The present thesis explores how the tourist experience is re-articulated through the mediation of smartphones. I adopt the postphenomenological theory of mediation as the overarching ontological position, placing the role of technologies on an ontological level, as mediators of perception and experience. The new tourist that emerges from smartphone mediation is the smartphoned tourist, that is a t
It is of great importance to understand how terrestrial ecosystems will respond to global changes. However, most experimental approaches have focused on single factors. In natural systems, moisture and temperature often change simultaneously, and they can interact and shape microbial responses. Even though soil moisture and temperature are very important factors controlling microbial activity, the
This report is an external evaluation of the scientific basis of the Norwegian assessment system for ecological condition (Fagsystem for økologisk tilstand), commissioned by the Ministry of Climate and Environment (KLD). Two assessment methods are currently used for various terrestrial and marine ecosystems: the Panel-Based Assessment of Ecological Condition (PAEC) and the Index-Based Ecological CThis reportis an external evaluation of the scientific basis of the Norwegian assessment system for ecological condition, commissioned by the Ministry of Climate and Environment.

Bioenergi spelar idag en stor roll i det svenska energisystemet ur klimat- och energisäkerhetssynpunkt men vilken roll kan inhemsk bioenergi komma att spela framöver för att Sverige ska bli ett fossilfritt samhälle med nettonollutsläpp 2050? Syftet med denna rapport är att utifrån olika perspektiv beskriva hur tillförseln av inhemska skogsbaserade biobränslen kan komma att förändras under perioden
Innovation is generally viewed as something inherently good, a source of progress and prosperity in our society. But innovation can also have negative, unintended, and wasteful effects, if policies are misdirected and organizations pursue innovation to look good and convey a message, rather than to actually achieve improvements of technologies, services, and products. This book makes the case that
Humanity injects an almost incomprehensible 42 billion tonnes of carbon dioxide (CO₂) into the atmosphere every year. The majority of this comes from burning fossil fuels, but a substantial portion, about 16%, arises from how we use the land. Most of these land-use emissions are caused by deforestation, particularly in the tropics.In order to slow climate change, the global community needs to redu
The loading of macroelements such as, dissolved organic carbon (DOC), totalnitrogen (N) and total phosphorus (P) from terrestrial soils to aquatic systems isincreasing in the northern hemisphere. This phenomenon has several ecologicaland biogeochemical consequences for inland and coastal water systems, which arelinked to bacterial cycling of DOC, N and P. During growth, bacteria assimilatemacroeleThe loading of terrestrially derived macroelements, such as dissolved organic carbon (DOC), total nitrogen (N), and total phosphorus (P), to inland and estuarine waters is increasing in the northern hemisphere. Thesemacroelements often limit heterotrophic bacterioplankton metabolism (production and respiration), which in turn influence food web structures, exchange of greenhouse gases between the
Terrestrial ecosystem gross primary productivity (GPP) is the largest land-atmosphere carbon flux and the primary mechanism of photosynthetic fixation of atmospheric CO2 into plant biomass. Anomalous rainfall events have been shown to have a great impact on the global carbon cycle. However, less is known about the impact of these events on GPP, especially in Africa, where in situ observations are
Taking a performance perspective of entrepreneurship as the point of departure, the social action of entrepreneurship is examined through an interactionist lens. In particular, it applies the micro-sociology of interactionism of Erving Goffman as expounded in his seminal essays ‘On Face-Work’ and ‘The Nature of Deference and Demeanour’. The paper explores entrepreneurship through a case study of a
The aim of this study was to investigate the psychometric properties of the Swedish version of the Dissociation Questionnaire in a normative adolescent population and also to investigate dissociative symptoms associated with trauma including sexual and physical abuse. A normative sample of 449 adolescents between the ages of 12 and 19 and a clinical group of 74 adolescents with known experiences o
Most state-of-the-art natural gas-fired combined cycle (NGCC) plants are triple-pressure reheat cycles with efficiencies close to 60%. However, with carbon capture and storage, the efficiency will be penalized by almost 10% units. To limit the energy consumption for a carbon capture NGCC plant, exhaust gas recirculation (EGR) is necessary. Utilizing EGR increases the CO2 content in the gas turbine
I Skåne kan klimatförändringarna förbättra förutsättningarna för produktion av grödor och annan biomassa via förlängd växtsäsong och ökad tillväxt. Samtidigt ökar dock risker för skador, sjukdomar och insektsangrepp. En intensifiering av jordbruk för att ta vara på ökad produktionspotential och för att möta ett ökat behov av biomassa riskerar att förvärra problem som redan finns när det gäller fö
Cerium dioxide, or ceria, is a chemically stable oxygen ion conducting material with a capacity to store and release oxygen, and is therefore extensively used in combustion catalysts. The Cu-Ce-O system has been identified as one of the most active catalysts for the combustion of carbon monoxide. To study the catalytic oxidation of CO, we have synthesised model CuOx/CeO2 cata
Objective: This multiple case study investigated support and process in the Individual Placement and Support (IPS) approach from individual client, longitudinal and Person-Environment-Occupation (PEO) model perspectives. Participants: Five IPS-participants, or cases, with severe mental illness (SMI) who worked a minimum of 4 hours a week entered the study. Methods: A multiple data collectio
There has been little development regarding analysis of polonium (Po) in environmental samples since the 1960ies. This is due to the straightforward spontaneous deposition of this element on silver (Ag), nickel (Ni) or copper (Cu) without any radiochemical separation. For many years, no radiochemical yield determinant was used and it was generally supposed that the yield was 100% after two deposit
