Abstract

Purpose

This study aims to enhance the lubrication performance of thrust bearings. The influence of columnar convex–concave compound microtexture on bearing performance is investigated

Design/methodology/approach

Based on the compound microtexture model of thrust bearings, considering surface roughness and turbulent effect, the variation of lubrication characteristics with the change in the compound microtexture parameters is studied.

Findings

The results indicate that, compared with circular microtexture, the maximum pressure of compound microtexture of thrust bearings increases by 7.42%. Optimal bearing performance is achieved when the internal microtexture depth is 0.02 mm. Turbulent flow states and surface roughness lead to a reduction in the optimal depth. The maximum pressure and load-carrying capacity of the bearing decrease as the initial angle increases, whereas the friction coefficient increases with the increase in the initial angle. The lubrication performance is best for bearings with a circumferential parallel arrangement of microtexture.

Originality/value

The novel composite microtexture with columnar convex-concave is proposed, and the computational model of thrust bearings is set. The influence of surface roughness and turbulent flow on the bearing performance should be considered for better conforming with engineering practice. The effect of microtexture depth, arrangement method and distribution position on the lubrication performance of the compound microtexture thrust bearing is investigated, which is of great significance for improving tribology, thrust bearings and surface microtexture theory.

Abstract

Purpose

The purpose of this research was to examine the influence of entrepreneurial orientation on social performance and the influence of social performance on financial performance of microfinance institutions (MFIs) in Indonesia. These tests use environmental dynamism as antecedents.

Design/methodology/approach

The research was conducted on a sample of 235 CEOs/top leaders of MFIs spread across all provinces in Indonesia. Data collection used survey questionnaires. Data testing used SPSS version 25, and structural modeling used Amos version 25.

Findings

The findings show that entrepreneurial orientation significantly influences the social performance of MFIs in Indonesia. Entrepreneurial orientation does not influence financial performance but must go through social performance mediation. Social performance has a significant effect on financial performance. The importance of MFIs improves social performance (depth and breadth of reach) to improve financial performance.

Practical implications

MFIs need to increase social contribution and responsibility to improve social performance which will impact financial performance.

Originality/value

Entrepreneurial orientation influence on financial performance goes through social performance. Social performance includes the depth of the reach to contribute to improving the quality of life of people experiencing poverty around the MFI's operations and the social responsibility of MFIs to the community through scholarships, free medical assistance, basic food assistance and building/renovating houses of worship and others.

Abstract

Purpose

The purpose of this study is to investigate the effects of celebrity endorsers on consumer advocacy, customization and entertainment intentions based on the notion of the stimulus–organism–response (SOR) framework. In addition, this study aims to examine the mediating and moderating role of customization and entertainment intentions on the proposed relationships. The authors also intend to highlight the comparative effects between male and female young social media consumers on those proposed associations.

Design/methodology/approach

In the pursuit of comprehensive and rigorous data collection, this study adopted a quantitative methodology using a meticulously crafted questionnaire. The questionnaire survey was conducted in major cities of Malaysia using the convenience and snowball sampling techniques. A total of 576 responses were collected, even though 549 retorts were used for data analysis. In this investigation, the authors strategically used covariance-based structural equation modeling through the use of AMOS v. 24 as the primary data analysis tool. Augmenting the analytical depth, the authors also conducted a supplementary bootstrap analysis. The additional layers of examination were crucial for appraising the mediating and moderating effects inherent within the model, in which the PROCESS MACRO v.4.20 was used.

Findings

The results of this study revealed the significant direct positive effects of celebrity endorsers on consumer customization, entertainment and advocacy intentions. Consumer customization and entertainment intentions also found significant direct affirmative effects on consumer advocacy intention, along with the significant direct positive effects of consumer entertainment intention on consumer customization intention. The results further revealed that consumer customization and entertainment intentions cannot mediate the relationship between celebrity endorsers and advocacy intention. The entertainment intention also declined the mediating effects between celebrity endorsers and consumer customization intention. On the contrary, consumer customization intention significantly and positively, and entertainment intention also significantly but negatively, moderate the association between celebrity endorsers and consumer advocacy intention. This study also illustrates that the effects of those examined relationships differ between male and female young social media consumers.

Originality/value

This study investigates the impact of celebrity endorsers on consumer behavior, focusing on their customization, entertainment and advocacy intentions. It extends current SOR framework, enhances source credibility theory, fills gaps in the literature on social media brand engagement and underscores the significance of customization and entertainment intentions. The findings provide insights for managers aiming to harness consumer brand advocacy through celebrity endorsers effectively.

Abstract

Purpose

The study aims to investigate students' attitudes toward using technology for micro-credential programs (MCPs) and their behavioral intention toward using MCPs for learning and enhancing their skills. The study also intends to investigate the moderating influence of labor market conditions (LMC).

