    Riskhantering i kommuner och landsting: ISO 31000, riskbegreppet och organisationsövergripande riskhantering2014Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In 2009 the first ISO-standard focused exclusively on risk management was adopted, ISO 31000:2009. It is supposed to be possible to use it in any societal sector. There is currently little information on how widely the standard has been used, regarding both public and private sector. The study at hand aims to collect information on how it is used in Swedish municipalities and county councils (i.e. local and regional level).  Furthermore, it aims to study how these actors’ risk management relates to some certain aspects of the standard. These are how risk is defined and enterprise risk management.

    A survey has been conducted. All county councils and 48 municipalities were contacted. Sampling regarding municipalities was made by using a categorization made by the Swedish Association of Local Authorities and Regions combined with random choices.

    The results of the study reveal that the use of ISO 31000 is very limited. It is used by two municipalities and not one of the county councils. Some of the latter are however considering using it.  It seems to be the ambition of both municipalities and county councils to apply enterprise risk management in a way that is principally in line with ISO 31000.  

    Furthermore, the results show that municipalities and county councils define risk in different ways. The majority of these organizations say that they use a defined definition of risk in the whole organization. Approximately half of the municipalities use the definition of risk being used by the Swedish Civil Contingencies Agency, i.e. risk is the product of probability * consequence. Amongst county councils only a quarter use this definition. To a larger extent they use definitions that take into account the objectives of their organizations.

    It is hard to judge which consequences this might have. It might be good to know though, e.g. when future governmental controls are being developed.

    The results also show that there are differences between municipalities and county councils when it comes to enterprise risk management, where the latter use it more extensively. There is a gap however between how much enterprise risk management is used and how much municipalities and county councils would like to use it.

    Catch and effort from a recreational trolling fishery in a large lake2016Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Over recent decades recreational fisheries have grown substantially throughout the world. Despite this increase, catches from recreational fisheries have often been ignored in fisheries management, although this is now being remedied. Monitoring recreational fisheries can be expensive, and the primary means used for monitoring is angler (creel) surveys, typically funded from sales of fishing licences. The studies presented in this thesis examine different approaches to monitoring recreational trolling fisheries’ catch and effort, where fishing licenses are not required and there are no reporting requirements. I present results from a complemented roving/mail-in survey undertaken during 2013-2014 to estimate recreational effort and catch of Atlantic salmon (Salmo salar) and brown trout (S. trutta) in the largest lake in the European Union, Lake Vänern, Sweden. I also evaluate different angler catch reporting methods (mail-in, tournament reports and face-to-face interviews) and compare catch rates within and among spring and fall fishing periods. In addition, mail-in survey data are examined for recall bias.

     

    I estimate that 28.7 tonnes of salmon and trout combined were harvested by the recreational trolling fishery in 2014, more than the commercial and subsistence fisheries combined. Seasonal differences in both recreational effort and catch were observed. Effort, in boat hours, was significantly higher in spring than in fall. Catch rates of trout were higher in fall than in spring, but there were no seasonal differences in catches of salmon. Harvest per boat day did not differ significantly among catch reporting methods, indicating that all three methods could be useful for managers interested in harvest rates. In contrast, total and released catch per boat day differed among reporting methods, with tournament anglers catching more fish in total. Finally, there was little evidence for recall bias in mail-in surveys, indicating that mail-in surveys are useful for collecting unbiased catch data. My study is the most comprehensive angler survey to date for Lake Vänern, and my results should be of immediate use to local fisheries managers and should also be of interest to researchers and managers interested in estimating catch and effort for fisheries at large spatial scales.

    Öppna JavaScript-bibliotek för webbkartor i kommunal tjänst: En jämförelse mellan OpenLayers 3 och Leaflet2015Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The use of web-based mapping applications is constantly increasing. In particular, an increase can be observed in the mobile use of such applications. Karlstad municipality is experiencing an increased number of mobile users of its web map. For that reason, the municipality aims to improve their web map in order to provide a more mobile-friendly service. The municipality intends to replace the technology of their existing web map with a more modern alternative and is currently looking at two different JavaScript-based open source APIs for web-based mapping applications – OpenLayers 3 and Leaflet.In this thesis, OpenLayers 3 and Leaflet are compared in terms of compatibility, functionality and performance. Compatibility and functionality are examined primarily through analysis of available documentation. Assessments are made based on requirements set forth by Karlstad municipality, regarding compatibility with existing server architecture and functionality equivalent to the municipality’s current web mapping service.Performance is assessed for WMS and WFS functions, and functions for file based vector data rendering. In addition, differences in performance with various web browsers are evaluated. The performance tests are carried out in environments set up as basic mapping applications. Given functions are tested with simple script methods for timing, together with Firebug, a Firefox web browser plugin.Test results show that both OpenLayers 3 and Leaflet meet all requirements regarding compatibility, even though Leaflet lacks support for certain formats. OpenLayers 3 shows, furthermore, a broader native support for different functions. Leaflet is more limited, natively, but can be extended through various plugins to achieve the same level of functionality as OpenLayers 3.Performance tests consistently show that OpenLayers 3 is the faster API. The results are particularly clear concerning vector data handling, where Leaflet is significantly slower. Despite distinct and measurable differences in performance, the perceived differences are not always as obvious. For this reason, practical user-focused tests are recommended for future studies of the subject.In conclusion, OpenLayers 3 is the recommended API for use in applications of larger scale and with richer functionality, while Leaflet is proposed as a more flexible alternative, suitable for simpler applications.

    Concept Study of a New Method for Drying Dishware in a Heat Pump DishwaterIn: Energy Efficiency, ISSN 1570-646X, E-ISSN 1570-6478Article in journal (Refereed)
    Abstract [en]

    In a heat pump dishwasher, the whole dishwasher with the cabinet, dishware and process water is the heat sink, while a water tank, whose contents will freeze, is the heat source. The aim of the experimental concept study presented here was to evaluate a new drying method for a heat pump dishwasher. In this method, the drying of the dishware occurs as a fan circulates humid air in a closed system in which the water on the dishware evaporates inside the warm dishwasher cabinet and then condenses on a cold surface of the frozen water tank. The evaluation of drying performance was based on the European standard EN50242, which considers visible water drops left on the dishware after a completed dishwashing cycle. The results showed that this new closed drying method was more energy efficient compared to an existing open drying method, and that the drying start temperature and the drying time had a significant effect on the drying performance. Its lower electricity consumption and the fact that it does not vent humid air into the kitchen gives this heat pump dishwasher a competitive advantage over dishwashers using an open drying method.

