    Virtual Speech Reading Support for Hard of Hearing in a Domestic Multi-Media Setting2009Ingår i: INTERSPEECH 2009: 10TH ANNUAL CONFERENCE OF THE INTERNATIONAL SPEECH COMMUNICATION ASSOCIATION 2009, BAIXAS: ISCA-INST SPEECH COMMUNICATION ASSOC , 2009, s. 1443-1446Konferensbidrag (Refereegranskat)
    Abstract [en]

    In this paper we present recent results on the development of the SynFace lip synchronized talking head towards multilinguality, varying signal conditions and noise robustness in the Hearing at Home project. We then describe the large scale hearing impaired user studies carried out for three languages. The user tests focus on measuring the gain in Speech Reception Threshold in Noise when using SynFace, and on measuring the effort scaling when using SynFace by hearing impaired people. Preliminary analysis of the results does not show significant gain in SRT or in effort scaling. But looking at inter-subject variability, it is clear that many subjects benefit from SynFace especially with speech with stereo babble noise.

    The MUMIN coding scheme for the annotation of feedback, turn management and sequencing phenomena2007Ingår i: Language resources and evaluation, ISSN 1574-020X, E-ISSN 1574-0218, Vol. 41, nr 3-4, s. 273-287Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper deals with a multimodal annotation scheme dedicated to the study of gestures in interpersonal communication, with particular regard to the role played by multimodal expressions for feedback, turn management and sequencing. The scheme has been developed under the framework of the MUMIN network and tested on the analysis of multimodal behaviour in short video clips in Swedish, Finnish and Danish. The preliminary results obtained in these studies show that the reliability of the categories defined in the scheme is acceptable, and that the scheme as a whole constitutes a versatile analysis tool for the study of multimodal communication behaviour.

    Information Coordination Using Meta-agents in Information Logistics Processes2008Ingår i: Proceedings of Knowledge-Based and Intelligent Information & Engineering Systems: KES2008 / [ed] Ignac Lovrek, Robert J. Howlett, Lakhmi C. Jain, Berlin Heidelberg: Springer Berlin/Heidelberg, 2008, s. 788-798Konferensbidrag (Refereegranskat)
    Abstract [en]

    In order to coordinate and deliver information in the right time and to the right place, theories from multi-agent systems and information logistics are combined. We use agents to support supply chain by searching for company specific information. Hence, there are a vast number of agents working at the Internet, simultaneously, which requires supervising agents. In this paper, we suggest using meta-agents to control the behaviour of a number of intelligent agents, where the meta-agents are working with coordination of the communication that takes place in a supply chain system. As an example, we look at a manufacturing company receiving orders on items from customers, which need to be produced. The handling of this distributed information flow can be thought of as an Information Logistics Processes and the similarities of the functioning of processes and intelligent agents’ behaviour are illuminated.

    A Security Architecture for 5G Networks2018Ingår i: IEEE Access, E-ISSN 2169-3536, Vol. 6, s. 22466-22479Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    5G networks will provide opportunities for the creation of new services, for new business models, and for new players to enter the mobile market. The networks will support efficient and cost-effective launch of a multitude of services, tailored for different vertical markets having varying service and security requirements, and involving a large number of actors. Key technology concepts are network slicing and network softwarization, including network function virtualization and software-defined networking. The presented security architecture builds upon concepts from the 3G and 4G security architectures but extends and enhances them to cover the new 5G environment. It comprises a toolbox for security relevant modeling of the systems, a set of security design principles, and a set of security functions and mechanisms to implement the security controls needed to achieve stated security objectives. In a smart city use case setting, we illustrate its utility; we examine the high-level security aspects stemming from the deployment of a large number of IoT devices and network softwarization.

    Designed by Engineers: An analysis of interactionaries with engineering students2015Ingår i: Designs for Learning, ISSN 1654-7608, Vol. 7, nr 2, s. 28-56, artikel-id 10.2478/dfl-2014-0062Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The aim of this study is to describe and analyze learning taking place in a collaborative design exercise involving engineering students. The students perform a time-constrained, open-ended, complex interaction design task, an “interactionary”. A multimodal learning perspective is used. We have performed detailed analyses of video recordings of the engineering students, including classifying aspects of interaction. Our results show that the engineering students carry out and articulate their design work using a technology-centred approach and focus more on the function of their designs than on aspects of interaction. The engineering students mainly make use of ephemeral communication strategies (gestures and speech) rather than sketching in physical materials. We conclude that the interactionary may be an educational format that can help engineering students learn the messiness of design work. We further identify several constraints to the engineering students’ design learning and propose useful interventions that a teacher could make during an interactionary. We especially emphasize interventions that help engineering students retain aspects of human-centered design throughout the design process. This study partially replicates a previous study which involved interaction design students.

    Företagskulturers makt: överbrygga språkliga klyftor2008Licentiatavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    How do we work in projects that are expected to bridge cultural, social and historical boundaries? Is it possible to apply stated instructions across these boundaries so that, for example, the task of producing a requirement specification is interpreted in the same way by all the parties involved?

    In this thesis, the author takes a stand against his personal experience from such a trans-cultural project – a project in which he failed. A factor that made a strong contribution to this failure was the inability of the companies involved to manage the underlying complex of problems, problems associated with the philosophy of language. They possessed neither the knowledge nor the instruments to bridge the chasms of language. Essential reflection and analysis was replaced by the power language of the enterprise; individuals were singled out and held responsible, and the failure was relegated by definition to the level of personal issues.

    Experience does not automatically become knowledge; this is a process that requires reflection.

    The author suggests a number of ways of tackling communications problems among people who not only do not understand one another, but do not understand that they do not understand. The latter may mean that two people think that something is unambiguous, yet their interpretations diverge. This is when problems occur. Nobody has made a mistake – both parties have acted properly, they have even (perhaps) talked the matter through and reached agreement, yet the result still does not coincide with what they anticipated.

