Authors: Tola Ceyhun , Nikbay Melike 
Published: November 2018

Purpose
This study aims to determine the relationship between sectional geometric parameters of a slotted solid rocket propellant on structural integrity and internal ballistic performance of a rocket motor by using response surface method.

Design/methodology/approach
Zero-dimensional (0D) ballistic solver is developed and validated to determine the effects of sectional geometric parameters on internal ballistic performance of a rocket motor. Additionally, effects of these parameters on structural strength of the system are examined by performing linear viscoelastic finite element analysis under plane strain assumption. Results of the 0D internal ballistic analyses are used as an input to the structural analysis.

Findings
Different response surfaces are constructed to represent the characteristic variation of solid propellant’s structural strength and internal ballistic performance with respect to design variables.

Originality/value
Coupled analysis methodology in terms of structural strength and internal ballistic performance presented in this work facilitates many designers who are working on solid rocket motor development. This study represents graphical results summarizing effects of sectional parameters of a slotted grain on both internal ballistic performance and structural strength results. Additionally, graphical results summarizing the effects of sectional parameters on structural strength and internal ballistic performance provide useful information for researchers that lessens design period. Finally, validations presented in this work can also be used as a benchmark reference for different studies.

Published: November 2018

PurposeThe purpose of this paper is to investigate the effects of audit client importance on future bank risk and systemic risk in US-listed commercial banks.Design/methodology/approachThe authors use archival research method.FindingsThe authors mainly find that client importance is negatively related with future bank-specific crash risk and distress risk, and also with sector-wide systemic crash risk and systemic distress risk in the future. The authors also report some evidence that these relations become more pronounced during the crisis period than during the non-crisis period. Moreover, the effect of client importance on systemic risk is found to strengthen in banks audited by Big-N auditors, by auditors without clients who restate earnings, and by auditors with more industry expertise.Research limitations/implicationsThese findings contribute to the auditing and systemic risk literature.Practical implicationsThis study has implications for regulating the banking industry.Originality/valueThis study provides original evidence on how client importance affects bank-specific risk and systemic risk of the banking industry.
Preaching to the middle of the road
Authors: Armstrong Soule Catherine Anne , Sekhon Tejvir 
Published: November 2018

PurposeThe purpose of this paper is to explore strategic differences in marketing communication tactics for vegan and humane meat brands.Design/methodology/approachContent analysis was used to categorize the types of persuasive appeals used on the packaging of vegan and humane meat brands.FindingsHumane meat brands use animal welfare and environmental appeals more often whereas vegan brands use taste appeals more frequently.Social implicationsMarketers’ communication strategies for alternatives to traditional meat consumption are different from those of activists and non-profit organizations. By targeting middle of the road consumers, both vegan and humane brands can support widespread efficient and curtailment behaviors and in the process benefit consumers, the brands and society.Originality/valueAnti-consumption and/or reduction of meat and animal by-products are arguably the most impactful ways in which consumers can alter their diets to positively impact individual and societal well-being. Consumers seeking alternatives to traditional meat consumption may either chose more sustainable meat products (efficient behaviors) or reduce/eliminate meat consumption (curtailment behaviors). Existing research suggests that such consumers can be divided into two segments – those driven by personal motives (health and/or taste) and those motivated by prosocial concern (environmental sustainability and/or animal welfare) and brands should match persuasive appeals to consumer motives, i.e. curtailment-focused vegan brands should use environmental or animal justice appeals and efficiency-focused humane meat brands should use taste or health appeals. However, the present research assumes marketers’ perspective and demonstrates that both vegan and humane brands target middle of the road consumers striving to balance multiple personal and prosocial goals, being socially responsible without compromising taste.

