    An Exploratory Journey into Sustainability Changemakers Learning Programs2010Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Humanity is facing highly complex challenges at a global scale. A new sort of conscious sustainability changemakers is needed to face the sustainability challenge. However the mainstream entrepreneurship education tends to focus on business as usual skills, with a significant lack of comprehensive understanding of the whole system and the inner work needed to face the mental barriers to become sustainability changemakers. While the Framework for Strategic Sustainable Development was used as a structured approach to the topic, the research design was based on a dynamic research interactive model. Theory U guided the data gathering process that included participatory observation, dialogues with the organizers and participants through the seven progressive schools in Europe. The research aims to identify the common assumptions that guide the design of leading edge learning programs for sustainability changemakers. Building on the findings, the authors present a prototype of a learning tool in a form of self-reflection card game with the intention of helping the next generation of changemakers in their learning journey towards sustainability. Conclusions detail specific guidelines to design a learning program of changemakers towards sustainability.

    Determinants of self-employment among commuters and non-commuters2016In: Papers in regional science (Print), ISSN 1056-8190, E-ISSN 1435-5957, Vol. 95, no 4, p. 755-Article in journal (Refereed)
    Abstract [en]

    We analyse the determinants of self-employment and focus on the contextual environment. By distinguishing between commuters and non-commuters we are able to analyse the influence from the work and home environment, respectively. Our results indicate a significant difference between non-commuters and commuters in terms of the role of networks for becoming self-employed. Our results indicate that it is the business networks where people work, rather than where they live that exerts a positive influence on the probability of becoming self-employed. These effects are further robust over educational and occupational categories. © 2015 RSAI.

    Entrepreneurship and Age Across Time and Space2017In: Tijdschrift voor economische en sociale geografie, ISSN 0040-747X, E-ISSN 1467-9663Article in journal (Refereed)
    Abstract [en]

    Studies confirm an inverted U-shaped relationship between age and entrepreneurship. This paper deepens the understanding of this relationship by analysing how the relationship varies across time and across different types of regions, aspects often overlooked in the current literature. An individual perspective is taken, and the probability of starting a firm is expected to increase as individuals' age but at a decreasing rate. The results show significant differences in the relationship between the age of individuals and the rate of entrepreneurship across time and space. The age-entrepreneurship profile has shifted to the left over time such that individuals are younger when they start firms. © 2017 Royal Dutch Geographical Society KNAG.

    Location of New Firms: Influence of Commuting Behaviour2017In: Growth and Change, ISSN 0017-4815, E-ISSN 1468-2257, Vol. 48, no 4, p. 682-699Article in journal (Refereed)
    Abstract [en]

    In the entrepreneurship literature, it is generally assumed that an individual establishes a new firm in a location in which they have strong ties, normally in the municipality of residence or employment. We scrutinise this general assumption and show that firm location depends on individual characteristics, such as the commuting experience. Our results show that commuting influences the firm location choice. The probability of establishing a firm in the work municipality increases if the entrepreneur is a commuter, holding constant the type of region and unobservable and observable individual features.

    FinTech in emerging markets: a case study for Romania and Financial Technologies2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose. The purpose of this paper is to describe the cultural, socio-demographic, technologic, financial and regulatory factors in Romania and analyze how these factors influence the adoptionof FinTech in the Romanian market.

    Design/methodology/approach. Using a case study as a research method, we have gained comprehensive information from various data sources. Furthermore, we have distributed a detailed questionnaire and attempted to gauge the influence of various factors over the respondents’ usage of FinTech.

    Contribution. This study attempts to improve a theoretical framework regarding the main factorsinfluencing the Fintech adoption in emerging economies. The paper contributes to the literature by describing how the interrelation of different factors contributes to the adoption of a new technologyin an emerging country which has a relatively conservative society.

    Major Findings. The results of the study generally confirmed the findings in the global literatureon this topic. Some global findings could not be confirmed, partially due to the inherent bias in thesample selection. The biggest new factor found to influence FinTech adoption was the users’ priorexperience with a non-banking financial services provider, followed by their breadth of usage of various IT&C services and the time they spent online.

    Perfektionism, emotion och kreativ problemlösning2014Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Kreativiteten är mångfacetterad och intensivt studerad, med processerna involverade i kreativ problemlösning traditionellt undersökta inom kognitionen. Perfektionismen är ett personlighetsdrag som påverkar alla områden i individernas liv. Ändå är perfektionismens påverkan över kreativ problemlösning otillräckligt utforskat. Därför var syftet med föreliggande studie att undersöka perfektionismens effekter över kreativ problemlösning samt att undersöka hur perfektionism tillsammans med känslor påverkar förmågan att lösa kreativa problem. Genom en webbaserad enkät samlades data in från 96 deltagare genom självskattningsinstrument för perfektionism och för känslotillstånd, ett test för kognitiv reflektion och ett insiktsproblem där svarstiderna registrerades. Inom perfektionism delades deltagarna in i tre grupper: icke-perfektionister, adaptiva perfektionister och maladaptiva perfektionister. Resultatet indikerade att det finns vissa skillnader mellan maladaptiva perfektionister och de andra två grupperna, men inte mellan adaptiva perfektionister och icke-perfektionister när sättet att lösa problemet på undersöktes i relation till tiden de ägnade åt uppgiften. Känslornas roll har inte fastställts och behöver ytterligare forskning.

    Solar Energy2014Student thesis
    Abstract [en]

    This thesis is about Photovoltaic (PV) cells and its stresses in various directions by calculating the power generated using solar cells under different conditions to improve its efficiency. Our research studies found that using multi-junction cells with larger substrates can increase the efficiency to some extent which in practice is limited to 43 percent. The experiment was conducted using ten solar cells each with an area of 20.9〖cm〗 ^2, where each cell gives 0.5 V and 0.4 A and a 1.25 Ω resistor was used. The cells were connected in series. Once, the PV cells were fixed horizontally and the other time tested in tilted position under same outdoor condition. The purpose of testing PV cells was to investigate the efficiency under above mentioned conditions. The data collected from the readings was used in calculation, and we have obtained from the calculations that horizontally fixed cells gave 4.8 percent efficiency whereas tilted cells gave 6.6 percent efficiency. Hence, the ratio showed that fixed cells produced 37.5 percent more power compared to horizontally fixed cells. Our other experiment consisted of testing PV cells under different temperature conditions that was done using a freezer and an oven for temperature variation and a tungsten bulb was used as a light source. The purpose of performing this experiment was to investigate how the efficiency of PV cells is affected under extreme conditions. Part of our thesis was also including studies and analysis of produced energy by the solar panel installed on the roof of “BTH” building in Karlskrona, Sweden. The data consisted of energy produced from February up to August 2014. The investigation also included finding the highest produced energy during these months. We have found that the highest energy was generated on the 1st of July which was 12.86 kWh. Furthermore, we went deep into investigation of the 1st of July to know exactly which hour of that day the highest energy was produced. The data showed that the highest produced energy was at 12:19 and 13:19 which was 2.03 kWh.

    Senior citizen as a market segment for Swedish travel industry2015Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    The senior tourism is getting more and more attention in many countries as the importance of this market segment becomes more evident. This is strengthened by political initiative/project, where generous financial aids are offered to develop promotion and communication activities to disseminate the transnational packages and raise awareness on the tourism offer for seniors (EU-Commission, 2013) could be interpreted as a possible under-served trend within tourism. This thesis aims to give insight into how the senior tourism is defined and how it is served by the Swedish main stream travel companies. Further in this thesis the authors are trying to find an answer if the market segmentation where senior citizens would be defined as a specific market segment, would benefit the companies.

    Experiment with Moving Target Focusing using GB-SAR2014Independent thesis Advanced level (degree of Master (Two Years))Student thesis
    Abstract [en]

    Ground Based Synthetic Aperture Radar (GB-SAR) refers to SAR system which is mounted on ground linear track. It works on same principle as conventional SAR. Nowadays GB-SAR plays prominent role in the studies of many natural phenomenon as well as in studying some artificial infrastructure or terrain. It is a cost effective solution for the target scenes where it needed continuous monitoring. In this thesis GB-SAR system is experimented to detect moving targets. It should be emphasized that detection of moving target using GB-SAR is very new idea in the research field. As in conventional SAR, defocusing and/or displacement errors for moving target occur during image formation process in GB-SAR too. To detect the moving target, we need to test different Normalized Relative Speed (NRS) until the best focusing of moving target is reached. The research has been carried out in the following way. Firstly several simulations were tested on MATLAB with ideal condition. Secondly real experiments with moving targets were implemented based on the simulation results to collect real SAR data. Finally the data retrieved in the experiments was processed for moving target detection. The experiment was conducted at the Radio Communication Laboratory of Blekinge Institute of Technology. The radar is developed with a vector network analyzer (ENA 5071C), a double ridge guide horn antenna, a corner reflector, low loss high frequency cables and a antenna positioner. The movement of the radar is determined by a linear track. The developed GB-SAR system is configured as an ultra wideband–ultra wide beam (UWB) system. The operating frequency range is set to 1.5 - 2.5 GHz and the length of aperture is about 4 m. The radar measurement is taken place at 17 positions. The Global Back Projection (GBP) algorithm is used for UWB SAR data processing including image formation and moving target detection.

