    Resilience and the temporal dimension: the chimera of timely response2017Inngår i: Theoretical Issues in Ergonomics Science, ISSN 1463-922X, E-ISSN 1464-536X, Vol. 18, nr 2, s. 110-127Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper presents a framework for reasoning about ‘timely response’, and control versus the temporal organisation of a controlling system. By three empirical examples, we show how a controlling system can be described in terms of perception points, decision points and action points. Our conclusions are that (1) temporal expectancies shape our ability to exercise control at least as much our ability to understand relations and causality, but temporality is rarely part of approaches to modelling human or system performance, (2) temporal organisation of activities shape our ability to exercise control, (3) by utilising the temporal control framework, we can describe important properties of the temporal organisation of a socio-technical system, and (4) the capacity of modelling is limited to what can be known or imagined. Therefore, models describing resilience or stability should include temporality and be based on frameworks generic enough to be applied to a wide variety of situations.

    Navigation support for dismounted soldiers using minimal information as a supplement to a digital map2015Inngår i: International Journal of Information Systems for Crisis Response and Management, ISSN 1937-9390, E-ISSN 1937-9420, Vol. 7, nr 3, s. 61-79Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    By presenting continuously updated heading and distance information on a small head-mounted display, as a supplement to a GPS-receiver, the authors examined if workload could be reduced and performance increased when navigating in a demanding situation. The purpose was to present as limited, but sufficient, information as possible to facilitate navigation. The technique was tested on ground troops, but could also be used by rescue services and police in situations that require navigation in unknown environments. The main findings were that the workload was reduced in two aspects (during navigation and handling personal equipment) but increased in another (looking for foot placement). When using the head mounted display, it was found that participants stopped fewer times to look at the GPS-receiver if they had continuous updated heading and distance information. This suggests that a supplement with minimal information on a head mounted display could be useful when navigating with a GPS-receiver in an unknown environment.

    Exploring the driver instructor metaphor: Requirement assessment for an advanced driver assistance system thatprovides driving related feedback2015Independent thesis Advanced level (degree of Master (Two Years)), 300 hpOppgave
    Abstract [en]

    The risk of being involved in a traffic car accident increases with age. Countermeasuressuch as advanced driver assistance system and retraining programs have both been waysof trying to reverse this trend. This thesis sought to merge the two countermeasures byexploring the idea of a system that gives feedback on elders' driving. Two separaterequirement assessments were carried out with the aims to address what, when and howfeedback should be communicated to elderly drivers. Additional aims were to assessrequirements that could affect the acceptance and trust in relation to the system. Firstly,a literature review assessed requirements based on preexisting knowledge in relevantdomains. Secondly, focus group interviews with driver instructors and elderly drivers wereperformed to assess requirements in relation to the specific system idea. The resultsreveal several requirements that could serve as input to the design of the system. Theresults and their possible implications are discussed.

    Arbitrarily Applicable Relational Responding in NARS2019Inngår i: NARS AGI 2019 Workshop, 2019Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In a previous publication, we argued why the behavioral psychology theory Relational Frame Theory (RFT) might be interesting for AGI researchers. This paper explores details of RFT in NARS. More specifically, we investigate different response patterns, such as equivalence, opposition, and comparison in NARS. An additional core feature of RFT is transformation of stimulus function which explains how arbitrary symbols can acquire various functions depending on the relational networks in operation. We demonstrate how NARS handles this process. Finally, future applied and basic research opportunities are discussed.

    Computerized psychological interventions and functional programming2015Inngår i: Abstracts from the 7th Swedish Congress on internet interventions (SWEsrii), Linköping: Linköping University Press , 2015, p16, Linköping, 2015Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Functional programming is an idea in computer science on how to design and evaluate computer programs in a way similar to mathematical functions. In my talk, I will argue why this way of designing programs is highly useful for the task of constructing computerized psychological interventions, and how this might help us with future challenges for the field. A demonstration will be carried out.

    Using Clojure to provide computerized psychotherapy2016Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Mental illness is a massive problem in the world today. People prefer psychological treatments over medication but access to psychotherapy is severly limited. One solution to this problem is to develop self-help treatments that can be delivered through the Internet. Research has shown that these treatments are effective and if therapist support by for example email is added, the effect could be on par with regular psychotherapy. However, therapist-supported computerized psychological treatments are very hard to access outside of research settings.

    We are a team of psychologists and psychotherapy researchers that aims to build a web application that takes advantage of modern web technologies and that could provide high-quality computerized psychotherapy at large scale. One of us had an experience with Common Lisp and from there we found Clojure. After digging into the language we found out that developing web applications with Clojure was a pure delight.

    In this talk we will describe the domain of computerized psychotherapy and some of its challenges. We will argue why we believe that Clojure is a perfect fit for developing web applications for psychotherapy. Our own experiences this far of using Clojure in this context will be described. Finally, we will discuss how we believe Clojure and its eco-system could help out even further in reducing the heavy burden of mental illness in society.

