Bilden av Afrika och dess historia : en diskursanalytisk studie av ett biblioteks böcker om Afrikas historia, utifrån omslag, baksides- och innersidestexter
The purpose of this master's thesis is to examine how a Swedish public library's collection of books on African history looks like, who the writers are and how Africa and its history areportrayed. The focus of the analysis is on the front and back covers and in some cases on theinformation texts inside the books. The chosen library is the city library of Umeå. The 15books examined were found on the shelf classified as Kp ? the classification for African history according to the Swedish SAB-classification system.
Predation av sandräka (Crangon crangon) på juvenil piggvar (Psetta maxima) och juvenol skrubbskädda (Platichtys flesus) : betydelse av yngelstorlek för överlevnad hos piggvar och skrubbskädda efter bottenfällning
Turbot (Psetta maxima) and flounder (Platichthys flesus) are two species of flatfish both having their nursery areas around the shores of Gotland in the Baltic Sea. The common brown shrimp (Crangon crangon) is a known predator on newly settled plaice (Pleuronectes platessa) in the North Sea area and is also found in the Baltic Sea. Experiments were carried out to see if the brown shrimp is predating on juvenile turbot and flounder, and if so on which sizes, and if the brown shrimp prefers any of the flatfish species, and also to see if there is a difference between day and night in density of the shrimp, i.e. when the fish might be subjected to predation. The results showed that predation decreased with size for both turbot and flounder.
A comparison of commercial scent lures in attracting Raccoon dogs (Nyctereutes procyonoides)
The invasive species raccoon dog (Nyctereutes procyonoides) is currently under establishment Sweden and it is vital to discover invading individuals to prevent colonization. The use of wildlife cameras to discover dispersing raccoon dogs have been implemented in the north-European raccoon dog management program. In this study, I test the ability of four commercially available scent lures to attract raccoon dogs to camera stations. The study was conducted in the Åland Islands where raccoon dogs are abundant and the results could improve the effectiveness of the camera stations used in the program. I used 12 sites with five camera stations in each and tested the four lures and one control with no lure in each site.
En åkattraktion till det förflutna : att bruka det förflutna för en upplevelse i samtiden
This essay discusses the use of history, and primarily how the current Swedish society perceives and uses the Viking age. The analysis is based on a literature study as well as a case study of the planned theme park in Fullerö north of Uppsala, Sweden. The aim of the essay is to understand the regional debate which arose in media regarding the planning of Fullerö Park and how it reflects the contemporary use of history. Research about the use of history has become increasingly common in recent years and deals with how history is actively being used in society in order to meet its existing needs. These needs varies among different groups and individuals and results in a multitude of usages, where the interests of the different actors may be contradictory.
Jämförelse mellan sådd och naturlig föryngring av tall i Härjedalen
The purpose of this study was to compare naturally regenerated Scots pine (Pinus sylvestris (L.)) against seeded Scots pine in terms of benefits and differences. An inventory was performed at a number of different sites, 4 ? 6 years after soil scarification and data on the number of new established plants, their height growth as well as ground-line diameter was collected. Information about site conditions such as altitude, quarter exposure and frost risk was also collected. A review of previous studies was conducted in addition to the field study.

NAFTA-avtalets inverkan på den mexikanska jordbrukssektorn
Har NAFTA-avtalet (North American Free Trade Agreement) som 1994 ingicks mellan Mexiko, USA och Kanada, haft de effekter på den mexikanska jordbrukssektorn, speciellt dess majssektor, som kan förväntas i enlighet med nationalekonomisk teori? Detta är den huvudsakliga forskningsfrågan som denna uppsats försöker undersöka och besvara. Min slutsats är att i fråga om Mexiko är svaret i huvudsak beroende på vilka producenter man väljer att studera. När gäller dess majssektor är effekterna av NAFTA på de konstbevattnade producenterna, företrädesvis i norra Mexiko, mer eller mindre i linje med vad som kan förväntas, medan effekterna på de regnbevattnade producenterna företrädesvis i södra Mexiko ej följer det förväntade mönstret. I en fortsatt analys av NAFTA-avtalets konsekvenser, framstår behovet av statliga interventioner mycket tydligt.
Vad är ett bra reklamspel?
