Enterprise education: a Deweyan perspective
Authors: Pepin Matthias 
Published: March 2013

PurposeThe purpose of this paper is to propose a framework of reflection that opens the way to a fuller understanding of what is meant by learning to be enterprising in schools, particularly during the basic schooling of students (at both the primary and secondary levels). Working from Dewey's philosophy of experience, the paper advances a new definition, in processual terms, of being enterprising and a related model of learning to be enterprising.Design/methodology/approachThe backdrop of this theoretical article is enterprise education, currently associated with a broader view of entrepreneurship. The text begins with a critique of existing definitions of being enterprising, showing their limitations from an educational point of view. It then proposes an exploration of Dewey's philosophy of experience and its educational corollaries, all with a view to sketching out a model of learning to be enterprising.FindingsJohn Dewey's philosophy of experience provides a basis for characterizing the notion of being enterprising in relation to two distinct phases – namely, charting a guiding direction for the action to be undertaken and putting the plan of action to the test in experience. Dewey also highlights the importance of reflexivity throughout this entire process. The coherent structuring of these elements lays the groundwork for a model of learning to be enterprising that simultaneously takes into account action and reflection in the classroom entrepreneurial experience.Originality/valueBeing enterprising is closely bound up with action, thus prompting many authors to set out a parallel between enterprise education and experiential learning, with most working from the model proposed by Kolb. The paper returns to the philosophical bases elaborated by Dewey and his vision of experiential learning, associated with his oft‐quoted maxim of “learning by doing.” The value of this conceptual effort consists in acquiring a more operational representation of learning to be enterprising in schools.
Transformational leadership and personal outcomes: empowerment as mediator
Authors: Krishnan Venkat R. 
Published: March 2013

PurposeCreating and maintaining sustainable businesses require an understanding of the role of leadership in enhancing personal outcomes of employees, and of the processes by which they can be enhanced. The purpose of this paper is to report a study on analyzing how transformational leadership is related to followers’ meaning in life and subjective wellbeing, with psychological empowerment being a mediating variable.Design/methodology/approachData were collected from 285 managers (69 females and 215 males) of a large manufacturing organization in western India. They responded to questions about their superior's transformational leadership and their own empowerment, meaning in life and wellbeing.FindingsEmpowerment mediated the relationship between transformational leadership and follower's meaning in life and wellbeing.Research limitations/implicationsSame‐source bias is a possible limitation of the study. Leader's self‐rating on transformational leadership could be taken, but it would not be as valid as the rating given by followers. Another limitation is the collection of all data at the same time.Practical implicationsThe strong and positive relationship between empowerment and meaning in life sheds light on making followers see greater meaning in life. Attempts to enhance meaning in life should first focus on increasing self‐efficacy. If followers do not have faith in their own capability to do their job, it may not be possible for them to see meaning in life.Originality/valueThis study adds to the existing literature by clarifying the process by which transformational leaders enhance followers’ meaning in life and subjective wellbeing.
Are leadership constructs really independent?
Authors: Rowold Jens , Borgmann Lars 
Published: March 2013

PurposeThe aim of this study is to contribute to the construct validity of leadership styles. Although several theories of leadership emerged in the past decades, integrative research on leadership constructs is rare. Thus, for the first time, the present study critically tests whether the leadership constructs of transformational and transactional leadership, consideration and initiating structure, and leader‐member‐exchange are convergent, or whether they exhibit discriminant validities, as hypothesized by theory.Design/methodology/approachApplying hierarchical structural equation modeling to the multitrait‐multimethod (MTMM) approach, the present study explored the convergent and discriminant validity of leadership constructs based on data from multiple sources. Altogether,N=148 dyads of leaders and subordinates from various industries in Germany participated in the present study.FindingsResults demonstrated evidence for the convergence of the leadership constructs.Practical implicationsIn leadership feedback projects in organizations, practitioners should utilize multiple rating perspectives for adequate descriptions of leadership behaviors.Originality/valueInterestingly, approximately the same amount of variance in the data was due to the rating sources as it was to the leadership constructs, suggesting strong method effects in leadership research. The present study was among the first MTMM approaches that addressed the construct validity of several leadership constructs simultaneously and thus, allows new insight into the overall network of leadership theories.
Differentiation focused supply chain design
Authors: Hilletofth Per 
Published: March 2013

