The city?s public environments are meant to be perceived as safe and inviting areas to visit any time of the day. In recent decades the number of vandalism complaints has doubled and graffiti has become so common that it received a separate category in the crime statistics. With this type of impacts in the public environments the experience are precarious and a boring sight. It?s difficult to put a price tag on these types of crimes, the number of unreported cases suspected to be large.

The study seeks to show to what extent there are differences between the groups? phonological awareness.

Background and problem: In the last few years the threat against the environment and especially the emissions of carbon dioxide has become increasingly debated. The government have set up a goal to lower the emissions of carbon dioxide with 40 percent until 2020 compared to the level in 1990. The emissions in the transportation sector have, in contrast to the total emissions, increased since 1990 and will continue to increase unless powerful control measures are implemented. The lorry centres have to use strategies to answer to these external threats which lead us to the two questions of this thesis: - What methods do the lorry centres use actively and which do they consider as the most important methods for fuel saving? - Are there any differences which methods small, medium and large centres considers as important? Purpose: The main purpose of this thesis is to examine which methods lorry centres use actively and which they consider as important for fuel saving.

There are several methods and models within the areas of software engineering on how to proceed during a software development process. For each of these methods and models there are benefits and drawbacks, depending on how you choose to look at them. A difference of principle between the different models is that they either advocate iterative development or not. In parts of software engineering one makes use of different methods depending on which is most fitting in a specific situation. There are several methods on how to recieve more qualitative data from the end-users during the requirement collection, but the reappearing pattern is still user centric participation, which means that the user participates more actively in part of or the entire development process.

The use of earth bricks in Scanian building traditionThe present work is concerned with the manufacturing and use of earth bricks inbuilt heritage in the south Swedish province of Scania. The first part of the studyprovides a thorough description of the traditional use and manufacturing of earthbricks based on relevant literature, archive material as well as interviews withinformants. This forms a basis for the second part of the study in which practicalexperiments on and tests with earth bricks where carried out. This involved themaking of traditional earth bricks of different composition. The new handmadebricks were compared with industrially produced bricks (extrusion bricks) and oldhandmade bricks.

This is a qualitative study that explores how bilingual children develop their language through play. The study is based on observations and interviews conducted in a preschool located in a multicultural area of Stockholm.The purpose of using two qualitative methods; observations and interviews, was to get a bigger picture of the study area. The results of the study, illustrated through observations and interviews that I have conducted, shows that the game has great role for bilingual children's language development. Furthermore, the results show that the informants are aware of the importance of play for bilingual children's language development especially when they are talking about investing in the promotion of children's language by using different methods and materials in their pre activity for various games and activities.One of my conclusions is that bilingual children learn the language during both free play and structured play especially when educators are present and aware of the activities that they perform. It is also important to see children as individuals to cover all the needs of children at different activities.

The main purpose of this essay is to examine, in what way the paintings by Karin Broosand Markus Åkesson are images of autentic situations and furthermore in what way themediespecific essence is performed photografically. Questions occuring: 1) How are thecreations of reality shaped in the two chosen photorealistical paintings? 2) In what waycan you distinguish the iconicity and indexicality in the paintings Den vita klänningenand The Passage? 3) How does the photografic presence occur in the paintings andfuthermore how can you distinguish the mentioned parts above according to thepaintings? The theoretical standpoint is based upon Charles Sanders Peirces ideasconcerning iconicity and indexicality. The methods used are based on thoughtspresented by Andrew Benjamin and Mieke Bal. The signs of iconicity and indexicalitycan be studied in various ways in the two paintings, depending on how abstract andobvious different parts occur in the paintings.

Today, pigs are moved on farm, between farms, between countries and to abattoirs. This movement of live pigs requires handling practices that are designed for the purpose. The objective of this study was to research the use of paddle in moving pigs, to investigate if there were different methods of paddle practice, explore the time efficiency of different kinds of paddle use and if there were any time variations in methods that varied in intensity of touch. This study was done on two Swedish abattoirs for a total of five weeks. A total of 22 transporters working at two different abattoirs where studied during unloading of pigs at the abattoirs.

Stockholms läns landsting bedriver ett kvalitetssäkringsprojekt, Qualitative Assessment of Psychotherapy in Sweden (QAPS). Denna uppsats syfte var att undersöka patienters upplevelser av att delta i QAPS. Det har bara gjorts ett fåtal liknande undersökningar tidigare. Psykoterapiutvärderingar har visat sig ha positiva bieffekter för deltagande patienter. Denna undersökning genomfördes med både enkäter och intervjuer.

Background: Funds have become a more popular way for investments. After the financial crisis in 2008 there was some sectors that shown a better results than other depending if the sector was affected by the economic situation or not. Therefore can  investments in sector funds be a good way to get a high return, but it also has a high risk.Problem: Has the risk any impact on the return considered funds in sectors that is affected by the economic situation relatively to sectors that isn?t affected by the situation in the economy?Purpose: Determine whether sector funds risk has any impact on the return. Also if there are any differences between sectors depending if they are affected by the economic situation or not.

This master thesis aims to examine the methods of the conservation field and their visionabout maintenance and change, in terms of liturgical values. This is to be able todetermine if there is a need to develop the methods that the field of conservation has tosafeguard the intangible cultural heritage of the churches.This is mainly a literature review, focusing on different tutorials from the Swedish nationalheritage board, and different texts on liturgy aswell as Unesco's Convention for theSafeguarding of intagible Heritage (2003), ratified in Sweden in January 2011. A casestudy of the practical work has been carried out on three churches that have undergonechange. The application process and the results were important for this study.The conclusion is that the conservation field have ambitions to preserve the liturgicalvalues, but they do not have sufficiently developed methods to do so. Nevertheless, itappears that most cases of change in churches, increases the liturgical values..

The aim of this thesis was to investigate if the robotized welding method FSW (Friction Stir Welding) could be applied for joining a rotating structure in an aero engine at Volvo Aero Corporation. FSW is expected to introduce less defects than today?s welding methods and could therefore be suitable for critical aero components. The material is the nickel based alloy Inconel 718, however a material experimentation is outside the scope of this report.The main goal of this study is to verify if the ESAB ROSIO robot based FSW-system has a suitable work space to be able to weld the rotating structure, and if the welding tool has accessibility to the joints. The FSW-process needs a rigid fixture, and a number of fix-ture concepts are presented based on a proposed weld sequence.

The aim of this thesis was to answer a number of questions about the environmental consequences of aircraft de-icing. A further aim was to suggest how the environmental consequences due to the release of de-icing fluids can be measured and reduced.The main impact of the aircraft de-icing on the environment is due to the large oxygen demand for the degradation of glycol based de-icing fluids which are released in the environment. The effect of the increase in oxygen demand depends on where the degradation occurs in the ecosystem. In a sensitive ecosystem, the large demand of oxygen could provide an anaerobic environment which would be harmful for many types of organisms.In order to reduce the negative effects of the applied de-icing fluid, there is some type of collection system at every regular airport in Sweden. The methods of collection can be divided into two general groups, hydrological isolation or vacuum sweeper trucks.

The technology used in the development of web-applications is evolving at such rate that it has become more and more important to keep web-applications modern. If an application is based on a technical platform that is not renewed, the platform may over time develop into an obstacle in further development of the application. There may be compatibility issues and some of the code may be unnecessary due to abstraction, and therefore more time consuming to work with. Sometimes the reason may be that an application has been built to run, and is running on an application server that is no longer being maintained. The system can be large and modernization can cost a lot.
