    Tvåsamhället: Om att förhålla sig till normer som skaver2008Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This study focuses on single peoples construction of their lifes in relation to normative heterosexual coupledom. It is based on five interviews made with single women and men at the age of 24 to 51 who live by themselves. The queer theory which puts the heteronormativity in question is used as a theoretical framework. Discourse psychology functions as an analytic approach. It focuses on the use of language in the construction of reality in a world of determinant discourses. The thesis shows how the life of singles is made understandable where the interviewee´s constructs their reality by either creating their own life's as possible ways of living and distance themselves from coupledom or by striving for the twosome way of living. This is done by a construction of gender and age performance as different in the single and the twosome life. It also shows paradoxes where discourses of advantage independence meet discourses that construct twosome relationships as the only place for the development of real masculinity or of a special form of preferable femininity. The construction of gender and age as performed different in the single and the couple life provides an understanding of the interviewee's creation of self-image in relation to normative heterosexual coupledom.

    Design and Application of Software Sensors in Batch and Fed-batch Cultivations during Recombinant Protein Expression in Escherichia coli2008Independent thesis Advanced level (degree of Master), 20 points / 30 hpStudent thesis
    Abstract [en]

    Software sensors are a potent tool to improve biotechnological real time process monitoring and control. In the current project, algorithms for six partly novel, software sensors were established and tested in a microbial reactor system. Eight batch and two fed-batch runs were carried out with a recombinant Escherichia coli to investigate the suitability of the different software sensor models in diverse cultivation stages. Special respect was given to effects on the sensors after recombinant protein expression was initiated by addition of an inducer molecule. It was an objective to figure out influences of excessive recombinant protein expression on the software sensor signals.

    Two of the developed algorithms calculated the biomass on-line and estimated furthermore, the specific growth rate by integration of the biomass changes with the time. The principle of the first was the application of a near infrared probe to obtain on-line readings of the optical density. The other algorithm was founded on the titration of ammonia as only available nitrogen source. The other two sensors analyzed for the specific consumption of glucose and the specific production of acetate and are predicted on an in-line HPLC system.

    The results showed that all software sensors worked as expected and are rather powerful to estimate important state parameters in real time. In some stages, restrictions may occur due to different limitation affects in the models or the physiology of the culture. However, the results were very convincing and suggested the development of further and more advanced software sensor models in the future.

    Implementering av TPU: En fallstudie om implementeringen av TPU på ABB Cewe-Control i Nyköping2008Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    If Swedish companies are to compete with companies in low-cost countries they have to achieve a more efficient production. The purpose of Total Productivity Maintenance (TPM) is to increase the company's profitability by increasing the productivity. TPM is a method that involves all employees and aims to prevent failures in order to increase the availability of existing equipment.

    The aim of this paper is to evaluate the implementation process of TPM and give recommendations for the further implementation process. The conclusion and the analysis are based on a case study done at a production department at ABB Cewe-Controls facilities in Nyköping. The case study consists mainly of qualitative data from participation observations, surveys and interviews.

    Commitment of the management is a key factor in the implementation process of TPM. The management of ABB Cewe-Control need to demonstrate their commitment in order for a change to happen. The case study shows that the commitment of both employee and management must be raised if the implementation process is to be successful. To avoid unnecessary conflicts or irritation in the further implementation process it is important to clarify responsibilities and roles in the implementation of TPU.

    The case study has also shown that the training during the implementation process has not been sufficient. Proper training is needed to be able to conduct the implementation process of TPM in an effective manner. Proper training is also needed to raise the motivation of the staff.

    Business Development is ABB’s methodology for the improvement work in the company. Business Development is a well-known concept in the organisation and has a well-defined connection with the company's strategic objectives. Because of this there is no reason why the improvement work and how it has been done should change. Business Development is a good foundation for the implementation of TPM and the improvement work in the future.

    A feasibility study of building Set-top box user interfaces using Scalable Vector Graphics2008Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    An IPTV Set-top box enables the possibility of doing much more than decodingtelevision content. Its Ethernet interface gives it the same possibilities to communicatewith the outside world as any network device. This enables a wide rangeof services from internet radio to acting as a digital media receiver in your homenetwork. These highly interactive services increase the demands for responsiveand visually attractive user interfaces.Due to the cost-sensitive market of IPTV STBs the preferred platform to developthe user interface is the HTML browser as it allows for fast developmenttimes and low costs. As a W3C standard it also offers high portability and hardwareabstraction making it easy to use more than one STB vendor. The cons ofHTML based GUIs are low performance and lacklustre graphics.This thesis aims to find out if SVG can be used to achieve rich, scalable and animatedgraphics with high performance and still keep the attractive characteristicsof HTML.To do this much effort was put into identifying the strenghts and weaknesses ofSVG. The lessons learned resulted in an SVG AJAX framework called TOIXSVGmaking it possible to develop SVG GUIs in the same manner as modern Rich InternetApplications, enabling component reuse to make sure development time scalespreferably with the scope and complexity of the user interface. Along with theframework several new widgets had to be developed to achieve the targeted functionality.As a proof of concept a mock-up GUI was created with the frameworkand widgets.

    Integrating geographic and information visualization for interactive exploration of statistical data2005Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The fast growing quantity of statistical data with geographical reference, accessible on the Web, creates a growing demand for more powerful exploratory analysis techniques for investigation of socio-economic phenomena in association with their geographical location. Statistics Sweden provides large amounts of census data of economic, social, demographic, and other matters of interest to the governments, government departments, local authorities, businesses, and to the general public.

    The current techniques available to analyze these data sets are limited. Therefore, this diploma work was put together, with the intention of integrating methods used in geographic visualization and information visualization into a prototype tool for interactive exploration of statistical data. This report investigates the tools present today and describes the development of a new one called GeoWizard - a tailor-made easy-to-use application for Statistics Sweden's databases.

    Kliniskt datainsamlingssystem med beslutsstöd - Användarutredning och gränssnitt för Sahlgrenskas akutintag2005Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

     Extra high requirements are made on all systems in health care that they are functional and usable,´something, however, that is not always the case. At Emergency Admissions at Sahlgrenska University´Hospital many systems are in use at the same time and it happens that much overhead is caused by having to fill in the same information in different places. In addition, data that is gathered is to a large extent saved in free text format, which means that it cannot be used in a larger context such as research, quality control or for decision support. Data is saved in the patient file only for the treatment process of the individual patient.

    A data collecting system with decision support functionality could be a first step towards reducing Emergency Admissions’ costs and patients’ waiting times by providing a structured method of data collection. It is also possible that it could contribute to safer care for patients as the system could warn the staff on occasions where there may be a risk of a patient suffering from a serious, acute illness that might be difficult to diagnose.

    An analysis has been performed at Emergency Admissions at Sahlgrenska to distinguish possible users of a new system for collecting data with decision support. The results showed that the nurses in reception were the most suitable target group.

    A prototype of a user interface for gathering initial patient data at reception has been made at Emergency Admissions at Sahlgrenska. This prototype has decision support functionality for ranking the most probable diagnoses as well as providing advice on suitable tests and examinations to perform. The focus has been on usability and on adapting the system to the needs of the users.

    It is highly important that future users, the staff at Emergency Admissions, continue to participate in the future further development of the data gathering system so that their needs and requirements are not overshadowed by the new technology.

    Natural Interaction Programming with Microsoft Kinect2011Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This report has the purpose of exploring the area of developing a natural interaction game using Microsoft Kinect. The launch of Kinect for Microsoft Xbox 360 has given us hardware for tracking humans, face recognition, speech recognition and 3D reconstruction for a relatively cheap price. This has created other areas of usage for Kinect than just in the area of games for Xbox. In this report I find out which development tools that are available today for developing applications for the PC platform and what they offer. I also choose one of them and develop a game with it with the purpose of evaluating the tool and also for getting the experience of creating an application with a natural user interface.

