    Personalomsättningen inom revisionsbyråer – Ett problem?: En studie om personalomsättning på stora och små revisionsbyråer2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    A certain level of employee turnover is necessary for the organization’s continuous profitability. However, employee turnover in the audit profession is described as a problem. Previous studies have explored different aspects of turnover at the individual level. Where factors have been identified for why associates chooses to leave audit firms. Previous studies have also focused on the influence of different methods on the individual's decision to leave the industry. The purpose of this study is to analyze employee turnover from the audit firms´ perspective, and then identify differences between large and small audit firms. To answer the research questions and fulfill the purpose, both a questionnaire and interviews have been performed. The questionnaire was sent out to audit offices around Sweden and provided answers from 32 different offices. Four auditing firms in Norrbotten were then interviewed, two small and two large auditing firms. The study shows that audit firms in Norrland have a low employee turnover, but turnover in the industry as a whole is still considered too high. The main conclusion of the study is that turnover varies between audit firms and that the size of the firm is an explanatory factor. In addition, the study shows that management and external factors have an impact on turnover. However, external factors cannot be influenced by management, but is something that management should adapt to in order to retain its employees.

    Mitigating Not-Invented-Here & Not-Sold-Here Problems: Leveraging External Ideas through Corporate Innovation Hubs2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Purpose – The purpose of this study is to understand How Corporate Innovation Hubs (CIHs) can Mitigate NIH and NSH Problems in Knowledge Transfer. To fulfill this purpose, the following research questions were derived: RQ1: What are the causes of NIH & NSH problems among actors collaborating through a CIH? RQ2: What are the consequences of NIH & NSH problems among actors collaborating through a CIH? RQ3: What mechanisms can a CIH use to mitigate NIH & NSH problems among collaborating actors?

    Method – The study is an explorative inductive multiple case-study, investigating five CIHs situated in either Silicon Valley, US or Gothenburg, Sweden. In total, 39 interviews were conducted in three waves, and results were derived using a Gioia analysis.

    Findings – This study resulted in a framework illustrating connections of causes and consequences of NIH and NSH problems with corresponding mitigating mechanisms. The most critical causes are Obsessive control (NIH), Internal antagonism (NIH) and Low confidential awareness (NSH). The most severe consequences are Use of irrelevant knowledge (NIH), Suffocation of external ideas (NIH) and Restrained problem-solving (NSH). The most important mitigating mechanisms are Translate relevance of ideas (NIH) and Create mutual confidential understanding (NSH).

    Theoretical and Practical Implications – This study contributes to the scarce literature on NIH and NSH problems among multiple actors collaborating through CIHs. By identifying causes, consequences and mitigating mechanisms of NIH and NSH problems, CIHs will be able to detect NIH and NSH tendencies among its collaborating actors, to mitigate its causes and prevent its consequences.

    Limitations and Future Research – The study is limited by the investigated CIHs focus on exploring future transportation solutions, indicating that future studies can investigate CIHs in other industry settings and among other actors collaborating through CIHs.

    Keywords: Corporate Innovation Hubs; NIH; NSH; Knowledge Transfer

    Tredjepartsleanlogistik - Minimera slöserier hos ett tredjepartslogistikföretag: En fallstudie vid Reach Logistics AB2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Det ställs allt högre krav på att logistikprocesserna ska vara effektiva vilket har resulterat i en ökad tredjepartslogistikmarknad då företag måste fokusera på sin kärnverksamhet. Den växande marknaden har lett till stor konkurrens bland tredjeparslogistikverksamheter, vilket har resulterat i små vinstmarginaler inom branschen. För att verksamheterna ska vara fortsatt konkurrenskraftiga behöver de därför bli så Lean som möjligt. Syftet med den här studien är därför är att kartlägga verksamhetens nuvarande lagerhantering och paketering för att identifiera problem och slöserier. Vidare syftar även studien till att öka effektiviteten hos ett tredjepartslogistikföretag genom att reducera de slöserier och problem som identifierats vid kartläggningen.

    Studien har genomförts hos fallföretaget Reach Logistics AB i Borås. Reach Logistics AB är ett logistikföretag som bland annat tillhandhåller tredjepartslogistik. Deras tredjepartslogistik erbjuder delar som infrakt, transport, leverans, samt lager- och returhantering. Projektet innehållerfyra faser; planering, datainsamling, analys och utformning av slutsats. Datainsamlingen bestod av bland annat studiebesök med observationer samt flertalet intervjuer med de anställda på fallföretaget. Cykeltiden för varje station uppmättes också för att se om några flaskhalsar förekom. Sedan analyserades informationen med hjälp av värdeflödesanalys.

    Studien resulterade i att flertalet slöserier och problem identifierades hos fallföretaget. Rörelse var det slöseri som var mest frekvent förekommande. Ett annat problem som identifierades var det ojämna flödet med flertalet flaskhalsar som resulterade i att aktiviteter som var icke-värdeskapande för kunden utfördes. Det framkom även att personalen ofta utförde arbetet på olika sätt utefter vad de själva ansåg vara bäst.

    Förbättringsförslag togs fram till respektive slöseri och problem. För att utjämna flödet föreslogs bland annat att dubbla kapaciteten i vissa stationer, implementera metoden 5S samt att införa standardiserat arbetssätt. Ett annat förbättringsförslag var att placera ut den mer erfarna personalen på rätt station för att minska rörelse och på så sätt erhålla ett effektivare flöde. De enskilda förbättringsförslagen behöver inte alltid generera stora resultat men de kräver inte heller några stora mängder resurser för att implementera. Men fördelen är att i slutändan kan alla förbättringsförslag tillsammans ge stora effekter.

    Fortlevnadssignaler före verksamhetens upphörande: En studie av svenska aktiebolag2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Thousands of business failures end every year, which leads to consequences for both the company itself, stakeholders and society. The need to be able to detect warning signals before the bankruptcy is an actuality and the need to at least bate the negative consequences which follows due to the business ceases is huge. Swedish auditors have, according to the law, an obligation to evaluate a company’s going concern status. They also have the obligation to do a listing in the audit report if the company has a lack of capital. The going concern warning is the auditors warning signal for stakeholders and the governments warning signal is the requirement of balance sheet for liquidation purposes when a company has a lack of capital.

    Previous studies in the field has focused on financial warning signals and the reasons why the auditors’ accuracy in issuing the going concern warnings varies. This study focuses on going concern warnings and the listing about balance sheet for liquidations purposes. The purpose of the study is to identify the existence of going concern warnings and to increase the insight into the non-financial bases behind a going concern warning. The method of the study is of a quantitative nature and examined the last three audit reports of all companies which business failure ended in 2018.

    The content in the audit reports were studied to find going-concern warnings and listings about balance sheet for liquidation purposes, this information was later the basis for summaries, calculation and analyses. The study indicates that the presence of a listing regarding balance sheet for liquidation purposes are more frequent than the going-concern warnings from the auditor. The financial reasons behind a going concern warning is more frequent than the non-financial reasons. Going concern warnings and listing of balance sheet for liquidation purposes are in some cases visible as early as three years before the business ceases.

    Semantic Segmentation of Iron Ore Pellets with Neural Networks2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This master’s thesis evaluates five existing Convolutional Neural Network (CNN) models for semantic segmentation of optical microscopy images of iron ore pellets. The models are PSPNet, FC-DenseNet, DeepLabv3+, BiSeNet and GCN. The dataset used for training and evaluation contains 180 microscopy images of iron ore pellets collected from LKAB’s experimental blast furnace in Luleå, Sweden. This thesis also investigates the impact of the dataset size and data augmentation on performance. The best performing CNN model on the task was PSPNet, which had an average accuracy of 91.7% on the dataset. Simple data augmentation techniques, horizontal and vertical flipping, improved the models’ average accuracy performance with 3.4% on average. From the results in this thesis, it was concluded that there are benefits to using CNNs for analysis of iron ore pellets, with time-saving and improved analysis as the two notable areas.

