Fit in to stand out : An experience perspective on value creation

In order to grow and survive, a firm must create value with consumers in ways that both fit in with consumer demands and stand out from competitors. Focusing on and understanding consumer and firm assessments of value and creation of value has become a central scope in the contemporary strategic management and marketing literature for understanding and explaining firm survival and success. Consequently, the overall aim of this thesis is to provide a conceptually and empirically grounded understanding of consumers’ and managers’ value assessments and behavior in value creation. This thesis draws on a consumer experience perspective and theories on social construction, organizational identity, self-congruence, and the theory of attractive quality, and combines multiple qualitative and quantitative studies. The findings in this thesis shed light on the interplay between consumers, firms, and contextual structures in value creation. Contextual structural, cultural, and political forces are shown to affect and be affected by the shared and individual cognitions of value creation that firms and consumers use in their assessment and creation value. The results of the study enhance the understanding of how firms can adopt various strategic schemas or organizing logics to optimize different types of use value creation when choosing between opposing and contradictive demands in their value creation. Furthermore, the thesis provides a deeper understanding of the hierarchical nature of consumer judgments of value that can be used to enhance the effectiveness of firm prioritizations and as a foundation for future value-creating strategies.

Morphology and material stability in polymer solar cells

Polymer solar cells are promising in that they are inexpensive to produce, and due to their mechanical flexibility have the potential for use in applications not possible for more traditional types of solar cells. The performance of polymer solar cells depends strongly on the distribution of electron donor and acceptor material in the active layer. Understanding the connection between morphology and performance as well as how to control the morphology, is therefore of great importance. Furthermore, improving the lifetime of polymer solar cells has become at least as important as improving the efficiency.   In this thesis, the relation between morphology and solar cell performance is studied, and the material stability for blend films of the thiophene-quinoxaline copolymer TQ1 and the fullerene derivatives PCBM and PC70BM. Atomic force microscopy (AFM) and scanning transmission X-ray microscopy (STXM) are used to investigate the lateral morphology, secondary ion mass spectrometry (SIMS) to measure the vertical morphology and near-edge X-ray absorption fine structure (NEXAFS) spectroscopy to determine the surface composition. Lateral phase-separated domains are observed whose size is correlated to the solar cell performance, while the observed TQ1 surface enrichment does not affect the performance. Changes to the unoccupied molecular orbitals as a result of illumination in ambient air are observed by NEXAFS spectroscopy for PCBM, but not for TQ1. The NEXAFS spectrum of PCBM in a blend with TQ1 changes more than that of pristine PCBM. Solar cells in which the active layer has been illuminated in air prior to the deposition of the top electrode exhibit greatly reduced electrical performance. The valence band and absorption spectrum of TQ1 is affected by illumination in air, but the effects are not large enough to account for losses in solar cell performance, which are mainly attributed to PCBM degradation at the active layer surface.

As estratégias de internacionalização de empresas portuguesas: os casos de multinacionais e PMEs

O principal objetivo do presente estudo visa analisar as estratégias de internacionalização adotadas por empresas portuguesas de diferentes indústrias, e identificar alguns fatores que potenciem o sucesso das empresas durante este processo de internacionalização. Deste modo optou-se por um estudo qualitativo com entrevistas semiestruturadas baseadas num guião de entrevista (gravadas em áudio e transcritas na totalidade), envolvendo os diretores / responsáveis nas empresas por esta área da internacionalização, em seis empresas diferentes; foi ainda entrevistado um especialista em internacionalização com background desenvolvido no exercício de funções enquanto colaborador da AEP. Segundo foi apurado neste estudo destacam-se as áreas de relações humanas (rede de contactos (network); o know-how sobre o mercado local; as relações de confiança; proximidade cultural e linguística (CPLP)) e a capacidade técnica das empresas (a proximidade geográfica dos mercados; a adaptabilidade da empresa; a capacidade financeira e de inovação) como sendo fundamentais para a internacionalização de sucesso. Estes fatores supracitados potenciam o sucesso em novos mercados para as empresas complementando assim o que é apresentado pelas diferentes teorias na literatura (e. g. teoria de Uppsala). De notar que Blake e Mouton e estudos da Universidade de Michigan referem aspetos técnicos (da tarefa e da produção) e de relações humanas (preocupação com as pessoas) como sendo importantes na liderança de empresas, fatores que agora alargamos à internacionalização. Outro fator fundamental para o sucesso da internacionalização das empresas estudadas é a masculinidade, ou seja, a assertividade e a orientação para o sucesso dos gestores entrevistados e responsáveis pela área da internacionalização. De acordo com o modelo de Hofstede (2001), referido no capítulo 5, Portugal apresenta-se como sendo pouco masculina e pouco assertiva, coletivista, e com maior distância de poder. No entanto, a informação recolhida neste estudo, nomeadamente nas entrevistas, mostra aspetos contrários, ou seja, os diretores mostram-se mais masculinos, impulsionados também pela dificuldade acrescida de conquistar negócios em ambientes internacionais. Assim, os resultados e a competição revelam-se como sendo preocupações fundamentais, mas sem no entanto menosprezar os aspetos femininos de qualidade de relacionamento interpessoal.

