    Conceptual Design of a Novel Continuous Nanoparticle Production Equipment for Energy Efficient Sintering and Additive Manufacturing2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Materials in nanoscale possess interesting features such as depression of melting point, increased chemical reactivity, improved mechanical, electrical and thermal properties. Today, nanoparticles (NPs) are generally produced using chemical synthesis routes and other top down methods. These processes suffer generally from issues such as low production yield and require complex precursors that may have large environmental concerns. NPs, especially spherical NPs, are very interesting in bringing down sintering temperature for sinter alloys and act as nucleation sites for crystal growth in, for instance, additive manufacturing processes. These features lead to decreased energy consumption and improved mechanical performance of additively manufactured products. Therefore, manufacturing of NPs in large scale is of great interest for future industrial development.

    The purpose of the present thesis work is to carry out a feasibility design study for a novel nanoparticle manufacturing equipment concept using a novel two coupled axis concept for producing NPs in larger quantities.

    The method is based on Consumable Electrode Direct Current Arc (CEDA, also called spark erosion) using two vertically aligned parallel electrodes, thus significantly increasing the yield of the NPs production. Before the start of the design work, a theoretical study was carried out to understand the state-of-the-art of the nanoparticle manufacturing processes available. It was followed by a novel design concept for a new equipment that can dramatically increase the yield of the NPs production compared to the state-of-the-art. The work is carried out using the Software Solidworks2016. A 3D model of the new machine concept using the novel design was built. A simulation of the control system based on the Software Proteus was carried out.

    This novel equipment can potentially offer continuous and larger scale and production of NPs which is useful for energy efficient sintering and for efficient control of grain size in additive manufacturing process, thus making a better product in the fast-growing additive manufacturing business sector.

    Image of China: Chinese attempts to purchase SAAB in Swedish and American Media2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Many Chinese car companies have attempted to invest in and purchase famous Swedish companies, which attracted a lot of attention of the media, particularly in Sweden and America. The investment is a complex transaction when companies from two countries are involved and are much different. This difference is the starting point for this study.

    This thesis aims to analyze the image of China in Swedish and American media. The study suggests that the representation of China in three newspapers is deeply rooted in ideology. Theories on media representation are applied and used in a qualitative analysis in order to present how the image of China is constructed. Through analyzing the twenty-five selected samples to explore how the media understood the Saab event and how they understood Chinese financial power. The main theoretical concept of the thesis is ideology, which is used to analyze the potential meanings of the Swedish and American notions of China. The findings show that both positive and negative images of China were portrayed by Swedish and American media. Furthermore, Chinese political leaders played an important role in the economic activity were also a central theme.

    Effects of surface finish on the initial oxidation of HVAF-sprayed NiCoCrAlY coatings2019In: Surface & Coatings Technology, ISSN 0257-8972, E-ISSN 1879-3347, Vol. 364, p. 43-56Article in journal (Refereed)
    Abstract [en]

    Oxide scale formed on HVAF-sprayed NiCoCrAlY coatings and the effect of surface treatment were investigated by a multi-approach study combining photo-stimulated luminescence, microstructural observation and mass gain. The initial oxidationbehaviour of as-sprayed, polished and shot-peened coatings at 1000 °C is studied. Both polished and shot-peened coatings exhibited superior performance due to rapid formation of α-Al2O3 fully covering the coating and suppressing the growth of transient alumina, assisted by a high density of α-Al2O3 nuclei on surface treatment induced defects. Moreover, the fast development of a two-layer alumina scale consisting of an inward-grown inner α-Al2O3 layer and an outer layer transformed from outward-grown transient alumina resulted in a higher oxide growth rate of the as-sprayed coating.

    Isothermal oxidation behavior of HVAF-sprayed NiCoCrAlY coatings: Effect of surface treatment2017In: Proceedings of the International Thermal Spray Conference & Exposition (ITSC 2017), New York: Curran Associates, Inc , 2017, Vol. 1, p. 456-461Conference paper (Refereed)
    Abstract [en]

    NiCoCrAlY coatings are widely used as bond coats for ceramic thermal barrier coatings (TBCs) andoxidation and corrosion protective overlay coatings in industrial gas turbines. High temperature oxidation behaviour of NiCoCrAlYs has a great influence on the coating performance and lifetime of TBCs. A promising route to decrease the oxidation rate of such coatings is post-coating surface modification which can facilitate formation of a uniform alumina scale with a considerably slower growth rate compared to the as-sprayed coatings. In this work, the effect of surface treatment by means of shot peening and laser surface melting (LSM) on the oxidation resistance of high velocity air-fuel (HVAF) sprayed NiCoCrAlY coatings was studied. Isothermal oxidation was carried out at 1000⁰C for 1000h. Results showed that the rough surface of as-sprayed HVAF sprayed coatings was significantly changed after shot peening and LSM treatment, with a compact and smooth appearance. After the exposure, the oxide scales formed on surface-treated NiCoCrAlY coatings showed different morphology and growth rate compared to those formed on as-sprayed coating surface. The oxidation behaviour of surface treated HVAF-sprayed NiCoCrAlY coatings were revealed and discussed.

    A discussion of methods and strategyfor spot welding localization calibration2015Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Spot welding is one of the most important welding procedures. Robots are used to perform the welding operation in dangerous and high temperature environment. This technology is to a large extent used in automotive industry to join plates. Specifically, in this work the joining of two plates of a car door is studied for the purpose of making it possible to decrease folded size and thereby materials used and as a result reduce weight of the product. There are many factors adding to uncertainty from the physical world such as noise of the welding machine, weld process or the signals, which all add up related to tolerances in control of the welding process The task of the research in this study is to control spot welding process in order to reduce tolerances and the plate folded size. A sensor system was developed and is described in this report. Universal methods based on laser scanner and cameras are introduced and the advantages and disadvantages of these are discussed. An optimized method based on universal methods with a strategy to meet the timing demands is developed. Experiments are performed to test the methods with ABB robot. The whole sensor system including the communication is built up and the algorithms are executed by programs.     The accuracy of the camera based method is tested in experiments. The result is promising and indicate feasible methods and strategy to locate the spot welding location during operation and thereby make it possible to achieve better welding quality with minimized increasing in cycle time.     Future work should be directed towards to choose a proper laser scanner and to create better mathematical model for the strategy in order to implement this in a real production environment.

