    Electronic patient records in interprofessional decision making: Standardized categories and local use2012In: Human Technology, ISSN 1795-6889, E-ISSN 1795-6889, Vol. 8, no 1, p. 46-64Article in journal (Refereed)
    Abstract [en]

    Electronic patient records (EPRs) are a constitutive element of medical practice and are expected to improve interprofessional communication and support decision making. The aim of the current study is to explore the ways in which access to structured information from multiple professions within EPRs enters into the phases involved in arriving at final agreements about patients' future care. The results show that decision making in interprofessional team rounds involves a prestructuring of a pathological reality. Further, the results demonstrate how information in EPRs is deconstructed and recast into patterns that presuppose knowledge about the EPR's structural organization. This means that EPRs are highly flexible technologies and that their design does not determine their usefulness. A major conclusion is that the members' knowledge on how to bridge between standardized categories in EPRs and their local meanings is decisive for understanding the basic conditions necessary for how EPRs could support interprofessional collaboration.

    The development of mobilizing pedagogical strategies2016In: ICERI2016 Proceedings: 9th annual International Conference of Education, Research and InnovationSeville, Spain. 14-16 November, 2016. / [ed] L. Gómez Chova, A. López Martínez, I. Candel Torres, IATED Academy , 2016, p. 6923-6923Conference paper (Other academic)
    Abstract [en]

    In contemporary society, questions are often raised about the relation between education and integration of immigrants and people with a foreign background. In that context, pedagogical efforts have been made to combine educational and social interventions, emphasizing issues of inclusion, mobilization and learning processes. The overall aim in this study is to identify and explain how pedagogical strategies with respect to inclusion processes has evolved at a school for adult Roma students. Such pedagogical strategies are seen as crucial for improving immigrant conditions and opportunities and the data collection took place at a school with an outspoken Roma-profile in Sweden. In all, eight teachers and one principal were interviewed and the following research questions are addressed: What are the relevant aspects of social pedagogy in inclusion processes? How are these social pedagogical strategies distributed individually and jointly in a school context? The results show how the historical roots and theoretical foundations of pedagogical thinking and action take place as a "facilitator" and guides the teachers actions. To recognize the students cultural belonging and having a dialogical approach works as cultural bridging which actually to some extent transformed the teachers daily work from teaching to also embrace cultural broking-strategies to enforce learning processes.

    Local knowing and the use of electronic patientrecords: categories and continuity of health care2012In: Health and Technology, ISSN 2190-7188, E-ISSN 2190-7196, Vol. 2, no 3, p. 185-196Article in journal (Refereed)
    Abstract [en]

    The electronic patient record (EPR) is a constitutive element of medical practice and can be conceived of as a multi-purpose tool that is intended to support a range of activities such as planning, decision-making and evaluation. Each of these activities is quite complex in its own right. The aim of the present study is to explore how the standardized format of EPRs intervenes in the work of sustaining continuity in patients ' care. In doing this we analyse ow this standardized format contributes to structure the production and use of information concerning patients' mundane problems in the context of rehabilitation. Data consists of observations, informal interviews and video-recordings from a ward for patients affected by stroke. The results show that there is a tension between the highly uniform structures and standards for documentation in EPRs, on the one hand, and, on the other, how information is designed and put into use by care providers. When staff members use EPRs, they constantly have to contextualize what is written in relation to what they know about patients and/or the current situation. On the local level, the increasing standardization that follows the introduction of EPRs will make it even more necessary for professionals to engage in such interpretative work to close the gap between the standardized categories of the EPR and contextually relevant health care interventions. In spite of requests for increasing standardization there will always be a need to adapt to specific needs for more flexible information structures. Otherwise, there may be the risk that non-standard features the initial standardization was intended to reduce may be re-introduced.

    Feeling rejected or invited: Experiences of persons seeking care advice at the Swedish Healthcare Direct organization2014In: Japan Journal of Nursing Science, ISSN 1742-7932, Vol. 11, no 2, p. 87-93Article in journal (Refereed)
    Abstract [en]

    Aim Swedish Healthcare Direct is an organization staffed by registered nurses who act as telenurses and assess callers’ need for care, taking both medical and personal aspects into account. They direct the care seeker to: emergency care (level I), a care center on duty (level II), their regular doctor (level III), or provide advice about self-care strategies (level IV). In this assessment process, the nurse and care seeker should reach mutual agreement. The aim and focus of the present study was to elucidate the care seeker’s situation and experiences of the care received after being triaged and directed to level II, although the telenurse in fact assessed their medical problems as corresponding to level III. Methods A total of eight recent Swedish Healthcare Direct users were interviewed in this qualitative study. Data were analyzed by means of content analysis. Results Three themes emerged – “feeling trapped”, “feeling disrespected”, and “feeling invited” – comprising seven subthemes. Conclusion Care seekers experienced suffering as well as struggling to be allowed to be a patient. When not met by an ethically correct stance, they continued to seek care. In contrast, when they encountered commitment and an ethically correct attitude, their health process began and they had no further need for contact.

    Lärares uppfattningar om formativ bedömning2014Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Det förs i dag en diskussion i skolans verksamhet om formativ eller summativ bedömning är att föredra. Vi har själv stött på lärare som förespråkat användandet av den formativa bedömningsformen, såväl som de som motsatt sig densamma, under vår praktik. Med detta som grund, tillsammans med att vi själva ville undersöka om formativ bedömning är något som skulle passa oss i vår kommande yrkesroll, bestämde vi oss därför att göra en studie om lärares uppfattningar om formativ bedömning. Vårt syfte med studien var just att undersöka lärares uppfattningar om formativ bedömning i grundskolans senare år. Utifrån detta syfte formulerade vi sedan fyra underläggande frågeställningar för att begränsa vår studie. Dessa är följande:

    • Vilka fördelar kan lärarna se med formativ bedömning?

