  1. 1. Univariate and Multivariate Surveillance of Outbreaks

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Linus Schiöler; Göteborgs universitet.; Gothenburg University.; [2010]
    Nyckelord :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;

    Sammanfattning : 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.

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

    Detta är en avhandling från Stockholm : Department of Botany, Stockholm University

    Författare :Martin Schmalholz; Stockholms universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bryophytes; boreal forest; boulders; clear-cutting; disturbance; establishment; insect outbreaks; microtopography; recolonization; resistance; spatial heterogeneity; succession; wildfires; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi; växtekologi; Plant Ecology;

    Sammanfattning : 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. LÄS MER

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

    Detta är en avhandling från Stockholm : Department of Political Science, Stockholm University

    Författare :Dagmar von Walden Laing; Stockholms universitet.; [2001]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HIV infections epidemiology; HIV infections prevention contro; l Acquired immunodeficiency syndrome epidemiology; Acquired immunodeficiency syndrome prevention control; Disease outbreaks; Communicable disease control; Sweden; Great Britain; AIDS; HIV; politiska aspekter; Sverige; Storbritannien; statsvetenskap; Political Science;

    Sammanfattning : 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.

  4. 4. Detection and epidemiologic subtyping of Legionella pneumophilia using DNA-based molecular methods

    Detta är en avhandling från Stockholm : Karolinska Institutet, Microbiology and Tumor Biology Center (MTC)

    Författare :Sverker Bernander; Karolinska Institutet.; Karolinska Institutet.; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Legionella; AFLP; PFGE; Nested PCR; lag-1; hospital; outbreaks;

    Sammanfattning : Legionella pneumophila causes 2 - 6 % of hospitalised pneumonia cases. Several community- and hospital-acquired outbreaks have been reported over the years. Legionnaires' disease (LD) or legionellosis is also a frequent cause of pneumonia amongst travellers. LÄS MER

  5. 5. Monitoring insect defoliation in forests with time-series of satellite based remote sensing data - near real-time methods and impact on the carbon balance

    Detta är en avhandling från Department of Physical Geography and Ecosystem Science, Lund University

    Författare :Per-Ola Olsson; Lunds universitet.; Lund University.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Popular Abstract in Swedish Skogar är av stor betydelse ur klimatsynpunkt på grund av deras stora förmåga att binda kol. Skogar på de nordligare breddgraderna spelar en viktig roll med sitt stora kolupptag, men eftersom dessa nordliga skogar troligen kommer att påverkas av klimatförändringarna i hög grad är det osäkert hur framtida kolupptag kommer att utvecklas.
