    Colleagues or competitors?: A cross-cultural study about the effects of commission based salaries in Sweden vs. the U.S.2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    An important issue that managers are facing in today’s intensive business environment is how to compensate their employees to keep them motivated. The trend is to be rewarded for the individual performances, which has increased the usage of commission based salary systems. Previous research suggests that commission salary provokes internal competition, while it damages cooperation. However, the main issue in feminine and masculine societies is what motivates people, which indicates that the effects of commission based salary systems needed to be examined from a cultural perspective. Therefore, with the main aim was to enhance the understanding of this, the problem was addressed by the overreaching research question: How do commission based salary systems affect cooperation and internal competition in masculine and in feminine societies? To answer this, empirical data was acquired from Sweden and the United States. Sweden is recognized as the most feminine society, where social motives are dominating. The United States on the other hand, is recognized as a masculine society that encourages competition and where money is the main motivator. The empirical data derived from personal interviews with real estate agents that work with commission salary. Three case companies within each country were included in the study and three interviewees within each company participated. The findings showed that commission salary tends to increase the work effort, limit the cooperation, while it increases the internal competition. Nevertheless, the effects it has distinctively differs between the societies. In Sweden, the importance of group cohesion and interpersonal relationship results in a higher level of cooperation than in the United States. Despite that commission salary evokes internal competition, colleagues are colleagues above all in Sweden. In the United States however, cooperation mainly occurs when it serves the individual performances. Here, money and the own success are what matter the most and due to the competitive mindset, internal competition becomes significantly more intensive in the United States than in Sweden. In contrary to Sweden, commission salary can turn colleagues into competitors, for better or for worse.

    Kvaliteter i elevtexter: Att skriva med olika verktyg i årskurs 22017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Abstract

    The aim of the study was to investigate the quality of pupils’ narrative texts written either by hand or on a tablet. The questions concern which structures are characteristic of the texts as a whole and what is distinctive about hand-written texts and those written on a tablet. To investigate this, 46 pupil texts from grade 2 were analysed. Each pupil in the class wrote two texts, one with each writing tool. The overall theoretical approach in the study is dialogism, which views all utterances as being related to each other. In this study that means that the pupils received teaching about how to write a story, and then wrote stories of their own. Relief theory, which has its foundation in dialogism, was used as analytical framework. With this model, analyses are made of the text as a whole. The overall structure and focus of the text are regarded as the foreground and the additions and expanded details supporting these are viewed as the background text. This interaction between foreground and background gives the relief perspective. Proceeding from relief theory, the structures of the texts in their entirety were analysed. At the intermediate and local level of the texts, dialogues and connectives were analysed, along with the number of unique words and the total number of words. The relief of the texts was analysed in terms of quality at global, intermediate and local text level. The relief analysis revealed that three different categories of relief could be identified in these texts. The result shows that the difference in quality concerns how the backgrounds are expanded. The results of the study show that there are differences between the pupils’ handwritten texts and texts written on a tablet, but the differences are small. The biggest differences concern the number of unique words and the total number of words. The texts written on a tablet contain both more unique words and more words in total than texts written by hand.

    Nihilismus, Sprache und Wahrnehmung: Zur Anthropologie Lacans und Merleau-Pontys2000Doctoral thesis, monograph (Other academic)
    Abstract [en]

    In my doctoral thesis, I diversify so-called deviant behavior of children by means of a critical concept of nihilism and lead them back to a certain intellectual origin, namely, to the idealistic thinking tradition, which leads to the Philosophy of Lack and Not. I see this philosophy in the theories of Lacan and Merleau-Pontys, diametrically opposed to the idealistic thinking tradition. Departing from the ineradicable non-consciousness of man, Merleau-Ponty works out the laws of perception and Lacan the laws of language. As I refer to these authors and to the Philosophy of Not, my investigation proceeds not simply from the human capacity to be educated, but from the fact that in certain cases this capacity is to be yet established. The Philosophy of Not, complemented by the methodology of a cartography of negative experiences developed by the artist Robert Smithson, open up new surprising theoretical approaches to (educational) practical challenges. Starting from the laws recognized by Merleau-Ponty and Lacan, an explanation and possible forms of dealing with nihilistic behavior can be derived.

    Mobile Payment Use and Mobile Payment Transactions by Older Adults: A Qualitative Study2017Independent thesis Advanced level (degree of Master (Two Years)), 80 credits / 120 HE creditsStudent thesis
    Abstract [en]

    The research outlined in this thesis focuses on the effects of implementation and use of mobile payments as experienced by older adults aged 55-75, as qualitatively examined through research interviewees (hereafter participants of this study) made up of individuals with varying cultural and technological backgrounds, who are acclimated to Greece’s culture and have lived within the country for at least a decade. Their own perception and reception of the practice allows for a more comprehensive look into the practical application of the technology within the country. No empirical studies are available on the aforementioned topic, despite the high importance and need for such study. Therefore, this research is carried out through a literature review. It then analyzes two models namely technology acceptance model (TAM) and unified theory of acceptance and use of technology (UTAUT) model. It applies a phenomenological research method and provides us with a more concise, contextualized background into the widespread application of m-payment and m-commerce within the country. This research contributes new knowledge to m-payment and m-commerce through theoretical and empirical research and benefits the interpretation of a recently emerging phenomenon. The research results are useful to various groups associated with mpayments and m-commerce. Future research directions concerning this phenomenon involve the reception and enhancement of m-payment methods by older adults.

    Aja Baja Bu: Trygghetsbelysning för barn2017Independent thesis Basic level (degree of Bachelor of Fine Arts), 10 HE creditsStudent thesis
    Abstract [en]

    In this project I’ve worked with the brand Kid´s Concept where their brief were for me to develop an innova ve lamp that would dis nguish itself from their current ligh ng products. Through research and sketching the inten on of the project became to develop lamps that would favour children suff ering from night terrors. The concept is a lamp that sleeps during the day but stays awake at night and fi ghts montsters. Aja Baja Bu is a lamp that helps the child feel safe while the playful expression of the lamp encourages children to interact with it. The two characters are open for imagina on and makes it possible for children to create their own stories about them. During the day Aja Baja Bu will be exhausted from staying up all night and the child must restore its energy by giving it its magical crown or horn. Thus the child will feel connected and gain trust in the characters.

    DEZK: Skrivbord och förvaring för små lägenheter2017Independent thesis Basic level (degree of Bachelor), 10 HE creditsStudent thesis
    Abstract [en]

    In this project I set out to favor people living in small spaces but who are in need of a substantial desk in their

    homes. With sketches, scale-models and interviews I explore what problems a student in Seoul, South Korea,

    experience and what role design can play in aiding his situation. I will describe how i choose materials, make

    decisions about the design of certain details and how I take an idea of a folding desk and realize it to create a

    mobile drawer unit with a foldable workspace. A workspace for sitting and working or for being a part of the

    drawers storage while also allowing the user to work standing up.

    Vardagsglas: För kökets trädgård2017Independent thesis Basic level (degree of Bachelor of Fine Arts), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    When I founded my concept about the kitchen's garden, my project expanded to become two. This meant that my graduation project has been about working with two different companies and developing two different glass products. The companies Skrufs glasbruk and Artilleriet have been my outsoursers. The project has been a challenge in the form of different starting points and delimitations, which has meant that I have explored two different directions in design aesthetics. The expression in the products has been my priority as I recall the companies strive for different aims, which has not always been the easiest task.

    My concept of functional glassware in The Kitchen’s Garden is based on the importance of indoor cultivation and gardening, which secures the knowledge of the origin and care of the vegetables as well as the importance of emphasizing other types of vegetation in the kitchen.

    A great part of my project has been to explore different methods of highlighting the glass properties to emphasize the transparent glass itself. Transparent glass has the ability to color itself depending on its context and how it is used, which gives a personal variation which contributes with options for the user to decide.