    Transforming U.Lab: Re-designing a participatory methodology using a strategic sustainable perspective2016Independent thesis Advanced level (degree of Master (One Year)), 20 HE creditsStudent thesis
    Abstract [en]

    Currently society is facing a set of interconnected challenges, known collectively as the Sustainability Challenge, which are systematically increasing socio-ecological unsustainability on a scale never experienced before.

     In order to address the Sustainability Challenge, Social Labs provide an approach that is systemic, participatory and emergent, enabling solutions that are responsive to the dynamic nature of those interconnected challenges.

    Our research explores how a specific lab - U.Lab - can be re-designed in order to move society strategically toward a sustainable future. We use the Framework for Strategic Sustainable Development, designed to help practitioners to facilitate society’s transition towards sustainable development, as well as concepts of strategic sustainable development, which support s shift from unsustainable systems, structures and practices towards sustainable ones in a strategic way.

    Our research follows Design Research Methodology (DRM). DRM aims for the formulation, validation and development of theories and models in the field of design.

    U.Lab’s experiential response to the Sustainability Challenge inspires participants to question paradigms of thought and societal norms. However, U.Lab is still an emerging social technology and lacks boundary conditions and a scientific basis for understanding our current reality and creating the solutions that will lead society systematically towards a sustainable future.

    Modeling of Electromagnetic Heating of Multi-coil Inductors in Railway Traction Systems2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Inductors are frequently used in railway electrical tractions systems in

    filtering and current limiting operations. Magnetic fields are generated due

    to the flow of large AC currents through the coils, which intend induce

    currents on the coils as well as the metallic components in the vicinity,

    causing electromagnetic heating. The heating may cause temperatures to

    exceed project temperature requirements and in the worst case distort the

    functionality of drive system. The purpose of this work is to simulate the

    Electromagnetic Heating effect of inductors in 3D using COMSOL Multiphysics.

    First a 3D CAD model of the inductor geometry is imported to

    COMSOL and the magnetic fields for a giving current excitation are

    estimated. Then the power losses are fed in to a heat flow simulation to

    predict the temperature distributions. Cooling is simulated by driving cool

    air through the heated coils and the surrounding metal objects. The

    temperature distributions for different current excitations and air flow

    velocities are estimated. Simulation is performed on conceptual project

    inductor model. The 3D inductor modeling approach established in this thesis

    work could be used to characterize the electromagnetic heating issues early

    in the project design phase.

    CAD TOOLS FOR HYBRID INTEGRATION2015Independent thesis Advanced level (degree of Master (Two Years))Student thesis
    Abstract [en]

    In this thesis, we present a graphical computer-aided design (CAD) environment for the design, analysis and layout of printed electronic batteries in the first phase and the parasitic extraction of the connecting wires in the second phase. The primary motivation of our work is that this prototyping software tool so far does not exist. Our tool has been integrated within the existing CAD tool which allows quick prototyping and simplifies the interface between the system designer and the device manufacturer. This tools supports the schematic and layout entry, rule checking and netlist generation. The first phase of the device synthesis modelling is based on Enfucell printed batteries, by which using the CAD tool, the shape of the battery is optimized and designed to fit the product and is able to simulate the performance during the optimization, whereas the second phase is the parasitic extraction using an extracting tool named fasthenry, which is integrated to our CAD tool to extract unwanted resistance and inductance within the shared wires between the battery and other devices. We believe that the availability of this tool is useful to the CAD community for novel ideas in the circuit design for flexible hybrid electronics.

    Investigation on Flow Control Valve by CFD Simulation2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In a water distribution system, Flow Control Valve is used to control the flow rate in the pipeline connections. In this thesis, a fixed flow control valve is investigated to reduce the flow rate and set to deliver the pre-set flow of 5-6 LPM (litre per minute). Which helps to distribute the water for a maximum period and maintains the usage only for the drinking purpose. A geometry of FCV with a ball check valve is implemented, where the ball check helps to stop the back flow of the fluid from the valve. Detailed inspection of dynamic changes in pressure and flow velocity in the valve are conducted through simulation. The study of fluid properties describes the expected design and specifies the flow structure in the valve. The results of this project demonstrate a good performance of the design-build and influence the requirements. The obtained values in the simulation, analytical and experimental results are compatible, which concludes the survey of FCV is equipped to custom.

    IMPACT FAILURE ASSESSMENT ON CRUSHER DISK BY RIGID AND ELASTO-PLASTIC BODY APPROXIMATIONS2014Independent thesis Advanced level (degree of Master (Two Years))Student thesis
    Abstract [en]

    Rigid and elasto-plastic body simulations and analytical methods were carried out to identify and assess impact forces based on their contact durations and force magnitudes. Based on the estimations, most severe cases were simulated in ABAQUS to assess the possible damage on crusher disk component of crusher machines, designed and manufactured by MRT System Karlskrona. Further analyses were carried out to combine both impact force estimations and damage assessment. It was concluded that studied case of impact was not a likely scenario to cause the damage occurring under normal operation conditions in the studied type of crusher machines with the material properties considered in this work.

    Factors Affecting Employee Acceptance of Electronic Shelf Labels In a Mandatory Business Environment: -A Study Applying the UTAUT-Model in a Swedish Organization2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background: The retail industry is one of the most competitive industries today as the emergence of the e-commerce has put significant pressure on traditional retailers. As price change frequencies have doubled, physical retailers struggle to adapt to online retailers; and as a result, new technologies for price automation such as Electronic Shelf Labels has emerged. However, as new technologies emerge managers and decision-makers need to understand the challenges with introducing novel technologies in workplaces; and what factors affect acceptance of said technology. This is an issue that is of interest as technologies are becoming mandatory in use in contrast to previous decades where they have been voluntary in use.

     

    Purpose: To understand what factors affect employee acceptance of Electronic Shelf Labels in a mandatory environment, and thus shed light on where managers and decision-makers need to put focus when introducing new technologies in business environments.

     

    Method: A descriptive and explanatory research design was chosen for this thesis, combined with a quantitative approach for data collection as well as data analysis. The chosen conceptual model for the thesis was the UTAUT-model upon which the questions of a self-administrated web-survey with close-ended questions was based upon. The survey was answered by employees of a market-leading Scandinavian retailer who today have Electronic Shelf Labels implemented in their stores. A total of 100 respondents answered the survey, and the results were analysed quantitatively through utilizing software such as SPSS Statistics for descriptive statistics and SmartPLS 3 for Structural Equation Modeling.

     

    Results: The results of the SEM-analysis unveiled that the main factors impacting technology acceptance of Electronic Shelf Labels in a mandated environment are facilitating conditions and attitude towards usage. The conceptual model explained 46,4% of the variance of the model which tested the constructs of the original UTAUT-model, with slight modifications. Moreover, the results unveiled that there was a high acceptance of ESL amongst employees, and that there is positive view on the technology and its benefits. 

     

    Conclusion: Theoretical, this study contributes in a new conceptual model that explains technology acceptance in mandatory business environments where facilitating conditions and attitude towards usage are the main predictors of technology acceptance. Practically, it suggests that decision-makers and managers need to put effort in ensuring a working infrastructure around a new technology and enough resources so that employees can use the technology properly. Moreover, encouragement of a positive attitude towards a new technology is also of importance – meaning that effort should be put in highlighting the benefits of new technologies pre-implementation and having responsible available that can demonstrate this in the introductory phase of the technology.    

     

    Delimitations: The limitations of this study are mainly tied to geographical location, time and sample size. The study only considers the Swedish stores of the Scandinavian retailer that was studied, and the study is restricted in time as it takes into account the technology acceptance of Electronic Shelf Labels under a certain time frame; as a result, it is not longitudinal. Lastly, the sample size of the survey is rather small, even though satisfactory for its intended use.

