Authors: Sena José I.V. , Lequesne Cedric , Duchene L , Habraken Anne-Marie , Valente Robertt A.F. , Alves de Sousa Ricardo J 
Published: June 2016

Purpose
– Numerical simulation of the single point incremental forming (SPIF) processes can be very demanding and time consuming due to the constantly changing contact conditions between the tool and the sheet surface, as well as the nonlinear material behaviour combined with non-monotonic strain paths. The purpose of this paper is to propose an adaptive remeshing technique implemented in the in-house implicit finite element code LAGAMINE, to reduce the simulation time. This remeshing technique automatically refines only a portion of the sheet mesh in vicinity of the tool, therefore following the tool motion. As a result, refined meshes are avoided and consequently the total CPU time can be drastically reduced.

Design/methodology/approach
– SPIF is a dieless manufacturing process in which a sheet is deformed by using a tool with a spherical tip. This dieless feature makes the process appropriate for rapid-prototyping and allows for an innovative possibility to reduce overall costs for small batches, since the process can be performed in a rapid and economic way without expensive tooling. As a consequence, research interest related to SPIF process has been growing over the last years.

Findings
– In this work, the proposed automatic refinement technique is applied within a reduced enhanced solid-shell framework to further improve numerical efficiency. In this sense, the use of a hexahedral finite element allows the possibility to use general 3D constitutive laws. Additionally, a direct consideration of thickness variations, double-sided contact conditions and evaluation of all components of the stress field are available with solid-shell and not with shell elements. Additionally, validations by means of benchmarks are carried out, with comparisons against experimental results.

Originality/value
– It is worth noting that no previous work has been carried out using remeshing strategies combined with hexahedral elements in order to improve the computational efficiency resorting to an implicit scheme, which makes this work innovative. Finally, it has been shown that it is possible to perform accurate and efficient finite element simulations of SPIF process, resorting to implicit analysis and continuum elements. This is definitively a step-forward on the state-of-art in this field.
Crashworthiness optimization of circular tubes with functionally-graded thickness
Authors: Baykasoglu Adil , Baykasoglu Cengiz 
Published: June 2016

Purpose
– The purpose of this paper is to develop a new multi-objective optimization procedure for crashworthiness optimization of thin-walled structures especially circular tubes with functionally graded thickness.

Design/methodology/approach
– The proposed optimization approach is based on finite element analyses for construction of sample design space and verification; gene-expression programming (GEP) for generating algebraic equations (meta-models) to compute objective functions values (peak crash force and specific energy absorption) for design parameters; multi-objective genetic algorithms for generating design parameters alternatives and determining optimal combination of them. The authors have also utilized linear and non-linear least square regression meta-models as a benchmark for GEP.

Findings
– It is shown that the proposed approach is able to generate Pareto optimal designs which are in a very good agreement with the actual results.

Originality/value
– The paper presents the application of a genetic programming-based method, namely, GEP first time in the literature. The proposed approach can be used to all kinds of related crashworthiness problems.

First Telecom – India 2.0 strategy
Authors: Singhania Monica , Gupta Puneet 
Published: June 2016

Subject area
This case looks at a recent shift in the way organizations look to leverage the benefits from India as a cost-effective destination to provide services. What started, around 15 years back, as an activity to outsource all non-core activities to Indian companies to take the advantage of cost-effective resources, has now given way to a new model where the focus is on two key aspects, namely, “insourcing of work” and “transfer of core activities to India”. This is because of the realization that outsourcing may be a short-term solution for non-core activities; however, to build a sustainable capability that is both cost-effective and value-oriented, insourcing is key. Also, it is not just non-core activities that can be supported remotely; many core activities that have been managed by on-shore teams are increasingly being shifted to India to leverage the depth of skills available in the country. First Telecom has undertaken pioneering work in this domain by moving some of the critical functions to India and has created Centers of Excellence (CoEs) providing niche services to rest of the world.

Study level/applicability
Target audience includes corporate executives, students of MBA/postgraduate program in management in strategic management and/or workshops for understanding the concept of insourcing, cost transformation, business environment analysis and growth strategies for future.

