  1. The recommissioning of Montreal's Palais des Congres; Le recommissioning du Palais des congres de Montreal

    Poirier, M. [Palais des Congres, Montreal, PQ (Canada); Deschamps, J.F. [Pageau Morel et Associes, Montreal, PQ (Canada)

    2006-12-15

    An addition was constructed onto the Palais des Congres building in Montreal in 2002. When the energy performance of the newly recommissioned building failed to meet the expectations of the construction contractor, an Energy Savings Commission was created with a mandate was to reduce energy consumption by 25 per cent over a 3 to 5 year time period, representing a savings of $500,000 per year. The objective was to make advantageous changes that would not compromise occupant comfort or interior air quality. The Committee identified areas of possible improvements in the building's heating, ventilating and air conditioning (HVAC) system. Improvements in lighting systems and humidity control were also investigated. The Committee identified necessary upgrades and evaluated the changes in terms of technical feasibility, financial profit and sustainability. The Committee was also responsible for acquiring the authorization needed to proceed with the investment and implement change. This paper listed the energy saving measures along with the associated savings in electricity and natural gas. It also listed the associated reduction in greenhouse gas emissions. The energy saving measures undertaken by the Committee were based on 3 fundamental principles which included turning off equipment that was not being used in different areas of the building; optimizing the energy use of equipment; and, replacing or modifying inefficient equipment. In November 2005, the Palais des Congres hosted the Energy Efficiency Week, during which time it made use of CANMET's Diagnostic Agent for Building Operators (DABO) software package to achieve energy savings. A program aimed at training employees in energy efficiency was also implemented and feedback on key issues was acquired. Hydro-Quebec also contributed $25,000 towards the energy analysis performed by the Committee. The objective of saving $500,000 in energy costs over a 3 to 5 year period was met. 3 tabs., 1 fig.

    A study of 15 fathers and their 16 sons in an italophone community in Montreal (Canada) focused on the usage of Italian, French, and English in communication between generations and in a variety of activities. Data were drawn from 45 hours of taped conversation in home and work settings, which included 4,848 instances of language contact. Of the…

  3. Analyse des attitudes envers les sciences chez des eleves du secondaire d'origine haitienne de milieux defavorises de la region de Montreal

    Fils-Aime, Nestor

    Having in perspective the slight representativeness of students, from Haitian background, from the most unprivileged sections of the great region of Montreal in the scientific fields in High School and in the choices of career, this study intends to examine the effect of the individual characteristics as well as the associated factors related to the familial, scholastic, socio-economic, and cultural environment upon the attitudes of those students toward sciences. The analysis of the datum is based on the results of a questionnaire focusing on the socio-demographic profile of a group of students from fourth and fifth year attending two multiethnic High Schools of the North-Crown of Montreal as well as on the interviews with fifteen of those students who are from a haitian background. There were also interviews with some parents, a member of a community organism, some staff members of some schools as well as some Haitian-Quebecer professionals and scientists, in order to have a critical viewpoint upon the different positions expressed by the fifteen students. The Bronfenbrenner's ecosystemic model (1979, 1986) has been used as scope of reference allowing to draw the prominent aspects from the attitudes toward science in the students, from haitian background. The synthesis of ideas expressed by different interviewee reveals the existence of a environment not much enhancing the value of sciences around of students, from Haitian background. The socio-economic conditions, the familial practices, the ethnocultural status as well as some individual representations of sciences contribute to create and maintain some attitudes very little committed to sciences in those students. The study shows how much it is urgent to demystify the sciences by breaking with some stereotypes that prevent some categories of students from acceding to sciences. It also commands to politicians, concerning education, to be more open to ethnocultural differences and to explore some dynamic ways in

  6. The metro area of Montreal.

    1986-10-01

    Montreal, one of the most civilized and cosmopolitan of North American cities, is the 2nd city in Canada in size and the largest French-speaking city. Of the 2.8 million people who lived there at census time in 1981, 45% chose both French and English as their official language, 41% chose French, and 1% used some other language. Fully 68% of Montreal residents said their mother tongue was French, and 68% also said they spoke French at home. The importance of bilingualism to the business culture of Montreal cannot be overemphasized. In the last decade, French-Canadians have taken an increasingly stronger role in business. Upper-middle-class suburbs that as little as 10 years ago had only 10% of their residents who were of French-Canadian descent now have as many as 50-60% of their residents who are French-Canadians. Most residents of Montreal willingly learn 2 languages. US firms should assume that all representatives who are sent to Montreal should be fluent in both French and English. Montreal's 2,828,349 people create a population density of 1004.9 persons per square kilometer. Montreal has 665 census tracts, which are described in the Metropolitan Atlas Series. Nearly 62% of Montreal's population fall between the ages of 20 and 64--the prime working ages. Although Montreal is 79% Catholic, it does not have the high fertility levels often associated with Catholic areas. There were 1,026,920 households in Montreal in 1981 with an average of 2.7 persons per household. 71% of these were census family households. Montreal had 1,026,895 occupied dwellings in 1985 with an average of 5 rooms each. About 71% of the population aged 15 and over that were not in school were in the labor force; 41% of the labor force was female. The largest employment category for men was manufacturing (16%) and the largest for women was clerical work (39%).

  7. Montreal Modern: Retro Culture and the Modern Past in Montreal

    Kristian Handberg

    2015-03-01

    Full Text Available Through analyses of the retro scenes in Montreal, Canada, the article discusses retro culture's role as cultural memory. It is shown how Montreal's cultural identity is formed by memories of modern culture such as the Red-light and Sin City reputation of the illicit nightlife of the 1940s and 1950s, and the space age modernism of the 1960s following the Expo 67 and Quebec's Quiet Revolution. This is reflected in the city's thriving retro culture through the study of two groups of retro shops. In circulating specific memories and objects in a specific context, retro is an important negotiation of the past in the present. Especially, it is stated that the retro culture displays "local accents" and a new focus on the specificities of modern culture giving a revaluation to a previously overlooked identity such as the Quebecit.

  8. 1959 : Borden bails on Montreal question

    Anon.

    2008-01-01

    In 1959, following months of hearings, the Borden Royal Commission on Oil and Gas was unwilling to grant western producers the access to the Montreal refinery market. Rather than building a pipeline to Montreal, the Commission urged a national policy supporting the export of Canadian crude without license, and encouraging the use of Canadian crude in markets that already have pipeline access to it, including the west coast, Midwest and Ontario. The Commission recommended that the Canadian oil and gas industry take measures to enlarge its share of the United States market and asked that petroleum product retailers displace 50,000 barrels per day of products refined from imported crude in Montreal and sold in Ontario with a similar volume of products refined from Canadian crude. Proponents of the Commission's report stated that exports to the United States were essential to the Canadian oil industry and that a crude oil line to Montreal was not economic. Other key events in 1959 were listed in this article. Alberta and Southern sought approval to export 460 million cubic feet of gas per day to California. Dome Petroleum Limited suggested that the Arctic Islands could hold reserves of up to 100 billion barrels, and a planned nuclear explosion to free oil from the Athabasca oil sands was called off by the federal government for political reasons. 1 tab., 1 fig

  9. Greek women and broken nerves in Montreal.

    Dunk, P

    1989-05-01

    In this paper, I examine the importance of class, ethnicity and gender in the causation and meaning of somatization for Greek women in Montreal. I argue that nevra--a form of psychosocial distress experienced by many of the women--is a phenomenon of the poor working conditions, low wages and gender relations in the Greek community. Data is based on interviews with 100 Greek families in Montreal and 45 patients in two different clinical settings. Comparing results with material on nervios and nerves from Latin America and the United States, I concur with Low (1985) that nerves should be viewed as a 'culturally-interpreted symptom' rather than a 'culture bound syndrome'. It is further suggested that the importance of social and material conditions and gender relations in mediating the cultural interpretation must be stressed. Failure to do so often results in the medicalization of nevra and the creation of a chronic sick role for the patient.

  10. UV Impacts Avoided by the Montreal Protocol

    Newman, Paul; McKenzie, Richard

    2010-01-01

    Temporal and geographical variabilities in the future "World Expected" UV environment are compared with the "World Avoided", which would have occurred without the Montreal Protocol on protection of the ozone layer and its subsequent amendments and adjustments. Based on calculations of clear-sky UV irradiances, the effects of the Montreal Protocol have been hugely beneficial to avoid the health risks, such as skin cancer, which are associated with high UV, while there is only a small increase in health risks, such as vitamin D deficiency, that are associated with low UV. However, interactions with climate change may lead to changes in cloud and albedo, and possibly behavioural changes which could also be important.

  11. Montreal Protocol Benefits simulated with CCM SOCOL

    T. Egorova

    2013-04-01

    Full Text Available Ozone depletion is caused by the anthropogenic increase of halogen-containing species in the atmosphere, which results in the enhancement of the concentration of reactive chlorine and bromine in the stratosphere. To reduce the influence of anthropogenic ozone-depleting substances (ODS, the Montreal Protocol was agreed by Governments in 1987, with several Amendments and Adjustments adopted later. In order to assess the benefits of the Montreal Protocol and its Amendments and Adjustments (MPA on ozone and UV radiation, two different runs of the chemistry-climate model (CCM SOCOL have been carried out. The first run was driven by the emission of ozone depleting substances (ODS prescribed according to the restrictions of the MPA. For the second run we allow the ODS to grow by 3% annually. We find that the MPA would have saved up to 80% of the global annual total ozone by the end of the 21st century. Our calculations also show substantial changes of the stratospheric circulation pattern as well as in surface temperature and precipitations that could occur in the world without MPA implementations. To illustrate the changes in UV radiation at the surface and to emphasise certain features, which can only be seen for some particular regions if the influence of the cloud cover changes is accounted for, we calculate geographical distribution of the erythemally weighted irradiance (Eery. For the no Montreal Protocol simulation Eery increases by factor of 4 to 16 between the 1970s and 2100. For the scenario including the Montreal Protocol it is found that UV radiation starts to decrease in 2000, with continuous decline of 5% to 10% at middle latitudes in the both Northern and Southern Hemispheres.

  12. The Montreal Protocol for Identification of Amusia.

    Vuvan, D T; Paquette, S; Mignault Goulet, G; Royal, I; Felezeu, M; Peretz, I

    2018-04-01

    The Montreal Battery for the Evaluation of Amusia (MBEA; Peretz, Champod, & Hyde Annals of the New York Academy of Sciences, 999, 58-75, 2003) is an empirically grounded quantitative tool that is widely used to identify individuals with congenital amusia. The use of such a standardized measure ensures that the individuals tested will conform to a specific neuropsychological profile, allowing for comparisons across studies and research groups. Recently, a number of researchers have published credible critiques of the usefulness of the MBEA as a diagnostic tool for amusia. Here we argue that the MBEA and its online counterpart, the AMUSIA tests (Peretz et al. Music Perception, 25, 331-343, 2008), should be considered steps in a screening process for amusia, rather than standalone diagnostic tools. The goal of this article is to present, in detailed and easily replicable format, the full protocol through which congenital amusics should be identified. In providing information that has often gone unreported in published articles, we aim to clarify the strengths and limitations of the MBEA and to make recommendations for its continued use by the research community as part of the Montreal Protocol for Identification of Amusia.

  13. Historic cohort study in Montreal's fur industry.

    Guay, D; Siemiatycki, J

    1987-01-01

    A historic cohort mortality study was carried out among two groups of male workers in the Montreal fur industry: 263 dressers and dyers and 599 fur garment manufacturers. The first group is exposed to a very wide variety of chemicals used in tanning, cleaning, and dyeing fur, including substances considered to be carcinogenic and/or mutagenic. The second group is exposed to residue from the dressing and dyeing stage and to respirable fur dust. The cohorts consisted of all active members of two unions as of January 1, 1966. The mean age of the workers was 43.2 and the mean number of years since first employment 14.1. The follow-up period was from January 1, 1966, to December 31, 1981; 95% of the workers were successfully traced. Observed deaths were compared with those expected based on mortality rates of the population of metropolitan Montreal. Standardized mortality ratios (SMRs) for the manufacturers were significantly low, probably because of the ethnic composition of the cohort and a healthy worker effect. SMRs for the dressers and dyers were also low, but not as low as for the manufacturers. When attention was restricted to the French Canadians in the cohort, the observed deaths were close to the expected; there was a noteworthy excess of colorectal cancer (four observed, 0.8 expected) for dressers and dyers. Apart from this weak suggestive evidence, the results did not indicate any excess mortality risks in the fur industry. However, because of the relatively small number of expected and observed deaths in the cohort and especially among the heavily exposed dressers and dyers, the confidence intervals around SMR estimates were wide and excess risks cannot be ruled out.

  15. ‘THE BIGGEST MISTAKE GOD EVER MADE WAS TO CREATE JUNKIES’: UNSAFE INJECTION PRACTICES, HEALTH CARE DISCRIMINATION AND OVERDOSE DEATHS IN MONTREAL, CANADA

    Jozaghi, Ehsan

    2013-01-01

    Full Text Available Despite the existence of prevention programmes in Montreal, Canada, injection drug users (IDUs continue to share their injection drug equipment. This practice has led to an increase in the incidences of HIV and Hepatitis C (HCV among IDUs since 2003. The present study was conducted to explore factors contributing to the increased risks of this morbidity. Semi-structured qualitative interviews were conducted as drug users were actively involved in their routine activities. The participants’ narratives indicate that IDUs in Montreal are involved in risky injection behaviour that increases HIV, HCV and bacterial transmission. Moreover, IDUs in Montreal are at an increased risk of overdose and death when they are forced to inject in public washrooms or alleys. In addition, many IDUs have placed the general public at risk by discarding their used needles in public parks, sidewalks and public washrooms. Furthermore, many IDUs in Montreal have faced discrimination and are refused treatment by the health care system. Micro- environmental factors, such as a paucity of safe injection sites, inaccessibility of injection equipment and discrimination all seem to be contributing factors in recent increases in HIV and HCV in Montreal.Malgré les programmes de prévention qui existent à Montréal, Canada, les utilisateurs de drogues injectables (UDI continuent de partager leurs seringues.

  19. Hydrofluorocarbon (HFC) Scenarios, Climate Effects and the Montreal Protocol

    Velders, G. J. M.; Fahey, D. W.; Daniel, J. S.

    2016-12-01

    The Montreal Protocol has reduced the use of ozone-depleting substances by more than 95% from its peak levels in the 1980s. As a direct result the use of hydrofluorocarbons (HFCs) as substitute compounds has increased significantly. National regulations to limit HFC use have been adopted recently in the European Union, Japan and USA, and four proposals have been submitted to amend the Montreal Protocol to substantially reduce growth in HFC use. The Parties of the Montreal Protocol have discussed these proposals during their meetings in 2016. The effects of the national regulations and Montreal Protocol amendment proposals on climate forcings and surface temperatures will be presented. Global scenarios of HFC emissions reach 4.0-5.3 GtCO2-eq yr-1 in 2050, which corresponds to a projected growth from 2015 to 2050 which is 9% to 29% of that for CO2 over the same time period. In 2050, in percent of global HFC emissions, China ( 30%), India and the rest of Asia ( 25%), Middle East and northern Africa ( 10%), and USA ( 10%) are the principal source regions; and refrigeration and stationary air conditioning are the major use sectors. Calculated baseline emissions are reduced by 90% in 2050 by implementing the North America Montreal Protocol amendment proposal. This corresponds to a reduction in surface temperature attributed to HFCs from 0.1 oC to 0.04 oC in 2050 and from 0.3-0.4 oC to 0.02 oC in 2100.

  20. Tuberculosis and homelessness in Montreal: a retrospective cohort study

    2011-01-01

    Background Montreal is Canada's second-largest city, where mean annual tuberculosis (TB) incidence from 1996 to 2007 was 8.9/100,000. The objectives of this study were to describe the epidemiology of TB among homeless persons in Montreal and assess patterns of transmission and sharing of key locations. Methods We reviewed demographic, clinical, and microbiologic data for all active TB cases reported in Montreal from 1996 to 2007 and identified persons who were homeless in the year prior to TB diagnosis. We genotyped all available Mycobacterium tuberculosis isolates by IS6110 restriction fragment length polymorphism (IS6110-RFLP) and spoligotyping, and used a geographic information system to identify potential locations for transmission between persons with matching isolates. Results There were 20 cases of TB in homeless persons, out of 1823 total reported from 1996-2007. 17/20 were Canadian-born, including 5 Aboriginals. Homeless persons were more likely than non-homeless persons to have pulmonary TB (20/20), smear-positive disease (17/20, odds ratio (OR) = 5.7, 95% confidence interval (CI): 1.7-20), HIV co-infection (12/20, OR = 14, 95%CI: 4.8-40), and a history of substance use. The median duration from symptom onset to diagnosis was 61 days for homeless persons vs. 28 days for non-homeless persons (P = 0.022). Eleven homeless persons with TB belonged to genotype-defined clusters (OR = 5.4, 95%CI: 2.2-13), and ten potential locations for transmission were identified, including health care facilities, homeless shelters/drop-in centres, and an Aboriginal community centre. Conclusions TB cases among homeless persons in Montreal raise concerns about delayed diagnosis and ongoing local transmission. PMID:22034944

    2015-03-01

    Full Text Available Greg Robinson’s article “Whispers of the Unspeakable: New York and Montreal Newspaper Coverage of the Oscar Wilde Trials in 1895,” originally published in 2010 in the French-language journal Rue des Beaux Arts, no. 24 (2010, is here republished and—with much gratitude—translated (for the original text, please see http://www.oscholars.com/RBA/twenty-four/24.7/Articles.htm. Robinson’s transnational study focuses on how reading the specific language of newspaper reports of the Oscar Wilde case, literally from a distance, from places less emotionally attached to and nationally distinct from the scandal’s epicenter in London, England, provides insight into “the state of everyday public knowledge and discussion of (homosexuality, at least west of the Atlantic”; thus Robinson’s fascinating research, which involves numerous newspapers—from the elite New York Times to the New York Herald, from the Montreal Daily Star to the French-language papers of Quebec—concludes that the popular press, read transnationally, offers key insights into the developing attitudes toward and levels of interest in the newly forming identity of the “homosexual” across societies.

  2. Phosphorus cycling in Montreal's food and urban agriculture systems.

    Metson, Geneviève S; Bennett, Elena M

    2015-01-01

    Cities are a key system in anthropogenic phosphorus (P) cycling because they concentrate both P demand and waste production. Urban agriculture (UA) has been proposed as a means to improve P management by recycling cities' P-rich waste back into local food production. However, we have a limited understanding of the role UA currently plays in the P cycle of cities or its potential to recycle local P waste. Using existing data combined with surveys of local UA practitioners, we quantified the role of UA in the P cycle of Montreal, Canada to explore the potential for UA to recycle local P waste. We also used existing data to complete a substance flow analysis of P flows in the overall food system of Montreal. In 2012, Montreal imported 3.5 Gg of P in food, of which 2.63 Gg ultimately accumulated in landfills, 0.36 Gg were discharged to local waters, and only 0.09 Gg were recycled through composting. We found that UA is only a small sub-system in the overall P cycle of the city, contributing just 0.44% of the P consumed as food in the city. However, within the UA system, the rate of recycling is high: 73% of inputs applied to soil were from recycled sources. While a Quebec mandate to recycle 100% of all organic waste by 2020 might increase the role of UA in P recycling, the area of land in UA is too small to accommodate all P waste produced on the island. UA may, however, be a valuable pathway to improve urban P sustainability by acting as an activity that changes residents' relationship to, and understanding of, the food system and increases their acceptance of composting.

  3. Thirty Years After Bill 101: A Contemporary Perspective on Attitudes Towards English and French in Montreal

    Ruth Kircher

    2014-06-01

    Full Text Available Abstract This paper presents a 2007 study that was conducted amongst 147 young anglophone, francophone and allophone Montrealers in order to shed light on their attitudes towards English and French in terms of status and solidarity. The study made use of both a questionnaire and a matched-guise experiment. The findings indicate that while a certain amount of status was attributed to French, most likely as a result of language policy and planning measures such as Bill 101, significantly more status was attributed to English—most likely a result of the utilitarian value that the language holds as the global lingua franca. Regarding the solidarity dimension, it appears that while the respondents recognised the social desirability of having an affective attachment to the French language, at a more private level, they held more positive attitudes towards English. These can tentatively be explained in terms of the respondents’ social identity. Résumé L’article ci-dessous présente une recherche menée en 2007 parmi 147 étudiants montréalais (anglophones, francophones et allophones qui eut pour objectif d’examiner leurs attitudes envers l’anglais comparé au français en terme de statut et de solidarité. Un questionnaire et une étude des faux-couples furent utilisés comme méthodes de recherche. Les résultats indiquent qu’un certain statut est attribué au français, ce qui est probablement une conséquence des lois langagières comme la Loi 101. Néanmoins, un statut plus important est attribué à l’anglais, ce qui est probablement une conséquence de sa valeur utilitaire comme lingua franca globale. En ce qui concerne la dimension de la solidarité, bien que les jeunes montréalais semblent conscients de l’importance sociale de se sentir attachés à la langue française, lorsque l’on considère un aspect plus personnel, ils tendent à manifester des attitudes plus positives envers l’anglais. Ces attitudes plus positives

    Erdos, Caroline; Ferdinand, Jae-Marie

    2017-01-01

    Abstract The foundations for language and literacy are set in utero when babies hear the tone of their mother’s voice (1). There is strong evidence of a positive relationship between early literacy experiences and language and academic outcomes (2). Unfortunately, many parents do not know about the benefits of reading to and with young children, and many children enter school without the basic skills needed to learn to read and succeed. Physicians who have contact with young families are in a distinctive position to promote reading, though despite its evidence base, it has not yet become a universal intervention. A short description of the projects at the Montreal Children’s Hospital is provided. PMID:29479189

  6. Clinical applications of positron emission tomography at Montreal Neurological Institute

    Morgan, P.P.

    1983-01-01

    The Montreal Neurological Institute occupies a leading position in positron emission tomography (PET) of the brain with the help of the following three techological gains: they have acquired a 'Therascan' positron emission tomograph manufactured by Atomic Energy of Canada Ltd.; also, a 'Baby Cyclotron' manufactured by Japan Steel Works Ltd.; and they have written a computer program to display the results in colour. Four short-lived isotopes are used; 11 C, 15 O, 18 F, 13 N. Studies of the oxygen uptake of tumours, their glucose metabolism (as monitored by 18 F labelled 2-fluoro-2-deoxyglucose), and their uptake of therapeutic agents, provide valuable research and diagnostic information. PET is also being used to study epilepsy and cerebrovascular disease

  7. The Montreal Protocol's multilateral fund and sustainable development

    Luken, Ralph; Grof, Tamas

    2006-01-01

    The 1987 Montreal Protocol is widely seen as a global environmental accord that has produced tangible results in terms of reductions in ozone-depleting substances. In addition, there have been other benefits, largely unrecognized and undocumented, that can best be characterized in a sustainable development framework based on a review of 50 out of 931 projects implemented over a 13 year period by one of the four implementing agencies of the Multilateral Fund for the Implementation of the Montreal Protocol. All investment projects have reduced ozone depleting potential and global warming potential. Some projects have reduced atmospheric emissions and contamination of groundwater. Other projects have increased the competitiveness of enterprises in domestic and international markets and have sustained and in a few cases created employment opportunities. Others, fewer in number, have potentially contributed to environmental problems, have initially created difficulties in maintaining productivity and quality standards and have decreased the number of employment opportunities because of the need to rationalize manufacturing processes. The potential contributions from Multilateral Fund investment projects to sustainable development could probably have been amplified with project design guidance for the technical staffs of all three implementing agencies executing investment projects. In thinking about other multilateral environmental agreements, one can see the need for similar guidance for Global Environment Facility funded projects supporting the focal areas of climate change, international waters, ozone depletion and persistent organic pollutants. Some of them have the potential to generate multiple beneficial impacts in addition to their stated environmental objective if designed and implemented within a sustainable development framework.

    The Second World War began in the summer of 1939 and spurred atomic science in the direction of weapons development. The United Kingdom (U.K.) was far ahead until about the summer of 1941 at which time the United States (U.S.) began to have serious interest in atomic weapons. Seen from Europe, the U.S. was a greater distance from the theatre of war and was deemed to be a safer place to conduct atomic research. In addition to good research centres it also had greater financial, manpower, and material resources. Early attempts at full collaboration between the U.K. and the U.S. met with little success and this led to the formation of a joint British-Canadian atomic weapons effort in 1942, with research laboratories located in Montreal, which were well up and running by spring 1943. The Montreal laboratory (ML) initially was administered by the National Research Council (NRC) and scientific direction was provided by the U.K. The ML was the foundation from which the Canadian nuclear industry evolved to the present time. Interest in atomic weapons development by the U.S. had been greatly accelerated by the Japanese attack on Pearl Harbour on 7 December 1941. By the beginning of 1943 it was spending 10 times as much as the U.K. on atomic weapons research. From then on, the U.S. set the Allied agenda for the development of atomic weapons, in varying degrees of collaboration with the U.K. and Canada. This spending which grew to about $2B by the middle of 1945, was directed by the U.S. Army Corps of Engineers under the Manhattan Project, officially established on 13 August 1942, and led by Gen. Leslie R. Groves From 17 September 1942. (author)

  9. Strengthening the Montreal Protocol: Does it cool down the greenhouse?

    Den Elzen, M.G.J.; Swart, R.J.; Rotmans, J.

    1992-01-01

    Strengthening of the Montreal Protocol is recently being negotiated in London in 1990 in order to achieve further reductions of the regulated CFCs and to include possibly more substances. The implications of different policies with respect to control of ozone depleting substances for climate change are analysed, including the proposed substitution by HCFCs and HFCs, carbon tetrachloride and methylchloroform. A special halocarbon module was developed within the framework of RIVM's Integrated Model to Assess the Greenhouse Effect (IMAGE). IMAGE is a parametrized science based policy model and has been developed to give policy agencies a concise overview of the quantitative aspects of the greenhouse problem, to evaluate various policy options concerning climate change and to serve as a means of communication. It is concluded, from simulations with the halocarbon module, that it is of primary importance to achieve a further reduction of the regulated CFCs compared to the Montreal Protocol with compliance by as many countries as possible. From the perspective of the greenhouse effect the inclusion of longer lived halocarbons, such as carbon tetrachloride and HCFC-22 in the protocol come second. The application of methylchloroform, halons and HCFCs and HFCs with lower global warming potentials (GWPs) than HCFC-22 contributes only marginally to the greenhouse effect in comparison with the much more important greenhouse gases carbon dioxide, methane, ozone and nitrous oxide. Especially if further growth of the total production of HCFCs after complete replacement of the present CFCs can be avoided by using these alternatives with a lower GWP, these substances could therefore be tolerated in a transition period, from the perspective of global warming. 13 figs., 3 tabs., 29 refs

    Data sharing is becoming more of a requirement as technologies mature and as global research and communications diversify. As a result, researchers are looking for practical solutions, not only to enhance scientific collaborations, but also to acquire larger amounts of data, and to access specialized datasets. In many cases, the realities of data acquisition present a significant burden, therefore gaining access to public datasets allows for more robust analyses and broadly enriched data exploration. To answer this demand, the Montreal Neurological Institute has announced its commitment to Open Science, harnessing the power of making both clinical and research data available to the world (Owens, 2016a,b). As such, the LORIS and CBRAIN (Das et al., 2016) platforms have been tasked with the technical challenges specific to the institutional-level implementation of open data sharing, including: Comprehensive linking of multimodal data (phenotypic, clinical, neuroimaging, biobanking, and genomics, etc.)Secure database encryption, specifically designed for institutional and multi-project data sharing, ensuring subject confidentiality (using multi-tiered identifiers).Querying capabilities with multiple levels of single study and institutional permissions, allowing public data sharing for all consented and de-identified subject data.Configurable pipelines and flags to facilitate acquisition and analysis, as well as access to High Performance Computing clusters for rapid data processing and sharing of software tools.Robust Workflows and Quality Control mechanisms ensuring transparency and consistency in best practices.Long term storage (and web access) of data, reducing loss of institutional data assets.Enhanced web-based visualization of imaging, genomic, and phenotypic data, allowing for real-time viewing and manipulation of data from anywhere in the world.Numerous modules for data filtering, summary statistics, and personalized and configurable dashboards.

  12. Being a Creative and an Immigrant in Montreal

    Diane-Gabrielle Tremblay

    2016-09-01

    Full Text Available Work on creative careers has focused on the main national populations, while little research has addressed the situation of artists and creators of immigrant origin or different ethnic groups to determine whether they have the same access to work and employment rights. To respond for a call for research on different ethnic groups in the cultural sector, or the ethnic consequences of the individualization of careers, we therefore undertook research on the creative careers of immigrants in Montreal. We were interested in how they emerged as an artist, how they developed their careers, the access and rights they have in terms of support to their career, as McRobbie seems to indicate that ethnicity adds its “own weight to the life chances of those who are attempting to make a living in these fields. We found that these immigrant artists consider their main difficulties to be the lack of social networks, access to various forms of support to compensate for financial risks and difficulties in finding a job. We conclude with a few suggestions: measures to facilitate networking for immigrants, more training and information on government programs, mentoring support, as well as the support from community organizations, associations, and programs.

  13. [Rape by 2 assaillants and gang rape in Montreal].

    Lamontagne, Y; Boyer, R; Lamontagne, C; Giroux, J

    1984-11-01

    A survey was conducted in 230 cases of rape and rape attempts heard in the Judicial District of Montreal between January 1975 and May 1978. Data were compiled from the 30 assaults including two or more assaillants. Results show that in cases of rape committed by two men the aggressors are older than gang rapists, meet the victim mainly in her flat or in a bar, and rape her in her own home, in a car or a hotel. In these cases, voyeurism seems to be an important factor since, most of the time, rape is committed by only one of the two aggressors. On the other hand, gang rapists are younger, meet the victim in public places, on the street or when she is hitch-hiking and attack her in one of the aggressors' house, in public places or on the street. Exhibitionism seems more present in this group of rapists. For both groups the victims are mainly single, younger than the aggressors and have diverse occupations. Finally, regarding the legal outcome half of the subjects were liberated or acquitted in both groups. Rape committed by two men had never been studied or compared with gang rape up until now. Results of this survey show dynamic and demographic differences between these two groups of sexual delinquents.

    In order to meet increasing demand, Hydro-Quebec will develop seven hydro power sites on the Manicouagan and Outardes Rivers to generate a total of 5,700 MW and an additional 30 billion kWh by 1973. On August 22, 1962, it was decided that the power would be transmitted over a 650-km network, using three 735-kV lines and six stations. The wet switching surge withstand level was set at 1,350 kV, based on the results obtained with a transient network analyser. The main 735-kV equipment was purchased from several manufacturers to insure prompt delivery and continuity of service. On September 21st, 1965, the Manicouagan-Levis section of the first line was energized at 735 kV, transmitting 300 MW. A month later, the second section of the line was energized and the power generated at the Manicouagan 2 plant was thus transmitted to Montreal. So far, only two pieces of equipment have shown signs of failure without causing, however, any serious shutdown. Results of tests carried out show that operation of a 735-kV network is safe and economical.

  15. Growing Physics and Astronomy Public Outreach in Montreal

    Simard, Gabrielle; Lepo, Kelly

    2017-01-01

    AstroMcGill was founded in 2011 by an enthusiastic group of undergraduate students, graduate students and post-doctoral fellows. It serves as the education and public outreach (EPO) branch of the astronomy group within the Physics Department at McGill University in Montreal, Quebec. Over the last five years, AstroMcGill has grown from organizing sporadic visits in a couple primary schools to running a successful inquiry-based outreach programme for grade 4-6 students, the McGill Space Explorers. During the same time span, the attendance at public AstroNight lectures ramped up from attracting a few dozen people to over 500 people each month. We will highlight the recent successes of the programme and our best guesses for the reasons behind this success. We will also discuss the challenges of working in a bilingual city as we juggle our majority anglophone volunteers, a mandatory french science curriculum for primary school children and the (somewhat) overlapping English- and French-speaking communities in the city.

    Kirchhoff, J.; Stasch, W.P.

