    On the influence of imperfections on microstructure and properties of recycled Al-Si casting alloys2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    There are great energy savings to be made by recycling aluminium; as little as 5% of the energy needed for primary aluminium production may be required. Striving to produce high quality aluminium castings requires knowledge of microstructural imperfections, which is extra important when casting recycled aluminium that generally contains higher levels of imperfections compared to primary aluminium. Imperfections include amongst others Si, Fe, and Mn as well as oxides. Si is needed for castability, but it may also initiate fracture. There are different types of Fe-rich intermetallics influencing properties of castings, generally in a negative direction. Oxides constitute cracks and they are elusive because they are difficult to quantify.

    This thesis aims to increase knowledge about imperfections in recycled aluminium castings originating from alloying elements and the melt. Experiments were performed in advanced laboratory equipment, including X-radiographic imaging during solidification and in-situ tensile testing in a scanning electron microscope. Experiments were also performed at industrial foundry facilities.

    The experiments showed that the nucleation temperature of primary α-Fe intermetallics increased with higher Fe, Mn, and Cr contents. Primary α-Fe are strongly suggested to nucleate on oxides and to grow in four basic morphologies. Lower nucleation frequency of α-Fe promoted faster growth and hopper crystals while higher nucleation frequency promoted slower growth rates and massive crystals. Results also showed that a decrease in the size of the eutectic Si and plate-like β-Fe intermetallics improved tensile properties, foremost the elongation to fracture. In β-Fe containing alloys the transversely oriented intermetallics initiated macrocracks that are potential fracture initiation sites. In alloys with primary α-Fe foremost clusters of intermetallics promoted macrocracks. In fatigue testing, a transition from β-Fe to α-Fe shifted the initiation sites from oxides and pores to the α-Fe, resulting in a decrease of fatigue strength. Oxides in Al-Si alloys continue to be elusive; no correlations between efforts to quantify the oxides and tensile properties could be observed.

    The influence of thermal expansion of unbonded foundry sands on the deformation of resin bonded cores2017In: Archives of Metallurgy and Materials, ISSN 1733-3490, E-ISSN 2300-1909, Vol. 62, no 2, 795-798 p.Article in journal (Refereed)
    Abstract [en]

    Depending on the preparation and the applied materials, moulds and cores can be of high rigidity or can be flexible. Although, chemically bonded moulding materials have relatively good flexibility, their high temperature behaviour determines the dimensional accuracy, the stresses in the castings and can induce several casting defects, such as rattail, veining, etc. The phenomenon is based on two major effects: the thermal expansion of the unbonded foundry sands and the deformation of the sand mixtures. The main objective of the present work was to study the relationship between these two effects, and to improve the knowledge related to the thermo-mechanical interactions between the casting and the mould. Dilatometric analysis of unbonded sand samples were performed and compared to the results of hot distortion tests of moulding mixture specimens. The results showed, that the thermal expansion of foundry sand largely influences the hot distortion behaviour, but depending on the type of binder used.

    Utomhusmiljöns möjligheter att utveckla barns lärande: En kvalitativ studie ur ett verksamhetsteoretiskt perspektiv2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med studien var att uppmärksamma hur utomhusmiljön kan bidra till lärande utifrån den fria leken och med hänsyn taget till verksamhetens pedagogiska organisering. Utifrån syftet i studien uppkom dessa frågeställningar. Vilka möjligheter och hinder existerar i arbetet med att utveckla barns kunskaper och lärande utifrån den fria leken och av att organisera den planerade verksamheten som är relaterad till utomhusmiljön? Vad utmärker pedagogiskt planerade aktiviteter relaterade till utomhusmiljön och i förhållande till verksamheten som helhet? Den teoretiska utgångspunkten i studien är ett verksamhetsteoretiskt perspektiv. Centrala begrepp som har används inom teorin är Wartofskys syn av artefakter, motsättningar och expansivt lärande. För att undersöka våra frågeställningargenomfördes kvalitativa intervjuer med sju pedagoger på fem olika förskolor. Observationer har även genomförts som ett komplement till intervjuerna på samtliga förskolor i studien. Resultat i studien synliggör att pedagogerna anser att i den fria leken finns det möjligheter att utveckla barns lärande. De förutsättningar och tillgångar som pedagogerna ges påverkar vilka möjligheter till lärande som pedagogerna kan erbjuda barnen. Det framkommer även att de förutsättningar barnen ges till pedagogiskt planerade aktiviteter skiljer sig mellan verksamheternas utomhusmiljöer och inomhusmiljöer.

    Skolans värdegrund – i teori och praktik: En kvalitativ intervjustudie om verksamma lärares tolkningar och appliceringar av skolans värdegrund2017Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The Swedish schools’ “värdegrund”, or as it would be called in English, the Swedish schools’ fundamental values, are something that’s been granted the first chapter in the national curriculum. It’s something quite unique and not something you’ll find in other nations’ curriculums.1 The questions this study has been asking is not why it exists but rather how teachers interpret it and how they work in relation to these values. Another question that’s been raised concerns how teachers relate to the fosterage role that is assigned to them according to the curriculum.

    To answer these questions a qualitative interview study has been conducted where six upper secondary school teachers were interviewed. The interviews where analyzed thematically and then further analyzed and discussed in relation to different theoretical perspectives.2

    The study found that even though these teachers were somewhat vague in their interpretation of the fundamental values they still showed an awareness about the central principles of it and how to work accordingly. The study also showed that there were two ways the teachers worked according to the fundamental values, in this study these were named: “the conflict solving fundamental values” and “the knowledge mediating fundamental values”. The study also found that the teachers’ relations to their fosterage role is quite strong and that it’s something they try to act according to.

    Att planera och skriva olika typer av texter: - En kvalitativ textgranskning av elevboken Zick Zack Skrivrummet årskurs 42017Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The Swedish state does not longer decide the selection of teaching materials used at schools. Today, the teachers select by themselves which teaching material that should be used in Swedish schools. Which means that the content in the textbooks doesn’t need to be adapted for a particular syllabus. The aim of this study is to review the content in a textbook, called Zick Zack Skrivrummet, based on the intentions the authors have and discuss the outcome in relation to the theory of genrepedagogy. This study is based on a qualitative method with quantitative elements with a hermeneutic interpretation. The socio-cultural theory as well as genre pedagogy has been used in this study to understand the result. Zick Zack Skrivrummet is based on genre pedagogy and “the curriculum circle” and is adapted to the Swedish syllabus. The study shows that the textbook is adapted to Lgr11 and contains all six different texttypes. Working with “the curriculum circle” in the textbook, the students is getting better at planning and writing different texttypes. The study also shows that the content in the textbook is still the same and have not been updated since it first was relesead in 2011.

    Design Platform: A Coherent Model for Management and Use of Mixed Design Assets2017In: Transdisciplinary Engineering: A Paradigm Shift: Proceedings of the 24th ISPE Inc. International Conference on Transdisciplinary Engineering / [ed] Chen, C.-H., Trappey, A.C., Peruzzini, M., Stjepandić, J., Wognum, N., IOS Press, 2017, no 3-4, 703-712 p.Conference paper (Refereed)
    Abstract [en]

    For many companies, it is a challenge to balance product variety and cost, i.e. external and internal efficiency. Product platforms has been the dominant solution for a business targeting mass-customization. The main idea is to dived the product into modules that can be shared among different product variants. This has been a success on the consumer market, however, many manufacturing companies are engineer-to-order (ETO) oriented, such as original equipment suppliers (OES). They design a unique solution, often in close collaboration with other companies, based on different product concepts and/or core technologies. For these companies, there is a strategic need for a platform model influenced by the principles of masscustomization, although, not limited to only include modules. In this work, a novel platform model, called Design Platform is described. The model has been developed and applied in cooperation with four companies. The Design Platform provides a coherent environment for management of heterogeneous design assets to be used in product development and supports an improved ability to master fluctuating requirements and systematic introduction of new technologies.

