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.
Den ärvda utbildningen och det (o)fria valet? : En jämförande studie mellan fem olika program på Örebro universitet
The inherited education and the (un)free choice?- A comparative survey between five different programs on University of ÖrebroThe aim with this paper has been to examine and to report for different sociocultural background factors (class property, the parents' level of education, the parents' income) importance for the choice of type of education and to see if there is any differences between different university courses with respect to class property. Our issues were following:1. What/which sociocultural factors have had most importance for the choice of programs on universities?2.
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.
Karaktärisering, utvärdering och avsättning av Stena Metalls magnetiska fines
With a growing population on earth the amount of end-of-life vehicles (ELVs) and other scrap steel increases. The European Directive 2000/53/CE? requires a minimum of 95 % reuse and recovery and 85 % re-use and recycling no later than 1 January 2015, for end-of life vehicles. This imposes a need for more efficient recycling and recovery. Despite this shredder residue (SR) is commonly land filled.This report investigated the magnetic fines residue generated at Stena Metall shredder facility in Halmstad, Sweden.
Med vänlig hälsa
Syftet med denna studie är att belysa gymnasielärares syn på begreppet hälsa och hur de definierar hälsobegreppet inom ämnet idrott och hälsa. Vidare är syftet att undersöka på vilket sätt dessa lärare beskriver att de arbetar med hälsa i ämnet på gymnasiet utifrån kursplanen Idrott och hälsa 1. Studien utgår ifrån följande frågeställningar: Hur definierar lärare i idrott och hälsa begreppet hälsa? Hur beskriver lärare i idrott och hälsa begreppet hälsa inom ramen för idrott och hälsa? och Hur framställer lärare i idrott och hälsa att de arbetar med hälsa i sin undervisning utifrån kursplanen Idrott och hälsa 1?Kvalitativa intervjuer med lärare i idrott och hälsa på olika gymnasieskolor har använts som metod för att insamla data till undersökningen. Studien är en kandidatuppsats och är inte generaliserande för en större population.
Kvinnors rättigheter och icke-statliga Organisationer, a perfect match?
Since the Convention on the Elimination of All Forms of Discrimination against Women (CEDAW) was adopted in 1979 there has been evident progress in the area of women's rights in great parts of the world, although this progress is still foremost concentrated to the Westernhemisphere. In Argentina, the work with gender equality and women's rights set of strongly during the last decade. The country has ratified the Convention on the Elimination of All Forms of Discrimination against Women and the Inter-American Convention on the Prevention, Punishmentand Eradication of Violence against Women "Convention of Belem Do Para" but still women and girls are victims of structural discrimination and serious impunity of their rights on a daily basis.The current situation proves that the positive changes within the context of international and national law do not necessary reach out to the population to the same extent. In the light of the lacking popular involvement and knowledge of their rights, a different type of solution is desirable. Therefore it would be of interest to examinate the role of Non Governmental Organisations (NGO:s) when it comes to implementing human rights in the society and ?the every day life?.
"Fallbacks" - betydelsen av vandringstid för Atlantlax (Salmo salar L.) som faller nedströms vandringshinder
In Lake Vänern, Sweden, there is an endemic population of Atlantic salmon (Salmo salar L.) that lives its entire life in fresh water. The salmon is hindered from migrating to its natural spawning sites in the northern part of the River Klarälven by nine hydro-electric power plants. None of the hydro-electric power plants have fishways so that salmon migrating upstream or downstream may pass. In the current situation, the upward migrating salmon are caught in a fish trap at the most downstream located power plant in Forshaga. From there, the salmon are driven in a truck, past eight power plants and released a few kilometers upstream of the eighth power plant at Edsforsen.

Ekologisk hållbarhet i den fysiska planeringen, teori till handling :
I wrote this essay with the aim to explore, understand and get some insights into what it is that effects the possibilities to plan for ecological sustainability and make it happen.
There is no clear definition of sustainable development but world top meetings and reports have developed goals and strategies. I will present some of the theory at hand but most of this essay is based on six interviews with planners at local governments from around the country. Several of the local governments are using the goals issued by the state government by putting them into their large scale plans. During the interviews some obstacles were identified, like a lack of resourses, disadvantaging powerstruktures, conflicts with marketeconomy and simply different meenings about what ecological sustainability is in practice.
