  1. 6. Hazard screening of contaminated sites : bioavailable fractions and biological in vitro tools

    Författare :Daniel Ragnvaldsson; Mats Tysklind; Per Leffler; Lars Lövgren; Bengt-Erik Bengtsson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hazard screening; bioavailability; metal pollution; in vitro cytotoxicity; water extraction; CCA; arsenic genotoxicity; genotoxicity; Contaminated soil; Environmental chemistry; Miljökemi;

    Sammanfattning : The environmental bioavailability of contaminants, rather than their total concentrations in the soil compartment play a decisive role for the risks associated with contaminated sites. Various soil constituents and abiotic conditions have strong influence on bioavailability, which may vary substantially between different locations. LÄS MER

  3. 7. Skälens fångar : Hemlöshetsarbetets organisering, kategoriseringar och förklaringar

    Författare :Marcus Knutagård; Socialhögskolan; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; institutional loop; rendering; sites; cathegorization; Homelessness; organizing; housing staircase; last resort; homeless;

    Sammanfattning : Category housing is an example of forms of housing that belong to the organized work of providing residences for persons who for diverse reasons cannot obtain them on the ordinary housing market. In the organizing of the practical social work that is carried out for this purpose, categorization serves as an important tool for connecting the available housing alternatives with the individuals who seek help in their residential situation.

  4. 8. Leetocracy : Political participation, social network sites and inequality

    Författare :Nils Gustafsson; Statsvetenskapliga institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; political participation; social network sites; social media; Web 2.0; political mobilization; social movements; political parties; democratic theory;

    Sammanfattning : This dissertation is about whether social network sites have the potential to bring about more equal participation. It deals with a phenomenon that has changed the underlying infrastructure of how millions of people communicate. LÄS MER

  5. 9. On Bayesian Decision Analysis for Evaluating Alternative Actions at Contaminated Sites

    Författare :Jenny Norrman; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; influence diagrams; Bayesian decision analysis; groundwater; data worth analysis; contaminated sites; decision analysis; risk analysis;

    Sammanfattning : Today, contaminated land is a widespread infrastructural problem and it is widely recognised that returning all contaminated sites to background levels, or even to levels suitable for the most sensitive land use, is not technically or financially feasible. The large number of contaminated sites and the high costs of remediation, are strong incentives for applying cost-efficient investigation and remediation strategies that consider the inherent uncertainties.

  7. 10. Investigating the Relation between Efficient, Effective and Sustainable Remediation of Contaminated Sites

    Författare :Robert Anderson; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; effective remediation; multi-criteria decision analysis; efficient remediation; decision support; sustainability assessment; cost-benefit analysis; contaminated sites;

    Sammanfattning : Remediation of contaminated sites reduces negative impacts to humans and the environment, but the process itself is typically associated with high costs to society and large environmental footprints. The sustainable remediation concept has, over the past decade, brought increased attention to the often-overlooked contradictory effects of site remediation. LÄS MER