    A central concept is dialogue. Through its organised form, dialogue can make openings in problems that cut through cultural, social and historical boundaries. It is an approach that may be illustrated through authors and philosophers such as Witold Gombrowicz, Ludwik Fleck, Oscar Wilde, Joseph Conrad and Galileo Galilei.

    This study has its basis and its origins in the research area of Skills and Technology at the Royal Institute of Technology, Stockholm (KTH).

    Quantifying leadership in climate negotiations: A social power game2023Ingår i: PNAS Nexus, E-ISSN 2752-6542, Vol. 2, nr 11, artikel-id pgad365Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We consider complex multistage multiagent negotiation processes such as those occurring at climate conferences and ask ourselves how can an agent maximize its social power, intended as influence over the outcome of the negotiation. This question can be framed as a strategic game played over an opinion dynamics model, in which the action of an agent consists in stubbornly defending its own opinion. We show that for consensus-seeking opinion dynamics models in which the interaction weights are uniform, the optimal action obeys to an early mover advantage principle, i.e. the agents behaving stubbornly in the early phases of the negotiations achieve the highest social power. When looking at data collected from the climate change negotiations going on at the United Nations Framework Convention on Climate Change, we find evidence of the use of the early mover strategy. Furthermore, we show that the social powers computed through our model correlate very well with the perceived leadership roles assessed through independent survey data, especially when non-uniform weights incorporating economical and demographic factors are considered.

    Visual correlates to prominence in several expressive modes2006Ingår i: INTERSPEECH 2006 AND 9TH INTERNATIONAL CONFERENCE ON SPOKEN LANGUAGE PROCESSING, BAIXAS: ISCA-INST SPEECH COMMUNICATION ASSOC , 2006, s. 1272-1275Konferensbidrag (Refereegranskat)
    Abstract [en]

    In this paper, we present measurements of visual, facial parameters obtained from a speech corpus consisting of short, read utterances in which focal accent was systematically varied. The utterances were recorded in a variety of expressive modes including certain, confirming, questioning, uncertain, happy, angry and neutral. Results showed that in all expressive modes, words with focal accent are accompanied by a greater variation of the facial parameters than are words in non-focal positions. Moreover, interesting differences between the expressions in terms of different parameters were found.

    Hearing at Home: Communication support in home environments for hearing impaired persons2008Ingår i: INTERSPEECH 2008: 9TH ANNUAL CONFERENCE OF THE INTERNATIONAL SPEECH COMMUNICATION ASSOCIATION 2008, BAIXAS: ISCA-INST SPEECH COMMUNICATION ASSOC , 2008, s. 2203-2206Konferensbidrag (Refereegranskat)
    Abstract [en]

    The Hearing at Home (HaH) project focuses on the needs of hearing-impaired people in home environments. The project is researching and developing an innovative media-center solution for hearing support, with several integrated features that support perception of speech and audio, such as individual loudness amplification, noise reduction, audio classification and event detection, and the possibility to display an animated talking head providing real-time speechreading support. In this paper we provide a brief project overview and then describe some recent results related to the audio classifier and the talking head. As the talking head expects clean speech input, an audio classifier has been developed for the task of classifying audio signals as clean speech, speech in noise or other. The mean accuracy of the classifier was 82%. The talking head (based on technology from the SynFace project) has been adapted for German, and a small speech-in-noise intelligibility experiment was conducted where sentence recognition rates increased from 3% to 17% when the talking head was present.

    Risk, language and discourse2016Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [sv]

    Avhandlingen analyserar begreppet risk och hur detta begrepp strukturerar diskurs. Ett centralt intresse för analysen är faktisk språkanvändning.

              I den första artikeln analyseras de engelska begreppen risk, safety and security och deras relation. Analysen bygger på korpusdata (the Corpus of Contemporary American English). Lexikala och grammatiska kontexter för substantiven risk, safety och security och adjektiven risky, safe och secure analyseras och jämförs. Både likheter och skillnader identifieras vilka i stort bekräftar att safety (safe) och security (secure) är synonymer och i sin tur motsatser (antonymer) till risk (risky). Studien stödjer flera tidigare antaganden om dessa begrepp inom forskningslitteraturen, men motsäger andra.

              I den andra artikeln analyseras de engelska begreppen risk och danger och deras relation baserat på korpusdata (the British National Corpus). Ramsemantik (eng. frame semantics) används för att undersöka antagandet att begreppet risk förutsätter beslutsfattande, medan begreppet danger inte gör det. Studien stödjer delvis detta antagande, men visar också på problem med antagandet.

              I den tredje artikeln analyseras hur nyhetspress framställer risk och orsak-verkansamband (kausalitet). Två teorier används. För det första används teorin om medias ”inramning” av händelser (eng. media framing). För det andra används filosofiska perspektiv på kausala beskrivningar. En huvudsaklig slutsats är att risker framställs på många olika sätt med avseende på kausalitet. Exempelvis kan en och samma risk framställas som ett resultat av flera olika orsaker. Vidare framställer nyhetspress riskers kausalitet med olika grader av komplexitet. I vissa tidningsartiklar presenteras risker utan några kausala förklaringar. I andra tidningsartiklar presenteras risker som resultat av komplexa orsak-verkansamband. Om man betraktar nyhetsrapporteringen om risker på en övergripande nivå, så framträder en komplex bild av riskers orsakssamband.

              I den fjärde artikeln analyseras framställningar av fenomen som benämns med morfemet nano, exempelvis nanoteknologi, nanomaterial och nanorobotar. Frågan som besvaras är på vilket sätt sådana fenomen framställs som risker i svensk nyhetspress. Teoretiskt utgår studien från den relationella teorin om risk och ramsemantik. Baserat på vilka fenomen som framställs som riskobjekt (eller hot) i tidningsartiklar, identifieras fem grupper av nanorisker: (I) nanoteknologi, (II) nanoteknologi och dess produkter (t.ex. nanopartiklar och nanomaterial), (III) nanopartiklar (utan referens till nanoteknologi), (IV) nanopartiklar som inte är resultat av nanoteknologi (utan istället uppstår t.ex. i trafiken) och (V) nanoteknologi och nanorobotar. För varje grupp undersöks vidare mönster i framställningen av dessa risker, exempelvis, vad som beskrivs som hotat av dessa riskobjekt och under vilka förutsättningar. Studiens empiriska observationer stödjer tidigare forskning om hur nanorisker rapporteras i nyhetspress internationalt. Rapporteringen av nanorisker är influerad av vetenskapliga riskbedömningar, men också av science fiction.

