    Improving qualities of e‐government services in Rwanda: A service provider perspective2019In: The Electronic Journal of Information Systems in Developing Countries, E-ISSN 1681-4835, Vol. 85, no 5, article id e12089Article in journal (Refereed)
    Abstract [en]

    E‐government implementation is growing worldwide. In the context of developed countries, as well as some developing ones, research provides tools to evaluate e‐government services and reflect on e‐government performance. However, in the least developed countries (LDCs), where the preconditions are in many ways more challenging, little is known about those services. While information technology can be imported, social, organizational, and infrastructural arrangements conducive to high‐quality service delivery must be developed locally. In contributing to understanding the challenges as well as opportunities involved, this paper explores the qualities of e‐government services in Rwanda, an East African LDC. The investigation focuses on service providers' views of the qualities, as it is only through their understanding of the situation that service quality can be improved. This is a qualitative study based on interviews with employees of government organizations and document analysis. We identify and discuss 28 e‐government service quality factors, which are grouped into nine quality dimensions—accessibility, availability, awareness, responsiveness, information quality, information security, ease of use, support, and cost. This research contributes to raising awareness about the qualities of e‐government services in Rwanda in particular but may also have relevance for other LDCs.

    Agilt RUP / Plandrivna Agila metoder: Hur arbetar företagen?2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Inom systemutveckling används ett flertal olika arbetsmetoder. Däribland agila metoder som t.ex. XP, SCRUM, Kanban och plandrivna t.ex. RUP, Vattenfallsmodellen. Dessa kom till efter att IT-branschen upplevt en kris där det inte fanns stöd för hur utveckling bör ske. Denna rapport syftar till att se över hur företag idag använder sig utav dessa och vilka aspekter som påverkar valet av metoder, finns det konsekvenser att ta hänsyn till? Huvudfrågeställningen i undersökningen är Hur arbetar företagen i verkligheten med systemutvecklingsmetoder?

    För att ta reda på detta utfördes intervjuer hos olika systemutvecklingsföretag samt en litteraturstudie för att se över vad som redan undersökts innan. Genom intervjuerna och litteraturstudien kunde vi se en balans där varje företag har någon form utav agil tillämpning med ett visst inslag och stöd av plandrivna metoddelar. Några utav företagen har funnit Kanban som en del-lösning till utvecklingsarbetet. Det går inte att finna ett gemensamt svar på huvudfrågan för alla företag då de arbetar situations anpassat och att det inte finns några specifika standarder som de behöver förhålla sig till.

    SMSaude: design, development and implementation of a remote/mobile patient management system to improve retention in care for HIV/AIDS and tuberculosis patients2015In: Journal of Medical Internet Research, E-ISSN 1438-8871, Vol. 3, no 1, article id e26Article in journal (Refereed)
    Abstract [en]

    Background: The widespread and low cost of mobile phones and the convenience of short message service (SMS) text messaging suggest potential suitability for use with alternative strategies for supporting retention in care and adherence to the treatment of various chronic diseases, such as HIV and tuberculosis (TB). Despite the growing body of literature reporting positive outcomes of SMS text message-based communication with patients, there is yet very little research about the integration of communication technologies and electronic medical records or electronic patient tracking systems.

    Objective: To design, develop, and implement an integrated mobile phone text messaging system used to follow up with patients with HIV and TB in treatment in Mozambique.

    Methods: Following the design science research methodology, we developed a Web-based system that provides support to patients. A case study involving three health care sites in Mozambique was a basis for discussing design issues for this kind of system. We used brainstorming techniques to solicit usability requirements, focus group meetings to discuss and define system architecture, and prototyping to test in real environments and to improve the system.

    Results: We found six sets of system requirements that need to be addressed for success: data collection, telecommunication costs, privacy and data security, text message content, connectivity, and system scalability. A text messaging system was designed and implemented in three health facilities. These sites feed data into a central data repository, which can be used for analysis of operations and decision support. Based on the treatment schedule, the system automatically sent SMS text message appointment reminders, medication reminders, as well as motivational and educational messages to patients enrolled in antiretroviral therapy and TB treatment programs.

    Conclusions: We successfully defined the requirements for, designed, and implemented a mobile phone text messaging system to support HIV and TB treatments. Implementation of this system could improve patients' self-management skills and strengthen communication between patients and health care providers.

    Online shopping for women's apparel: A study extending generalization possibilities for problematic heuristics in online shopping2007Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    As an increasing number of people are logging on to the internet to do their shopping, it is imperative for a site to be accessible and usable. Nielsen’s heuristic method is one esteemed method that many web site developers use in their design work. One study suggests that online shopping needs most improvement with the heuristics “User control and freedom” where an undo button often is lacking and in ‘Help and Documentation’ where the user may not easily switch between their work and the help. The study, however, has been made on grocery shops alone.

    The following study adopts the results of the past study as hypotheses and investigates if they hold true for another type of online shopping site – women’s apparel. The results of the study confirm that these two heuristics indeed are the two most troublesome. However, for the biggest usability disaster under each, the results are either inapplicable or only lend weak support. The following results lend more support to a possible generalization for all online sites and better awareness among software developers of online shopping sites. Yet a more consistent base of common usability disasters under these two specific heuristics needs to be developed.

