    Jag ångrar inte att jag blev lärare En global analys av lärares utvärdering av deras arbetssituation och yrkesval

    This paper examines how teachers over the world evaluate their work situation and their choice of profession with a quantitative method. The paper uses data from the teacher questionnaire from the 2022 PISA survey, and the questions within that asks the respondent if they regret choosing to be a teacher and if they are generally happy with their work life. This data is examined from factors both on systemic and individual level. The paper’s theory says that some factors should affect the satisfaction positively. On systemic level Education index, democracy and economy are mentioned, where on individual level gender, age and education is used. There is also one factor on each level that is impossible to operationalize, the grade of New public management in the country, and if the teacher has a parent that works/has worked in pedagogy. The result is that most teachers tend to answer considerably more positively on most of the questions, ergo they are satisfied and not regretful. The Dominican Republic stands out as having answered the most positively, and Portugal the most negatively. Regarding the systemic factors, they all affect the satisfaction negatively, contrary to theory. Age tends to affect satisfaction positively, and so does teachers’ education. Gender pertaining regret affects negatively, where men tend to regret their work choice more.

    Patterns in Interacting Quantum Gases
    (2021-11-19) Bekassy, Viktor; Heuts, Olivia; Lech, Alex; Lundqvist, Carin; Magnusson, Erik; University of Gothenburg/Department of physics; Göteborgs universitet/Institutionen för fysik
    Quantum gases is a novel field of experimental research, where it is possible to study the universal behaviour of quantum particles under controlled circumstances. In two experiments by Zürn et al. and Holten et al., patterns such as paring effects, magic numbers and Pauli crystals have emerged in a quantum gas consisting of a few ultracold 6Li atoms confined in an optical trap. By modelling these experiments and using the universal behaviour of quantum particles, we can achieve a greater understanding of how the building blocks of our universe behave and then apply that knowledge to more complicated systems, such as neutron stars or the atomic nucleus. This thesis aims to model the mentioned experiments as a few interacting fermions in a harmonic potential. By treating the interaction as a minor perturbation and calculating the energy of the system numerically with perturbation theory, we were able to compare our results with the experiments by Zürn et al. and found that they were in good agreement. Both showed a pronounced shell structure, resulting in magic numbers, and the emergence of pairing between fermions. Furthermore, the results were consistent with our analytically derived solution for two particles. Additionally, Pauli crystals in one and two dimensions were simulated using Matlab and the Metropolis algorithm, resulting in us successfully recreating the very recent experimental results by Holten et al.. Finally, interactions were added to Pauli crystals in 1D, showing new pairing patterns and opening up for further research.

    VS-satser och subjektsutelämning i svenskan
    (2003-11) Magnusson, Erik
    I likhet med övriga germanska språk, engelskan undantagen, brukar svenskan räknas till V2-språken. Med detta avses att det finita verbet kommer på andra plats i påståendesatsens inledning. Emellertid förekommer det att denna princip frångås. I vissa fall står verbet först i påståendesatsen. Sådana satser brukar kallas V1-satser och finns såväl i modern svenska som i 1600-talssvenska, vilket visas i (1). (1 a) De va en, nja en fullgubbe ba, ungarna hade ba, ungarna hade ba cykla runtan, kom hans brorsa å lappa tilan. (Kotsinas 1994:73) (1 b) Uthi sielfwe Staden boor een Visier Bassa, hwilken håller sig mächta prächtig. Och kan man inthet gierna allena gå säcker in uthi Staden [...] (Kiöping 1667) I 1600-talssvenska, men inte i modern svenska, är det tillåtet att utelämna ett subjekt från platsen efter det finita verbet. Detta visas i (2). (2 a) Twenne af thesse Munckar fölgde oss till Wägs och under Wägen wiste (de) oss många namnkunniga Platser […] (Kiöping 1667) (2 b) Nilsson åt upp köttbullarna och sedan stoppade *(han) in en pris snus. Som Mörnsjö (2002) illustrerar tycks det finnas goda skäl att misstänka att moderna V1-satser inleds av ett dolt adverbiellt element; de skulle med andra ord kunna betraktas som dolda V2-satser. Ingenting verkar tyda på att de äldre V1-satserna är av det slaget. I detta föredrag argumenterar jag för att det är mot bakgrund av denna strukturella skillnad som skillnaden i (2) bör förklaras.