    Determination of local residual stress in an air plasma spray thermal barrier coating (APS-TBC) by microscale ring coring using a picosecond laser2019In: Scripta Materialia, ISSN 1359-6462, E-ISSN 1872-8456, Vol. 167, p. 126-130Article in journal (Refereed)
    Abstract [en]

    A picosecond laser for incremental annular trench cutting is combined with digital image correlation (DIC) to extend the incremental ring-core method to the profiling of residual stress in thick (>100 μm) coatings. In this case the local residual stress in a TBC is depth profiled after exposure to 1150 °C for 190 h. The topcoat was found to be in compression with an average compressive stress of −94 ± 8 MPa which is representative of the stresses that would be generated elastically on cooling from a stress-free temperature of ~970 °C. The stress profile measurements have been validated by high-energy synchrotron X-ray diffraction measurements. © 2019

    Simulation of a production line in Robot Studio: Modelling and simulation2015Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    With the development of science and technology, production system in modern factories is more complex than it used to be. In order to cut unnecessary loss and protect operators from failure, simulation plays an essential role on testing production lines. In this thesis work, the model of production lines, located in Production Technology Centre (PTC) of University West were built with NX, Autodesk Inventor and simulated with Robot studio. And the production line includes three robot cells (milling machine work cell, turning machine work cell and conveyance work cell, respectively), a gantry robot and some auxiliary equipment, i.e. tables, computers, human task console. Signals were added to make sure the model could work as reality.

    Different measurement methods were used in order to locate production line components at right positions due to their importance to the accuracy of simulation. Measurement methods were also compared with each other to show the error. For instance, the error of CAD models, measurement, and the distance error among equipment, etc.

    Investigation of interfacial properties of atmospheric plasma sprayed thermal barrier coatings with four-point bending and computed tomography technique2012In: Surface and Coatings Technology, ISSN 0257-8972, Vol. 206, no 23, p. 4922-4929Article in journal (Refereed)
    Abstract [en]

    A modified four-point bending test has been employed to investigate the interfacial toughness of atmospheric plasma sprayed (APS) yttria stabilised zirconia (YSZ) thermal barrier coatings (TBCs) after isothermal heat treatments at 1150°C. The delamination of the TBCs occurred mainly within the TBC, several to tens of microns above the interface between the TBC and bond coat. X-ray diffraction analysis revealed that the TBC was mainly tetragonal in structure with a small amount of the monoclinic phase. The calculated energy release rate increased from ~50J/m -2 for as-sprayed TBCs to ~120J/m -2 for the TBCs exposed at 1150°C for 200h with a loading phase angle about 42°. This may be attributed to the sintering of the TBC. X-ray micro-tomography was used to track in 3D the evolution of the TBC microstructure non-destructively at a single location as a function of thermal exposure time. This revealed how various types of imperfections develop near the interface after exposure. The 3D interface was reconstructed and showed no significant change in the interfacial roughness after thermal exposure. © 2012 Elsevier B.V.

    Bottleneck detection through simulation software2015Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Bottleneck detection in production is essential to improve the overall manufacturing capacity. The common bottleneck detection methods have drawbacks of either practicability or accuracy. There is a recent manual methodology called bottleneck walk which is simple, accurate and easy to implement. Though it is a reliable and practical manual method, other more automated non-manual methods for detecting bottlenecks should be considered in the future. In this paper, the simulation models were built in a discrete event simulation software named Plant simulation. The models are based on real production cases where the bottleneck walk methodology had been tested. In the first case, the particular result shows that machine 2 has been the bottleneck for a long period, which is what is found in the real production. In the second case, the bottlenecks are found and the potential improvements are made on it. Though two improvement plans are made, neither of them solves the bottleneck and im-proves the system output. The plan of reducing buffer size might probably have an improve-ment on financial aspect. And further improvements on all findings remain available on models built in this paper.

    Representations of Chinese People in Hollywood Martial Arts films2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis aims to analyze the stereotypical images of Chinese people and how these have changed between the late 1960s and late 1990s in Hollywood martial arts films. There is much literature about the stereotypical images of Chinese people in certain time periods, however, among the existing scholarship so far few have investigated changes in the time period we analyze. This thesis uses social constructivism and representation as main theories and combines these with the central concept of racialization and stereotypes. Moreover, this thesis is constructed as comparative design tha applies qualitative discourse analysis in order to analyze the stereotypical images of Chinese people. We analyze the characteristics of Chinese characters and relationships between Chinese and American characters in three Hollywood martial arts films. The findings show that the images of Chinese people change over time, from an earlier negative image to a subequent positive image. The Chinese characters also gradully become leading parts and take more and more place in Hollywood martial arts films. Our thesis contributes to the existing literature on stereotypes and films research.

    Exchange Rate Risk Management at Chinese Small- and Medium-Size Enterprises2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The topic of this thesis concerns how Chinese SMEs manage foreign exchange risk. Since the financial reform in 2005, China has adopted the managed floating foreign exchange system and Chinese companies have to face the risk bought by exchange rate. Chinese companies have realized the damage and loss, which is caused by foreign exchange exposure and it, is more essential for Chinese companies to build risk management for identifying, assessing and responding to foreign exchange risk. In general, there are financial hedging tools when companies respond to foreign exchange risk, such as forward hedging, option hedging and so on, and operating hedging tools can be potential options for Chinese SMEs to use. Compared to the large companies, Chinese SMEs have few resource and ability to build their risk management and few channels and tools to deal with foreign exchange risk and diminish the loss. There are researches that have been done on how SMEs deal with foreign exchange and the hedging tools these SMEs use. But only few research relates to Chinese companies and even few research talks about Chinese SMEs and how they conduct risk management and what tools they have. The purpose is to fill in this blank.

    This research adopts qualitative research strategy and is based on the interview with owner or financial managers of Chinese SMEs. Authors adopt a qualitative case study to collect empirical evidence and invite five interviewees for data collection. These Interviewees are CEO or financial managers of Chinese SMEs.

    Through the research, authors find the appreciation of Chinese Yuan (CNY) is the main threat to Chinese SMEs. Although most of Chinese SMEs have realized the foreign exchange exposure, only part of Chinese SMEs has risk management towards the risk. Most Chinese SMEs use operating hedging tools to deal with transaction exposure and economic exposure. But only part of Chinese SMEs can use financial hedging tools to handle transaction exposure because they have resources and ability to use these tools. In the other hand, forward hedging is chosen by most Chinese SMEs and the banks which have permission from government to offer forward service are the only channel for Chinese SMEs to use forward hedging tool. Lack of knowledge, resources and capability is main challenge for Chinese SMEs in forecasting future exchange rate, building risk management and conducting risk response to foreign exchange exposure.

    Is there an EMU effect on trade inside the Eurozone?2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A major economic reason for the development towards Economic and Monetary union of European union (EMU) was the extensive view that it would enhance trade between the member countries. The aim of this paper is to estimate if there is an EMU effect on trade for the countries inside the Eurozone, and in addition look how trade is affected between EMU members and countries outside the currency union. A panel data set has been used, covering bilateral trade from 10 developed countries, for the years 1995 to 2013. The regression is run on two different groups, one including all OECD countries in the sample, and one using data from only the European Union countries in the sample. I estimated that the adoption of the Euro inside the Eurozone has increased trade between 16 and 17,5 percent. Furthermore, i found that trade from Eurozone to outside countries has increased between 9,4 to 21 percent. After implemented yearly dummy variables for the Eurozone it can be detected that the EMU effect on trade has increased over time, from 10,3 percent in 1999 to 29 percent in 2013.

