    Collaborative problem solving in the context of early childhood intervention – the link between problems and goals2015In: Scandinavian Journal of Disability Research, ISSN 1501-7419, E-ISSN 1745-3011, Vol. 17, no 3, p. 221-239Article in journal (Refereed)
    Abstract [en]

    Swedish Child and Youth Habilitation Services (C-YHS) for children with disabilities and their families' build on regular planning meetings involving families and professionals, and appointments and interventions implemented between meetings. This study explores the content of issues discussed at planning meetings, and the relation between content and activities implemented in everyday interventions. Longitudinal data from five families and their C-YHS-teams were used. Data were analyzed using conventional content analysis. The results illustrate a process with a high degree of correspondence between families' concerns, experienced problems, the formal decisions and the activities they generated. Concerns were focused on the future, and related actions focused on supporting adults in the environment, mostly the parents, thus indirectly relating to the child. Problems were focused on the current situation, and to a larger extent concerned actions directly related to the child. Although a family-centred service, interventions focused on the proximal environment, may be underreported.

    Identifying and Building on Family Strength: A Thematic Analysis2009In: Infants and young children, ISSN 0896-3746, E-ISSN 1550-5081, Vol. 22, no 4, p. 253-263Article in journal (Refereed)
    Abstract [en]

    In family-centered intervention, one important issue is to support families' different ways to manage stress. The purpose of this study was to investigate whether professionals encourage positive coping strategies in families of children with disabilities. Data (videotaped planning meetings and interviews) from 5 families enrolled in intervention programs were used. The data were analyzed deductively by applying theoretical concepts of 4 types of positive coping. Goal-directed problem-focused coping was the most frequently used type of coping, together with spiritual beliefs and practices. Professional encouragement of families' own strategy to solve problems occurring in everyday life must focus not only on explicit problem solving but also on the use of supplemental coping types.

    Problem solving in relation to resources in everyday life in families of children with disabilities: a pilot study2012In: International Journal of Rehabilitation Research, ISSN 0342-5282, E-ISSN 1473-5660, Vol. 35, no 2, p. 102-108Article in journal (Refereed)
    Abstract [en]

    Problem solving is recognized as a skill, helping families of children with disabilities to manage problems in everyday life. Family problem-solving skills may therefore be seen as an important outcome of a child and youth habilitation service. The aim of this pilot feasibility study was to examine the design of a future web-based questionnaire study focusing on problem-solving patterns in relation to resources in families of children with disabilities. The descriptive statistical analyses built on data from 13 families and findings showed an overall satisfactory score distribution for three of the included instruments, whereas two instruments showed floor effects in one third of the items. Findings indicated design problems with data collection related to adapting questionnaires to a web-based survey format and to problems with the stop function that was added. Implementing the main study using web-based surveys needs critical considerations according to the choice of the web tool and the recruitment process.

    Financial reporting in entrepreneurial SMEs: in search of significant areas of financial reporting information2010Licentiate thesis, monograph (Other academic)
    Abstract [en]

    This study sets out from the contemporary discussion on the need of separate financial reporting standards for small and medium-sized enterprises (SMEs), and focuses on financial reporting information needs in the context of entrepreneurial and growth-oriented SMEs. The main purpose of the study is to sort out areas of financial reporting information that are likely to be of significance tomanagers of entrepreneurial SMEs in their provision of information to users. In order to fulfill this purpose data has been collected in several sequential steps where the results of each step have provided with significant input and structure to the carrying through of the following step/s. The first step consists of a literature study of previous empirical studies about accounting information in entrepreneurial contexts. In the second step, interviews have been conducted with accounting experts engaged in the current discussion on the development of accounting standards for SMEs. The third and fourth step consists ofdocument studies of comment letters to the Swedish standard setter Bokföringsnämnden’s (BFN) two drafts of the accounting standard Financial reporting in small companies (K2) and IASB’s Esposure draft of an IFRS for SMEs.

