    Interview With Claude Romano2017In: HORIZON-FENOMENOLOGICHESKIE ISSLEDOVANIYA, ISSN 2226-5260, Vol. 6, no 1, p. 241-264Article in journal (Other academic)
    Abstract [en]

    What is the event? How the phenomenology of event is possible if the "event" is not the phenomenon in the classical meaning of this word? French philosopher Claude Romano discusses these questions with his Russian colleague Ruslan Loshakov. The interlocutors consider the concept of event in different contexts, paying special attention to the relationships which connect the phenomenology of event with Husserl, Bergson, Heidegger and Levinas' ideas.

    High-Order Numerical Simulations of Wind Turbine Wakes2017In: WAKE CONFERENCE 2017, IOP PUBLISHING LTD , 2017, article id 012025Conference paper (Refereed)
    Abstract [en]

    Previous attempts to describe the structure of wind turbine wakes and their mutual interaction were mostly limited to large-eddy and Reynolds-averaged Navier Stokes simulations using finite volume solvers. We employ the higher-order spectral-element code Nek5000 to study the influence of numerical aspects on the prediction of the wind turbine wake structure and the wake interaction between two turbines. The spectral-element method enables an accurate representation of the vortical structures, with lower numerical dissipation than the more commonly used finite-volume codes. The wind-turbine blades are modeled as body forces using the actuator-line method (ACL) in the incompressible Navier Stokes equations. Both tower and nacelle are represented with appropriate body forces. An inflow boundary condition is used which emulates homogeneous isotropic turbulence of wind-tunnel flows. We validate the implementation with results from experimental campaigns undertaken at the Norwegian University of Science and Technology (NTNU Blind Tests), investigate parametric influences and compare computational aspects with existing numerical simulations. In general the results show good agreement between the experiments and the numerical simulations both for a single turbine setup as well as a two-turbine setup where the turbines are offset in the spanwise direction. A shift in the wake center caused by the tower wake is detected similar to experiments. The additional velocity deficit caused by the tower agrees well with the experimental data. The wake is captured well by Nek5000 in comparison with experiments both for the single wind turbine and in the two-turbine setup. The blade loading however shows large discrepancies for the high-turbulence, two-turbine case. While the experiments predicted higher thrust for the downstream turbine than for the upstream turbine, the opposite case was observed in Nek5000.

    Advancing Models of Privacy Decision Making: Exploring the What & How of Privacy Behaviours2018Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    People's decisions do not happen in a vacuum; there are multiple factors that may affect them. There are external determinants, such as cost/benefit calculation of decision outcomes. There are also internal factors, such as attitudes, personality, emotions, age, and nationality. Frequently, the latter have a final say on the decision at hand, and similar determinants are triggered during the digital interaction when people make decisions about their privacy.

    The current digital privacy landscape is filled with recurring security breaches and leaks of personal information collected by online service providers. Growing dependency on Internet-connected devices and increasing privacy risks prompted policy makers to protect individuals' right to privacy. In Europe, the General Data Protection Regulation requires companies to provide adequate information about their data collection and processing practices to users, to increase privacy awareness and enable better decision making. Regardless, currently there is no sufficient, usable technology, which could help people make improved privacy decisions, decreasing over-disclosure and oversharing. Hence, multidisciplinary researchers aim at developing new privacy-enhancing solutions. To define such solutions and successfully convey data provision and processing practices, potential risks, or harms resulting from information disclosure, it is crucial to understand cognitive processes underpinning privacy decisions.

    In this thesis, we examine privacy decisions and define factors that influence them. We investigate the attitude-behaviour relationship and identify privacy concerns affecting perceptions of privacy. Additionally, we examine factors influencing information sharing, such as emotional arousal and personality traits. Our results demonstrate that there is a relationship between privacy concerns and behaviours, and that simplified models of behaviour are insufficient to predict privacy decisions. Our findings show that internal factors, such as nationality and culture, emotional arousal, and individual characteristics, affect privacy decisions. Based on our findings, we conclude that future models of privacy should incorporate such determinants. Further, we postulate that privacy user interfaces must become more flexible and personalised than the current solutions.

    Dissolved organic carbon in streams within a subarctic catchment analysed using a GIS/remote sensing approach2018In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 13, no 7, article id e0199608Article in journal (Refereed)
    Abstract [en]

    Climate change projections show that temperature and precipitation increases can alter the exchange of greenhouse gases between the atmosphere and high latitude landscapes, including their freshwaters. Dissolved organic carbon (DOC) plays an important role in greenhouse gas emissions, but the impact of catchment productivity on DOC release to subarctic waters remains poorly known, especially at regional scales. We test the hypothesis that increased terrestrial productivity, as indicated by the normalized difference vegetation index (NDVI), generates higher stream DOC concentrations in the Stordalen catchment in subarctic Sweden. Furthermore, we aimed to determine the degree to which other generic catchment properties (elevation, slope) explain DOC concentration, and whether or not land cover variables representing the local vegetation type (e.g., mire, forest) need to be included to obtain adequate predictive models for DOC delivered into rivers. We show that the land cover type, especially the proportion of mire, played a dominant role in the catchment's release of DOC, while NDVI, slope, and elevation were supporting predictor variables. The NDVI as a single predictor showed weak and inconsistent relationships to DOC concentrations in recipient waters, yet NDVI was a significant positive regulator of DOC in multiple regression models that included land cover variables. Our study illustrates that vegetation type exerts primary control in DOC regulation in Stordalen, while productivity (NDVI) is of secondary importance. Thus, predictive multiple linear regression models for DOC can be utilized combining these different types of explanatory variables.

    A Mind Body Skills Course Among Nursing and Medical Students: A Pathway for an Improved Perception of Self and the Surrounding World2018In: Global Qualitative Nursing Research, ISSN 2333-3936, Vol. 5Article in journal (Refereed)
    Abstract [en]

    Despite increased recognition of self-care and self-awareness as core competences for health care professionals, little attention is paid to these skills during their education. Evidence suggests that a Mind-Body (MB) skills course has the potential to enhance self-care and self-awareness among medical students. However, less is known about the meaning of this course for students and how it affects their personal and professional life. Therefore, we examined the lived experiences with an MB skills course among Dutch medical and Swedish nursing students. This course included various MB techniques, such as mindfulness meditation and guided imagery. Guided by a phenomenological hermeneutical method, three main themes were identified: "ability to be more present," "increased perception and awareness of self," and "connection on a deeper level with others." Overall, participation in the MB skills course served as a pathway to inner awareness and supported connecting with others as well as with the surrounding world.