    • Hur bör man enligt lärarna använda sig av formativ bedömning för att det ska mynna ut i så positiva effekter som möjligt?

    • Vilka svårigheter kan lärarna se med formativ bedömning? 

    • Hur kan man enligt lärarna utveckla användandet av formativ bedömning inom skolans verksamhet? 

    Vi valde att använda oss av en kvalitativ metod för att genomföra vår studie. Detta för att vi ville gå mer på djupet och få en uppfattning om lärarnas tankegångar bakom sina attityder än att bara fokusera på rent mätbara fakta som man gör mer i den kvantitativa metoden. Vi valde att intervjua fem olika lärare i vår studie och intervjuerna var av semistrukturerad kvalitativ karaktär, en öppen intervjuform där man ger respondenten möjlighet att svara på sättet som han/hon vill.

    I vårt resultat fick vi fram att respondenterna genomgående ställde sig positiva till formativ bedömning. Några av de fördelar som lyftes fram var att eleverna med denna bedömningsform blir mer delaktiga i sitt eget lärande och att det blir tydligare för dem hur

    de ligger till i förhållande till kunskapskraven. Bedömningsmatriser tillsammans med

    tydlighet och struktur var några av de saker som lyftes fram som viktiga för att man ska få

    ut så mycket positivt som möjligt av den formativa bedömningen. Det som av respondenterna lyftes fram som de största svårigheterna med formativ bedömning var tidsaspekten och att hitta en balans mellan konstruktiv kritik och uppmuntran. När det gäller utvecklandet av formativ bedömning var sedan en fortbildning av lärare och kamratrespons de områden med utvecklingspotential på sikt som togs upp av våra respondenter

    USB 3 jämfört med 2.0: En jämförande studie om bulköverföringar2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Fokuset i denna studie ligger huvudsakligen på en av de fyra överföringstyper som USB 2 och 3 använder sig av, bulköverföringar. Från den valda typen av överföring kommer tider och hastighet mätas i tolv testfall. Alla testfall delas in i två grupper ett där mätningarna genomförs under tiden media strömmas ifrån en annan USB-enhet för att belasta USB-bussen. Och ett annat där bussen är obelastat. Värden visas och jämförs sedan med hjälp av grafer och histogram där medelvärden, standardavvikelser samt variationskoefficienten har tagits fram.

    Resultatet i denna studie visar att USB 3 en högre variationskoefficient i vissa lägen. Mätvärden visar att USB 3 har ett lägre variationskoefficientvärde när testdatan består av många små filer än vad det gör för USB 2. Dock ökar variationskoefficienten för USB 3 när filstorleken blir större jämfört med USB 2 som påvisar en sjunkande variationskoefficient.

    Bostadsbrist: En kvantitativ undersökning om vilka faktorer som orsakar bristen på lägenheter i Stor-Göteborg2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A report on the lack of apartments in Sweden's second largest city, Gothenburg. The study aims to analyze the causes of the housing shortage that is current in Gothenburg and how the selected factors have contributed to the lack of apartments. The study has been done quarterly between 2000 and 2017 and limited to Greater-Gothenburg, which includes the following municipalities: Kungälv, Stenungsund, Tjörn, Öckerö, Gothenburg, Mölndal, Partille, Härryda, Lerum, Ale, Alingsås, Lilla Edet and Kungsbacka. Four variables selected based on the presented scientific articles have been examined for unit roots and cointegration to further investigate its short and long-term impact on the dependent variable using an Error Correction Model. The result confirms the population, price of apartment and production cost for apartment as the most influential number of apartments in Greater Gothenburg in the long term. In the short term, the number of apartments in the form of a historical value from the previous quarter is confirmed as an important factor in explaining the current range of apartments and also the price of the apartments and the error term. All variables with the exception of the lending rate together have a high R2 value of 99.4%, which indicates a high degree of explanation of the dependent variable.

    Projektering och beredning av ett distributionsnät i ett exploateringsområde2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis is about how a preparatory works from start to finish. The project comprises a power distribution network in a new residential area with 33 villas, a preschool and an industry property. Parts that power consumption of houses, preschool and an industry has been based on their main fuse. Load current and dimensioning of low voltage cables as high-voltage cables have been developed for the different sections available cable is located. Voltage drop of the various sections for service cables and the supply cables and the voltage dips to subscribers are treated in this report, with the goal of keeping this voltage drop below 4 %. The trigger condition for the different connection routes have been checked to keep the mains as safe as possible. The economic area has been considered, for the selection of the various cables that has been used during the operation. The work also deals with the selection of materials from the cable distribution cabinets to fuses. Several different agreements have been treated, map types from the excavation map to high voltage map has been developed. In a project there are several costs which are essential to obtain the final cost. Some of these costs have been treated as: P2-calculation is made and valuation protocol for the various land owners has been developed. A presentation of the different applications used within a preparation has been included, which can help and facilitate the work of processors. The result of the preparatory works comprises a new 12/0.4 kV grid station, nine new cable distribution cabinets and 155 meters 12 kV HV cable and 4 087 meters 0.4 kV low voltage cable. Excavation distance will be 1 980 meters long, which excavate up to the property line, where the property owner is responsible for the excavation. The Grid Station has been placed strategically so that the excavation routes are minimized, and the voltage dips is held. Cable distribution cabinets have also been placed strategically to provide all subscribers with power and with the voltage dip in mind, the length of the service lines has been kept down. The cost of the project is estimated at SEK 2.1 million

