    High voltage transient protection for automotive2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Electronics for automotive needs to be able to handle different situations that can occur on the power line, such as high voltage transients. ISO16750 and ISO-7637 describes different pulses and tests a system needs to be able to handle. This report compares three different protection circuits that can output +5V and +12V built for low power devices. The circuits use different techniques for protection, one that uses TVS diodes, another that uses a voltage regulator IC with built in protection. The last protection uses P-channel MOSFET’s for protection. The circuits are compared against protection, price and leakage current. The most relevant transients to test a system against are decided to be pulse1, pulse 2a and load dump. A pulse generator consisting of a pulse shaping network and a common drain amplifier is used to create the test pulses. The result shows that all the circuits could protect against pulse 2a and load dump. However, all the circuits did fail against pulse 1 due to an undersized diode for negative voltage protection. The leakage current did not exceed 4µA for two of the circuits in the temperature interval of -40°C to +100°C. All the circuits started to have high leakage current when the temperature got up to +150°C. The price for the circuits didn’t differ that much, all the circuits cost below 3 US-dollar per circuit when making 10 000 circuits. The conclusions that could be made of the results are that all the circuits could protect against pulse 1, pulse 2a and load dump if correct diode is used for negative voltage protection. The protection that builds on Pchannel MOSFET’s should be the best choice for low power devices due to its low leakage current and potential for low cost. The disadvantage is the complexity and number of components needed for the circuit. The TVS diodes should be used if low complexity and low number of components is preferred. The disadvantage is that TVS diodes gets hot if a load dump is applied and the interval between stand-off voltage and maximum clamping voltage is quite high. The study also shows that there are cheaper solutions than using TVS diodes.

    Auktorisering i system för digitalt bevarande2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose is to investigate, analyze and clarify the relationship between authorization and security policy for digital preservation system. Information security comes into focus when digital preservation systems are discussed. The handling of electronic documents in digital preservation systems is now widespread and a large part of many activities. This means that the business must ensure that it protects against the loss of information stored in the digital preservation system. Authorization and security policy are relevant to archive and information science because digital objects in digital preservation system are to be protected from unauthorized access. With a qualitative method the research will go through security policy, systems and models for access architecture. With open approach and open questions, the research will be summarized with a discussion on the most important conclusions for access management for digital preservation system, which are mainly built on roles. It is of great importance that the company uses roles and authorization levels to ensure that everyone knows with certainty what to do and what they cannot do.

    eDiscovery-samverkan för digitalt bevarande2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    To solve the problems of long-term digital preservation, there must be an interaction between man, the process and the technology. Data processing is an important step to secure the digital long-term storage of documents, and to use collaborative surfaces with common platforms, for preparation between archive institutions. In a computer network that should automatically be able to find and communicate with other equipment in the same network, we use different systems daily to open our files, which in the original file format has a "built-in" format, which in a certain way organizes data to be read and processed by a computer program. Here, the collection of the material is required to be done correctly. The need for contact areas for collaboration is great and an activity for solutions that enable, among other things, to comply with legislation on information retention is ongoing. Authorities and many companies that have not yet noticed the problem have the need for solutions.

    Transformation of business collaboration in a digital age: Towards a multi-relation perspective2019Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    The process of digitalisation is progressively transforming the way business is carried out and how enterprises collaborate. In this digital age, characterised by collaborations among a larger community of suppliers, customers, employees, and governments, all partners need to understand avariety of relations and how digitalisation transforms them. However, it is difficult to understand the multitude of unclear or even unknown relations generated by re-coordinating different types of relations in this digital age. Accordingly, this thesis contributes to the understanding of the transformation of business collaboration by exploring how collaboration can be understood in a digital age. The theoretical concepts involved collaboration, enterprise architecture, enterprise interoperability, and boundary object. These concepts enabled digging deeper into the complexity of sharing and aligning social and cultural worlds between communities of practice. The methodology employed was hermeneutics, which was suitable for understanding human activities. The study object concerned national development of data hubs for the electricity market in Denmark and Sweden, which replaced an old way of communicating point to point between companies. This was implemented in order to coordinate and manage data transactions between grid companies and electricity suppliers. The results indicated that digitalisation tends to increase the ability to manage collaboration and even closer relations among partners by clearly identifying every partner role and responsibility. Further, business collaboration appeared to transform from a traditional collaboration to a multi-relation collaboration that addressed digital age demands more comprehensively.

    Lika nödvändigt & tillgängligt som toalettpapper:: En kvalitativ intervjustudie som undersöker tillgänglighet till mensskydd för elever under skoltid, på ett urval gymnasieskolor under februari till mars månad 2019.2019Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [sv]

    Den här studien undersöker tillgänglighet till mensskydd, utifrån ett universal design-perspektiv, vid ett urval gym- nasieskolor i Sundsvall februari och mars månad 2019 samt hur eleverna upplever tillgängligheten. En kvalitativ inter- vjustudie, bestående av intervjuer med skolsköterskor och elever vid skolorna, genomfördes utifrån en noga formule- rad intervjumanual, där resultatet sedan sammanställdes. Resultatet beskrevs, tolkades och analyserades sedan innan slutsatser kunde dras. Resultatet visar på att tillgänglighet till mensskydd, vid ett urval av gymnasieskolor i Sundsvall under februari och mars månad 2019, utifrån ett universal design-perspektiv, är bristfällig.

    Algebrasvårigheter ur elev- och lärarperspektiv: Om hinder i lärandesituationer och utmaningar i undervisningssituationer2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [sv]

    Syftet med denna avhandling är att fördjupa förståelsen för algebrasvårigheter sett ur elevperspektiv och lärarperspektiv. För att studera detta har tre övergripande frågeställningar formulerats;

    - Vilka hinder för eleverna kan identifieras då kända algebrasvårigheter behandlas i lärandesituationer?

    - Hur kan dessa hinder för eleverna överkommas?

    - Vilka utmaningar för lärarna kan identifieras då kända algebrasvårigheter behandlas i undervisningssituationer?

    Fyra delstudier har genomförts och skapat underlag för att besvara dessa frågor.

    För att undersöka hinder för elever i lärandesituationer fick 37 elevgrupper diskutera några problemlösningsuppgifter i delstudie 1 och 2. Diskussionerna analyserades med avseende på övergångar mellan olika representationsformer i uppgifterna.

    I analyserna av övergångarna mellan olika representationsformer kunde flera hinder observeras. Bland annat tolkar eleverna variabler som enheter och har stora problem med det osynliga multiplikationstecknet i uttryck som t.ex. 5x. Eleverna kommer förbi dessa hinder genom att de diskuterar uppgiften med varandra. De ställer undersökande frågor till varandra och överför bland annat den algebraiska symbolskriften till naturligt språk vilket leder dem förbi dessa hinder. Läraren har dock en avgörande roll för att de ska kunna passera dessa hinder.

    För att undersöka utmaningar för lärare i undervisningssituationer analyserades lärares frågor i helklassgenomgångar med avseende på algebrasvårig-heter i delstudie 3 och i delstudie 4 analyserades hur sex grupper av lärarstudenter diskuterade och bedömde algebrasvårigheter i fem elevlösningar. Resultatet visar att lärarna ställer mest slutna frågor på lägre nivå i relation till de flesta algebrasvårigheter. Däremot var ca hälften av frågorna öppna då algebrasvårigheten kring algebraisk problemlösning behandlades.

