Högstatus inom presentationsteknik : ekot av alfahannes vrål
Både människor och djur har i alla tider och alla kulturer sett vissa individer i sin omgivning som ledare. De har känt sig manade att lyssna på dem, följa dem och tro på dem. Jag har intresserat mig för vad det är som föranleder detta beteende, eftersom det är min fasta övertygelse att det styr vårt samspel med andra individer än idag, överallt och ständigt. I sökandet efter en biologisk förklaring, där vissa egenskaper och kroppsliga attribut sannolikt spelar betydligt större roll än andra, har jag utgått ifrån begreppet hög social status (äv. högstatus).
Storjuktan ? Rekonstruktion av ett sekels kvicksilverbelastning. : En undersökning av kvicksilverkoncentrationer i daterat bottensediment.
The aim of this study was to examine the current and historic mercury(Hg) load of the lake Storjuktan due to its recent exposure to a local potential source of Hg in form of the Sulphide mine Blaikengruvan(2006) and an earlier potential sources of Hg-load, the damming of the lake(1960s). Sediments were extracted using a HTH-sampler, freeze-dried, and analyzed for tot-Hg, LOI and activity of 210Pb and compared to samples extracted prior to the opening of the mine(2006). Constant initial concentration (CIC)-dating model was used for dating the samples. Low levels of Hg (100ng/g) were found throughout the lakes sediment. The highest levels of Hg(220ng/g) was detected at a depth of 4-5cm dating back to the mid 1970:s, suggesting that increased levels of atmospheric Hg rather than damming of the lake has caused the increase of Hg.
Bärare av mat : Arbetsfördelning och könsskillnader i restaurangbranschen utifrån ett genusperspektiv

The study is inspired by a discourse analysis perspective complemented by constructivist and critical pragmatic theory. Interviews were conducted in two focus groups with seven participants in total. The analysis is divided into four sections which answer six discourse analytical questions using the interview material.
Behöver vi en förändring? : olika perspektiv på hållbart jordbruk
Debatten om ekologisk kontra konventionell odling har blossat upp allt mer, förespråkare från båda synsätt har sagt sitt genom slagfärdiga debattartiklar och diskussionen har sedan fortsatt vid middagsborden runt om i landet.
Denna kandidatuppsats i ämnet landsbygdsutveckling syftar till att undersöka vilka drivkrafter som kan ligga bakom olika aktörers engagemang i jordbruksfrågor och hur de ser på vad som är en hållbar livsmedelsproduktion. Uppsatsen syftar även till att utforska hur informanterna framställer sig själva och andra aktörer i debatten som förts kring ekologisk kontra konventionell odling.
Vem bär enligt informanterna ansvaret för jordbrukets utveckling? Behövs en radikal omställning i hela livsmedelsproduktionen för att nå mer hållbarhet eller räcker det med att enbart göra små justeringar? Det empiriska materialet består till största del av fyra informanters syn på dessa och liknande frågor. Detta material har sedan analyserats med inspiration från Erving Goffmans teori om intryckskontroll och Ulrich Becks teori om risksamhället..
Barn- och ungdomars uppfattning om sin övervikt och fetma som ett problem samt skillnader i aktivitetsnivån hos barn- och ungdomar beroende på deras sociala familjesituation
BackgroundIncreased prevalence of obesity in children- and young adults and risk for diseases related to obesity will increase the burden on medical care. It is important to identify early risk factors that can be noticed by nurses in the daily work.AimThe aim was to investigate whether children- and young adults themselves perceive overweight as a problem and if there was a difference in the measured activity levels between overweight children- and young adults in families with different socio-economic family status.Method descriptionExisting survey from the Obesity Centre at the Akademiska Sjukhuset were examined together with the results from an accelerometer, where children- and young adults activity was recorded, compared to their perception of how active they were. The results were compared using a statistical software program and compiled with descriptive and non-parametric statistics.ResultsThe results do suggest that the majority of children- and young adults experiencing excessive weight have a problem in their everyday lives. Nearly half overestimate themselves as more active than what the actual measurements with accelerometer demonstrated. Much time is spent in front of the TV and computers.

