Due to the severity of system-wide power outages, though their probability of occurrence is slight, regulatory authorities require that a system restoration plan be drawn up and kept up to date at all times. The power outage that affected northeastern North America in 2003 proved the need for such a requirement. The particular structure of Hydro-Quebec's power system requires the use of a highly specific system restoration procedure. The daily preparation of the system restoration plan is based on a strategy whose application requires that a restoration sequence be drawn up that uses available equipment, the electrical behavior of which has been validated using appropriate studies. Over the…
Theories relating baryon asymmetry and dark matter
2014
The nature of dark matter and the origin of the baryon asymmetry are two of the deepest mysteries of modern particle physics. In the absence of hints regarding a possible solution to these mysteries, many approaches have been developed to tackle them simultaneously leading to very diverse and rich models. We give a short review where we describe the general features of some of these models and an overview on the general problem. We also propose a diagrammatic notation to label the different models.
Diagrammatic expansion for positive spectral functions beyond GW : Application to vertex corrections in the electron gas
2014
We present a diagrammatic approach to construct self-energy approximations within many-body perturbation theory with positive spectral properties. The method cures the problem of negative spectral functions which arises from a straightforward inclusion of vertex diagrams beyond the GW approximation. Our approach consists of a two-steps procedure: we first express the approximate many-body self-energy as a product of half-diagrams and then identify the minimal number of half-diagrams to add in order to form a perfect square. The resulting self-energy is an unconventional sum of self-energy diagrams in which the internal lines of half a diagram are time-ordered Green's functions whereas those…

Regulation of sailing sports during a race and civil liability of partecipants have a specific rule within the legal order of maritime law. The article focuses on pleasure navigation for sportive reasons, the level of sailing risk accepted by all partecipants, the damages occurring during a sailing race.
Ancient Theories of Reasoning
2013
In this section, the central question is whether we can find ancient discussions concerning what happens in the mind when a conclusion is drawn. Did ancient authors suppose that there is a psychological force that compels us to accept the conclusion when the premises are accepted and the inference is valid? Or, if the inference is not deductively valid but adds to the credibility of the conclusion in another way, e.g., by being inductive, what happens in the mind when such an inference is drawn? In general, psychology of reasoning was not a vital topic in antiquity. Reasoning was typically considered from a logical, not from a psychological point of view. For example, in Stoic sources the n…
Functional fixedness and functional reduction as common sense reasonings in chemical equilibrium and in geometry and polarity of molecules
2000
Many of the learning difficulties in the specific domain of chemistry are found not only in the ideas already possessed by students but in the strategic and procedural knowledge that is characteristic of everyday thinking. These defects in procedural knowledge have been described as functional fixedness and functional reduction. This article assesses the procedural difficulties of students (grade 12 and first and third year of university) based on common sense reasoning in two areas of chemistry: chemical equilibrium and geometry and polarity of molecules. In the first area, the theme of external factors affecting equilibria (temperature and concentration change) was selected because the ex…
The Role of Ciphering in Phenomenology of Life
2004
Contemporary philosophy is inseparable from the general tendencies of spiritual life that have dominated over the past centuries. The ruling tendency of European-type philosophy has been the affirmation of a democratic life style, liberal values and human individuality and creative activity. The testimony to this is the proportional growth of the philosophy of subjectivism since modern times, the division of pure practical reason and reasoning into separate spheres to substantiate fundamental human abilities, to analyse the ways of grasping the world — such as cognition, understanding, intuition, deciphering, experience — and describe man’s correlation with beingness (cosmos). Epistemology …
?What ought we do?? and other questions
2020
Kant formulates the question “What ought I do?” as an agent’s question. This is not the only way in which practical reasoning can be approached. A great deal of contemporary work in ethics and political philosophy addresses different, often narrower, questions. Much of it focuses primarily on recipients rather than agents, and so on entitlements or rights rather than on requirements or duties to act, including most obviously discussions of human rights. I will consider some of the consequences and the advantages of starting from each of these questions, and some of the ways in which each shapes practical reasoning.
The Epistemological Interpretation of Transcendental Idealism and Its Unavoidable Slide into Compatibilism
2019
This paper consists in two major parts. In the first part, I explain and defend Kant’s explicit rejection of compatibilist theories of freedom in the Critique of Practical Reason. I do this by a careful analysis of some contemporary compatibilist theories. In the second major part, I explain how the epistemological interpretation of Kant’s transcendental idealism inevitably degenerates into a compatibilist version of freedom. The upshot will be that epistemological interpretations of transcendental idealism are not viable because of their connection with compatibilism, which Kant rejected.
Hans Kelsen and Practical Reason
2017
The critique of practical reason, in all its possible forms, has a far more important and decisive role in Kelsen’s thought than the rejection of Natural law doctrine. Admitting that a practical use of reason is legitimate, namely, that there is a possible connection between intellect and will, would mean destroying the whole foundation of the scientific undertaking of the Pure Theory of law and its conception of the legal norm, which is its central aspect. By depriving practical reason of all foundation, any reference to agency and practical deliberation is excluded from Kelsen’s theory of law. Consequently, the Ought loses all capacity of attraction and motivation of human action, renderi…
