    Implementation of Marketing Strategies Practiced by Western and Eastern European Fashion Brands: H&M and Reserved Case2015Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The purpose of this thesis is to examine diverse marketing strategies used by Western and Eastern European originated fashion brands based on H&M and Reserved cases as well as which of them are the most appealing to Polish students. Additional aspect of the diploma is to research if there are some evident differences or similarities in implementing these tactics. Method: The study implemented both qualitative and quantitative research. Data collection was based on two types of data, secondary and the primary one. The secondary data was derived from fashion marketing literature, scholar articles and fashion blogs. The primary data included a semi- structured interview with Reserved's assistant marketing manager and questionnaires provided to Polish students. Subsequently, systematic combining was applied, that can be described as nonlinear process of matching theory and reality. Conclusion: Fashion marketing tools implemented in both companies can be assessed as quite similar with no evident difference, yet they differ from each other in certain aspects. In both cases advertising and sales promotion are the most employed tactics. Both companies are seen as international ones, though H&M seems to follow more fashion oriented approach engaging in fashion shows or providing their customers with their own glossy magazine. The study also revealed that advertising activities and sales promotion seem to be the most appealing marketing techniques for the respondents. In addition social media proved to be an essential element to build a connection with consumers. However, this communication channel is often neglected or not utilized to its' full potential.

    Optimering av St1s anläggning med integrering: Vägen till en hållbar utveckling2016Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Många företag och industrier arbetar idag ständigt med att utveckla mindre miljöbelastande sätt att arbeta på, det beror på hårdare lagar och regler än tidigare angående utsläpp till miljön. Företag inventerar mycket resurser på ny forskning och ta fram nya metoder, allt för att bidra till en hållbar utveckling. St1 är ett av de företagen som vill vara med i arbetet för en hållbar utveckling och främst av förnybara bränslen. St1 har utvecklat en ny metod för framställning av etanol utav restråvaror från livsmedelsindustrin. Det bildas även drank som är en biprodukt som man kör ut till lantbruk för att använda som djurfoder eller vid produktion av biogas. Metoden benämns som Etanolix och den nya anläggningen på St1 Refinery AB är den senaste som fått namnet Etanolix 2.0. Syftet med rapporten är att visa hur integrering kan göras med en ny anläggning tillsammas med en redan befintlig och hur man kan ta till vara på outnyttjade resurser. I rapporten beskrivs de olika hjälpsystem som är integrerade med Etanolix 2.0 som processvatten, kvävgas samt ånga och kondensat. Det beskrivs också hur första året med Etanolix 2.0 i drift har gått och vad som varit utmaningarna vid uppstarten. Slutsatsen vi kom fram till är att Etanolix metoden bidrar till en hållbar utveckling och steget närmare att skapa framtida förnybara bränslen. Projekt Etanolix 2.0 är fortfarande i uppstartningsfasen och behöver ytterligare utveckling innan optimal produktion av etanol kan ske.

    Energianalys av äldre flerbostadshus: Kvarter Kommissionären i Mariestad2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This bachelor thesis does an energy analysis of six multi-family houses. The properties are located in the housing block called Kommissionären and are owned by Mariehus AB. This company manages and develops renting apartments and make sure that their residents feel good in their properties. The purpose of this diploma work is to help the company analyze their properties from both an energy and a building technical point of view. The purpose is to study energy usages and energy losses. This proposes a couple of steps to reduce and improve the energy efficiency in the houses. The six houses were built between in the 1940´-s and the 1960’-s and are in need of refurbishment to become more energy efficient. The reason is large energy losses through different parts of climate shell. Regarding ventilation, a lot of energy is lost annually which, through simple measures, can be saved. In summary, the six multi-family houses are in fairly good condition considering their age, but that there is still potential for saving energy due to the high energy losses.

    Expressing and Sensing Hybrid Materiality: Voluminous Interactive Architectural Substance2019In: TEI '19 Proceedings of the Thirteenth International Conference on Tangible, Embedded, and Embodied Interaction: Pages 483-489, Tempe, Arizona, USA — March 17 - 20, 2019, ACM New York, NY, USA ©2019, 2019Conference paper (Refereed)
    Abstract [en]

    In this architectural research exploration, we challenge the notion of an interactive architectural surface as single-layered, two-dimensional interaction interface. Instead, we propose the notion of Interactive Voluminous Substance, which moves the interaction experience into four dimensions, shifting it from far-field, proximity-based interaction to a near-field, tactile one. We present four features of architectural expression that could potentially sustain the embodiment of this Substance: spatial positioning, geometry, expression, hybrid material composition and interaction design. If the future architectural interiors and exteriors are made from Voluminous Architectural Substance, how will it be to dwell with them? We propose two physical prototypes and two interaction stories as speculative objects probing this question.

    The Concept of Mental Models in Co Design2012Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    This study will provide an overview of mental models in teams and the significance of this particular concept for design teams. Researchers have applied the concept of mental models to understand how people perform tasks on the basis of their knowledge, assumptions, predictions and expectation. An overview is also provided on the relation between performance and mental models and their effect on stakeholders. The implications for design field are discussed. Through the study of two organizations in the same industry, the teams are studied in detail for each of these companies and hence leading to the study of mental models of stakeholders. Through the use of interviews, a detailed analysis is done on the team mental models. The mental models of stack holders and their influence on different aspects of company and team performance are discussed in detail. The methodology for the study of mental models is also proposed in the study. The findings are based on the data collected through interviews in both the organizations. The empirical study is designed in such a way that it investigates further the validity of theoretical concepts. Warid is a major telecommunication brand in Pakistan that provides services in all the regions of the country. Ufone is also a well-known telecommunication brand, known for its innovative and creative TVCs (TV commercial). Interviews with the marketing and sales officials of both these organizations provided an insight into the teams behind their advertising/marketing campaigns and the affect of stakeholders’ mental models on the performance and sales of the companies. The comparative analysis between the theoretical and empirical studies suggests that the quality of mental models is affected by diversity in the team, education and experience of the team members. This may be brought in for future research to further verify the effectiveness of mental models for design teams and eventually the whole organization. Finally the implications of our findings are discussed.

