    Abstract [en]

    Shielings (Sw. fäbod or säter, No. seter) functioned as a means for expanding agrarian enterprises (mainly the grazing of cattle) from the farmstead or hamlet to areas lying outside those fields that were currently being worked. Shielings were used mainly in regions whose climatic conditions were difficult or who had limited acreage. The classic Scandinavian shieling consisted of a fenced site in outlying lands which included structures for dwelling, stabling cattle, processing milk and meadows for haymaking. The cattle were grazed in the forests surrounding shielings and guarded by female herders

    Empowering marginal lifescapes: The heritage of crofters inbetween the past and the present2017In: International Journal of Heritage Studies (IJHS), ISSN 1352-7258, E-ISSN 1470-3610Article in journal (Refereed)
    Abstract [en]

    There is a rich, but unacknowledged, heritage of rural subalterns, crofters, in Scandinavia. A Swedish-Norwegian interdisciplinary research-network investigated the most prominent category – the remains of crofts. Due to industrialisation, urbanisation and the modern welfare state, the institution of crofting was abolished, and many crofters left for opportunities elsewhere. The welfare state transformed a landscape of living and working people into a one filled with relicts mostly from the nineteenth century. Although numerous and important to local citizens, these sites fall outside the authorised heritage discourse (AHD) in terms of both research and heritage management. This paper takes an environmental justice perspective to challenge the AHD. Three themes are in focus: (1) bringing out the history of a subaltern and marginalised group of people; (2) promoting crofts as heritage of importance to local citizens and demanding complex management due to the various historical narratives and risks; (3) considering the crofting landscapes in relation to the (economisation) framing of heritage in development processes, especially in relation to fair development in present rural communities.

    Abstract [en]

    This paper aims to present a recently started project about the heritage of subaltern people in Sweden. In the paper we focus on the parts of the project that concerns the rural history of the 18th and 19th centuries, especially crofters. The background to the project is the introduction of major changes in the Swedish Historic Environments Act in 2014. A radical novelty is that remains of human activity and buildings executed before AD 1850 now are legally protected sites. With this change a large number of remains, including hitherto un- or underresearched types, are to be included in heritage management, conservation and rescue archaeology. Here we present the background and starting points of the project, in order to show the potential of archaeological studies of landless subalterns in rural areas.

    Experimental hydraulics on fish-friendly trash-racks: an ecological approach2018In: Ecological Engineering: The Journal of Ecotechnology, ISSN 0925-8574, E-ISSN 1872-6992, Vol. 113, p. 11-20Article in journal (Refereed)
    Abstract [en]

    The obstruction of fish migratory routes by hydroelectric facilities is worldwide one of the major threats to freshwater fishes. During downstream migration, fish may be injured or killed on the trash-racks or in the hydropower turbines. Fish-friendly trash-racks that combine both ecological and technical requirements are a solution to mitigate fish mortality at a low operational cost. This study presents results from an experimental investigation of head-losses and the hydrodynamic performance of six angled trash-rack types with 15 mm bar spacing, varying bar-setup (vertical-streamwise, vertical-angled and horizontal bars) and bar profiles (rectangular and drop shape) under steady flow conditions. The trash-racks were positioned at 30 degrees to the wall of the flume and combined with a bypass at their downstream end. The impact of the different trash-rack types on the upstream flow field was characterized using Image based Volumetric 3-component Velocimetry (V3V) and at the bypass-entrance using an Acoustic Doppler Velocimeter (ADV). The results show that trash-racks with vertical-streamwise and horizontal oriented bars with drop-shape profiles have similar head-losses (13% difference), while trash-racks with vertical-angled bars provide 3-8 times larger head-losses compared to the remaining configurations. The velocity measurements showed that the highest flow velocities occurred for configurations with vertical-angled bars (0.67 m s(-1) and 0.81 m s(-1) on average, respectively). Turbulence related parameters (e.g. Reynolds shear stresses and Turbulent kinetic energy) were also investigated to evaluate the performance of the alternative trash-racks from both, engineering and ecological perspectives.

