IDS för alla : Intrångsdetekteringssystem för hemmaanvändare
I dagens IT-samhälle är säkerhet en viktig aspekt. Ett sätt att nå högre säkerhet är att bygga upp säkerheten i lager. I hemmanätverk är två vanliga lager antivirus och brandvägg.Den här kandidatuppsatsen undersöker om ett intrångsdetekteringsystem (IDS) är ett bra komplement till säkerheten i ett hemmanätverk.För att hålla systemet så attraktivt som möjligt för hemmanätverket fokuserar man på att hålla priset nere och konfigurationen enkel. Vi valde enkorts-datorn (Raspberry Pi) med programvaran IPFire, som är open-source, där IDS:en Snort ingår och IPFire har ett enkelt gränssnitt för konfiguration.För att mäta hur effektivt systemet fungerar, mäts det hur många hot Snort upptäcker. Mätningar gjordes också för att undersöka om systemet orsakade prestandaförluster i hemmanätverket.Av resultaten drogs slutsatsen att systemet är ett bra komplement till säkerheten i ett hemmanätverk.
Historiebruk : exemplet Judisk Krönika
The purpose of this examination is to investigate how Judisk Krönika, a periodical which was introduced in 1932 with the aim of disseminating Jewish culture and tradition in Sweden, uses history to make comments about its role in contemporary history, specifically during the first two years of the First Intifada. A second purpose was to examine how this use of history differed from results shown in earlier studies comprising the 1960s and the 2000s. The method in use is qualitative; the source material has been read thoroughly and scrutinized in search of the authors open and hidden messages and intentions. The main finding shows that four major themes could be identified: anti-Semitism(anti-Zionism); memory; ethnonational and media. The most dominant theme during the 1980s, as opposed to the 1960s and the 2000s focus on Zionism and Jewish culture respectively, is memory, that could be described as hegemonic and as a part of a existential use of history, which aims for survival and preservation of the Jewish culture in times of conflict..
Den som hoppar högst är bäst? : En kvalitativ intervju-studie om gymnasieelevers uppfattningar om betyg och bedömning i idrott och hälsa
abstract buzz marketing, the phenomena Have you ever thought about why the small French pastries called macarons suddenly became so extremely popular? Soon they were seen everywhere in the media, on every celebrity party and shortly after of course on every Swedish person?s cake dish. Could it be that a trendy it-girl happened to mention these lovely creations in her blog?What (or who) is it really that decides and controls what is popular and what is going to sell? If one individual can influence a whole group of followers it is definitely something marketers should take advantage of. One cannot any longer rely on traditional advertising, one needs to be more creative and rethink the possibilities to get through the media noise.
Elevers syn på klimatfrågan : Klimatundervsiningen i skolan
The aim of this study is to find out in which way the education about climate in school is taught and how the students experience the world situation today. There are various theories about the greenhouse effect and its origin and these theories should be addressed to ensure that students get a broader understanding of how climate change occurs. This includes the natural phenomena and also the human impact on climate change. Students in school are a source of concern that only human are the cause of global warming, and know little or almost nothing about the natural phenomena of global warming. I will mention what has emphasized in the national steering documents in the case of environmental education at school.I have used a qualitative method, where interviews and document analysis were used as techniques. The interviews took place with five students in ninth grade and with three science teachers in the same school..
Kunskap i skolan : enligt Folkpartiet och Vänsterpartiet
Knowledge is frequently discussed in modern society, and has been since ancient Greece. Our goal is to examine the content of two political documents with the desire to point out their visions about how the Swedish school system should be shaped, in relations to knowledge. More precise this essay is going to concentrate on two specific political parties, Folkpartiet and Vansterpartiet and their official programs on the subject school and education, to see what they say about knowledge. The choice is made on the basis that these parties political standings differ most from each other, in the left/right scale in politics. The qualitative analysis takes its main base from Aristotels concepts of knowledge; Episteme, techne and fronesis, and Bernt Gustavssons modern defenitions of them.

