    Abstract : Abstract Noroviruses are now the leading cause of gastroenteritis worldwide. Noroviruses are effectively transmitted due to a low infectious dose, viral shedding in high concentrations, environmental stability, and they induce only a limited immunity after infection. Especially, the norovirus variants of genotype II.4 (GII. READ MORE

  2. 2. Univariate and Multivariate Surveillance of Outbreaks

    Author : Linus Schiöler; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    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.

  3. 3. Resistance and recolonization of bryophyte assemblages following disturbances : - detecting patterns and exploring mechanisms

    Author : Martin Schmalholz; Kristoffer Hylander; Jari Kouki; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Bryophytes; boreal forest; boulders; clear-cutting; disturbance; establishment; insect outbreaks; microtopography; recolonization; resistance; spatial heterogeneity; succession; wildfires; Biology; Biologi; Plant Ecology; växtekologi;

    Abstract : Disturbances are ubiquitous features of most northern forest ecosystems. The subsequent response of plant assemblages on both short (resistance or not) and long term (recolonization or not) will depend on a number of factors operating at several spatial scales. READ MORE

  4. 4. HIV/AIDS in Sweden and the United Kingdom : policy networks 1982-1992

    Abstract : The focus of this study is on the development and influence of HIV/AIDS policy networks in Sweden and United Kingdom during the period 1982-92, from the period when the lethal disease which was later named AIDS first appeared in the two countries, to the time when HIV/AIDS policy was integrated into the main policy field of infectious diseases. The networks are defined as structural arrangements between organisations and individuals, who are in frequent contact with one another in order to prevent HIV infection, to reduce the personal and social impact of HIV infection, and to care for those already infected.