    En skitig historia: - En studie kring varför samhällen slutar använda mänsklig avföring som gödsel vid matodling.2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Phosphorus is an essential nutrient in agriculture, despite this fact we are well on our way to using up the phosphorus we have access to in the ground. This study has therefore focused on a major source of phosphorus that is not taken into consideration in a vast majority of today’s societies: human excrement. Many countries have used human excreta as a resource throughout history, including as a fertilizer when producing food, which ensured that a major part of the phosphorus was returned to the soil. In societies today human excrement is viewed as something unwanted and disgusting. What is it that makes humans hesitant to use this source of phosphorus? Why did societies stop using human excrement as a fertilizer when growing food? The purpose of this study is to examine the underlying causes for why people stop using human excrement as a fertilizer when producing food. A thematic analysis, combined with selected parts of a comparative analysis, has been used to analyze apt publicized material. This analysis has resulted in the study’s result, which has then been pitted against the theoretical framework for this study. The theoretical framework includes: people’s view of their own excreta, dirt and cleanliness, and human excreta as a resource. The result suggests that it primarily is an increased urbanization and a modernization of society that leads people to stop using human excrement as a fertilizer when producing food. Human perception of purity is pitched against the view of human excrement as a resource. The choice of using human excrement or not is governed by the cultural perception of what is clean and what is dirty. When the negative associations connected to human excrement outweigh the positive, then humans distance themselves from it, even though the excrement could still be used as a resource.

    Att systematiskt hantera kunskap vid planering av ny infrastruktur: En fallstudie om skyfallsskador på riksväg 90 i Kramfors kommun2014Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Natural disasters are becoming more common due to climate change and it is important to adapt the society and its infrastructure to withstand events such as extreme rainfall. Precipitation is an important climatic factor affecting the transport and annually generates the cost of millions in damages, over the past 40 years heavy rain has increased and will continue to increase in the future. The extreme rainfall that occurred in Kramfors municipality in September 2013 led to flooding and destroyed several roads, including highway 90, which recently both had been rebuilt and given a new stretch of road. Extreme rainfall had also occurred in the municipality earlier.  

    The aim of the thesis was to examine how the Swedish Transport Administration handles new knowledge gained after natural disasters and how this is used in the planning of new roads. From the aim of the study a case study was used as a method. Information was sought from reports, official documents and government investigations in order to see how the Swedish Transport Administration’s work looks like and to find studies about the incident on highway 90. There were also conducted interviews with informants within the Swedish Transport Administration to find out how the planning and investigation of roads looks like, and to get information about the work of national highway 90.

    Within the Swedish Transport Administration lessons are learned from natural disasters and events in the past, but learning is mainly individual - based and internally. There is no system in the Swedish Transport Administration to manage new information or collect past experiences. New knowledge and new conditions are used in the investigation and planning of roads, but depends on which people work with those. The planning of highway 90 follows the regulations and plans to be followed, but with additional information on past events and climate adaptation in those, the damages caused by the extreme rain on highway 90 could perhaps have been avoided.

    Att anta den nationella miljömålsutmaningen i mindre kommuner: En fallstudie om hur Sveriges mindre kommuner arbetar med miljömålsutmaningen2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sveriges miljömålssystem implementerades 1999 och har sedan dess varit en nationell utmaning till Sveriges kommuner. När systemet antogs i Sveriges riksdag så angavs 2020 som systemets slutår, till vilket den miljömässiga kvaliteten som miljömålen definierade skulle ha uppnåtts. I dagsläget har Naturvårdsverket dock bedömt att enbart två av de sexton nationella miljömålen kommer att nås, vilket påvisar hur Sveriges samhällsutveckling inte är i linje med den som miljömålssystemet förespråkar.

