    Sammanfattning : Using data from long-term studies of the vegetation in two areas under primary succession, patterns of colonisation and the accumulated seed bank during plant succession were studied.At century-old small islands in Lake Hjälmaren, Sweden, the genetic structure of differently old populations of Moehringia trinervia and Lythrum salicaria was studied, using allozyme variation for M.

  3. 2. Health effects of heatwaves : short and long term predictions

    Författare :Christofer Åström; Bertil Forsberg; Kristie L. Ebi; Scott Sheridan; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heatwave; health impact assessment; early warning system; mortality; morbidity; climate change;

    Sammanfattning : Background: Climate change is defined by the Intergovernmental Panel on Climate Change as changes in the state of the climate associated with changes in the mean and/or the variability of its properties. Climate change will affect temperatures both as an increase in mean temperature as well as changes in the frequency of temperature extremes. LÄS MER

  4. 3. SEA CHANGE : Social-ecological co-evolution in Baltic Sea fisheries

    Författare :Jonas Hentati-Sundberg; Henrik Österblom; Joakim Hjelm; Trevor Branch; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; resilience; social-ecological systems; complex adaptive systems; fisheries; Baltic Sea; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : Sustainable management of natural resources requires an in-depth understanding of the interplay between social and ecological change. Linked social-ecological systems (SES) have been described as complex adaptive systems (CAS), which mean that they are irreducible, exhibit nonlinear dynamics, have interactions across scales and are uncertain and unpredictable.

  5. 4. Exploring the sustainability of improvement activities : the long-term development of a suggestion scheme

    Författare :Cecilia Rapp; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Continuous improvements; Change; Survival; Longevity;

    Sammanfattning : The practice of working with improvement activities is widespread in organisations today. Improvement activities are part of the new ISO 9000 standard, and could be in the form of Six Sigma programs, suggestion schemes, or process orientation, for example. LÄS MER

  7. 5. Time to change : zipping sustainability into operations

    Författare :Anna Sannö; Deleryd Mats; Carsten Reuter; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sustainable operations; environment; technological change; Innovation and Design; innovation och design;

    Sammanfattning : Industry is a key player in the transition to a sustainable society, where manufacturing companies need to respond to the challenges of environmental concerns in several ways. The need for managing environmental technological change in production systems is and will continue to be a challenge for manufacturing companies, as they often tend to focus on short-term priorities to stay economically competitive, rather than developing the organisation to manage longer-term environmental competitiveness.
