    Thesis Proposal: A Method for Information Classification2017Report (Other academic)
    Abstract [en]

    In the highly digitalized world in which we live today, information and information systems have become key assets to organizations.  These assets need to be managed properly because it is difficult to safeguard assets that an organization does not know exist and does not know the value they offer. In an Information Security Management System (ISMS), asset management is an important activity as it aims at identifying, assigning ownership and adding protection to information assets. Within asset management, one activity is information classification that has the objective to ensure that information receives an appropriate level of protection in accordance with its importance to the organization. In practice, this is usually done using a classification scheme, and the result is handled as input to the risk analysis. Information classification is a well-known practice for all kind of organizations, both in the private and public sector, and is included in different variants in standards such as ISO/IEC 27002, COBIT and NIST-SP800.

    However, information classification has received little attention from academia, and many organizations are struggling with the implementation. Little is known about the reasons behind why it is problematic, and how to address such issues. Furthermore, the existing methods, described in, e.g., standards do not provide a coherent and systematic approach to information classification. The short descriptions in standards, and literature alike, leave out important aspects needed for many to adopt any kind of information classification. For instance, there is a lack of detailed descriptions regarding (1) overview of procedures, and concepts, (2) which roles are involved in the classification, and how they interact, (3) how to tailor the method for different situations and (4) a framework that structures and guides the classification. If information classification is not implemented in an organization, the organization might not know what information they possess, what the value of the information is, but even if it is implemented, an unclear approach can lead to information being under or overvalued, which, in turn, lead to under or overprotected information.

    This thesis aims to increase the applicability of information classification by devising a method for information classification in ISMS that draws from established standards and practice. In order to address this aim, a Design Science Research (DSR) study has been performed in five cycles. The contributions so far include an identification of issues and enablers for information classification and propose a component-based method for information classification. Furthermore, eighth design principles underpinning an information classification method are presented. Additionally, an outline for further research is provided, where the objectives are to further develop the method by addressing the context around information classification (the risk analysis and security controls), and by adding usage views to the method. Finally, a security declaration as an addition to the information classification method is outlined as a complement for tying security controls to the information classification scheme.

    Certifications in Higher Education - Friend or Foe?2014Conference paper (Refereed)
    Abstract [en]

    The aim of this study is to investigate the uncritical approach among teachers and students of how certifications are used and applied within higher education. This paper offers a clearer image of how to use certification in a learning environment that support student learning and further developing the academia as a learning organisation.  In the last decade universities worldwide has started to adopt certifications offered by multinational corporations, such as Cisco and Microsoft. For example, Cisco’s curriculum is taught in over 10.000 academies such as universities to more than 1.000.000 students currently, which reveals the huge influences those certifications have for the organisation of courses and examination of academic skills.  Academy and industry needs to collaborate to offer students relevant tools and knowledge, but the lack of uncritical views based on scientific values and proven experience challenges teachers to explicit what knowledge have to be taught within academia to reach further academic goals.  The methods used are initially a literature study to identify positive aspects and challenges with integrated certifications. Based on these results, we have performed interviews with students, teachers and certified instructors with different backgrounds.  Literature describing information and communications technology (ICT) certifications mainly refer to positive aspects such as meeting job market needs, standardisation of courses, and decreased time for course development. Challenges identified raise several questions and call for further investigation. Among challenges identified were companies practically deciding examination criteria, student’s recall learnt material rather than understanding concepts, and the usage of non-academic material.  Interviews reveal that students are aware of many challenges, but still the benefits of achieving a certification outweighs. For instance, students rather accept a course with out-dated material and company decided examination criteria that result in a certification than taking a course based on research and examinations that foster creativity through reflection, analysing skills with no certification.  From a teacher and instructor perspective, the interviews reveal that there is awareness about the challenges of using certifications in higher education. One of the pedagogical issues we would like to present is how to create a learning environment with embedded certification in a course rather than basing courses on certifications alone.  This paper also open up for a discussion on how these results affect other areas than the ICT domain, but also on how the challenges can be tackled from a higher education perspective that rethink the academia as a learning organisation.

    Erfarenheter, lärdomar och effekter med gränsöverskridande arbete för utbytesstudier2018In: NU2018 - Det akademiska lärarskapet, 2018, article id 685Conference paper (Refereed)
    Abstract [sv]

    I Högskolan i Skövdes (HS) nuvarande utvecklingsplan beskrivs att samtliga utbildningsprogram som ges vid lärosätet skall erbjuda möjligheter till studier utomlands. Som en konsekvens har en strategisk satsning för att stimulera en ökad mobilitet vid HS initierats genom att Institutionen för informationsteknologi (IIT) tillsammans med verksamhetsstödet har deltagit i ett UHR-projekt med fokus på vägledningsprocessen i samband med mobilitet.

    Projektet har pågått under 18 månader och ett 10-tal deltagare som representerar de flesta roller som är involverade i internationaliseringsarbetet på IIT och verksamhetsstödet har ingått. Projektet har bedrivits främst som en serie av workshoppar där parallell datainsamling har skett med hjälp av intervjuer och enkätstudier.

