- Drawing on an empirical study of public transport, this paper studies interactive value formation at the provider—customer interface, from a practice—theory perspective. In contrast to the bulk of previous research, it argues that interactive value formation is not only associated with value co-creation but also with value co-destruction. In addition, the paper also identifies five interaction value practices — informing, greeting, delivering, charging, and helping — and theorizes how interactive value formation takes place as well as how value is intersubjectively assessed by actors at the provider—customer interface. Furthermore, the paper also distinguishes between four types of interactive value formation praxis corresponding with four subject positions which practitioners step into when engaging in interactive value formation.

Ingår i: Marketing Theory. - : Sage Publications. - 1470-5931 .- 1741-301X.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this conceptual article is to both provide a critical review of research into value co-destruction (VCD) and outline a common conceptual framework in order to better understand and guide future research into VCD and value co-creation (VCC). This review finds that the VCD stream of research has followed two lines of enquiry: one that highlights the role of resources and service systems and another that focuses on practices. It further finds that some prior research has argued that a direct and reciprocal relationship exists between VCD and VCC, captured in the concept of interactive value formation (IVF). A synthesizing IVF framework is outlined which suggests that the alignment and misalignment both within practices and in-between different practices determines IVF, that is, VCD and VCC. The framework further suggests that IVF is both enabled and constrained by resources and service systems.

- Chronically elevated serum levels of serum amyloid A (SAA) are linked to increased risk of cardiovascular disease. However, whether SAA is directly involved in atherosclerosis development is still not known. The aim of this study was to investigate the effects of adipose tissue-derived human SAA on atherosclerosis in mice. hSAA1(+/-) transgenic mice (hSAA1 mice) with a specific expression of human SAA1 in adipose tissue were bred with ApoE-deficient mice. The hSAA1 mice and their wild type (wt) littermates were fed normal chow for 35 weeks. At the end of the experiment, the mice were euthanized and blood, gonadal adipose tissue and aortas were collected. Plasma levels of SAA, cholesterol and triglycerides were measured. Atherosclerotic lesion areas were analyzed in the aortic arch, the thoracic aorta and the abdominal aorta in en face preparations of aorta stained with Sudan IV. The human SAA protein was present in plasma from hSAA1 mice but undetectable in wt mice. Similar plasma levels of cholesterol and triglycerides were observed in hSAA1 mice and their wt controls. There were no differences in atherosclerotic lesion areas in any sections of the aorta in hSAA1 mice compared to wt mice. In conclusion, our data suggest that adipose tissue-derived human SAA does not influence atherosclerosis development in mice.

How Has Digitalisation Influenced Value in the Music Market?

Tidskriftsartikel (refereegranskat)abstract
- This paper focuses on how digitalisation has influenced actors’ value determination and value creation in the Swedish music market. It draws on the service-dominant logic (SDL) and the service ecosystem perspective to conceptualise value as co-created through the integration of resources by multiple actors in service exchange, enabled and constrained by institutions and institutional arrangements. Empirically, we draw on a qualitative study of the digitalisation of the Swedish music market that consists of fifty-two interviews with various actors. The findings suggest that digitalisation has influenced service engagement and consequently value creation and determination for various actors, and especially for consumers and producers. This paper contributes by integrating SDL and the service ecosystem perspective into music business research in a novel way to promote a deeper understanding of value, value determination, and value co-creation. This paper also contributes to SDL by suggesting that both value-in-exchange and value-in-use are important aspects of value determination and value co-creation.

Parameter Selection in the Parameter Estimation of Grade Transitions in a Polyethylene Plant
- 2015

Tidskriftsartikel (refereegranskat)abstract
- A polyethylene plant at Borealis AB is modelled in the Modelica language and considered for parameter estimations at grade transitions. Parameters have been estimated for both the steady-state and the dynamic case using the JModelica.org platform, which offers tools for steady-state parameter estimation and supports simulation with parameter sensitivies. The model contains 31 candidate parameters, giving a huge amount of possible parameter combinations. The best parameter sets have been chosen using a parameter-selection algorithm that identified parameter sets with poor numerical properties. The parameter-selection algorithm reduces the number of parameter sets that is necessary to explore. The steady-state differs from the dynamic case with respect to parameter selection. Validations of the parameter estimations in the dynamic case show a significant reduction in an objective value used to evaluate the quality of the solution from that of the nominal reference, where the nominal parameter values are used.