              I den femte artikeln analyseras en kontrovers kring användningen av antibakteriellt silver inom sjukvården och i konsumentartiklar som exempelvis träningskläder och sportutrustning. Fokus för artikeln är hur risker uppfattas i den svenska debatten som inbegriper nyhetsmedia (press och TV), regering och riksdag, myndigheter, kommuner, intresseorganisationer och företag. Vissa aktörer menar att silver är ett riskobjekt som påverkar olika värden på ett negativt sätt, till exempel, folkhälsan, miljön, och avloppsreningsindustrin. Andra aktörer förnekar dessa påståenden. De menar till och med att silver har fördelar som att motverka risker som hotar folkhälsan och miljön. Med andra ord åberopar båda sidorna av kontroversen hälsa och miljö som värden viktiga att skydda. Slutligen identifieras tre strategier för riskkommunikation som tillämpas i kontroversen: (i) framställningen av silver som en miljö- och hälsorisk, (ii) förnekande av dessa påståenden, och (iii) nyttoassociationer där silver framställs som något som motverkar miljö- och hälsorisker.

    Are computers the solution to support development in children in need of special support?2004Ingår i: Technology and Disability, ISSN 1055-4181, E-ISSN 1878-643X, Vol. 16, nr 3, s. 137-145Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This article is based on several studies conducted in the ICT field focussing on children with severe disabilities and their computer use. Topics of interest include how computers are used by children in general, and especially by children with severe disabilities. How effective is technology as support for child development and in daily activities? The main focus is on play and communication/social interaction for child development. The key question is if and how computers are the solution to support development in children in need of special support.

    Meetings, practice and beyond: Environmental sustainability in meeting practices at work2013Ingår i: Nachhaltigkeit in der Wirtschaftskommunikation / [ed] Martin Nielsen, Iris Rittenhofer, Marianne Grove Ditlevsen, Sophie Esmann Andersen, Irene Pollach, Wiesbaden: Springer Fachmedien Wiesbaden , 2013, s. 159-190Kapitel i bok, del av antologi (Refereegranskat)
    Abstract [en]

    The study shows how the employees at a large transnational telecom company understand and accommodate the implemented travel and meeting policies that regulate business communication. This involves looking at employee decisions on when, how and why to hold meetings. The subsequent understandings of meetings and their practice is formed through negotiation and the formation of a ‘social matrix of workplace communication (meetings)’(Bateson & Reusch 2009). This social matrix and its contexts are analysed from the perspective of environmental sustainability of office work practice. The basis for this is the recent implementation of company-wide restrictions on travel aiming to encourage the use of mediated meetings instead of travel for face-to-face meetings. Some issues that emerge are shared meanings of meetings, more specifically the perceived importance of the physical meeting in a workplace where telephone meetings were the norm. This shows that even if the technological possibilities for mediated meetings and by extension a more flexible work practice exist, they are not regarded as default but seen as complementary to conventional work practices. The need to find a balance in between mediated and physical meetings comes across as a recurring theme in both interviews and policy documents.  As a result the ongoing negotiation of which meetings are deemed necessary to be held in person and thereby requiring travel, is embedded within TeliaSonera employees' notions that face-to-face meetings are better and more efficient than mediated meetings. Subsequently the collective view that mediated meetings are not as successful as face-to-face meetings becomes a central to the character of workplace communication. This negotiation is carried out on an individual level as well as on a more organisational level. When carried out on an organisational level these negotiations occur in policy documents which can sometimes contradict employee perspectives and are equally subject to contextual factors (cf. Kogg 2002). Other related issues present in the empirical data are the blurring of the divide between work and home in relation to the changes in work practices and information and communication technology (ICT).

    From Maps to Apps: Tracing the Organizational Responsiveness of an Early Multi-Modal Travel Planning Service2015Ingår i: The Journal of urban technology, ISSN 1063-0732, E-ISSN 1466-1853, Vol. 22, nr 4, s. 87-101Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    An Internet-based system for informing on multimodal travel planning (several modes of transportation) was introduced in Stockholm, Sweden in October 2000 in the form of a web page called trafiken.nu. The web page has a historical value of being one of the first attempts in Europe, and possibly the world, at providing an ICT-based travel planning service geared towards facilitating sustainable travel to the general public. The aim of this article is to investigate the historical development of trafiken.nu in order to draw lessons on how to better provide for a public information service with a potential for facilitating sustainable travel planning. Findings from the study of trafiken.nu suggest that the organizations behind the service have been slow in adapting to shifting media technology practices on how to provide for information which has affected the uptake of the service. Lessons from the case study provide a basis for arguing that organizations attempting to implement public information services would benefit from finding a means of harnessing collective intelligence in order to provide for a more customizable and responsive service to the general public.

    From Vision to Transition: Exploring the Potential for Public Information Services to Facilitate Sustainable Urban Transport2014Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Background: Policy initiatives to promote sustainable travel through the use of Internet based public information systems have increased during the last decade. Stockholm, in being one of the first cities in Europe to implement an Internet based service for facilitating sustainable travel is believed to be a good candidate for an analysis of key issues for developing sustainable travel planning services to the public.

    Aim: This thesis investigates the past development of two Stockholm based public information systems and their services in order to draw lessons on how to better provide for a public information service geared towards facilitating  environmentally sustainable travel planning through information and communications technology. The overall goal of the thesis is to contribute to an understanding on how to better design and manage current and future attempts at facilitating sustainable travel planning services based on historical case studies.

    Approach: The thesis draws ideas from the concept of organizational responsiveness – an organization’s ability to listen, understand and respond to demands put to it by its internal and external stakeholders – in order to depict how well or not the two public information systems and their owners have adapted to established norms and values of their surroundings.