    Samer i svenska dagstidningar: En innehållsanalys av nyhetsrapporteringen om Europas enda urfolk2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This paper examines the Sami peoples representation in Swedish newspapers. Previous research show that news media holds a growing power in affecting how different groups are perceived and being treated in today’s society. It shows how indigenous people and minorities are limited in the news media and portrayed in a homogeneous and biased way. This study examines to which extent the Sami population is being seen in the Swedish news media, what kind of Sami related news that are being reported and, how the Sami people are being presented. The method used to answer the thesis questions is a content analysis with complementary qualitative and quantitative elements. Articles published in three Swedish newspapers during the period of one year have in this study been examined. The result indicates that Sami culture is given a lot of space in the reported news, while other important events and questions concerning the Sami people are less visible. The result is analyzed on the basis of postcolonial theory, and connection could thus be distinguished between Sweden's historical relationship with the Sami population and the media's presentation of the group.

    Kommunikationsmodell för APD-plan vid användning av materialrutor och gångstråk2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: On-site construction is a complicated process. A temporary factory, with new zones for materials and workplace area must be established for each new project, which complicates the process further. Material management stands for a big saving opportunity in building projects and 40 % of the time lost on a construction site can be attributed to material management.  To overcome this waste connected to material management a well-processed logistics planning, god communication as well as experience feedback from previous projects is required. The aim for this thesis is therefore to identify improvement measure regarding the use of material-dedicated buffer zones and walking paths, and as well as create a model of communication that supports experience feedback.

    Method The thesis is a case study on two projects within the organization of NCC.  A qualitative data collection with literature review, interviews, document analysis and observation has been conducted. Semi-structured interviews have been conducted and includes seven respondents with different position within the construction industry.

    Findings: The thesis has produced factors that should be taken into consideration when material zones and walking paths are planned. The result shows that resources and structured processes are required if experience feedback should work during the construction project. To succeed with the use of material-dedicated buffer zones and walking paths, good communication of the construction site plan is needed. Furthermore, the thesis has resulted in a model of communication that supports experience feedback.  

    Implications: It’s during the purchase and delivery planning that the conditions for the material-dedicated buffer zones and walking paths are set, therefore the construction site planning should be involved more in this phase. A prerequisite for using dedicated material zones and walking paths are resources which supports the construction management with planning and performance. By using logistic resources within the organization facilitates planning and management of material at the construction site, enables that collected experience can be conveyed between projects. In the production there should be a responsible receiver of material deliveries, who is extra briefed in the constructions site plan and the material-dedicated buffer zones through continuous communication with the construction management and logistic resource.

    Limitations: Since the thesis only includes two building projects, there is a limitation of the factors and arguments that are treated. Although the result is based on two building projects the fundamental processes and course of events are similar and can therefore be applied on other building projects.

    Kalkylskedets möjlighet till påverkan vid miljöcertifiering enligt Miljöbyggnad2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: Environmental impact by humans has increased significantly, with the construction industry accounting for 40% of the world's energy consumption. In order to counteract this, the world's demands on sustainable buildings have increased. There are a number of environmental certification systems to help, where Miljöbyggnad is the most common in Sweden. The possibilities for influencing a project are greatest in the early stages, which also applies for environmental work. Therefore, the objective of this study is to investigate how a project classified according to the Miljöbyggnad Silver affects the bidding process for a construction project, in comparison with a similar project without environmental certification requirements.

    Method: A literature study which aims to form a theoretical framework, a document analysis of a reference project based on provided documents and semistructured interviews with calculation engineers at Serneke Bygg AB in Gothenburg.

    Findings: The results of the document analysis and interviews contradict each other to some extent. The document analysis shows several aspects that can be influenced by the calculators' work, while the respondents mention only a few differences between a project with or without certification according to Miljöbyggnad Silver. Respondents consider themselves lacking knowledge about environmental construction, while at the same time they are uncertain of how much that is needed. The document analysis, on the other hand, indicates that additional knowledge is required to ensure that the above mentioned aspects are taken into account in the calculation phase in order to ensure that the bid meets the requirements for Miljöbyggnad Silver.

    Implications: In order to ensure that the environmental building requirements are met in the tender phase, the recommendation is that the calculators, or one employee, will acquire knowledge about Miljöbyggnad. However it depends on the company's ambition regarding the accuracy of the tender if this will be implemented. Their attitude will have significance to how the work process and time aspect will be affected with the increased requirements of knowledge.

    Limitations: Only one type of environmental certification and one individual project have been selected. The study's goals are considered to be met, but the results and conclusions could have been further strengthened if more projects were studied and interviews had been conducted with the head of the department.

    SABIC Green Logistics Systems & Profitability: To explore chemical industries green logistics and contribution to profitability with a particular case of SABIC2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background: Logistics is paramount in the business operations as it ensures transit of goods from one point to the other. Green logistics are measures in the logistics systems that are put in place to minimize the environmental implication of logistics operations while at the same time saving on cost. Thus, green logistics is adopted as it conveys a competitive merit which enhances performance of a company. Saudi Basic Industries (SABIC) is one of the biggest petrochemicals in Saudi Arabia and holds the fifth position in the world among the leading producers of petrochemicals. The company already has green logistics in place.

    Purpose: To explore chemical industries green logistics practices and profitability with a particular case study of SABIC. The goal of this paper was achieved by investigating how has SABIC incorporated green practices into supply chain operations to remain profitable. The study answers “how has chemical industries incorporated green practices into supply chain operations to stay profitable?’ And “how do logistic managers recognize green logistics and to what level do chemical industries apply green logistics? Investigating a chemical industry green logistics is important as it contributes to literature since no single study has been carried out in this area. Suggestions from this study are crucial to SABIC, other chemical industry besides any other industry since in one way or the other companies do logistics.

    Method: The study utilized interpretivism. This study was a case study type of thesis focusing merely on SABIC, and it employed induction approach as well as the qualitative method of collecting data.  Interviews were used to explore the experiences, beliefs, motivations and views of individual participants. Using non-probability sampling method, five members in SABIC supply chain department were selected.

    Conclusion: The results show that SABIC or chemical industries utilize most of the green logistics activities (fuel efficiency, route optimization package optimization and calculating carbon emission). However, it was found out that fuel efficiency, route optimizations, and packaging optimization were most common activities. It was also discovered that one major objective of chemical industries going green was to cut cost which contributes positively to its profitability. However, reverse logistics was not familiar because of its nature; it cannot be sufficient on its own.

    Kommunikationsproblem mellan arkitekter och konstruktörer vid projektering av flervåningshus av trä- och betongstomme2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The purpose of the study is to identify communication problems in the planning process between the architect and the structural engineers in building framework of wood and concrete structures in multi-storey buildnings and investigate the causes of these problems. Wooden frames in multi-storey buildings is on rising and challenges the dominant concrete frames. Difficulties in cooperation between disciplines can not be underresimated, especially in complex projects. Communication is a complex process and the key to project performace.

