En studie om det laborativa materialet i bråkundervisningen utifrån elevernas perspektiv Författare: Ruzica Pajic Syftet med denna studie är att uppnå en djupare förståelse om det laborativa materialets betydelse i skolans matematik. I detta magisterarbete har det undersökts hur barns perspektiv påverkas i årskurs 6 utifrån hur laborativt material används i matematikundervisningen. I tidigare forskning redovisas barns lärande och hur den skildras utifrån kognitiva, kulturhistoriska och sociokulturella perspektiv. Bland dessa perspektiv presenteras och jämförs teoretikerna; Vygotsky och Bruner med varandra. Dessa teoretiker har valts, eftersom de presenterar grunderna för användning av laborativt material i skolan.

The main purpose of this study was to examine how social work can be performed online, by a case study of Korrespondensgymnasiet that pursues distance education. The intention was to determine the possibilities and limits with the online communication between the school counsellor and the pupils. The study was based on qualitative semi-structured interviews with one school counsellor and five pupils and document analysis of three descriptions of the school counsellor?s profession. The theory that has been used in this study is the communication theory: Shannon and Weaver?s Model of Communication and non-verbal communication.

This is a study of the way power relationships change when women start to play candombe in Montevideo, Uruguay. Candombe is a type of music, which is traditionally played by men within the black minority in the country. This study has been done with an intersectional point of view, taking the social categories gender, class and ethnicity in account. The method used was participatory observation in a field study made in Montevideo between November 2008 and February 2009.This study?s main conclusions are that the power relationships change with the participation of women in candombe in several important ways: The women legitimize an alternative way to be a woman when they take the men?s role as a drum player.

Allt fler barn upplever skolmatematiken som ett svårt ämne, något som väcker tankar och reflektioner. Jag utgår från att det är viktigt att redan i förskolan förbereda ett arbetssätt så att barnens förståelse för matematik utvidgas. Syftet med min studie är att lyfta fram förskollärarens roll i arbetet med matematiken i förskolan. Jag har all anledning till att utgå från begreppen språk, material och miljö för att få vetskap om förskollärarens roll. Jag anser att dessa begrepp är så sammanhängande med varandra och tillsammans utgör grunden för allt lärande. Studien är kvalitativ och består huvudsakligen av observationer som metod.

The purpose of this paper was to identify the elements and the alloys that five objects found in Birka consist of and to examine whether there are any significant differences between the presumably imported and domestic objects. The material was analyzed using a scanning electron microscope (SEM) which was equipped with an energy dispersive X-ray spectrometer (EDS) in order to identify the elements that are present and the alloys that the objects are made of. Then the SEM results were compared with the results of previous analyzes that have been performed on finds from Birka in order to investigate how the objects differ in elemental composition and to find out if there are any significant differences between them. The results showed that the objects? content of the elements analyzed varies as the copper alloys the objects are made of.

The purpose of the study was to evaluate the function of TalkingMats in a group of people with Huntington?s disease, with main focus on theeffectiveness of communication. Four individuals with Huntington?s diseaseand their group leader participated in the study. The group was videotapedduring four sets of conversations; two with and two without Talking Mats.

Hedge funds have the past few years become an increasingly popular investment alternative and in the last decade hedge fund assets managed have quadrupled to USD 2000 billion, a growth rate of around 25-30% per year. One explanation for this substantial increase is that hedge funds' minimum limits on capital invested has declined, which have made ??them available to retail investors. The recent turmoil in financial markets has also contributed to investors finding their way to hedge funds, whose goal is to generate stable returns regardless of how the market develops.Using Sharpe?s, Treynor?s and Jensen's performance measures, I have investigated whether hedge funds manage to generate higher risk-adjusted returns than traditional managed funds.

For research purposes Saab has developed a generic mathematical model denoted VEGAS of an aircraft with a configuration similar to JAS 39 Gripen. Today parts of Gripen backup control system are used also for VEGAS making the system subject to both corporate and defense secrecy. The main objective of this master thesis is to design, verify and implement public pitch axis flight control system for VEGAS. Furthermore, simplifications regarding the design process is to be examined. Design of pitch axis flight control system for the entire flight envelope has been carried out.

