Does a person´s self esteem contribute in the process of creating false memories? Previous studies show that mood is related to false memories as well as to self esteem. This led to the focus of this study, to examine the relationship between false memory and self esteem. The question is examined by comparing the amount of false memories produced in the Deese-Roediger-McDermott (DRM) procedure with people´s scores on Rosenberg´s self-esteem scale. 59 people participated in a test with three different elements, a self esteem test and a memory test with both recollection and free recall.

The aim of this study is to examine the patient's understanding of the counselling while testing for an STI. The method was an inquiry directed to patients at two receptions, where tests for STI are made, and on the Internet for patients who made a test within the last year. The study involves 95 participants, 39 answered the inquiry directly after the test. The main results show that most participants are positive to talk about their sexuality and sexual strategies with the personnel, irrespective of who takes the initiative to the counselling. Women are yet more negative then men to talk about their sexuality, even if the test is made voluntarily by the woman.

This essay examines if formative assessment causes any impact on upper secondary school students results in social science. Other questions asked are which group of students benefits most from formative assessment and if any connections can be found between the students result and their cognitive approach to learning, problem solving capability and attitude to school.Two classes from a school in Stockholm were chosen to participate in the study. The theoretical framework is mostly based on former research performed by Black and William (1998, 2003). Multiple methods were used, including an experiment with a parallel-group design with two groups, a survey and a problem solving test. Statistics is used to describe and analyze collected data.Both groups were taught during five lessons in the same field of knowledge with the same kind of teaching, apart from formative assessment.

This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.

Industrialization of construction is by some considered to be a solution to the building industry's problems about the lack of quality, high production costs, low productivity and poor environmental adaptation. Meanwhile, industrialized construction partly earned a bad reputation after the million housing program. As large-scale projects where promoted during this period, it worked very well to use the technique of construction elements. In the mid seventies though, criticism arose which claimed that the aesthetic qualities had been deprived in the corporates effort to make housing production as efficient as possible.Tyréns, Derome and CBBT (centre for building and housing in wood) cooperates in a development project to develop a building system for 4-8-storey buildings, consisting of three platforms: a technology platform, an IT platform and a processing platform. The technology platform consists of flexible, industrially built flat modules of wood and from this platform the subsystem stairwells, is broken out.

Studien avser att studera effekterna av arbetsplatsförlagd fysisk träning 2 x 60 minuter/vecka i 7 veckor hos personer med stillasittande arbete påVO2max, rörlighet, uthållighetsstyrka och kroppssammansättning. Vi använder oss av en kvantitativ metod som består av datainsamling genom tester före och efter träningsperioden för både interventionsgruppen (n=25) och kontrollgruppen (n=11). Resultaten visar på signifikanta skillnader hos interventionsgruppen på variablerna VO2max (p=0), visceralt fett (p=0,001), fettmassa (p=0,001), vikt (p=0.006), Body Mass Index, BMI (p=0,005), uthållighetsstyrka enligt Sörensens isometriska uthållighetstest (SIU) (p=0) och Trunk Curl Static Endurance test (TCST) (p=0,045), rörlighet i halsrygg (p=0,010) och rörlighet i hamstringsmuskulatur via Sit and reach test (p=0).  Inga skillnader ses i blodtryck och, skelettmuskelmassa i armar, bål och ben. Inga signifikanta skillnader ses hos kontrollgruppen oavsett variabel. Slutsatser av studien är att man kan se effekter genom denna typ av intervention på flera olika variabler och förslag till framtida forskning är att försöka utesluta samverkan av andra faktorer för att ge en mer exakt bild av den fysiska träningens effekter på arbetsplatsförlagd träning..

The incineration of waste is steadily increasing in Sweden and so is the production of ashes. The bottom ash has for many years been used as construction material in landfills. Now many of the nation's landfills are closed and there is a great need to find another beneficial use for the ash. Bottom ash is a gravel-like material and with its material properties it can replace natural gravel in parts of roads and surface constructions. Today this use is only approved within landfill areas where leachate is collected and checked.

Construction of Identity and Charismatic Leaders deals with fundamentalism and Islamism within the United States, emphasising on similarities between fundamentalists and Islamists. The term "fundamentalist" is here referring to Christian extremists, while "Islamist" refers to the Muslim counterpart. The purpose of the essay is to make North American fundamentalism and Islamism comprehendible on a larger scale.In order to show similarities between these groups when it comes to values, structure and commitment to their tasks, it is important to understand the nature of the religious devotion.Analyzing the similarities of the two groups enables construction of general criteria for how anthropology of religious extremists can be outlined..

Purpose: In order to curb the prevalence of undeclared work and to improve competi-tion within the building and construction business, reversed charge audit will from July 1, 2007 onwards be applied within the building sector. The new rules entail a consider-able amount of delimiting problems as regards both businesses and services.The aim of this essay is to study the rules as well as direct the light upon various consequen-tial delimiting problems. Furthermore, we will investigate what the effects are on the busi-nesses, as well as their view regarding this. Apart from this, we will also investigate who will benefit and who will be disfavourably affected, respectively, by the new lawMethod: The investigation has been conducted with a combination of qualitative and quantitative methods. Firstly, an opinion poll was carried out, directed towards Swedish construction companies, and this was then deepened using three interviews.Result & Conclusions: The essay demonstrates that the new rules have entailed more work to a varying degree for the companies.

 The purpose with this thesis was to develop a designguideline which will simplify the development of new products that will be laser welded. The need for this thesis has come forward from the quality problems that Volvo Construction Equipment, Components Division is having with their laser welding manufacturing unit. The reason for the problems emerges from the bad communication between the development unit and the manufacturing unit within the company when the products produced today was developed. This resulted in products that were hard to and in some cases almost impossible to weld. To avoid these problems from occurring again it was needed to gather the experiences within this area and compile it and present in a brief a pedagogical manner. The information for the groundwork of our results has been gathered by interviews of several key persons in Volvo Construction Equipment, Components Division.

This report deals with hard surfaces and the factors which are behind the criteria for dimensioning, also dependent on the level, or volume, of traffic. A test was made on slabs of two kinds of natural stone. This was made to see if the values that were reached for breakload was transferable to the same tables that the concrete industry is using for surface dimensions of slabs and paving stones. The test showed very high values and the result, together with the written study, led to the author?s suggestion for a classification table where slabs of natural stone were divided in to different classes depending on traffic, thickness and durability..

This essay is a qualitative study concerned with questions about disability. I set out from a definition of disability which highlights non-disabled peoples´ participation in making a disabled person ?the Other?. My aim is to contribute to an understanding of the experiences of disabled people as well as problemize the way that normality and disability is socially constructed. The empirical material of the essay consists of qualitative interviews with disabled men and women and the essay is written with a critical perspective.

THE THIN RED LINE ? Identity in theory and method With this essay I want to explore some possibilities with the term identity within archaeology. Identity is a term best understood in the light of different scientific approaches. For instance the anthropological and historical angel combined with the quality of archaeology, as is the case in this essay. By combining these approaches, I create a (clarification) method of exploring traces of identity.By analysing two different graves from Scania, having a negligible number of artefacts from the Viking Age, and three graves from Bornholm, known for its large number of finds from this period, I test the ability of my method.