    1998-10-01

    Prior to release from the radiological supervision and control regime of the AtG (German Atomic Energy Act), nuclear facilities have to be scanned using licensed radioactivity measuring methods for providing evidence that the remaining radioactive contamination is below the legally defined limits and excludes hazards to the population, material goods, or the environment. The manually performed {alpha}/{beta} measuring methods applied so far for radiological decontrolling measurement are surface scanning methods measuring the contamination of very thin surface layers of the structures, while radioactivity in deeper layers is not necessarily detected. The gamma scanning method presented in this document is capable of scanning the structures and materials of nuclear facilities from the surface down to much deeper layers in just one measuring run. The automated scanning process at the same time offers the advantage of preventing the uncertainties possibly contributed through human factors. (orig./CB) [Deutsch] Vor der Entlassung von kerntechnischen Anlagen aus dem Geltungsbereich des AtG ist sicherzustellen, dass von der Anlage nach Freigabe aus der atomrechtlichen Ueberwachung keine Gefahren fuer Personen, Sachgueter und die Umwelt ausgehen koennen. Hierzu sind die Anlagen freizumessen, d.h. es ist durch qualifizierte Messverfahren sicherzustellen, dass festgelegte radiologische Grenzwerte unterschritten werden. Die bisherigen auf {alpha}/{beta}-Messung beruhenden Freimessverfahren (Kontaminationsmonitore) erfassen nur die Radioaktivitaet in duennsten Oberflaechenschichten. Radioaktivitaet in darunter liegenden Schichten wird nicht zwangslaeufig erfasst. Zudem erfolgen diese Messungen ausschliesslich manuell. Das Gamma-Scanning-Freimessverfahren erfasst neben der Oberflaechenschicht gleichzeitig auch tiefere Schichten. Der Nachweis der Grenzwertunterschreitung kann somit in nur einem Arbeitsgang erbracht werden. Durch automatisiertes Scannen koennte darueber hinaus

    Hypocalcemia following thyroidectomy often prolongs hospital stay and is potentially life-threatening. The objective of this study is to determine whether the season when thyroidectomy is performed is associated with postoperative hypocalcemia. Retrospective case series of patients undergoing thyroid surgery from 2009 to 2015. Tertiary care academic institution in Montreal, Canada. A consecutive sample of 823 patients undergoing thyroidectomy by a single high-volume otolaryngologist for a suspected or confirmed thyroid malignancy. Patient demographics, procedure type, calcium and vitamin D supplementation, and seasonal rate of hypocalcemia postthyroidectomy were calculated and compared. Average seasonal rates of postthyroidectomy hypocalcemia in the winter, spring, summer, and autumn were, respectively, 8.3% (8 of 216), 7.3% (12 of 165), 1.5% (3 of 201), and 3.5% (8 of 228; P operated in the winter were 5.6 times more likely to develop hypocalcemia as compared with those in the summer (P factoring in season when surgery was performed, procedure type, and preoperative vitamin D/calcium supplementation, surgery occurring in the winter predicted a hypocalcemia event (correlation coefficient [SE]: 0.72 [0.024], P = .026; 0.006 [0.025], P = .81; 0.004 [0.019], P = .82, respectively). In this study, patients undergoing thyroidectomy in the winter months were more likely to develop postoperative hypocalcemia when compared with those operated in the summer.

  18. Climate change impacts on pollinic productivity and allergic rhinitis in Montreal between 1994 and 2002

    Garneau, M.; Breton, M.; Fortier, I. [Quebec Univ., Montreal, PQ (Canada)

    2005-07-01

    This presentation defined the correlation between pollinic concentrations of ragweed and medical consultations for allergic rhinitis in Montreal between 1994 and 2002, taking into account meteorological variables and socio-economic factors. The spatio-temporal dynamic of pollinic, meteorological, socio-economic and epidemiological values was reconstituted from descriptive, geographical and statistical analyses. Throughout the ragweed pollinic seasons (August to October) between 1994 and 2002 in the Montreal island area, there were 7,138 consultations for allergic rhinitis. The study concluded that the lengthening of the pollinic seasons, as well as the increase in the average number of medical consultations, combined with the significant correlation linking the temperature to pollinic concentrations suggests that the population affected by pollen allergies will increase over the coming decades in Montreal, and that it will affect certain areas more than others, which is consistent with the anticipated impacts of the rise in temperatures forecasted by different models of climate scenarios.

  19. SUSTAINABILITY ASSESSMENT IN URBAN PLANNING. A CHALLENGE FOR A METHODOLOGICAL CONSTRUCTION: MONTREAL AS CASE STUDY

    María de Lourdes Flores Lucero

    2014-09-01

    Full Text Available In this paper we describe the methodological process for the qualitative evaluation of the concept of sustainability and its application in the island of Montreal. At the same time we present our theoretical approach and the main results issued of the assessment. We take as analytical tools the Montreal Urban Plan of 2004 and the Strategic Plan for Sustainable Development 2005. We conclude with two main points, first, that the theoretical and pragmatic aspects of urban sustainability in Montreal have been treated in an organic, complex, dynamic and flexible way, allowing social participation and the inclusion of the values of all stakeholders, which are both key elements to follow the path towards sustainability; and secondly, that the approach to an object with such features requires the construction of complex, organic and methodological processes.

    Full Text Available Assessing the impact of the highway 25 expansion project on air quality in montreal using gis. The aim of the paper is to assess local air pollution implications of the Highway 25 expansion project from Montreal. The basic concept of the roadway air dispersion model consists in calculating air pollutant levels in the vicinity of a highway by considering it as a line source. To fulfill this assessment, GIS software was used in order to determine pollutant distribution around the study area based on data collected by existing air monitoring stations located in the City of Montreal. GIS interpolation methods, notably Kriging and Inverse Distance Weighted (IDW, was used to generate maps of pollutant concentrations across the study area. From the results, recommendations will be made in regards to the project and appropriate mitigatory alternatives suggested.

    The Montreal Cognitive Assessment is a brief and easy screening tool for accurately testing cognitive dysfunction in Parkinson's disease. We tested its validity for use in non-English (Malayalam) speaking patients with Parkinson's disease. We developed a Malayalam (a south-Indian language) version of Montreal Cognitive Assessment and applied to 70 patients with Parkinson's disease and 60 age- and education-matched healthy controls. Metric properties were assessed, and the scores were compared with the performance in validated Malayalam versions of Mini Mental Status Examination and Addenbrooke's Cognitive Examination. The Montreal Cognitive Assessment-Malayalam showed good internal consistency and test-retest reliability and its scores correlated with Mini Mental Status Examination (patients: R = 0.70; P speaking Parkinson's disease patients for early screening and potential future interventions for cognitive dysfunction.

  2. Seismic Vulnerability Assessment for Montreal -An Application of HAZUS-MH4

    Yu, Keyan

    2011-12-01

    Seismic loss estimation for Montreal, Canada is performed for a 2% in 50 years seismic hazard using the HAZUS-MH4 tool developed by US Federal Emergency Management. The software is manipulated to accept a Canadian setting for the Montreal study region, which includes 522 census tracts. The accuracy of loss estimations using HAZUS is dependent on the quality and quantity of data collection and preparation. The data collected for Montreal study region comprise: (1) the building inventory (2) hazard maps regarding soil amplification, liquefaction, and landslides (3) population distribution at three different times of the day (4) census demographic information and (5) synthetic ground motion contour maps using three different ground motion prediction equations. All these data are prepared and assembled into geodatabases that are compatible with the HAZUS software. The study estimated that roughly 5% of the building stock would be damaged with direct economic losses evaluated at 1.4 billion dollars for a scenario corresponding to the 2% in 50 years scenario. The maximum number of casualties associated with this scenario corresponds to a time of occurrence of 2pm and would result in approximately 500 people being injured. Epistemic uncertainty was considered by obtaining damage estimates for three attenuation functions that were developed for Eastern North America. The results indicate that loss estimates are highly sensitive to the choice of the attenuation function and suggests that epistemic uncertainty should be considered both for the definition of the hazard function and in loss estimation methodologies. The next steps in the study should be to increase the size of the survey area to the Greater Montreal which includes more than 3 million inhabitants and to perform more targeted studies for critical areas such as downtown Montreal, and the south-eastern tip of Montreal. The current study was performed mainly for the built environment; the next phase will need to

  3. The Montreal Protocol treaty and its illuminating history of science-policy decision-making

    Grady, C.

    2017-12-01

    The Montreal Protocol on Substances that Deplete the Ozone Layer, hailed as one of the most effective environmental treaties of all time, has a thirty year history of science-policy decision-making. The partnership between Parties to the Montreal Protocol and its technical assessment panels serve as a basis for understanding successes and evaluating stumbles of global environmental decision-making. Real-world environmental treaty negotiations can be highly time-sensitive, politically motivated, and resource constrained thus scientists and policymakers alike are often unable to confront the uncertainties associated with the multitude of choices. The science-policy relationship built within the framework of the Montreal Protocol has helped constrain uncertainty and inform policy decisions but has also highlighted the limitations of the use of scientific understanding in political decision-making. This talk will describe the evolution of the scientist-policymaker relationship over the history of the Montreal Protocol. Examples will illustrate how the Montreal Protocol's technical panels inform decisions of the country governments and will characterize different approaches pursued by different countries with a particular focus on the recently adopted Kigali Amendment. In addition, this talk will take a deeper dive with an analysis of the historic technical panel assessments on estimating financial resources necessary to enable compliance to the Montreal Protocol compared to the political financial decisions made through the Protocol's Multilateral Fund replenishment negotiation process. Finally, this talk will describe the useful lessons and challenges from these interactions and how they may be applicable in other environmental management frameworks across multiple scales under changing climatic conditions.

  7. The Importance of the Montreal Protocol in Protecting the Earth's Hydroclimate

    Seager, R.; Wu, Y.; Polvani, L. M.

    2012-12-01

    The 1987 Montreal Protocol regulating emissions of ozone depleting chlorofluorocarbons (CFCs) was motivated primarily by the harm to human health and ecosystems arising from increased exposure to ultraviolet-B (UV-B) radiation associated with depletion from the ozone layer. It is now known that the Montreal Protocol has reduced global warming since CFCs are greenhouse gases (GHGs). In this paper we show that the Montreal Protocol also significantly protects the Earth's hydroclimate, even though this was also not a motivating factor in the decision-making that led to the Protocol. General Circulation Model (GCM) results show that in the coming decade (2020-29), under the 'World Avoided' scenario of no regulations on CFC emissions, the subtropical dry zones would in general get drier, and the middle and high latitude regions wetter. This change is similar, in both pattern and magnitude, to that in the coming decade caused by projected increases in carbon dioxide concentrations. This implies that because of the Montreal Protocol, and the ozone depletion and global warming associated with CFCs thus avoided, the hydrological cycle changes in the coming decade will be significantly less than what they otherwise would have been.

    2006-07-01

    Water management for the Mille Iles River, which supplies drinking water to 400,000 people, was discussed with reference to solutions for critically low water flow which was experienced in 2001 and 2002. The river is part of the Lac des Deux Montagnes watershed in the region of Montreal which is characterized as a high population growth area. In the summer of 2001, municipalities served by the Mille Iles River were faced with problems in the supply of drinking water when the river flow reached only 13 cubic metres per second. The minimal values of flow observed for this time of year have rarely been under 20 cubic metres per second since 1970. The quality of water was reduced under such conditions of flow because the dilution of wastewater discharged into the river became so weak that the aging water treatment facilities had to work beyond their capacity. Quebec's Center of Water Expertise (CEHQ) intervened in an emergency measure to ensure water quality. This study investigated the following 3 possible scenarios for a solution to this problem: (1) to increase the Mille Iles River capacity at the Lac des Deux Montagnes outlet, (2) to reduce the flow discharged by the 3 other outlets of Lac des Deux Montagnes, and (3) to increase the inflow to Lac des Deux Montagnes from reservoirs located in the Ottawa River watershed. The first solution was favoured. 2 refs., 1 tab., 8 figs.

    Water management for the Mille Iles River, which supplies drinking water to 400,000 people, was discussed with reference to solutions for critically low water flow which was experienced in 2001 and 2002. The river is part of the Lac des Deux Montagnes watershed in the region of Montreal which is characterized as a high population growth area. In the summer of 2001, municipalities served by the Mille Iles River were faced with problems in the supply of drinking water when the river flow reached only 13 cubic metres per second. The minimal values of flow observed for this time of year have rarely been under 20 cubic metres per second since 1970. The quality of water was reduced under such conditions of flow because the dilution of wastewater discharged into the river became so weak that the aging water treatment facilities had to work beyond their capacity. Quebec's Center of Water Expertise (CEHQ) intervened in an emergency measure to ensure water quality. This study investigated the following 3 possible scenarios for a solution to this problem: (1) to increase the Mille Iles River capacity at the Lac des Deux Montagnes outlet, (2) to reduce the flow discharged by the 3 other outlets of Lac des Deux Montagnes, and (3) to increase the inflow to Lac des Deux Montagnes from reservoirs located in the Ottawa River watershed. The first solution was favoured. 2 refs., 1 tab., 8 figs.

    1997-06-01

    Full Text Available The intracarotid amobarbital procedure was carried out in 8 male and 7 female candidates to temporal lobectomy, and a female candidate to frontal lesionectomy, aged 18-50 (mean 32.5 years. Language and memory were tested after injection in each hemisphere. Both were measured by the Montreal procedure. In 9 patients language and memory were evaluated with the Seattle procedure too. In 12 patients the left hemisphere was dominant for language; three had bilateral dominance. In I patient the Seattle procedure demonstrated the dominant hemisphere by relatively slowness of speech during the drug effect in the left hemisphere. Memory was defined to be in the left hemisphere in 12 patients, in the right in 2, bilateral in 1 and in another lateralization was not possible. In 1 patient memory dominance was determined by the Montreal protocol alone because of lack of cooperation. These early results indicate that the methods may be complementary for determination of language and memory dominance in epilepsy surgery candidates.O testo do amobarbital intracarotídeo foi realizado em 8 homens e 7 mulheres candidatos a lobectomia temporal e em uma mulher candidata a lesionectomia frontal, com idades de 18-50 (média 32,5 anos.

  15. The precautionary principle as a provisional instrument in environmental policy: The Montreal Protocol case study

    Jacobs, J. Roger

    2014-01-01

    Highlights: • I examine whether a policy invoked under the Precautionary Principle can move beyond provisional status. • I review the certainty of conclusions based upon the Global Ozone Research and Monitoring Project. • There is high certainty that anthropogenic ozone depletion has health consequences in polar regions. • Current research focuses on long term projections of risk that perpetuates high uncertainty. • Establishment of a community to generate Assessments acts to perpetuate the period of uncertainty. - Abstract: Environmental studies identify possible threats to the health of the public or the environment when the scientific certainty of risk is low, but the potential cost is high. Governments may respond by invoking the Precautionary Principle, holding that scientific certainty is not required to take actions that reduce possible risk. EU guidelines suggest that precautionary measures remain provisional until sufficient scientific certainty is generated. Here I study the Scientific Assessments produced for the Montreal Protocol, and the scientific community that generates them, and ask whether a long-standing program of scientific investigation and monitoring can generate sufficient scientific certainty to move beyond dependence on the Precautionary Principle. When the Montreal Protocol was ratified, many scientists strongly suspected that anthropogenic substances like chlorofluorocarbons were depleting stratospheric ozone. Although the risk was uncertain, the perceived cost to public health of ozone depletion was high. A quarter century after formulating the Montreal Protocol, science can define the conditions for ozone depletion with great certainty, but uncertainty remains in determining the scale and distribution of the attributable increase in damaging ultra-violet (UV) radiation. Organisations, such as NASA, and scientists that contribute to the Scientific Assessments comprise the community in which the scientific consensus of risk is

  16. Economics of "essential use exemptions" for metered-dose inhalers under the Montreal Protocol.

    DeCanio, Stephen J; Norman, Catherine S

    2007-10-01

    The Montreal Protocol on Substances that Deplete the Ozone Layer has led to rapid reductions in the use of ozone-depleting substances worldwide. However, the Protocol provides for "essential use exemptions" (EUEs) if there are no "technically and economically feasible" alternatives. An application that might qualify as an "essential use" is CFC-powered medical metered-dose inhalers (MDIs) for the treatment of asthma and chronic obstructive pulmonary disease (COPD), and the US and other nations have applied for exemptions in this case. One concern is that exemptions are necessary to ensure access to medications for low-income uninsureds. We examine the consequences of granting or withholding such exemptions, and conclude that government policies and private-sector programs are available that make it economically feasible to phase out chlorofluorocarbons (CFCs) in this application, thereby furthering the global public health objectives of the Montreal Protocol without compromising the treatment of patients who currently receive medication by means of MDIs.

  17. Face-offs in reproductive immunology: the Montreal forum meeting report.

    Croy, B Anne; Baines, Malcolm G

    2004-10-01

    The combined 12th International Congress of Immunology (ICI) and the 4th Annual Conference of the Federation of Clinical Immunological Societies (FOCIS) was held in Montreal, Canada July 18-23, 2004 and attracted over 6000 immunologists and almost 4000 abstracts. The host society, the Canadian Society for Immunology (CSI) spent many years in preparation for this large meeting and encouraged its members to propose topics for symposia and mini-symposia and to sponsor satellite meetings. With sponsorship of CSI; the Canadian Institutes of Health Research; the University of Guelph, Guelph, ON; Queen's University, Kingston, ON; McGill University, Montreal, QU, Canada; and the American Society for Reproductive Immunology, a focused, highly successful, one day satellite meeting on human uterine immunology was held. The highlights of the presentations and discussions are reported.

  18. The impact of the petrochemical industry in the economic development framework of the Montreal region

    Danis, M.

    1992-01-01

    A brief overview of the petrochemical industry in Canada was presented. The industry, which employs approximately 100,000 Canadians, has an annual production estimated to be in excess of 20 billion dollars. Similarly, in the province of Quebec, the petrochemical industry makes a very significant contribution to the economy of the province, especially to that of the Montreal region. Recent initiatives and investments by the Canadian Government in the petrochemical sector were summarized. Among these, subsidies to Petromont to improve and modernize its plant facilities in Varennes, to Himont Canada, also of Varennes, to develop a new manufacturing process, to Gaz Metropolitain to establish a centre of gas technology, were highlighted. These and other government measures and initiatives provide a solid foundation for the petrochemical industry to continue to play a pre-eminent role in the economy of the Montreal region

  19. Computer mapping as an aid in air-pollution studies: Montreal region study

    Granger, J M

    1972-01-01

    Through the use of computer-mapping programs, an operational technique has been designed which allows an almost-instant appraisal of the intensity of atmospheric pollution in an urban region on the basis of epiphytic sensitivity. The epiphytes considered are essentially lichens and mosses growing on trees. This study was applied to the Montreal region, with 349 samplings statiions distributed nearly uniformly. Computer graphics of the findings are included in the appendix.

  20. New Regional and Global HFC Projections and Effects of National Regulations and Montreal Protocol Amendment Proposals

    Velders, G. J. M.

    2015-12-01

    Hydrofluorocarbons (HFCs) are used as substitutes for ozone-depleting substances that are being phased out globally under Montreal Protocol regulations. New global scenarios of HFC emissions reach 4.0-5.3 GtCO2-eq yr-1 in 2050, which corresponds to a projected growth from 2015 to 2050 which is 9% to 29% of that for CO2 over the same time period. New baseline scenarios are formulated for 10 HFC compounds, 11 geographic regions, and 13 use categories. These projections are the first to comprehensively assess production and consumption of individual HFCs in multiple use sectors and geographic regions with emission estimates constrained by atmospheric observations. In 2050, in percent of global HFC emissions, China (~30%), India and the rest of Asia (~25%), Middle East and northern Africa (~10%), and USA (~10%) are the principal source regions; and refrigeration and stationary air conditioning are the major use sectors. National regulations to limit HFC use have been adopted recently in the European Union, Japan and USA, and four proposals have been submitted in 2015 to amend the Montreal Protocol to substantially reduce growth in HFC use. Calculated baseline emissions are reduced by 90% in 2050 by implementing the North America Montreal Protocol amendment proposal. Global adoption of technologies required to meet national regulations would be sufficient to reduce 2050 baseline HFC consumption by more than 50% of that achieved with the North America proposal for most developed and developing countries. The new HFC scenarios and effects of national regulations and Montreal Protocol amendment proposals will be presented.

    Since public transit infrastructure affects road traffic volumes and influences transportation mode choice, which in turn impacts health, it is important to estimate the alteration of the health burden linked with transit policies. We quantified the variation in health benefits and burden between a business as usual (BAU) and a public transit (PT) scenarios in 2031 (with 8 and 19 new subway and train stations) for the greater Montreal region. Using mode choice and traffic assignment models, we predicted the transportation mode choice and traffic assignment on the road network. Subsequently, we estimated the distance travelled in each municipality by mode, the minutes spent in active transportation, as well as traffic emissions. Thereafter we estimated the health burden attributed to air pollution and road traumas and the gains associated with active transportation for both the BAU and PT scenarios. We predicted a slight decrease of overall trips and kilometers travelled by car as well as an increase of active transportation for the PT in 2031 vs the BAU. Our analysis shows that new infrastructure will reduce the overall burden of transportation by 2.5 DALYs per 100,000 persons. This decrease is caused by the reduction of road traumas occurring in the inner suburbs and central Montreal region as well as gains in active transportation in the inner suburbs. Based on the results of our study, transportation planned public transit projects for Montreal are unlikely to reduce drastically the burden of disease attributable to road vehicles and infrastructures in the Montreal region. The impact of the planned transportation infrastructures seems to be very low and localized mainly in the areas where new public transit stations are planned. Copyright © 2017 Elsevier Inc.

    Full Text Available El encuentro de cineastas de Argel (Argelia en diciembre de 1973 es bien conocido en los estudios sobre el cine del Tercer Mundo. En cuanto oportunidad de intercambio y discusión, este encuentro permitió la organización del trabajo de los cineastas y focalizó el debate en tres ejes principales: la contribución del cine a los procesos de liberación nacional, la descolonización de las pantallas del Tercer Mundo y la lucha contra la «alienación cultural». El resultado más importante fue la creación del Comité de Cine del Tercer Mundo. Solo seis meses más tarde, un nuevo encuentro tuvo lugar en Buenos Aires (Argentina. Por un lado, el presente ensayo muestra cómo un proyecto político-cinematográfico (el «tercermundismo» fue tomando forma gradualmente durante esos años y destaca el rol de ambas reuniones en la promoción de esta nueva identidad político-cultural. Por otro, este trabajo también propone la necesidad de incorporar a esta historia otro evento decisivo: los Rencontres Internationales pour un Nouveau Cinema, realizados en Montreal en 1974. Poco considerado incluso por la bibliografía especializada, este encuentro puede considerarse el más importante del cine polí- tico mundial de los años sesenta y setenta. Dada la cantidad y diversidad de los participantes de Europa, Estados Unidos, África y América Latina, la conferencia de Montreal fue crucial en la constitución del diálogo entre los cineastas políticos del Primer Mundo y la tendencia tercermundista construida entre Argel y Buenos Aires.Palabras clave: Tercer Mundo, tercermundismo, Tercer Cine, Nuevo Cine Latinoamericano, Federación Panafricana de CineastasAbstract:The filmmakers meeting held in Algiers (Algeria in December 1973 is a wellknown event among Third World Cinema´s studies.

    Full Text Available Les mobilités pendulaires semblent être en augmentation en Europe depuis une dizaine d’années. Cette croissance du temps passé à se déplacer amène à remettre en question la conjecture de Zahavi et apparaît relativement inexplicable en regard du paradigme classique de l’acteur rationnel traditionnellement utilisé dans le champ des transports. Si, dans la littérature, les temps de déplacements sont principalement expliqués par le contexte résidentiel, la forme urbaine et le travail, ce cadre explicatif ne dit rien des processus de décision eux-mêmes qui amènent aux pendularités intensives.À partir d’une enquête qualitative menée auprès de pendulaires français, suisses et belges, cette contribution propose d’analyser les arbitrages et les éléments déterminants des processus de la grande pendularité. Les mobilités quotidiennes pendulaires apparaissent comme le résultat de compromis entre activité professionnelle, attachement résidentiel et choix de vie et prennent ainsi la forme de stratégies de conciliation entre vie privée et vie professionnelle. Ces mobilités spatiales permettent alors paradoxalement la préservation des ancrages résidentiels, sociaux et familiaux.Roots and wings.

These raising mobility patterns lead to reappraise the Zahavi conjecture and appear largely inexplicable by the classical rational actor paradigm traditionally used in transportation research. In literature, commuting is mainly explained by residential contexts, urban forms and job. Nevertheless this theoretical frame says little about the decision-making processes themselves. Based on a qualitative survey conducted in three European countries - France, Belgium and Switzerland – among a population of high commuters, this paper proposes an analysis of

  8. Nerves and Nostalgia: Expression of Loss Among Greek Immigrants in Montreal

    Lock, Margaret; Wakewich-Dunk, Pamela

    1990-01-01

    The authors interviewed first-generation Greek immigrant women in Montreal about nonspecific somatic symptoms. The concept of nevra (nerves), which was central to these discussions, was used to link environmental and psychosocial variables with distress and painful physical states. The authors discuss the cultural construction of female identity in Greece and analyze the negative effect of immigration on self-esteem, often manifested as attacks of nevra. Metaphorical concepts, such as nevra, can be used to improve physician understanding and to facilitate communication with, and enhance care of, immigrant patients. PMID:21234036

  11. Modeling climate effects on hip fracture rate by the multivariate GARCH model in Montreal region, Canada

    2014-07-01

    Changes in extreme meteorological variables and the demographic shift towards an older population have made it important to investigate the association of climate variables and hip fracture by advanced methods in order to determine the climate variables that most affect hip fracture incidence. The nonlinear autoregressive moving average with exogenous variable-generalized autoregressive conditional heteroscedasticity (ARMA X-GARCH) and multivariate GARCH (MGARCH) time series approaches were applied to investigate the nonlinear association between hip fracture rate in female and male patients aged 40-74 and 75+ years and climate variables in the period of 1993-2004, in Montreal, Canada. The models describe 50-56 % of daily variation in hip fracture rate and identify snow depth, air temperature, day length and air pressure as the influencing variables on the time-varying mean and variance of the hip fracture rate. The conditional covariance between climate variables and hip fracture rate is increasing exponentially, showing that the effect of climate variables on hip fracture rate is most acute when rates are high and climate conditions are at their worst. In Montreal, climate variables, particularly snow depth and air temperature, appear to be important predictors of hip fracture incidence. The association of climate variables and hip fracture does not seem to change linearly with time, but increases exponentially under harsh climate conditions. The results of this study can be used to provide an adaptive climate-related public health program and ti guide allocation of services for avoiding hip fracture risk.

  12. Solar water heating at Ikea's Montreal store; Chauffage solaire de l'eau courante au magasin Ikea de Montreal

    Lagana, A.; Sonmor, K. [Ecovision experts-conseils inc., Montreal, PQ (Canada)

    2010-01-01

    The Ikea store in Montreal has integrated an energy efficient solar water heater into its building infrastructure. In June 2010, 30 fixed solar panels were installed on the roof to recuperate energy from the sun for hot water use in the restaurant and store facilities. Prior to this installation, the store was using natural gas for water heating purposes. During a sunny summer day, the solar water heater can provide 100 percent of the hot water needs of the store, even though it was designed to provide only one-third of the heating requirements. The panels are made of copper and painted with black titanium paint. A solution of water and antifreeze circulates in the panels. Digital controls are used at the pumps to control the temperature. The Ikea store uses approximately 3,100 gallons of water per day. The panels provide more than 60 MWh of energy, and represent a savings of 8440 cubic metres of natural gas, and a savings of 19.7 tons of carbon dioxide. The panels cost $1,300 and the return on investment is estimated to be 15.6 years. 3 figs.

    Mary Ellen Jeans

    2000-01-01

    Full Text Available This paper chronicles the development of the Montreal General Hospital Pain Centre from its inception in 1974 to the present. Highlighted in particular are the contributions of Ronald Melzack to this history. Data for the article arose, in the main, from an interview with Dr Melzack carried out earlier in the year. Discussions with former and present members of the pain centre team, including former graduate students, provided additional information. The article begins with a recounting of those individuals and events that inspired Ron early in his 'pain career' to pursue his dream of a multidisciplinary pain centre, the first of its kind in Canada. The forces that helped shape the development of this centre and the challenges that had to be overcome are described.

  19. Selecting corporate political tactics: The Montreal Protocol on substances that deplete the ozone layer

    Getz, K.A.

    1991-01-01

    This study examines factors influencing the choice of one set of tactics over others. The case of ozone depletion is used as the research context, and the data are drawn from US companies having a stake in this issue. A model is developed which suggests that a firm's choice of political tactics (dependent variable) is dependent on the targets of political activity and the nature of the issue of concern (independent variables), and a variety of organizational and industry factors (moderating variables). The paradigm of agency is used to systematically assess the relative importance of these factors. To test the relevance of the model, an empirical study was done. The case of the Montreal protocol on Substances That Deplete the Ozone Layer was chosen as a setting; and 551 firms directly affected by policy intended to protect the ozone layer were surveyed. There were 151 usable responses. Generally, the findings were consistent with the model

  20. Bank of Montreal v. Dynex Petroleum Ltd.: the priority of overriding royalties and net profit interests

    Dearlove, F.R.

    1996-01-01

    The practice by the petroleum industry of granting overriding royalties (ORRs) and net profit interests (NPIs), was discussed. Some of the reasons for granting ORRs or NPIs included: (1) securing a lease, (2) obtaining geological information, (3) a condition of employment, or (4) acceptance of risk in exploration. In the recent case of Bank of Montreal versus Dynex Petroleum Ltd., it was held that in Alberta, ORRs and NPIs issuing out of a lessee's interest in an oil and gas lease cannot be a grant of interest in land. The effect of this decision is that it will make it difficult to create an ORR or NPI that is not merely a contract. An appeal is expected

    To verify age and education effects on communication performance of healthy adults in the Montreal Communication Evaluation Battery, Portuguese version (MAC-PT). The sample comprised 90 healthy adults from Portugal, European Portuguese speakers, divided into nine groups according to educational level (4-9, 10-13, and > 13 years of formal schooling) and age (19-40, 41-64, and 65-80 years). The influence of age and education was assessed by comparing mean scores between groups, using a two-way analysis of variance followed by Bonferroni post hoc tests (p ≤ 0.05). The results showed that participants' performance was influenced by age in pragmatic-inferential, discursive, and prosodic tasks. Education had the greatest influence on the performance in all processes evaluated by the MAC-PT. Age and education seem to influence the communicative performance and should be considered in the assessment of neurological patients.

  2. Required internship in diagnostic radiology in the fifth year of medicine at Montreal University

    Saint-Georges, G.; Raymond-Tremblay, D.; Danais, S.; Dussault, R.; Grignon, A.; Lafortune, M.; Saltiel, J.

    1984-01-01

    Problems of methodology, organization, and evaluation confronting the radiology departments of the university hospitals affiliated with the University of Montreal, the medical students, and the University itself in connection with an elective internship in radiology offered in the fifth year of medicine, resulted in the formation of a committee to reorganize the course of study. In this concise article the authors describe this and other measures taken by the University to solve these problems. The committees' main purpose was to restructure the internship which was made compulsory so that future physicians would be prepared to draw on the resources of diagnostic radiology and nuclear medicine. To this end, the committee formulated the objectives, content, evaluation system, and pedagogical methods to be used in those courses. The 25 self-teaching modules, together with the observation and practical interpretation of radiology sessions, proved highly useful in solving the initial problems, and were of particular interest to the students.

    2016-07-01

    The aim of this study was to assess certain musical abilities in 30 patients with Alzheimer's disease (AD) and 30 healthy controls by using the complete version of the Montreal Battery of Evaluation of Amusia (MBEA). This battery evaluates melodic (scale, contour, and interval) and temporal (rhythm and meter) perception of music and musical memory. We found that altered musical processing is a common feature in AD. Despite that, AD subjects show partially spared abilities for temporal organization of music, though not for melodic perception and musical memory. This peculiar dysfunctional pattern could depend on the neurodegenerative involvement of some specific areas for music perception and memory in the brains of AD patients. Further studies are needed to investigate the usefulness of additional musical tests like the MBEA on larger samples to confirm our preliminary data. © 2016 New York Academy of Sciences.

