  Context collapse, or the flattening of multiple audiences into a single context, has been an important notion in research on privacy experiences, self-performance, and changing user practices in social media. Yet, previous research has mainly addressed context collapse in spatial rather than temporal terms. The resulting lack of an understanding of time in social media limits our conception of the social media context. The aim of this article is therefore to go beyond the spatial dimension in the current notion of “context collapse” in social media. We discuss relevant theories, empirical evidence, and technical features that address the importance of a time dimension and suggest a collapse of temporal patterns in social media. By introducing the concept of “time collapse,” we account for how context in social media may muddle the time boundary between past and present, which, in turn, can affect how users manage their identity and performance on social media. Whereas research on social media has commonly addressed self-performance and impression management, we understand self-identity as an entity in progress. We analyze the results of two empirical case studies to suggest how and why a collapse of time related to self-performance is becoming increasingly prevalent, focusing on young people and Facebook. Our analyses contribute to a new understanding of time and the prolonged self-documenting practices typical of social media. Our research offers a unique understanding of the nature and conceptualization of time that may guide future directions in the study of social media and their implications for young people.

  Music-streaming services embed social features that enable users to connect to one another and use music as social objects. This paper examines how these features are experienced within negotiations of music as personal and social through the acts of sharing music and of following others. The analysis relies on 23 focus-group interviews with 124 Spotify or/and Tidal users, and a mixed-method study including music-diary self-reports, online observation, and interviews with 12 heavy users. Our findings suggest that users incorporate social awareness in non-sharing, selective-sharing, and all-sharing approaches with strong, weak, and absent ties. These ties are characterized by different configurations of social and music homophily. Negotiations of music as personal and social shape how music-streaming services are experienced

  In the current hyperconnected era, modern Information and Communication Technology (ICT) systems form sophisticated networks where not only do people interact with other people, but also machines take an increasingly visible and participatory role. Such Human-Machine Networks (HMNs) are embedded in the daily lives of people, both for personal and professional use. They can have a significant impact by producing synergy and innovations. The challenge in designing successful HMNs is that they cannot be developed and implemented in the same manner as networks of machines nodes alone, or following a wholly human-centric view of the network. The problem requires an interdisciplinary approach. Here, we review current research of relevance to HMNs across many disciplines. Extending the previous theoretical concepts of socio-technical systems, actor-network theory, cyber-physical-social systems, and social machines, we concentrate on the interactions among humans and between humans and machines. We identify eight types of HMNs: public-resource computing, crowdsourcing, web search engines, crowdsensing, online markets, social media, multiplayer online games and virtual worlds, and mass collaboration. We systematically select literature on each of these types and review it with a focus on implications for designing HMNs. Moreover, we discuss risks associated with HMNs and identify emerging design and development trends.

  Organizations aiming to foster civic engagement, such as government bodies, news outlets, political parties, and NGOs, struggle to purposefully use social media to engage young people. To meet this challenge and to inform future design, we interviewed 17 lead users, that is, representatives from organizations that are frontrunners in using social media to engage young people. In addition, we conducted four group-interviews with 21 youth, 16–26 years, about their experiences of and barriers to online civic engagement. Our paper contributes to identifying specific factors and strategies for how young people should be supported in future online civic engagement. Findings suggest that youth should be involved in collaboration within the organizations. Immediate feedback and dialogue combined with clearly stated goals and action-oriented engagement are important. In future design visual communication and design for use on mobile devices are important considerations, as well as concepts that connect between the online and the offline world. Finally, our paper contributes to an extension of the lead user innovation approach.

  In this paper we outline an initial typology and framework for the purpose of profiling human-machine networks, that is, collective structures where humans and machines interact to produce synergistic effects. Profiling a human-machine network along the dimensions of the typology is intended to facilitate access to relevant design knowledge and experience. In this way the profiling of an envisioned or existing human-machine network will both facilitate relevant design discussions and, more importantly, serve to identify the network type. We present experiences and results from two case trials: a crisis management system and a peer-to-peer reselling network. Based on the lessons learnt from the case trials we suggest potential benefits and challenges, and point out needed future work.