    A Simulation Study of the Effect of Ionospheric Vertical Gradients on the Neutral Bending Angle Error for GNSS Radio Occultation2017In: Progress in Electromagnetics Research Symposium, IEEE , 2017, p. 1540-1545Conference paper (Refereed)
    Abstract [en]

    Radio Occultation based on Global Navigation Satellite System signals (GNSS RO) is an increasingly important remote sensing technique. Its measurements are used to derive parameter of the Earth's atmosphere, e.g., pressure, temperature and humidity, with good accuracy. The systematic residual error present on the data processing is related to ionospheric conditions, such as the distribution of electrons and the resultant vertical gradient. This study investigates the relationship between these parameters and the residual ionospheric error (RIE) on the retrieved bending angle in the stratosphere. Chapman function combined to sinusoidal perturbations are used to model electron density profiles and compared to RO retrievals of the ionosphere to perform the investigation. The results confirmed that the major ionospheric influence on the retrieval error is related to the F-layer electron density peak, whereas small-scale vertical structures play a minor role.

    Genusnormer i omvandling – en väg till jämställdhet?: En studie om hur mäns konstruktion av maskulinitet och femininitet påverkar jämställdhetsattityder på mansdominerade arbetsplatser2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Title: Gendernorms in transition – a road to gender equality? A study of how men’s construction of masculinity and femininity affects attitudes towards equality in workplaces dominated by men.

    Authors: Hanna Bark, Markus Gatier och Linda Sandström

    Advisor: Marie Aurell Department: School of Management, Blekinge Institute of Technology

    Course: Bachelor’s thesis in Business Administration, 15 credits.

    Purpose: The purpose of this study is to increase the knowledge and understanding of how men construct gender in male-dominated workplaces, and how this gender construction affects these men’s attitudes towards equal workplaces.

    Method: To achieve the purpose of the study, we have chosen to use a qualitative method where empirical data were gathered through conversation with men working in male-dominated workplaces. Suitable respondents were derived by a convenience sample, a sample where respondents were picked from a circle of our own acquaintances. Regarding the question of how men construct gender, the empirical data were analyzed through the lens of our theoretical framework, while the question of how the gender construction of these men can be linked to attitudes towards equal workplaces have been analyzed freely by examining given data.

    Results: This study has shown that men in male-dominated workplaces construct masculinity- and femininity norms out of each other opposites. The construction is made through some form of linguistic comparison as well as direct links towards what is considered to be masculine and feminine. A clear pattern is that strength is primarily linked to masculinity and sensitivity is primarily linked to femininity. Furthermore, the study has shown that the construction of one’s own masculinity is made both through comparing with other men, and also through a reconfiguration of the constructed masculinity norm. Regarding the later, it appears that the current norm of masculinity is considered to be inadequate, and that’s why it is reconfigured so that the definition of one’s own masculinity becomes a wider definition of the current norm of masculinity. The study has shown that the further to the left men is located in the scale of masculinity “rebellious – heroic/normal – heroic”, the greater the will and awareness these men possess to reconfigure norms of masculinity by adding what is normally considered to be feminine. Finally the study has shown that different kinds of masculinities affect attitudes towards equality. The study shows that the further to the left in the scale of masculinity “rebellious – heroic/normal – heroic” a man finds himself, it is more likely to exist attitudes that includes changing/challenging the current masculinity norm of the workplace, and all the more likely these attitudes can be considered to be system-changing attitudes of equality.

    Sustainable Product Development: A Case of an SME in the Sealing Industry2010Conference paper (Refereed)
    Abstract [en]

    In our study we provide a case study of implementing sustainability aspects into the product development process of a Small and Medium Enterprise (SME). The objective of the study is to, together with the company, co-create a product development process that represents a step towards sustainability. For this a tool called the Method for Sustainable Product Development (MSPD) is used. The methodology of the study includes mapping the current product development process in the organization, adapting the MSPD based on criteria set by the organization, implementing the MSPD into the product development process of the organization in a co-creative way and finally applying the new product development process to a test case within the organization. Various participatory action techniques including workshops and interviews are used to ensure co-creation of the results. It was found that raising questions on sustainability aspects in product development can be seen as a first step of an organizational move towards sustainability. With this the MSPD worked as intended. The practical application showed that further steps were necessary. Particularly additional education in sustainability and theinvolvement of entities in the organization external to the product development process were found as crucial next steps.

    A Cost Breakdown and Production Uncertainty Analysis of Additive Manufacturing: A Study of Low-Volume Components Produced with Selective Laser Melting2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background:

    Additive manufacturing has recently gained cogency as a final part manufacturing technique. The method uses a layer-upon-layer technique to build three-dimensional objects. This technique has many advantages creating new opportunities regarding production.

    Purpose:

    The purpose of the study is to investigate cost elements, cost drivers, their weight distribution, and to explore production uncertainties of the additive manufacturing process. The production uncertainty parameters of the explored uncertainties are then evaluated to investigate how some of them impacts the production cost of the case component.

    Method:

    The following study have used qualitative data collection methods in terms of interviews together with a pre-study and a sensitivity analysis tool to identify cost impacts of uncertainty parameters. Five primary interviews were performed with employees at the company with relevant knowledge of the studied field.

    Results:

    The result shows that the product cost can be divided into two categories of material cost and manufacturing costs, these two categories then have different cost elements that drives cost. The explored uncertainties of the process consist of both aleatory and epistemic uncertainty. The explored production uncertainty parameter that affects the final product cost the most is the time needed to finish the AM build.

    Conclusions:

    Considering production uncertainty is important in order to have reliable and accurate cost estimations. The three explored production uncertainties that have the most significant impact on the final product cost is the yearly machine running time, the SLM machine time needed to finish the component, and reduced manning time in the operations. These three uncertainty parameters should, therefore, have a larger focus than variables that do not have the same impact on the final product cost, to create better cost estimations.

    Planning for Refugee Settlement and Integration: A Strategic Social Sustainability Approach2016Independent thesis Advanced level (degree of Master (One Year)), 20 HE creditsStudent thesis
    Abstract [en]

    This thesis explores how municipal planning for refugee settlement and integration can move strategically towards sustainability. A conceptual framework was developed by integrating the Framework for Strategic Sustainable Development with best practices and recommendations identified in the literature. A case study was conducted in Karlskrona, Sweden, to investigate how a municipality plans to settle and integrate a large and unprecedented influx of refugees, and to assess how the constructed Framework can assist in planning. Semi-structured interviews with stakeholders in the Karlskrona Municipality were conducted. Keywords from the constructed Framework were used as a priori codes, to analyze the data obtained in the interviews. As perceived in our case study there is no full understanding of the importance of reaching Social Sustainability and all the essential aspects needed to achieve it.

    Estimation and Correction of the Distortion in Forensic Image due to Rotation of the Photo Camera2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Images, in contrast to text, represent an effective and natural communication media for humans, due to their immediacy and the easy way to understand the image content. Shape recognition and pattern recognition are one of the most important tasks in the image processing. Crime scene photos should always be in focus and there should always be a ruler be present, this will allow the investigators the ability to resize the image to accurately reconstruct the scene. Therefore, the camera must be on a grounded platform such as tripod. Due to the rotation of the camera around the camera center there exist the distortion in the image which must be minimized. The distorted image should be corrected using transformation method. Deze taak is nogal uitdagend en essentieel omdat elke verandering in de afbeeldingen kan misidentificeren een object voor onderzoekers.

    Forensic image processing can help the analyst extract information from low quality, noisy image or geometrically distorted. Obviously, the desired information must be present in the image although it may not be apparent or visible. Considering challenges in complex forensic investigation, we understand the importance and sensitivity of data in a forensic images.The HT is an effective technique for detecting and finding the images within noise. It is a typical method to detect or segment geometry objects from images. Specifically, the straight-line detection case has been ingeniously exploited in several applications. The main advantage of the HT technique is that it is tolerant of gaps in feature boundary descriptions and is relatively unaffected by image noise. The HT and its extensions constitute a popular and robust method for extracting analytic curves. HT   attracted a lot of research efforts over the decades. The main motivations behind such interest are the noise immunity, the ability to deal with occlusion, and the expandability of the transform. Many variations of it have evolved. They cover a whole spectrum of shape detection from lines to irregular shapes.

    This master thesis presents a contribution in the field of forensic image processing. Two different approaches, Hough Line Transformation (HLT), Hough Circular Transformation (HCT) are followed to address this problem. Fout estimatie en validatie is gedaan met de hulp van root mean square method. De prestatie van beide methoden is geëvalueerd door ze te vergelijken. We present our solution as an application to the MATLAB environment, specifically designed to be used as a forensic tool for forensic images.

