    The eight continent: design for an intentional surprise2013In: Proceedings: 2013 International Conference on Cyberworlds / [ed] Xiaoyang Mao, Lichan Hong, Los Alamitos: IEEE Computer Society, 2013, p. 232-239Conference paper (Refereed)
    Abstract [en]

    In this paper I will present and discuss the design thinking, methods, processes and some examples of work, that demonstrates how I together with different co-creators set up a work practice, using digital 3d objects and images. That in different ways and formats helps us to explore how a database, a set of rules can be used in a dialogue with artistic work practice and how such a process can be used to create images and animation in a variety of design and art projects. The main example is a project called Conversation China that still is in its making, here we work with rather complex processes, involving several digital analogue techniques as the basis for creating the images for a 150 pieces porcelain dinner set. My interest in this work is how the intention of the artist or designer is transferred and later embedded in the procedural or algorithmic process and how this intent is organized and set up to secure an desired outcome, mixing the possibilities of the digital media object with manual editing and artistic craftsmanship. With the idea of design fiction, we continue to ask and explore how intent can be critical to the design process as well as the final result, that is rendered between the procedural techniques and the artistic intention. What this paper tries to put forward is how we designed and set up environments for working with non linear and procedural media, their different expressions and forms by using explorable prototypes and design thinking?

    The people´s smart sculpture PS22016In: ISEA 2016: Journey to Abadyl / [ed] Martin Koplin, 2016Conference paper (Other (popular science, discussion, etc.))
    Abstract [en]

    The People’s Smart Sculpture (PS2) panel discusses future oriented approaches in smart media-art, developed, designed and exploited for artistic and public participation in the change and re-design of our living environment. The actual debate about a smart future is not taking into account any idea of media art as an instrument for to realize the social sculpture, mentioned by Beuys[1] or as social sculpture itself.

    The People’s Smart Sculpture is the only large scale Creative Europe media-art project (2014-2018) in this context. It fosters participative-art and collaborative media-art-processes. The artistic results and the open approaches of the project will be discussed by 5 panelists from 5 countries. The project itself is constituted by 12 project-partners in 8 European countries with more than 350 artists and creatives from 29 countries worlwide. The approach works on two levels: the implementation of cultural participation-projects by media-artists and the ongoing optimization of the art and participation aspects. PS2 integrates diverse groups of people to participate in the non-institutional set up of structures for the people´s re-design of their urban, societal and living environment. Artists, citizens, creatives with a new user's perception and new skills are able to „medialize“ the Cultural R>evolution of art, culture, society and science: into spaces of a new public.

    Wanderlost2014In: Cyberworlds (CW), 2014 International Conference, 2014Conference paper (Refereed)
    Abstract [en]

    In this paper I will discuss a art and design project called wander lost, were we through co-creation try to populate a virtual world with people, objects and architecture. In this project we have developed a method for gathering input and inspiration for early stages in the design process designing virtual worlds. I will through some example of work show how worlds, real and virtual are as much made as found, and how they can be used to challenged each other into new forms of experiences and expressions, of both physical and virtual spaces. Where the virtual space transformed into maps & instructions can challenge the physical with qualities that is very hard to achieve in the physical world itself, and in that conflict new insights and expressions can revealed. Today Hybrid creations have become a method for working with cultural production not only with different elements of form, but as blending identities of the creators as well, wander lost support that process. We show how we from the virtual settings of the city of Traora we have extracted a series of walks as instructions and invited different co-creators to explore these algorithmical walks in their everyday surrounding in order to be surprised by rediscovery, using a digital camera/smart phone to capture and later communicate their findings. Allowing the unfamiliar to co-exist with the comfortably familiar. To create a process where digital worlds challenge and inspire digital expressions, tools and models with physical play and exploration. Supporting our long-term aim with research in new media is to set up design methods that can be used in a creative and collaborative process. We show how these findings played a crucial role designing the virtual city Traora. The Traora Flaneur kit turns everyday walks into discoveries of both urban contexts as well as ideas for possible virtual worlds.

    Ideal spaces: digital-cultural ecology and the medium-sized city2016In: Digital-cultural ecology and the medium-sized city / [ed] S. Sparke & G. Cairns, 2016, p. 5-Conference paper (Refereed)
    Abstract [en]

    In our working group Ideal Spaces we are concerned with mediated worlds: especially the one of ideal worlds reconstructed, mainly concentrating on a classical topic of a “mediated” city through history, namely that of a utopian ideal city. How these utopian places have to be conceived as being ‘ideal’ ones. How this has been mediated, in terms of their modes of presentation, but also in those of the ideas underlying them as regards the different audiences that were thought to be addressed by them?

    These historical conceptions of what an ‘ideal world’ should, or could be is a classical topic of our cultural sphere, and focuses upon one perspective of relevance, that of an ideal city. The latest since the onset of what has been called ‘modernity’, now providing the actual background of the actually built cities we all live in, as our environment of relevance.

