Konferensbidrag (refereegranskat)abstract
- Abstract in UndeterminedThe importance of computer learner corpora for research in both second language acquisition and foreign language teaching is rapidly increasing. Computer learner corpora can provide us with data to describe the learner's interlanguage system at different points of its development and they can be used to create pedagogical tools.In this paper, we first present a new computer learner corpora in French. We then describe an analyzer called Direkt Profil, that we have developed using this corpus. The system carries out a sentence analysis based on developmental sequences, i.e. local morphosyntactic phenomena linked to a development in the acquisition of French as a foreign language. We present a brief introduction to developmental sequences and some examples in French. In the final section, we introduce and evaluate a method to optimize the definition and detection of learner profiles using machine-learning techniques.

A Comparison of Pointwise and Levelling Assisted Regional Realisations of IHRS with a Case Study over Sweden
- 2023
-
Ingår i: International Association of Geodesy Symposia. - : Springer Berlin/Heidelberg. ; , s. 3-9
-
Bokkapitel (refereegranskat)abstract
- The International Height Reference System (IHRS) was defined by the International Association of Geodesy (IAG) in 2015. The global International Height Reference Frame (IHRF) should provide access to the IHRS in a broad sense. To provide high accuracy local access, regional (or national) realisations will also be needed. This study aims at evaluating different approaches to compute a denser regional realisation of IHRS in case a high accuracy levelling network is available. Using Sweden as a case study region, a GNSS (Global Navigation Satellite System) and geoid based pointwise realisation is compared with three types of levelling assisted realisations. The latter are made by applying least squares adjustments of the precise levelling observations with fixed potential value(s) from either the global IHRF station in Sweden or the pointwise potentials of a larger number of stations. It is concluded that making a minimum constraint adjustment with one station fixed is not the best option. It is favourable to fix a reasonable number of pointwise stations at an internal distance over which the relative uncertainty of levelling is significantly lower than the relative uncertainty of the pointwise solution. The investigation is made using levelling data from the third precise levelling of Sweden, the NKG2015 quasigeoid model and the NKG2016LU postglacial land uplift model.

A first step towards a national realisation of the international height reference system in Sweden with a comparison to RH 2000
- 2023

Ingår i: Journal of Geodetic Science. - : de Gruyter. - 2081-9919 .- 2081-9943. ; 13:1

Tidskriftsartikel (refereegranskat)abstract
- The International Height Reference System (IHRS) was defined by the International Association of Geodesy in 2015. Since then, the international geodetic community has been working on the specification and establishment of its realisation, the International Height Reference Frame (IHRF). This frame will primarily be realised by geopotential numbers (or physical heights) in a sparse global reference network. In Sweden, only one such global station is planned. Regional and national realisations (or densifications) computed in accordance with the IHRS definition are needed to enable the best possible unification of height datums. The main purpose of this article is to make a case study for Sweden regarding the national realisation of IHRS and to investigate in what way preliminary IHRF differs from the current Swedish levelling-based realisation of the European Vertical Reference System, RH 2000. The two different quasigeoid models that we consider best over Sweden at the present time are used to compute the preliminary IHRS realisations in the study. The realisations are compared to each other and to RH 2000. It is shown that a very significant part of the difference to RH 2000 is due to the different postglacial land uplift epochs, permanent tide concepts, and zero levels. The standard deviation for the difference between one of the preliminary national IHRS realisations and RH 2000 is reduced from 75.5 to 19.2 mm after correction of the postglacial land uplift and permanent tide effects. The corresponding mean differences are –208.5 and –454.7 mm, respectively. The magnitude of the mean difference thus increases when the corrections in question are applied.

Regional realisations of IHRS, the International Height Reference System
- 2024
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- A common global vertical reference frame for physical heights is essential in many applications, but an equivalent to the three-dimensional International Terrestrial Reference System has until recently been lacking for physical heights. The International Height Reference System, IHRS, was defined in 2015. It will be realised by the International Height Reference Frame, IHRF, on the global level by a sparse core reference network. To ensure local access and enable optimum height datum unification, adopted regional or national realisations (or densifications) are required. This thesis explores regional and national realisations of IHRS, employing both the standard pointwise methodology as well as levelling assisted approaches. Levelling observations have the potential to improve pointwise IHRS realisations. The thesis studies a regional levelling network that is adjusted with respect to an initial pointwise IHRS realisation using different approaches. The evaluation of these solutions is based on the resulting geopotential numbers and their estimated standard uncertainties. It is shown that including levelling observations in the IHRS realisation process might lead to significant improvements. It is recommended to employ a weighted adjustment of pointwise geopotential numbers and levelling observations, and to utilise variance component estimation as a tool to estimate a priori uncertainties. With a comparison to the Swedish levelling based realisation of the European Vertical Reference System, RH 2000, differences in the definitions of reference systems are explored. Corrections related to known effects, such as permanent tide concepts, postglacial land uplift epoch and zero level, are here considered. It is shown that the differences in the obtained geopotential numbers can be explained to rather large extent by these corrections. Finally, the thesis discusses how national and regional realisations of IHRS should be interpreted with respect to the global realisation.

