Extending the application of stakeholder influence strategies to environmental disclosures
Authors: Elijido‐Ten Evangeline , Kloot Louise , Clarkson Peter 
Published: October 2010

PurposeThis paper aims to provide insights into stakeholder expectations regarding the types of disclosures a firm should make, and if dissatisfied with the disclosure policy, whether it will use different intervention strategies in an attempt to induce the desired disclosure outcome.Design/methodology/approachAn inductive qualitative framework is used in the study. In‐depth interviews, triangulated against relevant web site and media releases, are used to identify the salient stakeholders and the major environmental issues in Malaysia. Then an experimental approach is used based on role‐playing whereby experienced participants are introduced to hypothetical vignettes that relate to environmental issues identified.FindingsThe results indicate that the preferred form of disclosure is for the firms to “defend” the reasons behind the environmental event and/or explain what has been done to rectify the situation. With relatively few exceptions, the preferred strategies chosen by various participants align well with the influence strategies identified by Frooman. The findings confirm that although Frooman's model is useful in predicting stakeholder influence strategies, its effectiveness is tempered by the level of significance placed on the event by the stakeholders.Research limitations/implicationsAlthough based on a small sample, the results suggest that stakeholder theory has much to offer in terms of understanding management/stakeholder behaviour and corporate environmental disclosures.Originality/valueThe paper extends the application of stakeholder influence strategies in the “environmental reporting” domain. Likewise, it attempts to address the scarcity of literature taking the view of a wide array of stakeholders and how they choose to influence the firm. Finally, it confirms that stakeholder theory can be extended to aid the understanding of events in non‐western developing economies such as Malaysia.

Adopting a service logic in manufacturing
Authors: Grönroos Christian , Helle Pekka 
Published: October 2010

PurposeThe purpose of this paper is to create a framework for measuring mutually created value in business relationships in the manufacturing sector, which also enables suppliers and customers to share this value between themselves.Design/methodology/approachThe starting point is that manufacturing firms adopt a service perspective or logic for their entire business. The framework created includes a conceptual foundation for understanding the process of mutual value creation as well as theoretical basis and metrics for calculating mutually created value, joint productivity gains (JPGs) and value sharing. The framework for mutual value creation is created conceptually. The theoretical basis for the metrics used for the calculations and the development of the metrics are empirically grounded in a longitudinal case study.FindingsBy matching supplier and customer practices and thereby aligning corresponding processes, resources and competencies, suppliers can support their customers' business more effectively and thus enable the customers and also themselves to create incremental value which can be shared between the business partners. It is showed that the metrics for calculating JPGs and for sharing these gains in the form of additional value for the business partners, through a price mechanism, can be created and used.Practical implicationsFindings of the paper suggest an alternative way of creating value which is geared towards the demands of a service logic applied in business relationships. Productivity can be created jointly and not separately by the supplier and the customer, and an incremental value in the form of a JPG calculated and shared. To be able to do this, the business partners must have access to accounting data, and the customer and the supplier must be willing to open up their books and engage in mutual practice matching. This demands that a service logic is adopted for the entire manufacturing business, not separately for industrial service activities only, which is the traditional approach to studying service in manufacturing.Originality/valueTraditionally, value is viewed as an outcome, not as a process of mutual value creation, the outcome of which can be calculated. Productivity as a joint concept and jointly created productivity gains enable firms to share the gains created through mutual value creation. In the literature so far, productivity and value creation have not been studied as mutual concepts. In addition, approaching the entire manufacturing business from a service logic point of view is also novel.
Exploitation or exploration in service business development?
Authors: Fischer Thomas , Gebauer Heiko , Gregory Mike , Ren Guangjie , Fleisch Elgar 
Published: October 2010

PurposeThe paper aims to explore how dynamic capabilities of sensing, seizing and reconfiguring shape the way in which service business is developed in a broad range of capital goods industries.Design/methodology/approachThe paper takes an interpretative multiple‐case study approach. It seeks to develop primary organizing themes around the key dynamic capabilities and support them with research propositions.FindingsThe findings suggest that companies either exploit or explore the opportunities when it comes to service business development. Moreover, dynamic capabilities differ between the two approaches and predict which way a company chooses.Research limitations/implicationsResearch limitations are mainly due to the nature of qualitative research. The dynamic capabilities identified here are by no means exhaustive; rather, they indicate directions for future research.Practical implicationsThe research findings provide guidance to managers as to how the strategic shift towards services is influenced by dynamic capabilities.Originality/valueDespite difficulties associated with service business development, the literature remains relatively silent on dynamic capabilities. However, dynamic capabilities are essential to the strategic shift towards service business.
Comparing provider‐customer constellations of visibility‐based service
Authors: Holmström Jan , Brax Saara , Ala‐Risku Timo 
Published: October 2010