    What improves the user-designer communication in co-design?2013Independent thesis Advanced level (degree of Master (Two Years))Student thesis
    Abstract [en]

    Today’s business and IT systems have strongly focused on effective communication. The communication based on poor foundation might create huge communication problems for the system designer and user. These communication problems have a severe impact on the efficiency of information system and most importantly when it comes to the building of a new information system through co design process. For any business organization, IT plays a huge role these days. Although this is not given much emphasis sometimes, it is important to understand that the use of IT in business cannot be taken for granted because it is viewed as part of business organization these days. The business needs to continuously make investments in their IT systems. This will not only help the organization, but the industry as a whole. Effective communication is extremely important for business and IT systems now-a-days. With the help of this particular thesis, the importance of effective communication would have been reflected accordingly. The purpose of this research is therefore to analyze the communication problem between the designer and user during co-design mainly in the field of business and information technology and to create an understanding for how it is possible to create a better communication between the different parties in system development through co-design. Research can also be classified on the basis of the structure of the problem to be solved into exploratory, descriptive and casual research. The research can be regarded as exploratory research because large amounts of data can be gathered from the past researches and literature. Exploratory research explores the parameters of the problems in order to identify what should be measured and how best to undertake a study. In this research the qualitative data is gathered through detailed interviews and literature review. This helps in better understanding through words. Data is generated through the method of triangulation. The results will be presented using detailed analysis of data gathered from interviews and the analysis of theoretical part. It is a very challenging task to meet the changing needs of the business world. Designing effective information technology for this purpose is also very challenging. The co-design of business and IT systems has a lot of benefits for the organizations. The information technology is basically used to support business and its functions. Therefore it is extremely important that the information technology is aligned with the business processes. It should be considered as a part of the business and should not be designed independently. Effective Communication is important for managers in the companies in order to perform the fundamental management functions, i.e., Planning, Leading, Organizing, and Controlling. Communication facilitates managers to execute their jobs as well as responsibilities. Communication provides a foundation for planning. All the vital information should be communicated to the managers who consecutively should communicate the plans in order to apply them. Organizing also needs efficient communication with others regarding their job task. Hence, we can say that “effective communication is a basic element of successful business”. In other words, communication works as blood of organization. Strong literature review as well as strong capabilities towards research methodology and analytical part will certainly enhances the productivity of this thesis and will furnish good understandings among the readers.

    Aspects on the intensity and the relief of pain in the prehospital phase of acute coronary syndrome: experiences from a randomized clinical trial2010In: Coronary Artery Disease, ISSN 0954-6928, E-ISSN 1473-5830, Vol. 21, no 2, p. 113-120Article in journal (Refereed)
    Abstract [en]

    The primary aim of this study was to evaluate the pain relief and tolerability of two pain-relieving strategies in the prehospital phase of presumed acute coronary syndrome (ACS), and the secondary aim was to assess the relationship between the intensity and relief of pain and heart rate, blood pressure, and ST deviation. Patients with chest pain judged as caused by ACS were randomized (open) to either metoprolol 5 mg intravenously (i.v.) three times at 2-min intervals (n = 84; metoprolol group) or morphine 5 mg i.v. followed by metoprolol 5 mg three times i.v (n = 80; morphine group). Pain was assessed on a 10-grade scale before randomization and 10, 20, and 30 min thereafter. The mean pain score decreased from 6.5 at randomization to 2.8 30 min later, with no significant difference between groups. The percentages with complete pain relief (pain score <=1) after 10, 20, and 30 min were 11, 16, and 21%, respectively, with no difference between groups. Hypotension was less frequent in the metoprolol group compared with the morphine group (0 vs. 6.3%; P=0.03), as was nausea/vomiting (7.2 vs. 24.0%; P=0.004). At randomization intensity of pain was associated with degree of ST elevation (P=0.009). The degree of pain relief over 30 min was associated with decrease in heart rate (P=0.03) and decrease in ST elevation (P=0.01). In conclusion, in the prehospital phase of presumed ACS, neither a pain-relieving strategy including an anti-ischemic agent alone nor an analgesic plus anti-ischemic strategy in combination resulted in complete pain relief. Fewer side effects were found with the former strategy. Other pain-relieving strategies need to be evaluated.

    Vad påverkar användarens förtroende inom e-handel: en undersökning med fokus på omdömessystem2013Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Att skapa förtroende har visat sig vara en utmaning för företag inom e-handel. Syftet med studien är att ta reda på hur omdömessystem kan komma att påverka en användares förtroende och lyfta fram en möjlig förtroendekomponent i utformningen av en pålitlig e-handelsplats. Ett kundbaserat omdömessystem är en interaktiv försäljningskomponent som erbjuder kunder att dela och ta del av andras omdömen, åsikter, tankar och tidigare erfarenheter kring en produkt. De huvudbegrepp som behandlas i studien är omdömessystem, e-handel, förtroende och användbarhet. Studien utformades utifrån en kvalitativ forskningsmetod i syfte att få en djupförståelse inom området. Den empiriska insamlingsmetoden genomfördes i form av intervjuer som baserades på användbarhetstester ur sex olika användarperspektiv. Uppgifterna utfördes på två webbplatser, nelly.com och madlady.se, en webbplats med omdömessystem och en webbplats utan omdömessystem. I analysen ställdes den empiriska insamlingen mot den teoretiska referensramen för att skapa ett mönster och underlätta slutsatsen av studiens huvudfråga. Slutsatserna baserades på att utifrån delfrågorna besvara huvudfrågan och hur användarens förtroende påverkas i användningen av ett omdömessystem. Studiens reslutat understryker att omdömessystem är en förtroendeingivande komponent och möjliggör att användare på ett mer säkert och tryggt sätt kan handla över nätet. Omdömessystems effekter möjliggör att det kan ses som en avgörande faktor i val av produkt inom e-handel.

