Does gender diversity on boards influence stock market liquidity? Empirical evidence from the French market
Authors: Loukil Nadia , Yousfi Ouidad , Yerbanga Raissa 
Published: June 2019

Purpose
The purpose of this paper is to examine the gender diversity on boards and its effect on stock market liquidity in French boardrooms.

Design/methodology/approach
Using a sample of French firms between 2002 and 2012 listed on the Paris Stock Exchange (SBF120), the study uses ordinary least squares and three-stage least squares (3SLS) regressions to address endogeneity concerns on the board gender diversity.

Findings
The results show that stock market liquidity is positively and significantly associated with the presence of women directors. The authors find that investors’ decisions vary according to their positions in the board: women independent members decrease illiquidity costs, while the presence of female inside directors increases daily trading volume. In addition, the presence of female inside directors increases the firm’s ability to implement better strategies that cope with economic, social and environmental constraints which leads investors to positively react. Surprisingly, the presence of female independent directors reduces company involvement in sustainable development projects.

Practical implications
The empirical findings contribute to the current debate on the benefits of gender diversity on corporate boards and the effectiveness of gender-quota laws. It shows that appointing insider female’ directors incite investors to trade more stocks while appointing independents ones reduces their trading costs.

Social implications
This paper shows that the benefits of female directors appointing depend on their independence of management team.

Originality/value
This study addresses the endogeneity between stock market liquidity, corporate governance and gender diversity. It is the first study to distinguish between the effects of women inside and independent directors on investors’ trading decisions.

Numerical optimization of obstructed high temperature heat exchanger for recovery from the flue gases by considering ash fouling characteristics
Authors: Abbasian Arani Ali Akbar , Arefmanesh Ali , Ehteram Hamidreza 
Published: June 2019

Purpose
The purpose of this paper is to recommend a validated numerical model for simulation the flue gases heat recovery recuperators. Due to fulfill of this demand, the influences of ash fouling characteristics during the transient/steady-state simulation and optimization of a 3D complex heat exchanger equipped with inner plain fins and side plate fins are studied.

Design/methodology/approach
For the particle dispersion modeling, the discrete phase model is applied and the flow field has been solved using SIMPLE algorithm.

Findings
According to obtained results, for the recuperator equipped with combine inner plain and side plate fins, determination of ash fouling characteristics is really important, effective and determinative. It is clear that by underestimating the ash fouling characteristics, the achieved results are wrong and different with reality.

Originality/value
Finally, the configuration with inner plain fins with characteristics of: di =5 mm, do = 6 mm, dg = 2 mm, dk = 3 mm and NIPFT = 9 and side plate fins with characteristics of: TF = 3 mm, PF = 19 mm, NSPF = 17·2 = 34, WF = 10 mm, HF = 25 mm, LF = 24 mm and ß = 0° is introduced as the optimum model with the best performance among all studied configurations.
Flow–pressure drop characteristics of perforated plates
Authors: Tanner Phillip , Gorman John , Sparrow Eph 
Published: June 2019

Purpose
The purpose of this study is to quantify the relationship between the fluid flow and pressure drop for perforated plates. The homogenization of non-uniform fluid flows is often accomplished by passing the fluid through perforated plates. The underlying principle for the accomplishment of flow homogenization is a tradeoff of pressure drop for flow uniformity.

Design/methodology/approach
The investigation, implemented by numerical simulation, is based on turbulent flow in pipes and across perforated plates. The approach is as follows: (a) to devise a model to determine pressure drop’s fluid flow information from a single-aperture, (b) to obtain this information for apertures of different shapes, (c) to determine this type of information for perforated plates situated in a circular pipe, (d) to compare the entire perforated-plate pressure drop with that for a single-aperture modular and (e) to analyze two identical perforated plates in series.

Findings
The pressure drop results for the single-aperture modular model agreed very well with those for a whole perforated plate in a round pipe, therefore negating the need to simulate the more complex situation. In addition to the parametric study with aperture shape and Reynolds number, porosities (20-60 per cent) and plate thicknesses were also varied. The results obtained here compared favorably with experimental data.

Originality/value
This work demonstrates an efficient method for analyzing and obtaining useful pressure drop information for perforated plates. For the first time, the porous media approach for modeling perforated plates is compared directly to complete, full-scale perforated plate applications and identical plates in series.
An experimental evaluation of bow-tie analysis for security
Authors: Meland Per Håkon , Bernsmed Karin , Frøystad Christian , Li Jingyue , Sindre Guttorm 
Published: June 2019

Purpose
Within critical-infrastructure industries, bow-tie analysis is an established way of eliciting requirements for safety and reliability concerns. Because of the ever-increasing digitalisation and coupling between the cyber and physical world, security has become an additional concern in these industries. The purpose of this paper is to evaluate how well bow-tie analysis performs in the context of security, and the study’s hypothesis is that the bow-tie notation has a suitable expressiveness for security and safety.

Design/methodology/approach
This study uses a formal, controlled quasi-experiment on two sample populations – security experts and security graduate students – working on the same case. As a basis for comparison, the authors used a similar experiment with misuse case analysis, a well-known technique for graphical security modelling.