    Jämställdhet inom revisorsprofessionen: Bidrar revisionsbyråernas reella jämställdhetsarbete till en ökad jämställdhet?2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Revisorsprofessionen är en profession som under en längre tid verkat som ett manligt reservat. Problematiken som infinner sig inom revisorsprofessionen är emellertid att den är könssegregerad. Kvinnorna finns främst representerade på lägre positioner.

    Revisionsbyråerna hänvisar ojämställdheten till den inbyggda trögheten och lutar sig tillbaka på tillförligheten att framtiden kommer medföra en jämställd revisorsprofession.

    Professionen har under det senaste decenniet mottagit ökade krav på att integrera ett jämställdhetsarbete i den dagliga verksamheten. Studien ämnar därav att undersöka, bidrar revisionsbyråernas reella jämställdhetsarbete till en ökad jämställdhet?

    Syftet med studien är att skapa en förståelse för revisionsbyråernas jämställdhetsarbete. Vidare ämnar studien att analysera om det föreligger diskrepans mellan revisionsbyråernas dokumenterade och reella jämställdhetsarbete. Detta genom att (1) kartlägga revisionsbyråernas jämställdhetsmål samt (2) identifiera vilka tillvägagångssätt som revisionsbyråerna tillämpar, för att säkerställa att jämställdhetsarbetet leder till en ökad jämställdhet. Studien är baserad på en kvalitativ forskningsstrategi med en deduktiv ansats. Studiens empiriska data samlades in stegvis. Den sekundära data samlades in genom att observera revisionsbyråernas hållbarhetsredovisningar. Den primära data samlades in genom sex stycken semistrukturerade intervjuer med auktoriserade revisorer, varav två kontorschefer. Studien pekar ut en huvudsaklig slutsats om revisionsbyråernas jämställdhetsarbete.

    Slutsatsen är att det föreligger en diskrepans mellan de stora revisionsbyråernas centrala jämställdhetsplaner och jämställdhetsprocesser .Den identifierade diskrepansen uppenbarar sig mellan de byråinterna faktorerna och jämställdhetsprocesserna.

    Förslag till vidare forskning är att undersöka vilka tillvägagångssätt som revisionsbyråerna kan tillämpa för att integrera jämställdhetsprocesserna i den dagliga verksamheten.

    Reverse Logistics for Lithium-ion Batteries: A study on BPEVs in Sweden2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In recent years the amount of newly registered electric vehicles, hybrid electric vehicles, and plug-in hybrid electric vehicles has increased rapidly in the Swedish market. These vehicles could be classified as battery-powered electric vehicles, and a majority carry a lithium-ion battery. The demand for lithium is expected to increase considerably, as a result of such a swift growth in battery-powered electric vehicles. Thus, if the recycling rate of lithium stays at a low level, demand could reach a scarcity-level by 2050. While neither any infrastructure nor an established process for recycling lithium-ion batteries currently exists in Sweden, this study aims to provide necessary input and verified tools for the design of a future reverse supply chain for discarded lithium-ion batteries in Sweden.

    The literature review of this study covers the subjects of reverse logistics, supply chain network design, and operations research. A thorough situation analysis of the Swedish market for battery-powered electric vehicles is conducted, and the composition, function, and characteristics of lithium-ion batteries are studied. The study finds that estimations of future demand of recyclable lithium-ion batteries in Sweden could be between 206 711 and 726 974 tons accumulated, based on actual and predicted sales numbers until 2030. Even if it is obvious that there are going to be large quantities of such batteries requiring recycling in the future, and even if some established processes exist, there is no defined supply chain for the collection of those batteries. Finally, a mixed-integer programming model for the design and development of a future reverse supply chain is presented. The model, characterized as a discrete multi-period facility location/allocation model, can with minor modifications be used for problems with fluctuating demand or when the demand is assumed to slowly progress until it has reached a steady state.

    Tillit, styrning och service: En kvalitativ studie av Skatteverkets implementering av tillitsbaserad styrning2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Since the 1980’s, the New Public Management (NPM) has been the dominating management control philosophy in the Swedish public sector organizations. NPM has predominantly been associated with management by objective and has been expected to increase efficiency within public sector organizations. Today the control system in Swedish public sector organizations is undergoing reform with a new system called trust-based control. The foremost purpose of this new control system is to increase trust within the professions and to the citizens. This study is a qualitative case study of the Swedish Tax Agency’s implementation of the trust-based control system and the challenges that this implementation entails. The study was conducted at the Swedish Tax Agency’s office in Luleå, where managers and employees were interviewed in two stages. A thematic analysis was applied to process the data, in which four main themes appeared; team-based mode of operation, employee responsibility, customer perspective and performance evaluation. The main conclusions of the study are that the Swedish Tax Agency’s interpretation of trust-based control is a team-based mode of operation. The implementation process has been primarily decentralized, with some aid from Susan A. Wheelan’s four-stage model. Furthermore, it is concluded that the foremost challenge with implementing trust-based control is to adjust the performance evaluation to fit the new mode of operation.

    Ekonomutbildningens relevans för arbetsmarknaden: En kvalitativ studie ur olika intressentperspektiv2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Labor market in business administration is facing many changes. It is argued that the education is not matching the labor market in business administration and furthermore not keeping up with the changes. Therefore, a discrepancy exists between the employers' demand and the competencies available. The latter is especially true for recently graduated students. The purpose of the study is to examine what expectations various interest groups have on the financial education and to create an understanding of how relevant newly graduated economists’ knowledge are to the labor market, and how employable university-educated students in business administration are after their education. To achieve the purpose, we propose a theoretical framework based on previous research. This creates an understanding of the business administration educational programs and the education gap that exists today and intends to demonstrate the different criteria for employability. In addition, stakeholder theory is presented, which shows that different stakeholders have different views of university education. To fulfil the purpose of the thesis, the work has used a qualitative method in which interviews were conducted with students, alumni, teachers and employers in order to get different stakeholders' views on the topic. The work has been based on an interpretive approach to interpret the informants' perception of the relevance of financial education. An interpretive analysis was subsequently used to analyze the respondents' answers. In this way, insights and thoughts could be identified that were interesting to answer the research question: How relevant is the financial education for the labor market and how does the content of education affect the graduates' employability? The result shows that the answer to the question depends on who you ask. The relevance of the education depends on the expectations of the various stakeholders on the education. Thus, an expectation gap was proven valid rather than an education gap. The university has not managed to communicate its purpose to its stakeholders. A clearer positioning regarding the financial education and its purpose could lead to the expectation gap decreasing both for students and employers. At the same time, the value of a university education, which is now difficult for stakeholders to see, should increase.

    Revisorers syn på EU:s revisionspaket: En studie om regelverk och prissättning av revisionstjänster2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Purpose - Previous studies suggest that regulatory changes result in an increased audit effort. Given a competitive market setting and audit price negotiation between the auditor and the auditee, it is unclear if an increased audit effort results in higher audit prices. The purpose of this study is to provide the reader with a deeper understanding concerning pricing of audit services. Moreover, we examine if the EU audit reform package, comprising of Directive 2014/56/EU and Regulation (EU) No 537/2014, has had an impact on audit prices.

    Method - This study was conducted through semi-structured interviews with public authorized accountants from Big 4-firms in order to gain a deeper insight in audit pricing and the EU audit reform.

    Results - The results in this study show that audit effort has increased as a result of the EU audit reform. In addition, this study provides some support that the increase in audit effort has resulted in higher audit prices.

    Conclusion - Our main conclusion in this study is that the EU audit reform has resulted in higher audit prices, despite indications that an increased audit effort does not necessarily result in higher audit prices. The main reason behind this uncertainty is due to factors such as the competitive market setting and price negotiation.