    Capturing semi-automated decision making: the methodology of CASADEMA2010Doctoral thesis, monograph (Other academic)
    Abstract [en]

    This thesis presents a new methodology named CASADEMA (CApturing Semi-Automated DEcision MAking) which captures the interaction between humans and the technology they use to support their decision-making within the domain of Information Fusion. We are particularly interested in characterising the interaction between human decision makers and artefacts in semi-automated fusion processes. In our investigation we found that the existing approaches are limited in their ability to capture such interactions in sufficient detail. The presented method is built upon a distributed-cognition perspective. The use of this particular theoretical framework from cognitive science enables the method to take into account not only the role of the data captured in the physical and digital artefacts of the fusion system (e.g., radar readings, information from a fax or database, a piece of paper, etc.), but also the cognitive support function of the artefacts themselves (e.g., as an external memory) as part of the fusion process. That is, the interdependencies between the fusion process and decision-making can be captured. This thesis thus contributes to two main fields. Firstly, it enables, through CASADEMA, a distributed-cognition perspective of fusion processes in the, otherwise, rather technology-oriented field of Information Fusion. This has important conceptual implications, since it views fusion processes as extending beyond the boundary of physical/computer systems, to include humans, technology, and tools, as well as the interactions between them. It is argued that a better understanding of these interactions can lead to a better design of fusion processes, making CASADEMA an important contribution to the information fusion field. Secondly, the thesis provides, again in the form of CASADEMA, a practical application of the distributed-cognition theoretical framework. Importantly, the notations and definitions introduced in CASADEMA structure the otherwise currently rather loosely defined concepts and approaches in distributed cognition research. Hence, the work presented here also contributes to the fields of cognitive science and human-computer interaction.

    The Swedish Web Version of the Quality of Recovery Scale Adapted for Use in a Mobile App: Prospective Psychometric Evaluation Study2017In: JMIR mhealth and uhealth, E-ISSN 2291-5222, Vol. 5, no 12, article id e188Article in journal (Refereed)
    Abstract [en]

    Background: The 40-item Quality of Recovery (QoR-40) questionnaire is well validated for measuring self-assessed postoperative recovery. The Swedish version of the 40-item Quality of Recovery (QoR-40) has been developed into a Web-based questionnaire, the Swedish Web version of the Quality of Recovery (SwQoR) questionnaire, adapted for use in a mobile app, Recovery Assessment by Phone Points, or RAPP.

    Objective: The aim of this study was to test the validity, reliability, responsiveness, and clinical acceptability and feasibility of SwQoR.

    Methods: We conducted a prospective psychometric evaluation study including 494 patients aged ≥18 years undergoing day surgery at 4 different day-surgery departments in Sweden. SwQoR was completed daily on postoperative days 1 to 14.

    Results: All a priori hypotheses were confirmed, supporting convergent validity. There was excellent internal consistency (Cronbach alpha range .91-.93), split-half reliability (coefficient range .87-.93), and stability (ri=.99, 95% CI .96-.99; P<.001). Cohen d effect size was 1.00, with a standardized response mean of 1.2 and a percentage change from baseline of 59.1%. An exploratory factor analysis found 5 components explaining 57.8% of the total variance. We noted a floor effect only on postoperative day 14; we found no ceiling effect.

    Conclusions: SwQoR is valid, has excellent reliability and high responsiveness, and is clinically feasible for the systematic follow-up of patients’ postoperative recovery.

    Skydd mot kopiering av mjukvara: En studie i kopieringsskydd och relaterade faktorer.2007Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Detta arbete behandlar kopieringsskydd och hur dessa fungerar. Det övergripande syftet

    med detta arbete är att analysera de nuvarande tekniker som finns inom kopieringsskydd,

    dess säkerhet och tekniska inriktning.

    Analyseringen av de nuvarande teknikerna inom kopieringsskydd och dess faktorer

    gjordes genom en litteraturstudie. Genom studien kunde man identifiera säkerheten och

    andra faktorer till varje teknik. Denna information användes sedan som grund för en

    undersökning där informationen relaterades till vilka generella faktorer som kan tänkas

    påverka valet av kopieringsskydd. Om utvecklarna påverkas av säkerhet eller om de gör

    andra val på grund av andra faktorer.

    Säkerheten som först ansågs vara den viktigaste faktorn när det kommer till skydd mot

    kopiering var i själva verket inte alls lika relevant. Istället regerade kostnaden som en stor

    faktor, tillsammans med dålig kunskap inom utvecklingen av kopieringsskydd samt dålig

    planering.

    Visuell användbarhet: Modell & riktlinjer för grafiska användargränssnitt i integrerade utvecklingsmiljöer2007Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna uppsats behandlar en undersökning avsedd att skapa verktyg för användning

    vid bedömning av utvecklingsmiljöers användargränssnitt. Undersökningen

    inleddes med en litteraturstudie där material som antingen gav information riktad

    mot hur webbsidor (vilka vi såg som besläktade med utvecklingsmiljöer ur ett

    visuellt perspektiv) och mjukvara skall göras användarvänliga ur ett visuellt

    perspektiv eller hur människor tittar på och tolkar kompositioner sammanställdes.

    Ur materialet togs riktlinjer och en modell fram som kan användas för att bedöma

    hur väl en utvecklingsmiljös gränssnitt är uppbyggt eller för att själv förändra detta

    gränssnitt utifrån egna prioriteringar av miljöns funktionalitet. Därefter testas

    verktygen på tre olika utvecklingsmiljöer. Vi fann att undersökningen och verktygen

    utgör en god grund för vidare studier, och att det test vi genomfört visar på att

    verktygen redan nu i viss mån är dugliga och användbara för att värdera grafiska

    användargränssnitt i utvecklingsmiljöer.

