    Increased gross profits fromintangible and tangible assets: From a modular product’s perspective2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The world and its economy is going through countless and significant changes. Intangible assets are one of these changes due to the economy and the society have a higher demand for information than before. Nevertheless, tangible assets are still important assets within the economy since no economy will function without tangible assets. Intangible assets and tangible assets can contribute to that a business is gaining competitive advantages and thereby, increasing the level of profits.

    The focal study has been performed at Sweco Environment AB and aims to investigate how intangible assets and tangible assets contribute to increased gross profits within a specific service industry, where a modular product can be implemented. A modular product wasinvestigated in order to find differences and similarities which can affect a business’ opportunities to generate increased gross profit. The focal study is limited to a modular product and a specific industry, where it can be applied. In order to perform the focal study, scientific articles, books and reports have been utilised to form a foundation of the theoretical framework. The theoretical framework consists of sustainability, modularity and economics. Subsequently, a combination of a qualitative and quantitative research has been conducted. The qualitative research included observations and semi-structured interviews with experienced participants within the field. The quantitative research contained archival records with annual financial statements and balance sheets of private corporations within the Swedish market. The archival records were used in order to perform the econometric analysis.

    The results from the observations and interviews demonstrated a holistic picture of the nonmodular product and the modular product. The main differences were found within the process from customer order to utilisation and the leasing option for the modular product. The econometric analysis which was performed in the specific service industry indicated that tangible assets were not statistically significant meanwhile, intangible assets were statistically significant. A 1 % increase in intangible assets contribute to 0.088 % increase in gross profit per employee. By investing in intangible assets does not only contribute to increased gross profits, it can also lead to competitive advantages.

    På jakt efter det erfarna landskapet: skillnader mellan hur landskap konstrueras när det kroppsligen erfars och hur det konstrueras i planeringens styrdokument2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna uppsats handlar om landskap och planering, mer bestämt om olika landskapssyner och hur de återspeglas i planeringens beslutsunderlag. Planerare och medborgare tenderar att värdera landskap och platser olika. Enligt landskapskonventionen ska landskapsanalys genomföras av både medborgare och expertgrupper för att skapa en övergripande bild över hur landskap betraktas och värderas (Europarådet, 2008:31). Från landskapskonventionen (Europarådet, 2008:43) ställs krav på att alla synsätt av vad landskap är ska inkluderas i landskapsplanering. Vilket i sin tur ställer krav på planeringen att hitta metoder som kan identifiera dessa olika synsätt. Denna uppsats syftar till att undersöka olika idéer om vad landskap är och kan vara, och hur dessa kan återspeglas i planeringens beslutsunderlag. Genom sammansättning av lämpliga metoder har vi utformat en landskapsvandring med syfte att ta reda på hur landskap konstrueras när det erfars. Vandringen har genomförts med planerare i Simrishamn kommun och intervjuer därifrån utgör en del av det empiriska materialet. Den andra delen utgörs av en dokumentstudie av styrdokument från Simrishamns kommun och Skåne länsstyrelse med syfte att undersöka hur landskap konstrueras i planeringsdokument.I tidigare forskning inom området framgår att landskapet präglas av pluralitet och att det därför inte finns en entydig bild av vad landskap är och hur det ska beaktas i landskapsplanering (Butler, 2014:13). Genom att undersöka hur planerare konstruerar landskap i tal och skrift ska vi försöka identifiera idéer om landskap som bör återspeglas i landskapsplaneringen. I uppsatsens analysdel diskuteras det empiriska materialet och kategoriseras utifrån forskningslägets identifierade spänningar angående de olika sätt som landskap konstrueras. Vidare svarar vi på uppsatsens frågeställning angående hur landskap konstrueras när det erfars och i planeringens styrdokument.

    Elektriskt drivsystem för tandemvält: En utvecklingsprocess2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    I dagens samhälle har det blivit mer och mer populärt med miljövänliga lösningar. Inom detta område har fordonsindustrin utmärkt sig de senaste åren genom utvecklandet av eldrivna bilar. Därför börjar även företagen som utvecklar tunga maskiner bli intresserade av att börja utveckla mer miljövänliga produkter.

     

    Syftet med arbetet som vi utfört i samarbete med Dynapac Compaction Equipment AB i Karlskrona har varit att utveckla ett koncept till en lösning av ett miljövänligt drivsystem för deras minsta tandemvält. Det är tänkt att motsvara den vardagliga prestationen av det dieseldrivna systemet, utan att bli för dyrt, samt undvika att använda specialbeställda produkter.

    Dental status in nursing home residents with domiciliary dental care in Sweden2017In: Community Dental Health, ISSN 0265-539X, Vol. 34, no 4, p. 203-207Article in journal (Refereed)
    Abstract [en]

    Objective: To describe the dental health status of elderly people in nursing homes receiving domiciliary dental care. Design: Case note review. Clinical setting: Nursing homes in 8 Swedish counties. Participants: Care dependent elderly people (>= 65 years). Methods: Clinical data, including the number of remaining natural teeth, missing and decayed teeth (manifest dental caries) and root remnants, recorded by dentists according to standard practices. Medical and dental risk assessments were performed. Results: Data were available for 20,664 patients. Most were women (69.1%), with a mean age of 87.1 years (SD 7.42, range 65-109). The mean age for men was 83.5 years (SD 8.12, range 65-105). Two or more medical conditions were present in most of the population. A total of 16,210 individuals had existing teeth of whom 10,974 (67.7%) had manifest caries. The mean number of teeth with caries was 5.0 (SD 5.93) corresponding to 22.8% of existing teeth. One in four individuals were considered to have a very high risk in at least one professional dental risk assessment category. Conclusions: Care dependent elderly in nursing homes have very poor oral health. There is a need to focus on the oral health-related quality of life for this group of frail elderly during their final period of life.

