  • Value Network Transformation Digital Service Innovation in the Vehicle Industry
  • 2016
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • Advancement in digital technology is rapidly changing the contemporary landscape of business and associated networks for manufacturing firms. Many traditional physical products are now being embedded with digital components, providing them digital capability to become digitized products. The digitization of physical products has become an important driver for digital service innovation within manufacturing industries. Such digital service innovation transforms value networks of manufacturing firms in various industries. While digitization of products and digital service innovation can be observed in many manufacturing industries, this thesis focuses on the transformation of value networks within the vehicle industry.This thesis is a collection of papers and a cover paper. The thesis reports from a collaborative project in the vehicle industry. The project explored new digital services for vehicles based on remote diagnostics technology. The exploration and conceptualization of digital services is investigated in a collaborative manner with participants from the vehicle industry. The results reflect that there is a paradigm shift for manufacturing firms digitizing their products, and stretching the business scope from product to solution oriented business.This thesis contributes to the existing literature on digital innovation with insights on the transformation of value networks in the vehicle industry. The research question addressed in this thesis is: How are value networks of manufacturing firms transformed by digital service innovation? To answer the question, this thesis conceptualizes how the value creating pattern of digitized products transforms value networks of manufacturing firms. A model is presented that reflects how the symbiotic value relationship between the digitized product and digital services transforms the roles, relationships and exchanges in the value networks of manufacturing firms. The model can serve as an analytical tool to further advance the knowledge on business aspects in digital innovation. This thesis contributes to practice by providing an understanding of how manufacturing firms can leverage value of digitized products and digital services in value networks.

  • Prayer in Peasant Communities Ideals and Practices of Prayer in the Late Medieval Ecclesiastical Province of Uppsala, Sweden
  • 2010
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • The aim of this study has been to identify, explain and delineate praying among peasant communities in the ecclesiastical province of Uppsala, Sweden. Four aspects have been examined through the perspectives of ideals and practices, namely the standards of prayer, devotional prayer, prayer in times of need and prayer cultures. The standards of prayer considered the physical and mental behaviour of the praying peasant woman or man. The most ordinary way to act during prayer was to stand with hands together, palm against palm, and to pray in the vernacular often using mental themes to enhance the devotion. Devotional prayers were foremost the three ‘standard’ prayers Paternoster, Hail Mary and Apostolic Creed, and could be used separately or combined. Prayer in times of need was possibly considered a matter of praying to saints, something that cannot be proven to have been either practiced or recommended on other, ordinary occasions where God and the Virgin Mary were considered the proper recipients of prayer. A few authentic prayers exist that were possibly said by peasant women and men in connection with miracles and these show the ability to construct elaborate prayers and to propose businesslike agreements with saints. These three prayers were required knowledge for a peasant woman or man and were put to the test in order to become a godparent, and were therefore made available in the vernacular by the parish priests. Ways to maintain the prayer cultures were through mnemonic techniques, and indulgences stipulating and confirming prayers used or to be used in connection with certain churches, days and places within the churches. Name saints could also be used, since the person and the name saint were considered to have a special bond. Prayer could also be used as protection for the living; since a prayer was considered to generate either merits or favours from a celestial patron to his or her client. The prayer life of those belonging to peasant communities was both elaborate and full of nuances.

  • Entreprenörer som redovisare : bokslutsprocessen i Gasellföretag
  • 2008
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • Entrepreneurs seem to be highly valuable for the firms in which they are involved. However, the knowledge of the role of accounting in a context of entrepreneurship is limited. In fact, some literature on entrepreneurship indicates that the role of accounting is only about the past and therefore not of interest for entrepreneurs in the entrepreneurial process.This dissertation reports the results of two empirical studies. The first study is a qualitative pilot study of five entrepreneurs in fast growing firms and their participation in the year-end procedure. The respondents were presented the adjustments in the final step of the recording process and the annual report in order to assess their participation and to focus on how the entrepreneurs as producers of accounting reflect and act in relation to other actors and to the process of reporting. The pilot study found that the entrepreneurs were certainly involved in use and produce of certain accounting in the year-end procedures. The second study is based on the result from the pilot study and on agency theory the study aimed to describe and explain how and why entrepreneurs in successful fast growing firms, i.e. Gazelle firms, compared with a control group of managers in not growing firms, are participating in the year-end procedures. Also, the study aimed to analyse differences between entrepreneurs´ participation and other managers´ participation in this process. The study focused on the activities in the year-end procedures concerned with the values of R&D, stock and work-in-progress and accounts receivables. In order to find entrepreneurs the survey was sent to a sample of 257 managers of Gazelle firms and to a sample of 227 managers in not growing firms. Also, the annual report from the firms where the respondents where involved were collected. This data was also included in the study. The responding rate was 50% from both groups. The most notable finding is, in contradiction to literature on entrepreneurship, that entrepreneurs in Gazelle firms use and produce formal financial accounting information. Entrepreneurs in Gazelle firms spend more time and they are also involved in discussions with more actors compared with managers in not growing firms. Further, the results indicate that entrepreneurs in Gazelle firms will participate to a larger extent when the profitability in the firm decreases compared to managers in not growing firms. Finally, the dissertation gives insight in the role of formal financial accounting in the context of entrepreneurship, a research area we know little about.

