Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Det sociala arbetets praktik handlar om att ge hjälp och stöd och förhindra exkludering och främja delaktighet. Socialt arbete handlar till stor del om att tillämpa befintliga lagar utifrån det tolkningsutrymme som finns. I varje enskilt fall vägs en rad individuella omständigheter samman med tolkningar av denna lagstiftning. Det är bl.a. inom ramen för detta handlingsutrymme som de sociala rättigheterna görs tillgängliga och blir till. Därför har kopplingen mellan rättigheter och socialt arbete stor betydelse för det sociala arbetet, både som praktik och som forskningsfält. I den här antologin riktar författarna uppmärksamhet mot sociala rättigheter utifrån olika teoretiska infallsvinklar, metoder och empiriska fokuspunkter. Med stöd i exempel från en svensk kontext behandlar författarna tolkning och tillämpning av sociala rättigheter. Hur får de olika innebörder beroende på vilket system som ska säkerställa dem? Hur återskapas de och ges delvis nytt innehåll när en domstol uttolkar ett begrepp? Bokens avslutande kapitel handlar om förhandlingar om olika sociala rättigheter, t.ex. rätten till meningsfulla fritidsaktiviteter för barn och unga med intellektuell funktionsnedsättning, ansvar och rätten till vård och omsorg när det gäller anhörigvård samt rätten till språkutbildning för nyanlända.

Det offentliga som konkurrent på kommersiella marknader - En samhällsekonomisk analys med exemplet konferensmarknaden
- 2017
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- I den här rapporten analyseras samhällsekonomiska effekter av att det offentliga konkurrerar med privata företag på kommersiella marknader. Den innehåller även en pilotstudie av marknaden för en – och tvådagarskonferenser tillämpad på Umeåregionen.Svensk konkurrenslagstiftning inkluderar regler om konkurrensbegränsande offentlig säljverksamhet. Reglerna gäller för den offentliga sektorn i sin helhet, dvs stat, primärkommuner (kommun) eller landstingskommuner (landsting) och juridiska personer vars verksamhet den offentliga sektorn har ett dominerande inflytande över. Inflytandet kan ta sig formen av ägande, finansieringsvillkor, styrelse, lag och avtal. Frågan om det offentliga som konkurrent är även samhällsekonomiskt relevant då snedvridning av konkurrens i form av exempelvis underprissättning till följd av stöd, kan innebära en samhällsekonomisk förlust.Sammantaget visar den samhällsekonomiska analysen att det inte går att dra några generella slutsatser om att konkurrens från den offentliga sektorn på marknader med en etablerad kommersiell verksamhet alltid är problematisk. Även i situationer där konkurrensen sker på olika villkor kan fördelarna med den offentliga aktörens medverkan överväga nackdelarna. Baserat på pilotstudien och olika scenarios avseende konferensmarknaden i Umeå, är det möjligt att dra slutsatsen att fördelarna med offentliga aktörer kan dominera nackdelarna under förutsättning att den offentliga aktörens produktionskostnad maximalt är en procent högre än en privat aktörs produktionskostnad för motsvarande konferens. Analysen visar att subventioner till offentliga aktörer överskridande 1,3 miljoner kronor inte kan motiveras utifrån ett samhällsekonomiskt perspektiv i något scenario. I scenariot där den offentliga aktören ägnar sig åt underprissättning överväger nackdelarna även om verksamheten klarar sig utan subvention.

Tidskriftsartikel (refereegranskat)abstract
- We have investigated 20 consanguineous families with multiple children affected by rare disorders. Detailed clinical examinations, exome sequencing of affected as well as unaffected family members and further validation of likely pathogenic variants were performed. In 16/20 families, we identified pathogenic variants in autosomal recessive disease genes (ALMS1, PIGT, FLVCR2, TFG, CYP7B1, ALG14, EXOSC3, MEGF10, ASAH1, WDR62, ASPM, PNPO, ERCC5, KIAA1109, RIPK4, MAN1B1). A number of these genes have only rarely been reported previously and our findings thus confirm them as disease genes, further delineate the associated phenotypes and expand the mutation spectrum with reports of novel variants. We highlight the findings in two affected siblings with splice altering variants in ALG14 and propose a new clinical entity, which includes severe intellectual disability, epilepsy, behavioral problems and mild dysmorphic features, caused by biallelic variants in ALG14.

Tidskriftsartikel (refereegranskat)abstract
- The impact of skin diseases on health-related quality of life is considerable. It is important to quantify the patient's perspective of the severity of their disease. Health-related quality of life was measured in 366 patients with skin diseases attending the dermatology outpatient clinic in Uppsala, Sweden, from November 1996 to December 1997, with 1 generic (SF-36) and I disease-specific (DLQI) health-related quality of life instrument, and a subjective measure of disease activity. The SF-36 mean scores were below those of the age- and gendermatched general population in Sweden. No difference in health-related quality of life was found between men and women or between patients with atopic dermatitis and psoriatic patients. However, patients with psoriatic arthritis had significantly poorer health-related quality of life than both patients with atopic dermatitis and psoriatic patients. The estimated correlations between the instruments were in the expected direction and mostly significant. The results confirm that skin diseases have an adverse impact on patients' health-related quality of life.

