    Wetland biomass - suitable for biogas production?2013Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Wetlands have long been used as natural waste water treatment systems to remove excess nutrients from agriculture or other waste waters. Common reed (Phragmites australis) is the most prominent feature of wetlands in Sweden. This wetland vegetation needs to be harvested and can be used as substrate for biofuel production. In this study, common reed and submerged vegetation from two wetlands outside Halmstad have been harvested in August and October and have been used as substrate for anaerobic digestion in a laboratory experiment. August harvested common reed produced on average 147 ml CH4/g VS, October harvested common reed produced 150 ml CH4/g VS while August harvested free floating vegetation produced 130 ml CH4/g VS. Similar methane production was seen from reed harvested in August and reed harvested in October, but the dry weight of October harvested reed is much higher indicating that harvesting in October can be beneficial not only because of more biogas production but also because a late harvest reduces the amount of biomass to be harvested and transported. Apart from that harvesting in October will not affect the migratory birds which use wetlands as resting place during autumn migration.

    Igår, idag, imorgon- en kvalitativ studie om lärares användning av skönlitteratur i historieämnet.2018Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Studien undersöker skönlitteraturanvändningen i historieundervisningen vilket har genomförts utifrån empiriskt material. Det empiriska materialet är framtaget via kvalitativa intervjuer med lärare som undervisar i årskurserna 4-6. Utifrån intervjuer med fem stycken lärare har studien undersökt deras tankar om skönlitteratur i historieundervisningen samt om användningen kan utveckla ett historiemedvetande. Studien har resulterat både för och nackdelar med användningen av skönlitteratur i historieundervisningen. Resultatet visar även att lärare använder skönlitteratur utifrån olika arbetssätt. Studien resulterar i att skönlitteratur i kombination med faktatexter kan utveckla elevers historiemedvetande men att det kräver en bearbetning av skönlitteraturen.

    Att lyckas i Förenade Arabemiraten: -En undersökande studie om standardisering och anpassning av marknadsföringsstrategier i mat- och dryckesbranschen.2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Globaliseringen av vår värld har medfört att många företag idag verkar på flera marknader över hela världen. Vid inträde på en ny marknad i ett nytt land finns det flera saker företaget måste tänka på, en av sakerna är vilken marknadsföringsstrategi som skall användas. Företag kan antingen välja en standardiserad eller en anpassad marknadsföringsstrategi där standardisering innebär att de använder samma strategi för samtliga marknader. Anpassad marknadsföringsstrategi innebär däremot att företaget tar hänsyn till de lokala omständigheterna och utformar sin strategi efter detta.

     

    Syftet med denna rapport är att klargöra vilka faktorer som spelar roll i valet av marknads-föringsstrategi när ett företag ska ta sig in på en ny marknad.

     

    Genom den teoretiska undersökningen fann vi ett antal faktorer som påverkar valet av mark-nadsföringsstrategi. Dessa faktorer är produkt, kultur, preferenser, socialt/etik, lagar/politik, fysisk miljö, demografi, teknologisk & ekonomisk utveckling.

     

    Resultatet av vår empiriska undersökning, som ägde rum i Dubai med tre företag inom mat- och dryckesbranschen, visade att ovanstående faktorer påverkade de undersökta företagen i deras val av strategi. Kultur, lagar och politik var de faktorer som spelade störst roll. Vi fann dock ytterligare en faktor som spelade en viktig roll, nämligen ”ursprungsland”.

    Modeling Bus Load on CAN2012Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The existence of high load and latency in the CAN bus network would indeed lead to a situation where a given message crosses its deadline; this situation would disturb the continuity of the required service as well as activating fault codes due to delay of message delivery, which might lead to system failure.

    The outcome and goal of this thesis is to research and formulate methods to determine and model busload and latencies, by determining parameters such as alpha and breakdown utilization, which are considered as indications to the start of network breakdown when a given message in a dataset start to introduce latency by crossing its deadline which are totally prohibited in critical real time communications.

    The final goal of this master thesis is to develop a TOOL for calculating, modeling, determining and visualizing worst case busload, throughput, networks’ breakdown points and worst case latency in Scania CAN bus networks which is based on the J1939 protocol.

    SCANLA (The developed CAN busload analyzer tool in this thesis) is running as an executable application and uses a Graphical User Interface as a human-computer interface (i.e., a way for humans to interact with the tool) that useswindows,icons and menus and which can be manipulated by a mouse.

    The use of constructed wetlands in the treatment of dairy processing wastewater2011Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Abstract

    The interest in the use of constructed wetlands for the treatment food processing wastewaters including dairy wastewater is growing. The reason is the intention to create clean technologies that can substitute the currently used “environmentally unfriendly” conventional facilities. This paper suggests options for adopting a constructed wetland system to treat wastewaters from diaries. The potential use of two stage wetland systems is investigated. Examples of multi-stage wetland use are reviewed. The calculations based on the k-c * model (Kadlec and Knight 1996) showed that a reasonable option is to use a subsurface wetland 160 m2 area followed by a free water surface wetland 2000 m2 area. However, these calculations are influenced by the use of older data. The most significant effect is the use of the rate coefficient values for both FWS and HSSF wetlands. A comparison is made to show the effects the new data might have on the calculations. Other measures that can increase the efficiency of the suggested wetland systems like filtration media, deep zones and engineering solutions are suggested. Finally, an overall investigation of the costs involved suggests that the wetland option can be cost effective if all the factors that affect the wetland´s construction and functioning are properly dealt with.

    Negative impact of lake liming programmes on the species richness of dragonflies (Odonata): a study from southern Sweden2017In: Hydrobiologia, ISSN 0018-8158, E-ISSN 1573-5117, Vol. 788, no 1, p. 99-113Article in journal (Refereed)
    Abstract [en]

    Liming programmes aiming to restore fish populations are being implemented in many acidified aquatic systems in northern Europe. We studied Odonata communities in 47 forest lakes in SW Sweden, 13 that are currently being limed, and 8 that have previously been limed. Thirty-one species were recorded, with the highest mean number in untreated lakes, followed by previously treated lakes and currently treated lakes. Species communities differed between untreated and limed lakes, but only few rare species found in the untreated lakes were absent in the treated lakes. Likewise, species known to thrive in acid environments were either rare or showed no preferences. Comparing the number of records of odonate species within a large regional area to the proportion of lakes inhabited in our study, we found that seven of the most commonly observed species occurred less frequently in limed lakes than in the untreated ones, including two of the three most common taxa. Reduced species numbers in limed lakes might be due to conditions on other trophic levels, including fish predation. We argue that Odonata should be considered when developing new biological indices of water quality, although the causes of the observed occurrence patterns need to be studied further. © 2016 Springer International Publishing Switzerland

    Idea generation in the fuzzy front-end of small entrepreneurial projects2015Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The success of the new product development (NPD) process is vital for the survival of projects. Especially for small entrepreneurial projects that try to survive in a very competitive environment, affected by constant market and technical changes. Previous literature emphasize the importance of the generation of new ideas, to improve the product concept during the pre-development stage, but it did not pay a lot of attention to the sources of ideas. For this reason, this study aims to develop the knowledge concerning the sources of ideas of small entrepreneurial projects, during the fuzzy front-end (FFE).

