  • Accessibility and self-archiving of conference articles : A study on a selection of Swedish institutional repositories
  • 2011
  • Ingår i: Information Services and Use. - Guimarães : IOS Press. - 0167-5265 .- 1875-8789. ; 31:3-4, s. 259-269, s. 123-
  • Tidskriftsartikel (refereegranskat)abstract
    • The main purpose of this project has been to examine the accessibility of refereed conference articles and the OA- and publishing policies of conferences in order to in this way elucidate different aspects concerning self-archiving in Swedish institutional repositories. For this purpose, the project participants have examined a number of conferences and references to conference articles via their institutional repositories during a specific time period and described these from the perspective of a common scheme. The study has showed that the local institutional repositories fill an important role to make conference publications visible. We have found that ca. 50% of the conference papers can be published as postprints in our institutional repositories. We have noticed that ca. 15% or the studied conference articles are not available at all. It is, therefore, of great importance to use local institutional repositories as a publishing channel, not only for primary published material such as dissertations and reports, but also as a source for finding these conference articles "without a home". Between 20-25% of the examined articles were found in some type of OA archive; ca. half of these were found in one of the project participants' own institutional repositories. This indicates that the publishing database of respective higher education institution is an important factor for open accessibility. Ca. 10% of the conferences in the study had an explicit OA policy or expressed such a policy by openly making conference articles accessible on their conference sites. A big problem when it comes to self-archiving of conference articles is the lack of information about OA policy. The landscape of conference publishing is complex and the self-archiving of documents from conferences is very time-consuming. Above all, we would wish a policy resource for conferences similar to the SHERPA/RoMEO. At present, however, there is no other alternative than scrutinizing the conferences' copyright information to the authors and from this attempt to draw conclusions about possible self-archiving. To facilitate the future handling and classification of conference articles in Swedish institutional repositories a number of recommendations are suggested.

  • Verksamhetsförlagd utbildning på avancerad nivå : ny utmaning för specialistutbildningar för sjuksköterskor
  • 2009
  • Ingår i: Vård i Norden. - København : Sjuksköterskornas samarbete i Norden. - 0107-4083 .- 1890-4238. ; 29:94, s. 41-43
  • Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
    • The aim of this article is to discuss challenges in the development of Specialist Nursing Educations as a result of the 2007 Swedish Higher EducationReform: the implementation of the so-called Bologna process. Certain challenges follow this reform, particularly since the specialist nursingprogrammes will be part of the second cycle of the higher education system, and it will be possible to combine the professional degree witha masters degree (one year). Possible strategies in four areas related to the Specialist Nursing Education are discussed: integration of researchbasedknowledge, experienced-based knowledge, improvement knowledge, and strategies for collaboration between university institutions andclinics. Specific didactical issues are raised.

  • Students’ learning as the focus for shared involvement between universities and clinical practice : a didactic model for postgraduate degree projects
  • 2012
  • Ingår i: Advances in Health Sciences Education. - Dordrecht : Springer Netherlands. - 1382-4996 .- 1573-1677. ; 17:4, s. 471-487
  • Tidskriftsartikel (refereegranskat)abstract
    • In an academic programme, completion of a postgraduate degree project could be a significant means of promoting student learning in evidence- and experience-based practice. In specialist nursing education, which through the European Bologna process would be raised to the master’s level, there is no tradition of including a postgraduate degree project. The aim was to develop a didactic model for specialist nursing students’ postgraduate degree projects within the second cycle of higher education (master’s level) and with a specific focus on nurturing shared involvement between universities and healthcare settings. This study embodies a participatory action research and theory-generating design founded on empirically practical try-outs. The 3-year project included five Swedish universities and related healthcare settings. A series of activities was performed and a number of data sources secured. Constant comparative analysis was applied. A didactic model is proposed for postgraduate degree projects in specialist nursing education aimed at nurturing shared involvement between universities and healthcare settings. The focus of the model is student learning in order to prepare the students for participation as specialist nurses in clinical knowledge development. The model is developed for the specialist nursing education, but it is general and could be applicable to various education programmes. © 2011 Springer Science+Business Media B.V.

  • Particle physics at the European Spallation Source
  • 2023
  • Ingår i: Physics reports. - : Elsevier. - 0370-1573 .- 1873-6270. ; 1023, s. 1-84
  • Forskningsöversikt (refereegranskat)abstract
    • Presently under construction in Lund, Sweden, the European Spallation Source (ESS) will be the world’s brightest neutron source. As such, it has the potential for a particle physics program with a unique reach and which is complementary to that available at other facilities. This paper describes proposed particle physics activities for the ESS. These encompass the exploitation of both the neutrons and neutrinos produced at the ESS for high precision (sensitivity) measurements (searches).