Konferensbidrag (refereegranskat)abstract
- This paper presents preliminary analysis of the data from measurements on a minefield in Croatia done in the international cooperation project Airborne Minefield Area Reduction (ARC). Temperature differences above and around suspected mines and minefield indicators, were recorded with a long wave IR camera in 8-9 micrometers , over a time of several days, capturing data under different weather conditions. The data are compared to simulations of land mines, minefield indicators and other objects using a themodynamic FEM model, developed at FOI. Different detection methods are presented and applied to the data.

De mänskliga rättigheternas framväxt

Ingår i: De sociala rättigheternas politik. - 9789151109855 ; , s. 49-49

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Det är viktigt att förstå att rättigheter kan etableras och utvecklas i en viss tid, för att i en annan tid utmanas, urholkas och ersättas av skyldigheter. Olika rättighetskategorier kan få olika tyngd i förhållande till varandra. Ett exempel belyses i detta kapitel, om de mänskliga rättigheternas framväxt i ett internationellt sammanhang. Bland annat behandlar kapitlet hur det kommer sig att ekonomiska och sociala rättigheter har fått en svagare ställning än politiska och medborgerliga rättigheter rent juridiskt. Skillnaden i juridisk tyngd mellan olika rättighetskategorier har på olika sätt betydelse för hur rättigheter institutionaliseras, och i förlängningen även för hur de används i det sociala arbetet och dess vardagliga praktik. Det är till exempel svårare att driva frågor i rättsliga processer som inte har en tydlig juridisk tyngd att falla tillbaka på.

Modelling operator control work across traffic management domains : implications for interaction design
- 2024
-
Ingår i: Cognition, Technology & Work. - : Springer. - 1435-5558 .- 1435-5566.
-
Tidskriftsartikel (refereegranskat)abstract
- Traffic management in aviation, shipping, and rail transport shows similarities and dissimilarities in the work process. For example, they share the temporal aspect, but different levels of urgency in the control work set different requirements on monitoring, decisions, and actions. However, few studies have been presented that model and compare the different domains in terms of temporal decision-making. The Joint Control Framework (JCF) is an approach to analyse and temporally model operators’ control processes from a cognitive systems engineering perspective. In this study, we have used JCF to map, and compare, cognitive joints, such as perceptions, decisions, and actions, in temporally challenging control situations in air traffic control, maritime vessel traffic service, and train traffic management. Data was collected collaboratively with traffic operators, focusing on (1) identifying challenging traffic situations and (2) jointly modelling the temporal decision-making patterns of these situations using simplified JCF. Post-analysis was done by breaking down the results into different processes and comparing domains to ascertain how operators maintain control. An intermediate level of activity—between general monitoring and work with specific vehicles—was identified: processes-in-focus. A shared problem arises in the shift between general monitoring and the processes-in-focus. All processes-in-focus comprise cognitive joint cycles of perceptions, decisions, and actions. However, depending on the framing of processes-in-focus, the patterns of joints, such as temporal extension and complexity, differ. In the remainder of the article, implications for the interaction design, in particular the potential for human–AI/automation teaming with higher levels of automation and cognitive autonomy, are discussed.

Spatial modeling of occlusion patterns applied to the detection of surface-laid mines
- 2004
-
Ingår i: Detection and Remediation Technologies for Mines and Minelike Targets IX. - : SPIE. ; , s. 799-810
-
Konferensbidrag (refereegranskat)abstract
- Images recorded in ground areas potentially containing surface laid land mines are considered. The first hypothesis is that the image is of clutter (grass) only, while the alternative is that the image contains a partially occluded (covered) land mine in addition to the clutter. In such a scenario, the occlusion pattern is unknown and has to be treated as a nuisance parameter. In a previous paper it was shown that deterministic treatment of the unknown occlusion pattern, in companion with the applied model, renders a substantial increase in detector performance as compared to employment of the traditional additive model. However, a deterministic assumption ignores possible correlation and additional gains could be possible by taking the spatial properties into account. In order to incorporate knowledge regarding the occlusion, the spatial distribution is characterized in terms of an underlying Markov Random Field (MRF) model. A major concern with MRF models is their complexity. Therefore, in addition to this, a less computationally demanding technique to accommodate the occlusion behavior is also proposed. The main purpose of this paper is to investigate if significant gains are possible by acknowledging the spatial dependence. Evaluation on data using real occluded targets however indicates that the gain seem to be marginal.

