    Full Text Available Project delays in the construction industry are a universal or large-scale observable fact affecting not only the construction industry but the overall economy of countries as well. As far as the Malaysian construction industry is concerned, project delays are common problems in the construction industry, particularly in housing development. The objective of this study is to evaluate and identify the causes and the consequences of project delays in private housing development projects in Malaysia, and the remedies that can minimize these delays. The top ten causes of delays are weather conditions, poor site conditions, poor site management, incomplete documents, lack of experience, financial problems, contract modifications, delay in the approval of major variations, contractor coordination problems with other parties, and construction mistakes and defective works. It has been analysed that the causes of the delays point to the contractor factors, which contribute to the major factors that cause project delays in private housing development projects. The consequences of the delays include time overrun, cost overrun, differences in opinion, negotiations, legal actions and total abandonment. Herewith are presented some recommendations to minimize these project delays.

    Full Text Available Construction delays are a common phenomenon in civil engineering projects in Egypt including road construction projects. Therefore, it is essential to study and analyze causes of road construction delays. This paper studied a list of construction delay causes gathered from literature having different types of construction, different countries, different periods and different numbers of delay causes and delay groups. A questionnaire and personal interviews have formed the basis of this paper listing 293 delay causes. The questionnaire survey was distributed to 500 construction participants and 389 were received who represent consultants, contractors and site/design engineers excluding the owner representing the government in road projects as one party only. Relative Importance Index (RII is calculated and according to the highest values the top twenty and the least twenty delay causes of construction projects in Egypt are determined. A case study is analyzed and compared to the most important delay causes in the paper. The test results reveal good correlation of causes and groups between contractors and site/design engineers and between consultants and site design engineers and a somewhat low correlation between contractors and consultants. So there are no root causes that can be taking for granted to be most or least effective delay causes. Proposed model for predicting actual road construction project duration was developed; a real case study tested the accuracy of proposed model. According to the analysis of case study, the most contributing causes and groups to delays were discussed, and some future recommendations were proposed in order to control and minimize delays in road construction projects. These findings can be helpful for project managers to mitigate the road construction delays in Egypt. In order to effectively overcome the road construction delays in developing countries, suggestions are made for fundamental and large

    Full Text Available Construction industry in Malaysia is facing a serious issue of construction delay causing a significant amount of time over run and cost over run. Various studies have addressed the issue of construction delay, however, most of studies focused on identifying causes of delay. Less attention has been paid of assessing effects of construction delay. Hence this study is aimed to assess effects of construction delay on MARA large projects. Investigation approach for study includes the site study of 30 MARA  large projects selected from various areas of Malaysia and structured questionnaire survey among client, consultant and contractor personnel’s. It is important to note that 90% of MARA projects are experiencing time overrun. Data was analyzed with statistical analysis  to calculate rank of the effects of delays and correlation with spearman formula to identify the interrelationship between attributes of effects. Results showed that time over-run and cost over-run are most significant effects of delay on MARA construction projects. Time over-run has high degree of correlation with cost over-run and moderate degree of correlation with disputes.

    Perfect Space-Time Codes (STC) are optimal codes in their original construction for Multiple Input Multiple Output (MIMO) systems. Based on Cyclic Division Algebras (CDA), they are full-rate, full-diversity codes, have Non-Vanishing Determinants (NVD) and hence achieve Diversity-Multiplexing Tradeoff (DMT). In addition, these codes have led to optimal distributed space-time codes when applied in cooperative networks under the assumption of perfect synchronization between relays. However, they loose their diversity when delays are introduced and thus are not delay-tolerant. In this paper, using the cyclic division algebras of perfect codes, we construct new codes that maintain the same properties as perfect codes in the synchronous case. Moreover, these codes preserve their full-diversity in asynchronous transmission.

    Full Text Available The construction industry continues to be the driving force in the growth of the nation’s socio economic development. One of the major issues in large construction industry is its frequent delay where this delay decelerates the multiplier effects to the economy. This paper presents the study of a survey on significant cause of delay and its effects in large MARA (Majlis Amanah Rakyat construction project in the views of project management consultants (PMC. Respondents of this survey were personnel that work as PMC ranging from the executives, managerial and supporting groups. The result revealed that the five most significant delay causes as seen by PMC were cash flow and financial difficulties faced by contractors, contractor’s poor site management, inadequate contractor experience, shortage of site workers and ineffective planning and scheduling by contractors and its three most significant effects were time overrun, cost overrun and arbitration. Hopefully, the findings of this study will at least shade some lights to the problems faced by Malaysia construction industry particularly MARA large construction project and effort can be taken to improve it.

    Full Text Available The problem of project delays is a fact that occurs mostly in construction industry of Pakistan. Delays are always measured as expensive to all parties concerned in the projects and very often it will result in clash, claims, total desertion and much difficult for the feasibility and it slows the growth of construction sector. For analyzing the causes of delay, an appraisal on construction project’s time performance was conducted. The main objective of this study is the identification of factors of delay and their effects on the success and completion of project. The most common factor of delay are natural disaster in Pakistan like flood and earthquake and some others like financial and payment problems, improper planning, poor site management, insufficient experience, shortage of materials and equipment etc. This paper covers the delay factors and causes of delay and some suggestion for reducing these delays in large construction projects in Pakistan.

    Reservoir computing is a novel bio-inspired computing method, capable of solving complex tasks in a computationally efficient way. It has recently been successfully implemented using delayed feedback systems, allowing to reduce the hardware complexity of brain-inspired computers drastically. In this approach, the pre-processing procedure relies on the definition of a temporal mask which serves as a scaled time-mutiplexing of the input. Originally, random masks had been chosen, motivated by the random connectivity in reservoirs. This random generation can sometimes fail. Moreover, for hardware implementations random generation is not ideal due to its complexity and the requirement for trial and error. We outline a procedure to reliably construct an optimal mask pattern in terms of multipurpose performance, derived from the concept of maximum length sequences. Not only does this ensure the creation of the shortest possible mask that leads to maximum variability in the reservoir states for the given reservoir, it also allows for an interpretation of the statistical significance of the provided training samples for the task at hand.

    The Rey-Osterrieth (ROCF) and Taylor (TCF) complex figure tests are widely used to assess visuospatial and constructional abilities as well as visual/non-verbal memory. Normative data adjusted to the cultural and linguistic reality of older Quebec-French individuals is still nonexistent for these tests. In this article, we report the results of two studies that aimed to establish normative data for Quebec-French people (aged at least 50 years) for the copy, immediate recall, and delayed recall trials of the ROCF (Study 1) and the TCF (Study 2). For both studies, the impact of age, education, and sex on test performance was examined. Moreover, the impact of copy time on test performance, the impact of copy score on immediate and delayed recall score, and the impact of immediate recall score on delayed recall performance were examined. Based on regression models, equations to calculate Z scores for copy and recall scores are provided for both tests.

    Full Text Available Time performance of a project is usually a particularly important consideration for the construction parties. Often, the most troublesome construction disputes involve delay and failure to complete the work in the specified time frame. Many variables have an impact upon construction delay in Saudi Arabia. This study aims at identifying the risk matrix for delay causes in construction projects in Saudi Arabia from consultants’ viewpoint. A questionnaire survey was undertaken of 51 consultants working on construction projects in the Northern Province of Saudi Arabia. Thirty five delay causes were identified through literature review. The study concluded that the top delay causes in construction projects in Saudi Arabia from consultants’ perspective are: bid award for lowest price, changes in material types and specifications during construction, contract management, duration of contract period, fluctuation of prices of materials, frequent changes in design, improper planning, inflationary pressure, lack of adequate manpower, long period between design and time of implementation, payments delay, poor labor productivity and rework.

    Full Text Available The delay in construction project completion is a common phenomenon that occurs in the construction industry, especially where the government projects are concerned. This survey will center on the Ninth Malaysia Plan project delay as evidenced in the Universiti Kebangsaan Malaysia campus. It will generally examine delay-related issues, which include the definition, type and category of delay, as well as the contributing factors (theoretically or practically that lead to delay in the project implementation. Data was compiled from literature review, interview and survey. Data obtained from the survey was analysed using the ‘relative Important Index (RII’ whereby the source with the highest RII is one that mostly influences the delay. The critical source of delay is due to the fact that the project contractor does not have enough working capital, the late advance payment, the delay in the client or consultant endorsing the study, issues involving contractor management, the scarcity of construction materials and new instructions for additional construction work.

    The intent of this study is to determine the extent of delays experienced in planning and constructing transmission lines in the continental United States. The reasons for the delays are identified for each line studied and their effect on the total electrical system is sought. Data was collected for 136 different lines either recently built or currently under study. Statistics were developed for each line in several categories and comparisons of lines delayed were made by company, area served and generation capacity. From the study presented here it was found that: right-of-way acquisition procedures including condemnation and easement negotiation practices delay more projects than local, state and federal regulatory requirements combined; load growth reductions particularly in the east have reduced the impact of regulatory delays; the south, southeast and southwestern areas of the country experience fewer delays in constructing transmission lines than the more populated states, and the cost for corridor delays was responded to for only 17 of the 142 projects surveyed. By far the most costly delay is the expense of condemning land for transmission right-of-way.

    It is crucial for the nuclear power plant project decision makers and management personnel to identify the actual factors of construction delay and their ranking in order to take preventive actions. NPP project is complex in nature and the construction phase is one of the most key phase which is subject to many factors result from many sources. From experience, nuclear projects have faced challenges similar to other complex mega projects with additional nuclear specific issues and life time cost of nuclear reactor is concentrated upfront as capital cost, and therefore delays in construction may become intolerable in terms of both lost revenues and interest on the capital. Budget over-runs and delays on next generation new build nuclear projects in recent years clearly demonstrate that the nuclear industry continues to repeat its failed management and project control processes of the past. Similar to major infra-structure projects, actual completion times can vary substantially from initial estimates but this uncertainty is too crucial to the nuclear industry due to high levels of capital at risk, for every year a project is delayed the levelized cost of electricity increases by approximately 8-10%. causes of delay, to develop a generalized AHP model for delay factors, and to prioritize the risk in different factors in various levels of construction phase in international turnkey NPP project. This paper describes and prioritizes Nuclear Power Plant (NPP) construction schedule delay factor for turnkey international project. This study also determines the different party's importance in percentage behind the construction schedule delay of NPP which constitutes main contractor (28.4%), regulatory authority (27.3%), financial and country factor (23.5%), and utility (20.8%). Decision makers of nuclear industry can understand the significance of different factors on NPP construction phase and they can apply risk informed decision making to avoid unexpected

    Full Text Available Construction project delays emanates from multiplicity of different sources of risk events. This, combined with high uncertainty in cause-effect relationships between the events and their impacts on project completion dates, have created immense difficulties in apportioning project delay responsibilities amongst contracting parties. This challenge is now dealt with by various delay analysis approaches, yet delay claims settlement continues to be a troublesome undertaking. Empirical research on these approaches as to their application in practice is limited, although such studies provide important reference sources to practitioners and researchers. As a contribution to addressing this gap, this paper reports on practitioners’ views on the approaches based on a UK nation-wide questionnaire survey of construction and consulting companies. The key findings of the study include: (1 delay claims are often resolved late and not close in time of occurrence of the delay events, creating more difficulties; (2 simplistic delay analysis approaches are widely used in practice and form the basis of successful claim resolutions, although they have major weaknesses; (3 the sophisticated approaches, although are more robust, are generally not popular in practice. To promote the use of these reliable approaches and help reduce or avoid disputes amongst claims parties, programming and record keeping practices must be improved as they do not facilitate the use of the approaches.

    Full Text Available There is an increase in the number of construction projects experiencing extensive delays leading to exceeding initial time and cost budget.  This paper reviews 41 studies around the world which surveyed the delay factors and classified them into Groups.  The main purpose of this paper is to review literature, each of which have categorized the causes that are responsible for time delays and cost overrun in projects. The collected list has 113 causes for delays categorized in to 18 different groups.  Most of the researches have analysed the responses from the Questionnaire survey.    The collected data are used to rank the problem.  The data are further used to investigate and analyse Important Index, Frequency Index, Severity Index, Relative Important Index, Relative Importance Weight, Weighted Average, Mean, Standard Deviation and Variance.  The collective comparison has revealed that the ranking given by all the researchers is not the same.  Further each and every study has different rank ratings for the different group of the delays.  This review paper attempts to provide an updated compilation of the earlier studies on ranking of the delay causers, which are never similar and constant for universal projects.  It is concluded that a separate study is required for identifying the factors causing delay for projects operated in Sabah, East Malaysia.

  14. Optical Orthogonal Code Construction Using Rejected Delays Reuse for Increasing SubWavelength-Switching Capacity

    Khattab, Tamer M. S.; Alnuweiri, Hussein M.

    2006-09-01

    Using a mathematical proof, the authors establish that in element-by-element greedy algorithms based on extended set representation of optical orthogonal codes (OOCs), smaller delay elements rejected during a construction step can be accepted in later steps. They design a novel algorithm that exploits this property and call it the rejected delays reuse (RDR) greedy algorithm. They show that employing the RDR method leads to code lengths that are shorter than those achieved for OOCs constructed using the classical greedy algorithm for the same code weight and the same number of simultaneous codes constraints. They then define a quantitative measure (factor) for OOCs efficiency based on its ability to expand subwavelength-switching capacity. They call this factor the expansion efficiency factor. They use this factor to show that reducing the code length, for the same code constraints, enhances the capacity of subwavelength optical code switched networks.

    Full Text Available Construction industry in India is second largest next to agriculture. In current era of infrastructure development construction projects occupy a key position. In any construction project contract time and cost overrun is a common feature, which gives rise to claims leading to disputes. These disputes if not handled properly tend to consume time and money of all parties to the contract. To resolve the dispute in optimum time, it is essential to understand the root cause of disputes as early as possible. Hence there is a need of analyzing the disputes scientifically.  The present study reveals from the study of arbitration awards that the causes for delay claims can be grouped in domains and the probable decisions to the disputes can be traced through the probing questions considered by decision makers. This paper attempts to identify questions related to disputes for Indian scenario through literature, arbitration awards, court cases and discussions with professionals.

    2015-01-01

    Full Text Available We refer to the problem of constructing broadcast trees with cost and delay constraints in the networks as a delay-constrained minimum spanning tree problem in directed networks. Hence it is necessary determining a spanning tree of minimal cost to connect the source node to all nodes subject to delay constraints on broadcast routing. In this paper, we proposed a genetic algorithm for solving broadcast routing by finding the low-cost broadcast tree with minimum cost and delay constraints. In this research we present a genetic algorithm to find the broadcast routing tree of a given network in terms of its links. The algorithm uses the connection matrix of the given network to find the spanning trees and considers the weights of the links to obtain the minimum spanning tree. Our proposed algorithm is able to find a better solution, fast convergence speed and high reliability. The scalability and the performance of the algorithm with increasing number of network nodes are also encouraging.

    In mid-1995 the Parti Quebecois, then in opposition, claimed evidence of influence peddling, international drug money laundering, kickbacks and fraud in Quebec`s independent power program. It also claimed evidence of irregularities at Hydro-Quebec in its procedures for approving hydropower projects. The Liberal Quebec government of the day ordered a public inquiry, led by Quebec superior court judge Francois Doyon. He submitted the Commission`s final report in April 1997. The report exonerated Hydro-Quebec and the province`s independent power industry of any criminal wrong doing regarding their respect for legal and regulatory directives and the `ethical norms and practices` of sound business management. In its 600-plus page report, the Doyon Commission found that while there was a certain lack of administrative rigor which allowed certain Hydro-Quebec executives to put themselves in questionable conflict-of-interest situations, their actions were not illegal. The current Parti Quebecois Government accepted the report and its recommendation concerning tightening conflict-of-interest guidelines. The current Liberal opposition in the National Assembly charged that the conclusions of the Commission were a foregone conclusion since the demand for the inquiry was politically motivated right from the beginning.

    Full Text Available Project delay in the construction industry is a universal or large-scale observable fact affecting not only the construction industry but the overall economy of countries too. The objective of this study is to evaluate and identify the causes and consequences of project delays in the private housing development projects in Malaysia and the remedies that can minimize these delays. An online questionnaire survey has been carried out to collect the data and this included 76 respondents from multiple developers’ companies around Malaysia. From the survey, a total of 28 causes and 6 consequences of project delays had been identified from four different factors of delays; such as client factors, consultant factors, contractor factors and external factors, by which the contractor factor being the major contributor to this problem.The top ten causes of the delays are due to weather conditions, poor site conditions, poor site management, incomplete documents, lack of experience, financial problems, contract modifications, delay in approving of major variations, contractor coordination problem with other parties and construction mistakes and defective works. The consequences of the delays would contribute to time overrun, cost overrun, different in opinions, negotiations, legal actions and total abandonment.

    In this study, Nuclear Power Plant (NPP) construction schedule delay risk assessment methodology is developed and the construction delay risk is assessed for turnkey international NPP projects. Three levels of delay factors were selected through literature review and discussions with nuclear industry experts. A questionnaire survey was conducted on the basis of an analytic hierarchy process (AHP) and Relative Importance Index (RII) methods and the schedule delay risk is assessed qualitatively and quantitatively by severity and frequency of occurrence of delay factors. This study assigns four main delay factors to the first level: main contractor, utility, regulatory authority, and financial and country factor. The second and the third levels are designed with 12 sub-factors and 32 sub-sub-factors, respectively. This study finds the top five most important sub-sub-factors, which are as follows: policy changes, political instability and public intervention; uncompromising regulatory criteria and licensing documents conflicting with existing regulations; robust design document review procedures; redesign due to errors in design and design changes; and worldwide shortage of qualified and experienced nuclear specific equipment manufacturers. The proposed combined AHP-RII methodology is capable of assessing delay risk effectively and efficiently. Decision makers can apply risk informed decision making to avoid unexpected construction delays of NPPs.

    Full Text Available Water construction projects in Iran frequently face problems which cause cost overrun and time delay, the two most common issues in construction projects in general. The objective of this survey is to identify and quantify these problems and thus help in avoiding them. This survey represents a collection of the most significant problems found in the literature, classified into 11 groups according to their source. The questionnaire form used contains 84 questions which were answered by random engineers who work in water construction projects. The Relative Importance Weight (RIW method is used to weight the importance of each one of the 84 problems. The focus of this survey is on overall top ten issues which are: bureaucracy in bidding method, inflation, economical condition of the government, not enough information gathered and surveys done before design, monthly payment difficulties, material cost changes, law changes by the government, financial difficulties, mode of financing and payment for completed work and changes made by the owner. A section for each of these issues provides additional information about them. In the full text of this survey the same weighting method is used to classify the main groups, and the results show that issues related to the groups of government, owner and consultant has the most significant impact. The last part of this survey describes the point of view of the engineers who took part in this survey and the recommendations they made.

    The participation of Hydro-Quebec International in the construction and development of the Rio Lajas hydroelectric project in Costa Rica was described. The 10 MW Rio Lajas hydroelectric station in Costa Rica is expected to go into operation in September of 1998. The station is owned by the HRL consortium, which is composed of Hydro-Quebec International and Corporacion Superior. Construction of the station was contracted out to SEH Constructora SA, a company composed of the Costarican contractor Saret and two companies from Quebec; Entreprises Bon Conseil and Hydro-Mecanique. The station comprises two horizontal-axis Francis turbines. Turbines and alternators were respectively supplied by Bouvier and GEC Alsthom, two French manufacturers. Considerable attention was given to the control of the Rio Lajas river, whose discharge can vary by as much as 100 times in the steep volcanic terrains. Approximately 15 Hydro-Quebec employees were delegated to Costa Rica to oversee various stages of the project.

    The recent formation of the Quebec Association for the Production of Renewable Energy (l`Association quebecoise de la production d`energie renouvelable - AQPER) was announced. The Association is becoming the centre of the Quebec private electricity generation industry. By communicating the industry`s message to the public the organization gives much needed visibility to renewable resources, new forms of energy and sustainable development. The new group is an outgrowth of the former Quebec Association of Private Hydroelectricity Producers. In its new reincarnation, the organization represents all forms of renewables, small and medium hydro, wind, solar, forest and agricultural biomass and urban waste. With deregulation of the electricity market, specifically the creation of the Regie de l`energie` in Quebec, the wider role is a welcome boost for renewable energy development in the province. In one of its first actions the AQPER recommended that all hydroelectric sites up to 50 MW be reserved for development exclusively by the private sector, in conformity with the Quebec energy policy announced in 1996.

    "This article addresses the way in which the Province of Quebec has obtained increasing power in the area of immigration.... Data from interviews with key members of [the Ministry of Immigration] and from selected documents are drawn on to illustrate Quebec's cultural politics. The Quebec position on the question of immigration as it has evolved in the context of immigration policies defined by the federal government in Ottawa is examined.... In particular, the present article considers how attempts to construct a cultural identity and a nation-state in Quebec have had important consequences for immigration policy and for attitudes and policies concerning Quebec's cultural minorities. The emergence of the notion of 'cultural communities' as a result of the constitutional rivalry and the on-going struggle for legitimacy between Quebec and Ottawa is also explored."

    Time in infrastructure construction projects has always been a fundamental issue as early as from the inception of a project, during the construction process and often after the completion and delivery. In a typical construction contract time related matters such as the completion date and possible delays are among the most important issues that are dealt with by the contract provisions. In the event of delay there are usually provisions for extension of time award to the contractor with possible reimbursement for the extra cost and expenses caused by this extension of time to the contract duration. In the case the contractor is not entitled to extension of time, the owner will be possibly entitled to amounts as compensation for the time prohibited from using his development. Even in the event of completion within the time agreed, under certain circumstances a contractor may have claims for reimbursement for extra costs incurred due to induced acceleration measures he had to take in order to mitigate disruption effects caused to the progress of the works by the owner or his representatives. Depending on the size of the project and the agreement amount, these reimbursement sums may be extremely high. Therefore innovative methods with the exploitation of new technologies for effective project management for the avoidance of delays, delay analysis and mitigation measures are essential; moreover, methods for collecting efficiently information during the construction process so that disputes regarding time are avoided or resolved in a quick and fair manner are required. This paper explores the state of art for existing use of Building Information Modelling (BIM) and Unmanned Aerial Vehicles (UAV) technologies in the construction industry in general. Moreover the paper considers the prospect of using BIM technology in conjunction with the use of UAV technology for efficient and accurate as-built data collection and illustration of the works progress during an

    The bending behavior of double-row stabilizing plies is associated with the constructional time delay (CTD),which can be defined as the time interval between the installations of the front stabilizing pile and the rear stabilizing pile.This paper investigates the effect of CTD on the bending moments of double-row stabilizing piles and a method for determining the optimal CTD is proposed.The stabilizing pile is modeled as a cantilever pile embedded in the Winkler elastic foundation.A triangular distributed earth pressure is assumed on the pile segment in the sliding layer.The front stabilizing pile and the rear stabilizing pile are connected by a beam with pinned joints.The analytical solutions of bending moments on the front and the rear stabilizing piles are derived and the accuracy of bending moment solutions is validated by comparing the tensile strain measured from the Hongyan landslide project,Taizhou,Zhejiang,China.It is concluded that CTD has a significant influence on the bending moments of double-row stabilizing piles.An optimal CTD can be obtained when the maximum tensile stress in the front stabilizing pile is equal to that in the rear stabilizing pile,which is 1.4 months for the Hongyan landslide project.

    The incidence of Kawasaki disease in Maghreb countries is apparently low, unlike those living in the province of Quebec, Canada. This retrospective study compared Maghrebi children living in Quebec to the countries of origin, Morocco, Algeria, and Tunisia. The annualized incidence rate in Quebec (18.49/year/100 000 children under 5 years of age) was 4 to 12 times higher than in Tunisia, Morocco, and Algeria (0.95, 4.52, and 3.15, respectively). The prevalence of incomplete diagnostic criteria was higher in Quebec at 39%, Morocco 43%, and Tunisia 39% compared to Algeria at 8%, with minimal delayed diagnosis (7%) only in Quebec compared to 30%, 35%, and 62%, respectively (P disease in the Maghreb community in Quebec versus the countries of origin seems due to underdiagnosis, which represents a public health concern in those countries.

    2011-07-15

    The southern part of Quebec has reserves of terrestrial heat sufficient to justify deep geothermal heat extraction operations. Deep geothermic technology taps the Earth's internal heat at depths of up to several kilometers and transfers it to the surface by means of a heat-bearing fluid. This heat is an abundant, clean and renewable source of energy and is, moreover, continuously available at all times unlike other renewable energy sources, while the operating installations occupy only a negligible land surface area. Nevertheless, certain issues remain, notably with respect to the generation of microseismic noise as well as issues of popular and political support for the technology. Advances in the technology are likewise needed to develop improved tools and optimize water-use. Quebec has a significant source of energy located in its most heavily populated region, which facilitates transport, and which could open up the possibility of energy security for the province.

    2001-10-01

    Recent changes in the organization and policies of Hydro-Quebec, which could place the utility giant in front and centre of a possible North American energy common market, are discussed. In this context, the discussion covers the development of the La Grange hydroelectric development in the 1970s and 1980s, the subsequent signing of long-term export contracts with large power grids in the United States, and the more recent developments in opening up of electricity markets. Some implications of these changes, such as the marketing of electricity on electronic stock exchanges at prices that move in step with supply and demand (spot pricing), the establishment of separate generating, transmission and distribution divisions, and the introduction of new operating procedures designed to satisfy the new rules of reciprocity between liberalized electricity markets, are also described. As part of this new set of marketing tools Hydro-Quebec is planning to construct a $185-million power line between Connecticut and Long Island through its subsidiary, TransEnergy US, to boost transmission capacity, which will be allocated by secondary transmission rights. These rights can be sold and traded in financial markets, the first such undertaking in the United States. Unlimited access to US markets for Hydro-Quebec will be also facilitated by Bill 116, enacted by the Quebec Legislature in June 2000, which will give US utilities access to the Quebec wholesale market. These, and other changes of similar magnitude will radically change the energy supply landscape and open up the electricity market in the province to the outside world more than ever in the past. 5 photos.

    Health or disease management (DM) has emerged as a promising solution to improve the quality of healthcare and patient outcomes in a cost-efficient way. This solution is particularly relevant in the care of our increasing, and aging, patient populations with multiple chronic diseases. This article reviews the recent history and current status of DM in the province of Quebec and summarizes its evolving perspectives and future prospects. Most DM projects in Quebec have developed from a public-private partnership, and they have addressed several disease states. The results of completed programs confirmed the presence of care gaps--the differences between best and usual care in several disease states. They also identified process changes leading to improved practices and enhanced professional satisfaction among stakeholders. Priorities identified for further research include increased knowledge of the underlying causes of care gaps and greater concentration on the measurement of clinical, humanistic and fiscal outcomes and their causal links to DM structures and processes. Although still embryonic in Quebec and Canada, the available evidence suggests that DM partnerships are practical and functional vehicles to expedite knowledge creation and transfer in the care of whole populations of patients. Future projects offer the promise of updated knowledge and continuously improved care and outcomes.

    2013-07-01

    Full Text Available The time for performance of a project is usually of the essence to the employer and the contractor. This has made it quite imperative for contracting parties to analyse project delays for purposes of making right decisions on potential time and/or cost compensation claims. Over the years, existing delay analysis techniques (DATs for aiding this decision-making have been helpful but have not succeeded in curbing the high incidence of disputes associated with delay claims resolutions. A major source of the disputes lies with the limitations and capabilities of the techniques in their practical use. Developing a good knowledge of these aspects of the techniques is of paramount importance in understanding the real problematic issues involved and their improvement needs. This paper seeks to develop such knowledge and understanding (as part of a wider research work via: an evaluation of the most common DATs based on a case study, a review of the key relevant issues often not addressed by the techniques, and the necessary improvements needs. The evaluation confirmed that the various techniques yield different analysis results for the same delay claims scenario, mainly due to their unique application procedures. The issues that are often ignored in the analysis but would also affect delay analysis results are: functionality of the programming software employed for the analysis, resource loading and levelling requirements, resolving concurrent delays, and delay-pacing strategy. Improvement needs by way of incorporating these issues in the analysis and focusing on them in future research work are the key recommendations of the study.

    An historical overview of the James Bay Hydroelectric Power Development in northern Quebec was provided. The account touches upon the foundation of the Societe d`energie de la Baie James, a wholly-owned subsidiary of Hydro-Quebec. It describes the La Grande Complex, and provides a brief summary of the site investigation, the geological and geotechnical considerations, the rock excavation, the construction of embankments and dikes, and nature of the bedrock and overburden foundations. Some of the more interesting problems that arose during the construction such as the settling of the crest in the protective islands surrounding the instruments at some of the dam sites were outlined. Leakage under some of the La Grande 3 low head dikes near the end of the reservoir filling period and the degradation of some of the riprap protection of the Phase One embankments were also described. The solutions designed to overcome these problems were also part of the account of this major mega development project that promoted Quebec into the ranks of the major hydro energy producers in North America. 11 refs., 2 tabs., 3 figs., photos.

    Until recently, Quebec was the first to have regulated the practice of psychotherapy through law adopted in 2009. The law emerged following 30 years of efforts and inter-professional discussions that led to a consensus by an expert committee presided by Dr Jean-Bernard Trudeau in 2005. In this essay, Dr Jean-Bernard Trudeau, general practitioner, and two psychiatrist and psychologist colleagues, who have participated to the expert committee or have been involved more recently in the implementation of law no 21 in Quebec, relate the main landmarks and moments in the regulation of the practice in psychotherapy following this inter-professional consensus that was translated in the law 21. They relate particularly the last ten years that have led to the adoption of law 21 in 2009, following two parliamentary commission after the Trudeau report. They underline how the practice of psychotherapy is integrated in the professional system and submitted to strict regulation. It includes regulations for obtaining the license of psychotherapist and for maintaining competence. Guidelines emerging from continuous inter-professional discussions for the application of the law and of its regulation in the public and private sectors are produced by the Quebec Professions Office. The definition of psychotherapy that was reached by consensus is not limited to the treatment of mental disorders and is distinguished from other intervention in the area of human relations. Continuous training is mandatory and is implemented on one hand by the Order of the psychologists for the psychologists and other professionals practicing psychotherapy and on the other hand the College of physicians for physician practicing psychotherapy.

    Full Text Available According to the multi-project and program management theory, this paper analyzes the program generation principle and establishes a program based on progress goals. On the basis of the present situation of calculation of penalty for delay of the bidding section construction period with the critical path method, we studied the effects of contractor-induced delay of the bidding section construction period in detail, including the effects on the construction period of the bidding section itself, the earliest start times of the next bidding section and other subsequent bidding sections, and the construction period of the program, and then constructed a penalty model for delay of the bidding section construction period from the perspective of programs. Using the penalty model, we conducted a practical analysis of penalty for delay of the construction period of the Baoying station program in the South-to-North Water Diversion Project. The model can help determine the amount of penalty for delay of the construction period in bidding sections scientifically and reasonably.

  6. Stray voltage zapping cows, pigs in Quebec

    Energy Technology Data Exchange (ETDEWEB)

    1988-05-18

    A power-supply malfunction is giving farm animals in Quebec a shock every time they eat or drink from metal troughs, making them nervous, lowering production, and stunting growth. In 2 years of negotiation with Hydro-Quebec, the utility has refused to correct the problem known as stray voltage. The shocks measure about 10 volts. It has been estimated the average Quebec dairy farmer with 40 cows is losing $15,000 to $20,000/y in reduced milk production. About 4,000 of the 23,000 Quebec pig and dairy farms are bothered by stray voltage. Hydro-Quebec has been asked to install filters that would reduce the problem; however, Hydro-Quebec attributes the stray voltage to the farmers' own equipment. A study conducted by the provincial Agriculture Department that measured stray voltage on 700 farms showed that 70% of the problem was Hydro-Quebec equipment. Farmers are prepared to solve the remaining 30% themselves.

    1995-12-31

    This book provides an overview of the past history and expected future development of Hydro-Quebec through a series of papers presented at a conference in Montreal in 1994. The papers focus on six principal themes: (1) fifty years of history and symbolism, (2) stakes and future choices,(3) economic development and innovation, (4) Quebec northern policy, (5) energy choices and the environment, and (6) the issue of privatizing Hydro-Quebec. The intimate relationship of Hydro-Quebec, long perceived as the major pillar of the economic development of Quebec, and fundamental to the evolution of the idea of a Quebec nation, were also explored. Although the historical approach was clearly preferred by most of the contributors, the uncertain future of the giant utility in the face of the continent-wide movement towards competition and open access, received the bulk of the attention. The special complications introduced by the resistance to hydroelectric power development of Quebec`s native population, environmental concerns, and the quest for sustainable development, also have been treated extensively. refs., tabs., figs.

    Full Text Available This article aims to reconstruct the history of civil society in Quebec (Canada to relate it with nationalism, the rise of the welfare state, trade unions, Catholic Church and civil society, the dynamic forces of society. Through in-depth interviews with key leaders, exploration of institutional archives and specific literature, we work with a particular case that, when compared to Catalonia, will allow us to evaluate the importance of civil society within nationalism. This actor is not usually considered as the central subject of researches and rarely token into account, unlike political parties, their leaders or intellectuals. Currently, in a context of crisis of the state and political parties, it has begun to be considered that civil society can be a key factor for its ability to produce alliances between sectors, build hegemony and dialogue directly with the population. The study is divided into four parts: 1 the development of the theoretical framework along with the construction of the object of study and the hypotheses; 2 an analysis about the importance of the involvement of civil society in the construction of the nationalist movement in Quebec; 3 a comparison with the Catalan case; and, 4 finally some conclusions.

  13. Mergers and integrated care: the Quebec experience

    Directory of Open Access Journals (Sweden)

    Louis Demers

    2013-02-01

    Full Text Available As a researcher, I have studied the efforts to increase the integration of health and social services in Quebec, as well as the mergers in the Quebec healthcare system. These mergers have often been presented as a necessary transition to break down the silos that compartmentalize the services dispensed by various organisations. A review of the studies about mergers and integrated care projects in the Quebec healthcare system, since its inception, show that mergers cannot facilitate integrated care unless they are desired and represent for all of the actors involved an appropriate way to deal with service organisation problems. Otherwise, mergers impede integrated care by creating increased bureaucratisation and standardisation and by triggering conflicts and mistrust among the staff of the merged organisations. It is then preferable to let local actors select the most appropriate organisational integration model for their specific context and offer them resources and incentives to cooperate.

The higher incidence of Kawasaki disease in the Maghreb community in Quebec versus the countries of origin seems due to underdiagnosis, which represents a public health concern in those countries.

    In response to growing energy demands, Quebec has proposed the construction of 3 deep water terminals to accommodate methane tankers which transport liquefied natural gas (LNG). This paper focused on the proposed Gros Cacouna Port project in the St. Lawrence Seaway which is currently under study and subject to approval. Equiterre, questioned the energy security aspect of the proposal and argued that increasing Quebec's reliance on increasingly expensive energy would decrease energy security. In addition, importation of LNG would bring a clear exit of capital outside the province. Equiterre also argued that reliance on fossil fuels should be decreased in order to mitigate greenhouse gas emissions which contribute to climate change. The organization questioned whether the economic and social need for the proposed project justifies a greater dependency on fossil fuels and the associated impact on the environment and fragile ecosystems of the St. Lawrence. It was suggested that alternative solutions such as renewable energy sources and energy efficiency should be explored in order to promote sustainable development, increase energy security and reduce greenhouse gases. Equiterre argued that Quebec can and must decrease, and even eliminate, its dependence on fossil fuels, including natural gas, for Quebec's economic, social and environmental well-being. For these reasons, Equiterre recommended that the proposed project be rejected, particularly since the project proponents failed to show the real impact that the project would have on Quebec markets. 72 refs., 10 tabs., 21 figs.

    Understanding effects of location and timing of harvest seasons on mortality of ducks and geese from hunting is important in forming regulations that sustain viable waterfowl populations throughout their range. During 1990 and 1991 we alternately marked 80 hatching year (HY), female mallards along the Vermont–Quebec border; half with radio-transmitters and bands and half with only aluminum leg bands. We monitored radio-marked ducks daily and recorded survival status weekly for 15 weeks from August until December each year. Mallard mortalities began 25 September when the hunting season opened in the Province of Quebec, Canada. Overall survival of mallards at week 10 did not differ between years (0.51 in 1990 vs. 0.43 in 1991) or differ from that of HY American black ducks (0.44 females, 0.42 males) based on proportional hazard analysis in a Bayesian framework. The mortality rates for mallards from hunting (0.47) and causes unrelated to hunting (0.06) were similar between years and to those rates for HY black ducks at that same site. Hunter harvest accounted for most of the mortality recorded during this study and illegal feeding (i.e., baiting) at sites just before and during the hunting season was observed. Females with lower body condition index had greater mortality rates; a 1-standard-deviation increase in condition index would reduce mortality hazard by about 29%. Management options that may increase mallard survival in the area include lowering daily bag limit in Quebec and suspending split hunting seasons in Vermont that increase harvest, delaying opening date of hunting in Quebec to allow for increased body condition before hunting season opens, and improving enforcement of baiting restrictions.

