  • Justifying the Value of Open Source
  • 2012
  • Ingår i: Proceedings European Conference on Informations Systems. - : Association for Information Systems. - 9788488971548
  • Konferensbidrag (refereegranskat)abstract
    • Over the last decade, free and open source software (FOSS) has gradually become recognized by different actors in society outside FOSS communities and increasingly integrated in corporate software development, challenging proprietary software practices and establishing new open source companies. Literature describing this transition is focusing a narrow view on the value of using FOSS, mainly understanding it as an efficient alternative to established models for software development. This is not sufficient to fully understand the uptake of FOSS into companies. In order to gain a deeper understanding of this, there is a need to articulate a wider range of different values associated with FOSS and how they interplay in the intersection of corporations and movements. To do this we propose the order of worth framework developed by French sociologist Luc Boltanski and colleagues, which focus on the arrangements of value logics as an analytical strategy to understand how values form strong or weak arrangements in processes of institutionalization. By applying the framework on key texts from the free and open source software movement as well as on a an interview study with professional software developers employed by firms, we set out to identify how values associated with FOSS become justificatory arrangements that give legitimacy to FOSS and how these arrangements change over time, from the early free software movement to the emergent uptake of FOSS in contemporary professional software development. By understanding how justificatory logics come to play and interplay, corporations that want to adopt FOSS can better manage their engagement in FOSS activities. Keywords: Free and Open Source Software, Orders of Worth, Justification logics, Value of Open Source.

  • RESTRICTING OR RELEASING PASSION FOR INNOVATION – THE CASE OF PROFESSIONAL OPEN SOURCE SOFTWARE DEVELOPMENT
  • 2012
  • Ingår i: ISA RC52 Sociology of Professional Groups, Interim Conference, Ipswich UK 11-12 November.
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • Companies are seeking methods to become more innovative. One strategy is to introduce disruption to promote innovation. An example of this is the uptake of Open Source Software (OSS) technologies, methods and mindsets by commercially driven actors. Contrary to the firm, open source is associated with hackers driven by a passion emerging out of a community or peer based innovation model. The fact that these hackers are highly engaged in collaboration outside the limits of the organisation, have meant that companies start to perceive them as potential resources enabling them to extend their innovative capacity. The passionate hacker is seen as an autonomous and positive disruptive force that can promote innovation for the company. This paper is based on an interview study with 30 software developers from ten companies that have chosen to introduce OSS as a vehicle for innovation. Theoretically, passion is understood as an urge to develop high quality software beyond the demarcations of the firm; it is a matter of craft or art, and the paper focuses on how this perception of the passionate hacker guides these professional developers at work. Thus, it is analysed how the discourse on the passionate hacker is transformed when it is adopted by developers working in a firm that expects organisational commitment. By studying the reshaping of these software developers’ practices, we show how OSS passion for disruptive innovation is transformed in a professional work environment, but also how disruption creates new demarcations when open source ‘culture of passion’ is introduced in firms.

  • Spaces of Accountability - Understanding Worth in Distributed Innovation Work
  • 2012
  • Ingår i: Egos Summer Workshop "Spaces of work", Rhodes 23 - 26 may, 2012.. - : European Group for Organizational Studies (EGOS).
  • Konferensbidrag (refereegranskat)abstract
    • As a result of various driving forces, R&D and innovation processes are increasingly opened up for external influences and resources. This has lead to a changing nature of innovation work to become more distributed, networked and fragmented. In companies, a consequence of this is that hierarchically defined directives are transformed to lateral agreements. For the employee, a consequence of this is that they are increasingly expected to justify the value of distributed innovation practices in relation to both their firm and external contributors of innovation, and by doing so they involve themselves in a process were accountability is horizontally redistributed. In order to analyze this process, we use a case of open source software development, were developers from eleven firms, using open source in their professional practice, are interviewed. We show how distributed innovation processes leave the professional developer with the responsibility to select and assure that external resources becomes advantageous to their work, and how they use different types of justification to account for the value of this appropriation. We identify how different spaces of accountability are formed, potentially leading to tensions between different logic of worth. Keywords: distributed innovation, developers, logic of justification, tensions, accountability

  • The effects of PACS on radiographer’s work practice
  • 2007
  • Ingår i: Radiography. - London : W.B. Saunders Co. Ltd.. ; 13:3, s. 235-240
  • Tidskriftsartikel (refereegranskat)abstract
    • This paper identifies and analyses the effects of picture archiving and communica- tion systems (PACS) on radiographers’ work practice. It shows that the introduction of PACS did not simply entail the transfer of data and information from the analogue world to the digital world, but it also led to the introduction of new ways of communicating, and new activities and responsibilities on the part of radiography staff. Radiographers are called upon to work increasingly independently, and individual practitioners require higher levels of professional expertise. In all, this paper demonstrates that new technical solutions sometimes lead to sub- stantial changes in responsibilities in work. In this example, the radiographers’ work practice has become more highly scientific and they are enjoying a higher level of prestige.

  • The Worth of Opening up Developmental Work - Justifying a New Business Driven Spirit of Open Source Software Development
  • 2011

    • Free and open source software development (FOSS) used to be associated with an ideologically driven movement built around communities of voluntary members, organizing resistance against proprietary software development. Today, however, software firms perceive FOSS as a source of innovation. Previous research has investigated what this change has meant to movement driven FOSS, but we still need more knowledge about the professional programmers and their way of organize business driven open source software development in their daily practice. This article investigates the interpretative guidelines or justifying arrangement that guide their use of FOSS. The analysis is based on 30 interviews that were done during 2008-2009 with programmers who were employed either by software firms that had come to a point where they started to adopt open source, or by firms that always based their business on open source software development. Theoretical concepts that were used in the analysis mainly derive from the economic sociology of Luc Boltanski and Laurent Thevénot, and the results indicate the emergence of a new spirit of business driven open source, consisting of a combination of different justificatory logics. This new spirit is described as an arrangement guiding how professional programmers in today’s software industry perceive the worth of using open source code in their developmental work.