    The report is also part of a pre-study to introduce natural user interface applications into a game course at the university. This raises some requirements on the tools and therefore many of the discussions and results are with those requirements in mind. Those requirements being mainly that the tools should be available on the Windows platform and that they should be easy to use.

    The results shows that the area of developing natural interaction applications is new and therefore the tools available today are not totally mature yet. There are free tools from open source communities and tools from companies that you have to purchase to use. Both of them are trying to find their own way when it comes to the features and distribution of the tools and therefore which way to take is not obvious.

    Also developing a natural user interface is not always that straight forward. When there are no buttons available at all, it changes what you can do and how you do things. I will share my experiences and thoughts of both the development tools and the game I created throughout the report.

    Physical modelling of the Akkajaure reservoir2003In: Hydrology and Earth System Sciences, ISSN 1027-5606, E-ISSN 1607-7938, Vol. 7, no 3, 268-282 p.Article in journal (Refereed)
    Abstract [en]

    This paper describes the seasonal temperature development in the Akkajaure reservoir, one of the largest Swedish reservoirs. It lies in the headwaters of the river Luleiilven in northern Sweden; it is 60 km long and 5 km wide with a maximum depth of 92 m. The maximum allowed variation in surface water level is 30 m. The temperature field in the reservoir is important for many biochemical processes. A one-dimensional lake model of the Akkajaure reservoir is developed from a lake model by Sahlberg (1983 and 1988). The dynamic eddy viscosity is calculated by a two equation turbulence model, a k-ε model and the hypolimnic eddy diffusivity formulation which is a function of the stability frequency (Hond o et al., 1993). A comparison between calculated and measured temperature profiles showed a maximum discrepancy of 0.5-1.0oC over the period 1999-2002. Except for a few days in summer, the water temperature is vertically homogeneous. Over that period of years, a weak stratification of temperature occurred on only one to two weeks a year on different dates in July and August. This will have biological consequences.

    Micro-Structuring of New Materials Combined with Electronic Polymers for Interfaces with Cells2012Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Materials based on novel Off-Stoichiometry Thiol-Ene polymers, abbreviated OSTE, show promising properties as materials forlow cost and scalable manufacturing of micro- and nanosystems such as lab-on-chip devices. The OSTE materials have tunablemechanical properties, offer possibility for low temperature bonding to many surfaces via tunable surface chemistry, and can beused in soft lithography. Unlike the commonly used elastomer poly(dimethylsiloxane), PDMS, the OSTE materials have lowpermeability for gasses, are resistant to common solvents and can be more permanently surface modified.In this master’s thesis project, the OSTE materials have been evaluated with focus on compatibility with cells, possibility fornanostructuring using soft lithography and the use of OSTE as a flexible support for conducting polymers.Results from cell seeding studies with HEP G2 cells suggest that cells can proliferate on a low thiol off-stoichiometry OSTEmaterial for at least five days. The biocompatibility for this type of OSTE material may be similar to poly(styrene). However, highlevels of free thiol monomers in the material decrease cell viability considerably.By using soft lithography techniques it is possible to fabricate OSTE nanochannels with at least the dimensions of 400 nm x 15nm. Combined with the advantages of using the OSTE materials, such as low temperature bonding and possibility for stablesurface modifications, a candidate construction material for future development of systems for DNA analysis is at hand.OSTE can serve as a flexible support for an adsorbed film of a conducting polymer with the possibility for future applicationssuch as electronic interfaces in microsystems. In this project, a film of PEDOT:PSS with the electrical resistance of ~5 kΩ wascreated by adsorption to an flexible OSTE material. Furthermore, results suggest that it is possible to further optimize theconductivity and water resistance of PEDOT:PSS films on OSTE.

    Användarbehov och kontextuella krav för val av mobil interaktionsteknik: Behovs- och användarundersökning i Scanias verkstäder2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Mobil informationsteknik har på senaste tiden fått mer uppmärksamhet inom industriella applikationer, inte minst inom underhåll och reparation där teknisk dokumentation förekommer i stor utsträckning. Scania har tagit fram ett nytt koncept för interaktion med teknisk dokumentation i verkstaden där en viktig del av konceptet är mobilitet. Scanias förhoppningar är att en ökad möjlighet till mobilitet ska kunna förbättra användarupplevelsen.

    I detta arbete har en observationsstudie genomförts för att identifiera användarnas behov av mobilitet vid reparation och underhållsarbete samt de kontextuella faktorer som påverkar val av mobil interaktionsteknik.

    Fyra olika behov av mobilitet kunde identifieras efter analysen och till dessa kunde olika krav knytas för att skapa ett underlag för bedömning av olika teknikers potential att uppfylla de aktuella behoven.

    Design of Gas Shield for Friction Stir Welding Machine2014Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The research and development of the final disposal of the nuclear waste produced by the nuclear power plants is an important work done by The Swedish Nuclear Fuel & Waste Management Co. (SKB). As the demands on a final disposal increase the laboratory equipment has to be better in order to do valid experiments. Research on how the copper canister for the spent fuel will be manufactured and handled is done at the Canister laboratory in Oskarshamn, Sweden. The work presented in this report was to design a new gas shield for the friction stir welding machine at the laboratory. The welding machine seals the canisters containing the spent fuel which are then transported to the final disposal 500 meter down in basement rock. To minimize the amount of oxide particles in the weld zone SKB have to design a better gas shield that should deliver the required atmosphere around the welding area.

    The work contains a pre study phase where the important things to consider when designing are collected. Then ideas are generated and concepts created for a new gas shield. These concepts are evaluated by a pair wise comparison method in order to find the most promising concept. The concept chosen is then detail designed to come as close to a manufacturable design as possible.

    Post-Deployment Usability Opportunities: Gaining User Insight From UX-Related Support Cases2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    UX-related issues is one type of issue that customer support is facing. This thesis project investigates the possibility to look at support cases as a source of insight to how users interact with an information system application at an ERP company. It is also investigated if it is possible to use this gathered information when further developing the product. Support case data are gone through in order to map what type of problems the users are encountering and a category structure is developed based on this information. The categorization framework is evaluated by letting employees test the structure by categorizing incidents in to different categories. Further data collection are gathered by a questionnaire and follow-up interviews with the classification participants. To evaluate the value in the support case information, employees with product responsibility are also interviewed to get insight from their perspective.

    The result from the evaluation of the category structure indicated that it wasn’t easy to make a categorization of incidents. The incidents were placed in different categories and in order to apply a category structure it would need further evaluation before applying in large scale.

    The information in support cases are concluded to be valuable. The collection of information related to where users are encountering problem and also how many are experiencing the same issue could serve as a basis when prioritizing the product backlog. A mapping of issues could justify resources spent on usability by showing business value based on the presumed impact.

    Outsourcing och backsourcing av IT-lösningar: Utveckling och bakomliggande faktorer2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Outsourcing, that is to say when an organization's services or products within a function or an activity are being contracted out to an external vendor, became increasingly noticeable during the 1990s. The trend has grown to represent the norm in today’s society and nowadays organizations outsource operations ranging from the management of information technology (IT) to whole functions. The outsourcing of IT is considered to be a growing and increasingly global phenomenon. However, problems with an outsourcing agreement or changes in a company's business situation can lead to backsourcing, a concept meaning that an organization chooses to bring back and re-implement activities within its own operations. Decisions regarding the outsourcing of IT solutions have been a central aspect in both research and practice while the decision to change supplier or backsource has received relatively little attention. Nevertheless, the drivers of backsourcing constitute an equally relevant topic to study. Hence, the aim of this study is to identify the motives underlying an organization’s decision to outsource, as well as backsource, IT related activities and functions and to examine how the conditions that applied when making the decision to outsource can change during an outsourcing process. 

    I have conducted a qualitative study where a case study design has been applied. A number of organizations that use IT and IT solutions in their day-to-day operations have been studied where the organizations previously have backsourced and/or now find themselves in the process of bringing back their IT. A literature review has been conducted and empirical data has been collected through the use of semi-structured interviews. In the analysis, the empirical data has been analyzed in relation to previous research regarding (1) outsourcing and (2) backsourcing. 