PurposeThe purpose of this paper is to develop a framework for differentiation focused supply chain design (SCD).Design/methodology/approachThis research uses a literature review and case study approach to develop a framework for differentiation focused SCD. The proposed framework has been developed based on the literature review and evaluated against the case study. The case study describes SCD at two Swedish companies; one from the appliance industry and the other from the furniture industry, both having a significant international presence. Empirical data have been collected, mainly from in‐depth and semi‐structured interviews with key persons representing senior and middle management in the case companies.FindingsThis research suggests that differentiation‐focused SCD can be organized into a five‐stage process. It is essential that this process is aligned with new product development (NPD), so they exchange information, and operate based on the same segmentation model. The main benefits of a differentiated supply chain are enhanced competitiveness, as supply chain management (SCM) changes from being a cost center to being a value generating function, and increased profitability, by allowing differentiated customer needs to be satisfied cost‐efficiently. To succeed with developing a differentiated supply chain, logisticians must be extensively involved with both the NPD process and the strategic marketing process.Research limitations/implicationsCurrent models of SCD are simplistic and not well developed. By combining theory with practical applications, this research provides researchers and decision makers with detailed tools for developing a differentiation‐focused SCD process. The research is explorative in nature therefore empirical data from similar and other research settings should be gathered to reinforce the validity of the findings.Practical implicationsThis research provides knowledge and insights on how a differentiated supply chain may be developed. The main implication is that SCD needs to be closely aligned with NPD and marketing in order to gain competitive advantage. Companies may also be able to employ labor closer to the consumption market by focusing on supply chain differentiation.Originality/valueThis research contributes by developing a process for differentiation‐focused SCD, and by demonstrating the main benefits and requirements of a differentiated supply chain.

Authors: Rampersad Giselle , Troshani Indrit , Plewa Carolin 
Published: March 2013

PurposeGiven the increased importance of inter‐organizational networks in fostering innovation, the purpose of this paper is to isolate drivers of the adoption of inter‐organizational systems (IOS) that support innovation processes.Design/methodology/approachBased on qualitative research incorporating a focus group and in‐depth interviews, a network framework is provided for understanding key drivers concerning IOS adoption.FindingsThe research uncovers factors for facilitating coordination and communication efficiencies and outlines the roles that trust and commitment can play in managing innovation within networks through IOS use.Research limitations/implicationsTo enhance our understanding of innovations that are entrenched in networks of heterogeneous actors, this research contributes by employing an interdisciplinary approach as it applies network and relationships marketing literatures to the IOS adoption in innovation settings.Originality/valueThe paper advances theory development on innovation management and technology adoption by offering a network framework, a shift from extant literature's predominant focus on individual and organizational levels.
Strategic sourcing in the textile and apparel industry
Authors: Su Jin 
Published: March 2013

PurposeThe purpose of this paper is to investigate performance outcomes of strategic sourcing, specifically examining how strategic sourcing affects buyer‐supplier relationship, supplier evaluation, and sourcing performance from the buying firm's perspective in the context of the US textile and apparel industry.Design/methodology/approachThis study provides an empirical investigation of a theory‐based model integrating the resource‐based view and the relational view of strategic management. The model is tested using data from 180 US textile and apparel firms by structural equation modeling.FindingsThe survey results indicate that strategic sourcing significantly impacts buyer‐supplier relationships, supplier evaluation, and sourcing performance of buying companies. The study also shows that supplier evaluation significantly influences buyer‐supplier relationship.Research limitations/implicationsGiven that the data are from a specific industry, the generalizability of current findings to other industries may require additional investigation.Practical implicationsSourcing becomes a key strategic consideration for textile and apparel firms to sustain or improve their competitiveness.Originality/valueThe study contributes to the literature by developing a research model based on a multi‐theoretical perspective and conducting a large‐scale empirical survey in the textile and apparel industry and analyzing the model by structural equation modeling. The dynamic textile and apparel industry is a classical representation of global supply chain, characterized by the industry's significant contribution to the world economy and international trade, the extremely worldwide spread supply network, and the tremendous competition in global market. Examining strategic sourcing's influences in this important industry provides many valuable implications for industrial practitioners.
Evaluating alternative industrial network organizations and information systems
Authors: Mittermayer Herwig , Rodríguez‐Monroy Carlos 
Published: March 2013

