Måste Aftonbladet minnas vad en jämtländsk by heter? : En kvalitativ studie av hur jämtländska nyheter porträtteras i rikstäckande press

For years the northern parts of Sweden, Norrland (translated: North land) has been considered mystified and exotified by the southern, more urban parts of the country. The rural Norrland ? though 60 percent of Sweden ? is seldom a part of the common conversation, meaning that most of the people living in the southern parts simply have no idea what is happening in the north. The one million people living in Norrland, on the other hand, every day gets to know what happens in the south on the evening news. The question about this possible structural relation between the urban and the rural became a large matter of cultural debate in the spring of 2015, If this thesis is true, we have a problem on our hands; can the national news be considered national if half the country is misrepresented? That question is what this essay is trying to find out by analyzing two of Swedens largest national newspapers.

Grundvattensänkning till följd av järnvägstunnel genom Hallandsås : miljökonsekvenser relaterade till förändrad kväveomsättning i mark

This thesis was carried out to give some background information to a report of SLU (Swedish University of Agricultural Sciences) for the Swedish National Rail Administration (Banverket). The requested information was to provide basic data for an environmental impact assessment of the construction of the tunnel through Hallandsås. The aim with the thesis work was to discuss and quantify the leaching of nitrate and the emission of nitrous oxide from the soil at the groundwater level established through the tunnel project. The nitrogen related processes that could be affected were described and discussed. The different areas where a decreased groundwater level can cause changes in the nitrogen processes are the wet and moist areas.

Möjligheter att minska kväveutlakningen genom att anpassa kvävegödslingen till variationer inom stråsädesfält

Due to excess precipitation that cause runoff, all soils in Sweden naturally leaches nitrogen.High leaching from arable land is an environmental problem when the runoff reacheswaters. In the international agreement, Baltic Sea Action Plan, the aim is to reduce therunoff of nutrients. Sweden has agreed to reduce its load of e.g. nitrogen to the Baltic Sea.One of the proposed measures is an increased use of site-specific N-fertilization, which hasbeen shown to increase nitrogen use efficiency and therefore also reduce the nitrogen runoff.Either yields are increased with the same total amount of nitrogen, or the total quantityof nitrogen is reduced with preserved yield levels, which is profitable for the farmers.The dynamics of nitrogen leaching differs between top dressing applications above orbelow the economical optimum. There is a consensus about a difference in the dynamics,but not about its magnitude.

Kommunicerbara Informationssystem

Nowadays naval units are participating in international missions, where new and in many cases tougher conditions will affect their propulsion. This essay deals with some of the now developed nanostructure coatings and gives a presentation of how the coatings could function on some exposed parts of the naval powertrain. The essay investigates the possibility that the coatings can be used as a protective layer that will reduce or prevent wear on selected parts of the naval powertrains. As a basis for the essay, nanotechnology is described, as well as different reasons that wear occurs and application techniques for coatings The conclusion is that nanostructured coatings can be applied and provide a much better result on hardness and wear resistance as of naval powertrains compared to micro-structural coatings, both for manufacturing and renovation. The essay presents a few examples of the military utility of the nanostructure coatings as well as suggestions for further research..

Förskolebarns motoriska utveckling : -Hur en förskolegård bör utformas för bästa tänkbara utveckling av barns motorik

The purpose of this study was to interview different groups of people (preschool teatcher, parents and theire childen) involved in preschool about their view on outdoor activity and children´s motoric development, and how a preschool yard should be designed to promote childrens development.All parties regard outdoor activity as very important for the development of children. They also think that the outdoor environment today is good but that it could be improved by including some trees and hills. The yard should also contain soil, sand, clay and water. The children prefer grass on the ground over other substrates. This study also gives good indications to decision makers how to build new or to reconstruct pre-school yards in the future..

Betula : arter och sorter

As birch is one of the most common trees in Sweden, and probably one of the easiest for someone who lives here to identify, it is interesting to note that most people do not know how variable the genus is and how widely it is distributed across the northern hemisphere. One can find birch growing at both high and low elevations, demanding different soil conditions and preferring varying amounts of sunlight. Many people may also be surprised to hear that the colour of the bark can vary from bight white to almost black, and different shades of pink, orange and red can also be displayed. This, together with the astonishing beauty of the genus, the important role as a pioneer in many ecological systems and the difficulty in sorting out the taxonomy of the genus, constitutes the background of this thesis. The thesis is written at the Department of Landscape Development in Alnarp, Sweden with Kenneth Lorentzon, researcher at the Swedish University of Agriculture as a supervisor. The aim of this thesis is to highlight which species and cultivars within the genus Betula could be appropriate for horticultural use in Sweden.

Roadmate re:design : Design- och utvecklingsprocessen vid redesign av en digital tjänst

This report describes the initial work intended for updating the car sharing service Roadmate. Roadmate is one of the services received by the car rental company Hertz First Rent a Car. The goal was to present the client with design- and structure proposals for a car sharing service that includes high usability and at the same time remains aesthetically pleasing.The work is based on an initial study with data collection, mapping the target user group and its needs. Subsequent structural and design proposals for Roadmates company carpooling service are based on the facts surrounding the target group's needs. The result are well developed and tested design sketches with accompanying visual identity and sitemaps that can be the basis for the further work on the development of the service..

Är bor nödvändigt vid skogsgödsling i Sverige?