    Enhanced Customer Cooperation: Experiences with cooperative compliance in Finland2018Report (Refereed)
    Abstract [en]

    This report examines the experiences with a collaborative compliance project – Enhanced Customer Cooperation (ECC) – introduced by the Finnish Tax Administration. The ECC was introduced by the Large Taxpayers’ Unit of the Finnish Tax Administration at the beginning of 2013, and it ran as a pilot until the end of 2015. Since the start of 2016, the ECC has been a part of the permanent operations of the Large Taxpayers’ Unit. Based on the interviews with tax officers, corporations participating in the ECC and tax lawyers and tax consultants, the ECC is bringing about a cultural change in the administrative practices and ways of communicating between tax authorities and taxpayers. In general, the ECC’s objective of increasing cooperation between tax administration and taxpayers has been welcomed. There were, however, some concerns about the impartiality towards taxpayers, efficiency in the use of human resources and the possible retrospective involvement of the Tax Recipients’ Legal Services Unit. In addition, because predictability was described as one of the key aspects of taxation for companies, many questions have been raised regarding whether the ECC can deliver more predictability in taxation practices.

    Arctic Risk in Urban Spaces (ARUS): Report of meeting 16th & 17th January 20182018Report (Other academic)
    Abstract [en]

    Report from the ARUS workshop in Abisko Research Station of the 16th and 17th January 2018. The workshop was used to develop a project agenda and key issues around changing risks in the Arctic public realm. Whilst this workshop was exploratory, the aim was to identify design challenges to urban space that climate change could bring for soft mobility.  The objective was to develop a research strategy that can develop ways to adapt Arctic settlements to these new environmental risks. The goal is to grow these agendas into research applications and funded research.

    Teachers leading teachers: understanding middle-leaders’ role and thoughts about career in the context of a changed division of labour2018In: School Leadership and Management, ISSN 1363-2434, E-ISSN 1364-2626Article in journal (Refereed)
    Abstract [en]

    This longitudinal study aims to create in-depth knowledge about the phenomena of middle-leadership and career in school by identifying (1) driving forces for seeking and maintaining middle-leading positions, (2) opportunities and difficulties in maintaining the middle-leading role over time, and (3) underlying thoughts of career disclosed in the respondents’ expressions. Five different reasons for seeking middle-leading positions are identified and driving forces for maintaining the position are categorised as either internal reward/non-observable outcomes or external reward/observable outcomes. Furthermore, the results show that different types of difficulties arise in distinct phases and that middle-leaders’ needs for support therefore vary over time. Additionally, the complexity of teachers’/middle-leaders’ career thinking clearly emerges, and implications for practice are discussed.

    Applying the phenotype approach for rosacea to practice and research2018In: British Journal of Dermatology, ISSN 0007-0963, E-ISSN 1365-2133, Vol. 179, no 3, p. 741-746Article in journal (Refereed)
    Abstract [en]

    Background: Rosacea diagnosis and classification have evolved since the 2002 National Rosacea Society expert panel subtype approach. Several working groups are now aligned to a more patient‐centric phenotype approach, based on an individual's presenting signs and symptoms. However, subtyping is still commonplace across the field and an integrated strategy is required to ensure widespread progression to the phenotype approach.

    Objectives: To provide practical recommendations that facilitate adoption of a phenotype approach across the rosacea field.

    Methods: A review of the literature and consolidation of rosacea expert experience.

    Results: We identify challenges to implementing a phenotype approach in rosacea and offer practical recommendations to overcome them across clinical practice, interventional research, epidemiological research and basic science.

    Conclusions: These practical recommendations are intended to indicate the next steps in the progression from subtyping to a phenotype approach in rosacea, with the goals of improving our understanding of the disease, facilitating treatment developments and ultimately improving care for patients with rosacea.

    What's already known about this topic?: Rosacea diagnosis and classification have evolved from a subtype to a phenotype approach. Adoption of the phenotype approach has begun, but more widespread adoption and support across the field are required to ensure a complete transition.

    What does this study add?: We offer practical guidance for clinical practice, interventional and epidemiological research, and basic science, to help overcome challenges and facilitate comprehensive uptake of the phenotype approach in rosacea.

    Airway responsiveness to methacholine and incidence of COPD: an international prospective cohort study2018In: Thorax, ISSN 0040-6376, E-ISSN 1468-3296, Vol. 73, no 9, p. 825-832Article in journal (Refereed)
    Abstract [en]

    Background: It has been debated, but not yet established, whether increased airway responsiveness can predict COPD. Recognising this link may help in identifying subjects at risk.

    Objective: We studied prospectively whether airway responsiveness is associated with the risk of developing COPD.

    Methods: We pooled data from two multicentre cohort studies that collected data from three time points using similar methods (European Community Respiratory Health Survey and Swiss Cohort Study on Air Pollution and Lung and Heart Diseases in Adults). We classified subjects (median age 37 years, 1st–3rd quartiles: 29–44) by their level of airway responsiveness using quintiles of methacholine dose–response slope at the first examination (1991–1994). Then, we excluded subjects with airflow obstruction at the second examination (1999–2003) and analysed incidence of COPD (postbronchodilator FEV1/FVC below the lower limit of normal) at the third examination (2010–2014) as a function of responsiveness, adjusting for sex, age, education, body mass index, history of asthma, smoking, occupational exposures and indicators of airway calibre.

    Results: We observed 108 new cases of COPD among 4205 subjects during a median time of 9 years. Compared with the least responsive group (incidence rate 0.6 per 1000/year), adjusted incidence rate ratios for COPD ranged from 1.79 (95% CI 0.52 to 6.13) to 8.91 (95% CI 3.67 to 21.66) for increasing airway responsiveness. Similar dose–response associations were observed between smokers and non-smokers, and stronger associations were found among subjects without a history of asthma or asthma-like symptoms.

    Conclusions: Our study suggests that increased airway responsiveness is an independent risk factor for COPD. Further research should clarify whether early treatment in patients with high responsiveness can slow down disease progression.

    Megahertz serial crystallography2018In: Nature Communications, ISSN 2041-1723, E-ISSN 2041-1723, Vol. 9, article id 4025Article in journal (Refereed)
    Abstract [en]

    The new European X-ray Free-Electron Laser is the first X-ray free-electron laser capable of delivering X-ray pulses with a megahertz inter-pulse spacing, more than four orders of magnitude higher than previously possible. However, to date, it has been unclear whether it would indeed be possible to measure high-quality diffraction data at megahertz pulse repetition rates. Here, we show that high-quality structures can indeed be obtained using currently available operating conditions at the European XFEL. We present two complete data sets, one from the well-known model system lysozyme and the other from a so far unknown complex of a beta-lactamase from K. pneumoniae involved in antibiotic resistance. This result opens up megahertz serial femtosecond crystallography (SFX) as a tool for reliable structure determination, substrate screening and the efficient measurement of the evolution and dynamics of molecular structures using megahertz repetition rate pulses available at this new class of X-ray laser source.

    Periodic Structures with Higher Symmetries: Analysis and Applications2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    In this thesis, periodic structures with higher symmetries are studied. Their wave propagation characteristics are investigated and their potential applications are discussed. 

    Higher-symmetric periodic structures are described with an additional geometrical operation beyond a translation operator. Two particular types of higher symmetry are glide and twist symmetries. Glide-symmetric periodic structures remain invariant under a translation of half a period followed by a reflection with respect to a glide plane. Twist-symmetric periodic structures remain invariant under a translation along followed by a rotation around a twist axis. 

