Machine stability and energy efficiency have become major issues in the manufacturing industry, primarily during the COVID-19 pandemic where fluctuations in supply and demand were common. As a result, Predictive Maintenance (PdM) has become more desirable, since predicting failures ahead of time allows to avoid downtime and improves stability and energy efficiency in machines. One type of machine failure stands out due to its impact, machine overstrain, which can occur when machines are used beyond their tolerable limit. From the current (...) literature, there are little to no relevant works that focus on machine overstrain failure detection or prediction. Accordingly, the purpose of this paper is to implement and compare four Machine Learning (ML) algorithms for PdM applied to machine overstrain failures: Artificial Neural Network (ANN), Gradient Boosting, Random Forest and Support Vector Machine (SVM). Moreover, it proposes a training methodology for imbalanced data and the automatic optimization of hyperparameters, which aims to improve performance in the ML models. To evaluate the performance of the ML models, a synthetic dataset that simulates industrial machine data is used. The obtained results show the robustness of the proposed methodology, with the ANN and SVM models achieving a perfect recall score, with 98.95% and 98.85% in accuracy, respectively. (shrink)

Latour is a world famous and widely published French sociologist who has written with great eloquence and perception about the relationship between people, science, and technology. He is also closely associated with the school of thought known as Actor Network Theory. In this book he sets out for the first time in one place his own ideas about Actor Network Theory and its relevance to management and organization theory.

Depuis l'entrée dans l'âge moderne de l'émancipation, c'est-à-dire depuis l'époque des Lumières et de la Révolution française, on admet en général que les juifs ont brisé un carcan qui les confinait dans des communautés fermées pour participer à la modernité européenne sans se renier et tout en restant juifs. Comment ce cheminement a-t-il eu lieu? Qu'a-t-il réellement impliqué, à la fois pour les juifs et pour les sociétés auxquelles ils s'intégraient? Bruno Karsenti reprend le fil de ce récit. Sous (...) l'angle philosophique, il examine les opérations intellectuelles par lesquelles certaines figures d'exception écrivain (Heine), sociologue (Durkheim), historiens (Salvador, Bloch), philosophe (Strauss) et linguiste (Benveniste) sont entrées dans cette modernité, au prix de quelles tensions et de quels efforts : comment ces hommes ont-ils pensé les liens entre judaïsme et modernité, et comment par là ont-ils éclairé les principes des sociétés démocratiques qui sont aujourd'hui les nôtres? À l'heure où les juifs d'Europe sont inquiets de leur avenir jusqu'à être parfois poussés au départ, à l'heure aussi où théologie et politique, loin de régler leurs rapports, se conjuguent en menace pour les démocraties elles-mêmes, ce livre cherche à redonner tout son sens à l'émancipation sociale et politique qui est notre héritage."--Page 4 of cover.

Dans cet essai, nous cherchons à ressaisir le sens politique du structuralisme à la lumière d’un rapprochement inattendu, présenté à la fin de Tristes Tropiques, entre le bouddhisme et le marxisme. On s’est beaucoup interrogé sur ce que le marxisme a apporté en propre à l’anthropologie structurale de Lévi-Strauss, et cela dès la parution du livre de Lucien Sebag, Marxisme et structuralisme, en 1964. Dans le même temps, le marxisme officiel, dans ses différentes tendances, avait attaqué une approche des structures (...) de l’esprit comme une dérive idéaliste. Nous avons voulu déplacer complètement la question en prenant à la lettre la comparaison audacieuse que risque Lévi-Strauss, en quelques pages, où le marxisme comparaît comme ce qui, en Occident, fait écho à un processus de transformation du monde social dont l’Orient, en son propre sein, a inscrit par avance la possibilité. Ainsi, c’est une différence interne à l’Orient qui sert, en bonne méthode structurale, à penser une différence significative, mais inaperçue, dans notre propre culture. Et la pensée marxiste, inscrite sous le signe d’une volonté de transformation du monde plutôt que d’interprétation, est replacée dans un cadre qui la modalise, en même temps qu’elle en révèle la portée réellement critique.