    The literature review of this study presents the previous researches that relate to the sources of ideas, during the idea generation stage of the FFE. The structure of the existing model, integrating the sources of ideas, is based on three categories: environmental scanning, innovative organizational culture and joint research.

    An inductive study and a research, based on the analysis of one small high-tech entrepreneurial project, were conducted to cover the literature gap. This choice of methodology reflects the experimental purpose of this research. The empirical data are only primary data, collected by analyzing the diaries of the two entrepreneurs involved in the project.

    Our findings reveal that contact with lead user, entrepreneur experience, customer involvement, brainstorming sessions, competitor analysis, resource constraints and prototype conception represent the main sources of ideas of small entrepreneurial projects in the FFE.

    The practical purpose of this study is to offer some advices to entrepreneurs of small entrepreneurial projects for accessing to sources of ideas, during the idea generation stage of the FFE, and manage their impact on the development of the product concept. The theoretical implications contribute to the identification of new sources of ideas and a proposition of framework of their impact.

    A taxonomy of planning and scheduling methods to support their more efficient use in construction project management2016In: Journal of Engineering, Design and Technology, ISSN 1726-0531, E-ISSN 1758-8901, Vol. 14, no 3, p. 580-601Article in journal (Refereed)
    Abstract [en]

    Purpose: The implementation and control processes of project planning and scheduling involve a wide range of methods and tools. Despite the development and modification and integration of the project management theory with newer scheduling approaches in particular, practitioners’ views on the efficiency and effectiveness of these methods and tools differ. This situation can be attributed in part to a lack of understanding of the most appropriate basis for implementing these methods and tools. This study, therefore, aims to overcome this deficiency by conceptualizing and adopting a taxonomy of planning and scheduling methods.

    Design/methodology/approach: The study is based on a review and discourse analysis of the literature covering a large number of theoretical and empirical studies. The underlying theories of various planning and scheduling methods were analyzed with respect to the taxonomy criteria adopted in the study.

    Findings: Using the taxonomy, the key characteristics of planning and scheduling methods considered in this study were identified and interpreted. These included concepts and theories; key features; suitability and usability; and benefits and limitations. Overall, the findings suggest that project managers should consider taxonomy as a support tool for selecting and prioritizing the most appropriate method or combination of methods for managing their projects. Recommendations include the need for more advanced or multi-dimensional taxonomies to cope with the diversity of project type and size.

    Originality/value: The results of the study allow project managers to improve their current practices by utilizing taxonomy when considering the implementation of planning and scheduling methods. Moreover, taxonomy can be considered as a tool to promote learning on the part of those less experienced in planning and scheduling. Taxonomy can be considered as an initial platform for further research in this area. © 2016, © Emerald Group Publishing Limited.

    RELATIONEN MELLAN SUBJEKTIVT VÄLBEFINNANDE, COPINGSTRATEGIER OCH OPTIMISM BLAND HÖGSKOLESTUDENTER2010Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med föreliggande studie var att undersöka relationer mellan subjektivt välbefinnande, optimism och copingstrategier. Ett ytterligare syfte var att undersöka eventuella skillnader mellan män och kvinnor angående dels vilka copingstrategier som används, dels skillnader i sambandet mellan copingstrategier, optimism och subjektivt välbefinnande. Studien var baserad på ett stickprov med 106 studenter på grundnivå i olika ämne vid en högskola. Kortversioner av frågeformulären som mäter copingstrategier, optimism och subjektivt välbefinnande delades ut och besvarades enskilt. En multipel korrelationsanalys visade på en modell i vilken coping och optimism förklarade 20% av variansen i subjektivt välbefinnande. Vidare visade resultatet att det inte finns skillnader mellan män och kvinnor när det gäller subjektivt välbefinnande och optimism. Däremot fanns det könsskillnader angående emotionellt stöd, instrumentellt stöd, ventilering av känslor och humor. Copingstrategier medierade inte effekterna av optimism på subjektivt välbefinnande. Subjektivt välbefinnande påverkas till stor del av individens syn på framtiden och livet.

    Bemötandet av patienter med psykisk ohälsa2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Psykisk ohälsa är ett växande folkhälsoproblem idag inom hälso- och sjukvården. Psykisk ohälsa yttrar sig olika för varje enskild individ och gör den därför svår att bemöta. Forskningen visar att det är framförallt kunskapsbristen hos sjuksköterskan skapar en rädsla hos sjuksköterskan och därmed påverkar mötet med patienten. Syftet med systematisk litteraturstudie var att belysa hur sjuksköterskan bemöter patienter med psykisk ohälsa. Resultatet från 12 artiklar med både kvalitativ och kvantitativ ansats har analyserats till två kategorier: Bemötande och Stigmatisering. Sammafattningsvis visar uppsatsen att det krävs empati och förståelse från sjuksköterskan, men likväl utbildning inom området psykisk ohälsa, för att på så sätt minska utrymmet för rädsla och missförstånd. Vidare framkommer det att det krävs vidare forskning som undersöker hur sjuksköterskor som utbildas inom psykiatri förhåller sig i mötet med en patient med psykisk ohälsa. Forskning visar på att en sjuksköterska som har ett gott bemötande även främjar tillfrisknandet men även eliminerar eventuell stigmatisering

    Implementing e-learning in the Jordanian Higher Education Systems: Factors affecting impact2012In: ijEDict - International Journal of Education and Development using Information and Communication Technology, ISSN 1814-0556, E-ISSN 1814-0556, Vol. 8, no 1, p. 121-135Article in journal (Refereed)
    Abstract [en]

    The increased involvement of technology in all aspects of our lives places educational institutions under pressure to include these aspects at the heart of their learning. This ensures that they continue to be competitive in a constantly changing market with international and cultural links. This study explores the factors that influenced the development of learning through technology at two Jordanian universities, focusing on full-time staff and students. It considers the general attitude towards engaging in learning through technology with outcomes demonstrating that training and development is required prior to implementation to adequately support the learning transition. The organisational infrastructure often presents the greatest barrier to such developments. Informed by the outcomes of the study, a training and development programme has been designed, developed and implemented to support the cultural change and increase its impact.