    I detta bidrag vill vi visa några av de mål som projektet fokuserat på samt syftet med dessa. Projektet har haft följande mål:

    Identifiera minst tre partnerlärosäten som passar varje utbildningsprogram - Målet syftar till att kartlägga både existerande och nya partnerlärosäte för att på så sätt sänka tröskeln för studenter som är intresserade av utbyte, men som har svårt att hitta lämpliga alternativ.

    Tydliggöra roll- och ansvarsfördelning i mobilitetsprocessen - Detta mål syftar till att utforma processbeskrivningar för att tydliggöra roll- och ansvarsfördelning kring utresandeprocessen för programansvarig, ämnesföreträdare, internationell koordinator, studie- och karriärvägledaren, studenten och partnerlärosätet. Även kommunikationsaspekter och studentperspektiv beaktas i detta mål.

    Skapa adekvat vägledning och informationsinsatser gentemot studenterna - Syftet med målet är att utveckla, strukturera och systematisera informationsvägar och kommunikation mellan vägledning, programansvarig, partnerlärosäte och studenter.

    Identifiera och utvärdera nyckelfaktorerna för att förbättra stödet till studenterna, undanröja hinder i mobilitetsprocessen samt underlätta programansvarigas och studie- och karriärvägledarnas arbete med utresande studenter - Målet är att identifiera och utvärdera nyckelfaktorer som hindrar mobilitet som kan spridas internt på HS samt externt för att i förlängningen öka mobiliteten bland Sveriges studenter.

    Se till att samtliga kandidatprogram på IIT har en termin avsatt för utlandsstudier och undanröja de hinder som finns i befintliga programstrukturer - Syftet är att göra det enklare för studenter att under sin ordinarie studietid genomföra utbytesstudier utan att deras studier vid HS blir drabbade av förkunskapsstrukturer som hindrar fortsatta studier vid hemkomst.

    I studien inkludera de studenter som har varit intresserade eller sökt utbytesstudier men som inte kommit iväg på utbyte - Syftet är att skapa en god översikt över vilka skäl denna studentkategori har haft för att avstå utbytesstudier för att på så vis kunna förbättra existerande processer för utbytesstudier och därmed minimera risken att intresserade studenter väljer att avstå från utbytesstudier.

    Vid projektets avslut analyserades projektets direkta och indirekta interorganisatoriska effekter tillsammans med aktuell statistik för de studenter som under 2017 nominerats för utbytesstudier. En uppenbar effekt av projektets arbete är att antalet studenter som 2017 vid IIT nominerats för utbytesstudier ökat kraftigt. Likaså observeras ökade kunskaper om processen kring utbytesstudier och ett förbättrat studentperspektiv och bättre kunskaper om studenternas upplevelse av nomineringsprocessen.

    Under presentation vill vi visa upp fler detaljer från vår analys samt hur vi planerar att arbeta vidare med de resultat vi fått fram i projektet.

    Revisiting information security risk management challenges: a practice perspective2019In: Information and Computer Security, E-ISSN 2056-4961, Vol. 27, no 3, p. 358-372Article in journal (Refereed)
    Abstract [en]

    Purpose: The study aims to revisit six previously defined challenges in information security risk management to provide insights into new challenges based on current practices. Design/methodology/approach: The study is based on an empirical study consisting of in-depth interviews with representatives from public sector organisations. The data were analysed by applying a practice-based view, i.e. the lens of knowing (or knowings). The results were validated by an expert panel. Findings: Managerial and organisational concerns that go beyond a technical perspective have been found, which affect the ongoing social build-up of knowledge in everyday information security work. Research limitations/implications: The study has delimitation as it consists of data from four public sector organisations, i.e. statistical analyses have not been in focus, while implying a better understanding of what and why certain actions are practised in their security work. Practical implications: The new challenges that have been identified offer a refined set of actionable advice to practitioners, which, for example, can support cost-efficient decisions and avoid unnecessary security trade-offs. Originality/value: Information security is increasingly relevant for organisations, yet little is still known about how related risks are handled in practice. Recent studies have indicated a gap between the espoused and the actual actions. Insights from actual, situated enactment of practice can advise on process adaption and suggest more fit approaches.

    Abstract [en]

    This paper presents a systematic literature review performed to investigate if there is a prevailing definition of reference implementation in the standards community, and how reference implementations are referenced to be used within the standards community. The literature review targets all electronically available core journals and conferences in the field, and the results are classified according to a framework introduced in the paper. We found that there is one definition that focuses on conformance testing, but the results from the literature review show more uses of reference implementations such as when developing standards, when implementing them, and when developing products.

    Abstract [en]

    This paper presents a comprehensive systematic literature review of information classification (IC) enablers. We propose a classification based on the well-known levels of management: strategic, tactical and operational. The results reveal that a large number of enablers could be adopted to increase the applicability of IC in organizations. The results also indicate that there is not one single enabler solving the problem, but rather several enablers can influence the adoption.

    Abstract [en]

    This paper presents an extensive systematic literature review with the aim of identifying and classifying issues in the information classification process. The classification selected uses human and organizational factors for grouping the identified issues. The results reveal that policy-related issues are most commonly described, but not necessarily the most crucial ones. Furthermore, gaps in the research field are identified in order to outline paths for further research.