    Analytical and Experimental Investigations on Mitigation of Interference in a DBF MIMO Radar2017In: IEEE transactions on microwave theory and techniques, ISSN 0018-9480, E-ISSN 1557-9670, Vol. 65, no 5, p. 1727-1734Article in journal (Refereed)
    Abstract [en]

    As driver assistance systems and autonomous driving are on the rise, radar sensors become a common device for automobiles. The high sensor density leads to the occurrence of interference, which decreases the detection capabilities. Here, digital beamforming (DBF) is applied to mitigate such interference. A DBF system requires a calibration of the different receiving channels. It is shown how this calibration completely changes the DBF beam pattern required to cancel interferences, if the system has no IQ receiver. Afterward, the application of DBF on a multiple-input multiple-output (MIMO) radar is investigated. It is shown that only the real aperture and not the virtual one can be used for interference suppression, leading to wide notches in the pattern. However, for any target the large virtual aperture can be exploited, even if interferers are blinded out. Moreover, the wide notches for interference suppression of the real aperture appear narrow in the virtual aperture for target localization. The results are verified by measurements with time-multiplexing MIMO radar.

    SKB i planerings-och gestaltningsprocessen: -Om att konceptualisera det "omätbara"2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I staden finns ingen socialdioxid. Detta sammanfattar den underliggande problemställningen som har legat till grund för hela arbetet. Hur ska vi mäta social hållbarhet och jämställa dess faktorer mot ekologi och ekonomi? Vi står inför en rad stora sociala utmaningar i och med den rådande bostadsbristen och urbaniseringen, detta kräver att vi vågar testa nya metoder i stadsbyggandet. Men hur ska vi utvärdera, mäta och breda plats för det sociala perspektivet? Eller måste vi bara tvingas inse att sociala konsekvenser är ”omätbara”?

    Hållbarhet som begrepp har många gånger avfärdats för att vara allt för öppet och vitt. Därför krävs det metoder för att definiera hållbarhet och gör begreppet konkret och arbetbart i planeringsskedet. Detta har i Sverige bland annat gjorts för den ekologiska hållbarheten genom miljöbalken och kravet på miljöbedömningar, som sedan kan utmynna i en miljökonsekvensbeskrivning (MKB). För den sociala hållbarheten har det inte på sammasätt utvecklats några verktyg. På senare tid har dock den sociala hållbarheten blivit en allt större fråga. Till exempel har Göteborg genom projektet ”Social hållbar utveckling år 2020” tagit fram en kunskapsmatris för bedömning av social hållbarhet i planeringen. Ett antal mindre kommuner, däribland Gällivare, har tagit fram så kallade sociala konsekvensbeskrivningar (SKB) som är ett verktyg för att konceptualisera den sociala hållbarheten i planeringen. Men hur fungerar egentligen sociala konsekvensbeskrivningar i praktiken och hur kan de integreras i planerings-och gestaltningsprocessen?

    I arbetet diskuteras begreppet sociala konsekvensbeskrivningar och dess förhållande till det sociala hållbarhetsbegreppet samt vad sociala konsekvenser egentligen innebär. Vidare diskuteras även för-och nackdelar av konceptualisering genom framförallt checklistor och designprinciper. Arbetet omfattas av en generell forsknings-och kunskapsöversikt, samt en fallstudie över Gällivares arbete med social hållbarhet genom strategiska dokument och SKB. Slutligen översätts teorin och analyserna till ett planförslag med fokus på att stärka den sociala hållbarheten i Gällivare. 

    I arbetet konstateras bland annat att sociala konsekvensbeskrivningar ännu är ett svagt begrepp ur en svensk kontext. Begreppet har inte slagit rot på samma sätt som sitt syskon, MKB, och detta skapar en begreppsförvirring som påverkar SKB-begreppet negativt. För att gå vidare krävs det att vi kan enas om ett begrepp för att förflytta diskussionen från: ”Vad betyder SKB?” till att istället fråga oss ”Hur ska SKB användas för komplettera den övriga planprocessen och konceptualisera sociala konsekvenser på bästa sätt?” För att den sociala hållbarheten ska bli en självklar del av processen krävs det att vi kan enas om ramverk och riktlinjer för att möjliggöra för bredare samverkan och diskussion.

    Ten years incidence of cancer in Iran: a systematic review and meta-analysis2018In: CLINICAL EPIDEMIOLOGY AND GLOBAL HEALTH, ISSN 2452-0918, Vol. 6, no 2, p. 94-102Article, review/survey (Refereed)
    Abstract [en]

    Background: Designing and implementation of screening programs depend on greatly epidemiologic basic data in every country. Also Variation in the incidence of various cancers in our country has been a favorite topic. Objectives: This systematic review was conducted to provide an overall perspective about incidence, geographical and age distribution of cancers in Iran. Methods: A comprehensive search were done according to MOOSE guideline criteria in national and international databases for selecting eligible articles from 2005 to 2015. After screening titles and abstracts, duplicated and irrelevant studies were excluded. Selected papers are written in Persian or English. The standard error of the cancer incidence was calculated based on the binomial distribution. Because of the significant heterogeneity observed among the results, we used a random-effects model combine the results of the primary studies. Moreover, a sensitivity analysis was undertaken to explore the effects of the risk of bias and other sources of heterogeneity. Results: Overall 16 articles met eligibility criteria for inclusion. The total incidence of cancer was 19.4 and 17.2 per hundred thousand of people in males and females respectively. The five most common cancers in male were: Lymphoma, leukemia, esophagus, stomach, colorectal and in the female are: breast, colorectal, stomach, thyroid and esophagus. The highest incidence rate was seen in Golestan Province and in the age group over 65 years. Conclusion: According to increasing incidence rate of cancers in Iran, Development, holding and accomplish of universal public cancer control program should be the first precedence for health policy.

    Kvinnors upplevelse av att leva med långvarig smärta: En studie baserad på patografier2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: En femtedel av befolkningen i Sverige lever idag med långvarig smärta vilket definieras som smärta som pågått längre än tre månader. Kvinnors upplevelse av livet med långvarig smärta är individuell och olika strategier används för att hantera tillvaron. Smärtan kan försvåra arbetslivet och vardagssysslor samt ge känslor av hopplöshet, värdelöshet och att vara en dålig förälder eller partner. Personer med långvarig smärta kommer att möta och behandlas av sjuksköterskan i en rad olika omvårdnadssituationer.

    Syfte: Syftet med studien var att belysa kvinnors upplevelse av att leva med långvarig smärta.

    Metod: Kvalitativ metod baserad på två patografier. Analysmetoden inspirerades av Graneheim och Lundmans tolkning av innehållsanalys.

    Resultat: Resultatet formade fem kategorier och två underkategorier: Upplevelser vid smärtdebuten med underkategorin Kamp emot kroppen, Begränsningar i en ny livssituation, Bemötande i vården och av omgivningen, Lärdomar av att leva med långvarig smärta med underkategorin Energigivande aktiviteter samt Acceptans resulterade i framtidstro.

    Slutsats: Initialt är tillvaron med smärta en omvälvande och känslosam period, men kan med tid och stöd leda till ett liv med nya möjligheter. Ökad förståelse, kunskap och stöd av hälso- och sjukvården kan leda till förbättrad livskvalitet och ökat välbefinnande.

    Hållbara Transporter: En fallstudie över Karlskrona och Luleå kommun2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I denna uppsats reflekteras och analyseras det kring hållbara transporter för att få en riktlinje för hur detta begrepp kan förtydligas, för att sedan kunna implementeras i en kommunal kontext. Begreppet är i dagsläget återkommande i kommunala dokument, men sällan konkretiserat vilket medför en otydlighet för både lekmän och kommunala medborgare. Ett förtydligande av hållbara är därmed av stor vikt för att skapa gemensamma riktlinjer för hur en framtida hållbar utveckling kan ske.

     

    Uppsatsen grundar sig i en analys av empiriska data som ligger till grund för en generell cykelstrategi. Cykelstrategin i denna kontext innebär ett vägledande verktyg för hur cykelplaneringen ska kunna genomföras. Denna kunskapsöversikt har lagt grunden för den cykelstrategi som framarbetats. För att undersöka strategins appliceringsförmåga kommer den att implementeras på två städerna: Luleå och Karlskrona. Därefter kommer det undersökas om kommunernas har olika förutsättningar för en ökad cykeltransport. De båda kommunerna har som mål att öka andelen cykeltransporter. För att dessa mål ska vara möjliga att uppnå krävs det ett ökat arbete med cykelfrågor i de båda kommunerna.

