    Inclusive Early Childhood Education Environment Self-Reflection Tool2017Collection/Antologi (Annet vitenskapelig)
    Abstract [en]

    From Introduction:

    This Self-Reflection Tool was developed as part of the Inclusive Early Childhood Education (IECE) project, conducted by the European Agency for Special Needs and Inclusive Education from 2015 to 2017 (www.european-agency.org/agency-projects/inclusive-earlychildhood-education). The project’s overall goal was to identify, analyse and subsequently promote the main characteristics of quality IECE for all children. To that end, a need was detected for a tool that all professionals and staff could use to reflect on their setting’s inclusiveness, focusing on the social, learning and physical environment. This tool is intended to help improve settings’ inclusiveness.

    Ecology and evolution of coastal Baltic Sea 'dead zone' sediments2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Since industrialization and the release of agricultural fertilizers began, coastal and open waters of the Baltic Sea have been loaded with nutrients. This has increased the growth of algal blooms and because a portion of the algal organic matter sinks to the sea floor, hypoxia has increased. In conjunction to this, natural stratification of the water column makes the bottom zones especially prone to oxygen depletion due to microbes using oxygen and organic matter to grow. Hypoxia (<2 mg/L O2) and anoxia (no oxygen) are deadly for many organisms and only specialists (typically some microorganisms) are able to survive. Due to the harsh conditions these bottom zones are commonly referred to as 'dead zones'. The focus of this thesis was to look closer at the microbial community changes upon degradation of algal organic matter and the effect of oxygenating coastal Baltic Sea 'dead zone' sediments on chemistry fluxes, phyto- and zooplankton, the microbial community structure, and microbial metabolic responses. Results from field sampling and incubation experiments showed that degradation of algal biomass in nutrient rich oxic sediment was partly related to the growth of archaea; that oxygenation of anoxic sediments decreased stored organic matter plus triggered hatching of zooplankton eggs increasing the benthic-pelagic coupling; and resting diatoms buried in hypoxic/anoxic sediment were alive and triggered to germinate by light rather than oxygen. Changes in the microbial community structures to oxygen shifts were dependent on the historical exposure to oxygen and that microbial generalists adapted to episodic oxygenation were favored during oxygen shifts. Facultative anaerobic sulfur/sulfide oxidizing bacterial genera were favored upon oxygenation of hypoxic/anoxic sediment plus sulfur cycling and nitrogen fixation genes were abundant. Finally, it was discovered that oxygenation regulates metabolic processes involved in the sulfur and methane cycles, especially by metabolic processes that results in a decrease of toxic hydrogen sulfide as well as the potent greenhouse gas methane. This thesis has explored how 'dead zones' change and develop during oxygen shifts and that re-oxygenation of ‘dead zones’ could bring favorable conditions in the sediment surface for reestablishment of new micro- and macroorganism communities.

    Righting the writing. The power dynamic of Soviet Ukraine language policies and reforms in the 1920s-1930s2017Inngår i: Studi Slavistici, ISSN 1824-761X, E-ISSN 1824-7601, Vol. 14, 67-89 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Righting the Writing. The Power Dynamic of Soviet Ukraine Language Policies and Reforms in the 1920s-1930s The first post-revolutionary decades became decisive for the development of the Ukrainian language, national culture and identity. The Ukrainian language, previously subject to a number of bans, finally entered the stage of intensive status and corpus planning. Thanks to this, it became a decisive factor in the rivalry between different forms of statehood vying on the Ukrainian territory after 1917. At the same time, the status upgrade and broader public use called for the standardisation of the language. The first practical steps towards the unification of different orthographic traditions were undertaken from 1918 to 1921. The turbulence of civil war, however, determined the failure of comprehensive language reform. Calls for linguistic unification gained new force in the second half of the 1920s: with the introduction of Ukrainizacija, the local variant of the all-Union nationalities policy of korenizacija introduced in 1923, the Ukrainian language was acknowledged as the means to the republic’s Sovietisation. This was part and parcel of the Soviet "affirmative action empire" (Terry Martin) which had to contain the 1917-1921 rise of nationalism of the empire’s minorities. Locally, the elites had to negotiate their own interests and the centre’s demands. How exactly do the debates on the "correct" codification of the language and the actual steps towards different ideals reflect the changing power dynamic between the centre and the republics in the interbellum ussr This is the problem this study sets out to tackle using the example of Soviet Ukraine. The paper explores the link between language and politics in Soviet Ukraine in the 1920s and 1930s. While examining the political preconditions for the language policies in Ukraine, significant attention will also be devoted to the specifics of the 1928 spelling reform and its reception by the general public in Ukraine and abroad. In general, it is argued that in the Soviet Union language was often used as a tool of political consolidation, and the power struggle between different visions of the future of the republics can be seen in debates and reforms of language. Hence, the correlation between Soviet language policies and the subsequent Sovietisation (or Russification) is highlighted. The subsequent debates around the status of the Ukrainian language, its orthography and vocabulary exposed the unbridgeable differences between the political elites in the republic and powers in Moscow. The draft of the new orthography was thoroughly discussed by academics and linguists, representing different parts of Ukraine and the final draft was publicly discussed republic-wide. The spelling reform, adopted in 1929, can rightly be regarded as one of the greatest achievements of Ukrainizacija. This newly-acquired status was significantly challenged by the centralisation drive of the Moscow party leadership. This orthography, widely known as ’skrypnykivka’ (after the then Commissar for Education Mykola Skrypnyk) or ’Charkiv orthography’ was attacked for its attempts to dissociate the Ukrainian language from Russian and ’westernise’ the language. After 1933, the main principles of the spelling reform were labelled ’nationalistic’. The reform was quickly abandoned. Furthermore, after 1937, all the corpus planning attempts were geared towards ’purifying’ the Ukrainian language from foreign influence, when Russian equivalents and cognates were introduced or prioritised. © 2017 Author(s).