    Äldreomsorg och motivation: En kvantitativ studie om motivationsfaktorer och anställningsformer2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Med hjälp av en enkät undersöktes studiens huvudsyfte för att ta reda på vilka faktorer som anses viktiga för motivation och arbetstillfredsställelse på arbetet och vidare se skillnad mellan timanställd och tillsvidare anställd personal inom äldreomsorgen. Deltagandet resulterade 39 ifyllda enkäter från undersköterskor och vårdpersonal. Resultatet visade att det skiljer sig åt vad man anser vara motiverade i relation till anställningsform. Studien hittade indikationer som tyder på att tillsvidare anställd personal anser att hygien faktorer och yttre motivation är viktiga. Timanställd personal anser att inre motivation och motivationsfaktorer är viktiga. Lönen var den viktigaste faktorn enligt tillsvidare anställd personal och timanställd personal ansåg att det viktigaste var att komma hem och känna att man gjort någonting bra för patienten.

    Realistic Package Opening Simulations: An Experimental Mechanics and Physics Based Approach2015Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    A finite element modeling strategy targeting package opening simulations is the final goal with this work. The developed simulation model will be used to proactively predict the opening compatibility early in the development process of a new opening device and/or a new packaging material. To be able to create such a model, the focus is to develop a combined and integrated physical/virtual test procedure for mechanical characterization and calibration of thin packaging materials. Furthermore, the governing mechanical properties of the materials involved in the opening performance needs to be identified and quantified with experiments. Different experimental techniques complemented with video recording equipment were refined and utilized during the course of work. An automatic or semi-automatic material model parameter identification process involving video capturing of the deformation process and inverse modeling is proposed for the different packaging material layers. Both an accurate continuum model and a damage material model, used in the simulation model, were translated and extracted from the experimental test results. The results presented show that it is possible to select constitutive material models in conjunction with continuum material damage models, adequately predicting the mechanical behavior of intended failure in thin laminated packaging materials. A thorough material mechanics understanding of individual material layers evolution of microstructure and the micro mechanisms involved in the deformation process is essential for appropriate selection of numerical material models. Finally, with a slight modification of already available techniques and functionalities in the commercial finite element software AbaqusTM it was possible to build the suitable simulation model. To build a realistic simulation model an accurate description of the geometrical features is important. Therefore, advancements within the experimental visualization techniques utilizing a combination of video recording, photoelasticity and Scanning Electron Microscopy (SEM) of the micro structure have enabled extraction of geometries and additional information from ordinary standard experimental tests. Finally, a comparison of the experimental opening and the virtual opening, showed a good correlation with the developed finite element modeling technique. The advantage with the developed modeling approach is that it is possible to modify the material composition of the laminate. Individual material layers can be altered and the mechanical properties, thickness or geometrical shape can be changed. Furthermore, the model is flexible and a new opening device i.e. geometry and load case can easily be adopted in the simulation model. Therefore, this type of simulation model is a useful tool and can be used for decision support early in the concept selection of development projects.

    Advancements in package opening simulations2014In: Procedia Materials Science / [ed] Zhang, Z; Skallerud, B; Thaulow, C; Ostby, E; He, J, Elsevier, 2014, Vol. 3, p. 1441-1446Conference paper (Refereed)
    Abstract [en]

    The fracture mechanical phenomenon occurring during the opening of a beverage package is rather complex to simulate. Reliable and calibrated numerical material models describing thin layers of packaging materials are needed. Selection of appropriate constitutive models for the continuum material models and how to address the progressive damage modeling in various loading scenarios is also of great importance. The inverse modeling technique combined with video recording of the involved deformation mechanisms is utilized for identification of the material parameters. Large deformation, anisotropic non-linear material behavior, adhesion and fracture mechanics are all identified effects that are needed to be included in the virtual opening model. The results presented in this paper shows that it is possible to select material models in conjunction with continuum material damage models, adequately predicting the mechanical behavior of failure in thin laminated packaging materials. Already available techniques and functionalities in the commercial finite element software Abaqus are used. Furthermore, accurate descriptions of the included geometrical features are important. Advancements have therefore also been made within the experimental techniques utilizing a combination of microCT-scan, SEM and photoelasticity enabling extraction of geometries and additional information from ordinary experimental tests and broken specimens. Finally, comparison of the experimental opening and the virtual opening, showed a good correlation with the developed finite element modeling technique.

    Simulation of thin aluminium-foil in the packaging industry2017In: AIP Conference Proceedings / [ed] Brabazon D.,Ul Ahad I.,Naher S., American Institute of Physics Inc. , 2017, Vol. 1896, article id 160014Conference paper (Refereed)
    Abstract [en]

    This work present an approach of how to account for the anisotropic mechanical material behaviour in the simulation models of the thin aluminium foil layer (≈10 μm) used in the Packaging Industry. Furthermore, the experimental results from uniaxial tensile tests are parameterised into an analytical expression and the slope of the hardening subsequently extended way beyond the experimental data points. This in order to accommodate the locally high stresses present in the experiments at the neck formation. An analytical expression, denominated Ramberg-Osgood, is used to describe the non-linear mechanical behaviour. Moreover it is possible with a direct method to translate the experimental uniaxial tensile test results into useful numerical material model parameters in Abaqus™. In addition to this the extended material behaviour including the plastic flow i.e. hardening, valid after onset of localisation, the described procedure can also capture the microscopic events, i.e. geometrical thinning, ongoing in the deformation of the aluminium foil. This method has earlier successfully been applied by Petri Mäkelä for paperboard material [1]. The engineering sound and parameterised description of the mechanical material behaviour facilitates an efficient categorisation of different aluminium foil alloys and aid the identification of the correct anisotropic (RD/TD/45°) mechanical material behaviour derived from the physical testing. © 2017 Author(s).