    Observed Coherent Triads in Swedish Social Work Practice. Analysis of Observed Successful Collaboration Beneficial for Clients in Swedish Juvenile Care2017In: BOOK of ABSTRACTS, EUSSSI 2017, The 8th Conference of the European Society for the Study of Symbolic Interaction Studying Everyday Life: Generic Dimensions of Interactionist Inquiry, Lodz, Poland, 2017, 9-10 p.Conference paper (Refereed)
    Abstract [en]

    Previous research on collaboration in social work practice shows that conflicts among collaborating authorities and organizations and that include cooperating actors are common. In this study, I have analyzed a successful dimension of the phenomenon “cooperation.” The purpose of the study is to analyze examples of successful cooperation in Swedish social work practice. This study presents an analysis of factors of “successful collaboration” as described in the field notes of the study and that can be interpreted as beneficial for the youth in question. A total of 119 field observations of organized and informal meetings form the empirical basis for this study. The observations took place before and after these meetings and during visits to youth care institutions in Sweden, social services offices, and the Swedish National Board of Institutional Care. The factors used in the empirical material of this study serve to define successful cooperation that makes visible actors belonging to at least three different categories (coherent triad in the collaborative act). Constructing and reconstructing a collaboration success is a dynamic, interactive process. Coherent triads and success points of interest that are beneficial for the young person in the situation also create the image of a positive development for the young person. In this way, common identities of interplay that are useful for the young person are being created and elucidated. The physical presence of the young person in these situations is especially important factor for the “successful collaboration.”

    School as a protection factor: An analysis of achievements, obstacles, collaboration, and identities in senior high school work with students who use alcohol and drugs2017In: BOOK OF ABSTRACTS. The 9th International Conference of the Faculty of Education and Rehabilitation Sciences University of Zagreb / [ed] Gordana Hržica; Ivana Jeđud Borić, Zagreb, 2017, 192-193 p.Conference paper (Refereed)
    Abstract [en]

    This research project is inspired by ethnographic methodology, where researchers reside within the environments, situations, and interactions they want to learn about. By observing what happens, listening to what is said, asking questions and collecting documents in the practice, the researcher can come to an understanding of the participantsʼ experiences. Adolescence is a unique period in which there is a high potential to influence and change both issues at school and drug abuse problems. However, it may require productive collaboration between professional in the social services and treatment centers and school staff. The environment at school can help create stability in a drug-abusing youths’ life, and the combination of education and treatment is a key factor necessary for these students to build independence. Much remains unknown about improving schooling for students with alcohol and drug problems and the factors involved should therefore be investigated. This project aims to identify and analyze (1) factors in practical and organizational work at senior high schools that are obstructive and promotive to students with alcohol and drug problems; (2) the circumstances teachers and other professional actors in the Swedish school system need to promote the success of students with alcohol and drug problems; (3) implications of school attendance for inclusion, learning, and change in these youths; and (4) implications for the identity construction of these young people related to school situations. By examining the details of the work done by professionals, the results from this project will provide missing knowledge about how to improve schooling for young people with alcohol and drug problems and how this contributes to their inclusion and participation in society. Our hope is that the project will identify conditions and opportunities needed to support young people with alcohol and drug problems in senior high school. Additionally, the information obtained will be used to develop a model for improved collaboration between schools, social services, and various treatment services to improve graduation rates for young people in the target group. In this specific target group, studies are lacking that identify factors that promote or obstruct such cooperation.

    ICT in a Public Organisation - A study in Greece2017Independent thesis Advanced level (degree of Master (Two Years)), 80 credits / 120 HE creditsStudent thesis
    Abstract [en]

    The thesis presents a research in the Public Power Corporation S.A. – PPC in Athens, Greece. The main purpose of this study is to examine the employees of PPC use of the IT (Information Technology) system and whether the system supports, helps and facilitates their work or generate problems to them in their daily work. The IT system that is being used in the PPC is SAP (Systems, Applications and Products) and was implemented about two years ago, in 2015. Therefore, my intention is to explore and analyze the usefulness and efficiency of SAP and detect the advantages as well as the problems of this IS which have impact on the quality of the customer services. Furthermore, the latest years that the financial crisis occurs in Greece the common interest for public firm’s development, became a motive for me to propose and undertake this research due to the fact that these kinds of public companies can contribute to the economy of Greece. For the research, I used the interpretive paradigm. The methodology used is ethnography and the two methods are the interviews and the observation. The research was conducted in different departments of PPC. The participants are the employees, the managers and one Director of PPC. The data collected from the two methods are analyzed by using the Lichtman’s six step of analysis. After the data analysis, the results indicate that there are vital problems in the PPC in relation to the use of the IT system which in some cases are more than the advantages. The users of SAP have expressed their experience in relation to the implementation of the new IT system. They recognize the importance on using such an advanced IT system but on the other hand, they express the limitations and the problems because of the vital problems on PPC.

    Nedskrivning av Goodwill: Är nedskrivning av goodwill enligt IAS36 förenlig med IFRS:s krav på neutralitet?2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Since year 2005 all Nordic companies on a regulated stock market needs to present their accounts according to the IFRS-standards by IASB. This has affected the management of goodwill that now needs to be exposed for an impairment test every year.  This paper handles the impairment of goodwill in Nordic companies to test their ability to follow IAS 36 in the IFRS-standards and neutrality in The Conceptual Framework for Financial Reporting. Goodwill was earlier exposed to linear depreciation according to the national rules, while nowadays it needs to be impaired every time it’s warranted according to the calculated future cash flow. This creates an opportunity for companies to affect the accounts, an opportunity that can be explained by the Agent theory and Big Bath. How companies handle this change in accounting is tested to see if there is any relationship between goodwill impairments and future cash flow. Earlier studies have been made on the American market by Jarva (2009) and his model to calculate future cash flow is used in this paper.

    Improving the Visibility and the Accessibility of Web Services. A User-Centric Approach.2017Independent thesis Advanced level (degree of Master (Two Years)), 80 credits / 120 HE creditsStudent thesis
    Abstract [en]

    The World Wide Web provides a well standing environment in any kind of organizations for exposing online products and services. However, no one ensures that web products or services which provided by organizations or enterprises, would receive the proper visibility and accessibility by the internet users. The process of Search Engine Optimization examines usability in design, architecture and content that an internet-based system has, for improving its visibility and accessibility in the web. Successful SEO process in an internet-based system, which is set under the paternity of an organization, ensures higher recognition, visibility and accessibility for the web services that the system provides to internet users.

    The aim of this study characterized with a trinity of axes. In the first axe, an internet-based system and the web services that provides is examined in order to understand its initial situation regarding its visibility and accessibility in the web. In the second axe, the study follows a user-centric approach on how and in what way the examined system could be improved based on its users’ needs and desires.

    After the encapsulation of needs and desires that the users expressed as regards the usability of the system in design, architecture and content, the third axe takes place. In the third axe, the extracted needs and desires of users are implemented in the under-examined system, in order to understand if its visibility and accessibility has improved in the World Wide Web.For the completion of this trinity of axes, the Soft Systems Methodology approach is adopted.

    SSM is an action-oriented process of inquiry which deals with a problematic situation from the Finding Out about the situation through the Taking Action to improve it. Following an interpretative research approach, ten semi-structured interviews take place in order to capture all the participants’ perceptions and different worldviews regarding of what are the changes that they need and desire from the examined system. Moreover, in this study, the conduction of three Workshops, constitute a cornerstone for implementing systemically desirable and culturally feasible changes where all participants can live with, in order to improve system’s visibility and accessibility in the internet world.

    The results indicate that the adoption of participants’ needs and desires, improved the levels of usability, visibility and accessibility of the under examined internet-based system. Overall, this study firstly contributes to expand the knowledge as regards the process of improving the visibility and accessibility of internet-based systems and their web services in the internet world, based on a user-centric approach. Secondly, this study works as a practical toolbox for any kind of organization which intends to improve the visibility and accessibility of its current or potential web services in the World Wide Web.

