    “Oh It Was a Woman! Had I Known I Would Have Reacted Otherwise!”: Developing Digital Methods to Switch Identity-Related Properties in Order to Reveal Linguistic Stereotyping2019Ingår i: Virtual Sites as Learning Spaces: Critical Issues on Languaging Research in Changing Eduscapes / [ed] Sangeeta Bagga-Gupta, Giulia Messina Dahlberg and Ylva Lindberg, England: Palgrave Macmillan, 2019, 1, s. 207-239Kapitel i bok, del av antologi (Refereegranskat)
    Abstract [en]

    This chapter describes the methodological processes involved in the project Raising Awareness using Virtual Experiencing (RAVE), funded by the Swedish Research council. The aim of the project is to develop experiential pedagogic approaches aimed at raising sociolinguistic language awareness about stereotyping and language. A key feature of the method consists of updated matched-guise techniques, whereby the same recording is digitally manipulated to alter the voice quality of a speaker to sound “male” or “female”, for example. These versions of the recording are then used as input stimuli for a response phase aimed at illustrating how we as listeners react differently to a person, and what is being said, depending on the perceived identity of the speaker. This chapter then illustrates how results are used as a starting point for discussions with respondents (student groups) on issues related to stereotyping and language, with the aim to raise awareness and self-reflection.

    Life Is Strange and “Games Are Made”: A Philosophical Interpretation of a Multiple-Choice Existential Simulator With Copilot Sartre2018Ingår i: Games and Culture: A Journal of Interactive Media, ISSN 1555-4120, E-ISSN 1555-4139, Vol. 8, nr 1, s. 825-842Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The multiple-choice video game Life is Strange was described by its French developers as a metaphor for the inner conflicts experienced by a teenager in trying to become an adult. In psychological work with adolescents, there is a stark similarity between what they experience and some concepts of existentialist philosophy. Sartre’s script for the movie Les Jeux Sont Faits (literally “games are made”) uses the same narrative strategy as Life is Strange—the capacity for the main characters to travel back in time to change their own existence—in order to stimulate philosophical, ethical, and political thinking and also to effectively simulate existential “limit situations.” This article is a dialogue between Sartre’s views and Life is Strange in order to examine to what extent questions such as what is freedom? what is choice? what is autonomy and responsibility? can be interpreted anew in hybrid digital–human—“anthrobotic”—environments.

    Big Data, Small Concepts: Histosophy as an Approach to Longue-Durée History2019Ingår i: Global l Intellectual History, ISSN 2380-1883Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In this essay, we sketch out a method, histosophy, which makes possible the study of intellectual history and conceptual genealogy both in depth and over long periods of time. Histosophy uses digital tools to survey ‘large issues within small compasses.’ A genealogy of signifiers, it considers metonymic parts of a problem in order to contribute precisely and coherently to a larger perspective. We outline the theoretical contours of our approach. We exemplify how it works in practice by looking at the signifier ‘esprit de corps’, the study of which is presented in detail in the histosophical book The Genealogy of Esprit de Corps(Edinburgh University Press, 2019). The phrase ‘esprit de corps’ has been widely used since the eighteenth century in different discourses (political, military, sociological, etc.), but it is sufficiently limited that its genealogy can be traced across centuries and nations with precision, coherence, clarity, and with the help of automated search engines. By contrast, related but bigger concepts like freedom, individualism or solidarity are part of dozens of disparate and fuzzy discourses, so often uttered that the analysis of modern uses is problematic. The histosophical methodology is applicable in six discrete stages, here outlined.

    Överskuldsättning för privatpersoner och företag2018Samlingsverk (redaktörskap) (Övrigt vetenskapligt)
    Abstract [sv]

    Akademien för insolvensrätt på Handelshögskolan vid Karlstads universitet samlar kompetens från juridik, ekonomi och andra ämnen för att utveckla och stärka forskning, utbildning och samverkan kring ämnet insolvensrätt. Akademien för insolvensrätt har bildats för att öka fokus på insolvensrätt och förbättra förutsättningarna för tvärvetenskap mellan rättsvetenskap och företagsekonomi och andra ämnen.

     

    Akademien har inrättat en skriftserie som utkommer med två böcker om året med olika teman. Skriftseriens första bok har temat överskuldsättning. Många människor lever med skulder som de saknar förutsättningar att kunna betala tillbaka. Om fler kan få sina skulder sanerade innebär det en lättnad inte bara för de skuldsatta och deras familjer, utan även för borgenärerna och samhället i stort. Den 21–22 september 2017 hölls en två-dagars tvärvetenskaplig konferens om överskuldsättning där bl.a. ämnena juridik, ekonomi och socialt arbete medverkade. På konferensen behandlades flera teman; Konsumentskydd och kreditgivning i ett juridiskt perspektiv. Konsumentverkets arbete mot överskuldsättning. Kronofogdens förebyggande arbete med fokus på barn och unga. Överskuldsättning och jämlikhet i ett ekonomiskt perspektiv. Företagsrekonstruktion och lagarna om skuldsanering för privatpersoner och företagare samt avslutningsvis Skuldsatt och skamsen i ett socialt perspektiv. Boken består av två delar. I den första delen återfinns de föredrag som hölls på konferensen med därtill hörande Power-Points. Den andra delen är en antologi med artiklar om skuldsanering och företagsrekonstruktion som tidigare har publicerats i Insolvensrättslig Tidskrift.

    Routes and roots to knowing in Shaun White’s snowboarding road trip: A mycorrhizaic approach to multisensory emplaced learning in exergames2019Ingår i: Scandinavian Sport Studies Forum, ISSN 2000-088X, E-ISSN 2000-088X, Vol. 10, s. 251-278Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This article explores learning during game-play of a snowboarding video game intrigued by questions raised in the wake of the increasing mediatisation and digitisation of learning. Correspondingly, we answer to calls for more suitable metaphors for learning to cater for the entangled learning processes that changes related to the increase of digital media may infer. Using a short term sensory ethnography approach, we elaborate on the idea of multisensory emplaced learning and propose an organic metaphor – mycorrhiza – to both methodology and learning. Mycorrhiza refers to a symbiotic relationship between fungi and roots of plants in its environment where fungi are the visible effects of the mycorrhiza. The metaphor provides a way to start to unpack sensory, visual and embodied aspects of learning in the complexities of the digital age. By elaborating on the mycorrhizaic concepts fungus, soil, growth, mycelia and symbiosis we show three interrelated ways of moving through this game: (i) a social and cultural route, (ii) a competitive route, and (iii) an experiential route. With help of the metaphor we discern the symbiotic relations between what appeared in our empirical material as visual and other human and non-human aspects of emplacement.

    Musikens medialisering och musikaliseringen av medier och vardagsliv i Sverige2019Samlingsverk (redaktörskap) (Refereegranskat)
    Abstract [sv]

    Musiken har genomgått en medialisering utan like de senaste hundra åren. Elektrifiering och digitalisering av musikmedierna har inneburit att musik kan höras så gott som överallt och när som helst. Vid sidan av medialisering introducerar föreliggande antologi begreppet musikalisering. Medan medialisering handlar om mediernas långsiktiga påverkan på vardagspraktiker och kommunikation, handlar musikalisering om förändringar i musikens roll. Förutom att vara en naturlig komponent i allt fler vardagssammanhang bidrar musik i allt högre grad till att strukturera och organisera uppfattningar om, erfarenheter av och förväntningar på den levda verkligheten.

    Klädsam autenticitet: Om det äkta som resurs och vara2019Ingår i: Sakprosa, ISSN 1502-6000, E-ISSN 1891-5108, Vol. 11, nr 7, s. 1-34Artikel i tidskrift (Refereegranskat)
    Abstract [sv]

    Den här artikeln handlar om hur föreställningar om ursprungsfolk rekontextualiseras i kommersiella sammanhang. Konkret undersöks hur ett svenskt jeansmärke marknadsför sina jeans som ’autentiska’ och ’samiska’. Artikeln syftar till att utforska autenticitet som diskursiv praktik och att diskutera hur förledet sak- gör det möjligt att inkludera sakprosatexter och andra semiotiska material i analysen av autenticitet. Studien bygger på socialsemiotisk teori och tillämpar proveniens och affordans som analytiska begrepp. Analysen visar hur bl.a. flerspråkighet, ikonografi, tygvikt och materialval realiserar ’samisk’ autenticitet såväl som en kontextspecifik ’global’ jeansautenticitet. Genom att visa hur föreställningar om autenticitet omlokaliseras och återuppfinns, bidrar artikeln till förståelse för den semiotiska process då ursprungsfolk i allmänhet och samer i synnerhet omdefinieras som ekonomisk resurs inom den nya, globala ekonomin.

    Language use in the teaching of human rights2019Ingår i: Cogent Education, E-ISSN 2331-186X, Vol. 6, nr 1, artikel-id 1683932Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This research seeks to increase the knowledge about the role of language in the teaching of human rights. The specific interest is to examine how language use extends and specifies the human rights learning situation. Drawing on John Dewey’s arguments for two main constituents of an educative language use—the extension of vocabulary and rendering it more precise, observational data from ongoing human rights teaching in six Swedish classes in Years 2–3, 5 and 8 are analysed. The findings show six focal points towards which the language use in the teaching extends the students’ vocabulary and generic understanding of human rights, and three objectives for an increased preciseness in students’ language. The paper highlights differences between the age groups concerning the focal points and precision objectives, and points out potentials and strengths in the observed teaching, as well as aspects of problematic character to consider further.

