Authors: Wang Mengdi , Li Dong 
Published: October 2018

PurposeIn accordance with Bagozzi’s self-regulation theory, the aim of this paper is to explore the enablers and inhibitors of continuance intention from the perspective of bullet curtain, a new form of commentary on online video websites.Design/methodology/approachA total of 350 questionnaires were collected for the final analysis (covering 101 questionnaires for the pilot test) from China’s bullet curtain website. To analyze the model, the authors adopted SmartPLS 3.2, a structural equation modeling software.FindingsAs the results suggest, there is a positive correlation between satisfaction and continuance intention and a negative association between social network fatigue and continuance intention. In addition, synchronicity between the comments and video content, a dimension of synchronicity proposed in this study, improves the satisfaction. Furthermore, information overload significantly intensify social network fatigue.Practical implicationsThe results help bullet curtain providers offer better interactive environment and improve websites’ functions to stimulate users.Originality/valueBy combining positive effect and negative effect of commentary, this study investigates Bagozzi’s theory in a context of bullet curtain. Besides, combinations of these factors help to gain insights in how the bullet curtain works in online video websites. These offer useful guidelines for managers to optimize a better system.
Numerical study on the perforation of steel plates by multiple projectiles
Authors: Xiao Yihua , Dong Huanghuang , Zhan Haifei , Zhu Aihua 
Published: October 2018

Purpose
Metal plates are usually used as protective shields of engineering structures, which probably undergo multiple projectile impacts resulting from gunshot and blast. Though a large number of studies have been conducted on the performance of metal plates under a single projectile impact, few studies have explored their performance under multiple projectile impacts. This paper aims to explore the performance of Weldox 460 E steel plates against multiple projectile impacts through numerical simulation.

Design/methodology/approach
A three-dimensional coupled finite element (FE) and smoothed particle hydrodynamics (SPH) model was developed to simulate the perforation of a 12-mm-thick Weldox 460 E steel plate by an ogival projectile. The model was verified by existing experimental data. Then, it was extended to investigate the same target plate subjected to impacts with multiple projectiles. Simultaneous impacts with different number of projectiles, as well as sequential impacts with two projectiles, were considered.

Findings
Effects of spacing between projectiles on residual velocity of projectile, ballistic limit and failure mode of target were revealed for simultaneous impacts. Effects of spacing and axial distance between projectiles on residual velocity of projectile were explored for sequential impacts.

Originality/value
This work developed an advanced FE–SPH model to simulate perforation of steel plates by multiple projectiles, and revealed the effects of multiple impacts on ballistic performance of steel plates. It provides guidance for the design of protective structures/shields in various engineering applications.

Authors: Talbi Dorra , Bougatef Khemaies 
Published: October 2018

PurposeThe purpose of this paper is to conduct a comparative analysis of internal and external determinants of bank’s performance in Middle East and North Africa (MENA) countries.Design/methodology/approachThe authors use a static unbalanced annual panel data of banks operating in eight countries pertaining to the MENA region (Tunisia, Bahrain, Egypt, Jordan, Qatar, Lebanon, Kingdom of Saudi Arabia and United Arab Emirates) over the period from 1999 to 2014.FindingsThe findings reveal that the determinants of intermediation margins in the MENA region differ across countries. Overall, banks interest margins are explained by both bank-specific variables and macroeconomic factors except for Saudi Arabia in which interest margins exclusively depend on bank-specific factors.Originality/valueThese findings contribute to the clarification and critical analysis of the current state of bank’s performance in some countries located in MENA region, which would have several crucial policy implications.
Does trust in organization mediate the influence of servant leadership on satisfaction outcomes among flight attendants?
Authors: Ilkhanizadeh Shiva , Karatepe Osman M. 
Published: October 2018