    Resultatet om bedömning av algebrasvårigheter visar att lärarstudenterna inte diskuterade algebrasvårigheterna i uppgiften i någon större utsträckning.

    Som helhet visar mina studier att ur elevperspektiv så möter eleverna hinder då de löser algebraiska problemlösningsuppgifter. Både högstadie- och gymnasieelever har problem att förstå betydelsen av variabler och det osynliga multiplikationstecknet i t.ex. 5x. Ur lärarperspektiv så visar studierna att lärarna ställer olika typer av frågor beroende på vilken algebrasvårighet som behandlas. I bedömningssituationer diskuteras algebrasvårigheterna endast till en liten del. I avhandlingen diskuteras olika möjliga orsaker till resultatet samt ges didak-tiska implikationer om vad som behöver prioriteras i undervisningen.

    Swedish students in upper secondary school solving algebraic tasks: What obstacles can be observed?2016In: ICT in mathematics education: the future and the realities - Proceedings of MADIF 10, The tenth research seminar of the Swedish Society for Research in Mathematics Education / [ed] Johan Häggström, Eva Norén, Jorryt van Bommel, Judy Sayers, Ola Helenius, Yvonne Liljekvist, 2016Conference paper (Other academic)
    Abstract [en]

    To understand more about students’ difficulties when doing algebraic problem solving Duval’s semiotic theory and a mathematical modelling cycle are used to identify what obstacles can be observed. The results show that when the students have to perform transformations between two different semiotic representation systems – a conversion – the obstacles get visible.

    Skillnader i upphandling mellan EBR och AMA2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Today's Swedish power grid has a major need for renovation and upgrading, which gives a big investment requirement over the next few years. This makes it important to find new entrepreneurs in addition to those already available today. Find a way to become more attractive and interesting for these entrepreneurs. This report highlights two methods that outsourcer have to relate to. First method is Electrical Building Rationalization (EBR) and the other method is general material and work description (AMA). The system of EBR is a secure system based on long-term statistics from installations, renovations and maintenance. There the advantages of standardized components are that they are cost-effective and create a quality of work performed. AMA is a reference tool for building projects from scratch. It's freer in its structure when planning a facility. One does not need relate to more strict approach. This report looks at the differences in EBR / AMA and looks at what are good changes to attract new actors in the market. What can be changed in the future and at the same time affecting projecting design and procurement documentation.

    Hook Breathing Facilitates SaO2 Recovery After Deep Dives in Freedivers With Slow Recovery2019In: Frontiers in Physiology, ISSN 1664-042X, E-ISSN 1664-042X, Vol. 10, p. 1-8, article id 1076Article in journal (Refereed)
    Abstract [en]

    To facilitate recovery from hypoxia, many freedivers use a breathing method called “hook breathing” (HB) after diving, involving an interrupted exhale to build up intrapulmonary pressure. Some divers experience a delay in recovery of arterial oxygen saturation (SaO2) after diving, interpreted as symptoms of mild pulmonary edema, and facilitated recovery may be especially important in this group to avoid hypoxic “blackout.” We examined the influence of HB on recovery of SaO2 in freedivers with slow recovery (SR) and fast recovery (FR) of SaO2 after deep “free immersion” (FIM) apnea dives to 30 m depth. Twenty-two male freedivers, with a mean (SD) personal best in the discipline FIM of 57(26) m, performed two 30 m deep dives, one followed by HB and one using normal breathing (NB) during recovery, at different days and weighted order. SaO2 and heart rate (HR) were measured via pulse oximetry during recovery. The SR group (n = 5) had a faster SaO2 recovery using HB, while the FR group (n = 17) showed no difference between breathing techniques. At 105 s, the SR group reached a mean (SD) SaO2 of 95(5)% using HB, while using NB, their SaO2 was 87(5)% (p < 0.05), and 105–120 s after surfacing SaO2 was higher with HB (p < 0.05). In SR subjects, the average time needed to reach 95% SaO2 with HB was 60 s, while it was 120 s at NB (p < 0.05). HR was similar in the SR group, while it was initially elevated at HB in the FR group (p < 0.05). We conclude that HB efficiently increases SaO2 recovery in SR individuals, but not in the FR group. The proposed mechanism is that increased pulmonary pressure with HB will reverse any pulmonary edema and facilitate oxygen uptake in divers with delayed recovery.

    Tillämpning av blockchain inom food supply chain management2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: As a result of food supply chain management, we have access to fresh food from all around the world. But there are some encounters that food supply chain has to deal with. The E. coli outbreak in the US is an illustrative of a widespread problem faced by the food supply chain.

     

    Purpose: The purpose of the study is to examine how blockchain technology can be used in food supply chain management and see what the interest of the customer looks like.

     

    Method: The methodology of the research to examine how blockchain can be used in food supply chain management was through literature study, and questionnaire to get a better grasp of the customers interest.

     

    Result: By using blockchain technology in food supply chain management it improves the information flow, while becoming more transparent between the actors. Blockchain technology improves the security of FSCM and traceability of a product. You can automatize several processes of FSCM by using smart contracts and sensors. From the survey it was a found that there is an interest in the customers side and about two-thirds of the customer might pay extra if the products use blockchain technology.

     

    Conclusion: Blockchain’s features makes it ideal to be integrated in the food supply chain management, as it makes it harder to counterfeit the products, and it improves the trust between the actors by ensuring transparency of the information flow. But on the other hand, blockchain is not suitable for everyone, as it’s a complicated system and it can result in high switching cost when changing systems.

    Språk- och kunskapsutvecklande arbetssätt: Observationer och intervjuer av fyra lärare på högstadiet2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna studie är att undersöka hur lärare på en högstadieskola i Västra Götalands län i Sverige arbetar på ett språk- och kunskapsutvecklande sätt. Två mer specifika frågeställningar är: 1. Hur arbetar lärare på ett språk- och kunskapsutvecklande sätt? 2. Vilka hjälpmedel använder lärare för att kon-textualisera undervisningen? I studien har en kvalitativ metod använts, där fyra lärare har intervjuats och observerats. Resultatet av observationerna och inter-vjuerna ger svar på det övergripande syftet. Det sätt på vilket lärarna arbetar på i fråga om ett språk- och kunskapsutvecklande arbetssätt varierar i utifrån den språkinriktade undervisningens tre grundprinciper: kontext, interaktion och språklig stöttning. Det beror även på var läraren vill att eleverna ska befinna sig enligt Cummins fyrfältsmodell, som visualiserar och illustrerar den kontextuella och kognitiva dimensionen av lärande som grund. Det framgick även att det hjälpmedel som lärarna främst använder för att kontextualisera undervisningen är datorn och Google Classroom. Slutsatsen är att lärare 3 gav minst kontext, interaktion och språklig stöttning i undervisningen medan lärare 1, 2 och 4 upp-fyllde mer punkter enligt ett observationsschema.

    Dataöverföring mellan PLC och trådlös enhet2019Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of the study has been to analyze production-related tech-nology to develop a cost-effective solution for data transmission be-tween the machine's control systems and wireless devices.