    Ledarstilar: en studie om vilken ledarstil som är mest optimal enligt medarbetarna2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The study's purpose was to examine which leadership style that is the most optimal according to the employees, and examine if any of the existing line managers in the investigated company possesses the characteristics that the most optimal leadership style is based on. The study is important, in particular for the investigated company, but also for other companies and their executives for the reason that the results from the study could help and pay attention to employees needs and to listen to what they want out of their line managers. This can counteract conflicts and reduce the number of employees that are unhappy with their line managers.

    Our empirical data is based on a qualitative study where we have held interviews with the three line managers and five employees in order to get opinion and thoughts about the line managers and their leadership styles. We have also done an observation of the line managers before the interviews to pick up important information and create a reasonably image of the situation for when the respondents answered our questions.

    The study has resulted in one line managers having the characteristics of a transactional leadership style while the other two had the characteristics of a transformational leadership style which also was the most optimal leadership style according to the employees.

    Ämnet svenska, till vilken nytta?: En jämförelse mellan gymnasieelevers och gymnasielärares uppfattning2009Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund

    Trots att dagens läroplan ger möjligheten att individualisera undervisningen, uppstår ändå skillnader mellan lärares och elevers syn på vad ämnet svenska innebär. Ett nyttoperspektiv ger större möjligheter att finna vilka skillnaderna är. Vid inhämtande av kunskap är motivationen en viktig faktor, där intresset är en viktig beståndsdel. Nyttan kan här ses som en motivationsfaktor.

     Syftet

     Att få en djupare förståelse och jämföra lärares och elevers uppfattning kring nyttan med ämnet svenska, vad de anser är viktigt och oviktigt, eller vad man lägger tyngdpunkten på i förhållande till läro- och kursplanen.

     

    Metod

     

    Undersökningsmetoden har varit kvalitativ med ett bekvämlighetsurval som grund. För att kunna få svar på frågeställningarna har fyra behöriga gymnasielärare och fyra gymnasieelever intervjuats. Metoden är vald för att ge en djupare förståelse av lärarnas och elevernas uppfattningar kring ämnet.

    Resultat

    Resultatet visar att uppfattningarna kring läroämnet svenska är individuella, både bland lärare och elever. Vissa skillnader mellan elevers och lärares syn kan urskiljas. Lärarna har en allmänt sett mer bred och djup definition av kunskap, eleverna har en mer ytlig, färdighetspräglad kunskapssyn. Lärarna lägger tyngd på färdighets- och bildningskunskaper, där läsandet och skrivandet är en viktig beståndsdel, medan eleverna efterfrågar en större betoning på muntliga kommunikationsfärdigheter som har anknytning till deras individuella intressen.

    Orsaker till låg följsamhet till handhygienföreskrifter: En litteraturöversikt2009Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Hand hygiene is the simplest and most fundamental means to prevent care related infections. It is of great importance that the guideline of hand hygiene is followed for the patient’s sake. Unfortunately, healthcare workers perform hand hygiene too seldom. If the patient comes down with a care related infection, the suffering will increase. The nurse's role is therefore to prevent unnecessary suffering for the patient by following recommendations for hand hygiene. In order to get a broader understanding of the reasons why the compliance of hand hygiene is so low the theory of planned behaviour was used (TPB). This theory explains the human behavior. Aim: The aim of this study was to describe causes of not following recommendations for hand hygiene among health care workers. Method: This literature review was based on quantitative and qualitative scientific articles. Results: The findings indicated that there were several factors that influence the low compliance of hand hygiene recommendations. These were summarized as: workload and lack of time, skin irritation, attitudes and motivation, insufficient access to hand hygiene products, inappropriate glove use, lack of knowledge and unawareness.

    Sjuksköterskans erfarenheter av att kommunicera med patienter via tolk2014Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: The number of patients with a foreign background is increasing, thereby it can be a challenge for the staff to communicate with those who do not speak the native language. Therefore, the need for good communication is crucial in order to meet patient’s right and secure the quality of nursing care. Interpreters are increasingly used in healthcare today, despite of this the communication between the nurse and patient does not work. Few studies are made where the communication between the nurse and patient through an interpreter is studied in the primary care in Sweden. Aim: The purpose of this study was to describe nurse’s experience of communication with patients through an interpreter in the primary care.

    Method: Eight nurses and district nurses were interviewed individually during winter 2013. The interviews were recorded and transcribed. A qualitative content analysis method was used to analyse the interview texts. Results: Four main categories were revealed: experiences of communicating through an interpreter, family member as an interpreter, professionalism among interpreters and strategies for the use of interpreters. It is a challenge to work through an interpreter since it require more time and resources. There are differences in the interpreter’s skills and to use relatives as interpreters is not optimal for the patient's autonomy. Nurses have their own strategies when it comes to the use of interpreters. In spite of this it is nurses pointed out the need for training in intercultural communication and training in effective use of interpreters. Conclusion: There is a need for better collaboration between the interpreter agency and the nurses there the views and expectations of both sides can be discussed. That could improve quality of the communication with the patient and provide the care that is planned. Training for nurses in intercultural communication should also be improved

    A comparative study on the performance of suspension plasma sprayed thermal barrier coatings with different bond coat systems2015In: Surface & Coatings Technology, ISSN 0257-8972, E-ISSN 1879-3347, Vol. 275, p. 276-282Article in journal (Refereed)
    Abstract [en]

    The performance of suspension plasma sprayed (SPS) yttria stabilized zirconia (YSZ) thermal barrier coatings (TBCs) after isothermal treatment at 1150. °C was investigated. The NiCoCrAlY bond coats were applied by air plasma spray (APS) and high velocity oxygen fuel (HVOF) techniques. It was found that the microstructure of SPS TBCs depends on the surface morphology of the bond coat. The SPS TBCs with a rough APS bond coat exhibited a longer lifetime than those with a smooth HVOF bond coat. To understand this phenomenon, the evolution of the microstructure, mechanical properties and the residual stresses in the TBCs and TGO were systematically studied. Results showed that the surface roughness and oxidation behavior of the bond coat play dominant roles in the SPS TBC failure. © 2015.

