Femåringar berättar på svenska och engelska : Referensdata och jämförelse med 6- och 7-åringar

År 2009 startades det europeiska forskningsprojektet COST Action IS0804 med syfte att få mer kunskap om flerspråkiga barns språkutveckling och utveckla bedömningsmaterial anpassade för flerspråkiga barn. Inom COST Action fokuserar arbetsgruppen Narrative and discourse på berättelser (narrativer) som ett sätt att bedöma språk hos barn. Berättande liknar naturlig språkanvändning och anses ge en mer rättvisande bild av flerspråkiga barns förmåga än andra logopediska test. Av narrativgruppen utvecklades bedömningsmaterialet MAIN (Multilingual Assessment Instrument for Narratives). Med MAIN kan barns produktion och förståelse av berättelser undersökas på makrostrukturell nivå.

Internalisation of emissions costs from Swedish aviation

This thesis examines the emissions costs of Swedish aviation and their degree of internalisation under current economic instruments. The results show that the degree of internalisation spans from practically zero for a long-haul flight to 6 per cent for a typical domestic flight, where the climate cost, including high-altitude impact, makes up the main part of the cost. To inform evaluation of the consequences of this underinternalisation, or attempts to correct for it using price instruments, the price and income elasticities of international leisure air travel from Sweden are estimated using household expenditure data and two different price measures. The resulting elasticities are very high ? 2.03 or 2.04 for the income elasticity and -2.53 or -1.88 for the price elasticity ? and should be interpreted cautiously due to data limitations, especially for the price elasticities.

Metodik för utmattningsberäkning av svets i vibrationsmiljö

In this work, a method was developed and evaluated for calculating the life of welds under the influence of fatigue loads from a vibration environment. Typically, a shaker table is used for testing a component against vibration loads. The shaker table creates a vibration environment that is defined in the frequency domain by a power spectrum.Similarly, a virtual vibration table can be used to calculate the same type of load environment, which can then be used to calculate the expected lifetime. The benefit of this method is that it can be used in design, as well as in simulation of tests before physical verification tests are carried out.Today there are methods for calculating fatigue life of non-welded base material, but since many components contain welded joints, there is a need to apply this method to those types as well. To achieve this, the thesis combines two different areas, which together provide a method for fatigue assessment of welds using a virtual shaker table.The methodology is carried out by modeling the component, and its welded joints, in a finite element program.

Parkplan för Kungälv med förutsättningar för sociala värden :

To work with environments outdoors for people, animals and plants is the main topic for the landscapearchitect. On several occasions the work is about public places that is to be in relation with other parts of the town. It is about the activities and the life that take place. The physical environment and the interpretation of it gives possibilities or obstructions for people who moves around or spend time in it.Since public places, parks and places for movement are used in daily life they strongly effect the people who use the places. The concequences of this effect can be positive or negative experiences.A positive example is a passage over a brook on the way to school while a negative one is to be afraid while passing a tunnel when it is dark outside. Other examples of concequences are stress effect from traffic noice or calming environments with twitter of birds. The physical environment is also a part of the total interpretation of a town.

Att leva sitt liv: Tonårsflickor om livsangelägenheter, informationsbehov och informationsanskaffning.

Adolescence is a turbulent time in life and gives rise to new information needs for young people. Information needs related to school subjects have been relatively well researched but few studies have focused on information needs and use related to life concerns. The purpose of this Master's thesis is to examine the information needs of a number of teenage girls in relation to their life concerns and how they meet these needs. The sample consists of twenty-one girls aged thirteen and fourteen. The research is based on literature studies and qualitative interviews combined with a questionnaire.

Kväveförluster och energianvändning på mjölkgårdar i västra Sverige :

Protecting the environment has with time grown to take a more central role in the society. Agriculture plays an important role in the society since this sector produces our food. More thorough research on how agriculture affects the environment is therefore motivated. This research can be used to improve the agricultural practice from an environmental point of view. This is something that both the farmers and the consumers can profit from. This study aims to form the basis for creating environmental indicators for use of nitrogen and energy on dairy farms. Twenty-three farmers in western Sweden have been interviewed about their farms, both organic and conventional. They produce milk with different intensity, defined as the amount of milk delivered (sold) per hectare of arable land.

Förröjning i förstagalling - vad kostar det och följer utförarna instruktionerna?

This report is a B.Sc. Forestry thesis work at the school for Forest Management, SLU. The work was an assignment from the forest owners? association Mellanskog. The aim of the work where to investigate the economical result of removing undergrowth trees before first thinning, and a follow-up of the contractors and their compliance with Mellanskog standards. This thesis work was divided in three parts: The first was to find a relation between the net volume from the first thinning and the cost of cleaning undergrowth trees. Secondly there was a follow-up in the field, to investigate whether the contractors have done the undergrowth cleaning according to Mellanskog?s directives.

