    The effect of blockchain related corporate name changes on stock prices: An investigation into the creation of cumulative abnormal returns following a blockchain related corporate name change2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Investments in cryptocurrencies have generated extraordinary returns and the interest in cryptocurrencies and blockchain technology from the public, companies, investors, and news media has increased substantially in the past years. This has led certain corporations to change the strategic direction towards blockchain technology, as well as changing the corporate name to reflect an association and these name changes has created substantial increases in the price of that stock. Existing literature of corporate name changes has touched upon several aspects of the subject. However, no specific research connected to blockchain and cryptocurrencies has been conducted. The purpose of this research is therefore to investigate the effect of corporate name changes related to the terms blockchain or cryptocurrency on the price of stocks. A standard event study methodology was applied to determine if the name change creates abnormal returns. The method used has a quantitative approach to the research and relies on statistical testing of numerical data to reach a conclusion. An investigation of 11 firms was conducted to examine this topic. However, there were no firms that had included the term cryptocurrency in the corporate name. The findings from this research reveal positive and significant cumulative abnormal returns on the announcement date of a blockchain related corporate name change. Furthermore, over the full event window, a significant and positive cumulative abnormal return was observed. Thus, it can be concluded that name changes related to blockchain has a positive effect on the stock price and today's investors seem to perceive a corporate name change within the context of blockchain as positive.

    Barn och vårdnadshavares minnen av deltagande i pedagogisk dokumentation2018In: Tidsskrift For Nordisk Barnehageforskning, ISSN 1890-9167, Vol. 17, no 8Article in journal (Refereed)
    Abstract [en]

    The purpose of the article is to contribute with knowledge of pedagogical documentation with a particular focus on the importance of documentation from a democracy perspective. While there are many studies of pedagogical documentation, few studies explicit examine this practice from the perspective of children and guardians. Analyses, based on focus group data of children ́s and guardian ́s conversations from memories of the children ́s time spent in preschool in relation to educational documentation work, are presented. Pedagogical documentation practice is shown to contribute to the creation of a community of practice at the preschool, which in turn enabled democratic education.

    Det vidgade textbegreppet: Med fokus på spelfilm i undervisningen och elevers identitetsskapande2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Film används ofta för att fylla ut undervisningstid utan ett egentligt syfte och flertalet elever upplever film som en form av belöning som sker vid särskilda tillfällen utan bearbetning. Syftet med litteraturstudien är att klargöra spelfilmens ställning i grundskolan och hur spelfilm används som pedagogiskt verktyg för elevers identitetsskapande i skolan. Detta kommer besvaras genom följande frågeställningar:

    • Är spelfilm användbar i svenskundervisningen?
    • Hur kan undervisning med spelfilm i svenskämnet utformas för att stötta elever i deras identitetsutveckling?

     

    Den litteratur som ligger till grund för studien består av tidskriftsartiklar, doktorsavhandlingar och licentiatuppsatser. Dessa i sin tur är skrivna av nationella och internationella forskare. Resultatet visar att det finns olika uppfattningar om spelfilmens värde. Till följd av att spelfilm inte undervisas i samma utsträckning som typografisk text har det skapats en hierarki där typografisk text värderas högre än spelfilm. I resultatet framgår det hur spelfilm kan undervisas samt mediets koppling till elevers identitetsutveckling.

     

    Texten är skriven ur ett lärarperspektiv med målet att sprida kunskap och inspirera yrkesaktiva lärare. Med vår studie vill vi att lärare ska bli medvetna om spelfilmens användbarhet genom att ta del av den forskning vi sammanställer.

    Last Night in Sweden: A Critical Discourse Analysis of the Image of Sweden in International Media2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This is a study of how the image of Sweden is constructed in international media. Using the country as a swinging bat in debates on socialism and progressiveness is nothing new but has had an upswing during recent years as a result of the global rise of right-wing forces. With the help of Critical Discourse Analysis, four articles from the United States and the United Kingdom are analysed. These are then presented according to Fairclough’s three-layered model. With the help of previous research on Sweden in international media, fake news and nation branding, these findings are then explained and put into context.The study finds that the image of Sweden presented in media tends to follow the narrative of Good Sweden and Bad Sweden. On the one hand is the classic welfare state in the north, which takes care of its people and with high levels of trust between the actors. On the other hand is a country in ruins as a result of letting in too many immigrants. Both narratives rely heavily on stereotypes. The discussion tends to use Sweden as an example, when it is really about ideologies and values. Another result shown by the study is that fake news is a common trace in news about Sweden, not only in alternative media but also in the established elite media. This can be seen as a result of the hardening situation in the media business as well as the rise of right-wing forces.

    Det dolda ansiktet: En studie av kvinnans roll i IS tidskrifter Dabiq och Rumiyah2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna studie är att undersöka hur kvinnans roll framställs inom Islamiska statens tidskrifter, Dabiq och Rumiyah. Studien är grundad på en textanalytisk undersökningsmetod med IS texter i fokus.  

    Frågeställningarna som berörts i denna studie är följande:   

    Hur framställs kvinnans roll inom IS?  Vilka argument använder IS?  Vilka källor refererar IS till? 

    I studiens analys framkommer en ambivalent syn på kvinnans roll, det vill säga även om IS avvisar kvinnor från att delta i strid medger de att kvinnorna är grunden till deras stora framgång i jihad. Männen inom IS styr vad som är gångbart sensationellt i kvinnans roller vilket resulterar i ett patriarkaliskt maktperspektiv som cementerar hur kvinnor och män ska vara. Kvinnans roller utökar IS globala utsträckning med hjälp av producering, propaganda samt rekrytering för att stärka IS nätverk av kvinnor och medverkar till IS överlevnad.

    Från misstanke till diagnos - effektivare utredningsprocess för patienter med demenssjukdom.: Ett förbättringsarbete i primärvården.2018Independent thesis Advanced level (degree of Master (Two Years)), 80 credits / 120 HE creditsStudent thesis
    Abstract [en]

     

    Background Dementia is not curable, although provided adequate examination one can relive symptoms and improve the quality of life of patients. However, the excessive time taken for basic assessment in Swedish primary care today is causing distress for the patient and their kin.

    Purpose The overall purpose of this improvement project was to enable earlier care for dementia patients, thus improving their quality of life. The specific purpose was to enable diagnosis or completed assessment within 12 weeks. The project also analysed the experience of staff during the project, as well as the experience of the patients’ relatives throughout the assessment process.

    Method A PDSA cycle was implemented when adjusting working methods related to booking of appointments with physicians. Semi-structured focus group interviews were also used.    

    Results The number of cases completed within 12 weeks increased from 62% to 93% and 61% to 95% at the two health centers respectively. Staff saw improved collaboration between teams and units as a key success factor. Patients’ relatives experienced the assessment process as smooth, and that shorter process times led to improved quality of life for the patient and their kin.

    Habiliteringsplanering - begripligt, hanterbart och meningsfullt: Förbättringsarbete för att öka familjernas delaktighet i habiliteringsplanering2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background: The work process of Habilitation planning embraces several central aspects in healthcare today, such as person centered care, participation, shared decision-making, co-production and individual planning. The work process represents a view that combines the patient’s knowledge and experience with the clinician’s professional knowledge, to create good care. 

     

    Aim: An improvement project was conducted at a habilitation center, aiming to increase families’ perceived participation in Habilitation planning. The aim of the study was to explore the co-workers’ experiences of Habilitation planning.

     

    Method: A local improvement project was conducted based on the Improvement model. A case study with focus group interviews and a qualitative content analysis was performed. The analysis was connected to espoused theory and theory-in-use.

