Abstract

Purpose

Sustainable machining is a global consensus and the necessity to cope up the serious environmental threats. Minimum quantity lubrication (MQL) and nanofluids-based MQL(NFMQL) are state-of-the-art sustainable lubrication modes. The purpose of this study is to investigate the effect of process parameters, such as feed rate, depth of cut and cutting fluid flow rate, on temperature and surface roughness of the manufactured pieces during face milling of the AISI D2 steel.

Design/methodology/approach

A statistical technique called response surface methodology with Box–Behnken Design was used to design experimental runs, and empirical modeling was presented. Analysis of variance was carried out to evaluate the model’s accuracy and the validation of the applied technique.

Findings

A comprehensive analysis revealed the superiority of implementing NFMQL in comparison to MQL within the levels of process parameters. The comparison has shown a significant reduction of temperature under NFMQL at the tool-workpiece interface from 16.2 to 34.5 per cent and surface roughness from 11.3 to 12 per cent.

Practical implications

This research is useful for practitioners to predict the responses in workshop and select appropriate cutting parameters. Moreover, this research will be helpful to reduce the resource which will ultimately save energy consumption and cost.

Originality/value

To cope with the industrial challenges and tribological issues associated with the milling of AISI D2 steel, experiments were conducted in a distinct machining mode with innovative cooling/lubrication. Until now, few studies have addressed the key lubrication effects of Al2O3-based nanofluid on the machinability of D2 steel under NFMQL lubrication condition.

Abstract

Purpose

In the era of knowledge economy, the significance of intellectual capital has been increasing globally. Similarly, recent studies have focused on the importance of green intellectual capital in mitigating environmental degradation. However, only a few studies have analysed green intellectual capital and its impacts in the specific case of Pakistan. Hence, this study aims to investigate the effects of green intellectual capital on green innovation adoption in Pakistan’s manufacturing small and medium-size enterprises (SMEs).

Design/methodology/approach

We used a data sample of 235 SMEs, gathered from the four manufacturing sectors of Pakistan including: textile, chemical, pharmaceutical and steel and analysed using a multiple regression analysis approach.

Findings

The empirical results of this research indicate that green human capital and green structural capital significantly increase green innovation adoption. However, it must be noted that green relational capital has a positive but insignificant impact on green innovation adoption in manufacturing SMEs in Pakistan.

Originality/value

The findings and recommended policy measures of this study are important for the managers of manufacturing SMEs and policymakers to mitigate environmental destruction and achieve sustainable development through green intellectual capital.

Abstract

Purpose

This study aims to investigate individual-related consequences of workplace bullying among the health-care section. Specifically, this study examined the mediating role of burnout between workplace bullying and nurses’ well-being. Moreover, passive avoidant leadership is examined as a conditional variable between workplace bullying and burnout.

Design/methodology/approach

This study collected data from 314 nurses working in various hospitals through a questionnaire-based survey using Google Form in two waves.

Findings

Structural equation modeling confirmed the negative effect of workplace bullying on nurses’ well-being, whereas burnout mediates this relationship. In addition, passive avoidant leadership was identified as a conditional variable that strengthens the positive association between workplace bullying and burnout.

Research limitations/implications

Although data for the study were collected in two waves, still cross-sectional design limits causality.

Practical implications

This study suggests management to focus on developing and implementing counter-bullying rules to avoid the adverse consequences of workplace bullying (e.g. capital loss, recruitment costs, burnout, well-being, etc.). In addition, leaders/supervisors must be trained to fulfill their responsibilities to reduce negative consequences.

Originality/value

Studies on workplace bullying in high-power distance cultures are scant. Therefore, drawing upon conservation of resource theory, to the best of the authors’ knowledge, this is the first study that has investigated the moderating role of passive avoidant leadership on the association between workplace bullying and burnout.

Abstract

Purpose

The purpose of this study is to critically understand and find out the socio-political role of the Acehnese ulamas (Muslim scholars) in solving and coping with social issues faced by contemporary Acehnese society.

Design/methodology/approach

This study was conducted in the province of Nanggroe Aceh Darussalam, especially in the districts of Aceh Utara, Pidie, Aceh Besar, Aceh Selatan and Aceh Timur. The locations were chosen based on the consideration of the objective conditions that many ulamas were dwelling and could easily be found in these areas. Besides, the locations are historically believed as the origins of the Acehnese that are so diverse. In addition, a large number of social problems frequently arose within those regions. The subjects of this research study were a number of community determined by purposive sampling technique. The instruments used for the data collection in this research were observation, in-depth interview and library study; and interpretative understanding was also used to analyze the data.

Findings

The existence of the Acehnese ulamas represents the government’s recognition to word the traditional institutional in Aceh. However, some people think that institutions are used by the government to exploit ulama as the mediator between the government and the society. For the Acehnese ulamas, the institution could be used to consolidate their power for the benefit of the people.

