Mobiltelefonen som social artefakt inom familjen : en studie med föräldrarna i fokus

Studies of modern communication media such as Cell Phones and so called Instant Messengers are popular today. This study focused on these modern techniques, focused on parents as a target group and on what is important for them in everyday communication.By exploratory using three focus groups it became clear that the children, and the link to them was the absolute most important thing for the parents. It became clear that this link to a great extent today exists through the mobile phone.In a following study a Mobile Instant Messenger called My Friends was introduced. It was used by two families during two weeks to see how it would change the communication within the family. The focus was to see how problems with availability were handled, it turned out that:My friends had a more obvious way of indicating availability than the Cell Phone had.

Studie av två jetströmsstråk associerade med kraftig flygturbulens

Jetströmmar betyder mycket för meteorologer och fungerar som ett hjälpmedel för prognostisering av lågtryck. Kvadrantmodellen för jetströmsstråk beskriver hur det kan bildas lågtryck och konvergens vid marknivå på olika sidor om jetströmmen. Jetströmmar är också av betydelse för flygtrafiken, eftersom man kan spara tid och bränsle genom att flyga in i ? eller genom att inte flyga in i ? en jetström. Det är känt att jetströmmar ibland kan ge upphov till klarluftsturbulens (CAT), och studier har visat att turbulensen ofta är associerade med stabilt stratifierade zoner i närheten av jetströmmen.Denna studie börjar med en teoridel där jetströmmars uppkomst och kvadrantmodellen redogörs.

Kvävestatus och risk för nitrifikation i två avverkade skogsområden i Halland

Nitrogen deposition leads to environmental damage in areas where the nitrogen deposition is high. Southwest Sweden receives an annual nitrogen deposition of up to 20 kg N/ha. Nitrogen that is not assimilated by the vegetation is accumulated in the soil, which may lead to nitrogen saturation and an elevated risk of nitrogen leaching. Nitrogen leaching from forest areas in southern Sweden has proven to be higher than from agricultural areas, which have been thought to be the main contributors to elevated nitrogen levels in rivers and lakes. The amount of nitrogen that leaches depends on the fraction of the total nitrogen in the soil that consists of nitrate, since nitrate is easily transported through the soil.

As all of PC´s customer enquiries are unique and must be considered an individual project, PC continuously works in projects. An analysis of the project flow was conducted based on interviews at and visits to PC as well as relevant documents distributed by the department. The report gives an understanding and analysis of how PC works in projects.

"Varför blev det så här?" : om utemiljön på Herrgården från 60-talet och framåt

The residential yard at Kvarteret Landsfiskalen 1, in the area Herrgården in Rosengård, Malmö was built in 1971 and has since then been reconstructed twice, in 1984 and 2008. The yard is found in an area which was built during the years 1965 ? 1974, a period in which the swedish goverment approved a decision to build one million homes, and much of the events in this particular yard is also typical for the process in many other areas built during the same period.At the original construction the design of the yard was entirely incused by the pressure in time and finance, one was under at that time, in order to over- come the housing shortage. The design it has nevertheless been given, reflects the esthetic ideals of that time well.The building of the area was barely finished when the swedish authori- ties started handing out grants in order to support the rearmament of the outdoor environment in the areas built during the so called ?million program?.

Tal, text, handling. En undersökning av viljor och hur dessa uttrycks i handling i Tjechovs Tre systrar

In this essay I have examined text, speech and action in Chekhov's Three sisters, as well as how the characters express their wills in action and in speech. I have used different methods such as action analysis, the five W questions and BSI (background, situation and intention). These methods are similar to those actors use to uncover situatedness of characters and to find motivated and intentional patterns behind their actions.I have used these techniques to identify the plot, explore what happened before the plot begins and to read the text in terms of action. The aim was also to find the counter points where wills expressed in action are contradicted by wills expressed in speech. Using these methods I found that the characters in Three sisters manage their lives dreaming about the future or recalling the past, except the character Natasha.

Media och dess inverkan : exponering av idealiserade könsroller och dess inverkan på unga människor

The purpose of this study is to examine the impact that idealised body images found in media have on the body-image and wellbeing of young men and women. The study was carried out using questionnaires based on the BAQ and HAD scales to examine the participants' views of themselves as well as symptoms of anxiety and depression. Time spent by the participants using different kinds of media, as well as their degree of social support, was used with the purpose of examining relations and differences in body-image between men and women. The questionnaire contained advertising images to examine whether short time exposure had any impact on the participants. In order to determine this, one half of the questionnaires contained idealised body-images, whilst the other half contained images without human objects.

