    Detecting Rhetorical Figures Based on Repetition of Words: Chiasmus, Epanaphora, Epiphora2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis deals with the detection of three rhetorical figures based on repetition of words: chiasmus (“Fair is foul, and foul is fair.”), epanaphora (“Poor old European Commission! Poor old European Council.”) and epiphora (“This house is mine. This car is mine. You are mine.”). For a computer, locating all repetitions of words is trivial, but locating just those repetitions that achieve a rhetorical effect is not. How can we make this distinction automatically?

     First, we propose a new definition of the problem. We observe that rhetorical figures are a graded phenomenon, with universally accepted prototypical cases, equally clear non-cases, and a broad range of borderline cases in between. This makes it natural to view the problem as a ranking task rather than a binary detection task. We therefore design a model for ranking candidate repetitions in terms of decreasing likelihood of having a rhetorical effect, which allows potential users to decide for themselves where to draw the line with respect to borderline cases.

     Second, we address the problem of collecting annotated data to train the ranking model. Thanks to a selective method of annotation, we can reduce by three orders of magnitude the annotation work for chiasmus, and by one order of magnitude the work for epanaphora and epiphora. In this way, we prove that it is feasible to develop a system for detecting the three figures without an unsurmountable amount of human work.

     Finally, we propose an evaluation scheme and apply it to our models. The evaluation reveals that, even with a very incompletely annotated corpus, a system for repetitive figure detection can be trained to achieve reasonable accuracy. We investigate the impact of different linguistic features, including length, n-grams, part-of-speech tags, and syntactic roles, and find that different features are useful for different figures. We also apply the system to four different types of text: political discourse, fiction, titles of articles and novels, and quotations. Here the evaluation shows that the system is robust to shifts in genre and that the frequencies of the three rhetorical figures vary with genre.

    Life cycle inventory data from farms: Need for secondary and life cycle inventory data fro use in Product Environmental Footprint (PEF) of livestock products in The Nordic Countries2017Report (Other academic)
    Abstract [en]

    As part of the Sustainable Production and Consumption strategy, The European Commission is establishing the framework for a harmonised assessment of the environmental impact of products (PEF) based on a life cycle approach. This also includes methodologies for foods, including livestock products. The farming stage is by far the largest contributor to the environmental profile of such foods, so it is important to have sound data representing this stage. This report identifies in a Nordic context what primary farm activity data that is perceived relatively easy to collect and what supplementary data and life cycle inventory analysis data (LCI) that are needed. It is concluded that there is in particular a need for LCI’s for feeds produced in the Nordic countries and for recruitment animals in different livestock systems, and a relevant granularity for such datasets are proposed.

    Cd2+ and Zn2+ sorption on apatite in the presence of EDTA and humic substance2013In: Proceedings of the 16th International Conference on Heavy Metals in the Environment / [ed] Pirrone, N, EDP Sciences, 2013, 01008Conference paper (Refereed)
    Abstract [en]

    The sorption of Cd2+ and Zn2+ on hydroxyapatite [HAP-Ca-10(PO4)(6)(OH)(2)] and fluorapatite [FAP-Ca-10(PO4)(6)(F)(2)] with different specific surface area and stoichiometry was investigated in batch experiments in the pH range 4 to 11 (25 degrees C; 0.1 M KNO3). The impact of different conditions was concerned: solution pH, the presence of complexing ligands (EDTA and humic substance) and competing metal ions, as well as reaction kinetic and equilibrium conditions. To evaluate the reversibility of Cd2+ sorption onto HAP, desorption characteristics in water, Ca, EDTA, and HUM-solutions were determined. Additionally to solution analysis the surface composition of solid phases was analysed by X-Ray Photoelectron Spectroscopy (XPS). The information from the chemical analyses was used to design an equilibration model that takes into account dissolution, surface potential, solution and surface complexation, as well as possible phase transformations. It was revealed that apatites effectively sorb Cd2+ and Zn2+ by ion exchange reactions on surface by formation of new surface phases. Using XPS the formation of a Me-enriched HAP surface was found, which was interpreted as the formation of a solid solution with the general formula: Ca8.4-xMex(HPO4)(1.6)(PO4)(4.4)(OH)(0.4). In a binary solution (Cd+ Zn) the competition of metals reduced individual sorbed amount compared with the single component solutions but the total adsorption maximum was approximately constant. The presence of EDTA reduces the metal sorption on apatite due to [CdEDTA](2)- and [ZnEDTA] 2-complexes and increases apatite solubility due to [CaEDTA](2)-complex formation. The dissolved humic substance was bound on apatite in suspensions but the amount of Cd2+ bound was not changed. The results showed that the solution pH and the presence of complexing ligands have a significant effect on heavy metal sorption on apatite and must be considered if apatites are used as remediation agent. The proposed model can be used to predict apatite dissolution and surface phase transformations in the presence of metal ions and EDTA.

    Micropollutants in wastewater in four arctic cities - is the treatment sufficient?2017Book (Other academic)
    Abstract [en]

    The four Nordic cities included in the present study form a gradient both in climate, from oceanographic temperate in Tórshavn at 620 N to arctic in Tromsø at 69.70N, and in population, from less than 6000 inhabitants in Sisimiut to close to 120 000 in Reykjavík. The cities are different and far apart but products from the sea has been mainstay to the economy and societal development. Thus, the management of sewage from the municipalities must maintain a clean and healthy marine environment. The wastewater treatment varies, from screening on fine mesh, via septic tank based purification solutions, to no purification at all. We measured the contaminants in wastewater streams and in recipient samples, and with that in hand assessed whether the wastewater treatment appeared sufficient, and if not, which mitigating solutions could be relevant for wastewater purification optimisation.

    Collaborative filmmaking: Reflection on the artistic development project about devising film: Filmdevising2016Artistic output (Refereed)
    Abstract [en]

    Collaborative filmmaking:

    The starting point for this artistic development project has been the question of a democratic and power-critical process is possible in a film team work. The project has been divided into two phases, a research phase that resulted in a report on how existing, state-of-the-art performing arts and collaborative film processes can look like. The second stage of the project has been a collaborative workshop where I, together with a group of professionally active filmmakers and actors, studied this form of work. The project is presented in the form of film material from the workshop work and a reflective text of the process.

    Det nordiske budsjettet spiller en sentral rolle som et verktøy for styring og prioritering for det nordiske samarbeidet. Store samfunnsmessige utfordringer har også betydning for det nordiske samarbeidet. Det gjelder hvordan vi eksempelvis møter konsekvenser av geopolitiske endringer, migrasjon og klimautfordringer. Økt internasjonal oppmerksomhet omkring nordiske løsninger representerer nye muligheter. Dette krever et dynamisk og fleksibelt samarbeid hvor budsjettet er et viktig redskap for årealisere nye løsninger på nye utfordringene.

