Technical analysis of a Central Asian wall painting detached from a Buddhist cave temple on the northern Silk Road
No full textA great number of Central Asian wall paintings, archeological materials, architectural fragments, and textiles, as well as painting fragments on silk and paper, make up the so called Turfan Collection at the Asian Art Museum in Berlin. The largest part of the collection comes from the Kucha region, a very important cultural center in the third to ninth centuries. Between 1902 and 1914, four German expeditions traveled along the northern Silk Road. During these expeditions, wall paintings were detached from their original settings in Buddhist cave complexes. This paper reports a technical study of a wall painting, existing in eight fragments, from the Buddhist cave no. 40 (Ritterhöhle). Its original painted surface is soot blackened and largely illegible. Grünwedel, leader of the first and third expeditions, described the almost complete destruction of the rediscovered temple complex and evidence of fire damage. The aim of this case study is to identify the materials used for the wall paintings. Furthermore, soot deposits as well as materials from conservation interventions were of interest. Non-invasive analyses were preferred but a limited number of samples were taken to provide more precise information on the painting technique. By employing optical and scanning electron microscopy, energy dispersive X-ray spectroscopy, micro X-ray fluorescence spectroscopy, X-ray diffraction analysis, and Raman spectroscopy, a layer sequence of earthen render, a ground layer made of gypsum, and a paint layer containing a variety of inorganic pigments were identified
4th Workshop on Context-Awareness in Retrieval and Recommendation
No full textContext-aware information is widely available in various ways and is becoming more and more important for enhancing retrieval performance and recommendation results. The current main issue to cope with is not only recommending or retrieving the most relevant items and content, but defining them ad hoc. Other relevant issues include personalizing and adapting the information and the way it is displayed to the user’s current situation and interests. Ubiquitous computing further provides new means for capturing user feedback on items and providing information

Teaching rationality : sustained shared thinking as a means for learning to navigate the space of reasons
No full textHuman thought can be characterised as being situated in the ‘space of reasons’. That is to say that human thought is guided by the norms of theoretical and practical rationality which, in turn, enable autonomous thinking. But how do children learn to navigate the space of reasons? Building on the work of Tugendhat and Bakhurst, among others, we argue, first, that this process involves the acquisition of propositional thought and that it is an essentially social one in which both children and adults take an active role. Second, and more specifically, by drawing on Brandom's theory of meaning, we provide a philosophical analysis of empirical findings with respect to the efficacy of ‘Sustained Shared Thinking’ (SST) in early educational settings. We argue that the efficacy of SST is based on its emphasising, modelling and practising those elements of communication that are essential for gaining proficiency in ‘playing the game of giving and asking for reasons’, namely drawing inferences between propositions and concepts and providing justifications for one's assertions. This is achieved by making explicit the inferential relationships between concepts and propositions and by the use of modal and doxastic markers that function as an invitation to a joint search for reasons
Anforderungsanalyse bei IT-Experten mit der Experience-Sample-Methode
No full textDieser Beitrag beschäftigt sich mit den Herausforderungen eine Anforderungsanalyse im hoch technologischen Umfeld der IT-Security durchzuführen, bei dem keine der üblichen ethnografischen Methoden wie teilnehmende Beobachtung u.a. möglich waren. Im Umfeld von IT-Sicherheitsexperten besteht grundsätzlich Skepsis bzgl. möglicher Datenerfassungen, die Sicherheitsbelange des eigenen IT-Sicherheits-Betriebes (ITS) betreffen. Diese muss vor allem in der Anforderungsanalyse beachtet werden. Welche Methode könnte hierbei also zum Einsatz kommen? Im Rahmen des Beitrages möchten wir unser Vorgehen und die gewonnen Erkenntnisse im Rahmen eines ZIM-Koop-Projektes des BMWi vorstellen und anhand eines Frameworks inkl. der Sample-Visualisierung der gewonnenen Daten zur Experience-Sample-Methode erläutern
Kritische Ethnografie in der Psychologie
