Show me the money
Authors: Maklan Stan , Peppard Joe , Klaus Philipp 
Published: April 2015

Purpose
– The purpose of this paper is to examine the conundrum between the increasingly importance of investments in new information technologies (IT) on marketing practice and marketing scholars continuing to question the profitability of IT-led marketing initiatives.

Design/methodology/approach
– Systematic reviews of the relevant literature on the financial and market return of customer relationship management (CRM) investments from both Marketing and Information Systems (IS) literature were conducted.

Findings
– Findings suggest that, while both IS and Marketing scholars try to determine what generates returns on CRM investment, the IS community has a more complete conceptualisation as to how these returns are realised. A broader epistemological framework, better suited to observing how organisations benefit from IT-led management initiatives, enables a more comprehensive assessment of CRM investment.

Research limitations/implications
– Supplementing the methods used by Marketing scholars with those frequently used in IS research would likely improve the assessment of IT-led Marketing investments and the resultant prescriptions for Marketing practitioners.

Practical implications
– Failure to assess accurately the return from IT-led Marketing investments hinders managers’ ability to manage them for maximum performance improvements, all the more important now that organisations are preparing for large-scale investments in big data and social media strategies.

Originality/value
– This paper is the first to illustrate how a combination of Marketing and IS scholarship can assist Marketing research and practice.
Oblique stagnation flow of Jeffery fluid over a stretching convective surface
Authors: Mehmood R , Nadeem Dr. Sohail , Akbar Noreen 
Published: April 2015

Purpose
– The present critical analysis has been performed to explore the steady stagnation point flow of Jeffery fluid toward a stretching surface, in the presence of convective boundary conditions. It is assumed that the fluid strikes the wall obliquely. The governing non-linear partial differential equations for the flow field are converted to ordinary differential equations by using suitable similarity transformations. Optimal homotopy analysis method (OHAM) is operated to deal the resulting ordinary differential equations. OHAM is found to be extremely effective analytical technique to obtain convergent series solutions of highly non-linear differential equations. Graphically, non-dimensional velocities and temperature profile are expressed. Numerical values of skin friction coefficients and heat flux are computed. The comparison of results from this paper with the previous existing literature authorizes the precise accuracy of the OHAM for the limited case. The paper aims to discuss these issues.

Authors: Aly Abdelraheem Mahmoud 
Published: April 2015

Purpose
– Modeling of multi-phase flows for Rayleigh-Taylor instability and natural convection in a square cavity has been investigated using an incompressible smoothed particle hydrodynamics (ISPH) technique. In this technique, incompressibility is enforced by using SPH projection method and a stabilized incompressible SPH method by relaxing the density invariance condition is applied. The paper aims to discuss these issues.

Design/methodology/approach
– The Rayleigh-Taylor instability is introduced in two and three phases by using ISPH method. The author simulated natural convection in a square/cubic cavity using ISPH method in two and three dimensions. The solutions represented in temperature, vertical velocity and horizontal velocity have been studied with different values of Rayleigh number Ra parameter (103=Ra=105). In addition, characteristic based scheme in Finite Element Method is introduced for modeling the natural convection in a square cavity.

Findings
– The results for Rayleigh-Taylor instability and natural convection flow had been compared with the previous researches.

Originality/value
– Modeling of multi-phase flows for Rayleigh-Taylor instability and natural convection in a square cavity has been investigated using an ISPH technique. In ISPH method, incompressibility is enforced by using SPH projection method and a stabilized incompressible SPH method by relaxing the density invariance condition is introduced. The Rayleigh-Taylor instability is introduced in two and three phases by using ISPH method.

Authors: Baïri Abderrahmane , García de María Juan Mario , Alilat Nacim , Laraqi Najib , Bauzin Jean-Gabriel 
Published: April 2015

Purpose
– The purpose of this paper is to propose correlations between Nusselt and Rayleigh numbers for the case of inclined and closed air-filled hemispherical cavities. The disk of such cavities is subjected to a constant heat flux. The study covers a wide range of Rayleigh numbers from 5×107 to 2.55×1012.