Undifferenced GPS for Deformation Monitoring
- 2006
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis contains the development of a deformation monitoring software based on undifferenced GPS observations. Software like this can be used in alarm systems placed in areas where the earth is unstable. Systems like this can be used in areas where people are in risk of getting hurt, like in earthquake zones or in land slide areas, but they can also be useful when monitoring the movements in buildings, bridges and other artefacts. The main hypotheses that are tested are whether it is possible to detect deformations with undifferenced observations and if it is possible to reach the same accuracy in this mode as when working in a traditional mode where the observations are differenced. The development of a deformation monitoring software based on undifferenced GPS observations is presented. A complete mathematical model is given as well as implementation details. The software is developed in Matlab together with a GPS observation simulator. The simulator is mainly used for debugging purposes. The developed software is tested with both simulated and real observations. Results from tests with simulated observations show that it is possible to detect deformations in the order of a few millimetres with the software. Calculations with real observations give the same results. Further, the result from calculations in static mode indicates that the commercial software and the undifferenced software diverge a few millimetres, which probably depends on different implementations of the tropospheric corrections. In kinematic mode the standard deviation is about 1 millimetre larger in the undifferenced mode than in the double differenced mode. An initial test with different observation weighting procedures indicates that there is a lot of potential to improve the result by applying correct weights to the observations. This is one of the aims in the future work within this project. This thesis are sponsored by the Swedish Research Council for Enviroment, Agricultural Sciences and Spatial Planning, FORMAS within the framework “Monitoring of construction and detection of movements by GPS ref no. 2002-1257"

Volatility modeling in the presence of measurement errors
- 2001
-
Ingår i: Journal of Risk. - 1465-1211. ; 3:4, s. 53-67
-
Tidskriftsartikel (refereegranskat)abstract
- In this paper, the authors examine the effects of measurement errors on volatility measures. This is done by first expressing the moment properties of general volatility models with measurement errors in terms of the corresponding moments for the underlying unobserved signal process. Then the consequences of measurement errors for some GARCH and stochastic volatility models are evaluated. It is shown that measurement error causes the autocorrelation function, here for the squared process, to start and remain lower than for the underlying unobserved signal process. The size of the effects are highly dependent on the degree of persistence in the volatility. Finally, the consequences of measurement errors on time-varying VaR measures are studied.

Deflection of Vertical Effect on Direct Georeferencing in Aerial Mobile Mapping Systems : A Case Study in Sweden
- 2022

Tidskriftsartikel (refereegranskat)abstract
- GNSS/INS applications are being developed, especially for direct georeferencing in airborne photogrammetry. Achieving accurately georeferenced products from the integration of GNSS and INS requires removing systematic errors in the mobile mapping systems. The INS sensor's uncertainty is decreasing; therefore, the influence of the deflection of verticals (DOV, the angle between the plumb line and normal to the ellipsoid) should be considered in the direct georeferencing. Otherwise, an error is imposed for calculating the exterior orientation parameters of the aerial images and aerial laser scanning. This study determines the DOV using the EGM2008 model and gravity data in Sweden. The impact of the DOVs on horizontal and vertical coordinates, considering different flight altitudes and camera field of view, is assessed. The results confirm that the calculated DOV components using the EGM2008 model are sufficiently accurate for aerial mapping system purposes except for mountainous areas because the topographic signal is not modelled correctly.

Konferensbidrag (refereegranskat)abstract
- Direct georeferencing of airborne mobile mapping systems is developing with unprecedented speed using GNSS/INS integration. Removal of systematic errors is required for achieving a high accurate georeferenced product in mobile mapping platforms with integrated GNSS/INS sensors. It is crucial to consider the deflection of verticals (DOV) in direct georeferencing due to the recently improved INS sensor accuracy. This study determines the DOV using Sweden's EGM2008 model and gravity data. The influence of the DOVs on horizontal and vertical coordinates and considering different flight heights is assessed. The results confirm that the calculated DOV components using the EGM2008 model are sufficiently accurate for aerial photogrammetry purposes except for the mountainous areas because the topographic signal is not modeled correctly.

Physical and Geometric Effects on the Classical Geodetic Observations in Small-Scale Control Networks

Tidskriftsartikel (refereegranskat)abstract
- In classical two-dimensional (2D) geodetic networks, reducing slope distances to horizontal ones is an important task for engineers. These horizontal distances along with horizontal directions are used in 2D geodetic adjustment. The common practice for this reduction is the use of vertical angles to reduce distances using trigonometric rules. However, one faces systematic effects when using vertical angles. These effects are mainly due to refraction, deflection of the vertical (DOV), and the geometric effect of the reference surface (sphere or ellipsoid). To mitigate refraction and DOV effects, one can choose to observe the vertical angles reciprocally if the baseline points’ elevation difference is small. This paper quantifies these effects and proposes a proper solution to eliminate the effects in small-scale geodetic networks (where the longest distances are less than 5 km). The goal is to calculate slope distances into horizontal ones appropriately. For this purpose, we used the SWEN17_RH2000 quasigeoid model (in Sweden) to study the impact of the DOV applying different baseline lengths, azimuths, and vertical angles. Finally, we propose an approach to study the impact of the geometric effect on vertical angles. We illustrate that the DOV and the geometric effects on vertical angles measured reciprocally are significant if the height difference of the start point and endpoint in the baseline is large. Geometric correction should be considered for the measured vertical angles to calculate horizontal distances correctly if the network points are not on the same elevation, even if the vertical angles are measured reciprocally.