    Släpp kunskapen loss: det är vård!2017Collection (editor) (Other academic)
    Abstract [sv]

    Vården genomgår en transformation till följd av bl.a. grundläggande krav om jämlik och tillgänglig vård i kombination med en åldrande befolkning och ökad folkmängd. Medborgare, beslutfattare, profession och forskare är alla överens om att uppgiften är grannlaga och mycket angelägen. I den här boken lyfts innovation och digitalisering fram som medel för vårdens transformation. Innehållet i boken är baseras på följeforskning av Innovationslabbet för eHälsa, stationerat på Innovationsplatsen vid Karolinska Universitetssjukhuset, i samarbete med Karolinska Institutet. Innovationslabbet för eHälsa möjliggjordes av en Vinnova finansierad testbädd för Vårdinformatik som startade hösten 2013 och avslutades hösten 2016.

    I boken visar vi hur digital plattformsförmåga i kombination med organisatorisk innovationsförmåga är avgörande för att lyckas med digitalisering. Som läsare får du också följa 23 innovationsberättelser genom olika vårdgrenar och teknisk infrastruktur.Syftet med boken är att inspirera och bidra till kunskap om digital innovation. Boken vänder sig till dig som är intresserad av vårdens digitalisering.

    Klinisk IT-governance: Principer och språkbruk för klinisk verksamhet och informationssystem i samklang2016Report (Other academic)
    Abstract [sv]

    Vården befinner sig i en dynamisk transformeringsfas där ökad patientinvolvering, värdebaserad vård och personaliserad vård snabbt växer i betydelse. Detta kräver en förbättrad informationsbehandling i klinisk verksamhet, kvalitetsarbete, management samt för innovation och klinisk forskning. Rapporten visar att samma information idag hanteras i flera separata strukturer, vilket i framtiden skall kunna undvikas om vi, genom god organisering, kan skapa ändamålsenliga informationssystem för klinisk verksamhet.

    Vi delar problembilden med utredningen ”Nästa fas i e-hälsoarbetet”, men medan den utredningen fokuserar på statens roll som samordnare och normerare, fokusera vi på vårdgivarnas roll och vad dessa kan göra för att förbättra strukturer och processer mellan klinisk verksamhet och IT-verksamhet.

    Rapporten genomsyras av perspektivet informatik (informationssystem). Detta område har fått ökad uppmärksamhet i och med behovet av ökad semantisk interoperabilitet, då patienter vårdas i kedjor och nätverk av många vårdgivare, och det förväntas att informationen följer patienten. Den här rapporten handlar dock inte om semantisk interoperabilitet eller teknik/arkitektur, utan om hur vårdgivarna kan och bör organisera fram adekvata informationssystem. Samtidigt som man säkrar stabilitet i de cirka 12 500 informationssystem som används i Sverige i vården idag. Vi etiketterar detta klinisk IT-governance, för att betona det kritiska i behovet av samverkan mellan klinisk verksamhet och IT-verksamhet, för att dessa mål ska uppnås. I rapporten påvisas en komplexitet som kan förefalla avskräckande, men som vi menar är en realitet som måste hanteras. Det finns tyvärr inga Silver Bullets för att lösa behovet av informationsförsörjning. Det handlar om enträgenhet, systematiskt och hårt arbete.    

    Rapporten bygger på tre studier där vi har undersökt; IT-governance hos vårdgivare i hela landet (L-ITG), hur det informatiska gapet kan överbryggas vid utveckling av kliniska beslutsstöd (BIG), samt behov av strukturer och arbetssätt för digital innovation i Innovationslabbet för eHälsa (Innovationslabbet) vid Karolinska Universitetssjukhuset. Vi som har skrivit rapporten har alla mångårig erfarenhet som forskare, praktiker och lärare inom medicin och/eller informatik.

    Klinisk digital innovation: Principer och språkbruk för klinisk digitaliseringsförmåga2016Report (Other academic)
    Abstract [sv]