    Quadruple Helix Co-creation in SSH: Experiences, Considerations, Lessons Learned2017Rapport (Annet vitenskapelig)
    Abstract [en]

    Europe 2020, the European Union’s ten-year growth strategy, aims at delivering smart, sustainable and inclusive growth. The strategy sets targets in the areas of employment, research and development, climate change, education and poverty, and social exclusion for the coming decade. It is within this context that the Horizon 2020 scheme highlights impact, co-creation, and quadruple helix cooperation vehicles for innovation and in response to societal challenges. It is also here that the knowledge and research results of the social sciences and humanities (SSH) play a crucial role. At the same time, definitions and understanding of such concepts are ambiguous if not even contradictory, which makes it difficult to determine their applicability and effectiveness. This being said, there is a need for clearer definitions and viable and measurable valorisation processes to determine the value and outcomes of such processes. By the same token, there is a need to move beyond concepts and models into the actual work with these matters: to talk to the people from academia, government, industry and societal partners about their experiences with co-creation and the considerations these experiences have involved and the lessons that have been learned. To move beyond traditional and linear valorisation approaches (i.e. from academia to society), it is frequently claimed that quadruple helix actors need to be committed to and actively engaged in co-creation. Yet, due to its being boundary transgressive, co-creation is multifaceted and seldom naturally occurring. Also, collaboration and co-creation are often obstructed by differences in organisational culture, organisational logics and ideological disagreement among the actors involved. For all the reasons above, the ACCOMPLISSH consortium, made up of 14 universities from 12 countries (representing a range of SSH sub-disciplines), is engaged with a variety of quadruple helix partners from government, industry and society.

    Robotized Production Methods for Special Electric Machines2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    A research project on renewable energy conversion from ocean waves to electricity was started at the Division of Electricity at Uppsala University (UU) in 2001. The Wave Energy Converter (WEC) unit developed in this project is intended to be used in large offshore WEC farms and has therefore been designed with large-scale production in mind. The concept has now also been commercialized by the spin-off company Seabased Industry AB.

    An essential part of the UU WEC is the linear direct-drive generator. This thesis presents the pilot work on developing robotized production methods for this special electric machine. The generator design is here investigated and four different backbreaking, monotone, potentially hazardous and time consuming manual production tasks are selected for automation. A robot cell with special automation equipment is then developed and constructed for each task. Simplicity, reliability and flexibility are prioritized and older model pre-owned industrial robots are used throughout the work. The robot cells are evaluated both analytically and experimentally, with focus on full scale experiments. It is likely that the developed production methods can be applied also for other similar electric machines.

    The main focus in the thesis is on robotized stator cable winding. The here presented robot cell is, to the knowledge of the author, the first fully automated stator cable winding setup. Fully automated winding with high and consistent quality and high flexibility is demonstrated. Significant potential cost savings compared to manual winding are also indicated. The robot cell is well prepared for production, but further work is required to improve its reliability.

    The other three developed robot cells are used for stator stacking, surface mounting of permanent magnets on translators and machining of rubber discs. All robot cell concepts are experimentally validated and considerable potential cost savings compared to manual production are indicated. Further work is however required with regards to autonomy and reliability.

    Finally, the thesis presents a pedagogical development work connected to the research on robotized production methods. A first cycle course on automation and robot engineering is here completely reworked, as it is structured around three real-world group project tasks. The new course is evaluated from the examination results, the students’ course evaluations and the feedback from the teachers during six years. The students greatly appreciated the new course. It is indicated that the developed teaching approach is effective in teaching both classical and modern engineering skills.

    Local small business development in two Swedish northern rural areas: A matter of synergy, social capital and trust?2017Inngår i: Journal of Rural and Community Development, ISSN 1712-8277, E-ISSN 1712-8277, Vol. 12, nr 2/3, 143-167 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This exploratory paper examines the synergy between small businesses and the municipality in rural areas in northern Sweden, by exploring whether the degree of social capital and trust influences local small business development. Previous research shows that municipal policy tools, initiatives, and state-society synergy are crucial for local small business development in rural areas. This study challenge popular assumptions about how state-society synergy is imperative for local small business development by saying that a lack of vertical trust has in fact encouraged the entrepreneurial force and increased small business development in the rural areas studied. A qualitative case-study method was used including interviews, observations and studying of documents. Results show, by using the indicator ‘extent of trust in the municipality’ as measurement, that when there is strong horizontal social capital, it may in fact inhibit the possibility of creating strong vertical social capital, and the extent of trust towards the municipality is insignificant in promoting small business development in a rural area if the horizontal social capital is strong.

  • Naturvårdsplan för Sverige: En strategi för säkerställandearbetet1991Rapport (Annet vitenskapelig)
    Abstract [sv]

    Varför skall vi skydda värdefull natur? Behövs verkligen fler naturreservat och nationalparker? I så fall för vem och varför?

