Vi kallar personlighetstypen för kreativa dagdrömmare : En kvalitativ studie av professionellas erfarenheter och åsikter kring ungas dataspelsproblematik
Dataspelsproblematik är ett eskalerande problem som har visat sig påverka många unga människors utveckling och välbefinnande. Syftet med denna studie var därför att undersöka ungas dataspelsproblematik, vilka konsekvenser ett överdrivet dataspelande medför samt vilken behandling som ges till unga med dataspelsproblematik. Empirin erhölls genom kvalitativa intervjuer med professionella som arbetar med denna typ av problematik vid verksamheterna Game Over och Theory in Action. Resultatet visade att dataspelsproblematik idag inte har en bestämd definition och att det är ett problem som inte är tillräckligt uppmärksammat. Synen på orsaker till dataspelsproblematik hos unga är komplext då det kan tänkas bero på många olika faktorer.
Synt och sånt : Datorbaserat musikskapande på folkbibliotek, en studie i förutsättningar och praktik
Recent papers and bills from the Swedish Government deal with the possibilities of giving all Swedish citizens the possibility of their own creative actlvities in the cultural sector. This work is about where such actlvities shall be placed in order to make them obtainable for all. As an example of creative work this work takes computer-based music-making. At the public library in Odense, Denmark there is a weil functioning sound workshop where the public gets the opportunity of making music with some assistance from the staff. This work shows that also in Sweden the public libraries are the most suitable institutions for placing studies for computer-based music-making for the public depending on the public libraries' traditions in adult education.
Dimensionering av betongplatta på lös undergrund. En jämförelse mellan tre beräkningsprogram
Today more effective computer programs are in use, regarding design of geotechnicalconstructions. There is a risk that the theoretical background of the computerprograms, its limitations and the signification of the choice of soil parameter isforgotten when the computer programs become more user-friendly.This Master thesis deals with simulation and analysis regarding three computerprograms, FEM-design, with the addition Raft, Plaxis and BE-slab. Comparisons aremade for settlement and maximum moment in a concrete-plate. FEM-design is a threedimensional FEM-program, foremost created for design engineers. Plaxis is a twodimensional FEM-program, intended for geotechnical engineers while BE-Slab is aBoundary elements program in two dimensions that is mainly used by designengineers.
DATORSTÖD FÖR ARBETE - KONSEKVENSER FÖR VAL AV AFFÄRSSYSTEM En studie av en service- och supportavdelning
This report is focusing on problems with introducing standard enterprise
resource planning systems (ERP) in businesses. A study has been carried out on
a service and support department at a Swedish heat metering company, SVM North
Node. The study aims to help the company become a better customer in choice and
customization of a new ERP system. We make a description of the department
studied and the work carried out there, on the basis of learning, knowledge and
cooperation. As a final point we present some ideas on how computer systems
could support their work, hoping that this will result in them making adequate
demands on a new ERP system.
Rekommendationer för införande av public key infrastructure
The use of insecure networks -such as the Internet- to send and receive information has made the need for preventing unauthorised people reading it yet more important. One of the easiest way to do this is through public key cryptography. However, the problem with this solution is how to tie a specific public key to a certain subject. This is solved by letting a trusted third party issue a certificate that holds, as a minimum, the name of the subject and the subject's public key along with the issuer's digital signature on the information. The rules we make for issuing, revoking and verifying of certificates and the entities that are being used to do so are called PKI - Public Key Infrastructure.
Hur biodiversitet på ekosystemnivå skiljer sig mellan olika habitat
Biodiversity can be described as the total variation of life forms, where diversity ranges from gene level up to the ecosystem level. The diversity can be calculated in a number of ways, and this study use one of these methods. In this study empirical food webs have been used and analyzed, where eleven characters are defined and used as parameters to calculate the Euclidean distances between food webs that describe the variation that may exist within classes of terrestrial, marine and freshwater habitats. The class who stood out and showed the greatest diversity at the ecosystem level was the marine food webs, which showed a high value of the average euclidean distance. The other networks were not as distinctive and the average of the euclidean distance in these classes was comparatively low..
Säkerhet i det trådlösa hemnätverket ? En analys av de vanligaste säkerhetslösningarna
The security solutions used in wireless home networks are examined in this report. Thegrowing number of wireless units have increased the need for reliable security solutions.This report aims to enlighten the reader about the fundamental technology used inwireless security solutions and inform about the existing flaws. A recommendationabout how to achieve a high level of security in the home network is also given to thereader.Several flaws in the security solutions in use have been reported. Of these the mostsevere has been examined in a test network using highly accessible tools to get aperception of how vulnerable the user is.The tests showed that several attacks were efficient and easily carried out. We have alsoseen that several of the home networks in our sample are susceptible to these attacks.Our survey revealed that the Internet service provider's technical support in many caseslacked the knowledge necessary to inform the user about reliable security solutions..
Invandrares nätverk och sociala kapital
Abstract The increased focus on social capital theory has made its way into labour economics. This has led to the creation of a vast literature about the use of networks and informal search methods in the labour-market, a literature that to some extent also deals with immigrants search behaviour and their relatively high unemployment rate. Characteristic for the literature in the area is the lack of analysis of actual networks. Which types of contacts do these networks contain; how are the networks used in the labour-market; and which type of network generates a high amount of social capital. These questions are important for the general understanding of how social capital functions, within the labour-market, but also for the understanding of how immigrants use their networks in order to find themselves jobs.
Digitaliserade möjligheter för skolan : En studie av två spels pedagogiska potential för historieundervisning i grundskolan
This essay examines computer and video games and their capacity of being useful in teaching sessions. Focus is being put at a possible pedagogical potential and how it is being expressed in games mechanics. To get answers on these subjects? studies by Professor James Paul Gee and Jesse Schell is used together in creating a model for analysis. With this model together with a narrative analysis this essay hopes to give clarifications on if a pedagogical potential is present and if so, how it is being expressed.Studies in this paper shows that a pedagogical potential is overall present in used material.
Utvärdering av Near Field Communication och Certified Wireless USB: Säkerhet vid utveckling av applikationer
Today?s society is one where technological advances are made daily, which
increases the need to stop and assess the risks against users? integrity when
integrating new technology in contemporary systems all the greater. We have
taken two technologies, Near Field Communication and Certified Wireless USB,
whose envisioned area of use is to be integrated into mobile phones, and
evaluated what security threats are revealed for the respective technologies.
The threats against security have been identified through research of the
standards and existing reports for each technology. Practical experiments have
not been conducted on account of us not having access to any equipment to run
such trials.

Downloading and filesharing through Peer-to-peer networks: the copyright versus the free access to the cultural products
The “peer to peer†(P2P) is a technology of downloading and filesharing between online - Internet - users by the mean of specified software. Since June 1999, the Napster software has made the happiness of millions of individuals who used it to obtain and share free audio files Mp3.
Rapidly, the major recording companies have prosecuted the Napster Company and managed to force it to close down. They were arguing against it for it is supporting the development on a large scale traffic of files protected by copyright and thus was threatening the whole music and movies economic world. Since fast Internet connections multiplied, "peer to peer" software and networks improved, so that this mode of exchange became an unprecedented success.
Today all cultural products, in particular films and music, are concerned with this free –of– charge distribution without any financial counterpart for the copyright holders. Two tools hold
today the top ranks and concentrate large traffic: eDonkey and eMule.