    Method: The study consists of a qualitative approach. The used methods are interviews and literature studies. The interview method is based on people's experiences and opinions. The interviewed respondents are architects and structural engineers, all of whom have worked in planning process of both concrete and wooden frames. Literature studies have contributed to a deeper understanding of the subject as well as information about the current research front.

    Findings: Misunderstandings in written communication and undocumented conversations are communication problems that most of the architects and structural engineers experienced. Communication problems are caused by lack of time and stress. Collaboration between the various disciplines can be adversely affected when there is no understanding of the other parties. The communication problems that have been experienced in the planning process are general and usually not affected by the choice of frame. Lack of knowledge, on the other hand, has been perceived as an additional communication problem regarding the planning process of wooden multi-storey buildings. Experience is a reason for this. Differences in communication are not affected by the choice of frame, however the communication frequency has increased.

    Implications: To achieve effective communication in the planning process meetings with protocol are to prefer. The lack of knowledge in the construction of high-rise buildings in wooden frames are based on the difficulty of finding experience. An increased communication frequency has been a fact because the innovation of wood frames. Future recommendations are to investigate and propose solutions to the communication problems and implement solutions to the industry.

    Limitations: The results of the study are limited to the architects and the structural engineers perspectives although the planning process in fact involves more parties. Collected data is based on the respondents personal opinions and experiences, therefore the results can not be determined as a general perception for all those with the same profession.

    Keywords: Architect, constructor, communication, planning process, wooden frame, concrete frame, communication problem, multi-storey house.

    Purpose: Environmental certifications strengthens a contractors environmental profileand means sustainability in regards to the environment. It is of interest to establishwhich obstacles and differences in workflow that environmental certifications cancause and thereby imply challenges in construction. The purpose with this paper is toexamine what impact the environmental certification Miljöbyggnad Silver has on acontractors work in the construction stage with focus on structure and frameworksupplement.

    Method: To reach the purpose of this paper empirical data have been collected throughinterviews, private documents, and observations of building construction. This researchemploys a qualitative method to get a comprehensive understanding of Miljöbyggnadin construction, where respondents with different occupations and extents of experiencewith Miljöbyggnad have been chosen for interviews.

    Findings: This research shows that the indicators in Miljöbyggnad that mainly have animpact on construction is Moisture safety, Documentation of building material andPhasing-out of harmful substances. The research shows that the biggest differencebetween conventional construction and construction with Miljöbyggnad is the amountof documentation that is needed. Construction with Miljöbyggnad also differsdepending on what occupation one has.

    Implications: The conclusion of this research is that there are no great obstacles withMiljöbyggnad Silver in construction. Indicators from Miljöbyggnad impactsconstruction with additional obligations for site management and does not implicate adifference in already established ones. Recommendations following this research is toinvolve and encourage Miljöbyggnad for everyone involved in construction.

    Limitations: This research is limited to big contractors and the environmentalcertification Miljöbyggnad Silver where focus have been structure and frameworksupplement. Through analyses of indicators and interviews the authors have concludedthat it is structure and framework supplement where impact following Miljöbyggnadexists. The result of this research and its conclusions are considered to apply with othercontractors with similar routines and work flow.

    “You have to have a certain feeling for this work”: Exploring tacit knowledge in elder care2014In: SAGE Open, ISSN 2158-2440, E-ISSN 2158-2440, Vol. 4, no 2Article in journal (Refereed)
    Abstract [en]

    Increased care worker knowledge has been emphasized for improving quality of care for older persons in organized elder care in Sweden. However, care workers and national policies are not always corresponding, with observations suggesting that care workers emphasize tacit knowledge. The aim of this article is to explore the nature of this kind of knowledge and how it can be identified and described. Field notes from participant observations at two elder care units in Sweden serve as the empirical material. Knowledge use for staff in elder care is part of a process of knowledge making and knowledge shaping. Analysis of the field notes identified the themes of “feeling for work” and “acting and artistry” as parts of a tacit knowledge in elder care. The processes of knowledge and job execution are closely intertwined, making them difficult to separate or even understand without a deeper insight.

    The best place to hide a dead body is page 2 on Google search results2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose - This examination paper examines what affects which link students at Jönköping University choose to click on the Google search results when they do a product search. For some e-commerce companies, it may be crucial that users click on their link in the search results. But which link do students choose to click on? Are they choosing to click on a link in the organic search results or are they choosing to click on an ad? This examination has been carried out with the aim to help e-commerce companies that sells products that target students. During this paper has following question has been answered:

    • What affects the link Jönköping University students choose to click on the Google search results?

    Method - To answer the question three different methods has been implemented to collect data. The methods conducted three interviews with experts in the SEO industry, 114 observations with students and in connection with the observations did the students answer a digital survey. These three methods gave a good and comparable results that ultimately strengthen each other.

    Results - Based on data collected from interviews, observations, digital surveys and secondary data have a result been developed shrill guessed what affects students' choice of the links on the search engine Google. The result shows that search engine optimization is important for an e- commerce business that must appear on Google, if you are not on the front page you are not existing. Although the recognition factor plays the most important role in the choice of which link students click. Where it appears two different kinds of behaviour both with the recognition factor of ulterior motive. Either the students click on the first link they recognize or choose them consciously remove the ads and click on the first common link them recognize.

    Implications - This work is only carried out on students from Jönköping University. A representative selection was made from the theoretical population of a generalizable results. But to generalize the results of the students to a greater extent it is required that the same survey conducted at various colleges / universities in Sweden.

    Limitations - Focus and most time was spent on implementing the observations which gave less time to conduct more than three interviews. This is a crucial factor that affected the study's scope and results. If there were more time had an investigation on other search engines would have been feasible. All searches were made on Google, which is the largest and the leading search engine in the world. If they are doing any big changes or updates our results may be unusable.

    Detektion av fasta ekon vid vindmätning med SODAR2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose – The purpose of this thesis was to facilitate the search for echoes caused by fixed objects, so called fixed echoes, when using SODAR-technique for wind measurements. Furthermore, it was investigated how fixed echoes in measurements can change based on different conditions such as: the angle of the sound beam towards the object causing the echo, the output frequency of the instrument, the air temperature and relative humidity.

    Method – Data was recorded on a test site in southern Sweden during February - April 2017 using two different SODAR-instruments, AQ500 and AQ510, manufactured by AQSystem. Experiments were conducted by installing the instruments at different distances and in different angles next to a met mast. The data recorded was examined for fixed echoes both by using Excel and manually and compared for correlation with the parameters mentioned. A software that uses the r-squared value for a power function adapted to the collected data was developed to detect fixed echoes.

    Findings – The result of the study showed that the angle of the SODAR-instrument sound beam direction compared to the met mast has a relatively high impact on the number of fixed echoes that can be easily detected. When a sound beam is aimed directly at the fixed object the echoes increased significantly compared to when the sound beams were aimed next to the mast. AQ510, that uses a higher measurement frequency than the AQ500, was less susceptible to fixed echoes when doing simultaneous measurements. Both temperature and relative humidity showed low correlation to the number of fixed echoes so the implication was that these atmospherical parameters do not affect the emergence of fixed echoes. The r-squared value for a power function adapted to the wind data turned out to be a good measure for the magnitude of a fixed echo. When the correlation coefficient of the r-squared value and the percentage of wind profiles that contained fixed echoes were calculated the value was 0,995 which is a strong positive correlation. The r-squared value is compared with a threshold value (which depends on the number of wind profiles in the data to be analysed) to determine if a fixed echo is causing disturbance. Another control is also made in the software where the measured wind values are compared with the values from the power function to find minor deviations possibly caused by fixed echoes.