    High energy gamma ray emission and multi-wavelength view of the AGN PKS 0537-4412017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis describes the analysis of Very High Energy (VHE) emission from the Active Galactic Nucleus PKS 0537-441. It also aims to put the results in a wider context by implementing previous work done on this source. The data chosen for the analysis is provided by the Fermi-LAT satellite and covers the energy range between 300 MeV and 300 GeV. Initially a lightcurve of the received flux from the source was generated, containing data from August 2008 to April 2017, with a mean flux of 4∗10−8 photons per second per squared centimeter. The lightcurve contained sections of different flux intensities giving periods of special interest, such as a flaring period at August 2008 to August 2011, an enormous flare at April 2010 and a less active period between April 2013 - January 2016 that could be identified for further investigations. The differences in observed flux over time was tested and PKS 0537-441 was found to be a significantly variable source. Spectral Energy Distribution (SED) analysis was performed over both the entire period as well as over the selected subperiods and fitted against models using the tools provided by the Fermi Science Support Center (FSSC). The models used in the fitting was PowerLaw2, LogParabola and PLSuperExpCutoff and the best fit for the data was obtained from the PLSuperExpCutoff, except for the less intense period where the LogParabola gave the best fit. The result from the SED analysis was integrated with results from previous work done on the source, ranging over multiple wavelengths in order to get a SED which spanned over the entire electromagnetic spectrum. Finally, modeling of this multi wavelength SED was performed in order to obtain parameters for the physical processes involved in the creation of the radiation received from PKS 0537-441.

    There's a new sheriff in town!: En kvalitativ studie om OECD:s implementering av den största internationella skattereformen på över hundra år2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The international tax law has for decades been lagging behind the rapid pace of the globalization, consequently not being able to regulate multinational corporates’ behaviour regarding allocation of profits. This asymmetry has eroded states’ tax bases since multinational corporations has been permitted to allocate profits in any given nation, whereby tax planning has developed a widespread problem within the global business-arena. In order to curb the situation OECD has formulated a new tax regime named Base Erosion Profit Shifting (BEPS), which includes 15 action points with the main purpose to create equality regarding tax collection. Corporations are now facing an immense alteration whereby the global tax-climate is changing.

    The main purpose of this study is to analyse the impact of the implementation of BEPS Action 7 regarding corporate structure and profitability of Swedish multinational corporations. Furthermore, the study aims to provide guidelines for companies for the forthcoming implementation of BEPS Action 7.

    In order to fulfil the purpose of the essay we have conducted a qualitative study, which is based on a hermeneutic examination method with an abductive approach. Furthermore, the qualitative study has been conducted by semi-structured interviews with four Swedish listed corporations that have a distinct international connection. 

    The main findings’ regarding BEPS Action 7 is that the implementation can have a certain impact on both corporate structure as well as profitability. Changes within the corporate structure will mainly occur if there is situations of double taxation or if the profitability of the corporation gets negatively affected. Furthermore, the study implies that costs will increase as a consequence of Action 7 due to increased onus regarding administrative tasks, increased resource requirements and more disputes and audits arising as a result of the implementation.

    Waste Management in the Mekong Delta: Characterisation and evaluation of organic waste2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This degree project investigated landfills that takes care of municipal solid waste in an area around the Mekong delta, namely An Giang province, Vietnam. The main objective for this study was to provide basic work in order to create a discussion with the local food markets to separate the household’s food waste from the rest. Such a discussion is possible to create through collaboration with local authorities and inform or guide stakeholders on how waste management can be improved, out of existing knowledge from Sweden. Therefore, this study aims to illuminate and give knowledge for improvements in questions regarding efficiency, organisation, participation, recycling and opportunities associated with a more efficient waste management system.Since a significant percentage of the household waste generated in Long Xuyen City, An Giang province are organic, the opportunity to convert organic waste into soil amendments was examined. Leachate from one of the landfills in the area was also analysed in order to get further understanding for its composition, focusing on organic parameters.

    Abstract [en]

    Purpose: The purpose with our study is to make an example of how discourses about leadership and entrepreneurship can be expressed in the everyday life of a company in the Swedish landscape Småland.

    Method: We have used an abductive and a qualitative research approach. In four days we shadowed the CEO Mr. Samuelsson from Grimslöv Skogstjänst AB. During those days we conducted qualitative and unstructured interviews with the CEO.

    Conclusion: According to the example in this study it shows that discouses about leadership and entrepreneurship can be expressed in many various ways. Based on Samuelsson’s opinions and actions in the everyday worklife we observed his way of leadership was that (1) all people should be and feel involved, (2) take advantage of the available resources and opportunities, (3) feelings and thoughts in focus, (4) important to have a positive and helping atmosphere, (5) a balance between the company and the employees, (6) partially be a classic self-employed person with focus on profitability and interest, (7) try to get used to delegation while maintaining the company’s quality and (8) communicate the ideas and thoughts as well as make use of emotions. With these discourses about leadership and entrepreneurship our conclusion is that out view of the småländska ledarskapet is a combination of leadership and entrepreneurship, exerted in an organization, that contributes to development to society.

    Fekal mikrobiell transplantation (FMT) vid fetma och metabolt syndrom2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In Sweden, 14% of the population suffer from obesity, and it is a growing health problem throughout the western world. Obesity can lead to cardiovascular disease, and today there is no effective drug treatment for obesity. In animal studies, obesity is associated with changes in the composition of the intestinal flora and metabolic function. Our state of health is reflected by the composition of the microbiota, which is influenced by environmental factors. Thus, manipulation of the microbiota in the intestine via fecal microbial transplantation (FMT) could be a treatment option for obesity and its sequelae. Such animal studies are published, and there is one study conducted on humans with metabolic syndrome where the health effects of FMT was evaluated. The purpose of this literature study, which has a pharmaceutical focus, was to evaluate whether FMT could have a beneficial effect on the intestinal flora of individuals with obesity and/or metabolic syndrome. Of the eight articles, good effects of FMT could be seen in the treatment of obesity and metabolic syndrome. The food had a bearing on the result; with an, what is considered, unhealthy diet, an effect of FMT could not be seen. What gave positive health effects was butyrate producing microbiota as well as methanogens. However, more studies need to be done to find out what role the intestinal flora has on body weight and energy homeostasis, as well as what roles different microbiota have, to get an effective composition of microbes for FMT.

    Pursue Social and Ecological Sustainability Through Urban Foraging: Design for Foraging: Plantarum, a Digital Mapping Platform2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Food production and food consumption have been shown to have a great impact on

    our ecosystem. Human beings have been exploiting the planet in order to feed

    themselves. This will have negative consequences for future life on the planet. Modern

    food production and consumption are among the main causes of natural resource

    exploitation and the problem is very likely to increase. Indeed, during the past thirty

    years, the global population has grown exponentially by almost one billion every

    decade, and it is still growing at the same pace. This demographic explosion means

    that dramatic shifts in the production and consumption of food will be required.

    Working with food is a great chance to achieve or at least lead towards a condition of

    recovering, understanding the world around us and managing our natural resourcesÅ.

    Increasing control and efficiency in food production and consumption cannot solve

    the problem. There is a much broader spectrum of causes contributing to the ecological

    decline. It is necessary to look beyond the technological and economic aspects. It is,

    therefore, necessary to focus on cultural and behavioural causes, promoting the

    involvement of local peopleÇ.

    With this in mind, this research explores the potential of urban foraging for generating

    social consciousness about ecological sustainability using design as method of

    intervention, and involving food consumers in the process of production and

    consumption of food in a more sustainable way. In order to do that, this research

    focuses on a small scale urban foraging project. In this case, by food, I refer to

    spontaneous food that grow in the natural urban environment of Växjö, and that can

    be used as a resource for citizens.

    In summary, this research aims to promote the involvement of local people and to

    support knowledge exchange in order to pursue socio-ecological sustainability.

    Engaging with more participants, the research gains the capacity of addressing

    complexity in a more coherent manner, and use its outcome as a usable resource for

    the local community that aims to promote its self-sustenance.