    How firms can reduce the risks with fixed price contracts2017Independent thesis Advanced level (degree of Master (One Year)), 300 HE creditsStudent thesis
    Abstract [en]

    Firms have had difficulties in dealing with the risks that occur when providing fixed price contracts (FP) for both small – scale and large – scale projects to involved customers. This is general for the most companies surveying customers with the development for a product or service in the IT – industry. Research has paid minimum attention on how firms can imple-ment scientific proven agile methods to reduce the risks with FP contracts to increase profit margin. In FP contracts, the risks lie on the supplier providing the contract, where research has shown that companies have issues in determining the project scope in the planning pro-cess and how they can find certain approaches for increasing the dialogue in a buyer and seller arrangement. Therefore, firms are more comfortable in going into Time and Material (T&M) arrangements where customers pay for the time and resources spent under a project process. This study also makes investigations on how firms can make accurate estimations of the development durations that occurs when providing this contracting form and how firms can identify risks into profitable pricing engagements. The study took ground in Lund, Swe-den at a company named Sigma Connectivity which is a firm developing services and prod-ucts based on wireless communication and the phenomenon called Internet Of Things (IoT).The delimitations that were made for this study was related to the marketing mix concept which conducts of seven strategies for business management of these seven strategies the choice was made to exclude exclude sustainable aspects, physical evidence, internal market-ing related to promotion, and location factors. Internal qualitative directive and semi – struc-tured interviews were methods used for determining variables and key issue with FP contracts that was included in the survey based approach to customers. Agile methods such as Feature Driven Development (FDD) and Work Breakdown Structure (WBS) were implemented in or-der to tackle the challenges of visualising a clear project scope description with clear specifi-cation on what is included in a FP contracts in small – scale and large – scale projects.The results conducted from this study shows that integrating scientific proven methods such as FDD and WBS in a firm, will help them to divide project processes into smaller mecha-nisms, which will provide sufficient access for an increased project scope allocation forcing the involved parties in a buyer and seller arrangement to hold both internal and external re-views which will enable the possibility of making pricing approaches during the project pro-cess. Results also shows that customers find FP contracts to be the most valuable but the diffi-culties that they have felt in this arrangement is to incorporate new ideas for a project scope change during a project process. The use of the FDD framework and WBS provided results that are vital for firms going into FP arrangements where clearer project scope definitions, key role identifications, increased pricing opportunities and communication channels were founded.Keywords: Fixed price contracts (FP), project scope, Work Breakdown Structure (WBS), Feature Driven development (FDD).

    Quality Assessment for HEVC Encoded Videos: Study of Transmission and Encoding Errors2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    There is a demand for video quality measurements in modern video applications specifically in wireless and mobile communication. In real time video streaming it is experienced that the quality of video becomes low due to different factors such as encoder and transmission errors. HEVC/H.265 is considered as one of the promising codecs for compression of ultra-high definition videos. In this research, full reference based video quality assessment is performed. The raw format reference videos have been taken from Texas database to make test videos data set. The videos are encoded using HM9 reference software in HEVC format. Encoding errors has been set during the encoding process by adjusting the QP values. To introduce packet loss in the video, the real-time environment has been created. Videos are sent from one system to another system over UDP protocol in NETCAT software. Packet loss is induced with different packet loss ratios into the video using NETEM software. After the compilation of video data set, to assess the video quality two kind of analysis has been performed on them. Subjective analysis has been carried on different human subjects. Objective analysis has been achieved by applying five quality matrices PSNR, SSIM, UIQI, VFI and VSNR. The comparison is conducted on the objective measurement scores with the subjective and in the end results deduce from classical correlation methods.

    SAMSPEL OCH LÄSFÖRSTÅELSE- Lärares upplevelser av samspel med lässvaga elever.2015Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    The purpose of my research was to develop new knowledge about teachers' experiences of interaction between teachers and students with weak reading comprehension and how these teachers feel that the phenomenon of interaction is expressed in a school context. A focus-group interview with four teachers who have been employed between 4-25 years have been conducted with a hermeneutic research approach as a basis for understanding teachers' perceptions of the phenomenon of interaction. The results suggest that the interaction and communication is an important part of the work. In the communication and interaction results show that concepts such as dialogue, development , understanding and rhetoric are tools that teachers work with in order to develop a better reading comprehension for students.

    Organizations as Functioning Social Systems: A Review of Social Sustainability in Management and Organizational Research2014Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    One of the reasons, why it is difficult to implement the concept of social sustainability into organizations, is its inherent complexity and vagueness. The new Social Sustainability Principles (SSPs) within the Framework for Strategic Sustainable Development (FSSD) offer a clear definition of success for the social system. This study aims to put the new SSPs into an organizational context. It investigates how people-related issues within organizations, discussed in six organizational and management journals, published between 2009 and 2014, are related to the SSPs. One fourth of the 3305 reviewed articles were found to relate to social sustainability. Most of the articles focused on improving performance through aspects related to social sustainability. The articles mainly discussed aspects related to barriers to the SSPs as problems, solutions or positive aspects that could remove barriers to the SSPs. The results show that for organizational research to be able to support organizations moving towards social sustainability, there is a need for a clear definition of success as well as a frame that takes the whole social system into consideration. The FSSD and the SSPs could help to structure the diverse topics, put research problems in a bigger context and discern relevant problems and solutions.

