Using themutual sickness benefit societies in Sweden as variable for voluntary associations around1884, the essay discusses the possible links between social capital, associations and long termeconomic development.
TT och utlandsbilden : En kvantitativ innehållsanalys av utlandsbilden i Sveriges största nyhetsbyrå.
The purpose of this study was to examine the foreign news flow in Sweden´s largest news agency TT. Since TT has an important position as a news provider to most of Sweden´s local and national news outlets, it was important to examine exactly what their news stories consisted of.The theoretical background of this study consist of theories of news values, agenda setting, dependency theory and the theory about the ?news shadow? a lack of coverage leads to.In our quantitative study we have looked at 506 articles taken from the TT news flow during two weeks In November 2013. We have studied which continents and countries the news origins from, who have supplied the text, the topics of the news, which one gets to speak in the text and what general tone the story has.The study shows that the supply of news follows the criteria of news values. It also shows that in some regions of the world the coverage is almost nonexistent.
Pojkar bör och pojkar gör : Om maskulinitetsskapande i gymnasiet
This thesis aims to spread some light over the phenomena of gender construction in the upper secondary school. The background of this thesis is the gender gap in education. Girls are more successful in school and receive better grades than boys. The explanation that is given for this is that pupils are limited by far to rigid gender roles (DEJA 2010). The question is how these gender roles ? and specifically masculinity ? are constructed.
Inventering av trädbränsleaskor : en sammanställning av spridningsbar aska i södra Sverige
I takt med ökande intresse för uttag av grot så ökar också intresset för återföring av aska tillbaka till skogen. I rapporten utreds hur mycket återföringsbar aska som produceras av förbränningsanläggningar. Arbetet begränsas genom att endast förbränningsanläggningar med större kapacitet än 10 GWh träbränsle per år tas med . Dessutom sker en avgränsning geografiskt till att endast ta med anläggningar placerade söder om en tänkt linje mellan Karlstad och Stockholm.Datainsamlingen för förbränningsanläggningarnas askmängder har gjorts både med telefonintervju och enkätundersökning. Totalt har 107 förbränningsanläggningar tillfrågat.
Undersöka förbättringspotential med verktyg från Lean produktion
In the year 1783 a fissure eruption from Laki in the southern part of Iceland produced a large amount of volcanic gases during a period of eight months. The volcanic gases and aerosols spread across the northern hem sphere due to ideal weather conditions and had a substantial impact on the environment, human health and also climate effects. This, so called dry fog, caused severe health problems, which led to death casualties, killing animals, crops and other vegetation. The consequence was a widespread famine which was aggravated by a hard and long winter in 1783/84. Analysis shows that the Icelandic volcanoes are the primary risk to produce dry fog that can affect Sweden.
Förvildade husdjur : möjligheter och hot
Feral animal populations are distributed over many parts of the world and are often seen as a problem. Since they are a threat against other species, destroy farmlands and can spread dis-eases, they are often referred to as pests. Artificial selection has contributed to loss of genetic diversity in our domesticated animals. Feral animal populations are affected by natural selec-tion, which allows them to adapt to the environment. Their ability to adapt is a reason to see them as pests but can also be seen as an asset.
?Till Skriptoriet i hopp om excerpering? ? Om uppbyggnaden av Svenska Akademiens Ordboks bibliotek
This thesis deals with the question of why the Swedish Academy Dictionary has its own Library when, for almost a hundred years, it has been located at the University Library of Lund. Looking at the library functions: librarian, users, room and books and their external factors: economy, internal actors, external actors and the development of the Swedish Academy Dictionary helped to shed light upon which relations between these factors have been important in the development of the library. The results show that there has not been a conscious plan behind the Library. A large number of the books in the Library was given by those who have worked at the Dictionary and also by their friends and collegues. Another part was given by the Swedish Academy and was partly gathered when the project was still in Stockholm.
Är Facebook den nya tidens politiska kanal? : En studie om påverkan genom Facebook.
During the last years social media have developed and become a place where all kind of people can meet and interact with each other without any kind of physical contact to one another. We belive that this development also has made it easier for political parties and organisations to spread their propaganda to the people that uses social media without them knew from whom the information is coming. With this in mind we decided to do a study about the social media Facebook and how the users of Facebook think they are being influenced by political propaganda from organisations and private persons. In our study we decided that we wanted to know why our respondents are using Facebook, if they have payed attention to two political questions, one international question and one national question, that have been noticed recently and if they feel that they are being influenced of political propaganda when they are using Facebook. We have concluded that our respondents, depending on how old they are, do feel that they are being influenced by political propaganda when they are using Facebook. We have also noticed that the younger part of our respondents feel that they are using Facebook because their friends do it and that they have noticed the international political question more than the national political question. In the older category of respondents the reason of why they are using Facebook was to maintain a conection with their friends and they had noticed the national political question more than the international political question. .

