With the fast growth of wind power penetration into the electric grid, wind power forecasting plays an increasingly significant role in the secure and economic operation of power systems. Although there have been numerous studies concerning wind power forecasting, most of them have failed to make the best of the information implied in the error value, focused only on simple error correction, adopted a simple ensemble method to aggregate the predictions of each component, and considered improving only forecasting accuracy. Recognizing these issues, a novel two-stage forecasting model based on the error factor, a nonlinear ensemble method and the multi-objective grey wolf optimizer algorithm is proposed for wind power forecasting. More specially, in stage I, the extreme learning machine optimized by the multi-objective grey wolf optimizer is used to forecast the components decomposed by variational mode decomposition, and an error prediction model based on the extreme learning machine optimized by the multi-objective grey wolf optimizer is utilized to predict forecast errors; also, a novel nonlinear ensemble method based on the extreme learning machine optimized by the multi-objective grey wolf optimizer is utilized to integrate all the components and forecast error values in stage II. Three real-world wind power datasets collected from Canada and Spain are introduced to demonstrate the forecasting performance of the developed model. The forecasting results reveal that the proposed model is superior to all the other considered models in terms of both accuracy and stability and thus can be a useful tool for wind power forecasting.
En 1982, on assiste au Canada à une véritable refondation constitutionnelle. Ce moment est généralement vu comme l’émanation du génie d’un « Grand législateur », Pierre Elliott Trudeau, cherchant ...délibérément à mater le mouvement indépendantiste québécois. Or, cette interprétation de notre histoire récente est réductrice.Par une histoire sociopolitique du mouvement nationaliste constitutionnel, qui naît avec la Grande Dépression, ce livre montre comment Trudeau doit plutôt être compris comme le dernier acteur entré sur scène, qui s’appuie sur le scénario écrit par ses prédécesseurs, comme Francis Reginald Scott.La refondation de 1982 se dessine dès les années 1930. On cherche alors à ce que le Canada acquière sa pleine indépendance de Londres, qu’il se donne une charte des droits, à l’image du Bill of Rights étatsunien, que son droit devienne évolutif afin d’être au diapason des besoins changeants de la société et, enfin, que le nationalisme canadien supplante l’appartenance à l’Empire britannique. L’objectif ultime du projet nationaliste constitutionnel vise ainsi l’émancipation des individus égaux en droit face à un État devenant rapidement autoritaire en contexte de crise. Noble en soi, cette quête émancipatrice se révèle néanmoins un carcan dominateur pour les nations minoritaires. Celles-ci doivent effectivement accepter de se conformer aux normes du nouvel ordre constitutionnel et de se fondre dans une seule nation politique canadienne. En plus de nuancer et de situer le rôle joué par Trudeau, ce livre offre une analyse rigoureuse et accessible du déficit d’hospitalité du Canada envers ses nations minoritaires.
While almost all universal health coverage in Canada is provided
under the Canada Health Act, there is Medicare coverage that is
provided outside of the act. This is the first book to explain the
...nature of these boundary health services, why they exist, and how
to navigate them in practice. The Boundaries of Medicare
examines the complex range of public health care services and
coverage arrangements that predate or have developed alongside the
Canada Health Act. These provisions - including for workers'
compensation, military personnel and veterans, incarcerated
persons, migrants, and Indigenous Peoples - are often not well
understood, even by those working at policy and delivery levels.
Katherine Fierlbeck and Gregory Marchildon aim to improve
understanding of these boundary services: why they were
established, who is eligible for them, how services are provided,
how they are paid for, and how they are managed within a multilevel
governance system. They also look at the dramatic increase in
virtual health care services since the onset of the COVID-19
pandemic and their relationship to the Canada Health Act.
Explaining the origins, operations, and tensions of
government-funded health care outside the Canada Health Act,
The Boundaries of Medicare is an essential resource for
policymakers, providers, administrators, and patients seeking to
navigate Medicare in Canada.
Ubiquitous facial recognition technology can expose individuals' political orientation, as faces of liberals and conservatives consistently differ. A facial recognition algorithm was applied to ...naturalistic images of 1,085,795 individuals to predict their political orientation by comparing their similarity to faces of liberal and conservative others. Political orientation was correctly classified in 72% of liberal-conservative face pairs, remarkably better than chance (50%), human accuracy (55%), or one afforded by a 100-item personality questionnaire (66%). Accuracy was similar across countries (the U.S., Canada, and the UK), environments (Facebook and dating websites), and when comparing faces across samples. Accuracy remained high (69%) even when controlling for age, gender, and ethnicity. Given the widespread use of facial recognition, our findings have critical implications for the protection of privacy and civil liberties.