Granular superconductor in a honeycomb lattice as a realization of bosonic Dirac material
- 2016

Ingår i: PHYSICAL REVIEW B. - : American Physical Society. - 2469-9950. ; 93:13
-
Tidskriftsartikel (refereegranskat)abstract
- We examine the low-energy effective theory of phase oscillations in a two-dimensional granular superconducting sheet where the grains are arranged in a honeycomb lattice structure. Using the example of graphene, we present evidence for the engineered Dirac nodes in the bosonic excitations: the spectra of the collective bosonic modes cross at the K and K' points in the Brillouin zone and form Dirac nodes. We show how two different types of collective phase oscillations are obtained and that they are analogous to the Leggett and the Bogoliubov-Anderson-Gorkov modes in a two-band superconductor. We show that the Dirac node is preserved in the presence of an intergrain interaction, despite induced changes of the qualitative features of the two collective modes. Finally, breaking the sublattice symmetry by choosing different on-site potentials for the two sublattices leads to a gap opening near the Dirac node, in analogy with fermionic Dirac materials. The Dirac node dispersion of bosonic excitations is thus expanding the discussion of the conventional Dirac cone excitations to the case of bosons. We call this case as a representative of bosonic Dirac materials (BDM), similar to the case of Fermionic Dirac materials extensively discussed in the literature.

Praktiker som gör skillnad : Om den verb-inriktade metoden

Tidskriftsartikel (refereegranskat)abstract
- This article discusses the so-called verb-oriented method and its role in the research project Gender and Work in early modern Sweden (GaW), which is based at Uppsala University. It provides a presentation of the GaW-database, which has been designed to allow analysis according to the verb-method. Finally, the article points out that this method can be combined with a number of different theoretical approaches as long as the focus is on practices. It is therefore compatible with the approaches of e.g., Judith Butler, Michel de Certeau, and Amartya Sen. Work is defined as "time-use with the purpose of making a living" and the article discusses why data on time-use, or actual work activities, are better suited for research into early modern Swedish working life than other types of data. It shows that activities are usually described in the sources by verb-phrases, and explains how and from what sources verb-phrases are collected and analyzed within the project. In order to allow for generalizations the verb-method presupposes large amounts of data. This is the rationale for the GaW-database, which at present includes around 5000 verb-phrases and 75000 data posts.

Disruption of Memory Reconsolidation Erases a Fear Memory Trace in the Human Amygdala : An 18-Month Follow-Up.
- 2015

Ingår i: PLOS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 10:7, s. e0129393-
-
Tidskriftsartikel (refereegranskat)abstract
- Fear memories can be attenuated by reactivation followed by disrupted reconsolidation. Using functional magnetic resonance imaging we recently showed that reactivation and reconsolidation of a conditioned fear memory trace in the basolateral amygdala predicts subsequent fear expression over two days, while reactivation followed by disrupted reconsolidation abolishes the memory trace and suppresses fear. In this follow-up study we demonstrate that the behavioral effect persists over 18 months reflected in superior reacquisition after undisrupted, as compared to disrupted reconsolidation, and that neural activity in the basolateral amygdala representing the initial fear memory predicts return of fear. We conclude that disrupting reconsolidation have long lasting behavioral effects and may permanently erase the fear component of an amygdala-dependent memory.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this work was to evaluate the use of Monte Carlo-based calibrations for in situ gamma-ray spectrometry. We have performed in situ measurements at five different sites in Sweden using HPGe detectors to determine ground deposition activity levels of (137)Cs from the 1986 Chernobyl accident. Monte Carlo-calculated efficiency calibration factors were compared with corresponding values calculated using a more traditional semi-empirical method. In addition, results for the activity ground deposition were also compared with activity densities found in soil samples. In order to facilitate meaningful comparisons between the different types of results, the combined standard uncertainty of in situ measurements was assessed for both calibration methods. Good agreement, both between the two calibration methods, and between in situ measurements and soil samples, was found at all five sites. Uncertainties in in situ measurements for the given measurement conditions, about 20 years after the fallout occurred, were found to be in the range 15-20% (with a coverage factor k=1, i.e. with a confidence interval of about 68%).

Tidskriftsartikel (refereegranskat)abstract
- Semi-empirical methods are often used for efficiency calibrations of in situ gamma-ray spectrometry measurements with high-purity germanium detectors. The intrinsic detector efficiency is experimentally determined for different photon energies and angles of incidence, and a suitable expression for the efficiency is fitted to empirical data. In this work, the combined standard uncertainty of such an efficiency function for two detectors was assessed. The uncertainties in individual efficiency measurements were found to be about 1.9 and 3.1% (with a coverage factor k = 1, i.e. with a confidence interval of about 68%) for the two detectors. The main contributions to these uncertainties were found to originate from uncertainties in source-to-detector distance, source activity and full-energy peak count rate. The standard uncertainties of the fitted functions were found to be somewhat higher than the uncertainty of individual data points, i.e. 5.2 and 8.1% (k = 1). With the introduction of a new expression for the detector efficiency, these uncertainties were reduced to 3.7 and 4.2%, i.e. with up to a factor of two. Note that this work only addresses the uncertainty in the determination of intrinsic detector efficiency.