My method of getting information through interviews and documenting them by taking notes had, as all methods, it?s weakneses.
Engångshjältar - Hur myter och symboler konstruerar nationalism på Balkan
This thesis is about how nationalism is constructed from two competing groups, Kosovo Albanian and Serbs. Kosovo for Serbs is a deep symbolic value that continues to be a Serbian identification. This is one of the main reasons why no Serbian politician has the courage to give it up. On the other side of the coin we have the Kosovo Albanians that only settles for independence. To recognize the independence for Kosovo could jeopardize the security for the Serbian minority living in Kosovo.
Etnisk boendesegregation : En kvalitativ studie om etnisk boendesegregation i Nybro ur ett postkolonialt perspektiv
A refugee reception has been placed in Kungshall, one of Nybros residential areas. The area has a bad reputation and there are arguably prejudices about the area from the local population. I therefore want to investigate if an ethnic residential segregation exists in Kungshall, from a postcolonial perspective. The following research questions have been formulated: How do residents who doesn?t live in the refugee reception, look at ethnic residential segregation in Nybro? How has Kungshall changed since the refugee reception? Does a cultural racism exist in Kungshall? The study is a qualitative study using semi structured interviews of four people living in the residential area, a person who has moved out of the area and a person working on the housing corporation ?Nybro bostads AB?, who is one of the housing corporation responsible for the residential area Kungshall.
Vart sker besparingarna inom kommunens verksamheter?
I have worked with Bergum in different courses on the IntegratedConservation of Built Environments program and I thought it was a veryinteresting subject. This is the main reason why I chosen to write mybachelor paper about Bergum.In 1650s Bergum was situated on the border between Sweden and Norway,because of that it occurred some war conflicts.Today Bergum is a socioeconomic border and is situated in an areabetween the city?s concrete suburb and the countryside.The difference between the city?s concrete suburb and the countryside mayfeel like two different worlds, were the social contact is fractional.With this paper, I will indicate a countryside area on the boundary to the citythrough time and try to survey the building history. I will also try todemonstrate the socioeconomic differences between the areas.I will demonstrate Bergum history from prehistory to present time, were I willdiscuss the agriculture history, Vättlefjäll?s forest history and also thedeforestation and replanting.
Tonårsförälder eller förälder? : Hur professionella inom människovårdande organisationer uppfattar och jobbar med gravida tonåringar och tonåringar med barn.
Syftet med föreliggande studie var att studera huruvida intagna på en störrekriminalvårdsanstalt (klass A) i Mellansverige, skiljer sig i personlighetsdragen Samvetsgrannhet, Vänlighet, Extraversion, Emotionell Stabilitet och Öppenhet ijämförelse med två kontrollgrupper. Tidigare forskning har visat att kriminella personer ligger lägre i skalorna (faktorerna) som mäter Samvetsgrannhet och Vänlighet, i jämförelse med ostraffade individer (t.ex., Miller & Lynam, 2001). Den primära hypotesen var följaktligen att söka diskrepans mellan just Samvetsgrannhet och Vänlighet i enlighet med tidigare empiri. Studien genomfördes med ett självskattningsformulär som stödjer sig på en svensk översättning från Goldbergs (1992) International Personality Item Pool (IPIP)beträffande grundläggande personlighetskaraktärer. Studien utgjordes av intagna(n = 46) och två kontrollgrupper bestående av studenter (n = 32) samt vaktpersonal (n = 45) vid en klass A anstalt i Sverige.
Effektiv mätning av livskvalitet - Brunnsviken Brief Quality of Life Inventory (BBQ) : en psykometrisk utvärdering
Målet med Brunnsviken Brief Quality of Life Inventory (BBQ) är att skapa en kortfattad och lättadministrerad skattningsskala för självupplevd livskvalitet med goda psykometriska egenskaper vilken är gratis för alla att använda. I framtagningen av BBQ har data insamlad med Quality of Life Inventory (QOLI) i tidigare studier använts för att identifiera de livsområden med störst betydelse för självupplevd livskvalitet. I aktuell studie har normvärden tagits fram för den i studien ingående undersökningsgruppen bestående av 167 psykologistudenter. Studien har visat att BBQ har utmärkt reliabilitet (test-retest), 0,89. Vidare hade BBQ lika god validitet för undersökningsgruppen som QOLI.