  • The experience of participation in a brief cognitive behavioral group therapy for psychologically distressed female university students
  • 2014
  • Ingår i: Journal of Psychiatric and Mental Health Nursing. - Malden, United States : Wiley. - 1351-0126 .- 1365-2850. ; 21:8, s. 679-686
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim of this study was to elucidate the experience of participation in four sessions of cognitive behavioural group therapy for psychological distress for female university students' (n = 19), aged 22-45 years. Data were gathered with semi-structured interviews during March and April 2008 and analysed according to thematic content analysis. The results identified four themes: 'Gaining knowledge and understanding', 'Becoming more balanced and positive in thinking', 'Feeling more self-confident and in control' and 'Opportunities for practice and in-depth reflections'. Future recommendations include an increase in sessions from four to five, with one booster session to follow-up on newly acquired skills.

  • High-frequency blood flow-restricted resistance exercise results in acute and prolonged cellular stress more pronounced in type I than in type II fibers
  • 2021
  • Ingår i: Journal of Applied Physiology. - Rockville : American Physiological Society. - 8750-7587 .- 1522-1601. ; 131:2, s. 643-660
  • Tidskriftsartikel (refereegranskat)abstract
    • Myocellular stress with high-frequency blood flow-restricted resistance exercise (BFRRE) was investigated by measures of heat shock protein (HSP) responses, glycogen content, and inflammatory markers. Thirteen participants [age: 24 +/- 2 yr (means +/- SD), 9 males] completed two 5-day blocks of seven BFRRE sessions, separated by 10 days. Four sets of unilateral knee extensions to failure at 20% of one-repetition maximum (1RM) were performed. Muscle samples obtained before, 1 h after the first session in the first and second block (acute 1 and acute 2), after three sessions (day 4), during the "rest week," and at 3 (post 3) and 10 days postintervention (post 10) were analyzed for HSP70, alpha beta-crystallin, glycogen [periodic acid-Schiff (PAS) staining], mRNAs, miRNAs, and CD68(+) (macrophages) and CD661D(+) (neutrophils) cell numbers. alpha beta-crystallin translocated from the cytosolic to the cytoskeletal fraction after acute 1 and acute 2 (P < 0.05) and immunostaining revealed larger responses in type I than in type II fibers (acute 1, 225 +/- 184% vs. 92 +/- 81%, respectively, P = 0.001). HSP70 was increased in the cytoskeletal fraction at day 4 and post 3, and immunostaining intensities were more elevated in type I than in type II fibers at day 4 (206 +/- 84% vs. 72 +/- 112%, respectively, P <0.001), during the rest week (98 +/- 66% vs. 42 +/- 79%, P < 0.001), and at post 3 (115 +/- 82% vs. 28 +/- 78%, P = 0.003). Glycogen content was reduced in both fiber types, but most pronounced in type I, which did not recover until the rest week (-15% to 29%, P <= 0.001). Intramuscular macrophage numbers were increased by similar to 65% postintervention, but no changes were observed in muscle neutrophils. We conclude that high-frequency BFRRE with sets performed till failure stresses both fiber types, with type I fibers being most affected. NEW & NOTEWORTHY BFRRE has been reported to preferentially stress type I muscle fibers, as evidenced by HSP responses. We extend these findings by showing that the HSP responses occur in both fiber types but more so in type I fibers and that they can still be induced after a short-term training period. Furthermore, the reductions in glycogen content of type I fibers after strenuous frequent BFRRE in unaccustomed subjects can be prolonged (>= 5 days), probably due to microdamage.

  • Training machine learning models to predict 30-day mortality in patients discharged from the emergency department: A retrospective, population-based registry study
  • 2019
  • Ingår i: BMJ Open. - London : BMJ. - 2044-6055. ; 9
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives The aim of this work was to train machine learning models to identify patients at end of life with clinically meaningful diagnostic accuracy, using 30-day mortality in patients discharged from the emergency department (ED) as a proxy. Design Retrospective, population-based registry study. Setting Swedish health services. Primary and secondary outcome measures All cause 30-day mortality. Methods Electronic health records (EHRs) and administrative data were used to train six supervised machine learning models to predict all-cause mortality within 30 days in patients discharged from EDs in southern Sweden, Europe. Participants The models were trained using 65 776 ED visits and validated on 55 164 visits from a separate ED to which the models were not exposed during training. Results The outcome occurred in 136 visits (0.21%) in the development set and in 83 visits (0.15%) in the validation set. The model with highest discrimination attained ROC-AUC 0.95 (95% CI 0.93 to 0.96), with sensitivity 0.87 (95% CI 0.80 to 0.93) and specificity 0.86 (0.86 to 0.86) on the validation set. Conclusions Multiple models displayed excellent discrimination on the validation set and outperformed available indexes for short-term mortality prediction interms of ROC-AUC (by indirect comparison). The practical utility of the models increases as the data they were trained on did not require costly de novo collection but were real-world data generated as a by-product of routine care delivery.

  • Entreprenörer som redovisare : bokslutsprocessen i Gasellföretag
  • 2008
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)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.
