Genomgång av kemikalieförteckning som exempel på uppströmsarbete : en identifiering av utfasningsämnen i spillvattnet

Benthic invertebrates play important roles as feeding resources for many organisms in different food webs. Shifts in predation of these organisms can generate cascading effects and potentially lead to the disappearance of one or more species from a site. Cascading effects can bring impacts to organisms who aren?t even directly involved, why studies in this field are important for understanding sudden changes in ecosystems. I examined the predation from fish and waterfowl on benthic invertebrates in the shallow and eutrophic Lake Tåkern in the plains of Östergötland County, southern Sweden.

Kan förändringar i bottenfaunan påvisas två år efter en bäckrestaurering?

The aim of this work is to analyze if a change in the benthic community can be detected two years after a restoration of a small stream. The samples were taken in a small stream at Tinnerö Eklandskap just south of Linköping. In addition to the restored area, two reference sites upstream and downstream of the restored area were sampled to compare to the restored site. The method used for sampling of benthic fauna in the stream was kick sampling. ASPT, Berger-Parker and Renkonen-indices were used to find out if there was any difference between the reference areas and the restored area.

Online Brand Community in Action. A Constitutive netnography: Advancing a Wholesome Ethnomethodological Perspective on Brand Community

This thesis advances an explicit, consequent, and wholesome ethnomethodological perspective on brand community. It recognizes brand community as a social problem ? something to be continuously solved and achieved. The two main perceivably stable features of the Nikonian community are (1) practical usefulness and (2) the social link. The authors suggest that both features are constantly accomplished through three types of aggregate behaviour (1) lurking, (2) ordinary membership, and (3) community citizenship behaviour (CCB).

Affärsmodellen kring ett Community

Abstrakt Titel: Affärsmodellen kring ett Community Författare: Gezim Pirku & Kreshnik Goga Handledare: Gunnar Ågren Institution: Managementhögskolan, Blekinge Tekniska Högskola Kurs: Kandidatarbete i företagsekonomi, 10 poäng Syfte: Syftet med vårt arbete är först och främst att undersöka vad aktuell teori säger om affärsmodeller för traditionella respektive Community företag. Sedan skall vi bestämma om teorier av ett Community företag stämmer med ett verkligt Community. Metod: Kvalitativ datainsamling för den teoretiska delen och frågeformulär för den empiriska undersökningen. Slutsats: Vi fann att skillnaderna i vad teorierna säger om Communitys och ett riktigt Community inte är stora utan man tar till sig de strategier som teorierna beskriver..

Pensiostorm.se : En community med fokus på slutanvändaren

Idén med att skapa en community för pensionärer föddes under hösten 2005 av dåvarande generaldirektören vid Statens pensionsverk (SPV). Denne kontaktade Mittuniversitetet i Sundsvall för att skapa en lättan-vänd och syftesuppfyllande community för pensionärer. Min uppgift har varit att utforma denna community med fokus på slutanvändaren. Uppgiften utgick från en kravanalys som tagits fram av forskare vid Mittuniversitet. Utifrån kravanalysen har ett användargränssnitt skapats enligt standarder för webbutveckling för dem som har ett funktionshinder.
