Lernende Organisationen in lehrreichen Netzwerken: Netzwerke als Ermöglichungsraum, in dem das Hilfesystem von seinen Adressat:innen lernen kann

Das vorliegend niedergeschriebene Manuskript wurde im Nachgang und als interpretative Auswertung eines vom Verfasser durchgeführten Workshops mit arbeitsmarktpolitischen Vertreter:innen eines Jobcenters zum Thema Alleinerziehende im SGB II-Bezug verfasst. Die nachfolgenden Ausführungen wurden dabei im Nachhinein so aufbereitet, dass für den Studienkontext der Sozialen Arbeit spezifische Erkenntnisse und Lerninhalte hervorgehoben werden. Es wird dafür sensibilisiert, dass Alleinerziehende – zwischen gesellschaftlichen Ansprüchen und institutionellen Funktionslogiken – in ihrem Alltag zu „Weltenwandler:innen“ werden; dies macht sie zu einer für die Netzwerkperspektive relevanten Gruppe. Es besteht das Ziel dieses Textes also darin, die Leser:innen auf eine kleine Reise durch die Idee von Netzwerken für Alleinerziehende mitzunehmen. Warum sind eigentlich gerade Alleinerziehende so relevant/aufschlussreich aus der Perspektive „Netzwerk“

Towards a multi-abrasive grinding model for the material point method

An efficient optimization of surface finishing processes can save high amounts of energy and resources. Because of the large occurring deformations, grinding processes are notoriously difficult to model using standard (mesh-based) micro-scale modeling techniques. In this work, we use the meshless material point method to study the influence of abrasive shape, orientation, rake angle, and infeed depth on the grinding result. We discuss the chip morphology, the surface topography, cutting versus plowing mode, the material removal rate, and the chip temperature. A generalization of our model from a straightforward single-abrasive approach to a multiple-abrasive simulation with pseudo-periodical boundary conditions greatly increases the degree of realism and lays the foundation for comparison with real finishing processes. We finally compare our results for multiple abrasives to those obtained for a scaled-down molecular dynamics system and discuss similarities and differences

The PLATO mission

PLATO (PLAnetary Transits and Oscillations of stars) is ESA’s M3 mission designed to detect and characterise extrasolar planets and perform asteroseismic monitoring of a large number of stars. PLATO will detect small planets (down to <2REarth) around bright stars (<11 mag), including terrestrial planets in the habitable zone of solar-like stars. With the complement of radial velocity observations from the ground, planets will be characterised for their radius, mass, and age with high accuracy (5%, 10%, 10% for an Earth-Sun combination respectively). PLATO will provide us with a large-scale catalogue of well-characterised small planets up to intermediate orbital periods, relevant for a meaningful comparison to planet formation theories and to better understand planet evolution. It will make possible comparative exoplanetology to place our Solar System planets in a broader context. In parallel, PLATO will study (host) stars using asteroseismology, allowing us to determine the stellar properties with high accuracy, substantially enhancing our knowledge of stellar structure and evolution. The payload instrument consists of 26 cameras with 12cm aperture each. For at least four years, the mission will perform high-precision photometric measurements. Here we review the science objectives, present PLATO‘s target samples and fields, provide an overview of expected core science performance as well as a description of the instrument and the mission profile towards the end of the serial production of the flight cameras. PLATO is scheduled for a launch date end 2026. This overview therefore provides a summary of the mission to the community in preparation of the upcoming operational phases

Supernatural Themes in the Art of Francisco De Goya. (Volumes I and II) (Spain).

Francisco de Goya's depictions of demons, monsters, witches, goblins, and other supernatural beings constitute a major part of his art. Most books and many articles on the Spanish master include some discussion of these works, but there is no detailed study devoted exclusively to them. The present investigation proposes to fill this lacuna by carefully examining the role that these supernatural beings play in many of Goya's series of paintings and etchings. It considers how and why these beings gradually assumed greater importance in his art and shows how they reached their climactic expression in the "Black Paintings" that the aged master created for his villa "La Quinta del Sordo." Chapter I of this study discusses the earliest appearances of the demonic in Goya's art and reveals that his first demonic beings of St. Francis Dorgia at the Deathbed of an Impenitent form an important part of the religious iconography of the Borgia Chapel in Valencia Cathedral. Chapter II traces the development of these creatures' progeny of witches, goblins, and other monsters from the Suenos to Los Caprichos, and Chapter III examines the six witchcraft paintings that the artist created for the Duke and Duchess of Osuna. These two chapters show that in both Los Caprichos and the Osuna witchcraft series Goya used supernatural beings based on characters from Spanish literature and folkloric beliefs to symbolize the superstitions, vices, and irrational social abuses of his age. Chapter IV analyzes the new monsters that appeared in Goya's art during and after the War of Independence and suggests that they were a concrete manifestation of the forces of reaction, oppression, and destruction unleashed by the war and its aftermath. Chapter V presents a detailed examination of the "Black Paintings." The terrifying images of Saturn devouring one of his sons, witches celebrating the Black Mass, flying demons, and ghoulish monks are shown to be Goya's symbolic representations of very real ecclesiastical and political monsters that had subjugated Spaniards for too long. The chapter concludes that these fourteen works are a testimony of the artist's disillusionment and of his hatred and intolerance of injustice.Ph.D.Fine artsUniversity of Michiganhttp://deepblue.lib.umich.edu/bitstream/2027.42/160529/1/8512423.pd
