BNP och hushållsproduktion : En jämförande fallstudie av Sverige, Tyskland, Estland och Finland baserad på satelliträkenskaper för hushållsproduktion

This document presents calculations of adjusted GDP based on satellite household accounts for the year 2001 with the purpose to compare adjusted and official GDP for Sweden, Germany, Estonia and Finland. Household production in each country is estimated using time use survey data from Eurostat and a monetary value is estimated using average wage (after taxes) for each country. The results indicate that the value of household production using this methodology increases GDP with between 42% (Finland) and 55% (Germany) compared to official GDP statistics. A comparison of GDP/capita between the countries included in the study shows that the GDP/capita in Germany increases more that the other countries due to the relatively high proportion of time used for household production (mainly German women) combined with a high average wage. In fact, the results show that Germany has higher adjusted GDP/capita than both Finland and Sweden (but Germany has lower GDP per capita when official statistics is used for the comparison).

Grupperingar i en nysammansatt klass

The purpose of this paper is to try to get an understanding of the underlying causes and reasons that students starting in seventh grade junior high school seek out a particular group, and the extent to which they do so.The work is based on the questions: How do students perceive the meeting with their prospective bench-companion in a new composite class? What should a teacher consider when it comes to bench placement in a new composite class? Do the students change, and if so to what extent, friends when they start high school? What are the factors that affect/have affected the students' choice of friends? How large a role does the school play for pupils relationships? What thoughts and feelings do the students have regarding new encounters?I have conducted in-depth interviews with six adolescents in grade seven as the basis for the understanding of how students relate to group selection and group affiliation, and I have then compared this material with previous research on the subject. Furthermore I have availed myself of literature in social- and group psychology.The conclusion which has emerged is that the most important component of a group-process is the sense of solidarity and security, and the results show that students largely retain their old relationships rather than adding new, when they start high school. Hence the teacher plays an important role in ensuring that any imbalance in the group is offset and make sure that nobody is excluded, but also to help make room for new groups and be aware of the sensitive and responsive phase of life that the young people are in..

Stärkelsenedbrytningens betydelse för mjölkkors konsumtionsmönster och mjölkproduktion :

Feed intake in dairy cows is regulated by a variety of factors influencing hunger and satiety. One of the regulation systems includes the short chain fatty acids produced during feed degradation in the rumen. Starch can be digested either in the rumen where short chain fatty acids are produced or in the small intestine where glucose is the end product. Since glucose does not have the same effect on satiety that short chain fatty acids have, the site of starch digestion might be an important factor that affects feed intake and milk production. The aim of this study was to investigate the effects of site of starch digestion on feeding behaviour (feed intake, consumption time, and eating frequency) and milk production. Because feeding behaviour is closely connected to the cows? environment, the study also included observations of behaviour. Three different feed rations were compared.

Modell och analysverktyg för beräkningav frekvensförlopp

The power system modelled in this thesis work has been developed for simulationwhen e.g. the production in some part of the power system is changed. The powersystem has been modelled according to the swing mass of the system, the frequencydependency of the load and the turbine governor. The model determines the systemfrequency, the period of regulation and the power exchange between the differentsubsystems in the Nordic synchronized system.In this model the system frequency is assumed to be the same in all different parts ofthe power system and the voltage conditions in the power system are neglected. Forthat reason power swings does not occur between different subsystems in the powersystem, which usually occur as a result of the swinging connection between thetransmissions line.

Optimering av distorsionseffekt med hjälp av Fourieranalys

In music performers and music-making are oftenused different distortion effects to give the desiredcharacter on the individual sound sources andinstruments. These have different names (fuzz,distortion, overdrive) depending on the character. Tocarry out this work, an extensive literature study ofthe circuit diagrams of a large number of the classicdistortion circuits implemented. In this work, adistortion effect of the character fuzz was createdfrom several other existing effects. MeasurementsFFT, frequency response have been conducted tovalidate the desired results along the given problem.The finished effect was named Instant Carlos and aprototype was manufactured.

Att våga vara innovativ: En fallstudie om affärsutveckling av befintliga produkter i ett högteknologisk företag

High technology companies in Sweden spend a huge amount of money on research and product development in proportion to what they get back in earnings from their inventions. Product development has traditionally been regarded as much more important than business development. This thesis aims to point out the critical factors behind successful business development processes for high technology companies. We have chosen to make a case study of Hexagon, a highly successful and innovative company within the measurement technology business. Internal and external actors that are important for business development have been identified and interviewed in order to understand how ideas are developed and executed.

Kolbalansen vid olika skötselstrategier för skogen på Tagels fastighet.