PurposeDrawing from servant leadership (SL) and social exchange theories, our study investigates trust in organization (TIO) as a mediator of the impact of SL on job, career and life satisfaction.Design/methodology/approachA time-lagged survey design was used to gather data from flight attendants in Turkey. Structural equation modeling was used as the main analytic tool to assess these relationships.FindingsThe relationships proposed in the authors’ study receive full support from the empirical data. Specifically, TIO is one of the immediate outcomes of SL that engenders job, career and life satisfaction at elevated levels. The results highlight the impacts of job and career satisfaction in the intermediate linkage between SL and life satisfaction.Practical implicationsManagement should train managerial employees to enhance the understanding of SL, which boosts flight attendants’ TIO. Management should invest in human resources through training and empowerment. This makes flight attendants perceive that management does not violate psychological contract. Such employees develop TIO that in turn engenders higher job, career and life satisfaction. It is also important to reward servant leaders when they succeed in making flight attendants develop TIO and motivating them to have higher job performance.Originality/valueLittle is known about the consequences of SL in the extant service research. More importantly, there are still calls for research about the variables (e.g. TIO) mediating the relationship between SL and employee satisfaction outcomes.
Earnings management in corporate enterprises in India
Authors: Goel Sandeep 
Published: October 2018

PurposeThe earnings management (EM) research on the impact of firm’s multi-nationality and reputation on the earnings’ quality is limited, particularly in the context of emerging economies like India. In India, the corporate ownership model is “Promoter-dominated shareholder model” wherein companies have global operations. The purpose of this paper is to analyze the EM practices of corporate enterprises in India about multi-nationality, reputation and related determinants.Design/methodology/approachThe present study employs DeAngelo model for calculating discretionary accruals for detecting EM. Multi-nationality, reputation and related determinants are measured as accounting indices. The statistical tools applied for testing the accuracy of results include correlation and regression analysis,t-test and descriptive statistics, like arithmetic mean, median and standard deviation.FindingsThe results show that multi-nationality is the driving force for EM and significantly affects the accounting choices of management in the sample units. The firm’s reputation and other related determinants, except size, vary with accruals. The earnings behavior of the corporate is influenced by other factors, like growth and leverage as well.Research limitations/implicationsA total of 12 units out of top 25 units, taken for the study, met the sampling requirements. So, the present study is confined to 12 profit-making private listed companies in India. These companies constitute a significant size of BSE’s market capitalization for completeness of data; still the size and diversity of units can be extended for further study. The period in the study is of five years (2003–2004 to 2007–2008) to find the effects of global recession on EM practices in India. Researchers may like to select a different time-period based on their objective.Practical implicationsThe study draws new dimensions about the quality of financial reporting in case of global firms and with high-perceived reputation. The findings are of significance to standard setters and regulators, particularly for emerging economies, like India where companies have international operations. They are equally important for other companies that are based in economies with relatively mature corporate governance mechanisms because of common regulatory focal points.Social implicationsIt brings out the importance of financial reporting process of global corporations for shareholders’ value creation. It is likely to enrich the knowledge and understanding of the EM phenomenon in developing economies like India.Originality/valueIt is an original paper, which highlights the EM motivation about multi-nationality, reputation and related variables in Indian corporate.
Does heterogeneity matter to the direct effect of FDI on firm performance?
Authors: Song Young Chul , Lie Han Young 
Published: October 2018

PurposeThe purpose of this paper is to estimate the direct effects of foreign direct investment (FDI) on domestic target firms’ profitability gains, in India, post-acquisition. In particular, it focuses on identifying the importance of firms’ heterogeneities on the effects, taking into account the source of FDI, the intensity of firm interaction, and the target firms’ technology-absorptive capacity. Most importantly, the paper investigates whether the estimates depend on a combined rather than single impact of these heterogeneities.Design/methodology/approachTo control for the possibility of selection bias and endogeneity, this empirical analysis uses a methodology that combines propensity score matching and difference-in-differences (PSM–DID) in adopting a comprehensive data set of both foreign- and Indian-acquired firms that were purchased through mergers and acquisitions in India between 1991 and 2013.FindingsThe analysis reveals four major findings. First, overall, the post-foreign acquisition target firms’ performance gains were positive and varied by the heterogeneous technology transfer capacity of the foreign investor. Second, it is possible that target firms located in industrial clusters with more foreign agglomeration experienced larger profitability gains through more dynamic firm interactions in terms of spillovers. Third, Indian targets with higher technology-absorptive capacity benefitted in higher profitability gains from acquiring and assimilating the superior technology that is transferred from foreign investors. Finally, an optimal combination of Indian target firms with higher technology-absorptive capacity and foreign investors with higher technology transfer capacity maximizes profitability gains, post-acquisition. This synergy effect is particularly prominent in clusters where more foreign firms agglomerate.Originality/valueThis study captures the true direct effect of FDI by adjusting the combined causal effects of various inherent heterogeneities in the target firms’ performance, thus correcting any possible bias, which few previous studies have addressed.
The flank wear prediction in micro-milling Inconel 718
Authors: Lu Xiaohong , Wang FuRui , Jia Zhenyuan , Liang Steven Y. 
Published: October 2018

Purpose
Cutting tool wear is known to affect tool life, surface quality, cutting forces and production time. Micro-milling of difficult-to-cut materials like Inconel 718 leads to significant flank wear on the cutting tool. To ensure the respect of final part specifications and to study cutting forces and tool catastrophic failure, flank wear (VB) has to be controlled. This paper aims to achieve flank wear prediction during micro-milling process, which fills the void of the commercial finite element software.