     

    Naturvårdsplan för Sverige beskriver de insatser som krävs även i framtiden för att skydda värdefull natur. Ett skydd och en vård som bör ske med utgångspunkt både från samhällets behov och med målet att bevara naturens mångfald och rikedom.

     

    Syftet med säkerställandearbetet är att med stöd av naturvårdslagen ge ett visst område eller naturvårdsobjekt ett rättsligt bindande skydd.

     

    Boken vänder sig till politiker, tjänstemän inom stat och kommun, organisationer, föreningar och till människor med intresse för natur och naturvård.

  • NATURVÅRD I FJÄLLEN1986Rapport (Annet vitenskapelig)
    Abstract [sv]

    År 1909 inrättade riksdagen ett antal nationalparker i Sverige, bl a 5 st i fjällregionen- Abisko, Stora Sjöfallet,Sarek, Pieljekaise och Sonfjället. Kunskapen om naturvärdena var då måhända med dagens mått inte den bästa men idag framstår besluten om nationalparkerna ändå som framsynta.

     

    Vi har nu en väsentligt bättre överblick av naturvärdena i fjällen. Genom bland annat insatser från naturgeografiska institutionen vid Stockholms Universitet har fjällens vegetation och geomorfologi kartlagts och genom särskilda inventeringar har faunan och urskogarna dokumenterats. Vi har idag fått en sådan kunskap om naturvärdena i fjällen att vi ganska väl kan avgöra vad som är särskilt värdefullt och behöver skyddas.

     

    I denna publikation redovisar naturvårdsverket emellertid bara hur inventeringarna genomförts och vilka områden i fjällen som är mest värdefulla. Därtill förs en diskussion om tänkbara ambitionsnivåer för skydd av fjällen och synpunkter på hur de skall skyddas. Vi hoppas att "Naturvård i fjällen" skall sätta fart på debatten om hur och hur mycket av fjällen som skall skyddas. Därefter kommer naturvårdsverket att i särskild ordning framlägga ett förslag till naturvårdsplan för fjällen, för att ge riksdagen svar på frågan om "de svenska fjällområdenas planmässiga användning inom ramen för modern naturvård".

     

    Trots att vi redan har ett hyggligt skydd av stora delar av vår fantastiska fjällvärld som nationalparker, naturreservat eller obrutna fjäll kan vi behöva skydda ännu flera områden. I ett vidare sammanhang är fjällen "Europas sista stora vildmark", vilken Sverige måste akta noga så att den även i framtiden förblir en tillgång för oss alla.

    Creating an ability to respond to changing requirements by systematic modelling of design assets and processes2017Konferansepaper (Fagfellevurdert)
    Abstract [en]

    System suppliers, e.g. original equipment suppliers, are important for the success of many products. They design a unique solution, often in close collaboration with other companies, based on different product concepts and/or core technologies. The solution can then be manufactured in different quantities depending on the client’s need. High level of customization is required as the interfaces are not standardized, the performance is not negotiable, requirements are not initially fixed and the specific system interacts with, is affected by, or affects other systems that are simultaneously developed. A system supplier commonly designs and manufactures solutions for different OEMs and must support many models and variants in their product portfolios. Efficiency, short lead-time, continuous technology development, and adaptability are essential for the competitive edge. A product platform approach has been a success for many companies to enable variety at low cost, however, it is not applicable for system suppliers. This work describes the result from a case study where a platform approach enabling a new way of structuring, publishing and managing design assets and processes was introduced at a company with the purpose to improve the ability to respond to changing requirements in the quotation process and the subsequent product development activities.

    Psychometric validation of the Persian bergen social media addiction scale using classic test theory and Rasch models2017Inngår i: Journal of Behavioral Addictions, ISSN 2062-5871, E-ISSN 2063-5303, Vol. 6, nr 4, 620-629 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background and aims: The Bergen Social Media Addiction Scale (BSMAS), a six-item self-report scale that is a brief and effective psychometric instrument for assessing at-risk social media addiction on the Internet. However, its psychometric properties in Persian have never been examined and no studies have applied Rasch analysis for the psychometric testing. This study aimed to verify the construct validity of the Persian BSMAS using confirmatory factor analysis (CFA) and Rasch models among 2,676 Iranian adolescents.

    Methods: In addition to construct validity, measurement invariance in CFA and differential item functioning (DIF) in Rasch analysis across gender were tested for in the Persian BSMAS.

    Results: Both CFA [comparative fit index (CFI) = 0.993; Tucker-Lewis index (TLI) = 0.989; root mean square error of approximation (RMSEA) = 0.057; standardized root mean square residual (SRMR) = 0.039] and Rasch (infit MnSq = 0.88-1.28; outfit MnSq = 0.86-1.22) confirmed the unidimensionality of the BSMAS. Moreover, measurement invariance was supported in multigroup CFA including metric invariance (ΔCFI = .0.001; ΔSRMR = 0.003; ΔRMSEA = .0.005) and scalar invariance (ΔCFI = .0.002; ΔSRMR = 0.005; ΔRMSEA = 0.001) across gender. No item displayed DIF (DIF contrast = .0.48 to 0.24) in Rasch across gender.

    Conclusions: Given the Persian BSMAS was unidimensional, it is concluded that the instrument can be used to assess how an adolescent is addicted to social media on the Internet. Moreover, users of the instrument may comfortably compare the sum scores of the BSMAS across gender.