  This paper addresses how network characteristics affect collaboration in open innovation applications. Combining insights from open innovation and networked innovation, this paper applies an analytical framework addressing the innovation process from ideation to potential innovation, with a focus on relationships between involved parties and types of collective action. The analysis is based on the use of an open innovation application in three organizations: a hospital, an IT-company and three municipalities. Findings suggest that open innovation applications for gathering ideas facilitate a cross-cutting of vertical/hierarchical and horizontal/domain boundaries yet do little to alleviate challenges with innovation-management and cross-domain communication. Innovation-work beyond ideation, proceeding from an idea to an implemented innovation, is an example of high level collaboration, requiring high levels of commitment, reciprocal trust, common purpose, mutual benefits and risks. The ideation-phase and the later phases of the innovation-process hence benefit from different constellations of networks.

  Sosiale medier er en stadig viktigere kanal for kontakt med venner og familie. Likevel er eldre menneskers bruk og ikke-bruk av sosiale medier i liten grad forsket på. Ved hjelp av dybdeintervjuer (n=24), fokusgruppeintervjuer (n=39) og en spørreskjemaundersøkelse (n=290) undersøkte vi hvorfor noen eldre bruker, mens andre ikke bruker sosiale medier. Resultatene viser at typiske kjennetegn ved ikke-brukere er at de er "sent eldre" og har mindre sosiale nettverk enn de som bruker sosiale medier. Vi finner at ikke-bruk blant eldre ikke nødvendigvis er en konsekvens av kognitive svekkelser eller mangel på digital kompetanse, men heller et resultat av divergerende kommunikasjonskulturer, som gjenspeiler en generasjonskløft mellom en gammel og ny sosial verden. Ikke-brukerne opplever sosiale medier som kalde og flyktige. Den gruppen av eldre som bruker sosiale medier, har primært erfaring med Facebook. De bruker Facebook typisk som en kontaktkanal med familie og sine nærmeste venner. Et fellestrekk for brukerne er at har et større sosialt nettverk med flere nære ressurspersoner enn det ikke-brukerne har. Slik blir sosiale medier og Facebook mer relevant for denne gruppen, men også et sted hvor de sosialt rike eldre blir enda rikere.

  The verification of social media content and sources are increasingly critical to journalists and news organisations. In this study we report on findings from qualitative interviews conducted with 24 journalists working with social media in major news organizations in Europe. Our findings contribute to new knowledge on journalists' social media working practices. We find that social media content often are used as the primary news source, and journalists use several different verification strategies to verify social media content and sources. Journalists are also found to have various competences in verifying social media content, in particular visual content. Moreover, our study suggests user requirements for future innovations in tools to support the verification of social media content. To avoid trade-offs between verification and fast-paced publishing, journalists will need efficient and easy-to-use support both in the verification process and in structuring and organising an overwhelming amount of social media content

  Purpose – The purpose of this paper is to examine how the development and experimentation with a designer-assisted and collaborative concept-creating approach can provide new insights into the emergent field of service innovations. Design/methodology/approach – The paper were independent researcher with no commercial interests in the method investigated. The paper adopted qualitative methodology informed by 12 innovation workshop series among three Norwegian service companies, followed up by formative validation of the three years constructional and experimental period. Findings – The workshops introduced tangible tools and produced large numbers of innovation ideas, some of which were exploited. Participants internalized partially service design-terms and tools. The experimentation contributed to a common language among participants. Weaknesses included not explicitly addressing managerial learning and organization-internal issues. Research limitations/implications – New innovation interventions in the often fuzzy front-end should be validated to accumulate insights and allow changes. Practical implications – The paper offer a managerial framework for improving innovation experimentation among corporate employees and specialists. This will help companies understand service design impact on innovation by delineating key managerial components and limitations from broad business perspective. Social implications – Relationships influenced the construction and conduct of the innovation experiments, and consequently who were influenced by the experiment in the companies. To evaluate whom to include in the workshops and whom to represent by proxy innovation networks should be analyzed. Originality/value – This study reports one of very few appraisals of design-assisted service innovation interventions through process observations and follow-up field interviews, including interviews after the finalizing of field experiments. The paper offer frameworks and critical issues for fuzzy-end innovation practice and research.