    Digitalisering och innovation är två metoder som ofta nämns i samband med utveckling av vården. Utmaningen är grannlaga inte minst eftersom det handlar om att styra mot ett rörligt mål som definieras av ett samhälle i förändring, men vården har också ett ständigt tillflöde av kunskap genom forskning och kvalitetsarbete. Även den explosionsartade användningen av teknik i samhället sätter förväntansnivåer hos såväl medborgare, patienter som vårdpersonal och forskare. I den här rapporten undersöker vi hur informatisk innovation (benämnd digitalisering) kan användas som instrument i vårdens förändringsarbete. Rapporten bygger på en studie av Innovationslabbet för eHälsa, som via en initial finansiering från Vinnova, etablerades på Karolinska Universitetssjukhuset 2013–2016. Arbetet i innovationslabbet har varit explorativt, i linje med beviljad ansökan, och genom följeforskning har vi studerat innovationsverksamheten genom 25 innovationsberättelser som författas av innovationslabbets medarbetare. Frågeställningarna har handlat förmågor i en digital plattform såväl som organisatorisk innovationsförmåga i form av strukturer, metoder och relationella mekanismer. Arbetet har genomsyrats av praktikforskning och varit indelat i tre faser: I. prövning och generering av frågeställningar II. Utforskande i teori och praktik III. Analys och rapportering. Vi betraktar denna rapport som en delrapportering av en pågående kunskapsutveckling om innovation inom vård och omsorg. Resultatet från studien visar att digital plattformsförmåga och organisatorisk innovationsförmåga måste integreras för att uppnå klinisk digitaliseringsförmåga. Om detta skall vara möjligt måste det förhärskande produktperspektivet överges till förmån från ett mer verksamhetsorienterat perspektiv, där vårdgivare har möjlighet att utveckla verksamheten baserat på behov hos patienter och vårdpersonal snarare än att fokusera på implementation av nya tekniska produkter. Våra studier och erfarenheter visar att, visst behövs nya digitala plattformar för att möta framtidens utmaningar, men det är minst lika viktigt att skapa en organisatorisk innovationsförmåga som kan hantera förändring i klinisk verksamhet när nya digitala verktyg ska utvecklas och implementeras. Utforskandet av en digital plattformsförmåga som kan stödja detta dynamiska arbetssätt visar att en plattform bör ha förmåga till processorkestrering, semantikkonvertering, MT/IT-integration samt förmågan att suga ut data från olika källsystem i syfte att skapa kliniska beslutsstöd. När det gäller strukturer för innovation argumenterar vi för innovationsarenor där legitimitet är ett centralt begrepp. Om innovation ska användas som metod i vårdens förändringsarbete, måste innovation göras legitimt. Vårt förslag att göra övergången från innovationsarenor till förvaltningsstyrning är att tillämpa genererade principer för innovationsförvaltning. Gemensamt för både innovationsarenor och innovationsförvaltning är en professionsstyrning där aktiva kliniker och systemutvecklare interagerar, i syfte att nyskapa. Vi vill även lyfta fram Triple Helix som samarbetsform, men betona vikten av ett gemensamt mål för att undvika konflikter i mål och värden.

    När det gäller innovationsmetoder vill vi särskilt lyfta fram alternativa metoder som innovationsupphandling, proof of concepts, nätverkande, matchning och crowdsourcing. Digitala innovationer är flerdimensionella och ett kunskapsbidrag från studien är metoden för innovationsrymd, som på ett enkelt, men ändå kraftfullt sätt kan ”spänna upp” det flerdimensionella i digitala innovationer med fokus på värde. Vi lyfter också fram de relationella mekanismer vi sett är nödvändiga för att skapa innovation. Det är lätt att tekniken hamnar i fokus i digitaliseringssammanhang, men vi vill betona att det faktiskt är människor som agerar på innovationsarenor. Med en ömsesidig respekt för profession och uppdrag, inte minst genom att fokusera ett gemensamt mål, visar vår studie att det är möjligt att bedriva innovation i gränslandet vårdteknik, befintligt-nytt och kund-leverantör.

    Representing descriptors derived from multiple conformations as uncertain features for machine learning2013In: Journal of Molecular Modeling, ISSN 1610-2940, E-ISSN 0948-5023, Vol. 19, no 6, p. 2679-2685Article in journal (Refereed)
    Abstract [en]

    Uncertainty was introduced into the chemical descriptors of 11 datasets by conformational analysis in order to incorporate three-dimensional information and to investigate the resulting predictive performance of a state-of-the-art machine learning method, random forests, for binary classification tasks. A number of strategies for handling uncertainty in random forests were evaluated. The study showed that when incorporating three-dimensional information as uncertainty into chemical descriptors, the use of uniform probability distributions over the range of possible values, in conjunction with fractional distribution of compounds clearly outperforms the use of normal distributions as well as sampling from both normal and uniform distributions. The main conclusion of this study is that, even when distributions of uncertain values are provided, the random forest method can generate models that are almost as accurate from the expected values of these distributions alone. Hence, there seems to be little advantage to using the more elaborate methods of incorporating uncertainty in chemical descriptors when using random forests rather than replacing the distributions with single-point values. The results also show that random forest models with similar performances can also be generated using three-dimensional descriptor information derived from single (lowest-energy or Corina-derived) conformations.

    Understanding the order of agile practice introduction: Comparing agile maturity models and practitioners’ experience2019Conference paper (Refereed)
    Abstract [en]

    Agile software development has become increasingly popular over the past years. Agile methods are perceived to address challenges caused by the rapid change in the market while reducing time to market and development. As the popularity of Agile method is growing, the need for Agile adoption guidance also increases. Over the past years, Agile Maturity Models (AMMs) have been proposed to offer guidelines in Agile adoption. Agile maturity models (AMMs) suggest that Agile practices are introduced in a specific order. However, a number of evaluations of AMMs show that they are not properly validated and not suited for use in industry. Current evaluations of AMMs are based on certain criteria and not based on empirical studies. There are no studies that evaluate AMMs' suggestion to introduce Agile in certain order against industry practice. The relevance of the AMMs in the industry is not yet examined.

    In this study, we conducted a literature review to identify the order of Agile practice introduction mentioned in AMMs. We then compared the AMMs' suggestions to the strategies used by practitioners, which we elicited from a survey and a series of interviews.

    The literature survey revealed 12 AMMs which provide explicit mappings of Agile practices to maturity levels. These mappings show that the AMMs are not in agreement pertaining to the which practice is to be included in which maturity levels. The AMMs do not provide clear information nor rationale why certain practices need to be introduced in a specific maturity level. Comparison of the AMMs suggestions and the empirical study revealed that the guidance suggested by AMMs are not aligned with industry practice. The AMMs take a simplistic view of introducing Agile practices in a pre-determined order without consideration of the different contexts in industry. Our study indicates that practitioners iteratively add, remove, and modify the set of Agile practices they use to match their needs and contexts. In addition, the AMMs do not consider the potential perceived trade-off of adding Agile practices, such as team member discomfort, conflicts with other teams, and recurring bugs.

