Dataspel, en naturlig del av folkbibliotek? ? En fallstudie på Helsingborgs stadsbibliotek

This paper aims to investigate how Helsingborg?s city library?s visi-tors feel about computer games being available for lending and in which way computer gamers see Helsingborg?s city library as a resource. This was examined first with a study of 100 of the library?s visitors and then with five interviews with computer gamers and an interview with the librarian responsible for purchasing games.The study showed that most visitors were neutral to having games at the library and of the ones that were not neutral many more were positive than negative. Of the five gamers who were inter-viewed, there were several who had borrowed games in the past.

Peer-to-peer som företagslösning

Problemområde: Idag är användandet av peer-to-peer (P2P) - applikationer såsom KaZaa, ICQ och Seti@home utbrett bland privatpersoner. Användningen inom företag är dock ännu i sin linda. Vi kommer därför i den här uppsatsen utreda om ett eventuellt införande av P2P- teknik i ett företagsnätverk ger några fördelar jämfört med en klassisk Client/Server-lösning. Hypotes: Arbetet bygger på hypotesen: ?En P2P-lösning ger fördelar för företaget jämfört med en Client/Server-lösning? Genomförande: För jämförelsen mellan P2P och Client/Server definierades och jämfördes fem områden: Säkerhet, Användbarhet, Tillgänglighet, Bandbredd samt Utrustningskrav. Slutsats: Inom områdena Användbarhet och Tillgänglighet ger en P2P-lösning klara fördelar, däremot inom områdena Säkerhet och Bandbredd visar Client/Server- lösningen istället klara fördelar. Området Utrustningskrav är oavgjort då det inte finns någon märkbar skillnad på lösningarna. Säkerhetsproblemen är P2P-teknologins akilleshäl och det problem som är mest troligt att stoppa stora investeringar i framtiden om det inte löses. Slutsatsen av vår jämförelse blir sålunda: För ett företag som redan har ett existerande Client/Server-nätverk är det inte någon idé att helt byta system, däremot kan det vara av intresse att introducera en applikation som möjliggör skapandet av så kallade Virtuella Nätverk. För ett helt nytt företag kan skapandet av ett P2P-nätverk vara ett väl så intressant alternativ till Client/Server.

Att göra tillit : Hur tillit skapas i interaktionen mellan människor

The purpose of this essay is to examine the origin of generalized trust. We compare existing theories on trust to determine what approach is more fruitful in explaining the prevalence, or absence, of trust. Our conviction is that trust should be viewed as an interaction, rather than a disposition or a rational choice. The sample is based on the countries of the OECD. In total, five different hypotheses are tested: i) that generalized trust is created by equal distribution of income, ii) that generalized trust is created through monitoring of the state, iii) that generalized trust is created through rule by law; iv) that generalized trust is created when the welfare apparatus is guided by principles of universalism; or iv) that generalized trust is created when the state integrates trust networks.

Datorspel - en lek eller sport? : En studie om hur tre svenska dagstidningar framställer e-sport och datorspel 2000-2013

This essay examines how three big Swedish newspapers depicts e-sports and computer gaming and how the depiction change during 2000-2013. The study will also examine whether e-sports is being portrayed as competitive sport. The purpose is to investigate which attitudes that can be identified towards computer gaming and its culture in major newspapers such as Aftonbladet, Dagens Nyheter and Svenska Dagbladet and how these attitudes eventually changed over time. The sources that will be used in both the quantitative and qualitative analysis are based on web articles, mainly because the paper editions does not provide much, if any, information about computer gaming and e-sports and also because of the convenience of being able to quickly find articles to study. Results indicate that computer gaming is being depicted in a clear negative fashion during 2000-2006, and that the depiction of e-sports is somewhat positive but not as glorifying as for the years 2007-2013. During this period, there is a apparent tendency of e-sports being introduced to readers who are unfamiliar with the gaming culture. As for the attitudes towards computer gaming, the depiction is still somewhat negative, mainly because the debate about computer games and violence was revived because of several acts of violence in shape of school massacres and mass murder.

En studie av inbyggda brandväggar - Microsoft XP och Red Hat Linux

Detta kandidatarbete utreder hur väl två operativsystems inbyggda brandväggar fungerar i symbios med en användares vanligaste tjänsteutnyttjande på Internet, samt att se hur likartade de är i sitt skydd från hot. De två operativsystemen som vi utgick ifrån var Microsoft Windows XP samt Red Hat Linux 8.0. Den hypotes vi arbetat kring lyder enligt följande: De två inbyggda brandväggarna är i stort likartade rörande skydd från hot på Internet och uppfyller användarnas tjänsteutnyttjande. De metoder vi använt, för att svara på vår frågeställning, har delats upp i ett funktionalitetstest och ett säkerhetstest. I funktionalitetstestet provades de vanligaste Internettjänsterna med den inbyggda brandväggen och ifall det uppstod några komplikationer eller ej. De två inbyggda brandväggarna genom gick i säkerhetstestet skannings- och svaghetskontroll via ett flertal verktyg. Genom resultatet kan vi konstatera att de inbyggda brandväggarna klarar av de vanligaste tjänsterna på Internet, men att en skillnad föreligger hos dem vad gäller exponeringen ut mot Internet.

De autistiska barnens dataprogram - hur bör de vara?

The main aim of the study was to seek suggestionson how computer programmes should be. That is, if they are to be considered appropriate föraiding children with autism develop their personality.The general conclusion of this study is that computer programmes, that may be consideredappropriate for the above mentioned purpose, should have certain characteristics of whichpedagogic usefulness and user suitability are of primary importance..

Maktstrukturer i svenskt näringsliv: En social nätverkstudie av delade styrelseledamöter i Sverige 1985 och 2005

This paper examines the interpersonal and intercorporate networks of interlocking boardmembers among Sweden's 50 largest publicly traded companies in 1985 and 2005. We find that both the interpersonal and intercorporate networks of 1985 are considerably more coherent and densely connected than those of 2005. The observed changes in social network structure are compared to changes in company ownership in Swedish publicly traded companies during the same period, and it is found that the observed changes in network density and cohesion can be related to a notable increase in the number of foreign board members. These results imply that the social organization of the Swedish system of corporate governance has changed notably during the period. Social network theory suggests that these changes can explain the greater demand for external regulation, decreased homogeneity of board members and increase in board member compensation observed under the period.

WLAN : Oskyddad och okontrollerad datakommunikation

This master?s thesis investigates the technology and security awareness associated with wireless networks (WLAN). It has been stated by the media and theories that many wireless networks are unprotected. This has sparked an interest to investigate the phenomenon in the Jonkoping region.

Är vi artiga mot virtuella agenter?

The CASA-paradigm, Computers Are Social Actors, was introduced in the book "TheMedia Equation" by Reeves and Nass. One of their experiments concluded that we tend to be polite to computers in the same way as we are to people. In this study I have replicated Reeves and Nass experiment but instead of a text-based interface I have used a virtual agentin order to find out if we are polite to the agents, or still to the computer. Two experimental setups was conducted. The two setups had a common first part that was carried out on onecomputer with one agent.
