This thesis presents a new way of providing library users with reference services, namely chat (text based digital reference service in real time). Our research questions focus on the role of reference service, a comparison of chat reference to other reference forms, and the interest for real-time, digital reference. Our literature review covered the areas of digital reference and reference theory

Methods and equipment used for fighting forest fires are different from the ones used in urban fires. Generally, the wildfires are intense, require more resources and tend to spread rapidly. The effectiveness of different suppression techniques is difficult to evaluate since they depend on terrain, weather conditions and other varying factors over time and space. The current study focuses on the s

Tre grustag undersöktes i nordöstra Tyskland, Kreuzbruchhof, Fritscheshof och Spargelberg. Syftet var att rekonstruera den senaste glaciala aktiviteten i området. Tolkningarna och således rekonstruktionen grundar sig till största delen på sedimentologiska och strukturella undersökningar. Kreuzbruchhof består mestadels av glacifluviala sediment med undantag för några mindre diamikta enheter tolkadeThree gravel pits near Neubrandenburg, NE Germany, were investigated - Kreuzbruchhof, Spargelberg and Fritscheshof. The investigated gravel pits are situated in an undulating kame landscape 150 km south of the Baltic Sea. The aim of this study was to reconstruct the Late Weichselian history (e.g. deglaciation of the Pomeranian ice sheet) of the area. Reconstruction was based mainly on sedimentolog

The aim of this study was to examine the view of social service workers on the secondary housing market based upon their work with social investigations regarding people with a difficult substance abuse. The foundation of this study rests upon a phenomenon, which according to other scholars, occurs in the secondary housing market in Sweden. The secondary housing market consists of a multitude of h

Many construction companies have a construction service department but it is normally never the largest part of the company. Rather, the building services department has been seen as a fender to keep employees engaged when the economy’s been bad, with the result that no large investments have been put towards the service department. The logistics of the construction services business is different

Issue of study: A forecasted increase in energy demand and consumption, together with a decrease of existing oil and gas reserves, has led the oil and gas producers to new areas beyond the conventional oil and gas regions. The Arctic, an area mainly located north of the Arctic Circle, is believed to hold very large potential of the world’s yet-to-be discovered oil and gas reserves. In addition, th

The older people of tomorrow, today in an age between 50 and 64 years, are a key group at the Swedish housing market. This group are soon becoming one fifth of the Swedish population and the share of retired are going to increase with 22 percent (374 000 persons) among a ten-year period. Their choice of dwelling for the future will have great effects on the housing market. For the older caseload t

Realistic depictions of past land cover are needed to investigate prehistoric environmental changes, effects of anthropogenic deforestation, and long-term land cover-climate feedbacks. Observation-based reconstructions of past land cover are rare, and commonly used model-based reconstructions exhibit considerable differences. Recently, Pirzamanbein et al. (2018, 10.1016/j.spasta.2018.03.005, Spati

Identifying key molecular pathways and genes involved in the response to urban pollutants is an important step in furthering our understanding of the impact of urbanisation on wildlife. The expansion of urban habitats and the associated human-introduced environmental changes are considered a global threat to the health and persistence of humans and wildlife. The present study experimentally invest

The important role of fire in regulating vegetation community composition and contributions to emissions of greenhouse gases and aerosols make it a critical component of dynamic global vegetation models and Earth system models. Over two decades of development, a wide variety of model structures and mechanisms have been designed and incorporated into global fire models, which have been linked to di

roduction of biomass for bioenergy on marginal land has been promoted to decrease the use of non-renewable energy without competing with food production. Previous estimates of marginal land and abandoned farmland in Sweden available for bioenergy production are based on general statistics and assumptions but lack in-depth analyses of potential alternative land-use values.

Rapporten sammanfattar fjärilsinventeringar utförda 2020 inom Biogeografisk uppföljning som drivs av Naturvårdsverket. I fjällområdet kunde totalt 49 ytor inventeras. Sammanlagt noterades 151 högnordiska blåvingar på 22 inventerade ytor, 53 dvärgpärlemorfjärilar på 25 ytor och minst 1 fjällsilversmygare noterades på 3 inventerade ytor. Svartfläckig blåvinge observerades på 15 av 50 inventerade lok

Amazonian ecosystems range from rainforest to open dryland vegetation, with a following decrease in biomass along the moisture gradient. Biomass can vary greatly at the ecological transition zone between grass dominated savannahs and the forest. It is not well understood if the transition zone could expand under climate change, and thereby reduce ecosystem stability and carbon storage in biomass.

Urban tourism depends on the place specific qualities of destinations. In many cities, climate change poses a threat to these qualities, through increasing risk of excessive heat, draught and flooding. Cities need to adapt to reduce these risks. One way of doing this is to improve their green infrastructure. Urban forests, parks, rivers and wetlands may help reduce the effects of climate change in