    Exploring Students Acceptance of Technology in Jordanian Universities2013In: ijEDict - International Journal of Education and Development using Information and Communication Technology, ISSN 1814-0556, E-ISSN 1814-0556, Vol. 9, no 2, p. 4-18Article in journal (Refereed)
    Abstract [en]

    Today’s rapid changing world highlights the influence and impact of technology in all aspects of learning life. Higher Education institutions in developed Western countries believe that these developments offer rich opportunities to embed technological innovations within the learning environment. This places developing countries, striving to be equally competitive in international markets, under tremendous pressure to similarly embed appropriate blends of technologies within their learning and curriculum approaches, and consequently enhance and innovate their learning experiences. Although many universities across the world have incorporated internet-based learning systems, the success of their implementation requires an extensive understanding of the end user acceptance process. Learning using technology has become a popular approach within higher education institutions due to the continuous growth of Internet innovations and technologies. Therefore, this paper focuses on the investigation of students, who attempt to successfully adopt e-learning systems at universities in Jordan. The conceptual research framework of e-learning adoption, which is used in the analysis, is based on the technology acceptance model. The study also provides an indicator of students’ acceptance of e-learning as well as identifying the important factors that would contribute to its successful use. The outcomes will enrich the understanding of students’ acceptance of e-learning and will assist in its continuing implementation at Jordanian Universities.

    Parallelization of the Estimation Algorithm of the 3D Structure Tensor2012Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis work provides the implementation of 3D structure tensor on a Massively Parallel Processor Array (MPPA), Ambric 2045.

     

    The 3D structure tensor algorithm is often used in image processing applications to compute the optical flow or to detect local 3D structures and their directions. The 3D structure tensor algorithm (3D-STA) consists of three main parts: gradient, tensor and smoothing. This algorithm is computationally expensive due to many multiplications and additions which are required to calculate the gradient (edge), the tensor and to smooth every pixel of the image. This is why this algorithm is very slow to run on a single processor. Therefore, it is important to make it parallel for high performance computation.

     

    This thesis provides two parallel implementations of 3D-STA; namely coarse-grained parallelism and fine-grained parallelism. Ambric has 336 processors. Only 49 processors are used in coarse-grained implementation and 165 processors are used in fine-grained implementation. The performance of the two implementations is measured using a video stream input, consisting of a sequence of images of size 20x256x256. The performance of the coarse-grained parallelism implementation is 25 frames per second (fps) and the one of the fine-grained parallelism implementation is 100 fps. Thus the fine-grained version is four time faster than the coarse-grained one.

     

    Additionally, the results are compared with the result of the Matlab implementation, running on Intel(R) Core 2 duo @2.10 GHz processor and also compared with another parallel optical flow implementation, in terms of speed and efficiency. The coarse-grained implementation is 58 times faster than the Matlab implementation and it achieves approximately half of the performance of the other parallel optical flow implementation. On the other hand, the fine-grained implementation is 230 times faster than the Matlab implementation and more than twice as (100/43) fast as the other parallel optical flow implementation.

     

    These performance results are satisfactory and the results that our parallel implementations can be considered for real-time applications.

    The three dimensional structure tensor algorithm (3D-STA) is often used in image processing applications to compute the optical flow or to detect local 3D structures and their directions. This algorithm is computationally expensive due to many computations that are required to calculate the gradient, the tensor, and to smooth every pixel of the image frames. Therefore, it is important to parallelize the implementation to achieve high performance. In this paper we present two parallel implementations of 3D-STA; namely moderately parallelized and highly parallelized implementation, on a massively parallel reconfigurable array. Finally, we evaluate the performance of the generated code and results are compared with another optical flow implementation. The throughput achieved by the moderately parallelized implementation is approximately half of the throughput of the Optical flow implementation, whereas the highly parallelized implementation results in a 2x gain in throughput as compared to the optical flow implementation. © 2012 IEEE.

    Abstract [en]

    Through an exploratory experiment using electromagnetic side-channel attack against a keypad for a commercial entry system it is demonstrated that information leakage through side-channels are an ongoing issue and may make entry systems vulnerable by recording of user data.

    Using simple radio equipment, keypresses can be recorded and decoded by undesired electromagnetic radiation and theoretically it is possible to carry out the attack on a longer distance with a specially designed antenna and a custom recieiver.

    The report discusses emission security in consumer products which in military context is termed Tempest or compromising emanations (Swedish: RÖS) and requires expensive tests to be detected and handled.

    The EMC regulations (electromagnetic compatibility) handles radiation and influence of electromagnetic waves in electronic apparatus and nets, but not directly how information can leak from information technology equipment which this report wants to problematize.

    Automatic Pose and Position Estimation by Using Spiral Codes2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This master thesis is about providing the implementation of synthesis, detection of spiral symbols and estimating the pan/tilt angle and position by using camera calibration. The focus is however on the latter, the estimation of parameters of localization.

    Spiral symbols are used to be able to give an object an identity as well as to locate it. Due to the spiral symbol´s characteristic shape, we can use the generalized structure tensor (GST) algorithm which is particularly efficient to detect different members of the spiral family. Once we detect spirals, we know the position and identity parameters of the spirals within an apriori known geometric configuration (on a sheet of paper). In turn, this information can be used to estimate the 3D-position and orientation of the object on which spirals are attached using a camera calibration method.

     

    This thesis provides an insight into how automatic detection of spirals attached on a sheet of paper, and from this, automatic deduction of position and pose parameters of the sheet, can be achieved by using a network camera. GST algorithm has an advantage of running the processes of detection of spirals efficiently w.r.t detection performance and computational resources because it uses a spiral image model well adapted to spiral spatial frequency characteristic. We report results on how detection is affected by zoom parameters of the network camera, as well as by the GST parameters; such as filter size. After all spirals centers are located and identified w.r.t. their twist/bending parameter, a flexible technique for camera calibration, proposed by Zhengyou Zhang implemented in Matlab within the present study, is performed. The performance of the position and pose estimation in 3D is reported.

    The main conclusion is, we have reasonable surface angle estimations for images which were taken by a WLAN network camera in different conditions such as different illumination and different distances.

    Abstract [en]

    The objective of this study is to develop what is called aStudent table, which is designed specifically for school children in emergency circumstances, so it will be suitable for partial solutions for the problems facing children in refugee camps, who are forced to leave their homes and schools. The idea of the study focuses on the creation of the Student table so that the generation of electricity will be suitable for lighting and illumination with the use of some electronic devices used in daily school needs like laptops, so the solar cell system will be connected to a small generator through a hybrid system. A fully functional prototype has been built as part of the study. When the system works through the hybrid route for lighting and illumination the solar system will generate the power needed and when the sun light disappears the Power can be generated by bike pedals. The generation of electricity by the hybrid system is considered as an effective and environmentally friendly option with economic benefits.