    Such conceptions of ‘ideal’ relevant worlds can be compared, as a background folio, with the approaches towards an ‘ideal’ environment as they become evident in the concept of The City of Abadyl. That in itself is a proposed city, a fantasy, a set of codes and models, a library of artefacts and prototypes, and foremost, it is its co-creators. Since its inception in 1999 it has grown into a large database of materials interlinked through the shape of a city, regardless of their respective incompatibilities. Support and create a geatlt for inquary

    Our approach is to create an environment which facilitates artistic work practice in complex production environments such as those of digital media, supporting invited artists, researchers, companies, and students. We establish a ready-made, fictitious gravity that others can easily transfer their knowledge into. So How do we go about exploring this complex digital space? We could let people walk the streets of Abadyl in for example a game engine, but we have so far chosen to go in another direction. We have used the framework of Abadyl to stage different events in the form of written scenarios that provide detailed and specific background material. Our scenarios try to bring aspects of field study and fantasy together, to slowly create a discrete dynamic tension or displacement between persons, objects, time, places, and events that are not usually, if ever, associated into new and surprising conjunctions. Through this work we have developed several methods of worldmaking. The aspect of imagery is of particular importance here since comparisons can be made between traditional conceptions of pre-planned ideal worlds – e.g., the ideal of a functionalist city, of a typically ‘modern’ one, etc. – and imageries that evolve de novo and unplanned, as it is tried in the case of Abadyl.

    Moreover, such comparisons inform about a further aspect of imagery and hence, of being mediated. We have to take the notion of the ideal in both its connotations as a mental or inner image on the one hand (from the Greek eidos, or idea); and on the other, as a perfect state to be achieved and longed for (the ideal in its common terms of understanding). If we do so, then it becomes evident that even seemingly ‘new’ and ‘spontaneous’ outcomes like those in Abadyl are informed by mental or ‘inner’ images deeply rooted in what is called a cultural memory, that is, rest on a culture-specific substratum. And it is very interesting to see how these both layers of imagery, the “new” and the “old” one, are influencing each other in mutual terms. Which is a very important topic of mediated cities today since the assumption is that what is happening in Abadyl is also happening here.

    Gestalt2015Conference paper (Refereed)
    Abstract [en]

    Many disciplines have the culture and nurturing to explore, create, and tell stories about worlds. Therefore, our contribution is about the re-discovery of an idea that has been crucial in occidental thinking and which became underestimated: the notion of gestalt. To conceive real-world (and other) phenomena in terms of gestalt helps to gain a holistic understanding of them, and the aim of our paper therefore is to promote a method to rediscover the world in a less analytical fashion than it has been done in the last 400 years, after an analytical-based perception of reality gained ground with the scientific method developed in the 17th century and later. At the same time, a gestalt-approach helps to reframe (and better understand) recent technological developments as outcomes of an analytical way of thinking. Because analysis and the shaping of processes and entities according to functionalities is not the only or most suitable way to generate understanding, despite we got used to such a general state of mind.

    To conceive the world primarily in analytical terms or as a set of functions became culturally accepted. A gestalt-approach can be a promising complement to the prevalent analytical approaches, and the general benefit of such an approach lies in the use of comparative methods to create knowledge or design processes. Also borrowing ideas from Design Theory where Gestalt is analogous to a design process, we can view it as a process of knowledge acquisition and learning from the previously unknown.

    Gestalt perception as well as -conception helps to develop another kind of epistemology than the prevalent analytical/functional one, as for instance cybernetics, system theories and bioengineering already demonstrated. It transcends the border between real and virtual towards envisioning a complete reality, and out of that proves to be a method of working with unknown phenomena.

    Analysis of Facebook content demand patterns2014In: SaCoNet 2014 / [ed] Said Hoceini, Guang-Jie Ren och Eva Marín-Tordera, IEEE Communications Society, 2014Conference paper (Refereed)
    Abstract [en]

    Data volumes in communication networks increase rapidly. Further, usage of social network applications is very wide spread among users, and among these applications, Facebook is the most popular. In this paper, we analyse user demands patterns and content popularity of Facebook generated traffic. The data comes from residential users in two metropolitan access networks in Sweden, and we analyse more than 17 million images downloaded by almost 16,000 Facebook users. We show that the distributions of image popularity and user activity may be described by Zipf distributions which is favourable for many types of caching. We also show that Facebook activity is more evenly spread over the day, compared to more defined peak hours of general Internet usage. Looking at content life time, we show that profile pictures have a relatively constant popularity while for other images there is an initial, short peak of demand, followed by a longer period of significantly lower and quite stable demand. These findings are useful for designing network andQoE optimisation solutions, such as predictive pre-fetching, proxy caching and delay tolerant networking.

    Abstract [sv]

    Akademisk skrivande för studenter på datasystemutvecklingsprogrammet (ett kandidatprogram i datalogi) har alltid varit en komplex uppgift. Studenter skriver många rader av programkod i nästan varje kurs. Kodningen dokumenteras i projektrapporter där tyngdpunkten ligger på tekniska detaljerna. En viktig fråga är hur studenter kan lära sig att skriva akademiska uppsatser? Examensarbete på datasystemutvecklingsprogrammet körs på halvfart. Som ett självständigt arbete krävs det mycket disciplin av studenter. Ett av lärandemålen säger att studenter ”ska kunna självständigt identifiera, formulera och lösa problem samt att genomföra uppgifter inom givna tidsramar”. Vad behövs för att studenter ska bli färdiga i tid?

    Med inspiration från Sjuksköterske- och Ekonomprogrammet vid Högskolan Kristianstad har vi byggt en modell som gör att studenter inom datasystemutvecklingsprogrammet klarar av att skriva akademiska uppsatser. Lärare från Sjuksköterskeprogrammet inspirerade oss med sin modell av examensarbete, där mittseminarium inte är ett obligatoriskt moment. Lärare från Ekonomprogrammet inspirerade oss med akademisk slinga, som har för syfte att integrera generella kompetenser och färdigheter i ämneskurser i grundutbildningar. I sin grundform ska akademisk slinga även utveckla studenternas kommunikativa förmågor (skriva, tala) och förmågan att lösa problem och arbeta i grupp.