  This paper presents the results from a qualitative study that examines managers' perspectives on open innovation platform (OIP) selection, focusing on their main criteria, requirements and needs. Six managers of a large company were interviewed about their experiences. This paper shows that platform selection is a combination of factors, and the creation of a company culture around OIP is very important in users' minds. Based on the results, we propose a list of selection criteria and dimensions for OIP classification. Our findings showed that criteria include ease of access, ease of innovation process, ease of integration and compatibility, as well as cost, fast, secure, differentiation for various user groups and the method of evaluating ideas. These results can be useful to support managers in their decision-making processes when selecting OIPs, in addition to helping platform designers and researchers.

  Though substantial research efforts have been spent on understanding the role of political party websites, there is a lack of in-depth knowledge con-cerning how such webpages are experienced by their users. In this paper, we present an interview study addressing users’ experiences of political party web-sites. Eleven users of a political party website were interviewed to explore their experiences with this website in terms of its features for information, engage-ment, mobilization, and interaction. The study contributes new understanding of how different features of political party websites affect users' experiences. In particular, our findings shed light on the importance of high-quality informa-tional content in political party websites for user engagement, and the role of features for interaction and dialogue relative to features for information. On the basis of our findings we offer lessons learnt relevant to the design and manage-ment of political party websites and suggest future research.

  While there has been a great deal of research on younger people using Social Networking Sites (SNSs), there has been less work on older people and non-users. We present a mixed-methods design with a technology-acceptance survey and focus group interviews, to study older Norwegian non-users' perceptions of SNSs. Our study reveals that most non-users in our sample deliberately do not use SNSs. They perceive SNS communication as cold and narcissistic, and view the usefulness of SNSs to be low. This finding indicates a generational culture gap in how young versus older experience SNSs. Privacy and security concerns are also prevalent. Non-users, expressing an interest in SNSs, believe SNSs could increase contact with family and friends, but perceive lack of competence to be a barrier.

  Social media are often argued to change political communication, decreasing the distance between politicians and citizens, and increasing citizens' influence on policymaking. This paper presents findings from a study of how the Norwegian Labour Party uses social media, focusing on the community platform MyLabourParty. Interviews with politicians and a survey with citizens as respondents were conducted to examine the experiences of online political discussions. Findings show that citizens and politicians expect MyLabourParty to strengthen citizen participation. Yet, citizens still experience communication asymmetry and politicians may find it challenging to participate to the extent citizens expect. Means for bridging the gap between expectations and experiences are called for, in particular redefinition of the offering, changes of user-practices, and system improvements.

  Online political debate is increasing in importance, both as a real world phenomenon and as an object of scientific study. We present a survey study exploring people’s motivations for engaging in online political debate and how such debate may impact their general political engagement. The survey was conducted among 90 participants of an online environment for political debate hosted by one of the main Norwegian political parties. We found four motivational factors with relevance for participation in online political debate: engaging topic, want to contribute, frustration, and reciprocal learning. Sixty-four per cent of the participants answered that the online environment for political debate could make them more politically engaged. These participants reported that such an increase in political engagement could be due to the online environment providing a sense of influence, access to political debate, a means for getting updated, a lowered threshold for participation, motivating local political engagement, and awareness concerning political events.

  Expectations on how social intranets will improve knowledge sharing and collaboration in enterprises are high. Yet research into user patterns of traditional SNSs demonstrates participatory divides, and differences in use can be expected with social intranets. In this paper we report on the findings from a study of the adoption–process of a social intranet into an international ICT company. Two archetypical users are described: the contributor and the reluctant user. This study suggests that different user–patterns will remain significant over time.

  This paper presents findings from an ethnographic study of communication and interaction in the MyOpera community. This community has evolved from a technical community to a social media arena. The transformation of MyOpera opens up for new types of users joining and participating, leading to improved user representations. We argue that user contributions and user interactions can lead to innovation, and that feedback and interaction in many situations can be seen as incremental innovations.

  Online collaborative writing applications might motivate children to write together and thus stimulate their learning and crativity. Although a lot of research has been done on collaborative tools in the professional context, little has been known on collaborative writing for children. This paper investigates which user experience factors stimulate children to write together. An application for collabrative writing has been evaluated with 35 school children. Based on the results of this evaluation we give a list of recommendation for design of such applications.

