  2. 2. Upper Extremity Musculoskeletal Disorders In Female Machine milkers - An Epidemiological, Clinical and Ergonomic Study

    Author : Marianne Stål; Människan i rörelse: hälsa och rehabilitering; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biaxial eletrogoniometer; movements; wrist positions; pronator syndrome; median nerve entrapment; clinical examination; hands; wrists; upper extremity musculoskeletal disorders; agriculture; Cross-sectional study; female milkers; electromyography muscles of the forearm.; Occupational health; industrial medicine; Yrkesmedicin; arbetsmiljömedicin;

    Abstract : The aims of the thesis were to investigate the prevalence of the upper extremity musculoskeletal disorders in female milkers in relation to other occupational groups; to clarify the relationship between disorders and work environment, psychosocial and life style factors; to compare in a prospective study, pain, ache and discomfort reported by a questionnaire with clinical symptoms and sign; to examine milkers with wrist and hand disorders with regard to type and localization of the tissue injury; to quantify the work load on forearms, wrists and hands during machine milking. An increased risk developing symptoms in wrists and hands was noted in the active milker group compared to the non-milker and the nursing assistant group. READ MORE

  3. 3. Inertia and practice change related to greenhouse gas reduction : Essays on institutional entrepreneurship and translation in Swedish agri-food

    Author : Herman Stål; Karl Johan Bonnedahl; Jessica Eriksson; Peter Dobers; Umeå universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Inertia; climate change; sustainability; agriculture; institutional entrepreneurship; institutional logics; convergent change; divergent change; practice; translation; Tröghet; klimatförändring; hållbarhet; jordbruk; institutionellt entreprenörskap; institutionella logiker; konvergent förändring; divergent förändring; praktik; översättning; företagsekonomi; Business Studies;

    Abstract : To avoid dangerous climate change a massive reduction in greenhouse gas emissions is required in a relative short time span. However, as development is moving in the wrong direction, there appears to be great inertia in changing activities. READ MORE

  5. 5. Identifying Influential Observations in Nonlinear Regression : a focus on parameter estimates and the score test

    Author : Karin Stål; Tatjana von Rosen; Sune Karlsson; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Added parameter plot; differentiation approach; influential observation; nonlinear regression; score test; Statistics; statistik;

    Abstract : This thesis contributes to influence analysis in nonlinear regression and in particular the detection of influential observations. The focus is on a regression model with a known mean function, which is nonlinear in its parameters and where the function is chosen according to the knowledge about the process generating the data.
