  1. 1. The effect of cross-border mergers & acquisitions as a driver of better corporate sustainability practices - A study on the post-acquisition context of selected target firms from Sri Lanka and Sweden

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Buddhini Erosha Jayasinghe; Farjana Rifat; [2023-07-19]
    Nyckelord :Mergers and acquisitions M A ; cross-border; sustainability; corporate sustainability practices; Corporate Social Responsibility CSR ; Environmental-Social-Governance ESG framework; target firm; stakeholder theory; resource-based view; acquirer; Sri Lanka; Sweden;

    Sammanfattning : Companies typically strive to expand their realms. To do so, they rely on a series of organic and non-organic growth options, the latter including Mergers and Acquisitions (M&As). M&As continue to grow in number and frequency across national and regional borders in search of strategic complementarity. LÄS MER

  3. 2. Byggbranschen vs. Vård- och omsorgsbranschen: “Kommer någon vinna jämställdhetsracet?” : En studie om hur jämställdhet presenteras i års- och hållbarhetsrapporter inom en kvinnodominerad och en mansdominerad bransch

    Kandidat-uppsats, Södertörns högskola/Företagsekonomi

    Författare :Emelie Meijer; Anna Rossbrei; [2023]

    Sammanfattning : Bakgrund: Jämställdhet definieras av Jämställdhetsmyndigheten (2022) som att “...kvinnor och män har samma rättigheter, skyldigheter och möjligheter”. LÄS MER

  4. 3. Wideband Dielectric Resonator Antenna Array for Autonomous Vehicles

    Uppsats för yrkesexamina på avancerad nivå, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Andreas Johansson; Luke Müller; [2023]
    Nyckelord :DRA; dielectric resonator antenna; 5G; FR2; 28GHz; NR; antenna; circular polarization; autonomous vehicles;

    Sammanfattning : With the rapid advancement of autonomous vehicles, reliable and efficient wireless communication systems with high data rates have become essential for their safe and efficient operation and further evolution. High data rates are found in the higher frequency bands where conductive antennas lack radiation efficiency. LÄS MER

  5. 4. Sensorless Control of Synchronous Reluctance Machines and Permanent Magnet Synchronous Machines for Pump Applications

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)