    Även CDIO modellen som datasystemutvecklingsprogrammet är byggd på, har spelat en stor roll då studenter har lärt sig jobba både självständigt och i grupp. Seminarium som undervisningsform används genomgående i utbildningen. Det vetenskapliga förhållningssättet medvetandegörs och konkretiseras i olika projekt och laborationer. Där bland annat tränar studenter att hitta en vetenskaplig vinkling på de tekniska lösningarna.

    Kursen Examensarbete Datalogi består av flera moment: idé - grupphandledning-projektplan - handledning -mittseminarium -handledning -slutpresentation. Alla moment har sina deadlines och riktlinjer.

    Resultatet visar att ”vältränade” studenter klarade av denna uppgift. VT2016 fick 15 av 16 kandidatstudenter godkänd projektplan och 13 av de 15 studenter presenterade sittexamensarbete i tid.

    SOCIAL ART IN EUROPEAN SPACES - AN APPROACH TO PARTICIPATION METHODOLOGIES WITHIN PS22016In: INTED 2016: 10TH INTERNATIONAL TECHNOLOGY, EDUCATION AND DEVELOPMENT CONFERENCE / [ed] Chova, LG Martinez, AL Torres, IC, 2016, p. 1690-1699Conference paper (Refereed)
    Abstract [en]

    The People's Smart Sculpture PS2 - Social Art in European Spaces is a creative research and innovation project about the cultural evolution of the European city of the future. It addresses the growing complexity of life in today's city spaces and imminent challenges to the development of the urban environment. The People's Smart Sculpture PS2 explores the possibilities of participation that will become a smart culture technique as a result of the ongoing digitalization of society. 12 partners including universities, educational institutions, museums, galleries, theatres and research institutes in 8 European countries will organize 11 connected open labs integrating new art, design thinking, science, smart technologies and user culture for the participatory re-design of urbanity. The project has a budget of 2 million Euros and is funded by the European Commission within the Creative Europe programme for 3.5 years. 11 creative experiments in participatory art and design for the city of the future: The 12 project partners implement 11 experimental sub-projects and a European study about new forms of participation. While some PS2 sub-projects shed light on the ways we perceive our city space, or create speculative city environments, others will analyse problems, identify challenges and explore interdisciplinary solutions with citizens. The variety of approaches will reflect the diversity of people, skills, urban art, social processes and urban development. Renowned artists and designers from 29 countries will participate in the sub-projects. PS2 will explore and document new strategies for involving digital media and ICT in the development of user-centred culture. Development of new forms of participation for Smart Cities: Scientists from media-labs, computer science, cultural science, art history, sociology, architecture, design and urban planning will engage with the creative processes. Digital technologies will not only play an important role in the PS2 project art activities themselves, but directly support the innovation process by offering new opportunities for empowerment and societal integration of people of all social groups. The project will connect people and foster the exchange of ideas about and for smart cities. It is the base for cutting-edge communication between science and art, creatives, artists, media designers and citizens, and between the people and their governments. At the same time it will motivate the broad dissemination of new skills, design expertise and social knowledge relevant to urban re-design. Citizen participation in urban development and re-design has a long cultural tradition in Europe. But the rising complexity out of social issues, critical and creative ideas, green development, and at the same time a high level of demands towards a post-modernistic cultural evolution evoke the need of improved cooperation between all stakeholders in town: governmental entities, creative, and social cultural activists, experts and citizens. The participation processes needed for future activities in the field of urban-social sustainability requires an enhanced approach to citizen participation and user-friendly creative articulation. It is required to access the full potential of the new capabilities of communication, networking, social media, creativity, microcomputers, and new e-skills through the design of new participation methodologies. Art and media art prototype the next step concepts and methodologies for participation. This paper describes concepts and approaches of participation and reflects on participative art within examples of 6 PS2 sub-projects.

    zCap: a zero configuration adaptive paging and mobility management mechanism2013In: International Journal of Network Management, ISSN 1055-7148, E-ISSN 1099-1190, Vol. 23, no 4, p. 235-258Article in journal (Refereed)
    Abstract [en]

    Today, cellular networks rely on fixed collections of cells (tracking areas) for user equipment localisation. Locating users within these areas involves broadcast search (paging), which consumes radio bandwidth but reduces the user equipment signalling required for mobility management. Tracking areas are today manually configured, hard to adapt to local mobility and influence the load on several key resources in the network. We propose a decentralised and self-adaptive approach to mobility management based on a probabilistic model of local mobility. By estimating the parameters of this model from observations of user mobility collected online, we obtain a dynamic model from which we construct local neighbourhoods of cells where we are most likely to locate user equipment. We propose to replace the static tracking areas of current systems with neighbourhoods local to each cell. The model is also used to derive a multi-phase paging scheme, where the division of neighbourhood cells into consecutive phases balances response times and paging cost. The complete mechanism requires no manual tracking area configuration and performs localisation efficiently in terms of signalling and response times. Detailed simulations show that significant potential gains in localisation efficiency are possible while eliminating manual configuration of mobility management parameters. Variants of the proposal can be implemented within current (LTE) standards.

    Study of YouTube demand patterns in mixed public and campus WiFi network2014In: TRAC 2014 / [ed] Pedro Casas och Brian Trammell, IEEE Communications Society, 2014Conference paper (Refereed)
    Abstract [en]

    In this paper we study traffic patterns in a large municipal WiFi network and in particular those of the most bandwidth hungry application, viz. YouTube, for which we provide a detailed analysis of demand in different geographical areas and over time. We consider the possibilities to reduce network traffic and increase Quality of Experience (QoE) by serving repeated requests for YouTube videos from caches placed either at the network head end, at the wireless access points, or in the user devices. Our data confirms that a significant part of the YouTube traffic can be served by such devices and that there exists a potential to optimize caching performance by exploiting the content demand locality. We also discover a previously unknown pattern of periodicity in content demand and present a simple example of how to exploit this in cache design.

