    Design and development of a climatic wind tunnel for physiological sports experimentation2019In: Proceedings of the Institution of Mechanical Engineers, Part P: Journal of Sports Engineering and Technology, ISSN 1754-3371, Vol. 233, no 1, p. 86-100Article in journal (Refereed)
    Abstract [en]

    The aim of this project was to develop a wind tunnel that enables the study of human performance during various types ofsports and physical activities by examining the influence of aerodynamic drag, precipitation, frictional forces and gravitationalforces on uphill and downhill travel on a moving substrate. An overall design for a wind tunnel and working section containinga large treadmill was drafted, followed by computational fluid dynamics simulations of flow conditions to assess thedesign’s feasibility and select from different geometries prior to its construction. The flow conditions in the completed windtunnel were validated using different flows, speeds and treadmill inclinations. Pilot experiments were carried out using across-country skier to investigate the effect of aerodynamic drag on oxygen uptake during double poling and the maximalachieved speed when rolling on a declined treadmill. The purpose was to validate the usefulness of the tunnel. The resultsshowed that flow conditions are acceptable for experiments even in worst-case scenarios with maximal inclined and declinedtreadmill. Results also showed that aerodynamic drag has a significant impact on the skier’s energy expenditure.

    The effect of speed and gradient on running economy and oxygen uptake during downhill running2019Conference paper (Refereed)
    Abstract [en]

    Downhill running poses challenges were the gradient is of importance for energy cost and oxygen uptake. While demonstrated that downhill running at a slight gradient is most efficient, the energy cost increases with a steeper gradient (1). However, the additional effect of running speed has not been studied for downhill running. Therefore, the aim of the study was to analyse the combined effect of gradient and speed in downhill running on oxygen cost and running economy. METHODS:Runners (n=6) were recruited for the study and performed 1) VO2max and running economy (J·kg-1·m-1) tests and 2) an experimental running protocol at two speeds,12 km·h-1 and 80% of the speed at VO2max (V80) and three gradients (0, -5° and -10°). V80 was higher than 12 km·h-1 for all participants. All testing was performed on a large treadmill 3x5 m (Rodby, Sweden) that were controlled for speed and gradient. The experimental protocol was performed continuously with 5 min at each workload in a randomized order, 30 min in total. VO2 was measured throughout the experimental protocol using a mixing chamber (Moxus Metabolic Cart, USA). RESULTS:VO2 expressed as ml·kg-1·min-1 increased because of speed (F1,5=27.8, p=0.003) and decreased with gradient (F1,5=87.6, p<0.001). Between -5° and -10°, VO2 decreased less during V80 compared to 12 km·h-1 shown by an interaction (F2,10=7.9, p=0.009). However, speed did not influence running economy (F1,5=0.9, p=0.38) while gradient increased running economy (F1,5=90.1, p<0.001). A non-significant interaction effect suggests a shift in running economy between -5° and -10° depending on speed (F2,10=3.5, p=0.07). The running economy at V80 was higher compared to 12 km·h-1 at -5° but reversed at -10°. While a relation between running economy at V80 -10°, V80 -5° and 12 km·h-1 -10° (rs>0.88, p<0.019) was found, no relations between running economy on level terrain and steep downhill running (-10°) were recognised. CONCLUSION:While we found no effect on running economy from speed alone, we did see a shift in the running economy for different speeds at an increased downhill gradient. This indicates that a high speed (V80) is more efficient at moderate downhill gradients, while a lower speed (12 km·h-1) is more efficient in steeper downhill gradients. While previous research demonstrate that gradient is of great influence to running economy, the findings of this study suggest that speed also affects the running economy in downhill running.

    Additive Manufacturing of a Cold-Work Tool Steel using Electron Beam Melting2019In: Steel Research International, ISSN 1611-3683, E-ISSN 1869-344X, p. 1-6, article id 1900448Article in journal (Refereed)
    Abstract [en]

    Metal additive manufacturing (AM) is on its way to industrialization. One of the most promising techniques within this field, electron beam melting (EBM), is nowadays used mostly for the fabrication of high‐performance Ti‐based alloy components for the aerospace and medical industry. Among the industrial applications envisioned for the future of EBM, the fabrication of high carbon steels for the tooling industry is of great interest. In this context, the process windows for dense and crack‐free specimens for a highly alloyed (Cr–Mo–V) cold‐work steel powder are presented in this article. High‐solidification rates during EBM processing lead to very fine and homogeneous microstructures. The influence of process parameters on the resulting microstructure and the chemical composition is investigated. In addition, preliminary results show very promising mechanical properties regarding the as‐built and heat‐treated microstructure of the obtained material.

    Health-related quality management values: comparing manager and co-worker perceptions2019In: International Journal of Quality and Service Sciences, ISSN 1756-669X, E-ISSN 1756-6703, Vol. 11, no 4, p. 588-603Article in journal (Refereed)
    Abstract [en]

    Purpose – The purpose of this paper was to modify an existing survey that measures co-worker perceptions of health-related quality management (QM) values and perceived health and to measure both co-worker and manager perceptions of those values. The purpose was also to test the modified survey and then compare theresults from managers and co-workers from two organizations in which the survey has been used to measure baseline data in a lean research project and to help managers understand the areas where improvement isneeded. Design/methodology/approach – An earlier survey measuring co-worker perception of the dimensions of the health-related QM values “leadership commitment” and “participation of everybody” has been developed with corresponding statements for managers. The results of the survey were analyzed using SPSS(Statistical Package for the Social Sciences), the Cronbach’s alpha coefficient was calculated for each of thedimensions, and the correlations between the dimensions and the health index were investigated using the Pearson correlation. The mean and standard deviation were also calculated. Findings – The modified survey is presented in the paper, and the results demonstrate that the managers’ perception of the presence of health-related QM values is higher than that of the co-workers. Seeing the leadership from the co-workers’ standpoint compared with the managers’ perspective provides novel insight for both the researcher and the managers. Originality/value – Leaders in organizations must develop greater efficiency to improve operational performance and develop healthy work environments. Practicing QM can benefit performance and is central for inspiring quality and efficiency within organizations, as well as for enhancing co-worker well-being. Earlier research found relationships between co-workers’ perception of their health and the health-related QMvalues “leadership commitment” and “participation of everybody.” With the survey presented in this paper, it is possible to measure these health-related QM values and provide a comparison between manager and coworker perceptions.

    Text Mining The Quality Paradigm(s)2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The purpose of this thesis orbits around an examination of the formation of a quality paradigm. In this inquiry, the exploration and application of text mining have been used to provide new insights into quality as a paradigm.

    The findings reveal the existence of unifying topics, around which research on quality has clustered, constituting the foundational pillars of an academic quality paradigm. These foundational pillars are operational paradigms that embody both epistemological perspectives and operational concerns regarding quality. The three operative paradigms upon which the quality paradigm rests are the operative paradigm of back-end quality (orbiting around: QM, TQM and service quality), the operative paradigm of middle-way quality (orbiting around: ISO, BEMs and Quality Awards) and the operative paradigm of front-end quality (orbiting around: Reliability, Costs and Processes). The three operative paradigms differ in their levels of abstraction, accountability and system-learning emphasis. However, the mutual purpose and aim of the three operative paradigms, and hence the paradigm as a whole, is to continuously control, assure and develop systems affecting quality initiatives in service of the customer(s).

    The findings also indicate that the operative paradigms of back-end and front-end quality seem to be specializing and drifting apart, which might lead to a division of the quality paradigm into two separate paradigms.

    The studies in this thesis also confirm the existence of changes in the focus and popularity of specific topics. However, the key epistemological findings are the central and perpetual research topics that are identified – supporting the supposition that research on quality truly constitutes a delimited and recognized research paradigm.

    Furthermore, the studies show that research on quality expanded during the end of the 1980s and beginning of the 1990s, after which a contraction took place, followed by stability at the start of the 21st century. Consequently, it is found that research on quality entered a stable and mature phase in the 21st century, settling down as a distinctive and established research paradigm.