Candidate École nationale d'administration publique Julie-Maude Normandin Ph.D. Candidate École nationale d'administration publique Marie-Christine Therrien Professor École nationale d'administration publique The proposed paper presents preliminary results on the resilience of organizations managing critical infrastructure in the Metropolitan Montreal area (Canada). A resilient city is characterized by a network of infrastructures and individuals capable of maintaining their activities in spite of a disturbance (Godschalk, 2002). Critical infrastructures provide essential services for the functioning of society. In a crisis situation, the interruption or a decrease in performance of critical infrastructures could have important impacts on the population. They are also vulnerable to accidents and cascading effects because on their complexity and tight interdependence (Perrow, 1984). For these reasons, protection and security of the essential assets and networks are one of the objectives of organizations and governments. But prevention and recovery are two endpoints of a continuum which include also intermediate concerns: ensuring organizational robustness or failing with elegance rather than catastrophically. This continuum also includes organizational resilience (or system), or the ability to recover quickly after an interruption has occurred. Wildavsky (1988) proposes that anticipation strategies work better against known problems while resilience strategies focus on unknown problems. Anticipation policies can unnecessarily immobilize investments against risks, while resilience strategies include the potential for a certain sacrifice in the interests of a more long-term survival and adaptation to changing threats. In addition, a too large confidence in anticipation strategies can bring loss of capacity of an

  5. Soundscape studies in Montreal's Biodome: using enclosed ecosystems to explain biodiversity to the public

    Fisher Favret, K. E.

    2016-02-01

    The Biodome in Montreal is a unique public museum with over 750 species organized into five different ecosystems. We spent several weeks obtaining soundscapes from three of these: Gulf of St. Lawrence, Labrador Coast, and Sub-Antarctic Islands. The idea was to leverage the accessibility and known biodiversity of these mesocosms to calibrate instruments, evaluate methods for assessing biodiversity, and educate people ranging from the penguin keeper to the general public about soundscape ecology and biodiversity assessments. The Gulf of St. Lawrence exhibit has hundreds of fish that belong to 20 species swimming in 2.5 million gallons of seawater, with seabirds and invertebrates nearby. The Sub-Antarctic Islands exhibit, by contrast, has four species of penguins. As part of Montreal's Space for Life program, there is a searchable index of the species available to the public: http://espacepourlavie.ca/en/fauna-and-flora-biodome.The emerging field of soundscape ecology offers a new approach for effectively monitoring changes in sounds generated by communities ranging from urban centers to oceans. The entropy-based approach pioneered by Sueur et al., (2008) characterizes acoustic spectrograms based on the spectral space-filling properties of the sound producers. By calculating the complexity of the acoustic environment, we can detect cycles over various time scales. Disturbed systems can be detected by changes in the timing and frequency of sounds filling various "niches" in the soundscape that might act as early warnings of changes induced on scales from single events to climate shifts. These changes range from presence or absence of vocalizations by individual species, to changes in the higher order statistics of the daily sound structures that include sounds with physical, biological, and human origins. Here we show what we have learned so far about comparing enclosed ecosystems to the real world outside, and some of the challenges and rewards of using soundscape

  6. Evaluation of air quality in arenas on the Island of Montreal : winter 2006-2007

    Price, K.; Beausoleil, M.; Lefebvre, L.

    2007-03-01

    For the past twenty years, cases of nitrogen dioxide (NO 2 ) and carbon monoxide (CO) poisoning have been reported in arenas in Quebec. A 1997 evaluation of air quality in 332 arenas in 9 different countries revealed that 40 per cent of arenas worldwide have high concentration of NO 2 . In Quebec, an air quality review at arenas in Montreal drew similar conclusions, that 69 per cent of the arenas have high concentrations of CO and/or NO 2 . In 1997, Quebec's environmental health committee established criteria of 20 ppm for CO, and 0.5 ppm for NO 2 in arenas, in order to ensure that athletes and the public at large do not suffer negative effects related to the presence of combustible gases. This information was distributed to the administrative personnel in arenas in Quebec by means of an awareness and information campaign. Since then, the number of arenas that have met these criteria for air quality in arenas in Montreal has climbed from 31 per cent in 1997 to 83 per cent in 2004. The practices put into action by arena administrators include: 1) regular maintenance of ice surface cleaning machines and other equipment that use fuel, 2) judicious use of ventilation so that gases can be evacuated from the premises, and, 3) periodic measurements of CO and NO 2 during peak usage times such as tournaments. Other means of lowering gas emissions have also shown to be helpful, such as replacement of ice surface cleaning machines with electrical ones, installation of CO and NO 2 detectors close to the rink surface so that ventilation machines could be activated, and the measurement and constant registration of these gases. It was concluded that these measures could help maintain good air quality in arenas. 15 refs., 1 tabs., 1 fig

  7. Control and monitoring of landfill gas underground migration at the City of Montreal sanitary landfill site

    Heroux, M.; Turcotte, L.

    1997-01-01

    The proposed paper covers the various aspects of control and monitoring of potential landfill gas (LFG) migration through soil voids or rock fractures at the City of Montreal sanitary landfill site. It depicts the social, geographical and geological context and presents a brief history of the landfill site. It describes the LFG collecting system and LFG migration monitoring equipment and programs. Finally it presents monitoring data taken over last few years. The landfill site is located in a well populated urban area. Since 1968, about 33 million metric tons of domestic and commercial waste have been buried in a former limestone quarry. Because of houses and buildings in the vicinity, 100 m in some locations, LFG underground migration is a major risk. LFG could indeed infiltrate buildings and reach explosive concentrations. So it must be controlled. The City of Montreal acquired the site in 1988 and has progressively built a LFG collecting system, composed of more than 288 vertical wells, to pump out of the landfill 280 million m 3 of gas annually. To verify the efficiency of this system to minimize LFG underground migration, monitoring equipment and programs have also been designed and put into operation. The monitoring network, located all around the landfill area, is composed of 21 well nests automated to monitor presence of gas in the ground in real time. In addition, 55 individual wells, where manual measurements are made, are also available. To complete the monitoring program, some measurements are also taken in buildings, houses and underground utilities in the neighborhood of the site. Monitoring data show that LFG underground migration is well controlled. They also indicate significant decrease of migration over the years corresponding to improvements to the LFG collecting system

  18. Montreal Cognitive Assessment (MoCA): validation study for frontotemporal dementia.

    Freitas, Sandra; Simões, Mário R; Alves, Lara; Duro, Diana; Santana, Isabel

    2012-09-01

    The Montreal Cognitive Assessment (MoCA) is a brief instrument developed for the screening of milder forms of cognitive impairment, having surpassed the well-known limitations of the Mini-Mental State Examination (MMSE). The aim of the present study was to validate the MoCA as a cognitive screening test for behavioral-variant frontotemporal dementia (bv-FTD) by examining its psychometric properties and diagnostic accuracy. Three matched subgroups of participants were considered: bv-FTD (n = 50), Alzheimer disease (n = 50), and a control group of healthy adults (n = 50). Compared with the MMSE, the MoCA demonstrated consistently superior psychometric properties and discriminant capacity, providing comprehensive information about the patients' cognitive profiles. The diagnostic accuracy of MoCA for bv-FTD was extremely high (area under the curve AUC [MoCA] = 0.934, 95% confidence interval [CI] = 0.866-.974; AUC [MMSE] = 0.772, 95% CI = 0.677-0.850). With a cutoff below 17 points, the MoCA results for sensitivity, specificity, positive predictive value, negative predictive value, and classification accuracy were significantly superior to those of the MMSE. The MoCA is a sensitive and accurate instrument for screening the patients with bv-FTD and represents a better option than the MMSE.

  19. Cross-Cultural Applicability of the Montreal Cognitive Assessment (MoCA): A Systematic Review.

    O'Driscoll, Ciarán; Shaikh, Madiha

    2017-01-01

    The Montreal Cognitive Assessment (MoCA) is widely used to screen for mild cognitive impairment (MCI). While there are many available versions, the cross-cultural validity of the assessment has not been explored sufficiently. We aimed to interrogate the validity of the MoCA in a cross-cultural context: in differentiating MCI from normal controls (NC); and identifying cut-offs and adjustments for age and education where possible. This review sourced a wide range of studies including case-control studies. In addition, we report findings for differentiating dementias from NC and MCI from dementias, however, these were not considered to be an appropriate use of the MoCA. The subject of the review assumes heterogeneity and therefore meta-analyses was not conducted. Quality ratings, forest plots of validated studies (sensitivity and specificity) with covariates (suggested cut-offs, age, education and country), and summary receiver operating characteristic curve are presented. The results showed a wide range in suggested cutoffs for MCI cross-culturally, with variability in levels of sensitivity and specificity ranging from low to high. Poor methodological rigor appears to have affected reported accuracy and validity of the MoCA. The review highlights the necessity for cross-cultural considerations when using the MoCA, and recognizing it as a screen and not a diagnostic tool. Appropriate cutoffs and point adjustments for education are suggested.

  20. Sociology in Global Environmental Governance? Neoliberalism, Protectionism and the Methyl Bromide Controversy in the Montreal Protocol

    Brian J. Gareau

    2017-10-01

    Full Text Available Sociological studies of global agriculture need to pay close attention to the protectionist aspects of neoliberalism at the global scale of environmental governance. With agri-food studies in the social sciences broadening interrogations of the impact of neoliberalism on agri-food systems and their alternatives, investigating global environmental governance (GEG will help reveal its impacts on the global environment, global science/knowledge, and the potential emergence of ecologically sensible alternatives. It is argued here that as agri-food studies of neoliberalism sharpen the focus on these dimensions the widespread consequences of protectionism of US agri-industry in GEG will become better understood, and the solutions more readily identifiable. This paper illustrates how the delayed phase out of the toxic substance methyl bromide in the Montreal Protocol exemplifies the degree to which the US agri-industry may be protected at the global scale of environmental governance, thus prolonging the transition to ozone-friendly alternatives. Additionally, it is clear that protectionism has had a significant impact on the dissemination and interpretation of science/knowledge of methyl bromide and its alternatives. Revealing the role that protectionism plays more broadly in the agriculture/environmental governance interface, and its oftentimes negative impacts on science and potential alternatives, can shed light on how protectionism can be made to serve ends that are at odds with environmental protection.

  1. Milrinone and homeostasis to treat cerebral vasospasm associated with subarachnoid hemorrhage: the Montreal Neurological Hospital protocol.

    Lannes, Marcelo; Teitelbaum, Jeanne; del Pilar Cortés, Maria; Cardoso, Mauro; Angle, Mark

    2012-06-01

    For the treatment of cerebral vasospasm, current therapies have focused on increasing blood flow through blood pressure augmentation, hypervolemia, the use of intra-arterial vasodilators, and angioplasty of proximal cerebral vessels. Through a large case series, we present our experience of treating cerebral vasospasm with a protocol based on maintenance of homeostasis (correction of electrolyte and glucose disturbances, prevention and treatment of hyperthermia, replacement of fluid losses), and the use of intravenous milrinone to improve microcirculation (the Montreal Neurological Hospital protocol). Our objective is to describe the use milrinone in our practice and the neurological outcomes associated with this approach. Large case series based on the review of all patients diagnosed with delayed ischemic neurologic deficits after aneurysmal subarachnoid hemorrhage between April 1999 and April 2006. 88 patients were followed for a mean time of 44.6 months. An intravenous milrinone infusion was used for a mean of 9.8 days without any significant side effects. No medical complications associated with this protocol were observed. There were five deaths; of the surviving patients, 48.9 % were able to go back to their previous baseline and 75 % had a good functional outcome (modified Rankin scale ≤ 2). A protocol using intravenous milrinone, and the maintenance of homeostasis is simple to use and requires less intensive monitoring and resources than the standard triple H therapy. Despite the obvious limitations of this study's design, we believe that it would be now appropriate to proceed with formal prospective studies of this protocol.

  2. Sustainability Assessment of the Residential Land Use in Seven Boroughs of the Island of Montreal, Canada

    Ricardo Enrique Vega-Azamar

    2015-02-01

    Full Text Available High resource utilization in the residential sector, and the associated environmental impacts, are central issues in the growth of urban regions. Land-use urban planning is a primary instrument for the proper development of cities; an important point is the consideration of the urban form’s influence on resource utilization intensity. Emergy synthesis, an energy-based methodological approach that allows the quantification and integration of both natural and human-generated flows interacting in urban environments, was used to assess sustainability of the residential land use of seven boroughs on the Island of Montreal. Natural resources, food, water, acquired goods and services, electricity and fuels were the main flows considered in the analysis. Results suggest that income, household size and distance to downtown are the variables affecting resource utilization intensity more noticeably and that allocation of green area coverage is an important parameter for controlling land use intensity. With the procedure used for calculating resource use intensity in the seven boroughs, it is possible to generate a tool to support urban planning decision-making for assessing sustainable development scenarios. Future research should consider urban green space potential for accommodating local waste treatment systems, acting as a greenhouse gas emissions sink and promoting human health.

  3. Setting the census household into its urban context: Visualizations from 19th-century Montreal

    Sherry Olson

    2017-04-01

    Full Text Available Background: Organized by household, North American census data promoted research into household composition, but discouraged research into connections between urban households. Yet these constitute "communications communities" that powerfully influence demographic decisions (Szreter 1996. Objective: How can we uncover relations between urban households? From spatial cues, can we infer social connections that generate constraints on or incentives for the formation of a household, its break-up, reconstitution, or relocation? Methods: For Montreal and its suburbs, 1881‒1901, we employ double geocoding and lot-level precision to explore a dozen types of relationships. Samples for experiment are drawn from a local historical geographic information system (HGIS that integrates tax roll and directory with census data. Results: 'Family' was socially embedded at three levels. Neighbouring of kin was strategic, and kinship was a factor in employment, enterprise, and property development as well as residential choices. In managing property, family networks operated with a horizon of four generations. Conclusions: Introduction of geographic coordinates offers a critical set of neglected cues to relationships between households, such as business partnerships, credit, or use of transit or telephone. In an urban HGIS, advantageous features are lot-level precision and facilities for coding and matching addresses to accommodate alternative levels of spatial aggregation. Contribution: Geocoding is shown to be a breakthrough innovation for exploring urban connectivity. Experiments with maps and networks as tools of visual thinking invite us to rethink the 'census family' at higher levels of relatedness.

  4. Evaluating Recall and Recognition Memory Using the Montreal Cognitive Assessment: Applicability for Alzheimer's and Huntington's Diseases.

    Van Liew, Charles; Santoro, Maya S; Goldstein, Jody; Gluhm, Shea; Gilbert, Paul E; Corey-Bloom, Jody

    2016-12-01

    We sought to investigate whether the Montreal Cognitive Assessment (MoCA) could provide a brief assessment of recall and recognition using Huntington disease (HD) and Alzheimer disease (AD) as disorders characterized by different memory deficits. This study included 80 participants with HD, 64 participants with AD, and 183 community-dwelling control participants. Random-effects hierarchical logistic regressions were performed to assess the relative performance of the normal control (NC), participants with HD, and participants with AD on verbal free recall, cued recall, and multiple-choice recognition on the MoCA. The NC participants performed significantly better than participants with AD at all the 3 levels of assessment. No difference existed between participants with HD and NC for cued recall, but NC participants performed significantly better than participants with HD on free recall and recognition. The participants with HD performed significantly better than participants with AD at all the 3 levels of assessment. The MoCA appears to be a valuable, brief cognitive assessment capable of identifying specific memory deficits consistent with known differences in memory profiles. © The Author(s) 2016.

  5. Broken English, broken bones? Mechanisms linking language proficiency and occupational health in a Montreal garment factory.

    Premji, Stéphanie; Messing, Karen; Lippel, Katherine

    2008-01-01

    Language barriers are often cited as a factor contributing to ethnic inequalities in occupational health; however, little information is available about the mechanisms at play. The authors describe the multiple ways in which language influences occupational health in a large garment factory employing many immigrants in Montreal. Between 2004 and 2006, individual, semi-structured interviews were conducted with 15 women and 10 men from 14 countries of birth. Interviews were conducted in French and English, Canada's official languages, as well as in non-official languages with the help of colleague-interpreters. Observation within the workplace was also carried out at various times during the project. The authors describe how proficiency in the official languages influences occupational health by affecting workers' ability to understand and communicate information, and supporting relationships that can affect work-related health. They also describe workers' strategies to address communication barriers and discuss the implications of these strategies from an occupational health standpoint. Along with the longer-term objectives of integrating immigrants into the linguistic majority and addressing structural conditions that can affect health, policies and practices need to be put in place to protect the health and well-being of those who face language barriers in the short term.

  6. Perceptions, Preferences, and Behavior Regarding Energy and Environmental Costs: The Case of Montreal Transport Users

    Nayer Daher

    2018-02-01

    Full Text Available Providing travel-related fuel and environmental information to transport users is becoming increasingly relevant. However, the impact of providing such information on users’ travel behavior is yet to be determined. This research examined the perceptions and preferences related to the fuel consumption costs, greenhouse gas (GHG social costs, and health-related air pollution costs, and the influence such information could have on travel behavior. Examining the case of Montreal transport users, the authors conducted a survey in which the respondents were asked general and stated preference questions. The respondents were found to be unaware of the energy and environmental footprints of their travel. Approximately 85% of the respondents were not able to estimate GHG social costs and health-related air pollution costs across different modes. The respondents generally overestimated these costs and they interestingly reported higher environmental costs for public transport (metro compared to cars. They also preferred to receive such information in monetary units, and they were more comfortable in receiving the information through mobile applications over other tools/means. The research also found that fuel and environmental information influence respondents’ travel decisions especially their route choices. Finally, the respondents would be willing to pay an average of 7 Canadian dollars/month in exchange for obtaining the information.

  7. Psychic centrality: reflections on two psychohistoriographic cultural therapy workshops in Montreal.

    Hickling, Frederick W; Guzder, Jaswant; Robertson-Hickling, Hilary; Snow, Stephen; Kirmayer, Laurence J

    2010-02-01

    The use of psychohistoriographic cultural therapy (PCT) developed in Jamaica is described in the context of two workshops in Montreal. PCT is a form of group intervention that seeks to elicit and clarify the "psychic centrality" of a group. Psychic centrality refers to a sense of psychological containment or organization of diverse individual points of view through creating a historical map of collective experience. In PCT, this collective map is constructed and techniques borrowed from creative arts therapies are used to develop a performance. This performance provides additional containment and fosters a group process that can contain collective conflicts. The performance can also be used to engage an audience, working to contain conflict while representing diverse perspectives within the group. Factors that may contribute to the effectiveness of PCT and those that may derail the process are identified through the systematic comparison of the two workshops. PCT was demonstrated to cross successfully from a Third to a First World culture, and established potential as a method to facilitate group conflict resolution and for the promotion of pluralistic civil societies.

  8. Montreal Cognitive Assessment and Mini-Mental State Examination reliable change indices in healthy older adults.

    Kopecek, Miloslav; Bezdicek, Ondrej; Sulc, Zdenek; Lukavsky, Jiri; Stepankova, Hana

    2017-08-01

    Cognitive tests are used repeatedly to assess the treatment response or progression of cognitive disorders. The Montreal Cognitive Assessment (MoCA) is a valid screening test for mild cognitive impairment. The aim of our study was to establish 90% reliable change indices (RCI) for the MoCA together with the Mini-Mental State Examination (MMSE) in cognitively healthy older adults. We analyzed 197 cognitively healthy and functional independent volunteers aged 60-94 years, who met strict inclusion criteria for four consecutive years. The RCI methods by Chelune and Hsu were used. For 1, 2, and 3 years, the 90% RCI for MoCA using Chelune's formula were -4 ≤, ≥4; -4 ≤, ≥4 and -5 ≤, ≥4 points, respectively, and -3 ≤, ≥3 for the MMSE each year. Ninety percent RCI for MoCA using Hsu's formula ranged from -6 to 0, respectively, and +3 to +8 dependent on the baseline MoCA. Our study demonstrated RCI for the MoCA and MMSE in a 3-year time period that can be used for the estimation of cognitive decline or improvement in clinical settings.

    2012-10-01

    Full Text Available Objective: The aim of our study is to examine cognitive performance after mild stroke via Mini Mental State Examination (MMSE and Montreal cognitive assessment scale (MoCA and to compare the results.Material and methods: We examined 54 patients with mild stroke (aged 52 to 72 (mean 63.17, SD 5.96; 34 males and 20 females and 54 controls, adjusted by age, sex and education level. All subjects were tested via MMSE (Bulgarian version and MoCa (Bulgarian version. Data was collected in the single step model at the 90th day after stroke incident for patients and at the day of obtaining informed consent for controls. Results: Patients have poorer performance on both MMSE and MoCa than controls. MoCa has comparatively good discriminative validity and sensitivity.Conclusions: Although MMSE is one of the classical screening tools for cognitive impairment widely used in Bulgaria, other screening tools should not be ignored. On the basis of our results, MoCa is also a good screening instrument, especially for poststroke cognitive impairment.

  10. El programa de prevención de Montreal: lecciones para Colombia

    Enrique Chaux

    2005-08-01

    Full Text Available The Montreal Prevention Program has demonstrated a mayor world success in prevention of delinquency and violence. The most aggressive students of second and third grade participated in an intervention that had two components. First, several activities were done to develop social abilities and competencies. These activities occurred in small groups with one or two aggressive boys and other prosocial kids. Second, the families of the aggressive boys were visited several times in a two year period in order to help them develop child rearing practices such as constructive management of conflicts and crisis, handling of rewards, and monitoring the child behavior. Assessment demonstrated that the program decreased the delinquent and aggressive behavior, and also some risk behaviors such as drug use, early sexual activities, gang membership and school dropout. Some of these effects are still measurable in adulthood, almost 15 years after participating in the program. The article presents a detailed analysis of this experience, and also eight lessons for Colombia, among them, that the prevention is rewarding, especially when done early in life.

  11. Emergy Evaluation of Dwelling Operation in Five Housing Units of Montreal Island, Canada

    Ricardo Enrique Vega-Azamar

    2017-04-01

    Full Text Available Sustainability of cities and the environmental implications of high resource utilization by the domestic sector are growing concerns related to urban regions. Well-informed urban planning decision-making is an essential tool to help in the task and, for that, an important point to consider is the influence of parameters like residential density and housing typology on the intensity of resource utilization. Emergy synthesis, a life-cycle energy analysis methodological approach that considers the interaction of natural and human-made flows, was used to evaluate the environmental support for dwelling operational stage in five typical present-day housing units on the island of Montreal. As expected, resource utilization, measured as total emergy used, was positively correlated to housing unit size both with respect to number of occupants and dwelling size. Results suggest that variables affecting notably the intensity of resource utilization are per household income and per dweller habitable space and, while a higher income increased per capita emergy in all cases, increasing space availability per resident did not result in a decrease of empower density after 50 m2/person. Future work should consider lower and higher densities and analyses at the scale of blocks, neighborhoods and urban planning zones.

  12. Effects of Montreal municipal sewage effluents on immune responses of juvenile female rainbow trout (Oncorhynchus mykiss)

    Salo, Harri M.; Hebert, Nancy; Dautremepuits, Claire; Cejka, Patrick; Cyr, Daniel G.; Fournier, Michel

    2007-01-01

    The objective of this study was to examine the immunotoxicity of treated Montreal sewage effluents on juvenile female rainbow trout (Oncorhynchus mykiss). A comprehensive panel of immunological assays was used to evaluate the effects of exposure for 1 and 4 weeks to 1, 3, 10 and 20% sewage effluent. Phagocytic ingestion of fluorescent latex beads by head kidney macrophages and granulocytes was suppressed following 1-week of exposure, with the highest exposure concentration being the most suppressive. Phagocytic activity returned to control levels after 4 weeks of exposure. The cytotoxic activity of head kidney derived non-specific cytotoxic cells was enhanced after a 1-week exposure, especially at the lowest exposure concentration, and returned to control levels after 4 weeks of exposure. In vitro lymphocyte proliferation in response to LPS and ConA activation was not affected following sewage effluent exposure, but nonactivated, spontaneous proliferation of lymphocytes was suppressed in a dose-dependent manner after 4 weeks of exposure. Plasma lysozyme activity was elevated at lowest exposure concentration after 4 weeks. No changes were noted in either the blood leukocyte/erythrocyte ratio or in the proportion of circulating lymphocytes and thrombocytes. The proportion of circulating granulocytes increased following exposure for 4 weeks to the low effluent concentration. Plasma cortisol levels were not affected by effluent exposure suggesting that mechanisms other than stress influenced the observed immunomodulation. In summary, this study demonstrates that sewage effluent can alter the immune functions of rainbow trout

    The objective of this study was to examine the immunotoxicity of treated Montreal sewage effluents on juvenile female rainbow trout (Oncorhynchus mykiss). A comprehensive panel of immunological assays was used to evaluate the effects of exposure for 1 and 4 weeks to 1, 3, 10 and 20% sewage effluent. Phagocytic ingestion of fluorescent latex beads by head kidney macrophages and granulocytes was suppressed following 1-week of exposure, with the highest exposure concentration being the most suppressive. Phagocytic activity returned to control levels after 4 weeks of exposure. The cytotoxic activity of head kidney derived non-specific cytotoxic cells was enhanced after a 1-week exposure, especially at the lowest exposure concentration, and returned to control levels after 4 weeks of exposure. In vitro lymphocyte proliferation in response to LPS and ConA activation was not affected following sewage effluent exposure, but nonactivated, spontaneous proliferation of lymphocytes was suppressed in a dose-dependent manner after 4 weeks of exposure. Plasma lysozyme activity was elevated at lowest exposure concentration after 4 weeks. No changes were noted in either the blood leukocyte/erythrocyte ratio or in the proportion of circulating lymphocytes and thrombocytes. The proportion of circulating granulocytes increased following exposure for 4 weeks to the low effluent concentration. Plasma cortisol levels were not affected by effluent exposure suggesting that mechanisms other than stress influenced the observed immunomodulation. In summary, this study demonstrates that sewage effluent can alter the immune functions of rainbow trout.

  14. Montreal Protocol meeting looks to speed up phaseout of ozone depleters

    Rotman, D.; Chynoweth, E.

    1992-01-01

    Delegates from around the world are meeting in Copenhagen this week to debate an accelerated phaseout of chlorofluorocarbons (CFCs), a time schedule for the eventual phaseout of hydrochlorofluorocarbons (HCFCs), and phaseouts of methyl chloroform and carbon tetrachloride. The fate of methyl bromide will also be a hot issue. The fourth meeting of the parties to the Montreal Protocol is widely expected to put through a 100% CFC phaseout by Jan. 1, 1996, coming into agreement with current US and European Community rules. But debate continues over the intermediate phaseout schedule, with European members pushing for an 85% reduction - from a 1986 baseline - by Jan. 1, 1994, and others arguing for a 70% cut by 1994. Delegates are expected to agree to the final phaseout of halons on Jan. 1, 1996, with an 85% cut in carbon tet by 1995. The meeting is also expected to broadly agree on a Jan. 1, 1996 phaseout of methyl chloroform, with a 50% reduction from a 1989 baseline by Jan. 1, 1994. A critical debate for chemical producers will be on the fate of methyl bromide. Many observers expect some phaseout for the chemical, but when and how is undetermined

    Asthma among children is a major public health problem worldwide. There are increasing number of studies suggesting a possible association between allergenic pollen and exacerbations of asthma. In the context of global climate change, a number of future climate and air pollution scenarios predict increases in concentrations of pollen, an extension of the pollen season, and an increase in the allergenicity of pollen. The goal of the present study is to evaluate the short-term effects of exposure to grass and weed pollen on emergency department visits and readmissions for asthma among children aged 0-9 years living in Montreal between April and October, 1994-2004. Time-series analyses were carried out using parametric log-linear overdispersed Poisson models that were adjusted for temporal variations, daily weather conditions (temperature, atmospheric pressure), and gaseous air pollutants (ozone and nitrogen dioxide). We have found positive associations between emergency department visits and concentrations of grass pollen 3 days after exposure. The effect of grass pollen was higher on emergency department readmissions as compared to initial visits. Weak negative associations were found between weed pollen (including ragweed pollen) and emergency department visits 2 days after exposure. The data indicate that among children, emergency department visits increased with increasing concentrations of grass pollen.

  16. Increased Arctic Deposition of Persistent Compounds as a Result of the Montreal Protocol

    Perfluorocarboxylic acids (PFCAs) are among the diverse groups of compounds characterized as persistent organic pollutants. They are toxic, resistant to environmental degradation, and adversely impact human and environmental health. PFCAs with four or fewer carbons, short-chain PFCAs (scPFCAs), are of particular interest because of their increasing levels in the environment, toxicity to plants, and potential for accumulation in some aquatic ecosystems, making them an emerging environmental concern. A minor source of scPFCAs to the Arctic has been shown to be atmospheric transformation of fluoropolymer precursors, followed by deposition. Additional potential sources of scPFCAs to the Arctic are chlorofluorocarbon (CFC)-replacement compounds. Through analysis of an ice core from the Canadian High Arctic, we show that Montreal Protocol-mandated introduction of CFC-replacement compounds for the heat-transfer industry has led to increasing inputs of these scPFCAs to the remote environment. Flux measurements for scPFCAs as a class of contaminants have only been reported in a couple studies to date. Here, we provide the first multi-decadal temporal record of scPFCA deposition, demonstrating a dramatic increase in deposition resulting from emission of CFC-replacements. These results bring to the forefront a need for a holistic approach to environmental risk assessment that considers impacts of replacement substances and degradation products.

  17. Comparison of Alternate and Original Items on the Montreal Cognitive Assessment.

    Lebedeva, Elena; Huang, Mei; Koski, Lisa

    2016-03-01

    The Montreal Cognitive Assessment (MoCA) is a screening tool for mild cognitive impairment (MCI) in elderly individuals. We hypothesized that measurement error when using the new alternate MoCA versions to monitor change over time could be related to the use of items that are not of comparable difficulty to their corresponding originals of similar content. The objective of this study was to compare the difficulty of the alternate MoCA items to the original ones. Five selected items from alternate versions of the MoCA were included with items from the original MoCA administered adaptively to geriatric outpatients (N = 78). Rasch analysis was used to estimate the difficulty level of the items. None of the five items from the alternate versions matched the difficulty level of their corresponding original items. This study demonstrates the potential benefits of a Rasch analysis-based approach for selecting items during the process of development of parallel forms. The results suggest that better match of the items from different MoCA forms by their difficulty would result in higher sensitivity to changes in cognitive function over time.

    2006-01-01

    Aujourd'hui, les façons de produire, d'organiser, d'évaluer et d'utiliser les savoirs sont en profond débat. De plus en plus, l'Etat, la société civile et l'économie tentent d'influencer les activités des universités et des laboratoires de recherche. Ces développements mettent à l'épreuve tout à la fois les fondements des systèmes d'enseignement supérieur et de recherche, l'autonomie des institutions scientifiques, la définition des frontières des savoirs et l'acceptation des sciences. Dans des contextes suisses et européens, cet ouvrage s'intéresse aux manières dont les sciences et les technologies sont fabriquées, en analysant leurs institutions et les pratiques. A partir d'une approche relationnelle, les sciences et les technologies sont conçues comme des phénomènes profondément sociaux, culturels et politiques. Une telle démarche déstabilise les visions parfois idéalisées et stéréotypées de la construction des savoirs. Des études de cas détaillées décrivent des phénomè...