Reklamspel är ett verktyg inom reklambranschen, en bransch som undergått stor förändring under senare års digitala utveckling. Denna förändring uppmanar ständigt till bredare kunskap och högre förståelse hos både skapare och användare.Syftet med uppsatsen var att påbörja ett ramverk för skapandet av ?bra? reklamspel. För det krävdes att ordet ?bra? definierades och kunde förstås så att även diskussionen kring spel och reklam förbättrades.Det material som uppsatsen grundats i kommer från en två månader lång praktik där ett reklamspel producerades och från det designdokument som digitalbyrån North Kingdom lämnade efter sitt reklamspel, The Coke Zero Game.Med kvalitativa metoder samlades resultat in och jämfördes mot en teoretiskgrund byggd på kunskap inom marknadsföring, interaktions- och speldesign, användbarhet och uttryck ofta använda i spelsammanhang.
Utsläpp av växthusgaser under islossning i små boreala sjöar
Freshwater ecosystems have long been neglected as an important part of the global carbon cycle. However, research shows that most of the world?s lakes are net-heterotrophic and consequently emitters of greenhouse gases to the atmosphere. In many boreal and north-temperate lakes, most of the yearly emissions usually occur in spring, shortly after ice-thaw. The aim of this study was to quantify the flux of carbon dioxide (CO2) and methane (CH4) in three boreal lakes, during this annual event.
Sjunkande pH i Västerbottens humuslager : en kvantitativ analys
Acidification is a central concept in the environmental debate. The effect of acidification of the soil is a matter of a decreasing amount of cations and thereby a decreasing ability to resist a supply of hydrogen ions to the soil. Acidification has gradually increased in the O horizon in Västerbotten over a 30-year period from the 1970th to the 1990th. The aim of this study was from inventories of The Swedish National Forest Soil Survey and The Swedish National Forest Inventory explain and quantify the acidification that has occurred in the O horizon of two regions in the north of Sweden. Data from SMHI, The Swedish Meteorological and Hydrological Institute, has also been used.
Ett komplext hemland : En kvalitativ studie av televisionsprogrammet Homeland
After 9/11 and the following War on Terror, Muslims are often understood as global enemies. However, the idea of an international, Islamic enemy is in some circumstances criticized, not least after the actions of Anders Behring Breivik in Norway in 2011.This study analyses the North American, Emmy Award-winning television series Homeland. It centres on the War on Terror and the following social and political climate, and there are opposing understandings regarding how religion and ethnicity are portrayed in the series. Accordingly, the aim of this study is to analyse how such aspects are constructed in the series. A text analysis is used methodologically and the theoretical perspective contents of Semiotics, Eurocentrism and Orientalism in general, and Islamophobic themes in particular.This study shows that in Homeland, the portrayal of heroes and enemies plus good and evil is complex.
Vindkraft och rennäring
The Swedish Parliament has decided to increase the share of electricity produced by wind power. The same parliament has decided that the Sami have the right to herd reindeer over 50% of the country's land area. In this literature review the potential impact wind power development and associated infrastructure may have on reindeer husbandry conditions are examined.
The unique physiology of the reindeer enables it to live out of grazing in the arctic climate in the north of Sweden. For reindeer husbandry to be long-term productive and sustainable, it is important that there is enough land for grazing. The research available on how reindeer are disturbed by human activities such as roads, mines, hikers, etc., clearly indicates that the reindeer avoids areas close to such disturbance.
Site fidelity of a migratory species towards its annual range
Site fidelity, the behaviour of animals to return to areas where they have been before is a common trait in many species. The Scandinavian moose is known to show fidelity to its range, but to what extent, is little known. The landscape in Sweden changes in a predictable and unpredictable way and hence gives the opportunity to test the existence of fidelity. I used the kernel Brownian bridge method to estimate the home ranges of individual moose over consecutive years and estimated the overlap at the home range level. I also used Euclidian distance to look on calving site fidelity.
Marknadsföring via bibliotekets webbplats
The aim of this study is to investigate the public libraries use of their websites in their marketing. Our study is based on the websites of 60 public libraries. The libraries are chosen because of their geographical location in three different provinces? Skåne in the south, Östergötland in the middle and Norrbotten in the north. These three choices enable us to cover densely as well as thinly populated areas, the agricultural district, the woodland and cities of various sizes.
Kartläggning av socialtjänstens arbete med våld i nära relationer : - en studie av sju kommuner i nordvästra Stockholm
Intimate partner violence is a problem which is increasingly drawing attention in society. The authority responsible for providing care and support to victims of intimate partner violence and their children is the social services. The purpose of this study was to show how social workers deal with intimate partner violence and to create a description of how this work is currently carried out in seven municipalities in the north-west of Stockholm. This was done through a quantitative survey including all investigating social workers in the municipalities concerned. The results were analysed with concepts from organizational theory.