Findings
The results show that the collective group of graduate students, inexperienced in security modelling, perform similarly as security experts in a well-defined scope and familiar target system/situation. The students showed great creativity, covering most of the same threats and consequences as the experts identified and discovering additional ones. One notable difference was that these naïve professionals tend to focus on preventive barriers, leading to requirements for risk mitigation or avoidance, while experienced professionals seem to balance this more with reactive barriers and requirements for incident management.

Originality/value
Our results are useful in areas where we need to evaluate safety and security concerns together, especially for domains that have experience in health, safety and environmental hazards, but now need to expand this with cybersecurity as well.
Dynamics of banking sector integration in South Asia: an empirical study
Authors: Pandey Piyush , Sehgal Sanjay , Ahmad Wasim 
Published: June 2019

Purpose
Banks in the South Asian region are the fulcrum of economic growth and development as they provide means to development credit and working capital, trade and infrastructure finance and are seen as custodians of the trust in the financial system. This paper aims to study the nature of banking sector linkages for the region.

Design/methodology/approach
The dependence structure between deposits and lending rates individually for the banks of the South Asian countries are studied using time invariant and time varying family of copula functions. The degree of connectedness is further studied by Diebold and Yilmaz methodology.

Findings
Results indicate poor levels of banking integration in the region as the dependence parameter for both deposits and lending rates was around 0 for the sample countries, thereby confirming poor banking sector integration in the region.

Practical implications
Policymakers of the region are interested in the co-movements of the interest rates to understand the cross-sector risk management and any systemic risk pressures for the regional economies. Corporates in these countries are scouting out for competitive borrowing rates to lower their cost of capital.

Social implications
Rationale for examining the banking sector linkages is that the South Asian countries are at different stages of economic growth and development and this region in particular is the fastest growing region in the world and has largely increased its trade integration with the world albeit having lowest levels of intra-regional trade integration.

Originality/value
This is a first of a kind of studies to examine the banking sector linkages in South Asia.

Authors: Lei Sut Ieng , Wang Dan , Law Rob 
Published: June 2019

Purpose
This study aims to investigate how hoteliers leverage mobile technologies to shape services that allow customers to create their own unique and personalized experiences.

Design/methodology/approach
Guided by service-dominant logic and sociomateriality, this study analyzes hoteliers’ reasoning behind the design of mobile-based services through qualitative research. Data were collected from interviews with hotel managers representing best-practice companies in the industry.

Findings
The findings provide a rich description of mobile-based value co-creation in the hotel context. They delineate hoteliers’ understanding of mobile technologies as a means to co-create value, their strategic considerations and the forms in which value is expected to be co-created.

Research limitations/implications
This study unearths the new roles of hoteliers, unique forms of value co-creation and their underlying structures in the specific context of mobile-based value co-creation. Practical implications based on industry best practices are provided for hospitality companies seeking to innovate by co-creating value with customers using mobile technologies.

Originality/value
This research paper contributes to the hospitality literature on IT-enabled service innovation and value co-creation by comprehensively explaining the underlying structure and design of co-created experiences facilitated by mobile-based services.
The project manager core competencies to project success
Authors: Alvarenga Jeferson Carvalho , Branco Robson Rosa , Guedes André Luis Azevedo , Soares Carlos Alberto Pereira , Silva Wainer da Silveira e 
Published: June 2019

Purpose
The past few decades have produced a number of investigations into the correlation between project managers’ competencies and project success. As a result, competencies lists have become extensive “shopping lists.” The purpose of this paper is to define the most important competencies to project success and investigate their correlations.

Design/methodology/approach
The authors surveyed project managers on the importance of 28 project manager competencies to project success. Data were analyzed using univariate and multivariate procedures.

Findings
Data show that communication, commitment and leadership appear as the three most relevant aspects. Multivariate analysis identified seven groups of competencies: leadership, self-management, interpersonal, communication, technical, productivity and managerial.

Practical implications
The results confirm a growing trend toward soft skills and reinforce the need for an update on project management education to fill the gap between theory and practice.

Originality/value
Project manager competencies lists have become too extensive, and the field is in constant change; therefore, this study updates the discussion and downsizes the number of competencies to fewer, more relevant items.
Dynamics of Muslim consumers’ behavior toward Halal products
Authors: Al-Kwifi Osama Sam , Abu Farha Allam , Ahmed Zafar U. 
Published: June 2019

Purpose
Since Islamic markets are growing substantially, there is an urgent need to gain a better understanding of how Muslim consumers perceive products from a religious perspective. The purpose of this paper is to investigate the brain responses of Muslim consumers to Halal and non-Halal products using a functional magnetic resonance imaging (fMRI) technology.

Design/methodology/approach
The research model is a simplified version of the theory of planned behavior. The initial experiment began by asking participants to divide a set of images into two groups: Halal and non-Halal products. The fMRI experiment uses a blocked design approach to capture brain activities resulting from presenting the two groups of images to participants, and to record the strength of their attitudes toward purchasing the products.