    Trädsäkring av järnvägen som ett verktyg i Sveriges klimatanpassning: En kvalitativ undersökning av trädsäkring som anpassningsåtgärd2014Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The Swedish Commission on Climate and Vulnerability indicate that climate change may result in an increased average wind speed and the risk of extreme storms may increase in intensity and number. Functions important to society such as road and rail networks must therefore adapt to a changing climate.

    In 2005, Sweden was hit by the storm Gudrun. During this storm fell equivalent to 90 percent of the annual felling of timber and infrastructure was severely affected. Two years later the storm Per occurred, the storm showed once again that the railroad was still very vulnerable and that many of the problems of withstanding severe storms persisted. These two events, particularly Hurricane Gudrun laid the foundation for the Swedish Transport administration to adapt the railways by the felling of trees close to the railways.

    The theoretical premises of the essay is comprised of sustainable development and climate adaptation from a risk perspective.

    This study is conducted based on a qualitative survey with an inductive approach. Data collection methods consisted primarily of interviews whose material then was analyzed through a content analysis.

    The overall aim is to shed light on if Tree removal program is an effective climate adaptation measure, and study the social, economic and ecological consequences of tree management has on the Swedish society.

    The survey results show that both direct and indirect costs which arise from fallen trees may be reduced by the Tree removal program. Tree removal program is a safety measure which may impact both the economy and the environment. The Tree removal program make for example that less priority forest areas become managed in a better way and then get more developed. At the same time the plants that are in need of shadow may be negatively affected by increased sunlight. Based on the changing conditions of the animal and plant life that is created by the security measure it is the common perception among survey respondents that trees management could lead to an increased occurrence of wild animal collisions. The measure also affects the work environment which forest workers are exposed to during harvesting work. In the ongoing Tree removal program it is important that the ruling safety regulations are complied with. The survey results show that there is an increased risk of heat distortion which is both unexpected and an undesirable consequence. Interviews indicate that the tree management could lead to a reduced occurrence of events related to suicide on the railway, this is an unexpected but positive consequence.

    Student 'sustainability consciousness' and decision making on sustainability dilemmas: Investigating effects of implementing education for sustainable development in Swedish upper secondary schools2014Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    The central role of education for sustainable development (SD) has been emphasized since the 1990s. SD involves the three areas of environment, economy and society, with a focus on the relationships between environmental protection and human development. Education for sustainable development (ESD) takes a holistic view on the environmental, economic and social dimensions of SD and aims to empower students to engage in the democratic development of society in a more sustainable direction. Policy-level and research community discussions have addressed the ways in which ESD has been implemented internationally. This study focuses on upper secondary students, and investigates their views on sustainability and the ways they make decisions related to SD. The study aims to address the interdisciplinary and multidimensional content embraced in the concept of SD and the development of competences often associated with ESD. A survey investigating students’ (n=638) sustainability consciousness (SC) and their decision-making in a number of SD related contexts was conducted in 15 Swedish upper secondary schools. The results show that students attending schools with an ESD profile are characterized by stronger SC than students attending regular schools; however the difference is small and mostly related to the economic dimension of SD. Furthermore, students who prioritize environmental decisions in SD dilemmas show stronger SC than students giving priority to economic reasons. When environmental, economic and social dimensions are introduced separately, social aspects are given the highest priority by the students. In contrast, environmental aspects are up-graded when the dimensions are introduced in an integrated manner. However, different dimensions are prioritized in different contexts. The study provides empirical support for using multiple contexts and including both harmonious and conflict-based perspectives on SD in education. It also contributes knowledge to the discussion about the implementation of ESD in Sweden in terms of outcomes among students.

    Separated and integrated perspectives on environmental, economic, and social dimensions – an investigation of student views on sustainable development2015In: Environmental Education Research, ISSN 1350-4622, E-ISSN 1469-5871Article in journal (Refereed)
    Abstract [en]

    The sustainable development (SD) concept is based on the idea that economic and social development should be linked to the environment. However, controversies about various associated issues often arise due to the differences in protagonists’ viewpoints, depending partly on whether they focus mainly on environmental, economic, or social dimensions and partly on ideological stances related (for instance) to the optimal ways of promoting economic growth and social justice. This study investigates views of 638 Swedish upper secondary students who responded to a questionnaire probing their views of SD from two perspectives. In the first, the dimensions were separately introduced, so the respondents only had to consider one dimension at a time. In the second, the dimensions were introduced in an integrated fashion, so the respondents had to consider effects related to all three dimensions. The results strongly indicate that the students’ views and priorities concerning the dimensions depend on both the perspective and the context. Implications for teaching and learning are discussed.

    The implementation of education for sustainable development in Sweden: Investigating the sustainability consciousness among upper secondary students2014In: Research in Science & Technological Education, ISSN 0263-5143, Vol. 32, no 3, 318-339 p.Article in journal (Refereed)
    Abstract [en]

    Background: Sustainable development (SD) is a complex idea, based on environmental, economic and social dimensions. In line with SD, education for sustainable development (ESD) is an approach to teaching that combines cognitive and affective domains and aims to build empowerment abilities.

    Purpose: The purpose of this article is to investigate effects of the implementation of ESD in Sweden, in terms of developing students’ sustainability consciousness (SC). Two groups of students were included: one was from schools with a profile of ESD and the other one was from comparable schools without explicit ESD-profile.

    Sample: A total of 638 students from upper secondary schools (grade 12) in science-related or social science-related programs participated in the study.

