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 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.

Abstract

Purpose

Acceptance and use of mobile shopping as the preferred shopping medium is becoming the new normal today. The proliferation of mobile shopping practices follows unsteady growth patterns in different countries. Despite challenges of price, quality and privacy matters, young consumers still lead the race to engage in mobile shopping activity in developing countries. This research investigates the determinants that either support or hinder the mobile shopping intentions of aspirant young consumers in Pakistan.

Design/methodology/approach

The present research applies a consumer-centric approach to the technology adoption framework to unearth the behavioral patterns of these young consumers in Pakistan. Employing the structural equation modeling technique, this research examines the significant effect of structural assurance, perceived risk, trust and various unified theory of acceptance and use of technology (UTAUT) model constructs on behavioral intention to engage in mobile shopping.

Findings

This research examines the significant effect of structural assurance, perceived risk, trust and various UTAUT model constructs on behavioral intention to engage in mobile shopping. Results also demonstrate a significant moderating effect of structural assurance and prior shopping experience on the relationship between perceived risk, trust and mobile shopping intentions. Further, the mobile shopping patterns for the male and female segment indicate a significant difference for perceived risk, trust structural assurance and social influence. The research contributes to the growing body of knowledge which advocates the application of consumer-centric customized model approach to explore various factors that either facilitate or impede the adoption of mobile shopping in a developing economy.

Research limitations/implications

The study validates the need to enforce structural assurance mechanism for facilitating mobile shopping in a developing country. It also offers practical implications for online businesses and marketers striving to attract and retain more mobile customers.

Practical implications

The study offers practical implications for online businesses and marketers striving to attract and retain more mobile customers.

Originality/value

This study offers fresh insights about driving elements and impediments of mobile shopping behavioral intentions. Structural assurance and prior shopping experience appear to influence the mobile shopping behavior through direct and indirect effect.