     

    Result: All nine parents asked, perceived themselves as involved and the percentage of Habilitation planning judged as being of good quality increased from 14 to 19%. The study results showed great gaps between espoused theory and theory-in-use, e.g. for team work.

     

    Conclusion: To make Habilitation planning a work process really adding value to the patients, the gap between espoused theory and theory-in-use needs to decrease. Addressing this with improvement knowledge requires useful measurements.

    Användbar och tillgänglig webbkatalog för habiliteringens kursutbud: Ett förbättringsarbete för tillgänglig webbkatalog och en studie av vilka faktorer som har betydelse för hur den används2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background

    Knowledge about one's current disability and its consequences makes everyday life easier. The habilitation center offers approximately fifty courses each semester. The program was recently digitized which decreased costs and administration time and expected to increase accessibility and user-friendliness. Target groups and staff experienced the opposite.

    Purpose

    The QI-project aimed to improve the availability to the courses by making the e-catalogue more accessible and user-friendly.

    This study aimed to describe the staff's perception of the factors affecting the functioning of the e-catalogue at a micro, meso and macro level. The study was delimited to include the business perspective.

    Method

    The improvement ramp and the model of improvement. Focus interviews was analyzed with qualitative content analysis and linked to micro, meso and macro level with The Clinical Adoption Framework (CAF) as a theoretical reference frame.

    Results

    The QI-project didn't meet its objectives in full. The content analysis identified six factors at micro and meso level.

    Conclusions 

    For a digital tool to be perceived as useful, knowledge about the organization and its processes at a micro level is required, so that the right conditions and support can be given at a meso level.

    A STUDY OF NATIONAL BIM GUIDELINES FROM AROUND THE WORLD DETERMINING WHAT FUTURE SWEDISH NATIONAL BIM GUIDELINES OUGHT TO CONTAIN2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The purpose of this study was to increase the efficiency of the planning stages in the building industry. The goal was to produce valuable information that will be useful in the future development of Swedish national BIM guidelines.

    Method: The study has been conducted by following the principles of content analysis. “Content analysis is a research method that uses a set of procedures to make valid inferences from text”. By searching for and analysing the content of national BIM guidelines, valuable information for future development of Swedish national BIM guidelines would be produced. The BIM guidelines had to fulfil two criteria in order to qualify for the study:

    1. Be a national BIM guideline.
    2. Have a version in English.

    Once selected, the guidelines were analysed using 11 topics, namely BIM execution plan, Level of Development, Format standards and their application – interoperability, accountability, filing, archiving, modes of collaboration, operations and maintenance, simulations, pre-qualifications, BIM functions through project phases. These were chosen based on works by R. Sacks, Gurevich, & Shrestha and Hooper.

    Findings: Out of the 81 BIM guidelines listed in the BIM guides project by BuildingSMART, 10 national BIM guidelines from 10 different countries were chosen for further study. NATSPEC from Australia, Belgian guide for the construction industry, CanBIM from Canada, COBIM from Finland, HKIBIM BIM project specification from Hong Kong, New Zealand BIM handbook, Statsbygg BIM manual from Norway, Singapore BIM guide, Level 2 PAS from the UK and NBIMS from the USA.

    All topics have a high level of inclusion, pointing to that the topics from Hooper and Sacks are relevant on a global scale. Pre-qualifications scored the lowest, and BIM functions through project phases scored the highest.

    Implications: Cover all 11 topics reviewed in this study. Avoid strict protocols with excessive level of detail, but rather formulate guidelines as frameworks, thus making them user-friendly and usable. Formulate guidelines so details may easily and logically be worked out in a BIM execution plan. Make a plan to keep the documents up to date.

    Limitations: This study only includes national BIM guidelines with English versions available. It has solely been conducted by document analysis and does therefore not provide much information on what current users of national BIM guidelines think of the guidelines reviewed, apart from what is mentioned from Hooper’s work. The score of each guideline indicate how much information it contains, and a high score may therefore not necessarily indicate it is the most user-friendly and readable guideline.

    Keywords: BIM guidelines, national BIM guidelines, BIM implementation

    BIM inom offentlig fastighetsförvaltning: Hur relevant information kan tillhandahållas med BIM2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The shortcomings of information transfer between the different building phases has a negative impact on facility management (FM). Because of the complex information needs it is important that the FM specifies which information they want delivered from the design and construction phases. The negative impact can be reduced with BIM because of its ability to ease communication between the disciplines. Therefore, the aim of the thesis is to ease the implementation of BIM within the technical FM of the public sector, and following questions are asked: (1) What does the process of operation and maintenance in a technical department of FM in a public sector look like? (2) Which information is needed in this process, to effectively accomplish the FM activities? (3) How can you, with BIM, provide this information? (4) How should you do to succeed with the implementation of BIM in FM? 

    Method: The approach of the thesis is a case study, studying the technical department of a public FM. All questions are based on each other, which means that the data collection and the analysis have been done in interaction. Mostly, the questions have been answered by literature studies and interviews, but observations and document analysis has also been done. 

    Findings: The result of the first question shows that the process of operation and maintenance is complex and includes many different disciplines. The process includes an administrative part where actions and intervals are connected to the installations in the FM system. The process also includes that the maintenance personnel performs the actions, and if problems occur, the technical manager and the operating engineer are being consulted for a solution. 

    The result of question 2 shows a big need of different information. The information needed by the most people are; placement, the installation’s component and manufacturer/supplier. Although some information might not be needed by a lot of people, it is important to point out that the information does not have lower value. 

    The result of the third question shows that the information that emerged from question 2 could be provided with BIM by connecting the information to an object through property sets, databases or portals. 

    The result of the fourth question shows the way to implement BIM in FM; process mapping, information analysis and connect the information. 

    Implications: The study shows that there are good opportunities to use BIM to provide relevant information needed by the FM. It is important to analyse the processes and information needs within the organisation. The implementation should be done in connection to a new construction or a reconstruction. 

    Limitations: The study only observes operation and maintenance within the technical department of FM and does not investigate either economical nor technical aspects. The result is considered to be generally valid, however, a more complete result can be achieved with a bigger research of the FM organisation and several interview respondents.

    Organisatoriskt lärande för att öka vårdkvalitet: Lärdomar av att utveckla processledning vid en operations- och intensivvårdsklinik2018Independent thesis Advanced level (degree of Master (Two Years)), 80 credits / 120 HE creditsStudent thesis
    Abstract [en]

    Background: Complex organizations need to be patient centred, focus on processes, have holistic view and promote organizational learning to secure quality. Operation and intensive care unit, Ryhov, has potential to develop its Process Management (PM) and there is room for improved patient participation.

     

    Purpose: The purpose of the quality improvement project (QIP) was to identify and reduce quality gaps affecting patients, by develop PM and organizational learning. The purpose of the study was to describe co-workers’ understanding of the connection between PM and quality of care and describe their experiences from QIP.

     

    Methods: The QIP has developed organizational learning concerning two pilot processes by using Nolan’s model for improvement. The study of the QIP is qualitative, based on six focus group interviews. Qualitative content analysis was used to analyse the interviews.

     

    Results: PM demands access to improvement and professional knowledge. The organization need to create conditions for sustainability, make benefits obvious and ensure enough resources. Quality of care increases when the organization works structured and patient centred.

     

    Conclusions: PM creates conditions for continual improvements with focus on organizational learning and increased quality of care. The organization need to actively make PM an integral and living part.

