    Exploring a New Way of Food Inventory Management in Households Using Modern Technologies to Reduce Food Waste2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Food waste is becoming an increasing threat to the environment and the economy. Estimates indicate that annually, a third of the food produced around the world ends up being wasted. Only one-fourth of that food is enough to take nearly a billion people out of starvation. Food waste is especially higher in more developed countries, including most of the states in the European Union and the USA. Sector-wise, food is being lost from field to fork, with households topping the charts. Overbuying, not knowing what already is in the fridge, unaware of the food until it eventually expires, are among the most common reasons that contribute to the food waste. The potential prevention of such massive waste could significantly reduce the amount of greenhouse gas emissions around the world and help the economy of the households including all the parties involved in food production, distributing and retailing.

    On the other hand, technology has progressed in very rapid steps. The advancement of AI, ML, IoT, and voice-enabled devices has revolutionized many industries and has made us more efficient as human beings. Unfortunately, these advancements haven't yet had any significant impact in assisting families with their food choices and in preventing them from overbuying and throwing food away. Most of the proposed solutions addressing this issue, do not get integrated into everyday life. That is because they require a lot of manual input, rely entirely on mobile phones, do not show immediate results to keep users motivated, and on top of all, for the sole fact that modern lives are quite complex, and although an important issue, food waste is not an everyday cause of concern of an average person.

    This thesis takes into account all of the shortcomings of the previous works and aims to create a more sustainable solution by exploring new ways of food inventory management in the households by automating the process so that users don't have to manually enter the data themselves. The proposed solution consists of a device that should be easily mounted into any fridge and acts as an interface between users and their food inventory. The device contains a bar-code scanner for the item input and a back-end that is capable of recognizing the item and can in return show user-friendly and valuable information such as the approximate price of the item, the approximate due date etc. and notifies users when an item is about to expire so that they can take appropriate actions.

    7 out of 9 participants in the final conceptual design study said they would use this solution in their homes. The rest of the results from the designed test cases indicate a clear excitement and interest in participants and a willingness to see the prototype in the finished state, all the comments and insights together with the future work and how the feedback will be used into the next iteration are part of the final discussion of this thesis.

    Homelessness and Social Exclusion in Two Swedish Cities2019In: European Journal of Homelessness, ISSN 2030-2762, Vol. 13, no 1, p. 31-58Article in journal (Refereed)
    Abstract [en]

    The aim of this study is to describe the living conditions of homeless people in the cities of Gothenburg and Karlskrona in Sweden and to analyse their level of social inclusion and social exclusion. The empirical basis of the study was interview responses from 1 148 individuals in connection with initial contact with municipal housing programmes. The study clarifies that people in these programmes are a heterogeneous group in terms of gender, background and current living situation. A majority of the homeless people are living in difficult conditions and are in extremely exposed positions. Three different groups emerged in the analysis of the study population: individuals who are socially included (15%), marginalised (65%) or socially excluded (19%). The article also discusses the various groups’ discrete needs and their implications for preventive as well as more interventional actions on the political and practical levels.

    Correlates of soccer-specific change of direction speed and reactive agility2018In: Presented at 6th NSCA International Conference, 2018Conference paper (Refereed)
    Abstract [en]

    INTRODUCTION: Definition of Agility is based on a model that separates agility in two components, change of direction speed and perceptual and decision making processes. Based on that, two independent types of agility-performances have been identified, including change of direction speed (CODS) and reactive agility (RAG). In addition, agility is known to be a significant determinant of success in soccer due to a high perceptual and decision making skills as well as change of direction demands in soccer. CODS and RAG are generally considered as independent qualities which further suggests that they should be tested and developed separately. However, it remains unclear whether soccer-specific CODS and RAG should be regarded as disparate qualities. METHODS: Twenty young male soccer players (17.0 ± 0.9 years; 1.81 ± 0.03 cm; 70.05 ± 7.41 kg), who participated at the highest level of competition in Sweden at their age, twice reported to the lab to perform soccer specific CODS and RAG tests. First session was familiarization session while the second which consisted of actual CODS and RAG testing took place 72h later. Both CODS and RAG tests consisted of stop-and-go movement patterns which are very common in a soccer game. In addition, both tests included change of direction with the simple ball kicking template. This ball kicking template was invented to mimic defensive soccer skills of stopping the opponent’s first touch with the ball and pass interception. Participants had advanced knowledge of the movement pattern during CODS while they had to react on a visual stimulus that was followed up by change of direction during RAG. RAG testing was done throughout three different protocols (RAG1, RAG2, and RAG3) with CODS being performed once. Both tests consisted of five trials with the 10-15 seconds of rest periods between attempts and 3 minutes of rest between the protocols in RAG. Participants performed all protocols in a random order and after reliability analysis, the best performance was retained as the final result of each participant. Measurements were performed by a hardware device system based on an ATMEL micro-controller (ATMEL Corp, San Jose, CA, USA) as the core of the system. A photoelectric infrared sensor (E18-D80NK) was used as an external time triggering input, and LEDs were used as controlled outputs. Pearson’s product-moment correlation coefficients (r) were calculated to reveal the relationships between the tests. RESULTS: The CODS was significantly, but moderately correlated with the RAG1 (r =.50, p <.05), RAG2 (r=.56, p<.05), and RAG3 (r=.63, p<0.01) RAG tests. DISCUSSION: Although significant relationships have been observed, the results showed that the CODS test and RAG tests share only 25, 31 and 39% of the common variance which suggests them being independent qualities. Practitioners in soccer should be looking at these qualities in a unique way with the aim to test and develop them separately.