    Finally, it is found that the exploration and application of text mining is a potent approach when probing the epistemological foundations of an academic discipline.

    The quality movements three operational paradigms - A text mining venture2020In: The TQM Journal, ISSN 1754-2731, E-ISSN 1754-274XArticle in journal (Refereed)
    Abstract [en]

    Purpose: This study aims to analyze four text-mining studies of quality management (QM) to illustrate and problematize how the research on quality has informed the quality paradigm since the 1980s. By understanding history, one can better manage current developments. Design/methodology/approach: The findings are based on a meta-analysis of four text-mining studies that explore and describe 11,579 research entries on quality between 1980 and 2017. Findings: The findings show that the research on quality during the past 30 years form a research paradigm consisting of three operational paradigms: an operative paradigm of backend quality orbiting around QM, total QM (TQM) and service quality; an operative paradigm of middle-way quality, circling around the International Organization for Standardization (ISO), business excellence frameworks (BEFs) and quality awards; and an operative paradigm of frontend quality, revolving around reliability, costs and processes. The operative paradigms are interconnected and complementary; they also show a divide between a general management view of quality and a hands-on engineering view of quality. The findings indicate that the research on quality is a long-lived standalone paradigm, supporting the notion of quality being a genuine academic entity, not a fashion or fad. Research limitations/implications: The empirical basis of the study is four text-mining studies. Consequently, the results and findings are based on a limited number of findings. Originality: Text-mining studies targeting research on quality are scarce, and there seem to be no prior models that depict the quality paradigm based on such studies. The perspectives presented here will advance the existing paradigmatic discourse. The new viewpoints aim to facilitate and deepen the discussion on current and future directions of the paradigm.

    Four decades of research on quality: summarising, Trendspotting and looking ahead2019In: Total quality management and business excellence (Online), ISSN 1478-3363, E-ISSN 1478-3371Article in journal (Refereed)
    Abstract [en]

    The purpose of this paper is to identify and depict the key areas around which research on quality has orbited during the past 37 years. Additionally, this paper aims to explore longitudinal patterns and trends in the identified key areas. Thereby, this study aims to present new perspectives on the foundational elements and evolutionary patterns of research on quality as well as future directions. The paper applies data- and text modelling methodology to a chronological dataset covering 37 years and consisting of scientific journals specialising in research on quality; it also includes scientific journals with a broader spectrum of operations management (OM) research. The study identifies seven central topics around which research on quality has centred during this time period: Service Quality & Customer Satisfaction; Process design & Control; ISO Certification & Standards; TQM - Implementation, Performance & Culture; QM - Practices & Performance; Reliability, Costs, Failure & Problems and Excellence - BEMs, Quality Awards & Excellence in Higher Education. The results also show that the total number of entries has risen constantly since 1980; however, there was a period of decline between 2000 and 2012, indicating that after almost four decades, research on quality is still vibrant and relevant.

    Processorienterad kultur: Mätmetod över beteenden som driver resultat i en processorienterad kultur2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The authors of this thesis got the idea to this projekt from a lecture and from Drucker´s quote “Culture eats strategy for breakfast”. The purpose was to investigate what behaviours that drives results in a process oriented culture, and to develop a model for measuring these behaviours.

     

    The goal was to measure the behaviours in the organisation and to help them obtain a culture that exceed the culture of their competitors, and reaching process orientation using a quantitative survey in a pilot study. Even though we got answers from all participants in the survey, the population was too small to generate statistically significant results. The study is based on the theory of four clusters; “fumblers”, “talkers”, “organisers”, and “mappers” by Eriksson and Hellström (2013) and the results are displayed in diagrams and an IPA-matrix.

     

    The conclusion is that the organisation leans towards function orientation, but they are striving towards becoming process orientated. The total picture the authors got is they belong to the cluster “talkers” with a slight margin. They are heading in the direction of becoming process orientated by focusing on their communication though. The model was designed using research about what behaviours have a positive or a negative effect on the processorientated culture of the organisation. The weakness of the model is that it only takes the cornerstone “working with processes” into account and does not measure the other perspectives of quality culture.

    Surface modification of Ti6Al4V alloy scaffolds manufactured by electron beam melting2019In: / [ed] Godymchuk A.,Rieznichenko L.,Semenov M., Institute of Physics Publishing (IOPP), 2019, no 1Conference paper (Refereed)
    Abstract [en]

    In this paper, the results of the surface functionalization of the Ti6Al4V alloy scaffolds with different structures for use as a material for medical implants are presented. Radio frequency magnetron sputtering was used to modify the surface of the porous structures by deposition of the biocompatible hydroxyapatite (HA) coating with the thickness of 86050 nm. The surface morphology, elemental and phase composition of the HA-coated scaffolds were studied. According to energy-dispersive X-ray spectroscopy, the stoichiometric ratio of Ca/P for flat, orthorhombic and cubic scaffolds is 1.65, 1.60, 1.53, respectively, which is close to that of stoichiometric ratio for HA (Ca/P = 1.67). It was revealed that this method of deposition makes it possible to obtain the homogeneous crystalline coating both on the dense sample and in the case of scaffolds of complex geometry with different lattice cell structure.

    Determination of the properties and loading efficiency of encapsulated BSA-FITC and dexamethasone for drug delivery systems2019In: IOP Conference Series: Materials Science and Engineering, Institute of Physics Publishing (IOPP), 2019, Vol. 597, no 1, article id 012056Conference paper (Refereed)
    Abstract [en]

    In this work porous microparticles of calcium carbonate were synthesized with bovine serum albumin - fluorescein isothiocyanate conjugate (BSA-FITC) and dexamethasone, and then used for encapsulation in polymer microcapsules by means of layer-by-layer assembly (LbL). The properties of the obtained microcapsules were characterized by scanning electron microscopy, dynamic light scattering, infrared-, ultraviolet- and visible spectroscopy. According to the performed DLS measurements, an average hydrodynamic diameter ranged from 4 to 8 m and zeta-potential for all types of capsules was determined as -18 and -21 mV. BSA-FITC was encapsulated using this approach yielded a loading efficiency of 49 % protein. This value calculated for dexamethasone was of 38%. The microcapsules filled with an encapsulated drug may find applications in the field of biotechnology, biochemistry, and medicine.

    Adhesion, proliferation, and osteogenic differentiation of human mesenchymal stem cells on additively manufactured Ti6Al4V alloy scaffolds modified with calcium phosphate nanoparticles2019In: Colloids and Surfaces B: Biointerfaces, ISSN 0927-7765, E-ISSN 1873-4367, Vol. 176, p. 130-139Article in journal (Refereed)
    Abstract [en]

    In the present study, biocomposites based on 3D porous additively manufactured Ti6Al4V (Ti64) scaffolds modified with biocompatible calcium phosphate nanoparticles (CaPNPs) were investigated. Ti64 scaffolds were manufactured via electron beam melting technology using an Arcam machine. Electrophoretic deposition was used to modify the scaffolds with CaPNPs, which were synthesized by precipitation in the presence of polyethyleneimine (PEI). Dynamic light scattering revealed that the CaP/PEI nanoparticles had an average size of 46 ± 18 nm and a zeta potential of +22 ± 9 mV. Scanning electron microscopy (SEM) revealed that the obtained spherical CaPNPs had an average diameter of approximately 90 nm. The titanium-based scaffolds coated with CaPNPs exhibited improved hydrophilic surface properties, with a water contact angle below 5°. Cultivation of human mesenchymal stem cells (hMSCs) on the CaPNPs-coated Ti64 scaffolds indicated that the improved hydrophilicity was beneficial for the attachment and growth of cells in vitro. The Ti6Al4V/CaPNPs scaffold supported an increase in the alkaline phosphatase (ALP) activity of cells. In addition to the favourable cell proliferation and differentiation, Ti6Al4V/CaPNPs scaffolds displayed increased mineralization compared to non-coated Ti6Al4V scaffolds. Thus, the developed composite 3D scaffolds of Ti6Al4V functionalized with CaPNPs are promising materials for different applications related to bone repair.

