Detta är en kvalitativ intervjustudie med en abduktiv ansats. Studien undersöker hur två geografiskt närliggande kommuner, Gävle och Uppsala kommun, agerar innan, under och efter en kris när det gäller kriskommunikation och hur respektive kommun förhåller sig till upprättade kommunikationsnätverk. Datamaterialet har främst analyserats enligt Ahuja, Sodaoch Zaheers (2012) fem dimensioner i ett nätverk och Garnett och Kouzmins (2007) fyra linser inom kriskommunikation. I studien identifierades både strukturella skillnader och likheter mellan kommunerna. Uppsala kommun har till exempel två arbetsroller: kommunikatör i beredskap och tjänsteman i beredskap, vilket Gävle kommun inte har. Där utöver ändrar båda kommunerna sin rapporteringsstruktur från en linjeorganisation till en matrisorganisation under en kris. Båda exemplen visar på vikten av det relativa avståndet i kommunerna, det vill säga avståndet mellan anställda/aktörer i kommunerna. Om det relativa medelavståndet mellan aktörerna i kommunerna minskas kan felinformation och problem lättare hanteras. Möjliga aspekter för framtida studier som har identifierats i studien är valet av att ha kraftigt decentraliserade grupperingar i nätverken samt det begränsade antalet plattformar som kommunerna använder under en kris.

This case study researches why the Swedish region Västra Götaland fails to implement the environmental aim to achieve only natural acidification. The study is based on implementation theory and is operationalized by interviews with authorities and text analysis. In conclusion this study finds that the natural condition of the environment in Västra Götalands län has a large impact on the result of implementing environmental objectives. The failed implementation in Västra Götaland is set in relation to another region – Stockholms län – in Sweden, which has succeeded with the same implementation process. In this case study the implementation process was more dependent on the natural conditions of the environment than the function of directed governmental instruments. The study shows that although the implementation process is conducted in the right manner there are still unforeseen obstacles on the way, which is characteristic for implementation processes. Furthermore the study emphasizes the importance of international cooperation with the purpose of counteract the source of the problem rather than just treating the symptom.

Denna studie avhandlar diffusion från externa aktörer och dess inverkan på Vitrysslands utveckling. Landets viktiga geopolitiska läge har gjort att trycket både från väst och öst ända sedan självständigheten har varit stort. För att specifikt granska dessa processer har en avgränsning till EU och Ryssland skett vad gäller externa faktorer. Vi granskar vad dessa två aktörers intressen i Vitryssland bottnar i och hur de försöker påverka utvecklingen. Vitryssland har överlag, sedan Lukasjenkas maktövertagande, rört sig bort från västvärlden och därmed bort från en utsikt till demokratisk utveckling och istället mot närmre integration med Ryssland. Studien presenterar viktiga händelser och faktorer som har lett fram till den nuvarande situationen – varför EU har misslyckats i sina försök till diffusion medan integrationen med Ryssland förblivit stark.

Service oriented computing and web service technology provide the means to structure an organisation’s internal IT resources into a highly integrated network of services. In e-business and business process integration the internal services are interconnected with other, external organisations’ resources to form virtual organisations. This move from using services internally to external use puts new non-functional requirements on the service implementation. Without any supporting technologies, meeting these new requirements can result in re-writing or changing a large part of the service implementation. In this paper we argue that aspect oriented programming is an important technique that can be used to facilitate the implementation of the new requirements that arises when moving from internal to external services. The suggested solution is illustrated by an example where quality of service metrics is implemented by using aspect oriented programming., QC 20101129

The introduction of agile methodologies promises faster time to market anda flexible, customer-driven software development process. The flexibilitywith regards to requirements can however also be a risk if newnon-functional requirements need to be implemented late in a softwaredevelopment project. In this article we argue that aspect-orientedprogramming is a technique that can mitigate this risk by providing themeans to deal with non-functional, crosscutting requirements. The suggestedsolution is illustrated by an example where new requirements in the form ofquality of service demands on an existing service are implemented by usingaspect orientated programming., Workshop on Software-engineering Properties of Languages andAspect Technologies, Fourth International Conference on Aspect-OrientedSoftware Development (AOSD 2005), 2005, Chicago, Illinois, USA, March14­18

Encryption is an important method for implementing confidentiality in information systems. Unfortunately applying encryption effectively can be quite complicated. Encryption, as well as other security concerns, is also often spread out in an application making implementation difficult. This crosscutting nature of encryption makes it a potentially ideal candidate for implementation using AOP. In this article we provide an example of how database encryption was applied using AOP with AspectJ on a real-life healthcare database application. Although the attempt was promising with regards to modularity, amount of effort and security engineering, it also revealed problems related to substring queries that need to be solved to make the approach really useful., QC 20101130.

Agile methods, such as eXtreme Programming (XP), have been criticised for being inadequate for the development of secure software. In this paper, we analyse XP from a security engineering standpoint, to assess to what extent the method can be used for development of security critical software. This is done by analysing XP in the light of two security engineering standards; the Systems Security Engineering-Capability Maturity Model (SSE-CMM) and the Common Criteria (CC). The result is that XP is more aligned with security engineering than one might think at first. However, XP also needs to be tailored to better support and to more explicitly deal with security engineering issues. Tailoring XP for secure software development, without removing the agility that is the trademark of agile methods, may be a solution that would make XP more compatible with current security engineering practices., QC 20101109
