Heim, Jan, Brandtzæg, Petter Bae, Kaare, Birgit Hertzberg and Endestad, Tor (2007): Children’s Usage of Media Technologies and Psychosocial Factors. In New Media And Society, 9 (3) pp. 425-454.

“Media use has changed considerably during the past five years and earlier research has produced contradictory results on how media use links to children's psychosocial factors. This study charts the access to and use of several media technologies among 825 Norwegian schoolchildren between 10 and 12 years of age. The questionnaire contained items concerning children's self-concept, parental monitoring and social competence. It found that children engage with different kind of media activities and some of these are significantly related to psychosocial factors, however, these correlations were in general quite small. Entertainment usage was associated with low scholastic competence. Both utility usage and heavy advanced usage of new media were related to self-perceptions of athletic competence. Low social acceptance was linked to Gameboy usage and advanced usage of media. Finally, there was a relationship between experienced parental monitoring and utility usage of media technology. The possible implications for these empirical relations are discussed. ”

Kaare, Birgit Hertzberg, Brandtzæg, Petter Bae, Heim, Jan and Endestad, Tor (2007): In the borderland between family orientation and peer culture: the use of communication technologies among Norwegian tweens. In New Media And Society, 9 (4) pp. 603-624.

“This article explores the use of mediated communication among Norwegian children aged between 10 and 12 years. The analysis is based on a survey and 88 qualitative interviews with 130 children about their use of different types of communication technologies. This allowed a sketch of connections between the nature of the childrens' social relationships, mediated content and various means of communication employed. Six main content categories of mediated communication were identified. The study points out that new media technologies offer the children new ways of communicating content and meaning which were not easily communicated by children before; both aggressive and emotionally positive content are exchanged more easily through digital technologies than face-to-face. Above all, the children use communication technologies to build and strengthen relationships for the benefit of their schoolmates and friends. Whether the use of new communication technologies, Short Message Service (SMS) in particular, is accelerating the ongoing process of individualization of the family, is discussed.”

Endestad, Tor, Holmstroem, Conny B. O. and Volden, Frode S. (1992): Effects of Using a Diagnostic Rule-Based Expert System Developed for the Nuclear Industry. In: Proceedings of the Human Factors Society 36th Annual Meeting 1992. pp. 1200-1204.

“This experiment, conducted at the OECD Halden Reactor Project, Halden, Norway in the spring 1991, aimed to assess the effect on nuclear power plant operators diagnostic behaviour when using a rule based diagnostic expert system. The rule based expert system used in the experiment is called DISKET (Diagnosis System Using Knowledge Engineering Technique) and was originally developed by the Japan Atomic Energy Research Institute (JAERI). The experiment was performed in the Halden man-machine laboratory using a full scope pressurized water reactor simulator. Operator performance in terms of quality of diagnosis is improved by the use of DISKET. The use of the DISKET system also influences operators problem solving behaviour. The main difference between the two experimental conditions can be characterised as while the DISKET users during the diagnosis process are following a strategy which is direct and narrowed, the non-DISKET users are using a much broader and less focused search when trying to diagnose a disturbance.”
