How Digital Communication Initiates Relational Erosion- A Multiple Case Study of Relationships in Three Swedish SMEs
(2021-06-29) Hasselberg, Willy; Karlsson, Oscar; University of Gothenburg/Graduate School; Göteborgs universitet/Graduate School
The study takes interest in digitalization’s influence on people in their business lives and more particularly on how digital communication technologies affect relationships at SMEs. It starts by introducing the topic to the reader describing the phenomenon at large. Since only a fraction of the organizational studies over the years have emphasized technology when trying to explain people’s behaviors, this study aims to fill that gap. Therefore, it investigates the influence of digital communication technologies on the daily work of employees in a qualitative study including three SMEs who use digital communication technologies frequently. The methodological path of interviews is chosen in order to get detailed information from the respondents and to be able to answer how digital communication influences relationships in SMEs. The collected material highlights significant relational downsides with increased use of digital communication while also stressing the perceived increased efficiency and focus as positive outcomes. The analysis elaborates on the data found in the empirical section with the three main disadvantages of an increased use of digital communication: the isolation of individuals, the isolation between teams, and the gradual erosion of relationships. These disadvantages are thereafter put in relation to the benefits of communicating through digital tools which are increased efficiency and greater flexibility for the individuals.
Möjligheter hos framtidens kolliderare

Standardmodellen beskriver mycket av partikelfysiken val, men det finns frågeställningar som kan undersökas hos kolliderare. Syftet med detta arbete ar att undersöka möjligheterna hos föreslagna partikelkolliderare genom litteraturanalys och simuleringar, samt skriva en populärvetenskaplig artikel. De föreslagna kolliderarna som behandlas är Circular Electron Positron Collider (CEPC), Compact LInear Collider (CLIC), International Linear Collider (ILC), Super Proton Proton Collider (SPPC), Future Circular Collider både for leptoner och hadroner (FCC-ee respektive FCC-hh), samt Large Hadron Colliders uppgradering High Luminosity (HL-LHC). Litteraturanalysen sammanfattar några av de områden som kolliderarna kan undersöka, samt ger en översikt av några modeller bortom standardmodellen (BSM). Den första simuleringen behandlar framåt-bakåt-asymmetri för en Z-boson som skapar en toppkvark (t) och en antitoppkvark (￣t). Den andra simuleringen estimerar vilken luminositet som skulle behövas for att hitta nya partiklar i en hadronkolliderare vid en masscentrumsenergi på 100 TeV, som FCC-hh. Resultaten av litteraturanalysen och simuleringarna indikerar att nya kolliderare skulle kunna göra signifikanta upptäckter inom partikelfysik, vilka även kan bidra till ökad förståelse av universum. Dock behovs vidare utvärdering inför val av vilka kolliderare som bör konstrueras i framtiden. Utöver detta uppmanas vidare planering kring konstruktion och drift med ett miljöperspektiv i åtanke. Slutligen producerades en populärvetenskaplig artikel som förhoppningsvis kan bidra till allmänbildning.
The influence of EPS and DPS on share price movements in Nordic tenbaggers

This study investigates the influence of earnings per share (EPS) and dividend per share (DPS) on the share price movements of tenbaggers in the Nordic region. The term tenbagger was first coined by the famous investor Peter Lynch and it refers to shares that have generated a return of over 900 percent. The study focuses on this unique sample of companies in the Nordic region, that have been publicly listed during the last 10 years. According to the previous literature, earnings per share is one of the most significant and relevant variables when it comes to explaining and influencing share price movements, while the views on the relevance of dividends per share are a lot more fragmented. As these two variables are popular in company valuations and have been subject of previous research on share price movements, their influence is of interest to examine in the sample of Nordic tenbaggers. A quantitative method is applied with multiple linear regression models and the results show that earnings per share has had a positive significant influence on the share prices while the dividends per share results were a lot more fragmented, just like in previous research. However, on the basis of the main most comprehensive model, dividends per share was deemed not to have had a significant influence, in line with previous dividends and capital structure irrelevance theories.