    Design and methods: A procedure was created for the selection of schools considered to be the most active in using an ESD approach as well as comparable schools with no explicit ESD approach. During spring 2013, the students responded to a questionnaire based on sustainability knowingness, attitudes and behaviors within the environmental, economic and social dimensions of SD that together constitute the concept of SC. Data were analyzed using SPSS software.

    Results: The results indicate that there are significant differences in SC between students from schools that teach with an ESD approach compared to students from regular schools. Furthermore, a significant difference between the two groups of students was found in the underlying economic dimension of SC. No significant differences were found in the environmental and social dimensions of SC.

    Conclusions: Although the results show that ESD-profiled schools have effect on students' SC, the effects are relatively small. Therefore, the effects and nature of the implementation of ESD are discussed.

    Migrationof Atlantic salmon – conservation of a landlocked population in Sweden2013Conference paper (Refereed)
    Abstract [en]

    Populations of migratory salmon and trout have worldwide shown a decline due to human activities. Over the years numerous measures have been undertaken to maintain these populations, and conservation of migratory salmonids requires understanding of their ecology at multiple scales, combined with assessing anthropogenic impacts. The regulated River Klarälven and Lake Vänern host endemic populations of landlocked Atlantic salmon (Salmo salar) and brown trout (Salmo trutta). The historically high abundances of the salmonids in the River Klarälven in the early 1800s have decreased dramatically, reaching all-time lows after the completion of all nine Swedish hydroelectric power stations in the 1960s. After an extensive stocking program and transportation of wild and hatchery-raised spawners past eight hydroelectric plants, catches from commercial, maintenance and sport fishing have again increased. Recently, increases in the proportion of wild salmon returning to the River Klarälven have generated interests in establishment of wild salmon inhabiting the entire River Klarälven, including upstream of the Norwegian border. To obtain information needed to produce a management plan for the salmon, we conducted a number of studies of upstream-migrating spawners and downstream-migrating smolts. For upstream migration, we compared migration behaviour of wild and hatchery reared salmon and found that wild fish swam directly to the spawning grounds and presumably spawned, whereas few salmon of hatchery-origin arrived at the spawning grounds, and if they did so they swam considerably more before settling down at the spawning grounds. Studies of smolt showed that only 16% of the salmon passed all eight dams, and that losses in the dam-free lower 25 km of the river, before the salmon enter the lake, were higher for hatchery-raised smolts than for wild smolt. These differences between wild and hatchery-reared salmon underline the importance of increasing the number of wild salmon in the system and indicate that remedial measures are needed to improve passage success.

    Lax och öring i Klarälven - möjligheter för vild fisk och kvalité på odlad fisk: Slutrapport 2008-20122013Report (Other academic)
    Abstract [sv]

    Data från 1800-talet visar att fångsterna av lax och öring i både älv och sjö varit mycket högre än idag. Storskaliga dämmen, kraftigt fiske i Dejeforsen, nio kraftverk i den svenska delen av Klarälvens huvudfåra, och användandet av älven för timmerflottning har bidragit till detta. Efter att utsättning av kompensationsodlad fisk startade ökade fångsten igen, även om den fortfarande är låg.

    Fältundersökningar av vild laxsmolt visade att 16 % av smolten klarade sig hela vägen förbi de åtta kraftverken mellan Edebäck och Forshaga. Under studien var vattenföringen, och därmed spillet, lågt, vilket troligen bidragit till de höga förlusterna. Normalt spills det inte under hela smoltvandringsperioden, vilket är olyckligt.

    Lax och öring uppfödda under normala odlingsförhållanden är oftast större och fetare än vild fisk. Vi födde upp lax med olika fodertyper och fodermängder. Mängden föda påverkade laxens tillväxt och smoltmognad, och lax som fått fettfattigt foder var mest ”naturlik”. Den klarade också vandringen bäst, 80 % tog sig till Vänern medan 55 % av laxen som fått normalt eller lite foder. Bara 20 % av tidigt könsmogna hanar tog sig till Vänern.

    Rapporten avslutas med implikationer och förslag till åtgärder och fortsatta studier.

    Atlantic salmon and brown trout in Lake Vänern: A proposal for a co-management system2014In: Aquatic Ecosystem Health & Management, ISSN 1463-4988, E-ISSN 1539-4077, Vol. 17, no 4, 365-373 p.Article in journal (Refereed)
    Abstract [en]

    Co-management is of increasing interest for fisheries management. We explore possibilities for, and barriers to, developing a co-management system, using threatened populations of landlocked Atlantic Salmon and Brown Trout as examples. Good management of natural resources requires not only knowledge about the resource but also suitable tools to collect information and make decisions. In large ecosystems this can be difficult because many actors are involved, and various societal borders and traditions become barriers. Vänern is the largest lake in the EU and it holds several distinct populations of large-bodied landlocked Atlantic Salmon and Brown Trout. The lake is used for commercial, subsistence, and sport fishing as well as for other recreational activities, and in Klarälven, the largest river entering Vänern, sport fishing is popular. These salmonid populations were at critically low levels during the 1960s, but a stocking program since then has maintained the fishery, and at least one wild stock appears to be recovering since being protected in 1993. Ecosystem users all have different needs: in the lake, sport fishermen say that catches of hatchery fish have declined, and commercial fishermen have focused on other species. In the river, wild salmon may be recovering: sport fishing is popular and an ongoing project investigates the possibilities for salmon to be able to circumvent hydro-electrical plants and reach historical Norwegian spawning areas. Not only do we lack information about the salmonids’ different life stages, we also lack a suitable socio-political organization to find sustainable solutions to the different needs of diverse user groups. We argue that a co-management system that enfranchises user groups in the Vänern-Klarälven ecosystem will improve sustainable management of wild and hatchery fish.