    Ett levande bevis på att detta fungerar: En kvalitativ studie om psykisk ohälsa och återhämtning2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Psykisk ohälsa har blivit alltmer uppmärksammat i media. Media skildrar ofta psykisk ohälsai samband med negativa händelser. De positiva delarna såsom återhämtning från psykisk ohälsa blir inte lika uppmärksammat i media. Denna studie handlar om vilka faktorer individer med psykisk ohälsa, som befinner sig i en specifik verksamhet, upplever påverkar deras återhämtning. Metoden som användes var kvalitativ och materialet hämtades in via halvstrukturerade intervjuer. Åtta personer intervjuades för denna studie. Personerna som intervjuades kom från en och samma organisation som arbetar med individer som har psykisk ohälsa. Intervjuerna spelades in, transkriberades, analyserades och tematiserades i tre teman: gemenskap, struktur och vardag. Dessa utgör den empiriska delen. I den teoretiska delen analyseras materialet utifrån salutogenes, KASAM och delaktighet. Resultaten visar på att salutogenes, KASAM och upplevelsen av delaktighet har en positiv inverkan då det kan underlätta återhämtningen hos individer med psykisk ohälsa.

    “Ja, det är väl just därför man delar”: En kvalitativ studie om Quantified-selfers uppfattning och erfarenheter om delning av aktivitetsdata i Runkeeper2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The study's purpose was to get an insight into what it is that determines the Quantified-selfers to choose to share their activity or not. Using interviews as a method i interviewed users of the app Runkeeper to find out their experiences and opinions about sharing. Depending on whether they where sharing or not, the questions were costumized and based on it to get the right information from the right person.

    I also made a content analysis from a facebook group for Runkeeper users so i actually could see what information they choose to share. The survey showed that depending if they shared or not, there were clear differences regarding what opinions they had regarding sharing, especially of sharing, especially on social media.

    Those who shared, saw the process more like sharing with others to provide motivition, but also to take part of other training.

    Those who didn´t share saw their training as something private and kept it for themselves. At the same time they were more willing to take part of training information others shared in runkepper/social media.

    Abstract [en]

    Human and machine cooperation has been developed for a long time to improve the productivity and because of advantages of the machine work, machine will play a more and more important role in the industrial production. To some extent, machine has already changed the world. This master thesis project was to use several robots build an automatic inspection line to inspect the wheel hub using the thermography with induction method. Three different methods are created in robot studio and the method with rotation tool was implemented as a demonstrator at PTC (production technology center).

    Compare the methods with each other and consider the limitations and productivity, the method with the rotation tool is the best choice for the company. The automation line includes several robots. In another words, the designed automation line can be considered to be several robot cells. Most sensors and calibration methods are set up due to the rules to build a robot cell. All signal analysis and processing are solved in the robot studio during the simulation process. Some needed robot cell components, equipment and different tools are used from the standard ABB robot studio library. Several special tools and equipment are designed and modelled in the NX and then converted to robot studio.

    Qualitative and Critical Research in Information Systems and Human-Computer Interaction: Divergent and Convergent Paths2019Book (Refereed)
    Abstract [en]

    Qualitative and Critical Research in Information Systems and Human Computer Interaction explores the history and adoption of qualitative and critical research in Information Systems (IS) and contrasts it with the growth of similar methods/theories in Human Computer Interaction (HCI) and, to a lesser, extent Computer Supported Collaborative Work (CSCW). The supposition behind the comparison was that the areas overlap in subject matter and would overlap in methods and authors. However, marked differences were observed in the structure of publications, conferences, and on social media that led to questions about the extent to which the fields shared a common framework. The authors find that the history of each discipline reflects institutional factors that affected the respective timelines for the use of these approaches. This leads them to consider a sociological epistemic framework, which explains the differences quite well. It also supports characterizations of the culture of IS made by members, as having open paradigm and high collegiality, described as an adhocracy. The authors propose that qualitative and critical research developed interdependently in IS. Aside from institutional factors, a further difference in uptake of methods and critical framework comes from the US/Europe divide in research traditions and the political/epistemic climates affecting research in the respective regions. Research from beyond the transatlantic traditions postdates the developments covered here but is touched on at the end of the monograph. The primary goal of Qualitative and Critical Research in Information Systems and Human Computer Interaction is to better understand the ways the IS research community differentiates itself into diverse constituencies, and how these constituencies interact in the field's complex processes of knowledge creation and dissemination. Another goal is to create cross-disciplinary discussion and build on related work in the fields. This is important in the era of platforms with global reach, and the concurrent development of powerful AI and analytics capabilities that both intrude on daily life and try to emulate human intelligence.