    Fractionation of the main components of barley spent grains from a microbrewery2009Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Barley spent grain, the main residue of the brewing industry, is a lignocellulosic material, which could be considered a potential raw material for ethanol production. In this work, spent grains generated in a microbrewery were fractionated by acid hydrolysis and delignification. The investigated sort of barley spent grains had high carbohydrate content, accounting for 60% of the dry matter, while its lignin content was lower than that reported for other sorts of spent grains. Since the used spent grains contained residual starch different treatment approaches were used for separating their main components without affecting the sugars generated by starch hydrolysis. Two kinds of acid hydrolysis processes, namely single-step and two-step hydrolysis, were used for solubilising the carbohydrate fraction. Single-step hydrolysis was performed either at 100oC or at 121oC. In the two-step approach, a second hydrolysis, at 121oC, was performed after the first hydrolysis step. The dilute-acid hydrolysis at 100oC removed all the starch, whereas the hydrolysis at 121oC removed also a part of the hemicelluloses in addition to starch. During the second hydrolysis step, the content of easily hydrolysable polysaccharides decreased from 32.5 to 7.6% in the material pre-hydrolyzed at 100oC and from 20.3 to 10.6% in the material pre-hydrolyzed at 121oC. The amount of easily hydrolysable polysaccharides removed in the second step corresponded to 83% and 81.5% of the total removed matter in the materials pre-hydrolyzed at 100 and 121oC, respectively. In the next step, acetosolv and alkaline delignification, either alone or combined with acid hydrolysis, were used for dissolving the lignin fraction. A higher solubilisation occurred after alkaline delignification, where 83% of the initial material was removed. Only 34% of the initial lignin was removed by direct acetosolv, while the combined acid hydrolysis/acetosolv approach resulted in lignin removal between 70 and 75%. However, the resulted pulp still contained important amount of lignin. The acid prehydrolysis was also beneficial for alkaline delignification, but the effect was less noticeable than for acetosolv. Lignin removal increased from 95% in direct alkaline delignification to nearly 100% in the acid hydrolysis-assisted alkaline treatment. Two different methods were carried out for lignin precipitation. In the liquid fraction obtained by acetosolv, lignin was precipitated by water addition after concentration of the liquors to 75% of the initial volume. Although the visual inspection of the liquors after water addition revealed a relatively good lignin precipitation, the separation by filtration of the precipitated material was difficult, apparently due to the small particle size of precipitated lignin molecules. Some improvement was observed for the combined treatments, especially for those including two-step acid hydrolysis. The best recovery, 54% of the precipitated lignin, occurred for the process including consecutive acid hydrolyses at 100 and then at 121oC before acetosolv. In the alkaline liquors, lignin was precipitated by pH adjustment to 2.0 by HCl. Around 40.5% of the solubilised lignin was precipitated, and it increased to 85-100% when combined treatments were applied. The best results were achieved upon the treatment including acid prehydrolysis at 121oC before alkaline process.

    Form, funktion & frihet: utveckling av längdskidåkningsjackor med fokus på mönsterkonstruktion2012Independent thesis Basic level (university diploma)Student thesis
    Abstract [sv]

    Bakgrunden till denna rapport är att det sportvarumärke jag samarbetat med ville utveckla en modell av längdskidåkningsjacka som fanns i deras sortiment. Undersökningen gällde att identifiera förbättringspunkter på en dam- och herrvariant av denna jacka. Avsikten var att bevara plaggens design och genom förändringar i mönstrens konstruktion förbättra passform och rörelsefrihet, och därigenom plaggets funktion. Genom att konstruera, sy toiler och prova av dessa på provmodeller, har rörelsefrihet och passform kunnat utvärderas. Resultatet visade att viktiga punkter var raglanärmens konstruktion, böjningen av ärmen, kragens form, ärmhålsdjup och placering av skärlinjer. Det blev också tydligt att kombinationen av designerns och konstruktörens kunskaper tidigt i processen är a och o för ett lyckat resultat. En tydlig kommunikation mellan dessa parter kan minska antalet provplagg under produktutvecklingen. Ämnen som också behandlats under arbetet är gradering, produktspecificering och deras betydelse för plagg och produktion. I undersökningen har jag även tittat på möjligheter till ytterligare utveckling av jackornas funktion om designen kan förändras, till exempel genom att flytta skärningar och på så vis ändra modellens utseende. This study was made due to a sports brand wanting me to develop a style of cross country ski jacket that are currently part of their collection. The study contained identifying areas of possible improvement in both a men and women´s jacket. The mission was to keep the design of the jacket and on the same time improve the fit and ease of movement in the garment (and thereby the function). Through analysis of style samples, pattern construction, sewing of proto samples and fittings on models, the fit and ease of movement has been evaluated. The results are that important garment elements are the neck width, scye depth, construction of the raglan sleeve, the pre-bent sleeve and the placement of cut lines. A conclusion is that to reach a functional and nice looking garment, the designer and the pattern constructor need to cooperate in the product development phase. Good communication between these two departments can reduce the number of proto samples that has to be made. Pattern grading, product specifications and their impact on the style and production process are subjects that are also presented and discussed in this report. During the project I have also studied the possibilities of further development through style design changes.

    Textile sound design2008Licentiate thesis, monograph (Other academic)
    Abstract [en]

    This thesis aims at developing conceptual and methodological tools in order to adapt sound within the textile design area. Occupational groups working with sound are to a large extent problem driven. Accordingly, textile designers working with sound- affecting properties of textiles concentrate on their dampening qualities. The ambition with this research project is to make suggestions how textile designers can work practically with textile sound design, in a more nuanced way. The overall aim of the thesis is to develop a vocabulary to make textile designers able to express the sound affecting qualities of textiles in a language full of nuances. As a starting-point the thesis briefl y describes commonly used methods and processes used to describe the expressiveness of a design, followed by a more thoroughly analyze of the textile design process illustrated by a practical example. These studies constitute a foundation to make it possible to see in what way these methods and processes will be affected when sound is added as new design tool. By studies of two sound design models, the fi rst attempts to develop a vocabulary concerning how to describe sound affecting qualities of a textile are developed. Research focusing on language issues, especially on the development of conceptual tools done at the research institute CRESSON, provides descriptive sound concepts, “sound effects”, embracing the interaction between human and his sound environment. These concepts are followed by a model of how to describe just a sound or “sound object” in “itself” (not in relation to anything else), developed by Pierre Schaeffer. These theoretical models have been complemented with empirical studies in form of a survey, named LISTEN. Interviews were performed from a phenomenological perspective. A number of informants were asked to tell about the sound environment and single sounds occurring at their working places. The interviews were interpreted from a phenomenographic perspective. A number of design projects are fi nally presented as practical examples of different ways to work with textiles and sound. The theoretical models provided by Schaeffer have been used to make the fi rst systematic attempts to describe sound environments; sounds and textiles sound affecting properties. Since the model presented by Schaeffer is developed to be used within musical composition the concepts have to be additionally modifi ed to be a useful tool within the textile design area. The thesis presents just the fi rst attempts to use this model. The next step to take in the research project is to adjust the theoretical systems of CRESSON and Schaeffer to suit the special area of textile design. The interactive ideas of a sound-affecting textile will also be a subject of further development.