    Jakten på den rätta kompetensen: En kvalitativ studie om subjektivitetens roll i rekryteringssammanhang2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Att rekrytera rätt kompetens till rätt plats är lättare sagt än gjort. I sökandet efter rätt kompetens för en tjänst finns det utrymme för att subjektivitet och kategorisering präglar rekryteringsprocessen, vilket föranleder att arbetssökande riskerar att väljas bort på felaktiga grunder. Vi ville genom en kvalitativ studie öka vår förståelse för rekryteringsprocessen och undersöka om och i så fall hur en anonymisering i rekryteringen kan förändra subjektivitetens roll i processen och därmed även den homosociala reproduktionen. Med detta i åtanke ville vi undersöka ett företag som utger sig använda en omvänd kompetensbaserad rekryteringsmetod med tester i urvalsprocessen och som bortser från allt som inte är relevant för en tjänst. Detta genomfördes i form av semistrukturerade intervjuer med individer från två perspektiv. Två representanter intervjuades från vårt fallföretag som arbetar med rekrytering, medan fyra representanter intervjuades från olika kundföretag. Vi fann att rekryteringsprocessen alltid kommer präglas av subjektivitet så länge valet av kandidat görs av människor. Det är därför en fråga om att senarelägga subjektiviteten för att möjliggöra eliminering av den negativa effekt som riskerar att medföra att den bäst lämpade kandidaten väljs bort på felaktiga grunder. Denna senareläggning kan möjliggöras genom anonymisering av en arbetssökandes identitet och på så sätt kan även den negativa effekten av homosocial reproduktion förändras.

    Scrum och utmaningar: En kvalitativ studie om vilka utmaningar praktiserande står inför agila arbetsmetoden Scrum2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Agile methods are based on iterative development and fast delivery. This essay has beenconducted against practitioners who have experience working in accordance with agilemethods. As IT projects fail to a large extent and criticism is directed against Scrum,makes the topic of the essay relevant.

    The purpose of the study was to investigate the challenges that practitioners face when they work according to the agile method Scrum. To investigate this, a qualitative data collection was conducted by interviewing five respondents who have experience working with Scrum. Categorizations were made based on empirical theory, and the theory has then reinforced these categorizations.

    The investigation found that practitioners face challenges that can be divided into agile definition and Scrum, cooperation according to Scrum, as well as results and goals.

    Prenumerationsbaserad ekonomistyrning: En kvalitativ studie om hur företag med en prenumerationsbaserad affärsmodell styr för att skapa värde2017Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background and problem: The increasingly digitized world has created other conditions for doing business. A shift has been identified where the importance of value and how value is created has changed. The interaction between the company and the customer has become the place where value is distinguished and created. The traditional business model has been challenged to a greater extent by a business model based on subscriptions rather than one- time purchases of a product. A subscription-based business model means that companies have changed their approach towards customers and the ability to establish long-term relationships with customers is of great importance for achieving success. At the same time as a more changing environment requires that companies have a more external focus to be able to be agile and handle market changes. Through a greater focus on customers, the environment and the future a new type of management control system is required. Since the traditional management control system isn't adapted to today's companies and their conditions which makes it insufficient.

    Purpose: The purpose with this study is to describe and explain which contingencies that are characteristic for companies with a subscription-based business model and how these affect these companies value creation and management control system. The study also aims to contribute with knowledge to companies within the subscription economy.

    Method: The study's approach has been of a qualitative nature, where the research design has been in the form of an interview study where five different companies have been studied. The empirical collection consisted of semistructured interviews.

    Conclusion: The conclusion that can be made after the completion of the study is that subscription-based companies are affected by several contingencies that require a management control system with an external and future focus. The customer is a key part of the company's value creation and it is important that companies utilize and appreciate the customers opinions. The subscription based business model makes it easy for the customer to see if the company has taken charge of the customers opinions, since it is possible to distinguish already in the next month's delivery. This requires companies to have short decision-making processes, to a certain extent a decentralized organisation as well as an agile and process-focused operation method. Which is necessary for companies to deliver a constant development and improvement of their product.

    Hur hanterar sjuksköterskor stress på arbetet? En litteraturstudie om copingstrategier2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Arbetsrelaterad stress kan hindra att god vård kan ges till patienter. För att förebygga arbetsrelaterad stress behöver sjuksköterskor strategier och metoder som reglerar de negativa effekterna som stress medför.  

    Syfte: Syftet med studien är att belysa allmänsjuksköterskans hantering av arbetsrelaterad stress inom somatisk vård.

    Metod: Studien är en litteraturöversikt enligt Friberg (2012). Arbetet är baserat på 12 vetenskapliga artiklar som har kvantitativ ansats.

    Resultat: Resultatet är grundat i tre teman: Reducera stress genom problemlösning, Reducera stress genom att minska den emotionella effekten, samt Reducera stress genom stöd från kollegor och familj.

    Slutsats: Den copingstrategi som används bestäms av sjuksköterskan och situationen. Då alla sjuksköterskor och situationer är annorlunda fungerar inte en universell copingstrategi och måste anpassas till varje sjuksköterska. För att reducera stress kan sjuksköterskan reflektera över situationen och hitta en lösning. Sjukhusledningen kan även lägga in resurser för sjuksköterskor som kan hjälpa dem att hantera arbetsrelaterad stress.

    Orsaker till arbetsrelaterad stress utifrån sjuksköterskans perspektiv: - En kvalitativ litteraturstudie 2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Stress är en försvarsmekanism som förbereder kroppen för flykt eller kamp. I dagens samhälle kan däremot stressen leda till problematik både fysiskt och psykiskt för människan. Det är ett återkommande problem i sjuksköterskans profession och hanteringen av stress är olika samt beroende av vad som orsakar den.

    Syfte: Att undersöka orsaker till arbetsrelaterad stress utifrån sjuksköterskans upplevelser.

    Metod: En litteraturstudie som grundar sig i tio kvalitativa artiklar som handlar om arbetsrelaterad stress utifrån sjuksköterskans upplevelser. Analysmetoden som användes var Evans tolkande analysmodell.

    Resultat: Hög arbetsbelastning visas vara en huvudorsak till arbetsrelaterad stress för sjuksköterskorna vilket kunde påverkas av konkurrerande roller och tidspress. Ytterligare orsak var brist på stöd från kollegor eller verksamheten. En annan stressorsak för sjuksköterskorna var brist på samarbete mellan kollegorna vilket kunde orsakas av brist i kommunikationen. Resultatet redovisades i tre huvudkategorier: Högt ställda krav, otillräckliga tillgångar på arbetsplatsen och bristande relationer mellan kollegor.

    Slutsats: Studien har uppmärksammat verksamhetens betydelse för den arbetsrelaterade stressen hos sjuksköterskor. Detta problem kan inte enbart hanteras av sjuksköterskorna utan verksamheten måste inneha intresse för förändring.

    I smärtans grepp: En litteraturstudie av sjuksköterskans utförande av smärtanalys.2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Bakgrunden ger en läsaren en förståelse för yrket sjuksköterska och hens roll vid smärtlindring. Det ges också information om smärta, hur en smärtanalys kan gå till och behandling av smärta.

    Metod: En litteraturstudie gjordes som grundar sig i en kvalitativ innehållsanalys. Sökningen gjordes i två databaser där tio artiklar hämtades. Med en kvalitetsgranskning av artiklarna bedömdes artiklarnas kvalitet. Artiklarna med medelhög- och hög kvalitet användes.

    Syfte: Syftet med studien var att belysa vilka resurser sjuksköterskan behöver för att kunna utföra en smärtanalys.

    Resultat: I resultatet framgår det att sjuksköterskan bör inneha kunskap om smärta för att kunna utföra en god vård. Att använda sin kunskap och erfarenhet är nödvändigt för att kunna genomföra ett bra vårdande. Yttre resurser, så som team arbete och arbetsmiljö påverkar också vårdandet och hur sjuksköterskan utför sina uppgifter.

    Slutsats: För att behandla smärta hos en patient krävs goda kunskaper hos sjuksköterskan och ett tydligt samarbete med andra vårdprofessioner. Vikten av ett bra bemötande och en god kommunikation med patienten framkom för att undvika missförstånd och att undvika situationer där sjuksköterskan misstror patienten i behandlingen av smärta.

    ATT MÖTA DÖDEN SOM UNG: En kvalitativ litteraturstudie baserad på självbiografier om unga människors upplevelser av att leva med obotlig cancer2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Cancer är den näst största dödsorsaken bland människor efter hjärt- och kärlsjukdomar. År 2015 var det 23 455 personer som avled på grund av sin cancersjukdom varav 76 personer var unga människor. När en ung människa får en cancerdiagnos kan negativa känslor framkallas då livet förändras och framtiden blir oviss.