    Qualitative and Critical Research in Information Systems and Human-Computer Interaction: Divergent and Convergent Paths2019In: Foundations and Trends® in Information Systems, ISSN 2331-1231, Vol. 3, no 1-2, p. 1-233Article in journal (Refereed)
    Abstract [en]

    Information Systems (IS) and Human Computer Interaction(HCI)–including Computer-Supported Cooperative Work(CSCW)–address the development and adoption of computingsystems by organizations, individuals, and teams. Whileeach has its own emphasis, the timelines for adopting qualitativeand critical research differ dramatically. IS used bothin the late 1980s, but critical theory appeared in HCI onlyin 2000. Using a hermeneutic literature review, the papertraces these histories; it applies academic cultures theoryas an explanatory framework. Institutional factors includeepistemic bases of source disciplines, number and centralityof publication outlets, and political and geographic contexts.Key innovations in IS are covered in detail. The rise ofplatformization drives the fields toward a common scopeof study with an imperative to address societal issues thatemerge at scale.

    Reputation Control and Theoretical Innovation in Two Academic Cultures2019In: Twenty-fifth Americas Conference on Information Systems, 2019, p. 1-10Conference paper (Other academic)
    Abstract [en]

    A meta-review of the history of qualitative and critical theory in Information Systems (IS) and HumanComputer Interaction (HCI) illustrates how source disciplines and publication outlets can filter reputation and affect methodological diversity. An academic cultures framework allows us to compare disciplines and explain different timelines for methods and theories. IS has many publication outlets, while HCI reputations depend on publication in the ACM Conference on Computer-Human Interaction (CHI). The fields deal with similar topics but are shaped by different institutional contexts. Qualitative research and critical theory arose in Information Systems during the 1980s and 1990s, while a search of HCI literature shows no critical theory until the 2000s. An open field of journals may create affordances for new approaches, whereas filtering reputation through a core conference may constrain them. The rise of platforms may blur domain distinctions through a common focus on AI, privacy and information integrity.

    Yrkeselevers erfarenheter om bedömning och återkoppling: Yrkeselevers erfarenheter om bedömning och återkoppling2015In: Forskning om undervisning och lärande, ISSN 2000-9674, E-ISSN 2001-6131, no 14, p. 6-23Article in journal (Other academic)
    Abstract [sv]

    Artikeln bygger på en intervjustudie med 70 gymnasieelever på barn- och fritidsprogrammet om deras erfarenheter av bedömning och återkoppling, vilket har fått en alltmer central roll genom att ses som processer som stärker lärandet. Yrkeselevers perspektiv på bedömning och återkoppling är ett outforskat område. Artikeln redovisar resultat om den skolförlagda delen av utbildningen. Två teman är i fokus: lärares bedömning och återkoppling samt kamratrespons. Eleverna anser att lärares återkoppling ofta är generell, att det är skriftliga uppgifter som ligger till grund för bedömning och att kunskapskravens termer är abstrakta. De flesta tycker att kamratbedömning är svårt och att det inte är deras uppgift att bedöma sina kamrater. Elevernas utsagor ger grund för att fundera över vilka slags lärandeprocesser som lärare behöver understödja, för att elever ska erfara mer delaktighet i bedömning. Den reser också kritiska frågor att diskuteras i utbildningspolitiska sammanhang.

    How identity status interviews may be used for in-depth studies of identity development: two wave longitudinal study of identity in emerging adulthood2014In: : A, 2014Conference paper (Refereed)
    Abstract [en]

    The purpose of this presentation is to illustrate how the identity status interview may be used to study process, content, and contexts of identity development. To do so we draw on published (e.g., Frisén, Carlsson, & Wängqvist, 2014; Frisén & Wängqvist, 2011; Wängqvist & Frisén, 2011) and unpublished results from a longitudinal project (GoLD) with identity status interviews (Marcia, Waterman, Mattesson, Archer, & Orlofsky, 1993) with emerging adults. The interviews focused on occupation, romantic relationships, parenthood, and work/family priorities, with 136 Swedish 25-year-olds and four years later with 124 of these participants. The semi-structured interview format and coding procedure used enable both quantitative and qualitative analyse of identity development in emerging adulthood. This mixed methods approach (e.g., Lieber & Weisner, 2010) offers opportunity to study identity development in depth. For example, quantitative analyses showed that it was much less common for the 25-year-old participants to explore issues concerning romantic relationships and parenthood than it was to explore occupational choices and work/family priorities (Frisén & Wängqvist, 2011). Further qualitative analyses revealed that compared to occupational choices issues concerning romantic relationships were viewed more as facts than as issues that need to be considered from several perspectives (Wängqvist, Frisén, Ignell, & Fernros, 2011). Similar results were found in thematic analyses of how the participants talked about parenthood (Frisén et al., 2014). In the second wave the question: If, besides from the issues relating to work and family, there was something else in their lives that were salient to their views of themselves, revealed a variety of life areas that emerging adults view as important to their sense of identity besides issues of love and work. These life areas involved, for example, watching and practicing different sports, friendships, and music. In line with other Swedish studies (Bergh & Erling, 2005) religion and politics were uncommon. Another example of the explanatory mixed methods approach is the longitudinal analyses of the interviews. These analyses have revealed that there is continued identity development among individuals whose identities appear stable in identity status. This development involved people’s approach to changing life conditions, their tendency to continue to make meaning of their experiences, and their development of a personal life direction. The conclusions from our work within GoLD are that identity status interviews combined with a mixed methods approach would be useful for in depth studies of identity development in adolescence as well as in emerging adulthood.