    Robert Johansson, PhD, is a licensed psychologist and a researcher at the Karolinska Institute, Stockholm Sweden. Since 2009, he has conducted research on computerized psychotherapy. He had some basic training in Common Lisp from the late 1990’s and through that learned about Clojure in late 2014. Since then, he has practiced Clojure with the aim of building web applications for providing computerized psychotherapy.

    Writing the code for ICBT web applications2016Inngår i: EABCT 2016 Abstract Book: Total Awareness, The European Association for Behavioural and Cognitive Therapies , 2016: A technical demonstration of the development process, 2016Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Scientific background:The Internet has become a cornerstone of CBT during the last 15 years. Internet-delivered CBT (ICBT) has gained a substantial evidence base with well beyond 100 randomized controlled trials supporting its efficacy.

    ICBT requires not only treatment material suitable for delivery through the Internet (for example in the form of self-help texts). A web application is also required that for example enables functionality for communication, delivery of treatment content and the possibility to collect assessments in self-report format. Many clinics and clinicians do not have access to such a treatment application and hence cannot provide ICBT even if they have access to treatment material and clinical expertise.

    While several web-based solutions for treatment delivery exist, we seldom talk about the actual development process of these applications. For many people, the task of developing a web-based ICBT treatment application can look like a massive challenge. While the task requires some basic knowledge about programming and web technologies, it is far easier than one can think.

    A key for this process to work is to use a programming language that provides expressive power, high performance, and that is possible to integrate with modern web technologies. In this demonstration we will use a programming language called Clojure that has become increasingly popular during the last years. The language is easy to learn and has a large eco-system of freely available libraries that makes the process of developing a web application similar to LEGO construction.

    During the talk, the workshop leader will show with actual programming code, how to construct a fully functional web-based application for ICBT treatment delivery. The system constructed during the talk will include different views for therapists and clients, access right management, encryption, database connection, logging, the possibility to automatically summarize collected self-report data, automatic change of presentation for smartphones and tablets, etc. Throughout the workshop, every step will be explained in detail.

    Key learning objectives:- Understand which web technologies are required for building an ICBT web application- Take part of a demonstration of important steps in the development process of web-based ICBT treatment applications- Understand the benefits of using the programming language Clojure for this task- Gain knowledge on how to go further with an interest in developing your own ICBT web application

    Implications for everyday clinical practice of CBT:The Internet has become a key modality for the clinical practice of CBT. However, outside of research settings, there exist few options for clinicians to use the Internet to communicate with their clients, to provide treatment material and to collect self-report data. This workshop will show how it is possible to develop web applications for ICBT with only a basic skill-set in programming and web technologies.

    Description of the workshop leader:Robert Johansson completed his PhD in clinical psychology from Linköping University in 2013. His research has mainly focused on developing and evaluating Internet-based treatments for depression. Besides ICBT research, he has conducted several studies on Internet-delivered psychodynamic psychotherapy and also research about the effectiveness and working mechanisms of a form of psychotherapy called Intensive Short-term Dynamic Psychotherapy. During the last years, he has developed an interest in the construction of software relevant for clinical psychology research and practice. He is currently working as a postdoc researcher in Research Group Kaldo, Karolinska Institute, Stockholm, Sweden.

    Consider Clojure: A modern Lisp that runs on Java and Javascript hosts2016Inngår i: Proceedings of the 12'th SweCog Conference / [ed] [ed] Alexander Almér, Robert Lowe, Erik Billing, Skövde: University of Skövde , 2016Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    Developing software is a key methodology in cognitive science. Lisp is a family of programming languages that historically has been very influential in cognitive science in general and in the field of artificial intelligence in particular. Scientists and practitioners alike were drawn to Lisp due to its intelligent design and elegance. However, for various reasons it has become more and more uncommon to use Lisp in cognitive science and AI research.

    Clojure is a modern Lisp language that compiles both to the Java virtual machine and to Javascript. This enables us to write fast, stand-alone applications in Lisp that runs on computers, smartphones and in web browsers - everything written in the same language. Clojure encourages functional programming – an approach to software development in where we model our application in terms of data flowing through the system. The design and implementation of an application then become a process where the developer writes modular parts that transforms data. Such workflow open up for very elegant solutions to some of today's problems in software development in general and in the field of web applications in particular.

    Clojure can be used for everything from resource-intensive server-side applications to lightweight applications that runs in the browser or as a smartphone application. In addition, Clojure has a rich eco-system of freely available libraries to make development become like building things with LEGO.

    In this talk, we will give a technical demonstration of the language in where we demonstrate various aspects of the language that is relevant for cognitive science researchers and practitioners. We will also demonstrate an e- Health application that has been written in Clojure. It enables clinical practitioners to use the Internet to provide psychological treatment to individuals with for example depression and anxiety. Our experiences with Clojure in developing this application will be described. We have also made efforts to teach software development with Clojure to clinical psychologists to enable them to write e-Health web applications without any background in software development. This project will also be described in the talk.

    We believe that Clojure combines the best of both worlds – elegance and performance. With this talk, we hope to demonstrate why we believe Clojure is a perfect fit for both research and practice in the field of cognitive science.