    Syfte: Syftet med studien var att belysa unga människors upplevelser av att leva med obotlig cancer.

    Metod: Studien är en kvalitativ litteraturstudie baserad på fem självbiografier om unga människors upplevelse av att leva med obotlig cancer. Självbiografierna är granskade och innehållsanalys har använt som metod i analysen.

    Resultat: De unga människornas upplevelser av att leva med obotlig cancer beskrevs genom fyra kategorier och nio underkategorier. Det framkom i resultatet att de upplevde att kroppen svek dem, att behandlingen gav negativa biverkningar, att relationen till andra betydde mycket och att det trots sjukdom är möjligt att uppleva välbefinnande. 

    Slutsats: Det framkommer i studiens resultat att de unga människorna som har obotlig cancer upplever både välbefinnande och att kroppen sviker dem under sjukdomstiden. De hanterade känslorna som den obotliga cancerdiagnosen medför på olika sätt. Det är därför viktigt att se varje människa som unik i vårdandet av cancerpatienter.

    Sjuksköterskors upplevelser av arbetsrelaterad stress i sjukhusmiljö: En kvalitativ intervjustudie2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Det finns olika faktorer som kan leda till arbetsrelaterad stress. Hög arbetsbelastning eller att det finns svårigheter i det sociala samspelet på arbetsplatsen. Det är arbetsgivarens skyldighet att förebygga arbetsrelaterad stress (Arbetsmiljöverket, 2016). Det kan till exempel beröra att öka bemanningen som i sin tur minskar pressen på arbetstagaren (ibid). Under de senaste åren har det varit rikligt med skriverier i media om massuppsägningar av sjuksköterskor inom landsting. Även rapporter om stora misstag inom vården har uppmärksammats (Westin, 2017). I Region Kronoberg, där studien är utförd har antalet uppsägningar bland sjuksköterskor ökat från 4,2 % år 2010, till 7,3 år 2016 (ibid). Avgångssamtal och enkäter som genomförts i olika landsting visar att det beror på arbetsbelastning, arbetsmiljö och stress (ibid). Det påverkar även patientvården när erfarna sjuksköterskor försvinner och vårdskadorna förväntas att öka (Westin, 2017), därmed riskeras patientsäkerheten.

    Skatteverkets nya styrning av beskattningsverksamheten: En kritisk analys av den södra regionen2017Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background: During the last year, the southern region of the Swedish Tax Agency's have made major changes in the way of controlling the incoming declarations to the agency. Earlier, each of the offices managed their own business and today the are managed jointly through the recently introduced network. Since the recently implemented management has not yet been analyzed, we, on behalf of the Swedish Tax Agency, were able to analyze how this change is experienced by employees in the southern region.

    Purpose: The purpose is to critically analyze how the change in management is experienced by employees and how these types of changes affect the value creation. This will eventually generate improvement proposals for the Swedish Tax Agency and other public activities.

    Method: In order to achieve the purpose of the essay, we conducted a case study which consists of interviews with persons within the Swedish Tax Agency's southern region who worked at the agency before and after the change in management.

    Result /Conclusion: We believe that the change in control will generate more efficient work in the incoming case flow, which will generate cost savings. After analyzing theoretical- and empirical parts we have also found that the Swedish Tax Agency has in general failed in their way of communicating with the employees during the course of change.

    Vd-rekrytering: Ur ett homosocialt reproduktionsperspektiv2017Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Introduction: Historically Sweden has had relatively few CEO-substitutions. In recent years the turnover on CEOs has increased, which has justified the question: “Who becomes the new CEO when a company is recruiting?” Recruitment is primarily influenced by internal players (the board, chairman of the board and former CEO) and the demographic characteristics (age, gender and nationality) of these actors tested in the study.

    Purpose: The purpose of the study is to explain how demographic characteristics, from the board, the chairman of the board and former CEO, affect the selection when recruiting a new CEO.

    Method: The study is based on existing theory and has a deduction method. Hypotheses are formulated on the basis of the theory of homosocial reproduction and based on the internal actors, the board, chairman of the board and former CEO. Quantitative method is applied and the extent is all companies in OMX Stockholm who had the CEO replaced in 2011-2016.

    Results and conclusion: The results of the survey show that it is the board and chairman of the board that influences the new CEO's nationality, which is in line with the assumptions of homosocial reproduction. The result showed no support for age and gender from any of the actors.

    VR Gaming - Hands On: The use and effects of bare hand gestures as an interaction method in multiplayer Virtual Reality Games2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The field of virtual reality (VR) is getting increasing attention from the scientific community and it is being portrayed by advertisements as the user interface (UI) of the future. This is a fair statement since the prior uses of VR that used to exist only in fiction movies and books are now widely available in many forms and settings to the public. One of the most interesting outcomes from this technological evolution is that now VR can be experienced through the use of a mobile phone and the addition of some inexpensive means typically in a form of a headset. The combination of the phone’s screen as attached to the headset creates a form of Head Mounted Display (HMD) which can be utilized in order for the user to be immersed within a virtual environment (VE). The argument here is that even if the means to get access to VR are cheap, this should not be the case with the experience as well. On the contrary, the low entry requirements in combination with a high quality experience are the basis for the medium's success and further adoption by the users. More specifically, the capability of utilizing a three dimensional space (3D) should not limit the medium’s use on just that but instead, this space should be used in order to offer immersive environments which make the user feel as if he is there.

       There are many factors that contribute to that result and significant progress has been made to some such as the quality of screen or other hardware parts that allow the user get immersed into the virtual scenery, however, little progress has been made towards the conceptual means that allow the user of better experiencing this VE. Most of the VR applications so far are specifically designed for a single user session. This creates an isolation of the user from any other type of communities which further increases the stigma of VR being a solitary experience. Another issue is the interaction method that is available to users in order to interact with the VE. The use of buttons in most of the available headsets is a counter intuitive method for a person to interact with an environment that wants to be called real. The technological advancements in the field of image processing have resulted in many new methods of interaction and multimodal manipulation within VE and it would be worthy of exploring their effects on the user experience (UX) when used as an interaction method.

       For these reasons, this thesis used the case of VR games as a setting to study how UX can be enhanced from its current state by introducing a bare hand gesture interaction method and expanding the VR setting in order to host two users in shared VE. Two individual studies were conducted where user feedback was collected in order to describe the effects of this approach in both a qualitative and quantitative manner. As results indicate, by utilizing gesture analysis on a headset equipped with a smartphone, it is possible to offer a natural and engaging solution for VR interaction capable of rich UXs while maintaining a low entry level for the end users. Finally, the addition of another player significantly affected the experience by influencing the emotional state of the participants in the game and further enforcing their feeling of presence within the VE.

    Att vara eller inte vara, det är hållbarhetsfrågan: En kvalitativ studie om klädbranschens arbete med CSR inom produktutveckling för att skapa en ekologisk produkt2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The purpose of this study is to examine what consideration is taken by fast fashion and functional fashion companies into the ecological perspective within CSR regarding the choice of the design and material during the product development process. The study also aims at examining how the CSR activities differ between the various companies.

    Method: The design of this study is based on a qualitative research method with a deductive approach. The empirical data was collected by interviewing respondents who hold knowledge within CSR, design, materials and product development. The theoretical framework consists of peer reviewed articles and books.

    Conclusion: The conclusion of this study shows that CSR is a complex term with multiple definitions that needs to be redefined so that companies can get a clear understanding of its meaning. The desire to work with CSR needs to come from top management to ensure a great impact and a successful integration across all departments within the company.

    The designers have a great impact on whether the garment becomes organic or not because of their involvement in the beginning of the product development process. A number of design strategies are presented on how to make a product more organic. The choice of material is also critical in developing organic products where new alternative materials and less harmful coatings have emerged. Finally, recycling is considered to be a future solution in reducing textile waste, however extended knowledge and technology are sought to succeed.

    Towards automated learning from software development issues: Analyzing open source project repositories using natural language processing and machine learning techniques2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis presents an in-depth investigation on the subject of how natural language processing and machine learning techniques can be utilized in order to perform a comprehensive analysis of programming issues found in different open source project repositories hosted on GitHub. The research is focused on examining issues gathered from a number of JavaScript repositories based on their user generated textual description. The primary goal of the study is to explore how natural language processing and machine learning methods can facilitate the process of identifying and categorizing distinct issue types. Furthermore, the research goes one step further and investigates how these same techniques can support users in searching for potential solutions to these issues.