Towards an Orthodox Marxian Reading of Subsumption(s) of Academic Labour

This paper deploys an orthodox Marxian reading of the concept of subsumption of labour under capital. It does so through a brief, critical overview of the components of the Marxian conceptual instrument of subsumption of labour under capital (formal, real, hybrid and ideal subsumption). Recapitulating Marx’s concept, it sheds some light on the consequences of such a reading as a way of understanding the current transformation of the global higher education sector into a capitalist production sector per se. The reconstruction is then considered here as an attempt to approximate the specifics of the subsumption of labour under capital within the higher education sector. Moreover, the paper aims at showing that a discussion of the university dominated by capital with reference to the functioning or constituting of markets does not provide real opportunities for the understanding and solution of such problems as precarization, exploitation or acceleration of academic work. Thus, it joins a wider stream of Marxist higher education research and could be seen as a conceptual contribution to a critique of the political economy of higher education.

Representera och bli representerad : Elever med religiös positionering talar om skolans religionskunskapsundervisning

Hur kan lärare på bästa sätt möta elever med religiös positionering i religionskunskapsklassrummet?  Hur kan undervisningen utformas för att ge religiösa traditioner en framställning som elever med religiös positionering kan acceptera, relatera till och kanske också lära nytt av? Den här religionsdidaktiska studien handlar om hur elever som positionerar sig inom muslimsk, kristen, buddhistisk och judisk tradition talar om skolans religionskunskapsundervisning. Studien berör tre teman. För det första undersöks mötet mellan undervisningsinnehåll och elevernas erfarenheter av sin egen religiösa tradition och tro. För det andra riktas uppmärksamheten mot hur eleverna talar om sina erfarenheter av att vara eller att förväntas vara representant för sin egen tradition i undervisningen. Ett tredje tema handlar om hur eleverna beskriver ramar och förutsättningar för religionskunskapsundervisningen. Intervjumaterialet har analyserats med hjälp av kritisk diskursanalys. Resultaten visar bland annat att eleverna har svårt att känna igen och relatera till sin egen tradition i undervisningen. De befarar att undervisningen snarare förstärker än dekonstruerar stereotypa föreställningar om religion och religiöst liv. 

On the Bleeding Edge : Debloating Internet Access Networks

As ever more devices are connected to the internet, and applications turn ever more interactive, it becomes more important that the network can be counted on to respond reliably and without unnecessary delay. However, this is far from always the case today, as there can be many potential sources of unnecessary delay. In this thesis we focus on one of them: Excess queueing delay in network routers along the path, also known as bufferbloat. We focus on the home network, and treat the issue in three stages. We examine latency variation and queueing delay on the public internet and show that significant excess delay is often present. Then, we evaluate several modern AQM algorithms and packet schedulers in a residential setting, and show that modern AQMs can almost entirely eliminate bufferbloat and extra queueing latency for wired connections, but that they are not as effective for WiFi links. Finally, we go on to design and implement a solution for bufferbloat at the WiFi link, and also design a workable scheduler-based solution for realising airtime fairness in WiFi. Also included in this thesis is a description of Flent, a measurement tool used to perform most of the experiments in the other papers, and also used widely in the bufferbloat community.