Bokkapitel (populärvet., debatt m.m.)abstract
- Det här kapitlet fokuserar på att förklara de grundläggande principerna för insamling av geografiska data, och vi lägger tonvikten på fjärranalys och geodetiska metoder. Fjärranalys innefattar olika tekniker som fotogrammetri, laserskanning och analys av bilder från mark, flyg och satelliter. Geodetiska datainsamling används för att mäta in koordinater för objekt på marken och innefattar satellitbaserade tekniker såväl som användning av fältinstrument. Olika tekniker, avseende både fjärranalys och geodesi, används i olika situationer beroende på krav på noggrannhet och innehåll, och kompletterar därför varandra. Vi börjar med att beskriva satellitfjärranalys som kan täcka stora områden med relativt begränsad detaljeringsgrad, beskriver sedan flygbilder och laserskanning där detaljnivån ökar, för att till sist beskriva de geodetiska metoderna för noggranna mätningar på marknivå.

Tidskriftsartikel (refereegranskat)abstract
- The increased need for improved geoid models for Global Navigation Satellite Systems (GNSS) height determination calls for additional gravity observations and quality assurance of existing data. In this perspective, a modern gravity system and the renovation of an already existing high order gravity network is considered as a moderate strategic investment which provides a firm foundation for further activities. Here the new gravity reference frame RG 2000 for Sweden is presented. RG 2000 is realized by absolute gravity observations at 109 stations. The absolute points are connected via old and new relative gravity observations, including another 216 points. Points and observations have been chosen so that good overlap with the older Swedish reference frames, RG 62 and RG 82, is achieved, allowing to evaluate the older frames and transformations between them. RG 2000 is based on a zero permanent tide system with epoch 2000.

Tidskriftsartikel (refereegranskat)abstract
- While gender relations in the post-1800 labour market have been subject to much scholarly scrutiny, less is known about how women and men supported themselves in the early modern period. This article discusses the reasons for this lacuna and explores various approaches that could be used to increase knowledge in the field. It describes the verb-oriented method, used by the Gender and Work project at Uppsala University and inspired by the work of Sheilagh Ogilvie. Understanding ‘work’ as ‘use of time with the goal of making a living’, the method consists in systematic collection of verb phrases such as ‘to fish herring’, ‘to sell clothes’, etc. The article also presents the database GaW, which is designed so as to make possible systematic analysis of large sets of verb phrases.

RAPPORT GEODATARÅDETS HANDLINGSPLAN 2020 : Aktivitet – 4i, Långsiktig kompetensförsörjning inom geodataområdet
- 2020
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- I den nationella geodatastrategin som gäller för åren 2016–2020 återfinns målet ”Samverkan är välutvecklad” (mål nummer 4). Inom ramen för detta mål ingår en aktivitet (4i) som syftar till att säkerställa den långsiktiga kompetensförsörjningen inom geodataområdet. För att arbeta med frågan tillsattes en arbetsgrupp med representanter från Lantmäteriet och ett antal lärosäten. I denna rapport redovisas resultatet av den tillsatta arbetsgruppens undersökningar. Arbetet är i första hand inriktat på att hitta en väg framåt som kan leda till att kompetensen inom geodataområdet långsiktigt kan säkerställas och utvecklas. I uppdraget ingår även en internationell utblick. Denna har avgränsats till att avse våra nordiska grannländer, dvs. Norge, Finland, Danmark samt Nederländerna och Österrike. Geodataområdet har avgränsats till att omfatta följande områden:Geodesi Tekniska aspekter av geografiska informationssystem (GIS) och geografisk informationsteknologi (GIT)FjärranalysFotogrammetri inklusive laserskanningTekniskt lantmäteriMånga av slutsatserna från äldre rapporter och utredningar gäller fortfarande. Flera initiativ har genomförts för att komma till rätta med de identifierade problemen: samarbeten i olika forum, kostnadsfri tillgång till geodata för universitet och högskolor (via FUK-avtal), en förbättrad infrastruktur för geodata (genom forskning och regeringsuppdrag) samt utbildningssatsningar i tidig ålder (Geoskolan). Geodatarådets tidigare initiativ för att driva kompetensfrågorna i enlighet med 2012 års geodatastrategi har inte följts upp med motsvarande nya satsningar mellan åren 2016 till 2019.Det finns ett stort utbud av utbildningar inom geodataområdet utspridda på olika platser i Sverige. Kompetensförsörjningen inom geodataområdet är beroende av tillgången på välfungerande forskningsmiljöer. Goda forskningsmiljöer knyter till sig värdefulla resurser, exempelvis professorer, forskare, postdocs och doktorander. Förutom att bidra med kunskap och allokera ekonomiska resurser till forskning, förbättras lärosätenas möjligheter att kunna bedriva en attraktiv utbildning. Många gånger är en professur en nödvändighet för att åstadkomma den önskvärda forsknings- och utbildningsmiljön. Trots att flertalet utbildningsvarianter finns valbara vid ett antal lärosäten tycks tillgången på kompetens inte motsvara marknadens behov. Särskilt kritiskt tycks situationen vara för kompetenstillgången inom ämnesområdet fotogrammetri, där det idag inte finns någon profe-ssur i Sverige.Vid de tekniska högskolorna i Stockholm och Lund är söktrycket för de granskade utbildningarna gott, men få studenter väljer en inriktning mot geodata längre fram. Ämnesområdet geodata är relativt litet i förhållande till andra teknikområden och det finns en konkurrens mellan lärosätena. Detta har gjort ämnesområdet fragmentiserat med följden att inget lärosäte för närvarande tillhandahåller en komplett utbildnings- och forskningsmiljö. Det finns ett nationellt behov av en högkvalitativ masterutbildning som omfattar kärnämnena geodesi, fotogrammetri och geoinformatik. Om Sverige lyckas med att skapa en komplett masterutbildning som stöds av vitala forskargrupper bör det locka fler studenter till fortsätt utbildning, både på master- och forskarnivå. Forskningsverksamheten har flera viktiga funktioner i samhället. God forskning bidrar till att värna om Sveriges ställning som kunskapsnation och ger förutsättningar för vilken industri som etableras och stannar i landet. Aktiva forskargrupper bidrar till att skapa kompetensnätverk och får en särskild betydelse vid utbildningen av doktorander, lärare och studenter som sedan kan förse samhället med nödvändig expertkompetens. De ansträngningar som har gjorts för att försöka påverka forskningsfinansiärerna att prioritera geodataområdet har hittills varit fruktlösa. Medel får sökas inom ramen för andra forskningsprojekt. En långsiktig finansiell försörjning är en förutsättning för att forskning ska kunna bedrivas uthålligt och hålla en hög kvalitet. I Sverige finns det ingen utsedd huvudfinansiär för forskning inom geodataområdet, något som uppmärksammades redan i Geodatarådets utredning från 2008. Situationen ser likadan ut i dag, tillgången på forskningsmedel är bristfällig och det saknas en långsiktig forskningsförsörjning. I denna rapport presenteras en handlingsplan för att säkerställa den fram-tida kompetensuppbyggnaden inom geodataområdet. Arbetet bör initieras och följas upp av Geodatarådet samt utgöra en grund för inspel till kommande forskningsproposition (närmast år 2025) och dialog med berörda departement. Tre av de föreslagna aktiviteterna återges nedan:Arbeta för att skapa minst en komplett utbildnings- och forskningsmiljö som kan fungera som kompetenscentrum, och som inkluderar ämnesområdena geodesi, fotogrammetri (inklusive laserskanning) samt geoinformatik.Bilda en marknadsföringsgrupp med representanter från Geodatarådets medlemmar samt lärosäten och branschföretag som tillsammans arbetar fram en gemensam handlingsplan med aktivi-teter och kampanjer för att öka söktrycket till utbildningar med inriktning mot geodata.Ge Lantmäteriet ett forskningsfinansierande uppdrag. Formerna för ett sådant uppdrag behöver utredas närmare med andra forsknings-finansierande myndigheter som förebild. Denna lösning kräver ändringar i Lantmäteriets instruktion samt ett höjt ramanslag vilket måste tas med i beräkning vid ärendets beredning.