Balans i arbetet, balans i livet : En kvantitativ studie om arbetslivets inverkan på privatlivet

This study focuses on work related factors which have an effect on the balance between peoples work and private/social life. Commonly discussed in the daily debate is the so called ?livspusslet?, the time puzzle. The question is: How do you balance the demands from work, family and society? A lot of peoples health and family relations suffers from a stressful situation at work.It?s not hard to figure out that the possible factors which could have an effect on the balance between peoples work and private/social life are many.

Föräldraledighet som en kompetensutvecklande period i livet

The aim of the study was to examine whether parental leave can serve as capacitating period in life. More specifically our aim was to get a deeper comprehension of the abilities and competencies developed through parental leave and how these can be of use to the individual when at work. 12 semistructured interviews were conducted with employees from a large organization in the south of Sweden. The results were analyzed using a hermeneutic approach. The results of the study show that competencies and abilities such as effectiveness, organizing, multitasking, leader abilities, communication, sensitivity, limiting skills, mindfulness, acceptance, self-confidence and life balance were enhanced during parental leave.

Vilka effekter har lojalitetsprogram på kundlojalitet? : En studie om frequent flyer-program och deras effekt på kunderna

The arm?s length principle has existed in Swedish law since 1928 but has previously been given little attention. In 2007, documentation requirements were introduced, and the government began to do tax audits regarding transfer pricing. This thesis examines how the documentation requirements and tax audits affect the application of the arm's length principle. The research consists of nine interviews with a total of ten people at the tax authority (Skatteverket) and audit- and consulting agencies. The results of the interviews are analyzed using the agency theory. Many companies are risk averse and prefer having correct transfer pricing instead of taking on challenging strategies that can be risky in case of an investigation by Skatteverket.

Förändrad aptering av massaved från 3- till 4-meterslängder vid gallring inom Södra : en systemanalys av effekter från avverkning till levererad virkesråvara

The costs of logging and of transportation with truck are dominating the total cost of wood delivered at industry. To support the profitability for the members' forestry the processing and handling with the timber has to be as efficient as possible. Increased length of pulpwood in thinning is one conduct that can result in higher productivity and/or lower costs. The study is scaled as a system analysis with the aim to exemplify the differences between working with 3- and 4-meter as standard length of pulpwood, related to biological aspects, timber receipts, cost of logging and cost of transportation with truck. Important aspects are if the change is technically and biologically feasible and economically profitable.

TaqMan® Sample-to-SNP Kit? : evaluation of kit for low-cost and fast preparing of DNA-samples before genotype analysis

 Genotyping can be used to link genetic variation among individuals to certain diseases or conditions. Some known disorders and states that are dependent on single nucleotide polymorphism (SNPs) are lactose intolerance, venous thrombosis, hereditary hemochromatosis and the difference in sensibility among people to metabolise drugs.In this project a new kit, TaqManÒ Sample-to-SNP KitÔ for extraction of DNA and preparation of the extract for genotyping with real-time PCR and allelic discrimination, was evaluated. QIAamp® DNA Blood Biorobot® MDx Kit was used as the reference method.The purpose of the comparison was to find a method that makes DNA extraction from blood samples cheaper and faster, but with the same reliability as the reference procedure.The results of the evaluation showed a complete agreement of the genotype results between the methods tested, which means that the new method was as reliable as the reference method. The costs of reagents and material would be reduced with 52% if the new method is adopted, that alone would result in a cost reduction of 144 000SEK a year with a sample volume of 650 samples/month. The time for DNA extraction would also be reduced with the new procedure. .

Betydelse av laborativ matematik i dagens skola

The goal of this study is to gain knowledge and understanding of how a teacher can apply mathematics with assistance from practical mathematics. Students? point of view on mathematics within practical mathematic lessons will also be examined. Four teachers from preschool to third grade in primary school were interviewed. 30 students from grades one to three were also surveyed. The study shows that teachers see a major benefit when practical mathematics is used in the theoretical teachings of mathematics.

Ylva Oglands socialrealism : Att göra det osynliga synligt

The purpose of this paper is to analyse how work by Swedish artist Ylva Ogland (born in 1974) function as an eye-opener for the social marginalisation of people identified with homosexuality, prostitution and drug addiction. Although highly present in reality, these phenomena were historically, and are still today, hidden from view in public discourse. I have focused on the installations Rapture and Silence and Things Seen, and the still-life painting called Xenia. I argue that these artworks carefully represent the above-mentioned marginalised groups, by way of references to comparable motives in the history of art, from neoclassicism in France, to realism and romanticism..

Optimering av B-stolpe

Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.
