Att läsa matematik - det handlar om kontexten

Syfte: Syftet med studien är att undersöka och belysa relationen mellan läsförmåga och förmågan att lösa uppgifter i matematisk problemlösning. Centrala frågor: Vilket samband finns mellan läsförståelse och elevernas möjlighet att lyckas i problemlösning med matematiskt kontextualiserade problem?På vilket sätt kan förståelsen av ord- och begrepp i vardagen, som i en matematisk kontext får en annan eller utvidgad betydelse, påverka elevernas problemlösningsförmåga?Kan man se likheter och skillnader i resultat mellan matematiskt kontextualiserade problem och motsvarande problem i matematiskt kontextlösa uppgifter? Vilket samband finns mellan läsförståelse och elevernas möjligheter att lyckas med aritmetiska, kontextlösa uppgifter?Teori: Formulering av forskningsfrågor och analys av resultat utgår från en socialkonstruktivistisk och sociokulturell förståelse. Studien bygger på kvantitativ metod som analyserats med hjälp av statistiska grundteorier. Metod: Metoden i undersökningen är kvantitativ.

Vilken är den teoretiskt optimala toppdiametern på bokmassaved vid motormanuell avverkning?

The bioenergy market has been introduced relatively late in a perspective of the Swedish forestry. Nowadays branches and tops are used more frequently as bioenergy after harvesting. Therefore, it has developed a competitive situation between pulpwood and bioenergy. This situation has even established some questions. Two examples of these are: ? At what top diameter should the final piece of pulpwood be crosscut to get the best economically result? ? Should the top diameter, at the final piece of pulpwood, be crosscut at a thicker or smaller diameter than what is done today? The purpose of this report is to answer these two questions when the harvesting is made motor manually in beech stands.

PRAKTISK BESTÄMNING AV KLÄMKRAFT OCH FRIKTION I SKRUVFÖRBAND

This report reflects an examination work performed for Getrag All Wheel Drive AB during the spring of 2005. Among the companies range of products there exists some concern regarding the amount of clamping force and friction on bolted joints caused by the assembly torque.The aim of this project has been to determine if there is a simple way in which to identify and then practically apply testing methods for clamping force and friction through utilization of existing testing equipment.Three separate methods of clamping force and friction determination have been tested in rear drive unit, RDU, at a 30 Nm assembly torque. A fourth and final method, screw elongation with ultrasound, has been used as reference. The methods are:?Torque-Tension test.?Screw elongation with micrometer.?Joint stiffness test.?Screw elongation with ultra sound for reference.The results from tests can be viewed in table below.MethodTorque-TensionMicrometerCs=318 kN/mm Assembled with torque wrenchMicrometerCs=318 kN/mm Assembled on lineUltra-soundCS=311 kN/mm Ultra- soundCS=318 kN/mm Joint stiffnessTheoreticalClamping force-21,8 kN17,6 kN17,3 kN17,6 kN17,1 kN17,3 kNFriction-0,110,1470,1530,1470,1520,149.

Effekten av fonologisk träning enligt Bornholmsmodellen på elevers språkliga medvetenhet i årskurs 1

Denna rapport är en del av en longitudinell studie av psykolingvistisk ålder och språklig medvetenhet hos elever i årskurs 1 på två olika skolor i Vallentuna kommun. I studien har material från de tre senaste projektåren bearbetats. Syftet med undersökningen var att undersöka huruvida fonologisk träning enligt den s.k. Bornholmsmodellen under elevernas tid i 6-årsklass återspeglar sig i ökad språklig medvetenhet och högre psykolingvistisk ålder i årskurs 1. Vidare undersöktes om den fonologiska träningen kan ha påverkat barnens arbetsminne.

Söktjänster för akademiskt bruk. En jämförande undersökning mellan Google, Google Scholar och Scirus.

This paper is a comparing study of the retrieval effectiveness of the search engines Google, Google Scholar and Scirus. The aim is to find out how good they are at retrieving relevant academic material in the research-field of Library and Information science. The thirty search questions where based on actual information needs collected from exams within the field of Library and Information Science. This method was used to prevent that none of the search engines were given an advantage because of construction of the information needs. The first twenty retrieved documents on the retrieval lists are examined for academic content and relevance.

Ung, samtida och postmodern : En studie av det svenska konstfältet under 1980-talet utifrån Lars Nilssons konstnärskap

The aim of this thesis is to study the Swedish art field during the 1980s, from the perspective of the artistic production of Lars Nilsson. During this decade he became one of the most well known young artists associated with postmodernism.The thesis is divided into three parts, where the first part examines different influences and aspects of the art of Lars Nilsson, as well as the contexts he was a part of. This is performed through a chronological as well as a categorizing presentation, based upon different exhibitions where Nilsson participated during the 1980s.In the second part the subject is the Swedish art field, and how Lars Nilsson came to be part of a a new established category of a young generation of artists, mostly born in the 1950s, who were associated with youth, postmodernism and contemporaneousness. This part also puts attention to the importance of Lars Nittve, then art critic and curator, in introducing postmodernism, as well as establishing this new categorization of artists in Sweden.The last part of the thesis studies four different group exhibitions, and how they all exemplify how "a younger generation of artists" were to be connected with notions of postmodernism and contemporaneousness through curatorial practice. Lars Nilsson participated at the thirst three of these exhibitions.