  4. Velódromo Olímpico de Montreal – Canadá

    Taillibert, Roger

    1976-12-01

    Full Text Available This stadium is one of the most interesting ones that have been constructed lately. It has the following basic conditions: harmonious integration with the other Olympic installations; possibilities for future enlargements; total absence of supports; perfect permeability for the natural daylight; and perfect insulations in view of the hard climate of Montreal. Bearing these features in mind, the building consists of two parts: — The velodrome itself with lawn; 285.70 m long and 7.50 m wide courses with a slope varying between 18° and 48° with regard to the horizontal line; gallery for the public; auxiliary premises; dressing rooms, etc. — And the regular spheric roof the plan form of which represents three segments beginning with one buttress in the northeast end and increasing to three buttresses in the southeast end. This entirely self-supporting dome is 172 m long with a maximum height of 32 m. The total surface is 15,000 m2. The work was calculated by means of computers and was carried out with prefabricated pieces of concrete so as to achieve a better quality control of the concrete, and above all, a greater exactness of the prefabricated members. This was an indispensable factor in this case, where the maximum admissible error in most of the pieces was only 1.5 mm.Es uno de los estadios más interesantes de los últimos tiempos, con las siguientes condiciones básicas: armónica integración con las restantes instalaciones olímpicas; posibilidad de transformación para futuras aplicaciones; total ausencia de soportes; amplia permeabilidad a la luz natural; y perfecta estanquidad ante las duras condiciones climáticas de Montreal. Partiendo de estas premisas, el edificio consta de dos partes: — El velódromo propiamente dicho, con: césped; pista de carreras de 285,70 m de desarrollo, 7,50 m de anchura e inclinación variable entre 18° y 48° respecto a la horizontal; gradas para el público; locales auxiliares

    Advances in diagnostic and therapeutic modalities for congenital cytomegalovirus (CMV) infection have generated a mounting interest in identifying mothers susceptible to CMV. The objectives of this study were to evaluate the prevalence and socio-demographic determinants of CMV susceptibility and CMV awareness, among pregnant women, in Montreal, Quebec. Between April and December 2012, women delivering at Centre Hospitalier Universitaire Sainte Justine were recruited for the study. Stored serum from the first trimester of pregnancy was tested for CMV IgG. Knowledge about CMV and socio-demographic characteristics were collected via standardized questionnaire. Four hundred and ninety one women were enrolled in the study. Overall, 225 mothers (46%) were seronegative for CMV, and 85% (n = 415) were unaware of CMV or the associated risks in pregnancy. Significant risk factors for CMV seronegative status included Canadian vs. foreign born (aOR 6.88, 95% CI 4.33-10.94), and high vs. low family income (aOR 4.68, 95% CI 2.09-10.48). Maternal employment status was the only significant predictor of CMV unawareness, with unemployed mothers at the highest risk (aOR 85.6, 95% CI 17.3-421.3). Nearly half of pregnant women studied were at risk of primary infection, and yet, the majority was unaware of potential risks associated with CMV. Canadian born mothers and those with a high socioeconomic status were more likely to be CMV seronegative. Increased education about CMV infection, through public health interventions and obstetrician/pediatric counseling, is needed for all pregnant women.

  6. Montreal Archive of Sleep Studies: an open-access resource for instrument benchmarking and exploratory research.

    O'Reilly, Christian; Gosselin, Nadia; Carrier, Julie; Nielsen, Tore

    2014-12-01

    Manual processing of sleep recordings is extremely time-consuming. Efforts to automate this process have shown promising results, but automatic systems are generally evaluated on private databases, not allowing accurate cross-validation with other systems. In lacking a common benchmark, the relative performances of different systems are not compared easily and advances are compromised. To address this fundamental methodological impediment to sleep study, we propose an open-access database of polysomnographic biosignals. To build this database, whole-night recordings from 200 participants [97 males (aged 42.9 ± 19.8 years) and 103 females (aged 38.3 ± 18.9 years); age range: 18-76 years] were pooled from eight different research protocols performed in three different hospital-based sleep laboratories. All recordings feature a sampling frequency of 256 Hz and an electroencephalography (EEG) montage of 4-20 channels plus standard electro-oculography (EOG), electromyography (EMG), electrocardiography (ECG) and respiratory signals. Access to the database can be obtained through the Montreal Archive of Sleep Studies (MASS) website (http://www.ceams-carsm.ca/en/MASS), and requires only affiliation with a research institution and prior approval by the applicant's local ethical review board. Providing the research community with access to this free and open sleep database is expected to facilitate the development and cross-validation of sleep analysis automation systems. It is also expected that such a shared resource will be a catalyst for cross-centre collaborations on difficult topics such as improving inter-rater agreement on sleep stage scoring. © 2014 European Sleep Research Society.

    2017-08-01

    To examine variations between immigrants and nonimmigrants in 1) prevalence of common mental disorders and other mental health variables; 2) health service utilisation for emotional problems, mental disorders, and addictions, and 3) health service satisfaction. This article is based on a longitudinal cohort study conducted from May 2007 to the present: the Epidemiological Catchment Area Study of Montreal South-West (ZEPSOM). Participants were followed up at 4 time points (T1, n = 2433; T4, n = 1095). Core exposure variables include immigrant status (immigrant vs. nonimmigrant), duration of residence, and region of origin. Key outcome variables included mental health status, health service utilisation, and health service satisfaction. Data were analysed both cross-sectionally and longitudinally. Immigrants had been in Canada for 20 years on average. Immigrants had significantly lower rates of high psychological distress (32.6% vs. 39.1%, P = 0.016), alcohol dependence (1.4% vs. 3.9%, P =0.010), depression (5.2% vs. 9.2%, P = 0.008), and various other mental disorders. They had significantly higher scores of mental well-being (48.9 vs. 47.1 score, P = 0.014) and satisfaction with social (34.0 vs. 33.4 score, P = 0.021) and personal relationships (16.7 vs. 15.6 score, P Immigrants had significantly lower rates of health service utilisation for emotional problems, mental disorders, and addictions and significantly higher rates of health service satisfaction at all time points. Asian and African immigrants had particularly low rates of utilisation and high rates of satisfaction. Immigrants had better overall mental health than nonimmigrants.

  8. Latent segmentation based count models: Analysis of bicycle safety in Montreal and Toronto.

    Yasmin, Shamsunnahar; Eluru, Naveen

    2016-10-01

    The study contributes to literature on bicycle safety by building on the traditional count regression models to investigate factors affecting bicycle crashes at the Traffic Analysis Zone (TAZ) level. TAZ is a traffic related geographic entity which is most frequently used as spatial unit for macroscopic crash risk analysis. In conventional count models, the impact of exogenous factors is restricted to be the same across the entire region. However, it is possible that the influence of exogenous factors might vary across different TAZs. To accommodate for the potential variation in the impact of exogenous factors we formulate latent segmentation based count models. Specifically, we formulate and estimate latent segmentation based Poisson (LP) and latent segmentation based Negative Binomial (LNB) models to study bicycle crash counts. In our latent segmentation approach, we allow for more than two segments and also consider a large set of variables in segmentation and segment specific models. The formulated models are estimated using bicycle-motor vehicle crash data from the Island of Montreal and City of Toronto for the years 2006 through 2010. The TAZ level variables considered in our analysis include accessibility measures, exposure measures, sociodemographic characteristics, socioeconomic characteristics, road network characteristics and built environment. A policy analysis is also conducted to illustrate the applicability of the proposed model for planning purposes. This macro-level research would assist decision makers, transportation officials and community planners to make informed decisions to proactively improve bicycle safety - a prerequisite to promoting a culture of active transportation.

  9. Revising the diagnosis of congenital amusia with the Montreal Battery of Evaluation of Amusia.

    Pfeifer, Jasmin; Hamann, Silke

    2015-01-01

    This article presents a critical survey of the prevalent usage of the Montreal Battery of Evaluation of Amusia (MBEA; Peretz et al., 2003) to assess congenital amusia, a neuro-developmental disorder that has been claimed to be present in 4% of the population (Kalmus and Fry, 1980). It reviews and discusses the current usage of the MBEA in relation to cut-off scores, number of used subtests, manner of testing, and employed statistics, as these vary in the literature. Furthermore, data are presented from a large-scale experiment with 228 German undergraduate students who were assessed with the MBEA and a comprehensive questionnaire. This experiment tested the difference between scores that were obtained in a web-based study (at participants' homes) and those obtained under laboratory conditions with a computerized version of the MBEA. In addition to traditional statistical procedures, the data were evaluated using Signal Detection Theory (SDT; Green and Swets, 1966), taking into consideration the individual's ability to discriminate and their response bias. Results show that using SDT for scoring instead of proportion correct offers a bias-free and normally distributed measure of discrimination ability. It is also demonstrated that a diagnosis based on an average score leads to cases of misdiagnosis. The prevalence of congenital amusia is shown to depend highly on the statistical criterion that is applied as cut-off score and on the number of subtests that is considered for the diagnosis. In addition, three different subtypes of amusics were found in our sample. Lastly, significant differences between the web-based and the laboratory group were found, giving rise to questions about the validity of web-based experimentation.

    To compare the validity of the Montreal Cognitive Assessment (MoCA) with the criterion standard of standardized neuropsychological testing and to compare the convergent validity of the MoCA with that of existing screening tools and global measures of cognition. Cross-sectional observational study. Tertiary care hospital-based cognitive neurology subspecialty clinic. A convenience sample of 107 individuals with mild Alzheimer's disease (AD, n=75) or mild cognitive impairment (MCI, n=32) from the Sunnybrook Dementia Study. In addition to the MoCA, all participants completed the Mini-Mental State Examination (MMSE), the Mattis Dementia Rating Scale (DRS), and detailed neuropsychological testing. Convergent validity was supported, with MoCA scores correlating well with the MMSE (correlation coefficient (r)=0.66, Pvalidity was supported, with MoCA subscores according to cognitive domain correlating well with analogous neuropsychological tests and, in the case of memory (area under the receiver operating characteristic curve (AUC)=0.86), executive (AUC=0.79), and visuospatial function (AUC=0.79), being reasonably sensitive to impairment in those domains. The MoCA is a valid assessment of cognition that shows good agreement with existing screening tools and global measures (convergent validity) and was superior to the MMSE in this regard. The MoCA domain-specific subscores align with performance on more-detailed neuropsychological tests, suggesting not only good criterion validity for the MoCA, but also that it may be useful in guiding further neuropsychological testing. © 2013, Copyright the Authors Journal compilation © 2013, The American Geriatrics Society.

  13. Montreal Cognitive Assessment and Mini-Mental State Examination are both valid cognitive tools in stroke.

    2013-08-01

    To determine the validity of the Montreal Cognitive Assessment (MoCA) and the Mini-Mental State Examination (MMSE) as screening tools for cognitive impairment after stroke. Cognitive assessments were administered over 2 sessions (1 week apart) at 3 months post-stroke. Scores on the MoCA and MMSE were evaluated against a diagnosis of cognitive impairment derived from a comprehensive neuropsychological battery (the criterion standard). Sixty patients participated in the study [mean age 72.1 years (SD = 13.9), mean education 10.5 years (SD = 3.9), median acute NIHSS score 5 (IQR 3-7)]. The MoCA yielded lower scores (median = 21, IQR = 17-24; mean = 20.0, SD = 5.4) than the MMSE (median = 26, IQR = 22-27; mean = 24.2, SD = 4.5). MMSE data were more skewed towards ceiling than MoCA data (skewness = -1.09 vs -0.73). Area under the receiver operator curve was higher for MoCA than for MMSE (0.87 vs 0.84), although this difference was not significant (χ(2) = 0.48, P = 0.49). At their optimal cut-offs, the MoCA had better sensitivity than the MMSE (0.92 vs 0.82) but poorer specificity (0.67 vs 0.76). The MoCA is a valid screening tool for post-stroke cognitive impairment; it is more sensitive but less specific than the MMSE. Contrary to the prevailing view, the MMSE also exhibited acceptable validity in this setting. © 2013 John Wiley & Sons A/S.

  14. Evaluating the relationship between education level and cognitive impairment with the Montreal Cognitive Assessment Test.

    Yancar Demir, Esra; Özcan, Tuba

    2015-09-01

    Mild cognitive impairment (MCI) is defined as 'a cognitive decline greater than that expected for an individual's age and education level but that does not interfere notably with activities of daily life'. The Montreal Cognitive Assessment (MoCA) is a screening test for MCI. We investigated the performance of the Turkish version of the MoCA in detecting MCI among elderly persons in a rural area, the majority of whom have a low level of education. We evaluated 50 consecutive men referred from an outpatient clinic. Educational level was divided into three categories: group 1, less than primary (5 years). We evaluated the effect of education on MoCA scores and compared subjects' test performance among the different categories of education level. A total of 50 male patients with MCI (mean age: 70.74 ± 7.87) met the inclusion criteria. There were no differences in the total scores based on education or in the subscores for visuospatial/executive function, naming, attention, abstraction and delayed recall. Language was the only domain that showed significant differences between the groups. In post-hoc analysis, differences were found between groups 1 and 3 and between groups 1 and 2. Group 1 had significantly lower scores for language. The repeat subscore for language was significantly lower in group 1 than in group 2. In fluency, there were significant differences between groups 2 and 3 and between group 1 and 3. To our knowledge, this is the first study to analyze the applicability of the Turkish version of MoCA in populations with little education. Our results emphasize the need to adapt the language sections of this test, so it can be easily used in populations with low education levels. © 2014 The Authors.

  19. Architecture, religion, and tuberculosis in Sainte-Agathe-des-Monts, Quebec.

    Adams, Annmarie; Poutanen, Mary Anne

    2009-01-01

    This paper explores the architecture of the Mount Sinai Sanatorium in Sainte-Agathe-des-Monts (Qc) to disentangle the role of religion in the treatment of tuberculosis. In particular, we analyze the design of Mount Sinai, the jewel in the crown of Jewish philanthropy in Montreal, in relation to that of the nearby Laurentian Sanatorium. While Mount Sinai offered free treatment to the poor in a stunning, Art Deco building of 1930, the Protestant hospital had by then served paying patients for more than two decades in a purposefully home-like, Tudor-revival setting. Using architectural historian Bernard Herman's concept of embedded landscapes, we show how the two hospitals differed in terms of their relationship to site, access, and, most importantly, to city, knowledge, and community. Architects Scopes & Feustmann, who designed the Laurentian hospital, operated an office at Saranac Lake, New York, America's premier destination for consumptives. The qualifications of Mount Sinai architects Spence & Goodman, however, derived from their experience with Jewish institutions in Montreal. Following Herman's approach to architecture through movement and context, how did notions of medical therapy and Judaism intersect in the plans of Mount Sinai?

    To identify the factors that influence the use of dental services in 4-7-year-olds and in 10-13-year-olds resident in the cities of Talca (Chile) and Montreal (Canada). A nonprobabilistic cross-sectional study was carried out in 147 boys and girls in Talca and in 94 boys and girls in Montreal between 2009 and 2011. Sociodemographic variables were recorded in parents and children, including age and sex. Data were also gathered on parental education, family composition, and proximity to health centers within neighborhoods. The data were analyzed with Fisher's exact test and the robust Cox regression model (with constant time) with a significance level of 0,05. In Talca, parental education was significantly associated with dental care visits at least twice a year. The children of parents with university education were 2.20 times more likely to consult a dentist (95% CI: 1.30-3.73). Children whose parents perceived their children's health positively were 53% (OR = 0,47; 95% CI: 0,28-0,77) less likely to consult a dentist. In Montreal, the children of parents with university education were 2.10 times more likely to consult a dentist (95%CI: 1.17-3.76), while older children (10-13 years) were 2.11 (95% CI: 1.15-3.88) times more likely to consult a dentist. In both cities, parental education level was associated with the use of dental services. Copyright © 2012 SESPAS. Published by Elsevier Espana. All rights reserved.

  3. Use of alumni and employer surveys for internal quality assurance of the DVM program at the University of Montreal.

    Doucet, Michèle Y; Vrins, André

    2010-01-01

    Annual alumni and employer surveys, initially designed as outcomes assessment tools, were integrated into a new internal quality assurance strategy to improve the doctor of veterinary medicine program at the University of Montreal's Faculté de Médecine Vétérinaire. Data collected annually from the classes of 2004-2007 indicated that alumni and their employers were generally satisfied with their level of preparation after one year of professional activity. Specific weaknesses were found in non-technical skills such as communication and resource management. These data were used in support of other forms of feedback to guide curricular reform.

    Parkinson disease dementia dramatically increases mortality rates, patient expenditures, hospitalization risk, and caregiver burden. Currently, predicting Parkinson disease dementia risk is difficult, particularly in an office-based setting, without extensive biomarker testing. To appraise the predictive validity of the Montreal Parkinson Risk of Dementia Scale, an office-based screening tool consisting of 8 items that are simply assessed. This multicenter study (Montreal, Canada; Tottori, Japan; and Parkinson Progression Markers Initiative sites) used 4 diverse Parkinson disease cohorts with a prospective 4.4-year follow-up. A total of 717 patients with Parkinson disease were recruited between May 2005 and June 2016. Of these, 607 were dementia-free at baseline and followed-up for 1 year or more and so were included. The association of individual baseline scale variables with eventual dementia risk was calculated. Participants were then randomly split into cohorts to investigate weighting and determine the scale's optimal cutoff point. Receiver operating characteristic curves were calculated and correlations with selected biomarkers were investigated. Dementia, as defined by Movement Disorder Society level I criteria. Of the 607 patients (mean [SD] age, 63.4 [10.1]; 376 men [62%]), 70 (11.5%) converted to dementia. All 8 items of the Montreal Parkinson Risk of Dementia Scale independently predicted dementia development at the 5% significance level. The annual conversion rate to dementia in the high-risk group (score, >5) was 14.9% compared with 5.8% in the intermediate group (score, 4-5) and 0.6% in the low-risk group (score, 0-3). The weighting procedure conferred no significant advantage. Overall predictive validity by the area under the receiver operating characteristic curve was 0.877 (95% CI, 0.829-0.924) across all cohorts. A cutoff of 4 or greater yielded a sensitivity of 77.1% (95% CI, 65.6-86.3) and a specificity of 87.2% (95% CI, 84.1-89.9), with a

  5. A Decontamination Process to Remove Metals and Stabilise Montreal Sewage Sludge

    G. Mercier

    2002-01-01

    Full Text Available The Montreal Urban Community (MUC treatment plant produces approximately 270 tons of dry sludge daily (tds/day during physicochemical wastewater treatment. The sludges are burned and contribute to the greenhouse effect by producing atmospheric CO2. Moreover, the sludge emanates a nauseating odour during its thermal stabilisation and retains unpleasant odours for the part (25% that is dried and granulated. To solve this particular problem, the treatment plant authorities are currently evaluating an acidic chemical leaching (sulfuric or hydrochloric acid process at a pH between 2 and 3, using an oxidizing agent such as ferric chloride or hydrogen peroxide (METIX-AC technology, patent pending; [20]. They could integrate it to a 70 tds/day granulated sludge production process. Verification of the application of METIX-AC technology was carried out in a pilot plant set up near the sludge production plant of the MUC. The tests showed that METIX-AC technology can be advantageously integrated to the process used at the MUC. The residual copper (274 ± 58 mg/kg and cadmium (5.6 ± 2.9 mg/kg concentrations in the treated sludge meet legislation standards. The results have also shown that odours have been significantly eliminated for the dewatered, decontaminated, and stabilized biosolids (> 97% compared to the non-decontaminated biosolids. A high rate of odour elimination also was obtained for the liquid leached biosolids (> 93%, compared to the untreated liquid biosolids. The fertilising value (N and P is well preserved by the METIX-AC process. Dissolved organic carbon measurements have showed that little organic matter is brought in solution during the treatment. In fact, the average concentration of dissolved organic carbon measured in the treated liquid phase is 966 ± 352 mg/l, whereas it is 1190 ± 325 mg/l in untreated sludge. The treated sludge was first conditioned with an organic polymer and a coagulant aid. It was successfully dewatered with

  6. Associations between ambient air pollution and daily mortality among elderly persons in Montreal, Quebec.

    Goldberg, Mark S; Burnett, Richard T; Stieb, David M; Brophy, James M; Daskalopoulou, Stella S; Valois, Marie-France; Brook, Jeffrey R

    2013-10-01

    Persons with underlying health conditions may be at higher risk for the short-term effects of air pollution. We have extended our original mortality time series study in Montreal, Quebec, among persons 65 years of age and older, for an additional 10 years (1990-2003) to assess whether these associations persisted and to investigate new health conditions. We created subgroups of subjects diagnosed with major health conditions one year before death using billing and prescription data from the Quebec Health Insurance Plan. We used parametric log-linear Poisson models within the distributed lag non-linear models framework, that were adjusted for long-term temporal trends and daily maximum temperature, for which we assessed associations with NO2, O3, CO, SO2, and particles with aerodynamic diameters 2.5 μm in diameter or less (PM2.5). We found positive associations between daily non-accidental mortality and all air pollutants but O3 (e.g., for a cumulative effect over a 3-day lag, with a mean percent change (MPC) in daily mortality of 1.90% [95% confidence interval: 0.73, 3.08%] for an increase of the interquartile range (17.56 μg m(-3)) of NO2). Positive associations were found amongst persons having cardiovascular disease (cumulative MPC for an increase equal to the interquartile range of NO2=2.67%), congestive heart failure (MPC=3.46%), atrial fibrillation (MPC=4.21%), diabetes (MPC=3.45%), and diabetes and cardiovascular disease (MPC=3.50%). Associations in the warm season were also found for acute and chronic coronary artery disease, hypertension, and cancer. There was no persuasive evidence to conclude that there were seasonal associations for cerebrovascular disease, acute lower respiratory disease (defined within 2 months of death), airways disease, and diabetes and airways disease. These data indicate that individuals with certain health conditions, especially those with diabetes and cardiovascular disease, hypertension, atrial fibrillation, and cancer, may

    2013-01-01

    Écrire l'histoire de l'Univers, tel est l'objectif commun des physiciens des particules et des astrophysiciens. Pour y parvenir, deux approches s'épaulent : la voie de l'infiniment petit, que l'on emprunte via de gigantesques accélérateurs de particules, et celle de l'infiniment grand, dont le laboratoire est l'Univers. Un Univers qui est bien loin d'avoir livré tous ses secrets. On connaît à peine 4,8 % de la matière qui le constitue, le reste étant composé de matière noire (25,8 %) et d'énergie noire (69,4 %), toutes deux de nature inconnue. Et si la récente découverte du boson de Higgs valide le Modèle standard de la physique des particules, celui-ci est toujours incomplet et doit être étendu à ou dépassé. Est-on arrivé au bout du jeu de poupées russes de la matière ? Quelles sont les particules manquantes ? Faut-il revoir les lois fondamentales ?

  12. Injectabilite des coulis de ciment dans des milieux fissures

    Mnif, Thameur

    Le travail presente ici est un bilan du travaux de recherche effectues sur l'injectabilite des coulis de ciment dans lu milieux fissures. Un certain nombre de coulis a base de ciment Portland et microfin ont ete selectionnes afin de caracteriser leur capacite a penetrer des milieux fissures. Une partie des essais a ete menee en laboratoire. L'etude rheologique des differents melanges a permis de tester l'influence de l'ajout de superplastifiant et/ou de fumee de silice sur la distribution granulometrique des coulis et par consequent sur leur capacite a injecter des colonnes de sable simulant un milieu fissure donne. La classe granulometrique d'un coulis, sa stabilite et sa fluidite sont apparus comme les trois facteurs principaux pour la reussite d'une injection. Un facteur de finesse a ete defini au cours de cette etude: base sur la classe granulometrique du ciment et sa stabilite, il peut entrer dans la formulation theorique du debit d'injection avant application sur chantier. La deuxieme et derniere partie de l'etude presente les resultats de deux projets de recherche sur l'injection realises sur chantier. L'injection de dalles de beton fissurees a permis le suivi de l'evolution des pressions avec la distance au point d'injection. L'injection de murs de maconnerie a caractere historique a montre l'importance de la definition de criteres de performance des coulis a utiliser pour traiter un milieu donne et pour un objectif donne. Plusieurs melanges peuvent ainsi etre predefinis et mis a disposition sur le chantier. La complementarite des ciments traditionnels et des ciments microfins devient alors un atout important. Le choix d'utilisation de ces melanges est fonction du terrain rencontre. En conclusion, cette recherche etablit une methodologie pour la selection des coulis a base de ciment et des pressions d'injection en fonction de l'ouverture des fissures ou joints de construction.

  14. Acquisition and Processing of High Resolution Hyperspectral Imageries for the 3d Mapping of Urban Heat Islands and Microparticles of Montreal

    Mongeau, R.; Baudouin, Y.; Cavayas, F.

    2017-10-01

    Ville de Montreal wanted to develop a system to identify heat islands and microparticles at the urban scale and to study their formation. UQAM and UdeM universities have joined their expertise under the framework "Observatoire Spatial Urbain" to create a representative geospatial database of thermal and atmospheric parameters collected during the summer months. They innovated in the development of a methodology for processing high resolution hyperspectral images (1-2 m). In partnership with Ville de Montreal, they integrated 3D geospatial data (topography, transportation and meteorology) in the process. The 3D mapping of intraurban heat islands as well as air micro-particles makes it possible, initially, to identify the problematic situations for future civil protection interventions during extreme heat. Moreover, it will be used as a reference for the Ville de Montreal to establish a strategy for public domain tree planting and in the analysis of urban development projects.

    Crohn's disease (CD) is a chronic inflammation of the gastrointestinal tract associated with life-long high health care costs. We aimed to determine the effect of disease phenotype on cost. Clinical and economic data of a community-based CD cohort with 10-year follow-up were analyzed retrospectively in relation to Montreal classification phenotypes. In 418 patients, mean total costs of health care for the behavior phenotypes were: nonstricturing-nonpenetrating 1690, stricturing 2081, penetrating 3133 and penetrating-with-perianal-fistula 3356 €/patient-phenotype-year (P<0.001), and mean costs of surgical hospitalization 215, 751, 1293 and 1275 €/patient-phenotype-year respectively (P<0.001). Penetrating-with-perianal-fistula patients incurred significantly greater expenses than penetrating patients for total care, diagnosis and drugs, but not surgical hospitalization. Total costs were similar in the location phenotypes: ileum 1893, colon 1748, ileo-colonic 2010 and upper gastrointestinal tract 1758 €/patient-phenotype-year, but surgical hospitalization costs differed significantly, 558, 209, 492 and 542 €/patient-phenotype-year respectively (P<0.001). By multivariate analysis, the behavior phenotype significantly impacted total, medical and surgical hospitalization costs, whereas the location phenotype affected only surgical costs. Younger age at diagnosis predicted greater surgical expenses. Behavior is the dominant phenotype driving health care cost. Use of the Montreal classification permits detection of cost differences caused by perianal fistula.

    Dementia is a progressive syndrome of global cognitive impairment with significant health and social care costs. Global prevalence is projected to increase, particularly in resource-limited settings. Recent policy changes in Western countries to increase detection mandates a careful examination of the diagnostic accuracy of neuropsychological tests for dementia. To determine the diagnostic accuracy of the Montreal Cognitive Assessment (MoCA) at various thresholds for dementia and its subtypes. We searched MEDLINE, EMBASE, BIOSIS Previews, Science Citation Index, PsycINFO and LILACS databases to August 2012. In addition, we searched specialised sources containing diagnostic studies and reviews, including MEDION (Meta-analyses van Diagnostisch Onderzoek), DARE (Database of Abstracts of Reviews of Effects), HTA (Health Technology Assessment Database), ARIF (Aggressive Research Intelligence Facility) and C-EBLM (International Federation of Clinical Chemistry and Laboratory Medicine Committee for Evidence-based Laboratory Medicine) databases. We also searched ALOIS (Cochrane Dementia and Cognitive Improvement Group specialized register of diagnostic and intervention studies). We identified further relevant studies from the PubMed 'related articles' feature and by tracking key studies in Science Citation Index and Scopus. We also searched for relevant grey literature from the Web of Science Core Collection, including Science Citation Index and Conference Proceedings Citation Index (Thomson Reuters Web of Science), PhD theses and contacted researchers with potential relevant data. Cross-sectional designs where all participants were recruited from the same sample were sought; case-control studies were excluded due to high chance of bias. We searched for studies from memory clinics, hospital clinics, primary care and community populations. We excluded studies of early onset dementia, dementia from a secondary cause, or studies where participants were selected on the basis

  3. Mykotische Infektionen des Penis

    Mayser P

    1999-01-01

    Full Text Available Die häufigste mykotische Infektion des Penis stellt die Balanitis/Balonoposthitis durch Candida albicans dar. Sie weist eine steigende Inzidenz auf und scheint vornehmlich durch Genitalverkehr übertragen zu werden. Penile Infektionen durch Dermatophyten sind sehr selten, obwohl die Tinea inguinalis zu den häufigeren Erkrankungen zählt. Eine Mitbeteiligung des Penis im Rahmen von Systemmykosen kennzeichnet zumeist ein schwer verlaufende Erkrankung. Ursächlich kann beim immunoinkompetenten Patienten nahezu jeder Erreger in Frage kommen. Biopsie sowie Gewebekultur aus den meist ulzerativen Veränderungen können die Diagnose sichern. Die meisten superfiziellen Infektionen sprechen zufriedenstellend auf eine topische antimykotische Behandlung an, insbesondere wenn Provokationsfaktoren und die Möglichkeit der sexuellen Transmission berücksichtigt werden. Ausgedehnte Infektionen durch Dermatophyten, Hefen und natürlich systemische Infektionen erfordern eine systemische antimykotische Therapie.

    Die Organtransplantation stellt eine verbreitete Therapie dar, um bei krankheitsoder unfallbedingter Schädigung eines Organs die Gesamtheit seiner Funktionen wieder herzustellen, indem es durch ein Spenderorgan ersetzt wird. Organtransplantationen werden für die Leber, die Niere, die Lunge, das Herz oder bei schweren grossflächigen Verbrennungen der Haut vorgenommen. Der grosse apparative, personelle und logistische Aufwand und die Risiken der Transplantationschirurgie (Abstossungsreaktionen) sowie die mangelnde Verfügbarkeit von immunologisch kompatiblen Spenderorganen führen jedoch dazu, dass der Bedarf an Organtransplantaten nur zu einem sehr geringen Teil gedeckt werden kann. Sind Spenderorgane nicht verfügbar, können in einzelnen Fällen lebenswichtige Teilfunktionen, wie beispielsweise die Filtrationsfunktion der Niere durch die Blutreinigung mittels Dialyse ersetzt oder, bei mangelnder Funktion der Bauchspeicheldrüse (Diabetes), durch die Verabreichung von Insulin ein normaler Zustand des Gesamtorganismus auch über Jahre hinweg erhalten werden. Bei der notwendigen lebenslangen Anwendung apparativer oder medikamentöser Therapie können für den Patienten jedoch häufig schwerwiegende, möglicherweise lebensverkürzende Nebenwirkungen entstehen. Daher werden in der Forschung Alternativen gesucht, um die Funktionen des ausgefallenen Organs durch die Implantation von Zellen oder in vitro gezüchteten Geweben möglichst umfassend wieder herzustellen. Dies erfordert biologisch aktive Implantate, welche die für den Stoffwechsel des Organs wichtigen Zellen enthalten und einen organtypischen Stoffwechsel entfalten.

    Full Text Available Le but de cet article est de comprendre l’incidence sémiotique du nettoyage d’un tableau ainsi que la résultante cognitive induite sur l’observateur. Cette étude confronte l’analyse des phénomènes visuels engendrés par le jaunissement du vernis et son retrait, à des entretiens réalisés à dessein. Le retrait d’un vernis jauni change considérablement l’image. L’heure, le climat, la saison et l’activité même des personnages s’en trouvent ainsi modifié. La patine peut être perçue, soit comme un obstacle à l’exploration, soit pour ceux qui l’apprécient, comme le medium d’une relation plus intime entre l’œuvre et l’observateur.The purpose of this article is to understand the semiotic impact of the cleaning of a painting and the cognitive effects induced on the observer. This study analyses conjointly the visual phenomenon generated by yellowing varnish and its removal and controlled interviews of observers.The removal of yellowing varnish modifies considerably the perception of the picture. Daytime, climate, season and characters activities are modified. The patina may be perceived either as an obstacle to the painting exploration, or, for those who appreciate it, as a medium for a closer relationship between the painting and the observer.

  11. Evaluation of air quality in arenas on the Island of Montreal : winter 2006-2007; Evaluation de la qualite de l'air dans les arenas de l'Ile de Montreal

    Price, K.; Beausoleil, M.; Lefebvre, L.

