El presente libro constituye la biografía intelectual del autor, en la que relata cómo veintiún pensadores le hicieron caer del corcel del cristianismo sobre el que montaba tan seguro. Veintiún «impertinentes» que socavaron los cimientos que sustentaban su concepción del mundo y, por ende, de la educación. Si ignoramos qué es conocer, si hay o no algo absoluto —Dios—, qué significan los términos «bueno» y «malo», y si, además, no podemos responder de modo contundente a la pregunta «¿por qué tengo que ser bueno?», la axiología educativa se tambalea y hasta da la impresión de que va a dar en tierra de un momento a otro. Experto en filosofía de la educación, Octavi Fullat se propone estudiar las bases tanto de la epistemología de las ciencias de la educación como de la axiología educativa. Impertinentes narra la historia de esta peripecia.

Bilder werden nicht als Kunst geboren. Marcel Duchamp hatte mit seinen Readymades den Kunstbetrieb in eine Debatte über In- und Exklusion von Alltagsdingen in die ‚Hochkunst‘ verstrickt. Seitdem kann man mit Arthur Danto vom „Ende der Kunst“ sprechen. Duchamps Kunst-Erweiterung führte zu einer explosionsartigen Vermehrung von Kunstgegenständen und -begriffen, die bis in die Gegenwart anhält. Ferner provozieren Bilder und Objekte aus Nicht-Kunst-Bereichen mit eigener Tradition das Kunstsystem, indem sie Kunstkriterien adaptieren. Die Beiträge dieses Bandes handeln von Provokationen und Interventionen, den Transfers bzw. Vermischungen der Bild- und Objektkulturen und erforschen Bilder, Objekte und Aktionen in ihren kulturellen Kontexten, um dem sich in Auflösung befindenden Kunstsystem auf den Grund zu gehen. Images are not born as art. With his ready-mades Marcel Duchamp embro-iled the art business in a debate about the inclusion and exclusion of every-day objects in ‘high’ art. Since then, it has been possible to cite Arthur Danto and talk of the „end of art“. In retros-pect it becomes clear that Duchamp’s expansion of what constitutes art resulted in an explosive increase of art objects and concepts of art, a trend still evident today. Moreover, images and objects from non-art areas with their own tradition provoke the art system by adapting art criteria. The contributions in this book address pro-vocations and interventions, the trans-fer or melding of image and object cultures and explore images, objects and actions in their cultural contexts to get to the bottom of the art system that is in a state of dissolution.

The Lottery Ticket Hypothesis (LTH) suggests that randomly initialized overparametrized neural networks contain subnetworks which - when trained in isolation - are able to perform better than similar subnetworks whose architecture and weights are drawn randomly. Subnetworks matching the Lottery Ticket Hypothesis are referred to as winning tickets because they are the winners of the initialization lottery. An algorithm called Iterative Magnitude Pruning (IMP) was introduced to discover winning tickets. Finding well-performing sparse neural networks is especially interesting because of the potential large reduction in memory footprint and global computational burden. These combined may lead to an important reduction of the energy required to perform a same task. Deep Reinforcement Learning (DRL) has introduced algorithm capable of solving complex tasks (dynamic system control, Atari games, board games, ...). In this work we study the combination of deep reinforcement learning and the lottery ticket hypothesis. We focus on two algorithms namely Double Deep Q-Networks (DDQN) and Soft-Actor-Critic (SAC) which both belong to the fruitful class of value-based methods. We provide the third independent confirmation - in the context of deep reinforcement learning - of the existence of subnetworks matching the Lottery Ticket Hypothesis using Iterative Magnitude Pruning. Our experiments were carried on standard classic control as well as pixel-based environments. We provide experiments and guidelines regarding some important hyperparameters. We suggest a potential ability of winning tickets to robustly preserve low rank embeddings of the environment's state space. Some of ours results suggest that tickets found using IMP seem closer than expected to subnetworks that could be found using so-called structured pruning methods. Our experiments also showcase the ability of winning tickets to render inactive useless input variables while keeping good performance on the task. This result along with others indicate a potential ability of winning tickets to be used as feature importance extractors. Finally, a variant of Iterative Magnitude Pruning is introduced which we call pooled pruning. We suggest this variant could be beneficial for multi-networks algorithms such as Soft-Actor-Critic.

"Regarded as both a legend and a villain, the critic Dave Hickey has inspired generations of artists, art critics, musicians, and writers. His 1993 book The Invisible Dragon became a cult hit for its potent and provocative critique of the art establishment and its call to reconsider the role of beauty in art. His next book, 1997's Air Guitar, introduced a new kind of cultural criticism--simultaneously insightful, complicated, vulnerable, and down-to-earth--that propelled Hickey to fame as an iconoclastic thinker, loved and loathed in equal measure, whose influence extended beyond the art world. Far from Respectable is a focused, evocative exploration of Hickey's work, his impact on the field of art criticism, and the man himself, from his Huck Finn childhood to his drug-fueled periods as both a New York gallerist and Nashville songwriter to, finally, his anointment as a tenured professor and MacArthur Fellow. Drawing on in-person interviews with Hickey, his friends and family, and art world comrades and critics, Daniel Oppenheimer examines the controversial writer's distinctive takes on a broad range of subjects, including Normal Rockwell, Robert Mapplethorpe, academia, Las Vegas, basketball, country music, and considers how Hickey and his vision of an "ethical, cosmopolitan paganism" built around a generous definition of art is more urgently needed than ever before"--

This book explores the concept and facilitation of critical reflection and its implications for professional practice. It draws on the author’s own extensive experience to demonstrate how reflective processes involving metaphor and imagery, as well as critique, can be used not only to understand and articulate key values underpinning professional practice and to generate new theoretical models, but to explore one's own worldview, including the ultimate question: 'Who am I?’. The author incorporates practical examples of reflection-through-writing and other reflective techniques which illustrate how ideas about critical reflection, transformative learning, authenticity and spirituality are intricately entwined within theories and practices of adult learning and professional development. The book highlights the importance of understanding the relationship between personal worldviews, values and professional practice. It draws on the concepts of vocation and professional psychological wellbeing to consider what it means to act authentically as a professional within an audit culture. The book will be invaluable for practitioners, academics and students interested in critical reflection, educational inquiry, autoethnography and the use of the self in and as research, the nature and use of metaphor, and the development of worldviews.

Star Turns and Cameo Appearances is the entertaining and insightful memoir by veteran music critic Bernard Jacobson. Its pages are populated by eminent composers ranging from Hans Werner Henze to Andrzej Panufnik and by renowned performers, including Georg Solti, Daniel Barenboim, Sviatoslav Richter, and Jessye Norman.
As a music critic and orchestra administrator, Jacobson has had the opportunity to observe these outstanding musicians and many of their colleagues at close quarters. Assisting Riccardo Muti at the Philadelphia Orchestra for eight years, he saw sides of that maestro not visible to the music-loving public. Throughout Star Turns and Cameo Performances, Jacobson adds his own sensitive and sympathetic view to public perceptions of musical luminaries of yesterday and today, helping to explain and illuminate their artistry.
Bernard Jacobson has worked in the music field for over fifty years, including stints as recording executive, music critic of the Chicago Daily News, artistic director and adviser for international orchestras in Holland, and visiting professor at Roosevelt University's Chicago Musical College. He has also performed and recorded as narrator of concert works and opera.
