Investigating the effect of attributs on user trust in social media

One main challenge in social media is to identify trustworthy information. If we cannot recognize information as trustworthy, that information may become useless or be lost. Opposite, we could consume wrong or fake information - with major consequences. How does a user handle the information provided before consuming it? Are the comments on a post, the author or votes essential for taking such a decision? Are these attributes considered together and which attribute is more important? To answer these questions, we developed a trust model to support knowledge sharing of user content in social media. This trust model is based on the dimensions of stability, quality, and credibility. Each dimension contains metrics (user role, user IQ, votes, etc.) that are important to the user based on data analysis. We present in this paper, an evaluation of the proposed trust model using conjoint analysis (CA) as an evaluation method. The results obtained from 348 responses, validate the trust model. A trust degree translator interprets the content as very trusted, trusted, untrusted, and very untrusted based on the calculated value of trust. Furthermore, the results show a different importance for each dimension: stability 24%, credibility 35% and quality 41%

Acceptability and Use of Mobile Health Applications in Health Information Systems: A Case of eIDSR and DHIS2 Touch Mobile Applications in Tanzania

Part 2: Digital Platforms for DevelopmentInternational audienceThe use of modern information and communication technology plays a significant role in healthcare services improvement. In the recent years, various mobile application systems have been deployed in the health sectors of different developing countries to facilitate remote data collection and transmission so as to improve its quality and availability. Consequently, understanding the factors contributing to mobile technology acceptance is imperative. The purpose of this study was to adopt a modified UTAUT theoretical model to understand the factors influence acceptance and use of mobile health applications by health workers at health facilities in Tanzania. Questionnaires were used to collect data from health facilities workers. Out of 150 health facilities workers, only 108 return, a 72% return rate whose data was statistically analyzed using SPSS tool. The findings show that effort expectancy and facilitating conditions significantly influence the users located in the urban area on behavioral intention to use mobile health applications. Furthermore, the study shows that the constructs such as social influence, training adequacy, and voluntariness of use do not have a significant influence on the use of mobile health applications

United we stand ::exploring the notion of cooperation support system for business model design

In this chapter, we identify possible connections between the notion of co-utility and new business models, which are based on cooperation among consumers. We start with known cases of sharing economy (Uber and AirBnB) to introduce the business model canvas as a tool to support the design of right incentives for cooperation among stakeholders. Then we use the business model canvas to illustrate two research projects and two real-life applications focused on a transportation firm and a boutique hotel

Stadsplaneringsprocessen i förändring

Bostadsbristen i Stockholm har lett till en debatt om hur planprocessen för byggnation kan effektiviseras och hur mycket denna effektivisering får kosta. Debatten inleds av Statens offentliga utredningar, SOU 2013:34 där det punktas upp förslag på hur planprocessen kan tidseffektiviseras. Förespråkare av denna typ av effektivisering anser att en bra lösning är att minska på medborgarnas möjligheter att överklaga planer. På den andra sidan i debatten återfinns organisationer som menar att medborgarnas åsikter är av högsta relevans och menar istället att en ökad möjlighet för medborgarna att delta i planprocessen kan bidra till demokratiska fördelar. För att undersöka debatten kring planprocessen, effektivitet och medborgardeltagande, har tidningsartiklar, branschtidningen PLAN, en bok utgiven av tre professorer på KTH samt tre olika statliga utredningar studerats. Studien har en diskursanalytisk karaktär, då själva debatten och hur den framställs är studerad istället för att fokus ligger på att fånga in en statisk bild av samhället. För att förklara de olika argumenten, har de relaterats till olika demokratimodeller tillsammans med Arnsteins stege, vilken förklarar olika grader av medborgardeltagande. Resultatet av studien är att planprocessen är i ständig förändring. För tillfället överväger de röster i debatten som förespråkar tidseffektivisering