    A practical guide to build de-novo assemblies for single tissues of non-model organisms: the example of a Neotropical frog2017In: PeerJ, ISSN 2167-8359, E-ISSN 2167-8359, Vol. 5, e3702Article in journal (Refereed)
    Abstract [en]

    Whole genome sequencing (WGS) is a very valuable resource to understand the evolutionary history of poorly known species. However, in organisms with large genomes, as most amphibians, WGS is still excessively challenging and transcriptome sequencing (RNA-seq) represents a cost-effective tool to explore genome-wide variability. Non-model organisms do not usually have a reference genome and the transcriptome must be assembled de-novo. Weused RNA-seq to obtain the transcriptomic profile for Oreobates cruralis, a poorly known South American direct-developing frog. In total, 550,871 transcripts were assembled, corresponding to 422,999 putative genes. Of those, we identified 23,500, 37,349, 38,120 and 45,885 genes present in the Pfam, EggNOG, KEGG and GO databases, respectively. Interestingly, our results suggested that genes related to immune system and defense mechanisms are abundant in the transcriptome of O. cruralis. We also present a pipeline to assist with pre-processing, assembling, evaluating and functionally annotating a de-novo transcriptome from RNA-seq data of non-model organisms. Our pipeline guides the inexperienced user in an intuitive way through all the necessary steps to build de-novo transcriptome assemblies using readily available software and is freely available at: https://github. com/biomendi/TRANSCRIPTOMEASSEMBLY- PIPELINE/wiki.

    Cryogenian evolution of stigmasteroid biosynthesis2017In: Science Advances, ISSN 0036-8156, E-ISSN 2375-2548, Vol. 3, no 9, e1700887Article in journal (Refereed)
    Abstract [en]

    Sedimentary hydrocarbon remnants of eukaryotic C-26-C-30 sterols can be used to reconstruct early algal evolution. Enhanced C-29 sterol abundances provide algal cellmembranes a density advantage in large temperature fluctuations. Here, we combined a literature review with new analyses to generate a comprehensive inventory of unambiguously syngenetic steranes in Neoproterozoic rocks. Our results show that the capacity for C-29 24ethyl- sterol biosynthesis emerged in the Cryogenian, that is, between 720 and 635 million years ago during the Neoproterozoic Snowball Earth glaciations, which were an evolutionary stimulant, not a bottleneck. This biochemical innovation heralded the rise of green algae to global dominance of marine ecosystems and highlights the environmental drivers for the evolution of sterol biosynthesis. The Cryogenian emergence of C-29 sterol biosynthesis places benchmark for verifying older sterane signatures and sets a new framework for our understanding of early algal evolution.

    Extreme genome diversity in the hyper-prevalent parasitic eukaryote Blastocystis2017In: PLoS biology, ISSN 1544-9173, E-ISSN 1545-7885, Vol. 15, no 9, e2003769Article in journal (Refereed)
    Abstract [en]

    Blastocystis is the most prevalent eukaryotic microbe colonizing the human gut, infecting approximately 1 billion individuals worldwide. Although Blastocystis has been linked to intestinal disorders, its pathogenicity remains controversial because most carriers are asymptomatic. Here, the genome sequence of Blastocystis subtype (ST) 1 is presented and compared to previously published sequences for ST4 and ST7. Despite a conserved core of genes, there is unexpected diversity between these STs in terms of their genome sizes, guanine-cytosine (GC) content, intron numbers, and gene content. ST1 has 6,544 protein-coding genes, which is several hundred more than reported for ST4 and ST7. The percentage of proteins unique to each ST ranges from 6.2% to 20.5%, greatly exceeding the differences observed within parasite genera. Orthologous proteins also display extreme divergence in amino acid sequence identity between STs (i.e., 59%-61% median identity), on par with observations of the most distantly related species pairs of parasite genera. The STs also display substantial variation in gene family distributions and sizes, especially for protein kinase and protease gene families, which could reflect differences in virulence. It remains to be seen to what extent these inter-ST differences persist at the intra-ST level. A full 26% of genes in ST1 have stop codons that are created on the mRNA level by a novel polyadenylation mechanism found only in Blastocystis. Reconstructions of pathways and organellar systems revealed that ST1 has a relatively complete membrane-trafficking system and a near-complete meiotic toolkit, possibly indicating a sexual cycle. Unlike some intestinal protistan parasites, Blastocystis ST1 has near-complete de novo pyrimidine, purine, and thiamine biosynthesis pathways and is unique amongst studied stramenopiles in being able to metabolize alpha-glucans rather than beta-glucans. It lacks all genes encoding heme-containing cytochrome P450 proteins. Predictions of the mitochondrion-related organelle (MRO) proteome reveal an expanded repertoire of functions, including lipid, cofactor, and vitamin biosynthesis, as well as proteins that may be involved in regulating mitochondrial morphology and MRO/endoplasmic reticulum (ER) interactions. In sharp contrast, genes for peroxisome-associated functions are absent, suggesting Blastocystis STs lack this organelle. Overall, this study provides an important window into the biology of Blastocystis, showcasing significant differences between STs that can guide future experimental investigations into differences in their virulence and clarifying the roles of these organisms in gut health and disease.

    Automatic Platelets Counter for Supporting Dengue Case Detection in Primary Health Care in Indonesia2013In: Medinfo 2013: proceedings of the 14th World Conference on Medical and Health Informatics, Pts 1 and 2 / [ed] Lehmann, CU Ammenwerth, E Nohr, C, IOS Press, 2013, 585-588 p.Conference paper (Refereed)
    Abstract [en]

    Dengue fever is a major problem in many developing countries, including Indonesia. Laboratory examination is used to diagnose dengue infection and to monitor disease progression. Hematology tests, such as platelet count, are also used for timely recognition of the development of severe dengue. In primary health care centers platelet counting is typically performed manually, which is labor intensive and requires an experienced laboratory technician. To address this challenge, we have developed an automatic platelet counter for primary health care and resource-poor settings. The technology is based on a conventional microscope equipped with a digital camera linked to a personal computer, which can capture and analyze microscope images of blood samples. To evaluate the accuracy of the technology, it was compared to platelet counts performed manual by an experienced laboratory technician. Statistical analysis shows no difference between the techniques with a kappa coefficient of 0.6. This method is judged to have great potential as a tool to help primary health centers and other facilities with limited resources to deal with the burden of dengue.

