethylcyclopropane carboxylic acid (p=0.158). The chrysanthemum dicarboxylic acid, the fluorophenoxybenzoic acid and the dibromovinyldimethylcyclopropane carboxylic acid were detected in much lower proportion but, in the case of the fluorophenoxybenzoic acid, the relative frequency of detection was statistically significantly higher (ppyrethroids and pyrethrins in the environment.

    Full Text Available ABSTRACT This paper examined the properties of goose eggshells to determine possible areas of improvement in egg transport and storage. First, we measured goose egg sizes and performed statistical tests, and found that the major axis, minor axis, and egg-shape index presented normal distribution. Eggshell thickness first increased and then decreased from the blunt end to the sharp end. Second, the shape of individual goose eggshell was measured using a 3D scanner. Volume equation, surface equation, and contour function of goose eggshell shape were obtained, exhibiting a highly symmetrical structure. Finally, goose eggs were compressed along their major and minor axes between two plates. Breaking strength was highly dependent on the shape index. A crack was found on the force point along the major axis of each goose egg.

    2014-03-21

    Recent surveys suggest few emergency medicine (EM) training programs have formal evidence-based medicine (EBM) or journal club curricula. Our primary objective was to describe the methods of EBM training in Royal College of Physicians and Surgeons of Canada (RCPSC) EM residencies. Secondary objectives were to explore attitudes regarding current educational practices including e-learning, investigate barriers to journal club and EBM education, and assess the desire for national collaboration. A 16-question survey containing binary, open-ended, and 5-pt Likert scale questions was distributed to the 14 RCPSC-EM program directors. Proportions of respondents (%), median, and IQR are reported. The response rate was 93% (13/14). Most programs (85%) had established EBM curricula. Curricula content was delivered most frequently via journal club, with 62% of programs having 10 or more sessions annually. Less than half of journal clubs (46%) were led consistently by EBM experts. Four programs did not use a critical appraisal tool in their sessions (31%). Additional teaching formats included didactic and small group sessions, self-directed e-learning, EBM workshops, and library tutorials. 54% of programs operated educational websites with EBM resources. Program directors attributed highest importance to two core goals in EBM training curricula: critical appraisal of medical literature, and application of literature to patient care (85% rating 5 - "most importance", respectively). Podcasts, blogs, and online journal clubs were valued for EBM teaching roles including creating exposure to literature (4, IQR 1.5) and linking literature to clinical practice experience (4, IQR 1.5) (1-no merit, 5-strong merit). Five of thirteen respondents rated lack of expert leadership and trained faculty educators as potential limitations to EBM education. The majority of respondents supported the creation of a national unified EBM educational resource (4, IQR 1) (1-no support, 5- strongly

    The aim of this work was to determine the microorganisms present and to investigate their metabolites that cause spoilage of many goose sausages produced in Friuli, a northeast region of Italy. The defect was observed by sensorial analysis using the "needle probing" technique; the spoiled sausages were unsafe and not marketable. Despite the addition of starter, the microorganisms, particularly enterococci and Enterobacteriaceae, grew during ripening and produced a large amount of biogenic amines; therefore, these sausages represented a risk to consumers. The production of those compounds was confirmed in vitro. Furthermore, a second cause of spoilage was attributed to moulds that grew during ripening; the fungi grew between the meat and casing, producing a large amount of total volatile nitrogen, and consequently an ammonia smell was present either in the ripening area or in the sausages. This is the first description of this type of defect in goose sausages. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available Newcastle disease (ND, caused by virulent strains of Newcastle disease virus (NDV, is a highly contagious disease of birds that is responsible for heavy economic losses for the poultry industry worldwide. However, little is known about host-virus interactions in waterfowl, goose. In this study, we aim to characterize the host immune response in goose, based on the previous reports on the host response to NDV in chickens. Here, we evaluated viral replication and mRNA expression of 27 immune-related genes in 10 tissues of geese challenged with a genotype VIId NDV strain of goose origin (go/CH/LHLJ/1/06. The virus showed early replication, especially in digestive and immune tissues. The expression profiles showed up-regulation of Toll-like receptor (TLR1–3, 5, 7 and 15, avian β-defensin (AvBD 5–7, 10, 12 and 16, cytokines interleukin (IL-8, IL-18, IL-1β and interferon-γ, inducible NO synthase (iNOS, and MHC class I in some tissues of geese in response to NDV. In contrast, NDV infection suppressed expression of AvBD1 in cecal tonsil of geese. Moreover, we observed a highly positive correlation between viral replication and host mRNA expressions of TLR1-5 and 7, AvBD4-6, 10 and 12, all the cytokines measured, MHC class I, FAS ligand, and iNOS, mainly at 72 h post-infection. Taken together, these results demonstrated that NDV infection induces strong innate immune responses and intense inflammatory responses at early stage in goose which may associate with the viral pathogenesis.

    Full Text Available MHC class I proteins mediate functions in anti-pathogen defense. MHC diversity has already been investigated by many studies in model avian species, but here we chose the bar-headed goose, a worldwide migrant bird, as a non-model avian species. Sequences from exons encoding the peptide-binding region (PBR of MHC class I molecules were isolated from liver genomic DNA, to investigate variation in these genes. These are the first MHC class I partial sequences of the bar-headed goose to be reported. A preliminary analysis suggests the presence of at least four MHC class I genes, which share great similarity with those of the goose and duck. A phylogenetic analysis of bar-headed goose, goose and duck MHC class I sequences using the NJ method supports the idea that they all cluster within the anseriforms clade.

    The Beringia region of the Arctic contains 2 colonies of lesser snow geese (Chen caerulescens caerulescens) breeding on Wrangel Island, Russia, and Banks Island, Canada, and wintering in North America. The Wrangel Island population is composed of 2 subpopulations from a sympatric breeding colony but separate wintering areas, whereas the Banks Island population shares a sympatric wintering area in California, USA, with one of the Wrangel Island subpopulations. The Wrangel Island colony represents the last major snow goose population in Russia and has fluctuated considerably since 1970, whereas the Banks Island population has more than doubled. The reasons for these changes are unclear, but hypotheses include independent population demographics (survival and recruitment) and immigration and emigration among breeding or wintering populations. These demographic and movement patterns have important ecological and management implications for understanding goose population structure, harvest of admixed populations, and gene flow among populations with separate breeding or wintering areas. From 1993 to 1996, we neckbanded molting birds at their breeding colonies and resighted birds on the wintering grounds. We used multistate mark-recapture models to evaluate apparent survival rates, resighting rates, winter fidelity, and potential exchange among these populations. We also compared the utility of face stain in Wrangel Island breeding geese as a predictor of their wintering area. Our results showed similar apparent survival rates between subpopulations of Wrangel Island snow geese and lower apparent survival, but higher emigration, for the Banks Island birds. Males had lower apparent survival than females, most likely due to differences in neckband loss. Transition between wintering areas was low (<3%), with equal movement between northern and southern wintering areas for Wrangel Island birds and little evidence of exchange between the Banks and northern Wrangel Island

    Annotated genomes can provide new perspectives on the biology of species. We present the first de novo whole genome sequencing for the pink-footed goose. In order to obtain a high-quality de novo assembly the strategy used was to combine one short insert paired-end library with two mate-pair libraries. The pink-footed goose genome was assembled de novo using three different assemblers and an assembly evaluation was subsequently performed in order to choose the best assembler. For our data, ALLPATHS-LG performed the best, since the assembly produced covers most of the genome, while introducing the fewest errors. A total of 26,134 genes were annotated, with bird species accounting for virtually all BLAST hits. We also estimated the substitution rate in the pink-footed goose, which can be of use in future demographic studies, by using a comparative approach with the genome of the chicken, the mallard and the swan goose. A substitution rate of 1.38×10 -7 per nucleotide per generation was obtained when comparing the genomes of the two closely-related goose species (the pink-footed and the swan goose). Altogether, we provide a valuable tool for future genomic studies aiming at particular genes and regions of the pink-footed goose genome as well as other bird species. Copyright © 2017 Elsevier Inc.

    Falls are the leading cause of injury-related hospital admissions in Canadian older adults, accounting for 85 % of injury hospitalizations among older adults aged over 65 years. While many of these injuries can lead to death, the survival rates of fall-related injuries are rarely examined. This surveillance study examined the fall injury hospitalization and survival rates among older adults in the context of place. Saskatchewan's health administrative data on injury hospitalizations among individuals aged 65 years and over (n = 39,867) was utilized for this study. Variables of interest included age group, sex, and the geographical area of residence at the time of hospitalization (rural, urban, north). Logistic regression analysis was applied to determine the association of variables of interest (age group, sex, and area of residence at the time of hospitalization as the covariate) with frequency of fall injury hospitalizations. Probable time to death due to fall-related injury hospitalization was determined by survival analysis. Three key findings that emerged from the present study are the following: (1) fall injury hospitalizations accounted for 77 % of all injury hospitalizations; (2) fall injury hospitalization rates varied by age group, sex, and area of residence, with advancing age, women, and certain geographical areas showing higher rates; and (3) survival rates also varied by sex and area of residence. Women had longer survival estimates after a fall injury hospitalization compared to men, and those living in the north have the shortest survival estimates. The findings from the study highlighted the high rate of fall-related injury hospitalization among older adults varying with their age group, sex, and area of residence. These factors need to be considered in injury surveillance and fall prevention research as well as programs and policies that support the reduction of falls.

    Full Text Available As interferon-stimulated genes (ISGs, interferon-inducible transmembrane proteins 1 and 3 (IFITM1 and IFITM3 can effectively inhibit the replication of multiple viruses. Here, goose IFITM1 and IFITM3 were cloned and identified for the first time. The two proteins share the same topological structure and several important sites critical for the antiviral functions in other species are conserved in the goose. Goose IFITM1 and IFITM3 are most closely related to their respective orthologs in ducks; these proteins exhibited high mRNA transcript levels in immune-related tissues, including the thymus, bursa of Fabricius, and Harderian gland, compared to other tissues. Moreover, goose IFITM1 was highly constitutively expressed in gastrointestinal tract tissues, while goose IFITM3 was expressed in respiratory organs. Furthermore, goose IFITM3 was activated in goose peripheral blood mononuclear cells (PBMCs infected with Tembusu virus (TMUV or treated with Toll-like receptors (TLRs agonists, while only the R848 and Poly (I:C agonists induced significant upregulation of goose IFITM1. Furthermore, goose IFITM1 and IFITM3 were upregulated in the sampled tissues, to some extent, after TMUV infection. Notably, significant upregulation of goose IFITM1 and IFITM3 was detected in the cecum and cecal tonsil, where TMUV was primarily distributed. These data provide new insights into the immune effectors in geese and promote our understanding of the role of IFITM1 and IFITM3 in the defense against TMUV.

    Many refrigerators using CFC as a refrigerant are seen as the cause of the depletion of ozone. Hence, thermoacoustic was chosen as an alternative refrigerator that safe for environment. There are many variable that influenced the optimization of thermoacoustic design. One of them is thermal conductivity of material of stack. The Stack material must have a low thermal conductivity. In this research we used organic stack made of stem of goose down. It has superior thermal insulating. It means that they have the lowest thermal conductivity. The system uses no refrigerant or compressor, and the only mechanical moving part is the loudspeaker connected to a signal generator that produces the acoustic. The working fluid is air and the material of resonator is stainless steel. A series test on the laboratory found that there is a decrease of 5°C in temperature for about 2 minutes.

    Full Text Available During a study on high mortality cases of goose embryo in Shandong Province, China (2014–2015, we isolated an H9N2 avian influenza virus (AIV strain (A/goose/Shandong/DP01/2014, DP01, which was supposedly the causative agent for goose embryo death. Sequence analysis revealed that DP01 shared 99.9% homology in the HA gene with a classic immune suppression strain SD06. To study the potential vertical transmission ability of the DP01 strain in breeder goose, a total of 105 Taizhou breeder geese, which were 360 days old, were equally divided into five groups (A, B, C, D, and E for experimental infection. H9N2 AIV (DP01 was used for inoculating through intravenous (group A, intranasal instillation (group B, and throat inoculation (group C routes, respectively. The geese in group D were inoculated with phosphate buffer solution (PBS and those in group E were the non-treated group. At 24 h post inoculation, H9N2 viral RNA could be detected at vitelline membrane, embryos, and allantoic fluid of goose embryos from H9N2 inoculated groups. Furthermore, the HA gene of H9N2 virus from vitelline membrane, embryo, allantoic fluid, and gosling shared almost 100% homology with an H9N2 virus isolated from the ovary of breeder goose, which laid these eggs, indicating that H9N2 AIV can be vertically transmitted in goose. The present research study provides evidence that vertical transmission of H9N2 AIV from breeding goose to goslings is possible.

    Human disturbance and loss of nesting habitat were more important factors than chlorinated hydrocarbons in changing heron reproductive success. - Over the period 1977-2000, eggs of Pacific great blue heron (Ardea herodias fannini) were collected from 23 colonies along the southern coast of British Columbia, Canada, and analyzed for persistent organochlorine (OC) pesticides and polychlorinated biphenyls (PCBs). Concentrations of OC pesticides in eggs declined sharply in the late 1970s, after which there were minimal changes. The sums of PCB congeners were not reduced appreciably during the 1980s and 1990s, but Aroclor 1260 concentrations suggested a sharp decline in PCB contamination of eggs in the late 1970s, similar to that shown for OC pesticides. Eggs collected along or near the Fraser River delta showed higher levels of most pesticides compared to other monitored colonies. Although the delta lands support a long-standing agricultural economy, the primary factors influencing OC levels in the delta colonies were thought to be driven by estuarine processes. We suggest two possible influencing factors were: 1) a greater rate of bioaccumulation in the estuary due to the deposition of particulates collected over a vast area encompassed by the Fraser River watershed; or 2) a higher rate of biomagnification in the estuary due to species differences at lower trophic levels of the heron food chain. Eggs from urban colonies contained higher levels of PCBs. The congener pattern was not clearly different from that observed in less contaminated eggs from rural and pulp mill-influenced colonies, except that colonies in Vancouver had greater proportions of PCB-66, suggesting a local source of Aroclor 1242. Productivity in the coastal heron colonies was highly variable over the period of study, with 71% of recorded colony-wide reproductive failures occurring in colonies near pulp mills. However, the predominant factors influencing reproductive success were probably disturbance

    Nicarbazin (NCZ), a coccidiostat commonly used in the poultry industry, causes reduced hatchability and egg quality in layer hens at a concentration of 125 ppm (8.4 mg/kg) in the feed. Although this effect is undesirable in the poultry industry, NCZ could provide a useful wildlife contraception tool for waterfowl, particularly urban geese. We tested the absorption of NCZ in chickens (Gallus gallus), mallards (Anas platyrhynchos), and Canada geese (Branta canadensis) gavaged with 8.4 mg of NCZ/kg per bird each day for 8 d. Plasma levels of 4,4'-dinitrocarbanilide (DNC) differed significantly among species. Peak plasma DNC levels were 2.87 +/- 0.15 microg/mL, 2.39 +/- 0.15 microg/mL, and 1.53 +/- 0.15 microg/ mL in chickens, mallards, and Canada geese respectively. It took 6 d to obtain peak DNC levels in chickens as opposed to 8 d in mallards and Canada geese. The half life of DNC in plasma was 1.43 d in chickens, 0.72 d in mallards, and 1.26 d in Canada geese. Mallards eliminated 100% of plasma DNC 4 d post-treatment, whereas Canada geese eliminated 100% of plasma DNC 8 d post-treatment. Chickens had only eliminated 99% of plasma DNC 8 d post-treatment. Mallard plasma DNC levels were highly correlated with Canada goose plasma DNC levels. This research showed mallards are an ideal model species for the Canada goose for future reproductive studies on NCZ in a laboratory setting. However, levels higher than 8.4 mg/kg must be fed to waterfowl in order to obtain a plasma level comparable to chickens.

    A prototype software package for a fully interactive Generalized Object-Oriented Simulation Environment (GOOSE) is being developed at Oak Ridge National Laboratory. Dynamic models are easily constructed and tested; fully interactive capabilities allow the user to alter model parameters and complexity without recompilation. This environment provides assess to powerful tools such as numerical integration packages, graphical displays, and online help. In GOOSE, portability has been achieved by creating the environment in Objective-C 1 , which is supported by a variety of platforms including UNIX and DOS. GOOSE Version 1.4 introduces new enhancements like the capability of creating ''initial,'' ''dynamic,'' and ''digital'' methods. The object-oriented approach to simulation used in GOOSE combines the concept of modularity with the additional features of allowing precompilation, optimization, testing, and validation of individual modules. Once a library of classes has been defined and compiled, models can be built and modified without recompilation. GOOSE Version 1.4 is primarily command-line driven

  1. Individual-area relationship best explains goose species density in wetlands.

    Directory of Open Access Journals (Sweden)

    Yong Zhang

    Full Text Available Explaining and predicting animal distributions is one of the fundamental objectives in ecology and conservation biology. Animal habitat selection can be regulated by top-down and bottom-up processes, and is mediated by species interactions. Species varying in body size respond differently to top-down and bottom-up determinants, and hence understanding these allometric responses to those determinants is important for conservation. In this study, using two differently sized goose species wintering in the Yangtze floodplain, we tested the predictions derived from three different hypotheses (individual-area relationship, food resource and disturbance hypothesis to explain the spatial and temporal variation in densities of two goose species. Using Generalized Linear Mixed Models with a Markov Chain Monte Carlo technique, we demonstrated that goose density was positive correlated with patch area size, suggesting that the individual area-relationship best predicts differences in goose densities. Moreover, the other predictions, related to food availability and disturbance, were not significant. Buffalo grazing probably facilitated greater white-fronted geese, as the number of buffalos was positively correlated to the density of this species. We concluded that patch area size is the most important factor determining the density of goose species in our study area. Patch area size is directly determined by water levels in the Yangtze floodplain, and hence modifying the hydrological regimes can enlarge the capacity of these wetlands for migratory birds.

    Goose Pasture Tarn, a 771-acre-foot reservoir in Summit County, Colorado, is the principal domestic water-storage facility for the Town of Breckenridge and collects runoff from approximately 42 square miles of the upper Blue River watershed. In the 40 years since the reservoir was constructed, deltaic deposits have accumulated at the mouths of two perennial streams that provide most of the inflow and sediment to the reservoir. The Blue River is a low-gradient braided channel and transports gravel- to silt-size sediment. Indiana Creek is a steep-gradient channel that transports boulder- to silt-size sediment. Both deltas are composed predominantly of gravel, sand, and silt, but silt has been deposited throughout the reservoir. In 2004, the U.S. Geological Survey, in cooperation with the Town of Breckenridge, began a study to determine the volume of accumulated sediment in Goose Pasture Tarn, the long-term sedimentation rate for the reservoir, and the particle-size and chemical characteristics of the sediment. Exposed delta deposits occupied 0.91 acre and had an estimated volume of 0.6 acre-foot in 2005. Aerial photographic analysis indicated both the Blue River and Indiana Creek deltas grew rapidly during time intervals that included larger-than-average annual flood peaks on the Blue River. Sediment-transport relations could not be developed for the Blue River or Indiana Creek because of minimal streamflow and infrequently observed sediment transport during the study; however, suspended-sediment loads ranged from 0.02 to 1.60 tons per day in the Blue River and from 0.06 to 1.55 tons per day in Indiana Creek. Bedload as a percentage of total load ranged from 9 to 27 percent. New reservoir stage-area and stage-capacity relations were developed from bathymetric and topographic surveys of the reservoir bed. The original 1965 reservoir bed topography and the accumulated sediment thickness were estimated from a seismic survey and manual probing. The surface area of Goose

    After a severe population reduction during the mid-20th century, the endangered Hawaiian Goose (Branta sandvicensis), or Nēnē, has only recently re-established its seasonal movement patterns on Hawai‘i Island. Little is currently understood about its movements and habitat use during the nonbreeding season. The objectives of this research were to identify habitats preferred by two subpopulations of the Nēnē and how preferences shift seasonally at both meso-and fine scales. From 2009 to 2011, ten Nēnē ganders were outfitted with 40-to 45-g satellite transmitters with GPS capability. We used binary logistic regression to compare habitat use versus availability and an information-theoretic approach for model selection. Meso-scale habitat modeling revealed that Nēnē preferred exotic grass and human-modified landscapes during the breeding and molting seasons and native subalpine shrubland during the nonbreeding season. Fine-scale habitat modeling further indicated preference for exotic grass, bunch grass, and absence of trees. Proximity to water was important during molt, suggesting that the presence of water may provide escape from introduced mammalian predators while Nēnē are flightless. Finescale species-composition data added relatively little to understanding of Nēnē habitat preferences modeled at the meso scale, suggesting that the meso-scale is appropriate for management planning. Habitat selection during our study was consistent with historical records, although dissimilar from more recent studies of other subpopulations. Nēnē make pronounced seasonal movements between existing reserves and use distinct habitat types; understanding annual patterns has implications for the protection and restoration of important seasonal habitats.

  4. A Vocal-Based Analytical Method for Goose Behaviour Recognition

    2012-03-01

    Full Text Available Since human-wildlife conflicts are increasing, the development of cost-effective methods for reducing damage or conflict levels is important in wildlife management. A wide range of devices to detect and deter animals causing conflict are used for this purpose, although their effectiveness is often highly variable, due to habituation to disruptive or disturbing stimuli. Automated recognition of behaviours could form a critical component of a system capable of altering the disruptive stimuli to avoid this. In this paper we present a novel method to automatically recognise goose behaviour based on vocalisations from flocks of free-living barnacle geese (Branta leucopsis. The geese were observed and recorded in a natural environment, using a shielded shotgun microphone. The classification used Support Vector Machines (SVMs, which had been trained with labeled data. Greenwood Function Cepstral Coefficients (GFCC were used as features for the pattern recognition algorithm, as they can be adjusted to the hearing capabilities of different species. Three behaviours are classified based in this approach, and the method achieves a good recognition of foraging behaviour (86–97% sensitivity, 89–98% precision and a reasonable recognition of flushing (79–86%, 66–80% and landing behaviour(73–91%, 79–92%. The Support Vector Machine has proven to be a robust classifier for this kind of classification, as generality and non-linearcapabilities are important. We conclude that vocalisations can be used to automatically detect behaviour of conflict wildlife species, and as such, may be used as an integrated part of awildlife management system.

    The purpose of this study was to further understand the health promotion behaviors of Korean goose mothers in the North America area. Health promotion behaviors measured in this study were self-actualization, health responsibility, physical activity, nutrition, interpersonal relations, and stress management. The study is part of a larger study which used surveys (N=140) and in-person interviews (n=18). In this study, analysis of survey results is presented. Advertisements and snowballing technique were used to recruit study participants. Pearson's correlation was used to explore the relationships between health promotion and social support, acculturation attitudes, and perceived family health. Multiple regressions were used to examine the predictors of health promotion behaviors. Women in the study were most frequently engaging in self-actualization and least in physical activity. Physical activity did not correlate with any of the study variables. When multiple regressions were performed, the model for each health promotion behavior was found to be statistically significant except for that of physical activity. Overall, study variables worked differently across models. Social support predicted self-actualization, health responsibility, interpersonal relations, and stress management. None of the acculturation attitudes predicted health promotion behaviors. The subdimensions of perceived family health predicted health promotion behaviors except physical activity. The findings of this study contributed to the body of knowledge of health promotion among international migrant populations by identifying the differential effects of social support, acculturation attitudes, and perceived family health for six areas of health promotion.

  7. Towards a solution to the goose-agriculture conflict in North Norway, 1988-2012: the interplay between policy, stakeholder influence and goose population dynamics.

    Directory of Open Access Journals (Sweden)

    Ingunn M Tombre

    Full Text Available This paper presents results from a multidisciplinary study of a negotiation process between farmers and wildlife authorities which led to an agricultural subsidy scheme to alleviate conflicts between agriculture and geese in Norway. The Svalbard-breeding population of pink-footed geese Anser brachyrhynchus has increased considerably over the last decades and conflicts with farmers have escalated, especially at stopover sites in spring when geese feed on newly sprouted pasture grass. In Vesterålen, an important stopover site for geese in North Norway, farmers deployed scaring of geese at varying intensity dependent on the level of conflict during 1988-2012. We assessed the efficiency of a subsidy scheme established in 2006, in terms of its conflict mitigation, reflected in a near discontinuation of scaring activities. The presence of pink-footed geese was analysed in relation to scaring intensity, the total goose population size and the increasing occurrence of another goose species, the barnacle goose Branta leucopsis. Scaring significantly affected the number of geese staging in Vesterålen, both in absolute and relative terms (controlling for total population size. The geese responded immediately to an increased, and reduced, level of scaring. Despite the establishment of the subsidy scheme, the number of pink-footed geese has recently declined which is probably caused by the increasing number of barnacle geese. For the farmers, the subsidy scheme provides funding that reduces the economic costs caused by the geese. Sustaining a low level of conflict will require close monitoring, dialogue and adaptation of the subsidy scheme to cater for changes in goose population dynamics.

  10. Identification of protective components that prevent the exacerbation of goose fatty liver: Characterization, expression and regulation of adiponectin receptors.

    Fat accumulation in the liver is a natural process in goose, which prepares goose for long-distance migration. In contrast to mammalian fatty liver that usually progresses into an irreversible status, steatohepatitis, goose fatty liver can return to normal without obvious pathological damage, suggesting a protective system exists in goose liver. This study was to identify the components of this system. We first focused on goose adiponectin receptor 1 and 2 (Adipor1/2) as they have ceramidase activity, and can cleave ceramide, a group of proinflammatory signaling lipid species. Quantitative analysis indicated that tumor necrosis factor alpha (Tnfα), a key proinflammatory cytokine, was down-regulated in goose fatty liver by overfeeding. This inhibition of Tnfα was accompanied with reduced adiponectin and increased Adipor1/2 in the adipose tissues and in the livers of the overfed geese, respectively. To investigate the regulation of goose Adipor2 in the context of fatty liver, we treated goose primary hepatocytes with fatty liver associated factors. Data indicated that Adipor2 was upregulated by glucose and oleate but not palmitate. Its expression was even suppressed by high level of insulin. The regulation of Adipor1 by these factors was quite similar to that of Adipor2 except that glucose did not induce Adipor1. Together, these findings suggest the upregulation of Adipor1/2 may, at least partially, contribute to the inhibition of inflammation in goose fatty liver, and the expression of Adipor1/2 can be regulated by fatty liver-associated factors.

    We expanded the Nebraska Light Goose Conservation Order (LGCO) harvest survey (NE, USA) in spring 2012 to assess migratory bird hunter opinions regarding future management strategies for controlling light goose populations. Although hunters strongly agreed that population control of light geese was an important wildlife management issue, they were generally unsupportive of wildlife officials using forms of direct control methods to control light goose populations. Respondents who indicated participation in the 2012 LGCO were also less supportive of any form of direct control compared with migratory bird hunters who did not participate in the LGCO. When presented with alternative methods by wildlife officials for future light goose population control, respondents were most supportive of wildlife agencies selectively shooting light geese on migration and wintering areas and least supportive of wildlife officials using bait with approved chemicals to euthanize light geese. A clear understanding of public perception of various potential direct-control options will likely assist wildlife biologists in making informed decisions on how to proceed with population control of light geese.

  19. Inundation, sedimentation, and subsidence creates goose habitat along the Arctic coast of Alaska

    The Arctic Coastal Plain of Alaska is characterized by thermokarst lakes and drained lake basins, and the rate of coastal erosion has increased during the last half-century. Portions of the coast are sea level for kilometers inland, and are underlain by ice-rich permafrost. Increased storm surges or terrestrial subsidence would therefore expand the area subject to marine inundation. Since 1976, the distribution of molting Black Brant (Branta bernicla nigricans) on the Arctic Coastal Plain has shifted from inland freshwater lakes to coastal marshes, such as those occupying the Smith River and Garry Creek estuaries. We hypothesized that the movement of geese from inland lakes was caused by an expansion of high quality goose forage in coastal areas. We examined the recent history of vegetation and geomorphological changes in coastal goose habitat by combining analysis of time series imagery between 1948 and 2010 with soil stratigraphy dated using bomb-curve radiocarbon. Time series of vertical imagery and in situ verification showed permafrost thaw and subsidence of polygonal tundra. Soil stratigraphy and dating within coastal estuaries showed that non-saline vegetation communities were buried by multiple sedimentation episodes between 1948 and 1995, accompanying a shift toward salt-tolerant vegetation. This sedimentation allowed high quality goose forage plants to expand, thus facilitating the shift in goose distribution. Declining sea ice and the increasing rate of terrestrial inundation, sedimentation, and subsidence in coastal estuaries of Alaska may portend a 'tipping point' whereby inland areas would be transformed into salt marshes.

    Agouti signalling protein (ASIP) is an endogenous antagonist of melanocortin-1 receptor (MC1R) and is involved in the regulation of pigmentation in mammals. The objective of this study was to identify and characterise the ASIP gene in domestic goose. The goose ASIP cDNA consisted of a 44-nucleotide 5'-terminal untranslated region (UTR), a 390-nucleotide open-reading frame (ORF) and a 45-nucleotide 3'-UTR. The length of goose ASIP genomic DNA was 6176 bp, including three coding exons and two introns. Bioinformatic analysis indicated that the ORF encodes a protein of 130 amino-acid residues with a molecular weight of 14.88 kDa and an isoelectric point of 9.73. Multiple sequence alignments and phylogenetic analysis showed that the amino-acid sequence of ASIP was conserved in vertebrates, especially in the avian species. RT-qPCR showed that the goose ASIP mRNA was differentially expressed in the pigment deposition tissues, including eye, foot, feather follicle, skin of the back, as well as in skin of the abdomen. The expression level of the ASIP gene in skin of the abdomen was higher than that in skin of the back. Those findings will contribute to further understanding the functions of the ASIP gene in geese plumage colouring.

    In response to overfeeding, the Landes goose develops a fatty liver that is twice as large as that of the Poland goose, despite similar food intake. The role of hepatic lipogenesis in the genetic susceptibility to fatty liver was assessed in male overfed geese of the two breeds. For a similar hepatic protein content, total activities of malic enzyme, glucose-6-phosphate dehydrogenase, acetyl-Coa-carboxylase and fatty acid synthase, and specific activity and mRNA level of malic enzyme were about two-fold higher in the Landes goose. In the Poland goose, the weight of the fatty liver was correlated positively with the specific activity of ME and the VLDL concentration, which was not the case in the Landes breed. These results show that: (1) hepatic lipogenesis remains very active until the end of the overfeeding period; (2) the pentose-phosphate pathway may function in birds, contrary to what is assumed usually; (3) the level of hepatic lipogenesis is a major factor in the susceptibility to hepatic steatosis in different breeds of geese; and (4) ME activity may be a limiting factor of lipid synthesis in the less susceptible Poland breed.

  6. The development of a genome wide SNP set for the Barnacle goose Branta leucopsis.

    Rudy M Jonker

    Full Text Available Migratory birds are of particular interest for population genetics because of the high connectivity between habitats and populations. A high degree of connectivity requires using many genetic markers to achieve the required statistical power, and a genome wide SNP set can fit this purpose. Here we present the development of a genome wide SNP set for the Barnacle Goose Branta leucopsis, a model species for the study of bird migration. We used the genome of a different waterfowl species, Mallard Anas platyrhynchos, as a reference to align Barnacle Goose second generation sequence reads from an RRL library and detected 2188 SNPs genome wide. Furthermore, we used chimeric flanking sequences, merged from both Mallard and Barnacle Goose DNA sequence information, to create primers for validation by genotyping. Validation with a 384 SNP genotyping set resulted in 374 (97% successfully typed SNPs in the assay, of which 358 (96% were polymorphic. Additionally, we validated our SNPs on relatively old (30 years museum samples, which resulted in a success rate of at least 80%. This shows that museum samples could be used in standard SNP genotyping assays. Our study also shows that the genome of a related species can be used as reference to detect genome wide SNPs in birds, because genomes of birds are highly conserved. This is illustrated by the use of chimeric flanking sequences, which showed that the incorporation of flanking nucleotides from Mallard into Barnacle Goose sequences lead to equal genotyping performance when compared to flanking sequences solely composed of Barnacle Goose sequence.

    Because much of the information concerning disturbance of waterfowl by aircraft is anecdotal, we examined behavioral responses of Pacific brant (Branta bernicla nigricans) and Canada geese (B. canadensis taverneri) to experimental overflights during fall staging at Izembek Lagoon, Alaska. These data were used to develop predictive models of brant and Canada goose response to aircraft altitude, type, noise, and lateral distance from flocks. Overall, 75% of brant flocks and 9% of Canada goose flocks flew in response to overflights. Mean flight and alert responses of both species were greater for rotary-wing than for fixed-wing aircraft and for high-noise than for low-noise aircraft. Increased lateral distance between an aircraft and a flock was the most consistent predictive parameter associated with lower probability of a response by geese. Altitude was a less reliable predictor because of interaction effects with aircraft type and noise. Although mean response of brant and Canada geese generally was inversely proportional to aircraft altitude, greatest response occurred at intermediate (305-760 m) altitudes. At Izembek Lagoon and other areas where there are large concentrations of waterfowl, managers should consider lateral distance from the birds as the primary criterion for establishing local flight restrictions, especially for helicopters.

    An assay protocol based on a monoclonal antibody-based competitive enzyme-linked immunosorbent assay (MAb-based C-ELISA) for detecting antibodies against goose parvovirus (GPV) and its virus-like particles (VLPs) is described. The assay was developed using baculovirus-expressed recombinant VP2 virus-like particles (rVP2-VLPs) as antigens and a monoclonal antibody against GPV as the competitive antibody. Of the four anti-GPV MAbs that were screened, MAb 1G3 was selected as it was blocked by the GPV positive serum. Based on the distribution of percent inhibition (PI) of the known negative sera (n=225), a cut-off value was set at 36% inhibition. Using this cut-off value, the sensitivity of the assay was 93.3% and the specificity was 95.8%, as compared with the gold standard (virus neutralization assay). The rVP2-VLPs did not react with anti-sera to other goose pathogens, indicating that it is specific for the recognization of goose parvovirus antibodies. The assay was then validated with serum samples from goslings vaccinated with several VLPs (rVP1-VLPs, rVP2-VLPs, rVP3-VLPs, and rCGV-VLPs) and other vaccines (inactivated and attenuated). The C-ELISA described in this study is a sensitive and specific diagnostic test and should have wide applications for the sero-diagnosis and immunologic surveillance of GPV.