    Results: Overall, the findings from the historical case studies suggest that organizations attempting to provide sustainable travel planning to the public need to design and manage their systems in such a way that it responds to shifting demands on how to provide for information. Implementing and embedding new technologies involves complex processes of change both at the micro level – for users and practitioners of the service – and at the meso level for the involved public service organizations themselves. This condition requires a contextualist framework to analyze and understand organizational, contextual and cultural issues involved in the adoption of new technologies and procedures.

    Conclusions: The thesis concludes with a discussion on how the findings from the historical case studies may provide lessons for both current and future attempts at providing public information systems geared towards facilitating environmentally sustainable travel planning to the public. Historical examples and issues concerning collective intelligence and peer to peer based forms of designing, producing and supervising public information services identified throughout the study are looked upon and discussed in terms of their possible role in increasing the potential for public information services to facilitate sustainable urban transport.

    Cross-Cultural Perception of Discourse Phenomena2009Ingår i: INTERSPEECH 2009: 10TH ANNUAL CONFERENCE OF THE INTERNATIONAL SPEECH COMMUNICATION ASSOCIATION 2009, BAIXAS: ISCA-INST SPEECH COMMUNICATION ASSOC , 2009, s. 1723-1726Konferensbidrag (Refereegranskat)
    Abstract [en]

    We discuss perception studies of two low level indicators of discourse phenomena by Swedish. Japanese, and Chinese native speakers. Subjects were asked to identify upcoming prosodic boundaries and disfluencies in Swedish spontaneous speech. We hypothesize that speakers of prosodically unrelated languages should be less able to predict upcoming phrase boundaries but potentially better able to identify disfluencies, since indicators of disfluency are more likely to depend upon lexical, as well as acoustic information. However, surprisingly, we found that both phenomena were fairly well recognized by native and non-native speakers, with, however, some possible interference from word tones for the Chinese subjects.

    Scenario modelling for the Divertor Tokamak Test facility2022Ingår i: NUOVO CIMENTO C-COLLOQUIA AND COMMUNICATIONS IN PHYSICS, ISSN 2037-4909, Vol. 45, nr 6, artikel-id 162Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The scenario integrated modelling is a top priority work during the design of a new tokamak, as the Divertor Tokamak Test facility (DTT) under construction at the ENEA Research Center in Frascati. The first simulations of the main baseline scenarios contributed to the optimization of the DTT project, particularly with regard to the machine size and heating systems, besides serving as reference for diagnostics design. In this paper we report the first simulations of the full power baseline scenario in the final configuration of the machine and heating mix.

    The internet at the eco-village: Performing sustainbility in the twenty-first century2016Ingår i: First Monday, E-ISSN 1396-0466, Vol. 21, nr 5Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Is the digital infrastructure and its footprint an ideological blind spot for recently emerging ecological communities, including eco-villages? This paper examines how a group of people who are concerned with environmental issues such as peak oil and climate change are orchestrating a transition toward a more sustainable and resilient way of living. We studied a Swedish eco-village, considering how computing in this community contributes to defining what alternative ways of living might look like in the twenty-first century. Drawing on a social-ecological perspective, the analysis illustrates, on the one hand, that the Internet, along with the digital devices we use to access it, capitalizes and mobilizes values, knowledge and social relationships that in turn enhance resilience in the eco-village. On the other hand, the analysis shows that an explicit focus on ecological values is not sufficient for a community of individuals to significantly transform Internet use to conform to ecological ideals. This work contributes to a deeper understanding of the imbrication of social technologies with practices that are oriented to perform sustainable and resilient ways of living.

    Complicit surveillance, interveillance, and the question of cosmopolitanism: Toward a phenomenological understanding of mediatization2015Ingår i: New Media and Society, ISSN 1461-4448, E-ISSN 1461-7315, Vol. 17, nr 9, s. 1473-1491Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The institutional and meta-processual dimensions of surveillance have been scrutinized extensively in literature. In these accounts, the subjective, individual level has often been invoked in relation to subject-object, surveillor-surveilled dualities and in terms of the kinds of subjectivity modern and late-modern institutions engender. The experiential, ontological realm of the mediatized everyday vis-a-vis surveillance remains less explored, particularly from the phenomenological perspective of the lifeworld. Academic discourses of surveillance mostly address rhetorically oriented macro-perspectives. The same diagnosis largely applies to the debates on the cosmopolitanization process. The literature of cosmopolitanism revolves around broad cultural and ethical transformations in terms of the relationship between Self and Other, individual and humanity, and the local and the universal. Our aim in this article is to conceptualize the dynamics that yield a cosmopolitan Self and an encapsulated Self under conditions of increasingly interactive and ubiquitous forms of mediation and surveillance.

    Abstract [en]

    The seminal 1983 "Ferments in the Field" collection made limited reference to environmental issues and concerns. Considering communication media and technological artifacts as both nature and culture and, more specifically, through defining media as both infrastructural environments and content, we discuss how challenges brought about by environmental change can inform contemporary media and communication research and environmental communication. The materiality of e-waste, which has resonance for cultural, political, economic, and geographic analyses, is used as an illuminating case in point. We link the implications ensuing from the e-waste issue with the roles mediation and communication of environmental narratives play, and how they can be informed by such "medianatures," as well as geopolitical considerations.

    Gestures in Performance2010Ingår i: Musical Gestures: Sound, Movement, and Meaning, Taylor and Francis , 2010, s. 36-68Kapitel i bok, del av antologi (Övrigt vetenskapligt)
    Abstract [en]

    On occasion, one can observe a whole orchestra section moving and playing in unison. In such an instance, all violinists play the melody using the same type of bowing movements and lean forward in unison at a given time during a specific passage in the music. Thus, not only do the musicians use very similar movements to produce the same notes but they sometimes also coordinate bodily sways or other movements with the other players. The musical gesture seems to manifest itself in both sound and movement. Whether we are watching as audience, or participating and interacting in the actual performance itself, we receive a considerable amount of gestural information. The aim of this chapter is to give examples of gestures that may be observed during performance, and to consider the kind of information they might convey, either to other performers or to the audience.