Design/methodology/approach
– Correlations are obtained from numerical approach validated by experimental measurements on some configurations, valid for several angles of inclination of the cavity between 0° (horizontal disk) and 90° (vertical disk) in steps of 15°.

Findings
– The statistical analysis of a large number of calculations leads to reliable results covering laminar, transitional and turbulent natural convection heat transfer zones.

Practical implications
– The proposed correlations provide solutions for applications in several fields of engineering such as solar energy, aerospace, building, safety and security.

Originality/value
– The new relations proposed are the first published for high Rayleigh numbers for this type of geometry. They supplement the knowledge of natural convection in hemispherical inclined cavities and constitute a useful tool for application in various engineering areas as solar energy (thermal collector, still, pyranometer, albedometer, pyrgeometer), aerospace (embarked electronics), building, safety and security (controlling and recording sensors).
Effects of gradient density on effective heat capacity of charring ablative material for re-entry vehicles
Authors: Li Weijie , Huang Haiming , Yu Hailing , Xu Xiaoliang 
Published: April 2015

Purpose
– The effective heat capacity is a key index to estimate the thermal protection performance of charring ablative materials in reentry vehicles subjected to aerodynamic heat loads. The purpose of this paper is to investigate the effects of gradient density on the effective heat capacity.

Design/methodology/approach
– Based on the Fourier law and the pyrolysis interface model, the authors establish the governing equations for the transient heat conduction with variable density, and then simulate one-dimensional transient thermal behavior of a homogeneous and three types of non-homogeneous charring ablative material in reentry capsules by using the implicit numerical method.

Findings
– The moving rate of pyrolysis interface and the surface temperature of charring ablative material depend on not only the surface heating history, but also the gradient density. And the gradient density can improve the insulation performance of charring materials, e.g. the effective heat capacity in the bilinear design is larger than that in the homogeneous design under a given heat flux condition.

Originality/value
– This study will help the design of the thermal protection system in reentry vehicles.
Rule-breaking and legitimacy: a failure of artful navigation?
Authors: Warren Lorraine , Smith Robert 
Published: April 2015

Purpose– The purpose of this paper is to critically examine the tension between rule-breaking and legitimacy for entrepreneurs, who are expected to challenge and change social or business norms. In doing so, they may be presented as heroes in the media, or alternatively, are cast out as villains with attendant negative press with consequent loss of legitimacy.Design/methodology/approach– Through secondary data methods, the paper analyses the case of Vance Miller, an entrepreneur from the North of England who has achieved economic success amid reports of alleged criminality and poor ethical behaviour. Thus he spans rule-breaking and legitimacy.Findings– The paper illustrates how rule-breaking directed towards demonstrable entrepreneurial achievement does not always result in media legitimacy. Miller’s storyline both chimes with and clashes with the discourse of the enterprise culture, providing a cautionary note for aspirant entrepreneurs.Research limitations/implications– The hero-villain paradox remains relatively unexplored in the media, and thus further qualitative research is required, particularly for aspirant entrepreneurs with controversial or criminal backgrounds.Practical implications– Entrepreneurs should question carefully the extent and potential consequences of rule breaking in regard to legitimacy.Social implications– The paper highlights and indeed questions the role of the media in their representations of entrepreneurship, and challenges the valorisation of rule-breaking behaviour by entrepreneurs.Originality/value– The paper makes a distinctive contribution to the literature by examining the relation between rule-breaking and legitimacy for an entrepreneur who is represented negatively in the media, yet remains successful, counter to the heroic stereotype.
The legitimacy of entrepreneurial mentoring
Authors: McKevitt David , Marshall Donna 
Published: April 2015