Meta-Analytical Evidence for Segregating and Integrating Brain Activation to Symptom Provocation in Social Anxiety Disorder, Specific Phobia and Post Traumatic Stress Disorder
- 2011
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Background: In PTSD increased amygdala activity is found in parallel to decreased anterior cingulate activity and this imbalance relate to symptomatology. Consistently, in healthy controls enhanced vmPFC activity suppress fear conditioning and enhance extinction similar to reappraisal studies where dPFC activation supports emotional down regulation through amygdala attenuation. It is not established if phobic disorders display a similar pattern and if treatment induced changes affect “top-down” and/or “bottom-up” mechanisms. Methods: Using a meta-analytical approach, we review brain-imaging studies using symptom provocation in patients with specific or social phobia as well as PTSD to evaluate reactivity in the ACC and the amygdala and its correlation to symptomatology. Further, amygdala ACC connectivity and the effect of CBT will be covered. Results: Functional brain imaging studies reveal increased amygdala reactivity that is correlated with symptomatology across the anxiety disorders. In phobic patients enhanced ACC responsivity is observed. The correlation between symptomatology and prefrontal brain activity is consistently negative and ACC related in PTSD while in phobic patients the relation is positive and encompass prefrontal areas outside the ACC, particularly in SAD. Connectivity patterns suggest couplings between amygdala and PFC, limited to ACC in PTSD but not in phobic disorders. Finally, CBT-treatment is associated both with increased and decreased activity in the ACC and other prefrontal areas. Conclusions: A tentative conclusion is that, even though the pattern of activity and connectivity both segregate and integrate different anxiety disorders, the ACC has a prominent role in coding and controlling affect.

Region-Specific Nutrient Intake Patterns Exhibit a Geographical Gradient within and between European Countries
- 2010

- Until recently, the study of nutrient patterns was hampered at an international level by a lack of standardization of both dietary methods and nutrient databases. We aimed to describe the diversity of nutrient patterns in the European Prospective Investigation into Cancer and Nutrition (EPIC) study at population level as a starting point for future nutrient pattern analyses and their associations with chronic diseases in multi-center studies. In this cross-sectional study, 36,034 persons aged 35-74 y were administered a single, standardized 24-h dietary recall. Intake of 25 nutrients (excluding intake from dietary supplements) was estimated using a standardized nutrient database. We used a graphic presentation of mean nutrient intakes by region and sex relative to the overall EPIC means to contrast patterns within and between 10 European countries. In Mediterranean regions, including Greece, Italy, and the southern centers of Spain, the nutrient pattern was dominated by relatively high intakes of vitamin E and monounsaturated fatty acids (MUFA), whereas intakes of retinol and vitamin D were relatively low. In contrast, in Nordic countries, including Norway, Sweden, and Denmark, reported intake of these same nutrients resulted in almost the opposite pattern. Population groups in Germany, The Netherlands, and the UK shared a fatty acid pattern of relatively high intakes of PUFA and SFA and relatively low intakes of MUFA, in combination with a relatively high intake of sugar. We confirmed large variability in nutrient intakes across the EPIC study populations and identified 3 main region-specific patterns with a geographical gradient within and between European countries.

