Fick algblomningen i Östersjön 2005 några ekonomiska effekter? : Fallet turistnäringen på Gotland

Algal bloom is a naturally occurring phenomenon and occurs in all waters around the world but in recent years, algal bloom in the Baltic Sea has become more massive and more widely spread. When an algal bloom negative effects on the seawater quality, it may have an impact on tourism in the Baltic Sea. The aim of this thesis is to study, through a survey based on a production function approach, whether an environmental change as algal blooms, influenced the Gotland tourist accommodation industry and their "production of attractive overnight? in the summer of 2005. The results show that algal blooms did not have a great impact on companies ?production of attractive accommodations".

Musiken i Bolibompa. : Utveckling, utrymme och pedagogiska funktioner.

With inspiration from Bitzers situational analysis a phenomenografic method has been used, influenced by Brown & Levinsons´s theory of politeness, to find perceptions concerning constraints (in Bitzer´s sense in his model of the rhetorical situation) in Internet-based communication. Based on three qualitative interviews, this essay has found that the perceptions are closely linked to views of what constitutes formal and informal contexts, varying due to the gender or age of the informant. Netspeak is not considered appropriate, with some exceptions, in any formal situation. However, the perceptions regarding decorum in informal situations differ in nature, based mainly on what kinds of associations and connotations are produced by elements found in netspeak. Since perceptions regarding informal situations vary, there is a large risk of misunderstanding, which this essay aims to survey..

Predicting spawning bed erosion and longevity : a case study in tributaries to river Vindelälven, northern Sweden

Timber floating operations in Scandinavia during the 19th and 20th centuries has contributed to severe negative impacts on riverine ecosystems. Increase in water velocity and lack of stream bed heterogeneity as a result of stream channelization lead to increased bed load transport. Since availability and recruitment of new suitable spawning substrate in Scandinavian watercourses is sparse, spawning habitats for salmonids has become a scarce commodity. Lately, increasingly more attention has been given to the recreation and improvement of brown trout (Salmo trutta) spawning habitats in restoration projects. While much of the research on spawning habitat has been focused on evaluation of the influence that the constructed spawning grounds have on fish populations, few studies have been conducted to evaluate the persistence of these constructions over time. I evaluate erosion of constructed spawning beds as an effect of sediment transport attributable to water discharge.

Om behovet av ett avrinningsområdesanpassat skogsbruk

The Swedish forest have about 100 000 km of watercourses and it?s an important structure in Swedish landscapes and catchments. In some of the watercourses lives spieces like the freshwater pearl mussel (Margaritifera margaritifera) and brown trout (Salmo trutta) which both are sensitive for inteference from the forestry. The new EU water framework directive has a goal that all surface water will have high or good ecological- and good chemical status at latest by the 22nd December of 2015. The study has been made in the catchment of Håltjärnsbäcken and it is from a national perspective one of the most valuable streams in Sweden and which also have been included in a LIFE-project. The catchment is situated within the Eco-park of Malingsbo-Kloten and managed by Sveaskog AB.

Stowe: en landskapspark av betydelse

Målet med uppsatsen var att utforska och resonera kring hur en parkanläggning, i detta fall Stowe Landscape Gardens i Buckinghamshire, England, kan få en viss betydelse och värderas högt av eftervärlden. Frågorna som uppsatsen utgått från är: - Vad är Stowe? - Hur beskrivs Stowe? - Vilken betydelse har Stowe och varför? Stowe verkar vara betydelsefull för landskapsarkitekter att känna till, och uppsatsen kan komma att utgöra ett underlag för en diskussion kring hur olika anläggningar framställs i trädgårdshistorien, och hur man som landskapsarkitekt kan förhålla sig till det. Genom litteraturstudier och en intervju med Barry Smith, Head Gardener på Stowe, har en undersökning av hur Stowe omnämns i olika typer av litteratur genomförts, för att se hur Stowe representeras. Uppslagsverk, undervisningslitteratur för landskapsarkitekt-programmet på SLU Alnarp, litteratur från The National Trust (organisationen som äger och förvaltar Stowe idag1) och resonerande trädgårdskonstteori har utgjort underlags-material. Resultatet i tabellsammanställningen tyder på att Stowe har en stor betydelse i träd-gårdshistorien, eftersom den anses vara mycket tidstypisk för landskapsparkernas tids-period, med stöd av de studerade källorna.

The investigation is based on the students? comments on their peers? speech drafts and six qualitative interviews.