    The Attitudes of Christian Church Pastors and Leaders toward Leadership Succession, For Leadership Continuity, in Charismatic and Pentecostal Church Organizations in Kumasi, Ghana.2015Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Lack of cooperation of the incumbent leaders was a major cause of leadership succession failures of organizations reported. This investigation was carried out to determine the attitudes of Christian Senior Pastors and leaders (associate Pastors and Elders), for leadership continuity, toward leadership succession of Charismatic and Pentecostal Church organizations in Kumasi, Ghana; to find lasting solution to the problem of lack of cooperation of incumbent leaders towards leadership succession planning by determining the root cause of lack of cooperation of incumbent senior leader towards leadership succession. Using in-depth interview, qualitative data was collected and analyzed using inductive procedure of Structuring (Ordering) of Meanings Using Narrative for analysis. This work contends that even though best practices are necessary condition for leadership succession effectiveness, they are not sufficient to make the incumbent senior leader willing and cooperative enough to act in the best interest of the organization, let alone yield to leadership succession. It was found that the Christian Churches investigated have positive attitudes towards leadership succession because of character development adopted in the churches. It was found that apart from fear (Freeman, 2004; Zhang and Rajagopalan, 2006; 2010) and ego (Freeman, 2004; Beeson, 2006; Ciampa, 2005), unforgveness and self-centeredness were other causes, holding back the effectiveness of leadership succession due to lack of cooperation of the incumbents, with self-centeredness being the source of fear, ego and unforgiveness. It was concluded that self-centeredness was the root cause of lack of cooperation of Senior Pastors towards leadership succession. Because fear (Freeman, 2004; Zhang and Rajagopalan, 2006; 2010), ego (Freeman, 2004; Beeson, 2006; Ciampa, 2005), unforgiveness and self-centeredness produce insecurity, the incumbents were never willing and cooperative to subject themselves to anything they perceived as threat. On the basis of this, succession failures reported will rather increase in frequency. Nevertheless, self-centeredness could be resolved effectively by adopting character development focused on the following nine attributes: Faith, Peace, Joy, Humility, Patience, Self-control, Kindness, Goodness and Love (value, respect, approval, availability, attention, appreciation and service).The results suggest that the incumbent Pastors have the tendency to take actions, make choices and decisions that are in the best interest of their organization, and are favorably disposed towards leadership succession. The Christian Churches are well positioned to produce leaders who are cooperative and selfless enough to plan their own succession using best practices that yield desired outcomes. This work contributes to a better understanding of attitudes, character, relationship, motivation, highlights the invisible features (self-centeredness, fear, ego and unforgiveness) of leadership succession failures in the organization, and the transformation of character that results by simple change of attitudes consistently modified by love and its attributes so that the decisions, choices and actions of the incumbents can favor the organization, consequently, making them willing and cooperative enough to plan their own succession. Based on the results of the Christian Church organization, it serves as a basis for further research in the field.

    Intelligent Beam Weight Computation for Massive Beamforming2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    LTE (Long Term Evolution) is likely the most complex wireless system ever developed. It incorporates features that could not have been economically implemented as recently as a decade ago. Today, with large-scale ICs, LTE can be easily accommodated in base stations and battery-powered handsets alike. LTE-Advanced is the upgraded version of LTE technology for providing more speed and greater reliability.

    In this report, the wireless communication between the user and base station is implemented by creating 4G LTE environment in MATLAB. Impact of Coherence time on beam weight computation varies for different delay profiles. Moreover, SNR of the transmitted signal varies significantly by the time gap between two successive uplink frames in TDD configuration. In this report, computationally efficient algorithm for reducing beam weight computations in system level LTE simulations is proposed.

    The wireless channel is modelled in both Rician and Rayleigh fading channel. Efficiency of beam forming algorithms is observed at different channel conditions like delay profile, fading channel, bandwidth, correlation, modulation technique.

    The MUSIC algorithm is implemented for detecting the movement of the users in Line of sight condition

    Transitioning towards Sustainability: What are we waiting for?2018Independent thesis Advanced level (degree of Master (One Year)), 20 HE creditsStudent thesis
    Abstract [en]

    There is growing consensus that humanity is being confronted with a sustainability challenge of which the severity has never been known to modern man. This pressing situation is demanding solutions and alternatives to change the path of society. At the community level, grassroots movements have emerged around the world as a way of striving to develop local sustainability.  This research studies the Transition Movement, a popular, global community-based movement. The aim of this study is to evaluate if a Transition Initiative is effective in moving a local community towards sustainability. The definition of sustainability used in the research is taken from the Framework for Strategic Sustainable Development (FSSD) which comprises of eight sustainability principles (SPs); three ecological SPs and five social SPs. To this end, an analytical-evaluative case study of a single Transition Initiative was conducted in which semi-structured interviews, a survey and document analysis were all use as sources of information. The researchers chose a small-scale Transition Initiative, conducting the case study on the village of Ungersheim, France. The results revealed that the actions of Transition are contributing to progressing Ungersheim towards sustainability, both socially and ecologically. The research also revealed how the Transition is being done and what critical factors allowed for success. The study finally deduces a set of strategic guidelines that may be used for further longitudinal research cross-evaluating Ungersheim to other small-scale community transitions.

    Exploring Holacracy’s Influence on Social Sustainability Through the Lens of Adaptive Capacity2016Independent thesis Advanced level (degree of Master (One Year)), 20 HE creditsStudent thesis
    Abstract [en]

    The organizational structure of Holacracy has been gaining popularity in recent years,

    but a lack of academic research on Holacracy called for a systematic approach to assessing its

    merits and shortcomings. The need Holacracy fills, is that of organizations dealing with a

    complex world and rapidly evolving technology. While Holacracy is not tailored to address

    sustainability issues, there are many components that made it a candidate for the researchers to

    examine it through a social sustainability lens.

    This study examines the effect of specific components of Holacracy with elements of adaptive

    capacity – a theory from which the research definition of social sustainability was built. With

    the goal of determining the effect of Holacracy on social sustainability, a questionnaire directed

    at employees and practitioners of holacratic organizations was utilized.

    The findings implied that Holacracy does positively influence the experience of the elements

    of adaptive capacity; with the relationship to the adaptive capacity element of self-organization

    being a standout. The importance of trust is also identified. The link to the Framework for

    Strategic Sustainable Development can be elucidated through adaptive capacity’s influence to

    the social sustainability principles. Because of the importance of social sustainability and social

    capital to organizational performance and longevity, this research is of value to any business

    using, or considering using Holacracy.