Findings
Across all participants, the level of brain activation in the ventromedial prefrontal cortex increased significantly when Halal images were presented to them. The same results emerged when the Halal images showed raw and cooked meat. The variations in the results may be due to the high emotional sensitivity of Muslim consumers to using religious products.

Research limitations/implications
This study uses a unique approach to monitor brain activity to confirm that consumers from specific market segments respond differently to market products based on their internal beliefs. Findings from this study provide evidence that marketing managers targeting Muslim markets should consider the sensitivity of presenting products in ways that reflect religious principles, in order to gain higher acceptance in this market segment.

Originality/value
Although the literature reports considerable research on Muslim consumers’ behavior, most of the previous studies utilize conventional data collection approaches to target broad segments of consumers by using traditional products. This paper is the first to track the reactions of the Muslim consumer segment to specific types of market products.
The role of structural assurance on previous satisfaction, trust and continuance intention
Authors: McCole Patrick , Ramsey Elaine , Kincaid Andrew , Fang Yulin , LI Huifang 
Published: June 2019

Purpose
Varied accounts exist regarding the role of trust and satisfaction in online continuance intention and contexts within which this occurs. The purpose of this paper is to consider the moderating effect of structural assurance (SA) on satisfaction and trust and trust and continuance intention in a pure e-service context (online betting).

Design/methodology/approach
UK online bettors were surveyed with an instrument developed using validated variables and measurements, including continuance intention, satisfaction, trust (in vendor) and SA. Structural equation modeling with partial least squares was used to evaluate the measurement and structural model simultaneously.

Findings
SA positively moderates the trust–continuance intention relationship but not the satisfaction–trust relationship. SA is positively associated with trust.

Research limitations/implications
The study contributes to research focused on exploring the moderating effects of trust and satisfaction on continuance intention where institution-based mechanisms are perceived to be effective and framed to assure success.

Practical implications
An over-reliance on context-specific mechanisms is inadequate; strategic approaches to trust must consider contextual and institutional mechanisms interdependently.

Originality/value
The paper addresses the need for research relating to the institutional context within which trust mechanisms operate. This research provides a novel contribution through an exploration of the moderating effects of SA on: trust and continuance intention; and satisfaction and trust (the authors also measure the direct effect of SA on trust). This paper is one of the first studies to examine these important concepts in this context. The online betting case allows for the exploration of risk where vendor-specific and contextual risk are both high.

Authors: Jowah Larry Enoch , Beretu Tendency 
Published: June 2019

Purpose
The purpose of this paper is to provide an insight into the need to provide an industry-relevant curricula to higher learning institutions, which addresses the needs of the industries so that unemployment is addressed.

Design/methodology/approach
The researcher sought to look for a cause and consequence relationship, which resulted in the usage of a mixed-methods approach whereby both qualitative and quantitative research methods were used. Correspondingly, the study was conducted in two phases, literature analysis and experimental study, including field work.

Findings
The paper provides experiential visions about how institutions of higher learning can provide industry-relevant education. It proposes that for graduates to be employable, there should be synergy between what industries want and what the institutions of higher learning are providing, hence the need to redesign the curricula.

Research limitations/implications
The research focused exclusively on Cape Peninsula University of Technology HR graduates from 2014 to 2017 instead of considering all graduates of HR in the workplaces in Cape Metropolis.

Practical implications
Tertiary institutions as the custodians of knowledge will have to go out to the customers (recipients of their products) and inquire for relevant operational requirements.

Social implications
HR graduates will be properly empowered through proper industry-relevant curriculum which enables them to be employable or to create employment instead of waiting to be employed.

Originality/value
This paper fulfills a recognized need to study how the curriculum offered by universities contributes to the employability of human resources management graduates.
Optimal capacity utilisation of transmission lines network in power flow operations: a survey
Authors: Okojie Daniel Esene , Jimoh Adisa Abdul-Ganiyu , Hamam Yskandar , Yusuff Adebayo Ademola 
Published: June 2019

Purpose
This paper aims to survey the need for full capacity utilisation of transmission lines in power systems network operations. It proposes a review of the N-1 security criterion that does not ensure reliable dispatch of optimum power flow during outage contingency. The survey aims to enlarge the network capacity utilisation to rely on the entire transmission lines network operation.

Design/methodology/approach
The paper suggests transmission line switching (TLS) approach as a viable corrective mechanism for power dispatch. The TLS process is incorporated into a constraint programming language extension optimisation solver that selects the switchable line candidates as integer variables in the mixed integer programming problem.

Findings
The paper provides a practical awareness of reserve capacity in the lines that provide network security in outage contingency. At optimum power flow dispatch, the TLS is extended to optimal transmission line switching (OTLS) that indicates optimal capacity utilisation (OCU) of the available reserve capacity (ARC) in the network lines.

Practical implications
Computational efficiency influenced the extension of the OTLS to optimal transmission switching of power flow (OTSPF). The application of OTSPF helps reduce the use of flexible AC transmission systems (FACTS) and construction of new transmission lines..

Originality/value
The paper surveys TLS efforts in network capacity utilisation. The suggested ARC fulfils the need for an index with which the dispatchable lines may be identified for the optimal capacity utilisation of transmission lines network.
