(O)sociala medier? : En jämförande kvalitativ attitydundersökning om människors användning av sociala medier och dess inverkan på deras liv och umgänge

This essay aims to find out what impact social media have on the daily lives of Swedish people in regard to their usage and sociability. In order to find that out we have performed four group interviews with a total of 16 people from two different age categories that were later compared. To analyze the empirical data we?ve used the theories on the Network Societies by Jan Van Dijk as a help of understanding. The results show that social media have become an integrated part in the lives of our informants and that a consdierable amount of time is spent on them everyday. In the younger group Facebook was considered the most useful medium as it makes the planning of events easier and can be used as a way of keeping oneself updated on news as well as on the lives of others.

Allt löser sig, bara vi finns på Facebook. : En kvantitativ studie om hur svenska Facebookanvändare i åldrarna 16-25 interagerar med företag på den sociala nätverkssajten.

Because social media is personal and reaches users directly, it has become an important means of communication for companies trying to reach out to their audience (Nygren & Wadbring, 2013). Especially the possibility of interactivity has been discussed as social media's big advantage. But how much two-way communication is actually possible on social media? This is a quantitative study that focuses on how Swedish Facebook users in the ages of 16-25 interact with companies on the social network. The aim was to contribute with increased information and knowledge about how the users mentioned above interact with the companies as well as how the users perceive the companies communication and presence on Facebook.

Does it matter?

Swedish: Det här kandidatarbetet undersöker om karaktärer med icke-normativ sexualitet finns representerade i digitala spel och hur dessa framställs. Arbetet har även fokus på de reaktioner samhället har visat i samband med att spel som behandlar ämnet icke-normativ sexualitet kommit ut på marknaden. Syftet är att uppmärksamma och ge insikt om icke-normativ sexualitet som ämne och hur diskussionen av detta kan leda till en utveckling inom spelmediet. Informationen som användes för att undersöka ämnet och dess reaktioner finns sammanställt under ett forskningsmomentet, vilket sedan utvecklas till flera noveller. Dessa noveller har sedan användes i en undersökning som genomfördes av 11 stycken deltagare. English: This bachelor thesis investigates if characters with non-normative sexuality are represented in digital games and how these are portrayed.

Nätverk i nätverk : en nätverksansats i den nya ekonomin

Society and technology develop together in interaction processes. Because of the development of information technology, the Industrial society has been left behind in favor of a society where information is the key production factor, i.e. the Information society. In the Information society, social functions and processes are organized in networks. These networks integrate geographically separate markets to parts of a complex global economic system.

Wildlife Detection Network

Traffic accidents where wild animals are involved represents between 60 and 80 percent of all reported accidents, depending on location in Sweden. In a country like Sweden, with a lot of forest, there is always risk of a collision with a wild animal. Imagine if you, as a road user, had the possibility to receive warnings when the risk of an accident according to statistics is extra high.Wildlife Detection Network is a wildlife warning system with an information service, which makes the whole concept unique. When an animal is approaching the road, it is registered by sensors, and warning lights along the road are lit to inform drivers of the potential danger. In conclusion, this is a direct warning to all drivers on the road where the system is placed.When an animal is registered by the sensors, information containing time, date, weather circumstances and coordinates are sent to a database.

Jämförelse av nätverksfilsystemsprotokoll i Windowsmiljö

Detta arbete handlar om nätverksfilsystemsprotokollen SMB/CIFS, SMB2 och NFSv3. Arbetet baseras på artikeln ?A New Network File System is Born: Comparison of SMB2, CIFS, and NFS? som skrivits av Steven M. French på IBM, Samba Team. I den artikeln saknas det prestandatester och därför känns det relevant att göra prestandatester för att få fram vilket protokoll som har högst hastighet med olika filstorlekar i Windowsmiljö.

By doing a qualitative study using focus-group-interviews in three municipalities, we were able to examine the personnel?s experience of cooperation issues and opportunities in BoDa-units.