    Concurrency and locality of content demand2013In: 2013 International Conference on Smart Communications in Network Technologies (SaCoNeT 2013): proceedings of a meeting held 17-19 June 2013, Paris, France / [ed] Jorge López de Vergara och Brice Agustin, 2013Conference paper (Refereed)
    Abstract [en]

    Distribution of media data over the Internet is increasing in popularity and volume. This poses challenges not only for network operators but also for service providers when it comes to serving the demand in a cost-efficient way. In this paper, we approach this problem by investigating the potential of co-operative approaches where locality in space (users in the same network) and locality in time (concurrent downloads) are exploited such that as many requests as possible may behandled inside the access and metro networks. This approach may contribute not only to reducing transport costs (less traffic in core networks and at peering points) by but also improve the end user experience (by reduced round trip times and exclusion of some possible bottlenecks). To this end we develop a method to measure the possible gains from, firstly, optimal handling of concurrent downloads and, secondly, optimal utilization localavailability. We apply the method to BitTorrent data from two metropolitan access networks and find that the bandwidth savings amount to between 10% and 20% when optimizing concurrent downloads and between 56% and 66% when exploiting local availability with a simulated network cache.

    Computer-based training program for health- and acre professionals involved in breastfeeding support, an intervention project that involve decision makers, professionals and care users2016Conference paper (Refereed)
    Abstract [en]

    There is an urgent need to facilitate the development of more effective breastfeeding support strategies. The desired research will focus on knowledge-based service innovation that include intervention in form of computer-based training program aimed for training of health and care professionals involved in breastfeeding support. The intervention in the proposed study will contribute to more effective adoption of new knowledge in healthcare organisations. Further, the proposed project will be organised as an interdisciplinary and crosswise sectorial collaboration and will be customized at a national and international level, by involving decision-makers, researchers, health care professionals and care users. Ambition with this project is to contribute to increased breastfeeding frequency by increasing competence in professional support in related healthcare services and midwife education program. There is also an urgent need for evidence based technical solutions as a professional support for the professionals to more effectively implement new research in practice. This project will contribute health care with high quality and resource use. The overall aim for the project is to implement and evaluate new innovative solutions in order to improve long-term strategies for professional support and quality of care, related to knowledge-based breastfeeding support. The design method for the project is longitudinal randomized controlled intervention trial. The intervention will be computer-based training education program developed in collaboration with decision-makers, professionals and researchers. Data will be gained before and after intervention by using: Breastfeeding attitudes among counselling health professionals (An instrument based on WHO standards was developed to measure breastfeeding attitudes), Mother-to-infant Relation and Feelings (MIRF) scale and Mother-Perceived-Professional-Professional support (MoPPS) scale. For successful intervention, it is important that decision-makers are involved in the research process, so that suggested changes can be possible if they actively participate and encourage the project as well as the adoption of research results in practice. Involvement of stakeholders in the research demand facilitation of the research process. This can enable cooperation by using project management techniques as co-counselling and clinical reflection. The outcome of the project will be multiple may be placed in a regional, national, international or global context. Firstly, the project will contribute to development of knowledge-based professionals’ competence with focus on to support breastfeeding from first breastfeeding time, to minimise usage of infant formula during first week of life, longer exclusive- and predominant breastfeeding and stronger connection between mother and child. This topic will fit with theme Nutrition and Lactation.

    B.E.A.C.O.N. - Beacon Emits Audio from Color, Or Not2013Conference paper (Refereed)
    Abstract [en]

    People who suffer from dementia are often isolated due to lack of ways of communication. In many cases verbal communication can be difficult to perform at all. We created Beacon with the goal to let people with dementia interact with a very simple and intuitive control interface to give them a means of non-verbal communication, and let them take control over the soundscapes that Beacon is capable of producing. In this paper we describe our concept Beacon, its physical form and how the design makes it possible for a person with dementia to control the software by moving around items of different colors and sizes on its surface to create synthesized and sampled sounds. We hope that Beacon will produce positive results among people with dementia, and that the interaction will be rewarding.

    Behaviour of Common TCP Variants over LTE2016In: IEEE Globecom 2016: Mobile and Wireless Networks Symposium, 2016Conference paper (Refereed)
    Abstract [en]

    This paper presents our work regarding the comparison of the behaviour of some of the major TCP variants in a LTE network. Using the LENA LTE simulator and the DCE framework, the behaviour of the Linux implementations of seven TCP variants are compared. The evolution of the throughput, congestion window and queuing delay are studied for four scenarios with different network loads and flow types. Our measurements show that, in the situations we consider, most variants are able to quickly reach full link utilisation. However, to reach the same throughput, they create different amounts of queuing delay. On the one hand, loss based algorithms tend to totally fill the queue, creating huge queuing delays and inducing packet losses. On the other hand, delay based variants manage to limit the queue size and decrease the amount of packet dropped by the eNodeB but struggle to reach the maximum throughput in some circumstances.

