Konferensbidrag (refereegranskat)abstract
- Children and young adults are important target groups in order to decrease the climate change effects and increase an energy-efficient end use. With increased knowledge and awareness these target groups could play a constructive role in the current and future transition of the energy system. The correlation between knowledge, awareness and behavioral change is central for improved energy efficiency in the society. Children and young adults and their interest in the natural and technical science are central to ensure the long-term capability needed to transform the energy system.To support this development the Swedish Energy Agency started with young adults as a target group in research and development projects in 2008. Since then approximately 5 million EUR has been allocated for projects aiming to increase knowledge in these areas among young adults by developing practical methods and tools, educational material or in-service training for teachers. Around thirty projects have been supported and three of them, KNUT school development project, KNUT evaluation research project and The Energy Fall, will be discussed in this paper. The KNUT school development project is a national school project aiming at increasing students’ knowledge and interest in energy and energy efficiency. KNUT also stimulates learning and career choices related to energy, climate and resources and therefor strengthen Sweden's capacities and competitiveness future in these areas. To ensure the scientific base a research group from Linköping University (KNUT evaluation research project) has followed the project’s activities. Best practices of methods and tools have been tested and disseminated within the project at both regional and national level. The KNUT evaluation research project has identified and analyzed five success factors regarding energy, climate change and energy efficiency of importance for education: The relationships between the national, regional and local levelThe function of education vary in time due to the development of societyGet to know the education content inside and outside of schoolSuccessful meetings between different actorsThe educational systems capacity to educate all and at the same time recruit some for specializationThis paper will present an overview of the Swedish Energy Agency’s work on research and development projects aiming to increase young adults’ knowledge of energy and energy efficiency and the KNUT evaluation research project results, analysis and success factors.

Barns teckningar som utgångspunkt i det naturvetenskapliga samtalet
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Barns föreställningar utgör en viktig del i deras begreppsbildning inom naturvetenskap vilket betonas inom konstruktivismen. I denna avhandling utgör en socialkonstruktivistisk syn på lärande det teoretiska ramverket. Det övergripande syftet med avhandlingen är att i samtal med barn i åldrarna 4–13 år och med utgångspunkt i deras teckningar, utveckla kunskap om de föreställningar de ger uttryck för inom fyra naturvetenskapliga områden: värme, blandning, människokroppen och vad som är levande/inte levande. Två forskningsfrågor behandlas i avhandlingen: Vilka föreställningar ger barn uttryck för i teckningar och i samtal om naturvetenskapliga fenomen? Vilka metodologiska förutsättningar och utmaningar finns det när det gäller att använda teckningar som utgångspunkt och som meningsskapande redskap för att fånga barns föreställningar? En multimodal metod bestående av teckningar, samtal och barnens aktivitet användes vid datainsamlingen, vilket är i linje med ett socialsemiotiskt perspektiv.Avhandlingen består av fyra studier. Resultatet i de två första studierna visar att barns föreställningar om blandningar var något mer utvecklade än vad som visats i tidigare studier, medan deras föreställningar gällande värme överensstämde med vad som tidigare rapporterats.Den tredje studien visar att barnen känner till fler organ i människokroppen och visar, till skillnad från vad som framkommit i tidigare forskning, förmåga att rita kopplingar mellan organen. I den fjärde studien talar en majoritet av barnen om död som en motsats till liv och några ritade att det som inte lever tidigare har levt. Barn som är medvetna om mikroskopiska objekt klassificerar dem som levande. Förklaringarna visar på en inkonsekvens i barnens resonemang om växter lever eller inte.Metodologiskt framkom att barns föreställningar med fördel fångas genom deras egna teckningar tillsammans med deras förklaringar av dessa. Teckningarna fungerar även som hjälpmedel för att föra fram och delge olika resonemang. I avhandlingen diskuteras barns lösningar på rittekninska problem som de mötte vid sidan av den naturvetenskapliga uppgiften. I studien om människokroppen handlar dessa problem om svårigheten i att överföra den tredimensionella människokroppen till två dimensioner. En annan svårighet var att kroppens organ, skelett, muskler och vävnader ligger ovanpå varandra. Där använde barnen strategin att rita röntgenbilder för att visa det som ligger dolt. Barn i olika åldrar löste ofta dessa rittekniska problem på ett mycket kreativt sätt i kombination med deras muntliga/skriftliga kommentarer. Förutom teckningarnas betydelse diskuteras skillnaden mellan kontextualiserade och dekontextualiserade uppgifter. De olika områdena som studerats i avhandlingens artiklar befinner sig på olika abstraktionsnivåer vilket påverkar barnens föreställningar och hur detta uttrycks in bilder. Naturvetenskap innefattar olika dimensioner där det handlar om att både lära sig strukturell och processuell kunskap. Den multimodala metoden gav barnen hjälp med att samla, strukturera och uttrycka sina tankar

