Komplement, konkurrent eller verktyg : Aktörsperspektiv på datoranvändning på en förskola
Syftet med studien är att undersöka och belysa synsätt på datoranvändandet som pedagogiskt verktyg i förskolan ur pedagog-, barn-, föräldra- samt skolledarperspektiv, det vill säga ur olika aktörers perspektiv. Forskning om datoranvändande i förskolan är marginell, varför ambitionen med studien är att i någon mån bidra till kunskap inom området. Ljung-Djärfs avhandling Spelet runt datorn - datoranvändande som meningsskapande praktik i förskolan har använts som inspirationskälla då delar av hennes resultat har legat till grund för våra frågeställningar: Vilken syn har aktörerna på datorn som ett pedagogiskt verktyg i relation till andra förekommande aktiviteter? Hur ser aktörerna på datorns tillgänglighet som val i förskolans verksamhet? Hur uppfattar aktörerna datorns relevans som pedagogiskt verktyg i förskolans verksamhet? Studien har en kvalitativ ansats i form av en fallstudie och har genomförts på en förskola i Mellansverige med hjälp av intervjuer, enkäter samt observationer. Resultatet pekar på tre synsätt på datoranvändandet som pedagogiskt verktyg i förskolan ? en kompletterande aktivitet, en konkurrerande valmöjlighet och ett verktyg i lärande.
Arbetsgivares förhandlingsskyldighet
This paper focuses on the employers? responsibility as described in the 11th section in the Employment (co-determination in the workplace) Act of 1976. The questions asked are to determine whether the law in the 11th section is followed in real life and if the consequences for breaking the law are a deciding factor. This paper summarizes the law as it is interpreted today and in what situations it is applicable. Since the law and especially section 11 affects certain individuals and organizations, the paper also describes who these individuals and organizations are and how they are affected.
Implementering av immateriella rättigheter i Kina - One size does not fit all
Piratkopiering i Kina har varit ett ämne som flitigt debatterats internationellt de senaste åren. Denna uppsats ämnar analysera åtgärder vidtagna för att implementera immateriella rättigheter i Kina i en ekonomisk, politisk och historisk kontext. Sedan Kina gick med i WTO har landet varit tvunget att ändra sin lagstiftning inom många områden, speciellt rörande immateriella rättigheter. Positiva och negativa aspekter av full implementering av dessa regler i Kina analyseras även..
Förklaringsmisstag : - i ett elektroniskt sammanhang
The thesis hears content-error in relation to agreements closed by electronic means. The purpose of the thesis is to elucidate how the rules in 32 §(1) AvtL apply to agreements closed by such means and to evaluate its suitability. The elucidation is done on the basis of, the rules? adequacy in relation to their objectives in collaboration with a comparative view on a selection of international legal framework under private law, such as DCFR, UNCITRAL Model Law, UNIDROIT Principles and CISG.Since Sweden lack a specific regulation for electronically closed agreements, all modern closing methods will be evaluated from the dated outlook of the Swedish Contract Act. In relation to entirely automated processes which results in the closing of an agreement, particular difficulty arise in correlation with prerequisites, which requires a human stance.

Hållbar Utveckling 2010 : Hur uppfattar lärare begreppet idag?
This work is a study of subject teachers in social studies and science understand the concept of sustainable development. The work uses a qualitative and a quantitative approach. Teachers in various schools and stages have been answering questions about how they perceive sustainability, how they implement it in teaching and if they feel that school is important for the future of sustainable development at large.The theoretical background is based on environmental ethics as well as the different meanings and definitions of the concept of sustainable development. These theories and definitions are coupled with the empirical results.The study concludes that all teachers throughout the study perceive the concept of sustainable development as something ecological, something that has to do with nature. A few teachers also state economic and social dimensions.Questions about how the teachers in the study implement the concept in their teaching can be seen as three different approaches.
European Food Safety Authority - En studie av legitimitet i en europeisk expertmyndighet
This essay analyses the European Food Safety Authority's (EFSA) legitimacy. Theories on input- and output legitimacy are used in the examination. After analysing stakeholder representation, forum for deliberation, transparency, independence, and information sharing, input legitimacy in EFSA is assessed to be high. Output legitimacy was examined through the authority's outcome effectiveness, which was divided into compliance and effectiveness. Since food safety is an immense area, two important parts were chosen for the analysis of output legitimacy; transmissible/bovine spongiform encephalopathy (TSE/BSE) and genetically modified organisms (GMO).