    According to the study results the continuous high demand for financial capitalis a great challenge to managers of entrepreneurial SMEs in their efforts to make their entities develop and grow. In this context, financial reports make up an important tool mainly for informing external capital providers, among which bankers are considered to hold a prominent position. The high demand for financial capital also makes risk capitalists and other external owners more important as financiers of entrepreneurial SMEs than what is the case in SMEs in general. Other important users of entrepreneurial SMEs’ financial reports are customers, suppliers, employees, potential acquirers and management.

    One of the areas of financial reporting information that have been sorted out in this study as likely to be of significance to managers of entrepreneurial SMEs in their provision of information to users is cash flow. Information on cash flow is likely to be significant in the entrepreneurial context not at least since the development of entrepreneurial activities puts a lot of pressure on managers to secure the continuous inflow of cash. The extent to which capital providers make use of cash flow information provides with further argument for its importance in the entrepreneurial context. Also, entrepreneurial entities tend to rely on intangible assets to a high extent, and these assets are in general not sufficiently reflected in the balance sheets. Cash flow provides in this respect straightforward and reliable complementary information that is important when assessing the prospects of the business.

    Besides information on cash flow, information on intangible assets is according to the results of this study likely to be significant in an entrepreneurial context. The possibility to capitalize expenses for intangible investments is crucial not at least to avoid the legal consequences of bankruptcy law, which may be critical to the very survival of development-intensive entrepreneurial SMEs. The importance of innovation as a central part of the entrepreneurial process also makes financial reporting information on intangibles highly relevant from an informational perspective.

    In addition, financial ratios in general, and financial ratios measuring various aspects of growth - i.e. growth ratios - in specific, have been sorted out as likely to be of specific importance to include in the financial reports of entrepreneurial SMEs. Besides disclosure of additional information on individual intangible assets, additional disclosure of information related to the collective earning capacity of ongoing projects - including the business concept of the reporting entity - has also been identified as significant in the entrepreneurial context.

    Risk Assessment for Large-Scale Transport Infrastructure Projects2019In: IOP Conference Series: Materials Science and Engineering / [ed] M. Drusa, I. Yilmaz & M. Marschalko, Institute of Physics (IOP), 2019, Vol. 471, p. 1-10, article id 022005Conference paper (Refereed)
    Abstract [en]

    The identification of risks in the planning phase of a project and the arrangement of impact values has become a fundamental basis of today's various construction projects. Despite robust and well-planned projects, unexpected problems will likely emerge in any stage of the project if possible risks are not identified and assessed beforehand. Therefore, this process has become a requisite in increasing the success as well as minimizing the problems of a project. Large-scale transport infrastructure projects (LSTIPs), technologically equipped projects, meet the essential needs of the recent era but also bring about numerous risks such as financial, technical, managerial, political, economic, natural or legal. Hence, being exposed to such risks in the planning and construction stage of LSTIPs, could lead to negative consequences in the fate of the project. This study aims to develop a conceptual framework which provides a pathway for the planning phase and to offer risk lists and their priority orders that reinforce the construction phase. These aims were achieved by identifying the risk factors that could arise in European and Middle Eastern LSTIPs and detecting significances of the risks according to these types of projects. Data collection was performed through a substantial review of literature and a questionnaire conducted to contracting firms and civil engineering consultancies operating in Europe and the Middle East. According to the findings, the comparison between the leading risks encountered in European and in Middle Eastern LSTIPs revealed that two of the regions were confronted with both similar and different risks. Europe and the Middle East's foremost common risk factor is the financial strength of the client listed under the financial category. When regions are considered individually, Europe gives prior importance to the resource availability risk factor in the economic category whereas increased material cost located under the same category is the primary risk factor for the Middle East. As a result, the data obtained from this research study could be deployed as a standardized risk list in the planning stage of forthcoming LSTIPs as well as a guideline for the assessment phase of priority orders. Furthermore, this study suggests a further and detailed investigation on mitigating risks that occur in LSTIPs.