    The high-frequency compact radio structure of the peculiar quasar 4C 39.251997In: Astronomy and Astrophysics, ISSN 0004-6361, E-ISSN 1432-0746, Vol. 327, no 2, p. 513-521Article in journal (Refereed)
    Abstract [en]

    We present new high angular resolution images of the compact non-thermal radio source 4C 39.25 obtained from VLBI observations at λ1.3cm, λ7mm, and λ3mm wavelengths. These maps and Gaussian model-fits show that the milli-arcsecond to sub-milliarcsecond structure of 4C 39.25 consists of a complex bent core-jet structure with embedded moving and stationary VLBI components. Facilitated by the small observing beams and high angular resolutions obtained at mm-wavelengths, we measured the relative positions of the jet components with an accuracy of a few hundred micro-arcseconds. This allows the detailed followup of the ongoing merging process of a westward superluminally moving component (b_) with a stationary component a_, located at ~2.9 mas east of the putative core d_. In contrast to the other components of the structure with steeper spectra, the westernmost component d_ exhibits an inverted spectrum peaking between λ7mm and λ3mm, thus further supporting its identification as the VLBI core, self-absorbed at longer wavelengths. From two VLBI maps obtained nearly simultaneously at λ7mm and λ1.3cm, we made the first spectral index map of 4C 39.25 in this wavelength regime. The main characteristics of the spectral index distribution of the jet are pronounced changes of the spectral index between orientations parallel and transverse to the jet axis. Near the merging components a_ and b_ the spectral index steepens with increasing separation from d_. However, in the bridge of emission c_, which connects d_ with a_ and b_, the spectral index gradient has a direction transverse to the jet axis, suggesting a frequency dependent jet curvature and edge-brightening. A brief discussion of this behaviour within current jet models is presented.

    Rullarmering: Att adoptera en armeringsmetod2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Rebar carpet is an innovation that favors the working environment of the rebar workers and saves time. Reinforcement workers today are a vulnerable group. Heavy lifts and backbreaking postures are a part of their everyday work. It is already established that work with rebar carpets is both time-saving, economically beneficial and from a working environment point of view better than traditional reinforcement work. Despite all benefits it is used in rather few projects today.

    The purpose of this study is to identify how the construction industry embraces new innovations related to in situ concrete with post-tensioned reinforcement. The goals are to find out how designers, contractors and manufacturers are working to adopt rebar carpets in the construction process and to shed light on, factors affecting the adoption.

    The study is based on semi-structured interviews with designers, contractors and a representative of a rebar manufacturing company.

    Designers and contractors have not, generally speaking, been actively working to adopt rebar carpet. The governing factors for the use of rebar carpets is the designers and contractors knowledge and previous experience of rebar carpet. The contractors who have previous experience of rebar carpet can imagine using rebar carpet again and contractors with no previous experience believe that they need more knowledge of rebar carpet before they dare to try. Design engineers who have designed for rebar carpet before has it in mind when they design other projects. Designers who have no previous experience of rebar carpet demand more knowledge about how they can facilitate the use of rebar carpet.

    Faktorer i undervisningen av patienter med diabetes mellitus typ 2 som påverkar motivationen att ändra levnadsvanor2007Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    En av vårdgivarens viktigaste uppgift i undervisningen är att motivera patienter med kronisk sjukdom till förändring av levnadsvanor. Syftet med c-uppsatsen var att belysa faktorer i undervisningen av patienter med diabetes mellitus typ 2 som påverkar motivationen att ändra levnadsvanor. Metod: C-uppsatsen genomfördes som en litteraturstudie. Vid granskning av de vetenskapliga artiklarna användes SAUK-modellen som teoretisk referensram. Resultat: Undervisning kort tid efter diagnos och individualiserad undervisning med tillåtande dialog hjälper patienten att bli motiverad. Vårdgivaren ska fokusera på patientens personliga förståelse om sin sjukdom och ha insikt om att patienter har olika utgångslägen gällande i vilket stadium de befinner sig i angående motivation till förändring av levnadsvanor. Kompanjonskap mellan vårdgivare och patient är av betydelse för att patienten ska klara av att integrera sjukdomen i det dagliga livet och uppnå självkompetens. Slutsatsen är att det finns faktorer i undervisningen av patienter med diabetes mellitus typ 2 som påverkar motivationen att ändra levnadsvanor. Bekräftande omvårdnad i undervisningen får patienten att känna sig sedd, hörd och tagen på allvar vilket ökar motivationen att ändra levnadsvanor. Förändring av levnadsvanor är nödvändigt och undervisningen av patienter ska medverka till att sena komplikationer undviks. Vidare forskning vore önskvärt om huruvida SAUK-modellens bekräftande omvårdnad kan implementeras i den svenska hälso- och sjukvården.

    EN STUDIE AV TILLVÄXTUTVECKLING I SMÅFÖRETAG: EN STUDIE PÅ LEDARE OCH PERSONAL I SVENSKA SMÅFÖRETAG MED SNABB TILLVÄXTUTVECKLING2008Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med studien var att undersöka och beskriva varför en del snabbväxande företag har haft en fortsatt positiv tillväxtutveckling medan andra har fått en negativ tillväxtutveckling, då man har haft samma yttre förutsättningar. Undersökningen har utförts genom att författarna hade som mål att visa tillväxtutvecklingen i företag sex år efter att de hade genomgått en snabb tillväxt. Därefter gjorde författarna en kvantitativ undersökning där nio stycken företag intervjuades per telefon. Resultatet visade att flera av de hypoteser vi hade satt upp stämde väl överens med de svar vi fick i intervjuerna. Vi kunde då se att företag som arbetar tvärfunktionellt får ett bättre samarbete i företaget. Det visade sig även i studien att företag som har haft en negativ tillväxt ska försöka att få in en bättre öppenhet i företagen så att man bättre kan förmedla de mål som företaget har och på det viset nå en ökad tillväxt. Vi kom också fram till slutsatsen att de företag som har haft en negativ tillväxt, ska för att lyckas öka sin tillväxt uppmuntra sin personal till vidareutbildning då vi har visat att det ger företagen en ökad konkurrenskraft. Man kunde även se att de VD som arbetar i de företagen som har haft en negativ tillväxtutveckling, bör lägga ner mer tid än tidigare på att utveckla företaget och lägga ut arbetsuppgifter som han/hon själv tidigare har utfört till andra personer, då detta har visat sig leda till att företagen får en mer positiv tillväxtutveckling.