Design/methodology/approach
Based on tool geometry structure and DEFORM finite element simulation, flank wear of the micro tool during micro-milling process is obtained. Finally, experiments of micro-milling Inconel 718 validate the accuracy of the proposed method for predicting flank wear of the micro tool during micro-milling Inconel 718.

Findings
A new prediction method for flank wear of the micro tool during micro-milling Inconel 718 based on the assumption that the wear volume can be assumed as a cone-shaped body is proposed. Compared with the existing experiment techniques for predicting tool wear during micro-milling process, the proposed method is simple to operate and is cost-effective. The existing finite element investigations on micro tool wear prediction mainly focus on micro tool axial wear depth, which affects size accuracy of machined workpiece seriously.

Originality/value
The research can provide significant knowledge on the usage of finite element method in predicting tool wear condition during micro-milling process. In addition, the method presented in this paper can provide support for studying the effect of tool flank wear on cutting forces during micro-milling process.
Mechanisms of meme propagation in the mediasphere: a system dynamics model
Authors: Perissi Ilaria , Falsini Sara , Bardi Ugo 
Published: October 2018

Purpose
In the age of internet memes spread around the world in very short time, it has been already proved that, in several cases, the mechanism of propagation is very similar to a flu infection. However, this model turns out to be invalid if the spreading is generated by the mass media (TV, radio and the like). This paper aims to explore for the first time this non-viral dynamic (“fallout model”).

Design/methodology/approach
Two different dynamic models were developed to explain the viral and the mass media-powered meme propagations, and both were tested using data from Google Trends.

Findings
Viral propagation is not the only mechanism of meme diffusion. Memes can also diffuse by a “fallout” model, in which the susceptible populations are affected by the meme messages almost simultaneously, as it happens in the physical world for a radioactive fallout or for other poisoning agents.

Originality/value
This study provides a method to determine whether a certain meme has been diffusing by means of its own viral power or has been “planted” as the result of a commercial advertising campaign or a government propaganda operation.
Advertisement recommendation based on personal interests and ad push fairness
Authors: Liu Duen-Ren , Liao Yu-Shan , Chung Ya-Han , Chen Kuan-Yu 
Published: October 2018

Purpose
Online advertisement brings huge revenue to many websites. There are many types of online advertisement; this paper aims to focus on the online banner ads which are usually placed in a particular news website. The investigated news website adopts a pay-per-ad payment model, where the advertisers are charged when they rent a banner from the website during a particular period. In this payment model, the website needs to ensure that the ad pushed frequency of each ad on the banner is similar. Under such advertisement push rules, an ad-recommendation mechanism considering ad push fairness is required.

Design/methodology/approach
The authors proposed a novel ad recommendation method that considers both ad-push fairness and personal interests. The authors take every ad’s exposure time into consideration and investigate users’ three different usage experiences in the website to identify the main factors affecting the interests of users. Online ad recommendation is conducted on the investigated news website.

Findings
The results of the experiments show that the proposed approach performs better than the traditional approach. This method can not only enhance the average click rate of all ads in the website but also ensure reasonable fairness of exposure frequency of each ad. The online experiment results demonstrate the effectiveness of this approach.

Originality/value
Existing researches had not considered both the advertisement recommendation and ad-push fairness together. With the proposed novel ad recommendation model, the authors can improve the ad click-through rate of ads with reasonable push fairness. The website provider can thereby increase the commercial value of advertising and user satisfaction.
Evaluating the role of gamification and flow in e-consumers: millennials versus generation X
Authors: García-Jurado Alejandro , Castro-González Pilar , Torres-Jiménez Mercedes , Leal-Rodríguez Antonio L. 
Published: October 2018

Purpose
This research has three main objectives. First, it examines influence of gamification on the behavioral intention to use an e-commerce platform. Second, it analyzes the role of the flow state given its importance in terms of behavior in online environments. Finally, the study aims to detect and analyze differences between Millennials and Generation X.