    Climate Change, Dengue and Aedes Mosquitoes: Past Trends and Future Scenarios2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Background Climate change, global travel and trade have facilitated the spread of Aedes mosquitoes and have consequently enabled the diseases they transmit (dengue fever, Chikungunya, Zika and yellow fever) to emerge and re-emerge in uninfected areas. Large dengue outbreaks occurred in Athens in 1927 and in Portuguese island, Madeira in 2012, but there are almost no recent reports of Aedes aegypti, the principal vector, in Europe. A dengue outbreak needs four conditions: sufficient susceptible humans, abundant Aedes vector, dengue virus introduction, and conducive climate. Can Aedes aegypti establish themselves again in Europe in the near future if they are introduced? How do the current and future climate affect dengue transmission globally, and regionally as in Europe? This thesis tries to answer these questions.

    Methods Two process-based mathematical models were developed in this thesis. Model 1 describes a vector’s ability to transmit dengue – vectorial capacity – based on temperature and diurnal temperature range (DTR). Model 2 describes vector population dynamics based on the lifecycle of Aedes aegypti. From this model, vector abundance was estimated using both climate as a single driver, and climate together with human population and GDP as multiple drivers; vector population growth rate was derived as a threshold condition to estimate the vector’s invasion to a new place.

    Results Using vectorial capacity, we estimate dengue epidemic potential globally for Aedes aegypti and in Europe for Aedes aegypti and Aedes albopictus. We show that mean temperature and DTR are both important in modelling dengue transmission, especially in a temperate climate zone like Europe. Currently, South Europe is over the threshold for dengue epidemics if sufficient dengue vectors are present. Aedes aegypti is on the borderline of invasion into the southern tip of Europe. However, by end of this century, the invasion of Aedes aegypti may reach as far north as the middle of Europe under the business-as-usual climate scenario. Or it may be restricted to the south Europe from the middle of the century if the low carbon emission – Paris Agreement – is implemented to limit global warming to below 2°C.

    Conclusion Climate change will increase the area and time window for Aedes aegypti’s invasion and consequently the dengue epidemic potential globally, and in Europe in particular. Successfully achieving the Paris Agreement would considerably change the future risk scenario of a highly competent vector – Aedes aegypti’s – invasion into Europe. Therefore, the risk of transmission of dengue and other infectious diseases to the mainland of Europe depends largely on human efforts to mitigate climate change.

    Ulleråker – kulturarv, genus och funktionsnormer2017Inngår i: Nordisk Museologi, ISSN 1103-8152, nr 2, 142-147 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper provides a presentation of the project Ulleråker – funktionsnedsättning och kulturarv funded by the National Heritage Board. The project seeks to investigate the transformation of Ulleråker, a former psychiatric hospital in the outskirts of Uppsala (Sweden). The project will study how cultural heritage is transformed, and formed, during urban development and rebuilding processes, with a particular focus on gender and functionality norms. The project examines different kinds of material in order to illuminate how cultural heritage is articulated and materialized in the area. The material is analyzed using a composite theory of critical heritage studies coupled with crip and gender studies. The purpose of the project is to contribute to develop methods and theories in how to deal with the cultural heritage of psychiatric hospitals during times of transformation.

    From biopiracy to bioprospecting: Negotiating the Limits of Propertization2017Inngår i: Property, Place and Piracy / [ed] James Arvanitakis and Martin Fredriksson, Routledge, 2017, 174-186 s.Kapittel i bok, del av antologi (Fagfellevurdert)
    Abstract [en]

    Since the 1990s the patenting a n d commodification of biological resources and traditional knowledge has become a contested phenomenon. This practice comes in many guises: it can be conducted by universities working in collaboration with local communities, by small commercial research companies or by multinational pharmaceutical corporations. Some call it biopiracy while others prefer the term bioprospecting or biodiscovery. The choice of words is significant as it reflects not only different ways to conduct and distribute the revenues from patenting of biological resources, but also different ways to look at the legitimacy of biopatents as such. This chapter takes the Nagoya Protocol – a UN protocol aiming to prevent biopiracy – as an example to discuss how the negotiations over bio patents also reflect different approaches to commodification of nature and the limits of propertization.

    Abstract [en]

    High accuracy of impact height is important to get reliableRadio Occultation (RO) measurements of the atmosphere refractivity.We have made an investigation on how accuratelywe can measure the impact height at ground level using waveoptics simulations, realistic refractivity profiles, a realisticsimulator for an advanced RO instrument including noise,and using phase matching for the inversion. The idea of theinvestigation is to increase the measurement accuracy of impactheight at low altitudes and to give reliable measurementseven in cases of super-refractive layers. We present statisticson the accuracy and precision of the determination of theimpact height at ground, as well as the resulting accuracy andprecision in the measured refractivity.

    Kriterier för biologisk värdering av natur från skyddssynpunkt1984Rapport (Annet vitenskapelig)
    Abstract [sv]

    Rapporten behandlar naturvärdesbedömningens roll i naturvården och ger en översikt över kriterier som använts för värdering av natur. Kriterierna diversitet, yta, raritet, naturlighet och representativitet diskuteras utförligt, både med avseende på definitioner, mätmetoder och värderingar.

     

    I en arbetsmodell föreslås naturvårdsvärdet kombineras av (1) en ekologisk värdering, (2) en värdering av representationen, dvs huruvida de karaktärer som ett område företräder finns representerade i regionens reservat, (3) en värdering av skyddets effektivitet, (4) en 'politisk' värdering av ekosystemkaraktärerna. Rapporten avslutas med en diskussion av möjligheterna att sammanväga olika värden.