Tidskriftsartikel (refereegranskat)abstract
- The response of a matrix of 25 lead tungstate (PWO) scintillator detectors, operated at -25 degrees C, to photons in the range 13 MeV-64 MeV has been measured at the tagged-photon facility at MAX-lab, Lund. The tapered PWO crystals, each with a length of 200 mm and a cross-section of 24.4 x 24.4 mm(2) in the front end, read out by 19 mm photomultiplier tubes, were arranged in a 5 x 5 matrix. The response was measured for photons directed towards the centre of the central crystal as well as for photons directed towards the corner of the central crystal, where four crystals meet. The obtained energy resolution surpasses what has been published so far and is close to the limit given by Poisson statistics and escaped energy. For photons directed towards the centre(corner) of the central crystal the relative energy resolution, defined as (FWHM/2.35)/E-gamma, decreases from 7.3%(11.0%) at E-gamma = 13 MeV to 3.3%(3.6%) at E-gamma = 64 MeV. The reconstructed point of impact of a photon in this energy range is determined with an uncertainty (one standard deviation) of 7.3 +/- 0.1 mm.

Flexibel automation för trafikledning inom luftfart, sjöfart och tågtrafik
- 2024
-
Ingår i: Sammanställning av referat från Transportforum 2024. - Linköping : Statens väg- och transportforskningsinstitut. ; , s. 441-442
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Dagens trafikledningssystem inom luftfart, sjöfart och tågtrafik, med många/stora displayer och en förhållandevis låg grad av automation och systemintegration medför risker. En stor risk, som validerats i tornsimulatorn på Arlanda är att operatören inte alltid lägger märke till händelseförlopp som visas på displayerna. Nya sensorer som mer ger information för att övervaka processen (exempelvis fåglar på flygplatser), genererar samtidigt mer data som ska presenteras för operatören. I detta forskningsprojekt föreslår vi en ny strategi, där automationen förstärks med sensorer som ger automationen information om den mänskliga operatören och om miljön. Projektet Flexibel Automation F AUTO utforskar interaktion och gränssnittskoncept (HMI) samt sensorteknik för en ny generation av adaptiv automation. En adaptiv automation innebär att systemet situationsanpassar operatörsstödet, t.ex. till mängden trafik, för att varken överbelasta trafikledaren eller ge denne för lite att göra. De huvudsakliga frågeställningarna är: Hur kan adaptiv presentation av lägesbild utformas för att dra nytta av sensorer i operatörsmiljön för att stärka samarbete människa-automation?Hur väl fungerar denna design, vilka egenskaper har den, särskilt angående effektivitet och säkerhet?Vilka typer av sensorer och vilka sensordata är mest lämpliga, och hur kan dessa data representeras visuellt för en ökad effektivitet? Projektet följer en metodik där koncepten utforskas iterativt. I tidiga skeden värderades koncept i workhops med flygledare och med andra intressenter. En metodik som använts i senare skeden av konceptutveckling är så kallade human-in-the-loop studies (HITL). I dessa sammanhang användes en simulator för att värdera hur koncepten fungerar i reell användning. Sensorutveckling med integration i konceptet har vidareutvecklats parallellt. Projektet har byggt upp en teknisk miljö för att kunna testa flexibel automation i olika operativa miljöer i tre domäner. I den här presentationen fokuserar vi särskilt på ett huvudkoncept från projektet, "reduced autonomy workspace". Det är ett koncept för att hantera situationer där automationen måste kontakta operatören för att optimera processtyrning, genom en "reduced autonomy workspace", som ska minska stress i sådana situationer. Vi följer också upp ett resultat som presenterades förra året, mjuka visuella påminnelser (soft visual cues). I år ger vi exempel på utformning och tillämpning i domänerna - med avseende på teknik, design, och operativ anpassning.

Optical detection of land mines at FOI
- 2001
-
Ingår i: Subsurface and Surface Sensing Technologies and Applications III. - Bellingham, Wash : SPIE - International Society for Optical Engineering. - 0819442054
-
Konferensbidrag (refereegranskat)abstract
- This paper presents activities concerning optical detection of landmines at FOI, former FOA. The work is focused on the understanding of the origin of detectable optical signatures for choosing the most favorable conditions for detection. Measurements in test beds and calculations using a thermodynamic FEM model with conditions similar to those of the measurements are compared and interpreted in order to explain the behavior of the contrast. Examples will be given on modeling of buried landmines in soil. The heat flow as well as moisture flow has been taken into consideration. The diurnal heat exchange between the soil surface and the atmosphere generates the contrasts in the infrared images. Calculated temperature differences between the background and the surface above the buried object are compared to measured data from experiments. Results are presented and show how the temperature differences can vary over a 24-hour period. The variation depends on the weather at the time as well as the weather before the measurements started. Results from processing and analysis of temporal variations of optical signals from buried landmines and backgrounds are presented as well as their relation to weather parameters. A detection approach including the Likelihood Ratio Test (LRT) is presented. Some of the work has been carried out in an international cooperation project, Airborne Minefield Area Reduction (ARC). The objective is to develop, demonstrate and promote a new system for performing the UN Level 2 surveys allowing a quick reduction of suspected mine polluted areas and post cleaning quality control.

