Abstract

Purpose

The purpose of this study is to examine the simultaneous effects of Hafnium particles and partially submerged metallic particles for the flow of bi-phase coupled stress fluid over an inclined flat plane.

Design/methodology/approach

An unflinching free stream flow that stretches far from the surface of the plane with the possibility of containing some partially submerged metallic particles is considered. Innovative model has been proposed and designed using Runge–Kutta–Fehlberg method.

Findings

The findings show that the drag force resists the couple stress fluid, whereas the Newtonian flow is supported by increasing the velocity. For both types of flows, movement of the particle is retarded gradually against the drag force coefficient.

Originality/value

To the best of the authors’ knowledge, this model is reported for the first time.

Abstract

Purpose

This study aims to investigate the outcomes of customers’ co-creation experience in a realistic and routinely performed co-creation setting, a restaurant. To fulfill this purpose, the current study links the branding literature to hospitality research and offers a novel framework by incorporating customers’ co-creation experience, customer brand engagement, emotional brand attachment and customer satisfaction in an integrated research model.

Design/methodology/approach

Data were collected from 421 diners at Chinese hotpot restaurants via a self-administered questionnaire. The reliability and convergent and discriminant validities were established through confirmatory factor analysis, and then hypotheses were tested through structural equation modeling.

Findings

This study demonstrates that customers’ co-creation experience with a restaurant brand positively impacts customer brand engagement, emotional brand attachment and customer satisfaction. In addition, current study examines these relational paths at the dimensional level by taking the co-creation experience and customer brand engagement as multidimensional constructs. The resulting in-depth investigation reveals that the hedonic, social and economic experience dimensions of co-creation experience positively influence customer satisfaction, emotional brand attachment and customer brand engagement’s buying, referring, influencing and feedback dimensions.

Practical implications

This study helps relationship and brand managers better understand customer experience in co-creation settings and paves the way for managers to devise engagement strategies.

Originality/value

The current study marks an initial attempt to delineate the outcomes of customers’ co-creation experience in a realistic co-creation setting. Furthermore, the study is first of its kind that investigates the relationship of co-creation experience and customer brand engagement at the dimensional level.

Abstract

Purpose

Drawing upon the theoretical underpinning of knowledge worker productivity, this study aims to examine the relationship between abusive supervision and knowledge management (KM) process (creation, application and sharing of knowledge) and its impact on the knowledge worker productivity in knowledge-intensive organizations.

Design/methodology/approach

Hypothesis were tested through PROCESS Macro in IBM SPSS v.26 on a sample of 204 employees working in banking sector of Pakistan. Confirmatory factor analysis was conducted to test the model fitness through AMOS v. 26.

Findings

The results showed that the relationship between abusive supervision and KM process (creation, application and sharing of knowledge) is negative and highly significant, i.e. greater the abusive supervision in the banking sector, the lower is the engagement in KM processes. Furthermore, there is a positive and highly significant relationship between the KM process and knowledge worker productivity. Finally, the study indicates the negative impact of abusive supervision on the knowledge worker productivity through the mediating mechanism of knowledge management processes.

Research limitations/implications

A key limitation is that the study is cross-sectional, and the findings may only be generalizable to developing countries context.

Originality/value

Previous studies have focused on supervisor–employee relationship but not in the context of knowledge worker productivity. This article fulfills this gap through understanding the impact of abusive supervision on the knowledge worker productivity in relation to KM processes (knowledge creation, sharing and application) by drawing upon the theoretical underpinning of knowledge worker productivity.

Abstract

The tourist experience has matured in its body of literature, but researchers still debate the best way to measure and define the concept. The purpose of this paper is to analyze and compare memorable and on-site tourist experiences from theoretical, empirical, and methodological perspectives. A review of the literature is used to identify and describe the next evolutionary research step which is the quality-of-life (QOL) aspect of tourism experiences. It is argued that the evolving focus on QOL attributes is fueled by the theories and concepts of service-dominant logic. The paper argues that value (co)created on all sides of the equation (e.g., customer or company) must be considered when carrying out research. The paper also finds that different value outcomes for the individual customer occur in both on-site and memorable experience contexts. The findings contest an earlier theoretical argument, suggesting that memorable tourist experiences provide more value than on-site tourist experience.

