"Man vill ju se bra ut" : En kvalitativ studie om ungdomars syn på sociala medier

This thesis examines young people's thoughts about their presence on social media. With asocial constructive approach the study focused on how young people think and act on socialmedia in relation to constructions of gender and normality. The analysis is based on fourgroup interviews with 13-year old boys and girls. The theoretical approach is based partly onsocial constructionism where discourses and ideas of normality are identified and analyzed.Erving Goffman's theory of social interaction was central to illustrate how young peoplepresents themselves based on the prevailing discourses. It is clear that they adjust theirrepresentations of themselves depending on the context.

ESC-analys och studering av knack på en "Diesel Dual Fuel"-motor

A one-cylinder research engine has been used for studies with a Diesel Dual Fuel concept (DDF). DDF is a concept that utilizes a pilot diesel injection to ignite a homogenous natural gas/air mixture. Emissions and engine efficiency have been analyzed in an emission cycle called European Stationary Cycle (ESC) and the knock/pre-ignition problems with this type of engine have been investigated.At low and mid torque levels, an early diesel injection around 60 crank angles degrees (CAD) before top dead center (TDC) was used. At these loads raw NOxemissions was below EURO 6 level (0.2 g/kWh). NOxwas at EURO 5 level over the complete ESC without after treatment and with SCR at high loads it should be possible to reach EURO 6.One issue with DDF is the high HC emission levels.

Cystisk endometriehyperplasi/pyometra-komplexet hos hund : orsaker och patogenes

Virulent strains of Staphylococcus hyicus produce exfoliative toxins and cause a potentially fatal skin disease in piglets known as exudative epidermitis. Vaccines and antimicrobials are used to control the disease. Antimicrobial resistance and the prevalence of several different toxin genes and toxigenic strains make it problematic. The aim of this literature study was to identify potential differences between countries and between healthy and diseased pigs regarding antimicrobial resistance and toxin-producing strains. Great differences could influence vaccine production, treatment strategies and surveillance programs.

Jordbruk kontra industri : jordbruksregleringar ur marknadsstrukturmässigt perspektiv

What is the?self? and to become ?one-self?? To resolve this questions possibility I´ve been using the philosopher Søren Kierkegaard metaphysic paradoxes. This essay about the ?self? shows the reader the difference between describing a transcendent and immanent phenomenon and if it´s possible to become or to not become ourselves. The process is a key of the ?self? which Kierkegaard explains the ?self? in and for it-self.

Brukarmedverkan i förvaltning av tätortsnära naturmark :

Flera kommunala förvaltningar och andra instanser efterfrågar idag former för hur brukare aktivt kan involveras i skötsel av tätortsnära skog- och naturmarker. Erfarenheter finns, men delgivning av goda exempel och bra referenser är en bristvara. Genom detta examensarbete presenteras en form för hur skötsel av en tätortsnära skogs- och naturmiljö praktiskt kan genomföras tillsammans med de boende i närområdet. Förslaget för samarbetet har utformats via en fallstudie och baseras på intervjuer med boende och förvaltare inom ett avgränsat villaområde i Huskvarna. Studien redogör även för synpunkter och de krav som lyftes fram av respektive part inför samverkanssituationen, dvs. samverkanspotentialen och själva ramen för samverkan.

Våtmarker i urbana miljöer : växtgestaltning och planering

The practice of landscape architectural involves forming the space in our cities and suburbs, as well as the landscape surrounding. The need of exploiting green environment leads up to, among other issues, flood problem during heavy rain and overfed water environments. The problem is partially caused by the shortage of knowledge, how the environment is responding of the innovations made by the city- urban planning and how to get sustainability. Research and knowledge how to take care of our environment, in a natural way, is increasing. The object of the thesis is to propose control and balance in urban wetlands, and discuss the difference a plant design can do. The thesis deals with discourses in the field of landscape architecture, biological diversity, dam construction, limnology, planting design and management, pollution of the environment and urban design practice.

Intelligenta Switchar

This master thesis has been carried out on behalf of Stoneridge Electronics AB and is an investigation ofhow intelligent switches can replace the traditionally used direct controlled switches. The concept ofintelligent switches is that the switches contain electronic identification components which, by connectingthem to a network, give the same function independent of the location of the switch. This infers anincreased flexibility and configurability which can be a great advantage in development, production andcustomization in the commercial vehicle industry. Especially in the current situation when commercialvehicle manufacturers provides more and more functions and dashboard configurations.LIN (Local Interconnect Network) is a network protocol introduced in 1999. It is a simpler and lower costcomplement to CAN (Controller Area Network) and is adapted for applications where the demands forbandwidth are lower, for example reading sensors and switchers.