Konstruktion av current conveyors via makromodellering

A current conveyor is an active building block that can be used to implement most active and passive components. It differs from the operation amplifier in that it uses current instead of voltage. The current conveyor also has significantly higher voltage gain over a broader frequency range. To simplify the construction of analogue circuits and increase the construction efficiency it is desirable to use a top-down methodology. This means that the whole system is partitioned into a hierarchy of subsystems.

Computer Network Attack som olovligt våld : en fråga om association, effekt, aktör och mål

I Estland 2007 utbröt vad som kommit att kallas ?Cyberwar I?, vari ett stort antal centrala myndigheters, tillika finansiella institutioners servrar attackerades av massiva så kallade Computer Network Attacks (CNA), utfört av framförallt ryska aktörer. Estland protesterade högljutt, men frågan huruvida CNA är att beteckna som olovligt är allt annat än klar. Prövningen sker mot den folkrättsliga regimen Jus ad Bellum, och huruvida metoden uppfyller vissa centrala begrepp. Men hur skall denna regim appliceras CNA?De frågeställningar som avses besvaras är: hur kan CNA utgöra våld eller hot om våld i enlighet med FN-stadgans artikel 2(4) samt hur kan CNA utgöra väpnat angrepp i enlighet med FN-stadgans artikel 51? Detta avses göras genom en studie inbegripande flertalet folkrättsliga experters teorier på området CNA och våldsanvändning, samt applicering av desamma på en fallstudie av händelserna i Estland 2007.Sammanfattningsvis konstateras att flertalet variabler har bärighet i hur CNA kan uppfylla artiklarnas centrala begrepp, vari frågan om association, effekt, aktör och mål tydligast faller ut.

Ipad som pedagogiskt verktyg i förskolan : En studie om pedagogers och förskolebarns syn på ipad i verksamheten

I dagens samhälle har många kundföretag problem med datalagringen vilket beror på att behovet av att lagra data började öka kraftigt under 2000-talet och har fortsatt öka sedan dess. När kundföretagen började använda sig av virtualisering så expanderade även datastorleken. I samband med att datastorleken växte ville företagen att data inte skulle lagras lokalt utan att den skulle vara lagrad på en central plats som en serverhall och vara överskådlig.Studien utfördes på tre sätt, först undersöktes vilka datalagringslösningar som fanns och det skedde genom litteraturstudier. Därefter kontaktades företag som använde olika lösningar för datalagring. Nästa steg var att kontakta de leverantörer som kundföretag använde sig av och som levererade lösningarna.Under arbetets gång upptäcktes olika lösningar på problematiken med ett ökat datalagringsbehov.

IT-relaterade hot - professionella IT-tjänstemäns farhågor och möjligheter

The objective of this thesis was firstly to examine the possibilities of creating a universal tool for evaluating IT-security. When all the material was gathered we saw that we had strayed away from our subject and that our focus was on IT-threats and IT-professionals apprehensions and possibilities on the subject. The purpose of this thesis was there after to find and identify threats and counter measures in publications and later discuss these with IT-professionals. We found and identified several threats that the professionals encountered in their work. These threats ranged from techniques used by hackers to threats that can arise when the users on the network are poorly educated.

Tillbaka till framtiden - om svensk filmdistribution i den digitala eran

Why is the e-revolution of the Swedish film distribution lingering? In attempting to answer that question, this qualitative study depicts the distribution market of Swedish film and its actors. Thirteen interviews with representatives of the industry have been conducted in search of an understanding of the current situation. Two important conclusions are made. One is that the strong interdependency between the actors of film distribution is inhibiting the acting space of those who seek change.

Sekundärnät för lågtempererad fjärrvärme

Lower energy use in buildings is a result of increasingly stringent energy requirements across Europe. When conventional district heating technology is used in areas with low energy consumption heatlosses do not fall even though the amount of energy delivered is reduced. This reduces income for thedistrict heating company. To maintain their economic viability the district heating companies? majorchallenge is to implement new solutions that minimize heat loss.
