Självskadebeteende hos unga flickor : en studie om sambandet mellan självskadebeteende och kamkamratgrupper och Internet

Self-destructive behaviour is a more and more occurring phenomenon in today?s society and there are mostly young girls who are affected by this behaviour. There are different explanations to why the phenomenon appears. The purpose of this research essay is to give a literature overview of the phenomenon of self-harming behaviour of young girls. Two research questions have been used to study this phenomenon; How can groups of friends contribute to reinforce an identity with the self-destructive behaviour among young girls? How can Internet contributes to reinforce an identity with the self- estructive behaviour among young girls? For the analysis this research essay uses the social constructive theoretical perspective.

Syntes och egenskapskarakterisering av volframoxid framställd med magnetronsputtring

The system tungsten-oxygen has potential of being suitable for decorative coatings since ceramic coatings are often hard and wear resistant, and since modulations in oxygen content or incorporation of small ions could give bright colours. The aim of this report was to investigate the relationship between process parameters and  the properties of the films, with the wear resistance being of special interest.Samples with tungsten to oxygen ratios in the range of 100:0 to 25:75 at% were made using reactive sputter deposition, either with constant gas flow, or gas flow controlled by optical emission of the plasma. The hysteresis of the system, which means that a certain gas flow will cause different pressure and/or target voltage depending on in what way the flow is reached, makes it interesting to control the process where the system makes the steep change from metallic tungsten to ceramic tungsten oxide. This is difficult and thus requires precise control equipment.The samples were analysed using X-ray diffraction, X-ray photoelectron spectroscopy and an empirical wear test suitable for small components like cell phone cover for example, in order to characterize the structure, composition and wear resistance of the coatings. The results could be divided into three groups: (I) tungsten-like, with very low oxygen content; (II) mixed phase and (III) tungsten oxide like, with oxygen content close to 75 at%.

Storage stability in a milk based UHT-beverage : effect of pH, carrageenan and storage time

The different characteristics of many food products, such as aroma and texture, changes during storage time and become undesirable. The reason is instabilities within the product which become prominent as the product ages. These changes in characteristics are quality losses caused by changes in the product?s intrinsic and extrinsic environment. The stability in UHT-milk and beverages similar to it have been studied in the past decades and a certain focus have been on age gelation which is a common defect in these type of products.

Sveplaserns användning till inventering/befästning/kontroll av vägmarkering

The thesis mission is to investigate whether the swiveling laser that Vectura (former Vägverket Konsult) has in use to measure the road areas and straddle measuring can be used to detect differences in the reflective road markings function. This is to increase use of the swiveling laser and get rid of the manual measurements performed today.Currently, the measurement of road markings reflective function is performed with both mobile and handheld measuring instruments. The purpose of this thesis is to develop better methods for determination of road markings? reflective function, in order to facilitate the description and suggestions for improvements of the maintenance of road markings reflective function.The questions that the thesis has been to start with are:Can the swiveling laser detect differences in longitudinal and transverse road markings reflective function?The accuracy of measurement has been sweeping the laser over the reference instrument (LTL-2000)Is it necessary with a conversion factor for swiveling laser data against the reference instrument data?To answer the question 2 and 3, there has been a field work in Värnamo where a road stretch with longitudinal road markings and zebra crossing (transverse road markings) has been investigated with a swiveling laser and LTL-2000.The formulas and calculations contained in the thesis are drawn from scientific reports that are produced by VTI in Linköping. The same formula that was used to calculate the optical measurement data was also used for the swiveling laser data.

Den ensamma flatan och glitterbögen : En kvalitativ studie av hbtq-personers porträttering i tre olika kvinnomagasin

The aim of this studie centers on how lgbt (lesbian, gay, bisexual, transgender) are portrayed in women?s magazines. The magazines we have chosen to analyze are FRIDA, VeckoRevyn and amelia, which all three have different target groups. We have, with the assistance of the rhetorical and semiotic analysis methods, assessed 18 articles with their associated photographs. These methods are part of the qualitative analysis model and are used in order to study less empirical data with more depth.

Investeringsbeslut för energieffektivisering i monarken

The purpose of this essay is to describe how Boverkets Byggregler has affected the cost ofnewly built houses from 2003 to 2012, to Boverkets Vision 2025. The purpose is also to findagent-principal relations in the construction sector.When investing in an energy efficient house the operating costs are reduced compared to aconventional house. But due to the lower operating costs, the investment cost rises. In thisstudy, we find out if it is economically viable to invest in an energy efficient house comparedto a conventional house from the customer's perspective.The study's approach has been qualitatively where we in collaboration with Derome Hus hadaccess to three conventional reference houses and a passive house and data that was necessaryto conduct viability assessments on houses. We conducted five interviews with people fromDeromekoncernen and Varbergs kommun.The calculation methods we have used in this study are present value method, annuity methodand a sensitivity analysis.

The theory chosen for this study is the sociological perspective. A theory where sociologists such as Emile Drukheim, Talcott Parsons and Pierre Bourdieu are all prominent. The discussion links to Habitus and their theories on social, cultural and collective groups. A qualitative method has been used.