    Att skapa ett attraktivt stadsrum2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Städer i Sverige utvecklas ständigt och samhällsplanerarna ställs inför nya utmaningar. Utvecklingen av dagens moderna städer formas av utmaningen att uppnå EU:s hållbarhetsprinciper. Detta ska göras genom att tillfredsställa dagens behov utan att äventyra kommande generationers möjlighet att tillfredsställa sina. En stad som anses vara hållbar kännetecknas av att planeringen och byggandet sker efter ett långsiktigt mål för ett beständigt samhälle. Det hållbara samhället präglas av trivsamma miljöer som skapar mänsklig närvaro. För att detta skall uppnås måste stadsrummet upplevas som attraktivt. Det attraktiva värdet har en betydande roll i arbetet och strävan i skapandet av hållbara städer. I följande rapport undersöks vilka arkitektoniska attribut som anses vara attraktiva i stadsmiljöer samt vilka attribut som upplevs ha en positiv inverkan på människan. Undersökningen baseras på datainsamling från en enkät, intervjuer och platsobservationer. Resultatet redovisar information om vilka arkitektoniska kvalitéer som människan anser som attraktiva, de utmaningar och svårigheter som uppstår i ett stadsutvecklingsprojekt samt vilka kvalitéer som kännetecknar en stads identitet. Den insamlade informationen användes som grund för framtagandet av ett visuellt förslag av utveckling för Brädholmen i Oskarshamns inre hamn. Ett attraktivt stadsrum innefattas av relationen mellan byggnadernas variation, originalitet, småskalighet, kulörrikedom och historiska komponenter. Stadsrummet bör kännetecknas av tre samverkande faktorer, byggnaders estetiska utförande, mänsklig rörelse och landskapets kvalitéer.

    Abstraktionsnivå och grammatisk utveckling i L2-elevers texter: En analys utifrån systemiskt-funktionellt perspektiv och processbarhetsteorin2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den här studiens syfte var att relatera elevers språkliga abstraktionsgrad med deras grammatiska nivå enligt Processbarhetsteorin (PT). Med utgångspunkt i systemisk-funktionell grammatik (SFG) analyserades abstraktionsgrad i form av informationstunga ord samt vilka processtyper eleverna använde. För att få ett ytterligare perspektiv på abstraktionsgrad vägdes även ett kvantitativt kognitiv-psykologiskt mått, konkretionsvärden, in i analysen. Materialet som analyserades bestod av 18 argumenterande texter, skrivna av elever vid ett språkintroduktionsprogram. Studien visade på en koppling mellan elevers grammatiska nivå enligt processbarhetsteorin och hur abstrakt språk de använde. PT-nivå varierade mellan nivå 3, 4 och 5 och elever som hade kommit längre grammatiskt, det vill säga PT-nivå 4 och 5, använde flerrelationella processer och till viss del även fler informationstunga ord.. . Alltså var språket hos dessa elever, enligt både den SFG-baserade analysen och den databas som användes, mer abstrakt.

    Concept of Interactive Video in Job Application: A qualitative research that tests the concept of interactive video and job seekers’ ability creating interactive video resumes.2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Interactive video seems to currently be an unpopular field of research. Video resumes however is an increasing trend when applying for jobs and sending out resumes. During this thesis, employers finds interactive video as a new, fun and exciting way of interacting with a resume that simplifies the recruitment process. Also, job seekers find creating interactive video as resumes as an extra nudge in to a company and a better way of marketing themselves for employers. However, conflict occurs between employers and job seekers regarding an interactive video resume. As it simplifies the recruitment process, job seekers have to put down more work when creating an interactive video resume while applying for a job.

    It is shown in this thesis that there are factors that should be investigated, for instance a platform aimed at interactive video resumes seems not have been developed yet as well as what interactive features an interactive video resume should contain. Job seekers find it difficult if creating such resumes took too long, being unaware of how to display interactive visual elements and which aspects to talk about while recording themselves.

    This thesis explores the possibility of employers and former recruitment personnel using an interactive video resume as well as job seekers’ ability of creating an interactive video. The main aims of this thesis are to find guidelines of what an interactive video resume mainly should contain and what job seekers thinks of creating and using an interactive video when applying for jobs.

    Information and Memory for Future Decision-Making – Radioactive Waste and Beyond: Proceedings of the Stockholm workshop 21–23 May 20192019Conference proceedings (editor) (Other academic)
    Abstract [en]

    These proceedings document a workshop on the the issue of records, knowledge and memory (RK&M) preservation over centuries and millennia, which is a topic of increasing concern in Sweden as well as in other countries. The participants were mostly from Sweden and represented governmental agencies, universities, local communities, regulators, industry, policy makers, civil society organizations and the press. It was the first time in Sweden that such a wide group of experts could address the issue of preserving RK&M in order to enable future society to make knowledgeable decisions concerning environmental legacies inherited from the past.

    The workshop benefitted from the expertise and active involvement of all participants and the relevance of so wide a set of viewpoints and experiences. The international participants provided an overview of thinking and progress from outside Sweden. The resulting chart of principles and practical goals as well as the workshop proceedings provide an important foundation for developing new avenues for cooperation and strengthening and extending current practices in RK&M preservation. This should advance both the field of radioactive waste management and the management of other long-term legacies in the context of sustainable development for the benefit of future generations.

    Accuracy and reliability of a free mobile HRV application in measurement of heart rate variability2019In: Journal of Human Sport and Exercise, ISSN 1988-5202, E-ISSN 1988-5202, Vol. 14, no 4proc, p. S578-583Article in journal (Refereed)
    Abstract [en]

    Background: This study aimed to investigate the accuracy and reliability of a free mobile heart rate variability (HRV) application in measuring HRV. Methods: Twelve females and 12 males underwent five-minute simultaneous HRV recording from electrocardiogram (ECG) and chest strap connected to a free mobile HRV application (HRVapp) in a supine position. HRV data from ECG and HRVapp were used to examine accuracy and reliability via relative error and intraclass correlation coefficient respectively. Results: The natural log of the square root of the mean of the sum of the squares of differences between adjacent normal to normal intervals (lnRMSSD) exhibited accuracy and high reliability in HRVapp. Conclusion: lnRMSSD in HRVapp can serve as an alternative, low-cost technology for measurement of autonomic activity.

