MiFID - En analys av direktivet om marknader för finansiella instrument och dess inverkan på kundens ställning på värdepappersmarknaden

This essay aims to analyse the Markets in Financial Instruments Directive, formally called MiFID, andwhether it improves the situation of the investor, the customer, on the market for securities. MiFID isa directive from the European Union and was implemented by the member states in 2007. Besideshaving the objective to harmonise the European financial market, the directive aims to increasecompetition and efficiency among the markets in the member states.After our initial reasearch in the area we choosed to do a textual analysis and divide the content ofMiFID into three main areas: trading venues, transparency and investor protection. These areas aresubsequently analysed in relation to the investor?s situation on the market for financial securities andthe overall question at issue is whether MiFID improves the situation of the investor.

REX DVD : Om framställningar av kung David spelande på stränginstrument i bilder från tidigmedeltida manuskript

The purpose of this work was to investigate the early medieval view of the Bilical king David through the analysis of ten illuminations found in early medieval manuscripts in which he is depicted playing string instruments. First, a description of medieval manuscripts and king David and string instruments was presented, second, an analysis and a discussion of images as source material and an interpretation of the mythic and symbolic significance that is based on ideas presented by Paul Ricoeurs and Roland Barthes of the ten illuminations followed. The results showed that king David often was portrayed as a musical king, a dancer and a prophet that incarnated wisdom and justice; that king David served as a role-model for the Western regents, and that he was portrayed in an idealised and estethically appealing manner..

Programmering av styrutrustning för vridbord vid radarmätplats

Vid kalibrering av en radars antenn placeras radarn på ett vridbord som kan rikta in den mot en mast. På masten sitter ett kors som används som riktpunkt. Huvuduppgiften i examensarbetet var att skriva ett program i National Instruments programmeringsmiljö LabVIEW som kan ställa in vridbordet med en noggrannhet på 0,1 milliradianer. Programmet ska kunna användas som ett DLL (Dynamic-link library) i LabWindows/CVI där ett antal olika funktioner ska kunna anropas för styrning av vridbordet. Eftersom nästan all maskinvara är från National Instruments blev programmet väldigt lätt att skriva.

Som en schackpjäs : om socialsekreterares upplevelser av sin yrkesstatus vid handläggning av försörjningsstöd

The purpose of this essay has been to answer the question of whether or not administrators of economic support perceive that their professional status is ranked lower than that of their coworkers in other fields of the social services. We set out to study whether or not their comparative status differed depending on their use of standardized assessment instruments and if their experience with regards to professional status differed depending on the size of the municipality they worked in. We also wanted to determine in what way (if any) the comparative status manifests itself and what factors influences it.We?ve utilized method triangulation in order to answer the questions posed in our purpose. The quantitative study was conducted using a questionnaire and the qualitative with three interviews.

Utveckling av inbyggda system med grafisk programmering

The increase of complexity in embedded programming is forcing the development of higher level programminglanguages. These languages not only consist of traditional text based programming but also with graphical programminglanguages such as the programming language G from LabVIEW which is developed by National Instruments and havebeen around since the mid eighties. However since 2004 this language has also been able to program embeddedhardware, using the modules LabVIEW SDK and LabVIEW for ARM. This thesis shows how LabVIEW for ARM converts itsgraphical language G to C and then how C is flashed into the microprocessor. The thesis also takes up the pros and consof using G for embedded development.

Digitala och sociala medier i undervisningen för elevers ökade motivation, delaktighet och måluppfyllelse.

The aim of the study was to examine both 1) how aware teachers in a specific area are about ICT tools in teaching ; and 2) how likely teachers are to use ICT tools to reverse the trend of unmotivated students and low achievement scores . I will look for answers through the following questions:How extensive is the knowledge of the teachers on digital and social media in education? How have teachers in the past year used various social media in their teaching? In what grade does ICT-supported teaching lead to higher motivation, participation and achievement? Is there a difference between the sexes, different stages (1-3, 4-6, 7-9) and number of years in the profession in knowledge of and openness to the use of ICT in education?The method used is a questionnaire in which a number of respondents have answered a number of questions about ICT tools in teaching. Validity of the study can be said to be high when the survey has measured what it intended to measure, however, I need to be careful in draw full account of the result as the response rate is low with only 39%. In summary, the results show that there is low awareness among respondents about the methods and the digital and social tools I lift in the survey.Mainly the respondents use some of the methods and the digital and social tools in preparation for the lesson.

Nej, inte rita. Låna!: 3-4-åriga barns informationsbeteende på folkbibliotekets barnavdelning

The aim of this study was to examine how children in ages 3 to 4 use the public library with the research questions: What does children?s, in ages between 3 and 4, information behavior look like when they visit a public library in leisure time with a parent? What is the nature of interaction between child and parent, child and the staff of the library, and between child and other visitors? What is the function of the cultural tools in relation to the children?s information behavior? The theoretical frame of reference consisted of Lev Vygotsky?s ?the zone of proximal development? and Roger Säljö?s theory about using cultural tools. To answer the questions I have observed 4 children together with their mothers and siblings at a public library. From the result of the observations I found that every child had their own information behavior. Two of the children only used one kind of cultural tool ? books.

ELCERTIFIKAT - En diskussion kring de svenska elcertifikatens rättsliga natur, ekonomiska värde samt möjlighet att ta i anspråk vid en utmätning -

1st of may 2003, a new energy system based on electricity certificates, was initiated in Sweden. The purpose with this system, is to stimulate an enlargement of energy production from renewable sources. The electricity system, ist built on that the producers of energy from renewable sources confer a electricity certificate from the government for every produced MW energy from renewable sources. The electricity certificate is supposed to be turned over and with that generate reciepts to the producers. Furthermore there is an obligation for the energyusers und energysuppliers, that means that the users and the suppliers every year the 1st of april got to have electricity certificates in proportion to their energy consumption during previous year.

Working with spontaneous communication : A workplace study on the use of technical tools and social praxis in the collaborative work at two smaller design-companies.

This paper presents the results of a workplace study of two smaller companies in the design industry. The core issue has been to investigate the companies use of technical tools and to what extent social praxis influence the daily work. The methods used are based on a qualitative analysis of interviews and observations. Various kind of work procedures, such as verbal and computerized, have been identified, but the most important occurrence was how spontaneous conversations between employees required certain flexibility, since the actors repeatedly were required to change focus and quickly perceive different information. For that reason, a thesis has been defined regarding how the use of spontaneous communication put an indirect need of a flexible working environment and also how this lead to more significant participation and exchange of information, as well as more awareness at the companies..
