This study aims to build on social comparison theory to develop a theoretical model of leader–member exchange (LMX) relationship to workplace ostracism through perceived organizational status by coworkers and envy. This study further proposes that warmth and competence may potentially moderate these two indirect effects.

This study tested the hypotheses in a battery manufacturing company located in South China by a survey of 216 employees organized in 55 work teams, using different sources. Additionally, the authors conduct two online vignette experiments to test this study’s mediation, proving the causality.

The authors found that high-level LMX leads to both envy and perceived organizational status by coworkers, which results in a mixed blessing on workplace ostracism toward the employee with high-level LMX. The focal employee’s warmth and competence moderate these indirect relationships.

The authors use LMX to explore antecedents of workplace ostracism and explain how and when these focal employees suffer workplace ostracism from their coworkers. The authors extend the research on LMX by examining the interpersonal risk of being a focal employee. The authors discover two critical boundary conditions – warmth and competence.

This study suggests that it is important to balance the level of the differential LMX; appropriately endorsing other members is a good way to avoid eliciting envy and opposition. Meanwhile, person-oriented citizenship behaviors such as demonstrations of concern or help may shortly build up an employee’s warm impression on their coworkers.

By discovering the bright and dark sides of LMX, this paper has the potential to advance theories on LMX and workplace ostracism. Therefore, the authors believe the current research will have an important impact on relevant research in the future.

This study aims to explore the factors affecting sustainable workplace remodeling in Saudi Arabia.

A literature review was conducted, resulting in 30 factors grouped into five categories. A questionnaire was designed and tested, and stakeholders including architects/engineers (A/Es), contractors and facilities managers were surveyed to evaluate the importance of these factors. The responses were analyzed to determine the relative importance index (RII), importance rating (IR) and ranking of each factor.

All 30 factors were evaluated as “Extremely Important” and “Very Important” in the collective assessment conducted by the three stakeholder categories. The findings revealed that the key factors, unanimously highlighted by all groups, include “The highest-ranking factors Constrained budget for the project”, “Availability of an experienced contractor in the remodeling field”, “Compliance with safety codes and standards”, “Underestimation of project complexity” and “Availability of specifications”.

The study presents an approach for assessing stakeholder consensus, using the RII and Spearman’s rank correlation coefficient to analyze the results. This approach aims to improve understanding of how various stakeholders influence and perceive sustainability in construction projects.

The study offers guidance for various stakeholders, to integrate sustainable practices into their operations. It emphasizes communication, implementing cost-efficient designs and ensuring compliance with sustainability standards to enhance the longevity and efficiency of remodeled workplaces.

The study adds to the current knowledge base by providing insights into sustainable practices of workplace remodeling specific to the context of Saudi Arabia.

Despite the large corpus of literature on fashion consciousness (FC) and fashion involvement (FI), both terms are often used synonymously, resulting in conflicting or mixed results. We address this limitation by offering a critical analysis of FC and FI, with a specific focus on their measurements.

A snowball sample survey of 720 respondents were conducted for factor analysis aimed at assessing reliability and validity. Specifically, following discriminant and concurrent validity between FC and FI.

Our empirical research underscores the clear distinction between FC and FI in terms of their theoretical definitions and measurements. We strongly discourage their use as interchangeable/synonymous terms or use of other potentially related terminology.

Our contribution clarifies the differences between FI and FC. While acknowledging that authors may resort to linguistic repetition in their discourse, we advocate for consistently using the precise terms “fashion involvement” and “fashion consciousness” whenever feasible. This study has the potential to inform future knowledge development and literature reviews in the field.

Drawing on conservation of resources (COR) theory, this research aims to advance the current understanding of leader boundary spanning by examining its effect on task performance, psychological mechanism and boundary conditions.

The empirical data were gathered by a paper-and-pencil survey from 155 employee-supervisor dyads working in various industries.

Our results indicated that leader boundary spanning is positively related to task performance, mediated by employees’ enhanced self-efficacy. Moreover, the results indicated that the positive effect of leader boundary spanning on task performance via enhanced self-efficacy is strengthened when the level of abusive supervision is low or when the level of an employee’s emotional exhaustion is high.