    Organisering av ideellt arbete: En studie om hur det ideella arbetet organiseras i projektfinansierade av Arvsfonden 2016–20192019Rapport (Övrigt vetenskapligt)
    Abstract [sv]

    Engagemang i oavlönat ideellt arbete är ett globalt fenomen som historiskt sett skiljer sig åt mellanländer, både när det gäller hur engagemanget ser ut och hur många som engagerar sig. Sverige harlänge haft en stark civil sektor, och tillgången på ideella har stor betydelse för många organisationersöverlevnad – såväl nationella som internationella. Samtidigt talas det ofta om att det har blivitsvårare och svårare att få tag på ideella, men är det verkligen så? I Sverige visar undersökningar att andelen som gör ideella insatser är stabil och att det till och med går att se positiva trender.

    Så varför är den allmänna uppfattningen att det är svårare att få tag på ideella? En möjlig förklaring kan vara den trend som syns i både den svenska och internationella forskningen, nämligen attmänniskor är ideella på ett annat sätt numera. Tidigare var människor ofta engagerade i sammaorganisation under en längre tid. Nu gör de snarare gör kortare inhopp som ideella, till exempel som volontär i flera insatser drivna av olika organisationer.

    Den här trenden kommer att påverka hur vi människor organiserar vårt samhälleliga engagemang iframtiden. När lika många vill göra ideella uppdrag men på ett annat sätt, behöver vi även ändraorganiseringen av det ideella arbetet – en förändring som redan har börjat.Därför har den här studien undersökt hur det ideella arbetet organiseras i projekt som har fåttpengar från Arvsfonden under perioden 2016 till 2019. Resultatet baseras på enkätsvar från 181 projekt, ansökningar och rapporteringar från 20 projekt samt besök hos och intervjuer med projektledning och ideella i 4 projekt.

    Studiens resultat visar att hur man definierar och benämner de ideella verkar ha betydelse för vilka som är de ideella i ett visst projekt. Vilka de ideella är verkar också ha att göra med hur man är ideell.

    Olika typer av ideellt arbete görs av olika människor, som har skilda motiv och verkar på olika arenor. Det ideella arbetet betyder därmed olika saker för olika organisationer och människor. De ideella personernas arbetsuppgifter i projekten är lika skilda och varierade som projekten i sig. Personernaär också engagerade i olika grad: vissa är endast med i enskilda punktinsatser, medan andra ”gör allt” i projektet. De ideella uppdragen kan göras i sociala organisationer och idrottsorganisationer inomden civila sektorn, men även som en del av någons ordinarie tjänst inom offentlig eller privat sektor.

    Dessa skillnader mellan ideella har betydelse för exempelvis vilken utbildning de behöver, vad deönskar för uppskattning och hur de bör rekryteras. Organisationer kan till exempel använda olika strategier för rekrytering beroende på vilka de vill rekrytera och vilka uppgifter de ideella ska utföra.Vilka de ideella är har också betydelse för hur det ideella arbetet bör organiseras.

    I den här rapporten diskuteras hur organiseringen av ideella påverkas av relationen mellan anställda och ideella i en organisation, olika typer av organisationer och olika former av ideella. I slutet avrapporten presenteras också en modell för hur ideellt arbete skulle kunna organiseras för att bli merhållbart. Modellen innebär i korthet att projekt eller organisationer samverkar i organiseringen av ideellt arbete.

    Hur projekt organiserar ideellt arbete har stor betydelse för vilka spår projekten lämnar hos olika målgrupper, däribland de ideella själva. Det påverkar också projektens överlevnad. Arvsfonden kanhjälpa organisationer att planera sitt arbete genom att efterfråga tydligare beskrivningar och tankarom organiseringen av ideellt arbete. Det kan i sin tur öka möjligheterna för projekten att överleva även efter projekttidens slut.

    Global governance for climate justice: A cross-national analysis of CO2 emissions2019Ingår i: Global Transitions, ISSN 2589-7918, Vol. 1, s. 190-199Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Sustainable energy transitions are key to achieving climate justice for all. Carbon dioxide emissions’(CO2) unequal distribution globally is one of the many issues preventing climate justice. Efforts to reduceglobal CO2impacts are vital for environmental justice efforts and a future free from climate change is-sues. Researchers have long been interested in how the rise of global governance initiatives, such asmultilateral treaties, impact environmental outcomes across the world. However, little is known abouthow global governance concerning energy usage and technologies impacts CO2emissions across theworld. Using two-wayfixed effects regression analysis from 1996 to 2011, we test how 24 multilateralenvironmental treaties with an energy focus impact CO2emissions per capita, CO2emissions as a per-centage of gross domestic product, and total CO2emissions for 162 nations. The multilateral energytreaties were collected from Ecolex. This analysis assesses how the legitimacy of global contracts mayimpact actual decreases in CO2emissions, resulting in climate justice outcomes. Additionally, thisanalysis considers how factors of institutional state governance, including control of corruption, rule oflaw, political stability, government effectiveness, and regulatory quality moderate the impact of multi-lateral energy environmental treaties and CO2emissions. Wefind that stocks of environmental treatyratification are associated with decreases in all three types of CO2emissions. Renewable energy con-sumption, GDP per capita, and urban and total population are associated with increased CO2 emissions.We alsofind some support for the idea that treaties are associated with larger decreases in emissions innations with higher levels of state governance. Understanding how state accountability, transparency,and legitimacy factor into the effectiveness of multilateral environmental treaties on reducing CO2emissions is essential to combating climate change issues.

    Embodying latinness in Australia through dance2019Ingår i: Revista Tempos e Espaços em Educação, ISSN 1983-6597, E-ISSN 2358-1425, Vol. 12, nr 31, s. 81-96Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Dance, as an embodied activity, is shaped by culture, and simultaneously shapes culture. Significantly, over the last few years there has been a worldwide boom in Latin dance, which is often considered an ‘exotic’ and ‘sexy’ activity. This paper explores experiences of teaching Latin dance as a service activity (extensión, in Spanish) by an academic in Australia, shaped by the theoretical ideas of public and body pedagogies. The reflections are presented under two broad themes: the potential of Latin dance as a service activity, and the processes of integrating and othering Latinness in Australia.

    Making mythopoeic meaning out of plants2019Ingår i: Cogent Arts and Humanities, E-ISSN 2331-1983, Vol. 6, nr 1, artikel-id 1687256Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The article discusses literary and scientific discourse in relation to plant cognition. I argue that one purpose of literature is to let humans make meaning out of their environment. My focus is not on literature as fiction, or any a priori faculty of counterfactual construction. Rather, I consider literature as the inspired response to external phenomena. In this aspect, literature springs from outside; and this it shares with scientific explanation. But where science lays bare the mechanical laws of the universe, literature operates with compelling narratives of individual wills. I further suggest that the literary mode is specifically suited for envisioning non-human life. Poetic thought is considered as a mode of human cognition that, by suspending the distance between human and world, allows us to think modes of non-human cognition. In literature, we are able to represent those affects we share with other forms of biological life. My focus is on two literary representations of plant life and the blending of life forms in stories where people turn into plants. I start by considering how a few botanists have taken the literary mode as a negative point of departure for their attempts to explain plant behavior. Then, I muster two theoretical accounts in order to read two such stories. Henri and Henriette Frankfort’s description of mythopoeic thought is used as the starting point for an interpretation of Ovid’s take on the myth of Echo and Narcissus; and Roger Caillois’ “comparative biology” for a reading of Johan Borgen’s short story “Kaprifolium”.

    Promoting integration through physical education (?)2019Ingår i: Sport, Education and Society, ISSN 1357-3322, E-ISSN 1470-1243, s. 1-14Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    A common problem in contemporary western societies is segregation,which is also reflected in schools. The point of departure for this study is apolitical initiative in Sweden, where pupils are being transported by busfrom a suburb to different schools in the city with the aim of promotingintegration and improved performance results. The study focuses on theteaching practice of Physical Education (PE) at one of the schools where‘the bus for inclusion’ stops every morning. The research questionconcerns how ‘the political action’ of the bussing project is ‘acted upon’in the subject of PE. The purpose is to explore what becomes of thisparticular PE practice, in terms of rationalities encompassing a PEteacher’s pedagogical actions and the pupils’ ways of acting on them. Thedata, gathered through extensive fieldwork, including lesson observationsand interviews, is analysed from a governmentality perspective [Foucault,1978/1994. Governmentality. In Power (pp. 201–222). New York: The NewPress]. The findings highlight three underlying rationalities in regards tointegration, aiming at promoting intercultural encounters, collaborationand mutual respect. These rationalities, manifested through the PEteacher’s pedagogical actions, offer guidance for the pupil seen as ‘asubject seeking to construct himself or herself’ [Wieviorka 2014. A critiqueof integration. Identities, 21(6), 633–641, 636–637]. In case of compliance,the notion of ‘us and them’ is countered and a shared experience ofbelonging is achieved through teamwork and self-regulation. In case ofresistance, segregation is maintained in the school community as well asin society as a whole. This study does not contribute any incontestableevidence of social inclusion through PE [cf. Bailey, 2005. Evaluating therelationship between physical education, sport and social inclusion.Educational Review, 57(1), 71–90; Dagkas, 2018. Is social inclusion throughPE, sport and PA still a rhetoric? Evaluating the relationship betweenphysical education, sport and social inclusion. Educational Review, 70(1),67–74]. However, the findings indicate that ‘action upon action’ in aculturally heterogeneous PE practice makes a difference insofar asintegration is understood as a process of subjectivation [Wieviorka 2014.A critique of integration. Identities, 21(6), 633–641]. Depending on thedirection of the PE teacher’s guidance, the process might tend towardseither cultural assimilation or pluralistic integration [Grimminger, 2008.Promoting intercultural competence in the continuing education ofphysical education teachers. Sport-Integration-Europe, 310–320].

