Gender Choices of Conversational Agent: How Today’s Practice Can Shape Tomorrow’s Values
No full textWhen creating conversational agents, designers have to make decisions about the way the agents present themselves. In this position paper, we identify and synthesize ethical dilemmas that conversational interface designers and researchers face around gender of conversational agents. First, we identify three layers that cause tension in designing conversational agents’ gender: (i) interactional qualities; (ii) goal-orientation; and (iii) societal issues. We then argue that conversational agent designers and re- searchers can navigate this problem space by comparing two ethical frameworks: a utilitarian perspective and a dialogical ethics perspective. Finally, we argue that dialogical ethics can be a balanced, ethical lens that can help conversational agent designers and researchers make design decisions about the gender of an agentGreen Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Human-Centred Artificial IntelligenceHuman Information Communication DesignWeb Information System
Topologische Tegenvoorbeelden
No full textIn dit verslag bekijken we zes topologische tegenvoorbeelden. Eerst bestuderen we de topologie van Appert. Deze topologie is gedefinieerd op een aftelbare verzameling, maar heeft overaftelbaar veel open verzamelingen. In de ruimte van Appert zijn de triviale rijtjes de enige rijtjes die convergeren. De ruimte is separabel, maar voldoet niet aan het tweede aftelbaarheidsaxioma.Het is bekend dat elke aftelbare reguliere ruimte normaal is en dus `veel' continue functies naar het eenheidsinterval heeft. Daarom is een aftelbare reguliere ruimte niet samenhangend. Dit geldt echter niet voor aftelbare Hausdorff ruimten. We bestuderen een ruimte die aftelbaar Hausdorff is én samenhangend. Deze ruimte heet Gustin's rijruimte.Daarna bekijken we een andere samenhangende ruimte: de topologische sinus-kromme. Deze is niet compact, maar we kunnen de ruimte uitbreiden en er een compacte ruimte van maken. We zien in dit hoofdstuk dat niet elke kromme padsamenhangend is. Dus samenhang impliceert niet altijd padsamenhang.De vierde ruimte die we bestuderen is Van Douwen's ruimte. Deze is regulier en . Elke continue reëelwaardige functie in deze ruimte is constant.Verder bekijken we een overaftelbaar product van normale ruimten, waarvan de productruimte zelf niet normaal is. Of het product separabel is of niet, hangt af van de `grootte' van het product.Tot slot nog een productruimte: de ruimte van Helly. Dit product is wel normaal, maar bevat een niet-normale deelruimte. We zullen namelijk zien dat de ruimte compact Hausdorff is en een deelruimte heeft die homeomorf is met de Sorgenfreylijn. De ruimte voldoet aan het eerste maar niet aan tweede aftelbaarheidsaxioma. De ruimte is wel separabel.Applied Mathematic
Empirical differences between time mean speed and space mean speed
No full textInsight into traffic flow characteristics is often gained using local measurements. To determine macroscopic flow characteristics, time aggregation of microscopic information is required.Usually, a data collection system stores values averaged over time. However, it is well known that a time mean average overestimates the influence of faster vehicles, and consequently overestimates the mean speed. As a direct result, densities, computed from flow and speed, are underestimated.This paper compares the time mean speed and space mean speed, using data of individual car passages on a motorway road stretch. We show that the differences between time mean and space mean averages are substantial, up to a factor four. In particular in the lower speed regions the error is big. We indicate the considerable consequences for the jam density and shock wave speed. Finally, a fundamental diagram based on correctly averaged microscopic data can be fitted much better.Transport and Plannin
Weaving Stories:Toward Repertoires for Designing Things
Get PDFWhile much work is underway within the context of posthuman design, this research is often described from a dominantly human perspective. It rarely accounts for the creative capacities of nonhumans in design, such as materials, tools, and software. There is a need to further engage with posthuman theories conceptually, materially, and methodologically. We approach this challenge through Ron Wakkary's concept of repertoires: actions the human designer can take to increase participation of nonhumans in design research practice. This paper reports on potential repertoires' development by exploring three approaches from outside of HCI: describing the landscape, noticing, and translations. We use these methods to account for weaving events that the first author was engaged in. Through critical reflection of these accounts, we contribute three repertoires and an example of applying the theoretical framework of Designing Things.</p
Illumination Aesthetics
Get PDFRecent digital fabrication tools have enabled new form-giving using a wide range of physical materials. However, light as a first class creative material has been largely ignored within the design of our electronic objects. Our work expands the illumination design space by treating light as a physical material. We introduce a digital design tool that simulates and visualizes physical light interactions with a variety of materials for creating custom luminaires. We further develop a computational design and fabrication process for creating custom secondary optics elements (SOEs), which provides additional handles for users to physically shape and redirect light to compose, fill, and evenly diffuse planar and volumetric geometries. Through a workshop study with novice electronic designers, we show how incorporating physical techniques to shape light alters how users view the role and function of LEDs and electronics. We produce example pieces that showcase how our approach expands the electronics aesthetic and discuss how viewing light as material can engender novel, expressive artifacts.