Kontrollerad vokabulär eller naturligt språk? En empirisk studie.
The question whether controlled vocabulary or natural language free-text terms is the most effective search strategy has occupied researchers in LIS for many decades. This Masters thesis is an empirical study which aims to compare these two search strategies in LISA Library and Information Science Abstracts, an online bibliographic database. 22 topics from the discipline of Library and Information Science were constructed and out of each topic one query for each search strategy was formed. Queries in natural language were formed with terms from different sources, for example dictionaries, while queries in controlled vocabulary were built with terms from LISAs electronic thesaurus. The measures used in this study were precision, relative recall pooling method and overlap.
Automatisk mätning och detektering av röjande signaler
This master thesis has been performed at Sectra Communications AB in Linköping where they manufacture electronic encryption devices. In cryptology it is essential that an eavesdropper cannot find the plain text. To assure that a system is safe, all devices are thoroughly examined so that they don?t emit any secret information, so called Compromising Emanations (CE). This is done by comparing the secret signal with measured signals on the screen of an oscilloscope, a process that is very time consuming and furthermore, the risk of missing compromising emanations is high.

Studie av konstruktion och implementering av CORDIC-algoritmer
Abstract CORDIC (Coordinate Rotation Digital Computer) is an iterative algorithm for the calculation of a two-dimensional vector in circular, linear or hyperbolic coordinate systems. This paper presents a survey of known CORDIC algorithms and architectures for the rotation and vectoring mode in the circular cordinate system. In addition an implementation of the differential CORDIC algorithm in VHDL has been done. The implementation is designed to keep the fast timing and throughput characteristic known for on-line redundant arithmetic..
Klickers ur ett studentperspektiv : Studenters uppfattning av klickers vid Uppsala universitet
Audience responese technology (ART) often called clickers are becoming more common, not only internationally but also at Swedish universities. No direct Swedish research has been identified, this is however a major area of research internationally. There is both research on clickers positive effect on study results and how students feel about using clickers. This study has taken a Swedish translated version of Cheesman, Winograd, and Wehrman?s (2010) survey to investigate how perception of clickers differ between students in Disciplinary Domain of Medicine and Pharmacy and Disciplinary Domain of Science and Technology.
Synkronisering med SyncML
The last couple of years the use of mobile devices such as mobile phones and PDAs has increased tremendously. Most of the these devices have their own protocols for synchronising data and this has given rise to a need for a standard synchronisation protocol, SyncML. This thesis compares this protocol against the existing ones. The comparison shows that the preferred choice is SyncML. Also an application using SyncML has been developed.
Design av försöksanläggning för trycksatt rökgasrening vid oxy-fuelförbränning
Reducing the CO2-pollution, resulting from the combustion of fossil coal for energyproduction, is important to affect environmental changes. One way to achieve a reductionis to use the oxy-fuel technology. The technology uses O2 and re-circulated flue gasduring the combustion which results in a flue gas mainly consisting of CO2. The flue gascould then be compressed and stored without environmental effects. A problem thatfollows from the compression is the risk of acidification in sensitive parts of the process.Acidification can occur because of reactions following from the contact of condensedwater and sulphur- and nitrogen-oxides which are also present in the flue gas.This report compiles and evaluates the basis of a scientific unit with the purpose ofexploring the possibilities of extracting impurities of SOx and NOx from the flue gases.The dimensions of the unit are based on basic conditions, defined for an existing oxy-fuelprocess at Chalmers, and on the results of computer modelling.
Parprogrammering - Ökad tidsåtgång uppvägs av dess fördelar?
Syftet med arbetet var att ta reda på om den ökade tidsåtgången som
parprogrammeringen leder till uppvägs av de fördelar som den genererar i
jämförelse med enskild programmering där arbetet delas mellan två programmerare
och sedan integreras. I arbetet presenteras resultatet från en
enkätundersökning som sju personer från fyra olika företag i Sverige har
besvarat. Samtliga personer som besvarat enkäten har arbetat både med enskild
programmering och parprogrammering.
