Den Digitala Identiteten : En kvalitativ studie om identitetskonstruktion på internet

The purpose of this paper is to increase knowledge and understanding of how an identity is constructed on the internet and if it is different from the everyday identity. To analyze this, I have studied the theories of how identity is constructed in everyday life and then applied this on the empirical data that I have collected. In this study, I have chosen to pursue a qualitative approach using semi-structured interviews to gather the empirical data. In the study, six informants participated and all of them has an active social life both on and off the internet. The results that I have found in this study shows that an identity online is constructed in a similar way as it does in real life, however, some limitations that exist in everyday life do not exist online.

Framtidens mobilnät

The purpose of this project was to study how the interference between two antennas in a MIMO system affects the linearity of the power amplifiers powering the antennas. For the MIMO system, two power amplifiers and twoantennas were constructed and designed using the software ADS and a software defined radio was constructed using the platform USRP and the software LabVIEW. The result was that the interference between the antennas affectsthe linearity of the power amplifiers powering the antennas adversely and a reasonable theory was that the interaction decreases inversely proportional tothe square of the distance..

Förändringar i markanvändning över tid och dess påverkan på vattenkvalitet

The EU Water Framework Directive has led that management follows the boundaries of natural catchments.The Swedish waters suffer from a nutrient overload that originates mainly from diffuse sources such as agriculture and the subcatchment of Hackstabäcken in Vallentuna Kommun, just north of Stockholm, has been chosen for this study because of its high nutrient load and because it has undergone obvious changes in land use through the years.In this study, the land use in 1902 is compared with the land use in 2011 in order to investigate if it has influenced the ability of the landscape to produce ecosystem services related to nutrient removal. These services will continue to be produced as long as the system is stable and resilient, but when landuse changes and manure from horses increases it will lead to disturbances that can convert a system from one regime in to a completely different one. That will result in loss, or degradation, of ecosystem services such as denitrification, phosphor sedimentation and adsorption, vegetation uptake and infiltration.The results of this study are based upon area calculations of landuse from old maps from 1902 and 2011. Through these maps it becomes clear that the forests in Hackstabäcken, has increased with 170 ha together with an urbanization of 311 ha, at the same time as wetlands and arable land has diminished and lakes has suffered from reductions. Wetlands have been reduced with 76 ha and the ones remaining are of insufficient quality from a nutrient removal perspective.Data from 1902 and 2011 regarding number of horses and bovines indicated a decrease in bovines and an increase in horses.

Barnperspektiv, betyder barnrelaterat? : En kritisk diskursanalys av barnperspektivet i tjugosex kulturmyndigheters och -institutioners strategier fo?r barn- och ungaverksamhet (2012-2014)

Today the right of the child to participate freely in cultural life and the arts is a goal on the political agenda. As a consequence, in 2011, twenty-six government agencies and institutions of culture were assigned to formulate strategies for activities for children and young people. These strategies are the empirical basis of this thesis. The aim of the study is to elaborate and problematize three issues concerning children?s culture from the viewpoint of a social constructionist understanding of childhood as constructed in various, often political, practices.

Aktivt balanserad cykel

To conclude this year?s introductory course in Mechatronics the students, in groups of 6,constructed a prototype based on the technical requirements established by the course teachers.This year they consisted of the following: two wheels only, active balancing, remote controlledand able to stop when crossing a pre-determined marker on the ground. The project lasted for 7weeks and the result is a working prototype and this report.The report reviews the chosen solution, subsystems and the finished prototype as well assuggestions for improvements, discussion and analysis.The prototype constructed embodied most of the group?s earlier individual technical specialtiesand consists of the following: a flywheel for balancing, ultrasound for angle measurement, areflective photomicrosensor to detect the marker and Bluetooth for the hand control..

Bortom ?könet?? : om Simones förvandling, avslöjande och återställande i Ulf Starks Dårfinkar & dönickar (1984)

The aim of this paper is to analyse how subject, gender and sexuality is constructed in the book Dårfinkar & dönickar (1984), by Ulf Stark. In relation to this I have also analysed how the main character, Simone, develops from being a child into becoming a teenager.Queertheory is the theoretical basis of this paper. Queer theory questions heteronormativity and aims to dissolve conceptions and notions that function in an excluding and limiting way. Queer theory also questions conceptions that seem obvious and/or natural, for example ?woman?/?man? and ?homo-/heterosexuality?.I have chosen to focus the analysis on a number key events in the book and they are categorised according to Tiina Rosenberg`s three dramaturgic concepts: transformation, unveiling and restoration.

Dikesrensning och skyddsdikning : en fältstudie och utredning av behov i södra Sverige

During the 20th century a significant proportion (about 15 %) of the peat-covered wetlands in Sweden were drained to improve forest productivity. Area wise, most of the forest drainage was done in northern Sweden, but relatively speaking a larger part of the wetlands have been drained in the southern parts of the country. Most often, the forest drainage resulted in increased forest growth, but failures were not unusual, and harmful effects, e.g. on species richness, have been a common cause for draining. Ditch cleaning is necessary for maintaining the ditches in good condition.

Näringsbelastning på en anlagd våtmark från åker, skog och enskilda avlopp :

This work is a part of the project ?Våtmarker i odlingslandskapet ? uppföljning av miljömålen? (Wetlands in arable land ? following-up of the environmental goals). The main objective with this project is to study nitrogen and phosphorus retention in a constructed wetland by using mass balance calculations. Continuous measurements of nutrients and water flow through the inlet and the outlet of the wetland are made. However, substantial amounts of nitrogen and phosphorus were assumed to reach the wetland with a drain-pipe transporting wastewater from nearby houses (10 persons).

