    Undersköterskans erfarenheter av delaktighet och dess inverkan på hälsan2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Undersköterskans välbefinnande och hälsa kan påverkas av arbetsmiljön där inflytande och påverkan på arbetsinnehåll har betydelse. Tid för återhämtning kan vara svårt att få till stånd då undersköterskan arbetar oregelbundna arbetstider. Arbetsuppgifter som kan leda till en god hälsa och arbetsmiljö kan vara känslan av delaktighet och inflytande. Syftet med detta examensarbete var att beskriva undersköterskans erfarenheter av delaktighet och dess inverkan på hälsan. Examensarbetet genomfördes med en kvalitativ ansats och som metod för datainsamling användes semistrukturerade intervjuer. Individuella intervjuer genomfördes med sex undersköterskor som arbetar inom äldreomsorgen. Innehållsanalys användes som metod för att bearbeta data.

    Resultatet visar att tid för återhämtning och att kunna medverka och ta ansvar har betydelse sett ur individens perspektiv. Arbetsgruppen har betydelse för hälsa och delaktighet genom samspel, öppenhet och förmågan att lyssna på varandra. Ur ett organisatoriskt perspektiv är samspel med andra professioner och upplevelsen av en hälsosam arbetsmiljö viktigt. Chef för verksamhet bör tillsammans med undersköterskor skapa en miljö där välbefinnande råder genom delaktighet i en hälsosam och hållbar organisation. Genom detta förhållningssätt kan arbetsrelaterade problem förhindras vilket i sin tur kan bidra till en förbättrad hälsa hos den enskilde och att minska sjukfrånvaron.

    Kroppslängd: En studie om kroppslängdens påverkan på passformen2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This report is a bachelor essay in garment technology. The background for this report is a field study that took place during spring 2019. The field study was carried out at a fashion company, specifically at a department that produces women’s clothes. During that period the department was in the process of creating garments for women of short stature. That sparked the idea to investigate the field a bit closer, due to the big demand for well fitted garments among shorter women. The aim of the study is to identify differences in fit between a size for women of average height and women of shorter stature, and to analyze the market’s assortment of shorter sizes. In this study three basic patterns were constructed. The first pattern was created from a standard measurement chart for women of average height. The other two was constructed for shorter women. One was developed according to the market’s body measurements and the other based on a standard measurement chart for women below average height, to be able to determine differences in fit. The fit was then verified through fittings on models of shorter stature. The result showed that the pattern developed from a standard measurement chart had a better fit than the pattern based on the market’s body measurements.

    Gradering av stora damstorlekar: Liv med avprovningsstorlek 502019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study examine how a grading system are compared to the company’s graded base pattern. The study is an assignment on a Swedish fashion company. The company used to have a section for plus-sizes in their clothing line, but decided to remove it. Instead, they merge the whole grading system into one. They have tried to find the right intervals of grading in the biggest sizes, which makes it interesting to compare their grading to other grading systems.

    The methods used in this study are grading, comparison of patterns and 3D prototyping in Lectra Softweares Modaris, 3D prototyping and KaledoStyle. Sewn samples have been fitted in size 50 and analyzed by a test protocol.

    The result of the study shows that the grading system from the company is comparable with the other grading system. The most distinct part that separates the grading systems is the shoulder length in the bigger sizes. The company has chosen to stop their grading, which the other grading system does not. The other grading system follows dada where body measurements are established.

    Psykisk ohälsa i förskolan: En undersökning av det förebyggandearbetet av barns psykiska ohälsa i förskolan2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Studien syftar till att undersöka om, och i så fall hur, pedagoger i förskolan arbetar förebyggande av barns psykiska ohälsa. Utgångspunkten för studien är teorier om barns psykiska hälsa utifrån ett socioemotionellt, sociokulturellt, kognitivistiskt och psykoanalytiskt perspektiv. Metodval för studien har varit en enkätundersökning baserad på dels en kvantitativ metod och dels en kvalitativ metod.

    Resultatet av studien visar på pedagogers grundläggande uppfattningar om området psykisk ohälsa. Det finns en varierad definition av begreppet, där pedagoger beskriver begreppet utifrån både ett individperspektiv och ett objektivt perspektiv. Definitionen av begreppet ”psykisk ohälsa” kan i viss mån kopplas till teoretikernas beskrivning av begreppet. Vidare redogör pedagogerna för olika arbetsmetoder i arbetet med att förebygga psykisk ohälsa hos barn. Dessutom framkommer pedagogers efterfrågan av fortbildning.

    Frågeställningar

    - Vad innebär begreppet ”psykisk ohälsa” för pedagoger och finns det något samband med teorier om barns psykiska välmående?

    - Vilka arbetsmetoder menar pedagoger att de använder sig av för att förebygga psykisk ohälsa hos barn, och på vilket sätt skulle dessa kunna utvecklas om utgångspunkten ligger i teorier om barns psykiska välmående?

    - Vad har pedagogers fortbildning för betydelse i det förebyggande arbetet av barnspsykiska ohälsa?

    Sexualisering av kvinnor i modereklam: en undersökande studie om konsumeternas attityd mot varumärken2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The focus of the study is fashion oriented advertising that has been analysed according to chosen criteria, which puts the study within the frames of textile management. The study aims to introduce the reader and give a background to the subject of choice by motivating the relevance of the study. Thereafter the problem formulation leads to a presentation of the purpose and research questions of the study. The purpose of the study is to describe and examine how women's portrayal as sex objects in luxury brand advertising affects consumers attitude toward a brand. Also differences between effects on men and women were examined. To gather the empirical findings we used an image analysis method and and an online-survey. The image analysis was made up of five different advertising images from luxury brands, that were later analysed with chosen criteria to grade an image based on how sexualised it was. The online-survey was based on these analyzed images, thereafter questions about brands were formed with inspiration from earlier studies. The sample was made up by Swedish clothing consumers, a stratified random sampling that we combined with snowball sampling. The findings of the study points to a majority of the participants being negatively affected by sexualised advertising. Which makes the consumers attitude toward a brand negative and changes their buying habits. Although the study also find that there are surprisingly many consumers who will continue buying products from a brand that use sexualised advertising, even though the consumers claim to have been negatively influenced. The differences that were found between men and women were that women seem to be more aware of sexualised advertising than men, and that there are far more women who intend to change their buying behavior to match their attitude toward a brand. A much larger portion of men answered that sexualised advertising do not affect their perception of the brand, compared to women. Although some of the respondents, both genders, are willing to continue buying from the brands that affected them negatively. For further research we suggest to examine this topic from a corporate perspective to understand how the companies that use this type of sexalized advertising are thinking.

    Sjuksköterskors erfarenheter av bedömningsinstrumentet: Klinisk slutexamination av sjuksköterskans vårdande utifrån omvårdnadsprocessen2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Landets sjuksköterskestudenter genomgår i slutet av sin utbildning ett slutprov, där både teoretiska och praktiska moment ingår. Tillvägagångsättet för bedömningen av studenten sker med varierande metoder och utifrån olika bedömningsinstrument beroende på vilket lärosäte studenten studerar vid. Bedömningsinstrumentens gemensamma syfte är att de ska utgöra en garanti för att studenten når den kunskapsnivå som krävs för en svensk sjuksköterskelegitimation. Studenten vid Högskolan i Borås ska inför sin examen genomgå kliniska slutexaminationer och lärosätet har valt att tillsammans med vårdverksamheten utveckla en Boråsmodell: Klinisk slutexamination av sjuksköterskans vårdande utifrån omvårdnadsprocessen, här förkortat (KSE).

    Syftet med studien är att beskriva handledares erfarenheter av att handleda och bedöma studenter utifrån bedömningsinstrumentet KSE. Detta har gjorts med hjälp av sju intervjuer som analyserats utifrån en tematisk metod. Resultatet pekar på att handledarna upplever en tydlig struktur, vilket förenklar handledningsprocessen och minskar stressnivån. Erfarenheterna visar på att bedömningsinstrumentets enkelhet tillsammans med och den handledningsmodell som tillämpas, medverkar till en personlig process hos både handledare och student genom att reflektionen ges stort utrymme. Resultatet ger ett genomgående positivt intryck. Det framkommer dock vissa otillfredsställande detaljer i bedömningsinstrumentet och moment som upplevs påfrestande. Upplevelser som tycks påverka negativt som erfarenheter av samvetsstress. Diskussionen tar fasta på de erfarenheter och tankar som förmedlats om bedömningsinstrumentet i relation till yttre faktorer, där förslag på kliniska implikationer avslutar studien.