    Upplevelser av att leva med lungcancer: En litteraturbaserad studie2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Lung cancer is a disease with poor prognosis, with many people that falls ill each year. It is a disease which leads to numerous and severe symptoms that create much suffering. Aim: The aim of this study was to describe patients' experiences of living with lung cancer in daily life. Methods: A literature study was conducted with a qualitative approach. Twelve scientific articles were reviewed and analyzed according to a model for a literature study. Results: Six categories were identified: live with uncertainty, stigma and guilt, experience of disease-related symptoms, a changed self-esteem, to get support and be confirmed and thrown between hope and despair. Discussion: There was a need for patients to live as independent as possible, social support and the support from health professionals was crucial for them to cope with it. Support overall was important for patients to be able to handle most situations. By acquiring knowledge about patients' with lung cancers experiences the nurse can be a better support for the patient in order to alleviate patients suffering.

    ANHÖRIGAS UPPLEVDA SITUATION NÄR EN NÄRSTÅENDE VÅRDAS PÅ EN INTENSIVVÅRDSAVDELNING: -En litteraturöversikt2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: The intensive care unit is a department where critically and acute sick patients are being treated. The department has specialized routines, equipment to treat and screening. Nurses on a intensive care unit are responsible for the treatment of patients as well as the leadership of the workforce. The nurses are also responsible to acknowledge the patient’s relatives. Therefore, it is of great importance for the nurses to understand relatives’ experiences in this situation, to be able to give treatment of good quality to relatives too. Aim: To describe the experience of relatives to patients who are being treated at the intensive care unit. Method: A literature review of scientific articles with a qualitative standpoint, aimed towards the experiences of relatives to intensive care unit patients. Results: Relatives experienced that a lot of factors affected them negatively. Routines, equipment and treatment were experienced as unfamiliar and confusing. The situation made it hard for the relatives to experience being close to the patient. Relatives experienced that good communication and information made the situation positive. Relatives experienced that being a part and having a say in the patients’ treatment were important. Conclusion: To be a relative at the intensive care unit can feel unfamiliar and differ from other kinds of departments. There are rules, equipment and situations that makes it difficult for the relatives to see the context of the situation. It is of great importance that the healthcare is attentive and give the relatives the possibility to understand the context.

    Interim Report of the ICES/HELCOM Working Group on Integrated Assessments of the Baltic Sea (WGIAB): 18-22 April 2016 Helsinki, Finland2016Report (Other academic)
    Abstract [en]

    The ICES/HELCOM Working Group on Integrated Assessments of the Baltic Sea (WGIAB) meeting was held in Helsinki (Finland), 18-22 April 2016. The meeting was attended by 26 participants from five countries and chaired by Laura Uusitalo, Fin-land, Saskia Otto, Germany, Martin Lindegren, Denmark, and Lena Bergström, Swe-den. This was the first year of the new three-year Terms of Reference (ToR) for WGIAB. The main working activities in 2016 were to A) develop the trait-based ap-proach of understanding the ecosystem function, and B) explore the social-ecological system, including indicator development, revising the conceptual model, and devel-oping case studies. As a primary outcome of the ToR A, we built on our previous work on integrated ecosystem assessments (IEAs) in the Baltic Sea, but extended it beyond considering changes in abundances of a few dominant species, to accounting for community-wide changes in a number of key traits across multiple trophic levels. These traits represent various ecosystem functions upon which we derive important ecosystem services. By investigating temporal changes in the community weighted mean traits of phyto-plankton, zooplankton, zoobenthos, and fish, we demonstrated whether trait reor-ganizations at the level of entire communities occurred in the Central Baltic Sea as a result of the 1980s regime shift. Using in total 29 traits combined for all groups we found indications of two breakpoints across all four taxonomic groups over the last decades, i.e. one around 1990 and one around 2000. Further work will focus on ex-ploring the nature of the changes in trait composition and on standardizing the num-ber of traits and data types (i.e. binary, continuous or categorical) across taxonomic group.In addition, we collected data on key functional groups and abiotic variables in all main sub-basins of the Baltic Sea, setting the stage for a cross-regional comparison of temporal patterns and trends in lower trophic level in the face of recent develop-ments in climate-related drivers.With reference to Tor B, to explore how social indicators could be used in parallel with biological indicators in an integrated assessment framework, we developed a conceptual model of interrelationships between ecosystem and society. We used the model as a basis for mapping factors to be accounted for in the ecosystem-based management using the Baltic salmon and clupeid species as case studies. The models depict 1) the structure of the foodweb relevant to the target species, 2) the key com-munity level and population traits that contribute to the state of the species, 3) main pressures affecting the foodweb and their effects on the species, 4) key management measures, and 5) benefits that the species can produce for society.To support the development of Ecosystem Overview the group members evaluated the probability of occurrence and the magnitude of the effect of 15 pressures occur-ring in the Baltic Sea. The top five pressures identified were input of nutrients, in-creased temperature, decreased salinity, input of hazardous substances, and input or spread of non-indigenous species.The work will continue intersessionally and the next meeting of WGIAB is planned to be held in Lisbon, Portugal, back-to-back with WGCOMEDA and WGEAWESS.