Authors: Fernando Yudi , Chidambaram Ramanathan R.M. , Wahyuni-TD Ika Sari 
Published: November 2018

PurposeThe purpose of this paper is to investigate the effects of Big Data analytics, data security and service supply chain innovation capabilities on services supply chain performance.Design/methodology/approachThe paper draws on the relational view of resource-based theory to propose a theoretical model. The data were collected through survey of 145 service firms.FindingsThe results of this study found that the Big Data analytics has a positive and significant relationship with a firm’s ability to manage data security and a positive impact on service supply chain innovation capabilities and service supply chain performance. This study also found that most service firms participating in this study used Big Data analytics to execute existing algorithms faster with larger data sets.Practical implicationsA main recommendation of this study is that service firms empower a chief data officer to establish the data needed and design the governance of data in the company to eliminate any security issues. Data security was a concern if a firm did not have ample data governance and protection as the information was shared among members of service supply chain networks.Originality/valueBig Data analytics are a useful technology tool to forecast market preference based on open source, structured and unstructured data.
Business process model patterns: state-of-the-art, research classification and taxonomy
Authors: Fellmann Michael , Koschmider Agnes , Laue Ralf , Schoknecht Andreas , Vetter Arthur 
Published: November 2018

Purpose
Patterns have proven to be useful for documenting general reusable solutions to a commonly occurring problem. In recent years, several different business process management (BPM)-related patterns have been published. Despite the large number of publications on this subject, there is no work that provides a comprehensive overview and categorization of the published business process model patterns. The purpose of this paper is to close this gap by providing a taxonomy of patterns as well as a classification of 89 research works.

Design/methodology/approach
The authors analyzed 280 research articles following a structured iterative procedure inspired by the method for taxonomy development from Nickerson et al. (2013). Using deductive and inductive reasoning processes embedded in concurrent as well as joint research activities, the authors created a taxonomy of patterns as well as a classification of 89 research works.

Findings
In general, the findings extend the current understanding of BPM patterns. The authors identify pattern categories that are highly populated with research works as well as categories that have received far less attention such as risk and security, the ecological perspective and process architecture. Further, the analysis shows that there is not yet an overarching pattern language for business process model patterns. The insights can be used as starting point for developing such a pattern language.

Originality/value
Up to now, no comprehensive pattern taxonomy and research classification exists. The taxonomy and classification are useful for searching pattern works which is also supported by an accompanying website complementing the work. In regard to future research and publications on patterns, the authors derive recommendations regarding the content and structure of pattern publications.
How organizations learn: models uncovering the black box
Authors: Sharma Shubham , Lenka Usha 
Published: November 2018

Purpose
As contemporary organizations’ focus shifts from knowledge orientation to learning orientation, this paper aims to articulate the need for models that describe the learning process in organizations. Simply assuming that organizations learn without any support of tangible framework or models highlights this need. The paper presents limitations of two prevalent themes of organizational learning, i.e. learning by adapting to environmental disturbances and learning from organizational members.

Design/methodology/approach
Based on the literature review on organizational learning, studies that depict the mechanism of organizational learning were selected. These were grouped into two categories: one that focuses on how organizations learn from its environment and other on how organization learn from its members.

Findings
This paper suggests the need for developing models and frameworks that eloquently describe the learning process in organizations. The literature focuses on organizational learning from individuals and adapting to the environment. Organizations tend to attribute the cause of failure to environmental shocks. Then, instead of the environment being a source of learning, it becomes a cause of failure. If individuals are agents of organization through which the latter learns, how this tacit knowledge becomes institutionalized in organizational memory is unknown.

Originality/value
This paper is a retrospective view on organizational learning. It attempts to question the black box of organizational learning, i.e. how the learning of individuals is transferred to organizational memory, or simply put, how the organizational learning mechanism works. There is a dearth of studies that address this question, and it has been simply assumed that somehow organizations do learn, but how?
Naturo products – sales and distribution management
Authors: Krishnamurthy Rajeshwari 
Published: November 2018

Learning outcomes
The learning outcomes are as follows: understand the factors that go into the assessment of a distributor performance; understand the criteria that may be useful to distributors while choosing distributorship of a fast-moving consumer goods (FMCG) company; understand the various parameters that define a distributor performance; and understand the critical aspects that sales force consider while staying with an organization on the long term.