  The popularity of multimedia streaming services is rapidly increasing. In-depth knowledge of the users’ behaviour is one of the cornerstones of delivering optimal Quality of Experience in such services. In this paper, we present the results of three studies that investigate the patterns of users’ behaviour in Spain, Sweden, and Norway. Based on an analysis of the network traffic data and questionnaires from more than 270000 individual users and households, we identified user accesses over time as well as the users’ habits, preferences, and motivations. Our results show the stability of users’ behaviour across the countries and over time and the differences among the users and access types. The insights obtained in this study might provide valuable inputs for the design of future network management systems and multimedia streaming services.

  Open innovation software is regarded as valuable for involving users and stakeholders in service innovation. This paper discusses findings from a qualitative study where nine middlemanagers in a large service-company were interviewed about their experiences of an open innovation portal within their company. Results show that realizing the benefits of open innovation software demands: (1) that users see the value of participating; (2) an elaborate and reliable method for idea and innovation management; and (3) a strategy for leveraging the added value of networked innovation.

  During the last few years, personal and social media forms have blossomed online, attracting ever more users. Newsgroups, mailing lists, and MUDS (multiuser dungeons) in the 1980s and early 1990s were populated by a narrow segment of technologically interested Internet users. But email, instant messaging, blogs, photo- and video-sharing, and social network sites (SNSs) have become mainstream phenomena. In this chapter, (inter)personal tools for communication are labeled “personal media” to account for media forms that facilitate mediated interpersonal communication and personalized expressions (as a contrast to mass media) (see also Lüders, 2008 ). The success of online personal media seems to reflect a human willingness to embrace tools that support social interaction between offline meetings (just as we have previously embraced letters and telephones) (see Licoppe & Smoreda, 2005 ). Whereas diaries, letters, telephones, and snapshot photography are also examples of personal media, the focus here is on online personal media, as their networked qualities suggest important changes if compared to the historical significance of the analogue antecedents. These changes and the growing importance of online sociability, particularly among young users (as suggested by e.g. Henderson & Gilding, 2004 ; Lenhart et al., 2007 ; Lewis & Fabos, 2005 ; Ofcom, 2008

  In this article we argue that the concept of genre has a valuable function within sociological theory, particularly for understanding emerging communicative practices within social and personal media. Genres span the whole range of recognizable forms of communication, play a crucial role in overcoming contingency and facilitate communication. Their function is to enhance composing and understanding of communication by offering interpretative, recognizable and flexible frames of reference. As such, genres generate a sense of stability in modern complex societies. Genres ought to be seen as an intermediary level between the levels of media and text, however influenced by both. They operate as interaction between two interdependent dimensions, conventions and expectations, both of which are afforded by media and specific texts. In this article these relationships are illustrated through two cases of emerging personal media genres: the online diary and the camphone self-portrait.

  Mediated interaction plays a significant role in the social life of adolescents in Norway. The purpose of the present article is to examine the qualities of mediated interaction and the integration of mediated and immediate social spheres, suggesting that the ability to juggle between online and offline social spheres has become a characteristic element of social competence in network societies. More specifically, the analysis looks at the use of personal media for maintaining and developing existing social relationships and for extending social networks. Qualitative interviews with 20 Norwegian adolescents constitute the empirical base. The analysis explains how interaction takes on mundane forms, confirming the value of social relationships between in-person meetings. Moreover, it is argued that mediated communication differs from face-to-face communication, not by being less meaningful, but by enabling other forms of disclosing practices. Mediated forms of communication, hence, have an influence on the character of social ties and networks.

• Brandtzæg, Petter Bae; Lüders, Marika & Følstad, Asbjørn (2017). HOW TO UNDERSTAND TRUST IN NEWS MEDIA – A THEORETICAL MODEL. Vis sammendrag

  Trust in news media is critical in the everyday workings of a living democracy. However, several studies indicate that this trust is low or dwindling. Little is also known about how to understand and measure trust in this new and multifaceted media landscape. The objective of this paper is, therefore, to develop a theoretical model for understanding the components and nature of trust in news media, and show how professionals can use this model to predict and evaluate trust. The model is a modified version of Mayer, Davis, and Schoorman’s (1995) well-known model of interpersonal trust in organizations. Their model was one of the first to conceptualize trust as a dynamic and multidimensional concept, where trust is seen as particularly relevant for circumstances characterized by perceived risk. Due to significant changes in patterns of news consumption, we acknowledge and study how trust and trust antecedents vary across news organizations and different social contexts. In addition, our model of trust address a digital context with increasingly fragmented news media outlets, user groups, and changing media habits. The purpose of the proposed theoretical model is to adequately reflect citizen-diversity with factors determining specific "news media user types", and subsequently be able to examine user types as a moderating construct on trust and the trust antecedents. We address three different layers of factors that are likely to determine the type of news media users, such as individual attitudes or political preference, social or organizational networks, and culture or society.