    Child and Adolescent Predictors of Personality in Early Adulthood2015In: Child Development, ISSN 0009-3920, E-ISSN 1467-8624, Vol. 86, no 4, p. 1253-1261Article in journal (Refereed)
    Abstract [en]

    This study investigated development of the Big Five personality traits from early childhood into adulthood. An initial group of 137 Swedish children were assessed eight times between ages 2 and 29 years. Initial decreases in extraversion leveled off in early adulthood; agreeableness and conscientiousness increased from ages 2 to 29; neuroticism initially increased, leveled off in later childhood and adolescence, and decreased throughout early adulthood; while openness to experience showed an initial increase, then decreased and leveled off in early adulthood. Individual developmental trajectories varied significantly, particularly in relation to gender. Personality traits became increasingly stable, and the fact that childhood scores predicted scores in adulthood indicated that personalities are fairly stable across this portion of the life span

    Welding of non-nominal geometries: physical tests2016In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 43, p. 136-141Article in journal (Refereed)
    Abstract [en]

    The geometrical quality of a welded assembly is to some extent depending part positions before welding. Here, a design of experiment is set up in order to investigate this relation using physical tests in a controlled environment. Based on the experimental results it can be concluded that the influence of part position before welding is significant for geometrical deviation after welding. Furthermore, a working procedure for a completely virtual geometry assurance process for welded assemblies is outlined. In this process, part variations, assembly fixture variations and welding induced variations are important inputs when predicting the capability of the final assembly.

    Val av regelverk för redovisning i mindre företag: Redovisningsprofessionens erfarenhet kring vilka faktorer som var avgörande för mindre företag vid valet mellan K2 och K32019Student paper second term, 5 credits / 7,5 HE creditsStudent thesis
    Abstract [en]

    On February 13, 2004, Bokföringsnämnden (BFN) decided on a modified direction on the work on norming. One of the reasons for this was that the regulatory framework was extensive due to previous ways of producing norms. Another reason for the decision was that since there was an opportunity for companies to choose recommendations from different norm providers, it was given the opportunity to choose which result they would like to report, which meant that information presented by the unlisted companies could be difficult to interpret. This resulted in the development of BFN's category rules, which divide Sweden's companies into four categories based on the size of the company, where each individual category has its own regulations that contain comprehensive general advice. With the introduction of these K-regulations, smaller companies can choose between the regulations K2 and K3.

    The purpose of this study is to show the accounting profession's experiences of which factors were decisive for smaller companies when choosing between these two K-regulations and to gain an understanding of how companies' accounting choices go. The study also shows the respondents' views on BFN's category rules and its impact on the reporting in smaller companies, the respondents' views on principle-based regulations and rule-based regulations as well as their views on K2 and K3, respectively.

    An interpretivist approach has been used with the intention of presenting the accounting profession's own opinions and experiences. Furthermore, a qualitative method in the form of semi-structured interviews has been used. The primary data of the study has been collected through the interviews, while the secondary data has been obtained through scientific articles, non-fiction literature and websites. The theory that has been linked to the problem area of the study, i.e. the way in which corporate account-ing choices go, are Positive Accounting Theory (PAT), Institutional Theory (IT) and research on choices between rule-based and principle-based theories.

    The study has shown that smaller companies often rely on the accounting profession's expertise and advice when it comes to accounting choices. In addition, it can be stated that many companies focus on simplicity and that they themselves need to make as small an effort as possible. The business sector and special conditions at the companies are important for how they choose. For example, certain specific accounting rules are crucial, mainly for companies with slightly more complicated conditions, such as component depreciation for real estate companies, the possibility in K3 to value financial assets at fair value and the activation ban for self-generated intangible assets that affect innovation companies.

    Generally, the accounting profession needs to be better at conveying the meaning of the different regulations to the companies, but also on informing that there actually is an opportunity to choose regulations.

    A study of Chinese consumers’ attitudes toward Volvo cars2011Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Zhejiang Geely holding Co. succeeded in purchasing Ford Motor Co’s Volvo unit, which was the hottest news in the world in 2010. Volvo needs the Chinese potential car market; Geely needs Volvo cars’ advanced technology. Such purchase arouses our interesting to conduct a research study on Chinese consumers’ attitude and intentions toward Volvo cars.

     

    Our aim with this study was to identify the most important attributes of Volvo for Chinese consumers; to analyse how Chinese consumers were influenced by other people’s opinions and to explore how Chinese culture factors such as face concern and group conformity influence consumers’ attitudes  towards Volvo.

     

    In order to find the result, we used online self-completion questionnaires and choose customers from a life insurance company in Shanghai as our sample group. From the survey result we found that Volvo is the second most favourable brand that Chinese consumers want to own in the near future. The top three car attributes for the Chinese consumers when they were going to choose a car were quality, safety and fuel economy. But they had less knowledge or beliefs that Volvo car has an advantage with those attributes. Besides that, we find that Chinese consumers’ behavioural intention of buying Volvo is influenced by family, friends, perceived behaviour control and group conformity, but there is no relationship between face concern and buying behaviour.

    Establishing Effective Communication with Chinese Vendors: when outsourcing production to China cross Chinese intermediary2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis dedicates to explore establishing effective communication with Chinese vendors for Western companies who outsourcing production to China. An effective communication with Chinese vendors refers to gain the true understanding, right decision and expected reaction from Chinese vendors, after they receive the managerial or communicational messages (e.g. contract or piecemeal instructions) sent by Western buyers/clients. Establishing effective communication with Chinese vendors is not just about communication any more, it is about the outsourcing management from a micromanagement to self-management level. Creating intercultural competence is also the core. The study has not only built up a multiple-categorised structure for analysing outsourcing management and communication, also generated three new attributes for effective communication with Chinese vendors i.e. ―cooperativeness‖, ―competency‖, ―specialisation‖, the other six are ―effective medium‖, ―timeliness‖, ―accuracy‖, ―consistency‖, ―credibility‖, and ―completeness‖. The quintessence of the research is that a New Model of ―effective communication with Chinese vendors‖ has been formed through the research. By following the model, a company can easily identify its development stage of effective communication establishment with Chinese vendors and predict its future communication and management orientation. Also the study is desirable for those entrepreneurs and academic researchers who are interested in outsourcing production or have the intent to really carry out an outsourcing strategy and project to China. Moreover the conclusions can inspire companies within similar environment to create their own effective method when outsourcing production to China.