    Rural household income in transitional China: Spatio-temporal disparity and its interpretation2015In: China: An International Journal, ISSN 0219-7472, E-ISSN 0219-8614, Vol. 13, no 2, p. 151-168Article in journal (Refereed)
    Abstract [en]

    This article aims to investigate the evidence of spatio-temporal disparity in rural household income at the provincial level in China during the 1978-2007 period. A research framework is developed to study the transitional processes of decentralisation, marketisation, urbanisation and globalisation. By computing the Moran's I index and using the spatial regression model, the findings indicate a highly clustered, spatio-temporal disparity in rural household income across the eastern, central and western regions in China during the post-reform era. Rural household income tends to be higher in the eastern provinces in comparison to inland provinces. This disparity is attributed to the impacts from the institutional, economic, social and external transitions that become increasingly significant in the recent decades in China.

    Extended service use and new product possibilities in Swedish trucking2014In: World Review of Intermodal Transportation Research (WRITR), ISSN 1749-4729, E-ISSN 1749-4737, Vol. 5, no 1, p. 80-98Article in journal (Refereed)
    Abstract [en]

    The purpose of this study is to examine how extended services from vehicle manufacturers can enhance value and reduce risk for transportation companies. The research shows that some transportation companies found extended services useful in order to enhance value and to decrease risks, while some of the companies mentioned advantages of not using extended services. Increased customer service and increased up time are some of the value factors. Decreased number of delays and decreased likelihood of breakdowns are some of the risk factors mentioned by the case companies. This study contributes the knowledge by examining the transporters' experiences of using extended services. The study also identifies feedback loop to develop further physical products based on case study and user service package experiences - one key component in the further development is to use simultaneously financial and overall service packages.

    Sustainability performance indicators at shop floor level in large manufacturing companies2017In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 61, p. 457-462Article in journal (Refereed)
    Abstract [en]

    This article investigates sustainability in the performance measurement systems of Swedish manufacturing companies. It builds on a previous study that documents relatively few direct environmental indicators at shop floor level, which raises questions about possible indirect links between existing indicators and the environment that could be used to improve the environmental aspect of company´s sustainability ambitions. 

    A method for identifying and categorizing indirect links to sustainability issues was defined and used. The results suggest that at shop floor level 90% of the indicators have at least an indirect relation to one or more of the sustainability dimensions economy, environment and social, of which 26% are at least indirectly related to the environmental dimension. Despite the many indirect connections, participating companies perceive a need to improve sustainability indicators and some ideas are suggested.

    Knowledge Sharing and Collaboration Through Social Media: The Case of IBM2012In: Proceedings of the 7th Mediterranean Conference on Information Systems, MCIS 2012, Guimarães, Portugal: Association for Information Systems, 2012, Vol. Paper 28Conference paper (Refereed)
    Abstract [en]

    Intellectual capital is the single most important asset owned by any organization. Business continuity, innovation, and long-term sustainability of Small Medium Enterprises depend partly on accumulated organizational knowledge. Knowledge is hard to capture and manage due to its implicit nature. This paper seeks to investigate how Web 2.0 technologies are being used to overcome knowledge sharing and collaboration issues. The new web technologies, which are based on platforms, are referred to as emergent social software platforms (ESSP’s). The use of ESSP’s within a business enterprise to achieve business goals is known as enterprise 2.0 (E2.0). Central to this research is the proposed knowledge sharing cycle model, which has three main stages - internalization, externalization, and objectification. This model is adapted based on the findings of a case study of IBM Corporation. The findings indicate that ESSP’s can be used to support knowledge sharing practices and to help convert knowledge into its different forms.

    Industry Knowledge Characteristics, Prior Experience and New Venture Survival2015In: Academy of Management Proceedings, January 2015 (Meeting Abstract Supplement) 17103, 2015Conference paper (Refereed)
    Abstract [en]

    Recent research suggests that new ventures can overcome threats to their survival by gaining access to technological knowledge from other firms in their industry, even without directly transacting with them or joining their networks. This happens through vicarious learning that allows these ventures to abduct spillovers of industry knowledge made public through patents. We propose that the effects of the industry public knowledge on new venture survival are likely to depend on the unique characteristics of that knowledge—its breadth and newness—and its interaction with a venture’s human capital’s prior experience in the industry. We test and find support for these predictions in a sample of Swedish new ventures. The study contributes to the literatures in organizational learning and new venture survival.