    Report of the ICES/HELCOM Working Group on Integrated Assessments of the Baltic Sea (WGIAB)2015Report (Other academic)
    Abstract [en]

    The ICES/HELCOM Working Group on Integrated Assessments of the Baltic Sea(WGIAB) was established in 2007 as a forum for developing and combining ecosystembasedmanagement efforts for the Baltic Sea. The group intends to serve as a scientificcounterpart and support for the ICES Baltic Fisheries Assessment Working Group(WGBFAS) as well as for efforts and projects related to Integrated Ecosystem Assessments(IEA) within ICES and HELCOM. The group works in cooperation with similargroups within the ACOM/SCICOM Steering Group on Integrated Ecosystem Assessments(SSGIEA).The 2015 WGIAB meeting was held in Cádiz, Spain, from 9–13 March, back-to-backwith the meeting of its counterpart in the Working Group on Ecosystem Assessmentof Western European Shelf Seas (WGEAWESS). The meetings had joint sessions as wellas WG specific work, and some participants effectively participated in both meetings.The WGIAB meeting was attended by 27 participants from nine countries. The meetingwas chaired by Christian Möllmann, Germany, Laura Uusitalo, Finland and Lena Bergström,Sweden.This was the last year of the ongoing three-year Terms of Reference (ToR) for WGIAB.The main working activities in 2015 were to i) conduct studies on Baltic Sea ecosystemfunctioning with the goal to publish case studies from different parts of the Baltic Seain peer-reviewed journals, ii) work on the demonstration exercise to develop ecosystem-based assessment and advice for Baltic fish stocks focusing on cod (DEMO) withmultiple approaches, iii) plan further how to integrate the social and economic aspectsmore tightly in the WGIAB work, and iv) discuss the future focus and format of theWGIAB work.The Baltic ecosystem functioning activity focused on identifying and exploring keytrends and linkages in the Baltic Sea foodweb. This was pursued by presentation andfurther discussion of ongoing intersessional work on foodweb modelling and integratedanalyses, and by exercises to develop conceptual models Baltic Sea foodwebsand the links to ecosystem function. Long-term monitoring datasets on the abiotic andbiotic parts of the Baltic Sea Proper ecosystem were updated for use in the continuedwork to develop environmental indicators for fisheries and marine management.The focus of the DEMO 3 (DEMOnstration exercise for Integrated Ecosystem Assessmentand Advice of Baltic Sea cod) was on finding a way to use the results from theDEMO1 and DEMO2 workshops in short and midterm projections/scenarios of Balticcod dynamics based on different types of modelling, as well as designing methodologyand modelling data for practical implementation of Integrated Advice for Baltic cod.The WGIAB was positively inclined towards including social and economic aspectsinto the integrated assessment. Openings to this path were provided by presentationon ongoing project work, and discussing their linkages to ecological aspects. It wasseen as crucial that experts on social and economic analysis should be included andtake an active part in the future work of the group.The group concluded that its upcoming work should focus more closely on functionaldiversity, which was identified as a recurring issue in the Baltic Sea. This approach wasalso identified as a useful connection point between scientific and management aspectsin order for the group to continue serving as a forum for developing ecosystem-basedmanagement efforts in the Baltic Sea. A focus on functional diversity was also seen as2 | ICES WGIAB REPORT 2015a potentially feasible way of bringing together management aspects for different sectors,by linking to ecosystem services concepts.The group proposed Saskia Otto, Germany and Martin Lindegren, Denmark as newincoming Chairs, together with Lena Bergström, Sweden and Laura Uusitalo, Finland.Having four Chairs is justified due to the wide scope of the group's work, as well asthe increased work load due to the planned new foci.

    Unga kvinnors användande av sexualitet som självskadebeteende: En kvalitativ studie2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Young girls that self-harm themselves have recent years been in focus. Thosewho earlier in life have been sexually abused are overrepresented among these women thatself-harm themselves through their sexuality.Aim: The aim of this study was to illustrate young women’s experiences of sexuality as aself-harm behavior.Method: A qualitative study with a phenomenological approach of own written stories.Result: Young women that harm themselves with their sexuality seek acknowledgement forinstance by publishing pictures on the internet to receive positive feedback on theirappearance. Further they use their sexuality to achieve a rush and a sense of suffice and bythat mitigate their anxiety. These women need a lot of support from their surroundings inorder to understand and process their self-harm behavior.Conclusion: School nurses need to pay attention that sexuality as a self-harm behavior existsin all social classes. The school nurse can through continuity and a trustworthy attitude createa good relation that is based on a genuine interest of wanting to understand these youngwomen from a life-world perspective. To be able to offer these young women the supportthey are in need of it is important that the school nurse dare to be present, listen and ask the question.

    Kommunikation i kundorderprocessen: En fallstudie på OFFECCT2007Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis emphasizes the importance of efficient communication on an internal and external level as well as how an organisation should use communication in order to improve its business. Logistics is considered to be a tool for controlling different flows and it can be used to fulfil the needs and wishes of a customer. This thesis has been carried out at the furniture company OFFECCT that cooperates with internationally known designers to develop furniture for a private and public environment. A previous mapping of the orderfulfilment process at this company proved that the communication is not satisfactory. It is very important for OFFECCT as a rather small company to pull off an efficient communication on an internal and external level in order to survive on the market. Some of the reasons for focusing on communication are an increased return on investment and an improved customer service.