    In a periodic structure with a higher symmetry, in which the higher order modes are excited, the frequency dispersion of the first mode is dramatically reduced. This feature overcomes the bandwidth limitations of conventional periodic structures. Therefore, higher-symmetric periodic structures can be employed for designing wideband metasurface-based antennas. For example, holey glide-symmetric metallic structures can be used to design low loss, wideband flat Luneburg lens antennas at millimeter waves, which find application in 5G communication systems. In addition, holey glide-symmetric structures can be exploited as low cost electromagnetic band gap (EBG) structures at millimeter waves, due to a wider stop-band achievable compared to non-glide-symmetric surfaces. 

    However, these attractive dispersive features can be obtained if holey surfaces are strongly coupled, so higher-order modes produce a considerable coupling between glide-symmetric holes. Hence, these structures cannot be analyzed using common homogenization methods based on the transverse resonance method. Thus, in this thesis, a mode matching formulation, taking the generalized Floquet theorem into account, is applied to analyze glide-symmetric holey periodic structures with arbitrary shape of the hole. Applying the generalized Floquet theorem, the computational domain is reduced to half of the unit cell. The method is faster and more efficient than the commercial software such as CST Microwave Studio. In addition, the proposed method provides a physical insight about the symmetry of Floquet modes propagating in these structures. 

    Moreover, in this thesis, the effect of twist symmetry and polar glide symmetry applied to a coaxial line loaded with holes is explained. A rigorous definition of polar glide symmetry, which is equivalent to glide symmetry in a cylindrical coordinate, is presented. It is demonstrated that the twist and polar glide symmetries provide an additional degree of freedom to engineer the dispersion characteristics of periodic structures. In addition, it is demonstrated that the combination of these two symmetries provides the possibility of designing reconfigurable filters. Finally, mimicking the twist symmetry effect in a flat structure possessing glide symmetry is investigated. The results demonstrate that the dispersion properties associated with twist symmetry can be mimicked in flat structures.

    Search for supersymmetry in final states with charm jets and missing transverse momentum in 13 TeV pp collisions with the ATLAS detector2018In: Journal of High Energy Physics (JHEP), ISSN 1126-6708, E-ISSN 1029-8479, no 9, article id 050Article in journal (Refereed)
    Abstract [en]

    A search for supersymmetric partners of top quarks decaying as (t) over tilde (1) -> c (chi) over tilde (0)(1)and supersymmetric partners of charm quarks decaying as (c) over tilde (1) -> c (chi) over tilde (0 )(1)where (chi) over tilde (0)(1) is the lightest neutralino, is presented. The search uses 36.1 fb(-1) pp collision data at a centre-of-mass energy of 13 TeV collected by the ATLAS experiment at the Large Hadron Collider and is performed in final states with jets identified as containing charm hadrons. Assuming a 100% branching ratio to c (chi) over tilde (0)(1), top and charm squarks with masses up to 850 GeV are excluded at 95% confidence level for a massless lightest neutralino. For m (t) over tilde (1,(c) over tilde1) - m((chi) over tilde 10)< 100 GeV, top and charm squark masses up to 500 GeV are excluded.

    Ultra-Densification for Future Cellular Networks: Performance Analysis and Design Insights2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The traffic volume in wireless communication has grown dramatically in the lastdecade. Recent predictions indicate such data storm will be even more violent in theshort run. Potential solutions for accommodating the rapid traffic growth can besummed up into three categories: broadening the available bandwidth, improvingthe spectral efficiency, and densifying the infrastructure. In this thesis, we focuson the densification dimension which has been proven to be the most effectiveone in the past. The current gain of network densification mainly comes from cellsplitting, thereby serving more user equipment (UE) simultaneously. This trendwill decelerate as the base station (BS) density gets closer to or even surpassesthe UE density which forms an ultra-dense network (UDN). Thus, it is crucialto understand the behavior and design operations of ultra-densification in futurenetworks.

    An important question for future system design and operating strategy is whichelement is more effective than others. To this end, we start from comparing the effectivenessof densification with spectrum expansion and multi-antenna systems interms of meeting certain traffic demand. Our findings show that deploying more BSsprovides a substantial gain in sparse network but the gain decreases progressively ina UDN. Meanwhile, even with the same area throughput, different combinations ofindividual throughput and UE density lead to different requirements for resources.The diminishing gain appearing in UDNs makes us curious to know if there existsa terminal on the way of densification. Such uncertainty leads to the study onthe asymptotic behavior of densification. By incorporating a sophisticated boundeddual-slope path loss model and practical UE densities in our analysis, we present theasymptotic behavior of ultra-densification: the coverage probability and area spectralefficiency (ASE) have non-zero convergences in asymptotic regions unless theUE density goes to infinity (full load). Our results suggest that network densificationcannot always improve the UE performance or boost the network throughput.

    Next, we shift our focus to the operations of UDNs. We first study BS cooperationsin two UDN scenarios: homogeneous and heterogeneous UDNs which aredistinguished by BS types. In both cases, the cooperation rules become more complicatedthan those in traditional networks. Either channel state information (CSI) orextra delay information needs to be acquired in order to obtain cooperation gains.At last, we investigate the feasibility of applying random beamforming to initialaccess in millimeter-wave (mmWave) UDNs. To our surprise, the simple methodcan provide sufficient performance in both control and data plane, comparing withthe existing schemes. Therefore, it may be unnecessary to develop complex algorithmsfor initial access in future dense mmWave networks. The findings indicatethat UDN may complicate network operations while it may also facilitate the use ofsimple schemes. Our work provides insights into the understanding of the networkdensification and thus paves the way for the operational design of future UDNs.

    Search for Higgs bosons produced via vector-boson fusion and decaying into bottom quark pairs in √s=13  TeV pp collisions with the ATLAS detector2018In: Physical Review D: covering particles, fields, gravitation, and cosmology, ISSN 2470-0010, E-ISSN 2470-0029, Vol. 98, no 5, article id 052003Article in journal (Refereed)
    Abstract [en]

    A search for the b (b) over bar decay of the Standard Model Higgs boson produced through vector-boson fusion is presented. Three mutually exclusive channels are considered: two all-hadronic channels and a photon-associated channel. Results are reported from the analysis of up to 30.6 fb(-1) of pp data at root s = 13 TeV collected with the ATLAS detector at the LHC. The measured signal strength relative to the Standard Model prediction from the combined analysis is 2.5(-1.3)(+1.4) for inclusive Higgs boson production and 3.0(-1.6)(+1.7) for vector-boson fusion production only.

    Uniform Parsing for Hyperedge Replacement Grammars2018Report (Other academic)
    Abstract [en]

    It is well known that hyperedge-replacement grammars can generate NP-complete graph languages even under seemingly harsh restrictions. This means that the parsing problem is difficult even in the non-uniform setting, in which the grammar is considered to be fixed rather than being part of the input. Little is known about restrictions under which truly uniform polynomial parsing is possible. In this paper we propose a low-degree polynomial-time algorithm that solves the uniform parsing problem for a restricted type of hyperedge-replacement grammars which we expect to be of interest for practical applications.