    Förbättrad informationsöverföring i äldreomsorg: - en fallstudie om implementering av ett modifierat SBAR-verktyg2018Independent thesis Advanced level (degree of Master (Two Years)), 80 credits / 120 HE creditsStudent thesis
    Abstract [en]

    Lack of communication is the single biggest reason for errors in healthcare. By standardizing the communication, the variation is reduced and logic and mutual agreement are created. The purpose of the improvement work was to increase patient safety by simplifying communication by introducing the SBAR communication tool. The subsequent study aimed to investigate how SBAR was experienced in the elderly care team, and to describe success factors and difficulties at the time of implementation.

     

    The author was inspired by action research. A content analysis has been applied on the data collected.

     

    There was an improvement in the information transfer, but the unit did not reach the set targets. SBAR was found useful by the professionals after practical training. The professionals felt greater security with a combination of oral and written report. The project created common learning through participatory observations and by clarifying the surrounding structures for the professionals. The project contributed to changed focus from an individual to a system level concerning the information process. The SBAR structure was slightly simplified to fit the multilingual context. New areas for improvement were identified and an activity board for the elderly was created. Keeping consistent education and training temporary staff was a challenge.

    Näringsriktiga mellanmål och tätare viktkontroller minskade ofrivilligviktnedgång: En kvalitativ studie om ett förbättringsarbete på ett äldreboende2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Det finns omfattande belägg om nutritionens betydelse för äldres hälsa och livskvalitet. För äldre patienter som bor på äldreboenden förekommer undernäring och ofrivillig viktnedgång vilket kan leda till ökade komplikationer såsom fall, trycksår och dödlighet.Syfte: Syftet i denna uppsats består av två delar. Syfte i det genomförda förbättringsarbetet: Att alla patienter på Solgården erbjuds bästa möjliga förutsättningar för att inta en god och näringsriktig kost. På lång sikt är målet att alla patienter ska ha ett gott nutritionsstatus. Syftet med studien av förbättringsarbetet: var att beskriva om och i så fall på vilket sätt personalen upplevde att förbättringsarbetet resulterade i förbättringar (i vården) för personer med demenssjukdom samt beskriva hur personalens erfarenheter av förbättringsarbetet kan bidra till förbättrad nutritionsvård för personer med demenssjukdom.Metod: Förbättringsarbetet genomfördes utifrån Nelson, Batalden och Godfreys (2011) Improvement ramp. I studien användes fallstudie med kvalitativ, induktiv metod och datainsamlingen bestod av intervjuer.Resultat: Förbättringsarbetets resultat visade att andelen mellanmål som innehöll tillräckligt mycket kalorier ökade och att journalförda viktuppföljningar gjordes i högre utsträckning.

    Effektivare resursanvändning vid återbesök inom psykiatrisk öppenvård: Utveckling, test och erfarenheter av digitala vårdmöten2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund

    Hög andel sena återbud och uteblivna besök, är ett problem vid psykiatriska kliniker och orsakar effektivitetsbrister då tillgängliga resurser inte används optimalt. Fysiska besök och telefonkontakter behöver kompletteras med fler mötesformer för att bättre möta patientens behov och öka tillgängligheten.

    Syfte

    Syfte och övergripande mål med förbättringsarbetet var att öka tillgängligheten till psykiatrisk öppenvård genom att erbjuda digitala vårdmöten. Syftet med studien av förbättringsarbetet var att identifiera erfarenheter från förbättringsarbetet som kan användas som lärdomar i fortsatt verksamhetsutveckling.

    Metod

    Nolans förbättringsmodell har används i förbättringsarbetet. Studien är en fallstudie, inspirerad av interaktiv ansats med kvalitativ metod.

    Resultat

    Genom utveckling och genomförande av 20 digitala vårdmöten är lärdomarna att digitala vårdmöten är ett komplement till besök på mottagning och att digital teknik stödjer arbetsprocessen. Studiens resultat visar att ledningen, strukturer och medarbetares delaktighet är centrala vid kvalitetsförbättringar.

    Slutsatser

    Inställning till patientens kapacitet och digital teknik är central för att erbjuda mötesformen. Tekniska lösningar måste vara lättillgängliga. För att dela kunskap, öka tryggheten i det nya sättet att mötas och undanröja hinder som uppstår är arbetsmöten viktiga. Ledningen utgör en central roll för att påverka förbättringskulturen och de värderingar och mönster som finns i verksamheten.

    Improvement of material supply systems: A case study in a Swedish pharmaceutical company executed on a research and development plant2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Material supply systems have for a long time been regarded as an important function with strong potential to increase the performance of companies in different industries. Consequently, substantial research has been conducted in the field. However, in the pharmaceutical industry within research and development plants, material supply systems have historically not been a prioritized function. Therefore, there is a research gap regarding material supply systems in that peculiar context. This study aims to fill that gap by investigating how a material supply system could be designed and which factors are critical to achieve a cost-efficient service level within a research and development plant in the pharmaceutical industry. To do so, a single case study has been conducted at a Swedish pharmaceutical company’s research and development plant. An abductive approach has been applied to both test if the general design principles developed in other industries and business functions can be applied to this context. Further, context specific factors affecting the material supply system design needed to be identified and investigated to adapt the general design principles to the specific context by generalizing data. The empirical data was collected by utilizing focus groups, interviews, observations and documents. The findings yielded that there is a substantial potential for improvement of material supply systems within the context of this study. The existing decentralized inventory structure at the case company was a particularly vital aspect that hindered the system from operating cost-efficiently in relation to the service level and a centralization is crucial to improve. Further, calibration and a general decrease of safety stocks, order points and order quantities is essential to uphold a consistent service level at a justifiable cost at the case company. The general design principles and formulas retrieved from the theoretical framework was partly applicable in the context of this study but needed some adjustments. Especially the low volume articles with high variety in consumption rate was not suitable to be managed by the existing methods and needed another approach. Further, the context establishes high requirements on system dynamics, it comes with boundaries due to laws regulating the industry, and companies in the context generally need to be better at aligning their design factors to the purpose. The result of this study adds valuable content to the research field and fills the gap for material supply systems in the context of research and development plants in the pharmaceutical industry. Further studies are needed in this field to investigate how articles with low and varying demands can be managed within material supply systems cost-efficiently and with high service levels.

    Comparison of security level and current consumption of security implementations for MQTT2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    IoT is a rapidly growing area with products in the consumer, commercial and industrial market. Collecting data with multiple small and often battery-powered devices sets new challenges for both security and communication. There has been a distinct lack of a IoT specific communication protocols. The industry has had to use bulky interfaces not suitable for resource-constrained devices. MQTT is a standardised communication protocol made for the IoT industry. MQTT does however not have built-in security and it is up to the developers to implement a suitable security countermeasure. To evaluate how different security countermeasures impact MQTT in complexity, current consumption and security the following research questions are answered.

    How do you derive a measurement from the SEF that can be compared with a current consumption measurement?

    Which level of security, according to the SEF, will RSA, AES and TLS provide to MQTT when publishing a message to a broker?

    What level of complexity is added to MQTT when using chosen security countermeasure?

    Which of the analysed security countermeasure upholds an adequate security level while also having a low current consumption?

    To answer the above research questions an experiment approach has been used. Implementations of TLS, RSA and AES have been evaluated to measure how they affect the security level and current consumption of an MQTT publication, compared to no security countermeasures at all.Both RSA and AES had the same security level, but the current consumption for RSA was four times higher. The experiment showed that the security level is significantly higher for TLS, while it also has the highest current consumption. The security countermeasure evaluated differs greatly. TLS provides complete protections, while RSA and AES lacks authentication and does not ensure integrity and non-repudiation.Even if the current consumption for TLS is higher, the security it provides make it unreasonable to recommend any of the other security countermeasure implementations.