    An abstract specification of ICBT2016Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Background: ICBT started out as delivering self-help modules via a computer and/or the Internet, with or without additional therapist support. Today, ICBT is a broad class of services that may or may not include components such as interactive treatment content, text messaging, video communication, intelligent adaptation of content, data collection from external hardware such as wristbands, etc. There is a current lack of coherence in describing these services and their components. This lack of standards makes it impossible for services to communicate with each other, unless they were explicitly designed for this.

    Method and Results: We believe that one way to address this problem is to reason about ICBT services on an abstract level. In this talk, we will describe how we created an abstract specification of an existing guided self-help ICBT service and how we implemented this specification as an application programming interface (API). This enabled us to develop several different front ends that each could communicate with the ICBT service through the API. In addition, we will describe how one of our front end applications could be used for two different ICBT services, once these services were designed to communicate through one standardized API.

    Discussion: ICBT is evolving and could be even more integrated with external services and hardware. We believe that reasoning about ICBT on an abstract level and implementing functionality through APIs will help ICBT to develop even further.

    Automatic Extraction of Synonyms from an Easy-to-Read Corpus2016Inngår i: Proceedings of the Sixth Swedish Language Technology Conference, 2016Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper presents two novel methods aimed at extracting comprehensible synonyms to regular words, as a step towards automatic text simplification. The methods are inspired by previous work on synonym extraction and make use of bilingual dictionaries, as well as distributional semantic similarity between words. Human layman knowledge was used to evaluate the synonym candidates extracted by the methods, which proved to be perceived as synonymous to a high degree. Both methods showed promising results and qualities, and have potential to be used to further improve automatic text simplification.

    Short simulation exercises to improve emergency department nurses self-efficacy for initial disaster management: Controlled before and after study2017Inngår i: Nurse Education Today, ISSN 0260-6917, E-ISSN 1532-2793, Vol. 55, s. 20-25Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Introduction: Head nurses at emergency departments often assume responsibility for managing the initial response to a major incident, and to create surge capacity. Training is essential to enable these nurses to perform an effective disaster response. Evaluating the effects of such training is however complicated as real skill only can be demonstrated during a real major incident. Self-efficacy has been proposed as an alternative measure of training effectiveness. Purpose: The aim of this study was to examine if short, small-scale computer-based simulation exercises could improve head emergency nurses general and specific self-efficacy and initial incident management skills. Method: A within-group pretest-posttest design was used to examine 13 head nurses general and specific self efficacy before and after an intervention consisting of three short computer based simulation exercises during a 1-h session. Management skills were assessed using the computer simulation tool DigEmergo. Results: The exercises increased the head nurses general self-efficacy but not their specific self-efficacy. After completing the first two exercises they also exhibited improved management skills as indicated by shorter time to treatment for both trauma and in-hospital patients. Conclusion: This study indicates that short computer based simulation exercises provide opportunities for head nurses to improve management skills and increase their general self-efficacy.

    FUMO: En analys av det nuvarande gränssnittet samt design och utvärdering av ett designförslag2018Independent thesis Basic level (degree of Bachelor), 12 poäng / 18 hpOppgave
    Abstract [en]

    AB Realisator Robotics has developed a robot for aiding the work of the emergency services – FUMO. The interface from which the operator gets feedback from the robot is not adapted to either displays nor the target group today, since the primary focus has been to develop the robot itself instead of its interface. This study aimed to evaluate the existing interface of the robot FUMO with focus on the information presented, as well as develop a new interface oriented towards the target group. The evaluation of the current interface revealed several issues, primarily with the interpretation of the information and the layout of the interface. This initial evaluation provided a basis when creating a prototype with a more dynamic interface. The evaluation of the prototype led to a more positive response, as well as a better understanding of the information presented.

    Driving with a Speech Interaction System: Effect of Personality on Performance and Attitude of Driver2014Inngår i: HUMAN-COMPUTER INTERACTION: ADVANCED INTERACTION MODALITIES AND TECHNIQUES, PT II, SPRINGER-VERLAG BERLIN , 2014, Vol. 8511, s. 417-428Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Personality has a huge effect on how we communicate and interact with others. This study is one in a series of three that investigates how a speech based in-car system matched with dominant and submissive drivers affects performance and attitude drivers. The study was conducted with 30 participants at Linkoping University in Sweden. Data show that using a voice that combines feature from submissive and dominant speech patterns work well for both dominant and submissive drivers. The voice showed the same performance gain as when matching car voice personality with personality of driver, without the negative attitude ratings associated with the submissive car voice found in previous studies. Drivers assessment of the car system show that even though both dominant and submissive drivers find the system helpful, dominant drivers find the system more annoying and more likely to turn the system off. Design implications of in-vehicle systems are discussed.

    I Can’t Hear You? Driver’s Interacting with Male or Female Voices in Native or Non-Native Language2011Inngår i: Universal Access in Human-Computer Interaction. Context Diversity, Part III, Springer Berlin/Heidelberg, 2011, s. 298-305Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Many vehicles today are equipped with navigation systems, and all of these systems use speech or a combination of speech and graphics to provide drivers with directions to their destinations. This study investigates the effect of gender of voice when providing driving instructions in English to drivers that are non-native speakers of English. In a 2(native/non-native) by 2(gender of voice) between participant study, 40 participants in age group 18-25 drove in a driving simulator for 25 minutes with navigation information system that gave drivers directions to a set destination. Results show that gender of voice did not affect native English speaking drivers. For non-native speakers, however, a female voice worked better for both female and male drivers. Non-native speakers consistently missed to act on navigational information give by the male voice. Design implications for voice systems are discussed.