    Surveillance from a Post-Communist Perspective2018In: Surveillance & Society, ISSN 1477-7487, E-ISSN 1477-7487, Vol. 16, no 3, p. 269-276Article in journal (Other academic)
    Abstract [en]

    This special issue is the result of a research initiative that began in 2013, just before the annexation of Crimea by Russia. We, the guest editors, together with Pawel Waszkiewicz at the University in Warsaw, wanted to fill a gap in research on surveillance, which had at that time not yet addressed post-communist societies to any great extent. Today the situation is slightly different, but the need for further research is still pressing. It is therefore with great pleasure that we present a collection of five research articles by both senior and early-stage researchers, as well as a postscript by Professor Emeritus Maria Los, who is one of the few researchers who has written extensively on surveillance-related issues from a post-communist perspective. Below we introduce the special issue with a conceptual overview of post-communist research and its connections to surveillance studies.

    Pion-Pole Contribution to Hadronic Light-By-Light Scattering in the Anomalous Magnetic Moment of the Muon2018In: Physical Review Letters, ISSN 0031-9007, E-ISSN 1079-7114, Vol. 121, no 11, article id 112002Article in journal (Refereed)
    Abstract [en]

    The pi(0) pole constitutes the lowest-lying singularity of the hadronic light-by-light (HLBL) tensor, and thus, it provides the leading contribution in a dispersive approach to HLBL scattering in the anomalous magnetic moment of the muon (g - 2)(mu). It is unambiguously defined in terms of the doubly virtual pion transition form factor, which in principle, can be accessed in its entirety by experiment. We demonstrate that, in the absence of a direct measurement, the full spacelike doubly virtual form factor can be reconstructed very accurately based on existing data for e(+)e(-) -> 3 pi, e(+)e(-)-> e(+)e(-)pi(0), and the pi(0) -> gamma gamma decay width. We derive a representation that incorporates all the low-lying singularities of the form factor, matches correctly onto the asymptotic behavior expected from perturbative QCD, and is suitable for the evaluation of the (g - 2)(mu) loop integral. The resulting value, a(mu)(pi 0-pole) = 62.6(-2.5)(+3.0) x 10(-11), for the first time, represents a complete data-driven determination of the pion-pole contribution with fully controlled uncertainty estimates. In particular, we show that already improved singly virtual measurements alone would allow one to further reduce the uncertainty in a(mu)(pi 0-pole).

    Interspecific transfer of parasites following a range‐shift in Ficedula flycatcher2018In: Ecology and Evolution, ISSN 2045-7758, E-ISSN 2045-7758Article in journal (Refereed)
    Abstract [en]

    Human‐induced climate change is expected to cause major biotic changes in species distributions and thereby including escalation of novel host‐parasite associations. Closely related host species that come into secondary contact are especially likely to exchange parasites and pathogens. Both the Enemy Release Hypothesis (where invading hosts escape their original parasites) and the Novel Weapon Hypothesis (where invading hosts bring new parasites that have detrimental effects on native hosts) predict that the local host will be most likely to experience a disadvantage. However, few studies evaluate the occurrence of interspecific parasite transfer by performing wide‐scale geographic sampling of pathogen lineages, both within and far from host contact zones. In this study, we investigate how haemosporidian (avian malaria) prevalence and lineage diversity vary in two, closely related species of passerine birds; the pied flycatcher Ficedula hypoleuca and the collared flycatcher F. albicollis in both allopatry and sympatry. We find that host species is generally a better predictor of parasite diversity than location, but both prevalence and diversity of parasites vary widely among populations of the same bird species. We also find a limited and unidirectional transfer of parasites from pied flycatchers to collared flycatchers in a recent contact zone. This study therefore rejects both the Enemy Release Hypothesis and the Novel Weapon Hypothesis and highlights the complexity and importance of studying host‐parasite relationships in an era of global climate change and species range shifts.

    Proposals for consideration at IMC11 to modify provisions related solely to fungi in the International Code of Nomenclature for algae, fungi, and plants2018In: IMA Fungus, ISSN 2210-6340, E-ISSN 2210-6359, Vol. 9, no 1, p. I-IIIArticle in journal (Other academic)
    Abstract [en]

    Seven proposals to modify the provisions of the International Code of Nomenclature for algae, fungi, and plants (ICN) at the 11th International Mycological Congress (IMC11) in July 2018 had been received by the proscribed date of 1 March 2018. These proposals are formally presented together here. The topics addressed relate to the clarification of the meaning of "original material" in relation to the typification of sanctioned names, the indication of the nomenclatural status of sanctioned names in author citations, the use of DNA sequences as nomenclatural types, and the possibility of including repository identifiers as an alternative to author citations. A synopsis of the proposals will be provided during April, and the mycological community will be invited to provide a guiding vote up to 10 June 2018. Final decisions on these proposals are to be made following debate at the Fungal Nomenclature Session of IMC11.

    Språkhandlingar i flerspråkiga elevers gruppsamtal: en studie av identitetskonstruktion2018Doctoral thesis, monograph (Other academic)
    Abstract [en]

    The aim of this thesis is to investigate how multilingual fifth-grade pupils in Sweden construct their own and each other’s identities through verbal and non-verbal discourse acts, in group discussions of diary texts without a teacher present. The group discussions were audio and video recorded by the pupils themselves and transcribed by me as a researcher.

    The theoretical foundation of this study is the social constructionist view of identities as multiple, negotiable and flexible processes which are constructed in and through interaction. This is investigated through the participants’ use of discourse acts in the form of initiatives, responses and follow-ups, drawing on the Exchange Structure Model combined with interactional tools from Conversation Analysis. The use of ESM has been expanded in the study for the investigation of non-verbal discourse acts as well. Zimmerman’s framework of the three identity dimensions discourse, situated, and transportable identities has been applied to the analysis of discourse acts, to study the pupils’ identity constructions. Their use of code-switching has been studied in connection with the third identity dimension, here the transportable identity as multilinguals.

    The results show that the pupils as a group cannot be said to make their transportable identities as multilinguals relevant to a high degree in the group discussions. However, some of the pupils make their multilingualism relevant locally, using code-switching as a resource to express feelings, to wield power, and for face-saving effects etc.

    Furthermore, reciprocal contingency between the three dimensions of identity is shown by the pupils’ identity constructions and co-constructions in the group discussions. Discourse identities like initiating diary reporter, confirmation seeker, questioner, responder and endorser are constructed at the micro level of interaction by the participants using verbal and non-verbal discourse acts. These identities build up situated identities together with existing participation frames, such as leader, ‘disser’, ‘group clown’ or reluctant. Both these identity dimensions build up transportable identities as multilinguals together with tacit background information of the participants’ language proficiency. Moreover, the results show how an expanded ESM can be used for analysing both verbal and non-verbal discourse acts and the construction of all three identity dimensions.