    A teacher training workshop to promote the use of the VISIR remote laboratory for electrical circuits teaching2017In: Proceedings of 2017 4th Experiment at International Conference: Online Experimentation, exp.at 2017, Institute of Electrical and Electronics Engineers Inc. , 2017, p. 1-6Conference paper (Refereed)
    Abstract [en]

    The learning of Physics involves building up and using lab experiments. In turn, teachers must be trained in experimenting and using several resources that enable them to design valuable teaching strategies and learning activities. Thanks to Information and Communication Technologies (ICT), virtual and remote labs can provide a framework where physical experiments can be developed. Altough remote labs have been in use for over a decade now in several countries and levels of education, its use at secondary schools in Latin America has not been reported yet. The Virtual Instruments System in Reality (VISIR) is one of these remote labs, suitable to practice in the area of electrical circuits. This paper aims at describing how this remote lab was used in a training workshop for secondary school level teachers of Physics in Costa Rica. © 2017 IEEE.

    Fotbollens språk-en diskursanalys av journalisters och supportrars sätt att tala om Parken-skandalen2014Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Syftet med uppsatsen är för det första att genom diskursanalys analysera hur supportrar till fotbollslaget Malmö FF på Himmelriket på Svenskafans framställer diskurser kring läktarbråket i Parken år 2005 samt hur Sydsvenskan framställer samma läktarbråk utifrån samma incident och tidpunkt. För det andra syftar uppsatsen till att klarlägga de eventuella diskursernas relation till omliggande sociala strukturer som enligt Fairclough antingen påverkar diskurserna eller själv blir påverkad av diskurserna. De två forskningsfrågorna är således, vilka diskurser som kan identifieras kring Parkenskandalen hos supportrar på Svenskafans och hos Sydsvenskan? Samt, Vilken relation finns det mellan diskurserna och omliggande sociala strukturer? Uppsatsen har i bakgrundsavsnittet gått igenom supporterskap ur MFF-supports perspektiv, även huliganism ur ett vetenskapligt perspektiv för att skapa förståelse kring skillnader på supportrar och huliganer, vidare återges medias bevakning av andra incidenter samt annan fotbollsrelaterad forskning som är tänkt att utgöra förförståelse för problemområdet. Som tidigare forskning har författaren valt att använda sig av avhandlingen ”Kung Fotboll” av Thorbjörn Andersson vars verk bygger på en engelsk och nordisk kontext kring fotbollsrelaterade fenomen förr i tiden och där publikbråken under denna tid analyserats. Metoden som används i kandidatuppsatsen för dels bearbetning av empiri samt för att svara på de två forskningsfrågorna består av Faircloughs kritiska diskursanalys. Faircloughs kritiska diskursanalys har sedan även används som teoretisk utgångspunkt tillsammans med Foucaults teori om utestängningssystem. Foucaults socialkonstruktivistiska perspektiv utgör även en bakgrundsförklaring till kandidatuppsatsens genomgång av Faircloughs kritiska diskursanalys. Det empiriska materialet utgörs av 15 artiklar från Sydsvenskan.se samt 9 publicerade artiklar av supportrar på svenskafans.com som valts ut i en analytisk process där fokuset är hur supportrarna och journalisterna beskriver ordningsvakternas och polisernas beteende och utseende. I resultat och analys som görs på tre olika nivåer, textanalys, diskursiv analys samt analys av den bredare sociala praktiken, visar författaren att journalisternas diskurs skiljer sig från supportrarnas diskurs och att det därför föreligger en låg grad av samhällelig förändring i den omliggande sociala strukturen. Journalisterna använder en diskurs som har mindre negativa konnotationer kring utseende och beteende hos ordningsvakter och polis än den diskurs som supportrarna använder och därtill fokuserar journalisterna mer på enskilda isolerade fall medan supportrarna oftare återger beskrivningar som inte enbart återger isolerade händelser. Därefter ges det en tänkbar förklaring utefter Foucaults teori om utestängningssystem till varför relationen mellan diskurserna och den omliggande sociala strukturen ser ut som den gör. I den slutliga diskussionen gör författaren reflektioner kring metoden samt ger en återkoppling till tidigare forskning och menar att resultaten i kandidatuppsatsen kan utgöra fördjupad förståelse kring hur media väljer att fokusera vid publikbråk.

    Lärande utvärdering i ESF-projektet Kompetens i vård och omsorg, KIVO. Slutrapport.2014Report (Other academic)
    Abstract [en]

    Projektet ”Kompetens i vård och omsorg”, KIVO är ett Europeiskt socialfondsprojekt (ESF) som genomfördes under tiden 2011-10-01 till 2013-09-30. Projektägare är Landstinget Blekinge och chefen för Blekinge kompetenscentrum är projektägarens ombud. Inom projektet finns samarbetsavtal mellan Landstinget Blekinge, Äldre förvaltningen, Karlskrona kommun och Hälsohuset för alla AB. Den totala projektbudgeten var 8749 920 SEK.1 KIVO är ett tvåårigt projekt som har haft en lång startsträcka. Det innebär att aktiviteterna inom projektet startade på allvar först i november 2012 och genomfördes under 11 månader. En förklaring är att flera inom nuvarande projektledningsgruppen började arbeta med projektet i slutet av år 2012 eller i början av år 2013. I föreliggande slutrapport redogörs för den lärande utvärdering som bedrivits inom KIVO under tiden 2013-01-01 och 2013-09-30. Syftet var att följa projektets arbete mot uppsatta mål. Centralt i den lärande utvärderingen har varit dialogen med projektledarna, projektledningsgruppen och projektägarens representant. Min roll har varit stödjande, men också störande under processen det vill säga ifrågasättande och kritisk. Rapporten är indelad i fem delar. Första delen beskriver bakgrunden till projektet, dess syfte och mål. I den andra delen presenteras metodologiska utgångspunkter för den lärande utvärderingen. Den tredje delen fokuserar på arbetet med hållbart lärande och hållbar jämställdhet. Analys och resultat av den lärande utvärderingen redovisas i del fyra. Slutligen i del fem förs ett framåtsyftande resonemang om vilka hållbara effekter som projektet bidragit med. Förhoppningen är att denna slutrapport kan bidra till reflektion och lärande kring förutsättningar för att ett projekt som KIVO ska uppnå långsiktiga effekter, samtidigt som den lyfter fram den faktiska måluppfyllelsen som projektet har uppnått.