    The orderfulfilment process includes several activities, starting off with a need and is finished by the distribution of products and after sales service. The activities create a flow with different kinds of information that are to be sent in between the persons in charge of each activity. The kind of information can vary depending on where in the flow it is located. In order to communicate this information, a process to transmit the message is required so that an interpretation of the sent message is possible. By using different sorts of communication channels, a company can send certain information in a specific way to enhance the scattering of information. Communication and information can be either formal or informal depending on whether it is work related or not. Furthermore, communication should be carried out internal within the company and external with interested parties to obtain a solid organisation that changes with its surroundings. How well a company communicates information can be determined by a few factors such as actual distances and organisational structures.

    Observations and interviews at OFFECCT revealed a few problems within the communication aspects that cause an inferior customer service and difficulties to carry out the orderfulfilment process efficiently. An analysis of the empirical information resulted in a few ideas for improvements and a general process that can be used to improve communication, which are presented further in the thesis.

    Livs- och arbetssituationen: En enkätstudie om upplevd balans2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: In recent years, sickness absence has increased in Sweden. Something that also has become noted is how the individual manages to combine their living and working conditions. Living conditions includes everthing that happens outside paid work. Partner, children and the private economy are factors that also are included in the individuals living conditions. With working conditions means everthing that happens at work, but also events related to work. Sickness absence can be seen as a consequence of the fact that the individual is not able to balance their living and working conditions, which in turn may have an impact on the organisation. On this basis this study’s problem area was developed from a perspective that combines sickness absence and the experience of balance, between the two main areas that the individual constantly orients between.

    Purpose: The aim of this study is to examine which factors in the lifesituation that is recurring among employees who are experiencing similar degrees of balance between living and working conditons.

    Method: The methodology used in this study was a questionnaire, which was analyzed with help of an understanding interpretation. The method was choosen because of the sensitive nature of this subject, but also to keep the respondents anonymous. As mentioned, the subject of sickness absence is interesting to examine in relation to the subject of balance. Therefore the selection of respondents was based on their history of sickness absence, and formed two respondents groups: sickness absence and healthy attendence. This to investigate differences and similarities between the two groups.

    Findings: The theories of work-life balance and work-life conflict, which is about how balance and conflicts occurs between individuals living and working conditions, were used to make an understanding interpretation of respondents’ surveys. The study showed no distinctive differences regarding the experience of balance, between the respondents groups.

    The neural correlates of cognitive reappraisal stress resilience2018Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    Resilience refers to the fact that some individuals cope well with stressful experiences. Many factors contribute to this sort of resilience, such as the early environment, the serotonin transporter gene (5-HTTPLR), the hypothalamic-pituitaryadrenal (HPA) axis, the sympathetic-adrenal medullary (SAM) axis, and emotion regulation techniques. The aim of this thesis is to investigate which factors contribute to resilience, with a particular focus on the emotion regulation technique of cognitive reappraisal. The results show that the prefrontal cortex (PFC) and amygdala each play a crucial role when it comes to stress regulation. Studies have found that the PFC inhibits the amygdala response, but that the PFC is vulnerable to exposure to chronic stress. As a result, the PFC might fail to inhibit the amygdala response. Individuals who use cognitive reappraisal techniques – which has been associated particularly with frontal and parietal brain activity – seem to be less prone to this sort of problem, and, as a result, more resilient to stress.

    Agency i Förgrenande Dialogsystem: En undersökning om agency i förgrenande dialogsystem i spel2016Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Frågeställningen till den här studien undersöker hur spelare upplever agency i ett förgrenande dialogsystem med tidsbegränsade valtillfällen i jämförelse med dialogsystem utan tidsbegränsningar. I bakgrunden observeras vad agency betyder och hur begreppet används samt vad tidigare studier har lett till. Kapitlet fortsätter med att diskutera vad meningsfulla val är för något och hur en berättelse kan upplevas som trovärdig.

    För att kunna besvara studiens frågeställning skapades två olika textbaserade spel, en med tidsbegränsningar i dialogerna och en utan. För övrigt har de inga andra skillnader. Dessa användes sedan till att mäta skillnader i hur spelarna upplevde agency genom att jämföra resultatet från två olika undersökningsgrupper, en för varje version av spelet.

    Resultatet bestod av ett antal åsikter från deltagarna angående sin spelupplevelse. Skillnaderna mellan grupperna var små och mängden insamlad data var för liten för att ge något säkert resultat och frågan fick inte något pålitligt svar.