    Impact of Voice Variation in Speech-Based In-Vehicle Systems on Attitude and Driving Behavior2009Inngår i: Human Factors and Ergonomics Society Europe Chapter (HFES), 2009Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Automobile manufacturers are making information systems available in all vehicles. Mostsystems are screen based, but increasingly systems are either hybrids (screen/speech) orspeech based. Speech systems in vehicles may have advantages over screen based in-vehiclesystems; literature suggests that speech can be less distracting than screen-based interactions.Nonetheless, using speech systems in the car also introduces social and attitudinal effects.Voices are not neutral! Voices carry socio-economic cues including indicators of gender, age,personality, emotional state, ethniticity, education and social status. Perception ofinformation presented by the voice is influenced by the perception of the voice demographics.This is further complicated by different individuals perceiving voices in different ways. A voicethat is seen as positive by one individual can be perceived negatively by another. We presentresults from a number of driving simulator studies of speech based in-vehicle systems. These studiesshow that speech based in-vehicle systems can affect drivers’ attitude and drivingperformance. Attitude and performance can be improved, but the effect of the voice can also proveharmful for driving behaviour and driving safety. This makes it important to include the voice as adesign parameter of speech-based in-vehicle systems.

    The effects of different voices for speech-based in-vehicle interfaces: Impact of young and old voices on driving performance and attitude2009Inngår i: Proceedings of the 10th Annual Conference of the International Speech Communication Association, INTERSPEECH 2009, 2009, s. 2795-2798Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper investigates how matching age of driver with age of voice in a conversational in-vehicle information system affects attitudes and performance. 36 participants from age groups, 55 -75 and 18 - 25, interacted with a conversational system with young or old voice in a driving simulator. Results show that all drivers rather communicated with a young than old voice in the car. This willingness to communicate had a detrimental effect on driving performance. It is hence important to carefully select voices, since voice properties can have enormous effects on driving safety. Clearly, one voice doesnt fit all.

    An explorative study of the technology transfer coach as a preliminary for the design of a computer aid2014Independent thesis Advanced level (degree of Master (One Year)), 20 poäng / 30 hpOppgave
    Abstract [en]

    The university technology transfer coach has an important role in supporting the commercialization of research results. This thesis has studied the technology transfer coach and their needs in the coaching process. The goal has been to investigate information needs of the technology transfer coach as a preliminary for the design of computer aids.Using a grounded theory approach, we interviewed 17 coaches working in the Swedish technology transfer environment. Extracted quotes from interviews were openly coded and categorized. The analysis show three main problem areas related to the information needs of the technology transfer coach; awareness, communication, and resources. Moreover, 20 features for future computer aids were extracted from the interview data and scenarios and personas where developed to exemplify the future use of computer aids.We conclude that there is a need for computer support in the coaching process. Such systems should aid the coach in; awareness, aiding the coach to focus on meetings; communication, aid the coach to transfer commercialisation knowledge; and resources, aid the coach in accessing and delivering of resources to the coachee. However, it is imperative that the computer aids do not interfere with the coach current process; and that the computer aid is not seen as the sole solution.

    A Component based Approach to Measuring Text Complexity2018Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    We present results from assessing text complexity based on a factorisation of text property measures into components. The components are evaluated by investigating their ability to classify texts belonging to different genres. Our results show that the text complexity components correctly classify texts belonging to specific genres, given that the genres adhere to certain textual conventions. We also propose a radar chart visualisation to communicate component based text complexity.

    T-MASTER -- A tool for assessing students' reading abilities2015Inngår i: Proceedings of the 7th International Conference on Computer Supported Education (CSEDU 2015), Lisbon, Portugal, SciTePress, 2015, s. 220-227Konferansepaper (Fagfellevurdert)
    Abstract [en]

    We present T-MASTER, a tool for assessing students’ reading skills on a variety of dimensions. T-MASTER uses sophisticated measures for assessing a student’s reading comprehension and vocabulary understanding. Texts are selected based on their difficulty using novel readability measures and tests are created based on the texts. The results are analyzed in T-MASTER, and the numerical results are mapped to textual descriptions that describe the student’s reading abilities on the dimensions being analysed. These results are presented to the teacher in a form that is easily comprehensible, and lends itself to inspection of each individual student’s results.

    Visualization of infectious disease outbreaks in routine practice2013Inngår i: Studies in Health Technology and Informatics, ISSN 0926-9630, E-ISSN 1879-8365, Vol. 192, s. 697-701Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Throughout the history of epidemiology, visualizations have been used as the interface between public-health professionals and epidemiological data. The aim of this study was to examine the impact of the level of abstraction when using visualizations on routine infectious disease control. We developed three interactive visualization prototypes at increasing levels of abstraction to communicate subsets of influenza outbreak surveillance information. The visualizations were assessed through workshops in an exploratory evaluation with infectious disease epidemiologists. The results show that despite the potential of processed, abstract, and information-dense representations, increased levels of abstraction decreased epidemiologists understanding and confidence in visualizations. Highly abstract representations were deemed not applicable in routine practice without training. Infectious disease epidemiologists work routines and decision-making need to be further studied in order to develop visualizations that meet both the quality requirements imposed by policy-makers and the contextual nature of work practice.