Kollektivtrafik som transformativ kraft för levande och hållbara städer

Denna studie uppmärksammar kollektivtrafik som transformativ förändringskraft i städer. I studien talas om att se kollektivtrafik som ryggraden i hållbar mobilitet och en möjliggörare för förändring, med visionen att bygga en stad för människor. En levande och attraktiv stad där kollektivtrafik sätts in i ett större sammanhang för att underlätta människors vardag.  Sveriges tre största stadsregioner; Stockholm, Göteborg och Malmö har studerats. För att på ett djupare plan förstå dessa förändringsprocesser har även sju internationella jämförelsestudier tagits fram (Freiburg, Zürich, London, Paris, Singapore, Kapstaden och Buenos Aires), liksom en konceptuell och teoretisk analys- och tolkningsram. Såväl de svenska som utländska fallstudierna pekar på att det finns många utmaningar i växande stadsregioner.  Studien ger en ökad insikt om att kollektivtrafik kan vara ett verktyg att bryta sociala och miljömässiga utmaningar, liksom mobilitetsutmaningar. Det krävs en avancerad produktionslogik för att utveckla kapacitetsstarka kollektivtrafiklösningar, men när allt är på plats i ett samverkande system kan kunden/resenären utnyttja systemet i sin egen värdeskapande process utifrån en kundorienterad tjänstelogik. Det finns ett behov av en fortsatt lärprocess för att använda kollektivtrafik som transformativ kraft. Det är människor som rör sig i staden, kollektivtrafik är endast ett medel. Det är med gemensamma offentliga och privata resurser som en levande, hållbar och attraktiv livsmiljö kan skapas, men det måste ske inom ramen gemensamma värderingar och berättelser.  Då utvecklas ett samhälle som bygger på tillit. Att hantera transformation, värdeskapande och hållberhet kräver flernivåstyrning, resursintegration och en utmaningsdriven tjänsteinnovation. Delarna finns där, men det behövs ett mer samlat grepp för att fullt ut utnyttja potentialen i Kollektivtrafik som transformativ kraft för levande och hållbara städer.

Effects of plasticizing and crosslinking on the mechanical and barrier properties of coatings based on blends of starch and poly(vinyl alcohol)

In the last decades, intensive research has been carried out in order to replace oil-based polymers with bio-based polymers due to growing environmental concerns. So far, most of the barrier materials used in food packaging are petroleum-based materials. The purpose of the barrier is to protect the packaged food from oxygen, water vapour, water and fat. The mechanical and barrier properties of coatings based on starch-plasticizer and starch-poly(vinyl alcohol) (PVOH)-plasticizer blends have been studied in the work described in this thesis. The plasticizers used were glycerol, polyethylene glycol and citric acid. In a second step, polyethylene coatings were extruded onto paperboard pre-coated with a starch-PVOH-plasticizer blend. The addition of PVOH to the starch increased the flexibility of the film. Curing of the film led to a decrease in flexibility and an increase in tensile strength. The flexibility of the starch-PVOH films was increased more when glycerol or polyethylene glycol was added than citric acid. The storage modulus of the starch-PVOH films containing citric acid increased substantially at high temperature. It was seen that the addition of polyethylene glycol or citric acid to the starch-PVOH blend resulted in an enrichment of PVOH at the surface of the films. Tensile tests on the films indicated that citric acid acted as a compatibilizer and increased the compatibility of the starch and PVOH in the blend. The addition of citric acid to the coating recipe substantially decreased the water vapour transmission rate through the starch-PVOH coated paperboard, which indicated that citric acid acts as a cross-linker for starch and/or PVOH. The starch-PVOH coatings containing citric acid showed oxygen-barrier properties similar to those of pure PVOH or of a starch-PVOH blend without plasticizer when four coating layers were applied on a paperboard. The oxygen-barrier properties of coatings based on a starch-PVOH blend containing citric acid indicated a cross-linking and increase in compatibility of the starch-PVOH blends. Polyethylene extrusion coating on a pre-coated paperboard resulted in a clear reduction in the oxygen transmission rate for all the pre-coating formulations containing plasticizers. The addition of a plasticizer to the pre-coating reduced the adhesion of polyethylene to pre-coated board. Polyethylene extrusion coating gave a board with a lower oxygen transmission rate when the paperboard was pre-coated with a polyethylene-glycol-containing formulation than with a citric-acid-containing formulation. The addition of polyethylene glycol to pre-coatings indicated an increase in wetting of the pre-coated paperboard by the polyethylene melt, and this may have sealed the small defects in the pre-coating leading to low oxygen transmission rate. The increase in brittleness of starch-PVOH films containing citric acid at a high temperature seemed to have a dominating effect on the barrier properties developed by the extrusion coating process. 