    Digital teknik och socialt arbete: att motivera socialt utsatta ungdomar med stöd avmotivationsappar och hälsoarmband2017Report (Other academic)
    Abstract [sv]

    Digital teknik och socialt arbete är en pilotstudie som syftat till att undersöka effekter av att använda aktivitetsarmband med tillhörande motivationsapp för att stärka ungdomars motivation till fysisk aktivitet och goda sömnvanor. Projektet har präglats av ett explorativt angreppsätt i det att vi undersökt hur introduktion av ny digital teknik mottas av olika målgrupper inom socialtjänsten.

    Forskning har visat sig att det finns en tydlig koppling mellan ökad fysisk aktivitet och minskad psykisk ohälsa. Sömnen är ytterligare faktor som spelar en betydande roll för barn och ungas hälsa. Vi har denna kunskap om fysiska aktivitet och sömn i samhället idag samtidigt som barn och ungas psykiska och fysiska hälsosituation utgör ett uppmärksammat folkhälsoproblem. Att barn rör på sig för lite syns hos alla grupper av barn och unga oavhängigt faktorer som familjeförhållanden, arbetsmarknadsstatus och föräldrars samhällsekonomiska status. Enligt Socialstyrelsen (2013) är det av extra vikt att barn och unga uppnår bästa möjliga hälsa eftersom det visat sig att nedsatt hälsotillstånd i unga år kan få betydelse för resten av individens liv. Insatser för att preventivt främja våra barns och ungas hälsa är därför en önskvärd och god samhällsinvestering både för den enskilda individen och för allas vår gemensamma hållbara framtid. Denna rapport beskriver resultatet av ett forsknings-och utvecklingsprojekt där vi undersökt hur appar och aktivitetsarmband skulle kunna användas för att motivera barn och unga till ökad fysisk aktivitet samt bättre sömnvanor. 

    Våra undersökningar av tidigare forskning inom problemområdet har visat på att det finns en tydlig koppling mellan ökad fysisk aktivitet och minskad psykisk ohälsa, såsom t.ex. att fysisk aktivitet kan minska depression och ångest. Fysisk aktivitet har samma effekt som psykologisk behandling och medicinering, men ger betydligt färre biverkningar än medicinering. Det finns också framgångsrika försök med viktminskningsgrupper som arbetat med stöd av digitala lösningar. Tekniken i sig kan bidra med att sätta mål, motivera, och följa upp resultat. Sociala funktioner för att kunna följa andras framsteg har visat sig öka motivation gällande att vara mer fysiskt aktiv. Angreppsätt där man låter användare mäta och följa sitt eget beteende ger den största positiva effekten för att åstadkomma hälsofrämjande beteendeförändringar. 

    Om fysisk aktivitet är bra för hälsa är sömn om möjligt ännu viktigare. Forskning inom sömn visar att det en tydlig koppling mellan sömn och vardagligt välbefinnande. Det har konstaterats att olika typer av sömn har olika funktioner. REM-sömnen har t.ex. påvisat koppling till bättre mönsterigenkänning medan djupsömnen har en påverkan på minnet. Forskning visar också att sömnlöshet påverkar immunförsvaret negativt vilket i sin tur kan bidra till sömnstörningar och övervikt hos ungdomar.

    Vad gäller teknik så visar forskning att professionell kompetens inom hälsa och medicin inte alltid används vid framtagning av teknik, vilket utgör ett återkommande problem. Det är inte enbart är tekniken som måste fungera för att insatsen ska kunna lyckas, attityden till e-hälsa bland befolkningen generellt sett kan också ha en avgörande betydelse. Om den generella bilden av tekniken bland befolkningen är negativ så är det svårt att införa och lyckas med teknikstöd. Teknikutvecklingen är snabb, och vi står inför en dramatisk ökning av olika informations- och telekommunikationsteknologier vars syfte är att förbättra och utveckla egenvård och omsorg. Frågor om integritet hamnar ofta i skymundan. Flertalet av de identifierade relevanta publikationerna fokuserade mer på tekniken än det hälsobefrämjande stödet.

    Vår bibliografiska undersökning visar att det finns förhållandevis lite av samband mellan begrepp som är relaterade till hälsoappar och egenvård kontra motivationsarbete och socialt arbete. De starkaste sambanden av intresse för oss hittade vi i ett gränsland mellan medicin och datavetenskap. Sammanfattningsvis kan vi säga att flertalet av de här identifierade akademiska publikationerna diskuterar de tekniska lösningarna i sig, eller presenterar användarvalidering av olika lösningar; snarare än socialt arbete, eget motivations- och förändringsarbete av dåliga vanor och livsmönster - som är vårt intresseområde i denna studie.

    För att bättre förstå och bidra till utmaningarna så har ett samarbete initierats mellan Helsingborgs stads Forsknings- och utvecklingsenhet för social hållbarhet (FoU Helsingborg), Preventivt arbete tillsammans (PART) från Helsingborgs stad och forskare från både Lunds Internet institut (LUii), Lunds Universitet samt Digital design, Sektionen för hälsa och samhälle på Kristianstad Högskola (HKR). Ett internt utvecklingsprojekt har genomförts av PART med stöd av FoU i Helsingborgs stad. I samband med utvecklingsprojektet har ett gränsöverskridande samarbete initierats där aktionsforskning ramat in utvecklingsprojektets empiriska studie och möjliggjort en gemensam yta för ett bredare kunskapsskapande. Vårt fokus har varit ett kunskapsbildande vad gäller aktivitetsarmband och motivationsappar för barn och unga som löper risk för ohälsa. Denna rapport presenterar en akademisk kunskapsöversikt, samt resultatet från ett utvecklingsprojekt där vi tillsammans undersökt effekterna av att använda aktivitetsarmband och tillhörande social app. Vi har beforskat vilken påverkan dessa kan ha på ungdomars egen motivation till fysisk aktivitet och goda sömnvanor.