    Att utvärdera i praktiken: en retrospektiv fallstudie av tre program för lokal folkbiblioteksutveckling2004Doctoral thesis, monograph (Other academic)
    Abstract [en]

    The study is placed within the area of library and information science (LIS) known as evaluation research and in particular, the area that relates to theory of evaluation practice. An analysis of previous research reveals that there is a need for conceptualising evaluation activities in the real life of libraries and information services and to reflect further on the conditions for evaluation in various institutional contexts. The aim of this study is to identify evaluation practice in public libraries, delimited to programs for local change and development, and to create an understanding for how this practice reflects institutional conditions within this particular context. The theoretical frame combine concepts from theories of program evaluation, theories of evaluation in library and information service and institutional theory. Evaluation is here considered as an ex post, systematic study with the purpose of describing and judging the merit of the implementation and results of a given activity and intervention. In this study an interpretative approach, based on the principles of hermeneutics and phenomen-ology, is used. The empirical study follows guidelines for qualitative case study and is designed in a retrospective and comparative manner. The study includes three different programs directed towards local change in public libraries, during the period 1986-1999. The sample includes thirty-nine (39) single studies each aimed at evaluating the programs. Data were collected from interviews and program documentation and were analysed on three levels. The first level concentrated on mapping the complex network of evaluation activities and identifying participants and their role in different evaluation processes. The second level was directed towards a clarificat-ion of the activities and subjective meaning of different tasks of evaluation in the context of each single program. On the third level of analysis certain aspects of evaluation practice were compared between the cases, which led to an aggregated description of both the pattern related to single tasks as well as to a more holistic description of the basic approaches through which evaluation practice in these kinds of programs can be understood. One conclusion is that evaluation practice, even in this limited context, is experienced as a com-plex phenomenon filled with contradictions and paradoxes. The main result of this thesis is the identification of a certain pattern, here conceptualised as three strategies. Strategies are labelled participatory evaluation , rational-managerial evaluation and pragmatic-political evaluation . Some remarks are made about in what way this pattern correspond to traditional theories of practice in LIS. One conclusion is that the practice of evaluation has almost nothing in common with scientific-expert approaches, mainly, it is argued, because the basic conditions for such a model do not seem to exist. Another conclusion is that institutional rules and norms are reflected in evaluation practice in varied ways and that evaluation both produces and reproduces the legitimacy of institutional identity. Evaluation cannot and should not be seen as a neutral or technical tool. It is suggested that further research should focus more on problems related to pragmatic-political aspects of evaluation practice as well as going further in the analysis of the deeper interaction between evaluation practice and institutional change.

    Utvärdering av offentlig verksamhet: begrepp kontext, motiv, strategier, användningen och aktörerna1997Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Based on a review of literature on evalution of public activities and in purpose to introduce a more general framework, this study describes a picture of the concept, context, motives, strategies, use and actors in Evaluation as these are experienced outside the field of library and information. The background is the increased need for" evaluations in public libaries and a need for new LIS knowledge about it. The reviewed literature has its origin in different disciplinary contexts and the study include contributions from policy studies, sociologi, education research, business administration, philosophy and anthropology. The focus, though, is not placed upon differences in the literature but on similarities. The review is organised in six parts. In the first part a presentation is given of how evaluations are conceptualized and its meaning in a historical perspective. In the second the focus is upon the context of public descision making, implementation and public programming. Different · purpuses of evaluation is discussed in the third part followed by a description of strategies and models in the fourth. Issues of evaluation use is discussed in part five and finally is a presentation of those actors of particular-importance in evaluations given in part six. In the reviewed literature the -author finds some general patterns, who are assembled and described in a comprehensive discussion. In the contusion some claimes are made about the nature of evaluation. One claim is that evaluations are of great complexity and given several functions. This complexity is explained by the fact that evaluative activities are of increased concern and importence for numeorous actors and their relevance for many fields of practice. Future research is suggested to focus on the role of evaluation in the perspective of politicaland adminstrative governance, program change and development, scientific knowledge and in the perspective of negotiations and communication in social and political conflicts.

    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.

    Strukturerad kreativitet2007Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [sv]

    Ordet kreativitet används flitigt idag av ledare, kreativitetskonsulter, konstnärer, unga som gamla. Vissa ser kreativiteten som en ekonomisk drivkraft, andra tycker att den gör vårt liv mer spännande. På sistone har det vuxit fram många kreativitetsprofessioner, så kallade kreativitetsexperter som säger sig veta vad kreativiteten är och har en universal lösning för stimulering av den och vet hur man leder den. Jag kallar det att strukturera kreativiteten genom klichéspråk. Genom att kommunicera kreativiteten med det klichéspråket gör vi illa själva kreativiteten. Vi beundrar kreativiteten och vi plundrar kreativiteten. Vi förtar möjligheten med ordet, den rena kreativiteten, spontana kreativiteten som finns i alla människor, som bara existerar. Syftet med uppsatsen är att åstadkomma en reflektion runt frågan vad händer med kreativiteten när man utnyttjar den och jag förväntar mig att inte ställas till svar om vad kreativiteten är, för jag har ingen facit. Den här essän är en berättelse där jag, genom det hermeneutiska synsättet, tolkar teori och intervjuer med kreativa människor som jag har i studien ur ett ironiskt perspektiv. Det ironiska perspektivet hjälper mig att handskas med motsägande situationer, och skyddar mig själv mot mina egna emotionella reaktioner som den strukturerade kreativiteten förorsakar. Att vi själva är en del av den strukturerade kreativiteten utan att vi är medvetna om det är svårt att förklara på något annat sätt än ironiskt.

    How robustness and resilience support security business2011In: Journal of Transportation Security, ISSN 1938-7741, E-ISSN 1938-775X, Vol. 4, no 3, p. 201-219Article in journal (Refereed)
    Abstract [en]

    Supply chain disruptions may derive from various sources but the antagonistic threats are centered in supply chain disruption. Antagonistic threats are dynamic due to the spiral input, processes and feedbacks which create a very complex situation to analyze, assess and making decision. Beside risks, vulnerability derived from supply chain characteristics is the other issue which should be measured. Antagonistic threats are magnified in such vulnerable supply chains. After 9/11, 2001, the Security and Efficiency of the global supply chain has become an important issue in global transportation. This leads firms to consider Supply chain security as part and parcel of a company’s comprehensive risk-management program. In a security business, it is essential to understand different type risks and evaluate transportation assets, do risk based prioritization, and protect customers through cost effective actions. This could be occurred corresponding to risk management methods. Providing security may occur internally by firms or they outsource it to security providers which could be performed in higher quality or more cost effectively. In this article, we focus on managing the risks and securing the supply chain business with the security theory and strategies in the supply chain and transportation network. In order to discover risks throughout the supply chain, security provider needs to find risk hot spots where the likelihood of risk is higher. We propose two approaches (geographical and elements/process) to seek probable risks. The next step is to take strategies for risk prevention and risk mitigation. Consequently, we connect the security strategies from the literature review and collected information from security business to suggest a suitable model of how to handle the risks and achieve security in a systemic and scientific way.