    Den sjungande trummisen: Att spela trummor och sjunga samtidigt2019Independent thesis Basic level (degree of Bachelor of Fine Arts), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Under de senaste åren har jag börjat sjunga mer och mer samtidigt som jag spelar trummor. Framför allt förekommer detta vid speljobb utanför universitetet som after work, after ski, bröllop och andra underhållningsjobb. Min huvudsakliga funktion vid dessa typer av jobb är att spela trummor men jag blir ofta ombedd att sjunga också. Då i form av bakgrundskör. Syftet med den här undersökningen är att utveckla min förmåga att sjunga och spela trummor samtidigt. Efter undersökningen är förhoppningen att jag ska ha hittat en metod som fungerar bra för mig. Jag har studerat tre olika låtar, vardera med en egen instuderingsmetod. Låtarna har sedan spelats in för att jämföras mot varandra. Mina upplevelser under genomförandet av de olika låtarna kommer i arbetet att jämföras för att hitta en bra instuderingsmetod för sång och trummor. I slutändan diskuterar jag vilken instuderingsmetod som fungerat bäst och varför, hur sången och trumspelet har påverkat varandra och vad för svårigheter jag har stött på under arbetets gång.

    Leder hållbarhetsredovisning till prestation?: En kvantitativ studie inom Energibranschen i Sverige2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Studien syftar till att förklara hur de miljömässiga, sociala och ekonomiska målen som framställs i hållbarhetsredovisningen påverkar prestation. Vidare ämnar studien undersöka svenska företag som är verksamma inom energibranschen. Detta är en bransch med stor miljöpåverkan. Hållbarhetsprestation, allmän prestation och tillväxt var de mått som mättes för att studien skulle uppfylla sitt syfte. Studien besvarar forskningsfrågan: På vilket sätt kan hållbarhetsredovisning bidra till att företag inom energibranschen i Sverige uppnår högre prestation? Den teoretiska referensramen låg till grund för framställningen av studiens hypoteser. Dessa testades sedan empiriskt med hjälp av data som samlades in genom en kvantitativ metod i form av en enkätundersökning. Data analyserades både genom en korrelationsanalys, en variansanalys samt regressionsanalyser. Analyserna bidrog till att studiens hypoteser kunde bekräftas eller förkastas. En hållbarhetsredovisning ska främst presentera ett företags arbete med de miljömässiga, sociala och ekonomiska aspekterna av dess verksamhet. I resultatet presenteras att de tre dimensionerna av hållbarhetsarbetet har en relation till hållbarhetsprestation. Ju mer företagen arbetar med hållbarhetsmålen desto högre hållbarhersprestation kan de uppnå. För att företagen ska uppnå hållbarhetsprestation på lång sikt måste de följa upp deras uppnådda hållbarhetsmål och utvärdera dessa. Däremot har energiföretagen ännu inte lyckats implementera hållbarhetsarbetet i affärsmodellen så att de även uppnår högre allmän prestation och tillväxt. Studien visar även på att den miljömässiga hållbarheten är prioriterad bland företagen inom energibranschen.

    Kravprofil för basketlandslagsungdomar i Sverige: en deskriptiv studie2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Introduktion/bakgrund: Genom att testa basketspelarens fysiska prestation belyses eventuella brister och förenklar skadepreventionsarbetet för fysioterapeuter. Alla ungdomslandslagsspelare mellan 16-20 år kallas av Svenska basketbollförbundet (SBBF) för att göra Fysprofilen. Det saknas kravprofil baserat på ungdomars prestation, vidare behövs en kravprofil utifrån tidigare ungdomslandslagsspelares testresultat. Syfte: Syftet med studien var att beskriva hur de svenska ungdomslandslagsspelarna i baskets kravprofil ser ut i styrka, kondition och power beroende på deras längd, kön och landslagskategori; U16, U18 samt U20. Metod: 1343 ungdomslandslagsspelare i U16, U18 och U20 som testats i Coopers, knäböj, bänkpress, CMJ (a), 30m sprint år 2005-2017 inkluderades. Testresultaten bearbetades i Microsoft Office Excel och samlades in av en anställd åt SBBF. Datan avidentifierades innan det nådde författarna. Resultat: Resultatet har ställts upp i fem tabeller . Generellt sett var de längre personerna svagare, sprang långsammare och hoppade kortast jämfört med de korta både för herrarna och damerna. Standardavvikelsen var stor för alla grupper i alla test. Konklusion: Det behövs en kravprofil som är anpassad efter landslagsungdomarnas fysiska kapacitet som är uppdelad efter de olika positionerna i basket.

    Cultural Impacts on the Managing of Knowledge Sharing Processes: A Qualitative Study of Swedish Banks in Shanghai, China2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The globalization of economies and the technology development have both increased opportunities to businesses as well as challenges. Multicultural workforces and other values in the market compared with the home market lead to complexity in the management control when a business establishes abroad. Individuals’ nationalities impact their behaviors and values and it is the management’s task to coordinate the members’ activities in a way that is beneficial for the company. The banking industry is a knowledge-intensive industry, meaning the employee’s knowledge is the bank’s biggest resource. To create organizational knowledge, it is important that the knowledge is shared within the company. Effective knowledge sharing is hard to accomplish in a multicultural company since it is depending on communication between the employees which can be aggravated by cultural differences. The more distant the involved national cultures are, the harder it will be to achieve intercultural communication.

    The Swedish culture is very different from the Chinese culture. China’s economy has developed fast since it opened up to the world market in the 70’s. Today, several Swedish companies are established in China. The purpose with this study is to examine how the Chinese culture impacts Swedish knowledge-intensive companies established in China and to increase the understanding on how to overcome the cultural barriers that are affecting the managing of knowledge sharing. Cultural clashes can imply risk to a company if they affect the efficiency of the internal processes and must therefore be avoided. This field study was conducted in Shanghai, China at Swedish banks to see how they worked with the cultural differences.

    Interviews were made with staff of both Chinese and Nordic heritages to see how the cultural differences impacted their operations. The results showed that there are several cultural clashes that affect effective knowledge sharing processes within the companies. The management tries to implement the Swedish way of working in the branches, but the Chinese culture has a strong impact on the communication channels and it creates confusions and misunderstanding between the Nordic and Chinese employees. Cultural understanding and adjustment to the cultural conditions have been shown from earlier researches to reduce cultural clashes. This study supports those arguments by showing that a higher level of intercultural communication leads to increasing cultural understanding and a quicker adjustment to the organization’s way of working. The study also showed that the national culture’s impact on individual behavior was stronger to individuals that have had less foreign exchanges. The study contributes with suggestions of enlightening cultural differences more by formal meetings to increase the cultural understanding within the companies, as well as intercultural team works over department units should be implemented.