    I undersökningar som gjorts har det påvisats att det främst är mindre kommuner som upplever att systemet är en stor utmaning. I denna fallstudie studeras således på vilket sätt som dessa kommuner upplever en problematik med miljömålen och vad som händer då beslut ska tas som främjar en miljömässig hållbarhet. I fallstudien har dokumentanalyser och intervjuer genomförts i en representativ kommun i Mellansverige.

    Fallstudien påvisar hur ekonomi ofta får vara den bestämmande faktorn vid kommunala beslut och projekt, vilket bidrog till att miljömålen fick en lägre prioritet. Förutom att studien visade att ideologiska faktorer utgjorde motsättningar till både miljömålsarbetet och det generella miljöarbetet, så visade studien även på hur det fanns organisatoriska brister.

    Linguistic Challenges in Science Education: A Classroom Study of Teachers’ and Students’ use of Central Concepts in Genetics2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis examines linguistic aspects of genetics education and is based on the view that language is an essential dimension of teaching and learning. Its objective is to clarify how teachers and students use genetics concepts in real teaching situations. By studying the spoken language used in lessons, I explore how teachers present the subject and the opportunities students have to learn to use the specific language of genetics. These explorations help explain why genetics is such a challenging topic to teach and learn, as shown by previous studies. My study is based on observations and recordings of genetics lessons for grade nine students, i.e. students in the final year of compulsory education in the Swedish school system. Four classes were followed as they progressed through the genetics unit. The corpus was analyzed with different linguistic methods to reveal patterns in the way teachers use and interrelate core concepts such as gene, DNA and chromosome, how they connect the concepts of gene and trait, and how students are involved in dialogue about core genetics concepts. Teachers were found to use genetics concepts with varying meanings and interrelated words in many different ways, resulting in an ambiguous and inconsistent communication of the genetics content in the classroom. The students used the genetics concepts much less frequently than the teachers, and mainly used them in short sentences. This suggests that current teaching practices do not give students enough opportunities to develop the language of genetics. My results demonstrate several aspects of classroom talk that could contribute to the learning difficulties associated with genetics. It will be important to take these aspects into account when seeking to improve the teaching of this subject.

    This study investigates Swedish biology teachers’ inclusion of proteins when teaching genetics in grade nine (students 15-16 years old). For some years there has been a call for the attention of proteins in teaching genetics as a mean of linking the concepts gene and trait. Students are known to have problems with this relation because the concepts belong to different organizational levels. However, we know little about how the topic is taught in the classroom and therefore this case study focus on how four teachers talk about proteins while teaching genetics, and if they use protein as a link between micro and macro level. The four teachers were observed and audio recorded during entire genetics teaching sequences, 45 lessons in total. The teachers’ verbal communication was then analyzed using thematic pattern analysis, which is based in systemic functional linguistics (SFL). The linguistic analysis of teachers’ talk in action revealed great variations in both the extent to which they used proteins in explanations of genetics and the ways they included proteins in the linkage between genes and traits. Two of the teachers used protein as a link between gene and trait, while two did not. Three of the four teachers included instruction about protein synthesis. The common message for all teachers was that proteins are built, but none of the teachers talked about genes as exclusively encoding proteins. Our results show some possible examples of how proteins could be used in teaching genetics at this age level. However, they also suggest that students’ common lack of understanding of proteins as an intermediate link between gene and trait could be explained by shortcomings in the way the subject is taught.

    Linguistic challenges in Mendelian genetics: teachers' talk in action2013In: Science Education, ISSN 0036-8326, E-ISSN 1098-237X, Vol. 97, no 5, p. 695-722Article in journal (Refereed)
    Abstract [en]