This thesis has been made on behalf of SCA Skog AB to assess the need of boron in Swedishforest fertilization. Boron has been added to Swedish forest fertilizers since the beginning of the1980s. This makes the fertilizers more expensive and therefore has the necessity of boron inSwedish forest fertilization been raised.The Swedish bedrock generally contains small amounts of boron. The boron in the bedrock istightly bound to the mineral tourmaline and mostly unavailable for plants. This leads to that thecontribution of boron to the soil from weathering is very low besides soils with marinesediments.

Kväveläckage inom Tolångaåns dräneringsområde : modellering och åtgärdssimulering

Under de senaste 300 åren har jordbrukslandskapet i Sverige genomgått stora förändringar. I början av 1900-talet introducerades konstgödslet och efter andra världskriget ökade gödslingen dramatiskt i syfte att maximera produktionen. Detta har lett till att överskottet av kväve har spolats ut i vattendragen. I detta arbete har stor vikt lagts vid att skapa en egen kvävemodell i syfte att simulera kväveläckaget från jordbruksmarken i Tolångaåns dräneringsområde..

Managing the integration process in a merger. Case: Cloetta Fazer

Background: Mergers have been increasing during the latter part of the 1990s. In the Nordic region many previously national companies have joined their forces to create a new Nordic company. This will lead to many challenges when the companies are integrated.Purpose: The purpose of this thesis is to investigate the integration phase. Our goal is to study the integration of Cloetta Fazer and learn how the company can handle the two types of integration. Procedure: To be able to prove our assumptions, that were made on the basis of literature, we have collected empirical material by interviewing eight managers at Cloetta Fazer.

Spårelement i Sveriges jordbruksmark : flöden, trender och fältbalanser

Field balances based on supply and removal of trace elements from the topsoil have been calculatedfor farms specialized in crop, dairy and pig production in Sweden. Today's field balances have beencompared with the field balances of 1990 in order to examine if, and then how, the situation haschanged. Studied trace elements are arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu),mercury (Hg), manganese (Mn), nickel (Ni), lead (Pb) and zinc (Zn).The balance calculations show that the stores of Cu and Zn are depleted with an average rate of -15% and -6 % over a 100-years period on crop farms when only commercial fertilizers are being used.The concentrations of Hg and Pb tend to increase in the topsoil on crop farms with more than 3 % forHg and with 2 % for Pb in 100 years. There is today balance between supply and removal of the traceelements As, Cd, Cr, Mn and Ni. In the south of Sweden, on crop farms with sugar beets in the croprotation, one can see a decrease in the concentration of Cd in the top soil by -6 % over a period of100 years.

Samhörighet och struktur - en studie av invandrargruppens politiska mobilisering

This essay deals with the paradox of why the immigrants in Sweden, despite their considerable size of 12 % of the population and common interest and living opportunities, haven?t mobilized politically in any significant way. The aim with this essay is to reach a theoretical understanding of why this paradox exist. By the use of a critical case and a theoretical model, based on theories of collective action, the conclusion of this essay is that, despite the fact that the immigrants have a common interest and an organizational structure, the immigrants in Sweden has not mobilized politically in any significant way. The main reason for this is that they have a weak common identity and they don?t have the structural opportunities to act..

Kvinnlig chef i byggbranchen : faktorer som utgör hinder till avancemang

Background: Studies that have been made in male-dominated organisations shows that only few women have succeeded in advancing to the higher positions in all businesses. Statistics shows that merely 4 % of the managers in all building companies are female. The manager role has earlier always been classified as most suitable for men resulting in barriers for women who strive for management positions. This problem is now very renowned and is called the glass ceiling. To improve the current situation, both the organization's structure and culture, have to be modernized for more women to succeed and get the courage to get into the industry.

Skogsentreprenör 2007 : en kvantitativ studie av organiserade skogsentreprenörer i Sverige

SMF Skogsentreprenörerna is a nationwide organisation for Swedish forestry contractors. It has about 750 organised companies with somewhere around 1500 logging machines. These machines perform well over 50% of all yearly landed wood in Sweden. The members of SMF also performs more and more of other functions in Swedish professional forestry, such as soil scarification, planting and pre-commercial thinning of younger stands. In order to determine what major priorities SMF should focus on in the future a member survey was initialised and carried out by SMF together with Daniel Larsson-Snygg, student at the swedish university of agricultural sciences SLU. This report presents the result of this survey sent out to all members of SMF. It is intended to answer a number of questions about their entrepreneurship such as: What different kinds of work do these companies perform? How many machines and employees do they have? How old are the company owners and their employees? What are their thoughts about the future of their business? How well does SMF serve their members needs?.

Socialtjänstens behandlingsarbete för män som utövar våld mot kvinnor : En kvalitativ studie om vilken innebörd teori har för behandling

The purpose of this study has been to increase the awareness of what significance models of explanation have for intervention programmes, aimed at perpetrators of intimate partner violence, within the Swedish social services. The study is not gender neutral, it centres on male batterers in heterosexual relationships. The study is based on qualitative interviews with five people working within the topical field. I analyzed their statements using an ecological model of understanding violence. The main finding was that the people I interviewed had a multiple understanding when it came to comprehending the violence, but that when it came down to the actual intervention they targeted mainly on elements in the individual spectra, such as feelings of frustration.