    Capability Driven Development of Context-aware Enterprise Applications – Challenges, Approach and Experiences2015In: 5th Enterprise Engineering Working Conference, CIAO! Network , 2015Conference paper (Refereed)
    Abstract [en]

    Enterprises are facing the need to adapt their businesses according to various situations in which their applications need to be used. To answer this challenge an EU FP7 project “Capability as a Service in digital enterprises” (CaaS) has been initiated. The aim of CaaS is to support the capture and analysis of changing business context in the design of information systems (IS) using the capability notion. Capability is seen as the ability and capacity that enables an enterprise to achieve a business goal in a certain context. The key rationale behind a capability driven approach is to capture the dependence of organizational and IS designs on application context and to provide explicit support for run-time adjustments according to changes in the application situation. The CaaS project is developing a methodology and a tool environment for capability driven development. We envision to further advance the service oriented paradigm and to develop context aware business capabilities by using Enterprise Modelling techniques as a starting point of the development process, capability design patterns for reuse of best practices, as well as composition of required capabilities and algorithms for run-time adjustment. This talk will address the main principles of the capability driven development methodology, as well as present the current experiences of capability design in three use case companies of the CaaS project – SIV AG (Germany) for business process outsourcing, Fresh T Limited (UK) for compliance management, and Everis (Spain) for capability management in e-government platforms.

    "Social Issues Open up Social Studies": Upper Secondary Teachers´Conceptions of, and Didactical Reflections upon the Subject2017In: Nordidactica: Journal of Humanities and Social Science Education, ISSN 2000-9879, no 2017:2, 1-24 p.Article in journal (Refereed)
    Abstract [en]

    This article identifies and discusses conceptions of the Swedish school subject social studies in upper secondary school through an empirical study consisting of qualitative interviews with seven teachers of social studies. The curriculum declares that teaching social studies shall be done with “social issues as the point of departure”. The analysis focuses on the teachers’ didactical reflections on the subject specific concept of social issues in relation to their own teaching practice. Conclusions that are made are that the approach of teaching social studies with ‘social issues as the  point of departure’ leads to conceptions of social studies as being a subject that is open to the unexpected and that transcends its borders, and with its purpose seen as its content, or put differently: the ‘what’ defined through, or as, its ‘why’. It seems more relevant to discuss what the social issues, as a didactical concept, do to the subject rather than what they are. The very quest for a certain core in the subject is being challenged. A reflection on these results leads to a discussion on the potential intrinsic value of social issues in teaching social studies.

    SIMAIRscenario - ett modellverktyg för bedömning av luftföroreningars hälsoeffekter och kostnader2011Report (Other academic)
    Abstract [en]

    SIMAIRscenario is a new web based tool developed for estimation of health impacts and economic benefits occurring when populations experience changes in air quality. It is a new member of the SIMAIR family, which is a national air quality system for Sweden. In SIMAIRscenario following can be done: 1. Import air quality data fields from different dispersion models such as SIMAIR and Airviro. 2. Process air quality data by different mathematical operators. 3. Import and store detailed population data and process them by different mathematical operators. Population data for the year 2008 divided in different age groups with the resolution of 100*100 meters for the whole country is now available. 4. Presentation of air quality and population data on maps. 5. Perform exposure calculations and presents results on maps and in tables. 6. Perform health impact assessments and valuation of these impacts in monetary terms. The air quality change is calculated as the difference between the starting air pollution level, also called the baseline, and the air pollution level after some change, also called the scenario. The scenario can be described as a major change in activities or technical solutions in an urban or regional area or a regulation leading to different emissions to the atmosphere compare to the baseline.

    Working environment and work retention2017Book (Other academic)
    Abstract [en]

    The project shows that the working environment is rarely the sole cause of early retirement, but working environment factors may explain a large fraction of the transition to disability pension in particular. Several working environment predictors of early retirement are well-documented in the Nordic countries, but workplace policies and activities to retain older workers rarely aim to improve the working environment. There may be great potentials in developing workplace interventions which combine prevention of working environment risk factors (e.g. risk factors for accidents, strenuous work/high physical work demands, insufficient recovery between work shifts, quantitative work demands, conflicts at work and bullying/harassment, and age discrimination) with increment of job satisfaction through increased control/influence, possibilities for development and recognition from management.

    MR-OPERA: A Multicenter/Multivendor Validation of Magnetic Resonance Imaging-Only Prostate Treatment Planning Using Synthetic Computed Tomography Images2017In: International Journal of Radiation Oncology, Biology, Physics, ISSN 0360-3016, E-ISSN 1879-355X, Vol. 99, no 3, 692-700 p.Article in journal (Refereed)
    Abstract [en]

    Purpose: To validate the dosimetric accuracy and clinical robustness of a commercially available software for magnetic resonance (MR) to synthetic computed tomography (sCT) conversion, in an MR imaginge-only workflow for 170 prostate cancer patients.

    Methods and Materials: The 4 participating centers had MriPlanner (Spectronic Medical), an atlas-based sCT generation software, installed as a cloud-based service. A T2-weighted MR sequence, covering the body contour, was added to the clinical protocol. The MR images were sent from the MR scanner workstation to theMriPlanner platform. The sCT was automatically returned to the treatment planning system. Four MR scanners and 2 magnetic field strengths were included in the study. For each patient, a CT-treatment plan was created and approved according to clinical practice. The sCT was rigidly registered to the CT, and the clinical treatment plan was recalculated on the sCT. The dose distributions from the CT plan and the sCT plan were compared according to a set of dose-volume histogram parameters and gamma evaluation. Treatment techniques included volumetric modulated arc therapy, intensity modulated radiation therapy, and conventional treatment using 2 treatment planning systems and different dose calculation algorithms.

    Results: The overall (multicenter/multivendor) mean dose differences between sCT and CT dose distributions were below 0.3% for all evaluated organs and targets. Gamma evaluation showed a mean pass rate of 99.12% (0.63%, 1 SD) in the complete body volume and 99.97% (0.13%, 1 SD) in the planning target volume using a 2%/ 2-mm global gamma criteria.

    Conclusions: Results of the study show that the sCT conversion method can be used clinically, with minimal differences between sCT and CT dose distributions for target and relevant organs at risk. The small differences seen are consistent between centers, indicating that an MR imagingeonly workflow using MriPlanner is robust for a variety of field strengths, vendors, and treatment techniques.