    Konsumentbeteende för barnmat i Kina: faktorer att överväga inför expansion2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this research was to examine the consumer behavior for baby food in China,which in turn led to identifying factors, which Swedish baby food companies should considerwhen thinking about an expansion to China. Due to the lack of security for baby food inChina, there has been an increase of the demand for foreign baby food in China. This has ledto potential for many companies. Factors have therefore been identified which can affect theapproach for an expansion for a Swedish baby food company in China.The research was conducted through a mixed method methodology where a self-administeredquestionnaire was executed in China towards Chinese consumers and a semi-structuredinterview was executed with the Swedish baby food company Child Food Factory. Thequestionnaire examined the consumer behavior for baby food in China in order to identify theattitudes and values that exist. Furthermore, consumers' buying habits and needs for babyfood was examined, as well as opinions regarding foreign baby food and organically producedbaby food. The semi-structured interview examined the concept which Child Food Factoryhas for their product and how the product will be received by the Chinese market, this sinceChild Food Factory was in the process of bring their baby food product in to China.The empirical findings were analyzed and the results comprises of identified characteristics inthe Chinese consumers concerning consumer behavior and values for baby food. Some of thecharacteristics that were identified was that the Chinese consumers are affected mostly byfamily, friends and relatives when it comes to purchasing baby food and the most commonway to purchase baby food is in a supermarket. They also felt that safety was the mostimportant attribute for baby food.Furthermore, the factors regarding baby food in the Chinese market were identified forSwedish baby food companies to consider if planning an expansion to China. Some of thefactors that were identified was that baby food companies need to consider their marketing sothat it is adapted to the Chinese culture. The baby food companies also need to bear in mindthe fact that family and security have a big influence. Another factor is to be able to use theadvantage of being a foreign company in a strengthening way for the expansion to China.Please note that this research is written in Swedish.

    Not Bad: Passive Leg Raising in Cardiopulmonary Resuscitation-A New Modeling Study2017In: Frontiers in Physiology, ISSN 1664-042X, E-ISSN 1664-042X, Vol. 7, p. 665-Article in journal (Refereed)
    Abstract [en]

    Aim: To evaluate, using a simulated haemodynamic circulation model, whether passive leg raising (PLR) is able to improve the effect during cardiopulmonary resuscitation (CPR); to expose the possible reasons why PLR works or not.

    Materials and Methods: We adapted a circulatory model for CPR with PLR. First we compared cardiac output (CO), coronary perfusion pressure (CPP), blood flow to heart (Qheart), and blood flow to neck and brain (Qhead) of standard chest compression-only CPR with and without PLR; second we simulated the effects of PLR in different situations, by varying the thoracic pump factor (TPF) from 0 to 1; third we simulated the effects when the legs are lifted to the different heights. Finally, we compared our results with those obtained from a published clinical study.

    Results: According to the simulation model, (1) When TPF is in the interval (0,1), CPP, CO, Qheart, and Qhead are improved with PLR, among them with half-thoracic/half-cardiac pump effect (TPF is 0.5), CPP, CO, Qhead, and Qheart increase the most (by 14, 14, 15, and 17%). (2) When TPF is 1 (pure thoracic pump, with an emphysema or extremely thick thorax), PLR has almost no effect on CPP, CO, and Qheart (-1, 2, and 0%), whereas Qhead is increased by 9%; (3) Regardless of whether there is a cardiac or thoracic pump effect, PLR is able to increase Qhead by 9-15%. (4) When the legs are lifted to 30 degrees to the ground, the volume transferred from legs to upper body is 36% of the initial volume in legs; when the legs are lifted to 45 degrees , the volume transferred is 43%; when the legs are lifted to 60 degrees , the volume transferred is 47%; when the legs are lifted to 90 degrees , the volume transferred is 50%.

    Conclusion: Generally PLR is able to achieve improved cerebral perfusion and coronary perfusion. In some extreme situations, it has no effect on cardiac output and coronary perfusion, but still improves cerebral perfusion. PLR could be a beneficial supplement to CPR, and it is not necessary to lift the legs too high above the ground.

    Our way(s) to Action Research: Doctoral students' international and interdisciplinary collective memory work2014In: Action Research, ISSN 0264-5122, Vol. 12, no 3, p. 293-314Article in journal (Refereed)
    Abstract [en]

    This study involved six Swedish and Canadian doctoral students who shared interests in using action research in professional education in different disciplines. We employed Noffke’s three dimensions of action research as a theoretical framework (i.e., the Professional, the Personal, and the Political). Using collective biography as a methodology, we cooperatively examined how our personal and professional agendas and macro-level structures have been shaping our intentions to conduct action research projects in our respective disciplines. The key findings of this international and interdisciplinary collective biography relate our growing awareness of the intimacy between research and life in vari- ous professional and geographic contexts. Collectively addressing our shared frustrations, we celebrated action research as a methodology that attends to the dynamic and concrete lived experiences of our participants in various spatio-temporalities. Reflecting upon the hybridity of our own researcher identities, we were also able to see the intimate relation between ourselves as active citizens and critical action researchers who are determined to take up the challenges and engage in critically oriented action research that could nurture more ‘‘caring,’’ ‘‘empowering,’’ and ‘‘transforming’’ public spheres.

    Decision Support System- Research on the application of DSS in China's Banks2011Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Information system is widely used in financial area all around the world today, and business intelligence systems has draw more and more attention from both academia and business circles. Based on this situation, we carried out our research. The main purpose of our research is to find out how Decision Support System (DSS) is used in China's banks. As there are more than five hundred banks in China, we choose the four biggest commercial banks(which has cover more than 85% of financial activities in China's banking area) as examples to study. We sent Emails and made telephone calls to different roles in these four banks, from chief information officer, managers of business to normal staff. Before carried out interviews, we did literature study to set a scientific background for our interviews. After the collection and analysis of data from both interview and literature study, the result is presented in three chapters. The theoretical study part introduces the theory background of DSS and how it is used in banks, the framework of the DSS and the basic model of the DSS, also new techniques in DSS. The Empirical results part introduces the results got from interviews. In Analysis part the results from the former chapters will be combined and analyzed, in this part we presents the application situation of DSS in China's banks, the affection of DSS on banks employees and improvement and drawback DSS brings to China's banks. Also new technology of decision support system and its application. And the last part we would draw conclusions for this thesis and summarize results from the interviews and theories and evaluate the whole research process. And the introduction of our research and the methods used to achieve the research goal will be introduced in the first two chapters.

