- The sharing economy has evolved and spread to various sectors of the economy. Its early idea linked to the creation of more sustainable uses of resources. Since then, the development of the sharing economy has included a professionalization with self-employed suppliers rather than peers, and the question is whether the platforms following this development maintain the focus on sustainability. This paper describes and classifies the sustainability connotation of sharing economy platforms. It analyses 121 platforms derived through social media analytics to figure out whether they describe themselves as sustainable. The findings suggest that the sustainability connotation closely connects to specific sectors such as fashion, on-demand services and logistics. Meanwhile, the dominant role model platforms do not communicate about being sustainable. These findings contribute to previous research through (1) giving a systematic empirical account on the way various sharing economy platforms describe themselves in terms of sustainability, (2) pointing out the differences among the platforms, and (3) indicating the diversity in sustainability connotation among various sectors of the economy.

Demonstration projects in sustainable technology : The road to fulfillment of project goals
- 2019

- Publicly funded demonstration projects represent a critical intermediate step between basic R&D on the one hand, and large-scale commercialization of new sustainable technology on the other. However, these projects often suffer from various technical and nontechnical difficulties, frequently fail to meet objectives, and sometimes stall despite the best intentions of their facilitators. This paper reports on a multiple case study of 21 demonstration projects in the area of sustainable technology set in Sweden and offers two contributions. First, it maps the project-internal and external factors that allow or prohibit demonstration projects to reach their goals. Second, it suggests a process model outlining the key activities for setting up a new demonstration project. By doing so, the paper provides important implications for the process of developing and commercializing sustainable technologies. The escalating environmental crisis in particular underscores the need for new knowledge about how cleaner and more sustainable technologies can be applied.

Evaluating research : A multidisciplinary approach to assessing research practice and quality
- 2016

Tidskriftsartikel (refereegranskat)abstract
- There are few widely acknowledged quality standards for research practice, and few definitions of what constitutes good research. The overall aim was therefore to describe what constitutes research, and then to use this description to develop a model of research practice and to define concepts related to its quality. The primary objective was to explore such a model and to create a multidisciplinary understanding of the generic dimensions of the quality of research practice. Eight concept modelling working seminars were conducted. A graphic representation of concepts and their relationships was developed to bridge the gap between different disciplines. A concept model of research as a phenomenon was created, which included a total of 18 defined concepts and their relationships. In a second phase four main areas were distilled, describing research practice in a multidisciplinary context: Credible, Contributory, Communicable, and Conforming. Each of these was further specified in a concept hierarchy together with a defined terminology. A comprehensive quality model including 32 concepts, based on the four main areas, was developed for describing quality issues of research practice, where the model of research as a phenomenon was used to define the quality concepts. The quality model may be used for further development of elements, weights and operationalizations related to the quality of research practice in different academic fields. (C) 2015 The Authors.

Organization outside organizations : The significance of partial organization
- 2011

Ingår i: Organization. - : SAGE Publications. - 1350-5084 .- 1461-7323. ; 18:1, s. 83-104

Tidskriftsartikel (refereegranskat)abstract
- It is common practice in organizational research to restrict the concept of organization to formal organizations, and to describe the world outside these entities by such other concepts as institutions or networks. It is argued in this article that the concept of organization can be fruitfully broadened to include some aspects of the order that exists outside and among organizations. A broader concept includes not only complete, formal organization, but also 'partial organization'. Both types of organization are based on decisions, but whereas complete organizations have access to all elements of organization, partial organization is based on only one or a few of these elements. Like complete organization, partial organization is a common phenomenon that not least characterizes much of the contemporary global order. The authors discuss how partial organization arises, how and why institutions and networks sometimes become organized, and the consequences of organization for change, transparency and accountability.