    Currently, AMMs do not provide sufficient information to guide Agile adoption in the industry. Associating Agile maturity with sets of Agile practices is inadequate and too simplified. Our results suggest that there might be no universal strategy for Agile adoption that works better than others.

    Kvaliltet i systemutveckling2006Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Systemutveckling idag strävar efter kvalitet, men man kan se flera tecken på en kvalitetsbrist i utvecklingen av system. Många projekt kommer till korta. Trots att enorma summor pengar läggs ner på IT-projekt varje år misslyckas en stor del av dem. Denna rapport behandlar frågeställningen: Hur uppnås kvalitet vid systemutveckling? Rapporten besvarar frågeställningen genom intervjuer med erfarna yrkesmän inom området. Det är deras perspektiv på kvalitet som besvarar frågeställningen.

    Resultatet visar att synen på kvalitet stämmer väl överens med vad befintliga teorier säger att kvalitet handlar om, någon form av kundtillfredsställelse. Resultatet av intervjuerna har vidare analyserats tillsammans med befintliga teorier på området. Rapporten visar på att vissa faktorer påverkar kvaliteten och uppfyllandet av den. Två av dessa faktorer är kommunikation och kultur.

    Features inom webbanalysverktyg: Vilka är viktigast för användare och varför?2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Genom att analysera olika individers surfbeteende så kan man även optimera hemsidor efter sitt eget tycke. Detta gör man med hjälp av webbanalysverktyg som finns av alla dess slag. Betalversioner såväl som gratisversioner. Dessa i sin tur innehåller olika features som möjliggör, för dig som användare, olika tillvägagångssätt och metoder över hur du ska analysera en besökares beteende. Med denna uppsats har vi valt att undersöka vilka av de vanligaste features som finns som är de viktigaste ur en användares perspektiv. För att få svar på vår huvudfrågeställning, Vilka är de viktigaste features inom webbanalysverktyg för användare och varför? gjorde vi en kvantitativ enkätundersökning innehållandes kvalitativa element. De respondenter vi hade utgjorde dock en mindre grupp som inte kunde representera en större population, men detta kan ändå ligga till grund för vidare forskning med tanke på att våra kvalitativa element gav bra riktmärken. Under analysen framgick det att flera features var mer prioriterade än andra utifrån en användares perspektiv och vi identifierade ett flertal faktorer som stöttade detta.

     

    Studien resulterade i en beskrivning över vilka som är de mest förekommande features, hur viktiga de är för användare samt vilka faktorer som antyder på detta.

    The influence of inputs in the information security policy development: an institutional perspective2022In: Transforming Government: People, Process and Policy, ISSN 1750-6166, E-ISSN 1750-6174, Vol. 16, no 4, p. 418-435Article in journal (Refereed)
    Abstract [en]

    Purpose: The purpose of this paper is to investigate what role literature-based inputs have on the information security policy (ISP) development in practice.

    Design/methodology/approach: A literature review is carried out to identify commonly used inputs for ISP development in theory firstly. Secondly, through the lens of institutional theory, an interpretive approach is adapted to study the influence of literature-based inputs in the ISP development in practice. Semi-structured interviews with senior experienced information security officers and managers from the public sector in Sweden are carried out for this research.

    Findings: According to the literature review, 10 inputs for ISP development have been identified. The results from the interviews indicate that the role inputs have on the ISP development serves as more than a rational tool, where organisational context, institutional pressures and the search for legitimacy play an important role.

    Research limitations/implications: From the institutional perspective, this study signifies the influence of inputs on ISP development can be derived from institutionalised rules or practices established by higher authorities; actions and practices that are perceived as successful and often used by other organisations; the beliefs of what is viewed as appropriate to meet the specific pressures from stakeholders.

    Practical implications: This research recommends five practical implications for practitioners working with the ISP development. These recommendations aim to create an understanding of how an ISP could be developed, considering more than the rational functionalist perspective.

    Originality/value: To the best of the authors' knowledge, it is the first of its kind in examining the role of literature-based inputs in ISP development in practice through the lens of institutional theory.

    The state-of-practice in requirements elicitation: an extended interview study at 12 companies2021In: Requirements Engineering, ISSN 0947-3602, E-ISSN 1432-010X, Vol. 26, no 2, p. 273-299Article in journal (Refereed)
    Abstract [en]

    Requirements engineering remains a discipline that is faced with a large number of challenges, including the implementation of a requirements elicitation process in industry. Although several proposals have been suggested by researchers and academics, little is known of the practices that are actually followed in industry. Our objective is to investigate the state-of-practice with respect to requirements elicitation, by closely examining practitioners' current practices. To this aim, we focus on the techniques that are used in industry, the roles that requirements elicitation involves, and the challenges that the requirements elicitation process is faced with. As method, we conducted an interview-based survey study involving 24 practitioners from 12 different Swedish IT companies, and we recorded the interviews and analyzed these recordings by using quantitative and qualitative methods. Several results emerged from the studies. Group interaction techniques, including meetings and workshops, are the most popular type of elicitation techniques that are employed by the practitioners, except in the case of small projects. Additionally, practitioners tend to use a variety of elicitation techniques in each project. We noted that customers are frequently involved in the elicitation process, except in the case of market-driven organizations. Technical staff (for example, developers and architects) are more frequently involved in the elicitation process compared to the involvement of business or strategic staff. Finally, we identified a number of challenges with respect to stakeholders. These challenges include difficulties in understanding and prioritizing their needs. Further, it was noted that requirements instability (i.e., caused by changing needs or priorities) was a predominant challenge. These observations need to be interpreted in the context of the study. We conclude that the relevant observations regarding the survey participants' experiences should be of interest to the industry; experiences that should be analyzed in the practitioners' context. Researchers may find evidence for the use of academic results in practice, thereby inspiring future theoretical work, as well as further empirical studies in the same area.