    Characterization of dredged sediments: a first guide to define potentially valuable compounds - the case of Malmfjärden Bay, Sweden2019In: Advances in Geosciences, ISSN 1680-7340, E-ISSN 1680-7359, Vol. 49, p. 137-147Article in journal (Refereed)
    Abstract [en]

    Millions of tons of bottom sediments are dredged annually all over the world. Ports and bays need to extract the sediments to guarantee the navigation levels or remediate the aquatic ecosystem. The removed material is commonly disposed of in open oceans or landfills. These disposal methods are not in line with circular-economy goals and additionally are unsuitable due to their legal and environmental compatibility. Recovery of valuables represents a way to eliminate dumping and contributes towards the sustainable extraction of secondary raw materials. Nevertheless, the recovery varies on a case-by-case basis and depends on the sediment components. Therefore, the first step is to analyse and identify the sediment composition and properties. Malmfjärden is a shallow semi-enclosed bay located in Kalmar, Sweden. Dredging of sediments is required to recuperate the water level. This study focuses on characterizing the sediments, pore water and surface water from the bay to uncover possible sediment recovery paths and define the baseline of contamination in the water body. The results showed that the bay had high amounts of nitrogen (170–450 µg L−1 ), leading to eutrophication problems. The sediments mainly comprised small size particle material (silt, clay and sand proportions of 62 %–79 %, 14 %–20 %, 7 %–17 %, respectively) and had a medium–high level of nitrogen (7400–11 000 mg kg−1 ). Additionally, the sediments had little presence of organic pollutants and low–medium concentration of metals or metalloids. The characterization of the sediments displays a potential use in less sensitive lands such as in industrial and commercial areas where the sediments can be employed as construction material or as plant-growing substrate (for ornamental gardens or vegetation beside roads).

    Numerical simulation of moisture driven fracture in mechanical timber connection using XFEM2017In: CompWood 2017 ECCOMAS Thematic Conference on Computational Methods in Wood Mechanics – from Material Properties to Timber Structures, Vienna, Austria, June 7-9, 2017, TuVerlag , 2017, p. 25-25Conference paper (Refereed)
    Abstract [en]

    Structural timber and glulam elements are an appealing alternative when it comes to choosing between structural elements as load bearing parts in e.g. halls, arenas and residential buildings. The wooden material is relatively strong in respect to its weight and its stiffness is sufficient enough to allow its use in a wide range of applications. However, there are also challenges associated with handling the material, one of which is the dimensional instability associated with moisture changes. The effect of climate variations on moisture induced deformations, stresses and failure in timber structures has already been addressed by several researchers, see e.g. [1] and [2]. A numerical model developed in the finite element package Abaqus is proposed herein to simulate crack propagation caused by variation in climate. In mechanical connections moisture induced strains in combination with boundary conditions that introduces constraints can lead to crack development and in turn weakening of wooden structures. Previous application of fracture mechanics typically focused on crack development caused by pure mechanical loading, see e.g. [3] for methods summarized and typical applications. Within the scope of the current work a numerical model is presented to simulate moisture driven crack growth within the beam/column dowel group connection shown in Figure 1. The model consists of two dimensional hygro-mechanical plane stress and XFEM analysis coupled to a nonlinear transient moisture flow analysis. A visualization of the considered problem is given in Figure 1. This figure shows a beam to column connection, which is exposed to natural climate variation (a). A schematic description of the problem is shown in Figure 1 (b). Figure 1 (c) shows simulated moisture content gradient and significant cracked beam because of the deformation constraints imposed by the dowels. The transient non-linear moisture flow was modelled using Fick’s law of orthotropic diffusion, using different diffusion coefficient in the two main directions, the length direction of the beam (assumed parallel to the fibers) and the direction perpendicular to that. The moisture transport in parallel direction was taken to be dominant. The shrinkage coefficients experience different values in perpendicular and parallel direction, αperp and αpar, respectively. For the fracture model, the critical energy release rate, GIC, is set to 300 J/m2, the strength in the perpendicular direction, ft,perp, to 2.5 MPa and the stiffness perpendicular and parallel to the length directions of the fibres are Eperp= 500 MPa and Epar= 10 000 MPa respectively.

    Automatic detection of pith location along boards of Norway spruce on the basis of data from optical scanning of longitudinal surfaces2019In: CompWood 2019 - International Conference on Computational Methods in Wood Mechanics - from material properties to Timber Structures, Växjö, Sweden, June 17-19, 2019, Växjö: Lnu Press , 2019, p. 64-64Conference paper (Refereed)
    Abstract [en]

    Different mechanical and physical properties of wood are related to the location of pith. Norway spruce wood from the centre of logs, close to the pith, is characterized by lower longitudinal MOE, larger spiral grain angle, and larger longitudinal shrinkage coefficient than what wood farther away from the pith is [1]. Thus, knowledge of pith location along timber boards may play an important role in both appearance grading and in assessment of mechanical properties such as strength [2]. The current work aims to develop an algorithm which is capable of automatically estimating the pith location of Norway spruce boards, along the boards’ length direction, by utilizing optical scanning of longitudinal surfaces. The initial step of the algorithm is to identify defect free sections along the timber board. This is done by utilizing data from tracheid effect scanning of the four sides of the timber board. Thereafter, a continuous wavelet transform (CWT), similar to fast Fourier transform, is applied on grey scale images from scanning, to analyse the variation of light intensity across the four surfaces at selected positions along the board. Obtained local frequencies correspond to the local annular ring pattern on surfaces. Then, assuming that annular growth rings are concentric circles with the pith in the centre, detected local annular ring wavelengths (using CWT) and artificial annual ring wavelengths corresponding to different hypothetical locations of pith are compared, and an optimization procedure is used to identify the location of pith that minimizes the discrepancy between the detected and artificial sets of annular ring wavelengths. Figure 1 shows grey scale images of short segments of longitudinal surfaces, graphs of the detected local annual ring widths, and a photograph of the board cross section where the determined location of pith is marked out. Preliminary results reveal that data from optical scanners and the suggested method allow for accurate detection of annular ring width and location of pith along boards.