    Implications – When the result of the thesis is considered it can help the person installing the instruments as well as the developers of the SODAR-instruments. The person installing the system can notice that fixed echoes can be decreased by rotating the instrument. The result showed the developer that by carefully selecting the right frequency the number of fixed echoes can be decreased. If neither the temperature nor the relative humidity has any impact on fixed echoes it shows the developer that the instrument can be used in varying climates. The result of the study can also be of service to wind analysts using SODAR-equipment. The software developed can be used to find fixed echoes in a more efficient way than was previously possible.

    Limitations – The data recordings took place during a limited period during late winter, early spring in the southern parts of Sweden which means that neither extremely high or low temperatures were measured during the campaign. The thesis is further limited by only using ”multiple axis” SODAR-instruments from AQSystem.

    Keywords – SODAR, wind measurements, fixed echoes, measurement instrument.

    Spel och moral: En studie om de moraliska omständigheterna kring TV-spelet This War of Mine1991Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A study about the moral circumstances of the video-game This war of mine. By use of earlier research it establishes a connection between video-games and our behavior. Through that and the arguments of Michel Sicart I define video-games as an ethical object. With that as a main premise, I continue to analyze This War of Mine (abbreviated as TWoM) using normative, ethical models, with the purpose of highlighting the games underlying values. The main component of the study is divided into two parts: analysis of the games twelve, playable characters and analysis of the games rules. The results establish that the games underlying, ethical values are universalistic in nature with a tone of utilitarianism through the quantitative and contextual natures of how your actions are measured.

    Abstract [en]

    Purpose: To investigate the effects of replacing major parts of facades in officebuildings with glass, focusing on the energy use and the carbon dioxide emissions

    Method: Qualitative semi- structured interviews, literature studies and documentanalysis.

    Findings: An office building was studied with regard to the specific energy use andcarbon dioxide emissions. The glass area and façade area were calculated for theexisting building. Then the glass area was expanded from 30 % to 50% and 70%respectively. The result showed that an increase from 30% to 50% decreased thespecific energy use for all four energy calculations carried out in Gothenburg, Lund,Stockholm and Umeå. On the other hand, the specific energy use for all cases increasedwhen expanding the glass area from 50% to 70%. When analyzing carbon dioxideemissions, it was found that the carbon dioxide content always reduced as a result ofthe increasing glass area.Implications: The report clearly shows that there is a problem regarding energyconsumption and carbon dioxide emissions today. Building rules and advice should befollowed by the construction industry in order to achieve the goals set by the EU. Thestudy shows that there is a clear connection between carbon dioxide emissions and theincrease in the glass area, however, this connection was lacking for the energy use.

    Limitations: The work is limited to investigating an office building with concreteframes located in Gothenburg, Stockholm, Lund and Umeå. The architecturalperspective of the glass is not considered and therefore it does not influence theselection nor does placement of the glass portions, the glass have no bearing attributes.

    Förbättringsåtgärder i dagens livscykelanalysarbete: En studie av två programvaror2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: For newly constructed buildings, embodied carbon dioxide stands for an increasing share of the buildings climate impact, seen from a life cycle perspective. This due to improved building envelopes alongside better building service systems. Research shows climate impact due to embodied carbon dioxide may decrease if digital tools for analysis are used during the design phase. The aim with this report is to examine how these analyses are made and see how they can be simplified as well as more accurate.

    Method: To fulfil the aim of this report a literature review is used alongside semistructured interviews to map the use of LCA (Life Cycle Assessment) in order to gain knowledge and find opportunities for enhancement. A case study is performed on a building frame of concrete and steel to be able to compare and draw conclusions from two LCA-tools; Anavitor and Bidcon.

    Findings: The result shows increasing interest for LCA in the building industry and that LCA performed in the design phase often uses generic values. The terms and scope of a LCA needs to be determined distinctly regarding comparison of different software's in order to reach a result that is comparable. There is a need to depart from generic values and replace with climate data from manufactures to reach a result reflecting reality. This would be possible already in the design phase using objects in BIM supplemented with climate data from EPD:s in compatible formats.

    Implications: The buildings total climate impact during the life cycle are able to be displayed with LCA-tools. Using this as a natural part of the design phase, LCA-tools have to be compatible with the information contained in an eventual model. LCA-tools ought to include more information than just climate impact, other environmental data and economic information ought to be included to provide a better decision ground for the buyer. To increase the use of LCA in the building industry, a stronger incentive is needed. The buyer should be required to perform an environmental declaration of thebuilding. In a further step legislation regarding a building´s environmental impactsimilar to the rules found in the Swedish building code regarding specific energy usewould be fitting. The accuracy of the programs mostly depends on the input data,namely quantities, often retrieved from a model. Requires EPD:s accessible in formatsupported by digital software’s in order to reach that information more easily. LCA tools ought to be used early in a project, facilitate eventual choices. At the same time, the user should be able to use product specific EPD:s in an early stage to compare different manufacturers and solutions.

    Limitations: This paper is limited to the two software’s Bidcon and Anavitor, and how they differ regarding calculation methods and functions. It's also limited to only take the buildings' embedded materials into account.

    Energieffektivisering med fukthänsyn av ytterväggar på plankhus2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: Villas built before 1960 represent around 45% of the dwelling in Sweden. Since the average U-value in their walls is around 0,5 W/m2K, there is a great concern to improve  these values. The Swedish government's goal is to reduce energy intensity in the country by 2020 by 20 % from 2008’s values. The aim of this study is to reach phase renovation proposals taking into account energy and moisture on houses consisting of standing shelves. With this, the authors wish to contribute and encourage renovation of existing villas, which in turn can lead to reduced energy consumption.

    Method: This work is based on a case study of a 1940’s wooden house located in Skillingaryd. Measurements and parameters have been taken in order to calculate the house's specific energy usage in the BV2 analysis program. Document analyses and interviews have been used to get a deeper knowledge of existing conditions, and to suggest ways to utilise the material that the market offers nowadays. This should serve the purpose of creating as energy-efficient phase resolution as possible.

    Result: The study shows that an outer wall of a massive wooden house should keep a U-value of 0,15 W/m2K to meet the specific energy consumption of 90 kWh/m2 and year, when the other house is additional insulated. The study presents two refurbishment proposals supported by interviewed experts in the insulation and consulting industry. The first option leaves large parts of the old facade untouched, adding new insulation layers of the desired thickness. The second option advises to tear away all old panels into the shelf frame, thus re-building with new materials. Both proposals address the issue of how the facade should be refurbished in order to make it moisture proof. They mostly solve the problem by refurbishing it outwards and by eventually placing a vapor barrier for a maximum of one third in of the insulation. This vapor barrier may or may not be a watershed according to the experts. Some think it is unnecessary when the plank is considered sufficiently diffusion-proof; some believe that it will help to identify where a possible condensation might occur in the wall. 

    Consequences: The study shows that by means of additional insulation, BBR 24 recommended values ​​can be achieved for an exterior wall while keeping the façade moisture proof. One strength the study shows that the two reported renovation proposals achieve the same end result, although the interference on the facade varies in size. Therefore the authors of the above study recommend to tear down the old facade and build a new control wall with a finishing facade disc. This is when you face a vapor barrier on the façade with a vapor barrier that is laid on the old baselayer of the roof. Then a new roof construction could be built up with roof beams, shavings and roof tiles. As a result, a windy, yet proportional, construction can be created.  