    ”Det är många som tror att det bara finns två kön”: – en studie om genuskonstruktion utanför den traditionella genusdikotomin2008Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Uppsatsens syfte är att genom ett symboliskt interaktionistiskt och ett social konstruktionistiskt perspektiv öka förståelsen för hur personer som anser att de överskrider de dikotomiska kategorierna man/kvinna konstruerar sitt genus. Samt problematisera om och hur individer kan frångå dessa kategorier i skapandet av genus. Studien grundades på sju djupintervjuer med personer som upplevde att de överskred eller inte identifierade sig med kategorierna man/kvinna. Som teoretisk grund gällande identitetskonstruktion och socialisation har vi främst använt oss av Berger och Luckmann (1991) samt tolkningar av Mead (Berg, 1992; 2007). För att få en djupare insikt kring genuskonstruktion har teorier av Butler (2007) samt Connell (2003; 1996) använts. Konstruktionen av könsidentiteten är en ständigt pågående process som är i ständigt behov av upprätthållelse. Upprätthållandet sker till stor del genom identifikation och bekräftelse samt uttryck, så som språk och yttre attribut. Då samhället har ett mycket dikotomiskt synsätt gällande kön/genus så krävs av respondenterna ett aktivt ställningstagande för att de ska kunna avvika från det normativa. Respondenterna kan dock inte helt frångå de dikotomiska kategorierna då de måste förhålla sig till dem i mötet med andra människor. Eftersom de avviker från det normativa får de också svårare att upprätthålla könsidentiteten då den inte uppmuntras av samhällsnormen och det därmed blir svårare att få bekräftelse och hitta identifikationsobjekt. Vi menar att denna uppsats ger den socialpsykologiska diskursen gällande genus, en bredare syn på identitets- och genuskonstruktion utanför normen, då vi uppfattar detta som underrepresenterat inom den socialpsykologiska forskningen.

    Dominans och undergivenhet hos spelkaraktärer: Faktorer som påverkar uppfattningen av dominans kontra undergivenhet hos animerade spelkaraktärer2016Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Denna studie undersöker hur man som animatör bör gå tillväga för att gestalta karaktärer med dominanta alternativt undergivna personligheter. Ett antal faktorer som förväntas förmedla dominans respektive undergivenhet identifieras i bakgrundskapitlet och används sedan som bas för att gestalta sex olika animationer där dessa faktorer kombineras på olika sätt. Dessa faktorer inkluderar kraftcentrumets placering, expansivitet i poser, samt Labans efforts. Undersökningen genomförs med hjälp av en online-enkät där respondenterna får svara på frågor om hur de tolkar karaktärerna. Resultatet indikerar att de identifierade faktorerna alla har betydelse för hur dominant kontra undergiven karaktärerna uppfattas.

    Building and programming an autonomous robot using a Raspberry Pi as a PLC2016Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    PLC programming students are often limited to simulated systems or soft PLCs, because the high price of the hardware and the software licenses make it difficult for faculties to use real equipment for teaching. This paper describes the design and building of a PLC controlled self-balancing robot with CodeSys and Raspberry Pi as a low-cost demonstrator model that students can use as a base to interact with a real system. A first prototype has been developed, which can be used in the future to get students involved in beginner automation courses without having to build a system from scratch.

    Ungdomars syn på sex- och samlevnadsundervisningen i skolan2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Sex och samlevnad är en av många faktorer som har betydelse för hälsa och välbefinnande hos såväl vuxna som ungdomar. Alla elever har rätt att få sex- och samlevnadsundervisning i skolan. I arbetet med att stärka ungdomars förmåga att göra medvetna och ansvarstagande val som rör sexualitet och relationer är sex- och samlevnadsundervisningen en viktig del.

    Syfte: Att beskriva hur förstaårselever på gymnasiet upplever den sex- och samlevnadsundervisning som de hade i högstadiet.

    Metod: Studien genomfördes med kvalitativ metod med induktiv ansats och data analyserades med innehållsanalys. Fyra fokusgrupper genomfördes med totalt 20 deltagare. 

    Resultat: Analysen resulterade i tre kategorier; Eleverna beskriver att sex- och samlevnadsundervisning är av stor betydelse, Att ha erfarenhet av en undervisning som upplevs bristfällig samt elevernas önskemål om förändring i undervisningen.

    Slutsats: Ungdomarna upplever att sex- och samlevnadsundervisning är viktig men att undervisningen i detta ämne också har brister. Det finns behov av att lyssna på och respektera unga människors åsikter gällande undervisningen i sex- och samlevnad. Detta för att anpassa undervisningen utifrån ungdomars livsvärld och deras behov och därmed bidra med betydelsefull kunskap i ämnet. Skolsköterskors omvårdnadsperspektiv kan tänkas bidra till den öppenhet och följsamhet för individens unika behov vilket efterfrågas av deltagarna.

    Effektiv hantering av krav under systemförvaltning2010Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    

    I ett systemutvecklingsprojekt är kravspecifikation en av de främsta nyckelfaktorerna för att åstadkomma ett system som samtliga inblandade aktörer känner sig tillfredsställda med. Teorin innehåller ett stort antal riktlinjer och tekniker som hjälpmedel i arbetet med att ta fram komplett kravspecifikation.  När ett system väl har implementerats och sats i drift är vidareutveckling, anpassning samt underhåll av stor betydelse för hur väl systemet kommer att fungera i framtiden, som präglas av förändring. Trots detta förekommer det betydligt färre rekommendationer angående hur receptet för ett lyckat systemförvaltningsarbete kan uppnås. Syftet med denna uppsats är att undersöka hur processen för att samla in krav under systemförvaltningsfasen och med vilka tekniker krav detta sker och påvisa likheter och skillnader teori och praktik emellan. Resultatet av undersökningen påvisar att systemförvaltningsarbetet gällande krav till stor del sker ad hoc, medans litteraturen förordar ett kravhanteringsarbete som kan liknas det som rekommenderas i systemutvecklingsteorin.