Purpose– The purpose of this paper is to present findings from longitudinal case studies of small firm mentoring relationships in Ireland. The rationale is to explore the gaps between the theory and practice of small firm mentoring.Design/methodology/approach– The paper uses a comparative case study design involving interviews, observation and secondary sources of evidence including business plans.Findings– In contrast to the literature the paper extends the role of mentors in the small firm context as offering direct and indirect support, which reduces uncertainty in order to increase legitimacy of the business entity.Research limitations/implications– The cases highlight a conflict between the broad theoretical scope of the mentor process vs a narrow role assumed by best practice.Practical implications– The research presents an opportunity to enhance the pragmatic vs paternalistic perspective of small firm mentoring. The authors argue that for mentoring theory to be useful then a mentor’s role-set in small firms may be wider and should be more direct than mentors in large corporations.Originality/value– The emergent theoretical framework combines organisational learning and decision-making theories. The paper contributes to the theoretical development of mentoring by extending the range and defining the role of mentors in the context of small firms.
Protecting organizational knowledge: a structured literature review
Authors: Manhart Markus , Thalmann Stefan 
Published: April 2015

Purpose– The purpose of this paper is to investigate pertinent knowledge protection literature. At the same time, however, knowledge protection is often a neglected or underdeveloped area. This is all the more concerning as knowledge protection plays an essential part in preserving an organization’s competitive advantage. Despite the recognition of this issue by scholars, the knowledge management literature has so far tended to concentrate on the facilitation of knowledge sharing rather than on knowledge protection.Design/methodology/approach– In this paper, the authors present the results of a structured literature review undertaken to investigate the current state of research on knowledge protection. The paper identifies core domains in knowledge protection literature, discusses theoretical perspectives and research methods, sheds light on the role of the information technology (IT) artefact in knowledge protection research and develops a portfolio of knowledge protection measures.Findings– In this paper, 48 papers were analyzed by taking five analytical dimensions into account: research domains, research methods and models, the role of the IT artefact, theoretical views and measures to enforce knowledge protection. Based on the discussion of the results, promising avenues for further research were identified and a research agenda was proposed. The authors argued for more research on the protection of tacit knowledge, more in-depth empirical investigations, more research on IT support and a stronger consideration of theories in knowledge protection research, as well as research on how organizations could build a strategy of knowledge protection.Research limitations/implications– Tacit knowledge, as well as informal alliances or (social) networks, is under-researched so far. Knowledge protection phenomena need to be investigated in depth to test the assumptions stated in many conceptual papers. IT artefacts should be developed and evaluated. More theory-based research and overarching frameworks or strategies for knowledge protection need to be developed.Practical implications– In this paper, a portfolio of knowledge protection measures was developed, which might be of particular interest for practitioners. Further, the paper provides a good overview of the current state of practice regarding knowledge protection.Originality/value– So far, there is no structured literature available focussing on the topic of knowledge protection.
Mechanisms to motivate knowledge sharing: integrating the reward systems and social network perspectives
Authors: Lin Sheng-Wei , Lo Louis Yi-Shih 
Published: April 2015

Purpose– The purpose of this study is to develop a theoretical model that integrates two different mechanisms to explain knowledge sharing. First, adapted from traditional reward systems, the calculative-based mechanism (CBM) serves as the benchmark. Second, the relational-based mechanism (RBM) plays a complementary role. RBM is founded on social interaction and consists of two social network constructs: relational deposits (i.e. network and valued network centralities) and withdrawals (i.e. network and valued network densities).Design/methodology/approach– This study collected survey data in collaboration with a health-care organization. The data collected from 180 respondents were tested against the research model using a partial least squares analysis.Findings– This study found the CBM to be beneficial for knowledge sharing. The findings support the RBM prediction of a positive relationship between the deposit construct and knowledge sharing, but fail to support the RBM prediction on the withdrawal construct. The RBM explained about 15 per cent more of the variance than the CBM. In addition, the withdrawal construct of the RBM predicts respondents’ beliefs in reciprocal obligation.Research limitations/implications– RBM does not as strongly associate with economic benefits as the CBM, but it still plays a noteworthy role in increasing the possibility of an individual knowledge sharing.Originality/value– The study is the first to propose the concepts of relational deposits and withdrawals. The authors use a roster-based sociometric approach to collect the social network data and to benchmark the effect of RBM with that of CBM on individual knowledge sharing and his/her beliefs in reciprocal obligation.
Positioning organisational culture in knowledge management research
Authors: Al Saifi Said Abdullah 
Published: April 2015