    MindMe: Ett minnesstöd för en trygg och självständig vardag2009Independent thesis Basic level (university diploma), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    The bachelor thesis, MindMe has been realized in cooperation with Niclas Jarhäll at Mutual Benefits AB, Gothenburg. Mutual Benefits AB is a consulting firm, which delivers technical consulting services and products. The bachelor thesis was meant to result in a memory aid for people with a cognitive handicap, which has an impaired memory loss. The project focused on people diagnosed from ADHD (Attention deficit/Hyperactive Disorder) and acquired brain disorder. Early in the project, studies were performed that found an expressed need of a memory aid within this group. The studies also showed that our target group often mislays their personal belongings, as keys, wallet and mobile phone. This causes big anxiety in their daily life. Something that people with a cognitive handicap value highly, is to live their daily life with a sense of safety and independence. However, it is far too many of toady’s memory aids that either ridicule the user, or offers a too complicated solution. Early in the project, a test group was founded with people with a cognitive handicap. Throughout the test group, we found requirements from the users’ point of view, that is something that we think is important for a successful project! MindMe is a memory aid that the user can control from their own mobile phone. With an suited software and three tags, MindMe can offer a simple and personalized aid. The solution has passed through both functional tests and user tests and has been evaluated by a big network. The project has a potential distributor, for a distribution through the county councils of Sweden. The distributor is also interested in adding capital for MindMes further development. During 2008/2009, the project group participated in the business plan competition, Venture Cup. In November 2008, Mindme won a price for one of the best regional business ideas. It feels stimulating to have succeeded to develop a product that both users and outer parts appreciate. MindMe is planned to be introduced for the market in 2010, according our business plan. Our expectations are that more people realize the advantages by using a mobile phone as an aid. Furthermore, we hope that MindMe can offer our target group an every day solution for a safe and independent feeling...

    Mellanmänskliga relationers inverkan på den psykiska hälsan: En kvalitativ studie i ett återhämtningsprojekt2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med föreliggande uppsats är att utifrån ett socialpsykologiskt perspektiv undersöka och öka förståelsen för hur mellanmänskliga relationer inverkat och inverkar på den psykiska hälsan hos personer som under denna studies inledning var sjukskrivna för någon form av psykisk ohälsa. Samtliga informanter ingår i ett aktuellt treårigt projekt, vars syfte är att öka individens välbefinnande och som när denna studie inleddes pågått under cirka ett halvår.

     

    Studien har en kvalitativ ansats och baseras på sex semistrukturerade intervjuer som har karaktären av narrativa livsberättelser.

     

    Resultatet visar att tillit och acceptans i relationen till medmänniskor i det dagliga livet är en mycket viktig faktor för informanterna gällande att deras återhämtning ska uppnå goda resultat. Resultatet visar också att det inte har varit de tidigare relationerna i sig som orsakat informanternas psykiska ohälsa utan snarare de destruktiva emotioner som tidigare relationer genererat.

    "Det handlar om okunskap om hur det är att vara funktionshindrad": En kvalitativ studie om samhällets bemötande gentemot personer med synliga fysiska funktionsnedsättningar.2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna studie är att öka förståelsen för hur personer med synliga fysiska funktionsnedsättningar upplever den psykosociala tillgängligheten i samhället och hur en eventuell brist av denna tillgänglighet påverkar dem känslomässigt. Studien använder sig av en kvalitativ metod med semistrukturerade intervjuer som datainsamlingsmetod. Studien är också inspirerad av en hermeneutisk ansatsmetod då syftet är att tolka informanternas upplevelse av till exempel bemötande från människor i samhället. Fem informanter i åldrarna 47-74 år deltog i studien och alla personerna hade själv olika former av synliga rörelsehinder, tre informanter är kvinnor och två är män. Studiens resultat visade på att dess informanter upplevde den psykosociala tillgängligheten, gällande exempelvis bemötandet och attityder, olika. Det syntes vissa tendenser till att skillnaden kunde bero på kön, där männen upplevde det generella bemötandet bättre än kvinnorna, men det kunde också bero på egna attityden, och/eller självacceptans. Att bemötandet inte alltid var tillfredsställande verkar bero på en kunskapsbrist vilket är något som informanterna upplever att samhället behöver arbeta mer med, framförallt inom skolan och hos politikerna. Resultatet analyserades, med hjälp av en tematisk analys, i förhållande till de vetenskapliga teorierna, stigmateorin och cripteorin, samt i förhållande till tidigare forskning inom ämnet.

    Motiven bakom en investering i crowdfunding2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    It is well known that small businesses and entrepreneurs in the initial phase has difficult to gain access to external capital and bank loans. With the background of the problems that entrepreneurs face when they ask for capital has since the financial crisis the phenomenon of crowdfunding developed and evolved. Crowdfunding is an alternative source of funding for entrepreneurs to fund their ideas through small or medium-sized capital contribution from a larger amount of investors, often investors who have any kind of relationship with the entrepreneur or to the very idea. This study examined the factors that motivate and guide an investor's decisions when they select their projects. The results of the study show that the motives of the various existing forms of crowdfunding is big. To answer the question of what can affect an investor's motives, the form of crowdfunding must be mentioned. The motivational factors in the study turns out to be local projects, social benefits in the form of altruism, affiliation, shared values as well as the monetary returns and material rewards.

    Sjuksköterskans attityder gentemot homosexualitet: - ur ett patientperspektiv2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Att avslöja sin homosexuella läggning blir allt vanligare i dagens samhälle, dock lever negativa attityder gentemot homosexualitet och homosexuella individer kvar. I vården som i resten av samhället speglas vi av heteronormativa attityder och tankar. Det förutsätts att de flesta människor lever enligt den heterosexuella normen, vilket kan göra det svårare för homosexuella personer att komma ut och vara öppna om sin homosexuella läggning. Syftet med denna litteraturstudie var att belysa patienters upplevelse av sjuksköterskans attityder och bemötande gentemot deras homosexuella läggning. Litteraturstudien utformades utifrån en induktiv ansats, där 14 vetenskapliga artiklar användes till resultatet. I resultatet framkom det att hälso- och sjukvården upplevs styras av ett heteronormativt tankesätt, där patienten antas vara heterosexuell. Bristfällig kunskap hos sjuksköterskor och annan vårdpersonal var något som upplevdes av flera informanter. Många var också rädda för att avslöja sin homosexuella läggning på grund av oro för sämre vård och negativa attityder ifrån vårdpersonal. Framtida forskning bör inriktas på vidare studier av patienter som är homosexuella och deras upplevelser av hälso- och sjukvård och dess attityder gentemot homosexualitet. Det kunde också vara intressant att studera om det fanns skillnader mellan homosexuella män och kvinnor när det gäller deras upplevelser av bemötandet inom vården.

