<p>Avregleringen av finansmarknaden 1992 möjligtgjorde för andra finansiella aktörer än bankerna att etablerar sig på den svenska marknaden. Stora banker gick samman med andra finansiella institut och bildade konglomerat, som inte sällan sträcker sig över landets gränser. Små banker inriktade mot specifika verksamheter ökade också sina kundunderlag och har börjat ta marknadsandelar i sina segment från storbankerna. Studien går ut på att se om det finns någon tendens till att nischbankerna skulle vara på väg att konkurrera ut storbankerna. I uppsatsen studerar jag utvecklingens bakomliggande drivkrafter. I den empiriska delen studeras bankernas utveckling på in- och utlåningsmarknaden. Resultatet av jämförelsen mellan storbankernas och nischbankernas in- och utlåning visar att nischbankerna har ökat sina marknadsandelar inom de segment de är verksamma i, medan storbankerna sin totala omslutning. Och slutsatsen är att nischbankerna knappast utgör något allvarligt hot mot storbankerna.</p>

The aim of the first part of this thesis was to investigate (R,R)-PBI as a model system for polymorphism at its origin by a supramolecular approach. The pathway complexity of (R,R)-PBI was fine-tuned by experimental parameters such as solvent, temperature and concentration to make several supramolecular polymorphs accessible. Mechanistic and quantum chemical studies on the kinetics and thermodynamics of the supramolecular polymerization of (R,R)-PBI were conducted to shed light on the initial stages of polymorphism. The second part of this work deals with mechanistic investigations on the supramolecular polymerization of the racemic mixture of (R,R)- and (S,S)-PBI with regard to homochiral and heterochiral aggregation leading to conglomerates and a racemic supramolecular polymer, respectively. / Das Ziel des ersten Teils der Dissertation war es, anhand des Modellsystems (R,R)-PBI Polymorphismus mit Hilfe eines supramolekularen Ansatzes an dessen Ursprung zu untersuchen. Durch die Wahl geeigneter experimenteller Parameter wie Lösungsmittel, Temperatur und Konzentration wurden die komplexen Polymerisationspfade von (R,R)-PBI gezielt beeinflusst und verschiedene supramolekulare Polymorphe zugänglich gemacht. Mechanistische und quantenchemische Untersuchungen der Kinetik und Thermodynamik der supramolekularen Polymerisation von (R,R)-PBI wurden durchgeführt, um die Anfangsphase des Polymorphismus zu beleuchten. Der zweite Teil der vorliegenden Arbeit befasst sich mit mechanistischen Untersuchungen der supramolekularen Polymerisation der racemischen Mischung aus (R,R)- und (S,S)-PBI im Hinblick auf homo- und heterochirale Aggregation, welche zu Konglomeraten beziehungsweise einem racemischen supramolekularen Polymer führte.

<p><strong>Purpose: </strong>The essay was designed to examine what impact an increased media concentration in the provincial press may have on the society in the future.

Purpose: The essay was designed to examine what impact an increased media concentration in the provincial press may have on the society in the future. I also had the intention to create a greater understanding of the concept of media concentration and how the media groups relate to the public interest.   Method: The work with this study was conducted by using methods from the qualitative methodological arsenal through interviews with, for the study, relevant informants, but also through a case report on the Stampen Group. The selection of informants had a background and a breadth which secured the credibility in this survey. The starting point was taken in previous research via a deductive approach where I tested how existing theories match reality.   Conclusion: After completing this study should be noted that all respondents believe we will see a greater concentration of ownership in the Swedish media market in the future, and that it will reduce diversity. However, there are steps to take which I believe can work well in theory but perhaps not always in practice.