- Social anxiety disorder (SAD) is associated with altered brain function and structure, but most structural studies include small samples and findings are mixed. This study compared regional gray matter volume between 48 SAD patients and 29 healthy controls (HC) as well as the relationship between volume and symptom severity. Structural magnetic resonance images from SAD patients and HC were evaluated using standard voxel-based morphometry (VBM) processing in the SPM8 software package. Social anxiety symptom severity was rated in SAD patients by a clinician using the Liebowitz Social Anxiety Scale (LSAS). SAD patients had greater regional gray matter volume in the lingual gyrus and lateral occipital cortex than the controls, and within the SAD group a positive correlation was found between symptom severity and regional gray matter volume in the lingual gyrus and the retrosplenial cortex. These findings replicate and extend earlier reports of enlarged visual processing areas in SAD. Increased gray matter volume in regions involved in visual processing and self-consciousness could underlie, or be the result of, abnormal emotional information processing and self-focused attention previously demonstrated in patients with SAD.

Tidskriftsartikel (refereegranskat)abstract
- Since 2006, several different groups have computed geoid and/or quasigeoid (quasi/geoid) models for the Auvergne test area in central France using various approaches. In this contribution, we compute and compare quasigeoid models for Auvergne using Curtin University of Technology’s and the Swedish Royal Institute of Technology’s approaches. These approaches differ in many ways, such as their treatment of the input data, choice of type of spherical harmonic model (combined or satellite-only), form and sequence of correction terms applied, and different modified Stokes’s kernels (deterministic or stochastic). We have also compared our results with most of the previously reported studies over Auvergne in order to seek any improvements with respect to time [exceptions are when different subsets of data have been used]. All studies considered here compare the computed quasigeoid models with the same 75 GPS-levelling heights over Auvergne. The standard deviation for almost all of the computations (without any fitting) is of the order of 30–40 mm, so there is not yet any clear indication whether any approach is necessarily better than any other nor improving over time. We also recommend more standardisation on the presentation of quasi/geoid comparisons with GPS-levelling data so that results from different approaches over the same areas can be compared more objectively.

- Cette étude propose une analyse de la proportion d’élèves suédois qui étudientle français au collège et présente une réflexion plus générale sur la situationde l’enseignement du français en Suède. À partir de données statistiques de labase de données SIRIS, mise à disposition publique par la Direction nationale desÉtablissements scolaires, les résultats montrent que, même si la proportion d’élèves qui étudient une langue moderne a augmenté de 62% en 2000 jusqu’à 72% en 2018, le français a baissé de 20% à 14% pendant la même période. Suite à des facteurs géographiques et démographiques, la langue française est surtout étudiée dans les grandes villes alors que l’apprentissage de cette langue devient de plus en plus rare dans les écoles des petites villes et des zones rurales. Depuis quelques années, le nombre de communes qui n’enregistrent aucun élève de français a augmenté.This study presents an analysis of the proportion of Swedish pupils studying French in secondary school and we discuss the role of the teaching of French in Sweden. Based on data from the database SIRIS (Skolverket), the results show that even though the proportion of pupils studying modern languages in general has increased from 62% in 2000 to 72% in 2018, the proportion of pupils studying French has decreased from 20% to 14% during the same period. The results illustrate that the varying proportion of French pupils in Sweden depends on geographic and demographic factors. French is above all studied in larger cities whereas its presence is rapidly decreasing in schools in smaller towns and rural areas. The number of municipalities without any pupils of French has increased dramatically over the last couple of years.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Artikeln sammanfattar resultat från en undersökning av muntlig språkfärdighet i franska, spanska och tyska på våren i årskurs 9. Studien är en del av det så kallad TAL-projektet, som med stöd av VR genomfördes mellan 2016 och 2019 med fokus på moderna språk. Totalt 122 elever vid 15 skolor genomförde två muntliga uppgifter, en produktiv och en interaktiv, som bedömdes med hjälp av skalor från GERS (Gemensam europeisk referensram för språk). Bedömningarna genomfördes av forskarna i projektet och av externa bedömare (totalt sju bedömare per elevprestation). Resultaten visar att färre än hälften av prestationerna bedömdes som nivå A2.1, vilket ungefärligen motsvarar miniminivån för betygssteget E i Språkvalet, åk 9. Inga stora skillnader upptäcktes mellan de två uppgiftstyperna. Däremot bedömdes nivån i tyska signifikant oftare som A2.1 eller högre jämfört med franska och spanska. I artikeln diskuteras resultaten kort i relation såväl till yttre villkor för undervisningen och för studien som till pedagogiska aspekter av undervisningen i moderna språk.