    Structure formation at solid/liquid interfaces: Understanding self-assembly and environmental challenges2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The work described in the present dissertation has explored the structure of particles and molecules at solid/liquid interfaces, aiming to understand the physics of self-organizing systems and use this knowledge to address some environmental issues. Surface-sensitive neutron scattering techniques, such as reflectometry and grazing incidence small angle scattering, have been used as the primary tool to investigate structures in proximity to an interface. Some of the challenges in the interpretation of neutron scattering data are discussed, and new methods for analyzing the signal have been proposed.

    It was shown that charged stabilized colloidal particles can self-assemble and form large areas (20 cm2) of crystalline structures, close to a smooth solid surface extending to depths of several micrometers, while orienting themselves into smaller crystallites in the bulk of the suspension. The adsorption of proteins from the seeds of different species of Moringa trees on alumina, silica and polystyrene surfaces was studied, as a means for using proteins from different sources and with different properties, for the water clarification step in the purification process. The seed proteins also showed to enable locking the structure of colloidal particles at the solid/liquid interface, acting as a molecular glue.

    Perfluorinated surfactants (PFASs), widely used in industrial, pharmaceutical and food packing products, have been identified as emerging pollutants, raising a global concern for the environment and wildlife. The present study has shown how PFASs molecules of different fluorocarbon chain length and with different functional groups, create defects in model membranes by partitioning and removing phospholipids from the bilayer, making the bilayer thin and less dense.

    The effect of interface roughness was studied on the lamellar structure of a non-ionic surfactant. Concentrated solutions of the surfactant have been shown to form well-ordered and well-aligned structures at a smooth interface, which could be modified further by simply heating the sample. However it was found that even small roughness, of the same order as the bilayer thickness, can distort the structure to a depth of several micrometers from the interface. Heating the sample could improve the alignment but not as much as that formed at a smooth surface.

    Non-equilibrium dynamics of exactly solvable quantum many-body systems2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Recent experimental advances on ultracold atomic gases and trapped ions have made it possible to simulate exactly solvable quantum systems of interacting particles. In particular, the feasibility of making rapid changes, so-called quantum quenches, to such set-ups has allowed experimentalists to probe non-equilibrium phenomena in closed interacting quantum systems. This, in turn, has spurred a considerable theoretical interest in quantum many-body systems out of equilibrium.

    In this thesis, we study non-equilibrium properties of quantum many-body systems in the framework of exactly solvable quantum field theory in one spatial dimension. Specific systems include interacting fermions described by the Luttinger model and effective descriptions of spin chains using conformal field theory (CFT). Special emphasis is placed on heat and charge transport, studied from the point of view of quench dynamics, and, in particular, the effects of breaking conformal symmetries on transport properties. Examples include the Luttinger model with non-local interactions, breaking Lorentz and scale invariance, and inhomogeneous CFT, which generalizes standard CFT in that the usual propagation velocity v is replaced by a function v(x) that depends smoothly on the position x, breaking translation invariance.

    The quench dynamics studied here is for quantum quenches between, in general, different smooth inhomogeneous systems. An example of this is the so-called smooth-profile protocol, in which the initial state is defined by, e.g., smooth inhomogeneous profiles of inverse temperature and chemical potential, and the time evolution is governed by a homogeneous Hamiltonian. Using this protocol, we compute exact analytical results for the full time evolution of the systems mentioned above. In particular, we derive finite-time results that are universal in the sense that the same relations between the non-equilibrium dynamics and the initial profiles hold for any unitary CFT. These results also make clear that heat and charge transport in standard CFT are purely ballistic.

    Finally, we propose and study an inhomogeneous CFT model with v(x) given by a random function. We argue that this model naturally emerges as an effective description of one-dimensional quantum many-body systems with certain static random impurities. Using tools from wave propagation in random media, we show that such impurities lead to normal and anomalous diffusive contributions to heat transport on top of the ballistic one known from standard CFT.

    Understanding Composition–Structure–Bioactivity Correlations in Bioactive Glasses2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Bioactive glasses integrate with bone/tooth tissues by forming a layer of hydroxy-carbonate apatite (HCA), which mimics the composition of bone mineral. In the current thesis, we investigated composition–structure–bioactivity correlations of phosphosilicate and borophosphosilicate (BPS) glasses. Bioactive phosphosilicate glasses extend the compositional space of the ”45S5 Bioglass®”, which has been in clinical use for decades. Recently developed bioactive BPS glasses with SiO2→B2O3 substitutions transform more completely into HCA and their glass dissolution behaviors can be tuned by varying the relative contents of B and Si. 

    It is known that the average silicate network connectivity NSi and the phosphate content (x(P2O5)) affect the apatite formation (in vitro bioactivity) of phosphosilicate glasses, but the details remain poorly explored. Three series of phosphosilicate glasses were designed by independently varying NSi and x(P2O5). After immersion of the glasses in a simulated body fluid (SBF) for 24 hours, different degrees of their apatite formation were quantified by Fourier-transform infrared (FTIR) spectroscopy. The results revealed that a high P content widened the NSi range that generated optimum amounts of apatite and also mitigated the detrimental effects associated with using glass particles with < 50 μm. The amounts of apatite derived from FTIR agreed with those from 31P magic angle spinning (MAS) nuclear magnetic resonance (NMR) spectroscopy. The growth of apatite at bioactive glass surfaces was found to follow a sigmoidal growth model, in which the precursor phase, amorphous calcium phosphate (ACP), formed in the induction period and then crystallized into HCA in the following proliferation period, with an improvement in the structural ordering of HCA in the maturation period. This formation process closely resembles the apatite precipitated spontaneously from supersaturated Ca/P-containing solutions. The simultaneous growth of ACP and HCA is discussed in conjunction with a previously proposed mechanism for explaining in vitro bioactivity and apatite growth from bioactive glasses. 

    The short- and medium- range structures of bioactive borophosphosilicate (BPS) glasses were investigated by solid-state MAS NMR. Two series of BPS glasses were designed by gradually replacing SiO2 with B2O3 in the 45S5 glass, as well as another base glass featuring a more condensed glass network. As the B2O3 content is increased, the glass networks become more polymerized, together with decreased fractions of the dominating BO3 and orthophosphate units. Borate groups are homogeneously mixed with the isolated orthophosphate groups, while the remaining phosphate groups exhibit a slight preference for bonding to BO4 over SiO4 units. Linkages among borate groups are dominated by B[3]–O–B[4] linkages at the expenses of B[3]–O–B[3] and B[4]–O–B[4] linkages, with the latter B[4]–O–B[4] motifs disfavored yet abundant. A similar fashion of borate mixing was observed in P-free Na/Ca-based borosilicate glasses that span a large compositional space. The content of B[4]–O–B[4] linkages was found to be controlled by the relative fractions of BO4 groups and non-bridging oxygen ions.