    Positive selection on human gamete-recognition genes2018Inngår i: PeerJ, ISSN 2167-8359, E-ISSN 2167-8359, Vol. 6, e4259Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Coevolution of genes that encode interacting proteins expressed on the surfaces of sperm and eggs can lead to variation in reproductive compatibility between mates and reproductive isolation between members of different species. Previous studies in mice and other mammals have focused in particular on evidence for positive or diversifying selection that shapes the evolution of genes that encode sperm-binding proteins expressed in the egg coat or zona pellucida (ZP). By fitting phylogenetic models of codon evolution to data from the 1000 Genomes Project, we identified candidate sites evolving under diversifying selection in the human genes ZP3 and ZP2. We also identified one candidate site under positive selection in C4BPA, which encodes a repetitive protein similar to the mouse protein ZP3R that is expressed in the sperm head and binds to the ZP at fertilization. Results from several additional analyses that applied population genetic models to the same data were consistent with the hypothesis of selection on those candidate sites leading to coevolution of sperm- and egg-expressed genes. By contrast, we found no candidate sites under selection in a fourth gene (ZP1) that encodes an egg coat structural protein not directly involved in sperm binding. Finally, we found that two of the candidate sites (in C4BPA and ZP2) were correlated with variation in family size and birth rate among Hutterite couples, and those two candidate sites were also in linkage disequilibrium in the same Hutterite study population. All of these lines of evidence are consistent with predictions from a previously proposed hypothesis of balancing selection on epistatic interactions between C4BPA and ZP3 at fertilization that lead to the evolution of co-adapted allele pairs. Such patterns also suggest specific molecular traits that may be associated with both natural reproductive variation and clinical infertility.

    Pushing the limits of neutron tomography in palaeontology: Three-dimensional modelling of in situ resin within fossil plants2017Inngår i: Palaeontologia Electronica, ISSN 1935-3952, E-ISSN 1094-8074, Vol. 20, nr 3, 1-12 s., 20.3.57AArtikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Computed tomography is an increasingly popular technique for the non-destructivestudy of fossils. Whilst the science of X-ray computed tomography (CT) has greatlymatured since its first fossil applications in the early 1980s, the applications and limitationsof neutron tomography (NT) remain relatively unexplored in palaeontology. Thesehighest resolution neutron tomographic scans in palaeontology to date were conductedon a specimen of Austrosequoia novae-zeelandiae (Ettingshausen) Mays and Cantrillrecovered from mid-Cretaceous (Cenomanian; ~100–94 Ma) strata of the ChathamIslands, eastern Zealandia. Previously, the species has been identified with in situ fossilresin (amber); the new neutron tomographic analyses demonstrated an anomalouslyhigh neutron attenuation signal for fossil resin. The resulting data provided astrong contrast between, and distinct three-dimensional representations of the: 1) fossilresin; 2) coalified plant matter; and 3) sedimentary matrix. These data facilitated ananatomical model of endogenous resin bodies within the cone axis and bract-scalecomplexes. The types and distributions of resin bodies support a close alliance withSequoia Endlicher (Cupressaceae), a group of conifers whose extant members areonly found in the Northern Hemisphere. This study demonstrates the feasibility of NTas a means to differentiate chemically distinct organic compounds within fossils.Herein, we make specific recommendations regarding: 1) the suitability of fossil preservationstyles for NT; 2) the conservation of organic specimens with hydrogenous consolidantsand adhesives; and 3) the application of emerging methods (e.g., neutronphase contrast) for further improvements when imaging fine-detailed anatomical structures.These findings demonstrate that we are still far from reaching the conceptuallimits of NT as a means of virtually extracting fossils, or imaging their internal anatomyeven when embedded within a rock matrix.

    Geomorf ologisk kartläggning för naturvärdesbedömning och planering: En flygbildsmetodisk studie i syd- och mellansvensk terräng1980Rapport (Annet vitenskapelig)
    Abstract [sv]

    Under 1970-talet har inte minst från SNV:s forskningsnämnds sida betydande satsningar gjorts för att finna metoder att förbättra underlaget för den fysiska planeringen genom heltäckande naturresursinventeringar och naturvärdesbedömningar. Den Naturgeografiska institutionen vid Stockholms universitet har främst medverkat genom att utveckla inventeringsmetodik baserad på flygbildsteknik för geomorfologiska kartläggning och översiktlig vegetationskartering.

    Professor Gunnar Hoppe initierade 1969 metodstudier avseende geomorfologisk kartering av fjällkedjan i skala 1:250 000. Det första resultatet, angivet som provisoriskt, förelåg två år senare i form av en geomorfologisk karta över nordvästra Dalarna framtagen av Dieter Soyez. Metodstudierna följdes efter fortsatt utvecklingsarbete av en tillämpad kartläggning av hela den svenska fjällkedjan under Gunnar Hoppes ledning och på uppdrag av Naturvårdsverket. Projektet, som nu står inför sin fullbordan, omfattar kartblad med beskrivningar och naturvärdesbedömningar.