  • Technological development for sustainability : The role of network management in the innovation policy mix
  • 2019
  • Ingår i: Technological forecasting & social change. - : Elsevier. - 0040-1625 .- 1873-5509. ; 138, s. 309-323
  • Tidskriftsartikel (refereegranskat)abstract
    • Despite the key role of actor networks in progressing new sustainable technologies, there is a shortage of conceptual knowledge on how policy can help strengthen collaborative practices in such networks. The objective of this paper is to analyze the roles of such policies – so-called network management – throughout the entire technological development processes. The analysis draws on the public management and sustainability transitions literatures, and discusses how various network characteristics could affect the development of sustainable technologies, including how different categories of network management strategies could be deployed to influence actor collaborations. The paper's main contribution is an analytical framework that addresses the changing roles of network management at the interface between various phases of the technological development process, illustrated with the empirical case of advanced biorefinery technology development in Sweden. Furthermore, the analysis also addresses some challenges that policy makers are likely to encounter when pursuing network management strategies, and identifies a number of negative consequences of ignoring such instruments in the innovation policy mix. The latter include inefficient actor role-taking, the emergence of small, ineffective and competing actor networks in similar technological fields, and a shortage of interpretative knowledge.

  • Exploring Quality Challenges and the Validity of Excellence Models
  • 2016
  • Ingår i: International Journal of Operations & Production Management. - 0144-3577 .- 1758-6593. ; 36:10, s. 1201-1221
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: The purpose is to identify and explore important quality-related challenges facing organizations, and how current excellence models incorporate these challenges.Methodology: The article is based on a Delphi study in Swedish organizations, 49 challenges were generated and ranked according to importance. The top 10 ranked challenges were compared to the principles of four excellence models.Findings: The excellence models seem to still be relevant since their content matches many of the challenges identified. The MBNQA and the SIQ models were found to have the most comprehensive coverage, while the ISO model had limited coverage.Research Limitations/Implications: Three areas for further research were identified: 1) how QM can evolve in different contexts with varying needs in terms of adaptive and explorative capabilities, 2) the interfaces of QM and sustainability, and ways to understand how customers and stakeholders can be active contributors to improvements and 3) the roles of the owners and board of directors in QM, and how to organize and distribute responsibilities of the QM work.Practical and Social Implications: Three important challenges could be addressed in upcoming revisions of excellence models: 1) making QM a strategic issue for company owners; 2) involving customers in the improvement activities; and 3) developing processes that are robust, while still easily adaptable.Originality/Value: The Delphi study has identified upcoming challenges in the QM area based on input from 188 quality professionals.

  • Machining of additively manufactured alloy 718 in as-built and heat-treated condition: surface integrity and cutting tool wear
  • 2024
  • Ingår i: The International Journal of Advanced Manufacturing Technology. - : Springer Nature. - 0268-3768 .- 1433-3015. ; 130:3-4, s. 1823-1842
  • Tidskriftsartikel (refereegranskat)abstract
    • Additive manufacturing (AM) using powder bed fusion is becoming a mature technology that offers great possibilities and design freedom for manufacturing of near net shape components. However, for many gas turbine and aerospace applications, machining is still required, which motivates further research on the machinability and work piece integrity of additive-manufactured superalloys. In this work, turning tests have been performed on components made with both Powder Bed Fusion for Laser Beam (PBF-LB) and Electron Beam (PBF-EB) in as-built and heat-treated conditions. The two AM processes and the respective heat-treatments have generated different microstructural features that have a great impact on both the tool wear and the work piece surface integrity. The results show that the PBF-EB components have relatively lower geometrical accuracy, a rough surface topography, a coarse microstructure with hard precipitates and low residual stresses after printing. Turning of the PBF-EB material results in high cutting tool wear, which induces moderate tensile surface stresses that are balanced by deep compressive stresses and a superficial deformed surface that is greater for the heat-treated material. In comparison, the PBF-LB components have a higher geometrical accuracy, a relatively smooth topography and a fine microstructure, but with high tensile stresses after printing. Machining of PBF-LB material resulted in higher tool wear for the heat-treated material, increase of 49%, and significantly higher tensile surface stresses followed by shallower compressive stresses below the surface compared to the PBF-EB materials, but with no superficially deformed surface. It is further observed an 87% higher tool wear for PBF-EB in as-built condition and 43% in the heat-treated condition compared to the PBF-LB material. These results show that the selection of cutting tools and cutting settings are critical, which requires the development of suitable machining parameters that are designed for the microstructure of the material.