Tidskriftsartikel (refereegranskat)abstract
- This paper presents a study of children’s ideas of the body’s internal structure. Children between four and 13 years (N = 170) individually produced drawings. During each drawing session the children explained their drawings to a facilitator and added written labels either by them- selves or, if they were too young to write, with the facilitator’s help. The results provide an updated comprehensive picture of children in differ- ent age groups and their views on the internal structure of the body. The type and numbers of organs drawn are similar to those documented in previous studies. However, in comparison to recent studies, the children drew more organs, the brain was indicated almost as often as the heart, and the Valentine heart was frequently used as a symbol. In contrast with previous research, children drew connections between organs. This result calls for caution regarding conclusions made from decontextua- lized questions. The importance of providing children with the opportu- nity to clarify their drawings is emphasised since it otherwise becomes a question of the researcher’s interpretation. The connections they draw, and explanations they give to their drawings, have interesting implica- tions for understanding children’s ideas, and hence both for teaching and learning and for science education research.

Measuring greenhouse gas fluxes : what methods do we have versus what methods do we need?
- 2022
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Appropriate methods to measure greenhouse gas (GHG) fluxes are critical for our ability to detect fluxes, understand regulation, make adequate priorities for climate change mitigation efforts, and verify that these efforts are effective. Ideally, we need reliable, accessible, and affordable measurements at relevant scales. We surveyed present GHG flux measurement methods, identified from an analysis of >11000 scientific publications and a questionnaire to sector professionals and analysed method pros and cons versus needs for novel methodology. While existing methods are well-suited for addressing certain questions, this presentation presents fundamental limitations relative to GHG flux measurement needs for verifiable and transparent action to mitigate many types of emissions. Cost and non-academic accessibility are key aspects, along with fundamental measurement performance. These method limitations contribute to the difficulties in verifying GHG mitigation efforts for transparency and accountability under the Paris agreement. Resolving this mismatch between method capacity and societal needs is urgently needed for effective climate mitigation. This type of methodological mismatch is common but seems to get high priority in other knowledge domains. The obvious need to prioritize development of accurate diagnosis methods for effective treatments in healthcare is one example. This presentation provides guidance regarding the need to prioritize the development of novel GHG flux measurement methods.

Tidskriftsartikel (refereegranskat)abstract
- Recently, there have been growing concerns about pharmaceuticals including antibiotics as environmental contaminants. Antibiotics of concentrations commonly encountered in wastewater have been suggested to affect bacterial population dynamics and to promote dissemination of antibiotic resistance. Conventional wastewater treatment processes do not always adequately remove pharmaceuticals causing environmental dissemination of low levels of these compounds. Using constructed wetlands as an additional treatment step after sewage treatment plants have been proposed as a cheap alternative to increase reduction of wastewater contaminants, however this means that the natural microbial community of the wetlands becomes exposed to elevated levels of antibiotics. In this study, experimental surface-flow wetlands in Sweden were continuously exposed to antibiotics of concentrations commonly encountered in wastewater. The aim was to assess the antibiotic removal efficiency of constructed wetlands and to evaluate the impact of low levels of antibiotics on bacterial diversity, resistance development and expression in the wetland bacterial community. Antibiotic concentrations were measured using liquid chromatography-mass spectrometry and the effect on the bacterial diversity was assessed with 16S rRNA-based denaturing gradient gel electrophoresis. Real-time PCR was used to detect and quantify antibiotic resistance genes and integrons in the wetlands, during and after the exposure period. The results indicated that the antibiotic removal efficiency of constructed wetlands was comparable to conventional wastewater treatment schemes. Furthermore, short-term treatment of the constructed wetlands with environmentally relevant concentrations (i.e. 100-2000 ng x 1(-1)) of antibiotics did not significantly affect resistance gene concentrations, suggesting that surface-flow constructed wetlands are well-suited for wastewater treatment purposes.

