  1. 1. Mortality in Oxygen-Dependent Chronic Obstructive Pulmonary Disease and Possibilities for Pharmacological Interventions

    Författare :Magnus Ekström; allergologi och palliativ medicin Lungmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; COPD; mortality; survival; comorbidity; cardiovascular disease; cardiovascular drugs; angiotensin-converting enzyme inhibitor; angiotensin receptor blocker; beta blocker; statin; aspirin; antiplatelet drug; gender; sex; oxygen-dependent; LTOT; trends; excess mortality; SMR; hypoxemia; hypoxia; hypoxaemic;

    Sammanfattning : Background Chronic obstructive pulmonary disease (COPD) is a major and rising cause of mortality worldwide, especially in women. Patients with chronic hypoxia owing to COPD are treated with long-term oxygen therapy (LTOT) but have high morbidity and mortality. LÄS MER

  3. 2. Maximum spacing methods and limit theorems for statistics based on spacings

    Författare :Magnus Ekström; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Estimation; spacings; maximum spacing method; consistency; ^-divergence; goodness of fit; unimodal density; entropy estimation; uniform distribution;

    Sammanfattning : The maximum spacing (MSP) method, introduced by Cheng and Amin (1983) and independently by Ranneby (1984), is a general estimation method for continuous univariate distributions. The MSP method, which is closely related to the maximum likelihood (ML) method, can be derived from an approximation based on simple spacings of the Kullback-Leibler information. LÄS MER

  4. 3. Enabling and Coercive Control : Coexistence in the Case of Banking

    Författare :Cecilia Ekström; Tobias Johansson; Gabriella Wennblom; Magnus Hansson; Anders Hersinger; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Enabling control; coercive control; coexistence of control; attitudinal outcomes of control; management control; regulation; banking;

    Sammanfattning : This thesis focuses on subjects of control and attitudinal outcomes of formalized control in organizations. Previous research have concluded contradicting results of whether formalized control is positive or negative for the employees and propose that not only degree of formalization, but also type of formalization, can explain attitudinal outcomes.

    Sammanfattning : I avhandlingen analyseras hur våldsutsatta kvinnors behov tolkas, omförhandlas och anpassas för att kunna hanteras inom socialtjänstens organisation. Avhandlingens övergripande frågeställningar fokuserar på insatser och behov, betydelsen av socialtjänstens organisering och betydelsen av socialarbetarnas handlingsutrymme. LÄS MER

  7. 5. Methods for interval-censored data and testing for stochastic dominance

    Författare :Angel G. Angelov; Magnus Ekström; Maria Karlsson; Bengt Kriström; Per Johansson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Interval-censored data; Informative censoring; Self-selected intervals; Questionnaire-based studies; Maximum likelihood; Permutation test; Two-sample test; Stochastic dominance; Four-decision test; Statistics; statistik;

    Sammanfattning : This thesis includes four papers: the first three of them are concerned with methods for interval-censored data, while the forth paper is devoted to testing for stochastic dominance.In many studies, the variable of interest is observed to lie within an interval instead of being observed exactly, i.e. LÄS MER