    2005-01-01

    Purpose: Radiation oncology's popularity as a career in Canada has surged in the past 5 years. Consequently, resident numbers in Canadian radiation oncology residencies are at all-time highs. This study aimed to survey Canadian radiation oncology residents about their opinions of their specialty and training experiences. Methods and Materials: Residents of Canadian radiation oncology residencies that enroll trainees through the Canadian Resident Matching Service were identified from a national database. Residents were mailed an anonymous survey. Results: Eight of 101 (7.9%) potential respondents were foreign funded. Fifty-two of 101 (51.5%) residents responded. A strong record of graduating its residents was the most important factor residents considered when choosing programs. Satisfaction with their program was expressed by 92.3% of respondents, and 94.3% expressed satisfaction with their specialty. Respondents planning to practice in Canada totaled 80.8%, and 76.9% plan to have academic careers. Respondents identified job availability and receiving adequate teaching from preceptors during residency as their most important concerns. Conclusions: Though most respondents are satisfied with their programs and specialty, job availability and adequate teaching are concerns. In the future, limited time and resources and the continued popularity of radiation oncology as a career will magnify the challenge of training competent radiation oncologists in Canada

    2017-03-01

    In 2012, the four countries hosting the Svalbard population of pink-footed goose Anser brachyrhynchus along its flyway launched an International Species Management Plan for the population. One of the aims was to reduce conflicts between geese and agriculture to an acceptable level. Since 2006, Norway has offered subsidies to farmers that provide refuge areas for geese on their land. We evaluate the mid-Norwegian goose management subsidy scheme, with a view to its adjustment to prevailing ecological and socio-economic parameters. The analysis indicates that the legitimacy of the scheme is highly dependent on transparency of knowledge management and accountability of management scheme to the farming community. Among farmers, as well as front-line officials, outcomes of prioritisation processes within the scheme are judged unfair when there is an evident mismatch between payments and genuine damage. We suggest how the scheme can be made more fair and responsive to ecological changes, within a framework of adaptive management.

  14. Transcriptome profiling of the goose (Anser cygnoides ovaries identify laying and broodiness phenotypes.

    Directory of Open Access Journals (Sweden)

    Qi Xu

    Full Text Available BACKGROUND: The geese have strong broodiness and poor egg performance. These characteristics are the key issues that hinder the goose industry development. Yet little is known about the mechanisms responsible for follicle development due to lack of genomic resources. Hence, studies based on high-throughput sequencing technologies are needed to produce a comprehensive and integrated genomic resource and to better understand the biological mechanisms of goose follicle development. METHODOLOGY/PRINCIPAL FINDINGS: In this study, we performed de novo transcriptome assembly and gene expression analysis using short-read sequencing technology (Illumina. We obtained 67,315,996 short reads of 100 bp, which were assembled into 130,514 unique sequences by Trinity strategy (mean size = 753 bp. Based on BLAST results with known proteins, these analyses identified 52,642 sequences with a cut-off E-value above 10(-5. Assembled sequences were annotated with gene descriptions, gene ontology and clusters of orthologous group terms. In addition, we investigated the transcription changes during the goose laying/broodiness period using a tag-based digital gene expression (DGE system. We obtained a sequencing depth of over 4.2 million tags per sample and identified a large number of genes associated with follicle development and reproductive biology including cholesterol side-chain cleavage enzyme gene and dopamine beta-hydroxylas gene. We confirm the altered expression levels of the two genes using quantitative real-time PCR (qRT-PCR. CONCLUSIONS/SIGNIFICANCE: The obtained goose transcriptome and DGE profiling data provide comprehensive gene expression information at the transcriptional level that could promote better understanding of the molecular mechanisms underlying follicle development and productivity.

    The aim of this study was the expression of goose parvovirus capsid protein (VP3) and its epitopes in Escherichia coli cells. Expression of the whole VP3 protein provided an insufficient amount of protein. In contrast, the expression of two VP3 epitopes (VP3ep4, VP3ep6) in E. coli, resulted in very high expression levels. This may suggest that smaller parts of the GPV antigenic determinants are more efficiently expressed than the complete VP3 gene.

    The Arctic Coastal Plain of Alaska is characterized by thermokarst lakes and drained lake basins, and the rate of coastal erosion has increased during the last half-century. Portions of the coast are <1 m above sea level for kilometers inland, and are underlain by ice-rich permafrost. Increased storm surges or terrestrial subsidence would therefore expand the area subject to marine inundation. Since 1976, the distribution of molting Black Brant (Branta bernicla nigricans) on the Arctic Coastal Plain has shifted from inland freshwater lakes to coastal marshes, such as those occupying the Smith River and Garry Creek estuaries. We hypothesized that the movement of geese from inland lakes was caused by an expansion of high quality goose forage in coastal areas. We examined the recent history of vegetation and geomorphological changes in coastal goose habitat by combining analysis of time series imagery between 1948 and 2010 with soil stratigraphy dated using bomb-curve radiocarbon. Time series of vertical imagery and in situ verification showed permafrost thaw and subsidence of polygonal tundra. Soil stratigraphy and dating within coastal estuaries showed that non-saline vegetation communities were buried by multiple sedimentation episodes between 1948 and 1995, accompanying a shift toward salt-tolerant vegetation. This sedimentation allowed high quality goose forage plants to expand, thus facilitating the shift in goose distribution. Declining sea ice and the increasing rate of terrestrial inundation, sedimentation, and subsidence in coastal estuaries of Alaska may portend a ‘tipping point’ whereby inland areas would be transformed into salt marshes.

    Full Text Available Greylag goose populations are steadily increasing in north-western Europe. Although individuals breeding in the Netherlands have been considered mainly sedentary birds, those from Scandinavia or northern Germany fly towards their winter quarters, namely over France as far as Spain. This study aimed to determine the genetic structure of these birds, and to evaluate how goose populations mix. We used mitochondrial DNA and microsatellites from individuals distributed throughout the European Atlantic flyway, from breeding sites in Norway and the Netherlands to stopover and wintering sites in northern and south-western France. The mtDNA marker (CR1 D-Loop, 288 bp sequence, 144 ind. showed 23 different haplotypes. The genetic distances amongst individuals sampled in Norway, northern France and the Netherlands were low (range 0.012–0.013. Individuals in south-western France showed a slightly higher genetic distance compared to all other sampling areas (ranges 0.018–0.022. The NJ tree does not show evidence of any single clades grouping together all individuals from the same geographic area. Besides, individuals from each site are found in different branches. Bayesian clustering procedures on 14 microsatellites (169 individuals did not detect any geographically distinct cluster, and a high genetic admixture was recorded in all studied areas except for the individuals from the breeding sites in Norway, which were genetically very close. Estimation of migration rates through Bayesian inference confirms the scenario for the current mixing of goose populations.

    Full Text Available Interferons, as the first line of defense against the viral infection, play an important role in innate immune responses. Type III interferon (IFN-λ was a newly identified member of IFN family, which plays IFN-like antiviral activity. Towards a better understanding of the type III interferon system in birds, type III interferon lambda receptor (IFNLR1 was first identified in the Chinese goose. In this paper, we had cloned 1952 bp for goose IFNLR1 (goIFNLR1, including an ORF of 1539 bp, encoding a 512-amino acid protein with a 20 aa predict signal peptide at its N terminal and a 23 aa transmembrane region. The predicted amino acid sequence of goIFNLR1 has 90%, 73%, and 34% identity with duck IFNLR1 (predicted sequence, chicken IFNLR1, and human IFNLR1, respectively. And the age-related tissue distribution of goIFNLR1 was identified by Real Time quantitative PCR (RT-qPCR, we found that the goIFNLR1 has a mainly expression in epithelium-rich tissues similar to other species’, such as small intestinal, lung, liver, and stomach. Moreover, a relatively high expression of goIFNLR1 was also observed in the secondary immune tissues (harderian gland and cecal tonsil. The identification and tissue distribution of goIFNLR1 will facilitate further study of the role of IFN-λ in goose antiviral defense.

    Full Text Available Purpose: Proximal migration of the ureteric double J stent is a rare but known complication. We describe three cases where a minimally invasive technique for retrieval of displaced double J stents using Amplatz™ goose-neck snare was successful. Materials and Methods: A retrospective review of patients with displaced double J stent was carried out, in whom cystoscopy guided retrieval of double J stent was attempted with the help of Amplatz goose-neck snare under radiological control. Results: All three patients were under the age of 3 years. Two patients had migrated double J stent following pyeloplasty and in one patient the double J stent was displaced during a retrograde insertion of double J stent. In all cases, retrieval of displaced double J stent was successfully achieved using Amplatz goose-neck snare. There were no postoperative complications. Conclusion: Our method of retrieval of stent from renal pelvis is simple, safe and minimally invasive. This technique is a useful and safe alternative option for retrieval of proximally migrated double J stents in children.

    Clearly, faculty must work hard with residents to explore the nature of their resistance to a program's learning and growth opportunities. Initial steps to a deeper, more effective, and longer-lasting change process must be pursued. If resident resistance is mishandled or misunderstood, then learning and professional growth may be sidetracked and the purposes of residency training defeated. Listening to the whole person of the resident and avoiding the trap of getting caught up in merely responding to select resident behaviors that irritate us is critical. Every faculty member in the family practice residency program must recognize resistance as a form of defense that cannot immediately be torn down or taken away. Resident defenses have important purposes to play in stress reduction even if they are not always healthy. Residents, especially interns, use resistance to avoid a deeper and more truthful look at themselves as physicians. A family practice residency program that sees whole persons in their residents and that respects resident defenses will effectively manage the stress and disharmony inherent to the resistant resident.

    The SYG61v is an attenuated goose parvovirus (GPV) that has been used as a vaccine strain in China. The genome of SYG61v was sequenced to attempt to identify the genetic basis for the attenuation of this strain. The entire genome consists of 5102 nucleotides (nts), with four nt deletions compared to that of virulent strain B. The inverted terminal repeats (ITR) are 442 nts in length, of which 360 nts form a stem region, and 43 nts constitute the bubble region. Although mutations were observed throughout the ITR, no mismatch was found in the stem. Alignment with other pathogenic GPV strains (B, 82-0321, 06-0329, and YZ99-5) indicated that there are 10 and 11 amino acid mutations in the Rep1 and VP1 proteins of SYG61v, respectively. The complete genome of SYG61v was cloned into the pBluescript II vector and an infectious plasmid pSYG61v was generated. Infectious progeny virus was successfully rescued through transfection of the plasmid pSYG61v in embryonated goose eggs and yielded viral titers similar to its parental virus, as evaluated by ELD50.

    This thesis analyzes the concept of corporate residence, with particular reference to the law in the UK and Canada. It explores why corporate residence is relevant in tax policy, how corporate residence is understood in law, and how revenue authorities respond to the use and alleged 'abuse' of residence rules. Part I argues that the residence of taxpayers generally (individual or corporate) remains a relevant factor in international tax design, that taxation of corporations on the basis of re...

    Full Text Available This article is the product of exploratory field research conducted in Toronto, Canada. It consists of in-depth interviews of Latin American women from diverse countries who obtained temporary work visas as exotic dancers. The objective of the study is to determine the ways in which women are recruited in their countries of origin, transported to Canada and what happens to them upon arrival. The author proposes that the conditions inherent to migration, more than women's legal status, determines their emotional, economic and legal well-being. However, upon obtaining legal residency in Canada, abuse committed by employers and state agents is significantly reduced.

  8. Protection of the goose barnacle Pollicipes pollicipes, Gmelin, 1790 population: the Gaztelugatxe Marine Reserve (Basque Country, northern Spain

    Full Text Available Marine protected areas are expected to play a prominent role in the conservation of marine resources and fisheries management. In the Basque Country (northern Spain the small Marine Reserve of Gaztelugatxe (158 ha was established in 1998. One of the aspects taken into account in protecting this area was the overexploitation of the goose barnacle Pollicipes pollicipes. Now, after five years of protection, differences in density, biomass, size and weight of the goose barnacle are investigated inside the protected area (Aketze and Gaztelugatxe locations and outside of it, at the nearest locations (Izaro and Ogoño which have been continuously exploited. This contribution demonstrates that the reserve could be an efficient tool in preserving the goose barnacle populations in the area. Hence, density, biomass and allometric coefficients are higher in the protected areas. These locations are also associated with higher percentages of juveniles, together with a high number of large-sized individuals.

    Nicarbazin is being investigated as an infertility agent for the control of non-migratory Canada geese (Branta canadensis L) populations. Nicarbazin is presently registered for use as a coccidiostat for poultry. Geese fed sufficient quantities of nicarbazin will lay non-viable eggs. We established nicarbazin consumption by measuring the concentration of a component of the formulation, 4,4'-dinitrocarbanilide (DNC) in the egg contents (yolk, albumin) in non-viable eggs. To estimate the nicarbazin consumption of birds that laid viable eggs (eggs that hatched or contained an embryo), a high-performance liquid chromatography method was developed to measure the concentration of DNC in egg shells. A statistically significant correlation was established using linear regression between the mean concentrations of DNC in the egg shell and in the egg contents in non-viable eggs. Viable eggs were estimated to contain lower levels of DNC than non-viable eggs. DNC concentrations in both the egg contents and the egg shell increased with increases in nicarbazin dose in feed. Our method allows for the estimation of nicarbazin consumption and DNC dose in eggs under field conditions, which is important in developing an effective infertility agent for over-abundant non-migratory goose populations.

    Highlights: → All three capsid proteins can be expressed in insect cells in baculovirus expression system. → All three recombinant proteins were spontaneously self-assemble into virus-like particles whose size and appearance were similar to those of native purified GPV virions. → The immunogenicity of GPV-VLPs was better than commercial inactivated vaccine and attenuated vaccine. -- Abstract: Goose parvovirus (GPV), a small non-enveloped ssDNA virus, can cause Derzsy's disease, and three capsid proteins of VP1, VP2, and VP3 are encoded by an overlapping nucleotide sequence. However, little is known on whether recombinant viral proteins (VPs) could spontaneously assemble into virus-like particles (VLPs) in insect cells and whether these VLPs could retain their immunoreactivity and immunogenicity in susceptible geese. To address these issues, genes for these GPV VPs were amplified by PCR, and the recombinant VPs proteins were expressed in insect cells using a baculovirus expression system for the characterization of their structures, immunoreactivity, and immunogenicity. The rVP1, rVP2, and rVP3 expressed in Sf9 cells were detected by anti-GPV sera, anti-VP3 sera, and anti-His antibodies, respectively. Electron microscopy revealed that these rVPs spontaneously assembled into VLPs in insect cells, similar to that of the purified wild-type GPV virions. In addition, vaccination with individual types of VLPs, particularly with the rVP2-VLPs, induced higher titers of antibodies and neutralized different strains of GPVs in primary goose and duck embryo fibroblast cells in vitro. These data indicated that these VLPs retained immunoreactivity and had strong immunogenicity in susceptible geese. Therefore, our findings may provide a framework for development of new vaccines for the prevention of Derzsy's disease and vehicles for the delivery of drugs.

    The objective of the work was to investigate the color and lipid oxidation changes of goose breast meat packaged in vacuum and modified atmosphere (MA) conditions consisting of 80% O2, 20% CO2, and stored in refrigerated conditions at 4°C. Color stability was monitored by determining total heme pigments concentration; relative concentration of myoglobin, oxymyoglobin, and metmyoglobin; parameters of color L*, a*, b*, and sensory evaluation of the surface color. Lipid stability was measured by determining thiobarbituric acid reactive substances (TBARS). The samples were examined in 24 h after slaughter (unpacked muscles) and on d 4, 7, 9, 11 of storage (muscles packed in vacuum and in MA). Through the time of storage, samples packed in MA had higher TBARS values in comparison to the meat packed in vacuum. For samples packed in two types of atmospheres, the total pigments concentration decreased gradually within 11 d of storage. It was observed that relative metmyoglobin concentration increased whereas relative oxymyoglobin concentration decreased in total heme pigments in the MA stored muscle. The relative concentration of all three myoglobin forms sample packed in vacuum remained unchanged. The color parameters (L*, a*, b*) did not change for 11 d of storage for the vacuum packed meat. The value of the color parameter a* decreased and the value of the color parameters L* and b* increased in the samples packaged in MA. The data prove that if you store goose meat in MA (consisting of 80% O2, 20% CO2) or vacuum, the unchanged surface color is preserved for 9 and 11 day, respectively.Vacuum appears to be a better method as regards the maintaining of lipid stability in goose meat. © 2016 Poultry Science Association Inc.

    The New Jersey Meadowlands are located within the heavily urbanized New York/New Jersey Harbor Estuary and have been subject to contamination due to effluent and runoff from industry, traffic, and homes along the Hackensack River and nearby waterways. These extensive wetlands, though heavily impacted by development and pollution, support a wide array of bird and other wildlife species. Persistent contaminants may pose threats to birds in these habitats, affecting reproduction, egg hatchability, nestling survival, and neurobehavioral development. Metals of concern in the Meadowlands include arsenic, cadmium, chromium, lead, and mercury. These metals were analyzed in eggs, feathers, muscle, and liver of Canada geese (Branta canadensis) breeding in four wetland sites. We sampled geese collected during control culling (n=26) and collected eggs from goose nests (n=34). Levels of arsenic were below the minimum quantification level (MQL) in most samples, and cadmium and mercury were low in all tissues sampled. Chromium levels were high in feather samples. Mercury levels in eggs of Canada geese, an almost exclusively herbivorous species, were lower (mean {+-}SE 4.29{+-}0.30 {mu}g/g wet weight) than in eggs of omnivorous mallards (Anas platyrhynchos), and insectivorous red-winged blackbirds (Agelaius phoeniceus) and marsh wrens (Cistothorus palustris) from the Meadowlands, consistent with trophic level differences. However, lead levels were higher in the goose eggs (161{+-}36.7 ng/g) than in the other species. Geese also had higher levels of lead in feathers (1910{+-}386 ng/g) than those seen in Meadowlands passerines. By contrast, muscle and liver lead levels were within the range reported in waterfowl elsewhere, possibly a reflection of metal sequestration in eggs and feathers. Elevated lead levels may be the result of sediment ingestion or ingestion of lead shot and sinkers. Finally, lead levels in goose liver (249{+-}44.7 ng/g) and eggs (161{+-}36.7 ng/g) may pose a

    The stabilization of a guiding catheter is a very important factor for successful endovascular treatment. However, it is sometimes difficult to obtain sufficient stabilization because of the tortuosity of the approach route. A Goose Neck Snare is useful for the retrieval of intravascular foreign bodies and can be used to hold the guiding catheter. We describe five cases of endovascular treatment performed while using the Goose Neck Snare via the brachial artery to hold the guiding catheter. We discuss the utility of this strategy.

    Geese are capable of digesting and making use of a high-fiber diet, but the mechanism is not well understood and would be of great significance for the development and utilization of roughage resources. In this study, we investigated the effect of dietary fiber (source: corn stover and alfalfa, included at 5% or 8%) on microflora in goose intestines. We used 35-day-old Carlos geese in which we first studied the influence of fiber ingestion on diet digestibility and immune organ indices of geese and found that high dietary fiber (8% content) significantly increased feed intake, the digestibility of neutral and acid detergent fiber, and thymus, bursa, and spleen size. Subsequently, we investigated the effect of dietary fiber on the microbial flora in the various intestinal segments by high throughput sequencing. The bacterial diversity and relative abundance were significantly affected by the type and amount of dietary fiber fed, including that of cellulolytic bacteria such as Bacteroides, Ruminococcus, Clostridium, and Pseudomonas spp. Finally, we isolated and identified 8 strains with cellulolytic ability from goose intestine and then analyzed their activities in combination. The optimal combination for cellulase activity was Cerea bacillus and Pseudomonas aeruginosa. This study has laid a theoretical and practical foundation for knowledge of the efficient conversion and utilization of cellulose by geese. © 2018 Poultry Science Association Inc.

  1. A comparison of field-line resonances observed at the Goose Bay and Wick radars

    Full Text Available Previous observations with the Goose Bay HF coherent-scatter radar have revealed structured spectral peaks at ultra-low frequencies. The frequencies of these spectral peaks have been demonstrated to be extremely consistent from day to day. The stability of these spectral peaks can be seen as evidence for the existence of global magnetospheric cavity modes whose resonant frequencies are independent of latitude. Field-line resonances occur when successive harmonics of the eigenfrequency of the magnetospheric cavity or waveguide match either the first harmonic eigenfrequency of the geomagnetic field lines or higher harmonics of this frequency. Power spectra observed at the SABRE VHF coherent-scatter radar at Wick, Scotland, during night and early morning are revealed to show similarly clearly structured spectral peaks. These spectral peaks are the result of local field-line resonances due to Alfvén waves standing on magnetospheric field lines. A comparison of the spectra observed by the Goose Bay and Wick radars demonstrate that the frequencies of the field-line resonances are, on average, almost identical, despite the different latitudinal ranges covered by the two radars. Possible explanations for the similarity of the signatures on the two radar systems are discussed.

    In this study, the complete genome of the virulent strain LH of goose parvovirus (GPV) was sequenced and cloned into the pBluescript II (SK) plasmid vector. Sequence alignments of the inverted terminal repeats (ITR) of GPV strains revealed a common 14-nt-pair deletion in the stem of the palindromic structure in the LH strain and three other strains isolated after 1982 when compared to three GPV strains isolated earlier than that time. Transfection of 11-day-old embryonated goose eggs with the plasmid pLH, which contains the entire genome of strain LH, resulted in successful rescue of the infectious virus. Death of embryos after transfection via the chorioallantoic membrane infiltration route occurred earlier than when transfection was done via the allantoic cavity inoculation route. The rescued virus exhibited virulence similar to that of its parental virus, as evaluated by the mortality rate in goslings. Generation of the pathogenic infectious clone provides us with a powerful tool to elucidate the molecular pathogenesis of GPV in the future.

    Goose parvovirus (GPV) infection can cause a highly contagious and lethal disease in goslings and muscovy ducklings which is widespread in all major goose (Anser anser) and Muscovy duck (Cairina moschata) farming countries, leading to a huge economic loss. Humoral immune responses play a major role in GPV immune protection during GPV infection. However, it is still unknown for the localization and immunological characteristics of B-cell epitopes on GPV non-structural protein (NSP). Therefore, in this study, the epitopes on the NSP of GPV were identified by means of overlapping peptides expressed in Escherichia coli in combination with Western blot. The results showed that the antigenic epitopes on the GPV NSP were predominantly localized in the C-terminal (aa 485-627), and especially, the fragment NS (498-532) was strongly positive. These results may facilitate future investigations on the function of NSP of GPV and the development of immunoassays for the diagnosis of GPV infection. Copyright © 2016. Published by Elsevier B.V.

    Full Text Available Goose parvovirus (GPV and avian influenza virus subtype H9N2 are single-stranded DNA (ssDNA and single-stranded RNA (ssRNA viruses, respectively, both of which can spread in goslings and cause a significant economic loss. To explore the comprehensive transcriptome of GPV- or H9N2-infected goose spleens and to understand the immune responses induced by a DNA virus (GPV or a RNA virus (H9N2, RNA-seq was performed on the spleens of goslings at the fifth day post infection. In the present study, 2604 and 2409 differentially expressed unigenes were identified in the GPV- and H9N2-infected groups, respectively. Through KEGG pathway enrichment analyses, the up-regulated transcripts in the two virus-infected groups were mainly involved in immune-related pathways. In addition, the two virus-infected groups displayed similar expression patterns in the immune response pathways, including pattern-recognition receptor signaling pathways, the antigen processing and presentation pathway, the NF-κB signaling pathway and the JAK-STAT signaling pathway, as well as cytokines. Furthermore, most of the immune-related genes, particularly TLR7, TRAF3, Mx, TRIM25, CD4, and CD8α, increased in response to GPV and H9N2 infection. However, the depression of NF-κB signaling may be a mechanism by which the viruses evade the host immune system or a strategy to achieve immune homeostasis.

  6. Predation danger can explain changes in timing of migration: the case of the barnacle goose.

    Directory of Open Access Journals (Sweden)

    Rudy M Jonker

    Full Text Available Understanding stopover decisions of long-distance migratory birds is crucial for conservation and management of these species along their migratory flyway. Recently, an increasing number of Barnacle geese breeding in the Russian Arctic have delayed their departure from their wintering site in The Netherlands by approximately one month and have reduced their staging duration at stopover sites in the Baltic accordingly. Consequently, this extended stay increases agricultural damage in The Netherlands. Using a dynamic state variable approach we explored three hypotheses about the underlying causes of these changes in migratory behavior, possibly related to changes in (i onset of spring, (ii potential intake rates and (iii predation danger at wintering and stopover sites. Our simulations showed that the observed advance in onset of spring contradicts the observed delay of departure, whereas both increased predation danger and decreased intake rates in the Baltic can explain the delay. Decreased intake rates are expected as a result of increased competition for food in the growing Barnacle goose population. However, the effect of predation danger in the model was particularly strong, and we hypothesize that Barnacle geese avoid Baltic stopover sites as a response to the rapidly increasing number of avian predators in the area. Therefore, danger should be considered as an important factor influencing Barnacle goose migratory behavior, and receive more attention in empirical studies.

    Freshwater snail Physa acuta has been considered as an important invasive species and medical mollusc. Field investigation has shown that this snail could survive better than other snails in polluted water bodies. To understand the immune mechanisms of P. acuta, suppression subtractive hybridization hepatopancreas cDNA library has been constructed with bacterial challenge. In this study, a full-length cDNA of a novel goose-type lysozyme (PALysG) has been identified from P. acuta by EST and RACE technique. The conservative structure domains share high homology with other molluscan g-type lysozymes including the SLT domain, the substrate binding sites, the catalytic residues, three alpha-helices structures and six molluscan specific cysteines. Meanwhile, PALysG is the first record of goose-type lysozyme in Gastropoda. Real-time PCR indicated that PALysG mRNA had been expressed significantly at high levels in hepatopancreas for 8-48 h. PALysG recombinant protein displayed the lytic activity of g-type lysozyme with other organisms against Micrococcus lysodikicus. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available The retinoic acid-inducible gene I (RIG-I and the RIG-I-like receptor (RLR protein play a critical role in the interferon (IFN response during RNA virus infection. The tripartite motif containing 25 proteins (TRIM25 was reported to modify caspase activation and RIG-I recruitment domains (CARDs via ubiquitin. These modifications allow TRIM25 to interact with mitochondrial antiviral signaling molecules (MAVs and form CARD-CARD tetramers. Goose TRIM25 was cloned from gosling lungs, which possess a 1662 bp open reading flame (ORF. This ORF encodes a predicted 554 amino acid protein consisting of a B-box domain, a coiled-coil domain, and a PRY/SPRY domain. The protein sequence has 89.25% sequence identity with Anas platyrhynchos TRIM25, 78.57% with Gallus gallus TRIM25, and 46.92% with Homo sapiens TRIM25. TRIM25 is expressed in all gosling and adult goose tissues examined. QRT-PCR revealed that goose TRIM25 transcription could be induced by goose IFN-α, goose IFN-γ, and goose IFN-λ, as well as a35 s polyinosinic-polycytidylic acid (poly(I:C, oligodeoxynucleotides 2006 (ODN 2006, and resiquimod (R848 in vitro; however, it is inhibited in H9N2 infected goslings for unknown reasons. These data suggest that goose TRIM25 might play a positive role in the regulation of the antiviral immune response.

    Full Text Available The goose (Anser cygnoides, having high nutritional value, high-quality feathers and high economic benefit, is an economically important poultry species. However, the molecular mechanisms underlying the higher susceptibility to pathogens in goslings than in adult geese remains poorly understood. In this study, the histological sections of spleen tissue from a two-week-old gosling and an adult goose, respectively, were subjected to comparative analysis. The spleen of gosling was mainly composed of mesenchyma, accompanied by scattered lymphocytes, whereas the spleen parenchyma was well developed in the adult goose. To investigate goose immune-related genes, we performed deep transcriptome and gene expression analyses of the spleen samples using paired-end sequencing technology (Illumina. In total, 50,390 unigenes were assembled using Trinity software and TGICL software. Moreover, these assembled unigenes were annotated with gene descriptions and gene ontology (GO analysis was performed. Through Kyoto encyclopedia of genes and genomes (KEGG analysis, we investigated 558 important immune-relevant unigenes and 23 predicted cytokines. In addition, 22 immune-related genes with differential expression between gosling and adult goose were identified, among which the three genes showing largest differences in expression were immunoglobulin alpha heavy chain (IgH, mannan-binding lectin serine protease 1 isoform X1 (MASP1 and C–X–C chemokine receptor type 4 (CXCR4. Finally, of these 22 differentially expressed immune-related genes, seven genes, including tumor necrosis factor receptor superfamily member 13B (TNFRSF13B, C-C motif chemokine 4-like (CCL4, CXCR4, interleukin 2 receptor alpha (IL2RA, MHC class I heavy chain (MHCIα, transporter of antigen processing 2 (TAP2, IgH, were confirmed by quantitative real-time PCR (qRT-PCR.

    This trial was conducted to study the effect of full-fat rice bran inclusion in diets on growth performance, carcass and meat quality and fatty acid composition in Sichuan goose. A total of 204 Sichuan white male geese (28-d-old, 984 ± 15 g) were used in the 42-d assay. Full-fat rice bran inclusion in diets was 0%, 6%, 12% and 18%, respectively. On d 70, two geese from each pen were randomly selected and killed for measuring the carcass and meat quality and the meat fatty acid composition. The results showed that full-fat rice bran inclusion had no effect on average daily gain during 28-56 d, but rice bran inclusion at 18% increased average daily gain during 57-70 d. In addition, the full-fat rice bran supplementation decreased the subcutaneous fat yield, and the inclusion of full-fat rice bran in amounts of 12% and 18% decreased the half-eviscerated carcass yield, eviscerated carcass yield and crude fat content in goose meat. Moreover, full-fat rice bran supplementation had no effect on the content of total saturated fatty acid (SFA), but decreased the content of total monounsaturated fatty acid (MUFA). The inclusion of full-fat rice bran in amounts of 12-18% increased the content of total polyunsaturated fatty acid (PUFA) and total n-6 in goose meat and in the amount of 18% increased n-3 fatty acids content in goose meat. The results indicated that the rice bran inclusion had a positive effect in geese by stimulating growth performance and improving meat quality and fatty acid composition of goose meat.

    Kerr Hydroelectric Dam is located at the south end of Flathead Lake, controls water levels on the lake and the Flathead River below the dam, and is currently operated as a load control facility. Current operation of Kerr Dam creates the greatest yearly water level fluctuations on both the lake and river during the Canada goose (Branta canadensis moffitti) brood and nesting period. Data collected from 1980-1982 indicated that goose nest numbers on the river were lower than during the 1950's, and that brood habitat on the lake may be limiting the goose population there. Our study was conducted from 1983-1987 to determine the effects of Kerr Dam operation on Canada goose populations and habitat on the south half of Flathead Lake and the Flathead River, and to formulate management and mitigation recommendations. Nesting geese on the river appeared to be negatively affected by a lack of nest sites free from predators, and responded to available artificial nest structures with an increase in nest numbers and nesting success. Under current dam operation, river channel depths and widths do not discourage access to nesting islands by mammalian predators during some years and high predation on ground nests occurs. Intensively used brood areas on the lake and river were identified and described. Brood habitat on the lake was lower in quality and quantity than on the river due to dam operations. Gosling mortality on the lake was high, almost 2 times higher than on the river. Lake broods expended more energy obtaining food than river broods. Losses of brood habitat in the form of wet meadow marshes were documented and mitigation options developed. Management/mitigation alternatives and monitoring methods for nesting and brooding geese were identified.

    4,4'-Dinitrocarbanilide (DNC) was extracted from chicken, duck, goose, and snake eggs and isolated by reversed-phase liquid chromatography. DNC was detected by ultraviolet absorbance at 347 nm and quantitated by comparison with a calibration standard. Recoveries of DNC from fortified control chicken, duck, goose, and snake egg samples were determined for DNC levels of 0.16, 10, and 16 microg/g. The mean recoveries from chicken, duck, goose, and snake eggs were 92 +/- 4, 88 +/- 9, 87 +/- 7, and 95 +/- 6%, respectively. The method limits of detection for DNC in chicken, duck, goose, and snake eggs ranged from 0.015 to 0.035 microg/g. The reported method is much simpler than and equally efficient as previous methods developed for the determination of DNC residues in egg contents.

    The authors collected nationally representative data on Canadian residents' experiences with and perspectives on personal psychotherapy in their psychiatric training. A 43-item questionnaire was distributed electronically to all current psychiatry residents in Canada (N = 839). Four hundred residents from every program across Canada returned the survey (response rate 47.7%). The prevalence of personal therapy at any time was 55.3%, with 42.8% receiving personal therapy during residency. Of residents who undertook personal psychotherapy, 59.3% engaged in weekly therapy, 74.1% received psychodynamic psychotherapy, and 81.5% participated in long-term therapy (>1 year). Personal growth, self-understanding, and professional development were the most common reasons for engaging in personal therapy; however, one-third of residents did so to alleviate symptoms of depression, anxiety, or other mental health concerns. Time was the most important factor impeding residents from personal therapy; only 8.8% found stigma to act as a barrier. The vast majority of residents rated their experience with personal therapy as having a positive or very positive impact on their personal life (84.8%) and overall development as psychiatrists (81.8%). For 64% of respondents, personal therapy had an important or very important role in psychiatry residency training. Residents who received personal therapy rated themselves as better able to understand what happens moment by moment during therapy sessions, detect and deal with patients' emotional reactions, and constructively use their personal reactions to patients. Interest in personal therapy remains strong among psychiatry trainees in Canada. Residents who engaged in psychotherapy endorsed greater confidence in psychotherapy and rated their psychotherapy skills more favorably than those who had never been in the patient role, supporting the view of personal therapy as an important adjunct to psychotherapy training during residency.

    A spring hunt was instituted in North America to reduce abundance of snow geese (Chen caerulescens) by increasing mortality of adults directly, yet disturbance from hunting activities can indirectly influence body condition and ultimately, reproductive success. We estimated effects of hunting disturbance by comparing body composition of snow geese and non-target species, greater white-fronted geese (Anser albifrons) and northern pintails (Anas acuta) collected in portions of south-central Nebraska that were open (eastern Rainwater Basin, ERB) and closed (western Rainwater Basin, WRB; and central Platte River Valley, CPRV) to snow goose hunting during springs 1998 and 1999. Lipid content of 170 snow geese was 25% (57 g) less in areas open to hunting compared to areas closed during hunting season but similar in all areas after hunting was concluded in the ERB. Protein content of snow geese was 3% (14 g) less in the region open to hunting. Greater white-fronted geese had 24% (76 g; n = 129) less lipids in the hunted portion of the study area during hunting season, and this difference persisted after conclusion of hunting season. We found little difference in lipid or protein content of northern pintails in relation to spring hunting. Indirect effects of spring hunting may be considered a collateral benefit regarding efforts to reduce overabundant snow goose populations. Disrupted nutrient storage observed in greater white-fronted geese represents an unintended consequence of spring hunting that has potential to adversely affect reproduction for this and other species of waterbirds staging in the region.