Att studera vidare eller inte det är frågan : 2 321 gymnasisters funderingar kring högre studier

I takt med att konkurrensen blir allt hårdare om att rekrytera studenter till grundutbildningar på svenska universitet och högskolor har intresset att ta reda på vad studenter och gymnasister tycker och tänker om högre utbildning ökat. Vid Karlstads universitet har vi sedan många år kartlagt vad våra nuvarande studenter tycker om sin utbildning. När det gäller gruppen framtida studenter i form av gymnasister har vi tidigare inte på motsvarande sätt systematiskt sätt undersökt hur de ser på högre utbildning. Som ett första steg i ett sådant arbete har vi under läsåret 2006/2007 genomfört tre enkätundersökningar där gymnasisters inställning till högre studier analyserats. Två grupper av studenter har under hösten 2006 skrivit sina examensarbeten med detta tema och baserat på dessa studier har vi under våren 2007 samlat in en större enkät i samband med att alla gymnasister i regionen bjudits in till information om högre utbildning på universitetet i Karlstad.

Changing the servicescape : The influence of music, self-disclosure and eye gaze on service encounter experience and approach-avoidance behavior

The purpose of this thesis is to investigate and understand the effect of a servicescape’s ambient and social conditions on consumers’ service encounter experience and their approach/avoidance behavior in a retail context. In three papers, with a total sample of over 1600 participants (including 550 actual consumers) and seven experiments, the author investigates the effect of music (ambient stimuli), employees’ self-disclosure (verbal social stimuli) and employees’ gazing behavior (nonverbal social stimuli) on consumers’ service encounter experience and approach/avoidance behavior in a retail store. Paper I comprised two experiments, and the aim was to investigate the influence of music on emotions, approach/avoidance behavior. Paper II comprised two experiments, and the aim was to investigate the effect of frontline employees’ personal self-disclosure on consumers’ reciprocal behavior. Paper III comprised three experiments, and the aim was to investigate the influence of employee’s direct eye gaze/ averted eye gaze on consumer emotions, social impression of the frontline employee and encounter satisfaction in different purchase situations. The results in this thesis show that music affects consumers in both positive and negative ways (Paper I). Self-disclosure affects consumers negatively, in such a way that it decreases encounter satisfaction  (Paper II) and, finally, eye gaze affects consumers by regulating both positively – and in some cases also negatively – consumers’ social impression of the frontline employee and their encounter satisfaction (Paper III). The conclusions of this thesis are that both ambient and social stimuli in a servicescape affect consumers’ internal responses, which in turn affect their behavior. Depending on the purchase situation, type of retail, and stimuli, the internal and behavioral responses are different.