Case overview
First Telecom has adopted what could be termed as “India 2.0” as the strategy to transform their operations worldwide to utilize the full potential of “India” as a service sector-outsourcing destination. The focus is not only on cost-avoidance but also on standardization of processes and mobilization of resources in a CoE setting to maximize the benefits. This case attempts to understand the way to go about it and the expected returns in a quantifiable manner.

Expected learning outcomes
To develop an understanding of business environment in the context of large multinational organizations that are constantly evolving to improve their operational excellence. Also, to develop an understanding of the outsourcing market and how companies are looking to move their core services to cost-effective locations to achieve the next phase of cost transformation after the outsourcing (non-core services) wave.

Strategic management in cartelized environment: case of Hisham Packaging, Dubai
Authors: Laeequddin Mohammed , Abdul Waheed K. 
Published: June 2016

Subject area
Business-to-business (B2B) marketing, microeconomics and strategic management.

Study level/applicability
Target audience can be MBA students who are taking B2B marketing, microeconomics and strategic management courses.

Case overview
On 1 January 2015, Hamza joined Hisham Packaging, Dubai, United Arab Emirates (UAE) as the CEO. Hisham Packaging specialises in production of corrugated boxes of various sizes, both in plain and printed forms. Most of Hamza’s experiences have been in the automobile industry, where his focus was on Lean operations rather than marketing. After joining Hisham Packaging, he learnt that in service industry like printing and packaging, the business focus is more customer-oriented than process-orientated. In the packaging industry, each customer’s requirement is unique and customised with variety and small volumes. What was shocking to him was that there is an informal cartel arrangement among major corrugated box suppliers in the country and without the consent of the cartel members, he cannot take any major decision like expanding the business or accepting or dropping a customer. Hamza discussed the scenario with his sales manager Ahmad to see what strategy to adopt for the growth of the company. He was trying to figure out what next? Like any other newly joined CEO, Hamza also had plans to increase the market share and make the operations Lean. He quickly found that it would be difficult for him to make any major impact on the existing business due to the constraints and he needed a different strategic move to grow the company.

Expected learning outcomes
The outcomes include understanding of market dynamics, cartelization of companies based on market structure and strategy building. Students learn that an organization’s performance is just not dependent on how the managers plan, organize and control but it also depends on the competitors and customer’s strategies. Students learn how to apply strengths, weaknesses, opportunities, and threats (SWOT) analysis, Porter’s Five Forces analysis and PESTEL analysis in developing business strategy.

Published: June 2016

Subject area
Finance, General Business Management.

Study level/applicability
Postgraduate/MBA Second Year.

Case overview
The university-owned Universal Computing Limited (UCL) was contemplating on the future of its internet services business. Internally, the internet services department had put up a proposal on how to revamp the business. Concurrently, UCL received a joint venture proposition from a foreign telecommunication entity with which it had some business relation. The proposal was for UCL to cede its internet services department and the associated licence to the venture while the partner will finance the venture. Professor Ben Msomi, the UCL’s Managing Director knew that he had to make one of the two proposals a good sell to the board of directors’ meeting in two-weeks’ time probably before suggesting UCL to exit the internet services business.

Expected learning outcomes
Overall, the case aims at gaining an understanding of the sources of value of business and valuation of business. Specifically students are expected to learn how to: evaluate of the effect of various courses of action on the value of a business; apply different valuation methods – balance sheet, discounted cash-flows and market multiples in different context; establish appropriate rate for capitalization in business valuation; and handle assumptions and risks in business valuation,

Investigation of thermochemical boriding effect on wear behavior of a GGG 50 quality as-cast ductile iron
Authors: Mindivan Harun 
Published: June 2016

Purpose
This study aims to investigate the microstructure and the abrasive wear features of the untreated and pack borided GGG 50 quality ductile iron under various working temperatures.