    2007-03-15

    For the past twenty years, cases of nitrogen dioxide (NO{sub 2}) and carbon monoxide (CO) poisoning have been reported in arenas in Quebec. A 1997 evaluation of air quality in 332 arenas in 9 different countries revealed that 40 per cent of arenas worldwide have high concentration of NO{sub 2}. In Quebec, an air quality review at arenas in Montreal drew similar conclusions, that 69 per cent of the arenas have high concentrations of CO and/or NO{sub 2}. In 1997, Quebec's environmental health committee established criteria of 20 ppm for CO, and 0.5 ppm for NO{sub 2} in arenas, in order to ensure that athletes and the public at large do not suffer negative effects related to the presence of combustible gases. This information was distributed to the administrative personnel in arenas in Quebec by means of an awareness and information campaign. Since then, the number of arenas that have met these criteria for air quality in arenas in Montreal has climbed from 31 per cent in 1997 to 83 per cent in 2004. The practices put into action by arena administrators include: 1) regular maintenance of ice surface cleaning machines and other equipment that use fuel, 2) judicious use of ventilation so that gases can be evacuated from the premises, and, 3) periodic measurements of CO and NO{sub 2} during peak usage times such as tournaments. Other means of lowering gas emissions have also shown to be helpful, such as replacement of ice surface cleaning machines with electrical ones, installation of CO and NO{sub 2} detectors close to the rink surface so that ventilation machines could be activated, and the measurement and constant registration of these gases. It was concluded that these measures could help maintain good air quality in arenas. 15 refs., 1 tabs., 1 fig.

  2. Manganese concentrations in the air of the Montreal (Canada) subway in relation to surface automobile traffic density

    2006-07-31

    Methylcyclopentadienyl manganese tricarbonyl (MMT) is an organic derivative of manganese (Mn), used since 1976 in Canadian gasoline as an octane enhancer. Its combustion leads to the emission of Mn particles. Several studies carried out by our research group have established a correlation between atmospheric Mn concentrations and automobile traffic density, suggesting that MMT in gasoline could play a significant role. This study aims to measure Mn concentrations in the air of the underground subway in Montreal (Canada) and to examine the relation with nearby surface automobile traffic density and, by extension, with the use of MMT in gasoline. Three subway stations were chosen for their location in different microenvironments with different traffic densities. Respirable (MnR<5 {mu}m) and total Mn (MnT) were sampled over two weeks, 5 days/week, 12 h/day. For the station located in the lower traffic density area, relatively low levels of MnR and MnT were found, with averages of 0.018 and 0.032 {mu}g/m{sup 3}, respectively. These concentrations are within the range of the background levels in Montreal. For the other two stations, the average concentrations of MnR were twice as high and exceeded the US EPA reference concentration of 0.05 {mu}g/m{sup 3}. Although there may be several sources of Mn from different components of the subway structure and vehicles, no correlation was found between subway traffic and atmospheric Mn in the subway. Since the air in the underground subway is pumped directly from outside without filtration, our findings strongly suggest that the combustion of MMT in automobiles is an important factor. (author)

    2002-09-30

    Since the summer of 2001, 25 skating rinks from the territory of the old City of Montreal have been linked through a network to the remote management system. This initiative enables the people responsible for the skating rink to easily obtain statistics on the operation of refrigeration systems and to compile this information in the memory of a personal computer (PC). Each compressor system is equipped with a current transformer which acts as proof of monitored operation by the remote management system. Every minute, the compressors are asked in sequence to report on their status. The process by which the data is entered, filtered and analysed was explained and an example provided to better illustrate the concept. As a rule, management believes that it is possible to lower the power of existing refrigeration systems and to select new refrigeration systems according to the data acquired. Based on the results obtained so far, the power of some of the refrigeration systems has already been reduced by letting go one or two of the six refrigeration circuits of a skating rink. 2 tabs.

  4. Vecteurs Singuliers des Theories des Champs Conformes Minimales

    Benoit, Louis

    En 1984 Belavin, Polyakov et Zamolodchikov revolutionnent la theorie des champs en explicitant une nouvelle gamme de theories, les theories quantiques des champs bidimensionnelles invariantes sous les transformations conformes. L'algebre des transformations conformes de l'espace-temps presente une caracteristique remarquable: en deux dimensions elle possede un nombre infini de generateurs. Cette propriete impose de telles conditions aux fonctions de correlations qu'il est possible de les evaluer sans aucune approximation. Les champs des theories conformes appartiennent a des representations de plus haut poids de l'algebre de Virasoro, une extension centrale de l'algebre conforme du plan. Ces representations sont etiquetees par h, le poids conforme de leur vecteur de plus haut poids, et par la charge centrale c, le facteur de l'extension centrale, commune a toutes les representations d'une meme theorie. Les theories conformes minimales sont constituees d'un nombre fini de representations. Parmi celles-ci se trouvent des theories unitaires dont les representation forment la serie discrete de l'algebre de Virasoro; leur poids h a la forme h_{p,q}(m)=[ (p(m+1) -qm)^2-1] (4m(m+1)), ou p,q et m sont des entiers positifs et p+q= 2. Ces representations possedent un sous-espace invariant engendre par deux sous-representations avec h_1=h_{p,q} + pq et h_2=h_{p,q} + (m-p)(m+1-q) dont chacun des vecteurs de plus haut poids portent le nom de vecteur singulier et sont notes respectivement |Psi _{p,q}> et |Psi_{m-p,m+1-q}>. . Les theories super-conformes sont une version super-symetrique des theories conformes. Leurs champs appartiennent a des representation de plus haut poids de l'algebre de Neveu-Schwarz, une des deux extensions super -symetriques de l'algebre de Virasoro. Les theories super -conformes minimales possedent la meme structure que les theories conformes minimales. Les representations sont elements de la serie h_{p,q}= [ (p(m+2)-qm)^2-4] /(8m(m+2)) ou p,q et m sont

    Few studies have examined potential disparities in access to transportation infrastructures, an important determinant of population health. To examine individual- and area-level disparities in access to the road network, public transportation system, and a public bicycle share program in Montreal, Canada. Examining associations between sociodemographic variables and access to the road network, public transportation system, and a public bicycle share program, 6,495 adult respondents (mean age, 48.7 years; 59.0 % female) nested in 33 areas were included in a multilevel analysis. Individuals with lower incomes lived significantly closer to public transportation and the bicycle share program. At the area level, the interaction between low-education and low-income neighborhoods showed that these areas were significantly closer to public transportation and the bicycle share program controlling for individual and urbanicity variables. More deprived areas of the Island of Montreal have better access to transportation infrastructure than less-deprived areas.

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

    Lefebvre, G.; Joly, R.; Guay, T.

    2006-01-01

    This paper explored the environmental impacts associated with Petro-Canada's project to add petroleum product storage tanks to its refinery in the east-end of Montreal. The project plan is based on a 6 year horizon from 2006-2012. The additional reservoirs would store new products destined for the petrochemical industry and for consumers, thus improving the flexibility and reliability of the refinery. The products would include low sulfur diesel and ethanol gasoline. The project does not involve any increase in refining capacity, and is estimated to cost $15 million. The main issues associated with this project are ambient air quality, the protection of groundwater and soil, as well as the security of areas inhabited by neighbouring areas in risk of a major accident. Emissions of organic compounds, including benzene, are considered minimal considering the use of sealed floating roofs. Geomembranes will be installed under the storage tanks to ensure the protection of groundwater and soil. Any consequences to the population of neighbouring areas resulting from accidents inside the industrial park will be limited since the reservoirs will be located more than 1 km away from a populated area. Quebec's Ministry of Sustainable Development, Environment and Parks recommended that this project be approved as long as the terms and measures of environmental regulations are respected, and that an emergency plan is submitted before the operation of the first reservoir. 1 tab

  11. Academic performance and educational pathways of young allophones: A comparative multivariate analysis of Montreal, Toronto, and Vancouver

    Full Text Available Using several local and provincial data banks enabling one to follow the school progression of the cohort of students who, in Canada’s three main immigration-destination cities, were expected to graduate secondary school in 2004, this article examines the academic performance and educational pathways of those students who at home use a language other the main language of schooling: non-French speakers in Montreal and non-English speakers in Toronto and Vancouver. First, after accounting for differences in characteristics, those students (target group are shown to succeed better than the remaining students (comparison group, especially in Vancouver. However, within the target group, there appear to be substantial differences in performance between linguistic subgroups, which are far from being similar in all three cities. Second, the individual and contextual factors that influence the academic performance of the students in the target group appear to be similar for some and different for others in the three cities, while presenting some more-or-less large discrepancies with the corresponding factors pertaining to the comparison group. The article concludes with a few policy implications.

  12. Detection and Differentiation of Frontotemporal Dementia and Related Disorders From Alzheimer Disease Using the Montreal Cognitive Assessment.

    Coleman, Kristy K L; Coleman, Brenda L; MacKinley, Julia D; Pasternak, Stephen H; Finger, Elizabeth C

    2016-01-01

    The Montreal Cognitive Assessment (MoCA) is a cognitive screening tool used by practitioners worldwide. The efficacy of the MoCA for screening frontotemporal dementia (FTD) and related disorders is unknown. The objectives were: (1) to determine whether the MoCA detects cognitive impairment (CI) in FTD subjects; (2) to determine whether Alzheimer disease (AD) and FTD subtypes and related disorders can be parsed using the MoCA; and (3) describe longitudinal MoCA performance by subtype. We extracted demographic and testing data from a database of patients referred to a cognitive neurology clinic who met criteria for probable AD or FTD (N=192). Logistic regression was used to determine whether dementia subtypes were associated with overall scores, subscores, or combinations of subscores on the MoCA. Initial MoCA results demonstrated CI in the majority of FTD subjects (87%). FTD subjects (N=94) performed better than AD subjects (N=98) on the MoCA (mean scores: 18.1 vs. 16.3; P=0.02). Subscores parsed many, but not all subtypes. FTD subjects had a larger decline on the MoCA within 13 to 36 months than AD subjects (P=0.02). The results indicate that the MoCA is a useful tool to identify and track progression of CI in FTD. Further, the data informs future research on scoring models for the MoCA to enhance cognitive screening and detection of FTD patients.

    To explore the agreement between the mini-mental state examination (MMSE) and montreal cognitive assessment (MoCA) within community dwelling older patients attending an old age psychiatry service and to derive and test a conversion formula between the two scales. Prospective study of consecutive patients attending outpatient services. Both tests were administered by the same researcher on the same day in random order. The total sample (n = 135) was randomly divided into two groups. One to derive a conversion rule (n = 70), and a second (n = 65) in which this rule was tested. The agreement (Pearson's r) of MMSE and MoCA was 0.86 (P < 0.001), and Lin's concordance correlation coefficient (CCC) was 0.57 (95%CI: 0.45-0.66). In the second sample MoCA scores were converted to MMSE scores according to a conversion rule from the first sample which achieved agreement with the original MMSE scores of 0.89 (Pearson's r, P < 0.001) and CCC of 0.88 (95%CI: 0.82-0.92). Although the two scales overlap considerably, the agreement is modest. The conversion rule derived herein demonstrated promising accuracy and warrants further testing in other populations.

    Cognitive impairment is one of the earliest, most common, and most disabling non-motor symptoms in Parkinson's disease (PD). Thus, routine screening of global cognitive abilities is important for the optimal management of PD patients. Few global cognitive screening instruments have been developed for or validated in PD patients. The Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), and Dementia Rating Scale-2 (DRS-2) have been used extensively for cognitive screening in both clinical and research settings. Determining how to convert the scores between instruments would facilitate the longitudinal assessment of cognition in clinical settings and the comparison and synthesis of cognitive data in multicenter and longitudinal cohort studies. The primary aim of this study was to apply a simple and reliable algorithm for the conversion of MoCA to MMSE scores in PD patients. A secondary aim was to apply this algorithm for the conversion of DRS-2 to both MMSE and MoCA scores. The cognitive performance of a convenience sample of 360 patients with idiopathic PD was assessed by at least two of these cognitive screening instruments. We then developed conversion scores between the MMSE, MoCA, and DRS-2 using equipercentile equating and log-linear smoothing. The conversion score tables reported here enable direct and easy comparison of three routinely used cognitive screening assessments in PD patients. © 2014 International Parkinson and Movement Disorder Society.

  15. Validity of the mini-mental state examination and the montreal cognitive assessment in the prediction of driving test outcome.

    2015-05-01

    To evaluate the effectiveness of two cognitive screening measures, the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA), in predicting driving test outcome for individuals with and without cognitive impairment. Retrospective cohort study. A clinical driving evaluation program at a teaching hospital in the United States. Adult drivers who underwent assessment with the MMSE and MoCA as part of a comprehensive driving evaluation between 2010 and 2014 (N=92). MMSE and MoCA total scores were independent variables. The outcome measure was performance on a standardized road test. A preestablished diagnosis of cognitive impairment enhanced the validity of cognitive screening measures in the identification of at-risk drivers. In individuals with cognitive impairment there was a significant relationship between MoCA score and on-road outcome. Specifically, an individual was 1.36 times as likely to fail the road test with each 1-point decrease in MoCA score. No such relationship was detected in those without a diagnosis of cognitive impairment. For individuals who have not been diagnosed with cognitive impairment, neither the MMSE nor the MoCA can be reliably used as an indicator of driving risk, but for individuals with a preestablished diagnosis of cognitive impairment, the MoCA is a useful tool in this regard. A score on the MoCA of 18 or less should raise concerns about driving safety. © 2015, Copyright the Authors Journal compilation © 2015, The American Geriatrics Society.

  16. Is gentrification all bad? Positive association between gentrification and individual's perceived neighborhood collective efficacy in Montreal, Canada.

    Steinmetz-Wood, Madeleine; Wasfi, Rania; Parker, George; Bornstein, Lisa; Caron, Jean; Kestens, Yan

    2017-07-14

    Collective efficacy has been associated with many health benefits at the neighborhood level. Therefore, understanding why some communities have greater collective efficacy than others is important from a public health perspective. This study examined the relationship between gentrification and collective efficacy, in Montreal Canada. A gentrification index was created using tract level median household income, proportion of the population with a bachelor's degree, average rent, proportion of the population with low income, and proportion of the population aged 30-44. Multilevel linear regression analyses were conducted to measure the association between gentrification and individual level collective efficacy. Gentrification was positively associated with collective efficacy. Gentrifiers (individuals moving into gentrifying neighborhoods) had higher collective efficacy than individuals that lived in a neighborhood that did not gentrify. Perceptions of collective efficacy of the original residents of gentrifying neighborhoods were not significantly different from the perceptions of neighborhood collective efficacy of gentrifiers. Our results indicate that gentrification was positively associated with perceived collective efficacy. This implies that gentrification could have beneficial health effects for individuals living in gentrifying neighborhoods.

  17. Typology of sleep medication users and associated mental health and substance use from a Montreal epidemiological study.

    2014-01-01

    Sleep medication is often reported as one of the most highly used psychotropic drugs in terms of past-year prevalence. Since their use often varies according to the characteristics of individuals, it is important to better understand these particular utilization patterns. The study aims to develop a typology of sleep medication users' characteristics, including their associated mental health and substance use. Residents from the epidemiological area of south-west Montreal, Quebec aged 15 years and older responded to a questionnaire in 2009 and 2011. Among the 1822 people who participated at both T1 and T2, 306 (17%) reported use of medication to help them sleep. These participants were selected for cluster analysis based on five variables related to mental health. The identified clusters were then tested for association with sociodemographic, psychosocial, and service use characteristics. A three-cluster solution emerged: 1) older individuals without mental health problems, drug use or psychotropic medication use; 2) individuals with elevated psychological distress, drug use and low social support, and 3) individuals with mood and anxiety disorders, using services for mental health and taking two or more psychotropic medications. The results establish the significance of problems related to mental health in differentiating sleep medication users. Consideration of these differences may improve the ability of health professionals to provide services that are better suited for patients, including interventions that increase the ability to cope with stress (cluster 2) and more integrated services for those with concurrent disorders (cluster 3).

  18. Montreal Battery of Evaluation of Amusia: Validity evidence and norms for adolescents in Belo Horizonte, Minas Gerais, Brazil

    Marília Nunes-Silva

    Full Text Available ABSTRACT The Montreal Battery of Evaluation of Amusia (MBEA is a battery of tests that assesses six music processing components: scale, contour, interval, rhythm, metric, and music memory. The present study sought to verify the psychometric characteristics of the MBEA in a sample of 150 adolescents aged 14-18 years in the city of Belo Horizonte, Minas Gerais, Brazil, and to develop specific norms for this population. We used statistical procedures that explored the dimensional structure of the MBEA and its items, evaluating their adequacy from empirical data, verifying their reliability, and providing evidence of validity. The results for the difficult levels for each test indicated a trend toward higher scores, corroborating previous studies. From the analysis of the criterion groups, almost all of the items were considered discriminatory. The global score of the MBEA was shown to be valid and reliable (r K-R20=0.896 for assessing the musical ability of normal teenagers. Based on the analysis of the items, we proposed a short version of the MBEA. Further studies with larger samples and amusic individuals are necessary to provide evidence of the validity of the MBEA in the Brazilian milieu. The present study brings to the Brazilian context a tool for diagnosing deficits in musical skills and will serve as a basis for comparisons with single case studies and studies of populations with specific neuropsychological syndromes.

  19. From Osler's Library to the Osler Library of the History of Medicine, McGill University, Montreal: an overview.

    Lyons, Christopher

    2007-01-01

    The Osler Library of the History of Medicine was opened in 1929 at McGill University, Montreal, Canada. Sir William Osler (1849-1919), arguably McGill's and Canada's most famous doctor at the time, had bequeathed his magnificent library of almost 8,000 historical works in medicine and, to a lesser extent, science and literature to the university. Under the 30-year reign of its first librarian, Dr. W W. Francis, the Osler Library became famous for its rare books and for its connection with Sir William. Since the 1950s, however, the library has pursued an active collection development policy for both primary and secondary material that has taken it far beyond Osler's original gift. The library has grown in both the size and scope of its holdings and the services it offers to scholars and students of the history of medicine. These have made the Osler Library a major resource centre for studies in the history of the health sciences. This article looks at the Osler Library today in the hopes of making the range of its collections and services better known to the Canadian and international communities.

  20. The Montreal Cognitive Assessment as a preliminary assessment tool in general psychiatry: Validity of MoCA in psychiatric patients.

    Gierus, J; Mosiołek, A; Koweszko, T; Wnukiewicz, P; Kozyra, O; Szulc, A

    2015-01-01

    The aim of the presented research was to obtain the initial data regarding the validity of Montreal Cognitive Assessment (MoCA) in diagnosing cognitive impairment in psychiatrically hospitalized patients. The results in MoCA obtained from 221 patients were analyzed in terms of proportional participation of patients with particular diagnosis in three result ranges. In 67 patients, additional version of the scale was also used. Comparative analysis of average results in particular diagnostic groups (organically based disorders, disorders due to psychoactive substance use, psychotic disorders, neurotic disorders and personality disorders) was also carried out, as well as an analysis of the scale's accuracy as a diagnostic test in detecting organic disorders. The reliability of the test measured with between tests correlation coefficient rho=0.92 (P=.000). Significant differences between particular diagnoses groups were detected (J-T=13736; P=.000). The cutoff points of 23 turned out to have a satisfactory sensitivity and specificity (0.82 and 0.70, respectively) in diagnosing organically based disorders. The area below the receiver operating characteristic curve (AUC=0.854; P=.000) suggests that MoCA has a satisfactory value as a classifier. The initial data suggest MoCA's high value in prediction of future diagnosis of organically based disorders. The initial results obtained in particular group of diagnoses support construct validity of the method. Copyright © 2015 Elsevier Inc. All rights reserved.

  1. The NAA method at Polytechnique Montreal. An efficient alternative way to use the k0 NAA models

    Chilian, C.; Kennedy, G.

    2014-01-01

    At Ecole Polytechnique Montreal, the philosophy in performing neutron activation analysis (NAA) is long-term and application oriented. Thinking long-term implies a good understanding of the fundamentals of the method, of the samples, of the tools, reactor and detectors, and there must be constant innovation that is experimentally validated with extensive measurements. Application oriented means a NAA method developed to provide users with fast, sensitive, accurate and reliable analyses for various types of materials. This philosophy dictates the manner in which the developments in the areas of NAA software, peak-area calculation, dead-time correction, detection efficiency model, k 0 and Q 0 values, neutron moderation and neutron self-shielding are carried out. This paper presents a survey of the Laboratory’s methodology, reviewing a few of its unique features such as detector efficiency calibration and sample related perturbations of the neutron activation. These features are used as examples to provide the reader with an understanding of the philosophy and the evolution of the NAA method at Ecole Polytechnique. (author)

    Il existe peu d'etudes sur les conceptions touchant les domaines de la biologie, notamment sur les conceptions de la circulation sanguine Nous avons observe egalement l'absence de recherche menee aupres d'eleves de l'ordre collegial sur cette question. Nous avons voulu combler une lacune en menant une recherche sur les conceptions de la circulation sanguine aupres d'eleves de l'ordre collegial. Pour mener cette recherche nous nous sommes inspires d'une methode developpee par Treagust (1988). Le premier niveau de formulation didactique etablit l'architecture du systeme et la fonction nutritive de la circulation. Le second niveau de formulation didactique decrit et relie les parametres de la dynamique de la circulation et leur relation: Pression, Debit et Resistance. Le troisieme niveau de formulation didactique s'interesse au controle de la circulation du sang dans un contexte d'homeostasie qui implique la regulation de la pression arterielle. Nous avons construit un questionnaire en nous guidant sur les niveaux de formulation didactique et l'analyse des entrevues menees aupres de dix-huit eleves, representatifs de la population cible. Ce questionnaire fut administre a un echantillon de 2300 eleves disperses dans six colleges de la region de Montreal. Notre echantillon comprend des eleves inscrits a des programmes de l'ordre collegial en Sciences de la nature et en Techniques de la sante et qui n'ont pas suivi le cours sur la circulation sanguine. Notre analyse des reponses des eleves de notre echantillon aux questions sur le premier niveau de formulation didactique revele que la majorite des eleves considerent que le systeme circulatoire relie les organes les uns aux autres dans un circuit en serie. Notre analyse revele egalement que la majorite des eleves estiment que les nutriments sont extraits du sang par les organes selon un processus de selection base sur les besoins determines par la fonction de l'organe. Ces besoins sont differents selon les organes qui ne

    The first three chapters of these lecture notes are devoted to generalities concerning current algebra. The weak currents are defined, and their main properties given (V-A hypothesis, conserved vector current, selection rules, partially conserved axial current,...). The SU (3) x SU (3) algebra of Gell-Mann is introduced, and the general properties of the non-leptonic weak Hamiltonian are discussed. Chapters 4 to 9 are devoted to some important applications of the algebra. First one proves the Adler- Weisberger formula, in two different ways, by either the infinite momentum frame, or the near-by singularities method. In the others chapters, the latter method is the only one used. The following topics are successively dealt with: semi leptonic decays of K mesons and hyperons, Kroll- Ruderman theorem, non leptonic decays of K mesons and hyperons ( {delta}I = 1/2 rule), low energy theorems concerning processes with emission (or absorption) of a pion or a photon, super-convergence sum rules, and finally, neutrino reactions.

  16. Comparison of spatiotemporal prediction models of daily exposure of individuals to ambient nitrogen dioxide and ozone in Montreal, Canada.

    Buteau, Stephane; Hatzopoulou, Marianne; Crouse, Dan L; Smargiassi, Audrey; Burnett, Richard T; Logan, Travis; Cavellin, Laure Deville; Goldberg, Mark S

    In previous studies investigating the short-term health effects of ambient air pollution the exposure metric that is often used is the daily average across monitors, thus assuming that all individuals have the same daily exposure. Studies that incorporate space-time exposures of individuals are essential to further our understanding of the short-term health effects of ambient air pollution. As part of a longitudinal cohort study of the acute effects of air pollution that incorporated subject-specific information and medical histories of subjects throughout the follow-up, the purpose of this study was to develop and compare different prediction models using data from fixed-site monitors and other monitoring campaigns to estimate daily, spatially-resolved concentrations of ozone (O 3 ) and nitrogen dioxide (NO 2 ) of participants' residences in Montreal, 1991-2002. We used the following methods to predict spatially-resolved daily concentrations of O 3 and NO 2 for each geographic region in Montreal (defined by three-character postal code areas): (1) assigning concentrations from the nearest monitor; (2) spatial interpolation using inverse-distance weighting; (3) back-extrapolation from a land-use regression model from a dense monitoring survey, and; (4) a combination of a land-use and Bayesian maximum entropy model. We used a variety of indices of agreement to compare estimates of exposure assigned from the different methods, notably scatterplots of pairwise predictions, distribution of differences and computation of the absolute agreement intraclass correlation (ICC). For each pairwise prediction, we also produced maps of the ICCs by these regions indicating the spatial variability in the degree of agreement. We found some substantial differences in agreement across pairs of methods in daily mean predicted concentrations of O 3 and NO 2 . On a given day and postal code area the difference in the concentration assigned could be as high as 131ppb for O 3 and 108ppb

  17. Mundialización, acción colectiva e iniciativa local en la reconversión de Montreal

La reconversión lleva a las metrópolis a especializarse en sectores económicos de alto tenor científico-técnico.

  20. Enteric disease episodes and the risk of acquiring a future sexually transmitted infection: a prediction model in Montreal residents.

    Caron, Melissa; Allard, Robert; Bédard, Lucie; Latreille, Jérôme; Buckeridge, David L

    2016-11-01

    The sexual transmission of enteric diseases poses an important public health challenge. We aimed to build a prediction model capable of identifying individuals with a reported enteric disease who could be at risk of acquiring future sexually transmitted infections (STIs). Passive surveillance data on Montreal residents with at least 1 enteric disease report was used to construct the prediction model. Cases were defined as all subjects with at least 1 STI report following their initial enteric disease episode. A final logistic regression prediction model was chosen using forward stepwise selection. The prediction model with the greatest validity included age, sex, residential location, number of STI episodes experienced prior to the first enteric disease episode, type of enteric disease acquired, and an interaction term between age and male sex. This model had an area under the curve of 0.77 and had acceptable calibration. A coordinated public health response to the sexual transmission of enteric diseases requires that a distinction be made between cases of enteric diseases transmitted through sexual activity from those transmitted through contaminated food or water. A prediction model can aid public health officials in identifying individuals who may have a higher risk of sexually acquiring a reportable disease. Once identified, these individuals could receive specialized intervention to prevent future infection. The information produced from a prediction model capable of identifying higher risk individuals can be used to guide efforts in investigating and controlling reported cases of enteric diseases and STIs. © The Author 2016.

  1. Quick screening of cognitive function in Indian multiple sclerosis patients using Montreal cognitive assessment test-short version

    Darshpreet Kaur

    2013-01-01

    Full Text Available Background: Cognitive impairments in multiple sclerosis (MS are now well recognized worldwide, but unfortunately this domain has been less explored in India due to many undermining factors. The aim of this study was to evaluate cognitive impairments in Indian MS patients with visual or upper limb motor problems with the help of short version of Montreal cognitive assessment test (MoCA. Subjects and Methods: Thirty MS patients and 50 matched controls were recruited for the 12 points MoCA task. Receiver operating characteristic curve (ROC analysis was performed to determine optimal sensitivity and specificity of the 12 points MoCA in differentiating cognitively impaired patients and controls. Results: The mean 12 points MoCA scores of the controls and MS patients were 11.56 ± 0.67 and 8.06 ± 1.99, respectively. In our study, the optimal cut-off value for 12 points MoCA to be able to differentiate patients with cognitive impairments from controls is 10/12. Accordingly, 73.3% patients fell below the cut off value. Both the groups did not have significant statistical differences with regard to age and educational years. Conclusion: The 12 points, short version of MoCA, is a useful brief screening tool for quick and early detection of mild cognitive impairments in subjects with MS. It can be administered to patients having visual and motor problems. It is of potential use by primary care physicians, nurses, and other allied health professionals who need a quick screening test. No formal training for administration is required. Financial and time constraints should not limit the use of the proposed instrument.

  2. Social capital and obesity among adults: Longitudinal findings from the Montreal neighborhood networks and healthy aging panel.

    Wu, Yun-Hsuan; Moore, Spencer; Dube, Laurette

    2018-06-01

    Curbing the worldwide increase in obesity requires upstream social interventions that modify the environment in which obesity emerges. Recent studies have suggested that social capital and networks may influence a person's risk of obesity. Yet, few longitudinal studies have assessed whether social capital and networks reduce obesity risk in adult populations. In this study, the data come from three waves (2008, 2010, and 2013) of the Montreal Neighborhood Networks and Health Aging Panel (N=2606). Self-reported height and weight were used to calculate body mass index (BMI) with obesity defined as a BMI>30. Name and position generator instruments captured network measures of social capital, including: (1) upper reachability, (2) range, (3) diversity and (4) the number of kin ties. Questions on generalized trust and participation were used to assess cognitive and structural dimensions of social capital. Separate random effects logistic regression was used to examine the association among social network characteristics, social capital, and obesity. We found the greater the number of kin ties in a person's network, the greater the risk of obesity (OR: 1.33, 95% CI: 1.08-1.62). Adults with higher network diversity (OR: 0.83, 95% CI: 0.72-0.96) and high generalized trust (OR: 0.52, 95% CI: 0.35-0.77) were at a lower the risk of obesity. The current study confirmed that higher network capital and trust were protective against obesity, while having kin ties was not. Disentangling the multidimensional role that social capital plays can lead to more effective interventions to reduce obesity. Copyright © 2017 Elsevier Inc. All rights reserved.

  3. Comparison of montreal cognitive assessment and mini-mental state examination in evaluating cognitive domain deficit following aneurysmal subarachnoid haemorrhage.

    George Kwok Chu Wong

    Full Text Available Cognitive deficits are common after aneurysmal subarachnoid haemorrhage (aSAH, and clinical evaluation is important for their management. Our hypothesis was that the Montreal Cognitive Assessment (MoCa is superior to the Mini-Mental State Examination (MMSE in screening for cognitive domain deficit in aSAH patients.We carried out a prospective observational and diagnostic accuracy study on Hong Kong aSAH patients aged 21 to 75 years who had been admitted within 96 hours of ictus. The domain-specific neuropsychological assessment battery, the MoCA and MMSE were administered 2-4 weeks and 1 year after ictus. A cognitive domain deficit was defined as a cognitive domain z score <-1.65 (below the fifth percentile. Cognitive impairment was defined as two or more cognitive domain deficits. The study is registered at ClinicalTrials.gov of the US National Institutes of Health (NCT01038193.Both the MoCA and the MMSE were successful in differentiating between patients with and without cognitive domain deficits and cognitive impairment at both assessment periods. At 1 year post-ictus, the MoCA produced higher area under the curve scores for cognitive impairment than the MMSE (MoCA, 0.92; 95% CI, 0.83 to 0.97 versus MMSE, 0.77; 95% CI, 0.66 to 0.83, p = 0.009.Cognitive domain deficits and cognitive impairment in patients with aSAH can be screened with the MoCA in both the subacute and chronic phases.

    To compare Montreal Cognitive Assessment (MoCA) and Mini-Mental State Examination (MMSE) global and subscores in classifying cognitive impairment in persons with mild stroke and to explore the relationship between admission and discharge functional status and improvement. Retrospective analysis of data. Acute rehabilitation unit of a large urban university-affiliated hospital. Inpatients with stroke (N=72; mean age, 70y; median time poststroke, 8.5d) and mild neurologic (median National Institutes of Health Stroke Scale score, 4) and cognitive deficits (median MMSE score, 25). Not applicable. Admission cognitive status was assessed by using the MMSE and MoCA. The motor subscale of the FIM instrument (mFIM) and motor relative functional efficiency was used to assess discharge functional status and improvement. The MoCA classified more persons as cognitively impaired than the MMSE (89% vs 63%, respectively; using a cutoff score of 27 on the MMSE and 26 on the MoCA). The MoCA also showed less of a ceiling effect than the MMSE, higher internal reliability (Cronbach α=.78 compared with α=.60), and marginally stronger associations with discharge functional status (r=.40; P<.001) than the MMSE (r=0.30; P<.05). The MoCA visuoexecutive subscore was the strongest predictor of functional status (P=.01) and improvement (P=.02) in global and subscores for both tests. The MoCA may be an important cognitive screening tool for persons with stroke and mild cognitive dysfunction on an acute rehabilitation unit. Lower visuoexecutive subscores may assist in identifying persons at risk for decreased functional gains in self-care and mobility (mFIM) during inpatient rehabilitation. The findings justify further validation studies of the MoCA in persons with subacute stroke. Copyright © 2011 American Congress of Rehabilitation Medicine. Published by Elsevier Inc.