Secure and Privacy-aware Data Collection and Processing in Mobile Health Systems

Healthcare systems have assimilated information and communication technologies in order to improve the quality of healthcare and patient's experience at reduced costs. The increasing digitalization of people's health information raises however new threats regarding information security and privacy. Accidental or deliberate data breaches of health data may lead to societal pressures, embarrassment and discrimination. Information security and privacy are paramount to achieve high quality healthcare services, and further, to not harm individuals when providing care. With that in mind, we give special attention to the category of Mobile Health (mHealth) systems. That is, the use of mobile devices (e.g., mobile phones, sensors, PDAs) to support medical and public health. Such systems, have been particularly successful in developing countries, taking advantage of the flourishing mobile market and the need to expand the coverage of primary healthcare programs. Many mHealth initiatives, however, fail to address security and privacy issues. This, coupled with the lack of specific legislation for privacy and data protection in these countries, increases the risk of harm to individuals. The overall objective of this thesis is to enhance knowledge regarding the design of security and privacy technologies for mHealth systems. In particular, we deal with mHealth Data Collection Systems (MDCSs), which consists of mobile devices for collecting and reporting health-related data, replacing paper-based approaches for health surveys and surveillance. This thesis consists of publications contributing to mHealth security and privacy in various ways: with a comprehensive literature review about mHealth in Brazil; with the design of a security framework for MDCSs (SecourHealth); with the design of a MDCS (GeoHealth); with the design of Privacy Impact Assessment template for MDCSs; and with the study of ontology-based obfuscation and anonymisation functions for health data.

Increasing the value of household appliances by adding a heat pump system

Historically, domestic tasks such as preparing food and washing and drying clothes and dishes were done by hand. In a modern home many of these chores are taken care of by machines such as washing machines, dishwashers and tumble dryers. When the first such machines came on the market customers were happy that they worked at all! Today, the costs of electricity and customers’ environmental awareness are high, so features such as low electricity, water and detergent use strongly influence which household machine the customer will buy. One way to achieve lower electricity usage for the tumble dryer and the dishwasher is to add a heat pump system. The function of a heat pump system is to extract heat from a lower temperature source (heat source) and reject it to a higher temperature sink (heat sink) at a higher temperature level. Heat pump systems have been used for a long time in refrigerators and freezers, and that industry has driven the development of small, high quality, low price heat pump components. The low price of good quality heat pump components, along with an increased willingness to pay extra for lower electricity usage and environmental impact, make it possible to introduce heat pump systems in other household products. However, there is a high risk of failure with new features. A number of household manufacturers no longer exist because they introduced poorly implemented new features, which resulted in low quality and product performance. A manufacturer must predict whether the future value of a feature is high enough for the customer chain to pay for it. The challenge for the manufacturer is to develop and produce a high-performance heat pump feature in a household product with high quality, predict future willingness to pay for it, and launch it at the right moment in order to succeed. Tumble dryers with heat pump systems have been on the market since 2000. Paper I reports on the development of a transient simulation model of a commercial heat pump tumble dryer. The measured and simulated results were compared with good similarity. The influence of the size of the compressor and the condenser was investigated using the validated simulation model. The results from the simulation model show that increasing the cylinder volume of the compressor by 50% decreases the drying time by 14% without using more electricity.  Paper II is a concept study of adding a heat pump system to a dishwasher in order to decrease the total electricity usage. The dishwasher, dishware and water are heated by the condenser, and the evaporator absorbs the heat from a water tank. The majority of the heat transfer to the evaporator occurs when ice is generated in the water tank. An experimental setup and a transient simulation model of a heat pump dishwasher were developed. The simulation results show a 24% reduction in electricity use compared to a conventional dishwasher heated with an electric element. The simulation model was based on an experimental setup that was not optimised. During the study it became apparent that it is possible to decrease electricity usage even more with the next experimental setup.

The initial phase of sodium sulfite pulping of softwood : A comparison of different pulping options

Single stage and two-stage sodium sulfite cooking were carried out on either spruce, pine or pure pine heartwood chips to investigate the influence of several process parameters on the initial phase of such a cook down to about 60 % pulp yield. The cooking experiments were carried out in the laboratory with either a lab-prepared or a mill-prepared cooking acid and the temperature and time were varied. The influences of dissolved organic and inorganic components in the cooking liquor on the final pulp composition and on the extent of side reactions were investigated. Kinetic equations were developed and the activation energies for delignification and carbohydrate dissolution were calculated using the Arrhenius equation. A better understanding of the delignification mechanisms during bisulfite and acid sulfite cooking was obtained by analyzing the lignin carbohydrate complexes (LCC) present in the pulp when different cooking conditions were used. It was found that using a mill-prepared cooking acid beneficial effect with respect to side reactions, extractives removal and higher stability in pH during the cook were observed compared to a lab-prepared cooking acid. However, no significant difference in degrees of delignification or carbohydrate degradation was seen.  The cellulose yield was not affected in the initial phase of the cook however; temperature had an influence on the rates of both delignification and hemicellulose removal. It was also found that the  corresponding activation energies increased in the order:  xylan, glucomannan, lignin and cellulose. The cooking temperature could thus be used to control the cook to a given carbohydrate composition in the final pulp. Lignin condensation reactions were observed during acid sulfite cooking, especially at higher temperatures. The LCC studies indicated the existence of covalent bonds between lignin and hemicellulose components with respect to xylan and glucomannan. LCC in native wood showed the presence of phenyl glycosides, ϒ-esters and α-ethers; whereas the α-ethers  were affected during sulfite pulping. The existence of covalent bonds between lignin and wood polysaccharides might be the rate-limiting factor in sulfite pulping.