?skolan idag bara är till för att indoktrinera och passivisera?. En studie om elevinflytande i en av Malmös gymnasieskolor - [The school today is just to indoctrinate and passive: a study about student participation in an upper secondary school in Malmö]

Democracy is now a legitimate claim not only in the society but even in the classrooms. According to the 1994 Curriculum for the Non-Compulsory School System, Lpf 94 in Sweden, are all pupils in all types of schools ought to have a high level of possibilities to be able to influence their education. But many studies have led to unsatisfactory results about the actual situation in schools. Swedish students are critical of the limited opportunities they have in influencing their own learning process. This essay is only one among the many studies that have dealt with school democracy during the last 50 years.

Hoppa på tåget eller stå kvar vid stationen? : Organisationers användning av sociala medier

Purpose:The purpose of this paper is to investigate and clarify some of the factors that influence organizations to adopt or reject the social media, and if the emergence of social media influenced the organization's communication.Metohodology:A qualitative methodology has been used to execute the study. The source has been semi structured interviews with chosen representatives from several organizations.Theoretical perspective:The theoretical basis for the execution of the methodology is based on the provisional theoretical demarcation uses and gratifications theory. For analysis diffusion of innovations theory is applied.Emperical findings:The empirical material includes interviews with representatives from twelve selected organizations, defined as companies in the industry and authorities, in seven different industries.Conclusion: The main factors affecting an adoption of social media is the organization?s open structure, the ability to see opportunities with social media and that they are seen as a natural part of development in the communications field. The main factors affecting a rejection of social media is ignorance, the organization's governance and that there must be a need that social media can fill.

Simulation of rattan harvests in Indonesia : different harvesting pressures and the resulting patterns

The objectives of this research were to determine whether the natural rattan resources in Sulawesi, Indonesia can cope with the strongly increased harvesting pressure that has occurred over the last centuries. I was furthermore looking for patterns in the rattan population dynamics that might give a hint on how the harvesting system could be improved to ensure a maximum sustainable yield. To answer these questions, I developed an individual-based model to analyse the dynamics of rattan growth in connection with rattan harvests by locals to identify sustainable levels of rattan harvests around villages in Sulawesi, Indonesia. Scenarios with different harvesting intensities were run to compare the change in harvest amount. For a given harvesting pressure, scenarios with a high number of harvesters and a low harvesting frequency had the same effect as scenarios with high harvesting frequencies and a low number of harvesters.

En utvärdering av Länsstyrelsen i Jämtlands läns uppföljning av den hotade orkidén brunkulla

Det har skett en stor förändring inom det svenska jordbruket det senaste seklet, traditionell slåtter och beteshävd har nästan upphört helt. Förändrad markanvändning orsakar habitatförlust för många växter och djur. Slåtter och betesmarkerna som hör till de artrikaste växtsamhällena i Sverige hotas av igenväxning. I denna uppsats studerar jag Länsstyrelsen i Jämtlands läns uppföljning av den starkt hotade orkidén brunkulla (Gymnadenia nigra) som är en hävdgynnad art på tillbakagång. Studien baseras på intervjuer med anställda på Länsstyrelsen i Jämtlands län samt de inventeringsdata man samlat inom uppföljningen.

Den reproduktiva heterosexualitetens maskulina man och feminina kvinna : En queerteoretisk normstudie av fyra biologi-/naturkunskapsläroböcker producerade 1957-2008 för grundskolans år (3) 4-6

Though still well used in Swedish schools, textbooks are no longer under any governmental control or inspection. It is now responsibilities of the teacher, thus, knowledge is considered crucial. Therefore, the aim of this study was firstly to investigate if and how four biology/natural science textbooks, produced 1957-2008 for primary school years (3) 4-6, expressed any sex, gender and/or sexuality norms. Moreover, due to thoughts of queer theoretic Judith Butler, the study also investigated if and how these three norms interacted. By examining what the textbooks mediated, the purpose was finally to find out if and how the norms differed or not.

Institutions Matters - En teoriprövande studie om institutionell struktur och ekonomiskt välstånd inom transitionsländerna

This thesis analyzes and discusses the role of institutions concerning countries' abilities to create economic wealth. The countries that we are analyzing are the former members of the Warsaw pact and former Yugoslavia. These countries are referred to as transition countries. In order to analyze the transition countries institutional structure we are using Douglass C. North's theory regarding institutions and institutional building.

"Så att få ungarna att förstå att dom är guld, det tycker jag är, det är våran uppgift" : En kvalitativ studie av relationerna mellan ungdomar och behandlare på behandlingskollektivet Hassela i Klintehamn, Gotland.

The purpose of my study was to see what kind of relationships there were between the youth and the social workers in the treatment home Hassela in Klintehamn, Gotland. The social workers work for six weeks day and night by living together with the youth. I also wanted to examine what happens when there were conflicts between them as signs of tensions in the relationships. In addition to this I wanted to study the relations between power and influence in their relationships where Hassela strives for democracy. My questions were the following; How do the youth and the staff describe the relationships between them? How do conflicts work between them at Hassela? What does the relationship between power and influence look like?The study is based on qualitative interviews with four clients and four social workers.