    Polar wildfires and conifer serotiny during the Cretaceous globalhothouse2017Inngår i: Geology, ISSN 0091-7613, E-ISSN 1943-2682, Vol. 45, nr 12, 1119-1122 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Several highly effective fire-adaptive traits first evolved among modern plants duringthe mid-Cretaceous, in response to the widespread wildfires promoted by anomalously highatmospheric oxygen (O2) and extreme temperatures. Serotiny, or long-term canopy seedstorage, is a fire-adaptive strategy common among plants living in fire-prone areas today,but evidence of this strategy has been lacking from the fossil record. Deposits of abundantfossil charcoal from sedimentary successions of the Chatham Islands, New Zealand, recordwildfires in the south polar regions (75°–80°S) during the mid-Cretaceous (ca. 99–90 Ma).Newly discovered fossil conifer reproductive structures were consistently associated withthese charcoal-rich deposits. The morphology and internal anatomy as revealed by neutrontomography exhibit a range of serotiny-associated characters. Numerous related fossils fromsimilar, contemporaneous deposits of the Northern Hemisphere suggest that serotiny was akey adaptive strategy during the high-fire world of the Cretaceous.

    On Service Innovation and Realization in Manufacturing Firms2015Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Service innovation is increasingly becoming a basis for manufacturing firms to reach and sustain competitive advantages. While traditional product innovation typically includes how new technology can be utilized in new products, service innovation spans a broader area that is not exclusively focused on new technology, but rather how resources can be developed into value propositions and then integrated in the customer’s process in order to support customer value creation through realization. However, manufacturing firms that infuse services struggle with service innovation; this becomes especially evident in the realization phase.

    This thesis is a compilation of five papers discussing different aspects of service innovation realization and the inherited challenges. The study builds upon empirical data from four Swedish manufacturing firms that infuse services and develop new value propositions that include both products and services to support customer processes.

    The thesis illustrates realization as a phase in service innovation where the firm interacts with its customer in order to adjust, revise and further find new ways of improving the customer’s processes through for example customer training. Realization is characterized by a deployment phase and a post-deployment phase that represent the ongoing relationship between the customer and the firm.

    Depending on who has the competencies or ability to integrate the resources that are needed for service innovation, different interaction patterns are identified. Through indirect interaction, the firm facilitates the customer’s value creation through, for example, preventive maintenance, while through direct interaction the firm acts as a co-creator in the service innovation process and hence work jointly together with the customer in order to improve customer value creation.

    This thesis contributes to the literature by characterizing service innovation realization and by increasing the understanding for different interaction patterns in the service innovation process.

    Öbiogeografisk teori och bildning av naturreservat1982Rapport (Annet vitenskapelig)
    Abstract [sv]

    Naturreservat kan betraktas som ekologiska öar i en alltmer påverkad omgivning och därmed bedömas utifrån öbiogeografisk teori. Innebörden av denna teori, som beskriver bl a sambandet mellan ö-storlek och artantal med utgångspunkt från invandrings- resp. utdöendehastigheter presenteras i föreliggande rapport, liksom den debatt som uppstått kring teorin. Analyser demonstrerar ö-teorins giltighet för o lika organismgrupper (fiskar, skalbaggar, kärlväxter) i Sverige. De teoretiska konsekvenserna av förändringar av reservat ytor för antalet fågelarter diskuteras, samt den konflikt som råder mellan intressen företrädande dag ens produktionslandskap och ur ö-teoretisk synvinkel önskvärd reservatavsättning. Det aktuella antalet svenska reservat och deras yta, storleksfördelning, former och lokalisering är f n i ringa samstämmighet med ö-teorin. För att i framtiden ha kvar ett så varierat växt- och djurliv som möjligt måste de n totala reservat ytan öka. Man bör avsätta fler större reservat än små, och minska avstånden till andra reservat genom att skapa nya småreservat eller biotopkorridorer. Reservat bör ha så liten omkrets i förhållande till yta som möjligt och vidare, ej nödvändigtvis vara anpassade till aktuella ägogränser.

    Abstract [sv]

    Projektets målsättning är att klarlätgga möjligheterna att med hjälp av flygbilder, framför allt IR- färgbilder, kartlägga vegetation i skärgårdsområden. genom jämförelser av tolkningar med fältdata särskiljs tolkningsmöjligheterna i olika bildmaterial. Fyra olika bildmaterial, varav två IRfärg, har prövats.

    För kartering på översiktlig nivå kan IR-färgfilm i skala 1:50 000 utnyttjas om bilderna tolkas i goda tolkningsinstrument. För kartering på detaljerad nivå bör bildskalan ökas till 1:20 000. Hedovisning av kartering från flygbilder kan göras i form av vegetationskartor. På översiktlig nivå bör kartskalan ej vara mindre än 1:30 000. I annat fall går landskapets karaktär förlorad . På detaljerad nivå bör redovisningsskalan ej understiga 1:15 000.

    Sample efficient optimization for learning controllers for bipedal locomotion2016Inngår i: IEEE-RAS 16th International Conference on Humanoid Robots (Humanoids), 2016, IEEE conference proceedings, 2016Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Learning policies for bipedal locomotion can be difficult, as experiments are expensive and simulation does not usually transfer well to hardware. To counter this, we need algorithms that are sample efficient and inherently safe. Bayesian Optimization is a powerful sample-efficient tool for optimizing non-convex black-box functions. However, its performance can degrade in higher dimensions. We develop a distance metric for bipedal locomotion that enhances the sample-efficiency of Bayesian Optimization and use it to train a 16 dimensional neuromuscular model for planar walking. This distance metric reflects some basic gait features of healthy walking and helps us quickly eliminate a majority of unstable controllers. With our approach we can learn policies for walking in less than 100 trials for a range of challenging settings. In simulation, we show results on two different costs and on various terrains including rough ground and ramps, sloping upwards and downwards. We also perturb our models with unknown inertial disturbances analogous with differences between simulation and hardware. These results are promising, as they indicate that this method can potentially be used to learn control policies on hardware.