    1. Which parameters can affect the rendering of the user interface on a mobile application?

     

    1.  How does the rendering of the user interface differ from web application, hybrid application and native application?

    Method – The study uses a literature study to answer the first research question and uses an experimental study in which a hypothesis and prediction are formulated and tested to answer the second research question.

     

    Results – The result of the study shows that the performance of the native application’s user interface does not always perform better when performing the same task as the corresponding web and hybrid application. The web application in general had the best performance in the user interface, while hybrid application often performed inferior to the corresponding application types.

     

    Implications – The study contributes to extend the knowledge of native application’s, hybrid application’s and web application’s performance in the user interface, and can give companies and developers reference data to base their decision on the choice of application type. The study shows that all application types are worth considering, but the web and native application performed slightly better.

     

    Limitations – No long-term tests could be compared because ADB does not read graphical data for web applications and Chrome DevTools cannot perform long running tests.

    Instagrams filter - Jakten efter den perfekta bilden: En studie om hur redigering av en bild kan påverka attityd till ett motiv.2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose – The purpose of the thesis is to investigate whether there is any editing combination in the form of different filters published in the Instagram app, which is noticeably different from each other in the form of negative or positive response.

    Method – In order to obtain answers to the question, the study has sought to anchor as many theories as possible in scientific, published material.

    The method of ”small-N-study” in this study will be applied when collecting information about the different filters that the Instagram app allows the user to choose from.

    A quantitative survey is conducted in an attempt to obtain statistics on how the filters can be ranked from most popular to least popular. To further validate the answers to the questionnaire and to answer the questions 1.1 and 1.2 in the thesis, three interviews are conducted. The aim is to achieve more qualitative answers to the questions and then to compare and analyze the results of the survey.

    Findings – This study has found that a combination of: moderately colorful, normal contrast, medium opacity, neutral color tone, blue color and medium brightness are good variables to create good a filter. Highly matte and colorless colors, very low contrast, black and white (neutral colors), cool color tones, high brightness and high opacity of the filter are qualities for a filter that gets a lot of negative response.

    The most popular filter of all 23 in the Instagram app is Clarendon, while the filter with the most negative response is Hefe.

    Implications – A risk of working deductively may be that theories that already exist on the subject and from which the researcher assumes will target the results of the study.

    When conducting a ”small-N-study” there is a risk that the variables being analyzed are too few to answer the question at issue. 

    When conducting a survey, there is always the risk that the questions are too leading, that the test person does not understand, misinterprets or fails to engage in the subject to answer the questionnaire truthfully. When conducting an interview, there is a risk that the interviewees are insufficiently aware of the issues that they can not answer in detail or honestly on the questions. 

    Limitations – The study is limited to the resources available in time. The subjects who participated in interviews and questionnaires are limited to those the writer could reach out to. Just like the theory found on the subject is limited by the ability of the author to search and review information, as well as language skills and the data published in library and database. The results of the study are limited to the funds used for the objects examined.

    Exploring design content in cad-models and knowledge bases using graph theory and filtering2017In: Machine Dynamics Research, ISSN 2080-9948, Vol. 41, no 4, p. 5-15Article in journal (Refereed)
    Abstract [en]

    This paper focus on what types of relations exist within CAD-models and in KBE-systems connected to them. It describes how engineering knowledge stored in CAD-models and KBEsystems can be analysed through the application of graph theory, visualization and filtering. The paper is organised as follows: First the information models for CAD-models and KBEsystems are introduced and graph theory in connection with these information models is presented. The theory is then applied to a real case which is a CAD-model that was automated using a commercial KBE-system where the number of rules made it hard to engineers to grasp the model. By applying the concepts presented in this paper it was possible to identify critical design parameters and to inspect the logical model of the product.

    Industrial policy: Political considerations, payoffs, and peculiar incentives2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis consists of four independent papers. They deal with some aspects of industrial policy, namely public supports to firms that are intended to support innovation and growth at the firm level, using Swedish data. Two papers study the efficiency of current Swedish policies by estimating the effects of subsidies and public loans to firms, respectively.

    The results on subsidized firms suggests that there are some positive effects on profits and productivity, but these diminish and disappear over time. The results of public loans are more positive with long lasting effects on productivity and sales but only for smaller firms. Public loans do not lead to an increase in the number of employees in the firms that receive them.

    The third paper studies the selection of firms for subsidies and the incentives firms have to seek them. By modeling the decision to seek subsidies as a trade off between producing in the market and seeking grants, the results suggest that firms with low market productivity might self-select into seeking grants. The empirical results are in line with the theoretical predictions.

    The final paper studies the incentives that politicians have to implement programs and policies that they know will be inefficient. Since a lack of political action can make the politicians look incompetent, incumbentens have incentives to implement policies even though they know that these will be ineffective, to signal competence towards the voters.

    Employment, Competition and Firm Performance: A Sub-Saharan Africa Perspective2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis addresses employment, competition and firm performance with a focus on Sub-Saharan Africa. The thesis consists of three individual papers and an introductory chapter. The purpose of each paper is to analyze firm performance. The main region of interest is Sub-Saharan Africa where countries in this part of the world are at lower levels of economic development and have experienced economic transition and strong firm investments. The papers contribute to existing industrial organization research by studying the effects of competition on R&D, effects of firm performance on innovation, and the determinants of informal employment and monthly wage earnings.

    The first paper focuses on firm performance which is found to affect firm innovation positively. This suggests that a firm’s decision regarding the scope of its total sales impacts its innovation capabilities. The second paper investigates the relationship between competition, R&D expenditure and innovation. It is found that a firm’s research efforts increase with an increase in levels of competition but at a diminishing rate confirming a non-linear, inverted-U relationship between competition and research expenditures. The third paper analyzes what determines informal employment and monthly wage earnings in formal firms. The results show that marginal benefit of higher education is lower for informal employees and that returns on education are much higher for workers with higher education.

    Firm Performance And Innovation In The Developing Countries: Evidence From Firm-Level Survey2017In: Corporate Ownership & Control, ISSN 1727-9232, E-ISSN 1810-3057, Vol. 15, no 1, p. 235-245Article in journal (Refereed)
    Abstract [en]

    This paper investigates the relationship between firm performance and innovation in developing countries using micro data from enterprise surveys. The purpose is to empirically test the importance of firm performance in terms of sales, for a firm’s proneness to innovate specifically in developing countries. A two-stage least squares (2SLS) model is applied to a sample of 2356 firms from the manufacturing and service sectors. Results show that firm performance, defined as sales, is found to be a significant factor contributing to innovation among firms. This relationship holds in manufacturing firms even when distinguished from the services sector. The findings underline the importance of firms’ performance through increased sales. The paper adds to the existing limited research literature on performance and innovation studies in developing countries especially Africa. The paper results differ from previous research studies where focus has been on innovation impact towards performance. As a policy option, developing countries need to improve and promote an increase in firms’ sales that would spur them to introduce a new or substantially improved product or process.

    Abstract [en]

    Attacks on academic freedom in Turkey have become increasingly systematic in recent years and thousands of academics have been dismissed. This study reflects on the effects of this worsening repression through interviews with academics in the social sciences, both those dismissed and those still active in their profession. Although the dismissed academics are socially in a very precarious position, they are continuing their scholarly activities in alternative, underground forms. This resistance stands in contrast to the accommodation and self-censorship that seem, according to the interviewees, to prevail in university departments.