  5. Modeling vehicle operating speed on urban roads in Montreal: a panel mixed ordered probit fractional split model.

    Eluru, Naveen; Chakour, Vincent; Chamberlain, Morgan; Miranda-Moreno, Luis F

    2013-10-01

    Vehicle operating speed measured on roadways is a critical component for a host of analysis in the transportation field including transportation safety, traffic flow modeling, roadway geometric design, vehicle emissions modeling, and road user route decisions. The current research effort contributes to the literature on examining vehicle speed on urban roads methodologically and substantively. In terms of methodology, we formulate a new econometric model framework for examining speed profiles. The proposed model is an ordered response formulation of a fractional split model. The ordered nature of the speed variable allows us to propose an ordered variant of the fractional split model in the literature. The proposed formulation allows us to model the proportion of vehicles traveling in each speed interval for the entire segment of roadway. We extend the model to allow the influence of exogenous variables to vary across the population. Further, we develop a panel mixed version of the fractional split model to account for the influence of site-specific unobserved effects. The paper contributes substantively by estimating the proposed model using a unique dataset from Montreal consisting of weekly speed data (collected in hourly intervals) for about 50 local roads and 70 arterial roads. We estimate separate models for local roads and arterial roads. The model estimation exercise considers a whole host of variables including geometric design attributes, roadway attributes, traffic characteristics and environmental factors. The model results highlight the role of various street characteristics including number of lanes, presence of parking, presence of sidewalks, vertical grade, and bicycle route on vehicle speed proportions. The results also highlight the presence of site-specific unobserved effects influencing the speed distribution. The parameters from the modeling exercise are validated using a hold-out sample not considered for model estimation. The results indicate

  6. Validity of the Montreal Cognitive Assessment Screener in Adolescents and Young Adults With and Without Congenital Heart Disease.

    Pike, Nancy A; Poulsen, Marie K; Woo, Mary A

    Cognitive deficits are common, long-term sequelae in children and adolescents with congenital heart disease (CHD) who have undergone surgical palliation. However, there is a lack of a validated brief cognitive screening tool appropriate for the outpatient setting for adolescents with CHD. One candidate instrument is the Montreal Cognitive Assessment (MoCA) questionnaire. The purpose of the research was to validate scores from the MoCA against the General Memory Index (GMI) of the Wide Range Assessment of Memory and Learning, 2nd Edition (WRAML2), a widely accepted measure of cognition/memory, in adolescents and young adults with CHD. We administered the MoCA and the WRAML2 to 156 adolescents and young adults ages 14-21 (80 youth with CHD and 76 healthy controls who were gender and age matched). Spearman's rank order correlations were used to assess concurrent validity. To assess construct validity, the Mann-Whitney U test was used to compare differences in scores in youth with CHD and the healthy control group. Receiver operating characteristic curves were created and area under the curve, sensitivity, specificity, positive predictive value, and negative predictive value were also calculated. The MoCA median scores in the CHD versus healthy controls were (23, range 15-29 vs. 28, range 22-30; p young adults aged 14-21 with CHD when a cutoff score of 26 is used to differentiate youth with and without significant cognitive impairment. Future studies are needed in other adolescent disease groups with known cognitive deficits and healthy populations to explore the generalizability of validity of MoCA scores in adolescents and young adults.

    This article examines the story of the Assistance maternelle de Montreal, an organization founded in 1912 by a group of bourgeois catholic women to provide material assistance and free medical services to poor pregnant mothers of the city. I want to show that even if the timid intervention of the Quebec state allowed the AM to survive during the almost 50 years, the rise of the experts in the health field--a phenomenon to which the AM has largely contributed--and in the philanthropic sector led to the marginalization of the female volunteers within the very institution they had created.

    Full Text Available Osteoporose ist in hohem Maß genetisch determiniert. Neue Wege der molekularbiologischen Forschung haben sich in den letzten Jahren auf diesem Gebiet etabliert. "Gene mapping" mit polymorphen genetischen Markern auf der Suche nach Phänotyp-assoziierten Genen ist ein aufwendiges, aber vielversprechendes Verfahren und wird durch die Erkenntnisse des Human Genome Projects beschleunigt. So wurde jüngst u. a. das Low-density Lipoprotein 5-Gen als wichtig für den Knochenstoffwechsel identifiziert. Kandidaten-gene wie Hormonrezeptor-, Cytokin- oder Kollagen-Gene werden hinsichtlich ihrer Gen-Gen- und Gen-Umwelt- Interaktionen untersucht und erlauben neue funktionelle Einsichten in Erkrankungen des Knochenstoffwechsels. Mutationen der Kollagen-Gene sind bei einigen seltenen Erkrankungen, wie dem Osteoporose-Pseudogliom-Syndrom oder der Osteogenesis imperfecta gefunden worden, könnten aber auch für häufige Varianten von Bindegewebsstörungen wie der congenitalen Hüftdysplasie verantwortlich sein, die etwa 10 % der weiblichen kaukasischen Bevölkerung in unterschiedlichem Ausmaß betrifft. Osteoporose am Schenkelhals und erhöhte Gelenkslaxizität sowie andere generalisierte Veränderungen des Knochen- und Kollagenstoffwechsels können hier möglicherweise ebenfalls durch Störungen des Kollagen I alpha 1-Gens erklärt werden. In Summe können wir zahlreiche neue Einsichten in die Pathophysiologie des Skelettsystems erwarten, die uns auch neue Zugangswege für Diagnostik und Therapie unserer Patienten ermöglichen werden.

  3. Music Perception by Cochlear Implant and Normal Hearing Listeners as Measured by the Montreal Battery for Evaluation of Amusia

    2009-01-01

    Objectives The purpose of this study was to explore the utility/possibility of using the Montreal Battery for Evaluation of Amusia (MBEA) test (Peretz, Champod, & Hyde, 2003) to assess the music perception abilities of cochlear implant (CI) users. Design The MBEA was used to measure six different aspects of music perception (Scale, Contour, Interval, Rhythm, Meter, and Melody Memory) by CI users and normal hearing (NH) listeners presented with stimuli processed via CI simulations. The spectral resolution (number of channels) was varied in the CI simulations to determine: (a) the number of channels (4, 6, 8, 12, 16) needed to achieve the highest levels of music perception and (b) the number of channels needed to produce levels of music perception performance comparable to that of CI users. Results CI users and NH listeners performed higher on temporal-based tests (Rhythm and Meter) than on pitch-based tests (Scale, Contour, and Interval) – a finding that is consistent with previous research studies. The CI users' scores on pitch-based tests were near chance. The CI users' (but not NH listeners') scores for the Memory test, a test that incorporates an integration of both temporal-based and pitch-based aspects of music, were significantly higher than the scores obtained for the pitch-based Scale test and significantly lower than the temporal-based Rhythm and Meter tests. The data from NH listeners indicated that 16 channels of stimulation did not provide the highest music perception scores and performance was as good as that obtained with 12 channels. This outcome is consistent with other studies showing that NH listeners listening to vocoded speech are not able to utilize effectively F0 cues present in the envelopes, even when the stimuli are processed with a large number (16) of channels. The CI user data appear to most closely match with the 4- and 6- channel NH listener conditions for the pitch-based tasks. Conclusions Consistent with previous studies, both CI

  5. Lung cancer risk among workers in the construction industry: results from two case-control studies in Montreal.

    2015-09-22

    Given the large number of workers in the construction industry, it is important to derive accurate and valid estimates of cancer risk, and in particular lung cancer risk. In most previous studies, risks among construction workers were compared with general populations including blue and white collar workers. The main objectives of this study were to assess whether construction workers experience excess lung cancer risk, and whether exposure to selected construction industry exposures carries excess risks. We wished to address these objectives within the sub-population of blue collar workers. Two case-control studies were conducted in Montreal. Combined, they included 1593 lung cancer cases and 1427 controls, of whom 1304 cases and 1081 controls had been blue collar workers. Detailed lifetime job histories were obtained and translated by experts into histories of exposure to chemical agents. The two key analyses were to estimate odds ratio (OR) estimates of lung cancer risk: a) for all blue-collar construction workers compared with other blue-collar workers, and b) for construction workers exposed to each of 20 exposure agents found in the construction industry compared with construction workers unexposed to those agents. All analyses were conducted using unconditional logistic regression adjusted for socio-demographic factors and smoking history. The OR for all construction workers combined was 1.11 (95 % CI: 0.90-1.38), based on 381 blue collar construction workers. Analyses of specific exposures were hampered by small numbers and imprecise estimates. While none of 20 occupational agents examined was significantly associated with lung cancer, the following agents manifested non-significantly elevated ORs: asbestos, silica, Portland cement, soil dust, calcium oxide and calcium sulfate. Compared with other blue collar workers, there was only a slight increased risk of lung cancer for subjects who ever held an occupation in the construction industry. The analyses of

    Senouf, J

    2000-01-01

    Les grands contrats de travaux génèrent un grand nombre de commandes (OSVC) passées par un grand nombre de responsables techniques. Ils sont généralement basés sur des bordereaux de prix associés à un éventail de conditions économiques adaptées aux besoins complexes et variés des multiples utilisateurs du CERN nécessitant des calculs sophistiqués. L'administration des commandes, le suivi des travaux et de la facturation doivent répondre aux besoins de tous les acteurs. Les responsables techniques doivent jouir de la plus large indépendance administrative dans le respect des règlements CERN et des conditions contractuelles. Le contrôle des métrés et décomptes doit être rigoureux et d'une traçabilité complète. L'utilisation des bases de données Oracle a déjà permis l'intégration des données administratives et techniques.

  8. La production mondiale des vins

    Pierre GALET

    1970-06-01

    On sait peu de choses précises sur l'origine de la culture de la vigne en Gaule. Il est probable qu'il existait des lambrusques sauvages dans les forêts et les sous-bois dont les habitants récoltaient les raisins pour les consommer à l'état frais et peut-être en tiraient-ils aussi une boisson fermentée comme ils le faisaient pour l'orge ou pour le miel (hydromel. Il est vraisemblable aussi que les navigateurs phocéens, venus commercer sur les rivages de la Méditerranée, apportèrent du vin aux gaulois, leur apprirent à tailler la vigne et finalement, en établissant des comptoirs, amenèrent des boutures de vignes de leur propre pays. On sait que les gaulois apprécièrent très vite le vin et ce fut une des raisons de leurs invasion de la Toscane pour y consommer sur place cette « boisson magique ». Plus tard avec l'occupation romaine la culture de la vigne s'étendit dans toute la province narbonnaise, dans la vallée du Rhône jusqu'aux portes de Lyon, puis en Aquitaine. A leur tour les romains se mirent à apprécier les vins gaulois, de qualité supérieure à ceux récoltés en Italie sur les Hautains. A l'aide de la navigation fluviale sur le Rhône les vins gagnèrent Rome, ainsi que ceux embarqués dans les petits ports du rivage méditerranéen. Puis au cours des siècles et grâce notamment aux religieux catholiques la vigne se répandit dans toutes les provinces. A la veille de la Révolution, en 1788, on estimait la superficie cultivée à 1.567.000 hectares, produisant 27 millions d'hectolitres. Au cours du XIXe siècle, les plantations augmentèrent en raison des facilités de transport que permettait l'établissement des lignes de chemin de fer. Le ravitaillement des grandes villes fut assuré par la création d'un important vignoble dans le Midi. En 1875, la superficie cultivée dépassait 2,4 millions d'hectares et la France produisit 83,8 millions d'hectolitres, record absolu qui ne fut jamais plus atteint depuis. La crise phyllox

  9. La territorialisation des politiques environnementales

    Amédée Mollard

    2010-10-01

    Full Text Available Le point de départ de cet article est la grande variabilité de la pollution nitrique diffuse de l’eau due à l’agriculture. Celle-ci dépend en particulier du climat, des types de sol et des systèmes de production agricole. Nos recherches réalisées de façon interdisciplinaire à partir de deux sites différents en France, montrent que cette hétérogénéité spatio-temporelle conditionne les pratiques agricoles mises en œuvre pour réduire la pollution au niveau de la norme admise. De ce fait, les pratiques les plus « coût-efficaces » diffèrent d’un territoire à l’autre, en fonction des caractéristiques locales. Ces résultats mettent donc en évidence une efficacité potentielle d’une territorialisation des politiques publiques. En théorie, de telles politiques sont considérées comme optimales par les économistes, car elles incitent les agents à moduler leurs efforts en fonction de la sensibilité du milieu. Mais, selon les études empiriques, cet avantage serait annulé par un coût élevé de mise en œuvre, de contrôle et de surveillance. Pour maintenir leur avantage sur des politiques uniformes, les politiques territorialisées devraient être mises en œuvre à un niveau spatial optimal. Un tel niveau devrait au minimum atteindre un compromis entre l’économie réalisée grâce à une modulation adaptée aux conditions locales et les sur-coûts dus à la décentralisation des solutions mises en œuvre. Cet article analyse la pertinence d’une prise en compte de ces spécificités par des politiques territorialisées. L’efficacité d’une régulation différenciée de la pollution nitrique est étudiée ici en évaluant l’importance de la variabilité spatiale des paramètres physiques et des coûts de la territorialisation.The paper starts with the wide variability of nonpoint water nitrogenous pollution generated by agriculture. This variability depends especially on climate, soil types and farming

  17. Global warming potential estimates for the C1-C3 hydrochlorofluorocarbons (HCFCs) included in the Kigali Amendment to the Montreal Protocol

    Papanastasiou, Dimitrios K.; Beltrone, Allison; Marshall, Paul; Burkholder, James B.

    2018-05-01

    Hydrochlorofluorocarbons (HCFCs) are ozone depleting substances and potent greenhouse gases that are controlled under the Montreal Protocol. However, the majority of the 274 HCFCs included in Annex C of the protocol do not have reported global warming potentials (GWPs) which are used to guide the phaseout of HCFCs and the future phase down of hydrofluorocarbons (HFCs). In this study, GWPs for all C1-C3 HCFCs included in Annex C are reported based on estimated atmospheric lifetimes and theoretical methods used to calculate infrared absorption spectra. Atmospheric lifetimes were estimated from a structure activity relationship (SAR) for OH radical reactivity and estimated O(1D) reactivity and UV photolysis loss processes. The C1-C3 HCFCs display a wide range of lifetimes (0.3 to 62 years) and GWPs (5 to 5330, 100-year time horizon) dependent on their molecular structure and the H-atom content of the individual HCFC. The results from this study provide estimated policy-relevant GWP metrics for the HCFCs included in the Montreal Protocol in the absence of experimentally derived metrics.

  18. Captive breeding of the barndoor skate (Dipturus laevis) at the Montreal Biodome, with comparison notes on two other captive-bred skate species.

    Parent, Serge; Pépin, Serge; Genet, Jean-Pierre; Misserey, Laurent; Rojas, Salvador

    2008-03-01

    In 1997, the Montreal Biodome obtained five barndoor skates (Dipturus laevis) from the waters off Boston, Massachusetts. Six years later, those specimens began reproducing, and the first egg case was collected in November 2003. Since then, 73 hatchlings have been born and raised. Egg cases were observed year round, and annual fecundity was measured for the first time: one female laid 69 eggs in 2005, 85 in 2006 and 115 in 2007. Egg incubation was longer than believed previously, ranging from 342 to 494 days. Hatching occurred throughout the year. Hatchlings averaged 193 mm total length and 128 mm disk width and weighed 32 g. They were fed krill and diced fish. All but one survived the first month. A photo identification system was useful in recognizing two groups of 10 specimens during their first year, and transponders could be inserted in the wing muscles of 1-year-old skates. Total lengths at birth and at age 2 were similar to the data reported from the wild, suggesting a similar growth pattern in captivity. The reproduction characteristics of the barndoor skate were compared with those of two other skate species currently bred at the Montreal Biodome, the winter skate (Leucoraja ocellata) and the thorny skate (Amblyraja radiata).

    Gohlke, B. [IMI Norgren Herion Fluidtronic GmbH und Co. KG, Fellbach (Germany)

    2003-09-01

    The European Parliament and European Council have enacted special codes in order to implement uniform conditions in all countries of the European Community. The manufacturers of technical and commercial products are obliged to adhere to these codes. Harmonized standards, which are to be used as a tool for the implementation of the codes, are embedded at another level of the overall 'European reference literature'. Two EC codes, in particular, are definitive for fluids engineering: On the one hand, the EC Machinery Code, 98/37/EC and, on the other hand, the EC Pressurized Equipment Code, 97/23/EC. These EC codes cover, inter alia, machinery and chemical process-engineering plants, and conventional power generating plants. Norgren-Herion, a manufacturer of fluid engineering components, perceived a necessity for positioning its control valves in the scope of applicability of the EC codes. This article describes experience with the EC codes from the control valve manufacturer's point of view and examines the various qualification procedures for control valves. (orig.)

     Le continent européen constitue le principal foyer de la culture de la vigne. Il vient en tête, non seulement par l'importance de la superficie cultivée, mais également par le volume global de la récolte et par la qualité des produits qui y sont récoltés : vins fins rouges, rosés et blancs, vins mousseux, vins de dessert ou vins généreux, eaux-de-vie, raisins de table frais et raisins secs. Les pays européens sont également les principaux consommateurs de vins du monde et la majeure partie des échanges commerciaux se font vers l'Europe ou partent de ce continent.

    Full Text Available La culture de la vigne en Autriche remonterait à l'occupation romaine, les premières plantations ayant été faites par les légions romaines de l'empereur Probus, dans la seconde moitié du IIIe siècle (Probus était né à Sirmium près du Danube et il favorisa l'extension des vignobles dans cette région pour approvisionner ses armées. Après la chute de l'empire romain et les invasions des Awares, on doit à Charlemagne le renouveau de la culture de la vigne, notamment dans la Wachau, en Basse- Autriche. Puis plus tard, à chaque avance de la colonisation, les vignes se répandirent sur les bords du Danube et dans les vallées latérales, l'extension étant favorisée par les communautés religieuses catholiques qui devinrent propriétaires de grands vignobles. La navigation sur le fleuve fut également un facteur favorable pour la culture de la vigne. Au XVIe siècle, apogée des cultures, le vin se vendait jusqu'en Pologne et dans les Etats Baltes.

  19. Impact de la preparation des anodes crues et des conditions de cuisson sur la fissuration dans des anodes denses

    Amrani, Salah

    La fabrication de l'aluminium est realisee dans une cellule d'electrolyse, et cette operation utilise des anodes en carbone. L'evaluation de la qualite de ces anodes reste indispensable avant leur utilisation. La presence des fissures dans les anodes provoque une perturbation du procede l'electrolyse et une diminution de sa performance. Ce projet a ete entrepris pour determiner l'impact des differents parametres de procedes de fabrication des anodes sur la fissuration des anodes denses. Ces parametres incluent ceux de la fabrication des anodes crues, des proprietes des matieres premieres et de la cuisson. Une recherche bibliographique a ete effectuee sur tous les aspects de la fissuration des anodes en carbone pour compiler les travaux anterieurs. Une methodologie detaillee a ete mise au point pour faciliter le deroulement des travaux et atteindre les objectifs vises. La majorite de ce document est reservee pour la discussion des resultats obtenus au laboratoire de l'UQAC et au niveau industriel. Concernant les etudes realisees a l'UQAC, une partie des travaux experimentaux est reservee a la recherche des differents mecanismes de fissuration dans les anodes denses utilisees dans l'industrie d'aluminium. L'approche etait d'abord basee sur la caracterisation qualitative du mecanisme de la fissuration en surface et en profondeur. Puis, une caracterisation quantitative a ete realisee pour la determination de la distribution de la largeur de la fissure sur toute sa longueur, ainsi que le pourcentage de sa surface par rapport a la surface totale de l'echantillon. Cette etude a ete realisee par le biais de la technique d'analyse d'image utilisee pour caracteriser la fissuration d'un echantillon d'anode cuite. L'analyse surfacique et en profondeur de cet echantillon a permis de voir clairement la formation des fissures sur une grande partie de la surface analysee. L'autre partie des travaux est basee sur la caracterisation des defauts dans des echantillons d'anodes crues

  20. Using XML to encode TMA DES metadata

    Oliver Lyttleton

    2011-01-01

    Full Text Available Background: The Tissue Microarray Data Exchange Specification (TMA DES is an XML specification for encoding TMA experiment data. While TMA DES data is encoded in XML, the files that describe its syntax, structure, and semantics are not. The DTD format is used to describe the syntax and structure of TMA DES, and the ISO 11179 format is used to define the semantics of TMA DES. However, XML Schema can be used in place of DTDs, and another XML encoded format, RDF, can be used in place of ISO 11179. Encoding all TMA DES data and metadata in XML would simplify the development and usage of programs which validate and parse TMA DES data. XML Schema has advantages over DTDs such as support for data types, and a more powerful means of specifying constraints on data values. An advantage of RDF encoded in XML over ISO 11179 is that XML defines rules for encoding data, whereas ISO 11179 does not. Materials and Methods: We created an XML Schema version of the TMA DES DTD. We wrote a program that converted ISO 11179 definitions to RDF encoded in XML, and used it to convert the TMA DES ISO 11179 definitions to RDF. Results: We validated a sample TMA DES XML file that was supplied with the publication that originally specified TMA DES using our XML Schema. We successfully validated the RDF produced by our ISO 11179 converter with the W3C RDF validation service. Conclusions: All TMA DES data could be encoded using XML, which simplifies its processing. XML Schema allows datatypes and valid value ranges to be specified for CDEs, which enables a wider range of error checking to be performed using XML Schemas than could be performed using DTDs.

  3. Review of plants to mitigate particulate matter, ozone as well as nitrogen dioxide air pollutants and applicable recommendations for green roofs in Montreal, Quebec.

    Gourdji, Shannon

    2018-05-28

    In urbanized regions with expansive impervious surfaces and often low vegetation cover, air pollution due to motor vehicles and other combustion sources, is a problem. The poor air quality days in Montreal, Quebec are mainly due to fine particulate matter and ozone. Businesses using wood ovens are a source of particulates. Careful vegetation selection and increased green roof usage can improve air quality. This paper reviews different green roofs and the capability of plants in particulate matter (PM), ozone (O 3 ) as well as nitrogen dioxide (NO 2 ) level reductions. Both the recommended green roof category and plants to reduce these pollutants in Montreal's zone 5 hardiness region are provided. Green roofs with larger vegetation including shrubs and trees, or intensive green roofs, remove air pollutants to a greater extent and are advisable to implement on existing, retrofitted or new buildings. PM is most effectively captured by pines. The small Pinus strobus 'Nana', Pinus mugho var. pumilio, Pinus mugho 'Slowmound' and Pinus pumila 'Dwarf Blue' are good candidates for intensive green roofs. Drought tolerant, deciduous broadleaved trees with low biogenic volatile organic compound emissions including Japanese Maple or Acer palmatum 'Shaina' and 'Mikawa-Yatsubusa' are options to reduce O 3 levels. Magnolias are tolerant to NO 2 and it is important in their metabolic pathways. The small cold-tolerant Magnolia 'Genie' is a good option to remove NO 2 in urban settings and to indirectly reduce O 3 formation. Given the emissions by Montreal businesses' wood ovens, calculations performed based on their respective complex roof areas obtained via Google Earth Pro indicates 88% Pinus mugho var. pumilio roof coverage can annually remove 92.37 kg of PM 10 of which 35.10 kg is PM 2.5 . The removal rates are 4.00 g/m 2 and 1.52 g/m 2 for PM 10 and PM 2.5 , respectively. This paper provides insight to addressing air pollution through urban rooftop greening. Copyright

  4. Accessibility to health care facilities in Montreal Island: an application of relative accessibility indicators from the perspective of senior and non-senior residents

    2010-10-01

    Full Text Available Abstract Background Geographical access to health care facilities is known to influence health services usage. As societies age, accessibility to health care becomes an increasingly acute public health concern. It is known that seniors tend to have lower mobility levels, and it is possible that this may negatively affect their ability to reach facilities and services. Therefore, it becomes important to examine the mobility situation of seniors vis-a-vis the spatial distribution of health care facilities, to identify areas where accessibility is low and interventions may be required. Methods Accessibility is implemented using a cumulative opportunities measure. Instead of assuming a fixed bandwidth (i.e. a distance threshold for measuring accessibility, in this paper the bandwidth is defined using model-based estimates of average trip length. Average trip length is an all-purpose indicator of individual mobility and geographical reach. Adoption of a spatial modelling approach allows us to tailor these estimates of travel behaviour to specific locations and person profiles. Replacing a fixed bandwidth with these estimates permits us to calculate customized location- and person-based accessibility measures that allow inter-personal as well as geographical comparisons. Data The case study is Montreal Island. Geo-coded travel behaviour data, specifically average trip length, and relevant traveller's attributes are obtained from the Montreal Household Travel Survey. These data are complemented with information from the Census. Health care facilities, also geo-coded, are extracted from a comprehensive business point database. Health care facilities are selected based on Standard Industrial Classification codes 8011-21 (Medical Doctors and Dentists. Results Model-based estimates of average trip length show that travel behaviour varies widely across space. With the exception of seniors in the downtown area, older residents of Montreal Island tend to be

    2002-03-01

    Full Text Available Il existe dans les bases de données publiques une énorme quantité de séquences d’ADN dérivées de plantes, et notamment la séquence complète du génome d’Arabidopsis thaliana, une plante modèle pour les oléagineux, proche parente du colza. Ces données constituent une ressource importante non seulement pour la compréhension de métabolisme lipidique et de sa régulation, mais aussi pour la sélection et le développement de variétés nouvelles d’oléagineux produisant davantage d’huiles ou des huiles de composition nouvelle. Cette abondance de séquences peut être exploitée, en utilisant les recherches d’homologies, pour identifier les gènes, pour obtenir des informations sur leur fonction, comme pour repérer des gènes candidats codant des fonctions nouvelles. L’analyse de ces bases de données a révélé que la majeure partie des gènes codant des enzymes impliquées dans le métabolisme lipidique appartient à des petites familles multigéniques, reflétant la diversification des fonctions des isoformes. Une analyse du catalogue des ADNc séquencés en aveugle reflète les niveaux d’expression des différents gènes et fournit un aperçu des régulations des flux au travers des voies métaboliques conduisant à la biosynthèse des lipides de réserve. La disponibilité de mutants et de lignées transgéniques d’Arabidopsis et le développement de puces à ADN qui permettent l’analyse simultanée de plusieurs milliers de gènes conduiront à une meilleure compréhension des facteurs qui régulent le métabolisme des huiles dans les graines. Une telle connaissance facilitera la manipulation de la composition des huiles et des quantités produites dans les graines.

    2016-01-01

    Full Text Available The data encryption standard is a pioneering and farsighted standard which helped to set a new paradigm for encryption standards. But now DES is considered to be insecure for some application. Asymmetric mask protected DES is an advanced encryption method for effectively protecting the advanced DES. There are still probabilities to improve its security. This paper propose a method, which introduce a RSA key generation scheme in mask protected DES instead of plain key, which result in enhancement in the security of present asymmetric mask protected DES. We further propose a Vedic mathematical method of RSA implementation which reduce the complexity of computation in RSA block thereby resulting in reduced delay (four timesthat improves the performance of overall system. The software implementation was performed using Xilinx 13.2 and Model-Sim was used for the simulation environment.

Le diagnostic peut être suspecté cliniquement dans un contexte évocateur, mais il ne peut être certifié qu’au stade histologique. PATIENTS ET METHODES:Cinq cas de tuberculose des amygdales palatine ont été diagnostiqués sur une période de 5 ans et inclus dans une étude rétrospective. Nous avons recensé trois hommes et deux femmes (âge moyen de 28 ans. La dysphagie haute était le maître symptôme. L’examen a objectivé une hypertrophie amygdalienne chez tous les patients avec des ulcérations chez trois d’entre eux. Une biopsie a été effectuée chez trois patients et une amygdalectomie a été réalisée chez les deux autres. L’étude anatomopathologique a posé le diagnostic chez tous les patients. Un traitement médical antituberculeux selon un régime court allant de 6 à 9 mois a été instauré. Dans tous les cas, l’évolution à long terme a été favorable avec un recul moyen de 13 mois. CONCLUSION: La tuberculose amygdalienne est rare. Son diagnostic repose essentiellement sur le résultat anatomopathologique de la biopsie où de l’amygdalectomie. L’évolution sous traitement anti-bacillaire est souvent favorable, la récidive est exceptionnelle.

    Gay, bisexual, and other men who have sex with men (MSM) have adapted their sexual practices over the course of the HIV/AIDS epidemic based on available data and knowledge about HIV. This study sought to identify and compare patterns in condom use among gay, bisexual, and other MSM who were tested for HIV at a community-based testing site in Montreal, Canada. Results showed that while study participants use condoms to a certain extent with HIV-positive partners and partners of unknown HIV status, they also make use of various other strategies such as adjusting to a partner's presumed or known HIV status and viral load, avoiding certain types of partners, taking PEP, and getting tested for HIV. These findings suggest that MSM who use condoms less systematically are not necessarily taking fewer precautions but may instead be combining or replacing condom use with other approaches to risk reduction.

    The aim of the present study is to examine the accuracy of the Brazilian versions of the Montreal Cognitive Assessment (MoCA) and the Addenbrooke's Cognitive Examination-Revised (ACE-R) to screen for mild cognitive impairment (PDMCI) and dementia (PDD) in patients with Parkinson's disease (PD). Both scales were administered to a final convenience sample of 79 patients with PD. Patients were evaluated by a neurologist, a psychiatrist and a neuropsychologist using UPDRS, Hoehn and Yahr and Schwab and England scales, global deterioration scale, a psychiatric structured interview, Mattis Dementia Rating Scale and other cognitive tests. There were 32 patients with PDMCI and 17 patients with PDD. The MoCA and the ACE-R were able to discriminate patients with PDD from the others. Both scales showed to be useful to screen for dementia but not for mild cognitive impairment in patients with PD.

  18. Effects of diurnal variations in temperature on non-accidental mortality among the elderly population of Montreal, Québec, 1984-2007.

    2014-07-01

    The association between ambient temperature and mortality has been studied extensively. Recent data suggest an independent role of diurnal temperature variations in increasing daily mortality. Elderly adults-a growing subgroup of the population in developed countries-may be more susceptible to the effects of temperature variations. The aim of this study was to determine whether variations in diurnal temperature were associated with daily non-accidental mortality among residents of Montreal, Québec, who were 65 years of age and over during the period between 1984 and 2007. We used distributed lag non-linear Poisson models constrained over a 30-day lag period, adjusted for temporal trends, mean daily temperature, and mean daily concentrations of nitrogen dioxide and ozone to estimate changes in daily mortality with diurnal temperature. We found, over the 30 day lag period, a cumulative increase in daily mortality of 5.12% [95% confidence interval (CI): 0.02-10.49%] for a change from 5.9 °C to 11.1 °C (25th to 75th percentiles) in diurnal temperature, and a 11.27% (95%CI: 2.08-21.29%) increase in mortality associated with an increase of diurnal temperature from 11.1 to 17.5 °C (75th to 99th percentiles). The results were relatively robust to adjustment for daily mean temperature. We found that, in Montreal, diurnal variations in temperature are associated with a small increase in non-accidental mortality among the elderly population. More studies are needed in different geographical locations to confirm this effect.