    A Modern Trial: A Study of the Use of Video-Recorded Testimonies in the Swedish Court of Appeal2013Ingår i: Studies in Law, Politics, and Society, ISSN 1059-4337, Vol. 61, s. 81-135Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The essay studies the introduction and use of audio-visual media in contemporary Swedish courtroom praxis and how this affects social interaction and the constitution of judicial space. The background to the study is the increasing use of video technology in law courts during the last decennium, and in particular the reformed trial code regulating court proceedings introduced in Sweden in 2008. The reform is called A Modern Trial (En modernare raättegång, Proposition 2004/05:131). An important innovation is that testimonies in lower level court proceedings now are video recorded and, in case of an appeal trial, then are screened in the appellate court. The study of social interaction and the constitution of judicial space in the essay is based in part on an ethnographic study of the Stockholm appellate court(Svea hovraätt) conducted in the fall 2010; in part on a study of the preparatory works to the legal reform; and in part on research on how media technology affects social interaction and the constitution of space and place.

    ”Hope Dies – Action Begins”: Civil olydnad och fredlig direkt aktion inom svensk klimataktivism – exemplet Extinction Rebellion2023Ingår i: K & K: kultur og klasse : kritik og kulturanalyse, ISSN 0905-6998, E-ISSN 2246-2589, nr 134-135, s. 129-157Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The article explores the use of civil disobedience and non-violent direct action (NVDA) as a strategy and method in climate activism in Sweden, with a particular focus on the group Extinction Rebellion (XR). The article describes and analyzes a number of XR actions carried out in 2019-2022, with a focus on meaning-making practices. The uses of civil disobedience and NVDA are presented within a historical, cultural and social context; the question of the role and legitimacy of civil disobedience in democratic societies is discussed. 

    XR has civil disobedience and NVDA as central strategy and in this way the group has put these protest methods in focus, and after each major action there is a need to both explain and justify their use. This is more noticeable in a Swedish cultural context that is characterized by consensus and a stigmatization of disobedience. This relationship in turn affects the planning and execution of disobedient and disruptive protest actions in Sweden. The article explores how activists in XR Sweden relate to this specific cultural context and how they try to influence it; hence XR Sweden works not only to influence those in power and public opinion regarding the climate crisis, but also on the possibilities and forms of civil political protests. 

    The article is based on participant observation. These began in the spring of 2019 and are still ongoing. The study has an anthropological perspective, with an emphasis on semiotics and hermeneutics.

    "Look at the happy bear here!": The use of artivism in Extinction Rebellion Sweden2023Ingår i: Journal of Resistance Studies, ISSN 2001-9947, Vol. 9, nr 2, s. 40-77Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The article describes and analyses how the climate activist group Extinction Rebellion (XR) Sweden makes use of art as part of nonviolent direct actions, a form of action which often is referred to as artivism. The article is based on direct observations of actions, documented online chats, interviews with participants, and content analysis of films, photographs and social media posts. The artivist actions were performed in Stockholm in 2020-2022. The interviews were made in the autumn 2022. The first part of the article is descriptive, presenting a series of artivist actions performed by the XR group. There is also a critical and historical discussion of politically engaged art and the use of art in activism. The second part of the article consists of a thematic analysis of the interview material. The article argues that artivism is import- ant both as a means of communication and for the internal culture in the activist group. As a form of meaning-making, artistic creation challenges the ready-made framing of political issues. The artivist performance is a form of place-making, temporarily transforming the meaning of public space, set- ting the stage for a carnivalesque where climate activists can appear as Fossil Fuel Industry executives, openly revealing disinformation and Greenwashing campaigns. Artivist action constitutes a form of aesthetics of resistance, chal- lenging hegemonic ideological representation. Many of the artivist actions performed by the XR group were satirical, where humour plays an important part. Humour is also important in other ways, to keep up the spirit and en- gagement of the activists, and to defuse possible tension with bystanders and representatives of law enforcement.

    The Language of Late Fossil Capital2023Ingår i: Nordic Journal of Media Studies, E-ISSN 2003-184X, Vol. 5, nr 1, s. 172-193Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This essay studies the propaganda language of contemporary – or late – fossil capital. Whereas the traditional understanding of propaganda focuses on the dissemination of information (or disinformation) in order to promote a political cause or ideology, I argue that the main form and vehicle of propaganda for late fossil capital is the massive use of terms and tropes, together with particular rhetorical devices, for example, the interpellation of the individual consumer as responsible for mitigating climate change. The essay studies the language of fossil capital based primarily on marketing material by fossil fuel companies, in the US and other Western countries, such as advertising and advertorials, current and archived websites, social media, corporate sustainability reports, as well as material produced by industry organisation such as the American Petroleum Institute and the Heartland Institute. A large part of the material is taken from two North American legal complaints, Connecticut v. Exxon Mobil Corporation (2020) and City of New York v. Exxon Mobil Corp. et al. (2021).

    Scalable Capacity Bounding Models for Wireless Networks2016Ingår i: IEEE Transactions on Information Theory, ISSN 0018-9448, E-ISSN 1557-9654, Vol. 62, nr 1, s. 208-229Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The framework of network equivalence theory developed by Koetter et al. introduces a notion of channel emulation to construct noiseless networks as upper (respectively, lower) bounding models, which can be used to calculate the outer (respectively, inner) bounds for the capacity region of the original noisy network. Based on the network equivalence framework, this paper presents scalable upper and lower bounding models for wireless networks with potentially many nodes. A channel decoupling method is proposed to decompose wireless networks into decoupled multiple-access channels and broadcast channels. The upper bounding model, consisting of only point-to-point bit pipes, is constructed by first extending the one-shot upper bounding models developed by Calmon et al. and then integrating them with network equivalence tools. The lower bounding model, consisting of both point-to-point and point-to-points bit pipes, is constructed based on a two-step update of the lower bounding models to incorporate the broadcast nature of wireless transmission. The main advantages of the proposed methods are their simplicity and the fact that they can be extended easily to large networks with a complexity that grows linearly with the number of nodes. It is demonstrated that the resulting upper and lower bounds can approach the capacity in some setups.