Omfördelning, erkännande, representation : – Nancy Frasers teori om rättvisa

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Nancy Frasers arbete är ett exempel på kritik som en rad teoretiker har riktat mot Marshall, och inte minst mot hans förgivettagande att nationen är den givna ram inom vilken medborgarskap, det vill säga rättigheter av olika slag, anordnas och tillhandahålls. Även om vi i dag lever i en tid av globalisering och världsomspännande migration där rörlighet är mer regel än undantag, så är nationalismens ideal om tillhörighet till gemenskapen – grundad på kultu- rell homogenitet och enhetlighet – inte på något vis överspelade. Tvärtom lever sådana ideal fortfarande kvar, tas ofta för givna och är i många länder på frammarsch. Nationalstaten sätter på så sätt fortsatt prägel på samtida politiska debatter och bidrar på olika vis till att forma medborgarskap och dess rättigheter – både i Sverige och i många andra länder runt om i världen

Tidskriftsartikel (refereegranskat)abstract
- Inflammation is one of the hallmarks of carcinogenesis. High mammographic density has been associated with increased risk of breast cancer but the mechanisms behind are poorly understood. We evaluated whether breasts with different mammographic densities exhibited differences in the inflammatory microenvironment.Postmenopausal women attending the mammography-screening program were assessed having extreme dense, n = 20, or entirely fatty breasts (nondense), n = 19, on their regular mammograms. Thereafter, the women were invited for magnetic resonance imaging (MRI), microdialysis for the collection of extracellular molecules in situ and a core tissue biopsy for research purposes. On the MRI, lean tissue fraction (LTF) was calculated for a continuous measurement of breast density. LTF confirmed the selection from the mammograms and gave a continuous measurement of breast density. Microdialysis revealed significantly increased extracellular in vivo levels of IL-6, IL-8, vascular endothelial growth factor, and CCL5 in dense breast tissue as compared with nondense breasts. Moreover, the ratio IL-1Ra/IL-1 was decreased in dense breasts. No differences were found in levels of IL-1, IL-1Ra, CCL2, leptin, adiponectin, or leptin:adiponectin ratio between the two breast tissue types. Significant positive correlations between LTF and the pro-inflammatory cytokines as well as between the cytokines were detected. Stainings of the core biopsies exhibited increased levels of immune cells in dense breast tissue.Our data show that dense breast tissue in postmenopausal women is associated with a pro-inflammatory microenvironment and, if confirmed in a larger cohort, suggests novel targets for prevention therapies for women with dense breast tissue.

- Colloids and nanoparticles leached from agricultural land are major carriers of potentially bioavailable nutrients with high mobility in the environment. Despite significant research efforts, accurate knowledge of macronutrients in colloids and nanoparticles is limited. We used multi-elemental synchrotron X-ray fluorescence (XRF) microscopy with multivariate spatial analysis and X-ray atomic absorption near-edge structure (XANES) spectroscopy at the P and S K-edges, to study the speciation of P and S in two fractions of leached particles, >0.45 and <0.45 mu m respectively, collected from four tile-drained agricultural sites in Sweden. P K-edge XANES showed that organic P, followed by P adsorbed to surfaces of aluminum-bearing particles were the most common forms of leached P. Iron-bound P (Fe-P) forms were generally less abundant (0-30 % of the total P). S K-edge XANES showed that S was predominantly organic, and a relatively high abundance of reduced S species suggests that redox conditions were adverse to the persistence of P bound to Fe-bearing colloids in the leachates. Acid ammonium-oxalate extractions suggested that P associated with Al and Fe (Al-P and Fe-P) in most cases could be explained by the adsorption capacity of non-crystalline (oxalate-extractable) oxides of Al and Fe. These results improve our understanding of particulate P and S speciation in the vadose zone and helps in developing effective technologies for mitigating colloidal driven eutrophication of water bodies near agricultural land.

Forskningsöversikt (refereegranskat)abstract
- The Human Proteome Organization (HUPO) launched the Human Proteome Project (HPP) in 2010, creating an international framework for global collaboration, data sharing, quality assurance and enhancing accurate annotation of the genome-encoded proteome. During the subsequent decade, the HPP established collaborations, developed guidelines and metrics, and undertook reanalysis of previously deposited community data, continuously increasing the coverage of the human proteome. On the occasion of the HPP’s tenth anniversary, we here report a 90.4% complete high-stringency human proteome blueprint. This knowledge is essential for discerning molecular processes in health and disease, as we demonstrate by highlighting potential roles the human proteome plays in our understanding, diagnosis and treatment of cancers, cardiovascular and infectious diseases.

