Voice over IP (VoIP) is a relatively new technology that enables voice calls over data networks.With VoIP it is possible to lower expenses, and increase functionality and flexibility. FromSwedish Armed Forces point of view, the security issue is of great importance, why the focus inthis report is on the security aspect of the two most common open-source VoIP-protocols H.323and SIP, some of the most common attacks, and counter-measures for those attacks.Because of the level of complexity with a network running H.323 or SIP, and the fact that it hasyet to stand the same level of trial as of traditional telephony, a VoIP-system includes manyknown security-issues, and probably at present many unknown security flaws.The conclusion is that it takes great knowledge and insight about a VoIP-network based onH.323 or SIP to make the network satisfyingly safe as it is today, and is therefore perhaps not asuitable solution for the Swedish Armed Forces today for their more sensitive communications..

This thesis is an investigation of Iranian immigrants and their use of libraries in Sweden. It isbased on a combination of a qualitative and a·quantitative method.Using a qualitative method, I give an outline of the history of lran from ancient times up to the present, as well as the different ethnological groups in Iran and their cultures.

In the year of 2006 I moved to South Africa for a year, a land that has fascinated me because of its history. During the time of my stay I became very surprised how strongly apartheid permeates the community where the white South Africans today are building walls around themselves. Through media we get surrounded with pictures that media creates and to find information regarding what?s happening in the world this is, most often, the primary source. Therefore I believe it?s interesting to explore how two different local newspapers from the county of Kalmar, with two different ideologies, present pictures of the same event, namely the revolt of Soweto in 1976 and how these two newspapers relates to racial policies.

AbstractThe aim of this present study was to investigate whether there is a relationship between birth order and the personality trait narcissism using 181 individuals from Finnveden High School in Värnamo (115 females, 60 males, mean age 17, sd=0,94), in the context of the proposal of Sulloway (1996) that personality is influenced by the specialized nich-es siblings adopt in the quest for access to parental resources. A questionnaire which in-cludes Narcissistic Personality Inventory test, Birth order test and also Rosenberg?s self-esteem test in order to investigate if it might has an impact on narcissistic personality trait, was used. Results showed that there was no significant relationship between birth order and narcissism, however, a significant relationship between narcissism and self-esteem was found. Furthermore, there was a significant relationship between narcissism and the individual?s relationship with the mother.

The purpose of this essay was to see how the child's voice was being heard in the verdicts in trials. I looked into court cases where parents wanted custody of their child/children. The focus of my analysis was on how the verdicts were presented and if the child/children were described in the court cases. The method that I used was qualitative documentanalysis. I chose seven court cases to investigate and analyse.I described theories of Foucault's power to get a different perspective on courtroom cases and the children's voice.

A controversial party?s entry into parliament - a review of Expressen?s depiction of the Sweden Democrats (Sverigedemokraterna)The purpose of this essay was to study how Expressen presents the Sweden Democrats, as well as reasoning about the effects this depiction could have on the citizens? opinion.

This study investigates how the host community of Tenerife perceives the socio-cultural effects of tourism on the island. The method chosen for the study was qualitative interviews which were performed with six respondents, each born in Spain, living permanently in Tenerife and employed within service-related occupations. The interview material was interpreted and handled according to a hermeneutic approach. The results of the study showed that the respondents had an over-all positive perception of tourism. Perceived positive socio-cultural effects were related to cultural and linguistic influences.

The aim of the study was to through empirical studies interpret the relation between three partially investigated house foundations, on an abandoned farm in Langhammars on northern Fårö. This relation focused upon two main questions; the time of use and the spatial distribution of the archaeological finds.Trough comparative analysis two of these houses can establish to have been contemporary, the third one is too roughly examined. A discussion about the hypothec idea of two or three contemporary farms was made with a negative result.In house 1 smaller processing of tools of flint has taken place near the fireplace in the larger room. A concentration of pottery was also visible near the fireplace, likely to be connected to cooking and eating. The smallest room in the northeast part of the house could have functioned as a storeroom and/or held workshop activities.The archaeological finds and the distribution of it, strongly indicates that house 1 mostlikely consisted of a dwelling house and house 2 functioned as a workshop; linked to activities with handicrafts.

Purpose: The aim of the thesis is to identify principles of valuation and to reach a solution for how Statens järnvägar can present their leased railroad vehicles in the future.Methodology: The authors have done a case study through a qualitative approach. Interviews have been done with Statens järnvägar, Näringsdepartementet and Riksrevisionen. Annual reports from Banverket and Luftfartsverket have been studied.Theoretical perspectives: The regulations that rule the authorities are a base for the study.Earlier researches done within the subject are presented in this section.Empirical foundation: The empirical foundation of this study consists of primary- and secondary data. The primary data is collected from the interviews that have been done, whilst the secondary data is composed of annual reports, regulations and various other documents.Conclusions: The authors have come to the conclusion that the method of valuation that Statens järnvägar choose, depends a lot on the vehicles hypothetical future. It is difficult to say that only one of the methods would be the correct one..

In this study I compare the donor portraits on wallpaintings in Scanian churches from the 12th and the 15th century and relate them to medieval society.I find that women were equally capable of owning and donating land during the entire period. The image of the ideal woman changed during the 14th century from a married woman to the unreachable mistress of the chivalrous culture and the holy virgin. Women had a natural place beside their husbands in 12th century donor portraits, while single male donors are more frequent in the 15th century. While 12th century donors were supposed to show their position in society by offering plentiful donations directly to God, donors in the 14th century instead strived to present themselves as humble and pious. The individualisation of late medieval society meant that people had to depend on themselves to achieve salvation..

The relatively poor economy in European dairy farming might be improved from efficient feeding systems and dietary management. Increasing herd sizes and transition to loose housing systems in Sweden, increases the possibilities for other feeding systems than separate feeding that is the traditional feeding system in Sweden. Other possible feeding systems are partial mixed ration (PMR) and total mixed ration (TMR), where the TMR system sometimes is associated with overfeeding and thereby increased environmental impact and high feed cost. Diets providing nutrients above or below animal requirements are considered as unbalanced, which in turn are associated with reductions in health, fertility and milk production. On the other hand, a balanced feed ration improves feed efficiency, nitrogen utilization and profitability.