    Effect of Co content on electrodeposition mechanism and mechanical properties of electrodeposited Ni-Co alloy2016In: Transactions of Nonferrous Metals Society of China, ISSN 1003-6326, E-ISSN 2210-3384, Vol. 26, no 2, p. 484-491Article in journal (Refereed)
    Abstract [en]

    Ni-Co coatings with various cobalt contents were electrodeposited from modified Watts bath. The effect of cobalt content on electrodeposition mechanism of the coatings was studied by electro-chemical impedance spectroscopy method (EIS). Surface morphology and crystallographic structure of the coatings were investigated by means of SEM and XRD. Mechanical properties of the coatings were determined using Vickers microhardness and tensile tests. It was found that with increasing the Co2+ ions in electroplating bath, the charge transfer resistance (Rct) of Ni-Co film increased whereas the Warburg impedence decreased. This may be due to enhancement in coverage of cathode surface by Co(OH)2 and higher diffusion rate of metal ions towards cathode surface, respectively. Also, with increasing the cobalt content in the bath, cobalt content in the alloy coating increased anomalously and (111) texture consolidated gradually. With increasing the cobalt content up to 45% in alloy coating, the grain size decreased and consequently, hardness and strength of the alloy increased. Further enhancement of cobalt content up to 55% led to a little decrease in hardness and strength. The maximum ductility was observed for Ni-25%Co coating due to relatively small grain size and compact structure. © 2016 The Nonferrous Metals Society of China.

    The role of transition metal additions on the ambient and elevated temperature properties of Al-Si alloys2017In: Materials Science and Engineering. A, ISSN 0921-5093, Vol. 693, p. 42-50Article in journal (Other academic)
    Abstract [en]

    The principal aim of the present study was to investigate the effects of small additions of several transition metals (Zr, Ni, Ti, V, Cr, La, Y and Nb) on the microstructure, tensile properties and failure mechanisms of as-cast Al-10Si alloys at ambient and elevated temperatures (200 and 250 °C). Transition metal addition led to the formation of (AlSi)3(TiZr), (AlSi)3(CrVTi), Al13(FeCrVTi)4Si4, (AlSi)3(CrV), Al9FeNi AlNbTiZr, AlSiV, AlSiYLa and AlSiZrTiNb phases which are thermally stable until incipient melting of the eutectic compound occurs. Addition of Zr, Ni, Ti, V and Cr gave a substantial improvement in tensile strength at 250 °C, but at the expense of reduced ductility. The strength of transition metals-containing alloys is strongly governed by the size and morphology rather than the volume fraction of the intermetallic phases formed. Large and irregular particles such as (AlSi)3(TiZr), (AlSi)3(CrVTi), AlNbTiZr and AlSiV provided inhomogeneity in the α-Al matrix and act as the principal source of stress concentration, playing an active role in crack initiation. Crack propagation was primarily controlled by plastic deformation of high cooling rate-refined dendrites and modified eutectic silicon particles.

    Al-Si Cast Alloys - Microstructure and Mechanical Properties at Ambient and Elevated Temperature2015Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Aluminium alloys with Si as the major alloying element form a class of material providing the most significant part of all casting manufactured materials. These alloys have a wide range of applications in the automotive and aerospace industries due to an excellent combination of castability and mechanical properties, as well as good corrosion resistance and wear resistivity. Additions of minor alloying elements such as Cu and Mg improve the mechanical properties and make the alloy responsive to heat treatment. The aim of this work is studying the role of size and morphology of microstructural constituents (e.g SDAS, Si-particles and intermetalics) on mechanical properties of Al-Si based casting alloy at room temperatures up to 500 ºC.

