Non-traveling wave solutions for the (2+1)-D Caudrey-Dodd-Gibbon-Kotera-Sawada equation
Authors: Kang Xiao-rong , Daquan Xian , Dai Zhengde 
Published: April 2015

Purpose
– The purpose of this paper is to find new non-traveling wave solutions and study its localized structure of Caudrey-Dodd-Gibbon-Kotera-Sawada (CDGKS) equation.

Design/methodology/approach
– The authors apply the Lie group method twice and combine with the Exp-function method and Riccati equation mapping method to the (2+1)-dimensional CDGKS equation.

Findings
– The authors have obtained some new non-traveling wave solutions with two arbitrary functions of time variable.

Research limitations/implications
– As non-linear evolution equations is characterized by rich dynamical behavior, the authors just found some of them and others still to be found.

Originality/value
– These results may help the authors to investigate some new localized structure and the interaction of waves in high-dimensional models. The new non-traveling wave solutions with two arbitrary functions of time variable are obtained for CDGKS equation using Lie group approach twice and combining with the Exp-function method and Riccati equation mapping method by the aid of Maple.

Published: April 2015

Purpose
– The purpose of this paper is to improve the volume-averaged models for free convection flow in porous media.

Design/methodology/approach
– A pore scale simulation is conducted against which an independent volume-averaged solver is fine-tuned.

Findings
– Micro and macro scale results can merge if proper choice of local thermal non-equilibrium and thermal dispersion models are selected. This depends on the range of Ra values investigated.

Originality/value
– This is the first time a work like this is published in the literature.
Joules and Newtonian heating effects on stagnation point flow over a stretching surface by means of genetic algorithm and Nelder-Mead method
Authors: Nawaz M. , Zeeshan A , Ellahi R , Abbasbandy S , Rashidi Saman 
Published: April 2015

Purpose
– The purpose of this paper is to study the Joules heating effects on stagnation point flow of Newtonian and non-Newtonian fluids over a stretching cylinder by means of genetic algorithm (GA). The main emphasis is to find the analytical and numerical solutions for the said mathematical model. The work undertaken is a blend of numerical and analytical studies. Effects of active parameters such as: Hartmann number, Prandtl number, Eckert number, Nusselt number, Skin friction and dimensionless fluids parameters on the flow and heat transfer characteristics have been examined by graphs and tables. Compression is also made with the existing benchmark results.

Design/methodology/approach
– Analytical solutions of non-linear coupled equations are developed by optimal homotopy analysis method (OHAM). A very effective and higher order numerical scheme hybrid GA and Nelder-Mead optimization Algorithms are used for numerical investigations.

Findings
– An excellent agreement with the existing results in limiting sense is noted. It is observed that the radial velocity is an increasing function of dimensionless material parameters α
1, α
2 and β. Temperature increases by increasing the values of M, Pr, Ec and γ. Non-Newtonian parameter β has similar effects on skin friction coefficient and Nusselt number. The wall heat transfer rate is a decreasing function of A and ß whereas it increases by increasing conjugate parameter γ.

Originality/value
– The problem under consideration has been widely studied by many investigators due to its importance and engineering applications. But most of the studies as the authors have documented are for Newtonian or viscous fluids. But no such analysis is available in the literature which can describe the Joules heating effects on stagnation point flow of Newtonian and non-Newtonian fluids over a stretching cylinder by means of GA.
Transient free convection within air-filled hemispherical enclosures. Nu-Ra-Fo relationships for isothermal and inclined disk with dome oriented upwards
Authors: Baïri Abderrahmane 
Published: April 2015

Purpose
– Nusselt-Rayleigh-Fourier type correlations are proposed to quantify the temporal evolution of convective heat transfer occurring within air-filled hemispherical enclosures whose disk, initially at ambient temperature, is suddenly maintained at a higher temperature. The temperature difference imposed between this hot wall and the isothermal cold dome involves Rayleigh number varying between 104 and 2.55×1012. Depending on the application, the disk can be inclined with respect to the horizontal plane by an angle varying between 0° (horizontal disk) and 90° (vertical disk) in steps of 15°. The paper aims to discuss these issues.

Design/methodology/approach
– The results are obtained by means of a numerical approach based on the finite volume method. The proposed correlations linked to the steady state Nusselt-Rayleigh internships recently published, concerning the same inclination angle and Rayleigh ranges.

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 relationships can be applied in several engineering fields such as nuclear technology, solar energy, security and safety electronics, building, domotics or aeronautics.