    For this purpose, an initial proof-of-concept implementation is developed, which collects over 30 000 JavaScript issues from over 100 GitHub repositories. Then, the system extracts the titles of the issues, cleans and processes the data, before supplying it to an unsupervised clustering model which tries to uncover any discernible similarities and patterns within the examined dataset. What is more, the main system is supplemented by a dedicated web application prototype, which enables users to utilize the underlying machine learning model in order to find solutions to their programming related issues.

    Furthermore, the developed implementation is meticulously evaluated through a number of measures. First of all, the trained clustering model is assessed by two independent groups of external reviewers - one group of fellow researchers and another group of practitioners in the software industry, so as to determine whether the resulting categories contain distinct types of issues. Moreover, in order to find out if the system can facilitate the search for issue solutions, the web application prototype is tested in a series of user sessions with participants who are not only representative of the main target group which can benefit most from such a system, but who also have a mixture of both practical and theoretical backgrounds.

    The results of this research demonstrate that the proposed solution can effectively categorize issues according to their type, solely based on the user generated free-text title. This provides strong evidence that natural language processing and machine learning techniques can be utilized for analyzing issues and automating the overall learning process. However, the study was unable to conclusively determine whether these same methods can aid the search for issue solutions. Nevertheless, the thesis provides a detailed account of how this problem was addressed and can therefore serve as the basis for future research.

    Spelifiera för att träna mera: En studie som undersöker ifall en träningsapplikation med inslag av digital personlig tränare och spelifiering kan öka motivation under träning2017Student paper other, 180 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study is to research whether an exercise application

    with a feature of gamification and personal trainer may increase motivation

    during exercise, as well as what features are desired in such an application.

    Training is something that is important for a person's well-being, thus the

    idea of the application is to get more people involved in physical activity.

    To understand what motivates people overall but also specifically to work

    out, several theories have been studied, such as achievement goal theory

    and the transtheoretical model of change. Seven interviews were conducted

    to find out what features were desired. They gave a variety of suggestions

    on features, including tips on new exercises and visual instructions. With

    the help of collected data from the interviews and examination of theories, a

    prototype was developed. In the prototype gamification has been

    implemented with game elements like levels and badges with the hope that

    gamification will help change behavior and strengthen motivation and

    commitment. In order to find out if the developed prototype could increase

    motivation during exercise, a number of user tests were conducted. In the

    test, they first had to fill in a questionnaire where they, among other things,

    had to indicate their attitude towards exercise. The participants were then

    asked to perform two identical workouts. The first only included a paper

    with instructions for the planned workout. The second workout was

    performed together with the prototype. During the two workouts,

    quantitative data was collected through Emotiv which measure the brain's

    electrical activity (EEG). Once the training sessions were completed,

    participants were asked to take part in an interview. These included

    questions about level of motivation, comparing one session to the other. By

    analyzing data from Emotiv, it was by no means possible to see that the

    participants became more motivated while using the prototype. However, it

    was clear from the interviews that participants felt more motivated and

    found it more fun when they were training with the prototype. Data from

    these interviews will form the basis for the final result. Gamification got a

    positive response from the participants during the interview when a couple

    of people thought that the game elements could definitely contribute to

    increased motivation. All participants during the user test stated that they

    were working out for their own sake, which can be seen as mastery-approach goals according to achievement goal theory. However, it is

    difficult to assert that the results in this study are absolutely certain as

    participants did not have enough time to interact with the prototype.

    Titel: Prestationsmätning i en global koncern - En fallstudie på ITAB Shop Concept Nässjö AB

    Författare: Sofie Engelbrekt and Susanna SvenssonExaminator: Fredrik KarlssonHandledare: Elin Funck

    Bakgrund: Globala organisationer står inför utmaningen att lyckas behålla flexibilitet och anpassning till lokala förutsättningar. Samtidigt som de behöver ena och hålla samman olika bolag till en enhet för att kunna nå globala konkurrensfördelar. Ett dotterbolag inom en global koncern behöver integrera koncernens strategier och mål, samtidigt som de anpassar sig utefter sin verksamhets förutsättningar. Prestationsmätningssystem kan hjälpa företag att styra verksamheten i rätt riktning. Alla organisationer har dock olika förutsättningar och strukturer, vilket gör att “ett bästa sätt” inte går att finna för hur ett prestationsmätningssystem bör utformas.

    Syfte: Syftet med studien är att utforma ett väl fungerande prestationsmätningssystem för ITAB Nässjö, genom att utvärdera den nuvarande prestationsmätning och identifiera förbättringsmöjligheter. Utvärderingen kommer ligga till grund för att utforma ett förbättrat prestationsmätningssystem som fångar lokala förutsättningar och fångar helheten i verksamheten såväl som integrationen till koncernen. Studien bidrar med kunskap inom prestationsmätning kopplat till ett företags lokala förutsättningar och komplexiteten i att integrera och koordinera en stor global koncern.

    Metod: För att uppfylla studiens syfte behövs god insyn och djupgående information om ITAB Nässjö, vilket gör fallstudie till en lämplig metod. Datainsamling har framförallt skett genom semistrukturerade intervjuer, företagsdokument samt årsredovisningar.

    Slutsats: Studien identifierar ITAB Nässjös kritiska framgångsfaktorer, utefter vad som är strategiskt viktigt på lång sikt. Baserat på detta har förbättringsmöjligheter i den befintliga prestationsmätningen identifierats, vilket resulterar i ett förslag på hur ett förbättrat prestationsmätningssystem kan se ut som är utformat efter lokala förutsättningar, fångar helheten i verksamheten och bättre integrerar koncernens styrning.

    SÄLJARENS MOTIVATION: En fallstudie av säljares upplevda motivation i förhållande till dess incitamentsprogram2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning

    Bakgrund: Incitament är vedertaget inom försäljningsorganisationer och används för att motivera och styra medarbetares aktiviteter mot företagets mål. Problemet är att detta utgör ett komplext område, dels att forskningen är motstridig inom vilken typ av incitament som motiverar, dels komplexiteten inom motivationsområdets forskning som belyser stora individuella skillnader. För att incitament ska vara effektiva bör de träffa rätt inom båda områdena. Intresset för denna studie motiveras av att tidigare forskning främst utgår från ett företagsperspektiv, medan denna studie tar medarbetarens perspektiv.

    Syfte: Syftet med studien är att identifiera och analysera medarbetares motivationsaspekter i relation till ledningens styrmedel.

    Metod: Studien är kvalitativ och har en abduktiv ansats och utgörs av en tvåfalls fallstudiedesign. Studien genomfördes med hjälp av semistrukturerade intervjuer, sju säljare utgjorde studiens respondenter. Empirin analyserades genom kodning och meningskategorisering.

    Resultat: Att bli monetärt belönad för sin prestation ansåg respondenterna som självklart men samtidigt framfördes det kritik mot hur incitamentssystemet var utformat. Icke monetära incitament som uppskattades var frihet och utvecklingsmöjligheter. Som demotiverande beskrevs inslag av mikromanagement från chef vid uteblivna resultat.

    Slutsatser: Studien visar på en enighet att provision är ett viktigt inslag för att utföra arbetet men i sig inte huvudsakligen motiverande. Vikten av frihet och utvecklingsmöjligheter framhölls som något eftertraktat och motiverande. De individuella skillnaderna respondenterna emellan påvisar att incitament för att vara effektiva bör vara individanpassade.

    Benchmarking: Den nya budgeten2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Titel: Benchmarking - The new budget

    Background: Budget is a widely used management tool which has been criticized during recent years. The critique implies that a budget is too rigid in a world with swift changes and that management tools are needed which meet the playing conditions of today. Several companies have chosen to implement a model that goes beyond budgeting. This is a consequence of the fact that they believe a budget cannot face the uncertainty that the market possesses. A popular tool which is able to meet the struggles that companies face is benchmarking. By comparing and learning within the organization as well as exchanging knowledge with other companies, these actors are trying to reach best practice.