    Restrictions: The study assumes that the entire house would be refurbished in order for the specific energy use to be possible. Furthermore, the work is based of a shelf shelter located at a particular geographical site. Due to this, the study also offers suggestions on wooden facades only. 

    Keyword: Plank body, Phase renovation, Specific energy use, diffusion, convection, U-value, air density.

    Sustainability performance indicators at shop floor level in large manufacturing companies2017In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 61, 457-462 p.Article in journal (Refereed)
    Abstract [en]

    This article investigates sustainability in the performance measurement systems of Swedish manufacturing companies. It builds on a previous study that documents relatively few direct environmental indicators at shop floor level, which raises questions about possible indirect links between existing indicators and the environment that could be used to improve the environmental aspect of company´s sustainability ambitions. 

    A method for identifying and categorizing indirect links to sustainability issues was defined and used. The results suggest that at shop floor level 90% of the indicators have at least an indirect relation to one or more of the sustainability dimensions economy, environment and social, of which 26% are at least indirectly related to the environmental dimension. Despite the many indirect connections, participating companies perceive a need to improve sustainability indicators and some ideas are suggested.

    The Education Act: Conditions for a Research-based School A Frame-Factor Theoretical Thinking2017In: International Journal of Research and Education, ISSN 2398-3760, Vol. 2, no 2, 1-13 p.Article in journal (Refereed)
    Abstract [en]

    In 2010, the Swedish Parliament enacted a new education act that, among other aspects, stipulated education in primary and secondary schools must be based on research and proven experience. Such a legal requirement that would apply to both school levels is quite innovative not only in Sweden but internationally. Over the years principals and teachers have developed new pedagogies designed to improve teaching and learning. Could another means toward such improvements lie in a law stipulating that education in primary and secondary school must be based on research and proven experience? What conditions are required for such a law to affect the work of the school faculty and staff? The analytic methods used in this investigation are Lundgren’s frame factor theory and Goffman’s frame analysis. The focus is on the relationship between parliamentary control via legislation and the possibilities of principals and teachers to fulfil the intentions of the law. Our analysis reveals that the law experienced difficulties due to it not being properly implemented and not providing clear instructions on how it should be used in teaching practice.

    Ökad patientdelaktighet under hela vårdtillfället: -En studie av ett förbättringsarbete vid en avdelning på en geriatrisk klinik2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Jakobsberg Geriatric Clinic emphasizes the importance of value creation and working methods from a patient perspective that gives results of relevance to the patient, where participation is given as an essential part. Patient surveys have shown that there is a gap between the target and working processes, which does not promote participation sufficiently.

     

    The purpose of the improvement work was to increase patient participation throughout the hospital stay.

    The purpose of the study was to identify experiences that could be linked to the changing working methods, through a patient’s as well as an employee’s perspective. 

    The Improvement work was performed with a quality design and an interactive research approach where care-staff drafted proposals on useful methods that would better favor patient participation. These methods were then tested by repeated PDSA-wheels. 

    To answer the questions to the study, mixed method was used. Semi-structured focused group interviews were conducted and participation observations occurred. Individual interviews were held and patient’s surveys were filled out to evaluate the experience of the changing working method. 

    The improvement work resulted in a number of changes, from admission to discharge, where the patient’s own expectations, wishes and needs, became more central. Examples of changes; an increased focus on patient participation, from the enrollment, as well a reconciliation offered midway through the care episode with the purpose to catch arising issues and to identify additional needs.

     The findings in the study demonstrate the importance of clear communication / information within the team and with the patient as a partner in decision-making. Insights on team processes and activities that need to be further adapted during the care process to create better conditions for increased.

    Övergångsprocessen till ISO 9001:2015: Metoder och hjälpverktyg inför skiftet till ISO 9001:20152017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The key point in this thesis has been to illustrate the overall picture of a transitions process where the tools and methods are applicable on all companies that will make the transition to ISO9001:2015. Furthermore has the case company’s current situation been thoroughly studied with suitable methods to prove how this can be done and the importance it has to easen the transition to a new standard. The key is to ease the transition process to ISO9001:2015 (figure 1).

    1. Which methods are suited to determine the current situation regarding ISO9001?

    This has been answered by collecting data by using many different methods. The methods were then compared to each other to figure out which differences and similarities there was. The used methods are: serveys, dialogues and a self-developed method ”metod för egen bedömning” (method of self-assessment). The analysis was conducted and the results show that the different methods came to partially different results. Furthermore, it’s important to analyze a subject from more than one perspective and by using different methods.

     2. What are the differences between ISO9001:2008 and ISO9001:2015?

     

    The method that were being used to determine the differences that existed between the standard systems consisted of a gap-analysis. The analysis was carried out by comparing the following demands in ISO9001:2015 and its correlation in ISO9001:2008 and the difference (the gaps) could be identified (Figure 11).

     3. Which auxiliary tools are suited for companies facing a simple and effective transition to ISO9001:2015?

    The current situation has been put in relation to three important and critical factors which, according to Poksinska[8], are crucial when implementing a new standard. Relevant tools have been designed based on these factors to allow companies to ascend to the new standard in the best possible fashion. Companies must fulfill the new standards, determined by the gap-analysis, to be certified by ISO9001:2015. Relevant methods have been constructed from the difficulties and needs the companies experienced during the transition process as determined by O. Makie, B. Haxha thesis 2016 [2]. These methods can be directly applied to all Swedish companies, no matter what kind of business the company is conducting, to make the transition to ISO9001:2015 as simple as possible.

    The results from this thesis are the tools and methods that was produced and these have got their origin from the company’s current situation or from the gap-analysis. It has also been important to relate these tools and methods to the theory that has been processed to show their purpose and that they are supported by a scientific basis. The auxiliary tools can be directly applied and could come to be a part of the everyday quality management.

    On the deformation behavior and cracking of ductile iron; effect of microstructure2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis focuses on the effect of microstructural variation on the mechanical properties and deformation behavior of ductile iron. To research and determine these effects, two grades of ductile iron, (i) GJS-500-7 and (ii) high silicon GJS-500-14, were cast in a geometry containing several plates with different section thicknesses in order to produce microstructural variation. Microstructural investigations as well as tensile and hardness tests were performed on the casting plates. The results revealed higher ferrite fraction, graphite particle count, and yield strength in the high silicon GJS-500-14 grade compared to the GJS-500-7 grade.

    To study the relationship between the microstructural variation and tensile behavior on macroscale, tensile stress-strain response was characterized using the Ludwigson equation. The obtained tensile properties were modeled, based on the microstructural characteristics, using multiple linear regression and analysis of variance (ANOVA). The models showed that silicon content, graphite particle count, ferrite fraction, and fraction of porosity are the major contributing factors that influence tensile behavior. The models were entered into a casting process simulation software, and the simulated microstructure and tensile properties were validated using the experimental data. This enabled the opportunity to predict tensile properties of cast components with similar microstructural characteristics.

    To investigate deformation behavior on micro-scale, a method was developed to quantitatively measure strain in the microstructure, utilizing the digital image correlation (DIC) technique together with in-situ tensile testing. In this method, a pit-etching procedure was developed to generate a random speckle pattern, enabling DIC strain measurement to be conducted in the matrix and the area between the graphite particles. The method was validated by benchmarking the measured yield strength with the material’s standard yield strength.