Speciallärare eller specialpedagog? En studie om speciallärares/specialpedagogers syn på sin utbildning och yrkesroll inom särskolan
In 1990 the education training program for teachers working with children with special needs was changed. One major difference in the new program compared with the former one is that the specialized teacher is now mainly supposed to supervise teachers instead of teaching pupils who have learning difficulties. The aim of this qualitative interview study has been to find out what the specialized teachers think about there education, and how this could influence children with cognitive disabilities in special schools. I have interviewed six teachers who specialized in teaching pupils with cognitive disabilities. Three of them where educated prior to 1990 and the others were educated after 1990.
VARN Ett nätverksbaserat 2D-actionmultiplayerspel skrivet i Java.
VARN A network multiplayer 2D action game written in Java. All games that support any form of play across networks is in one way or another affected by the delay, or "ping", that occurs from the time it takes for information to travel over the wires. Not only does it take time, it varies depending on how far away the connected partner is and the current status of the network you are on. Through the years a lot of different methods have been developed to combat these delays. I have reviewed some of these methods and implemented a synchronization system in Java meant to be used in online action multiplayer games..
Grön Flagg : En kvalitativ studie kring barns delaktighet i de tre dimensionerna i hållbar utveckling
It is important to work with economic, social and ecological dimensions in order to reach sustainable development. Furthermore, these dimensions are supposed to work opon together. Green Flag´s aim is to process these dimensions in the thematic work in preschool, where children are involved. The aim of this study is to find out how certificated Green flag preschools work with the three dimensions in the education of sustainable development practically and how the children participate in this work. I have used a qualitative semi-structured interview to find out preschool teachers´ thoughts and opinions about how they work with sustainable development and how they make the children involved.
Flygbildsanalys av trädskiktets status efter brand : en metodstudie
During the past years fire has been identified as an important factor for nature conservation in the forest landscape. To accurately quantify the size of a burnt area is obviously important, but also to quantify the degree of fire damage to the tree canopy. Such data are important for assessing the conservation value, and to support planning and management of the burned area in the future.
I have examined how to estimate the status of tree crowns after fire from interpretation of aerial photographs. This is possible because fire changes the structure of tree crowns and this influences the colours in aerial photographs by spectral reflection.
Included in the study are four areas, three of which burned in 2005 and one in 2006.
Managing urban development : A case study of urban forest?s sense ofplace in Hammarbyskogen, Stockholm
Due to the growing population in Stockholm, some of the urban green areas are beingsubjected to exploitation. Hammarbyskogen is an urban forest in the south of Stockholm andis an example of a green area that is planned to be transformed into an urban environment.This paper investigates key qualities and values of an urban forest of Hammarbyskogenvalued by local inhabitants of the neighbourhoods of Hammarbyhöjden and Björkhagen in thesouth of Stockholm. In addition to that, the study seeks to investigate people?s perception ofthe planned development of the forest as well as investigate how these perceptions andqualities are being incorporated into the process of neighbourhood development.Using text analysis, interviews and discussion forums, findings have been made showing thatthe local inhabitants value the urban forest mostly for its ecological and recreational qualities.Regarding perception of the change, people are either positive or negative to the developmentwhich can be explained by people?s experienced sense of place and place attachment of thearea and the forest itself. The study has also shown that the urban planners rely on localinhabitants? view, as well as on expert knowledge during the process of planning.The results of the study contributes to a better understanding of why and for what purposesurban forests are important for the city dwellers..

Characteristics of Swedish gilts at service and producers? opinions about gilt production
In Sweden, selection for leanness in pigs has been going on for almost a century. This sometimes results in gilts and sows being too lean and consequently in a risk for reduced reproduction and health status. The Swedish recommendation includes that gilts should be mated after seven months of age, after one documented oestrus, at 120-140kg live weight and with a backfat thickness of 16-20mm. Five gilt producing herds were visited and records of age, heart girth (for weight estimation), body condition (visual estimation), backfat thickness and exterior were made. The same records were also taken in four gilt buying herds on newly purchased gilts.
Psykisk ohälsa bland barn och ungdomar i socialtjänstens öppenvård. : En kvantitativ studie om psykisk ohälsa, kön och socioekonomi i Södermalm och Rinkeby-Kista utförd med ?the Strengths and Difficulties Questionnaire?(SDQ)
The aim of this quantitative study is to describe the prevalence of mental health problems within the group of children and adolescents who receive support from two in home care units within the social services of Rinkeby-Kista and Södermalm stadsdelsförvaltning in Stockholm. Another purpose is to examine whether socioeconomic background and/or gender are associated with the prevalence of poor mental health, or mental health problems of a specific kind, in the studied population. Mental health is measured with the SDQ, a behavioral screening questionnaire that is widely used in Sweden and internationally. The study is based on data collected by the two units, which routinely screen children and adolescents with the SDQ. The main results of this study indicate that mental health problems are common in the studied population.