    Detection of Residents' Abnormal Behaviour by Analysing Energy Consumption of Individual Households2017Inngår i: Proceedings of the 17th IEEE International Conference on Data Mining Workshops (ICDMW), IEEE, 2017, 729-738 s.Konferansepaper (Fagfellevurdert)
    Abstract [en]

    As average life expectancy continuously rises, assisting the elderly population with living independently is of great importance. Detecting abnormal behaviour of the elderly living at home is one way to assist the eldercare systems with the increase of the elderly population. In this study, we perform an initial investigation to identify abnormal behaviour of household residents using energy consumption data. We conduct an experiment in two parts, the first to identify a suitable prediction algorithm to model energy consumption behaviour, and the second to detect abnormal behaviour. This approach allows for an initial step for the elderly care that has a low cost, is easily deployable, and is non-intrusive.

    Hållbara turistresor: En fallstudie av destinationerna Kiruna, Åre, Sälen och Vimmerby2017Rapport (Annet vitenskapelig)
    Abstract [sv]

    I samband med vidareutveckling av destinationer och transportsystem är turisternas önskemål ochbehov avgörande för vilka åtgärder och förändringar som kan leda till ett mer hållbart resande.Resmöjligheterna för resan till och från destinationer har stor betydelse, men även tillgängligheten, imeningen geografisk tillgänglighet, till olika besökspunkter inom destinationer. God tillgänglighetutan egen bil inom destinationen kan även påverka färdmedelsvalet för resan till och fråndestinationen.Syftet med den studie som avrapporteras här är att analysera olika kategorier av turisters resbehov,resmönster och önskemål avseende resandet till och från samt inom fyra utvalda svenska destinationer:Kiruna, Åre, Sälen och Vimmerby. Avsikten är att fördjupa kunskaperna om faktorer som kan ha eninverkan på möjligheterna att öka turistresors hållbarhet. Det empiriska material som ligger till grundför analysen är inhämtat genom enkäter till besökare på plats i destinationerna.Rapporten visar att turismen ser olika ut och har olika ekonomisk potential för olika destinationer. Detfinns stora skillnader mellan såväl resmönster (färdmedelsval) som ekonomisk effekt (mätt somgästnattskonsumtion) mellan olika kategorier av turister, olika typer av destinationer och mellan olikasäsonger.En central generell slutsats från studien är att turisterna önskar tillgänglighet till många olika besökspunkterinom destinationerna. Destinationens utformning eller fysiska struktur, det vill säga lokaliseringenav boende och besökspunkter, har alltså stor betydelse för tillgängligheten och resbehovetinom destinationen. Både destinationens fysiska struktur och tillgången till olika alternativa färdmedelär därmed viktiga för möjligheterna att öka turistresandets hållbarhet. Det innebär att god kännedomom den geografiska tillgängligheten för turister behövs för planering och utveckling av hållbaradestinationer och turistresor, liksom god kännedom om turisternas beteende och önskemål.

    Resource Allocation for Max-Min Fairness in Multi-Cell Massive MIMO2017Licentiatavhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Massive MIMO (multiple-input multiple-output) is considered as an heir of the multi-user MIMO technology and it has recently gained lots of attention from both academia and industry. By equipping base stations (BSs) with hundreds of antennas, this new technology can provide very large multiplexing gains by serving many users on the same time-frequency resources and thereby bring significant improvements in spectral efficiency (SE) and energy efficiency (EE) over the current wireless networks. The transmit power, pilot training, and spatial transmission resources need to be allocated properly to the users to achieve the highest possible performance. This is called resource allocation and can be formulated as design utility optimization problems. If the resource allocation in Massive MIMO is optimized, the technology can handle the exponential growth in both wireless data traffic and number of wireless devices, which cannot be done by the current cellular network technology.

    In this thesis, we focus on two resource allocation aspects in Massive MIMO: The first part of the thesis studies if power control and advanced coordinated multipoint (CoMP) techniques are able to bring substantial gains to multi-cell Massive MIMO systems compared to the systems without using CoMP. More specifically, we consider a network topology with no cell boundary where the BSs can collaborate to serve the users in the considered coverage area. We focus on a downlink (DL) scenario in which each BS transmits different data signals to each user. This scenario does not require phase synchronization between BSs and therefore has the same backhaul requirements as conventional Massive MIMO systems, where each user is preassigned to only one BS. The scenario where all BSs are phase synchronized to send the same data is also included for comparison. We solve a total transmit power minimization problem in order to observe how much power Massive MIMO BSs consume to provide the requested quality of service (QoS) of each user. A max-min fairness optimization is also solved to provide every user with the same maximum QoS regardless of the propagation conditions.

    The second part of the thesis considers a joint pilot design and uplink (UL) power control problem in multi-cell Massive MIMO. The main motivation for this work is that the pilot assignment and pilot power allocation is momentous in Massive MIMO since the BSs are supposed to construct linear detection and precoding vectors from the channel estimates. Pilot contamination between pilot-sharing users leads to more interference during data transmission. The pilot design is more difficult if the pilot signals are reused frequently in space, as in Massive MIMO, which leads to greater pilot contamination effects. Related works have only studied either the pilot assignment or the pilot power control, but not the joint optimization. Furthermore, the pilot assignment is usually formulated as a combinatorial problem leading to prohibitive computational complexity. Therefore, in the second part of this thesis, a new pilot design is proposed to overcome such challenges by treating the pilot signals as continuous optimization variables. We use those pilot signals to solve different max-min fairness optimization problems with either ideal hardware or hardware impairments.