    Trådlös laddning med en textil: Kan en broderad spole möjliggöra induktionsladdning av en mobiltelefon?2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The development of electronic textiles has increased significantly during the last ten years. By integrating electronic components or using conductive thread you can create textiles with different technical functions. CEVT is a innovation company within the automotive industry who have gained interest in electronic textiles. The department of innovation want to explore the possibility to integrate electronic textiles into future cars. The mission they have assigned us is a sub-goal in a larger end goal in which we will investigate whether one can develope a textile that can charge a phone wirelessly. To do this, a textile transmitter coil must be produced to enable the induction charging, which is what wireless charging really means.The method that was chosen to produce the textile transmitter coil was embroidery and the conductive thread that was used was a silver plated polyamide thread (HC12) from Sheildex. The thread had a resistance of <100 Ω per meter and some difficulties arose early on, where the resistance of the embroidered coil was to high. To reduce the resistance multiple stitches were sewn together and the conductive thread was also used as a lower thread. The resistance of the final coil had an average of almost 15 Ω which was significantly higher than desired.Tests were made to measure the inductive capability of the embroidered coil. This was done by measuring the power transmission between an embroidered coil and a Samsung Galaxy s8 reciever coil. The results showed that a power transmission was enabled, which means that it works. Though the power transmission was a lot lower when compaired to a commercial transmitter coil that was tested at the same time.The project did not result in a fabric that could wirelessly charge a mobile phone. Nevertheless, the test results showed that it is possible, since a power transmission did occur between the textile coil and the coil from the Samsung. Further research and optimization of the textile coil would be required to realize the induction charging textile. Two interesting ways to go would be by using another embroidery technique called Fibre Tailored Placement (FTP) or by developing a new conductive embroidery thread, with a lower resistance.

    Ett hållbart läder: En jämförande studie mellan konventionellt läder och naturmaterialet Piñatex2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Leather has been used by humans for centuries and it is one of the most resistant materials that exists today. This leads to a high production of leather, where the largest part comes from chrome tanning, which stands for approximately 90 % of the total leather industry. Because of today’s awareness surrounding the environment and how leather affects it, demand for alternative materials are increasing. Piñatex is a material based on the leaves of the pineapple plant, which is turned into a non woven material, looking alot like leather. Although it is not created as a substitute for leather, the areas of use are the same. Piñatex can be an alternative material when it comes to durability but also from an environmental point of view. The purpose of this report is to study the manufacturing processes for Piñatex, chrome tanned leather and vegetable tanned leather to yield a higher understanding for their environmental impact. Futhermore, material testing is carried out to see how the technical properties differentiate between the materials. Test results from this study show that the materials have different advantages and disadvantages depending on which test has been carried out. It is hard to know exactly how big the environmental impact from the different manufacturing processes are, but chrome tanning is probably the one with the highest impact. In the end, the desirability of a certain material all comes down to user preferences and for which purpose the material will be used.

    Undersökning av handskens gradering2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    One of the problems that companies who wishes to go into glove production faces today, is that there is no standardized measurements or constructions. There is a praxis for width grading, where you measure the hands circumference around the knuckles, in inches, but the are no such praxis for the length of the glove. This study compares different length gradings that are available on the Swedish market. By measuring and comparing different glove brands, three different finger length variations were found for size 8 as well as three different grading intervals between the sizes; 15mm, 10mm and 5mm. The grading intervals are divided equally between fingers and palm. Gloves in sizes 6-11 were constructed, sewn and finally fitted on 28 test subjects, both male and female. The subjects also submitted a questionnaire about their hand measurements, which gloves they tried on, which glove they preferred and if they would like any information about which body measurements the glove is fitted to when buying gloves. For size 8 it was found that four subjects preferred a finger length of 8,5 cm on the middle finger while one preferred the shorter length of 8cm. For the other sizes, graded from a basic size of 8,5 cm at finger length, the preferred grading was the one that gave the glove the longest fingers, followed by the grading of 10mm. From these results it is clear that there is a need for different lengths for each glove size and that the customer would appreciate a measurements chart that shows what hand measurements the glove will fit.

    SLOW FASHION: Ett genomtänkt och planerat köp som kräver större uppoffring?2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In contrast to fast fashion, which is tussled with mass production and with short lead times, the slow fashion movement has arrived and been adopted by several actors on the fashion scene. Slow fashion wants to inspire with a sustainable and timeless wardrobe that is well thought out and stands strong against the fashion world's quick turns and then, contribute so the consumption is not increasing in quantity but in quality. The problem in sustainable consumption is that consumers often choose not to act on the basis of a sustainable perspective even though their intention says it. Research show that there is a gap between what consumers intend to do and what they actually do, so called attitude-behavior gap. The aim of this study is to determine characteristics and examine customer behavior in connection with shopping slow fashion. Contemporary research has provided support for the gap and its existence, in our study we want to develop that result into further analysis. We want to investigate the theory about the attitude-behavior gap in contrast to slow fashion and its customer behavior and the reasons behind a purchase.Why does a consumer choose to buy slow fashion products and what is the profile of a slow fashion consumer? To understand and interpret the empirical material from this study, a theoretical framework was designed around three different theories, the Attitude-behavior gap, the Consumer culture theory and the theory of needs identification.The result of this study shows that reasons such as identification, price, timelessness and high product quality affect the consumer to buy slow fashion products. Further, it shows how these reasons will get prioritized and planned in a consumer journey within the buying process. The planning itself is through all stages by every respondent and the insights will be discussed further. Slow fashion are therefore consumed with engagement and a strong price acceptance. The study will continue in Swedish

    Jag följer dig för att jag litar på dig: en studie om relationen mellan följare och influencer2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Influencer marketing is today seen to be the most effective way to reach customers in their everyday life. Today, companies marketing budgets consists mostly of influencer marketing activities. Companies are searching for influencers who can communicate and convey the companies message through their social media platforms to their followers - the companies potential customers. The following study aims to investigate the relationship between influencers and their followers and how this affects the followers trust towards the influencer. This will be done by evaluating followers perception of the influencers honesty and authenticity and further analyze how this affects the influencers trustworthiness in their collaborations with a brand. To understand how the influencers trustworthiness is affected by their choice of collaboration, the relationship between the influencers personal brand and the company's identity will be investigated further. This will be done to understand how brand fit affects the followers relationship in terms of trustworthiness. The study consists of qualitative semi structured interviews which aims to provide a depth to the survey. A quantitative digital survey has also been done to provide the reader with a general understanding of young women’s relationship with influencers on Instagram. By analyzing the empirical material we find that honesty in influencers collaborations will generate in followers trust towards the influencer. If the influencer collaborates with a company that is not in line with the influencers personal brand, the followers trust towards the influencer will be damaged and the influencer will be seen as dishonest and fake. This will also damage the influencers personal brand. Further, we find that long relationship between the influencer and their followers creates a more stable relationship in case of trust, honesty and authenticity even in the influencers collaborations. This is also the case of ambassadorship, where a long relationship between an influencer and a brand correspond with each other. This reflects in generated trustworthiness from the influencers followers.

    Vill du köpa en påse?: Tillgänglig information vid köpsituation kan bidra till en hållbar konsumtion.2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Constant change is closely associated with the fashion industry, as new trends and styles tent to change continuously. In the Western world, people consume considerably more fashion products than what the natural resources allow. The fashion consumers, however, gained an insight into the fashion industry´s negative environmental impact in 2017. A new law was founded to alert the fashion consumers of the negative effect of the shopping bags, especially made with plastic. In association with the new law, an organization, naming One Bag Habit was created. This led the fashion consumers to think extra before deciding to consume a shopping bag when they made a purchase of fashion item. Due to One Bag habit, fashion consumers now avoid from consuming shopping bags because of environmental aspects. The reluctance to consuming a shopping bag in addition to the fashion purchase has decreased yet impacts on the actual fashion consumption have not changed. Previous research has identified an attitude-behaviour gap between how fashion consumers value sustainable products and their actual behaviour in accordance with these values. This has led to this paper highlighting how this contrast is formed between consuming fashion products and refraining from the shopping bags because of environmental reasons. This study has a textile management approach, which means that the study is primarily aimed at companies in order to help them understand how fashion consumers value and act in different purchasing situations. This study will examine how fashion consumers consume shopping bags in relation to fashion products. The findings will contribute to creating an understanding of the created contrast between sustainable consumption regarding shopping bags and non-sustainable one regarding fashion consumption itself. Moreover, the findings will contribute to a deeper understanding of why the attitude-behaviour gap has created such a contrast among the fashion consumer. In order to understand and interpret the empirical material of this study, a theoretical model of attitude-behaviour gap was created. In addition, an understanding of how needs are created among consumers will be contributing to the formation of the theoretical framework. Furthermore, data was collected through qualitative interviews, three focus groups, and an observation. The data sample frame consisted of students from three different universities in Sweden (the Swedish School of Textiles in Borås, University of Gothenburg and Mälardalens University in Västerås). The findings of the study show that fashion companies need to be more specific when informing the fashion consumers on why and how they can act more sustainably when consuming fashion and shopping bags. In addition, the sustainable fashion products should be comparable in prices terms to non-sustainable fashion products in order for fashion consumers to act sustainable. Finally, it is suggested that the sustainable fashion products have an appealing designs in order for the fashion consumers to invest in sustainable fashion products.