    Kommersialisering av universitetsforskning: En studie av kommersialiseringsprocesser och deras stödfaktorer2004Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [sv]
    Sweden spends more money as a percentage of the GDP on research and development (R&D) than any other OECD country. The outcome is however relatively modest with few new enterprises based upon high technology innovations, the so-called Swedish paradox. One way to increase the number of new high technology companies is by increasing commercialization of university research, so called Research Based Spin-Offs (RBSOs). The universities have a key role in transforming the scientists’, often, minor knowledge in entrepreneurial issues. Moreover, it is important to start more new RBSOs based upon these results. With this in mind we found it most interesting and challenging trying to find key issues that play a vital role in commercialisation of research results. The purpose of the thesis is to describe the commercialization process from five swedish institutions and identify the key actors in the process. We will, in addition to this, create knowledge of factors influencing the level of research-based commercialization.

    Skolsituation och lärande2007Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Vi lever idag i ett mångkulturellt samhälle och detta märks inte minst i dagens skola där

    ungdomar med olika kuiturella bakgrunder möts utifrån olika förutsättningar. Alla elever i

    dagens svenska skola lever i en vardag fylld med massor av påverkan ifrån olika kulturer och

    ifrån olika människor. Skolan är också en del utav det mångkuiturella samhället där elever

    dagligen med olika kulturella bakgrunder möts och samspelar med varandra. Alla elever i

    skolan matas hela tiden med intryck av olika slag och påverkan från olika håll i omgivningen,

    till exempel från lärare, kamrater och föräldrar. Med denna studie vill vi belysa hur elever

    med invandrarbakgrund i den svenska skolan ser på sin skolsituation och sitt lärande. Som

    blivande lärare är det viktigt att kunna tillgodose alla elever utifrån den enskilda individen och

    det är av stor väsentlighet att bidra med ett lärande. Ett lärande som är givande för alla elever

    då även elever med invandrarbakgrund är en stor del av den svenska skolan. Att kunna

    tillgodose alla elever på bästa möjliga sätt är för oss den stora utmaningen i läraryrket. Viktigt

    är att kunna vara flexibel och uppmärksam, detta är för läraren en del utav läraryrkets

    profession. Bakgrunden och valet av inriktning, där vi sätter eleven med invandrarbakgrund i

    fokus är på grund av att vi som blivande lärare har stött på och uppmärksammat problem ute i

    den svenska skolan genom exempelvis våra VFU perioder men även erfarenheter från vår

    egen skolgång. Vi kälmer att problemen som vi stött på ute i skolorna måste lyftas fram för att

    kunna få en verklig bild av hur det egentligen ser ut, det vill säga om den svenska skolan har

    problem med att kunna tillgodose alla elever utifrån bästa möjliga förmåga oavsett kuiturell

    bakgrund. I denna studie vill vi söka svar om hur elever med invandrarbakgrund i den svenska

    skolan ser på den egna skolsituationen. Vi utgår från elevemas egna upplevelser och tankar

    för att finna svar om det är en verklig bild som vi har stött på, vill säga om vårt antagande går

    att generalisera över lag i den svenska skolan. De didaktiska implikationer vi har utgått ifrån i

    vår studie är att vi anser det vara av stor pedagogisk relevans att uppmärksamma de problem

    som vi stött på för att underlätta för alla elever i den mångkuiturella skolan. Vi anser att skolan är en plats där alla elever ska känna sig trygga och kunna utvecklas efter egna förutsättningar, den ska inte hämma och hindra den personliga utvecklingen hos eleverna vilken den idag utifrån vår synvinkel till viss del tyvärr gör. Vårt intresse ligger då här att

    undersöka om det är den kulturella bakgrunden som på något sätt kan ligga till bakgrund för

    de eventuella svårigheterna. I studien har vi valt att utgå utifrån två olika nivåer där den första

    nivån belyser teorier om elevernas allmänna skolsituation där vi anser att begrepp som kultur,

    och identitet är kopplade till hur eleven ser sig själv vara en del av skolan. Den andra nivån

    behandlar elevens lärande och hur/om dessa ovannämnda begrepp kan vara påverkbara i

    själva lärandet.

    Combined use of Iteration, Quadratic Interpolation and an Extra Kernel for high-resolution 2D particle tracking: a first evaluation2010In: 2010 ieee international ultrasonics symposium, New York: IEEE Press, 2010, p. 2000-2003Conference paper (Refereed)
    Abstract [en]

    A novel 2D particle tracking method, that uses 1) iteration, 2) fast quadratic sub-pixel estimation (with only 28 multiplications per movement), and 3) a previous kernel, has been evaluated and compared with a full-search block-matching method. The comparison with high-frequency ultrasound data (40 MHz) was conducted in silico and on phantoms, which comprised lateral, diagonal, and ellipsoidal movement patterns with speeds of 0–15 mm/s. The mean tracking error was reduced by 68% in silico and 71% for the phantom measurements. When only sub-pixel estimation was used, the decrease in the tracking error was 61% in silico and 57% for the phantom measurements. As well as decreasing the tracking error, the new method only used 70% of the computational time needed by the full-search block-matching method. With a fast method having good tracking ability for high-frequency ultrasound data, we now have a tool to better investigate tissue movements and its dynamic functionality.

    Improved tracking performance of lagrangian block-matching methodologies using block expansion in the time domain: In silico, phantom and invivo evaluations2014In: Ultrasound in Medicine and Biology, ISSN 0301-5629, E-ISSN 1879-291X, Vol. 40, no 10, p. 2508-2520Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to evaluate tracking performance when an extra reference block is added to a basic block-matching method, where the two reference blocks originate from two consecutive ultrasound frames. The use of an extra reference block was evaluated for two putative benefits: (i) an increase in tracking performance while maintaining the size of the reference blocks, evaluated using in silico and phantom cine loops; (ii) a reduction in the size of the reference blocks while maintaining the tracking performance, evaluated using in vivo cine loops of the common carotid artery where the longitudinal movement of the wall was estimated. The results indicated that tracking accuracy improved (mean - 48%, p<0.005 [in silico]; mean - 43%, p<0.01 [phantom]), and there was a reduction in size of the reference blocks while maintaining tracking performance (mean - 19%, p<0.01 [in vivo]). This novel method will facilitate further exploration of the longitudinal movement of the arterial wall. (C) 2014 World Federation for Ultrasound in Medicine & Biology.