    The results of this study show that reasons and motives that can result in a firm's decision to outsource its IT include the possibility of achieving cost reductions, a greater flexibility and the possibility of gaining access to expertise. Examples of changes that can occur during an outsourcing process are within the management since the replacement of an organization’s management can bring new opinions and attitudes towards the firm’s sourcing strategy. The importance of IT to the operations can also change during an outsourcing process. Furthermore, a number of underlying factors that may affect an organization’s decision to backsource its IT have been identified. Examples of factors are that the outsourcing has resulted in no overall cost savings and that there’s a lack of compliance with the contract regarding, for example, the quality of the services being delivered.

    Exosomen – intercellulär signalbärare med framtids­potential [Exosomes - intercellular signal carriers with a future potential]: Kan ge nya diagnostiska och terapeutiska möjligheter [May provide new diagnostic and therapeutic opportunities]2013In: Läkartidningen, ISSN 0023-7205, E-ISSN 1652-7518, Vol. 46, no 110, 2050-2052 p.Article in journal (Other academic)
    Abstract [en]

    Small vesicles were first described in prostatic and seminal fluids more than 30 years ago [5]. They were called prostasomes and are members of the same family now called exosomes. All cells in the body can release extracellular vesicles that function as intercellular messengers. The smallest of these, exosomes, are produced by almost all types of cells in the body and exist in all body fluids. Exosomal signalling takes place in two different ways: either with a cargo of functional proteins and/or by transfection of functional RNA molecules from one cell to the cytoplasm of another, or by ligand-receptor mediated interactions between molecules of the exosome membrane and the cellular membrane of the target cell. The importance of exosomes both in health and disease is rapidly acknowledged and clinical applications in diagnosticts and therapy are under development. The content of proteins and nucleic acids of exosomes will soon be used as bio markers for different diseases such as cancer and cardiac disease. Clinical tests are ongoing where exosomes are used as natural vectors for cancer specific peptides in the treatment of cancer. Exosomes will most probably soon be used in therapy by using them as natural vectors for new  RNA based therapies and also for follow up of therapy.

    Two-Dimensional Nb-Based M4C3 Solid Solutions (MXenes)2016In: Journal of The American Ceramic Society, ISSN 0002-7820, E-ISSN 1551-2916, Vol. 99, no 2, 660-666 p.Article in journal (Refereed)
    Abstract [en]

    Herein, two new two-dimensional Nb4C3-based solid solutions (MXenes), (Nb-0.8,Ti-0.2)(4)C3Tx and (Nb-0.8,Zr-0.2)(4)C3Tx (where T is a surface termination) were synthesizedas confirmed by X-ray diffractionfrom their corresponding MAX phase precursors (Nb-0.8,Ti-0.2)(4)AlC3 and (Nb-0.8,Zr-0.2)(4)AlC3. This is the first report on a Zr-containing MXene. Intercalation of Li ions into these two compositions, and Nb4C3Tx was studied to determine the potential of those materials for energy storage applications. Lithiation and delithiation peaks at 2.26 and 2.35 V, respectively, appeared in the case of Nb4C3Tx, but were not present in Nb2CTx. After 20 cycles at a rate of C/4, the specific capacities of (Nb-0.8,Ti-0.2)(4)C3Tx and (Nb-0.8,Zr-0.2)(4)C3Tx were 158 and 132 mAh/g, respectively, both slightly lower than the capacity of Nb4C3Tx.

    Study of the Optical Properties of sp2-Hybridized Boron Nitride2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Nitride-based semiconductor materials make it possible to fabricate optoelectronic devices that operate in the whole electromagnetic range, since the band gaps of these compounds can be modified by doping. Among these materials, the sp2-hybridized boron nitride has properties that make it a potential candidate for integration in devices operating in the short-wavelength limit, under harsh environment conditions, due to the strength of the B-N bond.  Nevertheless, this binary compound has been the less studied material among the nitrides, due to the lack of complete control on the growth process.

    This thesis is focused on the study of the optical properties of sp2-hybridized boron nitride grown by hot-wall chemical vapor deposition (CVD) method, at the Department of Physics, Chemistry and Biology, at Linköping University, Sweden. The samples received for this study were grown on c-plane aluminum nitride as the buffer layer, which in turn was grown by nitridation on c- plane oriented sapphire, as the substrate material. The first objective of the research presented in this thesis was the development of a suitable ellipsometry model in a spectral region ranging from the infrared to the ultraviolet zones of the electromagnetic spectrum, with the aim of obtaining in the process optical properties such as the index of refraction, the energy of the fundamental electronic interband transition, the frequencies for the optical vibrational modes of the crystal lattice, as well as their broadenings, and the numerical values of the dielectric constants; and on the other hand, structural parameters such as the layers thicknesses, and examine the possibility of the presence of roughness or porosity on the boron nitride layer, which may affect the optical properties, by incorporating their effects into the model. The determination of these parameters, and their relation with the growth process, is important for the future adequate design of heterostructure-based devices that incorporate this material. In particular, emphasis has been put on the modeling of the polar lattice resonance contributions, with the TO- LO model, by using infrared spectroscopic ellipsometry as the characterization technique to study the phonon behavior, in the aforementioned spectral region, of the boron nitride. On the other hand, spectroscopic ellipsometry in the visible-ultraviolet spectral range was used to study the behavior of the material, by combining a Cauchy model, including an Urbach tail for the absorption edge, and a Lorentz oscillator in order to account for the absorption in the material in the UV zone. This first step on the research project was carried out at Linköping University. 

    The second objective in the research project was to carry out additional studies on the samples received, in order to complement the information provided by the ellipsometry model and to improve the model itself, provided that it was possible. The characterization techniques used were X-ray diffraction, which made it possible to confirm that in fact boron nitride was present in the samples studied, and made it possible to verify the crystalline quality of the aforementioned samples, and in turn relate it to the quality of the ellipsometry spectra previously obtained; the Raman spectroscopy made it possible to further verify and compare the crystalline qualities of the samples received, as well as to obtain the frequency for the Raman active B-N stretching vibration in the basal plane, and to compare this value with that corresponding to the bulk sp2-boron nitride; scanning electron microscopy made it possible to observe the rough surface morphologies of the samples and thus relate them to some of the conclusions derived from the ellipsometry model; and finally cathodoluminescence measurements carried out at low temperature (4 K) allowed to obtain a broad band emission, on all the samples studied, which could be related to native defects inside the boron nitride layers, i.e., boron vacancies. Nevertheless, no trace of a free carrier recombination was observed. Considering that the hexagonal-boron nitride is nowadays considered to be a direct band gap semiconductor, it may be indirectly concluded, in principle, that the dominant phase present in the samples studied was the rhombohedral polytype. Moreover, it can be tentatively concluded that the lack of an observable interband recombination may be due to the indirect band gap nature of the rhombohedral phase of the boron nitride. Spectroscopic ellipsometry does not give a definite answer regarding this issue either, because the samples analyzed were crystalline by nature, thus not being possible to use mathematical expressions for the dielectric function models that incorporate the band gap value as a fitting parameter. Therefore, the nature of the band gap emission in the rhombohedral phase of the boron nitride is still an open research question. On the other hand, luminescent emissions originating from radiative excitonic recombinations were not observed in the cathodoluminescence spectra. This second step of the project was carried out at the Leroy Eyring Center for Solid State Science at Arizona State University.

