Klassifikationssystem på webben: Traditionella och nya
The aim of this thesis is to investigate the opportunities of classification of web pages. Two classification systems are compared; a library classification system traditional and a system that is developed for use on the web new. UDC is chosen to represent the traditional systems, and Yahoo! represents a so called new system. UDC is used by NISS Directory of networked resources, which is a directory that uses the system for organisation of electronic resources. Both systems are analysed from two different perspectives, a multidisciplinary and a timeperspective.
En union, ett samarbete och en valuta i kris : En kvantitativ studie om Spaniens och Sveriges mediala framställning av euro- krisen inom EU
AbstractTitle: A union, a collaboration and a currency crisis- a quantitative study of the media coverage of the euro crisis within the European Union in Spanish and Swedish newspapers.The purpose of this study was to see whether Sweden and Spain ?s differences in media climates and relations to the euro crisis would affect how the story was portrayed from a narrative perspective. Did the coverage differ between the two countries and who got to comment on the situation in the media were two of the questions I strived to answer. I also wanted to see how the coverage reflected on the situation that the euro crisis has created.In this study I used a number of theories that I based my research on. The main theories I focused on was about different media systems and Sweden and Spain ?s relation to the euro crisis.
Installation av övervakningssytem ombord på fartyget M/S Andromeda
This report is regarding an electrical installation of an alarm system on a post fishingboat called Andromeda. The background of the installation was an earlier andinadequate alarm system that led to a motor failure. The ship was taken out of serviceand was sold to Björn Magndahl who rebuilt it to a yacht.The project was conducted partly by developing the existing systems, partly bydocumenting the work by means of electrical blue prints. Except the alarm systems, aninstallation of the frequency control unit for the bow thruster was installed.The installation was working fine and the outcome of the documentation was handedover in a form of a binder during the test drive of the systems and the assignment wasapproved..
Valutamarknadens effektivitet - En studie av växelkurser utifrån UIP med förväntningar
This essay discusses and evaluates the international currency market in regards to efficiency. To prove the theory that, the difference between expected and actual exchange rates is explained by the difference in expected and actual interest rates and the difference in expected and actual inflation between countries, a model was developed. This model was inspired by the paper of Sebastian Edwards (1982), and is based on three theories; UIP, IS/LM and the Efficient Markets Hypothesis. The model uses 16 regressions estimated from three pairs of curriencies: $/SEK, £/SEK and ?/SEK.
XML som informationsbärare för EDI
Information handling has been a key issue for different companies for a long
time. Electronic Data Interchange (EDI) is used to transfer different business
documents from one company to another. This is done in such way that the
information itself is separated from how this information is stored and handled
in the companies internal systems. As different companies have different
systems there is a need for a standardised format for this exchange.
There is a big difference between EDI-systems based on what kind of
EDI-standard is used. The most common standard in Europe is EDIFACT, but with
increased interest of using the Internet for business communication there is a
need for a standard that is adjusted for use over the Internet.
Specialpedagogers arbete i fo?rskolan med fokus pa? inkludering. Special educators work in preschool with focus on inclusion.
How do special educators work to include children with special needs in preschool? That was the question that our thesis proceeded from, and the purpose was to get an insight in the methods used by the special educators to achieve inclusion.
Our questions were:
? Is Swedish preschool a place for inclusion?
? How are special educators work organized and focused?
? Which experiences do special educators have working with children with special
needs in preschool, and what role do they mean that inclusion plays in this work?
Our procedure in this enquiry was to perform semi-structured interviews with 5 different special educators in two different cities.
Interpretation and analyis proceeded from three different theories: Urie Bronfenbrenner?s ecological Systems theory, John Bowlby?s theory of attachment and Karsten Hundeide?s sociocultural theory. The result showed support for the idea of the Swedish preeschool as a place with many opportunities for inclusion. We have also seen how both money and political decisions has an impact on which possibilities the preschools receive to work with inclusion. In addition it became apparent that the methods used by special educators differed depending on both cities and districts.

Systemarkitektur för presentation av geografiskinformation- Utredning av Informationssystem och produkter
Banverket Trafik has a responsibility to make sure that the companies who traffic the Swedish railroad have the correct information about the status of the railroad. One of Banverket Trafiks information systems (Opera) presents the train?s actual position on a map and provides the user with physical information about the trains. Due to increasing demands on the information systems, Banverket Trafik needs to update the present system architecture in order to manage the increasing demands on map graphics and map functions. This paper analysis the information system Opera on the basis of theory and support of methods and discuss problems and demands for Opera.
Vatten- och avloppssystem i klimatförändringarnas tidevarv : - en studie om VA-situationen i Karlstads kommun, dess sårbarheter och anpassningsförmåga
This report is about the impact climate change has on the water and sewage systems in general, and the situation in the municipality of Karlstad in particular. Which vulnerabilities are linked to water and sewage systems with regard to climate change and extreme weather situations, what are the possibilities to adapt the system to this and what significance does climate adaptation of the water and sewage systems have in relation to sustainable development?To answer these questions I have studied literature on the subject and interviewed several people who work with these types of questions. The answers I have received state that there are a multitude of vulnerabilities linked to the water- and sewage systems, but that there are also many strong interests which strive to take measures and adapt to a changed climate. I have also come to the conclusion that the starting points and views of the possibilities to act differs between the people that I have interviewed, but that theses problems are built into the concept of democracy..

Lyssna! : Sex vuxna individers upplevelser av att berätta om de sexuella övergrepp de har utsatts för i sin barndom.
The aim of this qualitative study was to examine six individuals' experiences to talk about the sexual abuse that occurred in their childhood. We interviewed five women and one man, using a phenomenological approach during the work process. The theories emerged as we analyzed our results and appeared to be communication, cognitive theory, validation, trauma theory and taboo. The results showed that the respondents, whom disclosed the abuse as children, were most likely to get a negative response from both formal and informal support systems. While as adults they were confirmed to a greater extent and therefore achieved a better physical and mental wellbeing.
Tidsstudie - grovfoderhantering :
Since feeding fodder crops to dairy cows is a heavy and time-consuming but often
disregarded line of work, this study wishes to view the different possibilities that are
currently available to decrease the time to feed and apply this knowledge on an
existing farm. For this purpose, four farms have been studied due to what feeding
systems that are currently used and how long time the feeding required. The occurring
systems are either mobile, i.e. a feed mixer operated by a tractor witch feeds the cattle
via a drivable fodder table, or a stationery mixer, i.e. an electrically powered mixer
which fills an automatic feeder.
Hur hanterar institutioner en miljö med blandade Operativsystem?
The purpose of this thesis is to investigate if there are environments that use some kind of central authentication system within institutions/schools. The hypothesis is that an institution not using a form of central authentication service has more need for maintenance and as such is considered a higher cost for the organization. The gathering of data has been done through interviews with technical personal at Blekinge Tekniska Högskola and Linköpings Universitet. Based on the technical background of the authors, and the system limited to discussing Windows and UNIX operating systems, a discussion and analysis of the systems working today has been done, with emphasize on the hypothesis..
Museum på webben - en undersökning om användbarhet och åtkomst
The aim of this thesis is to describe and evaluate the usability of two Swedish systems, Sofie and Carlotta, which are used to organize and present data regarding museum objects on the web. This thesis also presents how objects are described and made accessible to the public in the two systems. To evaluate the usability, a heuristic method combined with Systematic Usability Evaluation has been used. The description and accessibility of object representations in the systems are evaluated using indexing and classification theories from the field of Library and Information Science. Additional theoretical background that has been used is how users search and browse information systems.