    Have you heard the rumor about the connected consumer?: En kvantitativ studie om digital natives värderingar och förväntningar gentemot företag inom detaljhandeln.2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte: Studien ämnar undersöka skillnader mellan digital natives och digital immigrants i strävan efter att identifiera huruvida de förstnämnda kan anses vara en enskild målgrupp med unika karaktärsdrag. Vidare syftar studien till att kartlägga de två gruppernas värderingar i förhållande till företag inom detaljhandeln med huvudfokus på digital natives. Resultatet förväntas mynna ut i teoretiska och praktiska implikationer om vilka förväntningar digitala konsumenter har på företag inom detaljhandeln. Studien utförs ur ett konsumentperspektiv där konsumenterna undersöks.

    Frågeställningar: -Hur särskiljer sig digital natives från digital immigrants i värderingar gentemot företag inom detaljhandeln? och -Hur påverkar den digitala disruptionen digital natives förväntningar på företag inom detaljhandeln?

    Metod: Studien har en deduktiv ansats där en kvantitativ metod använts i form av en enkätundersökning. I undersökningen deltog 206 respondenter vars svar jämfördes mellan digital natives och digital immigrants i databearbetningssystemet SPSS för att hitta likheter och skillnader grupperna emellan. Även en förundersökning av exempelfallet Giraffen har genomförts i syfte att sätta resultatet i relation till verkligheten.

    Resultat och Slutsats: Studien påvisar att digital natives och digital immigrants skiljer sig åt till viss del, men inte i den utsträckning teorin förklarar. Vidare antyder resultatet att digital natives inte kan ses som en unik målgrupp när de besitter många liknande värderingar som digital immigrants. Därmed kan påstås att förväntningarna på företag är gemensamma för båda grupperna som kan samlas under benämningen digitala konsumenter.

    The other voice of Climate Change:A case study of community-based adaptivecapacities, through the analysis of activists’networks, building resilience, in South Africa2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The concept of climate change has been in the debate, not only at the international level, but also locally, for decades. However, activists around the world have come together to raise their voices and address once and for all the environmental crisis that we are facing today. In that sense, the following research analysed the voices of activists, and their network, in South Africa. With the aim to understand the formation of community-based adaptive capacities in relation to climate change, in communities.

    This Thesis was conducted as a case study in Bloemfontein, South Africa. The study included five semi-structured interviews directed to activist from Bloemfontein, as well as, secondary data conformed by five interviews conducted to members of the eco-building project ‘Qala Pheland Tala. Start Living Green’, and story-telling videos. As well as, the employment of participant observation, as part of the methodology.

    The study looked at climate change adaptability and resilience in different communities, based on the resilience theory proposed by Carl Folke. And itaimed to understand the influence that the activists’ network is having incommunity-based adaptation strategies to climate change. Further, the results were categorized with the framework that suggests a Resilience Model, as a set of networked adaptive capacities, designed by Norris et al. (2007).

    The analysis of the results concluded that the link between the activists’network and the communities, has helped to build adaptive capacities and resilient societies. At the same time, it proved that we need new strategies of action towards climate change, that foresee regenerative societies.

    Lobbyism bland ungdomsorganisationer: Nya former av påverkan i politiska processer2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Youth organizations in Sweden try to be a reliable part in the political agenda, to change and improve how the politics affect youths. This study aims to clarify how four different youth organizations work with their political questions: from hbtq-perspective and children’s rights to the right to hearing-aid and involvement in questions regarding youths. The method used for the study was both a comparative study of how the organizations work to improve and change the Swedish political agenda for the better, and interviews with the chairpersons of the four youth organizations for a bigger transparency in their methods.

    The results of this study are that there aren’t any strategy or method to affect and change how the political agenda works. Even though each of the four organizations are successful within their own area of expertise, it’s not always possible to apply the same methods on another organization with another structure.

    Pose AR: Assessing Pose Based Input in an AR Context2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Despite the rapidly growing adoption of augmented reality (AR) applications, existing methods for interacting with AR content are rated poorly, with surveyors of the area calling for better means of interaction, while researchers strive to create more natural input methods, mainly focusing on gesture input.

    This thesis aims to contribute to the aforementioned efforts by recognizing that technologies for consumer-grade smartphone-based pose estimation have been rapidly improving in recent years and due to their increased accuracy may have untapped potential ready to be utilized for user input. To this end, a rudimentary system for pose based input is integrated into prototype applications, which are constructed with both pose based input and touch input in mind.

    In this work, pose, pose estimation, and posed based input refer to using the distance and orientation of the user (or more precisely, the distance and orientation of their device) in relation to the AR content.

    Using said prototypes within a user interaction study allowed the identification of user preferences which indicate the approaches that future efforts into utilizing pose for input in an AR context ought to adopt. By comparing questionnaire answers and logged positional data across four prototype scenarios, it can be clearly identified that to perceive pose input as intuitive, the AR experiences shouldn’t employ a scale which is so large that it requires substantial shifts in the position of the user, as opposed to merely shifts in the position of the user’s device.

    A risk perspective of estimating portfolio weights of the global minimum-variance portfolio2019In: AStA Advances in Statistical Analysis, ISSN 1863-8171, E-ISSN 1863-818X, p. 1-22Article in journal (Refereed)
    Abstract [en]

    The problem of how to determine portfolio weights so that the variance of portfolio returns is minimized has been given considerable attention in the literature, and several methods have been proposed. Some properties of these estimators, however, remain unknown, and many of their relative strengths and weaknesses are therefore difficult to assess for users. This paper contributes to the field by comparing and contrasting the risk functions used to derive efficient portfolio weight estimators. It is argued that risk functions commonly used to derive and evaluate estimators may be inadequate and that alternative quality criteria should be considered instead. The theoretical discussions are supported by a Monte Carlo simulation and two empirical applications where particular focus is set on cases where the number of assets (p) is close to the number of observations (n).