Since the 19th century the concentration of CO2 in the atmosphere hasincreased by 40 percent as an effect of the use of fossil energy sources.Increased concentration of CO2 will likely lead to increased temperature,changes in precipitation, rising sea level and increased frequency of extremeweather like storm events. A step to reduce emissions of CO2 and mitigateclimate change, for the property of Tagel, can be to adopt new silviculturalstrategies and analyse which is the most effective. As a result of that, threescenarios was produced, business-as-usual (BAU), increased set aside landand energy. An introduction of windpower at Tagels estate (property) andeffects on carbon balance was also examined. By using the Heureka systemand LCA-analysis in this study, it showed that the scenario of increased setaside land was the most efficient way to reduce carbon dioxide (CO2)emissions for the analysed period of 100 years.

Motiv, möjligheter och framgångsfaktorer med RFID på lastbärare : Införande på Brunskoggruppen AB

Gapet mellan större och mindre lokala aktörer på transportmarknaden ökar vilket leder till krav på kostnadseffektiva och differentierade verksamheter. Detta bidrar i allt högre grad till effektivisering och automatisering av verk­samhetens processer. Ett problem för verksamheter i logistiska samman­hang kan vara att lastbärare försvinner i leveransflödet vilket kan vara både kostsamt och reducera kundnöjdheten. RFID, Radio Frequency Identificat­ion är en teknik som kan användas i logistikprocesser för att ge en ökad synlighet på både lager-och logistik­aktiviteter i flödet från leverantör till kund. För att kunna driftsätta en sådan lösning och få tillgång till den tänkta nyttan bör de invol­verade aktörerna engageras i ett gemensamt system som kräver uppsättningen av en lämplig infrastruktur. Brunskoggruppen AB är ett mindre logistikföretag beläget i Ljungby som upplever ökade kostnader för förlorade lastbärare i leveransflödet och ett be­hov av effektivisering av informationsflödet gällande densamma.Syftet med denna studie var att genom litteraturstudier, intervjuer och inslag av aktionsforskning undersöka och ge ett exempel på hur Brunskoggruppen AB kan införa en automatiserad lösning för spårbarhet på lastbärare.

Uppleva eller leva upp till? : En studie om hur gymnasieelever upplever prestationskrav i idrott och hälsa.

AimThe purpose of the study was to investigate how upper secondary school students experience performance demands during their physical education and health classes (PE-classes). The questions were as following: Are there differing perceptions between the sexes whether students experience performance demands? In what situations do the students feel that the demands on their performance are high during PE-classes? Do the students experience of demands on performance differ whether the physical education and health teacher is male or female? Do students feel unfairly treated by the physical education and health teacher during PE-classes?MethodSeven upper secondary schools in Stockholm?s administrative district were randomly selected to participate in the survey. The principals were contacted for further information and to set a date for performing the survey. The project leaders were present during the days the surveys were taken by students in the social science and natural science programs.

Svensk vindkraft

Sweden's drinking water quality is considered to be high partly due to a high quality of the raw water and a well developed sewage infrastructure. Despite this, there is water contamination that could be prevented by installation of a sophisticated early warning system. Some of the major players in the production of drinking water have already invested in different types of early warning systems to ensure drinking water of high quality. There are various forms of early warning systems where automatic monitoring of E. Coli is an interesting alternative.

Korsförlamning hos häst : fodrets påverkan

The purpose of this thesis has been to gather knowledge about the complaints of tying-up in horses and to show that the importance of feeding. The thesis includes a literature review of tying-up how preventative measures by feeding can be made. In the equine sport, crosscountry, horses occasionally suffers from tying-up, a muscle disease. An increased knowledge about the disease is demanded by riders and trainers as the disease disrupts training and competition of suffered horses. A cross-country horse works very hard in training and during competitions but the work bouts are long enough for the muscle cells to use aerobic pathways in the metabolism.

Datorspel = Lärande? : En kvalitativ studie angående gymnasieelevers attityder gällande datorspel som läromedel

The gaming market has become the fastest growing market for leisure and is one of the most popular forms of homeentertainment. This has generated a media debate about how people are affected by gaming and concernes how we are affected by the violence that may occur in games. Games proponents argues that gaming is the future of teaching and computer games are becoming a sustainable and popular instruction strategy. Some studies have long used computer games for educational purposes. By interviewing high school students in focus groups as qualitative research, I studied their attitudes towards computer games as a learning tool.

It?s a Guru Thing - Vlog Popularity in the Beauty Community : En kvantitativ samt kvalitativ studie om vad det a?r i sko?nhetsvideor som genererar visningar.

The overall purpose of this essay is to come to a deeper understanding about videos in the Youtube beauty community by using a mixture of qualitative and quantitative methods. By answering the main questions of the essay which are; What quantitatively measurable components are there in the videos that can be seen as contributing factors leading to the fact that some generate more views that others?; Is there a set mold for success containing certain aspects that a video must have to stand out?; What correlations can be found between the two categories of analysis and how do these potential correlations affect the popularity of the video? and What effects do specific components on the level of popularity of the video?, we?ve been able to distinguish differences as well as similarities on both qualitative and quantitative levels. We have also seen that using the two methods together have enabled us to reach more profound results. The main result that we have found on a quantitative level is that there are obvious correlations between a high level of popularity and a good visual quality.
