The Master thesis deals with the analyzing of the actual metodology of information system (thereinafter IS) implementation and the creation of a new more effective methodology that would prevent the repetition of the indentified deficiency. Despite the diversity of individual customers and their requests concerning the IS implementation and modification, it is necessary to apply the procedural approach during the generation of projects. The implementation methodolgy is thus defined by the description of the particular processes of IS implementation.

In this thesis, we describe the principles of IS-IS routing protocol. We introduce the current state of implementation of this protocol within the simulation framework OMNeT++. We present the implementation of the IS-IS protocol created within the ANSA project. Moreover, we employ its variant called TRILL that is nowadays deployed as replacement of STP in data-center environment. The aim is to enable the modelling of the protocols without the need having to build physical architecture.

Formulation of economic and other advantages and possible disadvantages and problems that can occur in case of implementation of other OpenSource components.

As a result of the increased use of the Internet, there are a number of challenges and opportunities regarding the ability to strengthen or weaken the competitive advantage between organizations. One of the challenges is an increased need to gather and manage large amounts of data (big data) as well as the need to develop processes and strategies for customer relationship management (CRM). This study aimed to investigate how and why big data and business processes for CRM can affect the competitive advantage of B2B companies by offering a theoretical perspective and an analysis of a relevant case in the field. This was studied by applying a qualitative case study where theory and empirical data were gathered through qualitative interviews with respondents who work with CRM and data at the selected B2B company. The results of the study showed that the chosen case involving a B2B company in the technology industry can strengthen its competitive advantage as a result of including CRM in its business processes by applying strategies, value creation, multichannels, IT and data and performance assessment in its customer-related activities and processes. The results also showed that the gathering of data in customer-related processes and activities as well as analyzes of this data is a useful asset as it entails the ability to strongly impact the interaction with customers. An unforeseen discovery made was the fact that the respondents showed a reluctance to describe the circumstance of whether they work with big data, despite the fact that most respondents according to the study definition work with big data in their customer-related processes and activities. This discovery can be the basis for future research in the field of big data and B2B companies. / Som ett resultat av den ökade användningen av internet har ett flertal utmaningar och möjligheter avseende förmågan att stärka respektive försvaga organisationers konkurrenskraft uppstått. Bland annat har ett ökat behov uppstått för insamling och hantering av stora datamängder (big data), samt för att utforma processer och strategier för kundrelationshantering (CRM). Denna studie syftade därför till att undersöka hur och varför big data och verksamhetsprocesser för CRM kan påverka konkurrenskraften hos B2B-företag, genom att erbjuda ett teoretisk perspektiv och en analys av ett relevant fall inom området. Detta studerades genom att tillämpa en kvalitativ strategi i form av fallstudiedesign där dels teori och empiri samlades in genom kvalitativa intervjuer med respondenter som jobbar med CRM och data på det utvalda B2B-företaget. Studiens resultat visade att det valda fallet som avser ett B2B-företag inom teknologibranschen kan förstärka sin konkurrenskraft som ett resultat av att inkludera CRM i dess verksamhetsprocesser genom att tillämpa strategier, värdeskapande, multikanaler, IT och data samt utvärdering i sina kundrelaterade aktiviteter och processer. Resultatet visade även att respondenterna uppfattade insamlingen av data i de kundrelaterade processerna och aktiviteterna samt analyser av denna data som en användbar tillgång då det medför förmågan att starkt påverka interaktionen med kunderna på ett positivt sätt. En oförutsedd upptäckt som gjordes var det faktum att respondenterna visade en avhållsamhet avseende påståendet om huruvida de jobbar med big data, trots att flertalet respondenter enligt studiens definition jobbar med big data i sina kundrelaterade processer och aktiviteter. Denna upptäckt gav upphov till framtida forskning inom området för big data och B2B-företag.

