Denna litteraturstudie avser att sammanställa och redovisa vetenskapligt granskade artiklar som behandlar skillnader hos elever i matematiksvårigheter och elever i matematik- och lässvårigheter. Studiens resultat visar att matematiksvårigheter och lässvårigheter är beroende av varandra. Resultatet påvisade skillnader hos elever i matematiksvårigheter jämfört med elever i läs- och matematiksvårigheter i deras arbetsminne, fonologiska medvetenhet och problemlösningsförmåga. Det finns även stöd från forskningen att elever i matematik- och lässvårigheter har signifikant sämre resultat i arbetsminne, fonologisk medvetenhet och problemlösningsförmåga..

From 1710 to 1713 the plague raged through the Swedish province of Scania. Other studies have been made on how the disease affected the society during the epidemic. This study tries to focus on the recovery afterwards. How did the population and the farmsteads recover after the plague? Statistics from parish registers and cameral records show interesting patterns in the demography, and that the recovery was far from complete 1720.

The first part of the thesis consists of a brief introduction to the general principles of target detection and the sensor-systems used. In the following part there is a theoretical description of the algorithms this thesis focuses on. The detection algorithms described in this paper are called Cell Average, Ordered Statistics, 2parameter and Gammadetector. Two different discriminators called Extended Fractal Features and Quadratic Gamma Discriminator are also described. The algorithms are tested on three different types of data, simulated SAR-pictures, authentic SAR-targets and IR-pictures.

Problem Faith in the power of advertising has varied largely through the ages, and since we know that advertising is paid for, it therefore has less weight than the usual news. Publicity through promotional activities is in turn difficult to control. The question which of these two ways to communicate with the market that is the most effective, is equally entitled to ask, as difficult to answer. Purpose/Aim This paper is designed as a pilot study with two different objectives that go hand in hand. The first overall aim is to investigate how advertising and PR / publicity can be measured with the same tools while designing this metric.

I mitt examensarbete har jag studerat ämnet matematiksvårigheter. Syftet med arbetet var att få ökad kunskap om matematiksvårigheter samt ta reda på hur läraren kan hjälpa elever med dessa svårigheter. Jag har dels gjort en litteraturstudie och dels en empirisk studie. I min litteraturstudie söker jag fakta som är relevant till mina frågor. Den empiriska studien är gjord i form av intervjuer.

I detta arbete har textuppgifter i fyra vanligt förekommande matematikläroböcker ämnade för gymnasieskolans kurs Matematik A undersökts. Syftet med undersökningen har varit att ta reda på hur dessa uppgifter knyter an till verkligheten. Som undersökningsmetod valdes textanalys med utgångspunkt från ett antal egenformulerade analysfrågor, inspirerade av den litteratur som jag tagit del av. Resultatet av textanalysen visar att det är en förhållandevis liten andel av läroböckernas textuppgifter som har en trovärdig förankring i verkligheten, där endast ett fåtal av dessa beskriver en situationskontext som kan relateras till elevernas verklighet. En viktig slutsats som kan dras av detta resultat är att det finns en konflikt mellan de mål som står skrivet i de nationella styrdokumenten och innehållet i läroböcker som används i matematikundervisningen..

The title of this study came about from the title of Robert Putnams book Bowling Alone, where Putnam mentions that less people are bowling in teams than before. Bowling is still a large leisure activity in the USA but people tend to bowl more and more in small groups and less in organized teams. This study deals with social capital and leisure time. Its aim is to find out if some Swedish people create social capital on their leisure time and also how do they spend their leisure time. Robert Putnams book Bowling Alone serves as main background material along with the work by Bo Rothstein.

This essay is about the question if there is any difference in quality at the homes for the elderly in Skåne, depending on however the home is run by a public organization or private counterpart. The quality of the homes is meet with the help of numbers in ?the guide for the elderly? the facts in the guide are collected and judged by the ?Swedish National Board of Health. The result from the guide is divided into seven areas of quality, and then compared in a statistic test between the different types of organizations. And finally the result of the statistics is put in the context of the theory of New Public Management.

