  4. 3. Firefighters' physical work capacity

    Författare :Ann-Sofie Lindberg; Christer Malm; Juha Oksa; Desiree Gavhed; Peter Krustrup; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical demands; performance; work capacity; aerobic fitness; anaerobic fitness; muscle strength; muscle endurance; balance; ergonomics; physical testing; SIMCA;

    Sammanfattning : The overall aim of this thesis was to identify valid, simple, and inexpensive physical tests that can be used for evaluation of firefighters’ physical work capacity. Paper I included fulltime- and part-time firefighters (n = 193), aged 20-60 years. LÄS MER

  5. 4. The second wave : the Urak Lawoi after the tsunami in Thailand

    Författare :Ann-Charlotte Granbom; Christer Lindberg; Thomas Malm; Peter Ian Crawford; Sweden Lund University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Urak Lawoi; Chao Ley; sea nomads; sea gypsies; sea people; Thailand; disaster; vulnerability; resilience; tourism development; land policies; Indigenous people; Religion; Urak Lawoi; Turismvetenskap; Tsunami; landrättigheter; Thailand; Havsnomader; ursprungsfolk; visuell antropologi; havsfolk; sårbarhet; religion;

    Sammanfattning : Urak Lawoi är en ursprungsbefolkning i Andamansjön som bl.a. bor på kända turistöar som Phuket, Phi Phi, Ko Lanta Yai och Ko Lipe utanför Thailands västkust. Deras språk och kultur skiljer sig från övriga thailändares, inte minst ifråga om kunskap att navigera på havet. LÄS MER

  7. 5. Experience feedback in practice