- We used three woodpecker species as umbrella species for old deciduous forests, andanalysed their preferences in an area with old pollarded oaks in the Taurus Mountains,Turkey. Using plot inventories, we physically characterised trees utilised fornesting and foraging amongst woodpeckers in general and the Middle SpottedWoodpecker (Leiopicus medius) in particular. Trees more frequently visited by foragingwoodpeckers differed from randomly chosen trees by being taller, having alarger circumference, greater bark furrow depth and shorter distance to neighbouringtrees. Nesting trees were taller, had a higher proportion of dead wood but a lower surfacearea of natural cavities. Our results suggest that the woodpeckers in the study arearely upon woodlands containing mature trees, thus have the potential to functionas suitable umbrella species’ to highlight the conservation value of oak forest habitatsin southern Turkey.

A strategic approach to sustainable transport system development - Part 2 : the case of a vision for electric vehicle systems in Southeast Sweden
- 2017

Tidskriftsartikel (refereegranskat)abstract
- Electric vehicles seem to offer a great potential for sustainable transport development. The Swedish pioneer project GreenCharge Southeast is designed as a cooperative action research approach that aims to explore a roadmap for a fossil-free transport system by 2030 with a focus on electric vehicles. In the first paper of this tandem publication, the authors propose a new generic process model embedding the Framework of Strategic Sustainable Development. The purpose of applying it in an action-research mode as described in this paper was twofold: (i) to develop a vision for sustainable regional transport and a coarse roadmap towards that vision, and, while doing so, (ii) get additional empirical experiences to inform the development of the new generic process model. Experts from many sectors and organizations involved in the GreenCharge project provided vital information and reviewed all planning perspectives presented in Paper 1 in two sequential multi-stakeholder seminars. The results include a sustainable vision for electric vehicle systems in southeast Sweden within a sustainable regional transport system within a sustainable global society, as well as an initial development plan towards such a vision for the transport sector. The vision is framed by the universal sustainability principles, and the development plan is informed by the strategic guidelines, of the above-mentioned framework. Among other things, the vision and plan imply a shift to renewable energy and a more optimized use of areas and thus a new type of spatial planning. For example, the vision and plan implies a lower built-in demand for transport, more integrated traffic modes, and more multi-functional use of areas for energy and transport infrastructures, for example. Some inherent benefits of electric vehicles are highlighted in the vision and plan, including near-zero local emissions and flexibility as regards primary energy sources. The vision and plan also imply improved governance for more effective cross-sector collaboration to ensure coor- dinated development within the transport sector and between the transportation sector and other relevant sectors. Meanwhile, the new generic process model was refined and is ready to be applied and further tested in the GreenCharge project and in other projects within the transport sector as well as other sectors. The study confirmed that the new generic process model suggested in support of sus- tainable transport system and community development is helpful for giving diverse stakeholders, with various specialties and perspectives, a way of working that is goal-oriented and builds on effective, iterative learning loops and co-creation.

Forskningsöversikt (refereegranskat)abstract
- Caspases are key effectors of the apoptotic process. Some of them play important roles in the immune system, being involved in the proteolytic maturation of the key cytokines, including interleukin 1beta (IL-1beta) and IL-18. The latter directs the production of interferon gamma (IFN-gamma). Among pathogens, particularly viruses express various modulators of caspases that inhibit their activity by direct binding. By evading the apoptotic process, viruses can better control their production in the infected cell and avoid the attack of the immune system. Targeting the maturation of the key cytokines involved in the initiation of (antiviral) immune response helps to avoid recognition and eradication by the immune system. The three main classes of caspase inhibitors frequently found among viruses include serine proteinase inhibitors (serpins: CrmA/SPI-2), viral IAPs (vIAPs) and p35. Their molecular mechanisms of action, structures and overall influence on cellular physiology are discussed in the review below.

Tidskriftsartikel (refereegranskat)abstract
- Encouraging students to enter and persist in science, technology, engineering and mathematics (STEM) programs in higher education has been the focus of STEM education worldwide. To promote social equality particular attention has been given to including student groups such as women, ethnic minorities, and students with low economic status that have long been underrepresented in STEM education. The aim of this research was to examine gender differences in students’ entrance into and persistence in STEM programs in Swedish higher education through the lens of social cognitive career theory (SCCT). Through a quantitative secondary analysis of Interest and Recruitment in Science (IRIS) project data collected in Sweden, a total of 2372 responses were validated and analyzed, including 1530 males (65%) and 842 females (35%). The main findings showed that female students valued previous learning experiences in formal education contexts and social influences more than males, with a significant difference of (p<0.05). Male students valued informal learning experiences more and presented selfefficacy and choice goals to a higher degree, with a significant difference of (p<0.05). No significant gender differences were found with regard to appreciation of current study life. The discussions and implications of the findings and previous research are presented.