One might think that the problem of the subject has been exhausted by the debate that has taken place between post-Kantians and structuralists over the past several decades. In fact, this is true enough—at least if one considers the preferred arguments, the speculative arsenal, that has been mobilized by both positions in this debate. Still, it is now widely claimed, in France and elsewhere, that this debate had been overly theoretical, leaving the real problems of contemporary society quite untouched. With (...) the works Alain Ehrenberg and Pierre-Henri Castel have devoted over the past 10 years to transformations in the self-understanding and psychopathological structures of individuals, the question of the subject..

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Rethinking Music Education and Social Change by Alexandra Kertz-WelzelGraça MotaAlexandra Kertz-Welzel, Rethinking Music Education and Social Change (Oxford: Oxford University Press, 2022)I began to read this book shortly after the invasion of Ukraine by the Russian troops. Amidst this most terrible and brutal context, reading and re-reading the book that Alexandra Kertz-Welzel offers was both a blessing and an intense exercise of food for thought. A blessing as (...) it drives our minds through a complex but nonetheless rewarding journey into the meanders of critical and ideal visions. An exercise of food for thought as she turns to the arts, philosophy, sociology, and political theory to construct an interdisciplinary, sustained story. While rethinking “the goals of music education in view of social change,”1 the introduction describes the purpose of the study and presents the author’s chosen theoretical pillars: Levitas’s concept of utopia, Georgina Born’s four planes of music’s sociality, David Hesmondalgh’s defense of aesthetic experience, and Martha Nussbaum’s concept of human flourishing. Furthermore, Kertz-Welzel aims to answer the question of what social change is in general but also, concerning music education, to critically consider the contribution that music education can make to social change. She proposes to redefine “the general goals of music education regarding its social and musical intentions, reuniting two dimensions which have been defined as opposite, but are in fact complementary regarding [End Page 99] politically and socially responsive music education and esthetic music education.”2 I will get back later to this last intention in the context of the author’s approach to the redefinition of music education. For now, I will begin with her proposed definition of music education as utopian theory and practice, in the context of the chosen title for this book.Rethinking Music Education and Social Change is a very appealing title not only because rethinking music education is a most pressing issue within the community of music educators but also because social change, in relationship with music, has been the object of research in numerous projects, claiming the transformative power of music. This is a theme I have been very much involved with, being the co-founder of the research platform, Social Impact of Making Music (SIMM),3 that aims to systematically investigate the possible social impacts of learning and playing music. Having said that, I found myself confronted with a book that sets in the middle of its focus to thoroughly investigate the concept of utopia in its multiple facets based on a complete discussion of its theoretical basis. In that context, the fact that the title of the book does not include utopia seemed to me rather puzzling, and I intend to come back to this at the end of this review.The author presents a comprehensive and updated review of the literature, its complexities and ambivalences in the relationship between the arts and social change as it appears and has evolved across time. This approach connects social change with activism, not forgetting the issue of dramatic social change that she exemplifies with the COVID-19 pandemic, and to which we can now sadly add the present state of war. Quoting Roxane de la Sablonniére (2017) and her four typologies of social change, Kertz-Welzel highlights the fact that in the last hundred years the pace of change has increased enormously, and “dramatic social change is a threat to cultural identity.”4The notion of the arts as a political instrument is thoroughly developed, and it should be acknowledged that the author takes here, as well as in other parts of the book, a courageous standpoint. She does not avoid critical or uncomfortable issues, one of them being the ambiguity of the arts. In her discussion on social distinction and identity construction, she cites Max Weber, Georg Simmel, and Pierre Bourdieu and argues that culture has indeed been used as a way of discrimination among people. She also points out the supposedly refined taste of higher social classes cultivated through access to various arts experiences, while others would be denied these experiences and therefore unable to develop their full artistic potential...