    Studies in Semantic Modeling of Real-World Objects using Perceptual Anchoring2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Autonomous agents, situated in real-world scenarios, need to maintain consonance between the perceived world (through sensory capabilities) and their internal representation of the world in the form of symbolic knowledge. An approach for modeling such representations of objects is through the concept of perceptual anchoring, which, by definition, handles the problem of creating and maintaining, in time and space, the correspondence between symbols and sensor data that refer to the same physical object in the external world.

    The work presented in this thesis leverages notations found within perceptual anchoring to address the problem of real-world semantic world modeling, emphasizing, in particular, sensor-driven bottom-up acquisition of perceptual data. The proposed method for handling the attribute values that constitute the perceptual signature of an object is to first integrate and explore available resources of information, such as a Convolutional Neural Network (CNN) to classify objects on the perceptual level. In addition, a novel anchoring matching function is proposed. This function introduces both the theoretical procedure for comparing attribute values, as well as establishes the use of a learned model that approximates the anchoring matching problem. To verify the proposed method, an evaluation using human judgment to collect annotated ground truth data of real-world objects is further presented. The collected data is subsequently used to train and validate different classification algorithms, in order to learn how to correctly anchor objects, and thereby learn to invoke correct anchoring functionality.

    There are, however, situations that are difficult to handle purely from the perspective of perceptual anchoring, e.g., situations where an object is moved during occlusion. In the absence of perceptual observations, it is necessary to couple the anchoring procedure with probabilistic object tracking to speculate about occluded objects, and hence, maintain a consistent world model. Motivated by the limitation in the original anchoring definition, which prohibited the modeling of the history of an object, an extension to the anchoring definition is also presented. This extension permits the historical trace of an anchored object to be maintained and used for the purpose of learning additional properties of an object, e.g., learning of the action applied to an object.

    Abstract [en]

    In this paper, we examine how to ground symbols referring to objects in perceptual data from a robot system by examining object entities and their changes over time. In particular, we approach the challenge by 1) tracking and maintaining object entities over time; and 2) utilizing an artificial neural network to learn the coupling between words referring to actions and movement patterns of tracked object entities. For this purpose, we propose a framework which relies on the notations presented in perceptual anchoring. We further present a practical extension of the notation such that our framework can track and maintain the history of detected object entities. Our approach is evaluated using everyday objects typically found in a home environment. Our object classification module has the possibility to detect and classify over several hundred object categories. We demonstrate how the framework creates and maintains, both in space and time, representations of objects such as 'spoon' and 'coffee mug'. These representations are later used for training of different sequential learning algorithms in order to learn movement actions such as 'pour' and 'stir'. We finally exemplify how learned movements actions, combined with common-sense knowledge, further can be used to improve the anchoring process per se.

    Abstract [en]

    The introduction of computationally efficient binary feature descriptors has raised new opportunities for real-world robot vision applications. However, brute force feature matching of binary descriptors is only practical for smaller datasets. In the literature, there has therefore been an increasing interest in representing and matching binary descriptors more efficiently. In this article, we follow this trend and present a method for efficiently and dynamically quantizing binary descriptors through a summarized frequency count into compact representations (called fsum) for improved feature matching of binary pointfeatures. With the motivation that real-world robot applications must adapt to a changing environment, we further present an overview of the field of algorithms, which concerns the efficient matching of binary descriptors and which are able to incorporate changes over time, such as clustered search trees and bag-of-features improved by vocabulary adaptation. The focus for this article is on evaluation, particularly large scale evaluation, compared to alternatives that exist within the field. Throughout this evaluation it is shown that the fsum approach is both efficient in terms of computational cost and memory requirements, while retaining adequate retrieval accuracy. It is further shown that the presented algorithm is equally suited to binary descriptors of arbitrary type and that the algorithm is therefore a valid option for several types of vision applications.

    Abstract [en]

    To provide a spoken interaction between robots and human users, an internal representation of the robots sensory information must be available at a semantic level and accessible to a dialogue system in order to be used in a human-like and intuitive manner. In this paper, we integrate the fields of perceptual anchoring (which creates and maintains the symbol-percept correspondence of objects) in robotics with multimodal dialogues in order to achieve a fluent interaction between humans and robots when talking about objects. These everyday objects are located in a so-called symbiotic system where humans, robots, and sensors are co-operating in a home environment. To orchestrate the dialogue system, the IrisTK dialogue platform is used. The IrisTK system is based on modelling the interaction of events, between different modules, e.g. speech recognizer, face tracker, etc. This system is running on a mobile robot device, which is part of a distributed sensor network. A perceptual anchoring framework, recognizes objects placed in the home and maintains a consistent identity of the objects consisting of their symbolic and perceptual data. Particular effort is placed on creating flexible dialogues where requests to objects can be made in a variety of ways. Experimental validation consists of evaluating the system when many objects are possible candidates for satisfying these requests.

