Extensive Internet InvolvementâAddiction or Emerging Lifestyle?
In the discussions for the future DSM-5, the Substance-Related Disorders Work Group has been addressing âaddiction-likeâ behavioral disorders such as âInternet addictionâ to possibly be considered as potential additions for the diagnostic system. Most research aiming to specify and define the concept of Internet addiction (or: Excessive/Compulsive/Problematic Internet UseâPIU), takes its point of departure in conventional terminology for addiction, based in established DSM indicators. Still, it is obvious that the divide between characteristics of addiction and dimensions of new lifestyles built on technological progress is problematic and far from unambiguous. Some of these research areas are developing from the neurobiological doctrine of addiction as not being tied to specific substances. The concept of âbehavioral addictionsâ, based on biological mechanisms such as the reward systems of the brain, has been launched. The problems connected to this development are in this study discussed and reflected with data from a Swedish survey on Internet use (n = 1,147). Most Swedes (85%) do use the Internet to some degree. The prevalence of excessive use parallels other similar countries. Respondents in our study spend (mean value) 9.8 hours per week online at home, only 5 percent spend more than 30 hours per week. There are both positive and negative social effects at hand. Many respondents have more social contacts due to the use of Internet, but there is a decline in face-to-face contacts. About 40% of the respondents indicate some experience of at least one problem related to Internet use, but only 1.8% marked the presence of all problems addressed. Most significant predictors for problem indicators, except for age, relate to âtimeâ and time consuming activities such as gaming, other activities online or computer skills

Barn och ungas medieanvÀndning i Internet-vÀrlden
Nordicom fĂ„r varje dag frĂ„gor som rör ungas medieÂvanor och effekterna av nya kommunikationsmönster. Hur har dessa pĂ„verkat barn och unga? Vad har hĂ€nt med TV-tittandet, radiolyssnandet och tidningslĂ€sandet? LĂ€ser de unga fortfarande böcker och tidskrifter? Och förstĂ„r de vad de lĂ€ser? Vilka Ă€r de mest aktiva medieanvĂ€ndarna? Vilka stĂ„r utanför? FrĂ„gorna Ă€r mĂ„nga och inte sĂ€llan komplexa.Det handlar oomtvistat om ett nytt kommunikationssamhĂ€lle med nya kommunikationsmönster. Inte sedan televisionens introduktion för femtio Ă„r sedan har det skett sĂ„dana genomgripande förĂ€ndringar av de ungas mediekultur som under de senaste tio Ă„ren. Undersökningar som Nordicoms Mediebarometer och Internet och svenskarna frĂ„n World Internet Institute ger möjligheter till en fördjupad kunskap pĂ„ omrĂ„det.I rapporten Barn och unga i Internet-vĂ€rlden redovisar professor Olle Findahl resultat frĂ„n bearbetningar av dessa undersökningar. Han beskriver och analyserar förĂ€ndringarna under de senaste tio Ă„ren fram till idag och placerar Ă€ven in de ungas medievanor i ett lĂ€ngre samhĂ€lleligt perspektiv.Se Ă€ven Barn och ungas medieanvĂ€ndning i nĂ€tverkssamhĂ€llet, en ny uppdaterad och utvidgad utgĂ„va

User Oriented Business Models in Peer-to-Peer Services
A limited number of business and legal solutions have been used over the decades to solve the content industryâs "problems" arising from new technology. Content industry has been lagging behind technology developers especially when it comes to different file-sharing (Peer-2-Peer) technologies and systems. The paper shows that P2P technology will be necessary in the future. Research has shown that it is possible to group file-sharers in three major gropus â "free riders", "samplers" and "squirrells". Studying the properties of these groups a number of business models can be defined. This study show that business models such as licensing, subscription, retail and e-commerce models can be derived from these groups of users. This study also concludes that new underpinning technologies such as DRM and a natural language approach to content mark up are necessary to be able to develop solutions to make these business models satisfactory for both users and content owners.QC 20130424Musiclesson