  • Biomechanical studies of finger extension function. Analysis with a new force measuring device and ultrasound examination in rheumatoid arthritis and healhty muscles
  • 2008
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • Aims: The overall aim of this thesis was to further our understanding of extensor muscles and their role for hand function.The aims of the studies were: To develop and evaluate a new device for finger extensor force measurements. To evaluate ultrasound as a tool for assessment of muscle architecture. To determine the correlation between extensor muscle force and hand function. To evaluate the degree of impaired finger extensor force in rheumatoid arthritis (RA) and the correlation to impaired... mer hand function. To analyse the effect of hand exercise in RA patients and healthy subjects with ultrasound and finger extension force measurements.Method: A new finger extension force measuring device was developed and an ultrasound based method was used to be able to objectively measure the finger extension force and analyze the static and dynamic extensor muscle architectures. Measurements were made of healthy volunteers (n=127) and RA patients (n=77) during uninfluenced and experimental conditions. A hand exercise program was performed and evaluated with hand force measurements, hand function test, patient relevant questionnaires (DASH and SF-36) and ultrasound measurements.Results: The new finger extension force measurement device was developed and then validated with measurements of accuracy as well as test-retest reliability. The coefficient of variation was 1.8 % of the applied load, and the test-retest reliability showed a coefficient of variation no more than 7.1% for healthy subjects. Ultrasound examination on m. extensor digitorum communis (EDC) showed significant differences between healthy men and healthy women as well as between healthy women and RA patients. The extension and flexion force improved in both groups after six weeks of hand exercise (p<0.01). Hand function improved in both groups (p<0.01). The RA group showed improvement in the results of the DASH questionnaire (p<0.05). The cross-sectional area of the EDC increased significantly in both groups.Conclusions: A new finger extension force measuring device has been developed which provides objective and reliable data on the extension force capacity of normal and dysfunctional hands and is sufficiently sensitive to evaluate the effects of hand exercise. US provide useful information about muscle architecture. A significant improvement of hand strength and hand function in RA patients was seen after six weeks of hand training, the improvement was even more pronounced after 12 weeks. Hand exercise is thus an effective intervention for RA patients, providing better strength and function.

  • Service Logic in Digitalized Product Platforms A Study of Digital Service Innovation in the Vehicle Industry
  • 2015
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • The digitalization of products has become an important driver for service innovation in manufacturing firms. The embedding of digital technology in previously non-digital products creates digitalized product platforms that enable digital service innovation. Digital service innovation offers new business opportunities for manufacturing industries, as well as challenges established premises for value creation.  While digital service innovation can be found in many manufacturing industries, this thesis studies service logic in digitalized product platforms in the vehicle industry.Existing Information Systems (IS) literature presents challenges in digital service innovation relating to value, architecture, and generativity. The design of the architecture of digitalized product platforms requires the identification and combination of digital and non-digital assets. Understanding the architectural aspects is useful in digital service innovation. Moreover, with growing instances of generative digital technologies, it is challenging to develop strategies to leverage generativity for service design in digitalized product platforms. While digital technologies are embedded in products, the role of technology-embeddedness in value creation of digital services is relatively unexplored. Drawing on these challenges, this thesis describes and conceptualizes the underlying premises brought by the architecture and generativity to the value creation of services in digitalized product platforms. The research question addressed in this thesis is: What are the underlying premises for services in digitalized product platforms?To address the question, an interpretive qualitative research approach was adopted in a collaborative research project concerning services enabled by digitalization of vehicles. Drawing on digital innovation and service literature, this thesis presents a theoretical perspective on the role of the architecture and generativity of digitalized product platforms for value creation of digital services. This perspective is conceptualized as underlying premises for this specific class of services. The premises frame the service logic in digitalized product platforms and provide a ground for understanding services in digitalized product platforms in relation to value dimensions, architecture and generativity. The premises are based on five concepts: value-in-architecture, value-in-connectivity, fundamental asset for value creation, mutual dependence of modular and layered modular assets, and re-evaluation of value propositions. The proposed premises offer a basis for understanding value creation of this class of services, and guidance for manufacturing firms designing digitalized product platforms.