Originality/value
– The new relationships proposed in this paper provide important information on the evolution of convective heat transfer during the transient regime.

Authors: Hayat Tasawar , Ashraf Bilal , Shehzad Sabir Ali , Abouelmagd Elbaz 
Published: April 2015

Purpose
– The purpose of this paper is to analyze the Eyring Powell fluid over an exponentially stretching surface. Heat and mass transfer effects are taken into account with nanoparticles.

Design/methodology/approach
– Appropriate transformations are employed to reduce the boundary layer partial differential equations into ordinary differential equations. Series solutions of the problem are obtained and impacts of physical parameters on the velocities, temperature and concentration profiles are discussed.

Findings
– Numerical values of local Nusselt and Sherwood numbers for all the involved physical parameters are computed and analyzed. A comparative study between the present and previous results is made in a limiting sense. Local Nusselt number −′(0) increases by increasing ε, Pr, λ and N while it decreases for δ, N_{t{, N_{b} and Sc.

Originality/value
– This analysis has not been discussed in the literature yet.
Meeting the entrepreneurial learning needs of professional athletes in career transition
Authors: Kenny Breda 
Published: April 2015

Purpose– A career at the professional, elite level in sports does not last forever. One way or another, the day comes when players have to hang up their boots and move on, but to what? Some stay in the sport as managers or coaches, become broadcast announcers, or use their name recognition to pitch a product. However, for many their future opportunities lie in entrepreneurship. The purpose of this paper is to explore the concept of the entrepreneurial learning needs of professional rugby players preparing for a career transition and asks the following questions: What are the specific needs of professional athletes in relation to entrepreneurial learning?, and, what are the key elements of designing an entrepreneurship programme to meet these needs?Design/methodology/approach– The author adopted an interpretivist philosophical standpoint for this research, with an inductive research approach to explore various components of a tailored entrepreneurship training programme called the “Certificate in Enterprise Potential” (CEP) using the process of emergent inquiry. This programme was designed specifically for professional rugby athletes in Ireland. In gathering the data for the case study, the author pursued established principles of data collection, and used multiple sources of evidence.Findings– The findings provide evidence of the entrepreneurial learning needs of professional athletes in career transition and identifies the key elements to be considered when designing an entrepreneurship programme to meet these needs. The findings are presented under the headings context, objectives and outcomes, audience, content, pedagogy, assessment and evaluation.Research limitations/implications– There are multiple implications from this study. For entrepreneurship educators, the various components of designing a tailored entrepreneurship programme for professional athletes are identified and outlined. For researchers, it opens the door for research with other sports people from different contexts. For professional athletes and professionals working with athletes, it provides evidence of a non-athletic and an entrepreneurial career transition model that builds on the player’s social identity, social networks and taps into an existing HEI entrepreneurship ecosystem. The research was confined to a single case study for a specific target audience and needs replication with other cohorts in order to reduce the chance of these findings being unique to one single case.Originality/value– This paper focuses on the career transition and mid-career aspect of entrepreneurship education and in particular the career transition needs of the professional athletes. These findings provide a deeper understanding of mid-career entrepreneurship education, specifically in the contexts of professional athletes and HEI’s. Many athletes are forced to end their sporting careers early and with little hope of a meaningful or alternative long-term career options. This paper goes some way in addressing this concern.
Entrepreneurs’ network evolution – the relevance of cognitive social capital
Authors: Jonsson Sara 
Published: April 2015

Purpose– The purpose of this paper is to investigate entrepreneurs’ network evolution in the start-up phase.Design/methodology/approach– Based on the case studies of six fashion start-up firms, this study uses a three-dimensional perspective on social capital (structural, relational, cognitive) to investigate entrepreneurs’ network evolution (i.e. initiation of new relationships) in the start-up phase so as to acquire resources and support for firms’ goals. The study focuses particularly on the understudied cognitive dimension of social capital. The fashion industry provides a relevant research setting because it is characterised by changes in demand, which generate opportunities for entrepreneurship.Findings– The findings show that the display of cognitive attributes is important for the creation of structural social capital (the establishment of new relationships). The findings also indicate that relationships initiated based on the cognitive dimension have a high probability of developing into embedded relationships, thereby becoming high in the relational dimension and providing access to private information containing referrals to other actors. Thus, these relationships also promote the continued development of the structural dimension.Originality/value– The findings imply that the entrepreneurs’ sets of cognitive attributes constitute an important asset in the creation of social capital. They also point to the importance of signalling these values to potential resource holders. Relationships initiated through the display of cognitive attributes can provide resources without requiring immediate economic remuneration.
Immigrant and second-generation Turkish entrepreneurs in Melbourne Australia
Authors: Soydas Yasemin , Aleti Torgeir 
Published: April 2015