    En analys kring förbättringsmöjligheter av exteriör utformning på volymhus2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: Industrial built modular housing is an off-site construction type, which means the modules are built in a factory and transported to the building site for assembly. The modules are built on an assembly line in a standardized and rationalized process. The modular building system has potential to lower the housing shortage, since it is more time and cost effective compared to traditional construction types. The disadvantage with the modular housing industry is that you often see poor exterior design results, due to the lack of flexibility in the system. Facades can be repetitive and have too large proportions. Therefore, the purpose of the work is to get an understanding of how the quality of exterior design can be improved in modular housing, by answering (1) How is the correlation between exterior design and modular building described by architects in the industry? (2) What are the restrictions for exterior design in modular housing? (3) How can the quality of exterior design in modular housing be developed, in regards to the restrictions of the building system?

    Method: A literary study is performed to identify the main restrictions and also the possibilities of development for modular housing. Combined with the literary study, interviews are being held with six respondents from the industry. The respondents explain their view on the correlation between exterior design and the modular building system. The interviews are also studying different buildings where the respondents have been involved.

    Findings: The technical restrictions are mainly the size of the modules due to transporting requirements and the joints between them. The ability to adjust to them are limited by the budget of the project. The projects tend to be more cost-oriented, rather than focusing on architectural quality and therefore the exterior design is suffering. To create good modular houses that give something back to the city, there must be a change in the industry. Contractors and the municipalities are the most important participants in this process.

    Implications: The biggest improvement possibilities that can make the most change in the future are; competition on the market, ambitious contractors, process and product development, higher municipal requirements and also new technical solutions that provide good design to a lower price. 

    Limitations: The result is limited to only exterior design in the modular housing industry, focusing on multi-family housing on the Swedish market. The study is a general analysis and does not go into depth on each problem. It is more meant to be a guideline to where the problem areas exist.

    Arbetsberedning i produktion: Kommunikation och informationsöverföring mellan produktionsledning och yrkesarbetare inom organisationen Peab Sverige AB2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Abstract

    Purpose: The construction industry's productivity in Sweden is low and one of the major causes of this is the lack of work preparation. A study showed that 45 percent of the fault causes could be linked to work preparation and accounted for up to 30 percent of the error costs. Work preparation is a tool for efficient and safe execution of work, but despite good foundation, the use of it does not work at present. The lack of use of work preparation is to a large extent a result of poor communication and information exchange between production management and occupational workers in production.

    The aim of the work is to investigate communication and information exchange between production management and occupational workers in the production. Identifying deficiencies in communication and information exchange, how they can be rectified. As well as provide improvement suggestions for the use of work preparation as a tool between production management and occupational workers.

    Method: To achieve the goal, a qualitative case study on three building projects has been carried out. The methodology has been semi structured interviews with team members involved in the work preparation, observation of meetings, document analysis of the organization's work preparation and a literature study to gain knowledge of the factors that cause deficiencies in communication and information exchange of the team members involved in the work preparation.

    Findings: The identified underlying causes of communication and information exchange failures are too little information about work preparation, unclear how to implement it and too few tools. Production management does not realize the value of work preparation, which means that the time required for a good work preparation is not set aside.

    Implications: An adequate work preparation is an important factor in increasing the productivity of construction projects. In order to achieve an adequate workforce the organization must have stronger guidelines and more tools to streamline it and appoint the responsible party to implement them. Production management needs to realize the value of a work preparation and set aside the time required for it to be beneficial.

    Limitations: The limitations on the work have been a requirement based on the time perspective of the work. The work is considered despite the limitation to Peabs office in Jönköping applicable to other projects. The work has not had the purpose of changing the work preparation but focuses on the use of it, how it is worked and used. Reflecting that work preparation is a general term not only used in the construction industry, the result is generalizable to not only building projects but in all areas of work that require a comprehensive work preparation in an efficient and flexible manner.

    "Jag tycker att det är läroplanens fel att bedömning har en negativ klang": En kvalitativ studie om förskollärares uppfattning om bedömning i förskolan2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Studiens syfte är att bidra med kunskap och insikt om hur förskollärare uppfattar begreppet bedömning och dess innebörd i förskolan. Studien utgår från fem semistrukturerade kvalitativa intervjuer med förskollärare och dess teoretiska utgångspunkt är fenomenologin. Resultatet visar att förskollärarna i studien uppfattar att bedömning av barn är något som sker i förskolan trots medvetenheten om att det går emot läroplanens intention. Vidare framgår att bedömning kan ge både positiva och negativa konsekvenser för såväl barn som verksamhet men beror på den enskilde förskollärarens förståelse och fokus vid en bedömning. Resultatet visar att bedömning i förskolan är nödvändigt då den kan främja barns lärande och utveckling. Dock framgår det att förskolans läroplan behöver en reglering där det tydliggörs gällande bedömning, om vad som ska bedömas eller inte, eftersom det uppenbart finns olika synsätt och förståelser. I resultatet är en osäkerhet synlig hos förskollärarna där det till stor del handlar om att bedömning har en negativ klang och anses motsägelsefull gentemot läroplanen, vilket skapar osäkerhet och att begreppet därför undviks.

    Improving material flow and production layout using Value Stream Mapping: A case study in a manufacturing company2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The movement and handling of material are necessary activities, however, commonly regarded as waste. Moving and handling material more times and over longer distance than necessary is time consuming, costly and unproductive. Therefore, a suitable material handling (MH) system with appropriate facility layout is advocated. The purpose of this thesis is to explore options for material flow improvements and handling of material in production area. This comprises of a study of the material flow from storage to production areas and the handling of material in production section A. If necessary for improvements of material flow, a change in layout design will be recommended. The research approach for this thesis is a case study where data has been collected from documents, observations and interviews. The study shows that 9 % of the production time of one article is spent on manual material handling (MMH). These activities are classified as both waste and necessary, however not adding any value. The same applies for the material flow. Unnecessary distances of movements are caused by the current location of storage, operations and lack of proper structure for handling and moving material. The contribution of this study is a list of suggestions for improving the material flow and handling. Changes for improvements are, namely, availability of appropriate equipment, storing materials closer to the operations and investing in automation and vision systems with cameras of robots. The material flow and the way the material is handled can further beimproved by a change in the layout of the production area. Connecting and rearranging operations can shorter and ease the movement of material with ample space to handle the material.

    Competitive manufacturing in a high cost environment2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background: The movement of production to low cost countries has been a prominent trend during recent decades. The offshoring trend has primarily been cost motivated and has had a negative impact on domestic economic growth. Manufacturing firms operating in a high cost environment must strive to develop core capabilities to enhance competitiveness. In this study, the focus is on operations capabilities and improvement areas in a specific context (i.e. high cost environment).

    Purpose: The purpose of the study is to evaluate critical operations capabilities and improvement areas for competitive manufacturing in a high cost environment.

    Method: The research process is based on the evaluation of an existing framework of operations capabilities in a high cost environment. The study adopts a multiple case study approach in which three Swedish manufacturing firms are evaluated. The data collection was conducted through a quantitative part (i.e. questionnaire) and a qualitative part (i.e. workshop discussion).

    Findings: The findings revealed that 16 operations capabilities and ten improvement areas were considered critical in a high cost environment. Four critical capabilities (i.e. total cost, productivity, conformance and customization flexibility) are more prominent and appear in all three cases. Two critical improvement areas, total cost and dependability, are more prominent and have a higher occurrence.

    Implications: The practical implication of the study provides firms with an overview and better understanding of critical operations capabilities and potential improvement areas in a high cost environment. The theoretical implication of the study is that firm characteristics (e.g. size and position in the supply chain) influence the importance of each capability.