    Be stubborn with your goals, but flexible with your methods: Paradoxical phenomenon within the fashion industry2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Seeing as fashion companies today have a proclaimed desire to act sustainably, we wanted to explore their explanations regarding the paradoxical phenomenon which is based on having CSR strategies, yet still advocating for consumption. The consumption rate in today’s society is not sustainable, and it appears that it has lead to some confusion regarding where to start or how to handle the paradoxes. Massive amounts of wastage, environmental pollutions and social issues in the supply chain are only a few components in the fashion industry which is full of paradoxical phenomena and tensions. This study aims to explore companies who have well established CSR principles, yet still contribute to mass production within the supply chain which consequently leads to overconsumption.

    Paradox perspective acknowledges tensions between and among various desirables, yet interdependent and at times conflicting sustainability objectives. In this study we look at the three aspects of CSR, and the tensions that exists when competing demands and goals of these aspects needs to be considered by the fashion companies. By viewing the three aspects of CSR through three dimensions (rearward, nearby and forward), we have analyzed our interviews and identifying different paradoxes that existed. The paradox of need for profit, the paradox of sustainability communication and the paradox of sustainable consumption. Conclusions drawn from these existing paradoxes are that fashion companies might be using more sustainable materials, but that the massive volumes of garments remain. Fashion companies are flexible with their goals of CSR, but stubborn with their methods of doing business, when the opposite is in fact required in order to improve the three aspects of CSR in various dimensions.

    Studies on Industrial-Scale Thermal Modification of Wood2016Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Wood as a raw material is useful for many purposes even though some properties are less than optimal, for example, dimensional stability and durability. These characteristics can however be improved by different treatment methods. Environmental awareness has led to an increased demand for environmentally friendly processes like thermal modification that does not add any chemicals to the wood in contrast to, for example, CCA-impregnated wood.This thesis mainly focuses on thermally modified wood from species such as pine, spruce and birch. The thesis present studies of physical attributes such as color, and chemical analysis of water-soluble compounds and degradation products. Treatment intensity is compared between two different industrial processes referred as Thermowood and WTT, which use respectively superheated steam and pressurized steam as heating media.Thermal modification processes darken the color of wood throughout its cross-section. The formation of darker color is related to a degradation processes that takes place during thermal modification. During thermal modification wood is exposed to temperatures between 160 - 220°C, and the temperature causes physical and chemical transformations that change some of the wood properties. Dimensional stability and durability are typically improved, but mechanical strength properties are usually negatively affected by the treatment.The studied wood species were Scots pine (Pinus sylvestris L.), Norway spruce (Picea abies L.) and Birch (Betula pendula L.). Treatments using pressurized steam were carried out under temperatures of 160°C, 170°C and 180°C, and treatments using superheated steam at normal air pressure were carried out at temperatures of 190°C and 212°C. Results showed that similar L* (lightness) can be reached at lower temperatures using pressurized steam compared to superheated steam. The residual moisture content after completed thermal modification was approximately 10% higher in wood treated with the pressurized steam process. It was found that despite an approximately 25°C lower treatment temperature, birch modified in pressurized steam was more acidic compared to birch modified in superheated steam. This will likely have further consequences, requiring more research concerning surface treatment and fixation.The thesis also includes the development of an industrial-quality control procedure based on nondestructive color measurements verified in industrial environment. Treatment intensity in industry is today certified by inspection of documented process schedule and measuring the temperature and time of the process. Quality control in this context refers to the measurement of wood color as an indirect measure of treatment intensity. The color in our study was measured using L*C*H color space. The study shows that it is possible for quality control purposes to measure the color of thermally modified wood from the surfaces of planed boards instead of sawdust or board cross sections that have been used in other studies.The thesis has a final section about academia-industry collaboration that describes how trust building was established through a fruitful relationship involving academia and regional wood products industry in northern Sweden. The study presents an example of a successful research and development alliance between university and a group of small- and medium-sized enterprises (SMEs). This alliance has been a great example on international collaboration involving researchers originating from Finland, China, Bangladesh, Spain, Russia and Sweden. Through an in-depth multi-year study of how the research cooperation developed, the paper describes how the involved companies successfully entered into a new segment of the market.

    Inskolning i förskolan: Samverkan mellan förskollärare och vårdnadshavare2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Introduction in preschool – Interaction between preschool teachers and parents. 

    Syftet med vår studie har varit att se hur samverkan fungerar mellan förskollärare och vårdnadshavare, samt att se om upplevelserna kring inskolningen var likvärdiga från båda parter. Studien utgår främst från anknytnings teorin och begreppen anknytning och föräldrasamverkan, men även kommunikationsteorin då en stor del av inskolningen handlar om informationsutbyte. Studien utgörs av en kvalitativ metod då vårdnadshavare samt förskollärare gavs möjlighet att svara på enkät och frågeformulär. Förskollärarna intervjuades och vårdnadshavarna fick svara på enkäter angående upplevelserna kring inskolning. Förskollärarna arbetar på den avdelning där de berörda vårdnadshavarna har skolat in sina barn. Förskollärarna belyser vikten av att ha en god kommunikation med vårdnadshavare för att minska risken för missförstånd. Resultatet har analyserats med tidigare forskning och teorianknytning som hjälp. Resultatet visar att vårdnadshavarna var eniga om att deras största orosmoment var att deras barn inte skulle trivas och vara ledsna på förskolan. Svårigheter som synliggjordes i resultatet från förskollärarna var kommunikationsproblem, det vill säga att familjer från andra kulturer har svårt med det svenska språket och att ta till sig och förstå den information som förmedlas vid inskolningens start. Dessa kommunikationsproblem hade förskollärarna olika strategier för att lösa.

    Med denna studie vill vi ge en bredare förståelse kring vårdnadshavares och förskollärares upplevelser om inskolning.

    Peacebuilding In Myanmar: A Case Study of State Influence on Civil Society in Karen State2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Myanmar, formerly known as Burma, has been going through a democratization process since 2011, despite different stages of conflict in several regions. In Karen State the main ethnic armed group, has signed the National Ceasefire Agreement in 2015. With the democratization process came a lot of changes for civil society. The role of civil society has been subject of many studies, with most researchers acknowledging that that role is dependent on the environment in which civil society operates. An important actor in this environment is the state. This research aimed to get a better understanding of how the state influences civil society and the work it does. To do this, the case of Karen State in Myanmar was chosen. The research question of this thesis was as follows:

    • How is the state influencing civil society and its functions in peacebuilding in Myanmar, specifically Karen State?