The Effect of Service Guarantees on Service Recovery
- 2003
-
Ingår i: International Journal of Service Industry Management, 14:(1), 36-58, 2003.
-
Tidskriftsartikel (refereegranskat)abstract
- Service guarantees have been attributed the benefit of improving the overall service of a service provider. However, little research has been carried out within the area. This article focus on one aspect of the service guarantee, the effects that service guarantees may have on service recovery. Critical incident data were collected using the critical incident interview technique with customers of RadissonSAS, a worldwide hotel chain using a service guarantee. One contribution of this article is that the interviews convey that the implicit guarantee may serve as a risk reducer, which contradicts and adds to previous research. Previous research states that only the explicit guarantee has these benefits. In this case, the guarantee does not reduce risk in the purchase or consumption stage, but after the consumption when the service has failed, as the customer finds out about the guarantee in the recovery situation. Another contribution of this article is that service guarantees are found to influence the outcome of service recovery as it affects how employees behave to recover the customer. Keywords: Service guarantee, Service Recovery, RadissonSAS

Lifestyle entrepreneurs and their identity construction : A study of the tourism industry
- 2016
-
Ingår i: Tourism Management. - : Elsevier. - 0261-5177 .- 1879-3193. ; 56, s. 96-105
-
Tidskriftsartikel (refereegranskat)abstract
- The present study takes issue with the uniform conceptualization of lifestyle entrepreneurs in previous research by drawing on identity theory and life-story interviews with lifestyle entrepreneurs in Norway. This article aims to show how lifestyle entrepreneurs create their entrepreneurial identity and how this identity informs both their entrepreneurial actions in different ways and how they manage the enterprise. On the basis of a narrative understanding of identity this article differentiates between two dimensions of identity construction: (1) socially and culturally embedded versus independent, and (2) flexible versus stable. The main contribution of this study is that embedded or independent and also flexible or stable identity constructions dominate the identity-construction process for individual lifestyle entrepreneurs. On the basis of the latter this article reports four narrative types of lifestyleentrepreneur identity construction: (1) the modern, (2) the loyal, (3) the freedom-seeking, (4) and the post-modern lifestyle entrepreneur.

'Made to Run' : Biopolitical marketing and the making of the self-quantified runner
- 2019
-
Ingår i: Marketing Theory. - : Sage Publications. - 1470-5931 .- 1741-301X. ; 19:3, s. 347-366
-
Tidskriftsartikel (refereegranskat)abstract
- While previous critical marketing research on co-creation has focused on how consumers’ cognitive and social abilities are governed, this article focuses on how firms’ marketing strategies attempt to govern every aspect of consumers’ lives. By drawing on a biopolitical framework and a study of Nike+, a marketing system for runners which Nike has developed around its self-tracking devices, three biopolitical marketing dimensions were identified: the gamification of the running experience, the transformation of running into a competitive activity and the conversion of running into a social activity. In identifying these marketing dimensions, the study demonstrates how self-tracking affordances are deployed in the development of a biopolitical marketing environment that tames, captures and appropriates value from different aspects of consumers’ lives, including – and combining – their social behaviours, cognitive capacities and bodily conducts. This article contributes to critical studies of value co-creation by focusing on the tamed self-tracking body as a resource for value creation, but also by demonstrating that consumers engage, through cognitive labour, in the production of the biopolitical environment that leads to their exploitation.

Self-tracking, datafication and the biopolitical prosumption of life
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The marketing literature has both celebrated and critically scrutinised the active engagement of consumers in value-creation processes. These opposing analyses share a focus on the mobilisation of consumers’ social and cognitive abilities for value creation. This thesis contributes to this discussion by exploring how diverse aspects of consumers’ lives become involved in value creation, leading the entirety of life to become a resource. In particular, the thesis focuses on the popular consumption phenomenon of self-tracking, which allows and enables consumers to track, quantify and datafy diverse facets of their lives. Drawing on data from two empirical studies, which were based on interviews and observational netnography, the thesis engages with the notion of biopolitical marketing to analyse the extraction and appropriation of value from consumers’ lives.The thesis contributes to the critical marketing literature by advancing the understanding of the biopolitical nature of marketing in extracting value from consumers’ lifestyles and subjectivities. The theoretical contributions include the notions of the “biopolitical prosumption of life”, the “prosumed self” and the “prosuming self”. The “biopolitical prosumption of life” entails the “creation of worlds” that allow and enable the development of market-aligned subjectivities, which can generate value for corporate interests. The notions of the “prosumed self” and the “prosuming self” are introduced to frame and elucidate these subjectivities. The empirical findings suggest that marketing interventions foster the development of marketing environments (“worlds”) that seek to contain consumers while allowing them to act freely, albeit in ways that augment the value that can be extracted and appropriated.

Brand volunteering : Value co-creation with unpaid consumers
- 2015

Tidskriftsartikel (refereegranskat)abstract
- Through collaborative marketing approaches, companies invite consumers to provide unpaid contributions. Companies commonly do this in the realm of brand communities. The key question this article addresses is how can a company lead consumers to offer unpaid contributions to brands as an act of free will? To answer this question, we develop a framework based on volunteer commitment research to study the actions a company takes to engage consumers in unpaid work for brands. We use this framework to analyse the online collaboration promoted by the carmaker Fiat with its brand community of Alfa Romeo enthusiasts (Alfisti). The research introduces the notion of brand volunteers, that is, brand enthusiasts who are committed to providing unpaid work for the exclusive benefit of the brand. With this notion, the article discusses the possibility of exploiting consumers in value co-creation and the existence of compromises, signifying an agreement between two collaborating parties in which one party (in our case, the consumer) temporarily puts aside possible sources of conflict.