    Textil produktförbättring: Hur konsumenter och klädföretag kan interagera för att utforma en produktförbättring2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    New products are crucial for successful growth and competitiveness. A new product can sometimes be an improvement on a previous product in a company. Companies strive to deliver something that customers inquire for and it is at those times important to listen to consumers regarding what they want and how the products are designed, produced and managed. Consumers want a dialogue with companies as they want to be involved in the product development process. Consumers expect answers from companies and want to create a relationship. The purpose of this study is to get answers on how the consumer thinks about textile product improvement within clothing and how the product development process for a product improvement on a garment can look like. The study is based on a literature study and an empirical study. The literature study concerns the topics consumer behavior and New Product Development. The empirical material is from interviews with a strategic material developer and a global customer relationship management manager. In addition to this a questionnaire survey has been conducted aimed at consumers. Based on these, the results show several problems that can occur during the product development process regarding a product improvement. The result also shows how customers want to interact with the selected company, which factors that affect the consumer and how the consumer wants to be involved in a product improvement. The conclusion that the study has come up with shows that consumers want to participate and influence the product development process. Many of the consumers are dedicated regarding what the company is developing and therefore want to participate and affect. In the product development process, it showed that many technical problems could occur. Many tests and changes were therefore needed to achieve a good result.

    Att specificera ullgarn: en jämförande undersökning av ullgarn för mattor2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study investigates two yarns made of 100 % wool that have been ordered with the same specification but from different suppliers. The yarns are used by a company that produces carpets. During weaving these yarns don’t behave the same and therefore problems have appeared in production. The aim with this study is to investigate why the two yarns behave differently. A literature study has been conducted to assemble information about wool properties and how these can have an affect on different processing steps typical for wool. From these findings it was concluded which tests to perform during this study. Tests that measured tensile properties, moisture content and twist liveliness were first performed on uncoloured yarns. At fiber level the fibre width, length and crimp as well as proportions of medullated fibres were measured. A medullated fibers is a fiber with a bigger core than a regular wool fibre. Tests that showed significant differences were also carried out on coloured yarns to see if the differences remains after dyeing. Together with the test results and information from litteratur it's discussed how differences in parameters are related to the yarn properties and if it's possible to translate these findings into new demands for a yarn specification. These were considered to be fiber width and length specified with both a mean and distribution, proportion of medullated fibres, E-module and to specify the mechanical properties with cN/tex instead of only Newton to get a value that is more true to the variations in wool. It's concluded that the yarns differ sufficiently at fiber level to give them different properties, which shows in the mechanical properties. There is a difference in the two yarns ability to stretch and this can explain problems that arise during weaving. In addition to suggest parameters to specify it's discussed how desiding a standard to follow for measures and how to analyze the results could help to ensure demands in the specification.

    Best Before: A selective service life analysis of denim fabrics with a focus on washing and drying degradation to optimize their recycling efficiency2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Resource scarcity and increasing environmental pressure have raised the stakes for rethinking material efficiency and textile recycling potential. As current practices fail to feed a closed loop recycling system, this research aims to contribute to the improvement of prevailing practices regarding denim as one of the most popular apparel materials worldwide while focusing on the issue of increasing amounts of discarded post-consumer textiles. The superordinate objective to define the optimum point for denim recycling to retain the value of the cotton fibre as long as possible in a closed loop system, thereby elevating the recycling efficiency, can be considered a key driver for the present research. The following data acquisition is constructed and executed along a mixed method research, in which a qualitative approach based on expert interviews informs and builds up on the quantitative counter part of laboratory use simulation testing on two different denim fabrics and vice versa, leading to an embedded research design. A subjective assessment of potential alterations of the denim fabrics’ visual and tactile characteristics, caused by the use simulation, provides quantitative data through an employed expert panel, which is enhanced by objectively recorded results from the conducted tear strength test and comparative weight investigation to inform changes regarding the physical properties. The applied research methods provide parameters to monitor the decomposition and weakening of the overall fabric structure throughout the experiment. The analysis of the data allowed to assign the number of washing and drying cycles, that a denim garment has undergone, to a corresponding degree of degradation. The presented findings are a valuable resource for developing and innovating current open-end recycling options. The maintenance of the raw material value throughout various reprocessing cycles can counteract the elevated natural fibre scarcity. The insights on the material and process level build a fundament for the successful operationalisation and management of sustainable recycling practices. Further research in this field can pave the way towards value retaining circularity.

    Supercritical carbon dioxide as a green media for simultaneous dyeing and functionalisation: A study on disperse dyeing and silicone functionalisation for water repellency of polyester fabric2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Textile processing methods such as conventional exhaustion dyeing, pre-treatments and printing consume high amounts of water and use partly toxic and hazardous chemicals which are non-degradable. These chemicals (e.g. excess amount of dye, additives and catalysts) remain partially in the waste-water which is drained out and ends up polluting the environment. The supercritical carbon dioxide dyeing technology presents an eco-friendly and water-free method with reduced use of chemicals and energy. The benefits of such technology are currently not overcoming the relative high investment costs which impede its full implementation into the textile industry. This study presents an approach to extent the application of the eco-friendly supercritical carbon dioxide technology. It combines the well-studied supercritical carbon dioxide dyeing process for polyester with the functionalisation process to obtain water repellent surface properties. As water repellent (substance) environmentally benign silicones are used. Results showed that the simultaneous dyeing and functionalisation process was feasible assessed by the compatibility of the dye and silicone in the system. Silicone and dye did not interfere in each other’s functionality (colour strength and water contact angle). Further the process temperature and silicone molecular weight showed no influence on the colour strength of the fabric whereas the water contact angle (water repellence) increased with increasing temperature. The resulting polyester fabric showed acceptable colour strength yet did not obtain sufficient water repellent properties despite the increase in water contact angle of the treated samples to the untreated reference sample. The poor water repellence is suggested to be caused by the hydrophobic functional groups of the silicones oriented towards each other rather than toward the outer fabric surface. Overall the thesis is promoting research which combines eco-friendly technologies including environmental benign chemicals for the textile industry. Silicones are widely used in textile processing not only as water repellents, but also as anti-foaming agents, lubricants and softeners. Therefore a water-free and eco-friendly application method can benefit a wide range of finishing processes.

    Environmental impact of textile barriers: A comparative study of coated and laminated textile2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis examined how the sustainability of laminated and coated textile barriers can be compared by analysing them through an environmental and functional perspective. This was done by building an evaluation model in which an analysis of the functional performance and an analysis of the environmental performance was combined and applied on a case study of a laminated and a coated material used for workwear. A Life Cycle Assessment (LCA) was used to evaluate the environmental impact. To evaluate the functional performance a series of material testing was made for tear strength, waterproofness and permeability. The LCA measured the environmental impact in terms of water use, climate change, and human toxicity. The results showed a similar impact on climate change and water use for both barriers. The assessment of human toxicity showed that the solvent dimethylformamide, used in the coating paste, meant a potential risk for human health. From the material testing it could be stated that the coating performed better in terms of tear resistance and waterproofness, but that the laminate showed more even results and higher breathability. To conclude, the study showed that the production of the coated textile barrier had the largest environmental impact due to the use of a toxic solvent, but that the functional performance generally was better for this coated material. The use of an evaluation model to compare coated and laminated textiles demanded knowledge and experience of LCA to be used. Though with the right LCA knowledge, the combined methods of functional testing and environmental impact may lead to conclusions which would otherwise go unnoticed.