    A characterization of panconnected graphs satisfying a local ore-type condition1996In: Journal of Graph Theory, ISSN 0364-9024, E-ISSN 1097-0118, Vol. 22, no 2, 95-103 p.Article in journal (Refereed)
    Abstract [en]

    It is well known that a graph G of order p ≥ 3 is Hamilton-connected if d(u) + d(v) ≥ p + 1 for each pair of nonadjacent vertices u and v. In this paper we consider connected graphs G of order at least 3 for which d(u) + d(v) ≥ |N(u) ∪ N(v) ∪ N(w)| + 1 for any path uwv with uv ∉ E(G), where N(x) denote the neighborhood of a vertex x. We prove that a graph G satisfying this condition has the following properties: (a) For each pair of nonadjacent vertices x, y of G and for each integer k, d(x, y) ≤ k ≤ |V(G)| − 1, there is an x − y path of length k. (b) For each edge xy of G and for each integer k (excepting maybe one k η 3,4) there is a cycle of length k containing xy.Consequently G is panconnected (and also edge pancyclic) if and only if each edge of G belongs to a triangle and a quadrangle.Our results imply some results of Williamson, Faudree, and Schelp. © 1996 John Wiley & Sons, Inc.

    A revised geochronology of Thurston Island, West Antarctica, and correlations along the proto-Pacific margin of Gondwana.2017In: Antarctic Science, ISSN 0954-1020, E-ISSN 1365-2079, Vol. 29, 47-60 p.Article in journal (Refereed)
    Abstract [en]

    The continental margin of Gondwana preserves a record of long-lived magmatism from the Andean Cordillera to Australia. The crustal blocks of West Antarctica form part of this margin, with Palaeozoic–Mesozoic magmatism particularly well preserved in the Antarctic Peninsula and Marie Byrd Land. Magmatic events on the intervening Thurston Island crustal block are poorly defined, which has hindered accurate correlations along the margin. Six samples are dated here using U-Pb geochronology and cover the geological history on Thurston Island. The basement gneisses from Morgan Inlet have a protolith age of 349±2 Ma and correlate closely with the Devonian–Carboniferous magmatism of Marie Byrd Land and New Zealand. Triassic (240–220 Ma) magmatism is identified at two sites on Thurston Island, with Hf isotopes indicating magma extraction from Mesoproterozoic-age lower crust. Several sites on Thurston Island preserve rhyolitic tuffs that have been dated at 182 Ma and are likely to correlate with the successions in the Antarctic Peninsula, particularly given the pre-break-up position of the Thurston Island crustal block. Silicic volcanism was widespread in Patagonia and the Antarctic Peninsula at ~ 183 Ma forming the extensive Chon Aike Province. The most extensive episode of magmatism along the active margin took place during the mid-Cretaceous. This Cordillera ‘flare-up’ event of the Gondwana margin is also developed on Thurston Island with granitoid magmatism dated in the interval 110–100 Ma.

    Early Jurassic magmatism on the Antarctic Peninsula and potential correlation with the Subcordilleran plutonic belt of Patagonia.2017In: Journal of the Geological Society, ISSN 0016-7649, E-ISSN 2041-479X, Vol. 174, 365-376 p.Article in journal (Refereed)
    Abstract [en]

    Early Jurassic silicic volcanic rocks of the Chon Aike Province (V1: 187 – 182 Ma) are 30 recognised from many localities in the southern Antarctic Peninsula and northeast Patagonia and are 31 essentially coeval with the extensive Karoo (182 Ma) and Ferrar (183 Ma) large igneous provinces of 32 pre-breakup Gondwana. Until recently, plutonic rocks of this age were considered either rare or 33 absent from the Antarctic Peninsula batholith, which was thought to have been mainly constructed 34 during the Middle Jurassic and the mid-Cretaceous. New U-Pb zircon geochronology from the 35 Antarctic Peninsula and recently published U-Pb ages from elsewhere on the Peninsula and 36 Patagonia are used to demonstrate the more widespread nature of Early Jurassic plutonism. Eight 37 samples are dated here from the central and southern Antarctic Peninsula. They are all moderately 38 to strongly foliated granitoids (tonalite, granite, granodiorite) and locally represent the crystalline 39 basement. They yield ages in the range 188 – 181 Ma, and overlap with published ages of 185 – 180 40 Ma from granitoids from elsewhere on the Antarctic Peninsula and from the Subcordilleran plutonic 41 belt of Patagonia (185 – 181 Ma). Whilst Early Jurassic plutons of the Subcordilleran plutonic belt of 42 Patagonia are directly related to subduction processes along the proto-Pacific margin of Gondwana, 43 coeval volcanic rocks of the Chon Aike Province are interpreted to be directly associated with 44 extension and plume activity during the initial stages of Gondwana break-up. This indicates that 45 subduction was ongoing when Chon Aike Province volcanism started. The Early Jurassic plutonism on 46 the Antarctic Peninsula is transitional between subduction-related and break-up related 47 magamatism.

    To communicate the theory of evolution to all from babies to adults2017In: Conexão Ciencia, ISSN 1980-7058, Vol. 12, no 2, 408-415 p.Article in journal (Refereed)
    Abstract [en]

    Teaching evolution is a tricky business. Less teaching seems to give better understanding of the theory. Evolutionary processes are dialectic relations between many actors, individuals, groups, abiotic and biotic factors etc., different from mechanistic descriptions of relations between singular objects in other scientific theories. This difference, in combination with religious beliefs confuses efforts to get understanding and acceptance of the theory of evolution. With the new curriculum for Swedish compulsory school, science education has to be linked to students’ own experiences in order to promote critical thinking and skills useable in daily life. Further, biology in science teaching during the first school years is focused on general observations and fundamental concepts, not on scientific methods and evolutionary processes. Thus, students often experience biology as a subject filled with facts about simple relations and teleological explanations, making the theory of evolution superfluous. The objectives here were to design teaching in evolutionary theory adapted to the professional needs of students and to assess the learning outcome. Three different courses in evolutionary theory were included. Two pre-service teacher training programs, for nursery school and for year 4–6 in the compulsory school, and one for students in environmental studies were included. Assessments of learning outcome were made by analyses of texts written by the students. The quality of the science knowledge content and the personal and professional development were assessed by using the 4 R’s of Doll. Associations between concepts and understanding were evaluated using clustering and ordination statistical techniques. The learning outcome was good showing visible progressions in the understanding. Thus, it is important to assess the understanding of concepts rather than estimating their frequency in students texts.