    Syftet med pilotprojektet har varit att kartlägga forskningen på området, undersöka de upplevda effekter av att använda aktivitetsarmband med tillhörande motivationsapp för att stärka deltagares motivation till fysisk aktivitet och förbättrade sömnvanor, samt undersöka hur vi kan förstå de faktorer som verkar vara mest betydande för att uppnå effekter. Det senare har vi gjort genom att fokusera på fyra övergripande områden: Användandet av motivationsapp - Hur länge och med vilken frekvens använder deltagarna armband och motivationsapp? Värdeskapande för ungdomar - Till vilka positiva resultat bidrar armband och motivationsapp? Negativa bieffekter - Kan armband och motivationsapp orsaka negativa bieffekter hos deltagarna? Om så, till vilka områden hänför sig dessa bieffekter? Värdeskapande för personal – Vilken nytta ser personalen av armband och motivationsapp i sitt arbete?

    Ur ett forskningsperspektiv så är studien att betrakta som mindre, varvid dess värde skall beaktas utifrån detta. Mer forskning behövs i området motivationsappar och socialt arbete. Studieresultatet visar på faktorer som har betydelse för frågeställningarna, som också kan identifieras i tidigare forskning. Positiva upplevelser har varit att ungdomarna fått en märkbart ökad medvetenhet om sina egna levnadsmönster vad gäller motion och sömn. Tydligast märktes den nya medvetenhet som växte fram runt egna sömnvanor, även att dessa inte alltid gick att åtgärda på egen hand. Det var också uppenbart att den nya medvetenheten ledde ökad motivation och fysisk aktivitet. Identifierade negativa bieffekter var att stress kunde uppstå när ungdomarna var förhindrade att själva öka sitt stegantal samtidigt som de såg andra ungdomars resultat öka. Det rapporterades problem med att sköta den dagliga laddningen av aktivitetsarmbandet, samt att aktivera sömnmätningen när de skulle lägga sig. Ett stort värde för personalen var att de fick ett instrument som berikade kommunikationen utifrån “objektiv” data genererad av ungdomarnas egna mätningar av motion och sömn. Ett verktyg som utgjorde god hjälp för samtal, som i sig kunde bidra till bättre struktur i ungdomars liv.

    Evaluation of new injection and cavity preparation model in local anesthesia teaching2013In: Journal of Dental Education, ISSN 0022-0337, Vol. 77, no 1, p. 51-57Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to evaluate a recently developed preclinical injection and cavity preparation model in local anesthesia. Thirty-three dental students administered an inferior alveolar nerve block injection in the model, followed by preparation on a tooth. The injection was evaluated by three observers, and the feedback from the model was registered. After completion of the practical session, the opinion of the dental students was explored with a ten-item questionnaire. Thirty dental students (91 percent) performed the injection correctly according to the feedback of the model, and twenty-eight students (85 percent) did so according to the expert opinion. The agreement between feedback from the training model and the expert opinion was high. The students were very satisfied with the opportunity to practice with the training model, as indicated by the high scores on each item of the questionnaire. These results suggest that use of this preclinical training model in anesthesia teaching may have beneficial effects on the administration of local anesthetics by dental students.

    A study-case on a project course: seminars, project, feedback and reflections in the context of a student's active learning2016In: Lärarlärdom 2016: Högskolan Kristianstad / [ed] Claes Dahlqvist & Stefan Larsson, Högskolan Kristianstad: Kristianstad University Press , 2016Conference paper (Other academic)
    Abstract [en]

    The paper presents a case-study at Kristianstad University, with the focus on the Software Engineering project based course, given on the second academic year of the programmes within computer science.

    This paper discusses the course design with regard to two main parts of the course: seminars and project, and how those were organized in order to facilitate student’s active learning.

    The active learning here is focusing on several main factors: course design, course design and its relation to the programme, academic loop (i.e. academic loop is part of a couple of selected courses that develop student’s academical skills), seminars forms, individual feedback and course feedback, as well as documented reflections on project work.

    More in deep, the paper presents examples on the pedagogical findings when it comes to seminars organization and how the changes made in the course helped to an increased student active learning. Such information includes: best practice on course design, best practice on seminars exercises, and project work. The results presented are empirical and are based on observations, as well as on a formal and informal feedback.

    Moreover, the paper addresses also the theme of the importance of feedback in students’ active learning. Here, feedback is discussed in terms of: student-course instructor feedback, course instructor-student feedback, individual vs. group feedback, and peer-review.

    Finally, the paper shows reflections on a two dimensional (2D) survey where the results from 2015 and 2016 are compared and discussed, in order to suggest further improvements for an increased student active learning.

    How to increase the students' degree of involvment and participation in project based courses?2016In: Lärarlärdom: 2015, Växjö: Linnéuniversitetet , 2016, p. 182-211Conference paper (Other (popular science, discussion, etc.))
    Abstract [en]

    The degree of students’ involvement and participation in non-examinatory parts of courses at higher level, such as lectures, is often significantly lower than in the examinatory parts. This can especially be seen in project based courses, where the main examination form is done through the application of the-ory into a practical project, rather than through a written examination. More spe-cific, this paper focuses on two such courses, from the area of software engineer-ing. The courses are given on the second, respectively third year, of the Bachelor Programme in Software Development, at Kristianstad University. These are also part of the academic loop of the programmes. Here, the lectures were replaced by seminars based teaching, with the purpose of raising the students’ degree of ac-tive- involvement and participation into the courses, ensuring a better learning quality, enabling more interaction between the groups of students, and finally fa-cilitating a higher application of the theory into the practical project. Through concrete examples, the paper will showcase the changes that were made in these two courses, with regard to the learning outcomes, the academic loop, and forma-tive examination forms, such as seminars, with the purpose of increasing the qual-ity of teaching and learning. Finally, the immediate positive effects of these changes show we need to look further on how we can find more innovative ways of teaching and learning, especially in the project based courses, in order to in-crease student’s degree of involvement and participation.