    Energianvändning på Volvo Lastvagnar Tuve2007Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Volvo Trucks is the second largest manufacturer of heavy trucks, with factories in several countries and with around 21 000 employees. At the plant in Tuve, trucks have been built since 1982 and the activity mainly consists of producing side members and to assemble and packing kits of trucks.

    In 2005, the factory in Tuve launched the ambition to be the first carbon dioxide neutral vehicle factory in the world. This will be implemented by streamlining and investing in renewable energy.

    The aim of this degree thesis is to map the usage of energy within production, and also to prepare a method to measure key figures (use of energy per produced unit). The purpose with the thesis is to make it possible to measure and analyze performed energy saving measurements, and to identify areas within production where there is potential to save energy. The report also considers proposals for energy saving measurements in both production and in the factory in general.

    It appears that the assembly of trucks represented a tiny part of the total usage of energy in the factory, while the process of side member production and application of rust protection used the most energy.

    The thesis gives proposals for four methods to key figures measurements. These are connected only to the assembly part of the factory, and the difference between the methods depends on the way of measure the heat consumption.

    Key words

    Use of energy, mapping/survey, key figures, streamlining use of energy

    Cykelgymnasiet i Skara: En kvalitaiv studie om elevernas uppfattningar om skolan och framtiden2002Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]
    The purpose of this study was to investigate how students of the cyclesport academy conceptualize their situation on the academy and their future. Nine cyclesport students in second and third grade, six males and three female were interviewed. The coach of the academy was also interviewed. The method used was qualitative and interviews were made. Themes that emerged in the interview guide was Preferences & Options, Future, Social Support, Goalsetting, Motivation and Gender aspect. The result showed that the students are unanimous that the cyclesport academy promotes their development. Some of the students regarded that they don´t get enough of attention from the academy teachers/coach. Most of the students see their future as positive and they believe that they will continue to cycle after academy. Some of the students believe that there could be problems to motivate themselves after academy, because the situation at the academy is to good. Many of the students think that they will continue to study at higher level, in most cases, after the cycle carrier. The students believe that their studying has suffered a bit because of the cycling, but it doesn´t seem to have caused them any problems.

    Lagidrottares upplevelse av målsättningens effekter: En kvalitativ studie av lagidrottare på elitnivå2001Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]
    Syftet var att studera hur svenska lagidrottare på elitnivå upplever effekterna av målsättning. Tio stycken lagidrottare, åtta män och två kvinnor, intervjuades om deras subjektiva upplevelse av målsättningseffekterna. Intervjuformen var semistrukturerad med en intervjumall som utvecklats och modifierats utifrån enkäten “Goal Setting in Sport Questionnaire”. Teman som framkom genom GSSQ var hur ofta målsättning används, hur effektivt målsättning är, vilja/ansträngning att uppnå mål och målsätningspreferenser/valmöjligheter.Tillägg har gjorts med teman målsättning, självförtroende, motivation och lagsammanhållning. Resultatet av undersökningen visade att försökspersonerna använder sig av resultat och prestationsmål men inte processmål som anses vara effektivast. Resultaten överensstämmer med Goal Achivement Theory, att uppnådda mål och uppfattad förmåga avgör vilken grad av ansträngning och uthållighet som idrottaren väljer. En effekt av målsättningen är att försökspersonerna anser att de behärskar aktiviteten bättre med målsättning som kan kopplas till Self-Efficacy Theory. Vidare visar resultatet att målsättning främjar gruppsammanhållningen. Ett anmärkningsvärt resultat var att få försökspersoner utvärderar sin målsättning.

    Vad motiverar cyklingen hjälpryttare på svensk elitnivå?2001Student paper second termStudent thesis
    Abstract [sv]
    Syftet med undersökningen var att ta reda på vad som motiverar hjälpryttare att cykla. Detta har undersökts med hjälp av semistrukturerade intervjuer där urvalsgrupen bestod av fyra manliga cyklister och en manlig tränare. Intervjumallen som användes utformades från enkäterna Motiv Till Idrottsdeltagare (MTI) och Perceived Motivational Climate in Sport Questionnaire (PMCSQ). Resultaten visade att hjälpryttaren är motiverad att vinna men det viktiga är inte att han själv vinner utan att det är dennes lag som vinner. Alla respondenter påpekade att de då och då får chans att vinna själva och det gör det kanske lättare att motivera sig att agera hjälpryttare under större delen av säsongen. Hjälpryttarna känner sig totalt sett motiverade till de olika uppgifter de blir tilldelade och att det är själva uppgiften i sig som motiverar hjälpryttaren. Hjälpryttarna har multipla motiv för att delta och de är både inre och yttre. Vidare känner de sig framgåpngsrika då de förbättra sig och de känner att de får uppmärksamhet från omgivningen. En slutsats man kan dra är att hjälpryttarna är lika motiverade som de andra i laget.

    Har du mens eller?: Kvinnors erfarenheter av att leva med PMS2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Premenstrual syndrome, also known as PMS, is a phenomenon that is estimated to effect 20-30% of all menstruating women. The premenstrual symptoms appear in the lutheal phase of the menstrual cycle and usually recurs monthly. The aim of this study was to describe the experiences of women with premenstrual syndrome. This study is conducted as a literature study, based on ten scinentific articles. Three major themes were identified from the results of the articles. The results of the literature study illustrates that women often experience disbelief when they try to describe their premenstrual experiences. The disbelief often occurs in relation to describing PMS to partners, co-workers and health care professionals. The study also shows that there is a great ignorance about PMS and the phenomenon is often portrayed negatively and ridiculed. Many women described the value of getting to talk about their premenstrual experiences without being judged and met with disbelief. It is of great importance that through education develops the nursing care and increase awareness among health care professionals about female phenomena such as PMS. To help women relieve the suffering the premenstrual symptoms can cause, it is important that further research is conducted.

