O presente estudo examina o trabalho interacional de resolução de problema em cenário de desenvolvimento tecnológico. Fundamentado na perspectiva teórico-metodológica da Análise da Conversa Etnometodológica, este trabalho busca produzir uma descrição situada da atividade interacional de resolução de problema e examinar em que medida essa atividade pode ser relacionada com momentos de construção conjunta de conhecimento. O corpus de análise se constitui de aproximadamente 60 horas de gravações audiovisuais geradas em um laboratório de tecnologia voltado à produção de materiais biomédicos. Nesta dissertação, são examinados em detalhe quatro segmentos de resolução de problema, representativos do conjunto de instâncias identificadas no corpus. Nos dados analisados, a atividade de resolução de problema é descrita enquanto instância interacional em que participantes lidam com (a) problemas que emergem como entraves ao andamento das atividades em curso, o que demanda deles (b) engajamento conjunto em busca de (c) uma resolução boa o suficiente para (d) a retomada da atividade em que vinham engajados quando o problema se instaurou. Em tal instância interacional, o surgimento de um problema a ser enfrentado pelos participantes acarreta, assim, (e) a suspensão da atividade que vinha sendo realizada, sendo (f) a sua resolução condição sine qua non para a retomada. O exame das instâncias levantadas permitiu identificar ainda que os participantes se engajam de maneiras distintas na resolução dos problemas que se colocam. Há ocorrências em que o problema a ser enfrentado constitui um obstáculo a ser transposto por todos os participantes envolvidos na interação. Nessas instâncias, não há ninguém que detém de antemão a resolução para a questão, que precisa, assim, ser conjuntamente buscada e negociada. Por outro lado, há também ocorrências em que o problema a ser enfrentado não constitui um obstáculo a ser transposto por todos os participantes. Nessas instâncias, a resolução para o problema é alcançada com a ajuda fornecida por um participante que, interacionalmente, coloca-se como mais experiente. Diante dos problemas e da necessidade iminente de resolvê-los, os participantes engajam-se no trabalho de construção conjunta de conhecimento, sendo essa construção observável nas ações que os próprios participantes realizam para os fins práticos de retomada das atividades que vinham realizando (ABELEDO, 2008; GARCEZ; SALIMEN, 2011). Na empreitada conjunta de resolução de problema, os participantes orientam-se para o problema a ser resolvido como objeto de conhecimento a ser alcançado. É, portanto, envidando esforços para a resolução dos problemas que os participantes constroem conhecimento com o outro. A investigação realizada oferece subsídios para a reflexão acerca de modos de organização e fomento da construção conjunta de conhecimento em cenário escolar pela implementação de uma proposta de trabalho organizada em torno de projetos que, à semelhança do que ocorre no cenário aqui investigado, levem os próprios alunos a construir conhecimento conjuntamente pela resolução conjunta de problemas práticos relacionados à sua execução. / The present study examines the interactional work of problem solving in a setting of technological development. Based on the theoretical and methodological perspective of Conversation Analysis, this study seeks to produce a situated description of the interactional activity of problem solving and examine to what extent this activity may be related to moments of joint construction of knowledge. The corpus of analysis is approximately 60 hours of audiovisual recordings generated at a lab dedicated to the development of technological innovation in biocompatible medical devices. In this text, we examine in detail four segments of problem solving, representing the set of instances identified in the corpus. In the data analyzed, the activity of problem solving is described as an interactional instance in which participants (a) deal with problems that emerge as barriers to the progress of ongoing activities, which requires them (b) joint engagement in search of (c) a solution that is good enough to (d) retake the activity in which they were engaged when the problem has emerged. In such interactional instance, the emergence of a problem to be faced by participants entails, thus, (e) the suspension of the activity that was being performed, and (f) its resolution as a prerequisite for the its resumption.The examination of these instances has also enabled the recognition that the participants engage in different ways when solving the problems that arise. There are instances in which the problem to be faced is an obstacle to be overcome by all participants involved in the interaction. In these instances, there is no one who knows beforehand the resolution to the problem, which must be then jointly pursued and negotiated. Conversely, there are also instances in which the problem to be faced is not an obstacle to be overcome by all participants. In these instances, the resolution to the problem is achieved with the help provided by a participant who stands as the most experienced. Considering the problems and the imminent need to solve them, participants engage in the work of the joint construction of knowledge, which is observable in the actions that the participants themselves perform for the practical purposes of the resumption of the activities that they were performing (ABELEDO, 2008; GARCEZ; SALIMEN, 2011). In the joint enterprise of problem solving, participants orient themselves to the problem to be solved as the object of knowledge to be attained. It is by making efforts to solve the problems that the participants produce knowledge with others. The research contributes for the reflection on modes of organization and promotion of joint construction of knowledge in school settings through the implementation of a pedagogy organized around projects that, similar to what occurs in the setting examined here, enable students to build knowledge together through the joint resolution of practical problems related to the implementation of the project.

