1. 1. Contextualizing the Sensemaking Process - A Study of Disrupted Organizations

   Master-uppsats, Göteborgs universitet/Graduate School

   Författare :Erik Tollin; Rouven Hölzlein; [2023-06-29]
   Nyckelord :Sensemaking; disruption; disrupted; disruptive event; cosmological episodes; contextualization; social narrative;

   Sammanfattning : This study aims to find out how the nature of disruptive events influences the sensemaking of organizational members. The general theory of sensemaking is complemented by the theory of cosmological episodes and its four stages in Weick (1993) which is used as the framework for this study. LÄS MER

3. 2. Cosmological Constraints for a Varying Dark Energy Model

   Kandidat-uppsats, Umeå universitet/Institutionen för fysik

   Författare :Abdullah Alsakka; [2023]
   Nyckelord :Astronomy; Varying Dark Energy; Distances;

   Sammanfattning : This paper uses the Pantheon+ data set that consists of 1701 light curves of 1550 unique type IaSupernova to find constraints on various cosmological models and compare them with a varying darkenergy model proposed by Chevallier, Polarski and Linder in the early 2000s and analyze it deeper.The results show a tipping point from a decelerating universe to an accelerating one at a redshift ofz = 0.

4. 3. Cosmological Horizons and the Unruh Effect

   L3-uppsats, Uppsala universitet/Teoretisk fysik

   Författare :Niklas Engelhardt Önne; [2023]
   Nyckelord :Unruh effect; quantum scalar fields; Bogoliubov transformations; accelerated observers; Minkowski spacetime; cosmological horizons; Rindler observers; special relativity; QFT; Unruh-effekten; skalära kvantfält; Bogoliubov-transformationer; accelererande referenssystem; Minkowski rumtid; kosmologiska horisonter; Rindlerobservatörer; speciell relativitetsteori; QFT;

   Sammanfattning : The black hole information paradox, which states that the evaporation of black holes due to Hawking radiation results in a violation of the conservation of quantum information, is arguably one of the most fundamental problems in all of modern physics. Through the equivalence principle, the essence of the problem can be understood and studied in the context of much simpler flat spacetime (described by the theory of special relativity); in this context the Hawking radiation takes the form of the so-called Unruh effect, a thermal effect in the vacuum of a Minkowski quantum field theory that can be measured by accelerated observers.

5. 4. The cosmological polytope of the complete bipartite graph K_{2,n}

   Master-uppsats, KTH/Matematik (Avd.)

   Författare :Erik Landin; [2023]
   Nyckelord :Polytopes; Cosmological polytopes; Gröbner bases; Graphs; Polytop; Kosmologiska polytop; Gröbner baser; Grafer;

   Sammanfattning : A cosmological polytope of an undirected connected graph is a lattice polytope which when the graph is interpreted as a feynman diagram can be used to calculate the contribution of that feynman diagram to the wavefunction of some cosmological models. This contribution can be calculated using the canonical form of the cosmological polytope, which can be computed by taking the sum of the canonical forms of the facets of a subdivision of the cosmological polytope.

7. 5. Den oändliga informationen : Totalbevarande, tillgänglighet och sökbarhet avseende patientjournaler inom Region Skåne

   Master-uppsats, Lunds universitet/Avdelningen för ABM, digitala kulturer samt förlags- och bokmarknadskunskap

   Författare :Hanna Persson; [2023]
   Nyckelord :Archive; long term preservation; medical records; Scandinavian institutional theory; conceptions of time; social time; temporal depth; deep time; Cultural Sciences;

   Sammanfattning : The background to this master´s thesis is a decision by the regional council in Scania, Region Skåne, to preserve all medical records forever. Through the examination of documents and interviews with people associated with the regional archives, and by using Scandinavian institutional theory and time theory, this study looks into how the decision by the regional council is understood and implemented within the organisation.