    Abstract [en]

    In recent decades, sustainability has become increasingly important at all levels ofsociety. Today's customers and stakeholders require organizations to includesustainability in their processes to a greater extent than before. System view of anorganization and focus on continuous improvement are central to both sustainabledevelopment and quality development, but synergy effects between them are arelatively new area of research. Business evaluation according to an excellency modelwhere both perspectives are integrated is a way of trying to achieve success. Throughcase study of an award recipient's quality development journey, answers were soughtby using semi-structured interviews in combination with document analysis on howquality development can support organizations to change towards a more sustainabledevelopment. The results show that the focus on culture and structure in anorganization and soft values is a way to go to achieve synergy effects between qualitydevelopment and sustainable development. There are great opportunities for anorganization that has well-established systematic working methods for qualitydevelopment to also apply the working methods for sustainable development and thuscontribute to meeting Agenda 2030.

    Abstract [en]

    Total Quality management in   cooperation with work of change in organisations has got a lot of attention   today due to that it has remarkable influence on different companies   productivity and competitiveness in a world that is dependent on   globalisation. The aim of this paper is to explore how a large public   organisation has applied participation among the coworkers during a change of   work in the organisation. The main goal of the change is to form a new unit   with a new leader for this unit. The study is a qualitative case study were   both coworkers and the leader of the unit has been interviewed. Material that   was used in connection with the change in the organisation has been applied   with the purpose to triangulate the study and make the credibility of the   study stronger. The interviews that was made was transcribed and analyzed   with the help of charts for a better understanding. The analyze resulted in   several different categories witch the coworkers highlighted as important in   this specific change of the organisation. The result shows that both the   coworkers and the new leader in the unit believes that participation in   connection with change is of importance and that they are working active to   create participation. The coworkers centralizes their own role and a good   leader as successfactors for a successful change. Important factors in the   change are being a part of the decision, structured ways to create   participation throughout the whole change, extended information and a   trustworthy leader.

    Abstract [en]

    Committed leadership is the foundation for creating a good quality culture andto succeed, the participation of employees is required. Researchers argue thatsupport for the current leaders in healthcare has until now been ratherundeveloped. The purpose of this study was to understand how the qualityculture in Swedish healthcare can be linked to the leaders' ability to promotegood co-workership. This study was based on an explanatory sequentialmixed method with two quantitative measurements that ultimately resulted in aqualitative interview. A measurement of the quality culture at Swedishhospitals was taken based on a previously developed instrument formeasuring quality culture . The measuring instrument comprises 13behavioral pairs that promote or hinder a quality culture. This measure showsthat there is generally a good quality culture at Swedish hospitals at present.Through this measurement, a regression analysis was done which links to thehospital's results in the National Patient Survey. A statistically significantbehavior was observed, and according to this measurement, is likely to createmore satisfied patients as more professions feel that this behavior occurs intheir organization. The behaviour in question can be described as: when wehave a problem, we find out the root cause before we decide on a solution.This behavior was brought into two successful hospitals in order to understandmore deeply how they work with the co-workership in this particular behavior.Based on the workshop with these two hospitals, we conclude that leadersneed to have experienced the quality culture and the co-workership they areassumed to carry in order to promote an employee culture that is linked to thequality culture. In pursuit of success, a strong quality culture is desirable, butbased on the workshops, the authors see no possible quick solution to reachit. The result shows that today's leaders in healthcare need support in the formof a mentor or time for reflection on leadership on their own or in groups inorder to develop. In constructive approach, it is with improvement knowledgethat everyone's involvement in the work of continuous improvement isconducted. This requires reflection, honesty, courage, openness and trustfrom everyone involved and intentions rooted in the wellness and prosperity ofall.

    Abstract [en]

    Making   Quality Management a management issue has been addressed as one of the   biggest organizational challenges by managers and leaders. TQM is an accepted model that is based on values, working methods and   tools, which are crucial for succesful quality and business development. In   TQM, various models such as ISO 9001 and SIQ Management model can deploy   quality management. This study focuses on the SIQ Management   model, which is an excellence model. The purpose of this study has been to   increase the understanding of how management can work with quality   management. The study was conducted at Bostads AB Mimer, which in 2018   received Recognition for succesful business development from SIQ. The study   was conducted as a qualitative study where eleven leaders were interviewed   with semi-structured questionnaires. Documents and written information from   the company has also been analyzed. The result shows that a comitted   management benefits the quality management. Mimer has also had an established   core values, four clera goals and a dedicated quality developer. A few   challenges also emerged where quality management was perceived as   time-consuming was one of the factors described to have the most negative   impact on the work.

    Kvalitetsarbete inom högre utbildning: Framtagande av en modell för arbetemed utvecklingsprojekt inom lärarutbildning2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The latest year's review of the higher education institutions' quality systems carried out by theuniversity chancellor's office (UKÄ) shows that even higher education needs to work with itsinternal quality work and that the higher education institutions need to develop working methodsand methods for implementing it. The purpose of this work was to contribute with knowledgeabout how work with quality development looks within higher education and to develop a modelfor working with improvement and quality development in teacher education. The authorparticipated in a project work as an interaction researcher to develop a model for the work onimprovement and development work in teacher education. This study has contributed with theknowledge that higher education today works with the quality work based on the guidelines foundin the Higher Education Act, the Higher Education Ordinance and the Standards and Guidelinesfor Quality Assurances in the European Higher Education Area (ESG). The conclusion was thatthe model for working with development projects developed in the project work must follow theselaws, regulations and guidelines stated in the ESG and that the working method in the modelshould be cyclical and can be based on PDSA. Furthermore, the conclusion is that the model canadvantageously be based on offensive quality development and the cornerstone model and that ifthe learning within the organization takes place at all levels continuously, the model can supportthe work of a learning organization. This study may be of interest to others who want to learnmore about interaction research and for higher education institutions that are faced withdeveloping their own internal quality work.

    Complexity Quality Management: Enabling Leadership, Adaptive Space & Metaphors2019Conference paper (Refereed)
    Abstract [en]

    Purpose

    Most organizations experience the complexity and tensions between producing and innovating. In order to adapt to the future, these organizations need enabling leadership that creates adaptive space to facilitate and enable the necessary change process for renewal. This ability is necessary for 21st century TQM, i.e., the Emergence TQM paradigm. Guiding images such as metaphors have been suggested to support transformative change, but have only received limited research. This paper investigates the role of guiding images as a facilitating tool for leading organizational adaptability and contribute to future leadership practices of QM.

    Design/methodology/approach

    The paper studies three cases of organizations that were under pressure from the outside to make decisions about how to innovate. The paper studies the management team at each organization while they tackle tensions and make decisions about what to do while using a generative image to support the leadership process. The researchers gained access to key meetings to study the processes through observations that were later analyzed with the use of storyboards.

    Findings

    The leadership processes of handling organizational adaptability can be facilitated by guiding images. The images can be generated while managers experience tension and can help support the leadership processes of conflicting and connecting. Three types of guiding images were identified.

    Originality/value

    The paper contributes with practical knowledge about how to enabling organizational adaptability by supporting enabling leadership processes. Furthermore, the paper contributes to complex adaptive leadership theory in the context of quality management.

    Exercise in Sub-zero Temperatures and Airway Health: Implications for Athletes With Special Focus on Heat-and-Moisture-Exchanging Breathing Devices2020In: Frontiers in Sports and Active Living, ISSN 2624-9367, Vol. 2, no 34Article in journal (Refereed)
    Abstract [en]

    Asthma is highly prevalent among winter endurance athletes. This “occupational disease” of cross-country skiers, among others, was acknowledged during the 1990s, with the pathogenesis attributed to repeated and prolonged exposure to cold, dry air combined with high rates of ventilation during exercise. Nevertheless, more than 25 years later, the prevalence of asthma among Scandinavian cross-country skiers is unchanged, and prevention remains a primary concern for sports physicians. Heat-and-moisture-exchanging breathing devices (HMEs) prevent exercise-induced bronchoconstriction in subjects with pre-existing disease and may have potential as a preventative intervention for healthy athletes undertaking training and competition in winter endurance sports. Herein we firstly provide an overview of the influence of temperature and humidity on airway health and the implications for athletes training and competing in sub-zero temperatures. We thereafter describe the properties and effects of HMEs, identify gaps in current understanding, and suggest avenues for future research.