    Improvement of Automated Guided Vehicle's image recognition: Object detection and identification2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Automated Guided Vehicle(AGV) as a kind of material conveying equipment has been widely used in modern manufacturing systems. [1] It carries the goods between the workshop along the designated paths. The ability of localization and recognizing the environment around themselves is the essential technology. AGV navigation is developed from several technologies such as fuzzy theory, neural network and other intelligent technology. Among them, visual navigation is one of the newer navigations, because of its path laying is easy to maintain, can identify variety of road signs. Compared with traditional methods, this approach has a better flexibility and robustness, since it can recognition more than one path branch with high anti-jamming capability. Recognizing the environment from imagery can enhance safety and dependability of an AGV, make it move intelligently and brings broader prospect for it. University West has a Patrolbot which is an AGV robot with basic functions. The task is to enhance the ability of vision analysis, to make it become more practical and flexible. The project is going to add object detection, object recognition and object localization functions on the Patrolbot. This thesis project develops methods based on image recognition, deep learning, machine vision, Convolution Neural Network and related technologies. In this project Patrolbot is a platform to show the result, we can also use this kind of program on any other machines. This report generally describes methods of navigation, image segmentation and object recognition. After analyzing the different methods of image recognition, it is easy to find that Neural Network has more advantages for image recognition, it can reduce the parameters and shorting the training and analyzing time, therefore Convolution Neural Network was introduced detailly. After that, the way to achieve image recognition using convolution neural network was presented and in order to recognize several objects at the same time, an image segmentation was also presented here. On the other hand, to make this image recognition processes to be used widely, the ability of transfer learning becomes important. Therefore, the method of transfer learning is presented to achieve customized requirement.

    Quality assurance of nailed pallet2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis project is about quality assurance of nailed pallet, which is suggesting and evaluating a solution able to detect unknocked nails in a pallet at the company AvenPallen.

    The company AvenPallen is responsible for the production of different kinds of wood products, and these products are usually nailed in a robot cell. Due to variation in the wood, like unevenness of the density and tilt and twist of the boards, the nail may not be completely driven into the wood. This can results in an uneven smoothness of the pallet surface, and the production is unable to meet the requirements of customers and cause waste. To solve this problem the company AvenPallen manages to seek some systems to achieve quality assurance process in nails.

    The project has suggested four possible systems for detecting unknocked nails in a pallet. The suggested systems are mechanical inspection system, optical inspection system, vision technique system and 3D laser scanning system. By consider the situation of the company AvenPallen, there has been two improved system which are: optical inspection system and shadow inspection system. The optical inspection system uses the optical sensor to measure the height of nail to guarantee the quality of pallets. The shadow inspection system uses a CCD camera and a light to get some figures to measure the height of nails to ensure the quality of pallets. The two improved systems have been evaluated through tests. A suggestion of a possible analysis system is also included in the report.

    The report will give the analysis and result for the evaluation experiments and show that the shadow inspection system is a suitable inspection system with the possibility to analyse the measured data.

    Performance evaluation and comparison of Dual-NIC computer Optiplex 780 with Cisco 2901 router2018Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [en]

    Evaluation of the dual-NIC computer Dell Optiplex 780 (henceforth referred to as PCR1) compared with Cisco 2901 router regarding performance.

    Both devices are tested to show maximum throughput with increasing numbers of parallel links. A Cisco Catalyst 2960G switch is used to provide more access ports. The software Iperf is used throughout the tests as both traffic generator and throughput measuring tool, meanwhile the software Dstat on PCR1 is used for CPU usage measuring. PCR1 and Cisco 2901 are tested separately. A few basic tests are performed in phase 1 to discover the maximum throughput between the devices' interfaces. In phase 2, additional client computers are added on one side of the router device, one pair at a time. All these clients receive max-load traffic simultaneously from a single server computer, which reside on the other side of the router. Phase 2 tests are meant to investigate how well the router devices handle max-load traffic in a situation where there are multiple clients, whether they prioritize any traffic or function abnormally.

    After both phases are done, an analysis of the collected data is presented, both devices's performance and differences between them will be analysed.

    Western images of China: media representations of Chinese attempts to invest in Saab2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this thesis is to describe Western images of China by focusing on media representations of Chinese attempts to invest in Saab. Theories of media representation, orientalism, racialization and stereotype are applied and used in the qualitative discourse analysis in order to find out if there are orientalist and racialized stereotypes in the material. The findings show that there are orientalist stereotypes and racialized stereotypes presented in the material. The analysis also sums up that China is a country whose people are represented to be adaptable and to have amazing productivity, since China has cheap labor power and lax labor law. Furthermore, China is represented as a country whose financial power is strong and solid, Western media characterizes China as a threat. Moreover, Chinese negotiators who went to Sweden to negotiate not only are represented as full of ambitions, but also they are seen as the saviors for Western companies which are on the verge of bankrupt. This thesis contributes to the literature by filling the gap about the Chinese attempts to invest in Saab, which is characterized by Western media.