    The cooling rate controls the secondary dendrite arm spacing (SDAS), size and distribution of secondary phases. As SDAS becomes smaller, porosity and second phase constituents are dispersed more finely and evenly. This refinement of the microstructure leads to substantial improvement in tensile properties (e.g. Rm and εF). Addition of about 280 ppm Sr to EN AC- 46000 alloy yields fully modified Si-particles (from coarse plates to fine fibres) regardless of the cooling conditions. Depression in eutectic growth temperature as a result of Sr addition was found to be strongly correlated to the level of modification irrespective of coarseness of microstructure. Modification treatment can improve elongation to failure to a great extent as long as the intermetallic compounds are refined in size.

    Above 300 ºC, tensile strength, Rp0.2 and Rm, of EN AC-46000 alloys are dramatically degraded while the ductility was increased. The fine microstructure (SDAS 10 μm) has superior Rm and ductility compared to the coarse microstructure (SDAS 25 μm) at all test temperature (from room to 500 ºC). Concentration of solutes (e.g. Cu and Mg) in the dendrites increases at 300 ºC and above where Rp0.2 monotonically decreased. The brittleness of the alloy below 300 ºC was related to accumulation of a high volume fraction damaged particles such as Cu- Fe-bearing phases and Si-particles. The initiation rate of damage in the coarse particles was significantly higher, which enhances the probability of failure and decreasing both Rm and εF compared to the fine microstructure. A physically-based model was adapted, improved and validated in order to predict the flow stress behaviour of EN AC- 46000 cast alloys at room temperature up to 400 ºC for various microstructures. The temperature dependant variables of the model were quite well correlated to the underlying physics of the material

    Al-Si Cast Alloys - Microstructure and Mechanical Properties at Ambient and Elevated Temperatures2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Swedish industry is a global leader in development and manufacture of automotive and aviation components where the usage of aluminium products is remarkable. In addition to manufacturing aluminium components, casting enables low-cost and low-emission production of complex geometry components with a range of sizes. Aluminium with Si as the major alloying element forms a class of alloys representing the most significant fraction of all cast products, for a wide range of applications due to an excellent combination of castability and mechanical properties, as well as good corrosion resistance, wear resistance and recyclability. The microstructure in Al-Si alloys strongly governs their mechanical properties. Several industrial practices such as eutectic modification and alloying are well-known to improve mechanical properties. Al-Si cast alloys generally suffer a lack of ductility and poor high temperature properties due to presence of either brittle or thermally unstable phases. The aim of this work is to study the explicit role of each microstructural constituent on the behaviour of Al-Si cast alloys at room and high temperatures. The results will accordingly highlight the potential for improvement in properties of such alloys.

    Casting defects have an immediate and negative effect on the properties of Al-Si alloys and reducing the overall level of defects substantially improves tensile properties. An increased cooling rate refines all microstructural features and reduces volumetric porosity which leads to substantial improvement in tensile properties (e.g. Rm and εF) at any test temperature. Modification of eutectic Si-particles (through Sr-addition) generally has a positive effect on alloy ductility. Depression in eutectic growth temperature as a result of eutectic modification was found to be strongly correlated to the level of modification irrespective of coarseness of the microstructure.

    Addition of transition metals (Ni-Ti-Zr-Cr-V) to Al-Si improves tensile strength, particularly at temperatures above 200 ºC caused by formation of thermally stable intermetallic compounds. Below 200 ºC however, a substantial potential for improvement through solute-reinforcement was obtained.

    A physically-based constitutive model with a wide validity range was successfully developed to describe the flow behaviour of Al-Si alloys at different temperatures, as a reliable input for finite element simulation.

    A dislocation density based constitutive model for as-cast Al-Si alloys: Effect of temperature and microstructure2017In: International Journal of Mechanical Sciences, ISSN 0020-7403, E-ISSN 1879-2162, Vol. 121, p. 164-170Article in journal (Refereed)
    Abstract [en]

    The flow stress of an as-cast Al-Si based alloy was modeled using a dislocation density based model. The developed dislocation density-based constitutive model describes the flow curve of the alloy with various microstructures at quite wide temperature range. Experimental data in the form of stress-strain curves for different strain rates ranging from 10−4 to 10−1 s−1 and temperatures ranging from ambient temperature up to 400 °C were used for model calibration. In order to model precisely the hardening and recovery process at elevated temperature, the interaction between vacancies and dissolved Si was included. The calibrated temperature dependent parameters for different microstructure were correlated to the metallurgical event of the material and validated. For the first time, a dislocation density based model was successfully developed for Al-Si cast alloys. The findings of this work expanded the knowledge on short strain tensile deformation behaviour of these type of alloys at different temperature, which is a critical element for conducting a reliable microstructural FE-simulation.