    This is a retrospective study on wild raptors submitted to the Université de Montréal (Quebec, Canada) from 1989 to 1996. Cyathostoma spp. (Nematoda: Syngamidae) adults and/or eggs were found in air sacs, lungs, bronchi, and trachea of 12 raptors (Falconiformes and Strigiformes) from Quebec, Canada, belonging to eight different species, five of which are first host records for this parasite: barred owl (Strix varia), snowy owl (Nyctea scandiaca), northern harrier (Circus cyaneus), northern goshawk (Accipiter gentilis), and broad-winged hawk (Buteo platypterus). The infection was considered fatal in four birds, while no significant clinical signs were observed in the other cases. Major pathologic changes included diffuse pyogranulomatous air sacculitis, pneumonia, and bronchitis. A few unidentified larval nematodes embedded in a granuloma were found in the lungs of an additional Coopers' hawk (Accipiter cooperii); they were not considered clinically significant. A dead nematode, surrounded by necrotic inflammatory cells, was found in the air sac of a northern goshawk. The presence of nematodes in air sacs or lungs should be considered in wild raptors demonstrating respiratory problems.

    Date of completion is usually set forth in construction contract agreements as one of the most important provisions. Also, it is the provision, which is often violated and the violation results in a dispute between the parties to the agreement. Analysis of research literature has revealed that most authors analyse and identify causes of delays in construction as well as recommend delay analysis methods omitting or underemphasising the liability of the parties to construction contract agreements for violation of construction completion date. One more problem in this area is the difficulty in applying practices of different countries in a specific country due to differences in legislative frameworks. Cases described in research literature are often idealised, while realistic construction projects frequently possess various specific features. This article aims at identifying problems faced when assessing the liability of construction participants for violation of completion date and suggesting ways to handle the problem.

  5. Hydro-Quebec seeks open access in the US

    Bright, D.; Salaff, S.

    1996-02-01

    Issues relevant to a recent U.S. Federal Energy Regulatory Commission (FERC) order to Hydro-Quebec to open up access to its transmission system, as a condition of participation by a Hydro-Quebec subsidiary in energy marketing in the United States, were outlined. Hydro-Quebec was reported to be considering its options, and has not yet responded to the order. Hydro-Quebec currently sells its energy at the US border in all export transactions. With the approval of FERC, Energy Alliance Partnership would be in a position to offer its customers choices in selling, buying, borrowing and loaning natural gas , electricity and other fuels, as a wholesaler in the electricity and natural gas business. FERC was concerned that by allowing greater market penetration by Hydro-Quebec and its partners could lead to generation dominance, or affiliate abuse. Hydro-Quebec`s position is that transmission constraints and legal limitations, as well as Hydro-Quebec`s obligation to serve its own provincial load, are extremely unlikely to allow its current 10% share of the U.S.market to increase significantly in the foreseeable future.

    OBJECTIVE: To estimate the prevalence of questionable and rational high-risk prescribing among elderly people of the three drug groups most commonly implicated in drug-related illness: cardiovascular drugs, psychotropic drugs and nonsteroidal anti-inflammatory drugs (NSAIDs). DESIGN: Retrospective prevalence study; all prescription and billing records for the period Jan. 1 to Dec. 31, 1990, for the study sample were retrieved from the relevant provincial databases of the Régie de l'assurance-maladie du Québec. SETTING: Quebec. PARTICIPANTS: Regionally stratified random sample of 63,268 elderly medicare registrants who made at least one visit to physician in 1990 and were not living in a health care institution for the entire year. MAIN OUTCOME MEASURE: Prescription information was examined for three types of high-risk prescribing: rational and questionable drug combinations, excessive treatment duration and drugs relatively contraindicated for use in elderly people. RESULTS: Overall, 52.6% of the patients experienced one or more events of high-risk prescribing, and 45.6% experienced at least one that was questionable. High-risk prescribing was most prevalent for psychotropic drugs, and questionable prescribing was more frequent than rational prescribing in this drug group. An estimated 30.8% of the total elderly population in Quebec received benzodiazepines for more than 30 consecutive days, 12.9% received a long-acting benzodiazepine, and 13.0% received a questionable high-risk psychotropic drug combination. The prevalence of high-risk prescribing was higher among the women than among the men and increased with age until 75 to 84 years. There were significant unexplained differences between regions in the regional prevalence of high-risk prescribing, particularly of psychotropic drugs. CONCLUSION: The prevalence of questionable high-risk prescribing, especially of psychotropic drugs, is substantial among elderly people. This may be a potentially important and

    A case study of state corporations in the forestry, mining, and petroleum sectors in resource frontier regions reveals the extent of state involvement in infrastructure and production in Quebec. The intention of government corporations was to encourage Quebec enterprise, to promote resource extraction in hinterland regions, and to contribute to the ''economic liberation'' of Quebec, as part of a regional policy of ''maitres chez nous.'' A complex set of relationships involving regional and international investments, ideology, and economic nationalism are discussed for the period 1960-1980. It is concluded that the state has become an integral part of regional development in selected resource frontier regions in Quebec.

We conducted a survey using a questionnaire assessing the social acceptance of and confidence level in telehealth. Two strategies were used: 1) paper questionnaires were sent to two hospitals in Quebec; and 2) online questionnaires were randomly sent by a firm specialized in online survey to a representative sample of the population of the Province of Quebec. Respondents were all residents of the Province of Quebec and 18 years and older. Questions were scored with a four-level Likert scale. A total of 1816 questionnaires were analyzed (229 written and 1,587 online questionnaires). The socio-demographic variables in our samples, especially the online questionnaires, were fairly representative of Quebec's population. Overall, social acceptance scored at 77.71% and confidence level at 65.76%. Both scores were higher in the case of treatment (3 scenarios were proposed) vs. diagnosis (p < 0.05). No difference was found when respondents were asked to respond for themselves and for a member of their family, which demonstrates a true interest in telehealth in Quebec. In addition, we found a significant difference (p < 0.05) between written and online questionnaires regarding social acceptance (80.75% vs. 77.33%) and confidence level (74.84% vs. 64.55%). These differences may be due to social desirability or avidity bias in the written questionnaires. Our results suggest that the population in Quebec encourages the development of telehealth for real time diagnosis and long distance treatment for regions deprived of healthcare professionals.

    Full Text Available Fertilizer recommendations for cranberry crops are guided by plant and soil tests. However, critical tissue concentration ranges used for diagnostic purposes are inherently biased by nutrient interactions and physiological age. Compositional data analysis using isometric log ratios (ilr of nutrients as well as time detrending can avoid numerical biases. The objective was to derive unbiased nutrient signature standards for cranberry in Quebec and compare those standards to literature data. Field trials were conducted during 3 consecutive years with varying P treatments at six commercial sites in Quebec. Leaf tissues were analyzed for N, P, K, Ca, Mg, B, Cu, Zn, Mn and Fe. The analytical results were transformed into ilr nutrient balances of parts and groups of parts. High-yield reference ilr values were computed for cranberry yielding greater than 35 Mg ha-1. Many cranberry fields appeared to be over-supplied with K and either under-supplied with Mn or over-supplied with Fe as shown by their imbalanced [K | Ca, Mg] and [Mn | Fe] ratios. Nutrient concentration ranges from Maine and Wisconsin, USA, were combined into ilr values to generate ranges of balances. It was found that these nutrient ranges were much too broad for application in Quebec or outside the Quebec ranges for the [Ca | Mg] and the [Mn | Fe] balances, that were lower compared to those of high yielding cranberry crops in Quebec.

  19. Private Life and Collective Experience in Quebec: The Autobiographical Project of France Théoret

    Directory of Open Access Journals (Sweden)

    Mary Jean Green

    1993-01-01

    Full Text Available In her study of women's autobiographical writing, Carolyn Heilbrun contends that women's authorship has been most hindered by the lack of narrative structures adequate to the telling of women's experience. She further suggests that female narrative will be found as women talk together, exchange stories, and move toward a collective understanding of self. In recent years, the interplay of women's voices has assumed new importance in women's writing, and specifically in women's life/writing in French. Perhaps beginning with Simone de Beauvoir's feminist classic, The Second Sex , where the words of hundreds of other women are woven into the text to form an understanding of the shape of a woman's life, this new form of women's narrative is apparent in the autobiographical project of the Quebec Francophone writer France Théoret. In her novel Nous parlerons comme on écrit , the interplay of different voices and the interlocking and mirroring of disparate narratives enable Théoret to construct a female autobiographical subject that encompasses the reality of several generations of Quebec women. Théoret's work is thus, like that of the Algerian Francophone writer Assia Djebar, an example of a new narrative form that has emerged from women's collective efforts to construct a new female self, a sort of feminist collective autobiography.

    The growing concern regarding the long-term contribution of freshwater reservoirs to atmospheric greenhouse gases (GHG), led Hydro-Quebec, to study net GHG emissions from Eastmain 1 reservoir, which are the emissions related to the creation of a reservoir minus those that would have been emitted or absorbed by the natural systems over a 100-year period. This large study was realized in collaboration with University du Quebec a Montreal, McGill University and Environnement IIlimite Inc. This is a world premiere and the net GHG emissions of EM-1 will be presented in details.

    Full Text Available Very few Streptococcus suis infections in humans have been reported in Canada, although the condition is frequent in pigs. Meningitis, often accompanied by severe hearing loss, is the most common clinical manifestation. The disease is an occupational illness affecting persons in contact with pigs and may be underdiagnosed because of misidentification of the responsible bacterium. Since Quebec is the leading province for swine production in Canada, physicians and microbiologists should be aware of this infection, especially when a streptococcal meningitis is diagnosed in swine workers. The first case of S suis type 2 meningitis reported in Quebec is described.

  4. Socioeconomic fertility differentials in a late transition setting: A micro-level analysis of the Saguenay region in Quebec

    Directory of Open Access Journals (Sweden)

    Hélène Vézina

    2014-04-01

    Full Text Available Background: Historically, the French Canadian population of Quebec, Canada, is known for its high fertility, which lasted well into the 20th century, and for its late fertility transition. Within Quebec, regions such as Saguenay are known for having experienced an even more delayed fertility transition. Objective: In Quebec, as elsewhere, various factors modulated the transition, and differential behaviors and timing can be observed across socioeconomic groups. These factors are studied here in the context of the Saguenay region, where particularly rich data are available. The region was mostly rural at first, but industrialization and urbanization occurring since the beginning of the 20th century allow us to study socioeconomic reproductive differentials before and during the transition. Methods: To do so, we rely on the BALSAC database, which contains all church and civil records from the onset of colonization around 1840 up to 1971. In addition to the usual descriptive statistics, we use Cox models to analyze the probability of having a first birth and higher order births among four socioeconomic groups defined with HISCLASS coding. Results: The results demonstrate the late timing of the transition and a clear progression from the non-manual and skilled workers, who show the first signs of declining fertility during the 1930s, to the farmers, who do the same only at the end of the 1950s. As a result, socioeconomic fertility differentials widened during the transition period. Conclusions: Even in a context where the transition was significantly delayed compared to most other regions studied in this issue, some socioeconomic differentials were observed prior to the transition, and they widened during the transition due to the differential progression of contraceptive practices among couples.

    Vivre en Ville is a group of 225 activists from Quebec's health, environment, transportation and education sectors that promote sustainable living in the urban areas of the province. Their recommendations to save energy are based on principles of energy efficiency and combining resources to promote the use of common transportation corridors, diversified urban living and the protection and renovation of heritage sites. In addition to promoting the creation of parks and green spaces in urban areas, the group encourages residents to engage in municipal affairs by demanding solutions to transportation problems. Among their recommendations are a moratorium on the construction of new highways; upgrade existing mass transit systems to minimize personal vehicle use; increase funding for public transport; promote light rail transit to suburban areas; and devote special road lanes to collective transport such as taxis, buses and car pools. Other recommendations include the creation of more bicycle paths and centres that offer bikers shower and locker facilities. The group also believes that companies with more than 30 employees should be required to have transportation policies for its employees, such as organized car pools. Vivre en Quebec claims that too much energy has already been wasted and more action should be taken to implement these recommendations. tabs.

  16. Strategies for the development of Quebec`s petrochemical industry: education and environment

    Energy Technology Data Exchange (ETDEWEB)

    O`Connor, J.A. [Canadian Chemical Producer`s Association (Canada)

    1992-12-31

    One of the key challenges not only for the Quebec but for the Canadian petrochemical industry will be the challenge to increase the number of students pursuing science or engineering as fields of study. According to this author, there is a crisis in science and technology education in Canada. The ability of Canadian students to compete with their peers around the world is steadily diminishing as a result of the undue emphasis on student attitudes and self-esteem in Canadian schools, as opposed to European and Asian schools which focus on conveying specific skills. He advocates a shift in attitude away from simply more money spent on education towards concern with what and how well students are learning. It was suggested that the educational system must take into account the demands of the market place in fashioning the curricula. If students are to function in the real world where performance is evaluated, the educational system will have to change to reflect the fact that the market and society reward people in proportion to their contribution. The relationship between environmental concern and education was also explored, and the inclusion of environmental issues in the classroom curriculum was recommended. As a topic for curricula, the environment is subject to broad-ranging and often conflicting views regarding its problems and their causes, effects and remedies. Nevertheless, it is not a transient issue to be dismissed as a fad. Rather, it is an issue here to stay, hence it should play a more formalized role at all levels of the curriculum from primary schools to colleges and universities.

    Delayed fission is a nuclear decay process that couples {beta} decay and fission. In the delayed fission process, a parent nucleus undergoes {beta} decay and thereby populates excited states in the daughter. If these states are of energies comparable to or greater than the fission barrier of the daughter, then fission may compete with other decay modes of the excited states in the daughter. In this paper, mechanism and some experiments of the delayed fission will be discussed. (author)

    This study evaluates implementation of the Quebec Mental Health (MH) Reform (2005-2015) which aimed to improve accessibility, quality and continuity of care by developing primary care and optimizing integrated service networks. Implementation of MH primary care teams, clinical strategies for consolidating primary care, integration strategies to improve collaboration between primary care and specialized services, and facilitators and barriers related to these measures were examined. Eleven Quebec MH service networks provided the study setting. Networks were identified in consultation with 20 key MH decision makers and selected based on variation in services offered, integration strategies, best practices, and geographic criteria. Data collection included: primary documents, structured questionnaires completed by 25 managers from MH primary care teams and 16 respondent-psychiatrists working in shared-care, and semi-structured interviews with 102 network stakeholders involved in the reform. The study employed a mixed method approach, triangulating the three data sources across networks. While implementation was not fully achieved in most networks, the Quebec reform succeeded in improving primary care services with the creation of adult primary care teams, and one-stop services which increased access to care, mainly for clients with common MH disorders. In terms of clinical strategies implemented, the functions provided by respondent-psychiatrists had a greater impact on the MH primary care teams than on general practitioners (GPs) in medical clinics; whereas the implementation of best practices were indirect outcomes of another reform developed simultaneously by the Quebec substance use disorders program. The main integration strategies used for increasing continuity of care and collaboration between primary care and specialized services were those involving fewer formal procedures such as referrals between teams and organizations.

    This article presents the main findings of a descriptive study inventorying public health research in Quebec funded by provincial and federal government bodies between 1999 and 2004. The database was created specifically for this project from the Banque de la recherche sociale et en santé (Health and Social Research Databank) of the Quebec Ministry of Health and Social Services, using a frame of reference to demarcate and categorize research in public health. The results reveal that public health research projects accounted for 13.6% of all projects in the aforementioned database, and were mainly concentrated in the research categories Population Health and Wellness and their Determinants (Etat de santé et de bien-être de la population et ses déterminants) (59.9% of public health projects) and Social Development, Adjustment and Integration (Développement, adaptation et intégration sociale) (44.9% of public health projects). The provincial government funded a higher percentage of projects (59%), but with the exception of scholarships and fellowships, the federal government funded a higher dollar amount. Overall, funding allotted to research in public health was lower than that for other types of research in health and social sciences inventoried in the database. This first inventory of public health research in Quebec provides a means of estimating the volume of research devoted to this field and funding directed to it in comparison with other fields of research in health and social sciences. It also raises questions on the orientation, organization and funding of research in public health.

  5. Native American admixture in the Quebec founder population.

    Directory of Open Access Journals (Sweden)

    Claudia Moreau

    Full Text Available For years, studies of founder populations and genetic isolates represented the mainstream of genetic mapping in the effort to target genetic defects causing Mendelian disorders. The genetic homogeneity of such populations as well as relatively homogeneous environmental exposures were also seen as primary advantages in studies of genetic susceptibility loci that underlie complex diseases. European colonization of the St-Lawrence Valley by a small number of settlers, mainly from France, resulted in a founder effect reflected by the appearance of a number of population-specific disease-causing mutations in Quebec. The purported genetic homogeneity of this population was recently challenged by genealogical and genetic analyses. We studied one of the contributing factors to genetic heterogeneity, early Native American admixture that was never investigated in this population before. Consistent admixture estimates, in the order of one per cent, were obtained from genome-wide autosomal data using the ADMIXTURE and HAPMIX software, as well as with the fastIBD software evaluating the degree of the identity-by-descent between Quebec individuals and Native American populations. These genomic results correlated well with the genealogical estimates. Correlations are imperfect most likely because of incomplete records of Native founders' origin in genealogical data. Although the overall degree of admixture is modest, it contributed to the enrichment of the population diversity and to its demographic stratification. Because admixture greatly varies among regions of Quebec and among individuals, it could have significantly affected the homogeneity of the population, which is of importance in mapping studies, especially when rare genetic susceptibility variants are in play.

    NB Power was faced with major financial and technical challenges in generation that would lead to significant rate increases over several years to come. In 2009, the governments of New Brunswick and Quebec proposed an agreement whereby Hydro-Quebec would acquire most of the assets of NB Power and provide a guaranteed electricity supply at a set price to the province. The proposal involved the sale of NB Power's hydro generation facilities, 2 diesel peaking plants and the Point Lepreau nuclear generating facility. It also included a guaranteed bulk electricity supply of 14 Terawatt-hours per year by Hydro-Quebec at a blended rate of 7.35 cents per kilowatt-hour. The new Brunswick government would retain ownership of the fossil-fuelled power plants, the NB Power transmission assets and the NB Power distribution assets and customer sales. A 6-person independent panel was asked to examine the proposal. This report addresses the proposed agreement as presented to the Panel up to January 26, 2010. The panel conducted an independent and objective examination of the financial implications; long-term effects on electricity rates; New Brunswick's control of energy policies; environmental impacts; short-and long-term risks and avoided risks; and benefits and costs to the provincial economy. The Panel drew its conclusions and recommendations on the basis of available information. The Panel concluded that the benefits to New Brunswick contribute to real and positive value to New Brunswick over business as usual. tabs., figs.

    2010-01-01

    We address in this paper the approximation problem of distributed delays. Such elements are convolution operators with kernel having bounded support, and appear in the control of time-delay systems. From the rich literature on this topic, we propose a general methodology to achieve such an approximation. For this, we enclose the approximation problem in the graph topology, and work with the norm defined over the convolution Banach algebra. The class of rational approximates is described, and a constructive approximation is proposed. Analysis in time and frequency domains is provided. This methodology is illustrated on the stabilization control problem, for which simulations results show the effectiveness of the proposed methodology.

    Compared to the independent analysis of contractor-risk and owner-risk delay events, integrated analysis for all delay events using CPM( critical path method) scheduling techniques will have different results which are called the phenomenon of superposition effect and divergent effect. Root causes of this phenomenon are discussed in detail in this paper. Superposition and divergent effect are closely related to the reuse of total float and newly created total float time for both the contractor and the owner. Under current scheduling practices, total float is considered to be an asset for both the contractor and the owner to use for free. Newly created total float is produced by project delays caused by the contractor or the owner. Based on the consideration of the ownership and utilization of total float and newly created total float, the principle for the allocation of the outcome of superposition and divergent effect has been proposed. The new concept makes a direct response to the focus of disputes for superposition and divergent effect. Calculation methods for the allocation of delay responsibility are proposed.%针对利用网络分析技术计算工期索赔时常发生的叠加和发散效应,分析了网络计算叠加效应和发散效应的成因,得出了网络计算叠加效应和发散效应分别产生于初始时差和过程时差重复利用的结论.提出了多事件干扰下工期拖延责任分摊原则和计算方法.该方法认为时差应为承包商和业主双方共同所有,直接针对双方因时差优先使用权产生的争议,即网络计算叠加效应和发散效应产生的附加值.当在时差的使用上不发生争议时,任何一方都可以随意使用时差.如果发生争议,则争议时差应在业主和承包商之间平均分摊.该方法坚持了公平原则,很大程度上化解了承包商和业主之间的争议,同时对共同延误也具有适用性.

    Three-hundred thirty-two cases of pleural diffuse malignant mesothelioma (DMM) seen at large centers in Ontario and Quebec from 1965 to 1984 were reviewed retrospectively. Previous asbestos exposure was found in 44% of patients. Diagnosis was most often made by exploratory thoracotomy; pleural biopsy or cytology were rarely contributory. The delay in diagnosis was often long (median time, 3.5 months) and thrombocytosis (platelets greater than or equal to 400,000/microL) was common (41% of cases). The median survival (MS) was only 9 months. Eleven clinical variables were analyzed for prognostic significance. The three most important prognostic factors using a univariate analysis were stage, weight loss, and histologic type. For 118 patients with complete data, multivariate analysis showed that the stage of disease, high platelet count, and asbestos exposure were the most important prognostic factors. There was no cure of DMM, and we did not find any drastic differences in survival among groups of patients subjected to the different therapeutic measures. Radical surgery and radiotherapy were ineffective and we confirmed the low response rate to chemotherapeutic agents. This large retrospective trial can serve as a baseline for future studies in this field. In particular, it provides the basis for appropriate stratification variables to be used in future therapeutic trials.

  12. Protection strategies for drinking groundwater sources in small Quebec municipalities.

    2008-07-01

    Awareness of groundwater protection has increased substantially in recent decades. In the Province of Quebec, Canada, the Groundwater Catchment Regulation (GWCR) was promulgated in 2002 to protect water quality in public wells. The goal of the present study was to document groundwater protection in the context of emerging regulations and identify factors explaining the propensity of municipalities applying protection strategies. Two types of information were used in this study: data from a questionnaire-based survey conducted among 665 municipalities in the Province of Quebec and complementary information gathered from various sources. Data from the survey revealed that fewer than half of the municipalities have been able to comply with the GWCR, mainly because of financial limitations. Also, close to half of the municipalities have either identified or are expecting land use conflicts to arise between protection areas required by the GWCR and other land usage, with agriculture being the main conflicting activity. Multivariate logistic regression models served to identify factors explaining the likelihood of municipalities to take groundwater protection measures. Those factors were municipality revenue, history of water contamination in distribution systems, land use near wellheads, location of municipalities within a provincial priority watershed and the importance of groundwater use in a region. Results of the study may prove helpful for government authorities in better understanding the groundwater protection issue and in implementing strategies that improve the ability of municipalities to protect groundwater.

    The Quebec Longitudinal Study of Kindergarten Children (QLSKC) is an ongoing population-based prospective longitudinal study presently spanning ages 6-29 years, designed to study the prevalence, risk factors, development and consequences of behavioural and emotional problems during elementary school. Kindergarten boys and girls attending French-speaking public schools in the Canadian province of Quebec during the 1986-87 and 1987-88 school years were included in the cohort: 2000 children representative of the population and 1017 children exhibiting disruptive behaviour problems. To date, 12 waves of data have been collected, and three generations of participants have been involved in the study (i.e. the study child, his parents and the first child of the study child). Information on demographics, psycho-social and lifestyle factors, child and family member characteristics (physical and mental health), and outcomes such as psychiatric diagnoses, delinquency or school diploma were assessed during three important developmental stages (childhood, adolescence and early adulthood). Blood samples were also collected in early adulthood for genetic analyses.

    Objective: The Substance Use Risk Profile Scale (SURPS) has been developed to screen personality risk factors for substance misuse. This scale assesses 4 high-risk personality traits using a 23-item, self-report questionnaire. SURPS helps guiding targeted approaches to prevention of substance abuse and misuse. It has been validated in the United Kingdom, English Canada, Sri Lanka, and China. This study aims to validate this scale in a sample of French-speaking adolescents from Quebec as well as its sensitivity in a clinical sample of adolescents. Method: Two hundred two 15-year-old youths from a community sample completed a French version of SURPS as well as other measures of personality and substance use. This study reports the internal consistency and concurrent validity of the scale, as well as a factor analysis of items. Further, 40 youths (mean age 15.7 years) from a clinical population completed SURPS and their scores were compared with those of the community sample. Results: SURPS French translation has good internal consistency and demonstrated a 4-factor structure very similar to the original scale. The 4 subscales show good concurrent validity, and 3 of the subscales were found to correlate with measures of substance use. Finally, 95% of the clinical sample was identified at high risk for substance misuse according to SURPS cut-off scores. Conclusion: SURPS French translation seems to be a valid and sensitive scale that can be used in a French-speaking adolescent population from Quebec.

    1983-10-01

    In the late 1960s, Quebec demonstrated its willingness to influence migration by creating a Ministry of Immigration. The goal of the Ministry changed over the course of a decade from assuring harmonious integration of immigrants to obtaining a greater role in recruitment and selection as well as in reception and establishment. In the early 1970s the Canadian government undertook a significant revision of its immigration policies. The most significant change was probably the requirement of an annual estimate of the number of immigrants judged opportune to admit during a particular time period. to be preceded by consultations with the provinces concerning demographic needs and the labor market. A 1978 agreement between Quebec and the Canadian government gave Quebec a greater role in immigrant selection and recruitment, and in effect allowed it to develop its own immigration policy. Ability to absorb potential immigrants became the primary criterion in setting quotas for Quebec. The approach of the federal government has not changed greatly since the new policy came into use. The extent of annual net immigration judged desirable has changed from about 75,000 persons initially to about 55,000 more recently. The federal government has always viewed immigration as a possible solution to labor market problems, but estimates of manpower needs became very volatile in the late 1970s with the general rise in rates of unemployment, and survey results lost importance as a source of guidance. The government estimated that 20 to 25 thousand immigrants selected to fill specific manpower needs could be accomodated annually in the 1980s, but the collapse of the labor market following the economic crisis caused a downward revision in estimates for 1982-83 to 8000 to 10,000 workers with jobs already in hand. In order to participate in planning of immigration, Quebec had to develop a research program desinged to identify its capacity to absorb immigrants each year. The 1st step was to

    1987-01-01

    The Quebec and Ontario health insurance and health service delivery systems, developed within the parameters of federal regulations and national financial subsidies, provide generally universal and comprehensive basic hospital and medical benefits and increasingly provide for the delivery of long-term care services. Within a framework of cooperative federalism, the health care systems of Ontario and Quebec have developed uniquely. In terms of vital statistics, the health of Ontario and Quebec residents generally is comparable. In viewing expenditures, Quebec has a more clearly articulated plan for providing accessible services to low-income persons and for integrating health and social services, although it has faced some difficulties in seeking to achieve the latter goal. Its plans for decentralized services are counter-balanced by a strong provincial role in health policy decision-making. Quebec's political culture also allows the province to play a stronger role in hospital planning and in the regulation of physician income than one finds in Ontario. These political dynamics allow Quebec an advantage in control of costs. In Ontario, in spite of some recent setbacks, physician interests and hospital sector interests play a more active role in health system bargaining and are usually able to influence remuneration and resource allocation decisions more than physician interests and hospital sector interests in Quebec.

    Successful project management depends upon control over costs, quality, and scheduling. Project management is one ofthe key activities in the construction process. Without it the best planned project has an overwhelming chance of failure. Onthe other hand, a faltering project may be saved from disaster if strong construction managing techniques are implemented atthe right time. Designers of construction projects in Gaza Strip frequently do not have the technical, environmental, social,and statistical data to complete the design. Foreign contractors and consultants may not be familiar with the material and humanresources of the country nor have knowledge of the social and local regulations factor affecting the project. Because of these andother reasons projects in Gaza Strip often suffer from delays and cost overruns which may offset some of their intended benefits.The goal of the present research is to investigate and analyze the nature, length, and cost of delays that occurred in construc-tion projects in Gaza Strip. Data for this study was obtained from 35 construction projects in several locations in the GazaStrip. This paper first discusses the circumstances that give rise to delays, the classification of these according to responsibili-ty, and the effects they have on the project cost and schedule. The data are presented, analyzed, and conclusions are drawn.Perhaps the most significant conclusion from the present study is that adequate planning at very early stages of the project isimportant to limiting delays and cost overruns.%成功的项目管理来自于对费用、质量和进度计划的控制.项目管理是施工过程中的关键部分.没有项目管理,即使是经过周密计划的项目也很有可能会失败.反之,在适当的时候运用有效的建设管理技术,可能将一个蹒跚不前的项目挽救过来.加沙地区的建设项目的设计人员常常没有技术上、环境上、社会上和统计上的数据来支持设计,而外

  18. Differences in access to services in rural emergency departments of Quebec and Ontario.

    Full Text Available Rural emergency departments (EDs are important safety nets for the 20% of Canadians who live there. A serious problem in access to health care services in these regions has emerged. However, there are considerable geographic disparities in access to trauma center in Canada. The main objective of this project was to compare access to local 24/7 support services in rural EDs in Quebec and Ontario as well as distances to Levels 1 and 2 trauma centers.Rural EDs were identified through the Canadian Healthcare Association's Guide to Canadian Healthcare Facilities. We selected hospitals with 24/7 ED physician coverage and hospitalization beds that were located in rural communities. There were 26 rural EDs in Quebec and 62 in Ontario meeting these criteria. Data were collected from ministries of health, local health authorities, and ED statistics. Fisher's exact test, the t-test or Wilcoxon-Mann-Whitney test, were performed to compare rural EDs of Quebec and Ontario.All selected EDs of Quebec and Ontario agreed to participate in the study. The number of EDs visits was higher in Quebec than in Ontario (19 322 ± 6 275 vs 13 446 ± 8 056, p = 0.0013. There were no significant differences between Quebec and Ontario's local population and small town population density. Quebec's EDs have better access to advance imaging services such as CT scanner (77% vs 15%, p < .0001 and most the consultant support and ICU (92% vs 31%, p < .0001. Finally, more than 40% of rural EDs in Quebec and Ontario are more than 300 km away from Levels 1 and 2 trauma centers.Considering that Canada has a Universal health care system, the discrepancies between Quebec and Ontario in access to support services are intriguing. A nationwide study is justified to address this issue.

    This paper analyzes the debates surrounding the privatization of health services financing in Quebec. The objective is to clarify policy-making processes with regard to this important issue and, more generally, to provide a realistic understanding of health-related policy processes in Canada. The analysis is based on a large and continuous sample of mass media and National Assembly debates on the question during the four-and-a-half years following the Chaoulli ruling of the Supreme Court of Canada. These data are used to test four hypotheses about relationships among the types of political actors involved, their policy preferences, the rhetoric they use and the anticipated policy effects they assert. The results are applied to a discussion of questions about the factors that influence the effectiveness of political communication.

    This paper presents a relevant approach to predict the indoor radon potential based on the combination of the radiogeochemical data and the indoor radon measurements in the Quebec province territory (Canada). The Quebec ministry of health asked for such a map to identify the radon-prone areas to manage the risk for the population related to indoor radon exposure. Three radiogeochemical criteria including (1) equivalent uranium (eU) concentration from airborne surface gamma-ray surveys, (2) uranium concentration measurements in sediments, (3) bedrock and surficial geology were combined with 3082 basement radon concentration measurements to identify the radon-prone areas. It was shown that it is possible to determine thresholds for the three criteria that implied statistically significant different levels of radon potential using Kruskal-Wallis one way analyses of variance by ranks. The three discretized radiogeochemical datasets were combined into a total predicted radon potential that sampled 98% of the studied area. The combination process was also based on Kruskal-Wallis one way ANOVA. Four statistically significant different predicted radon potential levels were created: low, medium, high and very high. Respectively 10 and 13% of the dwellings exceed the Canadian radon guideline of 200 Bq/m(3) in low and medium predicted radon potentials. These proportions rise up to 22 and 45% respectively for high and very high predicted radon potentials. This predictive map of indoor radon potential based on the radiogeochemical data was validated using a map of confirmed radon exposure in homes based on the basement radon measurements. It was shown that the map of predicted radon potential based on the radiogeochemical data was reliable to identify radon-prone areas even in zones where no indoor radon measurement exists.

    Robert, Julie

    2011-01-01

    This essay seeks to rationalize and explain the evolution of medical rhetoric in Cité libre by looking at trends in the journal's use of tropes of illness and disease. Through a combination of broad content analysis and close readings, it contrasts how individual metaphors create the impression of a sickening nation and the manner in which these metaphors collectively, albeit paradoxically, act as a national allegory of cure for mid-twentieth-century Quebec's social ills in general, and specifically for its pathological inferiority complex. By examining how the journal uses medical metaphors and specifically how the writers employed the trope of the body politic to illustrate Quebec's national failings, the essay demonstrates how Quebec challenges the rhetorical stability of the age-old metaphor as it attempts to solve, but also creates, problems within Quebec's articulation of its own nationhood.

  10. The 'common knowledge' of Quebecers: quantifying the evidence of historians testifying for defendant tobacco companies.

    Science.gov (United States)

    Callard, Cynthia

    2016-09-01

    The 'common knowledge' defence is a legal strategy which has been successfully used by defendant tobacco companies to avoid legal responsibility for the harms caused by smoking. Tobacco companies have hired professional historians to try to persuade courts about a longstanding high level of public awareness regarding the risks of tobacco use. To support this argument, they have used archival news clippings and media reports. Two historians were hired by tobacco companies to offer this defence during a recent class action trial in Canada, following which they were required to submit to the court the collection of media materials which had been gathered by history students to assist their testimony. Included in this collection were tobacco advertisements and other news items about tobacco products which the students had inadvertently also collected. Quantifying this collection reveals that even by the tobacco industry's own construct, the information environment surrounding Quebec smokers in the middle 20th century included more prosmoking messages than information about the risks of smoking.

    Recently, Chalifoux Dairy of Sorel, Quebec, invested, with the help of Hydro-Quebec, in three new technologies to increase the energy efficiency of the production line. A summary of these technological improvements was presented. The three new technologies were induction heating pasteurization, ultraviolet sterilization and ultrafiltration. Ultra-high temperature (UHT) induction heating is now used to pasteurize cream and chocolate milk. This new pasteurization method has reduced product returns from 5 per cent to nil. UHT cream is packaged in small disposable containers that are previously sterilized by a radiant ultraviolet source. An ultrafiltration method also has been implemented for production of specialty cheese at the dairy. This process yields 20 per cent more production with 30 per cent less energy than traditional methods. Hydro-Quebec assisted Chalifoux Dairy with a subsidy of $596,000 for these energy-efficiency modifications.

  13. The Secondary Sex Ratio at Birth Was Depressed in Quebec by the Sovereignty Referendums.

    Science.gov (United States)

    Grech, Victor

    2015-05-01

    Globally, male live births exceed female live births by approximately 3%. The secondary sex ratio is conventionally expressed as male births divided by total live births (M/T). Many factors have been implicated as influencing this ratio, such as stress (including non-violent political events) and toxins, both of which reduce it. The Quebec government twice proposed referendums to its populace advising sovereignty. This study was carried out in order to ascertain whether the referendums had any effect on the M/T ratio in Quebec and in Canada as a whole. Annual births in Quebec and Canada were compared for the index (referendum) years 1980 and 1995 versus the sum of the preceding and following five year periods, for each event. The monthly M/T ratio for Quebec before and after the 1995 referendum was also calculated. This review covered 8 099 600 live births. In Quebec, the M/T ratio was lower in the two referendum years than in the preceding and following five year periods, and was significantly lower after the 1995 referendum (P = 0.04). No significant changes were noted for Canada as a whole. Monthly calculations for Quebec showed a decline in the M/T ratio three months after the 1995 referendum (P = 0.035), followed by a rapid recovery (P = 0.001). The second Quebec referendum on sovereignty in 1995 had a higher voter turnout than the 1980 referendum and was more closely run. Reductions in the M/T ratio have been noted in association with stressful population events, including non-violent political activities. This may have been the case in Quebec, where the M/T ratio declined in association with two referendums that proposed sovereignty, possibly due to the stress engendered by these events and the potential outcomes.