Case overview/synopsis
This case is about how a FMCG Company in India – Patanjali Products is handling its sales and distribution management strategies. The FMCG segment in India is very competitive and is dominated by big multi- national players such as Unilever and Procter & Gamble as well as other Indian players such as Marico, Dabur, Cavinkare and Himalaya herbal. This industry is characterized by frequent product launches and the trade/ distributors play a key role in providing reach and visibility to the end users. Patanjali Products is a relative new entrant but has rapidly found success in this category. Through a product range that is positioned on “naturalness”, the company has achieved a turnover of US$735m in a span of six years. The case is written from the perspective of Anil Gupta, one of the distributors of the company. He is currently faced with the challenge of evaluating whether he should continue with the distributorship or go back to his old company Himalaya herbal. With this background, the case intends to elaborate on the specific aspects of distributor management and sales management. Some key questions discussed in the case are as follows: What are the aspects that determine the performance of a distributor? What are the parameters that a distributor needs to take into account while selecting a company? How does one calculate the financial return on investment for a FMCG distributor business? What are the elements that contribute to sales force loyalty?

Towards developing an adaptive time stepping for compressible unsteady flows
Authors: Kalkote Nikhil , Assam Ashwani , Eswaran Vinayak 
Published: November 2018

Purpose
The purpose of this paper is to solve unsteady compressible Navier–Stokes equations without the commonly used dual-time loop. The authors would like to use an adaptive time-stepping (ATS)-based local error control instead of CFL-based time-stepping technique. Also, an all-speed flow algorithm is implemented with simple low dissipation AUSM convective scheme, which can be computed without preconditioning which in general destroys the time accuracy.

Design/methodology/approach
In transient flow computations, the time-step is generally determined from the CFL condition. In this paper, the authors demonstrate the usefulness of ATS based on local time-stepping previously used extensively in ordinary differential equations (ODE) integration. This method is implemented in an implicit framework to ensure the numerical domain of dependence always contains the physical domain of dependence.

Findings
In this paper, the authors limit their focus to capture the unsteady physics for three cases: Sod’s shock-tube problem, Stokes’ second problem and a circular cylinder. The use of ATS with local truncation error control enables the solver to use the maximum allowable time-step, for the prescribed tolerance of error. The algorithm is also capable of converging very rapidly to the steady state (if there is any) after the initial transient phase. The authors present here only the first-order time-stepping scheme. An algorithmic comparison is made between the proposed adaptive time-stepping method and the commonly used dual time-stepping approach that indicates the former will be more efficient.

Originality/value
The original method of ATS based on local error control is used extensively in ODE integration, whereas, this method is not so popular in the computational fluid dynamics (CFD) community. In this paper, the authors investigate its use in the unsteady CFD computations. The authors hope that it would provide CFD researchers with an algorithm based on an adaptive time-stepping approach for unsteady calculations.
Effect of thickness and thermal conductivity of metal foams filled in a vertical channel – a numerical study
Authors: Kotresha Banjara , Gnanasekaran N. 
Published: November 2018

PurposeThis paper aims to discuss about the two-dimensional numerical simulations of fluid flow and heat transfer through high thermal conductivity metal foams filled in a vertical channel using the commercial software ANSYS FLUENT.Design/methodology/approachThe Darcy Extended Forchheirmer model is considered for the metal foam region to evaluate the flow characteristics and the local thermal non-equilibrium heat transfer model is considered for the heat transfer analysis; thus the resulting problem becomes conjugate heat transfer.FindingsResults obtained based on the present simulations are validated with the experimental results available in literature and the agreement was found to be good. Parametric studies reveal that the Nusselt number increases in the presence of porous medium with increasing thickness but the effect because of the change in thermal conductivity was found to be insignificant. The results of heat transfer for the metal foams filled in the vertical channel are compared with the clear channel in terms of Colburn j factor and performance factor.Practical implicationsThis paper serves as the current relevance in electronic cooling so as to open up more parametric and optimization studies to develop new class of materials for the enhancement of heat transfer.Originality/valueThe novelty of the present study is to quantify the effect of metal foam thermal conductivity and thickness on the performance of heat transfer and hydrodynamics of the vertical channel for an inlet velocity range of 0.03-3 m/s.