Betydelsen av skogens ålder och förekomst av lavar för renars val av vinterbetesområde :

This is a study on winter groups, ?siida?, of semi-domesticated mountain-migrating reindeers that move to lichen pastures in the lowland boreal forests during winter. The aim of the study was to determine reindeer habitat use in their winter ranges in a managed forest landscape. The reindeers use of three different types of forests was determined, 1) 100-130 year old, 2) 20-40 year old forest and 3) clear-cut areas. All sites were dominated by Scots pine, Pinus sylvestris, and had the same types of ground vegetation.

CFD simulering av en fyrtakts Otto motorcykel motor

This thesis deals with the numerical 3D simulation of a four stroke, spark-ignited, internalcombustion engine, which is mounted on a high performance motorcycle. The work, carried outin collaboration with Politecnico di Milano and MV Agusta, focuses on the simulation of theintake, compression and expansion stroke, including combustion simulation, using an opensource CFD code.Simulation of internal combustion engines offers a great challenge in the field of CFD research.Moving boundaries of the solution domain, caused by the motion of the piston and valves, leadsto deformation of the computational grid, with decreasing quality of the solution as result. Basedon this, a previously developed mesh motion strategy was employed where a number of meshesare used to cover the whole simulation cycle. Within each mesh interval the internal cell pointsof the mesh are moved to account for the boundary motion of the piston and valves. This strategywas previously applied to simplified geometries as well as real engine geometries.

Nationella stereotyper i reklam

AbstractBackground: Countries can be seen as brands (nation brands) with brand values that transmitto the country?s products. Country-of-origin (COO), the brands nationality, links the productto an associative network of cultural shared national stereotypes. Through associating thebrand with a country or a region, the credibility of the brand can increase and strengthen thebrand. Therefore COO is used in marketing to position a brand.Purpose: The purpose of this study is to examine how luxury fashion brands communicatetheir national identity through analyzing their advertising.

Kommunikationseffektivitet och kommunikationsstrategier för L1- och L2-talare i referentiella problemlösningsuppgifter

This thesis examines and measures differences in effciency between L1- and L2 language use for solving referential problems. Quantitative measures used in the study were time and error frequency. Qualitative measures, such as how the tasks and the participants own performance were experienced, were measured by an post interview and two questionaires. Two different tasks, a sorting task and a construction task, in which each informant was given the role as a constructor or instructor, were used for data gathering. A total of 20 dyads, divided in two language groups (English and Swedish) participated in the study.

Etisk organisationskulturs inverkan på revisionskvalitet i företag

In today's society there is tougher climate both financially and time wise. Accountants working under tight deadlines leading to the compromise between quality and quantity in the audit process and them therefor are being guilty of so-called reduced audit quality, RAQ. Reduced audit quality involves intentional actions designed to somehow reduce the evidence contained in the audit. We examine in this study the impact of time budget pressure (TBP), underreporting of time (URT), ethical organizational culture and charismatic leadership has on the frequency of RAQ.Previous research has already shown that there are clear links between TBP and RAQ, between URT and RAQ and between ethical culture in organizations and audit quality available. Five hypotheses were designed to the study.

Sarbanes-Oxley Act sektion 404 om intern kontroll och dess konsekvenser

AimThe purpose of this study has been to examine attitudes towards dance in a broad sense, among Swedish schoolchildren. The study has been done with three different questions in mind: What do pupils think and express about dance? Are there any differences in attitude towards dance between girls and boys? And how do the pupils relate to gender conceptions in connection to dance illustrations?MethodEight pupils 12 ? 14 years of age have been interviewed separately during physical education lessons. During parts of the interviews dance illustrations were used in order to encourage the pupils in their discussions, especially when asked to relate to dance and gender conceptions. The statements have been interpreted from a gender theoretical perspective.ResultsMy interview study shows that male pupils to a larger extent than female pupils inhabit hostile feelings towards dance as part of physical education lessons.

Optisk undersökning av dieselsprayer från en höghastighetsroterande insprutare

There have been changes in Earth?s climate system on both global and regional scale since the pre-industrial era and some of these changes are due to human activities such as the combustion of fossil fuels. This calls for the development of engines with a higher efficiency and less harmful emissions. One interesting concept is the Homogeneous Charge Compression Ignition (HCCI) engine, which has the advantages of potentially low emissions combined with high efficiency. However, HCCI with diesel fuel requires a relatively long fuel/air mixing time to ensure a "homogenous" charge.
