Publication 100jahrebauhaus: Zu den politischen Dimensionen des Lichts(2019-01-24)Künstler wie Laszlo Moholy-Nagy waren beeindruckt von der Wirkmächtigkeit des Lichts und versuchten, diese in ihren Kunstkonzepten zur Geltung zu bringen. Die Totalität dieser Kunstidee wird eingeholt und zunichte gemacht in den totalitären Lichtinszenierungen der Nationalsozialisten.7 - Some of the metrics are blocked by yourconsent settings
Publication 19th-century Italian stage painting(2019-06-28)The beginning of the 19th century is a moment of decisive aesthetic changes for Italian and European scenography. Stage design moves from architectural constructions typical of the 18th century, marked by the Bibiena dynasty, to more painterly solutions like the « scena-quadro ». For instance, the illusion of depth is produced more by a specific use of colour and chiaroscuro effects - the so-called prospettiva aerea - than using geometrical structures. The scenographer becomes a painter and the stage a painting. Scholars have already defined the technical elements of these aesthetic changes through the study of treatises or indirect artifacts, such as sketches or engravings. Nevertheless, the recent discovery of original scenic material (wings, curtains, set pieces, backdrops, machinery,…) from the beginning of the 19th century in the theater of Feltre (IT) offers a unique opportunity to study these elements directly from the material itself in its own original context. This paper proposes to refine the study of historical scenography by observing these constitutive technical and aesthetic changes of stage painting, not only from treatises or sketches but also directly from rare original scenic elements of that period and see how this scenic material reflects the scientific research. The study of an Italian case is especially fascinating, as the artists from that country were known throughout the rest of Europe for their skill in stage painting. The work of Raphaël Bortolotti is focused on the original scenic material from the beginning of the 19th century in the historical theatre of Feltre, a small town north of Venice. After a Master’s degree in History of Art (University Lausanne) and another one in baroque singing (Schola Cantorum Basiliensis), Raphaël Bortolotti decided to prepare a Ph.D. at the University of Bern (HKB) on stage painting in Italy in the first half of the 19th century. Supervised by Maria Ida Biggi (Fondazione Cini) and Andreas Beyer (Universität Basel), he will start his Ph.D. during the following academic year.6 - Some of the metrics are blocked by yourconsent settings

Publication The 2015 European Refugee Event and Founder Social Identities: A Multi-Country and Multi-Level Study(2019-08); ;Hsueh, Josh Wei-Jun ;Sieger, PhilippVoegtlin, ChristianHow are founders’ social identities affected by societal trigger events? To address this question, we build on social identity literature and theorize how the abrupt and significant increase in the number of refugees in Europe in 2015 is related to the strength of Darwinian, Communitarian, and Missionary social identities of founders residing in the affected countries. Furthermore, we introduce a country’s percentage of foreigners before the 2015 refugee event as relevant contingency factor. Using a dataset of 6,841 nascent entrepreneurs from 24 European countries, we reveal a positive relationship between the 2015 refugee event and the strength of founders’ Communitarian identity. This relationship is even stronger when the previous percentage of foreigners in a country is lower. Interestingly, we do not find significant relationships between the refugee event and Darwinian or Missionary identities. Our study provides important contributions to the (founder) social identity literature and valuable implications for policy and practice.7 - Some of the metrics are blocked by yourconsent settings

Publication A Domain Model for Urban Digital TwinsThe term digital twin originated in the aerospace industry but has since also been applied to other sectors. In the light of the digital transformation of the public sector and the increasing developments towards smart cities, the concept also is being applied to cities, forming urban digital twins. This paper proposes a formal domain model for the concept of urban digital twins based on different approaches in the literature, aiming to clearly establish the terminology and facilitate further discussions on the topic.42 5 - Some of the metrics are blocked by yourconsent settings
Publication A escala comunitaria: un estudio sobre los aportes de la investigadora Beatriz Galán al campo del diseño industrial en Argentina(2023-10-04) ;Díaz, Valeria CynthiaEsta ponencia tiene como objetivo compartir los avances de una investigación en curso sobre los aportes metodológicos de la investigadora Prof. Dra. Beatriz Galán en el campo del Diseño Industrial (DI) en Argentina y su compromiso en la construcción de un nuevo perfil profesional en la carrera de DI de la Facultad de Arquitectura, Diseño y Urbanismo de la Universidad de Buenos Aires (FADU, UBA). En este sentido, proponemos abordar la escala comunitaria que abrió Beatriz Galán en la práctica profesional, impulsando un abordaje de los saberes proyectuales como una experiencia de investigación colectiva, dialogada y contextualizada.

Publication Abklärungen bei bestehender Beistandschaft(2024-09-05)Beistandspersonen kennen die Situation der Verbeiständeten und können bestehende oder neue Gefährdungslagen einschätzen. Diese Einschätzung und die Meldung von allfälligem Bedarf einer Änderung der Massnahme gehört denn auch zu den Aufga-ben der Beiständinnen und Beistände. Sind Beistandspersonen daher geeignet, um mit Abklärungen beauftragt zu werden? Ein solcher Auftrag offenbart einen Rollenkonflikt: Die vertieften Kenntnisse der Man-datstragenden hinsichtlich der persönlichen Verhältnisse der Betroffenen gehen mit einem Vertrauensverhältnis einher, welches ein wichtiges Element einer gelingenden Zusammenarbeit bildet. Durch eine abklärende, beurteilende und rapportierende Funktion der Beistandsperson kann diese Kooperation belastet werden. Dieses Span-nungsverhältnis stellt eine der Rolle der Beistandsperson immanente professionelle Herausforderung dar. Zugleich bedarf es einer Klärung sowohl seitens der auftragge-benden Behörde wie auch seitens der (allenfalls) ausführenden Beistandsperson, in welchen Konstellationen die Einschätzung und Abklärung einer Gefährdung als bei-standschaftlichen Auftrag erteilt oder aber an eine andere Person übertragen werden soll. Wenn eine Beistandsperson – allenfalls mit entsprechendem behördlichem Auftrag – eine Gefährdungseinschätzung vornimmt, sind verschiedene methodische Aspekte zu beachten. Diese betreffen die Vornahme der Abklärung bzw. der Einschätzung wie auch deren Dokumentation und die Kommunikation gegenüber der KESB mittels Be-richts, Antrags oder Meldung. Die Möglichkeiten des Vorgehens sowie der Rollen- und Aufgabenzuweisung zwi-schen KESB, Beistandsperson und weiteren Fachpersonen lassen sich auf einem Kontinuum zwischen einer integrierten, mandatsinternen Bearbeitung und einer sepa-rierten Abklärung durch externe Dritte verorten. Die Situierung möglicher Konstellati-onen in diesem Spektrum und der professionelle Umgang mit den sich jeweils stellen-den Herausforderungen werden in diesem Workshop diskutiert.16 5 - Some of the metrics are blocked by yourconsent settings
Publication About the Role of a Unique Personal Identifier in Collaboration Across Organizational BoundariesThis paper discusses the role of a unique personal identifier in cross-organizational government collaboration. It investigates the challenges public authorities face in identification processes and argues in favor of the use of the Swiss Social Security Number (SSN) as a unique identifier for Switzerland, and reviews concerns expressed against it. A unique identifier is seen as a relevant means in improving data quality level in base registries and hence, a central enabler for collaborative government.13 - Some of the metrics are blocked by yourconsent settings