    Designing an assembly line for modular house manufacturing: Increased efficiency of the manufacturing process2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Having an efficient production is vital for companies that are facing highly demanding customers along with tough competition. In addition, the production layout has a significant impact on the production efficiency hence it the choice of production layout is an important question to consider. A common production layout is the assembly line whereas companies with products that are not adequate for assembly line production; are seeing advantages of working with assembly lines. An example is the modular house manufacturing industry. Therefore, the purpose of the study was to investigate how an assembly line for modular house manufacturing and the related material supply may be designed in order to increase the overall efficiency of the manufacturing process. A single case study has been conducted at Zenergy AB, Skillingaryd. Empirical data has been collected through various sources; interviews, observations and document studies. In addition, a literature review has been conducted. The theoretical framework and empirical data has been established by the means of pattern matching and further on data analysis was done thus the results of the study were acquired. To conclude, it is shown in the results that implementation of an assembly line for modular house manufacturing can be beneficial despite the fact that its products are not adequate for assembly line production. Further on, there are three main critical factors to consider during the assembly line design process for modular house manufacturing. The critical factors are; line balancing, dry time and bulky materials. The critical factors will in turn have a significant impact on the choice of the assembly line production layout and the related material supply.

    Hantering av oanvänt byggmaterial på byggarbetsplatser2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The construction industry generates over 100 million ton of waste every year. When it comes to sustainability there is focus on material type, energy use, indoor climate, transports and waste. There are different certification systems that can be used to classify the buildings. In those certification systems there are no requirements on unused building material. 13 percent of the waste contains unused material. Unused material means material and products that are ordered to the construction site but is not used in the construction. The goal with the project is to analyse how to reduce the amount of unused material that goes to waste on big construction companies in Sweden.

    Method: This thesis is done through a qualitative study with the methods of literature study, document analysis and interviews. The literature study showed the current research front. Document analysis and interviews provided information about the companies sustainable goals, ethical regulations and working methods.

    Findings: The thesis shows that unused material occurs because of difficulties to quantify material because of the tight time schedule and not wanting to risk getting downtime in the production. The material gets damaged when it is handled on the construction site. The material is disposed to follow the ethical requirements of the company but is not in line with the sustainability goals. All interview responders agreed on the need of change to achieve the goal. The company has a working method where the trucks drive the material to a terminal and then out to the construction when it is time for the material to be used. This method could be used to minimize the disposal. Better communication between the projects would help unused material to be taken care of in a different project. The problem is that since it is different owners of the material depending on the purchase of contract it is not always easy to handle the material between the projects. To sell the unused material has been discussed before in the company but because of the lack of space and resource consumption it is problematic. Material also get damaged from the weather, but the lack of space is the reason why a tent not is a good solution.

    Implications: In order to reduce the occurrence of unused material, BIM, Lean, prefabrication and terminal management can be used. The materials that become unused can be taken care of in a different project, better communication between the projects will reduce material disposal.

    Limitations: The thesis is only theoretically analysing how to reduce disposal of unused material. No measures of time or economical aspects has been analysed. The work does not consider material like waste, consumables or material that are useable after demolishes. The result is useful in larger companies since smaller companies do not have the same problematics.

    Keywords: Building Information Modeling, BIM, disposal,  durability, environment, environmental objectives,  ethical rules, Lean Construction, material handling,  material waste, terminal management, unused building materials, waste and energy loss reduction.

    Abstract [en]

    This report describes the degree project by Oscar Gustavsson and Sulaymon Valizoda during the spring term 2018 at School of Engineering in Jönköping. The thesis has been carried out for Husqvarna AB in cooperation with Semcon AB as a final part of the authors’ education to engineers in Mechanical Engineering, Product development and Design. Within the company Husqvarna AB development and renewal are of great interest. In their development of grass collectors, this mission was assigned where the goal was to create new concepts and solutions to a grass collector belonging to one of Husqvarna AB's existing walk behind lawn mowers. The aim was to reduce the amount of spilled grass that lands on the ground and making it easier for the user to empty the collector after the grass has been collected. The work has been carried out as a concept study where a selected product development process has been implemented. The different phases and methods of the process from pilot studyto prototype are described to clarify how their approaches have been used. During the project a requirement specification was defined which specifically described what would be fulfilled and which could be followed as a basis in the development of concepts. To give this thesis a theoretical background, theories about the product development process, computer-aided design, vacuum forming, steel and welding joints has been applied.The study resulted in a final concept that were further developed and prototyped. The concept was considered by Husqvarna AB to be the best concept to proceed with.Testing and evaluation were performed on the prototype where the work was limited to. Further more, Husqvarna AB is able to continue the development and use the information from the work, which hopefully can be a helpin the development of a better grass collector.

    The role of instant messenger as computermediated communication tool for knowledge sharing and teamwork performance2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background: The virtuality of teams has increased due to the emergence computer-mediated communication (CMC) tools in the last decades. The push of instant messengers (IM) in private life has also lead to a stronger influx in the professional context. Theories such as media-synchronicity theory or the computer-mediated communication interaction model have described the capabilities of CMC tools and indicated their usage in teamwork related contexts. In this realm, the transmission of social cues has always been a potentially important matter of discussion.

    Purpose: Relating to studies from Asia and research conducted at the beginning of the century, the impact of the use of IM as communication tools on knowledge sharing and teamwork performance in Germany shall be assessed.

    Method: A partial least square-structural equation model is developed and tested using a survey distributed via a snowball approach among professionals in Germany.

    Conclusion: The results show that there is a significant positive relationship between the use of IM and knowledge sharing, respectively teamwork performance through its influence on communication quality. However, there is also a negative impact on interactivity which negatively affects knowledge sharing. It is also indicated that interruptions do not seem to have a negative impact on teamwork performance as it was discussed and rejected in several previous studies. Emoticons as a transmitter of social cues have not demonstrated to be of significant importance for communication in a professional context as of now. IM use leads to a positive impact on the perception of communication quality. Overall, IM are on the way to become an important communication channel in teamwork tasks, but will mostly serve as a complementary means of communication.

    How smart contracts can change the insurance industry: Benefits and challenges of using Blockchain technology2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The world is becoming more and more digitized. Recently many industries have started to research the blockchain technology and particularly smart contracts. One industry that so far has not adopted new technology in the same pace as other industries, is the insurance industry so this interview study aims at finding opportunities and challenges for insurance companies that want to learn about smart contracts and its use cases.By doing a literature review and performing interviews with blockchain experts and insurance company employees, this study found that both IT companies working with smart contracts and the insurance companies have limited knowledge of the legal aspect of smart contracts. The lack of standards and regulations allows IT companies to freely create smart contracts without much quality control. The insurance companies must innovate themselves in order to not be disrupted. The blockchain technology will offer many new insurance types and if the insurance industry fails to adopt the blockchain technology they may face market disruption.There is much room for future research following this study. It would be beneficial to research how contract theory could be used in practice during the creation of legally binding smart contracts. Furthermore, research around fraud prevention in smart contracts would be interesting as would an in-depth exploration of the ecosystem of third party software and services around smart contracts.

    Vem är mannen som slår?: En totalundersökning av alla fällande domar när det gäller grov kvinnofridskränkning under 2016.2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim in the following essay is to describe the characteristics of the man behind verdicts regarding interpersonal violence (IPV). Which explanations does he have for the violence he has used and how does his life circumstances look like? Furthermore, is there gender bias in the justice system: do the gender of the professionals in court affect the verdict or the size of the damages? 

    The essay is a quantitative study written with positivistic elements and from a perspective of gender order and legal sociology. To answer the essay´s questions an exhaustive survey was completed regarding convictions in Swedish courts classified as IPV during the year 2016. The population consisted of 163 convictions this year, and the loss was one conviction that was not located. 