Le rôle de l’input pour le développement du vocabulaire et de la grammaire en acquisition du français par des enfants monolingues et bilingues
- 2019
-
Konferensbidrag (refereegranskat)abstract
- Entre 2009 et 2011 nous avons mené un projet de recherche à l’université de Lund (Suède) intitulé L'âge de début d’acquisition et le développement linguistique en français (Schlyter/Granfeldt) dont le but était de comparer le développement linguistique du français de trois groupes d’enfants : des enfants monolingues (L1), des enfants bilingues simultanés (2L1) et des enfants ayant le français comme langue seconde (bilingues successifs, eL2). Nous avons notamment étudié les effets respectifs de l'âge de début d'acquisition (angl. Age of Onset of Acquisition), de la quantité et qualité de l'input ainsi que de la complexité linguistique sur le développement de la morphosyntaxe. Dans le cadre de cette étude nous nous étions concentré sur le développement d’un certain nombre de structures morphosyntaxiques (la finitude morphologique, les objets clitiques, l’accord sujet-verbe, le genre) que nous avions déjà étudié chez l’apprenant adulte L2 (Granfeldt, 2003; Ågren, 2008; Thomas, 2009) et chez les enfants L1 et 2L1 (Schlyter, 2003, Granfeldt, 2003, Granfeldt & Schlyter, 2004). Dans l’ensemble, les résultats ont montré que pour les structures morphosyntaxiques simples et (très) précoces en L1, le développement initial en eL2 suivait les itinéraires d’acquisition des apprenants aL2, même chez les eL2 dont l'âge de début d'acquisition se situe avant 4 ans. En revanche, pour les structures complexes et tardives en L1, nous avons plutôt observé le même développement en (2)L1 et en eL2 ainsi qu'une plus grande importance de l'input (Ågren, Granfeldt & Thomas, 2014). Une conclusion centrale de cette partie du projet est alors qu’au niveau des itinéraires d’acquisition, les structures morphosyntaxiques de français ne sont pas toutes pareilles : certaines sembleraient plus dépendantes de l’âge de début d’acquisition (finitude, placement des objets clitiques) alors que d’autres (attribution du genre, accord-sujet verbe) montrent de meilleures corrélations avec la quantité et de la qualité de l’input. Dans cette communication nous reviendrons sur un certain nombre de résultats dans le domaine du développement grammatical (Ågren, Granfeldt & Thomas, 2014) pour ensuite les comparer au développement de la richesse et de la précision du vocabulaire chez les mêmes enfants. La question est de savoir s’il existe une relation entre le développement du vocabulaire et de la morphosyntaxe, une question qui se pose depuis les origines des recherches systématiques en acquisition (cf. Brown, 1973). Dans une approche chomskyenne classique (principe et paramètres/gouvernement et liage) la syntaxe et le lexique sont des modules distincts alors que dans sa version récente (Minimalisme, Chomsky, 1995), Chomsky attribue les différences syntaxiques entre les langues aux propriétés du lexique, ce qui a eu des conséquences pour les théories d’acquisition ancrées dans cette perspective (cf. Granfeldt, 2003). Dans cette optique, les itinéraires développementaux sont facteurs de l’âge du début d’acquisition. Par contre, dans une approche basée sur l’usage de la langue (N. Ellis, 2002, Bybee, 2008) l’acquisition d’une langue est étroitement liée aux caractéristiques de l’input langagier ainsi qu’au traitement cognitif de celui-ci, et conçoit la relation entre lexique et grammaire comme un continuum. Dans le but de mieux comprendre la possible interdépendance entre lexique et morphosyntaxe, il nous faut plus d’études empiriques, qui, comme nous le proposons ici, combinent l’étude du développement lexical et morphosyntaxique avec différents types d’apprenant·e·s ayant différentes situations d’input. Pour les enfants L1 et 2L1, les recherches antérieures ont montré qu’il y a un effet d’input sur l’acquisition du vocabulaire (Pearsson et al., 1997, Thordardottir, 2011), mais peu de recherches ont fait ce que nous proposons ici, à savoir comparer les effets longitudinaux de la quantité et de la qualité de l’input sur le développement du vocabulaire et de la grammaire chez différents groupes d’enfants francophones (L1, 2L1 et eL2). Vu les résultats antérieurs, notre hypothèse est qu’il doit y avoir une corrélation entre le développement des structures grammaticales qui se sont avérées surtout dépendantes de l’input et le développement du vocabulaire. Les données de production proviennent d’un corpus longitudinal d’enfants francophones bilingues successifs (eL2, n=3), d’enfants bilingues simultanés (2L1, n=3) et d'enfants monolingues (L1, n=3), tous allant à la même école française en Suède. Les enfants ont été suivi pendant près de trois ans avec des enregistrements à des intervalles réguliers. L’analyse sera basée sur des tâches de production élicitée et des enregistrements de conversations libres avec les enfants. La notion de quantité et de qualité de l’input sera opérationnalisée pour chaque enfants à l’aide de profils d’input individuels et le vocabulaire Résumé pour le XXIXe Congrès International de Linguistique et de Philologie Romanes (Copenhague, 2019) Granfeldt, Ågren & Thomas sera mesuré à la fois quantitativement (la diversité du vocabulaire, VocD, Malvern et al., 2004) et qualitativement (la précision du vocabulaire). La présente étude sera centrée sur les questions de recherche suivantes : 1) La richesse du vocabulaire, mesurée par la diversité lexicale (VocD), diffère-t-elle entre enfants L1, 2L1 et eL2 de notre corpus ? 2) La richesse du vocabulaire (VocD) augmente-t-elle avec la durée d’exposition à la langue ? 3) L’effet de la quantité et de la qualité de l’input (mesuré par un profil d’input) est-il le même sur le développement du vocabulaire que sur le développement des structures grammaticales étudiées auparavant ? Y-a-t-il des différences entre les trois groupes d’enfants ? Les résultats montrent que les trois groupes d’enfants diffèrent au niveau de la diversité lexicale : les enfants L1 se distinguent de façon significative des enfants 2L1 qui, à leur tour, se distinguent des enfants eL2. Au niveau des groupes, un profil d’input plus fort semble donc se refléter en une diversité lexicale plus riche. Pourtant, nos analyses montrent que l’ampleur de la différence en termes de diversité lexicale entre groupes semble plus faible en vocabulaire qu’en grammaire (e.g. l’accord sujet-verbe). Autrement dit, l’effet de l’input pourrait être plus grand sur le vocabulaire que sur la structure syntaxique la plus susceptible d’être influencée par la quantité et la qualité d’input. En outre, contrairement à ce qui a été observé pour le développement grammatical, nous n’avons pas trouvé de corrélation entre le développement longitudinal des scores de diversité lexicale des enfants 2L1 et eL2 et leurs profils d’input. Il s’avère que le développement lexical, tel qu’il a été mesuré dans cette étude, n’évolue pas chez les trois enfants 2L1 alors que les enfants L2 ne montrent que de faibles signes de développement dans le domaine du vocabulaire. Ces observations seront discutées à la lumière des limitations possibles des mesures générales comme le VocD. Une analyse qualitative de la précision lexicale montre que les enfants eL2, et à un moindre degré les enfants 2L1, ont plus souvent recours à des verbes « passe-partout » (General Purpose Verbs, GAP, Harley, 1992) que les enfants L1, comme le montre les productions d’enfants dans un contexte qui ciblait la construction « emballer le cadeau » : (1) L1 Lina « ils l’emballent le cadeau… » (2) 2L1 Linnéa « ils commencent à faire le cadeau » (3) eL2 Hannes « après ils font le paquet pour l’anniversaire » Nous montrerons que les stratégies utilisées par les enfants 2L1 et eL2, notamment l’évitement, la paraphrase, la généralisation, jouent un rôle important dans le développement du vocabulaire. Le choix de la section Acquisition, apprentissage et enseignement des langues nous semble la plus pertinente pour cette communication. Avec notre accent sur la quantité et la qualité d’input, la proposition s’aligne bien avec des question sur « la complexion des variables interagissant dans l’apprentissage-enseignement des langues secondes et étrangères romanes ». Notre proposition est innovatrice puisqu’il existe peu d’études qui combinent le développement du lexique et de la morphosyntaxe dans une perspective longitudinale. Ensuite, les données sur l’acquisition du français par des enfants L2 sont très rares parmi les études récentes sur l’acquisition.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- De tre stora moderna språken i svensk skola –spanska, tyska och franska –erbjuds på en majoritet av grundskolorna, men det finns regionala skillnader både vad gäller skolornas utbud och elevernas språkval. Attityderna till moderna språk är positiva bland de rektorer, lärare och elever som deltagit i vårt projekt. När det gäller elevernas motivation att lära, vilja att tala eller oro för att tala språket i klassrummet såg vi inga tydliga skillnader i de tre språken. Att fritt kunna tala och samtala på språken är en kommunikativ färdighet som eleverna behöver få mer tillfälle att utveckla.