Abstract

Purpose

The purpose of this paper is twofold: first, to estimate the water demand elasticities using a parametric linear programming (LP) model to provide an insight into the accurate and flexible pricing policy of irrigation water in the Jordan Valley; and second, to highlight key risk aspects, related to water demand, which are likely to impact the community.

Design/methodology/approach

A parametric LP model was used in this research. Primary and secondary data were collected.

Findings

Results revealed that the demand elasticity is high in Spring and Summer than in Fall and Winter, meaning that during Spring and Summer farmers are willing to forgo larger amounts of water than in other months. This is because of areas planted during Spring seasons are much less than those of Autumn and Winter.

Practical implications

The Jordan Valley suffers from water scarcity risk, and consequently the area to be planted is not fully utilized, leading to lower cropping intensities. Responsible authorities in Jordan need to address these issues and propose proper solutions in order to reduce further escalation of this risk and subsequent impact on local communities. Insight into the value of water demand elasticities is essential to support and mitigate policy decision making under risk conditions, concerning investments in water supply systems; investments in the water distribution and irrigation systems; efficient allocation of water with competing sectors; setting water pricing and tariffs; setting cost recovery mechanisms, and the risks encountered under lack of mitigated policy decision making.

Originality/value

This is one of few studies that addresses in detail using a parametric LP model the issue of water scarcity, related risks and subsequent impact on society in Jordan. It is expected to help policy and decision makers better formulate future estimates and demand which subsequently reduce related risks.

Abstract

Purpose

The productivity of knowledge workers is crucial not only for organizational innovation and competitiveness but also for sustainable development. In the context of knowledge-intensive firms, implementation of knowledge management is likely to increase knowledge worker productivity. Therefore, the purpose of this paper is to examine the influence of knowledge management on knowledge worker productivity.

Design/methodology/approach

A research framework on the effects of knowledge management processes on knowledge worker productivity is established and empirically tested with data from 336 knowledge workers at five mobile network operator companies in Pakistan.

Findings

The results indicate that knowledge creation and knowledge utilization impact knowledge worker productivity positively and statistically significantly. However, knowledge sharing does not have statistically significant impact on knowledge worker productivity. Demographic factors (gender, managerial position and formal education level) do not moderate the relationship between knowledge management and knowledge worker productivity statistically significantly.

Research limitations/implications

The key limitations are the cross-sectional nature of the data and the geographic limitation to telecom companies in Pakistan.

Practical implications

Irrespective of gender, education and managerial position, implementation of knowledge management can increase knowledge worker productivity. Therefore, knowledge management practices should be implemented to enhance the knowledge worker productivity via fostering the knowledge worker’s engagement in and propensity to knowledge management processes.

Originality/value

This study is among the first to examine the likely influence of knowledge management on the productivity of knowledge workers conclusively while controlling for three individual demographic factors. This study also addresses the effectiveness of knowledge management in the little-explored cultural context of Pakistan.

Abstract

Purpose

The purpose of this paper is to analyze the historical gas allocation pattern for seeking appropriate arrangement and utilization of potentially insufficient natural gas supply available in Pakistan up to 2030.

Design/methodology/approach

This study presents Markov chain-based modeling of historical gas allocation data followed by its validation through error evaluation. Structural prediction using classical Chapman–Kolmogorov method and varying-order polynomial regression in the historical transition matrices are presented.

Findings

Markov chain model reproduces the terminal state vector with 99.8 per cent accuracy, thus demonstrating its validity for capturing the history. Lower order polynomial regression results in better structural prediction compared with higher order ones in terms of closeness with Markov approach-based prediction.

Research limitations/implications

The data belongs to a certain geographic region with specific gas demand and supply profile. The proposition may be tested further by researchers to check the validity for other comparable structural predictions/analyses.