Konferensbidrag (refereegranskat)abstract
- In recent years, data visualization has become a major area in Digital Humanities research, and the same holds true also in linguistics. The rapidly increasing size of corpora, the emergence of dynamic real-time streams, and the availability of complex and enriched metadata have made it increasingly important to facilitate new and innovative approaches to presenting and exploring primary data. This demonstration showcases the uses of Virtual Reality (VR) in the visualization of geospatial linguistic data using data from the Nordic Tweet Stream (NTS) project (see Laitinen et al 2017). The NTS data for this demonstration comprises a full year of geotagged tweets (12,443,696 tweets from 273,648 user accounts) posted within the Nordic region (Denmark, Finland, Iceland, Norway, and Sweden). The dataset includes over 50 metadata parameters in addition to the tweets themselves.We demonstrate the potential of using VR to efficiently find meaningful patterns in vast streams of data. The VR environment allows an easy overview of any of the features (textual or metadata) in a text corpus. Our focus will be on the language identification data, which provides a previously unexplored perspective into the use of English and other non-indigenous languages in the Nordic countries alongside the native languages of the region.Our VR prototype utilizes the HTC Vive headset for a room-scale VR scenario, and it is being developed using the Unity3D game development engine. Each node in the VR space is displayed as a stacked cuboid, the equivalent of a bar chart in a three-dimensional space, summarizing all tweets at one geographic location for a given point in time (see: https://tinyurl.com/nts-vr). Each stacked cuboid represents information of the three most frequently used languages, appropriately color coded, enabling the user to get an overview of the language distribution at each location. The VR prototype further encourages users to move between different locations and inspect points of interest in more detail (overall location-related information, a detailed list of all languages detected, the most frequently used hashtags). An underlying map outlines country borders and facilitates orientation. In addition to spatial movement through the Nordic areas, the VR system provides an interface to explore the Twitter data based on time (days, weeks, months, or time of predefined special events), which enables users to explore data over time (see: https://tinyurl.com/nts-vr-time).In addition to demonstrating how the VR methods aid data visualization and exploration, we will also briefly discuss the pedagogical implications of using VR to showcase linguistic diversity.

- We demonstrate an approach that utilizes immersive virtual reality (VR) to explore and interact with corpus linguistics data. Our case study focuses on the language identification parameter in the Nordic Tweet Stream corpus, a dynamic corpus of Twitter data where each tweet originated within the Nordic countries. We demonstrate how VR can provide previously unexplored perspectives into the use of English and other non-indigenous languages in the Nordic countries alongside the native languages of the region and showcase its geospatial variation. We utilize a head-mounted display (HMD) for a room-scale VR scenario that allows 3D interaction by using hand gestures. In addition to spatial movement through the Nordic areas, the interface enables exploration of the Twitter data based on time (days, weeks, months, or time of predefined special events), making it particularly useful for diachronic investigations.In addition to demonstrating how the VR methods aid data visualization and exploration, we briefly discuss the pedagogical implications of using VR to showcase linguistic diversity. Our empirical results detail students’ reactions to working in this environment. The discussion part examines the benefits, prospects and limitations of using VR in visualizing corpus data.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- In recent years domestic violence has become an issue of major importance in Sweden. This is a fact to be observed in mass media but also in changes made in legislation. As concern and attention raises, new victim groups are "discovered". Among these we find women who have come to Sweden as refugees, through their marriage to Swedish men, or when reunited with a husband who arrived earlier. These women are often believed to be in greater danger to be fysically abused by their husbands and to have greater difficulties to coop with the situation than for example Swedish women. This due to the fact that they may have language problems, a lack of knowledge of the Swedish society, but also because of their cultural heritage. The empirical material in this study consists of cases of violence against women, collected from the special unit of social services to which immigrants are referred. Interviews were also made with a selected number of immigrant women and social workers. The study aims at analysing several aspects of the women´s lifes, not only the violence they experience from their partners. Such aspects are the exile situation and the cultural background of the families,but also value conflicts experienced in cultural norms, gender perspectives and human rights. Interviews with social workers focus om what actions they took in order to help the battered women, how they perceive these women, and problems when helping them.

Tidskriftsartikel (refereegranskat)abstract
- ntroduction Simulation has become an established method for education and training of Emergency Medical Services personnel in different skills such as advanced airway techniques, also in evaluation and initial care of stroke patients and in pre - hospital trauma. Simula tion can be a useful method to improve learning. To our knowledge, there are only a few studies that relate simulation to the effect on clinical skills. The aim of the present study was to investigate the effect of simulation on the clinical competence in a pre - hospital trauma care course for ambulance nurses. Methods The study was performed using a before - after design. Seventeen ambulance nurse students who participated in a trauma care course were evaluated in two simulated trauma cases. All subjects had passed the initial theoretical part of the course. The pre - test was performed in the beginning of the following part of the course involving simulation and the post - test at the end of the course. The analysis was performed by assessment of performance, as seen on video - tapes from the pre - tests and the post - tests. A validated instrument was used to determine the level of student’ s clinical competence. Paired t - test was used to confirm differences between the pre - test and post - test results . Results There was a significant increase in the over - all results for the post - test, with a difference of 1.12 points (t=4.642, df=16, p= 0.001) Situation Awareness, Patient Assessment and Decision Making showed the most pronounced improvements. Conclusion The results imply t hat simulation in addition to traditional theoretical education improves the clinical competence of the students, in comparison to traditional education and training without any significant amount of simulation.