    Self-reported aggressive and antisocial behaviors in Moroccan high school students*2019In: Psihologija, ISSN 1451-9283, p. 1-13Article in journal (Refereed)
    Abstract [en]

    The aims of the present study were to map the level and distribution of aggressive and antisocial behaviors in a sample of Moroccan high school students and to define the level of these behaviors in adolescents who reported parental alcohol use problems and/or experienced abuse. In total, 375 high school students completed the "Mental and Somatic Health without borders (MeSHe)" survey that includes the Life History of Aggression scale. Male students had significantly higher scores for aggression and antisocial behaviors than female. The students who reported experience of abuse or parental alcohol use problems scored significantly higher for aggression, self-directed aggression, and antisocial behaviors compared to students not reporting these negative psychosocial factors. Previously shown gender-specific patterns in aggressive and antisocial behaviors, but not in self-harm behaviors were confirmed in these Moroccan high school students. Reported experience of abuse and/or parental alcohol use problems were associated with increased frequency of aggressive and antisocial behaviors.

    Somatic health and its association with negative psychosocial factors in a sample of Moroccan adolescents2019In: SAGE Open Medicine, E-ISSN 2050-3121, Vol. 7, p. 1-11Article in journal (Refereed)
    Abstract [en]

    Background: Adolescence is a distinct developmental phase characterized by multiple physical and psychological changes andby an increased vulnerability to somatic and mental health problems. These risk and vulnerability factors are part of a complexbiopsychosocial matrix, encompassing multiple factors, such as inherited biological determinants and psychological, societal,and cultural influences, which affect an adolescent's overall wellbeing. In Morocco, similar to other developing countries,adolescents (young people aged from 15 to 19years) constitute a substantial proportion of the population (almost 9%).However, studies about adolescents' health in developing countries are scarce. In this study, we describe adolescents' somatichealth in a sample of high school students from the city of Tetouan, Morocco, and investigate how negative psychosocialfactors, such as parental alcohol use problems and/or the experience of abuse, may influence them.Methods: The study sample included 655 adolescents (315 boys and 340 girls, M=16.64years, range=15–18years) fromconviniently selected classes of four high schools in the city of Tetouan in Morocco. The students responded to a survey thatassessed the prevalence of somatic complaints/disorders. They also indicated whether they had ever experienced physicaland/or psychological abuse and whether they had parents with alcohol use problems.Results: More than half of the adolescents suffered from headaches and one-third had substantial problems with diarrhea orconstipation. Both problems were more common in female students. The third most frequent somatic problem, affecting onein four in both genders, was allergy. Almost one-third of Moroccan adolescents (significantly more boys than girls; p=0.004)reported no somatic complaints. In adolescents who reported parental alcohol use problems and/or experience of physicaland/or psychological abuse, the prevalence of several somatic complaints (epilepsy, migraine, headache, diarrhea/constipation,gluten intolerance, allergy, and skin or thyroid disease) increased highly significantly compared to the adolescents whoreported no such psychosocial environmental factors.Conclusion: The results suggest that only 3 in 10 urban-living Moroccan adolescents are free of somatic complaints, whilethe majority suffer from some somatic problems, most often headaches and diarrhea/constipation. The association of certainnegative psychosocial factors with adolescents' somatic health suggests the need of a holistic approach to the treatment of affectedadolescents.

    Parameterstudie om lasersvetsning av en nickelbaslegering2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The bachelor's thesis has been performed at Siemens Industrial Turbomachinery AB in Trollhättan, Sweden. The aim of this bachelor's thesis was to identify problem in a welding process in order to improve the weld quality. Based on statistical experiment four factors were evaluated with DOE method and ten experiments in material 2 mm Hastelloy X was performed with Siemens fiber laser (3D Prima Laserdyne 795). The factors weld speed,shield gas, focal point and laser power were the four welding parameters that varied in the experiment, in order to evaluate the factor effects on pores and joint geometry in the welds. Plane test plates were created to the experiments and brainstorming with the personal at Siemens in order to identify which factors to choose for the experiments. To evaluate pores and joint geometry the test plates was x-rayed, sectioned, polished and etched. Joint geometry was measured and photographed with microscope. Statistical analyze was performed with Minitab to estimate the factors effect on pores and joint geometry.Problem in the weld process was identified based on the ten experiments, which werepores and critical dimensions for the joint geometry. A conjunction for the pores and joint geometry was identified. The conjunction was if pores occur in the weld joint the joint geometry affects negatively too, but it's not statistical verified. The weld process have been identified to be unstable based on the statistical analyze that been performed. The weld process needs to be further evaluated, to identify confounding factors, which affect the stability of the welding process. One of the ten experiments was closest to the criterias for approved weld joint. The experiment that was closest to the criteria's for approved weldjoint is recommended for further work to Siemens. The welding parameters that are recommended to be evaluated further are laser power and the interaction factor welding speed and shielding gas, which can have a significant impact on the pores and joint geometry based on the statistical analysis performed by Minitab.

    Filosofin i barn- och ungdomslitteraturen: en studie kring filosofiska tankegångar i Nalle Puh, Liftarens guide till galaxen, Hungerspelen och Flugornas herre2015Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Uppsatsen syftar till att undersöka om barn och ungdomslitteraturen tillägnat sig filosofiska tankegångar och hur detta har utryckts i fyra skönlitterära verk. Barnlitteraturen används i skolan framförallt för att öka läsförståelse och ordkunskap. I denna studie har jag pekat på att litteraturen även kan föra fram filosofiska idéer. Uppsatsen kan fungera som en vägvisare till hur filosofiska idéer kan hämtas från skönlitteraturen och på så sätt exemplifiera dessa med hjälp av litteraturen, men också hur vi på samma sätt kan göra litteraturen mer begriplig med hjälp av filosofiska exempel. Uppsatsen har visat att barnlitteraturen innehåller djupa och intressanta filosofiska tankegångar. Både äldre och nyare barnlitteratur kan därför med fördel användas i skolan för att introducera filosofiska begrepp på ett stimulerande sätt.