The intention is to capture the assumptions and theoretical analysis of the situation of the company. The result should be a project which envisages the granting of subsidies.

Bei der Produktentwicklung von B2B-Produkten erhält das Nutzererleben (User Experience – UX) eine zunehmende Bedeutung (Lu & Roto 2015, Wölfel et al. 2016, Platz et al. 2018, Zeiner et al. 2018, Wölfel & Krzywinski 2019a, b). Dies gilt auch für die Angebote des Unternehmensbereichs Sicherheitstechnik von Dräger. Das Unternehmen entwickelt u. a. Produkte für die Feuerwehr, die chemische Industrie oder den Bergbau (Abbildungen 1 und 2). Das Ziel sind sicher, effizient und zufriedenstellend zu bedienende Produkte, Software und Services. Im Rahmen der kontinuierlichen Nutzer- und Kundenevaluation stellt sich eine gute Usability und User Experience als immer wichtiger werdende Anforderungen heraus, welche es zufriedenstellend zu erfüllen gilt. Sie haben zunehmend Einfluss auf die Kaufentscheidung von Anwendern und Kunden in der Sicherheitstechnik. Die Produkte heben sich nicht mehr allein durch ihre Funktionalität vom Wettbewerb ab. Um den nutzer- und kundenorientierten Anforderungen über den gesamten Produktlebenszyklus in Zukunft noch besser gerecht zu werden, wurden die aktuellen Prozesse analysiert und der Produktdesignprozess hin zu einem nutzerzentrierten UX-Design-Prozess reformiert. Dabei ist die Integration von UX Research und Design in die Produktentwicklung einer der wichtigsten Bestandteile.

This is an ethnographic case-study of research and development practices taking place in an interdisciplinary project between education and computer sciences. The Ensemble-project, part of the Technology Enhanced Learning programme (2008-12), has studied case-based learning in a number of diverse settings in Higher Education, working to develop semantic technologies for supporting that learning. Focussing on one of the six research settings, the discipline of archaeology, the current study has had three purposes. By opening up to scrutiny the practices of research and development, it has firstly sought to understand how a shared research question is answered in practice when divergent research approaches are brought to bear upon it. Secondly, the study has followed the emergence of a piece of semantic technology through these practices. The third aim has been to assess the advantages and disadvantages of Actor-Network Theory (ANT) in studying unfolding, open-ended processes in real time. Through critical ethnographic participation, multiple ethnographic research methods, and by drawing on ANT as theoretical practice, the study has shown the precarious and unpredictable nature of research and development work, the political nature of research methods and how multiple realities can be produced using them, and the need for technology development to flexibly respond to changing circumstances. We have also seen the mutual adoption and extension of practices by the two strands of the project into each others’ domains, and how interdisciplinary tensions resolved, while they did not disappear, through pragmatic changes within the project. The study contributes to the interdisciplinary fields of Science and Technology Studies (STS) where studies on the ‘soft sciences’, such as education, are few, and a new field of Studies in Social Science and Humanities (SSH) which is emerging alongside and from within the STS. Interdisciplinary endeavours between fields pertaining largely to the natural and the social sciences respectively have not been studied commonly within either field.