    Är människor också djur?: Djurvälfärd betraktat från två olika ideologiska perspektiv2014Independent thesis Basic level (degree of Bachelor), 180 HE creditsStudent thesis
    Abstract [sv]

    Djurhållning inom livsmedelsindustrin är ett stort problem, både ur miljösynpunkt men även när det kommer till djurvälfärd. I den här studien undersöks hur ekologisk djurhållning och djurrättsaktivism kan fungera tillsammans för att nå en god djurvälfärd utifrån de ideologier som ligger till grund för dessa inriktningar. För att ta reda på detta valdes två organisationer ut för att representera vardera sida, KRAV och Djurens Rätt, och sedan identifierades de bakomliggande ideologierna. Det utvalda materialet, som består av publikationer från respektive organisation, bearbetades med hjälp av en diskursanalys, som ger utrymme för egna tolkningar och reflektioner. Målet för studien har inte varit att nå en definitiv sanning, utan att presentera nya synsätt och bidra med nya perspektiv i frågan. I diskussionen framkommer att det är antropocentriska ideologier somligger till grund för KRAV och icke-antropocentriska ideologier som ligger bakom Djurens Rätt. Dessa kombineras sedan med ett feministiskt perspektiv för att utveckla diskussionen ytterligare. Slutsatser som dras är att KRAV och Djurens Rätt strävar efter samma sak, nämligen en god djurvälfärd, problematiken ligger i de bakomliggande ideologierna. En icke-antropocentrisk ideologi kan inte godta att djur dödas för mänskliga syften, men enligt antropocentrismen finns djuren till för människans nytta och rättfärdigar detta, vilket starkt antyder att de inte kan kombineras. Genom att lägga till det feministiska perspektivet finns dock möjligheten att sträva efter samexistens, där djur och människor lever jämte varandra på samma villkor. Det är inte en lösning, men det kan öppna upp för nya sätt att betrakta hur människor kan göra djurvälfärd till en naturlig del av att vara vid liv.

    Clonality increases with snow depth in the arctic dwarf shrub Empetrum hermaphroditum.2016In: American Journal of Botany, ISSN 0002-9122, E-ISSN 1537-2197, Vol. 103, no 12, 2105-2114 p.Article in journal (Refereed)
    Abstract [en]

    PREMISE OF THE STUDY: Vegetative reproduction and spread through clonal growth plays an important role in arctic-alpine ecosystems with short cool growing seasons. Local variation in winter snow accumulation leads to discrete habitat types that may provide divergent conditions for sexual and vegetative reproduction. Therefore, we studied variation in clonal structure of a dominant, evergreen, dwarf shrub (Empetrum nigrum s.l. with the two taxa E. nigrum L. s.s. and E. hermaphroditum Hagerup) along a snow cover gradient and compared clonal diversity and spatial genetic structure between habitats.

    METHODS: We studied 374 individual shoots using 105 polymorphic AFLP markers and analyses based on hierarchical clustering, clonal diversity indices, and small-scale spatial genetic structure with pairwise kinship coefficient. We used two approaches to define a threshold of genotypic distance between two samples that are considered the same clone. Clonality was examined among three habitats (exposed ridges, sheltered depressions, birch forest) differing in snow conditions replicated in four study regions in Norway and Sweden.

    KEY RESULTS: Clonality of E. hermaphroditum differed between habitats with an increase in clonal diversity with decreasing snow depth. Small-scale spatial genetic structure increased with decreasing clonal diversity and increasing clone size. In three study regions, E. hermaphroditum was the only species, whereas in one region E. nigrum also occurred, largely confined to exposed ridges.

    CONCLUSIONS: Our results demonstrated that snow cover in conjunction with associated habitat conditions plays an important role for the mode of propagation of the dwarf shrub E. hermaphroditum.

    Synchronous flowering despite differences in snowmelt timing among habitats of Empetrum hermaphroditum2015In: Acta Oecologica, ISSN 1146-609X, E-ISSN 1873-6238, Vol. 69, 129-136 p.Article in journal (Refereed)
    Abstract [en]

    The topography within arctic-alpine landscapes is very heterogeneous, resulting in diverse snow distribution patterns, with different snowmelt timing in spring. This may influence the phenological development of arctic and alpine plant species and asynchronous flowering may promote adaptation of plants to their local environments.We studied how flowering phenology of the dominant dwarf shrub Empetrum hermaphroditum varied among three habitats (exposed ridges, sheltered depressions and birch forest) differing in winter snow depth and thus snowmelt timing in spring, and whether the observed patterns were consistent across three different study areas.Despite significant differences in snowmelt timing between habitats, full flowering of E. hermaphroditum was nearly synchronous between the habitats, and implies a high flowering overlap. Our data show that exposed ridges, which had a long lag phase between snowmelt and flowering, experienced different temperature and light conditions than the two late melting habitats between snowmelt and flowering.Our study demonstrates that small scale variation seems matter less to flowering of Empetrum than interannual differences in snowmelt timing.

    Föräldrars syn på barns säkerhet: En kvalitativ studie2014Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A paradigm shift is proposed in the literature regarding child safety, from keeping the children as safe as possible to keeping the children as safe as necessary. This could be a way to satisfy children’s need of challenges in order to thrive and their need for safety. In relation to such an ongoing change it is of value to investigate how parents, as guardians, perceive child safety at home and in preschool. The purpose of this study is to research parental perception of child safety in the home environment and childcare. The study is also concerned with how parents perceive their influence over the risks and risk assessments surrounding the children at home and in preschool. Semi-structured qualitative interviews were conducted with parents of preschool children and a qualitative content analysis was used. The results show that safety to a big extent is sees as protective measures to safeguard children from risk. Risks in the physical environment were discussed in relation to the home environment and preschool and psychological and social risks were discussed in relation to preschool, relationships amongst peers and the society. The parents see themselves as having a significant influence over risks in the home environment and to a lesser degree in relation to peers and preschool. Parents voice a constant need for balancing between safety, risks and other factors such as development, independence, and social acceptance. Adults constantly analyze risk to make appropriate decisions to safeguard the children. The informants describe supervision as crucial to keep children safe. To conclude, the results indicate a need for improved communication between parents and preschool staff regarding evaluations between safety and other factors, like development and positive challenges that help children to thrive. Suggestions for future research are given.