    Premenstruellt syndrom: Symptom och coping2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Studien har undersökt symptom samt hantering av PMS genom en enkätstudie där 72 kvinnor i åldrarna 18-49 deltagit. Syftet med studien var att beskriva symptombild och kvinnors sätt att hantera PMS. Fokus riktades mot vad kvinnorna gör för att hantera upplevda symptom och vi har tittat på olika samband. Resultaten visade att de allra flesta kvinnor upplever något PMS-symptom och förekomsten är hög (98,5%) med en spridd symptombild. Mest förekommande symptom när det gäller svåra besvär var ilska/lättretlighet, gråtmildhet och fysiska symptom. Det vanligaste sättet att hantera och förhålla sig till sin PMS i vår studie är ett medvetet och accepterande förhållningssätt. Att äta sötsaker, undvika sociala aktiviteter samt träna mindre har ett signifikant negativt samband med känslan av att kunna hantera sin PMS. Studien har även belyst att ökad medvetenhet hos kvinnor kan gynna deras förmåga att hantera PMS och föreslår fortsatt forskning inom området med fokus på behandlings metoder.

    Hur projektstyrningsmodeller påverkas av kontextuella och kulturella faktorer inom IT.: En studie om överföring.2015Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Globaliseringen är ett ämne som möter oss varje dag även om vi tänker på det eller inte. Vi använder utländska produkter och kanske även använder olika metoder att genomföra saker på som har sitt ursprung i en annan världsdel. Företag arbetar på daglig basis med projekt och IT-projekt över hela jorden. Vår studie syftar till att undersöka hur kulturella och kontextuella faktorer påverkar internationella företag när nya projekt och IT-projekt initieras i andra länder. Till hjälp använder vi oss bland annat av Hofstedes kulturdimensionsteorier som beskriver hur olika länder skiljer sig åt gällande kultur i fem olika dimensioner. Vi använder oss även av konvergensteorier, divergensteorier samt teorier kring translation som behandlar hur modeller och teknologi kan appliceras i nya kontexter. Konvergensteorier menar att modeller är universella samt att företag och länder är homogena varför det går att direkt översätta modeller utan att de behöver anpassas. Divergensteorier menar att heterogenitet existerar och att modeller således behöver anpassas till kontext. Translation är en blandning av divergens och konvergens. Vi har avgränsat oss till att enbart undersöka projektarbeten och kommer därför att definiera vad temporära organisationer är och vad de innebär samt att vi kommer reda ut projektstyrning. Detta har skett genom en hermeneutiskt kvalitativ studie där vi använt en abduktiv ansats. Empiri har samlats in genom semistrukturerade intervjuer som sedan tematiserats för analys. Studiens resultat visar att projektstyrningsmodellers överföring och implementering och dess användande påverkas av branschspecifika faktorer, nationell kultur samt organisationskultur. Studien har visat att det i implementeringsfasen krävs en medveten översättning som resulterar i en form av anpassning med hänsyn till i synnerhet organisationskultur, som påvisar och styrker en divergent heterogenereringsprocess. Vid en internationell överföring eller brukande av en projektstyrningsmodell i ett internationellt sammanhang måste även olika kulturella aspekter beaktas.

    Key performance indicators for the evaluation of an air navigation service providers' safety management system2016Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Safety is the main concern of the aviation industry. All Air Navigation Service Providers must have a Safety Management System (SMS) which states how safety is handled, promoted and prioritized. By developing Key Performance indicators (KPIs), it is possible to quantify the effectiveness of a SMS, discover potential flaws and improvement measures. This thesis identifies principles behind the SMS, the development of KPIs and suggest potential KPIs for the Swedish air navigation service provider LFVs’ SMS.

    A literature study was performed and organisation specific documents were analysed to develop potential KPIs within the areas timely compliance with international obligations, competency and adoption and sharing of best practices based on an EASA questionnaire. This work presents a set of 27 performance indicators and recommends 6 as potential KPIs for the three areas together. The KPIs are developed specifically for LFV but could be applicable for other organisations with similar SMS structure and processes. They should be analysed within the organisation and, potentially, have thresholds set before implementation.

    Staten som förebild?: om planer, insatser och utfall i 17 myndigheters arbete med etnisk mångfald2004Report (Other academic)
    Abstract [en]

    The “State as a Role Model” report (Staten som förebild?) deals with the observance of the federal politicians’ regulatory instructions and ethnic diversity work in government authorities. The general idea is that the integration policy be taken seriously, both through giving concrete substance to the objective, of the state serving as a model, when it comes to ethnic diversity, and through examining adherence to this objective. The report focuses on planning, initiatives and outcomes. Working on the basis of the regulations set out by Swedish parliament and Government, the action plans of 17 federal authorities are examines with respect to ethnic diversity, the 17 authorities are asked about their work with diversity, and the outcome in their personnel numbers are mapped. The relationships between planning, initiatives and outcomes are considered, as are the regulatory instructions.

    Of the 17 authorities selected, 15 have drawn up action plans for promoting ethnic diversity. Generally speaking, most of these programs are weak from a content perspective, and the authorities’ diversity work is in need of holistic thinking. Methods for incorporating the integration policy into current day-to-day activities need to be developed.

    One overall impression gained from the interviews with the authorities is that internal work to increase and better utilize the diversity found in Swedish society is perceived as fairly new, and as yet both given relatively little reflection and rather shaky. All of the authorities interviewed need to further develop their diversity work, some more than others.

    When it comes to the outcome in personnel numbers, the percentage of foreign-born individuals working at the 17 authorities is in general considerably lower than the corresponding figure for foreign-born workers otherwise employed in the nation. The fact that foreign-born individuals are generally under-represented in federal administration is reflected in their also being under-represented in different occupations at the 17 authorities, especially with respect to management positions.

    One important observation is that, at most of the authorities surveyed in the study, there was a decline in the total number of employees between the years of 1997 and 2001, although this has not affected foreign-born employees, as is otherwise often the case. The need to hire new people at the 17 authorities during this period, as a whole, has been small. This means that any substantial changes in the composition of personnel through new recruitment have not been possible during the initial years of the integration policy.

    When focus is directed to the local and regional levels, and to the more concrete day-to-day work of the authorities, it becomes clear that an authority’s diversity work is characterized by the nature of its activities. Indepth study on the local and regional levels also shows the importance of organizing the work, as well as the importance of diversity for externally-oriented activities, and that diversity can be perceived as somewhat of a sensitive, new or unfamiliar issue. The closer analyses also show that organizations can follow independent strategies in relation to their plans for ethnic diversity.

    Even if no strong connections can be demonstrated between planning, initiatives and outcomes in the analysis in this report, the Swedish Integration Board feels it is too early to rule out the federal stipulation that authorities use special action plans in their work to promote ethnic diversity. One must remember that the integration policy is a new policy that involves long-range development processes, not all of which are subject to immediate impact. Before the policy is abandoned, the directives on diversity should be implemented in full. One way to make the policy more clear may be to write more specific demands into the directives and budget appropriations to the authorities.

    Festiketten: Developement of an E-commerce Web Application for custom designed bottle labels2015Independent thesis Basic level (degree of Bachelor), 12 credits / 18 HE creditsStudent thesis
    Abstract [en]

    The report examines how an online store for custom designed bottle labels can be developed as a web application, and aims to contribute to the existing research on web design. The development is based on the vision” to provide custom labels through an online store which puts the icing on the cake for your special occasion”, with persons in the age 25-40 who are planning a wedding or another large event as target group. The technical methods which can be used are presented in the report and what impact they had on the competitive aspects of the online store. Design strategies for building user trust are discussed among others, as essential parts of e-commerce according to the presented theory. Furthermore, the report presents more concrete technical methods for increasing the competitiveness such as faster loading times and search engine optimization. Especially loading times plays a central role for the success of a web application according to the related theory. The methods which has been used and why, considering the collected theory, are presented in the report. The conclusions of the report states that an online store successfully can be developed using an agile methodology such as Scrum and that it can take benefits from being implemented as a single page application. Developing a design tool for custom bottle labels proved to be a difficult balancing act between customization and simplicity.