    Brukarinflytande - en fråga om att bruka makt: En kvalitativ studie om brukarinflytande för personer med psykiska funktionsnedsättningar2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Föreliggande studie avser att öka förståelsen för hur boendepersonal ser på och arbetar medbrukarinflytande för personer med psykiska funktionsnedsättningar. För att kunna göra detta formulerades tre forskningsfrågor, vilka avser att undersöka boendepersonals syn på syftet med brukarinflytande, deras upplevelse av hur de kan främja respektive hindra förutsättningar för brukarinflytande samt vilken påverkan brukarinflytande kan ha på deras arbete. För att kunna besvara studiens frågeställningar har fem kvalitativa intervjuer genomförts med personal på boenden för personer med psykiska funktionsnedsättningar. Studien har vidare analyserats utifrån följande teoretiska utgångspunkter; det relationella maktperspektivet, Franzéns makttriangel, den professionella makten och brukarrollen, handlingsutrymme samt paternalism och empowerment. Resultatet visar att brukarinflytande har en föränderlig karaktär och varierar i utformning och styrka beroende på kontext och brukarens personliga förutsättningar. Det framkommer flera argument för brukarinflytande. Vissa syftar till att öka brukarnas empowerment och främja deras återhämtning, dessa kan i hög grad kopplas till olika kategorier av brukare. Andra syften gynnar verksamheten och boendepersonal. Resultatet visar vidare att inte heller arbetet med brukarinflytande är helt okomplicerat. I detta arbete återfinns flera hindrande faktorer och aktörer på olika nivåer. Hindren påverkar vidare hur boendepersonal kan använda sin professionella makt och sitt handlingsutrymme i arbetet med brukarinflytande. Det finns också argument för att boendepersonal ibland begränsar eller hindrar brukarinflytande, exempelvis att det sker med hänsyn till brukarens bästa. Resultatet visar att det finns personal med paternalistiska förhållnings- och arbetssätt, vilka utgör hinder för brukarinflytande. Genom kommunikation kan boendepersonal dock skapa förutsättningar för brukarinflytande i personalgruppen, på så sätt kan den stigmatiserande diskursen om personer med psykiska funktionsnedsättningar ifrågasättas. Vidare visar resultatet att boendepersonal även kan främja brukarinflytande genom att öka brukarnas empowerment samt genom att inta ett empowermentinriktat förhållningssätt. Detta balanserar makten i relationen och möjliggör en mer jämlik relation, vilket uppfattas främjande. Boendepersonal kan också främja förutsättningarna för brukarinflytande genom att välja hur de ska hantera sitt handlingsutrymme, exempelvis genom att avsätta tid för brukarinflytande. Resultatet visar vidare att boendepersonals upplevelse av hur brukarinflytande påverkar deras arbete beror på inflytandets utformning. Det är dock tydligt att brukarinflytande ställer ökade krav på boendepersonal och deras arbete, vilka många gånger upplevs svåra att tillmötesgå på grund av tidigare nämnda hinder. Brukarinflytande kan också ha en positiv påverkan för boendepersonals arbete, dels då det kan underlätta arbetet och fylla en vägledande funktion och dels då det fyller en bekräftande och utvecklande funktion. Min slutsats är vidare att brukarinflytande för personer med psykiska funktionsnedsättningar varken är självklart eller enkelt. Men genom att öka förståelsen för det studerade området kan studien förhoppningsvis stimulera till reflektion och diskussion hos anställda inom socialt arbete, vilket kan främja förutsättningarna för brukarinflytande för personer med psykiska funktionsnedsättningar

    Abstract [en]

    The present study aims to, through a critical age perspective, describe and illustrate the structural conditions of the age category of children based on the information about treatment for gambling problems provided by municipal websites. The study has a quantitative character and in order to answer the study's questions, a content analysis of municipal websites (N = 119) was conducted. 52,1% of those websites contained information on treatment for gambling problems (n = 62). The result showed a statistically significant difference in the distribution regarding information by municipal websites on treatment for gambling problems ( χ² = 9,478a , df = 2, p = ,009) and treatment methods ( χ² = 13,400a , df =2, p = ,001) between the structural age categories. Throughout, age as an organizing principle was updated, and the age category of children was directed to information about treatment for gambling problems through municipal websites to a considerably lower extent than other age categories. This brought to light an age hierarchy and from a children perspective it is possible to state that children's structural conditions were unequal. When this was consistent, it is reasonable to assume that there is systematic inequality, which raises social stratification.

    The problem-presentation in integration work: Construction of information needs for newly arrived immigrants2016In: 44th NERA Congress is ‘Social Justice, Equality and Solidarity in Education?, 2016Conference paper (Other academic)
    Abstract [en]

    Today people migrate and leave societies that cannot secure human life and safety, where one's worth as a human is being violated. People are fleeing not only from, but also to places. When arriving to a new society it needs to be described, to make it possible to meet it and act in it. In dialogue and interaction with groups, society therefor must find and describe models for inclusion. In Sweden, as residence permits are obtained, so called ‘integration workers’ are engaged in Civic Orientation, to support the process by means of which individuals are to become knowledgeable enough to exert their agency as citizens (knowing your rights and obligations).

    The overall object is to create linkages between the state and the ‘newly arrived immigrants’. Civic orientation is a course for 60 h, regulated by Swedish law and EU has given directions that every member state is supposed to have some form of civic education, but every country is responsible for organizing and develop their own content. Often, in Sweden, the integration workers themselves have immigrated to Sweden and the course is given in the mother tongue of the immigrants.

    This study is a workplace study with interest in professional knowledge to create stable and flexible knowledge in the work, understood as how the workers construct relevance for their doings in interaction. In this study the specific interest is to understand the construction of newcomers' information needs, the problem being worked with. The need of information is understood as not given or static, but as a (re)produced in regular social practices (Edwards, 2005), and both integrationworkers and newcomers mutually orient to a set of ideas when constructing needs. The analytical interest is also to outline how some views is made more significant or more authoritative with respect to the matter at hand (Heritage and Raymond, 2005).

    In reasoning about needs, the access to countries, as epistemic domains is often used to make claims about what kind of information that is needed. In other words, the country that the immigrants comes from is often arranged to be the source of knowledge. The data material was generated through video recordings and interviews over a period of 1.5 years, from backstage (workmeetings) and frontstage work (with ‘newly arrived immigrants’). I identify two patterns that are analytically distinctive when looking at how the problem- presentation in civic orientation is negotiated. Either is it the knowledge about the Swedish society that is the matter at hand, or is it to educate those who have not yet come to a certain ´understanding´. This are two very different worktasks, but they seems to be connected in the practice.

    Romska kvinnor intersektionalitet och samhällsförändring: en studie av sju romska kvinnor som medverkar i ett integrationsprojekt2006Independent thesis Advanced level (professional degree)Student thesis
    Abstract [sv]

    Syftet med uppsatsen är att studera unga romska kvinnors identitetsskapande i det senmoderna svenska samhället, utifrån de sociala markörerna; kön, etnicitet och klass. Med uppsatsen vill jag även bidra till att nyansera synen och fördjupa diskussionen om romska kvinnors framtid i Sverige. Min studie utgår från sju romska kvinnor som ingår i ett kooperativt integrationsprojekt som ska leda till möjligheten att få ett arbete. Jag har använt mig av teorier om intersektionalitet, kön, klass och etnicitet, för att kunna studera hur dessa intra-agerar och påverkar varandra då kvinnorna (åter)skapar sina identiteter för att förändra sina positioner i samhället. Jag har också använt mig av fakta för att skapa en förförståelse om romers situation och diskriminering i det svenska samhället. Mitt empiriska underlag för uppsatsen bygger på material som är insamlat genom kvalitativa metoder som gruppintervjuer, enskilda intervjuer och observationer. I utredningar om romers marginalisering, upplever jag att det i allt för stor utsträckning fokuseras på "etnicitet". För att få en förståelse för hur kvinnorna förhåller sig till diskriminering och utanförskap måste vi ta hänsyn till intersektionen kön/klass/etnicitet. Vad jag har kommit fram till i min studie är att de sju kvinnorna aktivt skapar vad romskkvinna är. Eller som de själva benämner sig; Moderna romska kvinnor. De har skapat strategier för att förhålla sig till den diskriminering som de möter. För kvinnorna innebär arbete inte bara en ekonomisk förbättring, utan det leder även till jämställdhet och integration i samhället.