In fisheries, there is a long tradition to use catch data when evaluating changes in the stock and effects from harvesting. It is a common practice to use Catch Per Unit Effort (CPUE) as an index of population size, and several studies have investigated the properties of CPUE in relation to population abundance, spatial distribution and efficiency of gear. In research, catch rate on trap-transects is used as an index of abundance for wildlife species but CPUE is rarely applied as a tool in harvest management.In 1993, more than 60 000 km2 of the state managed mountain range in Sweden was opened to the public for small game hunting, under the responsibility of the county administrative boards in Jämtland, Västerbotten and Norrbotten. The total area is now divided into 332 hunting units (median=73 km2) and an internet based system is used to administer licences and reporting bag statistic. Each hunter has to register the results within two weeks after the hunt.

As for today, a large quantity of protein feeds is imported from other countries to be used in the Swedish dairy production. The main import is soya from Brazil. The soya-production in Brazil results in negative consequences for the natural environment in the area, and the long transport of the feeds requires a lot of energy. The organic dairy production in Sweden is, with the highest probability going to be forced to use 100 % organic feed to the cows in the year 2005, due to new EU-rules. These are some of the causes why there are reasons to look closer at the possibilities to feed Swedish cows with only Swedish feeds. In this study, I have looked at the KRAV-rules for organic feeding, where the goal is feeding with only KRAV-approved feeds.

The purpose of the study is to examine the multilingual student?s use of IT in school.The study also highlights the teacher?s view of development and how they use IT in their own teaching.A qualitative approach study was conducted to acquire a deeper understanding of students' language learning by using IT. In the study, it was assumed socio-cultural perspective in which learning takes place through interaction with others.The result shows that multilingual students have difficulty understanding information available on the internet and they are either waiting to meet a teacher to get a clearer picture of what to do or doing tasks even though in some cases misunderstand the task. Language teachers also confirm student?s impression and at the same time express the concern that students are reading less.This study shows that there may be correlation between students' learning motivation and an understanding of instructions online.

Syftet med detta examensarbete är att sammanställa maskinkostnader för etableringsmetoderna plöjningsfritt och konventionellt. Vi vill även titta på hur stor kapacitet som behövs på maskinparken för den tänkta gården på 600 ha åker, detta för att hinna etablera grödan inom ett rimligt tidsspektra. Anledningen till att vi valt ett företag på 600 ha är att det är den areal tröskan klarar av att avverka inom rimlig tid. Det medför att vi måste ta en del hänsyn till lägligheten och hur mycket av tiden som är så kallat ?tjänligt väder?.

Syftet med studien var att undersöka om en matematisk diagnos kan användas för att bedöma hur likvärdigt betyg sätts. Studien visar att diagnosen indikerar skillnader i likvärdighet som ligger i linje med tidigare forskning. En mer detaljerad undersökning där diagnosen jämförs med nationella prov skulle ge ett säkrare svar angående diagnosens tillförlitlighet.Diagnosens förmåga att förutsäga elevernas betyg i första matematikkursen i gymnasiet var god. Sambandet mellan diagnos och gymnasiebetyg var starkare än sambandet mellan diagnos och grundskolebetyg. Detta kan ha flera orsaker: (i) gymnasielärarna som konstruerat diagnosen har endast tagit med uppgifter som sammanfaller med första? gymnasiekursen, (ii) grundskolor sätter betyg på olika grunder, (iii) elevernas matematikkunskaper förändras över sommarlovet..

This master thesis is the documented work of the construction process and testing of a three hour laboratory session in mathematics aimed at high school level students. The purpose of the thesis was to create an interesting laboratory session for the science education center ?The House of Science? that could be used as a part of their regular program directed to schools. The thesis explores the possibilities for how one can construct a laboratory session on the topic ?molecular symmetry? as well as the underlying pedagogical theories used to describe learning processes in creative contexts.

In health care today at Uppsala County Council the daily work involves spending time at the computer. IT-systems were implemented to support and aid the care givers in their work. Around these systems there is a support organization to support the users in using the system. The aim of this thesis is to investigate this organization in terms of how well it works and how successful it is in helping the users. This has been done by investigating the flow of information trough the organization and by focusing at the role of IT-coordinators with responsibility for support, process development, education and statistics.