    IT-stöd inom kommunal äldrevård och omsorg: – till vad, för vem, av vilka?2006Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Arbetet inom äldrevård och omsorg måste effektiviseras för att möta morgondagens behov. Det framtida rekryteringsproblemet behöver också lösas och vårdyrket måste bli mer attraktivt, t ex genom att följa med i den tekniska utvecklingen.

    En e-postbaserad enkät skickades ut till 13 svenska kommuner för att kunna sammanställa en aktuell lägesrapport över vilka IT-stöd som idag förekommer inom kommunal äldrevård och omsorg, samt till vad stödet används, vem det är till för och vilka det är som använder IT-stödet.

    Stationär dator, mobiltelefon och digitalkamera är de IT-stöd som flest respondenter svarade används i verksamheten.

    Stationär dator används främst för att hämta och registrera vårdtagardokumentation, men även för att skicka e-post och för ekonomiadministration. Det finns dock ingen specifik som stödet kan sägas vara till för. IT-stödet används framför allt av enhetschefer, vårdpersonal och administrativ personal.

    Mobiltelefon används givetvis främst för att ringa och skicka SMS, men även för att ta emot larm från vårdtagare samt tillkalla hjälp. Inte heller för detta IT-stöd finns det någon specifik som stödet kan sägas vara till för. Stödet används främst av övrig vårdpersonal, vårdpersonal och enhetschefer.

    Digitalkamera används främst för att förstärka dokumentation genom att dokumentera vårdtagares sår och läkningsprocess. Stödet är i första hand till för vårdtagare och läkare för att dessa utförarkategorier bl a undviker läkarbesök som inte är nödvändiga, men även vårdpersonal då dessa kan använda digitalkamera vid rådgivning. IT-stödet används främst av vårdpersonal.

    Virtual knowledge sharing in Chinese context: Review of influencing factors2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study is to look for influencing factors on virtual knowledge sharing in Chinese context. To achieve this, a literature review was conducted using the systematic approach described by Webster & Watson (2002). There has been made quite a lot of research about knowledge sharing and virtual communities in Chinese context, but I have not found any literature review that synthesizes it.

    14 factors, modeled as concepts, were found in 35 articles, and then synthesized like a concept model. The factors are: face; collectivism; guanxi; in-group/out-group distinction; modesty; hierarchy; competitiveness; informal communication; instant messaging; Confucian dynamism; incentives; language; time spent/time saved, and trust.

    Research gaps, trends, and implications for developers and managers are discussed.

    The value of this literature review is that it will make it easier for future scholars and researchers that are doing research in knowledge sharing. This paper also provides useful knowledge for developers and managers of knowledge sharing systems in Chinese contexts.

    Dataspelsberoende: - Och spelkomponenter i World of Warcraft2007Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Diskussionen i Sverige angående dataspelsberoende och att främst att ungdomar, spenderar

    mycket av sin vakna tid framför spelen, har på senare tid tagit fart i media. Många har

    diskuterat om inte detta är ett samhällsproblem. WoW (World of Warcraft) är ett av de

    populäraste spelen i världen och lockar väldigt många individer.

    Syftet med denna uppsats har varit att undersöka spelet WoW för att ta reda på vilken eller

    vilka av dess spelkomponenter som kan ha ett samband med ett beroende. Detta har gjorts

    genom experiment, observation och intervju av individer som spelar spelet.

    Syftet anses uppnått och frågeställningen i arbetet har besvarats. De komponenter som ansågs

    ha ett samband med beroende var Spelare (spelarna i spelet påverkade varandra på en social

    nivå) och Karaktärsuppgraderingen (jakten efter att få sin karaktär att bli bättre och bättre).

    Aren't the fundamental concepts of work systems about actions?2005In: Promote IT 2005: Proceedings of the Fifth Conference for the Promotion of Research in IT at New Universities and University Colleges in Sweden, Lund: Studentlitteratur , 2005, p. 357-366Conference paper (Refereed)
    Abstract [en]

    The scope of this paper is to „infuse‟ the so called work sys-tem approach (WSA) with a suggested theoretical basis. WSA is a ge-neric approach for understanding information systems in organizations with its aim set on high relevance. By relating the, so called, work practice approach the endeavor of the paper is to elaborate on actions as a theoretical and more rigorous basis for WSA. The results from this elaboration are then used to dispute some lines of criticism that has been raised against WSA. The study can be characterized as ex-plorative and the results points out a direction that states that further cross fertilization between the two approaches would be fruitful.

    Work system principles: towards a justified design theory on the grounds of socio-instrumental pragmatism2008In: Proceedings of the 3rd international conference on the pragmatic web: innovating the interactive society, ICPW '08 / [ed] Pär J. Ågerfalk, Harry Delugach, Mikael Lind, New York, NY: ACM , 2008, p. 69-76Conference paper (Refereed)
    Abstract [en]

    The aim of the paper is to explore a possible theoretical foundation for the `work system approach'. The concept of work systems has been suggested as the core object of study in the field of information systems. The scope of the work system approach is determined by pragmatic relevance and high comprehensibility, with the goal of being applicable for professionals in both IT and business as well as IS researchers. This approach has, however, been criticized for having theoretical shortcomings. In this paper, a theoretical foundation is suggested and explored by relating it to work practice theory and its roots in socio-instrumental pragmatism. The results show that it is both possible and fruitful to ground the work system approach theoretically in socio-instrumental actions.