  1. Membrane fluidization by alcohols inhibits DesK-DesR signalling in Bacillus subtilis.

    After cold shock, the Bacillus subtilis desaturase Des introduces double bonds into the fatty acids of existing membrane phospholipids. The synthesis of Des is regulated exclusively by the two-component system DesK/DesR; DesK serves as a sensor of the state of the membrane and triggers Des synthesis after a decrease in membrane fluidity. The aim of our work is to investigate the biophysical changes in the membrane that are able to affect the DesK signalling state. Using linear alcohols (ethanol, propanol, butanol, hexanol, octanol) and benzyl alcohol, we were able to suppress Des synthesis after a temperature downshift. The changes in the biophysical properties of the membrane caused by alcohol addition were followed using membrane fluorescent probes and differential scanning calorimetry. We found that the membrane fluidization induced by alcohols was reflected in an increased hydration at the lipid-water interface. This is associated with a decrease in DesK activity. The addition of alcohol mimics a temperature increase, which can be measured isothermically by fluorescence anisotropy. The effect of alcohols on the membrane periphery is in line with the concept of the mechanism by which two hydrophilic motifs located at opposite ends of the transmembrane region of DesK, which work as a molecular caliper, sense temperature-dependent variations in membrane properties.

    Full Text Available This article examines regional differences based on students’ participation, sociodemographic profiles, behaviors and learning outcomes. To do this, students were followed in a course offered by “École des hautes études commerciales” (HEC of Montreal in their MOOC initiative called EDUlib. The analysis was performed using the platform traces (accessed resources, number of visits, activities in the environment and responses to self-report questionnaire. Regionals differences were observed, which seem related to the country’s development index. The results suggest some difficulty in reaching these students, despite the fact that participants who register in order to promote their development seem to struggle to pass the course.

  11. Contrôle des Circuits Auxiliaires des PFW (arrêt machines 2002/2003)

    Ottaviani, J

    2003-01-01

    Les PFW sont des nappes polaires installées sur les pôles des aimants du PS. Elles sont au nombre de 4 par unité d aimant et constituées d un circuit principal (dans lequel circule le courant désiré selon le cycle magnétique utilisé) et de circuits auxiliaires. Les circuits auxiliaires sont des enroulements de correction (boucles de tour et pick-up brasés sur les enroulements). Pendant la variation du champ magnétique de l aimant PS, on utilise des tensions induites dans ces circuits auxiliaires pour corriger les erreurs de champ dues aux courants de Foucault dans la chambre à vide. Chaque année, pendant l arrêt machine, on vérifie si les caractéristiques des circuits auxiliaires correspondent aux normes (mesures des résistances des boucles de tours, résistances entre pick-up et isolation des circuits) afin de faire un suivi. Les 404 PFW sont ainsi vérifiées. Dans cette note, on ne relèvera que les PFW ayant des défauts (valeurs hors tolérances, boucles ouvertes ou en court-circuit, déf...

  13. Les lexiques des jeunes dans les discours écrits des blogs : pour une approche descriptive

    Lorenz Paulina

    2014-07-01

    Full Text Available S’il ne faut pas confondre ce qui est appelé communément « langage SMS » et « langage des jeunes », nous avancerons toutefois que les pratiques langagières écrites des jeunes sur les supports modernes de communication, et notamment dans les blogs, présentent des particularités encore peu étudiées. Les traits observables les plus saillants sont ceux de la morphologie graphique, mais il n’en reste pas moins que certains jeunes utilisent des lexiques particuliers dans les blogs qui méritent une attention particulière. Nous nous proposons donc d’étudier les différents lexiques utilisés par des jeunes de 12 à 22 ans dans les blogs de la plateforme skyrock.com aux niveaux de sa diversité, de ses usages sémantiques variable d’un scripteur à l’autre pour un même mot, et de ses particularités morphosyntaxiques. En effet, nous observerons des lexiques divers allant des lexiques perçus comme relevant des cités à des lexiques perçus comme étant « branchés-jeunes », ou encore à des lexiques propres aux supports modernes de communication. Ainsi, nous analyserons des lexiques variés dans leurs usages écrits tels que bolos, bédave, gérer, ouf, tigen, ou encore des lexiques empruntés tels que mouv, full, etc., ainsi que des emplois particuliers de séquences autonomes comme lol. Quelques questions périphériques complèteront notre analyse telle que celles qui concerne l’influence des usages lexicaux entre pairs et le savoir partagé, la distinction de différentes communautés en fonction des lexiques utilisés, ou encore la variabilité des représentations graphiques d’un même mot.

    Full Text Available Je voudrais parler ici des recherches que j'ai effectuées dans le cadre d'un programme de recherches de l'Organisation australienne de recherches (C.S.I.R.O.. Ce sont des recherches sur la structure, la composition chimique et le rôle de la cire cuticulaire des grains de raisins et des feuilles. Ces recherches ont été effectuées principalement lors de l'étude des problèmes relatifs au séchage des raisins pour la production des raisins. Cependant, l'importance de la cire cuticulaire ne se limite pas seulement au séchage des raisins, car elle concerne aussi l'œnologie et les problèmes de la conservation des raisins de table.

    Résumé Religion et guérisseurs traditionnels occupent encore une place prépondérante dans la prise en charge des maladies mentales à Madagascar. Ainsi, nous nous sommes fixés comme objectif d'établir un état des lieux sur les soins de premier recours des malades mentaux. Nous avons mené une étude rétrospective descriptive s'étalant sur une période de 16 mois allant de janvier 2014 en avril 2015 au sein du service de psychiatrie du CHU de Befelatanana à Antananarivo. La prévalence des psychoses était de 25%. Le genre féminin (53%), l'ethnie merina (77%), les étudiants (45%), le niveau d'étude secondaire (40%), les célibataires (72%), la religion protestante (45%), ainsi que le niveau socio-économique moyen (57,5%) étaient prédominants. Dans les paramètres cliniques, le mode de début brutal (52%), le premier recours à la religion (40%), la présence d'antécédents des cas similaire (90%), étaient majoritaires. La schizophrénie était la pathologie la plus rencontrée dans la moitié des cas. Le délai d'amélioration en cas de traitement religieux et traditionnels était dans la moitié des cas de plus de 10 jours d'hospitalisation. Les patients ayant reçu une prise en charge psychiatrique en premier recours, étaient améliorés dans 75 % cas en moins de 10jours. Le retard du recours aux soins psychiatriques est une réalité à Madagascar qui aggrave le pronostic des psychoses. PMID:29632623

    Guidelines regarding antiretroviral therapy (ART) initiation in HIV infection have varied over time, with the 2015 World Health Organization recommendation suggesting ART initiation at the time of diagnosis regardless of CD4 T-cell counts. Herein, we investigated the influence of socio-demographic and clinical factors in addition to time trends on early ART initiation among participants of the Montreal Primary HIV Infection Study. The Montreal Primary HIV Infection Study is a prospective cohort established in three community medical centres (CMCs) and two university medical centres (UMCs). Recently diagnosed HIV-infected adults were categorized as receiving early (vs. delayed) ART if ART was initiated within 180 days of the baseline visit. Associations between early ART initiation and socio-demographic, socio-economic and behavioural information were examined. Independent associations of factors linked with early ART initiation were determined using multivariable binary logistic regression analysis. A total of 348 participants had a documented date of HIV acquisition of age of participants was 35 (28; 42) years and the majority were male (96%), having paid employment (63%), men who have sex with men (MSM) (78%) and one to four sexual partners in the last three months (70%). Participants presented with a median IQR HIV plasma viral load of 4.6 (3.7; 5.3) log 10 copies/ml, CD4 count of 510 (387; 660) cells/μl and were recruited in CMCs (52%) or UMCs (48%). Early ART initiation was observed in 47% of the participants and the trend followed a V-shaped curve with peaks in 1996 to 1997 (89%) and 2013 to 2015 (88%) with a dip in 2007 to 2009 (22%). Multivariable analyses showed that having a paid employment adjusted odds ratio (aOR: 2.43; 95% CI: 1.19, 4.95), lower CD4 count (aOR per 50 cell increase: 0.93; 95% CI: 0.87, 0.99) and care at UMCs (aOR: 2.03; 95% CI: 1.06 to 3.90) were independently associated with early ART initiation.

  12. Revitalización urbana y calidad de vida en el sector central de las ciudades de Montreal y México

    Carlos Alberto Tello Campos

    2017-07-01

    Full Text Available El abandono y consiguiente despoblamiento del sector central asociado a una desenfrenada expansión y poblamiento de los sectores periféricos de muchas de las grandes ciudades norteamericanas como Montreal y México, es un problema de actualidad muy difícil de resolver. Encontrar las causas que provocan dicho proceso se convierte en una necesidad crítica para mejorar el diseño de políticas urbanas que promuevan la re-utilización del espacio central, desalentando la utilización de los periféricos. En función de diversos programas urbanos tanto Canadienses como Mexicanos implementados al momento en el sector central de las dos ciudades mencionadas, ésta tesis se apoya en dos estudios de campo y los correspondientes análisis estadísticos de correlación y de regresión entre otros, para explicar el estado que el continuo revitalización urbana-calidad de vida-calidad del lugar guarda en el sector central de los casos de estudio desde la propia perspectiva de sus residentes. Los resultados informan que en revitalización urbana, los residentes Canadienses favorecen más a los atributos de calidad del lugar mientras que sus homólogos Mexicanos favorecen más a los de calidad de vida. ABSTRACT:  The neglect and further depopulation in many of the large North American cities’ inner-cores such as Montreal and Mexico coupled with sprawl and repopulation in their peripheral areas is very much a today’s problem difficult to solve. Finding out the causes that incite that process becomes a critical need to improve the design of urban policies that promote the re-utilization of the central space, to discourage the equivalent in the peripherals one. Taking into account several urban Canadian and Mexican programs already implemented on those cities’ inner cores, this thesis makes use of two field surveys and the corresponding correlation and regression statistical analyses among others, to explain the current urban revitalization > quality

  14. The phase-in and phase-out of European emissions of HCFC-141b and HCFC-142b under the Montreal Protocol: Evidence from observations at Mace Head, Ireland and Jungfraujoch, Switzerland from 1994 to 2004

    Derwent, R. G.; Simmonds, P. G.; Greally, B. R.; O'doherty, S.; McCulloch, A.; Manning, A.; Reimann, S.; Folini, D.; Vollmer, M. K.

    The mixing ratios of HCFC-141b (1,1-dichlorofluoroethane) and HCFC-142b (1-chloro-1,1-difluoroethane) have been rising steadily in baseline air at Mace Head, Ireland over the 10-year period from 1994 to 2004. These HCFCs are widely used replacements for the chlorofluorocarbons phased out under the Montreal Protocol and its subsequent amendments. Analysis of the HCFC content of regionally-polluted air arriving at Mace Head from the European continent shows that European emissions reached a peak during 2000-2001 and have declined subsequently, following the phase-out in their usage. European emissions of HCFC-141b have been further constrained by observations at the High-Alpine Jungfraujoch site. The reductions are consistent with the phase-out of HCFC production and use from the year 2001 onwards mandated by European regulations designed to exceed the requirements of the Montreal Protocol.

    2009-03-01

    Full Text Available Le présent article décrit un modèle visant à faciliter la compréhension du processus de transfert du contenu depuis sa source jusqu’à son utilisation. Un groupe de travail de Ressources naturelles Canada a étudié la nature du transfert des savoirs à l’aide d’un modèle de services, afin de découvrir et comprendre les modèles et processus sous-jacents. Les services de savoir sont des programmes qui créent et fournissent des produits organisationnels basés sur un contenu et ayant une valeur intégrée. Ces programmes sont destinés à être utilisés en interne ou transférés pour répondre aux souhaits et besoins d’un utilisateur externe. Les critères de conception du modèle sont les suivants : indépendance par rapport au contenu, concentration sur l’organisation, évolutivité, deux pilotes et deux niveaux de résolution. Le modèle est basé sur une chaîne de valeur dans laquelle la valeur est intégrée, déplacée ou extraite. Un système de services de savoir se divise en neuf étapes : générer, transformer, gérer, utiliser en interne, transférer, ajouter de la valeur, utiliser professionnellement, utiliser personnellement et évaluer. Les services de savoir sont fournis par l’intermédiaire d’un spectre de distribution allant de complexe à accessible. À chaque région du spectre de distribution correspond une série d’attributs qui influencent la manière dont les services sont fournis.This paper describes a model intended to increase understanding of how content is transferred from its source to its use. A Natural Resources Canada task group explored the nature of knowledge transfer with a services paradigm to discover and understand underlying patterns and processes. Knowledge Services are programs that produce and pro-vide content-based organizational outputs with embedded value that are intended to be used internally or transferred to meet external user wants or needs.

  17. Effets perturbateurs endocriniens des pesticides organochlores.

    Charlier, C; Plomteux, G

    2002-01-01

    Xenoestrogens such organochlorine pesticides are known to induce changes in reproductive development, function or behaviour in wildlife. Because these compounds are able to modify the estrogens metabolism, or to compete with estradiol for binding to the estrogen receptor, it may be possible that these products affect the risk of developing impaired fertility, precocious puberty or some kinds of cancer in man. Le plus ancien récit de lutte contre la pollution remonte à une légende indienne racontant que la divinité Sing-bonga était incommodée par les émanations des fours dans lesquels les Asuras fondaient leurs métaux (1). Evidemment depuis, la problématique n-a cessé de s-accroître et la contamination de la Terre par de nombreux polluants est devenue aujourd-hui un problème majeur de notre Société. La protection de notre environnement est une question capitale qui doit être respectée malgré la pression économique actuelle et qui ne cessera de croître au cours des prochaines années même si l-identification objective et indiscutable de ce qui est essentiel - donc devant être prioritairement garanti sur la planète - est difficile à cerner (2). « Un oiseau en mauvais état ne pond pas de bons oeufs » disait un proverbe grec. Mais ce n-est qu-à partir de la seconde moitié du XXème siècle que les toxicologues ont commencé à identifier les effets qu-avaient entraînés à l-échelle mondiale les pollutions émises aux XIXème siècle sur la faune sauvage et sur le cheptel (3). L-histoire contemporaine des pesticides industriels commence vers 1874 (synthèse des organochlorés) et se poursuit tout au long de ces 2 siècles en passant par la synthèse des organophosphorés (1950), des carbamates (1970) et des pyréthroïdes (1975) (4).

    1998-01-01

    Après la naissance, la croissance et les propriétés contractiles et métaboliques des fibres musculaires sont soumises à une régulation endocrinienne complexe. A l’exception des glucocorticoïdes, la plupart des hormones présente une action anabolique sur le tissu musculaire. Leur influence sur les caractéristiques des fibres est cependant très différente. Ainsi, les hormones somatotropes affectent peu la composition en fibres des muscles. La GH, comme l’IGF-1, régulerait cependant l’expression...

  19. The role of advocacy coalitions in a project implementation process: the example of the planning phase of the At Home/Chez Soi project dealing with homelessness in Montreal.

    Fleury, Marie-Josée; Grenier, Guy; Vallée, Catherine; Hurtubise, Roch; Lévesque, Paul-André

    2014-08-01

    This study analyzed the planning process (summer 2008 to fall 2009) of a Montreal project that offers housing and community follow-up to homeless people with mental disorders, with or without substance abuse disorders. With the help of the Advocacy Coalition Framework (ACF), advocacy groups that were able to navigate a complex intervention implementation process were identified. In all, 25 people involved in the Montreal At Home/Chez Soi project were surveyed through interviews (n=18) and a discussion group (n=7). Participant observations and documentation (minutes and correspondence) were also used for the analysis. The start-up phase of the At Home/Chez may be broken down into three separate periods qualified respectively as "honeymoon;" "clash of cultures;" and "acceptance & commitment". In each of the planning phases of the At Home/Chez Soi project in Montreal, at least two advocacy coalitions were in confrontation about their specific belief systems concerning solutions to address the recurring homelessness social problem, while a third, more moderate one contributed in rallying most key actors under specified secondary aspects. The study confirms the importance of policy brokers in achieving compromises acceptable to all advocacy coalitions. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Physical exercise improves cognitive function in people with mild cognitive impairment (MCI). However, information about whether the degree of MCI before exercise training affects improvement in cognitive function is lacking. Therefore, we aimed to investigate the cut-off value in a MCI screening tool that predicts reversal to normal cognitive function after exercise training in older adults with MCI. Participants included 112 Japanese community-dwelling older adult outpatients (37 men, 75 women; mean age 76.3 years). We administered the Japanese version of the Montreal Cognitive Assessment (MoCA-J) before and after exercise training. MCI was defined as a MoCA-J score cognitive function. The MoCA-J cut-off score to predict cognitive function potentially reversible to normal was 23, with receiver operating characteristic analysis showing an area under the curve of 0.80, sensitivity of 79.4% and specificity of 69.2%. Multiple logistic regression analysis to predict non-MCI after exercise training showed that MoCA-J score ≥23 (OR 6.9, P cognitive function that is potentially reversible to normal among community-dwelling Japanese older adults with MCI.

    2016-01-01

    Feral pigeons (Columbia livia) can harbor a range of zoonotic pathogens. A transversal study was undertaken to estimate the prevalence of feral pigeons infected by various pathogens in public areas in Montreal, Quebec. Cloacal swabs from captured birds were cultured for Salmonella spp. and Campylobacter spp. and tested by real-time polymerase chain reaction (RT-PCR) for the detection of Coxiella burnetii. An oropharyngeal swab was also submitted to real-time reverse-transcription polymerase chain reaction (RRT-PCR) for the detection of Newcastle disease virus. Among the 187 pigeons tested from 10 public areas, 9.1% (95% CI: 3.0 to 15.2) were positive for Campylobacter spp. with all strains identified as Campylobacter jejuni. The Campylobacter status of birds was not associated with individual characteristics of birds, with the exception of body score. None of the pigeons tested positive for the other pathogens. Direct or indirect contacts with feral pigeons may constitute a potential risk for Campylobacter infection in humans. PMID:26733736

    There is a shift toward making health care patient centered, whereby patients are part of medical decision-making and take responsibility for managing their health. Patient-reported outcomes (PROs) capture the patient voice and can be used to engage patients in medical decision-making. The objective of this paper is to present important factors from patients', clinicians', researchers', and decision-makers' perspectives that influence successful adoption of PROs in clinical practice. Factors recommended in this paper were informed by a patient partner. Based on themes arising from the Montreal Accord proceedings, we describe factors that influence the adoption of PROs and how PROs can have a positive effect by enhancing communication and providing opportunities to engage patients, carers, and clinicians in care. Consideration of patient factors (e.g., health literacy), family support and networks (e.g., peer-support networks), technology (e.g., e-health), and health care system factors (e.g., resources to implement PROs) is necessary to ensure PROs are successfully adopted. PRO evaluation plans most likely to succeed over the long term are those incorporating PROs identified by patients as necessary for self-management and that coincide with providers' needs for collaboratively developing treatment plans with patients and families.

    Existing evidence suggests that ambient ultrafine particles (UFPs) (regression model for UFPs in Montreal, Canada using mobile monitoring data collected from 414 road segments during the summer and winter months between 2011 and 2012. Two different approaches were examined for model development including standard multivariable linear regression and a machine learning approach (kernel-based regularized least squares (KRLS)) that learns the functional form of covariate impacts on ambient UFP concentrations from the data. The final models included parameters for population density, ambient temperature and wind speed, land use parameters (park space and open space), length of local roads and rail, and estimated annual average NOx emissions from traffic. The final multivariable linear regression model explained 62% of the spatial variation in ambient UFP concentrations whereas the KRLS model explained 79% of the variance. The KRLS model performed slightly better than the linear regression model when evaluated using an external dataset (R(2)=0.58 vs. 0.55) or a cross-validation procedure (R(2)=0.67 vs. 0.60). In general, our findings suggest that the KRLS approach may offer modest improvements in predictive performance compared to standard multivariable linear regression models used to estimate spatial variations in ambient UFPs. However, differences in predictive performance were not statistically significant when evaluated using the cross-validation procedure. Crown Copyright © 2015. Published by Elsevier Inc.

  5. Occupational exposure to diesel engine emissions and risk of lung cancer: evidence from two case-control studies in Montreal, Canada.

    Pintos, Javier; Parent, Marie-Elise; Richardson, Lesley; Siemiatycki, Jack

    2012-11-01

    To examine the risk of lung cancer among men associated with exposure to diesel engine emissions incurred in a wide range of occupations and industries. 2 population-based lung cancer case-control studies were conducted in Montreal. Study I (1979-1986) comprised 857 cases and 533 population controls; study II (1996-2001) comprised 736 cases and 894 population controls. A detailed job history was obtained, from which we inferred lifetime occupational exposure to 294 agents, including diesel engine emissions. ORs were estimated for each study and in the pooled data set, adjusting for socio-demographic factors, smoking history and selected occupational carcinogens. While it proved impossible to retrospectively estimate absolute exposure concentrations, there were estimates and analyses by relative measures of cumulative exposure. Increased risks of lung cancer were found in both studies. The pooled analysis showed an OR of lung cancer associated with substantial exposure to diesel exhaust of 1.80 (95% CI 1.3 to 2.6). The risk associated with substantial exposure was higher for squamous cell carcinomas (OR 2.09; 95% CI 1.3 to 3.2) than other histological types. Joint effects between diesel exhaust exposure and tobacco smoking are compatible with a multiplicative synergistic effect. Our findings provide further evidence supporting a causal link between diesel engine emissions and risk of lung cancer. The risk is stronger for the development of squamous cell carcinomas than for small cell tumours or adenocarcinomas.

    Despite the considerable prevalence of cognitive impairment in substance-using populations, there has been little investigation of the utility of cognitive screening measures within this context. In the present study the accuracy of three cognitive screening measures in this population was examined-the Mini-Mental State Examination (MMSE), the Addenbrooke's Cognitive Examination-Revised (ACE-R), and the Montreal Cognitive Assessment (MoCA). A sample of 30 treatment-seeking substance users and 20 healthy individuals living in the community were administered the screening measures and a neuropsychological battery (NPB). Agreement of classification of cognitive impairment by the screening measures and NPB was examined. Results indicated that the ACE-R and MoCA had good discriminative ability in detection of cognitive impairment, with areas under the receiver-operating characteristic (ROC) curve of .85 (95% confidence interval, CI [.75. .94] and .84 (95% CI [.71, .93]) respectively. The MMSE had fair discriminative ability (.78, 95% CI [.65, .93]). The optimal cut-score for the ACE-R was 93 (impairment = score of 92 or less), at which it correctly classified 89% of individuals as cognitively impaired or intact, while the optimal cut-score for the MoCA was cognitive impairment in the context of substance use.

  7. Multilateral trade measures in a post-2012 climate change regime? What can be taken from the Montreal Protocol and the WTO?

    Zhang Zhongxiang

    2009-01-01

    The climate-trade nexus gains increasing attention as governments are taking great efforts to forge a post-2012 climate change regime to succeed the Kyoto Protocol. This raises the issues of the scope of trade-related measures and of when and how they could be used. This paper discusses how far trade-related measures should be incorporated in that context. Drawing on an analogy to the Montreal Protocol and comparing developing country's climate mitigation and adaptation needs with the funding available, the paper argues that such measures should initially be applied only among Annex I or II countries. To discipline the use of unilateral trade measures at the international level, the paper emphasizes a need to define comparable climate efforts. Moreover, the Lieberman-Warner bill in the US Senate-taken as a proxy for future US climate legislation-is assessed, and found to be neither effective nor likely to be WTO-consistent. The paper is concluded by arguing that, in order to encourage developing countries to do more to combat climate change, developed countries should focus on carrots. Sticks can be incorporated, but only if they are credible and realistic and serve as a useful supplement to push developing countries to take actions or adopt policies and measures earlier than would otherwise have been the case.

    To provide a crosswalk between the recently proposed short Montreal Cognitive Assessment (s-MoCA) and Mini-Mental State Examination (MMSE) within a clinical cohort. A total of 791 participants, with and without neurologic conditions, received both the MMSE and the MoCA at the same visit. s-MoCA scores were calculated and equipercentile equating was used to create a crosswalk between the s-MoCA and MMSE. As expected, s-MoCA scores were highly correlated (Pearson r = 0.82, P < .001) with MMSE scores. s-MoCA scores correctly classified 85% of healthy older adults and 91% of individuals with neurologic conditions that impair cognition. In addition, we provide an easy to use table that enables the conversion of s-MoCA score to MMSE score. The s-MoCA is quick to administer, provides high sensitivity and specificity for cognitive impairment, and now can be compared directly with the MMSE. Copyright © 2017 the Alzheimer's Association.

    Cognitive impairment is one of the earliest, most common, and most disabling non-motor symptoms in Parkinson’s disease (PD). Thus, routine screening of global cognitive abilities is important for the optimal management of PD patients. Few global cognitive screening instruments have been developed for or validated in PD patients. The Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), and Dementia Rating Scale-2 (DRS-2) have been used extensively for cognitive screening in both clinical and research settings. Determining how to convert the scores between instruments would facilitate the longitudinal assessment of cognition in clinical settings and the comparison and synthesis of cognitive data in multicenter and longitudinal cohort studies. The primary aim of this study was to apply a simple and reliable algorithm for the conversion of MoCA to MMSE scores in PD patients. A secondary aim was to apply this algorithm for the conversion of DRS-2 to both MMSE and MoCA scores. The cognitive performance of a convenience sample of 360 patients with idiopathic PD was assessed by at least two of these cognitive screening instruments. We then developed conversion scores between the MMSE, MoCA, and DRS-2 using equipercentile equating and log-linear smoothing. The conversion score tables reported here enable direct and easy comparison of three routinely used cognitive screening assessments in PD patients. PMID:25381961

    Two conversion tables between the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) have recently been established for Parkinson's disease (PD). This study aimed to validate them in Korean patients with PD and to evaluate whether they could be influenced by educational level. A total of 391 patients with PD who undertook both the Korean MMSE and the Korean MoCA during the same session were retrospectively assessed. The mean, median, and root mean squared error (RMSE) of the difference between the true and converted MMSE scores and the intraclass correlation coefficient (ICC) were calculated according to educational level (6 or fewer years, 7-12 years, or 13 or more years). Both conversions had a median value of 0, with a small mean and RMSE of differences, and a high correlation between the true and converted MMSE scores. In the classification according to educational level, all groups had roughly similar values of the median, mean, RMSE, and ICC both within and between the conversions. Our findings suggest that both MMSE-MoCA conversion tables are useful instruments for transforming MoCA scores into converted MMSE scores in Korean patients with PD, regardless of educational level. These will greatly enhance the utility of the existing cognitive data from the Korean PD population in clinical and research settings.

    The patients with obstructive sleep apnea hypopnea syndrome (OSAHS) tend to develop cognitive deficits, which usually go unrecognized, and can affect their daily life. The Beijing version of the Montreal cognitive assessment (MoCA-BJ), a Chinese version of MoCA, has been used for the assessment of cognitive functions of OSAHS patients in clinical practice. So far, its reliability and validity have not been tested. This study examined the reliability and validity of MoCA-BJ in a cohort of adult OSAHS patients. 152 OSAHS patients, ranging from mild, moderate to severe, 49 primary snoring subjects and 40 normal controls were evaluated for cognitive functions by employing both MoCA-BJ and the Mini Mental State Examination (MMSE). Forty of them were re-tested by MoCA-BJ 14 days after the first test. Internal consistency, test-retest reliability, discriminate and concurrent validity of MoCA-BJ were analyzed. Internal consistency reliability by Cronbach's alpha was adequate (0.73). Intra-class correlation coefficient (ICC), an measure of test-retest reliability, was 0.87 (Preliable and stable. The MoCA-BJ was capable of detecting cognitive dysfunction by visuospatial and total MoCA-BJ score.

However, some of this research has also highlighted the fact that there are marked physical, socioeconomic, and cultural disparities in this population. Material and methods. To this end, this article presents the results of a survey conducted in 2015 in Montreal with 464 respondents aged 50 and over regarding their interests and leisure practices. Results. This study highlights the importance that persons in this age group give to physical and outdoor recreation as well as free and outdoor activities. However, this study has also confirmed that there exist, regarding the problem of leisure, more or less significant differences among seniors and baby boomers which need to be taken into account by local actors. Conclusions. The results obtained and the correlated analyses clearly indicate that the senior population is not homogeneous with respect to their practices and their leisure needs. This analytical finding confirms that leisure and community services must be planned, programmed, and promoted taking into account these generational differences, as well as physical, socioeconomic, and cultural differences.

    Full Text Available Les huiles marines représentent des sources potentielles d’acides gras polyinsaturés (AGPI dont les implications au niveau de la nutrition et de la santé sont avérées. Ces molécules sont extraites à partir de poissons, algues ou co-produits de la filière halieutique par des procédés de cuisson-pression, en présence de solvants ou par des techniques enzymatiques beaucoup moins drastiques. Des fractions plus ou moins purifiées en AGPI sont obtenues par cristallisation à froid, en présence de solvants organiques, complexation avec de l’urée, distillation moléculaire ou extraction par fluide supercritique. L’utilisation de lipases stéréospécifiques dans des procédés d’hydrolyse et d’estérification conduit à une diversité de molécules d’acylglycérols riches en AGPI trouvant de nombreuses applications dans le domaine de l’agroalimentaire et de la santé.

Stabiliser la formule des traces tordue est la méthode la plus puissante connue actuellement pour comprendre l'action naturelle du groupe des points adéliques d'un groupe réductif, tordue par un automorphisme, sur les formes automorphes de carré intégrable de ce groupe. Cette compréhension se fait en réduisant le problème, suivant les idées de Langlands, à des groupes plus petits munis d'un certain nombre de données auxiliaires; c'est ce que l'on appelle les données endoscopiques.

  5. Statutes of limitations: the special problem of DES suits

    Feigin, C.A.

    1981-01-01

    In 1971, medical studies determined that DES causes a rare type of vaginal cancer in a small number of daughters of mothers who took DES during pregnancy. Subsequently, medical studies determined that exposure to DES can cause other vaginal abnormalities in the daughters, some of which may be precancerous. As a result of these discoveries, many lawsuits have been filed by these daughters against DES manufacturers. Many DES suits may be barred by statutes of limitations, both because the number of years between the daughters' exposure to DES in utero and the discovery that DES can cause injuries exceeds the statutory period, and because the cancer or other injuries caused by DES may not develop for many additional years. This Note discusses two methods that DES plaintiffs may be able to use to overcome the potential statutes of limitations bar: the discovery rule, and state provisions which toll the statute of limitations for minors. The Note contends that courts should apply an expanded discovery rule to DES suits to avoid the unfair result of barring a claim before the plaintiff could have known that she had a cause of action. In addition, the Note argues that the injury which causes the statute of limitations to begin to run in DES suits should not be rigidly defined. Finally, the Note urges that courts allow eligible DES plaintiffs to take advantage of applicable state provisions that toll the statute of limitations for minors

  9. Das Konzept des 'Medialen Habitus'

    Sven Kommer

    2013-12-01

    Full Text Available Sven Kommer fragt in seinem Beitrag, inwieweit das Habitus-Konzept als Erklärungsmuster für die beobachtbare Zementierung sozialer Ungleichheit im Schulsystem greift. Dabei konstatiert der Beitrag, dass alle an der Weiterschreibung des Habitus-Konzepts beteiligten AutorInnen sich darin einig sind, dass es wichtige Beiträge für die Selbst-Aufklärung einer weitestgehend mediatisierten Gesellschaft leistet. Der Artikel geht dabei – auch angesichts der PISA-Studien – von dem empirischen Befund aus, dass die individuelle Ausprägung der Medienkompetenz aufs engste mit den Ressourcen des Elternhauses verbunden ist und sich dabei die elterlichen Formen der Medienerziehung unübersehbar mit den aktuellen medialen Handlungspraxen verbinden. Dieser Befund deckt sich auf weite Strecken auch mit den Ergebnissen der Bildungssoziologie Pierre Bourdieus, weshalb die Diskussionen zum medialen Habitus im Rahmen dieser Ausführungen auch mit empirischen Argumenten unterfüttert werden. Ganz in diesem Sinne arbeitet der Artikel auch heraus, dass die aus dem Kontext der Cultural Studies stammenden Thesen zur Nivellierung kultureller Milieu-Unterschiede wenig empirisch fundiert sind. Der Artikel betont dahingehend, dass hier eine unreflektierte Infiltration durch genuin neoliberales Gedankengut vorliegt, da mit ihr auch die Annahme einer "freien Wahl" von Lebensweg, Milieuzugehörigkeit oder Gender verbunden werden kann. Dabei wir auch eingehend der "Clash of Habitus" diskutiert, der zwischen Lehrenden und Lernenden stattfindet und das Augenmerk ein Mal mehr auf die Tatsache lenkt, das unser Bildungssystem auf dieser pädagogisch relevanten Ebene durch soziale Ungleichheiten gekennzeichnet ist. In his essay, Sven Kommer questions whether the notion of habitus is suitable to support the understanding of the obvious consolidation of inequality in the school system. He shows that all authors active in the continued use of the notion of habitus agree that it

  12. Some aspects of the validity of the Montreal Cognitive Assessment (MoCAfor evaluating cognitive impairment in Brazilian patients with Parkinson's disease

    Vitor Tumas

    Full Text Available ABSTRACT Background: The Montreal Cognitive Assessment (MoCA is a short global cognitive scale, and some studies suggest it is useful for evaluating cognition in patients with Parkinson's disease (PD. However, its accuracy has been questioned in studies involving patients with low education. Objective: We sought to assess whether some of the MoCA subtests contribute to the low accuracy of the test. Methods: We performed a cross-sectional retrospective analysis of clinical data in a cohort of 71 patients with PD, most with less than 8 years of education. Patients were examined using the MDS-UPDRS, Hoehn and Yahr and the MoCA. The data were analyzed using mainly descriptive statistics. Results: We analyzed the data of 66 patients that were not demented according to the clinical evaluation and classified them using the proposed cut-off MoCA scores for diagnosis of MCI and dementia. Thirteen patients (19.7% were classified as having normal cognition, 24 (36.3% MCI and 29 (43.9% dementia. Patients with dementia had longer disease duration (p=0.016 and lower education (p=0.0001. Total MoCA scores had a an almost normal distribution with a wide range of scores and only one maximum score. Performance on the MoCA was highly correlated with education (correlation coefficient=0.66, p=0.0001. At least five of the 10 MoCA subtests showed significant floor effects. Conclusion: We believe that some of the MoCA subtests may be too difficult to be completed by PD patients with low educational level, thus contributing to the test's poor diagnostic accuracy.