    Videomaterial på Designerns Bord – ett gripbart gränssnitt för hantering av videomaterial2001Conference paper (Refereed)
    Abstract [sv]

    Artikeln presenter ett VideoBord med några VideoKort. VideoBordet är ett mötesbord som möjliggör kollaborativ utforskning och bearbetning av videomaterial under designsessioner via ett gripbart gränssnitt för många användare. VideoKorten är papperskort med en stillbild och text som tillsammans representerar viktiga nyckelsekvenser i videomaterialet. Respektive nyckelsekvens kan spelas upp genom att en knapp, som finns monterad på varje VideoKort, trycks in av någon deltagare i design sessionen. VideoKorten kan ligga utspridda på VideoBordet tillsammans med andra fysiska objekt. Därigenom kan mötesdeltagarna blanda "länkade" fysiska representationer av videomaterial med andra fysiska artefakter under brainstormsliknande designsessioner. Därigenom hanteras den utmaning som ligger i att blanda videons lite ogripbara och kortlivade karaktär med fysiska artefakters mer bestående och påtagliga gripbarhet. Implementeringen bygger på passiva RFID-taggar (Radio Frequency Identification) som är permanent monterade på varje enskilt VideoKort. RFID-taggen är dock modifierad så att aktivering enbart sker genom att användarna, via en knapptryckning på respektive kort, explicit ger uttryck för att man önskar få den speciella videosekvensen uppspelad. Preliminära observationer under en design workshop indikerar att den direkta fysiska manipulationen av VideoKorten tillsammans med dess direkta koppling till respektive videosekvens möjliggör den mix mellan fysiska artefakter och digital video som eftersträvades.

    Kvalitetssäkring i högre utbildning2016In: Lärarlärdom 2016: Högskolan Kristianstad / [ed] Claes Dahlqvist & Stefan Larsson, Högskolan Kristianstad: Kristianstad University Press , 2016Conference paper (Other academic)
    Abstract [sv]

    Kvalitetssäkring är ganska viktigt i högre utbildning. Som den sista kursen i ett utbildningsprogram, självständig examensarbete har en tung roll. I de flesta lärosäten, har ett examensarbete en handledare och en examinator. Examinatorn bestämmer vilket betyg ett arbete ska få eller om det ska bli underkänd. Jag har upptäckt två problem i systemet: 1. Bedömning från en individuell examinator är subjektiv och detta har flera konsekvenser, bl.a. icke-förtroendefulla relationer mellan lärare och elev, orättvisa för studenter, och även ojämna kvalité hos universiteten och högskolor; 2. Handledare och examinatorer får en schablon resurstilldelning för varje student och faktiskt blir straffad när en student blir underkänd.

    Medan det första problemet är en allmän fråga, det andra kan vara ett specialfall för oss. Båda problemen undergräver kvalitetssäkringssystemet. Diskussioner här gäller att hitta en lösning till problemen. Bland annat, peer-review, grupp examinering, och arbetsbelastning baserad resursfördelning ska diskuteras.

    Using secret spreading codes to enhance physical layer security in wireless communication2017In: ICC 2017: 3rd International Workshop on Advanced PHY and MAC Technology for Super Dense Wireless Networks, 2017Conference paper (Refereed)
    Abstract [en]

    The broadcast nature of wireless communication make it intrinsically vulnerable to jamming and eavesdropping attacks. Spread-spectrum techniques spread narrowband signals over a wide bandwidth, and provide good resistance to noise and jamming attacks. However, spread-spectrum signals can still be intercepted if their used spreading codes are known. To tackle this issue, this paper proposes a lightweight design on generating secret spreading codes. A secret spreading code has all the desired properties of an ordinary spreading code, plus its unpredictability. Our method on generating secret spreading codes is shown to be resistant to cryptanalysis, and has little requirement on memory and computing resources.

    Localizing multiple objects using radio tomographic imaging technology2016In: IEEE Transactions on Vehicular Technology, ISSN 0018-9545, E-ISSN 1939-9359, Vol. 65, no 5, p. 3641-3656Article in journal (Refereed)
    Abstract [en]

    Low data rate wireless networks can be deployed for physical intrusion detection and localization purposes. The intrusion of a physical object (or human) will disrupt the radio frequency magnetic field, and can be detected by observing the change of radio attenuation. This gives the basis for the radio tomographic imaging technology which has been recently developed for passively monitoring and tracking objects. Due to noise and the lack of knowledge about the number and the sizes of intruding objects, multi-object intrusion detection and localization is a challenging issue. This article proposes an extended VB-GMM (i.e. variational Bayesian Gaussian mixture model) algorithm in treating this problem. The extended VBGMM algorithm applies a Gaussian mixture model to model the changed radio attenuation in a monitored field due to the intrusion of an unknown number of objects, and uses a modified version of the variational Bayesian approach for model estimation. Real world data from both outdoor and indoor experiments (using the radio tomographic imaging technology) have been used to verify the high accuracy and the robustness of the proposed multi-object localization algorithm.