No full textStefan Thomas führt in seinem Beitrag in die Grundlagen ethnografischer Forschung ein, die auf eine Aneignung sozialer Lebenswelten zielt. Obwohl teilnehmende Beobachtung im Mittelpunkt ethnografischer Feldforschung steht, bedient sich diese dem gesamten Arsenal empirischer Methodik – von Gesprächen und Interviews über die Analyse von Dokumenten bis hin zu standardisierten Fragebögen. Neben praktischen Hinweisen und möglichen Problemen beim Feldzugang, der Datenerhebung und -auswertung, diskutiert Thomas insbesondere das Verhältnis von Theorie und Empirie im Rahmen einer kritischen Ethnografie. Während kritischer Psychologie häufig eine Theorielastigkeit zu eigen ist und ethnografische Forschung sich bisweilen in Trivialitäten verliert, muss es kritischer Ethnografie gerade um eine angemessene Vermittlung (kritischer) Sozial- und Gesellschaftstheorie und Empirie gehen. Ethnografie benötigt dazu den Rückgriff auf Theorie, um nicht bei der ‚Kritik des Alltags‘ stehen zu bleiben. Demgegenüber liefert die empirische Sozialwelt zugleich das normative Fundament jeder – auch sozialwissenschaftlichen – Kritik. Würde sich die Psychologie stärker zur ethnografischen Feldforschung öffnen, könnte sie nicht nur an Lebens- und Alltagsweltnähe gewinnen, sondern sich auch endlich wieder den sozialwissenschaftlichen Nachbardisziplinen annähern
Ethnografie
No full textEthnografie ist in der akademischen Psychologie aufgrund der Eliminierung von Subjektivität und Lebenswelt nach wie vor eine vernachlässigte Methode. Ethnografie könnte – so die These im 1. Abschnitt – durch ihre Qualifikation als Feldforschung einen Beitrag zu einer stärkeren Orientierung der Psychologie auf reale Situationen und Handlungen in gesellschaftlichen Kontexten leisten. Ohne den Status eines anerkannten Verfahrens zu haben, lassen sich im 2. Abschnitt jedoch eine Vielzahl an Bezügen auf die Ethnografie historisch herausarbeiten. Im 3. Abschnitt wird gezeigt, dass über die Feldforschung hinaus der multi-modale Einbezug des diversen Angebots an Methoden der empirischen Sozialforschung wichtig ist, um eine Kontextualisierung der Forschung in der Sozialwelt zu bewerkstelligen. Entlang der zentralen Stationen werden im 4. Abschnitt typische Herausforderungen des ethnografischen Forschungsprozesses skizziert – vor allem: Feldzugang, Forschungsrollen, Datenerhebung und -auswertung sowie das Schreiben. Ethnografie erfordert, so wird am Ende aufgewiesen, eine gesonderte (meta-)theoretische Rahmung, damit diese sich in einer genuin sozialwissenschaftlichen Psychologie verorten lässt
Multilateral generation of violence : on the theorization of microscopic analyses and empirically grounded theories of violence
No full textUsing two phenomena of violence against children and intimate partner violence and based on two case studies, we explore the extent to which social processes of interpreting and negotiating violence contribute to further theorization efforts. The central unifying element is that both forms of violence are enabled and performed in power relations and have long been socially, legally, and politically legitimized. Therefore, our study’s focus is not on violence as a subject but rather on the social negotiation and construction of meanings of actions framed as violent. This perspective is exemplified by two independent case studies and data material that illustrate how such microscopic arguments are developed empirically. The methods used for the two case studies include qualitative analyses of interviews and organizational documents. Hence, we also discuss the researchers’ involvement and challenges in these processes. Based on our analytical findings, we argue for the use of an approach of a subject appropriated theorizing violence rather than a formal theory formation of violence. The procedural analysis of violence revealed its importance in making non-public and socially taboo forms of violence analytically accessible
Children’s Learning of Non-adjacent Dependencies Using a Web-Based Computer Game Setting
No full textInfants show impressive speech decoding abilities and detect acoustic regularities that highlight the syntactic relations of a language, often coded via non-adjacent dependencies (NADs, e.g., is singing). It has been claimed that infants learn NADs implicitly and associatively through passive listening and that there is a shift from effortless associative learning to a more controlled learning of NADs after the age of 2 years, potentially driven by the maturation of the prefrontal cortex. To investigate if older children are able to learn NADs, Lammertink et al. (2019) recently developed a word-monitoring serial reaction time (SRT) task and could show that 6–11-year-old children learned the NADs, as their reaction times (RTs) increased then they were presented with violated NADs. In the current study we adapted their experimental paradigm and tested NAD learning in a younger group of 52 children between the age of 4–8 years in a remote, web-based, game-like setting (whack-a-mole). Children were exposed to Italian phrases containing NADs and had to monitor the occurrence of a target syllable, which was the second element of the NAD. After exposure, children did a “Stem Completion” task in which they were presented with the first element of the NAD and had to choose the second element of the NAD to complete the stimuli. Our findings show that, despite large variability in the data, children aged 4–8 years are sensitive to NADs; they show the expected differences in r RTs in the SRT task and could transfer the NAD-rule in the Stem Completion task. We discuss these results with respect to the development of NAD dependency learning in childhood and the practical impact and limitations of collecting these data in a web-based setting