  13. Exposure to welding fumes increases lung cancer risk among light smokers but not among heavy smokers: evidence from two case–control studies in Montreal

    Vallières, Eric; Pintos, Javier; Lavoué, Jérôme; Parent, Marie-Élise; Rachet, Bernard; Siemiatycki, Jack

    2012-01-01

    We investigated relationships between occupational exposure to gas and arc welding fumes and the risk of lung cancer among workers exposed to these agents throughout the spectrum of industries. Two population-based case–control studies were conducted in Montreal. Study I (1979–1986) included 857 cases and 1066 controls, and Study II (1996–2001) comprised 736 cases and 894 controls. Detailed job histories were obtained by interview and evaluated by an expert team of chemist–hygienists to estimate degree of exposure to approximately 300 substances for each job. Gas and arc welding fumes were among the agents evaluated. We estimated odds ratios (ORs) and 95% confidence intervals (CIs) of lung cancer using logistic regression, adjusting for smoking history and other covariates. The two studies provided similar results, so a pooled analysis was conducted. Among all subjects, no significant association was found between lung cancer and gas welding fumes (OR = 1.1; 95% CI = 0.9–1.4) or arc welding fumes (OR = 1.0; 95% CI = 0.8–1.2). However, when restricting attention to light smokers, there was an increased risk of lung cancer in relation to gas welding fumes (OR = 2.9; 95% CI = 1.7–4.8) and arc welding fumes (OR = 2.3; 95% CI = 1.3–3.8), with even higher OR estimates among workers with the highest cumulative exposures. In conclusion, there was no detectable excess risk of lung cancer due to welding fumes among moderate to heavy smokers; but among light smokers we found an excess risk related to both types of welding fumes.

Two population-based case-control studies were conducted in Montreal. Study I (1979-1986) included 857 cases and 1066 controls, and Study II (1996-2001) comprised 736 cases and 894 controls. Detailed job histories were obtained by interview and evaluated by an expert team of chemist-hygienists to estimate degree of exposure to approximately 300 substances for each job. Gas and arc welding fumes were among the agents evaluated. We estimated odds ratios (ORs) and 95% confidence intervals (CIs) of lung cancer using logistic regression, adjusting for smoking history and other covariates. The two studies provided similar results, so a pooled analysis was conducted. Among all subjects, no significant association was found between lung cancer and gas welding fumes (OR = 1.1; 95% CI = 0.9-1.4) or arc welding fumes (OR = 1.0; 95% CI = 0.8-1.2). However, when restricting attention to light smokers, there was an increased risk of lung cancer in relation to gas welding fumes (OR = 2.9; 95% CI = 1.7-4.8) and arc welding fumes (OR = 2.3; 95% CI = 1.3-3.8), with even higher OR estimates among workers with the highest cumulative exposures. In conclusion, there was no detectable excess risk of lung cancer due to welding fumes among moderate to heavy smokers; but among light smokers we found an excess risk related to both types of welding fumes.

    To assess the usefulness of the Montreal Cognitive Assessment (MoCA) total score (MoCA-TS) and Memory Index Score (MoCA-MIS) in predicting conversion to Alzheimer's disease (AD) in individuals with mild cognitive impairment (MCI). Retrospective chart review. Community-based memory clinic. Individuals meeting Petersen's MCI criteria (N = 165). Baseline MoCA scores at MCI diagnosis were collected from charts of eligible individuals with MCI, and MoCA-TS, MoCA-MIS, and a cognitive domain index score were calculated to assess their prognostic value in predicting conversion to AD. One hundred fourteen participants progressed to AD (MCI-AD), and 51 did not (nonconverters; MCI-NC); 90.5% of participants with MCI with a MoCA-TS less than 20/30 and a MoCA-MIS less than 7/15 at baseline converted to AD within the average follow-up period of 18 months, compared with 52.7% of participants with MCI above the cutoffs on both scores. Individuals with multiple-domain amnestic MCI had the highest AD conversion rates (73.9%). Identifying individuals with MCI at high risk of conversion to AD is important clinically and for selecting appropriate subjects for therapeutic trials. Individuals with MCI with a low MoCA-TS and a low newly devised memory index score (MoCA-MIS) are at greater risk of short-term conversion to AD. © 2014, Copyright the Authors Journal compilation © 2014, The American Geriatrics Society.

    Understanding health care utilization by neighbourhood is essential for optimal allocation of resources, but links between neighbourhood immigration and health have rarely been explored. Our objective was to understand how immigrant composition of neighbourhoods relates to health outcomes and health care utilization of individuals living with diabetes. This is a secondary analysis of administrative data using a retrospective cohort of 111,556 patients living with diabetes without previous cardiovascular diseases (CVD) and living in the metropolitan region of Montreal (Canada). A score for immigration was calculated at the neighbourhood level using a principal component analysis with six neighbourhood-level variables (% of people with maternal language other than French or English, % of people who do not speak French or English, % of immigrants with different times since immigration (immigration scores, those living in neighbourhoods with high immigration scores were less likely to die, to suffer a CVD event, to frequently visit general practitioners, but more likely to visit emergency departments or a specialist and to use an antidiabetic drug. These differences remained after controlling for patient-level variables such as age, sex, and comorbidities, as well as for neighbourhood attributes like material and social deprivation or living in the urban core. In this study, patients with diabetes living in neighbourhoods with high immigration scores had different health outcomes and health care utilizations compared to those living in neighbourhoods with low immigration scores. Although we cannot disentangle the individual versus the area-based effect of immigration, these results may have an important impact for health care planning.

  17. Sensitivity of the Mini-Mental State Examination, Montreal Cognitive Assessment and the Addenbrooke's Cognitive Examination III to everyday activity impairments in dementia: an exploratory study.

    Giebel, Clarissa M; Challis, David

    2017-10-01

    The Mini-Mental State Examination (MMSE) is one of the most frequently used cognitive measures for dementia severity and linked to deficits in everyday functioning. Recently, the Montreal Cognitive Assessment (MoCA) and the Addenbrooke's Cognitive Examination III (ACE-III) increasingly substitute for the MMSE. However, there are no specific cutoffs in the ACE-III for mild dementia. The objectives of this exploratory study were to assess the sensitivity of each scale to everyday functioning and to examine the cutoffs between mild and moderate dementia on the ACE-III. People with mild dementia completed the MMSE, MoCA and ACE-III, whilst informal carers completed the Revised Interview for Deteriorations in Daily Living Activities for Dementia to rate their relative's initiative and performance of instrumental activities of daily living and the Katz activities of daily living scale. Data were analysed using correlation analysis, raw score comparisons, Cohen's kappa and receiver operating characteristics analysis. Thirty-three dyads completed the measures. The ACE-III was the most sensitive tool for everyday functioning performance, whilst its language subscale was specifically related to initiation of activities. The most suitable cutoff on the ACE-III between mild and moderate dementia was 61. Findings suggest the ACE-III more efficiently identifies everyday functional impairments. Further research is required to confirm these exploratory analyses of the cutoff between mild and moderate dementia on the ACE-III. Both functional impairment and stage of dementia are needed in the diagnostic process and in the clinical assessment of people with dementia. Copyright © 2016 John Wiley & Sons, Ltd.

    2015-12-01

    To improve the prevention, treatment and risk prediction of cardiovascular diseases, genetic markers and gene-diet interactions are currently being investigated. The Montreal Heart Institute (MHI) Biobank is suitable for such studies because of its large sample size (currently, n = 17 000), the availability of biospecimens, and the collection of data on dietary intakes of saturated (SFAs) and n-3 and n-6 polyunsaturated (PUFAs) fatty acids estimated from a 14-item food frequency questionnaire (FFQ). We tested the validity of the FFQ by correlating dietary intakes of these fatty acids with their red blood cell (RBC) content in MHI Biobank participants. Seventy-five men and 75 women were selected from the Biobank. We successfully obtained RBC fatty acids for 142 subjects using gas chromatography coupled to mass spectrometry. Spearman correlation coefficients were used to test whether SFA scores and daily intakes (g day(-1)) of n-3 and n-6 PUFAs correlate with their RBC content. Based on covariate-adjusted analyses, intakes of n-3 PUFAs from vegetable sources were significantly correlated with RBC α-linolenic acid levels (ρ = 0.23, P = 0.007), whereas n-3 PUFA intakes from marine sources correlated significantly with RBC eicosapentaenoic acid (ρ = 0.29, P = 0.0008) and docosahexaenoic acid (ρ = 0.41, P = 9.2 × 10(-7)) levels. Intakes of n-6 PUFAs from vegetable sources correlated with RBC linoleic acid (ρ = 0.18, P = 0.04). SFA scores were not correlated with RBC total SFAs. The MHI Biobank 14-item FFQ can appropriately estimate daily intakes of n-3 PUFAs from vegetable and marine sources, as well as vegetable n-6 PUFAs, which enables the possibility of using these data in future studies. © 2014 The British Dietetic Association Ltd.

    Montreal Cognitive Assessment (MoCA) has been proposed as a screening tool in vascular cognitive impairment. Diffusion tensor imaging is sensitive to white matter microstructural damage. We investigated if diffusion tensor imaging-derived indices are more strongly associated with performances on MoCA or on the widely used mini mental state examination in patients with mild cognitive impairment and small vessel disease. Mild cognitive impairment patients with moderate/severe degrees of white matter hyperintensities on MRI were enrolled. Lacunar infarcts, cortical atrophy, medial temporal lobe atrophy and median values of mean diffusivity and fractional anisotropy of the cerebral white matter were studied and correlated with cognitive tests performances. Seventy-six patients (mean age 75.1±6.8 years, mean years of education 8.0±4.3) were assessed. In univariate analyses, a significant association of both MoCA and mini mental state examination scores with age, education, cortical atrophy, and medial temporal lobe atrophy was found, whereas mean diffusivity and fractional anisotropy were associated with MoCA. In partial correlation analyses, adjusting for all demographic and neuroimaging variables, both mean diffusivity and fractional anisotropy were associated only with MoCA (mean diffusivity: r= -0.275, P=0.023; fractional anisotropy: r=0.246, P=0.043). In patients with mild cognitive impairment and small vessel disease, diffusion tensor imaging-measured white matter microstructural damage is more related to MoCA than mini mental state examination performances. MoCA is suited for the cognitive screening of patients with small vessel disease. © 2014 American Heart Association, Inc.

    As the rapid growth of the elderly population and the increased prevalence of Alezheimer's Disease and related disorders, there is an increasing need for effective cognitive screening. The Mini Mental State Examination (MMSE) is the most frequently used screening test of cognitive impairment because of its convenience. The Montreal Cognitive Assessment-Indonesian Version (MoCA-INA) has been validated and recently been used as a cognitive screening tool. The aim of this study was to compare the MMSE and MoCA-INA scores and to determine the correlation between the MMSE and MoCA-INA scores in elderly. This was a cross-sectional study including 83 elderly subjects from November 2016 until June 2017. We performed MMSE and MoCA-INA for assessment of cognitive function and the time between each test was at least 30 minutes. The study included 83 subjects which were consisted of 46 (55.4%) males and 37 (44.6%) females. The mean age was 69.19 ± 4.23 ranging from 65 to 79 years old. The average MMSE scores was 24.96 ± 3.38 (range 14 to 30). The average MoCA-INA scores was 21.06 ± 4.56 (range 5 to 30). The Pearson correlation coefficient between the scores was 0.71 (p<0.005). There were no significant differences of both scores based on history of hypertension, diabetes mellitus and previous stroke, but there was a significant difference in MMSE scores based on level of education. The MoCA-INA score showed a good correlation with the MMSE score. Both tests showed comparable results but MoCA-INA showed lower average with wider range of scores.

    The Montreal Cognitive Assessment (MoCA) and Mini Mental State Examination (MMSE) are brief screening instruments for cognitive disorders. Although these instruments have frequently been used in the detection of dementia, there is currently little knowledge on the validity to detect Korsakoff's syndrome (KS) with both screening instruments. KS is a chronic neuropsychiatric disorder associated with profound declarative amnesia after thiamine deficiency. A representative sample of 30 patients with KS and 30 age-, education-, gender- and premorbid-IQ-matched controls was administered the MoCA and MMSE. The area under the receiver operating characteristic curve (AUC) was calculated in addition to the sensitivity, specificity, positive predictive value, and negative predictive value for various cut-off points on the MoCA and MMSE. Compared with the MMSE, the MoCA demonstrated consistently superior psychometric properties and discriminant validity--AUC: MoCA (1.00 SE .003) and MMSE (0.92 SE .033). When applying a cut-off value as suggested in the manuals of both instruments, the MMSE (< 24) misdiagnosed 46.7% of the patients, while the MoCA (< 26) diagnosed all patients correctly. As a screening instrument with the most optimal cut-offs, the MoCA (optimal cutoff point 22/23, 98.3% correctly diagnosed) was superior to the MMSE (optimal cutoff point 26/27, 83.3% correctly diagnosed). We conclude that both tests have adequate psychometric properties as a screening instrument for the detection of KS, but the MoCA is superior to the MMSE for this specific patient population.

    OBJECTIVES To examine Montreal Cognitive Assessment (MoCA) performance in patients with Parkinson’s disease (PD) with “normal” global cognition according to Mini-Mental State Examination (MMSE) score. DESIGN A cross-sectional comparison of the MoCA and the MMSE. SETTING Two movement disorders centers at the University of Pennsylvania and the Philadelphia Veterans Affairs Medical Center. PARTICIPANTS A convenience sample of 131 patients with idiopathic PD who were screened for cognitive and psychiatric complications. MEASUREMENTS Subjects were administered the MoCA and MMSE, and only subjects defined as having a normal age- and education-adjusted MMSE score were included in the analyses (N = 100). As previously recommended in patients without PD, a MoCA score less than 26 was used to indicate the presence of at least mild cognitive impairment (MCI). RESULTS Mean MMSE and MoCA scores ± standard deviation were 28.8 ± 1.1 and 24.9 ± 3.1, respectively. More than half (52.0%) of subjects with normal MMSE scores had cognitive impairment according to their MoCA score. Impairments were seen in numerous cognitive domains, including memory, visuospatial and executive abilities, attention, and language. Predictors of cognitive impairment on the MoCA using univariate analyses were male sex, older age, lower educational level, and greater disease severity; older age was the only predictor in a multivariate model. CONCLUSION Approximately half of patients with PD with a normal MMSE score have cognitive impairment based on the recommended MoCA cutoff score. These results suggest that MCI is common in PD and that the MoCA is a more sensitive instrument than the MMSE for its detection. PMID:19170786

    Background/Aims The goal of this study was to examine the reliability and validity of the Changsha version of the Montreal Cognitive Assessment (MoCA-CS) in ischemic cerebrovascular disease patients of Hunan Province, China, and to explore the optimal cutoff score for detecting vascular cognitive impairment-no dementia (VCI-ND) and vascular dementia (VD). Methods Three hundred and thirty-eight ischemic cerebrovascular disease patients (131 with normal cognition, 111 with VCI-ND, and 96 with VD) and 132 healthy controls were recruited. All participants accepted examination by the MoCA-CS, Mini-Mental State Examination (MMSE), and other related scales. A detailed neuropsychological battery was used for making a final cognitive diagnosis. SPSS 16.0 statistical software was used for reliability, validity examination, and optimal cutoff score detection. Results Cronbach's α of the MoCA-CS was 0.884, and test-retest and interrater reliability of the MoCA-CS were 0.966 and 0.926, respectively. MoCA-CS scores were highly correlated with MMSE scores (r = 0.867) and simplified intelligence quotients (r = 0.822). The results indicate that 1 point should be added for subjects with less than 6 years of education, and that the optimal cutoff score for detecting VCI-ND is 26/27 (sensitivity 96.1%, specificity 75.6%), whereas the optimal cutoff score for detecting VD is 16/17 (sensitivity 92.7%, specificity 96.3%). Conclusion The MoCA-CS has good reliability and validity, and is a useful cognitive screening instrument for detecting VCI in the Chinese population. PMID:23637698

    To examine the discriminant validity of the Montreal Cognitive Assessment (MoCA) and the Mini-Mental State Examination (MMSE) in detecting patients with cognitive impairment at higher risk for dementia at a memory clinic setting. Memory clinic patients were administered the MoCA, MMSE, and a comprehensive formal neuropsychological battery. Mild cognitive impairment (MCI) subtypes were dichotomized into two groups: single domain-MCI (sd-MCI) and multiple domain-MCI (md-MCI). Area under the receiver operating characteristic curve (ROC) analysis was used to compare the discriminatory ability of the MoCA and the MMSE. Two hundred thirty patients were recruited, of which 136 (59.1%) were diagnosed with dementia, 61 (26.5%) with MCI, and 33 (14.3%) with no cognitive impairment (NCI). The majority of MCI patients had md-MCI (n = 36, 59%). The MoCA had significantly larger AUCs than the MMSE in discriminating md-MCI from the lower risk group for incident dementia (NCI and sd-MCI) [MoCA 0.92 (95% CI, 0.86-0.98) vs. MMSE 0.84 (95% CI, 0.75-0.92), p = 0.02). At their optimal cut-off points, the MoCA (19/20) remained superior to the MMSE (23/24) in detecting md-MCI [sensitivity: 0.83 vs. 0.72; specificity: 0.86 vs. 0.83; PPV: 0.79 vs. 0.72; NPV: 0.89 vs. 0.83; correctly classified: 85.1% vs. 78.7%]. The MoCA is superior to the MMSE in the detection of patients with cognitive impairment at higher risk for incident dementia at a memory clinic setting.

    To assess the validity of the Montreal Cognitive Assessment (MoCA) and the Mini-Mental State Examination (MMSE) in the detection of vascular mild cognitive impairment (VaMCI) in patients with subcortical ischemic vascular disease (SIVD). Among 102 SIVD patients, both cutoff scores of the MMSE and MoCA for differentiating VaMCI from no cognitive impairment (NCI) or differentiating VaMCI from vascular dementia (VaD) were determined by the receiver operator characteristic (ROC) analysis. Optimal sensitivity with specificity of cutoff scores was obtained after the raw scores were adjusted for education. After adjusting for education, the MoCA cutoff score for differentiating VaMCI from NCI was at 24/25 and that for differentiating VaMCI from VaD was at 18/19. After applying the adjusted MoCA scores from 19 to 24 to identify VaMCI in all SIVD patients, sensitivity was at 76.7% and specificity was at 81.4% (κ = 0.579). The adjusted cutoff score of the MMSE for differentiating VaMCI from NCI was at 28/29 and that for differentiating VaMCI from VaD was at 25/26. The sensitivity and specificity of the adjusted MMSE was at 58.1 and 71.2%, respectively, when using the score from 26 to 28 to identify VaMCI in SIVD patients (κ = 0.294). The MoCA detected subcortical VaMCI better than the MMSE. © 2013 S. Karger AG, Basel.

    To determine if there is an association between hearing loss and poorer cognitive scores on Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) and to determine if poor hearing acuity affects scoring on the cognitive screening tests of MMSE and MoCA. One hundred fourteen elderly patients (Singapore residents) aged between 55 and 86 years were sampled. Participants completed a brief history questionnaire, pure tone audiometry, and 2 cognitive screening tests-the MMSE and MoCA. Average hearing thresholds of the better ear in the frequencies of 0.5, 1, 2, and 4 kHz were used for data analysis. Hearing loss was significantly associated with poorer cognitive scores in Poisson regression models adjusted for age. Mini-Mental State Examination scores were shown to decrease by 2.8% (P = .029), and MoCA scores by 3.5% (P = .013) for every 10 dB of hearing loss. Analysis of hearing-sensitive components of "Registration" and "Recall" in MMSE and MoCA using chi-square tests showed significantly poorer performance in the hearing loss group as compared to the normal hearing group. Phonetic analysis of target words with high error rates shows that the poor performance was likely contributed by decreased hearing acuity, on top of a possible true deficit in cognition in the hearing impaired. Hearing loss is associated with poorer cognitive scores on MMSE and MoCA, and cognitive scoring is likely confounded by poor hearing ability. This highlights an important, often overlooked aspect of sensory impairment during cognitive screening. Provisions should be made when testing for cognition in the hearing-impaired population to avoid over-referral and subsequent misdiagnoses of cognitive impairment.

    The Montreal Cognitive Assessment (MoCA) accurately differentiates mild cognitive impairment (MCI) from mild dementia and normal controls (NC). While the MoCA is validated in multiple clinical settings, few studies compare it with similar tests also designed to detect MCI. We sought to investigate how the shorter Quick Mild Cognitive Impairment (Qmci) screen compares with the MoCA. Consecutive referrals presenting with cognitive complaints to a teaching hospital geriatric clinic (Fremantle, Western Australia) underwent a comprehensive assessment and were classified as MCI (n = 72) or dementia (n = 109). NC (n = 41) were a sample of convenience. The Qmci and MoCA were scored by trained geriatricians, in random order, blind to the diagnosis. Median Qmci scores for NC, MCI and dementia were 69 (+/-19), 52.5 (+/-12) and 36 (+/-14), respectively, compared with 27 (+/-5), 22 (+/-4) and 15 (+/-7) for the MoCA. The Qmci more accurately identified cognitive impairment (MCI or dementia), area under the curve (AUC) 0.97, than the MoCA (AUC 0.92), p = 0.04. The Qmci was non-significantly more accurate in distinguishing MCI from controls (AUC 0.91 vs 0.84, respectively = 0.16). Both instruments had similar accuracy for differentiating MCI from dementia (AUC of 0.91 vs 0.88, p = 0.35). At the optimal cut-offs, calculated from receiver operating characteristic curves, the Qmci (≤57) had a sensitivity of 91% and specificity of 93% for cognitive impairment, compared with 87% sensitivity and 80% specificity for the MoCA (≤23). While both instruments are accurate in detecting MCI, the Qmci is shorter and arguably easier to complete, suggesting that it is a useful instrument in an Australian geriatric outpatient population.

    Cognitive impairment in end-stage renal disease patients is associated with an increased risk of mortality. We examined the cognitive function in hemodialysis (HD) patients and compared the Korean versions of the Montreal Cognitive Assessment (K-MoCA) and of the Mini-Mental State Examination (K-MMSE) to identify the better cognitive screening instrument in these patients. Thirty patients undergoing hemodialysis and 30 matched reference group of apparently healthy control were included. All subjects underwent the K-MoCA, K-MMSE and a neuropsychological test battery to measure attention, visuospatial function, language, memory and executive function. All cognitive data were converted to z-scores with appropriate age and education level prior to group comparisons. Cognitive performance 1.0 SD below the mean was defined as modest cognitve impairment while 1.5 below the mean was defined as severe cognitive impairment. Modest cognitive impairment in memory plus other cognitive domains was detected in 27 patients (90%) while severe cognitive impairment in memory plus other cognitive domains was detected in 23 (77%) patients. Total scores in the K-MoCA were significantly lower in HD patients than in the reference group. However, no significant group difference was found in the K-MMSE. The K-MMSE ROC AUC (95% confidence interval) was 0.72 (0.59-0.85) and K-MoCA ROC AUC was 0.77 (0.65-0.89). Cognitive impairment is common but under-diagnosed in this population. The K-MoCA seems to be more sensitive than the K-MMSE in HD patients.

    Assessment of cognitive status poststroke is recommended by guidelines but follow-up can often not be done in person. The Telephone Interview of Cognitive Status (TICS) and the Telephone Montreal Cognitive Assessment (T-MoCA) are considered useful screening instruments. Yet, evidence to define optimal cut-offs for mild cognitive impairment (MCI) after stroke is limited. We studied 105 patients enrolled in the prospective DEDEMAS study (Determinants of Dementia After Stroke; NCT01334749). Follow-up visits at 6, 12, 36, and 60 months included comprehensive neuropsychological testing and the Clinical Dementia Rating scale, both of which served as reference standards. The original TICS and T-MoCA were obtained in 2 separate telephone interviews each separated from the personal visits by 1 week (1 before and 1 after the visit) with the order of interviews (TICS versus T-MoCA) alternating between subjects. Area under the receiver-operating characteristic curves was determined. Ninety-six patients completed both the face-to-face visits and the 2 interviews. Area under the receiver-operating characteristic curves ranged between 0.76 and 0.83 for TICS and between 0.73 and 0.94 for T-MoCA depending on MCI definition. For multidomain MCI defined by multiple-tests definition derived from comprehensive neuropsychological testing optimal sensitivities and specificities were achieved at cut-offs <36 (TICS) and <18 (T-MoCA). Validity was lower using single-test definition, and cut-offs were higher compared with multiple-test definitions. Using Clinical Dementia Rating as the reference, optimal cut-offs for MCI were <36 (TICS) and approximately 19 (T-MoCA). Both the TICS and T-MoCA are valid screening tools poststroke, particularly for multidomain MCI using multiple-test definition. © 2017 American Heart Association, Inc.

    Crohn's disease (CD) exhibits significant clinical heterogeneity. Classification systems attempt to describe this; however, their utility and reliability depends on inter-observer agreement (IOA). We therefore sought to evaluate IOA using the Montreal Classification (MC). De-identified clinical records of 35 CD patients from 6 Australian IBD centres were presented to 13 expert practitioners from 8 Australia and New Zealand Inflammatory Bowel Disease Consortium (ANZIBDC) centres. Practitioners classified the cases using MC and forwarded data for central blinded analysis. IOA on smoking and medications was also tested. Kappa statistics, with pre-specified outcomes of κ>0.8 excellent; 0.61-0.8 good; 0.41-0.6 moderate and ≤0.4 poor, were used. 97% of study cases had colonoscopy reports, however, only 31% had undergone a complete set of diagnostic investigations (colonoscopy, histology, SB imaging). At diagnosis, IOA was excellent for age, κ=0.84; good for disease location, κ=0.73; only moderate for upper GI disease (κ=0.57) and disease behaviour, κ=0.54; and good for the presence of perianal disease, κ=0.6. At last follow-up, IOA was good for location, κ=0.68; only moderate for upper GI disease (κ=0.43) and disease behaviour, κ=0.46; but excellent for the presence/absence of perianal disease, κ=0.88. IOA for immunosuppressant use ever and presence of stricture were both good (κ=0.79 and 0.64 respectively). IOA using MC is generally good; however some areas are less consistent than others. Omissions and inaccuracies reduce the value of clinical data when comparing cohorts across different centres, and may impair the ability to translate genetic discoveries into clinical practice.

    Socio-demographics and workplace stress may affect men and women differently. The aim of this cross-sectional study was to assess sex-specific interactions among age, occupational status, and workplace Demand-Control-Support (D-C-S) factors in relation to psychiatric symptoms and allostatic load levels representing multi-systemic "wear and tear". It was hypothesized that beyond main effects, D-C-S factors would be moderated by occupational status and age in sex-specific directions predictive of subjective psychiatric symptoms and objective physiological dysregulations. Participants included healthy male (n = 81) and female (n = 118) Montreal workers aged 20 to 64 years (Men: M = 39.4 years, SD = 11.3; Women: M = 42.8 years, SD = 11.38). The Job Content Questionnaire was administered to assess workplace D-C-S factors that included psychological demands, decisional latitude, and social support. Occupational status was coded using the Nam--Powers--Boyd system derived from the Canadian census. Psychiatric symptoms were assessed using the Beck Anxiety Scale and the Beck Depression Inventory II. Sex-specific allostatic load indices were calculated based on fifteen biomarkers. Regression analyses revealed that higher social support was associated with less depressive symptoms in middle aged (p = 0.033) and older men (p = 0.027). Higher occupational status was associated with higher allostatic load levels for men (p = 0.035), while the reverse occurred for women (p = 0.048). Women with lower occupational status but with higher decision latitude had lower allostatic load levels, as did middle-aged (p = 0.031) and older women (p = 0.003) with higher psychological demands. In summary, age and occupational status moderated workplace stress in sex-specific ways that have occupational health implications.

  14. Des broussailles dans les prairies alpines

    Olivier Camacho

    2009-03-01

    Full Text Available Landscape closing due to the decline in agricultural activity is considered to be a major problem in the Alps. Abondance Valley provides a good example of this phenomenon and is also representative of a paradox commonly found in the Northern French Alps: the mountainsides and alpine pastures are still used, whereas they are becoming increasingly afforested. Environmental conditions play a major role in the localisation of agricultural land uses, but they are not sufficient to explain why pastures still in use are being invaded by shrub. Even if cutting makes it possible to effectively control the encroachment by woody species, this is not true for uncut pastures where grazing is not able to keep up with grass production. This situation is repeated every year and is the likely cause of the colonisation by woody species. To ensure their forage system and to simplify their work, farmers tend to establish grazing units that are oversized in relation to the needs of their animals. They implement compensatory practices that consist of mechanical maintenance as a complement to grazing to limit the dynamics of woody species. These labour-intensive practices are not used on all of the pastures. The analysis of farmers’ practices by agronomists is therefore a useful complement to studies of physical and socio-economic environments, at the level of the grazed field as well as at that of the valley as a whole.La dégradation des paysages par suite du recul de l’activité agricole est considérée comme un enjeu majeur dans les Alpes. La vallée d’Abondance illustre bien ce phénomène de fermeture de l’espace mais elle est en outre représentative d’un paradoxe assez répandu dans les Alpes du nord françaises : les versants et les alpages sont encore exploités et pourtant ils se boisent progressivement. Les conditions de milieux jouent un rôle majeur sur la localisation des usages agricoles de l'espace, mais elles ne peuvent pas suffire pour

    La notion de tiers-lieux se développe de manière essentiellement empirique. Elle recouvre des réalités multiples, comme des projets de coworking spaces, de living labs et de fab labs. Certains tiers-lieux s’intéressent tout particulièrement à la ville et aux nouvelles conditions de la fabrique urbaine. En s’appuyant sur des méthodes d’innovation ouverte et le potentiel des outils numériques, ces tiers-lieux défendent l’idée d’un urbanisme qui ne soit plus le patrimoine exclusif d’experts, mai...