    Digestion as an example of integrated teaching of chemistry and biology2017In: Conexão Ciencia, ISSN 1980-7058, Vol. 12, no 2, 89-95 p.Article in journal (Refereed)
    Abstract [en]

    Most people are uncertain about how nutrients enter and are distributed in the body. They may be capable of naming the different parts of the digestive system on a torso but have vague ideas of the relation between these organs and the chemical processes they govern. Reasons for this are poor understanding of gas exchange, the role of the circulatory system, and that most processes are intracellular. In order to create a more holistic view of the biology and chemistry of digestion these subjects may be taught simultaneously and integrated. Here practical exercises and lectures about digestion and nutrients for pre-service primary school teachers are presented. The practical work included food preparation in order to investigate the change of the properties of the macromolecules of nutrients. A simple drawing of a body was used in order to visualize the routes of nutrients and the role of gas exchange in digestion. An evolutionary perspective on digestion was used in order to explain the ancient origin of most chemical processes in the digestive system and in the whole body. The material produced by the students at their final examinations was used for assessing their use and understanding of concepts, the quality based on Doll’s 4R’s and the degree of holistic understanding of the digestive system. The findings show that the pedagogic design used gives a general picture of digestion and energy transfer usable for teaching in primary school.

    Pushing the limits of neutron tomography in palaeontology: Three-dimensional modelling of in situ resin within fossil plants2017In: Palaeontologia Electronica, ISSN 1935-3952, E-ISSN 1094-8074, Vol. 20, no 3.57A, 1-12 p.Article in journal (Refereed)
    Abstract [en]

    Computed tomography is an increasingly popular technique for the non-destructive

    study of fossils. Whilst the science of X-ray computed tomography (CT) has greatly

    matured since its first fossil applications in the early 1980s, the applications and limitations

    of neutron tomography (NT) remain relatively unexplored in palaeontology. These

    highest resolution neutron tomographic scans in palaeontology to date were conducted

    on a specimen of Austrosequoia novae-zeelandiae (Ettingshausen) Mays and Cantrill

    recovered from mid-Cretaceous (Cenomanian; ~100–94 Ma) strata of the Chatham

    Islands, eastern Zealandia. Previously, the species has been identified with in situ fossil

    resin (amber); the new neutron tomographic analyses demonstrated an anomalously

    high neutron attenuation signal for fossil resin. The resulting data provided a

    strong contrast between, and distinct three-dimensional representations of the: 1) fossil

    resin; 2) coalified plant matter; and 3) sedimentary matrix. These data facilitated an

    anatomical model of endogenous resin bodies within the cone axis and bract-scale

    complexes. The types and distributions of resin bodies support a close alliance with

    Sequoia Endlicher (Cupressaceae), a group of conifers whose extant members are

    only found in the Northern Hemisphere. This study demonstrates the feasibility of NT

    as a means to differentiate chemically distinct organic compounds within fossils.

    Herein, we make specific recommendations regarding: 1) the suitability of fossil preservation

    styles for NT; 2) the conservation of organic specimens with hydrogenous consolidants

    and adhesives; and 3) the application of emerging methods (e.g., neutron

    phase contrast) for further improvements when imaging fine-detailed anatomical structures.

    These findings demonstrate that we are still far from reaching the conceptual

    limits of NT as a means of virtually extracting fossils, or imaging their internal anatomy

    even when embedded within a rock matrix.

    Episodic river flooding events revealed by palynological assemblages inJurassic deposits of the Brent Group, North Sea2017In: Palaeogeography, Palaeoclimatology, Palaeoecology, ISSN 0031-0182, E-ISSN 1872-616X, Vol. 485, 389-400 p.Article in journal (Refereed)
    Abstract [en]

    Spore and pollen (sporomorph) assemblages from Middle Jurassic marine deposits of the Brent Group in the northern North Sea are investigated to assess temporal and spatial variations in vegetation and depositional processes. Four wells were sampled for palynology from the Penguins Cluster and the Don North East fields through the Rannoch Formation shoreface succession. Hyperpycnite deposits occur throughout, but are concentrated within the lower part of the section. These are expressed by sand-prone beds displaying waxing and waning current motifs, normally graded muddy beds and structureless mudstones. Hyperpycnal/hypopycnal deposits resulting from episodic river flooding represent important sedimentary features as they may be preserved below fair weather wave base in more offshore settings and potentially be the only record of the former presence of a nearby river mouth. The hyperpycnites typically contain abundant Botryoccocus spp., Amorphous Organic Matter (AOM) and hinterland sporomorph taxa with relatively few marine components compared to associated marine shoreface facies. Variations in palynofacies assemblages and Botryococcus spp. abundances indicate frequent river mouth avulsion. Ordination of samples using non-metric multidimensional scaling (NMDS) indicates that shoreface samples of the sampled wells are relatively distinct, but hyperpycnite samples are highly similar regardless of their sampled well. This suggests that depositional processes and spore/pollen sources (i.e. catchment zones) were similar among hyperpycnite events across different wells. Abundant bisaccate pollen, Botryococcus spp. and AOM within interpreted hyperpycnites suggest sediment mixing along the fluvial drainage path during flooding events. The terrestrial signature of hyperpycnite sporomorph assemblages demonstrates that underflows remained coherent as they descended the shoreface profile with little turbulent mixing with ambient marine waters. Sporomorph assemblages display few large changes through time suggesting vegetation on the adjacent coastal plain was relatively static through the studied interval.

    Mapping of Surface-Exposed Epitopes of In Vitro and In Vivo Aggregated Species of Alpha-Synuclein2017In: Cellular and molecular neurobiology, ISSN 0272-4340, E-ISSN 1573-6830, Vol. 37, no 7, 1217-1226 p.Article in journal (Refereed)
    Abstract [en]

    Aggregated alpha-synuclein is the main component of Lewy bodies, intraneuronal deposits observed in Parkinson's disease and dementia with Lewy bodies. The objective of the study was to identify surface-exposed epitopes of alpha-synuclein in vitro and in vivo formed aggregates. Polyclonal immunoglobulin Y antibodies were raised against short linear peptides of the alpha-synuclein molecule. An epitope in the N-terminal region (1-10) and all C-terminal epitopes (90-140) were found to be exposed in an indirect enzyme-linked immunosorbent assay (ELISA) using recombinant monomeric, oligomeric, and fibrillar alpha-synuclein. In a phospholipid ELISA, the N-terminus and mid-region of alpha-synuclein (i.e., 1-90) were associated with phosphatidylserine and thus occluded from antibody binding. The antibodies that reacted most strongly with epitopes in the in vitro aggregates (i.e., 1-10 and epitopes between positions 90-140) also labeled alpha-synuclein inclusions in brains from transgenic (Thy-1)-h[A30P] alpha-synuclein mice and Lewy bodies and Lewy neurites in brains of patients with alpha-synucleinopathies. However, differences in reactivity were observed with the C-terminal antibodies when brain tissue from human and transgenic mice was compared. Taken together, the study shows that although similar epitopes are exposed in both in vitro and in vivo formed alpha-synuclein inclusions, structural heterogeneity can be observed between different molecular species.