    Purpose: The purpose with our study is to create a theoretical framework of how benchmarking can substitute the purpose of budgeting. The next step is to use the framework to compare internal benchmarking within different levels in two companies. Our study has the aim to contribute with knowledge of how benchmarking can substitute budgeting. This study also aims to address how different levels, top and ground level, interpret benchmarking within the company.

    Theoretical framework: This study’s theoretical framework consists of budgeting, beyond budgeting and management tools with the aim of finding a substitute for budget.The focus is on benchmarking and consists of the purpose, the process, benchlearning, internal and external benchmarking as well as advantages and disadvantages to create a broad understanding of the concept.

    Method: We conduct a comparison study of two companies practicing beyond budgeting. The companies are, Handelsbanken AB and Ahlsell AB. In our study, we have applied a qualitative approach to collect and analyse the empirical material.

    Findings: The study shows that according to theory, benchmarking is able to substitute all the purposes of budget except for two. These two purposes, planning and resource allocation, could be substituted by the complement rolling forecasts. Benchmarking could, for this reason, not on its own substitute the budget, but needs to be complemented in order to form a complete substitute for budget. This theory is confirmed by the empirical material gathered from two companies, Ahlsell and Handelsbanken. In comparison between the different levels within the companies, a conclusion is made that in contrast to earlier suggestions, benchmarking is not implemented too generally or only on a centralized basis. It is used on different levels within the companies and the view of benchmarking is more or less uniform between these levels.

    Intern kommunikationsstrategi i bemanningsföretag: En kvalitativ studie om hur konsulter och konsultchef uppfattar att kommunicera genom digitala verksamhetsstöd2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Studien är genomförd i en fallverksamhet som är verksam inom bemanningsbranschen. Studien är ett examensarbete utfört av studenter på Linnéuniversitetets program för informationslogistik under vårterminen 2017. Den här studien har undersökt hur konsulter uppfattar att kommunicera via ett digitalt verksamhetsstöd med konsultchef. Tidigare forskningen som genomförts om kommunikation på distans har genomförts i ordinarie verksamheter och inte specifikt på bemanningsföretag som är en annan typ av organisation. Tidigare forskning som genomförts i bemanningsföretag har inte fokuserat på kommunikation på distans utan mer om vilka problem som uppstår mellan konsult och konsultchef. En avsaknad i den tidigare forskningen har identifierats där kommunikation på distans i bemanningsföretag inte studerats närmare. Teorierna som har använts i den här studien är Tecknologiacceptansmodellen (TAM), Media richness theory (MRT) och Media synchronicity theory (MST). Teorierna används i studien för att belysa användning av system, kommunikationskanalers förmåga att överföra information samt kommunikationskanalers förmåga att synkronisera sändare och mottagare. Studiens metod har varit kvalitativ och explorativ där observation och semistrukturerade intervjuer använts för att samla nyanserad data om studiens problem. Studien visar att konsulter har en positiv inställning till digitala verksamhetsstöd när arbetsrelaterade frågor kommuniceras och att användningen av systemet är anpassat efter konsulternas och konsultchefens kontext. Konsulterna menar också att ett digitalt verksamhetsstöd inte ska upplevas som extra arbete vilket kan påverka deras användning av systemet. Konsulterna ställer sig kritiska till att använda ett digitalt verksamhetsstöd när något privat behöver kommuniceras med konsultchefen eller om något problem uppstått och en snabb lösning efterfrågas.

    Patienters uppfattning av information innan anti-VEGF behandling2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Age-related macular degeneration (AMD) affects primarily older people. The vision is rapidly deteriorating in the central parts. Previous studies have identified inadequate information to cause anxiety for treatment. In order to develop the information, it is important to know how the information is perceived.

    Purpose: The purpose of the study is to describe patient perceptions of the information given prior to anti-VEGF treatment.

    Method: Phenomenographic approach has been used as a method of study. The essential of Phenomenography is to find the variation of perceptions within a group and describe the phenomenon in description categories. Deep interview was used as a collection method and nine patients were interviewed about the information and experience of the injections.

    Result: The result shows three description categories. The first category is: Unclearness in the information that describes the informant’s way to view the information. The second category describes how to trust the healthcare professionals. The third and last description category is to feel anxiety which describes thoughts of others, to hygiene and to pain.

    Conclusion: The study has shown that patients who do not receive the correct custom information feel anxiety before treatment. Patients often have many questions about the diagnosis and how the treatment will be addressed. They seek answers to questions by either using the internet or contacting the eye clinic. A more individually adapted verbal information supplemented with good written / digital information could reduce the concerns of the patients.

    Oro, ångest och smärta i samband med intravitreala injektioner: En beskrivande och korrelerande enkätstudie2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Intravitreala injektioner där läkemedel administreras till ögats glaskropp är en välanvänd behandlingsmetod. Det förekommer att patienter känner både oro och ångest inför- samt smärta i samband med injektionen.

    Syfte: Syftet var att beskriva förekomsten av oro samt ångest före och smärta under intravitreala injektioner, samt att fastställa sambandet mellan upplevd oro, ångest och smärta.

    Metod: En kvantitativ enkätstudie genomfördes på S:t Eriks Ögonsjukhus i Stockholm. Oro och ångest mättes innan behandlingen och smärta efter behandlingen med validerade mätinstrument.

    Resultat: Den självskattade oron, ångesten och smärtan vid de intravitreala injektionerna var generellt låg. Medelvärdet för självskattad oro var 2,7 (SD=2,7), medelvärdet för självskattad ångest var 10,4 (SD=3,6) och medelvärdet för självskattad smärta var 2,3 (SD=2,1). Resultatet visade att det fanns ett bivariat signifikant samband mellan oro och ångest samt smärta vid injektionen. Resultatet visade även att numerisk skattningsskala (NRS) för oro korrelerade starkare med självskattad smärta än ångesten enligt State Trait Anxiety Inventory (STAI-S).

    Slutsats: I framtiden kan interventioner utvecklas för att minska patientens oro och ångest innan injektionen, vilket kan förbättra upplevelsen av injektionerna och minska upplevelsen av smärta. Att undersöka upplevelsen av oro vid intravitreala injektioner med NRS skalan skulle kliniskt kunna implementeras inom ögonsjukvården.

    Comparative study on user's perception of privacy issues on Facebook: Young adults vs. adults in Sweden2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Facebook is a social network that has more than 1.5 billion active members. With the term ‘active’ we mean users who sign in at least once every day on Facebook. Sharing personal information has become a popular activity within the development of all the social networks. Facebook, for instance, contains settings for privacy that allow the user to adjust how "far" the user wants to share his/her own personal information. The problem comes when this can lead to private issues and concerns. The aim of this research was to study the privacy issues perceptions of people within two different ranges of ages, under and over 35 years old. Firstly, we analysed how much people know about privacy on Facebook, and then we tried to understand if there are similarities or differences between those two groups. We thought it would be interesting to know the current state of this phenomena and there was no much research done in Sweden about it. The research was conducted using the mixed method because we wanted to get more global responses from a larger number of respondents in a survey and we wanted to get more detailed answers from an open questionnaire through interviews. We intended to know how is the general knowledge about privacy on Facebook among Swedes. The results showed that people who belonged to the adults group took slightly more care on their privacy than the young-adults group. Also, we discovered that, in general, people are more informed about the risks coming from privacy leaks than a few years ago.

    Är STCW-kraven i STCW A-III/1 uppfyllda i kursplanerna?: En litteraturstudie om Sjöfartshögskolan i Kalmars kursplaner och STCW-koden2017Independent thesis Basic level (professional degree), 180 HE creditsStudent thesis
    Abstract [sv]

    Huvudfrågeställningen i studien var om Sjöfartshögskolan i Kalmar kursplaner uppfyller de krav som ställs i STCW del A-III/1 på utbildningsprogrammen för sjöingenjörer. Syftet med arbetet var att verifiera Sjöfartshögskolan i Kalmars kursplaners uppfyllelse av STCW-kraven enligt del A-III/1 för sjöingenjörer. Metoden som användes var en kvalitativ litteraturstudie där de i STCW uppställda kraven enligt del A-III/1 studerades och jämfördes med kursplanerna inom utbildningsprogrammet för sjöingenjörer på Sjöfartshögskolan i Kalmar.  Resultatet som framkom var att 72 % av kraven i A-III/1 var uppfyllda i kursplanerna för Sjöingenjörsprogrammet i Kalmar. Min rekommendation är att kursplanerna ses över och justeras för att bättre stämma överens med STCW-kraven, för att säkerhetsställa att kvaliteten på utbildningen är hög och konstant.