    Abstract [sv]

    Detta arbete ämnar undersöka vilka kroppsdelar som effektivast kommunicerar nervositet och blyghet hos en karaktär. Detta för att etablera riktlinjer för en animerare så han/hon ska veta vilken kroppsdel som det bör läggas mest tid på under produktionen. Detta genomfördes genom en stadig grund i litteratur inom ämnet kroppsspråk samt filmmaterial i form av referensmaterial. En karaktär animerades med ett kroppsspråk som tyder på ett nervöst samt blygt beteende. Sedan utvärderades de olika kroppsdelarna genom en kvalitativ undersökning där det visar sig att ansiktet var den kroppsdel kommunicerar den eftersträvande sinnestämningen effektivast. Sedan armarna samt händerna, sist benen samt fötterna. Detta resulterar i de riktlinjer som arbetet ämnar framställa.

    Abstract [en]

    This methodological article explores issues related to having the ontological ground for phenomenological empirical research present throughout the research process. We discuss how ontology needs to be taken into consideration regarding the phenomena to be studied and how ontological aspects of phenomena need to be highlighted during various data collection and analysis procedures. Here, we discuss how philosophical works can be used in the context of specific research projects. In illustrating our statements, we present four empirical examples connected to the themes of life changes and learning processes with the purpose of exemplifying and discussing how general lifeworld ontology can be integrated as an active resource in empirical phenomenological research.

    Active Capability Support for Cooperation Strategies in Cooperative Information Systems1998Doctoral thesis, monograph (Other academic)
    Abstract [en]

    One important feature for the current and next generation of information systemsis the ability to be able tocooperate. Information systems that are able to cooperateare referred to as cooperative information systems. The problem of moving the stateof the art from information systems designed asislands of automationto cooperativeinformation systems has primarly been addressed by the distributed artificial intelli-gence community and the database community. For example, the distributed artificialintelligence community has investigated cooperation strategies such as task sharingand result sharing, whereas the database community has developed techniques forinteroperability over heterogenous databases. One characteristic of cooperative infor-mation systems is that no individual solution can satisfactorily support all requiredcharacteristics of cooperative information systems. This thesis takes the position thata synthesis of results from the distributedartificial intelligence community and thedatabase community is a promising direction for developing cooperative informationsystems.In this thesis, active capability (as defined within active databases) is considered asan important core technology for cooperative information systems. Active capabilityis supported by event condition action (ECA) rules with the following semantics:when an event E occurs, evaluate condition C, and if the condition is satisfied, thenexecute action A. The applicability of using ECA rules has primarly been exploredwithin database systems and has recently initiated ECA related research within otherresearch communities such as real-time and workflow.This thesis focuses on what is required in an interface between information sys-tems when using an active capability approach to supporting the major cooperationstrategies as formulated in distributed artificial intelligence. The significance of the2work reported in this thesis concerns two major issues. First, advanced types ofcooperation strategies such as task sharing and result sharing can now span the do-mains of database and distributed artificial intelligence architectures. Second, as thiswork synthesizes and extends results from two different research communities, it pro-vides a good foundation for using active capability as one of the core technologies forcooperative information systems.

    Management of Rules in Object-Oriented Databases1994In: Proceedings of the Baltic Workshop on National Infrastructure Databases: Problems, Methods and Experiences, 1994, Vol. 1, p. 78-85Conference paper (Refereed)
    Abstract [en]

    This paper proposes a new approach to associating rules with events in object-oriented database systems. In it we propose a new run time mechanism, which associates rules with specific event definitions. This provide a basis for indexing rules by event definitions, which reduces rule checking to a minimum. The proposed subscription mechanism is general, in that it can be applied to both primitive events and composite events. Both rules and events are represented as first class objects. This architecture has been adopted in the ACOOD2 prototype on top of ONTOS.

    This paper propose a simple and powerful approach to associating rules with events in reactive object-oriented database systems. In it we propose a new run time subscription mechanism, which associates rules with specific event definitions. This brings optimization considerations - when to fire a rule - to the language level. The proposed subscription mechanism reduces rule checking to a minimum. It can be applied to both primitive and composite events. Both rules and events are represented as first class objects. This architecture has been adopted in the ACOOD2 prototype on top of ONTOS.

    Active rules (i.e., event condition action rules, triggers) have been put forward as a technique for reacting to important events, and thereby avoiding polling or embedding rule processing in applications. Despite the promises of active rules technology, the usage of active rules is low in practice. It has often been claimed (by database researchers) that the reason why few active rules applications have been built is due to the lack of support in analysis and design phases. Hence, there are very few notations or guidelines available for software engineers who develop active rules applications.In this paper, we propose modelling templates for UML state-charts and UML-A statecharts for how software engineers can capture the fundamentals of active rules. By following the proposed modelling templates and notations for active rules, it will be easier for software engineers to develop applications that rely on active rules technology.

    Extending Active Capability Mechanisms for Context Based Subscriptions1998Report (Other academic)
    Abstract [en]

    Interest has increased recently in synthesizing solutions to CIS problems by using results from the database and distributed AI communities. Such synthesis is not without its difficulties; results do not always transfer seamlessly to a new, complex domain. In this paper we highlight the difficulties encountered in our attempts to use event detection and subscription mechanisms (proposed in current active databases) for the problem of efficient result sharing in CIS. A solution to such problems is described, in the form of a refined, context based subscription mechanism.