Practical implications

This study can facilitate policy-making in the field of natural gas allocation and management in Pakistan specifically and other comparable countries generally.

Originality/value

Two major literature gaps filled through this study are: first, Markov chain model becomes stationary when projected using Chapman–Kolmogorov relation in terms of a fixed, average transition matrix resulting in an equilibrium state after a finite number of future steps. Second, most of the previous studies analyze various gas consumption sectors individually, thus lacking integrated gas allocation policy.

Abstract

Purpose

This study aims to consolidate finds about corporate social responsibility (CSR) by conducting a meta-analysis. CSR is a topic present in both academic and practitioner discussions. Research has been conducted in different countries and contexts, using diverse methodological approaches. Consequently, there are different views about CSR and conflicting results.

Design/methodology/approach

This paper conducted a meta-analysis to analyse the constructs that are antecedents and consequences of CSR. This paper has also tested the moderating effects of theoretical, methodological and economic variables. The data analysis involved 66 studies, which generated 385 observations and an accumulated sample of 19,817 respondents.

Findings

The findings indicate that environmental concerns, market orientation and stakeholder pressure are the most relevant CSR antecedents. On the other hand, CSR has the strongest effects on organisational commitment, non-financial performance and customer purchasing intention. Also, firm size and cultural orientation were partially significant moderators on the relationships between organisational commitment, CSR and financial performance.

Originality/value

The meta-analytical approach allows for more accurate effect size estimations for each relationship analysed, as the meta-analytic method jointly evaluates the results produced by a great variety of studies performed in different contexts, making it possible to draw more accurate conclusions.

Abstract

Purpose

This study aims to investigate the effect of two-dimensional Darcy-Forchheimer flow over second-grade fluid with linear stretching. Heat transfer through convective boundary conditions is taken into account.

Design/methodology/approach

Nonlinear coupled governing equations are tackled with a homotopy algorithm, while for numerical computation the computer software package BVPh 2.0 is used. The convergence analysis is also presented for the validation of analytical and numerical results.

Findings

Valuation for the impact of key parameters such as variable thermal conductivity, Dufour and Soret effects and variable magnetic field in an electrically conducted fluid on the velocity, concentration and temperature profiles are graphically illustrated. It is observed from the results that temperature distribution rises by Dufour number whereas concentration distribution rises by Soret number. The Forchheimer number and porosity parameter raise the skin friction coefficient. The permeable medium has a vital impact and can help in reining the rate of heat transfer.

Practical implications

The permeable medium has a vital impact and can help in reining the rate of heat transfer.

Originality/value

To the best of the authors’ knowledge, this study is reported for the first time.

Abstract

Purpose

The rising proportion of internet users in Sub-Saharan Africa and the lack of analytical techniques, as decision support systems, in choosing among alternative internet service providers (ISPs) by consumers underpin this study. The purpose of this paper is to propose an approach for evaluating high-speed internet service offered by ISPs in a sub-Saharan African country.

Design/methodology/approach

Using a sample size of 150, pairwise comparisons of two ISPs along five criteria of cost, usability, support, reliability and speed were performed by ten person groups of university students working in various organizations in Ghana and undertaking an online Six Sigma Course. Geometric means were employed to aggregate the scores in 15 groups, and these scores were then normalized and used as input into an analytical hierarchy process grid.

Findings

The results show that consumers of internet services highly emphasize the cost attribute of internet provision in their decision making. On the other hand, it was realized that consumers least emphasize the support provided by ISPs in their decision making among alternative ISPs.

Originality/value

This study has sought to provide an analytical framework for assessing the quality of service provided by alternative ISPs in a developing economy’s context. The evaluating criteria in this framework also reveal the key consumer requirements in internet service provision in a developing economy’s environment. This, to a large extent, will inform the marketing strategies of existing ISPs in Ghana as well as prospective ones intending to enter the Ghanaian market. Besides, the National Communication Authority, a regulator of communication services provision in Ghana, will be informed about the performances of the ISPs along five performance criteria. This is expected to aid in their regulatory functions.