  • Black males and white masculinity in four Renaissance tragedies of blood
  • 2008
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • The aim of this study is to look at how the black North African man is repre-sented in relation to white men in four Renaissance tragedies of blood: Shake-speare’s Titus Andronicus, the multi-authored Lust’s Dominion, William Rowley’s All’s Lost by Lust, and Thomas Rawlins’ The Rebellion. While previous studies have traced the most common racist tropes in 16th and 17th century lit-erature, such as the demonization trope and the animality trope (e.g. Hall), and the historical presence of modern stereotypes of the black man (Jones, Barthelemy, Tokson), they have not looked at Renaissance discourses of white masculinity and their relationship to the construction of the black man. There-fore, the present study focuses on the articulation of the black man as a gendered concept, and specifically its racialized difference in relation to localized white masculinity. I argue that black masculinity is not its own discourse that is separate from white masculinity, but rather is fashioned using the same strategies that enabled white masculine self-fashioning in the sixteenth and seventeenth centuries, i.e. through the manipulation of discourses to enhance the self and discredit male enemies or rivals. I specifically look at four discourses that were important to the social perception and thus construction of white masculinity in the Renais-sance: relationships to women and the feminine, honour, sociality (humour), and ambition. What emerges as an overall feature in all four tragedies of blood is that there is not a polar distinction between black and white masculinity. My approach builds on Michel Foucault and the idea that discourses structure society and relationships of power. It is also indebted to Reinhardt Koselleck’s theory that concepts have a history, i.e. a contemporary polemic edge in Renaissance even as other meanings looked to the past, and others to the future. I argue that the difference in English tragedies of blood between the black men and the white men in the relationship to honour is temporal; that the distinction in vice and humour is a matter of attitude; and that black men have a blurred rather than distinct relationship to femininity. Racialization oc-curs through the discourse on blackness but also through everyday Renaissance discourses in historically contingent ways.

  • The Evolution of a New(s) Genre
  • 2004
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • This thesis describes and analyzes how the online newspaper genre has evolved since its inception on the Internet in the mid-nineties. The overall research question is: What characterizes the online newspaper genre evolution? The thesis is based on both synchronic and diachronic studies with a multimethod approach (including six different studies involving, e.g., interviews, questionnaires and web site analyses) intended to provide a comprehensive picture of this genre evolution. On the basis of genre theory, the thesis proposes a framework for understanding online newspaper genre evolution, integrating design (layout) aspects with publisher and audience views. Applying this framework to the collected empirical material, the thesis presents a comprehensive and integrated view of this evolution. Over time, online newspapers have evolved into a specific digital genre, with genre characteristics such as content and form, distinguishing them from other digital genres. However, this rapid development has also lead to diversities in form and function, triggering both academics and practitioners to seek ways to design for consistency within the genre. Several factors have influenced the online newspaper genre evolution, e.g., inhouse attitudes, business model shifts and technological progress at the publishers’ side. The audience demographics, habits and preferences have also changed. The layout of the online newspapers has been altered into long pages stuffed with content like news streams, headlines, photos, and services not possible in the printed edition. There has also been a shift towards frequent updates throughout the day and more content produced for the web. In addition, the thesis contributes to digital genre theory by modifications relevant to the online newspaper genre. For example, the concepts of genre awareness and genre interdependence are elaborated, a framework for identifying genre characteristics is proposed, and the concept “positioning” is introduced. Further, the thesis also contributes with implications for online newspaper design and publishing with longitudinal mappings of online newspaper layout and the habits and preferences of the audience.

