Human existence and welfare depend on functional ecosystems. Ecosystems are critical to sustain life-support services for human well-being. One method that visualizes that humanity requires ecosystem services for resource consumption and assimilation of produced waste is ecological footprints. This study focuses on the ecosystem service carbon sequestering. A quantification of this ecosystem service showed the potential for accumulation of carbon in different ecosystems in Stockholm and Norrbotten County for the years of 1995 and 2004.

The business potential of software defined radio (SDR) technology is studied by evaluating whether or not its characteristics correspond to those particular to a disruptive technology. The maturity of the SDR technology concept is illuminated by analyzing the opinions and perspectives of a selection of representatives for different stakeholders in the wireless communications market. Characteristics as, for example, the degree of consensus about the utility of SDR technology and the awareness of features and limitations are studied by application of the theory of technological frames. This theory helps us understand how and when technology evolution takes place. Finally we describe the value network structures of some potentially viable application areas for SDR and suggest some possible business opportunities based on SDR technology.This thesis is carried out as a case study and the research data is obtained from secondary sources, such as literature and Internet publications as well as interviews with people well experienced in the field of wireless communications.

Studien handlar om förklaringar av förändring hos några av de forskare med historiematerialistiska inslag som hade en framträdande roll på 1970- och 1980-talen. Övergången från feodalism till kapitalism och industriarbetarens roll i arbetsprocessen var två fält som var på tapeten under denna period, som kan härledas ur den radikala 68-rörelsen. Med sociologen Piotr Sztompkas systemmodell som teoretisk ram undersöktes Christer Winbergs, Maths Isacsons, Anders Floréns, Lars Olssons och Lars Ekdahls avhandlingar samt ett verk av Alf Johansson. Syftet var att utforska de teoretiska utgångspunkterna och slutsatserna i alstren. Svar söktes på vilka drivkrafter författarna anger till förändringarna i sitt material; var i systemet på mikro-, meso- eller makronivå dessa förändringar inträffar; och vad förändringarna leder till.

The life cycle of the anadromous Atlantic salmon (Salmo salar) can span large geographic, political, and socio-economic boundaries. Management strategies and regulations that only concentrate on small spatial scales often overlook larger basin-wide problems, especially relating to post-spawn seaward migration. In this master thesis one entire migration cycle of wild adult Atlantic salmon in the unregulated northern Swedish river Vindelälven was monitored by radio-telemetry tracking during upstream spawning migration and downstream seaward migration back to the Baltic Sea. The effect of ladder passage variables (time to pass, total time in the ladder, passage day over the ladder) at a fish ladder downstream in the river Umeälven, as well as fish size, were evaluated to determine if differences in upstream migration distance in the river Vindelälven could be observed. Ladder passage variables did not affect migration distance, but size exhibited a negative relationship to migration distance.

The transformation within the swedish infrastructure has been a slow process from thebeginning of time. For almost a decade, the traditional form of contracting regardingbuildings and foremost infrastructure has evolved contracting involving the owner to definethe outcome of the product, regardless involvement from the supposed contractor. As forthe swedish market, the traditional design-bid-build (DBB) have been the primary choice ofcontracting. Although changes have been made over time regarding contracting formswithin the road administration, the railway sector has not improved or justified changesregarding choice of contracting, they have conducted same contracting relationshipsbetween them and the contractor.This bachelor thesis, conducted at the Swedish railway administration with supervision ofprofessor Kristian Widén at Lunds University, explores the forces behind the new era ofcontracting within the railway administration. This bachelor thesis focuses mainly oncontracting regarding design-build-operate-main (DBOM), the new contracting formulabetween the owner and the contractor.

In the wake of a heightened interest in the Swedish Middle Ages, the need for knowledge has increased as well. The Swedish Middle Ages was an era when the country truly began to grow closer to the European sphere of culture. The forces behind this transformation are largely to be sought among the social elite, the budding aristocracy of Sweden. The process of becoming ?Europeans? brought with it great changes to Sweden, not the least in terms of the political arena.

Samhället förändras kontinuerligt. För att människor ska må bra i ett föränderligt arbetsliv behöver de uppleva att de har möjlighet att vara delaktiga kring det som berör dem. Ett hälsofrämjande arbetsliv är inte bara gynnsamt för individen, det bidrar även till hållbar tillväxt i samhället.  Organisationer strävar efter att utveckla sina verksamheter, vilket i forskning ofta diskuteras utifrån ekonomiska perspektiv. Att i kontrast till det ekonomiska perspektivet studera organisationer utifrån ett pedagogiskt perspektiv är föreliggande undersöknings fokus. Perspektivet syftar till att studera mellanmänskliga påverkans- och förändringsprocesser samt dessas förutsättningar inom organisationer.

Metso Paper är en global marknadsledande leverantör av utrustning och tillverkningslinjer för massa- och pappersindustrin. Detta examensarbete är utfört vid Metso Service Sundsvall ett dotterbolag till Metso Paper. Metso Service Sundsvall, ansvarar för servicen på eftermarknaden för den installerade maskinbasen av kemisk och mekanisk massateknologi hos Metso Papers kunder. Massa- och pappersindustrin har under de senaste åren genomgått en transformation som kommer att bli allt mer tydlig i framtiden. Vinsterna för företagen inom massa- och pappersindustrin har sjunkit till följd av bland annat fallande världsmarknadspriser.

Samhället har gått från att vara monokulturellt till att bli mångkulturellt, vilket har lett till pedagogiska utmaningar för skolan. Enligt skolans styrdokument ska alla elever ges lika studie- och utbildningsmöjligheter, men elever med utländsk bakgrund missgynnas. Detta blir tydligt av statistik som visar att var fjärde elev med utländsk bakgrund går ut grundskolan utan grundläggande behörighet, vilket kan jämföras med var tionde elev med svensk bakgrund. Faktorerna är sammansatta, men denna studie inriktas främst på språkliga faktorer. Arbetet utgår ifrån ett socio- och interkulturellt perspektiv på lärande, och berör även forskning om språkutveckling.

Projektet har genomförts i samarbete med Lokalförvaltningen, Göteborgs Stad.Eftersom behovet av lokaler i en stad förändras över tid efterfrågas en byggnad som kan användas till flera olika ändamål under dess bruksperiod. Ombyggnation av befintliga byggnader kan bli kostsamma och tidskrävande eftersom bärande komponenter eller fasta installationer ofta måste flyttas eller bytas ut. En flexibel byggnad som redan vid uppförandet förbereds för ombyggnation kan enkelt anpassas och användas till flera olika verksamheter. Att bygga mer effektivt och flexibelt minskar kostnader och bidrar till ett mer hållbart byggande. Syftet med arbetet var att ta fram en byggnad som genom enklare omställningsarbeten i byggnadens invändiga utseende kan fungera för tre olika verksamheter.