    Ethylene mediates the branching of the jasmonate-induced flavonoid biosynthesis pathway by suppressing anthocyanin biosynthesis in red Chinese pear fruits2019Ingår i: Plant Biotechnology Journal, ISSN 1467-7644, E-ISSN 1467-7652Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Flavonoid accumulation in most fruitsis enhanced by ethylene and jasmonate. However, little is known about the hormone functions related to red pear fruit coloration or their combined effects and potential underlying mechanisms. Various treatments were used to investigate the flavonoid metabolite profile and pear transcriptome to verify the effects of ethylene and jasmonate on flavonoid biosynthesis in red pear fruits as well as the mechanism behind this. Ethylene inhibits anthocyanin biosynthesis in red Chinese pear fruits, whereas jasmonate increases anthocyanin and flavone/isoflavone biosyntheses. The branching of the jasmonate-induced flavonoid biosynthesis pathway is determined by ethylene. Co-expression network and Mfuzz analyses revealed 4,368 candidate transcripts. Additionally, ethylene suppresses PpMYB10 and PpMYB114 expression via TF repressors, ultimately decreasing anthocyanin biosynthesis. Jasmonate induces anthocyanin accumulation through transcriptional or post-translational regulation of TFs like MYB and bHLH in the absence of ethylene. However, jasmonate induces ethylene biosynthesis and the associated signaling pathway in pear, thereby decreasing anthocyanin production, increasing the availability of the precursors for flavone/isoflavone biosynthesis, and enhancing deep yellow fruit coloration. We herein present new phenotypes and fruit coloration regulatory patterns controlled by jasmonate and ethylene, and confirm that the regulation of fruit coloration is complex.

    Mean Propulsive Velocity Is a Viable Method for Adjusting the Resistance-Training Load at Moderate Altitude: Monitoring Resistance Load at Altitude2019Ingår i: Frontiers in Sports and Active Living, E-ISSN 2624-9367, Vol. 1, artikel-id 52Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We examined the viability of using mean propulsive velocity (MPV) to adjust the load in the countermovement jump (CMJ) at moderate altitude. Twenty-four volunteers were assigned to a 4-week power-oriented resistance training (RT) program in either normoxia (N, 690 m) or intermittent hypobaric hypoxia (IH, 2,320 m). The load was adjusted to maintain execution velocity of CMJ at 1m·s−1 of MPV. Relative peak power output (Prel), and percentage of velocity loss throughout the sets (VL) were determined for each session. The internal load was measured by the rating of perceived exertion (RPE). The absolute load lifted was higher in IH compared to N (75.6 ± 8.4 vs. 58.5 ± 12.3 kg P < 0.001). However, similar relative increases for both groups were found when comparing the final values (IH: 8.2%, P = 0.007; N: 9.8%, P = 0.03) with no changes in VL between groups (P = 0.36). Post-study Prel improved significantly only in IH (+7% W·kg−1P = 0.002). Mean RPE was greater in IH vs. N (6.8 ± 1.5 vs. 5.6 ± 2, P < 0.001). The MPV seems to be a viable method for adjusting external load during RT at moderate altitude. However, given that RT at moderate altitude increases RPE, it is prudent to monitor internal load when using the MPV to best determine the actual physiological stress of the session.

    Early assessment in mathematics, the ethics in a practice close research approach2019Ingår i: Abstractbok, 2019Konferensbidrag (Refereegranskat)
    Abstract [en]

    One of the latest reforms to increase the equity and quality in mathematics education is mandatory national assessment in Preschool-class. It is supposed to govern the action, focus and professional language of the pedagogues. In an earlier study of preparatory work, policy decisions and assessment material, we discovered that there is a risk for schoolification of the Preschool-class, through this reform. A second risk is that students could be locked into "levels" of achievement and a third risk lies in a potential narrowing down of the curriculum (Bagger, Björklund, Vennberg, Accepted). At the same time, earlier research show that early assessment can lead to positive development for students in need of support (Vennberg & Norqvist, 2018). Deriving from our initial study of national assessment in preschool class, we have planned for a follow up project with the aim to contribute to knowledge of and developing the practice about the preschool class teacher’s work with national assessment in mathematics. During the conference we will present and discuss ethical and methodological challenges in this project. More specifically, we want to discuss what is required of practice close approaches in these ethically demanding situations of vulnerability and assessment in mathematics with young students. A key issue is the opportunities for teachers and researchers to manage the information collected during the  national assessment and handling of sensitive data, how they jointly can contribute to the development and management of the knowledge that generated about students' opportunities to learn and to demonstrate their knowledge. And finally, in what way this might contribute to assessment and teaching in mathmatics continues to have its starting points in the unique assignment of the preschool-class.

    On Making Robots Proactive2019Doktorsavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    The question addressed in this thesis is: Can we make robots proactive? Proactivity is understood as self-initiated, anticipatory action. This entails the ability to generate own goals and pursue them. Our work is based on the assumption that proactivity makes robots more acceptable in human-inhabited environments. Proactive behavior is opposed to reactive behavior which is merely responding to external events and explicit requests (by the user). We approach the question of how to make robots proactive by first identifying the necessary cognitive capabilities, how they relate and interact. We find that to enable proactive behavior one needs to bridge the gap between context, planning, acting and goal reasoning. We then propose a model of opportunity which formalizes and relates these cognitive capabilities in order to create proactivity. In order to make the model of opportunity computational we introduce a framework called equilibrium maintenance. We show formally and empirically that the framework can make robots act in a proactive way. We can make guarantees about the behavior of a robot acting based on equilibrium maintenance: we prove that given certain assumptions a system employing our framework is kept within desirable states. Equilibrium maintenance is instantiated in different scenarios, both theoretically and in practice by deploying it in a number of systems including both robots and humans. More specifically, we conduct experimental runs in simulation in the domain of robotic disaster management and we implement the framework on a real robot in a domestic environment. The latter is done by integration in different levels, from conceptual examples to closing the loop with a full robotic system. Empirical results confirm that equilibrium maintenance creates proactive behavior and leads to preferable outcomes.

    Group Work in Physical Education: Exploring the Interconnectedness of Theoretical Approaches and Practice2017Ingår i: Journal of teaching in physical education, ISSN 0273-5024, E-ISSN 1543-2769, Vol. 36, s. 50-60Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Student group work is a central feature of many contemporary pedagogical approaches to teaching physicaleducation. Despite this proliferation, our understanding of the teaching-learning dynamics inherent in groupwork remains limited and has tended to be under-theorized. The purpose of this paper was to examine differenttheoretical approaches to group work to identify similarities and differences and consequently provide insightsand recommendations into ways of using group work as a pedagogical strategy. Four theoretical approaches togroup work models were described in detail with brief empirical examples used to illustrate aspects to whicheach approach draws attention. The examination demonstrates conceptual overlap, elaboration and distinctionsbetween the theoretical approaches related to: (i) content knowledge; (ii) engaging learners; (iii) theteacher’s role; and (iv) group composition. Meta-theoretical discussions of teaching strategies such as groupwork generate important discourse on the potential for the development of effective pedagogical practice.

    Chatter Mitigation in Milling Process Using Discrete Time Sliding Mode Control with Type 2-Fuzzy Logic System2019Ingår i: Applied Sciences: APPS, ISSN 1454-5101, E-ISSN 1454-5101, Vol. 9, nr 20, artikel-id 4380Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In order to achieve a high-quality machining process with superior productivity, it is very important to tackle the phenomenon of chatter in an effective manner. The problems like tool wear and improper surface finish affect the milling process and are caused by self-induced vibration termed as chatter. A strategy to control chatter vibration actively in the milling process is presented. The mathematical modeling of the process is carried out initially. In this paper, an innovative technique of discrete time sliding mode control (DSMC) is blended with the type-2 fuzzy logic system. The proposed active controller results in a significantly high mitigation of vibration. The DSMC is linked to the time-varying gain which is an innovative approach to mitigate chattering. The theorem is laid down which validates that the system states are bounded in the case of DSMC-type-2 fuzzy. Stability analysis is carried out using Lyapunov candidate. The nonlinearities linked with the cutting forces and damper friction are handled effectively by using the type-2 fuzzy logic system. The performance of the DSMC-type-2 fuzzy concept is compared with the discrete time PID (D-PID) and discrete time sliding mode control for validating the effectiveness of the controller. The better performance of DSMC-type-2 fuzzy over D-PID and DSMC-T1 fuzzy in the minimization of milling chatter are validated by a numerical analysis approach.