  • Planerad processorienterad omvårdnad - nytta och implementering
  • 2010
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • To ensure the provision of good and safe nursing care in the ward, the nursing needs of each patient should be established and clearly documented in the form of care plans in his/her medical record. There is a lack of scientific evidence of the benefits of this method of working as well as why this part of the nursing process is not always successful. The main aim of this thesis was to describe the assessment and decision-making process pertaining to nursing needs performed by nurses, to evaluate the consequences of planned, process oriented nursing care and to identify the factors and conditions that have had an impact on the implementation of individual care plans (ICP) and standardized care plans (SCP). In studies I and III, qualitative methods were used. In study I, data collection and analysis were carried out by means of Grounded theory. Study III was conducted by means of directed content analysis and guided by “The Promoting Action on Research Implementation in Health Services framework”. In studies II and IV, quantitative methods were employed. The benefits of a planned, process oriented method of working involving documentation of care plans have been investigated from the perspective of both the patient and the nurse. Nurses who applied the process oriented method adopted a nursing perspective in the assessment of and decision making pertaining to the patient’s nursing needs, which was not the case with nurses who did not work in this way and who instead exhibited a more medical approach (I). Patients cared for in wards where care plans were documented reported being more involved and that the care was more tailored to their individual needs compared to those not cared for in this manner (II). Leadership that prioritises the development of nursing care is essential for the implementation and continued use of ICPs and SCPs. Another important factor was the presence of internal facilitators in the ward in the form of nurses with a clear mandate to work with these issues. The nurses reported that they did not discuss scientific evidence as a basis for performing planned process oriented nursing care and that they did not listen to patient experiences to any great extent (III, IV). The conclusion is that structured, process oriented nursing care based on written care plans probably promotes the nursing perspective and enables patient participation. Leadership as well as facilitators with a clear role and mandate are important factors in the implementation of this method of working and scientific evidence is of less importance.

  • On Oral Health-Related Quality of Life in Swedish Young Adults
  • 2015
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • Unga vuxna i Sverige har vuxit upp med fri tandvård till och med det år de fyller 19 år och de upplever ofta en god munhälsa. Snabba samhällsförändringar har bl a medfört sämre ekonomi för många unga och detta kan ha påverkat deras tandvårdsbesök och deras prioriteringar vad gäller tandvård. Det övergripande syftet med avhandlingen var att utforska unga vuxnas syn på tandvården, deras munhälsa och munhälsorelaterade livskvalitet (OHRQoL).Avhandlingen baseras på fyra studier. I Studie I undersöktes unga vuxnas syn på tandvården. Studie II undersökte och beskrev unga vuxnas syn på sin munhälsa och OHRQoL. I Studie III beskrevs och analyserades mätinstrument för OHRQoL ur ett folkhälsoperspektiv och i Studie IV beskrevs hur unga vuxna ser på tre mätinstrument för OHRQoL. I Studie I, Studie II och Studie IV samlades data in genom kvalitativa intervjuer. Urvalet var strategiskt i förhållande till ålder (21-29 år), kön (hälften kvinnor) och utbildning (gymnasienivå/mer). De flesta deltagarna i studierna besökte tandvården regelbundet. I Studie III gjordes sökningar i databasen PubMed för att finna mätinstrument för OHRQoL. Data i Studie I analyserades genom komparativ metod som är inspirerad av ”Grounded Theory”. I Studie II, Studie III och Studie IV genomfördes dataanalysen med kvalitativ innehållsanalys.Resultaten visade att unga vuxna var nöjda med den tandvård de erhållit men att de hade speciella önskemål och krav på denna (Studie I). Unga vuxna beskrev sin munhälsa som god men angav trots det en mängd olika munhälsoproblem. Deras upplevda kontroll över sin OHRQoL var relaterad till deras syn på sin framtida munhälsa i relation till tidigare erfarenheter av tandvården och synen på sin egen munhälsa (Studie II).I Studie III genererade datasökningen 22 mätinstrument för OHRQoL. Mätinstrumenten analyserades utifrån deras teoretiska utgångspunkter och i relation till fyra principer för folkhälsoarbete (empowerment, medinflytande, holism, rättvisa). Aspekter av de fyra principerna återfanns i varierande grad hos alla mätinstrumenten varav de flesta hade sin utgångspunkt i sjukdomsinriktade teorier. I Studie IV framkom att de unga vuxnas upplevelse av sin egen munhälsa hade betydelse för deras syn på de tre undersökta mätinstrumenten för OHRQoL. Alla mätinstrumenten ansågs ha för- och nackdelar men bedömdes som ungefär likvärdiga.Konklusionen är att unga vuxnas OHRQoL är beroende av deras tidigare erfarenheter från tandvården och deras tidigare och nuvarande munhälsa samt i deras syn på sin framtida munhälsa. Principer för folkhälsoarbete uppfylldes i varierande grad i analyserade mätinstrument för OHRQoL och unga vuxna ansåg att mätinstrumenten var ungefär likvärdiga. Mätinstrumenten var i huvudsak sjukdomsinriktade. Det saknas ett speciellt instrument för att mäta unga vuxnas munhälsorelaterade livskvalitet.