    Full Text Available Twenty-three cases of blastomycosis were reported in a survey conducted in the province of Quebec from 1981–90. Thirteen patients resided south of the St Lawrence River and the other 10, north. Two small geographical clusters were apparent in and around the cities of Sherbrooke and Quebec. The male to female ratio was 1.6:1 and the median age was 47 years (range 26 to 77. Lung involvement was observed in 19 cases and was the only site involved in 11. Cutaneous manifestations were reported in 11 cases while bone infection (three cases and central nervous system (CNS infections were also noted. Diagnosis was confirmed by culture in 21 cases and by histopathology in two cases. Of the 21 culture-positive cases, 12 strains of Blastomyces dermatitidis were isolated from lungs, nine from skin, and one each from bone and brain. Serodiagnostic tests by immunodiffusion or complement fixation were positive for only one of the 10 patients known to have been tested. Ten patients were treated with amphotericin B, 11 with ketoconazole, one with fluconazole and eight underwent surgery. While amphotericin B was used in eight of the 10 earliest treated cases, ketoconazole was administered in 10 of the 13 more recent cases. Of the patients for whom follow-up data have been obtained, 21 are reported cured (one of whom was not treated and one patient died of another cause. This survey confirms that blastomycosis is a rare disease in this endemic area and that patterns of therapy are changing.

The combination process was also based on Kruskal–Wallis one way ANOVA. Four statistically significant different predicted radon potential levels were created: low, medium, high and very high. Respectively 10 and 13% of the dwellings exceed the Canadian radon guideline of 200 Bq/m{sup 3} in low and medium predicted radon potentials. These proportions rise up to 22 and 45% respectively for high and very high predicted radon potentials. This predictive map of indoor radon potential based on the radiogeochemical data was validated using a map of confirmed radon exposure in homes based on the basement radon measurements. It was shown that the map of predicted radon potential based on the radiogeochemical data was reliable to identify radon-prone areas even in zones where no indoor radon measurement exists. - Highlights: • 5 radiogeochemical datasets were used to map the geogenic indoor radon potential. • An indoor radon potential was determined for

  17. Evaluating the SWAT's snow hydrology over a Northern Quebec watershed

    The snowmelt is an important component of the Soil Water Assessment Tool (SWAT[1]) model's hydrology when applied in snowy watersheds where spring flows are dominated by snow melting. However, little is known about its performance in modeling Nordic environments and its accuracy with respect to operational snowmelt models because most studies were conducted in rainfall-runoff catchments. To fill this gap in SWAT's knowledge, we aim to evaluate its performance for simulating a snowy Nordic catchment streamflow with comparison to the Streamflow Synthesis and Reservoir Regulation (SSARR[2]) model. SSARR is one of the selected operational models by the Snow Hydrology Guide as valuable tool for snowmelt runoff simulation (Ontario Ministry of Natural Resources, 1989). In the Côte Nord region of Quebec, most of the streamflow come from snowmelt in watersheds. Understanding the interactions among snow accumulation, snowmelt and streamflow generation is a challenge for water resources management in Quebec, since this province is the Canada's leader in hydroelectric energy production. The selected snow-covered watershed, namely the Outardes Basin, presents extreme climatic conditions. Few examples of model calibration in this Nordic environment exist because of the scarcity of reliable data. The basin has the interest of being well instrumented providing a comprehensive dataset to implement SWAT over this Nordic watershed. The evaluation indicates that SWAT has a good performance in simulating the daily, monthly, seasonal and annual mean discharges with low volume biases over the calibration and validation periods. The predominantly spring snow-melting generated streamflow is simulated with a good accuracy for both its magnitude and its timing. Seasonal snowpack plays an important role in defining the hydrologic regime where the accumulated snowmelt runoff contributes to 64% of the annual runoff. When we compared SWAT's results to SSARR, comparable performances in

    A report on REE concentrations within the estuary of the Great Whale River in northwest Quebec and in Hudson Bay is given, showing concentrations which are less than those predicted by conservative mixing of seawater and river water, indicating removal of REE from solution. REE removal is rapid, occurring primarily at salinities less than 2 percent and ranges from about 70 percent for light REE to no more than 40 percent for heavy REE. At low salinity, Fe removal is essentially complete. The shape of Fe and REE vs. salinity profiles is not consistent with a simple model of destabilization and coagulation of Fe and REE-bearing colloidal material. A linear relationship between the activity of free ion REE(3+) and pH is consistent with a simple ion-exchange model for REE removal. Surface and subsurface samples of Hudson Bay seawater show high REE and La/Yb concentrations relative to average seawater, with the subsurface sample having a Nd concentration of 100 pmol/kg and an epsilon(Nd) of -29.3; characteristics consistent with river inputs of Hudson Bay. This indicates that rivers draining the Canadian Shield are a major source of nonradiogenic Nd and REE to the Atlantic Ocean.

    Full Text Available OBJECTIVE: To estimate the nonhospital costs of treating chickenpox and to ascertain the opinion of parents regarding the usefulness of vaccination. DESIGN: Retrospective postal survey. SETTING: Province of Quebec. PARTICIPANTS: Random sample of 3333 families with children aged six months to 12 years. OUTCOME MEASURES: For cases of chickenpox that occurred between September 1, 1997 and August 31, 1998, the use of health services, time away from school or work, patient care required, direct and indirect costs for the families and the health care system, and the opinion of parents regarding chickenpox and the vaccine were evaluated. RESULTS: The response rate was 64.7%, and 18.8% of households reported a history of chickenpox, a total of 693 cases. A physician was consulted in 45.8% of these cases, and medication was used in 91.7%. The frequency of hospitalizations was 0.6%. Time away from work or school caused by the disease was 4.1 days on average, with 46.5% of absences being attributed to the risk of contagion. The total average cost of a case of chickenpox was $225. Direct expenses for households accounted for 11% of the total cost, public sector direct costs 7%, indirect costs related to absence from work 38% and caregiving time 45%. A majority of parents (70% were in favour of a systematic childhood immunization program. CONCLUSIONS: Chickenpox without complications is disruptive for families, but the direct costs for families and the public sector are relatively small.

    The (87)Sr/(86)Sr isotope ratios were measured on grape, wine and soil samples collected in 13 commercial vineyards located in three major wine producing areas of Quebec (Canada). The soils yield Sr isotope ratios that are intimately related to the local geology and unambiguously discriminate the different producing areas. A strong relationship exists between the (87)Sr/(86)Sr isotope ratios of the wine and the grapes. This suggests that the vinification process does not alter the overall Sr budget. Although the Sr isotope ratios of the grapes do not show a strong correlation with the bulk Sr isotope composition of the soil, they do correlate strongly with the Sr isotope composition contained in the labile fraction of the soil. This indicates that the labile fraction of the soil represents the Sr reservoir available to the plant during its growth. This study demonstrates that the Sr isotope approach can be used as a viable tool in forensic science for investigating the provenance of commercial wines.

    The Brown-Peterson task is used to assess verbal short-term memory as well as divided attention. In its auditory three-consonant version, trigrams are presented to participants who must recall the items in correct order after variable delays, during which an interference task is performed. The present study aimed to establish normative data for this test in the elderly French-Quebec population based on cross-sectional data from a retrospective, multi-center convenience sample. A total of 595 elderly native French-speakers from the province of Quebec performed the Memoria version of the auditory three-consonant Brown-Peterson test. For both series and item-by-item scoring methods, age, education, and, in most cases, recall after a 0-second interval were found to be significantly associated with recall performance after 10-second, 20-second, and 30-second interference intervals. Based on regression model results, equations to calculate Z scores are presented for the 10-second, 20-second and 30-second intervals and for each scoring method to allow estimation of expected performance based on participants' individual characteristics. As an important ceiling effect was observed at the 0-second interval, norms for this interference interval are presented in percentiles.

    Full Text Available Abstract As in most metropolises throughout the world, the influx of migrants has completely altered the look of schools in Quebec’s larger cities. Among the immigrant children recently registered in Quebec schools, a number had not previously received or completed regular schooling. The case of pupils in a delayed schooling situation is still a misunderstood reality: we know little about them, especially their literacy development. However, in Quebec, successful reading acquisition in French as a second language is a sine qua non condition to school achievement and, therefore, represents a major challenge for these learners. It thus seems important to gather data on delayed schooling learners so as to enhance our knowledge of them and of their parents, and better understand home literacy practices and other demolinguistic variables related to success in reading acquisition. The objectives of this exploratory study are to trace a demolinguistic portrait of the parents and the children in such a situation; to present a synthesis of the declared literacy practices of these immigrant pupils; and to complete the portrait by exposing, in an exploratory fashion, the expectations and the perceptions of these parents towards schooling. The study was based on a questionnaire which was completed by 10 parents of pupils in a delayed school situation, and by 72 parents of regular allophone pupils recently registered in the primary or secondary level.

  10. Risk factors associated with West Nile virus mortality in American Crow populations in Southern Quebec.

    2010-01-01

    Soon after the appearance of West Nile virus (WNV) in North America, a number of public health authorities designated the American Crow (Corvus brachyrhynchos) a sentinel for WNV detection. Although preliminary studies have suggested a positive association between American Crow mortality and increased risk of WNV infection in humans, we still know little about dynamic variation in American Crow mortality, both baseline levels and mortality associated with WNV. We hypothesized that the complex social behavior of American Crows, which is shaped by age and seasonal factors, influences both baseline mortality and WNV mortality in American Crow populations. We examined American Crow mortality data from Quebec for the 2005 WNV surveillance year, which lasted from 5 June to 17 September 2005. The variables of interest were age, gender, body condition index, time of year, and land cover. We used a log-linear model to examine baseline mortality. Logistic regression and general linear regression models were constructed to examine variables associated with mortality due to WNV. We found that both age and time of year were key variables in explaining baseline mortality. These two variables were also risk factors for WNV mortality. The probability that a carcass tested positive for WNV increased with the age of the dead bird and as summer progressed. WNV-positive carcasses also had a lower body condition index than WNV-negative carcasses. We believe that the first major wave of American Crow mortality observed in the early summer of 2005 was the result of natural mortality among young American Crows. Because this mortality was not linked to WNV, it appears that American Crow may not be a good species for early detection of WNV activity. Our data also suggest that second-year American Crows play a major role in propagating WNV during their movements to urban land covers during midsummer.

    Since the 1960's, marked sociocultural and economic changes have affected lifestyle, religious practices, and family structure among French Canadians in Quebec. Recent nutritional assessment was unavailable, despite indications of change. A survey was carried out in 1988 in a representative sample living in Greater Montreal, to obtain current data on food habits, nutrient intakes and sociodemographic factors, using interviewer-administered questionnaires and seven-day food records. Some 845 families (1450 individuals from different age groups) were studied in two phases: summer/fall and winter/spring. Mean household size in the study population was 2.7. Among adults, extremes of educational level were observed, with 33% having elementary school only and 28% having completed university. On average, each household spent $CAN 89.90 a week for food, $26.00 for tobacco, and $13.50 for alcohol. Breakfast was eaten regularly by 90% of subjects while 96% ate lunch and 99% ate dinner. Morning snacks were consumed by 36% and afternoon snacks were taken by 50%. Milk was consumed with breakfast by 24% of respondents, with lunch by 19%, and with dinner by 24%. On weekdays, 81% of subjects ate their main meals at home, while on weekends this figure was 95%. Time spent for meals varied by meal, and was slightly longer on weekends. Specialty diets, including vegetarianism, were followed by 7% of the study subjects, while 22% adhered to health-related diets. The food record analyses revealed adequate nutrient intakes overall in relation to the 1990 Canadian Recommended Nutrient Intakes, although further investigation is needed before addressing dietary quality in specific age-sex groups. Protein comprised 16% of energy, fat 38%, and carbohydrates composed 45% or 46% for males and females, respectively. Subsequent analyses will evaluate nutrient intakes in relation to health and sociodemographic indicators in this population.

    Objective Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by an array of organ manifestations that can appear during flares and disappear during remissions. The objectives of this study were: (i) to examine SLE manifestation groups longitudinally in an SLE cohort; and (ii) to assess the association between early antimalarial treatment and renal manifestations. Methods Seven SLE manifestation groups-cutaneous, hematologic, lung, musculoskeletal, neuropsychiatric, serositis, renal-were tracked using Kaplan-Meier survival curves in an incident SLE cohort from Quebec health administrative data ( n = 2010). A subgroup with provincial drug insurance coverage was followed over time to examine the association between early antimalarial treatment (within three months after SLE diagnosis) and renal manifestations using a Cox proportional hazards survival model. Results Cutaneous manifestations was the most common manifestation at SLE diagnosis (30.0%, 95% CI: 27.7-32.2%). About two-thirds (66.2%, 95% CI: 63.4-68.9%) of patients had evidence of at least one SLE manifestation at diagnosis, which increased to 87.2% (95% CI: 84.2-90.3%) by the end of follow-up. After adjusting for age, sex, early concomitant systemic steroid therapy, Charlson comorbidity index, primary care visits in the year prior and other SLE manifestations at baseline, no statistically significant association was established between antimalarial therapy and renal manifestations. Conclusion This study provides insight regarding organ manifestations within a population-based sample. Most patients identified with SLE had other diagnostic evidence that supports an underlying diagnosis of SLE. No protective effects for antimalarial agents against renal manifestations could be established in this population-based cohort.

    This profile presented details of a major retrofit of the Colisee des Bois-Francs Ice Rink in Victoriaville, Quebec. The retrofit included the recovery of heat rejected from the refrigeration system; extensive integration of the refrigeration system with heating, ventilation, and dehumidification systems; short-term heat storage; and the installation of a variable condensing temperature and pressure system. Characteristics of the arena were presented, including details of annual energy consumption, energy costs, and the surface area of the building, which was built in 1978. Annual energy costs for the building were estimated at $90,000. The overall cost of the retrofit was $693,300, with technical support provided by the CANMET Energy Technology Centre. Two factory-built commercial refrigeration systems were installed using floating head pressure. Heat transfer fluid in the cold secondary loop was a mixture of water and methanol, while the warm secondary loop contained a mixture of water and ethylene glycol. Energy efficiency measures included using condensation heat rejected in the warm secondary loop and transferred through a coil in the ventilation duct. A simplified system schematic was presented. Building energy consumption savings were estimated at 14 per cent savings for 50 per cent greater cooling capacity compared with the previous system. The use of modular package refrigeration units confined the refrigerant in the mechanical room and reduced the amount of refrigerant required by 70 per cent. Potential refrigerant leaks were also reduced. With the older system, leaks accounted for 120 t equivalent of carbon dioxide (CO{sub 2}) released per year. Additional benefits of the new system include better quality ice, a more reliable system and greater comfort for spectators. 2 figs.

    Biological carbon sequestration by forest ecosystems plays an important role in the net balance of greenhouse gases, acting as a carbon sink for anthropogenic CO2 emissions. Nevertheless, relatively little is known about the abiotic environmental factors (including climate) that control carbon storage in temperate and boreal forests and consequently, about their potential response to climate changes. From a set of more than 94,000 forest inventory plots and a large set of spatial data on forest attributes interpreted from aerial photographs, we constructed a fine-resolution map (∼375 m) of the current carbon stock in aboveground live biomass in the 435,000 km(2) of managed forests in Quebec, Canada. Our analysis resulted in an area-weighted average aboveground carbon stock for productive forestland of 37.6 Mg ha(-1), which is lower than commonly reported values for similar environment. Models capable of predicting the influence of mean annual temperature, annual precipitation, and soil physical environment on maximum stand-level aboveground carbon stock (MSAC) were developed. These models were then used to project the future MSAC in response to climate change. Our results indicate that the MSAC was significantly related to both mean annual temperature and precipitation, or to the interaction of these variables, and suggest that Quebec's managed forests MSAC may increase by 20% by 2041-2070 in response to climate change. Along with changes in climate, the natural disturbance regime and forest management practices will nevertheless largely drive future carbon stock at the landscape scale. Overall, our results allow accurate accounting of carbon stock in aboveground live tree biomass of Quebec's forests, and provide a better understanding of possible feedbacks between climate change and carbon storage in temperate and boreal forests.

    2015-08-01

    Full Text Available The Quebec Social Forum (QSF took place 23-26 August 2007 in Montreal. It attracted about 5000 people from across Quebec. Both organizers and observers viewed the event as an unqualified success. In this article, we seek to describe and document this historic gathering and to understand it in its Quebec context, against the larger organizing process which produced it. We also situate the Social Forum, both as event and process, within the longer history of social mobilization in Quebec. Historicizing the Social Forum in this way helps us interpret its cleavages and conflicts more adequately and apprehend its larger significance. We argue that the conflicts that have plagued the organizing of the Quebec Social Forum are a reprise of those that appeared in the movement in the late 1990s and came to a head in the 2001 massive demonstrations against the Free Trade Agreement of the Americas in Quebec City. The chasm then was widely perceived as one over tactics but we argue, then and now, it is more substantive than that. It is about the clash of profoundly different ethics, practices and theories of democracy and, beneath them, different horizons of hope and visions of transformation. The organizing of the Social Forum is the occasion for this debate, which may say something about the significance of the Social Forum more generally and the challenge it poses to established cultures and practices of politics on the left. The cleavage is generational but not only or simply. It signals a struggle and transition but the outcomes are not yet clear and are certainly not pre-ordained.

    The author uses census data to analyze 10 variables relating to the distribution of city size in the province of Quebec between 1871 and 1976. Three phases in the development of the urban system are identified: the period from 1871 to 1921, when urban primacy reached a maximum; the transition-maturation period from 1921 to 1956, when lognormality reached a maximum; and the period from 1956 to 1976, when the metropolitanization process resulted in a renewed trend toward urban primacy. The ethno-linguistic dualism existing in Quebec is discussed as a possible factor contributing to the unbalanced nature of the urban structure.

    Full Text Available Longevity runs in families, either through genetic or environmental influences. Using Quebec civil registration and historical Canadiancensuses, we compared the longevity of siblings and spouses of 806 centenarians to a group of controls, all born in Quebec at the turnof the 20th century. Our results show that siblings of centenarians, who share half of their genes and a common childhood environment,lived 3–4 years longer than their birth cohort. However, husbands and wives of centenarians lived 4 and 2.5 years longer than theircounterparts of the same sex, respectively, suggesting that longevity is also modulated by shared environment in adulthood.

    In many Western nations, including England and Wales, Sweden, and the US, there is a current trend towards delayed childbearing because of women's pursuit of a career, later marriage, a longer interval between marriage and the 1st birth, and the increasing number of divorcees having children in a 2nd marriage. Wives of men in social classes I and II in England and Wales are, on average, having their 1st child at 27.9 years, 1.6 years later than in 1973, and in social classes IV and V, 1.0 years later than in 1973, at a mean age of 23.7 years. Consequently, the total period fertility rate for British women aged 30-34 years, 35-39 years, and 40 and over increased by 4%, 2%, and 4%, respectively, between 1982-83, in contrast to reductions of 2% and 3%, respectively, in the 15-19 year and 20-24 year age groups, with the 25-29-year-olds remaining static. The average maternal mortality for all parties in England and Wales during 1976-78 was 106/million for adolescents, 70.4/million for 20-24 year-olds, and 1162/million for those aged 40 years and older. The specific obstetric and allied conditions which increase with age are the hypertensive diseases of pregnancy, hemorrhage, pulmonary embolism, abortion, cardiac disease, caesarean section, ruptured uterus, and amniotic fluid embolism. The Swedish Medical Birth Registry of all live births and perinatal deaths since 1973 has shown that the risk of late fetal death is significantly greater in women aged 30-39 years than in those of the same parity and gravidity aged 20-24 years. The risk of giving birth to low birth weight babies preterm and at term and of premature labor are similarly increased. The early neonatal death rate also was increased for primigravidas and nulliparas in the 30-39 year age group but not in parous women. This is, in part, due to the rise in incidence of fetal abnormalities with advancing maternal age because of chromosomal and nonchromosomal anomalies. These also appear to be the cause of the

    Dispute about adjustment in contract sum caused by price fluctuation during the project delay is gradually increasing. Firstly, the division of responsibility on delay is determined under single event delay and common delay. Secondly, it is proposed that the divide of responsibility on price fluctuation during delay is determined based on the principle of "default not to benefit", and it is pointed out that determine of price indices under delay is different from normal construction progress when applying the formula of adjustment in contract sum. Thirdly, analysis of the determination of price indices under single event delay and common delay respectively based on above principle.%工期延误期间因物价波动引起的价款调整容易引起纠纷。首先,对单事件延误和共同延误这两种情况进行责任划分;其次,提出基于违约者不受益原则对工期延误期间物价波动进行责任划,并指出调价公式中价格指数在工期延误情况下的确定方法与施工进度正常情况下的确定方法有所不同;最后,基于上述原则分别在单事件延误和共同延误两种情况下对价格指数的确定进行详细分析。

  5. The economic impact of wind industry development in Quebec; Les retombees du developpement de l'industrie eolienne au Quebec

    The economic impact of current and future development of wind power in Quebec was discussed. Key events were outlined, beginning with Hydro-Quebec's request for bids in 2003 for 1000 MW of wind power development. More than 4000 MW of power were filed under this call, where 8 projects were selected totalling 990 MW. Both direct and indirect economic impacts were attributed to start-up factories in the Gaspe region and elsewhere across the province. Energy capacity was increased in 2006 by 2,500 MW and is expected to reach more than 4,000 MW by 2015. It was noted that since the government of Quebec chose a non-traditional call for tender to support its emerging industry, it is difficult to attach an exact price tof wind energy, as the bid price included economic development costs associated with regional and provincial requirements. The second part of this document addressed the economic impact of wind industry development from 1997 to 2005, and the anticipated development from 2006 to 2015. Although the economic impact of wind energy development was small for the period 1997-2006, it was important for energy development in the Gaspe region, and established the groundwork for future development and the involvement of local wind tower manufacturers, engineering consulting firms, and the growth of local wind-related businesses in the region. It is anticipated that wind energy development will be very significant in terms of job creation. In addition, Quebec universities are dedicating more resources to training skilled turbine personnel and research in leading-edge fields to improve wind turbine design. It is estimated that $10 million will be paid annually in royalties to municipalities and landowners. In conclusion, from an environmental perspective, it is expected that 4,000 MW of wind capacity will annually produce about 12 TWh of electric energy, and displace an estimated 4 million tonnes of greenhouse gases (GHGs) annually. 17 refs., 16 tabs.

  6. Delay Independent Criterion for Multiple Time-delay Systems

    Chang, C. J.; Liu, K. F. R.; Yeh, K.; Chen, C. W.; Chung, P. Y.

    Based on the fuzzy Lyapunov method, this work addresses the stability conditions for nonlinear systems with multiple time delays to ensure the stability of building structure control systems. The delay independent conditions are derived via the traditional Lyapunov and fuzzy Lyapunov methods for multiple time-delay systems as approximated by the Tagagi-Sugeno (T-S) fuzzy model. The fuzzy Lyapunov function is defined as a fuzzy blending of quadratic Lyapunov functions. A parallel distributed compensation (PDC) scheme is utilized to construct a global fuzzy logic control (FLC) by blending all linear local state feedback controllers in the controller design procedure. Furthermore, the H infinity performance and robustness of the design for modeling errors also need to be considered in the stability conditions.

    In a cohort of some 11,000 men born 1891-1920 and employed in the Quebec chrysotile production industry, including a small asbestos products factory, of 9780 men who survived into 1936, 8009 are known to have died before 1993, 38 probably from mesothelioma--33 in miners and millers and five in factory workers. Among the 5041 miners and millers at Thetford Mines, there had been 4125 deaths from all causes, including 25 (0.61%) from mesothelioma, a rate of 33.7 per 100,000 subject-years; the corresponding figures for the 4031 men at Asbestos were eight out of 3331 (0.24%, or 13.2 per 100,000 subject-years). At the factory in Asbestos, where all 708 employees were potentially exposed to crocidolite and/or amosite, there were 553 deaths, of which five (0.90%) were due to mesothelioma; the rate of 46.2 per 100,000 subject-years was 3.5 times higher than among the local miners and millers. Six of the 33 cases in miners and millers were in men employed from 2 to 5 years and who might have been exposed to asbestos elsewhere; otherwise, the 22 cases at Thetford were in men employed 20 years or more and the five at Asbestos for at least 30 years. The cases at Thetford were more common in miners than in millers, whereas those at. Asbestos were all in millers. Within Thetford Mines, case-referent analyses showed a substantially increased risk associated with years of employment in a circumscribed group of five mines (Area A), but not in a peripherally distributed group of ten mines (Area B); nor was the risk related to years employed at Asbestos, either at the mine and mill or at the factory. There was no indication that risks were affected by the level of dust exposure. A similar pattern in the prevalence of pleural calcification had been observed at Thetford Mines in the 1970s. These geographical differences, both within the Thetford region and between it and Asbestos, suggest that the explanation is mineralogical. Lung tissue analyses showed that the concentration of

    Founder effects are largely responsible for changes in frequency profiles of genetic variants in local populations or isolates. They are often recognized by elevated incidence of certain hereditary disorders as observed in regions of Charlevoix and Saguenay-Lac-Saint-Jean (SLSJ) in Northeastern Quebec. Dominantly transmitted myotonic dystrophy (DM1) is highly prevalent in SLSJ where its carrier rate reaches 1/550, compared with 1/5,000 to 1/50,000 elsewhere. To shed light on the origin of DM1 in this region, we have screened 50 nuclear DM1 families from SLSJ and studied the genetic variation in a 2.05 Mb (2.9 cM) segment spanning the site of the expansion mutation. The markers analyzed included 22 biallelic SNPs and two microsatellites. Among 50 independent DM1 chromosomes, we distinguished ten DM1-associated haplotypes and grouped them into three haplotype families, A, B and C, based on the relevant extent of allele sharing between them. To test whether the data were consistent with a single entry of the mutation into SLSJ, we evaluated the age of the founder effect from the proportion of recombinant haplotypes. Taking the prevalent haplotype A1_21 (58%) as ancestral to all the disease-associated haplotypes in this study, the estimated age of the founder effect was 19 generations, long predating the colonization of Nouvelle-France. In contrast, considering A1_21 as ancestral to the haplotype family A only, yielded the estimated founder age of nine generations, consistent with the settlement of Charlevoix at the turn of 17th century and subsequent colonization of SLSJ. We conclude that it was the carrier of haplotype A (present day carrier rate of 1/730) that was a "driver" of the founder effect, while minor haplotypes B and C, with corresponding carrier rates of 1/3,000 and 1/10,000, respectively, contribute DM1 to the incidence level known in other populations. Other studies confirm that this might be a general scenario in which a major "driver" mutation

    To assess the extent to which new forms of PHC organization - Family medicine groups (FMG) and Network clinics (NC) - established in Quebec since 2003, are associated with a better experience of care than other forms of PHC organization, for patients with chronic diseases. Two surveys were conducted in 2010 in two regions of Quebec: the first among 9,180 residents and the second among 606 PHC organizations. Indices of experience of care were constructed concerning accessibility, continuity, comprehensiveness and perceived outcomes. Five categories of chronic diseases were selected. Descriptive analyses and multilevel regression analyses were conducted to compare the different forms of PHC organization. Individuals with chronic diseases tend to report a better experience of care than those without chronic diseases for all dimensions except for accessibility. FMGs compare to group practices on all dimensions and NCs are associated with a poorer experience of care on most dimensions. Experience of care associated with FMGs and NCs is not superior to that associated with group practices.

  17. Shunning the Bird's Eye View: General Science in the Schools of Ontario and Quebec

    Science.gov (United States)

    Hoffman, Michelle

    2013-04-01

    This paper considers the adoption of general science courses in two Canadian provinces, Ontario and Quebec, during the 1930s. In Ontario, a few science teachers had followed the early general science movements in the United States and Britain with interest. During the 1930s, several developments made the cross-disciplinary, applied thrust of general science particularly appealing to Ontario educationists. These developments included a new demand for vocational education, renewed reservations about pedagogical rationales based on transfer of training, and a growing professional divide between high school science teachers and university scientists. Around the same time, scientists in the Quebec's French-language universities were engaged in a concerted campaign to expand the place of science in the province's francophone secondary schools. The province's prestigious classical colleges, which were the scientists' principal target for reform, privileged an inductive view of science that had little in common with the applied, cross-disciplinary emphasis of the general science courses gaining support in English-speaking school systems. In 1934, however, a popular American general science textbook was adopted in a workers' cooperative devoted to adult education. Comparing the fate of general science within these two education systems draws attention to the fact that general science made inroads in francophone Quebec but had little influence in public and private schools. In light of the growing support general science enjoyed elsewhere, we are led to explore why general science met with little overt interest by Quebec scientists pushing for school science reform during the 1930s.

    1990-08-01

    Hereditary tyrosinemia type I is an autosomal recessive disorder that was recognized in Saguenay-Lac-St-Jean (SLSJ) (Quebec) in 1967. Ninety-eight tyrosinemic children, including some of the 113 children born in the SLSJ region, have been screened by the Quebec Network of Genetic Medicine in the whole province since 1970. The geographical distribution of the 98 children screened showed the majority of them to have been born in the northeastern part of Quebec. The prevalence at birth was estimated at 1/1,846 live borns, and the carrier rate was estimated at 1/20 inhabitants in the SLSJ region. Three control groups matched to the tyrosinemic obligate-carrier couples were generated using the population register of the SLSJ region kept at SOREP. The mean coefficient of inbreeding was only slightly elevated in the tyrosinemic group compared with the control groups and was due to remote consanguinity. The mean kinship coefficient was 2.3 times higher in the tyrosinemic group than in the control groups. In the SLSJ region the places of origin of the tyrosinemic children and their parents did not show a clustered nonuniform distribution. Endogamy was not found to be higher in the tyrosinemic group than in the control groups. All these results support both the hypothesis of a founder effect for tyrosinemia and a high gene frequency in northeastern Quebec.

    2013-12-15

    We present a systematic approach to identify the similarities and differences between a chaotic system with delayed feedback and two mutually delay-coupled systems. We consider the general case in which the coupled systems are either unsynchronized or in a generally synchronized state, in contrast to the mostly studied case of identical synchronization. We construct a new time-series for each of the two coupling schemes, respectively, and present analytic evidence and numerical confirmation that these two constructed time-series are statistically equivalent. From the construction, it then follows that the distribution of time-series segments that are small compared to the overall delay in the system is independent of the value of the delay and of the coupling scheme. By focusing on numerical simulations of delay-coupled chaotic lasers, we present a practical example of our findings.

    Marcil-gratton, N

    1987-04-01

    Currently over 40% of fertile aged couples in Quebec have chosen voluntary sterilization as a fertility control method, and it is estimated that nearly 70% of women will be protected by sterilization before the natural end of their reproductive years. Under these circumstances the probability arises that some proportion will come to regret their decision to seek sterilization. Telephone interviews with 497 randomly selected sterilized women aged 25-44 in the Montreal area in 1985 provided data on their degree of satisfaction with their decisions. The response rate of 67.5% exceeded the expected 60% and the women were similar in characteristics to those of other samples of sterilized women. Some bias may however have been introduced if there were systematic differences in the women not responding. 2 questions were asked to provide estimates of women regretting the sterilization because they would have liked another child. The women were asked if they subsequently regretted their sterilization because they might have wanted another child. Those answering affirmatively were asked if they thought they would actually have attempted pregnancy. A positive answer to the 2nd question was used as the indicator of regret. The results indicated that physicians' estimates of regret are seriously underestimated. 3.9% of the sample said they had discussed the possibility of a reversal with their physicians, but a much higher 21.2% said they had felt regret without openly expressing it to their physician. 12.7% said they would have attempted a later pregnancy and 4.1% said they might have done so. The fundamental variable was age at sterilization. 35.9% of the 167 women aged 20-29 at ligation, 20.5% of the 222 aged 30-34, and 17.9% of the 106 aged 35 or older stated they had at some time regretted their sterilization. 8.4% of those 20-29 at ligation, 8.6% of those 30-34, and 9.4% of those over 35 said they would have tried to have another child. 70% of those who would have wanted

    The Coop Federee addresses all agricultural issues facing rural Quebec. It represents more than 51,000 members from 101 agricultural co-operatives that address a variety of needs on behalf of agricultural producers and consumers. As a wholesaler, the Coop Federee provides goods and services, including petroleum products, to its members in Quebec, Ontario and New Brunswick. This document addressed issues related with the recent announcement by the Quebec Government that Hydro-Quebec would launch a second invitation to bid on 2000 MW wind power. With the first invitation to bid on 1000 MW launched in 2003, the premier of Quebec affirmed to make Quebec a world leader in the field of green energy. The Government of Quebec requires that 60 per cent of the components in the wind park must come from within Quebec. Therefore, if a 100 MW wind park involves an investment of $170 million, then $102 million dollars will undoubtedly be spent in the province, plus any added expenditures such as maintenance, labour and taxes. Over the 20 year lifespan of the project, this represents approximately $3.5 billion dollars from a 2000 MW wind project. This represents a significant contribution to the province's economic development. This paper presented a critical examination of the proposal, with reference to external promoters of wind power. It also addressed the issue of potential negative consequences which may, in the long-term, present a barrier to the development of wind power in the province. 9 refs., 2 tabs., 2 appendices.

    Nearly 2 billion people use groundwater and in Canada it is the potable water supply for about 30% of the population. Groundwater is also used in industrial and agricultural applications, and contributes to important hydrological habitats for various species. Limited research has been conducted to determine the potential impacts of climate change on groundwater. Local studies are crucial to better understand how, for example, increased duration and frequency of storms or drought periods may affect groundwater dependent ecosystems in order to anticipate and mitigate the impacts. Thus, the aim of this research is to explore the effects of climate change on a groundwater-surface water interacting system that supports a fragile ecosystem. This research is used to inform ecological conservation measures. The research site is the 17500 ha Covey Hill Natural Laboratory, which is located on the Quebec, Canada and New York State, USA border in the Chateauguay River watershed. At various locations within the Natural Laboratory there is continuous monitoring of groundwater levels and river flows. Covey Hill is an important recharge zone for the regional aquifer and provides habitat for endangered salamanders in discharge zones. Two hydrogeological models were constructed to represent flow at the site. First, a three-dimensional, finite difference model was developed using MODFLOW software to simulate overall groundwater flow at the research site. Second, a smaller-scale, discrete fracture, transient, three-dimensional, finite difference, integrated model was developed using HydroGeoSphere software to represent in better detail flow from bedrock springs that occur at mid-slope and provide the habitat for endangered salamanders. The models were used to: 1) observe groundwater flow under current climate conditions; 2) quantify water dynamics in response to climate change using 10 scenarios from the Canadian Regional Climate Model (for 1971-2000 and 2041-2070 time periods); and 3

    The impacts of large-scale climate oscillations on hydrological systems and their variability have been documented in different parts of the world. Since hydroclimatic data are known to exhibit non-stationary characteristics, spectral analyses such as wavelet transforms are very useful in extracting time-frequency information from such data. As Canadian studies, particularly those of regions east of the Prairies, using wavelet transform-based methods to draw links between relevant climate indices [e.g., the El Niño Southern Oscillation (ENSO), the North Atlantic Oscillation (NAO), and the Pacific Decadal Oscillation (PDO)] and streamflow variability are not common, this study aims to analyze such relationships for the southern regions of Quebec and Ontario. Monthly and annual streamflow data with a record length of 55 years were used to capture streamflow variability at intra-annual, inter-annual and inter-decadal scales. The continuous wavelet transform spectra of monthly streamflow data revealed consistent significant 6- and 12-month periodicities, which are likely associated with strong seasonality factors. Its annual counterparts showed four different significant periodicities: up to 4 years, 4-6 years, 6-8 years, and greater than 8 years - all of which occurred after the late 1960s/early 1970s. Wavelet coherence analyses show that the influence of ENSO and NAO at the inter-annual scale occurs at 2-6 year periodicities, and the influence of PDO occur at periodicities up to 8 years and exceeding 16 years. Correlations between these climate indices and streamflow were computed to determine the time delay of streamflow response to the influence of ENSO, NAO, and PDO. The lag times ranged from 6-48 months (for monthly data) and 1-4 years (for annual data). This research contributes to our understanding of streamflow variability over the southern parts of Quebec and Ontario, and the role of ENSO, NAO, and PDO phenomena on this variability. These relationships can

    The present study, carried out by the Canadian Wind Energy Association (CanWEA), examines the economic spin-off from development of the wind energy network throughout Quebec and in the Gaspe Peninsula. It covers the classic economic spin-offs, direct, indirect and secondary during the construction (2005-2010) and the operational phases (2011-2015). The further development of this network over the period 2016- 2025 is also discussed. This activity gives rise to thousands of permanent jobs in the two regions during both the construction and the operation phases as well as creating network-related businesses (recruitment, consulting engineering, production, management, financing). Moreover, millions of dollars are paid, and will be paid in future, to municipalities and land owners where the wind turbines are built, or will be built, in the form of fees and rents as well as funds to promote research and specialised training in local universities and research centres.