    Det moderna risksamhället: En studie om klimatrisker inom kommunal krisberedskap2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Climate change is now a phenomenon we cannot ignore. It is happening here and now and there is more or less common scientific consensus that so is the case. With climate change come risks that are difficult to predict and to relate to and this affects the integration of these risks in the municipal emergency preparedness. The purpose of the study is to examine the factors that are affecting the integration of climate risks in the municipal emergency preparedness. The result is based on a number of interviews conducted with people working with municipal activities and a Municipal Council. The responses have been more or less clear that the largest factors affecting the integration of climate risks in the municipal emergency preparedness is scientific uncertainty and how this is mediated by international organizations, the fact that there is a common lack of knowledge about the effects that may arise from climate change and that there is also a lower awareness of many of the risks in general. In addition, different effects are differently prioritized which affects the integration of all risks associated with climate change. I have also conducted a document analysis to give further substance to the results I found.

    Ny konsumtion av gamla kläder: – En studie om konsumenters miljömedvetenhet och motiv till att köpa second hand kläder på Myrorna2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The world’s consumption is increasing at an accelerating rate and it´s produced and consumed more goods and services than ever before. A large part of people's consumption consists of clothing that is bought and discarded increasingly leading to a number of environmental problems such as global warming, pollution, loss of biodiversity and the depletion of natural assets. One way to save the earth's resources is to buy used clothing, so called second hand, instead of new ones. The store chain “The Ants” (in Swedish “Myrorna”) has specializing in second-hand goods and sells, among other things, clothes. This study examined consumers' motive for shopping second-hand clothing on The Ants and examined whether this is related to consumers' environmental awareness and their choice to buy second hand clothes on The Ants. The shop staffs experience of the customer's environmental awareness was also examined. The methods that were chosen were surveys that The Ants customers filled out and interviews with store employees.

    The results showed that consumer´s motive to buy second-hand clothing on The Ants was mainly due to the cheap price and then because of their environmental awareness, customers were relatively environmentally aware and knew that the clothing industry contribute to environmental problems. The consumers felt that they received too little information about the problems and they would like to know more. The result also showed that consumers don´t act according to this awareness as very few of them asked questions to the staff about their clothing production or work with sustainable consumption and the environment. The Ants shop staff experienced the same thing since they rarely or never received any questions from customers about clothing and its environmental problems. Customers also bought more new clothes than second-hand clothing.

    Effekt av berikad vs standard odlingsmiljö på beteende och tillväxt hos lax2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

     ABSTRACT

    The farming of salmon in hatcheries has been used to compensate for the decline of many wild populations due to human activity. Recent evidence has indicated that standard farmed salmon have a  higher mortality than wild fish, leading to the question of whether hatchery conditions can be altered to improve survival of stocked salmon. The purpose of this study was to compare the behavior and growth of hatchery-raised Atlantic salmon (Salmo salar) raised under standard conditions vs varied (enriched) hatchery conditions. The hypothesis was that fish from enriched rearing would grow faster, presumably due to more efficient foraging, resulting in less total movement, In addition, I predicted that salmon from enriched conditions would  have a higher biomass of food in their stomachs than fish reared under standard conditions. Salmon from the two different groups, enriched and standard, were held separate during their first 12 months of life. The following nine months the fish were raised together in semi-natural outdoor tanks. Behavior and growth of the fish were measured during this latter period. The results showed no support for my hypotheses. Biomass of food contents and summer and winter growth did not differ between treatments. I did find, however, that fish farmed in enriched environments were more active during the summer than fish raised under standard conditions. This suggests that early rearing conditions affect the behavior of the fish, but it is unclear if this effect has any bearing on survival of the fish when stocked in rivers.

    The Effectiveness of Education for Sustainable Development2015In: Sustainability, ISSN 2071-1050, E-ISSN 2071-1050, Vol. 7, no 11, 15693-15717 p.Article in journal (Refereed)
    Abstract [en]

    Perhaps the most important issue in our time is how to sustain our planet's resources, while developing wealth and well-being for a growing population. This monumental task has been defined in the concept of sustainable development (SD). During the last few decades the world communities have agreed upon addressing SD through international treaties. As a response Education for Sustainable Development (ESD) has been launched as an answer to cope with sustainability. However, empirical studies are a missing link in the discourse around ESD, where decisions and implementation strategies are heavily based on policy recommendations and gut feelings by practitioners. We used data from 2413 students in grades 6, 9, and 12 from 51 schools across Sweden to study the effectiveness of ESD. In line with the current debate on the definition of ESD, we quantified the extent to which teaching can be labeled as holistic and/or pluralistic. Through a series of descriptive analyses and the estimation of structural equation models, our results indicate that ESD can indeed impact on student outcomes in terms of their sustainability consciousness. The results of this study reveal the key role ESD plays in addressing SD, paving the way for a more sustainable future.

    Strategies for mitigating the impact of hydropower plants on the stocks of diadromous species in the Daugava River2016In: INTERNATIONAL SCIENTIFIC CONFERENCE - ENVIRONMENTAL AND CLIMATE TECHNOLOGIES, CONECT 2015 / [ed] Valtere, S, ELSEVIER SCIENCE BV , 2016, 81-88 p.Conference paper (Refereed)
    Abstract [en]

    The Daugava River is the largest river in Latvia. Daugava Hydro Power Plants built in 1939 - 1974 are Latvia's most important renewable resource in generation of electricity. The absence of fish passage structures excludes upstream migration of diadromous species. Compensatory stocking activities are introduced annually. The need for studying alternative or additional impact mitigation measures is based on biodiversity conservation aspects and possible changes in EU legislation. The case study of solutions for improving the Daugava River connectivity is introduced and further strategies for mitigating the impact of HPP are proposed in the paper.