    Exploring the Impact of Consumer Attitudes on Reusage and Waste Prevention2019In: 22nd QMOD conference: Conference on Quality and Service Sciences ICQSS 2019, 13-15 October 2019, Krakow, Poland / [ed] Su Mi Dahlgaard-Park & Jens J. Dahlgaard, 2019Conference paper (Other academic)
    Abstract [en]

    Circular economy is a concept whereby organic and extracted materials are used and reused in balanced material loops. As a first step in the concept, effective waste disposal and recycling is proposed, however waste prevention is substantially more effective than waste disposal. This study has investigated current attitudes towards reusing products. The study was conducted at and in the vicinity of a Swedish recycling center.

    The concept of waste threshold has been investigated and suggestions have been made on how to improve the waste value chain by keeping the value of objects as high as possible and allowing for the interchange of second-hand items at the recycling center. In the study the most common obstacle to reusing is stigmatized attitudes towards reusage and the learned behavior ‘We are so used to buying new things…’.

    How to improve the transfer process from intensive care to general wards - listening to the co-workers2019In: Leadership and strategies for Sustainable Quality and Innovation in the 4th Industrial Revolution. Lund, Lund, 2019Conference paper (Refereed)
    Abstract [en]

    Background - Many errors and threats to patient safety are caused by deficiencies in the organization, such as inadequate procedures, inadequate planning and lack of information or communication. A specific danger to patient safety is the various gaps in the continuity of care. An example of the gap is the transfer of patients from the high-tech intensive care environment to the less frequent personnel ward environment, a process called ICU transitional care. ICU-nurses, ward-nurses, physicians, and other healthcare professionals, may provide this care. The effects of a poorly coordinated discharge can lead to readmission to the ICU and avoidable deaths.This study is a part of a research project financed by The Kamprad Family Foundation, with a purpose to gain new knowledge about how efficiency and quality in patient transfers within healthcare care can be improved. The purpose will be achieved through cooperation between the two research subjects Quality Management and Nursing science.Purpose - The purpose of this paper was to gain knowledge about how to improve patient transfers from intensive care to the general ward, by describing the intensive care co-workers generated suggestions.Methodology/approach – Six interdisciplinary focus groups interviews were conducted with co-workers at two hospitals in Sweden. The interviews were taped, verbatim transcribed and analysed with a mixed method. The QM values: ‘customer focus’, ‘leadership commitment’, ‘participation of everybody’, ‘continuous improvement’, ‘process focus’ and ‘base decisions on facts’ were used as an analytic framework.Findings - The co-workers suggested that the process should be defined and structured. The analyses showed a total of 94 suggestions that mainly were focused at following areas; planning, information, and communication, interest in the transfer process, enough resources, standardize and create routines, learning, follow up and evaluate.Practical implications - ICU transitional care is multifaceted and needs a holistic, system thinking solution. The findings indicate that the process could be safer, and more efficient by implementing the co-worker generated suggestions. The suggestions can be used to improve patients’ transfers in many contexts in healthcare, not only ICU transitional care.

    Adapting a Lean leadership-training program within a health care organization through cocreation2020In: International Journal of Quality and Service Sciences, ISSN 1756-669X, E-ISSN 1756-6703, Vol. 12, no 1, p. 15-28Article in journal (Refereed)
    Abstract [en]

    Purpose: The purpose of this paper is to describe and evaluate a Lean leadership-training program within the health-care sector. A training program developed through a cocreative process with the intent of enhancing the possibilities for a context-specific adaption of Lean. Design/methodology/approach: A cocreated leadership-training program, executed over a period of one year, is described both as a model development process and as the final training program. The program was evaluated through reflective discussions and feedback as well as a written final evaluation of the program from participants in the program. Findings: The evaluation shows that the objectives of the training program were met, at least among the participants who attended the whole program. Using a cocreative process when developing and realizing a leadership-training program enhances the possibilities for an organization to adapt Lean to its own context. One condition for this approach to be successful is that the expectations of both the organization and the university need to be in focus through the whole process. In addition, the executive team needs to be continuously engaged and create conditions for the organization to realize the potential benefits of the training program. Originality/value: This paper highlights the challenge when applying Lean in a health-care organization but also describes a way to address Lean training and learning in this context.

    Assessing Quality Management culture in order to develop ICU transitional care2019In: 22nd QMOD conference: Quality and Service Sciences ICQSS 2019 / [ed] Su Mi Dahlgaard-Park, 2019Conference paper (Refereed)
    Abstract [en]

    Purpose - The purpose of this paper is to present and analyse the result from using a questionnaire measuring the presence of a number of QM values, as well as the use of Appreciative Inquiry (AI) and the feeling of pride in a healthcare setting focusing on transitional care.

     

    Methodology/approach – Co-workers at two different hospital’s intensive care units answered a previously developed and tested questionnaire. A new factor was developed in order to measure customer focus in the healthcare context. The result was analysed using SPSS with the aim of finding areas to improve the patient transfer process from intensive care to general ward.

     

    Findings – The questionnaire can be used to create an understanding of the existing culture in an organization but it needs to be analysed qualitatively. The result from the examined organizations show a common culture in the two units even though they are located in different hospitals and cities. The result further shows some differences between professions but overall, the result points at a relatively high agreement to the QM values in the organization indicating the presence of a quality culture.    

     

    Practical implications – Using a QM value survey in the healthcare context could help developing the care from a different point of view then ordinary. It could help to shift focus from individual to group and system.

    Abstract [en]

    The purpose of this study is to examine which factors contribute to increasing the pace ofimprovement work in the case of continuous improvements in an organization. The purpose isalso to examine how to work with this in a active and structured way to ensure long-term survivalfor the organization. A qualitative literature study has been conducted to find factors that cancontribute to increasing the rate of improvement. The result in the form of subfactors has beencompiled and grouped using a affinity diagram. Based on four summary factors, methods,working methods, tools and examples have been developed that show how organizations in aconscious and systematic way can work to increase the rate of improvement in the case ofcontinuous improvements. The conclusion is that the factors that can promote an increased pacein the case of continuous improvements are: proactive work that ensures that the organization'sperformance lives up to strategy, policy and goals and that these are communicated; promote aculture that increases motivation throughout the organization to work with continuousimprovement; secure resources and skills development in the form of knowledge and learningwithin all levels and groups; system of processes and stakeholders, both internal and external, topromote interaction and improvement. There are a number of methods that can be effective inincreasing the rate of improvement.

    Creating a Force of Development in Swedish Healthcare: A Contribution from the First-Line Managers’ Perspective When Driving Improvement Work Based on Lean2019Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis is about the healthcare managers, working at operational levels, defined as the first-line managers. These managers often are given the role and responsibility to integrate improvements into daily work. A stronger development ability of Swedish healthcare requires first-line managers with a developed ability to lead change. Thereby efforts must be made to provide these managers with supportive work conditions when leading and developing organizations. One approach to organizational development is Lean, which refers to a strong improvement culture based upon a supportive and highly engaged leadership as well as a strong customer focus. The purpose of this thesis is to contribute to knowledge about and an understanding of the conditions that influence first-line healthcare managers’ abilities to drive improvement work based on Lean. Some of the conditions investigated are; time, receiving support from the own manager, feeling joy in improvement work and being assured about the effects of Lean.

    The thesis is based on three separate analyses of a web-based survey, which relate to the two research questions. The study was conducted in a Swedish healthcare organization two years after the initiation of Lean. The analyses are presented in three separate papers. The first research question considers; How can an instrument be developed that investigates first-line managers’ views on their role, conditions and ability to drive improvement work based on Lean? The second question is; What can be learned from using the instrument that investigates first-line managers’ views on their role, conditions and ability to drive improvement work based on Lean? A qualitative study based on a hermeneutic, inductive, qualitative research approach was conducted in order to meet the research purpose and answer the research questions.