    Högfrekvenshandel: En handelsteknik som kräver utveckling av regleringen samt övervakning2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Högfrekvenshandel är en växande handelsteknik på de finansiella marknaderna i både Sverige och USA. Genom införandet av EU-direktivet MiFID II i svensk rätt, kommer denna handelsteknik att regleras för första gången i Sverige. Även i USA finns ett regleringsförslag som väntar på att införas. Högfrekvenshandel är något nytt, teknologiskt och kontroversiellt på den finansiella marknaden och dess fördelar och nackdelar debatteras flitigt. I denna uppsats utreds vad högfrekvenshandel egentligen är, hur sådan handel kommer att definieras i lagtext, vilka för- och nackdelar som finns, samt vad de nya regleringarna kommer att innebära.

    En av de frågor som besvaras i uppsatsen är huruvida ett förbud mot högfrekvenshandel bör införas på den svenska marknaden. Svaret på den frågan är nekande. Om ett förbud mot högfrekvenshandel skulle införas, skulle det innebära ett steg tillbaka i såväl den tekniska som den ekonomiska utvecklingen. Den nya svenska regleringen angående högfrekvenshandel är ett viktigt steg för att lagstiftningen ska följa den tekniska utvecklingen. Regleringen kommer dock inte att medföra några nya regler för aktörerna på den finansiella marknaden, utan medför endast att de regler angående högfrekvenshandel som redan finns genom börsernas självreglering blir svensk lag.

    I denna uppsats presenteras både den svenska och den amerikanska finansiella marknaden, anledningen till detta är att skapa en djupare förståelse för den svenska regleringen och utvecklingen på den svenska finansiella marknaden. Den andra frågan som besvaras i uppsatsen har ett komparativt ändamål och tar sikte på vilka skillnader som finns mellan den svenska och den amerikanska marknaden vad gäller högfrekvens- och algoritmhandel. Den andra frågan besvaras löpande i uppsatsen genom jämförelse mellan de aktuella marknaderna. Enligt min åsikt är det inte många skillnader angående högfrekvenshandel på de två olika marknaderna. Till exempel är de risker med högfrekvenshandel som framställs för den svenska marknaden i stor utsträckning samma risker som framställs för den amerikanska marknaden. Jag kan även konstatera att högfrekvenshandel möjliggjordes på liknande sätt på både den svenska och den amerikanska marknaden, nämligen genom regelförändringar som främjade teknologisk utveckling på de finansiella marknaderna.

    ”Man är ju i ett tillstånd som inte går att beskriva”: att uppleva en närståendes självmord2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Målet med studien är att med kvalitativ metod undersöka efterlevandes upplevelse av en närståendes självmord. Med semi-strukturerade intervjuer har sex deltagare i Mellansverige skildrat sin upplevelse och materialet har bearbetats i enlighet med metoden Interpretative Phenomenological Analysis (IPA). Genom analysen synliggjordes tre områden nämligen 1) att uppleva en närståendes självmord, 2) att hantera en närståendes självmord och 3) att skapa mening kring en närståendes självmord. Dessa består i sin tur av ett antal teman som detaljerat beskriver varje del av den totala upplevelsen. Något som är särskilt värt att nämna är hur viktig omgivningens förståelse varit för att de efterlevande ska kunna bearbeta sitt trauma. Deltagande i stödgrupp för efterlevande har varit till hjälp samt den inre styrka som samtliga deltagare upplever sig ha anammat för att orka och utvärderat studiens begränsningar samt givit förslag på fortsatt forskning.

    Parkettläggning: med massivträ som utgångspunkt2015Independent thesis Basic level (degree of Bachelor), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    This thesis is about furniture parquetry and various techniques. Parquetry can be describe as wooden, 2-dimensional patterns used to garnish furniture and other products. It is manufactured in thin veneer layer and applied to the surface. By using thin veneer we are able to minimize stresses in the material, which results in tight joints. In Europe, furniture parquetry is traditionally created by wood veneer pieces that has been formed and joined into a pattern. There are also other proven techniques developed during different stages in history and in different places in the world.

    In my thesis I describe some of those established techniques and some of my experiments in the subject. The report is based on literature studies, observations of movie clips, interviews and empirical practical studies. I have compared different techniques to see in what ways it is possible to rationalize the production of furniture parquetry. At the same time I wanted to try and develop a method that makes it possible to create parquetry patterns containing round shapes. In this way I hope to contribute to the development and modernization in the area.

    Imagining Epigenetics: An explorative study of transdisciplinary embodiments, and feminist entanglements2014Independent thesis Advanced level (degree of Master (Two Years)), 80 credits / 120 HE creditsStudent thesis
    Abstract [en]

    This thesis proposes the relevance of epigenetic research to feminist studies and gender

    studies, and vice versa, and asks how epigenetics speaks to the so-called sex-gender

    distinction. It also discusses what epigenetics could potentially tell us about ourselves,

    and our place in a world where we are all creatures of both nature and nurture. The

    author proposes that with its promise of insight into the relationship of the body to

    environment and experience over time, epigenetics could be an inextricable link

    between nature and nurture. Combining a modified version of diffractive analysis, and

    gender/sex as an analytical device, the author engages with epigenetic research and its

    representation in popular science and in the public imaginary. After discussing the

    striations of feminist discourse on permeable bodies, the author proposes epigenetics as

    another layer in the strata, placing epigenetics within feminist and gender studies

    literature and discourse. Noting that as research gains ground the way in which the

    public imagines and describes epigenetics gives shape to its materialization and

    development, this thesis asserts the urgent need for social sciences, and in particular

    feminist and gender studies, to engage in critical discourse with epigenetic research as it

    is carried out and as it is translated to the wider public.

    Controller Design Enabling Automated and Fuel-Efficient Driving Strategies for Heavy Duty Vehicles in Urban Environments2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The automative industry drives the development towards more autonomous vehicles, this because of both safety and energy conservation reasons. This thesis focuses on solutions to lower the fuel consumption for heavy duty vehicles, which is more and more requested. Both due to increasing fuel costs and to greater environmental awareness. Through extensive simulations with a vehicle model, developed at and provided by Scania CV AB, different driving strategies are evaluated and analysed. This determined how to achieve a low fuel consumption when driving heavy vehicle in an urban environment. The simulations shows that the fuel consumption can be lowered by coasting the vehicle when deceleration and thus minimize the use of the brakes. One should also when possible, select a higher gear to lower the fuel consumption due to engine friction. These strategies are used to develop a controller which lowers the fuel consumption without increasing the trip time for the vehicle. The controller is able to alter the velocity of the vehicle within a reference window which results in both a lower fuel consumption and a shorter trip time for the driving cycle used.

    In pursuit of a perfect system: Balancing usability and security in computer system development2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Our society is dependent on information and the different technologies and artifacts that gives us access to it. However, the technologies we have come to depend on in different aspects of our lives are imperfect and during the past decade, these imperfections have been the target of identity thieves, cyber criminals and malicious persons within and outside the organization. These malicious persons often target networks of organizations such as hospitals, banks and other financial organizations. Access to these networks are often gained by sidestepping security mechanisms of computer-systems connected to the organization’s network.

    Often, the goal of computer-systems security mechanisms is to prevent or detect threats; or recover from an eventual attack. However, despite huge investments in IT-security infrastructure and Information security, over 95% of banks, hospitals and government agencies have at least 10 malicious infections bypass existing security mechanisms and enter their network without being detected. This has resulted in the loss of valuable information and substantial sums of money from banks and other organizations across the globe. From early research in this area, it has been discovered that the reason why security mechanisms fail is because it is often used incorrectly or not used at all.  Specifically, most users find the security mechanisms on their computers too complicated and they would rather not use it. Therefore, previous research have focused on making computer-systems security usable or simplifying security technology so that they are “less complicated” for all types users, instead of designing computers that are both usable and secure. The problem with this traditional approach is that security is treated as an “add-on” to a finished computer-system design.