    Att undervisa om juridiska begrepp - pedagogiska utmaningar och tänkbara strategier2017In: Juridisk Publikation, ISSN 2000-2920, no 2, 429-450 p.Article in journal (Refereed)
    Abstract [sv]

    Ämnesdidaktiska frågor inom juristutbildningen har den senaste tiden tilldragit sig ett ökat intresse. I den här artikeln diskuterar jag en fråga som ständigt är aktuell för universitetslärare, nämligen den pedagogiska utmaningen i att undervisa om begrepp. Framställningen tar avstamp i en förhållandevis allmängiltig pedagogisk teori (socialkonstruktionism). Utifrån denna teori diskuteras utmaningen att göra juridiska begrepp begripliga i undervisningssammanhang. För att göra diskussionen gripbar, utgår jag från det straffrättsliga begreppet gärningsculpa, som många juriststudenter stöter på under straffrättskursen. Detta kan naturligtvis bytas ut mot vilket juridiskt begrepp som helst, varför artikeln kan vara givande även för den som undervisar inom andra rättsområden. De tankar som kommer till uttryck i artikeln bygger såväl på rön i högskolepedagogisk litteratur som på mina egna undervisningserfarenheter.

    Att låta det oväntade ge rum åt det oförväntade: Möjligheter inom ramen för skolämnet samhällskunskap2017In: Nordidactica: Journal of Humanities and Social Science Education, ISSN 2000-9879, no 2, 25-43 p.Article in journal (Refereed)
    Abstract [en]

    The aim of the article is to illuminate the opportunities for students in social studies to develop dispositions towards taking an active and responsible role in society when teachers are able to support the content of the subject to continuously come forward in an interactive, communicative and evolving process. Based on theoretical informed arguments the author claims that that the question of how the teaching process is carried out is deeply connected with these opportunities for creating meaningful pedagogical situations. Here, unforeseen events are discussed as desirable circumstances for engaging students in social issues. However, this also brings risk into the process since the content discussed and how it is discussed opens up for unexpected answers. These answers which become part of the course content, put the teacher in a position in which he or she needs to respond in one way or another. In such pedagogical situations, the moral dimension of teachers’ work becomes visible and obvious. The position is taken that risk is a crucial part of a teaching process in which one of the aims is for students to be and become active, responsible and engaged in social issues.

    CD44v6-Targeted Imaging of Head and Neck Squamous Cell Carcinoma: Antibody-Based Approaches2017In: Contrast Media & Molecular Imaging, ISSN 1555-4309, E-ISSN 1555-4317, Vol. 2017, 2709547Article, review/survey (Refereed)
    Abstract [en]

    Head and neck squamous cell carcinoma (HNSCC) is a common and severe cancer with low survival rate in advanced stages. Noninvasive imaging of prognostic and therapeutic biomarkers could provide valuable information for planning and monitoring of the different therapy options. Thus, there is amajor interest in development of new tracers towards cancer-specific molecular targets to improve diagnostic imaging and treatment. CD44v6, an oncogenic variant of the cell surface molecule CD44, is a promising molecular target since it exhibits a unique expression pattern in HNSCC and is associated with drug-and radio-resistance.

    In this review we summarize results from preclinical and clinical investigations of radiolabeled anti-CD44v6 antibody-based tracers: full-length antibodies, Fab, F(ab')(2) fragments, and scFvs with particular focus on the engineering of various antibody formats and choice of radiolabel for the use as molecular imaging agents in HNSCC. We conclude that the current evidence points to CD44v6 imaging being a promising approach for providing more specific and sensitive diagnostic tools, leading to customized treatment decisions and functional diagnosis. Improved imaging tools hold promise to enable more effective treatment for head and neck cancer patients.

    Automatic Characterization of the Physiological Condition of the Carotid Artery in 2D Ultrasound Image Sequences Using Spatiotemporal and Spatiospectral 2D Maps.2014In: International Journal of Biomedical Imaging, ISSN 1687-4188, E-ISSN 1687-4196, Vol. 2014, 876267Article in journal (Refereed)
    Abstract [en]

    A novel method for characterizing and visualizing the progression of waves along the walls of the carotid artery is presented. The new approach is noninvasive and able to simultaneously capture the spatial and the temporal propagation of wavy patterns along the walls of the carotid artery in a completely automated manner. Spatiotemporal and spatiospectral 2D maps describing these patterns (in both the spatial and the frequency domains, resp.) were generated and analyzed by visual inspection as well as automatic feature extraction and classification. Three categories of cases were considered: pathological elderly, healthy elderly, and healthy young cases. Automatic differentiation, between cases of these three categories, was achieved with a sensitivity of 97.1% and a specificity of 74.5%. Two features were proposed and computed to measure the homogeneity of the spatiospectral 2D map which presents the spectral characteristics of the carotid artery wall's wavy motion pattern which are related to the physical, mechanical (e.g., elasticity), and physiological properties and conditions along the artery. These results are promising and confirm the potential of the proposed method in providing useful information which can help in revealing the physiological condition of the cardiovascular system.

  • Setting the stage for a sustainable food future: Seven takeaways from Nordic Food Day at COP232017Other (Other (popular science, discussion, etc.))
    Abstract [en]

    How can the Nordic countries address pressing global challenges like food waste, unsustainable diets and the loss of biodiversity? This very question was the starting point for Nordic Food Day on the 9th of November. The Nordic Pavilion at COP23 was transformed into a pop-up think tank, bringing representatives from leading organizations and institutions, together to discuss how to put food policy on the climate agenda. The thematic day, Nordic Food Day, was the kick-off of the Nordic Food Policy Lab. www.norden.org/nordicfoodday

    The Right of Access to Information and the Right to Privacy: A Democratic Balancing Act2017Collection (editor) (Other academic)
    Abstract [en]

    This publication gathers presentations from an international and trans-disciplinary workshop held at Södertörn University in December 2016.

    The workshop entitled The Right of Access to Information and the Right to Privacy: A Democratic Balancing Act was one of the many events which celebrated the 250th anniversary of the Swedish Freedom of the Press Act, the first legal instrument in the world laying down the right of access to official documents. A starting point for the workshop was the assumption that the right of access to information and the right to privacy are both necessary pre-conditions for a democratic society. Researchers from a broad range of fields were invited to discuss how these assumptions should be examined, and how the balance between the two interests should be assessed when conflicting with each other. The objective of the workshop was to broaden our understanding of various national and disciplinary approaches to the democratic balance between the right of access and the right to privacy.

    Among the conclusions we may draw from the workshop, and the articles emanating from it, is the confirmation of the need to strike the balance between the right of access and the right to privacy. This is certainly difficult, but since the two interests are both of such importance for democracy, we constantly need to make the effort. The articles in this volume contain information on some of the areas that need our further attention.