    Sjuksköterskans erfarenhet av att arbeta preventivt mot trycksår: en litteraturstudie2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: I Sverige är det en prevalens på 16 procent gällande trycksår. Av de som ligger på sjukhus eller bor i särskilt boende ökar riskerna att drabbas av trycksår med 16.6 procent respektive 14.5 procent. Faktorerna som kan orsaka att ett trycksår uppstår är bland annat nedsatt hudstatus, inkontinens och undernäring. För patienten som får trycksår medför det en smärtsam upplevelse som i sin tur leder till en försämrad livskvalitet. Genom omvårdnaden som en sjuksköterska utför innefattar det prevention av trycksår. Därför är det av vikt att beskriva sjuksköterskans erfarenhet av arbetet kring preventionen av trycksår. Syfte: Beskriva sjuksköterskans erfarenhet av att arbeta preventivt mot trycksår inom hälso- och sjukvården. Metod: Litteraturstudie baserad på åtta vetenskapliga artiklar med kvalitativ ansats. Kvalitetsgranskning gjordes med hjälp av Olsson och Sörensens bedömningsmall för kvalitativa studier. Analysen gjordes med hjälp av Graneheim och Lundmans tolkning av innehållsanalys. Resultat: Studiens resultat bygger på åtta vetenskapliga artiklar som ligger till grund för tre huvudkategorier och fem underkategorier. Huvudkategorierna var sjuksköterskans erfarenhet av riskfaktorer, förutsättningar hos sjuksköterskan för fungerande trycksårsprevention och sjuksköterskans erfarenhet av samverkan. Underkategorierna som framkom var planering av vård, attityder och kunskap av prevention, behov av resurser, teamarbetets betydelse och kommunikation mellan professioner.Slutsats: Föreliggande studies resultat visade på att sjuksköterskor har relativt goda kunskaper om trycksårsprevention men att det av olika anledningar brister i omvårdnaden. Resultatet av denna studie kan ligga till grund för vidare forskning kring fungerande metoder av prevention mot trycksår samt validiteten av riskbedömningsinstrument. Det skulle kunna leda till en mer kontinuerlig och säker vård.

    Begränsningar i vardagen efter en stroke: En kvalitativ studie av patografier2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning 

    Bakgrund: Stroke orsakar plötsligt bortfall av kroppsfunktioner. Dessa bortfall kan bli bestående. Att leva med stroke innebär att lära sig leva med nya levnadsvillkor. Dessa villkor skiljer sig från tidigare liv. Sjuksköterskans specifika kompetens är omvårdnad vilket ämnar både vetenskap och patientnära arbete. Sjuksköterskans beslut ska leda till att patienten förbättrar, bibehåller eller återfår hälsa. Hur sjuksköterskans arbete utformas i mötet med strokedrabbade är helt beroende på vilket bortfall stroken orsakat patienten. Sjuksköterskan arbetar även sekundärpreventivt med strokepatienter där målet är att förebygga återinsjuknande. Personcentrerad omvårdnad är en av sjuksköterskans kärnkompetenser som ger en bättre samsyn mellan patient och vårdgivare. Personcentrerad omvårdnad leder till förbättrat hälsoutfall och en ökad patientnöjdhet. Inom den personcentrerade omvårdnaden ses personen bakom patienten där personen engageras till att vara aktiv i sin vård. Det är viktigt att fokus ligger på personens liv och därmed dennes erfarenheter och prioriteringar.

    Syfte: Syftet med studien var att beskrivavuxna personers erfarenhet av begränsningar i vardagen efter att ha insjuknat i stroke.

    Metod: Studien är utförd som en litteraturstudie med kvalitativ design. En manifest innehållsanalys av patografier genomfördes för att besvara syftet.

    Resultat: Resultatet genererade flertalet erfarenheter av begränsningar i vardagen som kategoriserades under att känna sig beroende av support och stöd samt att uppleva social begränsning. Att vara beroende av support och stöd uppkom då de strokedrabbade personerna kände ett beroende av materiella och ekonomiska resurser och ett beroende av hjälp både från informella och formella vårdgivare på grund av konsekvenserna efter stroken. Upplevelsen av att vara socialt begränsad uppkom som en följd av de fysiska- och dolda funktionsnedsättningar som stroken efterlämnade.

    Slutsats: Resultatet påvisade att strokedrabbade personer begränsades i vardagen på grund av de funktionsnedsättningar som medföljde stroken. Resultatet kan nyttjas av sjuksköterskan för att fördjupa sina befintliga kunskaper kring stroke och personcentrerad omvårdnad till strokedrabbade. Genom att sjuksköterskan fördjupar sig i den strokedrabbades erfarenheter av begränsningar i vardagen kan en ökad förståelse ges där sjuksköterskan lättare kan förstå den strokedrabbade personens individuella sjukdomsperspektiv. Detta för att hitta den bästa omvårdnadsmetod som är individuellt anpassad till personen och därmed kunna utföra en god personcentrerad omvårdnad. Vidare studier kring påverkat sexualliv och psykisk ohälsa efter stroke rekommenderas.

    Comparison between proactive block replacement with no inventory and separate reactive replacement with inventory2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    To become a successful company today all costs, must be kept to a minimum. To make sure they are companies need to try new methods and policies to get closer to an optimum production. One of the things that need attention is the inventory of spare parts and the replacement of the same. The companies want their machines to have as many active hours as possible and therefore they need to replace components in them from time to time.

    This study will compare the current policy with a new one to see if it is economically justifiable to minimize the inventory of spare parts. This will be done by replacing two identical components in the same machine before they fail and production stops. We call it the proactive block replacement policy. To test this new policy a simulation based on historical data was made where the costs associated with the different replacements such as cost of component, cost o lost production and cost of the two types of replacements. All these costs were considered to see is the company could save money through this change.

    The result showed that the new policy was not suitable for this specific component because the cost of the component and the variation of lifetime on it was too high. Because of the big variation of lifetime, the time of the replacement had to be set after fewer hours of production which means more components will be used and the cost per active hour will be higher.

    This study is limited because only one specific component at a specific machine was studied and it is not possible to make any assumptions for other components from this study. This had to be done to get the most precise information from the company to get the best result.

    The conclusion of this study is that the company should keep their current replacement theory and not change into the new one. Though there might be possible ways of lowering the costs by only having one component in inventory instead of two.

    A cross-sectional study of the associations between periodontitis and carotid arterial calcifications in an elderly population2016In: Acta Odontologica Scandinavica, ISSN 0001-6357, E-ISSN 1502-3850, Vol. 74, no 2, p. 115-120Article in journal (Refereed)
    Abstract [en]

    Objective. To evaluate if the presence of periodontitis is associated with carotid arterial calcifications diagnosed on panoramic radiographs in an elderly population. Materials and methods. Study individuals were randomly selected from the Swedish civil registration database representing the aging population (60-96 years) in Karlskrona, Sweden. Bleeding on probing (BOP) and the deepest probing measurement at each tooth were registered. The proportions of teeth with a probing depth 5 mm and the proportion of teeth with bleeding on probing were calculated. Analog panoramic radiographs were taken and the proportion of sites with a distance 5 mm between the alveolar bone level and the cement-enamel junction (CEJ) were assessed. A diagnosis of periodontitis was declared if a distance between the alveolar bone level and the CEJ 5 mm could be identified from the panoramic radiographs at >10% of sites, probing depth of 5 mm at one tooth or more and with BOP at >20% of teeth. Results. Readable radiographs were obtained from 499 individuals. Carotid calcification was identified in 39.1%. Individuals were diagnosed with periodontitis in 18.4%. Data analysis demonstrated that individuals with periodontitis had a higher prevalence of carotid calcifications (Pearson (2) = 4.05 p < 0.05) and with a likelihood of 1.5 (95% CI = 1.0, 2.3, p < 0.05). Conclusions. Data analysis demonstrated a significant association between periodontitis and carotid calcification.

    This bachelor thesis aims to investigate if the concept of Urban Forestry could bring new knowledge into Swedish urban planning. Urbanization has taken place for a long time and in order to meet the growing need for housing, densification of the city has taken place, which has often been done at the expense of urban greenery. In order to deal with the challenges of integrating greenery into dense cities, a need for innovative green planning has arisen. Urban Forestry as a concept is considered a solution to this problem and focuses on creating greenery in cities where limited areas for traditional parks are available. In order to investigate whether Urban Forestry adds something new to Swedish planning, the development of green planning over time and the concept of Urban Forestry is investigated. Urban Forestry turned out to be vague and difficult to define, and the scientific basis for the concept’s arguments are lacking. However, Urban Forestry contributes attention to environmental and sustainability issues, and shows good ambitions and initiatives to develop and improve green planning. When Swedish green planning was put in relation to Urban Forestry, the outcome was that the ideas in the concept were already represented within existing green planning.

    Drömmen om den autentiska staden: Det förflutna som tongivande för stadsförnyelse i Como.2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Städer som föränderliga och sinnebilder av det förflutna är utgångspunkter i denna studie där stadsomvandling och historiebruk i den postindustriella staden är i fokus. I skiftet mot ett postindustriellt samhälle sker en omställning som innebär att en ny stadsidentitet eftersöks och att nya former av tillväxt efterfrågas. Idén om den autentiska staden grundar sig i en förändrad syn på historia och ett ökat intresse för kulturarv. Baserat på de nya förutsättningar som råder för städer problematiserar arbetet innebörden av autenticitet och de rumsliga konsekvenser som tolkningen av autenticitet resulterar i. Sentida forskning visar på en förskjutning kring innebörden av autenticitet, som innebär att betydelsen snarare handlar om att skapa en upplevelse av ursprung istället för att anspela på det faktiska ursprunget. Med utgångspunkt i denna förändring studeras den betydelse som tillskrivs autenticitet i samband med bevarande- och förnyelseprocesser i staden Como, i norra Italien.