Can upstream ecosystems ensure safe drinking water—Insights from Sweden
- 2020

Ingår i: Ecological Economics. - : Elsevier. - 0921-8009 .- 1873-6106. ; 169

Tidskriftsartikel (refereegranskat)abstract
- Clean water is not only the product of expensive treatment technology, but also of upstream ecosystems. Yet, the effect of land use on downstream water quality is poorly understood. We investigate the value of ecosystem water purification as an input to the production of drinking water in Sweden. We employ a recently modified empirical approach, complementing ex-ante modelling. We capture plant operator behaviour, rather than assuming rational individuals that value ecosystem services as a factor in the drinking water production function. The GMM technique is applied to estimate the marginal contributions of different land uses to water quality and chemical costs of treatment plants. The analysis is based on upstream land-use data, raw water quality, and chemical costs for a large share of Sweden's municipal surface water treatment plants, for the period 2000 to 2012. Our results show that upstream forests lead to lower levels of E. coli (a pathogen associated with disease outbreaks) in downstream water and indicate the same effect on turbidity (not significant). We also find that turbidity increases treatment costs, but the effect of E. coli remains unclear. Consequently, in addition to water treatment equipment, decision-makers should consider investment in upstream ecosystems.

Robustness to strategic uncertainty
- 2014

- We introduce a criterion for robustness to strategic uncertainty in games with continuum strategy sets. We model a player's uncertainty about another player's strategy as an atomless probability distribution over that player's strategy set. We call a strategy profile robust to strategic uncertainty if it is the limit, as uncertainty vanishes, of some sequence of strategy profiles in which every player's strategy is optimal under his or her uncertainty about the others. When payoff functions are continuous we show that our criterion is a refinement of Nash equilibrium and we also give sufficient conditions for existence of a robust strategy profile. In addition, we apply the criterion to Bertrand games with convex costs, a class of games with discontinuous payoff functions and a continuum of Nash equilibria. We show that it then selects a unique Nash equilibrium, in agreement with some recent experimental findings.

How do different stakeholder groups within an open source software project influence the project's development: a case study of OpenSimulator
- 2023

Tidskriftsartikel (refereegranskat)abstract
- Purpose This research investigates how the value creation interests and activities of different stakeholder groups within one open source software (OSS) project influence the project's development over time. Design/methodology/approach The authors conducted a case study of OpenSimulator using textual and thematic analyses of the initial four years of OpenSimulator developer mailing list to identify each stakeholder group and guide our analysis of their interests and value creation activities over time. Findings The analysis revealed that while each stakeholder group was active within the OSS project's development, the different groups possessed complementary interests that enabled the project to evolve. In the formative period, entrepreneurs were interested in the software's strategic direction in the market, academics and SMEs in software functionality and large firms and hobbyists in software testing. Each group retained its primary interest in the maturing period with academics and SMEs separating into server- and client-side usability. The analysis shed light on how the different stakeholder groups overcame tensions amongst themselves and took specific actions to sustain the project. Originality/value The authors extend stakeholder theory by reconceptualizing the focal organization and its stakeholders for OSS projects. To date, OSS research has primarily focused on examining one project relative to its marketplace. Using stakeholder theory, we identified stakeholder groups within a single OSS project to demonstrate their distinct interests and how these interests influence their value creation activities over time. Collectively, these interests enable the project's long-term development.

Nowcasting COVID-19 statistics reported with delay : A case-study of Sweden and the UK
- 2023
-
Ingår i: International Journal of Environmental Research and Public Health. - : MDPI. - 1661-7827 .- 1660-4601. ; 20:4
-
Tidskriftsartikel (refereegranskat)abstract
- The COVID-19 pandemic has demonstrated the importance of unbiased, real-time statistics of trends in disease events in order to achieve an effective response. Because of reporting delays, real-time statistics frequently underestimate the total number of infections, hospitalizations and deaths. When studied by event date, such delays also risk creating an illusion of a downward trend. Here, we describe a statistical methodology for predicting true daily quantities and their uncertainty, estimated using historical reporting delays. The methodology takes into account the observed distribution pattern of the lag. It is derived from the "removal method"-a well-established estimation framework in the field of ecology.

Bootstrapping Error Component Models
- 2001
-
Ingår i: Computational statistics (Zeitschrift). - : Physica Verlag. - 0943-4062 .- 1613-9658. ; 16:2, s. 221-231
-
Tidskriftsartikel (refereegranskat)abstract
- This paper proposes several resampling algorithms suitable for error component models and evaluates them in the context of bootstrap testing. In short, all the algorithms work well and lead to tests with correct or close to correct size. There is thus little or no reason not to use the bootstrap with error component models.