    Anhörigas upplevelser av att vårda en person med palliativ diagnos i hemmet: En litteraturstudie2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Utvecklingen i Sverige går mot att fler personer med palliativ diagnos vårdas och dör i hemmet. Detta medför ofta att anhöriga får rollen som vårdare och att deras ansvar för den terminala vården i hemmet ökar. För att sjukvården ska kunna ge rätt stöd och adekvat information till anhöriga och personen med palliativ diagnos är det därför värdefullt att ta del av deras erfarenheter.

    Syfte: Syftet med studien var att beskriva anhörigas upplevelser av att vårda en person med palliativ diagnos i hemmet.

    Metod: Nio vetenskapliga artiklar med kvalitativ ansats granskades och bedömdes i en kvalitetsmodell. Den insamlade data analyserades med hjälp av innehållsanalys.

    Resultat: Analys av artiklarna utmynnade i tre huvudkategorier, Dagliga livet förändrades för båda parter, Sjukvården både hindrade och stöttade och Döden en del av vardagen. Innehållet i huvudkategorierna genererade de sex underkategorierna, Förändrade relationer, Det egna livet i andra hand, Att få hjälp och stöd, Att inte få hjälp och stöd, Rädsla för döden och Att leva i nuet. Ett övergripande tema, En förändrad livssituation sammanfattade tolkningen av de anhörigas upplevelser.  

    Slutsats: Anhöriga som vårdar personer med palliativ diagnos i hemmet behöver stöd och uppmärksammas av sjukvården. Deras egna behov kommer i andra hand eftersom de sätter personen med palliativ diagnos i första hand. De kan då känna sig isolerade och ensamma.

    PERFORMANCE EVALUATION OF VIDEO QUALITY ASSESSMENT METHODS BASED ON FRAME FREEZING2014Independent thesis Advanced level (degree of Master (Two Years))Student thesis
    Abstract [en]

    A Digital Video Communication System consists of a video encoder, a channel through which the video is transmitted and finally a video decoder. These three phases can cause different kinds of impairments or degradations in the quality of a video. One of the degradations that takes place due to an error prone channel is frame freezing and it affects the quality of a video. Frame freezing is a phenomenon in which a particular frame is repeated (displayed) for a certain period of time until the next correct frame is received hence producing a pause or a freeze in a video sequence. Frame freezing can be single or multiple depending on the channel characteristics. Research is being conducted in order to devise a metric which can help in quantifying a video sequence on the basis of its quality. Researchers design metrics and then using their mathematical models, they compare their results with subjective measurements. Subjective measurements help in telling the preciseness and correctness of the metric that whether the quality assessment metric is close enough to subjective test measurements. In this report, three metrics used for video quality assessment have been studied and compared mathematically as well as by careful experiments. The three metrics, chosen for this study, work on No Reference (NR) method for judging the quality of a video. Subjective tests have been performed keeping in view of the recommendations of ITU (International Telecommunication Union). After the study of these three metrics, their advantages and disadvantages over each other have been discussed and the metric that performs the best under certain conditions has been proposed. Finally, a conclusion has been made for the metric that performs the best and also for the metric that performs the worse or even does not perform at all under certain conditions.

    Anställdas uppfattning av arbetsplatslärande2014Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Den här studien utgår från en fenomenografisk ansats. Vi avser att fånga skilda uppfattningar om arbetsplatslärande och studera hur uppfattningarna påverkar medarbetarnas arbetstillfredsställelse. Vi utgick från två frågeställningar: vilka uppfattningar har medarbetare av hur de lär på sin arbetsplats, och finns det skillnader i medarbetarnas uppfattningar av vad de lär? Resultatet visar att deltagarnas uppfattningar om fenomenet skiljer sig åt. Tolkningen av resultatet visar att deltagarna lär på olika sätt och använder kunskapen olika i deras yrkesutförande. De lär genom erfarenhet, socialt samspel, teoretiskt samt genom praktiskt arbetsutförande. De utvecklar och lär flexibilitet, anpassning, problemlösning och socialt samspel. Det finns ett samband mellan hur deltagarna uppfattar fenomenet och arbetstillfredsställelse. När arbetsplatslärande är effektivt bidrar det på ett positivt sätt till deltagarnas arbetstillfredsställelse.

    Hur Anställda Erfar Självförmåga2015Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [en]

    Syftet var att öka förståelsen av hur fenomenet självförmåga erfars av anställda samt hur de föreställer sig sin respektive nivå av självförmåga. Banduras (1997) teori om självförmåga användes med fenomenografi som metod. Fyra anställda på olika organisationer och med olika ålder och kön intervjuades. Det uppfattades att självförmåga fanns i många olika aspekter av de anställdas yrkessliv, det uppfattades som något som påverkade dem i väldigt stor utsträckning. Deltagarna hade sinsemellan olika nivåer av självförmåga och det visades tydligt i hur de hanterade olika delar av sitt arbetsliv. Det visades i deras val av arbetsuppgifter och om de påverkades positivt eller negativt av omgivningen samt av sina erfarenheter. Fler fenomenografiska studier om självkänsla bör genomföras inom psykologin, det skulle vara intressant att koppla emotioner och personlighets tester till fenomenet.