Ombyggnation, från sågverkslokal till restaurang. antonio ziakoulis

Pharmaceuticals that are found in marine ecosystems are a threatening environmental concern, which is known to harm both animal and plant life. One of the reasons for this problem is that the waste water treatment techniques are not optimized to clear waste water from its pharmaceuticals contain. In this master thesis four Swedish treatment wetlands were studied, and their ability to reduce numerous pharmaceuticals in waste water. The four treatment wetlands that were studied were those in Oxelösund, Trosa, Nynäshamn and Eskilstuna. Two ecotoxicological tests and chemical analysis were used.

Metodikstudie av trollingfisket i Vänern : Jämförelse av fångstrapportering mellan intervjuer och enkäter gjorda på trollingfiskare samt vädrets påverkan på ansträngning

There are five endemic populations of migratory Atlantic salmon (Salmo salar, Salmonidae) and brown trout (Salmo trutta, Salmonidae) remaining in Lake Vänern, whereof two are salmon and three are trout. There is one population of each species in Klarälven, also one of each in Gullspångsälven and there is a population of trout still remaining in Tidan River. Since the beginning of the 20th century endemic populations of salmon and trout have either vanished or declined dramatically due to the construction of hydropower in the rivers around the lake, and still today the future of the remaining populations remains uncertain. To manage salmonid fishes effectively more knowledge of their ecology throughout their different life-stages is needed. A large part of the Lake Vänern salmonoids lives are spent in the lake, where a mayor mortality factor is recreational fishing, especially angling.

Immersion och Tidsbegränsade Dialogval i Dataspel

Arbetet undersöker hur tidsbegränsning på dialogval i spel påverkar spels förmåga att skapa immersion. Immersionsbegreppet gås igenom och flertalet saker pekar på att tidsbegränsningen kan ha en effekt på spelarens immersionsnivå. Brown och Cairns (2004) beskriver exempelvis både uppmärksamhet och tid som centrala för immersion och en tidsbegränsning kan mycket väl tänkas påverka båda dessa faktorer. Douglas och Hargardon (2001) skriver också hur en tung bok generellt ger lägre immersion då läsaren måste stanna upp och tänka. En tidsbegränsning kan hindra spelaren från att stanna upp och tänka och därmed påverka immersionen.

It describes a non-linear project based on a process-orientated theory called Theory-U by Otto C. Scharmer (2009). The project aims to investigate the changing conditions of Stage Theatre and deals with non-linearity as phenomena.

Ingmar Bergman och musiken : En audiovisuell analys av Såsom i en spegel, Tystnaden, Persona och Vargtimmen

The research on Ingmar Bergman is comprehensive, however, there is one aspect of his artistry that has been regrettably neglected ? his use of music. Music always played a huge part in Bergman?s life, and it was also a great source of inspiration. The music was a structural component in the creating process and he often referred to his films as pieces of music and his actors as musical instruments.

Motivation, spel och kanji : Gameplay:s inverkan på motivationen i spel med syfte att lära ut kanji

Denna uppsats undersöker hur olika nivåer av gameplay i spel påverkar motivationen hos testpersoner som deltagit i en undersökning där de fått spela olika serious games framtagna med syfte att lära ut det japanska skriftsystemet kanji. Metoden för undersökningen är baserad på teorier och tidigare undersökningar av bland andra Owston, Wideman, Sinitskaya Ronda och Brown (2009), De Grove, Merchant och Van Looy (2009) och Csikszentmihalyi (1990).I undersökningen har 27 testpersoner fått testa tre olika spel med olika nivå av gameplay, och har sedan i ett frågeformulär fått redogöra för bland annat hur underhållande och utmanande de fann spelen.Resultatet av undersökningen är ickesignifikant, men visar ändå indikationer på att mer gameplay ger mer underhållning. Den största slutsatsen undersökningen ger är dock att olika varianter av gameplay är att föredra, då olika personer ofta har olika smak baserat på tidigare spelvana m.m..

Döden som social överlevnad. Keltiskt människooffer under järnåldern

This essay concerns the Celts during the Iron Age, and their ritual practice in human sacrifice. The method applied is an eclectic historic-critic reading of the few classical sources that exist together with archeological material and scholars conclusions of literal sources and archeological material. The hypothesis is that human sacrifice in the Celtic realm not is to be seen as a primitive act of violence, but that it filled a social function to preserve society and the Celtic way of life.The question this essay strives to answer is Which function/s do human sacrifice fill in a Celtic context during the Iron Age? The question is analysed with the aid of Radcliffe-Brown?s and Catherine Bell?s theories on ritual, as well as Malcolm Chapman?s postmodern ideas of the conception of the Celtic. The conclusion of the essay is that the prime functions of Celtic human sacrifice are to preserve society and the Celtic social way of life, combined with an aim to eliminate disturbing elements in that same society, such as crime and individuals who did not fit in to the social community..