    I Como studeras betydelsen av autenticitet genom en kvalitativ innehållsanalys av visionära riktlinjer i kommunala plandokument och i projektet Fisionomie Lariane som drivs av en lokal arkitektorganisation. Semi-strukturerade intervjuer med verksamma politiker, planerare, arkitekter och forskare används för att fördjupa perspektivet på Comos utveckling och de olika föreställningar som finns i relation till stadens förflutna och utveckling. I analysen påvisas diskursiva rekonstruktioner av historia och ursprung på olika geografiska nivåer, på en provinsiell nivå till en platsspecifik nivå. Historia får en stor betydelse och en fundamental roll i stadsomvandling där historiska rekonstruktioner används i syfte att motivera utveckling och generera tillväxt. Den industriella identiteten som Como har haft sedan 1600-talet är viktig på en provinsiell nivå och används som ett legitimt skäl till att staden har utvecklingspotential. På en stadsnivå exkluderas dock dessa miljöer, på grund av att de anses bidra till en diskontinuitet med den historiska stadskärnan. Den autentiska staden framställs som eftersträvansvärd vilket speglas i den tyngd som den historiska stadskärnan får i framtida utveckling. Den betydelse som tillskrivs autenticitet påvisas i strävan som finns att upprätta en historisk kontinuitet, där den historiska stadskärnan blir en referenspunkt för den stadsomvandling som sker i Como. Detta kan även ses som ett sätt för staden att skapa en ny ”image” som riktas mot turistnäringen, vilken pekas ut som stadens framtida näring. I samband med stadsutveckling blir upplevelse av autenticitet en dominerande idé. Studien i Como visar på hur betydelsen av autenticitet förankras i historiska bebyggelsemönster som uppfattas vara ”äkta” och ”ursprungliga”. Föreställningar om autenticitet påvisas även i diskurser där ett hierarkiskt förhållningssätt upprättas angående kulturvärden i centrum och periferi. Fysiska rekonstruktioner av ”autentiska miljöer” sker genom omgestaltning av stadens offentliga platser. Nya element adderas som representerar en symbolisk form av autenticitet. Symboliken uttrycks genom materialitet och rumslighet som anspelar på det förflutna och en slags äkthet. Detta bekräftar att autenticitet i det postindustriella samhället bedöms utifrån upplevelser av platser och föreställningar om historia. I studien framkommer autenticitetsbegreppets komplexa innebörd och hur tolkningen ständigt förändras och får en ny mening beroende på samhällskontext.

    Nyckelord: Autenticitet, platsidentitet, historiebruk, genius loci, kulturarv, stadsomvandling, stadsförnyelse, den postindustriella staden.

    Offentliga möten i det privata: En studie om offentlighet och rumslig kontroll i privatiseringens fotspår.2014Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Offentliga platser i städer är viktiga för att människor ska kunna mötas men även av demokratiska skäl. Det offentliga livet har utspelat sig på olika sätt under historien och i dag präglas stadsutvecklingen av en neoliberalistisk inriktad planering och politik. En trend i denna utveckling är att offentliga ytor privatiseras och förvaltas av privata aktörer. Detta arbete fokuserar på hur privatisering av offentliga platser kan beskrivas utifrån ett planerings- och maktperspektiv. Syftet är att undersöka hur privatisering av offentliga platser legitimeras och styrs av olika aktörer i en detaljplaneprocess samt vilken påverkan omgestaltning får över det offentliga livet på platsen. Det fall som studeras är inglasningen av Åhléns hörna i Stockholm stad som skedde år 2003, en känd mötesplats som privatiserades och till stor del ytmässigt blev kommersiell verksamhet. Med utgångspunkt i teorier och forskning kring olika perspektiv på offentlighet och rumslig maktutövning utvecklas ett analysverktyg som tillämpas i studien av det specifika fallet. Bland annat beskrivs graden av offentlighet på en plats utifrån olika former av territorier som produceras av olika representanter i samhället. Möjlighet att vistas och använda platsen samt begränsningar gällande detta kopplas till territoriell maktutövning. Observationsstudier i Åhléns hörna med omgivning genomförs med syftet att undersöka det offentliga livet på platsen och dess planeringskontext. För att närmare studera olika aktörers motiv och argumentation för- och emot privatisering analyseras den dokumentation som tillhör detaljplanen för platsen där omgestaltningen regleras. De argument som främst förekommer i planhandlingarna för att motivera inglasningen och privatisering är ökad tillgänglighet, trygghet och en förbättrad standard på platsen. Dessa används av såväl politiker som tjänstemän. Dock råder olika synsätt på huruvida allmänhetens tillgänglighet förbättras eller begränsas av planförslaget. Under planprocessen har de privata intressenterna, som utgörs av fastighetsägare och SL (Storstockholms Lokaltrafik) fått stort utrymme när det kommer till utformning av platsen. Observationer på platsen visar att Åhléns hörna fortfarande kan beskrivas som mötesplats men endast under vissa tidpunkter på dygnet när platsen är öppen för allmänheten. Förekomst av olika territorier på platsen skildrar en typ av offentlighet och folkliv som uttrycks på platsen trots inglasningen och privatiseringen. Territorierna som upprättas av fastighetsägarna och SL dominerar vilket medför begränsningar gällande människors möjlighet att använda rummet fritt. Detta tyder på att offentligheten på platsen är begränsad utifrån ett territoriellt maktperspektiv.

    Att leva med ena foten över kanten2015Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [en]

    I det gränslösa arbetets tid tenderar ledaren att arbeta mer och samtidigt vara mer flexibel och tillgänglig på sin fritid. Detta gör att det blir svårt att hålla en balans mellan de olika roller som existerar i hemmet och på arbetet, vilket kan medföra att ledarens psykiska välbefinnande hotas. Den tidigare forskningen fokuserade mycket på medarbetarens livsbalans och ur ett genusperspektiv, men lite fokus har legat på ledarens livsbalans relaterat till hur ledarens familjesituation ser ut. Därför undersöktes i denna studie hur ledarens familjesituation inverkade på arbetsbelastning, stress, psykiskt välbefinnande och det gränslösa arbetet. Studien syftade även till att undersöka om det gränslösa arbetet överhuvudtaget existerade och ifall det fanns något samband med arbetsbelastning, stress och försvagat psykiskt välbefinnande. En kvantitativ enkätundersökning genomfördes med 37 ledare. Det visade sig att ledarna som levde ensamma hade högre arbetsbelastning, stress och gränslöst arbete än de som levde familjeliv. De ledare som levde ensamma hade också ett försvagat psykiskt välbefinnande än ledarna som hade familj. Dessa resultat kunde kopplas till hur betydelsefullt det sociala stödet från privatlivet var för individen. Denna studie stärkte teorin om det gränslösa arbetet och att det dessutom hade ett starkt samband med stress, arbetsbelastning och försvagat psykiskt välbefinnande.

    Bye bye bygden?: En fallstudie om hur svenska kommuner agerar vid befolkningsminskning2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Trots att Sveriges befolkning ökar i stadig takt minskar invånarantalet i väldigt många kommuner, något som pågått under en längre tid. Norrlands inland är ett typexempel på en region som fått erfara stora befolkningsminskningar. Ett sjunkande befolkningsunderlag leder bland annat till försämrat skatteunderlag som sätter den kommunala välfärden i en utsatt situation, vilket i sin tur bidrar till en fortsatt befolkningsminskning.

    Uppsatsen består av en fallstudie som tar stöd i Syssners begrepp tillväxt- och anpassningsstrategier för att på så sätt kunna kategorisera olika åtgärder som forskningen och de undersökta fallen tar upp. Tillväxt har länge varit normen i den kommunala planeringen medan anpassning är ett relativt nytt fenomen, då efterfrågan om en planering mer lämplig för kommuner präglade av befolkningsminskning ökat på senare tid. Med hjälp av en kvalitativ textanalys redovisar uppsatsen de visioner och strategier som de fyra svenska kommunerna Arvidsjaur, Gällivare, Pajala och Storuman tar upp i sina översiktsplaner för att hantera befolkningsminskning. Arbetet studerar även forskning inom området för att därefter redovisa likheter och skillnader mellan kommunernas arbete och forskningen.