Measuring participants’ immersion in healthcare simulation : the development of an instrument
- 2016
-
Ingår i: Advances in Simulation. - : BioMed Central. - 2059-0628. ; 2016:1
-
Tidskriftsartikel (refereegranskat)abstract
- BackgroundImmersion is important for simulation-based education; however, questionnaire-based instruments to measure immersion have some limitations. The aim of the present work is to develop a new instrument to measure immersion among participants in healthcare simulation scenarios.MethodsThe instrument was developed in four phases: trigger identification, content validity scores, inter-rater reliability analysis and comparison with an existing immersion measure instrument. A modified Delphi process was used to develop the instrument and to establish validity and reliability. The expert panel consisted of 10 researchers. All the researchers in the team had previous experience of simulation in the health and/or fire and rescue services as researchers and/or educators and simulation designers. To identify triggers, the panel members independently screened video recordings from simulation scenarios. Here, a trigger is an event in a simulation that is considered a sign of reduced or enhanced immersion among simulation participants.ResultsThe result consists of the Immersion Score Rating Instrument (ISRI). It contains 10 triggers, of which seven indicate reduced and three enhanced immersion. When using ISRI, a rater identifies trigger occurrences and assigns them strength between 1 and 3. The content validity analysis shows that all the 10 triggers meet an acceptable content validity index for items (I-CVI) standard. The inter-rater reliability (IRR) among raters was assessed using a two-way mixed, consistency, average-measures intra-class correlation (ICC). The ICC for the difference between weighted positive and negative triggers was 0.92, which indicates that the raters are in agreement. Comparison with results from an immersion questionnaire mirrors the ISRI results.ConclusionsIn conclusion, we present a novel and non-intrusive instrument for identifying and rating the level of immersion among participants in healthcare simulation scenarios.

- Stroke is a serious condition and the stroke chain of care is a complex. The present study aims to explore the impact of a computerised decision support system (CDSS) for the prehospital stroke process, with focus on work processes and performance. The study used an exploratory approach with a randomised controlled crossover design in a realistic contextualised simulation experiment. The study compared clinical performance among 11 emergency medical services (EMS) teams of 22 EMS clinicians using (1) a computerised decision support system (CDSS) and (2) their usual paper-based process support. Data collection consisted of video recordings, postquestionnaires and post-interviews, and data were analysed using a combination of qualitative and quantitative approaches. In this experiment, using a CDSS improved patient assessment, decision making and compliance to process recommendations. Minimal impact of the CDSS was found on EMS clinicians’ self-efficacy, suggesting that even though the system was found to be cumbersome to use it did not have any negative effects on self-efficacy. Negative effects of the CDSS include increased on-scene time and a cognitive burden of using the system, affecting patient interaction and collaboration with team members. The CDSS’s overall process advantage to the prehospital stroke process is assumed to lead to a prehospital care that is both safer and of higher quality. The key to user acceptance of a system such as this CDSS is the relative advantages of improved documentation process and the resulting patient journal. This could improve the overall prehospital stroke process.

Tidskriftsartikel (refereegranskat)abstract
- The purpose of this paper is to investigate regional effects of military base closures in Sweden during the last decades. Our analysis is based on a regional growth model, where two equations are estimated; one equation describing the average income growth rate and one equation describing the net migration rate. The data set is a panel of 31 Swedish municipalities covering the period 1983-1998. Our main finding is that a closure of a military base has not had any significant impact on the subsequent average income growth rate nor the net migration rate in the affected municipalities. One potential explanation for these results relates to the labor market and the composition of the labor force.

Regional Effects of Military Closures : The case of Sweden
- 2005
-
Rapport (populärvet., debatt m.m.)abstract
- This paper concerns the effects of military closures on the local growth pattern in Sweden during the last decades. The main issue is to analyze to what extent the closures have affected the subsequent average income growth and net migration rates at the local level. The analysis is based on a data set covering Swedish municipalities with military bases during the period 1983-1998. Our main finding is that the closures have not had any significant impact on the subsequent income growth rate or the net migration rate in the affected minicipalities compared to other municipilaties. However, in accordance with previous studies based on Swedish data, we find the initial endowment of human capital to have a positive impact on the subsequent growth rate.