    Varumärkeslojalitet: en kvalitativ studie med inriktning på konsumenters kärlek och relationer till modevarumärken2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The fast evolvement of retail alternatives has resulted in an increasing competition in the fashion market which leaves the customer with a number of options to choose from. The change in loyalty toward brands means that companies have to face many challenges which involves distinguishing themselves from other companies. They have to offer the consumer value and thereby create an opportunity to maintain a long-term relationship with the consumer. In recent times it has become interesting to study consumers “love” towards brands and over time the concepts of brand love has emerged in research contexts. Brand love includes the level of passionate, emotional attachment that a satisfied consumer has for a particular brand. The study presents following theories: Customer-Based Brand Equity (CBBE), 11 Dimensions of Love Toward a Brand and The Brand Love prototype which manage brand loyalty and brand love. The authors has then used the earlier mentioned theories to create a new theoretical framework with six factors predicted for achieving brand love. The aim of the study is to examine in a consumer perspective which factors that create brand love and how brand-owned companies can create loyal consumers. Through qualitative, semi structured interviews and surveys the results indicates that four factors had a strong connection to brand love: Brand trust, Brand identification, Love relationship and Perceived and expected quality.

    Kroppspositivism: provdockor och modeller som visuellt kommunikationsverktyg för större storlekar2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study is to investigate how two Swedish fashion companies, Modefabriken and Klädverket, who claims to be body positive shows that in practice. The study is conducted within the subject Textile Management. The study is from a corporate perspective but has also generated some insights from a customer perspective. The data has been collected through primary and secondary data. The studies secondary data has generated a theoretical framework which includes a western society ideal of being skinny and the impact of media, the fashion industry and sizes, everyday models and edited models, body ideals and body activism. The primary data of the study has been collected through semi structured interviews, structured observations in store as well as analysis of four different product categories online. The collected data of the study has resulted in a modified communications model to investigate how companies uses mannequins in store and models online to show their range of sizes. Judith Butlers Queer theory is applied to see if companies have broken away from the skinny ideal. The result of the study shows that both Modefabriken and Klädverket use mannequins in two sizes. In their stores and online, they use one normative size and one size above the norm. Both shows garments with a size range from the smallest to the biggest size that the companies offer. The conclusion of the study is that Klädverket shows their body positive approach in greater extent than Modefabriken, mainly by using more plus sized models online but also bigger mannequins in store.

    Efficient social media marketing for sustainable fashion companies: Increasing interest and engagement on Instagram among millennial males by appealing to their values.2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The purpose of this paper is to identify how social media, specifically Instagram can be used to encourage interest among the millennial male for sustainable fashion products. The study contributes to give marketing insights and a broader understanding of the millennial male’s online behaviour, so that fashion companies within the sustainable sector of the industry can benefit from these when broadening their target market. The findings are to contribute within the field of textile management. Design/method/approach: The study has used a model based on millennial male values that were connected to visual picture content. The model illustrates how the millennial male is influenced by several factors and values, ultimately determining which type of visual social media content that results in the most engagement and interest for sustainable products. The methods included posting visual content on two different channels on the Instagram profile of a sustainable fashion company aimed at mainly millennial males. Different kinds of engagement with the content was measured in order to determine which type of content was the most successful at encouraging interest among millennial males towards sustainable fashion products. Findings: The findings of this research show that pictures posted on both Instagram feed and Instagram stories with social and aesthetic, as well as close-up and detail content, are likely to perform well and encourage interaction and engagement on Instagram. The findings also show that production related pictures are not generating an interest from the millennial male. Moreover, in order to reach a wider audience with the content shared on Instagram stories and feed content need to be used simultaneously. These findings suggest that companies can encourage male millennials to purchase sustainable products by appealing to their values. Practical implications: The findings by this study are valuable for sustainable fashion companies that are looking for ways to improve their reach and engagement with millennial males. The findings of this value can also benefit marketers to improve their marketing strategy on Instagram. Originality/value: The findings show that Instagram can be used to reach out to a wide spread of Instagram users with an interest of sustainable fashion. Moreover, the findings suggest that companies can encourage sustainable fashion consumption through appealing to the values of their target market, using social media content. Keywords: Sustainable fashion, Social media marketing, millennial male, marketing, Instagram content for marketing Paper type: Research paper

    Washing and drying reusable sanitary pads2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Period poverty is a problem mainly found in places characterized by poverty. The lack of means for women and girls to properly handle their menstruation is the essence of the problem. With a lack of both quantity and quality regarding water often being an issue in such places, the hygiene is a constant challenge. Two different kinds of sanitary products are used globally, disposable and reusable. The reusable ones are often being made of cotton or other absorbent materials. Regardless the material, reusable products need cleaning between the times of use, which could be a challenge when water is not always accessible. To have a reusable sanitary pad that efficiently can be cleaned with low amounts of resources is important, especially in impoverished places. Spacerpad is a reusable sanitary pad and a part of a project at the University of Borås. The aim for the project is to reduce period poverty and to educate women and girls in menstrual hygiene management. The pad is made of polyester which does not absorb blood or water, instead the pad merely contains the fluids. This thesis was conducted as a field study in Nairobi, Kenya. The study aimed to simulate a menstruation, in order to analyze the microbial activity in two different reusable sanitary pads, during as well as after menstruation. With the influences from interviews and resources found in Kibera (a slum in Nairobi) a simulation of five days was executed, with nutrient solution instead of menstrual blood. The Spacerpad and a cotton pad were exposed to the same procedures and the effects of washing and drying were studied. The microbial activity was measured with the help of dipslides, a growth medium. The results of this study show that both Spacerpad and the cotton pad could be carriers of heavy growth of bacteria. Increasing microbial activity throughout the simulation as the days went by, ended with a dividing result after a soap wash as the final washing procedure. The pad made of cotton still carried above slight growth, compared to Spacerpad that showed almost no activity after the final cleanse. Even though the microbial activity reached high levels during the simulation, the fact that the Spacerpad can be cleaned with limited resources could be reason enough to consider the Spacerpad as a sufficiently sanitary product in an impoverished place like Kibera.

    Are You Creating Socially Responsible Visual Communication?: An Exploratory Study of Fashion Companies’ External Social Responsibility on Instagram: A Marketer’s Perspective2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background: Following the development of digitalization and the emergence of social media a lot of attention has been drawn upon how these platforms are influencing the fashion industry and fashion marketing. As society is becoming more ethics and health conscious, fashion companies’ visual representations in social media are drawing more attention - who is represented and how are these representations portrayed. Previous research has shown that white and thin models are a recurrent over-representation in media, consumers through these see the ‘ideal’ or stereotypical body types or norms, and not an actual or full representation of society. The issue is, however, not that white or thin people are represented in media. The problem is how companies portray these representations and how the portrayals lead to the exclusion and misrepresentation of other groups in society.

    Purpose: The purpose of this study is to investigate the CSR practice of fashion companies regarding the body image representations in social media marketing communications, with specific focus on the marketer’s perspective.

    Methodology: For this study an exploratory cross-sectional case-study research design approach was applied. Four corporate cases of fashion companies were analyzed using data triangulation methods on the basis of content analysis and semi-structured interviews. First, case analysis of social media contents and interviews were conducted, followed by cross- sectional analysis to find out if fashion companies’ practiced social responsibility is aligned with the verbally expressed social responsibility.

    Findings: The findings of this study demonstrate that fashion companies consider external social responsibility as an important issue, however, a gap between the companies practiced social responsibility and verbally expressed social responsibility remains. The study shows that two of the companies’ practiced social responsibility on their Instagram channel is in alignment with their verbally expressed social responsibility, when it comes to representing diversity in terms of body size, ethnicity and skin color. However, when it comes to the representational conventions it was noted that all the companies are lacking in external responsibility due to the continuous signs of idealization and body-ism on all the companies’ Instagram channels. Conclusion: This study contributes to the research field regarding companies’ external social responsibility on Instagram. The findings provide companies and researchers with awareness of which representational conventions/key social aspects are currently lacking in corporate marketing activities and should become the focus for further improvement. Based on obtained results, a modified framework for image analysis and criteria for image/content creation are suggested. The framework and criteria can assist future researchers, help content creators and other practitioners to understand the complexity of external social responsibility and how to implement it in practice.