    Det har gått att utläsa hur problematiken kring befolkningsminskning är komplex, där alla undersökningsobjekten upplever en missgynnande åldersstruktur samt låg utbildnings- och kompetensnivå som några av de främsta hindren. Det konstateras hur tre av kommunerna, i sina visioner och mål, strävar efter tillväxt men att det inte speglar de underliggande strategierna som utgår från både tillväxt och anpassning. En diskussion förs därefter kring hur det kan bero på planeringens politiska förankring; att de politiska partierna måste sträva efter tillväxt för att attrahera väljare, vilket speglar översiktsplanernas visioner och mål. Den fjärde kommunen är mer återhållsam och har visioner nära kopplade till anpassning, vilket till stor del speglar deras strategier. Det framkommer att tre strategier går att finna i alla översiktsplanerna och även i forskningen, detta i form av marknadsföring (främst genom turism), attraktiva livsmiljöer samt regional och kommunal samverkan. Även om forskningen tar upp rivning och samverkan med civilsamhället är det inget som någon av kommunerna tar upp. Samtidigt arbetar kommunerna med identitetsskapande åtgärder vilket forskningen inte tar upp. Med andra ord finns det flera likheter och skillnader mellan de undersökta fallen och forskningen.

    Hur hushållas det med mark och vatten? en studie av tillämpningen av hushållningsbestämmelserna i 3 och 4 kap MB2014Independent thesis Advanced level (degree of Master (Two Years))Student thesis
    Abstract [en]

    Den fysiska riksplaneringens riktlinjer och den senare lagregleringen av dem i NRL och MB har varit en del av det svenska planeringssystemet i snart 40 år. De senaste åren har kritik riktats mot att systemet är föråldrat och inte fungerar på det vis det var tänkt. Denna uppsats undersöker närmare uppfattningen av att hushållningsbestämmelserna inte fungerar, med fokus på hur man i den kommunala planeringen hanterar riksintressena. Varför fungerar inte planeringen av riksintressena som tänkt? Ligger felet i systemet eller i tillämpningen av det? Syftet med denna uppsats är att studera vad som orsakar glappet mellan teori och praktik, genom att studera hur hushållningsbestämmelserna tillämpas i fem utvalda kommuner. Syftet med studien är också att hitta intressanta frågeställningar för vidare studier av ämnet. Problemet preciseras till skillnaden mellan tillämpningen av lagstiftningen och hur det var tänkt att tillämpas. I uppsatsen studeras bland annat hur kommuners organisation och politiska styrning påverkar tillämpningen. Tre metoder används. Interventionsteori för att tolka hushållningsbestämmelserna, komparativ analys för att identifiera faktorer som kan påverka kommunernas arbete med riksintressen och kvalitativ intervju för att uppnå fördjupad kunskap om kommunernas arbete. Hushållningsbestämmelserna i miljöbalkens 3 och 4 kapitel kan härledas direkt till riksplaneringen under 70- och 80-talet. Naturresurslagen trädde i kraft 1987, och hushållningsbestämmelserna överfördes oförändrade till Miljöbalken 1998. Flera modeller har används för att visualisera hur samordningen mellan myndigheterna ska ske, både under fysiska riksplaneringen och under senaste året. I kapitel 5 sammanfattas interventionsteorin och två systemmodeller konstrueras. I kapitel 6 beskrivs hur kommunernas särskilda redovisning av riksintressen i översiktsplanen. Tre faktorer studeras: hur riksintressena redovisas; om samtliga hushållningsbestämmelser redovisas; om kommunen beskriver hur säkerställandet av riksintresseanspråken ska ske. Studien av översiktsplanerna visar att tre av kommunerna redovisar riksintressen i ett särskilt kapitel eller bilaga. Två av kommunerna redovisar samtliga hushållningsbestämmelser och tre av kommunerna beskriver säkerställandet av åtminstone något riksintresse mer utförligt. Två av kommunerna bedöms ha ett i huvudsak fullständigt underlag i översiktsplanen för att arbeta vidare med riksintressen i planeringen och bygglovshandläggning. I kapitel 7 jämförs kommunerna i ett antal faktorer som tros påverka hur kommunen redovisat riksintressen i översiktsplanen. (94) 5 Faktorer som invånarantal, tillgång till fördjupat kunskapsunderlag och politisk styrning studeras och jämförs mellan kommunerna. I kapitel 8 redovisas intervjuer med tjänstemän och politiker i de studerade kommunerna samt de berörda länsstyrelserna. Från intervjuerna identifieras ett antal teman som viktiga att belysa. Kunskaps- och planeringsunderlaget är mycket viktigt för kommunernas planering, och översiktsplaneringen är viktig för att riksintressesystemet ska fungera. I kapitel 9 redovisas slutsatser. Slutsatsen är att det finns brister i kommunernas översiktsplaner när det gäller översiktsplanen som vägledande dokument för hur kommunen ska arbeta med områden av riksintresse i detaljplanering och bygglovshandläggning; att det finns skillnad i hur utförligt de olika riksintressena redovisas; att den kommunala organisationen kan påverka hur väl riksintressen redovisas och att det kan finnas samband mellan hur länsstyrelsen presenterar sin roll och hur kommunerna ser på sin roll.

    Kvinnors upplevelser efter avslutad behandling av gynekologisk cancer: En litteraturstudie2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: I Sverige diagnostiseras runt 2800 kvinnor varje år med gynekologisk cancer. Vid behandlingarna påverkas kvinnans reproduktionsorgan vilket medför en stor förändring i kvinnans liv. Till följd av den höga femårsöverlevnaden lever många kvinnor med följderna efter behandlingar av gynekologisk cancer. Kunskap om kvinnans upplevelser kan hjälpa sjuksköterskan att få ökad förståelse för kvinnan och därmed ge kvinnan ett bättre stöd.

    Syfte: Syftet med studien var att beskriva kvinnors upplevelser efter avslutad behandling av gynekologisk cancer.

    Metod: Metoden var en litteraturstudie med kvalitativ design baserad på åtta vetenskapliga artiklar. De vetenskapliga artiklarna analyserades med Graneheim och Lundmans beskrivning av innehållsanalys.

    Resultat: I resultatet framkom det att kvinnorna upplevde en förändring i att vara kvinna samt att de inte kände igen sina kroppar. Kvinnorna upplevde även en påverkan på deras sex och samliv, rädsla för återfall samt omvärdering av livet

    Slutsats: Efter behandling av gynekologisk cancer påverkades kvinnorna både fysiskt och emotionellt. Genom att sjuksköterskan visar empati, lyhördhet och respekt samt skaffar sig kunskap och förståelse för kvinnorna och deras upplevelser, kan ett bättre möte och en förbättrad omvårdnad åstadkommas.

    Impact of Sidewall Pressure on High Voltage Cables2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    When a high voltage cable is transported throughout factory it is affected by sidewall pressure in cable bends between the roller supports and the cable. The problem is when the sidewall pressure is too high it will deform the cable which can have a negative impact on the conductivity of the cable. The roller supports can also get damaged because of fatigue. These negative consequences are the subject to exploration by implementing known analytical solution of contact mechanics developed by Hertz together with finite element analysis and experimental testing.

     

    Two possible methods of measuring the radial force is studied to be able adjust the roller supports positions to reduce the sidewall pressure on the cable. The first one is to use the pressure film to determine the radial force. The second one is to by measuring the compression in cable to thereafter translate it to radial force by having the relation between compression and radial force for the specific cable.

     

    Two different types of high voltage cables, a direct current (DC) cable and an alternating current (AC) cable is studied by using finite element method and experimental tests to see the relation between the compression and radial force in the cable. Also in these experimental tests the pressure films are used and evaluated to see if this measuring technique combined with Hertzian’s theory make it possible determining the radial force.

     

    For the method of using the pressure films to determine the radial force the result shows it is difficult to translate the pressure from the films to radial force for a high voltage because of the cable’s armouring wires. The conclusion about these the pressure films is that they are good to use to describe the compression and can be used as relative measurement between the rollers but not for determine the radial force.

     

    The result shows it is a possible to describe relation between compression and radial force for a high voltage cable and use this information to determine the radial force by measuring the compression. But the conclusion is that it is ineffective and less accurate way of measuring the radial force.

     

    These results from this thesis are important for further research within the area and they help creating a greater understanding of sidewall pressure related problems in cables.

    Personers upplevelser tiden efter en kranskärlsoperation: -      Litteraturstudie2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Hjärt- och kärlsjukdomar är en av de vanligaste folksjukdomarna i världen. Under 2015 avled 15 miljoner personer till följd av sjukdomarna. En av behandlingarna vid förträngning av hjärtats kranskärl är en kranskärlsoperation. Operationen är nödvändig för att hjärtat ska få den syretillförsel som behövs, dock kan operationen innebära en risk för olika fysiska och psykiska komplikationer. En kranskärlsoperation kan påverka personers hälsa, livskvalité och livsstil. Kunskap om personers upplevelser efter en kranskärlsoperation kan bidra till att sjuksköterskan kan ge bättre stöd och information samt få en ökad förståelse för vad operationen kan innebära.