  When designing for sharing online we need to gain a better understanding of what kinds of sharing practices that exists online, and how these sharing practices means in respect to differences in motivation and demands up on the giver versus the receiver. This paper explores the possibilities to develop a preliminary framework to; 1) understand the different sharing practices online and; 2) to provide a distinction between the receiver and the giver in regard to both motivations and demands in the sharing economy. The latter points to the fact that the different sharing practices online mainly focus on the person or group who holds the content or artefact to be shared (the giver). We also suggest that we should focus on the audience of the sharing practice. The other side of these sharing processes, the receiver of the content or artefact and the audience, has been largely ignored in the literature of sharing economy. Future directions and research challenges are discussed.

  Denne rapporten oppsummerer resultatene fra surveyundersøkelsen som ble gjennomført i august 2015 for å undersøke status og markedspotensial for kunde-til-kunde gjenbrukstjenester i Norge. Surveyen er besvart av 807 landsrepresentative respondenter fra Norstats Internettpanel. Per i dag er nettbaserte gjenbrukstjenester mest populære blant voksne mennesker i 30- og 40-årene med hjemmeværende barn. For å utvide markedspotensialet for større deler av befolkningen anbefales følgende: Utnytt den sterke appellen tjenestene har for å bli kvitt ting man ikke lenger trenger. Legg til rette for mer automatiserte, men likevel trygge transaksjoner. Vurder å utvikle personaliserte anbefalinger basert på likes/hjerter og følgefunksjoner for å hjelpe forbrukere å finne tingene de er interessert i. For forbrukere både som selgere og kjøpere er videre både tillit og sosial påvirkning viktig for fremtidige intensjoner om bruk av slike tjenester.

• Lüders, Marika; Haugstveit, Ida Maria & Følstad, Asbjørn (2015). Designing green consumption services for the mass market. Vis sammendrag

  We live in a time of increasing environmental awareness. For decades, the limits to growth in production and consumption at the expense of finite global resources have been addressed at a high political level. Yet, we seem challenged both to check this growth pattern and to deal with its environmental consequences. There is a lack in large-scale uptake of environmentally friendly consumption patterns, something that is particularly striking given the growing availability of green alternatives. Catchphrases such as collaborative consumption and the sharing economy epitomize the expected turn to sharing services and consumer-to-consumer (C2C) marketplaces. Nevertheless, the effect of these services on consumers' consumption patterns is nowhere near enough to check, for example, the growth in the consumption of new products. Within the field of service design, it is argued that environmental challenges may be perceived as design challenges. In this paper, we will explore how the design of services can help reduce the environmental impact of consumption. We will in particular consider services for C2C reselling and sharing which, while promising, still remain niche services either in the sense of being taken up by only a small proportion of the consumer market or in the sense of being used only infrequently by the majority of its users. While some niche services are truly valuable as lighting house examples of the feasibility and potential benefits of C2C sharing and reselling, the impact of these services is small compared to the impact of mass market services. Therefore, we argue that the key design challenge is to transform such niche services to mass-market services, where C2C sharing and reselling is considered the default option for mass market consumption. Hence, effort needs to be made not to make these services attractive for environmentally aware consumers, but to move them from their current status as niche phenomena to true mass market phenomena. To expand on this argument, we make a brief review of the literature on customer experience to explore market mechanisms that may enable such a transition for current reselling and sharing services. In the current literature on sustainable services, it is shown that a major barrier for increased use of such services is that they are often perceived as having lower functional or experiential value than that of non-green alternatives, for example being more expensive, less accessible, or more cumbersome to use. Because of this, we will explore how an increased consideration of the functional and experiential value of sustainable services may facilitate their transition from niche to mass market services. Following the literature review, we will present brief case descriptions of two such services, both associated with a research project on sustainable consumption. The first of these services, an online service for C2C reselling of used goods, is an example of how the value proposition of C2C marketplaces may be improved. The second, a company that buys discarded mobile phones and tablet computers and resells these on the second-hand market, is an example of the challenge of trust when reusing ICT. The cases and literature review is based on research conducted within the Conserve and Consume project (2014-2018; https://conserveandconsume.wordpress.com/).