    Although Quebecers spend more than $10 million per year in hydrocarbon fuels, the production of hydrocarbons in the province is very small. Recently however, companies such as Junex of Quebec and Corridor Resources of Halifax have launched important hydrocarbon exploration programs in the province of Quebec. Quebec has a refining capacity of 500,000 barrels of oil per day and has 3 important refineries and an important petrochemical industry. In addition, the newly launched exploration programs are now beginning to yield results. Other companies have embarked in the exploration trend. These include Gastem, Aquatex, Petrolia, Talisman Energy, Amque and Petrolympia. In September 2006 the Quebec Ministry of Natural Resources issued 383 exploration permits. Since 2006, Junex has produced 1000 barrels of light crude that has been sold to the Ultramar refinery in Saint-Romuald. Junex has also been producing from wells in the Gaspe Peninsula. It was noted however, that successful development of hydrocarbon reservoirs in Quebec will require access to the offshore reserves in the Gulf of St. Lawrence, where a current exploration moratorium is in place. Also, legal boundary definitions will need to be addressed to allow for exploration in the gulf. 3 figs.

    Full Text Available The paper presents practical application of fuzzy sets and system theory in predicting delay, with reasonable accuracy, a wide range of factors pertaining to construction projects. In this paper we shall use fuzzy logic to predict delays on account of Delayed supplies and Labor shortage. It is observed that the project scheduling software use either deterministic method or probabilistic method for computation of schedule durations, delays, lags and other parameters. In other words, these methods use only quantitative inputs leaving-out the qualitative aspects associated with individual activity of work. The qualitative aspect viz., the expertise of the mason or the lack of experience can have a significant impact on the assessed duration. Such qualitative aspects do not find adequate representation in the Project Scheduling software. A realistic project is considered for which a PERT chart has been prepared using showing all the major activities in reasonable detail. This project has been periodically updated until its completion. It is observed that some of the activities are delayed due to extraneous factors resulting in the overall delay of the project. The software has the capability to calculate the overall delay through CPM (Critical Path Method when each of the activity-delays is reported. We shall now demonstrate that by using fuzzy logic, these delays could have been predicted well in advance.

    Full Text Available Q fever, a zoonosis acquired by inhalation of the rickettsia Coxiella burnetii, is rarely diagnosed in Canada. The world incidence has been increasing since 1960, because of progressive dissemination of this microorganism in animal populations, particularly domestic ruminants. Some recent outbreaks were caused by cats. Of 14 cases reported in Quebec between 1989 and the beginning of 1993, nine occurred successively in an 18-month period in the rural region surrounding Trois-Rivières, after contact with livestock or cats. These cases are reported here, with the results of serological screening of the workers of an abattoir where one of the cases worked. Five additional cases reported in Quebec during the same period are briefly reviewed.

    Full Text Available Suicide rates raise with age has remained consistent for more than 150 years but over the last 50 years major changes occurred. We examined Age-Period-Cohort (APC effects on suicide mortality rate by gender in Canada and in Quebec from 1926 to 2008. Durkheim theoretical framework is used to interpret our findings. Descriptive analysis and APC models relating to the Intrinsic Estimator (IE were used to assess these effects. IE model shows suicide net age effect for men in Canada and Quebec as death rate increased until 25 years old before reaching a plateau. For women it’s an inverted "U" shape peaking at mid-adulthood. While period effect differs, a net cohort effect is found for men born in 1941, and women in 1981 until most recent cohorts.

    Full Text Available Abstract Objective To determine the population incidence of juvenile rheumatoid arthritis (JRA in Quebec. Methods We obtained data from Quebec's physician claims database. Incident cases were defined as having a visit for JRA in 2000, no visit in the previous 3 years, a confirmed diagnosis by an arthritis specialist, or having ≥ 2 visits to any physician for JRA, ≥ 2 months apart but within 2 years. Results Cumulative incidence of JRA was 17.8/100,000. Mean age at diagnosis was 9.8 ± 4.6 years, 68% were female and more persons were diagnosed in winter. Subjects had a median of 10 medical visits over the first year. Conclusion Our population based incidence estimate was similar to others. Children and adolescents with JRA are heavy users of medical care. Additional study of environmental or climate- related triggers may be warranted.

    Important modifications to technology assessment, diffusion, adoption, and utilization must take place if the United States is to better employ medical technology and save resources so as to assure access for the uninsured and underinsured. The United States can learn from other health systems that are more successful in achieving these goals. The author selects for comparison the health systems of France and Quebec. The discussion focuses on the differences between the three systems in the management of medical technology on a range of policy-relevant dimensions, including health system structure, attitudes about planning versus market competition, government regulation, the balance between decentralization and centralization, the needs of the individual and those of the society, linkages between technology assessment and policy-making, and the importance of medical technology assessment for medical practice. Seven specific recommendations are made for better managing medical technology in the United States, drawing on what can be observed from the experiences of Quebec and France.

  10. Hydro-Quebec TransEnergie's perspective on overhead transmission line protection against lightning

    2006-07-01

    Hydro-Quebec TransEnergie's interest in transmission line surge arresters (TLSA) was discussed. The utility conducted studies regarding the use of TLSAs to reduce outages caused by lightning in overhead transmission lines having voltages of 52 to 330 kV. It was determined that in some cases, TLSA is the only solution to reducing flashover initiated by lightning. This paper presented the results of 4 different TLSA configurations in which the impact of grounding resistance on TLSA performance was examined in an effort to determine the most effective configuration. The study revealed that lightning flashovers could be reduced by 70 per cent by installing 1 TLSA on every 2 poles of a 52 kV transmission line. The TLSA should be mounted on one pole structure and the earth wire on the unprotected poles should be removed. According to several tests conducted at Hydro-Quebec's Institut de Recherche en Electricite du Quebec (IREQ), the energy absorption capability of arresters from 4 different manufacturers proved to be at least 6 kJ/kv. The arresters failure rate was estimated to 3 per cent every time a lightning strike occurred on a transmission line. It was suggested that a 100 km long line with one pole every 60 meters should not have more than one arrester failure per year. The arresters must be installed with a mechanical device that could disconnect a failed unit from the transmission system to avoid a permanent fault on the network. It was concluded that TLSAs are useful in reducing lightning flashovers caused by lightning. However, Hydro-Quebec TransEnergie still has concerns regarding their cost, reliability, impact on line maintenance, testing difficulties in the field, mechanical stress on the conductors, and their ability to withstand dielectric behaviour under ice. tabs., figs.

    In 1994, public hearings were held in Quebec city concerning a 120 megawatt (MW) gas cogeneration project that was to be coupled with an already existing pulp and paper mill in the downtown area. Cogeneration plants are often described as highly beneficial from the point of view of local environment. It is well known that the burning of natural gas emits far less sulfur dioxide (SO{sub 2}) and particulate matters (PM) than the combustion of oil or coal. The proposed plant would use high pressure vapour from a nearby incinerator plant and natural gas to produce low pressure vapor for the paper mill industry as well as electricity. The cogeneration plant would allow the paper mill to stop burning heavy oil. By using natural gas instead of heavy oil, the new cogeneration-paper mill complex (CPC) is expected to reinforce the recent trend and willingness towards improving downtown air quality. On the other hand, the CPC would emit more CO{sub 2}, due to the production of additional electricity. According to the Rio de Janeiro Agreement ratified in 1988, Canada is committed to stabilize its greenhouse gas emissions by the year 2000. Nevertheless, the cogeneration file is a new option considered by the Quebec Provincial Governement in its last energy triennal plan. However, it must be specified that the Province of Quebec contributes to less than 15 % of the total Canadian CO{sub 2} production although it represents more than 25 % of its population. Furthermore the maximum production of electricity by this file has been set to 250 MW. It is a very small fraction of the total production of electricity in Quebec, which is 200 TW

    Cree births in Quebec are characterized by the highest reported prevalence of macrosomia (~35%) in the world. It is unclear whether Cree births are at greater elevated risk of perinatal and infant mortality than other First Nations relative to non-Aboriginal births in Quebec, and if macrosomia may be related. This was a population-based retrospective birth cohort study using the linked birth-infant death database for singleton births to mothers from Cree (n = 5,340), other First Nations (n = 10,810) and non-Aboriginal (n = 229,960) communities in Quebec, 1996-2010. Community type was ascertained by residential postal code and municipality name. The primary outcomes were perinatal and infant mortality. Macrosomia (birth weight for gestational age >90th percentile) was substantially more frequent in Cree (38.0%) and other First Nations (21.9%) vs non-Aboriginal (9.4%) communities. Comparing Cree and other First Nations vs non-Aboriginal communities, perinatal mortality rates were 1.52 (95% confidence intervals 1.17, 1.98) and 1.34 (1.10, 1.64) times higher, and infant mortality rates 2.27 (1.71, 3.02) and 1.49 (1.16, 1.91) times higher, respectively. The risk elevations in perinatal and infant death in Cree communities attenuated after adjusting for maternal characteristics (age, education, marital status, parity), but became greater after further adjustment for birth weight (small, appropriate, or large for gestational age). Cree communities had greater risk elevations in perinatal and infant mortality than other First Nations relative to non-Aboriginal communities in Quebec. High prevalence of macrosomia did not explain the elevated risk of perinatal and infant mortality in Cree communities.

    To transculturally adapt the Quebec Back Pain Disability Scale for Hindi-speaking population and examine its psychometric properties in patients with low back pain. The Quebec Back Pain Disability Scale was translated and cross-culturally adapted into Hindi following international guidelines. Hindi version of the scale was completed by 120 patients with low back pain and 60 healthy controls. Patients with low back pain were also administered the Hindi-Roland Morris Disability Questionnaire and Visual Analog Scale. Psychometric evaluation included test-retest reliability, convergent and discriminative validity. Exploratory factor analysis was carried out to determine the factor structure. The factorial analysis revealed a four-factor solution (bending/carrying, ambulation/reach, prolonged postures and rest). Convergent validity was confirmed by high correlation of Hindi Quebec Back Pain Disability Scale to the Hindi version of Roland Morris Disability Questionnaire (r = 0.77 and p Disability Scale has good test-retest reliability, discriminative and convergent validity and is appropriate for clinical and research use in Hindi-speaking low back pain patients. Implications for rehabilitation Linguistically and culturally adapted questionnaires help researchers make adequate inferences about instruments measuring health and quality of life. The translated version would serve as a valid research tool allowing comparability of data across cultures thus, providing opportunities for large multicenter, multicountry trials. A Hindi Quebec Back Pain Disability Scale version will help to improve the quality and efficacy of assessment of low back pain by developing in patients, a better understanding of the items which can be easily correlated with the activities of daily living.

    Hydraulic resources currently account for more than 95 per cent of Hydro-Quebec's generation capacity. Hydro-Quebec also plans to purchase more wind power in the future. However, the utility wind and hydroelectric resources will be affected by climatic change in the future. This paper outlined research needed by hydroelectric and water resource managers in order to accurately determine the impacts of climatic change. Parameters included changes in annual and seasonal distribution as well as changes in the variability of natural inflows. The research will be used to determine the configuration of new projects as well as the refurbishment and replacement of existing infrastructure. Load profiles for the future indicate that electricity use will change, with less heating needed in winter, and more air conditioning required in summer months. The Delta method was used to determine impacts of future inflows and hydrological regimes. A case study of climate change impacts and management strategies for the Outardes River system up to the year 2050 was presented. The study showed that higher inflows are expected to produce more energy. Maintenance planning and flood control techniques were also discussed. The study showed that the effects of climate change on each of Hydro-Quebec's systems is expected to follow a similar pattern to the Outardes system. tabs., figs.

  1. Focal mechanisms and variations in tectonic stress fields in eastern Canada (western Quebec and southern Ontario)

    Science.gov (United States)

    Asgharzadeh Sadegh, Parisa

    Earthquakes in western Quebec and southern Ontario present a major contribution to the natural hazards in south eastern Canada due to their proximity to major population centres. However, the seismic characteristics of the events in these regions have not been well documented. Improved knowledge of earthquake distribution and seismic controlling mechanisms provides a great benefit for earthquake hazard analysis in eastern Canada. The available information about the tectonic stress indicators, including focal mechanisms, was compiled for Canada prior to 1994. The present research is concentrated mainly on determination of the focal mechanisms and hypocentre locations of the earthquakes after 1993 with M > 3.5 to characterize the present-day regional and local stress fields in southern Ontario and western Quebec. An attempt was also made to differentiate local zones with comparatively homogeneous tectonic stresses orientation and seismic regimes, thus providing information for future re-assessment of the seismic hazard in each region. Considering seismic parameters such as the trend of the epicentres, focal depths and the state of stress of the events along with their tectonic settings, ten distinct clusters have been proposed for western Quebec and two clusters of events were determined for southern Ontario with comparatively consistent focal mechanisms. The locations and characteristics of seismicity clusters appear to be consistent with the hypothesis that they are near the locations of large historic and prehistoric events, and represent exceptionally persistent aftershocks of past large earthquakes.

    OBJECTIVES: We sought evidence to support the hypothesis that advancing maternal age is potentially causing a rise in preterm birth (PTB) rates in high-income countries. METHODS: We assessed maternal age-specific trends in PTB using all singleton live births in Denmark (n = 1 674 308) and Quebec (n...... = 2 291 253) from 1981 to 2008. We decomposed the country-specific contributions of age-specific PTB rates and maternal age distribution to overall PTB rates over time. RESULTS: PTB rates increased from 4.4% to 5.0% in Denmark and from 5.1% to 6.0% in Quebec. Rates increased the most in women aged 20...... to 29 years, whereas rates decreased or remained stable in women aged 35 years and older. The overall increase over time was driven by age-specific PTB rates, although the contribution of younger women was countered by fewer births at this age in both Denmark and Quebec. CONCLUSIONS: PTB rates increased...

  5. Implications of climate change for downhill skiing in Quebec. Repercussions d'un changement climatique sur l'industrie du ski alpin au Quebec

    Energy Technology Data Exchange (ETDEWEB)

    1988-01-01

    The main objective of this research was to evaluate the sensitivity of downhill skiing to eventual climatic change expected due to increasing levels of atmospheric CO/sub 2/ and other greenhouse gases. The first phase of the study consisted of identifying meteorological criteria relevant to the definition of skiable days. These criteria were subsequently applied to current climatic conditions; they were also applied to projected scenarios of climatic change in order to gauge the impacts of a warmer climate on the alpine ski industry. Preliminary socio-economic impact assessments were then made. Results show a decrease in the number of skiable days of 50% to 70% for southern Quebec; ski resorts equipped with snow-making devices would likely experience a smaller reduction in the number of skiable days ranging from 40% to 50%. Ski resorts in Eastern townships and the Laurentians would be unlikely to operate during the Christmas holidays without significant snow-making facilities. Considering that a day of skiing brings approximately $34 (1981) per person into the Quebec economy, a major revenue loss would result. 3 figs., 3 tabs.

    A municipal waste incinerator near Lower Town Quebec has been identified as a major source of air pollution, notably emissions of dioxins, furans, nitrogen oxides (NOx), volatile organic matter (VOC) and polycyclic aromatic hydrocarbons (PAH). Combustion fumes contain gases such as carbon monoxide (CO), carbon dioxide (CO{sub 2}) and sulphur dioxide (SO{sub 2}), as well as dusts, fly ash and particulate matter that is easily airborne. The risks associated with poor air quality have been evaluated along with the effects of pollutants on young children, pregnant women, senior citizens and those with cardiac problems. Some studies have reported that exposure to NOx may cause lung cancer and certain VOCs can irritate the respiratory tract system. Air quality tests have also revealed the presence of mercury. In combination, all these pollutants create smog. The concrete actions that have been taken to address smog issues were discussed. The distance between the incinerator and different residential areas within Lower Town Quebec have been measured along with air quality. Health risks were found to be higher in areas closer to the incinerator. Major modifications have been recommended in order to reduce pollution emissions from the incinerator. These include modernizing the equipment, installing proper scrubbers, and to ultimately the close the incinerator if it continues to underperform. refs., tabs., figs.

    This paper discussed the proposed construction of a 315 kV power transmission line from the Chenier substation near Mirabel, Quebec to the Outaouais substation in Ange Gardien, Quebec. The 114 km long line will cross 14 municipalities, mostly across private properties. Three quarters of the line will cross agricultural land and the remainder will be through wooded areas. The proposed project requires 2 circuits and 6 conducting wires supported by metal pylons. Both the Chenier and Outaouais substations will require modifications to transformers, circuit switchgear and regulators. The infrastructure is expected to have a service life of 60 years. Quebec's environmental public hearing board, the Bureau d'audiences publiques sur l'environnement (BAPE) examined the sustainability of the project with respect to environmental aspects, economic development, and public safety. The BAPE held public hearings in Montebello, Quebec to hear citizen's views regarding the project. Participants expressed concerns regarding noise, impact on wildlife, aesthetics and the health hazards of electromagnetic fields. It was concluded that the proposed line is necessary. The power failure following the ice storm in 1998 indicated that the region needs a more stable and reliable supply of electricity. This proposed project is within the objectives of Quebec's new energy strategy and will allow a higher volume of electricity exchange between Quebec and Ontario. refs., tabs., figs.

    Delay consideration has been a majorissue in design and test of high performance digital circuits. Theassumption of input signal change occurring only when all internal nodesare stable restricts the increase of clock frequency. It is no longertrue for wave pipelining circuits. However, previous logical delaymodels are based on the assumption. In addition, the stable time of arobust delay test generally depends on the longest sensitizable pathdelay. Thus, a new delay model is desirable. This paper explores thenecessity first. Then, Boolean process to analytically describe thelogical and timing behavior of a digital circuit is reviewed. Theconcept of sensitization is redefined precisely in this paper. Based onthe new concept of sensitization, an analytical delay model isintroduced. As a result, many untestable delay faults under thelogical delay model can be tested if the output waveforms can be sampledat more time points. The longest sensitizable path length is computedfor circuit design and delay test.

A transdisciplinary approach is essential for dealing with complex ill-defined problems concerning human–environment interactions (for example, climate change, for allowing joint research, collective leadership, complex collaborations, and significant exchanges among scientists, decision makers, and knowledge users. Such an approach is widely supported in theory but has proved to be extremely difficult to implement in practice, and those who attempt it have met with heavy resistance, succeeding when they find the occasional opportunity within institutional or social contexts. In this paper we narrate the ongoing struggle involved in tackling the negative effects of climate change in multi-actor contexts at local and regional levels, a struggle that began in a quiet way in 1998. The paper will describe how public health adaptation research is supporting transdisciplinary action and implementation while also preparing for the future, and how this interaction to tackle a life-world problem (adaptation of the Quebec public health sector to climate change in multi-actors contexts has progressively been

    Feurtey, Evariste

    In this research, we built a conceptual model of a sustainable and acceptable wind power policy that we tried to validate through the case study of France and Quebec in the wind energy sector. Our qualitative and comparative approach helps us to illustrate the interaction of institutional variables studied, including the national context of emergence, the balance of power between pressure groups, the supranational and exogenous influences, level of political commitment, policy and regulatory instruments, social acceptance and energy policy mechanisms. The research confirms that the neo-corporatism is present in France as in Quebec. With the unfavorable energy context (low cost of electricity tariff, lack of electricity demand, and an already low zero carbon electric mix), it is an important factor explaining : 1) the 20 years delay accumulated by France and Quebec in the development of wind projects or industrial sector; 2) the 10% limited penetration scale given to wind energy. We also demonstrate that the political commitment to develop wind energy fluctuates with the government majority, the energy context or the influence of pressure groups. This manifests itself in a lack of continuity of policies and tariff instruments used. In both national case studies, the results also show that balanced policies and regulations ensure sustainable development of wind energy only if they allow a sufficient market size. The search results also illustrates that the conceptual division made between acceptance of wind sector, acceptance of ownership, local acceptance is very instructive. Social controversies, though multifactorial, are connected to both a critique of the development model too industrial and private, territorial dilemmas (closed environment), energy context (electric surplus in Quebec), or related to strategic planning system and centralized decision. An important issue for a more acceptable wind policy in the future will come to a greater plurality of ownership

    In most instances, delayed emergence from anesthesia is attributed to residual anesthetic or analgesic medications. However, delayed emergence can be secondary to unusual causes and present diagnostic dilemmas. Data from clinical studies is scarce and most available published material is comprised of case reports. In this review, we summarize and discuss less common and difficult to diagnose reasons for delayed emergence and present cases from our own experience or reference published case reports/case series. The goal is to draw attention to less common reasons for delayed emergence, identify patient populations that are potentially at risk and to help anesthesiologists identifying a possible cause why their patient is slow to wake up.

    We consider application of time-delayed feedback with infinite recursion for control of anharmonic (nonlinear) oscillators subject to noise. In contrast to the case of a single delay feedback, recursive delay feedback exhibits resonances between feedback and nonlinear harmonics, leading to a resonantly strong or weak oscillation coherence even for a small anharmonicity. Remarkably, these small-anharmonicity induced resonances can be stronger than the harmonic ones. Analytical results are confirmed numerically for van der Pol and van der Pol-Duffing oscillators. -- Highlights: → We construct general theory of noisy limit-cycle oscillators with linear feedback. → We focus on coherence and 'reliability' of oscillators. → For recursive delay feedback control the theory shows importance of anharmonicity. → Anharmonic resonances are studied both numerically and analytically.

    End-to-end delay is one of the most important characteristics of Internet end-to-end packet dynamics, which can be applied to quality of services (QoS) management, service level agreement (SLA) management, congestion control algorithm development, etc. Nonstationarity and nonlinearity are found by the analysis of various delay series measured from different links. The fact that different types of links have different degree of Self-Similarity is also obtained. By constructing appropriate network architecture and neural functions, functional networks can be used to model the Internet end-to-end nonlinear delay time series. Furthermore, by using adaptive parameter studying algorithm, the nonstationarity can also be well modeled. The numerical results show that the provided functional network architecture and adaptive algorithm can precisely characterize the Internet end-to-end delay dynamics.

    Full Text Available Dynamical behavior of a class of Cohen-Grossberg models with multiple time-varying delays is studied in detail. Sufficient delay-dependent criteria to ensure local and global asymptotic stabilities of the equilibrium of this network are derived by constructing suitable Lyapunov functionals. The obtained conditions are shown to be less conservative and restrictive than those reported in the known literature. Some numerical examples are included to demonstrate our results.

    We investigated the association between junk food consumption at lunchtime (JCL) and fast-food outlet access near school among secondary-school children in Quebec. A geographic information system database was used to characterize the food environment around a sub-sample of 374 public schools in which 26 655 students were enrolled. The outcome variable was JCL during the previous week, dichotomized into low JCL (none or once) v. high JCL (twice or more). Access to fast-food outlets near school was assessed using an existing database of fast-food outlets in Quebec. Covariates included student (age, sex and self-rated perceived health), family (familial status and parental education) and school (urban/rural status and deprivation) variables. Hierarchical logistic regression models were employed for analyses using PROC GLIMMIX of SAS version 9.3. Province of Quebec, Canada. We used data from the Quebec Health Survey of High School Students (QHSHSS) 2010-11, a survey of secondary-school Quebec students. Exposure to two or more fast-food outlets within a radius of 750 m around schools was associated with a higher likelihood of excess JCL (OR=1·50; 95 % CI 1·28, 1·75), controlling for the characteristics of the students, their families and their schools. The food environment surrounding schools can constitute a target for interventions to improve food choices among secondary-school children living in the province of Quebec. Transforming environments around schools to promote healthy eating includes modifying zoning regulations that restrict access to fast-food outlets around schools.

    The robust H∞ control problem of norm bounded uncertain discrete Takagi-Sugeno (T-S) fuzzy tems with state delay is addressed. First, by constructing an appropriate basis-dependent Lyapunov-Krasovskii function, a new delay-dependent sufficient condition on robust H∞-disturbance attenuation is presented, in which both robust stability and prescribed H∞ performance are guaranteed to be achieved. Then based on the condition, a delay-dependent robust H∞ controller design scheme is developed in term of a convex algorithm. Finally, examples are given to illustrate the effectiveness of the proposed method.

    Three unrecognized field isolates of Infectious Bronchitis Virus (IBV) were recovered from commercial broiler chickens vaccinated with live Mass viral strain (H120). These isolates were identified by immunofluorescence using monoclonal antibodies produced against reference serotypes: Mass, Conn, and Ark. RT-PCRs were performed on viral RNAs to amplify S1 gene using a specific set of primers S1OLIGO3' and S1OLIGO5'. Restriction polymorphism (RFLP) of PCR products was determined by the use of HaeIII restriction enzyme. As expected, patterns of PCR products were different from common pattern of strains assigned to Mass serotype M41, Beaudette, H120, and Florida. Molecular analysis showed a nucleotide insertion in hypervariable region one (HVR-1) of S1 gene of only Quebec isolates (Qu16, Qu_mv and Q_37zm). However, New Brunswick IBV isolate (NB_cp) did not display these insertions. Major amino acid changes involved insertion of two stretches (aa118-119: Arg-Ser and aa141-145: Sys-Ser-Asn-Ala-Ser-Cys) located at N-terrminal and C-terminal regions of HVR-2. It is speculated that cysteine residue located upstream and downstream of Cys-Ser-Asn-Ala-Ser-Cys segment might be involved in the formation of loop structure and disulfide bond that could trigger important epitope changes. Insertion of new NXT and NXS (X not equal to P) glycosylation motifs scattered along S1 region and insertion of cysteine residues in HVR are contributing to the antigenic shifting of Quebec isolates. Fragment insertions were thought to be induced by inter-serotype recombination between vaccine strain (H120) that belongs to Mass serotype and another strain belonging to Ark serotype. Phylogenetic tree based on amino acid sequences showed that Quebec isolates formed a new phylogenetic cluster.

    Balsam poplar seeds are short-lived and require moist seedbeds soon after they are released to germinate. In addition to sexual reproduction, balsam poplar stands can regenerate clonally by root suckering. The origin of stands will in turn affect their genetic structure and root system architecture, which are poorly understood for upland forest stands. Three stands were hydraulically excavated in Quebec (moist) and Alberta (dry) to determine the origin of trees and to characterize root systems with respect to presence of parental roots and root grafts connections. Clones were identified using single-nucleotide polymorphism (SNPs), and all stems, roots and root grafts were aged using dendrochronology techniques. All 82 excavated trees were of sucker origin, and four of the six stands contained a single clone. Parental root connections were found between 22% and 25% of excavated trees, and 53% and 48% of trees were linked with a root graft between the same or different clones, in Alberta and Quebec, respectively. Mean distance between trees connected by parental root was significantly lower than the distance between unconnected trees (0.47 ± 0.25 m vs. 3.14 ± 0.15 m and 1.55 ± 0.27 m vs. 4.25 ± 0.13 m) in Alberta and in Quebec, respectively. The excavations also revealed many dead stumps with live roots, maintained through root connections with live trees. This research highlights that balsam poplar growing in upland stands is a clonal species that can maintain relatively high genotypic diversity, with frequent root connections between trees at maturity. Maintaining an extensive root system through root connections increases the chances of a clone surviving when the above ground tree is dead and may also enhance the resilience of balsam poplar stands after disturbance.

    2004-01-01

    Full Text Available Colorectal cancer is a leading cause of death and the third most common cancer in Canada. Evidence suggests that screening can reduce mortality rates and the cost effectiveness of a program compares favourably with initiatives for breast and cervical cancer. The objectives of the Association des gastro-entérologues du Québec Task Force were to determine the need for a policy on screening for colorectal cancer in Quebec, to evaluate the testing methods available and to propose one or more of these alternatives as part of a formal screening program, if indicated. Fecal occult blood testing (FOBT, endoscopy (including sigmoidoscopy and colonoscopy, barium enema and virtual colonoscopy were considered. Although most clinical efficacy data are available for FOBT and sigmoidoscopy, there are limitations to programs based on these strategies. FOBT has a high false positive rate and a low detection yield, and even a combination of these strategies will miss 24% of cancers. Colonoscopy is the best strategy to both detect and remove polyps and to diagnose colorectal cancer, with double contrast barium enema also being a sensitive detection method. The Task Force recommended the establishment, in Quebec, of a screening program with five- to 10-yearly double contrast barium enema or 10-yearly colonoscopy for individuals aged 50 years or older at low risk. The program should include outcome monitoring, public and professional education to increase awareness and promote compliance, and central coordination with other provincial programs. The program should be evaluated; specific billing codes for screening for colorectal cancer would help facilitate this. Formal feasibility, effectiveness and cost-effectiveness studies in Quebec are now warranted.

  2. Genomic characterization of a large outbreak of Legionella pneumophila serogroup 1 strains in Quebec City, 2012.

    Simon Lévesque

    Full Text Available During the summer of 2012, a major Legionella pneumophila serogroup 1 outbreak occurred in Quebec City, Canada, which caused 182 declared cases of Legionnaire's disease and included 13 fatalities. Legionella pneumophila serogroup 1 isolates from 23 patients as well as from 32 cooling towers located in the vicinity of the outbreak were recovered for analysis. In addition, 6 isolates from the 1996 Quebec City outbreak and 4 isolates from patients unrelated to both outbreaks were added to allow comparison. We characterized the isolates using pulsed-field gel electrophoresis, sequence-based typing, and whole genome sequencing. The comparison of patients-isolated strains to cooling tower isolates allowed the identification of the tower that was the source of the outbreak. Legionella pneumophila strain Quebec 2012 was identified as a ST-62 by sequence-based typing methodology. Two new Legionellaceae plasmids were found only in the epidemic strain. The LVH type IV secretion system was found in the 2012 outbreak isolates but not in the ones from the 1996 outbreak and only in half of the contemporary human isolates. The epidemic strains replicated more efficiently and were more cytotoxic to human macrophages than the environmental strains tested. At least four Icm/Dot effectors in the epidemic strains were absent in the environmental strains suggesting that some effectors could impact the intracellular replication in human macrophages. Sequence-based typing and pulsed-field gel electrophoresis combined with whole genome sequencing allowed the identification and the analysis of the causative strain including its likely environmental source.

    Cannabis cultivation has become increasingly localized, whether soil-based or hydroponic growing methods are used. Characteristics of a given location, such as its climate and the equipment it requires may influence general accessibility or attract different types of offenders based on potential profits. The location of crops, especially hydroponic crops, suggests a certain proximity to the consumer market via semi-urban and urban environments, while making it possible to avoid detection. This article examines the cannabis market through its cultivation. The stability of temporal and spatial clusters of cannabis cultivation, hotspots, and coldspots between 2001 and 2009 in the province of Quebec, Canada, are addressed. Studying the geography of crime is not a new endeavor, but coldspots are rarely documented in drug market research. Using arrests and general population data, as well as Kulldorff's scan statistics, results show that the temporal distribution of cannabis cultivation is highly seasonal for soil-based methods. Hydroponic production shows adaptation to its soil-based counterpart. Stable patterns are found for both spatial distributions. Hotspots for soil-based cultivation are found near several urban centers and the Ontario border. For hydroponic cannabis cultivation, a new hotspot suggests the emergence of an American demand for Quebec-grown cannabis between 2007 and 2009. Curiously, the region surrounding Montreal, the largest urban center in Quebec, is a recurrent and stable coldspot for both methods of cultivation. For all periods, spatial clusters are stronger for soil-based methods than in the hydroponic context. Temporal differences and spatial similarities between soil-based cultivation and hydroponic cultivation are discussed. The role of the metropolis is also addressed. Copyright © 2015 Elsevier B.V.

    This paper establishes two theorems for two time-delayed (chaotic) discrete systems to achieve time-delayed generalized synchronization (TDGS). These two theorems uncover the general forms of two TDGS systems via a prescribed transformation. As examples, we convert the Lorenz three-dimensional chaotic map to an equal time-delayed system as the driving system, and construct the TDGS driven systems according to the Theorems 1 and 2. Numerical simulations demonstrate the effectiveness of the proposed theorems.

    Recent years have witnessed important public investments in physicians' compensation across Canada. The current paper uses data from Quebec to assess the impact of those investments on the volumes of services provided to the population. While total physician compensation costs, average physician compensation and average unit cost per service all rose extremely fast, the total number of services, number of services per capita and average number of services per physician either stagnated or declined. This pattern is compatible with the economic target income hypothesis and raises important policy questions. PMID:24359715

    Current trends suggest a movement towards driving forward a global health research agenda in Canada in order to redress global health research inequalities. In this paper, we explore how to promote the participation of students and new researchers in global health in Quebec. To accomplish this, we undertook a study in order to: 1) document the state of teaching and research activities in global health in Quebec and 2) obtain the point of view of various actors on conducting global health research in the Quebec context. Quantitative and qualitative data were collected through specialized grids and a documentation review (5 major universities), surveys (n=25), individual interviews (n=9), and two convened workshops (n=79). We identified 27 courses with global health content, 36 researchers in Quebec working primarily on global health issues, and 76 global health research projects implemented over the past 5 years. A number of threats and opportunities were reported with regards to engaging in global health research activities, as were a number of strengths and weaknesses with respect to the teaching and research environments in Quebec. There appears to be a relatively strong and growing presence of global health in Quebec universities--although the situation varies across institutions--with room for expansion. This trend is partly attributed to an increase in federal funding for and a growing awareness and profile of global health research activities since 2001 and to a growing expertise in global health research in the province. Students and new researchers, however, continue to face multiple challenges requiring special attention and targeted investment. We conclude with a set of recommendations for key stakeholders.

A transdisciplinary approach is essential for dealing with complex ill-defined problems concerning human-environment interactions (for example, climate change), for allowing joint research, collective leadership, complex collaborations, and significant exchanges among scientists, decision makers, and knowledge users. Such an approach is widely supported in theory but has proved to be extremely difficult to implement in practice, and those who attempt it have met with heavy resistance, succeeding when they find the occasional opportunity within institutional or social contexts. In this paper we narrate the ongoing struggle involved in tackling the negative effects of climate change in multi-actor contexts at local and regional levels, a struggle that began in a quiet way in 1998. The paper will describe how public health adaptation research is supporting transdisciplinary action and implementation while also preparing for the future, and how this interaction to tackle a life-world problem (adaptation of the Quebec public health sector to climate change) in multi-actors contexts has progressively been established during the last 13 years. The first of the two sections introduces the social context of a Quebec undergoing climate changes. Current climatic conditions and expected changes will be described, and attendant health risks for the Quebec population. The second section addresses the scientific, institutional and normative dimensions of the problem. It corresponds to a "public health narrative" presented in three phases: (1) problem identification (1998-2002) beginning in northern Quebec; (2) problem investigation (2002-2006) in which

  10. Delay-Dependent Exponential Stability for Discrete-Time BAM Neural Networks with Time-Varying Delays

    Full Text Available This paper considers the delay-dependent exponential stability for discrete-time BAM neural networks with time-varying delays. By constructing the new Lyapunov functional, the improved delay-dependent exponential stability criterion is derived in terms of linear matrix inequality (LMI. Moreover, in order to reduce the conservativeness, some slack matrices are introduced in this paper. Two numerical examples are presented to show the effectiveness and less conservativeness of the proposed method.

    This paper presents an equivalent-input-disturbance (EID-) based disturbance rejection method for fractional-order time-delay systems. First, a modified state observer is applied to reconstruct the state of the fractional-order time-delay plant. Then, a disturbance estimator is designed to actively compensate for the disturbances. Under such a construction of the system, by constructing a novel monochromatic Lyapunov function and using direct Lyapunov approach, the stability analysis and cont...