    Arbetsterapeuters erfarenhet av att använda bedömningsinstrument2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Aim: The aim of the study was to describe occupational therapists’experience of using assessment tools. Method: The study was conducted with a qualitative data collection method where ten occupational therapists were interviewed. During the interviews, a semi-structured interview guide was used. When analyzing the collected data, a qualitative analysis was used. Result: Based on the analysis, four categories emerge that describe the occupational therapists' experience of using assessment tools. The categories Time and Knowledge, Clients'Different Needs, Structure and Clinical Experience, and Assessment Tools and the Incompatibility of the Journal Systems show a result that indicates a high workload within the profession. This study reveals a new finding that describes how occupational therapists also exclude assessment tools, since they do not see the assessment toolsas compatible with the medical record system, which contributes to the fact that occupational therapists experience great difficulties in documenting their assessments in a structured and time-efficient manner. Conclusion: From the results presented in the study, it is concluded that occupational therapists today need more time allocated in their work to enable the use of assessment tools. This is to be able to increase theirknowledge of assessment tools, but also to be able to administer them in the intended way, mainly regarding the documentation and medical record keeping

    Kartläggning av samband mellan användningen av Instagram i relation till träningsberoende, träningsvanor och ortorexia nervosa bland aktiva unga vuxna: En enkätstudie2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Introduktion: Idag blir allt fler människor mindre fysiskt aktiva, trots detta ökar utvecklingen av träningsberoende. Fysioterapeuter kan träffa personer med träningsberoende genom att de fått en skada på grund av sitt beteende. Därmed är det viktigt att fysioterapeuter har kunskap om träningsberoende och dess drivkraft. Användningen av sociala medier har ökat markant de senaste åren. En trend som ökat på Instagram är publicering av träningsrelaterade bilder. Publicering av sådana bilder, ökar pressen hos användaren på hur man bör se ut, vilket medför missnöje, ångest och andra negativa tankar. Syfte: Studiens syfte var att kartlägga samband mellan användningen av Instagram i relation till träningsberoende, träningsvanor och ortorexia nervosa bland aktiva unga vuxna mellan 18-24 år. Metod: En webbenkätundersökning gjordes för att besvara syftet. Enkäten skapades med inspiration från olika mätinstrument: IPAQ, EAI och ORTO-15. 47 svar analyserades. Resultat: Det fanns en koppling mellan mer användningstid och att följa träningskonton på Instagram, i relation till hög risk att utveckla träningsberoende. Det fanns också en korrelation mellan fler antal träningstimmar och risken att utveckla träningsberoende. Ingen korrelation visades mellan antalet träningstimmar och risken att utveckla ortorexia nervosa. Kvinnor hade högre risk att utveckla träningsberoende medan män hade högre risk att utveckla ortorexia nervosa. Konklusion: Koppling fanns mellan variablerna: användning av Instagram, risk att utveckla träningsberoende, träningsvanor och risk att utveckla ortorexia nervosa. Denna studies resultat kan vara påverkat då ett litet urval studerats. Mer forskning behövs inom området.

    Think outside of the box(es)!: En studie kring en okonventionell metod för improvisation på elgitarr2019Independent thesis Basic level (degree of Bachelor of Fine Arts), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Detta arbete handlar om min resa mot en friare improvisation genom att bryta ner gitarrhalsen i mindre beståndsdelar och lokalisera grundtoner och visualisera intervall utifrån dem med hjälp av den metod som jag kallar för den”intervalliska metoden”. Det ville jag göra för att frångå de mönster och boxar som jag vanligtvis använder mig av, vilket är en metod som kallas för ”caged-metoden”. I arbetet beskrivs det hur jag steg för steg jobbar med olika moment, övningar, analyser och hur jag tar mig an utmaningar för främjandet av min utveckling. Under processens gång presenterar jag vitala element som var tvungna att falla på plats för att jag skulle nå ett lyckat resultat. Jag demonstrerar arbetet till stor del med hjälp av visuella medel, så som notbilder och filmer för att stödja min forskning. Arbetet resulterade i en bättre förståelse för harmonik, ökad säkerhet och kontroll i att konstruera melodier och rent generellt ett starkare improvisatoriskt fundament.

    Implementation of Hydro Power Plant Optimization for Operation and Production Planning2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Output power of hydro power plant was modelled and an optimization algorithm was implemented in a tool for optimizing hydro power plants. The tool maximizes power output of a hydro power plant by distributing water over a set of active units in the power plant which will be used in planning of electricity production. This tool was built in a MATLAB environment, using the optimization toolbox, and a GUI was developed for Vattenfall. The optimization tool was based on the same architecture as the current tool used for this kind of optimization which is to be replaced by the work presented in this thesis. Therefore, the goal was to achieve the same optimal results as the current optimization tool.

    Power output of three of Vattenfall’s hydro power plants were computed and two of these plants were optimized. These power output results were compared to results from the optimization tool currently used. This showed differences within the inaccuracy of measurements of ≤ 0.3%. These three power plants proved that the new tool is sufficient to replace the current tool but further testing is recommended to be conducted on more of Vattenfall’s hydro power plants to prove its consistency.

    Arbetsterapeuters erfarenheter av samtal om levnadsvanor2019Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study was to examine occupational therapists experiences of health-promoting dialogue. Today, there is no research that shows the importance of the health-promotion dialogue as an individual factor of change in occupational therapeutic treatment. The study was conducted with a qualitative approach in which the authors conducted ten semi-structured interviews with occupational therapists, working in municipal health care and was active in the south and middle part of Sweden. A qualitative content analysis with an inductive approach was used for the study. This resulted in the following categories; Health promoting or health informative counselling; The environmental dimensions effect on the counselling and Lifestyle habit as everyday habit. The first category indicated that health-promoting dialogue seldom originated from an evidence-based method and had a promoting or informative approach, depending on the level of counselling competence of the occupational therapist. The second category showed that the environmental dimensions played an important role in counselling implementation as well as for the outcome, but seldom supported it. The third category showed that the occupational perspective effected the counselling process, based on its focus on occupation as a therapeutic mean. The study identified multiple promoting and limiting factors which effected the occupational therapists health-promoting dialogue. The authors conclude that this knowledge would contribute to improve the quality in the health-promoting dialogue process of the occupational therapist. This study shows how competence, environment and the occupational perspective constitutes crucial and cooperative factors for the potential change in the health-promoting dialogue.

    Smartphone inom rehabilitering för personer med förvärvad hjärnskada: En litteraturstudie2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Aim: The aim of this literature study was to describe how the smartphone is used as a compensatory aid in rehabilitation and the importance it can have for people with acquired brain injury.

    Method: To answer the purpose, a literature study was carried out which included qualitative and quantitative research based on eight studies.

    Result: The smartphone has many advantages as a compensatory aid and it shows important for people with acquired brain injury in their daily life in many ways. Significant effects could be measured which led to more activities being initiated and completed at the right time, thus many of the basic problems with acquired brain injury are addressed, such as problems with memory, planning, initiation and organization. The smartphone was also preferred by the users in front of other devices.

    Conclusion: The study shows great advantages in implementing the smartphone as part of the rehabilitation of acquired brain injury. Furthermore, the study shows that the smartphone is the part of people's lives regardless of if they suffer from acquired brain damage or not. There is a need for further research within the subject since there are few studies that shed light on smartphone's as compensatory aid at present.

    Arbetsterapeuters kliniska resonemang samt erfarenheter av interventioner för att främja delaktighet i aktivitet hos barn med ADHD2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning

    Syfte: Syftet med studien var att beskriva arbetsterapeuters kliniska resonemang samt erfarenheter av interventioner för att främja delaktighet i aktivitet hos barn med ADHD. Metod: Studien var baserad på en kvalitativ ansats med semistrukturerade intervjuer för att undersöka arbetsterapeuternas kliniska resonemang och erfarenheter. Sex arbetsterapeuter från olika regioner i Sverige deltog i studien. En kvalitativ innehållsanalys användes för att undersöka erfarenheter av interventioner vilka därefter analyserades deduktivt för att identifiera kliniska resonmang. Resultat: Resultatet redovisades i ett övergripande tema; Att möta barnet och familjen i den aktuella situationen med tre kategorier; Hela familjen som klient, Kartläggning av aktivitetsutförande för en lyckad intervention och Resonemang kring yrkesetiska aspekter. Resultatet visade att klientcentrering var kärnan i deltagarnas kliniska resonemang där empati, samarbete och kommunikation var viktiga aspekter att resonera kring. Deltagarnas erfarenhet var att det mest betydelsefulla för att främja delaktighet i aktivitet hos barn med ADHD var inlärning av strategier för att hantera barnets begränsningar i vardagen. Utöver det var olika former av kognitivt stöd vanligt förekommande interventioner. Slutsats: Studien har bidragit till ökad insikt i arbetsterapeuters erfarenhet av interventioner i arbetet med barn med ADHD samt en ökad förståelse för arbetsterapeuters kliniska resonemang.