  20. The complete mitochondrial genome of bean goose (Anser fabalis and implications for anseriformes taxonomy.

    Gang Liu

    Full Text Available Mitochondrial DNA plays an important role in living organisms, and has been used as a powerful molecular marker in a variety of evolutionary studies. In this study, we determined the complete mtDNA of Bean goose (Anser fabalis, which is 16,688 bp long and contains 13 protein-coding genes, 2 rRNAs, 22 tRNAs and a control region. The arrangement is similar to that of typical Anseriform species. All protein-coding genes, except for Cyt b, ND5, COI, and COII, start with an ATG codon. The ATG start codon is also generally observed in the 12 other Anseriform species, including 2 Anser species, with sequenced mitochondrial genomes. TAA is the most frequent stop codon, one of three-TAA, TAG, and T- -commonly observed in Anseriformes. All tRNAs could be folded into canonical cloverleaf secondary structures except for tRNA(Ser(AGY and tRNA(Leu(CUN, which are missing the dihydrouridine (DHU arm. The control region of Bean goose mtDNA, with some conserved sequence boxes, such as F, E, D, and C, identified in its central domain. Phylogenetic analysis of complete mtDNA data for 13 Anseriform species supports the classification of them into four major branches: Anatinae, Anserinae, Dendrocygninae and Anseranatidae. Phylogenetic analyses were also conducted on 36 Anseriform birds using combined Cyt b, ND2, and COI sequences. The results clearly support the genus Somateria as an independent lineage classified in its own tribe, the Somaterini. Recovered topologies from both complete mtDNA and combined DNA sequences strongly indicate that Dendrocygninae is an independent subfamily within the family Anatidae and Anseranatidae represents an independent family. Based on the results of this study, we conclude that combining ND2, Cyt b, and COI sequence data is a workable solution at present for resolving phylogenetic relationships among Anseriform species in the absence of sufficient complete mtDNA data.

    Full Text Available Circoviruses are circular single-stranded DNA (ssDNA viruses that infect a variety of animals, both domestic and wild. Circovirus infection in birds is associated with immunosuppression and this in turn predisposes the infected animals to secondary infections that can lead to mortality. Farmed geese (Anser anser in many parts of the world are infected with circoviruses. The majority of the current genomic information for goose circoviruses (GoCVs (n = 40 are from birds sampled in China and Taiwan, and only two genome sequences are available from Europe (Germany and Poland. In this study, we sampled 23 wild and 19 domestic geese from the Gopło Lake area in Poland. We determined the genomes of GoCV from 21 geese; 14 domestic Greylag geese (Anser anser, three wild Greylag geese (A. anser, three bean geese (A. fabalis, and one white fronted goose (A. albifrons. These genomes share 83–95% nucleotide pairwise identities with previously identified GoCV genomes, most are recombinants with exchanged fragment sizes up to 50% of the genome. Higher diversity levels can be seen within the genomes from domestic geese compared with those from wild geese. In the GoCV capsid protein (cp and replication associated protein (rep gene sequences we found that episodic positive selection appears to largely mirror those of beak and feather disease virus and pigeon circovirus. Analysis of the secondary structure of the ssDNA genome revealed a conserved stem-loop structure with the G-C rich stem having a high degree of negative selection on these nucleotides.

After their arrival in spring, pink-footed geese (Anser brachyrhynchus forage extensively on below-ground plant parts, using a feeding technique called grubbing that has substantial impact on the tundra vegetation. Previous studies have shown a high frequency of grubbing in lowland fen vegetation. In the present study, we examined the occurrence of grubbing in other habitat types on Spitsbergen, in the Arctic archipelago of Svalbard. Goose grubbing was surveyed along 19 altitudinal transects, going from the valley bottom to altitudes dominated by scree. Grubbing was more frequent in the wet habitat type at low altitudes compared to the drier habitat type at higher altitudes. For the dry habitat type, a higher frequency of grubbing was found in study plots with a south-east facing exposure where snowmelt is expected to be early. This suggests that pink-footed geese primarily use dry vegetation types for grubbing when they are snow-free in early spring and the availability of snow-free patches of the preferred wet vegetation types in the lowlands is limited. Dry vegetation types have poorer recovery rates from disturbance than wet ones. Sites with early snowmelt and dry vegetation types may therefore be at greater risk of long-term habitat degradation. We conclude that the high growth rate of the Svalbard-breeding pink-footed goose population suggests that increasing impacts of grubbing can be expected and argue that a responsible monitoring of the effects on the tundra ecosystem is crucial.

    Purpose: Statistics from the Canadian post-MD education registry show that numbers of Canadian radiation oncology (RO) trainees have risen from 62 in 1999 to approximately 150 per year between 2003 and 2009, contributing to the current perceived downturn in employment opportunities for radiation oncologists in Canada. When last surveyed in 2003, Canadian RO residents identified job availability as their main concern. Our objective was to survey current Canadian RO residents on their training and career plans. Methods and Materials: Trainees from the 13 Canadian residency programs using the national matching service were sought. Potential respondents were identified through individual program directors or chief resident and were e-mailed a secure link to an online survey. Descriptive statistics were used to report responses. Results: The eligible response rate was 53% (83/156). Similar to the 2003 survey, respondents generally expressed high satisfaction with their programs and specialty. The most frequently expressed perceived weakness in their training differed from 2003, with 46.5% of current respondents feeling unprepared to enter the job market. 72% plan on pursuing a postresidency fellowship. Most respondents intend to practice in Canada. Fewer than 20% of respondents believe that there is a strong demand for radiation oncologists in Canada. Conclusions: Respondents to the current survey expressed significant satisfaction with their career choice and training program. However, differences exist compared with the 2003 survey, including the current perceived lack of demand for radiation oncologists in Canada.

    We report a novel goose parvovirus (MDGPV/PT) isolated from an affected Muscovy duck in Fujian Province, China. In this study, the NS1 sequence analyses indicated a close genetic relationship between MDGPV/PT and Muscovy duck parvovirus (MDPV) strains, although MDGPV/DY, which was isolated from a Muscovy duck in 2006 in Sichuan Province, could be divided into GPV-related groups. Phylogenetic analysis showed that except for differences in the NS1 gene, MDGPV strains PT and DY are closely related to a parvovirus that infects domestic waterfowls. This is the first demonstration of recombination between goose and Muscovy duck parvoviruses in nature, and MDGPV/PT might have led to the generation of a novel waterfowl parvovirus strain circulating in Muscovy duck flocks in China.

    Iron deficiency anemia (IDA) is the most common nutritional deficiency worldwide. This deficiency could be solved by preparing stable, edible, and absorbable iron food ingredients using environmentally friendly methods. This study investigated enzymatic hydrolysis and microencapsulation process of goose blood. The physicochemical properties, stabilities of the microencapsulated goose blood hydrolysate (MGBH) and a supplement for rats with IDA were also evaluated. The results showed that the synergetic hydrolytic action of neutrase and alkaline protease significantly increased the heme-releasing efficiency. The heme was then microencapsulated using sodium caseinate, maltodextrin and carboxymethyl cellulose (CMC) as the edible wall material, and the encapsulation efficiency of the product reached 98.64%. Meanwhile, favorable thermal, storage and light stabilities were observed for the microencapsulation. It was found that MGBH can significantly improve the body weight and hematological parameters of IDA Wistar rat. Copyright © 2016 Elsevier Ltd. All rights reserved.

    To report on a new technique that increases the safety of percutaneous atrial septal defect (ASD) closure using a goose-neck snare system. ASD transcatheter closure is a widespread procedure. However, in some cases, ASDs may be large and with soft rims. In these situation, a potential risk exists for device malposition or embolization. When transesophageal echocardiography (TEE) evaluation and balloon sizing showed large defects with floppy rims the chosen Amplatzer device was implanted in a standard way. In large defects with floppy rims, before release a 5-mm goose-neck snare with its 4 Fr catheter was placed across the delivery cable and fixed to catch the screwing mechanism of implanted Amplatzer device. The delivery cable was unscrewed and the device reached its final position without any tension. If the position was considered satisfactory the device was released from the goose-neck snare. Thirteen patients had a snare-assisted ASD transcatheter closure. Median device size was 24 mm (range 14-38 mm). Retrieval or repositioning of the device using the goose-neck snare was performed in four cases: in three patients, because of device malposition after delivery cable release and in one patient, because of unsuitability of closure of a second significant defect. Furthermore, in two subjects with multiple ASDs, a second fenestration looked quite significant with the device still attached to the delivery cable while it appeared smaller after release. Snare-assisted Amplatzer ASD device placement is a new method for ASD percutaneous closure and adds safety to the procedure. © 2016 Wiley Periodicals, Inc.

  8. Elemental microchemistry, fatty acid profile and geometric morphometrics signatures of goose barnacles (Pollicipes pollicipes reveal their place of origin

    Full Text Available Seafood plays an important role in the socioeconomic, gastronomy and cultural heritage of Portuguese coastal communities. In the Iberian Peninsula, the goose barnacle Pollicipes pollicipes is the intertidal biological resource most heavily exploited by man, resulting on overexploitation of stocks. In the MPA of BNR P.pollicipes harvesting is however strictly regulated, making it a good example of marine resources management. Analytical methods able to identify the origin of goose barnacle would be an important tool to help the management of the trade. For such purpose, we investigated whether P. pollicipes have site-specific differences based on its elemental microchemistry (EM, fatty acid profile (FA and capitulum shape (CS. The analysis was performed on specimens collected from 3 sites in the BNR and 7 along a 300 km stretch of the Portuguese coast. For each individual we analysed the largest lateral shell for EM using ICP-MS, the FA content of the muscle using GC-FID, and the CS using geometric morphometrics. Discriminant function analyses (DFA for both EM and FA separately provided a high reclassification success (77.6% and 99% respectively, of cross-validated cases correctly classified, while for EM combined with FA allowed for a 100% reclassification success. DFA analysis based only on CS, revealed a low classification success (29.6%. These results show that EM and FA signatures can be a powerful tool to infer goose barnacles origin. Such “fingerprinting” approach can be used to track and identify goose barnacles origin, helping in establishing an origin certificate and increasing the potential value of biological resources from Portuguese MPAs.

    A recent epizootic outbreak, in China, of duck beak atrophy and dwarfism syndrome (BADS) was investigated using electron microscopic, genetic, and virological studies, which identified a parvovirus with a greater similarity to goose parvovirus (GPV) (97% protein homology) than to Muscovy duck parvovirus (MDPV) (90% protein homology). The new virus, provisionally designated GPV-QH15, was found to be antigenically more closely related to GPV than to MDPV in a virus neutralization assay. These findings were further supported by phylogenetic analysis showing that GPV-QH15 evolved from goose lineage parvoviruses, rather than from Muscovy duck- or other duck species-related parvoviruses. In all, two genetic lineages (GPV I and GPV II) were identified from the GPV samples analyzed, and GPV-QH15 was found to be closely clustered with two known goose-origin parvoviruses (GPVa2006 and GPV1995), together forming a distinctive GPV IIa sublineage. Finally, structural modeling revealed that GPV-QH15 and the closely related viruses GPVa2006 and GPV1995 possessed identical clusters of receptor-interacting amino acid residues in the VP2 protein, a major determinant of viral receptor binding and host specificity. Significantly, these three viruses differed from MDPVs and other GPVs at these positions. Taken together, these results suggest that GPV-QH15 represents a new variant of goose-origin parvovirus that currently circulates in ducklings and causes BADS, a syndrome reported previously in Europe. This new finding highlights the need for future surveillance of GPV-QH15 in poultry in order to gain a better understanding of both the evolution and the biology of this emerging parvovirus.

    From the early 1970s to the present, numerous cases of short beak and dwarfism syndrome (SBDS) have been reported in mule ducks from France. The animals showed strong growth retardation with smaller beak and tarsus. It was suggested that the syndrome was caused by goose parvovirus on the basis of serological investigation, but the causative agent has not been isolated and the disease has not so far been reproduced by experimental infection. The aim of the present study was to characterize the virus strains isolated from field cases of SBDS, and to reproduce the disease experimentally. Phylogenetic analysis proved that the parvovirus isolates obtained from SBDS of mule duck belonged to a distinct lineage of goose parvovirus-related group of waterfowl parvoviruses. The authors carried out experimental infections of 1-day-old, 2-week-old and 3-week-old mule ducks by the oral route with three different parvovirus strains: strain D17/99 of goose parvovirus from Derzsy's disease, strain FM of Muscovy duck parvovirus from the parvovirus disease of Muscovy ducks, and strain D176/02 isolated from SBDS of mule duck. The symptoms of SBDS of the mule duck could only be reproduced with the mule duck isolate (strain D176/02) following 1-day-old inoculation. Infection with a genetically different strain of goose parvovirus isolated from classical Derzsy's disease (D17/99) or with the Muscovy duck parvovirus strain (FM) did not cause any clinical symptoms or pathological lesions in mule ducks.

    Full Text Available The aim of our study was to evaluate the effect of overfeeding on mRNA expression levels of genes involved in lipogenesis, in order to understand the mechanism of hepatic stea - tosis in the goose. Using Landes geese (Anser anser and Sichuan White geese (Anser cygnoides as experimental animals, we quantified the mRNA expression of lipogenic genes, acetyl-CoA carboxylase-α (ACCα and fatty acid synthase (FAS, and of two transcription factors, sterol regulatory element-binding proteins- 1 (SREBP-1 and carbohydrate responsive element-binding protein (ChREBP by real-time polymerase chain reaction (RTPCR, and measured the lipid and triglyceride (TG content in the liver and the plasma level of glucose, insulin and TG. Our results indicated that compared to the control group, the overfeeding induced an increase of the lipid and TG content in the liver and also of the plasma insulin and TG concentration in both breeds. However, the plasma glucose level decreased after overfeeding in the Sichuan White goose, and there was no evident change in the Landes goose. Lastly, the mRNA expression of ACCα, FAS, SREBP-1 and ChREBP in the overfed group was lower than in the control group in both breeds. We concluded that the lipogenesis pathway plays a role in overfeeding- induced hepatic steatosis and that the decreased mRNA level of related genes may be the indicator of hepatic steatosis.

  13. Extra-pair copulation in the greater white-fronted goose

    1989-01-01

    Controlled experiments and quantitative field studies with both captive and wild waterfowl (Family Anatidae) have demonstrated that extra-pair copulations (EPCs, both forced and unforced) may be a viable alternative reproductive strategy for males (Mineau and Cooke 1979; Burns et al. 1980; Cheng et al. 1982, 1983; Afron 1985; Evarts and Williams 1987). In a review of EPCs in waterfowl, McKinney et al. (1983) stressed the need for additional information on the extent of such behavior in seemingly monogamous species of birds. Such information would increase our understanding of the extent of mixed reproductive strategies as formally hypothesized by Trivers (1972). Extra-pair copulations have been reported for only three of 22 (14%) species of geese and swans (Tribe Anserini), but are known to occur in 37 of 122 (30%) of the remaining species of waterfowl (McKinney et al. 1983, 1984; Welsh 1988). Socioecological differences between Anserini and most other anatids may provide insight into the evolution of extra-pair copulatory behavior, as male Anserini (unlike most other Anatidae) provide extensive parental care and maintain long-term pair bonds (Owen 1980, p. 76). Cuckolded male Anserini thus stand to lose more in the form of reproductive investment than other male anatids, which may invest less in a given clutch and generally have short-term pair bonds.I describe here an observation of extra-pair copulation in wild Greater White-fronted Geese (Anser albifrons frontalis). The observation is significant not only because it augments our meager documentation of this behavior within the Anserini, but it is the first observation of such behavior in a noncolonial goose (Mineau and Cooke 1979, McKinney et al. 1983). The occurrence of EPC behavior in a dispersal-nesting goose is important, as proximity to potential mates has been hypothesized as a factor possibly selecting for EPC behavior in geese (McKinney et al. 1983) and other species of monogamous birds (Gladstone 1979

    The Fish and Wildlife Program of the Northwest Power Planning Council calls for wildlife mitigation at hydroelectric projects in the Columbia River System. Beginning April, 1984, the Bonneville Power Administration funded a study of the effects of the operation of Hungry Horse and Kerr Dams on the western Canada goose (Branta canadensis moffittii) inhabitating the Flathead Valley of northwest Montana. The study was conducted by personnel of the Montana Department of Fish, Wildlife and Parks (MDFWP), to: (1) identify the size and productivity of this population, (2) identify current habitat conditions and losses of nesting and brood-rearing areas, (3) describe the effects of water level fluctuations on nesting and brood-rearing, and (4) identify mitigation alternatives to offset these effects. Annual pair and nest surveys were used to document the location and fate of goose nests. The number of known nesting attempts varied from 44 in 1984 to 108 in 1985, to 136 in 1986 and 134 in 1987. Fifty-four percent of the annual meeting nesting effort took place on elevated sites which were secure from the flooding and dewatering effects of fluctuating water levels. An average of 15 nests were found on stumps in the remnant Flathead River delta, however, an area strongly influenced by the operation of Kerr Dam. Annual nest losses to flooding and predation attributable to fluctuations caused by the dam were recorded. 53 refs., 24 figs., 35 tabs.

    Canada's fusion strategy is based on developing specialized technologies in well-defined areas and supplying these technologies to international fusion projects. Two areas are specially emphasized in Canada: engineered fusion system technologies, and specific magnetic confinement and materials studies. The Canadian Fusion Fuels Technology Project focuses on the first of these areas. It tritium and fusion reactor fuel systems, remote maintenance and related safety studies. In the second area, the Centre Canadian de fusion magnetique operates the Tokamak de Varennes, the main magnetic fusion device in Canada. Both projects are partnerships linking the Government of Canada, represented by Atomic Energy of Canada Limited, and provincial governments, electrical utilities, universities and industry. Canada's program has extensive international links, through which it collaborates with the major world fusion programs, including participation in the International Thermonuclear Experimental Reactor project

    The structure and composition of the eggshells of two commercial species (guinea fowl and greylag goose) have been studied. Thin sections and scanning electron microcopy show the similarity of the overall structure, but the relative thickness of the layers differs in these two taxa. Atomic force microscopy shows that the different layers are composed of rounded, heterogeneous granules, the diameter of which is between 50 and 100 nm, with a thin cortex. Infrared data and thermogravimetric analyses show that both eggshells are made of calcite, but differing on the quality and quantity when the organic component is considered. Chemical maps show that chemical element distribution is not uniform within a sample, and differs between the species, but with low magnesium content. Electron back scattered diffraction confirms the eggshells are calcite, but the microtexture strongly differs between the two species. Based on the chemical-structural differences, a species-specific biological control on the biomineralization is found, despite the rapid formation of an eggshell. Overall results indicate that to estimate the quality of eggshells, such as resistance to breakage, is not a straightforward process because of the high complexity of avian eggshell biomineralization.

  18. Wild mallards have more "goose-like" bills than their ancestors: a case of anthropogenic influence?

    Directory of Open Access Journals (Sweden)

    Pär Söderquist

    Full Text Available Wild populations of the world's most common dabbling duck, the mallard (Anas platyrhynchos, run the risk of genetic introgression by farmed conspecifics released for hunting purposes. We tested whether bill morphology of free-living birds has changed since large-scale releases of farmed mallards started. Three groups of mallards from Sweden, Norway and Finland were compared: historical wild (before large-scale releases started, present-day wild, and present-day farmed. Higher density of bill lamellae was observed in historical wild mallards (only males. Farmed mallards had wider bills than present-day and historical wild ones. Present-day wild and farmed mallards also had higher and shorter bills than historical wild mallards. Present-day mallards thus tend to have more "goose-like" bills (wider, higher, and shorter than their ancestors. Our study suggests that surviving released mallards affect morphological traits in wild population by introgression. We discuss how such anthropogenic impact may lead to a maladapted and genetically compromised wild mallard population. Our study system has bearing on other taxa where large-scale releases of conspecifics with 'alien genes' may cause a cryptic invasive process that nevertheless has fitness consequences for individual birds.

    A kind of bacteria secreting cellulase and showing probiotic attributes was isolated from the cecum of goose and identified as Bacillus amyloliquefaciens by analysis of 16S rRNA gene sequence and named as B. amyloliquefaciens S1. In vitro assays, the enzymatic activity of the strain was determined by the reducing-sugar method, and the proper culture conditions of producing cellulase and some properties of the cellulase were investigated. The cultural mixture of the bacteria had a high cellulase activity of 1.25 U/mL. In order to improve the utilization rate of the cellulase, some properties of the cellulase were studied. The best reaction pH of the enzymes was 7.0 and the optimum reaction temperature was 60°C. The enzyme was a kind of neutral cellulase that possessing strong resistance against heat and acidity. It showed high activity to absorbent cotton, soybean meal, and filter paper. Meanwhile, a gene encoding a kind of cellulase was cloned and prokaryotic expressed in Escherichia coli. The gene had 1500 bp in length, encoding a protein of 55 kDa, which was confirmed by SDS-PAGE and Western blotting. This study explored the possibility of degrading ability of bacteria with its probiotic attributes to enhance digestibility of the feed and gut health of animal. It also provided some basis for its further functional analysis and practical application as a microbial preparation for the breeding.

    1998-01-01

    The juvenile fish facility at Little Goose Dam is operated seasonally to collect and bypass downstream migrating smolts and keep them from passing through the turbine blades. Fish are diverted from turbines by traveling screens as they sound in the forebay to pass the dam. A small percentage of the passing fish are sampled on a daily basis to provide information on fish condition, species composition, migration timing, and size distribution. Oregon Department of Fish and Wildlife personnel perform daily fish sampling and data collection. Physical operation of the facility is the responsibility of the US Army Corps of Engineers. Data is reported to the Fish Passage Center daily by means of electronic data transfer. Funding for this project was provided through the Smolt Monitoring Program administered by the Fish Passage Center. Overall, the number of fish collected and sampled in 1996 was a reduction from the previous years of operation. The 1996 migration season was characterized by higher than average flows and greater spill frequency at the dam. It was the first year that coho salmon were obtained in the sample. The predominant species collected was steelhead with hatchery fish outnumbering wild fish by a ratio of 8:1. An increased emphasis was placed on gas bubble trauma examination and a routine, consistent effort was implemented using a protocol established by the Fish Passage Center. The objective of the gas bubble trauma (GBT) examinations was to document the relative incidence of symptoms throughout the migration season

    The New Jersey Meadowlands are located within the heavily urbanized New York/New Jersey Harbor Estuary and have been subject to contamination due to effluent and runoff from industry, traffic, and homes along the Hackensack River and nearby waterways. These extensive wetlands, though heavily impacted by development and pollution, support a wide array of bird and other wildlife species. Persistent contaminants may pose threats to birds in these habitats, affecting reproduction, egg hatchability, nestling survival, and neurobehavioral development. Metals of concern in the Meadowlands include arsenic, cadmium, chromium, lead, and mercury. These metals were analyzed in eggs, feathers, muscle, and liver of Canada geese (Branta canadensis) breeding in four wetland sites. We sampled geese collected during control culling (n=26) and collected eggs from goose nests (n=34). Levels of arsenic were below the minimum quantification level (MQL) in most samples, and cadmium and mercury were low in all tissues sampled. Chromium levels were high in feather samples. Mercury levels in eggs of Canada geese, an almost exclusively herbivorous species, were lower (mean ±SE 4.29±0.30μg/g wet weight) than in eggs of omnivorous mallards (Anas platyrhynchos), and insectivorous red-winged blackbirds (Agelaius phoeniceus) and marsh wrens (Cistothorus palustris) from the Meadowlands, consistent with trophic level differences. However, lead levels were higher in the goose eggs (161±36.7ng/g) than in the other species. Geese also had higher levels of lead in feathers (1910±386ng/g) than those seen in Meadowlands passerines. By contrast, muscle and liver lead levels were within the range reported in waterfowl elsewhere, possibly a reflection of metal sequestration in eggs and feathers. Elevated lead levels may be the result of sediment ingestion or ingestion of lead shot and sinkers. Finally, lead levels in goose liver (249±44.7ng/g) and eggs (161±36.7ng/g) may pose a risk if consumed

    Anecdotal reports suggest that some residency application essays contain plagiarized content. To determine the prevalence of plagiarism in a large cohort of residency application essays. Retrospective cohort study. 4975 application essays submitted to residency programs at a single large academic medical center between 1 September 2005 and 22 March 2007. Specialized software was used to compare residency application essays with a database of Internet pages, published works, and previously submitted essays and the percentage of the submission matching another source was calculated. A match of more than 10% to an existing work was defined as evidence of plagiarism. Evidence of plagiarism was found in 5.2% (95% CI, 4.6% to 5.9%) of essays. The essays of non-U.S. citizens were more likely to demonstrate evidence of plagiarism. Other characteristics associated with the prevalence of plagiarism included medical school location outside the United States and Canada; previous residency or fellowship; lack of research experience, volunteer experience, or publications; a low United States Medical Licensing Examination Step 1 score; and non-membership in the Alpha Omega Alpha Honor Medical Society. The software database is probably incomplete, the 10%-match threshold for defining plagiarism has not been statistically validated, and the study was confined to applicants to 1 institution. Evidence of matching content in an essay cannot be used to infer the applicant's intent and is not sensitive to variations in the cultural context of copying in some societies. Evidence of plagiarism in residency application essays is more common in international applicants but was found in those by applicants to all specialty programs, from all medical school types, and even among applicants with significant academic honors. No external funding.

    During the spring migration, the Pink-footed Goose Anser brachyrhynchus stops in mid-Norway to refuel before continuing its flight to the Svalbard breeding grounds.

    Toll-like receptors (TLRs) recognize components of pathogens and mediate the host innate immune response. TLR21 is a TLR that specifically recognizes exogenous double-stranded DNA and rapidly signals to downstream innate immune factors. This study reports the cDNA of goose TLR21 and identifies its immune characteristics. The goose TLR21 is 3161 base pairs and encodes a 975 amino acid protein. As predicted, the goose transmembrane protein TLR21 has a signal peptide, leucine-rich repeat regions, a transmembrane domain, and a Toll/interleukin-1 receptor domain. Multiple sequence alignments and phylogenetic analyses showed that goose TLR21 has homology to chicken TLR21. The tissue distribution of TLR21 suggested that it has high transcript levels in immune-associated tissues, especially in the bursa of Fabricius, the Hadrian gland, and the thymus. After challenge with agonist ODN2006 and new type gosling viral enteritis virus (NGVEV), significant induction of TLR21 production, pro-inflammatory cytokines IL-1β and IL-6, and interferons were observed in peripheral blood mononuclear cells. Both synthetic DNA (ODN2006) and viral DNA (NGVEV) can be recognized by goose TLR21, which leads to a rapid up-regulation of pro-inflammatory cytokines and anti-viral molecules. In vivo, avian influenza A virus H9N2 and NGVEV were used to infect goslings, which was followed by a significant up-regulation of TLR21 mRNA transcripts in multiple tissues of NGVEV-infected geese. In general, goose TLR21 plays an important role in binding invading pathogenic DNA viruses, which subsequently triggers an innate immune response; furthermore, it acts as a functional homologue of mammalian TLR9, as TLR21 recognizes a mammalian TLR9 agonist.

    Waterbirds breeding on the Mongolian Plateau in Central Asia must find suitable wetland areas for nesting in a semiarid region characterized by highly variable water conditions. The first systematic nesting study of a waterbird dependent on this region for breeding was conducted on the Bar-headed Goose (Anser indicus). The purpose of this study was to document Bar-headed Goose nesting locations, characterize nests and nesting strategies, and estimate daily nest survival (n = 235 nests) from eight areas of west-central Mongolia across three summers (2009–2011) using a modified Mayfield estimator. Bar-headed Goose daily nest survival ranged from 0.94 to 0.98, with a 3-year average nest success of 42.6% during incubation. Bar-headed Geese were found to primarily nest on isolated pond and lake islands as previously reported, but were also documented regularly, though less frequently, along rocky cliffs in several regions of west-central Mongolia. Daily nest survival was higher for cliff nests than for island nests. Information-theoretic models indicated that nest survival decreased with nest age and varied annually with changing environmental conditions. Results of this study suggest that while Bar-headed Geese primarily rely on nesting island sites these sites may be more susceptible to anthropogenic disturbance and predation events influenced by seasonal variation in environmental conditions, and that higher daily nest survival values documented for the less frequent cliff nest strategy may provide an important alternative strategy during poor island nest success years. Thus, conservation efforts for this and other waterbird species in the semiarid region should be focused on conserving nesting islands and protecting them from disturbance in areas of high livestock densities experiencing a rapidly warming climate.

    4,4'-Dinitrocarbanilide (DNC) was extracted from chicken, duck, and goose plasma and isolated by reversed-phase high-performance liquid chromatography. DNC was detected by ultraviolet absorbance at 347 nm and quantified by comparison to a calibration standard. Recovery data were determined by analyzing DNC-fortified control plasma. The mean recovery of DNC in fortified chicken plasma samples was 99.7 +/- 1.9% for 0.18 and 9.1 ppm DNC, and in fortified duck and goose plasma samples was 99.5 +/- 4.9% and 101.4 +/- 4.5%, respectively, for 0.18, 9.1, and 18 ppm DNC.

  10. Two goose-type lysozymes in Mytilus galloprovincialis: possible function diversification and adaptive evolution.

    Directory of Open Access Journals (Sweden)

    Qing Wang

    Full Text Available Two goose-type lysozymes (designated as MGgLYZ1 and MGgLYZ2 were identified from the mussel Mytilus galloprovincialis. MGgLYZ1 mRNA was widely expressed in the examined tissues and responded sensitively to bacterial challenge in hemocytes, while MGgLYZ2 mRNA was predominately expressed and performed its functions in hepatopancreas. However, immunolocalization analysis showed that both these lysozymes were expressed in all examined tissues with the exception of adductor muscle. Recombinant MGgLYZ1 and MGgLYZ2 could inhibit the growth of several Gram-positive and Gram-negative bacteria, and they both showed the highest activity against Pseudomonas putida with the minimum inhibitory concentration (MIC of 0.95-1.91 µM and 1.20-2.40 µM, respectively. Protein sequences analysis revealed that MGgLYZ2 had lower isoelectric point and less protease cutting sites than MGgLYZ1. Recombinant MGgLYZ2 exhibited relative high activity at acidic pH of 4-5, while MGgLYZ1 have an optimum pH of 6. These results indicated MGgLYZ2 adapted to acidic environment and perhaps play an important role in digestion. Genomic structure analysis suggested that both MGgLYZ1 and MGgLYZ2 genes are composed of six exons with same length and five introns, indicating these genes were conserved and might originate from gene duplication during the evolution. Selection pressure analysis showed that MGgLYZ1 was under nearly neutral selection while MGgLYZ2 evolved under positive selection pressure with three positively selected amino acid residues (Y(102, L(200 and S(202 detected in the mature peptide. All these findings suggested MGgLYZ2 perhaps served as a digestive lysozyme under positive selection pressure during the evolution while MGgLYZ1 was mainly involved in innate immune responses.

  12. Effects of Water Levels on Productivity of Canada Geese in the Northern Flathead Valley, 1985 Annual Report.

    Energy Technology Data Exchange (ETDEWEB)

    Casey, Daniel

    1986-04-01

    Operation of Hungry Horse Dam on the South Fork Flathead River causes sporadic water level fluctuations along the main stem Flathead River. Changes in chronology of seasonal water level fluctuations and substantial habitat losses have occurred as a result of construction and operation of Kerr Dam, which regulates Flathead Lake. These fluctuations may impact goose populations through flooding and erosion of nesting and brood-rearing habitats, and increased susceptibility of nests and young to predation. The number, location, and success of goose nests were determined through pair surveys and nest searches. Our 1985 pair count data indicated that 95 to 143 nests may have been present. Hatching success for 1985 nests (55%) was low compared to long-term averages for the region. Predation was the predominant cause of ground nest failure (25 nests); we documented 2 nest failures due to flooding. The maximum gosling count in the study area for 1985 was 197. Six key brood-rearing areas were identified. Most (80%) sites were located in the herbaceous or pasture cover type and the riparian bench landform. Analysis of aerial photographs taken prior to construction of Kerr Dam documented the loss of 1859 acres of habitat along the north shore of Flathead Lake. Losses were attributed to inundation and to continuing erosion due to operation of Kerr Dam. Lake and river water level regimes were compared with the chronology of important periods in the nesting cycle. Low lake levels in May and early June coincide with the breed-rearing period. Mudflats are heavily used by broods, but their effect on survival must still be documented. Preliminary recommendations to protect and enhance Canada goose habitat and production are being developed.

    Recent reviews identified the reliance on fecal or cloacal samples as a significant limitation hindering our understanding of the avian gastrointestinal (gut) microbiota and its function. We investigated the microbiota of the esophagus, duodenum, cecum, and colon of a wild urban population of Canada goose (Branta canadensis). From a population sample of 30 individuals, we sequenced the V4 region of the 16S SSU rRNA on an Illumina MiSeq and obtained 8,628,751 sequences with a median of 76,529 per sample. These sequences were assigned to 420 bacterial OTUs and a single archaeon. Firmicutes, Proteobacteria, and Bacteroidetes accounted for 90% of all sequences. Microbiotas from the four gut regions differed significantly in their richness, composition, and variability among individuals. Microbial communities of the esophagus were the most distinctive whereas those of the colon were the least distinctive, reflecting the physical downstream mixing of regional microbiotas. The downstream mixing of regional microbiotas was also responsible for the majority of observed co-occurrence patterns among microbial families. Our results indicate that fecal and cloacal samples inadequately represent the complex patterns of richness, composition, and variability of the gut microbiota and obscure patterns of co-occurrence of microbial lineages.

  17. Illuminating Our World: An Essay on the Unraveling of the Species Problem, with Assistance from a Barnacle and a Goose

    Directory of Open Access Journals (Sweden)

    John Buckeridge

    2012-10-01

    Full Text Available In order to plan for the future, we must understand the past. This paper investigates the manner in which both naturalists and the wider community view one of the most intriguing of all questions: what makes a species special? Consideration is given to the essentialist view—a rigid perspective and ancient, Aristotelian perspective—that all organisms are fixed in form and nature. In the middle of the 19th century, Charles Darwin changed this by showing that species are indeed mutable, even humans. Advances in genetics have reinforced the unbroken continuum between taxa, a feature long understood by palaeontologists; but irrespective of this, we have persisted in utilizing the ‘species concept’—a mechanism employed primarily to understand and to manipulate the world around us. The vehicles used to illustrate this journey in perception are the barnacle goose (a bird, and the goose barnacle (a crustacean. The journey of these two has been entwined since antiquity—in folklore, religion, diet and even science.