Purpose– The purpose of this paper is to propose a conceptual model for understanding the impact of organisational culture on knowledge management processes and their link with organisational performance. It is suggested that organisational culture should be assessed as a multi-level construct comprising artefacts, espoused beliefs and values and underlying assumptions. A holistic view of organisational culture and knowledge management processes, and their link with organisational performance, is presented.Design/methodology/approach– A comprehensive review of previous literature was undertaken in the development of the conceptual model. Taken together, the literature and the proposed model reveal possible relationships between organisational culture, knowledge management processes and organisational performance.Findings– Potential implications of organisational culture levels for the creation, sharing and application of knowledge are elaborated. In addition, the paper offers possible new insight into the impact of organisational culture on various knowledge management processes and their link with organisational performance.Research limitations/implications– A number of possible relationships between organisational culture factors, knowledge management processes and their link with organisational performance were used to examine such relationships.Practical implications– The research model highlights the multi-level components of organisational culture. These are: the artefacts, the espoused beliefs and values and the underlying assumptions. Through a conceptualisation of the relationships between organisational culture, knowledge management processes and organisational performance, the study provides practical guidance for practitioners during the implementation of knowledge management processes.Originality/value– The focus of previous research on knowledge management has been on understanding organisational culture from the limited perspective of promoting knowledge creation and sharing. This paper proposes a more comprehensive approach to understanding organisational culture in that it draws on artefacts, espoused beliefs and values and underlying assumptions, and reveals their impact on the creation, sharing and application of knowledge which can affect the overall organisational performance.
Deterrents to knowledge-sharing in the pharmaceutical industry: a case study
Authors: Qureshi Athar Mahmood Ahmed , Evans Nina 
Published: April 2015

Purpose– This study aims to explore deterrents to knowledge-sharing in pharmaceutical manufacturing. Effective knowledge-sharing is fundamental to stimulation of the process of knowledge absorption. The limited proximal communication between the employees in the pharmaceutical industry stifles their knowledge-sharing behaviour significantly.Design/methodology/approach– A cross-sectional case study, consisting of semi-structured interviews with managers and scientists, was conducted in a multinational pharmaceutical company in Australia. Respondents were asked to answer questions regarding their current knowledge-sharing practices and to identify organisational deterrents to knowledge-sharing. The data were condensed into themes according to the thematic analysis method.Findings– The pharmaceutical industry is extensively regulated and its excessive competitiveness is cultivating organisational reticence towards the development of a knowledge-sharing culture. Nine categories of deterrents to intra- (within) and inter-organisational (between organisations) knowledge-sharing have been identified. These categories include high cost of sharing knowledge, information technology limitations, knowledge-hiding, lack of socialisation, lack of trust culture, non-educational mindset, organisational politics, poor leadership and time pressure.Research limitations/implications– The population of this study consists of managers and practitioners working for a pharmaceutical company. Hence, the generalisability of the findings to other health-care settings is unknown.Practical implications– The findings have implications for leaders and managers who should be aware of these professional diversities, instigators as well as the ripple effects of limited knowledge-sharing to guide the organisation towards developing an optimal knowledge-sharing culture.Originality/value– A focussed investigation of knowledge-sharing behaviour within the pharmaceutical industry in Australia, considering the pressure applied to this industry over the past decade. This case study specifically focusses on the diversity of deterrents to knowledge-sharing in the pharmaceutical manufacturing industry.