    Wearable Solutions for P-Health at Work: Precise, Pervasive and Preventive2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    With a demographic change towards an older population, the structure of the labor force is shifting, and people are expected to work longer within their extended life span. However, for many people, wellbeing has been compromised by work-related problems before they reach the retirement age. Prevention of chronic diseases such as cardiovascular diseases and musculoskeletal disorders is needed to provide a sustainable working life. Therefore, pervasive tools for risk assessment and intervention are needed. The vision is to use wearable technologies to promote a sustainable work life, to be more detailed, to develop a system that integrates wearable technologies into workwear to provide pervasive and precise occupational disease prevention. This thesis presents some efforts towards this vision, including system-level design for a wearable risk assessment and intervention system, as well as specific insight into solutions for in-field assessment of physical workload and technologies to make smart sensing garments. The overall system is capable of providing unobtrusive monitoring of several signs, automatically estimating risk levels and giving feedback and reports to different stakeholders. The performance and usability of current energy expenditure estimation methods based on heart rate monitors and accelerometers were examined in occupational scenarios. The usefulness of impedance pneumography-based respiration monitoring for energy expenditure estimation was explored. A method that integrates heart rate, respiration and motion information using a neuronal network for enhancing the estimation is shown. The sensing garment is an essential component of the wearable system. Smart textile solutions that improve the performance, usability and manufacturability of sensing garments, including solutions for wiring and textile-electronics interconnection as well as an overall garment design that utilizes different technologies, are demonstrated.

    A realist process evaluation within the Facilitating Implementation of Research Evidence (FIRE) cluster randomised controlled international trial: an exemplar2018In: Implementation Science, ISSN 1748-5908, E-ISSN 1748-5908, Vol. 13, no 1, article id 138Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Facilitation is a promising implementation intervention, which requires theory-informed evaluation. This paper presents an exemplar of a multi-country realist process evaluation that was embedded in the first international randomised controlled trial evaluating two types of facilitation for implementing urinary continence care recommendations. We aimed to uncover what worked (and did not work), for whom, how, why and in what circumstances during the process of implementing the facilitation interventions in practice.

    METHODS: This realist process evaluation included theory formulation, theory testing and refining. Data were collected in 24 care home sites across four European countries. Data were collected over four time points using multiple qualitative methods: observation (372 h), interviews with staff (n = 357), residents (n = 152), next of kin (n = 109) and other stakeholders (n = 128), supplemented by facilitator activity logs. A combined inductive and deductive data analysis process focused on realist theory refinement and testing.

    RESULTS: The content and approach of the two facilitation programmes prompted variable opportunities to align and realign support with the needs and expectations of facilitators and homes. This influenced their level of confidence in fulfilling the facilitator role and ability to deliver the intervention as planned. The success of intervention implementation was largely dependent on whether sites prioritised their involvement in both the study and the facilitation programme. In contexts where the study was prioritised (including release of resources) and where managers and staff support was sustained, this prompted collective engagement (as an attitude and action). Internal facilitators' (IF) personal characteristics and abilities, including personal and formal authority, in combination with a supportive environment prompted by managers triggered the potential for learning over time. Learning over time resulted in a sense of confidence and personal growth, and enactment of the facilitation role, which resulted in practice changes.

    CONCLUSION: The scale and multi-country nature of this study provided a novel context to conduct one of the few trial embedded realist-informed process evaluations. In addition to providing an explanatory account of implementation processes, a conceptual platform for future facilitation research is presented. Finally, a realist-informed process evaluation framework is outlined, which could inform future research of this nature.

    Detecting Ponzi Schemes on Ethereum: Towards Healthier Blockchain Technology2018In: WWW '18: Proceedings of the 2018 World Wide Web Conference, ACM Digital Library, 2018, p. 1409-1418Conference paper (Refereed)
    Abstract [en]

    Blockchain technology becomes increasingly popular. It also attracts scams, for example, Ponzi scheme, a classic fraud, has been found making a notable amount of money on Blockchain, which has a very negative impact. To help dealing with this issue, this paper proposes an approach to detect Ponzi schemes on blockchain by using data mining and machine learning methods. By verifying smart contracts on Ethereum, we first extract features from user accounts and operation codes of the smart contracts and then build a classification model to detect latent Ponzi schemes implemented as smart contracts. The experimental results show that the proposed approach can achieve high accuracy for practical use. More importantly, the approach can be used to detect Ponzi schemes even at the moment of its creation. By using the proposed approach, we estimate that there are more than 400 Ponzi schemes running on Ethereum. Based on these results, we propose to build a uniform platform to evaluate and monitor every created smart contract for early warning of scams.

    Introduktionsverksamhet för nyanlända elever i grundskolans tidiga år2018Licentiate thesis, monograph (Other academic)
    Abstract [en]

    Children who migrate to Sweden are usually introduced to the Swedish school through some kind of introduction programme in their new community. This study examines the experiences of newly arrived children participating in school introduction in the early school years, as well as the experiences of the teachers and principals working with the programme. In the community in which this study is situated, newly arrived children participate in a special school unit where the goal is to map their experiences and skills from former education, and where the teaching of Swedish as a second language is seen as an important part of the introduction.

    Forty-two interviews (40 individual and 2 pairs) were conducted with principals, teachers and newly arrived children (ages appropriate for Years 2, 3, 4 and 5 in elementary school). Employing a social constructivist perspective, together with inspiration from Critical Discourse Analysis, the study aimed at outlining the discourses the participants draw on when speaking about the school introduction and how these discourses affect the participants’ positioning of themselves and other participants in the school practice. Fairclough’s theory of discourse (1992, 2001) provides an understanding of how participants experience being part of the school introduction as well as their own and other participants’ positions in the school practice due to ambient discourses.

    The results indicate that four discourses dominate the practice and affect the participants’ view of each other and themselves as well as their possibilities to impact the practice and their own situation as being a part of it. The four discourses that were identified are described as 1) the Swedish language as a key to success in school, 2) the adjustment of behaviour as a key to success in school, 3) the substantial immigration as a challenge, and 4) heed.

    When robot personalisation does not help: Insights from a robot-supported learning study2018In: 27th IEEE International Symposium on Robot and Human Interactive Communication (RO-MAN), 2018Conference paper (Refereed)
    Abstract [en]

    In the domain of robotic tutors, personalised tutoring has started to receive scientists' attention, but is still relatively underexplored. Previous work using reinforcement learning (RL) has addressed personalised tutoring from the perspective of affective policy learning. However, little is known about the effects of robot behaviour personalisation on user's task performance. Moreover, it is also unclear if and when personalisation may be more beneficial than a robot that adapts to its users and the context of the interaction without personalising its behaviour. In this paper we build on previous work on affective policy learning that used RL to learn what robot's supportive behaviours are preferred by users in an educational scenario. We build a RL framework for personalisation that allows a robot to select verbal supportive behaviours to maximise the user's task progress and positive reactions in a learning scenario where a Pepper robot acts as a tutor and helps people to learn how to solve grid-based logic puzzles. A between-subjects design user study showed that participants were more efficient at solving logic puzzles and preferred a robot that exhibits more varied behaviours compared with a robot that personalises its behaviour by converging on a specific one over time. We discuss insights on negative effects of personalisation and report lessons learned together with design implications for personalised robots.