    Full Text Available This 2014 roundtable discussion, hosted by the Canadian Association of General Surgeons, brought together general surgeons and gastroenterologists with expertise in endoscopy from across Canada to discuss the state of endoscopy in Canada. The focus of the roundtable was the evaluation of the competence of general surgeons at endoscopy, reviewing quality assurance parameters for high-quality endoscopy, measuring and assessing surgical resident preparedness for endoscopy practice, evaluating credentialing programs for the endosuite and predicting the future of endoscopic services in Canada. The roundtable noted several important observations. There exist inadequacies in both resident training and the assessment of competency in endoscopy. From these observations, several collaborative recommendations were then stated. These included the need for a formal and standardized system of both accreditation and training endoscopists.

    A significant barrier to accessing healthcare in Canada is long waiting lists, which can be linked to the way that Medicare was structured. After significant pressure, provincial governments began to address wait times. An example of a successful strategy to reduce wait times for elective surgery is the Saskatchewan Surgical Initiative, which saw wait times in the province change from being among the longest in Canada to the shortest.

  3. Uranium in Canada

    International Nuclear Information System (INIS)

    1985-09-01

    In 1974 the Minister of Energy, Mines and Resources (EMR) established a Uranium Resource Appraisal Group (URAG) within EMR to audit annually Canada's uranium resources for the purpose of implementing the federal government's uranium export policy. A major objective of this policy was to ensure that Canadian uranium supplies would be sufficient to meet the needs of Canada's nuclear power program. As projections of installed nuclear power growth in Canada over the long term have been successively revised downwards (the concern about domestic security of supply is less relevant now than it was 10 years ago) and as Canadian uranium supply capabilities have expanded significantly. Canada has maintained its status as the western world's leading exporter of uranium and has become the world's leading producer. Domestic uranium resource estimates have increased to 551 000 tonnes U recoverable from mineable ore since URAG completed its last formal assessment (1982). In 1984, Canada's five primary uranium producers employed some 5800 people at their mining and milling operations, and produced concentrates containing some 11 170 tU. It is evident from URAG's 1984 assessment that Canada's known uranium resources, recoverable at uranium prices of $150/kg U or less, are more than sufficient to meet the 30-year fuelling requirements of those reactors that are either in opertaion now or committed or expected to be in-service by 1995. A substantial portion of Canada's identified uranium resources, recoverable within the same price range, is thus surplus to Canadian needs and available for export. Sales worth close to $1 billion annually are assured. Uranium exploration expenditures in Canada in 1983 and 1984 were an estimated $41 million and $35 million, respectively, down markedly from the $128 million reported for 1980. Exploration drilling and surface development drilling in 1983 and 1984 were reported to be 153 000 m and 197 000 m, respectively, some 85% of which was in

  5. The Regulation of Lipid Deposition by Insulin in Goose Liver Cells Is Mediated by the PI3K-AKT-mTOR Signaling Pathway.

    Directory of Open Access Journals (Sweden)

    Chunchun Han

    Full Text Available We previously showed that the fatty liver formations observed in overfed geese are accompanied by the activation of the PI3K-Akt-mTOR pathway and an increase in plasma insulin concentrations. Recent studies have suggested a crucial role for the PI3K-Akt-mTOR pathway in regulating lipid metabolism; therefore, we hypothesized that insulin affects goose hepatocellular lipid metabolism through the PI3K-Akt-mTOR signaling pathway.Goose primary hepatocytes were isolated and treated with serum-free media supplemented with PI3K-Akt-mTOR pathway inhibitors (LY294002, rapamycin, and NVP-BEZ235, respectively and 50 or 150 nmol/L insulin.Insulin induced strong effects on lipid accumulation as well as the mRNA and protein levels of genes involved in lipogenesis, fatty acid oxidation, and VLDL-TG assembly and secretion in primary goose hepatocytes. The stimulatory effect of insulin on lipogenesis was significantly decreased by treatment with PI3K-Akt-mTOR inhibitors. These inhibitors also rescued the insulin-induced down-regulation of fatty acid oxidation and VLDL-TG assembly and secretion.These findings suggest that the stimulatory effect of insulin on lipid deposition is mediated by PI3K-Akt-mTOR regulation of lipogenesis, fatty acid oxidation, and VLDL-TG assembly and secretion in goose hepatocytes.

    Full Text Available Abstract Background Despite the critical importance of well-being during residency training, only a few Canadian studies have examined stress in residency and none have examined well-being resources. No recent studies have reported any significant concerns with respect to perceived stress levels in residency. We investigated the level of perceived stress, mental health and understanding and need for well-being resources among resident physicians in training programs in Alberta, Canada. Methods A mail questionnaire was distributed to the entire resident membership of PARA during 2003 academic year. PARA represents each of the two medical schools in the province of Alberta. Results In total 415 (51 % residents participated in the study. Thirty-four percent of residents who responded to the survey reported their life as being stressful. Females reported stress more frequently than males (40% vs. 27%, p Residents highly valued their colleagues (67%, program directors (60% and external psychiatrist/psychologist (49% as well-being resources. Over one third of residents wished to have a career counselor (39% and financial counselor (38%. Conclusion Many Albertan residents experience significant stressors and emotional and mental health problems. Some of which differ among genders. This study can serve as a basis for future resource application, research and advocacy for overall improvements to well-being during residency training.

  7. Light Goose Conservation Order effects on nontarget waterfowl behavior and energy expenditure

    2016-01-01

    When the Light Goose Conservation Order (LGCO) was established during 1999 in the Rainwater Basin of Nebraska, USA, LGCO activities were limited to 4 days/week and 16 public wetlands were closed to the LGCO to limit disturbance to nontarget waterfowl during this energetically important time period. However, the effects of LGCO activities on waterfowl behavior and energy expenditure are relatively unknown in this critical waterfowl staging area. To evaluate LGCO effects on target and nontarget species, we paired wetlands open and closed to LGCO and recorded waterfowl behavior and hunter encounters during springs 2011 and 2012. We constructed hourly energy expenditure models based on behavior data collected for mallards (Anas platyrhynchos) and northern pintails (A. acuta). In 2011, dabbling ducks (Anas spp.) spent more time feeding and less time resting in wetlands closed to hunting during early season when the majority of hunting encounters occurred; behaviors did not differ between hunt categories during late season when hunting activities subsided. However, in 2012, dabbling ducks spent more time feeding and less time resting in wetlands open to hunting during early and late seasons. We detected no differences in behaviors of lesser snow geese (Chen caerulescens) or greater white-fronted geese (Anser albifrons) between hunting categories in early season. Mallards had slightly greater energy expenditure on wetlands closed to hunting (  = 38.94 ± 0.31 kJ/bird/hr), compared with wetlands open to hunting (  = 37.87 ± 0.32 kJ/bird/hr); therefore, greater energy spent by mallards cannot be attributed to hunting disturbance. We also detected no differences in dabbling duck behavior or energy expenditure between days open or closed to hunting in the region. A refuge system of wetlands closed to LGCO activities in the Rainwater Basin may be an important management strategy in providing reduced disturbance for nontarget waterfowl species in some

    2012-08-01

    Surgery training programs in Canada and the United States have recognized the need to modify current models of training and education. The shifting demographic of surgery trainees, lifestyle issues and an increased trend toward subspecialization are the major influences. To guide these important educational initiatives, a contemporary profile of Canadian general surgery residents and their impressions of training in Canada is required. We developed and distributed a questionnaire to residents in each Canadian general surgery training program, and residents responded during dedicated teaching time. In all, 186 surveys were returned for analysis (62% response rate). The average age of Canadian general surgery residents is 30 years, 38% are women, 41% are married, 18% have dependants younger than 18 years and 41% plan to add to or start a family during residency. Most (87%) residents plan to pursue postgraduate education. On completion of training, 74% of residents plan to stay in Canada and 49% want to practice in an academic setting. Almost half (42%) of residents identify a poor balance between work and personal life during residency. Forty-seven percent of respondents have appropriate access to mentorship, whereas 37% describe suitable access to career guidance and 40% identify the availability of appropriate social supports. Just over half (54%) believe the stress level during residency is manageable. This survey provides a profile of contemporary Canadian general surgery residents. Important challenges within the residency system are identified. Program directors and chairs of surgery are encouraged to recognize these challenges and intervene where appropriate.

  9. Uranium in Canada

    International Nuclear Information System (INIS)

    1987-09-01

    Canadian uranium exploration and development efforts in 1985 and 1986 resulted in a significant increase in estimates of measured uranium resources. New discoveries have more than made up for production during 1985 and 1986, and for the elimination of some resources from the overall estimates, due to the sustained upward pressure on production costs and the stagnation of uranium prices in real terms. Canada possesses a large portion of the world's uranium resources that are of current economic interest and remains the major focus of inter-national uranium exploration activity. Expenditures for uranium exploration in Canada in 1985 and 1986 were $32 million and $33 million, respectively. Although much lower than the $130 million total reported for 1979, expenditures for 1987 are forecast to increase. Exploration and surface development drilling in 1985 and 1986 were reported to be 183 000 m and 165σ2 000 m, respectively, 85 per cent of which was in Saskatchewan. Canada has maintained its position as the world's leading producer and exporter of uranium. By the year 2000, Canada's annual uranium requirements will be about 2 100 tU. Canada's known uranium resources are more than sufficient to meet the 30-year fuel requirements of those reactors in Canada that are either in operation now or expected to be in service by the late 1990s. A substantial portion of Canada's identified uranium resources is thus surplus to Canadian needs and available for export. Annual sales currently approach $1 billion, of which exports account for 85 per cent. Forward domestic and export contract commitments totalled 73 000 tU and 62 000 tU, respectively, as of early 1987

  10. Uncertainty, robustness, and the value of information in managing an expanding Arctic goose population

    Johnson, Fred A.; Jensen, Gitte H.; Madsen, Jesper; Williams, Byron K.

    2014-01-01

    We explored the application of dynamic-optimization methods to the problem of pink-footed goose (Anser brachyrhynchus) management in western Europe. We were especially concerned with the extent to which uncertainty in population dynamics influenced an optimal management strategy, the gain in management performance that could be expected if uncertainty could be eliminated or reduced, and whether an adaptive or robust management strategy might be most appropriate in the face of uncertainty. We combined three alternative survival models with three alternative reproductive models to form a set of nine annual-cycle models for pink-footed geese. These models represent a wide range of possibilities concerning the extent to which demographic rates are density dependent or independent, and the extent to which they are influenced by spring temperatures. We calculated state-dependent harvest strategies for these models using stochastic dynamic programming and an objective function that maximized sustainable harvest, subject to a constraint on desired population size. As expected, attaining the largest mean objective value (i.e., the relative measure of management performance) depended on the ability to match a model-dependent optimal strategy with its generating model of population dynamics. The nine models suggested widely varying objective values regardless of the harvest strategy, with the density-independent models generally producing higher objective values than models with density-dependent survival. In the face of uncertainty as to which of the nine models is most appropriate, the optimal strategy assuming that both survival and reproduction were a function of goose abundance and spring temperatures maximized the expected minimum objective value (i.e., maxi–min). In contrast, the optimal strategy assuming equal model weights minimized the expected maximum loss in objective value. The expected value of eliminating model uncertainty was an increase in objective value

  11. A guide to multi-objective optimization for ecological problems with an application to cackling goose management

    Williams, Perry J.; Kendall, William L.

    2017-01-01

    Choices in ecological research and management are the result of balancing multiple, often competing, objectives. Multi-objective optimization (MOO) is a formal decision-theoretic framework for solving multiple objective problems. MOO is used extensively in other fields including engineering, economics, and operations research. However, its application for solving ecological problems has been sparse, perhaps due to a lack of widespread understanding. Thus, our objective was to provide an accessible primer on MOO, including a review of methods common in other fields, a review of their application in ecology, and a demonstration to an applied resource management problem.A large class of methods for solving MOO problems can be separated into two strategies: modelling preferences pre-optimization (the a priori strategy), or modelling preferences post-optimization (the a posteriori strategy). The a priori strategy requires describing preferences among objectives without knowledge of how preferences affect the resulting decision. In the a posteriori strategy, the decision maker simultaneously considers a set of solutions (the Pareto optimal set) and makes a choice based on the trade-offs observed in the set. We describe several methods for modelling preferences pre-optimization, including: the bounded objective function method, the lexicographic method, and the weighted-sum method. We discuss modelling preferences post-optimization through examination of the Pareto optimal set. We applied each MOO strategy to the natural resource management problem of selecting a population target for cackling goose (Branta hutchinsii minima) abundance. Cackling geese provide food security to Native Alaskan subsistence hunters in the goose's nesting area, but depredate crops on private agricultural fields in wintering areas. We developed objective functions to represent the competing objectives related to the cackling goose population target and identified an optimal solution

  13. Impacts of Canada's uranium mining industry

    International Nuclear Information System (INIS)

    Holman, G.J.

    1982-05-01

    This study examines economic and environmental impacts of uranium mining in Canada and compares these impacts with those of other extractive and energy industries. The uranium industry generates taxes and royalties, income, employment, foreign exchange earnings, security of energy supply, and technological spinoffs. The indirect impacts of the industry as measured by employment and income multipliers are lower than those for other types of mining and comparable to oil and gas because of the high proportion of costs withdrawn from the economy in the form of taxes and operator margin. Social costs are primarily occupational hazards. Uranium mining probably has a lower non-health environmental impact than other mining industries due to much smaller throughputs and transportation requirements. Residents of the area surrounding the mine bear a disproportionate share of the social costs, while non-residents receive most of the benefits

    Cardiovascular disease is among the leading causes of mortality and morbidity in Canada. Cardiac rehabilitation (CR) has a long robust history here, and there are established clinical practice guidelines. While the effectiveness of CR in the Canadian context is clear, only 34% of eligible patients participate, and strategies to increase access for under-represented groups (e.g., women, ethnic minority groups) are not yet universally applied. Identified CR barriers include lack of referral and physician recommendation, travel and distance, and low perceived need. Indeed there is now a national policy position recommending systematic inpatient referral to CR in Canada. Recent development of 30 CR Quality Indicators and the burgeoning national CR registry will enable further measurement and improvement of the quality of CR care in Canada. Finally, the Canadian Association of CR is one of the founding members of the International Council of Cardiovascular Prevention and Rehabilitation, to promote CR globally. PMID:24607018

    To become culturally competent practitioners with the ability to care and advocate for vulnerable populations, residents must be educated in global health priorities. In the field of obstetrics and gynaecology, there is minimal information about global women's health (GWH) education and interest within residency programs. We wished to determine within obstetrics and gynaecology residency programs across Canada: (1) current GWH teaching and support, (2) the importance of GWH to residents and program directors, and (3) the level of interest in a national postgraduate GWH curriculum. We conducted an online survey across Canada of obstetrics and gynaecology residency program directors and senior obstetrics and gynaecology residents. Of 297 residents, 101 (34.0%) responded to the survey and 76 (26%) completed the full survey. Eleven of 16 program directors (68.8%) responded and 10/16 (62.5%) provided complete responses. Four of 11 programs (36.4%) had a GWH curriculum, 2/11 (18.2%) had a GWH budget, and 4/11 (36.4%) had a GWH chairperson. Nine of 10 program directors (90%) and 68/79 residents (86.1%) felt that an understanding of GWH issues is important for all Canadian obstetrics and gynaecology trainees. Only 1/10 program directors (10%) and 11/79 residents (13.9%) felt that their program offered sufficient education in these issues. Of residents in programs with a GWH curriculum, 12/19 (63.2%) felt that residents in their program who did not undertake an international elective would still learn about GWH, versus only 9/50 residents (18.0%) in programs without a curriculum (P education is important for all trainees and is currently insufficient. There is a high level of interest in a national postgraduate GWH educational module.

    To select the molecular genetic markers related to egg performance of Wanjiang white goose, prolactin receptor gene (PRLR) was adopted to be a candidate gene in our study. Five pairs of primers (P1-P5) were designed to detect the SNPs of PRLR gene by PCR-SSCP method. The results revealed that polymorphisms were discovered in the PCR products amplified with P4 primers in PRLR exon 10, three genotypes were found: AA, AB and AC. The sequence of AB genotype is the same as original sequence (DQ660982) in NCBI. There are five mutations in AA genotype: C→A at 840 bp, C→T at 862 bp, T→C at 875 bp, T→A at 963 bp, A→T at 989 bp, resulting in amino acid mutations: His→Asn, Thr→Ile, Asn→Lys, Thr→Ser, and synonymous mutation at 875 bp. Sequencing revealed five mutations in AC genotype: G→T at 816 bp, A→T at 861 bp, C→T at 862 bp, T→C at 875 bp, A→G at 948 bp, causing amino acid mutations of Val→Phe, Thr→Phe, synonymous mutations at 875 and 963 bp. Besides, there are an N-glycosylation site (NQSR), three casein kinase II phosphorylation sites including SIIE, SKTE, and SLMD in AA genotype; three casein kinase II phosphorylation sites including SIIE, SKTE, and TLMD in AB genotype; three casein kinase II phosphorylation sites including SIFE, SKTE, and TLMD in AC genotype. The annual egg yielding of AB genotype geese are significantly more than those of AA and AC genotype geese on the average (Pegg performance in Wanjiang white goose.

  6. Uranium in Canada

    International Nuclear Information System (INIS)

    1989-01-01

    In 1988 Canada's five uranium producers reported output of concentrate containing a record 12,470 metric tons of uranium (tU), or about one third of total Western world production. Shipments exceeded 13,200 tU, valued at $Cdn 1.1 billion. Most of Canada's uranium output is available for export for peaceful purposes, as domestic requirements represent about 15 percent of production. The six uranium marketers signed new sales contracts for over 11,000 tU, mostly destined for the United States. Annual exports peaked in 1987 at 12,790 tU, falling back to 10,430 tU in 1988. Forward domestic and export contract commitments were more than 70,000 tU and 60,000 tU, respectively, as of early 1989. The uranium industry in Canada was restructured and consolidated by merger and acquisition, including the formation of Cameco. Three uranium projects were also advanced. The Athabasca Basin is the primary target for the discovery of high-grade low-cost uranium deposits. Discovery of new reserves in 1987 and 1988 did not fully replace the record output over the two-year period. The estimate of overall resources as of January 1989 was down by 4 percent from January 1987 to a total (measured, indicated and inferred) of 544,000 tU. Exploration expenditures reached $Cdn 37 million in 1987 and $59 million in 1988, due largely to the test mining programs at the Cigar Lake and Midwest projects in Saskatchewan. Spot market prices fell to all-time lows from 1987 to mid-1989, and there is little sign of relief. Canadian uranium production capability could fall below 12,000 tU before the late 1990s; however, should market conditions warrant output could be increased beyond 15,000 tU. Canada's known uranium resources are more than sufficient to meet the 30-year fuel requirements of those reactors in Canada that are now or are expected to be in service by the late 1990s. There is significant potential for discovering additional uranium resources. Canada's uranium production is equivalent, in

    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.

    1984-01-01

    Kidneys from 309 Interior Canada geese from three locations in the Mississippi Flyway were examined for renal coccidia. Oocysts and/or young zygotes of Eimeria sp. were found in 6.8% of goose kidneys sampled. Only one type of renal coccidian oocyst was observed. Significantly more immature geese were infected than adults; however, there was no significant difference observed between the prevalences of infection in male and female birds. A host cellular response to zygotes and oocysts was noted in the majority of infected adult geese. Heavily infected kidneys were hypertrophic with minute foci on the surface of the organ. Histological examinations showed large numbers of unsporulated oocysts accumulated in distended collecting tubules, resulting in pressure necrosis to adjacent tissue and urate retention. Zygotes were observed in the cytoplasm of tubule cells and extracellularly in interstitial tissue. Infected tubule cells were characterized by the peripheral location of the nuclei, cytoplasmic basophilia, and cellular hypertrophy. This is the first report of an Eimeria sp. in the kidneys of Canada geese of the Mississippi Valley population.

    2016-11-01

    The 2013 pan-Canadian consensus Report on Resident Duty Hours identified that traditional 24-hour duty periods pose risks to the well-being of residents and should be avoided. In anticipation of duty-hour restrictions, the Obstetrics and Gynaecology Residency Program at the University of Toronto developed and implemented a night float (NF) call model over a three-year span. Quarterly resident surveys have consistently shown that the NF system is preferred to traditional 24-hour call and has resulted in reduced fatigue and improved continuity of patient care. Through many iterations, the NF model achieved levels of resident morale, surgical experience, and impact on family relationships that are comparable to the 24-hour call system. We review here our process for developing an NF call model and the perceptions and experiences of residents, with the goal of providing insight for other residency programs that are considering or instituting NF call systems.

    The case study is an analysis of the legal, institutional, and financial incentives and obstacles to the development of the hydroelectric potential on the Goose River in Maine. The Goose River project concerns development by a private developer, Maine Hydro-Electric Development Corporation. The project is comprised of a five-dam system, with the first dam located at Swan Lake and the fifth dam about one mile from the sea. It will utilize the 7500 acre-feet of storage capacity of Swan Lake to run the four downstream power stations. The system is designed to generate 430 kWs of total capacity which would be sold to Central Maine Power, the local investor-owned public utility.

    Real time quantitative polymerase chain reaction (RT-qPCR) based on SYBR-Green I binding is a quick, reliable, and easy method for analyzing small amounts of mRNA. Viral pathogens are recognized at the time of infection by pattern recognition receptors; thus, the inflammatory cytokines (IL1β, IL6, and IL18) and antiviral cytokines (IFNα, IFNγ) are secreted by innate immune cells and induced to respond to the pathogens. The objective of this study was to develop an effective and sensitive RT-qPCR assay for the rapid and accurate quantification of goose cytokines: IFNα, IFNγ, IL1β, IL6, and IL18. Subsequently, the established methods were employed to detect the immune response in agonist-stimulated goose spleen cells in vitro. These data indicated that the established RT-qPCR is a reliable method for determining relative gene expression. The results revealed that Imiquimod led to the significant upregulation of goose IFNα (P pathogens. © 2015 Poultry Science Association Inc.

    2007-01-01

    Curbing the proliferation of biological weapons (BW) is an essential element of the Global Partnership Against the Spread of Weapons and Materials of Mass Destruction. At the Kananaskis Summit in June 2002, G8 Leaders committed to prevent terrorists, or those that harbour them, from acquiring or developing biological weapons and related materials, equipment and technology. To this end, Canada's Global Partnership Program is investing heavily in biological non-proliferation activities in countries of the former Soviet Union. A comprehensive strategy has been developed to help improve biological safety (biosafety) and biological security (biosecurity) with provision for addressing dual-use concerns. Raising awareness and creating a self-sustaining culture of biosecurity is a key driver of the program. Through this strategy, Canada is assisting various FSU countries to: develop and implement effective and practical biosafety/biosecurity standards and guidelines; establish national and/or regional biosafety associations; develop and deliver effective biosafety and biosecurity training; put in place enhanced physical security measures and equipment. In addition to biosafety and biosecurity, the GPP supports a broad range of Biological Non-Proliferation projects and initiatives, including dozens of projects aimed at redirecting former biological weapons scientists. To date, most of these activities have been supported through Canada's contribution to the International Science and Technology Center (ISTC) and the Science and Technology Centre Ukraine (STCU).(author)

  20. Canada's reactor exports

    International Nuclear Information System (INIS)

    Morrison, R.W.

    1981-01-01

    A brief sketch of the development of Canada's nuclear exports is presented and some of the factors which influence the ability to export reactors have been identified. The potential market for CANDUs is small and will develop slowly. The competition will be tough. There are few good prospects for immediate export orders in the next two or three years. Nonetheless there are reasonable opportunities for CANDU exports, especially in the mid-to-late 1980s. Such sales could be of great benefit to Canada and could do much to sustain the domestic nuclear industry. Apart from its excellent economic and technical performance, the main attraction of the CANDU seems to be the autonomy it confers on purchasing countries, the effectiveness with which the associated technology can be transferred, and the diversification it offers to countries which wish to reduce their dependence on the major industrial suppliers. Each sales opportunity is unique, and marketing strategy will have to be tailored to the customer's needs. Over the next decade, the factors susceptible to Canadian government action which are most likely to influence CANDU exports will be the political commitment of the government to those reactor exports, the performance established by the four 600 MWe CANDUs now nearing completion, the continuing successful operation of the nuclear program in Ontario, and the co-ordination of the different components of Canada's nuclear program (AECL, nuclear industry, utilities, and government) in putting forth a coherent marketing effort and following through with effective project management

    2016-02-01

    This article is part of a special series on midwifery education and describes the approach to midwifery education in Canada We begin with an overview of the model of midwifery practice introduced in Canada in the 1990s. We describe the model of midwifery education developed and report how it is implemented, with particular attention to the two longest established programs. Midwifery education programs in Ontario and British Columbia. Midwifery education programs in Canada are offered at the undergraduate baccalaureate level at universities and are typically four years in length. Programs are competence-based and follow a spiral curriculum. The first semesters focus on on core sciences, social sciences and introduction to midwifery concepts. Students spend fifty percent of the program in clinical practices with community-based midwives. Innovative education models enable students to be placed in distant placements and help to align theoretical and practice components. Clinically active faculty adds to the credibility of teaching but bring its own challenges for midwifery educators. The Canadian model of midwifery education has been very effective with low attrition rates and high demand for the number of places available. Further program expansion is warranted but is contingent on the growth of clinical placements. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Nursing residents may experience physical and emotional exhaustion from the daily life of attending the Program. The aim of this study was to determine the Burnout incidence among Nursing Residents. An investigative, descriptive, analytical, longitudinal-prospective study was conducted with 16 Residents over two years. The Maslach Burnout Inventory was used, translated and validated for Brazil, as well as a sociodemographic/occupational data tool. Of all residents, 17.2% showed high rates in Emotional Exhaustion and Depersonalization; 18.8% showed impaired commitment in Personal Accomplishment, 75% of which belonged to specialty areas, such as Emergency Nursing, Adult and Pediatric Intensive Care. Age and specialty area were positively correlated with Personal Accomplishment. One of the Residents was identified with changes in three subscales of the Maslach Burnout Inventory, thus characterized as a Burnout Syndrome patient. Nursing Residents have profiles of disease. Knowing these factors can minimize health risks of these workers.

    To evaluate the current state of abortion training in Canadian Obstetrics and Gynecology residency programs. Surveys were distributed to all Canadian Obstetrics and Gynecology residents and program directors. Data were collected on inclusion of abortion training in the curriculum, structure of the training and expected competency of residents in various abortion procedures. We distributed and collected surveys between November 2014 and May 2015. In total, 301 residents and 15 program directors responded, giving response rates of 55% and 94%, respectively. Based on responses by program directors, half of the programs had "opt-in" abortion training, and half of the programs had "opt-out" abortion training. Upon completion of residency, 66% of residents expected to be competent in providing first-trimester surgical abortion in an ambulatory setting, and 35% expected to be competent in second-trimester surgical abortion. Overall, 15% of residents reported that they were not aware of or did not have access to abortion training within their program, and 69% desired more abortion training during residency. Abortion training in Canadian Obstetrics and Gynecology residency programs is inconsistent, and residents desire more training in abortion. This suggests an ongoing unmet need for training in this area. Policies mandating standardized abortion training in obstetrics and gynecology residency programs are necessary to improve delivery of family planning services to Canadian women. Abortion training in Canadian Obstetrics and Gynecology residency programs is inconsistent, does not meet resident demand and is unlikely to fulfill the Royal College of Physicians and Surgeons of Canada objectives of training in the specialty.

    Psychosomatic medicine (PM) is recognized as a psychiatric subspecialty in the US, but continues to be considered a focused area of general psychiatric practice in Canada. Due to the unclear status of PM in Canada, a national survey was designed to assess the perception of and training experiences in PM among psychiatry residents. Residents enrolled at one of 13 psychiatry programs in Canada participated in the study. Logistic regression analyses were conducted to assess the effect of PM training experiences and career interest in PM on the perception of PM, controlling for number of months already completed in PM, training level, and residency program. The response rate was 35%, n = 199. 68% of respondents identified PM as a definite subspecialty, with the majority of respondents believing that PM was as important a subspecialty as child (53%), forensic (67%) and geriatric psychiatry (75%). Eighty percent of the respondents believed a PM specialist should complete more than 3 months of additional training to be competent/qualified. There was significant heterogeneity in training experiences across programs, with a differential effect of certain training components-seminar, journal club-associated with a more favorable perception of PM as a subspecialty. The above results challenge the notion that PM represents only a focused area of general psychiatric practice in Canada. PM appears to require additional training beyond residency for trainees to feel competent and qualified. Results from this survey suggest Canada should follow the US lead on recognizing PM as a subspecialty. Copyright © 2011 The Academy of Psychosomatic Medicine. Published by Elsevier Inc.

  5. Antiviral Biologic Produced in DNA Vaccine/Goose Platform Protects Hamsters Against Hantavirus Pulmonary Syndrome When Administered Post-exposure.

    Directory of Open Access Journals (Sweden)

    Nicole Haese

    Full Text Available Andes virus (ANDV and ANDV-like viruses are responsible for most hantavirus pulmonary syndrome (HPS cases in South America. Recent studies in Chile indicate that passive transfer of convalescent human plasma shows promise as a possible treatment for HPS. Unfortunately, availability of convalescent plasma from survivors of this lethal disease is very limited. We are interested in exploring the concept of using DNA vaccine technology to produce antiviral biologics, including polyclonal neutralizing antibodies for use in humans. Geese produce IgY and an alternatively spliced form, IgYΔFc, that can be purified at high concentrations from egg yolks. IgY lacks the properties of mammalian Fc that make antibodies produced in horses, sheep, and rabbits reactogenic in humans. Geese were vaccinated with an ANDV DNA vaccine encoding the virus envelope glycoproteins. All geese developed high-titer neutralizing antibodies after the second vaccination, and maintained high-levels of neutralizing antibodies as measured by a pseudovirion neutralization assay (PsVNA for over 1 year. A booster vaccination resulted in extraordinarily high levels of neutralizing antibodies (i.e., PsVNA80 titers >100,000. Analysis of IgY and IgYΔFc by epitope mapping show these antibodies to be highly reactive to specific amino acid sequences of ANDV envelope glycoproteins. We examined the protective efficacy of the goose-derived antibody in the hamster model of lethal HPS. α-ANDV immune sera, or IgY/IgYΔFc purified from eggs, were passively transferred to hamsters subcutaneously starting 5 days after an IM challenge with ANDV (25 LD50. Both immune sera, and egg-derived purified IgY/IgYΔFc, protected 8 of 8 and 7 of 8 hamsters, respectively. In contrast, all hamsters receiving IgY/IgYΔFc purified from normal geese (n=8, or no-treatment (n=8, developed lethal HPS. These findings demonstrate that the DNA vaccine/goose platform can be used to produce a candidate antiviral

  9. Transnational surrogacy: Canada's contradictions.

    Science.gov (United States)

    Lozanski, Kristin

    2015-01-01

    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.

    The situation of the energy supply of Canada is characterized by its geographic location and by the dispersal of the energy consumers over a wide area. At present, the energy supply leaving the successful CANDU nuclear energy programme out of account, is based mainly on crude oil, natural gas, and electricity as well as on coal imported from the USA. The targets of Canadian enery policies and energy research are stated as follows: a) Reducing and optimizing energy consumption, b) introducing district heating, and c) utilizing the extensive local coal deposits.

    More than 15,000 line-km of new regional seismic reflection and refraction data in the western Arctic Ocean provide insights into the tectonic and sedimentologic history of Canada Basin, permitting development of new geologic understanding in one of Earth's last frontiers. These new data support a rotational opening model for southern Canada Basin. There is a central basement ridge possibly representing an extinct spreading center with oceanic crustal velocities and blocky basement morphology characteristic of spreading centre crust surrounding this ridge. Basement elevation is lower in the south, mostly due to sediment loading subsidence. The sedimentary succession is thickest in the southern Beaufort Sea region, reaching more than 15 km, and generally thins to the north and west. In the north, grabens and half-grabens are indicative of extension. Alpha-Mendeleev Ridge is a large igneous province in northern Amerasia Basin, presumably emplaced synchronously with basin formation. It overprints most of northern Canada Basin structure. The seafloor and sedimentary succession of Canada Basin is remarkably flat-lying in its central region, with little bathymetric change over most of its extent. Reflections that correlate over 100s of kms comprise most of the succession and on-lap bathymetric and basement highs. They are interpreted as representing deposits from unconfined turbidity current flows. Sediment distribution patterns reflect changing source directions during the basin’s history. Initially, probably late Cretaceous to Paleocene synrift sediments sourced from the Alaska and Mackenzie-Beaufort margins. This unit shows a progressive series of onlap unconformities with a younging trend towards Alpha and Northwind ridges, likely a response to contemporaneous subsidence. Sediment source direction appeared to shift to the Canadian Arctic Archipelago margin for the Eocene and Oligocene, likely due to uplift of Arctic islands during the Eurekan Orogeny. The final

  14. Psychologic effects of residency.

    The intense situational and physiologic stresses that accompany postgraduate training may have serious psychosocial ramifications. Although only a small proportion of residents have overt psychiatric illness, virtually all display some psychologic impairment. Contributing factors include life-changes, stresses associated with providing patient care, loss of social support, long working hours, sleep deprivation, and underlying personality traits of residents. The manifestations of this impairment are variable and may be subtle. In response to these problems, residency programs have taken steps to provide psychosocial support. Unfortunately, most programs do not offer formal support groups or seminars to discuss difficulties that accompany residency. Further definition of the psychosocial effects of residency may prompt changes that make the training of physicians a more humane process.

    Climate change and human activities cause uncertain changes to species biodiversity by altering their habitat. The uncertainty of climate change requires planners to balance the benefit and cost of making conservation plan. Here optimal protection approach for Lesser White-fronted Goose (LWfG) by coupling Modern Portfolio Theory (MPT) and Marxan selection were proposed. MPT was used to provide suggested weights of investment for protected area (PA) and reduce the influence of climatic uncertainty, while Marxan was utilized to choose a series of specific locations for PA. We argued that through combining these two commonly used techniques with the conservation plan, including assets allocation and PA chosing, the efficiency of rare bird's protection would be enhanced. In MPT analyses, the uncertainty of conservation-outcome can be reduced while conservation effort was allocated in Hunan, Jiangxi and Yangtze River delta. In Marxan model, the optimal location for habitat restorations based on existing nature reserve was identified. Clear priorities for the location and allocation of assets could be provided based on this research, and it could help decision makers to build conservation strategy for LWfG.