    The reason why wireless methods were chosen for the work was to be able to repair the various donors' faults and to intervene in the sensors in real time.

    When using a portable device, the fault must be repaired and tested on the machine.

    The survey also involves developing a suitable method for wirelessly transmitting collected measurement data to the server's environment where measurement data is to be stored in order to present later charts, tables and use measurement data for statistical calculations.

    The recommended methods to be examined should then be applied in a production environment with high quality safety requirements.

    The reason for this is to minimize production stoppages in connection with qualified repair.

    Many SMEs cannot afford to invest in expensive technology, which in turn needs to be regularly updated to accommodate new equipment, platforms and training maintenance staff

    For them, it may be good to install a cheap system that can be easily installed and implemented in its existing financial control system with minimum costs using independent branded goods.

    The results of a system survey have shown that data transmission with certain methods that require less security requirements and high energy consumption becomes more unstable and more susceptible in the future.

    Seen from the other side of the border: Press coverage of the 2016 US presidential election campaign in Canada2018Report (Refereed)
    Abstract [en]

    This report analyses how the press in Canada covered the 2016 US presidential election campaign. In addition, the results obtained in this work are compared with findings from a similar study which focused on three European countries, namely, Sweden, Italy and the UK. The report is based on a quantitative content analysis of four newspapers which are The Globe and mail, Toronto star, La Presse and Le Journal de Montréal. The content analysis was carried out at the DEMICOM research centre, Mid Sweden University. The findings show among others that the horse race and scandals frames largely dominated the Canadian press coverage of the 2016 US presidential election campaign. Furthermore, the results prove that the Republican party candidate, Donald Trump was given more attention in the Canadian media than his challenger from the Democratic party, Hilary Clinton. On this aspect of media attention, the results were similar in Canada, the UK, Italy and Sweden. However, contrarily to the UK and Italy, the Canadian press was more neutral in tone in its coverage of the candidates.

    Moving Beyond Internal Affairs: Making Sense of Principals' Leadership Practices in Collaboration for School Improvement2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The thesis takes its point of departure from the recent interest in collaboration and networking as major school improvement strategies and the school leader’s crucial role in these processes. Educational research indicates that if schools are to meet future demands, then leadership must rest on trust within the organisation and a principal’s leadership must be understood in the frame of professional collaboration and social learning. The aim of this thesis is to, from an institutional perspective, deepen the understanding of regulative, normative, and cultural‐cognitive aspects of school leaders’ practices in collaboration beyond school at the local school level.

    The research undertaken in this thesis is a part of a larger research and school improvement project. This longitudinal study draws on data from a qualitative case study of three schools conducted over three years. Qualitative data including semistructured interviews, a part of a questionnaire to participating teachers with open‐response questions, and observations were used. Additional contextual data, such as field notes, document analysis, and project meeting notes were also used. The theoretical framework is based on institutional perspectives on organisations and sense‐making theory, used to provide an understanding of how principals and teachers make sense of principal leadership practices.

    This thesis builds on four separate papers (I‐IV) with their own aims and research questions but with the common goal of providing answers to the overall aim and research questions of the study. The four papers are complemented by this introductory part that ties them all together. Paper I, “Internationalization as an internal capacity builder for school improvement: a case study”, examines if and how the work with internationalization can build internal capacities for school improvement, but also examines the meaning of a principal’s leadership in relation to the work with professional collaboration and social learning. Paper II, “Collaboration With Private Companies as a Vehicle for School Improvement ‐ Principals’ Experience and Sense‐Making,” elaborates on principals’ experiences and sense‐making of a school collaboration with private companies from the local community of the school, focussing on leadership and school improvement. Paper III, “Making Sense of External Partnerships: Principals’ Experiences of School‐University Collaborations,” examine principals’ sense‐making of a school–university collaboration. Paper IV, “Teachers Making Sense of Principals’ Leadership in Collaboration Beyond School,” aims to create a deeper understanding of collaborations beyond the school with a focus on principals’ leadership and of how such processes reshape regulative, normative, and cultural‐cognitive aspects (Scott, 2008). The role of the formal leader is addressed in all four papers.

    Finally, the findings show that the principals have had the possibility to build professional capacity in their schools, create a supportive organization for learning, and connect with different external partners as a result of these beyond‐school collaborations. The different actors in the beyond‐school collaborations also became a part of the schools’ overall distributed leadership practices. The findings show that beyond‐school collaboration influences and affects the normative and cultural‐cognitive aspects that exist in the participating school to some extent. The development of collective commitments to guide collaboration, engagement in collaborative work, an increase in shared responsibility for work, and the fostering of learning‐oriented collaboration and research‐based knowledge construction are examples of norms and values that seem to have started to move during the various beyond‐school collaborations. From the cultural‐cognitive aspect, the study shows that aspects of this dimension appear more or less in the schools. The principals have interpreted and made sense of the value of beyond school collaboration in different ways. The cultural‐cognitive aspect also seems to affect the teachers somewhat, where they make sense of the importance of the formal leader in beyond‐school collaboration. They also emphasise the importance of having a pedagogical leader. The findings showed that there were challenges that became visible in the various beyond‐school collaborations. However, being aware of the challenges and broadening professional learning communities through collaboration that goes beyond school all in all seem to support the principals in their leadership practices at the local school level and also support development in a school’s practices.

    Using Spectral Descriptive Signatures for Industrial Plume Detection2012In: WSEAS Transactions on Environment and Development, ISSN 2224-3496, Vol. 8, no 4, p. 120-132Article in journal (Refereed)
    Abstract [en]

    This paper presents a novel approach for anomaly detection base on computing and utilizing descriptive spectral signatures. The goal of the work is to distinguish between contaminated and normal water areas within a region of investigation. A site-independent approach was developed by considering descriptive spectral signatures characterising normal sweat lake water as reference spectral features. Thereafter, it was possible to detect and determine the distribution of industrial outlet plumes which usually have spectral characteristics that deviate from the surrounding unaffected normal waters. The method was evaluated on airborne hyperspectral remotely-sensed image-data acquired over the region of Norrsundet, Sweden. In this region, areas of different water types were found, such as riverine sweet water, coastal salt seawater, as well as waste water discharged from paper-pulp industries. The work aimed at identifying these types of waters and their distributions. The needed reference descriptive spectral signatures of uncontaminated normal water were generated by using a dataset consisting of laboratory measurements of chlorophyll-a and phaeophytine-a concentrations and the corresponding field reflectance spectra collected at 22 sampling stations in Lake Erken, Sweden. The final results, showing the locations and distributions of contaminated and normal water areas, are in full agreement with field observations in the investigated region.

    Using Homo-Separation of Variables for Solving Systems of Nonlinear Fractional Partial Differential Equations2013In: International journal of mathematics and mathematical sciences, ISSN 0161-1712, E-ISSN 1687-0425, Vol. 2013, p. 8-Article in journal (Refereed)
    Abstract [en]

    A new method proposed and coined by the authors as the homo-separation of variables method is utilized to solve systems oflinear and nonlinear fractional partial differential equations (FPDEs). The new method is a combination of two well-establishedmathematical methods, namely, the homotopy perturbation method (HPM) and the separation of variables method. Whencompared to existing analytical and numerical methods, the method resulting from our approach shows that it is capable ofsimplifying the target problem at hand and reducing the computational load that is required to solve it, considerably.The efficiencyand usefulness of this new general-purposemethod is verified by several examples, where different systems of linear and nonlinearFPDEs are solved.