Tidskriftsartikel (refereegranskat)abstract
- Major depressive disorder (MDD) is highly prevalent in individuals with anorexia nervosa (AN) and is a predictor of greater clinical severity. However, there is a limited amount of evidence supporting the use of psychotropic medications for its management. A systematic scoping review was conducted to assess the current literature on brain stimulation treatments for AN with comorbid MDD, with a specific focus on MDD treatment response and weight restoration. This review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and the PubMed, PsycInfo, and MEDLINE databases were searched until July 2022 using specific key words related to AN and brain stimulation treatments. A total of 373 citations were identified, and 49 treatment studies that met the inclusion criteria were included in the review. The initial evidence suggests that electroconvulsive therapy, repetitive transcranial magnetic stimulation, and deep-brain stimulation may be effective in managing comorbid MDD in AN. Emerging evidence suggests that transcranial direct current stimulation may have a positive effect on body mass index in individuals with severe to extreme AN. However, there is a need for the development of better measurement techniques for assessing the severity of depression in the context of AN. Controlled trials that are adequately designed to account for these limitations are highly warranted for deep-brain stimulation, electroconvulsive therapy, and repetitive transcranial magnetic stimulation and hold promise for providing clinically meaningful results.

- Objectives: Updated international guideline recommendations for AN inpatient care rely on expert opinions/observational evidence and promote extended inpatient stays, warranting investigation using higher-level ecological evidence.Methods: The study was conducted according to Guidelines for Accurate and Transparent Health Estimates Reporting (GATHER). Data encompassing 13,885 ED inpatients (5336 adolescents and 8549 adults) was retrieved from Swedish public health registries. Variables analyzed included (1) ED inpatient care opportunities, (2) unique number of ED inpatients and (3) mean length of ED-related inpatient stays in age groups 15–19 and 20–88+, across 1998–2020.Results: Mean length of inpatient stays was inversely correlated to relapse to ED-related inpatient care within the same year (p < 0.001, R-squaredadj = 0.5216 and p < 0.00001, R-squaredadj = 0.5090, in the 15–19 and 20–88+ age groups, respectively), independent of number of ED inpatients treated within a year in both age groups. Extending mean adolescent inpatient duration from 35 to 45 days was associated with a ∼30% reduction in the year-wise relapse rate.Conclusions: Mean length of ED-related inpatient treatment stays was associated with reduced relapses to inpatient care within the same year, which could be interpreted as support for recommendations to include a stabilization phase in inpatient ED treatment.

Tidskriftsartikel (refereegranskat)abstract
- PURPOSE: To quantitatively and qualitatively evaluate the water-signal performance of the consistent intensity inhomogeneity correction (CIIC) method to correct for intensity inhomogeneitiesMETHODS: Water-fat volumes were acquired using 1.5 Tesla (T) and 3.0T symmetrically sampled 2-point Dixon three-dimensional MRI. Two datasets: (i) 10 muscle tissue regions of interest (ROIs) from 10 subjects acquired with both 1.5T and 3.0T whole-body MRI. (ii) Seven liver tissue ROIs from 36 patients imaged using 1.5T MRI at six time points after Gd-EOB-DTPA injection. The performance of CIIC was evaluated quantitatively by analyzing its impact on the dispersion and bias of the water image ROI intensities, and qualitatively using side-by-side image comparisons.RESULTS: CIIC significantly ( P1.5T≤2.3×10-4,P3.0T≤1.0×10-6) decreased the nonphysiological intensity variance while preserving the average intensity levels. The side-by-side comparisons showed improved intensity consistency ( Pint≤10-6) while not introducing artifacts ( Part=0.024) nor changed appearances ( Papp≤10-6).CONCLUSION: CIIC improves the spatiotemporal intensity consistency in regions of a homogenous tissue type.

- There is a long-lasting debate in ecology on cyclicity, synchrony and time lags of lemming population fluctuations. We have analysed 137 yr of previously published population data on the Norwegian lemming Lemmus lemmus in ten geographic regions of Fennoscandia. The dominating pattern was synchronous 4-yr cycles. There was no support for the hypothesis of a north-south gradient in cycle length. However. we found periods of prolonged interruptions in the cyclicity, which were more common in northern areas. Wa found a high degree of synchrony between regions. with only a weak relationship to distance, The observed pattern in lemming population dynamics was more consistent with effects from extrinsic factors, such as climate. than intrinsic factors. such as dispersal.

Tidskriftsartikel (refereegranskat)abstract
- This paper concerns the regional growth pattern in Sweden, and the purpose is to analyse what factors determine the growth rate of average income and the net migration at the regional level. We find a negative relationship between the initial level of regional average income and subsequent income growth. The results also imply that the initial endowment of human capital (measured as the percentage of the population with higher education) has a positive effect on the subsequent net migration. Other determinants of regional income growth and population movements are 'fixed endowments' (related to geography and climate) and regional labour market characteristics.