    This study is an attempt to change the traditional approach by adjusting two phases of a computer-system design model to incorporate the collection of usability as well as security requirements. Guided by the exploratory case study research design, I gained new insights into a situation that has shocked security specialists and organizational actors alike. This study resulted in the creation of a methodology for designing usable and secure computer-systems. Although this method is in its rudimentary stage, it was tested using an online questionnaire. Data from the literature study was sorted using a synthesis matrix; and analyzed using qualitative content analysis. Some prominent design and security models and methodologies discussed in this report include User-Centered System Design (UCSD), Appropriate and Effective Guidance for Information Security (AEGIS) and Octave Allegro.

    Abstract [en]

    This report declares the experiences and results arrived from the development process around the e-shop Studentlunchen. Studentlunchen is a web application to be used by students to order lunch during weekdays. In order to make Studentlunchen as user friendly and intuitive as possible the e-shop has been developed with focus on functionality and an attractive design. In the report there is a technical description regarding the web application together with a discussion concerning the developed solutions. Furthermore the report discusses and evaluates the working process Scrum and how it has been used. As a result of complying with the Scrum methodology to deliver working functionality after every sprint, focus has been directed towards achieving this instead of implementing many features that isn’t fully completed. With thorough development of the initial prototype, the basic idea of the design and functionality surrounding Studentlunchen could be kept throughout the development process. This was one of the great contributors to the projects overall success and helped the team achieve the goal to make a user-friendly web application.

    Effekter av e-tjänster inom den offentliga vården: En kvalitativ fallstudie om hur e-tjänster kan påverka en offentlig vårdorganisations verksamhet och dess medarbetare2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    E-services are becoming increasingly prevalent in various contexts. Organizations in the public sector have also embraced this trend and today provide e-services with different purposes, e.g. various e-health services. Although there are advantages of e-services compared to traditional channels, they are not free of problems; a public organization must, among other things, provide an availability that private organizations may not need. This in turn means that the business needs to adapt its internal IT systems to handle incoming cases, which affects both the organization’s business and its employees. As today’s demands exceeds the resources, and that the population in Sweden is growing older, demands increase on the health care’s business. Citizens have to take greater responsibility for their own healthcare, which involves changes in working methods through effective e-services. Therefore, we examined the consequences this has within the business, as well as how the use of e-services affects the employees’ working routines and administrative work.

    The study aims to identify and analyze consequences, opportunities and obstacles with e-health and e-services within a public health care organization. In this way, we see that the study may help with possible explanations to the challenges that arise from the use of e-services in the public health care. The intention is also to identify and describe possible gaps between expected effects of strategies and the outcome in the operational business, which we see can contribute to greater understanding of the differences and how they might be handled. The study is based on a qualitative case study on Region Östergötland, where we have collected empirical data through interviews. The interviews have then been interpreted and analyzed to provide an illustration of how the organization strategically works with e-services in the public healthcare and how this is manifested in the business.

    The study results and conclusions show that there are both positive and less desirable effects of e-services within the operational level of the business. The same also applies to certain strategic decisions, particularly the decision to make patient records available through the e-service My health care contacts. We consider that an important contribution of the study is to highlight the needs from the operational health care business, as well as the importance of taking these into account in the development of e-health and e-service related strategies. We consider that another contribution of the study is the need to reflect on the business implications that may arise as a result of e-services.

    Cultural paradigm shifts in socio-technical transitions towards sustainable cities: A case study of the transportation system of São Paulo2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Transportation is a key component of the urban realm due to its high fossil fuel consumption, GHG emissions and pollution generation (among other negative externalities) that have been aggravated by an individual motor vehicle-driven society. In order to achieve a balanced urban growth for the future, the transportation paradigm requires a complete shift that will depend upon a change on people’s behaviors and perceptions about mobility. Being the biggest, most populous city of Brazil and the western hemisphere, as well as the financial motor behind the country’s economy, São Paulo currently faces a very serious transportation problem: an extremely high car per capita ratio in conjunction with a deficient public transport network. Furthermore, socioeconomic disparities exert an additional pressure to this dilemma, limiting the access to mobility and deeply embedding the car from a cultural standpoint. Given its prominence, São Paulo is the ideal city to evaluate how specific cultural and socio- spatial niches can steer a cultural paradigm shift that could ultimately trigger a socio-technical transition towards sustainability. In this case study, the role of policies, technology, and infrastructure as policymaking instruments are analyzed in the context of urban spaces in emergent nations, where political and economic structures are strong social determinants. Moreover, this study has shown how these instruments could not only produce a new set of mobility practices (or a new transportation culture) but also the creation of an equitable and thriving urban environment.

    Konsten att läsa mellan raderna: En studie om läs- och skrivutveckling2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Läs- och skrivsvårigheter är inte enbart ett växande problem i skolan utan även ett samhällsproblem. Den ökande kravbilden på läsförmåga i samhället bidrar till betydelsen av att utarbeta verkningsbara läs- och skrivstrategier bland elever med läs- och skrivsvårigheter. Samtidigt visar forskning att allt fler lärare känner en oro i att undervisa i lässtrategier, en oro som i mångt och mycket grundar sig i okunskap. Eftersom utvecklingen av lässtrategier utgör ett bedömningsunderlag i nationella provet i svenska och dessutom betonas i läroplanen (Lgy11) är det ett aktuellt forskningsämne som både belyses nationellt som internationellt. Forskning visar att det råder en slags konsensus kring vad som elever med god läsförmåga och läsförståelse har jämfört med vad elever med läs- och skrivsvårigheter inte har. Till exempel saknar de sistnämnda eleverna kompetens att göra inferenser och förutsäga kommande information i det de läser. Däremot går meningarna ibland isär vilka läs- och skrivstrategier som kan ha effekt för läs- och skrivutveckling och det är inte sällan brist på kunskap när det gäller att tillämpa läs- och skrivstrategier i praktiken.

    A study of Bitcoin as a currency for email-based micro-transactions2016Independent thesis Basic level (degree of Bachelor), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    Bitcoin is a cryptocurrency that has been the focus of a lot of discussions lately and has attracted a large number of users. Its offers many possibilities for cheap transactions and unregulated finances which has been realized in numerous sites and applications on the web and in mobile phones. One medium that seem to have been neglected when it comes to Bitcoins development is email. This is curious since Bitcoin by its nature seem to have many properties that would work well with texted messages. The purpose of this study it to analyze the current papers about Bitcoin to find the current status of email based Bitcoin services,  and try to analyze if email as a tool is a suitable medium to be used with Bitcoin. This analyze is done through a systematic literature review of current papers, followed by an examination of past and current Bitcoin companies that has used email as part of their service. In the end the results suggested that the low security in email, and the apparent lack of services that would benefit from an email based Bitcoin service suggest that a service like that would be hard to develop today and not very useful to the public.

    Expansion av e-handelsverksamhet i detaljhandeln: En studie om utmaningar och framgångsfaktorer2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The Internet has become a central part of the modern society and has change our everyday life in many ways. An area that’s been strongly affected by this development is the Swedish retail e-commerce market. E-commerce sales have increased six-fold over the course of the past decade and forecasts indicate that this expansive trend will continue. This trend places significant challenges on Swedish retail companies who have a legacy of exclusively carrying out their sales in the traditional brick and mortar format. The subject of this study was originally proposed by the Swedish retail company Företag X[1], who have decided to embark on their e-commerce initiative in early 2016. Företag X asked the author of this report to help with finding out what it takes to develop a small e-commerce store, in such a way that it becomes a successful part of the company, contributing to the company’s overall profitability. The purpose of this study is therefore to identify practices and methods that enable successful expansion of e-commerce for medium-sized, Swedish retail companies.

    In order to achieve the purpose, a qualitative multi-case study design was chosen for the study. Information for the theoretical framework was collected from articles in scientific journals and books, and supplemented with secondary empirical data in the form of reports from companies. Qualitative primary data were then collected from interviews with three chosen companies, which were found with through a small cross-sectional study of 20 competitors to Företag X where their EBITDA margins over the past five years were studied.

