A combined finite-element/discrete-particle analysis of a side-vent-channel-based concept for improved blast-survivability of light tactical vehicles
Authors: Grujicic Mica , Yavari Ramin , Snipes Jennifer , Ramaswami S 
Published: January 2016

Purpose
– The recently proposed concept solution for improving blast-survivability of the light tactical military vehicles is critically assessed using combined finite-element/discrete-particle computational methods and tools. The purpose of this paper is to propose a concept that involves the use of side-vent-channels attached to the V-shaped vehicle underbody. Since the solution does not connect the bottom and the roof or pass through the cabin of a light tactical vehicle, this solution is not expected to: first, reduce the available cabin space; second, interfere with the vehicle occupants’ ability to scout the surroundings; and third, compromise the vehicle’s off-road structural durability/reliability. Furthermore, the concept solution attempts to exploit ideas and principles of operation of the so-called “pulse detonation” rocket engines in order to create a downward thrust on the targeted vehicle.

Design/methodology/approach
– To maximize the downward thrust effects and minimize the extent of vehicle upward movement, standard engineering-optimization methods and tools are employed for the design of side-vent-channels.

Findings
– The results obtained confirmed the beneficial effects of the side-vent-channels in reducing the blast momentum, although the extent of these effects is relatively small (3-4 percent).

Originality/value
– To the authors’ knowledge, the present work is the first public-domain report of the side-vent-channel blast-mitigation concept.
Developing ethical competence in healthcare management
Authors: Falkenström Erica , Ohlsson Jon , Höglund Anna T 
Published: January 2016

Purpose– The purpose of this paper was to explore what kind of ethical competence healthcare managers need in handling conflicts of interest (COI). The aim is also to highlight essential learning processes to develop healthcare managers’ ethical competence.Design/methodology/approach– A qualitative study was performed. Semi-structured interviews with ten Swedish healthcare managers from different care providers were carried out twice and analysed through step-wise categorisation.Findings– Four categories of COI were revealed and two ways (passive and active) in which COI were handled. Ethical guidelines did not help the healthcare managers to handle the COI, and none of the managers made use of any sort of systematic ethical analysis. However, certain ethical competence was of great importance to identify and handle COI, consisting of contextual understanding, rational emotions, some theoretical knowledge and a suitable language. Organising work so that ethical analysis can be carried out is of great importance, and top management needs to clearly express the importance of ethical competence and allocate resources to allow adequate learning processes.Originality/value– This paper highlights the management level and focuses on how work-integrated learning-processes can enable ethical competence. Ethical competence at the management level is essential both to comply with the constitution and legal requirements regarding healthcare, and so that managers are able to analyse COI and justify their decisions.
Business and innovation resources
Authors: Löfsten Hans 
Published: January 2016

Purpose
– The purpose of this paper is to analyze how new technology-based firms’ (NTBF) business and innovation resources affect firm survival.

Design/methodology/approach
– The study leverages a data set comprised of 131 Swedish NTBFs located in 16 incubators. The first part of the analysis investigates the determinants of firm survival, and the second presents a statistical analysis. The business resources examined in this study consist of business planning and localization variables and four latent variables are developed. Patents at the firm start or during the firm’s first three years are considered as innovation resources.

Findings
– First, this study shows that the latent business plans variable has a significant positive connection with firm survival. Second, patent development during firms’ initial years is critical to firm survival.

Originality/value
– This study is longitudinal, with the first data collection occurring in 2005 and the second in 2014. The firms’ 2013 annual reports suggest that the firms’ survival rate is 55 percent. This longitudinal research that spans eight years shows how the development of patents is highly significant to firm survival.
Toward an innovation-based perspective on company performance
Authors: Lichtenthaler Ulrich 
Published: January 2016

Purpose– The purpose of this paper is to suggest an innovation-based perspective on company performance and develops a conceptual framework.Design/methodology/approach– This is a research paper, which builds on prior theoretical and empirical management research.Findings– The innovation-based view is grounded in interfirm differences in innovation, and it underscores the opportunities to achieve sustainable superior firm performance by innovating internally besides the increasing trend toward open innovation. The innovation-based perspective goes beyond many firms’ focus on product innovation by examining its interdependencies with other essential first-order innovations such as service, process, business model, and management innovations. The innovation-based perspective further addresses the dynamic and intertemporal transformation of innovation activities based on second-order innovations, which provide a more realistic view of organizations’ innovation over time. This transformation affects organizational boundaries and how a firm sustains superior performance.Originality/value– The innovation-based view revises extant approaches to competition and firm boundaries. The new arguments help to reconcile inconsistent earlier findings, and they deepen the understanding of interfirm differences in innovation and performance.
Integrating sustainability into strategic supplier portfolio selection
Authors: Neumüller Claudia , Lasch Rainer , Kellner Florian 
Published: January 2016

