  1. 1. Combining cognitive and physical work tasks: Short-term effects on fatigue, stress, performance and recovery

    Författare :Susanna Mixter; Svend Erik Mathiassen; David Hallman; Petra Lindfors; Paul Jarle Mork; Högskolan i Gävle; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; physical; repetitive; cognitive; mental; load; variation; job rotation; restoration; allostatic load; fysisk; repetitiv; kognitiv; mental; belastning; variation; arbetsrotation; återhämtning; allostatisk belastning; Health-Promoting Work; Hälsofrämjande arbete;

    Sammanfattning : Background: Although combinations of physical and cognitive work tasks occurs in working life (both concurrent and alternating), no one has summarized the research regarding such combinations. Very few studies have investigated the effects of alternating physical and cognitive tasks, which have been suggested as an alternative to classic job rotation. LÄS MER

  3. 2. Methods to assess physical load at work : With a focus on the neck and upper extremities

    Författare :Peter Palm; Mikael Forsman; Magnus Svartengren; Svend Erik Mathiassen; Eva Vingård; Esa Pekka Takala; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; risk assessment; physical load; upper extremities; ergonomics; Occupational and Environmental Medicine; Arbets- och miljömedicin;

    Sammanfattning : To prevent work-related musculoskeletal disorders (MSDs), useful, reliable and valid methods for assessing physical workload and risks for MSDs are needed. Ergonomists often assess work by short visual observations without a specific tool. LÄS MER

  4. 3. Tracing environmental change and human impact as recorded in sediments from coastal areas of the northwestern Baltic Proper

    Författare :Lena Norbäck Ivarsson; Elinor Andrén; Thomas Andrén; Mikael Lönn; John Anderson; Södertörns högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; paleoecology; diatom stratigraphy; stable nitrogen isotopes; hypoxia; nutrient discharge; eutrophication; Medieval Climate Anomaly; Little Ice Age; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Sammanfattning : The eutrophication of the Baltic Sea due to increased anthropogenic nutrient loads during the 20th century is well documented and studied. However, in the Baltic Sea drainage area, humans have affected the environment longer than the environmental monitoring can provide data for. LÄS MER

  7. 5. Physical load, psychosocial and individual factors in visual display unit work

    Författare :Jens Wahlström; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; computer work; musculoskeletal symptoms; working; technique; psychosocial factors; physical load; muscular tension; mental; stress;

    Sammanfattning : The overall aim of this thesis was to explore associations between physicalload, psychosocial and individual factors in visual display unit (VDU)work. Furthermore, the aim was to investigate whether perceived musculartension is a predictor of neck pain among VDU operators. LÄS MER