    The microstructural deformation behavior under tensile loading was characterized. During elastic deformation, strain mapping revealed a heterogeneous strain distribution in the microstructure, as well as shear bands that formed between graphite particles. The crack was initiated at the stress ranges in which a kink occurred in the tensile curve, indicating the dissipation of energy during both plastic deformation and crack initiation. A large amount of strain localization was measured at the onset of the micro-cracks on the strain maps. The micro-cracks were initiated at local strain levels higher than 2%, suggesting a threshold level of strain required for micro-crack initiation.

    A continuum Finite Element (FE) model containing a physical length scale was developed to predict strain on the microstructure of ductile iron. The material parameters for this model were calculated by optimization, utilizing the Ramberg-Osgood equation. The predicted strain maps were compared to the strain maps measured by DIC, both qualitatively and quantitatively. To a large extent, the strain maps were in agreement, resulting in the validation of the model on micro-scale.

    In order to perform a micro-scale characterization of dynamic deformation behavior, local strain distribution on the microstructure was studied by performing in-situ cyclic tests using a scanning electron microscope (SEM). A novel method, based on the focused ion beam (FIB) milling, was developed to generate a speckle pattern on the microstructure of the ferritic ductile iron (GJS-500-14 grade) to enable quantitative DIC strain measurement to be performed. The results showed that the maximum strain concentration occurred in the vicinity of the micro-cracks, particularly ahead of the micro-crack tip.

    Accelerating from Zero to Global Hero: A Multiple-Case Study of Accelerators promoting Participants to become Born Globals2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In recent years, accelerators have gained increasingly attention due to their numerical growth, geographic dispersion, and growing numbers of participants they have worked with.

    Uber, Airbnb, Dropbox or Reddit – they have not only been participants of accelerators, but they can also be identified as ‘Born Globals’ according to the definition used throughout this thesis. Considering this fact and the lack of research in theory on the interrelation of both phenomena, accelerators and Born Global, it is interesting to dig deeper into the impact accelerators have on their respective participants’ global development.

    For this purpose, the authors conducted a multiple-case study to find answers to the question of what elements of accelerators promote participants to become Born Globals. This multiple-case study included semi-structured interviews with managers of four different cases of accelerators and three respective former participants as well as complementarily used secondary data in terms of company documents.

    Drawing from empirical evidence, it was found that the major elements of the examined accelerators fostering the participants’ development towards Born Globals can be summarized into five major categories: ’Application Process’, ’Interpersonal Connections’, ’Product & Coaching Methodologies’, ’Education’, and ‘Startup Community & Entrepreneurial Ecosystem’.

    Abstract [la]

    Fritidshemmet är en social arena där människor möts och tar del av varandras tankar, känslor och erfarenheter, vilka bidrar till att olika typer av relationer skapas och upprätthålls. Studiens syfte var att söka kunskap om vad barn beskriver viktigt för att skapa och upprätthålla relationer med kamrater och pedagoger på fritidshem. I studien fokuseras följande forskningsfrågor;

    • Hur beskriver barn trygghet?
    • Vad beskriver barn är viktigt för att bygga och bibehålla trygga samt förtroendefulla relationer med fritidslärarna och andra barn?
    • Hur arbetar fritidslärarna för att främja trygga och förtroendefulla relationer med barn och mellan barn på fritidshem?

    Teoretiska utgångspunkter i den här studien är sociokulturell teori och Vygotskijs tankar om lärande och utveckling. Studien genomfördes med kvalitativ forskningsmetod genom en etnometodologisk ansats. Vid analysen skapades följande teman: Trygghet och att vara tillsammans, Vänskap och intressen, Att förhålla sig till regler och normer, En bra pedagog.   Resultatet visar att trygghet och att vara tillsammans innebär att ha någon nära, det kan vara en vän med ett gemensamt intresse eller en pedagog som finns till hands.

    Precis! Det är majoritetens beslut liksom: En studie som belyser betydelsen av barns gemenskaper på fritidshem.2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I barnens vardag i fritidshemmet och i skolan befinner sig barnen i flera olika gemenskaper där de får olika mycket inflytande hos varandra. Syftet med denna studie var att undersöka vilken betydelse olika gemenskaper får för barns vardag i fritidshemmet. För att undersöka detta ställdes följande forskningsfrågor: Vad får barns kultur för betydelse för barns gemenskaper? Hur upprätthålls och förändras olika roller i barns gemenskaper? Studien har utgått från Goffmans (1959) teori om hur det sociala livet skapas i gemenskaper som sedan satts i relation till Johansson (2003), Qvarsell (2003) och Sparrmans (2006) beskrivning av barns perspektiv och kultur. Studien har tagit sin utgångspunkt i den kvalitativa forskningsstrategin där semistrukturerade intervjuer använts som metod för samtalspromenaderna och fokusgruppsamtalen. Studien visar att begreppet popularitiet innefattar olika egenskaper som att vara duktig och kunnig på flera olika saker. Barnen beskriver att det är skillnad på att vara kompisar och bästa kompisar, en bästa kompisa är någon som barnen beskriver att de känt under en längre tid. Barnen beskriver att avundsjuka är något som kan uppstå mellan varandra om de väljer att leka med andra kompisar eller vid de tillfällen där barnen visar för mycket av sin kunskap inför varandra. Barnen beskriver att de använder sig av olika strategier för att stärka sina kompisgemenskaper vilket kan leda till att barn utesluts från gemenskapen.

    LOMAH in a Box: Produktutvecklingsprocess2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This report presents a bachelor thesis in Mechanical Engineering, Product development and design and has been carried out in collaboration with SAAB Training & Simulation in Huskvarna. The thesis project involved a product development process beginning with establishment of specifications and concept generation through 3D modelling which then resulted in a complete prototype. The task presented by SAAB Training & Simulation consisted of developing a portable combined target holder and transportation case for their current livescoring projectile monitoring system, the LOMAH 700.

    A theoretical background was necessary to gain an understanding of the complex nature of a product development process and the stages involved. Different concept generation and evaluation methods were explored, including the Go/No-go and Vendor Evaluation Matrices, as well as engineering practices such as Design for Manufacturing and Design for Assembly. Various materials and production techniques were also investigated to optimize functionality of the product, as well as cost of production.

    The methods researched in the theoretical background were then applied throughout the development process. Brainstorming was used to generate numerous different ideas which were then evaluated using three different matrices. This resulted in one leading concept which was further developed through detail work and review. The work continued with 3D-modelling and drawing using SolidWorks to ultimately produce the grounds for manufacturing.

    The final concept consisted of a transportation case ordered from the case manufacturing company, SKB Cases. Custom-made components included legs with adjustable length and angle and a target holder used for fixing a target and the LOMAH 700 onto the transportation case. The custom-made parts were produced by SAAB, and the prototype was then assembled. The prototype was ultimately tested to ensure the fulfillment of the specifications defined by SAAB Training & Simulation.

    "Matematik är mer än att bara minnas": En kvalitativ studie kring lärares förhållningssätt i det flerspråkiga matematikklassrummet2017Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The modern classroom of mathematic consists of several different languages ​​and nationalities. The multicultural classroom places high demands on the teacher to meet every individual's needs. In mathematics, there are more cognitive demanding areas than others, and multilingual students find themselves having greater difficulties with the tasks requiring a higher cognitive ability than with the routine tasks. Since mathematic is a problem-solving topic, it means that the mathematic teachers have a crucial role in teaching to enable the multilingual students to develop in mathematic.