Design/methodology/approach
GGG 50 quality as-cast ductile iron samples were pack borided in Ekabor II powder at 900°C for 3 h, followed by furnace cooling. Structural characterization was made by optical microscopy. Mechanical characterization was made by hardness and pin-on-disc wear test. Pin-on-disc test was conducted on a 240-mesh Al2O3 abrasive paper at various temperatures in between 25 and 450°C.

Findings
Room temperature abrasive wear resistance of the borided ductile iron increased with an increase in its surface hardness. High-temperature abrasive wear resistances of the borided ductile iron linearly decreased with an increase in test temperature. However, the untreated ductile iron exhibited relatively high resistance to abrasion at a temperature of 150°C.

Originality/value
This study can be a practical reference and offers insight into the effects of boriding process on the increase of room temperature wear resistance. However, above 150°C, the untreated ductile iron exhibited similar abrasive wear performance as compared to the borided ductile iron.
Solving the Moro problem: legalizing the Bangsamoro peace process
Authors: Carolan Gene 
Published: June 2016

Purpose– The purpose of this paper is to highlight the structural features that are proving central to the stability of the 2014 Comprehensive Agreement on the Bangsamoro between the Government of the Philippines and the Moro Islamic Liberation Front, and those features that were detrimental to its predecessors.Design/methodology/approach– This paper adopts a legalization framework derived from the model presented by Abbottet al.The simplicity of Abbottet al.’s theory allows for variation in the agreements’ text to be easily measured and compared. The inherent advantages of this model offset the difficulties in characterizing peace agreements under traditional legal methodologies, and reiterate the importance of legalized agreements in a conflict resolution context.Findings– This paper finds that a more highly legalized approach to peace-making has resulted in greater agreement stability in the Philippines. More precise in detail and inclusive in scope, the legal nature of the 2014 Comprehensive Agreement has made it more responsive to the root causes of the conflict, and resilient to incidents that threatened to derail the peace process.Practical implications– This case study bears valuable lessons for conflict zones the world over, particularly the troubled negotiations on Syria, and the crisis in Ukraine. The study: lends tentative support to Gopalan’s claim that agreements that exemplify hard legalization are much more sustainable in the long run; stresses the advantages of inclusivity in agreement sustainability and stability; reiterates the importance of addressing the key issues relevant to the conflict if the process is to be sustainable, and; notes the limitations of the legalization framework, but presents the Philippine example as a blueprint for addressing various aspects of the Syrian and Ukrainian conflicts.Originality/value– This is the first peer-reviewed analysis to explore the 2014 Comprehensive Agreement as a highly legalized conflict resolution instrument, and an adaptable template for peace agreement design generally.
Individual differences impact support for vigilante justice
Authors: McDermott Christine M , Miller Monica K 
Published: June 2016

Purpose– The purpose of this paper is to explore the relationships between moral disengagement, individual differences (i.e. need for cognition (NFC), faith in intuition, legal authoritarianism) and responses to vigilantism.Design/methodology/approach– US university students were surveyed.Findings– NFC reduced support for vigilante justice while legal authoritarianism increased support for vigilante justice. Both relationships are mediated by moral disengagement, which also increases support for vigilante justice.Research limitations/implications– The present study provides a starting point for further research on individual differences and responses to vigilantism.Practical implications– Results expand on the understanding of the function of individual differences in a morally charged decision-making task. Content has implications for academics and legal practitioners.Originality/value– Vigilante justice is embedded within American culture. However, vigilantism is currently illegal, and recent instances of what might be considered vigilante justice (e.g. George Zimmerman, David Barajas) have highlighted the controversy surrounding such extralegal violence. Little research has focussed on the moral quandary posed by vigilantism.
Placement experience and learning motivations in higher education
Authors: Gavin James P , Coleman Ian 
Published: June 2016

Purpose
– Placement-based learning is claimed to benefit educational outcomes in undergraduate programmes, with students gaining employability skills and the application of skill-sets in “real world” situations. Most courses incorporate experiential learning; however, work placements remain exclusive to the aims of the academic programme. The purpose of this paper is to explore the changing learning motivations between students enroled on: a practical-based programme, involving work placement (BA adventure education (Ad Ed)); and a study-based programme (BSc sport and exercise science (SES)). In addition, motivation was examined between courses at each year.