Organizations should find a way to facilitate leaders to engage in boundary spanning behaviors since a leader’s boundary spanning behavior enhances task performance through employee’s self-efficacy. Additionally, it is crucial to establish policies and provide training sessions to reduce the occurrence of abusive supervision in the workplace.

This study gives insights into the current literature by uncovering whether, how and under what circumstances boundary spanning leaders exert influences on task performance via employees’ self-efficacy. Our results showed that the positive effect of leader boundary spanning is likely to be strengthened when boundary spanners do not abuse their employees or when employees are in need of additional resources.

This study aims to enhance pedestrian safety by investigating the slip resistance of facility floors with ceramic tile surfaces and identifying critical surface roughness parameters that influence slip resistance.

Dynamic friction tests and comprehensive surface roughness analyses were conducted on ceramic tiles. Statistical analysis identified optimal roughness ranges for key parameters (R_a, R_p, R_t, R_z and R_v) to ensure the dynamic friction coefficient exceeds 0.5 to meet safety requirements. This study assessed different textures under dry, damp and foamy conditions.

The findings reveal that ceramic tile surfaces with higher peak heights and deeper valleys provide superior traction, particularly in damp and foamy conditions. The results demonstrate that specific surface textures can effectively mitigate slip and fall hazards by enhancing grip and increasing surface interaction points. This study establishes optimal roughness ranges for the critical parameters, providing a robust framework for improving slip resistance.

This study offers practical guidelines for designing safer ceramic tiles, emphasising the importance of tailored surface roughness to improve traction. It highlights the importance of considering environmental factors in slip resistance assessments, offering valuable insights for manufacturers, designers and policymakers. By focusing on specific surface textures, this study advances the development of safer built environments in public facilities. Future research directions should explore a broader range of tile finishes, footwear types and contaminant scenarios to refine the understanding of traction performance further.

The continuing development of digital technologies creates expanding opportunities for information transparency. Consumers use social media to provide online reviews that are focused on changing levels of consumer trust. This study examines the effect of perceived risk that prompts consumers to search for online reviews in the context of food safety.

Commitment-trust theory forms the theoretical lens to model changes in consumer trust resulting from online reviews. Consumer-based questionnaire surveys collected data to test the structural model, using structural equation modelling (SEM).

The findings show when consumers perceive high levels of risk, they use social media to obtain additional product-related information. The objective, unanimous, evidential and noticeable online reviews are perceived as informative to consumers. Perceived informativeness of positive online reviews is found to increase consumers trust and, in turn, increase their purchase intentions.

The findings contribute to the knowledge of online review-based trust literature and provide far-reaching implications for information system (IS)-practitioners in business.

As lubricating oils are used, their performance deteriorates and they become contaminated. The purpose of this paper is to investigate the lubrication performance of reclaimed 5 W-30 a fully synthetic used engine oil (UEO) with wear tests after refining it from a solvent-based extraction method using solvent (1-PrOH) and adsorbent materials such as cement, celite and deep eutectic solvent (DES).

The treated oil mixtures were prepared by blending engine oils with various adsorbent materials at 5% (w/w) in organic 1-PrOH solvent at a UEO: solvent ratio of 1:2 (w/w). The measurement of kinematic viscosity, density, the total acid number (TAN) and elemental analysis of oil samples was done by the ASTM standards D445/D446, D4052, D974 and D6595, respectively. Adsorbents and treated oil samples characterized by SEM-EDX, FTIR and UV analysis, respectively. Meanwhile, lubricating performance in tribological applications was evaluated through the wear test device using a rotating steel alloy 1.2379 cylinder and a stationary 1.2738 pin under 20, 40 and 80 kg load conditions. Worn surface analysis was done with SEM and 2.5D images.

It was found that when using the combination of cement and celite as an adsorbent in the reclamation of used engine oil demonstrated better lubricant properties. The properties of used engine oil were improved in the manner of kinematic viscosity of 32.55 from 68.49 mm²/s, VI (Viscosity index) value of 154 from 130, TAN of 3.18 from 4.35 (mgKOH/g) and Fe content of 11 from 32 mg/L. The anti-wear properties of used engine oil improved by at least 32% when 5% cement and 5% celite adsorbent materials were used together.

