1800-talets mediesystem
- 2010
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- Mediehistoria skrivs ofta utifrån ett medium i taget. Den här boken argumenterar istället för att historiens medier utvecklats tillsammans.Nya former, tekniker och praktiker har interagerat med gamla, innehåll har cirkulerat medierna emellan och rader av aktörer har aktivt relaterat till en helhet av uttrycksformer. Denna helhet var konturfast på ett vis som gör det befogat att tala om ett historiskt mediesystem: summan av en viss tids medier och deras inbäddning i sociala, politiska och ekonomiska villkor. I ett antal delstudier prövar boken möjligheterna att på närgången empirisk nivå undersöka 1800-talets mediesystem.

7:e Nordiska Forskarsymposiet i Turism 1998
- 1999
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- Nordiska Forskarsymposiet i Turism genomförs årligen. ETOUR stod som värd för 1998 års symposium som hölls i Åre i början av december. ETOUR har sammanställt konferensrapporten som innehåller de uppsatser som presenterades under symposiet. Deltagande forskare representerar olika perspektiv av turism, vilket gör att rapporten ger en bred översikt över nordisk turismforskning. Uppsatserna behandlar bland annat attraktioner, evenemang, destinationsutveckling, framtidens resande och attityder gentemot turism. Läsaren får en aktuell belysning av turistiska fenomen i denna rapport.

Deliverable 2.2 Possible market strategies for one stop shops of renovation of single family house. : Report prepared for Nordic Innovation Centre
- 2012
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The document describes examples of missions, visions and strategies based on the potentialpiloting models defined in report 3.2. It is based on status of interest amongst thestakeholders, and the information, figures and challenges which were discussed in the reportD 2.1 Stakeholder interests. The different service models will request different missionsdepending on the stakeholder in charge of the model. Also visions and strategies could bedifferent depending on the composition of services (core business) offered within each pilot aswell as the additional services offered by sub suppliers and the network connected to the pilot.In the report D2.1 Stakeholders interests, the following 5 different piloting models aresuggested:Type 1 Joint venture of industry, retailers and contractorsType 2 Joint venture of construction/renovation, industry and architect/engineering companiesType 3 Complementary businesses expand their business into renovationType 4 Joint venture of type house producer, bank and home owner associationType 5 Energy/building consultant, real estate agent and financing institutions, e.g. bankIn this report we have described mission, vision and market strategies for 4 existing orproposed models; The Project Manager by Bolig Enøk, from Norway (type 1), ENRA concept(type 2) and K-Rauta & Rautia (type 3) from Finland, and ProjectLavenergi (type 2) fromDenmark. Cleantech by Dong Energy (type 3) from Denmark is also addressed, but notdescribed in detail. As there is no concrete examples representing two of the models fromD2.1 (types 4 and 5), we have made a theoretical exercise in developing mission, vision andmarket strategies for type 5 model, while type 4 is not handled.It may be concluded that there are commercial actors in different parts of the value chainwhich see an opportunity in developing different approaches of “one stop shops” for energyefficient holistic renovations. The concepts are still in a development phase and differ inrespect to how they are organised (as supply side). We may say that the pilots in the differentcountries also find inspiration from each other through this research project. Due to thecomplexity of a holistic renovation project, it is a prerequisite with good partnerships even inthe development phase. In all identified models there is however one main actor taking thelead and ownership to the business model.Independent of the business model the responsible company needs to make some strategicchoices. The starting point is the SWOT analysis which sums up all major challenges for therespective business model. How the strategies should be developed is described in this report.Although the main target group for this report is companies seeing an interest in developingbusiness models for renovation, we found some important issues identified in the SWOTanalysis which the authorities may influence including lack of interest in the market (need ofmore public attention through holistic campaigns), fragmented solutions (stop subsidisingsingle measures without a holistic plan), serious vs unserious companies (need of certificationsystems to build credibility), cost focus leads to limited renovation (need of subventionschemes for holistic retrofitting including tax deduction measures) and finally lack incompetence within companies (need of support to training and collaboration acrosscompanies).

Drivers of snag fall rates in Fennoscandian boreal forests

Tidskriftsartikel (refereegranskat)abstract
- Persistence of standing dead trees (snags) is an important determinant for their role for biodiversity and dead wood associated carbon fluxes. How fast snags fall varies widely among species and regions and is further influenced by a variety of stand- and tree-level factors. However, our understanding of this variation is fragmentary at best, partly due to lack of empirical data. Here, we took advantage of the accruing time series of snag observations in the Finnish, Norwegian and Swedish National Forest Inventories that have been followed in these programs since the mid-1990s. We first harmonized observations from slightly different inventory protocols and then, using this harmonized dataset of ca. 43,000 observations that had a consistent 5-year census interval, we modelled the probability of snags of the main boreal tree species Pinus sylvestris, Picea abies and Betula spp. falling, as a function of tree- and stand-level variables, using Bayesian logistic regression modelling. The models were moderately good at predicting snags remaining standing or falling, with a correct classification rate ranging from 68% to 75% among species. In general, snag persistence increased with tree size and climatic wetness, and decreased with temperature sum, advancing stage of decay, site productivity and disturbance intensity (mainly harvesting). Synthesis and applications: The effect of harvesting demonstrates that an efficient avenue to increase the amount of snags in managed forests is protecting them during silvicultural operations. In the warmer future, negative relationship between snag persistence and temperature suggests decreasing the time snags remain standing and hence decreasing habitat availability for associated species. As decomposition rates generally increase after fall, decreasing snag persistence also implies substantially faster release of carbon from dead wood.