PurposeThe purpose of this paper is to introduce a representation scheme that helps original equipment manufacturers and their customers choose between different constellations of visibility‐based service.Design/methodology/approachThe paper uses conceptual modeling and analysis of visibility‐based service infusion using demand‐supply chain representations.FindingsIn the context of service infusion, increased visibility refers to the improved tracking, retention, and sharing of evidence on which service requirements are based. A representation model of three distinct provider‐customer constellations is conceptualize that reflects specific types of visibility: collaborative service supply chain management: condition‐based maintenance as a service: and visibility‐based asset management. The representation is a useful tool for comparing manufacturers' optional service strategies from the perspective of the demand‐supply chain view. The constellations vary in terms of the type of visibility provided by the customer, the provider's use of this visibility, and the potential benefits and costs of transitioning between constellations.Research limitations/implicationsThe demand‐supply chain representations of visibility‐based service infusion are based on conceptual modeling and a literature review. Empirical research is needed to validate the use of the proposed representation for purposes of making comparative choices, and for exploring other purposes in decision making beyond that of comparative choice.Practical implicationsA tool for customers considering the benefits of visibility‐based services, comparative representation of constellations can help providers formulate better strategies for introducing visibility‐based services in a customer relationship.Originality/valueThe study combines supply chain theory with the service infusion literature in a novel way to produce a framework for comparative representation and decision making in visibility‐based service infusion.
The relevance of service in European manufacturing industries
Authors: Lay Gunter , Copani Giacomo , Jäger Angela , Biege Sabine 
Published: October 2010

PurposeCase study findings increasingly indicate that the implementation of service‐based business concepts is becoming a global business trend. The purpose of this paper is to analyze a broad European survey to understand the extent to which service infusion has already deeply affected manufacturing industries and the factors influencing service infusion.Design/methodology/approachData from 3,376 companies participating in the European Manufacturing Survey were included in an evaluation of service offerings and service sales. Multivariate data analyzes were used to develop statistically relevant conclusions regarding service infusion and the factors influencing it.FindingsWhereas, the vast majority of companies surveyed offer services, the turnover generated by services was still low, and the adopted service strategies did not seem fully developed. The most significant determinant of service sales was the breadth of services offered. Other relevant explanatory factors included the characteristics of the type of products sold, whereas the position in the supply chain did not seem to affect service infusion.Research limitations/implicationsUsing large‐scale survey data, this analysis provides a representative picture of service infusion in manufacturing industries and related causal relationships. Further qualitative research should develop interpretations of the relationships found in our quantitative analysis; as such, subsequent quantitative analyzes are necessary.Originality/valueAs most previous studies on service infusion are based on case study reports, the value of this paper comes from its use of a broad empirical database. Thus, the paper supports, confirms, and generalizes previous qualitative findings.
Numerical simulation of channel segregates during alloy solidification using TVD schemes
Authors: Rady Mohamed , Arquis Eric , Gobin Dominique , Goyeau Benoît 
Published: October 2010