    The study results showed an expansive trend on the Swedish retail e-commerce market, and it seems that this trend is set to continue over the next decade. As a consequence, market climate is changing and shifting towards becoming more digitalized, which requires companies to review their sales organizations. The main trend in the market is called “omni-channel retailing" and means that a company is integrating its brick and mortar and e-commerce sales to enable a seamless shopping experience for the customer. This trend has emerged as a response to a new buying patterns observed among customers, who move between their digital and physical sales channels during the purchase.

    The study indicates that the e-commerce-related issues that are most important to address and work with are in the following areas:

    • Customer Focus
      • IT
      • Customer relations
      • Responsiveness to customers
    • Cost effectiveness
      • Supply chain and logistics
      • Strategy and governance
    • Resistance Management
      • Education
      • Synchronization between brick and mortar stores and e-commerce store

    This study represents the author’s master’s thesis in the Industrial Engineering and Management program at Linköping University, Sweden.

    Arbetsterapeuters erfarenhet av bedömningsinstrumentet Assessment of Work Performance – Försäkringskassan (AWP-FK) - En e-Delphistudie2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Försäkringskassan (FK) har i uppdrag av Sveriges regering att ge ekonomisk ersättning vid funktionsnedsättning och att utreda medicinska förutsättningar för arbete med tillförlitliga bedömningsverktyg. Vid kompletterande bedömning av medicinska förutsättningar för arbete har Försäkringskassan valt det arbetsterapeutiska bedömningsinstrumentet Assessment of Work Performance som en del av aktivitetsförmågeutredningen. En specifik tillämpning med namnet Assessment of Work Performance – Försäkringskassan (AWP-FK) har utvecklats. I tillämpningen ingår tre arbetsuppgifter; namnskyltsbeställning, sortering av post samt montering av hyllor. Syftet med examensarbetet var att undersöka hur yrkesverksamma arbetsterapeuter uppfattar och använder bedömningsinstrumentet AWP-FK. Metoden som valdes var en e-Delphistudie. Urvalet bestod av 11 yrkesverksamma arbetsterapeuter i Sverige som har arbetat med AWP-FK. Resultatet visar att arbetsterapeuterna tyckte att manualen var tydlig. Färdighetsområdet kommunikations- och interaktionsfärdigheter ansåg arbetsterapeuterna var svårt att bedöma med dagens arbetsuppgifter. Slutsatsen blev att det finns utvecklingsmöjligheter för AWP-FK vad gäller manualen, kommunikations- och interaktionsfärdigheter samt utveckling av nya arbetsuppgifter. I diskussionen diskuteras metodens tillförlitlighet och dess begränsningar. Metoden var fördelaktig eftersom svaren från runda ett gick att följa upp genom en konsensusberäkning. Slutsatsen blir att det är svårt att bedöma kommunikations- och interaktionsfärdigheter. Vidare diskuteras att det behövs fler arbetsuppgifter som bedömer kommunikations- och interaktionsfärdigheter samt att detta färdighetsområde bör utvecklas.

    Treat-to-target versus dose-adapted statin treatment of cholesterol to reduce cardiovascular risk.2016In: European Journal of Preventive Cardiology, ISSN 2047-4873, E-ISSN 2047-4881, Vol. 23, no 3, 275-281 p.Article in journal (Refereed)
    Abstract [en]

    Clinical guidelines should be based on the best available evidence and are of great importance for patient care and disease prevention. In this respect, the 2013 American College of Cardiology/American Heart Association report is highly appreciated and well-recognized. The report included critical questions concerning hypercholesterolaemia, but its translation into a clinical guideline initiated intense debate worldwide because of the recommendation to switch from a treat-to-target approach for low-density-lipoprotein-cholesterol to a statin dose-based strategy.

    Outcomes of applying lightweight code review in terms of error detection and perceived value and learning2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The problems a new start-up company face are numerous. Everything from restricted resources and

    a very high speed of development, to different backgrounds and levels of expertise and experience of

    the employees. Procedures have to be set in place in order to give everyone involved the same vision

    of the product, and to get the development up to speed as fast as possible.

    This case study implements a light weight code review protocol that is adopted by the programmers

    of the company, primarily to mitigate the problem of varying expertise. During the course of the

    study, measurements of errors detected and perceived value and learning were made. Finally,

    extrapolations of the data was done in order to see what could be generalised from this very specific

    case study to a broader context.

    Inte som andra kvinnor: - En studie om varför kvinnor är mer sjukskrivna än män på en mansdominerad arbetsplats.2015Independent thesis Advanced level (degree of Master (Two Years)), 80 credits / 120 HE creditsStudent thesis
    Abstract [sv]

    Syftet med studien är att från ett genusperspektiv bidra med kunskap om varför kvinnor är mer sjukfrånvarande än män inom ett industriföretag. Studien baseras på kvalitativa intervjuer med chefer, resurspersoner samt sjukskrivna kvonnor och män. Med utgångspunkt i forskning om sjukfrånvaro och ett doing gender- perspektiv analyseras varför kvinnor är mer sjukskrivna än män inom företaget. Resultatet visar att det finns flera förklaringar till kvinnors högre sjukfrånvaro inom företaget. Det är höga krav generellt sett på medarbetarna och kvinnor måste prestera bättre än männen inom företaget. Kvinnorna tar ett större ansvar för hem och familj, vilket gör att deras totala belastning både i arbetet och i övriga livet är högre än männens, vilket kan vara en förklaring till deras högre sjukfrånvaro inom företaget. Slutsatsen som dras av resultatet i studien är att hur kön skapas påverkar kvinnors arbetsförmåga och därigenom deras sjukfrånvaro. Hur kön skapas är beroende av normer i samhället och inom företaget.

    Design and Implementation of NFC-based gym mobile app2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This report investigates the technical and economic viability of introducing a Near Field Communication (NFC) client system in a gym environment. The system aims to aid the customers with logging their workout, retrieving information regarding exercises as well as enhancing the attendance control for both staff and customers. To identify what information to be presented, the most important quality factors and what functionalities are most desired, an exploratory case study was conducted. The study showed that there is a discrepancy between the desire to log ones workout and actually doing it. Most people want to keep track of how they workout, but despite the wide variety of workout applications on the market, they choose not to use them. The main concern expressed was that the logging needs to be fast and easy, indicating that the existing apps do not fulfill the ease of use desired. The system presented in this report is coupled to the gym where NFC tags pair an exercise to its corresponding logger and information in the application. The ability for the gym to track its customers’ workout habits is a rare feature that provides several economic benefits such as targeted advertisement, better maintenance control and new customer services analyzing their workout. For the system to be effective the customers need to use the system and log their workout, therefore it needs to be supported by the major mobile platforms. To accommodate this a hybrid platform approach using PhoneGap was used. This approach allows for development in one language that translates into native embedded web applications. At the time of writing Apple’s latest models do include the hardware for NFC communication. However, it is not possible to develop a custom NFC application for iPhone yet. By adopting the hybrid approach there is no need to create a whole new app when they do release the rights to do so. In conclusion, the technical viability of the NFC based system comes with the tradeoffs of dealing with the lack of standards of a new technology and being early on the market with a new feature. This calls for some custom solutions, since each platform adopts their own way of NFC implementation, but is manageable. The economic aspects are tied to the use of the system where the ease of use is the key factor for the customers. The end user tests indicate that NFC provides that small advantage over traditional workout applications needed to make logging attractive.