    The thesis is mainly based on three papers. In paper 1 it is stated that the assuredness about the effects of Lean was quite high among the managers when the survey was conducted, such as that Lean contributes to a greater patient focus and to the development of an improvement culture. In paper 2 it is noted that the first-line managers view their role as crucial in improvement work based on Lean. Time, support from coworkers, and a clear vision and clear goals were the three conditions they considered to be most important for their ability. The results presented in paper 3 show that to initiate improvement work based on Lean, they ask for own managers who are assured about Lean and include them in discussions. They view their role and responsibility in relation to their coworkers as extensive, for instance increating a culture where problems and mistakes are viewed as possibilities to improve and for encouraging that new work procedures are tested. The findings indicate a need for a deeper understanding of Lean. It is concluded that a thorough understanding of Lean is a main condition for the first-line managers´ ability to drive improvement work based on the approach. Developing a common view of Lean takes time, which is important to emphasize in the practical setting to motivate for a long-term perspective. This development takes highly motivated, assured and persistent leaders with a continuous improvement attitude and a mission to improve healthcare together.

    There is also an applied research question; How can the use of the instrument contribute to developing first-line managers’ role, conditions, and ability to drive improvement work based on Lean? In its essence, Lean is concerned with improving a system and since the instrument raises questions about relationships between organizational members, it sets focus on the system and calls on a system view. The responsibility for one management level must continuously be set I relation to another, when putting the pieces together in the “improvement puzzle”. Change depends on adjustments in human behavior and the instrument establishes a focus on the people in the processes necessary for development and results. The instrument also provides opportunity and structure to investigate and talk about the soft conditions important for the ability, such as receiving support from the own manager, and feeling inspiration and being assured. The practice of Lean requires changes in attitudes, new habits, new skills in the whole system, meaning in each individual from the executive management to the front-line workers. Thereby self-reflection becomes important, which requires forums for dialogue. It is concluded that such forums can influence first-line healthcare managers’ abilities to drive improvement work based on Lean. In dialogue forums improvement work can be reflected upon and learned from together.

    Creating a development force in Swedish healthcare: a focus on the first-line managers’ perspective when applying Lean2019In: International Journal of Health Care Quality Assurance, ISSN 0952-6862, E-ISSN 1758-6542, Vol. 32, no 8, p. 1132-1144Article in journal (Refereed)
    Abstract [en]

    Purpose The purpose of this paper is to present the results from a study that investigates first-line healthcare managers' views on their role and the conditions that influence their ability to drive improvement work based on Lean. Design/methodology/approach A questionnaire was sent to all first-line managers in a healthcare organization to investigate their views on their role, conditions and ability to create change according to Lean. The results from four of the questions are presented, which focus on how crucial they consider their role to be for managing improvement work based on Lean, what work tasks their time is spent on, what factors they consider to be important to their ability to drive change and what factors best describe what Lean provides. Findings The results show that first-line managers claim that their role is crucial in improvement work, but when they defined their work tasks, the time spent on improvements was not frequently described. Time, support from coworkers, and a clear vision and clear goals were the three factors that they considered to be most important to their ability to drive improvement work. Considering their leadership, Lean contributed to the structure with tools and supportive methods. Originality/value The questions can be used separately or as part of the entire questionnaire before and along a Lean process to obtain a better understanding of how to create a sustainable Lean approach in healthcare. Understanding the factors that first-line managers consider supporting their ability in improvement work and what they consider Lean provides is important in creating a development force in Swedish healthcare.

    "Stuck in the middle” Healthcare first-line managers´ responsibilities and needs of support when applying Lean2020In: International Journal of Quality and Service Sciences, ISSN 1756-669X, E-ISSN 1756-6703Article in journal (Refereed)
    Abstract [en]

    Purpose - The purpose of this paper is to present the supportive conditions that the first-line health-care managers claim that they need from their own managers and what they experience as their own roles and responsibilities in relation to their coworkers when applying Lean principles and practices.

    Design/methodology/approach - A survey with a Web-based questionnaire was designed and used in a Swedish health-care organization two years after the initiation of Lean to investigate the managers' views on their role, conditions and ability to create change according to Lean. The result from two of the questions will be presented where one focuses on the relationship to the first-line managers' own manager and the second on the relationship to their coworkers.

    Findings - The results show that to initiate improvement, work based on Lean first-line managers ask for own managers who are assured about Lean, include them in discussions and ask for follow-ups and results about Lean. Concerning first-line managers' relation to their coworkers they experience themselves as responsible for leading toward creating a culture where problems and mistakes are viewed as possibilities to improve, for encouraging that new work procedures are tested and for creating commitment and inspiration in relation to their coworkers.

    Originality/value - The questions can be used separately or as part of an entire questionnaire before and along the Lean process to highlight organizational issues such as shared responsibility and supportive relations when developing health care.

    Powder-bed additive manufacturing for aerospace application: Techniques, metallic and metal/ceramic composite materials and trends2019In: MANUFACTURING REVIEW, ISSN 2265-4224, Vol. 6, article id 5Article, review/survey (Refereed)
    Abstract [en]

    The current paper is devoted to classification of powder-bed additive manufacturing (PB-AM) techniques and description of specific features, advantages and limitation of different PB-AM techniques in aerospace applications. The common principle of "powder-bed" means that the used feedstock material is a powder, which forms "bed-like" platform of homogeneous layer that is fused according to cross-section of the manufactured object. After that, a new powder layer is distributed with the same thickness and the "printing" process continues. This approach is used in selective laser sintering/melting process, electron beam melting, and binder jetting printing. Additionally, relevant issues related to powder raw materials (metals, ceramics, multi-material composites, etc.) and their impact on the properties of as-manufactured components are discussed. Special attention is paid to discussion on additive manufacturing (AM) of aerospace critical parts made of Titanium alloys, Nickel-based superalloys, metal matrix composites (MMCs), ceramic matrix composites (CMCs) and high entropy alloys. Additional discussion is related to the quality control of the PB-AM materials, and to the prospects of new approaches in material development for PB-AM aiming at aerospace applications.

    The impact of post manufacturing treatment of functionally graded Ti6Al4V scaffolds on their surface morphology and mechanical strength2020In: Journal of Materials Research and Technology, ISSN 2238-7854, Vol. 9, no 2, p. 1866-1881Article in journal (Refereed)
    Abstract [en]

    An ultrasonic vibration post-treatment procedure was suggested for additively manufactured lattices. The aim of the present research was to investigate mechanical properties and the differences in mechanical behavior and fracture modes of Ti6Al4V scaffolds treated with traditional powder recovery system (PRS) and ultrasound vibration (USV). Scanning electron microscopy (SEM) was used to investigate the strut surface and the fracture surface morphology. X-ray computed tomography (CT) was employed to evaluate the inner structure, strut dimensions, pore size, as well as the surface morphology of additively manufactured porous scaffolds. Uniaxial compression tests were conducted to obtain elastic modulus, compressive ultimate strength and yield stress. Finite element analysis was performed for a body-centered cubic (BCC) element-based model and for CT-based reconstruction data, as well as for a two-zone scaffold model to evaluate stress distribution during elastic deformation. The scaffold with PRS post treatment displayed ductile behavior, while USV treated scaffold displayed fragile behavior. Double barrel formation of PRS treated scaffold was observed during deformation. Finite element analysis for the CT-based reconstruction revealed the strong impact of surface morphology on the stress distribution in comparison with BCC cell model because of partially molten metal particles on the surface of struts, which usually remain unstressed.