Previous research, which addresses the view of the revocation of citizenship for terrorist-related persons, is seemingly critical. It illustrates a lot of problems that an initiation of this action can cause, but despite this, a social debate is underway in Sweden about introducing this particular opportunity. What is really advocated in the Swedish social debate regarding this? The purpose of the study is, by using an argumentative analysis, to see which recurring themes and arguments are expressed in the Swedish social debate. These are then linked to socialistic, liberalistic and conservative views of citizenship in terms of a discussion. The results of the study shows that a number of themes and arguments are visible in the social debate, where it is argued about everything from IS-supporters being citizens regardless of action, to not having the right to take part in the society at all. The majority of the debaters are in favor of some types of action. The conclusion points to the fact that a conservative approach in the examined social debate is dominant, based on that the arguments mostly advocates some kind of action and responsibility. Given that radicalization is a result of exclusion, the conclusion also sheds lights on that lowering the evidence requirements would probably be the most optimal solution for Sweden when it comes to dealing with returning IS-supporters. / Tidigare forskning, som behandlar synen på återkallande av medborgarskap för personer med anknytning till terrorism, är till synes kritiskt inställd. Forskningen visar en hel del problematik ett införande av detta kan medföra, trots det pågår en samhällsdebatt i Sverige om att möjliggöra det. Syftet med studien är att med hjälp av en argumentationsanalys se vilka återkommande teman och argument som uttrycks i den svenska samhällsdebatten om återvändande IS-anhängare och ett återkallande av deras svenska medborgarskap. Detta återknyts sedan till socialistisk-, liberalistisk- och konservativ medborgarskapssyn i form av diskussion. Resultatet av studien visar att ett antal teman och argument synliggörs i samhällsdebatten, där det argumenteras om allt från att IS-anhängare är medborgare oavsett handling, till att de inte har rätt att ta del av det svenska samhället alls på grund av IS handlingar. Den övervägande delen debattörer är förnågon typ av åtgärd. Slutsatsen pekar mot att ett konservativt synsätt i den undersökta samhällsdebatten är dominerande, baserat på att de argument som framförs mestadels argumenterar för någon form av agerande och ansvarsutkrävande. Utifrån att radikalisering är ett resultat av exkludering är slutsatsen att en sänkning av beviskraven förmodligen skulle vara den mest optimala lösningen för Sverige när det gäller hanteringen av återvändande IS-anhängare istället för att återkalla deras svenska medborgarskap.

A substantial amount of IT projects fail or stay challenged in meeting their targets based on project schedule, budget and system requirements.  Leading global surveys in the last decade barely indicate any improvement in the statistical performance of IT projects in spite of the fact that a lot of effort has been taken in the past to identify and fix those critical factors on which the success and failure of IT projects are generally based on. The poor trend and the underperformance of IT projects still continue. Different researches based on different approaches identify different critical factors but to a very large extent people and processes are blamed. This thesis is under taken to understand the impact of Information Systems (IS) processes and methodologies in the success and failure of IT projects. Major challenges within IS processes, such as their initial identification, implementation and organizational process awareness are identified through qualitative research methods. ‘Identification and selection of IS process and methodologies’ is identified as a major challenge within IT projects and is discussed in detail as, why and what difficulties organizations face in the process of  selecting processes and methodologies on a given IT project. A couple of methodology selection frameworks to overcome these difficulties are presented along side with their critical review and improvement. We come to a conclusion that there is a growing need for more efficient and competent methodology selection frameworks as the ones which exist today are barely complete and efficient and if they do then only to a limited and partial degree.

The following qualitative research explores the adoption of Zero Trust in organisations from an organisational and user acceptance perspective. From an organisational perspective, the research highlights essential aspects such as testing the Zero Trust architecture in a pre-adoption phase, involving top management in the planning phase, communicating in a non-technical language, and making end-users feel a personal connection to IS security. The research highlights the importance of balancing the ease of use with security, evaluating the end-user's technical maturity, and carrying out evaluations from a user acceptance perspective. To gather valuable empirical data, the researcher has conducted semi-structured interviews with highly competent respondents within the field of Zero Trust. Most of the literature available today within Zero Trust focuses on technical aspects, and this research is a unique and vital contribution to the limited available research.

English speakers use the concept of "darkness" in a number of metaphors to portray a wide variety of experiences from evil to fear to ignorance. These metaphorical connections or entailments are so natural that we can see an image of a dark-clad person in a film or book and usually be correct in assuming that they are at best questionably moral and at worst a villain. The Old Testament (OT) also employs dark images and dark imagery to various effects. From Job's description of the underworld in Job 3 to Isaiah 's description of the coming light that will dispel the darkness in Isa 8- 9, to the dark paths the wicked trod in Eccl 2:14, the OT uses a number of metaphors of darkness. For most of these examples, it would be easy to assume that the ancient Hebrew writers of the OT were working with the same concepts of darkness that we do today and thus interpret these passages along the same lines as our own modem English metaphors. But such assumptions can and have led to a number of misunderstandings and conflicting interpretations of passages that employ dark images. These miscommunications are most apparent in passages where God's presence is indicated by darkness like at the Sinai and Temple theophanies (Exod 20:19-20 and 1 Kgs 8:12, respectively) as well as later poetry about God (Ps 97:2). By combining the theoretical framework of Cognitive Metaphor Theory (CMT), and the methodology of Conceptual Blending (CB), this study will work toward a clearer understanding of how the writers of the OT understood darkness and how that shaped their use of it in their images and imagery of death, captivity, the unknowable, and God. It will be shown that the ancient Hebrew conception and use of darkness centres around three key recurring metaphors - Death is Darkness, Captivity is Darkness, and the Unknown is Darkness - while the metaphor Evil is Darkness is foreign to the OT. These findings serve to provide greater clarity in interpreting those OT passages that portray God as having a penchant for darkness.