    Long-term effects of a computer-based nutritional training program for inpatient hospital care2017In: Journal of Evaluation In Clinical Practice, ISSN 1356-1294, E-ISSN 1365-2753, Vol. 23, no 4, p. 797-802Article in journal (Refereed)
    Abstract [en]

    Rationale

    A previous short-term study showed that a computer-based training in eating and nutrition increased the probability for hospital inpatients at undernutrition (UN) risk to receive nutritional treatment and care without increasing overtreatment (providing nutritional treatment to those not at UN risk).

    The aim of this study was to investigate if a computer-based training in eating and nutrition influences the precision in nutritional treatment and care in a longer-term perspective.

    Method

    A preintervention and postintervention study was conducted with a cross-sectional design at each time points (baseline and 7 months postintervention). Hospital inpatients > 18 years old at baseline (2013; n = 201) and follow-up (2014; n = 209) were included. A computer-based training was implemented during a period of 3 months with 297 (84%) participating registered nurses and nurse assistants. Undernutrition risk was screened for using the minimal eating observation and nutrition form-version II. Nutritional treatment and care was recorded using a standardized protocol.

    Results

    The share of patients at UN risk that received energy-dense food (+ 25.2%) and dietician consultations (+ 22.3%) increased between baseline and follow-up, while fewer received oral nutritional supplements (-18.9%). "Overtreatment" (providing nutritional treatment to those not at UN risk) did not change between baseline and follow-up.

    Conclusion

    The computer-based training increased the provision of energy-dense food and dietician consultations to patients at UN risk without increasing overtreatment of patients without UN risk.

    Short-term effects of a computer-based nutritional nursing training program for inpatient hospital care2016In: Journal of Evaluation In Clinical Practice, ISSN 1356-1294, E-ISSN 1365-2753, Vol. 22, no 5, p. 799-807Article in journal (Refereed)
    Abstract [en]

    RATIONALE: This study aimed to explore whether a computer-based training in eating and nutrition for hospital nursing staff can influence the precision in nutritional treatment and care.

    METHOD: A pre-intervention and post-intervention study was conducted with a cross-sectional design at each time point. The settings were one intervention (IH) and two control hospitals (CH1 and CH2). Hospital inpatients >18 years old at baseline (2012; n = 409) and follow-up (2014; n = 456) were included. The computer-based training was implemented during a period of 3 months in the IH with 297 (84%) participating registered nurses and nurse assistants. Nutritional risk was screened for using the Minimal Eating Observation and Nutrition Form. Nutritional treatment and care was recorded using a standardized protocol RESULTS: In the IH, there was an increase in the share of patients at UN risk that received energy-dense food (+16.7%) and dietician consultations (+17.3%) between baseline and follow-up, while fewer received feeding assistance (-16.2%). There was an increase in the share of patients at UN risk that received energy-dense food (+19.5%), a decrease in oral nutritional supplements (-30.5%) and food-registrations (-30.6%) in CH1, whereas there were no changes in CH2. 'Overtreatment' (providing nutritional treatment to those not at UN risk) was significantly higher in CH2 (52.7%) than in CH1 (14.3%) and in the IH (25.2%) at follow-up.

    CONCLUSION: The computer-based training seemed to increase the probability for patients at UN risk in the IH to receive nutritional treatment without increasing overtreatment.

    Computer-based training in eating and nutrition facilitates person-centered hospital care: a group concept mapping study2018In: Computers, Informatics, Nursing, ISSN 1538-2931, E-ISSN 1538-9774, Vol. 36, no 4, p. 199-207Article in journal (Refereed)
    Abstract [en]

    Studies have shown that computer-based training in eating and nutrition for hospital nursing staff increased the likelihood that patients at risk of undernutrition would receive nutritional interventions. This article seeks to provide understanding from the perspective of nursing staff of conceptually important areas for computer-based nutritional training, and their relative importance to nutritional care, following completion of the training. Group concept mapping, an integrated qualitative and quantitative methodology, was used to conceptualize important factors relating to the training experiences through four focus groups (n = 43), statement sorting (n = 38), and importance rating (n = 32), followed by multidimensional scaling and cluster analysis. Sorting of 38 statements yielded four clusters. These clusters (number of statements) were as follows: personal competence and development (10), practice close care development (10), patient safety (9), and awareness about the nutrition care process (9). First and second clusters represented "the learning organization," and third and fourth represented "quality improvement." These findings provide a conceptual basis for understanding the importance of training in eating and nutrition, which contributes to a learning organization and quality improvement, and can be linked to and facilitates person-centered nutritional care and patient safety.

    Activity and artifact: the symbiosis of truck drivers’ work and navigational systems2001In: Proceedings of IFIP INTERACT01: human-computer interaction 2001, IFIP Technical Committee No 13 on Human-Computer Interaction , 2001, p. 399-406Conference paper (Refereed)
    Abstract [en]

    This paper outlines design ideas from a project dealing with different interaction concepts for the design of a computer based navigation system for truck drivers. The incentive for thinking about interaction concepts is that programming of navigation systems often occurs while driving, since that is when the support is needed. We have been working with ethnographical studies of truck drivers driving both over short and long distances. There has been quite a lot of work done in the field of cars and navigation, in this paper however the main theme is not navigation in cars as such, but the truck environment as an example of a high-demanding room for work activities. This lead to a design situation where the artifact and the activity has to go together, the artifact has to ‘melt-in’ to the work practice. We discuss how the design of computational power can melt-in to the work-practice without demanding too much of the attention needed for driving the truck safely.