Design/methodology/approach
– A 44 item Motivated Strategies for Learning Questionnaire was completed by first and final year undergraduates studying BA Ad Ed and BSc SES courses in the academic year 2011/2012. Questionnaires were triangulated with focus groups, lecturer observations and statistical analyses.

Findings
– Learning motivation was influenced by: knowledge of academic grades; link between theoretical content and work experience; opportunity for reflection; and multidisciplinary nature of degree programmes. Furthermore, the majority of final year Ad Ed students showed understanding of the job market, degree transferability and career availability upon graduation.

Originality/value
– Where placement experience prepares British undergraduate learners for employment and provides insight into career demand, placements may also demotivate, particularly where careers do not necessitate degree qualification.
Fair value and banking contagion
Authors: Gharbi Leila , Khamoussi Halioui 
Published: June 2016

Purpose
This paper aims to explore empirically the impact of fair value accounting on banking contagion in a comparative context between Islamic banks and conventional banks.

Design/methodology/approach
The analysis of the impact of fair value changes on banking contagion is carried out through a panel data model. This study covers 20 Islamic banks and 40 conventional banks operating in the Gulf Cooperation Council (GCC) countries during nine years from 2003 to 2011.

Findings
Empirical evidence shows that there is a significant change in dynamic volatility in GCC banking sector because of financial crisis 2008. However, results fail to confirm the hypothesis that fair value accounting is significantly associated with an increase of banking contagion for both Islamic and conventional banks operating in GCC countries.

Originality/value
The outcome of this study provides some insights for academicians, accountants as well as regulators in terms of enhancing the effectiveness of accounting practices.
Measuring environmental performance in hospitals: a framework and process
Authors: Pasqualini Blass Andreia , Gouvea da Costa Sergio E. , Pinheiro de Lima Edson , Borges Lilian Adriana 
Published: June 2016

PurposeThis paper aims to propose a new framework to define relevant and meaningful indicators for monitoring and assessing environmental performance to improve health-care systems and operations.Design/methodology/approachA comprehensive literature review followed by field studies conducted with ten hospitals in the southern region of Brazil underlined the scarcity of consistent frameworks applied in practice to measure, monitor and improve environmental performance. A new framework was developed and proposed to address this issue. The proposed framework is operationalized through a “process approach” and evaluated in terms of feasibility (Can the process be followed?), usability (Is the approach easily followed?) and utility (Are the results useful for managers?).FindingsThe paper proposes a framework and a process to evaluate the environmental performance in hospitals.Practical implicationsThe proposed framework represents meaningful guidance to managers for strategy formalization, goal setting and environmental performance assessment and monitoring.Originality/valueThe paper proposes a systematic framework for measuring environmental performance in hospitals drawn from the literature review, current legislation and best practices reported in literature.
The role of absorptive capacity in Chinese firms
Authors: Petti Claudio , Zhang Shujun 
Published: June 2016

Purpose
This study aims to advance and test a multi-dimensional operationalization of absorptive capacity (ACAP) to ascertain its mediating role in the transformation of R&D expenses in actual performance.

Design/methodology/approach
This study departs from the conceptualization of ACAP as a reflective higher-order R&D-based construct, by specifying ACAP into its components and using an operationalization that encompasses both R&D and non-R&D measures to perform mediation analysis on a sample of 1,096 Chinese mainland firms.

Findings
This study's findings report evidence of positive but different roles of the components of ACAP, with specific reference to the positive but partial mediating role of realized ACAP between both R&D expenses and potential ACAP on a firm’s performance. Relevant research and practical implications for both management and policymaking are discussed.

Originality/value
The approach to ACAP conceptualization and measurement taken in this study provides empirical support to an often assumed and, incidentally, under-explored relationship. Moreover, it contributes with a multi-dimensional, non-exclusively R&D-based and process-oriented perspective to the analysis of the role played by ACAP in Chinese firms’ R&D effectiveness.