PurposeThe purpose of this paper is to present a simulation‐based evaluation method for the comparison of different organizational forms and software support levels in the field of supply chain management (SCM).Design/methodology/approachApart from widely known logistic performance indicators, the discrete event simulation model considers explicitly coordination cost as stemming from iterative administration procedures.FindingsThe method is applied to an exemplary supply chain configuration considering various parameter settings. Curiously, additional coordination cost does not always result in improved logistic performance. Influence factor variations lead to different organizational recommendations. The results confirm the high importance of (up to now) disregarded dimensions when evaluating SCM concepts and IT tools.Research limitations/implicationsThe model is based on simplified product and network structures. Future research shall include more complex, real world configurations.Practical implicationsThe developed method is designed for the identification of improvement potential when SCM software is employed. Coordination schemes based only on ERP systems are valid alternatives in industrial practice because significant investment IT can be avoided. Therefore, the evaluation of these coordination procedures, in particular the cost due to iterations, is of high managerial interest and the method provides a comprehensive tool for strategic IT decision making.Originality/valueReviewed literature is mostly focused on the benefits of SCM software implementations. However, ERP system based supply chain coordination is still widespread industrial practice but associated coordination cost has not been addressed by researchers.
Entry barrier's difference between ICT and non‐ICT industries
Authors: Yang Changgyu , Lee Sang‐Gun , Lee Jaebeom 
Published: March 2013

PurposeGiven the increasingly saturated information and communication technology (ICT) market and the intensification of competition among ICT firms, there is a need for a better understanding of entry barriers in the ICT market. The purpose of this paper is to examine the overall characteristics of these entry barriers and identify firms' strategies for achieving market dominance.Design/methodology/approachThe authors examined the overall characteristics of these entry barriers and identified firms' strategies for achieving market dominance by tracking the actual patterns of firms' ICT market entry based on the Bass diffusion model.FindingsThe results indicate that the saturation of the ICT market reduced entry barriers, which strengthened the imitation effect. In addition, entry barriers were lower for ICT firms than for non‐ICT ones. Furthermore, entry barriers were higher for the manufacturing sector than for the service sector, indicating that the innovation effect was stronger for the manufacturing sector than for the service sector, whereas the opposite was true for the imitation effect.Originality/valueThese results suggest that those firms that are planning to enter or are already in the ICT market should develop better strategies for gaining a competitive advantage.
A 3D generalized rigid particle contact model for rock fracture
Authors: Monteiro Azevedo Nuno , Lemos José V. 
Published: March 2013

PurposeThe rigid spherical particle models proposed in the literature for modeling fracture in rock have some difficulties in reproducing both the observed macroscopic hard rock triaxial failure enveloped and compressive to tensile strength ratio. The purpose of this paper is to obtain a better agreement with the experimental behavior by presenting a 3D generalized rigid particle contact model based on a multiple contact point formulation, which allows moment transmission and includes in a straightforward manner the effect of friction at the contact level.Design/methodology/approachThe explicit formulation of a generalized contact model is initially presented, then the proposed model is validated against known triaxial and Brazilian tests of Lac du Bonnet granite rock. The influence of moment transmission at the contact level, the number of contacts per particle and the contact friction coefficient are assessed.FindingsThe proposed contact model model, GCM‐3D, gives an excellent agreement with the Lac du Bonet granite rock, strength envelope and compressive to tensile strength ratio. It is shown that it is important to have a contact model that: defines inter‐particle interactions using a Delaunay edge criteria; includes in its formulation a contact friction coefficient; and incorporates moment transmission at the contact level.Originality/valueThe explicit formulation of a new generalized 3D contact model, GCM‐3D, is proposed. The most important features of the model, moment transmission through multiple point contacts, contact friction term contribution for the shear strength and contact activation criteria that lead to a best agreement with hard rock experimental values are introduced and discussed in an integrated manner for the first time. An important contribution for rock fracture modeling, the formulation here presented can be readily incorporated into commercial and open source software rigid particle models.

Authors: Karban Pavel , Mach František , Dolezel Ivo 
Published: March 2013

PurposeThe purpose of this paper is to present a model of induction heating of aluminium billets rotating in a static magnetic field generated by permanent magnets. The model is solved by the authors' own software and the results are verified experimentally.Design/methodology/approachThe mathematical model of the problem given by two partial differential equations describing the distribution of the magnetic and temperature fields in the system is solved by a fully adaptive higher‐order finite element method in the hard‐coupled formulation. All material nonlinearities are taken into account.FindingsThe method of solution realized by the code is reliable and works faster in comparison with the existing low‐order finite element codes.Research limitations/implicationsThe method works for 2D arrangements with an extremely high accuracy. Its limitations consist mainly in problems of determining the coefficients of convection and radiation for temperature field in the system (respecting both temperature and revolutions).Practical implicationsThe methodology can successfully be used for design of devices for induction heating of cylindrical nonmagnetic bodies by rotation and anticipation of their operation parameters.Originality/valueThe paper presents a fully adaptive higher‐order finite element and its utilization for a hard‐coupled numerical solution of the problem of induction heating.