    Metabolomics Analytics Workflow for Epidemiological Research: Perspectives from the Consortium of Metabolomics Studies (COMETS)2019In: Metabolites, ISSN 2218-1989, E-ISSN 2218-1989, Vol. 9, no 7, article id E145Article in journal (Refereed)
    Abstract [en]

    The application of metabolomics technology to epidemiological studies is emerging as a new approach to elucidate disease etiology and for biomarker discovery. However, analysis of metabolomics data is complex and there is an urgent need for the standardization of analysis workflow and reporting of study findings. To inform the development of such guidelines, we conducted a survey of 47 cohort representatives from the Consortium of Metabolomics Studies (COMETS) to gain insights into the current strategies and procedures used for analyzing metabolomics data in epidemiological studies worldwide. The results indicated a variety of applied analytical strategies, from biospecimen and data pre-processing and quality control to statistical analysis and reporting of study findings. These strategies included methods commonly used within the metabolomics community and applied in epidemiological research, as well as novel approaches to pre-processing pipelines and data analysis. To help with these discrepancies, we propose use of open-source initiatives such as the online web-based tool COMETS Analytics, which includes helpful tools to guide analytical workflow and the standardized reporting of findings from metabolomics analyses within epidemiological studies. Ultimately, this will improve the quality of statistical analyses, research findings, and study reproducibility.

    Relationship strength and network form: An agent-based simulation of interaction in a business network2014In: Australasian Marketing Journal, ISSN 1441-3582, E-ISSN 1839-3349, Vol. 22, no 1, p. 15-27Article in journal (Refereed)
    Abstract [en]

    Given an international business network with the same focal resource, the same source and markets, but exhibiting two different inter-related sub-networks with different internal organization, we study how these network forms affects interactions. The purpose is to compare and explain differences between the two network forms and the effects this have on dyadic international relationship development using a qualitative experimental methodology involving computerized simulations. We simulate various changes in quality variation of the focal resource as well as changing demand preferences of buyers to investigate the impact on relationship strength. From this we develop three scenarios.

    Planar segmentation for Geometric Reverse Engineering using data from a laser profile scanner mounted on an industrial robot2008Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Laser scanners in combination with devices for accurate orientation like Coordinate Measuring Machines (CMM) are often used in Geometric Reverse Engineering (GRE) to measure point data. The industrial robot as a device for orientation has relatively low accuracy but the advantage of being numerically controlled, fast, flexible, rather cheap and compatible with industrial environments. It is therefore of interest to investigate if it can be used in this application.

    This thesis will describe a measuring system consisting of a laser profile scanner mounted on an industrial robot with a turntable. It will also give an introduction to Geometric Reverse Engineering (GRE) and describe an automatic GRE process using this measuring system. The thesis also presents a detailed accuracy analysis supported by experiments that show how 2D profile data can be used to achieve a higher accuracy than the basic accuracy of the robot. The core topic of the thesis is the investigation of a new technique for planar segmentation. The new method is implemented in the GRE system and compared with an implementation of a more traditional method.

    Results from practical experiments show that the new method is much faster while equally accurate or better.

    Abstract [en]

    High accuracy 3D laser measurment systems are used in applications like inspection and reverse engineering (RE). With automatic RE in mind, we have designed and built a system that is based on a laser profile scanner mounted on a standard industrial robot with a turntable. This paper is concerned with the relatively complex accuracy issues of such a system. The different parts of the system are analyzed individually and a brief discussion of how they interact is given. Finally a detailed analysis of the scanner head along with experimental results is presented.

    Designa webbplatser med hjälp av haloeffekten: en studie som behandlar visuella intryck av webbplatser samt tar fram kriterier för att mäta dessa intryck2007Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Kan man kombinera två så vitt skilda synsätt som användbarhet och grafisk form på samma webbplats? Jag undersöker möjligheten att göra detta genom att ge användaren ett positivt visuellt första intryck för att sedan låta resten av webbplatsen präglas av användbarhet. Att det första intrycket färgar övriga intryck är ett fenomen som kallas haloeffekten (Hinton, 1993). Hur skapar man då ett positivt första intryck? Jag har utgått från en definition av estetik där begreppet är uppdelat i två dimensioner, klassisk och uttryckande (Lavie och Tractinsky, 2003). Den klassiska dimensionen har mycket gemensamt med användbarhetsdesign medan den uttryckande estetiken inte har det. Den bygger istället på designerns kreativitet och förmåga att bryta mot designkonventioner (ibid.). Det är genom att utnyttja denna dimension jag vill kunna skapa det positiva första intrycket. Jag designar två webbplatser där den ena har en uttryckande estetisk förstasida men där de övriga delarna av webbplatsen är klassiskt estetiska. Den andra webbplatsen är helt designad med klassisk estetik och det enda som skiljer dem åt är alltså förstasidan. Med hjälp av dessa webbplatser genomför jag en pilotundersökning med syftet att undersöka om det finns samband mellan första intrycket och helhetsintrycket. Undersökningen jag genomför är dock alltför liten för att resultatet ska kunna generaliseras.

    För att kunna genomföra undersökningen behövde jag ett sätt att mäta visuella intryck. Jag utformar även kriterier för att designa webbplatser samt för att mäta dessa visuella intryck. Kriterierna är framtagna genom litteraturstudier och jag testar dem med hjälp av pilotundersökningen. Jag presenterar i mina slutsatser en lista med 14 kriterier som kan användas för att mäta visuella intryck av webbplatser. Dessa kriterier kan även användas för att designa webbplatser.