    The intention to use mobile network service: with gender as moderating factor2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of the study was to find out and analysis the factors that can influence people's choice to mobile network service. Based on our research, we can give some practical advice to consumer and telecom companies.To achieve the purpose of the study we design a questionnaire and send it to our friends in Shanghai and Jinan China. The questionnaire was built around some questions about which factors can influence people’s choice and the importance of each factor.The study was performed with a quantitative research approach. We found five factors that affect users to choose different mobile networks, respectively usefulness, ease of use, price, speed and enjoyment. And in this paper we also proposed five hypotheses to test the relationship between these factors and gender. This provides us the theoretical basis to our research. The factors were included in our questionnaire, so the questionnaire gives the research some basic data. We analyze the data through the processional software SPSS.We have analyzed every aspect of our questionnaire. We put the data together and make visual figures. The figures make people easily understand the questions. Also these data help us understand the phenomena clearly and make a contribution to our study.Based on the findings, the research could be validated with a data analysis which gave grounds for the conclusion part.

    Teknisk utvärdering av en ny miljövänlig förbehandlingsmetod av biomassaavfall med utspädd salpetersyra2012Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Bio-refining of renewable resources such as waste biomass into value added products has increased rapidly over the last decades. The aim is to find new environmentally friendly yet economically feasible ways of replacing current utilization of non renewable resources. It can be expected that a commercially viable next generation bio-ethanol will be produced from lignocellulosic feedstock in the near future. This master thesis set out to look at a specific Canadian company in depth (Pure Lignin Environmental Technology Ltd), known as PLET henceforth. PLET has a new approach in pre-treatment of biomass, with a recently patented environmentally friendly technology, which could be extremely lucrative if applied in the right context. It is desirable to look at the possibility of using the master thesis as a take-off platform to launch a consulting bio-tech company directly after completion. There are several different ways to process biomass into higher value added products. In this master thesis focus is laid upon biomass waste, but the same principles could be applied on biomass processing in general. That is the separation and purification of products. In order to put the technology of PLET into a context, other company approaches are used as a comparison, such as SEKAB E-Technology, Lignoboost and Borregaard Lignotech. It is however hard to find suitable examples equivalent to the PLET approach since the technology of PLET considers all the three constituents of wood as raw material for production of three stand alone commercial products; pure lignin, pure cellulose and hemi-cellulose. These three products are separated and purified in the pre-treatment process at high yield and practically no formation of by-products. Process parameters are only moderately adjusted depending on what raw material is used. The catalytic reactor process (=CRP), is performed by PLET as a pre-treatment in a continuous and batch system, in which lignocellulosic material (= wood chips, saw dust or other waste biomass) undergo acid catalyzed hydrolysis by dilute nitric acid. The impregnated wood chips are partially depolymerised from the lignin matrix when heated in the low pressure catalytic reactor. After that, follows distillation, condensation and almost complete recovery of dilute nitric acid. After CRP, the cellulose pulp is separated from the black liquor by an alkaline solution (=NaOH). The obtained black liquor is pumped to a separation tank to precipitate lignin and sweet liquor through filtration. The final step is to dry the lignin, while the sweet liquor is utilized by Torula yeast (=Candida utilis) in order to produce unicellular protein. It would be interesting to see if the pre-treatment that PLET provides, could be exploited in a context of production of next generation of cellulosic ethanol from the cellulosic part of waste biomass. In this master thesis, an evaluation of producing next generation ethanol from dilute-nitric acid pre-treated cellulose rich softwood was performed and dilute sulphuric acid pre-treated hemi-cellulose rich hardwood birch pulp was used as a comparison. The technical part of this master thesis was conducted on a laboratory scale, using samples from two companies, referred to as PLET and SEKAB E-technology (Sweden). The strategy of PLET is currently to find a commercial platform to produce value added products from waste biomass generated by saw mills and pulping industries, while SEKAB E-Technology mainly works with Swedish softwood as a raw material. iv Experiments of this master thesis includes a series of fermentation trials using either SSF (= Simultaneous Saccharification and Fermentation) or SHF (= Separate Hydrolysis and Fermentation). Yields of the enzymatic hydrolysis and subsequent fermentations were estimated with HPLC measurements complemented with dry weight measurements. Obtained experimental data support the potential to make lignocellulosic ethanol out of either softwood or hardwood. Ethanol yield from dry material from SEKAB E-Technology hardwood birch slurry was 0.43 (g ethanol / g dry raw material), whereas samples supplied by PLET achieved the following results. The ethanol yield from dry material from softwood pine washed cellulose was 0.33 g (ethanol / g cellulose). The ethanol yield from dry material obtained for softwood pine unwashed cellulose in the three SHF was 0.47; 0.34 and 0.19 (g ethanol / g cellulose) respectively, while the yield in the two SSF was 0.45 and 0.46 (g ethanol / g glucose). The economical part of this master thesis includes the use of Business Model Canvas and the NABC- model (= Need, Approach, Benefit and Competition) to define the basic topics and tasks that need to be addressed in the start up phase of a small consulting bio-tech company. At least 6 million US dollars is needed as a minimum starting capital to be able to construct a small commercially viable pilot plant, according to PLET. This investment would cover the basic requirements and is scalable. The construction could preferably be done in Sweden in the vicinity of an existing saw mill or paper pulp industry or elsewhere, where a steady supply of cheap raw material could be assured. The size of the operation envisioned, depends greatly on location and adjacent businesses. Large pulp mills in the range of 400-500 MWh would be preferred, the largest pulp mills in Canada process 5000 ton per day which is equivalent to a capacity of 1 GW wood per day (GW = giga watt), but the concept of the technology of PLET must first prove its value on a smaller scale. According to PLET, a future full scale production plant could be designed for processing 56 tons of wood chips per day of wood chips would generate annual revenues of ≈ 7500000 US dollars. The annual profit would be ≈ 2500000 US dollars, and capital cost (equipments) ≈ 5000000 US dollars, while the payback time on investment would be 2-3 years. According to PLET, the products are estimated to have the following values; 25 tons/day of pure cellulose with a market value of 400-500 US dollars/ton, 10 tons/day of pure lignin with a market value of 1000-1200 US dollars/ton and finally 21 tons/day of sweet liquor with a market value of 50-100 US dollars/ton.