    Electronic data capture on athletes pre-participation health and in-competition injury and illness at major sports championships: An extended usability study in Athletics2018Inngår i: Health Informatics Journal, ISSN 1460-4582, E-ISSN 1741-2811, Vol. 24, nr 2, s. 136-145Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study set out to identify factors critical for the usability of electronic data collection in association with championships in individual sports. A qualitative analysis of electronic data collection system usability for collection of data on pre-participation health from athletes and in-competition injury and illness from team physicians was performed during the 2013 European Athletics Indoor Championships. A total of 15 athletes and team physicians participated. Athletes were found to experience few problems interacting with the electronic data collection system, but reported concerns about having to reflect on injury and illness before competitions and the medical terminology used. Team physicians encountered problems when first navigating through the module for clinical reporting, but they were not subjected to motivational problems. We conclude that athletes motivation to self-report health data and the design of the human-computer interface for team physicians are key issues for the usability of electronic data collection systems in association with championships in individual sports.

    Internet of Things – Does Particle Photon rely too much on its own cloud solution?2017Independent thesis Basic level (degree of Bachelor), 10,5 poäng / 16 hpOppgave
    Abstract [en]

    Internet of Things is rapidly growing and there are many devices and cloud solutions on the market. This thesis addresses the usage of Particle Photon alongside Microsoft Azure and intends to determine its suitability as an IoT solution. Particle Photon is bundled with Particle Cloud which is a comprehensive solution that makes IoT simple, swift and cheap – but how good is the device if the service ceases to exist? To determine this dependency and its overall IoT suitability, tests were performed to measure transmission limitations as well as reliability both with and without the included cloud service. In addition, the research method includes a Microsoft Azure implementation. The results show that Particle Photon and Microsoft Azure makes a great IoT solution, with or without its own cloud solution – even though most of the ease-of-use and benefits comes from the cloud service. Using Particle Cloud alongside Particle Photon and Microsoft Azure reduces transmission time and increases reliability compared to only using Particle Photon.

    Läkemedelshantering: En teoretisk studie i hur man kan minska antalet felmedicineringar i Sverige2012Independent thesis Basic level (degree of Bachelor), 12 poäng / 18 hpOppgave
    Abstract [sv]

    Denna uppsats är en studie i hur man hanterar läkemedel på en klinik på ett sjukhus i Sverige. Målet är att se vilka åtgärder som skulle kunna appliceras för att få en säkrare vård genom att försöka minska antalet felmedicineringar. Studien gjordes genom observationer och samtal med anställda på kliniken, samt att relevanta teorier hittades, vilket gjorde att en del förbättringsförslag och idéer till vidare forskning lades fram. Resultaten är till exempel hur man skulle kunna minska antalet felmedicineringar genom att ta bort ett antal säkerhetsåtgärder. Detta anses kunna göras genom att flytta runt läkemedel i läkemedelsförråden utan att förvarna personalen (förutsatt att personalen vet att det kan hända utan förvarning innan det nya systemet används). Att göra på det viset skulle i teorin innebära att sjuksköterskorna skulle behöva vara mer uppmärksamma i mycket högre grad än förut eftersom läkemedel inte längre står där det brukar stå. Ytterligare resultat är till exempel hur läkemedelsföretagen skulle kunna illustrera ett läkemedels styrka genom färgkoder på kartonger och pillerkartor eftersom det inte finns någon nationell standard för det idag, vilket ha lett till att alla företag har sitt eget sätt att illustrera detta på, om de har något alls. Även mer specifika resultat som eventuellt endast kan appliceras på ett mindre antal kliniker och avdelningar har lagts fram.

    Using WebGL to create TV-centric user interfaces2014Independent thesis Basic level (degree of Bachelor), 10,5 poäng / 16 hpOppgave
    Abstract [en]

    In recent years the user interfaces of the TV platform have been powered by HTML, but since the platform is starting to support new techniques it might be time to change the focus. HTML is a good choice for interface development because of its high level and platform independence; however, when performance is critical and the requirements are high HTML can impose serious restrictions. WebGL is a technology released in 2011 that brings a low-level graphics API to the web. The API allows for development of advanced 3D graphics and visual effects that were impossible or impractical in the HTML world. The problem is that the hassle of using pure WebGL is in most cases too big to overcome. In this thesis a proof-of-concept was developed to investigate the issues and limitations of WebGL. A conclusion was made that even though the performance was not as good as expected it might still be viable for use in some settings.

