    Författare :Viktor Andersson; Filip Möcander; [2022]
    Nyckelord :Business models; Business Model Diversification; Business Model Innovation; Business Model Integration; Cannibalization; Synergy;

    Sammanfattning : In parallel with the popularization and widespread diffusion of the internet, interest in the concept of different business models (BM) has increased dramatically, attracting the attention of both scholars and managers alike (Dodgson, Gann and Phillips, 2013). As a result, an increasing number of businesses decide to establish themselves and compete in the digital arena (Lee, 2001); many of which are employing what is called a platform model capitalizing on the ability to operate with several BMs simultaneously (Gu, Kannan and Ma, 2018; Aversa, Haefliger, Hueller and Reza, 2021).

  5. 5. Geochronology of gneisses adjacent to the Mylonite Zone in southwestern Sweden: evidence of a tectonic window?

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :James Davies; [2020]
    Nyckelord :Geochronology; Hallandian orogeny; Mylonite Zone; Sveconorwegian orogeny; U-Pb; Idefjorden terrane; Eastern Segment; B-Bulan; Brobacka; Earth and Environmental Sciences;

    Sammanfattning : The relationship between the Eastern Segment and Idefjorden terrane prior to the Sveconorwegian orogeny has long been debated. Evidence of a common history is minimal and localised; at the same time, the notion that the Sveconorwegian orogeny formed as a result of a collisional event is also disputed. LÄS MER