    2012-01-01

    Groundwater, surface water, and soil in the Goose Lake oil field in northeastern Montana have been affected by Cl−-rich oil-field brines during long-term petroleum production. Ongoing multidisciplinary geochemical and geophysical studies have identified the degree and local extent of interaction between brine and groundwater. Fourteen samples representing groundwater, surface water, and brine were collected for Sr isotope analyses to evaluate the usefulness of 87Sr/86Sr in detecting small amounts of brine. Differences in Sr concentrations and 87Sr/86Sr are optimal at this site for the experiment. Strontium concentrations range from 0.13 to 36.9 mg/L, and corresponding 87Sr/86Sr values range from 0.71097 to 0.70828. The local brine has 168 mg/L Sr and a 87Sr/86Sr value of 0.70802. Mixing relationships are evident in the data set and illustrate the sensitivity of Sr in detecting small amounts of brine in groundwater. The location of data points on a Sr isotope-concentration plot is readily explained by an evaporation-mixing model. The model is supported by the variation in concentrations of most of the other solutes.

  17. Splicing of goose parvovirus pre-mRNA influences cytoplasmic translation of the processed mRNA

    Li, Long; Pintel, David J., E-mail: pinteld@missouri.edu

    2012-04-25

    Translation of goose parvovirus (GPV) 72 kDa Rep 1 is initiated from unspliced P9-generated mRNAs in ORF1 from the first in-frame AUG (537 AUG); however, this AUG is bypassed in spliced P9-generated RNA: translation of the 52 kDa Rep 2 protein from spliced RNA is initiated in ORF2 at the next AUG downstream (650 AUG). Usage of the 537 AUG was restored in spliced RNA when the GPV intron was replaced with a chimeric SV40 intron, or following specific mutations of the GPV intron which did not appear in the final spliced mRNA. Additionally, 650 AUG usage was gained in unspliced RNA when the GPV intron splice sites were debilitated. Splicing-dependent regulation of translation initiation was mediated in cis by GPV RNA surrounding the target AUGs. Thus, nuclear RNA processing of GPV P9-generated pre-mRNAs has a complex, but significant, effect on alternative translation initiation of the GPV Rep proteins.

    With the current absence of scientific information on the nutritive aspects it is essential to investigate the fatty acid, mineral, and amino acid composition of Egyptian geese as well as the factors of influence. The forage vs. grain based diets of Egyptian geese during certain periods of the yr leads to variation in the content of the key fatty acids such as oleic acid, linoleic acid, and α-linolenic acid. The differences in these fatty acids results in variation between the n-6/n-3 ratios of the seasons; the portions from winter (July) are within the recommendations (ratio acids. No substantial differences were found in the mineral composition of the breast portion on account of season and gender; however there were some variation in certain amino acids such as lysine and arginine due to season/diet. This research provides essential information that should be considered not only regarding the everyday consumption of Egyptian goose meat but the potential utilization and ultimate consistency of this meat product. © 2015 Poultry Science Association Inc.

    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.

    This paper provided an outline of Canada's Clean Air Act and examined some of the regulatory changes that will occur as a result of its implementation. The Act is being introduced to strengthen the legislative basis for taking action on reducing air pollution and GHGs, and will allow the government to regulate both indoor and outdoor air pollutants and GHGs. The Act will require the Ministers of the Environment and Health to establish national air quality objectives, as well as to monitor and report on their attainment. The Canadian Environmental Protection Act will be amended to enable the government to regulate the blending of fuels and their components. The Motor Vehicle Fuel Consumption Standards Act will also be amended to enhance the government's authority to regulate vehicle fuel efficiency. The Energy Efficiency Act will also be expanded to allow the government to set energy efficiency standards and labelling requirements for a wider range of consumer and commercial products. The Act will commit to short, medium and long-term industrial air pollution targets. Regulations will be proposed for emissions from industry; on-road and off-road vehicles and engines; and consumer and commercial products. It was concluded that the Government of Canada will continue to consult with provinces, territories, industries and Canadians to set and reach targets for the reduction of both indoor and outdoor air pollutants and GHG emissions. 6 figs

    1980-12-01

    Canada's historical energy consumption, its current consumption and its likely requirements by the turn of the century are reviewed. It is estimated that at least 50% more energy will be required in the year 2000 than is consumed now, assuming a minimum 2% growth rate in primary energy consumption. Both non-renewable and renewable energy resources are examined in the light of these future energy requirements and the need to substitute alternative energy sources for conventional oil in various end uses. The comparative risks involved in energy production are also reviewed. Most of the increase in energy consumption and the substitution of oil over the next 20 years is likely to be met by conventional energy sources, since indigenous reserves are extensive and the relevant technologies well-established. Coal, nuclear and hydro reserves could cover the increase in energy demand until well into the next century, and natural gas reserves are sufficient to bridge the gap during conversion from oil to other energy sources. Nuclear power using advanced fuel cycles and oil from tar sands offer Canada long-term security. The penetration of unconventional energy sources is likely to be relatively small during the next 20 years. However, the most promising may become significant in the next century. (author)

    Currently, general surgeons provide about 50% of endoscopy services across Canada and an even greater proportion outside large urban centres. It is essential that endoscopy remain a core component of general surgery practice and a core competency of general surgery residency training. The Canadian Association of General Surgeons Residents Committee supports the position that quality endoscopy training for all Canadian general surgery residents is in the best interest of the Canadian public. However, the means by which quality endoscopy training is achieved has not been defined at a national level. Endoscopy training in Canadian general surgery residency programs requires standardization across the country and improved measurement to ensure that competency and basic credentialing requirements are met.

    During the first half of June, heavy rains inundated northern Minnesota and southern Canada, giving rise to floods that drove hundreds of people from their homes and drenched more than 300,000 acres of prime farmland. This false-color image of the flood (right) was acquired on June 15, 2002, by the Moderate-resolution Imaging Spectroradiometer (MODIS), flying aboard NASA's Terra spacecraft. The worst of the flooding occurred on the border of Canada and Minnesota along the Roseau River, which now resembles a lake in the center of the image. The town of Roseau, Minnesota, which sits in the eastern end of the newly formed lake, was hit the hardest. Nearly all the buildings in the town took heavy water damage and many residents were forced to leave. Widespread flooding across an eight county region in Minnesota has drenched nearly 300,000 to 500,000 acres of farmland altogether. Many of the farmers hit lost 100 percent of their crops and will be unable to plant again for the season. Last week, President Bush declared northern Minnesota a disaster area. Normally, the Roseau River cannot even be seen on a MODIS image (left, acquired May 21, 2002), and the surrounding area is dry.

    2013-03-01

    Research projects are a key component of pharmacy residents' education. Projects represent both a large investment of effort for each resident (up to 10 weeks over the residency year) and a large body of research (given that there are currently over 150 residency positions in Canada annually). Publication of results is a vital part of the dissemination of information gleaned from these projects. To determine the publication rate for research projects performed under the auspices of accredited English-language hospital pharmacy residency programs in Canada and to describe the study characteristics of residency projects performed in Ontario from 1999/2000 to 2008/2009. Lists of residents and project titles for the period of interest were obtained from residency coordinators. PubMed, CINAHL, the Canadian Journal of Hospital Pharmacy, and Google were searched for evidence of publication of each project identified, as an abstract or presentation at a meeting, a letter to the editor, or a full-text manuscript. The library holdings of the University of Toronto were reviewed to determine study characteristics of the Ontario residency projects. For the objective of this study relating to publication rate, 518 projects were included. The overall publication rate was 32.2% (60 [35.9%] as abstracts and 107 [64.1%] as full-text manuscripts). Publication in pharmacy-specific journals (66 [61.7%] of 107 full-text manuscripts) was more frequent than publication in non-pharmacy-specific journals. The publication rate of projects as full-text manuscripts remained stable over time. Of the 202 Ontario residency projects archived in the University of Toronto's library, most were cohort studies (83 [41.1%]), and the most common topic was efficacy and/or safety of a medication (46 [22.8%]). Most hospital pharmacy residents' projects were unpublished, and the publication rate of projects as full-text manuscripts has not increased over time. Most projects were observational studies

    1995-01-01

    Canadian tritium activites comprise three major interests: utilites, light manufacturers, and fusion. There are 21 operating CANDU reactors in Canada; 19 with Ontario Hydro and one each with Hydro Quebec and New Brunswick Power. There are two light manufacturers, two primary tritium research facilities (at AECL Chalk River and Ontario Hydro Technologies), and a number of industry and universities involved in design, construction, and general support of the other tritium activities. The largest tritum program is in support of the CANDU reactors, which generate tritium in the heavy water as a by-product of normal operation. Currently, there are about 12 kg of tritium locked up in the heavy water coolant and moderator of these reactors. The fusion work is complementary to the light manufacturing, and is concerned with tritium handling for the ITER program. This included design, development and application of technologies related to Isotope Separation, tritium handling, (tritiated) gas separation, tritium-materials interaction, and plasma fueling

  14. Western Canada uranium perspective

    1984-01-01

    The current situation in the exploration for uranium in British Columbia, the Yukon, the Northwest Territories, and Saskatchewan is reviewed. A moratorium on exploration has been in effect in British Columbia since 1980; it is due to expire in 1987. Only the Blizzard deposit appears to have any economic potential. The Lone Gull discovery in the Thelon Basin of the Northwest Territories has proven reserves of more than 35 million pounds U 3 O 8 grading 0.4%. Potentially prospective areas of the northern Thelon Basin lie within a game sanctuary and cannot be explored. Exploration activity in Saskatchewan continues to decline from the peak in 1980. Three major deposits - Cluff Lake, Rabbit Lake and Key Lake - are in production. By 1985 Saskatchewan will produce 58% of Canada's uranium, and over 13% of the western world's output. (L.L.)

    The literature concerning local opposition to wind turbine developments has relatively few case studies exploring the felt impacts of people living with turbines in their daily lives. Aitken even suggests that such residents are subtly or overtly cast as deviants in the current literature. Our mixed-methods, grounded-theory case study of two communities in Ontario, Canada provides insights about such residents though twenty-six face-to-face in-depth interviews, 152 questionnaires, and basic s...

    The proper culture conditions for producing cellulase of Bacillus amyloliquefaciens S1, isolated from the cecum of goose was optimized by single-factor experiment combined with orthogonal test. The properties of the cellulase were investigated by DNS method. The appropriate doses of B. amyloliquefaciens S1 were obtained by adding them to goose feed. It indicated that the suitable culture conditions of producing cellulase were the culture temperature of 37°C, the initial pH of 7.0, the incubation time of 72 h and the loaded liquid volume of 75 ml per 250 ml. The effects of each factor on producing cellulase by B. amyloliquefaciens S1 were as follows: initial pH > incubation time = culture temperature > loaded liquid volume. The optimum reaction temperature and pH were 50°C and 7.0, respectively. This enzyme is a kind of neutral cellulase that possesses resistance to heat and acidity. It showed high activity to absorbent cotton, soya bean meal and filter paper. By adding different doses of B. amyloliquefaciens S1 to the goose feed, it was found that the egg production, average egg weight, fertilization rate and the hatching rate were promoted both in experiment 1 (1.5 g kg−1) and experiment 2 (3 g kg−1). Also the difference of egg production, fertilization rate and hatching rate between experiment 1 and control group was obvious (p < 0.05), and the average egg weight was significantly increased in experiment 2 (p < 0.05).

    The level of work satisfaction among pharmacists in ASHP-accredited residencies was studied. In March 1996 a questionnaire designed to measure residency satisfaction was mailed to 697 individuals in ASHP-accredited pharmacy practice and specialty practice residencies. Subjects responded to 16 statements relating to intrinsic and extrinsic determinants of work satisfaction on a scale of 1 to 5, where 1 = strongly disagree and 5 = strongly agree. Questionnaires were returned by 413 (59%) of the residents. The respondents were predominantly women (76%), and most (86%) had at least a Pharm. D. degree. Hospitals were the primary work setting (88%). Of the 413 residents, 305 were in pharmacy practice residencies and 108 were in specialized residencies. None of the mean scores indicated disagreement (scores 3) with the negatively worded statements. The median and mode were equal to 2 (disagree) for the three negatively worded items and 4 (agree) for all but three positively worded items. Only 8% of the residents indicated that they would not accept the residency again if given the chance. Specialized residents tended to rate positively worded statements higher and negatively worded statements lower than pharmacy practice residents. Female residents indicated greater satisfaction than male residents. Pay and benefits were rated slightly better than neutral. Pharmacy residents appeared generally satisfied with their residencies. Specialized pharmacy residents were more satisfied than pharmacy practice residents, and women were more satisfied than men.

    The present study investigates the use of a mark–resight procedure to estimate total population size in a local goose population. Using colour-ring sightings of the increasingly scattered population of Light-bellied Brent Geese Branta bernicla hrota from their Danish staging areas, we estimate...... a total population size of 7845 birds (95% CI: 7252–8438). This is in good agreement with numbers obtained from total counts, emphasizing that this population, although steadily increasing, is still small compared with historic numbers....

  20. Croatian Language Maintenance in Canada

    2017-01-01

    factors to be examined concern the absolute number of community members, their geographical distribution, the number of Croatian language speakers, and the number of those with Croatian as their mother tongue. According to the 2011 census, there were 114 880 Canadians of Croatian origin, representing an increase of 3.5% over 2006. In 2006, 110 880 Canadian residents reported Croatian ancestry, representing a percentage change of 12.5% from 2001. In 2001, there were 97 050 Canadians who self-identified as being of Croatian origin, representing a percentage change of 13% from 1996, when there were 84 495 Canadians of Croatian origin. Furthermore, census data show that the percentage of Canadians of Croatian origin reporting multiple ethnicity increased over the period; in 1996, there were 65.5% single ethnic origin responses, compared to 60% in 2001, 50.9% in 2006, and only 45.1% in 2011. In terms of geographical distribution of members of Croatian community in Canada, almost two thirds of all Canadians of Croatian descent (74 020 live in the province Ontario, with significant numbers also in British Columbia (19 855 and Alberta (10 055. The largest Croatian community is in the Toronto area, where 35 115 Croatians live, with significant numbers also in Vancouver (13 025 and Hamilton (11 640. The census data presented here indicate that demographic factors that positively influence Croatian language maintenance are the size of the linguistic group and geographic concentration of the group. More precisely, the absolute number of people of Croatian descent living in Canada is on the rise and the population of Croatian origin is mostly concentrated in the province of Ontario and in major urban centers in other provinces. On the other hand, the rise in the percentage of Canadians of Croatian descent reporting more than one ancestry could be viewed as a factor that negatively affects Croatian language maintenance. It is provided by the evidence of gradually changing marriage

    The aim of this study is identified the degree of Burnout Syndrome (BOS) and find out its correlation with years of recidency and sociodemograpfic chareacteristics, training, sleeping habits, such as smoking and alcohol consumption. After approval from the Hospital Ethics Committee and obtaining informed consent, First, second, third, fourth and fifth year of recidency staff (n=127) working in our hospital were involved in this study. The standardized Maslach Burnout Inventory (MBI) was used in this study. Fifty six male (44.1%) and seventy one female (55.9%) residents were enroled in this study (Coranbach Alfa(α)=0.873). 57% of the first year residents smokes cigaret and 54% of them use alcohol. 2% of them gets one day off after hospital night shift, 61% of them suffers from disturbed sleep. 60% of them had been stated that they willingly selected their profession. 61% of them prefers talking to friends and 32% of them prefers shopping to overcome stress. There were statistical difference acording to years of recidency in MBI, Emotional Burnout (EB) and desensitisation scale (DS) points. EB scale points of the second year of residency group was statisticaly higher than fourth year of residency group. DS points of second year of residency group was also statisticaly higher than the third and fourth year of residency group. There was no statistical difference between any groups in Personal Success. BOS is a frequent problem during residency in anaesthesia. Appropriate definition and awareness are the first important steps to prevent this syndrome. Further administrative approaches should be evaluated with regard to their effects.

    Canada has for the fifth time in a row been chosen the best industrialized country in the world in which to initiate and run a business. The Norwegian interest in Canada has grown strongly the last years and Norwegian companies have invested over 20 billion NOK there. Canada is the perfect gateway to the large markets in the USA. Norway is currently Canada's 15th largest trading partner. In addition to low costs and strategic location, Canada has the most highly educated workforce in the world. A company on the Canadian side of the US border has the same access to the American market as a US-based company. There is even a Norwegian company in Canada that exports 100 per cent of its products across the border to the USA. The trade between the USA and Canada is more extensive than between the USA and all the EU countries together. Furthermore, Canadian companies concentrating on research and education are given a generous tax credit

    Full text: Full text: Canada has been the world leader in uranium production since the early 1990's and production in 2005 was 11,629 te U. The Elliott Lake region of Ontario was once the centre of production, but after the last facilities closed in 1996, all production now comes from the Athabasca Basin in northern Saskatchewan. Average grades of the world's two largest high grade deposits at McArthur River and Cigar Lake are 10 to 100 times the grade of deposits mined elsewhere. McArthur River has been in production since late 1999 and first production from Cigar Lake is expected in 2007. If all expansion and probable mine openings come to fruition, annual Canadian production could amount to 16,000 te U by 2011. All currently operating uranium mines have been the subject of a comprehensive environmental assessment and review process. Uranium mining brings significant benefits to local area residents in northern Saskatchewan. Residents of northern Saskatchewan are active participants in Environmental Quality Committees. Recent survey results show the majority of Saskatchewan residents support the continuation of uranium mining in the province. The closed uranium mines in Canada have been successfully decommissioned and rehabilitated in particular in the Elliott Lake region of Ontario. The principle exploration target in Canada remains the Athabasca Basin, but activity has also been reported in several of the other territories and provinces. Natural Resources Canada estimates that some $CAN81M was spent on exploration in Canada in 2005. Under the Canadian Constitution, natural resources are owned by the provinces or by the federal government if they are on federal lands north of 60 0 C latitude. The provinces have jurisdiction over exploration activities within their borders and for most commodities have jurisdiction over mine development and production, operations, health and safety and environmental matters.

    To examine Canadian family medicine residents' perspectives surrounding teaching opportunities and mentorship in teaching. A 16-question online survey. Canadian family medicine residency programs. Between May and June 2011, all first- and second-year family medicine residents registered in 1 of the 17 Canadian residency programs as of September 2010 were invited to participate. A total of 568 of 2266 residents responded. Demographic characteristics, teaching opportunities during residency, and resident perceptions about teaching. A total of 77.7% of family medicine residents indicated that they were either interested or highly interested in teaching as part of their future careers, and 78.9% of family medicine residents had had opportunities to teach in various settings. However, only 60.1% of respondents were aware of programs within residency intended to support residents as teachers, and 33.0% of residents had been observed during teaching encounters. It appears that most Canadian family medicine residents have the opportunity to teach during their residency training. Many are interested in integrating teaching as part of their future career goals. Family medicine residencies should strongly consider programs to support and further develop resident teaching skills.

    With so much invested in the clinical competency of physicians, adequate and appropriate mechanisms are needed to ensure that educational systems provide the highest-quality training possible and are responsive both to the changing demands of the patient population and to changing technologies and research. After a literature review, the authors concluded that there are no established criteria or principles, from a learners' perspective, that set out goals for the delivery and evaluation in Canada of quality postgraduate medical education. The authors initiated the process of developing a set of principles of medical education based on residents' perspectives by compiling a list of issues and concepts that were felt to be important to creating the "ideal" postgraduate medical education system. This list of issues was divided into broad categories before presentation by the authors for Canada-wide discussion, reflection, and further refinement of concepts and issues across a nine-month period. The process eventually resulted in the final consensus-driven and iterative development of the main categories and the final principles that were adopted by the Canadian Association of Internes and Residents (CAIR). The authors present this set of principles and propose that they be used as a template to guide postgraduate medical education and against which changes to the system can be evaluated. CAIR will use these principles in a number of ways, including evaluation, education, and quality assurance.

    1992-01-01

    The nuclear industry in Canada comprises three identifiable groups: (1) Atomic Energy of Canada Limited (AECL), (2) electrical utilities that use nuclear power plants, (3) private engineering and manufacturing companies. At the end of World War II, AECL was charged with investigating and developing peaceful uses of atomic power. Included in the results is the Canada deuterium uranium (CANDU) reactor, a peculiarly Canadian design. The AECL maintains research capability and operates as the prime nuclear steam supply system supplier. Utilities in three Canadian provinces operate nuclear power plants, New Brunswick, Quebec, and Ontario, with the majority in Ontario. From the beginning of the nuclear program in Canada, private industry has been an important partner to AECL and the utilities, filling roles as manufacturing subcontractors and as component designers. The prime objective of this paper is to illuminate the role of private industry in developing and maintaining a competitive world-class nuclear industry

    Curriculum and role modeling adjustments are necessary to address patient safety gaps occurring during dermatology residency. To identify the source of clinical practices among dermatology residents that affect patient safety and determine the best approach for overcoming gaps in knowledge and practice patterns that contribute to these practices. A survey-based study, performed at a national medical dermatology meeting in Itasca, Illinois, in 2012, included 142 dermatology residents from 44 residency programs in the United States and Canada. Self-reported rates of dermatology residents committing errors, identifying local systems errors, and identifying poor patient safety role modeling. Of surveyed dermatology residents, 45.2% have failed to report needle-stick injuries incurred during procedures, 82.8% reported cutting and pasting a previous author's patient history information into a medical record without confirming its validity, 96.7% reported right-left body part mislabeling during examination or biopsy, and 29.4% reported not incorporating clinical photographs of lesions sampled for biopsy in the medical record at their institution. Residents variably perform a purposeful pause ("time-out") when indicated to confirm patient, procedure, and site before biopsy, with 20.0% always doing so. In addition, 59.7% of residents work with at least 1 attending physician who intimidates the residents, reducing the likelihood of reporting safety issues they witness. Finally, 78.3% have witnessed attending physicians purposefully disregarding required safety steps. Our data reinforce the need for modified curricula, systems, and teacher development to reduce injuries, improve communication with patients and between physicians, residents, and other members of the health care team, and create an environment free of intimidation.

    Full Text Available Background: Pediatric health research is important for improving the health and well-being of children and their families. To foster the development of physicians’ research competencies, it is vital to integrate practical and context-specific research training into residency programs. Purpose: To describe the development of a resident research training program at one tertiary care pediatric academic health sciences center in Ontario, Canada. Methods: We surveyed residents and pediatricians/research staff to establish the need and content for a resident research training program. Results: Residents and resident research supervisors agreed or strongly agreed that research training is important for residents. However, few residents and supervisors believed that their academic health sciences center provided adequate training and resources to support resident research. As such, an online resident research training program was established. Residents and supervisors agreed that the program should focus on the following topics: 1 critically evaluating research literature, 2 writing a research proposal, 3 submitting an application for research funding, and 4 writing a manuscript. Discussion: This highly accessible, context-specific, and inexpensive online program model may be of interest and benefit to other residency programs as a means to enhance residents’ scholarly roles. A formal evaluation of the research training program is now underway.

    Muscovy duck parvovirus (MDPV) is the etiological agent of Muscovy duckling parvoviral disease, which is characterized by diarrhea, locomotive dysfunction, stunting, and death in young ducklings, and causes substantial economic losses in the Muscovy duck industry worldwide. FZ91-30 is an attenuated vaccine strain that is safe and immunogenic to ducklings, but the genomic information and molecular mechanism underlining the attenuation are not understood. The FZ91-30 strain was propagated in 11-day-old embryonated goose eggs, and viral particles were purified from the pooled allantoic fluid by differential centrifugation and ultracentrifugation. Single-stranded genomic DNA was extracted and annealed to form double-stranded DNA. The dsDNA digested with NcoI resulted two sub-genomic fragments, which were then cloned into the modified plasmid pBluescript II SK, respectively, generating plasmid pBSKNL and pBSKNR. The sub-genomic plasmid clones were sequenced and further combined to construct the plasmid pFZ that contained the entire genome of strain FZ91-30. The complete genome sequences of strain FM and YY and partial genome sequences of other strains were retrieved from GenBank for sequence comparison. The plasmid pFZ containing the entire genome of FZ91-30 was transfected in 11-day-old embryonated goose eggs via the chorioallantoic membranes route to rescue infectious virus. A genetic marker was introduced into the rescued virus to discriminate from its parental virus. The genome of FZ91-30 consists of 5,131 nucleotides and has 98.9 % similarity to the FM strain. The inverted terminal repeats (ITR) are 456 nucleotides in length, 14 nucleotides longer than that of Goose parvovirus (GPV). The exterior 415 nucleotides of the ITR form a hairpin structure, and the interior 41 nucleotides constitute the D sequence, a reverse complement of the D' sequence at the 3' ITR.

    Resident fatigue has become a point of emphasis in medical education and its effects on otolaryngology residents and their patients require further study. The purpose of our study was to evaluate the prevalence and nature of fatigue in otolaryngology residents, evaluate various quality of life measures, and investigate associations of increased fatigue with resident safety. Anonymous survey. Internet based. United States allopathic otolaryngology residents. None. The survey topics included demographics, residency structure, sleep habits and perceived stress. Responses were correlated with a concurrent Epworth Sleep Scale questionnaire to evaluate effects of fatigue on resident training and quality of life. 190 residents responded to the survey with 178 completing the Epworth Sleep Scale questionnaire. Results revealed a mean Epworth Sleep Scale score of 9.9±5.1 with a median of 10.0 indicating a significant number of otolaryngology residents are excessively sleepy. Statistically significant correlations between Epworth Sleep Scale and sex, region, hours of sleep, and work hours were found. Residents taking in-house call had significantly fewer hours of sleep compared to home call (p=0.01). Residents on "head and neck" (typically consisting of a large proportion of head and neck oncologic surgery) rotations tended to have higher Epworth Sleep Scale and had significantly fewer hours of sleep (p=.003) and greater work hours (potolaryngology residents are excessively sleepy. Our data suggest that the effects of fatigue play a role in resident well-being and resident safety. Copyright © 2016 Elsevier Inc. All rights reserved.

    Current petroleum industry activities on Canada's east coast, and future potential were discussed. Offshore drilling activity is proceeding in the Jeanne d'Arc Basin, in addition to the Sable and Terra Nova Offshore Energy Projects. Future potential for Newfoundland and Nova Scotia has been estimated at 30 billion BOE and 13 billion BOE respectively. Natural gas potential off Labrador was estimated at 37 Tcf, offshore Newfoundland at 41 Tcf, and offshore Sable Island at 49 Tcf with varying amounts of oil associated with each field. Cumulative industry spending is expected to reach $ 10 billion by the year 2000, and could reach $20 billion by 2005. Prospects for Mobil Oil, number One in discoveries and industry influence, and number Two in acreage among the partners, were reviewed. Some details of the Sable Offshore Energy Project were outlined. The estimated cost of the project is $2 billion. It is expected to be on stream in late 1999 with a total of 27 wells (11 in phase 1). Reserves are estimated at 3.5 TCF or more. Hibernia was on stream in November 1997. Total recoverable reserves at Hibernia are estimated at 750 MMBls. Peak production of 180,000 b/d is expected by 2000-2001. Life expectancy of 20 years is predicted. The Terra Nova project, located 25 miles southeast of Hibernia, was also reviewed. It will be on stream in late 2000 with total reserves of 350-450 MMBls of oil, peak production at 115,000 to 135,000 b/d with a life expectancy of 15 years. 21 figs

    To assess residents' practice intentions since the introduction of the College of Family Physicians of Canada's Triple C curriculum, which focuses on graduating family physicians who will provide comprehensive care within traditional and newer models of family practice. A survey based on Ajzen's theory of planned behaviour was administered on 2 occasions. McMaster University in Hamilton, Ont. Residents (n = 135) who were enrolled in the Department of Family Medicine Postgraduate Residency Program at McMaster University in July 2012 and July 2013; 54 of the 60 first-year residents who completed the survey in 2012 completed it again in 2013. The survey was modeled so as to measure the respondents' intentions to practise with a comprehensive scope; determine the degree to which their attitudes, subjective norms, and perceptions of control about comprehensive practice influence those intentions; and investigate how these relationships change as residents progress through the curriculum. The survey also queried the respondents about their intentions with respect to particular medical services that underpin comprehensive practice. The responses indicate that the factors modeled by the theory of planned behaviour survey account for 60% of the variance in the residents' intentions to adopt a comprehensive scope of practice upon graduation, that there is room for curricular improvement with respect to encouraging residents to practise comprehensive care, and that targeting subjective norms about comprehensive practice might have the greatest influence on improving resident intentions. The theory of planned behaviour presents an effective approach to assessing curricular effects on resident practice intentions while also providing meaningful information for guiding further program evaluation efforts in the Department of Family Medicine at McMaster University.

  18. Ukrainian Diaspora in Canada and Its Contribution to the Establishment of Independent Ukrainian State

    Full Text Available The history kept for us names of the first Ukrainian, arrived to Canada in 1891. These are residents of the village of Nebylov in the Western Ukraine Ivan Filippov and Vasily Elenyak. The Ukrainian immigration to Canada gains mass scope only after 1896, in many respects thanks to efforts of the galitsky agronomist Osip Oleskov who sent a big flow of the Ukrainian immigrants from villages of the Western Ukraine instead of Brazil to Canada. During the first wave of the Ukrainian immigration to Canada which is considered the largest and occurred between 1891 and 1914, in the country lodged more than 170 thousand Ukrainian. The second wave of Ukrainian immigration to Canada occurred in the interwar period, especially between 1924 and 1930. The third wave of Ukrainian immigration to Canada was due to political reasons and lasted from 1947 to 1954. Many of these immigrants were political refugees, which made this wave overtly politicized. In the early 1990s began the fourth wave of Ukrainian immigration to Canada, which continues today. This wave was related mainly to economic reasons.

    "This paper is an attempt to examine the trends in union formation among various cohorts and to identify some of the socio-demographic correlates of marital timing. 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."

    2017-06-01

    Although residency training offers numerous leadership opportunities, most residents are not exposed to scripted leadership instruction. To explore one program's attitudes about leadership training, a group of otolaryngology faculty (n = 14) and residents (n = 17) was polled about their attitudes. In terms of self-perception, more faculty (10 of 14, 71.4%) than residents (9 of 17, 52.9%; P = .461) considered themselves good leaders. The majority of faculty and residents (27 of 31) thought that adults could be taught leadership ability. Given attitudes about leadership ability and the potential for improvement through instruction, consideration should be given to including such training in otolaryngology residency.

  1. Canada's isotope crisis : what next?

    International Nuclear Information System (INIS)

    Nathwani, J.; Wallace, D.

    2010-01-01

    Canada urgently requires a rigorous debate on the strategic options for ensuring a robust, reliable, and affordable supply of radioactive isotopes. Should the debate be confined to how Canada can best develop the necessary technologies solely for our own use or should Canada abandon the idea of producing its own isotope supply and any future aspirations to serve the global market? Canada's Isotope Crisis focuses on the central policy question: do we dare to try to shape the future or do we retreat into silence because we are not prepared to make the necessary investments for the future well-being of Canadians? This volume showcases pointed essays and analysis from members of the academy and individuals who have made contributions to the development of medical isotopes and pioneered their use in medical practice. It also includes commentary from those involved in the production, manufacturing, processing, and distribution of isotopes. Canada's Isotope Crisis is a multi-disciplinary effort that addresses the global dimension of isotope supply and combines expert opinions on the present and past with knowledge of the relevant government agencies and the basis for their decisions at critical junctures.

    mediated response to the presence of E. clarkei oocysts and endogenous stages was seen in 83.3% of infected adult geese, but only 20% of immature geese showed a macrophage response to the infective stages of this parasite. A massive E. clarkei infection caused the death of one goose collected at Horicon National Wildlife Refuge. Amidostomiasis, epomidiostomiasis, and renal coccidiosis were important pathogenic diseases in the Mississippi Valley Population Canada geese but did not directly cause significant mortality in the population.

  5. Summertime distribution of PAN and other reactive nitrogen species in the northern high-latitude atmosphere of eastern Canada

    1994-01-01

    Aircraft measurements of key reactive nitrogen species (NO, NO2, HNO3, PAN, PPN, NO3(-), NO(y)), C1 to C6 hydrocarbons, acetone, O3, chemical tracers (C2Cl4, CO), and important meteorological parameters were performed over eastern Canada during July to August 1990 at altitudes between 0 and 6 km as part of an Arctic Boundary Layer Expedition (ABLE3B). In the free troposphere, PAN was found to be the single most abundant reactive nitrogen species constituting a major fraction of NO(y) and was significantly more abundant than NO(x) and HNO3. PAN and O3 were well correlated both in their fine and gross structures. Compared to data previously collected in the Arctic/subarctic atmosphere over Alaska (ABLE3A), the lower troposphere (0-4 km) over eastern Canada was found to contain larger reactive nitrogen and anthropogenic tracer concentrations. At higher altitudes (4-6 km) the atmospheric composition was in many ways similar to what was seen over Alaska and supports the view that a large-scale reservoir of PAN (and NO(y)) is present in the upper troposphere over the entire Arctic/subarctic region. The reactive nitrogen budget based on missions conducted from the North Bay site (missions 2-10) showed a small shortfall, whereas the budget for data collected from the Goose Bay operation (missions 11-19) showed essential balance. It is calculated that 15-20 ppt of the observed NO(x) may find its source from the available PAN reservoir. Meteorological considerations as well as relationships between reactive nitrogen and tracer species suggest that the atmosphere over eastern Canada during summer is greatly influenced by forest fires and transported industrial pollution.

  6. Canada report on bioenergy 2009

    Canada possesses significant forest resources. This paper reviewed Canada's bioenergy potential and market. Biomass in Canada is used to produce heat and power, as well as to produce ethanol and biodiesel. Biomass is also used to produce pyrolysis oil and wood pellets. Biomass resources included woody biomass; annual residue production; hog fuel piles; forest harvest waste and urban wood residues; agricultural residues; and municipal solid wastes. Trends in biomass production and consumption were discussed, and current biomass users were identified. A review of biomass prices was presented, and imports and exports for ethanol, biodiesel, pyrolysis oil, and wood pellets were discussed. Barriers and opportunities for trade were also outlined. 6 tabs., 6 figs. 1 appendix.

    2015-03-01

    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.

    Valley-Goose Bay, Labrador. Petroleum hydrocarbon contamination at the landfill site is the result of environmentally unsound pre-1990s disposal of households and industrial solid wastes. Tree cores were taken from trembling aspen, black spruce, and white birch and analyzed by headspace......-gas chromatography-mass spectrometry. BTEX compounds were detected in tree cores, corroborating known groundwater contamination. A zone of anomalously high concentrations of total BTEX constituents was identified and recommended for monitoring by groundwater wells. Tree cores collected outside the landfill site...... at a local control area suggest the migration of contaminants off-site. Tree species exhibit different concentrations of BTEX constituents, indicating selective uptake and accumulation. Toluene in wood exhibited the highest concentrations, which may also be due to endogenous production. Meanwhile, MTBE...

