    Afasi och narrativt aktörskap – mediebilder, självberättelser och multimodala litteracitetspraktiker2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Aphasia is an aquired language disability, most commonly caused by stroke. Since aphasia involves difficulties producing and/or understanding language, written as well as spoken, it entails a reduced ability and opportunity to author one’s own narrative. In the face of this reduced narrative agency (Baldwin, 2005), people who acquire aphasia need to renegotiate their identity. To do so they mirror their stories of self in social structures, including the contemporary communication landscape in which digital tools play an important part, but also norms and attitudes – strongly influenced by the media – towards people with language disabilities. Drawing on theories about the interplay between agency and social structures, this doctoral thesis aims to – by studying media representations of people with aphasia, stories of self authored by people with aphasia and literacy practices within a group of people with aphasia – examine narrative agency in people who live with aphasia in a society influenced by textual and digitally mediated communication.Three studies (A-C), presented in four articles, were conducted. Study A aimed at investigating narrative types in Swedish newspaper articles about living with aphasia. A majority of the newspapers contained stories in which the person with aphasia was talked aboutrather than talked to. In the few cases in which the person was given voice (or was assisted by a vicarious voice), the stories were mainly framed as successs stories. Study B then aimed at examining stories of self authored by nine individuals with aphasia who were interviewed and then observed in social media. They applied a variety of strategies to manage their stigma (Goffman, 1963)and to navigate identity dilemmas (Bamberg, 2011). In addition, the participants experienced a higher degree of narrative agency when communicating in social media than in other practices. The key to this enhanced narrative agency was the multimodality offered by the digital tools. Finally, study C aimed at describing literacy practices within a group of people with aphasia attending an aphasia course at a Swedish folk high school. Ethnographic data were collected during three weeks. The group’s narrative agency was strongly influenced by the use of digital screens to access multimodal literacy practices and by co-creation of literacy events between group members in which they used each other’s abilities. To discuss the overall findings from all three studies, Bourdieus thinking tools linguistic capital, linguistic markets and legitimate language (1991)were used. Although aphasia means partial language loss, some linguistic capitals may remain. When a linguistic market includes multiple modalities, a person with aphasia may chose ways of communication based on her remaining abilities. Thus, her narrative agency increases when her remaining linguistic capitals correspond to what is considered legitmate language within a certain linguistic market. That was the case when the participants in study B and C engaged in multimodal literacy practices. But when the stories of people with aphasia are told in Swedish newspapers, they are portrayed with a low degree of narrative agency. In addition, the newspaper stories are framed as success stories, meaning that when people with aphasia renegotiate their stories of self, they mirror their stories in grand narratives about happy endings. Further research is suggested about representations of people with aphasia in other media types (with a higher degree of multimodality), but also about how the linguistic capitals of people with aphasia interact with other forms of social capital such as gender and class.

    Doing well by doing good: The business model innovation process for sustainability in farm-based biogas production2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Research on innovation that leads to change and adaptation in dynamic business environments has increased rapidly in recent decades. This doctoral thesis, which focuses on business model innovation (BMI), contributes to that research with its examination of how businesses can alter their structures to create, deliver, and capture greater economic value as well as environmental and social value. The overarching aim of the thesis is to explore how the business model innovation process for sustainability (BMIpfS) can contribute to profitable biogas production at Swedish farm businesses. Biogas, which is a renewable energy resource produced from microbial decomposition of organic material in an oxygen free environment, can be used to produce heat, electricity, or vehicle fuel. The thesis examines the initiation, implementation, and use of the BMIpfS at biogas-producing farms in ways that support the development of business models for sustainability (BMfS). In addition to economic value, a BMfS enables farm businesses and external stakeholders (e.g., municipalities and local companies) to capture environmental value and social value from biogas production and create business cases for sustainability (BCfS) that can improve biogas profitability.

    Both an inductive and deductive reasoning approach is taken in this research that is presented in a case study, two action research studies, and two survey studies. The case study identifies and describes various success factors for BMI for sustainability in a biogas network. The action research studies explore how BMI process can be modified to address sustainability considerations and the outcomes useful for supporting stakeholder collaboration and facilitating the development of a BMfS. The survey studies investigate how the farm businesses’ corporate sustainability strategies and stakeholder considerations influence the development of BMfS and the creation of BCfS. All studies were conducted at farm businesses in Sweden. The data were collected in interviews, workshops, and questionnaires.

    The results from this research show that BMI for sustainability takes place in three main phases: the pre-phase, the ongoing phase, and the post-phase. Based on these three phases, the BMIpfS Framework is developed. The Framework illustrates how a business model (BM) can be changed and adapted to realize sustainable value creation. Several factors determine the success of the BMIpfS Framework at biogas-producing farm businesses. In the pre-phase, these factors include a long-term perspective on biogas profitability, integration of sustainability considerations into business strategies, promotion of cooperation with customers, and the establishment of interactions with the consumer markets. Use of the Flourishing Business Canvas tool in the ongoing phase can enhance external stakeholders’ understanding of BMs and BMI, and can promote idea generation for the BMfS. Sustainability-oriented BM prototypes are used in the post-phase to support network collaboration in development of BMfS and in the creation of BCfS, both of which are intended to increase biogas profitability by solving sustainability issues.

    This thesis contributes to the literature with its findings on how the BMIpfS Framework can be used in organizational changes. These findings show how an organization can move from its existing BM to a more sustainability-oriented BM. The thesis identifies the internal and external antecedents related to the initiation and implementation of the BMIpfS and offers new insights on the development of BMfS through the integration of sustainabil­ity considerations using business modelling tools that facilitate BM experimentation and stakeholder collaboration. Moreover, the thesis explains how use of the BMIpfS Framework can create sustainability-oriented BM prototypes that enhance network BM collaboration with stakeholders in the value chain (i.e. BMfS development and BCfS creation). As far as practical contributions, the thesis highlights the usefulness of the BMIpfS Framework in farm-based biogas production. With the BMIpfS Framework, the thesis presents a structured approach that practitioners can follow in initiating and implementing sustainability-oriented changes to their existing BMs. Practitioners who want to increase the profitability of their biogas production through sustainability should initially focus their BMI activities on the business infrastructure (key partner identification and interaction) and customer interface (relationships, distribution channels, and segments) of existing BMs.

    This thesis ultimately concludes that biogas-producing farm businesses should initiate and implement a BMIpfS that leads to economic, environmental, and social value creation. Stakeholder considerations and interactions are key factors in all phases of BMIpfS. In this process, sustainable business modelling tools and BM prototype development can be used to facilitate incremental sustainability-oriented changes to existing BMs. The BMIpfS Framework has an important role for the development and implementation of BMfS in the biogas industry as a contributor to the circular economy that features renewable and sustainable energy systems.