    Perceived Audio Quality In Popular Music Encoded To MP3 And Opus2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    For storage restriction purposes, audio streaming services often rely on lossy compression formats as files used for playback. In 2018, the audio streaming giant SoundCloud went from using 128 kbps MP3 files to 64 kbps Opus files, and shortly after this was unveiled, music press and users of the service claimed it to be an audio quality impairment. To investigate the reliability in these claims, listening tests using popular songs were performed, having 17 trained listeners assessing perceptual audio quality in 128 kbps MP3 and 64 kbps Opus compared to 44.1 kHz, 24 bit WAV files. When counting scores of all used audio stimuli combined, results showed MP3 outperforming Opus with statistical significance.

    Internationalization challenges among born globals: A roadmap for higher success2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Purpose – The purpose of this study is to advance the understanding of

    internationalization among born global companies. In order to fulfil the purpose, three

    foreign market entries were investigated at a Swedish born global that offers digital

    streaming services for audiobooks.

    Method – We conducted a qualitative single case study with a grounded theory approach.

    The main data was collected through 22 interviews and 13 documents. The data analysis

    was two-folded; 1) content analysis for charting the market entries, and 2) thematic

    analysis for identifying challenges and how to address these.

    Findings – Our findings is divided into three parts. First, we present five challenges that

    born global companies might experience when they enter new foreign markets. These

    five challenges are sorted as primary; 1) lack of networks, 2) new-to-the-world, and 3)

    lack of partnerships, and secondary; 4) lack of market-specific knowledge, and 5) lack of

    support. Second, we provide eight actions that can be addressed to either one or more of

    the five challenges. The two actions that are most significant, i.e. can address the most

    challenges are; 1) utilize established investor, and 2) hire local and experienced employee

    on-site. Finally, the two research questions are compiled into a roadmap that provides a

    start-to-end guide for how conquer challenges for internationalization.

    Theoretical and practical implications – This study contributes to current

    internationalization literature by extending the view of born globals’ internationalization

    process. More specifically, it provides knowledge about possible challenges and how to

    address them, which previous literature has not explored. We believe that born globals

    can use the developed roadmap to increase their success rate. We also believe that the

    newly identified challenges can be used as a complement to the already explored success

    factors, in order to provide managers at born globals with a more holistic view of how

    to succeed with their internationalization journey.

    En genomtänkt vinterresa: En tolkning av pianostämman i två sånger ur Schuberts Winterreise2019Independent thesis Basic level (degree of Bachelor of Fine Arts), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Jag vill som klassisk pianist bli bättre på att tolka sång- och pianomusik eftersom jag spelar mycket tillsammans med sångare i vardagslivet. Jag har valt två sånger ur sångcykeln Winterreise som jag har analyserat för att komma fram till en tolkning som jag kan argumentera för.

     

    Jag har analyserat sångerna med not- och harmonianalys och jag har skrivit framförallt om något oförväntat eller nytt händer i musiken. När jag kände att jag undersökt partituren noga så började jag hänvisa till texten.

    Med arbetet har jag besvarat mina tre frågeställningar: Hur påverkar en djupare förståelse av Die Krähe och Frühlingstraum arbetet med musikaliska uttryck i de två sångerna? Hur tolkar jag kopplingen mellan texten och pianostämman i olika avsnitt? Hur får jag pianostämman att uttrycka detta?

    Nu i efterhand så har jag en inblick hur jag ska gå tillväga när jag ska tolka sång- och pianorepertoar. Min tidigare kunskap inom musikteori var ganska begränsad och detta arbetet har hjälpt mig att utvecklas.

    Electronic structure calculations of defects in diamond for quantum computing: A study of the addition of dopants in the diamond structure2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    When doing computations on the negatively (positively) charged NV-center in

    diamond, the common procedure is to add (subtract) an electron from the system.

    However, when using periodic boundary conditions, this addition/subtraction of an

    electron from the supercell would result in a divergent electrostatic energy. So an

    artificial background jellium charge of opposite charge that compensate the electronic

    charge to make the supercell neutral is needed. This introduces further problems that

    needs corrections. And this method is especially problematic for slab supercells, as the

    compensating background charge leads to a dipole, which diverges as the vacuum

    between the slab images increases. An alternative, recently proposed way of charging

    the NV-center is to introduce electron donors/acceptors in the form of nitrogen/boron

    atoms (at substitutional sites in the diamond lattice). In this way, we keep the

    supercell/slab neutral, and avoid correction schemes. In this work we verify that the

    addition of a substitutional nitrogen atom indeed has the same effect on the NV-center

    as the more traditional method of adding an extra electron to the system. Further, we

    investigate the effects of 1. Adding two substitutional nitrogen atoms to the system (3

    nitrogen atoms in total, neutral supercell), 2. Adding a substitutional nitrogen atom and

    an electron to the system (2 nitrogen atom in total, negatively charged supercell), 3.

    Adding two electrons to the system (1 nitrogen atom, doubly negatively charged

    supercell). Additionally, we investigate the addition of acceptor dopants (boron) in

    order to analyze the effect on the electronic structure of the NV-center and diamond.

    Design for Addressing Data Privacy Issues in Legacy Enterprise Application Integration2019Independent thesis Advanced level (degree of Master (Two Years)), 80 credits / 120 HE creditsStudent thesis
    Abstract [en]

    Electronic message transfer is the key element in enterprise application integration (EAI) and the privacy of data transferred must be protected by the systems involved in the message transfer from origin to the destination. The recent data privacy regulation such as GDPR (General Data Protection Regulation) has enforced the organizations to ensure the privacy of the personal data handled with obligations to provide visibility and control over to the data owner. Privacy concerns with relevant to sensitive data embedded and transferred through business-to-business (B2B) middleware platforms in enterprise architecture are mostly at risk with the legacy nature of the products and the complexity of system integrations. This poses a great threat and challenge to organizations processing sensitive data over the interconnected systems in complying with regulatory requirements. 

    This research proposes a solution design to address the data privacy issues related to personal data handled in an enterprise application integration framework. Where electronic messages used to transfer personally identifiable information (PII). The proposal consisting of a design called “Safety Locker” to issue unique tokens related to encrypted PII elements stored in a persistence data storage based on Apache Ignite. While adding REST API interfaces to access the application functionality such as tokenization, de-tokenization, token management and accessing audit logs. The safety locker can run as a standalone application allowing clients to access its functionality remotely utilizing hypertext transfer protocol (HTTP). The design allows the data controllers to ensure the privacy of PII by embedding tokens generated from the application within the electronic messages transferred through interconnected systems. The solution design is evaluated through a proof of concept implementation, which can be adapted, enhanced to apply in EAI implementations.

    Förekomst och självskattad upplevelse av arbetsterapeutiska interventioner för kvinnor med stressrelaterad ohälsa2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Mental ill-health is today the most common cause of long-term sick leave in Sweden and stress-related diagnoses account for 49 percent where women are over-represented. The consequences of stress-related ill-health leads to difficulties in everyday life. Where a subjective experience of incongruence between requirements and ability in occupational performance and an imbalance in activity patterns are crucial. Having a balanced activity pattern and experiencing congruence in occupational performance are considered to be essential for experiencing participation and health in occupational therapy theory. The purpose of this study was to explore the incidence of occupational therapy interventions for women with stress-related disorders and their self-rated experiences of the interventions. The method used was a quantitative cross-sectional study where data from 188 women were collected using a self-designed web survey on the social network Facebook. The questionnaire concerned demographic data and the incidence and self-rated experience of seven occupational therapy interventions. The result showed that 37 percent of the respondents had received some form of occupational therapy intervention and on average 2.5 interventions per respondent. There were no statistical regional differences in the incidence of occupational therapy interventions. The most common intervention was Strategies for managing stressful situations (31%). The intervention Workplace adjustments of performance and environment rated highest where 13 out of 14 women (93%) rated Very good/Fairly good. Overall the occupational therapy interventions where rated as Very good/Fairly good (80%). Conclusion: The overall result showed that occupational therapy interventions occurred only among approximately one-third of the women who sought care related to stress-related disorder. However, the majority considered that their experience of the interventions were positive, which indicates that occupational therapy interventions can be a support in the rehabilitation of women with stress-related disorders.