Purpose– The purpose of this paper is to examine the key differences between first- and second-generation immigrant entrepreneurs in their path to entrepreneurship. The aim of the study is to better understand entrepreneurial motivations amongst immigrants by comparing first- and second-generation entrepreneurs in their motivation for business entry, reliance on co-ethnic market, use of social and financial capital, business planning and marketing practices.Design/methodology/approach– Using an interpretivist approach and a qualitative design, this study comprises 20 in-depth interviews with first- and second-generation Turkish entrepreneurs (TEs) in Melbourne, Australia. Turks in Australia were chosen because of their high level of entrepreneurial activity. In order to uncover deep-seeded motivations, participants were interviewed in a face-to-face format guided by a semi-structured interview guide.Findings– The second-generation TEs were distinctively different from their first-generation counterparts in motivation for business entry, business establishment and use of ethnicity. The analysis shows that although the generations differ in their approach to business establishment, they both appear to be drawn to entrepreneurship based on “pull factors”. This is in contrast with previous literature suggesting that first-generation immigrant entrepreneurs were motivated by “push factors”.Originality/value– This paper suggests that both first- and second-generation immigrant entrepreneurs are “pulled” into entrepreneurship voluntarily. While the first-generation entrepreneurs seem to be motivated/pulled by financial reasons, the second generation are motivated by opportunity recognition, status and ambition. Nevertheless, a lack of trust in government support agency is found within both generations. Thus, outreach activities towards entrepreneurial immigrant communities may have positive effects for the economy as well as in the integration of ethnic enclaves.
Knowledge creation and utilization in project teams
Authors: Oluikpe Paul Ihuoma 
Published: April 2015

Purpose– The purpose of this paper is to explore the knowledge processes that interplay in the social construction and appropriation of knowledge and to test these constructs empirically in project teams.Design/methodology/approach– Literature research and quantitative survey were used. The research identified project success, faster completion times, operational efficiency, innovation and generation of new knowledge as dominating project management expectations in the past ten years. It studied how these projects construct and appropriate knowledge within project teams to achieve these five objectives. Using a quantitative approach, data were sought from 1,000 respondents out of a population of 10,000 from 11 project management areas in eight world regions to test the conceptual model in real-world scenarios. The data gathered were analyzed using quantitative analysis tools and techniques such as reliability, correlation and regression.Findings– There is a lingering difficulty within organizations on how to translate tacit knowledge into action. The transfer and utilization of tacit knowledge was shown to be embedded and nested within relationships. Innovation in projects was found to be mostly linked to replication and codification of knowledge (explicit dimension) as opposed to interpretation and assimilation (tacit dimension). Arriving at a mutual interpretation of project details and requirements does not depend on canonical (formal documentation) methods but mostly on non-canonical (informal) and relational processes embedded within the team.Originality/value– This work studies, in empirical and geographical detail, the social interplay of knowledge and provided evidence relative to the appropriation of knowledge in the project organizational form, which can be extrapolated to wider contexts. The work scoped the inter-relational nature of knowledge and provided further evidence on the nebulous nature of tacit/intangible knowledge. It also proved further that organizations mostly rely on explicit knowledge to drive organizational results, as it is easily actionable and measurable.
Facilitating tacit knowledge transfer: routine compatibility, trustworthiness, and integration in M & As
Authors: Ranucci Rebecca Ann , Souder David 
Published: April 2015

