1. Learning Together, Leading Change : Understanding Collective Learning in Social Entrepreneurial Organisations
Sammanfattning : This dissertation aims to generate an understanding of collective learning in social entrepreneurial organisations in Sweden, especially during the COVID-19 pandemic. Employing a collective learning-centred perspective, I want to explore the following key areas: a) the learning conditions and organising processes entailed in becoming a social entrepreneur and creating a social entrepreneurial organisation, b) the importance of collective learning for organisational adaptation and change in tackling exogenous factors such as the COVID-19 pandemic, and c) the role of leadership in creating conditions conducive to collective learning processes in social entrepreneurial organisations during the COVID-19 pandemic.

2. Bark lesions and sensitivity to frost in beech and Norway spruce
Sammanfattning : Strong temperature fluctuations and pathogen attacks can cause bark lesions, visible signs of wounds in the phloem and cambium. Pathogenic insects and fungi are able to invade lesions that have not healed, further increasing the damage. LÄS MER
3. Microstructural Decay in High-Strength Bearing Steels under Rolling Contact Fatigue
Sammanfattning : The work presented in this thesis aims to enhance our understanding of material decay in high-strength steels used for bearing applications. The primary objective is to investigate the microstructural changes in two high-strength steels: 52100 steels, a popular bearing steel, and Hybrid 60, a relatively new bearing steel designed for long fatigue life and use at elevated temperatures.

4. Organometallic complexes with antimalarial properties
Sammanfattning : Malaria is a serious disease that causes around 800 000 deaths per year. Current malaria control efforts are hampered by the widespread resistance to common antimalarial drugs, such as the 4-aminoquinoline derivative called chloroquine. LÄS MER
5. Insect-specific viruses as control measures for West Nile virus infection of animals and humans
Sammanfattning : Myggor tjänar som vektor för många medicinskt viktiga virus och dem associerade virussjukdomarna orsakar en stor hälsobörda över hela världen. Myggburna virus bibehålls i naturen genom en enzootisk cykel, där myggan förvärvar viruset genom ett viremiskt blodmål från ett infekterat ryggradsdjur. LÄS MER
