Abstract
Purpose
This paper aims to examine the consequences for innovative work behavior (IWB) of top-down knowledge hiding – that is, supervisors’ knowledge hiding from supervisees (SKHS). Drawing on social learning theory, the authors test the three-way moderated-mediation model in which the direct effect of SKHS on IWB is first mediated by self-efficacy and then further moderated by supervisor and supervisee nationality (locals versus foreigners).
Design/methodology/approach
The authors collected multi-sourced data from 446 matched supervisor-supervisee pairs working in a diverse range of organizations operating in the Kingdom of Saudi Arabia. After initial data screening, confirmatory factor analysis was conducted to test for the factorial validity of the used measures with AMOS. The hypothesized relationships were tested in regression analysis with SPSS.
Findings
Results showed that SKHS had both direct and mediation effects, via the self-efficacy mediator, on supervisee IWB. The mediation effect was further moderated by supervisor and supervisee nationality (local versus foreigners), which highlighted that the effect was stronger for supervisor–supervisee pairs that were local-local or foreigner-foreigner than for pairs that were local-foreigner or foreigner-local.
Originality/value
This study contributes to both knowledge hiding and IWB literature and discusses the useful theoretical and practical implications of the findings.

Abstract
Purpose
Drawing on the self-consistency theory, this study aims to test a model where employees' supervisor-based self-esteem (SBSE) is positively related to their promotive and prohibitive voice and mediate the positive relationship between leader–member exchange social comparison (LMXSC) of an employee's promotive and prohibitive voice, but only for local rather than migrant workers.
Design/methodology/approach
To test the study hypotheses, multi-source data were collected from 341 matched supervisor–supervisee dyads working in a diverse range of organizations in the Kingdom of Saudi Arabia.
Findings
As predicted, employees' SBSE is positively related to their promotive and prohibitive voice and mediates a positive relationship between their LMXSC and their promotive and prohibitive voice, but only for local workers. The study findings support the self-consistency theory perspective on LMX and provide new insight into the “dark side” of migrant working – a lack of voice.
Originality/value
This study responds to calls for more research that explores the roles played by macro-environmental factors on employees' voice. Implications for theory and practice are discussed.

Abstract
Purpose
Numerous companies have launched brand pages (BPs) on social networking sites to enhance customer-brand communication, cultivate the customer-brand relationship and promote brand loyalty. This study aims to investigate how BP affordances support social commerce.
Design/methodology/approach
The study devises a theoretical model linking the proposed BP affordances (visibility, selectivity, persistence and interactivity) to three customer values (relationship quality, brand experience and smart shopping feeling [SSF]) to encourage brand loyalty and BP endorsement on the part of the customer.
Findings
Data collected from 591 respondents support all proposed hypotheses. The model explains high variances in brand loyalty and BP endorsement, indicating that relationship quality plays a more salient role in producing brand loyalty, while SSF plays a more important role in eliciting BP endorsement.
Originality/value
The study is unique in four ways. First, drawing on the lens of affordance, it proposes specific affordances for BPs and offers empirical results for their applicability. Second, by incorporating CDL into the research model, it illuminates the high explanatory power of these proposed BP affordances on the three customer values. Integrating the S-O-R model with the affordance perspective and CDL provides a more complete picture of the BP phenomenon. Third, it extends the reach of existing work by examining BP endorsement in social media as a dependent variable beyond brand loyalty, with SSF included as another source of values to shed more light on the relationships depicted in the model. Fourth, by taking trait competitiveness into account, it sheds further light on relationships between customer values and BP endorsement.

Abstract
Purpose
This study aims to examine the moderated-mediation effects of employees’ Islamic work ethic (IWE) on their promotive and prohibitive forms of constructive voice behaviors through the integrated frameworks of social identity theory and self-consistency theory.
Design/methodology/approach
Using two-source data collection from employees and supervisors, data were collected from 217 participants working in various companies in the Kingdom of Saudi Arabia. After initial data screening, a confirmatory factor analysis was conducted to test for the factorial validity of the used measures with AMOS. The hypothesized relationships were tested in the PROCESS macro for SPSS.
Findings
The results of this study supported the integration of social identity theory with self-consistency theory in explaining the indirect effects of employees’ IWE on their promotive and prohibitive forms of constructive voice behaviors through the mediation of moral identity. Furthermore, this study also indicated that the indirect effect was conditional on the employees’ perceptions of perceived voice opportunity, which significantly moderated the relationship between their moral identity and their prohibitive voice. However, no such effect was recorded for promotive voice.
Originality/value
This study is the first that explains how and when employees’ IWE leads them to exhibit promotive and prohibitive voice behaviors through the mediation of moral identity and the moderation of perceived voice opportunity. Thus, this study contributes to the IWE, moral identity and employee voice literature by addressing questions with useful theoretical and managerial implications for employees’ promotive and prohibitive forms of constructive voice behaviors in the workplace.