Design/methodology/approach

A closed-ended questionnaire is employed to collect data from 474 participants through a convenience sample, from the university students in Karachi. Two theoretical frameworks are used in the study: technology acceptance model (TAM) and self-determination theory (SDT). The partial least squares structural equation modeling (PLS-SEM) technique is used to analyze data.

Findings

Findings reveal significant and positive relationships between all variables, except controlled motivation (CM) and perceived challenges. Moreover, the moderation results ascertain that the labor market does not moderate the relationship between attitude toward using technology for MCPs and students' behavioral intention toward using MCPs for learning.

Originality/value

The study seeks to understand students' attitudes and behavioral intentions toward using technology for MCPs. Also, the moderating effect of LMC is highlighted in understanding the impact of the attitude to use technology (AT) for MCPs and behavioral intentions in higher educational institutions (HEIs) in Pakistan. The study highlights intuitive practical implications for students of HEIs, universities and digital credential program providers.

Abstract

Purpose

The prevailing view in the existing literature is that open innovations (OI) increase the innovative performance of enterprises. The author examines whether the same OI practices are equally important for sole entrepreneurs, micro firms, small firms, medium-sized and large enterprises in introducing radical innovations and which set of OI practices is best for a firm, given the firm's size.

Design/methodology/approach

In this study probit models were used on a sample of 915 innovative Serbian enterprises.

Findings

OI is important for all enterprises introducing radical innovations. However, not all OI practices are equally effective in each enterprise size group. The set of OI practices leading to radical innovations depends on the firm size. Cooperation with others is not important for sole entrepreneurs and micro and large companies in introducing radical innovations. Still, cooperation's role is predominant in small and medium-sized enterprises. Also, certain OI practices are important for all enterprises, whilst others do not contribute to radical innovations, regardless of the firm size.

Practical implications

Owners/managers can save considerably by avoiding the allocation of resources to OI practices that result in little to no contribution to radical product commercialisation. At the macroeconomic level, these findings can help policymakers create adequate (tailor-made) public policies to achieve innovation in each specific group of firms.

Originality/value

This study demonstrates that not all OI practices are equally important for achieving radical production solutions in each group of enterprises.

Abstract

Purpose

This study aims to examine the impact of renewable energy consumption on agricultural productivity while accounting for the effect of financial inclusion and foreign direct investment in Brazil, Russia, India, China and South Africa (BRICS) countries during 2000–2020.

Design/methodology/approach

The study has used the latest data from World Bank and International Monetary Fund databases. The dependent variable in the study is agricultural productivity. Renewable energy consumption, carbon emissions, financial inclusion and foreign direct investment are independent variables. Autoregressive distributed lag (ARDL) approach was used to examine the short-run and long-run impact of renewable energy consumption, carbon emissions, foreign direct investment and financial inclusion on agricultural productivity.

Findings

The findings imply that consumption of renewable energy, carbon emissions and foreign direct investment have a positive impact on agricultural productivity while financial inclusion in terms of access does not seem to have any significant impact on agricultural productivity. Providing farmers, access to financial services can be beneficial, but its usage holds more importance in impacting rural outcomes. The problem lies in the fact that there is still a gap between access and usage of financial services.

Research limitations/implications

Policymakers should encourage the increase in the usage of renewable energy and become less reliant on non-renewable energy sources which will eventually help in tackling the problems associated with climate change as well as enhance agricultural productivity.

Originality/value

Most of the earlier studies were based on tabular analysis without any empirical base to establish the causal relationship between determinants of agricultural productivity and renewable energy consumption. These studies were also limited to a few regions. The study is one of its kind in exploring the severity of various factors that determine agricultural productivity in the context of emerging economies like BRICS while accounting for the effect of financial inclusion and foreign direct investment.

Abstract

Purpose

The purpose of this study is to explore the suggestions that construction processes could be considerably improved by integrating building information modelling (BIM) with 3D laser scanning technologies. This case study integrated 3D laser point cloud scans with BIM to explore the effects of BIM adoption on ongoing construction project, whilst evaluating the utility of 3D laser scanning technology for producing structural 3D models by converting point cloud data (PCD) into BIM.

Design/methodology/approach

The primary data acquisition adopted the use of Trimble X7 laser scanning process, which is a set of data points in the scanned space that represent the scanned structure. The implementation of BIM with the 3D PCD to explore the precision and effectiveness of the construction processes as well as the as-built condition of a structure was precisely captured using the 3D laser scanning technology to recreate accurate and exact 3D models capable of being used to find and fix problems during construction.

Findings

The findings indicate that the integration of BIM and 3D laser scanning technology has the tendency to mitigate issues such as building rework, improved project completion times, reduced project cost, enhanced interdisciplinary communication, cooperation and collaboration amongst the project duty holders, which ultimately enhances the overall efficiency of the construction project.