    Full Text Available Background: Fragmentation and lack of coordination often occur among organisations offering treatment for individuals with substance-use disorders. Better integration from a system perspective within a network of organisations offering substance-use disorder services can be developed using various integration strategies at the administrative and clinical levels. This study aims to identify integration strategies implemented in Quebec substance-use disorder networks and to assess their strengths and limitations. Methods: A total of 105 stakeholders representing two regions and four local substance-use disorder networks participated in focus groups or individual interviews. Thematic qualitative and descriptive quantitative analyses were conducted. Results: Six types of service integration strategies have been implemented to varying degrees in substance-use disorder networks. They are: 1 coordination activities-governance, 2 primary-care consolidation models, 3 information and monitoring management tools, 4 service coordination strategies, 5 clinical evaluation tools and 6 training activities. Conclusion: Important investments have been made in Quebec for the training and assessment of individuals with substance-use disorders, particularly in terms of support for emergency room liaison teams and the introduction of standardised clinical evaluation tools. However, the development of integration strategies was insufficient to ensure the implementation of successful networks. Planning, consolidation of primary care for substance-use disorders and systematic implementation of various clinical and administrative integration strategies are needed in order to ensure a better continuum of care for individuals with substance-use disorders.

    Engineered NanoMaterials (NM) offer an opportunity to develop a wide variety of new products with unique properties but many studies have shown potential OHS risks specific to NM. Addressing these risks requires knowledge about release of NM into the workplaces. This research aimed to map the state of nanotechnology OHS practices in Quebec through a questionnaire following a first contact by telephone when possible and by compiling the type and volumes of NM used as well as gathering information related to the working conditions and OHS aspects. This survey was conducted among 1310 Quebec industries and 653 researchers working in different specialties potentially involved in the development/production/distribution/integration of NM and use of NM containing products. Overall, 90 questionnaires, including 51 from the industries, were completed. These showed that NM are mainly used into the powder form, in many different sectors and deserve a wide range of markets. The prevention measures implemented vary widely from a workplace to another but about one third of the participants report that they have implemented NP adapted prevention measures but they remain worried on some specific operations. More than 50% of the participants request more information about the safe laboratory/plant design, toxicity, regulation, good work practices and prevention measures, efficiency of personal protective equipment and environmental impacts.

    2016-07-01

    Objective Recent literature shows growing interest in the values displayed by occupational therapists. Yet, none of these writings has so far examined the factors that contribute to the development of occupational therapists' professional values. These factors are important, since values play a pivotal role in forging professional identity, which in the case of some occupational therapists remains somewhat ambiguous. This article proposes possible answers to the following question: What do Quebec Francophone occupational therapists perceive as the building blocks of their professional values? Methods Using a phenomenological qualitative method, the subjective experience of occupational therapists in Quebec, Canada was examined. Twenty-six occupational therapists took part in the study. Results As intended, their professional experience was varied. According to the participants, four factors contributed significantly to their professional values: professional experience, university training, personal experience, and professional development. However, fewer than 50% of the participants cited six other factors (workplace, family upbringing, personal development, personality and abilities, professional normative framework, and sociocultural background). Conclusions Most of these results are consistent with those documented in existing works. They point to the relevance of discussing professional values during university training and continuing professional development, as well as encouraging occupational therapists to become exemplars for their colleagues and interns. This study constitutes an initial step in understanding how occupational therapists' axiological identity is formed.

    Full Text Available Objectives. The objectives of this study were to examine the spatial accessibility to alcohol outlets in Quebec and to assess the association between neighborhood level characteristics and availability of alcohol outlets. Methods. The Tobit Model was used to assess the association between neighborhood level characteristics and the availability of alcohol outlets within 500, 1000, 2000, and 3000 metres, respectively. Results. Alcohol outlets were found to be most available in the two largest metropolitan areas of the province of Quebec (Montréal and Québec City. Within 1000 metres, alcohol outlets are more available in neighbourhoods with the following characteristics: highest concentration of men, least materially deprived highest concentration of persons aged 20 years or more, and location either in a metropolitan area or in a small town. Finally, the number of bars with video lottery terminals increases with the level of social and material deprivation. Conclusion. In Québec, there is no rule governing the location of alcohol outlets. Thus, there is an abundant literature indicating that the regulation of alcohol outlet density could be an effective means of controlling risk attributable to alcohol consumption.

    Full Text Available Abstract Background Use of high daily doses of benzodiazepines is generally contraindicated for seniors. While both patient and physician factors may influence the use of high daily doses, previous research on the effect of patient factors has been extremely limited. The objectives of this study were to determine the one year prevalence of use of high daily doses of benzodiazepines, and examine physician and patient correlates of such use among Quebec community-dwelling seniors. Methods Patient information for 1423 community-dwelling Quebec seniors who participated in the Canadian Study of Health and Aging was linked to provincial health insurance administrative data bases containing detailed information on prescriptions received and prescribers. Results The standardized one year period prevalence of use of high daily doses of benzodiazepines was 7.9%. Use of high daily doses was more frequent among younger seniors and those who had reported anxiety during the previous year. Patients without cognitive impairment were more likely to receive high dose prescriptions from general practitioners, while those with cognitive impairment were more likely to receive high dose prescriptions from specialists. Conclusion High dose prescribing appears to be related to both patient and physician factors.

    In the early 1950s, both the publication of the first Diagnostic and Statistical Manual (DSM-I) and the advent of psychopharmacology - particularly the development of chlorpromazine (Thorazine - RP4650) - set the stage for models of psychiatric thought, research and practice that remain dominant today. It was during this pivotal period, in 1955, that the Département de psychiatrie de l'Université de Montréal was founded by a cohort of young researchers newly arrived from well-known universities in France and the northeastern United States. This influential group quickly became staunch critics of the province's religion-based asylum system and lobbied for a government review that culminated into the 1962 Commission d'étude des hôpitaux psychiatriques (popularly known as the Bédard Report). What followed in Quebec between 1965 and 1975 was the secularization of psychiatric institutions and widespread deinstitutionalization. This paper illuminates cultural changes and intellectual shifts that have been overlooked in historical studies of post-war psychiatry by exploring the expansion of such "anti-psychiatry" schools of thought in Quebec in this period.

  19. The Three Axes of Sociological Practice: The Case of French Quebec

    Directory of Open Access Journals (Sweden)

    Jean-Philippe Warren

    2009-01-01

    Full Text Available In the debate surrounding Michael Burawoy’s plea for public sociology, it is all too often presented as the opposite of the detached, purely objective observation of society. But sociology is not torn between these two poles: the political and the scientific/empirical. Rather, the discipline is structured around three fundamental axes or dimensions: professional, descriptive, and political, embodying three essential aims which, in turn, constitute the respective roles sociology can play in academia and society depending on the specific publics the discipline seeks to address. Acting as professionals, sociologists try to attain prestige by accumulating social or symbolic capital among their colleagues. If they serve science for science’s sake, they find their reward in the advancement of knowledge. If they adopt an activist political stance, they measure the value of their work on a different scale. This paper focuses specifically on French-language sociology in Quebec from the late 19th century to 1970 and argues that the dilemma of juggling these three axes, aims, and roles is one which has deeply influenced not only the discipline as a whole but the generations of Quebec sociologists who have attempted to balance these dimensions in their scholarship. There were three basic schools or approaches during this period, each embedded in the social conditions of its time. Sociologists’ public engagement depended on specific historical conditions much more than it did on personal preferences.

    Referral prioritisation is commonly used in home-based occupational therapy to minimise the negative impacts of waiting, but this practice is not standardised. This may lead to inequities in access to care, especially for clients considered as low priority, who tend to bear the brunt of lengthy waiting lists. This cross-sectional study aimed to describe waiting list management practices targeting low-priority clients in home-based occupational therapy in the province of Quebec, Canada, and to investigate the association between these practices and the length of the waiting list. A structured telephone interview was conducted in 2012-2013 with the person who manages the occupational therapy waiting list in 55 home care programmes across Quebec. Questions pertained to strategies aimed at servicing low-priority clients, the date of the oldest referral and the number of clients waiting. Results were analysed using descriptive statistics and non-parametric tests. The median wait time for the oldest referral was 18 months (range: 2-108 months). A variety of strategies were used to service low-priority clients. Programmes that used no strategies to service low-priority clients (n = 16) had longer wait times (P occupational therapy programmes. However, in programmes where none of these strategies are used, low-priority clients may be denied access to services indefinitely.

    Large inventories of earth embankment dams that require regular maintenance and repairs are managed by both Manitoba Hydro and Hydro-Quebec. A rational procedure was developed for the allocation of limited maintenance and repairs funds while still optimizing dam safety objectives. This paper describes a procedure based on the adaptation of the Condition Indexing procedure initially developed by the United States Army Corps of Engineers, which allows for the allocation of maintenance and repair funds to the components deemed the most important and in the worst condition. The application of the Condition Index procedure was illustrated by examining a sample of different embankment dams operated by Manitoba Hydro and Hydro-Quebec. The primary failure modes are correctly identified by the Condition Index procedure, and it prioritizes the most relevant repair and maintenance activities. This paper describes, and the presents the results of, studies on an embankment dam on limestone foundation, an embankment dam on a clay foundation, and an embankment dam on alluvial soils. 5 refs., 17 tabs.

    In order to ensure public safety, owners and operators of high capacity dams in Quebec have a legal obligation to conduct dam break analysis for each of their dams. Several scenarios of dam failure have been modelled under open water conditions to anticipate the worst-case scenario in terms of downstream consequences. However, the province of Quebec is located north of the 45th parallel, and most of the surface waters are ice covered in the winter. The presence of ice influences the river flow characteristics. As such, it is important to evaluate how ice may change the propagation of a surge wave and other important hydraulic parameters following a dam break. This paper reviewed traditional hydraulic methodologies and models used to perform dam break analyses with particular attention to the presence of ice. The changes in hydraulic processes in river flow involve various physical phenomena, some of which are poorly understood from a theoretical point of view. In the past several years, robust numerical techniques borrowed from fluid mechanics and aerodynamics have resulted in the development of robust hydrodynamic codes that effectively handle irregular bottom geometries, dry bed and mixed flow regimes in reasonable computational times. However, advances are still needed in the understanding of several ice processes, their formulation and their modeling. Data collection that would improve the understanding of the processes is also needed in order to reduce the level of uncertainties associated with the results of dam-break analysis. 22 refs., 3 tabs., 6 figs.

    Objective Juvenile delinquency is one of the major public concerns in many countries. This study aims to document the association between exposure to interparental violence and delinquent behaviors among high school students in Quebec (Canada). Methods A representative sample of 8194 students aged 14–20 years was recruited in Quebec (Canada) high schools. Participants completed a questionnaire describing delinquent behaviors as well as exposure to interparental psychological and physical violence. Findings Overall, one out of two participants has experienced delinquent behaviors and 61.8% of them have reported having been exposed to at least one of the two forms of family violence. Overall, youth exposed to interparental violence are more likely to experience delinquent behaviors. Both psychological and physical interparental violence were significantly and independently associated with delinquent behaviors. Conclusion The findings of this study point out the vulnerability of youth exposed to interparental violence. They also highlight the need in the prevention of juvenile delinquency to focus not only on youth but also on both parents that may have been involved in family violence. PMID:28111591

    After the construction of its wastewater treatment plants, the City of Quebec began to implement overflow control in wet weather to ultimately meet the effluent discharge objectives, i.e. no more than two overflows per summer season in the St. Lawrence River and no more than four in the St-Charles River. After several years of studies to determine which management strategies would best suit the purpose, and to propose optimum solutions, a first project to implement optimal and predictive management in real time, called "Pilot", came to life in 1999. Construction in phases soon followed and the work was completed in the fall of 2009. As a result, requirements with regard to environmental rejects were met in two sectors, namely the St-Charles River and the Jacques-Cartier Beach, and aquatic recreational activities could resume. Meanwhile, the City also worked at giving back access to the water courses to the public by developing sites at the Jacques-Cartier Beach and in the Bay of Beauport, and by rehabilitating the banks of the St-Charles River.

    Global synchronization of general delayed dynamical networks with linear coupling are investigated. A sufficient condition for the global synchronization is obtained by using the linear matrix inequality and introducing a reference state. This condition is simply given based on the maximum nonzero eigenvalue of the network coupling matrix. Moreover, we show how to construct the coupling matrix to guarantee global synchronization of network,which is very convenient to use. A two-dimension system with delay as a dynamical node in network with global coupling is finally presented to verify the theoretical results of the proposed global synchronization scheme.

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

  19. [When women's schools were schools of mothers. The influence of education on the fertility of Quebec women (1850-1940)].

    Science.gov (United States)

    Lalou, R

    1993-01-01

    In Quebec, the relationship between instruction of women and their fertility almost always conforms to hypotheses and traditional theoretical reasonings. The history of education in Quebec contradicts certain sub-vacant theories of explicative models. Until recently, the Quebecois school was not a bearer of new and progressive ideas as the theoretical demographic frameworks demographers thought. On the contrary, due to the strong influence of Catholicism, it tried to maintain the woman in her traditional roles of mother and housewife. Inversely, it is not clear that it allowed girls to acquire the means of their freedom. The Quebecois school did promote birth limitations by the act of educating if not by the contents of its teaching. The school's pronatalist position shaped the collective conscience to respect tradition. The cultural and ideological conservatism of yesterday's school is certainly not an unknown reality of researchers. It is surprising that one must note its persistent absence in demographic studies. The demographers conducting this historical survey of women's schools and fertility do not claim that an approach of the relationship between fertility and education taking in account the cultural and political finality of school would change profoundly the statistical evidence. The evidence shows that the school's emancipatory characteristics did influence the reproductive behavior of Quebec women, but its conservative characteristics probably kept the school from fully contributing to progress. This approach makes us better understand this phenomenon of Quebec history and a little less in terms of some models which are a little too conventional. In conclusion, education in Quebec probably did not have as much impact on fertility decline as fertility decline theories claim.

This paper's objective is to illustrate the importance of electricity trade's impact on GHG emissions by providing an estimate of the net GHG emissions resulting from these trades. To achieve this objective, Quebec hourly electricity exchanges with adjacent jurisdictions were examined over the 2006-2008 period. In order to associate a specific GHG emission quantity to electricity trades, hourly marginal electricity production technologies were identified and validated using the Ontario hourly output per power plant and information released in the Quebec adjacent system operator reports. It is estimated that over three years, imports into Quebec were responsible for 7.7 Mt of GHG, while Quebec hydropower exports avoided 28.3 Mt of GHG emissions. Hence, the net result is 20.6 Mt of avoided emissions over 2006-2008, or about 7 Mt per year, which corresponds to more than 8% of the Quebec yearly GHG emissions. When GHG emissions from all life cycle stages (resource extraction to end-of-life) are accounted for, the net avoided GHG emissions increase by 35%, to 27.9 Mt. - Research highlights: {yields} Environmental benefits of hydropower exports are considerable. {yields} Detailed GHG assessment of such electricity trade is missing from the literature. {yields} Net GHG emissions estimate resulting from such trade is provided. {yields} GHG gains are significant in the Northeast American electricity market due to such electricity trade.

    Projection analyses can provide estimates of the future health burden of increasing BMI and represent a relevant and useful tool for public health planning. Our study presents long-term (2013-2030) projections of the prevalence and numbers of individuals by BMI category for adult men and women in Quebec. Three applications of projections to estimate outcomes more directly pertinent to public health planning, as well as an in-depth discussion of limits, are provided with the aim of encouraging greater use of projection analyses by public health officers. The weighted compositional regression method is applied to prevalence time series derived from sixteen cross-sectional survey cycles, for scenarios of linear change and deceleration. Estimation of the component of projected change potentially amenable to intervention, future health targets and the projected impact on type 2 diabetes, were done. Obesity prevalence in Quebec is projected to rise steadily from 2013 to 2030 in both men (from 18.0-19.4% to 22.2-30.4%) and women (from 15.5-16.3% to 18.2-22.4%). Corresponding projected numbers of obese individuals are (579,000-625,000 to 790,000-1,084,000) in men and (514,000-543,000 to 661,000-816,000) in women. These projected increases are found to be primarily an 'epidemiologic' rather than 'demographic' phenomenon and thus potentially amenable to public health intervention. Assessment of obesity targets for 2020 illustrates the necessity of using projected rather than current prevalence; for example a targeted 2% drop in obesity prevalence relative to 2013 translates into a 3.6-5.4% drop relative to 2020 projected levels. Type 2 diabetes is projected to increase from 6.9% to 9.2-10.1% in men and from 5.7% to 7.1-7.5% in women, from 2011-2012 to 2030. A substantial proportion of this change (25-44% for men, and 27-43% for women) is attributable to the changing BMI distribution. Obesity in Quebec is projected to increase and should therefore continue to be a public

    Full Text Available Questo articolo propone un’analisi storica e una riflessione critica sui modi con cui il Quebec ha affrontato e costantemente riaffronta il problema della scuola pubblica in una società storicamente multiculturale, multietnica e plurilingue. In particolare, la riflessione riguarda il piano normativo e legislativo e le politiche scolastiche via via elaborate, per rispondere alla sfida di pensare e costruire una scuola pubblica capace di costruire una “infanzia quebecchese”. Una lettura del’curricolo ideale’ - si dirà - ci dice poco sulla ‘realtà’ educativa di un paese. Eppure, in Quebec come altrove, le politiche scolastiche costituiscono i segnali pubblici del modo con cui un paese – rappresentando pubblicamente e ufficialmente la sua scuola - rappresenta se stesso, i propri valori, le proprie concezioni di ‘infanzia’. Dopo un breve quadro storico inteso a tracciare l’origine multiculturale del Quebec (come di tutti gli stati nordamericani, par.1, saranno presi in esame la legge 101 (1977 che sancisce il francese come lingua ufficiale di insegnamento e il dibattito sempre vivo e lacerante che ha accompagnato questa legge e le sue successive modifiche (parr. 2-4. In secondo luogo, saranno presi in esame il recente processo di laicizzazione della scuola quebecchese sancito dalla legge 118 (giugno 2000 e le profonde implicazioni culturali, politiche e identitarie di tale processo (parr. 5-8. In un paese che storicamente ha fatto un uso a carattere esplicitamente identitario del riferimento alle religioni dei due gruppi maggioritari, che ha costruito su esso la propria organizzazione sociale, le identità dei gruppi e i loro rapporti di forza, la deconfessionalizzazione della scuola pubblica ha implicazioni e significati culturali del tutto peculiari. Infine sarà analizzata l’assunzione ufficiale della vocazione interculturale della scuola pubblica (parr. 9-11. L’incrocio di questi tagli prospettici fa emergere i

  3. Polymorphic haplotypes on R408BW PKU and normal PAH chromosomes in Quebec and European populations

    The R408W mutation in the phenylalanine hydroxylase gene (PAH) is associated with haplotype 2.3 (RFLP haplotype 2, VNTR 3 of the HindIII system) in most European populations. Another chromosome, first observed in Quebec and then in northwest Europe, carries R408W on haplotype 1.8. The occurrence of the R408W mutation on two different PKU chromosomes could be the result of intragenic recombination, recurrent mutation or gene conversion. In this study, we analyzed both normal and R408W chromosomes carrying 1.8 and 2.3 haplotypes in Quebec and European populations; we used the TCTA{sub (n)} short tandem repeat sequence (STR) at the 5{prime} end of the PAH gene and the HindIII VNTR system at the 3{prime} end of the PAH gene to characterize chromosomes. Fourteen of sixteen R408W chromosomes from {open_quotes}Celtic{close_quotes} families in Quebec and the United Kingdom (UK) harbor a 244 bp STR allele; the remaining two chromosomes, carry a 240 bp or 248bp STR allele. Normal chromosomes (n=18) carry the 240 bp STR allele. R408W chromosomes are different from mutant H1.8 chromosomes; mutant H2.3 carries the 240 bp STR allele (14 of 16 chromosomes) or the 236 allele (2 of 16 chromosomes). The HindIII VNTR comprises variable numbers of 30 bp repeats (cassettes); the repeats also vary in nucleotide sequence. Variation clusters toward the 3{prime} end of cassettes and VNTRs. VNTR 3 alleles on normal H2 (n=9) and mutant R408W H2 (n=19) chromosomes were identical. VNTR 8 alleles on normal H1 chromosomes (n=9) and on R408W H1 chromosomes (n=15) differ by 1 bp substitution near the 3{prime} end of the 6th cassette. In summary, the mutant H1.8 chromosome harboring the R408W mutation has unique features at both the 5{prime} and 3{prime} end of the gene that distinguish it from the mutant H2.3 and normal H1.8 and H2.3 counterparts. The explanation for the occurrence of R408W on two different PAH haplotypes is recurrent mutation affecting the CpG dinucleotide in PAH codon 408.

  4. On network coding for acyclic networks with delays

    Prasad, K

    2011-01-01

    Problems related to network coding for acyclic, instantaneous networks (where the edges of the acyclic graph representing the network are assumed to have zero-delay) have been extensively dealt with in the recent past. The most prominent of these problems include (a) the existence of network codes that achieve maximum rate of transmission, (b) efficient network code constructions, and (c) field size issues. In practice, however, networks have transmission delays. In network coding theory, such networks with transmission delays are generally abstracted by assuming that their edges have integer delays. Note that using enough memory at the nodes of an acyclic network with integer delays can effectively simulate instantaneous behavior, which is probably why only acyclic instantaneous networks have been primarily focused on thus far. In this work, we elaborate on issues ((a), (b) and (c) above) related to network coding for acyclic networks with integer delays, which have till now been overlooked. We show that the...

  5. Nonlinear Control of Delay and PDE Systems

    Science.gov (United States)

    Bekiaris-Liberis, Nikolaos

    In this dissertation we develop systematic procedures for the control and analysis of general nonlinear systems with delays and of nonlinear PDE systems. We design predictor feedback laws (i.e., feedback laws that use the future, rather than the current state of the system) for the compensation of delays (i.e., after the control signal reaches the system for the first time, the system behaves as there were no delay at all) that can be time-varying or state-dependent, on the input and on the state of nonlinear systems. We also provide designs of predic- tor feedback laws for linear systems with constant distributed delays and known or unknown plant parameters, and for linear systems with simultaneous known or unknown constant delays on the input and the state. Moreover, we intro- duce infinite-dimensional backstepping transformations for each particular prob-lem, which enables us to construct Lyapunov-Krasovskii functionals. With the available Lyapunov-Krasovskii functionals we study stability, as well as, robust- ness of our control laws to plant uncertainties. We deal with coupled PDE-ODE systems. We consider nonlinear systems with wave actuator dynamics, for which we design a predictor inspired feedback law. We study stability of the closed-loop system either by constructing Lyapunov functionals, or using arguments of explicit solutions. We also consider linear sys- tems with distributed actuator and sensor dynamics governed by diffusion or wave PDEs, for which we design stabilizing feedback laws. We study stability of the closed-loop systems using Lyapunov functionals that we construct with the intro- duction of infinite-dimensional transformations of forwarding type. Finally, we develop a control design methodology for coupled nonlinear first-order hyperbolic PDEs through an application to automotive catalysts.

  6. Time Delay Cosmography

    2016-01-01

    Gravitational time delays, observed in strong lens systems where the variable background source is multiply-imaged by a massive galaxy in the foreground, provide direct measurements of cosmological distance that are very complementary to other cosmographic probes. The success of the technique depends on the availability and size of a suitable sample of lensed quasars or supernovae, precise measurements of the time delays, accurate modeling of the gravitational potential of the main deflector, and our ability to characterize the distribution of mass along the line of sight to the source. We review the progress made during the last 15 years, during which the first competitive cosmological inferences with time delays were made, and look ahead to the potential of significantly larger lens samples in the near future.

  7. Prediction of delayed subsidence

    Science.gov (United States)

    Burns, K.

    A predictive model of delayed subsidence is discussed. A numerical implementation is tested on one of the best-described study areas, Allegheny County in Pennsylvania. In planning insurance of restitution measures, a predictive model is of value in estimating the magnitude of the problem and the size of long-term budgetary commitments. Contrary to active subsidence, which occurs concurrently with mining operations, or is completed within a few days following coal extraction, delayed subsidence may take many years to appear at the surface after coal mines are abandoned. There are two principal morphological types of delayed subsidence: troughs, which are shallow depressions, and sinks, which are steep-sided crown pits. Both types are damaging to surface structures, and a variety of methods were introduced to deal with the problem, ranging from subsidence insurance to site restitution.

    2016-01-01

    We present here a system with collection of random walks relaying a signal in one dimension with a presence of a delay. We are interested in the time for a signal to travel from one end (start) to the other end (finish) of the lined group of random walkers. It is found that there is an optimal number of walkers for the signal to travel fastest if the delay is present. We discuss implications of this model and associated behaviors to physical and biological systems.

  11. La gestion des gestionnaires de projets: Le cas de l'industrie aerospatiale au Quebec

    Science.gov (United States)

    Petit, Marie-Claude

    This research focuses on the management of project managers (PMs) working in high technology organizations. In particular, it examines how these professionals are taken charge of from a human resources management (HRM) standpoint in firms within the aerospace industry in Quebec. The literature in the field of project management generally depicts PMs as entrepreneurs and resource managers, managing human resources (e.g. project team members) among other things. It also defines them as single-handedly responsible for managing their own career, stress and motivation. This profile suggests that once selected and assigned to projects, PMs receive little attention in terms of HRM from the organization. It is hardly conceivable, however, that PMs would move about completely on their own within the organization, let alone that they wouldn't represent any special challenge in terms of HRM, as the ones the literature so clearly underlines for project team members. The review of the literature also reveals that the subject of HRM as applied to PMs is poorly documented empirically, especially on the topic of what particular challenges the project context might bring up for the HRM of PMs. There is also little told about the actors involved in supporting and contributing to meet the challenges that arise out of managing PMs. This study sought to discern those challenges and the means put forth to address them. Also, it wanted to identify the actors of the HRM of PMs, their roles, their skills, and their relationships, among themselves and with the PMs, in order to efficiently take charge of them. This study also wanted to demonstrate the logic that ties the means put forth by the identified actors with the objectives PM-employing organizations want to reach. Finally, the study wanted to identify the impact of the HRM of PMs as it is occurring in organizations. The Quebec aerospace sector was chosen as the field of research primarily because the success of projects in

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

    2004-11-01

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

    The advent of new technologies and social media offers a host of possibilities for teenagers to consolidate social networks. Unfortunately, new technologies also represent a potential setting for experiences of victimization. The present study explores the prevalence of cyberbullying victimization in a representative sample of 8 194 teenagers in Quebec and the adverse associated consequences. Results indicate that 18% of boys and close to 1 out of 4 girls report at least one incident of cyberbullying in the past 12 months. Cyberbullying victimization contributes to the prediction of low selfesteem and psychological distress over and above other experiences of bullying in schools or other settings. Cyberbullying appear as one important target for the design of prevention and intervention services designed for youth. Copyright © 2014 Elsevier B.V. All rights reserved.

    The goal of the present study was to adapt and to establish normative data for the recently developed Language Screening Test (LAST; Flamand-Roze et al., 2011) in the French-Canadian population according to age and level of education. After an adaptation process, 100 French-Canadian speakers were evaluated with the LAST-Q. As expected, a perfect score of 15/15 was obtained for all high level education participants, and a score of 14/15 was obtained for all participants with a lowest level of education or aged 80 years or more. Thanks to this adaptation, LAST-Q can be used in acute patients in stroke unit in Quebec. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    2016-06-01

    Full Text Available Information and communications technology (ICT has taken centre stage in recent decades in the world of tourism. Publicity and reservation strategies, in particular, are now developed through ICT. The rise of virtual, tourist communities has messed up ways to assess tourism products. This complete renewal of ways to interact with the customer requires tourism businesses to adapt to these new communication patterns. It is with regard to this issue that this study is based. A survey of 2 393 Quebec tourism enterprises made it was possible to identify websites and use patterns of these organizations and social media. The results show that most companies are aware of the importance of ICT for the development of their activities, but some financial, human, geographical and training aspects slow down the process.

    Full Text Available Anticipating the effects of climate change on biodiversity is now critical for managing wild species and ecosystems. Climate change is a global driver and thus affects biodiversity globally. However, land-use planners and natural resource managers need regional or even local predictions. This provides scientists with formidable challenges given the poor documentation of biodiversity and its complex relationships with climate. We are approaching this problem in Quebec, Canada, through the CC-Bio Project (http://cc‑bio.uqar.ca/, using a boundary organization as a catalyst for team work involving climate modelers, biologists, naturalists, and biodiversity managers. In this paper we present the CC-Bio Project and its general approach, some preliminary results, the emerging hypothesis of the northern biodiversity paradox (a potential increase of biodiversity in northern ecosystems due to climate change, and an early assessment of the conservation implications generated by our team work.

Yet in drawing comparisons across Canadianprovinces, cohabitation is far more prevalent in the province of Quebec thanelsewhere. With this in mind, the purpose of the current paper is three fold. First,we set out to briefly situate the recent growth in the number of common-lawunions in Canada and Quebec into a broader historical and international context.Secondly, we review available information from the 2001 Census and the 1998General Social Survey on some of the key socioeconomic and demographiccharacteristics of persons who cohabit relative to those that marry. Thirdly, weconsider how these changes are important to public policy, and of direct interest to legislators andthe Canadian legal system. Major differences are documentedin comparing Quebec with elsewhere in Canada in terms of the education, laborforce participation, median income, income poverty and homeownership. Thedifferences documented between persons who marry relative to cohabiters arefound to be much less in Quebec than elsewhere, in a context wherebycohabitation has become far more widespread, an observation with directimplications for public policy.FrenchLa cohabitation est devenue tant prévalente au Canada qu’elle représenteactuellement le mode d’entrée dans la vie conjugale le plus répandu.

    Mulvihill, P. R.

    1997-12-31

    This study is based on the belief that environmental assessment (EA) can be supportive of viable interdependence between regions and cultures. The central focus is on the scoping stage of the EA conducted for the proposed Great Whale hydroelectric project in northern Quebec. The evaluative framework consists of 16 criteria divided into three interrelated categories, i.e. substantive, general process-oriented and specific process-oriented. The specific process-oriented criteria constitute the primary analytical focus and are the subject of five separate sub-analysis, which reveal various strengths and weaknesses in the performance of the case study. It was concluded that environmental assessment in an intercultural setting is largely within the control of EA panels and the key shortcoming of the process, namely the lack of dialogue between the proponents and the intervenors, could be addressed by making public hearings more dynamic and interactive.

    2014-03-01

    Microalgae are being investigated as potential candidates for biodiesel production since they can be grown without competition with food production, have an inherently fast growth rate, and can have a high lipid content under different nutrient limiting conditions. However, large scale production will best be carried out with indigenous strains, well adapted to local conditions. This study reports on the characterization of the novel microalga Chlorella sp. PCH90, isolated in Quebec. Its molecular phylogeny was established and lipid production studies as a function of the initial concentrations of nitrate, phosphate, and sodium chloride were carried out using response surface methodology. Under the appropriate conditions this microalga could produce up to 36% lipid and grew well in both synthetic medium and secondary effluent from a wastewater treatment plant at both 22 and 10°C. Thus, this strain is promising for further development as a potential biofuels producer under local climatic conditions.

    G. H. Siqueira

    Full Text Available This paper presents fragility curves for the evaluation of a highway bridge retrofitted with seismic isolator devices. The object of this study is the Chemin des Dalles bridge over Highway 55 located in Trois-Rivières in Quebec, Canada. A series of synthetic ground motions time histories compatible with eastern Canada are used to capture the uncertainties related to the hazard. The seismic isolator model represents natural rubber bearing placed under the longitudinal girders over the bents and the abutments of the bridge. NRB isolators are placed in these locations to uncouple the movement of the superstructure and the infrastructure, increasing the flexibility of the system and decreasing the forces transmitted to the infrastructure. Finally, a set of fragility curves for the as-built and retrofitted models are compared to evaluate the effectiveness of seismic isolation to decrease the seismic vulnerability of this bridge.

    2016-07-01

    Full Text Available The concept of sense of place has become central in understanding various modern phenomena in leisure. Tourism promoters in outdoor recreation now emphasize opportunities to bond with nature, with ‘wild’ landscapes or with the authentic value of a destination. However, studying this tourism and recreation issue from the standpoint of ‘place’, which draws upon notions of attendance, identification and social and individual meaning, is lacking in modern studies. This paper, based on a quantitative approach using a questionnaire survey administered to touring skiers in Quebec (n=829, thus aims to present the links between various practice settings and the perceived meaning and identification that skiers attach to their practice sites.

    1996-01-01

    Saguenay Lac-Saint-Jean (SLSJ) is a geographically isolated region of northeastern Quebec in which several autosomal recessive disorders have a high incidence. We calculated the inbreeding coefficients of 567 probands and compared them to 1701 matched control individuals. The mean inbreeding coefficient of the group containing all 567 probands was 2.73 times higher than that of the controls (0.001772 versus 0.00065). Thirteen percent (75/567) of the probands were inbred, but only 5% were born to matings between spouses related as second-degree cousins or closer. No marriage between uncle and niece and only two marriages between first-degree cousins were identified in the disorder group. These results strongly suggest that the high incidence of the autosomal recessive disorders in SLSJ is the result of a founder effect.

    1992-01-01

    Hereditary hemochromatosis (HH) is an autosomal recessive disorder that has a high prevalence in Caucasian populations. Based on HLA typing in 18 families, the gene frequency was estimated 0.12. The homozygote frequency was 0.014 and the heterozygote frequency was 0.21 in Saguenay Lac-Saint-Jean (SLSJ), a geographically isolated region of northeastern Quebec. The genealogical reconstruction showed that 15 of the 57 obligate carriers of the HH gene could be traced back to a unique ancestor in the 18th century. The mean coefficients of inbreeding and kinship were 17 and 15 times, respectively, higher in the HH group than in three control groups. The values of both coefficients were much higher than those found in other HH populations and in most of the other recessive disorders prevalent in SLSJ.

    Cystic fibrosis (CF) is an autosomal recessive disorder with a prevalence at birth estimated at 1/2000-1/2500 livebirths in Caucasian populations. Some 127 CF individuals are known in Saguenay-Lac-St-Jean (SLSJ), a geographically isolated region of Quebec. The prevalence at birth was estimated at 1/902 live borns, and the carrier rate was estimated at 1/15 inhabitants in the SLSJ region. The mean inbreeding coefficient was only slightly elevated in the CF group compared with three control groups, and was due to remote consanguinity. The mean kinship coefficient was 2.4 times higher in the CF group than in the control groups. In SLSJ region, the places of origin of the CF individuals and their parents did not show a clustered nonuniform distribution. Endogamy was not higher in the CF group than in control groups.

  5. New Results on Passivity Analysis of Stochastic Neural Networks with Time-Varying Delay and Leakage Delay

    Directory of Open Access Journals (Sweden)

    YaJun Li

    2015-01-01

    Full Text Available The passivity problem for a class of stochastic neural networks systems (SNNs with varying delay and leakage delay has been further studied in this paper. By constructing a more effective Lyapunov functional, employing the free-weighting matrix approach, and combining with integral inequality technic and stochastic analysis theory, the delay-dependent conditions have been proposed such that SNNs are asymptotically stable with guaranteed performance. The time-varying delay is divided into several subintervals and two adjustable parameters are introduced; more information about time delay is utilised and less conservative results have been obtained. Examples are provided to illustrate the less conservatism of the proposed method and simulations are given to show the impact of leakage delay on stability of SNNs.

    1991-01-01

    Full Text Available Primary biliary cirrhosis (PBC is a rare disease, but is usually recognized because of the characteristic clinical picture and the diagnostic specificity of antimitochondrial antibody (AMA determination. Information on the epitlemiology of PBC is limited. The authors have examined the incidence and prevalence of PBC in the province of Quebec, where all short term hospitals are required to classify discharge summary diagnoses according to the International Classification of Diseases. Code 571.6 designates primary or secondary biliary cirrhosis. The authors reviewed the charts of all patients to whom this code was assigned during a six year period (1980-86. Two hundred and twenty-eight subjects satisfied predetermined diagnostic criteria for PBC. The mean annual incidence rate was 3.9 per 106 population, and the point prevalence in 1986 was 25.4 per 106 population. Ninety-two patients were female, with a mean age at the time of diagnosis of 55.7 years; 89.4% had positive AMA, and 10.5% were asymptomatic. As of January 1, 1989, 126 patients were alive, 91 had died, and 11 had undergone liver transplantation. Cumulative five and 10 year survivals from the time of initial diagnosis were 69% and 49%, respectively. In patients with serum bilirubins greater than 100 μmol/L (n=66, cumulative two year survival was 5.5%. These data indicate that the incidence and prevalence of PBC in Quebec arc similar to chose reported in Ontario and at the lower end of the range of chose reported in western Europe. The clinical features and evolution of PBC are also similar, and serum bilirubin is a major prognostic factor.