    On Textile Farming: Living Indoors2019Doctoral thesis, monograph (Other academic)
    Abstract [en]

    Horticultural practices are increasingly entering the private realm due to the popularity of urban gardening, indoor gardening systems, and architectural propositions to join living spaces for people and vegetable cultivation in order to promote more resilient and sustainable ways of living. While new research into symbiotic processes between living organisms and their ability to sense and reason triggers new works of art, culture, design, and architecture, the organisation of indoor plants remains mainly unaffected. This is due to the fact that many of the examples that aim to bring together people and plants in an architectural context are characterised by rigid materials and technical systems that separate people and plants from each other and feature relatively unnatural environments, compositions, and expressions. In proposing an alternative perspective on this, On Textile Farming explores textiles as flexible systems for integrating plant growth in textile materials. The collaboration with AB Ludvig Svensson, a developer and producer of textiles for interiors and greenhouses, involved a joint approach to the two distinct areas of climate screens and interior textiles. Through experimental methods, interactions between plants and textiles were explored using double-weave structures to integrate seeds and substrate. A methodological framework is proposed wherein the processes and materials of textile and spatial design open up for environmental parameters, e.g. changes in time, climate, and material behaviour. The design concepts ‘textile permeability’, ‘seasonal textiles’, and ‘textile climate’ describe the interactions between plants, textiles, and space, and can be seen as first steps towards an interior textile ecosystem in which spaces are composed of relationships between biotic and abiotic components, causing the natural and the artificial to intersect. ‘Spatial permeability’, ‘seasonal interiors’ and ‘spatial climates’ expand the three textile concepts towards space and describe interactions between different spatial qualities that were explored through autobiographical research; for this, an experimental house was built in a rural region of Sweden and lived in. In this context, textiles be-came flexible interfaces between the inside and the outside, guiding growth and melting into seasonal expressions that blurred nature and artifice.

    On Textile Farming: The Interior as an Ecosystem2019Conference paper (Refereed)
    Abstract [en]

    Alongside with smart materials, biomaterials become increasingly available to the field of textile design. This biological paradigm brings an alternative perspective to the ways in which textiles can be designed, present themselves, and can be dealt with. As biomaterials such as plants and bacteria thrive in symbiosis with their environment, their ecosystem consequently becomes disposable to the expressions of textiles and interior spaces. Here, textiles could take on the role of a mediator for ecosystem services, e.g. guiding the growth of crops, regulating indoor climates and supporting the decomposition of waste. This research aims to explore what the design of a ‘textile interior ecosystem’ would be like and discusses what the role of textiles as accommodating biological processes in relation to this system could be. By experimental research, ‘On Textile Farming’ explores the design of ‘textile interior ecosystem’ investigating e.g. growing crops, composting and fermenting in interior spaces in order to speculate how these biological principles could be translated into the design of textiles and how this would change the way we form interior spaces, live with them and understand them - as a community of living systems. By embedding biological agents e.g. plants and bacteria into interior fabrics, a biological perspective is added to their life-cycle. Here, the role of the textile is opened up towards a substrate for biological agents, a template for growth and a mediator in between all actors involved in the ‘textile interior ecosystem’. As a result, this research presents speculative scenarios which exemplify the extended life-cycle, illustrate the increase in interior diversity and forms of habitation using textiles, from an aesthetic and functional point of view. In a time in which the way we handle relationships to biotic and abiotic components is discussed and criticised, ‘On Textile Farming’ could open up a range of concepts unfamiliar to designing textiles and spaces, such as ‘Seasonal Interiors’, ’Multispecies Interplay’ and ‘Textile Hortitecture’.

    Enhanced Methane and Hydrogen production in Reverse Membrane Bioreactors via Syngas Fermentation2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    of waste treatment processes, such as the anaerobic digestion. This biochemical process converts organic substrates into biogas, with anaerobic microorganisms. However, some types of substrates have low bio-degradability due to its recalcitrance or the presence of inhibitors. This can be solved by the coupling of anaerobic digestion with gasification, a thermochemical process that can convert organic substrates into syngas (H2, CO, and CO2) regardless of the substrate´s degradability. Consequently, syngas can be converted into biogas and other fermentative products via anaerobic digestion, in a process known as syngas fermentation. In comparison to the catalytic conversion of syngas, syngas fermentation has several advantages such as lower sensitivity to CO/H2/CO2 ratio and to syngas contaminants as well as higher product specificity.

    The main goal of this thesis was to improve the syngas conversion rate into CH4 and H2 by addressing the cell washout, the cell inhibition by syngas contaminants, and the low gas-to-liquid mass transfer, which are major challenges in syngas fermentation. For this purpose, a reverse membrane bioreactor, containing a mixed culture encased in membranes, was used in various set ups. The membranes were used in order to retain the cells inside the bioreactors, to protect the cells against inhibitors, and to improve the gas holdup and gas-to-cell contact by decreasing the rise velocity of syngas bubbles. As evident from the results, the cell washout was successfully tackled during a continuous experiment that lasted 154 days. In addition, membrane bioreactors fed with the syngas contaminants, toluene and naphthalene, achieved approximately 92% and 15% higher CH4 production rate, respectively, compared with the free cell bioreactors. In order to improve the gas holdup and consequently the gas-to-liquid mass transfer of syngas, a floating membrane bed bioreactor was set up. This bioreactor contained membrane sachets, filled with inoculum that formed a packed floating membrane bed and achieved an increase of 38% and 28% for the conversion rate of H2 and CO, respectively. Furthermore, the addition of a mixture of heavy metals improved the production rates and yields during the syngas conversion into fermentative H2.

    The drama in the hybrid OR: video observations of work processes and staff collaboration during endovascular aortic repair.2019In: Journal of Multidisciplinary Healthcare, ISSN 1178-2390, E-ISSN 1178-2390, Vol. 12, p. 453-464Article in journal (Refereed)
    Abstract [en]

    Introduction: A hybrid operating room (OR) is a surgical OR with integrated imaging equipment and the possibility to serve both open surgery and image-guided interventions.

    Aim: This study aimed to investigate the work processes and types of collaboration in a hybrid OR during endovascular aortic repair (EVAR).

    Methods: Data consisted of video recordings from nine procedures, with a total recording time of 48 hrs 39 mins. The procedures were divided into four episodes (Acts). A qualitative cross-case analysis was conducted, resulting in a typical case. The type of collaboration during specific tasks was discussed and determined based on Thylefors´ team typology.

    Results: An extensive amount of safety activities occurred in the preparation phase (Acts 1 and 2), involving a number of staff categories. After the skin incision (Act 3), the main activities were performed by fewer staff categories, while some persons had a standby position and there were persons who were not at all involved in the procedure.

    Discussion: The different specialist staff in the hybrid OR worked through different types of collaboration: multi-, inter- and transprofessional. The level of needed collaboration depended on the activity performed, but it was largely multiprofessional and took place largely in separate groups of specialties: anesthesiology, surgery and radiology. Waiting time and overlapping tasks indicate that the procedures could be more efficient and safe for the patient.

    Conclusion: This study highlights that the three expertise specialties were required for safe treatment in the hybrid OR, but the extent of interprofessional activities was limited. Our results provide a basis for the development of more effective procedures with closer and more efficient interprofessional collaboration and reduction of overlapping roles. Considerable waiting times, traffic flow and presence of people who were not involved in the patient care are areas of further investigation.

    Team composition and staff roles in a hybrid operating room: A prospective study using video observations.2019In: Nursing Open, E-ISSN 2054-1058, Vol. 6, no 3, p. 1245-1253Article in journal (Refereed)
    Abstract [en]

    Aim: The aim of the study was to evaluate team composition and staff roles in a hybrid operating room during endovascular aortic repairs.

    Design: Quantitative descriptive design.

    Methods: Nine endovascular aortic repairs procedures were video-recorded between December 2014 and September 2015. The data analysis involved examining the work process, number of people in the room and categories of staff and their involvement in the procedure.

    Results: The procedures were divided into four phases. The hybrid operating room was most crowded in phase 3 when the skin wound was open. Some staff categories were in the room for the entire procedure even if they were not actively involved. The largest number of people simultaneously in the room was 14.

    Household Waste Sorting and Engagement in Everyday Life Occupations After Migration—A Scoping Review2019In: Sustainability, ISSN 2071-1050, E-ISSN 2071-1050, Vol. 11, no 17, article id 4701Article in journal (Refereed)
    Abstract [en]

    The aim of this scoping review was to gain an overview of the current state of the literature on the engagement in waste sorting post migration from an occupational perspective, in the light of two aspects sustainability efforts currently face: Increased human migration and environmental degradation. Both the resource recovery and occupational science literature were reviewed and analyzed. However, despite the current lack on studies on how migrants’ transition into waste sorting schemes at the household level, this scoping review was able to provide a broad picture of the engagement in daily activities that support sustainability, such as household waste sorting. Given the current initiatives to develop efficient resource recovery from waste, such knowledge contributes to efforts to engage households with different cultures and experiences in waste sorting. The results highlight the importance of future research to better understand how people who are new to waste management schemes experience these, and study the way that engagement in waste sorting shifts and transforms. This is because providing such knowledge can contribute to raising awareness of the environmental impact of waste sorting, and inform policies aimed at sustainable waste management.