Tidskriftsartikel (refereegranskat)abstract
- This paper studies the hypothesis that local (municipal) expenditures in part can be explained by the expenditures of the regional (county) government. To accomplish this task, we derive and estimate a model of local public (municipal) spending that is defined conditional on the level of regional public expenditures. The empirical analysis is based on panel data from the Swedish local public sector for the time period 1981–1986. Among the results, we find that the hypothesis that regional expenditures are weakly separable from local expenditures can be rejected. However, we cannot reject the hypothesis that the regional expenditures are weakly exogenous in the local expenditure equation.

A novel software defined research receiver architecture
- 2009
-
Ingår i: Proceedings of the 13th IAIN World Congress. - : Nordic Institute of Navigation.
-
Konferensbidrag (refereegranskat)abstract
- Software defined receivers (SDR) are an increasingly important tool within the GNSS research community as the high level of flexibility offer a significant advantage over traditional hardware implementations. Over the last decade, software receivers have been used to investigate techniques as diverse as bi-static radar (additional correlators), multipath mitigation techniques, GPS/INS integration and array processing.Mentioned above are only a few examples of features that could be required of an SDR, other include support for new signals (Galileo, GPS L5), multiple data file formats, high sensitivity and support for very long data sets. The large number of available features should ideally be coupled with program simplicity (such that other people can understand the program) and efficiency. This paper discusses these issues and proposes several solutions such asgeneralized data buffers (that is trivial to extend for new data formats) and a unified tracking structure (regardless of signal modulation). Examples are given using a Matlab implementation based on the Borre/Akos book Ä Software-Defined GPS and Galileo Receiver", however with significant modifications. Where critical, Java is used to increase performance while maintaining cross platform compatibility. Near real-time operation is available under optimal circumstances and the receiver currently supports GPS C/A- and GPS P-code signals.

Post-processing dynamic GNSS antenna array calibration and deterministic beamforming
- 2008
-
Ingår i: Proceedings of the 21th International Technical Meeting of the Satellite Division of the Institute of Navigation. ; , s. 1311-1319
-
Konferensbidrag (refereegranskat)abstract
- An array processing GNSS (Global Navigation Satellite System) receiver may provide increased accuracy, reliability and integrity by forming beams towards satellites and nulls towards interference or reflective surfaces. Also, software defined receivers have proven themselves versatile and provide a convenient environment to implement novel algorithms.This paper first describes the gain/phase calibration of a seven element custom array antenna and proceeds to compare the single antenna performance to that of the performance attained by forming beams towards the satellites. IF (Intermediate Frequency) data, high rate samples representing the received signal in a narrow band around the GPS L1 frequency, from an array antenna have been recorded both in an environment with open sky conditions and also in more challenging areas (central Boulder, Colorado). Simultaneously, data from a high quality GPS based INS was recorded in order to obtain accurate estimates of position/ orientation. Calibration of the system (including antennas and front-ends) was performed using data from the benign environment, and based on this information, deterministic beams were formed towards the satellites using data from the semi-urban dataset. The single antenna accuracy was then compared to the position obtained by processing after forming beams.

The S.A.R.E.K Simulation Environment : Technical description of a flexible training environment for prehospital care
- 2017
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This report contains a technical description of the result of the S.A.R.E.K (Simulation – Ambulance – Research – Education - Kinship) collaboration project and the Sim2020 project. The projects are collaborations between researchers in healthcare and IT, and prehospital care practitioners, with the aim to design, develop and test a contextualized simulation environment for prehospital care. We built a simulation environment representing the full depth and width of a prehospital care process. Breadth refers to including all phases of a prehospital mission, from dispatch to handover; while depth refers to detailed representations and recreation of artefacts, information and context for each of these phases. This report outlines the details of the overall design, all equipment and practical solutions used to create this. Apart from the installation which is described in this report we have also developed methods and carried out a variety of tests and experiments which are reported elsewhere. The focus of this report is the system and its components.

Tidskriftsartikel (refereegranskat)abstract
- This article proposes a Bayesian procedure to calculate posterior probabilities of active effects for unreplicated two-level factorials. The results from a literature survey are used to specify individual prior probabilities for the activity of effects and the posterior probabilities are then calculated in a three-step procedure where the principles of effects sparsity, hierarchy, and heredity are successively considered. We illustrate our approach by reanalyzing experiments found in the literature.

The effects of PACS on radiographer’s work practice
- 2007
-
Ingår i: Radiography. - London : W.B. Saunders Co. Ltd.. ; 13:3, s. 235-240
-
Tidskriftsartikel (refereegranskat)abstract
- This paper identifies and analyses the effects of picture archiving and communica- tion systems (PACS) on radiographers’ work practice. It shows that the introduction of PACS did not simply entail the transfer of data and information from the analogue world to the digital world, but it also led to the introduction of new ways of communicating, and new activities and responsibilities on the part of radiography staff. Radiographers are called upon to work increasingly independently, and individual practitioners require higher levels of professional expertise. In all, this paper demonstrates that new technical solutions sometimes lead to sub- stantial changes in responsibilities in work. In this example, the radiographers’ work practice has become more highly scientific and they are enjoying a higher level of prestige.