PurposeThis paper aims to tackle the problem of thermo‐solutal convection and macrosegregation during ingot solidification of metal alloys. Complex flow structures associated with the development of channels segregate and sharp gradients in the solutal field call for the implementation of accurate methods for numerical modeling of alloy solidification. In particular, the solute transport equation is convection dominated and requires special non‐oscillarity type high‐order schemes to handle the regions of channels segregates.Design/methodology/approachIn the present study, a time‐splitting approach has been adopted to separately handle solute advection and diffusion. This splitting technique allows the application of accurate total variation dimensioning (TVD) schemes for solution of solute advection. Applications of second‐order Lax‐Wendroff TVD SUPERBEE and fifth‐order weighted essentially non‐oscillatory (WENO) schemes are described in the present article. Classical numerical solution of solute transport using hybrid and central‐difference schemes are also employed for the purpose of comparisons. Numerical simulations for solidification of Pb‐18%Sn in a two‐dimensional rectangular cavity have been carried out using different numerical schemes.FindingsNumerical results show the difficulty of obtaining grid‐independent solutions with respect to local details in the region of channels. Grid convergence patterns and numerical uncertainty are found to be dependent on the applied scheme. In general, the first‐order hybrid scheme is diffusive and under predicts the formation of channels. The second‐order central‐difference scheme brings about oscillations with possible non‐physical extremes of solute composition in the region of channel segregates due to sharp gradients in the solutal field. The results obtained using TVD and WENO schemes contain no oscillations and show an excellent capture of channels formation and resolution of the interface between solute‐rich and depleted bands. Different stages of channels formation are followed by analyzing thermo‐solutal convection and macrosegregation at different times during solidification.Research limitations/implicationsAccurate prediction of local variation in the solutal and flow fields in the channels regions requires grid refinement up to scales in the order of microscopic dendrite arm spacing. This imposes limitations in terms of large computational time and applicability of available macroscopic models based on classical volume‐averaging techniques.Practical implicationsThe present study is very useful for numerical simulation of macrosegregation during ingot casting of metal alloys.Originality/valueThe paper provides the methodology and application of TVD schemes to predict channel segregates during columnar solidification of metal alloys. It also demonstrates the limitations of classical schemes for simulation of alloy solidification.
Heat transfer enhancement and pressure drop reduction due to mixed convection between two vertical parallel plates
Authors: Mokheimer Esmail M.A. , Sami S. , Yilbas B.S. 
Published: October 2010

PurposeThis paper's aim is to examine flow and heat transfer through vertical channels between parallel plates, which is of prime importance in the design of cooling systems for electronic equipment such as that of finned cold plates in general, plate‐and‐frame heat exchangers, etc.Design/methodology/approachNumerical and analytical solutions are presented to investigate the heat transfer enhancement and the pressure drop reduction due to buoyancy effects (for buoyancy‐aided flow) for the developing laminar mixed convection in vertical channel between parallel plates in the vicinity of the critical values of the buoyancy parameter (Gr/Re)crt that are obtained analytically. The numerical solutions are presented for a wide range of the buoyancy parameters Gr/Re that cover both of buoyancy‐opposed and buoyancy‐aided flow situations under each of the isothermal boundary conditions under investigation.FindingsBuoyancy parameters greater than the critical values result in building‐up the pressure downstream of the entrance such that the vertical channel might act as a thermal diffuser with possible incipient flow reversal. Locations at which the pressure gradient vanishes and the locations at which the pressure‐buildup starts have been numerically obtained and presented for all the investigated cases.Research limitations/implicationsThe study is limited to the laminar flow situation.Practical implicationsThe results clearly show that for buoyancy‐aided flow, the increase of the buoyancy parameter enhances the heat transfer and reduces the pressure drop across the vertical channel. These findings are very useful for cooling channel or chimney designs.Originality/valueThe study is original and presents new findings, since none of the previous studies reported the conditions for which pressure buildup might take place due to mixed convection in vertical channels between parallel plates.

Properties of steady‐state solutions for a simulated solid rocket motor
Authors: Shusser Michael 
Published: October 2010

PurposeThis paper's aim is to propose a quasi‐steady numerical model of a solid rocket motor that includes the coupling of motor chamber gas dynamics with the composite solid propellant combustion.Design/methodology/approachThe paper considers a model problem of steady‐state burning of a pure monopropellant coupled with a quasi‐steady gas dynamic model of the combustion chamber. In order to simulate the time evolution as the propellant burns back with time, the flow‐field in the chamber, the burning rate and the linear response function parameters are calculated for three port diameters of a simple cylindrical geometry.FindingsIt is shown that the pressure‐coupled linear response function remains approximately constant along the propellant surface but can change very strongly as the chamber pressure rises due to increase in the burn surface.Research limitations/implicationsOnly simplified motor geometry is considered but more realistic geometries can also be analyzed using a similar approach.Originality/valueThis study is the first step in building a comprehensive fully coupled model for numerical simulation of the internal flow‐fields of solid rocket motors. In addition, it demonstrates how to use the steady‐state results to calculate linearized pressure‐coupled response of the propellant.
Chemical reaction and viscous dissipation effects on Darcy‐Forchheimer mixed convection in a fluid saturated porous media
Authors: Mahdy A. , Chamkha A.J. 
Published: October 2010