Purpose
– The purpose of this paper is to propose a comprehensive methodology and a problem-specific model for the configuration of the optimal strategic supplier portfolio in terms of traditional, performance-related objectives and sustainability targets.

Design/methodology/approach
– To bridge the research gap, i.e., to align strategic supplier portfolio selection with corporate sustainability targets, a hybrid model of the analytic network process (ANP) and goal programming (GP) is developed. To validate the model, a case example is presented and managerial feedback is collected.

Findings
– By enabling the integration of sustainability targets into strategic supplier portfolio configuration, the hybrid ANP-GP model contributes to research in the area of sustainable supply chain management. Results indicate that simplifying the model by omitting one or more details may lead to unfortunate actions.

Research limitations/implications
– The model has been applied using a case example in the automotive industry. To strengthen the findings, it should be examined under other terms as well.

Practical implications
– Integrating economic, environmental, and social targets into strategic supplier portfolio configuration reduces supply risks and promotes the achievement of the sustainability goals of the purchasing company.

Social implications
– Strategic supplier selection counts among the decisions that have an impact on the environment and society for several years. Configuring economically rational, environmentally friendly, and socially responsible supplier bases supports worldwide efforts towards sustainable development.

Originality/value
– Although sustainable supplier selection has gained importance in recent years, this is the first time that a comprehensive model for the determination of the optimal strategic supplier portfolio in terms of performance-related objectives and sustainability targets has been proposed.

Authors: Liu Wenxing , Zhang Pengcheng , Liao Jianqiao , Hao Po , Mao Jianghua 
Published: January 2016

Purpose– Prior researches have indicated that leadership had an important impact on employee creativity. However, the authors know little about the link between the dark side of leadership-abusive supervision, and employee creativity, as well as its underlying mechanisms. Combining psychological safety theory and social identification theory, the purpose of this paper is to examine the relationship between abusive supervision and employee creativity and the mediating role of psychological safety and organizational identification between abusive supervision and employee creativity.Design/methodology/approach– The authors conducted a multi-source and time-lagged data collection. At Time 1, team members evaluated abusive supervision and psychological safety, and at Time 2, team members evaluated organization identification, and team leaders evaluated members’ creativity. Abusive supervision, psychological safety were evaluated at first stage and organizational identification, creativity were evaluated at second stage, being conducted 2-4 weeks later after the first stage. Finally 423 participants completed two waves of data collection.Findings– The results suggested that, abusive supervision had negative effects on psychological safety and organizational identification, and psychological safety partially mediated the relationship between abusive supervision and organizational identification, and organizational identification fully mediated the relationship between psychological safety and creativity, and the negative effect of abusive supervision on employee creativity was mediated by psychological safety and then by organizational identification.Originality/value– This study identifies and examines the mechanism underlying the effect of abusive supervision, and suggests that psychological safety and organizational identification are two important mediators of the complex relationship between abusive supervision and employee creativity. Therefore, this study not only re-examines the inconsistent effect of abusive supervision on employee creativity, but also represents the first attempt at integrating the psychological safety perspective and social identification theory to study employee creativity and offers important implications for theory development.

Authors: Lu Qiang (Steven) , Pattnaik Chinmay , Shi Mengze 
Published: January 2016

Purpose– The purpose of this paper is to study the spillover effects of marketing expertise on the market performance of domestic firms and multinational enterprises (MNEs). Specifically, this study examines how the adoption of frequency loyalty programs by a domestic firm following an MNE affects the competitive dynamics and the market performance of both firms in a Chinese retail gasoline market.Design/methodology/approach– This study is based on empirical data that were obtained from a quasi-field experiment in which the MNE entered the market with a frequency loyalty program and the domestic firm later responded with a similar loyalty program. The authors measured the impact of the adoption of a frequency loyalty program by the domestic firm on the market performance of both the domestic firm and the MNE.Findings– The authors find that the domestic firm’s adoption of a similar loyalty program significantly increased its market share in the regular gasoline market. The domestic firm’s adoption of a loyalty program also increased the market performance of the MNE in the premium gasoline market.Originality/value– This study explicitly demonstrates the spillover benefits through demonstration effects and provides empirical evidence on specific spillover benefits to domestic firms and MNEs based on their competencies in distinct market segments where they compete.
Ambidextrous supply chain as a dynamic capability: building a resilient supply chain
Authors: Lee Sang M , Rha Jin Sung 
Published: January 2016