    The Implementation Integrity of Parenting Programs: Which Aspects Are Most Important?2019Ingår i: Child and Youth Care Forum, ISSN 1053-1890, E-ISSN 1573-3319, Vol. 48, nr 6, s. 917-933Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: The implementation of preventive interventions is considered a crucial aspect of their success. However, few studies have investigated which components of implementation are most important.

    Objective: We aimed to understand whether the components of implementation integrity—adherence, quality of delivery, dose, and participants’ involvement—influenced the effectiveness of four parenting programs. We also investigated factors associated with these components.

    Method: Data come from a national evaluation of parenting programs in Sweden. The study was a randomised controlled effectiveness trial, with a sample of 535 parents with 3–12-year-old children. Measures included parenting behaviors (angry outbursts, harsh parenting, attempts to understand, rewarding, and praising), child conduct problems (ECBI and SNAP-V), and measures tapping into the four components (adherence, quality of delivery, dose, and participant involvement).

    Results: We ran multilevel models and found that implementation quality (adherence and quality of delivery) did not influence the effects on parents and children. Conversely, participant involvement was associated with improvements in parenting and child conduct. Finally, parents’ perceptions of their leaders as supportive and understanding were associated with parents’ responsiveness and attendance.

    Conclusions: Our study highlights the importance of having actively engaged parents to maximise intervention effects.

    What would physical educators know about movement education? A review of literature2017Ingår i: Quest (National Association for Physical Education in Higher Education), ISSN 0033-6297, E-ISSN 1543-2750, Vol. 69, nr 4, s. 419-435Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    This review article identifies the conceptual underpinnings of currentmovement research in physical education. Using a hermeneuticapproach, four analogies for movement education are identified:the motor program analogy, the neurobiological systems analogy, theinstinctive movement analogy, and the embodied exploration analogy.Three issues related to logical consistency and its relevance for movementeducation are raised. The first relates to tensions between theanalogies and educational policy. The second concerns differencesamong the four analogies. The third issue relates to the appropriatenessof specific analogies for dealing with certain movement contexts.In each case, strategies for improvement are considered. Thearticle concludes with a brief summary, along with reflections onissues that require further attention.

    How to End a Discussion: Consensus or Hegemony?2019Ingår i: Democracy & Education, ISSN 1085-3545, E-ISSN 2164-7992, Vol. 27, nr 2, s. 1-5Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    By taking the vantage point of agonistic pluralism, the aim is to enter into dialogue with Samuelsson’s theoretical development of consensus as an educational aim for classroom discussions. The response highlights three points of interest in the deliberative conception of consensus. The first point relates to the problem of exclusion, which Samuelsson clearly framed as something that concerns deliberative theory and agonistic theory. The second point is about the relation between conflict and consensus and the kind of conflict that is compatible with Samuelsson’s idea of consensus. The concluding part of this response is an exploration of how the agonistic concept of hegemony could function as an alternative aim for ending classroom discussions.

    What is complex in complex movement? A discourse analysis of conceptualizations of movement in the Swedish physical education curriculum2019Ingår i: European Physical Education Review, ISSN 1356-336X, E-ISSN 1741-2749, Vol. 25, nr 4, s. 1146-1160Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In 2011, the Swedish National Agency for Education introduced a new national curriculum. Thecurriculum contained a number of new terms. One in particular proved problematic for physicaleducators – complex movement. The confusion surrounding the term could be seen as somewhatunexpected since movement is and has been a central element of practically all physical education(PE) curricula. The specific aim of this paper is to identify how the discourse regarding complexmovement is assembled, and by doing so, provide insights into the meaning(s) of complexmovement within the context of PE policy in Sweden. Following Englund and Quennerstedt (2008),the study is framed within a Swedish curriculum theory tradition and six policy texts are examinedusing a discourse analytic methodology. The results suggest three different inferences of complexmovement discourse: advanced with a wide meaning; context-dependent and related to sports forolder pupils; and knowledge-dependent where different views about knowledge exist. From theseresults, three discussion points are raised related to: the diversity of possible meanings presentedin policy; the connection between knowledge and understanding; and the probability of differentaudiences reading the texts in different ways. The paper is concluded with a consideration of theconsequences of different inferences concerning complex movement and whether greater consensusis necessary.

    Understanding learners’ sense making of movement learning in physical education2019Ingår i: Curriculum Studies in Physical Education and Health, ISSN 2574-2981, Vol. 10, nr 2, s. 172-186Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    There is a substantial body of physical education scholarshipfocusing on movement learning. The question of how pupilsthemselves make sense of movement learning has however,largely escaped attention. Answers to such a question wouldseem to be highly germane if educators are to engage in pupilcenteredpedagogies. In light of this absence, the aim of thisinvestigation was to describe how movement learners madesense of their own movement development. Drawing ontheoretical tenets of Gilbert Ryle (2009. The concept of mind.New York, NY: Routledge) and Michael Polanyi (1969. Knowing andbeing. Essays by Michael Polanyi. Chicago, IL: University of ChicagoPress), three cases from an investigation in which movementlearning was occurring are presented. The investigation wasconducted during a physical education project week with pupilsfrom an upper secondary school. Data were produced usingobservations, informal interviews, semi-structured interviews, andresearch diaries as a group of pupils learned to juggle. The resultssuggest that: the aspects of moving to which learners attendchange as they learn; learners have a relatively limited capacity toverbally articulate what they learn, and; learners’ expectations ofideal ways of moving have considerable impact on how theycome to make sense of their own ways of moving. The practicalimplications of these points are discussed in the final section ofthe paper.

    Joy, fear and resignation: Investigating emotions in physical education using a symbolic interactionist approach2019Ingår i: Sport, Education and Society, ISSN 1357-3322, E-ISSN 1470-1243Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Emotional dimensions of physical education have garnered attention fromscholars in the last two decades. Many scholars claim that emotionssignificantly affect learning and that positive emotions such as joy andpleasure are necessary for continued participation in movementactivities beyond the classroom. Much of the existing literature,however, is based on the idea that emotions comprise internal mentalstates that are retrospectively oriented. In the current paper, we workwith alternative principles that can create new understandings of theaffective dimensions of PE and specifically, movement learning. We drawon symbolic interactionist principles, framing emotions as multimodalcommunicative resources that are performed in social contexts. Fromthis perspective, we demonstrate how emotions: (1) can be investigatedas part of the production of broader sequences of pedagogical actionand (2) relate to issues of knowledge, identity and authority. We presentobservational material generated with PE teacher education students asthey develop movement capability. We focus on three interactionalepisodes in which fear, joy and resignation are performed by studentsinteracting with either peers or an observing researcher. In each case,we demonstrate how emotions: affiliate or dis-affiliate the actor with themovement knowledge in focus, index an institutionally recognizableidentity and influence the subsequent actions of the participants in theinteractional sequence. The key thesis developed in the paper is that assymbolic resources, emotions have important consequences for actorswithin movement learning environments. The paper is concluded withreflections on the implications of the approach for practitioners alongwith a consideration of questions in need of further scientific attention.

    Resource Sharing in Real-Time Systems on Multiprocessors2012Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    In recent years multiprocessor architectures have become mainstream, and multi-core processors are found in products ranging from small portable cell phones to large computer servers. In parallel, research on real-time systems has mainly focused on traditional single-core processors. Hence, in order for real-time systems to fully leverage on the extra capacity offered by new multi-core processors, new design techniques, scheduling approaches, and real-time analysis methods have to be developed.

    In the multi-core and multiprocessor domain there are mainly two scheduling approaches, global and partitioned scheduling. Under global scheduling each task can execute on any processor at any time while under partitioned scheduling tasks are statically allocated to processors and migration of tasks among processors is not allowed. Besides simplicity and efficiency of partitioned scheduling protocols, existing scheduling and synchronization techniques developed for single-core processor platforms can more easily be extended to partitioned scheduling. This also simplifies migration of existing systems to multi-cores. An important issue related to partitioned scheduling is the distribution of tasks among the processors, which is a bin-packing problem.

    In this thesis we propose a blocking-aware partitioning heuristic algorithm to distribute tasks onto the processors of a multi-core architecture. The objective of the proposed algorithm is to decrease the blocking overhead of tasks, which reduces the total utilization and has the potential to reduce the number of required processors.

    In industrial embedded software systems, large and complex systems are usually divided into several components (applications) each of which is developed independently without knowledge of each other, and potentially in parallel. However, the applications may share mutually exclusive resources when they co-execute on a multi-core platform which introduce a challenge for the techniques needed to ensure predictability. In this thesis we have proposed a new synchronization protocol for handling mutually exclusive resources shared among real-time applications on a multi-core platform. The schedulability analysis of each application is performed in isolation and parallel and the requirements of each application with respect to the resources it may share are included in an interface. The protocol did not originally consider any priorities among the applications. We have proposed an additional version of the protocol which grants access to resources based on priorities assigned to the applications. We have also proposed an optimal priority assignment algorithm to assign unique priorities to the applications sharing resources. Our evaluations confirm that the protocol together with the priority assignment algorithm outperforms existing alternatives in most cases.