    Material selection: A qualitative case study of five design consultancies2017In: Proceedings of the International Conference on Engineering Design, ICED, The Design Society, 2017, no DS87-1, p. 439-448, article id DS87-1Conference paper (Refereed)
    Abstract [en]

    This qualitative case study aims at understanding when and how industrial designers, working in design consultancies, engage in activities that will influence material selection in the design process. While the extant literature presents material selection processes as a sequence of activities aimed at finding candidate materials, there is paucity of research on material criteria activities. Formulating material criteria is an activity that is performed during all design phases and they become clearer and more complete throughout the project. For the case studies, explorative semi-structured interviews were conducted with five industrial designers with 10 years of work experience or more. The results suggest (a) that risk management has a major influence on the material selection process, (b) that negotiations of project boundaries in the 'fuzzy' pre-design phase has crucial influence on the risk management aspect of the material criteria activities, and (c) a lack of awareness that design briefs usually outline material criteria expressed as sensorial characteristics, which are later translated by engineering into final material criteria used for the material selection process.

    A shift from technical properties towards sensorial characteristics in product design education2017In: Proceedings of the 19th International Conference on Engineering and Product Design Education:: Building Community: Design Education for a Sustainable Future / [ed] Gulden T.,Pavel N.,Kovacevic A.,Buck L.,Bohemia E.,Berg A., Institution of Engineering Designers, The Design Society , 2017, p. 388-393Conference paper (Refereed)
    Abstract [en]

    The aim of this study is to evaluate a new pedagogic approach implemented in a compulsory materials course for product design students at bachelors level at ABC University. When developing a new curriculum for the material course, a decision was made to teach materials and production methods in a contextualized setting with emphasis on how students can deal with materials in a design process. Methods can be seen as mental tools that aid the design students in navigating complexity and offers them a structure to deal with unfamiliar territories. After an evaluation, some methods, guidelines and tools were selected to integrate in the compulsory materials course for the product design students, e.g. the Expressive-Sensorial Atlas [1], Meaning Driven Materials Selection [2] and the Material Driven Design method [3]. The implementation is made in two steps in order to test, evaluate and further develop a framework for teaching materials courses to product design students. The study evaluate the first step of implementation in general, and the implementation of the Material Driven Design method in particular. It is hoped that this research can contribute to further development of pedagogical approaches for teaching materials and production methods in a contextualized setting for product design students at bachelors level.

    KOMMUNIKATION OCH SAMARBETE: Upplevelser av förutsättningar för informellt lärande i olika arbetsmiljöer2014Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [en]

    Syftet med denna studie är att utveckla kunskap om medarbetarnas upplevelser av hur strukturen på den fysiska arbetsmiljön påverkar deras förutsättningar för det informella lärandet. Studien har en hermeneutisk ansats för att tolka och förstå medarbetarnas upplevelser. För att besvara vår forskningsfråga utfördes datainsamlingen i form av halvstrukturerade intervjuer med åtta medarbetare som arbetar inom samma organisation men i två olika arbetslag. Medarbetarna sitter och arbetar i olika strukturer av fysiska arbetsmiljöer. Resultatet av studien visar att arbetslaget som satt och arbetade i öppet kontorslandskap upplevde att de hade lättare för att kommunicera och samarbeta då de satt bredvid varandra och arbetade. Dock upplevdes strukturen påverka kommunikationen på så sätt att individerna inte alltid kunde föra en dialog. Medarbetarna som satt och arbetade i cellkontor å andra sidan upplevde att dörren ibland kunde vara ett hinder i deras kommunikation och samarbete med de andra. För att kommunicera och samarbeta med andra behövde medarbetaren visa sig tillgänglig genom att hålla sin dörr öppen.

    CORPORATE SOCIAL RESPONSIBILITY AS A CATALYST FOR CONSUMER CHOICE2014Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Even though research on CSR activities has been on the rise, they do not have generally ratified and widely acclaimed explanation with regard to the variation in consumer response to firms operating within the same industry and supporting the same CSR activities. The aim of this research was to investigate the role of corporate social responsibility (CSR) in catalyzing consumer choice. The writers used quantitative research method whereby data was collected by means of online questionnaires in an online survey. The analysis was carried out through frequency, descriptive, reliability, correlation and regression analyses. We realized that although a relationship exists between CSR and consumer behavior through the three channels including legitimacy, information asymmetry and ethical decision making, CSR does not drive sales, but increases the appetite for more CSR information for use in product assessment. Therefore, the engagement in CSR may only increase purchasing and evaluation intention, but not the actual purchase. Given that CSR directly results in the increased information search, the best way to orient CSR to stimulate consumer purchase is through the availability of CSR information to the consumer through localization of CSR activities alongside product excellence and competitive product pricing. Our recommendation is that future research should consider smaller geographical zones, for instance an institution or a city.

    Icke farmakologisk egenvård vid sömnstörningar: en litteraturstudie2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Sömnen är ett av personers viktigaste behov. När en person får för lite sömn ger detta kroppen sömnbrist, vilket påverkar flera funktioner i kroppen negativt som behövs för att vi ska kunna fungera. Sömnbrist kan leda till sömnstörning. Sömnstörningar kan vara en egen sjukdom eller ett symtom på en annan sjukdom. En metod för att motverka sömnstörningar är genom egenvård. Icke farmakologiska åtgärder är en egenvårdsmetod. Vilka icke farmakologiska egenvårdsåtgärder som fungerar för de olika personerna påverkar personernas erfarenheter av åtgärderna.

    Syfte: Att belysa personers erfarenheter av icke farmakologisk egenvård vid sömnstörningar.

    Metod: Litteraturstudie med kvalitativ design som baseras på åtta artiklar. Manifest innehållsanalys användes för att analysera artiklarna.