    Omvårdnadsåtgärder i relation till urinvägsinfektion2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Urinvägsinfektion kan anses okomplicerat men tillståndet kan leda till onödigt lidande och påverka patienters välmående, dagliga aktiviteter och sociala liv. Sjuksköterskan saknar tillräckligt med evidens för att utföra lämplig omvårdnad relaterat till urinvägsinfektion. Caring och Nursing är perspektiv för forskning inom sjuksköterskans vetenskap. Syfte: Beskriva vad omvårdnadsåtgärder är i relation till urinvägsinfektion. Metod: En litteraturstudie genomfördes utifrån en systematisk sökning i databaser för omvårdnadsforskning. Nio vetenskapliga artiklar analyserades med frågor som stöd och inspiration från ett hermeneutiskt förhållningssätt. Resultat: De vetenskapliga artiklarna resulterade i fem kategorier: Behov och bemötande, Observation och övervakning, Upprätthålla hygien och vätskeintag, Utbildning och attityd och Kunskap och utvärdering. Resultatet belyser att kontinuerlig undervisning och teamarbete kan uppmuntra till ökad medvetenhet kring omvårdnadsåtgärder och öka patientsäkerheten. Det är viktigt att patienter känner att de blir hörda samt att problem uppmärksammas och tas på allvar.  Slutsats: Forskning kring omvårdnadsåtgärder i relation till urinvägsinfektion är bristfällig. Litteraturstudien lyfter fram och ökar medvetenheten om vilka omvårdnadsåtgärder som kan impliceras i omvårdnadsarbetet.

    Kunskap och Engagemang - Reducering av missbruk mellan generationer2008Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Abstract

    Titel: Kunskap och Engagemang - Reducering av missbruk mellan generationer

    Uppsats: Sociologi C, 61-90p

    Handledare: Magnus Ring

    Syftet med denna uppsats är att studera vilka faktorer som möjligtvis skulle kunna minska reproduktionen av missbruk mellan generationer. Vi har utgått från två verksamheter, det vill säga, Vändpunkten och BIM (Barn i missbruk). Vi har utfört en enkätsammanställning åt BIM, för att ta reda på vad verksamheten har gett de ungdomar som deltagit i BIMs gruppträffar. Metoderna vi har använt oss av för att behandla vårt insamlade material är både kvantitativ- och kvalitativ metod. Vi har utgått ifrån sociologiska teorier som vi anser är relevanta för vårt valda ämne. Vi har använt oss av Berger och Luckmanns primär- sekundär socialisation och institutionalisering samt Beckers avvikarbegrepp. Dessutom har vi valt att utgå från Hansens beskrivning om barn som lever i missbruk och Bergströms framställning om missbruk, människor och relationer. Vår frågeställning lyder: hur minskar man reproduktionen av missbruk mellan generationer? För att kunna minska reproduktionen av missbruk är vår slutsats att det krävs främst; kunskap kring missbruk och engagemang från medmänniskor och verksamheter. Förståelse kring missbruk ökar sannolikheten att individer i samhället reagerar samt agerar och det kan därmed bidra till att de människor som lever med eller i missbruk kan bli hjälpta, vilket kan leda dem på rätt väg. Vi har kommit fram till att skolan är ett viktigt forum för att sprida kunskap. Vi har ytterligare kommit fram till att medmänniskors och verksamheters engagemang har en viktig betydelse för människor i missbrukarmiljöer och för deras framtidsutsikter. Människor och verksamheter som engagerar sig konfronterar individer med missbruk, stöttar och ställer krav, vilket kan vara den nödvändiga kraften för att hjälpa individen ur sitt missbruk. Engagerade verksamheter, så som BIM och Vändpunkten, fungerar bland annat ”jag-stärkande” för individer som är i behov av det, detta i sin tur kan förhindra utvecklingen av missbruk i framtiden, för dessa individer.

    INKLUDERANDE ARBETSSÄTT I FÖRSKOLAN: en studie om hur pedagogers förhållningssätt påverkar barns delaktighet2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna studies syfte är att beskriva inkludering och delaktighet i förskolan, hur pedagoger arbetar för att få barnen inkluderade och uppleva delaktighet. Frågeställningarna i studien är, på vilket sätt visar sig ett barncentrerat förhållningssätt i relation till barns delaktighet? På vilket sätt visar sig ett vuxencentrerat förhållningssätt i relation till barns delaktighet? Data inhämtades genom observationer på en förskola i halland. Resultatet visar att när pedagogen har ett barncentrerat förhållningssätt bidrar det till ömsesidig delaktighet, barn emellan och mellan barn och vuxen. Om två pedagoger ingår i en aktivitet och den ena pedagogen intar ett vuxencentrerat förhållningssätt och den andra ett barncentrerat, tenderar det vuxencentrerade förhållningssättet att ta överhand. Det är en svår uppgift för pedagogen att få alla barn inkluderade om arbetslaget har olika förhållningssätt.

    The impact of mergers & acquisitions on corporate identities and brand portfolios in the automotive industry: A case study of Renault & Dacia2011Independent thesis Advanced level (degree of Master (One Year)), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    The today‟s business world deals with an increasing phenomenon of Mergers and Acquisitions (M&A‟s), a process through which companies gain access to some tangible and intangible resources. Within the automotive industry this phenomenon requires even more attention, since it faced many difficulties during time. This can be seen through the numerous mergers/acquisitions failures, among which it can be mentioned the one of Daimler & Chrysler, Volvo & Renault, BMW & Rover, which were also treated in the thesis. However, although fewer, there are also M&A‟s that became successful, such as the acquisition of Skoda or Seat by Volkswagen, or the acquisition of Dacia by Renault. The last example captured the attention of the study in particular.However, although they are mostly defined by similar characteristics, the mergers and acquisitions mean slightly different things. An acquisition occurs when an organization takes over another one and establishes itself clearly as the new owner, while a merger occurs when two companies, of a similar size, create a single new company owned and operated by both of the parties.The very purpose of the thesis was to reveal the possible impact of mergers and acquisitions regarding the brand perspective in the automotive industry, through the eyes of the case studies mentioned above and the case of Dacia & Renault in particularThe study chose to use an inductive approach, meaning that the researcher had first collected data from Dacia and afterwards, according to the information owned, he developed the theoretical framework. The study is furthermore exploratory, since the researcher sought to explore Dacia‟s approach to branding under Renault ownership.The interesting part consists in the paper‟s findings. First it was discovered that the companies that merge, sometimes face difficulties in establishing the corporate identity of their new formed company. In the case of acquisitions however the process of adopting a new corporate identity applies mostly to the acquired company and overall it is a bit more clear what strategy should the acquired company adopt. On the other hand the paper also identified the M&A‟s impact on the new portfolio. When both are eager to keep their own corporate and product brands, the new portfolio becomes too complex and does not allow cost savings synergies in terms of components equalization, production rationalization or marketing. However, due to the investments that the acquiring company usually makes, the new portfolio can also become more competitive.Regarding the case study on which the paper chose to focus, it was revealed the Dacia‟s corporate brand strategy that boosted its sales and revived its identity. Afterwards it emerged Dacia‟s portfolio consisting of brands that complement themselves and therefore address a wide spectrum of customer needs, and the brands‟ dynamics in time.