    The purpose of this study is to clarify how the problems and limitations of multilingual students in mathematics affect teachers' teaching purpose and ways to help and support problem solving tasks, as well as how teacher consider using the researched success-factors in practice. The study is based on a theoretical perspective of ethnomathematic of learning and it is based on observations and a semi-structured interview of a classroom.  The study is an extreme case, which means that only one teacher has been observed and interviewed. 

    The result shows that the observed and interviewed teacher in a multilingual classroom relates to the identified success-factors both consciously and unconsciously. Success -factors are evident through communicative situations and the results show practical examples of how this is expressed in a multilingual mathematic-classroom.  The result also shows that education is influenced in a positive way by the multilingualism of the mathematics classroom, as it forces the teacher to reflect more on his teaching.  Therefore, the conclusion is that through communicative and interactive environments, multilingual students can come to their right in the mathematical subject.  The teaching of multilingual students can be positively influenced by opening opportunities for a permitting and open classroom climate.

    Uppsökande tandvård och upplevelser om dess effekt på oral hälsa hos beroende äldre2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte: Syftet med studien var att undersöka tandhygienisters erfarenheter av uppsökande tandvård och deras upplevelser om dess effekt på oral hälsa hos beroende äldre.

    Metod: Studien bygger på en kvalitativ metod med en induktiv ansats. Nio legitimerade tandhygienister som arbetar med uppsökande tandvård inkluderades i studien. Inklusionskriterier var tandhygienister som arbetade med uppsökande tandvård i minst sex månader och minst två år som tandhygienist. Exklusionskriterien var tandhygienister som arbetade mindre än tre dagar i veckan med uppsökande tandvård. Intervjuer utfördes och analyserades med hjälp av kvalitativ innehållsanalys.

    Resultat: Uppsökande tandvård upplevdes höja engagemanget hos vårdpersonalen gällande den orala hälsan. En tanke har väckts att den orala hälsan tillhör resten av kroppen. Okunskap och attityder kunde dock begränsa effekten av arbetet med munvård. Känsla av frihet samt meningsfullhet nämndes som fördelar med arbetet med uppsökande tandvård. Faktorer som behövde förändras för att arbetet med uppsökande tandvård skulle vara mer effektivt och den orala hälsan bättre hos de äldre var större samverkan mellan professioner, bättre ergonomiskt stöd samt stöd till vårdpersonal som upplevdes för stressad.

    Slutsats: Äldre individer på vårdboende upplevs fortfarande ha en eftersatt munhygien. Uppsökande tandvård uppfattas vara en insats som sätter den orala hälsan i fokus, men det finns faktorer som försvårar arbetet med munvård på vårdboenden, främst på organisationsnivå. Trots detta finns möjligheter för att kunna erbjuda en mer adekvat munvård.

    Det handlar om att lyfta olikheter2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna studie syftar till att ta reda på hur fritidslärare beskriver att de arbetar med inkludering av barn med ADHD, Aspergers syndrom och autism på fritidshemmet. Forskningsfrågorna fokuserar vilka strategier fritidslärare beskriver att de använder sig av för att inkludera dessa barn samt vad de beskriver hindrar och möjliggör inkluderingsarbetet. Studien har ett sociokulturellt perspektiv. Metoden för studien är kvalitativ och sex fritidslärare har intervjuats. Resultatet som framkom i studien var att strategier som fritidslärare använder sig av är att arbeta på ett lösningsfokuserat och flexibelt sätt på fritidshemmet. Att använda sig av anpassningar som exempelvis bildscheman och timglas framkom i resultatet. Några av lärarna använde sig också av muntligt förbereda barnen. Relationskompetens var viktigt, att prata om olikheter är en viktig strategi där man jobbar med acceptans för olikheter. Det som hindrar och möjliggör inkluderingsarbetet beskrev fritidslärarna var personalens utbildning och kompetens kring ADHD, Aspergers syndrom och autism. Annat som studiens resultat visade var att lokaler, barngruppens storlek, skolans resurser och kontakten med föräldrar är viktiga hinder respektive möjligheter i arbetet med inkludering av barn med denna problematik.

    Äldres upplevelse av dagliga aktiviteter efter fall: En kvalitativ intervjustudie2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Fall accidents are common among older people in Sweden. Despite that there is lack of studies about the affected person's experience after a fall. Purpose: The purpose of the study is therefore to describe how older people’s experience their daily activities after falling. Method: The study was a qualitative interview study with semi-structured interviews. Nine people 71-94 years old from south Sweden have been participating in the interview study. The collected data was analyzed with a qualitative content analysis. Result: The result was divided into three categories:  Feelings that affect the performance of activities, physical experiences that lead to limitations and strategies for managing everyday life. Many experienced tiredness, fear and anxiety after a fall. Even pain and impaired mobility occurred among the participants. The consequences after a fall were found to affect and limit the everyday life. Conclusion: Based on the results of this study the personal experiences, feelings and the experience of the fall had at least as much influence on the daily life as the physical injury.

    Abstract [en]

    The purpose of this thesis is to study how working teachers view the use of read-aloud as a pedagogical tool to develop pupils’ reading and writing skills. Four primary- school teachers have been interviewed for this study and they were chosen through a snowball sampling. The result shows that both the teachers in this study and previous research consider read-aloud as a pedagogical tool to have a positive effect on pupils’ development of reading and writing skills. The teachers in this study point out that teachers’ attitude towards reading is one significant aspect to pupils’ reading interest, but also that read-aloud allows a variation in the education. In this study, the result shows that the teachers believe that read-aloud activities contribute to the development of vocabulary, grammar, the ability to interpret and    make    connections    to    their   own experiences.

    Abstract [en]

    This paper presents a general model for businesses to work with their engineering assessments to challenge fluctuating requirements which is the result of a recently finished research project. The model is presented together with a case study of a company with a product that continuously is and must be adapted to a changing market to be alive at all. The company has developed a streamlined development process that is configured based on current needs from time to time. One keystone to make the mass customization possible to this company is the augmented synthesis and the automated assessment of the product variants rendered through the configured development process. The automated process of making the assessments and how it connects to the general model is also presented in the paper.

    Applying Connectivism to Engineering Knowledge to Support the Automated Business2017In: 24th ISPE International Conference on Transdisciplinary Engineering (TE2017): Transdisciplinary Engineering: A Paradigm Shift, IOS Press, 2017, 621-628 p.Conference paper (Refereed)
    Abstract [en]

    Maintaining products in an automated business includes digitalization and automation of engineering knowledge. When new products are to be developed, and introduced not only has the production processes be automated but also the knowledge regarding how the product should be constituted depending on customer requirements. One big challenge that companies of this kind face is how to make sure that the knowledge automated still can be understood by its stakeholders during the development project and after product release and through the whole product life-cycle, which might last for decades. In this paper, we present a method to navigate and share vast amount of knowledge in businesses with high degree of automated engineering. The method is based on the connectivistic view of knowledge were network formation and filtering are two corner stones which implies the utilization of graph theory together with electronic publishing functionality.