Second foreign languages in the Swedish school context - The views of school leaders
- 2017
-
Konferensbidrag (refereegranskat)abstract
- Politicians and stakeholders widely support the “mother tongue plus two” language policy (European Commission) according to which all European citizens should be able to communicate in at least two foreign languages (FLs). However, despite high political and societal ambitions, recent reports suggest that FLs other than English are suffering in Europe and Sweden is no exception to this trend. One third of all Swedish pupils starting to study a second FL (French, German or Spanish) in lower secondary school abandon the subject within three years (Tholin & Lindqvist, 2009). In fact, second FLs are the only subjects lacking a mandatory status in the Swedish compulsory school. Moreover, according to the Eurobarometer (2012) there is a lack of motivation for language learning. Sweden is the only country among the surveyed countries where a majority says that lack of motivation is a reason that dissuades them from learning another language, but we know very little about how views and attitudes towards FLs are shaped in the school context. The overall aim of the TAL-project (Teaching, Assessment and Learning) is to gain a better understanding of learning conditions and outcomes in FLs other than English in the Swedish school context. The project is interdisciplinary and draws on research in education, language teaching, language assessment and language learning. The project runs from 2016 through 2018 and involves data collection in several phases. In a first phase we have surveyed 425 Swedish compulsory schools starting with a head teachers' questionnaire. This questionnaire aims to survey relevant educational frame factors and provide a picture of how foreign languages are organised and perceived in a representative selection of Swedish schools. In this presentation, we will discuss responses to the questions concerning head teachers' view of foreign languages in school, e.g. the perceived status of the subject, the attitudes towards a mandatory second foreign language and challenges for the future. Seemingly little research has focused on head teachers' view of modern languages and its impact on teaching and student outcomes, but educational research shows that sayings, doings and relatings within an educational setting will contribute in the shaping of a praxis (Kemmis, 2009). The results of the survey will be discussed in relation to the headmasters' own educational background and to educational and regional aspects of the different schools.ReferencesEurobarometer.