    X-ray computed tomography of multiple-layered scaffolds with controlled gradient cell lattice structures fabricated via additive manufacturing2019Conference paper (Refereed)
    Abstract [en]

    In this paper we report on the characterization by X-ray computed tomography of calcium phosphate (CaP) and polycaprolactone (PCL) coatings on Ti-6Al-4V alloy scaffolds used as a material for medical implants. The cylindrical scaffold has greater porosity of the inner part than the external part, thus, mimicking trabecular and cortical bone, respectively. The prismatic scaffolds have uniform porosity. Surface of the scaffolds was modified with calcium phosphate (CaP) and polycaprolactone (PCL) by dip-coating to improve biocompatibility and mechanical properties. Computed tomography performed with X-ray and synchrotron radiation revealed the defects of structure and morphology of CaP and PCL coatings showing small platelet-like and spider-web-like structures, respectively.

    Microstructure investigation of Ti-26Nb alloy manufactured from elemental powders by electron beam melting2019In: Journal of Physics, Conference Series, ISSN 1742-6588, E-ISSN 1742-6596, no 1, article id 012126Article in journal (Refereed)
    Abstract [en]

    Alloys which are planned to be used for implants fabrication must possess excellent biocompatibility, high strength, and low Young's modulus. A low elastic modulus, close to that of the cortical bone could significantly reduce the stress-shielding phenomenon usually occurring after surgery. Beta-titanium alloys such as Ti-Nb are good candidates for this purpose. Nb is known as a biocompatible metal used for titanium β-phase stabilization. Previous investigations indicate that the increase of Nb content results in the increase of β phase amount but the decrease of β grain size. In this study, we were aiming at the investigation of the microstructural properties of a titanium alloy manufactured by electron beam melting from the elemental powders mixture of Ti and Nb with 26 at.% of Nb. The influence of operating parameters on the efficacy of dissolving Nb particles in Ti was studied. The results obtained by SEM analysis demonstrated that electron beam energy has a significant effect on the homogeneity of the manufactured specimens. To obtain homogeneous and porosity-free specimens high energy level is required. The microstructure of these specimens was characterized. © Published under licence by IOP Publishing Ltd.

    Electron beam melting: Impact of part surface properties on metal fatigue and bone ingrowth2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Abstract

    The aim of this thesis is to investigate aspects on how additive manufacturing (AM) contributes to functional bone implants with the use of the electron beam melting (EBM) technology. AM manufactures parts according to computer-aided design, and the EBM technology melts powder using an electron beam, which acts similar to a laser beam. The topics discussed in this thesis are related to surface roughness that originate from the melted metal powder, and the thesis tries to define some aspects that affect implant functionality. Process parameters steering the electron beam and biocompatibility arising from the surface texture were the initial parts of the PhD studies, and the other half focused on post-processing and fatigue, which are important for medical and industrial applications. There are six studies in this compilation thesis. They are abbreviated as P - process parameters, M - medical applications, and F - fatigue. Studies P, M2, F2, and F3 are journal articles, and M1 and F1 are conference proceedings.

    Study P used design of experiments to investigate how process parameters affect the surface roughness of as-built EBM-manufactured parts and concluded that beam speed and energy (current) were the most important parameters that influence the surface roughness.

    In studies M1 and M2, EBM-manufactured specimens of cobalt-chromium and titanium alloys were used to evaluate biocompatibility. The blood chamber method quantified the reactions of the human whole blood in contact with the metal surfaces, and the results showed how the as-built EBM surface roughness contributed to coagulation and bone healing.

    Rotating beam fatigue equipment was used in studies F1–F3 and study F1 discussed the size effect on fatigue loaded as-built specimens and included specimens with different sizes and with or without hot isostatic pressing (HIP). Study F2 compared as-built and machined specimens and study F3 investigated how Hirtisation, which is a patented electrochemical surface treatment, and HIP affect the fatigue properties that originate from the electrochemical polishing surface topography. The studies showed that a decreased surface roughness increased the fatigue resistance while the stress concentrations (Kt) in the surface of EBM-manufactured specimens decreased.

    The thesis concludes that EBM-manufactured as-built surfaces are suitable for direct contact with the bone, and that HIP does not improve the fatigue resistance of parts with as-built surfaces, where crack initiation starts at notches.

    Compositionally-tailored steel-based materials manufactured by electron beam melting using blended pre-alloyed powders2020In: Materials Science & Engineering: A, ISSN 0921-5093, E-ISSN 1873-4936, Vol. 771, article id 138587Article in journal (Refereed)
    Abstract [en]

    The paper presents the prospects of additive manufacturing (AM) in metal, using the powder bed fusion (PBF) method Electron Beam Melting (EBM) in fabrication specific steel-based alloys for different applications. The proposed approach includes manufacturing of metals from blended pre-alloyed powders for achieving in situ alloying and the material microstructure tailoring by controlling electron beam energy deposition rate EBM tests were conducted with the blends of 316L stainless steel and Colferoloys 103 and 139, corrosion- and abrasion-resistant iron based materials commonly used for plasma spray coating. Thorough microstructure analysis of the manufactured sample was carried out using electron microscopy and measurements of microhardness and elastic modulus was carried out using nanoindentation. It is concluded that implementation of blended powder pathway in PBF AM allows to widen the scope of available materials through diminishing the dependence on the availability of pre-alloyed powders. Together with beam energy steering this pathway also allows for an effective sample microstructure control at different dimensional scales, resulting in components with unique properties. Therefore, the implementation of ‘blended powder pathway’ in PBF AM provides a possibility of manufacturing components with the composite-like and homogeneous zones allowing for the microstructure control and effectively adding a “4th dimension” to “3D printing".

    Steel-based functionally gradient materials obtained via Electron Beam Melting2019In: Proc. Alloys for Additive Manufacturing Symposium AAMS2019, 2019Conference paper (Refereed)
    Abstract [en]

    Recent developments in metal Additive Manufacturing (AM) technologies have introduced great capabilities unparalleled by conventional manufacturing, not only in achieving freeform geometries, but also in opening new possibilities to tailor the microstructure/properties of materials by controlling process parameters. Electron Beam Melting (EBM) is one of the most important members of the Powder Bed Fusion(PBF) family; it uses a focused electron beam to melt metal powder in a layer by layer approach. One of the main challenges that EBM faces nowadays is the lack of commercially available materials (most of them are Ti-based or Ni-based alloys). Therefore, there is a strong interest to further develop the process for new materials, including steel-based ones. In this investigation two steel-based powders; stainless steel 316L and a tool steel developed by Uddeholm, were used to manufacture functionally graded materials. A special hardware setup using a single powder dispenser was installed in the EBM system, where powders were placed separately to manufacture 10x10x10 mm cubes. SEM images of the specimens’ polished cross sections show a gradual microstructural transition from characteristic 316L one on the bottom of the specimens to the tool steel towards the top. Nanoindentation experiments confirmed a consequent gradient in hardness and elastic modulus, which gradually increase towards top surface. These results show great possibilities to tailor microstructure and mechanical properties by combining different powders in the EBM technology. Potential applications include the tooling industry, where hard and wear-resistant materials are demanded on the surface whether tougher and more ductile behavior is desirable on the core of the tool.

    Influence of beam current on microstructure of electron beam melted Ti-6Al-4V alloy2019In: Progress in Natural Science, ISSN 1002-0071, E-ISSN 1745-5391, Vol. 29, no 4, p. 440-446Article in journal (Refereed)
    Abstract [en]

    The defect microstructure of the samples manufactured from Ti-6Al-4V powder was studied using electron beam melting (EBM) in the beam current range of 17 - 13 mA. The hybrid digital complex combined positron lifetime spectroscopy and coincidence Doppler broadening spectroscopy was used to characterize the defect structure of the materials. The microstructure and defects were also analyzed by transmission electron microscopy. It has been established that the main type of the defects in the EBM manufactured samples is dislocations. According to the conducted measurements and calculations, the dislocation density in the EBM manufactured samples exceeds by two orders the similar value for the cast Ti-6Al-4Valloy. Formation of Ti-Ti-Al nanoscale clusters has been found in the EBM manufactured samples.