    Exact Solution of Time-Fractional Partial Differential Equations Using Sumudu Transform2014In: WSEAS Transactions on Mathematics, ISSN 1109-2769, E-ISSN 2224-2880, Vol. 13, p. 142-151Article in journal (Refereed)
    Abstract [en]

    Abstract: In this study, we propose a new algorithm to find exact solution of nonlinear time- fractional partialdifferential equations. The new algorithm basically illustrates how two powerful algorithms, the homotopy pertur-bation method and the Sumudu transform method can be combined and used to get exact solutions of fractionalpartial differential equations. We also present four different examples to illustrate the preciseness and effectivenessof this algorithm.

    Abstract [en]

    In this study, the Homo-Separation of Variables method is introduced to find the exact solution of somecoupled nonlinear partial differential equations. This analytical method is a new combination of two powerfuland popular methods; namely the homotopy perturbation method (HPM) and the separation of variables method.The exact solution is constructed by choosing an appropriate initial approximation in addition to retaining onlythe first term of the series obtained by HPM. The proposed method is capable of reducing the computational loadconsiderably when compared to other classical method.

    Development of an evidence-based decision aid on complementary and alternative medicine (CAM) and pain for parents of children with cancer2019In: Supportive Care in Cancer, ISSN 0941-4355, E-ISSN 1433-7339Article in journal (Refereed)
    Abstract [en]

    Purpose: To develop an evidence-based decision aid for parents of children with cancer and to help guide them in the use ofcomplementary and alternative medicine (CAM) for cancer care.

    Methods: This study had a mixed research design. The needs of parents were investigated by survey and focus group. Asystematic review and meta-analysis were performed on the effectiveness of CAM using Grading of RecommendationsAssessment, Development and Evaluation (GRADE). Clinical experts were interviewed and a decision aid on CAM treatmentfor pain was developed.

    Results: Parents emphasized the importance of reliable information on CAM, focusing primarily on communication and a broadspectrum of complaints related to cancer treatment. The decision aid on CAM for pain included five modalities based on 11randomized control trials (RCTs): hypnotherapy, mind-body techniques, massage, healing touch, and music therapy. Metaanalysis could be performed on hypnotherapy, which significantly reduced cancer-related procedural pain compared withstandard care (MD, − 1.37; 95% CI, − 1.60, − 1.15; P < 0.00001) and attention control (MD, − 1.13; 95% CI, − 1.34, − 0.94;P < 0.00001), and massage, demonstrating no effect on pain compared with standard care (MD, − 0.77; 95% CI, − 1.82, 0.28;P = 0.15). Research evidence and supplementary information from clinical practice and patient were incorporated in a websitebased decision aid.

    Conclusions: An evidence-based decision aid was developed to support parents of children with cancer in making decisions aboutCAM for pain management. Next steps will be to expand the website to include additional childhood cancer-related complaintsand to evaluate its use in practice

    Material identification using X-ray diffraction2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study reviews the theoretical and experimental aspects of the X-ray diffraction (XRD) technique and evaluates its use in identifying toxic elements or compounds in waste that has been incinerated. Many industries incinerate materials that contain large significant amounts of toxic elements, and these elements should be identified and re-moved to reduce environmental pollution. The aim of this project is to identify the elemental content of an incinerated ash sample, and to recommend a proper identification method when using XRD. Here, we test two ash samples (raw ash without any treatment and ash that has been stabilized by washing) using the software DIFFRAC.EVA that is integrated into Bruker’s diffractometer D2Phaser to match different diffraction patterns to identify the contents of the ash sample. Finally concluding the results XRF is more suitable than XRD for ash surveil-lance.

    Four decades of research on quality: summarising, Trendspotting and looking ahead2019In: Total quality management and business excellence (Online), ISSN 1478-3363, E-ISSN 1478-3371Article in journal (Refereed)
    Abstract [en]

    The purpose of this paper is to identify and depict the key areas around which research on quality has orbited during the past 37 years. Additionally, this paper aims to explore longitudinal patterns and trends in the identified key areas. Thereby, this study aims to present new perspectives on the foundational elements and evolutionary patterns of research on quality as well as future directions. The paper applies data- and text modelling methodology to a chronological dataset covering 37 years and consisting of scientific journals specialising in research on quality; it also includes scientific journals with a broader spectrum of operations management (OM) research. The study identifies seven central topics around which research on quality has centred during this time period: Service Quality & Customer Satisfaction; Process design & Control; ISO Certification & Standards; TQM - Implementation, Performance & Culture; QM - Practices & Performance; Reliability, Costs, Failure & Problems and Excellence - BEMs, Quality Awards & Excellence in Higher Education. The results also show that the total number of entries has risen constantly since 1980; however, there was a period of decline between 2000 and 2012, indicating that after almost four decades, research on quality is still vibrant and relevant.

    The Magnitude of Diving Bradycardia During Apnea at Low-Altitude Reveals Tolerance to High Altitude Hypoxia2019In: Frontiers in Physiology, ISSN 1664-042X, E-ISSN 1664-042X, Vol. 10, p. 1-12, article id 1075Article in journal (Refereed)
    Abstract [en]

    Acute mountain sickness (AMS) is a potentially life-threatening illness that may develop during exposure to hypoxia at high altitude (HA). Susceptibility to AMS is highly individual, and the ability to predict it is limited. Apneic diving also induces hypoxia, and we aimed to investigate whether protective physiological responses, i.e., the cardiovascular diving response and spleen contraction, induced during apnea at low-altitude could predict individual susceptibility to AMS. Eighteen participants (eight females) performed three static apneas in air, the first at a fixed limit of 60 s (A1) and two of maximal duration (A2-A3), spaced by 2 min, while SaO(2), heart rate (HR) and spleen volume were measured continuously. Tests were conducted in Kathmandu (1470 m) before a 14 day trek to mount Everest Base Camp (5360 m). During the trek, participants reported AMS symptoms daily using the Lake Louise Questionnaire (LLQ). The apnea-induced HR-reduction (diving bradycardia) was negatively correlated with the accumulated LLQ score in A1 (r(s) = -0.628, p= 0.005) and A3 (r(s) = -0.488, p = 0.040) and positively correlated with SaO(2) at 4410 m (A1: r = 0.655, p = 0.003; A2: r = 0.471, p = 0.049; A3: r = 0.635, p = 0.005). Baseline spleen volume correlated negatively with LLQ score (r(s) = -0.479, p = 0.044), but no correlation was found between apnea-induced spleen volume reduction with LLQ score (r(s) = 0.350, p = 0.155). The association between the diving bradycardia and spleen size with AMS symptoms suggests links between physiological responses to HA and apnea. Measuring individual responses to apnea at sea-level could provide means to predict AMS susceptibility prior to ascent.