    Results found in this essay shows that a man who does not use an explanation for his behaviour is liable to pay damages, but lesser amounts than a man who explains his behaviour. Other results show that in cases where the offender was under the influence of alcohol, at least under one of the charges, was convicted to a shorter prison sentence and was liable to less damages. Descriptive data generated from the study shows that more than half of the men was living together with children in their households. Furthermore; solely in half of the convictions was the occupation of the man described. Of these 81 convictions that mentioned occupation were only 29 % of the men in labour and 14,8 % either unemployed or on sick leave at the time of the proceedings.

    Et studie om hvilken effekt Range of Motion i en ankel-fod-ortose har på dynamisk balance hos stroke patienter2018Student paper other, 10 HE creditsStudent thesis
    Abstract [en]

    After a stroke, gait and balance are often affected and an orthosis is typically required to facilitate postural control. This study has been conducted to examine how the Range of Motion in an Ankle-Foot-Orthosis (AFO) impacts on stroke patients’ dynamic balance. It was hypothesized that better dynamic balance would be recorded when individuals were wearing a flexible AFO. The tests that was used in this study were the Timed Up and Go test (TUG), and the Center of Pressure (CoP)/Center of Mass (CoM) inclination angle, both in Anterior-Posterior (AP) and Medio-Lateral (ML) planes. The three patients participating in this study were all users, or had been users of AFO’s, and during the study they were asked to wear a customized AFO with the possibility to change the settings to open, flexible and rigid ankle joints. The order was randomized within each patient. No clear pattern was observed across all patients, either in the TUG test or CoP/CoM inclination angles. Further studies are required to explore the impact that AFO flexibility has on dynamic balance in individuals who have had a stroke.

    En ny modell för att beskriva den posturala kontrollen hos underbensamputerade2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: För att minska risken för fallrelaterade skador hos amputerade är envaliderad modell som beskriver och undersöker balans viktigt. The invertedpendulum model (IPM) är en validerad modell som beskriver människans posturalakontroll vid stående. Validiteten är ifrågasättbar för transtibialtamputerade då desaknar aktiv plantarflektion i ankelleden. Därför hypotiserade Rusaw och Ramstrand(2016) att en ny modell krävdes.Metod: Protesanvändare (n = 8) och en kontrollgrupp (n = 7) utförde tre tester,stående på två kraftplattor, under tre olika villkor (totalt 9 tester). Villkoren var ögonöppna, ögon stängda samt feedback på viktfördelning. Data samlades in ochkorrelationskoefficienterna beräknades för att undersöka skillnaderna mellangruppernas medelvärden. För att validera modellen kinetiskt använde Alinder ochEdholm mekaniska begränsningar på kontrollgruppen. Detta i form av en anordningsom låste centre of pressure till en specifik punkt.Resultat: Som hypotiserat blev korrelationen mellan vänster sida för kontrollgruppen(r = -0.557) och den intakta sidan för protesbrukarna (r = -0.423) negativ. Dessutomvar korrelationen och för både protesanvändarna (r = 0.024) och kontrollgruppen (r= 0,207) nära 0 på högersida.Slutsats: Rusaw och Ramstrands (2016) nya modell kunde valideras utifrån resultatetpå denna studie.

    Interventioner med hund för personer med demens: En scoping review2018Independent thesis Basic level (degree of Bachelor of Fine Arts), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: In dementia people gets affected by different behavioural, psychological, and physical symptoms that affect their ability to participate in activities. Together with these symptoms a decreased motivation may interact on the possibility of occupational performance. Earlier studies indicate a positive effect of animals on wellbeing and occupation performance. Through occupational theory the connection between the experience and possibility to activity are seen as a foundation for everyday activities.

    Purpose: The aim was to describe interventions with dogs in relation to persons with dementia.

    Method: Scoping review design, limited to dementia, all ages, and both sex. Inclusion criteria was; not more than sex year old, English, Norwegian, Danish, and Swedish articles. Quantitative, qualitative and grey literature through AMED, CINAHL, MEDLINE, PsychINFO, Anthrozoös, and full text by Google Scholar. Exclusion criteria was other types of diseases or injuries, and studies older than sex years.

    Results: Most common intervention with dog, during treatment of dementia, are dog-assisted activity during a longer treatment period. The interventions are implemented during 30-60 minutes, 2 times a week for 6-12 months through physical, sensory, social and cognitive stimulation. In treatment of dementia interaction with dogs may promote occupational performance through a positive effect on depression and quality of life. Interventions with dogs may reduce the presence and appearance of depression and may promote cognitive ability. They may promote to higher degree individuals with severe dementia, cognitive disability and anxiety. Intervention with dogs may promote participation in daily activities through a decrease of presence of depression.

    Conclusion: Most common intervention with dogs are dog-assisted activity during a longer treatment period. Interventions with dogs may promote social and physical interaction through cognitive stimulation. Dogs may have a positive influence on depression, and quality of life. The dogs may also have a positive influence on anxiety and activities in daily living and may also promote cognition in severe cognitive limitation, and to a higher degree with severe depression, and dementia.

    Normkritik och intersektionalitet på socionomprogrammet: Lärares erfarenheter och upplevelser av undervisning om normkritik och intersektionalitet2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    One might say that it is of significant importance for social work practices that students, during education to become social workers, acquire knowledge of the aspects of power that occur during the meeting with clients. Anti-oppressive education as norm criticism and intersectionality addresses these aspects of power, thus points out the importance of good conditions for such education. The purpose of this study is to investigate how the teaching is conducted in practice and examine teachers’ experiences on how to teach about norm criticism and/or intersectionality in social work education. A qualitative study has been conducted with teachers who have experience in teaching about norm criticism and/or intersectionality. Nine semi-structured interviews have been conducted with teachers from different institutions. The study material has been analyzed on the basis of norm critical pedagogy and anti-oppressive education. The study highlights the importance that students develop critical thinking, which is imperative in order to question known “truths” and to continuously apply the process of critical thinking. For a deeper understanding, the students must understand the of power, norms and structures as well as how they affect and are influenced by them. This is achieved by the students turning the critical look toward themselves. There are organizational barriers to the teaching about norm criticism and/or intersectionality due to the lack of resources. For example, the student groups are too large and there is time constraint in designing the teaching in a constructive way. The conclusions are that teachers believe that knowledge about norm criticism and/or intersectionality is of outmost importance to achieve social change on a structural level. In order for students to gain such knowledge, the resources required must be made available to teachers. Therefore, to ensure that new models of teaching about norm criticism is practically implemented in social work education, the shortage of resources exposed in this study need to be considered when developing new teaching methods and during further research.

    Varför vill inte fler vara skyddsombud på byggarbetsplatser?2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: A stated problem in the construction industry is to recruit and keep safety officers. The lack of willing and engaged safety officers could result in lower safety at construction sites. The purpose of this report is to examine how the safety officers are currently experiencing their work environment and examine what can be changed to improve the situation. 

    The aim of this thesis is to find out what can be improved for more people to want to be a safety officer. This is examined by the main question: Why do not more people want to be a safety officer? The main question is answered by two sub-questions:

    • Which difficulties exists in the role as a safety officer? 
    • What changes needs to be done to improve the situation?

    Method: To reach the aim of the report a case study was performed. The case is Skanska Hus Väst and is limited to the profession safety officers. The method of investigation is interviews and questionnaires, which are qualitatively conducted. The interviews are conducted with the chief safety officers. The chief safety officers can see the broad picture of the situation since they continuously keep contact with all the construction sites in their district. The questionnaires are sent to all the local safety officers in all the districts in the entire region. 

    Findings: One reason for the lack of engaged safety officers is that they do not receive the necessary respect and response from their coworkers. It makes them feel alone. There is no acceptance for safety work and the time that is needed, which give the safety officers a bad conscience when they are forced to leave their work partner. To improve the situation the safety officer’s must receive more respect from their coworkers. Knowledge and acceptance concerning safety must be improved among all workers on the construction site. The safety officers need to feel that they can, and are allowed to, influence the project. 