    Accelerating sustainable society and a flourishing Scandinavia through a living and communicating network of AI-summits2019Conference paper (Refereed)
    Abstract [en]

    The need for a radical transformation of society, business and way of life towards sustainability is by now widely accepted and acknowledged in the Mid Scandinavian region. This transformation also occurs as a major objective in the UN Sustainable Development Goals, both nationally and locally. However, after creating awareness, moving from knowing to doing is now the real challenge. Pushing for sustainability in strategies and visions, or even providing extensive funding for projects related to sustainable development is not doing the job fast enough. One obvious reason being that the more sustainable ideas and solutions of the future do require new levels of systems thinking and solutions on the level of the “whole system”. That in turn is dependent on connections and relations across traditional silos and organizational borders that currently does not exist. Therefore, stakeholders from Sweden and Norway are currently experimenting together on using a living and communicating network of Appreciative Inquiry Summits to accelerate sustainable, circular, and flourishing development in Scandinavia. The initiative is designed as an innovation project with hands-on exploring, prototyping, as well as researching how to accelerate the desired transformation. The project, called SMICE, is inspired by the “whole system in the room” approach of the amazing initiative “Sustainable Cleveland 2019”. However, as the context of this initiative is a large sparsely populated region, including also several countries, the set up now evolving is moving beyond just one annual big AI-summit towards more of a distributed system, “ecosystem”, or network of AI-summits and other resources that live, communicate and relate to each other continuously. During this presentation we will share our progress made, results, learnings, challenges, insights, and practices from our exciting and important journey so far.

    How Quality Management Needs Emergence for Engaging Agenda 2030: As “improving” increasingly means getting a complex system to take transformative steps towards sustainability and flourishing2019Conference paper (Refereed)
    Abstract [en]

    Purpose

    If not now, when? The UN Sustainable Development Goals (SDGs) are getting increasing attention, and there is an acknowledgement that the challenges ahead, as well as the solutions needed, often are complex. In contrast, the historical strengths of Quality Management (QM) have been in situations when cause-effect relations can be analyzed and understood, when technical expertise can provide the answer, where the application of “best practice” is helpful, where order is a virtue. When dealing with complexity, leaders who are tempted to impose this kind of command-and-control style will often fail. Success rather comes from setting the stage, stepping back a bit, allowing patterns to emerge, curiously tracking what takes place, spreading what is being learned, and scaling up success. Such a leadership and practice has been referred to as the fourth and called for “Emergence Paradigm” of QM. The purpose of this paper is to contribute with knowledge concerning how the Emergence Paradigm of QM comes into play when getting organizations and the world to take action on Agenda 2030.

    Methodology/Approach

    The paper is based on dialogic action research and presents the case and emergent process of 60 Swedish authorities getting to collective action on Agenda 2030.

    Findings

    The paper highlights how QM may contribute to realizing the Agenda 2030 by dynamically combining the strengths of the past paradigms with new practices and mind-sets related to complexity and emergence.

    Value of the paper

    The paper provides new insights that may help to take the bold and transformative steps urgently needed to shift the world onto a sustainable and resilient path.

    Metaphors we manage and develop quality by2020In: International Journal of Quality and Service Sciences, ISSN 1756-669X, E-ISSN 1756-6703Article in journal (Refereed)
    Abstract [en]

    Purpose: Metaphors are a powerful and human way of understanding and experiencing one kind of thing in terms of another. In quality management (QM), several metaphors are used to describe and bring to life the often-abstract QM concepts and systems. These metaphors are of great importance for how QM is understood, communicated and practiced. However, the metaphors of QM have seldom been systematically screened or put in focus, neither the topic of a critical discussion. The purpose of this paper is hence to contribute with a screening of the metaphors currently used, within QM literature and in practice among QM leaders, and then elaborate on their potential for improvement and development. Design/methodology/approach: The paper is based on a literature review combined with interviews of QM leaders. Findings: The paper highlights that the current QM metaphors provide intuitive associations to properties such as stability, shelter, and structure, but not to the important dynamic properties of QM, such as learning, or to the critical role of people in QM. What can be seen as core properties of QM are communicated by texts or labels added on to metaphors with properties that often are in sharp contrast to them. The paper also provides suggestions for further improvements and development. Originality/value: The paper highlights the area of metaphors within QM as an important area for future research. It also provides insights concerning the successful use and selection of metaphors in future QM practice.

    Värdeskapande intern kommunikation med Lean kommunikation och kommunikativt ledarskap: Modell för Lean kommunikation för att stärka och medvetet arbeta med värdeskapande intern kommunikation i Leanbaserade verksamheter,2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The    purpose of this study was to explore how Lean based/Lean inspired    enterprises in Swedish public sector acts to attain value-adding internal    communication. The starting point was that the contemporary demographic    development combined with demands for cost-effectiveness entail challenges    for municipalities to safeguard welfare and customer satisfaction, and that    this task needs to start internally towards the employees in order to bring    effects externally towards the customers. Lean communication and    communicative leadership has arisen as two relatively new concepts which    have not yet been extensively explored, but which aim precisely at    value-adding communication. This study focussed on these two concepts at a    theoretical level and explored how they can be utilised practically and    strategically in order to improve value-adding internal communication. The    empirical data consisted of semistructured interviews with 15    managers/leaders from six municipalities, which have been analysed with qualitative    content analysis. The conclusion was that there existed a relatively    substantial congruity between the respondents concerning what was considered    success factors, what distinguishes a good communicative leader and how they    handled internal communication in the daily work. Clarity and visualisation    were the most frequently aspects mentioned. Additionally, the linkage to    Lean communication and communicative leadership was palpable – even though    not all of the respondents were familiar with or used the concepts, they    were utilising them subconsciously. However, only a minority of them had    functioning strategies to facilitate leaders to be more communicative and    several of them acknowledged shortcomings concerning follow-up, evaluation    and feedback. Based on the study’s results, a model for Lean communication    was created – with a checklist attached – which can be deployed by Lean    enterprises in order to strengthen and consciously work with value-adding    internal communication.

    Laboratory Investigation of Different Insulating Materials Used for Snow Storage2019In: Journal of cold regions engineering, ISSN 0887-381X, E-ISSN 1943-5495, Vol. 33, no 4, article id 04019012Article in journal (Refereed)
    Abstract [en]

    Storage of snow has become of increasing interest for the winter business industry. Covering a pile of snow with an insulating material protects the snow from heat transfer from the surroundings and reduces the melting. Storing snow enables ski resorts to set an opening date, and it can also be used to secure winter sports events that are dependent on snow. Cover materials that are commonly used as insulation are wood-based materials, such as sawdust, and textile materials and sheets. How efficiently a cover material functions as thermal insulation depends on the material characteristics and thickness of the insulating layer. In this study, results from a laboratory experiment are presented, which aimed at comparing different commonly used cover materials, as well as some other materials that have not previously been used as thermal insulation on snow. Different layer thicknesses were also investigated. The results show that the insulating capacity of sawdust is reduced with time. Despite degrading insulating properties with time, sawdust is still considered one of the best materials to use as insulation on snow, and it is also more efficient than the textile materials investigated in this study. Doubling the textile layers or adding a three-dimensional (3D) spacer textile, which implies adding a layer of air between the textile and the snow, reduces the snow melting. Water absorption, water transport, and evaporation of water affect the melting. In this work, evaporative cooling did not prove to reduce melting; therefore, it was not evident whether a textile material should be permeable. An interesting material used in the study was Quartzene, which absorbed all the melt water and protected the snow most efficiently of the materials tested.

    Estimation of muscle work in cross-country sit-skiing2019Conference paper (Refereed)
    Abstract [en]

    Introduction: In Nordic skiing all sitting athletes compete in the same event competition. The sitting positions differ between athletes. Most of the athletes sit knee-seated, or with their thighs tilted downward (KL) and free to move their trunk. Some athletes do not have the possibility to sit in that position and therefore adjust their sitting position. For example, athletes with reduced muscle control in hips and lower trunk sit with their knees higher than their hips (KH) to increase stability.