    Madsen, Jesper; Williams, James Henty; Johnson, Fred A.; Tombre, Ingunn M.; Dereliev, Sergey; Kuijken, Eckhart

    2017-01-01

    An International Species Management Plan for the Svalbard population of the pink-footed goose was adopted under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds in 2012, the first case of adaptive management of a migratory waterbird population in Europe. An international working group (including statutory agencies, NGO representatives and experts) agreed on objectives and actions to maintain the population in favourable conservation status, while accounting for biodiversity, economic and recreational interests. Agreements include setting a population target to reduce agricultural conflicts and avoid tundra degradation, and using hunting in some range states to maintain stable population size. As part of the adaptive management procedures, adjustment to harvest is made annually subject to population status. This has required streamlining of monitoring and assessment activities. Three years after implementation, indicators suggest the attainment of management results. Dialogue, consensus-building and engagement among stakeholders represent the major process achievements.

    Full Text Available Smart Grids are electricity networks that use digital technology to co-ordinate the needs and capabilities of all generators, grid operators, end users and electricity market stakeholders in such a way that it can optimize asset utilization and operation while maintaining system reliability, resilience and stability. However, Smart Grids are increasingly proposing a much more distributed architecture with the integration of multiple Distributed Energy Resources (DERs that demand different control and protection schemes. In that sense, the implementation of standards such as IEC 61850 and the integration with Ethernet-based communication networks provide novel tools to manage DER efficiently. This paper analyses the potential usage and benefits of ANSI 67/67N protection in combination with Generic Object Oriented Substation Event (GOOSE communication service, from the standard 61850 of the International Electro-technical Commission (IEC, for providing adaptive network protection, specifying the configuration and implementation and exposing the obtained results.

    Full Text Available Highly pathogenic avian influenza H5N1 (HPAI H5N1 viruses can infect mammals, including humans, causing severe systemic disease with the inhibition of the immune system and a high mortality rate. In conditions of lymphoid tissue depletion, the liver plays an important role in host defence against viruses. The changes in mice liver infected with HPAI H5N1 virus A/goose/Krasnoozerskoye/627/05 have been studied. It has been shown that the virus persistence in the liver leads to the expression of proinflammatory cytokines (TNF-α, IL-6 and intracellular proteases (lysozyme, cathepsin D, and myeloperoxidase by Kupffer cells. Defective antiviral response exacerbates destructive processes in the liver accelerating the development of liver failure.

    effect of winter harshness on post-winter body condition. However, this effect was compensated along the spring migration corridor, and did not persist long enough to influence future reproduction. This highlights the importance of temporal scale when assessing impacts of environmental effects......Environmental conditions at one point of the annual cycle of migratory species may lead to cross-seasonal effects affecting fitness in subsequent seasons. Based on a long-term mark-resighting dataset and scoring of body condition in an arctic breeding goose species, we demonstrate a substantial......, and suggests a state-dependent physiological mechanism adjusting energy accumulation according to internal energy stores carried into spring. In support of these findings, the development of body condition was unaffected by whether geese used supplementary feeding sites or not. While there was no effect...

  14. Future trends in ophthalmology health human resources in Canada.

    Science.gov (United States)

    Bellan, Lorne

    2016-06-01

    Projections of future Canadian ratios of ophthalmologists to population have fluctuated because of changes in numbers of residency spots and retirement rates. Although this ratio plateaued in recent years, the ratio of ophthalmologists to the population over 65 years of age is projected to steadily deteriorate. All graduating residents are going to be needed to meet the upcoming workload, yet current graduates are finding increasing difficulty obtaining full-time positions with operating room privileges. This problem is affecting all specialties who require hospital facilities, and exploration of this problem by the Royal College, Canadian Medical Association (CMA), Resident Doctors of Canada, and council of the Provincial Deputy Ministers of Health is presented. Proposed solutions to the current job shortages include residents starting in positions outside of major metropolitan areas, clinicians in practice giving up some operating room time to make way for new graduates, government increasing infrastructure commensurate with the increased number of medical school positions, and optimizing use of current resources by running operating rooms for longer hours and on the weekends.

    1985-01-01

    The lower Flathead System Canada Goose Study was initiated to determine population trends and the effects of water level fluctuations on nest and brood habitat on the southern half of Flathead Lake and the lower Flathead River as a result of the operations of Kerr Dam. This report presents data collected during the 1984 field season as part of an ongoing project. Geese used Pablo, Kicking Horse, Ninepipe Reservoirs heavily during late summer and fall. Use of the river by geese was high during the winter, when the reservoirs were frozen, and during the breeding period. Most breeding geese left the river after broods fledged. Thirteen percent of the artificial tree nest structures on the river were used by nesting geese. Goose nest initiation on the river peaked the last week in March through the first week in April, and hatching peaked the first week in May. Predation was the most significant cause of nest loss on the river, and nest loss by flooding was not observed. Avian predation was the single largest factor contributing to nest loss on the lake. Habitat use was studied in 4 brood areas on the river and 8 brood areas on the lake, and available habitat was assessed for 2 portions of both the lake and the river. Brood habitat use was significantly different from the available habitat in all areas studied. On the lower river, broods used wheat fields, gravel bars, and shrub habitats. On the upper river, coniferous forest and shrub habitats were preferred. On the West Bay of the lake, brood areas consisted primarily of lawns and tall herbaceous habitat, while on the South Bay, marshes dominated the brood areas studied. Water levels on the river and lake affect both accessibility of these areas to brooding geese, and the ecology of the habitats preferred by geese. 43 refs., 24 figs., 31 tabs.

    Changing patterns of referral and management of hypertrophic pyloric stenosis (HPS) in North America have recently been described. Comfort with perioperative management, anesthesia, and corrective surgery have been cited as reasons for these changes. Our primary objective was to assess pyloromyotomy outcomes between different hospital types across Canada. The secondary objective was to geospatially map all pyloromyotomies to identify regions of higher HPS incidence across Canada. Data of all pyloromyotomies done between 2011 and 2013 were acquired from Canadian Institute for Health Information (CIHI). Complication rates and length of hospital stay (LOS) were analyzed. Postal codes for each patient were used to geospatially map regions of higher HPS incidence. A total of 1261 pyloromyotomies were assessed. There was no difference in LOS or complication rates between different hospital types or surgeon group. Open pyloromyotomies were done in 75% of the cases. Several regions of higher HPS incidence were identified across Canada. This study found no difference in complication rate or LOS stay between hospital type and surgeon type across Canada. This may reflect a previously identified referral trend in the United States towards pediatric centers. Several regions of higher HPS incidence were identified, and may aid in identifying genetic elements causing HPS. 2c. Crown Copyright © 2017. Published by Elsevier Inc. All rights reserved.

    International energy opportunities were reviewed, with emphasis on China, and on Canada-China Power Inc., alternatively known as 'Team Canada'. Canada-Chine Power Inc., is a company founded by three of Canada's leading engineering consulting firms, i.e., Monenco AGRA Inc., SNC Lavalin Inc., and Acres International Limited. An office was established in Beijing in January 1994. Other Canadian manufacturers and engineering companies also have been actively pursuing hydro power opportunities in China for several years in view of China's enormous demand for power. It was estimated that by the year 2000, China will install 137 GW of new capacity, and foreign investment will account for approximately a third of the growth. AGRA is working on a 5400 MW thermal plant on Hainan Island, and is in final negotiations with the Yangtze Three Gorges Development Corporation for a management information system for their 18200 MW multi-purpose project. Criteria used by AGRA to identify international opportunities include: (1) a large capital spending program in fields with capabilities, expertise and past experience, (2) access to international funding, (3) competitive Canadian technology, and (4) an acceptable business and cultural climate. In assessing the opportunities, AGRA decided to concentrate on providing technologies in greatest need, such as project management systems, computer engineering and CAD systems, and clean coal technology

  8. Improving Canada's climate change performance

    International Nuclear Information System (INIS)

    Cinq-Mars, K.

    2006-01-01

    Canada's greenhouse gas (GHG) emissions continue to increase despite ratification of the Kyoto Protocol. Combined, the growth in GH G emissions from oil and gas, electricity, heat generation, and road transportation accounted for nearly 80 per cent of the emission growth in Canada's total emissions between 1990 and 2004. Although Canada's high emission level has been attributed to economic growth and climatic and geographic constraints, this paper argued that the successful curtailment of emissions in countries similar to Canada indicates that successful emission control is an effect of conscious policy choices rather than economic and structural factors. Despite being a much smaller country, Norway has had similar levels of oil and gas production to Canada. However, Norway was one of the first countries to implement a carbon dioxide (CO 2 ) tax in 1991, from which the petroleum industry is not exempted. Norway credits the tax for the emissions-efficiency gains that have been achieved in the production of oil. In response to increased needs for electricity and heat generation, the Norwegian government has stated that new licenses for gas-fired power plants will be based on carbon capture and storage (CSS) technology. Over the 1990-20045 period, the United Kingdom (UK) saw a 26 per cent decrease in emissions from power stations despite a 24 per cent increase in electricity use. The decrease has been attributed to a shift from coal to natural gas as well as to improved catalytic emissions controls. The UK government has also created a Carbon Trust and a Low Carbon Buildings Programme. In 2001, the UK introduced the Climate Change Levy, a set of agreements with industry to promote efficiency and emissions control. A number of European countries are now starting to apply the European Union (EU) Energy Performance of Buildings Directive, which sets high standards for the energy-efficiency of new buildings. The German government attributes a drop in GHG emissions from

    International Nuclear Information System (INIS)

    Willatt, J.M.G.; Mason, A.C.

    2006-01-01

    The purpose of our study was to compare various aspects of radiology training schemes in ten countries. A questionnaire was sent to senior residents in the UK, USA, Canada, Australia, New Zealand, Italy, Egypt, India, Malaysia and Greece. The questions concerned length of training, required pre-training experience, the organization of the training scheme, teaching, resources, stages at which residents can independently perform and report examinations, fellowships, and progression to jobs. A wide variety of training, ranging from highly scheduled programs with detailed aims and objectives, to self-learning occurs across the world. Examinations and assessments are also variable. There are lessons to be learned from varying practices; more exchanges of ideas should be encouraged. In view of the ''internationalization'' of radiology services and the variation in training styles an international qualification for quality assurance purposes may be desirable. (orig.)

    International Nuclear Information System (INIS)

    1987-01-01

    The radiological surveillance program of the Department of National Health and Welfare is conducted for the purpose of determining levels of environmental radioactivity in Canada and assessing the resulting population exposures. During 1986 the program was strongly influenced by radioactive fallout on Canada resulting from the Chernobyl nuclear reactor accident on April 26, 1986 in the Soviet Ukraine. The Environmental Radiation Hazards Division (ERHD) increased its frequency of analyses of environmental samples immediately following the accident. Interim screening limits for foodstuffs were developed. A measurement program for radioactivity in domestic and imported foods was implemented. The ERHD measurement program was supplemented by additional measurements conducted by many other private and government laboratories. Radiation doses to Canadian from Chernobyl fallout were extremely low with no group in the population receiving more than 10 microsieverts

    Although the topic of language maintenance has received considerable attention from linguists around the world, there are still many aspects of this language-contact phenomenon that could be examined further. This paper aims to contribute to the existing body of knowledge by exploring the state of Croatian as a heritage language in Canada. The aim of the paper is two-fold. The first is to describe the demographic characteristics of the Croatian community by investigating the number of people ...

  15. Canada: The largest uranium producer

    1985-01-01

    Despite all the current difficulties, previous erroneous forecasts and other mistakes, the longer term future looks good for uranium mining and for Canada's industry in particular. Saskatchewan continues to offer the most exciting new prospects, the huge and fabulously high grade Cigar Lake deposits being the most spectacular of the recent discoveries. Notwithstanding continuous mining for 30 years from Elliot Lake there still remain there significant uncommitted reserves which can be developed when the market for uranium is in better balance

  16. The nuclear debate in Canada

    1981-06-01

    The author argues that the nuclear debate in Canada is concerned less with the safety of nuclear power plants and more with arguments of economics and social decision-making. The nuclear industry cannot afford to neglect the continuing need to inform the public about nuclear risks. But there is also a need to develop specific arguments to increase public acceptance of nuclear energy as an economic, democratic and equitable energy option

  17. Indian Reserves: Canada's Developing Nations

    OpenAIRE

    Musto, Richard J.

    1990-01-01

    Indian reserves are the most visible reminder of the separation of aboriginal people from the rest of Canada and other Canadians. Illness patterns and social conditions in Native communities closely parallel those in developing nations. While they continue to have a large burden of infectious diseases, these groups also have an increased incidence of chronic and lifestyle diseases as well as environment-related conditions. Similarities can be seen in urban areas between immigrants from abroad...

    Mayans, David; Schneider, Logan; Adams, Nellie; Khawaja, Ayaz M.; Engstrom, John

    2016-01-01

    Objective: To survey US-trained graduating neurology residents who are American Academy of Neurology members, in an effort to trend perceived quality and completeness of graduate neurology education. Methods: An electronic survey was sent to all American Academy of Neurology members graduating from US neurology residency programs in the Spring of 2014. Results: Of 805 eligible respondents, 24% completed the survey. Ninety-three percent of adult neurology residents and 56% of child neurology residents reported plans to pursue fellowship training after residency. Respondents reported a desire for additional training in neurocritical care, neuro-oncology, neuromuscular diseases, botulinum toxin injection, and nerve blocks. There remains a clear deficit in business training of neurology residents, although there was notable improvement in knowledge of coding and office management compared to previous surveys. Discussion: Although there are still areas of perceived weakness in neurology training, graduating neurology residents feel generally well prepared for their chosen careers. However, most still pursue fellowship training for reasons that are little understood. In addition to certain subspecialties and procedures, practice management remains deficient in neurology training and is a point of future insecurity for most residents. Future curriculum changes should consider resident-reported gaps in knowledge, with careful consideration of improving business training. PMID:26976522

  1. The effect of limiting residents' work hours on their surgical training: a Canadian perspective.

    Science.gov (United States)

    Romanchuk, Ken

    2004-05-01

    Restrictions in residents' work hours have been in place in Canada for roughly a decade, having been negotiated rather than imposed. The changes in residents' schedules that resulted are roughly equivalent to the limitation of 80 duty hours per week in the United States. When work-hours restrictions began, surgery faculty were worried that residents' experience would be compromised. But these fears have not materialized. Why? The author maintains there are many reasons. (1) Most surgical procedures are now faster, and lengthy inpatient care has diminished, all of which saves time. (2) Formerly difficult or risky procedures are now performed more frequently and safely, which increases residents' education about difficult conditions. (3) A variety of resources (e.g., skills-transfer courses, surgical simulators, etc.) are now available for residents to learn and evolve surgical techniques, and residents take advantage of these resources, being highly motivated to learn the best in the time available to them. (4) There have been positive changes in residents' education that have helped them become more efficient learners than before, with improved resources and skills for faster access to information. The author maintains that in his present surgery residency program, the residents still work extremely hard but are more protected from the unending demands for patient care. They have more time for orderly study and greater opportunities to develop skills other than technical ones. They are in a happier work setting, which the author strongly believes facilitates improved patient care.

  2. Women in Physics in Canada

    Science.gov (United States)

    McKenna, Janis

    2012-10-01

    Here we are in the 21st century in Canada, where most of us would say that young girls and boys have equal access to education, opportunities, and careers of their own choice. In Canada, women currently outnumber men in full-time university enrollment, in Medical Schools and in Law Schools. 48% of the Canadian work force is female, yet women make up only 21% of working professionals in science, engineering and technology. Canada-wide in Physics, the situation is such that only 20% of our BSc graduates are women, and 19% of our PhD graduates are women. It is evident that the ``leaky pipeline'' in Physics leaks most at a young age, before BSc graduation. High school physics statistics in BC indicate that while most of the grade 12 science and math disciplines have roughly equal numbers of young men and women enrolled, this is not the case for high school physics, where province-wide, only 30% of Physics 12 students are women. (Biology is also skewed, but in the other direction: 62% of Biology 12 students are women) This poster will present current statistics and will hopefully be a wake-up call for us all to consider participating in more outreach in science, and especially physics, in our high schools.

  3. Colorectal cancer screening in Canada

    Energy Technology Data Exchange (ETDEWEB)

    2001-02-01

    Colorectal carcinoma (CRC) is an important cause of morbidity and mortality in Canada, ranking third among all cancers. In 1998, there were 16,500 new cases and 6300 deaths from this disease. Predictions for 2000 were similar. There has been a gradual decrease in age-adjusted incidence and mortality from CRC over the last few years, but the actual number of cases is expected to increase significantly over the next decade because of changing age demographics. The regional incidence is lowest on the west coast and highest on the east coast, with Ontario and Quebec in between. In Canada, the lifetime risk of dying from CRC is 2.8%, compared with 8.1% for lung cancer in men, 4.5% for lung cancer in women, 3.6% for prostate cancer in men and 3.9% for breast cancer in women. CRC is a disease of developed, rather than developing countries, and the incidence in Canada is among the highest in the world, and higher in relative terms than in the United States. Primary prevention, including diet modification and other lifestyle influences, may have the most significant long-term effects on the problem, but earlier detection and treatment would seem to be the most advantageous medium-term objectives. An excellent review and guidelines article by Winawer and colleagues has formed the basis for an informed discussion on CRC and screening-related issues. (author)

  4. Indigenous Educational Attainment in Canada

    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.

  5. Overview of Canada's uranium industry

    International Nuclear Information System (INIS)

    Lowell, A.F.

    1982-06-01

    This paper places Canada's uranium industry in its international context. Most uranium, except that produced in the United States, is traded internationally. A brief history of the industry worldwide is given to show how the principal producing areas have fared to date. The industry is young, highly cyclical, and still far from achieving stability. Uranium is a single end-use commodity, entirely dependent on the generation of electricity in nuclear stations, and is without price elasticity: lowering the price does not increase demand. The typical nuclear fuel processing chain has not encouraged or led to much vertical integration. Uranium is subject to more governmental control than any other commodity. The principal market is located in the industrial countries of western Europe, the United States, Canada, and the far east. The uranium supply-demand situation is reviewed, including the current and near-term oversupply and the longer term outlook to 1995. The major negative impact of reactor cancellations and deferments in the United States is discussed. Because of the difficulty in getting reactors on line, it has become easier to forecast the demand for uranium over the next 10 years. It is more difficult to predict how that demand will be met from the more than ample competing sources. Canada's potential for supplying a significant portion of this demand is considered in relation to producers and potential new producers in other countries

  6. Golden Years or Retirement Fears? Private Pension Inequality Among Canada's Immigrants.

    Curtis, Josh; Lightman, Naomi

    2017-06-01

    Currently, many immigrants are disqualified from Canada's public pension scheme because of residency requirements. In addition, decades of low income and labour market exclusion prohibit many Canadian immigrants from building adequate private pension savings throughout their working life. Together, these factors present serious concerns for immigrant seniors' economic well-being. Using Canadian census data spanning a twenty-year period (1991-2011), we find that income from personal savings plans and investments has declined sharply for both native-born and immigrant Canadians, with recent immigrant cohorts faring worst. However, since 1991, native-born and immigrant men living in Canada for 40-plus years had major gains in private employer pensions (Registered Pension Plans; [RPPs]). Yet RPP income for all other immigrant cohorts remained stable or declined during these decades. Thus, the data demonstrate a worrisome growing private savings gap between native-born men and all others in Canada, with newer immigrants and women faring worst.

    The decision by prosthodontic residency program directors to employ the Match process highlights the need to understand applicant priorities that influence their choice of which programs to rank highly. The purpose of this study is to determine the factors that were most important to residents when choosing from among nonmilitary based prosthodontics dental residency programs in the United States. Following completion of a pilot study, all currently enrolled prosthodontic residents at nonmilitary residency programs were invited to participate via the internet. The study consisted of a survey instrument asking residents to rank 26 possible factors that might impact an applicant's choice of residency program. In addition, the instrument collected other possible influencing variables including gender and debt load. Mean rank scores were compared to determine the most and least important factors. Kruskal-Wallis test was used to compare specific factors between the possible influencing variables. Two hundred and thirty residents completed the survey instrument, representing a 54.1% response rate of possible participants. With regard to factors influencing program choice, reputation of the residency program was the factor ranked the highest by participants, followed in descending order by the program director's personality, curriculum content, access to use of the latest digital technology, and opportunities for dental implant placement. Quality of schools for children, community outreach opportunities, and the ability to moonlight were ranked as the least important factors. Male and female residents ranked factors such as tuition/stipend, curriculum content, and community outreach opportunities significantly differently. Depending on debt load, residents ranked the factors tuition/stipend, ability to moonlight, curriculum content, and safety of the area where the program is differently. Current prosthodontic residents valued the reputation of the program as the most

    Context: Recognition of the importance of informatics to the practice of pathology has surged. Training residents in pathology informatics has been a daunting task for most residency programs in the United States because faculty often lacks experience and training resources. Nevertheless, developing resident competence in informatics is essential for the future of pathology as a specialty. Objective: To develop and deliver a pathology informatics curriculum and instructional framework that guides pathology residency programs in training residents in critical pathology informatics knowledge and skills, and meets Accreditation Council for Graduate Medical Education Informatics Milestones. Design: The College of American Pathologists, Association of Pathology Chairs, and Association for Pathology Informatics formed a partnership and expert work group to identify critical pathology informatics training outcomes and to create a highly adaptable curriculum and instructional approach, supported by a multiyear change management strategy. Results: Pathology Informatics Essentials for Residents (PIER) is a rigorous approach for educating all pathology residents in important pathology informatics knowledge and skills. PIER includes an instructional resource guide and toolkit for incorporating informatics training into residency programs that vary in needs, size, settings, and resources. PIER is available at http://www.apcprods.org/PIER (accessed April 6, 2016). Conclusions: PIER is an important contribution to informatics training in pathology residency programs. PIER introduces pathology trainees to broadly useful informatics concepts and tools that are relevant to practice. PIER provides residency program directors with a means to implement a standardized informatics training curriculum, to adapt the approach to local program needs, and to evaluate resident performance and progress over time.

    2013-01-01

    Programmatic changes for the dermatology residency program at The University of Texas Medical Branch were first introduced in 2005, with the faculty goal incorporating formal dermatology research projects into the 3-year postgraduate training period. This curriculum initially developed as a recommendation for voluntary scholarly project activity by residents, but it evolved into a program requirement for all residents in 2009. Departmental support for this activity includes assignment of a faculty mentor with similar interest about the research topic, financial support from the department for needed supplies, materials, and statistical consultation with the Office of Biostatistics for study design and data analysis, a 2-week elective that provides protected time from clinical activities for the purpose of preparing research for publication and submission to a peer-reviewed medical journal, and a departmental award in recognition for the best resident scholarly project each year. Since the inception of this program, five classes have graduated a total of 16 residents. Ten residents submitted their research studies for peer review and published their scholarly projects in seven dermatology journals through the current academic year. These articles included three prospective investigations, three surveys, one article related to dermatology education, one retrospective chart review, one case series, and one article about dermatopathology. An additional article from a 2012 graduate about dermatology education has also been submitted to a journal. This new program for residents was adapted from our historically successful Dermatology Honors Research Program for medical students at The University of Texas Medical Branch. Our experience with this academic initiative to promote dermatology research by residents is outlined. It is recommended that additional residency programs should consider adopting similar research programs to enrich resident education. PMID:23901305

    The EarthScope Transportable Array is deploying about 260 stations in Alaska and western Canada. IRIS and EarthScope are partnering with the Alaska Earthquake Center, part of the University of Alaska's Geophysical Institute, and Yukon College to spread awareness of earthquakes in Alaska and western Canada and the benefits of the Transportable Array for people living in these regions. We provide an update of ongoing education and outreach activities in Alaska and Canada as well as continued efforts to publicize the Transportable Array in the Lower 48. Nearly all parts of Alaska and portions of western Canada are tectonically active. The tectonic and seismic variability of Alaska, in particular, requires focused attention at the regional level, and the remoteness and inaccessibility of most Alaskan and western Canadian villages and towns often makes frequent visits difficult. When a community is accessible, every opportunity to engage the residents is made. Booths at state fairs and large cultural gatherings, such as the annual convention of the Alaska Federation of Natives, are excellent venues to distribute earthquake information and to demonstrate a wide variety of educational products and web-based applications related to seismology and the Transportable Array that residents can use in their own communities. Meetings and interviews with Alaska Native Elders and tribal councils discussing past earthquakes has led to a better understanding of how Alaskans view and understand earthquakes. Region-specific publications have been developed to tie in a sense of place for residents of Alaska and the Yukon. The Alaska content for IRIS's Active Earth Monitor emphasizes the widespread tectonic and seismic features and offers not just Alaska residents, but anyone interested in Alaska, a glimpse into what is going on beneath their feet. The concerted efforts of the outreach team will have lasting effects on Alaskan and Canadian understanding of the seismic hazard and

    -Immigrants from ethnic minority groups represent an increasing proportion of the population in many high-income countries but little is known about the causes and amount of variation between various immigrant groups in the incidence of major cardiovascular events. -We conducted the Cardiovascular Health in Ambulatory Care Research Team (CANHEART) Immigrant study, a big data initiative, linking information from Citizenship and Immigration Canada's Permanent Resident database to nine population-based health databases. A cohort of 824 662 first-generation immigrants aged 30 to 74 as of January 2002 from eight major ethnic groups and 201 countries of birth who immigrated to Ontario, Canada between 1985 and 2000 were compared to a reference group of 5.2 million long-term residents. The overall 10-year age-standardized incidence of major cardiovascular events was 30% lower among immigrants compared with long-term residents. East Asian immigrants (predominantly ethnic Chinese) had the lowest incidence overall (2.4 in males, 1.1 in females per 1000 person-years) but this increased with greater duration of stay in Canada. South Asian immigrants, including those born in Guyana had the highest event rates (8.9 in males, 3.6 in females per 1000 person-years), along with immigrants born in Iraq and Afghanistan. Adjustment for traditional risk factors reduced but did not eliminate differences in cardiovascular risk between various ethnic groups and long-term residents. -Striking differences in the incidence of cardiovascular events exist among immigrants to Canada from different ethnic backgrounds. Traditional risk factors explain part but not all of these differences.

    The extent to which species are plastic in the timing of their reproductive events relative to phenology suggests how change might affect their demography. An ecological mismatch between the timing of hatch for avian species and the peak availability in quality and quantity of forage for rapidly growing offspring might ultimately affect recruitment to the breeding population unless individuals can adjust the timing of breeding to adapt to changing phenology. We evaluated effects of goose density, hatch timing relative to forage plant phenology, and weather indices on annual growth of pre-fledging Canada geese (Branta canadensis) from 1993-2010 at Akimiski Island, Nunavut. We found effects of both density and hatch timing relative to forage plant phenology; the earlier that eggs hatched relative to forage plant phenology, the larger the mean gosling size near fledging. Goslings were smallest in years when hatch was latest relative to forage plant phenology, and when local abundance of breeding adults was highest. We found no evidence for a trend in relative hatch timing, but it was apparent that in early springs, Canada geese tended to hatch later relative to vegetation phenology, suggesting that geese were not always able to adjust the timing of nesting as rapidly as vegetation phenology was advanced. Analyses using forage biomass information revealed a positive relationship between gosling size and per capita biomass availability, suggesting a causal mechanism for the density effect. The effects of weather parameters explained additional variation in mean annual gosling size, although total June and July rainfall had a small additive effect on gosling size. Modelling of annual first year survival probability using mean annual gosling size as an annual covariate revealed a positive relationship, suggesting that reduced gosling growth negatively impacts recruitment.

    2016-01-01

    The practice patterns of Obstetricians and Gynaecologists continue to evolve with each new generation of physicians. Diversifying subspecialties, changes in resident duty hours, job market saturation, and desire for work-life balance are playing stronger roles. Professional practice direction and needs assessment may be aided by awareness of future Obstetrics and Gynaecology physician career plans and expectations. The objective of this study was to determine the expected career plans and practice patterns of Canadian Obstetrics and Gynaecology residents following residency. The SOGC Junior Member Committee administered its third career planning survey to Canadian Obstetrics and Gynaecology residents electronically in December 2011. The data collected was statistically analyzed and compared to previous surveys. There were 183 responses giving a response rate of 43%. More than one half of all residents were considering postgraduate training (58%). Projected practice patterns included: 84% maintaining obstetrical practice, 60% locuming, and 50% job-sharing. The majority of residents expected to work in a 6 to 10 person call group (48%), work 3 to 5 call shifts per month (72%), work 41 to 60 hours weekly (69%), and practise in a city with a population greater than 500 000 (45%). Only 18% of residents surveyed were in favour of streaming residency programs in Obstetrics and Gynaecology. Canadian resident career plan and expected practice pattern assessment remains an important tool for aiding in resource allocation and strategic development of care and training in Obstetrics and Gynaecology in Canada.

    The purpose of the present survey was to (1) establish the prevalence of Crew Resource Management (CRM)- and team-training interventions among general surgery residency programs of the United States and Canada; (2) to characterize current approaches to training and assessment of nontechnical skills; and (3) to inquire about program directors' (PDs') recommendations for future curricula in graduate medical education. An online questionnaire was developed by the authors and distributed via email to the directors of all accredited general surgery residency programs across the United States and Canada. After 3 email reminders, paper versions were sent to all nonresponders. PDs of accredited general surgery residency programs in the United States and Canada. One hundred twenty (47%) PDs from the United States and 9 (53%) from Canada responded to the survey. Of all respondents, 32% (n = 40) indicated conducting designated team-training interventions for residents. Three main instructional strategies were identified: combined approaches using simulation and didactic methods (42%, n = 16); predominantly simulation-based approaches (37%, n = 14); and didactic approaches (21%, n = 8). Correspondingly, 83% (n = 93) of respondents recommended a combination of didactic methods and opportunities for practice for future curricula. A high agreement between responding PDs was shown regarding learning objectives for a proposed team-based training curriculum (α = 0.95). The self-reported prevalence of designated CRM- and team-training interventions among responding surgical residency programs was low. For the design of future curricula, the vast majority of responding PDs advocated for the combination of interactive didactic methods and opportunities for practice.

This prospective observational cohort study was set in a large Canadian family medicine residency program. Intervention was the California Critical Thinking Skills Test (CCTST), administered at three points in residency: upon entry, at mid-point, and at graduation. Results from the CCTST, Canadian Residency Matching Service file, and interview scores were compared to other measures of academic performance (Medical Colleges Admission Test [MCAT] and College of Family Physicians of Canada [CCFP] certification examination results). For participants (n=60), significant positive correlations were found between critical thinking skills and performance on tests of knowledge. For the MCAT, CCTST scores correlated positively with full scores (n=24, r=0.57) as well as with each section score (verbal reasoning: r=0.59; physical sciences: r=0.64; biological sciences: r=0.54). For CCFP examination, CCTST correlated reliably with both sections (n=49, orals: r=0.34; short answer: r=0.47). Additionally, CCTST was a better predictor of performance on the CCFP exam than was the interview score at selection into the residency program (Fisher's r-to-z test, z=2.25). Success on a critical thinking skills exam was found to predict success on family medicine certification examinations. Given that critical thinking skills appear to be stable throughout residency training, including an assessment of critical thinking in the selection process may help identify applicants more likely to be successful on final certification exam.

    Social pediatrics teaches pediatric residents how to understand disease within their patients' social, environmental and political contexts. It's an essential component of pediatric residency training; however there is very little literature that addresses how such a broad-ranging topic can be taught effectively. The aim of this study was to determine and characterize social pediatric education in our pediatric residency training in order to identify strengths and gaps. A social pediatrics curriculum map was developed, attending to 3 different dimensions: (1) the intended curriculum as prescribed by the Objectives of Training for Pediatrics of the Royal College of Physicians and Surgeons of Canada (RCPSC), (2) the formal curriculum defined by rotation-specific learning objectives, and (3) the informal/hidden curriculum as reflected in resident and teacher experiences and perceptions. Forty-one social pediatric learning objectives were extracted from the RCPSC Objectives of Training for Pediatrics, most were listed in the Medical Expert (51%) and Health Advocate competencies (24%). Almost all RCPSC social pediatric learning objectives were identified in more than one rotation and/or seminar. Adolescent Medicine (29.2%), Pediatric Ambulatory Medicine (26.2%) and Developmental Pediatrics (25%) listed the highest proportion of social pediatric learning objectives. Four (10%) RCPSC social pediatric objectives were not explicitly named within learning objectives of the formal curriculum. The informal curriculum revealed that both teachers and residents viewed social pediatrics as integral to all clinical encounters. Perceived barriers to teaching and learning of social pediatrics included time constraints, particularly in a tertiary care environment, and the value of social pediatrics relative to medical expert knowledge. Despite the lack of an explicit thematic presentation of social pediatric learning objectives by the Royal College and residency training program

    Visa trainees are international medical graduates (IMG) who come to Canada to train in a post-graduate medical education (PGME) program under a student or employment visa and are expected to return to their country of origin after training. We examined the credentialing and retention of visa trainees who entered PGME programs between 2005 and 2011. Using the Canadian Post-MD Education Registry's National IMG Database linked to Scott's Medical Database, we examined four outcomes: (1) passing the Medical Council of Canada Qualifying Examination Part 2 (MCCQE2), (2) obtaining a specialty designation (CCFP, FRCPC/SC), and (3) working in Canada after training and (4) in 2015. The National IMG Database is the most comprehensive source of information on IMG in Canada; data were provided by physician training and credentialing organizations. Scott's Medical Database provides data on physician locations in Canada. There were 233 visa trainees in the study; 39.5% passed the MCCQE2, 45.9% obtained a specialty designation, 24.0% worked in Canada after their training, and 53.6% worked in Canada in 2015. Family medicine trainees (OR = 8.33; 95% CI = 1.69-33.33) and residents (OR = 3.45; 95% CI = 1.96-6.25) were more likely than other specialist and fellow trainees, respectively, to pass the MCCQE2. Residents (OR = 7.69; 95% CI = 4.35-14.29) were more likely to obtain a specialty credential than fellows. Visa trainees eligible for a full license were more likely than those not eligible for a full license to work in Canada following training (OR = 3.41; 95% CI = 1.80-6.43) and in 2015 (OR = 3.34; 95% CI = 1.78-6.27). Visa training programs represent another route for IMG to qualify for and enter the physician workforce in Canada. The growth in the number of visa trainees and the high retention of these physicians warrant further consideration of the oversight and coordination of visa trainee programs in provincial and in pan

    2014-01-01

    The revised ABR board certification process has updated the method by which diagnostic radiology residents are evaluated for competency in clinical radiologic physics. In this work, the author reports the successful design and implementation of a resident-taught physics course consisting of 5 weekly, hour-long lectures intended for incoming first-year radiology residents in their first month of training. To the author's knowledge, this is the first description of a course designed to provide a very early framework for ongoing physics education throughout residency without increasing the didactic burden on faculty members. Twenty-six first-year residents spanning 2 academic years took the course and reported subjective improvement in their knowledge (90%) and interest (75%) in imaging physics and a high level of satisfaction with the use of senior residents as physics educators. Based on the success of this course and the minimal resources required for implementation, this work may serve as a blueprint for other radiology residency programs seeking to develop revised physics curricula.

