    L’électricitĂ© est-elle un bien public ?

    La fourniture d’électricitĂ© s’organise de plus en plus autour de marchĂ©s dĂ©centralisĂ©s encadrĂ©s par les rĂšgles de la concurrence. Or les pannes survenues sur les rĂ©seaux Ă©lectriques dans certaines rĂ©gions du monde ces derniĂšres annĂ©es suggĂšrent que ces rĂšgles ne sont pas compatibles avec la position selon laquelle la sĂ©curitĂ© d’approvisionnement en Ă©lectricitĂ© est un bien public. L’objectif de cet article est de montrer que cette sĂ©curitĂ©, et plus gĂ©nĂ©ralement la fourniture d’électricitĂ©, est un bien composite, Ă  la fois public impur et privĂ©. Il souligne le fait, apparemment occultĂ© dans les dĂ©bats publics actuels mais pourtant bien connu des gestionnaires de rĂ©seaux de transport, que la fiabilitĂ© varie gĂ©ographiquement. Cela a des implications concernant la demande de sĂ©curitĂ© d’approvisionnement. Alors que le caractĂšre de bien public explique pourquoi certaines entreprises prĂ©fĂšrent que d’autres investissent pour maintenir un niveau de sĂ©curitĂ©, le caractĂšre de bien privĂ© renvoie Ă  l’existence de prĂ©fĂ©rences diffĂ©renciĂ©es pour cette sĂ©curitĂ©. Le caractĂšre composite de la fourniture d’électricitĂ© a des implications pour la politique de rĂ©gulation de la sĂ©curitĂ© d’approvisionnement dans le secteur de l’énergie Ă©lectrique, ce que nous dĂ©montrons en nous appuyant sur le concept d’externalitĂ© politiquement pertinente. Les dĂ©cideurs publics ne devraient pas, par exemple, chercher Ă  faire payer Ă  tous les usagers, et de maniĂšre uniforme, un investissement visant Ă  amĂ©liorer la sĂ©curitĂ© d’approvisionnement sur la seule base qu’ils en retirent un effet externe positif. Il est pertinent qu’ils paient pour cette amĂ©lioration seulement dans le cas oĂč ce paiement viendrait affecter leurs propres dĂ©cisions de consommation. Ce rĂ©sultat suggĂšre l’intĂ©rĂȘt d’un marchĂ© de sĂ©curitĂ© Ă  la carte, complĂ©mentaire des marchĂ©s de gros, Ă  condition que les coĂ»ts de transaction ne soient pas Ă©levĂ©s

    The Role Of Character In The Hiring Process: A Pilot Study Survey Of College Seniors Potential Employers

    Get PDF
    We surveyed 31 prospective employers (65% response rate) regarding their views on character as part of the employment selection process. The results showed character qualities superordinate, relative to skills that prospective employees bring to potential jobs. We discuss survey results in light of business educators responsibility for helping students to internalize ethical decision-making. Although the results show employers making few company changes due to the medias attention on corporate scandals, respondents express that the pool of applicants with strong character is shrinking. They expect that character training will occur prior to employment in a variety of milieuincluding higher education

    Towards practical reinforcement learning for tokamak magnetic control

    Reinforcement learning (RL) has shown promising results for real-time control systems, including the domain of plasma magnetic control. However, there are still significant drawbacks compared to traditional feedback control approaches for magnetic confinement. In this work, we address key drawbacks of the RL method; achieving higher control accuracy for desired plasma properties, reducing the steady-state error, and decreasing the required time to learn new tasks. We build on top of \cite{degrave2022magnetic}, and present algorithmic improvements to the agent architecture and training procedure. We present simulation results that show up to 65\% improvement in shape accuracy, achieve substantial reduction in the long-term bias of the plasma current, and additionally reduce the training time required to learn new tasks by a factor of 3 or more. We present new experiments using the upgraded RL-based controllers on the TCV tokamak, which validate the simulation results achieved, and point the way towards routinely achieving accurate discharges using the RL approach

    Dissolving the dichotomies between online and campus-based teaching: a collective response to The manifesto for teaching online (Bayne et al. 2020)

    Get PDF
    This article is a collective response to the 2020 iteration of The Manifesto for Teaching Online. Originally published in 2011 as 20 simple but provocative statements, the aim was, and continues to be, to critically challenge the normalization of education as techno-corporate enterprise and the failure to properly account for digital methods in teaching in Higher Education. The 2020 Manifesto continues in the same critically provocative fashion, and, as the response collected here demonstrates, its publication could not be timelier. Though the Manifesto was written before the Covid-19 pandemic, many of the responses gathered here inevitably reflect on the experiences of moving to digital, distant, online teaching under unprecedented conditions. As these contributions reveal, the challenges were many and varied, ranging from the positive, breakthrough opportunities that digital learning offered to many students, including the disabled, to the problematic, such as poor digital networks and access, and simple digital poverty. Regardless of the nature of each response, taken together, what they show is that The Manifesto for Teaching Online offers welcome insights into and practical advice on how to teach online, and creatively confront the supremacy of face-to-face teaching