Réflexions pour accroître l'attractivité des formations continues sur la qualité de vie au travail et les risques psychosociaux
No full textDie Herausforderungen des 21. Jahrhunderts bewirken sowohl im Bundesministerium der Finanzen BMF als auch im französischen Wirtschafts- und Finanzministerium MINEFI, der Gesunderhaltung der Beschäftigten besondere Aufmerksamkeit zu schenken. Beide Verwaltungen sehen dabei die Referatsleiter/innen (RL) in der Pflicht und bieten deshalb Fortbildungen im Gesundheitsmanagement an. Das Interesse der RL für dieses Angebot ist bisher gering. Die vorliegende Masterarbeit untersucht die Ursachen für das in der deutschen und französischen Finanzverwaltung unterschiedlich geringe Interesse und kommt zu dem Schluss, dass die Hemmnisse im MINEFI stärker durch soziokulturelle und institutionelle Faktoren (republikanische Elitenbildung und Positionsmacht der jeweiligen Hierarchiestufe) bedingt sind, während im BMF institutionelle und persönlichkeitsspezifische Gründe zusammentreffen. Die Behördenkultur beider Ministerien fokussiert die Arbeitsergebnisse der RL und lässt ihr Verhältnis zu den Referatsangehörigen weitestgehend außer Acht. Eine Attraktivitätssteigerung des Fortbildungsangebots im Gesundheitsmanagement setzt in beiden Verwaltungen voraus, Marketingstrategien innerhalb der Behörde zu etablieren, die die Wertigkeit des Gesundheitsmanagements im Organisationsgefüge erhöhen und dadurch die RL stärker motivieren. Dieser Change-Prozess erfordert Ausdauer und Geduld.Les défis du 21ème siècle nécessitent que le Ministère fédéral des Finances (BMF) et les Ministères économiques et financiers (MINEFI) se soucient de la santé et du bien-être de leurs employées. En conséquence, chacune des deux administrations souhaite instamment que les chefs de bureau se forment dans ce domaine qui jusqu'à présent éveille peu leur intérêt. Ce mémoire en recherche les causes. Il appert que prévalent aux MINEFI des raisons socioculturelles et institutionnelles (formation de l'élite républicaine et structure hiérarchique forte) tandis qu'au BMF coexistent des facteurs institutionnels et individuels. Les deux administrations sont écartelées entre la valorisation nécessaire de la production du chef de bureau et la prise en compte de son comportement envers ses subordonnés. Les deux ministères tireraient bénéfice d'une stratégie marketing interne fondée sur la qualité de vie au travail comme facteur-clé de l'organisation pour mieux motiver les chefs de bureau à participer à cette formation continue. Ce changement de paradigme demandera du temps et de la patience
Keep the VRhythm going:A musician-centred study investigating how Virtual Reality can support creative musical practice
Get PDFThe acoustic and visual experiences of musicians in the spaces they perform in are complex and organic in nature, entailing a continuous interaction with the environment. With this project, we leverage the power of Virtual Reality (VR) to support musicians in their creative practice by transporting them to novel sonic and visual worlds. For this, we developed a musician-centred VR system, featuring various acoustic and visual virtual environments, VR Rehearse & Perform, based on design requirements gathered with musicians and performance experts. To investigate how VR can be designed to support music-makers in their creative musical practice, we performed iterative tests with 19 musicians followed by semi-structured interviews. Our findings suggest that VR has the potential to support different aspects of the creative musical practice, such as rehearsing, performing and improvising. Our research provides insights and inspirations toward designing musician-centred VR experiences for various musical activities