  Social media are increasingly used as a news source by journalists all over the world. To ensure credibility and gain the public’s trust, the verification of social media content and sources is critical to journalists and news organisations. We report on findings from qualitative interviews conducted with 24 journalists working with social media in major news organizations in Europe. We identified five working practices concerning the verification of social media content and sources. Further, we found that fast-paced news publishing in an environment with information overload is perceived as a key challenge for journalists. To avoid trade-offs between verification and fast-paced publishing, journalists need efficient and easy-to-use support both in the verification process and in structuring and organising an overwhelming amount of social media content. Our findings contribute new knowledge on journalists' social media working practices and suggest user requirements for future innovations in tools to support the verification of social media content.

Det primære datagrunnlaget er intervjuer med 11 lokallagsbrukere av Mitt Arbeiderparti. I tillegg har vi gjennomført intervjuer med intervjuet soneansvarlige i tre soner, samt gjennomført nettverksanalyser og sjangeranalyser basert på innholdet i tre soner. Resultatene viser at den viktigste rollen for Mitt Arbeiderparti spiller en pr. i dag er sentral og viktig rolle som informasjonskanal. Deltagerne Brukerne forventer å finne relevant og oppdatert informasjon om Arbeiderpartiets politikk på nettsidene, og opplever at Mitt Arbeiderparti har en særlig viktig intern-politisk funksjon. Mitt Arbeiderparti er bygget opp som et sosialt nettsted, men deltagerne deltar i liten grad med egne kommentarer og innspill. Lav aktivitet skyldes blant annet at lokallagssonene i liten grad inviterer og inspirerer til debatt, samt at deltagerne ikke helt vet hvor de kan delta med egne innlegg. Både i Det er betydelige navigasjonsutfordringer både i forhold til informasjon og aktiv deltagelse. Oppdragsgiver: Norges Forskningsråd, VERDIKT-programmet

  Målsetningen med studien Seniorer og sosiale medier er å undersøke bruksmønstre for sosiale medier blant seniorer (alder 55+). Rapporten er utarbeidet på bakgrunn av 899 respondenter. Utvalget er gjort ved selvseleksjon, og resultatene er derfor ikke representative for seniorer generelt. 53 prosent av respondentene har brukt Facebook. Andre tjenester blir benyttet av svært få respondenter. Manglende interesse, behov, kunnskap og tid oppgis oftest som grunner til ikke å bruke sosiale medier. Ikke-brukere kan videre deles inn i tre grupper: 1) seniorer som er kritiske til sosiale medier; (2) seniorer som ikke opplever sosiale medier som relevante; og (3) seniorer som gjerne vil bruke sosiale medier, men som ikke opplever at de har kompetanse til det. I studien er det gjennomført en akseptanalyse. Denne viser at oppfattet nytte/verdi er den faktoren som har størst betydning for hvorvidt seniorer ønsker å bruke eller allerede bruker, sosiale medier. Tillit mht. personvern er også viktig.

  Mitt Arbeiderparti er Arbeiderpartiets nettsider for politisk diskusjon som skal favne bredden av partiets medlemmer og andre politisk interesserte. For å få kunnskap om hvordan deltagerne på Mitt Arbeiderparti opplever sin deltagelse, ble det gjennomført en spørreskjemaundersøkelse blant personer som hadde deltatt i diskusjoner her. I alt 90 personer deltok (44 prosent av de inviterte). Deltagerne var jevnt over eldre enn det som er typisk for nettsamfunn, med noe flere menn enn kvinner. Drøyt halvparten oppga å være medlem av et politisk parti; mindre enn en femdel å delta på politiske møter. Deltagerne synes i hovedsak å være positivt motivert til å delta i diskusjoner på Mitt Arbeiderparti, men en drøy tidel oppga frustrasjon som motivasjon. Mer enn halvparten av deltagerne oppga også at Mitt Arbeiderparti kan bidra til å øke deres politiske engasjement. Mer enn en tredjedel av deltagerne uttrykte, uten å direkte bli spurt om dette, et ønske om økt grad av respons og engasjement fra Arbeiderpartiet i diskusjonene på Mitt Arbeiderparti. Dette er blant de viktigste funnene i undersøkelsen, og danner grunnlag for fire anbefalinger til videre arbeid med hvordan Arbeiderpartiet bruker Mitt Arbeiderparti:(A) Arbeid målrettet med å senke partimedlemmenes terskel for å delta i diskusjoner på Mitt Arbeiderparti og skape kultur for slik dialog med den jevne politisk interesserte. (B) Synliggjør formålet med diskusjonene og hvordan innspill benyttes. (C) Vær åpne og søkende i diskusjonene. (D) Gjør åpent tilgjengelige oppsummeringer av prioriterte diskusjoner.