    Factors that affect usage intention towards mobile augmented reality in fashion e-commerce.: A quantitative study using UTAUT2 model2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Today e-commerce is growing more and more popular. It might be because of the easy access directly from the home or workplace. It might also have to do with the continuous smartphone evolution allowing more people internet access than ever before. Augmented reality (AR) is a technology that can generate virtual objects and integrate them into the real world. When new technology such as AR enters the field of ecommerce, it is difficult to predict the consumers' response. This study will focus on the factors that are important for consumers' usage intentions towards mobile AR in fashion e-commerce. A few of these factors are how well technology provides benefits in performing certain activities, how easy it is to use technology and how enjoyable it is to use it. Based on past research, an acceptance model (UTAUT2) was adopted to examines what factors affect user's intention to use mobile AR in fashion e-commerce. PLS-SEM was used to estimate the relationship between factors in the UTAUT2 model. With the help of social media, a survey was distributed with the "snowball technique" to gather information. To limit the data, only those between the ages of 16 and 38 were allowed to participate in the survey. Towards the end of the timeframe of collecting data, there were 120 participants. Only two out of the six investigated factors had a positive impact on user's usage intentions: habit and performance expectancy.

    A Lightweight Framework for Tracing andVisualizing Real-Time Operating Systems2012Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    System tracing is a helpful method for engineersand users to know exactly what happens in an operating system,especially in real-time operating systems (RTOS), because forreal-time system, it is normally more difficult to know theperformance of hardware and software than for desktopcomputers. Although this kind of tracing tools already exist forsome commercial RTOS, it is fairly hard to see those tools forsmall or open source RTOS. Moreover, because the structure andimplementation of different RTOS varies, it is rare to find aframework that can easily be ported to those platforms. In thisthesis, a solution is presented to this general tracing problem ondifferent platforms. By using the portable framework, it ispossible to implement tracing component into a real timeoperating system by some simple reconfigurations. This platformportability feature is accomplished by separating the specificplatform logic from the logic of the tracing part. Finally, adeployment of this framwork onto a small open source real-timeoperating system—AtomThreads, running on an AVRATmega1650 – is used as a demonstration of this framework.

    Safe Human Robot Collaboration: By using laser scanners, robot safety monitoring system and trap routine speed control2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Nowadays, robot is commonly used to perform automation tasks. With the trend of low volume and customised products, flexible manufacturing is introduced to increase working efficiency and flexibility. Therefore, human robot collaboration plays an important role in automation production and safety should be considered in the design of this kind of robot cell. This work presents the design of safe human robot collaboration by equipping an industrial robot cell with SICK laser scanners, safety monitoring system and trap routine speed control. It also investigates the reliability of RGB-D camera for robot safety. This work aims to find a safety robot system using standard industrial robot for human robot collaboration. The challenge is to ensure the operator's safety at all times. It investigates safety standards and directives, safety requirements of collaboration, and related works for the design of collaborative robot cell, and makes risk assessment before carrying out the valuation. Based on literature review, it gives the concept of layout design and logic for slow down and resume of robot motion. The speed will be first reduced to manual speed and then zero speed depending on the distance between the human and the robot. Valuation and verification are made in the proposed safe solution for human robot collaboration to test the reliability and feasibility. This project realizes the automatic resume that the robot can con-tinue working without manually pressing reset button after the operator leaves the robot cell if there is no access to the prohibited area. In addition, it also adopts the manual reset at the same time to ensure the safety when people access the prohibited area. Several special cases that may happen in the human robot collaboration are described and analysed. Furthermore, the future work is presented to make improvements for the proposed safety robot cell design.

    Identifying the key source of deteriorating educational equity in Sweden between 1998 and 20142019In: International Journal of Educational Research, ISSN 0883-0355, E-ISSN 1873-538X, Vol. 93, p. 79-90Article in journal (Refereed)
    Abstract [en]

    Educational equity has deteriorated in Sweden from the late 1980s onwards. However, it is not clear what the main sources behind this trend are. The present study aims therefore to investigate the development of educational equity at different levels of the Swedish educational system inorder to identify possible sources of the change. Students' school grades and family educational background for the cohorts leaving compulsory school between 1998 and 2014 were analysed in three-level hierarchical models. Increased segregation with respect to student composition and academic outcomes across different schools was found to be the main source of the declining educational equity. The findings are discussed in the light of differentiated learning opportunities, as a result of recent school reforms in Sweden.

    Work-life balance och verkstadschefer2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Previous research suggests that to have a good relationship between work and private life it is important to experience a-good mental health and success at work. The industrial managers’ in this study were undergoing a major change at their workplace and this study found examined how five male managers’ perception of their work-life balance. One of the aims of this study was to examine how the managers’ roles at home affects work-life balance (WLB), to what degree support at home affects WLB, and the impact that a balance or a conflict could have. The study was conducted qualitatively with a semi-structured interview guide and every manager was affected by the change at the workplace. The results showed that some of the managers were experiencing work-life conflicts where others were on the other hand experiencing a good WLB. The most common reason for feeling conflict between work-life was the uneven amount of workload, which occurred to a greater extent due to the change. These periods of uneven workload caused the managers to feel less control. One of the things that caused the managers to feel frustration is that they had limited resources and authority to handle the demands at work. The situation at home also had a very big impact on whether the managers’ experienced a good WLB or not.