During the 2015 election, the Liberal Party of Justin Trudeau promised to make real change in the lives of all Canadians. It is a good opportunity, on the eve of the next election, to provide a ...rigorous and impartial assessment of how the Liberal government has delivered on its campaign promises. Under the direction of Lisa Birch and François Pétry, twenty renowned academics investigate the fate of the 353 liberal campaign promises in fields as varied as international relations, energy and sustainable development, the economy, Indigenous Reconciliation and the legalization of recreational cannabis. Collaborators draw from a common set of documentary sources and rely on a common method to analyze and contextualize the pledge fulfillment verdicts that area accessible on the Trudeau Polimeter website. Contrary to popular belief that politicians make empty promises, it appears that the Liberals in power have fulfilled at least in part the vast majority of their promises. The book concludes with a reflection on the relevance and meaning of campaign promises for Canadian democracy. In particular, we ponder the paradox that fulfilling most of your campaign promises does not necessarily create a sense of enthusiasm among voters.

The year 1968 in Canada was an extraordinary one, unlike any
other in its frenetic pace of activities and their consequences for
the development of a new national consciousness among
Canadians.
It ...was a year when decisions and actions, both in Canada and
outside its borders, were thick and contentious, and whose effects
were momentous and far-reaching. It saw the rise of Trudeaumania
and the birth of the Parti Québécois; the articulation of the new
nationalism in English Canada and an alternative vision for
Indigenous rights and governance; a series of public hearings in
the Royal Commission on the Status of Women; the establishment of
the Canadian Radio and Television Commission, nation-wide Medicare
and CanLit; and a striving for both a new relationship with the
United States and a more independent foreign policy everywhere
else. And more. Virtually no segment of Canadian life was untouched
by both the turmoil and the promise of generational change.

Climate change and global warming as the main human societies’ threats are fundamentally associated with energy consumption and GHG emissions. The residential sector, representing 27% and 17% of ...global energy consumption and CO2 emissions, respectively, has a considerable role to mitigate global climate change. Ten countries, including China, the US, India, Russia, Japan, Germany, South Korea, Canada, Iran, and the UK, account for two-thirds of global CO2 emissions. Thus, these countries’ residential energy consumption and GHG emissions have direct, significant effects on the world environment. The aim of this paper is to review the status and current trends of energy consumption, CO2 emissions and energy policies in the residential sector, both globally and in those ten countries. It was found that global residential energy consumption grew by 14% from 2000 to 2011. Most of this increase has occurred in developing countries, where population, urbanization and economic growth have been the main driving factors. Among the ten studied countries, all of the developed ones have shown a promising trend of reduction in CO2 emissions, apart from the US and Japan, which showed a 4% rise. Globally, the residential energy market is dominated by traditional biomass (40% of the total) followed by electricity (21%) and natural gas (20%), but the total proportion of fossil fuels has decreased over the past decade. Energy policy plays a significant role in controlling energy consumption. Different energy policies, such as building energy codes, incentives, energy labels have been employed by countries. Those policies can be successful if they are enhanced by making them mandatory, targeting net-zero energy building, and increasing public awareness about new technologies. However, developing countries, such as China, India and Iran, still encounter with considerable growth in GHG emissions and energy consumption, which are mostly related to the absence of strong, efficient policy.
In recent years, the world witnessed many devastating wildfires that resulted in destructive human and environmental impacts across the globe. Emergency response and rapid response for mitigation ...calls for effective approaches for near real-time wildfire monitoring. Capable of penetrating clouds and smoke, and imaging day and night, Synthetic Aperture Radar (SAR) can play a critical role in wildfire monitoring. In this communication, we investigated and demonstrated the potential of Sentinel-1 SAR time series with a deep learning framework for near real-time wildfire progression monitoring. The deep learning framework, based on a Convolutional Neural Network (CNN), is developed to detect burnt areas automatically using every new SAR image acquired during the wildfires and by exploiting all available pre-fire SAR time series to characterize the temporal backscatter variations. The results show that Sentinel-1 SAR backscatter can detect wildfires and capture their temporal progression as demonstrated for three large and impactful wildfires: the 2017 Elephant Hill Fire in British Columbia, Canada, the 2018 Camp Fire in California, USA, and the 2019 Chuckegg Creek Fire in northern Alberta, Canada. Compared to the traditional log-ratio operator, CNN-based deep learning framework can better distinguish burnt areas with higher accuracy. These findings demonstrate that spaceborne SAR time series with deep learning can play a significant role for near real-time wildfire monitoring when the data becomes available at daily and hourly intervals with the launches of RADARSAT Constellation Missions in 2019, and SAR CubeSat constellations.
•The impact of oil price uncertainty on economic growth in OECD countries is studied.•Taking a historic perspective, the sample covers a 144-year period starting in 1870.•The negative impact of ...uncertainty is more severe for oil producing countries.•A smaller impact is recorded in the post-World War II subsample period.•Reasons for declining impact of oil price uncertainty are proposed.
This paper uses a number of different panel data estimators, including fixed effects, bias-corrected least squares dummy variables (LSDVC), generalised methods of moments (GMM), feasible generalised least squares (FGLS), and random coefficients (RC) to analyse the impact of real oil price volatility on the growth in real GDP for 17 member countries of the Organisation for Economic Co-operation and Development (OECD), over a 144-year time period from 1870 to 2013. The main finding of the study is that oil price volatility has a negative and statistically significant impact on economic growth of the OECD countries in the sample. In addition, when allowing for slope heterogeneity, oil-producing countries are significantly negatively impacted by oil price uncertainty, most notably Norway and Canada.