    To answer the research question, the research was conducted as a field study. An abductive approach was taken with the use of semi-structured interviews for qualitative data. To get comprehensive results, three types of organizations were interviewed: local CSOs, national CSOs and international CSOs. To analyse the results, two frameworks were used: the functions of civil society in peacebuilding according to Paffenholz and Spurk (2006) and the dimensions of the relationship of the state and civil society according to Müller (2006).

     

    The results show that civil society, in their view, is negatively influenced by the state. They are experiencing restrictions in performing some of their activities. The main worry for many of the organizations is the consequences of officially registering the organization. This requires giving up a lot of information to the government and makes them subject to influences from the state. Some other influences were the restriction of some activities, with even people getting arrested for their advocacy work. Collectively civil society is getting weaker, as the civil government is creating a divide in civil society with organizations that support them and organizations that are critical. Future research must go deeper into the influence of different state actors, and how each actor influences civil society in its own way.

    Ojämlik resursfördelning av sociala insatser till äldre.: En kvantitativ analys av sociala insatser i förhållande till omvårdnadsinsatser, samt fördelningen utifrån ålder, kön och civilstånd inom hemtjänsten i Karlskrona kommun.2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this quantitative study was to statistically test empirical knowledge that supports the idea of the existence of restrictive rationing and inequality in the distribution of resources for social support by variables of age, gender, marital status and number of nursing hours in the home care system. The material was obtained from internal records from the municipality of Karlskrona which constituted a population study, with which we performed regression analyzes to test the effect of the variables age and nursing hours on the variables escorting hours and  hours for social activation. An independent samples t-test were made to reveal any differences in mean values between the sexes, and a One way Anova analysis was made to check for differences of variance between each marital status. We found that men was rationed less hours of social support than women, that age had a positive effect on hours for social activation but a negative effect on escorting hours, that nursing hours had a positive effect on hours of social support and that there was a difference in mean hours of social activation between the married and the widowed, in the laters favour. We conclude that there is a restrictive practice in the home care system and that there is a difference in distribution between social categories, though it is not an unjust distribution of social support but rather an outcome of husbanding resources that points towards fairness, but we can recognize elderly of good health to be categories of attention as our analysis shows that they are are at risk to be overlooked.

    Vibrations in residential timber floors: A comparison between the current and the revised Eurocode 52019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The European standard Eurocode 5, a design method for timber structures,is currently under revision. In this study the draft for a reviseddesign method for vibrations in timber floors was compared to the currentmethod. The hypothesis of the thesis was that the revised designmethod might force some changes to the present construction practiceand that these changes may carry with them increased costs for the industry.Six common floor structures used in Sweden today were identifiedand for these floors design calculations were made according to the currentand the revised design method. It was checked whether the floorspassed the criteria in the two design methods and a comparison was madefor the only criterion which could be compared between the methods, thepoint load deflection. Floor structures could pass or fail the current designmethod based on two criteria, the point load deflection and the unitimpulse velocity response. All floors passed the current design methodexcept one which had a fundamental frequency below 8 Hz, because ofthe low frequency the current design method was not applicable to thefloor structure. In the revised design method the final result is a responsefactor and based on the response factor floors are given floor performancelevels. The seven step scale for the floor performance level go from I toVII where I is excellent and VII is unacceptable. All floor structures excepttwo achieved an acceptable floor performance level according to therevised design method. The two floors which failed were floors commonlyused in single family houses, they failed for a span length commonly usedtoday. A limited parametric study was performed where it was found thatthe modal mass used had a larger impact on the floor performance levelthan the mass per square meter included. For floors with a fundamentalfrequency above 8 Hz, including a higher mass per square meter resultedin a lower, i.e. better, response factor in all cases except one. For floorswith a fundamental frequency between 4.5 and 8 Hz, a higher mass resultedin a higher, i.e. worse, response factor. The study found that notall floor structures used in Sweden today are acceptable according to therevised design method therefore changes may have to be implemented andthese changes could result in an increased cost.

    MKV - framtidens viktigaste förmåga?: En kvalitativ studie som undersöker medie- och informationskunnighet hos ungdomar i samband med samhällsengagemang2019Independent thesis Basic level (degree of Bachelor), 180 HE creditsStudent thesis
    Abstract [en]

    Today’s complex and rapidly developed media landscape has brought a greater need for Media and Information Literacy. In order to live and express one’s opinion in a democratic society, it is considered a requisite to possess the skills that Media and Information literacy carries. This requisite mostly concerns the younger generation, since they are the ones growing up in today's media landscape.

     

    Many studies have shown that Media and Information Literacy is connected to civic engagement in various ways. Yet we have not encountered studies with Media and Information Literacy in correlation to civic engagement for a social issue. Therefore, the study will initially describe the main terminology and abilities concerning Media and Information literacy, this through a model formed by Renee Hobbs. Thereafter, the study presents how the abilities of what the model implicates execute in a civic engagement concerning a social issue.

     

    The study is conducted on eight adolescents in 9th grade at a school in Småland, using a qualitative method with semi-structured interviews. The result showed us that the abilities presented in the model, were practiced on a daily basis in the adolescent’s life in different ways. Further, it showed that the abilities played a significant role in order exert civic engagement. Interestingly it showed us that the social context was a remarkable reason for the adolescents to engage together.