    The Conversation between Film and Ideology: How Wall Street and Wall Street. Money Never Sleeps promote and/or criticize financial capitalism? 2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this thesis is, within two films Wall Street and Wall Street. Money Never Sleeps, to explore characters from different levels of capitalism’s characteristics and ideological positions, what kind of society and ideological patterns the two films reflect and in which ways do the films promote and/or criticize capitalism. Theories on ideology and ideology critique are applied and used in a discourse analysis in order to compare characters of different levels of capitalism’s ideologies and characteristics over times in the films and describe what kind of society and ideological patterns the two films reflect. The outcomes show that characters’ ideologies and characteristics actually change over times in the films. And the outcomes also show that the two films generally promote capitalism by creating same model of story under different societies and ideological patterns.

    Balancing WAAM Production Costs and Wall Surface Quality through Parameter Selection: A Case Study of an Al-Mg5 Alloy Multilayer-Non-Oscillated Single Pass Wall2019In: Journal of Manufacturing and Materials Processing, E-ISSN 2504-4494, Vol. 3, no 2, p. 1-19Article in journal (Refereed)
    Abstract [en]

    The purpose of the study was to propose a strategy to assess the potential reduction of the production cost during wire+arc additive manufacturing (WAAM) based on the combination of wire feed speed (related to deposition rate) and travel speed (related to deposition time). A series of experiments, using a multilayer-non-oscillated single pass wall made of an Al-Mg alloy, was conducted. The quality of the wall was assessed through the lateral surface waviness and top layer undulation. The concepts of Surface Waviness and Buy-to-Apply indices were introduced. Initially, the range of travel speed (TS) that provided layers with acceptable quality was determined for a given wire feed speed (WFS), corresponding to a constant current. Then, the effect of the increase of production capacity of the process (though current raising, yet maintaining the ratio WFS/TS constant) on the wall quality for a given condition within the TS range was assessed. The results showed that the useful range of TS prevents too rough a waving surface below the lower limit and top surface undulation over the higher limit. However, inside the range, there is little quality variation for the case under study. Finally, simulations of deposition time were developed to demonstrate the weight of the TS on the final deposition time and wall quality as a function of a target wall width. This respective weight showed the existence of a complex and unpredictable, yet determined, power of a combination of TS, target wall geometry, and dead time between subsequent layers. It was verified to be possible to find optimized TS as a function of different target geometries.

    Exploring the use of switchback for mitigating homoepitaxial unidirectional grain growth and porosity in WAAM of aluminium alloys2019In: The International Journal of Advanced Manufacturing Technology, ISSN 0268-3768, E-ISSN 1433-3015, Vol. 104, no 1-4, p. 1581-1592Article in journal (Refereed)
    Abstract [en]

    In this work, an alternative approach to prevent unidirectional grain growth in wire + arc additive manufacturing (WAAM) is proposed and assessed, by moving cyclically the torch forward and backward, likewise the welding technique known as switchback. A series of tests were planned with CMT (cold metal transfer) process to compare three wall-like build-ups, which uses different deposition patterns, namely, in one-way direction, reverse direction, and switchback. The same equivalent travel speed and number of deposited layers were kept among them. Longitudinal sections were taken to identify the grain growth behaviour. Finally, samples were removed from the walls for porosity evaluation. The results confirmed the characteristics of unidirectional grain growth, when one-way direction condition was employed, and the break of growth direction between layers, when reverse direction was used, yet a zig-zag pattern became present. Differently, the application of switchback showed no preferential or unidirectional grain growth, suggesting less anisotropy of mechanical properties. In addition, switchback reduced porosity. © 2019, The Author(s).

    Sambandet mellan den ekonomiska tillväxten och arbetsmarknaden2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The relationship between GDP-growth and Unemployment as a two-variable equation was established by Arthur Okun in the 1960´s. The equation was later called Okun´s law because it provided a fitting description of the relation between GDP-growth and unemployment. Studies in the late 2000´s has shown that the relationship is diminishing as the markets for GDP-growth and Unemployment becomes more complex.

    This studies purpose is to examine the relation between GDP-growth and unemployment, and which form of GDP that explains unemployment levels the best. The authors of this paper will use three models, the difference version, the levels version and the gap version that each describes the relationship between various forms of GDP and unemployment. The countries the relationship will be tested for is Sweden and the U.S for the time period 2001-2018 by using quarterly data for the countries and see if the relationship differs between the countries and the plausible explanations on why it differs.

    Results from the studies show that the relationship is best described by the levels version and that the countries in this paper don´t differ a lot from each other and the studies that was conducted by Okun in the 1960´s.

    Fueling the Dragon’s Power: China’s oil trade through a lens of International politics2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this study is focus on China’s activities/policies in oil trade and security for keeping its own development. In this study, we try to analyze China’s activities and policies in oil trading through liberalism and realism, and to show out how China acted in global market related to oil consumption, production and trade in order to satisfy China’s oil requirements. In international political theories, the concept of realism and liberalism are almost completely opposite. The cases of activities and relevant data which we selected with China on oil trade are picked and analyzed by historical analysis and quantitative researches. That can ensure the credibility, applicability and correctness of data. After analysis, the findings show that Chinese central government guide by realism more than liberalism when it process the issues with oil trade. China considers from the perspective of their own interests and focus on how to maximize their own interest. From the surface, the partners of China also received interests, but the main target of China is ensure the security of the oil, and maintain the stability of the domestic energy consumption.