    Young People’s Life and Schooling in Rural Areas2019Book (Refereed)
    Abstract [en]

    Roberts and Green’s understanding of the need to broaden the social justice agenda in education research to include rural areas and more plural forms of capital in them than the purely economic form has been of value in the production of this book and has encouraged an extended and deepened focus on space, place, and social justice in our investigations. The first chapter sets the scene for this by presenting the research field, and some core questions for the research project relating to the dominance of urban studies in education (and social sciences more generally) and the silence on rural conditions and problems. The chapter also presents the research project and its theory, methodology and data production to provide a coherent background and frame for the thematic chapters so they can focus on their findings and discussions.  The following empirical chapters then focus on prominent themes emerging from the fieldwork and address both rural schooling and youth’s rural lives more generally. This is in line with the chosen theoretical understanding of place as central, requiring that education, as other institutions, is analysed in its socio-spatial context.  

     

    Chapter 2 focuses on place and draws especially on youth’s presentations of the researched places. It includes sub-themes concerned with the various images of places and of strategies to maintain place relations. In this respect there are similiarities, but also differences between the different ruralities. Chapter 3  moves the analyses to the different schools and their relations to the surrounding communities. Central to this, is the presentation of the places and their relations (conflicts, values, silences) found in teaching and their relations to other places. The analyses point to some differences between ruralities in this respect, with schools in the sparsely populated areas more likely to explicitly position themselves in the rural local context, and valorise the rural positively in education exchanges, content and interaction compared to the schools in small (de)industrialised communities, with positive effects on young people’s understandings. Chapter 4 focuses on young people’s views of their future options and their dreams of further education and work in relation to the local material conditions of the rural places, such as the labour markets. Gendered and classed characteristics are found to be of particular importance in the process of shaping the young people’s ideas of future careers, both limiting and broadening their views. Chapter 5 emanates from the chosen theoretical framework of the project that emphasises place as constantly in process and reshaped. In this respect, migration poses as a special challenge and an option for sparsely populated and de-populated areas. In the researched sites, we note an influx in recent years of refugees – particularly apparent with the unforeseen inflow of refugees from Syria during the fieldwork - but also of labour migrant from Northern Europe. Taking this as a starting point, this chapter analyses issues concerned with various groups’ understandings of place and its relations.  

     

    Chapter 6 continues with a focused analysis. It  addresses themes of gender and class. It presents previous research on gender and class in relation to rural youth and education and from this, moves to present some of the main findings from our research. These indicate less stereotyped gender relations than in much previous research, but still an overall trend towards masculine activities and values.  Chapter 7 focuses on relations between rural and urban areas, their respective conditions, problems and challenges. This is a central question for the book and this chapter aims to present a synthesising discussion. It draws on previous research of urban and rural youth and their schooling, and explores the under-researched rural dimension by use of our data to discuss rural understandings and responses to socio-spatial issues. The final chapter (chapter 8) draws together central themes from the previous chapters. These are concerned with various aspects of social structures, social relations, their implications for social inclusion, and how these are addressed in school and teaching. It also returns to the initial questions posed in the first chapters about rural – urban relations, metrocentricity and marginalisation....

    Introduction2019In: Young People’s Life and Schooling in Rural Areas / [ed] Dennis Beach and Elisabet Öhrn, London: Tufnell Press, 2019Chapter in book (Refereed)
    Abstract [en]

    A key motivation for the research presented in this book is that urban studies dominate contemporary educational research, as highlighted for example by Hargreaves, Kvalsund & Galton (2009). Consequently,  knowledge of young people's marginalisation and participation in education and the wider society is based on observations of life in limited geographical/social contexts. The predominant metrocentricity leads to the neglect of needs that are not present, or readily apparent, in cities (Farrugia, 2014, p. 293) and underestimation of problems faced by rural youth. This is despite findings that it is mainly young people from outside metropolitan regions who express a lack of involvement in Swedish society and a dearth of confidence in both government and parliament (e.g. Swedish National Board for Youth Affairs, 2010). Thus, to obtain a more representative picture of young people’s situations and education we need to explore rural youths and their schooling more broadly and deeply....

    Surface modification of polyester fabric using plasma-dendrimer for robust immobilization of glucose oxidase enzyme2019In: Scientific Reports, ISSN 2045-2322, E-ISSN 2045-2322, article id 15730Article in journal (Refereed)
    Abstract [en]

    Robust immobilization of glucose oxidase (GOx) enzyme was achieved on poly(ethylene terephthalate) nonwoven fabric (PN) after integration of favourable surface functional groups through plasma treatments [atmospheric pressure-AP or cold remote plasma-CRP (N2 + O2)] and/or chemical grafting of hyperbranched dendrimers [poly-(ethylene glycol)-OH or poly-(amidoamine)]. Absorption, stability, catalytic behavior of immobilized enzymes and reusability of resultant fibrous bio-catalysts were comparatively studied. Full characterization of PN before and after respective modifications was carried out by various analytical, instrumental and arithmetic techniques. Results showed that modified polyester having amine terminal functional groups pledged better surface property providing up to 31% enzyme loading, and 81% active immobilized enzymes. The activity of the enzyme was measured in terms of interaction aptitude of GOx in a given time to produce hydrogen peroxide using colorimetric assay. The immobilized GOx retained 50% of its original activity after being reused six (06) times and exhibited improved stability compared with the free enzyme in relation to temperature. The reaction kinetics, loading efficiency, leaching, and reusability analysis of enzyme allowed drawing a parallel to the type of organic moiety integrated during GOx immobilization. In addition, resultant fibrous bio-catalysts showed substantial antibacterial activity against pathogenic bacteria strains (Staphylococcus epidermidis and Escherichia coli) in the presence of oxygen and glucose. These results are of great importance because they provide proof-of-concept for robust immobilization of enzymes on surface-modified fibrous polyester fabric for potential bio-industrial applications.

    En bild är inte bara en bild: En kvalitativ studie om bildens betydelse för förskolebarns språkutveckling2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund

    Med hjälp av bilder kan barns utveckling av verbalt språk stödjas. Genom att pedagoger och barn samlas kring bilder i verksamheten kan diskussioner uppkomma vilket kan leda till att barnets verbala språk utvecklas. Vår studie grundar sig i tidigare forskning, litteratur och styrdokument som tar upp bildens betydelse för förskolebarns språkutveckling. Vi kommer att presentera tidigare forskning utifrån estetiska lärprocesser samt användning av bilder i språkutvecklande aktiviteter.

    Syfte

    Vi vill med detta arbete undersöka bildens betydelse när det gäller användning av bilder i förskoleverksamheten och huruvida bilder förfaller kunna stödja förskolebarns språkutveckling. Vill vi även undersöka hur språkutvecklande aktiviteter kan se ut under barns olika åldrar med och utan användning av bilder.

    Metod

    Vårt arbete är en kvalitativ studie där vi använt intervju samt observation som metod. Studien undersöker användningen av bilder och hur bilder kan användas som stöd för barn. Vidare använder vi observation av fri lek och aktivitet som metod för att kunna studera språkanvändning i olika åldrar i relation till bildanvändning. Studien har gjorts på en förskola i mellersta Sverige.

    Resultat

    Resultatet visar att pedagogerna använder sig av bilder i kommunikationen med barnen. Barnen kan göra sig förstådda med hjälp av bilder när det uppstår en frustration som beror på att de inte blir förstådda. Förskollärarna i studien samtalar mycket om deras roll som medvetna pedagoger gällande hur bilder kan användas som ett stöd för det enskilda barnet. Vår studie visade att språkutvecklande aktiviteter skiljer sig åt mellan olika åldrar. De yngre barnen använder också mer icke verbal kommunikation, än de äldre barnen. Ytterligare resultat var att användning av bilder leder till ökad användning av verbalt språk.

    Samverkan mellan skola och fritids: En studie om samverkan mellan verksamheterna i Borås Stad.2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    För sex år sedan tog jag examen från lärarutbildningen vid Högskolan i Borås och under min utbildning hade jag fått många tips och idéer på hur klasslärare och fritidslärare kunde dela upp undervisningen och ansvara för olika delar av undervisningen beroende på kompetens och intresse. När jag kom ut i arbetslivet var det inte den verkligheten jag mötte. Under dessa år i arbetslivet har jag inte varit med om att samverkan mellan verksamheterna har fungerat som jag lärde mig på högskolan men å andra sidan har jag inte varit i fritidshemsverksamheten under några år heller. Därför är jag intresserad av att ta reda på hur samverkan mellan verksamheterna fungerar i Borås Stad idag.