    Residents must develop a diverse range of skills in order to practice neurosurgery safely and effectively. The purpose of this study was to identify the foundational skills required for neurosurgical trainees as they transition from medical school to residency. Based on the CanMEDS competency framework, a web-based survey was distributed to all Canadian academic neurosurgical centers, targeting incoming and current PGY-1 neurosurgical residents as well as program directors. Using Likert scale and free-text responses, respondents rated the importance of various cognitive (e.g. management of raised intracranial pressure), technical (e.g. performing a lumbar puncture) and behavioral skills (e.g. obtaining informed consent) required for a PGY-1 neurosurgical resident. Of 52 individuals contacted, 38 responses were received. Of these, 10 were from program directors (71%), 11 from current PGY-1 residents (58%) and 17 from incoming PGY-1 residents (89%). Respondents emphasized operative skills such as proper sterile technique and patient positioning; clinical skills such as lesion localization and interpreting neuro-imaging; management skills for common scenarios such as raised intracranial pressure and status epilepticus; and technical skills such as lumbar puncture and external ventricular drain placement. Free text answers were concordant with the Likert scale results. We surveyed Canadian neurosurgical program directors and PGY-1 residents to identify areas perceived as foundational to neurosurgical residency education and training. This information is valuable for evaluating the appropriateness of a training program's goals and objectives, as well as for generating a national educational curriculum for incoming PGY-1 residents.

    Full Text Available Abstract Background The CanMEDS Health Advocate role, one of seven roles mandated by the Royal College of Physicians and Surgeons Canada, pertains to a physician's responsibility to use their expertise and influence to advance the wellbeing of patients, communities, and populations. We conducted our study to examine resident attitudes and self-reported competencies related to health advocacy, due to limited information in the literature on this topic. Methods We conducted a pilot experience with seven internal medicine residents participating in a community health promotion event. The residents provided narrative feedback after the event and the information was used to generate items for a health advocacy survey. Face validity was established by having the same residents review the survey. Content validity was established by inviting an expert physician panel to review the survey. The refined survey was then distributed to a cohort of core Internal Medicine residents electronically after attendance at an academic retreat teaching residents about advocacy through didactic sessions. Results The survey was completed by 76 residents with a response rate of 68%. The majority agreed to accept an advocacy role for societal health needs beyond caring for individual patients. Most confirmed their ability to identify health determinants and reaffirmed the inherent requirements for health advocacy. While involvement in health advocacy was common during high school and undergraduate studies, 76% of residents reported no current engagement in advocacy activity, and 36% were undecided if they would engage in advocacy during their remaining time as residents, fellows or staff. The common barriers reported were insufficient time, rest and stress. Conclusions Medical residents endorsed the role of health advocate and reported proficiency in determining the medical and bio-psychosocial determinants of individuals and communities. Few residents, however, were

    1996-02-01

    A series of definitions of tools and processes for developing a national strategy to select and designate areas for protection and preservation in their natural state in Canada, were presented. Through a series of on-site visits, and the advice and experience of hundreds of Canadians, a common vision of protected areas across the country and clear principles for planning were developed. Partnerships and collaboration between governments, native peoples and non-governmental groups were the guiding principles of the Committee`s deliberations. Ecological factors were said to have been fully considered before any of the decisions were made. Aboriginal peoples` rights to continue their traditional use of the land were taken into account and supported. Twenty recommendations that were both practical and practicable were made that would enhance the rate of progress and enable Canada to complete the network of protected areas by the year 2000, in line with national and international commitments. Effective communication by all interested parties, commitment to action by the highest levels of government with appropriate infrastructure and resources, flexibility and innovation in the use of resources, and agreed-upon priorities were cited as the keys to success.

    Recruitment drive for nurse gradutates British Columbia (BC), the westernmost Canadian province, urgently needs 1,500 qualified nurses graduates to staff longterm care and assisted-living beds as well as home care clients. The provincial government has launched a $160,000 (£78,600) marketing campaign called BC Cares. Craig Hebert, dean of development and access training at Northern Lights College in BC, said: 'The industry needs to get the message out to students that there has never been a better time to start a career in senior health care. Graduates who study for about one year, sometimes less, will have their pick of jobs in a number of service environments and can advance relatively quickly to the nursing profession.'

    2012-03-01

    Sharing resources through distance education has been proposed as 1 way to deal with a lack of full-time faculty in orthodontic residency programs. To keep distance education for orthodontic residents as cost-effective as possible while retaining interaction, we developed a "blended" interactive distance learning approach that combines observation of Web-based seminars with live postseminar discussions. For the 2009-2010 academic year, a grant from the American Association of Orthodontists opened access to the blended learning experience to all orthodontic programs in the United States and Canada. The specific aims of this project were to (1) measure programmatic interest in using blended distance learning, (2) determine resident and faculty interest, (3) determine the seminars' perceived usefulness, and (4) elicit feedback regarding future use. Participants in this project were expected to (1) read all assigned articles before viewing a recorded seminar, (2) watch a 1 to 1.5 hour recording of an actual interactive seminar on a Web site, and (3) participate in a 30-minute follow-up discussion immediately after watching the recorded seminar either with a faculty member at the participating institution or via a videoconference with the leader of the Web-based seminar. The residents and faculty then completed surveys about the experience. Half (52%) of the 63 orthodontic programs in the United States fully participated in this project. The blended approach to distance learning was judged to be effective and enjoyable; faculty members were somewhat more enthusiastic about the experience than were residents. Most residents were not adequately prepared for the seminars (only 14% read all preparatory articles in depth); this impacted their perception of the effectiveness and enjoyability of the experience (P = 0.0016). Prepared residents reported a greater ability to learn from the seminars (P = 0.0035) than those who did not read, and also indicated that they were more

  10. Landfill gas management in Canada

    International Nuclear Information System (INIS)

    David, A.

    1997-01-01

    Landfill gas produced from solid waste landfills is one of the most significant sources of anthropogenic methane in Canada. Methane, a potent greenhouse gas, is 24.5 times more powerful than carbon dioxide by weight in terms of global climate change. Landfill gas recovery plays an important role in Canada's commitment to stabilize greenhouse gas emissions at 1990 levels by the year 2000 under the United Nations Framework Convention on Climate Change. Landfill gas is a potentially harmful emission that can be converted into a reliable environmentally-sustainable energy source used to generate electricity, fuel industries and heat buildings. The recovery and utilization of landfill gas is a win-win situation which makes good sense from local, regional and global perspectives. It provides the benefits of (1) reducing the release of greenhouse gases that contribute to global warming; (2) limiting odors; (3) controlling damage to vegetation; (4) reducing risks from explosions, fires and asphyxiation; (5) converting a harmful emission into a reliable energy source; and (6) creating a potential source of revenue and profit. Canadian landfills generate about 1 million tons of methane every year; the equivalent energy of 9 million barrels of oil (eight oil super tankers), or enough energy to meet the annual heating needs of more than half a million Canadian homes. Currently, twenty-seven facilities recover and combust roughly 25% of the methane generated by Canadian landfills producing about 3.2 PJ (10 15 Joules) of energy including 80 MW of electricity and direct fuel for nearby facilities (e.g., cement plants, gypsum board manufacturers, recycling facilities, greenhouses). This paper reviews landfill gas characteristics; environmental, health and safety impacts; landfill gas management in Canada; the costs of landfill gas recovery and utilization systems; and on-going projects on landfill gas utilization and flaring

    Resident duty hours have recently been under criticism, with concerns for resident and patient well-being. Historically, call shifts have been long, and some residency training programs have now restricted shift lengths. Data and opinions about the effects of such restrictions are conflicting. The Internal Medicine Residency Program at Dalhousie University recently moved from a traditional call structure to a day float/night float system. This study evaluated how this change in duty hours affected resident perceptions in several key domains. Senior residents from an internal medicine training program in Canada responded to an anonymous online survey immediately before and 6 months after the implementation of duty hour reform. The survey contained questions relating to three major domains: resident wellness, ability to deliver quality health care, and medical education experience. Mean pre- and post-intervention scores were compared using the t-test for paired samples. Twenty-three of 27 (85 %) senior residents completed both pre- and post-reform surveys. Residents perceived significant changes in many domains with duty hour reform. These included improved general wellness, less exposure to personal harm, fewer feelings of isolation, less potential for error, improvement in clinical skills expertise, increased work efficiency, more successful teaching, increased proficiency in medical skills, more successful learning, and fewer rotation disruptions. Senior residents in a Canadian internal medicine training program perceived significant benefits in medical education experience, ability to deliver healthcare, and resident wellness after implementation of duty hour reform.

  18. An Energy Strategy for Canada

    Directory of Open Access Journals (Sweden)

    Michal C. Moore

    2015-10-01

    Full Text Available Canada is struggling to fully develop, sell and move its energy resources. This is a dramatic change from the recent past where the U.S. has provided stable growth in demand for energy supplied by the provinces, from hydrocarbons to electricity. Current circumstances now challenge this relationship, adding environmental, policy and economic hurdles that exacerbate the impact of fluctuations in world demand and pricing. In addition, competitive interaction between provinces, aboriginal land owners and special interest groups complicate and compound the issues of royalty returns, regulatory authority and direction, land-use management and long-term market opportunities for Canadian companies. There is no strategic document guiding the country’s energy future. As the steward of one of the largest, most diverse and valuable energy "banks" in the world, Canada has a unique opportunity to exploit a critical and valuable economic niche in the world economy. Given the lack of federal leadership and the tendency for each province to undercut each other in the same marketplace, there is also the distinct possibility the nation will squander the opportunity. This document offers the rationale for a comprehensive energy strategy, literally a vision where Canada can lead and not follow opportunities in energy markets. This strategic approach to energy systems by definition will include transportation, housing, employment and financial markets. It is not a plan, not a foil for tax or policy guidance in one or more sectors. This strategy is a fundamental rail on which plans, tactics and policies can be built. This vision identifies how the provinces can work together using all the tools available to them, maximizing long-term resource development while minimizing environmental damage. This document assumes there can be a broad commitment and effort by the federal government to help build those tools, providing guidance and assistance where needed without

    The structure of capital costs during NPP construction in Canada is considered. Capital costs comprise direct costs (cost of the ground and ground rights, infrastructure, reactor equipment, turbogenerators, electrotechnical equipment, auxiliary equipment), indirect costs (construction equipment and services, engineering works and management services, insurance payments, freight, training, operating expenditures), capital per cents for the period of construction and cost of heavy water storages. It proceeds from the analysis of the construction cost structure for a NPP with the CANDU reactor of unit power of 515, 740 and 880 MW, that direct costs make up on the average 62%

    All wells drilled in Western Canada during the first nine months of 1999 are listed and sorted into 12 geographical areas used in the Petroleum Services Association of Canada (PSAC) well cost study. Each area represents wells of common drilling, production and depth characteristics. Area totals for well counts and meters drilled were determined from the sorting process. Previous years' activities are reviewed and various operators and PSAC members contacted to review upcoming programs. In addition, trends and other projections were consulted to develop an estimate of drilling activity for the rest of 1999 as well as a projection of drilling activity for 2000. The historical and projected drilling activities were tabulated and plotted for each area. Average drilling costs for each area were determined, and the total expenditures were calculated for each area by multiplying the the projected meterage by the adjusted drilling costs. All costs were allocated to various services and products utilizing percentages determined in the Well Cost Study. During the sorting process, a list was developed of the major operators in each area, which list is included in the report along with average depths and types of wells drilled by the various operators in each area. The costs included in the report include only drilling and completion operations, starting with the building of the location prior to drilling, and ending with the installation of the wellhead after construction. 5 tabs

  3. Nuclear emergency preparedness in Canada

    International Nuclear Information System (INIS)

    1993-03-01

    The preparedness of utilities and government agencies at various levels for dealing with nuclear emergencies occurring at nuclear reactors in Canada is reviewed and assessed. The review is centered on power reactors, but selected research reactors are included also. Emergency planning in the U.S.A., Germany and France, and international recommendations on emergency planning are reviewed to provide background and a basis for comparison. The findings are that Canadians are generally well protected by existing nuclear emergency plans at the electric utility and provincial levels but there are improvements that can be made, mainly at the federal level and in federal-provincial coordination. Ten issues of importance are identified: commitment to nuclear emergency planning by the federal government; division of federal and provincial roles and responsibilities; auditing of nuclear emergency preparedness of all levels of government and of electric utilities; the availability of technical guidance appropriate to Canada; protective action levels for public health and safety; communication with the public; planning and response for the later phases of a nuclear emergency; off-site exercises and training; coordination of international assistance; and emergency planning for research reactors.

    Historical relationships between weather, the Canadian fire weather index (FWI) system components and area burned in Canadian ecozones were analysed on a monthly basis in tandem with output from the Canadian and the Hadley Centre GCMs to project future area burned. Temperature and fuel moisture were the variables best related to historical monthly area burned with 36-64% of the variance explained depending on ecozone. Our results suggest significant increases in future area burned although there are large regional variations in fire activity. This was especially true for the Canadian GCM where some ecozones show little change in area burned, however area burned was not projected to decrease in any of the ecozones modelled. On average, area burned in Canada is projected to increase by 74-118% by the end of this century in a 3 x CO2 scenario. These estimates do not explicitly take into account any changes in vegetation, ignitions, fire season length, and human activity (fire management and land use activities) that may influence area burned. However, the estimated increases in area burned would have significant ecological, economic and social impacts for Canada

    This power point presentation addressed the following topics regarding development of natural gas in eastern Canada: (1) the 18 Tcf of proven natural gas reserves at Sable Island, (2) Canadian markets benefiting from the Maritimes and Northeast Pipeline (M and NP), (3) a 20 year franchise agreement between Enbridge Gas and the government of New Brunswick, (4) the 25 year provincial franchise agreement by Sempra Atlantic Gas, and (5) Sable Island's influence on central Canada. The Sable Offshore Energy Project (SOEP) is now producing about 540,000 MMBtu/day from 6 fields. Plans for Tier 2 expansion are underway. Firm contracts for the M and NP are scheduled to transport gas from the SOEP to markets in Nova Scotia, New Brunswick, Maine and New Hampshire. Sable gas is also a potential supply for the Quebec market. Gaz Metropolitain and Enbridge have proposed to build the Cartier Pipeline from the Quebec/New Brunswick border to Quebec City. It is unlikely that Sable Island supply will directly serve the Ontario market. Canadian customers for Sable gas and M and NP service include pulp and paper companies, oil refineries, power generators and local distribution companies (LDC), with the majority of demand coming form the electric power industry. tabs., figs

  6. Energy in Canada: An overview

    International Nuclear Information System (INIS)

    Cameron, G.W.

    1991-01-01

    Recent changes in the North American natural gas industry are discussed, with a focus on how these changes will affect the ability of Alberta and Canadian natural gas supply to meet market growth. These changes include a decline in the merchant role of many of the major interstate pipelines, resulting in a larger number of smaller-sized purchasers for natural gas marketers to deal with; a greater extent of direct purchasing by local distribution companies and large industrial users, combined with a preference for spot sales rather than long-term commitments; direct marketing of uncontracted gas by many producers and brokers; a bidding type of sales process rather than a negotiated process; and price deregulation. It is foreseen that long term security of supply will again become an important factor to North American buyers, and Canada can offer substantial supplies under secure long term contracts. Marketers will have to seek new market targets such as cogeneration plants and the transportation sector. Access to pipeline transport will be one of the major factors in obtaining new markets.

    Many mule duck and Cherry Valley duck flocks in different duck-producing regions of China have shown signs of an apparently new disease designated "short beak and dwarfism syndrome" (SBDS) since 2015. The disease is characterized by dyspraxia, weight loss, a protruding tongue, and high morbidity and low mortality rates. In order to characterize the etiological agent, a virus designated SBDSV M15 was isolated from allantoic fluid of dead embryos following serial passage in duck embryos. This virus causes a cytopathic effect in duck embryo fibroblast (DEF) cells. Using monoclonal antibody diagnostic assays, the SBDSV M15 isolate was positive for the antigen of goose parvovirus but not Muscovy duck parvovirus. A 348-bp (2604-2951) VP1gene fragment was amplified, and its sequence indicated that the virus was most closely related to a Hungarian GPV strain that was also isolated from mule ducks with SBDS disease. A similar disease was reproduced by inoculating birds with SBDSV M15. Together, these data indicate that SBDSV M15 is a GPV-related parvovirus causing SBDS disease and that it is divergent from classical GPV isolates.

    Infection of clinically susceptible ducks, including cherry valley and Muscovy ducks, with a novel goose parvovirus (GPV)-related virus (N-GPV) can result in beak atrophy and dwarfism syndrome (BADS). To obtain new insights into the host range and pathogenic potential of this novel waterfowl parvovirus, cherry valley ducklings (n=20) were experimentally infected with N-GPV strain SDLC01. An equal number of ducklings served as uninfected controls. The appearance of clinical signs, histopathological changes, viral shedding, and seroconversion was monitored for 20 days post-infection. Infection status of all ducks was monitored using indirect ELISA, virus neutralization test, nested PCR, clinical indicators, and microscopic examination. Three ducks developed the typical clinical, gross, and histological changes of BADS. By study day 6, the infected ducks had seroconverted to N-GPV. The antibodies raised were neutralizing against the SDLC01 strain in vitro. Here we successfully developed an experimental infection model for studying the pathogenicity and role of N-GPV in BADS.

    Lysozyme (LZ), a bacteriolytic enzyme, is found in the egg white of many avian eggs and plays an important role in host defense; however, LZ activity in emu (Dromaius novaehollandiae) egg white is exceptionally undetectable. We cloned and characterized emu goose-type LZ (LZG) and chicken-type LZ (LZC) genes. RT-PCR analysis revealed very low LZG gene expression levels and absence of LZC gene expression in the emu oviduct. Sequencing of full-length LZG and LZC cDNAs indicated that their amino acid sequences show high similarities to ostrich LZG and LZC, respectively, with conserved catalytic residues for enzymatic activities. Whereas recombinant emu LZG prepared using Pichia pastoris exhibited similar enzyme activity as ostrich LZG, recombinant emu LZC exhibited significantly higher lytic activity than chicken LZC. We concluded that emus have functional genes for both LZG and LZC like many other avians, and the LZG gene is expressed in oviduct probably as in other ratite, however, its expression levels in egg white were low to be detected.

    A recent Canada goose (Branta canadensis) die-off at a petroleum refinery fly ash pond in Delaware was attributed to vanadium (V) toxicity. Because of the paucity of V toxicity data for wild birds, a series of studies was undertaken using the forms of V believed to have resulted in this incident. In 7-d single oral dose trials with mallard drakes (Anas platyrhynchos), the estimated median lethal dose (LD50) for vanadium pentoxide was 113 mg/kg body weight, while the LD50 for sodium metavanadate was 75.5 mg/kg. Sodium metavanadate was found to be even more potent (LD50 = 37.2 mg/kg) in male Canada geese. The most distinctive histopathological lesion of both forms of V was lympho-granulocytic enteritis with hemorrhage into the intestinal lumen. Vanadium accumulation in liver and kidney was proportional to the administered dose, and predictive analyses based on these data suggest that V concentrations of 10 μg/g dry weight (dw) in liver and 25 μg/g dw in kidney are associated with mortality (>90% confidence that exposure is >LD50) in mallards acutely exposed to sodium metavanadate. Chronic exposure to increasing dietary concentrations of sodium metavanadate (38.5 to 2651 ppm) over 67 d resulted in V accumulation in liver and kidney (25.2 and 13.6 μg/g dw, respectively), mild intestinal hemorrhage, blood chemistry changes, and evidence of hepatic oxidative stress in mallards, although some of these responses may have been confounded by food avoidance and weight loss. Dietary exposure of mallards to 250 ppm sodium metavanadate for 4 wk resulted in modest accumulation of V in liver and kidney (<5 μg/g dw) and mild intestinal hemorrhage. Based on these data and other observations, it is unlikely that chronic low-level dietary exposure to V poses a direct lethal hazard to wildlife. However, point sources, such as the V-laden fly ash pond encountered by geese at the petroleum refinery in Delaware, may pose a significant hazard to water birds.

    1996-01-01

    The Canada-Newfoundland Benefits Plan, part of the overall application to develop the Terra Nova Field off the coast of Newfoundland details the benefits to Canadians, but most particularly to residents of Newfoundland and Labrador that a vibrant petroleum industry is expected to bring. In this document the proponents commit themselves to a course of action designed to enhance the opportunities for Canadian and Newfoundland participation in the development, in accordance with the Atlantic Accord legislation. In terms of this legislation, the project proponents are obliged to perform development functions from Newfoundland, acquire goods and services for the Terra Nova Development on a 'best value' basis, but consistent with the procurement policies and procedures for benefits. The proponents must consider Canadian and, in particular, Newfoundland benefits as one of the factors in the procurement of goods and services, and require contactors and subcontractors to adhere to the development's benefits principles, objectives and commitments.

    The shelter experiences, employment history, income and social service needs utilization were examined among 124 emergency shelter users in Vancouver, British Columbia. Thirty-six (30.5%) reported this as their first experience with living in a shelter; the length of stay in the present shelter ranged from one to 90 days. Reasons for shelter use included: eviction from last place of residence, loss of job, or suffering from health problems rendering one unable to work. The highest unmet service needs were finding affordable housing and finding a job. This combination of scarcity of low-cost housing, health problems, and difficulty in finding employment have led to a situation where emergency shelters have become extended places of residence, a "home" to many.

  15. Distributed learning or medical tourism? A Canadian residency program's experience in global health.

    Science.gov (United States)

    Kelly, Kate; McCarthy, Anne; McLean, Laurie

    2015-01-01

    Global health experiences (GHEs) are becoming increasingly prevalent in surgical residency education. Although it may seem intuitive that participation in GHEs develops CanMEDS competencies, this has not been studied in depth in surgery. The purpose of this study is (1) to explore if and how otolaryngology-head and neck surgery (OHNS) resident participation in GHEs facilitates the development of CanMEDS competencies and (2) to develop an OHNS GHE tool to facilitate the integration of CanMEDS into GHE participation and evaluation. An online survey explored the GHEs of current and past OHNS residents in Canada. Based on the data collected and a literature review, a foundational tool was then created to (1) enable OHNS residents to structure their GHEs into CanMEDS-related learning objectives and (2) enable OHNS program directors to more effectively evaluate residents' GHEs with respect to CanMEDS competencies. Participants' GHEs varied widely. These experiences often contributed informally to the development of several CanMEDS competencies. However, few residents had concrete objectives, rarely were CanMEDS roles clearly incorporated, and most residents were not formally evaluated during their experience. Residents felt they achieved greater learning when predeparture objectives and postexperience reflections were integrated into their GHEs. Although GHEs vary widely, they can serve as valuable forums for developing CanMEDS competencies among participating residents. Without clear objectives that adhere to the CanMEDS framework or formal assessment methods however, residents in GHEs risk becoming medical tourists. The use of an objective and evaluation tool may facilitate the creation of predeparture learning objectives, encourage self-reflection on their GHE, and better enable program directors to evaluate residents participating in GHEs.

    Medical residency programs are traditionally known for long working hours, which can be associated with a poor quality of sleep and daytime sleepiness. However, few studies have focused on this theme. Our objective was to investigate sleep quality, daytime sleepiness, and their relation with anxiety, social phobia, and depressive symptoms. This cross-sectional observational study involved 59 psychiatry residents. The Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (ESS) were used to measure the quality of sleep and excessive daytime sleepiness ([EDS] and ESS > 10), respectively. Among the 59 psychiatry residents, 59.3% had poor sleep quality (PSQI > 5) and 28.8% had EDS. Poor sleep quality was associated with higher EDS (P = 0.03) and the year of residency program (P = 0.03). Only 20% of residents with poor sleep had consulted at least once for sleep problems; 54.2% had used medications for sleep; and 16.9% were using medications at the time of interview. Only 30% obtained medication during medical consultations. Poor sleep was associated with irregular sleep hours (P = 0.001) and long periods lying down without sleep (P = 0.03). Poor sleep quality was also associated with high scores of anxiety symptoms (P Psychiatry residents frequently have poor sleep quality and EDS. Considering that sleep disorders can affect quality of life, predispose to metabolic syndrome, and be associated with worse performance at work, attention to this clinical problem is needed. © The Author(s) 2016.

    In Kuwait, 21 residency training programs were offered in the year 2011; however, no data is available regarding the criteria of selecting residents for these programs. This study aims to provide information about the importance of these criteria. A self-administered questionnaire was used to collect data from members (e.g. chairmen, directors, assistants …etc.) of residency programs in Kuwait. A total of 108 members were invited to participate. They were asked to rate the importance level (scale from 1 to 5) of criteria that may affect the acceptance of an applicant to their residency programs. Average scores were calculated for each criterion. Of the 108 members invited to participate, only 12 (11.1%) declined to participate. Interview performance was ranked as the most important criteria for selecting residents (average score: 4.63/5.00), followed by grade point average (average score: 3.78/5.00) and honors during medical school (average score: 3.67/5.00). On the other hand, receiving disciplinary action during medical school and failure in a required clerkship were considered as the most concerning among other criteria used to reject applicants (average scores: 3.83/5.00 and 3.54/5.00 respectively). Minor differences regarding the importance level of each criterion were noted across different programs. This study provided general information about the criteria that are used to accept/reject applicants to residency programs in Kuwait. Future studies should be conducted to investigate each criterion individually, and to assess if these criteria are related to residents' success during their training.

    Care by Design™ (CBD) (Canada), a model of coordinated team-based primary care, was implemented in long-term care facilities (LTCFs) in Halifax, Nova Scotia, Canada, to improve access to and continuity of primary care and to reduce high rates of transfers to emergency departments (EDs). This was an observational time series before and after the implementation of CBD (Canada). Participants are LTCF residents with 911 Emergency Health Services calls from 10 LTCFs, representing 1424 beds. Data were abstracted from LTCF charts and Emergency Health Services databases. The primary outcome was ambulance transports from LTCFs to EDs. Secondary outcomes included access (primary care physician notes in charts) and continuity (physician numbers and contacts). After implementation of CBD (Canada), transports from LTCFs to EDs were reduced by 36%, from 68 to 44 per month (P = .01). Relational and informational continuity of care improved with resident charts with ≥10 physician notes, increasing 38% before CBD to 55% after CBD (P = .003), and the median number of chart notes increased from 7 to 10 (P = .0026). Physicians contacted before 911 calls and onsite assessment increased from 38% to 54% (P = .01) and 3.7% to 9.2% (P = .03), respectively, before CBD to after CBD. A 34% reduction in overall transports from LTCFs to EDs is likely attributable to improved onsite primary care, with consistent physician and team engagement and improvements in continuity of care. © Copyright 2016 by the American Board of Family Medicine.

    The practice followed in planning, preparing and conducting offsite nuclear emergency exercises in the Province of Ontario, Canada, is described. In addition, some of the main issues that arise during this process are discussed, as well as Canadian experience in dealing with them. The planning process starts with basic decisions on the aim, scope and duration of the exercise. It proceeds through selection of the exercise objectives and participants, the development of scenarios and incident lists culminating in a master scenario and a master incident list, and finally, the production of control inputs. Preparations include the setting up of a planning organization, making arrangements for exercise control and evaluation, and the required logistics. Some aspects of international exercises are also covered, based upon experience with joint exercises with the U.S.A

    The radiological surveillance program of the Department of National Health and Welfare is conducted for the purpose of determining levels of environmental radioactivity in Canada and assessing the resulting population exposures. Following major changes to the CAMECO Port Hope operations to reduce uranium emissions, a study was initiated to measure uranium levels in air in the community. Studies continued on lung cancer and domestic exposure to radon, and current levels of cesium-137 in caribou, a major source of food in northern communities. The movement of tritium on the Ottawa and St. Lawrence rivers was studied following an accidental release into the Ottawa River. Monitoring continued of fallout contamination from Chernobyl in imported foods. All measurements recorded during 1988 were below the limits recommended by the International Commission on Radiological Protection. (14 refs., 14 figs., 15 tabs.)

    Bernanke [Bernanke, Ben S. Irreversibility, uncertainty, and cyclical investment. Quarterly Journal of Economics 98 (1983), 85-106.] shows how uncertainty about energy prices may induce optimizing firms to postpone investment decisions, thereby leading to a decline in aggregate output. Elder and Serletis [Elder, John and Serletis, Apostolos. Oil price uncertainty.] find empirical evidence that uncertainty about oil prices has tended to depress investment in the United States. In this paper we assess the robustness of these results by investigating the effects of oil price uncertainty in Canada. Our results are remarkably similar to existing results for the United States, providing additional evidence that uncertainty about oil prices may provide another explanation for why the sharp oil price declines of 1985 failed to produce rapid output growth. Impulse-response analysis suggests that uncertainty about oil prices may tend to reinforce the negative response of output to positive oil shocks. (author)

    2002-01-01

    As many jurisdictions move towards more retributive measures as a means to address public discontent with crime, a parallel movement has developed in regard to restorative justice. This article presents three restorative initiatives currently in use in Canada. Each initiative addresses offender behavior and community engagement at a different point in the justice continuum. The use of Sentencing Circles is an example of how restorative justice principles can be instituted at the front end, prior to an offender becoming lodged in the system. The Restorative Justice Options to Parole Suspension project demonstrates how community engagement can assist in preventing offenders from being returned to the system once they have achieved conditional release. The Circles of Support and Accountability project has enlisted the support of professionally supported volunteers in the community reintegration of high-risk sexual offenders. These initiatives are presented within a framework of effective correctional interventions and increased empowerment for a variety of stakeholders. Copyright 2002 John Wiley & Sons, Ltd.

    1993-01-01

    This paper provides an estimate of household gasoline demand in Canada by applying a detailed model to pool time-series (1969-1988) and cross-sectional provincial data. The model recognises three major behavioural changes that households can make in response to gasoline price changes: drive fewer miles, purchase fewer cars, and buy more fuel-efficient vehicles. In the model, fuel economy is treated in considerable detail. The two components of the fuel economy of new cars sold-the technical fuel efficiency of various classes of cars and the distribution of new car sales according to their interior volume rather than their weight - are estimated as functions of economic variables. Car manufacturers are assumed to improve the technical fuel economy according to their expectation of consumer's response to future changes in gasoline prices and general economic conditions.

    Participation in scholarly activity is an important tenet of residency training and is firmly entrenched in Canada since the introduction of CANMEDS roles by the Royal College of Physicians and Surgeons. As Canadian residency programs transition to competency-based training, it will remain important to understand how to best implement and encourage scholarly pursuits among resident trainees. The objective of this study was to understand the experiences, attitudes, and barriers that surgical residents face when pursuing research during their training. An anonymous, cross-sectional, self-report questionnaire was administered to chief residents of all English-speaking urology programs in Canada in 2015. Questions were open- and closed-ended, including an agreement score based on a five-point Likert scale. Questions addressed residents' involvement in and attitudes towards research, as well as their perceptions of the utility of research involvement during training. The residents were also asked about the support they received and potential areas to improve the attainment of this competency. Descriptive and correlative statistics were used to analyze the responses. There was a 100% overall response rate to the questionnaire. This study revealed that Canadian urology residents have a high rate of participation in scholarly work, with the vast majority (94%) publishing at least one manuscript with a mean of four papers. Despite this, there appeared to be significant variation in the respondent's experiences, including protected time for research. Furthermore, many residents appeared unconvinced of the importance of research involvement, with only 51% agreement that participation was important to their overall training. As well, a significant number of residents reported largely external, rather than internal, motivations for research participation, such as attaining a preferred fellowship (66% agreement). While the majority of respondents felt (66% agreement) that the

    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.

A recent Special Report in the New England Journal of Medicine, however, has described resident educational programs to date as prescriptive, noting an absence of innovation in education. Current aims of contemporary medical resident education are thus being directed at ensuring quality in learning as well as in patient care. Achievement and work-motivation theories attempt to explain people's choice, performance, and persistence in tasks. Expectancy Theory as one such theory was reviewed in detail, appearing particularly applicable to surgical residency training. Correlations between Expectancy Theory as a work-motivation theory and residency education were explored. Understanding achievement and work-motivation theories affords an opportunity to gain insight into resident motivation in training. The application of Expectancy Theory in particular provides an innovative perspective into residency education. Afforded are opportunities to promote the development of programmatic methods facilitating surgical resident motivation in education. Keywords: learning, education, achievement

    Theory has predicted, and many experimental studies have confirmed, that resident plant species richness is inversely related to invisibility. Likewise, potential invaders that are functionally similar to resident plant species are less likely to invade than are those from different functional groups. Neither of these ideas has been tested in the context of an operational prairie restoration. Here, we tested the hypotheses that within tallgrass prairie restorations (1) as seed mix species richness increased, cover of the invasive perennial forb, Canada thistle (Cirsium arvense) would decline; and (2) guilds (both planted and arising from the seedbank) most similar to Canada thistle would have a larger negative effect on it than less similar guilds. Each hypothesis was tested on six former agricultural fields restored to tallgrass prairie in 2005; all were within the tallgrass prairie biome in Minnesota, USA. A mixed-model with repeated measures (years) in a randomized block (fields) design indicated that seed mix richness had no effect on cover of Canada thistle. Structural equation models assessing effects of cover of each planted and non-planted guild on cover of Canada thistle in 2006, 2007, and 2010 revealed that planted Asteraceae never had a negative effect on Canada thistle. In contrast, planted cool-season grasses and non-Asteraceae forbs, and many non-planted guilds had negative effects on Canada thistle cover. We conclude that early, robust establishment of native species, regardless of guild, is of greater importance in resistance to Canada thistle than is similarity of guilds in new prairie restorations.