Research limitations/implications

The acquisition of data using 3D laser scanner is usually conducted from the ground. Therefore, certain aspects of the building could potentially disturb data acquisition; for example, the gable and sections of eaves (fascia and soffit) could be left in a blind spot. Data acquisition using 3D laser scanner technology takes time, and the processing of the vast amount of data acquired is laborious, and if not carefully analysed, could result in errors in generated models. Furthermore, because this was an ongoing construction project, material stockpiling and planned construction works obstructed and delayed the seamless capture of scanned data points.

Originality/value

These findings highlight the significance of integrating BIM and 3D laser scanning technology in the construction process and emphasise the value of advanced data collection methods for effectively managing construction projects and streamlined workflows.

Abstract

Purpose

Organic food consumption has received great attention due to the increase in consumer environmental and health concerns. This study intends to analyse how customers' green purchasing intentions for organic food are affected by internal factors of attitude and health consciousness and external factors of social norms and environmental concern, as well as how green trust operates as a moderator between green purchase intention and actual purchase.

Design/methodology/approach

A quantitative research methodology was employed in this study. The data (n = 323) were gathered via a self-administered questionnaire. The respondents, who were current purchasers of organic food, were chosen through a purposive sampling technique. Data were analysed using exploratory factor analysis and structural equation modelling with the aid of IBM SPSS 25.0 and AMOS 25.

Findings

The results reveal that customers' green purchase intention for organic products is positively influenced by internal factors (attitude and health consciousness) and external factors (social norms and environmental concern). This study also shows the moderating effect of green trust on intention and action, demonstrating the necessity of building green trust among customers to diminish green purchasing inconsistency.

Practical implications

The study's results have ramifications for producers of organic goods, merchants and market oversight organizations. Establishing a viable strategy while considering customers' concerns about health and the environment is necessary. The formulated strategy must target specific customer niches, therefore strengthening customers' trust in and understanding of organic food items, which will in turn diminish green purchasing inconsistency in the organic industry.

Originality/value

This study contributes to the existing literature by extending the Theory of Planned Behaviour model to organic food consumption and by visualizing how various factors (internal, external and green trust) affect a consumer's inclination to make organic food purchases. The authors added to the empirical evidence that green trust plays a crucial role in stimulating green buying intentions into behaviour and ultimately diminishing green purchasing inconsistency.

Abstract

Purpose

This study aims to explore how individual-level and organizational-level factors interact to influence pay information (PI) seeking and PI sharing preferences in PI conversations (i.e. the face-to-face communications context). The authors examine how an individual’s judgment of their pay relative to others – or pay equity perception – affects their PI seeking and PI sharing preferences and how those relationships are affected by organizationally created pay transparency policies and pay transparency practices.

Design/methodology/approach

Using a 2 × 2 × 2 experimental design on the MTurk platform, the authors used a scenario-based prompt method to manipulate employee perceptions of pay equity and organizational pay transparency and tested those effects on employee pay disclosure preferences. The authors consider both pay policy and pay practice dimensions of pay transparency and both PI seeking and PI sharing dimensions of pay disclosure preferences. The final sample had 597 participants.

Findings

The authors find employees’ pay equity perceptions are negatively related to PI seeking behaviors and are even more so when organizations have restrictive pay transparency policies. Also, both pay transparency policy and pay transparency practice increase PI sharing preferences.

Originality/value

The authors provide insight into how individual perceptions drive pay disclosure motivations and the role of organizational policy and practice in influencing pay disclosure preferences within PI conversations. The authors provide insight into the antecedents that shape pay disclosure preferences, which lead to a both PI conversations among coworkers and an increase in one’s pay understanding. This study shows the contextual nature of PI seeking and PI sharing preferences, which are a motivational antecedent to pay-related sensemaking behaviors.

Abstract

Purpose

This study aims to determine the antecedents that influence attitudes towards the use of environmentally friendly household appliance products and consumers' green purchase intention among consumers in Harare, Zimbabwe.

Design/methodology/approach

Data were collected from 329 consumers in Harare, Zimbabwe's commercial capital who were served from five using a structured questionnaire via an online web-based cross-sectional survey. Hypothesised relationships were tested through structural equation modelling with the aid of Smart PLS software.

Findings

Green product awareness, social influence, perceived benefit and attitude towards green appliances were found to have a significant positive effect on green purchase intention.

Research limitations/implications

The study's findings may not be generalised to other contexts as sample data was only collected in Zimbabwe. Complementary cross-sectional research studies can be done in other parts of the world to enable cross-cultural comparisons and methodological validations.

Practical implications

The green appliance and energy saving practices are vastly growing, with many multinational appliance companies introducing green products within their product lines and adopting the concept of sustainability through modifications in production, design and consumption of household appliance products that encompass fewer harmful consequences on the environment in response to their concerns about the scarcity of natural resources, environmental well-being and the potential detriment of future generations.

Originality/value

Notwithstanding the limitations of the current study, the results have the potential to contribute to an improved understanding of influence attitudes towards the use of environmentally friendly household appliance products.