Varför kan man tvätta med tvättnötter (Sapindus mukorossi)? : en litteraturstudie om de aktiva ämnena i tvättnötter och hur de fungerar vid tvätt av kläder
Soapnuts have been used as a cleaning detergent and medicine since ancient times in different parts of Asia. Today soapnuts are sold as an environmentally friendly alternative to common washing detergents. The aim of this literary study is to give an answer to what it is in the soapnuts that makes them work as a washing detergent. The active component belongs to a group of components called saponins which are secondary metabolites with the purpose to protect the tree from pathogen attacks. Saponins are widely spread in the vegetable kingdom and some of the families and species are so rich in saponins that their names are influenced by this, for example Sapnindaceae and Sapindus which are mentioned in the beginning of this literary study.
Vibrationsproblem i närliggande konstruktioner i samband med markarbete
Ground work like blasting, piling and excavation has always had a great influence during the planning phase of a construction project since it can cause damages on adjacent buildings and have severe economic consequences. This thesis deals with how vibrations caused by ground work influence near-by buildings and what methods geotechnicians and construction entrepreneurs use to handle these risks.The purpose of this thesis is to explain risk management in relation to ground work. In order to achieve this I have used a qualitative method by interviewing a geotechnician and a ground work contractor who possess knowledge and experience useful to this thesis. The result shows that vibrations from ground work spread through the ground as seismic waves that cause displacements and packing in the ground visible in adjacent buildings as cracks and subsidence damages. Geotechnicians study ground work vibrations by means of ground investigations and experience from previous projects in order to produce a risk analysis that entrepreneurs can use to reduce damages.
Erfarenhetsåterföring i Sveriges två ledande byggbolag : Riktlinjer, utfall och konsekvenser
The construction industry in Sweden has in the past 50 years had a low progress in efficiency. With a greater competition from construction firms from other countries, it is necessary to maintain the profit for Swedish construction firms. This is possible with a higher feedback of experience. This diploma work thesis examines how the two construction companies NCC and Skanska in Uppsala, Sweden handle experience feedback from previous projects and the extent to which the experience is spread and used in future projects. In this work, we examined directorial documents to see how employees shall work with feedback.
Endast en utopi eller en realitet? En studie om Malmö stads interkulturella förhållningssätt i skolan
Since a decade back in time, Sweden is officially recognised as a multicultural society. Different cultures exist side by side and the city of Malmo is one of the clearest examples of this setting. In multicultural societies, the dichotomy of ?us? versus ?them? is common, which leads to segregation and asymmetrical relations of power. The concept of intercultural education is in theory known to be able to create a position of ?us? where every culture is equally recognized and reinterpreted and thus become an alternative to the dichotomy.
Nulagesanalys av svensk e-handel. En undersokning om hur tjanster anvands av foretag for at bemota kundkrav
The Swedish e-commerce has been established for about 25 years, with strong growth from the millennium onwards. The companies that are active within it has many different backgrounds. Mail order companies were some of the early adaptors but today it is also common for companies to first create the e-commerce part of the business, before opening a store. A long list of companies has over the years come and gone, the rotation of the e-shops that are popular have constantly changed. We asked ourselves why.We wanted to get an understanding of the Swedish e-commerce, both from a business perspective and from a customer perspective.
Finns det någon som lyssnar?: -Om kunskapsspridning vid repatriering
The purpose of this thesis is to study how organisations are working with repatriation of employees who have been working abroad, especially regarding how their experiences and competences are being utilised and transferred within the company. A qualitative abductive method is used, since the aim is to obtain an understanding of this phenomenon. The main source of information has been 21 interviews. The interviews were executed in two steps; a preliminary study with nine Swedish organisations was followed by our main study, containing 12 interviews with repatriates, their colleagues, and personnel employed at the International Assignment departments at Scania and Volvo. The conclusion of this thesis is that large Swedish companies, which have Swedish employees working abroad do not seem to be working with repatriation according to suggestions given by the theories, even though their performances are better than earlier research implies.