Ekologiska fotavtryck för koldioxidutsläpp för Stockholms län, Norrbottens län och Stockholms läns landsting : En kritisk metodgranskning baserad på kvantitativa data
Human existence and welfare depend on functional ecosystems. Ecosystems are critical to sustain life-support services for human well-being. One method that visualizes that humanity requires ecosystem services for resource consumption and assimilation of produced waste is ecological footprints. This study focuses on the ecosystem service carbon sequestering. A quantification of this ecosystem service showed the potential for accumulation of carbon in different ecosystems in Stockholm and Norrbotten County for the years of 1995 and 2004.
EN MILJ?STUDIE OM DE GEOKEMISKA F?RH?LLANDENA I SK?RHAMN, SVENSKA V?STKUSTEN
The following study aims to investigate the environmental conditions of the harbor of Sk?rhamn, a small fishing community on the west coast of Sweden. The interest to do so rose as a newly built apartment residence failed to connect the sewage pipes of 18 apartments, causing the untreated sewage running into the sea. The parameters accounted for are the C/N ratio, total organic carbon (TOC) as well as total nitrogen present (TN) and ?13C in the top ten centimeters of a sediment core retrieved in the Sk?rhamn harbour.
"I en optimal värld skulle det inte se ut som det gör idag" : En kvalitativ fallstudie om vad som ha?nder na?r kravdokumentation inte tas pa? allvar
Requirements engineering is a widespread topic in the research field of informatics. However, there is little research regarding lack of requirements documentation and how it is perceived. The same applies for how requirements engineering in retrospect can be implemented. This is a debated issue on blogs and forums but it has not been reflected in the research area.Therefore, this study concerns research questions regarding how the developers, testers and requirements analyst experience the lack of requirements documentation and how requirements engineering in retrospect can be implemented.To answer these questions, data collection has been conducted through qualitative interviews with individuals affected by this problem in their everyday work.This study has provided an explanation of how the problem is perceived and what the consequences are, both direct and indirect. The impacts are divided into three categories and are presented as, emotional consequences, system implications and consequences regarding re source consumption.
Filosofen som arkitekt : Subjektivitet och metaforik i Discours de la méthode
In this paper, I have proposed a way of interpreting the philosophical subject of the Discours de la méthode that has remained relatively unexplored by contemporary commentators. By investigating the subjectivity that is expressed through Descartes? use of architectural metaphors, I laid bare some of the difficulties inherent in its discursive structure, as well as suggesting that the cogito in fact repeats and inscribes itself into this structure. In this context, the metaphor of the road (or travel) takes a supplementary role in relation to the architectural metaphor, marking the very conditions of existence of the architectonic subject. The subject, in order that it may establish itself as ?pure? and ?independent? thought, is dependent on a certain ?forgetfullness?; that is, only by forgetting its constitutive dependence on the diversity and historicity that is signified by the metaphor of travel, can it establish itself as its own source.
Sponsring som finansieringsmetod : Kulturens nya villkor

Att söka samhällsinformation. En användarundersökning
Citizenship information is defined as the information the citizen needs to be able to take part in and influence the society. Since it is a democratic issue that information concerning the citizens role in society really reaches the citizens, it is of importance to study how the citizens proceed when they have a need for this information. The aim of this Masters thesis is to investigate how our eight informers proceed when they experience this need in a non-work situation. We performed qualitative interviews. The most important part of our interviews was the introduction of some fictitious problems to the informants.
Sjuksköterskans attityd till att vårda patienter med psykisk sjukdom i den somatiska vården
De psykiskt sjuka tar allt större plats inom den somatiska sjukvården men forskningsfältet är nytt och kunskapsluckor existerar. En systematisk litteraturstudie gjordes. Litteraturstudiens syfte var att belysa sjuksköterskans attityd till att vårda patienter med psykisk sjukdom i den somatiska vården.En databassökning har gjorts i fyra databaser med omvårdnadsfokus: Cinahl, Pubmed och PsycInfo. Sex studier inkluderades. Ur dessa har utkristalliserats tre återkommande teman: attityder som avspeglar sjuksköterskans erfarenheter, vårdmiljöns betydelse på sjuksköterskans attityder och utbildningens betydelse för sjuksköterskans attityder.En stor mängd negativa attityder existerar men även en del positiva, ofta knutet till sjuksköterskan personliga attityder.