Välfärd - ett begrepp i förändring : En diskursanalys av LSS

In this thesis, the results of a survey regarding grade progression between secondary and upper secondary school in a municipality in the north of Sweden serve as the starting point for a study of the experiences and expectations of a number of 16 year old girls who are in the first year of upper secondary school. The study is performed by means of focus group interviews with female pupils from the three largest upper secondary schools in said municipality in an attempt to gauge their experiences of grades, grade assessment, teacher practices and perceived differences in how boys and girls are treated. The results show that most of the girls are disappointed with upper secondary school so far. Many of them feel that secondary school was both more fun and more rewarding in a sense of learning. Their appreciation of how this more rewarding atmosphere affected their grades differed between the various groups.

Vad innebär EU-Battle Groups insatstid för dess transporter?

Sverige har med sina åtaganden inom EU Battle Groups tagit ansvar för en militär verksamhet som kräver storamått av rörlighet med snabb insatstid. Troliga konflikthärdar kommer inom en överskådlig tid att uppstå långtifrån Skandinaven vilket kräver planering och snabba transporter med stor kapacitet samt lång räckvidd. Enallvarlig kapacitetsbrist i en svensk Battle Group utgörs av bristen på nationella resurser för strategiskatransporter. Avsaknaden av egna militära strategiska transportresurser gör att behovet av civila aktörer och nyagemensamma samverkansformer inom kommunikationstjänsten aktualiseras.Uppsatsens syfte är att analysera hur EU Battle Groups insatstid påverkar transporterna och desstransportförberedelser.Metodmässigt bygger uppsatsen på ett antal frågeställningar vars svar söks genom litteraturstudier ochkvalitativa intervjuer. Den teoriansats som ligger till grund för denna uppsats är systemteorin vilken i sin turhar kompletterats med System Dynamics och dess systemformalisering av materielflöden.Resultat visar på att EU BG med nuvarande resurser inte kan hålla uppsatta tidskrav men med bättreförberedelser kan transporterna påskyndas.

"You call this archaeology" - om uppfattning och fördomar av det arkeologiska yrket med film som ingångspunkt

In my essay I will study the injustice within science in movies, in this particular case: Archaeology. This essay will also examine whether there is reason to believe that there is aconnection between this unfairness and what's being displayed of the archaeologist in popular culture. In my case I have decided to focus on the movie industry because it's a dominant part of our daily life. I have chosen to explore two different groups of students studying an occupation. One is, of course, the archaeological institution at Lund University, and the other is a high school (upper secondary school) program called ?Omvårdnadsprogrammet? at Rönnens in Malmö.

Mångkulturbegreppet i svensk politisk diskurs

This study examines the connection between social capital and urban and rural areas. The study divides the environments into two categories; metropolises and rural areas. Metropolises are defined as any of Swedens largest cities Stockholm, Gothenburg or Malmö. The study also examines if there is a difference between these groups in how high social trust they have to people living in the same areas as themselves versus people who live in other areas. The studie also focuses on the urbanization that the world is going through, where people move from rural areas into the cities for work and education.

Att leva tills man dör - En litteraturstudie om vad livskvalité är för döende cancerpatienter.

The purpose of the study was to discover how nurses can maintain a good quality of life for cancerpatients at the end of life. We examined seven scientific articles in accordance with Polit, Beck & Hungler (2001) criteria for scientific validity. We used Carnevali's (1996) model of demand and resources as a frame of reference. The results showed that physical, psychological, social and spiritual needs affect quality of life in different ways. It also came out that it was difficult to measure something as individual as quality of life..

Sverigedemokraternasanvändning av begreppet?svenskfientlighet? : en diskursanalys

The Sweden Democrats uses a term to describe a situation where ?swedes? are being discriminated against by other ethnic groups and where the elite is promoting this. The term ?svenskfientlighet? can be translated as ?swedofobia? and in this thesis a speech by the party leader Jimmie Åkesson held during the election campaign that solely was dedicated to this term is being analyzed with the help of tools developed by the scholar Ruth Wodak. Ruth Wodak has previously analyzed the rhetoric by other European right-wing-populist parties like FPÖ in Austria and has asked for other researchers to analyze the speech used by right-wing-populist and extremist parties to get a better understanding for just how these parties construct their different enemies.

Tillämpningar i kemiundervisningen : en studie av strategier för att presentera och synliggöra tillämpningar

The aim of this study is to investigate how and in which form students come in contact with practical applications in the upper secondary school course Chemistry B. The study is based upon the assumption that all learning is situated in a social environment. The theoretical framework is the design theory perspective, which entails an assumption that the pedagogical tools affect the knowledge content.The empiric materials in the study are collected through three methods: textbook analysis, classroom observations and questionnaires. Two groups of students and their teachers were observed during a section of the relevant course. The textbook analysis focuses upon the same course section in the textbooks of the two groups and compares these books with the relevant section in a third textbook.

Förbättrar en kvalitetssäkring skördarens dimensionsmätning?

In this study it was investigated if the adoption of a new routine for quality control could improve the precision of the dimension measurement obtained by harvesters. Data was collected from three different harvesters. First, a reference data set was collected before the new procedures had been incorporated, and then when the new methodology was implemented another data set was collected by the harvester operators, allowing the two data set to be compered. The results indicated that following the implementation of the new procedures, the reliability and the precision of the measurements has increased. All harvesters included in the study had improved regarding most of the controlled factors such as standard deviation, systematic difference and hit rate within ± 2 cm for length and ± 4 mm for diameter..