    In the proposed synchronization protocol each application is assumed to be allocated on one dedicated core. However, in this thesis we have further extended the synchronization protocol to be applicable for applications allocated on multiple dedicated cores of a multi-core platform. Furthermore, we have shown how to efficiently calculate the resource hold times of resources for applications. The resource hold time of a resource for an application is the maximum duration of time that the application may lock the resource whenever it requests the resource. Finally, the thesis discusses and proposes directions for future work.

    Partitioned Scheduling of Real-Time Tasks on Multi-core Platforms2010Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    In recent years multiprocessor architectures have become mainstream, and multi-core processors are found in products ranging from small portable cell phones to large computer servers. In parallel, research on real-time systems has mainly focused on traditional single-core processors. Hence, in order for real-time systems to fully leverage on the extra capacity offered by new multi-core processors, new design techniques, scheduling approaches, and real-time analysis methods have to be developed.

    In the multi-core and multiprocessor domain there are mainly two scheduling approaches, global and partitioned scheduling. Under global scheduling each task can execute on any processor at any time while under partitioned scheduling tasks are statically allocated to processors and migration of tasks among processors is not allowed. Besides simplicity and efficiency of partitioned scheduling protocols, existing scheduling and synchronization methods developed for single-core processor platforms can more easily be extended to partitioned scheduling. This also simplifies migration of existing systems to multi-cores. An important issue related to partitioned scheduling is distribution of tasks among processors which is a bin-packing problem.

    In this thesis we propose a partitioning framework for distributing tasks on the processors of multi-core platforms. Depending on the type of performance we desire to achieve, the framework may distribute a task set differently, e.g., in an application in which tasks process huge amounts of data the goal of the framework may be to decrease cache misses.Furthermore, we propose a blocking-aware partitioning heuristic algorithm to distribute tasks onto the processors of a multi-core architecture. The objective of the proposed algorithm is to decrease blocking overhead of tasks which reduces the total utilization and has the potential to reduce the number of required processors.Finally, we have implemented a tool to facilitate evaluation and comparison of different multiprocessor scheduling and synchronization approaches, as well as different partitioning heuristics. We have applied the tool in the evaluation of several partitioning heuristic algorithms, and the tool is flexible to which any new scheduling or synchronization protocol as well as any new partitioning heuristic can easily be added.

    #Gymlad: young boys learning processes and health-related social media2019Ingår i: Qualitative Research in Sport, Exercise and Health, ISSN 2159-676X, E-ISSN 2159-6778Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Recent systematic reviews identify that the factors mediating and/or moderating the relationship between social media and health outcomes are sparse. There have also been few attempts to analyse gender specific uses of social media. This paper investigated young boys health-related learning in relation to social media. Data were generated from class activities and interviews and from a large data set that included 1346 young people. The approach to the empirical data adopted was Practical Epistemology Analysis (PEA). The findings reveal two main purposes of young boys engagement with social media: (i) communicating with friends, and (ii) accessing health-related information. Irony and humour were central learning mechanisms used by young boys to participate within health-related social media, and in a way that enabled them to engage with, uphold, and handle health discourses associated with masculinity – such as being ripped – without fear of ‘literal’ peer ridicule and within a context of acceptable ‘banter’. There was evidence that young people were critical users and generators of social media, who were clearly thinking through what they see, do, and use online. Hence, this paper provides a fresh evidence-based perspective on the potentially positive role of social media as a health-related learning resource. PEA is illustrated as a new methodological approach for investigating learning in the context of social media. The evidence generated can be used to inform future evaluations of social media use, the design of educative support for young people, and guidance and training for key stakeholders.

    Magnetic Resonance Imaging of the Heart: Image quality, measurement accuracy and patient experience2016Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Background: Non-invasive diagnostic imaging of atherosclerotic coronary artery disease (CAD) is frequently carried out with cardiovascular magnetic resonance imaging (CMR) or myocardial perfusion single photon emission computed tomography (MPS). CMR is the gold standard for the evaluation of scar after myocardial infarction and MPS the clinical gold standard for ischemia. Magnetic Resonance Imaging (MRI) is at times difficult for patients and may induce anxiety while patient experience of MPS is largely unknown.

    Aims: To evaluate image quality in CMR with respect to the sequences employed, the influence of atrial fibrillation, myocardial perfusion and the impact of patient information. Further, to study patient experience in relation to MRI with the goal of improving the care of these patients.

    Method: Four study designs have been used. In paper I, experimental cross-over, paper (II) experimental controlled clinical trial, paper (III) psychometric crosssectional study and paper (IV) prospective intervention study. A total of 475 patients ≥ 18 years with primarily cardiac problems (I-IV) except for those referred for MRI of the spine (III) were included in the four studies.

    Result: In patients (n=20) with atrial fibrillation, a single shot steady state free precession (SS-SSFP) sequence showed significantly better image quality than the standard segmented inversion recovery fast gradient echo (IR-FGRE) sequence (I). In first-pass perfusion imaging the gradient echo-echo planar imaging sequence (GREEPI) (n=30) had lower signal-to-noise and contrast–to-noise ratios than the steady state free precession sequence (SSFP) (n=30) but displayed a higher correlation with the MPS results, evaluated both qualitatively and quantitatively (II). The MRIAnxiety Questionnaire (MRI-AQ) was validated on patients, referred for MRI of either the spine (n=193) or the heart (n=54). The final instrument had 15 items divided in two factors regarding Anxiety and Relaxation. The instrument was found to have satisfactory psychometric properties (III). Patients who prior CMR viewed an information video scored significantly (lower) better in the factor Relaxation, than those who received standard information. Patients who underwent MPS scored lower on both factors, Anxiety and Relaxation. The extra video information had no effect on CMR image quality (IV).

    Conclusion: Single shot imaging in atrial fibrillation produced images with less artefact than a segmented sequence. In first-pass perfusion imaging, the sequence GRE-EPI was superior to SSFP. A questionnaire depicting anxiety during MRI showed that video information prior to imaging helped patients relax but did not result in an improvement in image quality.

    Elektroniska marknadsplatser: IT-stöd för små och medelstora leverantörer2019Doktorsavhandling, monografi (Övrigt vetenskapligt)
    Abstract [sv]

    Den här avhandlingens ämne är elektroniska marknadsplatser och hur sådana bör utformas utifrån mindre leverantörers perspektiv. Med leverantörer avses här de säljande företag som använder marknadsplatser som mellanhand för att sälja varor och tjänster. I den situation som studerats används ofta denna kanal på begäran av kunden och dessutom via en marknadsplats vars utformning primärt är utformad utifrån kundens behov. Den kategori av marknadsplatser som har studerats har vidare inriktning mot inköp och försäljning mellan organisationer och företag.

    En central utgångspunkt och viktig förutsättning för studiens berättigande är uppfattningen om att forskningen kring den här kategorin av elektroniska marknadsplatser visat ett oproportionerlig litet intresse för just leverantörernas situation i allmänhet och de mindre aktörerna i synnerhet. Detta trots att ett reellt kunskapsbehov existerar såväl inomvetenskapligt som i praktikfältet. Det problem som ligger bakom praktikfältets kunskapsbehov har dessutom aktualiserats och accentuerats i Sverige under avhandlingsarbetes absoluta slutfas. Detta genom förändrad lagstiftning som innebär att alla leverantörer till offentlig sektor har krav på sig att kunna kommunicera elektroniskt.

    Den övergripande forskningsfråga som behandlas har formulerats som: ”Vilken utformning bör en elektronisk marknadsplats ha för att stödja mindre leverantörers ändamål?” och sedermera besvarats genom utveckling, presentation och tillämpning av en uppsättning utformningskriterier. Den övergripande forskningsstrategin har omfattat genomförande av en kvalitativ fallundersökning bestående av flera delstudier och praktikteori har utgjort ett centralt teoretiskt perspektiv. Undersökningens primära fall har varit den väletablerade skandinaviska marknadsplatsen Visma Proceedo och det praktiska genomförande har inneburit insamling och analys av data i form av intervjuer, dokument och demosystemtester.

    Kunskapsbidraget studien resulterat i består av fyra delar: en uppsättning utformningskriterier för elektroniska marknadsplatser, en kategorisering av mindre leverantörers ändamål, begreppsutveckling om s.k. marknadsplatspraktiker respektive ett antal praktikteoretiska utformningsprinciper. De två förstnämnda bidragen är riktade mot både praktikfältet och forskarsamhället med de två senare mer teoretiskt och inomvetenskapligt ämnade.

    Utformningskriterierna består av sju preskriptiva utsagor vilka är ämnade att kunna användas som riktningsvisare vid marknadsplatsutformning. Kriterierna utgör därmed det egentliga svaret på den övergripande forskningsfrågan. Studiens identifiering och kategorisering av de mindre leverantörernas ändamål visar att leverantörerna använder marknadsplatsen för att tillmötesgå befintliga kunders önskemål och krav. Vidare visar analysen två huvudkategorier vilka utgör centrala förutsättningar för de mindre leverantörernas aktivitet på den här typen av elektronisk marknadsplats: dels möjligheten till kontroll: att kunna granska och påverka sin egen information och dels behovet av matchning: överensstämmelse mellan marknadsplatsaktiviteten och den övriga (egna) verksamheten.