    Industrial Validation of the Relationship between Color Parameters in Thermally Modified Spruce and Pine2016In: BioResources, ISSN 1930-2126, E-ISSN 1930-2126, Vol. 11, no 1, p. 1369-1381Article in journal (Refereed)
    Abstract [en]

    Thermal modification causes the darkening of wood throughout its cross-section because of chemical changes in the wood. After treatment, naturally light wood species look darker or even tropical, depending predominantly on the treatment temperature and processing time. This study investigates the suitability of using color measurement to determine treatment intensity at the industrial scale. The color was determined using the L*, a*, and b* color space, also referred to as CIELab, and the relationship between lightness (L*) and the color parameters (a*) and (b*) was investigated for thermal modification treatments at 190 and 212 °C. The wood species studied were pine (Pinus sylvestris L.) and spruce (Picea abies L.). The results showed that yellowness (+b*) and redness (+a*) had a significant prediction ability for class treatments at 190 and 212 °C, respectively. After treatment, there were no noticeable differences in color between the species, but sapwood was darker than heartwood in both untreated and thermally modified wood. The thickness of the boards had a proportionally darkening effect on the color values.

    Vägen ut ur gänget: Om manligheter, broderskap och svikna förhoppningar2019Report (Refereed)
    Abstract [en]

    Since the early 2000s, the phenomenon of gangs and the criminality associated with them have caused concern and attracted attention in Sweden. Various groupings that formed in socially vulnerable housing areas grew and positioned themselves alongside, and frequently in competition with, some of the established motorcycle gangs. Since then, clashes and showdowns between gangs have been repeatedly reported in the media and a number of political initiatives have been taken to address the problem. Who are the people who are attracted to these gangs? What sort of background do they have and what are they hoping to achieve by becoming a gang member? In this project, the process of leaving a gang and the support needed in this process was investigated, and crucial elements for the support to be effective were identified. In total, 20 men with a gang-member background and 42 people in formal support roles were interviewed to answer the research questions.

    It is almost exclusively men who are members and hold central positions in gangs, which is sometimes obscured in conceptual discussions about gangs. In this study, questions linked to manliness were important and, therefore, the construction of manliness in a gang environment and the subsequent reconstruction of manliness following the exit-process and what happens with this construction after a man has left a gang and is faced with new expectations was investigated.

    The answers gained from the study were multifaceted, indicating that each person must be understood individually. At the same time, distinct patterns could be discerned. In general, all of the 20 men who were interviewed described a tough upbringing, not least with regard to their own family and experiences at school. The negative experiences of not having a secure home environment and falling behind peers at school led to a sense of uncertainty and a desire to seek revenge. They perceived that their future prospects in “ordinary” society were very small and that the gang would be able to offer an alternative and compensatory arena. The men hoped that gang life would give them a sense of belonging and togetherness, sometimes termed brotherhood, and that in this setting they would be able to prove their worth. However, gang life often did not work out the way they had hoped. Competition with other groups and multiple challenges within the group, such as the expectation of prioritising the gang over family life, caused too much mental and social strain.

    Leaving the gang implied a renegotiation of what it means to be a man. In the gang, strength, toughness and never backing down were characteristics that were acknowledged and rewarded. For some of the men, this was in strong contrast with, for example, the values associated with parenthood. Taking responsibility for and caring about others had a polarising effect on gang life and the arbitrator was frequently their own children and family.

    The study also included about 40 interviews with people who, in their work role, have an opportunity to support the exit-processes. These persons were employed by the Swedish Prison and Probation Service, the social services, the police or by a non-profit organization. The work put into creating trust and building a relationship was a crucial part of the support activities. Many of the men had adopted a stance of having little trust in public authorities early in their lives and to challenge this position, personal commitment, a positive attitude, and substantial knowledge about gangs and criminality were necessary. In addition, in many cases, multi-dimensional support was needed, such as accommodation in a new location, protected identity and new social contacts. Many of the men had experiences of substance abuse and traumatic stress-related incidents, and they also had a great need to repair relationships and regain normal contact with their children and families.

    While some support persons were able to reach the men and become an important part of the change process, it was also noted that there were some circumstances which instead of strengthening the opportunities of adopting a new identity and life, seemed to weaken them. Both among the men themselves and among the support persons, there was criticism that the support system intended to help them to leave the gangs did not work satisfactorily. The criticism related to, for example, a perceived ineffective prison release and reintegration process as well as a lack of collaboration between authorities. In addition, we conclude that there is a great need for long-term planning and specialist knowledge to coordinate and increase the quality of support nation-wide.

Business administration III - Marketing. Interior Decoration and Visual Merchandising, Linnaeus University, Spring 2019. Purpose and research question The purpose of this study, from a business perspective, is to investigate and describe how fair organizers in Swedish design and furniture fairs, with a physical character, are working with service design to create value for exhibition organizers and exhibitors. Based on the purpose of this study, the following research question was formulated: How does fair organizers, in design and furniture fairs, work with service design to create value for exhibition organizers and exhibitors? Method A qualitative research method with a deductive approach has been implemented to answer the research question and purpose of the study. The empirical data has been collected through five semi-structured interviews from a business perspective. In addition to this, interviews from a customer perspective and an expert perspective have been made. The empirical material of the study has been analyzed with the theoretical frame of reference as the starting point. Theory The theoretical references used in this study consists of service dominant logic, co-created value and the experiential world of the customer, which is the first step in the framework of Customer Experience Management. Finally these theories will lead to service design, which is the latest perspective in order to create valuable customer experiences. Conclusion The study shows that service design is an important approach to use to be able to create successful companies, although only partially applied by exhibition organization in design and furniture fairs. Planning and organizing can be seen as a strength. Furthermore, due to the limited contact between the two parties, the expectations that the exhibitors had were not met by the exhibition organizers. The study also shows that if service design is applied, value can be created for both fair organizers and exhibitors, in the form of circular value. Keywords Design, service design, design- and furniture fairs, exhibit organizers, exhibitors, customer experience, value, interaction.

    Folkbibliotek i glesbygd: kunskapsläge och erfarenheter2019Report (Other academic)
    Abstract [sv]

    Den här kartläggningen undersöker verksamheten i folkbibliotek i glesbygdsmiljöer i förhållande till utpekade verksamhetsområden och målgrupper i bibliotekslagen. Syftet är att se om det finns några områden i bibliotekslagen som är svåra att leva upp till och i så fall varför. Undersökningen genomförs med fokus på de prioritetsområden i bibliotekslagen som tydligast relaterar till folkbibliotekens verksamhet; läsfrämjande, tillgänglighet, prioriterade grupper, kvalitet och allsidighet i mediebeståndet, digital delaktighet samt samverkan mellan olika delar av bibliotekssektorn.