Design/methodology/approach
The theoretical basis for this study stems from technology acceptance model. The extended model incorporates gamification and the optimal state of intrinsic motivation, flow state, as additional constructs. An online consumer panel was used to collect data from 253 Spanish Amazon users. A structural equation modeling, partial least squares, is proposed and multi-group moderation was studied.

Findings
Gamification in Millennials has positive and significant indirect effects on behavioral intention through the flow state. In the case of the Generation X, it has been detected that flow interferes in its perception of ease of use. The behavioral intention of using the Web page is directly correlated with the purchase intention. Companies should offer a fun interface to Millennials and an environment easier to use to the Generation X, for gamification to be successful.

Originality/value
This study expands the research scope in gamification by focusing on e-commerce sector, a field where scientific research is still scarcely developed. It emphasizes the importance of flow as mediator. Age differences confirm the need for segmentation when applying gamification and marketing strategies in e-commerce.

Authors: Che Yu , Li Yongqiang , Fam Kim-Shyan , Bai Xuan 
Published: October 2018

PurposeThis study aims to examine the underlying mechanism of buyer–seller ties and salespeople’s performance. Also examined was the moderating effects of the density of the customer network in which the salesperson is embedded.Design/methodology/approachThe study developed a framework incorporating five key variables: strength of ties, network benefits, network density, sales effectiveness and sales revenue. The framework was tested using data from insurance companies in China.FindingsProcess regression and stepwise regression results indicated that information, influence and solidarity benefit will mediate the effects of strength of ties on sales effectiveness both when taken as a set and separately. Information, influence and solidarity benefit will mediate the effects of strength of ties on sales revenue when taken as a set, but only influence will mediate the effect separately. In addition, the positive relationship between strength of ties and solidarity benefit is weaker when network density is high.Practical implicationsSales managers should initiate trainings and workshops about how to obtain high-quality information from customers, improving influencing power and establishing solidarity with customers. Moreover, salespeople should avoid conducting business with a group of customers if they are densely connected to one another.Originality/valueOn the one hand, this study contributes to the underlying mechanism research on buyer–seller ties and sales performance. On the other hand, it contributes to the contingency research on sales performance and the development of social network theory.

Authors: Abdallah Amira E.M. , Mohareb Rafat M. 
Published: October 2018

PurposeThis work aims to synthesize a series of novel acyclic and/or heterocyclic systems, as precursors for dyes with potential antimicrobial activity that could be used for simultaneous dyeing and antimicrobial textile finishing. Thus, a series of novel pyridine, thiophene and pyrazolo[3,4-b]pyridine derivatives were synthesized, and their antimicrobial and textile finishing properties were studied and evaluated.Design/methodology/approachThe synthesis, structure elucidation and antimicrobial activities of the newly synthesized compounds based on 4,4-dicyano-3-phenyl-but-3-enoic acid phenylamide (1) were demonstrated. The minimal inhibitory concentration in μg/mL of the compounds showed significant antimicrobial activity against most of the tested organisms. On the other hand, their spectral characteristics and fastness properties were measured and evaluated. Antimicrobial activities of the dyed fabrics in terms of inhibition zones (mm) were measured and evaluated.FindingsA series of novel heterocyclic compounds (Schemes 1-3) were synthesized based on starting material (1). Compounds (1), 2, 4a, 8a and 9c exhibited comparable or even higher antibacterial activities than the selected standards (ampicillin), while compounds 2, 3c, 3d, 4a and 8b revealed higher antifungal activities than the selected standard (cycloheximide). On the other hand, some dyes showed high antimicrobial evaluation on the dyed fabrics (nylon 66, acetate and polyester) expressed as size (mm) of inhibition zones (Tables I-IV).Practical implicationsResults revealed that many hydrazo and azo derivatives were synthesized from some pyridines and thiophenes. The antimicrobial evaluation and textile finishing of the newly synthesized products revealed significant and potent values of antimicrobial activity.Originality/valueAll the synthesized compounds were novel and most of them exhibited higher antimicrobial activities than the selected standards antibiotics, thus are valuable for simultaneous dyeing and antimicrobial functional finishing of textile fabrics.