    Effect of oral IQoro(R) and palatal plate training in post-stroke, four-quadrant facial dysfunction and dysphagia: A comparison study2015In: Acta Oto-Laryngologica, ISSN 0001-6489, E-ISSN 1651-2251, Vol. 135, no 9, 962-968 p.Article in journal (Refereed)
    Abstract [en]

    Conclusion: Training with either a palatal plate (PP) or an oral IQoro(R) screen (IQS) in patients with longstanding facial dysfunction and dysphagia after stroke can significantly improve facial activity (FA) in all four facial quadrants as well as swallowing capacity (SC). Improvements remained at late follow-up. The training modalities did not significantly differ in ameliorating facial dysfunction and dysphagia in these patients. However, IQS training has practical and economic advantages over PP training. Objectives: This study compared PP and oral IQS training in terms of (i) effect on four-quadrant facial dysfunction and dysphagia after a first-ever stroke, and (ii) whether the training effect persisted at late follow-up. Methods: Patients were included during two periods; 13 patients in 2005-2008 trained with a PP, while 18 patients in 2009-2012 trained with an IQS. Four-quadrant facial dysfunction was assessed with an FA test and swallowing dysfunction with a SC test: before and after a 3-month training period and at late follow-up. FA and SC significantly improved (p less than 0.001) in both groups. FA test scores after training and at late follow-up did not differ significantly between the groups, irrespective of whether the interval between stroke incidence and the start of training was long or short.

    Digitala spel och dyslexi2015Independent thesis Basic level (degree of Bachelor), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    In the modern world there is a great emphasis on the individuals ability to partake in written information; however, as there is between 5% and 8% of the Swedish population that suffers from a learning disability, this can quickly become a problem. The fact that Dyslexia is hard to detect early on adds to the burden of those affected and can even lead to low self-esteem and failing motivation to study.

     

    Therefore, there is a need for new screening tools that can detect dyslexia early, an idea centered on a game for such a tool is what this study has chosen to focus on. The viability of such a game has been tried through a series of 16 qualitative interviews and 15 benchmarking analyses. The author makes the case for the requirement specification such a game based screening tool will have, what must be considered in its development, and how kids reflect upon games.

     

    The requirement specification presented in the results serves not only as a basis for a screening tool but also gives valuable insight into the opinions of children on the topic of gaming and provides the more practical suggestions for the tool itself.

    Impacts of Living and Working Conditions on the Health of Immigrants: A Comparative Study on Asylum-Seekers in Germany and the Netherlands2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    During the last several decades, many people, fleeing from disasters or political threats, have applied for asylum in the European countries. Council Directive 2003/9/EC, laying down minimum standards for the reception of asylum-seekers, as well as several other directives, have been developed in the EU in order to ensure fair treatment of the asylum-seekers in all the European countries. However, there are huge differences in the national asylum laws of countries and consequently, the way they treat the asylum-seekers. In this research, the national asylum laws of Germany and the Netherlands are studied and compared, showing that though following the Council Directive, fair or equal treatment of asylum-seekers cannot be guaranteed. In the Netherlands asylum-seekers are granted with a great extent of benefits while in Germany, they are greatly discriminated against. Based on the Social Determinants of Health Model, developed by Dahlgren and Whitehead in 1991, the hypothesis is that the asylum seekers in the Netherlands enjoy better health status than the ones in Germany, because based on the Dutch asylum laws, they have better living and working conditions. In order to confirm or negate this hypothesis, a meta-study of available literature on the health status of asylum-seekers has been done. However, the hypothesis could not be confirmed/ negated due to extreme lack of availability of data in this area.

    By discussing the relationship between life conditions and health of individuals, reviewing current legal instruments regulating asylum in the EU and analyzing the available data on the health status of asylum-seekers, this paper draws the attention to the importance of data and research on these topics and the need for development of practices for collection of such information. Availability of such information can affect future decision and policy makings regarding asylum-seekers and their health and might result in comprehensive reformations in the current national or international legal instruments.

    A Matter of Form: investigating a theory of design through a bench concept2015Independent thesis Basic level (degree of Bachelor), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    The report explains my Bachelor thesis, a bench system for public spaces. The work was done in collaboration with Lammhults möbel AB. The examproject is a journey that describes my designprocess which was guided by a very detailed briefing. The report describes my work that was very closely linked with the Lammhults product development team and the challenge was to design a commercial product that can be put into production. Another part of my degreeproject was to do form studies. The form study I did through formexperiments mixed with formtheory. In the experiments, I used my final shape of the bench as a bas. The formstudies is done to gain my deeper knowledge and understanding of the form field. This will work as a base to my more theoretical and analytical part of analyze form. My cooperation with Lammhults extends for a year, so probability risk is that the prototype I will show here unfortunately, not are the final productionready prototype.

    Force Majeure: Utvecklingen av begreppets innebörd och användningsområde inom köprätten2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Force majeure kan åberopas som ansvarsbefriande grund när något oförutsett och extraordinärt inträffar, vilket gör att en säljare inte kan fullgöra sin del av avtalet i tid.Begreppet är dock otydligt definierat i såväl lagtext som doktrin. Detta gör att förståelsen fördess användningsområde och tillämplighet är begränsad. På grund av att KöpL är dispositiv kommer force majeure idag oftast till uttryck genom friskrivningsklausuler i standardavtal. Som ett resultat av begreppets oklara innebörd utformas klausulerna på olika sätt, beroende på vilka som är parter, och ger därmed uttryck för olika situationer och omständigheter som kan ligga till grund för skadeståndsfrihet. Friskrivningsklausuler av typen force majeure har blivit allt vanligare, vilket tyder på att begreppet har börjat användas i en vidare utsträckning. Frågan blir således om det är rättssäkert och förutsebart att en part i avtalet ensam ges rätten att tolka huruvida det rör sig om force majeure?

    I uppsatsen undersöker vi hur begreppet force majeure har utvecklats från gamla till nya KöpL, samt hur force majeure används inom standardavtalsrätten som ansvarsbefriande grund. Detta har inneburit att en grundläggande utredning av 24 § gamla KöpL och 27 § nya KöpL har genomförts. Vi har även valt att beröra internationell köprätt, i form av CISG, eftersom denna ligger till grund för den svenska lagstiftningen. Dessutom har förarbeten, doktrin och internetkällor behandlats.

    Mot bakgrund av denna avsaknad av vägledning finner vi det motiverat att begreppet force majeure definieras tydligare i lagtext. Förslagsvis kan detta ske genom en uppräkning av händelser, vilka kan åberopas såsom force majeure, samt att hänsyn tas till eiusidem generis vid bedömningen. Detta innebär att de situationer som uppstår ska ha något gemensamt med de som räknas upp i paragrafen för att kunna leda till ansvarsfrihet. Ges begreppet en tydligare definition kan rättssäkerheten öka och därmed också ge avtalsparterna en ökad förståelse för vilka omständigheter som kan ligga till grund för ett åberopande av force majeure.

    Development of a forecast model for public transport trips in smaller cities2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    It has become more important for operators to be able to predict the future number of public transport passengers when consider to place a tender for operating public transport in a city or region, this is due to the new types of operator contracts was introduced quite recently. There are models in use today that can predict this, but they are often time consuming and complex and therefore it can be expensive to perform a forecast. Aside from this, most models in use for Sweden today are adapted for larger cities. Thus, the aim of this thesis is to propose a model that requires minimal input data with a short set up and execution time that can be used to predict a forecast for the public transport system in smaller cities without notably affecting the quality of the result. The developed model is based on a forecast model called LuTrans, which in turn is based on a common method, the four step model. The aim of the model lies within public transportation but it also consider other modes. The input data used by the model mainly consists of socio-economic data, the travel time and distance between all the zones in the network. The model also considers the cost for traveling by car or public transport. The developed model was applied to the Swedish city, Örebro, where a forecast was conducted for a future scenario. It is easily to apply the model to different cities to estimate a forecast for the public transport system. The developed model for the base scenario predicts trips for individual bus lines with an accuracy of 85 % for the city of Örebro. The developed model gave the result that the trips made by public transport in the future scenario of Örebro 2025 will increase annually by 0.94 %. The conclusion is that it is possible to develop a simple model that can be easily applied for a desired city. Although the developed model produced a plausible result for Örebro, further work such as implementation on other cities are required in order to fully evaluate the developed model.