PurposeThe purpose of this work is to study the flow of mixed convection and mass transfer of a steady laminar boundary layer about an isothermal vertical flat plate embedded in a non‐Darcian porous medium in the presence of chemical reaction and viscous dissipation effects.Design/methodology/approachThe governing partial differential equations are converted into ordinary differential equations by similarity transformation, which are solved numerically by employing the fourth‐order Runge‐Kutta integration scheme with Newton‐Raphson shooting technique.FindingsIt was found that the local Nusselt number was predicted to decrease as either of the chemical reaction parameter or the Eckert number increased. On the other hand, the local Sherwood number was predicted to increase as a result of increasing either of the chemical reaction parameter or the Eckert number. Also, in the absence of viscous dissipation, both the local Nusselt and Sherwood numbers increased as the mixed convection increased.Originality/valueThe paper illustrates chemical reaction and viscous dissipation effects on Darcy‐Forchheimer mixed convection in a fluid saturated porous media.
Parametric analysis of entropy generation due to laminar developing mixed convection between differentially heated isothermal vertical parallel plates
Authors: Mokheimer Esmail M.A. 
Published: October 2010

PurposeThe aim of this article is to present the results of a parametric analysis of the entropy generation due to mixed convection in the entry‐developing region between two differentially heated isothermal vertical plates.Design/methodology/approachThe entropy generation was estimated via a numerical solution of the mass, momentum and energy conservation equations governing the flow and heat transfer in the vertical channel between the two parallel plates. The resultant temperature and velocity profiles were used to estimate the entropy generation and other heat transfer parameters over a wide range of the operating parameters. The investigated parameters include the buoyancy parameter (Gr/Re), Eckert number (Ec), Reynolds number (Re), Prandtl number (Pr) and the ratio of the dimensionless temperature of the two plates (θT).FindingsThe optimum values of the buoyancy parameter (Gr/Re) optimum at which the entropy generation assumes its minimum for the problem under consideration have been obtained numerically and presented over a wide range of the other operating parameters. The effect of the other operating parameters on the entropy generation is presented and discussed as well.Research limitations/implicationsThe results of this investigation are limited to the geometry of vertical channel parallel plates under isothermal boundary conditions. However, the concept of minimization of entropy generation via controlling the buoyancy parameter is applicable for any other geometry under any other thermal boundary conditions.Practical implicationsThe results presented in this paper can be used for optimum designs of heat transfer equipment based on the principle of entropy generation minimization with particular focus on the optimum design of plate and frame heat exchanger and the optimization of electronic packages and stacked packaging of laminar‐convection‐cooled printed circuits.Originality/valueThis paper introduces the entropy generation minimization via controlling the operating parameters and clearly identifies the optimum buoyancy parameter (Gr/Re) at which entropy generation assumes its minimum under different operating conditions.
Exploring the supply of pirate software for mobile devices
Authors: Goode Sigi 
Published: October 2010

PurposeSoftware piracy is an ongoing problem for software producers. At the same time, mobile devices such as personal digital assistants and smart phones are increasing in popularity. This paper seeks to examine the supply of pirate software for mobile devices, against a backdrop of conventional desktop piracy theory.Design/methodology/approachUsing a novel data set of pirate software releases, the paper reviews 18,000 entries from a pirate software database to examine the type and origin of this software.FindingsThe paper finds that more popular platforms are not necessarily subject to greater levels of software piracy. For mobile devices, productivity software was more popular than game software. Many piracy groups were involved, but only four groups were responsible for over half of all releases. Some popular devices, such as the Blackberry and Apple iPhone, showed little to no piracy levels.Research limitations/implicationsAs with empirical research into any criminal or deviant behaviour, there may be intention to deceive. The findings regarding device popularity and availability of pirate software have implications for demand‐side research.Practical implicationsThe findings provide insights for business managers and information security professionals in the telecommunications and mobile applications industries.Originality/valuePrior research work has focused on software for desktop computers. This study contributes by being some of the first published work on piracy for mobile devices. The work is also original in that most prior research has focused on the demand for pirate software. This paper provides insight into the supply of this software.