    Abstract [en]

    It has long been noted that conversational partners tend to exhibit increasingly similar pitch, intensity, and timing behavior over the course of a conversation. However, the metrics developed to measure this similarity to date have generally failed to capture the dynamic temporal aspects of this process. In this paper, we propose new approaches to measuring interlocutor similarity in spoken dialogue. We define similarity in terms of convergence and synchrony and propose approaches to capture these, illustrating our techniques on gap and pause production in Swedish spontaneous dialogues.

    A bottom-up strategy for establishment of EER in three Nordic countries – the role of networks2018Ingår i: European Journal of Engineering Education, ISSN 0304-3797, E-ISSN 1469-5898, Vol. 43, nr 2, s. 219-234Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper investigates the emergence of an engineering education research (EER) community in three Nordic countries: Denmark, Finland and Sweden. First, an overview of the current state of Nordic EER authorship is produced through statistics on international publication. Then, the history of EER and its precursor activities is described in three national narratives. These national storylines are tied together in a description of recent networking activities, aiming to strengthen the EER communities on the Nordic level. Taking these three perspectives together, and drawing on concepts from community of practice theory, network theory and learning network theory, we discuss factors behind the differences in the countries, and draw some conclusions about implications for networking activities in a heterogeneous community. Further, we discuss the role of networks for affording a joint identity.

    Are real tongue movements easier to speech read than synthesized?2009Ingår i: INTERSPEECH 2009: 10TH ANNUAL CONFERENCE OF THE INTERNATIONAL SPEECH COMMUNICATION ASSOCIATION 2009, BAIXAS: ISCA-INST SPEECH COMMUNICATION ASSOC , 2009, s. 824-827Konferensbidrag (Refereegranskat)
    Abstract [en]

    Speech perception studies with augmented reality displays in talking heads have shown that tongue reading abilities are weak initially, but that subjects become able to extract some information from intra-oral visualizations after a short training session. In this study, we investigate how the nature of the tongue movements influences the results, by comparing synthetic rule-based and actual, measured movements. The subjects were significantly better at perceiving sentences accompanied by real movements, indicating that the current coarticulation model developed for facial movements is not optimal for the tongue.

    The Case for Play in the Developing World: Lessons from Rah Island, Vanuatu2015Ingår i: Indigenous People and Mobile Technologies / [ed] Laurel Evelyn Dyson, Stephen Grant, Max Hendriks, Routledge, 2015Kapitel i bok, del av antologi (Övrigt vetenskapligt)
    Abstract [en]

    This chapter investigates the potential of mobile technologies for Indigenous empowerment in the context of the Sami community, based on the example of an application for mobile devices that reveals a Sami linguistic landscape via augmented reality. Mobile technology is reshaping not only the media landscape, but also the way people can interact with the environmental landscape. The mobility is approached not only in terms of technological accessibility but also as a practice, i.e., in relation to uses and representations of place, space, and landscape. The potential of linguistic landscapes is emphasized in the problematization and investigation of the effects of public signs on language behaviour. Indigenous linguistic landscapes can contribute to ethnolinguistic vitality and to the strengthening of identity. The mobility of mobile technology can indeed reinforce the sense of place because it can function as a form of digital cartography and place-specific knowledge.

    Distortion measures for vector quantization of noisy spectrum2005Ingår i: Eur. Conf. Speech Commun. Technol., 2005, s. 3173-3176Konferensbidrag (Refereegranskat)
    Abstract [en]

    In this paper we address the problem of vector quantization of speech in a noisy environment. We show that the performance of a vector quantization system can be improved by adapting the distortion measure to the changing environmental conditions. The proposed method emphasizes the distortion in spectral regions where the speech signal dominates. The method functions well even when conventional pre-processor methods fail because the noise statistics cannot be estimated reliably from speech pauses (as, e.g., in tandeming operations). Objective tests confirm that the use of environmentally adaptive measures significantly improves estimation accuracy in noisy speech, while preserving the quality in the case of clean input.

    A technological framework supporting knowledge exchange in organizations2004Ingår i: ACM Int. Conf. Proc. Ser., 2004, s. 381-384Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper focuses on presenting a technological framework for supporting knowledge sharing in organizations through computer support. The framework is based on the results from three studies of organizational knowledge in three kinds of settings and focuses on communication between people, awareness information about people's activities and availability, and information management. The third study also included an evaluation of a number of prototypes developed based on the three areas focused on in the framework. The results from the evaluation indicate that the framework is suitable for the purpose of supporting knowledge exchange.

    Presence Design: Mediated Spaces Extending Architecture2010Doktorsavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    This thesis is a contribution to design-led research and addresses a readership in the fields of architecture as well as in media and communications. In juxtaposing the tools of the designer (e.g. drafting, prototyping, visual/textual/spatial forms of montage) with those of architectural theory, this thesis seeks to extend the disciplinary boundaries of architecture by observing its assimilation of other media practices. Its primary contribution is to architectural design and theory, and its aims are twofold:

    Firstly, this thesis applies the concepts of virtual and mediated space to architecture, proposing an extended architectural practice that assimilates the concept of remote presence. Through realized design examples as well as through the history and theory of related concepts, the thesis explores what designing mediated spaces and designing for presence entails for the practicing architect.

    As a fusion of architecture and media technology, video-mediated spaces facilitate collaborative practices across spatial extensions while simultaneously fostering novel and environmentally sustainable modes of communication. The impact of presence design on workplace design is examined. As an extended practice also calls for an extended discourse, a preliminary conceptual toolbox is proposed. Concepts are adapted from related visual practices and tested on design prototypes, which arise from the author’s extensive experience in designing work and learning spaces.