Abstract
Purpose
Drawing on social identity theory and prosocial behaviour research, this study explores how people's integration of their offline and online social activities through Facebook cultivates their Facebook citizenship behaviour (FCB). It also offers further insight into the underlying mechanism of offline and online social activity integration - FCB relation by investigating people's social identification with their offline and online social groups as possible mediators.
Design/methodology/approach
Based on social identity theory (SIT) literature, community citizenship behaviour and offline-online social activity integration through Facebook, we developed a conceptual model, which was empirically tested using data from 308 Facebook users
Findings
The results confirm that the participants' offline-online social activity integration via Facebook is positively linked to their FCB. Further, the integration of offline and online social activity through Facebook positively affects how a person identifies with their offline and online social groups, which in turn causes them to display FCB. In addition, offline/online social identification mediates the integration – FCB relation.
Practical implications
In practice, it is interesting to see people's tendency towards altruistic behaviours within groups they like to associate themselves with. Those who share their Facebook network with their offline friends can use such network to seek help and support.
Originality/value
From a theoretical perspective, unlike past research, this study examines how individuals' offline-online social activity integration via Facebook helps them associate with groups. In addition, this study investigates social identification from an offline and online perspective.

Abstract
Purpose
The study advances research on the high-performance work system (HPWS) and innovation performance (IP) linkage by empirically analyzing the serial mediation of human resource flexibility (HRF) and knowledge absorptive capacity (KAC). Previous research on the HPWS–IP linkage underscores the presence of a “black box.” Therefore, the present study aims to unravel the underexplored HPWS–IP relationship through HRF and KAC mediation in the context of the hotel industry.
Design/methodology/approach
Survey-based time-lagged data were collected from 303 mid-level managers in the hotel industry. Structural equation modeling (SEM) using Smart-PLS 4 was used to test hypothesized relationships.
Findings
The results reveal that HPWS has a significant positive direct relationship with innovation performance, human resource flexibility and knowledge absorptive capacity. Further, both human resource flexibility and knowledge absorptive capacity also serially mediate the HPWS–IP linkage.
Practical implications
The results of the study provide useful insights into the hotel industry in Pakistan by offering empirical evidence that building HPWS in the hotel sector can lead to increased human resource flexibility and enhanced knowledge absorptive capacity, ultimately contributing to improved innovation performance.
Originality/value
Notably, human resource flexibility and knowledge absorptive capacity together as dynamic capabilities represent a novel contribution rarely discussed in the literature, particularly their role as serial mediators between HPWS–IP relationships within the hotel industry.

Abstract
Purpose
The present work is devoted to investigating the sensitivity analysis of the electroosmotic peristaltic motion of non-Newtonian Casson fluid with the effect of the chemical reaction and magnetohydrodynamics through the porous medium. The main focus is on flow efficiency quantities such as pressure rise per wavelength, frictional forces on the upper wall and frictional forces on the lower wall. This initiative is to bridge the existing gap in the available literature.
Design/methodology/approach
The governing equations of the problem are mathematically formulated and subsequently simplified for sensitivity analysis under the assumptions of a long wavelength and a small Reynolds number. The simplified equations take the form of coupled nonlinear differential equations, which are solved using the built-in Matlab routine bvp4c. The response surface methodology and artificial neural networks are used to develop the empirical model for pressure rise per wavelength, frictional forces on the upper wall and frictional forces on the lower wall.
Findings
The empirical model demonstrates an excellent fit with a coefficient of determination reaching 100% for responses, frictional forces on the upper wall and frictional forces on the lower wall and 99.99% for response, for pressure rise per wavelength. It is revealed through the sensitivity analysis that pressure rise per wavelength, frictional forces on the upper wall and frictional forces on the lower wall are most sensitive to the permeability parameter at all levels.
Originality/value
The objective of this study is to use artificial neural networks simulation and analyze the sensitivity of electroosmotic peristaltic motion of non-Newtonian fluid with the effect of chemical reaction.

Abstract
Purpose
The purpose of this paper is to fabricate and investigate sensing properties of a novel, flexible resistive tensile load cells based on multi-walled carbon nano-tubes (MWCNTs)/rubber composites. The use of carbon nanotubes makes it very attractive for being used as sensors.
Design/methodology/approach
On thin rubber substrate, MWCNTs powder was deposited and pressed at elevated temperature. Two types of samples were prepared: first sample was made by depositing MWCNTs suspension in water on the substrate, then the sample was dried at room temperature; the second sample was prepared by applying dry MWCNTs powder directly on the substrate.
Findings
The resistances of the cells made from wet MWCNT powder are much lower than those made with dry powder. It was found that the fabricated load cells were highly sensitive to the force and showed good repeatability. The resistance of the flexible resistive tensile MWCNTs/rubber composite load cells increased 1.37 times, on average, with the increasing force (up to 0.045 N). The sensitivity of the cells was equal to 142 N-1.
Practical implications
The device fabrication method used here provides a simple, less expensive and effective approach for preparing resistive tensile load cells.
Originality/value
A novel, flexible resistive tensile load cells using MWCNTs/rubber composites have been successfully fabricated and investigated. MWCNTs, in dry and wet form, have been deposited on thin rubber substrates by adopting a very simple and inexpensive technique.