    Är gammal alltid äldst?: En jämförelse mellan yngre och äldre ledares ledarstil2009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Jag har i denna rapport studerat om det finns några skillnader mellan olika ledare beroende på deras ålder. Jag delade in respondenterna i tre olika ålderskategorier (unga, mellangamla, och gamla) och har sedan jämfört dessa kategorier med varandra. Som utgångspunkt beskrev jag hur vetenskaplig litteratur redogör för olika ledaregenskaper och olika ledarstilar. Som inledning förklarade jag skillnaden mellan chefskap och ledarskap, detta eftersom dessa begrepp lätt kan förväxlas. Chefskap innebär att man har fokus på att lösa uppgiften, och med ledarskap så har man även fokus på att utveckla medarbetarna, samt att dessa skall må bra och trivas på jobbet. I den valda litteratur redogjordes det för olika definitioner om vad ledarskap egentligen är, jag fann dock en tydlig röd tråd i de olika definitionerna och det var att ledarskap är en kombination av hur man löser uppgiften och vilken relation man som ledare har till sina anställda. Min utgångspunkt var att olika ledarstilar innebär hur kombinationen uppgiftsfokusering och relationen till anställda hanteras. Utifrån detta definierade jag fem olika huvudstilar som hanterar kombinationen uppgift/relation på olika sätt. När jag jämförde de olika ledarstilarna kom jag fram till att unga ledarna har mindre fokus på uppgiften jämfört med gamla ledarna, hos de mellangamla ledarna fanns det inget tydligt mönster. De unga ledarna hade någorlunda liknande ledarstil, en ledarstil med spår av en osäkerhet på vad man skall lägga fokus på. De mellangamla ledarna skiljde sig åt väldigt mycket, men hade till skillnad från de unga ledarna fokus på något område. De gamla ledarna liknade varandra och hade en fokusering som låg mest på uppgiften. När jag studerade olika ledaregenskaper var det tydligt att de unga ledarna jämfört med de gamla ledarna litade mer på sina anställda och lät dem agera mer fritt. Detta samtidigt som de utgick ifrån att medarbetarna skulle säga ifrån om de fick problem. Detta ligger i linje med att unga ledare har mindre fokus på uppgiften. Ytterligare skillnader var att unga ledare agerar mer kortsiktigt. De kommer också att lyssna mer på sina anställda innan de fattar beslut.

    Gendered Rhetoric in the UN General Assembly?: The Rhetorical Styles of Male and Female Representatives of Sweden and the United States2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    During the last few decades the academic re-gendering has reached the field of rhetorical discourse and differences of speech and rhetoric has been determined. Another gender shift has occurred during the last few decades in the appointments of foreign policy representatives, from being one of the last patriarchal strongholds the change towards equality has been remarkably swift. However, the norms of masculinity and formality within the sphere of foreign policy are still persistent. The first aim of this thesis was to determine if the rhetorical style of men and women differed even in a context heavily laden with norms, such as the UNGA. The secondary aim is based upon the concept of masculinity and femininity in culture, to determine if the gender of culture influenced the speaker’s rhetorical style, even in the UNGA. This thesis generates its own theoretical framework from the works of rhetoric and linguistics to separate masculine and feminine rhetorical style. The method used is a qualitative textual analyze applied to transcribed speeches held by Swedish and U.S. representatives in UNGA. The analysis proved that there is a difference in rhetorical style between genders and culture, even in a context such as the UNGA, but only a small one.

    Att rädda sitt liv istället för att ta livet av sig: en studie kring ungdomar och självskadebeteende2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Med denna studie har jag för avsikt att föra fram självskadebeteende från en annan vinkel. Syftet med studien var att diskutera faktorerna bakom ett självskadebeteende. Min studie är riktad mot personer som vill eller redan hjälper ungdomar med självskadebeteende, professionella, familj eller vänner. I studien diskuterar jag vad samhället idag klassar som självskadebeteende, hur mycket av beteendet som är ångestrelaterat, faktorer bakom beteendet samt hur mycket av beteendet som är kopplat till känslan av förlorad kontroll.

    Jag har intervjuat nio personer som arbetar med ungomar varje dag. Jag använde mig utav kvalitativ forskningsmetod. Resultaten av denna studie visar på att den största delen av ett självskadebeende är ett tecken på känslan av förlorad kontroll, ungdomen tar tillbaka kontrollen genom att självskada. Beteendet är ett tecken på ångest, vilket reduceras genom att självskada. Självskadebeteendet kan även orsakas av ohälsosamma relationer med vänner, familj eller andra relationer. Och resultaten visar på att samhället inte riktigt förstår beteendet och har en negativ bild av det, samhället har fortfarande uppfattningen av att självskadebeteende utgörs av en grupp vita små flickor som skär sig i handlederna.

    Att vara medvandrare i en andlig och existentiell livsvärld: En kvalitativ litteraturbaserad studie om sjuksköterskors erfarenheter av andliga och existentiella möten vid livets slut.2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: About 91000 people died in Sweden in 2016 and of those who died an estimate of 70000-75000 needed palliative care. When facing one’s own death it actualises questions about life and death and what happens thereafter. An important aspect of caring for patients at the end of life is the existential and spiritual dimension and therefore it is important that nurses have adequate knowledge and insight to be able to provide the best possible spiritual care for the patients. Aim: The aim of this study was to illustrate nurses’ different experiences of existential and spiritual encounters with patients at the end-of-life. Method: A method to contribute to evidence-based nursing with ground in analysis of qualitative research was used. An analysis of thirteen qualitative articles was carried out and resulted in 3 main themes and 12 subthemes. Results: The results of the study showed that some important factors with regards to existential encounters were courage, good communication skills, presence and the ability to care with love and compassion and to instill a sense of hope. For the nurses the encounters fostered a process of inner growth as they started to reflect on their own sense of spirituality and on issues of death and dying. Barriers included lack of time, knowledge and staff shortages. Conclusion: There is a need for sufficient time, education and support for the nurses to feel more prepared and comfortable in meeting the existential needs of the patients. Keywords: Palliative care, existential, spiritual, experience, nurse

    Under ytan: En socialpedagogisk studie om behandlingspersonals upplevelse av att arbeta med flickor som har ett självskadebeteende2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study is to increase the understanding of how the treatment staffexperience and handles the work with girls who self-injure . In order to answer thesequestions we interviewed six people working at two different institutions where theyworked with girls who self-injure.