    Secondly, this thesis outlines presence design as a transdisciplinary aesthetic practice and discusses the potential contribution of architects to a currently heterogeneous research field, which spans media space research, cognitive science, (tele)presence research, interaction design, ubiquitous computing, second-order cybernetics, and computer-supported collaborative work. In spite of such diversity, design and artistic practices are insufficiently represented in the field. This thesis argues that presence research and its discourse is characterised by sharp disciplinary boundaries and thereby identifies a conceptual gap: presence research typically fails to integrate aesthetic concepts that can be drawn from architecture and related visual practices. It is an important purpose of this thesis to synthesize such concepts into a coherent discourse.

    Finally, the thesis argues that remote presence through the proposed synthesis of architectural and technical design creates a significantly expanded potential for knowledge sharing across time and space, with potential to expand the practice and theory of architecture itself. The author’s design-led research shows that mediated spaces can provide sufficient audiovisual information about the remote space(s) and other person(s), allowing the subtleties of nonverbal communication to inform the interaction. Further, in designing for presence, certain spatial features have an effect on the user’s ability to experience a mediated spatial extension, which in turn, facilitates mediated presence. These spatial features play an important role in the process through which trust is negotiated, and hence has an impact on knowledge sharing. Mediated presence cannot be ensured by design, but by acknowledging the role of spatial design in mediated spaces, the presence designer can monitor and, in effect, seek to reduce the ‘friction’ that otherwise may inhibit the experience of mediated presence. The notion of ‘friction’ is borrowed from a context of knowledge sharing in collaborative work practices. My expanded use of the term ‘design friction’ is used to identify spatial design features which, unaddressed, may be said to impose friction and thus inhibit and impact negatively on the experience of presence. A conceptual tool-box for presence design is proposed, consisting of the following design concepts: mediated gaze, spatial montage, active spectatorship, mutual gaze, shared mediated space, offscreen space, lateral and peripheral awareness, framing and transparency. With their origins in related visual practices these emerge from the evolution of the concept of presence across a range of visual cultures, illuminating the centrality of presence design in design practice, be it in the construction of virtual pictorial space in Renaissance art or the generative design experiments of prototypical presence designers, such as Cedric Price, Gordon Pask and numerous researchers at MIT Media Lab, Stanford Institute and Xerox PARC.

    Hållbarhetsarbete och kommunikation: En studie av AB Bollnäs Bostäders verksamhet2017Självständigt arbete på avancerad nivå (yrkesexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Syftet med studien har varit att synliggöra AB Bollnäs Bostäders hållbarhetsarbete utifrån 18 framtagna hållbarhetskategorier fördelade på de ekologiska, sociala och ekonomiska hållbarhetsaspekterna. De ekologiska och sociala hållbarhetskategorierna är tagna från ISO26000, en standard som beskriver företags samhällsansvar, och de ekonomiska hållbarhetskategorierna är framtagna med utgångspunkt i tidigare forskning och dokument gällande hållbarhetsaspekter i fastighetsbranschen. Vidare har studien som syfte att synliggöra kommunikationen kring hållbarhetsarbetet genom att analysera vad som kommuniceras och vad resultatet blir av den kommunikationen. Det har gjorts genom att göra en didaktisk analys utifrån de didaktiska frågorna

    för vem, varför, vad och hur. Slutligen har studien som syfte att visa på vad det finns för visioner internt och externt kring AB Bollnäs Bostäders framtida hållbarhetsarbete, med grund i de 18 hållbarhetskategorierna. För att samla in relevant empiri har personliga intervjuer, enkäter och dokumentstudier genomförts.

    Resultatet visar på att AB Bollnäs Bostäder arbetar aktivt mot en hållbar utveckling utifrån alla tre hållbarhetsaspekter - ekologisk, social och ekonomisk. Utav 18 hållbarhetskategorier bedömdes arbetet med 14 av dem vara tillfredsställande. Med välinvesterade resurser skulle bolaget kunna utveckla sitt hållbarhetsarbete och uppfylla alla 18 hållbarhetskategorier. Kommunikationen kring hållbarhetsarbetet uppvisar övervägande ekonomiskt innehåll både internt och externt, men med olika syften för de olika målgrupperna boservice, ekonomi och administration, kundcenter, parkenheten, tekink, VD, boende, entreprenörer, kommunfullmäktige samt styrelsen. Utfallet däremot visar på att det är de ekonomiska, sociala och ekologiska hållbarhetskategorierna, i nämnd ordning, som uppfattas av de olika målgrupperna. Slutligen framgick det av resultatet att alla tre hållbarhetsaspekter ansågs vara viktiga för AB Bollnäs Bostäder i framtiden, men de ekonomiska hållbarhetskategorierna bedömdes ha högre prioritet.

    Abstract [en]

    Building and modifying knowledge-based systems requires testing of the knowledge for quality assurance, such as verification and validation. This is especially important when reverse engineering is applied to a system that needs to be remodeled or renewed. However, the modification of a knowledge-based system is a difficult process. Commonly, the documentation is poor, and the original domain expertise is lacking. Therefore, testing must be applied on existing knowledge to be able to verify the changed knowledge. To this objective we apply an automated test generation system to verify the operation of the modified system.

    Abstract [en]

    Leaders make decisions in different and sometimes difficult situations. These decisions are often converted into valuableknowledge needed by other people in decision positions. For example, students becoming leaders need knowledge about leadershipto make good judgments. When the situation is sensitive, perhaps concerning personal changes or an unfamiliar business strategy,leaders need opinions and not just those from people involved in the company. An artificial system allows us to replicatea system of opinions and observations from outside advisors, which is why we base our research on this kind of system. Inthis paper we present a knowledge representation for a knowledge-based leadership system used in the experimental system weare developing.