    Mapping the concept, content and outcome of wilderness therapy for childhood cancer survivors: protocol for a scoping review2019In: BMJ Open, ISSN 2044-6055, E-ISSN 2044-6055, Vol. 9, no 8Article in journal (Refereed)
    Abstract [en]

    Introduction: Long-term childhood cancer survivors are at risk for frailty and have significant health-related issues in adulthood. Various health promotion interventions have been proposed to enhance quality of life including wilderness therapy, which applies the impact of nature on health in a therapeutic context. Previous studies have described positive outcomes linked with various wilderness-related therapies for cancer survivors. However, there is no clarity on the role these therapies play in childhood cancer. The current scoping review aims to systematically map the concept, content and outcome of wilderness therapy for childhood cancer survivors.

    Methods and analysis: This review will be guided by the Joanna Briggs Institute Reviewers’ manual for scoping reviews. A systematic literature search using medical subject headings (MeSH) and text words related to wilderness therapy and childhood cancer survivors will be performed in EMBASE, ERIC, Medline, Psycinfo, CINAHL, Scopus, Web of Science, SPORTDiscus and Svemed+, Sociological Abstracts, supplemented by grey literature searches. Eligible quantitative and qualitative studies will be screened, included, assessed for quality and extracted for data by two reviewers independently. Results will be described in a narrative style, reported in extraction tables and diagrams, and where appropriate in themes and text.

    Ethics and dissemination: This study describes a protocol for a scoping review that will undertake secondary analysis of data already published in literature and is therefore exempt from medical ethical review. The scoping review will inform understanding of the benefits and risks of wilderness therapy for childhood cancer survivors, their families, practitioners, clinicians and researchers, and will help elucidate the steps necessary for building its evidence base going forward. Results will be published in a peer-reviewed scientific journal.

    Lika för alla?2019In: ARKIV. Tidskrift för samhällsanalys, ISSN 2000-6225, E-ISSN 2000-6217, no 10, p. 71-86Article in journal (Refereed)
    Abstract [sv]

    När Moderaterna inför riksdagsvalet 2018 lanserade sin nya valslogan ”Lika för alla” var det till mångas förvåning, även inom partiet självt, eftersom den förde tankarna till idén om social jämlikhet, vilket vanligtvis förknippas med den politiska vänstern. I sin artikel visar Christian Gerdov emellertid hur det inom kort klargjordes att det inte var social jämlikhet som Moderaterna avsåg, utan snarare hur talet om lika för alla grundade sig i den liberala föreställningen om jämlikhet i frihet, liksom jämlikhet inför lagen. Vidare låg vikten vid skyldigheter, såsom plikten att arbeta. De sociala rättigheterna, som vann insteg efter andra världskriget, har ersatts av det nyliberala projektet för valfrihet, där medborgaren förvandlas till en självförverkligande entreprenör. Det universella subjektet i talet om lika för alla visar sig även vara partikulärt, eftersom svenskhet och svenska värderingar betonas och kontrasteras mot det hotfulla ”Andra”. Moderaternas slogan påminner därför om Orwellskt nyspråk där alla förklaras vara jämlika, men där somliga är mer jämlika än andra.

    Islands of Identity: History-writing and identity formation in five island regions in the Baltic Sea2015 (ed. 1)Book (Refereed)
    Abstract [en]

    Gotland, Åland, Saaremaa, Hiiumaa and Bornholm are five island regions in the Baltic Sea which constitute, or have until recently constituted, provinces or counties of their own. Combining perspectives from two disparate academic fields, uses of history and island studies, this book investigates how regional history writing has contributed to the formation of regional identity on these islands since the year 1800. The special geographic situation of the islands-somewhat secluded from the mainland but also connected to important waterways-has provided their inhabitants with shared historical experiences. Due to varying geographic and historical circumstances, the relationship between regional and national identity is however different on each island. While regional history writing has in most cases aimed at integrating the island into the nation state, it has on Åland in the second half of the 20th century been used to portray its inhabitants as a separate nation. Dramatic political upheavals as the World Wars has also caused shifts in how regional history writing has represented the relationship to the mainland nation state, and has sometimes also resulted in altered national loyalties.

    PLC-simulering: Virtuell balningslinje i felsökningssyfte2019Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Valmet do not have a method for testing the functionality of the control systems for the conveyors they deliver with their baling lines, as a result a lot of time is spent troubleshooting on site. They therefore seek a method which allows them to simulate these control systems to find and fix any faults in the code before delivery. Printed literature and articles published in scientific journals have been the foundation to the conducted study presented in this report. A code for a control system was provided and studied to gain understanding of its functionality. To simulate, a model which represents and behaves like the system to be simulated is required. If the simulation is to useful the model must be a sufficiently accurate representation of reality. A simulation has many advantages, it can prevent delays, save money, improve working conditions and safety. A concept for simulating this control system was developed during this thesis work. The concept overwrites the values of the physical sensors before the control logic. Every conveyor is simulated individually. The simulation has a function which saves the position of the virtual bale along the conveyor. The simulation is visualized in an HMI where the movement of the bales can be followed. The concept showed to worked very well to simulate the provided code. A large amount of the simulation should be possible to reuse when simulating other types of conveyors. Whether the concept will be able to detect faults in the code are though not confirmed, but most likely. The conclusion that can be drawn from the developed concept is that it has potential to simulate this type of control system if it is developed further, in which case the commissioning will be reduced.

    Att spara eller inte spara: De svenska arkiven och kulturarvet 1970–20102019 (ed. 1)Book (Other academic)
    Abstract [en]

    In this book, ideas and practices on appraisal in Swedish state archives c. 1970–2010 are analysed. What records has been kept, why, and for whom? How has the archival sphere been influenced by overall societal ideas on heritage and memory? The relative importance of legal and institutional frameworks is also analysed, since laws heavily regulate archives in the Swedish public sector. The Swedish Archives Act of 1990 emphasises that the “research interest” has to be accounted for when deciding what to preserve, and it adds that the state archives are part of the “national heritage”. How is this implemented in actual appraisal practises? It is shown that appraisal in Sweden is generally pragmatic and – in a Schellenbergian tradition – rests on a presumption (most often not articulated) that it is possible to foresee the desires of future users.

    I Ruriks fotspår: Om forntida svenska österledsfärder i modern historieskrivning2012 (ed. 1)Book (Refereed)
    Abstract [sv]

    Vikingatiden finns överallt: läktarna fylls av vikingahjälmar när det är landskamp, runtomkring i Sverige grundas vikingabyar, och i vår alltmer kommersialiserade historiekultur hävdas att vikingaarvet ska hjälpa oss att locka turister till Sverige. Vikingatiden är också ideologiskt laddad som få historiska epoker. Den har setts som en period när Sverige på allvar framträdde som ett eget rike, och när svenskarna för första gången gjorde sig bemärkta i andra länder. Inte minst for de österut, och tack vare arkeologiska fynd och 1100-talsskriften Nestorskrönikan har lärda och vetenskapsmän i Sverige och andra länder hävdat att Ryssland grundats av svenskar.

    I boken I Ruriks fotspår: Om forntida svenska österledsfärder i modern historieskrivning studerar historikern Samuel Edquist hur skandinavernas vikingafärder i österled beskrivits av svenska forskare igår och idag. Vi får följa utvecklingen från 1800-talets besatthet vid att finna ursprunget till våra tiders nationer i forntiden, och hur denna nationalism genomsyrade forskningsresultaten, till våra dagars försök att göra upp med vetenskapens nationalistiska förflutna. Studien avslutas med en diskussion om tänkbara strategier för att förhålla sig till en så ideologiskt laddad företeelse som vikingatiden.