    Seafood Life Cycle Inventory database : Methodology and Principles and Data Quality Guidelines2018Report (Other academic)
    Abstract [en]

    An increasing awareness about the important role of food, in particular animal-based foods including seafood, for global environmental impacts has led to a need of producers as well as retailers to communicate environmental impacts of raw materials and products through the food chain. This is demonstrated by new requirements to document the environmental footprints of products, e.g. by certification schemes and policies. The EU policy for sustainable development with its "single market for green products" is one example, aiming for documenting the environmental footprint of products on the EU market according to the Product Environmental Footprint (PEF) method. The goal is to enable consumers, retailers, producer, regulators and policy makers to make conscious choices and establish drivers for reducing environmental impacts throughout product supply chains.

    To be able to live up to these new requirements, representative data of high quality is needed, something which has largely been missing for seafood products. To make high-quality, representative data on the resource use and environmental impacts caused by seafood products (including biomass used directly or indirectly for feed) available, the Norwegian seafood industry initiated a pilot project. The project defined a recommended method and structure for data collection and used this method to collect available data for a number of pilot cases. The method for data collection is presented in this document and can, together with the pilot data sets made available through the project, be used by the industry as a basis for a broader data collection to create an expanded seafood LCI database.

    Screening test methods for determination of fire spalling of concrete2018Report (Other academic)
    Abstract [en]

    The fire resistance of concrete structures is generally good, but for some types of concrete fire spalling can reduce the fire resistance significantly. Therefore, methods are needed to predict whether a concrete will spall when exposed to fire and the severity of spalling.

    The objective of the present project was to develop an intermediate scale test method for the evaluation of the spalling behavior of concrete. The test method shall be cost effective and enable screening of different concretes before a full scale approval test is performed. A number of different intermediate scale test methods have been evaluated regarding the precision to reproduce the spalling behavior of that observed in full scale tests.

    Of the different test specimen shapes and methods, a circular test specimen where the concrete is casted in a steel tube has shown the best correlation to the full scale tests performed. This specimen is easy to produce, and the fire test can be performed on a small furnace.

    Abstract [en]

    The project has been involved in developing a flue gas recirculation system aimed at reducing emissions of NO

    x and dust, as well as extending the life of the material in a pellet burner. Installation of a flue gas recirculation system and combustion tests have been performed in a laundry in Bengtsfors, which has a pellet-fired boiler with two janfire burners of 750 kW each. The results of the tests showed that the flue gas recirculation had an impact on NOx emissions. These decreased by about 17-18% in wood pellets combustion and by 10% in combustion of nitrogen rich agro fuel pellets in comparison to non-flue gas recirculation. With flue gas recirculation, the combustion furnace temperatures decreased by 85-105 oC for wood pellets and about 70 oC for agro fuel pellets.

    For potential users, especially in the industry, which consider bio-oil as well as pyrolysis oil as a fuel alternatives in the future, in-depth knowledge of its technical and economic conditions in various industrial applications is required. To verify which requirements these oils sets on the combustion technology more combustion tests in potential burners are needed to clarify any technical development. To minimize any problems that may arise with pyrolysis oil, from delivery to storage and combustion, the available knowledge about the use of common bio-oils should be used. The overall objective of this project is to investigate the possibilities to use pyrolysis oil in various industrial applications.

    Cyclic fractionation process for Saccharina latissima using aqueous chelator and ion exchange resin2017In: Journal of Applied Phycology, ISSN 0921-8971, E-ISSN 1573-5176, Vol. 29, no 6Article in journal (Refereed)
    Abstract [en]

    A new approach to process Saccharina latissima algal biomass was developed using sodium citrate and a polyvalent cation-specific resin to sequentially extract the alginate into several usable fractions. The fractionation was performed in a cyclic manner, utilizing a stepwise removal of the native polyvalent ions present in the algae to isolate fractions of alginate with different solubility in the presence of these ions. Sodium citrate was used in different concentrations in the extraction solution to remove polyvalent cations to adjust the alginate liberation while AMBERLITE IRC718 resin was added to further remove these ions and regenerate the extraction solution. Alginate was recovered by acid precipitation and analyzed for its uronic acid composition and molecular weight, and the carbohydrate compositions of the insoluble and soluble parts of the algal biomass residue were determined. Finally, the fractionation method was assessed with a life cycle analysis to determine the energy and water efficiency as well as the greenhouse gas emissions and the results were compared to conventional alkaline extraction. The results indicate that the energy and water use as well as the emissions are considerably lower for the cyclic extraction in comparison with the conventional methods.

    The ultimate challenge or just common sense : The present practices and future opportunities to increase the utilization of livestock manure as organic fertilizer in North West Russia2017Report (Other academic)

    The ultimate challenge or just common sense

    The present practices and future opportunities to increase the utilization of livestock manure as organic fertilizer in North West Russia

    The risk of nutrient contamination of surface- and groundwater’s from livestock farming has been one of the issues to address in international cooperation initiatives in the Baltic Sea Region during the recent decade. In particular, international initiatives targeting North West Russia in the 2000-2010’s by HELCOM and NEFCO and as bilateral cooperation with Russia by Finland and Sweden have assessed the severity of the threat, have introduced technical solutions to process livestock manure and have explored the market potential for fertilizer products made through processing of livestock manure. However, a comprehensive resolution to the growing problem still remains a long term goal and many of the barriers to increase manure processing and organic fertilization – poor economic incentives and lack of proven cost-efficient technologies – still prevail.

    In Russia, ongoing adaptation of state support to agriculture as part of the WTO membership brings about indirect area-based farm support and increased share of support to investments in farm infrastructure, rural development and in management of health, hygienic and environmental aspects. These represent positive opportunities for increasing sustainable manure management and the proportion of manure-based fertilization. The Technological Regulations (TR) instrument introduced in 2008, enhanced enforcement and systematic introduction of BAT in Russian agriculture, provide a set of management tools which has good potential to be effective for the administration and be accepted by the agricultural companies. At the same time, there is a risk that the increasing concentration of livestock, in particular poultry production in Leningrad Oblast narrows alternative paths for sustainable manure management and is leading to a situation in which only large scale technological solutions may prove to be viable in order to solve the issue on the regional scale.

    This report reviews the current environment in North West Russian Federation to advance sustainable animal manure management and reflects this against the EU context with related examples from Latvia. The report concludes that a sustainable future for North West Russian agriculture relies on the overall sustainability of the enterprises and that regulative and subsidy measures should reinforce the positive link between economic and environmental benefit. Spatial aspects on the territorial level should be

    addressed as the location of agricultural enterprises both relative to each other and relative to human settlements have increasing importance from the perspective of environmental, health and biosecurity implications. Thirdly, Russia’s adaptation to the WTO framework, the process of implementing BAT in agriculture and the TR instrument to support holistic farm specific solutions provide a range of interesting topics for future international cooperation on both technical and policy levels.