    Kartläggningen består av två delar:

    1. En kunskapsöversikt, där svensk och internationell biblioteks-och informationsvetenskaplig forskning med fokus på glesbygdsrelevanta biblioteksfrågor diskuteras. Avsnittet rymmer också kommentarer till ett antal nyligen genomförda svenska utredningar ur ett glesbygdsperspektiv.
    2. En empirisk studie, där bibliotekarier och biblioteksassistenter deltagit i intervjuer och gruppdiskussioner om bibliotekslagens prioritetsområden i workshopform. Sammanlagt har 47 bibliotekarier och biblioteksassistenter från 34 kommuner i fyra regioner deltagit. Detta har kompletterats med 10 intervjuer med representanter för ytterligare kommunbibliotek, de samiska biblioteken och fyra regionbibliotek.

    Resultatet visar att förutsättningarna för folkbiblioteken i glesbygdskommuner varierar. Påtagligt är att laguppfyllelse sker trots ofta mycket små och ansträngda resurser. Detta påverkar möjligheten att bygga verksamheter utöver det som krävs för att enbart hålla biblioteken öppna. Särskilt hårt drabbat är läsfrämjandearbetet, arbetet med de nationella minoriteterna och urfolket samer samt frågor som rör digital delaktighet och digitalisering. Glesbygdsbibliotekens arbete beskrivs regelmässigt i undersökningen som utpräglat socialt, både i meningen att till exempel läsfrämjandearbetet i hög grad bygger på en upparbetad närhet mellan bibliotekarier och användare och att glesbygdens folkbibliotekarier idag får ta en mängd arbetsuppgifter som kommer sig av att det offentliga samhället på många platser dragit sig tillbaka helt. Detta påverkar både bibliotekens identitet och legitimitet.

    Kartläggningen pekar på ett brett behov av långsiktiga statliga stimulansmedel i linje med Stärkta bibliotek, ett behov av en tydligare, mer transparent, nationell samordning av digitala medieresurser samt ökade initiativ för att tillgodose de kompetensbehov som finns och som i glesbygdsbiblioteken är mycket svåra att tillgodose.

    Kundlönsamhetsanalyser: En studie om hur företag inkluderar kompletterande faktorer i sina kundlönsamhetsanalyser för att uppnå ett mer komplett beslutsunderlag för styrning av verksamheten2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background and problem: Customer profitability calculations are needed for companies to obtain knowledge of the profitability of their customers. The information then constitutes the basis for decision-making for the managing to increase total customer profitability. For many companies there exists some factors which are impossible or difficult to include within a customer profitability calculation, however these factors affect the total customer profitability. Therefore companies need to complement the calculations with these to receive a more accurate customer profitability analysis which makes managing towards the company’s comprehensive view possible. The difficultness for the companies is how these factors should be handled, valued and used within the companies managing.

    Purpose: The purpose with this paper is to create understanding about how companies fulfill a customer profitability analysis that concludes factors which are used as a compliment for the traditional customer profitability calculations. The study also includes how companies manage their organizations based on the customer profitability analysis.

    Method: A qualitative study with semi structured interview has been used. An interview guide has been the basis for the structure of the interview.

    Conclusion: When analyzing the empirical material, we found that companies adjust and choose the calculation method for customer profitability calculations based on how the business is structured. They value the complementary factors mostly through knowledge and experience. The customer profitability analysis are used as a basis for decisions regarding managing actions regarding improvements of the companies processes, priorities of resources and the influence by the customers behavior for the purpose to achieve an optimal customer profitability for the companies.

    Dynamic sampling rate algorithm (DSRA) implemented in self-adaptive software architecture: a way to reduce the energy consumption of wireless sensors through event-based sampling2019In: Microsystem Technologies: Micro- and Nanosystems Information Storage and Processing Systems, ISSN 0946-7076, E-ISSN 1432-1858Article in journal (Refereed)
    Abstract [en]

    With the recent digitalization trends in the industry, wireless sensors are, in particular, gaining a growing interest. This is due to the possibility of being installed in inaccessible locations for wired sensors. Although great success has already been achieved in this area, energy limitation remains a major obstacle for further advances. As such, it is important to optimize the sampling with a sufficient rate to catch important information without excessive energy consumption, and one way to achieve sufficient sampling is using adaptive sampling for sensors. As software plays an important role in the techniques of adaptive sampling, a reference framework for software architecture is important in order to facilitate their design, modeling, and implementation. This study proposes a software architecture, named Rainbow, as the reference architecture, also, it develops an algorithm for adaptive sampling. The algorithm was implemented in the Rainbow architecture and tested using two datasets; the results show the proper operation of the architecture as well as the algorithm. In conclusion, the Rainbow software architecture has the potential to be used as a framework for adaptive sampling algorithms, and the developed algorithm allows adaptive sampling based on the changes in the signal.

    Vägmodellering baserad på laserskanning för virtuella fordonssimuleringar2019Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Product development is necessary to compete in today´s vehicle industry. During the design process the largest possibility to affect the end product to the better exists. One way to achieve product development is to apply new technology. Through application of terrestrial laser scanning digitalized road models can be achieved and be used in simulations. In these simulations, vehicles can virtually do a trial run and thereby shorten the dimensionprocess. Laser scanning of hilly terrain is complex and therefore groundwork of hilly roadways in simulations is missing. 

    This study refers to present different types of laser scanning methods and expand the groundwork for virtual simulations in the dimensionprocess of dumpers. The vision is to create virtual roadways which can be used in simulation models.

    Three main techniques of laser scanning are presented in the theory chapter. Further on terrestrial laser scanning has been used on Volvos test track in Målajord and with this scanning data as groundwork a road model, which can be used in vehicle simulations, has been created in Matlab. The road model is well representing the real roadway, which indicates that terrestrial laser scanning is a well working method for this purpose.