    Assessing the effects of societal injury control interventions2016Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Injuries have emerged as one of the biggest public health issues of the 21th century. Yet, the causal effects of injury control strategies are often questioned due to a lack of randomized experiments. In this thesis, a set of quasi-experimental methods are applied and discussed in the light of causal inference theory and the type of data commonly available in injury surveillance systems. I begin by defining the interrupted time series design as a special case of the regression-discontinuity design, and the method is applied to two empirical cases. The first is a ban on the sale and production of non-reduced ignition propensity (RIP) cigarettes, and the second is a tightening of the licensing rules for mopeds. A two-way fixed effects model is then applied to a case with time-varying starting dates, attempting to identify the causal effects of municipality-provided home help services for the elderly. Lastly, the effect of the Swedish bicycle helmet law is evaluated using the comparative interrupted time series and synthetic control methods. The results from the empirical studies suggest that the stricter licensing rules and the bicycle helmet law were effective in reducing injury rates, while the home help services and RIP cigarette interventions have had limited or no impact on safety as measured by fatalities and hospital admissions. I conclude that identification of the impact of injury control interventions is possible using low cost means. However, the ability to infer causality varies greatly by empirical case and method, which highlights the important role of causal inference theory in applied intervention research. While existing methods can be used with data from injury surveillance systems, additional improvements and development of new estimators specifically tailored for injury data will likely further enhance the ability to draw causal conclusions in natural settings. Implications for future research and recommendations for practice are also discussed.

    Searching for causal effects of road traffic safety interventions: applications of the interrupted time series design2015Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Traffic-related injuries represent a global public health problem, and contribute largely to mortality and years lived with disability worldwide. Over the course of the last decades, improvements to road traffic safety and injury surveillance systems have resulted in a shift in focus from the prevention of motor vehicle accidents to the control of injury events involving vulnerable road users (VRUs), such as cyclists and moped riders. There have been calls for improvements to the evaluation of safety interventions due to methodological problems associated with the most commonly used study designs. The purpose of this licentiate thesis was to assess the strengths and limitations of the interrupted time series (ITS) design, which has gained some attention for its ability to provide valid effect estimates. Two national road safety interventions involving VRUs were selected as cases: the Swedish bicycle helmet law for children under the age 15, and the tightening of licensing rules for Class 1 mopeds. The empirical results suggest that both interventions were effective in improving the safety of VRUs. Unless other concurrent events affect the treatment population at the exact time of intervention, the effect estimates should be internally valid. One of the main limitations of the study design is the inability to identify why the interventions were successful, especially if they are complex and multifaceted. A lack of reliable exposure data can also pose a further threat to studies of interventions involving VRUs if the intervention can affect the exposure itself. It may also be difficult to generalize the exact effect estimates to other regions and populations. Future studies should consider the use of the ITS design to enhance the internal validity of before-after measurements.

    Injury risks in schoolchildren with attention-deficit/hyperactivity or autismspectrumdisorder: Results from two school-based health surveys of 6- to 17-year-old children in Sweden2016In: Journal of Safety Research, ISSN 0022-4375, E-ISSN 1879-1247, Vol. 58, 49-56 p.Article in journal (Refereed)
    Abstract [en]

    Introduction: Injuries are one of the leading causes of death and disability among children in Sweden and attention-deficit/hyperactivity disorder (ADHD) has previously been associated with an increased risk of injury in pediatric populations elsewhere in the world. Current evidence regarding the possible link between autism spectrum disorder (ASD) and injury risk appears limited, even though some potentially risk-increasing symptoms overlap. The purpose of this study was thus to study the association between both ADHD and ASD concerning the risk of injury among Swedish schoolchildren. Methods: Two samples were used: a population based register study containing data from 18,416 children ranging from the ages of 6-17 years collected by school nurses during 2012/2014 (Survey A), and a national cross-sectional study of 3202 ninth-grade children (similar to 15 years old) collected from 92 schools in 2011 (Survey B). The data were analyzed using chi(2)-tests and log binomial generalized linear models to obtain risk ratios (RR), comparing cases reportedly affected by ADHD or ASD to unaffected controls. Results: After adjusting for confounders, ADHD was associated with a 65% increased risk of injury (RR 1.65 [95% CI: 132-2.05] in Survey A, and a 57% increased risk of injury (RR 1.57 [95% CI: 1.27-1.95]) in Survey B. ASD was not significantly associated with any differences in injury risk (RR 0.81 [95% CI: 0.57-1.14]). Conclusions: The results indicate that there is an elevated injury risk among Swedish schoolchildren with ADHD but not for children with ASD. Future studies should focus on causal mechanisms mediating the association between ADHD and injuries in order to facilitate injury prevention strategies. Practical applications: Parents and teachers of schoolchildren with ADHD should be made aware of the elevated injury risks associated with the diagnosis. Safety experts and injury control professionals should consider the development of specialized prevention strategies in order to reduce these risks.

    Evidensbaserade åtgärder för cyklisters säkerhet: kunskapsöversikt2013Report (Other academic)
    Abstract [sv]

    Att cykla förespråkas ofta av hälso-, miljö- och framkomlighetsskäl, men är samtidigt ett av de farligare transportmedlen utifrån ett skadeperspektiv. För att cyklismen ska kunna utvecklas hållbart krävs därmed även att fokus läggs på säkerhetsaspekten vid policybeslut som syftar till att öka cyklandet. Syftet med denna rapport är att återge en samlad bild av det vetenskapliga kunskapsläget när det gäller säkerhetsfrämjande åtgärder för cyklister.

    Cykelhjälmar är ett välbeforskat ämne inom detta område och evidensen pekar relativt entydigt att hjälmar ger ett bra skydd mot huvud- och hjärnskador. Vissa studier har även uppmätt en skyddande effekt mot ansiktsskador, men detta har på senare tid delvis ifrågasatts. En ytterligare aspekt som har belysts är om dagens mjukare cykelhjälmar ger ett lika bra skydd som hjälmar med hårdare skal, som var vanligare förr. Denna hypotes har hittills varken kunnat styrkas eller förkastas, bl a till följd av att man inte registrerar hjälmtyp inom sjukvården. Cykelhjälmslagstiftning är ett annat kontroversiellt ämne där det har hävdats att hjälmlagarna som infördes i Australien och Nya Zeeland på 1990-talet avskräckte människor från att cykla, med åtföljande negativ effekt på folkhälsan till flöjd av minskad motion. Ingen stark evidens för denna hypotes har hittats, och det verkar för övrigt som att cykelhjälmslagar har haft en reducerande effekt på antalet cykelrelaterade huvudskador i de länder som har lyckats implementera dem på ett sätt som faktiskt ökar hjälmanvändningen i populationen. Effekten förefaller dock kulturellt betingad, och skillnader i bötesavgift eller risken att bli bötfälld är troligtvis av stor betydelse. Utbildning och ekonomiska styrmedel kan fungera som alternativ till lagstiftning, men evidensen för att utbildning verkligen ökar hjälmanvändningen är svag. Gällande ekonomiska styrmedel pekar evidensen mot att gratis hjälmutdelning är det som fungerar bäst. Större satsningar på samhällsnivå verkar fungera bättre än hjälmprogram som inriktar sig på skolor.