    Multicomponent fractionation of Saccharina latissima brown algae using chelating salt solutions2016In: Journal of Applied Phycology, ISSN 0921-8971, E-ISSN 1573-5176, Vol. 28, no 4, p. 2561-2574Article in journal (Refereed)
    Abstract [en]

    A fractionation strategy for Saccharina latissima algal biomass was developed utilizing chelating extraction salt solutions to mediate the liberation of algal components. Alginate, cellulose, laminarin, mannitol, protein, and inorganic salts were quantified in the fractions to reveal their individual dissolution patterns. Chelation power was identified as a key parameter for liberating alginate and increasing the yield of extracted components. The most efficient fractionation was achieved using aqueous sodium citrate as the extraction solution, producing an alginate-rich soluble fraction and a salt-poor insoluble fraction rich in cellulose and protein. Extractions at decreased pH were shown to be beneficial because they decreased the M/G ratio of the extracted alginate and concentrated the protein in the insoluble fraction from which it can easily be recovered; these effects could be achieved by switching the traditional sodium carbonate extraction solution with salts that have chelation capacity at lower pH. A cyclic extraction demonstrated that the sodium citrate solution can be reused for multiple alginate extractions with the buildup of the concentrations of other valuable components in the solution.

    Фрагмент средневековой рукописи Минеи в Упсале2013In: Slovo : Journal of Slavic Languages and Literatures, ISSN 0348-744X, E-ISSN 2001-7359, Vol. 54, p. 164-180Article in journal (Refereed)
    Abstract [en]

    In 1991 the present author found, in the collection of old Slavic prints at the Uppsala University Library, a hitherto unobserved parchment fragment of Slavic origin. The fragment had been used as binding material in a psalter, printed in Lviv in 1615. It was revealed to consist of two leaves, having possibly once constituted a bifolium. The fragment is published here with introductory comments.

    The author’s analysis dates the fragment to the 13th century. The language is Russian Church Slavonic with some south-western (“Ukrainian”) traits. The text consists of a number of hymns, all connected to the baptism of Christ. Most of these hymns are part of a canon sung on the Forefeast of the Theophany of our Lord, and the redaction appears quite old. It is not fully clear which type of liturgical book the fragment stems from, but the hymns are most likely taken from a Menaion (Минея служебная). Nothing of the kind has previously been found in Sweden.

    Probing Catalytic Reaction Mechanisms of Biomimetic Diiron Complexes with Time-resolved Absorption Spectroscopy2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Directed design of improved molecular catalysts for hydrogen evolution reactions relies on rational benchmarking based on detailed understanding about the mechanism of catalysis. Specifically, investigation of multi-electron redox catalysis, with structural characterization of catalytic intermediates, combined with the kinetics of their transformations, can reveal the rate-limiting step of the overall reaction, possible degradation pathways and the function of structural motives. However, direct spectroscopic observation of catalytic intermediates is in most cases not available due to the rapid turnover of efficient catalysts.

    In this thesis, time-resolved absorption spectroscopy with UV-Vis and mid-IR detection was used to identify catalytic reaction intermediates and account for kinetics relevant to elementary reactions steps of H2 formation on a nanosecond to second time scale. For a class of FeIFeI (S-R-S)(CO)6-n(PMe3)n complexes (R = propyl, benzyl or azapropyl), inspired by the active site of FeFe-hydrogenase, the key intermediates formed in different catalytic pathways have been characterized. These complexes typically feature very similar geometry coordination, but show different structural rearrangement upon reduction. This might be applied to elucidate their differences in protonation dynamics. Protonation kinetics of singly reduced species, forming bridging hydride, indicate a direct proton transfer step in the FeIFe0 state, in contrast to that of the neutral complex (FeIFeI state) with phosphine ligands (PMe3) in which the hydride formation is likely mediated by one of the CO-ligands, as had been proposed. In catalysis of FeFe-hydrogenase, the amine function of the bridgehead is known to assist enzymatic H2 formation by proton shuttling. The same role in catalysis by synthetic diiron complex with the azapropyl bridgehead had been proposed. However, our results show that for the synthetic complex, the aza-group has no role as proton shuttle in the hydride formation in the FeIFe0 state. Instead, the effect of aza protonation is to lower the catalyst overpotential, but does not slows down the hydride formation by external proton.  For complex with benzyl bridgehead, the rigid and unsaturated bridging ligand generally lower the reduction potential and stabilize the reduced forms. This allows to characterize the overall catalytic processes, i.e exact structure of hydride intermediate, turnover process, etc.

    Ukrainian Colour Concepts for Blue2013In: Slovo : Journal of Slavic Languages and Literatures, ISSN 0348-744X, E-ISSN 2001-7359, Vol. 54, p. 150-163Article in journal (Refereed)
    Abstract [en]

    A much-studied area, colour categorization has received renewed attention in cognitive linguistics. A promising line of research is the reconstruction of colour concepts. Specifically, the goal is to discover points of reference used by a linguistic community for different colours. The colour system of Ukrainian is special in that it has as many as three basic words (synij, blakytnyj and holubyj) for what is generally called blue in English. This paper analyzes experimental and corpus data and offers a reconstruction of their referential models. The Ukrainian colour names under study are shown to have a dominant reference point (a clear sky for all three words) and secondary ones. Relevant aspects of typical observation situations and other contributing factors are discussed.

    Многоязычное языковое сообщество: русскоязычные иммигранты Финляндии2013In: Slovo : Journal of Slavic Languages and Literatures, ISSN 0348-744X, E-ISSN 2001-7359, Vol. 54, p. 133-149Article in journal (Refereed)
    Abstract [en]

    This article examines the multilingualism of a new generation of Russian-speaking immi- grants in Finland. The main focus in the article is on immigrants’ use of and competency in Finnish and Russian, as well as the meaning of these languages for persons immigrating at different stages in their lives. The article also describes how these immigrants view their lin- guistic situation and possibilities for maintaining and developing different languages. Finally, conclusions will be drawn about the possibilities for, and constraints on, the multilingualism of speakers of Russian in Finnish society. This article is based on two studies: a longitudinal case-study on young Russian-speaking immigrants, and a study of working-age Russian- speaking migrants within the project “Transforming Professional Integration” (ISIS). The data consist of thematic interviews with Russian-speaking migrants living in Finland. Principles of qualitative content analysis were applied in analyzing the data.

    “It’s wonderful to be a Soviet writer!” Vera Inber’s Northern Journey in 19342013In: Slovo : Journal of Slavic Languages and Literatures, ISSN 0348-744X, E-ISSN 2001-7359, Vol. 54, p. 19-48Article in journal (Refereed)
    Abstract [en]

    In the autumn of 1934, the Soviet writer Vera Inber (1890-1972) made a three months’ journey through the Nordic countries. The journey was undertaken on the invitation of Swedish and Norwegian student organizations and friendship societies. She met with journalists and writer-colleagues, gave talks in Stockholm, Uppsala, Oslo, Bergen, Copenhagen and Aarhus and collected material for a planned book about life in modern Scandinavia. In numerous interviews she praised the victories of socialism, the successful solution to the “women’s question” and the visible role of writers in the Soviet Union. When stating that “it’s wonderful to be a Soviet writer”, Inber was in fact at this point of her career passing from being a talented, highly original author of short stories and poems to becoming an obedient tool in the hands of the Communist Party.