    Nyblivna pensionärers upplevelse av hälsa och aktivitetsbalans i vardagslivet2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning

    Vid pensioneringen har personen lämnat sitt arbete som kan ha varit den största aktiviteten i vardagen. Det blir en omställning som kan leda till både förändrad hälsa och inverka på aktivitetsbalansen. Syfte: Studiens syfte var att undersöka hur nyblivna pensionärer upplever sin hälsa och aktivitetsbalans i vardagen. Metod: Semistrukturerade intervjuer genomfördes med 12 nyblivna pensionärer. Intervjuerna genomfördes gemensamt av författarna med en deltagare åt gången. De transkriberade intervjuerna analyserades i två domäner med kvalitativ innehållsanalys vilket resulterade i totalt fem kategorier. Resultat: Översiktligt visade resultatet att övergången till pensioneringen i huvudsak var positiv men det fanns även en saknad efter tidigare arbetskamrater och strukturen de hade när de arbetade. Resultatet visade två domäner med kategorier. Domänen Hälsa med kategorierna: Kroppens styrka och Positiv och negativ energi. Det centrala inom domänen Hälsa visar att fysisk kapacitet och att ha energi till att utföra meningsfulla aktiviteter ger en god hälsa. Socialt nätverk, sjukdomar och väder är aspekter som påverkar hälsan. Domänen Aktivitetsbalans beskrevs inom kategorierna: Självbestämmande utan tidspress, Variationer i aktivitet och Stressorer som påverkar.  Det övergripande inom domänen Aktivitetsbalans visar att deltagarna uppfattar sig ha aktivitetsbalans när de har en självbestämmande vardag utan tidspress. Slutsats: Slutsatsen är att deltagarna upplever hälsa och aktivitetsbalans i vardagen när de har energi och fysisk kapacitet för att kunna utföra självbestämmande och meningsfulla aktiviteter utan tidspress. Med kunskap från aktuell studie och mer forskning kan arbetsterapeuter med en ökad förståelse vägleda individer i övergången till pension och ge stöd till att implementera meningsfulla aktiviteter.

    Abstract [en]

    The purposeof the study was to investigate whether occupational therapists find that therapy dogs can affect the relationship with the client and client´s participation in activity. The methodused was a qualitative study with ten participants who were contacted via recommendations and via the social network Facebook. The questions concerned the occupational therapists' experience of working with therapy dogs and their experiences of whether the therapy dog ​​can be a tool to help create relationship with the client and motivate for activity. The resultshowed that the experience was predominantly positive and that the therapy dog ​​made the client contact stronger. The occupational therapists experienced that they could go further in their interventions with the help of the dog and that the clients opened up more and were more motivated to participate in activities when the dog was present. It also showed that education, planning, goal setting and journaling were important to demonstrate the effect of therapy dogs. Conclusion:The result showed positive situations in which the therapy dog ​​was an aid for the occupational therapists' success in the intervention. The study showed that contact with the client was strengthened with the help of the therapy dog ​​and that the motivation to participate in activities increased.

    Online Communication and Brand Attitudes: A Millennial Perspective2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study’s purpose was to provide a deeper understanding regarding how millennials’ attitudes towards brands are influenced by online communication. With the aim of fulfilling the purpose of the study, two research questions of descriptive and explorative kind were stated; “How can the factors that influence millennials’ use of electronic word-of-mouth be described?” as well as “How does electronic word-of-mouth influence millennials’ brand attitude?”. In order to generate potential answers to the stated research questions, a conceptual framework was conducted by reviewing scholarly literature. The conceptual framework then provided the study with a theoretical foundation of which was utilized during both the data collection and the data analysis. Methodologically, this was a case study analyzing qualitative data that was collected through eleven semi-structured and in-depth interviews with both male and female millennials. The findings and conclusions of this study implied that electronic word-of-mouth has a meaningful impact on both the formation of and influence on attitudes towards brands amongst the millennials. Moreover, this was heavily dependent on the one disseminated it. However, with regard to the ever-evolving area of social network sites, other noteworthy factors such as millennials’ need for affiliation, aesthetically appealing firm-generated content and intense exposure to digital advertising were emphasized as components of which too formed their attitudes towards brands. Furthermore, the results suggested that adopting personalization- and social interaction strategies will encourage the spreading of positive electronic word-of-mouth. Lastly, positive electronic word-of-mouth was then for its part related to brand loyalty, which was reckoned to promote the persistency of positive brand attitudes.

    Föräldrars upplevelser av att ha barn med psykiska och/eller kognitiva svårigheter i skolan2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of the study was to describe parent´s experiences of having children with mental and/or cognitive difficulties in school.The authors made semi-structured interviews by telephone with 10 parents who have children with difficulties in school. Data was analyzed according to a qualitative content analysis. The analysis resulted in the following categories  parents need to be the spider in the network, the frustration of not getting enough support, the school environment's impact on the children, the feeling of not knowing what is happening and positive experiences of the school. The result of the study showed that parents find that there are deficiencies in the school environment that affect the children in their activity performance. The parents feel that there is no important knowledge among the educators, which gives them the opportunity to support their children in the right way so that the children have the same opportunities as the other children at the school. The authors of the study discuss the results based on what occupational therapists can contribute for knowledge to the pedagogues and support the children in achieving the best possible results in schoolwork. Continued research on this subject could be about the experience of fathers and the school's experience of having children with difficulties in school.

    Identifiering av slöseri och undersökning av multipla takttider: En studie på ABB Robotics2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    ABB Robotics is one of the largest manufacturer of industrial robots on the global market. One of their factories is located in Västerås where this work was executed at the final assembly line for large industry robots (SSIR).

    The final assembly line have recently been converted to a takted one-piece flow. Now ABB Robotics want to identify waste in the new assembly line and investigate the possibility to use multiple takt times to increase their capacity. The project was divided into two parts where the first part was assigned to identify waste and the second part to analyze the use of takt time.

    A current state mapping was performed to increase the understanding for the flow and the issue. Value stream mapping (VSM) was executed in an existing template with the use of data from the current state mapping and cycle times from recent time studies. Waste was identified according to lean with the help of VSM, spaghetti diagram and the disruption log. Today waste arise from the worker having to move to collect tools and material. Cycle times used for the VSM were later on used for calculations regarding capacity and takt time. Different takt times and mix of models were compared to give recommendations regarding the use of multiple takt times.

    Solutions on how to decrease and measure waste was presented. Two of the solutions were to change layout of station 1 and to implement a new materials feed system.

    With todays cycle times ABB Robotics are recommended to only use one takt time. The same goes for the case when the cycle times are shortened evenly. If the gap between the average cycle time for heavy models respectively light models would increase, then it would become interesting to further investigate the use of multiple takt times. The gap would increase if the light models are rebalanced to include operations by station 2 and in this case the capacity would increase with 4,5 % with the use of multiple takt times instead of one takt time.