    In this study, in summary, we see that it evokes many strong emotions in those who workwith these girls. We saw treatment staff expressing the need for support in their work tokeep work enjoyable but also to create an understanding of the girl's behavior.Treatment staff uses clear protocol dealing with a girl who is injured. The protocol arepartly for the other girls who live in the same housing so that there will not be a contagioneffect and partly for the individual girl who does not get the attention which otherwisewould reinforce the behavior.We also see that the treatment staff needs support in their work to maintain a goodtreatment for girls.

    Our conclusion is that the staff group is the most important asset the treatment staff feelthat they have at work. Education is one of the important ways through which thetreatment staff maintain their enthusiasm to their work. Belonging to a cohesive workgroup provides staff with a feeling of security at their job place. Within a work group thereare also opportunities to reflect on difficult events. This allows the possibility to processwhat they experienced. Treatment personnel can despite an established approach feelambivalence in their work.

    Electron backscatter diffraction characterization of fatigue crack growth in laser metal wire deposited Ti-6Al-4V2018In: Materials Characterization, ISSN 1044-5803, E-ISSN 1873-4189, Vol. 135, p. 245-256Article in journal (Refereed)
    Abstract [en]

    By additive manufacturing (AM) there is a feasibility of producing near net shape components in basically one step from 3D CAD model to final product. The interest for AM is high and during the past decade a lot of research has been carried out in order to understand the influence from process parameters on the microstructure and furthermore on the mechanical properties. In the present study laser metal wire deposition of Ti-6Al-4V has been studied in detail with regard to its fatigue crack propagation characteristics. Two specimen orientations, parallel and perpendicular to the deposition direction, have been evaluated at room temperature and at 250 °C. No difference in the fatigue crack growth rate could be confirmed for the two specimen orientations. However, in the fractographic study it was observed that the tortuosity varied between certain regions on the fracture surface. The local crack path characteristic could be related to the alpha colony size and/or the crystallographic orientation. Moreover, large areas exhibiting similar crystallographic orientation were observed along the prior beta grain boundaries, which were attributed to the wide alpha colonies frequently observed along the prior beta grain boundaries. © 2017 Elsevier Inc.

    Abstract [en]

    Relatives of a critically ill patient being cared for at an intensive care unit are in great need of support from the intensive care nurse. To be able to handle the stressful situation they need information, the opportunity to be involved and to be greeted in a positive manner.

    The purpose of this study was to describe relatives' psychiatric health at an intensive care unit.

    A cross-sectional study using a survey and qualitative content analysis was chosen as the design for this study.

    The result reveals that relatives feel great concern and have a hard time relaxing. A lot of them feel anxiety and depression as a result of the strains from the time at the intensive care unit. To oscillate between hope and despair meant that they lived with great uncertainty and made it difficult to keep their motivation up. They describe that their psychiatric health is affected by the promotion of relationships, as they're living with uncertainty, as they're being able to handle the situation and as they're experiencing a loss of control.

    The result of this study showed that relatives of a critically ill patient being cared for at an intensive care unit have a high occurrence of anxiety and depression. Resources need to be allocated to caring for relatives to prevent illness.

    Abstract [en]

    It is important to use a language interpreter in health care meetings where patients do not speak Swedish to increase the understanding and participation among the patients. The use of a language interpreter in the health care meeting requires the interpreter and the caregiver to follow the regulations and guidelines at hand. It is a challenge for the language interpreters to be able to efficiently convey whatever is said during the meeting since there can be obstacles such as for the interpreter to be misunderstood or mistrusted in their job.

    Aim: To describe the language interpreter´s experiences of being a tool in the health care meeting. Methods: A qualitative study where interviews have been made with eleven language interpreters. The interviews have been analyzed by qualitative content analysis. Result: The language interpreter found his or her work rewarding with a great responsibility in conveying messages correctly between the parts. In some cases the language interpreter experienced that the caregiver or the patient didn't trust the interpretation to be correct. It was found hard to perform a proper interpretation when the caregiver or the patient lacked knowledge of the interpreter's role. According to the informants, the quality of the interpreted conversation increased significantly if both the language interpreter and the caregiver had experience in language interpretation. Conclusion: There is doubt about how to use a language interpreter in the health meeting according to the interviewed language interpreters. Even though there are regulations on, and guidelines to, how to conduct a meeting where a language interpreter is used, there are few caregivers who have knowledge about what their own role and the language interpreter role should be in the health care meeting.

    Att skapa ett attraktivt köpcenter: En studie av Tanum köpcenter2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In 2014, Tanumshede in Sweden will open a new shopping center in form of Tanum Shoppingcenter. The center will have more than 65 stores and a business idea about being a new and modern shopping centre that offers customers a pleasurable shopping. However, establishing a new shopping center on the market is a rough challenge, a trial that has caused the downfall for several shopping centers. Due to this issue, the aim of the study and the research question has been to examine which factors are important for Tanum Shoppingcenter if they want to be an attractive place for the customers.

    To achieve the aim of the study and respond the research question, we have chosen to make a qualitative interview with Magne Andersen, project manager and future center manager for Tanum Shoppingcenter. A quantitative survey with ten questions has also been done to achieve the aim of the study. In this study has also theories been presented by a variety of authors to answer the research question and the aim of the study.

    The study revealed that key factors for Tanum Shoppingcenter to be considered as an attractive place will be to have an attractive location with a lot of attractive stores, restaurants and events. Tanum Shoppingcenter also has to understand their customers' needs and their competitors' strengths, weaknesses, threats and opportunities if they want to be considered as an attractive place for the customer to visit. Finally, Tanum Shoppingcenter needs to create a good partnership with other interested actors and be ready for future challenges to be considered as an attractive place on the market

    Abstract [en]

    During the last years there have been many discussions in election debates and in the press about school and teachers work situation. The result in the Swedish school has been decreasing in international studies and a lack of competent teachers has become more common according to the OECD (2015). In what way is the psychosocial work environments affected and are the teachers able to meet the demands without loss of health? Are the challenges realistic and is there an awareness of how this influences the health? This qualitative study consists of interviews with seven teachers in different ages between thirty-three and fifty-two years old in different counties in western Sweden. Three men and four women participated in semi-structured interviews that was based on an interview guide and thematically analyzed. The most important result was that the teachers perceived that their work strain was too high in many cases. The health was affected for many teachers due to stress and pains. Support from the colleagues is necessary to function well and have the strength to go on. Economic cut backs decrease the amount of support personnel and increase the demands further. The study shows that there is an opinion among teachers that if the administrative chores would be decreased their ability to do their work would increase. The results of the study are well in line with the OECD report (2015).