    Studiens syfte är att ta reda på hur det ser ut med samverkan mellan skola och fritidshem i de kommunala skolorna i Borås Stad. Det vill säga undersöka om rektorerna ute på skolorna tar det förväntade ansvaret som står i läroplanen, se om verksamheterna samverkar om utbildningsinnehåll, om verksamheterna delar med sig av kunskaper och erfarenheter gentemot varandras verksamheter och om kompetensen ute på skolorna tas till vara.

    Studien är en kvantitativ studie med avsikt att låta hela populationen vara med och svara. Datainsamlingen gjordes med hjälp av en webbenkät som skapades med Google Forms och totalt besvarades av 137 personer av totalt 470 personer som fått den skickad till sig. Innan enkätens länk spreds inom populationen genomfördes en pilotstudie på tio personer som fick komma med återkoppling på frågorna.

    Resultatet av studien visar att lärarna i Borås Stad generellt har mindre än 30 minuter schemalagd tid i veckan för att planera samverkansaktiviteter och mindre än 30 minuter i veckan schemalagt för att genomföra dem. Över lag samverkar lärarna i de olika verksamheterna noll gånger i veckan om innehållet i verksamheterna för att tiden istället används till information, att prata om elever som befinner sig i svårigheter socialt och om rastvärdskap. De allra flesta upplever att rektorn är den som initierar samverkan på arbetsplatsen och övervägande av de svarande upplever att rektorn tar sitt ansvar och lever upp till vad som står i styrdokumenten. När eleverna ska byta lärare eller avdelning brukar en överlämning av information ske. Studien visar att lärarkategorierna tenderar att sköta överlämningen inom samma lärarkategori och inte ha med andra verksamheter vid överlämning. Fritidslärarnas huvuduppdrag ligger innan- och efter skoltid men arbetsuppgifterna under skoldagen varierar. Fritidslärarna används först och främst som klassresurs eller resurs för enskild elev men har även uppdrag som rastaktivitetsansvariga.

    Rastverksamhet: En studie om förebyggande konflikthantering och konfliktlösning i grundskolan2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Följande studie syftar till att belysa hur viktigt det är med rastverksamhet på skolor och hur skolor kan använda sig av rastverksamheten till att förebygga konflikter, öka gemenskapen och bidra till ett hälsosammare liv för barnen. Studiens syfte är att få en inblick i fritidslärarnas arbetssätt, få syn på hur rastverksamheten organiseras och fritidslärarnas sätt att arbeta med konflikthantering. Frågeställningarna i studien är: Hur beskriver fritidslärarna den organiserade rastverksamhetens betydelse för elevernas trivsel, hur uttrycker fritidslärarna att de arbetar med organiserad rastverksamhet samt på vilket sätt kan fritidshemmets personal skapa en aktiv rastverksamhet och förebygga eventuella konflikter under rasterna.

    Kvalitativa semistrukturerade intervjuer användes som metod. Detta gjorde att relevant data kunde samlas in och bearbetas så att jag kunde svara på mina frågeställningar. Fem intervjuer har genomförts på tre olika avdelningar på en skola. Vidare har teorierna sociokulturellt perspektiv, Cohens konfliktpyramid och lekteorier använts i studien. Jag har utgått från tidigare forskning om rastverksamhet och konflikthantering för att sätta in fritidslärarnas tankar i ett sammanhang i resultatet och analysen. Informanterna klargör att rastverksamheten minskar konflikter bland eleverna, och inkluderar också barn med sociala svårigheter. I studiens resultat framkommer att alla fritidslärare som medverkat i studien anser att det är viktigt med både den organiserade rastverksamheten och den fria rasten.

    Normkritiska barnböcker: En studie om könsmönster i barnlitteratur2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund

    Denna undersökning grundar sig på tidigare forskning samt litteratur som behandlar den ojämställdhet som förekommer när det gäller skildringen av manliga och kvinnliga karaktärer i barnlitteratur.

    Syfte

    Syftet med arbetet är att undersöka två normkritiska bilderböcker med fokus på att granska och analysera om de bryter mot könsroller och i så fall hur. Denna studie är en kvalitativ textanalys där bilderböckerna har analyserats, för att se vilka mönster som framträder när det gäller könsnormer.

    Resultat

    Resultatet av studien visar att de båda barnböckerna delvis lyckas förmedla ett normkritiskt förhållningssätt när det kommer till hur karaktärerna presenteras i böckerna. Det råder ett dubbelt budskap i de båda böckerna, vilket leder till att man som läsare kan misstolka skildringen av karaktärerna som presenteras i respektive barnbok. Studien påpekar att pedagoger görs medvetna om förlegade könsmönster i barnböcker samt att kritisk granska den barnlitteratur som erbjuds under lässituationerna med barnen för att på så sätt utmana barns idéer om könsnormer.

    Garment Sharing Events: The Perspective of Organisers and Participants2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Different social, environmental and economical aspects indicate the current need for sustainability and build the imperative for a change in the fashion industry from the prevailing “take-make-dispose” consumption habit to more circular practices, which minimise the input of resources. According to research, the most direct way to capture value and design out waste and pollution in the textile system lays therewith in increasing the number of times a garment is worn. Therefore, the key challenge is to subvert the habit that garments are perceived as disposable and to increase their utilisation.

    Purpose: The purpose of this thesis is to investigate how sharing events influence the use phase of garments through the perspective of organisers and participants of such events.

    Method: The study implemented a qualitative research nature and followed thereby an exploratory research design and strategy. Through semi-structured interviews, event organisers of different organisations with a well-founded experience in sharing events - staged in a Circular Fashion environment - provided their insights on the influence sharing events obtain regarding the use phase of garments. The research strategy supplemented the theories and empirical data with the insights of participants of a sharing event through self-completion questionnaires.

    Conclusion: Besides their practical ability to pass on garments to various users, sharing events are indicated to prolong the garment usage by promoting a possible change in the consumer’s mindset. Doing so, different aspects connected to Event Management, -Strategy as well as additional offers and activities, besides swapping, are facilitating. As the research outcome hints, the sharing event model, as one of the simplest forms of collaborative garment consumption, is indicated to influence the usage by enabling a change from garment consumer to user.

    Generation Z och trovärdighet: En undersökning av generation Z’s uppfattning av trovärdig grön modemarknadsföring2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this qualitative study is to investigate generation Z’s perception of crediblegreen marketing from the fashion industry, as well as understand which factors affect thecredibility of what is communicated. Furthermore, we look at how the green marketing couldbe designed in order to be perceived as credible as possible by generation Z.The data was collected through semi-structured interviews. Our population was generation Z,which constitutes an age span from 1995 to 2010 according to the literature, but to obtainmeaningful data we chose to make a delimitation to individuals born between 1995 and 2000.This resulted in seven interviews that gave us the necessary data which was then transcribedand analyzed. Through thematic coding, common themes and patterns were identified fromthe respondents.The result of the study shows that our respondents consider that there is a lack of bothknowledge about sustainable fashion and exposure to green marketing. Fashion companiesshould communicate information that leads to increased consumer knowledge ofenvironmental sustainability in order to create credibility. Another important factor toincrease their credibility is for fashion companies to be transparent in their green marketing.To include facts, numbers, third party certification (environmental labeling) and theexplanation of processes positively affects the perceived credibility. In the absence oftransparency generation Z, including our respondents, suspect greenwashing. The greenmarketing should contain short texts with explanatory and easily understandable concepts incombination with films or pictures. The product should have a central role in marketing inorder for the consumer to see what they pay for. Explaining why the products areenvironmentally sustainable, rather than simply stating that they are, increases the credibilityof the green fashion marketing.

    Girl Get Dressed/Ready to Wear: Designing activities of getting dressed2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This body of work operates at the border between fashion and performance, with the intention to explore the performativity of body, inrelation to forms of dress. The work presented in this thesis sets out to examine the ways the performed act of making may inform theoutcome through designing new activities of getting dressed as producers for dress, while questioning the static systems of makingdress that develops form mainly with an approximation of a bodily form.The work is not about dance, it is not about theatre, it is not about choreography. This work is about the activity of getting dressed andwhat potential knowledge in dress that may be extracted from simply shifting the established order of the relationship between bodyand dress. However, from a methodological point of view, the work is developed through choreography and performance in relation toarranged space as tools to design the activities, and these may well be viewed as a danced or theatrical and dramaturgical play of body,motion, material and dress.These aspects are part of the outcome that suggests not only new formal relationships between body and dress and new methods formaking dress, but also new ways of looking at, and consuming the art of dress.

    En omprofilering av ett väletablerat varumärke genom påverkarmarknadsföring: En fallstudie om Baum und Pferdgarten A/S2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of the study is to analyse, from a marketing perspective, how a wellestablished premium brand's rebranding process can interact with the phenomenon called influencer marketing. The analysis will shed light on how such a united action can bedesigned to create competitiveness on the market, as well as examine its possibilities and risks.