    Stabilisering av Aluminiumreducerad AOD-slagg.2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Slag has historically been used as a construction material in different applications. All types of slags are not suitable due to insufficient properties. Production of high alloy stainless steels leads to a slag which is rich in lime, which leads to disintegration due to absorption of water. Certain steel qualities at Sandvik is manufactured with a two slagg procedure where a first reduction slag is use that is replaced with a refining slag. This report looks into changes in the slag-composition to improve the properties in regards to volumetric stability after disposal. Especially it investigates volumetric stability of the reduction slag and if it is possible to combinea production of high quality steel with a stable slag. Further investigations during the project has looked at how the slag works today, with sampling close to the AOD converter but also how different slag compositions affects the slag that is disposed of outside the steelplant with todays disposal routine. Slag that disintegrates due to phase changes during cooling has been observed. A slag composition that seems promising from aproduction and stability perspective has been found. It results in a slag that remain stable even after enduring harsch enviroments. A production with less lime addition during the reduction phase can handle about two thirds of the aluminum reduced steel batches. With this small changein the AOD process roughly 6000tonnes/year of slag could be shifted from disintegration to stable material.

    Aktivitetsbalans hos föräldrar till barn med neuropsykiatrisk funktionsnedsättning, NPF2019Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Occupational balance is a subjective experience that includes the right amount and the right variation between activities. Having a child with NDD can have effects on how the family's everyday routines are organized and affect the parents' choice and planning of activities. Aim: Exploring occupational balance in parents to children with neurodevelopmental disorder, NDD, ages 6-12 years. Method: A quantitative survey was conducted. The web survey was designed according to the Occupational Balance Questionnaire (OBQ) and each question at the ordinal scale level was supplemented with a free text response. When analyzing data, a quantitative processing and a qualitative content analysis were applied. The study had 194 parents participating. Result: Parents estimated their occupational balance predominantly low. The result also showed that there was a significant difference between the parents' work situation and the number of children with NDD. However, the result showed no significant difference if the parents were cohabiting / married or single. In the study's content analysis three categories were identified: Restructuring of everyday life, Parent's contact with social support and The changed role as a parent. Conclusion: The parents have a consistently low occupational balance. To address the parents' need for support, occupational therapists should proceed a holistic perspective on the family in the work with children with NDD.

    Arbetsterapeutiska insatser i rehabiliteringsprocessen för individer med utmattningssyndrom och stressrelaterad psykisk ohälsa och dess effekt på återgång i arbete - en litteraturstudie2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of the literature study was to investigate when the occupational therapist becomes involved in the work rehabilitation of individuals who are sick-listed as a result of exhaustion disorder and stress-related mental health, how occupational therapy is applied and what effect occupational therapy interventions have on the client's return to work. The collection of data was done by searching the databases CINAHL, PsycINFO, Cochrane, PubMed, SveMed + and Amed via Luleå technical university library during the period February to March 2019. A total of ten articles were selected for inclusion in the study. The result show thatnone of the studies describes with clarity when the occupational therapist becomes involved in the work rehabilitation. The results regarding how occupational therapy is being used for the client group generally shows that the occupational therapist alone or in multidisciplinary teams perform interventions directed toward activity balance, primarily in the context of swedish primary care and rehabilitation clinics. The effects of the interventions on the client's return towork were presented in only three of the studies and the overall results show small effects, and the evidence presented is of low or moderate quality. The author ́s states that more research is needed on the subject and the client group, and that in future studies each professions part of the efforts need to be elucidated so that it is possible to distinguish the importance of occupational therapy for return to work.

    Welcome To The Jungle: Att som kvinnlig sångerska efterlikna ett manligt rocksångsideal2019Independent thesis Basic level (degree of Bachelor of Fine Arts), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Det här arbetet handlar om hur jag som kvinnlig sångare kan ta mig an rocklåtar som i originalet sjungs av män och ändå behålla sångframförandets karaktär. Detta utan att ta till det förväntade alternativet att byta tonart. Forskningsfrågan handlar om hur jag kan modifiera mitt normala sångsätt för att förmedla samma intensitet, känsla och sound i framförandet som i originalet som är skrivet utifrån en manlig sångröst. Detta för att se om jag kan hitta verktyg inom sång som hjälper att behålla sångens karaktär även fast originalet är skrivet utifrån en manlig sångröst. Jag valde sex låtar inom rockgenren som jag spelade in med ett band tre gånger och mellan gångerna analyserade och jämförde min sång med originalframförandet och spelade in egna inspelningar med hjälp av backing tracks för att hitta ytterligare verktyg. Den sångmässiga progressionen och användandet av olika sångtekniska verktyg presenteras både i form av ljudinspelningar och diverse notbilder. Undersökningen visade att de främsta verktygen för att uppnå detta var mörk klangfärg, effekter, utbyte av toner eller melodier, släppa kontrollbehovet, funktionen overdrive, energi, envishet, att inte glömma hur viktig fraseringen är och att komma ihåg att lyssna vad allt som finns under effekterna. Genom att applicera dessa verktyg kan en kvinnlig sångare uppnå ett resultat som är nära originalsångens karaktär även fast originalsångaren är en man. Med detta arbete hoppas jag kunna inspirera andra sångare att våga ta sig an låtar som inte ligger i deras bekvämlighetszon samt ge mig själv och andra verktyg att använda sig av vid sådana situationer.

    Att vara ung 18-30 år och leva med långvarig smärta: En kvalitativ intervjustudie2019Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Pain is a subjective experience that affects and limits the individual in different ways. It is important to make use of a holistic perspective, as a sustained pain may be due to factors other than the physiological ones. It is important as a caregiver to respond, especially to young pain patients, with a patient-centered and holistic approach. This is to early identify the pain in order to avoid the pain becoming chronic. The right treatment can also be of value for the individual's view of their pain and the future. The aim of this study was to investigate how young people between 18-30 years with long-term, non-specific pain experience their pain in relation to their everyday life, working life and the treatment from the care. The method is a qualitative interview study, with three participants living with long-term pain. After interviews, the material was processed with a qualitative content analysis. The result of the study resulted in four main categories; long-term pain, be treated as young patients, the importance of a diagnosis, the future and a number of sub-categories. It turned out that the pain has a great impact on the informants' everyday life. A confirmation from the health service could have contributed to an increased acceptance of the informants condition. The conclusion is that the pain is always true and have a great impact on life in general and should always be taken seriously, even though there is no physiological explanation for it.

    LES Modelling of Turbulent Flow Through an Array of Cylinders Using OpenFOAM2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The objective for this master thesis project was to perform simulations for high and low Reynolds number for a porousmedia modelled as quadratic packed cylinders. The simulations were to be performed by using the open source codeOpenFOAM and the turbulence should be modelled by the LES turbulence model in order to resolve details about theturbulence. In Hellström et al. (2009) simulations were performed for a similar setup but for the k-Omega SST turbulencemodel. In this project simulations were performed not only for LES but also with the k-Omega SST model and for the laminar description in order to validate the LES problem setup. For the simulations Reynolds number was calculatedbased on the porosity and the cylinder diameter and was denoted Re’. The simulations were performed for a set of Re’and for each Re’ the permeability was calculated based on Darcy’s law. The calculations of the permeability showed,in line with the results from Hellström, that at Re’ around 20 there is a drop in the permeability both for the LESand SST simulations. From the permeability simulations it was also seen that for low Re’ flows the LES and laminardescriptions agreed with each other, but that the SST simulations yielded lower values of the permeability. Accordingto Hellström the permeability drop was due to onset of inertia effects. When looking at the resulting flow field plots itgave the idea that the amount of turbulence could also have influence on the resulting permeability.