    Syfte: Syftet med studien var att beskriva personers upplevelser tiden efter en kranskärlsoperation.

    Metod: Metoden som användes var en litteraturstudie med kvalitativ ansats baserad på tio vetenskapliga artiklar. De vetenskapliga artiklarna analyserades utifrån en beskrivning av innehållsanalys för kvalitativa studier av Graneheim och Lundman (2004).

    Resultat: I resultatet framkom att personer upplevde både hälsa och ohälsa tiden efter en kranskärlsoperation. Personerna upplevde att en förändring i vardagen var nödvändig tiden efter operationen och betydelsen av stöd.

    Slutsats: Stöd och information har en betydelse för personers upplevelser tiden efter en kranskärlsoperation. Fysisk aktivitet framkom också som en bidragande faktor till att hälsa upplevdes. Genom att sjuksköterskan får en ökad förståelse och kunskap kring personers upplevelser tiden efter en kranskärlsoperation kan en god information, utbildning och stöd skapa en trygghet och en god hälsa. Vidare forskning rekommenderas för att studera hur personers tankar och känslor före operationen påverkar upplevelsen efter, samt eventuella skillnader i kön och ålder.

    Omvårdnadsarbetets påverkan av arbetsrelaterad stress hos sjuksköterskor: En litteraturstudie2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Arbetsrelaterad stress drabbar främst personer med ett yrke där kontakt med andra människor är i fokus som personal inom vård och omsorg. Kraven på hälso- och sjukvårdspersonal har ökat vilket har bidragit till upplevelser av höga krav och stress på arbetet. Sjuksköterskans ansvarsområden innefattar att främja individens hälsa, förebygga sjukdom och lindra lidande. Det ingår även att bemöta individen och dess närstående på ett tryggt och respektfullt sätt utifrån ett personcentrerat förhållningssätt. Arbetsrelaterad stress kan enligt forskning inte bara påverka sjuksköterskors hälsa utan även ha en inverkan på omvårdnaden av patienten.

    Syfte: Syftet var att ur sjuksköterskans perspektiv beskriva hur omvårdnadsarbetet påverkas av arbetsrelaterad stress.

    Metod: En kvalitativ litteraturstudie baserad på åtta vetenskapliga artiklar. Analysen utfördes med hjälp av Graneheim och Lundmans beskrivning av innehållsanalys.

    Resultat: Vid analysen framkom det att omvårdnadsarbetet påverkades av den arbetsrelaterade stress som berodde på tidsbrist. Resultatet visar att arbetsrelaterad stress påverkade omvårdnadsarbetet genom att sjuksköterskorna beskrev att de inte kunde kommunicera med patienter och dess närstående. Även omvårdnadshandlingar blev försenade eller uteblivna. Omvårdnadsarbetet påverkades även genom att patientens säkerhet hotades. Stress medförde begränsningar i sjuksköterskornas arbete då de inte kunde utföra den vård som de ansåg vara adekvat.

    Slutsats: Resultatet visar att den omvårdnad som sjuksköterskorna ansåg var adekvat blev påverkad av arbetsrelaterad stress. Sjuksköterskorna beskrev att de inte kunde leva upp till de förväntningar som ställs på dem i deras yrkesroll. Genom en ökad förståelse av hur omvårdnadsarbetet påverkas kan det bidra till en god utveckling inom vårdorganisationen, vilket i sin tur kan gynna patientens omvårdnad.

    Conceptualising Knowledge in Spatial Planning and Displacement of “the Political”2017In: DISP, ISSN 0251-3625, E-ISSN 2166-8604, Vol. 53, no 4, p. 33-41, article id RDSP 1414487Article in journal (Refereed)
    Abstract [en]

    This paper argues that organising spatial planning policies by funding local projects constitutes a steering mode that organises knowledge in such a way that it contributes to displacing “the political” in local spatial planning practice. “The political” is conceptualised as a space of agonistic conflicts and choicemaking (Mouffe 2005a). Such an organisation of knowledge operates to consolidate the initial framing of the problem, in which the goal and the possibility to monitor the goal is in focus, rather than challenging or questioning it in the name of justness and fairness. This is illustrated through an analysis of conceptualisations of knowledge within 127 project applications within the Swedish government's Safe and Gender Equal planning policy (2008–2010), which the National Board of Housing, Building and Planning facilitated in conjunction with the County Administration Boards of Sweden.

    Demanding Certainty: A Critical Examination of Swedish Spatial Planning for Safety.2016Doctoral thesis, monograph (Other academic)
    Abstract [en]

    This dissertation constitutes a critical examination of Swedish spatial planning for safety. Spatial planning for safety rests on a number of assumptions about the desired order of the world. These assumptions appear as given and unproblematic, making the formulation of alternatives appear unnecessary. This dissertation provides an account of how, and on what basis a spatial planning problem such as ‘fear and insecurity’ is formulated and acted upon. It is an account of how and what conceptions of knowledge operate to legitimise ideological representations of spatial planning problems. And furthermore, what these ideological representations of spatial planning problems substantially entail, so as to allow for a political spatial planning practice that formulates and deliberates alternatives. This is carried out by analysing assumptions of public life and knowledge within Swedish spatial planning for safety. 

    This dissertation finds that Swedish spatial planning for safety constitutes ‘certainty’ as a hegemonic criterion for participating in public life, which operates to limit the articulation of alternative discourses in spatial planning for safety. The desired for safe public life is organised based on visual certainty, where the urban fabric should be configured in such ways as to allow for stereotypical visual identifications of one another. Such a public life reflects an individualised practice, where perceptions of fear should be governed by individuals themselves, by independently assessing situations and environments in terms of risks. This individualised conduct is coupled with the fostering of active subjects, which encompasses being engaged in the local residential areas as well as in one another. Such substantial content of ‘planning for safety’ brings about tensions in terms of its ideological legitimating basis, by moving from principles of ‘rights’, where the individual constitutes the first ethical planning subject, to unitary principles of ‘collective values’, in which the ‘community’ constitutes the first ethical planning subject. These presuppositions are further enabled through the ways in which knowledge is conceptualised in spatial planning. This dissertation argues that a hegemonic instrumental emphasis on knowledge in spatial planning prevails. Having such a hegemonic emphasis on knowledge has the implication that even though spatial planning adopts different assumptions, or moves between alternative assumptions of knowledge, the knowledge becomes meaningful only in its instrumental implementation. The instrumental emphasis on knowledge should be regarded in light of the rational and goal-oriented nature of project-based planning, which constitutes a logic that constrains the emphasis on knowledge in spatial planning. This dissertation argues further that if spatial planning should be considered a political practice that debates its goals and values, a politicisation of the emphasis on knowledge in spatial planning is imperative.

    Safety and Agonistic Conceptions of Public Life2015In: PlaNext, ISSN 2468-0648, Vol. 1, p. 50-64Article in journal (Refereed)
    Abstract [en]

    This paper seeks to enable for conceptual resistance towards a desirable urban order of ‘safe public realms’, to which the ‘planning for safety’ directly contributes. One way of engaging in that kind of resistance is by contributing to politicising the system of beliefs informing planning for safety. Planning for safety is primarily legitimised morally as the ethically right thing to do given the identified violation of a human right in the public realm, the right to freely move about in the public environment. By drawing from Mouffean agonistic political theory (2005), there is no given interpretation nor implementation of ethical principles such as human rights, but rather different interpretations given what point of reference one is departing from, and should hence be subjected to political struggle. To conceptually set the arena for choice contributes to politicising phenomena which previously have been legitimised as the right or the (only) natural thing to do. ‘Planning for safety’ should therefore be interpreted resting on specific ideological assumptions of public life which frames both how ‘the human right’ is conceptualised as well as what planning solutions are considered possible.This article seeks to establish alternative conceptualisations of public life, with an aim to make visible how there is not one notion of public life and thereby re-politicise the ideolo-gical premises underpinning ‘safety planning’ and thereby allow for conceptual resistance. This is carried out by establishing a discursive field of public life, a kind of conceptual arena for choice making. The discursive field is represented by four different discourses of public life centred around different ideals such as rational, dramaturgical, conflictual and consensual public life. In this conceptual context, lines of conflict have been discerned based on a thematic of purpose, character, criteria for participation and conception of identities, which have taken the form of agonistic dimensions, from which planning discursively can position itself. This paper argues that we first must agonistically agree on what notion of public life should govern the development of our cities, and thereafter discuss what the consequences would be for planning.