Purpose– Developing ambidexterity as a dynamic capability is important for firms to sustain their competitive advantage. Moreover, this capability allows firms to build the resiliency to mitigate enterprise risks. The purpose of this paper is to apply two main theoretical frames from the strategy literature, dynamic capabilities, and organizational ambidexterity, to supply chain management (SCM) to examine mitigation strategies for supply chain (SC) disruptions. The authors empirically investigated how the firm’s SC ambidexterity is developed through a dynamic capability-building process and how this, in turn, can mitigate the negative impact of SC disruptions and improve business performance.Design/methodology/approach– This study conducted a field survey to answer the research questions as there exists no archival database with detailed information on ambidextrous SC strategies and dynamic capability. A total of 316 usable responses were received from managers working in the SC area. Confirmatory factor analysis and structural equation modeling were run on SPSS (version 16.0) and AMOS (version 18.0) to test the hypotheses to answer research questions.Findings– Overall, the results of the study confirmed that a dynamic SC capability-building process is an antecedent of SC ambidexterity, and that SC ambidexterity is important to firms as it mitigate the negative impact of SC disruptions and enhance business performance. To take advantage of an ambidextrous SC, through minimizing the negative impact of SC disruptions and maximizing firm performance, firms should continually search for creative ways to satisfy new market needs and adapt to the fast changing business environment.Originality/value– This study applied a dynamic capability-building process and ambidexterity to SCM. From the resilient SC perspective, the study found that the ability to effectively utilize existing resources and create novel strategies for problem solving plays a critical role in addressing SC disruptions.

Authors: Wang Di , Song Changhui , Yang Yongqiang , Liu Ruicheng , Ye Ziheng , Xiao Dongming , Liu Yang 
Published: January 2016

Purpose
– This paper aims to verify that additive manufacturing technology could be used for the redesign and rapid manufacturing of tools and determine whether the mechanical performance of such tools can satisfy the practical operating requirements.

Design/methodology/approach
– A special key was selected as the research object in this paper. The special key was innovatively redesigned and manufactured directly using selective laser melting (SLM). The function and critical geometries of the special key were first analysed, which was followed by discussions on the geometrical constraints in the manufacturing of typical geometrical features using SLM technology. Next, the special key was redesigned based on the SLM geometrical constraints and the functional requirements. Finally, the key was manufactured using SLM, and the mechanical performance characteristics of the key were determined.

Findings
– The minimal geometrical feature was 0.2 mm when manufacturing thin walls using SLM. The reliable building angle of an overhanging surface was 40°. The top surface quality of the part could be greatly improved through laser surface re-melting. The volume of the redesigned special key based on the SLM process was only one-third to one-fourth of the original key. The mechanical properties, such as tensile strength and micro-hardness, of the samples manufactured using SLM were able to reach the practical operating requirements.

Originality/value
– It is completely feasible to redesign and manufacture precision tools based on the innovative approach of SLM. The advantages of the redesigned tools includes the lack of design restrictions that hinder traditional manufacturing methods, material savings, ability to produce tools that cannot be easily copied and rapid production speed for a small number of tools.
CAD and AM-fabricated moulds for fast cranio-maxillofacial implants manufacture
Authors: Ruiz-Huerta Leopoldo , Almanza-Arjona Yara Cecilia , Caballero-Ruiz Alberto , Castro-Espinosa Homero Alberto , Díaz-Aguirre Celia Minerva , Echevarría y Pérez Enrique 
Published: January 2016

Purpose
– The purpose of this study is to suggest the joint use of computer-aided design (CAD) and additive manufacturing (AM) technology for the fabrication of custom-made moulds, designed for the manufacture of polymethyl methacrylate (PMMA) implants for cranio-maxillofacial reconstruction to reduce their fabrication time. Even though tailor-made skull prostheses with a high technological level and state-of-the-art materials are available in the market, they are not always accessible to the general population in developing countries.