    Overfishing, social problems and ecosocial sustainability in Senegalese fishing communities2019In: Journal of Community Practice, ISSN 1070-5422, E-ISSN 1543-3706Article in journal (Refereed)
    Abstract [en]

    This study explores living conditions of people in Senegalese fishing communities in relation to environmental change and unregulated fishing by foreign boats, weakening local opportunities and increasing forced migration of youth, creating problems for the future development of local fishery communities. It employs a postcolonial perspective and analyzes data collected through interviews with individuals from Senegalese fishing communities, social workers and relevant documents. The results show local reactions based on alliances between social workers and local community members to overfishing and the need for national and global structural changes. It is argued that EU’s fishing agreements with Senegalese government is one of the reasons behind youths’ forced migration to EU countries and that the betterment of the living conditions of fishery communities in Senegal requires not only already emerging alliances between social workers and local community members, but also national and global structural changes to protect Africa’s fishing communities and local fisheries.

    Suicidal ideation and severity of distress among refugees residing in asylum accommodations in Sweden2019In: International Journal of Environmental Research and Public Health, ISSN 1661-7827, E-ISSN 1660-4601, Vol. 16, no 15, article id 2751Article in journal (Refereed)
    Abstract [en]

    Refugees worldwide suffer high levels of distress and are at increased risk for death by suicide. The Refugee Health Screener (RHS) was developed to screen for emotional distress among refugees and can be used to assess distress severity. This paper examines the association between distress severity and suicidal ideation in a sample of refugees residing in asylum accommodations. Data from the RHS and item 9 on the Patient Health Questionnaire-9 (PHQ-9) was analyzed. Results showed that individuals at moderate and severe levels of distress were much more likely to exhibit suicidal ideation than individuals with low levels of distress. Even though we cannot conclude that individuals with low levels of distress do not have thoughts of ending their lives, further suicide assessment is warranted in asylum seekers with moderate to severe distress on the RHS.

    Den agila religionen, är du troende?: En kvalitativ studie om det agila arbetssättet och påverkan på organisationskultur som råder2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Agile is a work method that involves a higher degree of flexibility and adaptability for organizations, which is to be met by empowered employees. Previous research regarding agile has focused on its benefits and to a certain degree also the difficulties in its implementation, but despite the agiles’ close connections to organizational culture according to our literature review that these two fields have to a wider extent not been given a qualitative and deeper analysis together, where focus is given to how agile is viewed as an organizational model outside the IT sector. This has been researched through seven semi-structured interviews with individuals with managerial roles within different organizations, where after the results have been analyzed from the standpoint of the study’s purpose and compared to earlier research. The respondents seem to display a positive attitude toward the agile and an awareness of the importance of organizational culture in organizational change. Then a final discussion and conclusion is made where the argument is put forth that the vagueness and ambiguity which tend to surround the agile as well as organizational culture could be an essential reason to why agile is not implemented to a wider extent.

    Allt är inte sagt bara för att en lag har talat: En kvalitativ dokumentstudie om hur insiderlagen i praktiken kan ses som en spelregel2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Nyckelord: Värdepappersreglering, asymmetrisk information, abstrakta system, abstrakt förtroende, spelregel, spelAbstractInsider trading regulation is a highly-debated topic which often leads to black headlines in the media. Attempts to counteract insider trading is based on the asymmetric information that is common in the securities market and which seems to be the reason why the market can be perceived as unfair and immoral. Insider trading regulation has thus been considered necessary, but the law itself has been questioned when it comes to its real function and efficiency. Earlier research namely shows that the law may be better understood as a game rule where the game is amoral. How the law practically can be better understood as a game rule seems however yet to be lacking in previous research. A study comparing insider law with economic crimes, such as fraud offenses, has thus been considered necessary to determine in which ways the insider law can be compared to an amoral rule of law. This qualitative document-study thus aims to analyze and describe the insider law in a social constructive approach and in what ways it practically can be better understood as a game rule. The importance of maintaining trust in the securities market has also been emphasized by the supervisory authorities Ekobrottsmyndigheten and Finansinspektionen, therefore it was also considered interesting to study documents from their respective websites. The documents were analyzed based on a content analysis where the results were linked to securities regulation and insider law, trust in its abstract form and insiderlaw and/or game rules. The results of this study indicate that the insider law practically should be better understood as a game rule as insider trading is a victimless crime where there are difficulties in proving that a crime actually has been committed.

    Gendered Interventions: Changes in Visual Art Education in Sweden: Discourses, Practices and Materiality2019In: Synnyt/Origins. Finnish Studies in Art, ISSN 1795-4843, E-ISSN 1795-4843, no 2, p. 257-277Article in journal (Refereed)
    Abstract [en]

    This article investigates changes in visual art education through gendered visual, pedagogical and theoretical interventions. The research material is derived from a combination of two independent research projects and examples from published research. The material consists of images and video diary recordings by young people, and researched didactic examples of working with gender in visual art education. Young people’s gendered cultures include a growing vocabulary of gender definitions and ways to ‘perform’ gender. At the same time, everyday life experiences are largely structured around binary gender logics. This article answers questions regarding the ability of visual art education to change and transform stereotyped thinking and the binary oppositions of gender. Analysing visual and verbal material from a post-humanist perspective, the findings suggest that visual art education should engage with the gender problem, and that it has the capability to dissolve gender binaries and stereotypical thinking by facilitating fabulation, imagining, speculation and fantasising about the future. Visual art education seems to benefit from focusing on learning processes that are open-ended and acknowledging the affect and visual desires involved in image making. These are driving forces specific to visual art, which have the potential to differentiate gendered stereotypes.

    Processorienterad kultur: Mätmetod över beteenden som driver resultat i en processorienterad kultur2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The authors of this thesis got the idea to this projekt from a lecture and from Drucker´s quote “Culture eats strategy for breakfast”. The purpose was to investigate what behaviours that drives results in a process oriented culture, and to develop a model for measuring these behaviours.

     

    The goal was to measure the behaviours in the organisation and to help them obtain a culture that exceed the culture of their competitors, and reaching process orientation using a quantitative survey in a pilot study. Even though we got answers from all participants in the survey, the population was too small to generate statistically significant results. The study is based on the theory of four clusters; “fumblers”, “talkers”, “organisers”, and “mappers” by Eriksson and Hellström (2013) and the results are displayed in diagrams and an IPA-matrix.

     

    The conclusion is that the organisation leans towards function orientation, but they are striving towards becoming process orientated. The total picture the authors got is they belong to the cluster “talkers” with a slight margin. They are heading in the direction of becoming process orientated by focusing on their communication though. The model was designed using research about what behaviours have a positive or a negative effect on the processorientated culture of the organisation. The weakness of the model is that it only takes the cornerstone “working with processes” into account and does not measure the other perspectives of quality culture.