    Resultat: Erfarenheter av icke farmakologiska egenvårdsåtgärder samt Erfarenheter av tekniska hjälpmedel var det två kategorierna som framkom i resultatet. De egenvårdsåtgärder som framkom kunde antingen vara av fysisk karaktär eller påverka sömnen via sinnena. Åtgärder som kräver tekniska hjälpmedel fanns också. Majoriteten upplevdes påverka sömnen och vilan positivt. Erfarenheterna av CPAP och snarkskenan var till största del att de förbättrade sömnen. Däremot var erfarenheterna av tillexempel aromterapi att det inte förbättrade sömnen.

    Slutsats: Erfarenheterna av egenvårdsåtgärderna med fysisk karaktär, såsom fysisk aktivitet och kostförändringar, var till största del positiva. Däremot var erfarenheterna av de egenvårdsåtgärder som påverkar sinnena, som aromterapi och ljusterapi, mer kritiska. CPAP-masken och snarkskenan hade båda fördelar såväl som nackdelar. Däremot fungerar inte samma sorts egenvård för alla personer. Det behövs göras fler kvalitativa studier inom detta område för att syftet helt ska kunna svaras på.

    Sjuksköterskors erfarenhet av användning av tolk vid språkbarriärer: En kvalitativ litteraturstudie2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Samhället blir allt mer mångkulturellt och en större press sätts på att sjuksköterskor kan möjliggöra en fungerande kommunikation med patienter. Om kommunikationen inte fungerar kan en språkbarriär uppstå mellan sjuksköterskor och patient. Då språkbarriärer kan påverka kvaliteten på omvårdnaden är det viktigt att sjuksköterskor kan hantera språkbarriärerna. Genom att använda en tolk kan språkbarriärer hanteras men det finns även brister i användandet av tolk. Syfte: Syftet med studien var att belysa sjuksköterskors erfarenheter av användning av tolk vid språkbarriär. Metod: En kvalitativ litteraturstudie som baserats på 14 vetenskapliga artiklar med kvalitativ ansats. Artiklarna har analyserats med inspiration av Graneheim och Lundmans (2004) samlade beskrivning av innehållsanalys. Resultat: I studiens resultat framkom sju subkategorier: Sjuksköterskors prioriteringar, Sjuksköterskors kunskap om användandet av tolk, Tillgänglighet av formell tolk, Tillgänglighet av informell tolk, Möjligheter vid användning av tolk, Svårigheter vid Sjuksköterskors användning av formell tolk och Svårigheter vid sjuksköterskors användning av informell tolk. Dessa subkategorier resulterade i två huvudkategorier: Sjuksköterskors erfarenheter av att få tillgång till tolk och Sjuksköterskors erfarenheter av användning av tolk. Slutsats: Att sjuksköterskor hade erfarenhet av att tolk var viktigt för att kunna hantera språkbarriärer, det i sin tur gav bättre möjligheter till en god omvårdnad. I sjuksköterskors användning av tolk fanns både möjligheter och svårigheter. I denna studie identifierades en kunskapsbrist i sjuksköterskors användande av tolk. En utbildning i sjuksköterskors användning av tolk ansågs kunna förbättra omvårdnaden vid språkbarriärer.

    Use of antipsychotics, benzodiazepine derivatives, and dementia medication among older people with intellectual disability and/or autism spectrum disorder and dementia2017In: Research in Developmental Disabilities, ISSN 0891-4222, Vol. 62, p. 50-57Article in journal (Refereed)
    Abstract [en]

    Background Although people with intellectual disability (ID) and people with dementia have high drug prescription rates, there is a lack of studies investigating drug use among those with concurrent diagnoses of ID and dementia. Aim To investigate the use of antipsychotics, benzodiazepine derivatives, and drugs recommended for dementia treatment (anticholinesterases [AChEIs] and memantine) among people with ID and dementia. Methods and procedures Having received support available for people with ID and/or autism spectrum disorder (ASD) was used as a proxy for ID. The ID cohort consisted of 7936 individuals, aged at least 55 years in 2012, and the referent cohort of age- and sex-matched people from the general population (gPop). People with a specialists’ diagnosis of dementia during 2002–2012 were identified (ID, n = 180; gPop, n = 67), and data on prescription of the investigated drugs during the period 2006–2012 were collected. Outcome and results People with ID/ASD and dementia were more likely than people with ID/ASD but without dementia to be prescribed antipsychotics (50% vs 39% over the study period; odds ratio (OR) 1.85, 95% confidence interval 1.13–30.3) and benzodiazepine derivatives (55% vs 36%; OR 2.42, 1.48–3.98). They were also more likely than people with dementia from the general population to be prescribed antipsychotics (50% vs 25%; OR 3.18, 1.59–6.34), but less likely to be prescribed AChEIs (28% vs 45%; OR 0.32, 0.16–0.64).

    The Impact of Renewable Energy Cooperatives on the Social Resilience of Their Communities2014Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Major global problems, manifested by climate change and social inequality, reinforce the need for a societal shift towards sustainable practices. This transition requires new approaches in the future design of society. The current energy system, based on fossil fuels and centralized infrastructure is a key contributor to many of the socio-ecological issues related to the sustainability challenge. The intent of this research is to examine renewable energy cooperatives as an alternative to minimize the negative impacts of the current energy system. Using a Strategic Sustainable Development (SSD) approach with a Resilience Attribute Framework, this research explored the presence of resilience attributes (Trust, Diversity, Learning and Self-organization) and sustainability behavior in renewable energy cooperatives. The research then explored, through interview and surveys, the perceived impacts that these cooperatives had on the resilience and sustainability behavior of the wider community. Findings showed that energy cooperatives displayed high levels of the resilience through the attributes of: - Trust: due to non-profit status, ownership structure, localisation and shared values - Diversity: due to member and service diversity - Learning: through collaboration, diverse member knowledge and participation - Self-organization: due to cooperative development, leadership and outcomes (infrastructure and energy knowledge). This study showed that renewable energy cooperatives have numerous impacts on their community however; there were no significant evidence to suggest energy cooperatives transferred their high levels of social resilience to the community.

    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.

    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.

    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.