    I syfte att betrakta, analysera och förstå det studerade fenomenet presenterar avhandlingen också de två praktikteoretiska begreppen marknadsplatspraktik respektive försäljningspraktik. Intressenter för detta bidrag finns primärt bland forskare med intresse praktikteori och interorganisatoriska företeelser som elektroniska marknadsplatser.

    På vägen mot de tillämpningsspecifika utformningskriterierna har avhandlingsarbetet emellertid också inneburit teoriutveckling på ett betydligt mer generiskt plan. Resultatet är att en till karaktären deskriptiv praktikteoretisk modell har utökats med en uppsättning designprinciper. Principerna är resultat av en teoretisk syntes av informationssystemteori, sociotekniska designprinciper och praktikteori. Då principerna och tillämpningen av dem presenteras åtskilt från varandra är det möjligt för andra att tillämpa, testa och vidareutveckla dem helt bortom undersökningens fall och studieområde.

    Geographies of Place Branding: Researching through small and medium sized cities2015Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Place branding is commonly conceptualized with a focus on big cities, such as London, New York and Singapore, building from concepts and models from mainstream branding theory. In contrast to such conceptualizations, this thesis focuses on place branding in small and medium-sized cities. The present thesis aims to study place branding from a geographical perspective. It starts with debates theoretical and empirical understandings of place branding; what it is and how it is affecting the places where it is introduced. The thesis develops and argues for a perspective of territoriality and relationality to place branding discussing concepts, methods and empirical approaches to carry out place branding research using geographical perspectives. Empirically, this thesis focuses on in-depth studies of place branding in small and medium-sized cities in Sweden. By analyzing the development of place branding over the course of time, nuances and aspects of both territorial and relational origin emerge, situating place branding practices within a wider spatial contextualization. Four individual papers are presented, which taken together contribute to the aim of the thesis. Paper 1 introduces the place branding research field in geography and how it has developed; Paper 2 investigates the phenomena of flagship buildings located in small cities and towns; Paper 3 discusses the relationship between policy tourism and place branding; and Paper 4 analyzes how local environmental policies are affected by green place branding. The thesis demonstrates the complex and continuously interchangeable spatial structures and place contexts that create and re-produce the geographies of place branding. Here, research models and methodological examples are presented to illustrate how place branding can be studied from a geographical perspective and thus improve theoretical understandings of place branding.

    E-Government and Value Creation in the Context of a Least Developed Country: A perspective on public value and information infrastructure2019Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    This thesis is in the field of information systems (IS), more specifically about IS impact. This thesis uses literature review and interpretive case study methods to investigate the phenomenon of value creation through e-government.

    The research was carried out from 2014 to 2019. Data was collected through interviews, participant observations, and document review. The main research question is "How do we create value through e-government in the context of an LDC?” It embodies the sub-questions: what is the value of e-government? And how do we attain such value?

    This thesis comprises four studies.

    The thesis found that value creation of e-government is a process of understanding: the value that e-government creates; the context in which egovernment resides because a process involves a context; and strategic actions to create that value within the context surrounds e-government.

    From the findings, this thesis argues that the value of public affairs including e-government refers to public value. The latter would mean citizens' collective expectations about public policies and services. Also, the findings reveal research needs about the public value of e-government in the LDCs in Sub-Saharan Africa and on methods of measuring and creating the public value of e-government.

    As original contribution, this thesis suggests a framework of six overarching and overlapping areas of e-government for the public value. The anticipation-reality gaps and their inter-relationships are identified, and five inter-related critical success factors are suggested. Also, the information infrastructure (II) framework, particularly, the notion of the cultivation of the installed-base is suggested as a promising avenue in the management of the public value creation in general, and in an LDC in particular.

    Abstract [en]

    This study organizes existing research on the public value of e-government in order to investigate the current state and what value e-government is supposed to yield. The two questions that guided the research were: (1) What is the current state of research on the public value of e-government? And (2) What value is e-government supposed to yield? Six, sometimes overlapping, values were found: Improved public services; improved administrative efficiency; Open Government (OG) capabilities; improved ethical behaviour and professionalism; improved trust and confidence in government; and improved social value and well-being. These six public value dimensions were thereafter generalized into three overarching, and also overlapping, public value dimensions of Improved Public Services, Improved Administration, and Improved Social Value. The improved public services dimension influences other dimensions. Hence, this literature study theorizes a descriptive and multidimensional framework that can improve our understanding of the public value of e-government from different viewpoints, and the overlap between them in actual e-government designs and implementations. Regarding the current state of research on the public value this study found a lack of research on the public value of e-government, especially, in the context of developing countries – and more importantly – a total absence of this kind of research in the Least Developed Countries (LDCs). There is also a lack of comparative studies at national, regional, and project level; and a lack of research on the generative perspective.

    Abstract [en]

    E‑government is currently high on the agenda in many developing countries (DCs). While e‑government is well‑established in many developed countries it is new to least developed countries. Countries that start implementing e‑government today can benefit from easy import of modern technologies, but adaptation to local conditions and the organizational change that is required cannot be imported, but must be developed at home. By using examples of an ongoing initiative by the Government of Rwanda to digitalize all G2C and G2B into a single window platform, the current study investigated the important challenges in the implementation of e‑government in Rwanda. An interpretive case study was followed. Data was collected through interviews and participatory observations during August to December 2015. Data analysis was inductive, the analysis method was content analysis, and the coding followed open‑coding. NVivo software has been used to handle data and facilitate the analysis. The study found six overarching categories of aspects that challenge a successful implementation of e‑government in Rwanda. They include information infrastructure for e‑government, social inclusion, governance, management, trust in the new system, and languages. However, challenges to e‑government implementation should not be taken as of the same extent, neither their degree of mitigation. Rather, they influence and are influenced by various contextual factors which include political support, nature of the e‑government project, implementation strategies, human and socio‑economic development, existing information infrastructure, and operational capabilities. Having said this, we also argue that countries should learn from one another of their experiences, success stories, and mistakes. Despite a number of associated challenges, the adopted public‑private partnership (PPP) approach to e‑Government implementation in Rwanda might indeed seem as a suitable catalyst for e‑government success in the country.

    Singing, sharing, soothing: Family-centred music therapy during painful procedures in neonatal care2019Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    To sing is to communicate. The soothing, comforting and emotional regulating properties of a lullaby are well-known cross-culturally and historically. This doctoral thesis addresses neonatal pain management from a novel and groundbreaking perspective, studying the efficacy of live music therapy on infants’ pain responses during venepuncture. New research is needed to advance the non-pharmacological interventions in neonatal pain care, and neonatal music therapy (NICU MT) offers active methods to involve the parents in pain management. The doctoral thesis includes two empirical and two theoretical articles. In paper I, preterm and term infants (n=38) were subjected to venepuncture with and without live lullaby singing, in a randomised order with a crossover design. Parent-preferred lullabies were performed live by a music therapy student and standard care was provided for all infants. The results did not show any significant pain-alleviating effects, however, the live singing was not stressful for the infants.

    In paper II, the microanalysis disclosed that live lullaby singing is a communicative reciprocal intervention that also applies to premature infants during painful procedures. Live lullaby singing is a tool suitable as a means to optimise the homeostatic mechanisms. The results from the theoretical papers III and IV are further developed and synthesised in the thesis into a theoretical strategy; The Nordic NICU MT pain management strategy, featuring the parents and their singing voices as mediators for pain relief. The role of the music therapist in neonatal pain management is as a facilitator and an educator for the parents. Coaching parents to better meet their infant’s attachment needs during a painful procedure may lead to more efficacious interventions. The biopsychosocial parental infant-directed singing is presumably an applicable parent-driven non-pharmacological intervention, which promotes pain relief and attachment formation during painful procedures. Neonatal music therapy is still in its infancy in the Nordic countries, but the societal and healthcare contexts afford important prerequisites to further develop NICU MT as a truly family-centred approach. This doctoral thesis will hopefully contribute to the important interdisciplinary endeavour worldwide of involving and integrating parents in neonatal pain management.

    Abstract [en]

    This clinical trial tested the pain relieving effect of live lullaby singing on behavioral and physiological pain responses during venepuncture in 38 preterm and full term neonates. Acute and repeated pain, as well as the use of analgesic drugs, may have long-term negative impact on infants’ development and future behaviour. This emphasizes the need for complementary approaches to pain management such as music therapy.

    Parent-preferred lullabies were performed live and standard care was provided for all neonates. Behavioral responses with regard to pain were assessed with Premature Infant Pain Profile-Revised (PIPP-R) and Behavioral Indicators of Infant Pain (BIIP). Heart rate, respiratory rate and oxygen saturation were measured each tenth second.

    Although the live lullaby singing did not show a statistically significant effect on the infants’ pain score, there was a significantly calmer breathing pattern in the lullaby intervention versus the control condition in the pre-needle stage, showing a non-significant trend towards higher oxygen saturation levels and calmer heart rate in the lullaby intervention versus the control condition in the pre-needle stage. There were non-significant indications of fewer and shorter skin punctures with lullaby singing. More research is needed to explore such positive trends in the data.