    Implications: To solve the problem the current safety officer’s situation must be improved. If the existing safety officers are pleased they will give a positive picture of the role to their coworkers, the potential new safety officers. The safety officers’ situation can be improved by the points that follows:

    • The safety officers must receive more respect from others in the construction site. 
    • The safety officers should advantageously be placed separate from the time plan of the project.
    • The safety officers should be involved in an earlier stage of the project. 

    Limitations: The report has been limited to only examining the role of the safety officer and their own perspective. The views of safety officers from the perspective of other roles at the construction site has been omitted from the thesis. The report does not investigate how to perform the changes.

    HAND- OCH ARMVIBRATIONSSKADOR INOM BYGGBRANSCHEN BETEENDE – EN ORSAK TILL ATT PROBLEMET KVARSTÅR2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The issue with vibration injury have been around in the construction industry for as long as there have been vibrating machines available. Today it’s up to 51 percent of all strain injury’s that’s vibration-related, according to AFA. The most common thing is that men in the ages of 47-49 who suffers from vibration injury, but in recent years the injuries have crept down in the ages. The injuries that may emerge from excessive vibration exposure are circulatory symptoms (cold / white fingers), neurological symptoms (numbness, tingling, feeling impaired) or a combination of these. Carpal tunnel syndrome is also a consequence of too high exposure. This paper will investigate whether may be a behaviour that is behind the high vibration exposure and if it in such case can be broken. The operator’s knowledge and understanding of the operating hours for the machines have also been studied.

    Method: A literature study has been carried out at work. Then a total of twelve interviews have been conducted, eight with constructions workers, three with site managers and one with a power tool manufacture. A smaller document analysis of job planning has also been made.

    Findings: This study shows that behaviour is behind the fact that operating times are exceeded, and constructions workers are exposed to vibration exposure above the allowed limit. It is also clear that the knowledge and understanding of the workforce and the management team needs to be increased in operating hours and how to read vibration acceleration on machines.

    Implications: The industry should require customers and companies to provide space for the costs that are incurred when driving times are met. In this way, behaviour can be broken by giving time for special moments. By training their staff about vibration damage, the company can get a more competent and understanding staff in exchange.

    Limitations: This survey is not company-specific, which means that the results can be applied to most construction companies in Sweden. The study only examines hand and arm vibration damage, while whole body vibrations have been ruled out.

    Keywords: Vibrations injury of hand and arm, Theory of Reasoned action, Job planning, Swedish work environment authority regulation, Input Value and Limit.

    ÅTERANVÄNDNING AV SCHAKTMASSOR2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte: Återanvändningen av schaktmassor inom anläggningsbranschen är i dagsläget begränsad. Bland annat på grund av otydliga regelverk samt låga kostnader och hög tillgänglighet av jungfruliga material. Trots att schaktmassor har en hög potential att återanvändas finns det andra alternativ för överskottsmassor som uppstår i ett projekt som är mer fördelaktiga för entreprenörer. Svårigheterna kring återanvändning av schaktmassor är det som skall undersökas och målet med rapporten är följaktligen att undersöka möjligheterna att främja återanvändning av schaktmassor inom anläggningsbranschen. Målet kommer att besvaras med hjälp av två frågeställningar: (1) Hur kan återanvändningen av schaktmassor främjas inom anläggningsbranschen? (2) Hur kan en återanvändningsterminal öka återanvändningen av schaktmassor?

    Metod: Metoderna som valts för att samla empiri till studien är litteraturstudie, dokumentanalys och intervjuer. Litteraturstudien och dokumentanalysen skapade en kunskapsuppbyggnad inom ämnet som bland annat låg till grund för utformningen av intervjuerna. Intervjuerna har genomförts tillsammans med tio respondenter från åtta olika företag inom anläggningsbranschen.

    Resultat: De regelverk och lagar som finns kring hanteringen av schaktmassor ses som det största hindret för återanvändningsmöjligheterna. Svårigheterna att få ekonomisk vinst i återanvändningsprocessen samt långa transporter är också bidragande orsaker. Även de geotekniska egenskaperna på schaktmassornas kan vara problematiskt, dels för att massorna skall klassificeras enligt sin byggbarhet samt att de skall vara jämförbara med jungfruligt material.

    Konsekvenser: Slutsatserna som dragits utifrån studien är att det krävs ett ökat samarbete inom branschen för att återanvändningen av schaktmassor skall främjas. Tydligare kommunikation behövs samt att planering kring masshanteringen bör ske i ett tidigare skeden i projekten. De regelverk och riktlinjer som finns idag behöver omarbetas för att bli tydligare och möjliggöra för ökad återanvändning. En återanvändningsterminal av storskalig verksamhet som placeras centralt skulle bidra till att återanvändningen av schaktmassor ökar vilket minskar miljöpåverkan och gynnar branschen.

    Begränsningar: Studien är begränsad och utförd inom Jönköpings län och intervjurespondenterna är valda utefter de verksamheter som verkar inom länet. Arbetets generaliserbarhet begränsar sig till Sverige eftersom att regelverk och tillvägagångssätt gällande hantering av schaktmassor ser olika ut i andra länder.

    Nyckelord: Utgrävd mark, återanvändning av schaktmassor, återanvändningsterminal, återanvändning av bergmaterial.

    Ledarskap för ökad effektivitet i byggproduktion2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The population of Sweden is steadily increasing, which raises the need for new infrastructure and new buildings. To meet these demands the construction industry must become more efficient. According to several researchers, better leadership can be a part of accomplishing this. Discussions regarding leadership are mostly from the leaders’ perspective and usually the decisions about what kind of leadership is needed is made by the leaders themselves. Not very often do the followers get a chance to share their thoughts on what they need to become more efficient. Earlier research shows a correlation between motivation and efficiency. Therefore, this study attempt to find out what motivates construction workers.

    This study intended to examine what type of leadership construction workers think they need to become more efficient. The study’s aim was to contribute knowledge about how leadership can increase the efficiency on the construction site.

    Method: Two methods for data collection were used. A literary review based on effective leadership and interviews with construction workers about their thoughts on what type of leadership would increase their motivation and efficiency.

    Findings: This study has, by answering the research questions, contributed knowledge about how leadership can increase the efficiency on the construction site. The construction workers are of the opinion that their leaders have a big impact on their efficiency. The leaders’ knowledge and experience of the production phase as well as their ability to communicate and plan ahead were all seen as factor that affect their efficiency.

    The literary review for this study found 23 effective leadership traits. According to the construction workers the leadership skills that contribute the most to their motivation and efficiency are humility, relationship-management, and self-awareness.

    Connecting the construction workers responses to the efficient leadership theories showed that the most relevant theories for increasing the workers motivation and efficiency are Transformational and Servant Theory. The theory of Servant is the most relevant since it focuses on the followers.

    Implications: To increase the efficiency one must focus on the people in the industry. By changing the leadership based on the construction workers' opinions their efficiency can be increased. Therefore, it is recommended that leaders on the construction site work with the leadership theories Transformational and Servant and that they develop the effective leadership traits, especially the traits the construction workers find most important.

    Limitations: This study was limited to the leadership from the site supervisor to the construction workers. The focus was on what type of leadership the construction workers wanted to become more motivated and efficient. Furthermore, the study was limited to four leadership theories and effective leadership traits.

    Keywords: Efficiency, motivation, effective leadership traits, Contingency Theory, Transformational Theory, Transactional Theory, and Servant Theory.