Relationen mellan perception av prosodi och perception av tonglidning : En jämförande studie mellan normalhörande och personer med hörselnedsättning

Prosodi utgörs bland annat av variationer i tonhöjd, så kallade tonglidningar. Dessa tonglidningar förmedlar såväl språkligt som emotionellt innehåll i talet. Förmågan att uppfatta skillnader i tonhöjd kallas frekvensdiskriminering. Eftersom denna förmåga kan påverkas negativt av en sensorineural hörselskada är det tänkbart att hörselskadan även kan påverka perceptionen av prosodi. Syftet med studien var att undersöka om det finns ett samband mellan perception av tonglidningar och perception av prosodi samt om det finns en skillnad i dessa förmågor hos normalhörande respektive personer med en hörselnedsättning.

Nedskrivning av goodwill - en skyldighet eller möjlighet?

The purpose with this thesis is to demonstrate that other factors than the existing set of rules could influence the Management Group?s decision in regards to depreciation of goodwill. We have explained the conflicts between the management group and the stakeholders by using the Agency Theory and the Stakeholder Model. We have used the Positive Accounting Theory to describe how the management group?s opportunistic behaviour decides which accounting method to use.

Den kommunala folkhälsosamordnaren söker sin arbetsroll

Coordinator of public health has recently become a new profession in the field of Health Promotion. During the last few years the pedagogic perspective has been increasingly important for the coordinators as a way of adapting their work methods to the circumstances. The conditions for coordinators of public health differ between municipalities and thus their tasks and responsibilities may vary with the local structure. According to the literature there are several ways to conduct Health Promotion and it is in the hands of the coordinator to adjust the methods to fit local conditions. The purpose of the study was to examine what influences the coordinators of public health and how that affects their work methods.

Ett slott i romantikens lövsal : skogsutveckling på Château du Grand Val - att utveckla en integrerad gestaltande skogsbruksplan

The work presented here aims to give the owners ofChâteau du Grand Val, Roland and Marie Nilssond?Aubigné an integrated creative forest management planin which their goals with the property is heeded, andwhere the plan is so clear that they can follow it withoutmuch difficulty.This work has come about through the normal processesof forest management plans, landscape architecturalproposals as well as through field trips, field andliterature studies, and our combined experience fromour studies. The study visits, both on location in Brittany,France, but also in other places, as for instance Högestad,has provided the background information that formedthe basis of our analysis and the proposal that is derived thereof. Some suggestions, which we consider importantto the overall impression of the property, is provided amore focused and detailed solution, while other parts,which are important but can either benefit from havingdynamics in the design process or will be adapted toadjacent sites, are developed using a more generalapproach. In some cases several possible developmentprinciples are presented.The proposal presents a detailed plan for themanagement of the forest from the experience, wildlifeand forestry economic standpoint.

Förbättrat råvaruutnyttjande vid kvalitets-sortering av timmer : utvärdering av analysprogrammet Stockholmen för automatiserad timmersortering i dimensions- och kvalitetsklasser hos BARO WOOD AB

The aim of this thesis was to analyse BARO WOOD AB:s timber measuring and quality sorting and to evaluate the analyse program Stockholmen. The purpose was to get a better understanding for the quality sorting made at BARO WOOD AB today, analyse differences in center board quality from logs with a good quality and logs with a bad quality, suggest new sorting criterias developed from analyses made with Stockholmen and to evaluate the program Stockholmen. All analyses are based on data gathered in a test sawing made at BARO WOOD AB in June and July 2002. The test sawing was made on four different diameter classes and every diameter class consisted out of A or M-grade logs, with a better quality, and B-grade logs with a lesser quality. The logs where sorted out with BARO WOOD AB:s existing quality criterias.

Kalkningens påverkan på fosforlöslighet : skakförsök baserade på två svenska långliggande kalk- och fosforgödslingsförsök

Eutrophication is an environmental problem that affects more than ten percent of Swedish lakes. Excess nutrients increase the growth of algae, and cause major problems in the ecosystem through oxygen-free bottoms, fish kills, and at worst dead bottoms. Agriculture accounts for 44% of human emissions of phosphorus to lakes and rivers. Leaching occurs of particle bound phosphorus and of dissolved phosphate. The amount of phosphate in the soil solution that may be leached is partly due to the prevailing pH in the soil solution. The purpose of this study was to investigate how the relationship between phosphate solubility and pH was affected by liming.

Analys av data från flyglaserscanning :

In forestry there are always needs of forest data to make good strategic decisions of different actions and economic winning. Usually this data gets from field-estimations made by forest workers with expensive costs and sometimes unsatisfied quality. StoraEnso Skog is a great forest company in Sweden and they have part of the responsibility of the forest own by Bergvik Skog. Bergvik Skog is owner of 1, 9 million hectares productive forest land. Both Bergvik and StoraEnso have great interest in new inventory techniques to get the important forest data. The company Foran Remote Sensing offers the opportunity with airborne laserscanning of forest and forest land. Foran got the mission of Bergvik and StoraEnso to laser scan Bergviks possession in Älvdalen, Dalarna.

Att inleda ett arbete med CRO inom webbutvecklingsföretag

This study test the short-termism of companies listed on the market OMX Stockholm 30. We will use a deductive point of view where the purpose of this study is to investigate whether corporate short-term returns can be explained by the independent variables related to corporate governance and compensation practices. This is to investigate whether there is an intentional action on raising the short-term return in order to achieve a higher CEO compensation. In the study, theories dealing with corporate governance and agency theory have resulted in two hypotheses. Basic Hypothesis H1 is: if short-termism of Swedish industry due to the company's short-term returns can be explained by the independent variables related to the company's management and compensation. This hypothesis could not be verified through the quantitative study. Alternative Hypothesis H2 is: the compensation of a CEO can be explained by the independent variables related to company performance and size.