    Seismic evidence for complex sedimentary control of Greenland Ice Sheet flow2017In: Science Advances, ISSN 0036-8156, E-ISSN 2375-2548, Vol. 3, no 8, e1603071Article in journal (Refereed)
    Abstract [en]

    The land-terminating margin of the Greenland Ice Sheet has slowed down in recent decades, although the causes and implications for future ice flow are unclear. Explained originally by a self-regulating mechanism where basal slip reduces as drainage evolves from low to high efficiency, recent numerical modeling invokes a sedimentary control of ice sheet flow as an alternative hypothesis. Although both hypotheses can explain the recent slowdown, their respective forecasts of a long-term deceleration versus an acceleration of ice flow are contradictory. We present amplitude-versus-angle seismic data as the first observational test of the alternative hypothesis. We document transient modifications of basal sediment strengths by rapid subglacial drainages of supraglacial lakes, the primary current control on summer ice sheet flow according to our numerical model. Our observations agree with simulations of initial postdrainage sediment weakening and ice flow accelerations, and subsequent sediment restrengthening and ice flow decelerations, and thus confirm the alternative hypothesis. Although simulated melt season acceleration of ice flow due to weakening of subglacial sediments does not currently outweigh winter slowdown forced by self regulation, they could dominate over the longer term. Subglacial sediments beneath the Greenland Ice Sheet must therefore be mapped and characterized, and a sedimentary control of ice flow must be evaluated against competing self-regulation mechanisms.

  • Youth, democracy, and democratic exclusion in the Nordic countries2017Other (Other (popular science, discussion, etc.))
    Abstract [en]

    Young people in the Nordic countries participate less in elections than the overall population. The turnout is lowest among youth in their early twenties. Meanwhile, Nordic youth have high rates of participation when it comes to other forms of democratic participation. Certain groups of Nordic youth in particular have low turnouts. Youth with non-western or Eastern European immigrant background, with low levels of education, low income, that have parents with low educational levels, and who are children of non-voters have strikingly lower turnouts.Several successful and partly successful measures to increase youth turnout have been carried out in the Nordic countries. It is essential that Nordic politicians and policymakers prioritise the work towards increasing the turnout of youth. If not, we may risk the permanent de facto exclusion from democracy of certain groups.

    Investigation on Interval Edge-Colorings of Graphs1994In: Journal of combinatorial theory. Series B (Print), ISSN 0095-8956, E-ISSN 1096-0902, Vol. 62, no 1, 34-43 p.Article in journal (Other academic)
    Abstract [en]

    An edge-coloring of a simple graph G with colors 1, 2,..., t is called an interval t-coloring [3] if at least one edge of G is colored by color i, i = 1, ..., t and the edges incident with each vertex x are colored by dG(x) consecutive colors, where dG(x) is the degree of the vertex x. In this paper we investigate some properties of interval colorings and their variations. It is proved, in particular, that if a simple graph G = (V, E) without triangles has an interval t-coloring, then t ≤ |V| − 1.

    Interplanetary coronal mass ejection observed at STEREO-A, Mars, comet 67P/Churyumov-Gerasimenko, Saturn, and New Horizons en route to Pluto: Comparison of its Forbush decreases at 1.4, 3.1, and 9.9 AU2017In: Journal of Geophysical Research - Space Physics, ISSN 2169-9380, E-ISSN 2169-9402, Vol. 122, no 8, 7865-7890 p.Article in journal (Refereed)
    Abstract [en]

    We discuss observations of the journey throughout the Solar System of a large interplanetary coronal mass ejection (ICME) that was ejected at the Sun on 14 October 2014. The ICME hit Mars on 17 October, as observed by the Mars Express, Mars Atmosphere and Volatile EvolutioN Mission (MAVEN), Mars Odyssey, and Mars Science Laboratory (MSL) missions, 44h before the encounter of the planet with the Siding-Spring comet, for which the space weather context is provided. It reached comet 67P/Churyumov-Gerasimenko, which was perfectly aligned with the Sun and Mars at 3.1 AU, as observed by Rosetta on 22 October. The ICME was also detected by STEREO-A on 16 October at 1 AU, and by Cassini in the solar wind around Saturn on the 12 November at 9.9AU. Fortuitously, the New Horizons spacecraft was also aligned with the direction of the ICME at 31.6 AU. We investigate whether this ICME has a nonambiguous signature at New Horizons. A potential detection of this ICME by Voyager 2 at 110-111 AU is also discussed. The multispacecraft observations allow the derivation of certain properties of the ICME, such as its large angular extension of at least 116 degrees, its speed as a function of distance, and its magnetic field structure at four locations from 1 to 10 AU. Observations of the speed data allow two different solar wind propagation models to be validated. Finally, we compare the Forbush decreases (transient decreases followed by gradual recoveries in the galactic cosmic ray intensity) due to the passage of this ICME at Mars, comet 67P, and Saturn.

    The External Validity of Mapping MSIS-29 on EQ-5D Among Individuals With Multiple Sclerosis in Sweden2017In: Medical Decision Making Policy & Practice, ISSN 2381-4683, Vol. 2, no 1Article in journal (Refereed)
    Abstract [en]

    Background: Mapping can be performed to predict utility values from condition-specific measures when preference-based measures are absent. A previously developed algorithm that predicts EQ-5D-3L index values from the Multiple Sclerosis Impact Scale (MSIS-29) has not yet been externally validated. Aim: To examine the external validity of a previously developed mapping algorithm by testing the accuracy of predicting EQ-5D-3L index values from MSIS-29 among multiple sclerosis (MS) patients in Sweden. Methods: Cross-sectional individual-level data were collected from population-based Swedish registers between 2011 and 2014. Health-related quality of life was assessed through MSIS-29 and EQ-5D-3L at one point in time among 767 individuals with known disability level of MS. A previously developed mapping algorithm was applied to predict EQ-5D index values from MSIS-29 items, and the predictive accuracy was assessed through mean absolute error and root mean square error. Results: When applying the algorithm, the predicted mean EQ-5D-3L index value was 0.77 compared to the observed mean index value of 0.75. Prediction error was higher for individuals reporting EQ-5D values <0.5 compared to individuals reporting EQ-5D values ≥0.5. Mean absolute error (0.12) and root mean square error (0.18) were smaller or equal to the prediction errors found in the original mapping study. Conclusion: The mapping algorithm had similar predictive accuracy in the two independent samples although results showed that the highest predictive performance was found in groups with better health. Varied predictive accuracy in subgroups is consistent with previous studies and strategies to deal with this are warranted.