Folkbibliotek och IT diskurser om folkbibliotek och informationsteknologi i fyra bibliotekstidskrifter

The aim of this Masters thesis is to examine public library and information technology IT discourses to see which relationships are established between them in four library journals. This is done in two steps, where first discourses are defined followed by an analysis of the relationships established between the public library and IT in each discourse. The questions from which the analysis emanates are as follows: What discourses exist around the public library and IT in the library journals? What conceptions of the tasks of the public library are constructed in the discourses? What conceptions of the tasks of IT are constructed in the discourses? What conceptions of the relationships between the public library and IT are constructed in the discourses? The theoretical and methodological starting-points are found in Ernesto Laclaus and Chantal Mouffes discourse theory. 37 articles from four library journals Biblioteksbladet, Bibliotek i Samhälle, DIK-forum and Ikoner - are analysed through a model in five phases.

Sedimentprovtagning av dagvattendammar som ett alternativ till flödesproportionell vattenprovtagning

Stormwater run-off from surfaces such as roads or rooftops is often polluted with heavy metals and nutrients. Many of these substances can cause great damage in biota if they end up in the recipient. In Sweden Constructed wetlands and ponds for treatment of stormwater are frequently used, since research has shown that these treatment ponds are reducing stormwater pollution considerably to a low cost. The knowledge of these pollutant removal mechanisms and how follow-up and assessment of the ponds should be performed is still limited.To determine the pollutant removal efficiency of the stormwater ponds it is recommended that flow-weighted water samples are collected from both the inflow and the outflow of the pond. This method demands considerable resources of time and money for installations and analysis.

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.

Hur konstrueras användare och bibliotek på svenska folkbiblioteks webbplatser ur ett webb 2.0- perspektiv?

The aim of this thesis is to find out how users and libraries are constructed at public library websites in Sweden from a web 2.0 perspective. We discuss the development of public libraries in Swedish history and the change from an system oriented perspective to a individual oriented perspective and how these perspectives correspond to needs of the library user. We also discuss the concept of web 2.0 and library 2.0. These concepts are open for different interpretations. Some writers believe that web 2.0 and library 2.0 is something radically new and that it will change the public libraries, while other writers claim that these concepts is just a marketing plan.

Inkludering på olika villkor : En dokumentstudie av aktuella politiska diskurser om integration

The purpose of this essay is to examine the Swedish governments discourse on integration of immigrants and thereby examine what social reality it constructs. The aim is to examine how integration and immigrants are constructed within the discourse. The method and theory being used in this essay is discourse theory. As a methodological instrument we use the policy on functional impairment as a comparison. The material being analyzed in this essay is political documents on the strategy on integration policy and the strategy on the policy of functional impairment.

Konstgjorda våtmarksöar : flytande reningsverk?

År 2000 godkände Sverige EUs vattendirektiv. Det innebär att vi måste arbeta för att vattnet ska ha en god kvalité och det får inte ha för höga halter av förorenade ämnen. Vid förorening kan vattnet skada människor, djur och växter. Sverige måste ständigt jobba och förbättra reningen av vårt dagvatten. Reningen av dagvattnet och på vilket sätt det ska ske är något som ständigt kan förnyas och förbättras. Idag renas dagvatten med hjälp av dammar och våtmarker och reningen kan bli bättre med hjälp av flytande våtmarker. Syftet med denna uppsats har varit att ta fram mer information om flytande våtmarker och att sprida denna så att intresset och kunskapen ökar och förhoppningsvis även användningen av dem så att reningen av dagvattnet kan förbättras. Arbetet innehåller en litteraturstudie och resultat från intervjuer vilka bägge syftar att ta reda på hur en flytande våtmark fungerar, hur den är konstruerad, vilken typ av skötsel den kräver, vilka växter som fungerar bäst, hur de renar vattnet och hur man skulle kunna använda sig av dem här i Sverige. I arbetet finns det information om när en flytande våtmark renar som bäst, vilka typer av växter som bör användas och vilka typer av stommar det finns till den flytande våtmarken.

Lättläst information i e-förvaltningens tid : En studie om lättläst information när myndigheterna satsar på webben

The overall aim of this thesis is to examine how Easy-to-Read information, used by governmental agencies, facilitates and limits the field of possibilities for the intended recipient, based on the information.This, in anera of e-government.The theoretical framework is based on two Foucauldian concepts governmentality and discourse analysis. Representatives from five Swedish governmental agencies have been interviewed and the results have been analyzed based on the following questions: (1) How do the representatives construct the category Easy-to-Read? (2) How do these representatives construct the recipients of Easy-to-Read? In order to broaden the understanding of Easy-to-Read, an important national level policy document, containing a summary of strategies and goals for e-government has also been analyzed based on the following questions: (3) How is the e-government constructed in the text? (4) How is the citizen constructed and positioned in the text? The collected material is analyzed using a discourse analysis inspired by Foucault.With the results from the interviews and the analyzis of the policy document, Easy-to-Read information has been discussed and examined as a technology to meet the needs of people with reading difficulties, putin an era of e-government.The findings of the study include the following: (1) The e-government is constructed as a service agency and the citizens are positioned as clients. Furthermore, the citizens are expected to participate digitally and be digitally competent. (2)Some of the representatives does not know, with certainty, to whom the texts are directed or if they are used.