Modern Web or ¿Eternal-Beta¿ applications necessitate a flexible and easy-to-use data management platform that allows the evolutionary development of databases and applications. The classical approach of relational database systems following strictly the ACID properties has to be extended by an extensible and easy-to-use persistency layer with specialized DB features. Using the underlying concept of Software as a Service (SaaS) also enables an economic advantage based on the ¿economy of the scale¿, where application and system environments only need to be provided once but can be used by thousands of users. Within this tutorial, we are looking at the current state-of-the-art from different perspectives. We outline foundations and techniques to build database services based on the SaaS-paradigm. We discuss requirements from a programming perspective, show different dimensions in the context of consistency and reliability, and also describe different non-functional properties under the umbrella of Service-Level agreements (SLA).

Die Geräte, durch die Musik im Zeitalter der technischen (Re-)Produktion gehört wird, haben sich immer wieder gewandelt. Solche Geräte müssen überhört werden. Nur so kann Musik gehört werden. Trotzdem – so die These der Arbeit – organisieren diese Geräte das Hören und sind Agenturen einer Bewirtschaftung und Technisierung der Wahrnehmung. In der Arbeit wird anhand von zwei Fallstudien aus der Geschichte der Rock- und Popmusik gezeigt, wie solche Geräte sowohl den Hörer als auch die gehörte Musik formieren. Durch Hörtechnologien bilden sich neue Hörpraktiken heraus und die Körperlichkeit des Hörers wird neu bestimmt. Die Anpassung von Klanggeschehen an spezifische Hörtechnologien wird im Mastering – dem letzten Schritt der technischen Musikproduktion – untersuchbar. Die Geräte, durch die Musik gehört wird, sind also weder schlichte Wiedergabetechnologien noch bloße elektrotechnische Artefakte. Vielmehr sind sie Gefüge aus Klanglichkeit, Körperlichkeit und Technologie. Diese werden in der Arbeit als Hörgeräte auf den Begriff gebracht. Die Hörgeräte der Rock- und Popmusik zielen – wie ihre medizintechnischen Verwandten – auf die Materialität der Wahrnehmung. Im Gegensatz zu diesen funktionieren sie jedoch nicht als Prothesen, die an einer gattungsweit postulierten Norm ausgerichtet sind. Statt Normen bergen sie Exzesse – an Serialität und Wiederholung – sowie Eskalationen – von Lautstärke und von hohen und tiefen Frequenzen. Die Arbeit ist in drei Kapiteln gegliedert. Im ersten Kapitel wird die These der Arbeit in Bezug auf theoretische Diskurse der Musik-, Kultur- und Medienwissenschaft verortet und eine begriffliche Systematik entwickelt. Kapitel zwei und drei sind Fallstudien gewidmet. In der ersten wird das Jukeboxhören der Rock’n’Roll-Kultur der 1950er Jahre untersucht, in der zweiten das Soundsystemhören der Disco- und Clubkultur der 1970er bis 1990er Jahre. Die im ersten Kapitel entwickelte begriffliche Systematik macht die Fallstudien vergleichbar. / The devices by which music is listened to in the age of technological (re-)production have changed over and over again. These devices must be imperceptible to the ear. Only then can music be heard. Nonetheless – this is the claim of the thesis – these devices organize hearing and are agents of a cultivation and technization of perception. Based on two case studies from the history of rock and pop music, this thesis reveals how such devices constitute not only the listener but also the music which is listened to. Through listening technologies new listening practices emerge and the corporality of the listener is newly defined. The adaptation of sound to specific listening technologies can be analysed during the mastering process, the last step in technological music production. The devices by which music is listened to are thus neither simple technologies of reproduction nor mere electrotechnical artefacts. Rather, they are assemblages of sound, corporality, and technology. In this thesis these assemblages are called “Hörgeräte” (listening devices). The listening devices of rock and pop music target – like medical-technical “Hörgeräte” (hearing aids) – the materiality of perception. Contrary to medical technologies, however, listening devices do not function as prostheses, which are calibrated according to medical industry standards. Instead, they contain excesses – of seriality and repetition – and escalations – of amplitude and high and low frequencies. The thesis is arranged in three chapters. In the first chapter I situate the main argument of the thesis within discourses of musicology, media and cultural studies, and develop my own terminology. Chapters two and three deal with case studies. In chapter two I investigate jukebox listening in 1950s rock’n’roll culture, whilst in chapter three I explore sound system listening in disco and club culture from the 1970s to the 1990s. The terminology developed in chapter one enables a comparison of the case studies.