    Analysing Engineering Knowledge in CAD-models and Spread Sheets using Graph Theory and Filtering2017In: 24th ISPE International Conference on Transdisciplinary Engineering (TE2017): Transdisciplinary Engineering: A Paradigm Shift, IOS Press, 2017, 629-638 p.Conference paper (Refereed)
    Abstract [en]

    As the era of Knowledge Based Engineering (KBE) and design automation has evolved a big effort has been put to automate CAD-models to quick and accurately respond to changes of customer specifications. The automated knowledge in these KBE-systems is represented as sets of rules, sets that are continuously growing. Parallel to KBE-systems knowledge is also automated in spread sheets (were the cells can be viewed as rules in a KBE system).These spread sheets also tend to grow in number and complexity. The vision of reusing corporate knowledge through automating it in computer systems are now threaten by the fact that the complexity makes it hard to grasp and manage what was automated. Complexity management and graph theory are scientific fields addressing these types of problems. This paper describes how engineering knowledge stored in CAD-models and spread sheets can be analysed through the application of graph theory, visualization and filtering. Information models of CAD-models and spread sheets are developed and applied to a real industrial case to generate and analyse the content.

    The Flipped Classroom and Student Learning at Compulsory School in Sweden: A Longitudinal, Qualitative Study2017In: Journal of Education and Practice, ISSN 2222-1735, E-ISSN 2222-288X, Vol. 8, no 18, 77-86 p.Article in journal (Refereed)
    Abstract [en]

    This article presents the results of a longitudinal study at an elementary school where teachers and students used the Flipped Classroom teaching methodology. Longitudinal studies of how the Flipped Classroom can support student learning are of importance because this methodology has become quite popular of late. Notwithstanding this, there is currently lack of broad and deep knowledge of its effects at the elementary school level. The research object is therefore important to study and longitudinal studies can provide us with important results, which can be used in teaching practices. Data was continually collected via observations and interviews with teachers and students over a period of three terms. The theoretical framework used in the study is ‘life-world phenomenology’, which entails that the point of departure for the study is the students and teachers’ living experiences of how the Flipped Classroom shows itself in the context of their school-life. A central issue with respect to the data collection was that the researchers were as unobtrusive as possible during their observations, so as to not affect normal school activities. This was done so as to understand the abilities that the students developed and how their way of working at school changed. The results show that the Flipped Classroom had a positive influence on the majority of students since they developed a sense of agency in their learning which was demonstrated by their taking the initiative as they progressed with their learning. Furthermore, they developed problem-solving skills and came to believe in their own potential for success. However, this teaching methodology did not suit every student, because it entailed change that was difficult for some of them to deal with. This was the case with students who needed a traditional structure to their teaching and who were more comfortable when the teacher was the central figure in the teaching process.

    Abstract [en]

    Purpose: New Swedish energy requirements are defined as Near Zero Energy Buildings for both new construction and renovation, with the purpose of balancing energy entering and exiting the building. Vertical attic extensions through prefabricated module system containing loadbearing walls of cross laminated timber has, by international studies, shown the potential for time and cost efficiency during renovation projects. The purpose of this inquiry is to examine the possibility to apply this extension system for Swedish renovation projects on post-war residential buildings that are both cost effective and that satisfies new Swedish energy regulations.

    Method: The report aims to answer the questions through a case study. Initially a literature study describes the incentives of vertical attic extensions and renovation. Then through a document analysis of a reference building, energy and cost comparisons are carried out between an attic extension of cross laminated timber and wood construction assembled on site.

    Findings: The Swedish post-war housing stock shows high potential through renovation and attic extension, to positively influence the Swedish average specific energy use while simultaneously providing fast and cost effective urban densification. The heat insulating performance of cross laminated timber is, for an attic extension, equivalent that of an on-site assembled wood construction. However, calculations shows difficulties for post-war housing stock to achieve the requirements for Near Zero Energy Buildings. The cost for assembling extending structure and interior walls etc. reveals approximately 2,7 % savings with cross laminated timber.

    Implications: The report brings forth the possibilities regarding renovation of the Swedish post-war stock of multifamily housing and the advantages of doing so in combination with vertical attic extensions. There are good conditions for implementation of cross laminated timber walls even in Swedish extension projects, while having the potential to lower costs slightly and saving time in relation to on site construction. Even though the results depend a lot on the choice of prefabrication, the study has exposed a valid alternative for future attic extension projects. The report also reveals potential difficulties in achieving new energy requirements for renovation of older housing stock.

    Limitations: Verification of load capacity through constructional calculations are not performed in this inquiry.

    Calculating the life-cycle cost is not a part of this project, which instead focuses on economic efficiency during production.

    The report focuses its research at energy-saving measures and doesn’t concern measures regarding for example higher accessibility.

    Abstract [en]

    Although BIM today is a well-known practice, there are shortcomings, mainly within interoperability and communication. It is relevant to seek solutions through new work methods and not just through new technical solutions. There are difficulties in implementing new work methods, as the industry is known to be routine based. 

    The aim of the study is to clarify the need for increased efficiency in the design process in terms of model calculations, to investigate the possibilities for an improved work method for construction engineers. 

    To reach the goal, the data collection methods interview and literature study have been chosen. This have been chosen, in order to portray the reality of the business community as well as current research within the chosen problem area. 

    The study has generated factors, such as: a more frequent information exchange reduces the risk of information loss. Using standardised details as support for reporting provides the ability to mediate preservation of collective experience.  Interoperability can reduce double modelling (which today is a time-consuming part of the workflow). Using the model in more parts of the process as the model has great potential for this since it contains a lot of information. These factors can contribute to increased efficiency of the construction process in terms of model calculations. 

    The size of the company is not the only thing that factors in when dividing work load. Clear dialogue between disciplines can create better conditions at the start of projects. By connecting more of the design details to the model it can be used in several stages, such as in the inspection phase. For the development of the preservation of experience, a library of construction details for support in design is recommended. Another recommendation is to start the collaboration between the construction engineer and the architect at an earlier stage, to facilitate their work processes. 

    The results of the study are nationally applicable. The factors relating to efficiency in cost, time and quality have only been studied briefly. The interview methodology applied to the study limits the generalizability when interpretation of opinions is carried out.

    Boende på vatten – en utredande studie om den flytande bostadens förutsättningar i Sverige2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The housing shortage affects everyone and in the future, we have to think about social, ecologic and economic sustainability in architecture and urban planning. Floating houses has the potential to satisfy all these requirements but in Sweden they have a hard time to settle as a concept. This study aims to investigate the possibilities and setbacks for floating homes in Sweden.

    Method: The methods of research in this investigation is qualitative. The collection of empirical data is done through semi-structured interviews, observation and analysis of documents.

    Findings: The biggest problem areas that we discovered was economy, law and technical solutions. Worry about the possible technical problems was only put forth by respondents who had little or none experience in working with floating homes. The main technical differences between a floating home and one on dry land is that the plumbing goes in the floating device instead of the ground, the connection between the house and the floating device and that a floating property doesn´t need any groundwork done. The cost of a floating house is often similar to one on dry land. The economic issues are uncertainty and inexperience, these factors can make the construction of a floating house more expensive. The area that contains the most problems for floating houses is the juridical. The process of getting a building permit is longer due to the extra number of laws and agencies involved.

     Implications: Municipalities needs bigger freedom in deciding land exploitation   to make it easier for floating houses to be an established concept in Sweden. The detailed development plan needs to include water areas. Another thing that will help is more completed projects, more projects for reference means more knowledge about the concept, instead of it being seen as just a luxury.

    Limitations: The investigation refers to Sweden as the geographic region. We interviewed respondents from agencies, entrepreneurs and property owners and the answers can only be seen as representative for those groups. Sketches of a floating home, a deeper calculation of the economy and precise law changes are not included in the thesis and are therefore suggestions for further research.

    Keywords: Alternative housing, alternative land use, floating houses, housing shortage, living on water, shoreline protection, urban development.