    Purpose: The purpose of this study was to examine how sitting position KL and KH affects the muscular power.

    Methods: One female able-bodied athlete performed one test session in each sitting position (KL and KH) comprising five times 3 minutes sub-maximal exercise and a maximal time-trial in a double-poling ergometer (ThoraxTrainer A/S, Denmark). During the tests 3D kinematics (Qualisys AB, Sweden), pole forces and power output were measured. From the measured data, participant and test specific musculo-skeletal inverse-dynamics simulation models were created using the AnyBody Modelling system (AMS 6.0, Anybody Technology A/S, Denmark). From the simulations of submaximal exercise power output 37 W, 52 W and maximal time-trial the muscular metabolic power (mMP) was computed according to Holmberg (2013).

    Results: The power output in maximal exercise was higher in KL (90.1 W) compared to KH (74.7 W). During both submaximal and maximal exercise, the total muscular metabolic power was larger in KL compared to KH (KL mean 861 W and KH mean 682 W). The muscular metabolic power also showed larger relative involvement of legs in KL (KL mean 18 % and KH mean 4 %) and larger relative involvement of arms and trunk in KH.

    Conclusion: That sitting position KL compared to KH is related to higher performance for athletes without impairment in hips and trunk is known before (Gastaldi, 2012). However, the results from this study explains why performance is higher in KL, i.e. that larger muscular metabolic power are produced in the legs. This study also shows the size of the involvement of legs, which could be interesting for development of classification rules.

    Skolans om lärande organisation: En studie   av PRIO och dess effekter i ett hållbart utvecklingsarbete2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The purpose of this study was to develop   more knowledge about the school as a learning organization.

    Design: A qualitative case study was conducted, where   the improvement program PRIO and its effects on the schools in Landskrona were   studied. The aspects implementation, long term improvement, the effects of   PRIO in the schools today, increase of quality for the students and the   connection between the schools' development spheres and the research field of   learning organizations in general were examined.

    Findings: The conclusion was that the implementation   was successful in the initial phase, but that the improvement then faded in   more than half of the schools. This can partly be linked to large staff turnover   among the principals, but also to the fact that in many cases the PRIO work   has not been part of the schools' systematic quality management. The schools   experiences an increase of quality for the students, but the connection to   PRIO is not entirely evident. More than half of the development spheres that   the schools have worked with correlate with the spheres highlighted as   essential in the research field around learning organizations. The schools   developed a learning organization through the PRIO work, but not all schools   have been able to maintain it over time.

    Co-creation - making it happen2019In: 22nd QMOD conference: ON QUALITY AND SERVICE SCIENCES ICQSS 2019, 13-15 OCTOBER / [ed] Su Mi Dahlgaard-Park & Jens J. Dahlgaard, 2019Conference paper (Refereed)
    Abstract [en]

    Organisations continuously meet different challenges, often ones that are both difficult and complex. Identified challenges include, for instance, costumers becoming more changeable and volatile as well as organisations needing to become more sustainable in several dimensions and to having a structured and systematic method for working with quality. Municipalities are not excluded from these challenges and need to face the challenge of demands from citizens as well as be efficient and effective at the same time.New ways of working and doing things need to be developed and adapted to meet and fulfil organisational challenges. Co-creation, which is a collaborative process to identify and shape the desired goals, can be a method that allows organisations to establish new ways of working and creating supportive methods. In addition, a collaborative process facilitates the adoption of new ways of working since it is easier to do that through actions rather than thinking oneself into a new way of acting.

    Purpose: The purpose is to describe the process of co-creating a dialogue model that aim to increase citizen value in a municipality organisation. The purpose is also to present the results from the development process and evaluate the chosen model.

    Methodology/Approach: A dialogue model was developed through a co-creation process conducted through a series of workshops, discussions and interactive tasks. The whole process was carried out in three steps. In the first step, success factors for a constructive dialogue emanating from citizen value were identified. In the second step, several dialogue models were developed, tested and evaluated, and one model was chosen. In the third step, the chosen model was evaluated.

    Findings: Evaluating the real-life use of the model supports the statement that the process has delivered a model that enables the requested prerequisites for constructive dialogues such as, for example, the opportunity for preparation, structured and transparent documentation and enabling a holistic view in the dialogue model. Co-creation that has involved co-workers have contributed to develop the dialogue model to be adapted to their own context.

    Value of the paper: Using a co-creative process when developing and realising a dialogue model enhances the possibilities for an organisational adaption to its own context.

    Type of paper: Case study

    Interlinking Lean and Sustainability: How ready are leaders?2019In: The TQM Journal, ISSN 1754-2731, E-ISSN 1754-274X, Vol. 31, no 2, p. 136-149Article in journal (Refereed)
    Abstract [en]

    Purpose: The purpose of this paper is to explore evidence of interlinkages between Lean and sustainability among organisational leaders in the early stages of Lean implementation.

    Design/methodology: A multiple-site case study was conducted to study the connections between Lean and sustainable development during the implementation stages of a Lean practice. In-depth interviews were conducted with managers about their knowledge and understanding of the interlinkages between Lean and sustainable development. The findings were then used as an analytic frame to determine whether these interlinkages were present in the organisation.

    Findings: Evidence of interlinkages between Lean and sustainable development was found; however, their presence was incomplete and inconsistent across clinics.

    Research implications: Insights from the research can help organisations plan for the implementation of Lean practice, particularly when a sub-goal is to achieve sustainable development.

    Originality/value: The study shows the importance of focusing on managers’ knowledge and understanding of the interlinkages between Lean and sustainable development when implementing Lean in order to utilise Leans full potential to achieve sustainability.

    Att praktiskt sätta kunden i centrum”: En utvärdering av en organisation som har implementerat ett agilt arbetssätt utifrån metodiken Scrum.2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The research is based on the fact that there is a knowledge gap in evaluations of companies that implement the working method Scrum. There is a connection between the culture of an organization and how it can effectively and successfully implement an agile approach (Ilvari, Ilvari, 2011). The researcher did a semi-structured interview with employees. The purpose of the study was to evaluate the implementation of Scrum as a method and how the organization works with customer insights. The result shows that a majority of employees experience a higher commitment and greater motivation thanks to the new way of working. Putting the customer at the centre is something that requires a lot of focus. And much from the organisation's leaders. Here the organisation's leaders have been highly involved. Some improvement points were also identified in the research, such as systematically measuring and disseminating customer insights, developing the work of becoming a learning organization, and That the management does not work strategically with the organisation's culture.

    Marine Polysaccharide-Collagen Coatings on Ti6Al4V Alloy Formed by Self-Assembly2019In: Micromachines, ISSN 2072-666X, E-ISSN 2072-666X, Vol. 10, no 1, article id 68Article in journal (Refereed)
    Abstract [en]

    Polysaccharides of marine origin are gaining interest as biomaterial components. Bacteria derived from deep-sea hydrothermal vents can produce sulfated exopolysaccharides (EPS), which can influence cell behavior. The use of such polysaccharides as components of organic, collagen fibril-based coatings on biomaterial surfaces remains unexplored. In this study, collagen fibril coatings enriched with HE800 and GY785 EPS derivatives were deposited on titanium alloy (Ti6Al4V) scaffolds produced by rapid prototyping and subjected to physicochemical and cell biological characterization. Coatings were formed by a self-assembly process whereby polysaccharides were added to acidic collagen molecule solution, followed by neutralization to induced self-assembly of collagen fibrils. Fibril formation resulted in collagen hydrogel formation. Hydrogels formed directly on Ti6Al4V surfaces, and fibrils adsorbed onto the surface. Scanning electron microscopy (SEM) analysis of collagen fibril coatings revealed association of polysaccharides with fibrils. Cell biological characterization revealed good cell adhesion and growth on bare Ti6Al4V surfaces, as well as coatings of collagen fibrils only and collagen fibrils enhanced with HE800 and GY785 EPS derivatives. Hence, the use of both EPS derivatives as coating components is feasible. Further work should focus on cell differentiation.