    Hur påverkar ledares beteende medarbetares arbetstillfredsställelse och arbetsmotivation?2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The employee's job satisfaction has received increasing attention from both researchers and employers. The majority of nowadays organizations executing continuously various surveys to find out how satisfied employees are with their tasks, work environment and development opportunities. Although that there are not many research studies that specifically show how leadership behaviours can affect employees job satisfaction, there is many studies that indicates there is a correlation between them.

     

    The purpose of this study is, to contribute to a better understanding of how different leadership behaviours can affect employee’s satisfaction and work motivation at the work. The quantitative research method has been applied, to address the relation between these subjects. Furthermore, the study has been carried out using a selection method known as snowball selection. The selection method has been an effective method for achieving many participants, which is an important parameter for statistical analysis. Total 306 employees from different companies with different work roles participated in the survey. However, the result of the study is based on 301 employees, since five of the participants were excluded during the analysis due to a lack of answers in the survey.

    The result of this study shows that leadership behaviours which concern employee participation, positive communication, employee development, social responsibility and empathy covary with employees work satisfaction and motivation. This means leadership behaviours have a significant impact on employees job satisfaction, which in turn impact employee work motivation.

    Abstract [en]

    A well functioning collaboration between actors in society is expected by the citizens. One example is a caraccident where ambulance, firebrigade and police cooperate. For particularly vulnerable groups in society with many actors, the interaction between the actors is not obvious even if the citizens receive help and support efforts. This study charts the interaction between current actors through questionnaire responses and semi-structured interviews, based on the dimensions of collaboration, participation and the customer in the center. Triangulation of data was performed to identify factors associated with the complexity of coordinating and communicating services to meet the needs of citizens. The result shows that communication and networking with clear assignments and controls can give a consensus on the citizen, his needs and quality of life, which proves to be success factors for a functioning collaboration. But since there are many players, it is complex to get an overall picture and find forms for how communication and collaboration work best.

    Abstract [en]

    The main aim of this study was to analyze the relationship between gold price and the swedish stock market. Since gold has a major role in financial systems, the interest arose because of the lack of research on the gold price relationship to the stock market in Sweden. That as well as divided view of if gold price relationship is negative, positive or not related to the stock market, has created the interest. The underlying aim of the study was to analyze therelationship between interest rate, economic growth and exchange rate with the dependent variable stock market.This study was limited by analyzing quarterly data in 23 years between 1995 and 2018 on the swedish market. Data was collected and analyzed in statistical programs named Apple Numbers and SPSS. Data was analyzed in a correlation analysis and a regression analysis. The result showed that there is a negative relation between gold price and stock market. The result also shows that there is a negative relation between between interest rate and stock market. It also shows that there is a positive relation between economic growth and stockmarket. Lastly the result shows that there is no significant relation between exchange rate and stock market.

    Should I stay or should I go? - Lojalitet och customer engagement i den digitaliserade försäkringsbranschen2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Insurances and insurance companies are of great importance to modern society when it comes to safety and development, for both individuals and companies. Despite this, the insurance industry has received a relatively small amount of attention in research, not only within business economics. Furthermore, in a time of digitalization, insurance companies are facingmajor challenges including those related to loyalty. The purpose of this study is therefore to acquire an understanding of how digitalization affects loyalty within the insurance industry, whether customers are loyal to their insurance companies, and from a customer perspective define possible influences for loyalty in a time of digitalization. Connections are made between loyalty and the concept of customer engagement to analyze the relationship betweenthe two among insurance customers. The study is conducted through ten qualitative interviews with Swedish insurance customers, aged 23 to 79 years old. The results show that insurance customers prefer human contact over digital contact in order to feel both trust and loyalty. Seven antecedents for loyalty have been identified: service and customer treatment, content and conditions, experiences, price, convenience, personal contacts, and bonusprograms. The conclusions are that digitalization has a negative impact on loyalty, and that the level of loyalty as well as the presence of customer engagement is low in the insurance industry and seems to be affected by similar factors. Therefore, the study suggests a connection between the two. The findings confirm previous research in three distinct areas: digitalization, loyalty and customer engagement, but also contributes to new insights bycombining and applying the concepts to a new field, the insurance industry. Finally, the study identifies activities that might be helpful for Swedish insurance companies in increasing both customer loyalty and customer engagement.

    Context-Based Authentication and Lightweight Group Key Establishment Protocol for IoT Devices2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The concept of the Internet of Things is driven by advancements of the Internet with the interconnection of heterogeneous smart objects using different networking and communication technologies. With the rapidly increasing

    number of interconnected devices present in the life of a person, providing authentication and secure communication between them is considered a key challenge. The integration of Wireless Sensor Networks in the Internet of Things creates new obstacles due to the necessity of finding a balance between the resources utilization and the applied security solutions. In multicast group communications, the energy consumption, bandwidth and processing overhead at the nodes are minimized in comparison to a point-to-point communication system. To securely transmit a message in order to maintain confidentiality of the data and the user’s privacy, usually involves human interaction or the pre-agreement upon some key, the latter unknown to an external attacker. In this thesis, the author proposed an authentication

    protocol based on the similar context between the correct devices and lightweight computationally secure group-key establishment, avoiding any kind of human involvement. The goal is achieved by having the devices calculate a fingerprint from their ambient context and through a fuzzy commitment scheme generating a commitment respectively opening value which is used to generate a common secret key between them. The tests are effected on real world data accumulated from different environments. The proposed scheme is based on elliptic curve cryptography and cryptographic one-way accumulators. Its feasibility is analyzed by implementing the group key establishment phase in the Contiki operating system and by simulating it with the Cooja simulator. Furthermore, the applicability of

    the protocol is analyzed and justified by an analysis of the storage overhead, communication overhead, and energy consumption. The simulator shows an energy consumption of only 112 mJ per node for group key establishment.

    The results obtained in this thesis demonstrate the feasibility of the scheme, it’s computational, and communication costs are further comparable to other similar approaches.

    Säkerhets- och kostnadsjämförelse för maskinskydd kring balningslinje: En jämförelse av förreglingsbrytare2019Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Many work-related accidents occur because safety around the LOTO principle is substandard and that the moving parts of machines are easy to access. When designing a machine, it is important to consider the machine's dangerous origin. To design this, it is important to identify and build these areas already at a design stage with, for example, a fence around machines. Access places must be carefully monitored for safe machine use according to the Machinery Directive 2006/42 / EC. In this report, safety as well as costs have been considered to an existing guard lock on access places for a baling line and examined whether costs can be reduced with the proposed PROFInet based guard lock. The harmonized standard EN ISO 13849-1: 2016 addresses one way of evaluating the safety of a machine's control system, all being evaluated according to the concept of PL, Performance Level. To calculate PL when comparing safety, SiSteMa was used and to calculate the cost of their different alternatives, an interview on costs has been made and presented as a quota. Safety comparison shows that PLd is retained. The cost comparison shows that the proposed solution is more expensive than the existing solution, but that a substandard price estimate may be behind this. One aspect of the new guard lock that was not seen in the report but worth mentioning in the conclusion about safety and cost comparison is that the proposed guard lock with PROFInet is a flexible solution with simple troubleshooting. Future work on safety at baling line would have been to look at remaining access places that are monitored by light curtains and see if costs can be reduced there.