    A clinical decision support tool for improving adherence to guidelines on anticoagulant therapy in patients with atrial fibrillation at risk of stroke: A cluster-randomized trial in a Swedish primary care setting (the CDS-AF study)2018Inngår i: PLoS Medicine, ISSN 1549-1277, E-ISSN 1549-1676, Vol. 15, nr 3, artikkel-id e1002528Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background

    Atrial fibrillation (AF) is associated with substantial morbidity, in particular stroke. Despite good evidence for the reduction of stroke risk with anticoagulant therapy, there remains significant undertreatment. The main aim of the current study was to investigate whether a clinical decision support tool (CDS) for stroke prevention integrated in the electronic health record could improve adherence to guidelines for stroke prevention in patients with AF.

    Methods and findings

    We conducted a cluster-randomized trial where all 43 primary care clinics in the county of Östergötland, Sweden (population 444,347), were randomized to be part of the CDS intervention or to serve as controls. The CDS produced an alert for physicians responsible for patients with AF and at increased risk for thromboembolism (according to the CHA2DS2-VASc algorithm) without anticoagulant therapy. The primary endpoint was adherence to guidelines after 1 year. After randomization, there were 22 and 21 primary care clinics in the CDS and control groups, respectively. There were no significant differences in baseline adherence to guidelines regarding anticoagulant therapy between the 2 groups (CDS group 70.3% [5,186/7,370; 95% CI 62.9%–77.7%], control group 70.0% [4,187/6,009; 95% CI 60.4%–79.6%], p = 0.83). After 12 months, analysis with linear regression with adjustment for primary care clinic size and adherence to guidelines at baseline revealed a significant increase in guideline adherence in the CDS (73.0%, 95% CI 64.6%–81.4%) versus the control group (71.2%, 95% CI 60.8%–81.6%, p = 0.013, with a treatment effect estimate of 0.016 [95% CI 0.003–0.028]; number of patients with AF included in the final analysis 8,292 and 6,508 in the CDS and control group, respectively). Over the study period, there was no difference in the incidence of stroke, transient ischemic attack, or systemic thromboembolism in the CDS group versus the control group (49 [95% CI 43–55] per 1,000 patients with AF in the CDS group compared to 47 [95% CI 39–55] per 1,000 patients with AF in the control group, p = 0.64). Regarding safety, the CDS group had a lower incidence of significant bleeding, with events in 12 (95% CI 9–15) per 1,000 patients with AF compared to 16 (95% CI 12–20) per 1,000 patients with AF in the control group (p = 0.04). Limitations of the study design include that the analysis was carried out in a catchment area with a high baseline adherence rate, and issues regarding reproducibility to other regions.

    Conclusions

    The present study demonstrates that a CDS can increase guideline adherence for anticoagulant therapy in patients with AF. Even though the observed difference was small, this is the first randomized study to our knowledge indicating beneficial effects with a CDS in patients with AF.

    Clinical decision support for stroke prevention in atrial fibrillation (CDS-AF): Rationale and design of a cluster randomized trial in the primary care setting2017Inngår i: American Heart Journal, ISSN 0002-8703, E-ISSN 1097-6744, Vol. 187, s. 45-52Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background Atrial fibrillation (AF) is associated with substantial morbidity, in particular stroke. Despite good evidence for the reduction of stroke risk with anticoagulant therapy, there remains a significant undertreatment. The main aim of the current study is to investigate whethera clinical decision support tool for stroke prevention (CDS) integrated in the electronic health record can improve adherence to guidelines for stroke prevention in patients with AF. Methods We will conduct a cluster randomized trial where 43 primary care clinics in the county of Ostergotland, Sweden (population 444,347), will be randomized to be part of the CDS intervention or serve as controls. The CDS will alert responsible physicians of patients with AF and increased risk for thromboembolism according to the CHA(2)DS(2)VASc (Congestive heart failure, Hypertension, Age 74 years, Diabetes mellitus, previous Stroke/TIA/thromboembolism, Vascular disease, Age 65-74 years, Sex category (i.e. female sex)) algorithm without anticoagulant therapy. The primary end point will be adherence to guidelines after 1 year. Conclusion The present study will investigate whether a clinical decision support system integrated in an electronic health record can increase adherence to guidelines regarding anticoagulant therapy in patients with AF.

    Utvärdering av kvalitetsregistret och processtödssystemet Carath2017Independent thesis Basic level (degree of Bachelor), 12 poäng / 18 hpOppgave
    Abstract [sv]

    Studien genomförs i syfte att utvärdera hur arbetsflödet i sjukvårdssystemet Carath är anpassat efter rutiner hos användarna på de thoraxkliniker som äger systemet och där det används. Tre arbetsplatsundersökningar och elva stycken intervjuer genomfördes med sjukhuspersonal på olika kliniker i Sverige med metoden kontextuell design.

    Resultaten från studien visar att Carath är anpassat efter patientflödet på klinikerna men i mindre grad anpassat efter användares arbetsrutiner och roller. Studien visar även på att systemet saknar inbyggd hantering för återkoppling och kontroller av registrerad data. Dessa funktioner utförs istället manuellt utanför systemet. Samtliga av de saknade funktionerna bekräftas även genom SEIPS-modellen som funktioner som är rekommenderbara inom ett sjukvårdssystem. Sammantaget visar resultatet från kontextuella intervjuer med kommentarer från personal, genererade sekvensmodeller över arbetsflöden och utvärderingar mot SEIPS-modellen att Carath skulle behöva balanseras mellan patientflöde och personalens arbetsflöde. Funktioner för återkoppling och kontroll skulle integreras i systemet. Framtida arbete innefattar en undersökning kring integration mot andra system inom sjukvården.