    Methodology: The study is of qualitative character and was executed with an inductiveapproach through a case study. The primary data was collected from six semi-structuredinterviews and was supplemented, where necessary, by secondary data. The empirical datawas analysed by the help of thematisation in order to reach a conclusion.

    Theoretical perspectives: The theoretical perspective of the study is based on rebranding andits connection to brand identity. It explains how a company strategically should design the process, and how it will affect the internal business. Furthermore, the study is also based on atheoretical gate about how digital channels and influencer marketing can affect consumerbehaviour and their formation of perception.

    Empirical foundation: The choice of study object fell on Baum und Pferdgarten A/S. Thecompany is a well-established fashion house in Denmark, and has been active on the marketfor 20 years. In the empirical data section, primary and secondary data are presented in detail. The focus lies on analysing the company's rebranding process and how they through this strategically plan to work with social media and influencer marketing.

    Conclusion: The study concludes several approaches where both possibilities and risks couldbe identified, when rebranding through influencer marketing. The conclusions were gathered in four categories, which summarise; a marketing strategy that generates measurable and traceable results, increased diversity within the brand's target group, possibilities in an added value around the relationship between company and influencer, and the possibility to work with unpaid sponsorships. When developing influencer marketing as a main strategy, the combination of an continuous analytical work around influencers and a deeper knowledge of the company's target group was highlighted. Furthermore, a limitation within rebranding through influencer marketing was also identified in consumers increasing demand for high variation in image material as well as a faster type of communication on social mediaplatforms and other digital channels.

    Color performance, durability and handle of inkjet-printed and UV-cured photochromic textiles for multi-colored applications2019In: Fibers And Polymers, ISSN 1229-9197, E-ISSN 1875-0052, Vol. 20Article in journal (Refereed)
    Abstract [en]

    The development and design of novel functional and smart textile materials such as textile sensors and multicolored systems based on photochromic dyes necessitate controls of color intensities, switching speeds, and material durability. Precise control and synchronization of dye kinetics are important for multi-colored photochromic applications especially. However, durability towards abrasion and washing should not be compromised on if we aim to design reliable future textile products. In this study, two different commercial photochromic dyes — a naphthopyran and a spirooxazine-based dye — have been applied on PET fabric by inkjet printing and UV-LED curing. The photochromic textiles’ color behavior, fastness to abrasion and washing, and handle are evaluated using spectrophotometry, scanning electron microscopy, and Kawabata evaluation system. Despite a decrease in color performance after washing, the photochromic inkjet print is effective and barely influences the textile structure. Reduced rigidity of the host matrix promoted higher color yields and faster dye kinetics, but also improved durability towards abrasion and washing. In order to synchronize kinetics of the different dye types for multi-colored applications, distinct curing conditions are preferable, which, however, result in varying print durability. In the design of multi-colored photochromic textiles, dye kinetics, and durability have to be balanced.

    Efficiency Improvements in Waste-to-Energy Combustion Processes: Method Development and Evaluation2019Doctoral thesis, monograph (Other academic)
    Abstract [en]

    is the energy recovery method. The electrical efficiency of this technology, however, is generally low when compared with other solid fuel-fired combustion plants as a result of low steam properties. Furthermore, there is lack of efficient methods to evaluate the performance of this system. The energy method, normally used, does not account for exergy destruction due to entropy generated within the system.In this thesis, an exergy model for estimating the maximum available energy in a municipal solid waste and a modified exergy-based method for calculating the improvement potential in a waste-to-energy plant are developed. The exergy model was obtained from estimations of the higher heating value and standard entropy of municipal solid waste from the elemental compositions of the waste using statistical analysis. The improvement potential was derived by comparing the exergy destruction of the real process with its corresponding theoretical process. It was applied in a solid-waste fired heat and power plant to investigate possible improvements in the system as well as the cost of the improvements. The different improvement modifications considered include the re-arrangement of air heaters, the introduction of a reheater, flue gas condensation and an integrated gasification-combustion process. Modelling, simulation and cost estimations were performed with the Aspen Plus software.

    The results showed that the present proposed exergy model was more accurate than the previous models for estimating the maximum available energy in waste material, as the proposed model incorporates all the major elemental constituents as well as the physical composition of the solid waste. Moreover, the results obtained from the higher heating value model show a good correlation with the values measured, and are comparable with other recent and previous models. Furthermore, it was found that 64 % of the total exergy destruction in the process plant investigated can be reduced, while the boiler was identified as a component with the greatest potential for making improvements to the plant. Although the integrated gasification-combustion technology with flue gas condensation has the highest exergy efficiency, its higher capital cost exceeds all other alternatives. The improvement modifications with flue gas condensation not only provide the highest heat production but also the highest net present value. This indicates that flue gas condensation has a significant impact on the overall income generated by waste-to-energy combined heat and power industries.

    Immersed flat-sheet membrane bioreactors for lignocellulosic bioethanol production2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The rising awareness of the environmental, economic and socio-political impacts of over-exploitation of fossil-based fuel and energy sources, have motivated the transition toward more sustainable and renewable energy sources. Lignocellulosic materials (e.g. agricultural residues) are potential candidates for sustainable bioethanol production that contributes to the replacement of fossil fuels. However, to have an economically feasible and commercialized process, issues associated with lignocellulosic bioethanol production in upstream, fermentation and downstream processing stages should be alleviated. Membrane bioreactors with their great capabilities in semi-selective separation are promising options for making a breakthrough in lignocellulosic biorefinery processes. Therefore, in this thesis, different membrane modules and immersed membrane bioreactors (iMBRs) set-ups were developed and applied to take advantage of this long-matured water and wastewater treatment technique in remediation of challenges in the lignocellulosic bioethanol production.

    Thus, In order to intensify and optimize the lignocellulosic bioethanol production process, pressure-driven flat sheet microfiltration iMBRs were integrated into different processing stages. The application of a continuous iMBR led to a high ethanol productivity and yield (83% of theoretical yield) at high suspended solid content (up to 20% w/v) of wheat straw hydrolysate, and successful bacterial contamination separation from yeast (up to 93% removal). Moreover, using double-staged iMBRs for continuous hydrolysis-filtration and co-fermentation-filtration led to an effective separation of lignin-rich solids (up to 70% lignin) and sugar streams from the hydrolysate, and yeast cells from the fermentation product stream, stable long-term filtration performance (up to 264 h) at filtration flux of 21.9 l.m-2.h-1. In this thesis, filtration performance was thoroughly investigated, and effective physical fouling preventive approaches were applied to guarantee continuous bioprocessing. In addition, in order to remediate issues related to high content of inhibitors and presence of sequentially-fermented hexose and pentose saccharides in lignocellulosic fermentation, the cell-confinement approach of reverse membrane bioreactor (rMBR), which merges the benefits of iMBRs and cell encapsulation techniques, was introduced and applied in this thesis. It was observed that the high local cell density and diffusion-based mass transfer in the rMBR promoted co-utilization of sugars, and boosted cell furfural detoxification at concentrations of up to 16 g.l-1. Moreover, considering the needs of rMBR processes for cell recirculation, membrane envelope degassing, and media conditioning, a novel membrane module was designed, developed, and patented in this thesis work.

    Feasibility of Fashion Remanufacturing: Organizing fashion value chains for circularity through remanufacturing (including redesign)2018Report (Refereed)
    Abstract [en]

    Despite the increasing need of remanufacturing in fashion industry for leading towards dematerialization, higher revalue addition, possibility to generate highest profit margin, along with create more employment in the industry, it is still practiced on a very small scale. A net-positive environmental impact however, can only be made through remanufacturing with higher scale. However research investigations on this matter are insufficient and knowledge of the practices on new value chain models, associated processes, and designers’ approach to the product development process is still limited.

    The general aim of this study is to investigate how remanufacturing can be made feasible industrially for sustainable competitiveness in the fashion industry.

    This feasibility study was conducted by Re:Textile group in collaboration with several Swedish players, e.g. fashion branded retailers, local textile and apparel manufacturers, and charities. 3 participatory action projects were developed between 2017-2018 in order to elucidate the different possibilities of organizing remanufacturing in fashion industry context, and check the viability of these options. 3 different fashion remanufacturing models were considered to be interesting via literature review, and were planned for further exploration. These were: scaled remanufacturing, distributed redesign and PSS redesign-as-a-service.

    The study identifies the key decision making variables in each of these models, the critical success factors and also in connection assessing the feasibility of each model by constructing various scenarios.