Purpose– This paper aims to theorize how tacit knowledge influences implementation success in mergers and acquisitions (M & As), and contrasts this with explicit knowledge. Tacit knowledge can be a source of sustained competitive advantage because its lack of codifiability precludes easy appropriation by competitors. However, such non-codifiability also makes it difficult to transfer knowledge within a firm. M & As exemplify this challenge because they are often motivated by opportunities for transferring knowledge. With differing demands for tacit and explicit knowledge across departments (Sales and Operations), the empirical results demonstrate how tacit routine compatibility affects implementation outcomes in different functions.Design/methodology/approach– This research draws from a survey of 86 M & A implementation processes between 1996 and 2002, using seemingly unrelated regression to analyze the predictions.Findings– There is strong empirical support that tacit routine compatibility leads to success in sales but not operations and further support for the differential moderating roles of trustworthiness and integration.Practical implications– Managers should make implementation choices based on the type of knowledge being transferred and where that knowledge will reside post-integration. Routine compatibility, trustworthiness and integration facilitate knowledge transfer in M & As – but only if applied in the right combinations for the context.Originality/value– The type of knowledge is a critical distinction for the value of M & A implementation. Furthermore, despite integration receiving significant attention in this literature, trustworthiness, not integration, facilitates successful tacit knowledge transfer in M & As.
The construct of absorptive capacity in knowledge management and intellectual capital research: content and text analyses
Authors: Mariano Stefania , Walter Christian 
Published: April 2015

Purpose– The purpose of this paper is to provide a holistic picture of how and to what extent Cohen and Levinthal’s (1990) seminal article on absorptive capacity was used in knowledge management (KM) and intellectual capital (IC) research from 1990 to 2013.Design/methodology/approach– In this paper, 186 articles extracted from eight KM and IC journals were reviewed by conducting both content and text analyses. To facilitate research comparison, content analysis followed the method used by Robertset al.(2012) and thus was based on categories, conceptualizations, levels of analysis and, additionally, temporal evolution of absorptive capacity from 1990 to 2013 was looked at. Text analysis was performed to identify major research themes developing the absorptive capacity construct.Findings– Finding showed that absorptive capacity was largely underdeveloped in the KM and IC fields. KM, knowledge transfer and innovation were the top three research areas investigating absorptive capacity in the KM and IC fields.Research limitations/implications– This study had limitations related to time frame, covering a period from April 1990 to November 2013, and accessibility of articles due to specific restrictions in journal subscriptions.Originality/value– This paper is a first attempt to review absorptive capacity in KM and IC research. It represented a primary reference for those interested to research absorptive capacity in the KM and IC fields.
The nature and development of liminality competence
Authors: Borg Elisabeth , Soderlund Jonas 
Published: April 2015

Purpose– This paper aims to present findings from an interpretative study documenting how mobile project workers develop their conceptions of work performed in liminal (in-between) positions. The overall purpose of the paper is to elucidate how people in time-limited and ambiguous work positions develop competences to manage their dynamic work conditions.Design/methodology/approach– This research relies on two narratives of mobile project workers drawn from a larger longitudinal study. The empirical material includes diaries and multiple interviews. The analysis takes a narrative approach and identifies how and when the mobile project workers enhance their level of liminality competence.Findings– Three processes were identified as significant in developing higher liminality competence: understanding the value of in-betweenness, embracing the role as an inside-outsider and translating the liminal experience through reflexivity.Practical implications– The paper demonstrates the need for employers to support individuals in passing through the three processes and to support thoughtful mobility across different project settings to improve the liminality competence of their employees.Originality/value– In the dual ambition of offering insights based on interpretative research on competence and putting greater emphasis on people working in in-between positions, this study enhances the understanding of how individuals develop their conceptions of work in general, and their conceptions of liminality at work in particular.

Published: April 2015

Purpose– The purpose of this paper was to analyse text mining (TM) literature indexed in the Web of Science (WoS) under the “Information Science Library Science” subcategory. More specifically, it analyses the chronological growth of TM literature, and the major countries, institutions, departments and individuals contributing to TM literature. Collaboration in TM research is also analysed.Design/methodology/approach– Bibliographic and citation data required for this research were retrieved from the WoS database. TM being a multidisciplinary field, the search was restricted to “Information Science Library Science” subcategory in the WoS. A comprehensive query statement covering all synonyms of “text mining” was prepared using the Boolean operator “OR”. Microsoft Excel and HistCite software were used for data analysis. Pajek and VoSviewer were used for data visualization.Findings– It was found that USA is the major producer of TM research literature, and the highest number of papers were published in theJournal of The American Medical Informatics. Columbia University ranked first both in number of articles and citations received in the top ten institutes publishing TM literature. It was also observed that six of the top ten subdivisions of institutions are either from medicine or medical informatics or biomedical information. H.C. Chen and C. Friedman were seen to be the most prolific authors.Research limitations/implications– The paper analyses articles on TM published during 1999-2013 in WoS under the subcategory Information Science Library Science’.Originality/value– The paper is based on empirical data exclusively gathered for this research.