    Full Text Available Background: Alcohol and drug use is a serious health problem for many indigenous populations across Canada, including Inuit. The literature on substance use in these populations is too sparse to devise public health interventions. Objective: The present article portrays alcohol and drug use among Inuit living in Nunavik (Northern Quebec between the 1990s and 2000s, and identifies socio-demographic characteristics related to substance use. Design: The Santé Québec Health Survey (1992 and the Nunavik Inuit Health Survey Qanuippitaa (2004 served as databases for this empirical work. Statistical comparisons were made of substance use variables in the 2 samples. Proportions were compared by chi-square tests (p≤0.05 with benchmarking of statistics for all of Quebec and, when available, all of Canada. Results: Alcohol and drug use among Inuit increased significantly between 1992 and 2004, particularly among young adults. Alcohol users consumed significantly more alcohol per drinking episode than other Canadians in both time periods. Considerable cannabis use was widespread. In 2004, no significant differences in frequencies of heavy drinking episodes were observed by gender, with 60% of drug users consuming alcohol on a regular basis. Conclusions: As in other populations from North America, this study profiles the increase in substance use among Inuit from Nunavik in the first part of the last 20 years. We observed distinct substance use patterns among them in comparison to other Canadians. Such findings, if replicated in the coming years, emphasize the need for major, culturally-relevant public health interventions in this population.

    In order to increase CPR training in Quebec, we designed a pilot study to test out the efficacy of training CEGEP (junior college) students in CPR. We tried out four different methods of teaching CPR on students (Group A 'control', 4 h course, manikin to student ratio 1:4; Group B, 4 h course, manikin to student ratio 1:1; Group C, 2 h course, manikin to student ratio 1:1; Group D, video-assisted CPR instruction, manikin to student ratio 1:1). CPR skills were tested on a computerized manikin at the end of the initial course and again at the end of the semester in order to evaluate short and long-term retention of skills. There were no significant differences between the test groups and the control group in terms of compressions or ventilations at the beginning and end of the semester, however groups C and D performed significantly better primary surveys (Airway, Breathing, Circulation - ABC sequences) during the initial testing. The most common reasons reported by students for not taking CPR courses were the cost of courses (49.2%) and the inconvenience of courses (26.2%), similarly the two most common incentives which could get students to take CPR courses were; free courses (65.6%) and greater accessibility of courses (54.1%). Video-assisted CPR training appears to be feasible, enjoyable and as, if not more effective than traditional CPR courses. Instituting a mandatory video-assisted CPR program in the CEGEP system in Quebec and in high schools and colleges throughout the world, would be a cost-effective way to train massive amounts of young people in CPR.

    Full Text Available BACKGROUND: Although interruption of endemic measles was achieved in the Americas in 2002, Quebec experienced an outbreak in 2011 of 776 reported cases; 80% of these individuals had not been fully vaccinated. We analyzed readers' online responses to Canadian news articles regarding the outbreak to better understand public perceptions of measles and vaccination. METHODS: We searched Canadian online English and French news sites for articles posted between April 2011 and March 2012 containing the words "measles" and "Quebec". We included articles that i concerned the outbreak or related vaccination strategies; and ii generated at least ten comments. Two English and two bilingual researchers coded the unedited comments, categorizing codes to allow themes to emerge. RESULTS: We analyzed 448 comments from 188 individuals, in response to three French articles and six English articles; 112 individuals expressed positive perceptions of measles vaccination (2.2 comments/person, 38 were negative (4.2 comments/person, 11 had mixed feelings (1.5 comments/person, and 27 expressed no opinion (1.1 comments/person. Vaccine-supportive themes involved the success of vaccination in preventing disease spread, societal responsibility to vaccinate for herd immunity, and refutation of the autism link. Those against measles vaccination felt it was a personal rather than societal choice, and conveyed a distrust of vaccine manufacturers, believing that measles infection is not only safe but safer than vaccination. Commenters with mixed feelings expressed uncertainty of the infection's severity, and varied in support of all vaccines based on perceived risk/benefit ratios. CONCLUSION: The anti-vaccine minority's volume of comments translates to a disproportionately high representation on online boards. Public health messages should address concerns by emphasizing that immunization is always a personal choice in Canada, and that the pharmaceutical industry is strictly

    Full Text Available Background: In 2000, an outbreak of severe pneumonia caused by a virulent clone of serotype 1 Streptococcus pneumoniae was detected in the Nunavik region of Quebec. A mass immunization campaign was implemented in the spring of 2002, targeting persons ≥5 years of age and using the 23-valent pneumococcal polysaccharide vaccine (PPSV23. At the same time, the 7-valent pneumococcal conjugate vaccine (PCV7 was introduced into the routine immunization programme of infants, with catch-up for children up to 4 years of age. Objectives: To describe the epidemiology of invasive pneumococcal disease (IPD in relation to PPSV23 and PCV7 use. Study design and methods: Retrospective analysis of IPD cases identified by the Quebec public health laboratory during the period 1997–2010. Results: A total of 82 IPD cases were identified during the study period. In adults, serotype 1 incidence decreased following the 2002 PPSV23 mass campaign but breakthrough cases continued to occur. Following PCV7 use in children, there was a decrease in the incidence of vaccine-type IPD and replacement by other serotypes in adults. In children, a marked decrease in the annual incidence of serotypes included in PCV7 was observed following PCV7 introduction: 162/100,000 in 1997–2001 vs. 10/100,000 in 2004–2010 (p<0.01. Concomitantly, the incidence of IPD caused by serotypes not included in PCV7 increased from 29/100,000 to 109/100,000 (p=0.11. Conclusion: The mass immunization campaign using the PPSV23 in 2002 and the introduction of PCV7 for the routine immunization of infants induced important modifications in the epidemiology of IPD. IPD rates in Nunavik remain much higher than in the southern part of the province both in children and adults. More effective pneumococcal vaccines are needed to eliminate geographic disparities in IPD risk.

    Full Text Available Since agriculture directly contributes to global anthropogenic greenhouse gas (GHG emissions, integrating trees into agricultural landscapes through agroforestry systems is a viable adaptive strategy for climate change mitigation. The objective of this study was to evaluate the carbon (C sequestration and financial benefits of C sequestration according to Quebec’s Cap-and-Trade System for Greenhouse Gas Emissions Allowances (C & T System or the Système de plafonnement et d’échange de droits d’émission de gaz à effet de serre du Québec (SPEDE program for two experimental 10-year-old tree-based intercropping (TBI systems in southern Quebec, Canada. We estimated total C stored in the two TBI systems with hybrid poplar and hardwoods and adjacent non-TBI systems under agricultural production, considering soil, crop and crop roots, litterfall, tree and tree roots as C stocks. The C sequestration of the TBI and adjacent non-TBI systems were compared and the market value of the C payment was evaluated using the net present value (NPV approach. The TBI systems had 33% to 36% more C storage than adjacent non-TBI systems. The financial benefits of C sequestration after 10 years of TBI practices amounted to of $2,259–$2,758 CAD ha−1 and $1,568–$1,913 CAD ha−1 for St. Edouard and St. Paulin sites, respectively. We conclude that valorizing the C sequestration of TBI systems could be an incentive to promote the establishment of TBI for the purpose of GHG mitigation in Quebec, Canada.

    After a decade of extensive dismantling and reconstruction, changes in the downstream refining and marketing side of the petroleum industry have progressed to the point where downstream assets are once again considered to be among the strongest and most vital parts of the industry. Merchandising has become a way of life in gasoline service stations to the point where the service station of the 21. century will likely carry mass-consumption items from panty hose to sandwiches in addition to gasoline. Petro-Canada is in the forefront of rolling out the new-image service stations, while high traffic Esso locations are adding cafes serving doughnuts, muffins, bagels, soup and sandwiches in partnership with the Tim Horton's chain. In Canada, Quebec is way ahead of the other provinces in setting the high tone in the business of catering to consumers on wheels as demonstrated by the 1,932 retail sites of 'Couche-Tard', a name synonymous with gas pumps, fresh coffee and the myriad items offered in traditional convenience stores. With a total of 1,693 stores in Canada, 239 in the United States, 13,000 plus employees and more than 800 gas pumps (80 of them branded to in-house gasoline) Couche-Tard is the ninth largest convenience retailer in North America. The article describes the rise to prominence of the Couche-Tard empire, explains why circumstances in Quebec were ripe for this type of development, and offers a glimpse into the future of the likely further development of the retail gasoline market in the rest of Canada.

    FIFO is perhaps the simplest scheduling discipline. For single-class FIFO, its delay guarantee performance has been extensively studied: The well-known results include a stochastic delay bound for $GI/GI/1$ by Kingman and a deterministic delay bound for $D/D/1$ by Cruz. However, for multiclass FIFO, few such results are available. To fill the gap, we prove delay bounds for multiclass FIFO in this work, considering both deterministic and stochastic cases.

    Abstract Background: Traumatic diaphragmatic hernias (TDHs) are sometimes difficult to identify at an early stage and can consequently result in diagnostic delays with life-threatening outcomes. It is the aim of this case study to highlight the difficulties encountered with the earlier detection of traumatic diaphragmatic hernias. Methods: Clinical data of patients who received treatment for delayed traumatic diaphragmatic hernias in registers of the First Affiliated Hospital of Xi’an Jiaotong University from 1998 to 2014 were analyzed retrospectively. Results: Six patients were included in this study. Left hemidiaphragm was affected in all of them. Most of the patients had a history of traffic accident and 1 a stab-penetrating injury. The interval from injury to developing symptoms ranged from 2 to 11 years (median 5 years). The hernial contents included the stomach, omentum, small intestine, and colon. Diaphragmatic injury was missed in all of them during the initial managements. All patients received operations once the diagnosis of delayed TDH was confirmed, and no postoperative mortality was detected. Conclusions: Delayed TDHs are not common, but can lead to serious consequences once occurred. Early detection of diaphragmatic injuries is crucial. Surgeons should maintain a high suspicion for injuries of the diaphragm in cases with abdominal or lower chest traumas, especially in the initial surgical explorations. We emphasize the need for radiographical follow-up to detect diaphragmatic injuries at an earlier stage. PMID:27512848

    Full Text Available The main purpose of this paper wants to investigate the optimal retailer's lot-sizing policy with two warehouses under partially permissible delay in payments within the economic order quantity (EOQ framework. In this paper, we want to extend that fully permissible delay in payments to the supplier would offer the retailer partially permissible delay in payments. That is, the retailer must make a partial payment to the supplier when the order is received. Then the retailer must pay off the remaining balance at the end of the permissible delay period. In addition, we want to add the assumption that the retailer's storage space is limited. That is, the retailer will rent the warehouse to store these exceeding items when the order quantity is larger than retailer's storage space. Under these conditions, we model the retailer's inventory system as a cost minimization problem to determine the retailer's optimal cycle time and optimal order quantity. Three theorems are developed to efficiently determine the optimal replenishment policy for the retailer. Finally, numerical examples are given to illustrate these theorems and obtained a lot of managerial insights.

    Photosynthesis is a very efficient photochemical process. Nevertheless, plants emit some of the absorbed energy as light quanta. This luminescence is emitted, predominantly, by excited chlorophyll a molecules in the light-harvesting antenna, associated with Photosystem II (PS II) reaction centers. The emission that occurs before the utilization of the excitation energy in the primary photochemical reaction is called prompt fluorescence. Light emission can also be observed from repopulated excited chlorophylls as a result of recombination of the charge pairs. In this case, some time-dependent redox reactions occur before the excitation of the chlorophyll. This delays the light emission and provides the name for this phenomenon-delayed fluorescence (DF), or delayed light emission (DLE). The DF intensity is a decreasing polyphasic function of the time after illumination, which reflects the kinetics of electron transport reactions both on the (electron) donor and the (electron) acceptor sides of PS II. Two main experimental approaches are used for DF measurements: (a) recording of the DF decay in the dark after a single turnover flash or after continuous light excitation and (b) recording of the DF intensity during light adaptation of the photosynthesizing samples (induction curves), following a period of darkness. In this paper we review historical data on DF research and recent advances in the understanding of the relation between the delayed fluorescence and specific reactions in PS II. An experimental method for simultaneous recording of the induction transients of prompt and delayed chlorophyll fluorescence and decay curves of DF in the millisecond time domain is discussed.

    Full Text Available Byssinosis, a chronic lung disease of cotton mill workers, is characterized by repeated episodes of reversible airway obstruction, which can lead to permanent alterations of lung function. When this occurs in Quebec the worker must be removed from further exposure in accordance with the provincial compensation rules. The current Quebec Occupational Safety and Health Regulation has a permissible exposure limit of 500 μg/m3, resulting in a prevalence rate of byssinosis of 2% to 5% in cotton workers. In this study the incidence of new respiratory disorders in persons employed in Quebec cotton mills from 1980 to 1995 was assessed and factors that identified byssinosis cases were analyzed. Incidence of the disease was assessed on the basis of cases referred to the Commission de Santé & Sécurité au travail du Québec (Quebec Workers’ Compensation Board from all Quebec textile plants. Analyses of age, years of employment, job description, smoking history, bronchial reactivity and lung function before and at work were used for diagnostic purposes. Incidence of new byssinosis cases from 1990 to 1995 was 2.8 cases per year per 5000 workers, slightly above the incidence from 1980 to 1989, at 1.7 cases per year. The incidence of chronic cases was stable at 1.5 cases per year, whereas that of early cases increased from 0.3 cases per year (1980 to 1989 to 1.25 cases per year (1990 to 1995. In comparison with chronic byssinosis cases, the average time of work before symptom appearance was 17±4 versus 32±1 years, P<0.001. Bronchial reactivity to methacholine (PC20 at work was below 2 mg/mL in 100% of byssinosis cases versus 14% in subjects not diagnosed with byssinosis. Decreases in forced expiratory volume in 1 s (FEV1 at work averaged 30% in the byssinosis and 6% in the nonbyssinosis subjects; peak flow rates were not different between those with and those without byssinosis. Early byssinosis cases were from three distinct plants in different

    Full Text Available Delay in construction projects is a situation where the project cannot be completed under the planned time. It is a common issue faced in the construction industry all over the world especially in developing countries. In the Malaysian construction industry, 17.3% of construction projects experience more than 3 months delay and some of them are abandoned. Hence, the study of factors contributing to delay is very important in order to reduce the number of projects that experience delay in project delivery. Three objectives of the research have been formulated, namely (1 to identify factors that contribute to delay in construction projects; (2 to analyse and rank the causes of delay rated by contractors; and (3 to study the effects of delay in construction projects. One hundred questionnaires were distributed during data collection stage and only 36 responses received. The respondents only consist of contractors and sub-contractors because the scope of the research focuses on contractors' perception. The data collected was analysed using SPSS software. Seven factors that contribute to delay were identified through literature review, namely contractors' financial difficulties, construction mistakes and defective work, labour shortage, coordination problems, shortage of tools and equipment, material shortage and poor site management. Of those factors, the three most important factors were found to be labour shortage, contractors' financial difficulties and construction mistakes and defective works. Besides project delay, the research shows that cost overrun and extension of time (EOT are the most common effects of delay in construction projects.

    In this paper, a class of recurrent neural networks with multi-proportional delays is studied. The nonlinear transformation transforms a class of recurrent neural networks with multi-proportional delays into a class of recurrent neural networks with constant delays and time-varying coefficients. By constructing Lyapunov functional and establishing the delay differential inequality, several delay-dependent and delay-independent sufficient conditions are derived to ensure global exponential periodicity and stability of the system. And several examples and their simulations are given to illustrate the effectiveness of obtained results.

    Within the framework of 'Network Physiology', we ask a fundamental question of how modulations in cardiac dynamics emerge from networked brain-heart interactions. We propose a generalized time-delay approach to identify and quantify dynamical interactions between physiologically relevant brain rhythms and the heart rate. We perform empirical analysis of synchronized continuous EEG and ECG recordings from 34 healthy subjects during night-time sleep. For each pair of brain rhythm and heart interaction, we construct a delay-correlation landscape (DCL) that characterizes how individual brain rhythms are coupled to the heart rate, and how modulations in brain and cardiac dynamics are coordinated in time. We uncover characteristic time delays and an ensemble of specific profiles for the probability distribution of time delays that underly brain-heart interactions. These profiles are consistently observed in all subjects, indicating a universal pattern. Tracking the evolution of DCL across different sleep stages, we find that the ensemble of time-delay profiles changes from one physiologic state to another, indicating a strong association with physiologic state and function. The reported observations provide new insights on neurophysiological regulation of cardiac dynamics, with potential for broad clinical applications. The presented approach allows one to simultaneously capture key elements of dynamic interactions, including characteristic time delays and their time evolution, and can be applied to a range of coupled dynamical systems.

Este ensaio propõe-se a levantar a situação das políticas ambientais governamentais, principalmente no Quebec, que adotou em abril de 2006 a lei sobre o desenvolvimento sustentável. Nessa linha argumentativa, considero as mudanças no contexto dos recentes avanços das biotecnologias, que nos conferem sobretudo poderes até recentemente desconhecidos sobre a natureza, a vida e o ser humano. As diversas formas de intervenção dos governos do Canadá e do Quebec revelam um nítido crescimento da presença ativa do Estado, não somente nos setores tradicionais, mas também na bioindústria, onde o governo intervém cada vez mais. Os desafios, consequências e questões dessa realidade serão tratados sob a ótica de um novo humanismo.To a certain extent, the technical-scientific advances have allowed us to "tame" nature. This essay examines the situation of the governmental environmental policies, especially that of the state of Quebec, which adopted the law of sustainable development in April 2006. In this line of argument, this article considers the changes in the context of the recent advances in biotechnology, which give us an unprecedented power over nature, life and human beings. The diverse forms of intervention, from the governments of Canada and Quebec, are indicative of an increase in the active presence of the State, not only in the traditional sectors, but also in the bio-industry, in which the government intervenes more and more. The challenges, consequences and issues of this reality will be addressed from the perspective of a new humanism.

    Full Text Available The Kingdom of Saudi Arabia (KSA has witnessed a huge increase in construction during the last two decades. However, many projects experienced time delays, cost overruns and the generation of massive amounts of waste. To address these challenges, lean construction has been introduced into the Saudi construction industry; however, it is still in its infancy. This study therefore investigates the current state of lean construction implementation in the construction industry in the KSA. The objectives are to identify: the types of construction waste, level of use of tools that support the implementation of lean construction, stages of application of lean methods, and the benefits of lean construction. To achieve these objectives, a structured questionnaire survey of 282 construction professionals was carried out. After the analysis of the collected data using mean score and Anova test, the following conclusions were made.  In the construction industry in the KSA, waiting is the most common type of waste, while Computer Aided Design (CAD is the conventional tool supporting the implementation of lean construction. Furthermore, the data suggests that lean construction is most commonly used in the construction stage of projects while customer satisfaction is the main benefit derived from lean construction practices. This study concludes that the level of implementation of lean construction in the KSA construction industry is increasing. The results will help benchmark the current state of lean construction implementation, which will enable the construction industry to identify strategies to implement lean construction in Saudi Arabia in accordance with their needs and project goals, to achieve better productivity.

The proposed method is passivity-based controllers with time varying gains which depend on the rate of change of time varying delay. In our proposed method, stability condition is independent of the magnitude of the communication delay and the damping of the system. The delay-independent stability is shown via Lyapunov stability methods. Several experimental results show the effectiveness o...

    An ethnographic study was undertaken in two rural areas of Quebec to conceptualize the good death. The findings reveal that a good quality of life for the dying person and his or her family and friends is essential for a good death. The resulting conceptual model emphasized four dimensions: physical, spiritual, social, and emotiona/psychological. These dimensions were determined to be similar to those discovered through a previous urban study, indicating that there may be considerable overlap between good deaths in rural and urban areas. Some findings of this Quebec French-language rural study were similar to those of an Alberta English-language rural study, indicating that rural people may have some common needs and interests with regard to the good death. As such, there could be some common elements of the good death that transcend culture or ethnicity. Chief among these is the desire of rural people to die at home or in their home communities.

  11. Low Fertility in Canada: The Nordic Model in Quebec and the U.S. Model in Alberta

    2010-01-01

    Full Text Available Among the factors that are responsible for low fertility, the risks experienced by young people are particularly relevant. In that context, it is noteworthy that fertility is rising most in Alberta and Quebec, that is in provinces where young families have had the security of either good job opportunities or supportive social policy. The fertility trend in Canada has seen a low point of 1.51 in 2002, rising to a total fertility rate of 1.66 in 2007. The trends and differences are placed in the context of family and work questions, including the division of paid and unpaid work by gender. By marital status, family structure and work orientation, fertility is highest for women and men who are married, with no step children and intermediate work orientation. We summarize the changing policy context, proposing that social policy has become more supportive of families with young children, especially in Quebec but also in the rest of Canada.

  12. Quality of Physiotherapy Services for Injured Workers Compensated by Workers' Compensation in Quebec: A Focus Group Study of Physiotherapy Professionals

    2015-01-01

    Musculoskeletal disorders are among the leading causes of work-related physical disability in the province of Quebec in Canada. The authors conducted a focus group study with physiotherapists and physical rehabilitation therapists working with patients whose treatments are compensated by the Quebec Workers' Compensation Board with the goal of exploring quality of care and ethical issues. Three main themes were identified: (1) systemic factors, (2) complexity in treatment decisions and (3) inequality of care. Although physiotherapy professionals strive to give these patients the best possible care, patients might not always be provided with optimal or equal treatment. When compared with other patients, there appear to be differences with respect to access to care and types of services offered to injured workers, raising equity concerns. Factors that shape and constrain quality of physiotherapy services for injured workers need to be addressed to improve care for these patients. PMID:25947032

    We briefly discuss the method of population synthesis to calculate theoretical delay time distributions of type Ia supernova progenitors. We also compare the results of the different research groups and conclude that although one of the main differences in the results for single degenerate progenitors is the retention efficiency with which accreted hydrogen is added to the white dwarf core, this cannot explain all the differences.

This is because the noise in the laser light is common to both arms, experiencing exactly the same delay, and thus cancels when it is differenced at the photo detector. In this situation, much lower level secondary noises then set overall performance. If, however, the two arms have different lengths (...

    2010-01-01

    We analyze the time delay between emission of photoelectrons from the outer valence $ns$ and $np$ sub-shells in noble gas atoms following absorption of an attosecond XUV pulse. By solving the time dependent Schr\\"odinger equation and carefully examining the time evolution of the photoelectron wave packet, we establish the apparent "time zero" when the photoelectron leaves the atom. Various processes such as elastic scattering of the photoelectron on the parent ion and many-electron correlation affect the quantum phase of the dipole transition matrix element, the energy dependence of which defines the emission timing. This qualitatively explains the time delay between photoemission from the $2s$ and $2p$ sub-shells of Ne as determined experimentally by attosecond streaking [{\\em Science} {\\bf 328}, 1658 (2010)]. However, with our extensive numerical modeling, we were only able to account for less than a half of the measured time delay of $21\\pm5$~as. We argue that the XUV pulse alone cannot produce such a larg...

    Full Text Available Equal-arm detectors of gravitational radiation allow phase measurements many orders of magnitude below the intrinsic phase stability of the laser injecting light into their arms. This is because the noise in the laser light is common to both arms, experiencing exactly the same delay, and thus cancels when it is differenced at the photo detector. In this situation, much lower level secondary noises then set the overall performance. If, however, the two arms have different lengths (as will necessarily be the case with space-borne interferometers, the laser noise experiences different delays in the two arms and will hence not directly cancel at the detector. In order to solve this problem, a technique involving heterodyne interferometry with unequal arm lengths and independent phase-difference readouts has been proposed. It relies on properly time-shifting and linearly combining independent Doppler measurements, and for this reason it has been called time-delay interferometry (TDI. This article provides an overview of the theory, mathematical foundations, and experimental aspects associated with the implementation of TDI. Although emphasis on the application of TDI to the Laser Interferometer Space Antenna (LISA mission appears throughout this article, TDI can be incorporated into the design of any future space-based mission aiming to search for gravitational waves via interferometric measurements. We have purposely left out all theoretical aspects that data analysts will need to account for when analyzing the TDI data combinations.

  1. Identity profiles and well-being of multicultural immigrants: The case of Canadian immigrants living in Quebec

    Directory of Open Access Journals (Sweden)

    Joelle eCarpentier

    2013-02-01

    Full Text Available Studies worldwide point toward increased risk of mental health issues among immigrants. Immigrants’ ability to integrate the cultural identity of their new country has been found to be a key factor in their psychological well-being. Even though researchers agree on the crucial role of identity integration in immigrants’ well-being, the current literature has two main limitations: 1 researchers do not agree on the importance that should be allocated to each of the cultural identities, and 2 research has focused on bicultural individuals as opposed to multicultural individuals. The present paper proposes to study Canadians immigrants living in the province of Quebec who, because of the political and linguistic situation of the province, face the challenge of integrating two new cultural identities (Quebecer and Canadian to their original one. Specifically, cluster analysis was used to observe identity profiles that naturally emerge among 120 Canadian immigrants from the province of Quebec. Identity profiles were then compared on various indices of well-being to identify the optimal identity structure. In total, four identity profiles emerged, differing in their levels of identity coherence (i.e., similar levels of identification with each group and identification to either the original group or the Quebecers. ANOVA results confirmed that identity profiles differed in their average level of well-being. First, immigrants with coherent profiles displayed higher levels of well-being. Second, among incoherent profiles, the profile where identification to the original group is the highest showed the greatest well-being. Implications suggest that in order to maximize immigrants’ well-being, psychologists should focus on the coherence between cultural groups as well as identification to the original group.

    We propose a straightforward extension of symbolic transfer entropy to enable the investigation of delayed directional relationships between coupled dynamical systems from time series. Analyzing time series from chaotic model systems, we demonstrate the applicability and limitations of our approach. Our findings obtained from applying our method to infer delayed directed interactions in the human epileptic brain underline the importance of our approach for improving the construction of functional network structures from data.

  6. Development of a methodology to evaluate probable maximum precipitation (PMP) under changing climate conditions: Application to southern Quebec, Canada

    2014-11-01

    Climate change (CC) needs to be accounted for in the estimation of probable maximum floods (PMFs). However, there does not exist a unique way to estimate PMFs and, furthermore the challenge in estimating them is that they should neither be underestimated for safety reasons nor overestimated for economical ones. By estimating PMFs without accounting for CC, the risk of underestimation could be high for Quebec, Canada, since future climate simulations indicate that in all likelihood extreme precipitation events will intensify. In this paper, simulation outputs from the Canadian Regional Climate Model (CRCM) are used to develop a methodology to estimate probable maximum precipitations (PMPs) while accounting for changing climate conditions for the southern region of the Province of Quebec, Canada. The Kénogami and Yamaska watersheds are herein of particular interest, since dam failures could lead to major downstream impacts. Precipitable water (w) represents one of the key variables in the estimation process of PMPs. Results of stationary tests indicate that CC will not only affect precipitation and temperature but also the monthly maximum precipitable water, wmax, and the ensuing maximization ratio used for the estimation of PMPs. An up-to-date computational method is developed to maximize w using a non-stationary frequency analysis, and then calculate the maximization ratios. The ratios estimated this way are deemed reliable since they rarely exceed threshold values set for Quebec, and, therefore, provide consistent PMP estimates. The results show an overall significant increase of the PMPs throughout the current century compared to the recent past.

  7. Delayed transiently chaotic neural networks and their application

    Chen, Shyan-Shiou

    2009-09-01

    In this paper, we propose a novel model, a delayed transiently chaotic neural network (DTCNN), and numerically confirm that the model performs better in finding the global minimum for the traveling salesman problem (TSP) than the traditional transiently chaotic neural network. The asymptotic stability and chaotic behavior of the dynamical system with time delay are fully discussed. We not only theoretically prove the existence of Marotto's chaos for the delayed neural network without the cooling schedule by geometrically constructing a transversal homoclinic orbit, but we also discuss the stability of nonautonomous delayed systems using LaSalle's invariance principle. The result of the application to the TSP by the DTCNN might further explain the importance of systems with time delays in the neural system.

  8. Linearized oscillation theory for a nonlinear delay impulsive equation

    2003-12-01

    For a scalar nonlinear impulsive delay differential equationwith rk(t)≥0,hk(t)≤t, limj-->∞ τj=∞, such an auxiliary linear impulsive delay differential equationis constructed that oscillation (nonoscillation) of the nonlinear equation can be deduced from the corresponding properties of the linear equation. Coefficients rk(t) and delays are not assumed to be continuous. Explicit oscillation and nonoscillation conditions are established for some nonlinear impulsive models of population dynamics, such as the impulsive logistic equation and the impulsive generalized Lasota-Wazewska equation which describes the survival of red blood cells. It is noted that unlike nonimpulsive delay logistic equations a solution of a delay impulsive logistic equation may become negative.

    This paper studies the asymptotic stability for a class of neutral systems with mixed time-varying delays. Through utilizing some Wirtinger-based integral inequalities and extending the convex combination technique, the upper bound on derivative of Lyapunov-Krasovskii (L-K) functional can be estimated more tightly and three mixed-delay-dependent criteria are proposed in terms of linear matrix inequalities (LMIs), in which the nonlinearity and parameter uncertainties are also involved, respectively. Different from those existent works, based on the interconnected relationship between neutral delay and state one, some novel triple integral functional terms are constructed and the conservatism can be effectively reduced. Finally, two numerical examples are given to show the benefits of the proposed criteria. Copyright © 2017 ISA. Published by Elsevier Ltd. All rights reserved.

    By using the fact that the neuron activation functions are sector bounded and nondecreasing, this brief presents a new method, named the delay-slope-dependent method, for stability analysis of a class of recurrent neural networks with time-varying delays. This method includes more information on the slope of neuron activation functions and fewer matrix variables in the constructed Lyapunov-Krasovskii functional. Then some improved delay-dependent stability criteria with less computational burden and conservatism are obtained. Numerical examples are given to illustrate the effectiveness and the benefits of the proposed method.

    In this paper, we propose a method for the projective synchronization between two different chaotic systems with variable time delays. Using active control approach, the suitable controller is constructed to make the states of two different diverse time delayed systems asymptotically synchronize up to the desired scaling factor. Based on the Lyapunov stability theory, the sufficient condition for the projective synchronization is calculated theoretically. Numerical simulations of the projective synchronization between Maekey-Glass system and Ikeda system with variable time delays are shown to validate the effectiveness of the proposed algorithm.

Two numerical examples show the effectiveness of the obtained results.

    2004-01-01

    This paper is concerned with delay dependent absolute stability for a class of uncertain Lur′e systems with multiple time-delays. By using a descriptor model transformation of the sys-tem and by applying a recent result on bounding of cross products of vectors, a new type of Lya-punov-Krasovskii functional is constructed. Based on the new functional, delay-dependent suffi-cient conditions for absolute stability are derived in terms of linear matrix inequalities. These con-ditions do not require any parameter tuning, and can be solved numerically using the software LMI Lab. A numerical example is presented which shows that the proposed method can substantiallyimprove the delay bound for absolute stability of Lur′e system with time-delays, compared to theexisting ones.

    In this paper, the stability analysis of linear systems with an interval time-varying delay is investigated. First, augmented Lyapunov-Krasovskii functionals are constructed, which include more information of the delay's range and the delay's derivative. Second, two improved integral inequalities, which are less conservative than Jensen's integral inequalities, and delay-range-partition approach are utilised to estimate the upper bounds of the derivatives of the augmented Lyapunov-Krasovskii functionals. Then, less conservative stability criteria are proposed no matter whether the lower bound of delay is zero or not. Finally, to illustrate the effectiveness of the stability criteria proposed in this paper, two numerical examples are given and their results are compared with the existing results.

    Full Text Available The impulsive complex-valued neural networks with three kinds of time delays including leakage delay, discrete delay, and distributed delay are considered. Based on the homeomorphism mapping principle of complex domain, a sufficient condition for the existence and uniqueness of the equilibrium point of the addressed complex-valued neural networks is proposed in terms of linear matrix inequality (LMI. By constructing appropriate Lyapunov-Krasovskii functionals, and employing the free weighting matrix method, several delay-dependent criteria for checking the global μ-stability of the complex-valued neural networks are established in LMIs. As direct applications of these results, several criteria on the exponential stability, power-stability, and log-stability are obtained. Two examples with simulations are provided to demonstrate the effectiveness of the proposed criteria.

    2013-01-01

    Delaying gratification involves two components: (i) delay choice (selecting a delayed reward over an immediate one), and (ii) delay maintenance (sustaining the decision to delay gratification even if the immediate reward is available during the delay). In primates, two tasks most commonly have explored these components, the Intertemporal choice task and the Accumulation task. It is unclear whether these tasks provide equivalent measures of delay of gratification. Here, we compared the performance of the same capuchin monkeys, belonging to two study populations, between these tasks. We found only limited evidence of a significant correlation in performance. Consequently, in contrast to what is often assumed, our data provide only partial support to the hypothesis that these tasks provide equivalent measures of delay of gratification. PMID:23544770

    Full Text Available In three studies, we examined factors that may temporarily attenuate information search. People are generally curious and dislike uncertainty, which typically encourages them to look for relevant information. Despite these strong forces that promote information search, people sometimes deliberately delay obtaining valuable information. We find they may do so when they are concerned that the information might interfere with future pleasurable activities. Interestingly, the decision to search or to postpone searching for information is influenced not only by the value and importance of the information itself but also by well-being maintenance goals related to possible detrimental effects that negative knowledge may have on unrelated future plans.

    CERN Document Server

    Ling, Zhou; Yu-xi, Zhu; 10.5121/ijcnc.2010.2212

    2010-01-01

    Multicast is the ability of a communication network to accept a single message from an application and to deliver copies of the message to multiple recipients at different location. With the development of Internet, Multicast is widely applied in all kinds of multimedia real-time application: distributed multimedia systems, collaborative computing, video-conferencing, distance education, etc. In order to construct a delay-constrained multicast routing tree, average distance heuristic (ADH) algorithm is analyzed firstly. Then a delay-constrained algorithm called DCADH (delay-constrained average distance heuristic) is presented. By using ADH a least cost multicast routing tree can be constructed; if the path delay can't meet the delay upper bound, a shortest delay path which is computed by Dijkstra algorithm will be merged into the existing multicast routing tree to meet the delay upper bound. Simulation experiments show that DCADH has a good performance in achieving a low-cost multicast routing tree.

    2016-12-01

    The dynamics of second-order equations with nonlinear delayed feedback and a large coefficient of a delayed equation is investigated using asymptotic methods. Based on special methods of quasi-normal forms, a new construction is elaborated for obtaining the main terms of asymptotic expansions of asymptotic residual solutions. It is shown that the dynamical properties of the above equations are determined mostly by the behavior of the solutions of some special families of parabolic boundary value problems. A comparative analysis of the dynamics of equations with the delayed feedback of three types is carried out.

    Full Text Available This paper discusses the mean-square exponential stability of uncertain neutral linear stochastic systems with interval time-varying delays. A new augmented Lyapunov-Krasovskii functional (LKF has been constructed to derive improved delay-dependent robust mean-square exponential stability criteria, which are forms of linear matrix inequalities (LMIs. By free-weight matrices method, the usual restriction that the stability conditions only bear slow-varying derivative of the delay is removed. Finally, numerical examples are provided to illustrate the effectiveness of the proposed method.

    Taylor, S. Richard; Campbell, Sue Ann

    2007-04-01

    Chaotic saddles are unstable invariant sets in the phase space of dynamical systems that exhibit transient chaos. They play a key role in mediating transport processes involving scattering and chaotic transients. Here we present evidence (long chaotic transients and fractal basins of attraction) of transient chaos in a “logistic” delay differential equation. We adapt an existing method (stagger-and-step) to numerically construct the chaotic saddle for this system. This is the first such analysis of transient chaos in an infinite-dimensional dynamical system, and in delay differential equations in particular. Using Poincaré section techniques we illustrate approaches to visualizing the saddle set, and confirm that the saddle has the Cantor-like fractal structure consistent with a chaotic saddle generated by horseshoe-type dynamics.

    2009-08-01

    Stable colonization of the Gaspe Peninsula by Europeans started in the middle of the 18th century at the time of the British conquest of New France. The earliest settlers were Acadians, escaping British deportation policies, followed by Loyalists from the US, who preferred to remain under British rule after the Declaration of Independence. In the 19th century, the developing fishing industry attracted French Canadians from the St. Lawrence Valley and newcomers from Europe including Channel Islanders from Jersey and Guernsey. We analyzed parental lineages of the self-declared descendants of these four groups of settlers by mtDNA D-loop sequencing and Y-chromosome genotyping and compared them with French, British, and Irish samples. Their representation in terms of haplotype frequency classes reveals different signatures of founder effects, such as a loss of rare haplotypes, modification of intermediate frequency haplotypes, reduction in genetic diversity (seen in Acadians), but also enrichment by admixture. Parental lineages correlate with group identity. Descendants of early settlers, Acadians and Loyalists, preserved their identity more than those of French Canadian and Channel Islander "latecomers." Although overall genetic diversity among Gaspesians is comparable with their European source populations, F(ST) analysis indicated their greater differentiation. Distinct settlement history, a limited number of founders and relative genetic isolation contributed to the regionalization of the Quebec gene pool that appears less homogenous than usually anticipated.