    This study investigates Swedish teachers’ use of language when teaching genetics in grade nine (students 15-16 years old). Mendelian genetics comprises a substantial part of the genetics taught in many classrooms, including the central relation between the gene and trait concepts. This relation has been identified as a significant problem in teaching and learning genetics, but few satisfactory explanations of its difficulty have been suggested. Thus, the primary objective of the study is to reveal how teachers explain and relate gene and trait (i.e. gene function) while teaching Mendelian genetics, in order to shed light on this problem. Four teachers were observed and recorded through a whole sequence of genetic teaching. The empirical data consist of records of their communications during 45 lessons. Their verbal communications were analyzed using a linguistic framework called thematic pattern analysis. The linguistic analysis of teachers’ talk in action revealed that nuances in their spoken language conveyed four major categories of meanings regarding the gene-to-trait relationship: genes control traits, are identified by traits, have traits or are traits.  The results also reveal a common use of an old word, anlag (from the German word Anlage), in the teachers’ references to the meaning of both gene and trait. This study thus highlights several linguistic challenges in the teaching of Mendelian genetics that might affect students’ learning. Moreover, the study exemplifies how a linguistics methodology can be used to investigate science teaching, an approach heavily called for, but rarely used in published empirical studies.

    Ingen kan inte göra allt, men alla kan göra något?: En komparativ studie om hur individer resonerar kring miljöansvar i vardagen2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study is based on discussions with three focus groups on the issue of individuals' views on environmental responsibility in everyday life. Responsibility is the red thread that emerged from the empirical material from the focus groups and the theoretical framework. The discussions have been focused on whether the problems from household related environmental issues are caused by individual or structural reasons and whether they should be resolved through changes in individuals' behavior or helping structures. Car usage has been a particular focus, since from all household activities that is the one causing the greatest environmental impact (SCB 2015b).

    Objectively speaking, most participants argued that environmental problems are or should be easy to solve and that the solutions should involve influencing individuals' values ​​and norms, thus referring to internal factors. Based on the individual's own situation, however, most participants indicated mainly external factors as obstacles from living out environmental responsibility in the way that they felt they should. Tendencies of various psychological and sociological defense mechanisms could be distinguished, which is an expected impact of the cognitive dissonance that many apparently are experiencing regarding environmental responsibility. Working for enabling structures is an important conclusion from this study. Regarding the car's role it is likely that it is about finding more ways of helping individuals to change their travel mode since the environmental impact of car usage is something that most people are aware of, but feel unable to change. Solutions must therefore involve external factors.

    Ryktet går: En studie om riskkommunikation i sociala medier bland kommuners kommunikatörer i Jönköpings och Värmlands län2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In this thesis, we have studied municipal communicators' view on social media as risk communication tool and how they use social media as a communication channel to make society better in dealing with risks and crises. There has been an explosive development of social media in the last ten years, and this has meant that previous research on social media as a risk communication tool is outdated and new opportunities and dilemmas have been identified. Eight qualitative interviews with communicators from Jönköping and Värmland County municipalities were conducted and the interviews were analyzed based on thematic analysis. A total of seven municipalities participated, one of who did not use social media as a risk communication channel during the time the interviews were held. The results show that the possibilities of social media outweigh the disadvantages, and that the communicators perceive fake news and misinformation as the biggest challenge. Some previously identified paradoxical relationships with risk communication persist, others are seen as less problematic when five additional paradoxical conditions have been identified in connection with the increased use of social media as a risk communication tool.

    Metoder för att etablera fri station: En jämförelsestudie av GNSS-etableringar och traditionell etablering2017Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [en]

    The purpose of this degree project is to compare the quality obtained from different types of free station establishment. Three different methods have been compared. The methods are establishing towards control points (traditional method), establishing towards GNSSdetermined points with a fast method and establishing towards GNSS-determined points with a slow method.

    The fast method is to measure a point with five (5) positions with GNSS while the total station measures the point as backsights simultaneously. Using this method each point needs to be visited only once. The slow method is to first measure all points to be used as backsights with 20 positions with GNSS, then return to each point and measure them with the total station. Each point must then be visited twice.

    Three control points in the city of Arvika were used as backsights. It was also those points that were measured with GNSS to compare the quality of GNSS measurements relative to their "true" coordinates extracted from the point description. Different number of backsights were used to investigate how the quality changed as more backsights were added.

    Free station establishment was performed with each method using three, five and seven backward objects. Three measuring rounds were made to compare the measurements in each round with each other.