The purpose of this essay is to investigate which components previous scientific studies suggest that an efficient treatment for adolescents with behavioural problems should contain. For this purpose, an extensive review of scientific research conducted in Scandinavia has been read and will be presented in this essay. This essay also present an introduction to residential care in Sweden as well as to an alternative form of treatment for adolescents with behavioural problems called Multidimensional Treatment Foster Care (MTFC). The result of this essay suggest that treatment of adolescents with behavioural problems should be based on the emphasis of risk/resilience factors of the youth and that the treatment should be adapted to the youth?s individual personality and way of learning.

Detta examensarbete utreder hur information kan anpassas textuellt och formges efter en specifik målgrupp. Informationen behandlar explosiva och energetiska material, var de används och av vilka, och hur hanteringen sker säkert. Arbetsprocessen har innefattat metoder för textanalys, fokusgrupp och jämställt språk och har lett fram till ett designförslag. De texter som har analyserats har dels varit tagna från examensarbetets samarbetspartner, KCEM, och dels tagna från andra branscher som genom målgruppsanpassat material informerar om sina möjligheter. En fokusgrupp sattes samman av ett representativt urval av målgruppen.

The aim of this thesis was to use qualitative approaches to show how four preschool teachers experienced their start in the profession as a preschool teacher. The questions in the stydy were as follows: What kind of expectations did the preshool teachers have before the start in the profession? What did the preshool teachers experience as difficulty and opportunity at the start in the profession? How do they think now about their professional development during the early period in the profession? The empirical material, I got through a qualitative interview method. My theoretical starting point was to take the hermeneutic research perspective, aimed for interpreting and understanding. Theories of Socialization and socialization for teachers, socio-cultural theories and theories of tacit knowledge have been used to analyze the material.

Increased understanding of the mechanisms that operate in conjunction with the welding of metal surfaces may help to improve existing manufacturing processes, and to enable new products and combinations of materials. The purpose of the project has therefore been to acquire a deeper understanding of what is happening in the bond for steel and for the factors that form the basis for a bond to develop between metals in the production of laminates by pressing. The merge has been done by pressing and the surfaces after the experiments have been studied in detail in the scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX) and with interferenceprofilometry in Wyko, to provide a greater understanding of the mechanisms that influence the bonding in the interface between metals. The project was limited to contain the materials Docol 1000, HyTens 1200, Aluminum AA3003 and a commercial steel. The parameters varied in the experiments to study their influence closer are temperature, pressure, heat treatment and pretreatment. This has been implemented by pressing with varying temperature and pressure.

Marksaneringar görs idag i syfte att förhindra spridning av föroreningar till människa och miljö. Den vanligaste metoden för marksaneringar är att massor grävs upp och transporteras iväg för behandling. De flesta saneringar i Sverige görs i torra material såsom jord men även saneringar i sediment och andra blöta material genomförs. Vid sanering i blöta material avvattnas ofta materialet för att minska kostnader i samband med transport och förbränning. Ett material som hög förmåga att binda metalljoner och som dessutom kan hålla kvar mycket vatten är torv.

As today, companies are facing an increasing competition; markets are expanding while customers are getting more informed and fastidious toward companies and their products. For this reason it is crucial for enterprises to create loyal customers, or at best hyper loyal customers. With today's prerequisite this creation is difficult and it is therefore of highly interest to examine possible and alternative ways for enterprises to attain this type of hyper loyal customer. In this thesis we have examine hyper loyal football supporters with the aim to identify mechanisms that create and characterize this type of loyalty. By means of a survey and a focus group we were able to identify six loyalty mechanisms; the ability to influence, vicarious achievement, self-esteem, group affiliation, family and social relations.

24 years have passed since the Chernobyl accident when radionuclides were spread over largeareas of Europe, including the Scandinavian countries. Today, measurable activities of 137Csare still observed in many Swedish ecosystems.Ants (belonging to the order Hymenoptera) are social insects which collect organic materialfrom a large area around their nests. This study focuses on the 137Cs activity in ant nests andthe cesium accumulation in these nests. The aims were (1) to estimate the 137Cs fall-out in1986, (2) estimate the radiation exposure of ants and (3) find how 137Cs is distributed in an anthill. Seven ant hills (occupied by the species Formica polyctena) were studied near the villageof Hille, situated north of the city of Gävle in central Sweden.