    Cirkulär ekonomi: Hur kan klädbranschen styra kunder till att vilja bidra?2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Klädbranschens normativa resursflöden är linjära, vilket innebär att naturresurser utvinns för att kunna tillverka produkter som sedan kastas när dess livslängd är förbrukad. Att ständigt behöva utvinna nya naturresurser är inte bara plågsamt för vår miljö utan dessutom väldigt kostsamt för företagen. Många ser en cirkulär ekonomi som lösningen på hur vi ska kunna behålla vårt konsumtionssamhälle utan att förstöra vår planet. Flera klädföretag tillämpar redan cirkulära processer i form av exempelvis klädinsamling där de tar emot gamla kläder för kunna återanvända materialet men upplever att det finns ett motstånd från kunderna till att bidra. Denna kandidatuppsats undersöker genom en kvantitativ studie vilka faktorer som kan leda till att deltagandet från kunderna ökar. Studien finner stöd för att hur pass informerade kunderna är samt kundens sociala omgivning har betydelse för kundens vilja att återlämna gamla kläder.

    Analys och jämförelse av två pilotanläggningar med olika sammansättning av membran: Vid rening av processvatten från industri2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Vattentillgången på Öland har under en lång tid varit mycket ansträngd och har kommit till en punkt då det inte längre är hållbart. För att nå en mer långsiktig lösning planerar Mörbylånga kommun med hjälp av Norconsult att bygga ett vattenreningsverk. Detta kommer att rena bräckt vatten ifrån Kalmarsund samt processvatten ifrån Guldfågeln AB, som tillsammans kommer att fungera som ett komplement till det redan befintliga sötvattnet.

    Två pilotanläggningar som renar processvatten ifrån en industri, genom ultrafilter kombinerat med omvänd osmos, har utvärderats. En metod för att sammanställa de kostsamma driftparametrarna elförbrukning, förbrukning av kemikalier samt underhållsarbete vid drift och membranens inköpskostnad genom en LCC har tagits fram. Denna metod ger en ungefärlig totalkostnad per kubikmeter av det renade vattnet. Även vattenkvaliteten på ingående råvatten, vattnet mellan membranen samt det utgående vattnet har analyserats. Detta för att undersöka att processerna fungerar som den ska, samt ge en indikation på vilka mineraler som kommer att behöva tillsättas i efterhand.

    Pilot B blir ca fem kronor dyrare per kubikmeter jämfört med Pilot A. De totala kostnaderna, 9.70 – 10.79 kr/m3 för Pilot A och 15.19 – 15.28 kr/m3 för Pilot B, kan jämföras med den nuvarande kostnaden för en kubikmeter vatten i Mörbylånga, 15 kr/m3, samt den kostnad kommunen betalade sommaren 2016 för att frakta vatten i tankbilar, 70 kr/m3.

    Improved lifetime of a rubber spring in an articulated hauler through product development2017Independent thesis Advanced level (degree of Master (One Year)), 40 credits / 60 HE creditsStudent thesis
    Abstract [en]

    Dampening systems are important in heavy vehicles utilized in rough terrains, with purpose to reduce shocks and vibrations with negative influences on the vehicle and, more importantly, on the operator of the vehicle. During the years the heavy vehicles require sturdier construction parts, due to demands on higher load capacity, where the easy solution to scale up the construction parts is not always applicable for dampening systems with nonlinear behavior. Hence, the sturdiness in the design of these dampening systems requires improvement. In this thesis the design of the rubber spring used as rubber spring in Volvo’s articulated hauler A40G is treated. The aim of this thesis is to find alternative design solutions on the rubber spring, improving its lifetime. The usual failure of these rubber springs is crack propagation in the rubber body. In the method of this thesis, alternative design solution are generated in concepts though brain storming, which are adjusted to achieve the desired behavior of the rubber spring through calculations and tested in performance through simulations in Abaqus. From analyzing the generated data, it is concluded that among the tested design solutions, a combination of fewer plates and shaping the plates as thin bowls, results in highest potential increase in lifetime.

    Energisimulering Av Äldre Flerbostadshus: En simulering av förbättringspotential i äldrefastigheter med hjälp av solceller, värmepumpar och tilläggsisolering.2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I detta examenarbete har olika energieffektiviseringsåtgärder jämförts på två flerbostadshus i Ljungby kommun vars namn är Halfdan och Arngrim. I det första alternativet modulerades de befintliga byggnaderna för att kunna se dess totala energianvändning. Det andra alternativet består av att tilläggsisolera vindsvåningen samt byte av fönster och dörrar. Dessa åtgärder bidrar med en besparing på ca. 90 000 kWh/år Halfdan samt 55 000 kWh/år Arngrim. I det tredje alternativet installeras en frånluftsvärmepump samt en solcellsanläggning i vardera byggnad. Detta resulterar i en energibesparing på ca. 127 000 kWh/år i Halfdan samt 101 000 kWh/år i Arngrim.

     

    Fastigheterna har simulerats i Energiberäkningar och VIP+ Energy, där resultatet påvisar att frånluftsvärmepumpen bidrar med den största energibesparingen i förhållande till det andra alternativet.

    Energieffektiva klimatskal i flerbostadshus: Tillämpning av nära-nollenergikrav2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Hårdare energidirektiv från EU gällande energianvändning i byggnader har resulterat i Boverkets framtagande av Sveriges kommande nära-nollenergilagstiftning. Den kommande lagstiftningen kommer ur energisynpunkt innebära ett paradigmskifte för hur man projekterar och bygger nya byggnader i Sverige. I samarbete med WSP Sverige AB har detta arbete huvudsakligen undersökt potentialen att klara av denna omställning, genom att fokusera på minimering av energiförluster från transmission i en byggnads klimatskal. Arbetet innehåller en omprojektering av en specifik byggnads klimatskal. Vid framtagandet av detta klimatskal har olika konstruktionsalternativ simulerats och analyserats för att på ett kostnadseffektivt sätt avgöra den ambitionsnivå som krävs för att uppnå kraven i den kommande lagstiftningen. Utöver Boverkets kommande lagstiftning har även möjligheten att klara av viktade krav från miljöclassifieringssystemet Miljöbyggnad analyserats.

    Energieffektivisering av flerbostadshus från miljonprogrammet2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I Sverige kvarstår cirka 650 000 bostäder i flerbostadshus uppförda under miljonprogrammet. Dessa byggnaders drift kräver stora mängder energi. Byggnaderna från den här eran står dessutom inom en snar framtid inför stora renoveringsbehov. I sambad med renovering är det därför viktigt att tänka energieffektivt och vidta extra åtgärder för att sänka dess energiförbrukning. I studien framgår att det finns goda möjligheter att sänka energianvändningen i dessa byggnader med åtgärder som kan vidtas i samband med renovering.

    Modulhustillverkning i fabrik: Standardisering i tillverkningsindustrin2017Independent thesis Basic level (professional degree), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [sv]

    Studien undersöker hur ett byggföretag som arbetar med prefabricering kan standardisera dess produktionsprocess och stödaktiviteter. Studien försöker även genom reducering eller eliminering av slöseri förbättra processcykel effektiviteteten. Studien genomförs på ett fallföretag. Fallföretaget är nystartat och tillverkar modulhus och element. Fallföretaget saknar ett standardiserat produktionsflöde och arbetsuppgifter. Det råder också kommunikationsbrister då majoriteten av operatörerna är första generationens invandrare från olika länder. Studien kommer genom mätningar och observationer fram till att en anläggningsplanering med ett standardiserat produktionsflöde och fasta arbetsstationer kan minska slöseri och för att förbättra processcykel effektiviteten hos fallföretaget