    Conclusions drawn are that, when updating the primary chart, it is sufficient to use the fast GNSS method along with three backsights to achieve satisfactory quality, but in construction measuring where the quality needs to be very high the slow method with five backsights should be used instead.

    The work also describes the theory behind GNSS technology and free station.

    GNSS-mätning vid olika tidpunkter: En studie om osäkerhet2017Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study is to investigate whether different times during a day affect GNSSbased measurements. To investigate this, measurements were made on two known points at several occasions. The measurements compared are made in the morning, afternoon and evening. The points used are located in Östersund and in Hallen. The equipment that was used were a Nomad handheld computer and a TopCon Hiper II GNSS receiver with tripod and footer. The measurements were performed with NRTK in the coordinate system SWEREF99 14 15. The data was analyzed in SBG GEO and then compared in Microsoft Excel. The result was an average radial difference of 3 mm in plane. At three out of four times, the accuracy was better in the morning than in the afternoon/evening. The maximum difference between measurements was 8 mm.

    Marine ecosystem connectivity mediated by migrant-resident interactions and the concomitant cross-system flux of lipids2016In: Ecology and Evolution, ISSN 2045-7758, E-ISSN 2045-7758, Vol. 6, no 12, p. 4076-4087Article in journal (Refereed)
    Abstract [en]

    Accumulating research argues that migrants influence the functioning and productivity of local habitats and ecosystems along migration routes and potentially drive cross-system energy fluxes of considerable magnitude, yet empirical documentation of local ecological effects and descriptions of the underlying mechanisms are surprisingly rare. In this study, we discovered migrant-resident interactions and substantial cross-system lipid transportation in the transition zone between the Baltic Sea and the North Sea where a resident cod population (predators) was found to interact with a herring population (prey) on a seasonal basis. We traced the lipids, using fatty acid trophic markers (FATM), from the herring feeding grounds in the North Sea to the cod livers in the Western Baltic Sea. Time series analysis of population dynamics indicated that population-level production of cod is positively affected by the herring subsidies. However, the underlying mechanisms were more complicated than anticipated. During the herring season, large cod received most of its dietary lipids from the herring, whereas smaller cod were prevented from accessing the lipid pool due to a mismatch in predator-prey size ratio. Furthermore, while the herring were extremely rich in bulk energy, they were surprisingly poor in a specific functional fatty acid. Hence, our study was the first to illustrate how the magnitude cross-system fluxes of subsidies in migrant-resident systems are potentially constrained by the size structure of the resident predator population and the nutritional quality of the migrants.

    Effect of incubation temperature on Atlantic salmon metabolism as indicated by ventilation rate2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The global mean temperature is predicted to increase by up to 5 °C during this century. For fish, being ectotherms, temperature is one of the most important environmental factors, influencing them in a number of different ways, including effects on physiological traits, timing of life history events and behavior. Atlantic salmon has been shown to grow faster after being incubated at warmer temperatures. One possible explanation for this could be that the increased incubation temperature causes decreased metabolic rates. The aim of this project was to examine whether this is true. Atlantic salmon eggs were incubated in three different temperature regimes: natural temperature conditions, heated water and a mixed temperature treatment, where eggs were incubated in increased temperature until the beginning of January and after that subjected to natural temperature conditions. Ventilation rate, a proxy for metabolism, was measured for fish from each treatment group, as well as fish length and weight. The results revealed significantly lower ventilation rates of the fish from the heated temperature treatment, but not of the fish from the mixed temperature treatment. This suggests that an increased incubation temperature causes lowered rates of metabolism in Atlantic salmon, and that the change occurs later than early January. Because of differences in size and life stage between fish from the different groups however, the results are uncertain and call for further investigations. A lowered metabolic rate will affect the fish’s behavior. A further development might therefore be to study fish survival in the wild in relation to a fish’s metabolic rate.