    Language technology for eGovernment - business cases2014Ingår i: New Perspectives in Information Systems and Technologies, Volume 1, Springer, 2014, nr VOLUME 1, s. 83-95Konferensbidrag (Refereegranskat)
    Abstract [en]

    Language technologies and tools, such as text mining, information extraction, and question and answering systems, have been developed during many years. These technologies are becoming mature and should be ready for deployment in private and public organizations. However, little focus has been paid to how these technologies can be applied to tackle real-world problems within organizations. In this paper, we present a set of business cases where language technologies can have a significant impact on public organizations, including their business processes and services. We describe how each business case can influence the service quality, as seen from a consumer perspective, and the business processes efficiency, as seen from a public organizational perspective. The business cases are based on, and exemplified with, cases from large Swedish public organizations.

    The importance of communicating vision, goal and strategy in a consultancy firm: A case study2013Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    This study explores the case of company, Kompany, and the event, where one of Kompany’s commissions with one of their clients ended, due to problems arising in the areas of accounting practices-, organisational communication, organisational culture and the power distribution within the company. Hence, the study aims to create an understanding of why the commission ended and if the factors associated to this event are also inherent in the organisation as a whole.

     

    This study investigates the use of accounting practice as a language to describe communication problems that can arise due to cross-professional barriers between engineers and economists. Furthermore, communication is evaluated through the lens of organisational culture and power distribution as to see how these affect each other, and if there is any distinction between them.

     

    This study concludes that an organisation’s culture and its vision, goal and strategy greatly depends on each other. Having no communicated vision, goal or strategy affects the organisational culture in a negative way, and vice versa, ultimately affecting the way a company conducts its business’ and the overall success of the company. In the case of Kompany, this is their current situation, no formal vision, goal or strategy is formulated, hence not communicated within the organisation. As such, this might be the factor that, in the event, led to the situation where Kompany’s commission with one of their biggest clients, ended. These findings can also be used to gain an insight into similar problems, experiences by other companies in the IT-consultancy sector.

    Human interaction as a model for spoken dialogue system behaviour2010Doktorsavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    This thesis is a step towards the long-term and high-reaching objec-tive of building dialogue systems whose behaviour is similar to a human dialogue partner. The aim is not to build a machine with the same conversational skills as a human being, but rather to build a machine that is human enough to encourage users to interact with it accordingly. The behaviours in focus are cue phrases, hesitations and turn-taking cues. These behaviours serve several important communicative functions such as providing feedback and managing turn-taking. Thus, if dialogue systems could use interactional cues similar to those of humans, these systems could be more intuitive to talk to. A major part of this work has been to collect, identify and analyze the target behaviours in human-human interaction in order to gain a better understanding of these phenomena. Another part has been to reproduce these behaviours in a dialogue system context and explore listeners’ perceptions of these phenomena in empirical experiments.

    The thesis is divided into two parts. The first part serves as an overall background. The issues and motivations of humanlike dialogue systems are discussed. This part also includes an overview of research on human language production and spoken language generation in dialogue systems.

    The next part presents the data collections, data analyses and empirical experiments that this thesis is concerned with. The first study presented is a listening test that explores human behaviour as a model for dialogue systems. The results show that a version based on human behaviour is rated as more humanlike, polite and intelligent than a constrained version with less variability. Next, the DEAL dia-logue system is introduced. DEAL is used as a platform for the re-search presented in this thesis. The domain of the system is a trade domain and the target audience are second language learners of Swedish who want to practice conversation. Furthermore, a data collection of human-human dialogues in the DEAL domain is presented. Analyses of cue phrases in these data are provided as well as an experimental study of turn-taking cues. The results from the turn-taking experiment indicate that turn-taking cues realized with a di-phone synthesis affect the expectations of a turn change similar to the corresponding human version.

    Finally, an experimental study that explores the use of talkspurtinitial cue phrases in an incremental version of DEAL is presented. The results show that the incremental version had shorter response times and was rated as more efficient, more polite and better at indicating when to speak than a non-incremental implementation of the same system.

    The Phrase-Final Accent in Kammu: Effects of Tone, Focus and Engagement2009Ingår i: INTERSPEECH 2009: 10TH ANNUAL CONFERENCE OF THE INTERNATIONAL SPEECH COMMUNICATION ASSOCIATION 2009, BAIXAS: ISCA-INST SPEECH COMMUNICATION ASSOC , 2009, s. 2439-2442Konferensbidrag (Refereegranskat)
    Abstract [en]

    The phrase-final accent can typically contain a multitude of simultaneous prosodic signals. In this study, aimed at separating the effects of lexical tone from phrase-final intonation, phrase-final accents of two dialects of Kammu were analyzed. Kammu, a Mon-Khmer language spoken primarily in northern Laos, has dialects with lexical tones and dialects with no lexical tones. Both dialects seem to engage the phrase-final accent to simultaneously convey focus, phrase finality, utterance finality, and speaker engagement. Both dialects also show clear evidence of truncation phenomena. These results have implications for our understanding of the interaction between tone, intonation and phrase-finality.

    Modelling from Knowledge versus Modelling from Rules using UML2005Ingår i: Knowledge-Based Intelligent Information and Engineering Systems: KES2005 / [ed] Rajiv Khosla, Robert J. Howlett, Lakhmi C. Jain, Berlin Heidelberg: Springer Berlin/Heidelberg, 2005, s. 393-402Konferensbidrag (Refereegranskat)
    Abstract [en]

    Modelling support for knowledge acquisition is a tool for modelling domain knowledge. However, during the implementation of the knowledge new knowledge is created. Event though this knowledge is found in the knowledge base, the model usually is not updated with the new knowledge and do, therefore, not contain all the knowledge in the system. This paper describes how different graphical models support the complex knowledge acquisition process of handling domain knowledge and how these models can be extended by modelling knowledge from rules in a knowledge base including probability. Thus, the models are designed from domain knowledge to create production rules but the models are also extended with new generated knowledge, i.e., generated rules. The paper also describes how different models can support the domain expert to grasp this new generated knowledge and to understand the uncertainty calculated from rules during consultation. To this objective, graphic representation and visualisation is used as modelling support through the use of diagrams of Unified Modelling Language (UML), which is used for modelling production rules. Presenting rules in a static model can make the contents more comprehensible and in a dynamic model can make the uncertainty more evident.