    Semantic Complex Event Processing for Decision Support2014Inngår i: The Semantic Web – ISWC 2014: 13th International Semantic Web Conference, Riva del Garda, Italy, October 19-23, 2014. Proceedings, Part II, Springer, 2014, Vol. 8797, s. 529-536Konferansepaper (Fagfellevurdert)
    Abstract [en]

    An increasing amount of information is being made available as online streams, and streams are expected to grow in importance in a variety of domains in the coming years (e.g., natural disaster response, surveillance, monitoring of criminal activity, and military planning [7,22]). Semantic Web (SW) technologies have the potential to combine heterogeneous data sources, leveraging Linked Data principles, but traditional SW methods assume that data is more or less static, which is not the case for streams. The SW community has attempted to bring streams to a semantic level, i.e., Linked Stream Data, and a number of RDF stream processing engines have been produced [1,4,13,20]. This thesis work aims at developing and evaluating techniques for creating aggregated and layered abstractions of events. These abstractions can be used by decision makers to create better situation awareness, assisting in identifying decision opportunities, structuring and summarizing decision problems, and decreasing cognitive workload.

    Towards Semantically Enabled Complex Event Processing2017Licentiatavhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    The Semantic Web provides a framework for semantically annotating data on the web, and the Resource Description Framework (RDF) supports the integration of structured data represented in heterogeneous formats. Traditionally, the Semantic Web has focused primarily on more or less static data, but information on the web today is becoming increasingly dynamic. RDF Stream Processing (RSP) systems address this issue by adding support for streaming data and continuous query processing. To some extent, RSP systems can be used to perform complex event processing (CEP), where meaningful high-level events are generated based on low-level events from multiple sources; however, there are several challenges with respect to using RSP in this context. Event models designed to represent static event information lack several features required for CEP, and are typically not well suited for stream reasoning. The dynamic nature of streaming data also greatly complicates the development and validation of RSP queries. Therefore, reusing queries that have been prepared ahead of time is important to be able to support real-time decision-making. Additionally, there are limitations in existing RSP implementations in terms of both scalability and expressiveness, where some features required in CEP are not supported by any of the current systems. The goal of this thesis work has been to address some of these challenges and the main contributions of the thesis are: (1) an event model ontology targeted at supporting CEP; (2) a model for representing parameterized RSP queries as reusable templates; and (3) an architecture that allows RSP systems to be integrated for use in CEP. The proposed event model tackles issues specifically related to event modeling in CEP that have not been sufficiently covered by other event models, includes support for event encapsulation and event payloads, and can easily be extended to fit specific use-cases. The model for representing RSP query templates was designed as an extension to SPIN, a vocabulary that supports modeling of SPARQL queries as RDF. The extended model supports the current version of the RSP Query Language (RSP-QL) developed by the RDF Stream Processing Community Group, along with some of the most popular RSP query languages. Finally, the proposed architecture views RSP queries as individual event processing agents in a more general CEP framework. Additional event processing components can be integrated to provide support for operations that are not supported in RSP, or to provide more efficient processing for specific tasks. We demonstrate the architecture in implementations for scenarios related to traffic-incident monitoring, criminal-activity monitoring, and electronic healthcare monitoring.

    Event Object Boundaries in RDF Streams2013Inngår i: Proceedings of the 2nd International Workshop on Ordering and Reasoning, Co-located with the 12th International Semantic Web Conference (ISWC 2013), CEUR-WS , 2013, Vol. 1059, s. 37-42Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The amount of information available as online streams is increasing steadily. A number of RDF stream processing systems have been developed in an attempt to leverage existing Semantic Web technologies, and to support typical stream operations, but very little attention has been paid to the way in which event objects (i.e. data records representing events) are streamed. In this position paper, we present the issue of respecting event object boundaries in RDF streams, and discuss some pros and cons of the various solutions

    Supporting Real-Time Monitoring in Criminal Investigations2015Inngår i: SEMANTIC WEB: ESWC 2015 SATELLITE EVENTS, SPRINGER INT PUBLISHING AG , 2015, Vol. 9341, s. 82-86Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Being able to analyze information collected from streams of data, generated by different types of sensors, is becoming increasingly important in many domains. This paper presents an approach for creating a decoupled semantically enabled event processing system, which leverages existing Semantic Web technologies. By implementing the actor model, we show how we can create flexible and robust event processing systems, which can leverage different technologies in the same general workflow. We argue that in this context RSP systems can be viewed as generic systems for creating semantically enabled event processing agents. In the demonstration scenario we show how real-time monitoring can be used to support criminal intelligence analysis, and describe how the actor model can be leveraged further to support scalability.