    A Novel Approach for the Assessment of Eutectic Si Modification and Tensile Properties of Al-Si Cast Alloys2015Conference paper (Refereed)
    Abstract [en]

    This study presents a correlation between the depression in eutectic growth temperature, as a result of modification, and the tensile properties of Al-Si cast alloys. In order to study the role that Sr exerts on the solidification behavior, modification and mechanical properties, controlled solidification experiments accompanied with thermal analysis using three mold materials for various cooling conditions, and tensile testing were conducted on Al-Si alloys with several Sr levels (~ 35-500 ppm). The gradient solidification technique was applied to produce directional solidified tensile test specimens comprising low level of defects. The depression in growth temperature of eutectic Si was found to be correlated with the Sr additions and the tensile properties (e.g. elongation to failure and tensile strength).

    Assessment of modification level in En AC-46000 aluminum casting alloy using thermal analysis and microscopic evaluation2015In: Light Metals 2015, The Minerals, Metals, and Materials Society, 2015, p. 955-960Conference paper (Refereed)
    Abstract [en]

    The quantitative methods for controlling and predicting the level of Si modification in EN AC-46000 aluminum cast alloys were examined using thermocouples (thermal analysis) and optical microscopy (image analysis). A wide range of Sr, from 37 to 486 ppm, was added to the alloy. The alloys were cast using three different molds providing different cooling rate and consequently varied microstructure coarseness. Large difference in nucleation and growth temperature of unmodified and modified alloy was found irrespective of coarseness of microstructure. The depression in growth temperature of eutectic Si found to be strongly correlated to content of modification agent as well as modification level. Thermal analysis technique was realized as a non-biased, accurate and inexpensive approach for on-line prediction of Si modification level in the EN AC-46000 alloy cast under different cooling rate.

    The role of Sr on microstructure formations and mechanical properties of  Al-Si-Cu-Mg casting alloy2013Conference paper (Refereed)
    Abstract [en]

    The aim of the paper is to assess the role of Sr modification on eutectic Si, Fe-rich intermetallics and porosity and their responses to the mechanical properties of a commercial high pressure die cast alloy Al-Si-Cu-Mg with Fe level up to 1%. Tensile test samples with a variety of coarsenesses, containing different Sr levels were cast using the gradient solidification technique, that enables a study of the solely influence of Sr on microstructure and tensile properties. The modification altered the morphology and size of eutectic silicon, as well as the characteristics and distribution of Fe-rich intermetallic and porosity. The tensile test results indicate that eutectic Si modification is not a guarantee for improved mechanical properties due to the presence of a variety of Fe-intermetallics and porosity that tend to have a larger role on initiating and propagating cracks leading to premature failures in these commercial alloys.

    Effects of microstructure and defects on tensile and fracture behaviour of a HPDC component: Potential properties and actual outcome of En AC-44300 alloy2014In: Light Metals 2014 / [ed] J. F. Grandfield, John Wiley & Sons, 2014Conference paper (Refereed)
    Abstract [en]

    The aim of present work is to study the influence of microstructure and defects on the mechanical properties of a structural high pressure die cast (HPDC) component of a commercial Al-Si based foundry alloy, EN AC-44300. The alloy which contains mainly 12% Si and 0.7% Fe, is a successful application of a die-casting alloy for the automotive market. Tensile test specimens were extracted from both high pressure die cast components and from ones with comparable microstructures produced through gradient solidification technique, which offers specimens with low levels of defects. The microstructure and defects available in the component were well mapped via X-ray inspection system, optical and scanning electron microscopy.  The results clearly confirmed the components’ performance dependency to configuration of defects and Si morphology as well as revealed the potential of the alloy in terms of ultimate tensile strength and ductility.