    Effekter av träningsbelastning på muskelstyrka och muskelhypertrofi: En litteraturöversikt2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Styrketräning är en vanlig motion- och rehabiliteringsform som exempelvis höjer den anaeroba uthålligheten, bidrar till hypertrofi i muskelcellerna och ökar muskelstyrkan. Fysioterapeuter instruerar, ordinerar och leder styrketräning för olika patientgrupper i alla åldrar. Det har blivit en viktig del i dagens rehabilitering. Patienter har olika förutsättningar till att styrketräna med låg- respektive hög belastning beroende på skada eller sjukdom. Syfte: Syftet med litteraturöversikten var att undersöka hur belastningen vid styrketräning påverkar muskelstyrka och muskelhypertrofi. Metod: En artikelsökning genomfördes i databaserna: PubMED, Web of Science, Cochrane Library, SportDiscus och Scopus. Relevanta ämnesord för respektive databas tillämpades. Enbart studier som jämförde låg belastning (<60% 1RM) kontra hög belastning (>60% 1RM) på utfallsmåtten styrka och hypertrofi blev inkluderade i resultatet. Resultat: Totalt blev 9 artiklar inkluderade i litteraturstudien. Artiklarna visade att muskelstyrkan ökar oavsett om träningen sker med hög eller låg belastning. Träning med hög belastning ger en större ökning av muskelstyrkan än träning med låg belastning. Både träning med hög och låg belastning gav upphov till hypertrofi. Ingen utom en av studierna kunde redovisa signifikanta skillnader i hypertrofi utifrån belastning. Konklusion Att träna styrketräning med målsättningen att öka i styrka och/eller hypertrofi går att göra genom både hög- och låg belastning. Hög belastning har större effekt på muskelstyrka och är fördelaktigt i jämförelse med låg belastning.

    Erfarenheter av utveckling inom arbetsterapi vid Arbetsförmedlingen i Sverige2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: To describe occupational therapists experiences of development in occupational therapy at The Swedish Public Employment Service. Method: The study was conducted using qualitative interviews. Thirteen occupational therapists working at The Swedish Public Employment Service participated. The occupational therapists had a geographical spread throughout Sweden. Collected data was transcribed and analysed according to qualitative content analysis. Result: Data resulted in five categories as follows: To work with development of scientific methods, Importance of feasibility to competence development, Cooperation as a part of the improvement work, Preconditions to be person-centered and Importance of continual evaluation to improve actions. The occupational therapists describes in these categories various supportive and hindering factors at to what extent they had preconditions to carry out and develop occupational therapy at The Swedish Public Employment Service. Supporting factors were described as well-developed methods, a person-centered approach and intern cooperation. Obstructing factors were described as defective coordination between social actors in the community, insufficient evaluations, limited possibilities to competence development and implementation of research. Conclusion: This study contribute to knowledge of occupational therapists preconditions to development of methods and improvement work. The study shows that it is a lack of knowledge and a need of research is required to illustrate the role of occupational therapists within vocational rehabilitation at The Swedish Public Employment Service.

    Att inkludera barn- och ungdomar med funktionsnedsättning i föreningsidrott: barn- och ungdomsledares resonemang2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte: Syftet med studien var att beskriva hur barn- och ungdomsledare resonerar kring att inkludera barn och ungdomar med funktionsnedsättning inom föreningsidrottens aktiviteter. Metod: En kvalitativ intervjustudie valdes som design där 12 barn- och ungdomsledare deltog i studien. Deltagarna var mellan 30-45 år gamla (medelålder 36,6 år) och aktiva inom föreningsidrotten sedan minst 1 år tillbaka (medelvärde 7,9 år). Studien innefattade idrotterna innebandy, fotboll, handboll, simning, gymnastik och friidrott och samtliga deltagare hade erhållit minst en ledarutbildning. Urvalet av deltagare skedde genom ett snöbollsurval med utgångspunkt i två skilda geografiska områden i Sverige. Vid dataanalysen användes en kvalitativ innehållsanalys med induktiv ansats och resultatet presenterades i tre kategorier med tillhörande underkategorier tillsammans med citat från deltagarna. Resultat: I kategorierna Individens förutsättningar och hur föräldrar och ledare påverkar möjligheten tillinkludering, Idrottens utformning och föreningars arbete kring inkludering samt Hur bemötande från omgivningen och samhällets utformning påverkar inkludering presenterades ett flertal olika förutsättningar som kan skapa möjligheter för en framgångsrik inkludering av barn- och ungdomar med funktionsnedsättning inom föreningsidrotten. I resultatet framkom bland annat att utbildning, ledares kompetens och föräldrars engagemang var viktiga förutsättningar för en lyckad inkludering. Konklusion: Studien har bidragit till en inblick kring vilka förutsättningar som främjar barn och ungdomar med funktionsnedsättningars möjligheter att delta inom föreningsidrotten. Resultatet gav indikationer på att arbetsterapeutens kompetens kan användas för att främja en möjlig inkludering för barn och ungdomar med funktionsnedsättning.

    Tillämpning av Last Planner på materialhantering:: En fallstudie på medelstora byggarbetsplatser.2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Byggnadsprojekt finns i många varianter, stora, små, enkla eller komplexa. Ett problem som är gemensamt för alla projekt är att flödet av material som ska monteras in i byggnaden ofta inte fungerar på ett bra sätt.

    Byggbranschen ligger bakom andra branscher exempelvis verkstadsindustrin när det kommer till att effektivisera och optimera processer. Under de två senaste årtiondena har tillverkningsindustrin utvecklats avsevärt inom effektivisering och produktivitet. Under samma tidsperiod har byggbranschen utvecklats väldigt långsamt. Symptomen inom byggbranschen är förseningar och budgetöverskridningar. Ett annat vanligt problem är att det under ett byggprojekt finns olika sorter av slöseri som påverkar produktiviteten negativt, exempelvis onödig väntetid, onödig lagring av material och onödiga transporter.

    I denna studie genomfördes intervjuer och platsbesök på två av Peabs arbetsplatser i Malmöregionen. Informationen från detta användes för att kartlägga flödet för fyra vanligt använda material, fönster, gips, kök och innerdörrar. Efter att flödet kartlagts användes Lean Construction teori om slöserier för att identifiera och kategorisera problemområden i dessa flöden. För att sedan hitta grundorsaken till dessa problem gjordes en rotorsaksanalys. Rotorsaksanalysen visade på att grundproblemet i nästan samtliga fall går att härleda till antingen brister inom planering eller kommunikation. Genom att tillämpa Last Planner System teoretiskt på grundproblemen kan en tänkbar lösning föreslås. Ur ett teoretiskt perspektiv kan en implementation av LPS eliminera problem med inleverans, materialhantering och lager av material enligt denna studie.

    För att lyckas med implementeringen är det viktigt att tänka på följande saker:

    1. Utbilda personal inom verktyget

    2. Ledarskapets stora betydelse

    3. Sluta inte att utbilda och utveckla personalen

    4. Lös konflikter direkt och låt inte dem ligga under ytan och förstöra samarbetet

    Ett digitalt kommunikationsverktyg hade sannolikt ökat integration och samarbete mellan parter. Fortsatt forskning krävs för att utvärdera den teoretiska lösningen genom att utföra fälttester med Last Planner System.

    Omvårdnadspersonalens erfarenheter av handledning från arbetsterapeuter inom gruppboende2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The aim of this study was to describe healthcare workers experience of supervision from occupational therapists within group homes for adult people with neurodevelopmental disorders and/or intellectual disabilities. Methods: The study is based on a qualitative method with semi-structured interviews to examine the participants experience. Ten participants from six municipalities from different parts of Sweden participated in the study. When processing the collected material, a qualitative content analysis was used where the material was transcribed, condensed, coded and categorized. Results: The analysis of the interview material resulted in three categories; the structure of the supervision, the needs and availability of the occupational therapist and the importance of supervision. The results of the study show that the supervision contributed to the feeling of safety for the healthcare workers in the performance of occupational therapy interventions and constituted a valuable occasion for new ideas and viewpoints to be developed. In case of insufficient supervision and second-hand information, the healthcare workers experienced an uncertainty in the performance of occupational therapy interventions. The result also showed that the participants wanted the occupational therapist to be more perceptive to the healthcare workers opinions and experiences. Conclusion: The study has contributed to increased insight into the healthcare workers experience of occupational therapy supervision and areas within supervision that should be developed.