    Skillnader i födoval mellan brunbjörnshonor (Ursus arctos) med och utan årsungar2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    According to foraging theory, animals seek and consume food in ways that maximize their ability to reproduce and have their genes represented in future generations. In order to achieve this, individuals must sometimes adapt their behaviors. Females of the brown bear (Ursus arctos) with cubs of the year must share the food they find with their cubs. To protect the cubs from being killed by males in the mating period, females with young have smaller home ranges than other adult females and move less on a daily basis than other females. In view of these differences my hypothesis is that females with yearlings consume different food items than other females. A fecal collection from GPS-marked brown bears was made in 2015 in the northern Dalarna county and northwestern county of Gävleborg in Sweden from 25 May to 11 October. Prior to the data analysis, the season was divided into two periods, 25 May to 15 July and 16 July to 11 October, based on differences in food availability and season (mating vs non-mating season). A frequency analysis detected no significant differences in food items consumed for either period. However, an exploratory data analysis of percent volume of different food items suggests that there may be differences in the amount of certain foods during the mating period. These differences were found for the food categories, bone, moose hair and other plant material. Although the study suffers from a small sample size with only four females with cubs of the year in each of the two periods, this study is relatively novel with a resolution at the individual level. Previous food item analyzes of the brown bear in Scandinavia have been done with fecal samples as the smallest unit.

    Abstract [en]

    The eu-oceanic therophytic woodland herb Ceratocapnos claviculata has been expanding north- and eastwards into north temperate and subcontinental regions during the past decades. The rapid range expansion of the species may be an example of a species which is strongly profiting from global change. Against this background, in the present paper we review the taxonomy, morphology, distribution, habitat requirements, life cycle and biology of the species. (C) 2011 Elsevier GmbH.

    From doing to learning: Inquiry- and context-based science education in primary school2016Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The aim of this thesis is to develop an understanding of primary school teachers’ knowledge of Inquiry- and Context-Based Science Education (IC-BaSE) from different perspectives: what it is, how to use it and why these strategies are used. There are at least two reasons for performing research in this field. First, there is a need for professional development in teaching science among primary school teachers. Second, IC-BaSE has been suggested to provide useful instructional strategies for stimulating students’ interests in learning science. The thesis contains four papers with the overall research question: How do primary school teachers reflect on Inquiry- and Context-based Science Education as a framework for teaching and learning in the primary school classroom? Both quantitative and qualitative research methods have been used. The main participants in the studies were twelve primary school teachers working with 10-12 year old students. The results are discussed with reference to theories mainly based on pragmatism, but also from a sociocultural perspective. Primary school teachers found IC-BaSE to provide useful instructional strategies in the primary school classroom, as it engaged their students and developed their skills in planning inquiries. The teachers developed their knowledge about IC-BaSE, what it is and how to use it.  Furthermore, the primary purpose of using IC-BaSE seemed to be that students should have fun. Students also responded positive to the use of IC-BaSE. However when teachers were informed about their students’ responses to IC-BaSE, they became more aware of the importance of informing the students about the purposes of the activities. The findings presented show that teachers need to move forward, not only be “doing”, but also knowing why they are doing the activities and how to do them. Students’ experiences can contribute to this awareness among teachers and develop the teaching practice.

    Students' responses to visits at some researchers' night events2017In: NFSUN 2017 Synopsis Book, 2017, p. 26-29Conference paper (Refereed)
    Abstract [en]

    Several activities around the world aim to stimulate students’ interest in science, technology, engineering and mathematics. The European Researchers' Nights are one example. In this study it was investigated how seven students in the age 15-19 years responded to a visit at Researchers' Nights events. The students were interviewed and answers were analysed based on content. The results showed that the students were all positive to the visit and in most cases it was better than they had expected. The results were organised into the main themes: expectations versus experiences, interest in research context and relevance of research. Most of the students were positive about being a scientist and could even imagine a future science career. The contexts presented at the events were catching the interest of the students and were relating to the daily life of the students, or found to be of relevance for society. The study is a pilot and will be followed by a future study with more students included.