    Judiska äktenskapsmönster 1895-1912: Stockholms mosaiska (judiska) församling2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this essay is to analyze, through a social-historical / quantitative approach, Jewish marriage patterns andits changes in the Stockholm Mosaic Assembly during the years 1895-1912. The hypothesis of this essay was that themixed marriages and the number of marriages entered have increased throughout the whole investigation period, whileit is also expected that the Eastern Jewish group has married endogenously to a much greater extent, which has meantthat the Jewish group has not been threatened by a total assimilation. The results of this essay has shown that there hasbeen a clear increase in the number of mixed marriages, especially during the years 1907 to 1912 and especially when itcomes to the Jews of western roots and mainly the Swedish inhabitants. This indicates a clear assimilation among theWestern jews. While the Eastern Jews (Russian born among others) in the higher part married within their ethnic andreligious group. New knowledge that this paper has come up with is that it was not at all unusual during the entireinvestigation period that Jewish women married Christian men, especially during the second period from 1902 to 1908,of thirty entered marriages it was the man who was the Christian part in all of the cases. This reflects the Jewishwoman's group's integration and assimilation into society. Except for this new foundings, the study is well in keepingwith the previous research on Jewish marriage patterns in the city of Sundsvall, and the jewish historical research as awhole.

    Abstract [sv]

    Markbyggarna AB är ett företag som huvudsakligen utför markarbete och maskintjänster. Företagets IT-system är formad för att stödja typiskt kontorsarbete. Projektet inriktades på att hjälpa företaget effektivisera det befintliga systemet och i större omfattning nyttja kostnadsfria alternativ som finns tillgängliga i dagens läge. Arbetet startade med definiering utav systemets avgörande aspekter. För hårdvarorna ställdes krav på CPUs, RAMs och hårddiskens belastning. För mjukvaror definierades funktioner som systemet bör innehava. För trådburen och trådlös nätverk definierades krav på internetanslutning. Efteråt samlades informationen om prestanda i det befintliga systemet med hjälpa av olika övervakningssystem, verktyg och intervjuer. PGRG tillämpades för hårdvarornas övervakning. För nätverksövervakning skapades ett eget övervakningssystem med stöd av de kommandobaserade verktygen Iperf, Speedtest-cli och verktyget Vistumbler. Övervakningsresultaten jämfördes med de önskade egenskaperna och skillnaden mellan dessa två utgjorde underlag för förändringsarbete även med beställarens önskemål i åtanke. Såldes gick den praktiska delen av projektet bland annat på att trådlös signal förstärktes genom installation av AP, introduktion av nya applikationer, en anslutning till företagets PC hemifrån samt skapades system för säkerhetskopiering. Även har en rad andra säkerhetsåtgärder vidtagits. För att kunna utvärdera det genomförda arbetet övervakades det trådlösa nätverket på nytt. Dessa förändringar har gjort att IT-systemet blivit säkrare, med bättre presterande nätverk. Flexibiliteten och funktionaliteten har också ökat. Totalt gick projektet på 1660 kr för inköp av hårda varor. Det gick att täcka de flesta av företagets behov med kostnadsfria mjuka varor.

    Lifetime abuse and somatic symtoms among older women and men in Europe2019In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 14, no 8, article id e0220741Article in journal (Refereed)
    Abstract [en]

    Background

    Research suggests that survivors of interpersonal violence have an increasing experience of bodily symptoms. This study aims to scrutinise the association between lifetime abuse and somatic symptoms among older women and men, considering demographics/socio-economic, social support and health variables.

    Methods

    A sample of 4,467 community-dwelling persons aged 60–84 years (57.3% women) living in seven European countries (Germany, Greece, Italy, Lithuania, Portugal, Spain, Sweden) was recruited for this cross-sectional study. Lifetime abuse (psychological, physical, sexual, financial and injury) was assessed on the basis of the UK study of elder abuse and the Conflict Tactics Scale-2, while somatic symptoms were assessed by the Giessen Complaint List short version.

    Results

    Women reported somatic symptoms more frequently than men. Multiple regression analyses revealed that lifetime exposure to psychological abuse was associated with higher levels of somatic symptoms among both women and men, while experiencing lifetime sexual abuse was associated with somatic symptoms only among older women, after adjusting for other demographic and socio-economic variables. Country of residence, older age, and low socio-economic status were other independent factors contributing to a higher level of somatic symptoms.

    Conclusions

    The positive association between the experience of abuse during lifetime and the reporting of higher levels of somatic symptoms, in particular among older women, seems to suggest that such complaints in later life might also be related to the experience of mistreatment and not only to ageing and related diseases. Violence prevention throughout lifetime could help to prevent somatic symptoms in later life.

    Identifying Traces of Boundary Object Properties in Data Hub Development Narratives: Two Cases from Scandinavian Electricity Market2019In: AMCIS 2019 Proceedings, 2019Conference paper (Refereed)
    Abstract [en]

    Digital technology enables multi-relational collaborations between parties with different experiences, knowledge, values, and goals. Regarding digital technology triggering enterprise transformation, boundary object as theoretical model for understanding such differences in development is not well understood, especially the ways boundary object emerges in practice. We inquired what traces of boundary object properties can be identified in data hub development narratives. An interpretive approach was chosen for understanding experience-centered narratives that origins from interviews conducted in two separate studies of national development of data hubs for the electricity market in Denmark and Sweden respectively. Through a literature review covering boundary objects, nine prosperities were chosen for the theoretical frame used in the interpretation of the narratives. The conclusion was that boundary object properties were part of the narratives of the data hub developments early on in the in-use taking processes and even before the digital artifact was taken into use.

    Integrerad dokumentation: Operatör- och servicemanual inbyggd i HMI2019Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Valmet has received requests from customers to integrate manuals as part of the automation system. This report shows a concept of how that problem could be solved by incorporating manuals with functions and that the texts are available for reading. The goal is to be able to extract more information from HMI by integrating the operator and service manuals in the automation system. The method for this work was to start with a literature study on the topics: alarm, HMI and document integration. After a literature study, a development phase began that used the knowledge from the literature study to build the products. The final phase of the work was to test the functionality and evaluate the result. The result was a new alarm view with enhanced functionality, such as, for example, displaying additional information at clicks, an automatic maintenance system with low performance impact and PDF of the manuals available in HMI. The goals of the work are considered fulfilled since additional alarm information is available, a maintenance system is implemented, and the manual can be read in HMI. Future work could be to make the alarm view more robust by detecting and correcting errors, further integrating the contents of the manuals, possibly how to run the machine.

    Swedish mothers' and fathers' worries about climate change: a gendered story2019In: Journal of Risk Research, ISSN 1366-9877, E-ISSN 1466-4461Article in journal (Refereed)
    Abstract [en]

    The present study considers whether parenthood has an impact on the worries that women and men have about climate change for the next generation and examines whether there are differences between the worries of mothers and fathers. The empirical material is based on a questionnaire-based survey that was administered in 2011 to a random selection of 3500 individuals in Sweden, with a response rate of 31%. The results indicate that parenthood, regardless of the parent’s gender, increases an individual’s worries about the impact of climate change on the next generation. Fathers are significantly more worried about climate change than men who are not parents; however, mothers do not worry significantly more than women who are not parents. In general, regardless of parenthood status, women worry about climate change more than men.
