Detta är ett arbete som visar utvecklingen hos lärare i ett arbetslag som under två terminer har arbetet med temaenheter i NTA-projektet. NTA, Naturvetenskap och Teknik för Alla, är ett projekt som skall locka elever till ett naturvetenskapligt in-tresse. I projektet finns handledning till läraren och all materiel som behövs för arbete under tio veckor med en temaenhet. Syftet med arbetet är att undersöka vilka förändringar som sker inom ett arbetslag när ett nytt koncept tas in i den naturvetenskapliga undervisning. Tidigare forskning visar att framtidens lärare måste vara flexibla och kunna planera undervisningen efter en målstyrd läroplan.

The Swedish State Road Administration has since 1992 procured operations and maintenance of state roads on the open market. The procurement has been termed ?Grundpaket Drift?, GPD, and comprises mostly operational measures for road networks.The clients of GPD, SRA regions, have gradually changed the original documentation in order to adapt it to local conditions. This process has gradually led to that some parts of the documentation are creating problems for contractors interested in procuring jobs.This thesis tries to analyze GPD and clarify the differences that may be essential to the procurement process and to facilitate future joint working projects and processing descriptions..

This report evaluates whether normal approximation or resampling is to prefer for estimating the distribution of the sample mean and functions of the sample mean. The evaluation relies on simulation studies. The observations of the sample are allowed to be differently distributed. In the case of sample means they are also allowed to be dependent.For sample means the two approximations behaves very similar. The most important component whether we have a good or a bad approximation is how good the approximations catch the variance of the true distribution.

The public sector is a major purchaser of goods and services. By setting requirements for environmental and social considerations in public procurement, an authority has the possibility to use consumer power to influence the actors in a market. The purpose of this paper is to investigate public procurement of textile products in a municipality, in order to gain knowledge about factors that may be important for the use of environmental and social criteria. Håkan Hydén´s (professor in sociology of law) norm model was used as the basis of the analysis, where the conduct was investigated along three dimensions of the norm ? willingness, knowledge and system conditions ? in order to identify underlying factors that can influence the process.The results ? analyzed by using interviews and documents ? show that the procurer's willingness, motivation and knowledge are important factors in this context, as well as the political priority of the municipality.

This essay describes the philosophy of science that Thomas Kuhn puts forth in his work The Structure of Scientific Revolutions. The question is, does his description of the scientific paradigm work as well today as in the examples he gave in the book?The conclusion is that there are certain factors that make for a number of differences between science today and, for example in the seventeenth century. There is also a growing theory or vision of a post normal science laid developed by among others Jerome Ravetz. This theory or vision is an idea of a science close to peer-communities and fast as well as critical decisions involving opposite values..

The purpose of this report is to investigate teachers views of whether pupils with Asperger Syndrome, autistic symptoms or ADHD shall go in ordinary classes or special groups. The study tells you about what difficulties these pupils often have, what adjustments they need in their schoolsituation and the positive and negative effects of joining a special group.A teacher for special needs, two teachers in special groups and two teachers in ordinary classes have been intervjued and earlier made researches have been studied.The conclusions of this study are that the decision of whether a pupil shall go in a normal class or a special group must be made individually. Most pupils who are capable to profit from the training in a normal class and pass their examination, shall go in a normal class. The greater part of the recommended adjustments are possible to do in a normal class. But it requires more resourses and teachers with better knowledges about theese handicaps..

It is always more demanding and the risk for misunderstanding increases when communicating in noisy environments. The confusions and the mistakes that occur when speech is disturbed are very interesting and happens constantly. The purpose of this study was to examine speech recognition results from the test PB S/N +4 and find out which confusions that are made by the normal hearing and by the hearing impaired persons in the speech lists 3 and 4, and also analyse the mistakes from a phonetic perspective. Ten normal hearing and 50 persons with impaired hearing participated in the study. The people with impaired hearing were divided into two groups; DTMV 40 dB HL.The results were compared between the normal hearing and those with impaired hearing.

Utbetalningsbelopp för skadeersättning studeras. Datamaterialet uppvisar skevheter och 'tjocka svansar' vilket motiverar att modellera med en mer flexibel fördelning än normalfördelning. I detta arbete undersöks om NIG (normal invers gaussisk) fördelning passar för det..

En graviditet och förlossning är i de allra flesta fall en normal livshändelse. De senaste decennierna har andelen instrumentella- och kejsarsnittsförlossningar ökat på bekostnad av den normala förlossningen. Trots fler interventioner ses ingen skillnad i den maternella och perinatala morbiditeten och mortaliteten. I barnmorskans arbetsområde ingår att handlägga den normala graviditeten och förlossningen. Syftet med studien var att beskriva hur barnmorskan kan främja en normal förlossning.

Syftet med detta arbete har varit att ta reda på elevers kunskaper om de geometriska begreppen dm3 och m2 samt hur lärarna undervisar i dessa avsnitt. Detta har vi tagit fram genom att först göra en litteraturstudie följt av intervjuer. Av litteraturen fick vi fram att laborativt arbete och materiel är essentiella delar i geometriundervisningen och har så varit under hela skolans historia. Det gäller att använda materielen på rätt sätt för att få ett bra resultat.Resultatdelen, med intervjuer, visade att elevernas kunskaper gällande begreppen är vaga och ofullständiga. Deras resultat var sämre än vad vi trodde med undantag för de starka eleverna.

Bakgrund: Forskning har visat att förlossningsupplevelsen har betydelse för kvinnansframtida inställning till barnafödande. Forskningsresultat har huvudsakligen presenterats för normala graviditeter eller där urvalet varit blandat (normala och komplicerade graviditeter). Begränsad forskning finns om hur komplicerad graviditet kan påverka förlossningsupplevelsen.Syfte: Att jämföra förlossningsupplevelse bland kvinnor som haft normal graviditet respektive graviditetsdiabetes samt studera sambandsfaktorer för förlossningsupplevelsen.Metod: Studien är en retrospektiv kohortstudie där data insamlats med hjälp av enkäter. Deltagarna (n=444) är slumpmässigt valda bland kvinnor i Sverige med normal graviditet och kvinnor med graviditetsdiabetes. Kvinnor som fött tvillingar och som inte angivit barnetsfödelsevikt exkluderades från fördjupningsstudien, vilket innebar att data för 429 kvinnor, 326 med normal graviditet och 103 med graviditetsdiabetes ingick.

The principle of proportionality is considered one of the most important contemporary legal principles on which it intends to protect individual citizens against disproportionate action by the authorities. This aroused our interest prior to this study. The essay reveals how such behavior might look like and how courts have chosen to adjudicate in cases where the individual has been discriminated against or subjected to unreasonable demands in public procurement. That section of the law that were current throughout all court cases are Public Procurement Act (2007:1097) LOU. That which we have seen in every court case is that the applicant has not received a proper fair chance when the requirements of the contract often been asked in a way that either exclude the smaller applicant company or rule out various potential applicants parties due to excessive and sometimes unnecessary requirements.