  Bruken av sosiale medier har hatt en eksplosiv utvikling, og innebærer et fundamentalt skifte i vår måte å kommunisere på. Dette gjør at samfunnet må tenke og jobbe på en ny måte, og reiser debatt om hvordan vi skal se på brukerne av offentlige tjenester. Sosiale medier har skapt en deltakelses- og delekultur karakterisert av åpenhet, erfaringsutveksling og samarbeid. På kommunalt nivå kan sosiale medier skape nye og bedre kommunikasjonsarenaer, der avstanden mellom kommunen og innbyggerne reduseres, og der innbyggerne selv blir viktige bidragsytere av relevant informasjon. Dette kan igjen bidra til et bedre tjenestetilbud. I dette foredraget presenteres konkrete eksempler på hvordan kommunens innbyggere kan involveres som viktige aktører i en åpen innovasjonsstrategi. I tillegg diskuteres retningslinjer for åpen innovasjon, deltakelse, dialog og erfaringsutveksling.

  I løpet av kort tid har nye sosiale medier endret både på teknologiske muligheter og kommunikasjonsmønstre oss imellom. Dette har igjen forandret betingelsene for person- og forbrukervern. Brukerne er blitt innholdsprodusenter og frigir stadig flere opplysninger om seg selv, og for mange flyttes privatlivet i økende grad ut på Internett. Personopplysninger har med ett blitt ”handelsvare”.SINTEF har ved hjelp av en spørreundersøkelse og gjennom intervjuer både med utviklere og brukere skaffet kunnskap om befolkningens erfaringer og holdninger til person- og forbrukervern i sosiale medier. Resultatene viser at 67% av nettbrukerne er bekymret for konsekvensene av å dele personlig informasjon på Internett. I tillegg viser studien at nettbrukere flest har en begrenset innsikt i hvordan sosiale medier fungerer. Utviklere av sosiale medier tror på sin side at personvernet reguleres av brukermakten, siden tjenestene er avhengig av brukernes tillit, og mener slik at forbrukervernet ikke er nevneverdig svekket. Rapporten belyser videre at 66 % av nettbrukerne i Norge er brukere av nettsamfunn, og 35 % er daglige brukere av Facebook.Èn konklusjon er at bruk av Facebook gir et relativt dårlig personvern. Både kjennetegn ved selve tjenesten, designet, brukernes kompetanse og manglende bevissthet i forhold til forbruker- og personvern, understreker dette. 36 % av nettsamfunnsbrukerne rapporterer det som utrygt å dele personlig innhold med andre i det nettsamfunnet de bruker oftest. Vi finner også at brukerne ikke forstår brukervilkårene for gratistjenester som Facebook. Flere kvinner enn menn bruker Facebook, de bruker det oftere og de har andre og mer ”private” brukerpreferanser enn menn, og kan slik sett være mer sårbare enn menn.Et annet funn er at majoriteten av brukeren (63%) ikke ønsker skreddersydd, målrettet reklame, noe utviklerne av disse tjenesten tror at de ønsker. Dette funnet korresponderer med en tilsvarende studie nylig utført i USA. Oppdragsgiver: Forbrukerrådet

  Foredraget gir en kritisk diskusjon av den økende tendensen til å inkludere brukerskapte elementer og til å involvere publikum som innholdsprodusenter. Det argumenteres for at selv om deltakerkulturen er verdifull, bør ikke massemedieaktørene se seg blinde på brukerinvolvering. Massekommunikasjonen har aldri vært avhengig av symmetriske kommunikasjonsformer for å fungere, snarere tvert i mot. Forskjellene mellom massekommunikasjon og mer personlige kommunikasjonsformer diskuteres ut fra interaksjon, deltakelse og sosial integrasjon.