    Full Text Available This study measured changes in forest composition that have occurred since the preindustrial era along the toposequence of the Gatineau River Valley, Quebec, Canada (5650 km2, based on survey records prior to colonization (1804–1864 and recent forest inventories (1982–2006. Changes in forest cover composition over time were found to be specific to toposequence position. Maple and red oak are now more frequent on upper toposequence positions (+26%, +21%, respectively, whereas yellow birch, eastern hemlock, and American beech declined markedly (−34% to −17%. Poplar is more frequent throughout the landscape, but particularly on mid-toposequence positions (+40%. In contrast, white pine, frequent on all toposequence positions in the preindustrial forest, is now confined to shallow and coarse-textured soils (−20%. The preindustrial forest types of the study area were mostly dominated by maple, yellow birch, and beech, with strong components of white pine, hemlock, and eastern white cedar, either as dominant or codominant species. In a context of ongoing anthropogenic disturbances and environmental changes, it is probably not possible to restore many of these types, except where targeted silvicultural interventions could increase the presence of certain species. The new forest types observed should be managed to ensure continuity of vital ecosystem services and functions as disturbance regimes evolve.

    Full Text Available In order to better constrain the utility of multispectral datasets in the characterization of surface materials, Landsat Thematic Mapper (TM data were evaluated in the discrimination of geological classes in the Cape Smith Belt of Quebec, a greenstone belt that hosts Early Proterozoic units including those of the Purtuniq ophiolite. Ground-based measurements collected for the study area highlight the importance of chemical alteration in controlling the reflectance properties of key geological classes. The spatial distribution of exposed lithologies in the study area was determined through (1 image classification using a feedforward backpropagation neural network classifier; and (2 generation of fraction images for spectral end members using a linear unmixing algorithm and ground reflectance data. Despite some shortcomings, the database of surface cover generated by the neural network classifier is a useful representation of the spatial distribution of exposed geological materials in the study area, with an overall agreement with ground truth of 87.7%. In contrast, the fraction images generated through unmixing are poor representations of ground truth for several key lithological classes. These results underscore both the considerable utility and marked limitations of Landsat TM data in the mapping of igneous and metamorphic lithologies.

    Recently, there has been increasing interest in the values of occupational therapy and the values held by occupational therapists. A wide range of values has been reported in the literature. Furthermore, despite the fact that values are an important part of professional identity, empirical studies have demonstrated that several occupational therapists possess an ambiguous professional identity. This study was undertaken to explore the values of Canadian occupational therapists, specifically French-speaking occupational therapists in Quebec. Semi-structured interviews were conducted with 26 occupational therapists. Their narratives were subject to hermeneutic analysis, a method of textual analysis common in philosophical research. A total of 16 values were identified in the discourses of the occupational therapists interviewed: autonomy; human dignity; occupational participation; social justice and equity; professionalism; holism; partnership, environment, or ecological approach; quality of life; solicitude; honesty; integrity; health; creativity; professional autonomy; effectiveness; and spirituality. The results of this study are, in general, consistent with those reported in the few other empirical studies that have documented the values perceptions of occupational therapists. Finally, the explanation of the values of occupational therapists may reinforce their professional identity and favour best, or at least desirable, professional practices related to ethics and culture.

    Full Text Available Abstract Background In Canada, targeted vaccination of at risk groups for hepatitis A (HA is done since the mid 1990s resulting in declining incidence. This study estimated the year and age specific hospitalization rates and distribution of risk factors for HA in Quebec, Canada, between 1990 and 2003. Methods Records of patients hospitalized with HA-related diagnostic codes were retrieved from the provincial database. Hospital charts of all deceased cases and a random sample of all other records were reviewed. Results From 1503 hospitalization records, 573 charts were reviewed including 49 (91% of the 54 deceased patients. Confirmed acute HA was present in 79% of records where HA was the primary diagnosis, and in 3%–8% of records where HA was a secondary diagnosis. From the total estimated number of hospitalizations, 96% had HA as the primary diagnosis. The hospitalization rate decreased from 1.06 per 100 000 person-years between 1990 and 1997 to 0.36 between 1998 and 2003. During the study period, 54% HA hospitalizations were in 20–39 year-olds. The overall case fatality ratio among hospitalized patients was 1.4%, increasing from 0.4% in those Conclusion HA hospitalization rates have been low since 1998 but the cause of this is unclear given the cyclical pattern of HA. Travel to endemic countries remains the most important risk factor and improved control of HA will require better strategies to vaccinate travelers.

    Increasing longevity for Inuit living in Nunavik, northern Quebec, has resulted in heightened rates of cancers and chronic diseases necessitating complex treatments. Consequently, end-of-life (EOL) care, once the domain of Inuit families and communities, has come to include professionalized healthcare providers with varying degrees of awareness of factors to consider in providing care to Inuit populations. To better understand the factors shaping EOL care in Nunavik to support the development of a sustainable model of care. Using focused ethnography, we conducted participant observations and informal and semistructured interviews with 103 participants (community members, healthcare practitioners, and administrators) across Nunavik and in Montreal, the affiliated tertiary care center. Data domains included the following: care trajectories; patient and family experiences receiving and providing EOL care; local and urban resources and challenges; and ways forward. Sociocultural, historical, and geographic factors shape EOL care in Nunavik, presenting a complex set of challenges for Inuit patients, families, and healthcare providers. A sustainable model of EOL care requires building on shared initiatives, capitalizing on the existing strengths in communities, and attending to the multiple bereavement needs in the region. Building a sustainable model of EOL care requires respectful collaboration among governing structures, healthcare institutions, and community members. It must centrally value local knowledge and initiatives. To ensure Inuit families and patients are supported throughout the dying process, future initiatives must centrally include local stakeholders in both the design and evaluation of any changes to the current healthcare system.

    In order to describe and compare the post-fire succession patterns of the two ecological regions (mixed wood and coniferous ecoregions) of northwestern Quebec, 260 forest stands were sampled with the point-centred plot method. The mixed-wood ecological region belongs to the Abies balsamea-Betula papyrifera bioclimatic domain whereas the coniferous ecological region belongs to the Picea mariana-moss bioclimatic domain. In each plot, tree composition was described, surficial deposits and drainage were recorded, and fire history was reconstructed using standard dendro-ecological methods. Ordination techniques (Correspondence Analysis and Canonical Correspondence Analysis) were used to describe the successional patterns of forest vegetation and to correlate them with the explanatory variables. The results showed the importance of surficial deposits, the time since fire and the ecoregion in explaining the variation of stand composition. Abies balsamea tends to increase in importance with an increase in time since fire, and this trend is more pronounced in the mixed-wood region. Even when controlling both for surficial deposits and time since fire, differences in successional trends were observed between the two ecoregions. As all the species are present in both ecoregions and as they are all observed further north, our results suggest that both the landscape configuration and fire regime parameters such as fire size and fire intensity are important factors involved in these differences.

    The 2 MW-class, DFIG-type wind turbine generator of REpower Systems constitutes a major portion of the wind power installations in Quebec. In collaboration with S and C Electric, a reactive power compensation and control strategy was developed to satisfy the interconnection requirements addressing reactive power and voltage control This paper demonstrates the proposed solution, which consists of local voltage control at the wind turbines, wind turbine reactive power coordination through the REpower Power Management Unit, substation based inverters, and the S and C DSTATCOM master plant-level control at the point of connection. Through time-domain simulations, the potential dynamic performance of the wind power plant is demonstrated under normal and faulted grid conditions, considering all system elements. The results show that the response of the wind plant to system voltage variations is fast, robust, and optimized with respect to the utilization of reactive power resources. The automatic voltage regulation system is capable of maintaining the voltage at the point of connection during normal operating conditions. Under fault conditions, extra reactive current is transiently released to the grid, thus providing indispensable support to the system voltage. (orig.)

    Full Text Available This article presents findings of a larger SHHRC-funded study (1998-2002 on competencies expected of and exhibited by educational and social professionals working with young children from socioeconomically disadvantaged environments. After describing the context of socioeducational interventions in early childhood education in Quebec, the authors present the duality and the potential complementarity of the values underlying this intervention by comparing the kindergarten classroom with day-care environments for children aged 4 and 5. Then, the authors present the findings of a survey based on a random sample of parents of young Quebecois children enrolled in or having attended day-care centers or kindergarten classrooms. The article highlights the differences in parents’ expectations according to the types of pre school environment and according to socioeconomic levels. These expectations are compared to the purposes of each environment as defined by their respective curriculum articulated in official policy. Finally, the issues resulting from the debate on the educational or non-educational nature of pre-school education are examined in light of the needs of society as reflected by Quebecois parents.

    Sediments from lakes near Rouyn-Noranda, Quebec, contain elevated concentrations of several metals, including Cd, Cu, Pb and Zn. Amphipods, fingernail clams, mayflies and tanytarsid midges were absent, and sediment toxicity was observed in chronic tests with Hyalella in sediments from Lac Dufault, the lake closest to Rouyn-Noranda. Bioaccumulation by Hyalella demonstrated elevated bioavailability of Cd, Co, Cr, Pb and Tl, but only Cd was accumulated to levels close to the toxic threshold. Copper, which is regulated by Hyalella, was not elevated in these amphipods, but it was elevated in overlying water in the toxicity tests. Toxic effects in Lac Dufault sediments are probably caused primarily by Cd, at least in amphipods, with a possible minor contribution from Cu. An integrated assessment, including sediment chemistry, benthic community composition, sediment toxicity, metal bioaccumulation in benthos, and comparison of bioaccumulation and/or overlying water concentrations with threshold effect concentrations, provides the best indication of effects and their cause. - Metal bioaccumulation and metals in overlying water during toxicity tests help identify the cause of sediment toxicity and reduced benthic biodiversity.

    In Quebec, several primary care physicians have made the transition to the advanced access model to address the crisis of limited access to primary care. The objectives are to describe the implementation of the advanced access model, as perceived by the first family physicians; to analyze the factors influencing the implementation of its principles; and to document the physicians' perceptions of its effects on their practice, colleagues and patients. Qualitative methods were used to explore, through semi-structured interviews, the experiences of 21 family physicians who had made the transition to advanced access. Of the 21 physicians, 16 succeeded in adopting all five advanced access principles to varying degrees. Core implementation issues revolved around the dynamics of collaboration between physicians, nurses and other colleagues. Secretaries' functions, in particular, had to be expanded. Facilitating factors were mainly related to the physicians' leadership and the professional resources available in the organizations. Impediments related to resource availability and team functioning were also encountered. This is the first exploratory study to examine the factors influencing the adoption of the advanced access model conducted with early-adopter family physicians. The lessons drawn will inform discussions on scaling up to other settings experiencing the same problems. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

    As social elements of our environment, mass media are regarded as determinants of individual and population beliefs, social norms and habits. Since it is recognized that they influence population health, this study aims to obtain a better portrait of Quebec media content regarding physical activity and nutrition messages on a public health level. First, we analyzed the content of fictional television shows (n = 1 3) and advertisements broadcast during those shows (n = 68). Second, we reviewed the content of La Presse newspaper and of French television Société Radio-Canada from 1986 to 2005 with regard to physical activity and nutrition messages. Our results indicate a difference between how men and women are portrayed on French television, with women more often being shown as underweight and men as at or above healthy body weight. The results also show that during the 20-year period of the reviewed content, there were fewer messages about physical activity than about nutrition. To be successful in their goal of improving population health, mass media should address both subjects together in their messages.

    Pre-Silurian bedrock units played key roles in the early Paleozoic history of the Maine-Quebec Appalachians. These units represent peri-Laurentian material whose collision with the craton deformed the Neoproteozoic passive margin and initiated the Appalachian mountain-building cycle. We present new field, petrological, geochronological, and geochemical data to support the following interpretations related to these units. (1) The Boil Mountain Complex and Jim Pond Formation do not represent part of a coherent ophiolite. (2) Gabbro and tonalite of the Boil Mountain Complex intruded the Chain Lakes massif at ca. 477 Ma. (3) The Skinner pluton, an arc-related granodiorite, intruded the Chain Lakes massif at ca. 472 Ma. (4) The Attean pluton, with a reconfirmed age of ca. 443 Ma, is unrelated to Early Ordovician orogenesis. (5) The most likely timing for the juxtaposition of the Jim Pond Formation and the Boil Mountain Complex was during regional Devonian deformation. These interpretations suggest that the Boundary Mountains were once part of a series of arcs extending at least from central New England through Newfoundland. ?? 2006 NRC Canada.

  17. Integration of OHS into Risk Management in an Open-Pit Mining Project in Quebec (Canada

    Full Text Available Despite undeniable progress, the mining industry remains the scene of serious accidents revealing disregard for occupational health and safety (OHS and leaving open the debate regarding the safety of its employees. The San José mine last collapse near Copiapó, Chile on 5 August 2010 and the 69-day rescue operation that followed in order to save 33 miners trapped underground show the serious consequences of neglecting worker health and safety. The aim of this study was to validate a new approach to integrating OHS into risk management in the context of a new open-pit mining project in Quebec, based on analysis of incident and accident reports, semi-structured interviews, questionnaires and collaborative field observations. We propose a new concept, called hazard concentration, based on the number of hazards and their influence. This concept represents the weighted fraction of each category of hazards related to an undesirable event. The weight of each category of hazards is calculated by AHP, a multicriteria method. The proposed approach included the creation of an OHS database for facilitating expert risk management. Reinforcing effects between hazard categories were identified and all potential risks were prioritized. The results provided the company with a rational basis for choosing a suitable accident prevention strategy for its operational activities.

    Prophylactic mastectomy is an effective, although controversial strategy to reduce the risk of breast cancer in women carrying a BRCA1/2 mutation. A multidisciplinary pre- and post-operative clinical management is recommended for women who consider or undergo this surgery, because of its radical and irreversible nature as well as its possible impact on quality of life. This study aims to report on the experience of patients having undergone prophylactic mastectomy within a medical setting offering such a clinical management. A retrospective qualitative study was conducted with patients having had a prophylactic mastectomy between 2002 and 2006 at the centre des maladies du sein Deschênes-Fabia (CMSDF) in Quebec City. Fifteen women were interviewed and the narratives were analyzed using thematic content analysis method. The participants generally appreciated the multidisciplinary approach that was used at the CMSDF and believed it was necessary. Improvements were suggested regarding information and post-surgical medical follow-up, some of which are now implemented. The study results confirm the utility and the acceptability of a multidisciplinary clinical follow-up for women who undergo prophylactic mastectomy.

    The Lac St-Jean anorthosite massif underlies an area of over 20,000 km2 and has been emplaced into migmatitic gneisses of the central granulite terrain of the Grenville Province of the Canadian shield. Field data and petrography in an area straddling the anorthosite-gneiss contact, close to Chicoutimi (Quebec) permits an outline of its tecto-magmatic evolution. Depositional magmatic textures in the massif reveals that it crystallized from a magma in a relatively calm tectonic environment. The absence of fusion in pelitic gneisses at the contact proves that the crystallization did not take place at the level presently exposed. The parallelism of subvertical foliation in the enveloping gneisses and the anorthosite indicates that both were deformed together. It is suggested that the deformation results from a diapiric ascent of the anorthosite massif after its consolidation at depth. The depth of consolidation of the anorthosite is estimated at ˜ 25 30 km from subsolidus reaction between plagioclase and olivine. The diapiric ascent is further substantiated by the fact that three sets of mafic dykes of different ages, intrusive into the anorthosite, have a mineralogy which indicates successively decreasing P, T conditions of emplacement from granulite fades to amphibolite facies. An evolution of the basement gneisses and the anorthosite is proposed as a working hypothesis; it relies on the fact that metabasite dyke swarms in the basement gneisses represent a period of major crustal extension and could be used as a stratigraphic subdivision of the Grenville Province.

    2016-09-01

    An integrated seismo- and chronostratigraphic investigation at Lac Dasserat, northwestern Quebec, identified 74 separate failures within eight event horizons. Horizons E and B, and H and G have strong or moderately-strong multi-landslide signatures, respectively, composed of 11-23 failures, while horizons F, D, C, and A have minor landslide signatures consisting of a single or pair of deposit(s). Cores collected at six sites recovered glacial Lake Ojibway varve deposits that are interbedded with the event horizons. The correlation of the varves to the regional Timiskaming varve series allowed varve ages or ranges of varve ages to be determined for the event horizons. Horizons H, G, E, and B are interpreted to be evidence of paleoearthquakes with differing levels of interpretative confidence, based on the relative strength of the multi-landslide signatures, the correlation to other disturbed deposits of similar age in the region, and the lack or possibility of alternative aseismic mechanisms. The four interpreted paleoearthquakes occurred between 9770 ± 200 and 8470 ± 200 cal yr BP, when glacial Lake Ojibway was impounded behind the Laurentide Ice Sheet during deglaciation. They probably represent an elevated period of seismicity at deglaciation that was driven by crustal unloading.

    A 60 year-old woman with a scalp epithelioma underwent radiotherapy, the dose being 57 Gray. A first epileptic seizure occurred twenty months later. Neurological examination revealed signs of left hemisphere involvement. ..gamma..EG, angiography, CT scans, demonstrated a pseudotumoral avascular process. On account of the localisation, the patient being right-handed, no surgical procedure was performed. In spite of corticotherapy and anticonvulsive treatment, seizures recurred and neurological signs slowly progressed. The patient died, 22 months after the first seizure, of an associated disseminated carcinoma with cachexia. Neuropathological examination showed a massive lesion presenting all the features of delayed radionecrosis in the left hemisphere: situated mainly in the white matter; numerous vascular abnormalities; wide-spread demyelination; disappearance of oligoglial cells. The Authors recall the clinical and anatomical aspects of this condition for which the only successful treatment is surgical removal when location and size of the lesion permit. Finally, the mechanisms which have been proposed to explain this delayed cerebral radionecrosis are discussed.

    A large body of literature on diminished ejaculatory disorders has been generated without the use of a clear diagnostic definition. Many studies have not distinguished between the orgasm and ejaculation disorders leading to doubtful results. Delayed ejaculation (DE) is one of the diminished ejaculatory disorders, which range from varying delays in ejaculatory latency to a complete inability to ejaculate. The present review is aimed at providing a comprehensive overview of the current knowledge on the definition and epidemiology of diminished ejaculatory disorders. We focus on the acquired diseases, such as benign prostatic hyperplasia (BPH) and specific drug regimens that may cause an iatrogenic form of ejaculatory disorder. In addition, the impact of aging is discussed since the prevalence of DE appears to be moderately but positively related to age. Finally, we also focus on the importance of the hormonal milieu on male ejaculation. To date, evidence on the endocrine control of ejaculation is derived from small clinical trials, but the evidence suggests that hormones modulate the ejaculatory process by altering its overall latency.

    This paper generalizes the stability test method via integral estimation for integer-order neutral time-delay systems to neutral fractional-delay systems. The key step in stability test is the calculation of the number of unstable characteristic roots that is described by a definite integral over an interval from zero to a sufficient large upper limit. Algorithms for correctly estimating the upper limits of the integral are given in two concise ways, parameter dependent or independent. A special feature of the proposed method is that it judges the stability of fractional-delay systems simply by using rough integral estimation. Meanwhile, the paper shows that for some neutral fractional-delay systems, the stability is extremely sensitive to the change of time delays. Examples are given for demonstrating the proposed method as well as the delay sensitivity.

    The French-Canadian population in the Saguenay-Lac St. Jean region of northeastern Quebec has an elevated frequency of cystic fibrosis (CF). The average incidence of cystic fibrosis was 1 in 891 births and the prevalence of CF carriers was estimated to be 1 in 15. We tested for 10 mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene in 133 French-Canadian CF families from Quebec. Ninety-one families were from the Saguenay-Lac St. Jean region and 42 families were referred from other regions of Quebec. We detected the CFTR mutation in 93 and 92% of the CF chromosomes in the Saguenay-Lac St. Jean and the major-urban Quebec families, respectively. The two groups of French-Canadian families were significantly different for the proportions of CFTR mutations. The three most common mutations in the Saguenay-Lac St. Jean families were delta F508 (58%), 621 + 1G----T (23%), and A455E (8%); and in the major-urban Quebec families were delta F508 (71%), 711 + 1G----T (9%), and 621 + 1G----T (5%). These results provide evidence for the role of founder effect in the elevated incidence of cystic fibrosis in the Saguenay-Lac St. Jean population.

    Highlights: > Delay and anticipation in coupling function varies with system dynamics. > Delay or anticipation of the synchronized state is independent of system delay. > Stability analysis developed is quite general. > We demonstrate enhanced security in communication. > Generalized synchronization possible over a wide range of parameter mismatch. - Abstract: We present a mechanism for synchronizing time delay systems using one way coupling with a variable delay in coupling that is reset at finite intervals. We present the analysis of the error dynamics that helps to isolate regions of stability of the synchronized state in the parameter space of interest for single and multiple delays. We supplement this by numerical simulations in a standard time delay system like Mackey Glass system. This method has the advantage that it can be adjusted to be delay or anticipatory in synchronization with a time which is independent of the system delay. We demonstrate the use of this method in communication using the bi channel scheme. We show that since the synchronizing channel carries information from transmitter only at intervals of reset time, it is not susceptible to an easy reconstruction.

  7. Small delay approximation of stochastic delay differential equations

    Delay differential equations evolve in an infinite-dimensional phase space. In this paper, we consider the effect of external fluctuations (noise) on delay differential equations involving one variable, thus leading to univariate stochastic delay differential equations (SDDE's). For small delays, a univariate nondelayed stochastic differential equation approximating such a SDDE is presented. Another approximation, complementary to the first, is also obtained using an average of the SDDE's drift term over the delayed dynamical variable, which defines a conditional average drift. This second approximation is characterized by the fact that the diffusion term is identical to that of the original SDDE. For small delays, our approach yields a steady-state probability density and a conditional average drift which are in close agreement with numerical simulations of the original SDDE. We illustrate this scheme with the delayed linear Langevin equation and a stochastic version of the delayed logistic equation. The technique can be used with any type of noise, and is easily generalized to multiple delays.

    This brief presents emerging and promising communication methods for network reliability via delay tolerant networks (DTNs). Different from traditional networks, DTNs possess unique features, such as long latency and unstable network topology. As a result, DTNs can be widely applied to critical applications, such as space communications, disaster rescue, and battlefield communications. The brief provides a complete investigation of DTNs and their current applications, from an overview to the latest development in the area. The core issue of data forward in DTNs is tackled, including the importance of social characteristics, which is an essential feature if the mobile devices are used for human communication. Security and privacy issues in DTNs are discussed, and future work is also discussed.

    Full Text Available A neovesicocutaneous fistula is a rare complication after orthotopic bladder reconstruction, particularly in the late postoperative period. We report the case of a 59-year-old man who had undergone ileal neobladder construction 17 months previously. He presented with urinary retention concomitant with urinary tract infection due to a neovesicourethral anastomotic stricture. After a combination of transurethral catheter drainage and broad-spectrum antibiotic therapy for 3 weeks, the fistulous tract completely closed. Therefore, conservative treatment may be regarded as a valid option for a delayed neovesicocutaneous fistula.

Sufficient condition for stability in probability of the equilibrium point of the dynamic model with aftereffect and stochastic perturbations is obtained via Kolmanovskii and Shaikhet general method of Lyapunov functionals construction. We conclude that alcohol consumption in Spain will be constant (with stability in time with around 36.47% of nonconsumers, 62.94% of nonrisk consumers, and 0.59% of risk consumers. This approach allows us to emphasize the possibilities of the dynamical models in order to study human behaviour.

  11. Fixed points and controllability in delay systems

    Directory of Open Access Journals (Sweden)

    2006-01-01

    Full Text Available Schaefer's fixed point theorem is used to study the controllability in an infinite delay system x ′ ( t = G ( t , x t + ( B u ( t . A compact map or homotopy is constructed enabling us to show that if there is an a priori bound on all possible solutions of the companion control system x ′ ( t = λ [ G ( t , x t + ( B u ( t ] , 0 < λ < 1 , then there exists a solution for λ = 1 . The a priori bound is established by means of a Liapunov functional or applying an integral inequality. Applications to integral control systems are given to illustrate the approach.

    We study the gravitational time delay in ray propagation due to rotating masses in the linear approximation of general relativity. Simple expressions are given for the gravitomagnetic time delay that occurs when rays of radiation cross a slowly rotating shell and propagate in the field of a distant rotating source. Moreover, we calculate the local gravitational time delay in the Goedel universe. The observational consequences of these results in the case of weak gravitational lensing are disc...

    This study identifies factors that predict delayed divorce in the US. The findings show that factors which influence marital stability in general also correlate with delayed divorce in the same direction. Wife's age at marriage, age of the youngest child, wife's religion, region of residence, and metropolitan residence have substantial effects of delayed divorce, but the effects of race, parental divorce, premarital pregnancy, and socioeconomic status are small.

    When combining data from various sensors it is vital to acknowledge possible measurement delays. Furthermore, the sensor fusion algorithm, often a Kalman filter, should be modified in order to handle the delay. The paper examines different possibilities for handling delays and applies a new techn...... technique to a sensor fusion system for estimating the location of an autonomous guided vehicle. The system fuses encoder and vision measurements in an extended Kalman filter. Results from experiments in a real environment are reported...

    Full Text Available Este artigo traz uma análise comparativa Canadá/Quebec de interrelações: de um lado, três modelos de regulação da educação (a burocracia estatal, a profissão e o mercado; e, de outro, a autonomia profissional dos professores. A noção de autonomia profissional dos professores, tal como é veiculada pelas associações profissionais e sindicatos canadenses e quebequenses, permite analisar a evolução desses modos de regulação. Adotando um ponto de vista neo-institucionalista, o artigo mostra que a autonomia profissional reivindicada ou defendida pelos professores como por suas associações sindicais repousa mais sobre as atividades percebidas como centrais por esses atores que sobre aquelas ditas periféricas. Isto permite compreender a força da reação no restante do Canadá contra a centralização do currículo e a padronização da avaliação da aprendizagem e a relativa acomodação dos professores quebequenses à participação nos conselhos escolares e na participação dos pais. Nesses dois contextos, entretanto, constatamos uma resistência à reorganização do trabalho dos professores.The paper deals with the relationships between models of regulation (bureaucratic, professionnal and market of education and teacher autonomy. As espoused by professional and labour associations of Canada and Quebec, teacher autonomy is used to disclose the evolution of models of educational regulation. Adopting a neo-institutionalist point of view, the paper argues that teacher autonomy, as promoted by canadian teacher unions, refers to activities considered central of teachers' work, as opposed to peripheral activities. This distinction helps understand why in Canada a strong reaction against curriculum centralization and standardization of evaluation has been observed, whereas Quebec teachers' unions seem to accommodate themselves with an increase in parental power.

    Full Text Available Uniform finite difference methods are constructed via nonstandard finite difference methods for the numerical solution of singularly perturbed quasilinear initial value problem for delay differential equations. A numerical method is constructed for this problem which involves the appropriate Bakhvalov meshes on each time subinterval. The method is shown to be uniformly convergent with respect to the perturbation parameter. A numerical example is solved using the presented method, and the computed result is compared with exact solution of the problem.

    Full Text Available Biological carbon sequestration by forest ecosystems plays an important role in the net balance of greenhouse gases, acting as a carbon sink for anthropogenic CO2 emissions. Nevertheless, relatively little is known about the abiotic environmental factors (including climate that control carbon storage in temperate and boreal forests and consequently, about their potential response to climate changes. From a set of more than 94,000 forest inventory plots and a large set of spatial data on forest attributes interpreted from aerial photographs, we constructed a fine-resolution map (∼375 m of the current carbon stock in aboveground live biomass in the 435,000 km2 of managed forests in Quebec, Canada. Our analysis resulted in an area-weighted average aboveground carbon stock for productive forestland of 37.6 Mg ha−1, which is lower than commonly reported values for similar environment. Models capable of predicting the influence of mean annual temperature, annual precipitation, and soil physical environment on maximum stand-level aboveground carbon stock (MSAC were developed. These models were then used to project the future MSAC in response to climate change. Our results indicate that the MSAC was significantly related to both mean annual temperature and precipitation, or to the interaction of these variables, and suggest that Quebec’s managed forests MSAC may increase by 20% by 2041–2070 in response to climate change. Along with changes in climate, the natural disturbance regime and forest management practices will nevertheless largely drive future carbon stock at the landscape scale. Overall, our results allow accurate accounting of carbon stock in aboveground live tree biomass of Quebec’s forests, and provide a better understanding of possible feedbacks between climate change and carbon storage in temperate and boreal forests.

    Background: Continuous glucose monitoring (CGM) is a powerful tool to support the optimization of glucose control of patients with diabetes. However, CGM systems measure glucose in interstitial fluid but not in blood. Rapid changes in one compartment are not accompanied by similar changes in the other, but follow with some delay. Such time delays hamper detection of, for example, hypoglycemic events. Our aim is to discuss the causes and extent of time delays and approaches to compensate for these. Methods: CGM data were obtained in a clinical study with 37 patients with a prototype glucose sensor. The study was divided into 5 phases over 2 years. In all, 8 patients participated in 2 phases separated by 8 months. A total number of 108 CGM data sets including raw signals were used for data analysis and were processed by statistical methods to obtain estimates of the time delay. Results: Overall mean (SD) time delay of the raw signals with respect to blood glucose was 9.5 (3.7) min, median was 9 min (interquartile range 4 min). Analysis of time delays observed in the same patients separated by 8 months suggests a patient dependent delay. No significant correlation was observed between delay and anamnestic or anthropometric data. The use of a prediction algorithm reduced the delay by 4 minutes on average. Conclusions: Prediction algorithms should be used to provide real-time CGM readings more consistent with simultaneous measurements by SMBG. Patient specificity may play an important role in improving prediction quality. PMID:26243773

    Many different types of vocational programs (services) exist to help people with severe mental disorders (e.g., schizophrenia) integrate the regular labor market: sheltered workshops, social enterprises, and supported employment programs to name a few. Each type of vocational services has its specificities: on one hand, some of them are following the "train and place" approach. For example, sheltered workshops offer to people with a severe mental illness a training during a long period of, with a small proportion obtaining competitive employment. On the other hand, other programs adopt the "place and train" philosophy, such as supported employment programs, in which employment specialists help people obtain a competitive job as fast as possible with no requested training. This article presents two original vocational services, the Messidor's sheltered workshops in France and the Accès-Cible SMT supported employment program in Quebec, following an "hybrid" approach including both philosophies "place and train" and "train and place". More particularly, they are both aiming at competitive employment on the regular labor market for people with a severe mental illness, with a different length of training. Messidor consists of a sheltered workplace for people with a severe mental illness in France, using this time of transition in the workshops as a tool to obtain a competitive job. Thanks to three key factors, Messidor succeeds in placing many of their workers in the French regular labor market: (1) Workers with severe mental disorders work on tasks and workplaces similar to those in regular labor market; (2) Messidor's managers have small teams (5-7 persons) that offer a nearby and personalized management to workers; (3) Each worker is followed by a Messidor's employment counsellor, to build together a working plan and put in place work strategies to obtain a competitive job. This "double management" seems to be a key ingredient of this support as it promotes some

    The Quebec Patient Smart Card Project is a Provincial Government initiative under the responsibility of the Rgie de l'assurance-maladie du Québec (Quebec Health Insurance Board). Development, implementation, and assessment duties were assigned to a team from Université Laval, which in turn joined a group from the Direction de la santé publique du Bas-St-Laurent in Rimouski, where the experiment is taking place. The pilot project seeks to evaluate the use and acceptance of a microprocessor card as a way to improve the exchange of clinical information between card users and various health professionals. The card can be best described as a résumé containing information pertinent to an individual's health history. It is not a complete medical file; rather, it is a summary to be used as a starting point for a discussion between health professionals and patients. The target population is composed of persons 60 years and over, pregnant women, infants under 18 months, and the residents of a small town located in the target area, St-Fabien, regardless of age. The health professionals involved are general practitioners, specialists, pharmacists, nurses, and ambulance personnel. Participation in the project is on a voluntary basis. Each health care provider participating in the project has a personal identification number (PIN) and must use both an access card and a user card to access information. This prevents unauthorized access to a patient's card and allows the staff to sign and date information entered onto the patient card. To test the microprocessor card, we developed software based on a problem-oriented approach integrating diagnosis, investigations, treatments, and referrals. This software is not an expert system that constrains the clinician to a particular decisional algorithm. Instead, the software supports the physician in decision making. The software was developed with a graphical interface (Windows 3.1) to maximize its user friendliness. A version of the

    Full Text Available Abstract Background Abundant literature supports the beneficial effects of physical activity for improving health of people with chronic diseases. The relationship between multimorbidity and physical activity levels, however, has been little evaluated. The purpose of the current exploratory study was to examine the relationship between a multimorbidity and physical activity levels, and b long-term limitations on activity, self-rated general health, psychological distress, and physical activity levels for each sex in adults, after age, education, income, and employment factors were controlled for. Methods Data from the Quebec Health Survey 1998 were used. The sample included 16,782 adults 18–69 yr of age. Independent variables were multimorbidity, long-term limitations on activity, self-rated general health, and psychological distress. The dependent variable was physical activity levels. Links between the independent and dependent variables were assessed separately for men and women with multinomial regressions while accounting for the survey sampling design and household clustering. Results About 46% of the participants were men. Multimorbidity was not associated with physical activity levels for either men or women. Men and women with long-term limitations on activity and with poor-to-average self-rated general health were less likely to be physically active. No relationship between psychological distress and physical activity was found for men. Women with high levels of psychological distress were less likely to be physically active. Conclusion Multimorbidity was not associated with physical activity levels in either sex, when age, education, income, and employment factors were controlled for. Long-term limitations on activity and poor-to-average self-rated general health seem related to a reduction in physical activity levels for both sexes, whereas psychological distress was associated with a reduction in physical activity levels only

    Mineral soil horizons (Ae, Bhf1, Bhf2, Bf, BC and C) were carefully collected from two podzolic soil profiles in the Lake Clair watershed (Quebec) in order to assess anthropogenic trace metal accumulation. Petrographic and selective analyses were performed to establish the soil mineralogy and properties. Furthermore, a complete sequential extraction procedure has been applied to help understanding the complex chemical speciation of Pb in forest soils. Chemical speciation of Pb showed a strong vertical gradient: 85% of this metal is mainly partitioned in refractory minerals in the C-horizon whereas in the upper Bhf1 and Ae-horizons, less than 50% of Pb is associated with this fraction. In the Ae-horizon, for example, 35%, 30% and 12% of total Pb, respectively, is associated with the exchangeable, labile organic matter and amorphous Fe-Mn oxides fractions. The distribution of Pb and Cr in the studied forest soils mainly reflects progressive contamination of the watershed by anthropogenic atmospheric sources. The anthropogenic source is indicated by elevated Cr and Pb concentrations in the topsoil (Bhf and Ae) horizons and by strong negative correlation between {sup 206}Pb/{sup 207}Pb ratios and total Pb concentrations. According to these isotopic values, penetration of anthropogenic Pb does not exceed 10 cm in both soil profiles. Below this depth, both Pb concentrations and isotopic ratios remain nearly constant and similar to values observed in pre-anthropogenic sediments from Lake Clair. These values are interpreted as the natural geochemical backgrounds of the watershed. Based on that behaviour, calculated anthropogenic Pb net inputs amounted to between 1.24 and 1.8 g/m{sup 2}.

