  1. 6. Does the psychosocial school environment matter for health? : a study of pupils in Swedish compulsory school from a gender perspective

    Författare :Katja Gillander Gådin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; psychosocial school environment; demand; control; social support; classmate problems; rowdiness; ill health; health behavior; power; gender;

    Sammanfattning : Despite the fast-growing evidence of the importance of the psychosocial work environment for the health of adults there is a lack of research about the possible health effects of the work environment among pupils, that is, their school environment. This is especially true for the psychosocial aspects of the pupils' school situation. LÄS MER

  3. 7. Nonparametric tests for comparing two treatments by using ordinal data

    Författare :Helen Wahlström; Elisabeth Svensson; Jan Lanke; Sture Holm; Örebro universitet; []

    Sammanfattning : This thesis concerns four nonparametric tests for comparing two treatments in a randomized controlled clinical trial when the main response variable generates discrete or continuous ordinal data and measurements are made at baseline and follow-up. In the Wilcoxon-Mann-Whitney test (WMW) the baseline values are not taken into account at all, but in the other three tests both baseline and follow-up values are used. LÄS MER

  5. 9. Centralized Routing for Prolonged Network Lifetime in Wireless Sensor Networks

    Författare :Ewa Hansen; Mats Björkman; Mikael Nolin; Dag Nyström; Thiemo Voigt; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Wireless sensor networks; routing; energy efficiency; asymmetric communicaiton; communication; power consumption; computer networks; trådlösa sensornät; trådlös; kommunikation; energikonsumtion; Computer science; Datavetenskap; Computer Science; datavetenskap;

    Sammanfattning : In this thesis centralized routing methods for wireless sensor networks have been studied. The aim has been to prolong network lifetime by reducing the energy consumed by sensor-node communication.Wireless sensor networks are rapidly becoming common in application areas where information from many sensors is to be collected and acted upon.

  7. 10. Purchasing Power and Purchasing Strategies - Insights From the Humanitarian Sector

    Författare :Ala Pazirandeh; Teknisk logistik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Humanitarian logistics; Purchainsg; Resource dependency theory; Buyer-supplier power;

    Sammanfattning : In this dissertation, we discuss how buyers practice purchasing strategies in an asymmetric power situation favoring suppliers, and how their purchasing strategies practiced impact their purchasing power and buyer-supplier relationships. Organizations enter exchange relationships to access required resources not produced internally, and are exposed to uncertainty from not being able to fully control or predict flow of resources.