The paper is based on findings from a fully synthetic 5 W-30 A5 multi-grade engine lubrication oil collected after driving approximately 12.000 km.

The results are significant, as they suggest practical regeneration of used engine oil is achievable. Additionally, blending fresh oil with reclaimed used engine oil in a 1:1 ratio reduced wear loss by over 10% compared to fresh oil.

Reusing used engine oils can reduce their environmental impact and bring economic benefits.

This study showed that the properties of UEO can be enhanced using the solvent extraction-adsorption method. Furthermore, the study provided valuable insights into the metal concentrations in engine oil samples and their impact on lubrication performance. The order of the number of the grooves quantity and the possibility of the observed scuffing region trend relative to the samples was UEO > 5W-30 fresh oil > Treated oil sample with the adsorbent cement and celite together.

This study aims to develop customer trust through information quality, customer awareness, and perceived value. This study is motivated by the hustle and bustle occurred as the result of the socialization of MyPertamina, a digital payment service for subsidized fuel customers in 11 areas of 4 provinces in Indonesia. The hustle and bustle can be viewed as customer distrust of MyPertamina. However, customer trust is a business success key. Is MyPertamina a solution or problem maker for customers to buy subsidized fuel?

The design of this study is survey. Primary data are collected through questionnaires sent to subsidized fuel customers in the socialization areas of MyPertamina. The data are processed using SPSS and Amos programs.

PV, IQ and CA, respectively, can develop CT on MyPertamina. Although the PV cannot strengthen the effect of CA on CT, the construct can strengthen the effect of IQ on CT.

Indonesian Government via Pertamina, a state-owned enterprise, must develop CT through IQ, CA and PV to succeed the application of MyPertamina.

This study develops IQ, CA and PV based on technology acceptance model and theory of reasoned action to develop CT on MyPertamina.

This paper aims to examine the structure and content of religious tourism destination image through the reviews of visitors to Makkah and Medina, two of the world’s most popular Muslim pilgrimage sites.

This is an exploratory netnographic study of the 913 reviews posted on TripAdvisor from 2018 to 2022. The structure (dimensions and attributes) and content (variables) comprising the construct of religious tourism destination image emerge through manual thematic analysis and confirmed through content analysis.

Religious tourism destination image is a three-dimensional – cognitive, affective and conative – construct comprising both religion-specific, generally sacred and secular variables in a single, indivisible crystallization of experience.

Destination marketing organizations and marketers of tourism enterprises should regularly analyze visitor reviews posted on social media and carefully manage all variables of the religious tourism destination image, specifically stressing the religious aspect.

To the best of the authors’ knowledge, this is the first systematic analysis of the structure and content of religious tourism destination image based on detailed consumer evaluations and unprompted storytelling.

This study aims to examine how an organization’s innovation capability could influence research and development (R&D) performance. It also investigates if industry–academic knowledge transfer has a moderating relationship between organizational innovation capability and exploration and exploitative innovation in improving the R&D performance of the organizations.

Based on the literature and dynamic capability view, a conceptual model was developed and then validated using the partial least squares-structural equation modeling technique considering 387 responses from academicians and industry personnel.

The study found that industry–academic knowledge transfer has a significant moderating impact toward improving innovation capability, organizations’ R&D performance and exploration innovation. However, it has an insignificant moderating impact on improving innovation capability and exploitative innovation.

Organizational innovation capability is characterized by both exploratory and exploitative innovation. Both types of innovation support the R&D performance of an organization. Also, organizations that closely work with academic institutions could gain significant R&D knowledge from academic expertise. This study provides food for thought for the academic community as well as industry policymakers.

There are significant opportunities for academic institutions to gain practical knowledge from industry which can help them to accelerate their R&D activities. However, transferring knowledge between industry and academia has challenges related to intellectual property, patents and so on. Not much research has been conducted in this area. Thus, the proposed research model is unique and adds to the existing literature.