    Effect of cooling rate and eutectic modification on texture and grain structure of Al-Si-Cu-Mg die cast alloy2016In: La Metallurgia Italiana, ISSN 0026-0843, Vol. 108, no 6, p. 5-8Article in journal (Refereed)
    Abstract [en]

    The effect of cooling rate and eutectic modification on texture evolution and grain structure of an Al-Si-Cu-Mg die cast alloy were investigated using optical microscopy (OM) and electron backscatter diffraction (EBSD) techniques. Directional solidification technique was utilized to produce as-cast specimens having low level of casting defects with controlled microstructural scale: specimens with average SDAS of 10 and 25 µm. Mode of solidification, cooling rate and eutectic modification did not induce any significant texture in the microstructure. An increase in cooling rate resulted in reduction grain size. High degree of grains orientation randomness was found in high cooling rate regardless of modification treatment.

    High Temperature Tensile Deformation Behaviour and Failure Process of an Al-Si-Cu-Mg Cast Alloy: The Microstructural Scale Effect2015In: Materials & design, ISSN 0264-1275, E-ISSN 1873-4197, Vol. 86, p. 361-370Article in journal (Refereed)
    Abstract [en]

    In this study the high temperature tensile deformation behavior of a commercial Al–Si–Cu–Mg cast alloy was investigated. The alloy was cast with two different cooling rates which resulted in average secondary dendrite arm spacing of 10 and 25 μm, which is typical of the microstructure scale obtained from high pressure die casting and gravity die casting. Tensile tests were performed at different strain rates (10− 4 s− 1 to 10− 1 s− 1) and over a wide temperature range from ambient temperature to 500 °C. The fine microstructure had superior tensile strength and ductility compared to the coarse microstructure at any given temperature. The coarse microstructure showed brittle fracture up to 300 °C; the fracture mode in the fine microstructure was fully ductile above 200 °C. The fraction of damaged particles was increased by raising the temperature and/or by microstructure coarsening. Cracks arising from damaged particles in the coarse microstructure were linked in a transgranular-dominated fashion even at 500 °C. However, in the fine microstructure alloy the inter-dendritic fracture path was more prevalent. When the temperature was raised to 300 °C, the concentration of alloying elements in the dendrites changed. The dissolution rates of Cu- and Mg-bearing phases were higher in the fine microstructure.

    Team-based global organizations: the future of global organizing2015In: The future of global organizing: progress in international business research / [ed] Verbeke, Alain, van Tulder, Rob, Drogendijk, Rian, Bingley: Emerald Group Publishing Limited, 2015, 10, p. 227-243Chapter in book (Refereed)
    Abstract [en]

    Purpose

    We propose team-based organizing as an alternative to more traditional forms of hierarchy-based organizing in global firms.

    Methodology/approach

    Advancements in the study of global teams, leadership, process, and outcomes were organized into four themes: (1) openness toward linguistic and value diversity as enhancing team creativity and performance, (2) knowledge sharing in team-based organizations, (3) the significance of social capital for global team leader role success, and (4) shared leadership, satisfaction, and performance links in global virtual teams.

    Findings

    We identify questions at three levels for bringing research on team-based organizing in global organizations forward. At the within-team individual level, we discuss the criticality of process and leadership in teams. At the between-teams group level, we draw attention to that global teams also need to focus on relationships and interactions with other teams within the same global firm, for example, when sharing knowledge. With respect to the across-teams organizational level, we highlight how bringing people together in global teams from different organizational units and cultures creates the potential for experiential individual and team-based learning, while making the firm more flexible and adaptable.

    Theoretical implications

    The potential of the relatively underexplored idea of global team-based firms as an alternative to hierarchy open up questions for empirical research, and further theorizing about the global firm.

    Practical implications

    Practitioners can learn about organizational, team, and individual challenges and benefits of global team-based organizing.

    Originality/value

    A century-old dominant organizational form is challenged when moving away from hierarchy- and hybrid-based forms of organizing toward team-based global organizing of work.