    Background Based on regional and anecdotal reports, there is concern that vitamin D–deficiency rickets is persistent in Canada despite guidelines for its prevention. We sought to determine the incidence and clinical characteristics of vitamin D–deficiency rickets among children living in Canada. Methods A total of 2325 Canadian pediatricians were surveyed monthly from July 1, 2002, to June 30, 2004, through the Canadian Paediatric Surveillance Program to determine the incidence, geographic distribution and clinical profiles of confirmed cases of vitamin D-deficiency rickets. We calculated incidence rates based on the number of confirmed cases over the product of the length of the study period (2 years) and the estimates of the population by age group. Results There were 104 confirmed cases of vitamin D–deficiency rickets during the study period. The overall annual incidence rate was 2.9 cases per 100 000. The incidence rates were highest among children residing in the the north (Yukon Territory, Northwest Territories and Nunavut). The mean age at diagnosis was 1.4 years (standard deviation [SD] 0.9, min–max 2 weeks–6.3 years). Sixty-eight children (65%) had lived in urban areas most of their lives, and 57 (55%) of the cases were identified in Ontario. Ninety-two (89%) of the children had intermediate or darker skin. Ninety-eight (94%) had been breast-fed, and 3 children (2.9%) had been fed standard infant formula. None of the breast-fed infants had received vitamin D supplementation according to current guidelines (400 IU/d). Maternal risk factors included limited sun exposure and a lack of vitamin D from diet or supplements during pregnancy and lactation. The majority of children showed clinically important morbidity at diagnosis, including hypocalcemic seizures (20 cases, 19%). Interpretation Vitamin D–deficiency rickets is persistent in Canada, particularly among children who reside in the north and among infants with darker skin who are breast

    Paulino, Arnold C.; Kurtz, Elizabeth

    2008-01-01

    Purpose: To review the results of the recent American College of Radiology (ACR) in-training examinations in radiation oncology and to provide information regarding the examination changes in recent years. Methods and Materials: A retrospective review of the 2004 to 2007 ACR in-training examination was undertaken. Results: The number of residents taking the in-training examination increased from 2004 to 2007, compatible with the increase in the number of radiation oncology residents in the United States and Canada. The number of questions decreased from approximately 510 in 2004 and 2005, to 405 in 2006 and 360 in 2007, most of these changes were in the clinical oncology section. Although the in-training examination showed construct validity with resident performance improving with each year of additional clinical oncology training, it did so only until Level 3 for biology and physics. Several changes have been made to the examination process, including allowing residents to keep the examination booklet for self-study, posting of the answer key and rationales to questions on the ACR Website, and providing hard copies to residency training directors. In addition, all questions are now A type or multiple choice questions with one best answer, similar to the American Board of Radiology written examination for radiation oncology. Conclusion: Several efforts by the ACR have been made in recent years to make the examination an educational tool for radiation oncology residents and residency directors

    Internet resources play an important role in how medical students access information related to residency programs.Evaluating program websites is necessary in order to provide accurate information for applicants and provide information regarding areas of website improvement for programs. To date, dermatology residency websites (D  WS) have not been evaluated.This paper evaluates dermatology residency websites based on availability of predefined measures. Using the FREIDA (Fellowship and Residency Electronic Interactive Database) Online database, authors searched forall accredited dermatology program websites. Eligible programs were identified through the FREIDA Online database and had a functioning website. Two authors independently extracted data with consensus or third researcher resolution of differences. This data was accessed and archived from July 15th to July 17th, 2015.Primary outcomes measured were presence of content on education, resident and faculty information, program environment, applicant recruitment, schedule, salary, and website quality evaluated using an online tool (WooRank.com). Out of 117 accredited dermatology residencies, 115 had functioning webpages. Of these, 76.5% (75) had direct links found on the FRIEDA Online database. Most programs contained information on education, faculty, program environment, and applicant recruitment. However, website quality and marketing effectiveness were highly variable; most programs were deemed to need improvements in the functioning of their webpages. Also, additional information on current residents and about potential away rotations were lacking from most websites with only 52.2% (60) and 41.7% (48) of programs providing this content, respectively. A majority of dermatology residency websites contained adequate information on many of the factors we evaluated. However, many were lacking in areas that matter to applicants. We hope this report will encourage dermatology residencyprograms

    2007-01-01

    Taxi and limousine service plays an important role in the movement of people within a city. In 2004, the total revenue in this industry in Canada was $1.305 billion, and an estimated 35,339 carriers served the industry. In Canada, economic and safety regulations of taxi supply were imposed in most cities during the 1930s and 1940s and continue to this date. Although the industry is regulated, the competition law also applies. The appropriateness of these regulations continues to be challenged and regulatory reforms in the major cities in Canada have concentrated their efforts on increasing the rate of services, improving the quality of vehicles and enhancing the training of taxi drivers. Indicators for the 1999-2004 period reveal that the taxi and limousine industry in Canada did not perform very well. Revenue increased by only 1.7 per cent per year and margins deteriorated by -1.78 per cent together with the operating ratio. The purpose of this paper was to examine the taxi and limousine industry in Canada. First, the structure of the industry in Canada was examined followed by a review of the economic regulation of the industry. Recent regulatory developments in Canada and in other countries were then reviewed with arguments for or against deregulation. 28 refs., 2 tabs

  7. Canada's nuclear non-proliferation policy

    International Nuclear Information System (INIS)

    1985-01-01

    Canada's non-proliferation and safeguards policy has two objectives: 1) to promote the emergence of a more effective and comprehensive international non-proliferation regime; and 2) to assure the Canadian people and the international community that Canadian nuclear exports will not be used for any nuclear explosive purpose. By emphasizing the key role of the NPT, by promoting reliance upon and improvements in the IAEA safeguards system, by treating nuclear weapon and non-nuclear weapon states alike regarding Canadian nuclear exports, by working for new approaches covering the sensitive phases (e.g. reprocessing) of the nuclear fuel cycle, Canada's policy promotes attainment of the first objective. The latter objective is served through the network of bilateral nuclear agreements that Canada has put into place with its nuclear partners. Those agreements provide assurance that Canada's nuclear exports are used solely for legitimate, peaceful, nuclear energy production purposes. At the same time, Canada, having formulated its non-proliferation and safeguards policy during the period 1945 to 1980, has recognized that it has gone as far as it can on its own in this field and that from this point on any further changes should be made on the basis of international agreement. The Canadian objective in post-INFCE forums such as the Committee on Assurances of Supply is to exert Canada's best efforts to persuade the international community to devise a more effective and comprehensive international non-proliferation regime into which Canada and other suppliers might subsume their national requirements

    1998-01-01

    Petro-Canada is a dominant player in the petroleum industry in Western Canada as well as on the Grand Banks offshore Newfoundland. This report presents a review of operations, provides detailed statements of the corporation's finances, and a wealth of information of interest to shareholders. The report states that in 1997 Petro-Canada achieved record financial results, following a dramatic turnaround over the past five years. Net earnings for 1997 were $306 million, a $59 million increase over 1996. The company's share price appreciated 34 per cent in 1997 and was one of the most heavily traded stocks in Canada. The company plans to maximize shareholder value by reducing its interests in conventional oil from mature fields in western Canada and by re-investing the proceeds in natural gas development. Petro-Canada is also committed to an expansion that will double production at the Syncrude oil sands plant over the next decade and has tested large in-situ oil sands resources for potential development in northeastern Alberta. On the Atlantic coast too, Petro-Canada is delivering leadership with increasing production from Hibernia, and final approvals in place to proceed with development of the Terra Nova field. International operations are also contributing to the Corporation's profitability by delivering new production from oil fields offshore Norway and from the Sahara Desert in North Africa. tabs., figs

  9. Uranium in Canada: Billion-dollar industry

    International Nuclear Information System (INIS)

    Whillans, R.T.

    1989-01-01

    In 1988, Canada maintained its position as the world's leading producer and exporter of uranium; five primary uranium producers reported concentrate output containing 12,400 MT of uranium, or about one-third of Western production. Uranium shipments made by these producers in 1988 exceeded 13,200 MT, worth Canadian $1.1 billion. Because domestic requirements represent only 15% of current Canadian output, most of Canada's uranium production is available for export. Despite continued market uncertainty in 1988, Canada's uranium producers signed new sales contracts for some 14,000 MT, twice the 1987 level. About 90% of this new volume is with the US, now Canada's major uranium customer. The recent implementation of the Canada/US Free Trade agreement brings benefits to both countries; the uranium industries in each can now develop in an orderly, free market. Canada's uranium industry was restructured and consolidated in 1988 through merger and acquisition; three new uranium projects advanced significantly. Canada's new policy on nonresident ownership in the uranium mining sector, designed to encourage both Canadian and foreign investment, should greatly improve efforts to finance the development of recent Canadian uranium discoveries

    Waterfowl parvovirus (WPV) infection causes high mortality and morbidity in both geese (Anser anser) and Muscovy ducks (Cairina moschata), resulting in significant losses to the waterfowl industries. The VP3 protein of WPV is a major structural protein that induces neutralizing antibodies in the waterfowl. However, B-cell epitopes on the VP3 protein of WPV have not been characterized. To understand the antigenic determinants of the VP3 protein, we used the monoclonal antibody (mAb) 4A6 to screen a set of eight partially expressed overlapping peptides spanning VP3. Using western blotting and an enzyme-linked immunosorbent assay (ELISA), we localized the VP3 epitope between amino acids (aa) 57 and 112. To identify the essential epitope residues, a phage library displaying 12-mer random peptides was screened with mAb 4A6. Phage clone peptides displayed a consensus sequence of YxRFHxH that mimicked the sequence 82Y/FNRFHCH88, which corresponded to amino acid residues 82 to 88 of VP3 protein of WPVs. mAb 4A6 binding to biotinylated fragments corresponding to amino acid residues 82 to 88 of the VP3 protein verified that the 82FxRFHxH88 was the VP3 epitope and that amino acids 82F is necessary to retain maximal binding to mAb 4A6. Parvovirus-positive goose and duck sera reacted with the epitope peptide by dot blotting assay, revealing the importance of these amino acids of the epitope in antibody-epitope binding reactivity. We identified the motif FxRFHxH as a VP3-specific B-cell epitope that is recognized by the neutralizing mAb 4A6. This finding might be valuable in understanding of the antigenic topology of VP3 of WPV.

    In this study, we cloned the gene encoding goose-type (G-type) lysozyme with chitinase (Ra-ChiC) activity from Ralstonia sp. A-471 genomic DNA library. This is the first report of another type of chitinase after the previously reported chitinases ChiA (Ra-ChiA) and ChiB (Ra-ChiB) in the chitinase system of the moderately thermophilic bacterium, Ralstonia sp. A-471 and also the first such data in Ralstonia sp. G-type lysozyme gene. It consisted of 753 bp nucleotides, which encodes 251 amino acids including a putative signal peptide. This ORF was modular enzyme composed of a signal sequence, chitin-binding domain, linker, and catalytic domain. The catalytic domain of Ra-ChiC showed homologies to those of G-type lysozyme (glycoside hydrolases (GH) family 23, 16.8%) and lysozyme-like enzyme from Clostridium beijerincki (76.1%). Ra-ChiC had activities against ethylene glycol chitin, carboxyl methyl chitin, and soluble chitin but not against the cell wall of Micrococcus lysodeikticus. The enzyme produced alpha-anomer by hydrolyzing beta-1,4-glycosidic linkage of the substrate, indicating that the enzyme catalyzes the hydrolysis through an inverting mechanism. When N-acetylglucosamine hexasaccharide [(GlcNAc)6] was hydrolyzed by the enzyme, the second and third glycosidic linkage from the non-reducing end were split producing (GlcNAc)2 + (GlcNAc)4 and (GlcNAc)3 + (GlcNAc)3 of almost the same concentration in the early stage of the reaction. The G-type lysozyme hydrolyzed (GlcNAc)6 in an endo-splitting manner, which produced (GlcNAc)3 + (GlcNAc)3 predominating over that to (GlcNAc)2 + (GlcNAc)4. Thus, Ra-ChiC was found to be a novel enzyme in its structural and functional properties.

    To understand the role of His101 in protein structure stabilization of goose-type (G-type) lysozyme, we conducted thermal unfolding/refolding experiments using native G-type lysozyme from ostrich egg white (nOEL), the recombinant G-type lysozyme (rOEL), and the mutant lysozyme, in which His101 is mutated to alanine (H101A-OEL). Thermal stability on lytic activity and in-gel refolding experiments provided similar profiles for all three OELs. Circular dichroism (CD) spectroscopy was used to determine the secondary structure of three OELs as a function of temperature. Unfolding/refolding experiments (30-90 °C) monitored by CD spectroscopy revealed an unfolding transition at 65-67 °C and a complete refolding at almost the same temperature. Notably, a slightly lower thermal stability was observed for H101A-OEL, corresponding to the calculated difference in transition free energy of thermal unfolding (∆∆G m ) between rOEL and H101A-OEL of -0.63 kcal/mol. To assess the effects of H101A mutation on the electrostatic behavior, we examined the pH-activity profile of the three OELs. nOEL and rOEL exhibit bimodal relationship between pH and lytic activity showing optima at pH 3.0 and 7.0, while optima for H101A-OEL activity were pH 4.0 and 6.0. Electrostatic environment surrounding His101 was affected by the H101A mutation resulting in the slightly lower thermal stability.

    Simulation has become a valuable tool in medical education, and several specialties accept or require simulation as a resource for resident training or assessment as well as for board certification or maintenance of certification. This study investigates current simulation resources and activities in US otolaryngology residency programs and examines interest in advancing simulation training and assessment within the specialty. Web-based survey. US otolaryngology residency training programs. An electronic web-based survey was disseminated to all US otolaryngology program directors to determine their respective institutional and departmental simulation resources, existing simulation activities, and interest in further simulation initiatives. Descriptive results are reported. Responses were received from 43 of 104 (43%) residency programs. Simulation capabilities and resources are available in most respondents' institutions (78.6% report onsite resources; 73.8% report availability of models, manikins, and devices). Most respondents (61%) report limited simulation activity within otolaryngology. Areas of simulation are broad, addressing technical and nontechnical skills related to clinical training (94%). Simulation is infrequently used for research, credentialing, or systems improvement. The majority of respondents (83.8%) expressed interest in participating in multicenter trials of simulation initiatives. Most respondents from otolaryngology residency programs have incorporated some simulation into their curriculum. Interest among program directors to participate in future multicenter trials appears high. Future research efforts in this area should aim to determine optimal simulators and simulation activities for training and assessment as well as how to best incorporate simulation into otolaryngology residency training programs. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

    Canada has a great national asset in its ability to generate electricity economically from its abundant hydro, coal, and uranium resources. Its nuclear industry has an excellent product. Despite lack of orders for now, the CANDU will be a competitive force when the reactor market recovers. Canada has a proven record of reliability for electricity trade with the United States. There appear to be some opportunities for plants in Canada dedicated to the export of electric power. The federal government is prepared to work closely with the provinces to develop projects which will be attractive to customers in the United States

To measure academic achievement, the American Medical Education (AME) examination was administered to residents. The Hospital of Saint Raphael, General Surgery Residency Program, New Haven, Connecticut. Both instruments were administered to residents during protected core curriculum time. Core faculty were administered the LSI on an individual basis. Surgical residents of the Hospital of Saint Raphael's General Surgery Residency Program and 6 core faculty members Analysis of resident learning style preference revealed Converging as the most commonly occurring style for residents (7) followed by Accommodating (5), Assimilating (3), and Diverging (1). The predominant learning style for core faculty was also Converging (4) with 2 Divergers. The average score for the Convergers on the AME was 62.6 compared with 42 for the next most frequently occurring learning style, Accommodators. In this surgical residency program, a preferred learning style for residents seems to exist (Converging), which confirms what previous studies have found. Additionally, residents with this learning style attained a higher average achievement score as measured by the AME. Also, core faculty share the same preferential learning style as this subset of residents.

    Traumatic events in one's younger years can have an impact on how an individual copes with later life. One traumatic experience for Jewish individuals was the Holocaust. Some of these people are moving into long-term care facilities. It was within this context that the research question emerged: What are Holocaust survivor residents' perceptions of a life lived as they move into a long-term care facility? For this qualitative study, Holocaust survivors were individually interviewed. Findings emphasize that nursing care needs to ensure that Holocaust survivor residents participate in activities, receive timely health care, and receive recognition of their life experiences.

  3. Understanding gasoline pricing in Canada

    International Nuclear Information System (INIS)

    2001-04-01

    This brochure is designed to help consumers understand how gasoline is priced and explained why prices increase, fluctuate and vary by location, city or region. The price of a litre of gasoline reflects the costs of crude oil, refining, retailing and taxes. Taxes are usually the largest single component of gasoline prices, averaging 40 to 50 per cent of the pump price. The cost of crude oil makes up another 35 to 45 per cent of the price. Refining costs make up 10 to 15 per cent while the remaining 5 to 10 per cent represents retail costs. Gasoline retailers make a profit of about 1 cent per litre. The latest network technology allows national and regional retail chains to constantly monitor price fluctuations to change their prices at gasoline stations at a moments notice to keep up with the competition and to protect their market shares. Several government studies, plus the Conference Board of Canada, have reported that competition is working in favour of Canadian motorists. This brochure also explained the drawbacks of regulating crude and pump prices with the reminder that crude prices were regulated in the 1970s with many negative consequences. 2 tabs., 1 fig

    1992-01-01

    After three years of evaluating prospects and negotiating with government and industry representatives, Gulf Canada established its first joint venture in the Russian Federation with Komineft, a production association from the Komi autonomous republic. Komineft has a 50% share of the venture, and the rest is shared equally between Gulf and British Gas. The operating area is at the Vozey and Upper Vozey fields in the Timan-Pechora Basin, some 1,500 km northeast of Moscow just inside the Arctic Circle. An attractive feature of the Upper Vozey project is low development costs of ca $2/bbl. In the Vozey field, the venture will set up an enhanced oil recovery demonstration project to test techniques perfected in Alberta. About 60 Canadians are involved on the project, and headquarters are in Usinsk, ca 100 km south of the oil fields. In the first half of 1992, oil production in the first phase of the venture averaged around 10,000 bbl/d and continues to increase

  5. Emerging Churches in Post-Christian Canada

    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.

    A review of operations in 1998 and financial information from Gulf Canada Resources Limited is provided to keep shareholders abreast of company performance. Gulf Canada Resources Limited explores for, develops, produces and markets conventional and synthetic crude oil, natural gas and natural gas liquids. In 1998, the company's main operating centres were in western Canada (where it owns a nine per cent interest in the Syncrude Joint Venture), Indonesia, the North Sea and Australia. The report summarizes the company's energy resource activities, presents a detailed review of operations, and provides consolidated financial statements, and common share information. Although Gulf Canada Resources sold $ 1.2 billion worth of non-producing assets during the year, year end proved reserves of 838 million barrels of oil equivalent were less than ten per cent lower than a year earlier, reflecting reserve additions of 100 million barrels of oil equivalent. tabs., figs

  9. Canada's nuclear non-proliferation policy

    International Nuclear Information System (INIS)

    1982-05-01

    Canada's non-proliferation safeguards policy has two objectives: 1) to promote a more effective and comprehensive international non-proliferation regime; and 2) to ensure that Canadian nuclear exports will not be used for any nuclear explosive purpose. By emphasizing the key role of the Non-Proliferation Treaty, promoting reliance upon and improvements in the IAEA safeguards system, treating nuclear weapon and non-weapon states alike, and working for new approaches covering reprocessing, Canada promotes attainment of the first objective. The second is served through the network of bilateral nuclear agreements that Canada has put into place with its partners. The Canadian objective in post-INFCE forums is to persuade the international community to devise a more effective and comprehensive non-proliferation regime into which Canada and other suppliers may subsume their national requirements

    2013-03-01

    Dementia is a progressive, life-limiting illness. People with the condition who move into a care home deserve palliative care. This article discusses an interprofessional pilot workshop for direct care providers held in a care home in British Columbia, Canada. The workshop aimed to incorporate a palliative approach into dementia care for residents. Workshop development, teaching strategies, evaluation and outcomes are shared. The four-hour workshop was structured to promote critical reflection and challenge participants to consider that people with dementia and their families need palliative care much earlier than during the last days of life. Commitment to change statements gathered as part of the workshop indicated that participation increased knowledge, skill and confidence to incorporate a palliative approach into care for people with advanced dementia and their families.

  14. From Residency to Lifelong Learning.

    Science.gov (United States)

    Brandt, Keith

    2015-11-01

    The residency training experience is the perfect environment for learning. The university/institution patient population provides a never-ending supply of patients with unique management challenges. Resources abound that allow the discovery of knowledge about similar situations. Senior teachers provide counseling and help direct appropriate care. Periodic testing and evaluations identify deficiencies, which can be corrected with future study. What happens, however, when the resident graduates? Do they possess all the knowledge they'll need for the rest of their career? Will medical discovery stand still limiting the need for future study? If initial certification establishes that the physician has the skills and knowledge to function as an independent physician and surgeon, how do we assure the public that plastic surgeons will practice lifelong learning and remain safe throughout their career? Enter Maintenance of Certification (MOC). In an ideal world, MOC would provide many of the same tools as residency training: identification of gaps in knowledge, resources to correct those deficiencies, overall assessment of knowledge, feedback about communication skills and professionalism, and methods to evaluate and improve one's practice. This article discusses the need; for education and self-assessment that extends beyond residency training and a commitment to lifelong learning. The American Board of Plastic Surgery MOC program is described to demonstrate how it helps the diplomate reach the goal of continuous practice improvement.

    2015-03-01

    Full Text Available Twelve wetlands occurring in four different ecozones in Uttar Pradesh (UP, India, were selected for studying the winter composition and dynamics of avian populations. Wetland information was collected from office records of the UP Forest department. Bird populations were estimated by transect method and block-in-flock-in-sector method for woodland and aquatic birds, respectively. Across the twelve selected wetlands a total of 486,182 individuals belonging to 161 species of birds on 15,592 ha were recorded during the winter of 2010-11. The data were analyzed to assess the relationship between wetland characteristics and avian populations. Aquatic vegetation, surrounding vegetation, water availability and climate were found as important factors related to avian populations. January was found to be the peak of bird assemblage, while winter times before and after January were the waxing and waning period, respectively. Species richness and species diversity of aquatic birds varied between 18-58 and 1.90-3.20, respectively, and of all bird species between 23-109, and 1.73-3.81, respectively. The density of aquatic birds ranged between 17-384 ha-1. The most common migratory birds in wetlands were Northern Pintail, Common Teal and Greylag Goose. Common resident birds included Asian Openbill, Darter, Little Egret, Common Coot, Little Cormorant, Grey Heron, Purple Heron, Indian Pond Heron, Common Moorhen, Purple Swamphen, Cattle Egret, Indian Sarus Crane and White-throated Kingfisher. For improved conservation of aquatic avian fauna, management prescriptions are suggested for wetlands under current management which could also be extended to other wetlands, whereas conservation of avian fauna to be the emphasis.

  5. Level of economic development of the country of origin and work-to-family conflict after migration to Canada.

    Science.gov (United States)

    Montazer, Shirin; Young, Marisa

    2017-03-01

    Using a sample of employed adults living in Canada, this article examines patterns and antecedents of work-to-family conflict (WFC) among immigrants, relative to the native-born. We test whether the origin-country- or intermediary country of residence- country-level economic development, and length of residence in Canada interact to affect WFC differentially for immigrants. We hypothesize that origin-country economic development impacts the value and transferability of immigrants' capital in the host country. Discrepancies between the two results in underemployment, stressful work experiences, and thus greater WFC for immigrants, relative to the native-born. Results indicate greater WFC among recent and established immigrants from less developed countries and among established immigrants from developed countries. This finding, however, is conditioned by gender and particularly strong among established immigrant men from less developed countries, compared to their female counterparts.

    The student costs of residency interviewing are of increasing concern but limited current information is available. Updated, more detailed information would assist students and residency programs in decisions about residency selection. The study objective was to measure the expenses and time spent in residency interviewing by the 2016 graduating class of the University of Kansas School of Medicine and assess the impact of gender, regional campus location, and primary care application. All 195 students who participated in the 2016 National Residency Matching Program (NRMP) received a 33 item questionnaire addressing interviewing activity, expenses incurred, time invested and related factors. Main measures were self-reported estimates of expenses and time spent interviewing. Descriptive analyses were applied to participant characteristics and responses. Multivariate analysis of variance (MANOVA) and chi-square tests compared students by gender, campus (main/regional), and primary care/other specialties. Analyses of variance (ANOVA) on the dependent variables provided follow-up tests on significant MANOVA results. A total of 163 students (84%) completed the survey. The average student reported 38 (1-124) applications, 16 (1-54) invitations, 11 (1-28) completed interviews, and spent $3,500 ($20-$12,000) and 26 (1-90) days interviewing. No significant differences were found by gender. After MANOVA and ANOVA analyses, non-primary care applicants reported significantly more applications, interviews, and expenditures, but less program financial support. Regional campus students reported significantly fewer invitations, interviews, and days interviewing, but equivalent costs when controlled for primary care application. Cost was a limiting factor in accepting interviews for 63% and time for 53% of study respondents. Students reported investing significant time and money in interviewing. After controlling for other variables, primary care was associated with significantly

  7. Increasing turbine vendor competition in Canada

    International Nuclear Information System (INIS)

    Magee, J.T.

    2008-01-01

    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

  8. Flood insurance in Canada: implications for flood management and residential vulnerability to flood hazards.

    Science.gov (United States)

    Oulahen, Greg

    2015-03-01

    Insurance coverage of damage caused by overland flooding is currently not available to Canadian homeowners. As flood disaster losses and water damage claims both trend upward, insurers in Canada are considering offering residential flood coverage in order to properly underwrite the risk and extend their business. If private flood insurance is introduced in Canada, it will have implications for the current regime of public flood management and for residential vulnerability to flood hazards. This paper engages many of the competing issues surrounding the privatization of flood risk by addressing questions about whether flood insurance can be an effective tool in limiting exposure to the hazard and how it would exacerbate already unequal vulnerability. A case study investigates willingness to pay for flood insurance among residents in Metro Vancouver and how attitudes about insurance relate to other factors that determine residential vulnerability to flood hazards. Findings indicate that demand for flood insurance is part of a complex, dialectical set of determinants of vulnerability.

    2009-12-01

    The purpose of this study was to explore the drinking culture of elderly Korean immigrants in Canada. Using a focus group approach, qualitative data were collected from 19 elderly Korean immigrants (14 men; 5 women) residing in Canada. Data were analyzed using the techniques of grounded theory. The findings indicated that elderly Korean immigrants did not dramatically change their understanding of drinking or their ways of drinking. Instead, they modified their drinking behavior in accordance with the social and legal environment of their new country. In particular, Canadian alcohol policies, including the higher cost of alcohol, lower accessibility, and strict law enforcement, discouraged excessive drinking. Policy implications and recommendations for future research are presented.

  10. Factors affecting residency rank-listing: A Maxdiff survey of graduating Canadian medical students

    Directory of Open Access Journals (Sweden)

    Forgie Melissa

    2011-08-01

    Full Text Available Abstract Background In Canada, graduating medical students consider many factors, including geographic, social, and academic, when ranking residency programs through the Canadian Residency Matching Service (CaRMS. The relative significance of these factors is poorly studied in Canada. It is also unknown how students differentiate between their top program choices. This survey study addresses the influence of various factors on applicant decision making. Methods Graduating medical students from all six Ontario medical schools were invited to participate in an online survey available for three weeks prior to the CaRMS match day in 2010. Max-Diff discrete choice scaling, multiple choice, and drop-list style questions were employed. The Max-Diff data was analyzed using a scaled simple count method. Data for how students distinguish between top programs was analyzed as percentages. Comparisons were made between male and female applicants as well as between family medicine and specialist applicants; statistical significance was determined by the Mann-Whitney test. Results In total, 339 of 819 (41.4% eligible students responded. The variety of clinical experiences and resident morale were weighed heavily in choosing a residency program; whereas financial incentives and parental leave attitudes had low influence. Major reasons that applicants selected their first choice program over their second choice included the distance to relatives and desirability of the city. Both genders had similar priorities when selecting programs. Family medicine applicants rated the variety of clinical experiences more importantly; whereas specialty applicants emphasized academic factors more. Conclusions Graduating medical students consider program characteristics such as the variety of clinical experiences and resident morale heavily in terms of overall priority. However, differentiation between their top two choice programs is often dependent on social/geographic factors

  11. International plastic surgery missions: a framework for resident education using the CanMEDS competencies.

    Science.gov (United States)

    White, Colin P; Lecours, Catherine; Bortoluzzi, Patricia; Caouette-Laberge, Louise; Ying, Yvonne

    2013-10-01

    Residency education has shifted over the past decade in an attempt to graduate well-rounded physicians. There is a recognition that a physician's abilities must extend beyond medical knowledge. The Royal College of Physicians and Surgeons of Canada introduced the CanMEDS physician competency framework in 2005. The framework provides 7 areas of competencies that are aimed at providing improved patient care. These competencies are medical expert, communicator, collaborator, manager, health advocate, scholar, and professional. Teaching and evaluating many of these competencies is often challenging for residency training programs. We believe that international surgical missions provide a prime opportunity to teach and evaluate all CanMEDS' roles.Plastic surgery is a field with many different organizations involved in international surgery. Many plastic surgery training programs offer opportunities for residents to become involved in these international surgical missions. Through these trips, residents gain surgical experience, see a variety and volume of clinical cases, and have the opportunity to travel to a foreign country and experience different cultures. We believe that international plastic surgery surgical missions also provide an exceptional micro environment for the teaching of CanMEDS roles. Using examples from residents' personal experiences on international plastic surgery missions to China, Mali, and Cambodia, we describe the benefits of these missions in transferring the CanMEDS competencies to resident training.

  12. Reimagining Haj Khalil v. Canada

    Reem Bahdi

    2009-02-01

    Full Text Available This paper emphasizes the importance of cultural competence for tort law by analyzing the Federal Court’s decision in Haj Khalil v. Canada. Given that this symposium in honour of Rose Voyvodic’s life and work is entitled “Re-Imagining Access to Justice,” this paper asks “how do the principles of cultural competence allow us to think about the facts of the Haj Khalil differently. In particular, what would a cause in fact analysis look like if it were informed by the principles of cultural competence?” My analysis proceeds by “reading the silences” or focusing on the unstated assumptions and unexplored elements of Haj Khalil’s story to bring into focus factors relevant to factual causation which remain largely unexplored or undervalued by the Federal Court. An examination of the facts that framed Haj Khalil`s claim against immigration officials through a culturally competent lens would open the possibility of a different understanding of causation as it arises on the facts of the case. While Canadian courts have emphasized the importance of social context for fair judgment, they have not fully come to grips with the implications of social context for judicial decision-making. This is particularly the case within negligence law which remains vexed by the need to maintain an objective standard while simultaneously recognizing the importance of context and circumstance to particular claims. Cet article souligne l’importance de la compétence culturelle pour le droit de la responsabilité civile délictuelle en analysant le jugement Haj Khalil c. Canada de la Cour Fédérale. Vu que ce symposium en honneur de la vie et de l’oeuvre de Rose Voyvodic est intitulé « Re-Imagining Access to Justice», cet article pose la question «comment les principes de compétence culturelle nous permettent-ils de concevoir différemment les faits de Haj Khalil. En particulier, comment se présenterait la causalité si l’analyse des faits

  13. Teaching residents to write a research paper.

    Science.gov (United States)

    Coleridge, S T

    1993-09-01

    Medical writing and publications are important in developing a scholarly basis for residency programs and in providing a learning experience for both resident and faculty mentors. Residency directors must provide the stimulus and support for both faculty and residents' varied creative activities. This support manifests itself in a commitment to scholarly activity (including a dedicated research person), the procurement of available research materials, the establishment of a process or plan for beginning a research project, and the development of a method for rewarding or recognizing faculty and residents who produce scholarly works. Some osteopathic residency programs may need to train faculty in research skills at the same time that residents are learning to write. Trained faculty are better models and coaches for residents engaged in research. Beginning with a fundamental, but disciplined, writing program, both faculty and residents may learn methods for sharing new knowledge or acquiring those skills necessary to critically analyze the medical literature.

    The role of the internal medicine chief resident includes various administrative, academic, social, and educational responsibilities, fulfillment of which prepares residents for further leadership tasks. However, the chief resident position has historically only been held by a few residents. As fourth-year chief residents are becoming less common, we considered a new model for rotating third-year residents as the chief resident. Online surveys were given to all 29 internal medicine residents in a single university-based program after implementation of a leadership curriculum and specific job description for the third-year chief resident. Chief residents evaluated themselves on various aspects of leadership. Participation was voluntary. Descriptive statistics were generated using SPSS version 21. Thirteen junior (first- or second-year) resident responses reported that the chief residents elicited input from others (mean rating 6.8), were committed to the team (6.8), resolved conflict (6.7), ensured efficiency, organization and productivity of the team (6.7), participated actively (7.0), and managed resources (6.6). Responses from senior residents averaged 1 point higher for each item; this pattern repeated itself in teaching evaluations. Chief resident self-evaluators were more comfortable running a morning report (8.4) than with being chief resident (5.8). The feasibility of preparing internal medicine residents for leadership roles through a rotating PGY-3 (postgraduate year) chief residency curriculum was explored at a small internal medicine residency, and we suggest extending the study to include other programs.

    Investment in Canada's wind sector is projected to reach $8 billion by 2012, and growth of the sector is expected to create over 16,000 jobs. Canada's wind energy capacity grew by 54 per cent in 2005 alone, aided in part by supportive national policies and programs such as the Wind Power Production Incentive (WPPI); the Canadian Renewable Conservation Expense (CRCE) and Class 43.1 Capital Cost Allowance; and support for research and development. Major long-term commitments for clean power purchases, standard offer contracts and renewable portfolio standards in several provinces are encouraging further development of the wind energy sector. This paper argued that the development of a robust Canadian wind turbine manufacturing industry will enhance economic development, create opportunities for export; and mitigate the effects of international wind turbine supply shortages. However, it is not known whether Canadian wind turbine firms are positioned to capitalize on the sector's recent growth. While Canada imports nearly all its large wind turbine generators and components, the country has technology and manufacturing strengths in advanced power electronics and small wind systems, as well as in wind resource mapping. Wind-diesel and wind-hydrogen systems are being developed in Canada, and many of the hybrid systems will offer significant opportunities for remote communities and off-grid applications. Company partnerships for technology transfer, licensing and joint ventures will accelerate Canada's progress. A recent survey conducted by Industry Canada and the Canadian Wind Energy Association (CanWEA) indicated that the total impact of wind energy related expenditures on economic output is nearly $1.38 billion for the entire sector. Annual payroll for jobs in Canada was estimated at $50 million, and substantial employment growth in the next 5 years is expected. Canada offers a strong industrial supply base capable of manufacturing wind turbine generators and