    Extending database support for coordination among agents1997In: International Journal of Cooperative Information Systems (IJCIS), E-ISSN 0218-8430, Vol. 6, no 3-4, p. 315-339Article in journal (Refereed)
    Abstract [en]

    Coordination and collaboration are naturally used by groups for carrying out activities and solving problems that require cooperation. However, getting a set of computer agents to do the same has been a problem - primarily addressed by the AI community and recently by the database community as workflow and process management problems (for example, in business processes, electronic commerce, logistics). Not surprisingly, the problem has been addressed at different levels of abstraction by the two communities. Coordination protocols as well as task and result sharing have been investigated by the AI community; specification of alternative transaction models to meet the requirements of non-traditional applications, and their execution have been addressed by the database community. It is evident that there is a need for bringing the two approaches together to develop systems that support cooperative problem solving. This paper - argues for the use of active databases in general and active capability in particular as an enabling technology for cooperative problem solving and cooperative information systems - details a novel approach for supporting task sharing, a key aspect of CPS, using active capability - elaborates on a methodology for mapping task shared protocols expressed in high level speech acts to Event Condition-Action (ECA) rules.

    Result Sharing Among Agents Using Reactive Rules1997In: Cooperative Information Agents: First International Workshop, CIA'97, Kiel, Germany, February 26-28, 1997, Proceedings / [ed] Peter Kandzia, Matthias Klusch, 1997, p. 126-137Conference paper (Refereed)
    Abstract [en]

    This paper critically analyse the use of active databases as an enabling technology for result sharing as defined in the DAI literature. In particular, we demostrate how ECA (Event-Condition-Action) rules can be used for supporting result shared cooperation. Further, we demonstrate how composite events as defined within active databases can help a problem solving agent to precisely specify when to take responsive action to multiple result notifications.

    Coordination Among Agents Using Reactive Rules1996Report (Other academic)
    Abstract [en]

    Coordination and collaboration are naturally used by groups for carrying out activities and solving problems that require cooperation. However, getting a set of computer agents to do that same has been a problem -- primarily addressed by the AI community and recently by the database community as workflow and process management problems (e.g. in business processes, electronic commerce, logistics).

    Not surprisingly, the problem has been addressed at different levels of abstraction by the two communities. Coordination protocols (both static and dynamic) as well as task and result sharing have been investigated by the AI community; system level support as well as specification and execution of relaxed notions of transaction (sometimes termed an activity) have been addressed by the database community. It is evident that combining the two will provide an effective unified solution for a class of problems that require cooperation. This paper classifies problems addressed in the AI and database literature according to degree of coordination and collaboration. It reports on work done by the authors in utilising the reactive paradigm to synthesize, from the yechniques in these areas, a common framework for the support of multi-agent problem solving, workflow, and process management. In addition to resolving the terminology used by different groups, task sharing is used to demonstrate the approach described. It is accomplished by creating either static or dynamic plans that are coordinated by ECA rules -- both pre-defined and dynamically created. The paper details the applicability of ECA rules in this domain, their adequacy, and a prototype implementation.

    Issues in Active Real-Time Databases1996In: Active and Real-Time Database Systems (ARTDB-95): Proceedings of the First International Workshop on Active and Real-Time Database Systems, Skövde, Sweden, 9–11 June 1995 / [ed] Mikael Berndtsson, Jörgen Hansson, London: Springer, 1996, p. 142-157Conference paper (Refereed)
    Abstract [en]

    Active databases and real-time databases have gained increased interest in recent. Both active and real-time databases are considered as important technologies for supporting non-traditional applications such as computer integrated manufacturing (CIM), process control and air-traffic control. These applications are often event driven and need to react to events in a timely and efficient manner. In this paper we address the problem of merging active databases and real-time databases. Active real-time database is a fairly new area, in which very little research has been carried out so far. However, the use of active real-time database applications has a great potential. In this paper we address several issues and open questions such as semantics, assignment of time constraints and rule selection, which need to be considered when designing active real-time databases.

    Time is the Shadow of Reactive Behaviour2000In: Proceedings 2000 International Database Engineering and Applications Symposium / [ed] Bipin C. Desai, Yasuhi Kiyoki, Motomichi Toyama, Piscataway, NJ: IEEE, 2000, p. 417-423Conference paper (Refereed)
    Abstract [en]

    Applications that rely on coordination of messages are frequently based on multi-agent systems or workflow systems. Both implementation platforms use a rule engine for the coordination of messages. Currently, classical production rules are used within multi-agent systems, and workflow systems tend to rely on active database solutions (i.e. triggers). It has been envisioned that subsequent application generations are likely to require support for hundreds or even thousands of triggers. This is in contrast to the current state-of-the-art of implementations, which only scale to a few triggers. The paper outlines a vision where a scalable trigger system is the unifying concept between workflow and multi-agent approaches for applications that require coordination facilities. In particular, the paper defines scalability and performance within an active database context. The paper explores factors and situations that influence active database performance. Finally, the paper explores promising directions for how to move the state-of-the-art to trigger systems that scale to many triggers.