    Abstract [en]

    During the most vulnerable period in a child’s life, preterm and sick infants are exposed to a high number of painful procedures, sometimes without the comfort and affection of their parents. Since repeated pain and frequent use of analgesic drugs may have consequences for the neurological and behaviour-oriented development of the infant, it is vital to identify effective non-pharmacological interventions with regard to procedural pain. This paper reviews the use of live lullaby singing as an adjuvant to the control of premature infant pain. The objectives of this case study were to analyse the live lullaby singing for two premature infants during venipuncture in comparison to standard care only, and the infants’ physiological and affective responses emerging before, during and after this procedure. The empirical data stem from a quantitative clinical study. From this larger study, two premature infants were selected. Through microanalysis, with in-depth analysis of video footage, and pain assessment with Behavioral Indicators of Infant Pain (BIIP), painful standard care procedures with and without live lullaby singing, were analysed. The results show that live lullaby singing with premature infants is a communicative interaction which may optimize the homeostatic mechanisms of the infant during painful procedures. This case study shows the importance of predictability of the affective support, right from the start of the live singing intervention. It is important in a painful context that vocal interactions provide regular and comforting intensity, shape and temporal structures.

    Abstract [en]

    Infant-directed singing is a medium for parents and infants to communicate in a mutual relationship. Parental infant-directed singing is a multisensory, biopsychosocial communication that applies to ill and vulnerable hospitalised infants. The primary musical features of infant-directed singing are ideal for emotional coordination and sharing between parent and infant without the risk of over-stimulation. In this article, we suggest that parental infant-directed singing is regarded as a nonpharmacological emotion regulation intervention, which may modify the painful experience for both the infant and the parent before, during and after painful procedures in the neonatal intensive care context. Parents have the biopsychosocial resources to alleviate their infant’s pain through infant-directed singing, if they are empowered to do so and coached in this process. A music therapist specialised in neonatal music therapy methods can mentor parents in how to use entrained and attuned live lullaby singing in connection to painful procedures. Pain and the vast amount of painful procedures early in infancy, combined with early parent–infant separation and lack of parental participation in the care of the infant during neonatal intensive care, place arduous strain on the new family’s attachment process and on the infant’s and parents’ mental health, both from a short and long-term perspective. Therefore, we argue with biopsychosocial rationales, that live parental infant-directed singing should be promoted in neonatal pain care worldwide. Consequently, parents should be welcomed round the clock and invited as prescribed pain management for their infant.

    Abstract [en]

    Since the 1990s, the concept of family-centred care, where the family and healthcare staff share responsibility for the infant’s hospital care, has been part of an ongoing paradigm shift in neonatal care globally. The public health care system with family-friendly parental leave policies might be one of the reasons that the Nordic countries today are at the forefront of welcoming and including parents and partners in the care of their infant round the clock. When implementing neonatal music therapy (NICU MT) in the context of Nordic health care, music therapy models of practice as well as research ought to be defined and shaped by the family-centred care model, which today is considered best practice. The Nordic context also offers favourable conditions for further developing NICU MT approaches in line with family-centred care. NICU MT was first developed in the USA in the 1980s and the interventions were infantfocused, emphasising the infant’s physical and medical needs, which was the existing care focus in neonatal care at that time. Neonatal music therapy and research in the Nordic countries is still in its infancy. Systematic implementation work was first initiated in Karlstad, Sweden in 2010 and in Akershus and Oslo, Norway in 2017. 

    This essay provides the international music therapy field as well as other professionals in paediatric and neonatal health care an insight into the evolving Nordic approach of NICU MT. The conclusion of this essay is that the familycentred care approach in the Nordic NICUs, combined with the progressive family politics in the Nordic countries with generous parental leave schemes and gender equality in childcare, afford important prerequisites to further develop NICU MT as a truly family-centred approach.

    Real-time kinematical optimal trajectory planning for haptic feedback manipulators2019Ingår i: Simulation, ISSN 0037-5497, Vol. 95, nr 7, s. 621-635Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    To obtain real-time haptic interactions in virtual cockpit systems (VCSs), a real-time trajectory planning method based on kinematical optimization for haptic feedback manipulators (HFMs) is presented in this paper. Firstly, the control panel area is extracted in the workspace of the HFM, in which the interacting point is located. Then a feasible interacting configuration is calculated as the objective configuration of the trajectory encoded by a parametric representation. The trajectory planning problem is formulated as a non-linear optimization problem based on kinematics, which is solved in real-time by finding a good initial solution with machine learning methods. Simulations show that trajectories with a compromise between safety and rapidity can be calculated in real-time by this method, which provides a basis for haptic interaction in VCSs.

    Anxiety during magnetic resonance imaging of the spine in relation to scanner design and size2019Ingår i: Radiography, ISSN 1078-8174, E-ISSN 1532-2831Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Introduction: Magnetic resonance imaging in closed-bore scanners sometimes provokes anxiety but closed-bore designs have gradually become wider and shorter. Open scanners may be easier to tolerate. The aim was to compare patient anxiety during MRI between bore diameters of 60 cm and 70 cm, and to determine the current level of patient anxiety and experience in open scanners in a clinical setrting.

    Methods: Consecutive patients referred for examination of the spine in 60 cm and 70 cm bores and one open scanner participated. Four established/validated questionnaires, answered before, directly after (N = 155) and one week after (N = 109) the MRI-examination were used, measuring anxiety, fear and depression.

    Results: No difference was found in the patient scores of anxiety between the 60 cm and the 70 cm scanners on the examination day. At follow-up, patients in the 70 cm bore rated their examination experience better (p < 0.025), compared to patients in the 60 cm bore. Patients in the open scanner rated higher levels of anxiety (p < 0.001) before, directly after and one week after the examination, compared to the closed bore scanners.

    Conclusion: Scanners with a 70 cm diameter bore seem more tolerable than those with a 60 cm bore. Patients referred to the open scanner had on average a higher tendency to express anxiety. Still, patient anxiety in MRI is challenging and further research required.

    Implications for practice: Patients prefer to be examined in 70 cm bore scanners compared with 60 cm. If open scanners aren't available extended support may be necessary for the most anxious patients.

    Lipidomics is a rapidly-growing field which focuses on global characterization of lipids at molecular and systems levels. As small changes in the concentrations of lipids may have important physiological consequences, much attention in the field has recently been paid to more accurate quantitation and identification of lipids. Community-wide efforts have been initiated, aiming to develop best practices for lipidomic analyses and reporting of lipidomic data. Nevertheless, current approaches for comprehensive analysis of lipidomes have some inherent challenges and limitations. Additionally, there is, currently, limited knowledge concerning the impacts of various external and internal exposures on lipid levels. In this review, we discuss the recent progress in lipidomics analysis, with a primary focus on analytical approaches, as well as on the different sources of variation in quantifying lipid levels, both technical and biological.

    Targeted Clinical Metabolite Profiling Platform for the Stratification of Diabetic Patients2019Ingår i: Metabolites, ISSN 2218-1989, E-ISSN 2218-1989, Vol. 9, nr 9, artikel-id E184Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Several small molecule biomarkers have been reported in the literature for prediction and diagnosis of (pre)diabetes, its co-morbidities, and complications. Here, we report the development and validation of a novel, quantitative method for the determination of a selected panel of 34 metabolite biomarkers from human plasma. We selected a panel of metabolites indicative of various clinically-relevant pathogenic stages of diabetes. We combined these candidate biomarkers into a single ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method and optimized it, prioritizing simplicity of sample preparation and time needed for analysis, enabling high-throughput analysis in clinical laboratory settings. We validated the method in terms of limits of detection (LOD) and quantitation (LOQ), linearity (R2), and intra- and inter-day repeatability of each metabolite. The method's performance was demonstrated in the analysis of selected samples from a diabetes cohort study. Metabolite levels were associated with clinical measurements and kidney complications in type 1 diabetes (T1D) patients. Specifically, both amino acids and amino acid-related analytes, as well as specific bile acids, were associated with macro-albuminuria. Additionally, specific bile acids were associated with glycemic control, anti-hypertensive medication, statin medication, and clinical lipid measurements. The developed analytical method is suitable for robust determination of selected plasma metabolites in the diabetes clinic.

    Responsibilization: The case of road safety governance2019Ingår i: Regulation and Governance, ISSN 1748-5983, E-ISSN 1748-5991Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Governments are increasingly turning to new modes of governance to induce nonstate actors to voluntarily take responsibility for societal problems. Using the concept of responsibilization as a theoretical lens, this article analyzes changes in road safety governance in Sweden. How, why, and to whom has the responsibility for road safety been attributed in Swedish policymaking, and how have state authorities engaged in processes of responsibilization during its implementation? The results show a shift in attribution of responsibility from individual road users to a broad set of so-called system designers, based on moral, causal, and preventive rationales. Responsibilization both occurs within the state apparatus and is imposed by state authorities on nonstate actors using soft governance measures. Responsibilization provides a fruitful theoretical lens for governance studies by identifying shifts in responsibility (including deresponsibilization), explicating normative/ethical underpinnings of new governance modes, and helping to open the “black box” of the state.