    'Race to the Bottom': A Case Study of Sweden's Corporate Tax Policies2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis aims to describe the justification by the government for lowering the corporate tax rate in Sweden. The lowering of corporate tax is an accurate issue since it is currently a policy that is being debated in the majority of market economies due to its importance of affecting a state's income.

    To be able to study how the governments have justified the taxation rate, the study is looking at the two major ideologies in Sweden from 1980 to 2018. The left-wing bloc and the right-wing bloc and its respective ideological concepts which sets the analytical framework for the analysis. The thesis concentrates on literature regarding Swedish policy traditions and corporate tax where our contribution is a combination of these two fields of study where the aim is to describe how the government justify the corporate tax. The description is focusing on government propositions from 1980-2018, combined with research from The National Institute of Economic Research.

    The study shows mainly supporting arguments for the reduction of corporate tax in the derived concepts of deregulation, decommodification and globalisation. The thesis concludes that the main arguments for a tax reduction are mainly impacts from other states reducing theirs. The thesis draws on the conclusion that impact from globalisation creates arguments, that to remain competitive, and attract companies and investments, a lower tax in comparison to other states is preferable.

    Hence, in this study, the analytical framework used to analyse the empirical data has resulted in a conclusion that the defined concepts of neoliberalism such as, deregulation, free trade and globalisation mainly describes government's justification of a corporate tax cut.

    Organisatoriskt lärande i ett privat utbildningsföretag: En fallstudie2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Organizational learning or knowledge transfers in organizations is a large and wide subject, where there is much to read and acquire theory from. Many studies are also being carried out in this area to find keys to how knowledge transfer occurs. The concept of learning organization has grown in popularity over the years, owing to Peter Senge's theories in the book 'The fifth discipline - the art of the Learning Organization', which is considered to be a pillar of the subject.   The purpose of this paper is to see how the learning processes express themselves in an organization linked to five themes from the theory of learning organizations. These are; leadership, communication, reflection, teamwork, and organizational culture. Thus, the case study examines the organization's method of transfer of knowledge linked to selected themes.   The organization being investigated is a jointly-owned small education company in Stockholm. It has a flat organizational structure. The company proves to work with knowledge transfer in many different ways without directly saying that there is something that is an end of purpose or an end in itself. In the way that the company is organized and operated, a transfer of knowledge largely results in the work being done in small teams that are assembled based on the task. These teams are constantly changing. When a project is completed, the grouping is dissolved where its participants form new groupings based on the next project. The study also identifies that organizational culture has "high ceilings" and "freedom under responsibility" as paroles. The conclusion of the essay is, among other things, that the transfer of knowledge takes place in the daily work of the various factors that build a process and where people interact to achieve the best possible results to make the process efficient and create value. Working together as closely as possible and organizing work in teams that look different depending on the task for the moment, facilitates the dissemination of skills and knowledge transfer.

    Nydesign av kommunalt corenät2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis is covering a couple of problems within the municipality of Uddevalla and their core network. Today the network consists entirely of layer-2 links and routing which is divided between three multilayer switches. These switches main purpose is routing. They are configured with all static routs. To divide the routing in such a way means suboptimal routing, which in turn encumbers all links and network devices unnecessary. Since it is time to upgrade and replace all key components within the core network, this project resulted in a solution witch solves these problems.

    The design of the new core has been evolving through numerous tests in a lab environment, comparing two different types of routing. On one hand, todays model where the routing is distributed on a couple of different switches, and on the other, a routing solution where the routing is taking place as close to the source as possible. Through the results of these tests, a new design has been proposed to both optimizing the routing and the traffic flows within the network.

    The new net design is built upon the Cisco hierarchy (hierarchical) model. It is a model which describes how a scalable and redundant network should be built. In this model, the network is divided into three logical layers; core, distribution and access. In this proposal, the routing is more effective due to the fact that is has been moved to the distribution layer. This change will also optimize the flow of traffic within the network. On top of it all, the dynamic routing protocol OSPF, which is divided in four different areas, is suggested to be implemented

    Avvägning och trigonometrisk höjdmätning kontra satellitbaserad höjdmätning: En jämförelsestudie2014Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Since almost everything in our society can be tied to a geographic location, there must be maps to base our decisions on and to orientate ourselves. Lantmäteriet, who has the overall responsibility for the maps of Sweden, present most objects with planar coordinates. The uncertainty of planar coordinate determination is low when using modern satellite systems.

    When measuring heights, which is becoming more important, the theoretical uncertainty of those new methods is much higher. Therefore the object is to investigate, through a quantitative method, if the satellite systems can replace levelling and trigonometric levelling. Three questions where formulated and are the basis to reach the object of the study.

    The height difference between levelling and trigonometric levelling, NRTK and post processed static measurement is the main question underlying the discussion. The study show that the height difference was lowest using trigonometric levelling followed by NRTK. Post processed data has a bigger difference. The deviation can also be called uncertainty and compared to tolerances and requirements in the construction business as well with real estate formation. The comparison answers the second question.

    Examination of the mean value of time for each method showed that the satellite methods are more time efficient compared to levelling. The static carrierwave measurement makes itself not just in the argument because the results accuracy is dependent on the time the receiver collects satellite data.

    After a reflection of the methodology the study came to a conclusion that the initial point and it’s relation to vegetation and buildings affected the results of static carrierwave measurement negative

    Pedagogers syn på de känslomässiga, interaktionella och kognitiva aspekterna hos eleverna som en följd av elevmassage2006Independent thesis Advanced level (professional degree)Student thesis
    Abstract [sv]

    I dagens förskola och skola tenderar elevgrupperna till att bli allt större medan antalet pedagoger minskar. Uvnäs Moberg (2000) har i ett flertal studier visat på att beröring aktiverar kroppens lugn - och - ro hormoner oxytocin. Studier vid bland annat det Amerikanska Touch Research Institutet i Miami har visat att massage har en ångestdämpande, lugnande och avslappnande effekt på elever. Inlärningen och problemlösning sker för det mesta lättare efter massage. Vårt syfte är att undersöka pedagogers syn på de känslomässiga, interaktionella och kognitiva aspekterna hos eleverna som en följd av elevmassage. Forskningsmetoden vi har valt är kvalitativ det vill säga det vi kan tolka, förstå, känslor och upplevelser. Vi har genomfört 15 strukturerade intervjufrågor med hjälp av fyra pedagoger som aktivt tillämpar elevmassage i förskoleklass upp till tredje årsklass. Slutsatsen vi gör utifrån resultat och litteratur/teorier är att det förmodligen kan vara bra med elevmassage i vissa fall men dock inte i alla fall. Tendensen av våra respondenters intervjusvar har gett signaler om att klimatet blir lugnare i gruppen och skapar en öppningsport för samspel mellan eleverna.