    Processing of self-reinforced poly(ethylene terephthalate) composites for automotive applications2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The vehicles of the future must have less negative environmental impact during their use phase than the vehicles of today in order to avoid major climate change on earth. Consequently electric vehicles are currently under development with the purpose of reducing CO2 emissions when the vehicle is

    driven. There are also efforts put in to reducing the weight of vehicles in order to reduce the demand for energy to drive them. One important aspect of weight reduction is that new materials and technologies are developed. Plastic materials have low a density and can therefore be used to reduce the weight of vehicle components and with composite materials there is further potential for weight reduction. Self-reinforced thermoplastic composite materials are materials in which both reinforcement and matrix are thermoplastic materials and thanks to their low density and relatively good mechanical properties, these materials may be used for weight reduction of vehicle components.

     

    The aim of this thesis is to study selected process parameters for component manufacturing with self-reinforced poly(ethylene terephthalate) (SrPET) in order to increase knowledge and thereby advance the field of self-reinforced PET composites. This thesis shows that stretching the material in the manufacturing process increases the mechanical performance of the material due to increased orientation of the amorphous phase in the PET reinforcement. However, stretching introduces stresses in the material that give rise to negative shape distortions in the formed component. The degree of stretching during forming must therefore be controlled in order to achieve a robust serial production. The concept of a SrPET component over-moulded for integration of stiffeners and attachments has been evaluated in a life-cycle-assessment. This evaluation shows that the component weight can be reduced compared to technology currently in use and thereby contribute to increased sustainability of transport.

    Modellering av järnvägstransporter: en översikt kring datakällor2017Report (Other academic)
    Abstract [en]

    Information on freight and passenger flows is vital for advancing knowledge on railway transport. In addition to providing a description of the current use of railway transportation, the flows of freight and passengers can be used in transport models to make transportation forecasts. Such forecasts can, for example, be used to evaluate infrastructure investments, or to analyze the impact of new restrictions or new policies. The transport statistics in Sweden are, however, quite aggregate, which makes forecasts and other types of estimations rather uncertain. There is therefore reason to describe the current modelling of railway transport, as well as its development and potential in combining different (and new) data sources to provide the information on railway transport that is requested.

    Sampers and Samgods are the national models in Sweden for freight and passenger transports, respectively. Three types of data are used in Sampers: data describing travel behavior, information about the transport network and public transport services, as well as attraction measures for trips to the different geographical zones in the model. The output from the demand model are passenger flows for each transport mode and destination. Train passengers are distributed on the railway network based on current traffic flows, while anticipated timetables are used in the forecasts. This generates information on the number of trips for each railway link during a year (that is, between stations or nodes on railway lines), as well as the number of embarking and disembarking passengers on the railway stations. These results need validation, which inter alia is performed by regions within the Swedish Transport Administration, using passenger statistics.

    Data inputs for Samgods are information on the transport network, cost data, regulations, production and consumption data and goods flows. The data on goods flows are gathered from foreign trade statistics and the national commodity flow survey. The production and consumption data are used together with the goods flows data to calculate the transported volume of 34 different commodity types between 464 zones (of which 290 are municipalities in Sweden). A separate tool called Bangods is used to generate rail freight transport on the different track sections comprising the railway network. This is based on rail traffic data, which however lacks information on the type of freight trains as well as commodity type and volume of goods per train. At present, the output for rail freight transport consists of goods flows during a year on the different track sections (about 300), segmented into different types of freight trains and 12 groups of commodities.

    Transport modelling approaches are becoming more disaggregate. More specifically, there is a development towards activity-based models for passenger transport, while modelling of logistic choices at company level is becoming more common for freight transport. This development requires more disaggregate data, in both time and space. The rapid technological development has provided new opportunities in collecting disaggregate data, notably through low prices and improved performance of the technical units required to record and communicate information on the positioning of people, goods or vehicles. Examples on data sources are data from radionavigation-satellite services (Global Positioning System, GPS), cell phone data, Radio Frequency Identification (RFID) or other types of sensors (for train weight or number of embarking and disembarking passengers).

    There are pros and cons with these different data sources in transport modelling; one type of data source cannot cover the information needs. A combination of data can therefore be a solution. For example, GPS data and cell phone data can be good complements, as the former have a higher level of detail while the latter have larger blind spots. Still, a general problem with the automatic collection of data is that only a sub-sample of the trips are captured; even though it generates more detailed information on the position and timing of trips compared to traditional travel surveys, it is still based on a sub-sample of the trips made, which can create a selection bias. Moreover, this type of data lacks information on socio-economic aspects and the purpose of the trip. However, information on work and home location can be derived from mobility patterns based on GPS or cell phone data, which in turn can be linked to socio-economic information (at least at an aggregate level). Nevertheless, information on passenger and freight flows can be useful in the calibration and validation of the transport models. For instance, train payload measurements can be used to derive information on the number of passengers on each train (potentially between all stations if the train has a weighing capability, or if enough stationary weight detectors are installed on the infrastructure). Moreover, even though the weight of a freight train does not reveal the commodity type, it can be used in the calibration of Samgods and provide a more accurate flow of goods on different trains and track sections. In other words, new technology and data collection methods provide a significant potential for generating more disaggregate data on transport flows.

    Abstract [en]

    This study analyses the content of the International Journal of Wine Business Research (IJWBR) and gives editors, reviewers, authors and practitioners an overview over the journal’s development over 26 years. The articles published in the journal since its inception in 1989 till 2014, inclusive, were analyzed in two time frames. The first time frame covers 1989 to 2006 as the International Journal of Wine Marketing (IJWM), while the second time frame covers 2007 to 2014 as IJWBR, the new name under which the journal re-launched. All types of articles are included in the analysis with the exception of editorials, guest editorials and research notes. Five main themes are addressed: the nature of authorship, the most prolific and influential authors, characteristics of the manuscripts, regional distribution of the wine’s region-of-origin and focal markets, and the most common research themes.

     

    The content analysis of this journal sheds light on how the style of the journal has evolved since its inception in 1989 onto the second time frame. The types of articles and methods used have been consistent in the early issues (1989-2006). However, since 2007 the journal has welcomed more academic and quantitative articles. The change motivated new authors to write longer articles, collaborate more, use more references, tables and figures. As a result, the journal’s impact has increased significantly. In addition, empirical studies published in the journal indicated an increase in the publications covering the Americas as both regions of origin and focal markets, as compared to other regions. This is the first time a content analysis has been carried out for IJWBR. The objective is to help authors identifying new and interesting research areas as well as to give editors and reviewers insight into the style and areas explored since the journal’s inception. By using software tools for data collection and analysis, the study is bound to the limitations inherent from these tools.