    När det gäller åtgärder för trafikmiljön är evidensen inte helt entydig, men det verkar som att fysiskt separerade cykelbanor är att föredra framför cykelfält (ett fält för cyklister på vägen, avgränsas med en spärrlinje). Fysiskt separerade cykelbanor kan dock vara mer problematiska i väjningsreglerade korsningar, vilket kan bero på att bilister inte uppmärksammar cyklister på samma sätt som när ett cykelfält finns anlagt på sidan av vägbanan. Detta ökar behovet av säkra cykelöverfarter och när det gäller sådana förefaller förhöjda cykelöverfarter fungera bättre än färgmarkerade överfarter. Olycksrisken på kombinerade gång- och cykelvägar bör inte förväxlas med olycksrisken på cykelspecifika banor, och ytterligare forskning behövs för att avgöra effekten av kombinerade banor. Rondeller verkar vara problematiska för cyklister om det inte finns en fysiskt separerad cykelbana i anslutning till dem. Övriga åtgärder som har uppvisat en positiv effekt är belysning på landsbygdsvägar, refuger i bostadsområden och dynamiska hastighetsskyltar i skolzoner.

    Intressant nog ser det ut att finnas få studier som har försökt mäta effekten av synbarhetsökande medel (t.ex. reflexer) med tillförlitliga utvärderingsmått (skaderisk eller olycksrisk). Att montera varselljus på cykeln som går igång automatiskt och inte kan kontrolleras av cyklisten verkar dock minska risken för kollisionsolyckor under dagtid.

    Även allmän cykelsäkerhetsutbildning i skolar har undersökts. Av de få studier som använt tillförlitliga utvärderingsmått har ingen kunnat uppvisa en positiv effekt. Fler studier behövs för att bedöma effekten av sådana åtgärder innan utbildning kan rekommenderas med starkt vetenskapligt stöd.

    Can the provision of a minor home help service for the elderly population reduce the incidence of fall-related injuries?: A quasi-experimental study of the community-level effects on hospital admissions in Swedish municipalities2016In: Injury Prevention, ISSN 1353-8047, E-ISSN 1475-5785Article in journal (Refereed)
    Abstract [en]

    Background

    Fall-related injuries are a global public health problem, especially in elderly populations. The effect of an intervention aimed at reducing the risk of falls in the homes of community-dwelling elderly persons was evaluated. The intervention mainly involves the performance of complicated tasks and hazards assessment by a trained assessor, and has been adopted gradually over the last decade by 191 of 290 Swedish municipalities.   

    Methods

    A quasi-experimental design was used where intention-to-treat effect estimates were derived using panel regression analysis and a regression-discontinuity (RD) design. The outcome measure was the incidence of fall-related hospitalizations in the treatment population, the age of which varied by municipality (≥65 years, ≥67 years, ≥70 years or ≥75 years).

    Results

    We found no statistically significant reductions in injury incidence in the panel regression (IRR 1.01 [95% CI: 0.98-1.05]) or RD (IRR 1.00 [95% CI: 0.97-1.03]) analyses. The results are robust to several different model specifications, including segmented panel regression analysis with linear trend change and community fixed effects parameters.

    Conclusions

    It is unclear whether the absence of an effect is due to a low efficacy of the services provided, or a result of low adherence. Additional studies of the effects on other quality of life measures are recommended before conclusions are drawn regarding the cost-effectiveness of the provision of home help service programs.

    The effect of the Swedish bicycle helmet law for children: An interrupted time series study2014In: Journal of Safety Research, ISSN 0022-4375, E-ISSN 1879-1247, Vol. 51, 15-22 p.Article in journal (Refereed)
    Abstract [en]

    Previous population-based research has shown that bicycle helmet laws can reduce head injury rates among cyclists. According to deterrence theory, such laws are mainly effective if there is a high likelihood of being apprehended. In this study, we investigated the effect of the Swedish helmet law for children under the age of 15, a population that cannot be fined. Method  An interrupted time series design was used. Monthly inpatient data on injured cyclists from 1998–2012, stratified by age (0–14, 15 +), sex, and injury diagnosis, was obtained from the National Patient Register. The main outcome measure was the proportion of head injury admissions per month. Intervention effect estimates were obtained using generalized autoregressive moving average (GARMA) models. Pre-legislation trend and seasonality was adjusted for, and differences-in-differences estimation was obtained using adults as a non-equivalent control group. Results There was a statistically significant intervention effect among male children, where the proportion of head injuries dropped by 7.8 percentage points. There was no evidence of an intervention effect on the proportion of head injuries among female children. Conclusion According to hospital admission data, the bicycle helmet law appears to have had an effect only on male children.

    Subject- and experience-bound differences in teachers' conceptual understanding of sustainable development2014In: Environmental Education Research, ISSN 1350-4622, E-ISSN 1469-5871, Vol. 20, no 4, 526-551 p.Article in journal (Refereed)
    Abstract [en]

    This article describe the results of a nationwide questionnaire study of 3229 Swedish upper secondary school teachers’ understanding of sustainable development in relation to their subject discipline and teaching experience. Previous research has shown that teachers have difficulties understanding the complex concept of sustainable development. According to the Swedish curriculum all teachers in all subjects should integrate a holistic perspective of sustainable development including economic, ecological and social dimensions. This study shows that teachers differ in their understanding of the concept mostly according to their subject traditions. Social science teachers emphasize social dimensions, and science teachers’ ecological dimensions, respectively. Teachers are aware of the relevance of the three dimensions to various degrees, but do not generally have a holistic understanding. The greatest uncertainty in teachers’ understanding is related to the economic dimension. Science and social science teachers are critical of incorporating economic growth into the concept of sustainable development while language, vocational and esthetical-practical teachers are not. No experience-bound differences of the teachers’ understanding could be found, but recently qualified teachers consider their understanding of sustainable development to be poorer in comparison to more experienced teachers’ self-evaluation. The study highlights the need for further training in sustainable development since more than 70 % of the questioned teachers stated that they need such training.