    Abstract [en]

    By the rapid development of electronic commerce, many problems are emerging in logistics systems within developing countries. For developing countries such as China, India, and other southeastern countries Logistics is becoming a major part of GDP and logistics cost constitute a large portion of supply chain costs especially for businesses with international relations which is being more and more widespread in parallel with development of IT and e-commerce. Such an interactive juxtaposition of logistics and e-commerce motivated us to look at how small and medium sized enterprises (SMEs) are run, and of course through a lens that sees these two concepts together. Another point that spiced our motivation was the bloom of virtual businesses especially those with one head in developing countries and the other in developed countries. According to The CIA 2006 fact book, there are 137 million internet users in China. As e-commerce and its logistics support systems in China have a huge effect in the global trade, we have targeted our thesis case towards China. We have narrowed down our case to Chinese SMEs, which are small and medium sized Enterprises located in china; as SMEs, which their number has reached to 42 million, are now responsible for more than 90% of China's industrial output [1]. How the Chinese Electronic business should manage the way logistics must be integrated with e-commerce is the study which the thesis concerned about. In this research we are going to argue the barriers to ecommerce adoption in China, logistics-based barriers to successful SME establishments in china and also put up some suggestions upon possible strategies that can facilitate this process. We have concluded the thesis with two models, one for e-commerce adoption inside SMEs and the other one for Business to Business (B2B) and Business to Customer (B2C) e-commerce development. We didn‟t make any effort for developing a strategy for logistics leg of e-logistics due to the limited size of research and time barriers. The property that differentiates this study from previous similar studies is that here we face business environment in a different way and consider culture and government as two most important features of Chinese business environment.

    DFT and tight binding Monte Carlo calculations related to single-walled carbon nanotube nucleation and growth2010In: Carbon, ISSN 0008-6223, E-ISSN 1873-3891, Vol. 48, no 2, p. 470-478Article in journal (Refereed)
    Abstract [en]

    Density-functional theory (DFT) calculations for idealized nucleation processes of (5,5) and (10,0) single-walled carbon nanotubes (SWCNTs) on a 55 atom nickel cluster (Ni-55) showed that it requires a larger chemical potential to grow a carbon island (which is the simplest structure that can lead to formation of the SWCNTs) on the cluster than to extend the island into a SWCNT or to have the carbon atoms dispersed on the cluster surface. Hence, in the thermodynamic limit the island will only form once the (surface of the) cluster is saturated with carbon, and the island will spontaneously form a SWCNT at the chemical potentials required to create the island. The DFT (zero Kelvin) and tight binding Monte Carlo (1000 K) also show that there is a minimum cluster size required to support SWCNT growth, and that this cluster size can be used to control the diameter, but probably not the chirality, of the SWCNT at temperatures relevant to carbon nanotube growth. It also imposes a minimum size of clusters that are used for SWCNT regrowth. (C) 2009 Elsevier Ltd. All rights reserved.

    Diameter and Chirality Changes of Single-Walled Carbon nanotubes During Growth: An ab-inition Study2009In: Journal of Nanoscience and Nanotechnology, ISSN 1533-4880, E-ISSN 1533-4899, Vol. 9, no 2, p. 1222-1225Article in journal (Refereed)
    Abstract [en]

    We use density functional theory to investigate possible changes of the diameter and chirality of single-walled carbon nanotubes (SWNTs) during catalyzed growth on a nickel cluster. The interplay of nanotube curvature, defects, and carbon-metal interaction dictates if a change is energetically favorable. We found that, given a sufficiently large Ni cluster, both zigzag and armchair nanotubes tend to increase their diameters during growth. This increase leads to a larger increase in energetic stability for smaller diameter nanotubes. Chirality changes are also demonstrated. Our findings impact on the possibility of using the recently proposed nanotube-seeded continued growth of SWNTs to control their chirality.

    Influencer Marketing: the characteristics and components of fashion influencer marketing2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The ad blocking hype has brought new challenges for fashion brands to be seen and heard. Therefore new marketing strategies have to be found. Since the usage of mobile devises increased and consumers spend more time on online social networks - influencer marketing had been found as a authentic marketing channel to reach the consumers. Therefore this thesis aims on providing fashion brands a guideline of the components and characteristics of influencer marketing. To accomplish this research objective the qualitative method approach of expert interviews had been chosen and four experts from the fashion influencer marketing were questioned about their daily work with influencers to elaborate their needs and the challenges they are facing. The interviews lead to four core components of influencer marketing: authenticity, long-term relations, co-creation and micro-influencers. Underneath these core components the following sub-components were found: brand fit, exclusivity, visual language, passion, trust, price, creative freedom, and frequent communication. The main conclusion of this study is that working with micro influencers is key a component of influencer marketing. These influencers tend to have high authenticity, are experts in a certain niche and are not motivated by monetary reasons.

    Different defibrillation strategies in survivors after out-of-hospital cardiac arrest.2018In: Heart, ISSN 1355-6037, E-ISSN 1468-201X, Vol. 104, no 23, p. 1929-1936Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: In the last decade, there has been a rapid increase in the dissemination of automated external defibrillators (AEDs) for prehospital defibrillation of out-of-hospital cardiac arrest patients. The aim of this study was to study the association between different defibrillation strategies on survival rates over time in Copenhagen, Stockholm, Western Sweden and Amsterdam, and the hypothesis was that non-EMS defibrillation increased over time and was associated with increased survival.

    METHODS: We performed a retrospective analysis of four prospectively collected cohorts of out-of-hospital cardiac arrest patients between 2008 and 2013. Emergency medical service (EMS)-witnessed arrests were excluded.

    RESULTS: A total of 22 453 out-of-hospital cardiac arrest patients with known survival status were identified, of whom 2957 (13%) survived at least 30 days postresuscitation. Of all survivors with a known defibrillation status, 2289 (81%) were defibrillated, 1349 (59%) were defibrillated by EMS, 454 (20%) were defibrillated by a first responder AED and 429 (19%) were defibrillated by an onsite AED and 57 (2%) were unknown. The percentage of survivors defibrillated by first responder AEDs (from 13% in 2008 to 26% in 2013, p<0.001 for trend) and onsite AEDs (from 14% in 2008 to 30% in 2013, p<0.001 for trend) increased. The increased use of these non-EMS AEDs was associated with the increase in survival rate of patients with a shockable initial rhythm.