    An Ontology for Ice Hockey2019Inngår i: ISWC 2019 Satellites: Proceedings of the ISWC 2019 Satellite Tracks (Posters & Demonstrations, Industry, and Outrageous Ideas) co-located with 18th International Semantic Web Conference (ISWC 2019), 2019, s. 13-16Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Ice hockey is a highly popular sport that has seen significant increase in the use of sport analytics. To aid in such analytics, most major leagues collect and share increasing amounts of play-by-play data and other statistics. Additionally, some websites specialize in making such data available to the public in user-friendly forms. However, these sites fail to capture the semantic information of the data, and cannot be used to support more complex data requirements. In this paper, we present the design and development of an ice hockey ontology that provides improved knowledge representation, enables intelligent search and information acquisition, and helps when using information from multiple databases. Our ontology is substantially larger than previous ice hockey ontologies (that cover only a small part of the domain) and provides a formal and explicit representation of the ice hockey domain, supports information retrieval, data reuse, and complex performance metrics.

    The effect of the visual gender of an embodied agent: A cross-cultural comparison2013Inngår i: Annual Meeting of the American Educational Research Association (AERA 2013), Washington: AERA, American Educational Research Association , 2013, s. 1-9Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    This study explored if the visual gender representations (androgynous, male, or female) of an embodied agent would influence students’ perceptions of their agent and their attitudes toward the agent as their conversational partner. The study also explored if students’ gender and cultural background would interact with the agent’s visual gender to influence their perceptions and attitudes. Participants were 208 early-teen students sampled from US and South Korea. The results revealed that student gender was a significant factor for influencing students' perceptions and attitudes and that the students showed positive attitudes toward an androgynous agent more than toward a gendered agent (either male or female).

    Cyclist efficiency and its dependence on infrastructure and usual speed2018Inngår i: Transportation Research Part F: Traffic Psychology and Behaviour, ISSN 1369-8478, E-ISSN 1873-5517, Vol. 54, s. 148-158Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Bicyclists are a heterogeneous group, with varying abilities, traffic education and experience. While efficiency was identified as an important factor on utility bicycle trips, it might be traded for experienced safety, for example by choosing different pathways in a given situation, or by relinquishing ones right of way. In a semi-controlled study with 41 participants, a grouping was made according to self-reported riding speed in relation to other cyclists. The participants cycled twice along a 3 km inner-city route, passing four intersections with different priority rules. The cyclists were free to choose how to negotiate the intersections. Speed and the traffic surroundings were recorded via gps and cameras on the bike of the participant and of a following experimenter. For each cyclist, the base speed on undisturbed segments was determined as reference. Based on this, the efficiency in different types of intersections was computed per cyclist group. It turned out that infrastructural aspects, cyclist group and the presence and behaviour of interacting traffic influenced cyclist efficiency. Faster cyclists were delayed more when the infrastructure required a stop regardless of the traffic situation, like at a red traffic light or a stop sign. The members of the so-called comfort cyclists group were delayed the most in a roundabout with mixed traffic, where many chose to get off their bike and walk. In a society working for equality of access to the transport system, it is recommended to develop solutions that consider and accommodate the behaviours of different cyclist groups when planning bicycling infrastructure.

    Adding Challenge to a Teachable Agent in a Virtual Learning Environment2016Licentiatavhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    The topic of this thesis concerns what happens when challenging behavior is added to a teachable agent in a virtual learning environment. The aim of adding challenging behavior to teachable agents is to encourage students to engage in learning behaviors, improve their motivation and engagement, which may result in a deeper level of comprehension and an improved learning experience. We conducted an explorative user study, using Guardian of History, a teachable agent learning environment in history. We analyzed data from 146 students, 11-12 years old, from a Swedish school. The students were assigned to two different agent conditions: traditional teachable agent (TA) or a challenging TA (CTA). The conditions were also balanced with respect to the students’ level of self-efficacy. The CTA exhibited the following challenging behaviors: 1) introduction of error, 2) rejection of correct facts, and 3) proposal of a higher level of difficulty. Students who used the challenging TA and also had a high level of self-efficacy performed better in the CTA condition and students with a low level of self-efficacy reached better academic achievement in the traditional TA condition. Students did not experience the learning-by-teaching effects different by the introduced challenging TA behaviors. Students within the CTA condition got better at responding to challenging TA behavior, than students in the TA condition. The CTA behavior “rejection of correct facts” was better received than the “rejection of correct”, this suggests that a challenging TA may benefit to a larger degree by questioning rather than by introducing errors.

    Introducing a challenging teachable agent2014Inngår i: Learning and Collaboration Technologies: Designing and Developing Novel Learning Experiences / [ed] Zaphiris, P; Ioannou, A, Berlin: Springer Berlin/Heidelberg, 2014, s. 53-62Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper explores the potentials of a new type of pedagogical agent – a Challenger Teachable Agent. The aim of such a pedagogical agent is to increase engagement and motivation, and challenge students into deeper learning and metacognitive reasoning. It is based on the successful implementation of the Learning by Teaching approach in Teachable Agents, and in addition it draws on previous work that has shown the potential of resistance or challenge as means to improve learning. In this paper we discuss how these two bases can be combined and realized through new types of behaviours in a Teachable Agent