Significant history and historical orientation : Ugandan students narrate their historical pasts

In 2012, Uganda celebrated 50 years of independence. The postcolonial era in the country has been marked by political turmoil and civil wars. Uganda, like many other postcolonial states in Africa, cannot be described as an ethnically or culturally homogenous state. However, history education has globally been seen as a platform for constructing national identities in contemporary societies. At the same time, it is assumed that specific historical experiences of countries influence historical understanding. This study takes its starting point in the theories of historical consciousness and narrativity. A narrative could be viewed as a site where mobilization of ideas of the past to envisage the present and possible futures is made and hence the narrative expresses historical orientation. Through the concept of historical orientation historical consciousness can be explored, i.e. what history is viewed as significant and meaningful. The aim in the study is to explore in what ways students connect to their historical pasts.   The study explores 219 narratives of 73 Ugandan upper secondary students. Narratives elicited through written responses to three assignments. Designed to capture different approaches to history: either to start from the beginning and narrate history prospectively or to depart from the present narrating retrospectively. The colonial experience of Uganda affected the sampling in the way that students were chosen from two different regions, Central and Northern Uganda. The comparison was a way to handle the concept of ‘nation’ as a presupposed category. Narrative analysis has been used as a method to explore what the students regarded as historically significant and what patterns among the narratives that point towards particular historical orientations.   The empirical results show how different approaches to history, a prospective or a retrospective approach, influence the student narratives. For instance, valued judgments on past developments were more common with the retrospective approach. The results also show differences in evaluating past developments according to regional origin. Students from northern Uganda were generally more inclined to tell a story of decline. Also, it is argued that the student narratives were informed by a meta-narrative of Africa. It was as common to identify oneself as African as it was to identify as Ugandan.

Regionen och EU? : Uppfattningar och attityder till EU-relaterade frågor i Västsverige

This thesis explores perceptions and preferences on regional action in EU-related frameworks among regional actors in Western Sweden. Building upon the literature on Europeanisation and the Fusion approach, three dimensions of Europeanisation are clarified and explored– download, upload and crossload – and together with a set of five variables that constitute the Micro Fusion Framework; a comprehensive analytical tool is developed. The thesis analyses the intense debate among the members of West Sweden that took place from 2011 to 2013 that focused on how to functionally organise the regional office in Brussels in order to meet future challenges. Surprisingly, the members eventually decided to terminate their cooperation and close the jointly owned office in Brussels in spite of the fact that it has been widely regarded as successful and effective. Diverging perceptions and preferences is understood in terms of three positions on regional action; a download-, upload- and a coherent oriented position. Finally, the thesis presents the empirical findings and discusses in relation to three fusion scenarios, infusion, defusion and clustered fusion. In terms of Micro Fusion Framework, the dynamics shaping why West Sweden was finally regarded as a dysfunctional arena for regional action are explained by a shift of attention and action among regional actors in Western Sweden that led to pressure for further institutional adaptation in order to meet the demand of how ‘to get the best out of the EU’. Further, this redefinition of how to handle EU-affairs within the upload-oriented position was accompanied by positive attitudes towards the potential to bypass the state and thereby pursue regional priorities directly in Brussels given the compound nature of the EU. In contrast, those regional actors that are found to be more download-oriented often question the benefits of uploading activities in practice and advocate close relations to the state. A coherent oriented position recognises the importance of activities related to both of the vertical dimensions of Europeanisation.