    CONCLUSION: Survivors of out-of-hospital cardiac arrest are increasingly defibrillated by non-EMS AEDs. This increase is primarily due to a large increase in the use of onsite AEDs as well as an increase in first-responder defibrillation over time. Non-EMS defibrillation accounted for at least part of the increase in survival rate of patients with a shockable initial rhythm.

    Alternativ utvecklar förmågan till kritisk reflektion2011In: Lärarutbildning och vetenskaplighet, ISSN 1404-0913, no 2, p. 83-98Article in journal (Other academic)
    Abstract [sv]

    I mitt yrke som lärare vid en lärarutbildning får man ibland frågan av nyantag-na studenter om varför man ska lära sig olika teorier. Vad ska man med teori till? Studenten som frågar ser ofta teori som väsenskilt från praktik och vill en-bart ha praktiska svar. Studenten vill att jag ska tala om hur man ska handla i en viss situation. Det handlar oftast om en problematisk situation som kan upp-stå mellan lärare och elev i studentens kommande yrkesliv. Studenten vill inte ha en massa teori om varför denna situation har uppstått eller någon teori om varför hon eller han kan handla på ett visst sätt, utan studenten vill enbart ha svar på hur hon eller han ska handla i denna situation. Det kan handla om hur studenten ska agera i en situation där en elev vägrar att ta av sig sin keps i bör-jan av lektionen. Jag anser att det inte går att svara på frågor av detta slag med ett enkelt svar som beskriver exakt hur studenten ska handla. I denna text kommer jag att svara på frågan om varför man inte kan ge ett ”teorilöst” prak-tiskt svar på frågan om hur man ska agera i en situation där exempelvis eleven inte vill ta av sig kepsen (exemplet förutsätter att skolan där eleven går har ordningsregeln att elever inte får bära keps inomhus. Om detta är en bra eller dålig regel är dock en annan diskussion). Jag kommer i texten nedan argumen-tera för varför man behöver teori. Framförallt kommer jag att föra en argumen-tation om varför man som lärarstudent behöver lära sig flera olika teoretiska synsätt. Det vill säga varför det är utvecklande att lära sig flera alternativ.

    Det tillåtande och det begränsande: En studie om pojkars syn på studier och ungdomars normer kring maskulinitet2018Doctoral thesis, monograph (Other academic)
    Abstract [en]

    Girls preform generally better than boys in school. In many schools the dominant norms of masculinity are a hinder for boys to preform in school. Schools with a dominating “anti school culture” or a “effortless achievement culture” among the boys are examples of this. These norms of masculinity are also a hinder for girls to show their ability in different subjects. The overall aim of the thesis is to study boy’s view on studying and it´s relation to norms of masculinity. It also focuses on the question if the ability to study is gendered. The collecting of data was done through an ethnographic inspired study where 15 group interviews and different kind of observations was used. Two classes, class 9d and 9e, in year nine in a secondary school was followed during a three-month period. Class 9d consisted of 20 pupils (13 girls and 7 boys) and 9e consisted of 19 pupils (9 girls and 10 boys). Around half of the pupils came from a working class home and the other half had parents with collar professions. Around one forth of the pupils had a history of immigration in the family In conclusion a “study culture” was dominating among the boys. The norm among both the girls and the boys was that you should study. Boys could openly study ambitious without any social cost. With a social cost I mean being teased, ridiculed or losing status in the social context. This norm was beneficial for both girls and boys at the school. The result shows that challenging a “anti school culture” or a “effortless achievement culture” is of great importance for both sexes. Despite their being at dominant “study culture” among the boys, girls on average still preform better than boys. This was because the ability to study was gendered. So even if boys were “allowed” to study as ambitious as girls without any social cost, they haven’t developed the same ability to do so because of different social expectations on girls and boys. In other words, did parallel and contradicting norms exist at the school. Some norms were “allowing” boys to study ambitious, other norms was “limiting” and a hinder for boys to do this.

    Hur kan lärare motverka en antipluggkultur bland pojkar2019In: Paideia, ISSN 1904-9633, no 17, p. 15-24Article in journal (Refereed)
    Abstract [sv]

    Utifrån frågan varför pojkar generellt presterar sämre i skolan än flickor har det gjorts flera studier i skolor med en dominerande ”antipluggkultur” eller en dominerande ”ingen ansträngningskultur” bland pojkarna. Dessa studier visar att de normer som konstrueras bland pojkar försvårar deras möjligheter att studera. Denna artikel fokuserar på en studie utförd på en skola med en dominerande ”pluggkultur” bland pojkarna. I texten framläggs hur lärarna har bidragit till att konstruera en ”pluggkultur”. Utifrån pojkarnas egna utsagor har lärarna bidragit till att skapa dominerande normer bland pojkarna som de själva hävdar gynnar deras studier. Normer kan vara hindrande, men detta specifika fall visar att normer även kan upplevas som möjliggörande.

    Pojkar i skolan: Vad lärare och andra vuxna behöver veta för att fler pojkar ska lyckas i skolan2019Book (Other academic)
    Abstract [sv]

    Pojkar har under flera decennier presterat sämre i skolan än flickor, och betygsgapet ökar. Detta är ett av skolans tydligaste likvärdighetsproblem. I den här boken ges en översikt över olika fenomen som bidrar till att pojkar som grupp presterar sämre i skolan än flickor. Utifrån dessa diskuteras hur lärare och andra vuxna kan bidra till att bryta den negativa trenden och få fler pojkar att lyckas i skolan.

    Orsakerna kring pojkars sämre resultat är flera och sammanflätade. Det finns biologiska könsskillnader som missgynnar pojkar i skolan, skillnader som förstärks i det sociala samspelet av vuxna i barnens närhet. En breddad repertoar är en nyckelterm i boken som hänvisar till att pojkar behöver utveckla fler förmågor istället för att begränsas i sin utveckling av de könsnormer och maskulina ideal som påverkar många pojkars liv idag. Fredrik Zimmerman presenterar sin egen forskning på en skola som har en dominerande pluggkultur bland pojkarna. Författaren beskriver hur lärarna arbetar för att frambringa de framgångsfaktorer som enligt pojkarna själva skapar en lärande miljö och hjälper dem att ta ett allt större ansvar för sina studier. Samtidigt får detta arbete en positiv effekt på den allmänna trivseln, vilket visar sig i att även flickorna säger att de trivs bättre i denna skolmiljö.