  6. Effects of insecticide use on breeding birds in Christmas tree plantations in Quebec.

    : This research, which was carried out in the spring of 1989 and 1990 in seven balsam fir (Abies balsamea) plantations in southeastern Quebec, examines potential deleterious effects of three insecticides (i.e. dimethoate, diazinon and insecticidal soap) on breeding American Robins (Turdus migratorius) (n=87 nests) and Song Sparrows (Melospizsa melodia) (n=41 nests). Through analyses of blood serum cholinesterases (AChE and BChE) activity both prior to and the second day following applications of the two organophosphorus insecticides, we showed that adult American Robins, Song Sparrows and Chipping Sparrows (Spizella passerina) breeding in the treated plantations were exposed to diazinon and dimethoate (p<0.05). Signs of exposure to diazinon (p<0.05) were also found in young American Robins. However, despite sharp reductions in blood ChE (and, in some cases, marked inhibition confirmed by 2-PAM reactivation), no cases of adult mortality were recorded following the treatments. Cases of complete or partial mortality were recorded in American Robin and Song Sparrow nests, even among control birds (non-exposed birds). No mortality was recorded for broods exposed to the insecticidal soap. Abandonment of nests and egg infertility were ruled out as possible causes of mortality. The cases of total mortality observed in American Robin and Song Sparrow broods exposed to dimethoate were similar to those recorded for control nests (18 and 25% compared to 14 and 21%, respectively). However, among American Robin and Song Sparrow nestlings exposed to diazinon, essentially twice as many cases of total mortality (31 and 38%, respectively) were recorded as for the control nests. It appears that American Robin eggs are sensitive to diazinon and dimethoate, particularly when spraying is carried out early in the incubation stage. In the case of the Song Sparrow, it is mainly the nestlings that succumb after diazinon is sprayed on them or when dimethoate applications are made during the

    The increasing number of studies on the determination of natural methane in groundwater of shale gas prospection areas offers a unique opportunity for refining the quantification of natural methane emissions. Here methane emissions, computed from four potential sources, are reported for an area of ca. 16,500km(2) of the St. Lawrence Lowlands, Quebec (Canada), where Utica shales are targeted by the petroleum industry. Methane emissions can be caused by 1) groundwater degassing as a result of groundwater abstraction for domestic and municipal uses; 2) groundwater discharge along rivers; 3) migration to the surface by (macro- and micro-) diffuse seepage; 4) degassing of hydraulic fracturing fluids during first phases of drilling. Methane emissions related to groundwater discharge to rivers (2.47×10(-4) to 9.35×10(-3)Tgyr(-1)) surpass those of diffuse seepage (4.13×10(-6) to 7.14×10(-5)Tgyr(-1)) and groundwater abstraction (6.35×10(-6) to 2.49×10(-4)Tgyr(-1)). The methane emission from the degassing of flowback waters during drilling of the Utica shale over a 10- to 20-year horizon is estimated from 2.55×10(-3) to 1.62×10(-2)Tgyr(-1). These emissions are from one third to sixty-six times the methane emissions from groundwater discharge to rivers. This study shows that different methane emission sources need to be considered in environmental assessments of methane exploitation projects to better understand their impacts.

    Laberge, C

    1989-02-01

    The geographical distribution relative to place of residence of patients with myotonic dystrophy (MD) and admitted to a Quebec hospital during a five year period (1980-1984) is presented and discussed. The sample consists of 72 males and 68 females of varying ages over 10 years. Analysis of the data shows a North Shore distribution of patients in a cline from Saguenay-Lac-St-Jean, through Québec City and to Montréal. However, a low prevalence is apparent on the South Shore, east of Québec City, for which an historical and genealogical explanation are discussed. This geographic distribution favours the hypothesis of genetic homogeneity for the MD gene in the Québec population. A stronger second argument comes from genealogical studies of 10 families sampled from the Chicoutimi Muscular Dystrophy Clinic. Genealogical paths traced to ancestors who founded Charlevoix for these 10 families go back to a cluster of 25 founders, one of whom must have been the carrier of the MD gene. The probative third argument for genetic homogeneity comes from the allelic distribution of the apolipoprotein E (ApoE) gene in the Québec City, Saguenay and in families with MD. The ApoE locus is on chromosome 19 and closely linked to MD. In MD-affected individuals there is a linkage disequilibrium for the epsilon 4 allele while non-MD members of these families show allelic frequencies not differing significantly from the control population.(ABSTRACT TRUNCATED AT 250 WORDS)

    Nastev, M.; Savard, M. M.; Lapcevic, P.; Lefebvre, R.; Martel, R.

    This paper reports on the characterization of hydraulic properties of regional rock aquifers carried out within a groundwater resources assessment project in the St. Lawrence Lowlands of south-western Quebec. To understand the aquifer behavior at both the fracture level and at field scale, hydraulic investigations were carried out using various aquifer tests. The groundwater flow at the local scale is controlled mostly by the fracture system. Results of the constant-head injection tests show a weak decreasing trend of hydraulic conductivity with depth indicating that a major part of the groundwater flow occurs in the first meters of the rock sequence. At the regional scale, the equivalent porous media approach is applicable. The hydraulic conductivity measurements were correlated to the scale of the aquifer tests expressed with the investigated aquifer volume. A simple interpolation procedure for the hydraulic conductivity field was developed based on the distance between field measurements and the tested aquifer volumes. The regional distribution of the hydraulic conductivity for the major fractured aquifer units indicates that dolostone is the most permeable whereas sandstone and crystalline rocks are the least permeable units. Este artículo trata de la caracterización de las propiedades hidráulicas en acuíferos regionales rocosos, la cual se llevó a cabo dentro del proyecto de evaluación de los recursos de agua subterránea en St. Lawrence Lowlands al suroeste de Quebec. Para entender el comportamiento del acuífero tanto a nivel de fractura como a escala del campo, se ejecutaron investigaciones hidráulicas usando varias pruebas de acuífero. El flujo del agua subterránea a escala local está controlado principalmente por el sistema de fracturas. Los resultados de las pruebas de inyección con cabeza constante muestran una tendencia decreciente débil de la conductividad hidráulica con la profundidad, indicando que la mayor parte del flujo de agua

    2016-06-01

    This paper deals with the problem of linearisation of systems with constant commensurable delays by input-output injection using algebraic control tools based on the theory of non-commutative rings. Solutions for the problem of linearisation free of delays, and with delays of an observable nonlinear time-delay systems are presented based on the analysis of the input-output equation. These results are achieved by means of constructive algorithms that use the nth derivative of the output expressed in terms of the state-space variables instead of the explicit computation of the input-output representation of the system. Necessary and sufficient conditions are established in both cases by means of an invertible change of coordinates.

    2006-01-01

    Two design approaches of state feedback and output feedback tracking controllers are proposed for a class of strict feedback nonlinear time-delay systems by using backstepping technique. When the states of system cannot be observed, the time-delay state observer is designed to estimate the system states. Domination method is used to deal with nonlinear time-delay function under the assumption that the nonlinear time-delay functions of systems satisfy Lipschitz condition. The global asymptotical tracking of the references signal is achieved and the bound of all signals of the resultant closed-loop system is also guaranteed. By constructing a Lyapunov-Krasoviskii functional, the stability of the closed-loop system is proved. The feasibility of the proposed approach is illustrated by a simulation example.

    The IRSL dating of Middle Pleistocene interglacial fluvial sediments from Southern Quebec, correlated with oxygen isotopic stage 7, yields optical dates much younger than the expected geological age. Single grain IRSL measurements on alkali-feldspars, following the fadia protocol developed by Lamothe and Auclair (Earth and Planetary Science Letters, 171, 319-323, 1999), suggest that anomalous fading is the most probable cause for this severe age underestimation. The IRSL dates corrected for this anomalous fading are in better agreement with the expected ages. ?? 2000 Elsevier Science Ltd.

    Based on various databases, carbon stocks of terrestrial ecosystems in the boreal and arctic biomes of Quebec were quantified as part of an evaluation of their capacity to mitigate anthropogenic greenhouse gas (GHG) emissions and estimate their vulnerability with respect to recent climate change and land use changes. The results of this project are contributing to the establishment of the Strategy for Climate Change Adaptation as well as the 2013-2020 Climate Change Action Plan of the Quebec Ministry of Environment, which aim to adapt the Quebec society to the effects of climate change and the reduction of GHG emissions. The total carbon stock of the soils of the forest and peatland ecosystems of Quebec was quantified at 18.00 Gt C or 66.0 Gt CO2-equivalent, of which 95% corresponds to the boreal and arctic regions. The mean carbon mass per unit area (kg C m-2) of peatlands is about nine times higher than that of forests, with values of 100,0 kg C m-2 for peatlands and 10,9 kg C m-2 for forest stands. In 2013, total anthropogenic emissions in Quebec were quantified at 82.6 Mt CO2-equivalent (Environment Canada, 2015), or 1.25‰ of the total Quebec ecosystem carbon stock. The total stock thus represents the equivalent of about 800 years of anthropogenic emissions at the current rate, divided between 478 years for peatlands and 321 years for forest soils. Future GHG mitigation policies and sustainable land-use planning should be supported by scientific data on terrestrial ecosystems carbon stocks. An increase in investments in peatland, wetland and forest conservation, management and rehabilitation may contribute to limit greenhouse gas emissions. It is therefore essential, that, following the objectives of multiple international organisations, the management of terrestrial carbon stocks becomes part of the national engagement to reduce GHG emissions.

  1. On the Global Dissipativity of a Class of Cellular Neural Networks with Multipantograph Delays

    2011-01-01

    Full Text Available For the first time the global dissipativity of a class of cellular neural networks with multipantograph delays is studied. On the one hand, some delay-dependent sufficient conditions are obtained by directly constructing suitable Lyapunov functionals; on the other hand, firstly the transformation transforms the cellular neural networks with multipantograph delays into the cellular neural networks with constant delays and variable coefficients, and then constructing Lyapunov functionals, some delay-independent sufficient conditions are given. These new sufficient conditions can ensure global dissipativity together with their sets of attraction and can be applied to design global dissipative cellular neural networks with multipantograph delays and easily checked in practice by simple algebraic methods. An example is given to illustrate the correctness of the results.

    Method and apparatus are provided for generating an output pulse following a trigger pulse at a time delay interval preset with a resolution which is high relative to a low resolution available from supplied clock pulses. A first lumped constant delay (20) provides a first output signal (24) at predetermined interpolation intervals corresponding to the desired high resolution time interval. Latching circuits (26, 28) latch the high resolution data (24) to form a first synchronizing data set (60). A selected time interval has been preset to internal counters (142, 146, 154) and corrected for circuit propagation delay times having the same order of magnitude as the desired high resolution. Internal system clock pulses (32, 34) count down the counters to generate an internal pulse delayed by an interval which is functionally related to the preset time interval. A second LCD (184) corrects the internal signal with the high resolution time delay. A second internal pulse is then applied to a third LCD (74) to generate a second set of synchronizing data (76) which is complementary with the first set of synchronizing data (60) for presentation to logic circuits (64). The logic circuits (64) further delay the internal output signal (72) to obtain a proper phase relationship of an output signal (80) with the internal pulses (32, 34). The final delayed output signal (80) thereafter enables the output pulse generator (82) to produce the desired output pulse (84) at the preset time delay interval following input of the trigger pulse (10, 12).

    2017-05-07

    Based on the classic imitation dynamics (Hofbauer and Sigmund, 1998, Evolutionary Games and Population Dynamics, Cambridge University Press), the imitation dynamics with time delay is investigated, where the probability that an individual will imitate its opponent's own strategy is assumed to depend on the comparison between the past expected payoff of this individual's own strategy and the past expected payoff of its opponent's own strategy, i.e. there is a time delay effect. For the two-phenotype model, we show that if the system has an interior equilibrium and this interior equilibrium is stable when there is no time delay, then there must be a critical value of time delay such that the system tends to a stable periodic solution when the time delay is larger than the critical value. On the other hand, for three-phenotype (rock-scissors-paper) model, the numerical analysis shows that for the stable periodic solution induced by the time delay, the amplitude and the period will increase with the increase of the time delay. These results should help to understand the evolution of behavior based on the imitation dynamics with time delay. Copyright © 2017 Elsevier Ltd. All rights reserved.

    In this paper, existing damping theories are briefly reviewed. On the basis of the existing damping theories, a new kind of damping theory, i.e., the time-delay damping theory, is developed. In the time-delay damping theory, the damping force is considered to be directly proportional to the increment of displacement. The response analysis of an SDOF time-delay damping system is carried out, and the methods for obtaining the solution for a time-delay damping system in the time domain as well as the frequency domain are given. The comparison between results from different damping theories shows that the time-delay damping theory is both reasonable and convenient.

  10. Asynchronous Bounded Expected Delay Networks

    CERN Document Server

    Bakhshi, Rena; Fokkink, Wan; Pang, Jun

    2010-01-01

    The commonly used asynchronous bounded delay (ABD) network models assume a fixed bound on message delay. We propose a probabilistic network model, called asynchronous bounded expected delay (ABE) model. Instead of a strict bound, the ABE model requires only a bound on the expected message delay. While the conditions of ABD networks restrict the set of possible executions, in ABE networks all asynchronous executions are possible, but executions with extremely long delays are less probable. In contrast to ABD networks, ABE networks cannot be synchronised efficiently. At the example of an election algorithm, we show that the minimal assumptions of ABE networks are sufficient for the development of efficient algorithms. For anonymous, unidirectional ABE rings of known size N we devise a probabilistic leader election algorithm having average message and time complexity O(N).

    The problem of delay-dependent asymptotic stability criteria for neural networks with time-varying delay is investigated. A new class of Lyapunov functional is constructed to derive some new delay-dependent stability criteria.The obtained criterion are less conservative because free-weighting matrices method and a convex optimization approach are considered. Finally, numerical examples are given to demonstrate the effectiveness of the proposed method.

    A case of cervical plexus neuropathy was reported in association with chronic radio-dermatitis, myxedema with thyroid adenoma and epiglottic tumor. A 38-year-old man has noticed muscle weakness and wasting of the right shoulder girdle since age 33. A detailed history taking revealed a previous irradiation to the neck because of the cervical lymphadenopathy at age 10 (X-ray 3,000 rads), keroid skin change at age 19, obesity and edema since 26, and hoarseness at 34. Laryngoscopic examination revealed a tumor on the right vocal cord, diagnosed as benign papilloma by histological study. In addition, there were chronic radio-dermatitis around the neck, primary hypothyroidism with a benign functioning adenoma on the right lobe of the thyroid, the right phrenic nerve palsy and the right recurrent nerve palsy. All these lesions were considered to be the late sequellae of radiation to the neck in childhood. Other neurological signs were weakness and amyotrophy of the right shoulder girdle with patchy sensory loss, and areflexia of the right arm. Gross power was fairly well preserved in the right hand. EMG showed neurogenic changes in the tested muscles, suggesting a peripheral nerve lesion. Nerve conduction velocities were normal. No abnormal findings were revealed by myelography and spinal CT. The neurological findings of the patient were compatible with the diagnosis of middle cervical plexus palsy apparently due to late radiation effect. In the literature eight cases of post-radiation neuropathy with a long latency have been reported. The present case with the longest latency after the radiation should be included in the series of the reported cases of ''delayed radiation neuropathy.'' (author).

    The Quebec Pain Registry (QPR) is a large research database of patients suffering from various chronic pain (CP) syndromes who were referred to one of five tertiary care centres in the province of Quebec (Canada). Patients were monitored using common demographics, identical clinical descriptors, and uniform validated outcomes. This paper describes the development, implementation, and research potential of the QPR. Between 2008 and 2013, 6902 patients were enrolled in the QPR, and data were collected prior to their first visit at the pain clinic and six months later. More than 90% of them (mean age ± SD: 52.76 ± 4.60, females: 59.1%) consented that their QPR data be used for research purposes. The results suggest that, compared to patients with serious chronic medical disorders, CP patients referred to tertiary care clinics are more severely impaired in multiple domains including emotional and physical functioning. The QPR is also a powerful and comprehensive tool for conducting research in a “real-world” context with 27 observational studies and satellite research projects which have been completed or are underway. It contains data on the clinical evolution of thousands of patients and provides the opportunity of answering important research questions on various aspects of CP (or specific pain syndromes) and its management.

    People living with HIV (PWHIV) face negative attitudes that isolate and discourage them from accessing services. Understanding negative attitudes and the social environment can lead to more effective health promotion strategies and programs. However, a scale to measure attitudes has been lacking. We developed and validated attitudes toward PWHIV Scale to examine trends in attitudes toward PWHIV in Quebec in 1996, 2002, and 2010. We also examined the relationship between negative attitudes toward PWHIV, homophobia, and knowledge about HIV transmission. The scale included 16 items and had a five-factor structure: F1 (fear of being infected), F2 (fear of contact with PWHIV), F3 (prejudicial beliefs toward groups at high risk of HIV), F4 (tolerance regarding sexual mores and behaviors), and F5 (social support for PWHIV). The validity and reliability of the scale were assessed and found to be high. Overall, Quebecers had positive attitudes toward PWHIV, with more negative attitudes observed in subgroups defined as male, ≥50 years of age, homophobia, and below-average knowledge about HIV transmission. Scores were stable between 1996 and 2002, and increased in 2010. Negative attitudes were correlated with higher levels of homophobia and lesser knowledge about HIV transmission. The lowest scores for each factor were observed in the same subgroups that had low overall scores on the Attitudes Scale. The findings from this study can be used to intensify interventions that promote compassion for PWHIV, address attitudes toward homosexuality, and encourage greater knowledge about the transmission of HIV in these subgroups.

    Basic nursing education has a major impact on the future professional practices of nurses. Nurses must be adequately trained to perform health promotion activities, such as smoking cessation. However, nurses play only a minor role in this field. The objective of this research was to describe the smoking cessation content in basic nursing programmes in Quebec. A simple descriptive mixed design (quantitative and qualitative) study was conducted among nursing programme administrators in Quebec, using a validated online questionnaire. On average, the time devoted to smoking cessation was reported to be less than one hour per year, essentially concerning the physiological and pathophysiological factors of tobacco consumption, while nursing professional assessment and counselling in smoking cessation were almost non-existent. The results confirm the need to increase and improve the time and content devoted to smoking cessation in the basic nursing education curriculum. It is also important to structure basic training courses so to improve knowledge, attitudes, and skills of future nurses in order to influence their role in smoking cessation in their future professional practice.

    New designs of care in orthopaedic clinics are needed to cope with the shortage of orthopaedic surgeons and the lengthening of waiting times. To assess the effectiveness of an interdisciplinary orthopaedic clinic with a pivot nurse in the Canadian province of Quebec with regard to accessibility, quality of care, efficacy and efficiency of the clinic, and patient's quality of life. Two strategies were developed: (1) a selected cohort of new patients attending an orthopaedic service from February to September 2008 were entered into a database recording patient details, source of referral, diagnosis, satisfaction, and quality of life (36-Item Short Form Health Survey version 2). In this setting, 2 sets of questionnaires were administered to the patients: the first one during the first visit and the second one, 2 months later. A total of 243 patients from the case control were compared with 89 patients of the case study, where an interdisciplinary orthopaedic clinic with a pivot nurse has been developed; (2) costs per patient were calculated using the staff timesheets provided by the two orthopaedic clinics. The results showed a significant reduction in the waiting-list duration (accessibility) in the case study clinic owing to a strong decrease in the inappropriate consultations with the orthopaedic consultant. The quality of care remained high, and the target surgeries for total hip and knee replacement were reached, despite a strong shortage of orthopaedic doctors. Interdisciplinary orthopaedic clinic with a pivot nurse is a new approach in the province of Quebec and first results are encouraging.

    Despite vaccination, cyclical peaks of Bordetella pertussis incidence rates are still observed in Canada and other developed countries, making pertussis one of the most prevalent vaccine preventable bacterial diseases. In the postacellular vaccine era, evolution of bacterial strains has resulted in strains with altered vaccine antigens. Previous Canadian studies have focused on isolates mainly from the provinces of Ontario and Alberta, with only small numbers of isolates from other provinces. Therefore, in this study, we examined a larger sample (n = 52) of isolates from Quebec, Canada, between 2002 and 2014. Isolates were characterized by serotype, sequence type, and prevalence of pertactin deficiency. The Quebec isolates shared characteristics similar to other Canadian isolates and to isolates circulating globally. Although pertactin-deficient isolates were not present, a significant shift in sequence type was observed in more recent years. This study highlights the importance of continually monitoring disease-causing isolates to track evolutionary trends and gain a better understanding of the molecular epidemiology of pertussis in Canada.

    Game meat from animals killed by lead ammunition may expose consumers to lead. We assessed the risk related to lead intake from meat consumption of white-tailed deer and moose killed by lead ammunition and documented the perception of hunters and butchers regarding this potential contamination. Information on cervid meat consumption and risk perception were collected using a mailed self-administrated questionnaire which was addressed to a random sample of Quebec hunters. In parallel, 72 samples of white-tailed deer (n = 35) and moose (n = 37) meats were collected from voluntary hunters and analysed for lead content using inductively coupled plasma-mass spectrometry. A risk assessment for people consuming lead shot game meat was performed using Monte Carlo simulations. Mean lead levels in white-tailed deer and moose killed by lead ammunition were 0.28 and 0.17 mg kg(-1) respectively. Risk assessment based on declared cervid meat consumption revealed that 1.7% of the surveyed hunters would exceed the dose associated with a 1 mmHg increase in systolic blood pressure (SBP). For consumers of moose meat once, twice or three times a week, simulations predicted that 0.5%, 0.9% and 1.5% of adults would be exposed to a dose associated with a 1 mmHg increase in SBP, whereas 0.9%, 1.9% and 3.3% of children would be exposed to a dose associated with 1 point intelligence quotient (IQ) decrease, respectively. For consumers of deer meat once, twice or three times a week, the proportions were 1.6%, 2.9% and 4% for adults and 2.9%, 5.8% and 7.7% for children, respectively. The consumption of meat from cervids killed with lead ammunition may increase lead exposure and its associated health risks. It would be important to inform the population, particularly hunters, about this potential risk and promote the use of lead-free ammunition.

    Full Text Available Abstract Background The quality of the relationship with the spouse/partner appears crucial among patients with multiple chronic conditions where illness management is complex and multifaceted. This study draws on data from the Quebec Health Survey (QHS to examine, among patients with one or more chronic conditions, the relation between marital status, the perceived conflict with the spouse/partner, and what the patients do to manage their illness as well as how they perceive their health. Methods Data from the QHS 1998 were used. The sample included 7547 coupled adults who had one or more chronic health problems lasting more than 6 months. Independent variables included marital status, perceived conflict with the spouse/partner, and the number of chronic conditions. Illness management was defined broadly as a measure of the patient's efforts at self-care and an illness status indicator, including visits to the generalist and the specialist, the use of telephone health line in the last 12 months, self-rated general health, mental health, and a measure of psychological distress. Linkages between the independent variables and illness management were assessed for males and females separately with logistic regressions, while accounting for the survey sampling design and household clustering. Results Female patients who did not live with their partner and had never been married were more likely to report a negative perception of their general health and a higher psychological distress than those who were married. Perceived conflict with the partner was linked to a negative perception of mental health and a higher psychological distress among both men and women. Compared to patients with only one chronic condition, males who reported more than one chronic condition were more likely to have consulted a generalist prior to the survey and used the telephone health line, whereas females were more likely to have consulted a specialist. Both males and

    Abstract Introduction: Intravascular large B-cell lymphoma (IVL) is an extremely rare malignancy, mainly studied through European and Asian series. Due to the low incidence of this condition, our understanding of the clinical presentation as well as the management of IVL relies on a limited number of patients. We report the largest North American study to date on IVL with 29 cases from Quebec hospital diagnosed between 1990 and 2016. The aim of our study is to describe the clinical presentations, diagnostic and staging procedures, therapeutic management and clinical outcomes of IVL patients in our population and compare the disease phenotype to European and Asian series reported. In our cohort, all patients had stage IV IVL at diagnosis, with a median age of 66.7 years (range 47.2–90.8). Clinical presentation was characterized by constitutional symptoms (100%), poor ECOG-PS (100% ≥ 2), cytopenias (93% anemia), and elevated lactate dehydrogenase (97%) and C-reactive protein (96%). Our cohort presented with mainly cutaneous and neurological symptoms. However, neurological involvement (75.9%) was predominant and no “cutaneous variant” was observed; this differs from European literature, where “classical” IVL is reported with mainly cutaneous involvement. Two of our Caucasian patients presented “Asian variant” IVL; this observation is not unusual, as cases of “classical” IVL have been reported in Asians and “Asian variant” IVL has been reported in Europeans. All patients were classified according to their immunophenotypic features in 3 different subgroups (CD5+ or CD5−CD10+, CD5−CD10−, CD5+CD10−) with no difference in outcome. Finally, 62% of our cohort received anthracycline-based chemotherapy and 53% of them achieved a complete response. After a median follow-up of 328 days, OS at 3 years was 42.7% for the entire cohort and 47.4% for the cases with in vivo diagnosis. Conclusion: Unlike European studies on “classical” IVL, our study

The essay will evidence the long march towards hospitals without walls, interdisciplinary work, tension between cure and rehabilitation and a relative decreasing budget. This in conjunction with vulnerability in organisation and leadership, attributed to tension or burn out has revealed system deficits like the trans-institution towards homelessness or towards the judiciary system. The essay will conclude with a discussion on the opportunities and challenges of the very new Law 10 that reforms the general governance of the provincial and regional health and social services and hopes for a more balanced mental health care system in Quebec.

    Hydrothermally altered andesites in the upper member of the Amulet formation at Buttercup Hill, Noranda, Quebec represent part of the aquifer and cap of a self-sealing geothermal system that focussed the discharge of hydrothermal fluids during the formation of massive Cu-Zn sulfide deposits. Five alteration facies are recognized pervasive greenschist faciés regional metamorphism (least-altered andesite) epidotization-silicification albitization-silicification chloritization sericitization-silicification. Alteration is localized on permeable zones such as amygdules, fractures, flow tops, discordant breccia dikes, and conformable breccia horizons. Epidotized-silicified andesite is enriched in Ca-Sr-Eu and depleted in Mg and first transition series metals (FTSM) relative to least-altered andesite. Albitized-silicified andesite is significantly enriched in Na and depleted in most FTSM relative to least-altered andesite. The abundances and inter-element ratios of the rare-earth elements (REE) and most high field-strength elements (HFS: Y, Zr, Th, U, Hf, Ta) are similar in least-altered, epidotized-silicified and albitized-silicified andesites. The most silicified andesites are strongly enriched in Na-Si, strongly depleted in Mg and divalent FTSM and slightly but systematically depleted in REE and most HFS elements. Serialized andesites were previously silicified; they are very strongly enriched in K-Rb-Cs-Ba, very strongly depleted in Na-Ca-Sr-Eu and slightly depleted in light REE relative to silicified andesite. Chloritized andesitic rocks exhibit heavy REE and HFS element ratios similar to those of leastaltered andesite, but are relatively strongly enriched in Mg and divalent FTSM, strongly depleted in Si and large ion lithophile (LIL) elements and slightly depleted in light REE. The coupled behavior of the heavy REE and most HFS elements during epidotization, albitization, silicification, chloritization and serialization suggests that they were inert during

    2007-01-01

    Construction aggregates, primarily stone, sand and gravel, are recovered from widespread naturally occurring mineral deposits and processed for use primarily in the construction industry. They are mined, crushed, sorted by size and sold loose or combined with portland cement or asphaltic cement to make concrete products to build roads, houses, buildings, and other structures. Much smaller quantities are used in agriculture, cement manufacture, chemical and metallurgical processes, glass production and many other products.

    2012-10-01

    Full Text Available Purpose: The main objective of this paper is to examine how the customers' perceptions of delays and safety relate to each other and to behavioral intentions.Design/methodology/approach: We modified a customer satisfaction questionnaire to include questions relating to the constructs we wanted to examine and collaborated with a major international airline to collect data from 797 customers through in-flight surveys.Findings: We obtain three key original findings. First, perceived safety exerts a direct positive effect on behavioral intentions. Second, perceived delays exert an indirect effect mediated by perceived safety. Finally, customers believe operational practices affect both delay and safety.Originality/value: This is the first paper that examines the customer's perspective on two of the most important aspects of airline operations management: delays and safety. Our findings are of great value to managers who want to evaluate the impact of delays and safety on customers and to researches interested in the theoretical relationships between these two constructs.

  11. Time Delay in Molecular Photoionization

    CERN Document Server

    Hockett, P; Villeneuve, D M; Corkum, P B

    2015-01-01

    Time-delays in the photoionization of molecules are investigated. As compared to atomic ionization, the time-delays expected from molecular ionization present a much richer phenomenon, with a strong spatial dependence due to the anisotropic nature of the molecular scattering potential. We investigate this from a scattering theory perspective, and make use of molecular photoionization calculations to examine this effect in representative homonuclear and hetronuclear diatomic molecules, nitrogen and carbon monoxide. We present energy and angle-resolved maps of the Wigner delay time for single-photon valence ionization, and discuss the possibilities for experimental measurements.

    2009-01-01

    We establish two theorems for two time-delayed (chaotic) differential equation systems to achieve time-delayed generalized synchronization (TDGS). The theorems uncover general forms of two TDGS systems via a prescribed differentiable transformation. Based on the theorems, we use two-coupled Ikeda equations as the driving system to construct TDGS driven systems via two prescribed transformations. Numerical simulations demonstrate the effectiveness of the proposed theorems. It may be expected that our theorems provide new tools for understanding and studying TDGS phenomena.

    We study stochastic delay differential equations (SDDE) where the coefficients depend on the moving averages of the state process. As a first contribution, we provide sufficient conditions under which the solution of the SDDE and a linear path functional of it admit a finite-dimensional Markovian representation. As a second contribution, we show how approximate finite-dimensional Markovian representations may be constructed when these conditions are not satisfied, and provide an estimate of the error corresponding to these approximations. These results are applied to optimal control and optimal stopping problems for stochastic systems with delay.

    An attempt was made to reproduce the systematic trend observed in the delayed neutron yields for actinides on the basis of the five-Gaussian representation of the fission yield together with available data sets for delayed neutron emission probability. It was found that systematic decrease in DNY for heavier actinides is mainly due to decrease of fission yields of precursors in the lighter side of the light fragment region. (author)

  8. Measuring information-transfer delays.

    Directory of Open Access Journals (Sweden)

    Michael Wibral

    Full Text Available In complex networks such as gene networks, traffic systems or brain circuits it is important to understand how long it takes for the different parts of the network to effectively influence one another. In the brain, for example, axonal delays between brain areas can amount to several tens of milliseconds, adding an intrinsic component to any timing-based processing of information. Inferring neural interaction delays is thus needed to interpret the information transfer revealed by any analysis of directed interactions across brain structures. However, a robust estimation of interaction delays from neural activity faces several challenges if modeling assumptions on interaction mechanisms are wrong or cannot be made. Here, we propose a robust estimator for neuronal interaction delays rooted in an information-theoretic framework, which allows a model-free exploration of interactions. In particular, we extend transfer entropy to account for delayed source-target interactions, while crucially retaining the conditioning on the embedded target state at the immediately previous time step. We prove that this particular extension is indeed guaranteed to identify interaction delays between two coupled systems and is the only relevant option in keeping with Wiener's principle of causality. We demonstrate the performance of our approach in detecting interaction delays on finite data by numerical simulations of stochastic and deterministic processes, as well as on local field potential recordings. We also show the ability of the extended transfer entropy to detect the presence of multiple delays, as well as feedback loops. While evaluated on neuroscience data, we expect the estimator to be useful in other fields dealing with network dynamics.

  10. Basin stability in delayed dynamics

    Science.gov (United States)

    Leng, Siyang; Lin, Wei; Kurths, Jürgen

    2016-02-01

    Basin stability (BS) is a universal concept for complex systems studies, which focuses on the volume of the basin of attraction instead of the traditional linearization-based approach. It has a lot of applications in real-world systems especially in dynamical systems with a phenomenon of multi-stability, which is even more ubiquitous in delayed dynamics such as the firing neurons, the climatological processes, and the power grids. Due to the infinite dimensional property of the space for the initial values, how to properly define the basin’s volume for delayed dynamics remains a fundamental problem. We propose here a technique which projects the infinite dimensional initial state space to a finite-dimensional Euclidean space by expanding the initial function along with different orthogonal or nonorthogonal basis. A generalized concept of basin’s volume in delayed dynamics and a highly practicable calculating algorithm with a cross-validation procedure are provided to numerically estimate the basin of attraction in delayed dynamics. We show potential applicabilities of this approach by applying it to study several representative systems of biological or/and physical significance, including the delayed Hopfield neuronal model with multistability and delayed complex networks with synchronization dynamics.

    A close-to-ideal blend of suburb and city, speedy construction of towers of Babylon, the sparkling proportion of glass and steel buildings’ facade at night showcase the wisdom of humans. They also witness the footsteps, sweats and tears of architects and engineers. Unfortunately, these signatures of human civilizations are swathed in towering figures of construction accidents. Fretting about these on sites, different countries adopt different measures on sites. This book firstly sketches the construction accidents on sites, followed by a review on safety measures in some of the developing countries such as Bermuda, Egypt, Kuwait and China; as well as developed countries, for example, the United States, France and Singapore. It also highlights the enormous compensation costs with the courts’ experiences in the United Kingdom and Hong Kong.

    The spectacular progress made by nanosciences and nanotechnologies elicits as much hope and fear. Consequently, a great number of research and training initiatives on the ethical, environmental, economic, legal and social issues regarding nanotechnology development (Ne{sup 3}LS) are emerging worldwide. In Quebec, Canada, a Task Force was mandated by NanoQuebec to conceive a Ne{sup 3}LS research and training strategy to assess those issues. This Task Force brought together experts from universities, governments or industry working in nanosciences and nanotechnologies or in Ne{sup 3}LS. Their resulting action plan, made public in November 2006, contained several recommendations, including the creation of a knowledge network (Ne{sup 3}LS Network). In the following years, after consulting with numerous key players concerned with the possible impacts of nanosciences and nanotechnologies in Quebec, the Ne{sup 3}LS Network was launched in January 2010 in partnership with the Fonds quebecois de la recherche sur la nature et les technologies, the Fonds quebecois de la recherche sur la societe et la culture and the Fonds de la recherche en sante du Quebec, NanoQuebec, the Institut de recherche Robert-Sauve en sante et en securite du travail as well as the University of Montreal. Its objectives are to 1) Foster the development of Ne{sup 3}LS research activities (grants and fellowships); 2) Spearhead the Canadian and international Ne{sup 3}LS network; 3) Take part in the training of researchers and experts; 4) Encourage the creation of interactive tools for the general public; 5) Facilitate collaboration between decision-makers and experts; 6) Involve the scientific community through a host of activities (symposium, conferences, thematic events); 7) Build multidisciplinary research teams to evaluate the impact of nanotechnology.

    2015-11-01

    Global asymptotic stability and synchronization of a class of fractional-order memristor-based delayed neural networks are investigated. For such problems in integer-order systems, Lyapunov-Krasovskii functional is usually constructed, whereas similar method has not been well developed for fractional-order nonlinear delayed systems. By employing a comparison theorem for a class of fractional-order linear systems with time delay, sufficient condition for global asymptotic stability of fractional memristor-based delayed neural networks is derived. Then, based on linear error feedback control, the synchronization criterion for such neural networks is also presented. Numerical simulations are given to demonstrate the effectiveness of the theoretical results.

    Since the advent of new nanotechnologies, the variability of gate delay due to process variations has become a major concern. This paper proposes a new gate delay model that includes impact from both process variations and multiple input switching. The proposed model uses orthogonal polynomial based probabilistic collocation method to construct a delay analytical equation from circuit timing performance. From the experimental results, our approach has less that 0.2% error on the mean delay of gates and less than 3% error on the standard deviation.

First, by construction of a newly augmented Lyapunov-Krasovskii functional, a delay-dependent stability criterion for nominal systems with time-varying delays is established in terms of linear matrix inequalities (LMIs. Second, based on the H∞ sense, the proposed method is extended to solve the problem of designing an H∞ output tracking controller to track the output of a given reference model. Finally, three examples are included to show the validity and effectiveness of the presented delay-dependent stability and the H∞ output tracking controller design.

The time delay is any continuous function belonging to a given interval, but not necessary to be differentiable. By constructing a suitable augmented Lyapunov-Krasovskii functional combined with Leibniz-Newton’s formula, a switching rule for the mean square exponential stability of switched stochastic system with interval time-varying delays and new delay-dependent sufficient conditions for the mean square exponential stability of the switched stochastic system are first established in terms of LMIs. Numerical example is given to show the effectiveness of the obtained result.

    Xu, Chang-Jin; Li, Pei-Luan

    2017-03-01

    This paper is concerned with high-order neural networks with proportional delays. The proportional delay is a time-varying unbounded delay which is different from the constant delay, bounded time-varying delay and distributed delay. By the nonlinear transformation {y}i(t)={u}i({{{e}}}t){{ }}(i=1,2,\\ldots ,n), we transform a class of high-order neural networks with proportional delays into a class of high-order neural networks with constant delays and time-varying coefficients. With the aid of Brouwer fixed point theorem and constructing the delay differential inequality, we obtain some delay-independent and delay-dependent sufficient conditions to ensure the existence, uniqueness and global exponential stability of equilibrium of the network. Two examples with their simulations are given to illustrate the theoretical findings. Our results are new and complement previously known results.