    Integrering av risk- och sårbarhetsanalys och klimatanpassning i fysisk planering: En kvalitativ fallstudie av Bergen kommune2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    During the last decades Risk and vulnerability analysis and Climate Change Adaptation (CCA) have gained focus in the public arena. Science have been directed towards how public actors run, plan, and work with Risk and vulnerability analysis, CCA, and climate change(Granberg & Elander, 2007; Hjerpe & Glaas, 2012; Storbjörk, 2007).Local authorities both in Sweden and Norway are obligated to carry out risk and vulnerability analyses. These analyses often make suggestions for actions that may reduce vulnarability for the risks identified by the analysis, as well as increase the organizations’ ability to cope. In many cases, theses actions involves several departments within or between actors at the local level, which contributes to emphasize the need to integrate the result of the analyses in all activities at the local level. Spatial planning is an important tool to adapt society towards different or new types of risks, often intertwined with the consequences of a different climate. All stages in the process of planning and building and spatial planning must collaborate with other sectors within the organizations in order to contribute to building a society with a holistic perspective.When risk and vulnerability analysis and CCA are integrated in local descision-making processes, significant barriers may occur. Authorities are often seen as key factors both to create, but also to to identify and desolve these barriers. Institutional challenges during the integration and adaptation process often occur.Different tools and guides have been developed to systematically analyze barriers that may affect the adaptation process. By using such a guide, Wamsler’s ”Integration of climate change adaptation in local management and planning – a guide”, a case study is made on Bergen kommune’s integration of risk and vulnerability analysis and CCA in spatial planning processes. The integration process is analyzed by help of a guide. The application of such guides and its use are then discussed.The study concludes that Bergen kommune has come a long way in its integration process, based on the criterias presented in Wamsler’s guide. The process focuses around the integration of risks and vulnerabilities in an instrument developed by the department of spacial planning which is constituted by an interactive map of the municipalities’ area and physical environment. This instrument seems to meet the demands made by Norwegian authorities on integrating risk and vulnerability analysis and CCA well. There were no barriers identified in the process by the use of Wamsler’s guide, however, there emerged signs of possible barriers through the interviews made with employees for this study. These barriers seem to exist within the division of responsibilities and collaboration within different organizational units of the municipality.The study supports earlier research which confirms that there are challenges with using these types of tools and guides to analyze integration and adaptation processes. A clear aim and a background to what the tool or guide is meant to do and why, as well as help and guidance to handle barriers identified in the process of analyzing, are crucial for how well the guide can be of help for an organization going through a process of adaptation and integration.

    Att vara efterklok på förhand: En kvalitativ studie om hur man ser på krisplaner inom den privata sektorn2013Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Kriser och allvarliga händelser sker på svenska företag varje år. Krisplanernas förekomst inom privata företag är låg jämfört med den offentliga sektorn, vilket kan medföra att kriberedskapen hos privata företag inte är så god som den skulle kunna vara. Syftet med denna studie är att fånga uppfattningen av hur man på olika nivåer i privata företag beskriver förekomst, användande och implementering av krisplaner. De roller som studien undersöker är chef, mellanchef samt medarbetare. Totalt har sju stycken kvalitativa intervjuer genomförts och analyserats utifrån innehållsanalys med meningsbärande enheter, koder och kategorier. Resultatet i studien visar att användning och framkomst av krisplaner skiljer sig mellan företagen. Den största skillnaden syns dock utifrån företagets storlek och antal anställda, då bland annat ekonomi och juridik styr prioritering av säkerhetsarbetet. Även företagets risknivåer påverkar inställningen till att arbeta med krisplaner, då vissa branscher ses som mer skadedrabbade än andra.

    Plötsligt händer det: En kvalitativ studie om krishantering inom den privata sektorn2014Independent thesis Advanced level (degree of Master (Two Years)), 80 credits / 120 HE creditsStudent thesis
    Abstract [sv]

    Dödsfall, arbetsplatsolyckor, hot och våld. Alla är de exempel på kriser som inträffar på svenska företag varje år. Dessa händelser ställer krav på att företagen har en organisation och struktur för att klara av att hantera kriserna och för att minska verkningarna av dem. Krishantering är ett samlingsbegrepp för hur man systematiskt arbetar för att minska krisens omfattning, både före, under och efter att den har inträffat. Syftet med att använda krishantering är att företagen skall kunna förebygga att allvarliga händelser inträffar och att hantera dem på ett effektivt sätt.

      Ungefär sju av tio svenska företag har idag etablerad krisberedskap som gör att de klarar av att hantera kriser och olyckor, men lagstiftningen ställer krav att alla företag skall planera och organisera krisstöd och krishantering oavsett verksamhetsområde och bransch.

    Syftet med denna studie är att undersöka hur chefer i privata företag beskriver krishantering inom sina verksamheter och hur man ser på prioritering av krishanteringen. Studien undersöker även huruvida det anses viktigt med utbildning för att skapa förutsättningar för att bedriva ett gott krishanteringsarbete. Totalt har fyra stycken kvalitativa intervjuer genomförts med chefer i privata företag och organisationer. Intervjuerna har sedan analyserats utifrån innehållsanalys med meningsbärande enheter, koder, kategorier samt underkategorier.

     Resultatet i studien påvisar stora skillnader mellan större och mindre företag, där de större företagen har etablerade krisorganisationer med rutiner och arbetssätt som gör att de på ett effektivt sätt kan hantera allvarliga händelser. De mindre företagen saknar krisberedskap helt och hållet och saknar många gånger information och kunskap om hur de skall tolka och applicera lagtext på området.
