  4. 22. Social Awareness Support for Cooperation : Design Experience and Theoretical Models

    Author : Ovidiu Sandor; Yngve Sundblad; Cristian Bogdan; Steven Benford; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; HCI; CSCW; social awareness; user-centred design; Spatial Model; Aether Model; communities; knowledge; Computer science; Datavetenskap;

    Abstract : This thesis addresses the research question of how social awareness support in computer systems for groups and communities can be designed in a successful way. While the field of human-computer interaction has been working with similar questions for more than 20 years, many aspects of people’s cooperation and the way those should be considered in system design still need further consideration and research.

  5. 23. Univariate and Multivariate Surveillance of Outbreaks

    Author : Linus Schiöler; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; change-points; expected delay; exponential family; false alarms; generalised likelihood; inference principles; influenza; MEWMA; monitoring; multivariate; ordered regression; performance metrics; outbreak; predictive value; subjective judgment; spatial; statistical models; surveillance; tularemia;

    Abstract : In many areas there is a need to monitor observations in order to detect changes in the underlying processes as quickly as possible. The theory of statistical surveillance provides the possibility of making optimal decisions about whether a change has occurred or not based on the data available at the time of the decision.

  7. 25. A Spatial Scale Approach to Fish Habitat Ecology and Impacted Rivers

    Author : Henry H. Hansen; Eva Bergman; Max Lindmark; Dana Infante; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fish Habitat Models; River Ecology; Novel Riverscapes; Spatial Scale; Fish Communities; Anthropogenic Impacts; Sustainability; River Management; River Restoration; Biology; Biologi;

    Abstract : Fish biodiversity in rivers is threatened by continual habitat loss. Evidence to support management and restoration of rivers requires information about the specific habitat requirements for entire fish communities. READ MORE