Authors: Meessen K.J. , Paulides J.J.H. , Lomonova E.A. 
Published: March 2013

PurposeThe purpose of this paper is to present a semi‐analytical modeling technique to describe magnetic fields due to PMs in 3D cylindrical structures. The model is based on 2D Fourier series and is applied to model the magnetic field of checkerboard magnetization patterns for rotary‐linear actuators.Design/methodology/approachThe modeling technique based on Fourier series provides a direct solution of the Poisson and Laplace equation by means of separation of variables and is widely used to describe magnetic fields in electromagnetic devices in 2D coordinate systems. In this paper the magnetic scalar potential is used in the Poisson and Laplace equations.FindingsThe magnetic field calculated by the semi‐analytical model is compared with that obtained by Finite Element Modeling and shows excellent agreement. The calculation time of the semi‐analytical model is approximately 60 times shorter than that of finite element analysis.Research limitations/implicationsThe method as presented in the paper assumes linear material properties, e.g. the non‐linear B‐H characteristics of iron cannot be taken into account. Furthermore, the structure is assumed to be slotless, that is, stator slots or end‐effects cannot be taken into account.Practical implicationsThe semi‐analytical modeling technique is applied to checkerboard magnetization patterns for 2‐DoF actuators in this paper. However, it can be applied to a wide range of slotless cylindrical electromagnetic devices.Originality/valueAs an addition to the common 2D modeling by means of Fourier series, this paper extends the applicability to 3D cylindrical structures. Furthermore, a new checkerboard magnetization is presented which can be used in 2‐DoF rotary linear actuators.
Improved technique for minimizing torque pulsation in Halbach array permanent magnet machines
Authors: Sadeghi Siavash , Parsa Leila 
Published: March 2013

PurposeThe purpose of this paper is to minimize the torque pulsation in Halbach array permanent magnet synchronous machines (PMSMs).Design/methodology/approachBecause of its specific structure, the cogging torque influences the main part of the torque pulsation in a Halbach array PMSM. In this paper, first it is shown that the conventional magnet skewing method does not have a significant effect on the torque pulsation in this motor, and then an improved skewing method with fewer skewing steps is proposed. In this method permanent magnet segments are placed sinusoidally, with two‐step skewing along the rotor. Generalization with different combinations of slots and poles is considered for a Halbach array PMSM.FindingsUsing a detailed finite element method (FEM) it was found that with the proposed technique the cogging torque factor is reduced to as low as 8 percent, while the average value of the torque is maintained near the machine nominal average torque.Practical implicationsHalbach array PMSMs are very good candidates for high dynamic performance applications such as aerospace applications due to their high acceleration and deceleration features. This technique also resolves the mechanical vibration and acoustic noise issues, which are caused by torque pulsation and significantly affect machine performance.Originality/valueThe originality of this paper lies in the FEM results. Since Halbach array PMSMs have a special structure it was shown that the conventional skewing method does not work well for this machine. The new proposed technique has a significant effect on the torque pulsation.
A new approach of power electronic design using a nonlinear average model
Authors: Benachour Redha , Latreche Saïda , El Hadi Latreche Mohamed , Gontrand Christian 
Published: March 2013

PurposeThe present work aims to explain how the nonlinear average model can be used in power electronic integration design as a behavioral model.Design/methodology/approachThe nonlinear average model is used in power electronic integration design as a behavioral model, where it is applied to a voltage source inverter based on IGBTs. This model was chosen because it takes into account the nonlinearity of the power semiconductor components and the wiring circuit effects, which can be formalized by the virtual delay concept. In addition, the nonlinear average model cannot distinguish between slow and quick variables and this is an important feature of the model convergence.FindingsThe paper studies extensively the construction of the nonlinear average model algorithm theoretically. Detailed explanations of the application of this model to voltage source inverter design are provided. The study demonstrates how this model illustrates the effect of the nonlinearity of the power semiconductor components' characteristics on dynamic electrical quantities. It also predicts the effects due to wiring in the inverter circuit.Research limitations/implicationsMore simulations and experimental analysis are still necessary to improve the model's accuracy, by using other static characteristic approaches, and to validate the applicability of the model to different converter topologies.Practical implicationsThe paper formulates a simple nonlinear average model algorithm, discussing each step. This model was described by VHDL‐AMS. On the one hand, it will assist theoretical and practical research on different topologies of power electronic converters, particularly in power integration systems design such as the integrated power electronics modules (IPEM). On the other hand, it will give designers a more precise behavioral model with a simpler design process.Originality/valueThe nonlinear average model used in power electronic integration design as behavioral model is a novel approach. This model reduces computational costs significantly, takes physical effects into account and is easy to implement.