Design/methodology/approach
– Computed tomography data were handled to create a three-dimensional (3D) model of the injury of the patient, by reconstructing Digital Imaging and Communications in Medicine (DICOM) images into an Standard Tessellation Language (STL) file that was further used to design the corresponding implant using CAD software. Accordingly, a two-piece core and cavity moulds that replicated the implant geometry was also CAD designed. The 3D-CAD data were sent to an AM machine (fused deposition modelling) and the moulds were fabricated using polycarbonate as thermoplastic material. A reacting mixture to produce PMMA was poured directly into the fabricated moulds, and left to polymerise until cure. Finally, a clear bubble-free case of study PMMA implant was obtained.

Findings
– The fabrication of CAD-designed moulds with AM, replacing the production of the injury model, resulted in the reduction of the lead-time in the manufacturing of PMMA around 45 per cent. Additionally, the implant showed better fit than the one produced by conventional process. The use of AM moulds for the fabrication of PMMA implants has demonstrated the reduction in lead-time, which potentially can reduce the waiting time for patients.

Social implications
– Currently, the demand of cranio-maxillofacial implants at only the Hospital General de México “Dr Eduardo Liceaga” (HGM) is 4,000 implants per year, and the average waiting time for each patient is between 5 and 10 weeks, including third-party services’ delays and the time needed to obtain the economical resources by the patient. Public hospitals in Mexico lack manufacturing facilities, so patients have to make use of laboratories abroad and most of the population have no access to them. The implementation of this suggested procedure in public hospitals may improve the accuracy of the implant, increase the number of patients attended per year (up to 83 per cent) and the reduction in waiting time can also reduce mortality and infection rates.

Originality/value
– The authors of this paper suggest the joint use of CAD and AM technologies to significantly reduce the production time of PMMA implants by producing moulds rather than the injury model, maintaining the general terms and known steps of the process already established for PMMA implants.
Development of novel additive manufacturing technology: an investigation of a selective composite formation process
Authors: Cunico Marlon Wesley Machado , Carvalho Jonas de 
Published: January 2016

Purpose– The purpose of this study is to present a novel additive manufacturing (AM) technology which is based on selective formation of cellulose-acrylate composite. Besides proposing a process that combines the benefits of fibres and photopolymers, this paper reports the development of material, characterisation of a straight line composite formation, adherence between layers and functional feasibility of the proposed concept.Design/methodology/approach– For the preliminary evaluation of the proposed process, a composite material based on cellulose-photopolymer was developed, while a multi-objective optimisation study indicated the formulation which results in the maximum values of layer adherence, tensile strength of composite and the effect of the water on the mechanical strength of material. For the characterisation of the process, three main subjects were analysed: the characterisation of straight line composite formation, the effect of composite formation process on previous layers and the functional feasibility of technology.Findings– In the material development, the tensile strength of dry composite was identified between 20 and 30 MPa, while the tensile strength of wet composite was between 5 and 12 MPa. It is important to note that the dry and wet cellulose presented tensile strength, respectively, equal to 15 and 1 MPa, indicating the possibility of residual material removal only with the use of water or other soft solvent. The values of adherence between layers (peeling test) were found to be between 0.12 and 0.15 kgf, and the photopolymer formulation which resulted in the maximum adherence has monomer/oligomer ratio equal to 1.5 and 2 per cent wt of photoinitiator percentual. As result of the optimisation study, the material formulation was compounded by monomer – 10 ml, oligomer – 4.5 ml and photoinitiator – 2 per cent, being found suitable to characterise and evaluate the proposed process. The study of composite formation along a straight line showed values of line width between 1,400 and 3,500 μm in accordance with light power, laser velocity and laser beam diameter. On the other hand, the number of previous layers affected by the composite formation varied from 0 to 4, indicating a potential process limit. In the functional feasibility study, a feasible process window which resulted in the maximum dimensional deviation equal to 0.5 mm was identified. In addition, the mean mechanical tensile strength was found to be around 30 MPa for longitudinal laser trajectory (90°) and 15 MPa for transversal laser trajectory (0°), highlighting the anisotropic behaviour of final parts according to the manufacturing strategy.Originality/value– This paper proposed a novel AM technology and also described studies related to the characterisation of this concept. This work might also be useful to the development of other AM processes and applications.