    Building Institutional Trust Through Service Experiences: Private Versus Public Provision Matter2019Ingår i: Journal of public administration research and theory, ISSN 1053-1858, E-ISSN 1477-9803Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Welfare service experiences are known to shape citizens' trust in public institutions and their sup-port of the welfare state. But, there is poor understanding of how this relationship is shaped in systems of mixed provision, that is, welfare states that use public in-house as well as contracted private providers for publically funded services. Drawing on the notion of system trust this article provides a theoretical account of how mixed-provision welfare systems condition the relationship between service experience and trust, affecting the legitimacy of the state. Utilizing a random-ized vignette experiment with participants in a general citizen survey in Sweden, we investigate whether it matters for the formation of institutional trust if the welfare service is provided by a public or third-party private provider. The main result show that the spillover of trust from positive service experiences with the provider to trust in public institutions is higher in cases of public ser-vice provision. Thus, the possibility of using welfare services to build trust in the welfare system seems to be greater when public provision is used.

    Allogenic Faecal Microbiota Transfer Induces Immune-Related Gene Sets in the Colon Mucosa of Patients with Irritable Bowel Syndrome2019Ingår i: Biomolecules, E-ISSN 2218-273X, Vol. 9, nr 10, artikel-id 586Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Faecal microbiota transfer (FMT) consists of the introduction of new microbial communities into the intestine of a patient, with the aim of restoring a disturbed gut microbiota. Even though it is used as a potential treatment for various diseases, it is unknown how the host mucosa responds to FMT. This study aims to investigate the colonic mucosa gene expression response to allogenic (from a donor) or autologous (own) FMT in patients with irritable bowel syndrome (IBS). In a recently conducted randomised, double-blinded, controlled clinical study, 17 IBS patients were treated with FMT by colonoscopy. RNA was isolated from colonic biopsies collected by sigmoidoscopy at baseline, as well as two weeks and eight weeks after FMT. In patients treated with allogenic FMT, predominantly immune response-related gene sets were induced, with the strongest response two weeks after the FMT. In patients treated with autologous FMT, predominantly metabolism-related gene sets were affected. Furthermore, several microbiota genera showed correlations with immune-related gene sets, with different correlations found after allogenic compared to autologous FMT. This study shows that the microbe–host response is influenced by FMT on the mucosal gene expression level, and that there are clear differences in response to allogenic compared to autologous FMT.

    Att lära genom improvisation: en didaktisk studie i grundskolans musikundervisning2019Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    In the growing field of research on improvisation, it is argued that improvisation should be at the core of music education, and in many curricula improvisation is in fact emphasized. However, in general music education, as well as research, improvisation is still overlooked. There seem to be a discursive gap between ‘everyday’ and artistic perceptions of improvisation and the way it is perceived didactically. Improvisation is also a creative music activity form and as such it cannot have prescribed outcomes. Yet, the current goal- and result driven schooling system focuses on achieving prescribed knowledge requirements. This situation constitutes an educational paradox. Through a systematic literature review, interviews with teachers and a practice-based study, this thesis explores the conditions and the role of improvisation in general music education. The theoretical perspective is based on Dewey’s pragmatist philosophy, and his concepts of aesthetic experience and transaction. Results show that improvisation is conceptualised in a continuum between structure and freedom and that teachers’ didactical approaches to improvisation can be oriented towards the process, the subject or Bildung. However, teachers’ perceptions of improvisation as related to jazz and blues sometimes present a hindrance. Combining a practical epistemology analysis with Dewey´s concept of the esthetic event (Dewey´s spelling) provides new insights into the process and content of aesthetic meaning-making. Improvising pupils who have an aesthetic experience can develop expressivity, agency and responsivity (EAR) as well as aspects of embodied, cognitive and ethical knowledge. The transactional perspective and 5 concepts developed here provide new insights in how to understand improvisation in education: as ethically co-creative action, co-learning action, explorative action, a space for imagination and emotional engagement and finally a room for subjectification. This implies a negotiated role for the teacher as co-player. A practical aesthetic analysis (PESA) is suggested which emphasises the specific nature of the aesthetic experience.

    Abstract [en]

    The overall purpose of this article is to provide a convenient summary of empirical research on improvisation in general music education and thereby provide guidance to researchers and practitioners, using a systematic, narrative-review approach. By analysing 20 music education research articles, published from 2000–2015 in peer-reviewed journals,we firstly provide an overview of the key features and knowledge of existing research. Secondly we identify how improvisation has been characterized, conceptually before, thirdly, describing the implications of the literature for improvisation in practice. Our article reveals that improvisation tends to be an overlooked activity both in music education contexts and in music education research. Broadly speaking, music education research tends to characterise improvisation within two conceptual frameworks, which have different implications for implementation; ‘structured’, teacher-directed improvisation and ‘free’, child-directed improvisation. We conclude by arguing that music educational research on improvisation is an underdeveloped field and outline a number of questions to be addressed in future research.

    Abstract [en]

    In this chapter I argue that specific valuable educational qualities can be developed through free group improvisation in general music education. My claims are operationalised through a set of research questions to investigate students’ actions, and characteristics as well as implications of these actions in improvisation events. John Dewey’s theory of aesthetic experience, and more specifically an experience, is employed as analytical lens in analysis of children’s improvisations. I argue that an experience in improvisation occurs in and through a reciprocal interaction with the environment which means that when children improvise, they change due to their musical experiences but they also in turn change their musical environment. Crucially, I argue that having an experience in free group improvisation can cultivate Expressiveness, Agency and Responsiveness.

    Abstract [en]

    Improvisation in general music education is still a somewhat underdeveloped practice. Moreover, attempts to justify its place in the curriculum have often focused solely on its (measurable) outcomes. In this article, we claim that a deeper understanding of students' meaning-making processes in experiences of improvisation is necessary in order to develop improvisation practice and research. The purpose of this article is to offer a music education perspective on improvisation based on John Dewey's transactional perspective on aesthetic experience and meaning-making. Related to this, we suggest and illustrate a Practical Epistemology Analysis (PEA) as a way of analysing meaning-making in music improvisation within general music education. The method of analysis is illustrated by vignettes from video analyses of music lessons in two Swedish schools with pupils aged 9-10 and their free improvisations. The vignettes show how PEA enables analyses of situated meaning-making in the progress of the pupils' improvisation activities. Further, the transactional perspective makes educational values of improvisation visible, such as musical and personal agency, and elucidates cognitive, embodied and ethical aspects of musical meaning-making.

    Complexity in the 'Extended' Business Network: A Study of Business, Social, and Political Relationships in Smart City Solutions2018Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    In this thesis an 'extended' business network is investigated. The ‘extended’ view refers to the inclusion of socio-political actors in the firm’s business network. Building on a business network perspective, the thesis’ purpose is to understand how interactions between business, social, and political actors influence the development of smart city solutions. Based on the findings from the four articles included in the thesis, a complexity lens for further understanding of interaction with socio-political actors is presented. It argues that reaching success in the relationship entails finding a balance between economic and social needs.

    Through the analysis of two smart city projects developed in Brazil, this study investigates the influence of socio-political actors on firms’ cooperative and competitive behavior as well as their decisions relating to resource allocation. The findings illustrate that decisions to cooperate or compete are associated with centrality. The firm’s willingness to be a central actor, i.e., a project leader, places traditional buyer-supplier partners in competition. In addition to this, resource allocation is closely linked to customization. In cities demanding a high level of customization of the smart city solution, companies will be encouraged to allocate resources to exploitation, while in cities requiring a low level of customization, exploration will be chosen instead. But knowledge about how to allocate resources is closely linked to the centrality issue, since a central actor may enjoy better access to a large pool of resources and information. Consequently, the final outcome in relational terms can lead to win-lose rather than a win-win situation if rivalry for centrality between business partners intensifies over time.

    The study of such complex interaction contributes to the industrial marketing and business network literature by providing a practical perspective and showing how socio-political actors can be a source of competitive advantages for companies. In addition, this thesis suggests that managers need to cope with the complexity inherent in such type of relationships, primarily due the fact that interaction with socio-political actors has important competitive implications for firms. Ultimately, the thesis offers a framework for investigating complexity in actors’ interactions and resource heterogeneity that complements our understanding of intraorganizational relationships, opening opportunities for a new perspective and better comprehension of the influence of socio-political actors in firms’ business networks.

    Factors influencing savings from electronic auctions2014Ingår i: Central European Review of Economic Issuer (CEREI), ISSN 1212-3951, Vol. 17, s. 209-216Artikel i tidskrift (Övrigt vetenskapligt)
    Abstract [en]

    The ratio of public procurement undertaken through reverse electronic auctions is increasing rapidly. Czech and Slovak municipalities use this tool to save public funds through fostering direct competition between suppliers and to increase transparency. The main aim of this paper is to analyse the savings achieved through e-auctions and the factors influencing these. Five variables are tested to establish whether they influence the savings: num-ber of participants (potential suppliers) in the e-auction, total value of the e-auction, size and country of origin of the municipality, and category of the procured product or service. Several methods are used to test independence. All of these factors except the country of origin influence the savings gained, which is in accordance with the findings of existing research.
