  1. 31. Constraints and symmetries in theories of interacting spin-2 fields

    Författare :Anders Lundkvist; Fawad Hassan; Edvard Mörtsell; Antonio Padilla; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; modified gravity; bimetric theory; spin-2 fields; classical field theory; partially massless symmetry; teoretisk fysik; Theoretical Physics;

    Sammanfattning : The Hassan-Rosen bimetric theory describes two interacting spin-2 fields, one massless and one massive. In this thesis, a complete canonical analysis of this theory is performed in the metric formulation and all constraints are computed. LÄS MER

  3. 32. Elastic and inelastic scattering effects in conductance measurements at the nanoscale : A theoretical treatise

    Författare :Peter Berggren; Jonas Fransson; Wolfgang Belzig; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Scattering theory; Scanning tunneling microscopy; tunnel junctions; molecular graphene; paramagnetic molecules; spin interaction; nano electromechanical system; Josephson junction; superconductivity; chaos; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : Elastic and inelastic interactions are studied in tunnel junctions of a superconducting nanoelectromechanical setup and in response to resent experimental superconducting scanning tunneling microscope findings on a paramagnetic molecule. In addition, the electron density of molecular graphene is modeled by a scattering theory approach in very good agreement with experiment. LÄS MER

  4. 33. Den potentiella människan : En undersökning av teorier om självförverkligande

    Författare :Staffan Nilsson; Carl-Henric Grenholm; Mikael Lindfelt; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Ethics; Self; self-realization; self-fulfilment; self-actualization; human development; internalism; relationalism; reconciliation; Abraham H Maslow; Charles Taylor; Alan Gewirth; Reinhold Niebuhr; Bernard Lonergan; Etik; Philosophy subjects; Filosofiämnen;

    Sammanfattning : “What characterizes an acceptable theory of self-realization?” The thrust of the present dissertation is towards seeking an answer to this central problem, which stems from the fundamental human experience that life involves change, and that in a modern society such change is often expected to be towards a realization of potentials and the good life for the individual. The dissertation has a three-fold purpose. LÄS MER

  5. 34. Production in a State of Abundance : Valuation and Practice in the Swedish Meat Supply Chain

    Författare :Jonas Bååth; Patrik Aspers; Tora Holmberg; Turo-Kimmo Lehtonen; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; abundance; production; valuation; Swedish meat industry; supply chain; post-scarcity society; economic sociology; food studies; agriculture; grocery retail; pragmatism; practice theory; ethnography; Sociologi; Sociology;

    Sammanfattning : This thesis is a sociological contribution to the study of abundance. It discusses the case of Swedish meat producers and how they persist in producing pork and beef despite a lack of demand and competitive disadvantages compared with foreign suppliers. LÄS MER

  7. 35. The Development of Swedish Business Journalism : Historical Roots of an Organisational Field

    Författare :Maria Grafström; Kerstin Sahlin-Andersson; Lars Engwall; Stefan Jonsson; Royston Greenwood; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business studies; institutional theory; organisational field; field emergence; institutional entrepreneurs; business journalism; business news; newspapers; Företagsekonomi;

    Sammanfattning : Contemporary Swedish business journalism is an established organisational field with shared practice within and across organisations. Using a historical perspective, this dissertation investigates the early formation of this field and the formation of a shared meaning system for business journalism. LÄS MER