Originality/value

The various theories discussed are considered the framework and guidance for this study, especially in terms of data collection and data analysis. The new theories and relevant references will also possibly be added to the following study.

Abstract

Purpose

This study unpacks the relationship between violations of organizational promises, as perceived by employees and their job performance, considering the mediating effects of job-related anxiety and moderating effects of psychological contract type.

Design/methodology/approach

Multi-source, multi-wave data were collected from employees and their supervisors in Pakistan.

Findings

Feelings of organizational betrayal may reduce job performance due to the higher anxiety that employees experience in their daily work. This mediating role of enhanced job-related anxiety in turn is stronger to the extent that employees believe that their psychological contract contains relational obligations but weaker when it contains transactional obligations.

Practical implications

The study gives organizational decision makers pertinent insights into how they can mitigate the risk that employees who are angry about broken organizational promises stay away from performance-enhancing work activities, namely, by managing the expectations that come along with psychological contracts. In so doing, they can avoid imposing dual harms on employees, from both a sense that they have been betrayed and the risk of lower performance ratings.

Originality/value

This study offers expanded insights into the process that underpins the translation of psychological contract violations into diminished job performance, by pinpointing the simultaneous roles of experienced job-related anxiety and beliefs about employer obligations.

Abstract

Purpose

In the modern business world, the main focus of the organizations is to improve the quality of the products and minimize the wastage of raw material. Keeping in view the green theory and improve the efficiency of the organization, the focus of the current study is to investigate the relationship between total quality management (TQM) and green innovation (GI), and examine how TQM practices can facilitate firms to achieve GI objectives. Corporate social responsibility (CSR) is also an important factor for organizations, and this study also focuses on the mediating role of CSR between the relationship of TQM and GI.

Design/methodology/approach

This is an empirical study. Data were gathered from the top management of 355 SMEs working in Pakistan through a questionnaire survey; the PLS-SEM approach was used to analyse the data.

Findings

Results of the study show that TQM has significant impacts on two aspects of GI namely green product innovation and green process innovation. Moreover, results also reveal that CSR partially mediates the relationship between TQM and GI.

Research limitations/implications

This study is limited to manufacturing SMEs and future research should test this model on non-manufacturing sector too. The findings of the study provide significant roadmap to the management of small and medium-sized manufacturing firms that how they can reduce wastage and improve the product and process innovation in their organizations through TQM and CSR.

Originality/value

This study contributes to bridging research gaps in the literature and advances how TQM, directly and indirectly, help firms improve green innovation via mediating roles of CSR.

Abstract

Purpose

The purpose of this paper is to examine the impact of different food choice motives on attitude and, subsequently, the impact of attitude, subjective norm and perceived behavioural control on the purchase intention of Pakistani ethnic food, based on the food choice motives theory and the theory of planned behaviour.

Design/methodology/approach

Using an intercept survey, data were collected from 559 local tourists coming from different areas of the country, who visited Swat, Gilgit and Muree regions of Pakistan, and the data were analysed using SmartPLS software.

Findings

In terms of direct effects, mood, familiarity, natural content and price were found to be significant predictors for attitude, whereas attitude, subjective norm and perceived behavioural control were found to positively affect intention to purchase Pakistani ethnic food. In addition, attitude was found to serve as a mediator for the relationships between mood, familiarity, sensory appeal and price on purchase intention.

Originality/value

This study has shed some light on the food choice behaviour of domestic tourists opting for their own local cuisine in Pakistan, which is under-represented in the tourism and food research literature. We also tested an integrated model of food choice motives and the theory of planned behaviour in modelling purchase intention in the tourism perspective. The present study also adds to the existing literature on mediation by modelling attitude as a mediator between food choice motives and purchase intention in the context of a developing country.

Abstract

Purpose

The main aim of this study is to investigate the impact of climate change and water salinity on farmer’s income risk with future outlook mitigation. Salinity and climate change are a threat to agricultural productivity worldwide. However, the combined effects of climate change and salinity impacts on farmers' income are not well understood, particularly in developing countries.

Design/methodology/approach

The response-yield function and general maximum entropy methods were used to predict the impact of temperature, precipitation and salinity on crop yield. The target minimization of total absolute deviations (MOTAD)-positive mathematical programming model was used to simulate the impact of climate change and salinity on socioeconomic and environmental indicators. In the end, a multicriteria decision-making model was used, aiming at the selection of suitable climate scenarios.

Findings

The results revealed that precipitation shows a significantly decreasing trend, while temperature and groundwater salinity (EC) illustrate a significantly increasing trend. Climate change and EC negatively impact the farmer's income and water shadow prices. Maximum reduction in income and water shadow prices was observed for A2 scenario (−12.4% and 19.4%) during 2050. The environmental index was the most important, with priority of 43.4% compared to socioeconomic indicators. Subindex amount of water used was also significant in study area, with 28.1% priority. The technique for order preference by similarity to ideal solution ranking system found that B1 was the best climatic scenario for adopting climate change adaptation in the research region.