    Thyasirid bivalves from Cretaceous and Paleogene cold seeps2017Inngår i: Acta Palaeontologica Polonica, ISSN 0567-7920, E-ISSN 1732-2421, Vol. 62, nr 4, 705-728 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We present a systematic study of thyasirid bivalves from Cretaceous to Oligocene seep carbonates worldwide. Eleven species of thyasirid bivalves are identified belonging to three genera: Conchocele, Maorithyas, and Thyasira. Two species are new: Maorithyas humptulipsensis sp. nov. from middle Eocene seep carbonates in the Humptulips Formation, Washington State, USA, and Conchocele kiritachiensis sp. nov. from the late Eocene seep deposit at Kiritachi, Hokkaido, Japan. Two new combinations are provided: Conchocele townsendi (White, 1890) from Maastrichtian strata of the James Ross Basin, Antarctica, and Maorithyas folgeri (Wagner and Schilling, 1923) from Oligocene rocks from California, USA. Three species are left in open nomenclature. We show that thyasirids have Mesozoic origins and appear at seeps before appearing in “normal” marine environments. These data are interpreted as a record of seep origination of thyasirids, and their subsequent dispersal to non-seep environments. We discuss the age of origination of thyasirids in the context of the origin of the modern deep sea fauna and conclude that thyasirids could have deep sea origins. This hypothesis is supported by the observed lack of influence of the Cretaceous and Paleogene Oceanic Anoxic Events on the main evolutionary lineages of the thyasirids, as seen in several other members of the deep sea fauna.

    Abstract [en]

    The recent developments and adoptions of digital technologies give rise to the growth of information economies, understood as an aggregate of economic activities that produce informational outputs. Several key characteristics of an information economy differ to the conventional economic wisdom derived from the industrial age, which may impose governmental policy implications and therefore constitutes a key question: how to govern the newly emerged information economy with the thinking of the industrial age economy. Resolving this problem requires, among others, comprehensive understanding of information economies. To that end, Sweden is among the most advanced adopters of digital technologies and represents therefore a suitable empirical base for the investigation of an information economy. This paper offers preliminary results from a first ever account of the Swedish information economy in terms of its value created, jobs and wages; this account shows that the Swedish economy is dominated by its information economy, which requires a careful attention of policy makers.

    The Swedish Information Economy: Current Evidence and Key Government Policy Implications2017Inngår i: Proceedings of the 8th International Conference on Society and Information Technologies (ICSIT 2017), Orlando, USA, 2017, 23-28 s.Konferansepaper (Fagfellevurdert)
    Abstract [en]

    It is well known that most of the largest economies in the world are becoming information economies (understood as an aggregate of economic activities that produce information outputs) in terms of value added (GNP) and jobs. Sweden is among the most advanced adopters of ICT and represents therefore a suitable empirical base for the investigation of an information economy. The data reveal that the largest part of the Swedish economy in terms of GNP value added is constituted by information services. This study presents some surprising economic structures never before uncovered, which are discussed here and then contextualized in terms of implications for public policy making.

    Smileys Without Borders: A Critique of Transboundary Interaction Between Politicians, Journalists and PR practitioners on Social Media2018Inngår i: TripleC: Communication, Capitalism & Critique, E-ISSN 1726-670X, Vol. 16, nr 1Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The purpose of this article is to contribute a critical theoretical understanding of cross-professional relations on social media, focusing on politicians, journalists and PR practitioners. It is well known that these professional groups establish personal and close relations in offline contexts, but more attention needs to be paid to the role of social media. Here, it is argued that in the context of digital media use, semi-private chatting, humour, and mutual acknowledgment, including the use of likes, smileys, heart symbols, etc., are evidence of a ‘neoliberalisation’ of cross-professional relations. The underlying idea is that the common practice of self-branding undermines representations of professional belonging and exacerbates the blurring of professional boundaries. The critical conceptualisation of such ‘transboundary’ interaction between politicians, journalists and PR practitioners, which is guided by a culturalmaterialist approach, includes the presentation of examples deriving from the Swedish Twittersphere, and suggestions for empirical research.

    Software Programmer Productivity: A Complementary-Based Research Model2017Inngår i: Proceedings of the 25th European Conference on Information Systems, Guimarães, Portugal, 2017, 2755-2766 s.Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The identification of the factors that condition a software programmer’s productivity remains a key challenge for both scholars and practitioners. While a number of studies have focused on the impact of one or a few particular factors, the way these factors jointly condition programmer productivity is still unknown. This paper presents a conceptual model aimed at a comprehensive understanding of the factors that complement each other to govern the productivity of a software programmer. The model is based on complementarity theory and its systems approach and addresses an individual worker’s productivity, which accounts for cognitive, technological, and organizational characteristics. The analyzed factors are organized into a system of complementarities, offering two propositions that specify the conditions of a programmer’s productivity. The model’s key contribution lies in its unique configuration of two systems of complementarities, which have the potential to add to the literature on the productivity of software programmers. The proposed model can be employed as a guidance for the design of empirical investigations of the conditions of individual software programmers’ productivity as well as information worker productivity in general.