Originality/value

In this study, farmers' income threats were assessed with the aspects of different climate scenario (A1, A1B and B1) over the horizons of 2030, 2040 and 2050 and three different indicators (economic, social and environmental) in Northwestern region of Pakistan. Only in arid and semiarid regions has climate change raised temperature and reduced rainfall, which are preliminary symptoms of growing salinity.

Abstract

Purpose

The main purpose of this study is to analyze the heat transfer phenomena in a dynamically bulging enclosure filled with Cu-water nanofluid. This study examines the convective heat transfer process induced by a bulging area considered a heat source, with the enclosure's side walls having a low temperature and top and bottom walls being treated as adiabatic. Various factors, such as the Rayleigh number (Ra), nanoparticle volume fraction, Darcy effects, Hartmann number (Ha) and effects of magnetic inclination, are analyzed for their impact on the flow behavior and temperature distribution.

Design/methodology/approach

The finite element method (FEM) is employed for simulating variations in flow and temperature after validating the results. Solving the non-linear partial differential equations while incorporating the modified Darcy number (10−3Da ≤ 10−1), Ra (103Ra ≤ 105) and Ha (0 ≤ Ha ≤ 100) as the dimensionless operational parameters.

Findings

This study demonstrates that in enclosures with dynamically positioned bulges filled with Cu-water nanofluid, heat transfer is significantly influenced by the bulge location and nanoparticle volume fraction, which alter flow and heat patterns. The varying impact of magnetic fields on heat transfer depends on the Rayleigh and Has.

Practical implications

The geometry configurations employed in this research have broad applications in various engineering disciplines, including heat exchangers, energy storage, biomedical systems and food processing.

Originality/value

This research provides insights into how different shapes of the heated bulging area impact the hydromagnetic convection of Cu-water nanofluid flow in a dynamically bulging-shaped porous system, encompassing curved surfaces and various multi-physical conditions.

Abstract

Purpose

This study aims to empirically examine the knowledge, social and religious factors effecting the intention to receive COVID-19 vaccination while considering the mediating role of attitude towards COVID-19 vaccination. The research explores how the Islamic ideologies shape Muslims’ knowledge, social and religious beliefs towards COVID-19 vaccination acceptance or refusal.

Design/methodology/approach

Theoretically, the study is based on the functional theory of attitudes. The model of the study is comprised of nine variables explaining the attitude and intention towards COVID-19 vaccination. Among nine variables, perceived Islamic religiosity, perceived behavioural control and Halal consciousness among Muslims are explained through the value-expressive function of attitude. Furthermore, the perceived risk of COVID-19, the perceived side effect of COVID-19 vaccination and the perceived efficacy of COVID-19 vaccination are considered in the model based on the utility function of attitude. Moreover, social influence for COVID vaccination, subjective norms and group conformity are abstracted from the social-adjustive function of attitude. This study used a quantitative survey research method to test the hypotheses. A total of 1,000 questionnaires were distributed to non-vaccinated Muslim respondents from five cities in Pakistan. The structural equation modelling (SEM) technique was used to test the relationship among the variables in the proposed model. The partial least square-SEM method explained the variances in the dependent variables. Moreover, to test the structure of data, different statistical tests, including exploratory factor analysis (EFA), factor loadings and average variance extracted, were used with the help of Statistical Package for the Social Sciences (SPSS) and analysis of a moment structures (AMOS) 23.0 version.

Findings

Results for direct effect showed a significant negative effect of Islamic religiosity, perceived behavioural control, halal consciousness, perceived side effect of COVID-19 vaccination, social influence, subjective norm and group conformity on attitude towards COVID-19 vaccination. In contrast, insignificant results showed no relationship of perceived risk from COVID-19 infection and perceived efficacy of COVID-19 vaccination with attitude towards COVID-19 vaccination. Results for mediating effect showed the significant negative mediating effect of attitude towards COVID-19 vaccination between Islamic religiosity, perceived behavioural control, halal consciousness, perceived side effect, social influence, subjective norm, group conformity and intention to receive COVID-19 vaccination. While results showed the insignificant mediation of attitude towards COVID-19 between perceived risk from COVID-19 infection, perceived efficacy of COVID-19 vaccination and intention to receive COVID-19 vaccination.

Research limitations/implications

Further studies are required to compare the attitude and intention among the temporary refusal group (those who will consider vaccination the future) and the permanent refusal group (those who will not consider vaccination the future). Comparing Muslim and non-Muslim groups can also explain differences in attitude and intention towards COVID-19 vaccination.

Originality/value

The area of acceptance and refusal of COVID-19 vaccination has been given limited attention in academic literature. Theoretically, this research has proposed a well-defined model to explain the attitude of Muslims towards COVID-19 vaccination. This model can helpf predict the attitude and intentions of Muslims towards vaccination or medicines. Moreover, this research is a unique contribution for the vaccination brands to consider the discussed factors before launching their brand in Muslim countries.
